Increased Attention (increased + attention)
Selected AbstractsThe Quality of Health Insurance Service Delivery for Kidney Transplant Recipients: A Patient PerspectiveAMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2010E. J. Gordon Increased attention has been devoted to improving quality care in kidney transplantation. The discourse on quality care has focused on transplant center metrics and other clinical parameters. However, there has been little discussion on the quality of health insurance service delivery, which may be critical to kidney recipients' access to transplantation and immunosuppression. This paper describes and provides a framework for characterizing kidney transplant recipients' positive and negative interactions with their insurers. A consecutive cohort of kidney recipients (n = 87) participated in semistructured interviews on their interactions with insurance agencies. Patients reported negative (37%) and/or neutral or positive (79%) interactions with their insurer (a subset [16%] reported both). Perceived negative experiences included: poor service, logistical difficulties with confusing and time-consuming paperwork, poor communication, rude behavior and concerns about adequate coverage. Positive experiences related to: having good coverage, a simple application process, straightforward transactions and helpful communication. Findings suggest that even when patients have insurance coverage, difficult interactions with insurers and limited skills in navigating insurance options may limit their access to needed medications and health services. Future research is needed to test this hypothesis in a larger population. [source] Markers of hepatitis B virus infection and immunity in Victoria, Australia, 1995 to 2005AUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2010Benjamin Cowie Abstract Objective: Estimating the prevalence of chronic hepatitis B virus (HBV) infection in generally low-prevalence populations containing communities with a higher disease burden is difficult. This study was conducted to estimate the prevalence of serological markers of infection with, and immunity to, HBV in the Victorian population and to analyse trends in these estimates over time. Methods: A serological survey of 3,212 samples of convenience collected in the years 1995, 2000 and 2005 was conducted using a selection procedure designed to reduce selection bias. All samples were tested for hepatitis B surface and core antibodies; all core antibody positive samples (indicating previous infection) were then tested for the presence of hepatitis B surface antigen (HBsAg). Results: HBsAg prevalence was 1.1% (95%CI 0.8-1.6%) with significant differences observed by area of residence, age, gender and test year. Serological evidence of immunisation in infants and adolescents were lower than established estimates following the introduction of universal vaccination for these groups. Conclusions: This study emphasises the significant and growing problem of chronic HBV infection in Victoria and suggests lower than expected population immunity deriving from universal vaccination programs. Implications: Greater efforts are needed to formulate a comprehensive public health response to address this relatively neglected blood borne viral infection, the burden of which is very significant in some marginalised sections of our community. Increased attention to improving the universality of our immunisation programs is also needed. [source] Prevalence of habitual refractive errors and anisometropia among Dutch schoolchildren and hospital employeesACTA OPHTHALMOLOGICA, Issue 5 2009Theo J.W. Hendricks Abstract. Purpose:, Refractive error (RE) is suggested to cause not only visual impairment, but also functional problems such as aspecific health complaints and lower levels of school achievement. During the last few decades the prevalence of myopia has increased worldwide, especially in Asia. We investigated the prevalence of habitual RE and anisometropia in a Dutch population of children and employees. Methods:, In a cross-sectional study, RE in both eyes of 520 children (aged 11,13 years) and 444 hospital employees (aged 17,60 years) were measured using an autorefractometer. The measurements were performed without using a cycloplegium. Pearson's correlation coefficient (r) was used to analyse correlations between the right and left eyes. Chi-square tests were used to test the differences between subgroups according to gender and age. Results:, In schoolchildren 28% of right eyes were myopic (> 0.50 D) and 8% hyperopic (> 0.50 D). Pearson's r between right and left eyes for spherical equivalent power (SEP) was 0.93. The mean cylinder deviation in right eyes was 0.26 D (range 0.00,4.50 D). Anisometropia > 1.00 D was present in 4.6% of children; 22% of children were not optimally (> 0.50 D) corrected. In hospital employees, 30% of right eyes were myopic (> 0.50 D) and 10% hyperopic (> 0.50 D). Pearson's r between right and left eyes for SEP was 0.53. The mean cylinder deviation in right eyes was 0.35 D (range 0.00,5.75 D). Anisometropia > 1.00 D was present in 25% of employees. Anisometropia was more frequently present in employees aged 40,60 years, than in those aged 17,39 years (30% versus 18%; p = 0.02, Cramer's V = 0.15). Conclusions:, Refractive errors are common in children aged 11,13 years and in working adults aged 17,60 years. Distributions of sphere and cylinder deviations are similar for Dutch schoolchildren and hospital employees. Surprisingly, anisometropia proved to be more prevalent with age. In children many eyes are not optimally corrected. Increased attention should be paid to uncorrected and miscorrected REs. [source] Biogeographic Crossroads as Priority Areas for Biodiversity ConservationCONSERVATION BIOLOGY, Issue 6 2002Sacha Spector I suggest that targeting the regions where biogeographic assemblages intersect,"biogeographic crossroads",is a strategy that may achieve significant conservation economy by focusing on areas that satisfy many conservation criteria. I used a combination of data on Scarabaeine beetles in Bolivia and on other taxa and locations from the literature to consider the short- and long-term benefits of conserving these biogeographic crossroads. Biogeographic crossroads are areas of high species richness and beta diversity, often across many taxonomic groups. They are also regions where representativeness can be achieved with relative efficiency. Recent