The executive committee of the Greek Professional Association of Social Work in an age of austerity: examining its response

This paper explores the response by the Greek Association of Social Workers (SKLE) to Greece's current economic crisis. Socioeconomic conditions in Greece have deteriorated rapidly since the imposition of a Structural Adjustment Programme as a condition of the loan Troika provided to Greece to address its class-based public debt crisis. Interviews were conducted with SKLE Executive Committee members to examine SKLE's response in the context of newly raised inequalities. Research results show that SKLE recognised the negative consequences to both service users and its members. However, SKLE continues to reformulate its strategy mostly as a social partner. SKLE's previous strategy entailed amongst other things the analysis of policy proposals and participation in welfare related government committees. This strategy is no longer relevant because decision-making powers have been transferred to transnational bodies. This paper elaborates on these findings and discusses the barriers that prohibit SKLE from differentiation of its strategy. Although the research is country specific, it has implications for the broader global debate because professional associations must reformulate their strategies for better serving of both their constituents and the collective good based on the social justice mandate of the profession.

The Risk Implications of Globalisation: An Exploratory Analysis of 105 Major Industrial Incidents (1971–2010)

This paper revisits work on the socio-political amplification of risk, which predicts that those living in developing countries are exposed to greater risk than residents of developed nations. This prediction contrasts with the neoliberal expectation that market driven improvements in working conditions within industrialising/developing nations will lead to global convergence of hazard exposure levels. It also contradicts the assumption of risk society theorists that there will be an ubiquitous increase in risk exposure across the globe, which will primarily affect technically more advanced countries. Reviewing qualitative evidence on the impact of structural adjustment reforms in industrialising countries, the export of waste and hazardous waste recycling to these countries and new patterns of domestic industrialisation, the paper suggests that workers in industrialising countries continue to face far greater levels of hazard exposure than those of developed countries. This view is confirmed when a data set including 105 major multi-fatality industrial disasters from 1971 to 2000 is examined. The paper concludes that there is empirical support for the predictions of socio-political amplification of risk theory, which finds clear expression in the data in a consistent pattern of significantly greater fatality rates per industrial incident in industrialising/developing countries.

Promoter region of the Escherichia coli O7-specific lipopolysaccharide gene cluster:structural and functional characterization of an upstream untranslated mRNA sequence

We report the identification of the promoter region of the Escherichia coli O7-specific lipopolysaccharide (LPS) gene cluster (wbEcO7). Typical -10 and -35 sequences were found to be located in the intervening region between galF and rlmB, the first gene of the wbEcO7 cluster. Data from RNase protection experiments revealed the existence of an untranslated leader mRNA segment of 173 bp, including the JUMPStart and two ops sequences. We characterized the structure of this leader mRNA by using the program Mfold and a combination of nested and internal deletions transcriptionally fused to a promoterless lac operon. Our results indicated that the leader mRNA may fold into a series of complex stem-loop structures, one of which includes the JUMPStart element. We have also found that one of the ops sequences resides on the predicted stem and the other resides on the loop region, and we confirmed that these sequences are essential for the RfaH-mediated regulation of the O polysaccharide cluster. A very similar stem-loop structure could be predicted in the promoter region of the LPS core operon encoding the waaQGPSBIJYZK genes. We observed another predicted stem-loop, located immediately downstream from the wbEcO7 transcription initiation site, which appeared to be involved in premature termination of transcription. This putative stem-loop is common to many other O polysaccharide gene clusters but is not present in core oligosaccharide genes. wbEcO7-lac transcriptional fusions in single copy numbers were also used to determine the effects of various environmental cues in the transcriptional regulation of O polysaccharide synthesis. No effects were detected with temperature, osmolarity, Mg2+ concentration, and drugs inducing changes in DNA supercoiling. We therefore conclude that the wbEcO7 promoter activity may be constitutive and that regulation takes place at the level of elongation of the mRNA in a RfaH-mediated manner.

Cross-Cultural Intelligence (CQ): its impact on British Expatriates Adjustment in International Construction Projects

Purpose: The purpose of this paper is to investigate the relationship between the facets of cultural intelligence (CQ) (cognitive, meta-cognitive, motivational and behavioural) and the dimensions of cross-cultural adjustment (interaction, general and work adjustment).

Design/methodology/approach: Interviews and questionnaire survey were carried out with British expatriates from the architectural, engineering and construction sector. A total of 191 respondents, with experience from 29 different countries, actively participated in this research. Structural equation model was subsequently developed to investigate the relationship between elements of CQ and cross-cultural adjustment.

Findings: Results of structural equation modelling revealed that collectively all the four aspects of CQ have significant influence on general, interaction and work adjustment, particularly motivational and cognitive CQ. Cognitive CQ which empowers the expatriates with in-depth knowledge about different cultures was a significant predictor of interaction and work adjustment, whereas, motivational CQ is a significant predictor for general and work adjustment. However, no support was gathered for meta-cognitive and behavioural aspects of CQ.

