Multiple-choice examinations play a critical role in university admissions across the world. A key question is whether imposing penalties for wrong answers on these examinations deters guessing from women more than men, disadvantaging female test-takers. We consider data from a large-scale, high-stakes policy change that removed penalties for wrong answers on the national college entry examination in Chile. The policy change reduced a large gender gap in questions skipped. It also narrowed gender gaps in performance, primarily among high-performing test-takers, and in the fields of math, social science, and chemistry.

The article describes the situation of gender equality in Ukraine and in the world during the last 5 years, identifies the leading countries in moving towards gender equality in various fields of life by analyzing the indicators of the Global Gender Gap Report of the World Economic Forum. These indicators include: Economic Participation and Opportunity, Educational Attainment, Health and Survival, Political Empowerment, which are the part of a single index that determines the position of countries in the overall ranking. Based on the results of this analysis, Ukraine has improved value of gender equality index, although in the overall ranking of countries Ukraine has lost its position and dropped 11 ranks lower than in 2014. This means that, among all the countries surveyed by the World Economic Forum, there are countries that are moving much faster towards gender equality than Ukraine. In addition, the article includes the investigation of the gender representation among the board members of 5 enterprises of Ukraine for 2014-2017, which represent the leading sectors of the Ukrainian economy. The dynamics of changes in the level of performance of these enterprises using the return on assets (ROA) indicator is analyzed, the relationship between the leadership of the enterprises and the value of the ROA indicator is graphically presented. The obtained results do not give a clear answer about the gender impact on the enterprise performance. The reason for this is a number of factors, such as: insufficient statistical sampling of enterprises; the selected performance indicator of enterprise activities does not fully reflect the impact of the gender factor on enterprise activities; the methodology used in the work needs improvements, or it is necessary to choose a totally new approach to the analysis of the investigated issue under study. Gender representation among board members and its impact on enterprise performance should be investigated further. Key words: gender, gender equality, enterprise board members, return on assets.

The future direction of electric vehicle (EV) transportation in relation to the energy demand for charging EVs needs a more sustainable roadmap, compared to the current reliance on the centralised electricity grid system. It is common knowledge that the current state of electricity grids in the biggest economies of the world today suffer a perennial problem of power losses; and were not designed for the uptake and integration of the growing number of large-scale EV charging power demands from the grids. To promote sustainable EV transportation, this study aims to review the current state of research and development around this field. This study is significant to the effect that it accomplishes four major objectives. (1) First, the implication of large-scale EV integration to the electricity grid is assessed by looking at the impact on the distribution network. (2) Secondly, it provides energy management strategies for optimizing plug-in EVs load demand on the electricity distribution network. (3) It provides a clear direction and an overview on sustainable EV charging infrastructure, which is highlighted as one of the key factors that enables the promotion and sustainability of the EV market and transportation sector, re-engineered to support the United Nations Climate Change Agenda. Finally, a conclusion is made with some policy recommendations provided for the promotion of the electric vehicle market and widespread adoption in any economy of the world.

Unbiased science dissemination has the potential to alleviate some of the known gender disparities in academia by exposing female scholars’ work to other scientists and the public. And yet, we lack comprehensive understanding of the relationship between gender and science dissemination online. Our large-scale analyses, encompassing half a million scholars, revealed that female scholars’ work is mentioned less frequently than male scholars’ work in all research areas. When exploring the characteristics associated with online success, we found that the impact of prior work, social capital, and gendered tie formation in coauthorship networks are linked with online success for men, but not for women—even in the areas with the highest female representation. These results suggest that while men’s scientific impact and collaboration networks are associated with higher visibility online, there are no universally identifiable facets associated with success for women. Our comprehensive empirical evidence indicates that the gender gap in online science dissemination is coupled with a lack of understanding the characteristics that are linked with female scholars’ success, which might hinder efforts to close the gender gap in visibility.

Billions of people from around the world believe in vengeful gods who punish immoral behavior. These punitive religious beliefs may foster prosociality and contribute to large-scale cooperation, but little is known about how these beliefs emerge and why people adopt them in the first place. We present a cultural-psychological model suggesting that cultural tightness—the strictness of cultural norms and normative punishment—helps to catalyze punitive religious beliefs by increasing people’s motivation to punish norm violators. Our model also suggests that tightness mediates the impact of ecological threat on punitive belief, explaining why punitive religious beliefs are most common in regions with high levels of ecological threat. Five multi-method studies support these predictions. Studies 1-3 focus on the effect of cultural tightness on punitive religious beliefs. Historical increases in cultural tightness precede and predict historical increases in punitive beliefs (Study 1), and both manipulating people’s support for tightness (Study 2) and placing people in a simulated tight society (Study 3) increase punitive religious beliefs via the personal motivation to punish norm violators. Studies 4-5 focus on whether cultural tightness mediates the link between ecological threat and punitive religious beliefs. Cultural tightness helps explain why U.S. states with high ecological threat (e.g. natural hazards, scarcity) have the highest levels of punitive religious beliefs (Study 4), and why experimental manipulations of threat increase punitive religious beliefs (Study 5). Past research shows how religion impacts culture, but our studies show how culture can shape religion.

