Terms modified by Extensive Literature Selected AbstractsDeterminants of Internet Financial Reporting by New Zealand CompaniesJOURNAL OF INTERNATIONAL FINANCIAL MANAGEMENT & ACCOUNTING, Issue 1 2003Peter Oyelere The development of the Internet as a global medium for the dissemination of corporate financial information creates a new reporting environment. Extensive literature examines the determinants of voluntary financial reporting through traditional media such as print,based annual reports. This paper extends this literature by examining the voluntary adoption of the Internet as a medium for transmitting financial reports and determinants of such voluntary practice by New Zealand companies. The results indicate that some determinants of traditional financial reporting,firm size, liquidity, industrial sector and spread of shareholding,are determinants of voluntary adoption of Internet financial reporting (IFR). However, other firm characteristics, such as leverage, profitability and internationalization do not explain the choice to use the Internet as a medium for corporate financial reporting. [source] EFNS guideline on diagnosis and management of limb girdle muscular dystrophiesEUROPEAN JOURNAL OF NEUROLOGY, Issue 12 2007F. Norwood The limb girdle muscular dystrophies (LGMD) are termed as such as they share the characteristic feature of muscle weakness predominantly affecting the shoulder and pelvic girdles; their classification has been completely revised in recent years because of elucidation of many of the underlying genetic and protein alterations in the various subtypes. An array of diagnostic measures is possible but with varying ease of use and availability. Several aspects of muscle cell function appear to be involved in the causation of muscle pathology. These cellular variations may confer some specific clinical features thus permitting recognition of the LGMD subtype and hence directing appropriate levels of monitoring and intervention. Despite an extensive literature on the individual limb girdle dystrophies, these publications may be impenetrable for the general neurologist in this increasingly complex field. The proposed guidelines suggest an approach to the diagnosis and monitoring of the limb girdle dystrophies in a manner accessible to general neurologists. [source] Induction of endogenous pathways by antiepileptics and clinical implicationsFUNDAMENTAL & CLINICAL PHARMACOLOGY, Issue 5 2005M. Strolin Benedetti Abstract The aim of this study was to review modifications of the endogenous pathways (e.g. enzyme elevations, normal body constituent depletion or higher formation/excretion of endogenous metabolites) which could be ascribed to enzyme induction by antiepileptic drugs (AEDs). Information on older (e.g. phenobarbital, phenytoin and carbamazepine) and newer drugs (where information is available) is discussed together with clinical implications. The enzymes involved in the endogenous pathways and induced by the AEDs will not be limited to the hepatic microsomal enzymes; extrahepatic enzymes and/or enzymes present in other subcellular fractions will also be discussed, if pertinent. The induction of endogenous pathways by AEDs has been taken into account in the past, but much less emphasis has been given compared with the extensive literature on induction by AEDs of the metabolism of concomitantly administered drugs, either of the same or of different classes. Not all of the endogenous pathways examined and induced by AEDs appear to result in serious clinical consequences (e.g. induction of hepatic ALP, increased excretion of d -glucaric acid or of 6, -hydroxycortisol). In some cases, induction of some pathways (e.g. increase of high-density lipoprotein cholesterol or of conjugated bilirubin) might even be a beneficial side-effect, however enzyme induction is considered rather a detrimental aspect for an AED, as induction is generally a broad and a non-specific phenomenon. The new AEDs have generally less induction potential than the older agents. Yet some (felbamate, topiramate, oxcarbazepine and lamotrigine) have the potential for inducing enzymes, whereas others (levetiracetam, gabapentin and vigabatrin) appear to be completely devoid of enzyme inducing characteristics, at least as far as the enzymes investigated are concerned. [source] Boundary Perturbation Methods for Water WavesGAMM - MITTEILUNGEN, Issue 1 2007David P. Nicholls Abstract The most successful equations for the modeling of ocean wave phenomena are the free,surface Euler equations. Their solutions accurately approximate a wide range of physical problems from open,ocean transport of pollutants, to the forces exerted upon oil platforms by rogue waves, to shoaling and breaking of waves in nearshore regions. These equations provide numerous challenges for theoreticians and practitioners alike as they couple the difficulties of a free boundary problem with the subtle balancing of nonlinearity and dispersion in the absence of dissipation. In this paper we give an overview of, what we term, "Boundary Perturbation" methods for the analysis and numerical simulation of this "water wave problem". Due to our own research interests this review is focused upon the numerical simulation of traveling water waves, however, the extensive literature on the initial value problem and additional theoretical developments are also briefly discussed.

