  1. USA spearheads renewed efforts to combat AIDS.

    2000-01-15

    This article presents the renewed efforts made by the US against AIDS. US Vice-President Al Gore claimed a US$150 million investment to help combat the international AIDS pandemic and contribute to international infectious disease control efforts. Likewise, the US will invest another US$100 million in HIV and AIDS prevention and treatment in Africa and Asia. It was also proposed that the US government would allocate US$325 million in the 2001 budget for worldwide HIV/AIDS prevention measures. Gore also promised that US$50 million would be allocated in February 2000 for funding, research, purchase and distribution of vaccines, as well as funding for militaries to prevent the spread of AIDS. Despite the increase in budget, the World Bank claims that the resources are inadequate for the fight against the epidemic. An annual allocation of US$1-2.3 billion would be necessary for AIDS prevention in Africa and currently Africa is receiving only US$160 million/year in official assistance for HIV/AIDS. The impact of AIDS has created societal instability and fertile ground for both internal and cross-border conflict. It was emphasized that without economic and social hope the nation would not have peace, and AIDS undermines both. PMID:10675132

  2. Is international conservation aid enough?

    Bare et al (2015 Environ. Res. Lett. 10 125010) ask an important question: is international conservation enough? Since the 1990’s international conservation donors have spent over 3.4 billion on biodiversity conservation related projects in sub-Saharan Africa. Both donors and recipients have a right to know if this is effective. Surprisingly, this question is rarely asked. It is a difficult question—involving many rival social, environmental, and economic explanations. Bare, Kauffman and Miller uncover some interesting associations, supporting existing hypotheses and proposing their own: that conservation aid alone is insufficient to mitigate drivers of deforestation (and in some cases may even exacerbate forest loss). This controversial result warrants further investigation—but what is needed now is nuance and robustness in further analyses, to have more confidence in the critique and it’s implications for international conservation aid.

  3. Use of Land Use Land Cover Change Mapping Products in Aiding Coastal Habitat Conservation and Restoration Efforts of the Mobile Bay NEP

    The Mobile Bay region has undergone significant land use land cover change (LULC) over the last 35 years, much of which is associated with urbanization. These changes have impacted the region s water quality and wildlife habitat availability. In addition, much of the region is low-lying and close to the Gulf, which makes the region vulnerable to hurricanes, climate change (e.g., sea level rise), and sometimes man-made disasters such as the Deepwater Horizon (DWH) oil spill. Land use land cover change information is needed to help coastal zone managers and planners to understand and mitigate the impacts of environmental change on the region. This presentation discusses selective results of a current NASA-funded project in which Landsat data over a 34-year period (1974-2008) is used to produce, validate, refine, and apply land use land cover change products to aid coastal habitat conservation and restoration needs of the Mobile Bay National Estuary Program (MB NEP). The project employed a user defined classification scheme to compute LULC change mapping products for the entire region, which includes the majority of Mobile and Baldwin counties. Additional LULC change products have been computed for select coastal HUC-12 sub-watersheds adjacent to either Mobile Bay or the Gulf of Mexico, as part of the MB NEP watershed profile assessments. This presentation will include results of additional analyses of LULC change for sub-watersheds that are currently high priority areas, as defined by MB NEP. Such priority sub-watersheds include those that are vulnerable to impacts from the DWH oil spill, as well as sub-watersheds undergoing urbanization. Results demonstrating the nature and permanence of LULC change trends for these higher priority sub-watersheds and results characterizing change for the entire 34-year period and at approximate 10-year intervals across this period will also be presented. Future work will include development of value-added coastal habitat quality

  4. Economic growth, biodiversity loss and conservation effort.

    This paper investigates the relationship between economic growth, biodiversity loss and efforts to conserve biodiversity using a combination of panel and cross section data. If economic growth is a cause of biodiversity loss through habitat transformation and other means, then we would expect an inverse relationship. But if higher levels of income are associated with increasing real demand for biodiversity conservation, then investment to protect remaining diversity should grow and the rate of biodiversity loss should slow with growth. Initially, economic growth and biodiversity loss are examined within the framework of the environmental Kuznets hypothesis. Biodiversity is represented by predicted species richness, generated for tropical terrestrial biodiversity using a species-area relationship. The environmental Kuznets hypothesis is investigated with reference to comparison of fixed and random effects models to allow the relationship to vary for each country. It is concluded that an environmental Kuznets curve between income and rates of loss of habitat and species does not exist in this case. The role of conservation effort in addressing environmental problems is examined through state protection of land and the regulation of trade in endangered species, two important means of biodiversity conservation. This analysis shows that the extent of government environmental policy increases with economic development. We argue that, although the data are problematic, the implications of these models is that conservation effort can only ever result in a partial deceleration of biodiversity decline partly because protected areas serve multiple functions and are not necessarily designated to protect biodiversity. Nevertheless institutional and policy response components of the income biodiversity relationship are important but are not well captured through cross-country regression analysis.

  7. Conservation and aid: designing more effective investments in natural resource governance reform.

    PubMed

    Nelson, Fred

    2009-10-01

    Biodiversity conservation outcomes are closely related to the rules and institutions governing resource use. Creating local incentives for conservation through more secure resource tenure is central to conservation outcomes on private and communal lands, where the preponderance of biodiversity occurs. Conservation efforts in sub-Saharan Africa are therefore centrally concerned with governance dynamics and institutional reform processes, such as the decentralization of property rights, and how best to achieve such reforms. Traditional mechanisms for financing conservation efforts in Africa rely heavily on funds channeled through multilateral and bilateral aid agencies. The history of development aid highlights a range of constraints these aid agencies face in terms of working toward more effective resource governance arrangements and promoting reforms. Government aid agencies possess incentives for promoting large-scale and short-term projects that maximize expenditure volumes and tend to define issues in technical rather than political terms. The history of development aid suggests that these and other characteristics of aid agencies impedes their ability to influence governance reform processes and that aid funding may discourage the adoption of reforms. Greater emphasis in African conservation financing needs to be placed on flexible, small-scale investments aligned to local interests and constituencies that prioritize innovation, learning, and experimentation. Additionally, more research is required that explores the linkages between conservation funding, donor decision-making processes, and governance reforms. PMID:19765032

    Countries in eastern Africa have set aside significant proportions of their land for protection. But are these areas representative of the diverse range of species and habitats found in the region? And do conservation efforts include areas where the state of biodiversity is likely to deteriorate without further interventions? Various studies have addressed these questions at global and continental scales. However, meaningful conservation decisions are required at finer geographical scales. To operate more effectively at the national level, finer scale baseline data on species and on higher levels of biological organization such as the eco-regions are required, among other factors. Here we adopted a recently developed high-resolution potential natural vegetation (PNV) map for eastern Africa as a baseline to more effectively identify conservation priorities. We examined how well different potential natural vegetations (PNVs) are represented in the protected area (PA) network of eastern Africa and used a multivariate environmental similarity index to evaluate biases in PA versus PNV coverage. We additionally overlaid data of anthropogenic factors that potentially influence the natural vegetation to assess the level of threat to different PNVs. Our results indicate substantial differences in the conservation status of PNVs. In addition, particular PNVs in which biodiversity protection and ecological functions are at risk due to human influences are revealed. The data and approach presented here provide a step forward in developing more transparent and better informed translation from global priorities to regional or national implementation in eastern Africa, and are valid for other geographic regions.

  9. Subpopulation triage: how to allocate conservation effort among populations.

    Threatened species often exist in a small number of isolated subpopulations. Given limitations on conservation spending, managers must choose from strategies that range from managing just one subpopulation and risking all other subpopulations to managing all subpopulations equally and poorly, thereby risking the loss of all subpopulations. We took an economic approach to this problem in an effort to discover a simple rule of thumb for optimally allocating conservation effort among subpopulations. This rule was derived by maximizing the expected number of extant subpopulations remaining given n subpopulations are actually managed. We also derived a spatiotemporally optimized strategy through stochastic dynamic programming. The rule of thumb suggested that more subpopulations should be managed if the budget increases or if the cost of reducing local extinction probabilities decreases. The rule performed well against the exact optimal strategy that was the result of the stochastic dynamic program and much better than other simple strategies (e.g., always manage one extant subpopulation or half of the remaining subpopulation). We applied our approach to the allocation of funds in 2 contrasting case studies: reduction of poaching of Sumatran tigers (Panthera tigris sumatrae) and habitat acquisition for San Joaquin kit foxes (Vulpes macrotis mutica). For our estimated annual budget for Sumatran tiger management, the mean time to extinction was about 32 years. For our estimated annual management budget for kit foxes in the San Joaquin Valley, the mean time to extinction was approximately 24 years. Our framework allows managers to deal with the important question of how to allocate scarce conservation resources among subpopulations of any threatened species. PMID:18477029

    Conservation and development are intricately linked. The international donor community has long provided aid to tropical countries in an effort to alleviate poverty and conserve biodiversity. While hundreds of millions of $ have been invested in over 500 environmental-based projects in Madagascar during the period covered by a series of National Environmental Action Plans (1993-2008) and the protected areas network has expanded threefold, deforestation remains unchecked and none of the eight Millennium Development Goals (MDGs) established for 2000-2015 were likely be met. Efforts to achieve sustainable development had failed to reduce poverty or deliver progress toward any of the MDGs. Cross-sectorial policy adjustments are needed that (i) enable and catalyze Madagascar's capacities rather than deepening dependency on external actors such as the World Bank, the International Monetary Fund and donor countries, and that (ii) deliver improvements to the livelihoods and wellbeing of the country's rural poor.

Most important are the exclusion of one-half the original data without a discussion of selection bias, the lack of model adjustment for either population growth or migration, and the crude classifications of land cover and protected areas that lead to aggregation bias.1 Of greater significance, we stress the need for caution in the interpretation of data that could have profound effects on regional land use decisions.

    Amphibians epitomize the modern biodiversity crisis, and attract great attention from the scientific community since a complex puzzle of factors has influence on their disappearance. However, these factors are multiple and spatially variable, and declining in each locality is due to a particular combination of causes. This study shows a suitable statistical procedure to determine threats to amphibian species in medium size administrative areas. For our study case, ten biological and ecological variables feasible to affect the survival of 15 amphibian species were categorized and reduced through Principal Component Analysis. The principal components extracted were related to ecological plasticity, reproductive potential, and specificity of breeding habitats. Finally, the factor scores of species were joined in a presence-absence matrix that gives us information to identify where and why conservation management are requires. In summary, this methodology provides the necessary information to maximize benefits of conservation measures in small areas by identifying which ecological factors need management efforts and where should we focus them on.

    Species distribution models are used for numerous purposes such as predicting changes in species’ ranges and identifying biodiversity hotspots. Although implications of distribution models for conservation are often implicit, few studies use these tools explicitly to inform conservation efforts. Herein, we illustrate how multiple distribution models developed using distinct sets of environmental variables can be integrated to aid in identification sites for use in conservation. We focus on the endangered arroyo toad (Anaxyrus californicus), which relies on open, sandy streams and surrounding floodplains in southern California, USA, and northern Baja California, Mexico. Declines of the species are largely attributed to habitat degradation associated with vegetation encroachment, invasive predators, and altered hydrologic regimes. We had three main goals: 1) develop a model of potential habitat for arroyo toads, based on long-term environmental variables and all available locality data; 2) develop a model of the species’ current habitat by incorporating recent remotely-sensed variables and only using recent locality data; and 3) integrate results of both models to identify sites that may be employed in conservation efforts. We used a machine learning technique, Random Forests, to develop the models, focused on riparian zones in southern California. We identified 14.37% and 10.50% of our study area as potential and current habitat for the arroyo toad, respectively. Generally, inclusion of remotely-sensed variables reduced modeled suitability of sites, thus many areas modeled as potential habitat were not modeled as current habitat. We propose such sites could be made suitable for arroyo toads through active management, increasing current habitat by up to 67.02%. Our general approach can be employed to guide conservation efforts of virtually any species with sufficient data necessary to develop appropriate distribution models. PMID:26125634

    871 of Singapore's 3.1 million people have been diagnosed with HIV since 1985. 90% of these people are male and more than 70% of them report that they were infected through unprotected heterosexual sex. In the context of a growing number of people with AIDS, the government of Singapore plans to begin promoting condom use rather than rely simply upon campaigns stressing the need to remain sexually faithful to one partner. The government plans to increase awareness of HIV/AIDS at the grassroots, and gradually include condom use in public campaigns which now focus upon avoiding casual sex. At Singapore's first national AIDS conference, participants shared studies which showed that although a majority of Singaporeans know that HIV/AIDS is largely transmitted through sex or the sharing of injection equipment in IV drug use, up to 40% worry that they can become infected in other ways, such as from a diseased person sneezing or coughing upon them.

    PubMed

    1993-10-25

    On or around November 1, 1993, the Clinton administration plans to send its proposal to Congress for reforming foreign aid; significant changes could result in the international population assistance program. The Foreign Assistance Act (FAA) of 1961 is currently too unwieldy to allow the efficient implementation of US foreign policy, especially in the area of development assistance. New international priorities must be established and new role given to the US now that the Cold War has ended. The US Agency for International Development is therefore rewriting the FAA and reorganizing in-house with the objective of streamlining and updating the purposes and objectives of foreign aid. Development assistance would be replaced by a section on sustainable development designed to promote economic growth, preserve the global environment, support democratic participation, and stabilize world population growth. This bill would also emphasize the special role of women in development while stressing the importance of nongovernmental organizations as essential in formulating and implementing policies and programs. This plan is regarded as attractive and may be the last major overhaul of the FAA for another 30 years. It remains to be seen, however, how deep and how far changes will go, but it may be said that significant change is inevitable and that serious potential exists for improvement.

    In college and university residence halls, resident assistants (RAs) are expected to serve as first-aid providers to students who may have alcohol, other drug, mental health, and academic problems. Despite this responsibility, evidence-based, first-aid programs have not been developed and tested for the RA workforce. The current study examined effects of an investigational first-aid program designed specifically for RAs. The online Peer Hero Training program is a novel approach to RA training in its use of interactive video dramatizations of incidents involving substance-using or distressed residents. A 9-month randomized trial conducted on eight US campuses compared RAs who participated in the Peer Hero Training program to RAs who received training-as-usual. Participation in the Peer Hero Training program significantly increased RA first-aid efforts for residential students who may have had alcohol, other drug, mental health, or academic problems 6 months after baseline. Compared with those in the training-as-usual condition, RAs in the Peer Hero Training program made more than 10 times as many first-aid efforts for possible alcohol problems, almost 14 times the number of first-aid efforts for possible drug use, almost 3 times the number of first-aid efforts for possible mental health problems, and 3 times the number of first-aid efforts for academic problems. There was no evidence that measured RA attitudes mediated the effects of the intervention. Results of this preliminary evaluation trial suggest that online training using interactive video dramatizations is a viable approach to strengthening RAs' ability to provide alcohol, other drugs, and mental health first-aid to undergraduates.

Results of this preliminary evaluation trial suggest that online training using interactive video dramatizations is a viable approach to strengthening RAs’ ability to provide alcohol, other drug, and mental health first-aid to undergraduates.

    Protected areas are crucial for tropical forest conservation efforts. Estimation of the effectiveness of protected areas is thus important for evaluating the efficacy of forest conservation policies and priorities. However, comprehensive evaluation of the long-term effects of Protected Areas and international aid is lacking. However, with the recent availability of long-term, large-scale forest cover change data at 30-m resolution, it has become possible to address some of the issues surrounding the effectiveness of protected areas. To evaluate the effectiveness of Protected Areas in the pan-tropics and international aid for conservation, we use the 30m resolution data along with econometrics 1) to estimate avoided deforestation by PAs in the tropics during the 2000s, 2) estimate effects of international aid on avoided deforestation by PAs and 3) analyze the relationships between the socio-economic variables and increases in deforestation, avoided deforestation by PAs and effects of international aid. Our results show that protected areas avoided 83,500 ± 21,200 km2 of deforestation during the 2000s. Brazil showed the highest estimates of effects of international aid on the avoided deforestation of 22 m2/USD, which is about 50 times higher compared to Indonesia (0.5 m2/USD). The regression analysis between avoided deforestation, effects of international aid and socio-economic factors demonstrates that PAs have been relatively more effective in the countries where the deforestation pressures were increasing and that governance and forest change monitoring capacity may be important factors enhancing the efficacy of international aid. Our study presents the first pan-tropical analysis of the long-term evaluation of the effectiveness of protected areas, international aid and their regulating factors using spatially explicit fine resolution data. Our findings allow us to pinpoint where conservation initiatives and resource management are effectively practiced and to

    In the absence of a cure or vaccine for acquired immune deficiency syndrome (AIDS) educational and social marketing efforts to reduce the transmission of Human T-lymphotropic type III/lymphadenopathy-associated virus (HTLV-III/LAV) are currently our best hope for controlling the disease. Since 1983, the Centers for Disease Control (CDC) has funded a series of research studies to determine whether education efforts can successfully motivate the adoption of key behaviors relevant to the control of a variety of sexually transmitted diseases (STDs). Analysis of the first two studies which are now completed, and preliminary data from a third study, have documented dramatic changes in behavior, knowledge, and attitudes among clients in inner-city public health clinics. The authors describe the principles and underlying assumptions that have guided the design of their STD initiatives, drawing special attention to the implications for AIDS health education efforts.

    Efforts to expand protected area networks are limited by the costs of managing protected sites. Volunteers who donate labor to help manage protected areas can help defray these costs. However, volunteers may be willing to donate more labor to some protected areas than others. Understanding variation in volunteering effort would enable conservation organizations to account for volunteer labor in their strategic planning. We examined variation in volunteering effort across 59 small protected areas managed by Yorkshire Wildlife Trust, a regional conservation nonprofit in the United Kingdom. Three surveys of volunteering effort reveal consistent patterns of variation across protected areas. Using the most detailed of these sources, a survey of site managers, we estimate that volunteers provided 3200 days of labor per year across the 59 sites with a total value exceeding that of paid staff time spent managing the sites. The median percentage by which volunteer labor supplements management costs on the sites was 36%. Volunteering effort and paid management costs are positively correlated, after controlling for the effect of site area. We examined how well a range of characteristics of the protected areas and surrounding communities explain variation in volunteering effort. Protected areas that are larger have been protected for longer and that are located near to denser conurbations experience greater volunteering effort. Together these factors explain 38% of the observed variation in volunteering effort across protected areas.

    The role that human rights can play in the global response to HIVIAIDS is crucial. People around the world continue to be placed at risk of HIV due to ongoing human rights violations. In this article--based on a public lecture he gave at "From Evidence and Principle to Policy and Action", the 2nd Annual Symposium on HIV, Law and Human Rights, held on 10-12 June 2010 in Toronto, Canada--Michel Kazatchkine, Executive Director of the Global Fund to Fight AIDS, Tuberculosis and Malaria, discusses how the lack of support for programs that protect and promote human rights is one of the failures in the response to AIDS. He stresses that advocates must reinvigorate efforts for human rights and treatment and prevention for all, including for the most marginalized populations.

    Bald eagle (Haliaeetus leucocephalus) conservation in Arizona, USA, is a prime example of a successful, cooperative environmental management effort. The Salt River Project (SRP) is an active participant in the statewide bald eagle management activities. This paper summarizes the major components of the statewide program and highlights SRP`s participation in these efforts. The Southwestern Bald Eagle Management Committee (SWBEMC) was formed as a means of coordinating interagency projects. Chaired by the Arizona Game and Fish Department (AGFD), the SWBEMC is comprised of 15 state, federal, tribal, and private agencies. Together, these agencies sponsor the Nest Watch Program, a unique and effective program dedicated to the study, conservation, and recovery of bald eagles in the southwest. Other significant components of the bald eagle management program include nest monitoring, nest search activities, winter counts, and demography studies. 7 refs., 4 figs.

    China has approximately 5.80×10(6)ha coastal wetlands by 2014, accounting for 10.82% of the total area of natural wetlands. Healthy coastal wetland ecosystems play an important role in guaranteeing the territory ecological security and the sustainable development of coastal zone in China. In this paper, the natural geography and the past and present status of China's coastal wetlands were introduced and the five stages (1950s-1970s, 1980s-1991, 1992-2002, 2003-2010 and 2011-present) of China's coastal wetlands conservation from the foundation of the People's Republic in 1949 to present were distinguished and reviewed. Over the past decades, China has made great efforts in coastal wetland conservation, as signified by the implementation of coastal wetland restoration projects, the construction of coastal wetland nature reserves, the practice of routine ecological monitoring and two national wetland surveys, the promulgation of local wetland conservation statutes and specific regulations, the coordination mechanism to enhance management capacity, the wide development of coastal wetland research and public participation, and the extensive communication to strengthen international cooperation. Nonetheless, six major issues recently emerged in China's coastal wetland conservation are evidently existed, including the increasing threats of pollution and human activities, the increasing adverse effects of threaten factors on ecosystem function, the increasing threats of coastal erosion and sea-level rising, the insufficient funding for coastal wetlands conservation, the imperfect legal and management system for coastal wetlands, and the insufficient education, research and international cooperation. Although the threats and pressures on coastal wetlands conservation are still apparent, the future of China's coastal wetlands looks promising since the Chinese government understands that the sustainable development in coastal zone requires new attitudes, sound policies and

  16. Understanding Drought and Regional Conservation Efforts on Urban Ecohydrology in Southern California

    2015-12-01

    Cities in the western U.S. are under increasing pressure to reduce the demand of imported water through increasing conservation efforts, altering non-native landscapes, and enhancing local water supplies. The State of California adopted emergency regulations implementing a mandatory 25% statewide reduction in potable urban water use and agricultural restrictions have also been enacted. The complexities in urban water flows and lack of granular data make understanding the impact of conservation and demand change on regional ecohydrology difficult. This presentation highlights ongoing work to better understand the coupling between humans, water and ecosystems in semi-arid urban cities, using metropolitan southern California as a case study. We evaluate historical and contemporary ecohydrologic behavior and human impacts through intensive data collection, remote sensing and high resolution modeling. The change in outdoor irrigation rates due to recent conservation measures (2008-2010) has resulted in overall decreased greenness and reduced dry season streamflow; however significant variability in conservation response is observed. Groundwater recharge, artificially supported by landscape irrigation, is also being impacted. In general, anthropogenic water fluxes (irrigation, pipe leakage, spreading grounds) are not parameterized in hydrologic and land surface models applied over urban areas. Inclusion of landscape irrigation significantly improves neighborhood scale simulations of evaporative fluxes and land surface temperatures and results in shifts in the energy partitioning. The cooling effects of irrigation on daily air temperatures has the largest influence over low intensity residential areas, with an average 2°C decrease observed in coupled model simulations (WRF-Noah-UCM). Ultimately, we strive to improve predictions of human-water interactions in semi-arid cities to better understand the effectiveness and impacts of ongoing drought and conservation efforts

    A major challenge in conservation biology is the need to broadly prioritize conservation efforts when demographic data are limited. One method to address this challenge is to use population genetic data to define groups of populations linked by migration and then use demographic information from monitored populations to draw inferences about the status of unmonitored populations within those groups. We applied this method to anadromous alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis), species for which long-term demographic data are limited. Recent decades have seen dramatic declines in these species, which are an important ecological component of coastal ecosystems and once represented an important fishery resource. Results show that most populations comprise genetically distinguishable units, which are nested geographically within genetically distinct clusters or stocks. We identified three distinct stocks in alewife and four stocks in blueback herring. Analysis of available time series data for spawning adult abundance and body size indicate declines across the US ranges of both species, with the most severe declines having occurred for populations belonging to the Southern New England and the Mid-Atlantic Stocks. While all alewife and blueback herring populations deserve conservation attention, those belonging to these genetic stocks warrant the highest conservation prioritization. PMID:24567743

    The bonobo (Pan paniscus), a great ape that is endemic to the Democratic Republic of the Congo (DRC), has been listed as Endangered on the IUCN Red List since 2007. Hunting and habitat loss are primary threats. Two recent wars and ongoing conflicts in the DRC have resulted in political and economic instability that hampers on-the-ground work, thereby accentuating the importance of spatial data and maps as tools for monitoring threats remotely and prioritizing locations for safeguarding bonobo habitat. Several regional and rangewide efforts have leveraged the utility of existing spatial data to help focus limited resources for effective broad-scale conservation of these great apes. At local scales, we developed spatial models to identify locations of highest hunting pressure, predict future human settlement and agricultural expansion, map areas of highest conservation value to bonobos, and identify the connective corridors linking them. We identified 42 least-disturbed wildland blocks meeting the minimum home range size needed for bonobos, and 32 potential corridors. At the range-wide scale, we developed a first range-wide spatial model of suitable conditions for the bonobo; this was a major contribution to the development of a Bonobo Conservation Strategy for 2012-2022, recently published by IUCN. The model used a forest edge density metric and other biotic and abiotic variables in conjunction with bonobo nest data collected during 2003-2010 by over 40 bonobo researchers. Approximately 28% of the range was predicted suitable; of that, about 27.5% was located in official protected areas. Highlighting these examples, this presentation will discuss the conservation status of bonobos and how spatial data and models are being utilized for the formation of strategic conservation plans.

    To control illegal wildlife-product trade and protect endangered species of animals, unambiguous identification of the animal specimens is vitally important. Genetic approaches were adopted to identify animal species for conservation and to prevent their fraudulent misidentification in Taiwan, especially for samples of animal residues, powders, and processed products. PCR or nested PCR based on the nature of DNA was used for amplification of cyt b, COI, CHD, and D-loop DNA fragments. Sequences of these fragments were compared with those registered in DNA databases and phylogenetic analysis was performed. The established methods were applied in forensic cases for support of conservation efforts and they were proved to be robust. For conservation animal identification, various samples seized by law enforcement agents have been identified by our systems as rhinoceros horns, Indian sawback turtles, shahtoosh, ivories, dolphins, whales, etc. The systems were also successfully used in investigating the illegal trade of commercial turtle shells and the fraudulent misidentification of food contents on product labels in Taiwanese markets. This review summarizes the work conducted in our laboratory and describes the Taiwan experience.

  20. The role of the Wetland Reserve Program in conservation efforts in the Mississippi River Alluvial Valley

    The Mississippi River Alluvial Valley includes the floodplain of the Mississippi River from Cairo, Illinois, USA, to the Gulf of Mexico. Originally this region supported about 10 million ha of bottomland hardwood forests, but only about 2.8 million ha remain today. Furthermore, most of the remaining bottomland forest is highly fragmented with altered hydrologic processes. During the 1990s landscape-scale conservation planning efforts were initiated for migratory birds and the threatened Louisiana black bear (Ursus americanus luteolus). These plans call for large-scale reforestation and restoration efforts in the region, particularly on private lands. In 1990 the Food, Agriculture, Conservation and Trade Act authorized the Wetlands Reserve Program (WRP). The WRP is a voluntary program administered by the United States Department of Agriculture that provides eligible landowners with financial incentives to restore wetlands and retire marginal farmlands from agricultural production. As of 30 September 2005, over 275,700 ha have been enrolled in the program in the Mississippi River Alluvial Valley, with the greatest concentration in Louisiana, Arkansas, and Mississippi, USA. Hydrologic restoration is common on most sites, with open-water wetlands, such as moist-soil units and sloughs, constituting up to 30% of a given tract. Over 33,200 ha of open-water wetlands have been created, potentially providing over 115,000,000 duck-use days. Twenty-three of 87 forest-bird conservation areas have met or exceed core habitat goals for migratory songbirds and another 24 have met minimum area requirements. The WRP played an integral role in the fulfillment of these goals. Although some landscape goals have been attained, the young age of the program and forest stands, and the lack of monitoring, has limited evaluations of the program's impact on wildlife populations.

    Increased urban lighting on Kauai Island, Hawaii, has resulted in new problems for threatened and endangered procellariiform birds. Between 1978 and 1985,11,767 Kewell's shearwaters, 38 dark-rumped petrels, and 8 band-rumped storm petrels were attracted to bright urban lights, struck unseen objects, and fell to the ground. A salvage effort involving public cooperation and government-run 'aid stations' has returned 90% of these birds to the wild. Nightly fallout of seabirds was significantly reduced during the full moon, but fallout increased as the new moon approached. The heaviest fallout occurred in urban coastal areas, particularly at river mouths. More than 97% of the fallout involved fledgling birds apparently leaving their mountain nesting grounds for the first time. Less than 1%of these birds were recovered again on subsequent nights.

    The protection of key areas for biodiversity at sea is not as widespread as on land and research investment is necessary to identify biodiversity hotspots in the open ocean. Spatially explicit conservation measures such as the creation of representative networks of marine protected areas (MPAs) is a critical step towards the conservation and management of marine ecosystems, as well as to improve public awareness. Conservation efforts in ecologically rich and threatened ecosystems are specially needed. This is particularly urgent for the Mediterranean marine biodiversity, which includes highly mobile marine vertebrates. Here, we studied the at sea distribution of one of the most endangered Mediterranean seabird, the critically endangered Balearic shearwater Puffinus mauretanicus. Present knowledge, from vessel-based surveys, suggests that this species has a coastal distribution over the productive Iberian shelf in relation to the distribution of their main prey, small pelagic fish. We used miniaturised satellite transmitters to determine the key marine areas of the southern population of Balearic shearwaters breeding on Eivissa and spot the spatial connections between breeding and key marine areas. Our tracking study indicates that Balearic shearwaters do not only forage along the Iberian continental shelf but also in more distant marine areas along the North African coast, in particular W of Algeria, but also NE coast of Morocco. Birds recurrently visit these shelf areas at the end of the breeding season. Species distribution modelling identified chlorophyll a as the most important environmental variable in defining those oceanographic features characterizing their key habitats in the western Mediterranean. We identified persistent oceanographic features across time series available in the study area and discuss our results within the current conservation scenario in relation to the ecology of the species.

