Understanding parental psychopathology interaction is important in preventing negative family outcomes. This study investigated the effect of paternal psychiatric history on maternal depressive symptom trajectory from birth to 12 months postpartum. Maternal Edinburgh Postpartum Depression screens were collected at 1, 6 and 12 months and fathers' psychiatric diagnoses were assessed with the Structured Clinical Interview for DSM-IV from 64 families. There was not a significant difference in the trajectory of maternal depressive symptoms between mothers with partners with history of or a current psychiatric condition or those without a condition. However, mothers with partners with substance abuse history had higher levels of depressive symptoms relative to those affected by mood/anxiety disorders or those without a disorder. Our results call for a closer look at paternal history of substance abuse when treating postpartum maternal depression.

Guided by feminist perspectives, we critique existing approaches to the study of womenʼs entrepreneurship on epistemological grounds and suggest that the entrepreneurship field needs to recognize gendered assumptions in theorizing. Deploying a feminist framework, we suggest that understanding the “gender gap” in entrepreneurship requires focus on institutional and structural barriers women entrepreneurs face. Existing studies of women entrepreneurs often compare women with men without considering how gender and gender relations impact the very concepts and ideas of entrepreneurship. We propose, therefore, a conceptualization of entrepreneurship that illuminates gender bias and calls attention to the interrelated individual, institutional, and structural barriers in the entrepreneurial process that arrive out of societal and cultural gender norms. Through praxis or engaged practice, we redirect scholarship in the entrepreneurship field, while proposing ways that can promote gender equality in entrepreneurial activities. In all, our gender integrative conceptualization of entrepreneurship contributes to the entrepreneurship field by recognizing and addressing a more expansive realm of influential factors within the entrepreneurial ecosystem that have previously been researched separately.

Since Zuckerberg's announcement to change Facebook's name to Meta Platforms Inc. on October 28, 2021, the concept of the metaverse has gained unprecedented popularity in the business world. Tech giants, SMEs and start-ups across various sectors are making substantial investments in metaverse-related technologies. Despite this, scholarly research in entrepreneurship and strategic management regarding the metaverse remains limited. This paper, grounded in value creation theory, aims to analyze how value is generated in the metaverse era.

This paper conducts a thematic analysis of 895 press releases published by LexisNexis between October 28, 2021, and October 28, 2022. The analysis identifies the primary emerging themes related to value creation in the metaverse age.

The thematic analysis reveals four significant emerging themes concerning value creation in the metaverse age: (1) factors enabling value creation, (2) digital resources contributing to value creation, (3) motives driving value creation and (4) practices of value creation.

This paper represents the inaugural attempt to analyze the metaverse through a value creation lens. Given the substantial investments and growing academic interest in the metaverse, understanding value creation in this context is a pressing concern. Additionally, this study provides valuable insights and suggests critical questions for future research on the metaverse.

In this study we confirm the often assumed but largely untested belief that entrepreneurs think and behave differently than others. We examine a group of more than 700 nascent entrepreneurs and 400 nonentrepreneurs. We determine the entrepreneurs’ cognitive style propensity for problem solving (Innovator versus Adaptor); we compare their expectations; and, we examine the outcomes (performance and start-up) of their ventures. We find that nascent entrepreneurs are more likely to be overly optimistic Innovators, most people are Adaptors, and oneʼs cognitive style can indeed play a role in the initial development and outcome for the venture, but not always as expected.

This study aims to develop an experimentally validated three-dimensional numerical model for predicting different flow patterns produced with a gas dynamic virtual nozzle (GDVN).

The physical model is posed in the mixture formulation and copes with the unsteady, incompressible, isothermal, Newtonian, low turbulent two-phase flow. The computational fluid dynamics numerical solution is based on the half-space finite volume discretisation. The geo-reconstruct volume-of-fluid scheme tracks the interphase boundary between the gas and the liquid. To ensure numerical stability in the transition regime and adequately account for turbulent behaviour, the k-ω shear stress transport turbulence model is used. The model is validated by comparison with the experimental measurements on a vertical, downward-positioned GDVN configuration. Three different combinations of air and water volumetric flow rates have been solved numerically in the range of Reynolds numbers for airflow 1,009–2,596 and water 61–133, respectively, at Weber numbers 1.2–6.2.

The half-space symmetry allows the numerical reconstruction of the dripping, jetting and indication of the whipping mode. The kinetic energy transfer from the gas to the liquid is analysed, and locations with locally increased gas kinetic energy are observed. The calculated jet shapes reasonably well match the experimentally obtained high-speed camera videos.

The model is used for the virtual studies of new GDVN nozzle designs and optimisation of their operation.

To the best of the authors’ knowledge, the developed model numerically reconstructs all three GDVN flow regimes for the first time.

This chapter presents a broad introduction to women’s varied interactions with drugs and drug markets. It provides a brief overview of the international framework of drug control and the ways in which drug policy enforcement differently impacts women and men. It highlights the negative and disproportionate impacts on women of criminalisation-based approaches and how drug policy serves to reinforce existing problems of structural discrimination. This provides context for the contributions to this edited collection, which are summarised in the introduction. The book situates drug policy reform as a crucial and underlooked feminist issue.
