Full textAbstract:
In the current investigation, we modified the high Go low No-Go Sustained Attention to Response Task (SART) by replacing the single response on Go trials with a dual response (dual response SART or DR SART). In three experiments a total of 80 participants completed the SART and versions of the DR SART in which response probabilities varied from 50-50, through 70-30 to 90-10. The probability of No-Go withhold stimuli was .11 in all experiments. Using a dynamic utility based model proposed by Peebles and Bothell (2004) we predicted that the 50-50 DR-SART would dramatically reduce commission errors. Additionally, the model predicted that the probability of commission errors to be an increasing function of response frequency. Both predictions were confirmed. Although the increasing rate of commission errors with response probability can also be accommodated by the rationale originally proposed for the SART by its creators (Robertson, Manly, Andrade, Baddeley, & Yiend, 1997) the fact that the current DR SART results and SART findings in general can be accommodated by a utility model without need for any attention processes is a challenge to views that ascribe commission errors to lapses of sustained attention.

Full textAbstract:
Sedentary behaviors, such as leisure time computer use and sedentary video games, are significant barriers to regular physical activity and contribute to high rates of overweight and obesity among adolescents. Sedentary screen time can adversely affect food intake and food selection. Active video games may be a promising way of increasing daily physical activity levels among adolescents. Active video games may help modulate response inhibition and food intake. PURPOSE: Compare the effects of an acute bout of active and sedentary video gaming on N2 amplitudes (while viewing high calorie and low calorie images), Stroop Color Word Test (Stroop test) performance and ad libitum eating. METHODS: We used a within-subjects randomized crossover design with counterbalanced treatment conditions was used among 65 participants (31 girls, 34 boys; age = 13.5 ± 1.1 year; height = 161.4 ± 10.2 cm; weight = 52.5 ± 12.3 kg; BMI = 19.9 ± 3.3 kg·m2). Participants completed 2 separate video gaming sessions, 7 days apart, while energy expenditure during sedentary and active video game play was measured using the K4b2 portable metabolic system. The K4b2 system provided metabolic equivalents (METs) which are used as a measure of energy cost of physical activity. After either 60 minutes of active or sedentary video game play, participants completed a go/no-go task while viewing high calorie and low calorie images while electroencephalogram (EEG) data were collected. N2 event related potential (ERP) amplitudes were measured during the viewing task. Participants also completed a Stroop task to measure response inhibition. Finally, participants were given high calorie and low calorie snacks to consume ad libitum. We used a repeated measures ANOVA was used to measure main and interaction effects for N2 ERP amplitudes within subjects. RESULTS: Active video game play relative to sedentary video games significantly increased METs (F = 543.1, p ‰¤ 0.0001) from 1.7 ± 0.35 to 5.0 ± 1.2 METs. A significant gender-by-condition interaction (F = 7.03, p ‰¤ 0.009) was observed for energy expenditure with boys (5.4 ± 1.1 METs) expending more energy during the active video game than girls (4.5 ± 1.1 METs). No significant differences were observed for the N2 component (F = 0.50, p = 0.48) between video game conditions nor between genders (F = 1.85, p = 0.17). There were no significant differences (F = 3.10, p = 0.08) in the total number of calories consumed between the 2 video gaming conditions. Results from the Stroop task showed no significant differences for word naming (F = 0.45, p = 0.49), congruent condition (F = 0.43, p = 0.52) and incongruent condition (F = 0.14, p = 0.71) between the active and sedentary video games. CONCLUSION: Sixty minutes of active video gaming increases energy expenditure to a moderate intensity level but does not alter behavioral response or response inhibition to high calorie or low calorie foods.

Full textAbstract:
PURPOSE: To compare the effects of after-school sedentary versus active play on activation in the reward and cognitive control regions of the brain to pictures of high- and low-calorie foods. METHODS: 32 children (12 girls, 20 boys; age 8.7 ± 0.5 years; height 137.9 ± 6.9 cm; weight 32.4 ± 6.2 kg) participated in a randomized crossover study with counterbalanced treatment conditions. Conditions took place on separate days after school and included three hours of active or sedentary play. After each condition, neural activation in reward and cognitive control regions of the brain were assessed using functional magnetic resonance imaging (fMRI) while participants completed a go/no-go task involving pictures of high- and low-calorie foods. General response inhibition was measured by the Stroop task. Hunger was measured upon arrival to the testing facility and just prior to fMRI scans. Mixed effects models were used to evaluate main and interaction effects. RESULTS: Significant stimulus by condition interactions were found in the right superior parietal cortex, right postcentral gyrus and accumbens area (p <<> 0.05). High- versus low-calorie pictures of food elicited significantly different activation bilaterally in the orbitofrontal cortex (p <<> 0.01). Stroop task performance diminished significantly following the sedentary condition compared to the active condition (F = 6.79, p <<> 0.01). Subjective feelings of hunger were not different between conditions at any point. CONCLUSION: Sedentary behavior significantly decreased response inhibition and brain activation to pictures of high-calorie foods in areas of the brain important to the modulation of food intake. Decreased attention, reward, and response inhibition, following sedentary behavior, may contribute to disinhibited eating that can lead to overweight and obesity.

