Fertility decline in Taiwan: A study using parity progression ratios

Taiwan's decline in fertility is studied by using period parity progression ratios. Levels of marriage and motherhood are found to have been high and essentially constant though the late 1980s, suggesting that the decline has been due almost entirely to declines in second and higher order-births. Families with three or more children play an important role in maintaining the current level of fertility. The level of fertility would be even lower without these families. They contributed more than one-half child per woman to the total fertility rate during most of the 1980s. Total fertility rates computed from the period parity progression ratios indicate a substantially higher level of fertility than the conventional total fertility rate; they remained above or at replacement level through 1988. A formal demographic analysis suggests that the conventional total fertility rate has been depressed by shifts in age at childbearing.     

Managing Migration,Managing Motherhood: The Moral Economy of Gendered Migration

For the past two decades, women have been migrating from Mexico to the United States on temporary work visas to pick meat from blue crabs in small coastal factories. Within a theoretical framework that argues for the relevance of a moral economic perspective to gendered migration, we examine the how participating in this migration influences migrants' families, including their abilities to produce higher‐quality lives. Specifically, we focus on the various factors that feed into the decision to migrate, the immediate consequences of those decisions for the relations among migrants, children, spouses and other family and community members, and the longer‐term consequences in terms of gender relations, the restructuring of parent–child relationships and the material benefits of work abroad. We find that women negotiate a variety of contradictions and paradoxes to participate in the programme, many of which directly influence their quest to reaffirm their abilities, as mothers, to produce quality human beings. These findings reflect more general global appeals for valuing human life by measures other than those of conventional political economy.     

Leadership, affect and emotions: A state of the science review

This paper presents a selective, qualitative review of affect, emotions, and emotional competencies in leadership theory and research published in ten management and organizational psychology journals, book chapters and special issues of journals from 1990 to 2010. Three distinct themes emerged from this review: (1) leader affect, follower affect and outcomes, (2) discrete emotions and leadership, and (3) emotional competencies and leadership. Within each of these themes, we examine theory (construct definition and theoretical foundation) and methods (design, measurement and context) and summarize key findings. Our findings indicate that the study of affect and emotions in leadership fares well with regard to construct definitions across the first two themes, but not in the last theme above. Design and measurement issues across all three themes are a little less advanced. One serious gap is in a lack of focus on levels-of-analysis theoretically and methodologically. Our review concludes with recommendations for future theoretical and empirical work in this area.     

VERTICAL INTEGRATION AND TECHNOLOGY: THEORY AND EVIDENCE

We study the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple incomplete contracts model. Then, we investigate these predictions using plant‐level data for the UK manufacturing sector. Most importantly, and consistent with the theoretical predictions, we find that the technology intensity of downstream (producer) industries is positively correlated with the likelihood of integration whereas the intensity of upstream (supplier) industries is negatively correlated with it. Also consistent with theory, both correlations are stronger when the supplying industry accounts for a large fraction of the producer's costs. These results are generally robust and hold with alternative measures of technology intensity, with alternative estimation strategies, and with or without controlling for a number of firm‐ and industry‐level characteristics.

The Moran coefficient for non-normal data

This paper summarizes findings that extend statistical distribution properties of the Moran coefficient index measuring spatial autocorrelation to non-normal random variables. Pitman–Koopmans theorem results are extended for the mean and the variance of this index. This summary includes a corollary to this theorem, as well as a new theorem (with its proof) and two conjectures implied by it. The first of these statements is supported by asymptotic heuristics; the second is supported by simulation experiment results. Mixture random variables that include heteroscedasticity or overdispersion also are explored. In addition, a simple asymptotic variance for the Moran coefficient is presented, assessed, and found to be very precise for sample sizes as small as 25–100. The principal conclusion is that independence and sample size are the most relevant properties for Pitman–Koopmans theorem results to be extended to non-normal random variables. The independent and identically distributed property reduces the necessary sample size for this extension, as do the properties of symmetry and normal approximation.     

What works for you may not work for (Gen)Me: Limitations of present leadership theories for the new generation

Scholars and practitioners alike have recognized that younger workers, collectively known as Millennials or GenMe, are different from workers in prior generations. Employees of this generation hold different expectations regarding the centrality of work to their lives and bring different personalities and attitudes to the workforce. As the number of Millennials in the workforce grows each year, the divide between them and their older counterparts becomes more salient, posing unique challenges for organizational leaders. In this paper, we explore how these changes may force the need for reconsideration of five of the most frequently used leadership theories in an effort to understand important boundary conditions and how leadership research must evolve to keep pace with a changing workforce.     

Police Crime: The Criminal Behavior of Sworn Law Enforcement Officers

This essay examines the criminological conceptualizations and research on police crime, that is, the criminal behavior of sworn law enforcement officers. It starts with an overview of the conceptualization of police crime as it relates to organizational and scholarly perspectives of social deviance. Police deviance is often conceptualized to include various misconduct, corruption, and/or crime committed by police organizations and police officers. This essay focuses on police crime resulting in the arrest of a sworn law enforcement officer and is organized within a conceptual framework that incorporates five types of police crime: sex‐related police crime, alcohol‐related police crime, drug‐related police crime, violence‐related police crime, and profit‐motivated police crime.     

Period Parity Progression Measures of Fertility in China

Parity progression measures are uniquely suited to the study of fertility in China, because Chinese policies and programmes focus so closely on parity and birth order. In this paper we present period parity progression ratios for China and its urban and rural areas for the years 1955–81, using the birth history data from the one-per-thousand fertility survey of 1982. Our period parity progression ratios differ from those introduced by Henry in that they provide an overall level of fertility which may be compared with measures based on age-specific birth rates. We compare the two measures empirically for China, finding both similarities and divergences, and then analyse the relation between them. It is suggested that, where fertility is low and fluctuating, as in China, the parity-progression-based measures provide a substantially truer picture of fertility levels and trends than do age-based measures.
