[source] Emerging trends in the treatment of rapid cycling bipolar disorder: a selected reviewBIPOLAR DISORDERS, Issue 4 2000Robert M Post Recent evidence suggests that lithium therapy (even as supplemented by antidepressants and neuroleptics) is inadequate for the majority of patients with bipolar illness, and particularly those with rapid cycling. Valproate and carbamazepine have emerged as adjuncts and alternatives, but they, too, often require additional approaches with lithium, thyroid hormones, and other putative mood stabilizers, including nimodipine (and related dihydropyridine calcium channel blockers), lamotrigine, gabapentin, topiramate, and the atypical neuroleptics. Evaluating how these agents and the unimodal antidepressants are optimally applied and sequenced in the treatment of bipolar illness with its multiple subtypes, patterns and comorbidities will require much future investigation and the development of new methodological clinical trial approaches. [source] Towards virtualized desktop environmentCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 4 2010Xiaofei Liao Abstract Virtualization is being widely used now as an emerging trend. Rapid improvements in network bandwidth, ubiquitous security hazards and high total cost of ownership of personal computers have created a growing market for desktop virtualization. Much like server virtualization, virtualizing desktops involves separating the physical location of a client device from its logical interface. But, the performance and usability of some traditional desktop frameworks do not satisfy end-users. Other solutions, including WebOS, which needs to rebuild all daily-used applications into Client/Server mode, cannot be easily accepted by people in a short time. We present LVD, a system that combines the virtualization technology and inexpensive personal computers (PCs) to realize a lightweight virtual desktop system. Comparing to the previous desktop systems, LVD builds an integrated novel desktop environment, which can support the backup, mobility, suspending and resuming of per-user's working environment, and support synchronous using of incompatible applications on different platforms and achieves great saving in power consumption. We have implemented LVD in a cluster with Xen and compared its performance against widely used commercial approaches, including Microsoft RDP, Citrix MetaFrameXP and Sun Ray. Experimental results demonstrate that LVD is effective in performing the functions while imposing little overhead. Copyright © 2009 John Wiley & Sons, Ltd. [source] UNDERSTANDING TRADITIONALIST OPPOSITION TO MODERNIZATION: NARRATIVE PRODUCTION IN A NORWEGIAN MOUNTAIN CONFLICTGEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 1 2008Tor A. Benjaminsen ABSTRACT. In Gausdal, a mountainous community in southern Norway, a conflict involving dogsledding has dominated local politics during the past two decades. In order to understand local protests against this activity, in this article we apply discourse analysis within the evolving approach of political ecology. In this way, we also aim at contributing to the emerging trend of bringing political ecology "home". To many people, dogsledding appears as an environmentally friendly outdoor recreation activity as well as a type of adventure tourism that may provide new income opportunities to marginal agricultural communities. Hence, at a first glance, the protests against this activity may be puzzling. Looking for explanations for these protests, this empirical study demonstrates how the opposition to dogsledding may be understood as grounded in four elements of a narrative: (1) environmental values are threatened; (2) traditional economic activities are threatened; (3) outsiders take over the mountain; and (4) local people are powerless. Furthermore, we argue that the narrative is part of what we see as a broader Norwegian "rural traditionalist discourse". This discourse is related to a continued marginalization of rural communities caused by increasing pressure on agriculture to improve its efficiency as well as an "environmentalization" of rural affairs. Thus, the empirical study shows how opposition to dogsledding in a local community is articulated as a narrative that fits into a more general pattern of opposition to rural modernization in Norway as well as internationally. [source] Instream Flow Science For Sustainable River Management,JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 5 2009Geoffrey E Petts Abstract:, Concerns for water resources have inspired research developments to determine the ecological effects of water withdrawals from rivers and flow regulation below dams, and to advance tools for determining the flows required to sustain healthy riverine ecosystems. This paper reviews the advances of this environmental flows science over the past 30 years since the introduction of the Instream Flow Incremental Methodology. Its central component, Physical HABitat SIMulation, has had a global impact, internationalizing the e-flows agenda and promoting new science. A global imperative to set e-flows, including an emerging trend to set standards at the regional scale, has led to developments of hydrological and hydraulic approaches but expert judgment remains a critical element of the complex decision-making process around water allocations. It is widely accepted that river ecosystems are dependent upon the natural variability