    Agricultural soil loss and deposition in aquatic ecosystems is a problem that impairs water quality worldwide and is costly to agriculture and food supplies. In the US, for example, billions of dollars have subsidized soil and water conservation practices in agricultural landscapes over the past decades. We used paleolimnological methods to reconstruct trends in sedimentation related to human-induced landscape change in 32 lakes in the intensively agricultural region of the Midwestern United States. Despite erosion control efforts, we found accelerating increases in sediment deposition from erosion; median erosion loss since 1800 has been 15.4 tons ha−1. Sediment deposition from erosion increased >6-fold, from 149 g m−2 yr−1 in 1850 to 986 g m−2 yr−1 by 2010. Average time to accumulate one mm of sediment decreased from 631 days before European settlement (ca. 1850) to 59 days mm−1 at present. Most of this sediment was deposited in the last 50 years and is related to agricultural intensification rather than land clearance or predominance of agricultural lands. In the face of these intensive agricultural practices, traditional soil conservation programs have not decelerated downstream losses. Despite large erosion control subsidies, erosion and declining water quality continue, thus new approaches are needed to mitigate erosion and water degradation. PMID:23326454

    Although there have been heated discussions concerning the relative importance of using Mhc diversity as a basis for selecting breeders in conservation projects, most parties agree that the genetic variability residual in an endangered species should be maintained through genetic management, if at all possible. Substantial evidence exists (particularly in birds) documenting the influences of specific Mhc haplotypes on disease outcome and also that those individuals which are heterozygous for Mhc alleles appear to have an advantage for survival over those that are homozygous. Thus, conservation of genetic variability of the Mhc is likely important for the preservation of fitness, especially in small breeding populations. More than half of the world's crane species are listed as endangered. Members of all 15 known species are represented among breeding animals for captive propagation at the International Crane Foundation (Wisconsin) and the USGS Patuxent Wildlife Research Center (Maryland). Collaborative multi-organization efforts and the availability of extensive pedigree records have allowed the study of Mhc variability in several species of cranes. We have found, for example, that Mhc diversity in the captive Florida sandhill crane (Grus canadensis pratensis) population appears high, whereas in the captive whooping crane (Grus americana), which has undergone a severe 'genetic bottleneck,? both the number of alleles and the levels of heterozygosity appear to be substantially reduced.

    Abstract The government of Botswana has been spending a lot of money in the prevention, treatment, care and support for HIV/AIDS patient for decades. This paper uses data from the third Botswana AIDS Impact Survey (BAIS III) to explore high-risk behaviors of adults and how they affect government efforts to stop the spread of HIV/AIDS. The objective of this paper is to fill in the gap on the assessment of high-risk behaviors associated with HIV/AIDS and their implications on HIV/AIDS prevention efforts. A nationally representative sample of 10,159 men and women aged 20–64 years who had successfully completed the BAIS III individual questionnaire were used in the study. Both descriptive and binary logistic regression analyses were used for analysis. Crude odds ratios were obtained from gross effects model while adjusted odds ratios (AOR) were obtained from the net effects model. Statistically significant association was observed between multiple current partners and alcohol consumption (AOR = 1.5), drug abuse (AOR = 1.7), transactional sex (AOR = 2.6) and intergenerational sex (AOR = 1.07). Furthermore, statistically significant association was seen for inconsistent condom use and having tested for HIV (AOR = 1.5). These results show a worrying tendency that despite government's efforts to stop the spread of HIV/AIDS, adults in Botswana continue to indulge in high-risk behaviors. Therefore, any programs and policies on HIV/AIDS should first target these high-risk behaviors. PMID:25293869

    In the face of unprecedented global biodiversity loss, conservation planning must balance between refining and deepening knowledge versus acting on current information to preserve species and communities. Phylogenetic diversity (PD), a biodiversity measure that takes into account the evolutionary relationships between species, is arguably a more meaningful measure of biodiversity than species diversity, but cannot yet be applied to conservation planning for the majority of taxa for which phylogenetic trees have not yet been developed.

  12. Assessing the impact of international conservation aid on deforestation in sub-Saharan Africa

    International conservation donors have spent at least 3.4 billion to protect biodiversity and stem tropical deforestation in Africa since the early 1990s. Despite more than two decades of experience, however, there is little research on the effect of this aid at a region-wide scale. Numerous case studies exist, but show mixed results. Existing research is usually based on community perception or focused on short-term donor objectives rather than specific conservation outcomes, like deforestation rates. Thus, the impact of billions of dollars of conservation aid on deforestation rates remains an open question. This article uses an original dataset to analyze the effect of international conservation aid on deforestation rates in 42 African countries between 2000 and 2013. We first describe patterns of conservation aid across the continent and then assess its impact (with one to five-year lags), controlling for other factors that may also affect deforestation, including rural population, protected areas (PAs), governance, and other economic and commodity production variables. We find that conservation aid is associated with higher rates of forest loss after one- or two-year lags. A similar result holds for PA extent, suggesting possible displacement of deforestation from PAs. However, governance quality in high forest cover countries moderates these effects such that deforestation rates are reduced. Rural population is the most consistent factor associated with forest loss, confirming previous studies of this driver. Our results suggest that in heavily forested countries, development projects designed to support conservation work initially in conditions of good governance, but that conservation aid alone is insufficient to mitigate larger deforestation drivers.

    Introduction The HIV/AIDS epidemic in America is rapidly progressing in certain subpopulations, including African-American and Hispanic communities. Churches may provide a means for reaching high-risk minority populations with effective HIV/AIDS prevention. We report on a series of focus group interviews conducted with Utah clergy who primarily serve African American and Hispanic congregations. Methods A total of three focus groups (two with Catholic clergy serving Hispanic congregations and one with protestant clergy serving African American congregations) were conducted with eleven participants, lasting approximately two hours each. Each focus group was audio-recorded and transcribed for analysis. Analysis of the data was conducted using a modified grounded theory approach. Results There were remarkable similarities in the attitudes and beliefs among all clergy participating in this study regarding HIV/AIDS and church-based prevention programs. All groups expressed concern about the diseases as a global epidemic and reported that the disease is highly preventable. Also, participants indicated a sense of responsibility to address the issues surrounding HIV/AIDS-related prevention, testing and care within their theological framework. Conclusion HIV/AIDS prevention and care for the infected are seen as falling within the scope of religious organizations. Openness to expanding efforts in this regard was shared by clergy participating in this study. Approaching religious leaders with tailored approaches that respect the values and practices of their particular religions will be more effective than attempting to impose approaches that do not achieve this standard.

    Conservation prioritization usually focuses on conservation of rare species or biodiversity, rather than ecological processes. This is partially due to a lack of informative indicators of ecosystem function. Biological soil crusts (BSCs) trap and retain soil and water resources in arid ecosystems and function as major carbon and nitrogen fixers; thus, they may be informative indicators of ecosystem function. We created spatial models of multiple indicators of the diversity and function of BSCs (species richness, evenness, functional diversity, functional redundancy, number of rare species, number of habitat specialists, nitrogen and carbon fixation indices, soil stabilization, and surface roughening) for the 800,000-ha Grand Staircase-Escalante National Monument (Utah, U.S.A.). We then combined the indicators into a single BSC function map and a single BSC biodiversity map (2 alternative types of conservation value) with an unweighted averaging procedure and a weighted procedure derived from validations performance. We also modeled potential degradation with data from a rangeland assessment survey. To determine which areas on the landscape were the highest conservation priorities, we overlaid the function- and diversity-based conservation-value layers on the potential degradation layer. Different methods for ascribing conservation-value and conservation-priority layers all yielded strikingly similar results (r = 0.89-0.99), which suggests that in this case biodiversity and function can be conserved simultaneously. We believe BSCs can be used as indicators of ecosystem function in concert with other indicators (such as plant-community properties) and that such information can be used to prioritize conservation effort in drylands. ?? 2008 Society for Conservation Biology.

    Formal methods can be applied to many of the development and verification activities required for civil avionics software. RTCA/DO-178B, Software Considerations in Airborne Systems and Equipment Certification, gives a brief description of using formal methods as an alternate method of compliance with the objectives of that standard. Despite this, the avionics industry at large has been hesitant to adopt formal methods, with few developers have actually used formal methods for certification credit. Why is this so, given the volume of evidence of the benefits of formal methods? This presentation will explore some of the challenges to using formal methods in a certification context and describe the effort by the Formal Methods Subgroup of RTCA SC-205/EUROCAE WG-71 to develop guidance to make the use of formal methods a recognized approach.

    Two new turbofan-powered transports currently undergoing flight testing, the Il-96-300 and the Tu-204, are believed to substantially owe their excellent fuel efficiencies to the research work conducted by the Central Aero-Hydrodynamic Institute in Moscow. This institute is responsible for the bulk of the USSR's aerodynamic, stability and control, aeroelasticity, and airframe structural characteristics research. As a measure of the quality of aerodynamic design achievable on the basis of these research efforts, it has been claimed that the Il-96-300 has a L/D value of 19 at Mach 0.92. The primary shortcoming of the institute is its poor hardware resources for CFD; these are compensated by the intensive development of sophisticated computer programs.

    Natural-resource managers and other conservation practitioners are under unprecedented pressure to categorize and quantify the vulnerability of natural systems based on assessment of the exposure, sensitivity, and adaptive capacity of species to climate change. Despite the urgent need for these assessments, neither the theoretical basis of adaptive capacity nor the practical issues underlying its quantification has been articulated in a manner that is directly applicable to natural-resource management. Both are critical for researchers, managers, and other conservation practitioners to develop reliable strategies for assessing adaptive capacity. Drawing from principles of classical and contemporary research and examples from terrestrial, marine, plant, and animal systems, we examined broadly the theory behind the concept of adaptive capacity. We then considered how interdisciplinary, trait- and triage-based approaches encompassing the oft-overlooked interactions among components of adaptive capacity can be used to identify species and populations likely to have higher (or lower) adaptive capacity. We identified the challenges and value of such endeavors and argue for a concerted interdisciplinary research approach that combines ecology, ecological genetics, and eco-physiology to reflect the interacting components of adaptive capacity. We aimed to provide a basis for constructive discussion between natural-resource managers and researchers, discussions urgently needed to identify research directions that will deliver answers to real-world questions facing resource managers, other conservation practitioners, and policy makers. Directing research to both seek general patterns and identify ways to facilitate adaptive capacity of key species and populations within species, will enable conservation ecologists and resource managers to maximize returns on research and management investment and arrive at novel and dynamic management and policy decisions.

    As conservation increases its emphasis on implementing change at landscape-level scales, multi-agency, cross-boundary, and multi-stakeholder networks become more important. These elements complicate traditional notions of learning. To investigate this further, we examined structures of learning in the Landscape Conservation Cooperatives (LCCs), which include the entire US and its territories, as well as parts of Canada, Mexico, and Caribbean and Pacific island states. We used semi-structured interviews, transcribed and analyzed using NVivo, as well as a charrette-style workshop to understand the difference between the original stated goals of individual LCCs and the values and purposes expressed as the collaboration matured. We suggest double-loop learning as a theoretical framework appropriate to landscape-scale conservation, recognizing that concerns about accountability are among the valid points of view that must be considered in multi-stakeholder collaborations. Methods from the social sciences and public health sectors provide insights on how such learning might be actualized.

    Conservation priorities for Prunus africana, a tree species found across Afromontane regions, which is of great commercial interest internationally and of local value for rural communities, were defined with the aid of spatial analyses applied to a set of georeferenced molecular marker data (chloroplast and nuclear microsatellites) from 32 populations in 9 African countries. Two approaches for the selection of priority populations for conservation were used, differing in the way they optimize representation of intra-specific diversity of P. africana across a minimum number of populations. The first method (S1) was aimed at maximizing genetic diversity of the conservation units and their distinctiveness with regard to climatic conditions, the second method (S2) at optimizing representativeness of the genetic diversity found throughout the species’ range. Populations in East African countries (especially Kenya and Tanzania) were found to be of great conservation value, as suggested by previous findings. These populations are complemented by those in Madagascar and Cameroon. The combination of the two methods for prioritization led to the identification of a set of 6 priority populations. The potential distribution of P. africana was then modeled based on a dataset of 1,500 georeferenced observations. This enabled an assessment of whether the priority populations identified are exposed to threats from agricultural expansion and climate change, and whether they are located within the boundaries of protected areas. The range of the species has been affected by past climate change and the modeled distribution of P. africana indicates that the species is likely to be negatively affected in future, with an expected decrease in distribution by 2050. Based on these insights, further research at the regional and national scale is recommended, in order to strengthen P. africana conservation efforts. PMID:23544118

    Money is often a limiting factor in conservation, and attempting to conserve endangered species can be costly. Consequently, a framework for optimizing fiscally constrained conservation decisions for a single species is needed. In this paper we find the optimal budget allocation among isolated subpopulations of a threatened species to minimize local extinction probability. We solve the problem using stochastic dynamic programming, derive a useful and simple alternative guideline for allocating funds, and test its performance using forward simulation. The model considers subpopulations that persist in habitat patches of differing quality, which in our model is reflected in different relationships between money invested and extinction risk. We discover that, in most cases, subpopulations that are less efficient to manage should receive more money than those that are more efficient to manage, due to higher investment needed to reduce extinction risk. Our simple investment guideline performs almost as well as the exact optimal strategy. We illustrate our approach with a case study of the management of the Sumatran tiger, Panthera tigris sumatrae, in Kerinci Seblat National Park (KSNP), Indonesia. We find that different budgets should be allocated to the separate tiger subpopulations in KSNP. The subpopulation that is not at risk of extinction does not require any management investment. Based on the combination of risks of extinction and habitat quality, the optimal allocation for these particular tiger subpopulations is an unusual case: subpopulations that occur in higher-quality habitat (more efficient to manage) should receive more funds than the remaining subpopulation that is in lower-quality habitat. Because the yearly budget allocated to the KSNP for tiger conservation is small, to guarantee the persistence of all the subpopulations that are currently under threat we need to prioritize those that are easier to save.

    Although predation bounty programs (rewards offered for capturing or killing an animal) ended more than 40 years ago in Canada, they were reintroduced in Alberta in 2007 by hunting, trapping, and farming organizations, municipalities and counties, and in 2009 in Saskatchewan, by municipal and provincial governments and the Saskatchewan Cattlemen’s Association. Bounty hunters use inhumane and non-selective killing methods such as shooting animals in non-vital regions, and killing neck snares and strychnine poisoning, which cause suffering and delayed deaths. They are unselective, and kill many non-target species, some of them at risk. Predator bounty programs have been found to be ineffective by wildlife professionals, and they use killing methods that cause needless suffering and jeopardize wildlife conservation programs. Our analysis therefore indicates that government agencies should not permit the implementation of bounty programs. Accordingly, they must develop conservation programs that will minimize wildlife-human conflicts, prevent the unnecessary and inhumane killing of animals, and ensure the persistence of all wildlife species.

    Growing concern about the loss of ecosystem services (ES) promotes their spatial representation as a key tool for the internalization of the ES framework into land use policies. Paradoxically, mapping approaches meant to inform policy decisions focus on the magnitude and spatial distribution of the biophysical supply of ES, largely ignoring the social mechanisms by which these services influence human wellbeing. If social mechanisms affecting ES demand, enhancing it or reducing it, are taken more into account, then policies are more effective. By developing and applying a new mapping routine to two distinct socio-ecological systems, we show a strong spatial uncoupling between ES supply and socio-ecological vulnerability to the loss of ES, under scenarios of land use and cover change. Public policies based on ES supply might not only fail at detecting priority conservation areas for the wellbeing of human societies, but may also increase their vulnerability by neglecting areas of currently low, but highly valued ES supply.

    As part of an ongoing effort at Lawrence Livermore National Laboratory (LLNL) to enhance analytical models that simulate enrichment and conversion facilities, efforts are underway to develop routines to estimate the total gamma-ray flux and that of specific lines around process piping containing UF{sub 6}. The intent of the simulation modeling effort is to aid in the identification of possible areas where material diversion could occur, as input to an overall safeguards strategy. The operation of an enrichment facility for the production of low enriched uranium (LEU) presents certain proliferation concerns, including both the possibility of diversion of LEU and the potential for producing material enriched to higher-than-declared, weapons-usable levels. Safeguards applied by the International Atomic Energy Agency (IAEA) are designed to provide assurance against diversion or misuse. Among the measures being considered for use is the measurement of radiation fields at various locations in the cascade hall. Our prior efforts in this area have focused on developing a model to predict neutron fields and how they would change during diversion of misuse. The neutron models indicated that while neutron detection useful in monitoring feed and product containers, it was not useful for monitoring process lines. Our current effort is aimed at developing algorithms that provide estimates of the gamma radiation field outside any process line for the purpose of determining the most effective locations for placing in-plant gamma-monitoring equipment. These algorithms could also be modified to provide both dose and spectral information and, ultimately, detector responses that could be physically measured at various points on the process line. Such information could be used to optimize detector locations in support of real-time on-site monitoring to determine the enrichment levels within a process stream.

    Several studies have shown an increased morphological variability of sloths from mammalian norms, affecting varied phenotypic traits from skeletal parts to soft tissues. We present here the first descriptive comparison of the whole skull morphology within the two extant sloth genera, combining geometric morphometric approaches with comparative anatomy. We used these methods to explore the patterns of the intra- and interspecific morphological variation of the skull with regard to several factors such as phylogeny, geography, allometry, or sexual dimorphism. Our study first revealed strong phylogenetic and geographical imprints on the cranial and mandibular morphological traits. This result demonstrates the importance of accurate knowledge of species and their geographical distributions; here we show from an example pertaining to Bradypus variegatus populations the implications this has on conservation management. Moreover, in order to control the amount of this detected variation, we tentatively compared sloths to a wide range of mammalian species. Our analysis found no significant increase in the average deviation of skull shape within each investigated sloth species compared to other mammals. This suggests that the intraspecific cranial variation in sloths does not depart significantly from the variation observed in other mammals. This result has positive implications for the demarcation of anatomical regions that maintain high levels of morphological variation in sloths.

    Wildlife forensic science is a relatively recent development to meet the increasing need of the criminal justice system where there are investigations in alleged transgressions of either international or national legislation. This application of science draws on conservation genetics and forensic geneticists from mainstream forensic science. This review is a broad overview of the history of forensic wildlife science and some of the recent developments in forensic wildlife genetics with the application of DNA developments to nonhuman samples encountered in a forensic science investigation. The review will move from methods to look at the entire genome, when there is no previous knowledge of the species studied, through methods of species identification, using DNA to determine a possible geographic origin, through to assigning samples to a particular individual or a close genetic relative of this individual. The transfer of research methods into the criminal justice system for the investigation of wildlife crimes has been largely successful as is illustrated in the review. The review concludes with comments on the need for standardization and regulation in wildlife forensic science.

    Growing concern about the loss of ecosystem services (ES) promotes their spatial representation as a key tool for the internalization of the ES framework into land use policies. Paradoxically, mapping approaches meant to inform policy decisions focus on the magnitude and spatial distribution of the biophysical supply of ES, largely ignoring the social mechanisms by which these services influence human wellbeing. If social mechanisms affecting ES demand, enhancing it or reducing it, are taken more into account, then policies are more effective. By developing and applying a new mapping routine to two distinct socio-ecological systems, we show a strong spatial uncoupling between ES supply and socio-ecological vulnerability to the loss of ES, under scenarios of land use and cover change. Public policies based on ES supply might not only fail at detecting priority conservation areas for the wellbeing of human societies, but may also increase their vulnerability by neglecting areas of currently low, but highly valued ES supply.

    Land-use planning using geographic information systems (GIS) commonly emphasizes biophysical spatial data; however planning can be improved by integrating spatial sets of socioeconomic data into the GIS. As an example, we compared a traditional GIS-aided forestry planning protocol that considered only biophysical suitability, with an integrated GIS-aided approach that incorporated both biophysical and socioeconomic suitability. The analyses were conducted for the planning of plantation investments in the Kyaukpadaung Township in the dry zone of central Myanmar. The traditional approach used three biophysical layers for suitability: land use, slope, and accessibility. In contrast, the integrated GIS approach included biophysical suitability data, perceptions and preferences of local villagers towards forestry (social suitability), and quantitative socioeconomic data. The results indicated that the integrated approach provided two principal benefits over the traditional method. First, the integrated method resulted in a more precise idea of suitable sites for plantation investment that could benefit more rural people and also lead to greater investment efficiency. Second, incorporating social preference into the GIS takes into account the crucial element of social capital (viz., social preference), which should lead to higher levels of community acceptance of plantation projects because those plantations would be established on socially suitable land. A second GIS exercise showed how conservation investment decisions could be informed using the integrated method. The results of this study support the idea that GIS-aided planning activities can be enhanced through the incorporation of social data into the analysis. When applicable, spatial data collection efforts for GIS-based planning exercises should incorporate spatial socioeconomic data.

    1. Modern farming practices threaten wildlife in different ways, and failure to identify the complexity of multiple threats acting in synergy may result in ineffective management. To protect ground-nesting birds in farmland, monitoring and mitigating impacts of mechanical harvesting is crucial. 2. Here, we use 6 years of data from a nationwide volunteer-based monitoring scheme of the Montagu's harrier, a ground-nesting raptor, in French farmlands. We assess the effectiveness of alternative nest protection measures and map their potential benefit to the species. 3. We show that unprotected nests in cultivated land are strongly negatively affected by harvesting and thus require active management. Further, we show that protection from harvesting alone (e.g. by leaving a small unharvested buffer around the nest) is impaired by post-harvest predation at nests that become highly conspicuous after harvest. Measures that simultaneously protect from harvesting and predation (by adding a fence around the nest) significantly enhance nest productivity. 4. The map of expected gain from nest protection in relation to available volunteers' workforce pinpoints large areas of high expected gain from nest protection that are not matched by equally high workforce availability. This mismatch suggests that the impact of nest protection can be further improved by increasing volunteer efforts in key areas where they are low relative to the expected gain they could have. 5. Synthesis and applications. This study shows that synergistic interplay of multiple factors (e.g. mechanical harvesting and predation) may completely undermine the success of well-intentioned conservation efforts. However, identifying areas where the greatest expected gains can be achieved relative to effort expended can minimize the risk of wasted volunteer actions. Overall, this study underscores the importance of citizen science for collecting large-scale data useful for producing science and ultimately informs

    The Energy Conservation for New Buildings Act of 1976, as amended, 42 U.S.C Section 6831 et. seq. requires the US Department of Energy to issue energy conservation standards for the design of new residential and commercial buildings. The standards will be mandatory only for the design of new federal buildings, and will serve as voluntary guidelines for the design of new non-federal buildings. This report documents the development and testing of a set of recommendations, from the American Society of Heating, Refrigeration and Air Conditioning Engineers, Inc. (ASHRAE) Special Projects Committee No. 53, designed to provide the technical foundation for the Congressionally-mandated energy standard for new residential buildings. The recommendations have been developed over the past 25 months by a multidisciplinary project team, under the management of the US Department of Energy and its prime contractor, Pacific Northwest Laboratory. Volume III -- Introduction and Background to the Standard Development Effort is a description of the Standard development process and contains the rationale for the general approach and specific criteria contained within the recommendations.

    Throughout the first decade of AIDS, certain populations have been disproportionately affected by its spread, particularly men, blacks, Hispanics, and the young. Just as there are population differences in the spread of the disease, there are differences in knowledge about the disease as well. This article applies the knowledge gap framework to examine the nature and magnitude of gaps in knowledge among different populations. The analysis shows that persons of low education lag behind other groups in true-transmission knowledge (i.e., knowledge about ways in which HIV/AIDS actually is transmitted) and false-transmission knowledge (i.e., misconceptions about how the disease is spread).

    Despite the proven efficacy of decision aids as interventions for increasing patient engagement and facilitating shared decision making, they are not used routinely in clinical care. Findings from a project designed to achieve such integration, conducted at five primary care practices in 2010-12, document low rates of distribution of decision aids to eligible patients due for colorectal cancer screening (9.3 percent) and experiencing back pain (10.7 percent). There were also no lasting increases in distribution rates in response to training sessions and other promotional activities for physicians and clinic staff. The results of focus groups, ethnographic field notes, and surveys suggest that major structural and cultural changes in health care practice and policy are necessary to achieve the levels of use of decision aids and shared decision making in routine practice envisioned in current policy. Among these changes are ongoing incentives for use, physician training, and a team-based practice model in which all care team members bear formal responsibility for the use of decision aids in routine primary care.

    Despite a growing recognition of songs as a useful HIV/AIDS campaign strategy, little research has investigated their potential and/or actual impact. In this study, through a theory-based content analysis, we have assessed the prevention domains covered and the health-relevant constructs promoted by 23 AIDS songs widely used to aid prevention efforts in Ethiopia. To identify the health-relevant constructs and reveal their potential to facilitate or inhibit positive changes, the Extended Parallel Process Model (EPPM) has been used. The findings revealed that the songs cover most of the prevention domains that constitute the current agenda of behavior change communication in Sub-Saharan Africa. However, although all the EPPM variables have been found in almost every song, there were significantly more efficacy messages than threat messages. This suggests that although the songs may lead to positive changes in HIV/AIDS-related outcomes among audiences who have already perceived the threat posed by HIV/AIDS, they are less likely to motivate and thereby generate responses from audiences who have less or no threat perceptions. It is argued that given their potential as a culturally appropriate strategy in Sub-Saharan Africa where oral channels of communication play significant roles, songs could be harnessed for better outcomes through a theory-based design.

    Background To determine policy implications, this analysis tracks the evolution of HIV/AIDS infection across China to understand current trends and potential risk factors. Methods and Principal Findings A retrospective study with spatial analytical model and multilevel spatial models was conducted among 326,157 HIV/AIDS cases reported from 1989–2009. The results indicate that the distribution of HIV/AIDS was clustered at the county level with different directional distributions across China from 2003 to 2009. Compared to 2003, by 2009 there was a 122% increase in HIV cases among rural residents, 294% increase among urban residents, 211% increase among migrants, and 237% increase among permanent residents. The overall proportion of HIV by different routes of transmission showed dramatic changes with a 504% increase in sexual transmission of HIV, 90% decrease in blood/plasma transmission, and 35% decrease in injecting drug user transmission. Sexual transmission was the major transmission route among women (44%) and the elderly (59% in men, 44% in women) as well as among permanent (36%) and urban residents (33%). Among those <65 years old, women increased more than men, but among those ≥65 years, men increased more than women. Migrants contributed to the variance of HIV infection between counties but not within counties. The length of highway and urbanization combined with illiteracy were risk factors for HIV/AIDS. Conclusions/Significance Rates of HIV/AIDS among permanent urban residents, particularly women and elderly men, have increased significantly in recent years. To prevent HIV from spreading further among the general population, additional attention should be paid to these populations as well as to migrants. PMID:21998679

    National political context is widely understood to be an important factor shaping the ecological and socio-economic impacts of protected areas (PAs) and other conservation interventions. Despite broad recognition that national political context matters, however, there is little systematic understanding about how and why it matters, particularly in the context of PAs. This article seeks to advance empirical and theoretical understanding of the influence of national political context on the impacts of conservation interventions through study of an international aid project in a large transboundary PA in West Africa. It uses multilevel regression analysis to analyze the variable effects of changes in enforcement—a central mechanism through which the Protected Ecosystems in Sudano-Sahelian Africa project sought to achieve its objectives—in the W National Parks (WNP) of Benin and Niger. We find that differences in national political context relating to governance quality and extent of democratic decentralization moderated the social-ecological effects of enforcement. Increasing enforcement levels in Benin’s WNP were associated with significant increases in mammal species abundance while having little average effect on the incomes of households around the Park. By contrast, greater levels of enforcement in Niger’s WNP were associated with sharply decreasing income levels among Park neighbors but did not have a statistically significant effect on wildlife populations. These results highlight the importance of national political context to the outcomes of aid-funded conservation efforts. They suggest that state-led PA enforcement will have more positive social-ecological impacts in better-governed, more decentralized countries and that conservation policy centered on PAs should therefore devote greater attention to engagement with higher levels of governance.

    Forage quality and availability, climatic factors, and a wetland's conservation status are expected to affect the densities of wetland birds. However, the conservation effectiveness is often poorly studied. Here, using twelve years' census data collected from 78 wetlands in the Yangtze River floodplain, we aimed to understand the effect of these variables on five Anatidae species, and evaluate the effectiveness of the conservation measures by comparing population trends of these species among wetlands that differ in conservations status. We showed that the slope angle of a wetland and the variation thereof best explain the differences in densities of four species. We also found that the population abundances of the Anatidae species generally declined in wetlands along the Yangtze River floodplain over time, with a steeper decline in wetlands with a lower protection status, indicating that current conservation policies might deliver benefits for wintering Anatidae species in China, as population sizes of the species were buffered to some extent against decline in numbers in wetlands with a higher level protection status. We recommend several protection measures to stop the decline of these Anatidae species in wetlands along the Yangtze River floodplain, which are of great importance for the East Asian-Australasian Flyway.

