With natural disasters occurring with more frequency and severity, understanding how to facilitate survivors’ resilience and recovery is becoming increasingly important. The Camp Fire in California, which started on November 8, 2018, was one of the most destructive wildfires in recorded history in terms of loss of life and damage to property. Aid from many types of entities (e.g., non-profits, governments, and for-profits) at various levels (e.g., local, state, and federal) was available to survivors, but perhaps the most influential source of support was Disaster Facebook Groups. In the month after the Camp Fire, around 50 Camp Fire Facebook Groups (CFFGs) were created, with over 100 CFFGs existing over the course of recovery. CFFGs are Facebook Groups with the goal of helping Camp Fire survivors. The support exchanged in CFFGs was immense and ranged from financial assistance to emotional support to community building. <br><br>This dissertation offers a mixed-method, event-specific case study of the use and utility of Disaster Facebook Groups after the Camp Fire. I examined how CFFGs offered unique and valuable spaces for connection that allowed members to engage in resilience organizing and disaster response and recovery. To conduct this case study, after engaging in observations of the Groups for over two years, I interviewed 25 administrators of CFFGs and distributed a survey in the Groups that was completed by survivors of the Camp Fire who were members of at least one CFFG during their recovery. I used network perspectives and the Communication Theory of Resilience (Buzzanell, 2010, 2019) as lenses through which administrators’ and survivors’ experiences with CFFGs was understood. I also analyzed the two datasets using multiple and mixed methods but primarily thematic analysis and path modeling. <br><br>The analyses for this case study are presented in four studies. The first two studies provide an understanding of the spaces for connection offered by CFFGs (i.e., characterizing the CFFGs and describing the spaces for connection as both helpful and hurtful), while the last two studies examine the use and utility of CFFGs (i.e., explaining the evolution of activity in CFFGs and investigating the connectivity and social support in CFFGs). <br><br>Across the four studies, I explored three central arguments, which are the primary contributions of this dissertation. First, I advocated for incorporating network thinking into resilience theorizing. With the findings of this dissertation, I extend the Communication Theory of Resilience by offering “managing communication networks” as a refinement of its fourth process of resilience (i.e., using and maintaining communication networks). Managing communication networks addresses the active strategies people use to manage their communication networks, including expanding, contracting, maintaining, and using their communication networks, as they endure and overcome hardship. I also forward the argument that people’s resilience is encompassed by their social networks, meaning their social network can be passively implicated by their resilience or actively involved in their resilience, but can also initiate resilience on their behalf.<br><br>Second, I contended Disaster Facebook Groups offer unique and valuable spaces for connection that facilitate resilience organizing and disaster response for at least five reasons. I argued that Disaster Facebook Groups empower emergent organizing; privilege local knowledge; are convenient; lack anonymity which adds authenticity; and allow for individualization. The findings of this dissertation provide evidence of how these reasons converged in CFFGs to enable members to exchange support that was not, and could not be, available elsewhere.<br><br>Third, I hypothesized that the use of Disaster Facebook Groups would predict the utility of Disaster Facebook Groups, resilience, and recovery for survivors. I tested two models that use different variables to represent the use and utility of CFFGs and recovery from the Camp Fire. The first model investigated how activity in CFFGs influenced the perceived helpfulness of CFFGs and how both the activity in and perceived helpfulness of CFFGs influenced the extent of recovery for survivors. I used retrospective data about five time points across survivors’ first two years of recovery and found the model was most explanative up to one month after the Fire. The second model assessed how various indicators of connectivity in CFFGs impacted received social support (i.e., informational, emotional, and tangible support), resilience, and satisfaction with recovery for survivors. The intensity of survivors’ connections to CFFGs, when they joined their first CFFG, and how many Facebook Friends they gained from their participation in CFFGs were the most predictive indicators of connectivity. From the Groups, survivors reported receiving informational support more than emotional support and emotional support more than tangible support.