The Mediation of Athlete Satisfaction on the Relationship of Role Dimensions and Team Commitment

In the industrial and organizational domain, an individual’s commitment to an organization can be influenced by the perceived satisfaction with their work experience (Meyer & Allen, 1991; Porter et al., 1974). Moreover, previous research has demonstrated role components, specifically role stressors (i.e., role ambiguity, role conflict, role overload) as antecedents of commitment (Mathieu & Zajac, 1990; Meyer et al., 2002; Mowday et al., 1982). Correspondingly, it has been demonstrated that role components may impact an individual’s satisfaction. Specifically, role ambiguity and role satisfaction have been exhibited to be significant correlates of athlete satisfaction (Eys et al., 2003; Jones, 2006). Although these constructs have been studied separately, the literature has yet to examine them concurrently. The purpose of the current study was to examine the degree to which athlete satisfaction mediates the relationship between role dimensions and team commitment in collegiate athletes. It was hypothesized that with athlete satisfaction as a significant mediator, role conflict and role ambiguity will negatively predict team commitment, while role acceptance and role satisfaction will positively predict team commitment. However, these results indicated that no significant mediations were established based on these hypotheses. Therefore, regressions were run on significant correlations with team commitment. The results demonstrated that role conflict, team task contribution, and team social contribution were significant predictors of team commitment.

Analysis of tandem queues with finite buffer capacity

ABSTRACT Tandem queues with finite buffer capacity commonly exist in practical applications. By viewing a tandem queue as an integrated system, an innovative approach has been developed to analyze its performance through insight from Friedman's reduction method. In our approach, the starvation at the bottleneck caused by service time randomness is modeled by interruptions. Fundamental properties of tandem queues with finite buffer capacity are examined. Without the assumptions of phase-type distributions and stochastic independence, we show that, in general, the system service rate of a tandem queue with a finite buffer capacity is equal to or smaller than its bottleneck service rate, and virtual interruptions, which are the extra idle period at the bottleneck caused by the non-bottlenecks, depend on arrival rates. Hence, the system service rate is a function of arrival rates when the buffer capacity of a tandem queue is finite. Approximations for the mean queue time of a dual tandem queue are developed using the concept of virtual interruptions.
The Ethics of Making Risky Decisions for Others

Utilitarianism, it has been said, is not sensitive to the distribution of welfare. In making risky decisions for others there are multiple sensitivities at work. I present examples of risky decision-making involving drug allocations, charitable giving, breast-cancer screening and Caesarian sections. In each of these examples there is a different sensitivity at work that pulls away from the utilitarian prescription. Instances of saving fewer people at a greater risk to many is more complex because there are two distributional sensitivities at work that pull in opposite directions from the utilitarian calculus. I discuss objections to these sensitivities and conclude with some reflections on the value of formal modeling in thinking about societal risk.
A qualitative exploration of the unique barriers, challenges and experiences encountered by undergraduate psychology students with mental health problems

ABSTRACT Research demonstrating student mental distress typically focuses on mental wellbeing by combining questionnaire responses from students studying a variety of disciplines [see Ibrahim, A. K. , S. J. Kelly, C. E. Adams, and C. Glazebrook. 2013. “A Systematic Review of Studies of Depression Prevalence in University Students. ” Journal of Psychiatric Research 47 (3): 391–400; Bewick, B. , G. Koutsopoulou, J. Miles, E. Slaa, and M. Barkham. 2010. “Changes in Undergraduate Students’ Psychological Well-being as they Progress Through University. ” Studies in Higher Education 35 (6): 633–645]. Little is known about how student mental health varies as a function of degree type. Psychology students are of interest here, as Psychology is one of few degrees where mental health is a topic of study. Semi-structured interviews were conducted with 20 undergraduate psychology students with mental health difficulties from a UK University. Thematic analysis showed that previous mental health problems were a motivator for studying psychology. The delivery of taught mental health content exacerbated pre-existing symptoms, induced concern and challenged perceptions of treatments. Students also experienced unique challenges when accessing a variety of University support networks. Findings can be used to inform policy changes to improve these students’ university experiences.
Measuring Populism across Nations: Testing for Measurement Invariance of an Inventory of Populist Attitudes

