Abstract:
Background While multiple studies have examined the brain functional correlates of reward, meta-analyses have either focused on studies using the monetary incentive delay (MID) task, or have adopted a broad strategy, combining data from studies using both monetary and non-monetary reward, as probed using a wide range of tasks. Objective To meta-analyze fMRI studies that used monetary reward and in which there was a definable cue-reward contingency. Studies were limited to those using monetary reward in order to avoid potential heterogeneity from use of other rewards, especially social rewards. Studies using gambling or delay discounting tasks were excluded on the grounds that reward anticipation is not easily quantifiable. Study eligibility English-language fMRI studies (i) that reported fMRI findings on healthy adults; (ii) that used monetary reward; and (iii) in which a cue that was predictive of reward was compared to a no win (or lesser win) condition. Only voxel-based studies were included; those where brain coverage was incomplete were excluded. Data sources Ovid, Medline and PsycInfo, from 2000 to 2020, plus checking of review articles and meta-analyses. Data synthesis Data were pooled using Seed-based d Mapping with Permutation of Subject Images (SDM-PSI). Heterogeneity among studies was examined using the I2 statistic. Publication bias was examined using funnel plots and statistical examination of asymmetries. Moderator variables including whether the task was pre-learnt, sex distribution, amount of money won and width of smoothing kernel were examined. Results Pooled data from 45 studies of reward anticipation revealed activations in the ventral striatum, the middle cingulate cortex/supplementary motor area and the insula. Pooled data from 28 studies of reward delivery again revealed ventral striatal activation, plus cortical activations in the anterior and posterior cingulate cortex. There was relatively little evidence of publication bias. Among moderating variables, only whether the task was pre-learnt exerted an influence. Conclusions According to this meta-analysis monetary reward anticipation and delivery both activate the ventral but not the dorsal striatum, and are associated with different patterns of cortical activation.

Abstract:
In natural behavior, animals have access to multiple sources of information, but only a few of these sources are relevant for learning and actions. Beyond choosing an appropriate action, making good decisions entails the ability to choose the relevant information, but fundamental questions remain about the brain’s information sampling policies. Recent studies described the neural correlates of seeking information about a reward, but it remains unknown whether, and how, neurons encode choices of instrumental information, in contexts in which the information guides subsequent actions. Here we show that parietal cortical neurons involved in oculomotor decisions encode, before an information sampling saccade, the reduction in uncertainty that the saccade is expected to bring for a subsequent action. These responses were distinct from the neurons’ visual and saccadic modulations and from signals of expected reward or reward prediction errors. Therefore, even in an instrumental context when information and reward gains are closely correlated, individual cells encode decision variables that are based on informational factors and can guide the active sampling of action-relevant cues.

Abstract:
A key step of decision making is to determine the value associated with each option. The evaluation process often depends on the accumulation of evidence from multiple sources, which may arrive at different times. How evidence is accumulated for value computation in the brain during decision making has not been well studied. To address this problem, we trained rhesus monkeys to perform a decision-making task in which they had to make eye movement choices between two targets, whose reward probabilities had to be determined with the combined evidence from four sequentially presented visual stimuli. We studied the encoding of the reward probabilities associated with the stimuli and the eye movements in the orbitofrontal (OFC) and the dorsolateral prefrontal (DLPFC) cortices during the decision process. We found that the OFC neurons encoded the reward probability associated with individual pieces of evidence in the stimulus domain. Importantly, the representation of the reward probability in the OFC was transient, and the OFC did not encode the reward probability associated with the combined evidence from multiple stimuli. The computation of the combined reward probabilities was observed only in the DLPFC and only in the action domain. Furthermore, the reward probability encoding in the DLPFC exhibited an asymmetric pattern of mixed selectivity that supported the computation of the stimulus-to-action transition of reward information. Our results reveal that the OFC and the DLPFC play distinct roles in the value computation during evidence accumulation.

Abstract:
An association of food sources with odors prominently guides foraging behavior in animals. To understand the interaction of olfactory memory and food preferences, we used glucose-averse (GA) German cockroaches. Multiple populations of cockroaches evolved a gustatory polymorphism where glucose is perceived as a deterrent and enables GA cockroaches to avoid eating glucose-containing toxic baits. Comparative behavioral analysis using an operant conditioning paradigm revealed that learning and memory guide foraging decisions. Cockroaches learned to associate specific food odors with fructose (phagostimulant, reward) within only a 1 h conditioning session, and with caffeine (deterrent, punishment) after only three 1 h conditioning sessions. Glucose acted as reward in wild type (WT) cockroaches, but GA cockroaches learned to avoid an innately attractive odor that was associated with glucose. Olfactory memory was retained for at least 3 days after three 1 h conditioning sessions. Our results reveal that specific tastants can serve as potent reward or punishment in olfactory associative learning, which reinforces gustatory food preferences. Olfactory learning, therefore, reinforces behavioral resistance of GA cockroaches to sugar-containing toxic baits. Cockroaches may also generalize their olfactory learning to baits that contain the same or similar attractive odors even if they do not contain glucose.

Abstract:
Hospitals are considered as life saving institutions and the service quality through the better performance of employees is an essential parameter to serve thecustomers. To sustain within the competition and to achieve the competitive advantage, it is vital to focus on the attitudes and job performance of the employees. Failure to design appropriate compensation system will have unfavorable impact on productivity and job satisfaction and overall effectiveness of the hospital. Though compensation in terms of salary increment, reward, health insurance, workers compensation, retirement plan and paid holiday were applied in the study hospital, the effect of such compensation was not tested still. Hence, the aim of this paper is to assess the effect of compensation on job performance of hospital employees. In order to address the objective, both primary and secondary sources of data were used. The required data was collected from 206 employees identified through stratified random sampling technique. The data collected through questionnaire was analysed by SPSS ( version 21) and descriptive statistics such as frequency, percentage, mean and standard deviation and inferential statistics such as onesample t-test, correlation and multiple linear regressions were used arrive the meaningful results. The findings show that 65% of the variance of the employee performance was significantly explained by three independent variables namely; compensation, salary and rewards. It is concluded that there is a significant effect of salary, reward and indirectcompensation on employee job performance in the hospital. It is recommended that hospital management needs to improve its compensation system time to tome and further studies to be conducted to investigate the strategies used to deal with the problems of employees recruitment and retention among others.

Abstract:
Abstract Q-learning is a method of reinforcement learning that employs backwards stagewise estimation to identify sequences of actions that maximize some long-term reward. The method can be applied to sequential multiple-assignment randomized trials to develop personalized adaptive treatment strategies (ATSs)—longitudinal practice guidelines highly tailored to time-varying attributes of individual patients. Sometimes, the basis for choosing which ATSs to include in a sequential multiple-assignment randomized trial (or randomized controlled trial) may be inadequate. Nonrandomized data sources may inform the initial design of ATSs, which could later be prospectively validated. In this paper, we illustrate challenges involved in using nonrandomized data for this purpose with a case study from the Center for International Blood and Marrow Transplant Research registry (1995–2007) aimed at 1) determining whether the sequence of therapeutic classes used in graft-versus-host disease prophylaxis and in refractory graft-versus-host disease is associated with improved survival and 2) identifying donor and patient factors with which to guide individualized immunosuppressant selections over time. We discuss how to communicate the potential benefit derived from following an ATS at the population and subgroup levels and how to evaluate its robustness to modeling assumptions. This worked example may serve as a model for developing ATSs from registries and cohorts in oncology and other fields requiring sequential treatment decisions.

Abstract:
Research on teacher collaboration emphasizes the key role of collaborative culture for teachers’ functioning; however, there is little empirical evidence to investigate its relationship with knowledge sharing among university ESP teachers. In the present study, the relationship between EFL teachers’ collaborative climate and knowledge sharing was sought. The data were collected through two surveys of 328 Iranian ESP teachers. A Pearson correlation was carried out to investigate the relationship between the two variables of the study. A multiple regression analysis was also run to examine if ESP teachers’ collaborative climate predicts their knowledge sharing. A follow-up interview with 13 ESP teachers was conducted to consolidate the findings and explore the contribution of teachers’ collaborative climate to their knowledge sharing. The Pearson correlation coefficient test demonstrated a significant positive correlation for four measures (organizational culture, the head of department, teachers’ attitude, workgroup support), and the collaborative climate. The results of the multiple regression also indicated that four subscales of collaborative climate were the predictors of ESP teachers’ attitude towards knowledge sharing. Analysis of the interview data, on the other hand, indicated how teachers’ collaborative climate contributes to their knowledge sharing through one of the four main sources, namely helpful atmosphere, encouragement received from the heads of departments, the expectation of reward, and work group support. In line with these findings, several practical recommendations were offered.

