Social Work, Social Politics and Justice

"The disaster does not primarily lie in people and in the way that they perceive the circumstances, rather in the circumstances that doom people to powerlessness and apathy - circumstances which they could, however, change" (Adorno, 1966, p. 189). When Karl Marx writes to Friedrich Sorge in his letter of the 19.10.1877, regarding his critique of the opinion of his opponents Dühring & Co., that one must deal with "a whole crowd of immature students and pompous doctors who claim to give socialism a 'higher, ideal' turn, that is to say, to replace the materialistic basis (that demands serious, objective study if one wants to operate on it)… with modern mythology by means of their goddesses of justice, freedom, equality and fraternité" (Marx, 1973, p. 303; cf. Schiller, 1993, p. 199 onwards), this thus refers to fundamental problems with the concept of "justice" up until today. As the debate shows, it concerns the contextualization of the term "justice", its meaning in historically concrete as well as socio-political circumstances, and therefore a social analysis that is both representation and critique. Essentially it also concerns the question of the relationship between ideas and reality and the development of standards of historical systematic 'nature' out of social frameworks (see Frey, 1978; Theunissen, 1989).

Social Work and a New Social Order - Challenging Neo-liberalism's Erosion of Solidarity

The world in which social work operates today is a very different world from that in which most of us took their social work training, and the changes we are facing are profound. This paper argues that these changes are not merely a regime change in social policy but that they are essentially about a re-ordering of social relationships and attempt to model them on neo-liberal ideas. In view of these pressures it is understandable that social workers often try to ignore those changes and withdraw into a private world of therapeutic relationships in which the methods they trained in are made to be still valid, or they simply go along with new service delivery designs without asking too many questions. Both reactions fail to question what the "social" can still mean in the light of these changes and how social workers can fulfil their mandate to be responsible for the social dimension of public life. Nothing less than a head-on challenge of the basic presuppositions of neo-liberalism (Willke 2003) and their manifold applications to social service delivery systems will thereby suffice.

Edna Chamberlain (1921 -2005): A Leader through Times of Transition and Change

Professor Edna Chamberlain was an outstanding leader in Australian social work. She contributed extensively to social work education at the University of Queensland, the social work profession through her leadership of the Australian Association of Social Workers and to the community through advocacy for progressive social policies. Her life experiences were influential is shaping her career and her particular teaching and research interests. Early in her life, Chamberlain was exposed to individual deprivation as a result of the Great Depression. This provided the incentive for a career in social work. She worked as a social work practitioner for some years and entered the academic world until after the death of her husband. In the university and profession, she was confronted by conflict between traditionalists and those wanting immediate reform. In managing these tensions, she tried to find the common ground but these tensions also moderated and changed her views about the purpose and practice of social work. Her rich practice and later research and teaching background provided a strong basis for her professional leadership, research activities and curriculum initiatives. Whilst social casework methods were influential early in her career she sought in later years to integrate the private pain of individuals with social policy and community planning by focusing on the purpose of social work – demonstrating her commitment to the disadvantaged in the context of social justice.

Combining follow-up and change data is valid in meta-analyses of continuous outcomes: a meta-epidemiological study

OBJECTIVE To investigate whether it is valid to combine follow-up and change data when conducting meta-analyses of continuous outcomes. STUDY DESIGN AND SETTING Meta-epidemiological study of randomized controlled trials in patients with osteoarthritis of the knee/hip, which assessed patient-reported pain. We calculated standardized mean differences (SMDs) based on follow-up and change data, and pooled within-trial differences in SMDs. We also derived pooled SMDs indicating the largest treatment effect within a trial (optimistic selection of SMDs) and derived pooled SMDs from the estimate indicating the smallest treatment effect within a trial (pessimistic selection of SMDs). RESULTS A total of 21 meta-analyses with 189 trials with 292 randomized comparisons in 41,256 patients were included. On average, SMDs were 0.04 standard deviation units more beneficial when follow-up values were used (difference in SMDs: -0.04; 95% confidence interval: -0.13, 0.06; P=0.44). In 13 meta-analyses (62%), there was a relevant difference in clinical and/or significance level between optimistic and pessimistic pooled SMDs. CONCLUSION On average, there is no relevant difference between follow-up and change data SMDs, and combining these estimates in meta-analysis is generally valid. Decision on which type of data to use when both follow-up and change data are available should be prespecified in the meta-analysis protocol.

