Creating ‘stability’ for children in step‐families: time and substance in parenting

Children are said to be in need of stability for a ‘successful’ upbringing. This article focuses on the implications of this for parenting and childrearing practices in step‐families. It addresses the ways that conceptions of stability for children in family policy are tied to a particular family form and to maintaining continuity in biological parenting obligations, while parenting research has largely been concerned with measuring the consequences of changing family forms for children. In contrast, parents and step‐parents in step‐families themselves have far more complex understandings about the creation of stability for children in their care, around issues of dis/continuity in linear time and the social and material substantive constitution of stability.

Robust designs for experiments with blocks

ABSTRACT

For experiments running in field plots or over time, the observations are often correlated due to spatial or serial correlation, which leads to correlated errors in a linear model analyzing the treatment means. Without knowing the exact correlation matrix of the errors, it is not possible to compute the generalized least-squares estimator for the treatment means and use it to construct optimal designs for the experiments. In this paper, we propose to use neighborhoods to model the covariance matrix of the errors, and apply a modified generalized least-squares estimator to construct robust designs for experiments with blocks. A minimax design criterion is investigated, and a simulated annealing algorithm is developed to find robust designs. We have derived several theoretical results, and representative examples are presented.     

Rethinking power in public relations

In the United Kingdom, popular sceptism about the merits of public relations has prompted self-reflection among practitioners and industry bodies. At the root of the public debate is the assumption that public relations wields unjustified social influence on behalf of already privileged organizational interests. The core concern of this discussion, therefore, is the power that a public relations has in democratic societies.     

Marginality and migration: cultural dimensions of the Afghan refugee problem

Given the duration of time that has passed since the Afghan refugee influx into Pakistan began and the absence of any immediate prospect for a political settlement which would allow the refugees to return home, it is necessary to consider what the long-term requirements of this population might be and the implications of permanent resettlement on both the refugees and the host country. For policy makers, these are urgent questions that must be confronted not only to help ensure the health, safety, and productive future of the refugees, but also to minimize the risks of even greater political instability in this troubled region. This article attempts to provide some basic insights into the society and culture of the Afghan refugees and will consider what impact dislocation and settlement have had specifically on tribally-organized Pakhtuns, who comprise approximately 50% of the Afghan population generally and perhaps 80-90% of the refugee population (author's).     

Organizational Legitimacy and Stakeholder Information Provision1

One interpretation of the concept of organizational legitimacy is that it stems from the cultural values of society, and suggests that businesses operate under a mandate that may be withdrawn if organizations are seen not to be doing the ‘right’ things. This suggests there is something in the nature of a principal-agent relationship in existence, and that some form of accountability is then owed by the agent (the organization) to the principal (society). This paper seeks to investigate the nature of this accountability, distinguishing between the accountability which exists towards those elements of society with which an organization has a contractual relationship, and those where it does not. Adopting a pluralist stance, stakeholder theory is then used to illustrate the possible nature of both the form of legitimacy relationship extant, and of the accountability that the principal might expect of the agent.     

Sodium cromoglicate: an ineffective drug or meta‐analysis misused?

Sodium cromoglicate (SCG) has been available since around 1970 for the treatment of asthma and other allergic disorders in both adults and children. It has been approved for use around the world. Over the period of its development, a number of different formulations were introduced. In 1999, a systematic review of SCG use in childhood asthma was carried out and reported initially as a poster. Further systematic reviews and papers followed from the same authors and finally a Cochrane Collaboration review was published in 2003. All concluded that SCG was ineffective in paediatric asthma. Both the British Thoracic Society Guidelines for the treatment of paediatric asthma and the Model List of Essential Drugs of the WHO now reflect these conclusions. This paper looks carefully at the conclusions of these systematic reviews and raises concerns about the interpretation of the results. These failed to take adequate account of the changes with time in both the formulations used and the age groups examined, and also failed to take adequate note of the totality of information available over all end-points. One primary end-point was based on only four out of the 24 studies included in the review. Rather than having no effect, it is demonstrated that a considerable body of evidence favours SCG compared to placebo and, far from being ineffective, the drug appears to be effective particularly in older children. This article replaces a previously published version. DOI: 10.1002/pst.258.     

Gambling decisions: an early intervention program for problem gamblers

An implementation and one-year follow-up of the Gambling Decisions program attempted to answer several important questions. First, is controlled gambling a viable treatment option for some gamblers? Can earlier stage problem gamblers be separated for treatment from those with more severe problems? Finally, would problem gamblers utilize a community health agency for treatment of their excessive gambling? A pretest/posttest design was chosen where the efficacy of the program was assessed using repeated measures ANOVA analysis. Results showed that an average loss of $608 over a 4-week period was reduced to $113 immediately after the 6-week program and to a loss of $73 at 12 months. The average number of hours spent gambling per 4 weeks was significantly reduced from 23.5 at pretest to 6.5 at the 12 month posttest. Significant decreases were also observed in the number of days per week that clients gambled, and clients reported significant reductions in everyday life problems related to gambling after completing the program.
