Engaging Local Non-Governmental Organizations (NGOs) in the Response to HIV/AIDS.
During the past few years, a number of key donor programs have scaled up their global response to the crisis of HIV and AIDS. The Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM), the World Health Organization (WHO), the Joint United Nations Programme on HIV/AIDS (UNAIDS), the President’s Emergency Plan for AIDS Relief (PEPFAR), the United Nations’ Millennium Development Goals (MDGs), the World Bank’s Multi-country HIV/AIDS Program (MAP), and other bilateral donors and charitable foundations have raised significant resources to fight HIV/AIDS. Spending on HIV/AIDS in low- and middle-income countries increased from 6.1 billion in 2004. By 2007, global resources for HIV/AIDS are expected to expand to $10 billion. Local non-governmental organizations (NGOs), faith-based organizations (FBOs), and community-based organizations (CBOs) have been at the center of the response to the HIV/AIDS pandemic. In many countries, they have been responsible for the majority of the resources reaching individuals and have played a leading role in developing and implementing sustainable strategies to mitigate and prevent HIV/AIDS. One of PEPFAR’s strategic principles is to encourage and strengthen faithbased and community-based non-governmental organizations. The identification of sustainable and efficient local NGOs and the capacity building of these partners is the cornerstone on which the effective engagement of local NGOs is built. The goal of this paper is to begin a discussion among donors, international and local NGOs, and multilateral and U.S. government representatives on how to effectively engage indigenous partners and transfer much-needed resources
Assessing the Impacts of Federal Farm Bill Programs on Rural Communities
This report summarizes the state of scientific knowledge on the impact of federal farm and food programs on rural communities in the United States. We focus on the impacts of five specific programs of what is commonly referred to as the “farm bill.” These five include farm commodity programs; farm risk management, insurance, and disaster programs; agricultural conservation programs; food and nutrition programs; and rural development programs. Although there is extensive research on the relative merits and effectiveness of specific rural development programs and policies on rural community outcomes, the impacts of the other four main farm bill programs on rural America have received much less empirical scrutiny
A 15.3 GHz satellite-to-ground diversity propagation experiment using a terminal separation of 4 kilometers
The performance of a path diversity satellite-to-ground millimeter wave link with two ground terminals separated by 4 km is discussed. At this separation distance the duration of fades below 6 dB was decreased by at least a factor of 10 when using path diversity and the cumulative crosscorrelation between the attenuations observed at the two terminals during rain events was approximately 0.45. Narrow beam radiometers directed along the propagation paths were also utilized to relate the path radiometric temperature to the path attenuation. An analysis of downlink propagation data for generating diversity link performance statistics is included
Dipole-dipole instability of atom clouds in a far-detuned optical dipole trap
The effect of the dipole-dipole interaction on the far-off-resonance optical
dipole trapping scheme is calculated by a mean-field approach. The trapping
laser field polarizes the atoms and the accompanying dipole-dipole energy shift
deepens the attractive potential minimum in a pancake-shaped cloud. At high
density the thermal motion cannot stabilize the gas against self-contraction
and an instability occurs. We calculate the boundary of the stable and unstable
equilibrium regions on a two-dimensional phase diagram of the atom number and
the ratio of the trap depth to the temperature. We discuss the limitations
imposed by the dipole-dipole instability on the parameters needed to reach
Bose-Einstein condensation in an optical dipole trap.Comment: 8 pages, 3 figure
A differential genome-wide transcriptome analysis : impact of cellular copper on complex biological processes like aging and development
The regulation of cellular copper homeostasis is crucial in biology. Impairments lead to severe dysfunctions and are known to affect aging and development. Previously, a loss-of-function mutation in the gene encoding the copper-sensing and copper-regulated transcription factor GRISEA of the filamentous fungus Podospora anserina was reported to lead to cellular copper depletion and a pleiotropic phenotype with hypopigmentation of the mycelium and the ascospores, affected fertility and increased lifespan by approximately 60% when compared to the wild type. This phenotype is linked to a switch from a copper-dependent standard to an alternative respiration leading to both a reduced generation of reactive oxygen species (ROS) and of adenosine triphosphate (ATP). We performed a genome-wide comparative transcriptome analysis of a wild-type strain and the copper-depleted grisea mutant. We unambiguously assigned 9,700 sequences of the transcriptome in both strains to the more than 10,600 predicted and annotated open reading frames of the P. anserina genome indicating 90% coverage of the transcriptome. 4,752 of the transcripts differed significantly in abundance with 1,156 transcripts differing at least 3-fold. Selected genes were investigated by qRT-PCR analyses. Apart from this general characterization we analyzed the data with special emphasis on molecular pathways related to the grisea mutation taking advantage of the available complete genomic sequence of P. anserina. This analysis verified but also corrected conclusions from earlier data obtained by single gene analysis, identified new candidates of factors as part of the cellular copper homeostasis system including target genes of transcription factor GRISEA, and provides a rich reference source of quantitative data for further in detail investigations. Overall, the present study demonstrates the importance of systems biology approaches also in cases were mutations in single genes are analyzed to explain the underlying mechanisms controlling complex biological processes like aging and development
Averting Robot Eyes
Home robots will cause privacy harms. At the same time, they can provide beneficial services—as long as consumers trust them. This Essay evaluates potential technological solutions that could help home robots keep their promises, avert their eyes, and otherwise mitigate privacy harms. Our goals are to inform regulators of robot-related privacy harms and the available technological tools for mitigating them, and to spur technologists to employ existing tools and develop new ones by articulating principles for avoiding privacy harms.
We posit that home robots will raise privacy problems of three basic types: (1) data privacy problems; (2) boundary management problems; and (3) social/relational problems. Technological design can ward off, if not fully prevent, a number of these harms. We propose five principles for home robots and privacy design: data minimization, purpose specifications, use limitations, honest anthropomorphism, and dynamic feedback and participation. We review current research into privacy-sensitive robotics, evaluating what technological solutions are feasible and where the harder problems lie. We close by contemplating legal frameworks that might encourage the implementation of such design, while also recognizing the potential costs of regulation at these early stages of the technology
The Balanced Scorecard: The Key to Effective Strategic Management
The intent of this paper is to define the importance of the balanced scorecard in the strategic management process. The need for the balanced scorecard will be established by explaining the roles of demand shifters, traditional management accounting, Senge’s concept of a learning organization, and the strategic management process. This will involve detailing the stages of the strategic management process and connecting them to the various aspects of creating a balanced scorecard. Ultimately, the goal of the balanced scorecard is to translate the overarching strategy into specific actions that can be implemented throughout the organization. Lastly, other strategic applications of the balanced scorecard will be identified and explained
A Real-time Study of Future Temporal Reference in Spoken Ontarian French
In this paper I examine the use of future temporal reference in real-time in the majority French community of Hawkesbury, Ontario, Canada. The corpora, established in 1978 and 2005, contain sociolinguistic interviews of Francophone adolescents 15 to 18 years of age enrolled in French-medium schools. At issue in this research is the variation between the periphrastic and inflected future forms. Over the 28-year time span, the periphrastic future has assumed new prestige in this variety, now the preferred variant of the middle class. Moreover, this form has made significant gains into negative contexts, the formerly privileged and nearly exclusive site of the inflected future. In light of this unprecedented behavior, the question remains as to what will become of the inflected future. I discuss here a number of important signs discovered in the real-time data for Hawkesbury that lend further support for the waning force of the inflected future in Laurentian varieties of spoken French