Who stays, who benefits? Predicting dropout and change in cognitive behaviour therapy for psychosis

This study investigates predictors of outcome in a secondary analysis of dropout and completer data from a randomized controlled effectiveness trial comparing CBTp to a wait-list group (Lincoln et al., 2012). Eighty patients with DSM-IV psychotic disorders seeking outpatient treatment were included. Predictors were assessed at baseline. Symptom outcome was assessed at post-treatment and at one-year follow-up. The predictor x group interactions indicate that a longer duration of disorder predicted less improvement in negative symptoms in the CBTp but not in the wait-list group whereas jumping-to-conclusions was associated with poorer outcome only in the wait-list group. There were no CBTp specific predictors of improvement in positive symptoms. However, in the combined sample (immediate CBTp+the delayed CBTp group) baseline variables predicted significant amounts of positive and negative symptom variance at post-therapy and one-year follow-up after controlling for pre-treatment symptoms. Lack of insight and low social functioning were the main predictors of drop-out, contributing to a prediction accuracy of 87%. The findings indicate that higher baseline symptom severity, poorer functioning, neurocognitive deficits, reasoning biases and comorbidity pose no barrier to improvement during CBTp. However, in line with previous predictor-research, the findings imply that patients need to receive treatment earlier.

Social control and smoking: Examining the moderating effects of different dimensions of relationship quality

A common form of social regulation of an individual’s health behavior is social control. The contextual model of social control assumes that higher relationship quality goes along with more beneficial effects of social control on health behavior. This study examined potential differential moderating effects of different dimensions of relationship quality on the associations between positive and negative social control and smoking behavior and hiding smoking. The sample consisted of 144 smokers (n = 72 women; mean age = 31.78, SD = 10.04) with a nonsmoking partner. Positive and negative social control, dimensions of relationship quality consensus, cohesion and satisfaction, numbers of cigarettes smoked (NCS), hiding smoking (HS), and control variables were assessed at baseline. Four weeks later NCS and HS were assessed again. Only for smokers with high consensus, but not cohesion and satisfaction, a negative association between positive control and NCS emerged. Moreover, smokers with high consensus tended to report more HS when being positively and negatively socially controlled. This also emerged for cohesion and positive control. Satisfaction with the relationship did not display any interaction effects. This study’s results emphasize the importance of differentiating not only between positive and negative social control but also between different dimensions of relationship quality in order to gain a comprehensive understanding of the dynamics in romantic dyads with regard to social regulation of behavioral change.

Temporal genetic structure and relatedness in the Tufted Duck Aythya fuligula suggests limited kin association in winter

Conspecific aggregation of waterfowl in winter is a common example of animal flocking behaviour, yet patterns of relatedness and temporal substructure in such social groups remain poorly understood even in common species. A previous study based on mark-recapture data showed that Tufted Ducks Aythya fuligula caught on the same day were re-caught together in subsequent winters more often than expected by chance, suggesting stable assortments of ‘socially familiar’ individuals between wintering periods. The genetic relationships within these social groups were not clear. Based on 191 individuals genotyped at 10 microsatellite markers, we investigated the temporal genetic structure and patterns of relatedness among wintering Tufted Ducks at Lake Sempach, Switzerland, in two consecutive winters. We found no evidence of genetic differentiation between temporal groups within or between winters. The average levels of relatedness in temporal groups were low and not higher than expected in random assortments of individuals. However, Mantel tests performed for each sex separately revealed significant negative correlations between the pairwise relatedness coefficients and the number of days between the capture dates of pairs of wintering Tufted Duck in males and females. This pattern suggests the presence of a small number of co-migrating same-sex sibling pairs in wintering flocks of Tufted Ducks. Our findings provide one of the first genetic analyses of a common duck species outside the breeding season and contribute to the understanding of social interactions in long-distance migratory birds.

Using Blackboard Administered Precourse and Post course Tests to Assess Student Readiness to Learn and Change in Knowledge

Students arrive at classes with a varying social situations and course subject knowledge. Blackboard is a web based course delivery program that permits testing of students before arriving at the first class. A pretest was used to assess preexisting subject knowledge(S) and a survey was used to assess non-subject (N) factors that might impact the student’s final grade. A posttest was administered after all content was delivered and used to access change in S. [See PDF for complete abstract]

Developmental Changes in the Structure and Composition of the Postsynaptic Density

