Augmenting/reducing of the evoked potential has been shown to be related to sensation seeking (SS) and specific clinical disorders. Buchsbaum demonstrated that patients with bipolar affective disorders (BAD) tend to be augmenters, as is the case with sensation seekers, and patients with unipolar affective disorders (UPD) tend to be reducers. In addition, he reported that prophylactic medication reduced the tendency to augment in bipolar patients. However, evidence for these relations is restricted to a few studies. This study explores whether Buchsbaum’s initial findings can be found in a naturalistic clinical setting. Acoustic evoked potentials were recorded for six levels of intensity (59, 71, 79, 88, 92, 96 dB SPL) from 24 healthy adults, 21 unipolar depressed patients, and 21 patients with BAD. Participants also completed personality questionnaires, especially the Sensation Seeking Scales Form V. Results revealed a positive correlation between SS and augmenting/reducing in healthy controls, thereby replicating earlier findings. Bipolar depressed patients showed larger P1/N1 slopes than healthy controls, when medication was statistically controlled. Unipolar depressed patients showed smaller P2 slopes, but only when medication was not controlled. Implications of these results for further research on augmenting/reducing and affective disorders and their relationship to SS are discussed.

The paper documents the resettlement process undertaken following the 2011 heavy rains in Dar es Salaam City, which adversely affected many people who lived in flood prone areas particularly in and along Msimbazi river valley. Within the resettlement process, challenges which were encountered by different actors during the resettlement process were investigated. With the use of qualitative and quantitative data, the paper shows that the resettlement of households from Msimbazi River Valley to Mabwepande followed a number of steps decided during the process with no predetermined guidelines. The process largely centred around identifying those to be resettled, relocating them to the resettlement area and issuing alternative plots. The physical, economic, social, cultural and environmental dimensions of resettlement were less coherent in the process. Subsequently, the process resulted into both negative and positive outcomes, which are persistent until today. These include poor housing conditions, disruption of economic and income generating activities, unreliable social and technical infrastructure services, inability and or reluctance to develop the new plots and low living standards. However, high level of tenure security and certainty of being free from flood risk are some positive outcomes of the resettlement. The paper argues that the implementation of resettlement projects with no well-articulated process that takes care of the environmental, spatial, economic and social needs of the resettled population obscures the outcomes of the project. It therefore calls for caution when planning and implementing disaster led resettlement projects that necessary steps ought to be carried out to protect and enhance the wellbeing and livelihoods of those resettled apart from issuing alternative parcels of land.

Rapid urbanization and climate change are compounding the vulnerability of the urban poor to natural hazards, particularly in the global south. Large number of the population in cities of developing countries live in informal settlements characterized with lack of infrastructure facilities and services. Majority of the informal settlements are located in risk areas such as low-lying lands and river banks whereby climatic threats associated with flooding are common. The urban informal settlements are thus disproportionately more vulnerable due to their greater exposure associated with their geophysical location, under-invested infrastructure facilities as well as poor housing quality. While it is widely acknowledged that the need to adapt to climate change related hazards such as flooding is no longer an option, literature suggests that potentials and opportunities for adaptation are unevenly distributed among global regions, communities, sectors, ecological systems as well as across different time periods. This study sought to explore the potentials and limits of households living in flood prone in an informal settlement of Magomeni Suna, Dar es Salaam Tanzania. The study employed a mixed method research design using both quantitative and qualitative data collection and analysis. Quantitative data were collected through a structured questionnaire administered to 199 randomly selected respondents, while non participant observation was used to capture information related to household physical adaptation measures. Key informant interviews were used to elicit data from purposively selected representatives of government and other local institutions. Two focus group discussions supplemented the data collected through the other methods. The results show that households employ multiple options for flood adaptation ranging from structural measures aimed at preventing flood water from entering the houses, to action oriented strategies How to cite this paper:

Lake Kitangiri in Singida, Tanzania is facing enormous pressure as a result of overfishing, illegal fishing, and environmental degradation. The increase in population and climate change have caused a shift from dependency on economic activities such as crop cultivation and livestock keeping to fishing. The limited fish resources are over utilized and have been depleted due to increased fishing activities. In order to determine trends of fish production at Lake Kitangiri and the associated effects of overexploitation, a study was carriedout. Data were collected using household questionnaires, focus group discussion and key informants interviews. fish production, output of farming activities in Lake Kitangiri were found to have been decreasing over years. More importanly, fishing activities in the area have intensified due to influx of people to the area. Illegal fishing activities at the habitat for fish breeding have led to the depletion of fish in the lake. The findings suggest that the depletion of fishery resources has negative effects to the income of the Original Research Article
