Clinical and Economic Factors Associated with Ambulance Use to the Emergency Department

ACADEMIC EMERGENCY MEDICINE, Issue 8 2006
Jennifer Prah Ruger PhD
Background: Concern about ambulance diversion and emergency department (ED) overcrowding has increased scrutiny of ambulance use. Knowledge is limited, however, about clinical and economic factors associated with ambulance use compared to other arrival methods. Objectives: To compare clinical and economic factors associated with different arrival methods at a large, urban, academic hospital ED. Methods: This was a retrospective, cross-sectional study of all patients seen during 2001 (N= 80,209) at an urban academic hospital ED. Data were obtained from hospital clinical and financial records. Outcomes included acuity and severity level, primary complaint, medical diagnosis, disposition, payment, length of stay, costs, and mode of arrival (bus, car, air-medical transport, walk-in, or ambulance). Multivariate logistic regression identified independent factors associated with ambulance use. Results: In multivariate analysis, factors associated with ambulance use included: triage acuity A (resuscitation) (adjusted odds ratio [OR], 51.3; 95% confidence interval [CI] = 33.1 to 79.6) or B (emergent) (OR, 9.2; 95% CI = 6.1 to 13.7), Diagnosis Related Group severity level 4 (most severe) (OR, 1.4; 95% CI = 1.2 to 1.8), died (OR, 3.8; 95% CI = 1.5 to 9.0), hospital intensive care unit/operating room admission (OR, 1.9; 95% CI = 1.6 to 2.1), motor vehicle crash (OR, 7.1; 95% CI = 6.4 to 7.9), gunshot/stab wound (OR, 2.1; 95% CI = 1.5 to 2.8), fell 0,10 ft (OR, 2.0; 95% CI = 1.8 to 2.3). Medicaid Traditional (OR, 2.0; 95% CI = 1.4 to 2.4), Medicare Traditional (OR, 1.8; 95% CI = 1.7 to 2.1), arrived weekday midnight,8 AM (OR, 2.0; 95% CI = 1.8 to 2.1), and age ,65 years (OR, 1.3; 95% CI = 1.2 to 1.5). Conclusions: Ambulance use was related to severity of injury or illness, age, arrival time, and payer status. Patients arriving by ambulance were more likely to be acutely sick and severely injured and had longer ED length of stay and higher average costs, but they were less likely to have private managed care or to leave the ED against medical advice, compared to patients arriving by independent means.

The Relationship Between Economic Factors and Equity Markets in Central Europe

THE ECONOMICS OF TRANSITION, Issue 3 2000
Jan Hanousek
This paper investigates the possibility that newly-emerging equity markets in Central Europe exhibit semi-strong form efficiency such that no relationship exists between lagged values of changes in economic variables and changes in equity prices. We find that while there are connections between the real economy and equity market returns in Poland and Hungary, these links occur with lags, suggesting the possibility of profitable trading strategies based on public information and rejecting semi-strong efficiency. For the Czech Republic the situation is more complex. In recent periods, little connection exists between lagged economic variables and equity market returns. Although this finding might be viewed as consistent with semi-strong efficiency, in fact there is also little connection between current economic values and stock prices in the Czech Republic. Thus, instead of processing information efficiently, the Czech market appears to be entirely divorced from the real world. It is suggested that the difference in the current status of these markets may be due to the different methods by which they were created. [source]

Mad tales from Bollywood: the impact of social, political, and economic climate on the portrayal of mental illness in Hindi films

ACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2005
D. Bhugra
Objective:, To study the portrayal of mental illness (especially psychosis) in Hindi films since 1950 and to study the influence of prevalent social, political and economic factors on each portrayal. Method:, Using two encyclopaedias and one source book, films that had mental illness affecting one of the protagonists were identified. The social, economic and political factors were identified using history texts. Results:, In the 1960s after India became a Republic, the political climate was one of idealism and as a result the portrayal of mental illness was gentle, more international in its outlook, and used psychoanalytic techniques. In the 1970s and 1980s, as a result of increased political and bureaucratic corruption and an unstable political climate, the portrayals became harder and psychopaths were portrayed more often. In the 1980s, the trend continued with female psychopaths, and avenging women emerged as a major force because the political and judicial systems were seen as impotent in delivering justice. In the 1990s, following economic liberalization, the women were seen and used as possessions in society and the cinema, and portrayals of stalking and morbid jealousy increased. Conclusion:, Hindi films since the 1950s appear to have been influenced by changing cultural norms which in turn affected the way mental illness is portrayed. [source]


Alcohol policy in South Africa: a review of policy development processes between 1994 and 2009