evidence that ecotones may be loci of evolution suggests that evolutionary processes such as speciation and coevolution may be conserved at biogeographic crossroads. Biogeographic crossroads appear to be areas of high conservation priority and opportunity in both the short and long term and require increased attention in the process of setting conservation priorities. Resumen: Las amenazas a la biodiversidad rebasan los recursos de la comunidad conservacionista y requieren de una cuidadosa priorización de las acciones de conservación. Sugiero que enfocar en las regiones donde intersectan ensambles biogeográficos,"intersecciones biogeográficas", es una estrategia que puede lograr una economía significativa de los esfuerzos de conservación al atender áreas que satisfacen muchos criterios de conservación. Utilicé una combinación de datos de escarabajos Scarabaeine de Bolivia y de otros taxones y localidades de la literatura para considerar los beneficios a corto y largo plazo de conservar estas intersecciones biogeográficas. Las intersecciones biogeográficas son áreas de alta riqueza de especies y de diversidad beta, y probablemente éste sea el caso de muchos grupos taxonómicos. También son regiones en las que se puede alcanzar representatividad con relativa eficiencia. Evidencia reciente de que los ecotonos pueden ser sitios de evolución sugiere que los procesos evolutivos tales como la especiación y coevolución pueden ser conservados en intersecciones biogeográficas. Las intersecciones biogeográficas parecen ser áreas de alta prioridad y oportunidad de conservación tanto a corto como a largo plazo y requieren mayor atención en el proceso de definición de prioridades de conservación. [source] Ownership and Incentives in Joint Forest Management: A SurveyDEVELOPMENT POLICY REVIEW, Issue 1 2005Tuukka Castrén The relationship between the state and communities has been an overriding issue in the development of forestry institutions globally. In many countries, the trend is for communities to become co-managers of public forests. Meanwhile, in development co-operation both poverty and multiple rural livelihoods have received increased attention. In this article, the potential of joint community-state management of forests is discussed. Forest production has several characteristics that make it suitable for joint management where both parties benefit. Involving communities in management decreases the state's monitoring costs, while communities benefit from better access to market information. For this to take place, however, the state forest apparatus needs to be free from undue rent-seeking. The most advantageous solutions are case- and context-specific. [source] Prediction of twelve-month service disengagement from an early intervention in psychosis serviceEARLY INTERVENTION IN PSYCHIATRY, Issue 3 2007Mark Turner Abstract Aim: The aim is to examine disengagement in an early psychosis treatment service and contrast clinical and demographic variables of patients who disengage against those who do not. Methods: Those with termination of treatment, despite therapeutic need within 12 months of entry (disengagers) (n = 57; 24.6%), were compared with those who remained in treatment at 12 months (n = 175) on a range of clinical and demographic variables collected at admission. After testing the difference between proportions, data analysis was conducted using methods of logistic regression. Results: Alcohol and/or cannabis abuse/dependence, initial diagnosisother than mood disorder, long duration of untreated psychosis, lower Positive and Negative Syndrome Scale total symptoms, and lower insight at referral accounted for 27% of variance in patient ,disengagement' within 12 months. Conclusion: A significant proportion of patients with first episode psychosis disengage from treatment within 12 months. Despite a number of factors being associated with disengagement, prediction using admission factors was poor. Early Intervention in Psychosis Services would benefit from increased attention to alcohol and drug problems, trying to reduce the duration of untreated psychosis, improving psychiatric symptoms and increasing insight in all patients to decrease service disengagement. [source] The role of vegetation patterns in structuring runoff and sediment fluxes in drylandsEARTH SURFACE PROCESSES AND LANDFORMS, Issue 2 2005Juan Puigdefábregas Abstract The dynamics of vegetation-driven spatial heterogeneity (VDSH) and its function in structuring runoff and sediment fluxes have received increased attention from both geomorphological and ecological perspectives, particularly in arid regions with sparse vegetation cover. This paper reviews the recent findings in this area obtained from field evidence and numerical simulation experiments, and outlines their implications for soil erosion assessment. VDSH is often observed at two scales, individual plant clumps and stands of clumps. At the patch scale, the local outcomes of vegetated patches on soil erodibility and hydraulic soil properties are well established. They involve greater water storage capacity as well as increased organic carbon and nutrient inputs. These effects operate together with an enhanced capacity for the interception of water and windborne resources, and an increased biological activity that accelerates breakdown of plant litter and nutrient turnover rates. This suite of relationships, which often involve positive feedback mechanisms, creates vegetated patches that are increasingly different from nearby bare ground areas. By this way a mosaic builds up with bare ground and vegetated patches coupled together, respectively, as sources and sinks of water, sediments and nutrients. At the stand scale within-storm temporal variability of rainfall intensity controls reinfiltration of overland flow and its decay with slope length. At moderate rainfall intensity, this factor interacts with the spatial structure of VDSH and the mechanism of overland flow generation. Reinfiltration is greater in small-grained VDSH and topsoil saturation excess overland flow. Available information shows that VDSH structures of sources and sinks of water and sediments evolve dynamically with hillslope fluxes and tune their spatial configurations to them. Rainfall simulation experiments in large plots show that coarsening VDSH leads to significantly greater erosion rates even under heavy rainfall intensity because of the flow concentration and its velocity increase.