Smith, Veronica J. "Implicit Measurement of Racial Identity and Coping Responses to Racism in African Americans." Digital Archive @ GSU, 2006. http://digitalarchive.gsu.edu/psych_theses/20.
Full textAbstract:
African Americans’ experiences of racism have been found to be linked with higher levels of psychological distress. Coping responses to racism and racial identity may serve as moderators to this relationship. The present study uses an implicit measure to assess coping responses and racial identity. The main goal was to determine any correlation between implicit and explicit coping responses and racial identity, and between implicit coping responses to racism and explicit coping responses to general stress. A significant correlation was observed between implicit and explicit measures of coping responses and racial identity, and between implicit coping responses to racism and explicit coping responses to general stress. A significant correlation was also observed between implicit coping responses to racism and psychological distress. Findings indicate that implicit measures used in conjunction with explicit measures may provide a more comprehensive assessment of coping responses to racism and racial identity.

Full textAbstract:
Evidence suggests that slow paced diaphragmatic breathing (DB) can significantly affect prefrontal cortex functions through increasing an individual’s physiological self-regulatory capacity. The current research demonstrates the effects of paced DB on inhibitory control, which is considered to be a reliable measure of behavioral self-regulation. Eighty healthy participants were randomly assigned to one of two conditions (20 males and females each). Participants were instructed on either DB at a pace of six-breaths per minute (BPM) or instructions on environmental awareness and asked to breathe at 12 BPM. Following training, all participants completed a computer-based task designed to examine inhibitory processes. Physiological recordings of heart rate (HR), BPM, and HRV were collected at baseline, during the breathing training, during the cued go/no-go task, and after the cued go/no-go task. The findings demonstrated that the DB condition had significantly lower BPM, HR, and higher HRV (p’s<0.05) during active training than the environmental awareness condition. Furthermore, the DB condition performed significantly better on the measure of inhibition than the environmental awareness condition (p<0.05). The use of DB as a reliable method to increase physiological self-regulatory capacity and improve behavioral self-regulation, measured as inhibitory control, should continue to be explored.

Davies, Jessica Taylor. "The Effect of Time of Day of Chronic Exercise on Neural Response to Visual Food Cues." BYU ScholarsArchive, 2017. https://scholarsarchive.byu.edu/etd/6291.
Full textAbstract:
This study examined the effect of an 8-week, progressive exercise intervention on neural responses, specifically N2 amplitude as a measure of inhibitory control, to pictures of food. Healthy women ages 18-44 years were randomized to a morning (AM) exercise group or evening (PM) exercise group. The AM group did moderate-to-vigorous intensity exercise on 4 days per week between 6:30 and 9:30 a.m. while the PM group had the identical volume of exercise between 6:30 and 9:30 p.m. Neural responses, eating behaviors, cardiovascular fitness outcomes, and body weight/composition were measured at baseline and after the 8-week intervention. The N2 amplitude in response to pictures of high- and low-calorie foods was assessed using electroencephalography during a go/no-go task. Dietary restraint, emotional eating, and external eating were assessed using the Dutch Eating Behavior Questionnaire. VO2peak, HRmax, and time to completion were measured during a maximal treadmill test. Body weight was measured on a digital scale, and body composition was measured using dual-energy x-ray absorptiometry. There was not a significant task (go, no-go) × group (AM, PM) × period (baseline, 8 weeks) interaction (F = 0.18; p = 0.677), but there was a main effect of exercise over 8 weeks (F = 6.26; p = 0.017) with increased N2 amplitude following the intervention. There was not a significant interaction as a function of picture type (high-calorie, low-calorie), task, group, and period (F = 0.52; p = 0.478). Changes in body weight and neural outcomes were not significantly associated with changes in eating behaviors for either group (ps < 0.05). There was a significant group × period interaction for body weight (F = 4.90; p = 0.032). Body weight increased by 0.79 ± 1.16 kg in the AM group and decreased by 0.21 ± 1.46 kg in the PM group (effect size = 0.77; CI = 0.15-1.35). There was not a significant group × period interaction for body fat percentage, total body fat or fat-free mass (ps < 0.05). When examining the main effect of exercise on cardiovascular fitness outcomes, VO2peak was not different (F = 1.80; p = 0.187), time-to-completion on treadmill increased (F = 6.51; p = 0.014), and HRmax during the treadmill test was significantly lower (F = 5.49; p = 0.025). This study suggests that 8 weeks of exercise training may increase the inhibitory response to pictures of both high- and low-calorie foods. However, time of day of exercise did not influence this response. Eight weeks of exercise training did not change self-reported dietary restraint, external eating, or emotional eating, and there was no correlation between these eating behaviors and inhibitory control. However, evening exercise was more beneficial for body weight than morning exercise. Given the novelty of this study and its results, additional studies on the influence of time of day of exercise on weight management are needed.