KGaA, Weinheim) [source] Searching for Belonging , An Analytical FrameworkGEOGRAPHY COMPASS (ELECTRONIC), Issue 6 2010Marco Antonsich Belonging is a notion both vaguely defined and ill-theorized. Scholars in various social disciplines often take this notion for granted, as if its meaning is somewhat self-explanatory. Others tend to equate it with the notion of identity, citizenship, or both. By relying on a critical reading of an extensive literature across academic disciplines, this study aims to offer an analytical framework for the study of belonging. I argue that belonging should be analyzed both as a personal, intimate, feeling of being ,at home' in a place (place-belongingness) and as a discursive resource that constructs, claims, justifies, or resists forms of socio-spatial inclusion/exclusion (politics of belonging). The risk of focusing only on one of these two dimensions is to fall in the trap of either a socially de-contextualized individualism or an all-encompassing social(izing) discourse. The open question is whether the increasing cultural and ethnic diversification of contemporary societies can lead to the formation of communities of belonging beyond communities of identity. [source] Education for All: Reassessing the Historiography of Education in Colonial IndiaHISTORY COMPASS (ELECTRONIC), Issue 2 2009Catriona Ellis This essay won the 2007 History Compass Graduate Essay Prize, Asia Section. Despite the extensive literature on the history of education in colonial India, historians have confined their arguments to very narrow themes linked to colonial epistemological dominance and education as a means of control, resistance and dialogue. These tend to mirror the debates of the colonial period, particularly regarding the Anglicist-Orientalist controversy. This article argues that such an approach is both gendered and hierarchical, and seeks to fundamentally redress the balance. It looks firstly at formal school education , colonial and indigenous , in both philosophical and technological terms. It then turns to education as experienced by the majority of Indian children outwith the classroom, either formally or within the domestic sphere. The article then looks at the neglected recipients of education, and seeks to re-establish children as agents within these adult-driven agendas. By considering educational discourse and practice, and the emerging historiography of Indian childhood and children, we can begin to establish a more rounded and inclusive picture of what education really meant. [source] The trajectory of minor stroke recovery for men and their female spousal caregivers: literature reviewJOURNAL OF ADVANCED NURSING, Issue 6 2007Theresa L. Green Abstract Title.,The trajectory of minor stroke recovery for men and their female spousal caregivers: literature review Aim., This paper is a report of a narrative review to examine the current state of knowledge regarding the impact of minor stroke on male patients and their female spousal caregivers' recovery trajectory and quality of life. Background., Minor stroke survivors are often discharged early in the recovery process. The perception of the healthcare community that these patients and their female spousal caregivers will experience an uneventful recovery may lead to inadequate preparation for the postdischarge period. Methods., A range of databases was searched to identify papers addressing ,minor stroke', ,transitions', ,quality of life', ,chronic disease', ,caregivers' and ,spouse caregivers', including AARP Ageline, AMED, CINAHL, Evidence Based Medicine Reviews, MEDLINE and PsychInfo. Papers published in English from 1990 to December 2006 were included. Thirty-four papers were in the final data set. Results., Minor stroke survivors and their female spousal caregivers may experience major challenges in adaptations postdischarge. The trajectory of minor stroke recovery may necessitate a re-evaluation of life plans, rethinking of priorities and integration of resulting disabilities into current and emerging life situations for both stroke survivors and their female spousal caregivers. In many cases these adaptations are compounded by transitions associated with the normal ageing process. Conclusion., While there is extensive literature on stroke recovery and the role of caregivers in general, there is little available describing the recovery of minor stroke survivors in relation to the normal ageing process. Further research is needed examining recovery from a transitional perspective, to support nurses and other health professionals discharge planning. [source] Ecology, politics and policyJOURNAL OF APPLIED ECOLOGY, Issue 3 2007JOHN H. LAWTON Summary 1,The British Ecological Society aims to promote the science of ecology through research and to use the findings of such research to educate the public and influence policy decisions which involve ecological matters.' Yet, how successful have we been in influencing UK and EU environmental policy? 2Many scientists hold to the ,deficit model' of turning science into policy, the view that if only politicians are told what the science reveals, ,correct' policies will automatically follow. Nothing could be further from the truth. Politicians have all kinds of reasons, some valid, some less valid, not to adopt what often seem to us to be common sense policies to protect the environment. 3Here, I explore some of the successes and failures of ecologists to influence UK and European environmental policy, using acid deposition, the collapse of global marine fisheries, GM crops and climate change, carbon dioxide and ocean acidification as examples. I briefly review the extensive literature (largely ignored by natural scientists) on what social scientists have to say about evidence-based policy-making (or the lack of it) and why it often appears to be so difficult to persuade politicians to adopt sound environmental policies. 