Abstract:
Abstract Objectives The 2020 dietary guidelines specifically recommended a decrease in sugar intake. Reward-related, brain-based models of overeating and obesity suggest that increased intake of highly palatable foods is linked to decreased dopaminergic (striatal and prefrontal) brain functioning. This reduction acts to increase consumption of food to achieve pleasure. Here, we examined whether increased dietary intake of sugar and fat would be associated with increased activation in reward-related brain regions during anticipation of a sugar sweetened beverage (SSB), but decreased activation during SSB receipt. Methods Young adults (n = 100, age = 21.8 ± 2.4 y, BMI = 23.3 ± 3.5, 70% female) underwent an fMRI scan examining brain responses to receipt of a SSB, a tasteless rinse, and response cue-induced anticipation of these tastes. The Block Food Frequency Questionnaire (FFQ) was used to assess average dietary intake, % daily caloric intake from SSBs, sugar, sugar from SSBs and fat. These were correlated with whole-brain BOLD responses to SSB anticipation and receipt contrasts (e.g., SSB > rinse). Significance was corrected for multiple comparisons; pFWE < .05. Results Increased consumption of sugar calories from SSBs was correlated with decreased activity in regions associated with dopamine (posterior midbrain, dorsolateral/orbitofrontal cortices) and taste processing regions (postcentral gyrus) during receipt of SSB (> rinse). Conclusions These results directly support previous research (Burger & Stice 2012; AJCN) demonstrating that increased consumption of highly palatable foods is associated with reduced dopaminergic brain response during consumption specifically of those foods. Critically, we demonstrate these effects with SSBs which are far more widely consumed. Our results were specific to increased intake of sugar calories from SSBs and not total calories from SSBs or total sugar calories, suggesting that added sugars in these beverages have the potential to lead to altered frontostriatal brain responses.

Abstract:
Data from multiple sources point to the desire for revenge in response to grievances or perceived injustices as a root cause of violence, including firearm violence. Neuroscience and behavioral studies are beginning to reveal that the desire for revenge in response to grievances activates the same neural reward-processing circuitry as that of substance addiction, suggesting that grievances trigger powerful cravings for revenge in anticipation of experiencing pleasure. Based on this evidence, the authors argue that a behavioral addiction framework may be appropriate for understanding and addressing violent behavior. Such an approach could yield significant benefits by leveraging scientific and public health-oriented drug abuse prevention and treatment strategies that target drug cravings to spur development of scientific and public-health-oriented “gun abuse” prevention and treatment strategies targeting the revenge cravings that lead to violence. An example of one such “motive control” strategy is discussed. Approaching revenge-seeking, violence, and gun abuse from the perspective of compulsion and addiction would have the added benefit of avoiding the stigmatization as violent of individuals with mental illness while also acknowledging the systemic, social, and cultural factors contributing to grievances that lead to violent acts.

Abstract:
A growing body of evidence has demonstrated that multiple sources of salience tune attentional sets toward aspects of the environment, including affectively and motivationally significant categories of stimuli such as angry faces and reward-associated target locations. Recent evidence further indicates that objects that have gained personal significance through ownership can elicit similar attentional prioritization. Here we discuss current research on sources of attentional prioritization that shape our awareness of the visual world from moment to moment and the underlying neural systems and contextualize what is known about attentional prioritization of our possessions within that research. We review behavioral and neuroimaging research on the influence of self-relevance and ownership on cognition and discuss challenges to this literature stemming from different modes of conceptualizing and operationalizing the self. We argue that ownership taps into both “self-as-object,” which characterizes the self as an object with a constellation of traits and attributes, and “self-as-subject,” which characterizes the self as an agentic perceiver and knower. Despite an abundance of research probing neural and behavioral indices of self-as-object and its effects on attention, there exists a paucity of research on the influence of self-relevance of attention when self is operationalized from the perspective of a first-person subject. To begin to address this gap, we propose the Self as Ownership in Attentional Prioritization (SOAP) framework to explain how ownership increases salience through attention to external representations of self-identity (i.e., self as object) and attention to contextually mediated permission to act (i.e., self as subject).

Abstract:
Purpose The purpose of this paper is to explore the reasons for the continuing “gap” between UK retail academic research and practice. A relationship marketing (RM) lens, focussing on relationship antecedents, is used to develop a deeper understanding of the barriers to collaboration and propose new solutions to close the gap. Design/methodology/approach The paper adopts a qualitative methodology to compile the evidence, using multiple data sources to identify the dynamics of the retail academic-practitioner divide. Findings The research illustrates a marked absence of the majority of the customer focussed, seller focussed and dyadic antecedents, essential for effective relational exchanges, and highlights that at the heart of the problem lies a lack of shared understanding of mutual relationship benefits with academics currently neither motivated nor incentivised to develop such relationships. Research limitations/implications Further research is needed to explore what characterises a successful sustainable research relationship. There is also a pressing need to understand the experience, skills and knowledge of “boundary spanners” who operate successfully in both academic and business cultures. Practical implications Universities should adopt a strategic approach towards building relationships with retailers based upon relationship antecedents. Reward structures should be developed to encourage academics to develop research relationships. Resources should be allocated to better defining and communicating the benefits of a university research relationship with retailers. Originality/value There has been limited empirical research on the academic-practitioner gap within the context of the UK retail sector. The RM lens draws attention to new insights about barriers to successful relationships and generates concrete ideas for closing the gap moving forward.

Abstract:
Purpose – The purpose of this paper is to examine the critical features and outcomes of an Australian collaborative university- and school-based immersion project for mentoring final year pre-service primary teachers in the area of special education as they embed theory and practice in inclusive classrooms for a full year, to respond to diverse student needs. Design/methodology/approach – Using a three-year qualitative study design, data were gathered through pre surveys and post surveys, two one-to-one semi-structured interviews, and reflexive journal entries. Analysis using triangulation of data sources and inter-rater reliability was employed to reach consensus on the key themes. Findings – Findings suggest that mentors proved critical to reducing pre-service teacher anxieties and to enhancing their personal and professional knowledge, confidence and skills as they differentiated instruction and assessment techniques to cater for students with a diverse range of abilities. Research limitations/implications – This research suggests that maintaining the balance of theory and practice through genuine extended school engagement experiences provided opportunities for collaborative connections on multiple levels across the school. This mentoring pathway enhanced and reinforced pre-service teachers’ professional capacity, confidence and employability potential. Limitations such as small sample size and lack of secondary school representation must be noted. Originality/value – This work identified the importance of the unique features of a mentoring programme within a university-school partnership, including the benefits of a full-year immersion experience, financial reward, responsibility, empowerment and enhanced employability status of final year pre-service teachers as they transition to classroom teachers. This paper provides useful insights for researchers, practitioners and teacher education policy developers.

Full text
Abstract:
Abstract Females and males often face different sources of selection, resulting in dimorphism in morphological, physiological, and even cognitive traits. Sex differences are often studied in respect to spatial cognition, yet the different ecological roles of males and females might shape cognition in multiple ways. For example, in dietary generalist bumblebees (Bombus), the ability to learn associations is critical to female workers, who face informationally rich foraging scenarios as they collect nectar and pollen from thousands of flowers over a period of weeks to months to feed the colony. While male bumblebees likely need to learn associations as well, they only forage for themselves while searching for potential mates. It is thus less clear whether foraging males would benefit from the same associative learning performance as foraging females. In this system, as in others, cognitive performance is typically studied in lab-reared animals under captive conditions, which may not be representative of patterns in the wild. In the first test of sex and species differences in cognition using wild bumblebees, we compared the performance of Bombus vancouverensis nearcticus (formerly bifarius) and Bombus vosnesenskii of both sexes on an associative learning task at Sierra Nevada (CA) field sites. Across both species, we found that males and females did not differ in their ability to learn, although males were slower to respond to the sucrose reward. These results offer the first evidence from natural populations that male bumblebees may be equally as able to learn associations as females, supporting findings from captive colonies of commercial bees. The observed interspecific variation in learning ability opens the door to using the Bombus system to test hypotheses about comparative cognition.

Abstract:
Abstract Objectives Gut microbes, including probiotics, can exert a wide range of effects on the host, such as influencing gastrointestinal function and, in some cases, brain function and behavior. Although long-term exposure to certain probiotics have also been shown to alter brain function via vagal communication routes, it is possible that probiotics may influence the brain more acutely, such as shortly after administration. Indeed, gastrointestinal stimuli can activate vagal-dependent brain reward pathways within minutes of induction. Therefore, this study aimed to examine the short-term effects of acute probiotic exposure on neural activity in the brain and gut. Methods CF-1 mice were divided into three groups: probiotic (109 CFUs Enterococcus faecium in 200 ul PBS), gavage control (200 ul PBS), control groups (handling only). These groups were further divided into 3 subgroups to evaluate the temporal effects of acute probiotic administration at 3, 5, and 7 hours after a single dose of probiotic. c-Fos immunohistochemistry was used as a marker of neural activity in multiple regions of the brain and gut suggested to be affected by probiotics. Results Preliminary findings suggest that c-Fos positive cell density in the dentate gyrus of the hippocampus and ventral tegmental area were unaffected by acute administration of E. faecium. Data collection of c-Fos density is underway in other brain areas (i.e., parabrachial nucleus, bed nucleus of the stria terminalis, caudate putamen, pontine nucleus, and solitary nucleus tract) as well as the intestines (i.e., duodenum, jejunum, ileum, cecum, proximal and distal colon). Conclusions While preliminary evidence indicates that the dentate gyrus and ventral tegmental area were unaffected within the initial hours after a single dose of E. faecium, many brain and gut areas remain to be analyzed. Together, these data may collectively provide insight into the immediate effects of probiotics on gut and brain activity.