The rising voter support for populist parties in Western Democracies in recent years has incited academic interest in populist voters and attitudes connected to the voting propensity of populist actors. In line of this research, numerous scales to measure populist attitudes among voters have been proposed. In most cases, however, the measurement of populist attitudes was tailored to specific countries and its applicability to cross-national research on populism was not assessed. This article uses a cross-national survey to assess the measurement invariance, reliability, and validity of a deductively developed inventory for populist attitudes. The findings suggest that there is a common attitudinal base to left- and right-wing populism which may be measured reliably and invariantly across nations.
Long-term use of pitolisant to treat patients with narcolepsy: Harmony III Study

Abstract Study Objectives To asses the long-term safety and efficacy of pitolisant, an histamine H3-receptor antagonist, on narcolepsy. Methods This open-label, single-arm, pragmatic study, recruited adult patients with narcolepsy and Epworth Sleepiness Scale (ESS) score ≥12. After a titration period, patients were treated for up to 1 year with oral pitolisant once-a-day at up to 40 mg. Concomitant stimulants and anti-cataplectic agents were allowed. The primary endpoint was safety; secondary endpoints included ESS, cataplexy, and other diary parameters. Results Patients (n = 102, 75 with cataplexy) received pitolisant, for the first time in 73 of them. Sixty-eight patients (51 with cataplexy) completed the 12-month treatment. Common treatment-emergent adverse events were headache (11.8% of patients), insomnia (8.8%), weight gain (7.8%), anxiety (6.9%), depressive symptoms (4.9%), and nausea (4.9%). Seven patients had a serious adverse effect, unrelated to pitolisant except for a possibly related miscarriage. One-third of patients stopped pitolisant, mostly (19.6%) for insufficient benefit. ESS score decreased by 4.6 ± 0.6. Two-thirds of patients completing the treatment were responders (ESS ≤ 10 or ESS decrease ≥ 3), and one third had normalized ESS (≤10). Complete and partial cataplexy, hallucinations, sleep paralysis, and sleep attacks were reduced by 76%, 65%, 54%, 63%, and 27%, respectively. Pitolisant as monotherapy (43% of patients) was better tolerated and more efficacious on ESS than on add-on, but efficacy was maintained in this last case. Conclusions Long-term safety and efficacy of pitolisant on daytime sleepiness, cataplexy, hallucinations, and sleep paralysis is confirmed.
A LASSO-Based Method for Detecting Item-Trait Patterns of Replenished Items in Multidimensional Computerized Adaptive Testing

Multidimensional computerized adaptive testing (MCAT) is one of the widely discussed topics in psychometrics. Within the context of item replenishment in MCAT, it is important to identify the item-trait pattern for each replenished item, which indicates the set of the latent traits that are measured by each replenished item in the item pool. We propose a pattern recognition method based on the least absolute shrinkage and selection operator (LASSO) to detect the optimal item-trait patterns of the replenished items via an MCAT test. Simulation studies are conducted to investigate the performance of the proposed method in pattern recognition accuracy under different conditions across various latent trait correlation, item discrimination, test lengths, and item selection criteria in the test. Results show that the proposed method can accurately and efficiently identify the item-trait patterns of the replenished items in both the two-dimensional and three-dimensional item pools.
Forever Slaves? Inequality, Uncleanliness and Vigilance about Origins in the Southern Highlands of Madagascar

ABSTRACT In the southern highlands of Madagascar, Betsileo free descendants strictly avoid marrying descendants of slaves, whom they regard as ‘unclean people’. A close examination of the history of a slave descent group shows that the most serious difficulty faced by former slaves after abolition was not access to land but ritual uncleanliness, which prevented intermarriage with free people and led to the essentialisation of the now pervasive hierarchical distinction between clean and unclean people. Today, free descendants actively maintain a social memory of ‘origins’ and remain extremely vigilant about not marrying the slave descendants, who are ‘locked’ into an unequal and unclean status that they cannot easily escape.
Evolving identities: exploring leaders’ positioning in the birth of a professional literacy collaboration

