Full textAbstract:
Employing a uses-and-gratifications approach, we examined the motives for following sports using the social media application Snapchat (version 9 [9.27.5.0 iOS/9.20.6.0] Andr). In Step 1 of the study, participant provided narratives ( n = 49) about their motivations for using Snapchat to follow sports. In Step 2, an online survey asked participants ( N = 263) to respond to 39 motive statements gleaned from narratives obtained in Step 1 as well as measures of points of attachment (POA), overall time spent viewing a variety of sports, and to rank the importance of various social media channels. Overall, four motives for using Snapchat to follow sports were conceptualized across 21 items (i.e., ease and convenience, behind the scenes, vicarious experience, unique points of view). Next, using regression analyses, we found that age, POA, social media preferences, and different sports viewed predicted motives for using Snapchat to follow sports to varying degrees. Theoretical implications and considerations for future research are also discussed.

Full textAbstract:
This study investigated whether the Point of attachment (POA) theory can be used to measure the consumption intention on go and watch offline eSports games. The admiration for players, social interaction, and on-site consumption requirements for viewing offline eSports competitions are prioritized. In addition, eSports fans in various regions may have distinct consumption concepts and consumption patterns. Thus, this study surveyed China (n = 156) and South Korea (n = 127) eSports fans who subjectively perceive themselves to be fans of eSports player(s) and who have observed at least one offline eSports game. The results demonstrate that player attraction and socialization have positive and significant effects on offline consumption factors. There is no correlation between previous consumption behavior and satisfaction, but dining shows a significant positive effect on satisfaction. Moreover, there is a strong relationship between satisfaction and future attendance intention. In addition, effect of eSports fan attachment on future visit intentions are measured and there is no correlation between the two variables. The front end of the path in the new model's varied between Chinese and Korean supporters. Finally, theoretical and practical implications of this study are discussed.

Full textAbstract:
Optimizing the balance between different handover parameters for network selection is one of the challenging tasks for seamless communication in heterogeneous networks. Traditional approaches for network selection are mostly based on the Receive Signal Strength (RSS) from the Point of Attachment (PoA) of a network. Most of these schemes are suffered from high handover delay, false handover indications, and inappropriate network selection for handover. To address these problems, we present an optimized network selection scheme based on the speed of a mobile node. A mechanism based on two different thresholds on the speed of a Mobile Node (MN) is integrated in the proposed scheme. If the speed of an MN is greater than any of the threshold, the MN performs handover to a particular network. We employ Grey Relational Analysis (GRA) in the proposed scheme to select the best PoA of the selected network. Similarly, to deal with false handover indications, we proposed an optimized handover triggering technique. We compare our proposed scheme with existing schemes in context of energy consumption for scanning, frequent and failed handovers, packet loss ratio, and handover delay. The proposed scheme shows superior performance and it outperforms existing schemes used for similar purpose. Moreover, simulation results show the accuracy and performance of the proposed scheme.

Full textAbstract:
As a promising polymer for the production of biomaterials and drug delivery systems, poly(lactic acid) (PLA) is characterized by its relative hydrophobicity, as well as its chemical and biological inertness. Here, we aimed to improve the biological properties of PLA-based materials via the covalent attachment of a hydrophilic biocompatible glycopolymer, namely poly(2-deoxy-N-methacrylamido-D-glucose) (PMAG) on their surface. PMAG is a water-soluble polymer that contains glucose units in its side chains, which are responsible for good biocompatibility and the ability to attach bioactive molecules. In the developed protocol, PMAG was synthesized by controlled radical polymerization in the presence of a reversible addition–fragmentation chain transfer (RAFT) agent, followed by the conversion of glycopolymer terminal dithiobenzoate functionality into a primary amino group (PMAG-NH2). PLA-based films served as model aliphatic polyester materials for developing the surface biofunctionalization protocol. According to that, PMAG-NH2 covalent immobilization was carried out after alkali treatment, allowing the generation of the surface-located carboxyl groups and their activation. The developed modification method provided a one-point attachment of hydrophilic PMAG to the hydrophobic PLA surface. PMAG samples, which differed by the degree of polymerization, and the variation of polymer concentration in the reaction medium were applied to investigate the modification efficacy and grafting density. The developed single-point polymer grafting approach provided the efficient functionalization with a grafting density in the range of 5–23 nmol/cm2. The neat and modified polymer films were characterized by a number of methods, namely atomic force microscopy, thermogravimetric analysis, ellipsometry, and contact angle measurements. In addition, an ArgGlyAsp-containing peptide (RGD peptide) was conjugated to the PMAG macromolecules grafted on the surface of PLA films. It was shown that both surface modification with PMAG and with PMAG-RGD peptide enhanced the adhesion and growth of mesenchymal stem cells as compared to a neat PLA surface.

Full textAbstract:
One of the challenges to achieving smooth communications in heterogeneous networks is to find the right balance between various handover parameters for network selection. The Receive Signal Strength (RSS) from a network's Point of Attachment (PoA) is the primary factor used in traditional approaches to network selection. Therefore, network selection is vital for a successful handover in the vehicle communications network. However, vehicles moving through such diverse networks faced difficulties like frequent unwanted handovers, selecting the wrong candidate networks for handovers, and taking too long to finish the drawn-out handover procedure, which results in failed handovers. All of these factors will impair the efficiency of the handover process, which will affect the smooth operation of the vehicles. Hence, the main idea of this research is to improve the handover network performance selection performance. The proposed work is for vehicles to self-evaluate a candidate list of Access Points (AP) that are located in the vehicle movement direction and select the best underlying candidate network. In this project, the network selection framework of the vehicle communications network with the distance between the target candidate and the trajectory of the vehicle movement was developed as well as the vehicle mobility information. The important parameters which are the relative direction index, proximity index and residence time index are chosen to identify the best candidate network. Once the target of the base station has been identified, then the optimum value of the distance is calculated using the Particle Swarm Optimization (PSO) technique to initiate the handover process. The performance of the proposed handover network selection is simulated and evaluated using MATLAB software. The results show that the proposed handover network selection method improved the successful handover rate as compared to the conventional method.

Full textAbstract:
Finding a suitable support is a key process in the life history of climbing plants. Those that find a suitable support have greater performance and fitness than those that remain prostrate. Numerous studies on climbing plant behavior have elucidated the mechanistic details of support-searching and attachment. Far fewer studies have addressed the ecological significance of support-searching behavior and the factors that affect it. Among these, the diameter of supports influences their suitability. When the support diameter increases beyond some point, climbing plants are unable to maintain tensional forces and therefore lose attachment to the trellis. Here, we further investigate this issue by placing pea plants (Pisum sativum L.) in the situation of choosing between supports of different diameters while their movement was recorded by means of a three-dimensional motion analysis system. The results indicate that the way pea plants move can vary depending on whether they are presented with one or two potential supports. Furthermore, when presented with a choice between thin and thick supports, the plants showed a distinct preference for the former than the latter. The present findings shed further light on how climbing plants make decisions regarding support-searching and provide evidence that plants adopt one of several alternative plastic responses in a way that optimally corresponds to environmental scenarios.