[source] Cultivating Beyond-Capitalist EconomiesECONOMIC GEOGRAPHY, Issue 3 2010Sarah Wright abstract Conceptualizations of the economy as diverse and multiple have garnered increased attention in economic geography in recent years. Against the debilitating mantra of TINA (there is no alternative), these conceptualizations use an ontology of proliferation to insist that many viable and vital alternatives to capitalism do, in fact, exist. I aim to contribute to this project with a close reading of the diverse formal and informal economic practices associated with the village of Puno in the Philippines. In doing so, I respond to calls for work that begins in the majority world and that focuses on the broader political project associated with diverse economies. Research in this area has frequently been critiqued for not paying sufficient attention to the unstable yet persistent exclusions that may endure in, and may even be enhanced by, alternative economies. With this article, I aim to investigate the ways that power relations work through the diverse economies of Puno and the ways that residents act to transform these relations. In doing so, I draw on the experiences of three residents of Puno and their involvement in three social movement organizations. I find that the economy is usefully understood as a site of struggle in which residents work to redefine themselves and the economy. The diverse spaces of their economic lives are neither strictly alternative nor mainstream, inherently oppressive nor radical. Rather, the people of Puno are engaged in willfully cultivating spaces-beyond-capitalism through which they transform the very meaning of economic practice. [source] Understanding anorexia nervosa through analysis of thematic content of letters in an adolescent sampleEUROPEAN EATING DISORDERS REVIEW, Issue 5 2006Glen Freedman Abstract Objective Positive and negative themes about their illness have been identified in an adult population with anorexia nervosa. It was our goal to explore the thematic content of the letters written by an adolescent population in order to better our understanding of how this different population relates to the illness. Method Twenty-seven adolescents with anorexia nervosa were asked to write two letters to their eating disorder, one addressing it as a friend and the other, as an enemy. The coding scheme initially developed by Serpell and Treasure, with minor adjustments, was used to code the letters by two trained raters, with high inter-rater reliability. Results Many similarities and a few notable differences between the adolescent population and an adult population were noted. Compared to an adult population, adolescents valued to a greater degree the sense of feeling looked after by the disorder and the increased attention that they felt the disorder provided. In contrast, they did not view loss of periods as a benefit. Regarding perceived costs of anorexia nervosa, adolescents described a greater degree of psychological distress in relation to the disorder, and a greater sense of having been tricked by the disorder. They did not describe as much frustration with preoccupation with thoughts about food or of being controlled by food. All other themes were not considered appreciably different in terms of percentage of statements or of subjects. Discussion An understanding of how adolescents relate to their illness in terms of themes can help to provide the therapist with a sense of where a patient is in terms of motivation and readiness for recovery. This in turn can aid in the determination of an appropriate treatment approach that is most likely to foster an optimal therapeutic alliance and to enhance motivation to recover.

