Superstitious thoughts or behaviours have been demonstrated to occur frequently and persistently among students and athletes. One major limitation in the superstition in sports literature is that researchers attempt to measure only negative superstitious beliefs; however, to date, little is known about types of superstitions, how superstitions are developed and maintained, their psychological functions and malfunctions, or their behavioural consequences. Study 1 demonstrates the widespread prevalence of superstitions within the present population of undergraduate student athletes in British and Ghanaian universities, and explores several specific superstitions that appear to be particularly common. There were significant main effects of gender and nationality on both positive and negative superstitious beliefs. British student athletes tended to endorse both types of superstition to a greater extent than Ghanaian student athletes, whereas Ghanaian student athletes engaged in superstitious behaviour more than British student athletes. In Study 2, the results suggested that people may enact their positive superstitious beliefs and religion as coping mechanisms and as secondary control strategies to offer them the comfort of feeling in control under conditions of impending failure. Results from the two qualitative studies (Studies 3 and 4) demonstrated some support for elite footballers’ engaging in rituals which serve a functional outcome. These findings suggest that superstitious and religious behaviour can protect against debilitating interpretations of anxiety by increasing self-confidence or allowing athletes to perceive symptoms as controllable and facilitative. Interestingly, athletes who have acquired their superstition by means of conformity note that they experienced cognitive dissonance. Dissonance emerges when two beliefs are inconsistent. Apparent contraction between an athlete’s personal superstitious behaviour and their teams’ superstitious behaviour may give rise to self-doubt, which can erode the athlete’s confidence and create other negative psychological consequences to team process. Study 5 provided empirical evidence for the notion that activation of personal superstition improved performance more than conforming to other superstitions, and that performance was better than that of athletes in the control group. In this regard, the reported findings uniquely contribute to our understanding of superstitions and their effects on psychological as well as behavioural consequences. The present findings are in line with previous research on the psychological functional benefits of superstition. At the same time, these findings suggest fresh interrogations for future research on the subject of superstitions. Possible applications to the student athletes and professional athletes are discussed.

It is in military engagements the task of the air defense to protect valuable assets such as air bases from being destroyed by hostile aircrafts and missiles. In order to fulfill this mission, the defenders are equipped with sensors and firing units. To infer whether a target is hostile and threatening or not is far from a trivial task. This is dealt with in a threat evaluation process, in which the targets are ranked based upon their estimated level of threat posed to the defended assets. Once the degree of threat has been estimated, the problem of weapon allocation comes into the picture. Given that a number of threatening targets have been identified, the defenders need to decide on whether any firing units shall be allocated to the targets, and if so, which firing unit to engage which target. To complicate matters, the outcomes of such engagements are usually stochastic. Moreover, there are often tight time constraints on how fast the threat evaluation and weapon allocation processes need to be executed. There are already today a large number of threat evaluation and weapon allocation (TEWA) systems in use, i.e. decision support systems aiding military decision makers with the threat evaluation and weapon allocation processes. However, despite the critical role of such systems, it is not clear how to evaluate the performance of the systems and their algorithms. Hence, the work in thesis is focused on the development and evaluation of TEWA systems, and the algorithms for threat evaluation and weapon allocation being part of such systems. A number of algorithms for threat evaluation and static weapon allocation are suggested and implemented, and testbeds for facilitating the evaluation of these are developed. Experimental results show that the use of particle swarm optimization is suitable for real-time target-based weapon allocation in situations involving up to approximately ten targets and ten firing units, while it for larger problem sizes gives better results to make use of an enhanced greedy maximum marginal return algorithm, or a genetic algorithm seeded with the solution returned by the greedy algorithm. / Fredrik Johansson forskar också vid Skövde Högskola, Informatics Research Centre / Fredrik Johansson also does research at the University of Skövde, Informatics Research Centre