4Synthesis and applications. Ecologists can, and do, influence government policy on the environment, but often via complex and iterative interactions that can be painfully slow, and may require fundamental changes in politicians' belief systems, values and norms. [source] Social and Environmental Disclosure and Corporate Characteristics: A Research Note and ExtensionJOURNAL OF BUSINESS FINANCE & ACCOUNTING, Issue 3-4 2001Rob Gray This paper is concerned with the attempts to explain the disclosure of social and environmental information in the annual reports of large companies by reference to observable characteristics of those companies. An extensive literature has sought to establish whether variables such as corporate size, profit and industry segments can explain corporations' disclosure practices. The results from that predominantly North American and Australasian literature are largely inconclusive. This paper provides an extension of that literature by considering a more disaggregated specification of social and environmental disclosure and by employing a detailed time-series data set. By so doing, the paper tests two possible explanations for the inconclusiveness of prior research: namely that any relationships between corporate characteristics and disclosure are dependent upon the type of disclosure and that any such relationships are not stable through time. The results provide support for these explanations as sufficient, if not necessary, conditions for explaining the inconsistency in prior results. [source] The Monday effect in U.S. cotton pricesAGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 3 2009Stephen P. Keef There is an extensive literature on the Monday effect with stock indices. It is regularly reported that the return on Monday is correlated with the return on the prior Friday. The bad Monday effect occurs when the return on the preceding Friday is negative. Cotton is an economically important commodity in the United States and around the world. This investigation into the daily price seasonality in the U.S. cotton market is based on spot prices from Memphis and futures prices from the New York Cotton Exchange. The regression methodologies employ adjustments to control for undesirable properties in the error terms. There are three main conclusions. First, the close-to-close changes in the futures price and in the spot price exhibit a negative Monday effect. Second, a negative bad Monday effect is observed on Mondays using close-to-close prices. The effect is present during the weekend nontrading period and continues into trading on Mondays. Third, the negative bad Monday effect does not appear to weaken in close-to-close prices and during the weekend over the period examined (1987,2003). However, there is weak evidence of a temporal decline during trading on Mondays. [EconLit Citations: G12, G14, Q14]. © 2009 Wiley Periodicals, Inc. [source] The impact of exchange rate volatility on U.S. poultry exportsAGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 2 2006Titus O. Awokuse Existing empirical evidence on the effect of exchange rate uncertainty on trade is generally conflicting and inconclusive. While some studies found a positive relationship between exchange rate volatility and trade, others argue for the opposite. Furthermore, the vast majority of past studies only focused on aggregate trade flow data. The lack of extensive literature on studies based on disaggregated and commodity-level data may partially explain the ambiguity in past empirical evidence. This paper re-examines the relationship between exchange rate volatility and U.S. poultry exports using a panel data for 49 importing nations over two subperiods: 1976,1985 and 1986,2000. The analysis uses a fixed-effects model specification and three alternative measures of exchange rate volatility. The empirical results suggest that the choice of volatility measure matters as there is a positive relationship between exchange rate uncertainty and poultry exports. These findings are consistent with those from several previous studies. [JEL classification: F310, Q170]. © 2006 Wiley Periodicals, Inc. Agribusiness 22: 233,245, 2006. [source] Differentiating Human Bone from Animal Bone: A Review of Histological MethodsJOURNAL OF FORENSIC SCIENCES, Issue 2 2007Maria L. Hillier M.Sc. ABSTRACT: This review brings together a complex and extensive literature to address the question of whether it is possible to distinguish human from nonhuman bone using the histological appearance of cortical bone. The mammalian species included are rat, hare, badger, racoon dog, cat, dog, pig, cow, goat, sheep, deer, horse, water buffalo, bear, nonhuman primates, and human and are therefore not exhaustive, but cover those mammals that may contribute to a North American or Eurasian forensic assemblage. The review has demonstrated that differentiation of human from certain nonhuman species is possible, including small mammals exhibiting Haversian bone tissue and large mammals exhibiting plexiform bone tissue. Pig, cow, goat, sheep, horse, and water buffalo exhibit both plexiform and Haversian bone tissue and where only Haversian bone tissue exists in bone fragments, differentiation of these species from humans is not possible. Other primate Haversian bone tissue is also not distinguishable from humans. Where differentiation using Haversian bone tissue is undertaken, both the general microstructural appearance and measurements of histological structures should be applied. Haversian system diameter and Haversian canal diameter are the most optimal and diagnostic measurements to use. Haversian system density may be usefully