Selected AbstractsFRONTIER EFFICIENCY MEASUREMENT IN DEPOSIT-TAKING FINANCIAL MUTUALS: A REVIEW OF TECHNIQUES, APPLICATIONS, AND FUTURE RESEARCH DIRECTIONSANNALS OF PUBLIC AND COOPERATIVE ECONOMICS, Issue 1 2010Andrew C. Worthington ABSTRACT,:,Despite the global importance of mutuals in financial services, and the universal need to measure and improve organizational efficiency in all deposit-taking institutions, it is only relatively recently that the most advanced econometric and mathematical programming frontier techniques have been applied. This paper provides a synoptic survey of the comparatively few empirical analyses of frontier efficiency measurement in deposit-taking financial mutuals, comprising savings and loans, building societies and credit unions in Australia, the UK, and the USA. Both estimation and measurement techniques and the determinants of efficiency are examined. Particular focus is placed on how the results of these studies may help inform regulatory policy and managerial behaviour. [source] Acamprosate: Recent Findings and Future Research DirectionsALCOHOLISM, Issue 7 2008Karl Mann This article explores the mechanisms of action and the potential responder profile of acamprosate, a compound efficacious in relapse prevention of alcoholism. New evidence at the molecular and cellular level suggests that acamprosate attenuates hyper-glutamatergic states that occur during early abstinence and involves iono (NMDA)- and metabotrotropic (mGluR5) glutamate receptors along with augmented intracellular calcium release and electrophysiological changes. Thus mutant mice with enhanced glutamate levels exhibit higher alcohol consumption than wild type mice and respond better to acamprosate, demonstrating that acamprosate acts mainly on a hyper-glutamatergic system. This mode of action further suggests that acamprosate exhibits neuroprotective properties. In rats, cue-induced reinstatement behavior is significantly reduced by acamprosate treatment whereas cue-induced craving responses in alcohol-dependent patients seem not to be affected by this treatment. An ongoing study ("Project Predict") defines specific responder profiles for an individualized use of acamprosate and naltrexone. Neurophysiological as well as psychometric data are used to define 2 groups of patients: "reward cravers" and "relief cravers". While naltrexone should work better in the first group, acamprosate is hypothesized to be efficacious in the latter where withdrawal associated and/or cue induced hyper-glutamatergic states are thought to trigger relapse. Further research should target the definition of subgroups applying endophenotypic approaches, e.g. by detecting a hyperglutamatergic syndrome using MR spectroscopy. [source] The neurobiological profile of girls with ADHDDEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 4 2008E. Mark Mahone Abstract Since boys are more commonly diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) than girls, the majority of theories and published research studies of ADHD have been based on samples comprised primarily (or exclusively) of boys. While psychosocial impairment in girls with ADHD is well established, the neuropsychological and neurobiological basis of these deficits is less consistently observed. There is growing evidence that boys' and girls' brains develop and mature at different rates, suggesting that the trajectory of early anomalous brain development in ADHD may also be sex-specific. It remains unclear, however, whether earlier brain maturation observed in girls with ADHD is protective. In this review, we outline the current theory and research findings that seek to establish a unique neurobiological profile of girls with ADHD, highlighting sex differences in typical brain development and among children with ADHD. The review highlights findings from neurological, neurocognitive, and behavioral studies. Future research directions are suggested, including the need for longitudinal neuroimaging and neurobehavioral investigation beginning as early as the preschool years, and continuing through adolescence and adulthood, with consideration of identified sex differences in the development of ADHD. © 2008 Wiley-Liss, Inc.

