Is There a Stabilizing Selection Around Average Fertility in Modern Human Populations?

Possibly the greatest challenge for an evolutionary explanation of demographic transition is the fact that fertility levels universally start to fall first among the well‐to‐do, well‐educated, healthy classes, which can be explained only by some voluntary or at least adaptive action. The problem of how restraints on fertility could have evolved by natural selection has been tackled with group selection models as well as with stabilizing selection models. The latter model, which is critically discussed in this article, posits that some intermediate (rather than maximal) level of fertility is optimal for long‐term reproductive success. Tests of stabilizing selection in human populations are rare, their results inconclusive. Here four sets of data are analyzed: they are samples drawn from the 'class of 1950 of the US Military Academy at West Point (cohorts 1923–29), retired US noncommissioned officers (cohorts 1913–37), and western German and eastern German physicians (cohorts 1930–35), all containing fertility data over two generations, and from European royalty (cohorts 1790–1939) containing fertility data over four generations. Deterministic as well as stochastic fitness measures are used. It is found that maximal, not average, fertility in the first generation leads to maximal long‐term reproductive success. Also against prediction, no decreasing marginal fitness gains by increasing fertility can be observed. The findings leave little space for considering stabilizing selection as a plausible mechanism explaining the course of demographic transition but indicate instead that biological evolution today is as fast and vigorous as ever in human history. Even in large populations, all people living today may be the descendants of just some few percents—a much smaller proportion than generally believed— of the people living some generations ago.     

Is There a Link Between Poverty and Food Security?

The study examines cointegration and causal relationship between FDI, terrorism and economic growth in Pakistan using quarterly frequencies for the period 1988–2010. For empirical analysis data is divided into two sub-periods i.e. pre 9/11 (1988–2001) and post 9/11 (2002–2010) periods. The results show that long run cointegration holds between FDI, terrorism and economic growth. Granger causality results indicate that there is bidirectional short and long run causality between economic growth and FDI for both sub-samples. These findings are supported by variance decomposition and impulse response analysis. The findings suggest applicability of modernization theory to explain FDI and economic growth relationship. The results also reveal that terrorism has a deteriorating impact on FDI.     

Is There a Trade-off Between Parent Care and Self-care?

Caregiving for family members is often described as a 36-hour day. Previous literature has suggested that family caregivers have little time to attend to their own health needs, such as participating in leisure-time physical activity. Using data from the Health and Retirement Study, we analyze whether time-allocation decisions reflect a conflict between time devoted to informal care and time devoted to self-health promotion through physical activity. The empirical model is a system of four correlated equations, wherein the dependent variables are hours spent caregiving, frequency of moderate and vigorous physical activity, and hours spent in paid work. Results from joint estimation of the four equations indicate limited evidence of a competition between time spent in caregiving and frequency of physical activity. Parental factors that increase allocation of care time to parents do not comprehensively induce reductions in the frequency of any type of physical activity, or in hours of work, among either men or women.     

Is Social Capital a Good Concept?

This paper explores whether the concept of social capital as popularized by Robert Putnam is a good social science concept. Taking Gerring’s work on concept evaluation as the starting point, the paper first presents a set of criteria for conceptual ‘goodness’ and discusses how social capital performs on these criteria. It is argued that social capital eventually may be a good concept if it can be shown empirically to be a unidimensional concept. An empirical section therefore explores the validity of the unidimensionality assumption and rejects it in four separate tests at both the individual and aggregate level. We conclude that even if social capital has been a remarkably productive idea, it is not a good concept as most popular conceptualizations define social capital as several distinct phenomena or as phenomena that already have been conceptualized under other labels.     

Spiritual Struggles and Psychological Distress: Is There a Dark Side of Religion?

A growing literature examines the correlates and sequelae of spiritual struggles. Particular attention has been focused on three specific types of such struggles: (a) divine, or troubled relationships with God; (b) interpersonal, or negative social encounters in religious settings; and (c) intrapsychic, or chronic religious doubting. To date, however, this literature has focused primarily on one or another type, leaving open the possibility that these are highly correlated and may tap a single, underlying dimension. Further, because studies have relied mostly on small, specialized samples, it is not clear whether the associations between spiritual struggles and psychological functioning vary across key subgroups in the US population. Using data from the 1998 NORC General Social Survey we address these issues. Findings reveal strong and independent associations between each type of spiritual struggle and psychological distress, and they also show that these patterns are robust across most population subgroups, except for variations by age and marital status. Implications, study limitations, and directions for further research are identified.     

Student Degree Program and Attitudes Toward Gays and Lesbians in the Military: Is There a Connection?