applied to provide an upper and lower limit for humans. [source] Consequences of an Adolescent Onset and Persistent Course of Alcohol Dependence in Men: Adolescent Risk Factors and Adult OutcomesALCOHOLISM, Issue 5 2010Brian M. Hicks Background:, While there is an extensive literature on the correlates of alcohol use disorders (AUD; alcohol abuse and dependence), there are relatively few prospective studies of representative birth cohorts that have examined the unique effects of an adolescent onset and persistent course of AUD on a wide range of psychosocial variables. Methods:, A longitudinal, community-based sample of 530 men was used to examine the impact of an adolescent onset (AUD+ at age 17) and persistent course (AUD+ at age 29) of AUD on adolescent and adult functioning including substance use, antisocial behavior, mental health problems, overall psychosocial functioning, environmental risk and protective factors, and social outcomes such as peer and romantic relationships, marriage, educational and occupational attainment, and parenthood. Results:, An adolescent onset of AUD (n = 57) was associated with severe deficits across multiple domains of psychosocial functioning in adolescence. Measures of behavioral disinhibition in adolescence were strong predictors of a persistent course of AUD (n = 93). Nearly 40% of men with an adolescent onset were able to desist by age 29, and were similar, but not identical to men who never experienced an AUD in terms of adult functioning. Men with an adolescent onset and persistent course of AUD exhibited the most severe deficits in functioning. Conclusion:, Results emphasize the importance of examining developmental course to understand the etiology of AUD. Our findings are optimistic in that individuals who desist from AUD are able to achieve high levels of psychosocial functioning. Our findings suggest that future research on the persistence of AUD into adulthood should focus on the contributions of behavioral disinhibition and social environment variables including peer and romantic relationships. [source] Priming Deficiency in Male Subjects at Risk for Alcoholism: The N4 During a Lexical Decision TaskALCOHOLISM, Issue 12 2009Bangalore N. Roopesh Background:, While there is extensive literature on the relationship between the P3 component of event-related potentials (ERPs) and risk for alcoholism, there are few published studies regarding other potentially important ERP components. One important candidate is the N4(00) component in the context of semantic processing, as abnormalities in this component have been reported for adult alcoholics. Method:, A semantic priming task was administered to nonalcohol dependent male offspring (18 to 25 years) of alcoholic fathers [high risk (HR) n = 23] and nonalcoholic fathers [low risk (LR) n = 28] to study whether the 2 groups differ in terms of the N4 component. Subjects were presented with 150 words and 150 nonwords. Among the words, 50 words (primed) were preceded by their antonyms (prime, n = 50), whereas the remaining 50 words were unprimed. For the analysis, N4 amplitude and latency as well as behavioral measures for the primed and unprimed words were considered. Results:, A significant interaction effect was observed between semantic condition and group, where HR subjects did not show N4 attenuation for primed stimuli. Conclusion:, The lack of N4 attenuation to primed stimuli and/or inability to differentiate between primed and unprimed stimuli, without latency and reaction time being affected, suggest deficits in semantic priming, especially in semantic expectancy and/or postlexical semantic processing in HR male offspring. Further, it indicates that it might be an electrophysiological endophenotype that reflects genetic vulnerability to develop alcoholism. [source] Treatment of acquired hemophilia AJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 5 2007P. W. COLLINS Summary., Acquired hemophilia A (AH) is an autoimmune disease that leads to potentially severe bleeding. Management relies on rapid and accurate diagnosis, control of bleeding episodes and eradication of the inhibitor by immunosuppression. There is extensive literature about the disease but only few controlled data are available. This paper reviews the current literature on treatment strategies for hemostatic therapy and inhibitor eradication. Potential future developments are discussed. [source] Experimental design and taxonomic scope of fragmentation studies on European mammals: current status and future prioritiesMAMMAL REVIEW, Issue 2 2010Alessio MORTELLITI ABSTRACT 1Habitat loss, habitat fragmentation and habitat degradation are the greatest threats to mammals in Europe and the rest of the world. Despite the fact that extensive literature exists, no comprehensive review or synthesis is available to date and this may slow down scientific progress and hamper conservation efforts. 2The goal of this study is to understand if and in what direction progress has been made in the study of the effects of habitat loss and fragmentation on the spatial distribution of European terrestrial mammals. Firstly, we carry out a general synthesis which is structured around 11 key points. The aim of this point-by-point analysis is to identify trends, knowledge gaps and any significant bias in the available literature, and to highlight strengths and shortfalls of the different approaches which have to date been applied. Secondly, we follow a species-specific systematic approach: for each species, we synthesise key results. 