Rethinking empowerment: a postmodern reappraisal for emancipatory practice

This article is concerned with the implications of the postmodern challenge to critical theory for the practice of empowerment. How do we conceptualize empowerment from a postmodern perspective? It is argued that the modernist concept of power upon which empowerment rests, can have unintended disempowering effects. By conceptualizing power as a commodity, identities are forced into a powerful–powerless dualism which does not always do justice to diverse experiences. Thus we can sometimes contribute to dominance in spite of our liberatory intentions. It is argued that social workers need to become more aware of the self-disciplining and self-regulatory processes involved in professional work to address the social relations of power embedded in professional practices. Foucault's analysis of how marginalized knowledges are affected by dominant cultural practices suggests a redefining of empowerment as the insurrection of subjugated knowledge. The implications of this redefinition for practice is illustrated by reference to work with indigenous people in Australia.

Creatine transporters: a reappraisal

Creatine (Cr) plays a key role in cellular energy metabolism and is found at high concentrations in metabolically active cells such as skeletal muscle and neurons. These, and a variety of other cells, take up Cr from the extra cellular fluid by a high affinity Na⁺/Cl^--dependent creatine transporter (CrT). Mutations in the crt gene, found in several patients, lead to severe retardation of speech and mental development, accompanied by the absence of Cr in the brain.
In order to characterize CrT protein(s) on a biochemical level, antibodies were raised against synthetic peptides derived from the N- and C-terminal cDNA sequences of the putative CrT-1 protein. In total homogenates of various tissues, both antibodies, directed against these different epitopes, recognize the same two major polypetides on Western blots with apparent Mr of 70 and 55 kDa. The C-terminal CrT antibody (α-CrTCOOH) immunologically reacts with proteins located at the inner membrane of mitochondria as determined by immuno-electron microscopy, as well as by subfractionation of mitochondria. Cr-uptake experiments with isolated mitochondria showed these organelles were able to transport Cr via a sulfhydryl-reagent-sensitive transporter that could be blocked by anti-CrT antibodies when the outer mitochondrial membrane was permeabilized. We concluded that mitochondria are able to specifically take-up Cr from the cytosol, via a low-affinity CrT, and that the above polypeptides would likely represent mitochondrial CrT(s). However, by mass spectrometry techniques, the immunologically reactive proteins, detected by our anti-CrT antibodies, were identified as E2 components of the agr-keto acid dehydrogenase multi enzyme complexes, namely pyruvate dehydrogenase (PDH), branched chain keto acid dehydrogenase (BC-KADH) and α-ketoglutarate dehydrogenase (α-KGDH). The E2 components of PDH are membrane associated, whilst it would be expected that a mitochondrial CrT would be a transmembrane protein. Results of phase partitioning by Triton X-114, as well as washing of mitochondrial membranes at basic pH, support that these immunologically cross-reactive proteins are, as expected for E2 components, membrane associated rather than transmembrane. On the other hand, the fact that mitochondrial Cr uptake into intact mitoplast could be blocked by our α-CrTCOOH antibodies, indicate that our antisera contain antibodies reactive to proteins involved in mitochondrial transport of Cr. The presence of specific antibodies against CrT is also supported by results from plasma membrane vesicles isolated from human and rat skeletal muscle, where both 55 and 70 kDa polypeptides disappeared and a single polypeptide with an apparent electrophoretic mobility of ~ 60 kDa was enriched This latter is most likely representing the genuine plasma membrane CrT.
Due to the fact that all anti-CrT antibodies that were independently prepared by several laboratories seem to cross-react with non-CrT polypeptides, specifically with E2 components of mitochondrial dehydrogenases, further research is required to characterise on a biochemical/biophysical level the CrT polypeptides, e.g. to determine whether the ~ 60 kDa polypeptide is indeed a bona-fide CrT and to identify the mitochondrial transporter that is able to facilitate Cr-uptake into these organelles. Therefore, the anti-CrT antibodies available so far should only be used with these precautions in mind. This holds especially true for quantitation of CrT polypeptides by Western blots, e.g. when trying to answer whether CrT's are up- or down-regulated by certain experimental interventions or under pathological conditions.
In conclusion, we still hold to the scheme that besides the high-affinity and high-efficiency plasmalemma CrT there exists an additional low affinity high Km Cr uptake mechanism in mitochondria. However, the exact biochemical nature of this mitochondrial creatine transport, still remains elusive. Finally, similar to the creatine kinase (CK) isoenzymes, which are specifically located at different cellular compartments, also the substrates of CK are compartmentalized in cytosolic and mitochondrial pools. This is in line with ¹⁴C-Cr-isotope tracer studies and a number of [³¹P]-NMR magnetization transfer studies, as well as with recent [¹H]-NMR spectroscopy data.