Hearing impairment is a chronic health condition that affects increasingly younger age groups. Prevalence rates in the working population are estimated to be between four and nine percent when defined by audiometric loss, and between 30 – 40% when using self-report of hearing problems. Hearing impairment can limit and threaten the social functioning of the affected person. It interferes with oral communication, causing activity limitations and participation restrictions. Additionally, a stigma is attached to hearing loss that can lead to feelings of embarrassment, guilt, anxiety and social exclusion. The stigma also poses a threat to the identity of the hearing impaired person who, in return, manages this threat by concealing or disclosing their hearing impairment depending on the social implications. As a consequence, help–seeking is delayed by a considerable amount of time. Although proven to be an effective intervention, amplification is often rejected by working adults. Another available effective intervention is participating in audiologic rehabilitation (AR) programmes. These programmes focus on stigma reduction and communication strategies. Most existing programmes target an elderly population that had been fitted with hearing aids. No programme for working adults who do not wear amplification is published in the literature. The new AR programme “See it! Hear it! Say it!” had been designed for adults who do not wear amplification and previously trialled in the USA. The purpose of this study was to evaluate the short and mid-term outcomes of a version adapted for the New Zealand context, specifically changes in health related quality of life (HRQoL) and cognitive anxiety. Thirteen participants in two groups participated in the study. The design was a quasi–randomised pre-test/post-test/follow-up test with waitlist design. Outcomes were measured with the International Outcome Inventory – Alternative Interventions (IOI-AI), the Hearing Handicap Inventory for Adults (HHIA), the Cognitive Anxiety Scale (CAS) and a non-standardised online questionnaire. Results demonstrated statistically significant differences between pre-group and follow-up assessment outcomes. Effect sizes ranged between 0.606 and 2.114. Participants reported implementing communication strategies in a number of adverse listening environments. These findings provide evidence that the New Zealand specific version of “See it! Hear it! Say it!” is effective in improving HRQoL and reducing cognitive anxiety.

Risky social situations afford the chance to obtain social rewards like acceptance and belonging but also afford the chance of suffering social costs like rejection and social pain. Extant research indicates that social risk triggers approach motivations in higher self-esteem individuals (HSEs) but produces avoidance motivations in lower self-esteem individuals (LSEs; e.g., Stinson et al., 2010). However, no research has investigated the mechanisms that explain this effect: Why does social risk polarize HSEs’ and LSEs’ social motivations? I propose that self-esteem and social risk interact to activate two primal regulatory systems: the challenge-threat evaluation system and the Behavioral Activation-Inhibition Systems. I test this hypothesis by examining whether self-esteem and social risk interact to predict physiological responses consistent with these primal regulatory systems. Participants experienced either a low or high risk social situation, and heart rate reactivity was measured throughout the studies. Across two experiments, for HSEs (i.e., participants scoring one standard deviation above the sample mean), higher social risk increased heart rate reactivity, suggesting activation of challenge appraisals and the behavior activation system. For LSEs (i.e., participants scoring one standard deviation below the sample mean), higher social risk decreased heart rate reactivity, suggesting activation of threat appraisals and the behavior inhibition system. My research provides evidence that the social regulatory function of self-esteem may have developed from more primal regulatory systems, an observation that increases the comprehensiveness of current self-esteem theories. / Graduate / 0451 / 0989 / 0621 / huange@uvic.ca

The current program of research contributes to the World Health Organisation's (WHO, 2004) recent call to pool global resources in the attempt to uncover the most effective countermeasures and polices for the prevention of road trauma. Specifically, this program of research investigates the persuasive outcomes of different emotional health messages in an important applied context, road safety. In this context the use of negative, fear-based approaches has predominated with limited use of more positive-based approaches such as humorous- or pride-based emotional appeals. The overarching aim of the current research program was to examine the effectiveness (i.e., persuasiveness) of positive and negative emotional appeals and, specifically, the issue- or message-relevant affect that such appeals evoke. An additional aim was to ascertain the relative influence and effectiveness of positive and negative emotional appeals for specific target audiences. Particular attention was given to the effectiveness of such messages for males, a high risk road user group of particular concern. The research program also aimed to examine the relative roles and interplay of emotion and cognition in determining message effectiveness. The research focused upon the cognitive constructs of response efficacy (i.e., the extent to which a message incorporates coping strategies and information as well as the extent that individuals' perceive a message as incorporating such coping strategies and information) and involvement (i.e., the extent to which individuals perceive an issue or message as personally relevant and/or as being at risk of experiencing).