John Livesley Interest in the interface between normality and psychopathology was renewed with the publication of DSM-III more than 20 years ago. The use of a separate axis to classify disorders of personality brought increased attention to these conditions. At the same time, the definition of personality disorder as inflexible and maladaptive traits stimulated interest in the relationship between normal and disordered personality structure and functioning. The evidence suggests that the traits delineating personality disorder are continuous with normal variation and that the structural relationships among these traits resemble the structures described by normative trait theories. Recognition that personality disorder represents the extremes of trait dimensions emphasizes the importance of differentiating normal, abnormal, and disordered personality. It is argued that while abnormal personality may be considered extreme variation, personality disorder is more than statistical variation. A definition of personality disorder is suggested based on accounts of the adaptive functions of personality. Copyright © 2005 John Wiley & Sons, Ltd. [source] Concurrent assessment of fish and habitat in warmwater streams in WyomingFISHERIES MANAGEMENT & ECOLOGY, Issue 1 2006M. C. QUIST Abstract, Fisheries research and management in North America have focused largely on sport fishes, but native non-game fishes have attracted increased attention due to their declines. The Warmwater Stream Assessment (WSA) was developed to evaluate simultaneously both fish and habitat in Wyoming streams by a process that includes three major components: (1) stream-reach selection and accumulation of existing information, (2) fish and habitat sampling and (3) summarisation and evaluation of fish and habitat information. Fish are sampled by electric fishing or seining and habitat is measured at reach and channel-unit (i.e. pool, run, riffle, side channel, or backwater) scales. Fish and habitat data are subsequently summarised using a data-matrix approach. Hierarchical decision trees are used to assess critical habitat requirements for each fish species expected or found in the reach. Combined measurements of available habitat and the ecology of individual species contribute to the evaluation of the observed fish assemblage. The WSA incorporates knowledge of the fish assemblage and habitat features to enable inferences of factors likely influencing both the fish assemblage and their habitat. The WSA was developed for warmwater streams in Wyoming, but its philosophy, process and conceptual basis may be applied to environmental assessments in other geographical areas. [source] Germans as Venutians: The Culture of German Foreign Policy BehaviorFOREIGN POLICY ANALYSIS, Issue 1 2006AKAN MALICI The end of the Cold War eliminated many of the external constraints that had straitjacketed German policy during the Cold War era. At the same time, unification augmented Germany's already substantial power base. In light of these changed geopolitical circumstances, it was only logical for the dominant theory of security studies, namely realism, to expect a reorientation in German foreign policy behavior toward unilateralism and increased levels of power politics. Yet these expectations proved wrong. This article argues that German foreign policy behavior in the post-Cold War era can be ascribed to a foreign policy culture of reticence,a culture of restraint and accommodation that can be traced to well-defined sets of fundamental beliefs of the German decision-making elite. This article systematically examines these beliefs in the post-Cold War era, relates them to foreign policy choices, and concludes with a plea for increased attention to ideational variables. [source] B,Z DNA Transition Triggered by a Cationic Comb-Type CopolymerADVANCED FUNCTIONAL MATERIALS, Issue 22 2009Naohiko Shimada Abstract The conformational transition from right-handed B,DNA to left-handed Z,DNA,the B,Z transition,has received increased attention recently because of its potential roles in biological systems and its applicability to bionanotechnology. Though the B,Z transition of poly(dG,dC),·,poly(dG,dC) is inducible under high salt concentration conditions (over 4,M NaCl) or by addition of multivalent cations, such as hexaamminecobalt(III), no cationic polymer were known to induce the transition. In this study, it is shown by circular dichroism and UV spectroscopy that the cationic comb-type copolymer, poly(L -lysine)- graft -dextran, but not poly(L -lysine) homopolymer or a basic peptide, induces the B,Z transition of poly(dG,dC),·,poly(dG,dC). At a cationic amino group concentration of 10,4,M the copolymer stabilizes Z,DNA. The transition pathway from the B to the Z form is different to that observed previously. We speculate that the cationic backbone of the copolymer, which reduces electrostatic repulsion among DNA phosphate groups, and the hydrophilic dextran chains, which reduce activity of water, cooperate to induce the B,Z transition. The copolymer specifically modified the micro-environment around DNA molecules to induce Z,DNA formation through stable and spontaneous inter-polyelectrolyte complex formation. [source] Funnel-and-Gate Performance in a Moderately Heterogeneous Flow DomainGROUND WATER MONITORING & REMEDIATION, Issue 3 2001Lacrecia C. Bilbrey The funnel-and-gate ground water remediation technology (Starr and Cherry 1994) has received increased attention and application as an in situ alternative to the typical pump-and-treat system. Understanding the effects of heterogeneity on system performance can mean the difference between a successful remediation project and one that fails to meet its cleanup goals. In an attempt to characterize and quantify the effects of heterogeneity on funnel-and-gate system performance, a numerical modeling study of 15 simulated heterogeneous flow domains was conducted. Each realization was tested to determine if the predicted capture width met the capture width expected for a homogeneous flow domain with the same hulk properties. This study revealed that the capture width of the funnel-and-gate system varied significantly with the level of heterogeneity of the aquifer. Two possible remedies were investigated for bringing systems with less than acceptable capture widths to acceptable levels of performance. First, it was determined that enlarging the funnel and gate via a factor of safety applied to the design capture width could compensate for the capture width variation in the heterogeneous flow domains. In addition, it was shown that the use of a pumping well downstream of the funnel and gate could compensate for the effects of aquifer heterogeneity on the funnel-and-gate capture width. However, if a pumping well is placed downstream of the funnel and gate to control the hydraulic gradient through the gate, consideration should be given to the gate residence time in relation to the geochemistry of the contaminant removal or destruction process in the gate. [source] Re-Forging the ,Age of Iron' Part II: The Tenth Century in a New Age?HISTORY COMPASS (ELECTRONIC), Issue 9 2010John Howe The tenth century, once dismissed as an unpleasant ,Age of Iron', now receives increased attention as an important age of transition. Historians are attempting to understand how it fits into the broader narrative