Abstract:
Background: The high costs of implementing surveys are increasingly leading research teams to either cut back on surveys or to rely on administrative records. Yet no policy should be based on a single set of estimates, and every approach has its weaknesses. A mixture of approaches, each with its own biases, should provide the analyst with a better understanding of the underlying phenomenon. This claim is illustrated with a comparison of employment effect estimates of two conditional cash transfer programs in New York City using survey and administrative unemployment insurance (UI) data. Objectives: This article explores whether using administrative data and survey data produce different impact estimates and investigates the source of differential effects between data sources. Research design: The results of a survey nonresponse bias analysis and an analysis of characteristics of non-UI-covered job characteristics using data collected on 6,000 families who enrolled in either the Family Rewards or Work Rewards evaluation are presented. Results: In both evaluations, survey data showed positive employment effects, while administrative data showed no statistically significant employment effects. Family Rewards increased employment mostly in non-UI-covered jobs, while the positive survey impact estimates in Work Rewards were partially due to survey nonresponse bias. Conclusions: Despite cost pressures leading researchers to collect and analyze only administrative records, the results suggest that survey and administrative records data both suffer from different kinds of sample attrition, and researchers may need to triangulate data sources to draw accurate conclusions about program effects. Developing more economical data collection practices is a major priority.

Additionally, these models did not account for BAS facets encompassing the anticipation of reward, i.e., goal-driven persistence (BAS–GDP) and reward interest (BAS–RI), from those that deal with the actual hedonic experience of reward, i.e., reward reactivity (BAS–RR) and impulsivity (BAS–I). Using resting electroencephalographic (EEG) recordings, the source localization (LORETA) method allowed us to calculate the hemispheric asymmetry of the current density within the alpha band (7.5–13 Hz) in ten regions of interest. Compared to low BAS subtrait scorers, high BAS subtrait scorers (except for BAS–I) were correlated with greater relative left-sided activity in the superior frontal gyrus (BA10). Further, an isolated effective coherence (iCOH) analysis of the beta activity (21 Hz) disclosed that high impulsive scorers as compared to low impulsive ones had higher connectivity between the superior frontal gyrus and middle temporal gyrus, which was not compensated for by enhanced inhibitory alpha (11 Hz) connectivity between these regions. For the beta frequency, we also found in highly impulsive individuals that (i) both left and right middle temporal lobes directly influenced the activity of the left and right superior frontal lobes, and (ii) a clear decoupling between left and right superior frontal lobes. These findings could indicate reduced control by the supervisory system in more impulsive individuals.

Abstract:
Purpose The purpose of this paper is to investigate the extent to which rewards-based crowdfunding really does provide financial support for start-ups and small businesses relative to other types of activity such as creative and cultural projects. Design/methodology/approach The paper reports findings from a series of multiple regression on a unique data set covering around 205,000 rewards-based crowdfunding projects across a number of leading platforms in the USA, the UK and Canada. Findings The authors report two main findings. First, rewards-based crowdfunding is highly inequitably distributed and that success is concentrated within a relatively small number of platforms and campaigns. Second, crowdfunding campaigns explicitly related to business perform relatively poorly compared with those in other categories; particularly those in creative areas such as music and dance. Originality/value These findings call into question the extent to which rewards-based crowdfunding really is a means by which significant numbers of start-ups can bridge gaps in the provision of finance.

Abstract:
Crowdfunding has become a new phenomenon of raising capital for business. Crowdfunding is prevalent in developed nations, while it is just getting popular in developing countries. The research method used for the research was multiple case studies. The purposive sampling method was used to select the five participants for the research. The questionnaire contained fifteen questions. Eighteen themes were generated from the questions. As a result of Social distancing for protection under COVID 19, questions were sent to the respondents via the Google form. The thematic analysis result revealed that agricultural business is the most popular when it comes to crowdfunding. It is an opportunity for entrepreneurs to raise money from another source, easier to access funds through crowdfunding. The crowdfunding approaches used to raise funds by the five participants are loans, hybrid, reward-based, and royalty-based approaches. Crowdfunding is an effective funding alternative for entrepreneurs.

Abstract:
Working life in public sector professions is undergoing significant change and becoming increasingly demanding. This article explores work intensity in NHS ambulance services in England, describing four distinct but interrelated dimensions of intensity: temporal; physical; emotional; and organizational. We use the concept of edgework to explore the complexities involved in how emergency workers attempt to negotiate the rewards and risks associated with multidimensional work intensity. Although certain parts of ambulance work may be intrinsically intense and can provide an important source of validation, organizational elements have the potential to push work intensity to unnecessary extremes. Ambulance services are ‘professionalizing’, but as work in ambulance trusts continues to intensify, issues over dignity, staff retention and the meaning of work are becoming ever more challenging, just as they are in other public service professions.

Abstract:
Purpose – The purpose of this paper is to examine the dilemma that is based on a decision to disclose or not to disclose social shopping rewards (SSRs), in an effort to enhance the effectiveness of social shopping. To protect consumers and guide marketers, emergent forms of online commerce on social media platforms warrant closer examination. One such form is social shopping, which combines social media and online shopping. To motivate word of mouth (WOM) through social signs of approval or endorsement of brands, marketers have typically relied on social shopping rewards (SSRs). It is not typical, however, for the reason behind the social endorsement to be disclosed, leaving the branded message open to multiple interpretations. Design/methodology/approach – The dilemma of SSR disclosures is presented in a marketing and public policy analysis, drawing from findings from the WOM literature on disclosure, incentives, source credibility and on social media Disclosure Guidelines by the Federal Trade Commission (FTC) and Word of Mouth Marketing Association (WOMMA). Based on this analysis and on an extension of the Dual Credibility Model, a conceptual model is proposed that shows how disclosure works through source credibility to produce positive social shopping outcomes. Findings – In addition to the conceptual model, recommendations are made for marketing research, practice and public policy. Of significance are proposed SSR Disclosure Guidelines that extend FTC and WOMMA guidelines for best practices in disclosures in social media. Originality/value – This paper represents pioneering research on the disclosure of SSRs.

Full text
Abstract:
Abstract Motivation Multiple events extraction from biomedical literature is a challenging task for biomedical community. Usually, biomedical event extraction is modeled as two sub-tasks, trigger identification and argument detection. Most existing methods perform these two sub-tasks sequentially, and fail to make full use of the interaction between them, leading to suboptimal results for multiple biomedical events extraction. Results We propose a novel framework of reinforcement learning (RL) for the task of multiple biomedical events extraction. More specifically, trigger identification and argument detection are treated as main-task and subsidiary-task, respectively. Assigning the event type of triggers (in the main-task) is viewed as the action taken in RL, and the result of corresponding argument detection (i.e. the subsidiary-task) for the identified trigger is used for computing the reward of the taken action. Moreover, the result of the subsidiary-task is modeled as part of environment information in RL to help the procedure of trigger identification. In addition, external biomedical knowledge bases are employed for representation learning of biomedical text, which can improve the performance of biomedical event extraction. Results on two widely used biomedical corpora demonstrate that the proposed framework performs better than the selected baselines on the task of multiple events extraction. The ablation test indicates the contributions of RL and external KBs to the performance improvement in the proposed method. In addition, by modeling multiple events extraction under the RL framework, the supervised information is exploited more effectively than the classical supervised learning paradigm.

Abstract:
Cognition arguably drives most behaviours in animals, but whether and why individuals in the wild vary consistently in their cognitive performance is scarcely known, especially under mixed-species scenarios. One reason for this is that quantifying the relative importance of individual, contextual, ecological and social factors remains a major challenge. We examined how many of these factors, and sources of bias, affected participation and performance, in an initial discrimination learning experiment and two reversal learning experiments during self-administered trials in a population of great tits and blue tits. Individuals were randomly allocated to different rewarding feeders within an array. Participation was high and only weakly affected by age and species. In the initial learning experiment, great tits learned faster than blue tits. Great tits also showed greater consistency in performance across two reversal learning experiments. Individuals assigned to the feeders on the edge of the array learned faster. More errors were made on feeders neighbouring the rewarded feeder and on feeders that had been rewarded in the previous experiment. Our estimates of learning consistency were unaffected by multiple factors, suggesting that, even though there was some influence of these factors on performance, we obtained a robust measure of discrimination learning in the wild.

