The weary founder : sleep problems, ADHD-like tendencies, and entrepreneurial intentions

Scholars have persuasively documented the positive influence of ADHD-like tendencies (the impermanent experience of ADHD-like symptoms) on entrepreneurial intentions. Yet, we know little about the causes of ADHD-like tendencies, and thus about factors that could heighten entrepreneurial intentions through such tendencies. Drawing from the biopsychosocial model, sleep physiology literature, and entrepreneurship literature, we propose that the biological experience of sleep problems may heighten the psychological experience of ADHD-like tendencies, which could nudge people toward the socially-embedded intention to venture. Four studies and a mini meta-analysis provide support, extending several literatures and suggesting that sleep problems could contribute to business founding

Rest, zest and my innovative best: sleep and mood as drivers of entrepreneurs’ innovative behavior

This study investigates the antecedents of an entrepreneur’s day-level innovative behavior. Drawing on 2,420 data points from a 10-day experience sampling study with 121 entrepreneurs, we find that sleep quality is a precursor to an entrepreneur’s subsequent innovative behavior, in accordance with the effort-recovery model. Moreover, sleep quality is positively related to high-activation positive moods (e.g., enthusiastic, inspired) and negatively related to high-activation negative moods (e.g., tension, anxiety). Our multilevel structural equation model indicates that high-activation positive moods mediate the relationship between sleep quality and innovative behavior on a given day. These results are relevant for managing entrepreneurial performance

Hepatitis D double reflex testing of all hepatitis B carriers in low-HBV- and high-HBV/HDV-prevalence countries

Hepatitis D virus (HDV) infection occurs as a coinfection with hepatitis B and increases the risk of hepatocellular carcinoma, decompensated cirrhosis, and mortality compared to hepatitis B virus (HBV) monoinfection. Reliable estimates of the prevalence of HDV infection and disease burden are essential to formulate strategies to find coinfected individuals more effectively and efficiently. The global prevalence of HBV infections was estimated to be 262,240,000 in 2021. Only 1,994,000 of the HBV infections were newly diagnosed in 2021, with more than half of the new diagnoses made in China. Our initial estimates indicated a much lower prevalence of HDV antibody (anti-HDV) and HDV RNA positivity than previously reported in published studies. Accurate estimates of HDV prevalence are needed. The most effective method to generate estimates of the prevalence of anti-HDV and HDV RNA positivity and to find undiagnosed individuals at the national level is to implement double reflex testing. This requires anti-HDV testing of all hepatitis B surface antigen-positive individuals and HDV RNA testing of all anti-HDV-positive individuals. This strategy is manageable for healthcare systems since the number of newly diagnosed HBV cases is low. At the global level, a comprehensive HDV screening strategy would require only 1,994,000 HDV antibody tests and less than 89,000 HDV PCR tests. Double reflex testing is the preferred strategy in countries with a low prevalence of HBV and those with a high prevalence of both HBV and HDV. For example, in the European Union and North America only 35,000 and 22,000 cases, respectively, will require anti-HDV testing annually

When Old and New Selves Collide: Identity Conflict and Entrepreneurial Nostalgia among Ex-Entrepreneurs

Abstract: People undergoing career transitions often bring aspects of old roles into their new work contexts, and this interface can create conflict between lingering aspects of one’s work self and the newer aspects of one’s work self. Yet, we know little about how this conflict between old and new selves shapes employee outcomes. In this research, we examine this issue among ex-entrepreneurs—individuals who have transitioned from a business owner to a wage employee. Drawing from role identity theory, we develop a model of the consequences of conflict between a lingering entrepreneur identity and their current work role identity. We propose that ex-entrepreneurs who experience higher levels of identity conflict will be more likely to experience burnout and less likely to engage in boosterism of their employer, and that these relationships are explained by lower levels of perceived professional identity growth (i.e., progressive identity). We further suggest that the negative effect of conflict on progressive identity is exacerbated by nostalgia for one’s entrepreneurial past. In a three-stage field survey of ex-entrepreneurs and their romantic partners, we found support for these hypotheses using both partner-rated outcomes and self-rated outcomes. We discuss implications for the literature on entrepreneurship careers and work identity in organizations

Presumed patriarchy: How a CEO’s masculine appearance affects perceptions of sexual harassment in organizations

Workplace sexual harassment remains an insidious yet pervasive component of organizational life. Building on research that has established that leaders play an important role in condoning or revoking sexual harassment, we theorize that a CEO’s appearance—specifically, the extent to which their face is prototypically masculine—can influence employee assumptions about the patriarchal nature of organizational hierarchy, which, in turn, influences their perceptions of the degree to which sexual harassment will be tolerated. We test these ideas in three complementary studies. Study 1 observes that employees in large organizations headed by a CEO with a more masculine face report more instances of sexual harassment. Study 2 uses an experiment to show that CEO facial masculinity drives followers’ perceptions that sexual harassment is tolerated in an organization by increasing the presumption that the organization is patriarchal. Study 3 affirms these results with a sample of new employees both before and after their first day on the job. Together, these studies provide evidence that a presumption of patriarchy increases the perceived tolerance for sexual harassment, which yields more observations of sexual harassment in the workplace