ABSTRACT This qualitative investigation used positioning theory and discourse analysis as tools to explore the evolution of the first year of a leadership team partnership between a group of university researchers and the leaders of a private non-profit literacy agency (hereafter referred to as Private Literacy Agency). The central goal of this university/Private Literacy Agency team was to provide quality literacy professional development to the teachers at the Private Literacy Agency. Results reveal the complex and nuanced nature of the evolution of the leadership team partnership across three trimesters of the first year of the project. This work contributes to the literature in two important ways. First, much of the literature on PD initiatives reports the positive outcomes of highly adaptive PD endeavours but does not include a nuanced and close-up look at process by which such endeavours evolve addressing both the difficulties and successes throughout the process. Our work addresses this concern. Second, much of the existing PD research focuses on teachers’ participation in professional learning groups with little attention to the roles that leaders in institutions play in the structure, design and enactment of such learning groups at the broader institutional level. Our work fills this gap in the literature.
The Nature of Unconscious Attention to Subliminal Cues

Attentional selection in humans is mostly determined by what is important to them or by the saliency of the objects around them. How our visual and attentional system manage these various sources of attentional capture is one of the most intensely debated issues in cognitive psychology. Along with the traditional dichotomy of goal-driven and stimulus-driven theories, newer frameworks such as reward learning and selection history have been proposed as well to understand how a stimulus captures attention. However, surprisingly little is known about the different forms of attentional control by information that is not consciously accessible to us. In this article, we will review several studies that have examined attentional capture by subliminal cues. We will specifically focus on spatial cuing studies that have shown through response times and eye movements that subliminal cues can affect attentional selection. A majority of these studies have argued that attentional capture by subliminal cues is entirely automatic and stimulus-driven. We will evaluate their claims of automaticity and contrast them with a few other studies that have suggested that orienting to unconscious cues proceeds in a manner that is contingent with the top-down goals of the individual. Resolving this debate has consequences for understanding the depths and the limits of unconscious processing. It has implications for general theories of attentional selection as well. In this review, we aim to provide the current status of research in this domain and point out open questions and future directions.
Tourism and Foreign Direct Investment Inflows in Sri Lanka

This article examines the relationship between tourism and foreign direct investment (FDI) and the factors that enhance tourism in Sri Lanka using data over the years 1978–2015, under a vector autoregressive framework. The results reveal that there is a significant long-run equilibrium relationship between tourism, and a number of variables such as FDI, exchange rate, tourism price and civil war of the country. The results also reveal that there exist unidirectional causal relationships from FDI to tourism and tourism price to tourism, in both the long run and the short run. In light of this finding, it is recommended that Sri Lanka should introduce policies that would increase FDI inflows into the tourism industry and maintain a competitive tourism price to attract more tourist arrivals.

Priority switching scheduler

We define a novel core network router scheduling architecture called priority switching scheduler (PSS), to carry and isolate time constrained and elastic traffic flows from best‐effort traffic. To date, one possible solution has been to implement a core DiffServ network with standard fair queuing and scheduling mechanisms as proposed in the well‐known “A Differentiated Services Code Point (DSCP) for Capacity‐Admitted Traffic” from RFC5865. This architecture is one of the most selected solutions by internet service provider for access networks (e.g., customer‐premises equipment) and deployed within several performance‐enhancing proxies (PEPs) over satellite communications (SATCOM) architectures. In this study, we argue that the proposed standard implementation does not allow to efficiently quantify the reserved capacity for the AF class. By using a novel credit‐based shaper mechanism called burst limiting shaper (BLS) to manage the AF class, we show that PSS can provide the same isolation for the time constrained EF class while better quantifying the part allocated to the AF class. PSS operates both when the output link capacity is fixed (e.g., wire links and terrestrial networks) or might vary due to system impairments or weather condition (e.g., wireless or satellite links). We demonstrate the capability of PSS through an emulated SATCOM scenario with variable capacity and show the AF output rate is less dependent on the EF traffic, which improves the quantification of the reserved capacity of AF, without impacting EF traffic.
Income Dynamics, Economic Rents, and the Financialization of the U.S. Economy

The 2008 collapse of the world financial system, while proximately linked to the housing bubble and risk-laden mortgage backed securities, was a consequence of the financialization of the U.S. economy since the 1970s. This article examines the institutional and income dynamics associated with the financialization of the U.S. economy, advancing a sociological explanation of income shifts into the finance sector. Complementary developments include banking deregulation, finance industry concentration, increased size and scope of institutional investors, the shareholder value movement, and dominance of the neoliberal policy model. As a result, we estimate that between 5.8 and 6.6 trillion dollars were transferred to the finance sector since 1980. We conclude that understanding inequality dynamics requires attention to market institutions and politics.
Automatic generation and evaluation of recombination games