Abstract:
Purpose Policy makers are applying market-inspired competition and financial incentives to drive efficiency in healthcare. However, a lack of knowledge exists about the process whereby incentives are filtered through organizations to influence staff motivation, and the key role of managers is often overlooked. The purpose of this paper is to explore the strategies managers use as intermediaries between financial incentives and the individual motivation of staff. The authors use empirical data from a local case in Swedish specialized care. Design/methodology/approach The authors conducted an exploratory qualitative case study of a patient-choice reform, including financial incentives, in specialized orthopedics in Sweden. In total, 17 interviews were conducted with professionals in managerial positions, representing six healthcare providers. A hypo-deductive, thematic approach was used to analyze the data. Findings The results show that managers applied alignment strategies to make the incentive model motivating for staff. The managers’ strategies are characterized by attempts to align external rewards with professional values based on their contextual and practical knowledge. Managers occasionally overruled the financial logic of the model to safeguard patient needs and expressed an interest in having a closer dialogue with policy makers about improvements. Originality/value Externally imposed incentives do not automatically motivate healthcare staff. Managers in healthcare play key roles as intermediaries by aligning external rewards with professional values. Managers’ multiple perspectives on healthcare practices and professional culture can also be utilized to improve policy and as a source of knowledge in partnership with policy makers.

Abstract:
AbstractIn this article, we collectively explore the significance of engaging with theory in environmental education research. Inspired by Jackson and Mazzei’s (2011) postqualitative research methodology, each researcher provides a short sample of engaging with his/her chosen theoretical concept for one shared data source. Through our three individual theoretical engagements with a short video, we collectively demonstrate that the data may be enacted in different ways, based on the theoretical concept that is engaged. This may potentially actualise multiple different and partial realities of the researched, and by decentring the researcher, this can also rework humanist epistemologies. We suggest that non-researcher-centred and/or non-anthropocentric actualising may contribute to more sustainable relationships in environmental education and its research, not only between the researcher and the researched, but also among the researchers.

IntroductionPatient-held records (PHRs) are proposed to improve communication and coordination of care amongst young people with life-limiting conditions their families and health professionals. However implementation of PHRs has proved difficult due to technical organisational and professional barriers.1AimsTo identify the factors which help or hinder the use of PHRs by young people with life-limiting conditions.MethodSystematic realist review. Literature was sourced from six databases: Medline Embase CINAHL PsychInfo The Cochrane Library Science Direct (from 1946 to December Week 1 2016). The web was searched to identify grey literature. Articles were sourced from reference lists of included studies. Data were extracted using a standardised data extraction form. Two reviewers completed data extraction and synthesis. Methodological rigor was assessed using the relevant Critical Appraisal Skills Programme (CASP) tool.ResultsNine articles were included each reporting on a different PHR. Young people (and/or parents/carers) with conditions of higher severity requiring ongoing care more medications and frequent appointments with multiple providers were more engaged with the PHR. Service providers need sufficient knowledge about the PHR and organisations need to ensure staff can see the benefits of using the PHR for implementation success. Mechanisms triggered by the PHR included improved self-advocacy and young people becoming empowered to self-manage their condition.ConclusionClear definitions of which young people would benefit from using a PHR must be established in order to direct resources accordingly. These definitions will help inform which organisations and service providers would see the most reward from PHR implementation.Reference. Archer N, Fevrier-Thomas U, Lokker C, McKibbon KA, Straus SE.

Full text
Abstract:
The Congo River is the deepest in the world and second-longest in Africa. Harnessing its full hydropower potential has been an ongoing development dream of the Democratic Republic of Congo (DRC) and its more powerful regional allies. If completed, the Grand Inga complex near Kinshasa, the capital of the DRC, will be the largest dam project in the world. Its eight separate dams (Inga 1–8) are envisioned to be “lighting up and powering Africa”. Opponents claim, however, that the rewards will be outsourced to corporate mining interests rather than meeting the needs of the local population, and that the project is flawed economically, socially and environmentally. The planned construction of the Inga dams and associated infrastructure has been stuck in limbo since it was mooted in the 1960s; a fantasy rather than a reality. This article attempts to analyse the rivalry underlying the Grand Inga scheme beyond the “pro” and “contra” reports. Embracing Lacanian psychoanalysis and triangulating multiple sources, we seek to unmask Grand Inga as a potent fantasy. Whilst exhibiting its purpose to serve as a screen to protect both proponents of and opponents to the dam from encountering their own self-deception, we conclude the scheme to be at its most powerful whilst the dream remains unfulfilled.

Abstract:
Dividend payment is one of the rewards given by the company to investors for the time, risk, and commitment of a number of funds that have been given to the company. The distribution of dividends is generally carried out at the end of each financial reporting year and has obtained the approval of the General Meeting of Shareholders (RUPS). However, the distribution of company dividends is not mandatory, the agreement on the deal and certain factors. This study aims to identify the influence of financial factors and corporate governance (institutional ownership and managerial ownership) on company dividend policy. The type of data used in this research is quantitative data, which comes from secondary sources. The method used is purposive sampling with criteria, namely manufacturing companies in the consumer goods sector listed on the Indonesia Stock Exchange for the period 2016-2019. The data analysis technique used in this study is multiple linear regression with SPSS version 26 software. The results of this study indicate that financial factors such as profitability, company size, and company growth have an effect on dividend policy. Meanwhile, liquidity and leverage have no effect on dividend policy. In corporate governance, it is known that managerial ownership and ownership have no effect on dividend policy.

Abstract:
2011 saw the start of the pilot phase of the Social Credit System. The societies of democratic states interpreted it as an extreme example of human rights violation. In turn, what is usually forgotten is that the SCS is not the first citizen assessment system, because similar systems have been successfully functioning since 1960s in democratic countries. Scientific analyses of SCS operations are usually limited to its negative consequences. There are fewer attempts by governments of democratic states to assess the use of elements of SCS and algorithmic data analysis, for example in order to increase the level of security of citizens. As a result, this article presents the research hypothesis that elements of the SCS may be successfully applied also in democratic states for the purpose of more effective combating of terrorism. With modern methods of analyzing Big Data sets, it is possible, for example, to accelerate recognition of terrorist networks, support identification of sources of radicalization in online communities and increase the effectiveness of anti-terrorist strategies in order to protect citizens against contemporary terrorist threats. For such a system to be as effective as possible, it should take over some assumptions of the SCS which are explained in this article: Firstly, it should be centralized and controlled by the state. Secondly, the information obtained and processed should be used solely for the purposes of the state security policy, i.e. in the scope smaller than in the case of China. Thirdly, the data should be obtained from multiple sources, public and private ones, in order to increase the accuracy of predictions. Fourthly, the violation of the principles of social coexistence might result in specific penalties, and compliance therewith – in rewards.

Abstract:
Purpose The purpose of this paper is to compare and integrate leader-member exchange (LMX) and leader identification (LID) as concurrently functioning mediators between three leadership styles (individual-focused transformational, contingent reward, and benevolent paternalistic) and two citizenship behaviors (helping and taking charge). Design/methodology/approach Data included 395 stable, independent leader-follower dyads from numerous Chinese organizations. Partial least squares structural equation modeling and relative weight analysis were used in data analyses. Findings In established, steady-state leader-member alliances, LMX was the dominant explanation between various leadership styles and helping; whereas LID explained leadership effects on taking charge. Three-stage indirect effects of leadership-LMX-LID-taking charge were found. Also, LMX and LID related to the three focal leadership styles in distinct ways. Research limitations/implications Limitations include cross-sectional data. Strengths include a large, multi-source field sample. Implications include that LMX and LID provide different prosocial motivations; LMX indirectly engenders stronger other-orientation through LID; and the nature of indirect leadership effects via LID is more sensitive to the nature of the focal leadership styles. LMX and LID together provide a package of prosocial motivations. Practical implications Leaders interested in increasing employees’ helping vs taking charge behaviors can be more effective by understanding the different motivational potentials of LMX vs LID. Leaders also need to choose appropriate behavioral styles when they activate LMX vis-à-vis LID. Originality/value This study integrates multiple leadership theories to provide a nuanced account of how social exchange and self-concept explain leadership at the interpersonal level when leadership styles, LMX, and LID are stable.

Abstract:
Cholinergic neurons in the laterodorsal tegmental (LDT) and peduncolopontine tegmental (PPT) nuclei regulate reward, arousal, and sensory gating via major projections to midbrain dopamine regions, the thalamus, and pontine targets. Muscarinic acetylcholine receptors (mAChRs) on LDT neurons produce a membrane hyperpolarization and inhibit spike-evoked Ca2+ transients. Pharmacological studies suggest M2 mAChRs are involved, but the role of these and other localized mAChRs (M1--M4) has not been definitively tested. To identify the underlying receptors and to circumvent the limited receptor selectivity of available mAChR ligands, we used light- and electron-immunomicroscopy and whole cell recording with Ca2+ imaging in brain slices from knockout mice constitutively lacking either M2, M4, or both mAChRs. Immunomicroscopy findings support a role for M2 mAChRs, since cholinergic and noncholinergic LDT and pedunculopontine tegmental neurons contain M2-specific immunoreactivity. However, whole cell recording revealed that the presence of either M2 or M4 mAChRs was sufficient, and that the presence of at least one of these receptors was required for these carbachol actions. Moreover, in the absence of M2 and M4 mAChRs, carbachol elicited both direct excitation and barrages of spontaneous excitatory postsynaptic potentials (sEPSPs) in cholinergic LDT neurons mediated by M1 and/or M3 mAChRs. Focal carbachol application to surgically reduced slices suggest that local glutamatergic neurons are a source of these sEPSPs. Finally, neither direct nor indirect excitation were knockout artifacts, since each was detected in wild-type slices, although sEPSP barrages were delayed, suggesting M2 and M4 receptors normally delay excitation of glutamatergic inputs. Collectively, our findings indicate that multiple mAChRs coordinate cholinergic outflow from the LDT in an unexpectedly complex manner. An intriguing possibility is that a local circuit transforms LDT muscarinic inputs from a negative feedback signal for transient inputs into positive feedback for persistent inputs to facilitate different firing patterns across behavioral states.