Full textAbstract:
Physical Therapy<br>Ph.D.<br>Falls in older adults are linked with increased morbidity and mortality, and remain a major public health concern. Aging is associated with increased reliance on the visual system for postural control, termed “visual dependence”. Discordance between visual, vestibular and proprioceptive sensory information can lead to balance loss and falls. In addition to increased visual dependence (VD), older adults have more difficulty than younger adults in multi-tasking, performing simultaneous tasks (e.g. walk and talk), which may further increase fall risk. A common clinical test of physical function, the Timed Up and Go (TUG), requires the individual to stand from a seated position, walk forward, turn, walk back to the seat, turn and sit back down. Previous studies have explored the effect of multi-tasking during the TUG; however, the role of visual dependence and its interaction with multi-tasking on specific movement components of the TUG has not been deeply explored in the existing literature. The primary goal of this project was to understand the effects of aging and visual dependence on physical function as measured by the TUG. The three aims that guided this work are 1) to examine how aging affects performance metrics and movement components of the TUG (e.g. sit-to-stand, walking, turning, stand-to-sit) when simultaneously performing a motor task with or without with visual stimulation; 2) to examine how visual dependence affects performance metrics and movement components of the TUG when simultaneously performing a motor task with or without visual stimulation; and 3) to determine the effect of wearing a head mounted display (HMD) on performance metrics and movement components of the TUG in older and younger adults. Twelve younger adults (6 males) and sixteen older adults (8 males) participated in this work. They were further classified as sixteen visually independent adults (VI) (9 younger adults, 7 older adults, 9 males) and 12 visually dependent adults (VD) (3 young adults, 9 older adults, 5 males). Participants completed eight conditions: The dependent variables, measured using 6 inertial measurement unit sensors, included spatiotemporal variables of the TUG (total time, sub-component movement times, gait speed, step cadence during turning); three-dimensional peak trunk velocity (PTV) (i.e. around the mediolateral, vertical, and anteroposterior axes); acceleration range and jerk of sit-to-stand and stand-to-sit; and multitask cost. Multitask cost reflects the change in the motor behavior that occurs due to high attentional demanding conditions, with the lowest multitask cost reflecting poorer motor performance. The multitask cost was calculated as the percent change of each dependent variable in relation to the single task performance (i.e. TUG with no secondary task) in the third chapter. Our results demonstrated that the wear of HMD has an impact on TUG kinematics, regardless of adding a visual stimulus, more than holding a cup of water. Providing a visual stimulus decreased the PTV in walking and acceleration range in sit-to-stand. Particularly, presenting a visual stimulus in a pitch up rotation decreased the PTV in turning and increased the peak trunk velocity in stand-to-sit when compared to standard TUG. Older adults showed a decrease in the multitask cost (i.e. poorer performance) of turn and sit-to-stand time and the PTV in turning and a lower variability in trunk velocity in turning and sit-to-stand and the acceleration jerk in sit-to-stand and stand-to-sit compared to younger adults. Older adults who were visually dependent showed a lower mean and variability in the mediolateral and vertical acceleration range of sit-to-stand than older adults who were visually independent. Our results indicate that the wear of HMD has an impact on posture that should be taken into account in clinical research. Assessing the kinematics in turning and sitting-to-standing could be of a great interest for future studies that would include older adults with functional limitations (e.g. fallers versus non-fallers). Sit-to-stand motion, in particular, can differentiate older adults who are more sensitive to visual stimulation.<br>Temple University--Theses