<br><br>I put the findings of the four studies, as well as the three central arguments, in conversation with each other in the discussion section, focusing on theory, practice, and methodology. Regarding theory, I contribute network thinking to resilience theorizing: I underscore resilience as an inherently networked process; I acknowledge expanding and contracting communication networks as sub-processes of resilience that complement but are distinctly different from using and maintaining communication networks; and I forward “managing communication networks” as a refinement and extension of the Communication Theory of Resilience’s fourth process of resilience (i.e., using and maintaining communication networks). Related to practice, I call for the continuation of conversations around Disaster Facebook Groups as unique and valuable spaces for connection, particularly regarding the five reasons I established. I also give suggestions for practice related to the use and utility of Disaster Facebook Groups for disaster response and recovery. For methodological considerations, I discuss the importance of forming relationships with participants when engaging in research about online communities and natural disasters and call to question the translation of findings about social media across platforms and the role of neoliberalism in resilience and disaster research and practice. Despite its limitations, this dissertation makes meaningful contributions to theory, practice, and methodology, while offering fruitful directions for future research. This mixed-method, event-specific case study brings attention to the influential citizen-driven disaster response in Facebook Groups after the Camp Fire. <br>

Background Open source is largely accepted as an important innovation driver in the technology industry. Even though inclusion and diversity is beneficial for the success of technology projects (including open source software projects), many statistics are pointing out that diversity in open source is even worse than in the technology sector in general. The unequal representation of minorities (in this limited scope study represented by women) has negative effects on the innovation potential of many tech-related companies and is a major cause of corporate companies’ concerns. To attract more women and increase their retention in open source software projects and communities, the understanding of reasons behind the decisions on why they leave/defect an open source project can be is essential for the development of the effective retention strategies in OSS.  Objective Based on the extensive literature review conducted by Trinkenreich, et al. (2021), only a few studies make a theoretical connection to why women leave (or avoid) open source software projects. This study aimed to explore the challenges faced by women in open source that may predict (or influence) their intention to leave/defect an open source software project/community. Thus, the following research question was formulated: What are the specific challenges faced by women in OS that may predict (or influence) their intention to leave an OSS project/community? Methodology The initial in-depth literature review discovered a list of socio-cultural challenges faced by women when contributing to open source projects. Trinkenreich, et al. (2021) have grouped these challenges conceptually as follows: (1) Lack of peer parity; (2) Non-inclusive communication; (3) Toxic culture; (4)  Impostor syndrome; (5) Community reception issues; (6) Stereotyping; (7) Work-life balance issues, (8) Gender-identified contributions. Additionally, one of the authors of this study found an existing dataset on the state of diversity, equity, and inclusion in open source as of 2021. The survey ‘2021 Diversity, Equity, and Inclusion in Open Source’ was developed and distributed by the Linux Foundation. The data for this survey was gathered in 2021 from 2,350 individuals, particularly, from the Foundation’s subscribers and community members, on questions about their sense of inclusion and belongingness in OS communities. The authors of this study made the initial mapping of the questions from the Linux Foundation survey against challenge-clustering developed by Trinkenreich, et al. (2021). This helped to isolate the following groups of challenges for this study: (1) Non-Inclusive Communication &amp; Community Reception Issues; (2) Toxic Culture; and (3) Gender-Identified Contributions &amp; Stereotyping, that are likely to contribute to women leaving/defecting an OSS project/community. Altogether, this helped to formulate two hypotheses: null  (H0) and alternative  (HA) which highlight the relationships between different variables in the dataset. The hypotheses were tested using multiple regression analysis. To test the hypotheses and answer the research question, the authors of this study did not design the survey questions themselves but rather observed them directly through the questions of the Linux Foundation survey. In the context of this study (viz., a small-scale applied research project) capitalizing on the secondary