Selected AbstractsStrategic stakeholder orientations and performance consequences,a case of private nonprofit performing arts in the USINTERNATIONAL JOURNAL OF NONPROFIT & VOLUNTARY SECTOR MARKETING, Issue 1 2010Jasper Hsieh This paper borrows a market orientation perspective in considering how organizations behave toward stakeholders and the implications on performance in the institutional performing arts environment. To investigate the relationship between stakeholder orientations and organizational performance, both interviews and a survey instrument were used. Using nonprofit performing arts organizations in three metropolitan areas of Northwestern US as a sample frame, primary data was collected from leading directors of these organizations. The results generally indicate a positive relationship between stakeholder orientation and organizational performance. Complex relationships between dimensions of stakeholder orientation and performance consequences were also observed. Copyright © 2009 John Wiley & Sons, Ltd.

Long ABSTRACT: To prioritize sites for riparian restoration, resource managers need to understand how recovery processes vary within landscapes. Complex relationships between watershed conditions and riparian development make it difficult to predict the outcomes of restoration treatments in the semiarid Southwest. Large floods in 1993 scoured riparian areas in the Carrizo watershed on the White Mountain Apache Reservation in east-central Arizona. We evaluated recovery at three of these sites using repeated photographs and measurements of channel cross sections and stream-side vegetation along permanent transects. The sites were mapped as lying on the same soil type, had similar streamside vegetative communities, and were similarly treated through livestock exclusion and supplemental seeding. However, the sites and individual reaches within the sites followed strikingly different development paths. Dramatic recovery occurred at a perennial reach where cover of emergent wetland plants increased from 4.7 percent (standard error = 0.8 percent) in October 1995 to 55.5 percent (standard error = 2.7 percent) in September 2001. At several other reaches, geologic and hydro geomorphic characteristics of the sites limited inputs of fine sediment or surface water, resulting in modest or negligible increases in emergent cover. Recovery efforts for highly valued marshlands in this region should prioritize perennial reaches in low gradient valleys where salty sediments are abundant.

Anderson Jr. This article examines the importance of conflict resolution skills and techniques when managing the complex relationships and interdependence necessary for large-scale construction projects. Partnering between multiple public and private organizations is often required in order for these projects to succeed. The authors examine the specific partnering skills that contributed to the success of the Woodrow Wilson Bridge project. [source] Information Processing and Firm-Internal Environment Contingencies: Performance Impact on Global New Product DevelopmentCREATIVITY AND INNOVATION MANAGEMENT, Issue 3 2010Elko Kleinschmidt Innovation in its essence is an information processing activity. Thus, a major factor impacting the success of new product development (NPD) programs, especially those responding to global markets, is the firm's ability to access, share and apply NPD information, which is often widely dispersed, functionally, geographically and culturally. To this end, an IT-communication strength is essential, one that is nested in an internal organizational environment that ensures its effective functioning. Using organizational information processing (OIP) theory as a framework, superior global NPD program performance is shown to result from an effective IT/Communication strength and the commitment components of the firm's internal environment, which are hypothesized to moderate this relationship. IT/Communication strength is identified in this study in terms of two components including the IT/Comm Infrastructure and IT/Comm Capability of the firm, whereas the moderating internal environment of the firm incorporates Resource Commitment and Senior Management Involvement. Data from a major empirical study of international NPD programs (382 SBUs) are used to develop and test this model. Based on a hierarchical regression analysis, the results are substantially supportive, with some unexpected findings. These shed light on the complex relationships of the firm's internal environment, OIP competency, and global NPD program performance. [source] FASHIONS AND FUNDAMENTALISMS IN FIN-DE-SIÈCLE YEMEN: Chador Barbie and Islamic SocksCULTURAL ANTHROPOLOGY, Issue 2 2007ANNE MENELEY This article examines the complex relationships between changing forms of commodity production and consumption and changing styles of religiosity in Zabid, the Republic of Yemen. I examine a couple of prominent logics of veiling in Fin-de-Siècle Yemen: Some reformist women add "Islamic socks" and gloves to their already fully modest garb, while other women don chadors that decorate these garments with embroidery, making them into items of fashionable consumption and adornment. Other commodities, like a Chador Barbie that I found in Yemen's suq, are used to think through changing practices of consumption, adornment, and women's sociability in Zabid. [source] Relationship of glucose regulation to changes in weight: a systematic review and guide to future researchDIABETES/METABOLISM: RESEARCH AND REVIEWS, Issue 5 2010Ching-Ju Chiu Abstract Although weight gain and obesity are risk factors for poor glucose regulation, the relationship, if any, of glucose regulation to changes in weight is not well understood. The purpose of this study was to conduct a systematic review of research examining the relationship