of flow (the flow regime) that is typical of each hydro-climatic region and upon the range of habitats found within each channel type within each region. But as the sophistication of physical (hydrological and hydraulic) models has advanced emerging biological evidence to support those assumptions has been limited. Empirical studies have been important to validate instream flow recommendations but they have not generated transferable relationships because of the complex nature of biological responses to hydrological change that must be evaluated over decadal time-scales. New models are needed to incorporate our evolving knowledge of climate cycles and morphological sequences of channel development but most importantly we need long-term research involving both physical scientists and biologists to develop new models of population dynamics that will advance the biological basis for 21st Century e-flow science. [source] STOCK LEVELS AND DELIVERY RATES IN VENDORMANAGED INVENTORY PROGRAMSPRODUCTION AND OPERATIONS MANAGEMENT, Issue 1 2001BEN A. CHAOUCH Using the latest information technology, powerful retailers like Wal-Mart have taken the lead in forging shorter replenishment-cycles, automated supply systems with suppliers. With the objective to reduce cost, these retailers are directing suppliers to take full responsibility for managing stocks and deliveries. Suppliers' performance is measured according to how often inventory is shipped to the retailer, and how often customers are unable to purchase the product because it is out of stock. This emerging trend also implies that suppliers are absorbing a large part of the inventory and delivery costs and, therefore, must plan delivery programs including delivery frequency to ensure that the inherent costs are minimized. With the idea to incorporate this shift in focus, this paper looks at the problem facing the supplier who wants quicker replenishment at lower cost. In particular, we present a model that seeks the best trade-off among inventory investment, delivery rates, and permitting shortages to occur, given some random demand pattern for the product. The process generating demand consists of two components: one is deterministic and the other is random. The random part is assumed to follow a compound Poisson process. Furthermore, we assume that the supplier may fail to meet uniform shipping schedules, and, therefore, uncertainty is present in delivery times. The solution to this transportationinventory problem requires determining jointly delivery rates and stock levels that will minimize transportation, inventory, and shortage costs. Several numerical results are presented to give a feel of the optimal policy's general behavior. [source] The promise of the Internet for disability: a study of on-line services and web site accessibility at Centers for Independent Living,BEHAVIORAL SCIENCES & THE LAW, Issue 1 2003Heather Ritchie M.S.W. The Internet provides individuals with disabilities numerous tools to live independently. In the convenience of the home, a person can access an abundance of information, an electronic community, updates on the latest disability advocacy news, education through distance-learning classes, and on-line shopping for books, clothes, assistive technology, and a host of other consumer goods. Centers for Independent Living (CILs) are consumer-run, non-profit grassroots disability service organizations at the forefront of the disability rights movement. Providing services to individuals across the range of disabilities, CILs have begun to use the Internet as a complement to their traditional service delivery methods. This article examines the emerging trend of independent living services on the web. The investigation examines 200 CIL Internet sites across the United States during the period of April to August 2001. Information is collected and analyzed about how CILs are using the Internet to provide their services and programs. In addition, the article examines the technological accessibility of their web sites. Implications of the findings for CILs, consumers with disabilities, and disability policy are examined.

[source] Internet use for corporate environmental reporting: current challenges,technical benefits,practical guidanceBUSINESS STRATEGY AND THE ENVIRONMENT, Issue 3 2002Ralf Isenmann The huge opportunities of using the internet for corporate reporting are arranged in a comprehensive system of technical benefits. In order to give a tangible example and describe practical use thoroughly, the benefits are focused on environmental reporting but they can be transferred in major parts also to financial, social or sustainability reporting,seen as a currently emerging trend towards integrated financial, environmental and social reporting. In more detail, the system of internet-specific benefits is illustrated by four main categories: benefits concerning the underlying purposes of publishing reports, benefits concerning the entire reporting process, benefits concerning the report contents and benefits concerning the report design. In terms of corporate reporting, professional internet use will enhance the way in which companies give information, communicate and manage their business internally and externally, benefiting all members involved that are reporting companies, addressed key target groups and other stakeholders such as standard setting institutions and benchmarking organizations.

