Intergenerational transmission of longevity is not affected by other familial factors: evidence from 16,905 Dutch families from Zeeland, 1812-1962

ABSTRACT

Studies have shown that long-lived individuals seem to pass their survival advantage on to their offspring. Offspring of long-lived parents had a lifelong survival advantage over individuals without long-lived parents, making them more likely to become long-lived themselves. We test whether the survival advantage enjoyed by offspring of long-lived individuals is explained by environmental factors. 101,577 individuals from 16,905 families in the 1812–1886 Zeeland cohort were followed over time. To prevent that certain families were overrepresented in our data, disjoint family trees were selected. Offspring was included if the age at death of both parents was known. Our analyses show that multiple familial resources are associated with survival within the first 5 years of life, with stronger maternal than paternal effects. However, between ages 5 and 100 both parents contribute equally to offspring’s survival chances. After age 5, offspring of long-lived fathers and long-lived mothers had a 16-19% lower chance of dying at any given point in time than individuals without long-lived parents. This survival advantage is most likely genetic in nature, as it could not be explained by other, tested familial resources and is transmitted equally by fathers and mothers.     

Environmental predictability influences the relationship between virtues and antisocial/delinquent behavior

ABSTRACT

Despite the notion that characterizes criminals as lacking virtues or character strengths, evidence shows that people who engage in antisocial and delinquent behavior are not dissimilar in possessing character strengths as compared to the general population. Character strengths may be used to either do ‘good’ or ‘wrong’; so that the question is, what situation does direct this use to either choice? This study hypothesized environmental predictability may influence a person using their character strengths to inhibit antisocial or delinquent behavior. Two samples were examined, one consisting of individuals convicted of a criminal offense, and the other composed of non-convicted participants. Individuals responded to a series of instruments targeting virtues and character strengths, antisocial and delinquent behaviors, and environmental predictability in their environment –inferred from life-history strategy. In both groups, virtues were negatively and significantly associated with antisocial/delinquent behavior. A further test of the moderating and mediating influence of environmental predictability showed that this environmental dimension modified the aforementioned relationship, decreasing the inhibitory influence of virtues on antisociality. This means that, in predictable contexts, possessing (or lacking) character strengths is not important to inhibiting antisocial behaviors; however, in unpredictable environments virtues are useful to prevent antisociality and delinquent behavior.     

Is cooperation cost reducing? An analysis of public–public partnerships and inter-municipal cooperation in Brazilian local government

ABSTRACT

In local government systems worldwide, financial pressures have obliged local authorities to focus on cost-efficient methods for providing local services, including inter-municipal agreements and public–public partnerships. However, in comparison with municipal mergers, privatisation and other approaches to the problem, the cost impact of the cooperative provision has not yet been thoroughly examined empirically. Moreover, available empirical research has largely concentrated on waste disposal in developed countries. The present paper seeks to contribute to the empirical literature on inter-municipal agreements and public–public partnerships by comparing their impact on costs with ‘stand-alone’ provision in a range of non-waste local services. In contrast to the bulk of existing studies, our analysis takes place in a developing country context by examining Brazilian local government over the period 2013/15. We found that – on the whole – cooperative provision is less expensive than the ‘stand-alone’ provision for the services studied. Our results can be explained by the size and composition of the population, together with the politics for cooperation.     

Pulp volume quantification methods in cone-beam computed tomography for age estimation: A critical review and meta-analysis

The secondary dentin deposition that occurs after the tooth formation process results in a decrease in pulp cavity volume in adolescents and adults. The purpose of this critical review was to correlate pulpal and/or dental volume on cone-beam computed tomography (CBCT) with chronological age approximation. A subobjective was to investigate which methodology and CBCT technical parameters would be most appropriate to evaluate this correlation. This critical review followed the PRISMA guidelines, and it was conducted by a search through PubMed, Embase, SciELO, Scopus, Web of Science, Cochrane Library databases, as well as gray literature. Primary studies that used pulp volume, or pulp chamber to tooth volume ratio measured using CBCT were included. Seven hundred and eight indexed and 31 non-indexed records were identified. A qualitative analysis was performed including 25 selected studies with a total of 5100 individuals, age ranging from 8 to 87 years without sex predilection. The most used method was pulp volume/tooth volume. CBCT voxel size ranged between 0.09 and 0.5. Manual segmentation associated with threshold algorithms was used in most of the studies. Correlation between the pulp volume/tooth volume ratio was moderate: −0.66 for the upper central incisors, −0.59 for upper canines and −0.56 for lower canines. High heterogeneity was observed among the studies. It is concluded that pulp volume should be used with caution in age estimation. Evidence supports the preferable use of upper incisors with pulp volume/tooth volume ratio for age estimation. There is not enough evidence that voxel size interferes in age estimation by pulp volume.     

Does media freedom improve government effectiveness? A comparative cross-country analysis

Government effectiveness could be explained by the level of well-informed electorate members, who use the press to learn more about politicians and public servants. Thus, a free press may improve citizens’ accessibility to this information, which in turn will make it more difficult for politicians and public servants to cover up or get away with corrupt behaviour, so the quality of the government could be affected by the media freedom. Accordingly, the main aim of this paper is to determine the effect of the freedom of the press on government effectiveness, considering additionally environmental, institutional, and political characteristics as factors that could determine the level of government effectiveness. To achieve this aim, we examined 202 central governments and compared them across countries using the World Bank data set of Governance Indicators for 2002–2008. The results show that the media, the organizational environment, and political characteristics may be determinants of the level of government effectiveness, taking countries’ economic development into account.     

The Europeanization of social movements in the Czech Republic: The EU and local women’s groups

The goal of this paper is to analyze the impact the EU has had on Czech women’s groups since the 1990s. Drawing on both Europeanization and social movement theories, the first section defines the theoretical framework of the paper. The second section is focused on the impact of changes in the funding of women’s groups which, since the end of the 1990s, have relied more than before on European funding. The third section analyzes the shift in the political context and the domestic political opportunity structure in the Czech Republic that has occurred in connection with the accession process. The fourth section analyzes transnational cooperation for which new opportunities have appeared with the EU’s eastward expansion. The paper concludes by summarizing its main findings.