Few Abstract: Very little research has examined the experiences of Black and White rural battered women. In this exploratory study of 88 participants, 30 rural battered women who sought assistance from domestic violence shelters in southwest Virginia were interviewed. Black and White rural women's experiences in the shelters, helpseeking, and perceived social support during and after their stay in the shelter were compared. Future research directions and suggestions to improve services are presented. [source] Effectiveness of maternity support belts in reducing low back pain during pregnancy: a reviewJOURNAL OF CLINICAL NURSING, Issue 11 2009Simone SM Ho Aims., This article aims to review the literature published to date on the types, current use, the biomechanical effects and adverse effects of maternity support belts for low back pain during pregnancy, to identify future research directions. Background., Lumbar/pelvic support belts are frequently recommended for the prevention and treatment of low back pain during pregnancy. Design., Systematic review. Methods., MEDLINE, CINAHL, the Cochrane Library and patents databases were electronically searched. Results., Maternity support belts belong to one of the four main types of maternity support garments, which are widely commercially-available. Current research showed limited evidence in support of the commercial maternity products regarding the effectiveness in the prevention and/or treatment of low back pain during pregnancy, other than that from the manufacturers. However, potential stabilisation effect of maternity support belt was demonstrated in some studies. Adverse effects reported include increased pain, fetal heart rate changes, skin irritation and discomfort. Conclusions., There is insufficient scientific evidence to conclude that wearing maternity support belts reduces pregnancy-related low back pain and/or pelvic girdle pain. Future research directions in the area of biomechanics and physiology are recommended. Relevance to clinical practice., This review provides comprehensive understanding of the effectiveness of maternity support belts for the relief of low back pain during pregnancy which will facilitate healthcare professionals in providing evidence-based advice to their patients. [source] In Search of a Competition Policy in a Competitive Economy: The Case of Hong KongJOURNAL OF CONSUMER AFFAIRS, Issue 1 2003SUK-CHING HO The authors propose an exploratory framework to study competition policy development in general and apply it in the context of Hong Kong. Competition policy (in the U.S., commonly referred to as antitrust policy) is defined here as concerned with the public policy prohibiting anticompetitive behavior and the abuse of dominant market power on the part of businesses. The framework identifies four core variables that are important in influencing the development and implementation of a competition policy. These variables are the consumer protection agenda, external pressure, the political landscape, and the size of the economy. It is proposed that the way government responded to these forces has been instrumental in shaping how and why the competition policy debate in Hong Kong evolved the way it did. It also underscores the importance of recognizing the indigenous nature in the development of competition policy in any economy. Future research directions to generalize the framework are also suggested. These include further development and expansion of the core variables, contextualization of the framework for cross-national comparisons, and undertaking longitudinal studies to examine the sensitivities of the competition policy to changes in the core forces over time. [source] IMPACT OF MARITAL AND PSYCHOLOGICAL DISTRESS ON THERAPEUTIC ALLIANCE IN COUPLES UNDERGOING COUPLE THERAPYJOURNAL OF MARITAL AND FAMILY THERAPY, Issue 2 2005Salima Mamodhoussen In this study, we describe the psychometric properties of the Couple Therapy Alliance Scale, revised (CTAS,r) and investigates the impact of marital and psychiatric distress on alliance. Seventy-nine couples in therapy completed a French version of the Dyadic Adjustment Scale and of the Psychiatric Symptoms Index at session one, and a French version of the CTAS,r at session three. Results indicate that the French version of the CTAS,r has adequate psychometric properties, although the subscales of the instrument are highly intercorrelated. Furthermore, marital adjustment predicts alliance scores, whereas psychiatric symptoms do not. Finally, male marital adjustment and female psychiatric symptoms are lower in couples where spouses have divergent perceptions of the alliance. Future research directions are discussed. [source] Selenium and selenoproteins in the brain and brain diseasesJOURNAL OF NEUROCHEMISTRY, Issue 1 2003Jun Chen Abstract Over the past three decades, selenium has been intensively investigated as an antioxidant trace element. It is widely distributed throughout the body, but is particularly well maintained in the brain, even upon prolonged dietary selenium deficiency. Changes in selenium concentration in blood and brain have been reported in Alzheimer's disease and brain tumors. The functions of selenium are believed to be carried out by selenoproteins, in which selenium is specifically incorporated as the amino acid, selenocysteine. Several selenoproteins are expressed in brain, but many questions remain about their roles in neuronal function. Glutathione peroxidase has been localized in glial cells, and its expression is increased surrounding the damaged area in Parkinson's disease and occlusive cerebrovascular disease, consistent with its protective role against oxidative damage. Selenoprotein P has been reported to possess antioxidant activities and the ability to promote neuronal cell survival. Recent studies in cell culture and gene knockout models support a function for selenoprotein P in delivery of selenium to the brain. mRNAs for other selenoproteins, including selenoprotein W, thioredoxin reductases, 15-kDa selenoprotein and type 2 iodothyronine deiodinase, are also detected in the brain. Future research directions will surely unravel the important functions of this class of proteins in the brain. [source] Determining factors of academic library Web site usageJOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, Issue 14 2007John H. Heinrichs This study develops three alternative models of academic library Web site usage based on the Technology Acceptance Model (TAM). The three alternative models depict relationships among various intrinsic and extrinsic determinant factors of an academic library's Web site usage. The four factors included in the models are perceived ease-of-use, perceived usefulness, service functionality, and task functionality. These four factors are hypothesized to affect directly or indirectly both factors of satisfaction and intention-to-use. LISREL analysis using survey data shows that the best-fit model is the "Dual Mediation Impact" Model. Research and managerial implications for the academic library are discussed. Future research directions and limitations also are provided.

