Hypercapitalism: Language, new media and social perceptions of value

Using examples from contempoary policy and business discourses, and exemplary historical texts dealing with the notion of value, I put forward an argument as to why a critical scholarship that draws on media history, language analysis, philosophy and political economy is necessary to understand the dynamics of what is being called 'the global knowledge economy'. I argue that the social changes associated with new modes of value determination are closely associated with new media form.

Alterations in Plasmodium falciparum genotypes during sequential infections suggest the presence of strain specific immunity

Many of the asexual stage Plasmodium falciparum proteins that are the targets of host protective responses are markedly polymorphic. The full repertoire of diversity is not defined for any antigen. Most studies have focused on the genes encoding merozoite surface proteins 1 and 2 (MSP1, MSP2). We explored the extent of diversity of some of the less studied merozoite surface antigens and analyzed the degree of complexity of malaria field isolates by deriving nucleotide sequences of several antigens. We have determined the genotype of apical membrane antigen 1 (AMA1) in a group of 30 field samples, collected over 29 months, from individuals living in an area of intense malaria transmission in Irian Jaya, identifying 14 different alleles. AMA1 genotyping was combined with previously determined MSP2 typing. AMA1 had the greatest power in distinguishing between isolates but methodological problems, especially when mixed infections are present, suggest it is not an ideal typing target. MSP1, MSP3, and glutamate-rich protein genotypes were also determined from a smaller group of samples, and all results were combined to derive an extended antigenic haplotype. Within this subset of 10 patients, nine different genotypes could be discerned; however, five patients were all infected with the same strain. This strain was present in individuals from two separate villages and was still present 12 months later. This strain was predominant at the first time point but had disappeared at the fourth time point. This significant change in malaria genotypes could be due to strain-specific immunity developing in this population.

Magic happens: Revisiting the spirituality and social work debate

The social work profession is currently undergoing a resurgence of interest regarding the issue of spirituality in social work. This article attempts to summarise and explore the debate so far and to discuss the implications of this in a practice context. Current issues including definitions of spirituality and the key concerns in the areas of both practice and education are addressed. The article concludes with an overview of a model of spiritually sensitive social work practice, and poses options for further professional reflection on the place of spirituality in social work practice.

Who supports? The providers of social support to dual-parent families caring for young children

Previous research points to the importance of both kin and non-kin ties within social networks as sources of social support. This study examines the kin and non-kin providers of specific types of support to dual-parent low-income Australian families caring for young children. The study highlights the importance of family and friends as support providers. Study Participants tended to rely on family, including parents, siblings and other family members, and friends for emotional and information support. Parents also tended to provide material and practical support. While neighbors and community agencies offered some emotional and information support, overall, these sources were minimal.

Social work, stress and burnout: A review

Stress and burnout for health care professionals have received increasing attention in the literature. Significant administrative, societal and political changes have impacted on the role of workers and the responsibilities they are expected to assume. Most writers suggest that social work is a highly stressful occupation, with stress deriving in particular from role conflict between client advocacy and meeting agency needs. This article reviewed the social work literature with two questions in mind: Are social workers subject to greater stress than other health professionals? What factors contribute to stress and burnout among social workers? We found that most of the literature was either anecdotal or compared social worker stress with general population norms rather than with stress levels of workers in comparable professions. Such empirical research as is available suggests that social workers may experience higher levels of stress and resulting burnout than comparable occupational groups. Factors identified as contributing to stress and burnout included the nature of social work practice, especially tension between philosophy and work demands and the organization of the work environment. There was some evidence that supervision and team support are protective factors.
