    Abstract This article aims to offer a comprehensive overview of the existing literature on the hackathon phenomenon to offer scholars a common ground for future research and managers and practitioners research-based guidelines on best planning and running a hackathon. A review of the most relevant literature on hackathons was conducted to serve as the research basis for our integrative model and guidelines. This article synthesizes the research on hackathons to offer comprehensible guidelines for practitioners while also providing questions for future hackathon researchers. We differentiate between the different design characteristics of hackathons while noting their advantages and disadvantages, discuss tools and methodologies for successful hackathon setup and execution step-by-step, and provide recommendations to encourage project continuity.

    Abstract The behavioral decision-making and negotiations literature usually advocates a first-mover advantage, explained the anchoring and adjustment heuristic. Thus, buyers, who according to the social norm, tend to move second, strive to make the first offer to take advantage of this effect. On the other hand, negotiation practitioners and experts often advise the opposite, i.e., moving second. These opposite recommendations regarding first offers are termed the

    Abstract Objectives: The objective of this study was to investigate possible differences in COVID-19-related anxiety based on previous theories in social psychology.
    Study design: Cross-sectional online questionnaire delivered via the crowdworking platform.
    Methods: Four-hundred and seven (120 men and 287 women) adults (aged >18 years) from the United Kingdom answered the State-Trait Anxiety Inventory 'in light of the COVID-19 situation', followed by three health and three financial anxiety items.
    Results: Our findings imply that women are more anxious than men, people are more anxious about others than about themselves, their anxiety about relatives is higher than about strangers, and anxiety about health is higher than about financial issues.
    Conclusions: We suggest that these preliminary findings should be further investigated to help policymakers improve both their treatment of pandemic-related anxiety and their messages.

    Abstract Recent accomplishments in genome sequencing techniques have resulted in vast and complex genomic data sets, which have been used to uncover the genetic correlates of not only strictly medical phenomena but also psychological characteristics such as personality traits. In this commentary, we call for the use of genomic data analysis to unlock the valuable field of the genetics of entrepreneurship. Understanding what makes an entrepreneur and what explains their success is paramount given the importance of entrepreneurship to individual, organizational, and societal growth and success. Most of the studies into the genetics of entrepreneurship have investigated familial entrepreneurial inclinations in the form of parent-offspring comparisons or twin studies. However, these do not offer a complete picture of the etiology of entrepreneurship. The use of big data analytics combined with the rapidly growing field of genetic mapping has the potential to offer a more complete picture of the etiology of entrepreneurship by allowing researchers to pinpoint precisely which genes and pathways underlie entrepreneurial behavior and success. We review the risks and opportunities which accompany this endeavor and make the case that, ultimately, prioritizing more research into the genetics of entrepreneurship has the potential to be of value to both science and society.

    Abstract There is a growing scientific interest around entrepreneurship. One central line of research examines how different personality traits and characteristics such as creativity or resilience relate to entrepreneurial intentions and behavior. In the current research, we add to this literature by focusing on trait victimhood, a trait that entrepreneurship research has overlooked and may be relevant to understanding entrepreneurial tendencies. In two studies in Israel among a sample of entrepreneurship students (Study 1) and a sample representing the general public (Study 2), we show that trait victimhood is negatively related to entrepreneurial personality (Study 1) and behavior (Study 2). Moreover, Study 2 suggests that a strong sense of self-efficacy may buffer against trait victimhood's adverse effects on behavioral entrepreneurship.

    Abstract The novel coronavirus disease 2019 (COVID-19) has brought with it crucial policy- and decision-making situations, especially when making judgments between financial and health concerns. One particularly relevant decision-making phenomenon is the prominence effect, where decision-makers base their decisions on the most prominent attribute of the object at hand (e.g., health concerns) rather than weigh all the attributes together. This bias diminishes when the decision-making mode inhibits heuristic processes. In this study, we tested the prominence of health vs. financial concerns across two decision-making modes - choice (prone to heuristics) and matching (mitigates heuristics) - during the peak of the COVID-19 in the UK using Tversky

    Abstract Entrepreneurship catalyzes economic growth; it generates jobs, advances the economy and solves global challenges. Hence, it is crucial to understand the factors contributing to entrepreneurship and entrepreneurs' development. While many studies have investigated intrapersonal factors for entrepreneurial tendencies, the present study focuses on a critical yet often overlooked interpersonal aspect: attachment orientations. Specifically, this article examines the relationship between adult attachment orientations and entrepreneurial tendencies. Three studies across three countries (Israel, the UK, and Singapore) indicated that an anxious attachment orientation in close relationships is negatively associated with enterprising tendencies. In Israel (Study 1) and Singapore (Study 2), avoidant attachment in close relationships was also negatively correlated to such tendencies. Overall, the more people feel secure in close relationships (lower scores on attachment anxiety or avoidance), the higher their enterprising tendencies. Limitations and future research suggestions are discussed.

    Abstract Background: Optimism is associated with health benefits and improved survival among adults older than 65 years. Whether or not optimism beyond age 85 continues to confer survival benefits is poorly documented. We examine the hypothesis that being optimistic at ages 85 and 90 is associated with improved survival.
    Method: The Jerusalem Longitudinal Study (1990-2020) assessed comorbidity, depression, cognition, social and functional status, and 5-year mortality among a representative community sample, born during 1920-1921, at age 85 (n = 1096) and age 90 (n = 533). Overall optimism (Op-Total) was measured using a validated 7-item score from the Scale of Subjective Wellbeing for Older Persons. The 4 questions concerning positive future expectations (Op-Future) and 3 questions concerning positive experiences (Op-Happy) were also analyzed separately. We determined unadjusted mortality hazards ratios and also adjusted for gender, financial difficulty, marital status, educational status, activities of daily living dependence, physical activity, diabetes mellitus, hypertension, ischemic heart disease, cognitive impairment, and depression.
    Results: Between ages 85-90 and 90-95 years, 33.2% (364/1096) and 44.3% (236/533) people died, respectively. All mean optimism scores declined from age 85 to 90, with males significantly more optimistic than females throughout. All measures of optimism (Op-Total, Op-Future, and Op-Happy) at ages 85 and 90 were significantly associated with improved 5-year survival from age 85 to 90 and 90 to 95, respectively, in both unadjusted and adjusted models. Findings remained unchanged after separately excluding depressed subjects, cognitively impaired subjects, and subjects dying within 6 months from baseline.
    Conclusions: These finding support the hypothesis that being optimistic continues to confer a survival benefit irrespective of advancing age.

    Abstract The COVID-19 crisis has caused severe psychological distress. Governments have been trying to fight the outbreak, inter alia, by enacting various restrictions to maintain social distancing. However, compliance with restrictions depends upon different interpersonal variables. The present study focused on the relationship between attachment patterns, fear of COVID-19, and adherence to COVID-19 guidelines. Participants completed the ECR measure to assess their adult attachment style, in addition to a COVID-19 fear and guidelines compliance questionnaire. We suggest that anxious attachment patterns may be related to heightened fear of COVID-19. Although fear and guideline adherence were positively correlated, secure attachment patterns were correlated to higher adherence than insecure attachment patterns.