ADDICTION, Issue 8 2010
Charles D. H. Parry
ABSTRACT Background Implementation of effective policies to reduce harmful alcohol consumption requires both a good understanding of the policy development process and which strategies are likely to work. Aims To contribute to this understanding by reviewing four specific policy development initiatives that have taken place in South Africa between 1994 and 2009: restrictions on alcohol advertising and counter-advertising, regulation of retail sales of alcohol, alcohol taxation and controls on alcohol packaging. Methods Material was drawn from a record of meetings and conferences held between 1994 and 2009 and a database of reports, newspaper clippings and policy documentation. Findings When the policy process resulted in a concrete outcome there was always a clear recognition of the problem and policy alternatives, but success was more likely if there was an alignment of ,political' forces and/or when there was a determined bureaucracy. The impact of the other factors such as the media, community mobilization, non-governmental organizations (NGOs), the liquor industry and research are also discussed. Future avenues for policy research are identified, including the need for more systematic studies that give greater consideration to economic factors. Conclusions Alcohol policy development in South Africa takes place in a piecemeal fashion and is the product of various competing influences. Having a comprehensive national alcohol strategy cutting across different sectors may be a better way for other developing countries to proceed. [source]


Clinical Features and Prognosis of Nonepileptic Seizures in a Developing Country

EPILEPSIA, Issue 3 2001
W. Silva
Summary: ,Purpose: To determine the predictive value of clinical features and medical history in patients with nonepileptic seizures (NESs). Methods: One hundred sixty-one consecutive ictal video-EEGs were reviewed, and 17 patients with 41 NESs identified. NES diagnosis was defined as paroxysmal behavioral changes suggestive of epileptic seizures recorded during video-EEG without any electrographic ictal activity. Clinical features, age, sex, coexisting epilepsy, associated psychiatric disorder, social and economic factors, delay in reaching the diagnosis of NES, previous treatment, and correlation with outcome on follow-up were examined. Results: The study population included 70% female patients with a mean age of 33 years. Mean duration of NESs before diagnosis was 9 years. Forty-one percent had coexisting epilepsy. The most frequent NES clinical features were tonic,clonic mimicking movements and fear/anxiety/hyperventilation. The most common psychiatric diagnosis was conversion disorder and dependent and borderline personality disorder. Seventy-three percent of patients with pure NESs received antiepileptic drugs (AEDs), and 63.5% of this group received new AEDs. Fifty-nine percent of the patients received psychological/psychiatric therapy. At follow-up, 23.5% were free of NESs. Conclusions: All seizure-free patients had two good prognostic factors: having an independent lifestyle and the acceptance of the nonepileptic nature of the episodes. Video-EEG monitoring continues to be the diagnostic method to ensure accurate seizure classification. Establishing adequate health care programs to facilitate access to new technology in public hospitals as well as the implementation of continuous education programs for general practitioners and neurologists could eventually improve the diagnosis and treatment of patients with NESs.

Structure versus culture again: Corporatism and the ,new politics' in 16 Western European countries

EUROPEAN JOURNAL OF POLITICAL RESEARCH, Issue 5 2003
Bojan Todosijevi
This article analyzes the relationships between corporatism and ,new politics' using Siaroff's (1999) corporatism scores for 16 West European countries and data from Inglehart et al.'s (1998) World Value Survey. The results of the analysis show that corporatism is related to higher membership in peace movements and also to belief in the urgency of ecological problems. However, it is unrelated to postmaterialist values, votes for ,new parties', approval of the environmentalist and feminist movements, and willingness to contribute financially to environmental protection. The relationships between corporatism and ,new politics' is shown to be somewhat mediated by economic factors, while the hypothesis that postmaterialism is a principal factor behind the popularity of the new social movements is not substantiated.

IS TRUST A DRIVER FOR TERRITORIALLY EMBEDDED INDUSTRIAL SYSTEMS?

GEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 4 2007
A CASE STUDY OF THE HOME-BUILDING INDUSTRY IN NORWAY
ABSTRACT Trust is said to be necessary for creating and maintaining territorially embedded industrial systems. On the basis of data for the Norwegian home-building sector, this article analyses trust and price competition; how trust is built and dismantled; and trust and place. The main findings are that: trust and price competition interact, but trust is more important in the design and planning phases than in the construction phase; economic factors are important for building trust, together with competence and team work; and trust is related to space, partly through places embodied in trust and partly through trust embedded in places. However, this embeddedness is not like that which has long been claimed to exist in territorially embedded industrial systems, but embeddedness where trust acts as a reinforcement, contingent upon other factors, as a capacity restraint and a socially constructed need for face-to-face meetings.