of glucose regulation to changes in weight in human-based studies and to provide guidelines for future research in this area. We searched electronic databases and reference sections of relevant articles, including both diabetic and non-diabetic populations, to locate all the literature published before February 2010, and then conducted a systematic review across studies to compare the research designs and findings. The 22 studies meeting our criteria for review generally supported the relationship of glucose regulation to changes in weight. Three studies reported that poor glucose regulation is associated with weight gain; 12 studies concluded that poor glucose regulation is associated with weight loss; 5 showed complex relationships depending on age, sex, or race/ethnicity; and 2 suggested no relationship. The diverse findings may imply that the direction (negative or positive) of the relationship may depend on specific conditions. More research focused on different subpopulations may provide more definitive information supplemental to the current preliminary findings. Recommendations regarding future research in this particular area are provided in the discussion. Copyright © 2010 John Wiley & Sons, Ltd. [source] Why environmental scientists are becoming BayesiansECOLOGY LETTERS, Issue 1 2005James S. Clark Abstract Advances in computational statistics provide a general framework for the high-dimensional models typically needed for ecological inference and prediction. Hierarchical Bayes (HB) represents a modelling structure with capacity to exploit diverse sources of information, to accommodate influences that are unknown (or unknowable), and to draw inference on large numbers of latent variables and parameters that describe complex relationships. Here I summarize the structure of HB and provide examples for common spatiotemporal problems. The flexible framework means that parameters, variables and latent variables can represent broader classes of model elements than are treated in traditional models. Inference and prediction depend on two types of stochasticity, including (1) uncertainty, which describes our knowledge of fixed quantities, it applies to all ,unobservables' (latent variables and parameters), and it declines asymptotically with sample size, and (2) variability, which applies to fluctuations that are not explained by deterministic processes and does not decline asymptotically with sample size. Examples demonstrate how different sources of stochasticity impact inference and prediction and how allowance for stochastic influences can guide research. [source] Families and Health: An Empirical Resource Guide for Researchers and PractitionersFAMILY RELATIONS, Issue 4 2009Christine M. Proulx As evidence mounts indicating that the quality of family relationships affects family member health and that the health of family members influences the quality of family relationships and family functioning, it becomes crucial for family scientists to determine and understand the mechanisms underlying these associations. An empirical resource guide for researchers and practitioners focusing on the complex relationships between family relationships, context, health, intervention, and treatment is presented. [source] Psychiatric endophenotypes and the development of valid animal modelsGENES, BRAIN AND BEHAVIOR, Issue 2 2006T. D. Gould Endophenotypes are quantifiable components in the genes-to-behaviors pathways, distinct from psychiatric symptoms, which make genetic and biological studies of etiologies for disease categories more manageable. The endophenotype concept has emerged as a strategic tool in neuropsychiatric research. This emergence is due to many factors, including the modest reproducibility of results from studies directed toward etiologies and appreciation for the complex relationships between genes and behavior. Disease heterogeneity is often guaranteed, rather than simplified, through the current diagnostic system; inherent benefits of endophenotypes include more specific disease concepts and process definitions. Endophenotypes can be neurophysiological, biochemical, endocrine, neuroanatomical, cognitive or neuropsychological. Heritability and stability (state independence) represent key components of any useful endophenotype. Importantly, they characterize an approach that reduces the complexity of symptoms and multifaceted behaviors, resulting in units of analysis that are more amenable to being modeled in animals. We discuss the benefits of more direct interpretation of clinical endophenotypes by basic behavioral scientists. With the advent of important findings regarding the genes that predispose to psychiatric illness, we are at an important crossroads where, without anthropomorphizing, animal models may provide homologous components of psychiatric illness, rather than simply equating to similar (loosely analogized) behaviors, validators of the efficacy of current medications or models of symptoms. We conclude that there exists a need for increased collaboration between clinicians and basic scientists, the result of which should be to improve diagnosis, classification and treatment on one end and to increase the construct relevance of model organisms on the other. [source] Modeling the effects of fire and climate change on carbon and nitrogen storage in lodgepole pine (Pinus contorta) standsGLOBAL CHANGE BIOLOGY, Issue 3 2009E. A. H. SMITHWICK Abstract The interaction between disturbance and climate change and resultant effects on ecosystem carbon (C) and nitrogen (N) fluxes are poorly understood. Here, we model (using CENTURY version 4.5) how climate change may affect C and N fluxes among mature and regenerating lodgepole pine (Pinus contorta var. latifolia Engelm. ex S. Wats.) stands that vary in postfire tree density following stand-replacing