With a growing interest in sustainability, organizations and researchers have begun to examine pro-environmental behaviors in the workplace (i.e. employee green behaviors). However, general understanding of employee green behaviors is currently limited due to a lack of measurement tools. In this study, a new scale was developed to measure employee green behavior descriptive norms, which are a source of influence on employee green behaviors that develops from observing others’ behaviors. Initial items and expected scale structure for the Employee Green Behavior Descriptive Norms Scale were developed based on the Green Five Taxonomy of employee green behaviors. Items were refined through pilot test data and a retranslation task. Data on the refined scale, the Ethical Leadership Questionnaire, and a Work-Family Culture Scale were used to test scale structure and gather evidence of construct validity. Study results supported the expected scale structure and construct validity of the newly developed scale. A multi-item, validated scale contributes to organizational assessment of employee green behavior descriptive norms and contributes to the scientific literature on employee green behaviors.

<p>Drawing from research on the halo effect and protected values, consumers’ adoption intentions and willingness to pay a premium for renewable energy were explored. A moderated mediation was tested through two-instance repeated-measures linear regressions in a behavioral experiment with an Amazon MTurk sample. Besides, non-parametric tests were also used to test moderations of protected values and consumers’ demographics. In line with the expected halo effect, the effects of the renewability of the energy sources on consumers’ adoption intentions were mediated through consumers’ perceived comfort. These mediation effects were stronger among consumers with high protected values compared to those with low protected values. The non-parametric tests revealed that people with protected values were also found reluctant to pay a premium price for fossil fuels. Future directions to study the relationship between the renewability of energy sources and consumers’ willingness to pay a premium considering consumers’ demographics are also discussed </p>

Lean Startup Teori (LST) har kommit att växa i popularitet inom entreprenörskap världen över. LST är en teori som för startup- företag skall minska kostnader och tid samt för entreprenörer skapa en arbetsprocess som underlättar beslutsfattande. I denna studie har länkar mellan problematik inom beslutsfattande (overconfidence, prospektteori, gloriaeffekten samt escalation of commitment) och LST undersökts genom semistrukturerade intervjuer med entreprenörer i Sverige. Vidare har generella lärdomar från de olika fallen  undersökts för att belysa fördelar och svagheter inom LST. Då pionjärer inom LST hävdat att teorin lämpar sig inom alla  sektorer och branscher har även detta  påstående granskats. Studien fann att LST- processer motverkar de negativa effekterna associerade med overconfidence och  gloriaeffekten men kan inte hantera de  problem som introduceras i samband med prospektteori samt escalation of commitment. Vidare når studien slutsatsen att LST kräver en fit med varje enskilt startup - företag och fungerar bäst inom branscher och industrier som har låga inträdesbarriärer form av kapitalkrav. / Lean Startup theory (LST) has been growing in popularity in entrepreneurship worldwide. LST is a theory for startup companies to reduce costs and time, and for entrepreneurs to create a process that eases decision-making. In this study, links betweenproblems of decision making (overconfidence, prospect theory, the halo effect and escalation of commitment) and LST has been examined through semi-structured interviews with  entrepreneurs in Sweden. Furthermore, general lessons from the cases has been studied to illustrate advantages and  weaknesses of LST. As pioneers of LST argue that the theory is suitable for all  sectors and industries, this claim has also been examined. The study found that LST processes counteract the negative effects associated with overconfidence and the halo effect, but cannot handle the problems that areintroduced in conjunction with the  prospect theory and escalation of  commitment. Furthermore, the study reaches the conclusion that LST requires a fit with each startup company, and functions best in sectors and industries where the entry barrier of capital requirement is low.