    Camera traps — remotely activated cameras with infrared sensors — first gained measurable popularity in wildlife conservation in the early 1990s. Today, they’re used for a variety of activities, from species-specific research to broad-scale inventory or monitoring programs that, in some cases, attempt to detect biodiversity across vast landscapes. As this modern tool continues to evolve, it’s worth examining its uses and benefits for wildlife management and conservation.

    2016-07-01

    The Nimba Mountains are a West African Natural World Heritage site located in the range of the Guineo-equatorial evergreen rainforest, renowned for its rich biodiversity with a high level of endemism. In 1976, Yukimaru Sugiyama from Kyoto University initiated the long-term study of chimpanzees at Bossou, a Guinean village situated 5 km from the northern foothills of Nimba. This Japanese initiative has provided key discoveries and insights on our closest living evolutionary relatives over the 40 past years, and has grown to become an international collaboration with a research focus extended to adjacent chimpanzee communities. The present paper describes a mid-term behavioral and ecological study on wild chimpanzees populating the southern slope of the Nimba Mountains, conducted in the framework of this collaborative project. It aimed to assess the status and ecological requirements of chimpanzees in order to formulate purpose-built actions for their conservation. We estimated a density of 0.46 chimpanzee per km(2) using nest count methods from line transects. We used logistic and Poisson regressions to investigate basic ecological characteristics of chimpanzees in relation to habitat composition and structure, topography and seasonality. We performed an in-depth analysis of their nesting and feeding behaviors, and identified important components of their diet; we also recorded their year-round ranging patterns. Our findings highlight the importance of old secondary forest and high-altitude habitats for these chimpanzees. We discuss the results in the light of other studies from the perspective of the conservation of the species and its natural habitat.

    Fishery Management Council (SAFMC), which led to the designation of some of these areas as HAPCs or marine protected areas, restricting bottom trawling, longlines and traps that could be destructive to the fragile coral and sponge habitat. In 2010, NOAA established five deep-water Coral HAPCs encompassing a total area of 62,714 km2 from North Carolina to south Florida; an estimated 69% of the total area of the CHAPCs is off Florida. However, we estimate that ~6,554 km2 (29.7%) of DSCE habitat remains unprotected and outside the boundaries of the CHAPCs in U.S. waters off Florida. Many activities may impact DCSEs, including bottom trawling, energy production, and even global warming. Cuba has recently opened its north slope for deep-sea oil/gas drilling, which could have serious impacts upon both deep and shallow water reefs and coastal areas of the U.S. upstream of these drilling sites. Baseline data is critical to understanding the effects of these anthropogenic activities son DSCEs. High-resolution sonar surveys combined with visual ground-truthing to create deep-water benthic habitat maps are necessary to further define the extent of DSCEs in order to protect and conserve these critical habitats.

    Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world's sharks and rays are threatened with extinction. At a regional scale this negative trend has also been evidenced in the central Mediterranean Sea, where bottom-trawl fisheries have affected the biomass of certain rays (e.g. Raja clavata) and sharks (e.g. Mustelus spp.). Detailed knowledge of elasmobranch habitat requirements is essential for biodiversity conservation and fisheries management, but this is often hampered by a poor understanding of their spatial ecology. Habitat suitability models were used to investigate the habitat preference of nine elasmobranch species and their overall diversity (number of species) in relation to five environmental predictors (i.e. depth, sea surface temperature, surface salinity, slope and rugosity) in the central Mediterranean Sea. Results showed that depth, seafloor morphology and sea surface temperature were the main drivers for elasmobranch habitat suitability. Predictive distribution maps revealed different species-specific patterns of suitable habitat while high assemblage diversity was predicted in deeper offshore waters (400-800 m depth). This study helps to identify priority conservation areas and diversity hot-spots for rare and endangered elasmobranchs in the Mediterranean Sea.

Results showed that depth, seafloor morphology and sea surface temperature were the main drivers for elasmobranch habitat suitability. Predictive distribution maps revealed different species-specific patterns of suitable habitat while high assemblage diversity was predicted in deeper offshore waters (400-800 m depth). This study helps to identify priority conservation areas and diversity hot-spots for rare and endangered elasmobranchs in the Mediterranean Sea.

    Commercial fisheries have dramatically impacted elasmobranch populations worldwide. With high capture and bycatch rates, the abundance of many species is rapidly declining and around a quarter of the world's sharks and rays are threatened with extinction. At a regional scale this negative trend has also been evidenced in the central Mediterranean Sea, where bottom-trawl fisheries have affected the biomass of certain rays (e.g. Raja clavata) and sharks (e.g. Mustelus spp.).

    Religious and secular institutions advocate strategies that represent all points on the continuum to reduce the spread of HIV/AIDS. Drawing on an extensive literature review of studies conducted in sub-Saharan Africa, we focus on those secular institutions that support all effective methods of reducing HIV/AIDS transmission and those conservative religious institutions that support a limited set of prevention methods. We conclude by identifying topics for dialogue between these viewpoints that should facilitate cooperation by expanding the generally acceptable HIV/AIDS prevention methods, and especially the use of condoms.

    Wild crop relatives are an important source of genetic variation for improving domesticated species. Given limited resources, methods for maximizing the genetic diversity of collections of wild relatives are needed to help spread protection over a larger number of populations and species. Simulations were conducted to investigate the optimal strategy of sampling materials from populations of wild relatives, with the objective of maximizing the number of alleles (allelic richness) in collections of fixed size. Two methods, based on assessing populations for variation at marker loci (e.g., allozymes, restriction fragment length polymorphisms), were developed and compared with several methods that are not dependent on markers. Marker-assisted methods yielded higher overall allelic richness in the simulated collections, and they were particularly effective in conserving geographically localized alleles, the class of alleles that is most subject to loss.

    This project addresses existing habitat conditions, fish population status, and restoration priority sites within the Rattlesnake Creek watershed, a sub-basin of the White Salmon River. Our partners in this project are the United States Geological Service (USGS), and the Yakama Indian Nation (YIN). Underwood Conservation District (UCD) is involved in the project via accomplishment of water quality monitoring, sampling for stable isotopes, and characterization of the watershed geomorphology. These work items are part of an effort to characterize the stream and riparian habitat conditions in Rattlesnake Creek, to help guide habitat and fish restoration work. Water chemistry and temperature information is being collected both on Rattlesnake Creek, and on other tributaries and the main stem of the White Salmon River. Information on the entire system enables us to compare results obtained from Rattlesnake Creek with the rest of the White Salmon system. Water chemistry and temperature data have been collected in a manner that is comparable with data gathered in previous years. The results from data gathered in the 2001-2002 performance period are reported in appendix A at the end of this 2002-2003 report. Additional work being conducted as part of this study includes; an estimate of salmonid population abundance (YIN and USGS); a determination of fish species composition, distribution, and life history (YIN and USGS), and a determination of existing kinds, distribution, and severity of fish diseases (YIN and USGS). The overall objective is to utilize the above information to prioritize restoration efforts in Rattlesnake Creek.

    Mapping the DNA-binding preferences of transcription factor (TF) complexes is critical for deciphering the functions of cis-regulatory elements. Here, we developed a computational method that compares co-occurring motif spacings in conserved versus unconserved regions of the human genome to detect evolutionarily constrained binding sites of rigid TF complexes. Structural data were used to estimate TF complex physical plausibility, explore overlapping motif arrangements seldom tackled by non-structure-aware methods, and generate and analyse three-dimensional models of the predicted complexes bound to DNA. Using this approach, we predicted 422 physically realistic TF complex motifs at 18% false discovery rate, the majority of which (326, 77%) contain some sequence overlap between binding sites. The set of mostly novel complexes is enriched in known composite motifs, predictive of binding site configurations in TF-TF-DNA crystal structures, and supported by ChIP-seq datasets. Structural modelling revealed three cooperativity mechanisms: direct protein-protein interactions, potentially indirect interactions and 'through-DNA' interactions. Indeed, 38% of the predicted complexes were found to contain four or more bases in which TF pairs appear to synergize through overlapping binding to the same DNA base pairs in opposite grooves or strands. Our TF complex and associated binding site predictions are available as a web resource at http://bejerano.stanford.edu/complex.

    Black/African American and Latino communities are disproportionately affected by the domestic HIV/AIDS epidemic. Blacks/African Americans and Latinos are also more likely to report a formal, religious, or faith affiliation when compared with non-Hispanic whites. As such, faith leaders and their institutions have been identified in the National HIV/AIDS Strategy as having a vital role to serve in reducing: (1) HIV-related health disparities and (2) the number of new HIV infections by promoting non-judgmental support for persons living with and at risk for HIV/AIDS and by serving as trusted information resources for their congregants and communities. We describe faith doctrines and faith-science partnerships that are increasing in support of faith-based HIV prevention and service delivery activities and discuss the vital role of these faith-based efforts in highly affected black/African American and Latino communities.

    The White Salmon River Watershed Enhancement Project (WSRWEP) began in 1993 through efforts of the Underwood Conservation District (UCD), local stakeholders and various agencies. Early accomplishments of the project included the formation of a multi-stakeholder watershed management committee (WMC) and technical advisory committee (TAC), completion of several baseline assessments, drafting of a watershed management plan, and beginning implementation of the plan. Since inception, the effort has utilized the support of various government/private grants, and local in-kind contributions to accomplish project goals. The WMC and its partners utilize a four-pronged approach for achieving watershed enhancement: on-ground restoration, extension of technical and financial assistance to cooperators, community and environmental education, and assessment/monitoring to develop strategies and track the success of ongoing work. Project activities are generally targeted to sub-basins and stream reaches within the White Salmon watershed that exhibit important water quality and fish/wildlife habitat problems. Such project prioritization is being conducted with the active input of both the White Salmon WMC and TAC. An important current phase of the WSRWEP targets detailed monitoring and assessment of the Rattlesnake Creek sub-basin, and is the focus of this report. The 'Assessment of Rattlesnake Creek in Relation to Restoration Efforts' project (BPA Project ID Number 21009) was identified and prioritized for accomplishment by the White Salmon River TAC in January of 2000. Rationale for the project stemmed from the group's realization that Condit Dam on the lower White Salmon is scheduled for removal, or fish passage retrofitting, within the near future. Given this eventuality, the TAC identified the current lack of understanding regarding both potential anadromous habitat and existing native fish and habitat conditions above Condit Dam (RM 3.2) as an important need.

  12. Alanine-scanning mutagenesis defines a conserved energetic hotspot in the CaVα1 AID-CaVβ interaction site that is critical for channel modulation

    2011-01-01

    Voltage-gated calcium channels (CaVs) are large, multisubunit complexes that control cellular calcium entry. CaV pore-forming (CaVα1) and cytoplasmic (CaVβ) subunits associate through a high-affinity interaction between the CaVα1 α-interaction domain (AID) and CaVβ α-binding pocket (ABP). Here, we analyze AID-ABP interaction thermodynamics using isothermal titration calorimetry (ITC). We find that commensurate with their strong sequence similarity, all CaV1 and CaV2 AID peptides bind CaVβ with similar nanomolar affinities. Although the AID-ABP interface encompasses twenty-four sidechains, alanine-scanning mutagenesis reveals that the binding energy is focused in two complementary hotspots comprising four deeply-conserved residues. Electrophysiological experiments show that hotspot interaction disruption prevents trafficking and functional modulation of CaV1.2 by CaVβ. Together, the data support the primacy of the AID-ABP interface for CaVα1-CaVβ association, underscore the idea that hotspots dominate protein-protein interaction affinities, and uncover a target for strategies to control cellular excitability by blocking CaVα1-CaVβ complex formation.

    Conservationists and agriculturists face unprecedented challenges trying to minimize tradeoffs between increasing demands for food, fiber, feed, and biofuels and the resulting loss or reduced values of other ecosystem services, such as those derived from wetlands and biodiversity (Millenium Ecosystem Assessment 2005a, 2005c; Maresch et al. 2008). The Food, Conservation, and Energy Act of 2008 (Pub. L. 110-234, Stat. 923, HR 2419, also known as the 2008 Farm Bill) reauthorized the USDA to provide financial incentives for agricultural producers to reduce environmental impacts via multiple conservation programs. Two prominent programs, the Wetlands Reserve Program (WRP) and the Conservation Reserve Program (CRP), provide incentives for producers to retire environmentally sensitive croplands, minimize erosion, improve water quality, restore wetlands, and provide wildlife habitat (USDA FSA 2008a, 2008b; USDA NRCS 2002). Other conservation programs (e.g., Environmental Quality Incentives Program, Conservation Stewardship Program) provide incentives to implement structural and cultural conservation practices to improve the environmental performance of working agricultural lands. Through its Conservation Effects Assessment Project, USDA is supporting evaluation of the environmental benefits obtained from the public investment in conservation programs and practices to inform decisions on where further investments are warranted (Duriancik et al. 2008; Zinn 1997).

    Endemic to Oregon in the northwestern US, the Oregon slender salamander (Batrachoseps wrighti) is a terrestrial plethodontid found associated with late successional mesic forests. Consequently, forest management practices such as timber harvesting may impact their persistence. Therefore, to infer possible future effects of these practices on population structure and differentiation, we used mitochondrial DNA sequences (cytochrome b) and RAPD markers to analyze 22 populations across their range. Phylogenetic analyses of sequence data (774 bp) revealed two historical lineages corresponding to northern and southern-distributed populations. Relationships among haplotypes and haplotype diversity within lineages suggested that the northern region may have more recently been colonized compared to the southern region. In contrast to the mitochondrial data, analyses of 46 RAPD loci suggested an overall pattern of isolation-by-distance in the set of populations examined and no particularly strong clustering of populations based on genetic distances. We propose two non-exclusive hypotheses to account for discrepancies between mitochondrial and nuclear data sets. First, our data may reflect an overall ancestral pattern of isolation-by-distance that has subsequently been influenced by vicariance. Alternately, our analyses may suggest that male-mediated gene flow and female philopatry are important contributors to the pattern of genetic diversity. We discuss the importance of distinguishing between these two hypotheses for the purposes of identifying conservation units and note that, regardless of the relative contribution of each mechanism towards the observed pattern of diversity, protection of habitat will likely prove critical for the long-term persistence of this species.

    Recent exploratory research along the Atlantic coast of the US has demonstrated the utility of dual autonomous underwater vehicle (AUV) systems for side-scan surveys, multibeam mapping, and photo-imaging of deep-water habitat and octocoral gardens. The potential of the REMUS 6000 AUVs was demonstrated by mapping high-relief coral mounds in the Straits of Florida in the strong currents of the Gulf Stream, and the submarine canyons and seamounts off the Northeastern US coast. The key to protecting these slow-growing deep coral reefs and critical hard-bottom habitat is the ability to efficiently discover and map their locations, characterize their structure, and assess their condition. Data from these deepwater AUV surveys were used to inform the regional fishery management councils and NOAA NMFS for the management and potential protection of these vulnerable habitats. These projects were realized though the collaborative efforts of the Waitt Institute, Woods Hole Oceanographic Institution, Harbor Branch Oceanographic Institute, NOAA National Marine Fisheries Service, the Natural Resource Defense Council, and the University of Connecticut.

    1998-01-01

    Recent advances in molecular technology have opened a new chapter in species conservation efforts, as well as population biology. DNA sequencing, MHC (major histocompatibility complex), minisatellite, microsatellite, and RAPD (random amplified polymorphic DNA) procedures allow for identification of parentage, more distant relatives, founders to new populations, unidentified individuals, population structure, effective population size, population-specific markers, etc. PCR (polymerase chain reaction) amplification of mitochondrial DNA, nuclear DNA, ribosomal DNA, chloroplast DNA, and other systems provide for more sophisticated analyses of metapopulation structure, hybridization events, and delineation of species, subspecies, and races, all of which aid in setting species recovery priorities. Each technique can be powerful in its own right but is most credible when used in conjunction with other molecular techniques and, most importantly, with ecological and demographic data collected from the field. Surprisingly few taxa of concern have been assayed with any molecular technique. Thus, rather than showcasing exhaustive details from a few well-known examples, this paper attempts to present a broad range of cases in which molecular techniques have been used to provide insight into conservation efforts.

    The National AIDS Convention in South Africa (NACOSA) in October 1992 was the first real attempt to address HIV/AIDS. In Soweto, government, the African National Congress, nongovernmental organizations, and organized industry and labor representatives worked for 2 days to develop a national plan of action, but it did not result in a united effort to fight AIDS. The highest HIV infection rates in South Africa are among the KwaZulu in Natal, yet the Inkatha Freedom Party did not attend NACOSA. This episode exemplifies the key obstacles for South Africa to prevent and control AIDS. Inequality of access to health care may explain why health workers did not diagnose the first AIDS case in blacks until 1985. Migrant labor, Bantu education, and uprooted communities affect the epidemiology of HIV infection. Further, political and social polarization between blacks and whites contributes to a mindset that AIDS is limited to the other race which only diminishes the personal and collective sense of susceptibility and the volition and aptitude to act. The Department of National Health and Population Development's voluntary register of anonymously reported cases of AIDS specifies 1517 cumulative AIDS cases (October 1992), but this number is low. Seroprevalence studies show between 400,000-450,000 HIV positive cases. Public hospitals cannot give AIDS patients AZT and DDI. Few communities provided community-based care. Not all hospitals honor confidentiality and patients' need for autonomy. Even though HIV testing is not mandatory, it is required sometimes, e.g., HIV testing of immigrants. AIDS Training, Information and Counselling Centers are in urban areas, but not in poor areas where the need is most acute. The government just recently developed in AIDS education package for schools, but too many people consider it improper, so it is not being used. The poor quality education provided blacks would make it useless anyhow. Lifting of the academic boycott will allow South African

    The World Health Organization (WHO) estimates that some 300,000 AIDS cases will be diagnosed by the end of 1988. As of December 1987, 128 countries had reported a total of 72,000 cases, about half the number of cases that actually occurred. The WHO estimates that some 5-10 million persons are already infected with HIV, so that the number of AIDS cases will increase rapidly for the next 5 years at least. The number of cases reported in Africa increased considerably in 1987, reflecting greater awareness of AIDS and greater efforts at control. By late 1987 WHO was working actively with over 100 countries to combat AIDS. An expert meeting organized by the WHO Special Program to Combat AIDS recommended to governments and prison administrators that condoms be provided to inmates and that treatment programs be provided for intravenous drug addicts. Prison personnel should receive education about HIV infection and AIDS. Incarceration policies, especially for drug addicts, should be reviewed in light of the AIDS epidemic. An estimated average of 10% of the 270,000 prisoners enumerated in 17 European countries are believed to be HIV positive, but the proportion increases to 26% in the highest risk countries. The proportion of seropositive subjects in general exceeds that in the total population.

    The first people to be infected with HIV in Malaysia were mainly homosexual men with foreign connections. IV drug users, however, rapidly became the population group with the highest prevalence of HIV. Accurate, timely data are needed in order to responsibly describe the pattern of HIV infection and AIDS in any given setting. In Malaysia, however, there has been little systematic surveillance in population groups other than blood donors. This surveillance indicates the existence of a rapidly increasing rate of seropositivity among blood donors. Otherwise, many people are loathe to undergo voluntary HIV testing to determine their serostatus. Moreover, some people with STDs avoid contact with the health system and the potential for HIV testing. The extent to which AIDS cases are underreported or reported late is unknown. On the other hand, an estimated 10% of notified AIDS cases have been wrongly classified as such. The lack of hard data on HIV/AIDS in Malaysia makes it difficult to project the future course of the epidemic in the country. Since Malaysia shares a land border with Thailand and there is much sea-borne traffic between the two countries, it is highly possible that Malaysia will experience a significant epidemic of HIV infection similar to its neighbors. A National AIDS Committee was established April 1985 to develop responses to the HIV epidemic, while the National AIDS Program Manager of the Ministry of Health is responsible for controlling STDs. A national plan of action for the prevention and control of AIDS, drawn up in 1985 and revised in 1988, includes planning for the continued surveillance of HIV infection and AIDS through existing notification systems, and for screening and sentinel programs for IV drug users, prostitutes, and STD patients. Recent nongovernmental organization responses complement government efforts to prevent HIV and AIDS in Malaysia. PMID:7857575

    An 86-year-old man presented ambulatory with acute dysphagia. Radiologic examination and endoscopy revealed a swallowed postauricular hearing aid. The earmold of the hearing aid became visible in the hypopharynx after mucus and saliva were removed. It could be extracted without effort once the connecting tube was disconnected from the coupling device lodged in the upper esophageal sphincter. The hearing aid itself was impacted in the proximal esophagus and was extracted without any problems. The postoperative phase was uneventful with normal swallowing and discharge. Technical inspection revealed that the hearing aid no longer worked. Diffusion of toxic substances (zinc, mercury) from the impacted batteries is not to be expected.

  2. Ergogenic aids.

    The catabolism of bodily fuels provides the energy for muscular work. Work output can be limited by the size of fuel reserves, the rate of their catabolism, the build-up of by-products, or the neurologic activation of muscle. A substance that favorably affects a step that is normally limiting, and thus increases work output, can be considered an ergogenic aid. The maximal amount of muscular force generated during brief contractions can be acutely increased during hypnosis and with the ingestion of a placebo or psychomotor stimulant. This effect is most obvious in subjects under laboratory conditions and is less evident in athletes who are highly motivated prior to competition. Fatigue is associated with acidosis in the working musculature when attempts are made to maximize work output during a 4 to 15-minute period. Sodium bicarbonate ingestion may act to buffer the acid produced, provided that blood flow to the muscle is adequate. Prolonged intense exercise can be maintained for approximately two hours before carbohydrate stores become depleted. Carbohydrate feedings delay fatigue during prolonged exercise, especially in subjects who display a decline in blood glucose during exercise in the fasting state. Caffeine ingestion prior to an endurance bout has been reported to allow an individual to exercise somewhat more intensely than he or she would otherwise. Its effect may be mediated by augmenting fat metabolism or by altering the perception of effort. Amphetamines may act in a similar manner. Water ingestion during prolonged exercise that results in dehydration and hyperthermia can offset fluid losses and allow an individual to better maintain work output while substantially reducing the risk of heat-related injuries.

The efforts are related to small business (SBIR, STTR) contracts, academic research grants (MURI), and contracts awarded as the result of specialized solicitations. This paper covers a number of Army potential uses of the TPV power generation and is an attempt to give a more cohesive and integrated picture of the various military interests in TPV. With the exception of low power (<10 W) units, all Army potential uses of TPV power sources will demand operation with logistically available fuels.

    Systematic conservation planning optimizes trade-offs between biodiversity conservation and human activities by accounting for socioeconomic costs while aiming to achieve prescribed conservation objectives. However, the most cost-efficient conservation plan can be very dissimilar to any other plan achieving the set of conservation objectives. This is problematic under conditions of implementation uncertainty (e.g., if all or part of the plan becomes unattainable). We determined through simulations of parallel implementation of conservation plans and habitat loss the conditions under which optimal plans have limited chances of implementation and where implementation attempts would fail to meet objectives. We then devised a new, flexible method for identifying conservation priorities and scheduling conservation actions. This method entails generating a number of alternative plans, calculating the similarity in site composition among all plans, and selecting the plan with the highest density of neighboring plans in similarity space. We compared our method with the classic method that maximizes cost efficiency with synthetic and real data sets. When implementation was uncertain--a common reality--our method provided higher likelihood of achieving conservation targets. We found that χ, a measure of the shortfall in objectives achieved by a conservation plan if the plan could not be implemented entirely, was the main factor determining the relative performance of a flexibility enhanced approach to conservation prioritization. Our findings should help planning authorities prioritize conservation efforts in the face of uncertainty about future condition and availability of sites.

    Identification of biodiversity hotspots (hereafter, hotspots) has become a common strategy to delineate important areas for wildlife conservation. However, the use of hotspots has not often incorporated important habitat types, ecosystem services, anthropogenic activity, or consistency in identifying important conservation areas. The purpose of this study was to identify hotspots to improve avian conservation efforts for Species of Greatest Conservation Need (SGCN) in the state of Idaho, United States. We evaluated multiple approaches to define hotspots and used a unique approach based on weighting species by their distribution size and conservation status to identify hotspot areas. All hotspot approaches identified bodies of water (Bear Lake, Grays Lake, and American Falls Reservoir) as important hotspots for Idaho avian SGCN, but we found that the weighted approach produced more congruent hotspot areas when compared to other hotspot approaches. To incorporate anthropogenic activity into hotspot analysis, we grouped species based on their sensitivity to specific human threats (i.e., urban development, agriculture, fire suppression, grazing, roads, and logging) and identified ecological sections within Idaho that may require specific conservation actions to address these human threats using the weighted approach. The Snake River Basalts and Overthrust Mountains ecological sections were important areas for potential implementation of conservation actions to conserve biodiversity. Our approach to identifying hotspots may be useful as part of a larger conservation strategy to aid land managers or local governments in applying conservation actions on the ground.

    This article discusses the acquired immunodeficiency syndrome (AIDS) epidemic an its effect on developing countries, with emphasis on Africa. The AIDS death toll will be high in the US: 180,000 by 1991, but it will be in the millions in developing countries. In Africa, AIDS is mainly transmitted heterosexually, is as prevalent among women as among men, and is taking a serious toll among professional classes and young wage earners. The social costs of funerals has increased, and company clinics and sick pay funds have been overwhelmed. In Uganda, the epidemic adds to the state of psychological shock people have sufferred because of the civil war. Medical professionals have been hard-pressed to acquire equipment for testing blood for the virus, although there have been efforts to protect blood supplies through exhaustive testing. Endemic tuberculosis becomes an even more serious problem in developing countries, since AIDS lowers resistance to it. AIDS also effects many developing country children, usually through infected mothers, who can transmit AIDS through breast milk or during pregnancy of birth. This poses a dilemma for promoters of breastfeeding. It is also feared that innoculation of immunosuppressed children may be dangerous. The global picture suggests that Africa is hardest hit: seropositivity prevalence ranges from 0.7% of Congo blood donors to 33% of male donors in Lusaka Zambia. Brazil's cases are mainly homosexual, and in Asia the prevalence is mostly low, although there is a great potential danger in countries where prostitution and heroin addiction are prevalent. The only effective weapon against AIDS is education and blood testing to prevent spread. Despite good education programs in some countries, e.g. Rwanda, there is still widespread ignorance of how AIDS is spread. PMID:12314457

    Both the new high temperature superconductors (HTS) and the low temperature superconductors (LTS) are important components of Navy's total plan to integrate superconductivity into field operational systems. Fundamental research is an important component of the total Navy program and focuses on the HTS materials. Power applications (ship propulsion, etc.) use LTS materials while space applications (MMW electronics, etc.) use HTS materials. The Space Experiment being conducted at NRL will involve space flight testing of HTS devices built by industry and will demonstrate the ability to engineer and space qualify these devices for systems use. Another important component of the Navy's effort is the development of Superconducting Quantum Interference Device (SQUID) magnetometers. This program will use LTS materials initially, but plans to implement HTS materials as soon as possible. Hybrid HTS/LTS systems are probable in many applications. A review of the status of the Navy's HTS materials research is given as well as an update on the Navy's development efforts in superconductivity, with particular emphasis on the related SDIO sponsored program on HTS applications.

    This past summer. our small field team followed a 4000 km route through central and eastern Mongolia. Even though there was a population crash underway for picas (Ochotona sp.) and voles (Microtus sp.). we found 38 new saker nests and visited 60 eyries found in previous years. Many of the former eyries were unoccupied. Others were occupied but without young. Productivity was good at eyries with large young. and southeastern Mongolia seemed unaffected by food shortages. The main goal for 1997 was to create new eyries and enlarge. stabilise. or otherwise alter marginal eyries. \\Ve created 65 eyries as follows: 8 on wooden powerlines or telephone supports, 8 on metal power line towers, 3 in trees, 3 on boulders, 11 on cliffs, 17 on abandoned buildings, 9 on metal geological survey towers, and 6 on miscellaneous structures. \\Ve also enlarged or repaired three establishedeyries and did minor repairs on several others. Lesser accomplishments include what may be the first observation of siblicide for the saker falcon (please contact us immediately if you have other records of sakerchicks attacking or killing their nest mates) and the description of a new saker flight display. We also documented an unusual golden eagle eyrie containing the remains of nearly 30 foxes, several predatory birds, and a number of gazelle. In 1998. we plan to return to Mongolia to see how many of our 'fake eyries' attracted falcons. Our work in 1997 was supported by Mr. Howell. another philanthropist (anonymous) and the Institute of Raptor Studies.