fire. Both young (postfire) and mature stands had elevated forest production and net N mineralization under future climate scenarios relative to current climate. Forest production increased 25% [Hadley (HAD)] to 36% [Canadian Climate Center (CCC)], compared with 2% under current climate, among stands that varied in stand age and postfire density. Net N mineralization increased under both climate scenarios, e.g., +19% to 37% (HAD) and +11% to 23% (CCC), with greatest increases for young stands with sparse tree regeneration. By 2100, total ecosystem carbon (live+dead+soils) in mature stands was higher than prefire levels, e.g., +16% to 19% (HAD) and +24% to 28% (CCC). For stands regenerating following fire in 1988, total C storage was 0,9% higher under the CCC climate model, but 5,6% lower under the HAD model and 20,37% lower under the Control. These patterns, which reflect variation in stand age, postfire tree density, and climate model, suggest that although there were strong positive responses of lodgepole pine productivity to future changes in climate, C flux over the next century will reflect complex relationships between climate, age structure, and disturbance-recovery patterns of the landscape. [source] Amazon drought and its implications for forest flammability and tree growth: a basin-wide analysisGLOBAL CHANGE BIOLOGY, Issue 5 2004Daniel Nepstad Abstract Severe drought in moist tropical forests provokes large carbon emissions by increasing forest flammability and tree mortality, and by suppressing tree growth. The frequency and severity of drought in the tropics may increase through stronger El Niño Southern Oscillation (ENSO) episodes, global warming, and rainfall inhibition by land use change. However, little is known about the spatial and temporal patterns of drought in moist tropical forests, and the complex relationships between patterns of drought and forest fire regimes, tree mortality, and productivity. We present a simple geographic information system soil water balance model, called RisQue (Risco de Queimada , Fire Risk) for the Amazon basin that we use to conduct an analysis of these patterns for 1996,2001. RisQue features a map of maximum plant-available soil water (PAWmax) developed using 1565 soil texture profiles and empirical relationships between soil texture and critical soil water parameters. PAW is depleted by monthly evapotranspiration (ET) fields estimated using the Penman,Monteith equation and satellite-derived radiation inputs and recharged by monthly rain fields estimated from 266 meteorological stations. Modeled PAW to 10 m depth (PAW10 m) was similar to field measurements made in two Amazon forests. During the severe drought of 2001, PAW10 m fell to below 25% of PAWmax in 31% of the region's forests and fell below 50% PAWmax in half of the forests. Field measurements and experimental forest fires indicate that soil moisture depletion below 25% PAWmax corresponds to a reduction in leaf area index of approximately 25%, increasing forest flammability. Hence, approximately one-third of Amazon forests became susceptible to fire during the 2001 ENSO period. Field measurements also suggest that the ENSO drought of 2001 reduced carbon storage by approximately 0.2 Pg relative to years without severe soil moisture deficits. RisQue is sensitive to spin-up time, rooting depth, and errors in ET estimates. Improvements in our ability to accurately model soil moisture content of Amazon forests will depend upon better understanding of forest rooting depths, which can extend to beyond 15 m. RisQue provides a tool for early detection of forest fire risk. [source] Effect of regulatory oversight on the association between internal governance characteristics and audit feesACCOUNTING & FINANCE, Issue 1 2008El'fred Boo G34; M42; N40 Abstract We examine the relationship between internal governance, external audit monitoring and regulatory oversight for a sample comprising industrial companies and financial/utility companies subject to additional industry-specific regulation. Our results indicate that the association between audit fees and board/audit committee independence and size are weaker for regulated companies. These observations are consistent with the notion that regulatory oversight partially substitutes the external audit as a monitoring mechanism. However, boards/audit committees with more multiple directorships demand a more extensive audit in the presence of regulatory oversight to protect their reputation capital. Our study enhances our understanding of the complex relationships among the major corporate governance elements. [source] How leveraging human resource capital with its competitive distinctiveness enhances the performance of commercial and public organizationsHUMAN RESOURCE MANAGEMENT, Issue 4 2005Abraham Carmeli Although scholars agree that complex relationships between organizations' actual human resources (i.e., human capital stock) and means of leveraging these resources may influence performance, little empirical work has tested such propositions directly. We collected two primary data sets from privateand public-sector organizations in Israel. The multiplicative interaction between perceived human resources capital and distinctive value derived from that HR capital was significantly related to various measures of perceived and objective organizational performance. Having higher levels of human resources capital was strongly associated with performance only when top managers perceived that these resources provided distinctive value in terms of being highly valuable, inimitable, rare, and nonsubstitutable. We discuss the implications of these findings for research on strategic human resource management and the resource-based view of competitive advantage, as well as for practical efforts to develop firm-specific