U.S. Intelligence Reform A Bureaucratic Politics Approach
This study investigates the current bureaucratic struggles that exist within the U.S. intelligence community as a result of the Intelligence Reform and Terrorism Prevention Act (IRTPA) of 2004. The first part of this research examines the history of intelligence reform in the United States beginning with the National Security Act of 1947. The second part provides an indepth discussion of the 2004 legislation as well as an examination of the main bureaucratic conflicts that have arisen between the Director of National Intelligence (DNI) and the rest of the U.S. intelligence community. This study used the bureaucratic politics model to explain the development of the current disagreements, the reasons behind the DNIâs struggle for power, and the intelligence communityâs inability to adapt to the reform. This research determined that the current conflicts have occurred as a result of the unclear authorities issued to the DNI by IRTPA and have been further exacerbated by interest-driven intelligence agencies and a well-developed culture that has proven difficult to abandon. This research also provides insight into several alternative approaches that can be used to explain the current U.S. intelligence reform process. Additionally, recommendations were made for reducing the bureaucratic friction that currently exists within the intelligence community and to strengthen the overall authority of the Director of National Intelligence

A video life-world approach to consultation practice: The relevance of a socio-phenomenological approach
This article discusses the [development and] use of a video life-world schema to explore alternative orientations to the shared health consultation. It is anticipated that this schema can be used by practitioners and consumers alike to understand the dynamics of videoed health consultations, the role of the participants within it and the potential to consciously alter the outcome by altering behaviour during the process of interaction. The study examines health consultation participation and develops an interpretative method of analysis that includes image elicitation (via videos), phenomenology (to identify the components of the analytic framework), narrative (to depict the stories of interactions) and a reflexive mode (to develop shared meaning through a conceptual framework for analysis). The analytic framework is derived from a life-world conception of human mutual shared interaction which is presented here as a novel approach to understanding patient-centred care. The video materials used in this study were derived from consultations in a Walk-in Centre (WiC) in East London. The conceptual framework produced through the process of video analysis is comprised of different combinations of movement, knowledge and emotional conversations that are used to classify objective or engaged WiC health care interactions. The videoed interactions organise along an active or passive, facilitative or directive typical situation continuum illustrating different kinds of textual approaches to practice that are in tension or harmony. The schema demonstrates how practitioners and consumers interact to produce these outcomes and indicates the potential for both consumers and practitioners to be educated to develop practice dynamics that support patient-centred care and impact on health outcomes
Resistance to Elsinoë Ampelina and Expression of Related Resistant Genes in Vitis Rotundifolia Michx. Grapes
Muscadine grapes (Vitis rotundifolia Michx) are considered as excellent genetic resources for grape breeding programs as they are known for their hardiness and resistance to pests and diseases. However, contrary to popular belief, our study indicated that not all muscadine cultivars are resistant to anthracnose disease. In order to identify a source of genetic tolerance towards anthracnose among muscadine cultivars, a series of in-situ and ex-situ experiments were conducted through strict and sensitive screening processes. Two consecutive years of field evaluation of 54 grape cultivars showed various levels of anthracnose incidence among the cultivars between a scale of 0 (tolerant) to 5 (highly-susceptible). Resistance bioassay by inoculation of different spore densities of Elsinoë ampelina on 40 cultivars presented similar results and was consistent with those obtained from the field test. A real-time PCR analysis was conducted to investigate differences of gene expression between susceptible and tolerant cultivars and to confirm results by phenotypic identification. Expression of genes encoding chalcone synthase, stilbene synthase, polygalacturonase-inhibiting protein, chitinase and lipid transfer-protein was only detected in tolerant cultivars. Resistant muscadine cultivars identified in this study could be excellent candidates for grape disease resistance breeding programs
Assessing the Effects of Personal Characteristics and Context on U.S. House Speakersâ Leadership Styles, 1789-2006
Research on congressional leadership has been dominated in recent decades by contextual interpretations that see leadersâ behavior as best explained by the environment in which they seek to exercise leadershipâparticularly, the preference homogeneity and size of their party caucus. The role of agency is thus discounted, and leadersâ personal characteristics and leadership styles are underplayed. Focusing specifically on the speakers of the U.S. House of Representatives from the first to the 110th Congress, we construct measures of each speakerâs commitment to comity and leadership assertiveness. We find the scores reliable and then test the extent to which a speakerâs style is the product of both political context and personal characteristics. Regression estimates on speakersâ personal assertiveness scores provide robust support for a context-plus-personal characteristics explanation, whereas estimates of their comity scores show that speakersâ personal backgrounds trump context