Abstract:
Purpose The purpose of this paper is to review the literature on UK older people’s forums. Forums seek to influence statutory responses to ageing, and enable older people to speak up on matters important to them. The review examined three facets of forums: their membership, structures, and effectiveness. Design/methodology/approach Methods included searching databases, internet, and specialist libraries for materials relating to older people’s forums. Key points were extracted and source material described but not subject to quality appraisal. Relevant non-UK studies are included to draw contrast and comparisons. Findings Several studies and reports have explored forum members’ socio-demographic profiles, motivations and triggers for joining and the two-way rewards of participation. However, membership remains a minority activity, with only a small percentage of members actively engaged and the review highlights gaps in the literature on widening participation. Both statutory and voluntary sectors have supported forum development and sustainability. There is little data on formal structures but some exploration of the informal communications and behaviours that sustain them has been undertaken. Forums are viewed as effective but resource intensive. The size and representativeness of the membership, strength of influence and deployment of members’ expertise are all identified as potential contributors to effectiveness. Research limitations/implications Some material may not have been accessible and there is potential bias by greater inclusion of journal published materials than other possible sources. Material was not quality appraised, and research literature and self-reporting by forums are presented alongside each other. Practical implications Practitioners should familiarise themselves with current older people’s organisations locally to ensure that consultations are broad and reach different groups. While partnerships with voluntary sector health and care providers are encouraged some of these groups may not wish to represent all older people. Wider reach may provide multiple perspectives. Help in kind as well as financial resources may be welcomed by older people’s groups, such as meeting spaces, assistance with administration, and briefings that are accessible. Offering to meet with older people’s forums to discuss matters regularly may provide insight into experiences of services and changing needs earlier than professional feedback. Dismissing older people’s forums as made up of the “usual suspects” is likely to be unfair and unhelpful to building up positive relationships. Originality/value The review provides a preliminary assessment of the size and scope of research and grey literature on UK older people’s forums, synthesising points of similarity and difference and identifying clear gaps in the evidence.

Abstract:
Purpose The purpose of this paper is to focus on the enterprise lending and control process in closely held banks, with special reference to Sri Lanka. It explores how those processes are being influenced by the distinctive cultural and political processes at organizational and societal levels. Design/methodology/approach The study relies on three cases built upon the life experiences of several employees in a closely held bank, articulating multiple sources of evidence: interviews, observations, documents, archival records, open-ended questionnaires, internet conversations and exchange of e-mails. The data analysis adopts cultural political economy theory. Findings The study’s findings reveal how cultural and political factors, such as egoistic motives and politics, gifts/rewards and a manipulative culture, along with exploitative and discriminatory politics at organizational and societal levels, articulate into the enterprise lending and control process (“five Cs”) in closely held banks. “Rational” enterprise lending and control processes in this context merely become a “ceremonial” practice, serving the petty interest of powerful capitalist business owners. Whereas previous studies emphasize that the criteria (five Cs) discriminate against ordinary people, as distinct from the élite, the findings of this study implicate that over and above that the criteria are set aside when it suits in order to favor or accommodate the élite. Originality/value The paper provides a “qualitative inquiry” on how cultural politics at organizational and societal-level effect on enterprise lending and control process within closely held banks in less developed countries (LDCs). The previous studies on bank lending and control used either large-scale surveys or alternatively devoted their interest toward the role and impact of accounting in World Bank and IMF-led lending schemes and policies, particularly in LDCs.

Full text
Abstract:
The three papers by Elisheva Carlebach, David Sorkin, and Adam Teller refreshingly do not merely invoke the name of Salo Baron as a sacred authority but actually reflect critically upon significant pieces of his scholarly corpus. As Adam Teller has pointed out correctly, academic historians of the Jews have sought for decades to align themselves with what they have taken to be the fundamental thrust of Baron's approach to his subject and have warned their students against too great a deviation from it. In the discourse of the field, to claim Baron's mantel is altogether bon ton, while “lachrymose” has long served as a term of severe reproach. Yet, many more people appear to have claimed to be Baron's acolytes in abjuring lachrymosity than have actually read a significant portion of Baron's corpus, much less seriously engaged with what he had to say in those writings. The three contributors are, happily, not among them: in their papers they all have entered into a genuine conversation with certain key propositions in Baron's work, with a mind to refining his insights and building upon them. Baron has served them not as an icon but as an interlocutor in the continuing discussion of significant problems to which he devoted much thought and study. That is a salutary development. Baron's contribution to the study of Jewish history was hardly exhausted by his articulation of a particular conceptual approach to it. As anyone who takes the multiple volumes of A Social and Religious History of the Jews or The Jewish Community in hand becomes aware immediately, Baron was a prodigious researcher whose painstaking mining (and in some cases even discovery) of a vast array of source materials laid the empirical foundations for future scholarship on a broad range of Jewish historical subjects. On that level, as well, reading his work returns significant rewards.

Abstract:
Purpose Institutional work mainly focused on the purposive action of rational actors. However, the evolution of institution is not only affected by deliberate actions but also by emergent strategic patterns. Through a qualitative study of emergent aggression strategy in a Chinese leading private firm, Gome, this paper aims to explore the role of emergent strategy in institutional work. The paper finds that emergent strategy influences the normative and cognitive institution unconsciously and offers actors specialized identities. The present analysis also suggests that the emergent strategy-based institution needs a supporting and repairing system for maintenance. Design/methodology/approach This study primarily considers the micro aspect of emergent strategy and institutional work. It calls for detailed observation, interviews and archival materials which can make up a comprehensive in-depth picture. The authors remain skeptical to what people claim and try to get multiple sources of information. Also, the topic the authors deal with is relatively under-researched, and it is valuable to get explorative richness. Therefore, an interpretive qualitative approach is adopted to investigate actual events from “the native’s” perspective. Findings We found that an emergent strategy, which is realized but without previous plans, can also construct a “proto-type institution”, only in an unconscious way. The precondition is that the strategic resources of the focal firm are abundant enough for it to set the criteria of inter-organizational sanctions and rewards. In addition, the authors believe that supportive system and repairing system underpin the maintenance of established institutions. Originality/value First, by combining the research on emergent strategy to institutional work, the authors extend the scope of the latter by adding unconscious institutional work. Even if the agent-based view is adopted, rational actors can still influence the institution. Second, the authors explored the institutional outcome of emergent strategy, which fills the paucity of strategy process research. Third, aggression, the specific emergent strategy in this paper, can be turned into “plans for the future”. Its prevalence in the emerging market will attract more academic attention.

Abstract:
Purpose Indonesia was chosen to be a site of study on leadership style due to its high economic growth potential. The primary objectives of this study are twofold. This paper aims to, first, explore the leadership styles of Indonesian managers and investigate whether the full range leadership theory by Bass (1985), i.e. transformational, transactional and laissez-faire leadership, is applicable in the Indonesian context and second, investigate whether there are differences in leadership styles among Indonesian managers, as Indonesian people are composed of over 300 ethnicities. Design/methodology/approach Respondents were asked to rate their direct bosses on leadership and their perceived performance on an multifactor leadership questionnaire. In all, 425 Indonesian managers participated in the study. Multiple regression and t-test were used to address the above research questions. Findings Results indicated that the full range leadership theory is applicable in the Indonesian context, in which Indonesian people generally rate their superiors who use transformational leadership higher than those who use transactional and laissez-faire leadership. Ethnic differences in leadership style were found between that of Padang and Javanese and of Padang and Chinese. Padang managers, whose cultural values are quite unique, seem to practice more transformational leadership and contingent reward, which is a positive reinforcement in transactional leadership. Research limitations/implications Common method bias may occur due to the single source of data, i.e. subordinates. The confidentiality of the survey helps reduce the bias as subordinates could evaluate their bosses in a true manner. In addition, categorizing ethnicities among Indonesians is not an easy task. A finer distinction of ethnicities is certainly needed in future research. Practical implications The results are useful for human resource department in selecting the potential leaders, as transformational leaders are generally more preferable. In addition, the findings shed some light on the effective leadership styles of Indonesian managers perceived by their subordinates. Originality/value One major theoretical contribution of this study is a proof of the applicability of the full range leadership theory by Bass (1985) in Indonesian work setting. It confirms the extension of the theory’s universality. A unique theoretical contribution of this study is its being the first study that addresses the ethnic differences in leadership style in Indonesia.