Owls, Larks, or Investment Sharks? The Role of Circadian Process in Early-stage Investment Decisions

Investors in early-stage companies want to detect and select high-potential opportunities to maximize their long-term returns. However, in uncertain and risky early-stage investment contexts, company information is often opaque, and decision-making timeframes are compressed. Although there is an abundance of prior work on how investors make structured decisions based on their experience and expertise, there is a very limited understanding of how time-based factors can sway investment decisions. The circadian process is the 24-hour sequence that serves as an individual\u27s internal timer influencing not only sleep cycles, but also attention and performance on a wide range of cognitive tasks. Understanding how the circadian process impacts early-stage investment holds implications for optimal investment decisions. We build on social cognitive theory and propose that investor-level factors (i.e., chronotypes) and environmental factors (time of the day) interact to influence the amount of information investors search for, and consequently, their investment decisions. We hypothesize and find that investors are influenced by the time of day they make early-stage investment decisions. Lark investors make better investment decisions in the morning, whereas owl investors make better decisions in the evening. Information search effort mediates this relationship

Entrepreneurship as an auspicious context for mental health research

The intersection of entrepreneurship and mental health has spurred many novel lines of scholarly inquiry. In this editorial, we summarize 23 such studies that have been published in Journal of Business Venturing Insights over the last seven years. In doing so, we emphasize both the differences and similarities among studies in this emerging body of research. Our work illustrates a variety of silos emerging in this growing research domain, as well as potential opportunities for greater theoretical extensions and cumulative knowledge building. We offer several proposals that establish entrepreneurship as a bridging context for mental health inquiries, a context with the potential to unify previously siloed discoveries and shift the knowledge frontier upwards. We conclude with a note for practitioners on the potential virtuous cycle that awaits

Estimating the prevalence of hepatitis delta virus infection among adults in the United States: A meta-analysis

Background and aims: Suboptimal awareness and low rates of hepatitis delta virus (HDV) testing contribute to underdiagnosis and gaps in accurate estimates of U.S. HDV prevalence. We aim to provide an updated assessment of HDV prevalence in the U.S. using a comprehensive literature review and meta-analysis approach.Methods: A comprehensive literature review of articles reporting HBsAg seroprevalence and anti-HDV prevalence was conducted to calculate country-specific rates and pooled prevalence of CHB and HDV using meta-analyses. Country-specific CHB and HDV rate estimates were combined with number of foreign-born (FB) persons in the U.S. in 2022 from U.S. Census Bureau to estimate total numbers of FB with CHB and HDV, respectively. These estimates were further combined with updated estimates of U.S.-born persons with CHB and HDV to yield the total number of persons with CHB and HDV.Results: In 2022, we estimated 1.971 million (M) (95% CI 1.547-2.508) persons with CHB; 1.547 M (95% CI 1.264-1.831) were FB and 0.424 M (95% CI: 0.282-0.678) were U.S.-born. The weighted average HDV prevalence among FB persons in the U.S. was 4.20% (64 938 [95% CI 33055-97 392] persons), among whom 45% emigrated from Asia, 25% from Africa, and 14% from Europe. When combined with updated estimates of U.S.-born persons with HDV, we estimate 75 005 (95% CI: 42187-108 393) persons with HDV in the U.S.Conclusions: Including both FB and U.S.-born persons, we estimated that 1.971 M and 75 005 persons were living with CHB and HDV, respectively, in the U.S. in 202

Strong Magnetocrystalline Anisotropy Arising from Metal–Ligand Covalency in a Metal–Organic Candidate for 2D Magnetic Order

Layered metal-organic frameworks are promising candidates for new two-dimensional (2D) magnets, as the synthetic programmability of these materials can provide a route to diverse structural and electronic properties. However, such framework materials typically lack the heavy elements that engender magnetocrystalline anisotropy in the monolayer ferromagnets reported to date. Alternative sources of magnetic anisotropy are therefore needed in these materials. Here, we report the synthesis of single crystals of the framework material (NMe4)2[Fe2L3] (H2L = 3,6-dichloro-2,5-dihydroxybenzoquinone) and evaluate the angular dependence of its magnetic properties. Oriented-crystal magnetization measurements reveal strong uniaxial anisotropy, where the easy axis is aligned with the crystallographic c axis. While the spin carriers of this structure are isotropic S = 5/2 FeIII metal centers and S = 1/2 organic linkers, the anisotropy energy of the framework material is comparable to that of reported 2D ferromagnets. Density functional theory calculations indicate that the observed magnetocrystalline anisotropy arises from ligand-to-metal charge transfer that enhances the magnetic anisotropy of the otherwise-isotropic Fe centers, suggesting that metal-ligand covalency can be utilized as a general additive for the development of 2D magnets. These results show the possibility for (NMe4)2[Fe2L3] to retain magnetic order down to the 2D monolayer limit. In addition, the combination of large magnetic anisotropy and semiconducting character in (NMe4)2[Fe2L3] highlights its potential as a new 2D magnetic semiconductor