Full textAbstract:
<p>Sarah Kane’s first play Blasted (1995) has often been read in a normative and biographical way by critics, authors and previous researchers. This essay makes a supplementary close reading of Blasted from gender and genealogical perspectives and utilizes theoretical works by Judith Butler, Luce Irigaray and Michel Foucault. My study makes clear that the characters different positions in language and talk create and maintain a power imbalance between them. Efforts to change and develop one’s individual position in language and talk are being made throughout the play since it is the only way to bring about a change in the social power structure. A fact that in turn also subsequently punishes those efforts. By analyzing the tools of representation, Kane points out a direct link between a violent power imbalance in a couples relationship and the violence of a war zone. In Blasted, it is revealed how violence in a private situation is mirrored in a situation of public violence and how the public violence, in turn, crawls back to the private zone and there repeats itself. By forcing one of the main characters to regress back to the infancy of language and from there alter the ability to act within the framework of human interrelations, Kane demonstrates how a change in social structures can be made, and as is shown in this essay, this indicates that a knowledge of how the social structures are being maintained and how they in turn can be disarranged, is what is required to create an opportunity for change.</p>

Full textAbstract:
This thesis attempted to examine the role of various task factors on children's group and individual learning on the balance beam: task presentation, task difficulty initial knowledge and physical feedback. Initially the literature is reviewed, there then follows a series of four empirical studies. The first empirical study examined if the mixed ability groups produced more learning then similar ability groups on Wilkening and Anderson's (1982) balance beam task. The study did not find the effect but it is suggested that this was due to the unsuitability of the task to the methodology used. The second study attempted to examine the effect on two levels of task difficulty on learning in groups on Sielger's (1976, 198) balance beam. It was found with higher difficulty task items the individual conditions, where children worked on their own, revealed less learning than the group work conditions, an effect that was found with the easier items. Also it was found that the children's pre-test classifications affected whether they advanced or not; the children with higher pre-test classifications showing less advancement. The third study attempted and succeeded in replicating this result. It also examined the verbal interactions between the children within the groupwork conditions. It was found that there was little relation between the dialogue within the interaction and the outcome in the post-test. The fourth study analysed the role of feedback in learning in the Sielger's balance beam, the children either worked on their own or in groups on the balance beam. They were given feedback on either all items or just the items that they performed poorly on the pre-test. It was found that the manipulation had only a slight effect on learning, but it was found that the pattern of learning across the three phases of the experiment was different for the group work conditions and the individual conditions. These findings are discussed in relation in other models and the role of the social situation is suggested.

Full textAbstract:
This paper introduces the results from a study on the distribution of heavy metals in chemical fractions in tidal sediment cores at four sample stations inside the baby clam breeding plain, inside the harvested clam breeding plain, and on the frontier between the plains in the clam farms in Tan Thanh commune, Go Cong Dong district, Tien Giang province, Vietnam. The partitioning of metals among the compartments of the sediment’s solid phase was investigated indirectly by selective sequential extraction of substances that are water-soluble, exchangeable, bound to carbonates, bound to Mn oxides, bound to amorphous Fe oxides, bound to crystalline Fe oxides, associated with organics and residual. In case of investigated heavy metals (HM), the concentrations of Zn and Hg exceeded the National Technical Regulation on Sediment Quality QCVN 43:2012/BTNMT by 1.12 - 3.53 times and 26.58 - 171.96 times, respectively. The highest HMs concentration was found in the oxidable fraction (more than 60%). The data demonstrates the important role of organic matters in the oxidable condition at the surficial sediment layer. Besides the oxidable fraction, high HMs concentrations were measured also in the residual fraction. The HMs content present in the solid residue also indicates the level of contamination in the river system: the greater the percentage of HMs present in the solid residue, the lesser the pollution in the environment because this solid residue involves components that can not be remobilized. The HMs concentrations depending on the depth of the sediment indicate that clam’s digestive activity or the decomposition of tissue and shell of clams possibly affects the content of HMs.<br>Bài báo giới thiệu các kết quả nghiên cứu về sự phân bố kim loại nặng dưới các dạng liên kết khác nhau trong các mẫu lõi trầm tích tại các bãi nuôi nghêu giống, bãi nuôi nghêu sau khi đã thu hoạch, và ranh giới giữa các bãi nuôi nghêu tại xã Tân Thành, huyện Gò Công Đông, tỉnh Tiền Giang, Việt Nam.