    Most of the 36 species of wild cats are classified as threatened, vulnerable or endangered due to poaching and habitat loss. The important role of assisted reproduction techniques (ART) as part of a multifaceted captive breeding program for selected wild cat species is gradually gaining acceptance. This recognition is a result of the progress made during the last decade in which the feasibility of oocyte recovery from gonadotropin-treated females, in vitro fertilization, embryo cryopreservation and embryo transfer (ET) was demonstrated in the domestic cat (Felis catus). Additionally, embryos have been produced in vitro from oocytes matured in vitro after recovery from ex situ ovaries of both domestic and non-domestic cat species and domestic kittens have been born following transfer of these embryos. In vitro fertilization has been successful in at least one-third of wild cat species and kittens were born after transfer of Indian desert cat (Felis sylvestris ornata) embryos into a domestic cat and con-specific transfer of tiger (Panthera tigris) embryos. The domestic cat is not only a valuable model for development of in vitro techniques but may serve as a recipient of embryos from several species of small wild cats. PMID:10735071

    A generic framework for setting conservation priorities based on the principles of classic decision theory is provided. This framework encapsulates the key elements of any problem, including the objective, the constraints, and knowledge of the system. Within the context of this framework the broad array of approaches for setting conservation priorities are reviewed. While some approaches prioritize assets or locations for conservation investment, it is concluded here that prioritization is incomplete without consideration of the conservation actions required to conserve the assets at particular locations. The challenges associated with prioritizing investments through time in the face of threats (and also spatially and temporally heterogeneous costs) can be aided by proper problem definition. Using the authors' general framework for setting conservation priorities, multiple criteria can be rationally integrated and where, how, and when to invest conservation resources can be scheduled. Trade-offs are unavoidable in priority setting when there are multiple considerations, and budgets are almost always finite. The authors discuss how trade-offs, risks, uncertainty, feedbacks, and learning can be explicitly evaluated within their generic framework for setting conservation priorities. Finally, they suggest ways that current priority-setting approaches may be improved.

    On 15 October 1997 at 4:43 AM EDT, the Cassini spacecraft was successfully launched on a Titan IVB/Centaur on a mission to explore the Saturnian system. It carried three Radioisotope Thermoelectric Generators (RTGs) and 117 Light Weight Radioisotope Heater Units (LWRHUs). As part of the joint National Aeronautics and Space Administration (NASA)/U.S. Department of Energy (DoE) safety effort, a contingency plan was prepared to address the unlikely events of an accidental suborbital reentry or out-of-orbital reentry. The objective of the plan was to develop procedures to predict, within hours, the Earth impact footprints (EIFs) for the nuclear heat sources released during the atmospheric reentry. The footprint predictions would be used in subsequent notification and recovery efforts. As part of a multi-agency team, The Johns Hopkins University Applied Physics Laboratory (JHU/APL) had the responsibility to predict the EIFs of the heat sources after a reentry, given the heat sources' release conditions from the main spacecraft. (No ablation burn-through of the heat sources' aeroshells was expected, as a result of earlier testing.) JHU/APL's other role was to predict the time of reentry from a potential orbital decay. The tools used were a three degree-of-freedom trajectory code, a database of aerodynamic coefficients for the heat sources, secure links to obtain tracking data, and a high fidelity special perturbation orbit integrator code to predict time of spacecraft reentry from orbital decay. In the weeks and days prior to launch, all the codes and procedures were exercised. Notional EIFs were derived from hypothetical reentry conditions. EIFs predicted by JHU/APL were compared to those by JPL and US SPACECOM, and were found to be in good agreement. The reentry time from orbital decay for a booster rocket for the Russian Progress M-36 freighter, a cargo ship for the Mir space station, was predicted to within 5 minutes more than two hours before reentry.

    Chronically immunosuppressed individuals are susceptible to lymphoreticular tumors. Up to 15% of patients with congenital deficiencies such as ataxia=telangiectasia may develop malignancies, mainly high-grade B cell non=Hodgkin's lymphomas (NHLs). AIDS lymphomas are comprised of NHLs including Burkitt's lymphoma (BL) and primary cerebral lymphomas (PCLs). Almost 3% of all AIDS patients (2824 of 97,258 cases) developed NHL. Epstein-Barr virus (EBV) as a co-factor in AIDS lymphomagenesis has been studied: in 12 cases of 24 AIDS lymphomas EBV by DNA in situ hybridization was found. In an analysis of 6 primary cerebral lymphomas, .5 were positive for EBV DNA by Southern blotting. In Burkitt's lymphoma the characteristic genetic alteration affects the c-myc oncogene. In 1/3 of BL p53 mutations were found but none in the 43 NHLs suggesting that p53 mutations and c-myc activation act synergistically in the pathogenesis of these tumors. Cytotoxic agents dideoxyinosine, dideoxycytosine, and zidovudine may cause secondary neoplasia. 8 of 55 AIDS patients under zidovudine treatment developed high-grade lymphoma 23.8 months subsequently; recently doses were reduced. PCL was found in 21 of 90 patients. A 5.2 months survival was associated with combined treatment with cyclophosphamide, Oncovin (vincristine), methotrexate, etoposide, and cytosine arabinoside compared with 11.3 months with chemotherapy. Colony-stimulating factors (CSFs) alleviate drug-induced myelotoxicity and zidovudine-induced neutropenia, however, l8 of 11 patients receiving granulocyte-macrophage CSF developed hematological toxicity. Interleukine-2 produced by T-helper cells enhancing tumor cells cytotoxicity has been used in AIDS-associated cryptosporidial diarrhea and in 4 patients with AIDS lymphoma with modest response, but its stimulation of the HIV-infected substrate may increase viral proliferation.

    By 2020, HIV/AIDS will be the leading infectious killer of young and middle-aged adults in the developing world. Past gains in life expectancy are already being eroded in some countries. Millions of lives can, however, be saved if developing country governments, the international community, and nongovernmental organizations act now. Although more than 11 million people have already died of AIDS, 2.3 billion people live in developing countries in which the disease has not yet spread beyond certain risk groups. If the spread of HIV is checked, the quality of care available to people who are infected with HIV will probably be better than it would be in the context of a full-blown AIDS epidemic. However, while governments need to respond urgently to HIV/AIDS, using resources to help people with AIDS will reduce the resources available for other investments, such as child education, providing safe drinking water, and building roads. Economics can help governments set priorities as they decide how best to allocate their available resources. Externalities, public goods, and redistribution are discussed. All countries will need to use some combination of preventive and coping measures. PMID:12293445

    2009-04-01

    Although the application of population and evolutionary genetic theory and methods to address issues of conservation relevance has a long history, the formalization of conservation genetics as a research field is still relatively recent. One of the periodic catalysts for increased research effort in the field has been advances in molecular technologies, leading to an increasingly wider variety of molecular markers for application in conservation genetic studies. To date, genetic methods have been applied in conservation biology primarily as selectively neutral molecular tools for resolving questions of conservation relevance. However, there has been renewed interest in complementing the analysis of neutral markers with the assessment of loci that may be directly involved in responses to processes such as environmental change, with a view to identifying the genes involved in them. These kinds of studies are now possible due to the increase in availability of genomic resources for nonmodel organisms, and there will likely be an even more rapid increase in the near future due to the advent of new ultrahigh throughput-sequencing technologies. This review considers the implications of the most recent developments in genomic technologies and their potential for contributing to the conservation of populations and species. Three "conservation genomics" case studies are presented (Atlantic salmon, Salmo sala; the butterfly, Melitaea cinxia; and the California condor, Gymnogyps californianus) in order to demonstrate the diversity of applications now possible. While it is clear that genomics approaches in conservation will not replace other tried-and-true methods, these recent developments open up an exciting new range of possibilities that will enable further diversification of the application of genomics in conservation biology.

    The AIDS Control and Prevention Project (AIDSCAP) used World AIDS Day 1993 and its theme "A Time to Act" as an opportunity to focus attention on the urgency of the struggle against AIDS. Some of the events AIDSCAP promoted included the release of hundreds of balloons inscribed with the message "Think: AIDS is Still Here" in Haiti, where a major radio station also devoted all of the day's advertising time to HIV/AIDS prevention messages; the distribution of 500,000 condoms as inserts in a major Brazilian newspaper; and a 15-km walk in Ethiopia undertaken by thousands of people to promote AIDS prevention. While such events are not expected to have a measurable impact on the epidemic, they could instigate the long-term efforts to create a social environment conducive to HIV prevention through individual behavior change. The theme chosen for the 1994 World AIDS Day is "AIDS and the Family." PMID:12345905

    Parasitic species, which depend directly on host species for their survival, represent a major regulatory force in ecosystems and a significant component of Earth's biodiversity. Yet the negative impacts of parasites observed at the host level have motivated a conservation paradigm of eradication, moving us farther from attainment of taxonomically unbiased conservation goals. Despite a growing body of literature highlighting the importance of parasite-inclusive conservation, most parasite species remain understudied, underfunded, and underappreciated. We argue the protection of parasitic biodiversity requires a paradigm shift in the perception and valuation of their role as consumer species, similar to that of apex predators in the mid-20th century. Beyond recognizing parasites as vital trophic regulators, existing tools available to conservation practitioners should explicitly account for the unique threats facing dependent species. We built upon concepts from epidemiology and economics (e.g., host-density threshold and cost-benefit analysis) to devise novel metrics of margin of error and minimum investment for parasite conservation. We define margin of error as the risk of accidental host extinction from misestimating equilibrium population sizes and predicted oscillations, while minimum investment represents the cost associated with conserving the additional hosts required to maintain viable parasite populations. This framework will aid in the identification of readily conserved parasites that present minimal health risks. To establish parasite conservation, we propose an extension of population viability analysis for host-parasite assemblages to assess extinction risk. In the direst cases, ex situ breeding programs for parasites should be evaluated to maximize success without undermining host protection.

    After the introduction of a law prohibiting the start-up of any new nuclear power plant until the utility had shown that the waste produced by the plant could be taken care of in an absolutely safe way, the Swedish nuclear utilities in December 1976 embarked on the Nuclear Fuel Safety Project, which in November 1977 presented a first report, Handling of Spent Nuclear Fuel and Final Storage of Vitrified Waste (KBS-I), and in November 1978 a second report, Handling and Final Storage of Unreprocessed Spent Nuclear Fuel (KBS II). These summary reports were supported by 120 technical reports prepared by 450 experts. The project engaged 70 private and governmental institutions at a total cost of US $15 million. The KBS-I and KBS-II reports are summarized in this document, as are also continued waste research efforts carried out by KBS, SKBF, PRAV, ASEA and other Swedish organizations. The KBS reports describe all steps (except reprocessing) in handling chain from removal from a reactor of spent fuel elements until their radioactive waste products are finally disposed of, in canisters, in an underground granite depository. The KBS concept relies on engineered multibarrier systems in combination with final storage in thoroughly investigated stable geologic formations. This report also briefly describes other activities carried out by the nuclear industry, namely, the construction of a central storage facility for spent fuel elements (to be in operation by 1985), a repository for reactor waste (to be in operation by 1988), and an intermediate storage facility for vitrified high-level waste (to be in operation by 1990). The R and D activities are updated to September 1981.

    Isotopes and nuclides are important in our everyday life. The general public and most students are never exposed to the concepts of stable and radioactive isotopes/nuclides. The National Nuclear Data Center (NNDC) is involved in an international project to develop a Periodic Table of the Isotopes for the educational community to illustrate the importance of isotopes and nuclides in understanding the world around us. This effort should aid teachers in introducing these concepts to students from the high school to the graduate school level.

Participate in discussions on larger issues such as research, funding, and treatment options. Wolf also suggests becoming educated, acting in a more public way, and finding more creative ways to act. Lastly, strive for goals with high expectations that can effect change instead of merely gathering and dispensing information.

  18. Monitoring for conservation

    2006-01-01

    Human-mediated environmental changes have resulted in appropriate concern for the conservation of ecological systems and have led to the development of many ecological monitoring programs worldwide. Many programs that are identified with the purpose of `surveillance? represent an inefficient use of conservation funds and effort. Here, we revisit the 1964 paper by Platt and argue that his recommendations about the conduct of science are equally relevant to the conduct of ecological monitoring programs. In particular, we argue that monitoring should not be viewed as a stand-alone activity, but instead as a component of a larger process of either conservation-oriented science or management. Corresponding changes in monitoring focus and design would lead to substantial increases in the efficiency and usefulness of monitoring results in conservation.

  19. Africa and the AIDS myth.

    PubMed

    Versi, A

    1990-04-01

    The recently released television documentary, "Monkey Business, AIDS: The African Story," has created controversy in Europe with its premise that AIDS did not originate in Africa. Although AIDS 1st appeared in New York in 1981 and was not recorded in Africa until 1983, researchers and the media have promoted the theory that AIDS came from Africa through human contact with the green monkey. Subsequent research forced the original champions of this "green monkey connection" theory to acknowledge that the AIDS virus and the green monkey virus are so dissimilar that they could not be historically linked. Then, the focus turned to the theory that a remote pygmy tribe had been endemically infected with the AIDS virus and carried the disease, by airplane, out of the country. This theory, too, was refuted by the failure to locate any HIV-positive pygmies in the Central African Republic. Still determined to prove that AIDS did not have an American or European origin, researchers reported that blood testing conducted in 1984 revealed 50-90% of Africans to be HIV-infected. Retesting with a more accurate procedure revealed the rate of infectivity to be only 0.02%; yet the media have continued to portray Africa as the source of the AIDS scourge. Moreover, it appears that AIDS cases are actually overreported from Africa--not underreported--due to confusion with conditions such as malnutrition and tropical diseases. To some, this relentless drive to vilify Africa reflects racism. Others believe that it represents an effort to cover up the possibility that the AIDS virus is man-made--a result of an accident in gene technology or microbiology.

  2. AIDS in women: epidemiology.

    PubMed

    Willoughby, A

    1989-09-01

    Several facts concerning the distribution of AIDS in U.S. female populations are clear. This disease has made significant inroads, in a quantitative sense, into the female segment of our society as documented by AIDS surveillance data, information on pregnant women and parturients, and by screening data from the military. The impact on women in the reproductive years, on the reproductive health of these women, and on the reproductive outcome of their pregnancies is of substantial concern. Monitoring epidemiologic trends in certain groups will require clever and creative strategies like those of Hoff and colleagues. Additional data may be derived from the CDC's Family of Surveys that will examine HIV prevalence in five groups (in addition to the newborn infant survey described above): intravenous drug users, patients admitted to hospitals, sexually transmitted disease clinic patients, women's health and reproductive health clinics, and tuberculosis clinics. It is hoped that the data obtained from these studies, as well as data gathered on college students and Job Corps applicants, will contribute additional information on HIV infection in women. Monitoring the progress of the AIDS epidemic in women will be difficult. Even more difficult will be the effort to respond to the epidemic in the women it most frequently affects: the poor, minority, disenfranchised women who may be involved in illegal activities (drug use, prostitution, illegal immigration) who are not well networked into the medical and social services of our society.

    This book is the first attempt to examine collectively the various uses and the consequences of marsh conservation efforts. Author Franklin Daiber emphasizes tidal marsh conservation from a holistic perspective rather than from the perspective of a single purpose or special economic interest. He addresses a topic receiving increasing attention, namely the concept of open marsh management as a means of controlling mosquito production without harmful effects on other marsh organisms. Topics considered include: water management; dikes, impoundments, ponds and ditches; reclaimed land and impoundments; ditching and ponding for mosquito control; sewage disposal and waste treatment; dredge material for wetland restoration; insecticides; oil pollution; and petroleum hydrocarbon interactions.

  4. AIDS and family planning.

    1992-01-01

    In 1991, an HIV prevention program advisor and a research/evaluation specialist for family planning programs discussed problems that affected HIV prevention and family planning services in Haiti before and after the coup of the Aristide government. Population activities began aimlessly in 1974 and HIV prevention efforts only began in 1988. After the coup, Haitians lost their newly found hope for meaningful development. All foreign assistance ended and they did not trust the army. In fact, other than essential child survival activities, no health and family planning services operated for several weeks. The situation grew worse after the economic embargo. 3 months after the coup, the US considered adding family planning assistance. Still little movement of condom, family planning, and health supplies left Port-au-Prince for the provinces which adversely affected all health related efforts. Condoms could no longer be distributed easily either in the socially marketed or US supplied condom distribution programs. Before the coup, HIV prevention and family planning programs depended on peer educators to educate the public (this approach made these programs quite successful), but the 2 experts feared that they would not return to those roles and that these programs would need to completely rebuild. Another concern was the large scale urban-rural migration making it difficult for them to continue care. Early in the AIDS epidemic, the Haitian government was on the defensive because the US considered Haitians as a high risk group so it did little to prevent HIV transmission. After 1988, HIV prevention activities in Haiti centered on raising awareness and personalizing the epidemic. The AIDS specialist noted, however, that a major obstacle to increasing knowledge is that AIDS is just 1 of many fatal diseases in Haiti. Moreover few health professionals in Haiti have ever had public health training. PMID:12159262

    A promilitary coalition began to govern Thailand in March 1992. It reduced the budget for the original proposed national AIDS awareness campaign from 30 million British pounds to almost 15 million British pounds. The Ministry of Health professed that the campaign had exaggerated the problem of AIDS in Thailand and had damaged tourism. Yet prodemocracy demonstrations in Bangkok in which troops killed many protesters restored the politicians who started the AIDS campaign to power in May 1992. There were to remain in power until new elections in September 1992. In July, the Minister of Health, Mechai Viravaidya, said he would step down if the government did not completely restore the 30 million British pounds for the AIDS campaign. It then increased the budget to almost that amount. Mr. Viravaidya initiated Thailand's open policy on the AIDS crisis and was known as Mr. Condom. He claimed that at the present HIV prevalence rate, Thailand may have between 2-4 million HIV infected people by 2000. If the country would take on anti-AIDS efforts now, however, they could cut the spread of HIV by 75%. As of mid-1992, about 400,000 people living in Thailand were HIV positive. The AIDS campaign planned to sue the mass media to inform people about AIDS especially those in universities and schools and high risk occupational groups. The increasing number of construction workers in Bangkok and existing sex workers were a high risk occupational group. At the 2nd national seminar of AIDS, the Minister of Health reproached tourists who come to Thailand for its sex industry. He said that Thailand does not need the 1 billion British pounds they bring to Thailand annually, and Thais do not want their homeland to be referred to as the sex capital.

    Cognitive effort has been implicated in numerous theories regarding normal and aberrant behavior and the physiological response to engagement with demanding tasks. Yet, despite broad interest, no unifying, operational definition of cognitive effort itself has been proposed. Here, we argue that the most intuitive and epistemologically valuable treatment is in terms of effort-based decision-making, and advocate a neuroeconomics-focused research strategy. We first outline psychological and neuroscientific theories of cognitive effort. Then we describe the benefits of a neuroeconomic research strategy, highlighting how it affords greater inferential traction than do traditional markers of cognitive effort, including self-reports and physiologic markers of autonomic arousal. Finally, we sketch a future series of studies that can leverage the full potential of the neuroeconomic approach toward understanding the cognitive and neural mechanisms that give rise to phenomenal, subjective cognitive effort.

It is part of an overall effort to inform utilities of technological developments in conservation and renewable energy technologies and so aid utilities in their planning process to determine the most effective and economic combination of capital investments to meet customer needs. Department of Energy assessments of the applications, current costs and cost goals for the various technologies included in this bibliography are presented. These assessments are based on analyses performed by or for the respective DOE Program Offices. The results are sensitive to a number of variables and assumptions; however, the estimates presented are considered representative. These assessments are presented, followed by some conclusions regarding the potential role of the conservation and renewable energy alternative. The approach used to classify the bibliographic citations and abstracts is outlined.

    Concerns regarding the long-term viability of threatened and endangered plant species are increasingly warranted given the potential impacts of climate change and habitat fragmentation on unstable and isolated populations. Orchidaceae is the largest and most diverse family of flowering plants, but it is currently facing unprecedented risks of extinction. Despite substantial conservation emphasis on rare orchids, populations continue to decline. Spiranthes parksii (Navasota ladies' tresses) is a federally and state-listed endangered terrestrial orchid endemic to central Texas. Hence, we aimed to identify potential factors influencing the distribution of the species, quantify the relative importance of each factor and determine suitable habitat for future surveys and targeted conservation efforts. We analysed several geo-referenced variables describing climatic conditions and landscape features to identify potential factors influencing the likelihood of occurrence of S. parksii using boosted regression trees. Our model classified 97 % of the cells correctly with regard to species presence and absence, and indicated that probability of existence was correlated with climatic conditions and landscape features. The most influential variables were mean annual precipitation, mean elevation, mean annual minimum temperature and mean annual maximum temperature. The most likely suitable range for S. parksii was the eastern portions of Leon and Madison Counties, the southern portion of Brazos County, a portion of northern Grimes County and along the borders between Burleson and Washington Counties. Our model can assist in the development of an integrated conservation strategy through: (i) focussing future survey and research efforts on areas with a high likelihood of occurrence, (ii) aiding in selection of areas for conservation and restoration and (iii) framing future research questions including those necessary for predicting responses to climate change.

    Daniel, H

    1991-01-01

    Although AIDS was expected in Brazil, no serious efforts were undertaken to prevent AIDS from taking root. Irresponsible press and media coverage highlighted the spread of AIDS within the gay community of the United States, creating an aura of immunity in Brazil to what was characterized as a "foreign" disorder. When AIDS did surface in 1983, the official response was to adopt an abstract, inappropriate, and ideological "Western" model, in which only stigmatized "others" and "minorities" were at risk of HIV infection. Brazilian health authorities subsequently downplayed the significance of the sale of contaminated blood in HIV transmission, and likewise ignored the rising rates of AIDS among Brazil's one unarguable majority group: the poor. An analysis of efforts to force the "facts" of AIDS to fit a false model's predictions leads to a clearer definition of the broader context of the Brazilian epidemic: we all are people living with AIDS, precisely because we live in this age of AIDS; it is sheer folly to discriminate against persons infected by HIV and to obstruct their participation in efforts to curtail the epidemic's spread; and the necessary response to AIDS is solidarity, not because it is poetic, but because no other response will suffice.

    1996-05-20

    The conservative Islamic society in Pakistan associates human immunodeficiency virus (HIV) infections and acquired immunodeficiency syndrome (AIDS) with prostitution, homosexuality, and drug abuse, activities which are prohibited in Pakistan. There are 1000 reported cases of HIV, 55 with advanced AIDS (53 have died) in Pakistan. Birjees Mazhar Kazi, head of the National AIDS Program, believes that, based on the computer model of the World Health Organization (WHO), the number of HIV cases in Pakistan can be 50,000 to 80,000. Prime Minister Benazir Bhutto's government has allocated $2 million for AIDS prevention. Although some officials argue that Islamic strictures and traditional social pressures discourage sexual license, the poor public health and education standards in Pakistan make it vulnerable to AIDS. Drug abuse has risen in the last 20 years; there are an estimated 1.5 million heroin users among an estimated 3 million addicts. According to Health Ministry Director General Naik Muhammad Shaikh, the government has established 30 HIV/AIDS screening centers and is sponsoring a law that would require all blood banks to provide only safe blood and blood products for transfusion. Marvi states that the reuse and poor disposal of needles, a common practice in Pakistan, could be responsible for most of the transmission there of AIDS and hepatitis C. Health experts acknowledge the obstacles placed in the way of AIDS awareness campaigns by sex taboos and religious sensitivities; condoms cannot be mentioned or displayed in shops, or used in electronic or print media campaigns. They can be mentioned in a recorded message on a 24-hr AIDS hotline. Community-based and nongovernmental organizations are being used to reach segments of society who cannot use the hotline.

    The Institute for the Achievement of Human Potential developed a device known as the Vehicle for Initial Crawling (VIC); the acronym is a tribute to the crawler's inventor, Hubert "Vic" Vykukal; is an effective crawling aid. The VIC is used by brain injured children who are unable to crawl due to the problems of weight-bearing and friction, caused by gravity. It is a rounded plywood frame large enough to support the child's torso, leaving arms and legs free to move. On its underside are three aluminum discs through which air is pumped to create an air-bearing surface that has less friction than a film of oil. Upper side contains the connection to the air supply and a pair of straps which restrain the child and cause the device to move with him. VIC is used with the intent to recreate the normal neurological connection between brain and muscles. Over repetitive use of the device the child develops his arm and leg muscles as well as coordination. Children are given alternating therapy, with and without the VIC until eventually the device is no longer needed.

The RSA has been a rapid prototyping effort whose purpose is to elucidate and define suitable technology for enhancing the performance of the range schedulers. Designing a system to assist schedulers in their task and using their current techniques as well as enhancements enabled by an electronic environment, has created a continuously developing model that will serve as a standard for future range scheduling systems. The RSA system is easy to use, easily ported between platforms, fast, and provides a set of tools for the scheduler that substantially increases his productivity.

    Leadership is a critical tool for expanding the influence of conservation science, but recent advances in leadership concepts and practice remain underutilized by conservation scientists. Furthermore, an explicit conceptual foundation and definition of leadership in conservation science are not available in the literature. Here we drew on our diverse leadership experiences, our reading of leadership literature, and discussions with selected conservation science leaders to define conservation-science leadership, summarize an exploratory set of leadership principles that are applicable to conservation science, and recommend actions to expand leadership capacity among conservation scientists and practitioners. We define 2 types of conservation-science leadership: shaping conservation science through path-breaking research, and advancing the integration of conservation science into policy, management, and society at large. We focused on the second, integrative type of leadership because we believe it presents the greatest opportunity for improving conservation effectiveness. We identified 8 leadership principles derived mainly from the "adaptive leadership" literature: recognize the social dimension of the problem; cycle frequently through action and reflection; get and maintain attention; combine strengths of multiple leaders; extend your reach through networks of relationships; strategically time your effort; nurture productive conflict; and cultivate diversity. Conservation scientists and practitioners should strive to develop themselves as leaders, and the Society for Conservation Biology, conservation organizations, and academia should support this effort through professional development, mentoring, teaching, and research.

  11. Physiology in conservation translocations.

    Conservation translocations aim to restore species to their indigenous ranges, protect populations from threats and/or reinstate ecosystem functions. They are particularly important for the conservation and management of rare and threatened species. Despite tremendous efforts and advancement in recent years, animal conservation translocations generally have variable success, and the reasons for this are often uncertain. We suggest that when little is known about the physiology and wellbeing of individuals either before or after release, it will be difficult to determine their likelihood of survival, and this could limit advancements in the science of translocations for conservation. In this regard, we argue that physiology offers novel approaches that could substantially improve translocations and associated practices. As a discipline, it is apparent that physiology may be undervalued, perhaps because of the invasive nature of some physiological measurement techniques (e.g. sampling body fluids, surgical implantation). We examined 232 publications that dealt with translocations of terrestrial vertebrates and aquatic mammals and, defining 'success' as high or low, determined how many of these studies explicitly incorporated physiological aspects into their protocols and monitoring. From this review, it is apparent that physiological evaluation before and after animal releases could progress and improve translocation/reintroduction successes. We propose a suite of physiological measures, in addition to animal health indices, for assisting conservation translocations over the short term and also for longer term post-release monitoring. Perhaps most importantly, we argue that the incorporation of physiological assessments of animals at all stages of translocation can have important welfare implications by helping to reduce the total number of animals used. Physiological indicators can also help to refine conservation translocation methods. These approaches fall under a

    Adventurers and Scientists for Conservation (ASC) is a nonprofit organization that collects environmental data to catalyze conservation initiatives worldwide. Adventure athletes have the skills and motivation to reach the most remote corners of the world. ASC utilizes those skills to provide the scientific community with data while providing the outdoor community with purpose beyond the personal high of reaching a summit or rowing across an ocean. We carefully select projects, choosing partnerships that will maximize the impact of ASC volunteers. Each project must have a clear path to a tangible conservation outcome and demonstrate a clear need for our brand of volunteers. We partner with government agencies, universities, and independant reseachers to kickstart data collection efforts around the world. Last year, through a partnership with the Olympic National Forest, 20 volunteers from the Seattle area set up and monitored camera traps in an effort to survey for costal Pacific marten. Our work led to the species' listing as "critically imperiled" with NatureServe. A partnership with the inaugural Great Pacific Race, engaging trans-Pacific rowing teams, searched for microplastics in the Pacific Ocean as part of our ongoing microplastics campaign. In a multi-year partnership with the American Prairie Reserve (APR), ASC volunteer crews live and work on the Reserve collecting wildlife data year round. The data we obtain directly informs the Reserve's wildlife management decisions. On this project, our crews have safely and effectively navigated temperature extremes from -30 degrees to 100+ degrees while traveling in a remote location. We are currently scouting projects in the Okavango Delta of Botswana and the rainforest of Suriname where we will be able to cover large amounts of area in a short periord of time. ASC is at the crossroads of the adventure and coservation science communities. Our approach of answering specific questions by using highly skilled and

    The Acquired Immune Deficiency Syndrome (AIDS) distribution program in Brazil, spearheaded by the National Division of Sanitary Surveillance in Ports, Airports, and Borders, was part of the government's massive education campaign to prevent the transmission of HIV-AIDS in Brazil. Beginning in February 1987, the climate was sufficiently favorable to operate a coordinated information campaign during the Carnival celebration, and tourists arriving in the cities of Brazil for the annual Carnival celebration were handed an educational brochure in Portugese, Spanish, English, and French. Yet, beyond reaching the tourist populations, it is particularly important to reach large portions of the Brazilian population. Planners of the national AIDS campaign intend to use television, radio, and all major newspapers in their effort to cover the country. Initial television coverage is comprised of short informational messages directed at high-risk groups. There also are plans to use radio and the print media in order to reach a wider audience. It is estimated that US $6 million will be needed to adequately meet the costs of AIDS prevention and medical care, but due to extreme budget constraints, only $45,000 has been earmarked for ongoing AIDS activities at this time.