----- The research program may be conceptualised as three stages, with each stage comprised of an empirical study and one or more manuscripts. The first stage of the research explored the roles and effectiveness of negative and positive emotional appeals. With a substantial body of literature available on the use of fear as a persuasive strategy, Paper One reviewed the theoretical and empirical evidence relating to the function and effectiveness of such appeals. This paper highlighted the mixed findings that have been reported and the controversy surrounding the nature of the fear-persuasion relationship. This paper also highlighted the importance of cognitive components of a message and, in particular, the need to incorporate high levels of response efficacy and to be cognisant of the issue of threat and message relevance.----- Paper Two was based on qualitative research derived from focus groups of licensed drivers (N = 16). The study investigated the roles and effectiveness of positive and negative emotional appeals in road safety advertisements addressing speeding and drink driving. The results suggested that positive and negative emotional appeals may serve different functions. Positive emotional appeals were regarded as a potentially efficacious means of promoting the message of prevention and to model safe behaviour and the rewards received whereas negative emotional appeals were regarded an important way to remind drivers of the dangers of driving.----- The second stage of the research program endeavoured to extend upon the findings reported in the first stage by providing an empirical comparison of positive, humorous appeals and negative, fear-based appeals on a range of outcome measures and over time. In Paper Three, the type of emotional appeal (positive/humorous, negative/fear), level of response efficacy (low, high), level of involvement (low, high), and gender were manipulated in a 2 x 2 x 2 x 2 mixed group design. Licensed drivers (N = 201) completed either a paper-and-pencil or internet-based version of a questionnaire. Prior to the anti-drink driving television advertisements being shown, pre-exposure were assessed. Attitudes and intentions were then assessed immediately after exposure and attitudes, intentions, and behaviour, 2 to 4 weeks later. The results provided evidence of the greater persuasiveness of negative appeals immediately after exposure and greater improvement of positive appeals over time. Also, the results highlighted the importance of high levels of response efficacy, irrespective of emotional appeal type. Paper Three also supported and extended upon earlier findings by examining third-person perceptions in relation to positive, humorous emotional appeals. The results revealed that males reported significantly greater overall influence both to themselves personally, as well as other drivers in general, than females for the humorous appeals. Further, consistent with the multiple roles of affect posited by Elaboration Likelihood Model, explanations were provided for the differential effectiveness of positive and negative affect.----- An additional aim of the second stage of the research program was to clarify an important methodological issue; the sampling adequacy of traditional university student samples versus internet-based samples for health message persuasion research. Fear appeal empirical literature has been criticised for its over-reliance upon student samples. Paper Four examined the extent that the internet may function as an efficacious means of accessing drivers for road safety advertising research. The sample characteristics and results obtained from student and internet samples of drivers were compared empirically. The results provided support for the greater diversity and representativeness of the internet sample and suggested that the two sampling approaches produce equivalent results. This paper served to inform the validity of prior research and informed the choice of sampling methodologies for the subsequent research stage reported in Paper Five.----- The third stage of the research built upon the preceding stages and, most notably, broadened the scope of emotional appeals examined by comparing a range of negative and positive emotional appeals addressing the issue of speeding. Drawing upon the Rossiter-Percy (1987, 1997) motivational model, Paper Five examined two different negative and two positive emotional appeals designed as audio messages. Specifically, the type of emotional appeal (Problem Avoidance/Fear based; Problem Removal/ Agitation or annoyance-based; Social Approval/ Pride-based; and Intellectual Mastery/ Humour-based), level of response efficacy (low, high), level of involvement (low, high), and gender were manipulated in a 2 x 2 x 2 x 2 fully between groups design. A range of persuasion outcome measures, including attitudes and intentions, were assessed immediately after exposure and 1 month later. Further, the study assessed adaptive (message acceptance) as well as maladaptive (message rejection) intentions. The results provided evidence of the effectiveness of humorous-based appeals for males and highlighted that appeals of the same valence (positive or negative) need not have the same persuasive effects. The results also supported the importance of response efficacy for all appeal types and highlighted that a message's overall effectiveness requires consideration of both message acceptance and rejection rates.----- Overall, the current research program, based upon a sound, multi-disciplinary theoretical framework, provided evidence for the need to broaden the scope of emotional appeals in the road safety advertising context and which may also be relevant within a wider health persuasion context. The results of the three studies have important theoretical and practical implications for future campaign development which are discussed.