[source] Molecular methods for arthropod bloodmeal identification and applications to ecological and vector-borne disease studiesMOLECULAR ECOLOGY RESOURCES, Issue 1 2009REBEKAH J. KENT Abstract DNA-based methods have greatly enhanced the sensitivity and specificity of hematophagous arthropod bloodmeal identification. A variety of methods have been applied to study the blood-feeding behaviour of mosquitoes, ticks, black flies and other blood-feeding arthropods as it relates to host,parasite interactions and pathogen transmission. Overviews of the molecular techniques used for bloodmeal identification, their advantages, disadvantages and applications are presented for DNA sequencing, group-specific polymerase chain reaction primers, restriction fragment length polymorphism, real-time polymerase chain reaction, heteroduplex analysis, reverse line-blot hybridization and DNA profiling. Technical challenges to bloodmeal identification including digestion and analysis of mixed bloodmeals are discussed. Analysis of bloodmeal identification results remains a challenge to the field, particularly with regard to incorporation of vertebrate census and ecology data. Future research directions for molecular analysis of arthropod bloodmeals are proposed. [source] The ultrastructure of chilling stressPLANT CELL & ENVIRONMENT, Issue 4 2000H. A. Kratsch ABSTRACT Chilling injury to crop plants was first described 70 years ago and has been systematically investigated with electron microscopy since the late 1960s. Chloroplasts are the first and most severely impacted organelle. Thylakoids swell and distort, starch granules disappear, and a peripheral reticulum (vesicles arising from inner membrane of chloroplast envelope) appears. Chloroplast disintegration follows prolonged chilling. Mitochondria, nuclei and other organelles are less susceptible to chilling injury. Organellar development and ontogeny may also be disrupted. The inherent chilling sensitivity of a plant, as well as the ability of some species to acclimate to chilling, influence the timing and appearance of ultrastructural injury with the resulting outcome being mild, moderate, or severe. Other environmental factors that exacerbate injury are irradiance, chilling duration, and water status. The physiological basis for chloroplast swelling may be linked to chilling-stable starch-degrading enzymes that produce soluble sugars thus lowering stromal water potential at a time when chloroplast photosynthate export is reduced. Thylakoid dilation appears to be related to photo-oxidative conditions produced during chilling in the light. The peripheral reticulum is proposed to increase surface area of the transport-limiting membrane (chloroplast inner membrane) in response to the chilling-induced reduction in metabolite transport. Many of the ultrastructural symptoms appearing during moderate stress resemble those seen in programmed cell death. Future research directions are discussed. [source] Impact of customer preconsumption mood on the evaluation of employee behavior in service encountersPSYCHOLOGY & MARKETING, Issue 10 2002Veronica Liljander The influence of customers' affective states on the evaluation of service encounters has been conceptually discussed for more than a decade. However, empirical studies, field studies in particular, are scarce. Recent studies have contributed to the area by empirically demonstrating mood effects on service satisfaction. Because of the interpersonal nature of services, the behavior of the service personnel is of utmost importance for overall service satisfaction. This article extends previous research by investigating the impact of customers' reported preconsumption mood on the evaluation of three service behaviors, proposed by Winsted (2000) in her seminal study. The findings support the existence of three service behavioral dimensions, namely, concern, congeniality and uncivility, and show that mood valence influences these behaviors as well as encounter satisfaction. Furthermore, the study demonstrates the importance of past service experiences for customers' responses, especially their repurchase intentions. Future research directions regarding mood effects in services are also discussed. © 2002 Wiley Periodicals, Inc. [source] The Stress-Buffering Effects of Control on Task Satisfaction and Perceived Goal Attainment: An Experimental Study of the Moderating Influence of Desire for ControlAPPLIED PSYCHOLOGY, Issue 4 2009Stacey L. Parker The purpose of the present study was to examine the extent to which Desire for Control (DFC) interacts with experimental manipulations of demand and control, and the consequences of these interactions on task satisfaction and perceived goal attainment (i.e. task performance and task mastery). It was expected that the proposed stress-buffering effects of control would be evident only for individuals high in DFC. Moreover, it was anticipated that control may have a stress-exacerbating effect for those low in DFC. These hypotheses were tested on a sample of 137 first year psychology