A Preliminary Qualitative Investigation of Voice Hearing and Its Association with Dissociation in Chronic PTSD

Following on from a quantitative study, this research used a qualitative methodology to investigate the lived experience of 3 men with chronic posttraumatic stress disorder associated with the conflict in Northern Ireland who reported auditory hallucinations. Data analysis used the Framework method. Results showed that beliefs about voices, dissociation of identity and body, and interpersonal impact were central superordinate themes associated with auditory hallucinations in posttraumatic stress disorder. Central subordinate themes included feeling a lack of controllability over voices, experiencing them as ego-dystonic, and feeling an increased sense of isolation and shame because of their presence. Results provide an in-depth analysis of participants' lived experiences and enhance understanding of previous quantitative findings.

Lead in rice: Analysis of baseline lead levels in market and field collected rice grains

In a large scale survey of rice grains from markets (13 countries) and fields (6 countries), a total of 1578 rice grain samples were analysed for lead. From the market collected samples, only 0.6% of the samples exceeded the Chinese and EU limit of 0.2 μg g− 1 lead in rice (when excluding samples collected from known contaminated/mine impacted regions). When evaluating the rice grain samples against the Food and Drug Administration's (FDA) provisional total tolerable intake (PTTI) values for children and pregnant women, it was found that only people consuming large quantities of rice were at risk of exceeding the PTTI from rice alone. Furthermore, 6 field experiments were conducted to evaluate the proportion of the variation in lead concentration in rice grains due to genetics. A total of 4 of the 6 field experiments had significant differences between genotypes, but when the genotypes common across all six field sites were assessed, only 4% of the variation was explained by genotype, with 9.5% and 11% of the variation explained by the environment and genotype by environment interaction respectively. Further work is needed to identify the sources of lead contamination in rice, with detailed information obtained on the locations and environments where the rice is sampled, so that specific risk assessments can be performed.

Father Identity, Involvement and Work–Family Balance: An In-depth Interview Study

Work and family roles have changed considerably in the past number of decades. Fathers are now expected to fulfil the role of 'new father' that involves actively caring and sharing in child rearing and, at the same time, maintain commitment to their occupational role. As a consequence, men are subject to the same pressure that women were when they initially entered the workplace decades ago and indeed still are today. This study aims to explore the meanings fathers attach to their life roles, how these meanings influence behaviour within these roles and how they negotiate the demands of these roles. In-depth interviews were carried out with 15 fathers, and the results were analysed adhering to the principles of grounded theory. The findings show the variability among fathers in both their commitment to fathering and the meanings they attach to that role. A significant tension between new fatherhood ideals and actual fathering practices is also apparent. These findings are discussed drawing upon traditional definitions of masculinity and wider occupational and cultural influences.

Multi-centre research in Australia:analysis of a recent National Health and Medical Research Council-funded project

BACKGROUND AND OBJECTIVE: Human research ethics committees provide essential review of research projects to ensure the ethical conduct of human research. Several recent reports have highlighted a complex process for successful application for human research ethics committee approval, particularly for multi-centre studies. Limited resources are available for the execution of human clinical research in Australia and around the world.

METHODS: This report overviews the process of ethics approval for a National Health and Medical Research Council-funded multi-centre study in Australia, focussing on the time and resource implications of such applications in 2007 and 2008.

RESULTS: Applications were submitted to 16 hospital and two university human research ethics committees. The total time to gain final approval from each committee ranged between 13 and 77 days (median = 46 days); the entire process took 16 months to complete and the research officer's time was estimated to cost $A34 143.

CONCLUSIONS: Obstacles to timely human research ethics committee approval are reviewed, including recent, planned and potential initiatives that could improve the ethics approval of multi-centre research.

Development of a Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) Cell for the In Situ Analysis of Co-Electrolysis in a Solid Oxide Cell

Co-electrolysis of carbon dioxide and steam has been shown to be an efficient way to produce syngas, however further optimisation requires detailed understanding of the complex reactions, transport processes and degradation mechanisms occurring in the solid oxide cell (SOC) during operation. Whilst electrochemical measurements are currently conducted in situ, many analytical techniques can only be used ex situ and may even be destructive to the cell (e.g. SEM imaging of microstructure). In order to fully understand and characterise co-electrolysis, in situ monitoring of the reactants, products and SOC is necessary. Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) is ideal for in situ monitoring of co-electrolysis as both gaseous and adsorbed CO and CO2 species can be detected, however it has previously not been used for this purpose. The challenges of designing an experimental rig which allows optical access alongside electrochemical measurements at high temperature and operates in a dual atmosphere are discussed. The rig developed has thus far been used for symmetric cell testing at temperatures from 450[degree]C to 600[degree]C. Under a CO atmosphere, significant changes in spectra were observed even over a simple Au|10Sc1CeSZ|Au SOC. The changes relate to a combination of CO oxidation, the water gas shift reaction and carbonate formation and decomposition processes, with the dominant process being both potential and temperature dependent.

In silico analysis and DHPLC screening strategy identifies novel apoptotic gene targets of aberrant promoter hypermethylation in prostate cancer

BACKGROUND: Aberrant DNA methylation has been implicated as a key survival mechanism in cancer, whereby promoter hypermethylation silences genes essential for many cellular processes including apoptosis. Limited data is available on the methylation profile of apoptotic genes in prostate cancer (CaP). The aim of this study was to profile methylation of apoptotic-related genes in CaP using denaturing high performance liquid chromatography (DHPLC).

METHODS: Based on an in silico selection process, 13 genes were screened for methylation in CaP cell lines using DHPLC. Quantitative methylation specific PCR was employed to determine methylation levels in prostate tissue specimens (n = 135), representing tumor, histologically benign prostate, high-grade prostatic intraepithelial neoplasia and benign prostatic hyperplasia. Gene expression was measured by QRT-PCR in cell lines and tissue specimens.

RESULTS: The promoters of BIK, BNIP3, cFLIP, TMS1, DCR1, DCR2, and CDKN2A appeared fully or partially methylated in a number of malignant cell lines. This is the first report of aberrant methylation of BIK, BNIP3, and cFLIP in CaP. Quantitative methylation analysis in prostate tissues identified 5 genes (BNIP3, CDKN2A, DCR1, DCR2 and TMS1) which were frequently methylated in tumors but were unmethylated in 100% of benign tissues. Furthermore, 69% of tumors were methylated in at least one of the five-gene panel. In the case of all genes, except BNIP3, promoter hypermethylation was associated with concurrent downregulation of gene expression.

CONCLUSION: Future examination of this "CaP apoptotic methylation signature" in a larger cohort of patients is justified to further evaluate its value as a diagnostic and prognostic marker.

Gender and Cosmopolitanism in Europe: A Feminist Perspective

Gender and Cosmopolitanism in Europe combines a feminist critique of contemporary and prominent approaches to cosmopolitanism with an in-depth analysis of historical cosmopolitanism and the manner in which gendered symbolic boundaries of national political communities in two European countries are drawn. Exploring the work of prominent scholars of new cosmopolitanism in Britain and Germany, including Held, Habermas, Beck and Bhabha, it delivers a timely intervention into current debates on globalisation, Europeanisation and social processes of transformation in and beyond specific national societies.

A rigorous examination of the emancipatory potential of current debates surrounding cosmopolitanism in Europe, this book will be of interest to sociologist and political scientists working on questions of identity, inclusion, citizenship, globalisation, cosmopolitanism and gender.