Full textAbstract:
Bioactivity is an important aspect in biomaterial science ensuring materials used are safe for clinical application. The study describes fabrication of composites containing polylactic acid (PLA) – polyethylene glycol (PEG) with incorporation of sol-gel derived 45S5 bioactive glass (BG). Thermal analysis via Differential Thermal Analysis shows a favorable point over degree of crystallization that influence cells attachment, although non-significant difference in values indicates BG has homogenously dispersed. This correlates to X-ray diffraction analysis where non-significant difference is seen in intensities of the diffraction peaks, which confirms low impact of BG brittleness properties over the fabricated composite. Composites’ pH and degradation study in Simulated Body Fluid shows a steady increment profile over time and lower degradation rate for the composite after incorporation of BG. In vitro cell proliferation study also showed that HDF cells seeded on composite film of P/BG2.5 exhibit highest cell viability with steady increment of proliferation throughout the observation period.

Full textAbstract:
The development of nanofibrous membranes with tunable wettability, degradation, and biocompatibility is highly keen for biomedical applications, including drug delivery and wound dressing. In this study, biocompatible and biodegradable nanofibrous membranes with antioxidant properties were successfully prepared by the electrospinning technique. The membranes were developed using polylactic acid (PLA) and polyethylene oxide (PEO) as the matrix, with the addition of grape seed extract (GSE), a rich source of natural antioxidants. The nanofibrous membranes were thoroughly characterized both from the materials and from the biocompatibility point of view. PLA and PLA/PEO nanofibers showed high encapsulation efficiency, close to 90%, while the encapsulated GSE retained its antioxidant capacity in the membranes. In vitro release studies showed that GSE diffuses from PLA/GSE and PLA/PEO/GSE membranes in a Fickian diffusion manner, whose experimental data were well fitted using the Korsmeyer-Peppas model. Furthermore, a higher controlled release of GSE was observed for the PLA/PEO/GSE membrane. Moreover, culturing experiments with human foreskin fibroblast (HFF1) cells demonstrated that all samples are biocompatible and showed that the GSE-loaded PLA/PEO nanofibrous membranes support better cell attachment and proliferation compared to the PLA/GSE nanofibrous membranes, owing to the superior hydrophilicity. In summary, the results suggested that the GSE-loaded membranes are a promising topical drug delivery system and have a great potential for wound dressing applications.

Full textAbstract:
In the field of tissue engineering, there are several issues to consider when designing biomaterials for implants, including cellular interaction, good biocompatibility, and biochemical activity. Biomimetic mineralization has gained considerable attention as an emerging approach for the synthesis of biocompatible materials with complex shapes, categorized organization, controlled shape, and size in aqueous environments. Understanding biomineralization strategies could enhance opportunities for novel biomimetic mineralization approaches. In this regard, mussel-inspired biomaterials have recently attracted many researchers due to appealing features, such as strong adhesive properties on moist surfaces, improved cell adhesion, and immobilization of bioactive molecules via catechol chemistry. This molecular designed approach has been a key point in combining new functionalities into accessible biomaterials for biomedical applications. Polydopamine (PDA) has emerged as a promising material for biomaterial functionalization, considering its simple molecular structure, independence of target materials, cell interactions for adhesion, and robust reactivity for resulting functionalization. In this review, we highlight the strategies for using PDA to induce the biomineralization of hydroxyapatite (HA) on the surface of various implant materials with good mechanical strength and corrosion resistance. We also discuss the interactions between the PDA-HA coating, and several cell types that are intricate in many biomedical applications, involving bone defect repair, bone regeneration, cell attachment, and antibacterial activity.

Full textAbstract:
We have reported a new polyethylene glycol (PEG)-modified, hemoglobin-based O2 carrier (MP4) with novel properties, including a large molecular excluded volume and low Po2 necessary to obtain 50% O2 (∼6 Torr). To evaluate the ability of MP4 to transport O2, we compared it with PEG-modified albumin (MPA) using the identical chemistry of attachment of PEG chains. The resulting solutions were well matched with respect to all physical properties except that MP4 is an O2 carrier, whereas MPA is not. An additional solution, 10% pentastarch, was matched with the PEG-modified proteins with regard to oncotic activity and viscosity but does not contain PEG. The model used to evaluate O2 transport was continuous exchange transfusion in the rat until the hematocrit was virtually unmeasureable. Objective end points included survival and the onset of anaerobic metabolism, signaled by acid-base derangement and accumulation of lactic acid. Continuous exchange transfusion of 2.5 blood volumes in rats ( n = 5 in each treatment group) was carried out over 60 min, such that the final hematocrit was between 0 and 5% in all animals. Animals were observed for an additional 70 min, when survivors were killed. Overall survival for the MP4 animals was 100%; no animal that received either pentastarch or MPA survived. The hematocrit at which lactic acid began to rise was ∼14.8% in both pentastarch and MPA animals and 7.4% in the animals that received MP4. In all groups, the total hemoglobin was ∼5 g/dl at this point. We conclude that, despite its low Po2 necessary to obtain 50% O2, MP4 effectively substitutes for red blood cell hemoglobin in its ability to oxygenate tissues in extreme hemodilution.

Full textAbstract:
The focus of this work was to develop a deeper understanding of the mechanisms of flame stabilization and extinction for shear layer stabilized, premixed flames. Planar experimental studies were performed in the attachment point region of an inner shear layer stabilized flame in an annular, swirl combustor. Through high resolution, simultaneous PIV & CH-PLIF measurements, the instantaneous flow field and flame position was captured enabling the characterization of 2D flame stretch and velocity conditions in the attachment point region. In addition, measurements performed at various equivalence ratios and premixer velocities provided insight into the physics governing blowoff. Most notably, these studies showed that as lean blowoff conditions are approached by decreasing equivalence ratio, the mean stretch rates near the attachment point decrease but remain positive throughout the measurement domain. In fact, compared to numerically calculated extinction stretch rates, the flame becomes less critically stretched as equivalence ratio is decreased. Also, investigation of the flame structure at the leading edge of the flame showed strong evidence that the flame is edge flame stabilized. This was supported by inspection of the CH-PLIF images, which showed the CH-layer oriented tangent to the flow field and terminating abruptly at the leading edge. Lastly, the flame anchoring location was observed to be highly robust as the mean flame edge flow conditions and mean location of leading edge of the flame were insensitive to changes in equivalence ratio, remaining nearly constant for values ranging from 0.9 to 1.1. However, at the leanest equivalence ratio of 0.8, the flame leading edge was located farther downstream and subject to much higher flow velocities. These results thus suggest that blowoff is the result of a kinematic balance and not directly from stretch induced flame extinction.