The current trauma literature lacks adequate differentiation between the effects of sexual versus non-sexual trauma on stimuli responses as well as analyses of the college campus as a uniquely challenging environment for rape survivors. In the first study, 66 adults (22 with sexual trauma experience, 22 with non-sexual trauma experience, and 22 with no significant trauma experience) will be exposed to vignettes with threat-generalized, rape-related or neutral stimuli and their arousal rates in response to these cues will be recorded using Galvanic Skin Response and Heart Rate. It is expected that individuals who have experienced sexual assault will show more arousal in response to the rape-related stimuli than the threat-generalized stimuli. In the second study, 44 college age females who have been sexually assaulted (22 living on a college campus, 22 living off of a college campus) will be exposed to the same vignette conditions as in the first study. These women will also be asked to rate their daily/weekly exposure to certain situations or objects representative of the college environment. It is expected that individuals with a higher exposure to rape culture score will be more aroused by the rape-related stimuli. Mowrer’s two-factor theory of learning (1956) along with the shame (Feldner et al., 2010) accompanying sexual trauma suggests that sexually assaulted individuals will exhibit higher levels of arousal to the rape-related stimuli rather than the threat-generalized stimuli, as other trauma victims might.

South Korea’s security discourse on the nuclear threat posed by North Korea has been dichotomised by its position within the political spectrum between the progressives and conservatives. By drawing upon Securitisation Theory (ST), this study challenges the current security discourse in South Korea, which has divided and misled the public as well as securitising actors. This study examines the security discourses of the Roh Moo-hyun (2003–2008) and Lee Myung-bak (2008–2013) administrations, since they represent the archetypes of the progressives and conservatives respectively. The results of the analysis suggest that the current security discourses that have been prevalent in South Korea do not correspond with reality and, subsequently, the discourses were not able to deal with real challenges that the nuclear threat posed. This research also explains the root cause of the distorted security discourses by applying a ‘discursive chasm’ as a preliminary concept, which indicates a discursive structure that fundamentally impedes the performance of securitising actors’ articulation, and that distorts the discursive formation (securitisation processes). The chasms consist of three elusive discourses: first, a discourse on threats that cannot simply be said to be either imminent or not imminent (nuclear weapons as materiality and discourse); second, a discourse on the other that cannot easily be defined (the difficulty of representation of North Korea); and third, a discourse on measures that cannot easily be realised (intangible extraordinary measures).

[pt] Apresenta-se uma metodologia geral para a avaliação do risco sísmico em sistemas estruturais de engenharia civil com particularizações para edifícios e, a seguir, executam- se aplicações para exemplificar a proposta e para o desenvolvimento de procedimentos complementares aos adotados na prática por métodos determinísticos. Para tal, considera-se a excitação sísmica como um processo aleatório fracamente estacionário, definido por uma função de densidade de espectro de potência da aceleração do movimento do terreno e, no domínio da frequência, determinam-se funções semelhantes para as respostas estruturais. Considera-se, a seguir, o problema de primeira ultrapassagem, de acordo com a solução de Vanmarcke, para determinar a distribuição de probabilidade das respostas estruturais permanecerem abaixo dos níveis numericamente especificados, designados de barreiras. A partir dessas probabilidades, prossegue-se para desenvolver: - uma metodologia para análise de risco sísmico de estruturas prediais, incluindo uma fase preliminar de avaliação da ameaça sísmica para o território nacional; - recursos para avaliação do compromisso probabilístico entre uma função de densidade de espectro de potência da excitação sísmica, para uma região, e um espectro de resposta de projeto proposto para o mesmo local; - o conceito e o procedimento para geração de um espectro de resposta uniformemente provável a ser utilizado para análise do sistema principal e de um espectro de resposta acoplado uniformemente provável para o caso dos sistemas secundários; - uma comparação entre a capacidade a ações horizontais eólicas de estruturas prediais correntes, no Brasil, e o significado dessa resistência para os requisitos de demanda decorrente dos sismos prováveis; - um procedimento para geração de uma função de densidade de espectro de potência objetivo associada a um espectro de resposta de projeto prescrito. A implementação computacional da análise estrutural no domínio da frequência utiliza parcialmente o programa SASSI-2000 e a análise probabilística usa os programas APESS e CA desenvolvidos internamente ao trabalho. / [en] One presents a general methodology