human resource capital that is inherently distinctive. © 2005 Wiley Periodicals, Inc. [source] A longitudinal evaluation of two-year outcome in a community-based mental health service using graphical chain modelsINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2004The South-Verona Outcome Project Abstract The 2-year outcome of 178 patients attending a community-based mental health service was assessed from a multidimensional perspective. The study investigated: (1) the effect of disease-related characteristics (such as diagnosis and illness duration) and of a series of outcome variables measured at baseline (global functioning, psychopathology, social disability, quality of life and satisfaction with services) on total costs of care over 2 years; and (2) the effect of costs of care and outcome variables measured at baseline on the corresponding outcome variables at 2 years. To gain insight into the multivariate longitudinal dependencies among variables, we used graphical Gaussian chain models, a new multivariate method that analyses the relationship between continuous variables taking into account the effect of antecedent and intervening variables, to reveal not only direct but also indirect correlations. Outcome variables showed the tendency to segregate, both at baseline and follow-up, into two distinct groups: a clinician-rated dimension (given by global functioning, social disability and psychopathology) and a patient-rated dimension (given by service satisfaction and subjective quality of life). Higher costs at 2 years were predicted by higher psychopathology at baseline, diagnosis of psychosis and longer duration of illness. Baseline values for each variable were the main predictors of the corresponding values at two years. Improvement in satisfaction with life at follow-up was experienced in those subjects with a lower functioning at baseline. This study throws some light on the complex relationships between clinical, social and economic variables affecting the medium-term outcome of mental health care.

[source] The role of law in welfare reform: critical perspectives on the relationship between law and social work practiceINTERNATIONAL JOURNAL OF SOCIAL WELFARE, Issue 1 2006Suzy Braye This article considers the complex relationships between law, welfare policy and social work practice, in order to address the question of what role legal frameworks might play in achieving welfare policy and professional practice goals. It traces how law has developed as a core component of professional practice, and challenges some of the false expectations placed upon it. It then draws on findings from an international knowledge review of law teaching in social work education to propose a model for understanding how professional practice incorporates legal perspectives, and proposes ways in which legal frameworks can provide positive and constructive vehicles for accountable practice. [source] International Labour Migrants' Return to Meiji-era Yamaguchi and Hiroshima: Economic and Social EffectsINTERNATIONAL MIGRATION, Issue 3 2008Jonathan Dresner International labour migration from Meiji era (1868,1912) Japan was intensely concentrated: over 60 per cent of the 29,000 participants in the government-managed Hawai'i emigration programme (kan'yaku imin, 1885,1894) came from seven coastal counties around the Hiroshima-Yamaguchi prefectural border in southwest Japan. Almost half of the emigrants became long-term settlers instead of returning to their hometowns, but this paper examines what happened to returning emigrants and to their home communities. Since the migration was primarily economic in nature, the effect of migrant earnings was carefully monitored and is frequently cited by scholars. Surveys showed high rates of debt repayment and savings, and improved living conditions, but investment and entrepreneurship were limited. High-emigration regions rarely became economic centers of any importance. Less carefully studied are non-economic effects, partially because the labour programme was structured to minimize contact with Hawaiian or Caucasian culture, and thus returnees had little cultural experience to transfer to their hometowns. Local officials in Yamaguchi seemed proud of the lack of social change. Even long-term sojourners, who returned due to family needs after a decade or more overseas, exhibited no readjustment difficulties. Returnees, particularly in Yamaguchi, sometimes moved on to Japanese colonial territories, creating multilateral and complex relationships with overseas communities. This sojourning migration, like contemporary analogs, was a powerful form of poverty relief in the midst of dislocating globalization, but did not produce a rise in entrepreneurship or a Westernization of local culture. Because this sojourning migration was structurally similar to our modern-day patterns, it provides evidence of the longevity of those patterns and the possible long-term effects, and raises questions about our expectations for migration policy. Retour des travailleurs migrants internationaux de l'ère Meiji à Yamaguchi et Hiroshima: effets économiques et sociaux Au Japon, la migration internationale de main-d',uvre de l'ère Meiji (1868,1912) a été très concentrée: plus de soixante pour cent des 29 000 participants au programme gouvernemental d'émigration à destination d'Hawaï (kan'yaku imin, 1885-1894) venaient de sept régions côtières proches de la limite entre les préfectures d'Hiroshima et de Yamaguchi dans le Sud-Ouest du Japon. Sachant que la moitié des émigrants sont devenus des résidents de longue durée et ne sont pas rentrés dans leur communauté d'origine, le présent document s'intéresse à ceux qui ont fait le choix inverse. Etant donné que cette migration était principalement de nature économique, les effets des gains des migrants ont étéétudiés