Abstract:
Employees are major assets of any organization. The active role they play towards a company’s success cannot be underestimated. As a result, equipping these unique assets through effective training becomes imperative in order to maximize the job performance. Despite the fact that training and development is well planned and systematic in the ministry of labour and social protection it still have issues of employees still not performing up to standard operating procedure in the work environment and labour turn over. Therefore, this study sought to determine the influence of training and development techniques on the performance of employees in the Ministry of labour and social protection. This study was guided by the following specific research objectives; to examine the influence of coaching, job rotation, role playing and apprenticeship on employee performance in the ministry of labour and social protection. This study was guided by goal setting theory and social exchange theory. The study used a descriptive design. The target population was 60 respondents comprising of 5 HRM managers and 10 supervisors and 45 Support staff. A census of 60 respondents was carried out. The study used questionnaires for the support staff and interviews for the HRM managers and supervisors. The qualitative data collected from the interviews was analysed using content analysis. Quantitative data was analyzed using descriptive statistics such as mean and standard deviation and presented using charts, figures, table and graphs. The study conducted a multiple regression analysis to test the relationship between independent variables and dependent variable. The study examined that coaching, job rotation, role playing and apprenticeship had a positive significant influence on employee performance. The study concludes that Coaching positively impacted employees careers as well as their lives by helping them to establish and take action towards achieving goals, Job rotation increased job satisfaction because employees were exposed to various work tasks that reduced constant physical or mental stress, which could create more motivation to continue in the position and reduce turnover, role playing brought together employees and or created a positive relationship among the employees in the work environment and apprenticeships are structured training programmes offered by the Ministry which gives their trainees a chance to work towards a qualification and offers them a vast experience that enable them to work elsewhere. The study recommends that The Ministry should devise clear goals that include benchmarks and deadlines, be prepared to help with time management, frame feedback in a forthright and positive manner, follow up on feedback, emphasize effort over ability and celebrate accomplishments. The Ministry should determine the critical positions or functions to include in the program, conduct a job analysis to determine the components of the job that are most important to learn during the job rotation, determine the ideal bench strength for each role, create job readiness assessments and an evaluation process, orient the employees, measure and reward success. The Ministry should identify the objective, need, experience of trainee, the issue or task for which role play method is selected. The focus should be on maximum involvement of individuals as participants so that an overall exposure and that The Ministry should have apprenticeship programs in every section which is in line the current needs of the organization and which comply with the ever changing organizational environment.

Abstract:
Anthropogenic global warming (AGW) heat is trapped by the greenhouse gas (GHG) blanket, and the ocean surface layer. It is 93% in the ocean and drives atmospheric warming. The 111-year mean daily surface temperatures are 10.5±0.5°C at Port Erin (PE) Isle of Man compared with 9.6±4.8°C in Central England (CET) air. The Port Erin 5½-year max-min heat cycle synchronizes to the 11-year solar heat pump sunspot cycle. Tropical heat arrives 2 years after a solar maximum on wind-driven currents in the stratified sea surface. Runoff from bottom-up melted Arctic icesheets arrives 3½ year later at solar minimum. These warm and cold waters are the biodiversity source. PE is unique with seasonal meltwaters of Pacific and Atlantic origin. The North Pacific warms twice as fast as other oceans. All ocean near-surface gyre currents harmonize with sunspot cycles. Net cooling by polar icemelt masks catastrophic exponential ocean warming and icemelt. Eleven counter-rotating surface gyres carry heat and nutrients globally in verified ocean surface circulation system.Exponential growth is unsustainable in a finite system. It trends to infinity. Double-exponential gets there twice as quickly. The GHG blanket, grown double-exponentially for 250 years, is now in control. Ocean heat absorption takes 150-250 years. Arctic icemelt increases double-exponentially. The Arctic long-term annual freeze-melt volume cycle is 16.8±1.3 thousand cubic km per year. Polar land icemelt adds ~500 km3 per year. Freeze-brine of salinity >40‰ and temperature –1°C, sinks to the bottom. Equatorial evaporative-brine of salinity >36.4‰ and >28°C floats subsurface under fresh warm layers thickening westwards in tropical meridional cells to ~75m depth. This is consistent with observed extreme weather.Heat imbalance forced Pacific Ocean temperatures above proposed limits of +2°C in 1993, to +3°C in 2014, and is on track for +4°C for 2016. Century-long daily records confirm processes ongoing for 300 years. Coast locations are where impacts are felt and real-time data collected. Corporate governance degraded physics teaching in only 60 years. Individual discovery and data collection was lost. Big science is unnecessary. Satellites cannot do plankton tows. Computer models are governed by the rule of ‘garbage-in garbage-out’. They must be verified by in situ data that cannot be collected retrospectively. Continuous timeseries surface profile data from fixed ocean station locations on a global variable-boundary network are essential. Scientists, if well-trained in ocean experimental physics, can do the hard work.Time-poor scientists, stripped of their intellectual property rights, under rewarded, poorly educated, and ruthlessly exploited by growth-obsessed commercial interests, missed catastrophic global warming and multiple extreme consequences. Climate scientists abandoned classical physics and Newton-Hooke field verification in favor of unverified beliefs, models, and apps. Climate studies confuse heat with temperature, do not include basal icemelt, density temperature-salinity function, Clausius-Clapeyron evaporation exponential skin temperature function, asymmetric brine-heat sequestration, solar and tidal pumping, infra-red GHG heat trap, vertical tropical cells, freshwater warm pools; or wind-driven surface currents at 3 percent of windspeed. Climate model mistaken assumptions lead to the absurd conclusion that evaporation in the Labrador Sea at midnight in midwinter is greater than at the midday Equator.The Isle of Man provides an ideal location for continued monitoring and mitigation research, teaching and public service in a dedicated non-commercial independent multidisciplinary university-type setting. Quality teaching is the major priority. Commercial monopoly rights need replacement with free, fully open discussions and publications. Quality not quantity should be paramount. Internationally competitive academics should control subservient lower paid support staff.Every day without ocean surface data means vital scientific truth lost of interest and concern to all populations. Predictions are groundless without accurate continuous ocean surface data. Skeptics, politicians, statisticians, those with stakes in the status quo, and established research censors obstructing scientific progress squabble in ignorance while the globe burns.

