Injection phobia is a prevalent anxiety disorder that puts youth at risk for adverse health outcomes. There is a need to develop accessible, timely, and effective treatments for injection phobia. Combining telehealth and intensive treatment approaches is a promising new direction for the treatment of youth injection phobia as it could address common accessibility barriers and help youth return to healthier functioning more quickly. In addition to testing a telehealth-delivered, intensive treatment for youth injection phobia, this dissertation project includes a critical review of measures of cognitive biases, which have been proposed to contribute to and maintain anxiety disorders. Chapter 1 presents the results of a novel telehealth-delivered, intensive treatment for youth injection phobia. The study used a multiple baseline design to investigate the acceptability, feasibility, and preliminary efficacy of this intervention in 11 youth with injection phobia (Mage=12.5). I hypothesized that the intervention would be rated as feasible and acceptable, and that youth participants would show significant reductions in injection fear and avoidance following treatment. These hypotheses were supported by the study’s results. Chapter 2 is a case series report that describes how the novel telehealth-delivered, intensive treatment for youth injection phobia was tailored to address factors (i.e., attentional difficulties low motivation, and high clinical acuity) that can interfere with the appropriateness and efficacy of telehealth treatment. Clinical implications are then discussed. Chapter 3 provides a comprehensive review of measures commonly utilized to quantify attentional, interpretation, and memory biases in anxious samples. In this review, I highlight how the psychometric and theoretical shortcomings of current measures limit the field’s ability to accurately capture cognitive biases, and in turn, the nuanced relationship between cognitive biases and anxiety symptoms. I also detail specific measurement considerations that can help guide future research focused on anxiety-linked cognitive biases. Overall, this project 1) demonstrates that a combined telehealth-delivered and intensive treatment approach appears to be a viable and effective delivery format for treating youth injection phobia and 2) provides recommendations for how to improve the measurement of cognitive biases so as to enhance our understanding of the etiology of youth anxiety disorders. / 2026-10-02

No / Purpose To raise awareness of the frequency of bias that can affect the quality of radiographer plain film reading performance studies. Methods Studies that assessed radiographer(s) plain film reading performance were located by searching electronic databases and grey literature, hand-searching journals, personal communication and scanning reference lists. Thirty studies were judged eligible from all data sources. Results A one-way analysis of variance (ANOVA) demonstrates no statistically significant difference (P=0.25) in the mean proportion of biases present from diagnostic accuracy (0.37), performance (0.42) and outcome (0.44) study designs. Pearson¿s correlation coefficient showed no statistically significant linear association between the proportion of biases present for the three different study designs and the year that the study was performed. The frequency of biases in film and observer selection and application of the reference standard was quite low. In contrast, many biases were present concerning independence of film reporting and comparison of reports for concordance. Conclusions The findings indicate variation in the presence of bias in radiographer plain film reading performance studies. The careful consideration of bias is an essential component of study quality and hence the validity of the evidence-base used to underpin radiographic reporting policy.

In the workplace, there are times when discrimination is necessary due to extenuating circumstances that revolve around the form or act of discrimination. It could be conveyed to save a life or avoid future conflict. However, it must be clearly stated as a written law that the act is lawful. When unlawful discrimination occurs, it stages an entirely different tone, as it is mainly conducted out of malice, hatred, greed, control, or ignorance. Over the last few decades, discrimination has existed in the workplace, although Federal laws mandate that it does not occur. It does not exist in just one geographical area or is country specific, but covers a wide spectrum, linking countries together from their points of view to creating rifts amongst those who are affected and those who are not, not only from a business perspective, but social humanistic relationships as well. This thesis will use quantitative and qualitative data to support discrimination of sexual harassment, race or color, and gender issues, as well as personal experiences, and how it has and will continue to impact businesses if the acts do not cease, permanently. Leadership, from the Presidents and Heads of Countries, Chief Executive Officers (CEOs), managers, lowest-ranking supervisor, and employees should make it their personal goal to ensure these issues do not continue or arise in their perspective areas of responsibilities. When employees understand that they are valued, will be taken seriously when reporting acts of discrimination, and that some form of action will be taken, performance and productivity will escalate, and morale will increase in the workplace, resulting in higher productivity and subsequently higher profit margins for the company.