Concepts in Social and Spatial Marginality

GEOGRAFISKA ANNALER SERIES B: HUMAN GEOGRAPHY, Issue 2 2000
Assefa Mehretu
The purpose of this paper is to present a conceptual taxonomy of marginality resulting from two counterposed structural conditions within laissez-faire on the one hand and controlled markets on the other. Marginality is a complex condition of disadvantage that individuals and communities may experience because of vulnerabilities which may arise from unequal or inequitable environmental, ethnic, cultural, social, political and economic factors. A typology of marginality is based on two primary and two derivative forms. The primary forms are contingent and systemic. The derivative forms are collateral and lever-aged. Contingent marginality is a condition that results from competitive inequality in which individuals and communities are put at a disadvantage because of the dynamics of the free market whose uncertain and stochastic outcomes affect them adversely. Systemic marginality is a socioeconomic condition of disadvantage created by socially constructed inequitable non-market forces of bias. Collateral marginality is a condition experienced by individuals or communities who are marginalized solely on the basis of their social and/or geographic proximity to individuals or communities that experience either contingent or systemic marginality. Lever-aged marginality is a contingent or systemic disadvantage that people/communities are made to experience when their bargaining position in free markets is weakened by dominant stakeholders like transnational corporations which are able to leverage lucrative concessions by using the threat of alternative, often cheaper and marginalized (contingent or systemic) labour pools to which they can potentially take their business.

Classification Analysis of World Economic Regions

GEOGRAPHICAL ANALYSIS, Issue 4 2001
Raymond J. Dezzani
Economic classifications of countries are of continuing utility for comparative and analytic purposes. However, traditional methods of arriving at classifications are often ad hoc, subjective, and imprecise, not permitting the assignments to be used for closer analysis. Discriminant analysis is used in this paper to isolate a time-specific set of economic factors delimiting economic state categories that correspond to core-periphery states. The core-periphery framework is shown to be a special case of a hierarchical market scheme. The purposes of this work are (1) to create a theoretically grounded, empirically derived classification over several time periods to permit dynamic comparisons to be made and provide an explanation of change in the global economy, and (2) to provide feedback information from the classification to supply the necessary rigor and quantitative insight to the world-systems theoretical framework. Results of the analysis suggest that different economic variables provide varying levels of explanation at different times. In particular, variables representing factor endowment provide a greater measure of explanation early in the sequence (for example, 1960) while trade and investment measures are of greater importance in the latter part of the study sequence (for example, 1990). OPEC countries significantly bifurcate the world-economy classification in 1970 and exhibit separate class characteristics. Even within the short time period, a number of countries are shown to transit among the classes. The model is also able to capture the dependence structure implicit in the world-systems framework.

Nutrient constraints to tropical agroecosystem productivity in long-term degrading soils

GLOBAL CHANGE BIOLOGY, Issue 12 2008
SOLOMON NGOZE
Abstract Soil degradation is one of the most serious threats to sustainable crop production in many tropical agroecosystems where extensification rather than intensification of agriculture has occurred. In the highlands of western Kenya, we investigated soil nitrogen (N) and phosphorus (P) constraints to maize productivity across a cultivation chronosequence in which land-use history ranged from recent conversion from primary forest to 100 years in continuous cropping. Nutrient treatments included a range of N and P fertilizer rates applied separately and in combination. Maize productivity without fertilizer was used as a proxy measure for indigenous soil fertility (ISF). Soil pools of mineral nitrogen, strongly bound P and plant-available P decreased by 82%, 31% and 36%, and P adsorption capacity increased by 51% after 100 years of continuous cultivation. For the long rainy season (LR), grain yield without fertilizer declined rapidly as cultivation age increased from 0 to 25 years and then gradually declined to a yield of 1.6 Mg ha,1, which was maintained as time under cultivation increased from 60 to 100 years. LR grain yield in the old conversions was only 24% of the average young conversion grain yield (6.4 Mg ha,1). Application of either N or P alone significantly increased grain yield in both the LR and short rainy (SR) seasons, but only application of 120 kg N ha,1 on the old conversion increased yield by >1 Mg ha,1. In both SR and LR, there was a greater average yield increment response to N and P when applied together (ranging from 1 to 3.8 Mg ha,1 for the LR), with the greatest responses on the old conversions. The benefit,cost ratio (BCR) for applying 120 kg N ha,1 alone was <1 except on the old conversions, while BCRs were>1 for applying 25 kg P ha,1 alone at all levels of conversion for both seasons. Application of both N (120 kg N ha,1) and P (25 kg P ha,1) on the old conversions resulted in the greatest BCRs. This study clearly indicates that maize productivity responses to N and P fertilizer are significantly affected by the age of cultivation and its influence on ISF, but that loss of productivity can be restored rapidly when these limiting nutrients are applied. Management strategies should consider ISF and economic factors to determine optimal N and P input requirements for achieving and sustaining profitable crop production on degraded soils. [source]


