The hard and soft sides of union political money

We reach several conclusions. First, to the extent that soft money per se and issue advertising are the primary targets of campaign-finance reformists, unions contribute little, overall, to the perceived or real problem. Union soft money pales in comparison not only to total interest-group expenditures of this type but also to the hard money that labor dispenses. Moreover, with their relatively limited treasuries, unions are in no position to compete with the corporate sector. It has been estimated that the total assets of labor unions, at the combined local, regional, and national/international levels, barely exceeded $10 billion in 1995 (Masters and Atkin, 1997). Revenues were less than $13 billion.     

Voices From the Front Line: State Social Workers and New Labour

Summary The article explores the condition of state social work in Englandtoday. It is based on interviews with experienced social workersemployed by local authority social services departments acrossthe north of England. These front line state social workersprovide a penetrating insight into the diverse ways in whichtheir work has been transformed and degraded and the mannerin which the needs of clients have been largely ignored. Fromtheir perspective, the election of a Labour government in 1997proved to be a massive disappointment and many social workersreported that it has further undermined state social work practice,workers and clients. The paper seeks to offer an explanationby noting the neo-liberalism of Labour's social policy and thedire consequences which flow from New Labour's fixation withwaged work as the principal solution to social exclusion andpoverty. Above all, it seeks to provide an opportunity for theviews of front-line state social workers to be heard.     

The derivation of a brief Student Nurse Stress Index

The lack of an adequate measure of perceived sources of stress for student nurses led to the construction of the Student Nurse Stress Index (SNSI). Responses from 235 first-year student nurses to 35 items from the Beck and Srivastava Stress Inventory (Beck, and Srivastava, 1991), and 15 new items, were subjected to exploratory factor analysis using principal components analysis and oblimin rotation. A reliable 22-variable solution with a simple oblique structure including Academic load, Clinical sources, Interface worries, and Personal problems factors was obtained in this initial sample, and confirmed at an exploratory level in a further independent validation sample of 188 first-year students. Confirmatory factor analysis established the four-factor model in the first sample, but required that three variables load onto more than one factor. This more complex four-factor model was confirmed using independent data from the validation sample, and the total invariance of factor loadings and factor covariances of this more complex four-factor model was established in both data sets simultaneously using multi-sample techniques. The SNSI shows cross-sample factor congruence, good internal reliabilities, and concurrent and discriminant validity across a range of reporting conditions.     

Changing Workplaces to Reduce Work-Family Conflict: Schedule Control in a White-Collar Organization

Work-family conflicts are common and consequential for employees, their families, and work organizations. Can workplaces be changed to reduce work-family conflict? Previous research has not been able to assess whether workplace policies or initiatives succeed in reducing work-family conflict or increasing work-family fit. Using longitudinal data collected from 608 employees of a white-collar organization before and after a workplace initiative was implemented, we investigate whether the initiative affects work-family conflict and fit, whether schedule control mediates these effects, and whether work demands, including long hours, moderate the initiative's effects on work-family outcomes. Analyses clearly demonstrate that the workplace initiative positively affects the work-family interface, primarily by increasing employees' schedule control. This study points to the importance of schedule control for our understanding of job quality and for management policies and practices.     

On the asymptotic efficiency of moment and maximum likelihood estimators in the three-parameter inverse gaussian distribution

The asymptotic distribution of estimators generated by the methods of moments and maximum likelihood are considered. Simple formulae are provided which enable comparisons of asymptotic relative efficiency to be effected.     

Mathematical morphology: A useful set of tools for image analysis

In this paper we give an overview of both classical and more modern morphological techniques. We will demonstrate their utility through a range of practical examples. After discussing the fundamental morphological ideas, we show how the classic morphological opening and closing filters lead to measures of size via granulometries, and we will discuss briefly their implementation. We also present an overview of morphological segmentation techniques, and the use of connected openings and thinnings will be demonstrated. This then leads us into the more recent set-theoretic notions of graph based approaches to image analysis.
