Job Mobility and Early Career Wage Growth of White,African‐American,and Hispanic Women*

Objective. This article examines whether and how young women's job mobility influences racial and ethnic wage‐growth differentials during the first eight years after leaving school. Methods. We use the NLSY‐79 Work History File to simulate the influence of job mobility on the wages of skilled and unskilled workers. Results. African‐American and Hispanic women average less job mobility than white women, especially if they did not attend college. Unskilled women who experience frequent job changes during the first four postschool years reap positive wage returns, but turnover beyond the shopping period incurs wage penalties. Job mobility does not appear to boost wage growth for college‐educated women. Conclusions. Among unskilled women, race and ethnic wage disparities partly derive from group differences in the frequency of job changes, but unequal returns to job mobility drive the wage gaps for skilled women. We discuss several explanations for these disparities.     

Pollutant Ground Concentrations of Nonneutrally Buoyant Particles

A methodology is suggested for the estimation of the mass density and the cumulative ground deposition of a nonvolatile, nonneutrally buoyant, air pollutant (liquid or solid) released from a polluted column (following an explosion caused during routine operation in, e.g., the chemical industry or due to any kind of hostile act) and deposited on the ground via gravitational settling. In many cases, the deposited mass due to gravitational settling constitutes a significant fraction of the original inventory released from the source. Implementation of the methodology in preliminary risk assessments can serve as an efficient tool for emergency planning for both immediate and long‐term measures such as evacuation and decontamination. The methodology considers, inter alia, an estimation of the critical particle diameter, particle size, and mass distributions along the polluted column. This methodology was developed to apply in rural regions since proper application of relevant meteorological input data can be accomplished mainly for such areas.     

Flexible work planning of service agents with load balancing

This work emerged from the need to better plan the daily work of 29 travelling service agents, who provide 1090 services to 412 customers in 283 sites, on daily average. A handy and flexible tool was developed and is presented herein. A major contribution of this study is an explicit consideration of the multi-dimensional nature of the problem by the inclusion of workload balancing, which may stand in conflict to cost minimisation. Further, the geographical distribution of the demand is highly irregular. Therefore, two load measures are required and balanced. This required to fitting a proper planning scheme. The planning tool has been applied successfully by the commercial service provider. Improvements in the order of 20% and more were obtained in key performance measures. Moreover, cost reductions, service improvement and load balance were obtained simultaneously: the standard deviations of the service times and working day’s duration were reduced by 18 and 58%, respectively. This enables to reduce the number of agents with no significant harm in performance. Additional practical advantages of the proposed tool are also discussed and demonstrated, for example, the ability to cope with geographical distributions and the flexibility to respond to daily variations in demand.     

Role of Comparative Risk Assessment in Addressing Environmental Security in the Middle East

During the 21st century, environmental challenges are likely to intensify across the world and possibly lead to violent conflicts. Strategies for conflict avoidance will be incomplete unless they recognize, discuss, and mitigate regional environmental stress factors. Comparative risk assessment (CRA) is one of the most critical tools emerging to influence modern environmental policies and is increasingly used to create a common language to help reconcile competing interests in development and environmental disputes around the world. This article considers the environmental challenges facing the Middle East in light of their "transboundary" nature and proposes CRA as a framework for setting environmental priorities and reducing tensions in the region.     

The Local Life of Nationhood

What characterises many studies that invoke the local can be described as a logic of transcendence. This logic of transcendence does not reject nor disregard the local. Rather, it affirms the centrality of the local. At the same time, the focus is on how the local is historically transcended into higher levels of generality and abstraction; the argument is that only through attention to these higher levels that the meanings of the local become clear. In contrast, the other local which we refer to in this essay is a set of practices which emerges in intimate relationship to nationalism, which in some ways even sustains nationalism, even though the places it produces cannot be understood within the same logic of transcendence. At times, this other local refers to the political and conceptual practices that emerged at the limits of the abstract time and space that constituted nationalism. At other times, this local refers to the marginal in order to represent nationhood anew. Nationhood does not exhaust, sublate or transcend this local; rather, this local continues to live, in the era of nationhood, not so much outside the national, but beyond and alongside it. This other local is explored in this essay by discussing the cases of Germany and India.     