The development of the brain and its underlying circuitry is dependent on the formation of trillions of chemical synapses, which are highly specialized contacts that regulate the flow of information from one neuron to the next. It is through these synaptic connections that neurons wire together into networks capable of performing specific tasks, and activity-dependent changes in their structural and physiological state is one way that the brain is thought to adapt and store information. At the ultrastructural level, developmental and activity-dependent changes in the size and shape of dendritic spines have been well documented, and it is widely believed that structural changes in spines are a hallmark sign of synapse maturation and alteration of synaptic physiology. While changes in spine structure have been studied extensively, changes in one of its most prominent components, the postsynaptic density (PSD), have largely evaded observation. The PSD is a protein-rich organelle on the cytoplasmic side of the postsynaptic membrane, where it sits in direct opposition to the presynaptic terminal. The PSD functions both to cluster neurotransmitter receptors at the cell surface as well as organize the intracellular signaling molecules responsible for transducing extracellular signals to the postsynaptic cell. Much is known about the chemical composition of the PSD, but the structural arrangement of its molecular components is not well documented. Adding to the difficulty of understanding such a complex mass of protein machinery is the fact that its protein composition is known to change in response to synaptic activity, meaning that its structure is plastic and no two PSDs are identical. Here, immuno-gold labeling and electron tomography of PSDs isolated throughout development was used to track changes in both the structure and molecular composition of the PSD. State-of-the-art cryo-electron tomography was used to study the fine structure of the PSD during development, and provides an unprecedented glimpse into its molecular architecture in an un-fixed, unstained and hydrated state. Through this analysis, large structural and compositional changes are apparent and suggest a model by which the PSD is first assembled as a mesh-like lattice of proteins that function as support for the later recruitment of various PSD components. Spatial analysis of the recruitment of proteins into the PSD demonstrated that its assembly has an underlying order.

Social Salience and the Sociolinguistic Monitor: a Case Study of ING and TH-fronting in Britain

This article examines the role of social salience, or the relative ability of a linguistic variable to evoke social meaning, in structuring listeners’ perceptions of quantitative sociolinguistic distributions. Building on the foundational work of Labov et al. (2006, 2011) on the “sociolinguistic monitor” (a proposed cognitive mechanism responsible for sociolinguistic perception), we examine whether listeners’ evaluative judgments of speech change as a function of the type of variable presented. We consider two variables in British English, ING and TH-fronting, which we argue differ in their relative social salience. Replicating the design of Labov et al.’s studies, we test 149 British listeners’ reactions to different quantitative distributions of these variables. Our experiments elicit a very different pattern of perceptual responses than those reported previously. In particular, our results suggest that a variable’s social salience determines both whether and how it is perceptually evaluated. We argue that this finding is crucial for understanding how sociolinguistic information is cognitively processed.

Investigating the structure and form of condom decisional balance in an alternative school sample using confirmatory factor analysis

Teen pregnancy is a continuing problem, bringing with it a host of associated health and social risks. Alternative school students are especially at risk, but are historically under-represented in research. This is especially problematic in that instruments are needed to guide effective intervention development, but psychometrics for these instruments cannot be assumed when used in new populations. Decisional balance from the transtheoretical model offers a framework for understanding condom decision making, but has not been tested with alternative school students. Using responses from 640 subjects from Safer Choices 2 (a school-based HIV/STD/pregnancy prevention program implemented in 10 urban, southwestern alternative schools), a decisional balance scale for condom use was examined. A two-factor, mildly correlated model fit the data well. Tests of invariance examined scale functioning within gender and racial/ethnic groups. The underlying structure varied slightly based on subgroup, but on a practical level the impact on the use of scales was minimal. The structure and loadings were invariant across experimental condition. The pro scale was associated with a lower probability of having engaged in unprotected sexual behavior for sexually active subjects, and this association remained significant while controlling for demographic variables. The con scale did not show a significant association with engagement in unprotected sexual behaviors. Limitations and directions for future research were also discussed.^

Considering Social Factors and Potential Moderation Effects in Children’s Health Research

In light of dramatic changes in American family demography in recent decades, there is a growing recognition that family structure is one of a host of important social factors contributing to children’s health and well-being. The article by Augustine and Kimbro contributes to a growing body of research linking children’s family structure and health outcomes, focusing specifically on the association between family living arrangements and children’s risk of obesity. Their analyses are especially helpful in suggesting that family scholars should pay more attention to potential heterogeneity in relationships between family structure and children’s outcomes.

Family Structure and Obesity Among U.S. Children

Child obesity in the U.S. is a significant public health issue, particularly among children from disadvantaged backgrounds. Thus, the roles of parents’ human and financial capital and racial and ethnic background have become important topics of social science and public health research on child obesity. Less often discussed, however, is the role of family structure, which is an important predictor of child well-being and indicator of family socioeconomic status. The goal of this study, therefore, is to investigate how preschool aged children’s risk of obesity varies across a diverse set of family structures and whether these differences in obesity are moderated by family poverty status and the mothers’ education. Using a large nationally representative sample of children from the Early Childhood Longitudinal Study – Birth Cohort, we find that preschoolers raised by two biological cohabiting parents or a relative caregiver (generally the grandparent) have greater odds of being obese than children raised by married biological parents. Also, poor children in married biological parent households and non-poor children in married step parent households have greater obesity risks, while poor children in father only, unmarried step, and married step parent families actually have lower odds of obesity than children in non-poor intact households. The implications of these findings for policy and future research linking family structure to children’s weight status are discussed.