students who participated in an in-basket activity under low and high conditions of demand and control. Results revealed that the proposed stress-buffering effect of control was found only for those high in DFC and a stress-exacerbating effect of increased control was evident for those low in DFC on task performance and task mastery perceptions. Future research directions and the implications of these findings to applied settings are discussed. Cette recherche avait pour objet de voir dans quelle mesure le besoin de maîtriser la situation (DFC) interagit avec des manipulations expérimentales portant sur les exigences et le contrôle, ainsi que d'observer les conséquences de ces interactions sur la satisfaction liée à la tâche et à la réussite perçue (relative à la performance et à la maîtrise de la tâche). On a fait l'hypothèse que seuls les individus présentant un haut niveau de DFC verraient leur stress atténué par la possibilité de maîtriser la situation. En outre, on pensait que la maîtrise de la situation pouvait accroître le stress de ceux ayant un faible niveau de DFC. Ces hypothèses ont été mises à l'épreuve sur un échantillon de 137 étudiants de première année de psychologie qui subirent un in-basket test dans des conditions de haut et de bas niveaux d'exigence et de contrôle. Les résultats montrent que l'atténuation du stress par la maîtrise de la situation n'existe que pour les hauts niveaux de DFC, alors qu'une maîtrise accrue stimule le stress chez les bas niveaux, aussi bien sur la perception de la performance que sur celle de la domination de la tâche. On propose des orientations pour de futures recherches et l'on réfléchit aux retombées de ces résultats sur la vie pratique. [source] Child sexual abuse and HIV transmission in sub-Saharan AfricaCHILD ABUSE REVIEW, Issue 2 2008Kevin Lalor Abstract The purpose of this paper is to examine the risks of HIV transmission to children through sexual abuse and exploitation in sub-Saharan Africa. The paper is based on a review of pertinent literature. Child sexual abuse in this region must be defined broadly enough to encompass widespread coercion or violence in early sexual relations in some regions, the practice of ,transactional sex' and constructions of masculinity, emphasising multiple sexual partners and power over women and girls. The high HIV prevalence in sub-Saharan Africa is briefly described. Research evidence showing the link between child sexual abuse and HIV transmission is reviewed, although this is a topic where very little direct empirical work has been conducted. Particular methodological and ethical difficulties have been encountered by researchers. Future research directions are indicated. Copyright © 2008 John Wiley & Sons, Ltd. [source] Pruritus measurement and treatmentCLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 3 2009M. D. Langner Summary Pruritus measurement is problematic, because of its subjective nature and poor localization. Ratio scales enhance the usefulness of the visual analogue scale (VAS) by reducing variation; other scales such as the generalized labelled magnitude scale may also be useful. Pruritus neuroanatomy includes peripheral receptors, peripheral and central nerves, ascending and descending spinal pathways, and several brain regions. Pruritus receptors include Merkel discs and free nerve endings, and itch receptors have fast or slow adaptation. In this review, we discuss the pathophysiology of pruritus in atopic dermatitis, psoriasis and scabies. Pruritus treatment is reviewed for topical agents and antihistamines. Future research directions are suggested. [source] The development of 3-D visualization technology: the potential impact on interior design and its consumersINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 5 2009Seunghae Lee Abstract Three-dimensional visualization has developed and improved significantly over the last several decades and resulted in consumers' having multidimensional, multi-sensory experiences with a wide range of products and services. It has affected the built environment and its related businesses. Designers create 3-D images and walk-through animations to communicate with their clients more clearly, starting from the early stage of the design process. The interior,design-related material manufacturers and retailers have enhanced their online stores with 3-D visualization features to improve their interactivity and provide user-friendly interfaces for product information search and purchase planning. Because of the continuing widespread interest in 3-D visualization and the amount of its applications in the interior design field, a review of this area was a necessity to suggest the future research direction for the development of 3-D visualization in interior design. This paper sought to demonstrate the status of the development of 3-D visualization and its impact on the interior design field and its consumers while highlighting an area where future research is a potentially considerable benefit in developing 3-D visualization in interior