Mental health in Germany before, during and after the COVID-19 pandemic.

Based on nationally representative panel data (N person-years = 40,020; N persons = 18,704; Panel Labour Market and Social Security; PASS) from 2018 to 2022, we investigate how mental health changed during and after the COVID-19 pandemic. We employ time-distributed fixed effects regressions to show that mental health (Mental Health Component Summary Score of the SF-12) decreased from the first COVID-19 wave in 2020 onward, leading to the most pronounced mental health decreases during the Delta wave, which began in August 2021. In the summer of 2022, mental health had not returned to baseline levels.

Beyond Eyeball Tests: A Methodical Rebuttal to Fillon et al.'s Commentary.

In our original study, "Consumed by Creed" (Adam-Troian & Bélanger, 2024), we established significant and consistent associations between obsessive-compulsive disorder symptom severity and radical intentions across four distinct U.S. population samples-Environmentalists, Republicans, Democrats, and Muslims-partially or fully mediated by obsessive passion.

Determinants of women's empowerment in Nepal.

Introduction: Nepal is characterized by low empowerment of women which may have negative effects on their health status as well as sexual and reproductive rights. We seek to identify key determinants of women empowerment in Nepal using a rich set of socio-demographic and socio-economic characteristics as well as behavioral factors and regional indicators.

Methods: This study utilizes 4,211 women aged between 15 and 49 years from the 2022 Demographic and Health Survey (DHS) for Nepal.

Making more of less: using divestitures to unlock pharmaceutical innovation.

Pharmaceutical managers have been encouraged to look to acquisitions and alliances for innovation. However, the literature warns that the capacity of a company to 'absorb' new knowledge is limited. Here, we introduce corporate divestitures as a tool for freeing up managerial attention.

Exchange rates and multicommodity international trade: insights from spatial price equilibrium modeling with policy instruments via variational inequalities.

In this paper, we construct a multicommodity international trade spatial price equilibrium model of special relevance to agriculture in which exchange rates are included along with policy instruments in the form of tariffs, subsidies as well as quotas. The model allows for multiple trade routes between country origin nodes and country destination nodes and these trade routes can include different modes of transportation and transport through distinct countries. We capture the impacts of exchange rates through the definition of effective path costs and identify the governing multicommodity international trade spatial price equilibrium conditions, which are then formulated as a variational inequality problem in product path flows.

Gender Gap in Urban Job Market During the Pandemic: The Case of Ukraine.

Remarkable resistance of Ukraine has become in the world focus starting from the dawn of February 24th, 2022. While policymakers draft plans to address the consequences of the war, it is crucial to understand the pre-war labor market context, risks of joblessness, inequalities, and sources of resilience. In this paper, we study inequality in job market outcomes in 2020-2021 during another global disaster-the COVID-19 epidemic.

Impact of a sugar-sweetened beverage tax on sugar producers in Ukraine.

Taxes on sugar-sweetened beverages can promote health and raise revenue. Whether these taxes negatively impact domestic sugar producers, an argument often made by opponents, is understudied. We extended a simulation model based on a uniform specific volume-based tax of UAH 4/L in Ukraine.

Differentiable characteristics of Telegram mediums during protests in Belarus 2020.

Online activism has been pivotal for anti-government protests all around the world. A lot of existing research studies how people use social media to mobilize and coordinate protests. However, some platforms offer more than one kind of medium for communication, in particular, Telegram.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning.

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions.

The globalizability of temporal discounting.

Economic inequality is associated with preferences for smaller, immediate gains over larger, delayed ones. Such temporal discounting may feed into rising global inequality, yet it is unclear whether it is a function of choice preferences or norms, or rather the absence of sufficient resources for immediate needs. It is also not clear whether these reflect true differences in choice patterns between income groups.

2D discontinuous piecewise linear map: Emergence of fashion cycles.

We consider a discrete-time version of the continuous-time fashion cycle model introduced in Matsuyama, 1992. Its dynamics are defined by a 2D discontinuous piecewise linear map depending on three parameters. In the parameter space of the map periodicity, regions associated with attracting cycles of different periods are organized in the period adding and period incrementing bifurcation structures.

Evaluation of the impact of the Mother and Infant Health Project in Ukraine.

This paper exploits a unique opportunity to evaluate the impact of the quality change in the labor and delivery services brought about by the Mother and Infant Health Project in Ukraine. Employing program evaluation methods, we find that the administrative units participating in the Project have exhibited greater improvements in both maternal and infant health compared to the control ones. Among the infant health characteristics, the MIHP impact is most pronounced for infant mortality resulting from deviations in perinatal period.
