Cognitive appraisal of dissertation stress among undergraduate students

The present study examined changes in primary and secondary appraisal, and coping strategies utilized in the final weeks leading to dissertation submission. Sixty volunteer Sports Studies dissertation students (male: n = 29; female: n = 31) completed an adapted Cognitive Appraisal of Health Scale (CAHS: Kessler, 1998), and Brief COPE (Carver, Scheier, & Weintraub, 1989) on 4 occasions over the 6 weeks before dissertation submission. Repeated measures multivariate analysis of variance indicated a significant main effect for gender, with no main effect for changes over time and no significant interaction effect. Results demonstrated that males perceived the dissertation to be significantly more threatening and iess challenging than females. With regard to coping, males used more active coping, positive reframing, planning, and acceptance of the stressor, with lower scores for self-blame, venting of emotions, and behavioral disengagement. The results suggest that, for this student population, the dissertation did not become increasingly stressful in the period before submission. Clear relationships were also evidenced between primary appraisal, secondary appraisal, and coping. Future research should seek to identify factors that moderate the influence of situational stressors on coping responses among undergraduate students

Beyond the technical: The role of emotion regulation in lacrosse officiating.

Emotions can influence the performance of referees leading to a need to examine emotions experienced, and regulation strategies used by referees. The present study assessed emotions and emotion regulation strategies of 19 referees officiating at an Under-19 Lacrosse World Championship. Using survey methods and focus group interviews, officials responded to five questions: (a) What emotions were experienced? (b) What events elicited emotions? (c) How did lacrosse officials manage their own emotional states prior to, throughout, and following a competitive game? (d) How did officials manage others' emotional states? (e) What were the perceived consequences of these strategies? Results indicate that emotions fluctuated throughout the tournament as referees encountered intrapersonal and interpersonal emotion-eliciting events. These fluctuations are suggested to come from a progressively diminished capacity for emotion regulation. Participants used emotion regulation strategies that could be classified into Gross' (1999) families of emotion regulation strategies, often relying on suppression, emotion contagion, and preventative refereeing. Collectively, the results offer new insights into referee emotion regulation at international events

Inconsistency of decision-making, the Achilles heel of referees

This is an accepted manuscript of an article published by Taylor & Francis in Journal of Sports Sciences on 12/12/2016, available online: https://doi.org/10.1080/02640414.2016.1265143 The accepted version of the publication may differ from the final published version.This study assessed whether decisions made by six qualified referees were consistent when watching the live 2016 televised Champions League Final. Referees were paired off into three separate rooms. Two referees watched the game with no supporters present. Two watched the game surrounded by Real Madrid supporters, and the remaining two watched the game surrounded by Athletic Madrid supporters. Referees were asked to decide whether each decision made by the on-field referee was either correct or incorrect. Results identified two types of refereeing inconsistency. The first type was a systematic tendency of the supporting crowds (both rooms) to influence the adjudicating referees to make fewer incorrect (disagree with the on-field referee) decisions (8 and 5) than referees in the “no supporters” room (19) (χ2 = 11.22 [df = 2], P = 0.004). The second type of inconsistency was the home advantage “bias”, where the surrounding crowd influenced the adjudicating referees to favour their team, by disagreeing with the decision made by the on-field referee (χ2 = 6.0 [df = 2], P = 0.0498). One explanation for these inconsistencies is that referees adopt a coping strategy of “avoidance”, i.e., when faced with difficult decisions, referees simply avoid making unpopular decisions by waving “play on”

Oligomeric tetrathiafulvalenes in supramolecular chemistry

A range of highly ordered dendritic and oligomeric macromolecules, functionalised with tetrathiafulvalene (TTF) derivatives as a redox-active sub-unit were assembled. In particular, the first dendritic macromolecules incorporating TTF were constructed by the reaction of poly-acid chlorides and alcohol functionalities. Electrochemical techniques showed the novel redox-superstructures to be efficient π-electron donors that are able to undergo two reversible, multi-electron-on oxidations. The TTF-units were established to be acting independently, and the extent to which the redox groups could be oxidised was evaluated. UV studies demonstrated the redox- assemblies to be capable of forming charge-transfer complexes m solution and showed potential for the formation of conducting charge-transfer complexes. Preliminary studies showed the precursors to these compounds to be suitable for use as electrochemical detectors for dopamine. Structural variation of the core units increased the air and thermal stability of the dendritic materials, whilst retaining the characteristics of the multi-redox system. These systems formed stable aggregates of the radical cation and afforded conducting charge- transfer complexes with TCNQ. The new precursors to multi-TTF systems were then used in attempts to impart redox characteristics on [2]pseudorotaxanes and rotaxanes. Preliminary attempts were made to assemble multi-TTF systems using a TTF derivative as a core and at the periphery

Probabilistic Invariance for Gaussian Process State Space Models

Gaussian process state space models are becoming common tools for the analysis and design of nonlinear systems with uncertain dynamics. When designing control policies for these systems, safety is an important property to consider. In this paper, we provide safety guarantees for Gaussian process state space models in the form of probabilistic invariant sets, where the state trajectory is guaranteed to lie within an invariant set for all time with a particular probability. We provide a sufficient condition in the form of a linear matrix inequality to evaluate the probabilistic invariance of the system, and we demonstrate our contributions with an illustrative example

Synthesis of bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) derivatives functionalised with two, four or eight hydroxyl groups

Short synthetic routes to a range of BEDT-TTF derivatives functionalised with two, four or eight hydroxyl groups are reported, of interest because of their potential for introducing hydrogen bonding between donor and anion into their radical cation salts. The cycloaddition of 1,3-dithiole-2,4,5-trithione with alkenes to construct 5,6-dihydro-1,3-dithiolo[4,5-b]1,4-dithiin-2-thiones is a key step, with homo- or hetero-coupling procedures and O-deprotection completing the syntheses. The first synthesis of a single diastereomer of tetrakis(hydroxymethyl)BEDT-TTF, the cis, trans product, was achieved by careful choice of O-protecting groups to facilitate separation of homo- and hetero-coupled products. Cyclisation of the trithione with enantiopure 1R,2R,5R,6R-bis(O,O-isopropylidene)hex-3-ene-1,2,5,6-tetrol (from D-mannitol) gave two separable diastereomeric thiones, which can be transformed to enantiomeric BEDT-TTF derivatives with four or eight hydroxyl groups

Walking on Thin Ice: Exploring Demands and Means of Coping During an Extreme Expedition

The present exploratory study was undertaken with two experienced explorers in order to examine daily events, perceived demands, coping strategies, and mood during a unique 636–675 km ‘‘double solo’’ crossing of Lake Baikal, a frozen lake in Siberia. A 59-year-old female explorer and a 49-year-old male explorer completed a daily survey and written diary during the expedition to collect situational data. Two semi-structured interviews were also completed, one within 24 hours and a second within four months of their return. These interviews sought to identify demands and coping efforts perceived as being most pertinent during their expedition. Guided by the work of Skinner et al. (2003), families of coping were organized around three human concerns (autonomy, relatedness, and competence) and two targets of coping (self or context). Findings illustrate two very different expedition experiences as evidenced by demands faced and coping strategies utilized, which influenced perceptions of workload and emotions experienced. Each explorer brought idiosyncrasies, which, when combined with different expedition experiences, bore influence on coping behaviors (focused on the self or context) and outcomes relative to the concerns of autonomy, relatedness, and competency. In discussing the findings, recommendations are offered for those preparing to undertake expeditions in extreme environments