avec attention et sont souvent cités par les chercheurs. Si des enquêtes ont révélé des taux importants de remboursement de dettes et d'épargne, ainsi qu'un niveau de vie en hausse, les investissements et la création d'entreprises, en revanche, sont restés limités. On a rarement vu des régions à fort taux d'émigration devenir des centres économiques d'importance. Les effets non économiques ont été moins étudiés, en partie parce que ce programme de main-d',uvre était structuré de façon à réduire le plus possible les contacts avec la culture hawaïenne ou caucasienne, ce qui fait que les rapatriés n'avaient guère d'acquis culturels exogènes à transmettre. Les responsables locaux de Yamaguchi semblaient d'ailleurs se réjouir de l'absence de changements sociaux. Même les résidents de longue durée, qui étaient rentrés pour raisons familiales au bout d'au moins une décennie à l'étranger, ne montraient aucune difficultéà se réadapter. Les rapatriés, en particulier à Yamaguchi, ont parfois déménagé vers les territoires coloniaux japonais, créant des relations multilatérales complexes avec les communautés de l'outre-mer. Cette migration temporaire, comme les mouvements analogues à la même époque, était une formidable façon de réduire la pauvreté dans un contexte de bouleversement mondial, mais elle n'a pas renforcé l'esprit d'entreprise ni conduit à une occidentalisation de la culture locale. Comme cette migration temporaire était structurellement semblable à nos modèles contemporains, elle témoigne de la longue durée de vie de ces modèles et de leurs effets possibles à long terme, et soulève des questions quant à nos attentes en matière de politique migratoire. Retorno a los trabajadores migrantes internacionales a la era Meiji en Yamaguchi e Hiroshima: Efectos socioeconómicos La migración laboral internacional en la era Meiji del Japón (1868,1912) era sumamente concentrada: más del 60 por ciento de los 29.000 participantes en el programa de emigración Hawai'i (kan'yaku imin, 1885-1894) administrado por el Gobierno, provenía de varios condados costeros en torno a la frontera prefectural entre Hiroshima-Yamaguchi en el sudeste del Japón. Casi la mitad de los emigrantes residía en albergues semipermanentes y no retornaban a sus lugares de origen. Ahora bien, en este artículo se examina lo ocurrido con los migrantes que retornaron y con las comunidades de retorno. Habida cuenta que la migración era mayormente de carácter económico, el efecto de los ingresos de los migrantes se siguió de cerca y, frecuentemente, ha sido citado por los estudiosos en la materia. Las encuestas demuestran elevadas tasas de reembolso de deudas y de ahorro, así como un mejoramiento de las condiciones de vida, pero también apuntan a limitadas inversiones o empresas. Las regiones de alta emigración rara vez se convirtieron en centros de importancia económica. No se ha estudiado en detalle los efectos extra económicos, en parte porque el programa de migración laboral estaba estructurado para minimizar el contacto con la cultura hawaiana o caucasiana, por lo cual las personas que retornaban tenían poca experiencia cultural que aportar a sus lugares de origen. Los funcionarios locales en Yamaguchi se enorgullecían de la falta de intercambio social. Incluso aquéllos residentes de larga duración que retornaron debido a cuestiones familiares tras una década o más en ultramar, no presentaron ninguna dificultad en readaptarse. Las personas que retornaron, particularmente a Yamaguchi, se desplazaron a veces a territorios coloniales japoneses, estableciendo complejas relaciones multilaterales con comunidades en ultramar. La migración de carácter permanente, al igual que sus análogos contemporáneos, era un sólido medio de aliviar la pobreza en medio de una globalización perturbadora, pero no dio lugar a un incremento empresarial o a una occidentalización de la cultura local. La similitud estructural de la migración de larga duración con nuestros patrones de hoy en día, aporta pruebas de la longevidad de los mismos, de los posibles efectos a largo plazo de dichos patrones y plantea una serie de preguntas sobre las expectativas en cuanto a las políticas migratorias. [source] Problem-solving competency of nursing graduatesJOURNAL OF ADVANCED NURSING, Issue 5 2004Leana R. Uys DSocSc Aim., This paper reports a study describing and evaluating the outcomes of problem-based learning (PBL) programmes in nursing schools in South Africa in terms of the competence of graduates to solve problem in actual clinical settings, and comparing this competence with that of graduates from non-PBL programmes. Background., The nursing literature tends to equate problem-solving with patient-centred problems or the nursing process. However, it is also a skill used in managing the work role, working in a team and managing a health care unit. Problem-solving refers to the process of selectively attending to information in a patient care setting. The investigation of problem-solving in nursing is complicated by the complex relationships between different cognitive processes. Methods., A qualitative evaluation study, descriptive and comparative in nature, was carried out. In-depth interviews were held with graduates and their supervisors, asking them to identify problem-solving incidents in which they had been involved. Template analysis style and Benner's interpretive approach were used to analyse the data. Findings., The majority of the incidents described by the graduates (84%) were graded at the advanced beginner level or above. The majority of incidents at the novice level came from the non-PBL group. ,Using people skills' and ,being assertive' were the two problem-solving strategies most often used. The PBL group fared better than the non-problem-based group in the level of their problem-solving ability. Conclusion., The findings of this study suggest that further research is warranted into the problem-solving abilities of PBL graduates, their personal development over time and at different stages of practice. In addition, it would be interesting to follow the development of their problem-solving abilities over time. [source] Metabolic rate models and the substitutability of predator populationsJOURNAL OF ANIMAL ECOLOGY, Issue 2 2004David R. Chalcraft Summary 1Much of the debate surrounding the consequences of biodiversity loss centres around the issue of whether different species are functionally similar in their effects on ecological processes. In this study, we examined whether populations consisting of smaller, more abundant individuals are functionally similar to populations of the same species with larger, fewer individuals. 