3Our results show how substantial progress has been hampered for several reasons including: a large predominance of small-scale field studies of short duration, and a generalised lack of control of: (i) confounding variables; (ii) spatial autocorrelation; and (iii) false absences. Also, despite the relatively high number of studies, few were theoretical studies and even fewer were meta-analyses. The lack of meta-analyses is likely to be due to the small amount of crucial details included in the publications, such as model parameters or information on the landscape context (such as the amount of residual forest cover). 4We synthesise the main results for 14 species. The level of progress is highly variable: for some species, such as the red squirrel Sciurus vulgaris, a series of long-term, large-scale process-oriented studies has allowed an in-depth understanding of its ecology in fragmented landscapes. On the other hand, with other species such as the bank vole Myodes glareolus, despite a relatively large number of field studies, little progress has been made. [source] Critical review of the vector status of Aedes albopictusMEDICAL AND VETERINARY ENTOMOLOGY, Issue 3 2004N. G. Gratz Abstract., The mosquito Aedes (Stegomyia) albopictus (Skuse) (Diptera: Culicidae), originally indigenous to South-east Asia, islands of the Western Pacific and Indian Ocean, has spread during recent decades to Africa, the mid-east, Europe and the Americas (north and south) after extending its range eastwards across Pacific islands during the early 20th century. The majority of introductions are apparently due to transportation of dormant eggs in tyres. Among public health authorities in the newly infested countries and those threatened with the introduction, there has been much concern that Ae. albopictus would lead to serious outbreaks of arbovirus diseases (Ae. albopictus is a competent vector for at least 22 arboviruses), notably dengue (all four serotypes) more commonly transmitted by Aedes (Stegomyia) aegypti (L.). Results of many laboratory studies have shown that many arboviruses are readily transmitted by Ae. albopictus to laboratory animals and birds, and have frequently been isolated from wild-caught mosquitoes of this species, particularly in the Americas. As Ae. albopictus continues to spread, displacing Ae. aegypti in some areas, and is anthropophilic throughout its range, it is important to review the literature and attempt to predict whether the medical risks are as great as have been expressed in scientific journals and the popular press. Examination of the extensive literature indicates that Ae. albopictus probably serves as a maintenance vector of dengue in rural areas of dengue-endemic countries of South-east Asia and Pacific islands. Also Ae. albopictus transmits dog heartworm Dirofilaria immitis (Leidy) (Spirurida: Onchocercidae) in South-east Asia, south-eastern U.S.A. and both D. immitis and Dirofilaria repens (Raillet & Henry) in Italy. Despite the frequent isolation of dengue viruses from wild-caught mosquitoes, there is no evidence that Ae. albopictus is an important urban vector of dengue, except in a limited number of countries where Ae. aegypti is absent, i.e. parts of China, the Seychelles, historically in Japan and most recently in Hawaii. Further research is needed on the dynamics of the interaction between Ae. albopictus and other Stegomyia species. Surveillance must also be maintained on the vectorial role of Ae. albopictus in countries endemic for dengue and other arboviruses (e.g. Chikungunya, EEE, Ross River, WNV, LaCrosse and other California group viruses), for which it would be competent and ecologically suited to serve as a bridge vector. [source] Moral reasoning among physical therapists: results of the defining issues testPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 2 2010Laura Lee Swisher Abstract Background and Purpose.,Although there is extensive literature in other health care fields about the ability to make ethical judgements (moral reasoning), there is a paucity of research addressing the moral reasoning of practising physical therapists. The purposes of this research were to 1) identify the types of moral reasoning used by practising physical therapists as measured by the Defining Issues Test; 2) identify differences in moral reasoning among physical therapists based on educational background, demographic variables, clinical experience, practice setting or expertise in ethics; and 3) compare the moral reasoning of physical therapists with that of other professional groups.,Methods.,The Defining Issues Test of James Rest was used to evaluate moral reasoning. Five hundred thirty-seven physical therapists responded to a mail survey sent to a random sample of 2,000 American Physical Therapy Association members. Twelve physical therapists with expertise in ethics or professionalism completed the same survey.,Results.,The mean postconventional score for the random sample was 41.93. This score was lower than the mean scores of physicians, nurses, medical students, nursing students and dental students established in previous research. Females, ethics experts and those in academic settings had higher postconventional scores.,Conclusions.,Physical therapists scored lower in postconventional moral reasoning than some other professional groups with similar educational background. Factors that may inhibit or enhance the development of moral reasoning among physical therapists and possible consequences of high or low moral reasoning scores in physical therapy require further research. These findings may raise concerns about the entry-level educational curriculum and professional development opportunities in the area of ethics and moral reasoning. Results of this research may also highlight the challenges of evaluation, scholarship and research in physical therapy ethics. Further research and theory development is needed to address the relationships between moral theory and descriptive or empirical research within physical therapy.