[source] Patterns and correlates of substance use amongst juvenile detainees in New South Wales 1989,99DRUG AND ALCOHOL REVIEW, Issue 1 2003JAN COPELAND Abstract In the decade 1989,99 there have been significant changes in the patterns of substance use in the Australian community. Juvenile offenders have been a sentinel population of these emerging trends. The social and personal costs associated with adolescent substance use, especially where it leads to increased criminal offending requires urgent attention. This study was a replication of the 1989 and 1994 surveys of young people in detention in New South Wales, Australia. The 300 voluntary participants from nine detention centres had a similar demographic profile to participants of the previous surveys. They were predominantly male (90%) with a mean age of 16.5 years and an over-representation of Aboriginal and Torres Straits Islander peoples. The patterns of lifetime alcohol and tobacco use were stable over the decade, with particular increases in amphetamine, opioid and cocaine use since 1994. The more concerning pattern of at least weekly substance use revealed significant increases in cannabis, opioid and cocaine use since 1994, but a significant decrease in the frequent use of alcohol. This study also reports on high levels of negative health and psychosocial consequences of substance use, including overdose, among this group. High levels of self-reported depression and suicidal behaviours, family and gender issues are also discussed. Encouragingly, there was a relatively high level of self-recognized treatment need for substance use and mental health problems among the sample. This highlights further the growing need for the development and dissemination of novel interventions that harness this willingness and actively engage, motivate and maintain these young people in accessible, appropriate and effective interventions. [source] Show Us the Money: Lessons in Transparency from State Pharmaceutical Marketing Disclosure LawsHEALTH SERVICES RESEARCH, Issue 1 2010Susan Chimonas Objective. To assess legislation requiring drug companies to report gifts to providers, and to evaluate the information obtained. Data Sources. Data included legislation in Vermont, Minnesota, Maine, Massachusetts, West Virginia, and the District of Columbia, and company disclosure data from Vermont. Study Design. We evaluated the strengths and weaknesses of state legislation. We also analyzed 4 years of company disclosures from Vermont, assessing the value and distribution of industry,provider exchanges and identifying emerging trends in companies' practices. Data Collection Methods. State legislation is publically available. We obtained Vermont's data through requests to the state's Attorney General's office. Principal Findings. Of the state laws, only Vermont's yielded robust, publically available data. These data show gifting was dominated by a few major corporations, and <2 percent of Vermont's prescribers received 69 percent of gifts and payments. Companies were especially generous to specialists in psychiatry, endocrinology/diabetes/metabolism, internal medicine, and neurology. Companies increasingly used loopholes in the law to avoid public scrutiny. Conclusions. Disclosure laws are an important first step in bringing greater transparency to physician,industry relationships. But flaws and weaknesses limit the states' ability to render physician,industry exchanges fully transparent. Future efforts should build on these lessons to render physician,industry relationships fully transparent. [source] Perspectives on the 21st century development of functional foods: bridging Chinese medicated diet and functional foodsINTERNATIONAL JOURNAL OF FOOD SCIENCE & TECHNOLOGY, Issue 3 2001Yue Xu Functional foods, also known as nutraceuticals, medical foods or nutritional foods, are driving food markets around the world and are expected to be one of the emerging trends for the food industry in the new millennium. The concept of functional foods is rooted in a tradition, particularly in Asia, where people have always believed that a balanced diet and some herbal foods are therapeutic. However, while extensive studies in biochemistry and immunology, as well as clinical trials, have been conducted on selected functional foods or ingredients, the scientific features of most traditional herbals remain almost unknown. However, the fastest growing food market in the United States is that of herbal-based nutraceuticals such as ginseng, garlic and medical mushrooms. This review describes different aspects of functional foods and the Chinese medicated diet on the basis of current knowledge, discusses the building blocks for the science of functional foods and proposes a possible way to fuse a Chinese medicated diet into functional foods. [source] Nursing Diagnosis: Is It Time for a New Definition?INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 1 2008T. Heather Herdman PhD PURPOSE. The Diagnosis Development Committee (DDC) of NANDA International frequently receives proposed "physiologic" and "surveillance diagnosis" submissions that may not meet the current definition of nursing diagnosis (NANDA, 2007, p. 332). There has been