  15. Asia: fastest growing AIDS problem.

    PubMed

    A recent UN report noted that the HIV/AIDS epidemic is growing faster in Asia than in any other region. Recent figures indicate that 2.3% of adults in Thailand are infected, and 50,000 die annually from AIDS. It is estimated that, by the year 2000, 12 million Asians could be infected and that the economic burden of this epidemic could be as high as $52 billion as the work force is lost to the disease. The increased incidence of tuberculosis (TB) is adding to the problem, with India, China, Bangladesh, Pakistan, Indonesia, and the Philippines together contributing half of the world's TB cases. Efforts to fight these epidemics are hampered by political unrest, religious opposition, the economic crisis, and poverty. Worldwide, 5.8 million people have become infected with HIV/AIDS this year, bringing the total number of those infected to 33 million. Children under age 15 account for 90% of the 590,000 new cases in sub-Sahara Africa, a region which expects 2 million AIDS deaths this year. In developed countries, new drug therapies have reduced AIDS deaths, but the rate of new infection remains unchanged.

  16. Ecological carryover effects complicate conservation.

    2015-10-01

    Ecological carryover effects occur when an individual's previous history and experiences explain their current performance. It is becoming clear that ecological carryover effects are a common phenomenon across taxa, and have the potential to play an important role in governing individual fitness and population dynamics. Carryover effects may reduce the success of conservation efforts aimed at slowing or reversing biodiversity loss. Failure to consider carryover effects might lead to erroneous conclusions about the effectiveness of conservation measures. We suggest that carryover effects are considered explicitly in threat assessment and conservation planning, in order to understand the long-term consequences of stressors, target efforts more effectively, and ensure that the success or failure of conservation efforts is tracked more accurately. We encourage proactive research focused on the proximate mechanisms underlying carryover effects, so that predictive measures of carryover effects in wild populations can be developed and refined. Finally, we suggest that in some cases, positive carryover effects could be exploited for conservation benefit. We conclude that the failure to consider carryover effects in conservation science and practice may put imperiled populations at further risk.

    2009-01-01

    There are numerous problems with the hypothesis that brain dopamine (DA) systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in behavioral activation and effort-related processes. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA depleted rats are more sensitive to increases in response costs (i.e., ratio requirements). Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and instead these rats select a less-effortful type of food-seeking behavior. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum) also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as energy-related disorders such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.

    In its report, Acid Rain Invades Our National Parks, the National Parks and Conservation Association (NPCA) says acid rain is being detected at all 27 national park monitoring sites. In 1980, 87 national parks expressed concern in a NPCA survey over acid rain. Repolled in 1986, more than half of the respondents reported that no research on acid rain was under way. The NPCA report concludes that the alarm that was sounded in 1980 fell largely on deaf ears, and calls for the structural and scientific reorganization of the National Park Service. The National Audubon Society shares NPCA's dissatisfaction with federal efforts to tackle the problem of acid rain and has taken testing into its own hands. Through its Citizens Acid Rain Monitoring Network, Audubon volunteers have collected readings of acidity at 64 monitoring stations in 31 states since July.

    The relations among peer victimization, effortful control, school engagement, and academic achievement were examined in a group of 390 (212 boys and 178 girls) racially diverse (38.20% Latino and 46.70% White) 6- to 10-year-old children. Specifically, a multimethod, multi-informant approach was used in which data were gathered using self-report, peer-report, and teacher-report questionnaires at three points in time: twice during the initial year of the study when children were in first and third grades and once in the fall of their second-grade and fourth-grade years, respectively. Findings showed that peer victimization was negatively correlated with effortful control; however, longitudinal analyses conducted to examine causal priority were inconclusive. Results from structural equation modeling were consistent with the hypotheses that school engagement mediated the relations between peer victimization and academic achievement, as well as between effortful control and academic achievement.

The idea behind this effort was to bring nuclear energy closer to the needs of sustainability, to increase proliferation resistance, and to support concepts able to produce energy (both electricity and process heat) at competitive costs. The U.S. Department of Energy has supported this effort by pursuing the development of the Next Generation Nuclear Plant, a high temperature gas-cooled reactor. This support has included research and development of pertinent data, initial regulatory discussions, and engineering support of various codes and standards development. This report discusses the various applicable American Society of Mechanical Engineers (ASME) codes and standards that are being developed to support these high temperature gascooled reactors during construction and operation.

  7. A review of the key genetic tools to assist imperiled species conservation: analyzing West Indian manatee populations

    2012-01-01

    Managers faced with decisions on threatened and endangered wildlife populations often are lacking detailed information about the species of concern. Integration of genetic applications will provide management teams with a better ability to assess and monitor recovery efforts on imperiled species. The field of molecular biology continues to progress rapidly and many tools are currently available. Presently, little guidance is available to assist researchers and managers with the appropriate selection of genetic tools to study the status of wild manatee populations. We discuss several genetic tools currently employed in the application of conservation genetics, and address the utility of using these tools to determine population status to aid in conservation efforts. As an example, special emphasis is focused on the endangered West Indian manatee (Order Sirenia). All four extant species of sirenians are imperiled throughout their range, predominately due to anthropogenic sources; therefore, the need for genetic information on their population status is direly needed.

  8. Lyme disease and conservation

    USGS Publications Warehouse

    Ginsberg, H.

    1994-01-01

    Lyme disease is a tick-borne illness that is wide-spread in North America, especially in the northeastern and northcentral United States. This disease could negatively influence efforts to conserve natural populations in two ways: (1) the disease could directly affect wild animal health; and (2) tick control efforts could adversely affect natural populations and communities. Lyme disease affects several domestic animals, but symptoms have been reported in only a few wild species. Direct effects of Lyme disease on wild animal populations have not been reported, but the disease should be considered as a possible cause in cases of unexplained population declines in endemic areas. Methods available to manage ticks and Lyme disease include human self-protection techniques, manipulation of habitats and hosts species populations, biological control, and pesticide applications. The diversity of available techniques allows selection of approaches to minimize environmental effects by (1) emphasizing personal protection techniques, (2) carefully targeting management efforts to maximize efficiency, and (3) integrating environmentally benign techniques to improve management while avoiding broad-scale environmentally destructive approaches. The environmental effects of Lyme disease depend, to a large extent, on the methods chosen to minimize human exposure to infected ticks. Conservation biologists can help design tick management programs that effectively lower the incidence of human Lyme disease while simultaneously minimizing negative effects on natural populations.

The focus is on conservation of the complex ecosystem with sustainable development by showing local people how to benefit from the park without environmental damage. Cultural diversity is as important as biological diversity. The area has been designated by UNESCO as a World Heritage Site with the "last pure ecological seed" of the Himalayas. The regional geography and culture are presented. Population growth has impacted natural resources through overgrazing, cultivation of marginal land, and deforestation; future plans to build a dam and road bordering the nature reserve pose other threats. Proposed management plans for the Makalu-Barun Nature Park (established in November 1991) and Conservation Area include a division of the park into nature reserve areas free of human activity, protected areas which permit traditional land use, and special sites and trail for tourists and religious pilgrims. The conservation area will act as a buffer for the park and provide economic opportunities; further subdivisions include land use for biodiversity protection, community forest and pasture, agroforestry, and agriculture and settlement. Efforts will be made to increase the welfare of women and local people; proposed projects include the introduction of higher milk-producing animals for stall feeding. Also proposed is a cultural and natural history museum. 70% of the project's resources will be directed to local community participation in consultation and park maintenance. The project is a model of how conservation and protection of natural resources can coexist with local economic development and participation; an integration of preservation of biological diversity, mountain wisdom, and the value of local people as resources for conservation.

    2013-01-01

    As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

    The author is an AIDS educator working in Vancouver, Canada, who does not agree with current HIV prevention tactics which bombard audiences with information on HIV and its consequences and preventive approaches. It should be clear by now that inundating people with information while ignoring the emotions behind their choices does not work. Efforts must be made to close the gap between individual knowledge and action. The author has learned over his four-year tenure as youth educator that educational sessions should be small and interactive. The educator should stress that no question, topic, feeling, or prejudice is taboo and encourage open discussion of pertinent issues. No person should be allowed to dominate the discussion and only minimal time spent on topics such as whether mosquitoes can transmit HIV. The focus should be taken off of condoms, because people have heard enough already, and alternatives to unprotected anal, vaginal, and oral sex encouraged. Women should be encouraged to choose what kind of sex they want, participants should be encouraged to discuss and adhere to what they have learned after the session, and obstacles raise by conservative parents' groups must be fought. Further, the educator must prepare for the session and follow up on opinions afterwards. The author also critiques Catholic education as puritan and disrespectful of the rights of youth to information and free choice, and assails discrimination against people with AIDS and all people in general.

  19. Energy conservation technologies

    The conservation of energy through the efficiency improvement of existing end-uses and the development of new technologies to replace less efficient systems is an important component of the overall effort to reduce greenhouse gases which may contribute to global climate change. Even though uncertainties exist on the degree and causes of global warming, efficiency improvements in end-use applications remain in the best interest of utilities, their customers and society because efficiency improvements not only reduce environmental exposures but also contribute to industrial productivity, business cost reductions and consumer savings in energy costs.

  20. The Telemetry Agile Manufacturing Effort

    1995-01-01

    The Telemetry Agile Manufacturing Effort (TAME) is an agile enterprising demonstration sponsored by the US Department of Energy (DOE). The project experimented with new approaches to product realization and assessed their impacts on performance, cost, flow time, and agility. The purpose of the project was to design the electrical and mechanical features of an integrated telemetry processor, establish the manufacturing processes, and produce an initial production lot of two to six units. This paper outlines the major methodologies utilized by the TAME, describes the accomplishments that can be attributed to each methodology, and finally, examines the lessons learned and explores the opportunities for improvement associated with the overall effort. The areas for improvement are discussed relative to an ideal vision of the future for agile enterprises. By the end of the experiment, the TAME reduced production flow time by approximately 50% and life cycle cost by more than 30%. Product performance was improved compared with conventional DOE production approaches.

  2. Conservation and ethnobotanical exploration.

    PubMed

    Martin, G J

    1994-01-01

    In recent years conservationists have realized that the maintenance of protected areas is closely linked to rural development. As part of their efforts to improve local people's standards of living, they have sought the advice of researchers who work in communities, especially those that border on nature reserves. Ethnobotanists, who are turning their attention to the cultural and ecological crises confronting the regions in which they work, are natural allies in this venture. The joint efforts of conservationists and ethnobotanists are being supported by non-profit organizations, intergovernmental agencies and research institutes. The search for new drugs and other natural products from plants is an important element in this collaboration, but it cannot be divorced from the broader objective of promoting the survival of biological and cultural diversity. Conservationists will support biodiversity prospecting and related efforts only if there is a clear benefit for local communities and protected areas. An example of the concrete actions being taken by conservation agencies is the People and Plants Initiative, a joint effort of the World Wide Fund for Nature, the United Nations Educational, Scientific and Cultural Organization and the Royal Botanic Gardens, Kew. The main objective is to support the work of ethnobotanists in developing countries in studies of sustainable plant use and application of their work to conservation and community development. The initiative provides training workshops and relevant literature; coordinators work in collaboration with local people to create inventories of useful plants and appraise the impact of harvesting specific plant resources in and around protected areas. Phytochemical screening of medicinal plants and preparation of extracts are carried out as part of some projects.

  3. New Horizons Launch Contingency Effort

    2007-01-01

    On 19 January 2006 at 2:00 PM EST, the NASA New Horizons spacecraft (SC) was launched from the Cape Canaveral Air Force Station (CCAFS), FL, onboard an Atlas V 551/Centaur/STAR™ 48B launch vehicle (LV) on a mission to explore the Pluto Charon planetary system and possibly other Kuiper Belt Objects. It carried a single Radioisotope Thermoelectric Generator (RTG). As part of the joint NASA/US Department of Energy (DOE) safety effort, contingency plans were prepared to address the unlikely events of launch accidents leading to a near-pad impact, a suborbital reentry, an orbital reentry, or a heliocentric orbit. As the implementing organization. The Johns Hopkins University Applied Physics Laboratory (JHU/APL) had expanded roles in the New Horizons launch contingency effort over those for the Cassini mission and Mars Exploration Rovers missions. The expanded tasks included participation in the Radiological Control Center (RADCC) at the Kennedy Space Center (KSC), preparation of contingency plans, coordination of space tracking assets, improved aerodynamics characterization of the RTG's 18 General Purpose Heat Source (GPHS) modules, and development of spacecraft and RTG reentry breakup analysis tools. Other JHU/APL tasks were prediction of the Earth impact footprints (ElFs) for the GPHS modules released during the atmospheric reentry (for purposes of notification and recovery), prediction of the time of SC reentry from a potential orbital decay, pre-launch dissemination of ballistic coefficients of various possible reentry configurations, and launch support of an Emergency Operations Center (EOC) on the JHU/APL campus. For the New Horizons launch, JHU/APL personnel at the RADCC and at the EOC were ready to implement any real-time launch contingency activities. A successful New Horizons launch and interplanetary injection precluded any further contingency actions. The New Horizons launch contingency was an interagency effort by several organizations.

    2000-01-01

    Herons are large, popular and, in many cases, spectacular birds found in wetlands world-wide, both tropical and temperate, natural and man-made. Some populations are very small and localized, some have decreased, some have expanded their ranges, and a few are pests of human activities. In the fifteen years since the publication of the latest monographic treatment of the family, The Herons Handbook, there has been a tremendous increase in our knowledge of heron status and conservation requirements, set against a backdrop of increasing concern about the future of the world?s wetland habitats. This book provides a comprehensive update following two distinct threads. The status and conservation needs of herons are first presented on a regional basis, in a series of chapters set at a continental or subcontinental scale. Over 200 biologists and heron conservationists have contributed to the data summarized here, and the very latest census and survey results provide the most up-to-date and detailed picture of heron populations currently available. Chapters discussing several critical issues in heron conservation follow, tending to focus on the international nature of the problems.

    In the present study, GRL008, a novel nonpeptidic human immunodeficiency virus type 1 (HIV-1) protease inhibitor (PI), and darunavir (DRV), both of which contain a P2-bis-tetrahydrofuranyl urethane (bis-THF) moiety, were found to exert potent antiviral activity (50% effective concentrations [EC50s], 0.029 and 0.002 μM, respectively) against a multidrug-resistant clinical isolate of HIV-1 (HIVA02) compared to ritonavir (RTV; EC50, >1.0 μM) and tipranavir (TPV; EC50, 0.364 μM). Additionally, GRL008 showed potent antiviral activity against an HIV-1 variant selected in the presence of DRV over 20 passages (HIVDRVRP20), with a 2.6-fold increase in its EC50 (0.097 μM) compared to its corresponding EC50 (0.038 μM) against wild-type HIV-1NL4-3 (HIVWT). Based on X-ray crystallographic analysis, both GRL008 and DRV showed strong hydrogen bonds (H-bonds) with the backbone-amide nitrogen/carbonyl oxygen atoms of conserved active-site amino acids G27, D29, D30, and D30′ of HIVA02 protease (PRA02) and wild-type PR in their corresponding crystal structures, while TPV lacked H-bonds with G27 and D30′ due to an absence of polar groups. The P2′ thiazolyl moiety of RTV showed two conformations in the crystal structure of the PRA02-RTV complex, one of which showed loss of contacts in the S2′ binding pocket of PRA02, supporting RTV's compromised antiviral activity (EC50, >1 μM). Thus, the conserved H-bonding network of P2-bis-THF-containing GRL008 with the backbone of G27, D29, D30, and D30′ most likely contributes to its persistently greater antiviral activity against HIVWT, HIVA02, and HIVDRVRP20.

    The purpose of this study is to identify and quantify potential energy savings available through the development and application of biotechnologies. This information is required in support of ECUT research planning efforts as an aid in identifying promising areas needing further consideration and development. It is also intended as background information for a companion ECUT study being conducted by the National Academy of Science to evaluate the use of bioprocessing methods to conserve energy. Several studies have been conducted recently to assess the status and implications of the development of biotechnology. The Office of Technology Assessment (OTA) considered institutional, economic, and scientific problems and barriers. The National Science Foundation sponsored a study to examine regulatory needs for this new and expanding technology. Somewhat in contrast to these studies, this report covers principally the technical issues. It should be emphasized that the practicality of many developments in biotechnology is not evaluated solely on the basis of energy considerations. Bioprocesses must often compete with well-established coal, petroleum, and natural gas technologies. A complete evaluation of the technical, economical, and ecological impacts of the large-scale applications discussed in this report is not possible within the scope of this study. Instead, this report assesses the potential of biotechnology to save energy so that research into all aspects of implementation will be stimulated for those industries with significant energy savings potential. 92 references, 6 figures, 24 tables.

    Genomic approaches are gathering momentum in biology and emerging opportunities lie in the creative use of comparative molecular methods for revealing the processes that influence diversity of wildlife. However, few comparative genomic studies are performed with explicit and specific objectives to aid conservation of wild populations. Here I provide a brief overview of comparative genomic approaches that offer specific benefits to biodiversity conservation. Because conservation examples are few, I draw on research from other areas to demonstrate how comparing genomic data across taxa may be used to inform the characterisation of conservation units and studies of hybridisation, as well as studies that provide conservation outcomes from a better understanding of the drivers of divergence. A comparative approach can also provide valuable insight into the threatening processes that impact rare species, such as emerging diseases and their management in conservation. In addition to these opportunities, I note areas where additional research is warranted. Overall, comparing and contrasting the genomic composition of threatened and other species provide several useful tools for helping to preserve the molecular biodiversity of the global ecosystem.

    American Physical Society (APS) has a wide range of education and diversity programs and activities, including programs that improve physics education, increase diversity, provide outreach to the public, and impact public policy. We present the latest programs spearheaded by the Committee on the Status of Women in Physics (CSWP), with highlights from other diversity and education efforts. The CSWP is working to increase the fraction of women in physics, understand and implement solutions for gender-specific issues, enhance professional development opportunities for women in physics, and remedy issues that impact gender inequality in physics. The Conferences for Undergraduate Women in Physics, Professional Skills Development Workshops, and our new Professional Skills program for students and postdocs are all working towards meeting these goals. The CSWP also has site visit and conversation visit programs, where department chairs request that the APS assess the climate for women in their departments or facilitate climate discussions. APS also has two significant programs to increase participation by underrepresented minorities (URM). The newest program, the APS National Mentoring Community, is working to provide mentoring to URM undergraduates, and the APS Bridge Program is an established effort that is dramatically increasing the number of URM PhDs in physics.

    The National Spherical Torus Experiment (NSTX) is a low aspect ratio, spherical torus (ST) configuration device which is located at Princeton Plasma Physics Laboratory (PPPL) This device is presently being updated to enhance its physics by doubling the TF field to 1 Tesla and increasing the plasma current to 2 Mega-amperes. The upgrades include a replacement of the centerstack and addition of a second neutral beam. The upgrade analyses have two missions. The first is to support design of new components, principally the centerstack, the second is to qualify existing NSTX components for higher loads, which will increase by a factor of four. Cost efficiency was a design goal for new equipment qualification, and reanalysis of the existing components. Showing that older components can sustain the increased loads has been a challenging effort in which designs had to be developed that would limit loading on weaker components, and would minimize the extent of modifications needed. Two areas representing this effort have been chosen to describe in more details: analysis of the current distribution in the new TF inner legs, and, second, analysis of the out-of-plane support of the existing TF outer legs.

    SciTech Connect

    Simpson, P.

    1995-06-01

    There are two fundamental reasons or motivations for energy conservation: (1) economics; and (2) consideration of energy - its sources and availability. Economics speaks for itself and needs little explanation: a project is undertaken, the cost is recovered in a given period of time (we hope) and our company realizes cost savings thereafter. We study and propose a project; we estimate the payback. If approved, we implement the project. Then, we eagerly watch for its effectiveness - for the proposed payback. The second consideration in regard to energy conservation might - in the foreseeable future - become by far the most important - that of availability. Very knowledgeable persons have stated that this - in reality - is the most serious problem facing our nation today. Readily available, reasonably priced energy has given to the US the high form of living experienced today. An interruption in this flow could catapult our nation in an awesome catastrophe. The energy shortage of the late 70`s might be a forerunner of such an experience.

    Conservative Remapper (CORE) is a C++ language software library for remapping cell masses and cell-averaged densities on unstructured two dimensional grids, maintaining conservation of total mass in the process. CORE contains implementation of two remapping algorithms: a new, efficient "swept region" algorithm, and a more traditional algorithm basedon the computation of cell intersections. Grids may be Cartesian or cylindrical, and cells may have three or more vertices, with no upper limit. CORE can run inmore » serial and in parallel, but in order to achieve wide applicability, CORE used no particular parallel communication library. Instead it achieves parallel communication through strategically placed, user defined callbacks. Users can also provide callbacks to redefine different parts or subcomponents of the remapping process. CORE allows the use of different data types, e.g. single-, double-, and quadruple- precision floating-point numbers, through the use of C++ templates. Using CORE is simple, and requires no configuration scripts or makefiles.« less

    Martin, Tara G.; Chadès, Iadine; Arcese, Peter; Marra, Peter P.; Possingham, Hugh P.; Norris, D. Ryan

    2007-01-01

    Background Migratory animals comprise a significant portion of biodiversity worldwide with annual investment for their conservation exceeding several billion dollars. Designing effective conservation plans presents enormous challenges. Migratory species are influenced by multiple events across land and sea–regions that are often separated by thousands of kilometres and span international borders. To date, conservation strategies for migratory species fail to take into account how migratory animals are spatially connected between different periods of the annual cycle (i.e. migratory connectivity) bringing into question the utility and efficiency of current conservation efforts. Methodology/Principal Findings Here, we report the first framework for determining an optimal conservation strategy for a migratory species. Employing a decision theoretic approach using dynamic optimization, we address the problem of how to allocate resources for habitat conservation for a Neotropical-Nearctic migratory bird, the American redstart Setophaga ruticilla, whose winter habitat is under threat. Our first conservation strategy used the acquisition of winter habitat based on land cost, relative bird density, and the rate of habitat loss to maximize the abundance of birds on the wintering grounds. Our second strategy maximized bird abundance across the entire range of the species by adding the constraint of maintaining a minimum percentage of birds within each breeding region in North America using information on migratory connectivity as estimated from stable-hydrogen isotopes in feathers. We show that failure to take into account migratory connectivity may doom some regional populations to extinction, whereas including information on migratory connectivity results in the protection of the species across its entire range. Conclusions/Significance We demonstrate that conservation strategies for migratory animals depend critically upon two factors: knowledge of migratory

    90% of HIV infections take place in the developing world. In Southeast Asia, an estimated 6 million people will have HIV by the year 2000, with more than 70% of recorded HIV transmissions in the region occurring through unprotected sex. AIDS, however, in many areas is considered to be an alien or foreign disease. More than almost any other disease, AIDS has generated myths and wild theories about its origin, causes, and existence. A new report published by the World Health Organization has pointed out that incorrect information, ignorance, and cultural practices complicate anti-AIDS campaign efforts in many countries. Difficult though it may be, it is important that the right information is disseminated in developing Asia to help the campaign against AIDS. Asia is the world's most populous continent and the region which experts say will be the locus of the disease's spread by the end of the century.

AID pulse generator monitors the heart continuously, recognizes onset of fibrillation, then administers a corrective electrical shock. A mini- computer, a power source, and two electrodes which sense heart activity are included in the unit. An associated system was also developed. It includes an external recorder to be worn by AID patients and a physician's console to display the data stored by the recorder. System provides a record of fibrillation occurrences and the ensuing defibrillation.

  7. AIDS in Africa: a political overview.

    In examining the spread of AIDS throughout Africa, it is important to recognize the differential factors of geography, economics, politics and other sociodemographic factors. Many factors such as increased prostitution and the presence of socially sanctioned promiscuity in certain communities have helped to accelerate the spread of AIDS. Statistics show that the epidemic is affecting larger numbers and is demanding recognition by political and medical authorities. Between the years 1987 and 1988, the number of AIDS cases in Uganda quadrupled. A hospital in Zaire reported that 1/4 of all deaths recorded in its facility were AIDS related. In certain sections of Central and East Africa, 2-15% of pregnant women are HIV-positive. Poor coping systems and weakened economies have prevented countries from instituting expensive health education programs. Other countries hoping to combat the epidemic might replicate the efforts of Ugandans who have worked diligently to distribute 3 million leaflets of information and open 13 screening centers. It is recognized that the AIDS epidemic will negatively affect Africa's workforce, the combined economies of African nations, and social conditions. Research in the areas of population movements and social practices is crucial to forecast the patterns of the epidemic is needed. Western aid in research and educational activities is also important in Africa's battle against AIDS.

    We developed two weight-length models from 231 populations of larval sea lampreys (Petromyzon marinus) collected from tributaries of the Great Lakes: Lake Ontario (21), Lake Erie (6), Lake Huron (67), Lake Michigan (76), and Lake Superior (61). Both models were mixed models, which used population as a random effect and additional environmental factors as fixed effects. We resampled weights and lengths 1,000 times from data collected in each of 14 other populations not used to develop the models, obtaining a weight and length distribution from reach resampling. To test model performance, we applied the two weight-length models to the resampled length distributions and calculated the predicted mean weights. We also calculated the observed mean weight for each resampling and for each of the original 14 data sets. When the average of predicted means was compared to means from the original data in each stream, inclusion of environmental factors did not consistently improve the performance of the weight-length model. We estimated the variance associated with measures of abundance and mean weight for each of the 14 selected populations and determined that a conservative estimate of the proportional contribution to variance associated with estimating abundance accounted for 32% to 95% of the variance (mean = 66%). Variability in the biomass estimate appears more affected by variability in estimating abundance than in converting length to weight. Hence, efforts to improve the precision of biomass estimates would be aided most by reducing the variability associated with estimating abundance.

    Progress in hearing aids has come a long way. Yet despite such progress hearing aids are not the perfect answer to many hearing problems. Some adult ears cannot accommodate tightly fitting hearing aids. Mouth movements such as chewing, talking, and athletic or other active endeavors also lead to loosely fitting ear molds. It is well accepted that loosely fitting hearing aids are the cause of feedback noise. Since feedback noise is the most common complaint of hearing aid wearers it has been the subject of various patents. Herein a hearing aid assembly is provided eliminating feedback noise. The assembly includes the combination of a hearing aid with a headset developed to constrict feedback noise.

    / Environmental regulatory agencies are responsible for protecting human health and the environment in their constituencies. Their responsibilities include the identification, evaluation, and cleanup of contaminated sites. Leaking underground storage tanks (USTs) constitute a major source of subsurface and groundwater contamination. A significant portion of a regulatory body's efforts may be directed toward the management of UST-contaminated sites. In order to manage remedial sites effectively, vast quantities of information must be maintained, including analytical dataon chemical contaminants, remedial design features, and performance details. Currently, most regulatory agencies maintain such information manually. This makes it difficult to manage the data effectively. Some agencies have introduced automated record-keeping systems. However, the ad hoc approach in these endeavors makes it difficult to efficiently analyze, disseminate, and utilize the data. This paper identifies the information requirements for UST-contaminated site management at the Waste Cleanup Section of the Department of Environmental Resources Management in Dade County, Florida. It presents a viable design for an information management system to meet these requirements. The proposed solution is based on a back-end relational database management system with relevant tools for sophisticated data analysis and data mining. The database is designed with all tables in the third normal form to ensure data integrity, flexible access, and efficient query processing. In addition to all standard reports required by the agency, the system provides answers to ad hoc queries that are typically difficult to answer under the existing system. The database also serves as a repository of information for a decision support system to aid engineering design and risk analysis. The system may be integrated with a geographic information system for effective presentation and dissemination of spatial data.

    Worldwide, there is a consensus that parents must be involved in children's HIV/AIDS education. However, there is little evidence that speaks to this advocacy for improving adolescent health. This study developed and tested four hypotheses about (i) the relationship between parents' and adolescents' knowledge of HIV/AIDS transmission routes and prevention strategies conditional upon (ii) parents' gender, (iii) communication about sexuality, and (iv) the parent-adolescent education gap. The sample consisted of 306 parent-adolescent dyads from the 2002 Cameroon Family and Health Survey. Adolescents were aged 12-19 years. Overall, fifteen items about HIV/AIDS transmission routes and prevention strategies were analysed. Descriptive results showed that parents fared better than adolescents regardless of the AIDS fact considered. An exception was the correct use of condoms (parents 57% vs adolescents 61%). The generation gap probably explains this result: parents are more conservative, reluctant and distant from condoms compared with adolescents, who are more receptive and open to discussing sex with peers. Multivariate ordered logistic regressions showed a significant positive effect of parents' HIV/AIDS knowledge on adolescents' HIV/AIDS knowledge, thus supporting the main hypothesis of direct parental influences. Parent-adolescent communication about sexuality showed positive and significant effects on adolescents' HIV/AIDS knowledge, suggesting an 'enhancing effect' when combined with the effect of parents' HIV/AIDS knowledge. Against the background that parents in sub-Saharan Africa do not teach their children about sexuality, the study demonstrated that families can play an important role in HIV/AIDS education. These findings have major implications for HIV/AIDS interventions involving adolescents, parents or both, in fostering accurate HIV/AIDS knowledge among adolescents, which could lead to protective sexual behaviours.

