Population Pressures and the North–South Divide between the first century and 2100

This article examines the relationship between the populations of the more and less developed societies between the first century and 2100. Such an analysis reveals a changing dependency between the level of development (and GDP) achieved and population numbers between the first century and 1998. In relation to the past the article suggests a dynamic model for dividing the world into more and less developed areas. In relation to the present and the future it bases the population analysis on the developmental division of the world as published by one of the co-authors of this article. The article largely uses population estimates (with those referring to the past taken from Angus Maddison and those referring to the future from the most recent projections by the United Nations). Taking the 2013 UN projection as a model, it discusses three variants for demographic development in the North and South up to 2100. It argues that the more restrictive population growth variants of the UN projection predict a greater relative ‘Third Worldisation’ of the world than does the most dynamic projection.     

Covid-19 Pandemic,Social Mitigation and Taxation: The Open Veins of Inequality in Latin America

The pandemic of Covid-19 has exposed the veins of inequality in Latin America. With a socioeconomic disaster looming, social emergency policies seemed inevitable. Yet while governments argue over the continuity of such policies and whether the fiscal rules in place should be respected, no sustainable response has come out. This essay problematises whether the pandemic could represent a critical juncture to forge ahead with political narratives that highlight tax exemptions and privileges enjoyed by the rich. We analyse the mitigation measures adopted by Argentina, Brazil, Chile and Uruguay and their repercussions on the debate surrounding progressive tax reforms to fund social schemes.     

The Stability of 4-Chloromethcathinone in Blood and Vitreous Humor

We present results of our study on the stability of 4-chloromethcathinone (4-CMC) in authentic postmortem peripheral blood and vitreous humor samples. The stability of 4-CMC was determined in postmortem blood samples (for a period of 90 days) and vitreous humor (30 days) at three different temperatures: −15°C, +4°C, and + 23°C. The analyses were carried out using ultra-high-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry (UHPLC-QqQ-MS/MS). In both materials, the lowest 4-CMC stability was demonstrated at room temperature. The blood samples stored in a freezer (−15°C) showed stability for the entire study period (90 days), while in the case of the vitreous humor sample stored at the same temperature the concentration of the substance decreased by 53% after 30 days. The study carried out in authentic postmortem blood and vitreous humor samples confirms the previous reports of 4-CMC instability in biological material. Authors suggest that the biological material should be stored frozen until analyses are carried out as soon as possible after collection of the material.

Does it pay to break male gender stereotypes in advertising? A comparison of advertisement effectiveness between the United Kingdom,Poland and South Africa

Advertisers shy away from using non-traditional (vs. traditional) male gender portrayals even though theory suggests they may be more effective cross-nationally. Two main hypotheses were tested cross-nationally for the first time. H1: ‘paternalistic’ male stereotypes (e.g. Househusband) would be more effective than ‘envious’ male stereotypes (e.g. Businessman) across countries confirming the stereotype content model (SCM). H2: the match between initial male gender role attitudes and advertisement type would increase advertisement effectiveness only in countries with relatively low egalitarian norms (i.e. Poland and South Africa). A cross-national study was conducted through the use of student samples following a 3(country: United Kingdom, Poland and South Africa) × 2(advertisement type) × (gender attitude) mixed design (N = 373). A three-way multivariate analysis of variance showed support for H1 and partial support for H2 (i.e. the second hypothesis held on purchase intent and for South Africa). The study provides evidence for the cross-national applicability of the SCM to advertising and the limited predictive value of gender attitudes for purchase intent depending on country. Thus, contrary to mainstream advertising practices, breaking male gender stereotypes does appear to pay cross-nationally. Theoretical and practical implications alongside the potential for change in practices are discussed.     

Relationships Between Family Connectedness and Body Satisfaction: A Longitudinal Study of Adolescent Girls and Boys

The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774 (52% female) adolescents. Participants (10–15 years of age at Time 1) completed self-report measures at three measurement occasions separated by 1 year each. Mean group difference results showed that both body satisfaction levels and perceived levels of family connectedness decreased over 2 years for the whole sample. As expected, girls were generally less satisfied with their bodies than boys, particularly in the older cohort. Structural equation modelling was used to assess stability coefficients and cross-lagged effects, and longitudinal bidirectional effects between perceptions of family connectedness and body satisfaction were found for girls, but not for boys. This result suggests that adolescent girls’ body satisfaction is both affected by and a predictor of perceived family connectedness.     

Leviathan resists: the endogenous relationship between privatization and firm performance

Using a panel dataset of privatized cement firms in Turkey, this paper models and finds support for the simultaneous relationship between privatization and firm performance. It is found that favorable short-run performance, weak market potential, higher employment, lower socio-economic development, concentrated voter preferences, and weaker representation of right-wing parties in the firms’ locality delay the timing of privatization. The paper also finds that privatization increases output in the medium-term by reducing the labor stock and promoting the adoption of more advanced technology, such that production shifts from constant to decreasing returns to scale.