Full textAbstract:
This thesis explores the relationship between place attachment and pro-environmental behaviour expressed by visitors to Point Pelee National Park. Place attachment, the functional, cognitive and emotional bond with a place, may play a role in promoting environmentally responsible behaviours. This may be especially true of place-specific pro-environmental behaviours; however place attachment may also have a "carry-over" effect in that its impact on individuals' self identity may also foster pro-environmental behaviour in individuals' every day lives. <br /><br /> An exploration of these relationships was achieved, first by measuring the intensity of place attachment and pro-environment behavioural intentions expressed by visitors to Point Pelee National Park. This was followed by an examination of the relationship between these two constructs using correlation analysis and structural equation modeling. Data was collected with a mail-based self-completed questionnaire. A quota sample of visitors to Point Pelee National Park was utilized. A response rate of 32% (<em>n</em> = 355) was achieved. <br /><br /> The relationship between place attachment and pro-environmental intentions was explored further through the measurement of several related variables. These factors include place satisfaction (based on an appraisal of nature, social and activity-based environments), motivation for visiting the park (related to social interaction and nature observation, as well as activity-based and learning opportunities), distance between the park and visitors' residences, membership in environmental organizations, and visitation patterns including visitation to the park during childhood, length of affiliation with the park, length of visit to the park, and frequency of visitation to the park. Theoretical and empirical research suggests that these factors may affect place attachment, pro-environment behavioural intentions, and/or the relationship between these two constructs. <br /><br /> Study results found positive associations between place attachment and all of these variables with the exception of visitation motives associated with learning and engaging in a favourite activity. The strongest predictive relationships were observed with anti-substitution (the inability of an individual to substitute the park for another destination because of a lack of resources such as time or money or a lack of awareness of comparable sites) followed by frequency of visits to the park; park commitment (based on Friends group membership and donations of time and money to the Friends group); Friends of Point Pelee (FoPP) membership; and park relationship (which was based on visitation to the park as a child and length of affiliation); and, satisfaction with the park. <br /><br /> Results support the proposition that place attachment has a strong positive association with both park-specific pro-environment behavioural intentions (e. g. , Write letters in support of Point Pelee N. P. and similar protected areas) as well as general pro-environment behavioural intentions (e. g. , Pay extra for transportation if it is environmentally-friendly). Place attachment strongly predicted park-specific, and moderately predicted general pro-environmental intentions. A number of other variables had an indirect effect on park-specific intentions; notable effects were demonstrated by frequency of visits; park relationship; visitation to the park as a child; place satisfaction; social satisfaction; FoPP membership; and, park commitment; anti-substitution. These affects were mediated by place attachment. After place attachment the strongest predictors of park-specific intentions were anti-substitution; frequency of visits; park commitment; and, general environmental commitment (which was based on membership in an environmental organization and donations of time and money to that organization). <br /><br /> Place attachment was not the only direct predicator of general pro-environmental intentions; general environmental commitment and membership in an environmental organization also directly predicted general pro-environmental intentions. Notable indirect effects, mediated by place attachment were produced by frequency of visits; park relationship; FoPP membership; park commitment; and anti-substitution. The strongest predictors of general pro-environmental intentions were general environmental commitment, followed by place attachment, membership in an environmental organization, and frequency of park visitation. <br /><br /> These findings correspond with much of the literature published on place attachment formation and the development of pro-environmental behaviours. The most notable contribution of this study is its comparison of place attachment's impact on general versus place-specific behaviours, and the role that several related variables play in this relationship.

Full textAbstract:
<p> The purpose of this study was to investigate the relationships between attachment style, shyness, shame, and college persistence and grade point average. While considerable research was conducted to examine these variables in children, less is known about how these variables interact in a college setting. This study used a quantitative, non-experimental correlational design to analyze these variables in relation to college freshman students at a for-profit university, with locations throughout the United States. Over 2,000 freshman students between 18 and 40 received e-mails via the university’s communication department asking them to participate in this study by responding to three surveys. Participants completed The Experiences in Close Relationships to measure attachment style, the Cheek and Buss Shyness scale to measure shyness, and the Compass of Shame scale to measure shame. Persistence was measured by examining whether students were registered and attending classes the semester following the survey distribution. Students also completed a demographic survey. In all, 143 participants completed surveys, with a final sample of 99 once the data were analyzed for transfer credit and outliers. Results were examined using logistic regression analysis to determine relationships between attachment style, shyness, shame, and persistence. A multiple linear regression analysis was used to analyze relationships between the predictor variables and cumulative grade point average. Results of this study indicated that there were no significant relationships between the predictor variables and persistence and grade point average. A discussion of results explores possible explanations including recommendations for future research in regards to attachment style, shyness, shame and their impact on college student success.</p>

碩士<br>元智大學<br>國際企業學程<br>99<br>In recent years, the number of convenience stores has become more and the density of their locations is higher that makes the market more competitive. Therefore,
convenience stores have restored to various marketing strategies to increase their sales. In addition, figures have caused an epidemic wave now and they could bring customers’ attention. Most important, they could affect purchase intention. Consequently, convenience stores use the method of point-collected figure to attract customers shop in the stores. As a result, it becomes a popular topic and short supply.
This study aims to know convenience stores use method of figure marketing whether could achieve the goal that customers generate the store loyalty. Besides, we discuss the relationship between figures and convenience stores by attitude theory. Through viewing the factors of customers’ attachment toward figures and convenience stores whether could generate the involvement to convenience stores and
then depend on it. The results allow convenience store operators that can predict the behavioral response of consumers when proceed this type of marketing activities.
The research use online sampling survey to analysis data and effective questionnaire are collected 619 respondents. Then we use the structural equation modeling of AMOS18 to test the hypotheses. The results of this study shows that convenience stores use figures to market could generate the attachment of conveniences stores by the customers’attachment to the figures. Besides, using customers attach to figure that could enhance the convenience stores’ attachment then influence involvement. Finally, customers attach to convenience store will enhance the figures’ attachment then positive influence involvement and achieve the convenience store loyalty.

碩士<br>淡江大學<br>教育心理與諮商研究所碩士班<br>105<br>The purpose of this study was to examine how self-regulation harmonize and adjust attachment working models in intimate relationships. Although the attachment researches focused on the importance of dyadic and group relationships, there is much less attention on how self-regulation benefited and adjusted the intimate relationships. This study focused on individuals explored their implicit attachment-base processes with their partners and corrective their early insecure attachment experiences, depth interviews with a total of six adults aged between 20 and 30 participated in conducted by the researcher and the data was interpreted, and analyzed via hermeneutic phenomenological method in a structured form.
The result shows four views which were as followed:(1) As individuals interacted their partners, they repeated their previous attachment experiences to manage intimate relation, and coped with their emotions automatically , it can be amplified by events that transpire with their relationships or in the wider environment. Then the insecure coping strategies would damage their intimate relationships.(2) The individuals could regulate their attachment-base processes as they were activated by the fear of rejections or abandonment. The partners could interacted with caring and trusting connections and individuals could adjust their emotional difficulties in the processes. The above allowed to correct their attachment working models and facilitate more attachment security. The individuals differentiated gradually and developed a trusting relationships, and maximize the likelihood of a mutual outcomes in the future. (3) This type of anxiety attachment style not only through the separation of independent characteristics, and through a healthy positive partner interaction, increase interaction with the partner satisfaction and stability of the feelings of the two facing the relationship. (4)The individuals overviewed their life span, and facilitated healthy attachment in their intimate relationships. Therefore, some concrete suggestions are proposed based on the above conclusions as a reference for seniors, anxiety attachment style and future researches.