Miler Despite the extensive literature on citizens' use of cognitive heuristics in political settings, far less is known about how political elites use these shortcuts. Legislative elites benefit from the efficiency of the accessibility heuristic, but their judgments can also be flawed if accessible information is incomplete or unrepresentative. Using personal interviews and a quasi-experimental design, this paper examines the use of the accessibility heuristic by professional legislative staff when assessing the importance of natural resources issues to their constituents. Staff members recall only a small subset of the relevant constituents in the district, and this subset is biased in favor of active and resource-rich constituents over other, equally relevant constituents. This paper provides a new application of cognitive psychology to political elites and addresses important normative questions about the importance of information processing for political representation. By drawing on the psychology literature on heuristics, this paper identifies the cognitive mechanisms of congressional representation and provides new evidence of old biases. [source] How green is the valley?THE CANADIAN GEOGRAPHER/LE GEOGRAPHE CANADIEN, Issue 3 2005Foreign direct investment in two Norwegian industrial towns Since the early 1900s, foreign direct investments (FDIs) have greatly affected Norwegian society, especially peripheral communities. This article analyses how transnational corporations (TNCs) use territory down to the local level, and how this complex relationship between firms and spaces is shaped by attributes related to the TNC and the characteristics of the local economy. An extensive literature discusses different types of effects and spillovers, such as vertical supply linkages and spin-offs, but theoretical explanations of outcomes are more difficult. The literature links positive as well as negative outcomes to local conditions and to the investment motives of the entity making the FDI, but says little about how these vary with types of business, communities and national economies, and how these interactions generate different outcomes. We conclude that FDIs have different abilities to transform an area. We argue that FDI can trigger path-dependent dependency when it is dominated by economic capital and path-dependent development when it consists of a balance of economic capital, social networks and knowledge. This variation in the effects of FDI is illustrated by an empirical analysis of two industrial towns in Western Norway, one with natural resources and the other with intangible technology resources. Depuis le début des années 1900, les investissements directs à l'étranger (IDE) ont grandement marqué la société norvégienne, notamment dans les communautés périphériques. Cet article présente une analyse de la façon dont les entreprises transnationales (ETN) exploitent le territoire y compris le niveau local. Il tente aussi d'expliquer comment la relation complexe entre les entreprises et les espaces dépend des attributs propres aux ETN et des caractéristiques de l'économie locale. Un courant important de la littérature étudie les nombreuses incidences et répercussions des ETN, comme les relations d'offre verticale et les effets indirects. Cependant, les discussions qui s'ensuivent présentent généralement peu d'explications d'ordre théorique concernant les résultats. La littérature associe les résultats positifs ou négatifs directement aux conditions locales et aux motivations qui poussent une entreprise à placer ses capitaux dans un IDE. Elle aborde à peine la question sur comment les résultats peuvent varier selon les types d'entreprises, de communautés et d'économies nationales, et comment ces interactions produisent des résultats différents. En conclusion, nous rappelons que les IDE disposent de plusieurs possibilités de transformer un milieu. Un investissement peut produire une dépendance au sentier qui accentue la soumission quand le capital économique domine, et une dépendance au sentier qui accentue le développement quand il offre un équilibre entre le capital économique, les réseaux sociaux et le savoir. Une analyse empirique permet de relever cette variation qui caractérise les incidences des IDE. Elle porte sur deux villes moyennes industrielles situées dans la partie occidentale de la Norvège. La première est riche en ressources naturelles tandis que l'autre est dotée de ressources technologiques intangibles. [source] Close Neighbours Matter: Neighbourhood Effects on Early Performance at School,THE ECONOMIC JOURNAL, Issue 523 2007Dominique Goux Children's outcomes are strongly correlated with those of their neighbours. The extent to which this is causal is the subject of an extensive literature. There is an identification problem because people with similar characteristics are observed to live in close proximity. Another major difficulty is that neighbourhoods measured in available data are often considerably larger than those which matter for outcomes (i.e. close neighbours). Several institutional features of France enable us to address these problems. We find that an adolescent's outcomes at the end of junior high-school are strongly influenced by the performance of other adolescents in the neighbourhood. [source] Successful Hepatorenal Transplantation in Hereditary Amyloidosis Caused by a Frame-Shift Mutation in Fibrinogen A,-Chain GeneAMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2006C. Mousson Hereditary systemic amyloidosis comprises several autosomal dominant diseases caused by mutations in a number of plasma proteins, including the fibrinogen A,-chain. Four mutations in the fibrinogen A,-chain that are able to induce amyloidosis have been identified so far, the most common being the Glu526Val mutation. We have observed a family in which the father and his son reached end-stage renal failure because of renal amyloidosis induced by a frame-shift mutation in the fibrinogen A,-chain gene producing