data made sense as explained further in the study. A multiple regression was carried out to explore whether any of the challenges (e.g., lack of response to or rejection of contributions or questions; experience of conflict or interpersonal tension between you and another contributor; experience of written or spoken language that made a women feel unwelcome; experience of threats of violence, stalking; experience of unsolicited sexual advances or comments; experience of stereotyping based on perceived demographic characteristics; experience of impersonation or malicious publication of personal information; experience of background-based harassment) could significantly predict (or influence) women’s intention to leave/defect an open source software project/community. Results The results of multiple regression analysis reject the null hypothesis. The following predictors (i.e., independent variables): Q17_04_violence_stalking_experience, Q17_06_stereotyping_experience, and Q18_background_based_harassment are statistically significant and thus contribute to the regression models because their statistical significance (i.e., the p-value) is less than 0.05. Based on the findings of the study, the challenges that may predict (or influence) women’s intention to leave/defect an open source software project/community can be formulated as follows: o   For the sample ‘North America (Unites States, Canada, Mexico)’   §  [Model 1] experience of threats of violence, stalking directed at women in the context of an open source project  §  [Model 2] experience of threats of violence, stalking and of harassment connected to their background directed at women in the context of an open source project    o   For the sample ‘Europe’   §  [Model 1] experience of stereotyping based on perceived demographic characteristics directed at women in the context of an open source project  §  [Model 2] experience of stereotyping based on perceived demographic characteristics and threats of violence, stalking directed at women in the context of an open source project  Conclusions Women’s intention to leave/defect an OSS project/community can be explained by the following prediction models (i.e., regression equations): o   For the sample ‘North America (Unites States, Canada, Mexico)’   §  [Model 1]  Y = 0.892 – (0.413 * Q17_04_violence_stalking_experience) §  [Model 2]  Y = 0.991 – (0.328 * Q17_04_violence_stalking_experience) – (0.228 * Q18_background_based_harassment)   o   For the sample ‘Europe’   §  [Model 1]  Y = 0.938 – (0.345 * Q17_06_stereotyping_experience) §  [Model 2]  Y = 0.953 – (0.285 * Q17_06_stereotyping_experience) – (0.242 * Q17_04_violence_stalking_experience)   The results of the study also indicate that the models were a significant predictor of women’s intention to leave/defect an OSS project/community: o   For the sample ‘North America (Unites States, Canada, Mexico)’   §  [Model 1]  F(1,134) = 31.671, p = &lt;0.001 §  [Model 2]  F(2,133) = 20.342, p = &lt;0.001   o   For the sample ‘Europe’   §  [Model 1]  F(1,104) = 19.874, p = &lt;0.001 §  [Model 2]  F(2,103) = 13.118, p = &lt;0.001 Contribution to theory and practice Academic value: The findings of this study extend the knowledge about specific challenges faced by women in OS that may predict (or influence) their intention to leave an OSS project/community. Insights for adopting ‘Innovation by All’ workplace culture: The findings of this study provide OSS projects/communities with insights into the hindrances and determinants associated with women’s participation in OS. These insights, in their turn, can be valuable to understand and be aware of when an OSS team/community aims to adopt an ‘Innovation by All’ workplace culture and by doing so  - attain greater team productivity, more innovative and more revolutionary ideas, greater agility, and higher rates of ideas’ implementation, decision-making, and innovation. Internal analysis: The results of this study can be used to inform OSS teams/communities about the most critical aspects they need to address in order to attract more and retain existing female talent. Thus, the findings of this study can serve as an internal analysis for an OSS team/ community to take further actions on including and diversifying their project teams and ensuring that all members stay and keep on contributing to OSS projects. Recommendations for future research The following research proposals are suggested: (1) An extensive quantitative study amongst female contributors of various OSS projects/communities and a comparative analysis of these communities based on different parameters. (2) A replication of this study that examines/explores the specific challenges faced by the representatives of other minority groups in OS that may predict (or influence) their intention to leave an OSS project/community. (3) A comparative study (e.g., women versus men; women versus binary/no-gender participants; and so on) about challenges faced by them in OS that may predict (or influence) the intention to leave an OSS project/community.