2We manipulated the biomass and density of banded sunfish (Enneacanthus obesus) and measured their impact on populations of Southern leopard frog (Rana sphenocephala) larvae. We also evaluated the ability of models relating metabolic rate to body size to predict the relative impacts of populations that differ in average body size and population density. 3Our results indicate that population biomass, density and their interaction each play a large role in determining the effect of a predator population on its food resource. Populations with smaller but more abundant individuals had effects as large or larger than those populations with larger but fewer individuals. 4Although we found qualitative agreement between the observed relative effects of populations with that predicted by allometric models, we also found that density-dependence can cause effects of a population to differ from that expected based on allometry. 5The substitutability of populations differing in average body size appears to depend on complex relationships between metabolic rate, population density and the strength of density-dependence. The restrictive conditions necessary to establish functional equivalence among different populations of the same species suggests that functional equivalence should be rare in most communities. [source] Mobile discourse: political bumper stickers as a communication event in IsraelJOURNAL OF COMMUNICATION, Issue 2 2000L-R Bloch The use of political bumper stickers in Israel began as a spontaneous protest medium, evolving into a routinized form of public discourse, taking place throughout the year, independently of national elections. The rules of interaction of this nontraditional means of political communication are identified and the complex relationships between the messages within their social situation are investigated using an ethnographic model. This analysis reveals that the medium does indeed constitute a structured means of expression with identifiable forms, rules, and usages, affording the person in the street a way of participating in the national discourse, bypassing traditional avenues of influence. The detailed examination of a single political bumper sticker reveals a structure parallel to the overall code, further demonstrating the intricacy of the messages. The analysis shows how this political discourse reflects social norms peculiar to Israel and how its use has become an affirmation of cultural identity. Because the fundamental properties of political bumper stickers have now been exposed, it is possible to examine how the actual use of this medium changes the structure of political agency in society through the presumption that ordinary individuals have the right of access to the public debate of national political issues, a right heretofore exclusively the prerogative of institutional power holders. [source] Ideology, Context, and Obligations to Assist Older PersonsJOURNAL OF MARRIAGE AND FAMILY, Issue 4 2002Timothy Killian Are older adults responsible for meeting their own needs, is it their children's obligation to care for them, or is there a collective responsibility to see that older adults have their needs met? The purpose of this study was to examine the normative obligations of individuals, family members, and the government to provide for the needs of older adults. The authors examined how ideological beliefs and contextual circumstances are related to beliefs about obligations to older persons. Data were collected from phone interviews of a sample of 270 adults who were over 40 years old. The results indicate that ideological beliefs were better predictors of normative obligations than were contextual variables. Future research should reflect the complex relationships among ideological beliefs, contextual circumstances, and normative obligation beliefs. [source] Latent errors and adverse organizational consequences: a conceptualizationJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 7 2003Rangaraj Ramanujam We develop the concept of latent errors,uncorrected deviations from procedures and policies that have no direct adverse consequences,and examine the complex relationships between organizational antecedents, latent errors, and adverse consequences. Latent errors, with varying levels of frequency, are present in all organizations whereas extreme adverse outcomes are rare. Thus, all organizations become potential objects of study in research on errors. Latent errors enable the design of ex ante studies of errors that avoid sampling on the dependent variable. The basic elements of our framework focus on two critical linkages. First is the role of antecedent factors such as incentives and goals in contributing to the presence of latent errors. Second, we explore how positive and negative feedback systems and external triggers link an acceleration of latent errors with adverse organizational outcomes. We also discuss how variations in context (e.g., whether work activities are co-located or distributed) may affect these