    Recent estimates reaffirm that conservation funds are insufficient to meet biodiversity conservation goals. Organisations focused on biodiversity conservation therefore need to capitalise on investments that societies make in environmental protection that provide ancillary benefits to biodiversity. Here, we undertake the first assessment of the potential ancillary benefits from the ballot box in the United States, where citizens vote on referenda to conserve lands for reasons that may not include biodiversity directly but that indirectly might enhance biodiversity conservation. Our results suggest that referenda occur in counties with significantly greater biodiversity than counties chosen at random. We also demonstrate that large potential gains for conservation are possible if the past and likely future outcomes of these ballot box measures are directly incorporated into national-scale conservation planning efforts. The possible synergies between ballot box measures and other biodiversity conservation efforts offer an under-utilised resource for supporting conservation.

  15. Water Conservation and Water Storage

    2014-12-01

    Water storage can be a viable part of the solution to water conservation. This means that we should include reservoirs. Regardless, one should evaluate all aspects of water conservation principles. Recent drought in California indicates that there is an urgent need to re-visit the techniques used to maintain the water supply-chain mechanism in the entire state. We all recognize the fact that fish and wildlife depend on the streams, rivers and wetlands for survival. It is a well-known fact that there is an immediate need to provide solid protection to all these resources. Laws and regulations should help meet the needs of natural systems. Farmers may be forced to drilling wells deeper than ever. But, they will be eventually depleting groundwater reserves. Needless to say that birds, fish and wildlife cannot access these groundwater table. California is talking a lot about conservation. Unfortunately, the conservation efforts have not established a strong visible hold. The Environmental Protection Agency has a plan called E2PLAN (Narayanan, 2012). It is EPA's plan for achieving energy and environmental performance, leadership, accountability, and carbon neutrality. In June 2011, the EPA published a comprehensive, multi-year planning document called Strategic Sustainability Performance Plan. The author has previously reported these in detail at the 2012 AGU fall meeting. References: Ziegler, Jay (15 JUNE 2014).

  16. Rain Hampers Tsunami Relief Efforts

    2005-01-01

    The cleanup and relief efforts from the recent tsunamis continue in coastal communities that were ravaged by the waves all across the Indian Ocean. Heavy rains have further complicated the matter and added to the misery in parts of eastern Sri Lanka. Between December 28, 2004, and January 5, 2005, up to 10 to 15 inches of rain may have fallen along the southeast coast of the island, and as much as 20 inches (red areas) fell just offshore. This rainfall map was created by the TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center, which monitors rainfall over the global tropics. The map shows that many other regions around the Indian Ocean were also affected by the rains, including Malaysia and parts of Sumatra. The heaviest rains fell on December 31 and January 4. The rains were likely the result of a combination of the northeast monsoon interacting with the topography and an active phase of what is known as the Madden-Julian Oscillation (MJO) (or 30-60 day oscillation). The MJO is a large-scale disturbance that propagates eastward from the Indian Ocean into the West Pacific Ocean, bringing extended periods of unsettled weather with it. Individual convective complexes within the MJO can last on the order of a day. TRMM is a joint mission between NASA and the Japanese space agency JAXA.

  17. Rethinking Ginkgo biloba L.: Medicinal uses and conservation

    PubMed Central

    Isah, Tasiu

    2015-01-01

    Ginkgo biloba (G. biloba) is an ancient medicinal tree species that has been in existence for millennia without undergoing modifications due to its resistance to environmental stresses. Palaeobotanical history showed a wide distribution of the species across the globe but declined over geological time, becoming restricted to narrow geographical range with few surviving individuals in the modern day. The tree is slow growing, adapted to many ecological conditions and shows numerous adaptation in developmental patterns. Medicinal use of the species is attracting research interest, especially the various parts of the tree that are used in orthodox or traditional medicine to treat diseases due to the many bioactive compounds. The primary compounds receiving increasing research interest are the triterpene lactones and flavonoids; these are the target of biotechnological strategies being employed to enhance production. Many genetic and environmental factors have contributed to the endangered status of the species; conservation measures are required to protect it from extinction. In many countries, the cultivation of plantations for the supply of ginkgo leaf-based pharmaceutical formulations is in progress, and efforts to standardize ginkgo leaf extract as herbal medication for human use are being made. Microcuttings and cuttings, cryopreservation, and plant tissue culture have all aided to conserve G. biloba. PMID:26392712

    We have developed a web application for the detailed analysis and visualization of evolutionary sequence conservation in complex vertebrate genes. Given a pair of orthologous genes, the protein-coding sequences are aligned. When these sequences are mapped back onto their encoding exons in the genomes, a scaffold of the conserved gene structure naturally emerges. Sequence similarity between exons and introns is analysed and embedded into the gene structure scaffold. The visualization on the SVC server provides detailed information about evolutionarily conserved features of these genes. It further allows concise representation of complex splice patterns in the context of evolutionary conservation. A particular application of our tool arises from the fact that around mRNA editing sites both exonic and intronic sequences are highly conserved. This aids in delineation of these sites. SVC is available at http://svc.molgen.mpg.de.

    Acquired immune deficiency syndrome (AIDS) has been an African and Western concern due to its epidemic nature. Although nearly 99% of all reported cases occurred in these regions, Asia has reported cases, and the potential for devastation of Asia's already strained health care reserves are undeniable. This review compiled by analysis of 1986-88 articles on AIDS research, demographics, official statements from government and health organizations, news reports, and public statements describe how AIDS has spread in well documented regions like America, Europe, and Africa, and how the Asian regions have attempted to handle the AIDS epidemic before it becomes as serious as in the West. The topics covered include a clinical overview of how human immunodeficiency virus (HIV) causes AIDS, how it is transmitted, and what are the primary forms of transmission in well documented regions. The report briefly documents what policies China, Hong Kong, Japan, Republic of Korea, Taiwan, Philippines, Thailand, Singapore, Malaysia, Indonesia, India, Sri Lanka, Bangladesh, Nepal, Pakistan, Australia, and New Zealand have individually instituted to stem the flow of AIDS into their country, and/or stop the spread of AIDS already found there. The efforts to combat AIDS globally by the World Health Organization/United Nations Development Program alliance (WHO-UNDP) along with the US Agency for International Development (USAID), and UNICEF are highlighted. The available research and aid programs are contrasted with how the Asian nations are preparing to deal with the AIDS epidemic. 1) AIDS has an incubation time wherein an infected individual is not AIDS symptomatic, but is capable of infecting others, and this hidden infected population makes it essential that containment policies are also enforced in countries with few reported cases. 2) A committee should be established in all Asian countries to coordinate education on safe sexual behaviors with specific programs for prostitutes

    The story of sea otters over the past 275 years chronicles their decline to near extinction and the roads to recovery that cross various conflicts, and in the end provides lessons that will aid the conservation of other threatened species and compromised ecosystems. Sea otters inspire strong human emotions ranging from adoration to disdain. They are protected internationally, federally, and at state and local levels, yet still face a diversity of threats, representing the legacy of their decline as well as emerging consequences from the ever-deepening imprint of the human endeavor. Here we briefly introduce the species, chronicle its history of near-demise and subsequent recovery, and highlight several conservation successes and challenges. In this volume we bring together scientists with significant knowledge of and experience with the sea otter and its ecosystems to share lessons learned and consider how these might be used to aid in the enterprise of conservation more broadly.

  8. International population assistance: a spur to national effort.

    PubMed

    Salas, R M

    1974-01-01

    A continuing role for multilateral assitance in population will exist. Only international organizations can adequately transmit information, provide multinational experts and transmit certain technical advances in the population field. Aid-receiving countries must show both the realistic and necessary objectives and the will to execute their plans. A serious concern of aid administrators today is the probability that the volume of development assistance which showed an accelerated rate of increase in its early years is indefinitely at a plateau. Many varied reasons for this exist including the sharp, troublesome changes in world trade patterns, a crescendo of accusations of ineffective aid and a very slow rise, if any, in net per capita production. Aid-receiving countries have been discontent because of tied loans and allegations that aid has had inflationary results. Unlike other development projects, population programs often take a generation or more to take full effect. It is sometimes claimed that rapid population growth is the single most important obstacle to improved living standards. This opinion is not universally agreed on, however. Other possible obstacles are neglect of agriculture, lack of adequate infrastructure to develop markets and rigid social structures. A reduction in the population growth rate may actually be a serious hindrance to the attainment of economic and social goals. International assistance has only been a marginal addition to the total development resources of aid-receiving countries, although it has made a major contribution to the initial implementation of population programs, especially in India and China. Aid should be given in those basic areas which will yield better returns in the long run. It should be a 'spur' rather than a catalyst, which is only effective in a short-term crisis. The main aim is the creation of clear national population goals toward which the nation's human resources should be mobilized according to its

    PubMed

    Krieger, N

    1988-01-01

    Despite the Department of Health and Human Service's 1983 claim that AIDS is the nation's "number one health priority," funding for AIDS research, prevention, and treatment remains inadequate. Worse, it is often marshaled from or juxtaposed against other necessary health allocations. Consequent AIDS-related resource crises include diverting funds for research on other diseases to AIDS investigations, propping up AIDS prevention efforts at the expense of traditional sexually transmitted disease control programs, and pitting the health needs of AIDS patients against the needs of those seeking other urgent health services, e.g., prenatal care. While this forced competition typically is blamed on fiscal constraints, examination of federal spending priorities suggests that it results principally from Reagan Administration policies. This Administration has consistently boosted military spending at the expense of social and health services, and has deliberately undermined efforts to obtain sufficient and new allocations for AIDS. In order to avert political divisions spurred by competition for currently scarce resources, AIDS and other health activists together must argue that excessive military allocations must be shifted to health research and services, and that a national health program must be implemented, if AIDS programs are to be funded appropriately without jeopardizing other necessary health initiatives.

    The signal processing and fitting methods used for hearing aids have mainly been designed to optimize the intelligibility of speech. Little attention has been paid to the effectiveness of hearing aids for listening to music. Perhaps as a consequence, many hearing-aid users complain that they are not satisfied with their hearing aids when listening to music. This issue inspired the Internet-based survey presented here. The survey was designed to identify the nature and prevalence of problems associated with listening to live and reproduced music with hearing aids. Responses from 523 hearing-aid users to 21 multiple-choice questions are presented and analyzed, and the relationships between responses to questions regarding music and questions concerned with information about the respondents, their hearing aids, and their hearing loss are described. Large proportions of the respondents reported that they found their hearing aids to be helpful for listening to both live and reproduced music, although less so for the former. The survey also identified problems such as distortion, acoustic feedback, insufficient or excessive gain, unbalanced frequency response, and reduced tone quality. The results indicate that the enjoyment of listening to music with hearing aids could be improved by an increase of the input and output dynamic range, extension of the low-frequency response, and improvement of feedback cancellation and automatic gain control systems.

Spiers, a founding member of ACT UP, discusses the rationale behind the tactics of civil disobedience employed by AIDS activists. He argues that civil disobedience is justified by American political and legal traditions, and by the federal government's lack of response to the needs of its citizens. Spiers warns that while AIDS protests have been nonviolent and characterized by conscientious planning and execution, violence cannot be ruled out as a "political act born of desperation."

    In order to provide comprehensive care to patients who have AIDS, it is important for the family physician to understand the psychosocial elements of the disease. Homosexual men who have AIDS face particular problems, such as the disclosure of sexual orientation to family and friends. Issues discussed in this article include the reactions of the patient, family and friends to the diagnosis, the stigma of AIDS, the patient's support network, and preparations for disability and death. The facts about AIDS are discussed briefly, and the psychosocial implications of the illness for patients and their “significant others” are examined. The role of the family physician is highlighted.

    Activation-induced cytidine deaminase (AID) is expressed in a B cell differentiation stage-specific fashion and is essential for immunoglobulin (Ig) gene class switch DNA recombination (CSR) and somatic hypermutation (SHM). CSR and SHM play a central role in the maturation of antibody and autoantibody responses. AID displays a mutagenic activity by catalyzing targeted deamination of deoxycytidine (dC) residues in DNA resulting in dU:dG mismatches, which are processed into point-mutations in SHM or double-strand breaks (DSBs) in CSR. Although AID specifically targets the Ig gene loci (IgH, Igκ and Igλ), it can also home into a wide array of non-Ig genes in B-and non-B-cell backgrounds. Aberrant expression of AID is associated with multiple diseases such as allergy, inflammation, autoimmunity and cancer. In autoimmune systemic lupus erythematosus, dysregulated AID expression underpins increased CSR, SHM and autoantibody production. As a potent mutator, AID is under stringent transcriptional, post-transcriptional and post-translational regulation. AID is also regulated in its targeting and enzymatic function. In resting naïve or memory B cells, AID transcripts and protein are undetectable. These, however, are readily and significantly up-regulated in B cells induced to undergo CSR and/or SHM. Transcription factors, such as HoxC4 and NF-κB, which are up-regulated in a B cell lineage-and/or differentiation stage-specific manner, regulate the induction of AID. HoxC4 induces AID expression by directly binding to the AID gene promoter through an evolutionarily conserved 5'-ATTT-3' motif. HoxC4 is induced by the same stimuli that induce AID and CSR. It is further up-regulated by estrogen through three estrogen responsive elements in its promoter region. The targeting of AID to switch (S) regions is mediated by 14-3-3 adaptor proteins, which specifically bind to 5'-AGCT-3' repeats that are exist at high frequency in S region cores. Like HoxC4, 14-3-3 adaptors are induced

  18. AIDS is your business.

    If your company operates in a developing country, AIDS is your business. While Africa has received the most attention, AIDS is also spreading swiftly in other parts of the world. Russia and Ukraine had the fastest-growing epidemics last year, and many experts believe China and India will suffer the next tidal wave of infection. Why should executives be concerned about AIDS? Because it is destroying the twin rationales of globalization strategy-cheap labor and fast-growing markets--in countries where people are heavily affected by the epidemic. Fortunately, investments in programs that prevent infection and provide treatment for employees who have HIV/AIDS are profitable for many businesses--that is, they lead to savings that outweigh the programs' costs. Due to the long latency period between HIV infection and the onset of AIDS symptoms, a company is not likely to see any of the costs of HIV/AIDS until five to ten years after an employee is infected. But executives can calculate the present value of epidemic-related costs by using the discount rate to weigh each cost according to its expected timing. That allows companies to think about expenses on HIV/AIDS prevention and treatment programs as investments rather than merely as costs. The authors found that the annual cost of AIDS to six corporations in South Africa and Botswana ranged from 0.4% to 5.9% of the wage bill. All six companies would have earned positive returns on their investments if they had provided employees with free treatment for HIV/AIDS in the form of highly active antiretroviral therapy (HAART), according to the mathematical model the authors used. The annual reduction in the AIDS "tax" would have been as much as 40.4%. The authors' conclusion? Fighting AIDS not only helps those infected; it also makes good business sense. PMID:12577655

    Bogota, Colombia, is the third highest capital in South America, its location near the equator assures high altitudes over the horizon and almost 5 hours of daily mean sunshine. Since 1981, efforts for using natural energy instead of nonrenewable fuel have been targeted to Colombia`s residential construction industry. This paper focuses on a computer aided design process for passive solar low-income row housing in Bogota. Thermal comfort for this tropical climate has been achieved through employing ``Guadua,`` a strong bamboo specie,as an alternative wall system to the traditional brick, adobe, or concrete structures. Through computer analysis, several energy conservation and passive solar strategies have been optimized for a case study row housing type common to the region. The load savings compared to a 6 inch CMU house totaled 72%, while the operating cost has been reduced by 71%. Furthermore, this lightweight and inexpensive ``Guadua`` material has reduced the construction cost by 30%.

  20. Evaluating Local Benefits from Conservation in Nepal's Annapurna Conservation Area

    Protected areas are integral to the global effort to conserve biodiversity, and, over the past two decades, protected area managers have begun to recognize that conservation objectives are next to impossible to achieve without considering the needs and concerns of local communities. Incentive-based programs (IBPs) have become a favored approach to protected area management, geared at fostering local stewardship by delivering benefits tied to conservation to local people. Effective IBPs require benefits to accrue to and be recognized by those experiencing the greatest consequences as a result of the protected area, and those likely to continue extractive activities if their livelihood needs are compromised. This research examines dispersal of IBP benefits, as perceived by local residents in Nepal’s Annapurna Conservation Area. Results reported here are based on questionnaire interviews with 188 households conducted between September and December 2004. Results indicate that local residents primarily identify benefits from social development activities, provisions for resource extraction, and economic opportunities. Overall, benefits have been dispersed equally to households in villages on and off the main tourist route, and regardless of a household’s participation in tourism. However, benefits are not effectively targeted to poorer residents, those highly dependent on natural resources, and those experiencing the most crop damage and livestock loss from protected wildlife. This article provides several suggestions for improving the delivery of conservation incentives.

  11. AIDS: an economic perspective.

    Squire, L

    1998-08-01

    Each country currently experiencing an AIDS epidemic did not believe that the epidemics would develop, but they did and more than 6 million people have since died. However, if the governments of the approximately 2.3 billion people who live in developing countries where HIV/AIDS has not yet spread to the general population, together with the international community and nongovernmental organizations, act promptly, many lives will be saved. The World Bank publication "Confronting AIDS: Public Priorities in a Global Epidemic" brings, for the first time, an economic perspective to the problem of AIDS. The author considers how developing country governments should respond to the AIDS epidemic when they also face so many other major and pressing problems related to raising more than 1 billion people out of severe poverty. While AIDS is an important problem which must be immediately addressed, using resources to help people with AIDS will come at the expense of other objectives such as sending children to school, providing safe drinking water, and building infrastructure. The serious nature of the HIV/AIDS epidemic and what governments should do are considered. PMID:12294026

    So far, AIDS has not been a major problem in Taiwan. Only 79 people have tested HIV-seropositive, and only 6 have been stricken by the disease. The government has allocated money for AIDS research; blood screening is mandatory in all hospitals; confidential AIDS testing is widely available; and doctors are advised to administer azidothymidine to anyone who tests positive. Azidothymidine is not a cure, but it can prevent the virus from destroying more cells. Nevertheless, a climate of irrational fear of and ignorance about AIDS pervades Taiwan. Many people believe that AIDS can be transmitted by casual contact, and people who are HIV-seropositive are treated as social outcasts. One student at the University of Taipei, only a few credits from graduation, has been refused readmission to the university because he tested HIV-positive. Sex education in the schools is not a good route for AIDS education because sex and especially homosexuality are simply not mentioned in public in Taiwan. Activists, including gay-rights representative, Chi Chia-Wei, have turned to the mass media, especially television as a vehicle for AIDS education, and several programs on AIDS have been shown since 1986.

    1997-01-01

    The focus of the 1997 World AIDS Day was children. An estimated 1600 children become infected with HIV each day and, by the end of 1997, 1 million children--95% of them in developing countries--are expected to be HIV-infected. Another 8 million children have lost their mothers to AIDS. Although most HIV-positive children become infected as a result of maternal-child transmission during pregnancy, childbirth, and breast feeding, other risk factors such as child sex abuse, exploitation in the commercial sex trade, blood transfusions, and intravenous drug use are also significant in later years. Because of its devastating impact on social and economic life, the fight against AIDS is one of the most important challenges in the world today. The UNAIDS program, a joint venture of 6 UN agencies with expertise ranging from reproductive health care to economic development, is at the center of this effort.

  20. Mass media entertainment for AIDS communication in Zaire.

    Convisser, J

    1992-01-01

    Health communicators use entertainment and mass media to prevent HIV transmission. Population Services International operates an AIDS Mass Media Project as an adjunct to its Condom Social Marketing Project. It collaborates with the Government of Zaire's National AIDS Program. Its 1st target is urban youth because most AIDS cases in Zaire were infected as teenagers, urban youth have access to television (TV), and they take part in high risk sexual behavior. The project uses various AIDS songs to reach this group. A 6-month posttest shows that the 1st song was so effective that 65% heard it and that 93% of them recalled the major AIDS messages and 85% said that they changed their behavior. The project distributes a video of the 1990 World AIDS Day concert. Research in Zaire and other African countries shows that the threat AIDS poses to children's health strongly motivates parents' behavior. Thus the 2nd target is the 20-30 year old group--young and prospective parents. The project boasts a 4-part TV series about a groom who does not reveal his AIDS status to his young bride until after their wedding night. 2 scenes stress the benefits of condoms. After its 1st airing, 66% of the 20-30 year old group in Kinshasa watched all 4 parts of the series. Of these, about 75% said they would change their behavior. Most people in Zaire change behavior by using condoms. Indeed, during the mass media campaign, condom sales grew 1000% which saved almost 7200 lives. The project also features comic strips informing working men and women and teenagers about AIDS and distributes an inexpensive notebook listening AIDS facts and myths for school children. The project uses regional radio stations to broadcast 28 AIDS feature programs, 22 radio spots, 8 AIDS radio dramas, and 2 songs to high priority rural areas. These AIDS radio efforts have indeed influenced AIDS knowledge and attitudes. PMID:12285440

    The acquired immune deficiency syndrome (AIDS) is a harbinger for change in health care. There are many powerful forces poised to transform the industrialized health care structure of the twentieth century, and AIDS may act as either a catalyst or an amplifier for these forces. AIDS could, for example, swamp local resources and thereby help trigger national reform in a health care system that has already lost public confidence. AIDS can also hasten the paradigm shift that is occurring throughout health care. Many of the choices society will confront when dealing with AIDS carry implications beyond health care. Information about who has the disease, for example, already pits traditional individual rights against group interests. Future information systems could make discrimination based upon medical records a nightmare for a growing number of individuals. Yet these systems also offer the hope of accelerated progress against not only AIDS but other major health threats as well. The policy choices that will define society's response to AIDS can best be made in the context of a clearly articulated vision of a society that reflects our deepest values. PMID:10119289

    Forsythe, S

    1999-01-01

    Since it tends to be significantly affected by HIV/AIDS, the tourism sector is a likely target for HIV/AIDS interventions in many countries. The tourist industry is at particular risk from the pandemic because of the mobility of the work force, the presence of sex tourists, and the heavy reliance of many countries upon tourism revenues. Indeed, tourism is one of the largest and fastest growing industries in many countries. Some people have speculated that potential tourists' fear of AIDS could discourage them from visiting certain countries, while others have even suggested that tourism should be discouraged because the industry contributes to the spread of HIV/AIDS. When traveling, tourists often take risks that they would not take at home. They tend to drink more, use drugs more, and be generally more adventurous while on holiday. Such adventures often include taking sexual risks. When tourists have sex with prostitutes, hotel staff, and others in the local population, a bridge can be created for HIV to cross back and forth between the tourist's home country and the tourist destination. The author reviews selected studies on the relationship between HIV/AIDS and tourism. Overall, the existing literature offers no definitive evidence that AIDS has had any lasting impact upon the tourism industry anywhere in the world. Rather, promoting a healthy tourism industry and HIV/AIDS prevention are likely complementary in many ways. PMID:12349153

    Historically, the primary concern for hearing aid design and fitting is optimization for speech inputs. However, increasingly other types of inputs are being investigated and this is certainly the case for music. Whether the hearing aid wearer is a musician or merely someone who likes to listen to music, the electronic and electro-acoustic parameters described can be optimized for music as well as for speech. That is, a hearing aid optimally set for music can be optimally set for speech, even though the converse is not necessarily true. Similarities and differences between speech and music as inputs to a hearing aid are described. Many of these lead to the specification of a set of optimal electro-acoustic characteristics. Parameters such as the peak input-limiting level, compression issues—both compression ratio and knee-points—and number of channels all can deleteriously affect music perception through hearing aids. In other cases, it is not clear how to set other parameters such as noise reduction and feedback control mechanisms. Regardless of the existence of a “music program,” unless the various electro-acoustic parameters are available in a hearing aid, music fidelity will almost always be less than optimal. There are many unanswered questions and hypotheses in this area. Future research by engineers, researchers, clinicians, and musicians will aid in the clarification of these questions and their ultimate solutions. PMID:15497032

  6. Solidarity and AIDS: introduction.

    PubMed

    Krieger, N

    1991-01-01

    Perhaps more than any other disease in recent history, AIDS has taught a cruel and crucial lesson: the constraints on our response to this epidemic are as deep as our denial, as entrenched as the inequities that permeate our society, as circumscribed as our knowledge, and as unlimited as our compassion and our commitment to human rights. Elaborating on these themes, the final three articles in this Special Section on AIDS consider three widely divergent yet intimately connected topics: AIDS in Cuba, AIDS in Brazil, and global AIDS prevention in the 1990s. Together, they caution that if we persist in treating AIDS as a problem only of "others," no country will be spared the social and economic devastation that promises to be the cost of our contempt and our folly. Solidarity is not an option; it is a necessity. Without conscious recognition of the worldwide relationship between health, human rights, and social inequalities, our attempts to abate the spread of AIDS--and to ease the suffering that follows in its wake--most surely will fall short of our goals. Finally, as we mourn our dead, we must take to heart the words of Mother Jones, and "fight like hell for living." This is the politics of survival.

    1987-01-01

    The incidence of AIDS in Latina women is over 11 times that of white women. Women account for 13% of all Latino AIDS deaths since 1980. This examination of the impact of AIDS on Latino women concentrates on Manhattan's Lower East Side. The AIDS deaths among Puerto Rican women in this neighborhood are predominantly intravenous drug abuse related. Latina women accounted for more than 1/2 of all female AIDS deaths on the Lower East Side during the 1980-1985 period. The age range is parallel with that in the rest of New York City, with the exception of a higher number of deaths on the Lower East Side in the age ranges of 15-19 and over 40. Serious obstacles exist to providing AIDS risk reduction information to Puerto Rican women and their partners. Latinos account for 11% of all US AIDS cases among gay and bisexual men. The cultural proscription against these sexual practices in the Puerto Rican community makes AIDS education related to such practices extremely difficult. Many of the female sex partners of these men are unaware of their bisexuality, and, therefore not aware that they are at risk of HIV infection. The Latina women most at risk are young, poor, and have low educational levels. Latina women seriously underutilize ongoing primary health care, family planning, prenatal or pediatric care. Attempts to reach Latina women with AIDS risk reduction education must also contend with issues such as cultural gender roles. Females tend to be dependent on males and defer to male decision making related to sexual practices. In formulating policy regarding services and education, it is essential to involve the leadership of the Latino community. PMID:12268416

    This paper reports on the 1996 South African Universities Social Sciences Conference on AIDS held in Mmambatho, Northwest Province, South Africa. The conference was attended with a strong contingent from Botswana, Lesotho, Malawi, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe. In the conference, various papers explored the needs of, and programmatic responses to women, orphaned children, university students, communities, youth private enterprise, the informal sector, and policy and socioeconomic concerns at a broader level. In addition, several papers specifically discussed the situation of women and AIDS, as well as relevant policy issues. A recommendation was made for governments to coordinate their efforts, with a call for increased openness at all levels rather than facing the epidemic individually. In this respect, the conference noted that the media could play a much more decisive role. This report also highlights the major comments made during the conference and some of the key issues that were raised in each of the following areas: 1) awareness and prevention, 2) children, 3) women, and 4) household costs.

    2014-01-01

    In this study, we explored the multifaceted concept of perceived mental and physical effort in team sport contexts where athletes must invest individual and shared efforts to reach a common goal. Semi-structured interviews were conducted with a convenience sample of 15 Catalan professional coaches (3 women and 12 men, 3 each from the following sports: volleyball, basketball, handball, soccer, and water polo) to gain their views of three perceived effort-related dimensions: physical, psychological, and tactical. From a theoretical thematic analysis, it was found that the perception of effort is closely related to how effort is distributed within the team. Moreover, coaches viewed physical effort in relation to the frequency and intensity of the players' involvement in the game. They identified psychological effort in situations where players pay attention to proper cues, and manage emotions under difficult circumstances. Tactical effort addressed the decision-making process of players and how they fulfilled their roles while taking into account the actions of their teammates and opponents. Based on these findings, a model of perceived distributed effort was developed, which delineates the elements that compose each of the aforementioned dimensions. Implications of perceived distributed effort in team coordination and shared mental models are discussed. PMID:24404807

Semi-structured interviews were conducted with a convenience sample of 15 Catalan professional coaches (3 women and 12 men, 3 each from the following sports: volleyball, basketball, handball, soccer, and water polo) to gain their views of three perceived effort-related dimensions: physical, psychological, and tactical. From a theoretical thematic analysis, it was found that the perception of effort is closely related to how effort is distributed within the team. Moreover, coaches viewed physical effort in relation to the frequency and intensity of the players' involvement in the game. They identified psychological effort in situations where players pay attention to proper cues, and manage emotions under difficult circumstances. Tactical effort addressed the decision-making process of players and how they fulfilled their roles while taking into account the actions of their teammates and opponents. Based on these findings, a model of perceived distributed effort was developed, which delineates the elements that compose each of the aforementioned dimensions. Implications of perceived distributed effort in team coordination and shared mental models are discussed.