Structure and biosynthesis of a pyruvate -dependent enzyme---phosphatidylserine decarboxylase from {\it Escherichia coli\/}

Phosphatidylserine decarboxylase of E. coli, a cytoplasmic membrane protein, catalyzes the formation of phosphatidylethanolamine, the principal phospholipid of the organism. The activity of the enzyme is dependent on a covalently bound pyruvate (Satre and Kennedy (1978) J. Biol. Chem. 253, 479-483). This study shows that the enzyme consists of two nonidentical subunits, $\alpha$ (Mr = 7,332) and $\beta$ (Mr = 28,579), with the pyruvate prosthetic group in amide linkage to the amino-terminus of the $\alpha$ subunit. Partial protein sequence and DNA sequence analysis reveal that the two subunits are derived from a proenzyme ($\pi$ subunit, Mr = 35,893) through a post-translational event. During the conversion of the proenzyme to the $\alpha$ and $\beta$ subunits, the peptide bond between Gly253-Ser254 is cleaved, and Ser254 is converted to the pyruvate prosthetic group at the amino-terminus of the $\alpha$ subunit (Li and Dowhan (1988) J. Biol. Chem. 263, 11516-11522).^ The proenzyme cannot be detected in cells carrying either single or multiple copies of the gene (psd), but can be observed in a T7 RNA polymerase/promoter and transcription-translation system. The cleavage of the wild-type proenzyme occurs rapidly with a half-time on the order of 2 min. Changing of the Ser254 to cysteine (S254C) or threonine (S254T) slows the cleavage rate dramatically and results in mutants with a half-time for processing of around 2-4 h. Change of the Ser254 to alanine (S254A) blocks the cleavage of the proenzyme. The reduced processing rate with the mutations of the proenzyme is consistent with less of the functional enzyme being made. Mutants S254C and S254T produce $\sim$15% and $\sim$1%, respectively, of the activity of the wild-type allele, but can still complement a temperature-sensitive mutant of the psd locus. Neither detectable activity nor complementation is observed by mutant S254A. These results are consistent with the hydroxyl-group of the Ser254 playing a critical role in the cleavage of the peptide bond Gly253-Ser254 of the pro-phosphatidylserine decarboxylase, and support the mechanism proposed by Snell and co-workers (Recsei and Snell (1984) Annu. Rev. Biochem. 53, 357-387) for the formation of the prosthetic group of pyruvate-dependent decarboxylases. ^

The effects of DNA cytosine methylation on H -ras promoter structure and function

The effect of DNA cytosine methylation on H-ras promoter activity was assessed using a transient expression system employing the plasmid H-rasCAT (NaeI H-ras promoter linked to the chloramphenicol acetyltransferase (CAT) gene). This 551 bp promoter is 80% GC rich, enriched with 168 CpG dinucleotides, and contains six functional GC box elements which represent major DNA methylation target sites. Prokaryotic methyltransferases HhaI (CGm$\sp5$CG) and HpaII (Cm$\sp5$CGG) alone or in combination with a human placental methyltransferase (HP MTase) were used to introduce methyl groups at different CpG sites within the promoter. To test for functional promoter activity, the methylated plasmids were introduced into CV-1 cells and CAT activity assessed 48 h post-transfection. Methylation at specific HhaI and HpaII sites reduced CAT expression by 70%, whereas more extensive methylation at generalized CpG sites with HP MTase inactivated the promoter $>$95%. The inhibition of H-ras promoter activity was not attributable to methylation-induced differences in DNA uptake or stability in the cell, topological form of the plasmid, or methylation effects in nonpromoter regions. We also observed that DNA cytosine methylation of a 360 bp promoter fragment by HP MTase induced a local change in DNA conformation. Using three independent methodologies (nitrocellulose filter binding assays, gel mobility shifts, and Southwestern blots), we determined that this change in promoter conformation affected the interaction of nuclear proteins with cis-regulatory sequences residing in the promoter region. The results provide evidence to suggest that DNA methylation may regulate gene expression by inducing changes in local promoter conformation which in turn alters the interactions between DNA and protein factors required for transcription. The results provide supportive evidence for the hypothesis of Cedar and Riggs, who postulated that DNA methylation may regulate gene expression by altering the binding affinities of proteins for DNA. ^