本研究以Chen-Chie（Chen and Chie, 2007）所設計的代理人基模型，探討所得分配對彩券銷售額的影響。這篇論文考量了兩種彩券參與函數，一種是採用模糊推論的方法來呈現代理人購買彩券的決定，在此方式下，並未將可能中奬的期望效果納入。另一種則是以預期效用理論為主軸，並且加入主觀認知的中獎機率。除了彩券參與度外，根據Chen and Chie (2007)的設計，還考慮到兩個購買彩券經驗的觀點，分別是自我意識選號及個體間的獨立性。模型中代理人參數並未固定，取而代之的，是讓代理人具有自動產生參數的能力，所有行為的參數是以遺傳演算法取得其適應性。當代理人進行遺傳演算（社會學習）時，代理人對策略的學習會依照區間的設定，進一步作區域性社會學習及全域社會學習。本論文彙集了上述設計，提供了四種彩券市場行為模型，配合不同的所得分配進行模擬，並且利用統計檢定比較其統計量的變化，分析所得分配對彩券銷售額的影響。 / This study addresses the impact of income distribution on lottery sales using an agent-based modeling approach, specifically, the Chen-Chie model (Chen and Chie, 2007). Two kinds of lottery participation function are considered in this thesis. One is more heuristic and does not require agents’ expectations of the odds. In this case, we use the fuzzy inference system to represent agents’ heuristics. The other explicitly takes agents’ expectations of the odds into account, and a formal expected utility maximization approach is taken. In addition to lottery participation, following Chen and Chie (2007), we also consider two additional empirical aspects of lottery plays, namely, conscious selection and state-dependent utilities. The parameters of agents are not fixed; instead, they are autonomous and all behavioral parameters are adaptive via genetic algorithms. While the population genetic algorithms (social learning) are applied, an idea of nearest neighbors learning is used to further distinguish the global social learning from the local social learning. These setups together give us four behavioral models of lottery markets. We then simulate each of these four markets with different income distribution, and then compare their statistic behavior with statistical test to examine the overall effect of income distribution to lottery sales.

Les labels présents sur les emballages (e.g., « bio », « commerce équitable ») peuvent pousser les individus à sous-évaluer le contenu calorique des aliments, créant ainsi un effet de halo santé. Dans cette thèse, nous défendons l’idée qu’un mécanisme de fausse attribution affective pourrait en partie expliquer cet effet de halo santé. Nous présenterons 11 études ayant pour but de tester empiriquement cette hypothèse. Parmi les principaux résultats, nous avons montré qu’il était possible d’observer cet effet même si les individus ne rapportent pas avoir pris en compte le label dans leur évaluation (Etudes 3) et dans un contexte de double tâche entravant un raisonnement délibéré de leur part (Etudes 4 et 5). Nous avons également pu montrer, par le biais d’une tâche de fausse attribution affective, qu’un stimulus neutre, lorsqu’il est précédé d’un label bio (vs. une image contrôle) est ensuite évalué plus positivement (Etudes 6, 7 et 8). Enfin, nous avons observé une congruence systématique entre la valence de l’amorce (i.e., le label) et la valence de l’évaluation subséquente d’un stimulus neutre (i.e., le contenu calorique d’un produit alimentaire ; Etudes 9, 10 et 11). Ce biais cognitif relatif à nos évaluations caloriques apparaît donc comme un phénomène robuste, ne faisant intervenir que peu d’inférences délibérées de la part des individus et étant guidé par la valence du label (qu’il soit positif ou négatif). / Labels on food products can lead to unwarranted inferences: organic and fair-trade products are perceived as containing fewer calories. This effect is described in the literature as the health halo effect. In this thesis, we argue that an affective misattribution mechanism can partially explain this effect. We present 11 studies testing empirically this hypothesis.Among our main results, we show that this effect still occurs even if participants did not mention that they used the label in their evaluation (Study 3) and when they are under cognitive load, hindering a deliberate reasoning (Studies 4 and 5). By using an affective misattribution procedure, we also show that when a neutral stimulus is preceded by an organic label (vs. a control picture), this stimulus is then evaluated more positively (Studies 6, 7, and 8). Finally, we observed a systematic congruency between the valence of the prime (i.e., the label) and the valence of the evaluation of a neutral stimulus (i.e., the caloric content of a food product; Studies 9, 10, and 11). Taken together, these studies suggest that this cognitive bias is a robust phenomenon, involving a few inferences and mainly driven by the valence of the label (whether positive or negative).