    Medrad utilized NASA's Apollo technology to develop a new device called the AID implantable automatic pulse generator which monitors the heart continuously, recognizes the onset of ventricular fibrillation and delivers a corrective electrical shock. AID pulse generator is, in effect, a miniaturized version of the defibrillator used by emergency squads and hospitals to restore rhythmic heartbeat after fibrillation, but has the unique advantage of being permanently available to the patient at risk. Once implanted, it needs no specially trained personnel or additional equipment. AID system consists of a microcomputer, a power source and two electrodes which sense heart activity.

    After briefly stating the significance of acquired immunodeficiency syndrome (AIDS) for public health, this paper considers programs or proposals to control the spread of AIDS in the following eight general areas: (a) education; (b) distribution of sterile needles; (c) screening and treatment of blood, blood products, and other tissues; (d) voluntary and mandatory screening of persons for evidence of infection; (e) reporting; (f) contact tracing; (g) isolation and other restrictions on freedom of movement or association; and (h) physical marking of persons with AIDS. Significant moral issues within each of these areas are discussed, and the overall justifiability of various proposals is examined.

  18. Brainstem Encoding of Aided Speech in Hearing Aid Users with Cochlear Dead Region(s)

    Introduction  Neural encoding of speech begins with the analysis of the signal as a whole broken down into its sinusoidal components in the cochlea, which has to be conserved up to the higher auditory centers. Some of these components target the dead regions of the cochlea causing little or no excitation. Measuring aided speech-evoked auditory brainstem response elicited by speech stimuli with different spectral maxima can give insight into the brainstem encoding of aided speech with spectral maxima at these dead regions. Objective  This research aims to study the impact of dead regions of the cochlea on speech processing at the brainstem level after a long period of hearing aid use. Methods  This study comprised 30 ears without dead regions and 46 ears with dead regions at low, mid, or high frequencies. For all ears, we measured the aided speech-evoked auditory brainstem response using speech stimuli of low, mid, and high spectral maxima. Results  Aided speech-evoked auditory brainstem response was producible in all subjects. Responses evoked by stimuli with spectral maxima at dead regions had longer latencies and smaller amplitudes when compared with the control group or the responses of other stimuli. Conclusion  The presence of cochlear dead regions affects brainstem encoding of speech with spectral maxima perpendicular to these regions. Brainstem neuroplasticity and the extrinsic redundancy of speech can minimize the impact of dead regions in chronic hearing aid users. PMID:27413404

    Fifty-two patients with pulmonary complications of acquired immunodeficiency syndrome (AIDS) were studied over a 3-year period. The vast majority of the patients were homosexual; however, a significant number were intravenous drug abusers. Thirteen different organisms were noted, of which Pneumocystis carinii was by far the most common. Five patients had neoplasia. Most patients had initial abnormal chest films; however, eight patients subsequently shown to have Pneumocystis carinii pneumonia had normal chest films. A significant overlap in chest radiographic findings was noted among patients with different or multiple organisms. Lung biopsy should be an early consideration for all patients with a clinical history consistent with the pulmonary complications of AIDS. Of the 52 patients, 41 had died by the time this report was completed.

    It has been claimed that with the aid of isokinetic trunk strength measuring devices it is possible to distinguish true muscular weakness from submaximal effort in the test. This proposition is based on the presumption that in the isokinetic trunk strength test identical performances can only be reproduced by maximal effort. The purpose of this study was to investigate whether it is possible to distinguish maximal effort from submaximal with the aid of the coefficient of variation (CV) in an isokinetic trunk muscle strength test. The study group included 35 (21 male and 14 female) subjects of whom 12 were healthy, 10 had a mild low-back pain and 13 had a more severe chronic low-back pain. The subjects performed five consecutive bendings both with maximal (100%) and submaximal (50%) efforts at a speed of 90 degrees/second. In maximal effort only healthy subjects reached an average level of CV close to 10% both in extension and in flexion. In the chronic low-back pain group the average CV was close to 20%. The difference in CV was statistically significant (p < 0.05-0.02) between the healthy and the chronic low-back pain subjects. In the submaximal effort all health groups had a CV of approximately 20% or more and no significant differences were found. The group of slightly variable measurements (CV = 11-20%) was remarkably large in both the maximal and submaximal effort. The results suggest that an effort with a CV of 11-20% cannot be classified as definitely submaximal or maximal. When the CV is less than 10% the effort can be fairly certainly classified as maximal.

    Pressures to create a profitable Third World market for Western drugs may have led to the suppression of acquired immunodeficiency syndrome (AIDS) treatments developed in Africa. Six years before four Western pharmaceutical companies announced the discovery of a three-drug regimen that appears to produce remission in some patients infected with human immunodeficiency virus (HIV), Ugandan physician Dr. Charles Ssali had developed a similar formulation. Beginning in 1989, Dr. Ssali gave HIV-infected patients at his Kampala clinic a preparation, Miriandina, containing 27 naturally occurring anti-oxidants and micronutrients that stimulate the immune system and prevent progression to AIDS. To date, he has treated over 12,000 patients, with an 80% success rate. His first patient, who presented in 1989 with full-blown AIDS, is alive and symptom-free. Miriandina is taken for 12-18 months, at a cost of only US $0.50 per tablet ($600 for six months of treatment). Another herbal formulation, Pearl Omega, developed by scientist Arthur Obel with funds provided by the Kenyan government, has produced a similar reversal of AIDS symptoms. However, international donor organizations and the AIDS establishment have refused to fund these African-based efforts or to publicize their success. It is suggested that this reflects a plan to force African countries to take out World Bank loans to finance the more expensive ($8300 a course) Western-based protease inhibitors.

    AIDS surveillance data from the Dominican Republic are described for 1983-89. A positive serologic test for HIV was required, and standard clinical criteria were used for defining AIDS. There were 1,202 AIDS cases (820 men, 372 women, 10 of unknown gender) reported to the Ministry of Health, for a cumulative case rate of 17 per 100,000 persons. Rapid growth of the epidemic is noted, with 43% of the total cases reported in 1989. Heterosexual exposure accounts for 53% (593) of all cases, with a male-to-female ratio of 2.2:1, resembling a World Health Organization Pattern I/II country. Prevalence is highest in and surrounding the urbanized tourist areas of Santo Domingo and Puerto Plata and in districts with a high concentration of sugar plantation barracks, where laborers from Haiti and the Dominican Republic work and live. The distribution of AIDS cases is described by transmission exposure category, age, sex, year of diagnosis, and district. The National AIDS Surveillance Program can be improved by validation of exposure transmission categories through selected case investigation and by better reporting through training of health care providers. Surveillance data will assist in targeting future public health efforts to regions and persons at highest risk.

    The World Health Organization's Global Programme on AIDS (GPA)has organized HIV/AIDS surveillance systems worldwide and has analyzed and interpreted global trends of the pandemic. With 4.5 million cases of AIDS estimated by the middle of 1995 and a further 14-15 million adults believed to be infected with HIV, the epidemic continues to evolve. Not only is it spreading geographically into western and southern Africa, India, and other Asian countries, the number of women infected has risen to narrow the gap between the sexes. This increase in AIDS among women has led to a tandem increase in the number of mother-to-child transmissions of HIV. In some populations, however, prevalence appears to be stabilizing (among pregnant women in southern Zaire, in parts of Uganda, among military recruits in Thailand, in Australia, in northern Europe, in the US, and in Canada). This stabilization is partly due to prevention efforts. Proper surveillance is necessary to shed light on such hopeful signs and to discern their cause. Thus, the GPA will shortly publish country-specific estimates of HIV prevalence to insure that adequate prevention and care programs are instituted and to act as a monitoring tool. The GPA's prototype HIV incidence model can aid understanding of underlying trends when it is linked with surveillance data. Such a model can also allow measurements of the potential impact of vaccines when administered according to various vaccination strategies.

    Americans are looking for more-efficient ways to live and conduct their business without lowering their living standard. New building designs, intensive gardening, new energy sources, and vanpooling are among the pioneering efforts. Conservation also requires innovative ways to raise capital to handle nontraditional projects. A new industry of house doctors audits the energy efficiency of buildings and creates more-conserving designs and materials. Other industries will develop renewable and synthetic energy sources. Reports of changing attitudes and a growing interest in decentralized energy management are signs that conservation can become a way of life. (DCK)

    State wildlife conservation programs provide a strong foundation for biodiversity conservation in the United States, building on state wildlife action plans. However, states may miss the species that are at the most risk at rangewide scales, and threats such as novel diseases and climate change increasingly act at regional and national levels. Regional collaborations among states and their partners have had impressive successes, and several federal programs now incorporate state priorities. However, regional collaborations are uneven across the country, and no national counterpart exists to support efforts at that scale. A national conservation-support program could fill this gap and could work across the conservation community to identify large-scale conservation needs and support efforts to meet them. By providing important information-sharing and capacity-building services, such a program would advance collaborative conservation among the states and their partners, thus increasing both the effectiveness and the efficiency of conservation in the United States.

    Hearing aids often develop malfunctions that are not detected by the wearer. This is particularly true when the wearers are school-age children. Studies of selected groups showed that from 30 to more than 50 percent of school children were not getting adequate benefit from their hearing aids because of unrecognized malfunctions, usually low or dead batteries. This can be serious because hearing impairment retards a child's educational progress. NASA technology incorporated in the Hearing Aid Malfunction Detection Unit (HAMDU), the device pictured, is expected to provide an effective countermeasure to the childrens' hearing aid problem. A patent license has been awarded to a minority-owned firm, Hopkins International Company, a subsidiary of H. H. Aerospace Design Co., Inc., Elmford, New York. The company plans early commercial availability of its version of the device.

    2009-01-01

    Background The numerous studies examining where efforts to conserve biodiversity should be targeted are not matched by comparable research efforts addressing how conservation investments should be structured and what balance of conservation approaches works best in what contexts. An obvious starting point is to examine the past allocation of effort among conservation approaches and how this has evolved. Methodology/Principal Findings We examine the past allocation of conservation investment between conservation easements and fee simple acquisitions using the largest land trust in operation, The Nature Conservancy (TNC), as a case study. We analyse the balance of investments across the whole of the US and in individual states when measured in terms of the area protected and upfront cost of protecting land. Conclusions/Significance Across the US as a whole, the proportion of conservation investment allocated to easements is growing exponentially. Already 70% of the area of land protected in a given year, and half of all the financial investment in land conservation, is allocated to easements. The growth rate of conservation easements varies by a factor of two across states when measured in terms of the area protected and by a factor of three in terms of financial expenditure. Yet, we were unable to find consistent predictors that explained this variation. Our results underscore the urgency of implementing best practice guidelines for designing easements and of initiating a wider discussion of what balance of conservation approaches is desirable.

    Plant conservation genetics provides tools to guide conservation and restoration efforts, measure and monitor success, and ultimately minimize extinction risk by conserving species as dynamic entities capable of evolving in the face of changing conditions. We consider the application of these tools to rare and common species alike, as ongoing threats that increasingly limit their resilience, evolutionary potential and survival. Whereas neutral marker studies have contributed much to conservation genetics, we argue for a renewed focus on quantitative genetic studies to determine how, or if, species will adapt to changing conditions. Because restoration plays an increasingly vital role in conservation, we discuss additional genetic considerations and research questions that must be actively studied now to effectively inform future actions.

    In the 20 years since Conservation Biology was launched with the aim of disseminating scientific knowledge to help conserve biodiversity and the natural world, our discipline has hugely influenced the practice of conservation. But we have had less impact outside the profession itself and we have not transformed that practice into an enterprise large enough to achieve our conservation goals. As we look to the next 20 years, we need to become more relevant and important to the societies in which we live. To do so, the discipline of conservation biology must generate answers even when full scientific knowledge is lacking, structure scientific research around polices and debates that influence what we value as conservationists, go beyond the certitude of the biological sciences into the more contextual debates of the social sciences, engage scientifically with human-dominated landscapes, and address the question of how conservation can contribute to the improvement of human livelihoods and the quality of human life.

    Works on epidemiological, and social and behavioral science aspects of AIDS prevention and support in Africa are reviewed from the 7th Conference on AIDS. Participants were especially concerned with why AIDS spreads at disparate rates in different countries and regions of the world. Research on the casual factors of the spread of HIV generally focused upon patterns of sex behavior, the presence of other STDs, and the effect of circumcision. The roles of certain vaginal tightening agents used by Zairian prostitutes, vaginal bruising and bleeding, sex during menses, and oral contraception were also considered. Further, participants explored the possibility of a more coordinated, integrated approach to research and intervention development between the medical and social disciplines, and expressed the overall need for concurrent mass education interventions. In the face of ever increasing rates of HIV infection, including vertical transmission, making condoms ubiquitous, affordable, and highly publicized should garner higher general acceptance and use rates in these populations. Papers and models on the micro- and macro-socioeconomic impact of AIDS were finally discussed, followed by recommendations for a complete reassessment and reworking of policy for AIDS prevention. AIDS activities should, in fact, be integrated into the daily fabric of society, with prevention measures considered an ultimate necessity for social survival.

    Approximately 1% of all AIDS cases are haemophiliacs. LAV/HTLV-III is transmitted by blood and in factor VIII concentrates. Since 1981, increasing numbers of haemophiliacs have been infected, as indicated by detection of antibodies to LAV/HTLV-III. Up to 90% of haemophiliacs in some populations are now seropositive, but to date less than 1% have progressed to clinical AIDS. Immunological abnormalities, in particular reduced T-lymphocyte helper/suppressor ratios, are common in haemophiliacs treated with factor VIII. Such abnormalities do not necessarily indicate past infection by the AIDS virus, but they may predispose to infection following exposure to the virus. Blood Transfusion agencies are introducing screening tests for antibodies to LAV/HTLV-III to help prevent the spread of AIDS by blood products. Heat treated factor VIII concentrate is now available and appears not to transmit AIDS. Factor IX concentrate may also transmit LAV/HTLV-III, but less frequently. A few cases of AIDS have occurred in Haemophilia B (Christmas Disease) patients.

    2016-05-01

    Many remote sensing modalities have been developed for buried target detection (BTD), each one offering relative advantages over the others. There has been interest in combining several modalities into a single BTD system that benefits from the advantages of each constituent sensor. Recently an approach was developed, called multi-state management (MSM), that aims to achieve this goal by separating BTD system operation into discrete states, each with different sensor activity and system velocity. Additionally, a modeling approach, called Q-MSM, was developed to quickly analyze multi-modality BTD systems operating with MSM. This work extends previous work by demonstrating how Q-MSM modeling can be used to design BTD systems operating with MSM, and to guide research to yield the most performance benefits. In this work an MSM system is considered that combines a forward-looking infrared (FLIR) camera and a ground penetrating radar (GPR). Experiments are conducted using a dataset of real, field-collected, data which demonstrates how the Q-MSM model can be used to evaluate performance benefits of altering, or improving via research investment, various characteristics of the GPR and FLIR systems. Q-MSM permits fast analysis that can determine where system improvements will have the greatest impact, and can therefore help guide BTD research.

  4. Conservation Action Planning: Lessons learned from the St. Marys River watershed biodiversity conservation planning process

    2014-01-01

    Conservation Action Planning (CAP) is an adaptive management planning process refined by The Nature Conservancy (TNC) and embraced worldwide as the Open Standards for the Practice of Conservation. The CAP process facilitates open, multi-institutional collaboration on a common conservation agenda through organized actions and quantified results. While specifically designed for conservation efforts, the framework is adaptable and flexible to multiple scales and can be used for any collaborative planning effort. The CAP framework addresses inception; design and development of goals, measures, and strategies; and plan implementation and evaluation. The specific components of the CAP include defining the project scope and conservation targets; assessing the ecological viability; ascertaining threats and surrounding situation; identifying opportunities and designing strategies for action; and implementing actions and monitoring results. In 2007, TNC and a multidisciplinary graduate student team from the University of Michigan's School of Natural Resources and Environment initiated a CAP for the St. Marys River, the connecting channel between Lake Superior and Lake Huron, and its local watershed. The students not only gained experience in conservation planning, but also learned lessons that notably benefited the CAP process and were valuable for any successful collaborative effort—a dedicated core team improved product quality, accelerated the timeline, and provided necessary support for ongoing efforts; an academic approach in preparation for engagement in the planning process brought applicable scientific research to the forefront, enhanced workshop facilitation, and improved stakeholder participation; and early and continuous interactions with regional stakeholders improved cooperation and built a supportive network for collaboration.

    2012-01-01

    The principles of systematic conservation planning are now widely used by governments and non-government organizations alike to develop biodiversity conservation plans for countries, states, regions, and ecoregions. Many of the species and ecosystems these plans were designed to conserve are now being affected by climate change, and there is a critical need to incorporate new and complementary approaches into these plans that will aid species and ecosystems in adjusting to potential climate change impacts. We propose five approaches to climate change adaptation that can be integrated into existing or new biodiversity conservation plans: (1) conserving the geophysical stage, (2) protecting climatic refugia, (3) enhancing regional connectivity, (4) sustaining ecosystem process and function, and (5) capitalizing on opportunities emerging in response to climate change. We discuss both key assumptions behind each approach and the trade-offs involved in using the approach for conservation planning. We also summarize additional data beyond those typically used in systematic conservation plans required to implement these approaches. A major strength of these approaches is that they are largely robust to the uncertainty in how climate impacts may manifest in any given region.

  7. Biomedical and development paradigms in AIDS prevention.

    PubMed Central

    Wolffers, I.

    2000-01-01

    In the fight against the HIV/AIDS pandemic different approaches can be distinguished, reflecting professional backgrounds, world views and political interests. One important distinction is between the biomedical and the development paradigms. The biomedical paradigm is characterized by individualization and the concept of "risk". This again is related to the concept of the market where health is a product of services and progress a series of new discoveries that can be marketed. The development paradigm is characterized by participation of the different stakeholders and by community work. The concept "vulnerability" is important in the development paradigm and emphasis is placed on efforts to decrease this vulnerability in a variety of sustainable ways. Biomedical technology is definitely one of the tools in these efforts. In the beginning of the pandemic the biomedical approach was important for the discovery of the virus and understanding its epidemiology. Later, stakeholders became involved. In the light of absence of treatment or vaccines, the development paradigm became more important and the two approaches were more in balance. However, since the reports about effective treatment of AIDS and hope of development of vaccines, the biomedical paradigm has become a leading principle in many HIV/AIDS prevention programmes. There is a need for a better balance between the two paradigms. Especially in developing countries, where it is not realistic to think that sustainable biomedical interventions can be organized on a short-term basis, it would be counterproductive to base our efforts to deal with HIV/AIDS exclusively on the biomedical approach.

    In March 1994, the National AIDS Prevention and Control Programme in Pakistan launched its media campaign. Staffers have had to work within Islamic principles to inform the public about the risk of HIV infection and to encourage the public to adopt behavior to prevent its transmission. The media messages are not sexually explicit. They call for Pakistanis to call a hotline for or to ask medical professionals about more detailed information on AIDS. The hotline number is memorable (123). The 2 hotlines in Islamabad receive 250-300 calls/day. These hotlines deliver a recorded message with information on the significance of condoms in AIDS prevention and allows callers an opportunity to leave a telephone number or address if they want information. Staff advise callers who are concerned that they may be infected with HIV to obtain a test at 1 of 30 sites and to attend the National Institute for Health in Islamabad for more testing and counseling if the first test is positive. The hotline system will soon expand to all other major Pakistani cities. The program receives 300-400 letters/week asking for specific information. The program had workshops for journalists as its first wave of increasing AIDS awareness. The journalists followed with thoughtful articles on AIDS. Program staff spent much energy to obtain support from Islamic leaders. More media professionals have joined efforts to disseminate information through various media forums to encourage people to seek treatment for sexually transmitted diseases. The program's goal is a 55% increase in the number of people who can name at least 2 correct ways to prevent HIV transmission and an increase in condom use from 1% to 70%. The program eventually would like to increase outreach efforts by working with nongovernmental organizations and by developing videos and short stories.

In the past the Siona-Secoya worried little about conservation because they believed that good shamans attracted abundant game. When hunting was poor, shamans performedyagé ceremonies and appealed to supernatural gamekeepers for the release of more animals from the underworld. The sustainability of Siona-Secoya hunting was aided by factors such as low human population density, dispersed settlements within large hunting territories, settlement movement, and limited hunting technology. Today, increasing involvement in the national economy is leading the Siona-Secoya to invest more time in agriculture and wage labor, and less in traditional foraging activities. Colonization, deforestation, and industrial pollution now pose the greatest threats to wildlife in eastern Ecuador. Because of these changes, the Siona-Secoya are becoming interested in environmental protection and conservation. Several of their efforts to protect forest resources and mitigate pollution are discussed and evaluated.

  10. Dopamine and Effort-Based Decision Making

    Motivational theories of choice focus on the influence of goal values and strength of reinforcement to explain behavior. By contrast relatively little is known concerning how the cost of an action, such as effort expended, contributes to a decision to act. Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. Here we review behavioral and neurobiological data regarding the representation of effort as action cost, and how this impacts on decision making. Although organisms expend effort to obtain a desired reward there is a striking sensitivity to the amount of effort required, such that the net preference for an action decreases as effort cost increases. We discuss the contribution of the neurotransmitter dopamine (DA) toward overcoming response costs and in enhancing an animal's motivation toward effortful actions. We also consider the contribution of brain structures, including the basal ganglia and anterior cingulate cortex, in the internal generation of action involving a translation of reward expectation into effortful action.

    We explored age differences in the amount of personal effort that people put forth to maintain relationships across adulthood in diverse family-life contexts. More specifically, we examined how personal effort in social relationships is age-differently related to emotional closeness and perceptions of reciprocity. A total of 658 early-midlife (37 years) and old-age adults (73 years) from three life contexts (biological parents, parents from blended families with at least one stepchild, childless individuals) completed a questionnaire assessing ego-centered social networks, relationship quality, perceived conflict, and personal characteristics. As expected, perceived relationship effort was more pronounced and more strongly associated with emotional closeness in old age than in early midlife. In both age groups, perceived effort was comparably associated with reciprocity and conflict. Such associations were similar across the different life contexts. The findings suggest that perceived personal effort in social relationships contributes to the proactive shaping of social worlds across adulthood. PMID:23586359

    Objectives The dual-task paradigm has been widely used to measure listening effort. The primary objectives of the study were to (1) investigate the effect of hearing aid amplification and a hearing aid directional technology on listening effort measured by a complicated, more real world dual-task paradigm, and (2) compare the results obtained with this paradigm to a simpler laboratory-style dual-task paradigm. Design The listening effort of adults with hearing impairment was measured using two dual-task paradigms, wherein participants performed a speech recognition task simultaneously with either a driving task in a simulator or a visual reaction-time task in a sound-treated booth. The speech materials and road noises for the speech recognition task were recorded in a van traveling on the highway in three hearing aid conditions: unaided, aided with omni directional processing (OMNI), and aided with directional processing (DIR). The change in the driving task or the visual reaction-time task performance across the conditions quantified the change in listening effort. Results Compared to the driving-only condition, driving performance declined significantly with the addition of the speech recognition task. Although the speech recognition score was higher in the OMNI and DIR conditions than in the unaided condition, driving performance was similar across these three conditions, suggesting that listening effort was not affected by amplification and directional processing. Results from the simple dual-task paradigm showed a similar trend: hearing aid technologies improved speech recognition performance, but did not affect performance in the visual reaction-time task (i.e., reduce listening effort). The correlation between listening effort measured using the driving paradigm and the visual reaction-time task paradigm was significant. The finding showing that our older (56 to 85 years old) participants’ better speech recognition performance did not result in reduced

    The status of freshwater fishes continues to decline despite substantial conservation efforts to reverse this trend and recover threatened and endangered aquatic species. Lack of success is partially due to working at smaller spatial scales and focusing on habitats and species that are already degraded. Protecting entire watersheds and aquatic communities, which we term "native fish conservation areas" (NFCAs), would complement existing conservation efforts by protecting intact aquatic communities while allowing compatible uses. Four critical elements need to be met within a NFCA: (1) maintain processes that create habitat complexity, diversity, and connectivity; (2) nurture all of the life history stages of the fishes being protected; (3) include a long-term enough watershed to provide long-term persistence of native fish populations; and (4) provide management that is sustainable over time. We describe how a network of protected watersheds could be created that would anchor aquatic conservation needs in river basins across the country.

    Business has transformed the planet. But this gives it new responsibilities. People now expect business leaders to lead--and not just respond when things go wrong. HIV/AIDS is a global problem, with over 16.3 million people now thought to have died of the disease (Global Summary of HIV/AIDS Epidemic, UNAIDS, December 1999). Without action now, the pandemic will worsen, health services will come under relentless pressure and the number of people dying will increase exponentially. So why should business sit up and take notice? First: money. AIDS is slowly strangling many businesses and economies--and in a global market, everyone eventually suffers. Without profit, there is no business--so the business community needs to act to protect its bottom line. Second: people. Over 80% of those dying are in their 20s, 30s, and 40s. Businesses are losing workers and customers, and human networks that have taken decades to build. Third: imagination. Business is inventive, creative and fast-moving. It has the opportunity to use these strengths for the benefit of the wider community. It's time to pit business ideas (and some money, too) against the threat of AIDS. The course of the AIDS epidemic is not inevitable. The world's businesses have the skills and intensity to make a measurable difference, especially if they find public sector and NGO partners with whom they share a vision. A focused, coordinated, results-driven effort will hit AIDS hard. The HIV virus moves fast (and is mutating all the time). Business has the opportunity to make a difference. It must grasp this opportunity. And grasp if fast. PMID:11051635

    ELLPACK is a problem statement language and system for elliptic partial differential equations which is implemented by a FORTRAN preprocessor. ELLPACK's principal purpose is as a tool for the performance evaluation of software. However, it is used here as an example with which to study the programming effort required for problem solving. It is obvious that problem statement languages can reduce programming effort tremendously; the goal is to quantify this somewhat. This is done by analyzing the lengths and effort (as measured by Halstead's software science technique) of various approaches to solving these problems.

    The Department of Defense (DoD) is dismantling its U.S. HIV clinical research program in favor of preventive vaccine work in Thailand. The rationale for this decision is that HIV-infected personnel are considered casualties and, therefore, of limited use to the force. Closure of the clinical portion of the DoD program will have several serious effects on the nation's overall AIDS research effort. For example, the military AIDS research program has developed the only surveillance system for transmission of drug-resistant strains of HIV and, due to a study population with known dates of seroconversion, continues to do the bulk of work in that area. The closure of DoD domestic clinical HIV research will also leave at least 11,000 HIV-infected service people with limited, if not nonexistent, access to clinical trials. The Administration's budget also seeks a 23 percent funding reduction in the DoD research program, a proposal that Congress may not altogether reject. It appears the military's intent is to funnel the entire programmed budget for FY '96 into preventive vaccine development. Project Inform rejects any reduction or closure actions by the military of their AIDS research program. To join the effort, call the PI hotline at 1-800-822-7422. PMID:11362423

    We used linear and multivariate models to examine the associations between geography, biodiversity, per capita economic output, national spending on conservation, governance, and cultural traits in 55 countries. Cultural traits and social metrics of modernization correlated positively with national spending on conservation. The global distribution of this spending culture was poorly aligned with the distribution of biodiversity. Specifically, biodiversity was greater in the tropics where cultures tended to spend relatively less on conservation and tended to have higher collectivism, formalized and hierarchical leadership, and weaker governance. Consequently, nations lacking social traits frequently associated with modernization, environmentalism, and conservation spending have the largest component of Earth's biodiversity. This has significant implications for setting policies and priorities for resource management given that biological diversity is rapidly disappearing and cultural traits change slowly. Therefore, we suggest natural resource management adapt to and use characteristics of existing social organization rather than wait for or promote social values associated with conservation spending. Supporting biocultural traditions, engaging leaders to increase conservation commitments, cross-national efforts that complement attributes of cultures, and avoiding interference with nature may work best to conserve nature in collective and hierarchical societies. Spending in modernized nations may be a symbolic response to a symptom of economic development and environmental degradation, and here conservation actions need to ensure that biodiversity is not being lost.

    Gay male teenagers face considerable adversity during their "coming out" process due to the AIDS epidemic. They must decide whether to be tested for HIV-1 infection, whether to postpone sexual activity, how to select a partner, and which kinds of sexual practices to engage in. Gay youth often make such decisions based upon misinformation and faulty premises. This paper reviews what is known about gay youth and AIDS, and assesses their possible risk for HIV-1 infection. It is recommended that school and community-based health education programs be developed to teach gay and bisexual youth about safe sex. Moreover, research is needed into sociocultural variations among gay youth in order to develop appropriate and effective intervention strategies for AIDS risk reduction in this diverse population.

