    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

    Get PDF
    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

    Adolescent Adventures in Geology: Impacts of Geoscience-focused STEM Education Combined with Recreation Activities on Adolescents’ Perceived Self-Efficacy

    Quality, informal learning techniques combined with outdoor adventure recreation, or adventure STEM programming, is a potentially powerful complement to and extension of formal education (Fu et al., 2015). To address this underexplored field, West Virginia University (WVU) and the United States Geological Survey (USGS) partnered to create a geology STEM, outdoor adventure recreation camp. This thesis research project employed qualitative directed content analysis to examine the potential impacts of this adventure STEM program on participants’ perceptions of their outdoor recreation (OR) self-efficacy (Bandura, 1994; Mittelstaedt et al., 2009). Semi-structured interviews were conducted with 15 adolescent participants with an average age of 15 years. The camp program involved adventure activities combined with outdoor and in-class geology-focused informal learning. The curriculum employed was designed using a theoretical framework involving Experiential Education Theory (Kolb, 1984) and Self-Efficacy Theory (Bandura). Participants completed an eight-day adventure STEM program which involved recreation activities such as hiking, rock climbing, whitewater rafting, zip lining, environmental education, biking, fossil hunting, and geocaching. Lessons focused on geologic mapping, basic geologic concepts, historical geology of the Appalachian Mountains, and hydrology and environmental geology. Qualitative, directed content analysis of interviews show results indicating that there was a change in outdoor recreation self-efficacy beliefs due to experiences which took place at the camp program and that campers each had unique experiences related to the main sources and processes of self-efficacy, especially in the context of OR activities and experiences. These described experiences aligned with Bandura’s (1977) main sources of self-efficacy and the physiological processes reported fit with his described processes through which self-efficacy beliefs are formed. Notably, the following factors most often impacted all interviewed participants’ perceptions and beliefs about their OR-related self-efficacy: confidence levels, the perceived challenge of activities, self-described strong motivation levels to participate in OR activities, coping abilities related to difficult or risky OR activities, previous experiences, and a high interest in OR activities prior to attending the camp

    Philosophical Foundations of GeoAI: Exploring Sustainability, Diversity, and Bias in GeoAI and Spatial Data Science

    Full text link
    This chapter presents some of the fundamental assumptions and principles that could form the philosophical foundation of GeoAI and spatial data science. Instead of reviewing the well-established characteristics of spatial data (analysis), including interaction, neighborhoods, and autocorrelation, the chapter highlights themes such as sustainability, bias in training data, diversity in schema knowledge, and the (potential lack of) neutrality of GeoAI systems from a unifying ethical perspective. Reflecting on our profession's ethical implications will assist us in conducting potentially disruptive research more responsibly, identifying pitfalls in designing, training, and deploying GeoAI-based systems, and developing a shared understanding of the benefits but also potential dangers of artificial intelligence and machine learning research across academic fields, all while sharing our unique (geo)spatial perspective with others.Comment: Final Draf

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

    Get PDF
    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