to the evaluation of the seismic risk to civil engineering structures, with emphasis to building systems, and in sequence a series of applications is made to exemplify this proposal and to develop complementary procedures to the deterministic structural analysis. On this way, one considers the structural seismic excitation as a weakly stationary random process mainly defined by a ground acceleration power density function and one determines, in the frequency domain, similar structural response quantity functions. One applies, to this response functions, the first passage problem solution according to Vanmarcke and so determining the distribution probability functions of these maximum structural response quantities to remain below specified numerical levels, which are called barriers. From these probability distributions, one proceeds to develop: − a methodology to the structural seismic risk analysis, including a previous phase to define the seismic hazard over the Brazilian territory; − tools to evaluated the probabilistic compromise between a power spectrum density function of the seismic excitation for a region and a design response spectrum proposed to the same area; − the idea of a uniformly probable design response spectrum and the procedures to generate this function to be used in the analyses of the primary system; and to produce a uniformly probable coupled response spectrum for the analyses of secondary systems; − a comparison between the wind horizontal action capacity of regular building structures in Brazil and the capability which would be expected to the seismic hazard; − a procedure to generate a target power spectrum density function for the seismic hazard probabilistically associated to a prescribed design response spectrum for a site. The computational support to the frequency domain structural analysis is taken partially from SASSI-2000 program and the probabilistic paths are made by APESS and CA programs which have been developed inside this work.

La quantité d’informations à laquelle nous sommes chaque jour confrontésconditionne notre survie à la capacité de détecter rapidement ce qui est le pluspertinent dans notre environnement. Nos cerveaux ont ainsi évolué afin dedéclencher, en réponse aux stimuli pertinents, des changements d’état affectif quinous informent alors de l’existence et de la nature de ces stimuli. Or, tandis que lesétats émotionnels, induits par des états corporels, impactent notre perception desstimuli émotionnels, l’influence de ces états corporels sur l’évaluation de lapertinence de stimuli externes est méconnue. Nous avons ici examiné le rôle queces états du corps, transitoires et socialement signifiants, jouent dans l'évaluation dela pertinence des expressions faciales de menace. Lors de nos testscomportementaux, où variaient le degré de pertinence des stimuli et le focusattentionnel, nous avons modulé l'état corporel des participants à l’aide de posturesdominantes ou non dominantes réalisées avant les tâches. Nous avons alorsdémontré que ces postures influencent l'évaluation de la pertinence des expressionsde menace, en accord avec le statut social qu’elles incarnent. De plus, ceci n’a étérévélé que lorsque le traitement de ces stimuli était implicite, soulignant alors lasaillance de ces derniers. Ainsi, nos résultats démontrent que les états corporelsinfluencent non seulement l'évaluation de la pertinence, mais la déterminent, car desstimuli par ailleurs pertinents ne sont plus évalués comme tels selon la postureadoptée. Ces résultats suggèrent que l’état du corps interagit avec nos états affectifspour signaler à l’observateur quels indices sociaux sont pertinents. / Given the quantity of information with which we are constantly confronted, our survival depends on the ability to rapidly detect and attend to what is most relevant. To this end, our brains have evolved to trigger changes in our affective state in response to relevant objects and events, which inform us of their existence and of their nature. While body-induced affective states impact the perception of congruent emotional stimuli, it is still unknown whether body-induced affective states influence the manner in which the relevance of external stimuli is determined and therefore perceived. Here, we examined the role that socially meaningful transient body states play in the evaluation of relevance of facial displays of threat. In a series of behavioral experiments, we modulated participants’ body state, instructing them to hold dominant or non-dominant postures prior to behavioral tests, in which we varied the degree of relevance of the stimuli and the focus of attention. We first demonstrated that these body postures, in accordance with the social status they embody, influenced the evaluation of the relevance of threatening facial displays. Moreover, this impact occurred where facial displays were processed implicitly, highlighting the saliency of these social cues. Overall, our studies demonstrate, that body states, not only influence the evaluation of relevance, but determine it, as otherwise relevant social cues, were no longer evaluated as such. These findings suggest that body states interact with affective states to signal which social cues are relevant to the observer.