An early painter's persona as metaphor

This article analyses the marketing of an early Australian entrepreneurial female painter as metaphor in the exploration of the brand concept. It does so through the extension of her persona to her art, through examination of her diaries, letters and public documents. The use of the metaphor as a means of promulgating the 'brand as person' is discussed. Thus, the buyer of art chooses a painting with confidence because of the personality projected by the creator of the art work, in the same way as a successful brand of another product might be purchased. This article places the analysis within the context of social change of the time, giving some indication of the market and competitor positions and her motivation for differentiating herself from others. It highlights the conflict that the painter's brand caused to the artist's competitors at the time and how that affected her long-term reputation. The artist's idiosyncratic approach to painting and her vigorous self-promotion as an artist sought a reappraisal of the genre of lowly flower painting in the late nineteenth century.

The impact of the financial costs of multiple sclerosis on quality of life

This study examined the financial costs of multiple sclerosis (MS) and the impact of financial strain on the subjective quality of life of people with MS and their families. Due to the lack of research in this area, a qualitative research design was employed. Interviews were conducted with 16 health professionals, 26 people with MS, and 11 family members of people who had MS. Adjusting to actual or threatened loss of income caused financial stress. These financial struggles led to a lower quality of life among respondents. Problem solving, coping, and positive reappraisal helped people to adjust to financial changes. Professionals focused on increased funding for services, whereas people with MS focused on improved income support. These findings highlight the need for professionals to consider the financial strain associated with this disease and the impact of this strain on the quality of life of individuals with MS and their families.

Self-related quality of life scales for people with an intellectual disability : a reply to Ager & Hutton

An earlier publication by the present author concerning quality of life (QoL) measurement has been critiqued by A. Ager and C. Hatton. The present paper addresses the issues raised. It commences with a reappraisal of the Life Experiences Checklist and confirms the present author's view that this instrument is not adequate to measure QoL in accordance with contemporary understanding of the construct. It is argued that QoL scales should include both objective and subjective measurements across a minimum set of domains adequate to embrace the whole life experience. Finally, the usefulness of QoL measurement for people with intellectual disability is debated.

The modern Medea : Euripides, anti-imperialism and infanticide

Euripides' Medea has been reinvented several times in the twentieth century. This paper uncovers the impetus that informs the lineage of Medeas that are overt in their politicisation of the problems of colonialism and/or institutionalised gender dissymmetry: the Medeas of Pier Paolo Pasolini, Heiner Mller, Brendan Kennelly, Liz Lochhead, Christa Wolf, Diana Wakoski, Tony Harrison - and more recently Wesley Enoch. What, however, lends the Euripidean narrative to such politicisations? To answer this question, the paper looks back to Euripides' play, offering a reappraisal of its representation of infanticide. The paper argues that while this motif is routinely dismissed in the scholarship as a demonising representation of the cultural and sexual Other, the infanticide motif is also the key to understanding Medea's radicality and politicisation of rights-bearing subjectivity in its ancient and modern incarnations.

Human rights in Asia: A reassessment of the Asian values debate

"This book offers a critical reassessment of the "Asian values" debate, which dominated the human rights discourse in the late 1990s, and a reappraisal of the human rights situation in Asia since then. In this book Asian and non-Asian scholars contextualize the "Asian values" debate and examine in what ways the issues raised then continue to trouble Asian societies. Human rights are seen both in the context of political developments in individual Asian countries as well as in relation to global issues such as the Global War on Terror. The book challenges the reader to critically examine human rights rhetoric and practice both in Asia and globally."--BOOK JACKET.

