Water use options for regional development : potentials of new water technologies in Central Northern Namibia

The CuveWaters project relates the alignment and implementation of innovative water technologies to an Integrated Water Resources Management (IWRM) in the Cuvelai-Etosha-Basin, which lies in Central Northern Namibia. The aim here is to improve inhabitants’ living conditions by means of appropriate technical schemes and measures – particularly with a view to enhancing water supply and basic sanitation (incl. waste water disposal). A focal part of Cuve-Waters concerns the re-use of water, efficient use of water and utilisation of different water qualities for different purposes (multi-resource mix). With respect to urban conditions and the problems of adequate supply and sanitation, the prospect of a semi-decentralised infrastructure system is under investigation, a concept which includes rainwater utilisation as well as waste water collection and treatment. One major option for such systems, in which waste water is considered a valuable resource, is a washing house combining effective waste water collection (vacuum sewer) with high-tech separation techniques (generation of energy, nutrients and waste water processing). Cleaned waste water – free of bacteria, viruses or pathogens – and fertiliser from an anaerobic waste water treatment plant can be re-used for irrigation in small scale agriculture to enhance food security and/or generate alternative income through the marketing of fresh produce. Energy, in the form of biogas, can be used for cooking or lighting. On the rural sites of the study area, adequate water supply poses a major challenge, for which three technology options are investigated here: rainwater harvesting, solar-coupled desalination of brackish groundwater, and managed aquifer recharge. Suitable technology options are selected for different sites in a participatory process (cf. CuveWaters Project 2008a, CuveWaters Project 2008b). Thus, general aims of the project in terms of providing regional economic impetus and improving livelihoods are: - to link integrated water resources management to land issues, develop the technology needed to build capacity, and achieve better governance; - to bring together supply- and demand-driven approaches in developing the infrastructure; - to consider water as related to other resources (land, energy, nutrients) and other fields of sustainability such as poverty reduction, equality and regional development. From these project objectives arise the key questions driving the surveys documented in this paper: what impetus for regional development can be expected from the implementation of technological options selected for the CuveWaters project? What constraints and obstacles need to be considered here, particularly in terms of incorporating the technologies into strategies of IWRM? What conclusions can be drawn when it comes to the supervision of implementation (training, capacity building, governance)? After an introduction the economic and social situation in the Cuvelai-Etosha Basin along with the conditions for urban agriculture is outlined. This is followed by the discussion of the potentials for water-related activities in the region, taking into account additional water uses and the operation and development of infrastructures, whilst investigating the potentials of urban agriculture for Central Northern Namibia. Finally, these potentials are summarized and conclusions pertaining to flanking measures for technical implementation are drawn

Domestic insurers in Poland and the global crisis

The article contains the analysis of the impact of global crisis on Polish insurance sector. The main areas of the crisis impact on the activity of Polish insurance companies has so far been the change in the assets value and the associated decline in the profitability of investment activity. The danger arising from the economic downturn has not been realized so far in the Polish insurance sector. Although the premium written is high, the structure of the portfolio in life insurances is changing. In 2008, however, a significant retreat from saving insurance policies with capital funds in the direction of structured products is observed. A significant increase in premiums written resulted in a good financial situation of Polish insurance companies. Despite the turmoil in financial markets it also seems that solvency of Polish insurance sector is unthreatened as measured by statutory ratios.insurance companies, Polish insurance market, global crisis

POIReviewQA: A Semantically Enriched POI Retrieval and Question Answering Dataset

Many services that perform information retrieval for Points of Interest (POI) utilize a Lucene-based setup with spatial filtering. While this type of system is easy to implement it does not make use of semantics but relies on direct word matches between a query and reviews leading to a loss in both precision and recall. To study the challenging task of semantically enriching POIs from unstructured data in order to support open-domain search and question answering (QA), we introduce a new dataset POIReviewQA. It consists of 20k questions (e.g."is this restaurant dog friendly?") for 1022 Yelp business types. For each question we sampled 10 reviews, and annotated each sentence in the reviews whether it answers the question and what the corresponding answer is. To test a system's ability to understand the text we adopt an information retrieval evaluation by ranking all the review sentences for a question based on the likelihood that they answer this question. We build a Lucene-based baseline model, which achieves 77.0% AUC and 48.8% MAP. A sentence embedding-based model achieves 79.2% AUC and 41.8% MAP, indicating that the dataset presents a challenging problem for future research by the GIR community. The result technology can help exploit the thematic content of web documents and social media for characterisation of locations

HIV Transmission and Injection Drug Use: Lessons From the Indiana Outbreak

A recent outbreak of HIV infection centered in the rural town of Austin in Scott County, Indiana, was associated with widespread injection drug use and a socio-economically depressed population. Control of the outbreak required coordinated efforts by state, federal, local, and academic institutions to implement and maintain on-site programs and services that included contact tracing, HIV and hepatitis C virus testing, insurance enrollment, syringe exchange, rehabilitation services, care coordination, preexposure prophylaxis, and HIV treatment. This article summarizes a presentation by Diane M. Janowicz, MD, at the IAS-USA continuing education program, Improving the Management of HIV Disease, held in Los Angeles, California, in April 2016