The study was based on cognitive biases with the aim of investigating the extent to which the individual's physical appearance affects the hiring process, and whether individuals who are perceived as more attractive are ascribed more positive characteristics. The study was conducted with a quantitative method, where the data collection was done via an online survey with 62 respondents, the majority of whom had previous experience of decision- making in a recruitment context. The respondents were asked to rate perceived attractiveness, characteristics and employability in four different individuals by looking at different facial images. All questions and rating scales on the questionnaire were based on the validated instruments Competence and warmth scale (CWS) and Job Suitability Scale (JSS). The results showed that more attractive people have a higher mean value than less attractive people in CWS and JSS. It was concluded that the individual's appearance has a significant impact in the hiring process, and that there is a tendency to attribute more positive characteristics to people who are considered more attractive compared to those who are judged to be less attractive. / Studien utgick från kognitiva fördomar med syftet att undersöka i vilken grad individens fysiska utseende påverkar anställningsprocessen, samt om individer som uppfattas som mer attraktiva tillskrivs mer positiva egenskaper. Studien genomfördes med en kvantitativ metod, där datainsamlingen skedde via en online-enkät med 62 respondenter, varav majoriteten hade tidigare erfarenhet av beslutsfattande inom rekryteringssammanhang. Respondenterna fick skatta upplevd attraktivitet, egenskaper och anställningsbarhet hos fyra olika individer genom att titta på olika ansiktsbilder. Samtliga frågor och skattningsskalor på enkäten utgick utifrån de validerade instrumenten Competence and warmth scale (CWS) och Job Suitability Scale (JSS). Resultatet visade att mer attraktiva personer har högre medelvärde än mindre attraktiva personer i CWS och JSS. Sammanfattningsvis drogs slutsatsen att individens utseende har en betydande inverkan i anställningsprocessen, samt att det finns en tendens att attribuera mer positiva egenskaper till personer som anses vara mer attraktiva jämfört med de som bedöms som mindre attraktiva.

Design/Methodology - We conducted a 4×2 mixed-design experiment to examine the impact of attribution and optimal direction of information order on earnings forecast and the impression created about the company. Findings - Results show that the favorable report read first, without attribution, positively affects the investor, and that the favorable information read first, with attribution, undermines the positive effect. Conversely, presenting unfavorable information, with attribution, first, minimizes the impact of this information. Our findings confirm self-promoter’s paradox idea. We also tested a sandwich and an interspersed ordering (control) group; these had the worst results. In a mediation analysis, we found that perceived impression about the company mediates the relationship between information and decision-making. In addition, our results show a significant difference in decision-making influenced by users’ characteristics. In a robustness test, we tested credibility of information as an alternative explanation, finding that credibility was not an alternative explanation for investors’ decision found in the experiment. We conclude by offering suggestions for further study of IM. Originality – To our knowledge, this is the first study that analyses the effects of both attribution and ordering strategies at the same time. Literature has addressed both strategies separately but has not discussed their interactive effect. This research addresses this gap.

Title: The men we don’t see, and the women we can’t hear: A qualitative interview study about prostitution and human trafficking in hotel environment. This qualitative interview study aims to put a light on hotel staff’s experiences of how prostitution and human trafficking exist within their workplaces. We examine this on the basis of the Swedish policy ‘Hotellkurage’ as a crime prevention method in the hotel environment in Northern Sweden. The policy is built on the idea of civil courage and aims to include both hotel staff and hotel guests. Thematic analysis was used to collect data and code it to themes describing similarities, differences and patterns in the data. The theoretical framework for this thesis is based on the routine activity theory, the bystander effect, the emotional labor theory, and the halo effect within stereotypes. By interviewing six informants with different work positions we discovered that it seems to be hard for the hotel staff to intervene based on their gut feeling in situations involving violence. We also found that there is an underlying expectation on hotel staff to have knowledge about handling situations of prostitution and/or human trafficking, and cope with their personal emotions through out emotional labor. The role conflict of being service-minded and intervene in situations involving prostitution or human trafficking are severe. The organizational conditions, response from the management and the cooperation with local police seem to be crucial in order to use methods based on civil courage in hotel staff’s working environment. Hotel staff should be more educated and encouraged to act upon their gut feeling in situations involving prostitution and human trafficking. Finally, the study finds that stereotypes of perpetrators in prostitution and human trafficking usually don’t add up to the stereotypical view of a perpetrator due to their often common apperance. Also, the victims of prostitution and human trafficking are viewed in a stereotypical way, which leads to a higher risk of other vulnerable social groups not to be discovered in the hotel environment.

This thesis focuses on the high dynamic range (HDR) imaging problematic. It describes process of capturing and storage of HDR images in brief. Main part of thesis deals with techniques of how to display HDR images on common visual display devices, which are not able to represent them directly. This process is called tone-mapping. It is firstly described in general and than the text focuses on several techniques of tone-mapping, mainly on tone-mapping using bilateral filtering.