    The Indian Health Organization projected the number of deaths per day due to AIDS by the year 2000 at 10,000. An interdisciplinary international conference was held in New Delhi to draft an international law governing the issues related to AIDS. Human freedom and public health policies are the most affected by this disease. In the absence of an international AIDS law, judicial verdicts set precedents and could have serious ramifications. A participant from the John Marshall Law School, Chicago, suggested that instead of making new laws, the existing ones from the colonial past should be repealed. This includes Section 377 of the Indian Penal Code, which provides criminal sanctions against those who indulge in unnatural relations with man, woman, or animal. Penalizing homosexuality will only perpetuate clandestine relations and spread the virus into their families. Another participant seconded this motion stating that even a sex worker must be protected from abuse and indignity. The National AIDS Control Organization responded to the criticism that the government had not utilized all the World Bank funds allocated for anti-AIDS projects. The trends of the epidemic were the most important indicators not just the numbers. In Manipur and Mizoram, infection was almost entirely due to injecting drug use. The Saheli project undertaken in the red-light areas of Bombay encompassed brothel owners and prostitutes, which could be replicated in other areas. Because existing government policies were focusing on prevention, there was no protection of an HIV-infected individual's privacy, one participant from Madras stated. The confidentiality issue was also echoed by a US participant. The New Delhi Declaration and Action Plan on HIV/AIDS was also discussed. It forbids discrimination in employment, education, housing, health care, social security, travel, and marital and reproductive rights. Providing sterile needles and ensuring the safety of the blood supply were other concerns

  1. AIDS--legal issues.

    PubMed

    Kirby, M

    1988-01-01

    Legal issues worldwide prompted by the AIDS epidemic are discussed, in a general way, since legal systems vary widely in different countries and localities. WHO publishes a tabulation of legal instruments dealing with AIDS and HIV infection. Criminal laws intended to protect people from harm from HIV infection have been enacted, such as a penalty for unprotected sexual intercourse by infected persons, in some Australian states. Knowing spread of HIV already amounts to a crime in many systems. The U.S. Supreme Court has already ruled that states do not violate the constitution for punishing homosexuals for consensual sodomy, nor the Army for discharging homosexuals. Quarantine law is a civil matter, but may provide penalties stricter than criminal penalties, without as much protection. No quarantines against AIDS have been enacted, although some countries require screening of immigrants. Legal issues regarding screening, liability of suppliers of blood products, and tracing of sexual partners are much discussed. Stigmatization of minority and alienated groups such as homosexuals, prostitutes, migrants, drug users and prisoners is a tricky legal problem. The apparent failure of the criminalization of drug users and how to contain the spread of AIDS into the drug free population may prompt drastic new solutions. Other legal issues drawing attention include regulation of health insurance, changes in family law, pre-marriage HIV tests, screening for HIV ostensibly to detect HIV-associated dementia, liability protection for developers and testers of vaccines, and euthanasia and the treatment of the deceased. The legal system tends to lag behind medicine. In the case of AIDS, it cannot afford to delay, therefore effective legal strategies will include effective media presentation of AIDS information to the general public; ready and cheap supply of condoms; and a new approach to illegal drugs.

    Species conservation via the Endangered Species Act is highly politicized, yet few data have been gathered to illustrate the relationship of political party affiliation to species conservation perspectives. We conducted a nationwide public opinion survey and found that Democrats value species conservation more highly than do Republicans, and that Democrats are also more strongly supportive of the Endangered Species Act. Republicans place higher value on property rights than do Democrats, but members of both parties value economic growth as highly as wildlife conservation. The results imply that the Democratic propensity to value species conservation reflects a biocentric perspective that does not bode well for practical conservation efforts. Species conservation will depend upon the success of academicians and progressive political leaders in educating students and members of all parties about the fundamental conflict between economic growth and wildlife conservation.

    HIV/AIDS is a major public health problem worldwide, especially in developing countries. The development of a safe and effective HIV vaccine is central to stopping the epidemic and would be a great public health tool. The AIDS Vaccine for Asia Network (AVAN) is a group of concerned investigators committed to assisting regional and global HIV vaccine efforts. AVAN's focus on improving the coordination and harmonization of research, ethical reviews, clinical trial capacity, regulatory frameworks, vaccine manufacturing, community participation, and government advocacy could help accelerate HIV vaccine efforts in the region. At a meeting in November 2010, researchers from various countries in Asia presented their progress in HIV vaccine research and development. Six working groups discussed the current status, gaps and methods to strengthen capacity and infrastructure in various areas related to AIDS vaccine research and development. These discussions led to the development of prioritized action plans for the next 5 years. This report describes the gaps and challenges HIV vaccine research faces in the region and recommends improvement and standardization of facilities, and coordination and harmonization of all activities related to AIDS vaccine research and development, including possible technology transfer when a vaccine becomes available.

    This paper reports that for most utilities, computer aided engineering (CAE) systems are currently used for operating plant support rather than new plant design particularly for nuclear plant maintenance. For nuclear power generating utilities, switching to a modern, integrated CAE information system can offer significant benefits. During the last decade, however, most engineering automation in the power generation industry focused on computer-aided drafting and stand-alone engineering applications. An integrated CAE system can be a useful too, assisting engineers with many engineering and operational activities. It also can be used to manage the massive amount of information created throughout the life of a plant.

    Background Despite continued global efforts, HIV/AIDS outcomes in developing countries have not made much progress. Poor governance in recipient countries is often seen as one of the reasons for ineffectiveness of aid efforts to achieve stated objectives and desired outcomes. Objective This study examines the impact of two important dimensions of governance – control of corruption and democratic accountability – on the effectiveness of HIV/AIDS official development assistance. Design An empirical analysis using dynamic panel Generalized Method of Moments estimation was conducted on 2001–2010 datasets. Results Control of corruption and democratic accountability revealed an independent effect and interaction with the amount of HIV/AIDS aid on incidence of HIV/AIDS, respectively, while none of the two governance variables had a significant effect on HIV/AIDS prevalence. Specifically, in countries with accountability level below −2.269, aid has a detrimental effect on incidence of HIV/AIDS. Conclusion The study findings suggest that aid programs need to be preceded or at least accompanied by serious efforts to improve governance in recipient countries and that democratic accountability ought to receive more critical attention.

    There is increasing concern about the conservation status of sharks. However, the presence of numerous different (and potentially mutually exclusive) policies complicates management implementation and public understanding of the process. We distributed an online survey to members of the largest professional shark and ray research societies to assess member knowledge of and attitudes toward different conservation policies. Questions covered society member opinions on conservation and management policies, personal histories of involvement in advocacy and management, and perceptions of the approach of conservation nongovernmental organizations (NGOs) to shark conservation. One hundred and two surveys were completed (overall response rate 21%). Respondents considered themselves knowledgeable about and actively involved in conservation and management policy; a majority believed scientists have a responsibility to advocate for conservation (75%), and majorities have sent formal public comments to policymakers (54%) and included policy suggestions in their papers (53%). They believe sustainable shark fisheries are possible, are currently happening today (in a few places), and should be the goal instead of banning fisheries. Respondents were generally less supportive of newer limit-based (i.e., policies that ban exploitation entirely without a species-specific focus) conservation policy tools, such as shark sanctuaries and bans on the sale of shark fins, than of target-based fisheries management tools (i.e., policies that allow for sustainable harvest of species whose populations can withstand it), such as fishing quotas. Respondents were generally supportive of environmental NGO efforts to conserve sharks but raised concerns about some NGOs that they perceived as using incorrect information and focusing on the wrong problems. Our results show there is an ongoing debate in shark conservation and management circles relative to environmental policy on target-based natural

  11. The couple approach to HIV / AIDS prevention.

    Alvarez, R O

    1995-01-01

    In 1995, the Philippine Overseas Employment Administration reported that there were 360,000 documented contract workers deployed to various international destinations, 33.1% of whom were sea-based contract workers. It is accepted in Philippine society that seamen stationed abroad for several months remain sexually active. They often have unprotected sexual intercourse with several male and female sex partners, exposing themselves and their partners to the risk of acquiring sexually transmitted infections. The Department of Health has therefore given some priority to involve overseas workers in AIDS education efforts. Seamen, in particular, have been found to engage in high-risk behaviors based upon the recognized routes of HIV transmission. The ISSA developed and implemented a project to address the HIV/AIDS education needs of this group of men and their partners. ISSA's HIV/AIDS Education and Prevention project used the couple approach in its activities, noting that couples and partners must work together to practice safer sex measures. The project involved 60 seamen and 60 women who were either wives or girlfriends of the seamen; more than half of the participants were husband-wife couples. The project functioned upon the premise that both partners have to be well-informed about HIV/AIDS in order to practice effective prevention measures.

  13. Contending with uncertainty in conservation management decisions

    PubMed Central

    McCarthy, Michael A

    2014-01-01

    Efficient conservation management is particularly important because current spending is estimated to be insufficient to conserve the world's biodiversity. However, efficient management is confounded by uncertainty that pervades conservation management decisions. Uncertainties exist in objectives, dynamics of systems, the set of management options available, the influence of these management options, and the constraints on these options. Probabilistic and nonprobabilistic quantitative methods can help contend with these uncertainties. The vast majority of these account for known epistemic uncertainties, with methods optimizing the expected performance or finding solutions that achieve minimum performance requirements. Ignorance and indeterminacy continue to confound environmental management problems. While quantitative methods to account for uncertainty must aid decisions if the underlying models are sufficient approximations of reality, whether such models are sufficiently accurate has not yet been examined.

  16. Facets of job effort in bus driver health: deconstructing "effort" in the effort-reward imbalance model.

    PubMed

    Tse, John L M; Flin, Rhona; Mearns, Kathryn

    2007-01-01

    This research aimed to test the relative value of developing and using job-specific facets of effort and testing them using J. Siegrist's (1996) effort-reward imbalance (ERI) theory to extend understanding of how one might determine job strain in urban bus driving. In addition, the interactive effects of the ERI model are further investigated to address the lack of research into the relationships of the model's constructs. Using focus groups and published papers, a measure of bus driver effort was created, which was subsequently completed by 186 male U.K. bus drivers as part of a questionnaire study. The results were factor analyzed to create 4 facets of effort, which demonstrated additional variance in predicting strain, above and beyond J. Siegrist's original effort construct. One facet, workload and fatigue, was observed to be a particularly important contributor to strain. The analyses further indicated that the ERI model's assumptions that ERI creates job strain could not be completely upheld, although poorer levels of reward and higher levels of overcommitment were strong main predictors of job strain. Research and applied implications are considered.

  19. Women and AIDS: the ethics of exaggerated harm.

    PubMed

    Mertz, David; Sushinsky, Mary Ann; Schüklenk, Udo

    1996-04-01

    This article examines the way in which some biomedical ethicists have constructed sexually transmitted AIDS as a significant threat to women's health. We demonstrate that the familiar claim that 'women are the fastest growing group' -- whether of HIV-infected or of AIDS patients -- is misleading because it obscures the distinction between proportional rate of growth and absolute increase. Feminist ethicists have suggested that misogyny of a male dominated health care system has led to underreporting of women AIDS cases in order to support these feminists' claim of AIDS being a real threat to women's health. Given the apparent rarity of tertiary transmissions of AIDS, the assertion that most or even many women are at significant risk for AIDS seems wrong. Particularly disturbing in this campaign is the fact that the theme of 'risky sex' has been extended all the way to lesbians, even though their risk to acquire AIDS sexually is non-existent to miniscule. We argue that actual harm is done to women by this exaggeration of their risk of contracting AIDS sexually. The scare has led to misappropriations of scarce health care funds. AIDS disproportionately affects women who inject drugs, and who suffer other diseases, poverty and malnutrition. It would have been better to concentrate health care efforts in this area instead of 'educating' women not at risk for AIDS how to prevent the acquisition of this disease. Unjustifiable AIDS anxiety has been created in women and has resulted in millions of unnecessary HIV-tests, and many broken relationships. This anxiety has inevitably reduced the pleasure of having sex for many women. We reject the kind of 'victim ideology' that lies at the heart of this strategy which has, unfortunately, been supported by a number of influential feminist ethicists.

    Sponges are important for maintaining ecosystem function and integrity of marine and freshwater benthic communities worldwide. Despite this, there has been no assessment of their current global conservation status. We assessed their status, accounting for the distribution of research effort; patterns of temporal variation in sponge populations and assemblages; the number of sponges on threatened species lists; and the impact of environmental pressures. Sponge research effort has been variable; marine sponges in the northeastern Atlantic and Mediterranean and freshwater sponges in Europe and North America have received the most attention. Although sponge abundance has increased in some locations since 1990, these were typically on coral reefs, in response to declines in other benthic organisms, and restricted to a few species. Few data were available on temporal trends in freshwater sponge abundance. Despite over 8500 described sponge species, only 20 are on threatened species lists, and all are marine species from the northeastern Atlantic and Mediterranean. Of the 202 studies identified, the effects of temperature, suspended sediment, substratum loss, and microbial pathogens have been studied the most intensively for marine sponges, although responses appear to be variable. There were 20 studies examining environmental impacts on freshwater sponges, and most of these were on temperature and heavy metal contamination. We found that most sponges do not appear to be threatened globally. However, little information is available for most species and more data are needed on the impacts of anthropogenic-related pressures. This is a critical information gap in understanding sponge conservation status.

    Colombia, like many developing countries, has not committed resources to fight the AIDS problem. They have used the media for condom promotion and other sexually transmitted diseases. There have been 151 deaths caused by AIDS by the end of 1988; 344 cases are known, and 130 additional have tested positive to the virus. Health officials were reluctant to recognize the problem, thinking it was outside their country and that they would not be affected by it. Since then, they have tried to target high risk groups and educate them and assist with testing and counseling. There is a move to make the new drug zidovudine available, but few could afford its high price. The authorities have put transvestite prostitutes in jail and kept them for AIDS testing, but few woman prostitutes have been tested. Up until 1986, only 30% of the Red Cross blood bank supplies were being tested; now 80% are, although it comprises only about 40% of the total supply. Drugs are used heavily, but mostly smoked, in Colombia, yet there is some concern about increased use of needles. The majority of cases in Columbia have been homosexual and bisexual men, but prostitution among men and women is prevalent in large cities such as Bogota. Health officials state that education is the best deterrent, but must be perpetuated so people will be constantly reminded. PMID:12282910

This report updates and summarizes information on North American rallids since the ARP report and identifies the major conservation problems of this group with the intent of focusing future efforts on these priority issues. Consideration of island forms occurring within U.S. possessions is beyond the scope of this report, mainly because of the special conservation problems associated with their insular distribution. The major topics include habitat requirements, effects of habitat and hunting management techniques currently practiced on wetland areas, and conservation of endangered and threatened populations. Research needs are identified. Habitats of the American Coot are similar to those of several waterfowl species, and the biology of coots is considered only as it is typical of rails in general.

    PubMed

    Rogers-Bennett, Laura; Leaf, Robert T

    2006-02-01

    Prospective elasticity analyses have been used to aid in the management of fished species and the conservation of endangered species. Elasticities were examined for deterministic size-based matrix models of red abalone, Haliotis rufescens, and white abalone, H. sorenseni, to evaluate which size classes influenced population growth (lambda) the most. In the red abalone matrix, growth transitions were determined from a tag recapture study and grouped into nine size classes. In the white abalone matrix, abalone growth was determined from a laboratory study and grouped into five size classes. Survivorship was estimated from tag recapture data for red abalone using a Jolly-Seber model with size as a covariate and used for both red and white abalone. Reproduction estimates for both models used averages of the number of mature eggs produced by female red and white abalone in each size class from four-year reproduction studies. Population growth rate (lambda) was set to 1.0, and the first-year survival (larval survival through to the first size class) was estimated by iteration. Survival elasticities were higher than fecundity elasticities in both the red and white matrix models. The sizes classes with the greatest survival elasticities, and therefore the most influence on population growth in the model, were the sublegal red abalone (150-178 mm) and the largest white abalone size class (140-175 mm). For red abalone, the existing minimum legal size (178 mm) protects the size class the model suggests is critical to population growth. Implementation of education programs for novice divers coupled with renewed enforcement may serve to minimize incidental mortality of the critical size class. For white abalone, conservation efforts directed at restoring adults may have more of an impact on population growth than efforts focusing on juveniles. Our work is an example of how prospective elasticity analyses of size-structured matrix models can be used to quantitatively evaluate

    1985-03-29

    Tests to detect serum antibody to human T-lymphotropic virus type III (HTLV-III), based on an enzyme-linked immunosorbent assay (ELISA) that uses whole disrupted HTLV-III virus antigens, are now commercially available in the US. Recent surveys of groups at high risk for acquired immunodeficiency syndrome (AIDS) have found that 22-65% of homosexual men, 87% of active intravenous drug users, 56-72% of hemophiliacs, and 35% of women who were sexual partners of men with AIDS have had postitive ELISA tests compared with fewer than 1% of those with no known risk factors. A positive ELISA test could be due to subclinical infection, immunity, or cross-reactivity with other viral antigens. Laboratory error can also produce false positive results. Thus, it is recommended that the ELISA test be repeated at least once on all seropositive specimens before the result is reported to the patient. The western blot test appears to be more specific and less sensitive than the ELISA. Studies of asymptomatic seropositive homosexual men followed for 2-5 years have found that over 50% remain asymptomatic, 5-19% develop full blown AIDS, and 25% develop signs suggestive of the AIDS-related complex. Asymptomatic patients with positive ELISA tests should be made aware of early signs and symptoms of AIDS. Other data suggest that seropositive patients have the HTLV-III virus in their blood, semen, and/or saliva and can transmit the infection. Precautions to prevent transmission, such as the use of condoms, should be taken by such patients. Physicians should be sensitive to the fear and anxiety that a positive ELISA test will create.

  8. AIDS: there's hope.

    PubMed

    1993-06-01

    In 1993, 10 years after realizing that AIDS posed a threat to the future of mankind, social mobilization will improve the odds against AIDS. The objective is to create awareness about the virus, and to affect positive behavioral change through advocacy, communication, and grass-roots actions. The first goal is to change the societal attitude about the status of youth and women in order to understand that gender inequality fuels the pandemic. They are the most vulnerable groups, therefore their economic and social power must be improved. The Convention on the Rights of the Child and the Convention on the Elimination of All Forms of Discrimination against Women constitute a platform for broader action by governmental, nongovernmental, and religious institutions. In addition, these organizations need strong allies in society: 1) the media, which can communicate the importance of youth, women, and attitudes in the epidemic; 2) religious leaders, who can be powerful sources of advocacy for change in attitudes as well as support and care for AIDS-affected individuals and families; 3) policy makers, who can be crucial in changing existing policies and altering the allocation of government resources to youth and women; 4) human rights organizations, which play an important role in promoting the concept of health as a human right and for enhancing the understanding of AIDS in the context of discrimination and poverty; 5) the private sector, including commerce and industry, which can promote changes in attitude within the work force and AIDS prevention initiatives; and 6) parent-teacher groups and models for youth, who can educate them about socially acceptable and unacceptable behavior and can empower them to make responsible behavior choices.

  9. Productive and ineffective efforts: how student effort in high school mathematics relates to college calculus success

    Relativizing the popular belief that student effort is the key to success, this article finds that effort in the most advanced mathematics course in US high schools is not consistently associated with college calculus performance. We distinguish two types of student effort: productive and ineffective efforts. Whereas the former carries the commonly expected benefits, the latter is associated with negative consequences. Time spent reading the course text in US high schools was negatively related to college calculus performance. Daily study time, however, was found to be either a productive or an ineffective effort, depending on the level of high school mathematics course and the student's performance in it.

  10. Expanding the partnership. The private sector's role in HIV / AIDS prevention.

    The public sector supports most HIV/AIDS prevention and care activities in developing countries, with significant funding provided by the US Agency for International Development, the Overseas Development Authority, the European Community, and international banking institutions such as the World Bank. Local nongovernmental organizations (NGOs) and international private voluntary organizations (PVOs) implement many of the grassroots prevention and care efforts in developing countries, but often require support from donor agencies. While the private commercial sector has played a minor role in supporting HIV/AIDS prevention and care efforts, a number of local and multinational companies are beginning to recognize the importance of protecting their workers from HIV infection. These companies are motivated by a sense of moral obligation and/or view HIV/AIDS prevention as a cost-effective investment. Mainly affecting the most economically productive age groups, the HIV/AIDS epidemic will have a significant impact upon private industry. Workplace-based prevention programs and policies, private sector resources for HIV/AIDS prevention and care, how HIV/AIDS programs can benefit from the private sector's experience in commercial service delivery, research and development, and corporate direct cash and in-kind contributions to government and NGO HIV/AIDS prevention activities are discussed. The AIDS Control and Prevention (AIDSCAP) Project's Businesses Managing AIDS Project helps owners and managers understand the potential impact of HIV/AIDS upon their businesses and the benefits of HIV/AIDS prevention.

    Traditional explicit numerical discretizations of conservative systems generically predict artificial secular drifts of any nonlinear invariants. In this work the authors present a general approach for developing explicit nontraditional algorithms that conserve such invariants exactly. They illustrate the method by applying it to the three-wave truncation of the Euler equations, the Lotka-Volterra predator-prey model, and the Kepler problem. The ideas are discussed in the context of symplectic (phase-space-conserving) integration methods as well as nonsymplectic conservative methods. They comment on the application of the method to general conservative systems.

    The following aspects of energy conservation were reviewed in order to place the problems in proper perspective: history and goals, conservation accounting-criteria, and a method to overcome obstacles. The effect of changing prices and available supplies of energy sources and their causes on consumption levels during the last few decades were described. Some examples of attainable conservation goals were listed and justified. A number of specific criteria applicable to conservation accounting were given. Finally, a discussion was presented to relate together the following aspects of energy conservation: widespread impact, involvement of government, industry, politics, moral and ethical aspects, urgency and time element.

    Climate change is expected to impact ecosystems directly, such as through shifting climatic controls on species ranges, and indirectly, for example through changes in human land use that may result in habitat loss. Shifting patterns of agricultural production in response to climate change have received little attention as a potential impact pathway for ecosystems. Wine grape production provides a good test case for measuring indirect impacts mediated by changes in agriculture, because viticulture is sensitive to climate and is concentrated in Mediterranean climate regions that are global biodiversity hotspots. Here we demonstrate that, on a global scale, the impacts of climate change on viticultural suitability are substantial, leading to possible conservation conflicts in land use and freshwater ecosystems. Area suitable for viticulture decreases 25% to 73% in major wine producing regions by 2050 in the higher RCP 8.5 concentration pathway and 19% to 62% in the lower RCP 4.5. Climate change may cause establishment of vineyards at higher elevations that will increase impacts on upland ecosystems and may lead to conversion of natural vegetation as production shifts to higher latitudes in areas such as western North America. Attempts to maintain wine grape productivity and quality in the face of warming may be associated with increased water use for irrigation and to cool grapes through misting or sprinkling, creating potential for freshwater conservation impacts. Agricultural adaptation and conservation efforts are needed that anticipate these multiple possible indirect effects. PMID:23569231

    The relationship between voice handicap and professional vocal effort was investigated among teachers in a cross-sectional study of census nature on 4496 teachers within the public elementary education network in Salvador, Bahia, Brazil. Voice handicap (the outcome of interest) was evaluated using the Voice Handicap Index 10. The main exposure, the lifetime vocal effort index, was obtained as the product of the number of years working as a teacher multiplied by the mean weekly working hours. The prevalence of voice handicap was 28.8% among teachers with high professional vocal effort and 21.3% among those with acceptable vocal effort, thus yielding a crude prevalence ratio (PR) of 1.36 (95% confidence interval [CI]=1.14-1.61). In the final logistic model, the prevalence of voice handicap was statistically associated with the professional vocal effort index (PR=1.47; 95% CI=1.19-1.82), adjusted according to sex, microphone availability in the classroom, excessive noise, pressure from the school management, heartburn, and rhinitis.

  19. Measuring Evolutionary Isolation for Conservation.

    2014-01-01

    Conservation planning needs to account for limited resources when choosing those species on which to focus attention and resources. Currently, funding is biased to small sections of the tree of life, such as raptors and carnivores. One new approach for increasing the diversity of species under consideration considers how many close relatives a species has in its evolutionary tree. At least eleven different ways to measure this characteristic on phylogenies for the purposes of setting species-specific priorities for conservation have been proposed. We find that there is much redundancy within the current set, with three pairs of metrics being essentially identical. Non-redundant metrics represent different trade-offs between the unique evolutionary history represented by a species verses its average distance to all other species. Depending on which metric is used, species priority lists can differ as much as 85% for the top 100 species. We call for some consensus on the theory behind these metrics and suggest that all future developments are compared to the current published set, and offer scripts to aid such comparisons.

    Activation-induced deaminase (AID) functions by deaminating cytosines and causing U:G mismatches, a rate-limiting step of Ab gene diversification. However, precise mechanisms regulating AID deamination frequency remain incompletely understood. Moreover, it is not known whether different sequence contexts influence the preferential access of mismatch repair or uracil glycosylase (UNG) to AID-initiated U:G mismatches. In this study, we employed two knock-in models to directly compare the mutability of core Sμ and VDJ exon sequences and their ability to regulate AID deamination and subsequent repair process. We find that the switch (S) region is a much more efficient AID deamination target than the V region. Igh locus AID-initiated lesions are processed by error-free and error-prone repair. S region U:G mismatches are preferentially accessed by UNG, leading to more UNG-dependent deletions, enhanced by mismatch repair deficiency. V region mutation hotspots are largely determined by AID deamination. Recurrent and conserved S region motifs potentially function as spacers between AID deamination hotspots. We conclude that the pattern of mutation hotspots and DNA break generation is influenced by sequence-intrinsic properties, which regulate AID deamination and affect the preferential access of downstream repair. Our studies reveal an evolutionarily conserved role for substrate sequences in regulating Ab gene diversity and AID targeting specificity.

  1. Sources of avoidance motivation: Valence effects from physical effort and mental rotation.

    When reaching goals, organisms must simultaneously meet the overarching goal of conserving energy. According to the law of least effort, organisms will select the means associated with the least effort. The mechanisms underlying this bias remain unknown. One hypothesis is that organisms come to avoid situations associated with unnecessary effort by generating a negative valence toward the stimuli associated with such situations. Accordingly, merely using a dysfunctional, 'slow' computer mouse causes participants to dislike ambient neutral images (Study 1). In Study 2, nonsense shapes were liked less when associated with effortful processing (135° of mental rotation) versus easier processing (45° of rotation). Complementing 'fluency' effects found in perceptuo-semantic research, valence emerged from action-related processing in a principled fashion. The findings imply that negative valence associations may underlie avoidance motivations, and have practical implications for educational/workplace contexts in which effort and positive affect are conducive to success.

    The 105th Congress may prove to be more conservative than the outgoing 104th Congress, leaving AIDS advocates concerned about support for and interest in AIDS funding and policy measures. At least four senators with records of being sympathetic to AIDS funding, have been replaced by newcomers regarded as unsupportive. Senator Nancy Kassebaum, who helped push the Ryan White CARE Act reauthorization through Congress, was replaced by Rep. Pat Roberts, a Kansas Republican who voted with AIDS Action Council positions only 20 percent of the time. AIDS policy advocates announce one major gain in the election of Rep. Tim Johnson, a Democrat, who defeated Sen. Larry Pressler, a Republican from South Dakota. The senate committee structure will undergo major changes. Sen. James Jefford (R-VT), likely to head the Labor and Human Resources Committee, is highly regarded among AIDS policy advocates. The final tally in the race between Rep. Robert K. Dornan (R-CA), a vocal critic of Federal AIDS policies, and Democratic challenger, Loretta Sanchez, is being investigated.

    1988-03-01

    In order to be effective, the national effort to contain the spread of Acquired Immunodeficiency Syndrome (AIDS) must include a youth focus. Knowledge of adolescent sexual behavior, drug use, and sexually transmitted diseases suggests that many adolescents are in jeopardy of acquiring Human Immunodeficiency Virus (HIV) infections; and they are among those most likely to benefit from preventative efforts as they explore adult roles and lifestyles. Preventative education should particularly target gay and other homosexually active young men. Effective teaching uses a variety of approaches and media, both inside and outside the classroom. Learning about AIDS is most likely to effect behavioral change when accompanied by other programs to build social supports, self-esteem, and positive identity. The ethical and rational use of HIV antibody testing may be a helpful adjunct to education for certain adolescents. Ultimately, our society's ability to address complex, associated social issues will determine our ability to control AIDS.

  11. Human parental effort and environmental risk

    PubMed Central

    Quinlan, Robert J

    2006-01-01

    Parental investment decisions depend on multiple factors, including the extent that parental care benefits offspring. Humans should show reduced parental effort in environments where parenting cannot improve offspring survival. Data from the standard cross-cultural sample are used to test this prediction. The results show that maternal care was inversely associated with famine and warfare, and also showed a quadratic association with pathogen stress, increasing as pathogen stress increased to moderate levels, but decreasing at higher levels. Age at weaning showed a similar quadratic relation with pathogens. The curvilinear associations between parental effort and pathogen stress may reflect that the saturation point of parental care is a function of environmental hazards. Paternal involvement was also inversely related to pathogen stress. The association between pathogens and paternal involvement was partially mediated by polygyny. In sum, maternal and paternal care appears to have somewhat different relations with environmental hazards, presumably owing to sex-specific tradeoffs in reproductive effort. PMID:17134996