of Western Civilization. Although some scholars have identified it as the last act of the post-Roman world, others see it as a new age. Perhaps the High Middle Ages with its agricultural and demographic revolution, its new villages and parishes, its revived cities, its reformed churches and schools, and its medieval monarchs began in the tenth century? Or were those changes not novelties of the tenth century but rather manifestations of a ,take off' that had already begun back in the Carolingian Empire, and which, despite the problems posed by late Carolingian wars and invasions, was able to continue, spread, and blossom into the growth and prosperity of the High Middle Ages? New scholarly interest in the tenth century has made it much less of a ,dark age', but scholars still are not quite certain how to conceptualize its historical significance. [source] The Christian Religion in Modern European and World History: A Review of The Cambridge History of Christianity, 1815,2000HISTORY COMPASS (ELECTRONIC), Issue 6 2008David Lindenfeld Volumes 8 and 9 of the Cambridge History, representing the work of 72 scholars, reflect two major recent historiographical trends: 1) the increased attention paid to religion in modern European history, and 2) the increasing importance of Christianity in as a topic in world history. While these volumes serve to summarize the work already done in the first field, with articles on a wide variety of European countries, they should significantly move the second field forward by bringing together the work of specialists on many different parts of the world in a single place. Volume 8 summarizes scholarship on the Western religious revivals of the nineteenth century, both Catholic and Protestant. By integrating religion and politics, it also presents a more complex picture of the formation of European national identities than Benedict Anderson's Imagined Communities suggests. One third of the volume is devoted to the spread of Christianity to the non-Western world. In Volume 9, the European and world history perspectives are more evenly interspersed. Major themes include the papacy, ecumenism, colonialism, Pentecostalism, and the independent churches of Africa and Asia. The 1960s emerge as a turning point, if for different reasons in different parts of the world. This was the decisive period of secularization in Europe, and the final section documents the social and cultural impact of that shift, particularly on the arts. Although there are inevitable gaps in coverage, these volumes will serve as an invaluable research tool for years to come. [source] Does assessment make a difference for people with dementia?INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 3 2003The effectiveness of the Aged Care Assessment Teams in Australia Abstract The needs of individuals with dementia and other psychiatric problems of old age have received increased attention in Australia over the last decade. This paper reports on the role of Aged Care Assessment Teams (ACATs) in managing these clients, and the extent to which they are differentiated from other clients in the assessment process and outcomes recommended. Data on some 26,500 clients seen by ACATs in Victoria in the second half of 1999 are analysed to show (1) the relationship between a diagnosis of dementia and reporting of disability in orientation, (2) characteristics of clients with and without a diagnosis of dementia and (3) outcomes for groups of clients defined on the basis of a diagnosis of dementia and disability in orientation.

Guttentag Abstract Volunteer tourism is an increasingly popular form of travel that is attracting growing research attention. Nevertheless, existing research has focused primarily on the benefits of volunteer tourism, and many studies have simply involved profiling volunteers or investigating their motivations. However, there are numerous possible negative impacts of volunteer tourism that deserve increased attention from both researchers and project managers: a neglect of locals' desires, a hindering of work progress and completion of unsatisfactory work, a disruption of local economies, a reinforcement of conceptualisations of the ,other' and rationalisations of poverty, and an instigation of cultural changes. Copyright © 2009 John Wiley & Sons, Ltd. [source] Human Rights of Migrants: Challenges of the New DecadeINTERNATIONAL MIGRATION, Issue 6 2001Patrick A. Taran This review summarizes main trends, issues, debates, actors and initiatives regarding recognition and extension of protection of the human rights of migrants. Its premise is that the rule of law and universal notions of human rights are essential foundations for democratic society and social peace. Evidence demonstrates that violations of migrants' human rights are so widespread and commonplace that they are a defining feature of international migration today. About 150 million persons live outside their countries; in many States, legal application of human rights norms to non-citizens is inadequate or seriously deficient, especially regarding irregular migrants. Extensive hostility against, abuse of and violence towards migrants and other non-nationals has become much more visible worldwide in recent years. Research, documentation and analysis of the character and extent of problems and of effective remedies remain minimal. Resistance to recognition of migrants' rights is bound up in exploitation of migrants in marginal, low status, inadequately regulated or illegal sectors of economic activity. Unauthorized migrants are often treated as a reserve of flexible labour, outside the protection of labour safety, health, minimum wage and other standards, and easily deportable. Evidence on globalization points to worsening migration pressures in many parts of the world. Processes integral to globalization have intensified disruptive effects of modernization and capitalist development, contributing to economic insecurity and displacement for many. Extension of principles in the Universal Declaration of Human Rights culminated in the 1990 International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families. With little attention, progress in ratifications was very slow until two years ago. A global campaign revived attention; entry into force is likely in 2001. Comparative analysis notes that ILO migrant worker Conventions have generally achieved objectives but States have resisted adoption of any standards on treatment of non-nationals. A counter-offensive against human rights as universal, indivisible and inalienable underlies resistance to extension of human rights protection to migrants. A parallel trend is deliberate association of migration and migrants with criminality. Trafficking has emerged as a global theme contextualizing migration in a framework of combatting organized crime and criminality, subordinating human rights protections to control and anti-crime measures. Intergovernmental cooperation on migration "management" is expanding rapidly, with functioning regional intergovernmental consultative processes in all regions, generally focused on strengthening inter-state cooperation in controlling and preventing irregular migration through improved border controls, information sharing, return agreements and other measures. Efforts to defend human rights of migrants and combat xenophobia remain