Empirical Findings (empirical + finding)
Selected AbstractsThe Role and Functions of Audit Committees in the Indian Corporate Governance: Empirical FindingsINTERNATIONAL JOURNAL OF AUDITING, Issue 1 2004Jawaher Al-Mudhaki This paper examines the composition, focus and functions of audit committees (ACs), the effects of meetings and the criteria used in the selection of members by Indian listed companies from 73 questionnaire responses. The survey was carried out during February,March, 2002. The study reveals that so far only 56.2% of companies have established an AC despite the fact that it is now mandatory. Of those companies which have ACs, 68.3% have between three and six members on ACs. However, only 14.6% of companies have independent non-executive directors on the committee, while 90.2% have non-executive directors. This shows a lack of independent representation on the committees. The functions of ACs are quite diverse and are classified in three areas: financial statements and reporting, audit planning, and internal control and evaluation. The review of annual audited financial statements, discussion and recommendations of audit fees and review of the effectiveness of internal control were rated very highly by the respondents. The review of note disclosure and scope of external audit work are other important functions performed by ACs. The most important areas for focus are compliance with the standards and regulatory bodies, probing material items and undisclosed liabilities. However, there are statistical differences between medium and large sized companies in the performance of their role. The main criteria used for membership of an AC are: experience and knowledge of business, experience of holding similar positions and accounting and finance expertise. Ownership in the company was not perceived as an important criterion. The majority of companies' AC meetings are held monthly or quarterly. MANOVA analysis reveals that the frequency of AC meetings has an effect on the internal control functions. The study concludes that the concept of an AC is not new in India but their formation is slow and their composition lacks independence. AC functions are still concentrated in the traditional areas of accounting and their role is not changing fast enough to make the corporate governance more effective. [source] Ethical Attitudes in Small Businesses and Large Corporations: Theory and Empirical Findings from a Tracking Study Spanning Three DecadesJOURNAL OF SMALL BUSINESS MANAGEMENT, Issue 2 2006Justin G. Longenecker This study offers a theoretical framework of ethical behavior and a comparative analysis of ethical perceptions of managers of large, mostly publicly traded corporations (those with 1,000 or more employees) and the owners and managers of smaller companies (those with fewer than 100 employees) across 17 years. The primary research provides basic data on the changing standards of ethics as perceived by leaders of large and small businesses where the cultures frequently fall into sharp contrast. Our findings reveal the extent to which the message of business integrity is gaining or losing ground within large and small companies. It does this by means of respondents' judgments of acceptable responses to 16 scenarios profiling common business situations with questionable ethical dimensions. Based on responses from over 5,000 managers and employees (from firms of all sizes) to our scenarios at three points in time (1985, 1993, 2001), we tested two research questions. First, for firms of all sizes, have business ethics improved or declined between the years 1985 and 2001? Second, comparing responses of large and small firm executives across the 1985,2001 time frame, is there a discernible difference in their ethical standards? Our results suggest that business leaders are making somewhat more ethical decisions in recent years. We also found that small business owner,managers offered less ethical responses to scenarios in 1993 but that no significant differences existed with large firm managers in 1985 and 2001. Implications of our findings are discussed. [source] The Italian experience in social reporting: an empirical analysisCORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 3 2006Davide Secchi Abstract This analysis tries to discover an empirical validation to back up the hypothesis that the Italian phenomenon of social reporting has changed with regard to the past and is growing in importance. After considering the evolution of Italian literature on the issue, the paper tries to find connections between this literature and social reporting practices. Empirical findings are based on 62 Italian social reports. The paper tries to answer three questions: (a) what kind of organization publishes social reports; (b) what are the main differences, if any, between different reports belonging to diverse organizations; (c) which are the leading models. Social reports have been sorted according to three main issues: report objectives, emerging models and stakeholder mapping. Collected data suggest that there is a common ground for organizations in socially responsible behaviour, but also that this common ground fits the need of every single organization.