a request for a vote on newly proposed definitions of nursing diagnosis, risk diagnosis, and syndromes. The purpose of this article is to provide information which enables members and interested nurses to continue the dialogue and to share their thoughts and also to consider the thoughts and information generated by the participants in the NANDA-I interest survey on the definition of nursing diagnoses. DATA SOURCES. An electronic survey of the current NANDA-I definitions, and potential changes to those definitions, was distributed via the NANDA-I Web site. This article summarizes the overall findings of that survey and provides an overview of commentary received from the 269 participants. CONCLUSIONS. It is necessary to continue the dialogue on this important decision and to provide a mechanism for input from members and interested nurses before reaching any conclusions on this subject. NURSING IMPLICATIONS. NANDA-I has been recognized as the leader in the development and implementation of nursing diagnoses and must act responsibly in assessing the changing and emerging trends in nursing practice and in responding to these trends. [source] Shifting Paradigms of Globalization: The Twenty-first Century Transition Towards Generics in Skilled Migration from IndiaINTERNATIONAL MIGRATION, Issue 5 2001Binod Khadria Globalization of human capital through international migration is no longer about global physical presence only; it is also about global applicability of skills across various fields of specialization. This marks the main characteristics of skilled migration from India to developed countries in the twenty-first century. The focus is shifting away from professionals in specific occupations, like doctors, engineers, scientists, architects, bankers, to information technology (IT) professionals embodying, in a way, more generic skills. In other words, it is the generic applicability of information and communications technology (ICT) which has led to large-scale migration of Indians skilled in IT. Moreover, the exodus comprises not only the fully trained and educated workers going abroad for employment, but also students - the semi-finished human capital - pursuing higher education in onshore as well as offshore universities of the developed countries. The new emigration is directed towards traditional host countries in the West such as the UK, Canada, and the US, but also towards newly emerging destinations in continental Europe (Germany, France, Belgium, Italy, Denmark), Australasia (Australia, New Zealand), East Asia (Japan, Republic of Korea), and South-East Asia (Singapore, Malaysia). By using mainly current information and informal data as reported in the media, this article perceives emerging trends and changes in the context of the global labour market for skills, and suggests a possible framework towards evolving strategies of remedial development. [source] Lobbying in the 21st centuryJOURNAL OF PUBLIC AFFAIRS, Issue 1 2003Lobbying in 2010 Abstract This paper suggests that the nature of activism is changing to take account of the shifts in political and economic conditions. It further goes on to consider that as a result of these emerging trends we have witnessed a generational shift in how governments, businesses, interest groups and citizens will interact. It is possible to place the issues and questions that this new environment raises under a number of broad headings,Democracy and Dissent, Government and Parliament, Media, and Lobbying ,each of which the paper deals with in turn.

[source] Cysteinyl-leukotrienes and their receptors in asthma and other inflammatory diseases: Critical update and emerging trendsMEDICINAL RESEARCH REVIEWS, Issue 4 2007Valérie Capra Abstract Cysteinyl-leukotrienes (cysteinyl-LTs), that is, LTC4, LTD4, and LTE4, trigger contractile and inflammatory responses through the specific interaction with G protein-coupled receptors (GPCRs) belonging to the purine receptor cluster of the rhodopsin family, and identified as CysLT receptors (CysLTRs). Cysteinyl-LTs have a clear role in pathophysiological conditions such as asthma and allergic rhinitis (AR), and have been implicated in other inflammatory conditions including cardiovascular diseases, cancer, atopic dermatitis, and urticaria. Molecular cloning of human CysLT1R and CysLT2R subtypes has confirmed most of the previous pharmacological characterization and identified distinct expression patterns only partially overlapping. Interestingly, recent data provide evidence for the immunomodulation of CysLTR expression, the existence of additional receptor subtypes, and of an intracellular pool of CysLTRs that may have roles different from those of plasma membrane receptors. Furthermore, genetic variants have been identified for the CysLTRs that may interact to confer risk for atopy. Finally, a crosstalk between the cysteinyl-LT and the purine systems is being delineated. This review will summarize and attempt to integrate recent data derived from studies on the molecular pharmacology and pharmacogenetics of CysLTRs, and will consider the therapeutic opportunities arising from the new roles suggested for cysteinyl-LTs and their receptors. © 2006 Wiley Periodicals, Inc.