O trabalho objetivou analisar os fatores que influenciam a mobilização da atenção automática visual. Nas tarefas diárias, o Sistema Nervoso Central seleciona os estímulos mais relevantes para as tarefas. Para entender o quê influencia a mobilização atencional, conduzimos três experimentos com análise do tempo de reação a um estímulo vai em relação a um não-vai em voluntários humanos. Utilizamos um estímulo abrupto anterior ao aparecimento dos estímulos alvos para capturar a atenção automática na mesma posição ou na oposta ao aparecimento do estímulo alvo, para medir o efeito atencional. No 1º experimento, analisamos a influência da semelhança dos estímulos negativo e positivo e obtivemos o efeito atencional. Em seguida, pesquisamos a influência da semelhança do estímulo precedente com a do estímulo positivo e não encontramos evidências a respeito. Por último, verificamos como a estratégia atencional influencia no efeito atencional, mas não houve tal efeito. Concluímos que o fator crítico para a mobilização eficaz da atenção automática é a discriminabilidade entre os estímulos vai e não-vai.<br>This project investigated the important factors to mobilize the visual automatic attention. During our day, the Central Nervous System selects the most important stimulus to have a good performance in a task. For understanding which factors influence the attentional mobilization, we did three experiments analyzing the reaction time to a go stimuli comparing to a no go stimuli with human volunteers. We used an onset stimulus appearing before the go and no go stimuli at the same or at the opposite positions for having the attentional effect. At the first experiment, we researched the influence of go and no-go similarities and there was the attentional effect. Then, we investigated if the similarity between positive targets and cue is the critical factor but we didn\'t find the attentional effect. Finally, we checked the possibility of attentional effect to the CR by inducing the adoption of VL´s attentional set by volunteers, but there wasn\'t no effect. We concluded that the most important factor to an efficient mobilization of the automatic attention is the discriminability between the go and no-go stimuli.

Full textAbstract:
Part I studies the pre-independence developments in Mission, Ministry and Theological Education, commenting on the structures of theological education such as the Serampore College and United Theological College; the structures of coordination under the National Christian Council, the significance of national independence, church union and the Lindsay and Ranson studies. Part II deals with the developments in Indian Christian Theology and the theology of mission under the influence of indigenous theologians such as PD Devanandan, MM Thomas, the group of thinkers in the Christian Institute for the Study of Religion and Society and the Ecumenical Christian Centre, specially in the context of religious pluralism and poverty in India. It notes the cause and the concern of the polarising tendency of the conservative evangelicals and also the influences of the Western Christian structures. Part III studies the changing image of ministry itself and identifies the developments in ministry, formation of indigenous mission societies and parachurch ministries. Part IV journeys through select events and ventures that made significant contribution to lead theological education into relevant understanding of mission in India. It studies the Harrison Report on Theological Education in India, the attempts toward cooperation through the Board of Theological Education, the forming of one national structure for theological education in the Board of Theological Education on the Senate of Serampore College, and the national study of priorities in theological education. Part V studies the developments in the search for relevance in the Church of south India and in the theological education of its ministry as illustrated in the Tamilnadu Theological Seminary. The thesis concludes attesting that there is definite growth in relevance in Indian theological education, shaped both by lay and professional forces in the never ending search for relevance.

Full textAbstract:
Fetal alcohol spectrum disorders (FASDs) are a spectrum of disorders that occur due to prenatal alcohol exposure (PAE). Response inhibition refers to the ability to inhibit/suppress a prepotent behavioural tendency set in motion during an experimental task. Our research explored neocortical processing in heavy-exposed children from Cape Town, South Africa, performing the Go/NoGo response inhibition task. We utilised event-related electroencephalographic methodologies to examine event-related potentials (ERP) and eventrelated changes in induced oscillatory power - event-related desynchronisation (ERD)/eventrelated synchronisation (ERS). Across visual and auditory Go/NoGo tasks, we observed equivalent levels of inhibitory control between heavy-exposed (HE) participants and normally-developing controls; however, HEs demonstrated significantly slower reaction times relative to the control group. In an auditory ERP study, we observed a number of alcohol-related changes in ERP waveform morphology, such as decreased P2 amplitude, reduced P3 amplitude, and longer P3 peak latency. In addition, within the HE group, late in the trials, a slow-wave component was observed in both experimental conditions. A significant difference in N2 amplitude across conditions that has consistently been observed in normally-developing samples was not observed in the HE group. We extended previous research findings in the visual domain by analysing induced oscillatory responses. We observed within the normally-developing sample: (1) in both experimental conditions, a frontal induced beta-band ERS related to decision-making; and (2) in the NoGo-condition, a frontal gamma-band ERS related to cognitive-control. Within the HE group, the beta-ERS was not observed in either of the experimental conditions, neither was the gamma-ERS observed in the NoGo-condition. Frontal induced beta-power was predictive of performance accuracy in the HE group, but not in the control group. The observed alcohol-related effects were not explained and/or mediated by IQ (WISC-IQ), socio-economic circumstances, comorbid ADHD, or teratogenic effects related to postnatal lead exposure and prenatal cigarette-smoke exposure. Our results point to alterations in scalp-measured event-related neocortical oscillatory dynamics and slower processing of task demands due to heavy PAE. These alcohol-related effects are observable on ERP component measures, primarily related to conflict-monitoring and attention-based processing. PAE also affects induced classes of neocortical oscillatory dynamics related to decision-making and cognitive-control processes required to inhibit a prepotent motor-response.