fragmented, limited in impact and starved of resources. Nonetheless, NGOs in all regions provide orientation, services and assistance to migrants, public education and advocating respect for migrants rights and dignity. Several international initiatives now highlight migrant protection concerns, notably the UN Special Rapporteur on Human Rights of Migrants, the Global Campaign promoting the 1990 UN Convention, UN General Assembly proclamation of International Migrants Day, the 2001 World Conference Against Racism and Xenophobia, anti-discrimination activity by ILO, and training by IOM. Suggestions to governments emphasize the need to define comprehensive, coordinated migration policy and practice based on economic, social and development concerns rather than reactive control measures to ensure beneficial migration, social harmony, and dignified treatment of nationals and non-nationals. NGOs, businesses, trade unions, and religious groups are urged to advocate respect for international standards, professionalize services and capacities, take leadership in opposing xenophobic behaviour, and join international initiatives. Need for increased attention to migrants rights initiatives and inter-agency cooperation by international organizations is also noted. [source] Potentially Avoidable Hospitalizations of Nursing Home Residents: Frequency, Causes, and CostsJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 4 2010[See editorial comments by Drs. OBJECTIVES: To examine the frequency and reasons for potentially avoidable hospitalizations of nursing home (NH) residents. DESIGN: Medical records were reviewed as a component of a project designed to develop and pilot test clinical practice tools for reducing potentially avoidable hospitalization. SETTING: NHs in Georgia. PARTICIPANTS: In 10 NHs with high and 10 with low hospitalization rates, 10 hospitalizations were randomly selected, including long- and short-stay residents. MEASUREMENTS: Ratings using a structured review by expert NH clinicians. RESULTS: Of the 200 hospitalizations, 134 (67.0%) were rated as potentially avoidable. Panel members cited lack of on-site availability of primary care clinicians, inability to obtain timely laboratory tests and intravenous fluids, problems with quality of care in assessing acute changes, and uncertain benefits of hospitalization as causes of these potentially avoidable hospitalizations. CONCLUSION: In this sample of NH residents, experienced long-term care clinicians commonly rated hospitalizations as potentially avoidable. Support for NH infrastructure, clinical practice and communication tools for health professionals, increased attention to reducing the frequency of medically futile care, and financial and other incentives for NHs and their affiliated hospitals are needed to improve care, reduce avoidable hospitalizations, and avoid unnecessary healthcare expenditures in this population. [source] Morgan Stanley Roundtable on Private Equity and Its Import for Public CompaniesJOURNAL OF APPLIED CORPORATE FINANCE, Issue 3 2006Article first published online: 4 OCT 200 The role of private equity in global capital markets appears to be expanding at an extraordinary rate. Morgan Stanley estimates that there are now some 2,700 private equity funds that either have raised, or are in the process of raising, a total of $500 billion. With this abundance of available equity capital, the willingness of private equity firms to participate in "club" deals, and the leverage that can be put on top of the equity, private equity buyers now appear able and willing to pay higher prices for assets than ever before. And thanks in part to this new purchasing power, private equity transactions reportedly account for a quarter of all global M&A activity as well as a third of the high yield and IPO markets. The stock of capital now devoted to private equity reflects the demonstrated ability of at least the most reputable buyout firms to produce consistently high rates of returns for their limited partners. Although a talent for identifying and purchasing undervalued assets may be part of the story, the ability to produce such returns on a consistent basis implies an ability to add value, to improve the performance of the operating companies they invest in and control. And in this round-table, a small group of academics and practitioners address two main questions: How does private equity add value? And are there lessons for public companies in the success of private companies? According to the panelists, the answer to the first question appears to have changed somewhat over time. The consensus was that most of the value added by the LBO firms of the,80s was created during the initial structuring of the deals, a process described by Steve Kaplan as "financial and governance engineering," which includes not only aggressive use of leverage and powerful equity incentives for operating managements, but active oversight by a small, intensely interested board of directors. In the past ten years, however, these standard LBO features have been complemented by increased attention to "operational engineering," to the point where today's buyout firms feel obligated, like classic venture capitalists, to acquire and tout their own operating expertise. In response to the second of the two questions, Michael Jensen argues that much of the approach and benefits of private equity-particularly the adjustments of financial policies and stronger managerial incentives-can be replicated by public companies. And although some of these benefits have already been realized, much more remains to be done. Perhaps the biggest challenge, however, is finding a way to transfer to public companies the board-level expertise, incentives, and degree of engagement that characterize companies run by private equity investors. [source] How Many Women Have Osteoporosis?JOURNAL OF BONE AND MINERAL RESEARCH, Issue 5 2005L. Joseph Melton III Osteoporosis is widely viewed as a major public health concern, but the exact magnitude of the problem is uncertain and likely to depend on how the condition is defined. Noninvasive bone mineral measurements can be used to define a state of heightened fracture risk (osteopenia), or the ultimate clinical manifestation of fracture can be assessed (established osteoporosis). If bone mineral measurements more than 2 standard deviations below the mean of young normal women represent osteopenia, then 45% of white women aged 50 years and over have the condition at one or more sites in the hip, spine, or forearm on the basis of population-based data from Rochester, Minnesota. A smaller proportion is affected at each specific skeletal site: 32% have bone mineral values this low in the lumbar spine, 29% in either of two regions in the proximal femur, and 26% in the midradius. Although this overall estimate is substantial, some other serious chronic diseases are almost as common. More importantly, low bone mass is associated with adverse health outcomes, especially fractures. The lifetime risk of any fracture of the hip, spine, or distal forearm is almost 40% in white women and 13% in white men from age 50 years onward. If the enormous costs associated with these fractures are to be reduced, increased attention must be given to the design and implementation of control programs directed at this major health problem.