Insider trading has long been a controversial phenomenon in the financial world. Several studies have been conducted in the area where the studies have shown ambiguous results. In 2016, Finansipektionen amended the Insider Trading Act, namely that insiders need to report an insider transction within three days. Insiders ability to generate abnormal returns is considered to be in conflict with market efficiency.  This study examines insiders ability to generate abnormal returns on the First North Growth Market during the year 2020, where the sample consists of 47 observations. An eventstudy has been used to investigate the market reaction from the publication of insider trading. Multiple regression analysis has been applied to examine whether there is any difference in the abnormal return based on the position of the insider, the transactionsize of the insider tradingsize and the gender. The hypothesis tests have been answered with the help of a one-sided t-test and multiple regression analysis. A quantitative method and deductive approach have been used in the study where the researcher derived hypotheses based on previous research as well as theories such as the effective markethypothesis, the random-walk theory, the signalinghypothesis, behaviorbased financing and herdbehavior. This study shows that insiders generate abnormal returns during a short-term event window, but that there is no significant difference in the abnormal returns based on the insider’s position, transactionsize and gender. / Insynshandel har länge varit ett omdiskuterat fenomen inom finansvärlden. Flera studier har avlagts inom området som visat på tvetydiga resultat. År 2016 ändrade Finansinspektionen lagen om insynshandel, nämligen att insynspersoner behöver rapportera en insynstransaktion inom tre dagar. Insynspersoners möjlighet till att generera abnormal avkastning anses gå i strid mot marknadseffektiviteten. Denna studie undersöker insynspersoners möjlighet till att generera abnormal avkastning på First North Growth Market under året 2020 där urvalet består av 47 observationer. En eventstudie har använts för att undersöka marknadsreaktionen vid publiceringen av insynshandel. Multipel regressionsanalys har tillämpats för att undersöka ifall det finns någon skillnad i den abnormala avkastningen baserad på befattningen på insynspersonen, transaktionsstorleken av insynshandeln och kön. Hypotesprövningarna har besvarats med hjälp av ett ensidigt t-test samt multipel regressionsanalys. En kvantitativ metod och deduktiv ansats har använts i studien där forskaren härlett hypoteser utifrån tidigare forskning samt teorier som den effektiva marknadshypotesen, random-walk teorin, signaleringshypotesen, beteendebaserad finansiering och flockbeteende. Denna studie visar att insynspersoner genererar abnormal avkastning under ett kortsiktigt eventfönster men att det inte existerar någon signifikant skillnad på den abnormala avkastningen baserat på befattningen av insynspersonen, transaktionsstorleken och kön.

This quantitative methods study explored the knowledge, attitudes and practices of PK-5 teachers on the use of technology applications in the classroom. The Texas State Board of Education has set in place standards for technology applications that require the use of technology applications across all grades. Likewise, the American Academy of Pediatrics (AAP) published new guidelines on the use of technology by children. However, it is the responsibility of teachers to implement and embed these standards, while also paying attention to the recommendations of the AAP. I developed a survey that provided demographic information, and included 12 items to measure the knowledge, attitudes and practices of teachers of technology applications in the classroom. Participants included 251 PK-5 teachers from three different districts in a South Texas region. Multiple regressions were conducted for each of the constructs produced by a factor analysis. Knowledge and attitudes presented no statistically significant results from individual teacher characteristics, but there were statistically significant differences on attitudes by districts. The regression analysis for practice reported a statistically significant difference between teachers that held a master's degree and those who did not. I conclude that technology applications implementation in the PK-5 classrooms is still developing and evolving, but there is still no consistency across districts, and further research in this matter is still needed.

Sport and dance injuries have increased despite improvements in coaching techniques and medical care. Other factors, including psychological ones, were therefore thought to play a role in injury vulnerability. Most of the attempts to explain how psychological variables can affect an athlete's predisposition to injury have been based on anxiety or stress concepts. In this survey type study an interactive approach to stress has been adopted with the goal of finding a relationship between stress and injury in a group of professional ballet dancers. No simple direct relationship was found. Multiple regression analysis was performed and a more complicated relationship between stress indicators and injury was found. When an attempt was made to investigate the significant interaction, no significant correlations were found. However, the correlations were found to be large and negative. This could indicate that if the sample size had been larger significant correlations may have been found. / Psychology / M.A. (Psychology)