Full textAbstract:
M. Tech.<br>Background: No substantiated theory exists by which chiropractic adjustments are known to correct myofascial trigger points (MTrPs). Myofascial trigger points are theorized to be either a primary muscle dysfunction or a secondary manifestation to central/ peripheral neurological mechanisms. Chiropractic adjustments are theorized to exert their therapeutic influence either primarily through biomechanical effects and/ or via neurophysiological mechanisms. Objective: The objective of this study was to investigate the effects of chiropractic adjustments on chronic, active rhomboid MTrPs, by comparing the clinical effects attained with rhomboid attachment-segment (C7-T5) relative to rhomboid innervation-segment (C4 and/ or C5) chiropractic adjustments. Setting: University of Johannesburg Chiropractic Day Clinic in Johannesburg, Gauteng. Participants: Thirty female subjects selected from the general population (from 18 to 40 years) were randomly divided into two different treatment groups of 15 each. Methods: The subjective information required the completion of the Subjective Pain and Discomfort Questionnaire, including the Numerical Pain Rating Scale (NPRS). The objective measures collected were pressure-pain threshold (PPT) and range of motion measurements using the algometer and digital inclinometer, respectively. Additionally, the change in the number of active MTrPs over the treatment period was recorded. All measurements were recorded at the first, third and fifth consultations, over a 3 to 4 week period. The data gathered were then statistically analyzed with the use of a 95% confidence interval. The nonparametric Friedman and Wilcoxon Signed Rank tests were used for the intragroup comparisons, and the Mann Whitney- U test was used for the intergroup comparisons. Interventions: Treatment group 1 received upper-thoracic/ attachment- segment chiropractic adjustments, and treatment group 2 received mid-cervical/ innervation-segment chiropractic adjustments. The research project was carried out so that both groups received 5 treatment sessions over 3 to 4 weeks. Results: There were no statistically significant results obtained for intergroup comparisons. Attachment-segment chiropractic adjustments revealed statistically significant changes in NPRS values (p=0.000), PPT values (p=0.000), cervical spine right lateral flexion range (p=0.004), thoracic spine extension (p=0.005) and left rotation range (p=0.003) over time. Innervationsegment chiropractic adjustments revealed statistically significant changes in NPRS values v ii (p=0.001), cervical spine right rotation (p=0.003), thoracic spine flexion (p=0.001) right lateral flexion (p=0.001) and left rotation (p=0.005) over time. Conclusions: This study does not suggest that attachment-segment or innervation-segment chiropractic adjustments possess greater clinical efficacy relative to one another in terms of improving the clinical picture associated with chronic, active rhomboid MTrP activity. In a further study, a larger sample size will be necessary to identify subtle changes in measurement parameters.

The Article lays out the framework that translates the general grant of coverage into an actual financial response. It sets out the principles that determine at what point the insurer's liability to the policyholder is engaged; the relevance and consequences of underlying insurance; how the level of policy response to an excess liability is determined; and how it is limited. It also addresses the financial complications that may develop when a policyholder notifies an occurrence to the insurer, and subsequently notifies an integrated occurrence that includes the earlier notified individual occurrence. Finally, the Article addresses the special circumstances relevant to the presence of an insured joint venture, partnership, or other similarly organized, non-corporate entity in the equation.

This article describes the forty-year history of publications in quantitative political methodology. It also illustrates that the range and scope of outlets now available stands in dramatic contrast to what existed forty years ago. It begins with material in leading general journals, the American Political Science ReviewAPSR and the American Journal of Political Science (AJPS). From there, it traces the development of more specialized venues, such as Political Methodology (POM), Political Analysis (POA), the Political Methodologist (TPM), and the Sage Quantitative Analysis in the Social Sciencesseries (QASS). From the vantage point of today, the mid-2000s, a political scientist seeking to publish a paper in quantitative methods has at least five opportunities.

This essay examines the relation of the religious universalism of the Catholic Church to nationality, patriotism, and the ideology of nationalism. In the abstract, one expects there to be a tension between monotheism and the existence of nations. However, the teachings of the Church are, in fact, remarkably nuanced, recognizing a natural, legitimate attachment to one’s fatherland or motherland. During the examination, problems of the point of departure and scope of the analysis are taken up, as well as historical examples such as theKulturkampfand the Church’s principle of subsidiarity, including the bearing on the latter on corporate personality and the development of the individual’s image of the self.

Most of us find social encounters rewarding, especially when we encounter those with whom we are familiar and have built up a relationship. From an evolutionary point of view, this is not surprising; human beings are fundamentally social organisms, and human development and functioning occur within a social context. The origin of individual differences in the capacity to experience social reward is likely to involve a complex interplay of genetic and environmental variables, including genetic variation, early experience and current situational factors. A few individuals seem to lie at the lower extreme of this continuum, experiencing little or no positive feelings during affiliative interactions. This chapter deals with the psychological and behavioral traits that characterize these uncommon individuals and reviews the mechanisms likely to cause their emotional detachment. The chapter then discusses the importance of aversive early experience in promoting an avoidant style of adult attachment and the role of the brain opioid system and genetic polymorphisms in mediating diminished hedonic response to affiliative interactions.

Full textAbstract:
Children take their first steps, produce their first words, and become able to solve many new problems seemingly overnight. Yet, each change reflects many other previous developments that occurred in the whole child across a range of domains, and each change, in turn, will provide opportunities for future development. This book proposes that all change can be explained in terms of developmental cascades such that events that occur at one point in development set the stage, or cause a ripple effect, for the emergence or development of different abilities, functions, or behaviors at another point in time. The authors argue that these developmental cascades are influenced by different kinds of constraints that do not have a single foundation: They may originate from the structure of the child’s nervous system and body, the physical or social environment, or knowledge and experience. These constraints occur at multiple levels of processing and change over time, and both contribute to developmental cascades and are the product of them. The book presents an overview of this developmental cascade perspective as a general framework for understanding change throughout the lifespan, although it is applied primarily to cognitive development in infancy. The book also addresses how a cascade approach obviates the dichotomy between domain-general and domain-specific mechanisms. The framework is applied in detail to three domains within infant cognitive development—namely, looking behavior, object representations, and concepts for animacy—as well as two domains unrelated to infant cognition (gender and attachment).

Full textAbstract:
This book supports researchers who need to generate random networks, or who are interested in the theoretical study of random graphs. The coverage includes exponential random graphs (where the targeted probability of each network appearing in the ensemble is specified), growth algorithms (i.e. preferential attachment and the stub-joining configuration model), special constructions (e.g. geometric graphs and Watts Strogatz models) and graphs on structured spaces (e.g. multiplex networks). The presentation aims to be a complete starting point, including details of both theory and implementation, as well as discussions of the main strengths and weaknesses of each approach. It includes extensive references for readers wishing to go further. The material is carefully structured to be accessible to researchers from all disciplines while also containing rigorous mathematical analysis (largely based on the techniques of statistical mechanics) to support those wishing to further develop or implement the theory of random graph generation. This book is aimed at the graduate student or advanced undergraduate. It includes many worked examples, numerical simulations and exercises making it suitable for use in teaching. Explicit pseudocode algorithms are included to make the ideas easy to apply. Datasets are becoming increasingly large and network applications wider and more sophisticated. Testing hypotheses against properly specified control cases (null models) is at the heart of the ‘scientific method’. Knowledge on how to generate controlled and unbiased random graph ensembles is vital for anybody wishing to apply network science in their research.