Full textAbstract:
Introdução: o Diabetes Mellitus é uma epidemia mundial de incidência crescente e alta morbi-mortalidade. Apesar de a neuropatia diabética ser a complicação neurológica mais comum, é crescente o conhecimento de que existe um acometimento do sistema nervoso central, notadamente no que concerne às alterações cognitivas. Objetivos: investigar, por meio de duas tarefas cognitivas objetivas, simples, rápidas, de baixo
custo e de fácil aplicação, diferenças entre pacientes com Diabetes Mellitus Tipo 1 (DM1) e controles quanto a medidas de atenção e impulsividade, componentes-chave das funções executivas tradicionalmente avaliados por questionários subjetivos, longos, de difícil reprodutibilidade e que exigem psicólogos treinados; correlacionar as diferenças encontradas com características clínicas; explorar as correlações entre as duas tarefas. Métodos: Foram comparados os desempenhos de 20 pacientes com DM1 e 20 controles, de ambos os sexos, com idades entre 12 e 15 anos, utilizando a tarefa Agir-Não Agir e uma tarefa de Labirintos, e verificadas correlações entre eles. Resultados: o grupo DM1 teve mais respostas antecipatórias (RA) na tarefa Agir-Não Agir (p<0,05) e fez mais mudanças de trajetória nos Labirintos (p <0,01). Houve correlação entre hipoglicemias não-graves e RA (p=0,01), e entre hipoglicemias graves e número de toques nas paredes dos labirintos (p <0,05). HbA1c> 9% correlacionou-se com um maior número de becos sem saída nos labirintos (p <0,05). Os parâmetros mostraram-se coerentes dentro de cada tarefa e entre elas.
Conclusões: Encontramos indicadores de desatenção e impulsividade coexistindo no DM1, o primeiro estando mais relacionado à hiperglicemia, e o último à hipoglicemia. Investigações adicionais são necessárias para estudar o declínio cognitivo associado ao diabetes por meio de avaliações mais objetivas, e avaliar a confiabilidade e as propriedades psicométricas das tarefas aqui propostas.<br>Background : Diabetes Mellitus is a worldwide epidemic of increasing incidence and high morbidity and mortality. Although diabetic neuropathy is the most common neurological complication, the knowledge that there is an involvement of the central nervous system is increasing, especially in relation to cognitive changes. Aims: To investigate with two simple, inexpensive, rapid, objective and easy-to-apply tasks,
differences between patients with Type 1 Diabetes Mellitus (T1DM) and controls in outcome measures of attention and impulsivity, key-executive function components traditionally assessed by subjective and long questionnaires of difficult reproducibility that require trained psychologists; to correlate the alterations with clinical characteristics; to explore correlations between the tasks. Methods: We compared the scores of 20 T1DM to 20 controls, both sexes, aged 12 to 15 years, using a Go-NoGo and a Maze task, and verified correlations between them. Results: T1DM group had more anticipatory answers (AA) in Go-NoGo task (p<0,05) and made more direction changes in Mazes (p<0,01). There was correlation between non-severe
hypoglycaemias and AA (p=0,01), and between severe hypoglycaemias and number of touches in Mazes’ walls (p<0,05). HbA1c>9% correlated to a greater number of alleys in Mazes (p<0,05). The tasks’ parameters were coherent among each task and between them. Conclusions: We found indicators of inattention and impulsivity coexisting in T1DM, the first more related to hyperglycaemia and the later to hypoglycemia. Further research is needed to study diabetes-associated cognitive decline with more objective parameters and evaluate the reliability and psychometric properties of the tasks herein proposed.<br>Dissertação (Mestrado)