A Method for Predicting Chloride Concentrations in Leachate at Natural Attenuation Landfills in the Precambrian Shield Regions of Ontario, Canada

GROUND WATER MONITORING & REMEDIATION, Issue 3 2000
Jim Gehrels
Natural attenuation landfill sites continue to be the preferred method of domestic waste disposal in the Precambrian Shield regions of Ontario due to economic factors. The main challenge in siting these landfills is ensuring that there will be no adverse impact on off-site water resources. Impact risk assessments are generally based on estimated volumes and strengths of chloride in the leachate. While volumes can be estimated using simple water balances, peak chloride concentration predictions are based on judgment and are quite variable. Since design chloride strengths dictate the size of the required attenuation zone, overestimating concentrations will typically make it impossible to find a suitable site, while underestimating concentrations increases the potential for adverse off-site impacts occurring. Hydrogeological data from active and closed landfills in the Precambrian Shield region were collected to help develop a reliable method of predicting peak chloride concentrations in leachate. This study focused on 21 sites located on relatively permeable sandy soils since landfills underlain by low permeability clayey soils retain leachate similar to lined facilities. Linear regression analyses were conducted to determine if source chloride concentrations at the "sand" sites are significantly influenced by waste thickness, fill area, waste volume, waste deposition rate, hydraulic conductivity, upgradient flow length, depth to the water table, and moisture surplus. A strong relationship (R = 0.957) was found to exist between source chloride concentrations and waste volume. This empirical volume versus chloride regression equation can be used as the basis for establishing design chloride concentrations at new natural attenuation landfills developed over sandy soils in the Precambrian Shield regions of Ontario. An alternative risk assessment approach is required for sites developed over clay soils. [source]


The impact of health on individual retirement plans: self-reported versus diagnostic measures

HEALTH ECONOMICS, Issue 7 2010
Nabanita Datta Gupta
Abstract We reassess the impact of health on retirement plans of older workers using a unique survey-register match-up which allows comparing the retirement effects of potentially biased survey self-reports of health to those of unbiased register-based diagnostic measures. The aim is to investigate whether even for narrowly defined health measures a divergence exists in the impacts of health on retirement between self-reported health and objective physician-reported health. Our sample consists of older workers and retirees drawn from a Danish panel survey from 1997 and 2002, merged to longitudinal register data. Estimation of measurement error-reduced and selection-corrected pooled OLS and fixed effects models of retirement show that receiving a medical diagnosis is an important determinant of retirement planning for both men and women, in fact more important than economic factors. The type of diagnosis matters, however. For men, the largest reduction in planned retirement age occurs for a diagnosis of lung disease while for women it occurs for musculo-skeletal disease. Except for cardiovascular disease, diagnosed disease is more influential in men's retirement planning than in women's. Our study provides evidence that men's self-report of myalgia and back problems and women's self-report of osteoarthritis possibly yield biased estimates of the impact on planned retirement age, and that this bias ranges between 1.5 and 2 years, suggesting that users of survey data should be wary of applying self-reports of health conditions with diffuse symptoms to the study of labor market outcomes. On the other hand, self-reported cardiovascular disease such as high blood pressure does not appear to bias the estimated impact on planned retirement. Copyright © 2009 John Wiley & Sons, Ltd.

Takeover activity in Australia: endogenous and exogenous influences

ACCOUNTING & FINANCE, Issue 3 2005
Frank Finn
G34 Abstract The present paper analyses the population of takeover bids for listed Australian companies using quarterly data over a 25-year period to re-examine the predictability of takeover activity and to determine if there is a flow on impact on macroeconomic variables. We examine whether takeover activity: (i) is endogenous; that is, determined by own activity; (ii) is jointly determined by macroeconomic and capital market variables; and (iii) has an exogenous spillover impact across the economy. We find that stock prices and takeover activity share a long-term common trend, the relative success of takeover bids is independent of sharemarket activity, and conclude that aggregate takeover activity is driven by fundamental economic factors rather than by speculative activity.

Application of multicriteria decision analysis in environmental decision making

INTEGRATED ENVIRONMENTAL ASSESSMENT AND MANAGEMENT, Issue 2 2005
Gregory A. Kiker
Abstract Decision making in environmental projects can be complex and seemingly intractable, principally because of the inherent trade-offs between sociopolitical, environmental, ecological, and economic factors. The selection of appropriate remedial and abatement strategies for contaminated sites, land use planning, and regulatory processes often involves multiple additional criteria such as the distribution of costs and benefits, environmental impacts for different populations, safety, ecological risk, or human values. Some of these criteria cannot be easily condensed into a monetary value, partly because environmental concerns often involve ethical and moral principles that may not be related to any economic use or value. Furthermore, even if it were possible to aggregate multiple criteria rankings into a common unit, this approach would not always be desirable because the ability to track conflicting stakeholder preferences may be lost in the process. Consequently, selecting from among many different alternatives often involves making trade-offs that fail to satisfy 1 or more stakeholder groups. Nevertheless, considerable research in the area of multicriteria decision analysis (MCDA) has made available practical methods for applying scientific decision theoretical approaches to complex multicriteria problems. This paper presents a review of the available literature and provides recommendations for applying MCDA techniques in environmental projects. A generalized framework for decision analysis is proposed to highlight the fundamental ingredients for more structured and tractable environmental decision making. [source]