design. [source] Managing very large distributed data sets on a data gridCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 11 2010Miguel Branco Abstract In this work we address the management of very large data sets, which need to be stored and processed across many computing sites. The motivation for our work is the ATLAS experiment for the Large Hadron Collider (LHC), where the authors have been involved in the development of the data management middleware. This middleware, called DQ2, has been used for the last several years by the ATLAS experiment for shipping petabytes of data to research centres and universities worldwide. We describe our experience in developing and deploying DQ2 on the Worldwide LHC computing Grid, a production Grid infrastructure formed of hundreds of computing sites. From this operational experience, we have identified an important degree of uncertainty that underlies the behaviour of large Grid infrastructures. This uncertainty is subjected to a detailed analysis, leading us to present novel modelling and simulation techniques for Data Grids. In addition, we discuss what we perceive as practical limits to the development of data distribution algorithms for Data Grids given the underlying infrastructure uncertainty, and propose future research directions.

[source] PUBLIC PREFERENCES FOR REHABILITATION VERSUS INCARCERATION OF JUVENILE OFFENDERS: EVIDENCE FROM A CONTINGENT VALUATION SURVEY,CRIMINOLOGY AND PUBLIC POLICY, Issue 4 2006DANIEL S. NAGIN Research Summary: Accurately gauging the public's support for alternative responses to juvenile offending is important, because policy makers often justify expenditures for punitive juvenile justice reforms on the basis of popular demand for tougher policies. In this study, we assess public support for both punitively and nonpunitively oriented juvenile justice policies by measuring respondents' willingness to pay for various policy proposals. We employ a methodology known as "contingent valuation" (CV) that permits the comparison of respondents' willingness to pay (WTP) for competing policy alternatives. Specifically, we compare CV-based estimates for the public's WTP for two distinctively different responses to serious juvenile crime: incarceration and rehabilitation. An additional focus of our analysis is an examination of the public's WTP for an early childhood prevention program. The analysis indicates that the public is at least as willing to pay for rehabilitation as punishment for juvenile offenders and that WTP for early childhood prevention is also substantial. Implications and future research directions are outlined. Policy Implications: The findings suggest that lawmakers should more actively consider policies grounded in rehabilitation, and, perhaps, be slower to advocate for punitive reforms in response to public concern over high-profile juvenile crimes. Additionally, our willingness to pay findings offer encouragement to lawmakers who are uncomfortable with the recent trend toward punitive juvenile justice policies and would like to initiate more moderate reforms. Such lawmakers may be reassured that the public response to such initiatives will not be hostile. Just as importantly, reforms that emphasize leniency and rehabilitation can be justified economically as welfare-enhancing expenditures of public funds. The evidence that the public values rehabilitation more than increased incarceration should be important information to cost-conscious legislators considering how to allocate public funds. Cost-conscious legislatures may become disenchanted with punitive juvenile justice policies on economic grounds and pursue policies that place greater emphasis on rehabilitation. They may be reassured, on the basis of our findings, that the public will support this move. [source] The Attentional Resource Allocation Scale (ARAS): psychometric properties of a composite measure for dissociation and absorption,DEPRESSION AND ANXIETY, Issue 8 2010R. N. Carleton M.A. Abstract Background: Differences in attentional processes have been linked to the development and maintenance of psychopathology. Shifts in such processes have been described by the constructs Dissociation and Absorption. Dissociation occurs when external and/or internal stimuli are excluded from consciousness due to discrepant, rather than unitary, manifestations of cognitive awareness [Erdelyi MH. 1994: Int J Clin Exp Hypnosis 42:379,390]. In contrast, absorption can be conceptualized by a focus on limited stimuli, to the exclusion of other stimuli, because of unifying, rather than discrepant, manifestations of cognitive awareness. The Dissociative Experiences Scale [DES; Bernstein EM, Putnam FW. 1986: J Nerv Ment Dis 174:727,735] and Tellegen Absorption Scale [TAS; Tellegen A, Atkinson G. 1974: J Abnorm Psychol 83:268,277] are common measures of each construct; however, no factor analyses are available for the TAS and despite accepted overlap, no one has assessed the DES and TAS items simultaneously. Previous research suggests the constructs and factor structures need clarification, possibly including more parsimonious item inclusion [Lyons LC, Crawford HJ. 1997: Person Individ Diff 23:1071,1084]. The purpose of this study was to evaluate the factor structure of the DES and TAS and create a psychometrically stable measure of Dissociation and Absorption. Methods: This study included data from an undergraduate (n=841; 76% women) and a community sample (n=233; 86% women) who each completed the DES and TAS. Results: Exploratory factor analyses [Osborne JW (ed). 