Stress interacts with these factors and increases addiction vulnerability and relapse risk, thereby playing a significant role in the course of the illness. This paper reviews our efforts in developing and validating laboratory models of stress and drug cue-related provocation to assess stress responses and stress-related adaptation in addicted individuals compared with healthy controls. Empirical findings from human laboratory and brain imaging studies are presented to show the specific stress-related dysregulation that accompanies the drug-craving state in addicted individuals. In order to adequately validate our laboratory model, we have also carefully examined relapse susceptibility in the addicted individuals and these data are reviewed. The overarching goal of these efforts is to develop a valid laboratory model to identify the stress-related pathophysiology in addiction with specific regard to persistent craving and compulsive seeking. Finally, the significant implications of these findings for the development of novel treatment interventions that target stress processes and drug craving to improve addiction relapse outcomes are discussed. [source] Growth of Creative Occupations in U.S. Metropolitan Areas: A Shift-Share AnalysisGROWTH AND CHANGE, Issue 3 2006TODD M. GABE ABSTRACT This article uses a shift-share model to investigate the growth of creative occupations in U.S. metropolitan areas during the 1990s. Empirical findings indicate that the performance of the creative economy varied widely across the U.S., and that the highest competitive growth rates of the creative workforce occurred in the Rocky Mountain, Southeast, and Southwest regions. Further analysis focused on whether high competitive workforce growth between 1990 and 2000 translated into high competitive employment growth from 1999 to 2003. The results show that many of the areas with the highest competitive growth rates of creative economy employment from 1999 to 2003 were some of the weakest regions in terms of creative workforce growth during the 1990s. This raises questions about the extent to which jobs follow people in the creative economy, and suggests that an initial strong presence in the creative economy is not a prerequisite for future growth. [source] Local Industry Agglomeration and New Business ActivityGROWTH AND CHANGE, Issue 1 2003Todd Gabe New businesses are highly involved in innovative activity, which enhances worker productivity and leads to increased economic output. This paper investigates the effects of industry concentration on the incidence of new business openings in the 5,504 Maine county-industries. Empirical findings indicate that new business activity increases with the number of incumbent establishments in a county-industry and its concentration level relative to the U.S. economy. Model simulations show that raising county-industries, with no initial industry presence, to concentration levels similar to that of the industry in the U.S. economy results in a 1.7 to 8.9 percent increase in the expected number of business openings over a three-year period. Empirical results also suggest that industry clusters comprised of young and small establishments are more conducive to new business formation than clusters made up of mature and large companies. [source] THE ECONOMIC IMPACTS OF VOLUNTARY ENVIRONMENTAL PERFORMANCE OF FIRMS: A CRITICAL REVIEWJOURNAL OF ECONOMIC SURVEYS, Issue 3 2009Esther Blanco Abstract New trends in studies on the governance of natural assets include substantial consideration of the role of voluntary initiatives. A traditional economic view states that there is a trade-off between being green and being competitive. According to that view, no voluntary environmental action is expected to occur. To undertake an in-depth analysis of the scope for voluntary action, this paper reviews empirical literature that analyzes the relationship between manufacturing firms' environmental initiatives or performance and economic results. This review moves beyond the general test of the ,pay to be green' hypothesis, preferring instead to systematize empirical results in more specific research questions. Empirical findings of the reviewed literature generally support that there is no penalty for being green. In addition, the typology of firms, the methods utilized for implementing environmental initiatives, the intensity of abatement efforts and stockholders' valuation of green firms have all been shown to have a sizeable influence on the actual economic results of environmental action or management. Consequently, the findings of this paper challenge the traditional strategic theory that predicts widespread free-riding; it holds major implications for environmental policy-making and environmental business decisions. [source] The Effect of State Economic Development Incentives on Employment Growth of EstablishmentsJOURNAL OF REGIONAL SCIENCE, Issue 4 2002Todd M. Gabe This paper examines the effects of state economic development incentives on the growth of 366 Ohio manufacturing and nonmanufacturing establishments that launched major expansions between 1993 and 1995. Growth is measured as the actual employment change that occurred in these establishments and as the employment growth announced when expansions were launched. Empirical findings indicate that incentives have very little (or even a negative) effect on actual growth and they have a substantial positive effect on announced growth. Findings also suggest that establishments that received incentives overestimated their announced employment targets more than establishments that did not receive incentives. [source] Minority Business Access to Mainstream MarketsJOURNAL OF URBAN AFFAIRS, Issue 1 2001Timothy Bates As minority-owned firms have penetrated the broader national marketplace,selling goods and services to corporate as well as government clients,the issue of capacity has surfaced. Particularly in government markets, one claim is that minority business enterprises (MBEs) are smaller, younger firms than nonminorities, and hence they often lack the capacity to compete effectively for government contracts. Affirmative action procurement programs, in this view, provide preferential treatment for less qualified businesses, generating reverse discrimination against the dominant, typically white-male group of business owners. A counterclaim, put forth by proponents of preferential procurement programs, is that discriminatory barriers such as entrenched old-boy networks impede MBE expansion into mainstream markets. Do the entrenched networks really thwart MBEs, or do they simply lack the capacity to compete? Empirical findings of this study support the discriminatory barrier explanation. [source] Proxy contest, board reelection, and managerial turnover,yes, the proxy contest outcome matters,MANAGERIAL AND DECISION ECONOMICS, Issue 1 2005Gili Yen In a previous study based on a matched sample analysis, it is found that in Taiwan top management turnover rate for the listed firms in the presence of a proxy contest is much higher than the ones without a proxy contest. In other words, the hypothesis of job security has gained empirical support. Taking account of the proxy contest outcomes, the present study extends the sample years, i.e. 1994,1999, to further examine the impact of proxy contest on managerial turnover. In conformity with expectations, the major empirical findings can be summarized as follows: the highest turnover rate of top management is observed in the firms of which the dissidents win majority seats; the second highest turnover rate is observed in the firms of which the dissidents win some seats; whereas the lowest turnover rate is observed in the firms of which the dissidents win no seats. Empirical findings of this kind provide further support to the view that proxy contest has played an effective monitoring role in disciplining incumbent management.