Full textAbstract:
The purpose of this thesis was to explore the potential of near-infrared spectroscopy (NIRS) as an access channel by establishing reliable signal detection to verify the existence of signal differences associated with changes in activity. This thesis focused on using NIRS to measure brain activity from the prefrontal cortex during an auditory Go-No-Go task. A singular spectrum analysis change-point detection algorithm was applied to identify transition points where the NIRS signal properties varied from previous data points in the signal, indicating a change in brain activity. With this algorithm, latency values for change-points detected ranged from 6.44 s to 9.34 s. The averaged positive predictive values over all runs were modest (from 49.41% to 67.73%), with the corresponding negative predictive values being generally higher (48.66% to 78.80%). However, positive and negative predictive values up to 97.22% and 95.14%, respectively, were achieved for individual runs. No hemispheric differences were found.

Since the beginning of the 2000s, Mixed Martial Arts (MMA) and, more specifically, the Ultimate Fighting Championship organization (UFC), have been experiencing exponential growth. In recent years, there have been some differences in what fans want to see, having fights with a lot of drama between the fighters generates large numbers of pay per view compared to fights between highly technical and dominant fighters, even if they are title fights. The purpose of our study is to understand if trash-talk between the fighters before the fight tends to attract more fans to the sport and what kind of sentiments does it generate in them. We extracted tweets from fans and answers from fighters and cross these data. We found that fights involving a lot of drama between the fighters are the ones that have the biggest pay per view numbers, 2 of them generating 2.5 times more pay per view than 7 fights between lower profile fighters. However, we did not find a direct influence of each fighter’s negative expressions used during the conference and the fans’ tweets but, we did find that the context of the event in itself plays a more significant role as the rivalry between fighters is expressed during the press conference. Regarding the engagement of fans’, while we found no evidence of a cause-effect relationship with the negative sentiment of the fighters, we confirmed that higher levels of profanity speech are associated with higher engagement, both on pay-per-view and on the number of tweets.<br>Desde o início dos anos 2000, as Artes Marciais Mistas (MMA) e, mais especificamente, a organização Ultimate Fighting Championship (UFC), têm tido um crescimento exponencial. Nos últimos anos, parece haver algumas diferenças no que os fãs querem ver, tendo combates que envolvem muito drama entre os lutadores gerado números de pay per view muito maiores do que combates entre lutadores altamente técnicos e dominantes, mesmo sendo estes combates pelo título. O objetivo do nosso estudo é entender se o trash-talk entre os lutadores antes da luta tende a atrair mais fãs para o desporto e que tipo de sentimentos provoca nestes fãs. Extraímos tweets dos fãs e respostas dos lutadores e cruzámos a informação. Os resultados mostram que os combates que envolvem muito drama entre os lutadores são os que têm os maiores números de pay per view, gerando 2 deles 2,5 vezes mais pay per view do que 7 combates entre lutadores com um perfil mais discreto. No entanto, não encontrámos uma influência direta das expressões negativas dos lutador nas conferência nos tweets dos seus fãs, mas descobrimos que o contexto do evento em si desempenha um papel mais significativo, pois a rivalidade entre os lutadores é expressa durante a conferência de imprensa do evento. Em relação ao envolvimento dos fãs, embora não tenhamos encontrado evidências de uma relação de causa-efeito com o sentimento negativo dos lutadores, verificámos que níveis mais altos de palavrões estão associados a um maior envolvimento, tanto no pay-per-view como no número de tweets.

Full textAbstract:
Under frameworks such as Alcohol Myopia Theory, a body of literature has developed demonstrating how alcohol intoxication can increase behavioral risk-taking, potentially via impaired inhibition of prepotent behavioral responses. A separate area of research has shown that responses to alcohol intoxication are not homogenous across the population. Whereas most previous research has considered alcohol responses in relation to risk for alcohol use disorders, the present investigation tested whether they may additionally contribute to the acute effects of alcohol on drinking-episode-specific cognitive and behavioral consequences. We recruited 82 moderate-to-heavy drinking emerging adults to each complete 2 research protocols: a placebo-controlled, within-subject, counterbalanced alcohol challenge in a simulated bar laboratory and a 21-day, event-level self-monitoring follow-up. Replicating previous research, the alcohol challenge increased heart rate and subjective stimulant-like and sedative-like responses and impaired psychomotor performance and response inhibition. Individual differences in subjective stimulation but not sedation were significantly associated with inhibitory impairment. In the event-level follow-up, we found little evidence that alcohol responses elevated risk for adverse behavioral outcomes, although evidence was stronger that alcohol responses were associated with alcohol-induced memory blackout. Whether and how alcohol responses relate to the physiological, cognitive, and behavioral consequences of alcohol intoxication may depend on a) the quality of the response (e.g., stimulation vs. sedation), b) the type of outcome (e.g., response inhibition vs. blackout vs. behavioral risk-taking), and c) whether perceptions of alcohol-induced effects may contribute to emerging adults' evaluations of risk (e.g., driving after drinking and riding with a drinking driver).<br>text