Consumer morality in times of economic hardship: evidence from the European Social Survey

INTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 2 2010
*Article first published online: 1 FEB 2010, Clįudia Abreu Lopes
Abstract Crimes of everyday life, often referred to as unfair or unethical practices committed in the marketplace by those who see themselves and are seen as respectable citizens, have burgeoned as a result of the transformations in the European economy in the late 20th century, namely the transition to neo-liberal markets and the emergence of consumer society. A ,cornucopia of new criminal opportunities' has given rise to a new range of crimes such as ripping software, making false insurance claims or paying cash on hand to circumvent taxes. These shady behaviours (legal or not) are part of people's experience, albeit they are collectively regarded as morally dubious. Taken collectively, crimes of everyday life are indicators of the moral stage of a particular society and therefore a valuable instrument for social and political analysis. This paper addresses the question of whether and under which conditions feelings of economic hardship trigger crimes of everyday life. A multilevel theoretical and empirical perspective that integrates theories stemming from political science, sociology, and social psychology is adopted. I start by exploring the embeddedness of economic morality in social institutions, followed by an elaboration of the concept of market anomie to account for deviant behaviour in the marketplace, to finally step down to the examination of the correspondence between social attitudes and consumer behaviour, as postulated by the Theory of Planned Behaviour. The empirical study relies on micro data from the European Social Survey (ESS) (Round 2) and attempts to model, for each country, a formative measure of crimes of everyday life based on socio-demographic variables and the current economic situation, as it is perceived by the individual (taken as a measure of relative deprivation). The resultant country-specific regression coefficients are mapped onto the broader economic and normative context of 23 European countries. The results reveal that crimes of everyday life are driven by feelings of economic hardship only in countries where normative factors dictate their deviance. In countries where fraudulent behaviour is more generalized, inner motivations to offend play a secondary role as the more privileged consumers are more likely to commit fraud as they interact more often with the market. In turn, normative aspects result from a dynamic interplay of cultural and economic factors. As the economy grows faster, the tendency to offend in the market becomes more visible, but only in countries whose gross domestic product (GDP) stands above the European average. In countries with low GDP, the normative landscape is shaped by cultural factors that seem to obfuscate the power of economic factors favourable to consumer fraud. [source]


A comprehensive techno-economic analysis method for power generation systems with CO2 capture

INTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 4 2010
Gang Xu
Abstract A new comprehensive techno-economic analysis method for power generation systems with CO2 capture is proposed in this paper. The correlative relationship between the efficiency penalty, investment increment, and CO2 avoidance cost is established. Through theoretical derivation, typical system analysis, and variation trends investigation, the mutual influence between technical and economic factors and their impacts on the CO2 avoidance cost are studied. At the same time, the important role that system integration plays in CO2 avoidance is investigated based on the analysis of a novel partial gasification CO2 recovery system. The results reveal that for the power generation systems with CO2 capture, the efficiency penalty not only affects the costs on fuel, but the incremental investment cost for CO2 capture (U.S.$,kW,1) as well. Consequently, it will have a decisive impact on the CO2 avoidance cost. Therefore, the added attention should be paid to improve the technical performance in order to reduce the efficiency penalty in energy system with CO2 capture and storage. Additionally, the system integration may not only decrease the efficiency penalty, but also simplify the system structure and keep the investment increment at a low level, and thereby it reduces the CO2 avoidance cost significantly. For example, for the novel partial gasification CO2 recovery system, owing to system integration, its efficiency can reach 42.2%, with 70% of CO2 capture, and its investment cost is only 87$,kW,1 higher than that of the reference IGCC system, thereby the CO2 avoidance cost is only 6.23$,t,1 CO2. The obtained results provide a comprehensive technical,economical analysis method for energy systems with CO2 capture useful for reducing the avoidance costs. Copyright © 2009 John Wiley & Sons, Ltd.