Redgwell Abstract The continued emphasis on the importance of dietary fibers to the Western diet and the need for products with a lower calorific content is pressuring food companies to allocate more resources to the development of fiber-enriched products. The challenge to the industry is to accomplish this goal without sacrificing the organoleptic appeal of some of their core offerings. As future research details specific nutritional benefits of individual components of dietary fiber, food companies will need flexible alternatives in order to validate new ,functional' food claims and to respond rapidly to emerging trends in fiber-enriched products. These objectives will be achieved by understanding the physicochemical basis for the biotechnical functionality of fibers and by developing, and making available fibers which provide a broad spectrum of bioactive and texture modulating properties. [source] Mining and sustainable development: considerations for minerals supplyNATURAL RESOURCES FORUM, Issue 4 2001Ian B. Lambert Abstract Sustainable development involves meeting the needs of human societies while maintaining viable biological and physical Earth systems. The needs include minerals: metals, fuels, industrial and construction materials. There will continue to be considerable demand for virgin mineral resources, even if levels of recycling and efficiency of use are optimal, and rates of population growth and globalisation decrease significantly. This article aims to stimulate debate on strategic issues for minerals supply. While the world has considerable stocks of mineral resources overall, international considerations of the environmental and social aspects of sustainable development are beginning to result in limitations on where mining will be conducted and what types of deposits will be mined. Current and emerging trends favour large mines in parts of the world where mining can be conducted within acceptable limits of environmental and social impact. Finding new deposits that meet such criteria will be all the more challenging given a disturbing global decline in the rate of discovery of major economic resources over the last decade, and the decreasing land area available for exploration and mining. To attract responsible exploration and mining, governments of mining nations will need to provide: regional-scale geo-scientific datasets as required to attract and guide future generations of exploration; resource access through multiple and sequential land use regimes, and frameworks for dealing with indigenous peoples' issues; and arrangements for consideration of mining proposals and regulation of mines that ensure responsible management of environmental and social issues. The minerals industry will need to continue to pursue advances in technologies for exploration, mining, processing, waste management and rehabilitation, and in public reporting of environmental and social performance. [source] Information behavior in developing countries: Research, issues, and emerging trendsPROCEEDINGS OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE & TECHNOLOGY (ELECTRONIC), Issue 1 2007Dania Bilal Moderator The field of library and information science (LIS) has historically been a leading discipline in studying human information behavior (Spink & Cole, 2006). Information seeking in industrialized nations is grounded in theories and moving towards new directions and evolutionary approaches that often challenge the established paradigms of information behavior studies (see Case, 2007; Spink & Cole, 2006; Fisher, Erdelez, & Mckechnie, 2005; Chelton & Cool, 2004. Information behavior has been conceptualized in a holistic context that draws upon theories from various disciplines such as cognitive science, communication, psychology, and computer science (Nahl & Bilal, 2007; Spink & Cole, 2006). Compared to industrialized nations, most developing countries relegate towards the bottom heap of research on information behavior (Coleman, 2005; Britz, 2005). A panel of researchers, educators, and consultants will address research in information behavior in various contexts in developing countries, particularly in India, South Africa, and the Arab world. Based on their research findings and experiences, the speakers will trace themes, map the intellectual terrain, identify emerging trends and approaches, and frame issues related to information behavior research in these countries. Moreover, they will identify significant knowledge domains, concepts, and topics of application in information behavior research where there can be mutual exchange between developing countries and the industrialized nations (including the United States) to nurture and further growth in this area of study. [source] The analysis of the homoerotic and the pursuit of meaningTHE JOURNAL OF ANALYTICAL PSYCHOLOGY, Issue 3 2006Barry Miller Abstract:, This paper explores the dynamic tension between an evolving collective phenomenon and the nature of analytic process. Specifically, the focus will be erotic experiences which acquire a meaning through the culture at large, a meaning that may not be supportable when that material is subjected to psychological analysis. This stimulates a conflict between the symbolic attitude and the cultural perspective of the time. While the struggle between the individual and collective consciousness always emerges in analysis, the subject of same-gender sexual relations has become such a controversial and divisive issue in the current political environment that views toward homosexuality demand powerful allegiances and identification with either historic or contemporary ideas. People now identify as ,gay' and tend to see themselves as something akin to a race or perhaps alternative gender. Sexuality and relationship between same gendered people tends to be viewed through the lens of civil rights and the undeniable need for social equality. In this far-reaching and expanding collective phenomenon, psychology, in its support of human rights and accommodation to emerging trends, may be diminished in its capacity to pursue the meaning inherent in these human experiences. The position developed in this paper is that psychological experience, whether in the imaginal realm, dreams or personal consciousness, must be available for full analysis. Clinical experience and dreams are used to amplify this challenge to dynamic analytic practice. [source] The plot thickens: Land administration and policy in post-New Order IndonesiaASIA PACIFIC VIEWPOINT, Issue 1 2004Craig C. Thorburn Land reform is one of many agendas that have preoccupied policy makers, scholars and activists as the nation attempts to reinvent itself in the wake of the collapse of the 32-year New Order government of ex-President Suharto. This article examines some of the main debates swirling around the issue of land management and policy during the post-Suharto ,reformasi' period, and provides illustrations of current problems and emerging trends. The article begins with a brief overview of land law and policy in Indonesia, followed by a discussion of its philosophical and ideological basis. This is followed by a discussion of government reform during the New Order period and beyond, and the social and environmental costs of Indonesia's development. The discussion then turns to efforts to decentralise government, and implications on land admin-istration and policy. Case study examples are provided to illustrate the complex dynamic unfolding across the country.