Individuals routinely experience discrimination based on sexual orientation. Since the implementation of Don't Ask, Don't Tell in 1994, over 13,000 military personnel have been discharged from the U.S. military on the basis of sexual orientation. As helping professionals, social workers will often provide services to returning gay and lesbian veterans. Therefore, social work programs must ensure that students develop positive attitudes toward and understanding of the needs presented by this population. Little is known about whether a specific degree program can be a predictor of student attitude toward gay and lesbian individuals in the military. Eighty-nine graduate students completed the Attitudes Toward Homosexuals in the Military (ATHM) scale, and scores were compared between two graduate degree programs: Social Work and Business Administration. A statistically significant relationship was found between degree program and ATHM scores. Implications for policy, practice and research related to gay and lesbian veterans are discussed.     

The Stages of Human Capital and Economic Growth: Does the Direction of Causality Matter for the Rich and the Poor?

This paper demonstrates that key models of human mobility across several disciplines can be considered as specific cases of a broader conceptualisation of mobility in terms of its contribution to wellbeing. It is argued that this wellbeing perspective offers important advantages for the formulation of policy in areas that must respond to mobility in cross-cultural contexts, and particularly in regard to policy relating to highly mobile, indigenous peoples. An applied example is provided through a discussion of how this conceptualisation of mobility offers a different understanding of the mobility of Aboriginal and Torres Strait Islander Australians, one that may have led to superior policy outcomes.

Does Cultural Capital Matter?: Cultural Divide and Quality of Life

Since the remarkable work of Pierre Bourdieu, the concept of cultural capital has gained wide popularity along with theoretical and conceptual debates. This trend represents the social-structural change from materialism to postmaterialism. However, there are few empirical studies which find the cause and effect of cultural capital. Based on empirical survey data, this paper will analyze “how cultural capital and cultural divide influence the subjective well-being at the individual level.” Our analysis includes the following: First, we explore to what extent the cultural divide between haves and have-nots of cultural capital has impacted their subjective well-being, which consists of happiness and life satisfaction at the individual level. Second, we analyze what factors cause those cultural divides. Sociodemographic, social-relational, and economic variables are included in the regression models to test their relative explanatory power. Third, we discuss the implication for cultural policy.     

Measuring Interprovincial Flows of Human Capital in China: 1995–2000

This study measures the consequences of interprovincial migration in China in terms of the flows of human beings and the flows of human capital using two micro datasets. First, this study uses a household income survey dataset to estimate the earning returns to education as one of the two measurements of human capital. Then, the micro-dataset of the 2000 Chinese Census is used to calculate the flows of human capital among provinces by using the results from the estimation of human capital. The flows of human capital are then compared to the flows of human beings to see whether they go in the same directions and to the same extent. The results indicate that although in most of the cases, the flows of human beings and the flows of human capital are in the same directions, there are some cases that a province experienced a loss in human beings but a net gain in human capital, or vice versa. Second, some provinces are more adversely affected by the flows of human capital than others, which may not be seen by merely examining the flows of human beings. Third, non-hukou migration is different from hukou migration in volume, in scope of both gains and losses of human beings and human capital, and in directions for some provinces. Finally, we can conclude that measuring the flows of human capital is a useful way to observe how migration affects the potential of regional distribution of development.

Does Human Capital Raise Earnings for Immigrants in the Low-Skill Labor Market?

We use monthly Survey of Income and Program Participation data from 1996–1999 and 2001–2003 to estimate the determinants of differentiation in intercepts and slopes for age/earnings profiles of low-skill immigrant and native male workers. Our findings provide further depth of understanding to the“mixed” picture of earnings determination in the low-skill labor market that has been reported by others. On the positive side, many immigrants are employed in similar occupations and industries as natives. Both groups show substantial wage gains over time and generally receive similar returns to years of schooling completed. Immigrants also receive substantial returns to acculturation, measured as age at arrival and English language skill. These results cast doubt on the strong version of segmented labor market theory, in which low-skill immigrants are permanently consigned to dead-end jobs with no wage appreciation. On the negative side, immigrants earn approximately 24% less than natives and are less likely to occupy supervisory and managerial jobs. Latino immigrants receive lower returns to education than do white immigrants. Furthermore, age at arrival and language ability do not explain the lower returns to education experienced by Latino immigrants. These results suggest that Latino immigrants in particular may suffer from barriers to mobility and/or wage discrimination. Whether these negative labor market experiences occur primarily for illegal immigrants remains unknown.     

Is There Evidence of Birth Control in Late Imperial China?

In recent publications James Lee, Wang Feng, Cameron Campbell, and Zhongwei Zhao argue—contrary to what has long been the view of most sinologists—that people in late imperial China deliberately controlled their fertility through a combination of late starting, early stopping, and long spacing. The present article challenges this argument and the data offered in its support. It attempts to show that though they did not want as many children as possible, most Chinese couples did want to raise as many sons as possible. What is interpreted by the revisionists as evidence of birth control is better understood as evidence of poverty.     