Full textAbstract:
Ethnicity, nationalism, and migration are popular topics in many academic disciplines, but research on public opinion in these areas has suffered from a lack of good data, disciplinary fragmentation, and a dearth of studies that engage one another. This is evident in the case of public opinion survey research undertaken in the world’s hotspots of ethnic conflict. As a result, ethnic conflict scholars have had to rely on proxy measures or indirect studies to test “opinion” towards ethnicity and nationalism in the developing world. In the developed world, however, there is more to work with in terms of opinion measurements. A prominent example is the European Union’s “Eurobarometer” surveys, which gauge attachment to and identification with “Europe” and the individual nation. Research on national identity and ethnic conflict has often been the starting point for theories of public opinion regarding immigration. A common finding is that there is a weak connection (if any) between opinion and policy on the immigration issue. Several areas need to be addressed as far as research is concerned. For example, the picture of xenophobic hostility in rich countries must be understood in a context of general changes in word migration patterns, with some emerging economies also experiencing high levels of immigration, and concurrent anti-immigrant public opinion. Two shortcomings of the literature also deserve closer attention: a focus on developing-to-developed country migration; and a lack of analyses that combine push and pull factors, to measure their relative causal weight in terms of bilateral immigration flows.

AbstractAdolescence is a sensitive developmental period, with important changes occurring at biological, cognitive, emotional and social levels. As evidenced by several studies, adolescence is also a vulnerable period for the onset of serious mental disorders, which then tend to persist into adulthood. While there is ample evidence concerning risk factors of mental disorders in adolescence, a lot less is known about protective factors: however, one important protective factor to have emerged from recent research concerns attachment security. The aim of the current paper is to explore the effects of attachment on emotion regulation (in terms of physiological reactivity), autonomy and relatedness, and behavioral problems in adolescence, and how attachment is in turn influenced by parental reflective functioning (PRF), parenting behaviors (operationalized in terms of behaviors promoting and undermining autonomy relatedness) and parenting stress (in terms of cortisol reactivity). The findings point to the potential utility of interventions aimed at enhancing attachment security, thus allowing a better psychological adjustment, and at improving PRF, especially in divorced families, given its protective effect on parenting stress and parenting behaviors.

AbstractGerman citizens usually leave their home country voluntarily and face fewer barriers, e.g. in terms of freedom of travel or labour market integration. However, when arriving in their host country, they are confronted with the need to adapt to life in a new society. Analysing data from the German Emigration and Remigration Panel Study, we found that half of the emigrants developed a sense of belonging to their new host society. Moreover, we set out to examine this development of host country attachment. Guided by findings from acculturation and expatriate attachment research, we identified factors potentially contributing to host country attachment and tested these in a series of regression models. Permanence of the intended stay is the strongest predictor, and social integration also plays an important role. Host country language competence is also important for the identification processes. Regarding cultural distance, our findings suggest an inverted U-shaped relationship with certain cultural novelty facilitating the development of host country belonging. Moreover, the data point to a complex relationship between cultural characteristics of the target country and factors related to an emotional settlement.

Abstract Various frameworks have been employed in the monitoring and evaluation of tourism impacts in protected areas (PAs). Aware of their limitations, this chapter adopts a longitudinal, stakeholder-driven approach to examine the emerging impacts to gateway communities near PAs in Batanes, the Philippines, as part of a larger initiative to establish a sustainable tourism observatory in the islands. Findings show perception of impacts to be interconnected with discourses on the role of tourism in development, conflicts over resource use and place identity, and reveal the strength of a discursive approach. Anchored in stakeholder engagement, eliciting factors that underlie tourism impacts in a PA include weak local governments with strong central administrations focused on maximizing economic growth over other concerns, such as sustainability, and robust place attachment driven by rootedness. They point to the importance of improving governance and raising the possibility of co-management as a mechanism to reform PA management.

Full textAbstract:
AbstractReception centres for asylum seekers, and “camps” more broadly, are a subject of increasing interest in refugee, housing and border studies. Only a fraction of this literature, however, draws on proper ethnographic fieldwork within these infrastructures. A case in point is a recent study I have conducted in an asylum centre in northern Italy. My research focus was on the lived experience of the built environment and on the spatial and temporal boundary-making among residents, and between the latter and service providers. Within rooms and shared kitchens that operate as proxies of a domestic space, people do not simply “wait”. They engage in forms of space appropriation (and to a lesser extent, attachment) that illustrate the significance of homemaking in temporary and unhomely settings. Moreover, the social and material inner space of an asylum centre is far from homogeneous. Against accounts of undifferentiated ghettos or non-places, the chapter illustrates the thresholds and layers of domesticity that refugees as guests negotiate, and that an ethnographer as their guest can capture. Without dismissing the attendant dilemmas, I show the contribution of a “being in” approach to co-produce knowledge on inner domestic routines and cultures, on the ways to (re)present oneself, on the traces of past dwelling. A refugee room gives little of an external view, as long as someone gets stuck in. Yet, it provides a uniquely internal view on their everyday life experience and prospects.