Macroeconomic factors and share returns: an analysis using emerging market data

INTERNATIONAL JOURNAL OF FINANCE & ECONOMICS, Issue 1 2002
S.G.M. Fifield
Abstract This paper investigates the extent to which global and local economic factors explain returns in emerging stock markets (ESMs). The economic factors are determined using principal components analysis. The results suggest that the local economic variables included in this study can be summarized by GDP, inflation, money and interest rates, while the selected global variables can be sufficiently characterized by world industrial production and world inflation. These components are then used as inputs into a regression analysis in order to explain the index returns of 13 ESMs over the period 1987,96. The analysis indicates that while world factors are significant in explaining ESM returns, local factors may also play a crucial role. Copyright © 2002 John Wiley & Sons, Ltd. [source]


Management of systemic lupus erythematosus in the coming decade: potentials and challenges

INTERNATIONAL JOURNAL OF RHEUMATIC DISEASES, Issue 4 2006
Hiok Hee CHNG
Abstract The management of systemic lupus erythematosus (SLE) has improved in the past 50 years, but there is still a 3,5-fold increased mortality compared to the general population, with major organ failure due to active disease, infection and cardiovascular disease as the major challenges for the coming decade. Research advances at cellular, molecular and genetic levels enhance our understanding of the immunopathogenic mechanisms of SLE, leading to the development of drugs targeting specific sites of immune dysregulation , with therapies directed at cytokines, B- and T-cells, and their interactions showing promise. Advances are expected in the field of haematopoietic stem cell transplant (HSCT) as a therapeutic option for a subset of patients. Furthermore, some non-traditional immunomodulating therapies like statins, leflunomide and tacrolimus may prove useful as alternative or adjunct treatment in some patients. A better understanding of how current immunosuppressants act at the cellular and molecular level should guide the re-evaluation of the indications, doses and duration of therapy in clinical trials using these agents, many of which have not been subjected to proper double-blinded placebo-controlled studies. Research on triggers of SLE onset and flare of activity continues to yield information helpful in prevention. The evidence on the impact of psychosocial and economic factors on the outcome of SLE is overwhelming and the rheumatology community should enlist the assistance of other healthcare professionals, patient advocates and local health authorities to address these issues pertinent to good patient care and outcome.

The state of worker protections in the United States: Unregulated work in New York City

INTERNATIONAL LABOUR REVIEW, Issue 2-3 2008
Annette BERNHARDT
Abstract. Using original data gathered in 2003,06, the authors examine the prevalence and types of non-compliance with labour law in New York City. Workplace violations , or "unregulated work", are widespread across a range of low-wage industries and have been driven by a mix of economic factors as well as public policy. The solution, the authors argue, is to strengthen law enforcement and provide for the new types of employment relationship that have resulted from changes in the organization of work and production.

Migration and Policies in the European Union: Highly Skilled Mobility, Free Movement of Labour and Recognition of Diplomas

INTERNATIONAL MIGRATION, Issue 1 2001
Joćo Peixoto
This article evaluates the relationship between highly skilled mobility (especially by individuals with university-level degrees) and migration policies. Data from the European Union (EU) and Portugal (in particular) provide the empirical basis of the research. EU policies regarding the free circulation of individuals which aim to build the "common market" for economic factors (including labour) are reviewed, as are the more specific recognition of diplomas policies for professional and academic purposes, and recent levels of international mobility in both the EU and Portugal. The article also enumerates the main obstacles that, from a political and legal or social and cultural perspective, explain the low mobility revealed by those figures. Obstacles include the broad denial of citizenship rights; the necessity of assuring a means of sustenance; linguistic and technical exigencies for diploma recognition; the social attributes of work (more explicit in the service sector); and the institutional nature of national skilled labour markets. The main exception to the low mobility rule , movements of cadres in the internal labour markets of transnational corporations , together with flows in other multinational organizations, are also reviewed. In these, migrations are relatively exempt from political constraints and, significantly, avoid the recognition procedures adopted by the EU. In other words, it seems that the entry of highly skilled individuals in a transnational corporation, and not their citizenship in a Europe without frontiers, is what enables them to achieve effective mobility.

Two Logics of Labor Organizing in the Global Apparel Industry

INTERNATIONAL STUDIES QUARTERLY, Issue 3 2009
Mark Anner
What factors account for labor strategies in global industries? While some scholars point to economic factors and others look to political opportunity structures, an examination of union actions in the Central American apparel export industry over a 14-year period suggests that activists' historical experiences and ideological orientations also strongly influence union dynamics. Left-oriented unions tend to form unions through transnational activism whereas conservative unions most often turn to plant-level cross-class collaboration. Moreover, these two union strategies are interconnected. Successful transnational activism facilitates conservative union formation through a "radical flank" mechanism; the threat of left-union organizing motivates employers to accept unionization by conservative unions to block left unions from gaining influence in the plant. To examine these arguments, this article employs pooled time-series statistical analysis, structured interviews with labor organizers, and process tracing that draws on nine months of field research in Honduras and El Salvador.

