Differential attrition rates and active parental consent.

Active parental consent in survey research poses ethical and practical concerns. One common argument against the requirement of active consent procedures is its effect on participation rates. There is additional concern that higher risk groups may be underrepresented in the final sample. Empirical support of differential attrition, however, is lacking. In the current multisite longitudinal study, passive consent procedures were approved for the collection of pretest data. For subsequent years of data collection, active parental consent procedures were required. In this article, we use the pretest data to examine demographic, attitudinal, and behavioral differences between those students for whom active consent was provided and those for whom active consent was either denied or for whom no response was received. The results indicate that active consent procedures produce deleterious effects on participation rates and lead to an underrepresentation of at-risk youth in the sample.     

The rhetoric versus the reality: a critical perspective on practice with fathers in child care and protection work

Within social work training and practice there is a firm emphasis on anti-discriminatory practice. At the same time, however, fathers are often marginalized or ignored in child protection practice. In suggesting a framework for practice we argue that it is essential to address the anomaly between the rhetoric and the reality of such practice if we are to provide a coherent child protection service. This paper addresses the limitations of current models of practice and traces the theoretical strands that influence them. It is essential that social work practitioners understand the role terms they use and the aim of engaging fathers. By beginning to unravel the differences between role and gender and unpicking the diverse (but overlapping) dimensions of fatherhood, it is contended that there is no definitive, dominant discourse regarding fatherhood in the same way as there is about motherhood. However, in conceptually recognizing these roles it is suggested that intervention can be planned in a way that explicates the specific aim of engaging men.     

How Adult Learners Make Sense of Their Dyslexia

Although dyslexia was officially recognised as a disability in the 1995 Disability Discrimination Act, more widespread awareness of hidden disabilities has often been and remains problematic. Comparatively little has been written about the experiences of dyslexic adults; this paper aims to demonstrate that the non-recognition of dyslexia has been inherently disabling for one group of adult learners who participated in focus group research after attending a cycle of evening classes provided for adult dyslexic students. The concept of recognition is analysed in detail in a number of ways: the official recognition or 'diagnosis' of dyslexia and the consequences of labelling in primary and secondary education; the effects of non-recognition; recognition of dyslexia in wider society and the media; and, finally, the importance to them of recognition and understanding in their personal contexts.     

EXPERIMENTAL INVESTIGATION OF PRIORITY SCHEDULING IN A BANK CHECK PROCESSING OPERATION

This paper reports on a simulation study which was undertaken to determine if float could be significantly reduced by altering a bank's check-processing priority assignments. Float, the dollar value of check payments not yet collected from parent banks, represents a significant opportunity cost in terms of lost interest income to receiving banks. The study consisted of a comparison of a major city bank's present checksorting decision rules based on minimization of check handling, versus a proposed sorting scheme based on dollar magnitudes of checks. The reults of the research indicated that float could be substantially reduced and interest income increased by employing the proposed priority of scheduting rules.

Beyond excellence: Extending the generic approach to international public relations: The case of Bosnia

This article extends the generic approach to international public relations research. The current generic approach, based on the Excellence theory of public relations, suggests a normative framework to study and evaluate international public relations practices. This generic approach has great potential for focusing international research and clarifying infrastructure, geopolitical, legal, cultural, media, and other important variables. Unfortunately, this generic approach has been mainly used to confirm the Excellence model of public relations. Thus, it falls short of providing scholars and practitioners the tools they need to conduct and study global public relations. This paper seeks to clarify international public relations research by explicating rhetorical generic theory (RGT).     

The dynamics of laboratory populations ofCallosobruchus chinensis andC. Maculatus (Coleoptera: Bruchidae) in patchy environments

Summary Experiments are described showing the long-term dynamics of two species of bruchid beetles (Callosobruchus chinensis andC. maculatus) in arenas in which the resource of 50 black-eyed beans is divided between 5, 10 or 50 ‘patches’. Both species of adult beetles exhibit clumped distributions between patches. Within a patch there is a tendency for a density dependent reduction in (1) eggs laid per female, (2) the proportion of eggs hatching per bean (C. chinensis only) and (3) larval survival which is strongly overcompensating (particularly inC. maculatus). A discrete generation model is used as a framework to draw these results together and show how the different factors affecting natality and mortality can influence the population dynamics. Finally, the importance of the resource renewal interval in influencing the period of the population cycles is discussed.