[source] The front end of innovation in an era of industry convergence: evidence from nutraceuticals and functional foodsR & D MANAGEMENT, Issue 5 2006Stefanie Bröring Industry convergence, defined as a ,blurring' of boundaries between industries, induced by converging value propositions, technologies and markets, appears to be a pervasive phenomenon leading to the emergence of inter-industry segments. A current example of convergence can be witnessed in the nutraceuticals and functional foods sector, emerging at the boundary between the food and pharmaceutical industries. Not only technologies blur, but there is also a convergence of demand structures: consumers try to satisfy different needs in one transaction. In this context, this paper explores how actors from different industry-specific resource backgrounds can engage in an innovative activity requiring new technological and marketing competences. Given that absorptive capacity is limited by existing competences, this paper asks how organizations with different R&D competences are able to seize opportunities for innovation emerging from convergence. Empirical findings based on primary data collected from 54 R&D projects of a nutraceutical cluster show that there are different approaches of front end decision making: while some firms follow existing processes for front end decision making, others leave existing paths and need partners to fill in gaps already identified at the front end of innovation. [source] Societal and Individual Determinants of Medical Care Utilization in the United StatesTHE MILBANK QUARTERLY, Issue 4 2005RONALD ANDERSEN A theoretical framework for viewing health services utilization is presented, emphasizing the importance of the (1) characteristics of the health services delivery system, (2) changes in medical technology and social norms relating to the definition and treatment of illness, and (3) individual determinants of utilization. These three factors are specified within the context of their impact on the health care system. Empirical findings are discussed which demonstrate how the framework might be employed to explain some key patterns and trends in utilization. In addition, a method is suggested for evaluating the utility of various individual determinants of health services utilization used in the framework for achieving a situation of equitable distribution of health services in the United States. [source] Performance Decline and Turnaround in Public Organizations: A Theoretical and Empirical Analysis,BRITISH JOURNAL OF MANAGEMENT, Issue 3 2005Pauline Jas Public sector performance is currently a significant issue for management practice and policy, and especially the turnaround of those organizations delivering less than acceptable results. Theories of organizational failure and turnaround derive largely from the business sector and require adaptation to the public service. The performance of public organizations is more complex to measure, is related to institutional norms, and the idea of ,failure' is problematic. Empirical findings from a real-time, longitudinal study of poorly performing English local authorities are used to develop an initial theory of performance failure and turnaround suited to public organizations. The paper argues that the typical performance of public organizations over time is cyclical. Where cognition and leadership capability are absent, organizations fail to self-initiate turnaround. In this situation authoritative external intervention is necessary. The strategies applied are principally concerned with building a leadership capability that engages senior politicians and managers in order to overcome inertia and collective action problems. The theory is presented in the form of seven propositions that provide a basis for further research across the public sector. [source] Pricing Behavior and the Response of Hours to Productivity ShocksJOURNAL OF MONEY, CREDIT AND BANKING, Issue 7 2007DOMENICO J. MARCHETTI pricing behavior; technology shocks; hours Recent contributions have suggested that technology shocks have a negative impact on hours, contrary to the prediction of standard flexible-price models of the business cycle. Some authors have interpreted this finding as evidence in favor of sticky-price models, while others have either extended flexible-price models or disputed the empirical finding itself. In this paper, we estimate a variety of alternative total factor productivity measures for a representative sample of Italian manufacturing firms and on average find a negative effect of productivity shocks on hours growth. More interestingly, using the reported frequency of price reviews, we show that the contractionary effect is stronger for firms with stickier prices and weaker or not significant for firms with more flexible prices. Price stickiness remains a crucial factor in shaping the response of hours after controlling for product storability or market power. [source] An Empirical Analysis of the Effects of Increasing Deductibles on Moral HazardJOURNAL OF RISK AND INSURANCE, Issue 3 2008Jennifer L. Wang Using information on timing and number of claims in a unique data set pertaining to comprehensive automobile insurance with the increasing deductible provision in Taiwan, the authors provide new evidence for moral hazard. Time-varying correlations between the choice of the insurance coverage and claim occurrence are significantly positive and exhibit a smirk pattern across policy months. This empirical