Many new board games are designed each year, ranging from the unplayable to the truly exceptional. For each successful design there are untold numbers of failures; game design is something of an art. Players generally agree on some basic properties that indicate the quality and viability of a game, however these properties have remained subjective and open to interpretation. The aims of this thesis are to determine whether such quality criteria may be precisely defined and automatically measured through self-play in order to estimate the likelihood that a given game will be of interest to human players, and whether this information may be used to direct an automated search for new games of high quality. Combinatorial games provide an excellent test bed for this purpose as they are typically deep yet described by simple welldefined rule sets. To test these ideas, a game description language was devised to express such games and a general game system implemented to play, measure and explore them. Key features of the system include modules for measuring statistical aspects of self-play and synthesising new games through the evolution of existing rule sets. Experiments were conducted to determine whether automated game measurements correlate with rankings of games by human players, and whether such correlations could be used to inform the automated search for new high quality games. The results support both hypotheses and demonstrate the emergence of interesting new rule combinations.
A Preliminary Study of Mental Health and Wellness in the Veterinary Field in Pinellas County Florida

The suicide rate for veterinarians has been steadily increasing over the last half-century, both across America and the world. However, there is a lack of awareness in the veterinary field regarding this issue as well as what increases veterinarians risk for suicidal ideation. The purpose of this study was to examine what work-related stressors are most common and most influential in the field of veterinary medicine in order to understand the underlying causes of the increased suicide rate among veterinarians. A Qualtrics© made questionnaire was sent through email messaging to 107 Pinellas County veterinarians from September 17 to October 22, 2018. Personal information that would allow for identification of responses, including IP addresses, was excluded in order to maintain anonymity. The survey included demographics questions sampling gender, race, age, years practicing, location of practice, position in the veterinary field, and type of veterinary medicine being practiced. The questionnaire also asked about job satisfaction, future occupational plans, occupational influence on mental health, and awareness of mental health in the veterinary field. Participants ranked stressors known to increase susceptibility to suicidal ideation on a 1-7 Likert Scale from two perspectives: on prevalence in the veterinary field, and on the effect that each professional stressor had on their personal health. The most influential stressors on the respondents’ personal health were found to be client complaints and client expectations, which were also ranked 3rd and 4th in prevalence in the field. This suggests client relations are one of the major stressors in the veterinary field and could be prominent in the increasing suicide rate. Occupational burnout, demands of the practice, and practice management responsibilities were also highly ranked in both prevalence and influence. However, familiarity with euthanasia was ranked 8th in prevalence and 12th in influence, thus suggesting familiarity with euthanasia has very little effect on the mental health of veterinarians.
Does Paternal Involvement in Childcare Influence Mothers’ Employment Trajectories during the Early Stages of Parenthood in the UK?

Understanding the conditions that facilitate mothers’ employment and fathers’ involvement in childcare and housework is important for achieving gender equity in paid and unpaid work. Using Sen’s capabilities framework, the article explores the effect of paternal involvement in childcare on mothers’ employment resumption nine months and three years’ post-childbirth. Logistic regression is used on the UK’s Millennium Cohort Study. Results show that the probability of mothers resuming employment increase at both time points if the father is more involved in childcare nine months post-birth – and in some cases, this is more important for her employment resumption than her occupational class and the number of hours the father spends in paid work. However, attitudes have an even stronger effect, and appear to drive behaviour, as the probability of mothers resuming employment increase significantly three years post-birth if either parent endorses more gender egalitarian roles in the first year of parenthood.
Design Interventions for Promoting the Mental Health of Young Academics

It is essential to graduate students to contribute researching in their academic field. Although it leads to the success of academic career path, the students are more at high risk of mental health problems. Thus, this study attempted to reveal underlying causes of the problems, figure out coping techniques and explore design interventions that can improve of graduate students’ mental health quality. We conducted interviews with one health professional expert and twenty-five graduate students. Design Sheet was created to elicit design solution ideas and distributed to ten professional designers. From the research, we have found out that graduate students are suffering from multiple reasons however there are unmet mental health needs among graduate students. By the end of the paper, we propose five design guidelines for designers to make products or services to promote mental health of graduate students.