2008: Best Practices in Quantitative Methods. Los Angeles: Sage Publications Inc.] with all DES and TAS items suggested a 15-item 3-factor solution (i.e., imaginative involvement, dissociative amnesia, attentional dissociation). Confirmatory factor analyses resulted in excellent fit indices for the same solution. Conclusions: The items and factors were conceptualized in line with precedent research as the Attentional Resource Allocation Scale (ARAS). Comprehensive results, implications, and future research directions are discussed. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [source] Factorial validity of the Childhood Trauma Questionnaire in men and womenDEPRESSION AND ANXIETY, Issue 4 2001Kristi D. Wright B.A. Abstract In an effort to confirm the factorial validity of the Childhood Trauma Questionnaire (CTQ) across sex, the items from the CTQ for 916 university students were subjected to confirmatory factor analysis. Results indicated that the factor structure for the CTQ was significantly different for men and women. For women, the items from the Physical Abuse subscale did not create a stable factor and thus appear not to be conceptually valid. Conversely, for men, the five-factor model provided a relatively good fit to the data. This investigation provides important information regarding sex differences in the factorial validity of the CTQ. Implications and future research directions are discussed.

Gibson Ecology Letters (2010) 13: 223,234 Abstract Endosymbiosis is a pervasive, powerful force in arthropod evolution. In the recent literature, bacterial symbionts of insects have been shown to function as reproductive manipulators, nutritional mutualists and as defenders of their hosts. Fungi, like bacteria, are also frequently associated with insects. Initial estimates suggest that insect,fungal endosymbionts are hyperdiverse, yet there has been comparatively little research investigating the roles that fungi play in their insect hosts. In many systems in which the bacterial symbionts are well-characterized, the possible presence of fungi has been routinely ignored. Why has there been so little research on this important group of symbionts? Here, we explore the differences between fungal and bacterial endosymbiotic insect mutualists. We make predictions about why a bacterium or fungus might be found associated with an insect host given particular ecological, physiological, or evolutionary conditions. We also touch on the various hurdles for studying fungal vs. bacterial endosymbionts and potential future research directions. [source] Forgiveness in Marriage: Current Status and Future DirectionsFAMILY RELATIONS, Issue 4 2006Frank D.

Forgiveness appears to be especially important in the marital relationship. This article offers an overview of forgiveness in marriage including a review of major research and clinical efforts in this area. A number of recommendations are offered for practitioners and future research directions are outlined. Marital forgiveness is seen as an exciting area for future exploration and one that is ripe with possibility. [source] Potential changes in skipjack tuna (Katsuwonus pelamis) habitat from a global warming scenario: modelling approach and preliminary resultsFISHERIES OCEANOGRAPHY, Issue 4-5 2003Harilaos Loukos Abstract Recent studies suggest a reduction of primary production in the tropical oceans because of changes in oceanic circulation under global warming conditions caused by increasing atmospheric CO2 concentration. This might affect the productivity of medium and higher trophic levels with potential consequences on marine resources such as tropical tuna. Here we combine the projections of up-to-date climate and ocean biogeochemical models with recent concepts of representation of fish habitat based on prey abundance and ambient temperature to gain some insight into the impact of climate change on skipjack tuna (Katsuwonus pelamis), the species that dominates present-day tuna catch. For a world with doubled atmospheric CO2 concentration, our results suggest significant large-scale changes of skipjack habitat in the equatorial Pacific. East of the date line, conditions could be improved by an extension of the present favourable habitat zones of the western equatorial Pacific, a feature reminiscent of warming conditions associated with El Niño events. Despite its simplicity and the associated underlying hypothesis, this first simulation is used to stress future research directions and key issues for modelling developments associated to global change.