a novel amyloid protein. Two kidney transplantations in the father and one in the son resulted in fast graft loss caused by recurrence of amyloid deposition. We then performed hepatorenal transplantation in the son. Three years later, liver and kidney functions are normal without recurrence of amyloid deposition. This case, together with three others with the Glu526Val mutation in the extensive literature, suggests that liver transplantation can cure hereditary fibrinogen amyloidosis, whatever the mutation may be. [source] Diversity, conservation status and threats to native oysters (Ostreidae) around the Atlantic and Caribbean coasts of South AmericaAQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 3 2009Alvar Carranza Abstract 1.Despite the extensive literature on the ecology, systematics and culture of oysters worldwide, an assessment of their diversity, distribution and conservation status for the Atlantic and Caribbean coasts (i.e. depth <50 m) of South America is lacking. Such information is crucial because of the increasing coastal development that threatens most nearshore habitats throughout the region. 2.The available information on oysters on Atlantic and Caribbean coasts is reviewed with a focus on identifying regional conservation priorities based on ecological and socio-economic importance, as well as the magnitude of current or potential threats faced by oyster populations. The current status of ,- taxonomy within the Ostreidae was also examined. 3.Ten species of native Ostreidae (plus three introduced species) inhabit the coastal waters of the Atlantic and Caribbean coasts of South America. 4.Oyster species were ranked according to their biological/ecological and socio-economic value and conservation status within 10 distinct ecoregions. Crassostrea gasar in the Eastern Brazil ecoregion, C. rhizophorae in the Central Caribbean ecoregion and Ostrea puelchana in the North Patagonian Gulfs ecoregion should receive the highest priority for immediate conservation action due to extensive loss of mangrove habitat in the two former regions and evidence of decline of one of the most important populations for the latter. The need for a standardized methodology to assess the status of oyster populations throughout the ecoregions is identified. 5.On a local scale, the allocation of territorial use rights for fisheries under a collaborative/voluntary community framework is strongly advocated to fulfil management, conservation and poverty alleviation goals in these developing countries. Copyright © 2008 John Wiley & Sons, Ltd. [source] Heating of the solar and stellar coronae: a reviewASTRONOMISCHE NACHRICHTEN, Issue 8 2007R. Erdélyi Abstract Despite great advances in observations and modelling, the problem of solar and stellar heating still remains one of the most challenging problems of space physics. To find a definite answer to what sort of mechanisms act to heat the plasma to a few million degrees requires a collaborative effort of small scales observations, large capacity numerical modelling and complicated theoretical approaches. A unique theory should incorporate aspects such as the generation of energy, its transport and dissipation. Up to now, the first two problems are rather clarified. However, the modality of transfer of magnetic or kinetic energy into heat is a question still awaiting for an answer. In the present paper we review the various popular heating mechanisms put forward in the existing extensive literature. The heating processes are, somewhat arbitrarily, classified as hydrodynamic, magnetohydrodynamic or kinetic based on the characteristics of the model medium. These mechanisms are further divided based on the time scales of the ultimate dissipation involved (i.e. AC and DC heating, turbulent heating). In particular, special attention is paid to discuss shock dissipation, mode coupling, resonant absorption, phase mixing, and, reconnection. Finally, we briefly review the various heating mechanisms proposed to heat other stars. (© 2007 WILEY-VCH Verlag GmbH & Co.

Odeh B.A. Clinical predictions of violence are a necessary part of clinical practice despite extensive literature validating the use of actuarial rather than clinical prediction. The current study examined clinicians' use of risk cues in predictions of violence. Clinicians identified several risk cues as significant in clinical assessments of risk, including a history of assaults, hostility, medication noncompliance, paranoid delusions, presence of psychosis, and family problems. However, further results indicated that clinician-endorsed risk cues lack predictive power in the present sample. Copyright © 2006 John Wiley & Sons, Ltd. [source] Fig-eating by vertebrate frugivores: a global reviewBIOLOGICAL REVIEWS, Issue 4 2001MIKE SHANAHAN ABSTRACT The consumption of figs (the fruit of Ficus spp.; Moraceae) by vertebrates is reviewed using data from the literature, unpublished accounts and new field data from Borneo and Hong Kong. Records of frugivory from over 75 countries are presented for 260 Ficus species (approximately 30% of described species). Explanations are presented for geographical and taxonomic gaps in the otherwise extensive literature. In addition to a small number of reptiles and fishes, 1274 bird and mammal species in 523 genera and 92 families are known to eat figs. In terms of the number of species and genera of fig-eaters and the number of fig species eaten we identify the avian families interacting most with Ficus to be Columbidae, Psittacidae, Pycnonotidae, Bucerotidae, Sturnidae and Lybiidae. Among mammals, the major fig-eating families are Pteropodidae, Cercopithecidae, Sciuridae, Phyllostomidae and Cebidae. We assess the role these and other frugivores play in Ficus seed dispersal and identify fig-specialists. In most, but not all, cases fig specialists provide effective seed dispersal services to the Ficus species on which they feed. The diversity of fig-eaters is explained with respect to fig design and nutrient