The purpose of this research was to develop a questionnaire to be used to identify barriers and facilitators to women faculty in science, technology, engineering, and mathematics (STEM) academics. The phenomenon known as the leaky pipeline, a theoretical model describing why women are underrepresented in STEM disciplines, was examined. Women have long been underrepresented in STEM professions despite an increase in the number of women earning STEM degrees, suggesting women are faced with barriers that prevent them from achieving equal representation with men. The literature has identified several potential barriers, both historical and new, such as biological inequalities, family responsibilities, commitment differences, competitive differences, gender stereotypes and implicit biases, work environments, and job preference. Major facilitators included mentors and specific policy/program implementation. Barriers and facilitators to faculty members at Western Kentucky University will be identified objectively through the use of this questionnaire in a future study.

The modeling of financial risk, whose shortcomings came to the fore during the financial crisis, generally understands risk from the history of prices and returns. However, the state space of risk is not fully revealed from the history of prices and returns. In this dissertation, certain cognitive biases were modeled, and the simulation results were quantitatively characterized to reveal risk not revealed from the history of prices and returns. This contribution adds to the extant literature on the modeling of financial risk by showing how to reveal parts of the state space of risk not revealed from other methods in use today.

In this study I examine foul calls by NBA referees alongside the difference in aggressiveness of twelve NBA basketball teams as they compete for the Championship Title. I aim to identify referee biases that increase the likelihood of the NBA Finals ending in a later game due to league revenue incentives. My data consists of 91 individual NBA Finals games played between the 2001 and 2016 NBA Finals. After controlling for changes in play as well as the difference in aggressiveness, I find that NBA referee’s foul calls are more dependent on a call on the opposing team in situations with a larger series score spread. Additionally, I identify a consistent officiating bias towards the home team. My results imply an effort by the NBA to increase the probability of the series ending in a later game, possibly motivated by increased revenues for the league and all parties involved.

Les encours de crédit à la consommation représentent 7 voire 8 % du PIB d'un État. Le cadre règlementaire dans lequel le crédit à la consommation s'inscrit a été profondément modifié par la directive européenne 2008/48/CE et par la loi n°2010-737 dite « loi Lagarde ».Notre travail vise donc à répondre à la question suivante : quel type de relation existe-t-il entre les prêteurs et les emprunteurs sur le marché du crédit à la consommation ? Ces relations sont-elles spécifiques ? Trois objectifs sont proposés, pour chacun d'eux , nous présentons un éclairage côté emprunteur et un côté prêteur. Le premier, en lien avec les évolutions réglementaires, montre que l'information est au cœur de la relation et que tout changement ou évolution de l'information impacte la relation. Le second objectif, plus stratégique, montre que la prise en considération de biais de comportement (biais de sur-confiance et d'optimisme) ou que la mise en place d'une relation durable entre le prêteur et l'emprunteur impacte les décisions d'octroi de crédit. Le troisième objectif, de nature financière, montre que la relation prêteur emprunteur amène à la détermination de voies d'endettement « optimales » pour un ménage mais, également, à la réduction du risque du prêteur dans le cadre de la théorie du portefeuille. Une méthodologie à la fois qualitative et quantitative est utilisée. Nous constatons que l'équilibre est de type mélangeant et que la relation bancaire n'impacte qu'indirectement ce marché. La prise en compte de comportements biaisés pour les emprunteurs conduit à une composition du portefeuille de crédits moins risquée pour le prêteur. La relation prêteur emprunteur est appréhendée à partir de l'analyse des systèmes de partage de l'information des 27 États de l'Union Européenne. / Consumer credit outstanding stands at 7 or 8 per cent of the GDP. The regulation frame of consumption credit was profoundly modified by the Consumer credit directive 2008/48/CE and the « Lagarde Law » n°2010-737. Consequently, the question we address in this research is: what type of relationship exists between lenders and borrowers in consumer credit market? Are these relations specific? Three objectives are proposed. In any case, we present a lender position and a borrower position. The first one, linked to regulation evolutions, shows that information is the cornerstone of such a relation and any information impacting it. The second objective, more strategic, shows those behavioral biases considerations (overconfidence and optimism bias) or the elaboration of a long run relationship banking between lenders and borrowers impacts on the decisions of granting credit. The third objective, more financial, shows that this relationship defines “optimal” ways of household's indebtedness and also reduces the loan portfolio risk of a lender. A methodology both qualitative and quantitative is used. It is shown that the equilibrium is a pooling equilibrium and that the relationship banking indirectly impacts the consumer credit market. A composition involving a behavior bias yields a less risked loan portfolio for the lenders. The lender borrower relationship is analyzed from the information sharing systems in the 27 EU countries.