The role of zoos in biosurveillance

INTERNATIONAL ZOO YEARBOOK, Issue 1 2007

Zoos are ideally placed to act as epidemiological monitoring stations because for decades, many have been building up detailed collections of serum banks, tissue banks and medical record-keeping systems that could be mined for information that would be beneficial to public health. For example, in 1999 wild Crows Corvus brachyrhynchos in the United States of America started to die of unknown causes but it was not until some died in the grounds of a zoological institution that West Nile virus, which is a threat to both human and animal health, was identified. There is a serious disparity in the type and amount of biosurveillance provided for humans, agricultural livestock and wildlife agencies, often driven by economic factors. There is an argument for public-health entities to contribute funds to the cost of managing serum-banks and testing stations within zoos to enhance biosurveillance in urban settings, in a cost-effective and mutually beneficial manner. The key to sustainable and integrated biosurveillance lies in public-health professionals working with zoo professionals, who care for wild animals on a day-to-day basis, to create electronic surveillance networks. This could be of utmost benefit to everyone. [source]


Economic determinants of biodiversity change over a 400-year period in the Scottish uplands

JOURNAL OF APPLIED ECOLOGY, Issue 6 2008
Nick Hanley
Summary 1Economic forces are recognized as an important driving factor behind current biodiversity losses. This study investigates whether such factors have been important in determining one measure of biodiversity change over the ,long run', in our case, 400 years , for upland sites in Scotland. 2A combination of palaeoecological, historical and economic methods is used to construct and then analyse a database of factors contributing to changes in plant diversity over time for 11 upland sites. 3Using an instrumental variables panel model, we find livestock prices, our proxy for grazing pressure, to be a statistically significant determinant of diversity change, with higher grazing pressures resulting in lower diversity values on average, although site abandonment is also found to result in a fall in plant diversity. Technological change, such as the introduction of new animal breeds, was not found to be a statistically significant determinant. 4Using later period data (post 1860) on livestock numbers at the parish (local) level, we were able to confirm the main result noted above (3) in terms of the effects of higher grazing pressures on plant diversity. 5Synthesis and applications. This study shows how data from very different disciplines can be combined to address questions relevant to contemporary conservation and understanding. This novel, interdisciplinary approach provides new insights into the role of economic factors as a driver of biodiversity loss in the uplands. Biodiversity levels have varied considerably over 400 years, partly as a function of land management, suggesting that establishing baselines or ,natural' target levels for biodiversity is likely to be problematic. Changes in livestock grazing pressures brought about by changes in prices had statistically significant effects on estimated plant diversity, as did land abandonment. This suggests that long-term management of upland areas for the conservation of diversity should focus on grazing pressures as a key policy attribute. Another policy implication is that drastic cuts in grazing pressures , such as might occur under current reforms of the Common Agricultural Policy , can have adverse biodiversity consequences.

Voluntary Appointment of Independent Directors in Taiwan: Motives and Consequences

JOURNAL OF BUSINESS FINANCE & ACCOUNTING, Issue 9-10 2008
Chaur-Shiuh Young
Abstract:, This study explores factors that motivate firms to increase board independence in the absence of legal requirements to do so. In addition, we examine the impact of voluntary enhancement of board independence on firm performance. Using a sample of listed companies in Taiwan, we show that voluntary appointment of independent directors is associated with both economic factors and managerial power. Specifically, we find that board independence increases with the weaknesses of alternative corporate governance mechanisms and the severity of agency problems. However, board independence decreases with managerial ownership and family control. In addition, by employing a simultaneous equations model with selectivity, we provide evidence supporting the positive performance impact of voluntary appointment of independent directors in Taiwan.

Drivers of ecosystem change and their impacts on human well-being in Lake Victoria basin

AFRICAN JOURNAL OF ECOLOGY, Issue 2009
Eric O. Odada
Abstract To offer an increased understanding of the spatial patterns, temporal, social and physical predictors of the conversion and transformations of land use in Lake Victoria basin, an assessment of proximate and underlying forces is presented. This study discusses key theoretical underpinnings for the manifold linkages existing between selected drivers of land-use changes around the basin and their consequences on human well-being. Using a meta-analytical research design, the paper analyses ecosystems level cases of the causes of land use and cover changes in the basin, to determine any spatio-temporal or institutional patterns and dynamics. A suite of recurrent core variables has been identified to influence land use and cover changes in the basin. The most prominent of these at the underlying category are climatic factors, economic factors, institutions, national and regional policies, population growth and other remote influences. At the proximate level, these factors drive cropland expansion, overgrazing, infrastructure extension and rates of land degradation. These are supported by empirical evidence from the basin. This assessment is crucial for appropriate local and transboundary policy interventions, which have to be fine-tuned to the locale-specific dynamic patterns associated with the inherent ecosystems changes.

