Factors affecting vulnerability to depression among gay men and lesbian women

The present study explored factors affecting vulnerability to depression among gay men and lesbian women in metropolitan Gauteng, South Africa. Risk factors consistently cited in the literature on depression among gay men and lesbian women, namely self-esteem, social integration, hate speech, physical victimisation, fear of victimisation and alcohol and drug abuse, were examined to determine their ability to predict vulnerability to depression. Data was collected from 385 participants who self-identified as lesbian or gay, using a purposive quota sampling technique to ensure representation across age, gender, race and socio-economic status lines. Participants were selected through gay and lesbian organisations, support groups, counselling centres, the gay and lesbian Pride Parade, an online questionnaire, and via snowballing techniques. Multiple regression analysis indicated that self-esteem and hate speech were the only significant predictors of vulnerability to depression. The regression model accounted for 21.7% of the variance in vulnerability to depression scores.PsychologyM. Sc. (Psychology

Performance Assessment of Local Mobility Policy-Making Administrations Using the Principles of Total Quality Management in Flanders, Belgium: Expounding the Decision-Making Processes

peer reviewedThis article describes a quality assessment of the processes underlying municipal mobility policy-making in Flanders, Belgium. 25 criteria and 176 aspects were queried during 25 interview sessions. Results were aggregated at the level of 7 quality domains of action and suggest that Flemish municipal mobility policy-making is generally fairly frail and of an ad-hoc nature. Four factors are found to be determining for this finding: default of political continuity, internal conflicts between stakeholders, lacking internal expertise, and deficient financial resources. Inter-stakeholder collaboration, residents’ participation, and policy-integration with higher-level programs are the strengths of current mobility policy practices in Flanders

The effect of wind turbines alongside motorways on drivers’ behaviour

This paper presents the results of a first study aimed at investigating whether the presence of wind turbines in close proximity to motorways leads to behavioural adaptations among passing drivers. Empirical data from loop detectors and temporary video cameras were analysed in a study employing a before-and-after design at a site near Rotterdam, The Netherlands. Analyses of driving speed and standard deviation of speed (corrected for trend effects through the use of control sites) were performed as well as analyses of the lateral position and standard deviation of the lateral position and an observation of serious traffic conflicts. The results showed that constructing wind turbines alongside a motorway led to some clearly observable effects on drivers’ behaviour. The analyses of the speed data showed that the mean speed was lowered by 2.24km/h (corrected for trend effects) after the construction of the wind turbines while the standard deviation of the speed significantly increased. After the construction of the wind turbines, drivers took a lateral position somewhat more to the left-hand side in their driving lane. There was an indication close to the 0.05 significance level (p=0.057) that the standard deviation of the lateral position slightly increased when the rotor blades were in transversal position. In the before period as well as in the after period, no serious traffic conflicts were registered. The increase in standard deviation of speed and in lateral position are two factors that intrinsically can have an unfavourable effect on road safety. However, the observed order of magnitude of the change was shown to be quite limited. Earlier research suggests that negative effects on road safety are only expected for changes substantially greater than the ones that were observed in this study. On the other hand, there was a significant reduction in driving speed, which might have a favourable effect on the expected number and severity of crashes, although it could also be a compensatory mechanism that indirectly indicates a reduced driving performance. From these findings, it can be concluded that, based on the observed variables, no substantial negative effects for road safety were found in the present study. The authors recommend continuous monitoring and further research on the topic

Transferring the Integrated Pollution Prevention and Control (IPPC) Approach and Best Available Techniques (BAT) Concepts to Egypt, Tunisia and Morocco

The principles introduced by the Directive Concerning Integrated Pollution Prevention and Control (IPPC) (currently known as the Industrial Emissions Directive (2010/75/EU)) are innovative and have raised interests in the framework of the literature debate on environmental regulation. Many articles describe and analyze the application of the Directive in European countries, but only a few articles focus on how the interest for the Directive's principles, including the integrated approach, have reached countries outside the European Union. This paper aims to contribute to this topic, describing the experience of the authors in carrying out an EU-funded project on transferring the IPPC approach and Best Available Techniques (BAT) concepts to three Arab countries, i.e. , Egypt, Morocco and Tunisia. The paper presents the experience referring to two sectors falling within the scope of the IPPC Directive: the textile and dairy sector. The objectives, methodologies, activities and experiences are described and can be used and valorized to integrate the IPPC approach and BAT concepts in the current environmental legislation of the three countries

Characterization and Limitations of Diffusion Tensor Imaging Metrics in the Cervical Spinal Cord in Neurologically Intact Subjects

Purpose To characterize diffusion tensor imaging (DTI) metrics across all levels of the cervical spinal cord (CSC) and to study the impact of age and signal quality on these metrics. Materials and Methods DTI metrics were calculated for gray matter (GM) and white matter (WM) funiculi throughout the CSC (C1–T1) in 25 healthy subjects (22-85 years old). Signal-to-noise ratios (SNRs) and mean DTI metrics were measured for the upper (C1-3), middle (C4-6) and lower (C7-T1) cervical segments. Age-related changes in DTI metrics were analyzed for the individual segment groups. Results Fractional anisotropy (FA), mean diffusivity (MD) and transverse apparent diffusion coefficient (tADC) showed significant differences between GM and WM funiculi. Significant age-related changes were observed in FA in upper and middle CSC segments but not in the lower CSC. The median SNR was significantly lower in the middle and lower segment groups as compared to the upper levels, contributing to poor spatial resolution in these regions. Conclusion This study provides DTI data for GM and WM funiculi throughout the CSC. While DTI metrics may be used to define cord pathology, variations in metrics due to age and signal quality need to be accounted for before making definitive conclusions. J. Magn. Reson