This piece is launched between 2003 to 2007 in various parts of the world, including South Korea, Taiwan, France, and Italy. It is also one of the most complex, cross media and interdisciplinary piece in Tang’s entire artistic creation. Concentrating on I Go Traveling V / A Postcard with Scenery”, I try to analyze the multiple layers of this action piece, how it is proceeded, its complicated creative process, and how its meaning is operated in different levels, visible and imaginative. In addition, this artwork is stimulated by an old image “Winter beach” from 1970’s. I will also examine its cultural context and the making of it by artist’s image-memories, upon which “I Go Traveling V / A Postcard with Scenery”is fundamentally based. In the end, I will present the motivation of the artist, the migration of this photo image, and the allegorical meanings of this artwork.

Full textAbstract:
The aim of this study is to assess the multi-disciplinary approach in the investigation of corruption in the South African public service. Data was collected by means of in-depth interviews conducted with members of the Directorate for Priority Crime Investigation’s Anti-Corruption Task Team to gain a comprehensive understanding of their experiences regarding the effectiveness of the Anti-Corruption Task Team in the investigation of corruption within the public service. In addition, the researcher conducted a comprehensive literature study of local and international legislation to curb corruption, supplemented with various multi-disciplinary approaches employed internationally. Furthermore, various global Anti-Corruption Agencies were studied to comprehend their functions and efficacy.
The findings of the research identified and described various impediments facing the Anti-Corruption Task Team’s effectiveness in investigating corruption within the public service. As a result, this study recommends the need to establish a single Anti-Corruption Agency with a comprehensive mandate to prevent, investigate, and educate on corruption, to critically safeguard the independence of the Anti-Corruption Task Team against political interference, as well as the allocation of adequate resources and budget for its effective operation.
The research identified best practices globally to combat corruption, which can be used to amend the current anti-corruption practices to suit the South African public service. Consequently, this study contributes significantly towards effective anti-corruption investigation in the South African public service.<br>Maikemišetšo a dinyakišišo tše ke go lekola mokgwa wa go kopanya dikarolo tše mmalwa tša thuto go nyakišiša bomenetša ka ditirelong tša setšhaba tša Afrika Borwa.

<div>Advancements in virtual reality (VR) technologies have led to overwhelming critique and acclaim in recent years. Academic researchers have already begun to take advantage of these immersive technologies across all manner of settings. Using immersive technologies, educators are able to more easily interpret complex information with students and colleagues. Despite the advantages these technologies bring, some drawbacks still remain. One particular drawback is the difficulty of engaging in immersive environments with others in a shared physical space (i.e., with a shared virtual environment). A common strategy for improving collaborative data exploration has been to use technological substitutions to make distant users feel they are collaborating in the same space. This research, however, is focused on how virtual reality can be used to build upon real-world interactions which take place in the same physical space (i.e., collaborative, co-located, multi-user virtual reality).</div><div><br></div><div>In this study we address two primary dimensions of collaborative data visualization and analysis as follows: [1] we detail the implementation of a novel co-located VR hardware and software system, [2] we conduct a formal user experience study of the novel system using the NASA Task Load Index (Hart, 1986) and introduce the Modified User Experience Inventory, a new user study inventory based upon the Unified User Experience Inventory, (Tcha-Tokey, Christmann, Loup-Escande, Richir, 2016) to empirically observe the dependent measures of Workload, Presence, Engagement, Consequence, and Immersion. A total of 77 participants volunteered to join a demonstration of this technology at Purdue University. In groups ranging from two to four, participants shared a co-located virtual environment built to visualize point cloud measurements of exploded supernovae. This study is not experimental but observational. We found there to be moderately high levels of user experience and moderate levels of workload demand in our results. We describe the implementation of the software platform and present user reactions to the technology that was created. These are described in detail within this manuscript.</div>