Social capital, age and religiosity in people who are lonely

JOURNAL OF CLINICAL NURSING, Issue 3 2006
William Lauder PhD
Aims and objectives., The aims of the study were to (i) investigate age and loneliness, (ii) investigate the association between religiosity and loneliness, and (iii) and explore the relationship between social capital and loneliness. Background., Loneliness is the subjective experience of social isolation and is a risk factor for a wide range of health problems including heart disease and depression. Poor self-rated health, domestic violence and poor economic conditions are associated with greater loneliness. Design., The study was a cross-sectional survey of a random sample of adults aged 18 years and over. Methods., A random sample of 1289 subjects was interviewed by computer-assisted telephone interviewing. This interview included the Loneliness Scale and items from the Social Capital Module of the General Household Survey. Findings., Loneliness is more common in men and people without strong religious beliefs. An income-loneliness gradient is evident. Little support was found for the association between social capital and loneliness. Conclusion., The prevalence of loneliness is relatively stable in this population. Loneliness is linked to income and unemployment and as such pathways between socio-economic factors, loneliness and health need to guide interventions and future research. Relevance to clinical practice., Loneliness is linked to a range of social and economic factors. Current Health Visiting practice recognizes the importance of tackling the effects of poverty and social deprivation and places community building at the core of much Health Visiting practice. This broad community level approach can usefully transfer into all community nursing and health promotion activity. [source]


Homelessness in the US and Germany: a cross-national analysis,

JOURNAL OF COMMUNITY & APPLIED SOCIAL PSYCHOLOGY, Issue 3 2003
Carolyn J. Tompsett
Abstract A public opinion survey was administered by telephone to nationally representative samples in the US and Germany to assess prevalence of homelessness as well as attitudes, opinions and knowledge regarding homelessness. Lower prevalence rates were found in Germany as compared with the US. German respondents demonstrated higher levels of general compassion, greater support for the public rights of the homeless, a greater tendency to view the homeless as trustworthy, and were more likely to view economic factors and less likely to view personal failings as integral to the problem of homelessness. Respondent age, gender, and political affiliation predicted many public opinion variables. Copyright © 2003 John Wiley & Sons, Ltd. [source]


The components of resilience,Perceptions of an Australian rural community,

JOURNAL OF COMMUNITY PSYCHOLOGY, Issue 8 2010
Elizabeth Buikstra
Resilience, of individuals, is a well-established concept in the psychology/mental health literatures, but has been little explored in relation to communities. Related theory in the community development and social impact assessment literature provides insight into qualities and assets of communities that enable them to develop effectively or to adapt to major changes. This article reports the components of community and individual resilience identified through a participatory action research study within a rural Australian community. These are social networks and support; positive outlook; learning; early experiences; environment and lifestyle; infrastructure and support services; sense of purpose; diverse and innovative economy; embracing differences; beliefs; and leadership. These components entail interactions between individuals, the community, infrastructure, the environment and the economy in the process of building resilience. The findings extend from previous research by recognizing environmental and economic factors, infrastructure and support services, as enhancing resilience, and expand the limited evidence base for those wishing to promote resilience at the community scale. © 2010 Wiley Periodicals, Inc.

Residential Design Implications of Consumers' Recycling Behaviors

JOURNAL OF INTERIOR DESIGN, Issue 1-2 2003
Sharon Macy M.A.
ABSTRACT Each year landfills receive a growing amount of waste that could be eliminated by recycling practices supported through the design of kitchens. This study had three objectives: (a) to examine residential design implications for incorporating recycling within the home, (b) to examine consumer's feelings of environmental altruism and their behaviors toward recycling within the context of situational conditions within the home, and (c) to examine consumer's views regarding the convenience of their home's recycling facilities. The primary research instrument was a survey of consumer behaviors and attitudes toward recycling. Certified Kitchen Designers provided client names for whom they had designed a kitchen as part of a remodel or new home construction within the last five years. Questionnaires were mailed to 271 households with a 58.2% response rate achieved. Five areas of information were addressed in the survey: sociode-mographics, behaviors and situational design factors, altruistic values, perceived inconvenience, and economic factors. Descriptive and inferential statistics were used for analysis with Chi-square tests used to examine relationships between variables. Results support including an area for recycling in the kitchen or a space that is directly adjacent such as an attached garage; convenience was found to be a primary factor in the recycling behaviors of highly altruistic individuals. It is important to design an environment that supports recycling. Whether recycling is convenient or not will have an influence on an individual's recycling behaviors. With environments that support recycling behaviors, consumers will increase their quantity and accuracy in recycling, which in turn could lead to an increase in attitudes toward other pro-environmental actions.