Levine Abstract Dense transition metal borides have recently been identified as superhard materials that offer the possibility of ambient pressure synthesis compared to the conventional high pressure, high temperature approach. This feature article begins with a discussion of the relevant physical properties for this class of compounds, followed by a summary of the synthesis and properties of several transition metal borides. A strong emphasis is placed on correlating mechanical properties with electronic and atomic structure of these materials in an effort to better predict new superhard compounds. It concludes with a perspective of future research directions, highlighting some recent results and presenting several new ideas that remain to be tested. [source] SOCIAL CONSTRUCTION OF HYDROPOLITICS: THE GEOGRAPHICAL SCALES OF WATER AND SECURITY IN THE INDUS BASIN,GEOGRAPHICAL REVIEW, Issue 4 2007Daanish Mustafa ABSTRACT. The article identifies important themes and future research directions for analyzing water and conflict dynamics at the subnational scale in the Indus Basin. A historical overview of water development in the Indus Basin suggests that the water-security nexus was always a salient theme in the minds of water developers, even in the nineteenth century. Conflicts over contemporary large-scale water-development projects in the Indian and Pakistani parts of the Indus Basin are reviewed. Engineers' single-minded focus on megaprojects, to the neglect of the wider set of values that societies attach to water resources in the eastern and western Indus Basin are largely to blame for continuing low-grade conflict in the basin. A review of local-level conflicts over water supply and sanitation in Karachi and the distribution of irrigation water in Pakistani Punjab illustrates the critical role of governance and differential social power relations in accentuating conflict. The article argues against neo-Malthusian assumptions about the inevitability of conflict over water because of its future absolute scarcity. Instead, the article seeks to demonstrate that, despite evidence suggesting that international armed conflict over water does not exist, the potential for political instability over domestic water distribution and development issues is real. The question of whether conflict at the subnational scale will culminate in violence will depend on how water-resources institutions in the basin behave. [source] Chronic Headache and Potentially Modifiable Risk Factors: Screening and Behavioral Management of Sleep DisordersHEADACHE, Issue 1 2008Jeanetta C. Rains PhD Sleep-related variables have been identified among risk factors for frequent and severe headache conditions. It has been postulated that migraine, chronic daily headache, and perhaps other forms of chronic headache are progressive disorders. Thus, sleep and other modifiable risk factors may be clinical targets for prevention of headache progression or chronification. The present paper is part of the special series of papers entitled "Chronification of Headache" describing the empirical evidence, future research directions, proposed mechanisms, and risk factors implicated in headache chronification as well as several papers addressing individual risk factors (ie, sleep disorders, medication overuse, psychiatric disorders, stress, obesity). Understanding the link between risk factors and headache may yield novel preventative and therapeutic approaches in the management of headache. The present paper in the special series reviews epidemiological research as a means of quantifying the relationship between chronic headache and sleep disorders (sleep-disordered breathing, insomnia, circadian rhythm disorders, parasomnias) discusses screening for early detection and treatment of more severe and prevalent sleep disorders, and discusses fundamental sleep regulation strategies aimed at headache prevention for at-risk individuals. [source] Perceived fairness of web-based applicant screening procedures: Weighing the rules of justice and the role of individual differencesHUMAN RESOURCE MANAGEMENT, Issue 2-3 2004Brian R. Dineen Four previously established characteristics of procedural justice (consistency, opportunity to perform, reconsideration opportunity, and feedback timeliness) and one additional characteristic (automated versus human decision agent) were manipulated in a policy-capturing design to examine their relative importance in predicting fairness perceptions in a Web-based applicant-screening context. Results showed that all five justice characteristics influenced fairness perceptions and that a hierarchy of importance among the characteristics existed, with consistency weighted most heavily, followed by opportunity to perform. Gender, conscientiousness, and job application experience moderated the effects of several of these characteristics in predicting fairness perceptions. Implications and future research directions are discussed. © 2004 Wiley Periodicals, Inc.