Developing english skills through reflective portfolios in Hong Kong universities

This research concerns the use of portfolios by teachers of English (L2) to assist non-native speakers in Hong Kong universities to complete their studies in English. Portfolios as an English learning tool have yet to win converts from the ranks of language teachers in Hong Kong chiefly because of concerns about reliability and fairness. Two recent initiatives in Hong Kong have, however, prompted a reappraisal of the place of portfolios in English language learning. They include the use of learning portfolios in secondary school and ePortfolios by university students for learning and employment purposes.

As an English (L2) teacher of many years, I initiated my research to investigate the experiences of seven university students in Hong Kong in using reflective portfolios for English learning. Three research questions framed my research: 1) in what ways can reflective portfolios impact on L2 learning strategies? 2) what are the effects of reflective portfolios on progress in L2 acquisition as perceived by students? 3) what are the perceptions of university students towards reflective portfolios as a method of L2 learning?

To gain a holistic understanding of the complex phenomena under scrutiny, a case study methodology and grounded theory were utilised, the former to organise and generate qualitative data, and the latter to analyse data from three sources provided by the seven participating students: semi-structured interviews, portfolio artefacts, and weekly learning diaries.

There were two levels of data analysis. For the first level, analysis focused on coded data from portfolio artefacts, diary entries and interview transcripts as reported by students. The second level involved analysis from the Confucian and sociocultural perspectives. I pursued interpretation and continuous refinement of the data by using techniques drawn from grounded theory. The findings revealed that students generally employed a wide spread of L2 learning strategies in the cognitive, meta-cognitive, and socio-affective domain, reported increased awareness of effective language strategies, and considered portfolios a means of supporting time management and record-keeping, and a site for extended writing practice through reflection.

The findings suggest that students display a cyclical, context-specific shift in learning conception from quantitative to qualitative. Connected to this is students’ apparent ability to formulate strategic responses to externally imposed demands. It is found that such responses are culturally triggered, underpinned by Confucian beliefs. Although the Confucian tradition emphasises respect for established authority, the findings point to students’ creative re-configuration of mental schemata to engender change in role enactment and power relations, with the portfolio as a mediating tool of their experiences.

Based on the findings, I argue that my research has addressed the three research questions and contributed to two crucial aspects of L2 learning. The first pertains to the need for a balanced view of individual effort and social context in second language acquisition, corroborating the significant link between context and learner engagement. Another contribution centres on an enhanced understanding of the relationship between portfolios, reflection and L2, where students’ diaries in English and portfolio artefacts enable them to engage in critical reflection and to identify strategies for L2 improvement.

A case-control study of emotion regulation and school refusal in children and adolescents

The current study aimed to investigate emotion regulation (ER) strategy use in a sample of 21 clinic-referred children and adolescents (10-14 years old) presenting with school refusal, all of whom were diagnosed with at least one anxiety disorder. Being the first known study to examine ER and school refusal, hypotheses were guided by previous research on anxiety. It was hypothesized that the school refusal sample would report less healthy ER strategy use compared to an age- and sex-matched nonclinical sample (n = 21). As expected, the school refusal sample reported less use of cognitive reappraisal and greater use of expressive suppression to regulate their emotions than did the nonclinical sample. Although preliminary, the findings provide important information regarding the emotional functioning of children and adolescents presenting with school refusal. Future directions for research and implications for improved prevention and intervention programs are discussed.

Pathways to social anxiety: the role of reinforcement sensitivities and emotion regulation

Past research has demonstrated a strong relationship between threat sensitivity and social anxiety; however, the relationship between reward sensitivity and social anxiety is less clear. Further, the role that emotion regulation (ER) may play in the expression of social anxiety disorder (SAD) is rarely considered. The current study tested whether two emotion regulation strategies (emotional suppression and cognitive reappraisal) mediated associations between threat sensitivity and reward sensitivity and social anxiety in a community sample (402 adults, 78% female; Mage=32.49, S.D.age=11.53). Path analyses indicated that low reappraisal mediated the relationship between high threat sensitivity and high social anxiety; and both low reappraisal and high suppression mediated the relationship between low reward sensitivity and high social anxiety. These results highlight the potential role that emotion regulation plays in the relationship between trait motivation and social anxiety.