Practical implications: Globally, construction companies and projects are entering an era of increased internationalisation which has prompted the migration/promotion of British construction professionals to different parts of the world for their specialised capabilities and skills. Thus, it is of utmost importance that these professionals adjust to their new world of varied culture and still be productive in their work.

Originality/value: An understanding of these essential factors can actually help British construction organisations to select and mentor individuals and to provide necessary training for successful international assignments.

Evaluating program integration and the rise in collaboration:Case study of a palliative care network

Introduction: There is increasing global interest in using regional palliative care networks (PCNs) to integrate care and create systems that are more costeffective and responsive. We examined a PCN that used a community development approach to build capacity for palliative care in each distinct community in a region of southern Ontario, Canada, with the goal of achieving a competent integrated system. Methods: Using a case study methodology, we examined a PCN at the structural level through a document review, a survey of 20 organizational administrators, and an interview with the network director. Results: The PCN identified 14 distinct communities at different stages of development within the region. Despite the lack of some key features that would facilitate efficient palliative care delivery across these communities, administrators largely viewed the network partnership as beneficial and collaborative. Conclusion: The PCN has attempted to recognize specific needs in each local area. Change Is gradual but participatory. There remain structural issues that may negatively affect the functioning of the PCN.

A Randomized Controlled Trial of Interventions to Promote Adjustment in Children With Congenital Heart Disease Entering School and Their Families

Objective: To report on a randomized controlled trial of psychological interventions to promote adjustment in children with congenital heart disease and their families.
Method: Following baseline assessment, 90 children (aged 4–5 years) and their families were randomly assigned to an Intervention or Control group before entering school. 68 (76%) were retained at 10-month follow-up.
Results: Gains were observed on measures of maternal mental health and family functioning. Although no differences were found on measures of child behavior at home or school, children in the intervention group were perceived as “sick” less often by their mother and missed fewer days from school. A regression model, using baseline measures as predictors, highlighted the importance of maternal mental health, worry and child neurodevelopmental functioning for child behavioral outcomes almost a year later.
Conclusions: The intervention promoted clinically significant gains for the child and family. The program is of generalizable significance.

Exploiting dynamic timing margins in microprocessors for frequency-over-scaling with instruction-based clock adjustment

Static timing analysis provides the basis for setting the clock period of a microprocessor core, based on its worst-case critical path. However, depending on the design, this critical path is not always excited and therefore dynamic timing margins exist that can theoretically be exploited for the benefit of better speed or lower power consumption (through voltage scaling). This paper introduces predictive instruction-based dynamic clock adjustment as a technique to trim dynamic timing margins in pipelined microprocessors. To this end, we exploit the different timing requirements for individual instructions during the dynamically varying program execution flow without the need for complex circuit-level measures to detect and correct timing violations. We provide a design flow to extract the dynamic timing information for the design using post-layout dynamic timing analysis and we integrate the results into a custom cycle-accurate simulator. This simulator allows annotation of individual instructions with their impact on timing (in each pipeline stage) and rapidly derives the overall code execution time for complex benchmarks. The design methodology is illustrated at the microarchitecture level, demonstrating the performance and power gains possible on a 6-stage OpenRISC in-order general purpose processor core in a 28nm CMOS technology. We show that employing instruction-dependent dynamic clock adjustment leads on average to an increase in operating speed by 38% or to a reduction in power consumption by 24%, compared to traditional synchronous clocking, which at all times has to respect the worst-case timing identified through static timing analysis.

Contribution of genetic and environmental effects on lens thickness: the Guangzhou Twin Eye study.

PURPOSE:

This study investigated the heritability of lens thickness (LT) and relative lens thickness (LT/axial length, rLT) measured by Lenstar among Chinese children and adolescents in the Guangzhou Twin Eye study.

METHODS:

Twins aged 8 to 22 years were enrolled from the Guangzhou Twin Registry. A series of LT and axial length (AL) measurements using the Lenstar were taken for each twin. Zygosity was confirmed by genotyping in all same-sex twin pairs. Heritability was assessed by structural variance component genetic modeling, after adjustment for age and sex with the Mx program.

RESULTS:

Seven hundred sixty-eight twin pairs (482 monozygotic [MZ] and 286 dizygotic [DZ] twins) were available for data analysis. The mean (standard deviation) LT and rLT were 3.45 (0.18) mm and 0.142 (0.01), respectively. The intraclass correlation coefficients (ICCs) for LT were 0.90 for the MZ and 0.39 for the DZ twins; and those for rLT were 0.90 for the MZ and 0.40 for the DZ twins, respectively. The best-fitting model yielded 89.5% (95% CI: 87.8%-91.0%) of additive genetic effects and 10.5% (95% CI: 9.0%-12.2%) of unique environmental effects for LT, and 89.3% (95% CI: 89.2%-89.3%) of additive genetic effects and 10.7% (95% CI: 10.7%-11.4%) of unique environmental effects for rLT.

CONCLUSIONS:

This study confirms that the LT in young healthy subjects may be mainly affected by additive genetic factors. High heritability remains even when the data are corrected for the influence of AL with the use of rLT.