The present work describes the model of heuristic judgment of Kahneman & Frederick (2002) and two experiments based upon it. According to the model people answer a question with an answer to an easier question when making a heuristic judgment. This process is called the attribute substitution because a target attribute of a question is substituted by an associated and easier accessible heuristic attribute. The first experiment investigated whether two heuristic attributes can be used simultaneously during making of a judgment. A part of participants gave 1 or 4 reasons for one of the statements in Linda problem (Tversky & Kahneman, 1983). Numbers of reasons were selected so as to produce a feeling of fluency of disfluency. Although the conjunction fallacy occurred, the writing of the reasons didn't have any influence on the assessment of the probability of the related statement. The second experiment investigated whether the priming of the relation between processing fluency and risk can influence the effect of pronounceability of a food additive name on the assessment of its harmfulness. In accord with previous study (Song & Schwarz, 2009) it was shown that food additives with less pronounceable names were considered as more harmful. The priming didn't have any effect. The present studies...

Allt fler beslut tas i samband med skärmar, bland annat på grund av den ständigt växande e-handeln. När människor tar beslut påverkas de av hur valmiljön är utformad samt av heuristikeroch fördomar, vilka är mentala genvägar. Människor influeras av heuristiker och fördomar dådet ofta är svårt för dem att ta beslut som grundas på all information som presenteras. Knuffarär ett sätt att vägleda människor till att göra specifika val utan att sätta begränsningar för derasfrihet och har företrädesvis använts i icke-digitala kontexter, men har nu även introduceratsinom informatik. För att knuffar ska kunna utvecklas och användas digitalt är det dock viktigtmed kunskap om hur människor gör val samt om den påverkan knuffar har. Även tidigareforskning om digitala knuffar efterfrågar studier om hur digitala knuffar kan designas och omderas påverkan på människors val online. Då knuffar är ett relativt nytt begrepp inom informatik, och att fler studier om ämnetefterfrågas, undersöker denna studie hur digitala knuffar kan designas för att vägledamänniskor till hållbara val på nätet. Studien utfördes med en designorienterad forskningsansatsdär digitala knuffar designades utifrån fyra olika heuristiker och fördomar. Knuffarnaapplicerades sedan på en e-handelssida och testades med hjälp av en prototyp. Processen fördesign och utvärdering av de digitala knuffarna itererades fyra eller fem gånger för attexplorativt testa olika sätt att designa knuffarna på relaterat till forskningsfrågan. Studien bidrarmed ett antal förslag för hur digitala knuffar kan designas utifrån heuristiker och fördomar medfokus på vägledning och hållbarhet. / Decisions are increasingly made in connection with screens, amongst other things due to thecontinuous growth of e-commerce. When people make decisions they are influenced by thechoice environment as well as heuristics and biases, which are mental shortcuts. People areinfluenced by heuristics and biases as it is often difficult for them to make decisions based onall of the information presented. Nudges are a way to guide people to make specific choiceswithout limiting their freedom and have primarily been used in non-digital contexts, but havenow also been introduced in informatics. However, in order for nudges to be able to bedeveloped and used digitally it is important to have knowledge about how people make choicesand the effect nudges have. Previous research on digital nudges also asks for studies on howdigital nudges can be designed and their impact on people's choices online.As nudging is a relatively new term in informatics, as well as research regarding the topic isinquired, this study investigate how digital nudges can be designed to guide people tosustainable choices online. The study was conducted with a design research approach wheredigital nudges were designed based on four different heuristics and biases. The nudges wereapplied on an e-commerce website and tested by means of a prototype. The process fordesigning and evaluating the digital nudges was iterated four or five times to in an exploratoryway test different ways to design the nudges in relation to the research question. The studycontribute with a number of suggestions on how digital nudges can be designed based onheuristics and biases, with guidance and sustainability as focal points.