factors. Implications for research on high-reliability organizations are discussed. Copyright © 2003 John Wiley & Sons, Ltd. [source] Religion as Culture: Religious Individualism and Collectivism Among American Catholics, Jews, and ProtestantsJOURNAL OF PERSONALITY, Issue 4 2007Adam B. Cohen ABSTRACT We propose the theory that religious cultures vary in individualistic and collectivistic aspects of religiousness and spirituality. Study 1 showed that religion for Jews is about community and biological descent but about personal beliefs for Protestants. Intrinsic and extrinsic religiosity were intercorrelated and endorsed differently by Jews, Catholics, and Protestants in a pattern that supports the theory that intrinsic religiosity relates to personal religion, whereas extrinsic religiosity stresses community and ritual (Studies 2 and 3). Important life experiences were likely to be social for Jews but focused on God for Protestants, with Catholics in between (Study 4). We conclude with three perspectives in understanding the complex relationships between religion and culture. [source] Should service user involvement be consigned to history?JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 5 2006A critical realist perspective Service user involvement in the UK healthcare agenda is now widely expected. Historically, service user groups have been increasingly successful in their demands for greater involvement. Hierarchies of involvement exist that include consultation and partnership working. Psychiatry is an archetypal arena in terms of power and control. The traditional view of interpreting the place of service users within this arena is that the service user is at the bottom of this hierarchy; involvement allows transcendence of the power hierarchy. Critical realist theory is offered as an alternative approach to understanding these complex relationships. It is argued that contemporary models of involvement perpetuate and sustain the power positions of the dominant discourse within psychiatry. It is suggested that a critical realism perspective, offers a model that does not kowtow to the dominant discourse but rather recognizes that service users now possess power, especially in terms of being able to provide services that statutory services providers now require. Is it time for service users to call the tune, and, in doing so, establish a power position outside the traditional hierarchy of power? [source] R×C ecological inference: bounds, correlations, flexibility and transparency of assumptionsJOURNAL OF THE ROYAL STATISTICAL SOCIETY: SERIES A (STATISTICS IN SOCIETY), Issue 1 2009D. James Greiner Summary., Despite its potential pitfalls, ecological inference is an unavoidable part of some quantitative settings, including US voting rights litigation. In such applications, the analyst will typically encounter two-way tables with more than two rows and columns. Although several ecological inference methods are currently available for 2×2 tables, there are fewer options for analysing general R×C tables, and virtually none that model counts as opposed to fractions. We propose a count R×C method that respects the bounds deterministically, that allows for complex relationships between internal cell quantities, that is easily extensible and that results from transparent assumptions. We study the method via simulation, and then apply it to an example that is drawn from the state of Texas relevant to recent redistricting litigation there. [source] Re-founding Representation: Wider, Broader, Closer, DeeperPOLITICAL STUDIES REVIEW, Issue 2 2010Lucy Taylor This article challenges conventional understandings and methodologies associated with the study of political representation. It imagines representation as a power relationship and shifts attention from elections to a closer examination of the interface between representatives and those they claim to represent. It argues for the need to make representation studies wider, moving our focus to study polities beyond the confines of prosperous, established democracies. Secondly, we should broaden our understanding of representation agents in two ways. We should consider how non-voters are represented and we should include diverse forms of social organisations, problematising relationships of representation within these groups and taking their political-representational role seriously. Thirdly, we should move closer, conducting not only macro-level analyses but also micro-level studies, exploring representation among and between individuals and groups in order to understand the complex relationships, motives and dynamics of power at work. Finally we need to go deeper, looking at our own subject positions as scholars critically and challenging the neutrality of the ideas and assumptions that we use as intellectual tools. Moreover, we should promote deeper relationships of representation, reconnecting it to ideas and practices of participation, and promoting the role of accountability in ,closing the loop' and enhancing democracy. [source] PERSUASION AS GOVERNANCE: A STATE-CENTRIC RELATIONAL PERSPECTIVEPUBLIC ADMINISTRATION, Issue 3 2010STEPHEN BELL Debates about governance and the relationship between governance and government have focused upon markets, hierarchies and networks as principal modes of governance. In this paper we argue that persuasion constitutes a further and distinctive mode of governance, albeit one which interpenetrates other modes of governance. In order to assess the nature, limitations and scope of persuasion and the complex relationships between markets, hierarchies, networks on the one hand and persuasion on the other, we interpret persuasion through the prism of two theoretical perspectives on governance. We argue that the society-centred perspective usefully draws our attention to the role