Social Capital and Migration: How do Similar Resources Lead to Divergent Outcomes?

This article investigates how migrant social capital differentially influences individuals 'migration and cumulatively generates divergent outcomes for communities. To combine the fragmented findings in the literature, the article proposes a framework that decomposes migrant social capital into resources (information about or assistance with migration), sources (prior migrants), and recipients (potential migrants). Analysis of multilevel and longitudinal data from 22 rural villages in Thailand shows that the probability of internal migration increases with the available resources, yet the magnitude of increase depends on recipients' characteristics and the strength of their ties to sources. Specifically, individuals become more likely to migrate if migrant social capital resources are greater and more accessible. The diversity of resources by occupation increases the likelihood of migration, while diversity by destination inhibits it. Resources from weakly tied sources, such as village members, have a higher effect on migration than resources from strongly tied sources in the household. Finally, the importance of resources for migration declines with recipients' own migration experience. These findings challenge the mainstream account of migrant social capital as a uniform resource that generates similar migration outcomes for different groups of individuals or in different settings. In Nang Rong villages, depending on the configuration of resources, sources, and recipients, migrant social capital leads to differential migration outcomes for individuals and divergent cumulative migration patterns in communities.

Space,Context, and Human Capital: A Micro–Macro Perspective on the Social Environment and Financial Literacy in Later Life

Despite a large body of literature documenting the association between individual characteristics and financial literacy, our understanding of the impact of macro-environmental conditions on individual financial literacy remains limited, particularly in later life. Drawing from a micro–macro perspective on the social environment and individual processes, we examined the extent to which three state-level contextual characteristics were associated with individual financial literacy: tertiary educational attainment, poverty prevalence, and Internet penetration. We utilized data from the Understanding America Study for adults aged 50 years or older to assess financial literacy and data from the American Community Survey to evaluate contextual conditions. Cross-sectional multilevel regression models were used to examine the hypothesized effects. We found that state-level poverty prevalence was negatively associated with individual financial literacy, while state-level Internet penetration was positively associated with individual financial literacy, over and above individual characteristics known to impact financial literacy. No association was found between state-level educational attainment and individual financial literacy after controlling for respondents’ own education. Findings suggest that the social environment may condition older adults’ financial literacy through exposure to opportunities that promote knowledge acquisition. Interventions to enhance older adults’ financial literacy may benefit from targeted approaches that take into account the environmental characteristics of their locations of residence.

     

The Extent of Economic Vulnerability in the Canadian Labour Market and Federal Jurisdiction: Is There a Role for Labour Standards?

This paper characterizes vulnerable workers in Canada and the federal jurisdiction, based upon characteristics such as employment status, demographic characteristics, and job characteristics, and identifies areas in which labour standards may have a role. Based on this analysis, the paper evaluates the potential for labour standards to address economic vulnerability, focusing on labour standards policies aimed at wages and benefits, hours, and employment arrangements. In addition, the analysis considers the extent to which labour standards are likely to reach vulnerable workers. The results suggest several potential roles for labour standards and highlights policy implications.

All in the Family: How Do Social Capital and Material Wellbeing Affect Relational Wellbeing?

We use a unique dataset from Italy to investigate the impact of socioeconomic characteristics and social capital on family wellbeing and satisfaction. We assess wellbeing using four dimensions of satisfaction with family life: satisfaction with decision making processes, with relationships with partner and children, and with time spent with children. Social capital is measured through information about membership in organizations, trust, and interactions with others. We find that while socioeconomic characteristics in general do not have strong effects on family wellbeing, social capital matters for family life satisfaction.

     

Tolerance Within Community: Does Social Capital Affect Tolerance?

Credit cooperatives are financial intermediaries that pay attention to social criteria. Thus, if such entities want to survive and thrive in the new international context, they cannot ignore their inefficiencies in both the financial and social dimensions of their activity. However, previous research on efficiency in credit cooperatives is very limited and only considers their financial activity. To date, no study has been published giving evidence through indicators on whether these banking institutions are socially efficient. This paper therefore constructs a social efficiency index of Spanish credit cooperatives during the period 2008–2014 and examines its main explanatory factors. After applying a two-stage Data Envelopment Analysis approach, the results from the first stage indicate that, on average, the social efficiency of Spanish credit cooperatives reaches an acceptable level of 66.42 %. Second-stage truncated regression reveals that entities with a greater proportion of branches in urban areas are socially less efficient, whereas both their size and the number of service points have a positive effect. Interestingly, social efficiency also varies significantly depending on the regional location of credit cooperatives in Spain. As a result, our findings enable these Social Economy financial institutions to both know their performance relative to their social activity and use this information to improve their competitiveness in the future.