Stigma Management Among Gay/Bisexual Men with HIV/AIDS

People with HIV infection are subjected to prejudice, discrimination and hostility related to the stigmatization of AIDS. To manage the stigma of their disease, they mount complex coping strategies. This paper reports results from a qualitative study that examined gay/bisexual men's experiences of living with HIV infection. Unstructured interviews from a diverse sample of 139 men were analyzed to examine how men coped with AIDS-related stigma. We discerned a variety of stigma management strategies that could be arranged along a continuum from reactive to proactive based on the extent to which they implicitly accepted or challenged the social norms and values that underlie the stigmatization of HIV/AIDS. Reactive strategies to cope with stigma involve defensive attempts to avoid or mitigate the impact of stigma, but imply acceptance of the underlying social norms and values that construct the stigma. Examples of reactive strategies include hiding one's HIV status, presenting one's illness as a less stigmatizing one (e.g., cancer), or distancing one's self from more damaging aspects of AIDS-stigma (e.g., attributing infection to blood transfusion). Proactive strategies challenge the validity of the stigma and imply disavowal and resistance of the social norms and values that underlie the stigma. Examples of proactive strategies include engaging in public educational efforts that address misperceptions about HIV transmission and social activism to change the social and political conditions that affect PWA/HIV.     

Structural Analysis of a Consumption-Based Stratification Indicator: Relational Proximity of Household Expenditures

This paper proposes a new analysis of consumption inequality using relational methods, derived from network images of social structure. We combine structural analysis with theoretical concerns in consumer research to propose a relational theory of consumption space, to construct a stratification indicator, and to demonstrate its analytical efficacy with aggregate consumption data. This allows us to emphasize the multi-dimensionality of the relationship between social groups and consumption patterns in the context of a stratification perspective. We utilize the concept of structural equivalence, derived from network models of social structure, to recover relational proximity between social groups and between consumption categories. Additionally, we use relational proximity to construct a new indicator of consumption hierarchy and we test its predictive ability in estimating consumption behavior. We discuss the theoretical implications of our findings for a spatial theory of stratification, as well as possible directions for future research.     

The inverse Banzhaf problem

Let ${\mathcal{F}}Let F{\mathcal{F}} be a family of subsets of the ground set [n] = {1, 2, . . . , n}. For each i ? [n]{i \in [n]} we let p(F,i){p(\mathcal{F},i)} be the number of pairs of subsets that differ in the element i and exactly one of them is in F{\mathcal{F}}. We interpret p(F,i){p(\mathcal{F},i)} as the influence of that element. The normalized Banzhaf vector of F{\mathcal{F}}, denoted B(F){B(\mathcal{F})}, is the vector (B(F,1),...,B(F,n)){(B(\mathcal{F},1),\dots,B(\mathcal{F},n))}, where B(F,i)=\fracp(F,i)p(F){B(\mathcal{F},i)=\frac{p(\mathcal{F},i)}{p(\mathcal{F})}} and p(F){p(\mathcal{F})} is the sum of all p(F,i){p(\mathcal{F},i)}. The Banzhaf vector has been studied in the context of measuring voting power in voting games as well as in Boolean circuit theory. In this paper we investigate which non-negative vectors of sum 1 can be closely approximated by Banzhaf vectors of simple voting games. In particular, we show that if a vector has most of its weight concentrated in k < n coordinates, then it must be essentially the Banzhaf vector of some simple voting game with n − k dummy voters.     

Compulsory Income Management in the Northern Territory – evaluating its impact

Australia has been experimenting with constraining the ways in which welfare recipients can spend their income support payments, limiting their ability to access cash and purchase some products. The policy objectives include to reduce spending on alcohol, gambling, pornography and tobacco in favour of meeting ‘basic’ family needs, especially for children, to limit the scope for financial harassment, encourage pro‐social behaviours, and build financial capabilities. In the logic of the programs these outcomes are expected to be manifest at the individual, family and community levels. The policy has primarily impacted on Indigenous Australians as a result of its geographic targeting, although a recent report has recommended a more stringent version of the program be introduced universally to all welfare recipients other than the aged. The largest of these experiments is ‘New Income Management’ in the Northern Territory, which has had more than 35,000 participants since its introduction in 2010. This article reports on the key findings of the major independent evaluation of New Income Management commissioned by the Australian Government.     

Missing Elements in the Protection of Children: Three Cases from China

ABSTRACT.

The article analyzes 3 severe cases of child abuse that were widely discussed in the mass media in China in 2007 based on a framework used by the International Society for Prevention of Child Abuse and Neglect in its official publication World Perspectives on Child Abuse. The framework sets out the basic elements that must be included in systems of child protection: a) a responsible government or government-authorized organization; b) a set of institutional arrangements for reporting cases of child abuse, investigation, and intervening when necessary; and c) state guardianship or mechanisms to remove children from their parents’ care when necessary. By applying the framework to the 3 cases under analysis, the authors found that these basic elements are missing from the Chinese child protection system, and therefore, they recommend that a reform of the system to address these elements should be a priority for Chinese social policy. The article makes a number of recommendations for reform.