Problématique: Dans les dernières années plusieurs études ont exposé les défis auxquels font face des infirmières praticiennes spécialisées en première ligne (IPSPL) dans leur pratique quotidienne. Le manque d’autonomie, l’étendue de pratique limitée et le manque de collaboration dans les équipes de soins sont des facteurs qui sont principalement ressortis de ces études. Les IPSPL aux Québec n’y font pas exception. En effet, leur déploiement a aussi été difficile pour certaines. Ces difficultés rencontrées peuvent inciter les IPSPL à quitter leur travail. Connaître les facteurs influençant l’intention de quitter des IPSPL pourrait donc permettre de maintenir ces professionnelles indispensables dans les milieux de soins. But: Identifier les facteurs qui influencent l’intention de quitter des IPSPL travaillant dans le réseau public de santé québécois. Méthode: La présente étude est une analyse secondaire de données collectées à l’aide d’un questionnaire auto-administré d’une durée approximative de 45 minutes entre mars et avril 2017. L’échantillon de cette étude est composé des 222 IPSPL qui y ont participé. Les facteurs influençant l’intention de quitter mesurés sont : la reconnaissance au travail, les conditions de l’environnement de travail, la relation et le soutien du gestionnaire, le soutien de l’organisation et les pratiques organisationnelles, la relation avec les collègues de travail, les caractéristiques personnelles de l’infirmière et les facteurs externes. Des analyses descriptives, bivariées et une analyse de régression multiple ont été utilisées afin de répondre au but de l’étude. Résultats: 23% des IPSPL pensent quitter leur établissement de soins d’ici les trois prochaines années (n=199), 2% pensent quitter la profession (n=198) et 10% pensent quitter le réseau public au profit d’une organisation privée (n=196). Ces résultats étant comparables à ceux obtenus dans une étude publiée en 2011 où 27,2% des infirmières praticiennes spécialisées (IPS) pensaient quitter leur emploi et où 5,5% d’entre-elles pensaient quitter la profession infirmière (n= 254). Les facteurs associés à l’intention de quitter des IPSPL sont : la diminution du salaire comparativement au salaire net avant d’être IPS et l’absence de flexibilité dans les horaires comparativement à la présence de flexibilité dans les horaires. Aussi, la diminution de la collaboration avec les autres professionnels de la santé et les médecins a été associée avec l’augmentation de l’intention de quitter. Conclusion: Ces nouvelles connaissances pourront aider les gestionnaires dans l’élaboration de stratégies de rétention afin de maintenir les IPSPL en poste. / Problematic: In recent years, several studies have outlined the obstacles faced by nurse practitioners (NP) in primary care in their daily practice. The lack of autonomy, the limited scope of practice and the lack of collaboration in care teams are factors that are highlighted in the studies as challenges faced by these nurses. Nurse practitioners in primary care in Quebec are no exception and their deployment has also been difficult for some. These obstacles can give to the NP the intention to leave their work and knowing the factors influencing this intention could therefore help to maintain these indispensable professionals in the health care system. Aim: Identify the factors that influence the intention to leave of NP in primary care working in the Quebec public health care system. Methods: This study is a secondary analysis of data collected between March and April 2017 using a self-administered questionnaire that lasts approximately 45 minutes. The sample for this study is composed of the 222 NP in primary care who participated. The factors influencing the intention to leave measured are: work rewards, condition of work environment, relationship and support from manager, organizational support and practices, relationships with co-workers, nurse characteristics and external factors. Descriptive, bivariate and multiple regression analyzes were used to meet the aim of the study. Findings: 23% of NP in primary care plan to leave their current establishment within the next three years (n=199), 2% thinks about leaving their profession (n=198) and 10% are thinking about leaving the public health care system in favor of a private organization (n=196). These results are comparable to those obtained by a study published in 2011 where 27.2% of nurse practitioners were thinking about leaving their jobs and 5.5% of them were thinking about leaving the nursing profession (n=254). The factors associated with the intent to leave of the NP in primary care are: the decrease of their salary compared to the net salary before being NP and the lack of flexibility in the work schedules compared to the possibility of having flexibles schedules. Also, the decrease of collaboration with others health professionals and doctors is associated with an increase in the intention to leave. Conclusion: These new informations could assist managers in the development of retention strategies to maintain primary care NP in workplace.

言語変化の原因については、比較言語学や言語地理学双方の立場から、様々な議論がなされてきたが、この問題に対し、変化の原因と変化の結果という関係を多変量的に捉えて知見を得る方法は、十分な議論があるとはいえない。そこで本研究では、これまでの言語変化の議論を踏まえつつ、具体的な事例について、系統推定や重回帰分析、対応分析といった数理的な手法を用いて多変量的な分析を行い、言語変化の原因や原因別の変化の特徴を明らかにした。 / 博士(文化情報学) / Doctor of Culture and Information Science / 同志社大学 / Doshisha University

Extensive research has documented the relationship between listening to certain genres of music and negative effects on social behavior such as aggressive and antisocial behavior. The present study explored whether there are genres of music associated with altruism. Altruistic behavior is defined as behavior that is consistently more caring, helpful, considerate of other's feelings, and self- sacrificing. These behaviors promote our ability to thrive as a community. Yet, few studies have addressed the relationship between music and altruism. Data was collected from 608 college students who completed a self-report altruism scale, music preference measure, the Marlowe Crowne social desirability scale, and a demographic information form in order to see if there is a relationship between choice of music and altruism. A multiple hierarchal regression analysis found music genre choice accounted for 15.9 percent of variance in self-reported altruism. Significant, positive correlations emerged also between altruism and several music genres including alternative, country, classical, and emo.