Abstract:
Introduction Researchers around the globe are utilizing crowdsourcing tools to reach respondents for quantitative and qualitative research (Chambers & Nimon, 2019). Many social science and business journals are receiving studies that utilize crowdsourcing tools such as Amazon Mechanical Turk (MTurk), Qualtrics, MicroWorkers, ShortTask, ClickWorker, and Crowdsource (e.g., Ahn, & Back, 2019; Ali et al., 2021; Esfahani, & Ozturk, 2019; Jeong, & Lee, 2017; Zhang et al., 2017). Even though the use of these tools presents a great opportunity for sharing large quantities of data quickly, some challenges must also be addressed. The purpose of this guide is to present the basic ideas behind the use of crowdsourcing for survey research and provide a primer for best practices that will increase their validity and reliability. What is crowdsourcing research? Crowdsourcing describes the collection of information, opinions, or other types of input from a large number of people, typically via the internet, and which may or may not receive (financial) compensation (Hargrave, 2019; Oxford Dictionary, n.d.). Within the behavioral science realm, crowdsourcing is defined as the use of internet services for hosting research activities and for creating opportunities for a large population of participants. Applications of crowdsourcing techniques have evolved over the decades, establishing the strong informational power of crowds. The advent of Web 2.0 has expanded the possibilities of crowdsourcing, with new online tools such as online reviews, forums, Wikipedia, Qualtrics, or MTurk, but also other platforms such as Crowdflower and Prolific Academic (Peer et al., 2017; Sheehan, 2018). Crowdsourcing platforms in the age of Web 2.0 use remote labor recruited via the internet to assist employers complete tasks that cannot be left to machines. Key characteristics of crowdsourcing include payment for workers, their recruitment from any location, and the completion of tasks (Behrend et al., 2011). They also allow for a relatively quick collection of data compared to data collection in the field, and participants are rewarded with an incentive—often financial compensation. Crowdsourcing not only offers a large participation pool but also a streamlined process for the study design, participant recruitment, and data collection as well as integrated participant compensation system (Buhrmester et al., 2011). Also, compared to other traditional marketing firms, crowdsourcing makes it easier to detect possible sampling biases (Garrow et al., 2020). Due to advantages such as reduced costs, diversity of participants, and flexibility, crowdsourcing platforms have surged in popularity for researchers. Advantages MTurk is one of the most popular crowdsourcing platforms among researchers, allowing Requesters to submit tasks for Workers to complete (Cummings & Sibona, 2017). MTurk has been used as an online crowdsourcing platform for the recruitment of human subjects for research purposes (Paolacci & Chandler, 2014). Research has also shown MTurk to be a reliable and cost-effective tool, capable of providing representative data for research in the behavioral sciences (e.g., Crump et al., 2013; Goodman et al., 2013; Mason & Suri, 2012; Rand, 2012; Simcox & Fiez, 2014). In addition to its use in social science studies, the platform has been used in marketing, hospitality and tourism, psychology, political science, communication, and sociology contexts (Sheehan, 2018). To illustrate, between 2012 and 2017, more than 40% of the studies published in the Journal of Consumer Research used crowdsourcing websites for their data collection (Goodman & Paolacci, 2017). Disadvantages Although researchers have assessed crowdsourcing platforms as reliable and cost-effective for data collection in the behavioral sciences, they are not exempt of flaws. One disadvantage is the possibility of unsatisfactory data quality. In fact, the virtual setting of the survey implies that the investigator is physically separated from the participant, and this lack of monitoring could lead to data quality issues (Sheehan, 2018). In addition, participants in survey research on crowdsourcing platforms are not always who they claim to be, creating issues of trust with the data provided and, ultimately, the quality of the research findings (McGonagle, 2015; Smith et al., 2016). A recurrent concern with MTurk workers, for instance, is their assessment as experienced survey takers (Chandler et al., 2015). This experience is mainly acquired through completion of dozens of surveys per day, especially when they are faced with similar items and scales. Smith et al. (2016) identified two types of problems performing data collection using MTurk; namely, cheaters and speeders. As compared to Qualtrics—which has a strict screening and quality-control processes to ensure that participants are who they claim to be—MTurk appears to be less exigent regarding the workers. However, a downside for data collection with Qualtrics is more expensive fees—about $5.00 per questionnaire on Qualtrics, against $0.50 to $1.50 on MTurk (Ford, 2017). Hence, few researchers were able to conduct surveys and compare respondent pools with Qualtrics or other traditional marketing research firms (Garrow et al., 2020). Another challenge using MTurk arises when trying to collect a desired number of responses from a population targeted to a specific city or area (Ross et al., 2010). The issues inherent to the selection process of MTurk have been the subject of investigations in several studies (e.g., Berinsky et al., 2012; Chandler et al., 2014; 2015; Harms & DeSimone, 2015; Paolacci et al., 2010; Rand, 2012). Feitosa et al. (2015) pointed out that international respondents may still identify themselves as U.S. respondents with the use of fake addresses and accounts. They found that 5% to 10% of participants identifying themselves as U.S. respondents were actually from overseas locations. Moreover, Babin et al. (2016) assessed that the use of trap questions allowed researchers to uncover that many respondents change their genders, ages, careers, or income within the course of a single survey. The issues of (a) experienced workers for the quality control of questions and (b) speeders, which, for MTurk can be attributed to the platform being the main source of revenue for a given respondent, remain the inherent issues of crowdsourcing platforms used for research purposes. Best practices Some best practices can be recommended in the use of crowdsourcing platforms for data collection purposes. Workers IDs can be matched with IDs from previous studies, thus allowing researchers to exclude responses from workers who had answered previous similar studies (Goodman & Paolacci, 2017). Furthermore, proceed to a manual assignment of qualification on MTurk prior to data collection (Litman et al., 2015; Park & Park, 2020). When dealing with experienced workers, both using multiple attention checks and optimizing the survey in a way to have the participants exposed to the stimuli for a sufficient length of time to better address the questions are also recommended (Sheehan, 2018). In this sense, shorter surveys are preferred to longer ones, which affect the participant’s concentration, and may, in turn, adversely impact the quality of their answers. Most importantly, pretest the survey to make sure that all parts are working as expected. Researchers should also keep in mind that in the context of MTurk, the primary method for measurement is the web interface. Thus, to avoid method biases, researchers should ponder whether or not method factors emerge in the latent measurement models (Podsakoff et al., 2012). As such, time-lagged research designs may be preferred as predictor and criterion variables can be measured at different points in time or administered in different platforms, such as Qualtrics vs MTurk (Cheung et al., 2017). In general, the use of crowdsourcing platforms including MTurk may be appropriate according to the research question; and the quality of data is reliant on the quality-control strategies used by researchers to enhance data quality. Trade-offs between various validity types need to be prioritized according to the research objectives (Cheung et al., 2017). From our experience using crowdsourcing tools for our own research as the editorial team members of several journals and chair of several conferences, we provide the best practices as outlined below: MTurk Worker (Respondent) Selection: Researchers should consider their study population before using MTurk for data collection. The MTurk platform should be used for the appropriate study population. For example, if the study targets restaurant owners or company CEOs, MTurk workers may not be suitable for the study. However, if the target population is diners, hotel guests, grocery shoppers, online shoppers, students, or hourly employees, utilizing a sample from MTurk would be suitable. Researchers should use the selection tool in the software. For example, if you target workers only from one country, exclude responses that came from an internet protocol (IP) address outside the targeted country and report the results in the method section. Researchers should consider the demographics of workers on MTurk which must reflect the study targeted population. For example, if the study focuses on baby boomers use of technology, then the MTurk sample should include only baby boomers. Similarly, the gender balance, racial composition, and income of people on MTurk should mirror the targeted population. Researchers should use multiple screening tools that identify quality respondents and avoid problematic response patterns. For example, MTurk provides the approval rate for the respondents. This refers to how many times a respondent is rejected for various reasons (i.e., wrong code entered). We recommend using a 90% or higher approval rate. Researchers should include screening questions in different places with different type of questions to make sure that the respondents are appropriate for your study. One way is to use knowledge-based questions about the subject. For example, rather than asking “How experienced are you with accounting practices?”, a supplemental question such as “Which of the following is a component of an income statement?” should be integrated into the study in a different section of the survey. Survey Validity: Researchers should conduct a pilot survey from MTurk workers to identify and fix any potential data quality and programming problems before the entire data set is collected. Researcher can estimate time required to complete the survey from the pilot study. This average time should be used in calculating incentive payment for the workers in such a way that the payment should equate or exceed minimum wage in the targeted country. Researchers should build multiple validity-check tools into the survey. One of them is to ask attention check questions such as “please click on ‘strongly agree’ in this question” or “What is 2+2? Please choose 5” (Cobanoglu et al., 2016) Even though these attention questions are good and should be implemented, experienced survey takers or bots easily identify them and answer them correctly, but then give random answers to other questions. Instead, we recommend building in more involved validity check questions. One of the best is asking the same question in different places and in different forms. For example, asking the age of the respondent in the beginning of the survey and then asking them the year of their birth at the end of the survey is an effective way to check that they are replying to the survey honestly. Exclude all those who answered the same question differently. Report the results of these validity checks in the methodology. Cavusoglu (2019) found that almost 20% of the surveys were eliminated due to the failure of the validity check questions which were embedded in different places and in different forms in his survey. Researchers should be aware of internet bot, which is a software that runs automated tasks. Some respondents use a bot to reply to the surveys. To avoid this, use Captcha verification, which forces respondents to perform random tasks such as moving the bar to a certain area, clicking in boxes that has cars, or checking boxes to verify the person taking the survey is not a bot. Whenever appropriate, researchers should use time limit options offered by online survey tools such as Qualtrics to control the time that a survey taker must spend to advance to the next question. We found that this is a great tool, especially when you want the respondents to watch a video, read a scenario, or look at a picture before they respond to other questions. Researchers should collect data in different days and times during the week to collect a more diverse and representative sample. Data Cleaning: Researchers should be aware that some respondents do not read questions. They simply select random answers or type nonsense text. To exclude them from the study, manually inspect the data. Exclude anyone who filled out the survey too quickly. We recommend excluding all responses filled out less than 40% of the average time to take the survey. For example, if it takes 10 minutes to fill out a survey, we exclude everyone who fills out this survey in 4 minutes or less. After we separated these two groups, we compared them and found that the speeders’ (aka cheaters) data was significantly different than the regular group. Researchers should always collect more data than needed. Our rule of thumb is to collect 30% more data than needed. For example, if 500 clean data responses are wanted, collect at least 650 data. The targeted number of data will still be available after cleaning the data. Report the process of cleaning data in the method section of your article, showing the editor and reviewers that you have taken steps to increase the validity and reliability of the survey responses. Calculating a response rate for the samples using MTurk is not possible. However, it is possible to calculate active response rate (Ali et al., 2021). It can be calculated as the raw response numbers deducted from all screening and validity check question results. For example, if you have 1000 raw responses and you eliminated 100 responses for coming from IP address outside of the United States, another 100 surveys for failing the validity check questions, then your active response rate would be 800/1000= 80%.