Full textAbstract:
The fourth chapter is devoted to uncovering Mou’s idea of “authentic subjectivity.” According to Mou, this new paradigm of subjectivity was inaugurated by Confucius and Mengzi and reached its zenith in specific currents of Song-Ming Neo-Confucian thought. Through an original reformulation and systematization of this inheritance, Mou develops his “moral metaphysics,” in the framework of which his conception of subjectivity finds its definitive foundation. The “authentic subject” should not be confused with one of the poles of the dyad subject/object operating in Western, horizontal and knowledge-based mainstream philosophy. By contrast, it represents the culminating point of the vertical reorientation of the idea of the self. The previous chapters identify some distinguishing characteristics of the vertical self: dynamism, performativity, and self-transcendence. Moral metaphysics aims to bring any of these characteristics to full completion. Regarding dynamism, the moral self or authentic subject manifests itself as a process of uninterrupted liquefaction of any concretion and attachment. Mou distinguishes between a “little self” and a “great self.” The little self is the mind of habit, an inner domain constituted by psychological states, and it is constantly construed through a narrative interweaving of our memories. This inner domain is the province of qualia. In contemporary philosophy of mind, qualia are the subjective and qualitative aspects of our mental lives, the inner side of phenomenal experiences. They are echoes and traces passively produced by sensorial contact with the external world and are directly accessible only to privately experiencing subjects. In Critique of the Cognitive Mind, Mou called them “psychological states,” contrasting them with perception, that is, the ever-present ability of the mind to emancipate itself from any passive reverberation and affirm itself as pure dynamical act and ever-resurgent new beginning. Translated in a performative and practical dimension, Mou understands the little self or the unauthentic subject as a conglomerate of attachments and habits residually left behind in our attempt to dominate and control the objective world. The great self attainable in our moral deeds is a higher spiritual state that overcomes the distinction between the inner and outer worlds. The dynamism of self-transcendence actualized in my moral agency is a constant awakening from selfish slumber to the infinitude of my being one with all things. As Mengzi expresses it, “All things are already complete in us.” The unparalleled contribution of the Confucian tradition lies in the primacy of morals. It is critical to highlight that in Mou’s thought “morals” has a more comprehensive semantic spectrum than in Western philosophy because it is not a specific branch of knowledge dealing with ethical virtues and freedom of will, as epitomized in Kant’s Critique of Practical Reason. Morals and the moral self possess a performative and metaphysical dimension, including the ability to decipher the meaning embedded in reality, the action of conferring value to things, respecting them as end-in-itself, and avoiding the reduction of the world to a mere instrument, and finally the intuition of the universe as one with myself. The Western horizontal paradigm, in which ethical principles are deduced from the knowledge of being, is unable to explain phenomena such as moral failure and objectively justify the freedom of will. Therefore, Mou suggests that we begin our philosophical inquiry with the moral experience of value, rather than the relation between the mind and external objects. Confucian tradition offers a prime example of moral experience in Mengzi’s apologue of the “child by the well.” When I see my child about to fall into a well, Mengzi argues that my feelings of compassion are immediately awakened. What I perceive in my emotional intelligence is a sense of urgency and concern that results in the spontaneous and immediate action of grabbing the child. In this archetypal experience, the self emerges as a vital vibration of urgency and agency, witnessing my being-one-body with the child. The infinitely irreducible value of the world possesses a force of self-manifestation and actualizes itself in my all-embracing responsiveness. According to Mou, I become retrospectively aware of my moral mind as a universal, active interconnectedness of all that exists, preceding any separation between subject and object. With respect to the Daoist subject analyzed in Chapter 3, the conception of the performative subject that aims for self-realization is reconfirmed, as is the idea of jingjie. However, Mou’s assertion that the full meaning of the subject is inaugurated by Confucianism reveals that the characteristics of the self (i.e., dynamism and reflexivity) can be fully appreciated only when the moral self comes to the forefront. According to Mou, the merit of orthodox Confucian teaching is to have placed something maximally positive and attainable through human freedom, that is, the moral self and the supreme spiritual level attainable through my effort of self-cultivation. Daoism’s diaphanous subject maintains structural passivity. The jingjie of the Daoist saint, reached through a systematic withdrawal from any purpose or concrete engagement with reality, is a mental landscape in which the self and nothingness, that is, the inchoate origin of the cosmos, merge into one. From this point, the Daoist self can only contemplate the exuberant gushing out of myriad things from the origin, being careful to constantly efface itself to avoid obstacles to the endless metamorphosis of things. In Mou’s moral metaphysics, the moral mind replaces nothingness as a creative inception. The self is required to actively participate, embodying and actualizing the moral principles in minute objective circumstances, without letting anything out of the sphere of concern and responsibility. In addition to dynamism and performativity, reflexivity and self-awareness are the third characteristic of the self. The Daoist diaphanous subject, in attending to the multifarious manifestation of beings, can look back at itself and become aware of the unity between the universe and the transparency of the self, which is the condition for this manifestation. However, because of the necessity of avoiding attachment to the self and constantly restoring the transparency of the mind, it is nothing more than an ephemeral gleam. In contrast, Mou’s moral self, in performing ethical deeds, realizes and actualizes the principle that it embodies every single thing. The specific circumstances are not given through a visually based detached contemplation but are concretely actualized in their value and meaning through active participation and concern. In “bringing things to realization without any of them being lost” (ti wu er bu ke yi 體物而不可遺), the “mind of benevolence” concretizes the moral principle by penetrating into the infinite particularity of situations. Through my moral activity, I come to realize myself as one with the moral mind, which is the highest spiritual state. Here, I operate at the ontological level that Mou identifies with the Confucian idea of inherent nature (xing 性). Nature is brought to perfect manifestation through creative efforts to reach the spiritual state of the moral mind. Nature is not a static substance but a living principle that possesses the ability to self-actualize. Mou valorizes the idea, stemming from the very beginning of Chinese thought—the Yijing (Classic of Change)—that reality is a living, dynamic flux of transformation and an interacting web of mutual responsiveness. As Mou declared in Critique of the Cognitive Mind, reality in itself is holistic, interconnected, and pervaded with meaning. However, in the absence of a manifesting mind, this organic order of things, which is their principle and value-in-itself, remains only a latent ontological property. Only in self-perfected human beings are the mind and nature, manifestation and content, inseparable. The manifestation proper to the moral mind is not merely a symbolic expression, but is the concretization of the moral principle into the infinite particularity of situations. The distinctive power of my human self is the ability to embody the moral principle of my specific nature so that the principle of my action is not outside me but comes from the heart of my being. In this way, I acquire autonomy and freedom and am able to preserve and nurture them by extending the horizon of moral care to the entire universe. Saying that “All things are already complete in me,” Mengzi endows the finite human mind with an infinite capacity for moral extension and elevation. Building on the Confucian teaching of ren and Mengzi’s theory of mind and nature, the Song-Ming era of Neo-Confucianism gradually brought to fruition the unification of the metaphysical plane of moral practice and the creative energy of the universe. Realizing my moral mind, I awaken myself to be one with the cosmos. Everything is in me, because by expanding the field of my concern and vigilance to the universe, I do not consider nothing external to myself. The authentic self redefines the idea of interiority as autonomy, that is, the capacity to embody the principle of being and acting and having nothing outside that can dictate or obstruct actions. Though posing moral practice as the culminating point of human endeavor, Mou recognizes the necessity and value of any epistemological effort, particularly scientific knowledge. The reason lies just in the fact that moral activity is spontaneously actualizing in the specificity of phenomena and circumstances. If even the smallest thing must not be forgotten or left out of the sphere of meaning, then cognitive activities are embedded in the circular movement of the moral mind. Facts and events that occur in the performative field have an objective aspect at their core. When moral action encounters difficulty in its scrupulous accomplishment, the mind should stop and analyze this obstacle as a thing contraposed to a knowing subject. The final aim is to restore the ever-flowing circular dynamism of the absolute mind. Eliminating any obstruction through apprehension of the objective thing is subordinated to the unavoidable task of the self. This temporary arrest and entrenchment in the horizontal multiplicity of things is called by Mou ziwo kanxian 自我坎陷that is, self-limitation of the moral self.