One class of multivariate hypotheses, founded in successional diversity theory, predict that species richness is jointly influenced by periodic disturbances that create new niche opportunities in space or time, and the production of community biomass that speeds displacement of inferior by superior competitors. 2While the joint response of diversity to disturbance and productivity has gained support from theoretical and small-scale experimental studies, evidence that corresponding patterns of biodiversity occur broadly across natural systems is scarce. 3Using a data set that employed standardized methods to sample 85 streams throughout the mid-Atlantic United States of America, we show that biogeographical patterns of primary producer diversity in stream ecosystems are consistent with the predictions of a multivariate model that incorporates disturbance frequency and community biomass production as independent variables. Periphyton species richness is a concave-down function of disturbance frequency (mean no. floods year,1) and of biomass production (µg of biomass accrual cm,2 day,1), and an increasing function of their interaction. 4Changes in richness across the disturbance × productivity response surface can be related to several predicted life-history traits of the dominant species. 5Our findings complement prior studies by showing that multivariate models which consider interactive effects of community production and ecosystem disturbance are, in fact, candidate explanations of much broader patterns of richness in natural systems. Because multivariate models predict synergistic effects of ecological variables on species diversity, human activities , which are simultaneously altering both the disturbance regime and productivity of streams , could be influencing biodiversity more than previously anticipated.

Brandt Abstract A large number of N,N -dialkylated tryptamines are known to induce psychoactive effects in humans. This has resulted in their increased attention within clinical and forensic communities. Deuterated tryptamines are ideal for use as internal standards during MS bioanalysis or of use in biochemical NMR studies. The present study reports on a microwave-enhanced synthesis of 22 N,N -dialkylated-[,,,,,,, -d4]-tryptamines via the reduction with lithium aluminium deuteride of glyoxalylamide precursors obtained by the procedure of Speeter and Anthony. Syntheses were carried out using a single-mode system under elevated pressure conditions where anhydrous tetrahydrofuran was used as the solvent at 150°C. Good yields were obtained within 5,min.

[source] Supporting inquiry learning by promoting normative understanding of multivariable causalityJOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 9 2003Alla Keselman Early adolescents may lack the cognitive and metacognitive skills necessary for effective inquiry learning. In particular, they are likely to have a nonnormative mental model of multivariable causality in which effects of individual variables are neither additive nor consistent. Described here is a software-based intervention designed to facilitate students' metalevel and performance-level inquiry skills by enhancing their understanding of multivariable causality. Relative to an exploration-only group, sixth graders who practiced predicting an outcome (earthquake risk) based on multiple factors demonstrated increased attention to evidence, improved metalevel appreciation of effective strategies, and a trend toward consistent use of a controlled comparison strategy. Sixth graders who also received explicit instruction in making predictions based on multiple factors showed additional improvement in their ability to compare multiple instances as a basis for inferences and constructed the most accurate knowledge of the system. Gains were maintained in transfer tasks. The cognitive skills and metalevel understanding examined here are essential to inquiry learning. © 2003 Wiley Periodicals, Inc.

In this study, a new technique for continuously preparing a filled type of PGM was investigated through co-extrusion/gradient distribution/2-dimensional mixing with conventional polymeric material processing facilities. The processing line from co-extrusion, gradient distribution to 2-dimensional mixing was fulfilled by two extruders, a gradient distribution unit and 2-dimensional mixing units. The gradient distribution unit and 2-dimensional mixing units were designed separately in our group. As an example, a PE/GB PGM was prepared by using this new technique. The gradient variation of composition along the sample thickness direction was studied by TG and SEM. The TG results indicated that a gradient variation of the content of GB was formed along the thickness of the sample. The direct gradient distribution of GB came from SEM observation, which showed an increased stacking density of GB along the sample thickness. Experimental results indicated that the processing method with co-extrusion/gradient distribution/2-dimensional mixing can serve as a new way to produce a filled type of PGM and is worthy of further investigation.