Abstract:
Reward functions are a common way to specify the objective of a robot. As designing reward functions can be extremely challenging, a more promising approach is to directly learn reward functions from human teachers. Importantly, data from human teachers can be collected either passively or actively in a variety of forms: passive data sources include demonstrations (e.g., kinesthetic guidance), whereas preferences (e.g., comparative rankings) are actively elicited. Prior research has independently applied reward learning to these different data sources. However, there exist many domains where multiple sources are complementary and expressive. Motivated by this general problem, we present a framework to integrate multiple sources of information, which are either passively or actively collected from human users. In particular, we present an algorithm that first utilizes user demonstrations to initialize a belief about the reward function, and then actively probes the user with preference queries to zero-in on their true reward. This algorithm not only enables us combine multiple data sources, but it also informs the robot when it should leverage each type of information. Further, our approach accounts for the human’s ability to provide data: yielding user-friendly preference queries which are also theoretically optimal. Our extensive simulated experiments and user studies on a Fetch mobile manipulator demonstrate the superiority and the usability of our integrated framework.

Abstract:
Our decisions often balance what we observe and what we desire. A prime candidate for implementing this complex balancing act is the basal ganglia pathway, but its roles have not yet been examined experimentally in detail. Here, we show that a major input station of the basal ganglia, the caudate nucleus, plays a causal role in integrating uncertain visual evidence and reward context to guide adaptive decision-making. In monkeys making saccadic decisions based on motion cues and asymmetric reward-choice associations, single caudate neurons encoded both sources of information. Electrical microstimulation at caudate sites during motion viewing affected the monkeys’ decisions. These microstimulation effects included coordinated changes in multiple computational components of the decision process that mimicked the monkeys’ similarly coordinated voluntary strategies for balancing visual and reward information. These results imply that the caudate nucleus plays causal roles in coordinating decision processes that balance external evidence and internal preferences.

Abstract Objectives mHealth tools may support dietary management of type 2 diabetes. However, sustaining user engagement is a challenge. We used mixed methods to explore usage of a motivationally tailored custom smartphone application. Methods Platano is a self-determination theory-based app that promotes self-tracking of diet and blood glucose in diabetes. The app has four different interfaces that are tailored to users’ level of extrinsic or intrinsic motivation: monetary reward, registered dietitian feedback on diet goal(s), self-assessment of diet goal(s), or post-meal blood glucose forecast. For PI-TECH, Platano is being evaluated in a pilot Sequential Multiple Assignment Randomized Trial (SMART): participants are sequentially randomized to receive interfaces that match or do not match their level of motivation based on the Treatment Self-Regulation Questionnaire. Here, we report on preliminary results from the initial subset of participants (n = 16, mean age = 54+/−8, 82% female, 94% non-white, 69% household income < $20,000). We retrieved app usage data from logs and conducted in-depth interviews in English with 9 participants after they used Platano for 6 weeks, using Thematic Analysis to identify emerging themes. We generated visualizations that described usage (meals recorded/day) for each participant by app interface. Then we compared emergent themes between intrinsically and extrinsically motivated participants. Results Initial results indicate intrinsically motivated participants (n = 6) logged meals more consistently than extrinsically motivated participants (n = 10); however, extrinsically motivated participants’ usage tended to increase when receiving a monetary reward for logging (figure). While both intrinsically and extrinsically motivated participants described barriers to logging meals and to changing their diet based on insights, intrinsically motivated participants described the value of integrating Platano into their daily routines as outweighing barriers, thus promoting more consistent use. Conclusions Findings suggest that app users’ intrinsic/extrinsic motivation may influence engagement with mHealth tools and diabetes self-management, and tailoring may support engagement. Future analyses will test differences in usage and diet with different app interfaces. Funding Sources Robert Wood Johnson Foundation; NIH NLM T15. Supporting Tables, Images and/or Graphs

Abstract:
Abstract Decentralized policies for information gathering are required when multiple autonomous agents are deployed to collect data about a phenomenon of interest when constant communication cannot be assumed. This is common in tasks involving information gathering with multiple independently operating sensor devices that may operate over large physical distances, such as unmanned aerial vehicles, or in communication limited environments such as in the case of autonomous underwater vehicles. In this paper, we frame the information gathering task as a general decentralized partially observable Markov decision process (Dec-POMDP). The Dec-POMDP is a principled model for co-operative decentralized multi-agent decision-making. An optimal solution of a Dec-POMDP is a set of local policies, one for each agent, which maximizes the expected sum of rewards over time. In contrast to most prior work on Dec-POMDPs, we set the reward as a non-linear function of the agents’ state information, for example the negative Shannon entropy. We argue that such reward functions are well-suited for decentralized information gathering problems. We prove that if the reward function is convex, then the finite-horizon value function of the Dec-POMDP is also convex. We propose the first heuristic anytime algorithm for information gathering Dec-POMDPs, and empirically prove its effectiveness by solving discrete problems an order of magnitude larger than previous state-of-the-art. We also propose an extension to continuous-state problems with finite action and observation spaces by employing particle filtering. The effectiveness of the proposed algorithms is verified in domains such as decentralized target tracking, scientific survey planning, and signal source localization.

Abstract:
PurposeThe purpose of this research is to explore the structure and impact of police officers' social support network on health and well-being. Social integration promotes opportunities for regular positive experiences and a set of stable, socially rewarded roles within one's work and life domains. Identifying the structure and impact areas of police officers' social support network provide guidance for initiatives in improving psychological health for the department and individual officers.Design/methodology/approachSurvey of 162 police officers' sources of support provided a holistic representation of their social network across seven sources. Principle component analyses were conducted to explore the structure of one's social network. Multiple regression analyses were conducted to examine overall impact of one's social support network and relative contributions of support sources in terms of increased well-being and reduced strain.FindingsA three-component structure of social support was partially supported. Overall models of the impact of one's social support network related to increased well-being and reduced strain was supported. Relative contributions of support sources show different patterns based on outcome of interest.Practical implicationsProvides guidance for addressing the psychological well-being needs for officers holistically. In other words, treating officers as whole beings, whose system of support and psychological health is integrated, not piecemeal.Originality/valueExamination of principle effects of support provides a parsimonious approach to considering the holistic value of one's support system, apart from specific stressors or conditions.

Abstract:
Rupert Goold’s screen production of Macbeth – firstly, staged in 2007 and, later, filmed in 2010 – has been studied as an example of the stage-to-screen hybrid corpus of Shakespearean audio-visual adaptations. Thus, much of the critical emphasis on the production has been placed on its filmic qualities. Particularly, the genre film conventions deployed across the film has summoned the attention of Shakespeare on screen scholars and it has been the creators’ intentions to precisely point at Goold’s filmic intertextual repertoire. Given the recent increasing attention to the multiple media and languages employed in stage-to-screen hybrid Shakespearean adaptations and other exchanges between the languages of the stage and film to rework Shakespearean and theatrical productions, it is instructive to observe the ways in which adaptations such as this one engage with larger processes of transmedia storytelling, not only paying attention to theatrical and filmic languages but to the transmedia strategies these TV theatrical films make use of. Importantly, it is instructive to look into the narrative and philosophical purposes served by transmedia storytelling as the multiple media and languages used in the film display a range of temporalities and film genres associated to them that allow us to expand the interpretive range of Shakespeare’s source text. Following this premise, this essay examines Goold’s Macbeth as a nostalgia narrative in which transmedia strategies serve to display a range of media-based narrative strands that expand the film’s range of possible interpretations. To prove this, I will insert Goold’s film in the larger process of transmedia storytelling encompassing the performance history of Macbeth. Additionally, I will identify narrative strands in Goold’s televisual, theatrical, musical, poetic and computer-based sources. The results will show that Macbeth – and, by extension, potentially this applies to TV theatrical adaptations of Shakespeare’s plays – constitutes a strand of the larger corpus of transmedia storytelling wrapping up the Scottish play’s performance history as well as Shakespeare’s overall performance history.

Abstract:
Abstract Here we describe the development and application of miniature integrated microscopes (miniscopes) paired with microendoscopes that allow for the visualization and manipulation of neural circuits in superficial and subcortical brain regions in freely behaving animals. Over the past decade the miniscope platform has expanded to include simultaneous optogenetic capabilities, electrically-tunable lenses that enable multi-plane imaging, color-corrected optics, and an integrated data acquisition platform that streamlines multimodal experiments. Miniscopes have given researchers an unprecedented ability to monitor hundreds to thousands of genetically-defined neurons from weeks to months in both healthy and diseased animal brains. Sophisticated algorithms that take advantage of constrained matrix factorization allow for background estimation and reliable cell identification, greatly improving the reliability and scalability of source extraction for large imaging datasets. Data generated from miniscopes have empowered researchers to investigate the neural circuit underpinnings of a wide array of behaviors that cannot be studied under head-fixed conditions, such as sleep, reward seeking, learning and memory, social behaviors, and feeding. Importantly, the miniscope has broadened our understanding of how neural circuits can go awry in animal models of progressive neurological disorders, such as Parkinson’s disease. Continued miniscope development, including the ability to record from multiple populations of cells simultaneously, along with continued multimodal integration of techniques such as electrophysiology, will allow for deeper understanding into the neural circuits that underlie complex and naturalistic behavior.