Full textAbstract:
Chapter 5 is devoted to the dynamism of self-limitation (ziwo kanxian 自我坎陷) of the moral self—that is, a paradoxical dynamism of entanglement that produces an ontological bifurcation between the moral self and cognitive self. From the viewpoint of the self, the question is how knowing, limited egos, scattered through the multiplicity of our brains and intentionally related to an exterior world, can be produced by an all-embracing and inexhaustible moral self, and ultimately contribute to its full realization. Now we have reached the key point of Mou’s definition of the human being as a “finite being that can become infinite.” My methodological proposal is to take advantage of the centrality of space and spatial metaphors in Mou’s thought. In Chapter 3, we outlined the hodological nature of jingjie, that is, the mental landscape shaped by our effort to reach and move through it. The word kanxian, which is difficult to translate, is employed by Mou to designate the self-limitation of the moral self, and is etymologically related to “sinking” and “descending.” Furthermore, Mou affirms that the knowing self is characterized by a “curved” or “twisting” thought. This suggests that the difference between absolute and finite selves is not representable as an abyss, a catastrophic fall without return, but as an inflection, a dynamism of descent that, in its curvature, allows the possibility of a recollection and an ascensional return to the straight level of the infinite mind. To unravel the paradox of self-limitation, we should bear in mind that any dynamism can be seen from two spatial viewpoints: that of the finite self, characterized by fragmentation and dialectical opposition, and that of the moral self, which transcends fixed separations through a circular dynamism that intersects the finite world only to elevate it to the origin and source of life. In addition to the topological interpretation, I think that another fruitful approach to the dynamism of “self-limitation” is represented by the Western-Chinese comparative approach. The reason is that Mou himself, in developing the idea of self-limitation in his later works, such as Phenomenon and Thing-in-Itself, or Intellectual Intuition and Chinese Philosophy, is constantly operating in a comparative way. In pursuing this cross-cultural contrast, I adopt the term kenosis as a frame of reference. The relevance of this concept, originally derived from theology, lies in the fact that it can indicate any process in which a higher metaphysical substance voluntarily renounces the fullness of its width and power to manifest and act on a lower plane. The first kenotic model is presented in Hegel’s Logic and Phenomenology of the Spirit: the dialectical unfolding of the Absolute that, passing through the travail of the negative, returns progressively to itself, discovering the truth of its absoluteness concealed in the beginning. The point of maximum similarity between the Hegelian approach and that of Mou lies in their shared conception of the Absolute as subjective—that is, as an organic unfolding of life that reflexively returns to itself. Analyzing the two ways of self-limitation in Hegel, that is, alienation (Entfremdung) and exteriorization (Entäusserung), I highlight the similarities between this kenotic movement and Mou’s ziwo kanxian. In both cases, the self is not given from the beginning but realizes itself in the process of becoming. This process of self-construction requires commitment and continuous mediation with concreteness, as well as the force to transcend every partial embodiment. However, two significant differences can be observed between the Hegel and Mou groups. The first is the different consideration of horizontal finite reality, which, in Hegel, does not possess any autonomous positivity but should be continuously annihilated and conserved only in his logical truth. In Mou, finite contingences are the places of manifestation and realization of the moral mind; thus, they possess a specific ontological and metaphysical value. The separation between the cognitive ego and the world as objects of knowledge is instituted only through attachment. This temporary and illusory division in the cognitive mind must be overcome, but the concreteness of any moment should be recovered through moral action. Hegel’s dialectical self develops on a purely cognitive level, and its longing for completeness is projected toward the final stage of the Absolute Spirit. In contrast, Mou’s moral self is accomplished at every instant through concern for other beings. The vertical axis of action intersects the horizontal axis of reality. The point of intersection between the verticality of moral endeavors and the horizontality of finite things is not to be found only at the end of the process, but is a fulfillment and a truth that can take place at any instant. The second kenotic model is offered by Emmanuel Lévinas’ (1906–1995) “philosophy of the Other” and is rooted in the kabbalistic idea of tzimtzum, that is, the voluntary self-withdrawal of God in order to free a void space in which the finite creature can autonomously consist and flourish. What appealed to Lévinas was the primacy of ethics, which seems to recall the basic tenet of Mou’s moral metaphysics. According to Lévinas, in my everyday life, I am immersed in the anonymity of being, enthralled by my search for enjoyment and self-fulfillment. The only event that can draw myself out of this circle of entrapment is the appearance of the face of another fellow human being who, in his vulnerability, draws me out of my horizon and calls me to my moral responsibility. I wake up from my selfish and dream-like plenitude only when I am attracted to this new barycenter, and I experience disruption and irreducible otherness. If we recall the Mencian example of the child about to fall in a well and the alarm and urgency shaking the roots of my being, we may notice here a common vital experience that is spontaneously produced by the appearance of the other. However, if we thoroughly analyze this experience, we may perceive a noticeable difference between Lévinas and Mou, which is based on a different idea of the self. In Lévinas, the subject is structurally centripetal and immersed in its egotistic jouissance; therefore, the disruption of radical otherness is required for me to be passively and forcibly drawn outside myself in the space of ethics. In contrast, in Mou, the human being may be immersed in the mind of habit and traverse his everyday world with the distraction of a somnambulist; however, the core of one’s being is the moral mind, which is always vigilant, living, and responsive. The innate moral consciousness that operates in my luminous core is a space for ethics. Despite the attempt to elaborate on metaphysics based on moral duty, Lévinas’ ethics remain at a cognitive level, that is, bound to an insuperable exteriority and distance between the finite self and the other. Mou’s self-limitation of the moral mind does not withdraw to let finite beings exist autonomously, as in the hypothesis of tzimtzum. Mou’s moral self accepts restraining itself, cognitively penetrating the phenomenal details of the world, and subsuming them in its action. In this way, the subject is able to fulfill its authentic nature, which is an infinite dynamic responsiveness to which nothing can be external.

The succession of the BK117 D-2 main rotor concept from the semi-rigid rotor to the BK117 D-3 bearingless main rotor (BMR) system, derived from the H135, held many new and innovative additional benefits in its wake. Although the H135 system is the best on the market regarding maintenance effort and maintenace cost (DMC), it was the purpose to push this benchmark even further. To achive additional benefits, three major improvements needed to be successfully implemented and none of them was a given. First to mention is the concept of the blade being separated in three parts. In case of foreign object damage (FOD), most of the time only the outer part needs to be repaired. In parallel a new possibility to fold the system with a full folding capacity was introduced with the challenge to realize the extremely low DMCs of the H135, in a decisively bigger helicopter and to benefit from the experience of millions of flight hours and thousands of helicopters operated throughout the world. Second a reduced flapping hinge offset was introduced to improve the comport of ride. The third point is the attachment bearing stress laminate providing the benefit of slim shape in the connection area between Flex control unit (FCU) and blade airfoil section. All this with the reduction of vibration in mind that results from changing a four-bladed rotor to a five-bladed one [1]. We were motivated to include also a, for such kind of critical part, new liquid infusion molding technology, to have all process parameters in our own hands, to make the production of blades more reliable and at the same time reduce the number of nonconformities by introducing more and more automation in production, which was enabled using the bearing laminate design of the attachment [2]. This innovative new design, in combination with a new manufacturing process introduced in a different production site under considerable time and cost pressure, needed the dedication of a multi-disciplinary transnational team, to finally overcome all deviations that became visible throughout the industrialization and/or prototype phase. This finally led to a mature serial production within a two years time frame. The paper is intended to highlight the often shortened and only briefly recognized period of preproduction, prototyping and the serialization and maturation of critical composite parts.