Since 2000 the volume of economic reasoned migration has been rapidly rising in Kyrgyzstan. The number of labor migrants currently working abroad counts around 600 thousand people or about 10% of the population of Kyrgyzstan. With growing pattern of labor migration, the amount of remittances has grown as well. According to the World Bank, Kyrgyzstan is on the first place in the world in terms of share of remittances in the GDP (34%) in 2016. The main remittance sending countries for 2005-2016 periods are the Russian federation and Kazakhstan. The large scale of migration outflow and remittances, making domestic economy of Kyrgyzstan dependent on external shocks, related with migration. For this reason, the purpose of this study is to examine the impact the high level of remittances inflow from labor migration on the exchange rates, particularly on the reel effective exchange rate of Kyrgyzstan for the period of 2005-2016. The empirical analysis was carried out with Cointegration model, and according to the results obtained, the remittances and real effective exchange rates have long run relationship.

The novel coronavirus (COVID-19) pandemic is intensifying all over the world, but some countries, including China, have developed extensive and successful experience in controlling this pandemic. In this context, some questions arise naturally: What can countries caught up in the epidemic learn from China’s experience? In regions where the outbreak is under control, what would lead to a resurgence of the epidemic? To address these issues, we investigate China’s experience in anticontagion interventions and reopening process, focusing on the coevolution of epidemic and awareness during COVID-19 outbreak. Through an empirical analysis based on large-scale data and simulation based on a metapopulation and multilayer network model, we ascertain the impact of human movements and awareness diffusion on the epidemic, elucidate the inherent patterns and effective interventions of different epidemic prevention methods, and highlight the crunch time of each measure. The results are also employed to analyze COVID-19 evolution in other countries so as to find unified rules in complex situations around the world and provide advice on anticontagion and reopening policies. Our findings explain some key mechanisms of epidemic prevention and may help the epidemic analysis and decision-making in various countries suffering from COVID-19.

The Covid-19 pandemic was taking place in almost all countries around the world. Along with the increasingly vigorous government strategy in tackling the spread of the corona virus that was still endemic until now, the government had started to enforce the Large-Scale Social Restrictions (PSBB) with the signing of Government Regulation (PP) No. 21 of 2020 about PSBB which was considered able to accelerate countermeasures while preventing the spread of corona that was increasingly widespread in Indonesia. The research method used was normative prescriptive. The government put forward the principle of the state as a problem solver. The government minimized the use of region errors as legitimacy to decentralization. The government should facilitated regional best practices in handling the pandemic. Thus, the pandemic can be handled more effectively. The consideration, the region had special needs which were not always accommodated in national policies. The government policy should be able to encourage the birth of regional innovations in handling the pandemic as a form of fulfilling human rights in the field of health. Innovation was useful in getting around the limitations and differences in the context of each region. In principle, decentralization required positive incentives, not penalties. Therefore, incentive-based central policies were more awaited in handling and minimizing the impact of the pandemic.

The appearance of COVID-19 brought to Brazil, and to the world, innumerable methods to contain the increase of infected people. These methods are necessary to avoid the spread of the virus and include social distancing and quarantine of the population. Knowing that these methods have a big impact on the educational system. This study has as its objective to verify the process of teaching and learning, in educational spaces and environments, in times of a pandemic. In order to look for a pattern in established actions in educational programs to incorporate in large scale the tools of educational technology at a distance (distance learning), for example platforms and virtual teaching environments designed to guarantee the pedagogical processes of learning and ameliorate the impact of absence from the classroom during the pandemic, and its post-pandemic consequences. We emphasize the importance of the teacher as mediator, understanding that this professional should respect the different levels of learning of the students and try to carry out activities that help with the improvement of practical education for the appropriate environment and spaces of interaction.

AbstractMetabolic studies and animal knockout models point to the critical role of polyunsaturated docosahexaenoic acid (22:6, DHA)-containing phospholipids (PLs) in physiology. Here, we study the impact of DHA-PLs on the dynamics of transendothelial cell macroapertures (TEMs) tunnels triggered by the RhoA GTPase inhibitory exotoxin C3 from Clostridium botulinum. Through lipidomic analyses, we show that primary human umbilical vein endothelial cells (HUVECs) subjected to DHA-diet undergo a 6-fold DHA-PLs enrichment in plasma membrane at the expense of monounsaturated OA-PLs. In contrast, OA-diet had almost no effect on PLs composition. Consequently, DHA treatment increases the nucleation rate of TEMs by 2-fold that we ascribe to a reduction of cell thickness. We reveal that the global transcellular area of cells remains conserved through a reduction of the width and lifetime of TEMs. Altogether, we reveal a homeostasis between plasma membrane DHA-PLs content and large-scale membrane dynamics.

Abstract One of the biggest threats to humanity are pandemics. In our global society they can rage around the world with an immense toll in terms of human, economic and social impact. Forecasting the spreading of a pandemic is, therefore, paramount in helping governments to enforce a number of social and economic measures, apt at curbing the pandemic and dealing with its aftermath. We demonstrate that the epidemic renormalisation group approach to pandemics provides an effective and simple way to investigate the dynamics of disease transmission and spreading across different regions of the world. The framework also allows for reliable projections on the impact of travel limitations and social distancing measures on global epidemic spread. We test and calibrate it on reported COVID-19 cases while unveiling the mechanism that governs the delay in the relative peaks of newly infected cases among different regions of the globe. We discover that social distancing measures are more effective than travel limitations across borders in delaying the epidemic peak. We further provide the link to compartmental models such as the time-honoured SIR-like models. We also show how to generalise the framework to account for the interactions across several regions of the world, replacing or complementing large scale simulations.