played by non-state actors in the exercise of governance through persuasion but that a state-centric relational account can help us to better understand important facets of persuasion as a mode of governance. [source] Reinventing government through on-line citizen involvement in the developing world: a case study of taipei city mayor's e-mail box in Taiwan,PUBLIC ADMINISTRATION & DEVELOPMENT, Issue 5 2006Don-Yun Chen Abstract Since the 1980s, a global administrative reform movement is reshaping the relationship between citizens and state. A major concern is how government can be more responsive to the governed through citizen participation. However, the more citizens participate, the more costly it is to govern. And the application of new information and communication technology (ICT) seems to be a cure for this limitation. In this research, authors take the Taipei City Mayor's e-mail-box (TCME) in Taiwan as a case to illustrate the complex relationships among citizen involvement, e-government and public management. After a series of empirical investigations, the authors show that although ICT can reduce the cost of citizen involvement in governing affairs, it cannot increase citizens' satisfaction with government activities without reforming the bureaucratic organisation, regulatory structure, and managerial capacities of the public sector. The results could be helpful to public managers in planning and evaluating online governmental services in the developing countries. Copyright © 2006 John Wiley & Sons, Ltd. [source] Nurse staffing and medication errors: Cross-sectional or longitudinal relationships?,RESEARCH IN NURSING & HEALTH, Issue 1 2009Barbara A. Mark Abstract We used autoregressive latent trajectory (ALT) modeling to examine the relationship between change in nurse staffing and change in medication errors over 6 months in 284 general medical-surgical nursing units. We also investigated the impact of select hospital and nursing unit characteristics on the baseline level and rate of change in medication errors. We found essentially no support for a nurse staffing,medication error relationship either cross-sectionally or longitudinally. Few hospital or nursing unit characteristics had significant relationships to either the baseline level or rate of change in medication errors. However, ALT modeling is a promising technique that can promote a deeper understanding of the theoretically complex relationships that may underlie the nurse staffing,medication error relationship. © 2008 Wiley Periodicals, Inc.

Robbins Abstract An agent-based model was developed to simulate the growth rate, age structure, and social system of the endangered mountain gorillas (Gorilla beringei beringei) in the Virunga Volcanoes region. The model was used to compare two types of data: 1) estimates of the overall population size, age structure, and social structure, as measured by six censuses of the entire region that were conducted in 1971,2000; and 2) information about birth rates, mortality rates, dispersal patterns, and other life history events, as measured from three to five habituated research groups since 1967. On the basis of the research-group data, the "base simulation" predicted a higher growth rate than that observed from the census data (3% vs. 1%). This was as expected, because the research groups have indeed grown faster than the overall population. Additional simulations suggested that the research groups primarily have a lower mortality rate, rather than higher birth rates, compared to the overall population. Predictions from the base simulation generally fell within the range of census values for the average group size, the percentage of multimale groups, and the distribution of females among groups. However, other discrepancies predicted from the research-group data were a higher percentage of adult males than observed, an overestimation of the number of multimale groups with more than two silverbacks, and an overestimated number of groups with only two or three members. Possible causes for such discrepancies include inaccuracies in the census techniques used, and/or limitations with the long-term demographic data set obtained from only a few research groups of a long-lived species. In particular, estimates of mortality and male dispersal obtained from the research groups may not be representative of the entire population. Our final simulation addressed these discrepancies, and provided a better basis for further studies on the complex relationships among individual life history events, group composition, population age structure, and growth rate patterns.

[source] Tumour virology , history, status and future challengesAPMIS, Issue 5-6 2009KARL-HENNING KALLAND Viruses enter host cells in order to complete their life cycles and have evolved to exploit host cell structures, regulatory factors and mechanisms. The virus and host cell interactions have consequences at multiple levels, spanning from evolution through disease to models and tools for scientific discovery and treatment. Virus-induced human cancers arise after a long duration of time and are monoclonal or oligoclonal in origin. Cancer is therefore a side effect rather than an essential part of viral infections in humans. Still, 15,20% of all human cancers are caused by viruses. A review of tumour virology shows its close integration in cancer research. Viral tools and experimental models have been indispensible for the progress of molecular biology. In particular, retroviruses and DNA tumour viruses have played major roles in our present understanding of the molecular biology of both viruses and the host. Recently, additional complex relationships due to virus and host co-evolution have appeared and may lead to a further understanding of the overall regulation of gene expression programmes in cancer.