Abstract In this work, special (111) silicon stress test chips containing an array of piezoresistive sensor rosettes have been applied within 281-pin ceramic Pin Grid Array (PGA) packages. The test chips contained optimized eight element dual polarity rosettes, which are uniquely capable of evaluating the complete stress state at points on the surface of the die. Calibrated and characterized test chips were attached to the PGA packages using five high temperature die attachment adhesives designed for avionic applications. The adhesive systems included silver filled glasses, polyimide pastes, and thermoplastic films. The resistances of the sensors were recorded at room temperature before and after die attachment. The induced thermal stresses at sites on the die surface have been calculated using the measured resistance changes and piezoresistive theory. A comparison of the room temperature die stresses caused by the different die-attachment materials has been made. The stresses on the die surface after packaging were also characterized as a function of temperature. In addition, thermal aging and thermal cycling tests were conducted on the packages. The various die attachment materials were further evaluated by observing the changes in stress that occurred during these reliability tests. Finally, three-dimensional finite element simulations of the PGA packages were performed, and the stress predictions were correlated with the experimental test chip data.

Full textAbstract:
In our previous paper [1], we examined enhancing manipulation capabilities of cable robots by addition of base mobility to the spooling-winches. Base mobility facilitated the regulation of the tension-direction (via active repositioning of the mobile bases) and allowed for better conditioning of the wrench feasible workspace. In this paper, we explore design-modifications on the attachment to the common payload (merging multiple cables, attachment via pulleys) as alternate means to improve quality of the wrench-feasible workspace. Specifically we systematically examine the role played by attachment-modality and location, focusing on the benefits/drawbacks of the ensuing natural mechanical averaging behavior. Further, by using the notion of virtual cable subsystems, we illustrate the subsumption of this case into our previous mobile-cable-robot analysis framework. We seek improvement of the overall tension distribution by utilizing configuration space redundancy to shape the tension null-space. This is implemented computationally within the framework of a Tension Factor optimization problem over the workspace and explored via both simulation and experiments.

Full textAbstract:
The emergence of food-borne illness outbreaks linked to the contamination of fruits and vegetables is a great concern in industrialized countries. The current lack of control measures and effective sanitization methods prompt the need for new strategies to reduce contamination of produce. Our ability to assess the risk associated with produce contamination and to devise innovative control strategies depends on the identification of critical determinants that affect the growth and the persistence of human pathogens on plants. Salmonella enterica, a common causal agent of illness linked to produce, has the ability to colonize and persist on plants. Thus, our main objective was to identify plant-inducible genes that have a role in the growth and/or persistence of S. enterica on postharvest lettuce. Our findings suggest that in-vitro biofilm formation tests may provide a suitable model to predict the initial attachment of Salmonella to cut-romaine lettuce leaves and confirm that Salmonella could persist on lettuce during shelf-life storage. Importantly, we found that Salmonella association with lettuce increases its acid-tolerance, a trait which might be correlated with an enhanced ability of the pathogen to pass through the acidic barrier of the stomach. We have demonstrated that Salmonella can internalize leaves of iceberg lettuce through open stomata. We found for the first time that internalization is an active bacterial process mediated by chemotaxis and motility toward nutrient produced in the leaf by photosynthesis. These findings may provide a partial explanation for the failure of sanitizers to efficiently eradicate foodborne pathogens in leafy greens and may point to a novel mechanism utilized by foodborne and perhaps plant pathogens to colonize leaves. Using resolvase in vivo expression technology (RIVET) we have managed to identify multiple Salmonella genes, some of which with no assigned function, which are involved in attachment to and persistence of Salmonella on lettuce leaves. The precise function of these genes in Salmonella-leaf interactions is yet to be elucidated. Taken together, our findings have advanced the understanding of how Salmonella persist in the plant environment, as well as the potential consequences upon ingestion by human. The emerging knowledge opens new research directions which should ultimately be useful in developing new strategies and approaches to reduce leaf contamination and enhance the safety of fresh produce.

Full textAbstract:
Climate and hydrology are major drivers of ecosystems. They dramatically shape ecosystem structure and function, particularly in arid and semi-arid ecosystems. Understanding changes in climate, groundwater, and water quality and quantity is central to assessing the condition of park biota and key cultural resources. The Sonoran Desert Network collects data on climate, groundwater, and surface water at 11 National Park Service units in south-ern Arizona and New Mexico. This report provides an integrated look at climate, groundwater, and springs conditions at Saguaro National Park (NP) during water year 2019 (October 2018–September 2019). Annual rainfall in the Rincon Mountain District was 27.36" (69.49 cm) at the Mica Mountain RAWS station and 12.89" (32.74 cm) at the Desert Research Learning Center Davis station. February was the wettest month, accounting for nearly one-quarter of the annual rainfall at both stations. Each station recorded extreme precipitation events (>1") on three days. Mean monthly maximum and minimum air temperatures were 25.6°F (-3.6°C) and 78.1°F (25.6°C), respectively, at the Mica Mountain station, and 37.7°F (3.2°C) and 102.3°F (39.1°C), respectively, at the Desert Research Learning Center station. Overall temperatures in WY2019 were cooler than the mean for the entire record. The reconnaissance drought index for the Mica Mountain station indicated wetter conditions than average in WY2019. Both of the park’s NOAA COOP stations (one in each district) had large data gaps, partially due to the 35-day federal government shutdown in December and January. For this reason, climate conditions for the Tucson Mountain District are not reported. The mean groundwater level at well WSW-1 in WY2019 was higher than the mean for WY2018. The water level has generally been increasing since 2005, reflecting the continued aquifer recovery since the Central Avra Valley Storage and Recovery Project came online, recharging Central Arizona Project water. Water levels at the Red Hills well generally de-clined starting in fall WY2019, continuing through spring. Monsoon storms led to rapid water level increases. Peak water level occurred on September 18. The Madrona Pack Base well water level in WY2019 remained above 10 feet (3.05 m) below measuring point (bmp) in the fall and winter, followed by a steep decline starting in May and continuing until the end of September, when the water level rebounded following a three-day rain event. The high-est water level was recorded on February 15. Median water levels in the wells in the middle reach of Rincon Creek in WY2019 were higher than the medians for WY2018 (+0.18–0.68 ft/0.05–0.21 m), but still generally lower than 6.6 feet (2 m) bgs, the mean depth-to-water required to sustain juvenile cottonwood and willow trees. RC-7 was dry in June–September, and RC-4 was dry in only September. RC-5, RC-6 and Well 633106 did not go dry, and varied approximately 3–4 feet (1 m). Eleven springs were monitored in the Rincon Mountain District in WY2019. Most springs had relatively few indications of anthropogenic or natural disturbance. Anthropogenic disturbance included spring boxes or other modifications to flow. Examples of natural disturbance included game trails and scat. In addition, several sites exhibited slight disturbance from fires (e.g., burned woody debris and adjacent fire-scarred trees) and evidence of high-flow events. Crews observed 1–7 taxa of facultative/obligate wetland plants and 0–3 invasive non-native species at each spring. Across the springs, crews observed four non-native plant species: rose natal grass (Melinis repens), Kentucky bluegrass (Poa pratensis), crimson fountaingrass (Cenchrus setaceus), and red brome (Bromus rubens). Baseline data on water quality and chemistry were collected at all springs. It is likely that that all springs had surface water for at least some part of WY2019. However, temperature sensors to estimate surface water persistence failed...
