Economic Hardship and Family-to-Work Conflict: The Importance of Gender and Work Conditions

Using data from a 2007 national survey of working Americans, we examine the association between economic hardship and family-to-work conflict (FWC). We also assess contingencies of this association, focusing particularly on gender and several work conditions. Findings indicate that economic hardship is associated with higher FWC; this pattern is stronger among men. Three work conditions also function as effect modifiers: The positive association between hardship and FWC is stronger for workers with less job authority and more creative work activities. Job pressures also modify this association, but overall, respondents with higher pressures report greater FWC. We discuss how our observations contribute to knowledge about the links between economic conditions and the family–work interface and the importance of status and work-related contingencies.     

Overconfidence in tournaments: evidence from the field

This paper uses a field survey to investigate the quality of individuals’ beliefs of relative performance in tournaments. We consider two field settings, poker and chess, which differ in the degree to which luck is a factor and also in the information that players have about the ability of the competition. We find that poker players’ forecasts of relative performance are random guesses with an overestimation bias. Chess players also overestimate their relative performance but make informed guesses. We find support for the “unskilled and unaware hypothesis” in chess: high-skilled chess players make better forecasts than low-skilled chess players. Finally, we find that chess players’ forecasts of relative performance are not efficient.     

EF-based strategies for productivity improvements at wet-etch stations

Abstract

In complex manufacturing environments, Cycle Time (CT) reductions obtained at critical production steps could generate considerable productivity improvements and lead to capacity increases at no investment costs. A wet-etch station operating in a real semiconductor manufacturing plant has been modelled to investigate the impact of different assignment strategies on CT performance. Assignment strategies based on the “Earliest Finish” (EF) concept have been developed and their productivity efficiency compared with a workload balance-based strategy. The EF-based strategies differ from each other for both computational complexity and amount of real-time information required. Encouraging results obtained for a high detail level EF strategy have inspired the development of conceptually similar strategies characterised by reduced implementation efforts. Fundamental implementation constraints, suggested by the manufacturing engineers familiar with the wet-etch station, have been taken into account throughout the different stages of this study. CT reductions ranging between 11% and 28% could be achieved at the modelled wet-etch station.     

The Euclidean distance classifier: an alternative to the linear discriminant function

The sample linear discriminant function (LDF) is known to perform poorly when the number of features p is large relative to the size of the training samples, A simple and rarely applied alternative to the sample LDF is the sample Euclidean distance classifier (EDC). Raudys and Pikelis (1980) have compared the sample LDF with three other discriminant functions, including thesample EDC, when classifying individuals from two spherical normal populations. They have concluded that the sample EDC outperforms the sample LDF when p is large relative to the training sample size. This paper derives conditions for which the two classifiers are equivalent when all parameters are known and employs a Monte Carlo simulation to compare the sample EDC with the sample LDF no only for the spherical normal case but also for several nonspherical parameter configurations. Fo many practical situations, the sample EDC performs as well as or superior to the sample LDF, even for nonspherical covariance configurations.     

Quality Assurance in Social Work Education: A Comparison of Outcome Assessments across the Continuum

Abstract

Although assessing program outcomes has become increasingly important in higher education, no systematic research has been undertaken to determine the outcome measurement systems used across the entire continuum of social work education. This study, based on a 1992 survey of more than 150 baccalaureate, master's, and doctoral social work education programs, is the first to provide substantive data about the types of assessment systems in place at all three levels. It describes the frequency of use of various systems, makes comparisons across the levels of education, and discusses the implications for social work education at each level.     

A profile of the non-profit sector in Romania

With the revolution of December 1989, citizens of Romania gained the right to form non-profit organisations for the first time in 40 years. Since then, Romania has begun to explore the frontiers of private initiative through the introduction of non-profit, non-governmental organisations as well as profit-making businesses. In this article we review the historical development and legal framework of Romania's emerging non-profit sector. We also provide the first empirical snapshot of that sector by applying the International Classification of Nonprofit Organizations (ICNPO) developed by Salamon and Anheier to 499 organisations identified in theSoros Catalogue of Nongovernmental Organizations in Romania: 1991–92. Finally, we speculate on the future development of the Romanian non-profit sector by considering alternative scenarios involving the relationships between indigenous nonprofits, international NGOs and the Romanian government.     

Population momentum expresses population aging

Population momentum and population aging occur when an initially growing population experiences a reduction in fertility to replacement level. Conceptually and empirically, momentum and aging express the same change, albeit on different scales. Fundamentally, they are two manifestations of the underlying process of demographic transformation. We consider three measures of aging over the transition to stationarity: the increase in mean population age, the decrease in the proportion under age 30, and the increase in the proportion over age 65. The three measures of aging are highly correlated, though the relationship to momentum is weakest for the increase in the proportion over age 65. We find that momentum is linearly related to aging. In both model and actual populations, a one-year increase in mean age translates into about 4.5% more population growth. The population below age 30 does not grow over the transition to stationarity, and the ratio of initial to ultimate proportions under age 30 is virtually identical to momentum.     

The Role of Parent and Peer Support in Predicting Adolescent Depression: A Longitudinal Community Study

This study examines whether perceived parent support, peer support, and the interaction between them predict depression symptoms and depression diagnosis 2 years later in a community sample of 389 adolescents. Controlling for Time 1 depression, parent support and anticipated peer support were not independently related to Time 2 depression in either linear or logistic regression analyses. However, there was a significant interaction between the two support variables, suggesting that parent support moderates the relationship between anticipated peer support and depression symptoms and diagnosis. Anticipated peer support is protective among adolescents with high parental support, but may act as a risk factor for adolescents with low parental support. Regarding developmental differences, low anticipated peer support at Time 1 was a stronger predictor of Time 2 depression symptoms among older, compared with younger, adolescents. These findings highlight the importance of parent and peer support in predicting future depression among community adolescents.