content, phenology of fig ripening and the diversity of fig presentation. Whilst at a gross level there exists considerable overlap between birds, arboreal mammals and fruit bats with regard to the fig species they consume, closer analysis, based on evidence from across the tropics, suggests that discrete guilds of Ficus species differentially attract subsets of sympatric frugivore communities. This dispersal guild structure is determined by interspecific differences in fig design and presentation. Throughout our examination of the fig-frugivore interaction we consider phylogenetic factors and make comparisons between large-scale biogeographical regions. Our dataset supports previous claims that Ficus is the most important plant genus for tropical frugivores. We explore the concept of figs as keystone resources and suggest criteria for future investigations of their dietary importance. Finally, fully referenced lists of frugivores recorded at each Ficus species and of Ficus species in the diet of each frugivore are presented as online appendices. In situations where ecological information is incomplete or its retrieval is impractical, this valuable resource will assist conservationists in evaluating the role of figs or their frugivores in tropical forest sites. [source] Manic symptoms and impulsivity during bipolar depressive episodesBIPOLAR DISORDERS, Issue 3 2007Alan C Swann Objectives:, In contrast to the extensive literature on the frequent occurrence of depressive symptoms in manic patients, there is little information about manic symptoms in bipolar depressions. Impulsivity is a prominent component of the manic syndrome, so manic features during depressive syndromes may be associated with impulsivity and its consequences, including increased risk of substance abuse and suicidal behavior. Therefore, we investigated the prevalence of manic symptoms and their relationships to impulsivity and clinical characteristics in patients with bipolar depressive episodes. Methods:, In 56 bipolar I or II depressed subjects, we investigated the presence of manic symptoms, using Mania Rating Scale (MRS) scores from the Schedule for Affective Disorders and Schizophrenia (SADS), and examined its association with other psychiatric symptoms (depression, anxiety, and psychosis), age of onset, history of alcohol and/or other substance abuse and of suicidal behavior, and measures of impulsivity. Results:, MRS ranged from 0 to 29 (25th,75th percentile, range 4,13), and correlated significantly with anxiety and psychosis, but not with depression, suggesting the superimposition of a separate psychopathological mechanism. Impulsivity and history of substance abuse, head trauma, or suicide attempt increased with increasing MRS. Receiver-operating curve analysis showed that MRS could divide patients into two groups based on history of alcohol abuse and suicide attempt, with an inflection point corresponding to an MRS score of 6. Discussion:, Even modest manic symptoms during bipolar depressive episodes were associated with greater impulsivity, and with histories of alcohol abuse and suicide attempts. Manic symptoms during depressive episodes suggest the presence of a potentially dangerous combination of depression and impulsivity.

The article begins by sorting out what e-learning is, what forms it can take and how significant a phenomenon it has become in the private and public sectors in Canada and elsewhere. Emerging Canadian government e-learning strategies are noted. The authors argue that much existing formal e-learning material is ineffective and set out criteria for identifying viable e-learning approaches. The claim that e-learning provides enhanced access to training is critically examined. The authors also argue that the adoption of e-learning will radically affect the organization of training and its relationship to the wider organization. Finally, the authors critically examine the issue of whether or not e-learning is cheaper than face-to-face instruction. They contend that e-learning can reduce training delivery costs in some circumstances but that the costs associated with developing and delivering effective e-learning will be substantial. Sommaire: On a dit que l'apprentissage en ligne est un moyen efficace et peu coûteux offrant aux fonctionnaires des possibilités de formation continue qui permettront aux organismes du secteur public de recruter et de retenir du personnel qualifié et ainsi d'améliorer leurs résultats organisationnels. Cet article repose sur la documentation concernant l'apprentissage en ligne et l'expérience des auteurs en matière d'élaboration et de prestation de cette méthode d'enseignement afin d'examiner un certain nombre de questions que les gestionnaires du secteur public devraient étudier avant de les adopter. L'article commence par expliquer l'apprentissage en ligne sous ses différentes formes et l'importance de ce phénomène dans les secteurs privé et public au Canada et ailleurs. Les nouvelles stratégies d'apprentissage en ligne du gouvemement canadien sont mentionnées. Les auteurs affirment qu'une grande partie de la documentation officielle sur la question est inefficace et ils présentent des critères pour determiner les méthodes d'apprentissage en ligne qui ont des chances de réussir en matière de formation. Ils examinent d'un ,il critique si cette méthode d'enseignement foumit en fait un meilleur accès è la formation. L'article laisse éggalement entendre que l'adoption de l'apprentissage en ligne transformera radicalement la planification de la formation et ses relations avec l'organisation plus vaste. Enfin, les auteurs examinent attentivement la question de savoir si oui ou non l'apprentissage en ligne est moins coûteux que l'enseignement en personne. Ils soutiennent que cette méhode peut permettre de réduire les coûts de prestation de la formation dans certaines circonstances mais que les coûts associés à l'élaboration et à la prestation de l'apprentissage en ligne efficace seront considérables.