[source] Carbocationic Polymerizations for Profit and FunMACROMOLECULAR SYMPOSIA, Issue 1 2004Ralf M. Peetz Abstract This presentation consists of two largely independent parts: The first åfor Profit, part concerns a bird's eye view of recently commercialized carbocationic processes and materials created by these processes in the author's laboratories whose marketing started during the past ,5 years by various companies. These materials/processes include liquid telechelic polyisobutylene (PIB) for architectural sealants, poly(styrene- b -isobutylene- b -styrene) (PSt- b -PIB- b -PSt) triblocks for thermoplastic elastomers, PIB/PSt-based blocks for coating of medical devices, and PIB-based microemulsions for surface protection of painted metal surfaces. It is concluded that in order to enhance and solidify research in polymer synthesis it would behoove the scientific community to pay increased attention to intellectual property protection. Appropriately managed patenting and publishing activities are self-reinforcing and may be quite profitable. The second "for Fun" part concerns a brief review of the design, synthesis and characterization of two novel fully aliphatic star-block copolymers: ,(PIB- b -PNBD)3 and ,(PNBD- b -PIB)3 (where PNBD = polynorbornadiene). The constituent moieties of these star-blocks are identical except their block sequences are reversed. Motivation for the synthesis of ,(PIB- b -PNBD)3, consisting of a low Tg (,-73°C) PIB inner-corona attached to a high Tg (,320°C) PNBD outer corona, was the expectation that this star-block would exhibit thermoplastic elastomer characteristics, and that it could be used in applications where similar polyaromatic-based TPEs cannot be employed (e.g., magnetic signal storage). The other star-block, ,(PNBD- b -PIB)3, comprises the same building blocks with the PIB and PNBD sequences reversed. We found that the secondary chlorine at the PNBD chain end, in conjunction with TiCl4, is able to initiate the polymerization of isobutylene. Details of the carbocationic polymerization of NBD, together with the microstructure of PNBD, will be discussed. [source] Population structure and intraspecific aggression in the invasive ant species Anoplolepis gracilipes in Malaysian BorneoMOLECULAR ECOLOGY, Issue 7 2007JOCHEN DRESCHER Abstract Invasive species are one of the main sources of the ongoing global loss of biodiversity. Invasive ants are known as particularly damaging invaders and their introductions are often accompanied by population-level behavioural and genetic changes that may contribute to their success. Anoplolepis gracilipes is an invasive ant that has just recently received increased attention due to its negative impact on native ecosystems. We examined the behaviour and population structure of A. gracilipes in Sabah, Malaysia. A total of 475 individuals from 24 colonies were genotyped with eight microsatellite markers. Intracolonial relatedness was high, ranging from 0.37 to 1 (mean ± SD: 0.82 ± 0.04), while intercolonial relatedness was low (0.0 ± 0.02, range ,0.5,0.76). We compared five distinct sampling regions in Sabah and Brunei. A three-level hierarchical F-analysis revealed high genetic differentiation among colonies within the same region, but low genetic differentiation within colonies or across regions. Overall levels of heterozygosity were unusually high (mean HO = 0.95, mean HE = 0.71) with two loci being entirely heterozygous, indicating an unusual reproductive system in this species. Bioassays revealed a negative correlation between relatedness and aggression, suggesting kinship as one factor facilitating supercolony formation in this species. Furthermore, we genotyped one individual per nest from Sabah (22 nests), Sarawak (one nest), Brunei (three nests) and the Philippines (two nests) using two mitochondrial DNA markers. We found six haplotypes, two of which included 82.1% of all sequences. Our study shows that the sampled area in Sabah consists of a mosaic of differently interrelated nests in different stages of colony establishment. While some of the sampled colonies may belong to large supercolonies, others are more likely to represent recently introduced or dispersed propagules that are just beginning to expand. [source] The national question: sociological reflections on nation and nationalismNATIONS AND NATIONALISM, Issue 3 2001Andrew Thompson The sociology of nation, national identity and nationalism has long been the subject of benign neglect. After examining the few positive contributions made by classical writers, we attempt to explain why the contribution of classical theory to the field is unreliable. In common with others we find that, for all that classical theory might treat the prominence of nation, national identity and nationalism as a passing phase, it in fact takes the existence of all three as givens to such an extent that they and their effects become invisible. But the sociology of nation and nationalism reached a turning point with the publication of Elie Kedourie's influential work in 1960. We explain the effect of this work on later writers, especially Ernest Gellner and Anthony Smith, and survey the work of these and other contributors to the field with an eye to their differences and similarities. We identify various stages in the development of the sociology of nation and nationalism, culminating in the most recent stage in which the significance of the subjective aspects of nationalism has received increased attention. We think there is room for a multiplicity of approaches to the subject and stress its central significance to sociology. We explain why nation, national identity and nationalism are certainly not in decline and suggest where the most fruitful lines of inquiry lie for future research.