finding supports the existence of asymmetric information. A subsample estimation depicts insured drivers' significant responses to increasing deductibles, which implies the existence of moral hazard. According to the probit regression results, the increasing deductible makes policyholders who have ever filed claims less likely to file additional claims later in the policy year. The empirical findings strongly support the notion that the increasing deductible provision helps control moral hazard. [source] A Model of Spoils PoliticsAMERICAN JOURNAL OF POLITICAL SCIENCE, Issue 1 2009Ernesto Dal Bó Accounts of state failure in the developing world frequently highlight a logic of "spoils politics" in which a government and an opposing faction vie for control of the state and the accompanying spoils. Attempts to buy the opposition off play a key role in this logic, and an informational problem often complicates these efforts. Because of limited transparancy, the government generally has a better idea about the actual size of the spoils than the opposition does. We formalize this aspect of spoils politics as a signaling game in which the government has private information about the size of the spoils and tries to co-opt the opposition by offering a share of the spoils. The opposition can accept the offer or reject it by fighting. Consistent with the strong empirical finding that the probability of civil war is higher when income is low, the probability of breakdown increases as the size of the spoils decreases. We also study the effects of uncertainty, the opposition's military strength, the cost of fighting, and power-sharing agreements on the probability of fighting. [source] THE EFFECTS OF FISCAL AND MONETARY DISCIPLINE ON BUDGETARY OUTCOMESCONTEMPORARY ECONOMIC POLICY, Issue 2 2007BILIN NEYAPTI This article extends the model of Von Hagen and Harden that analyzed the impact of fiscal discipline on budgetary outcomes. We modify the model by adding monetary discipline to interact with fiscal discipline in order to analyze the effects of both on budgetary outcomes. The model predicts that while both inflation and budget deficits are negatively associated with fiscal discipline, they may be positively associated with monetary discipline, proxied by central bank independence. This result obtains due to optimizing agents internalizing the burden of spending: inflation. Although not conclusive due to data limitations, empirical findings also support these predictions. (JEL D73, E58, H61, H72) [source] Does the market value corporate environmental responsibility?CORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 2 2008An empirical examination Abstract Although researchers have applied different theoretical perspectives to illustrate the relationship between corporate environmental responsibility and profitability, to date theories are contested and empirical findings are inconclusive. Therefore, the aim of this research was to present empirical evidence regarding the influence of engaging in environmental responsibility on corporate market value, as the first study to be applied in the Egyptian context. The findings demonstrate that the market compensates those firms that care for their environment, as environmental responsibility exerted a positive and significant coefficient on the firm market value measured by Tobin's q ratio. This aligns stakeholder theory as well as resource-based theory arguments, and provides supporting evidence for those studies that have concluded that it pays to be environmentally responsive.

[source] Beliefs about worry in community-dwelling older adults,DEPRESSION AND ANXIETY, Issue 8 2006Ignacio Montorio Ph.D. Abstract This study examines the association between several kinds of beliefs about worry and generalized anxiety disorder (GAD) severity in a sample of older individuals recruited from a community setting (N=142, mean age=71.0 years, SD=6.0, range=55,88). Beliefs about worry were assessed with a 17-item scale designed for older adults, including three dimensions: Positive Beliefs, Negative Beliefs, and Responsibility. All three dimensions distinguished between people endorsing GAD symptoms and those without GAD symptoms, and only Negative Beliefs had a significant independent weight when regressed on GAD severity, even after controlling for level of trait worry. Results of this study suggest that negative beliefs appear to be strongly related to pathological worry in older adults. These results are consistent with empirical findings in younger adults and potentially support the use of particular interventions in clinical work with older adults with GAD.

[source] Patient-centred and professional-directed implementation strategies for diabetes guidelines: a cluster-randomized trial-based cost-effectiveness analysisDIABETIC MEDICINE, Issue 2 2006R. F. Dijkstra Abstract Aims Economic evaluations of diabetes interventions do not usually include analyses on effects and cost of implementation strategies. This leads to optimistic cost-effectiveness estimates. This study reports empirical findings on the cost-effectiveness of two implementation strategies compared with usual hospital outpatient care. It includes both patient-related and intervention-related cost. Patients and methods In a clustered-randomized controlled trial design, 13 Dutch general hospitals were randomly assigned to a control group, a professional-directed or a patient-centred implementation programme. Professionals received feedback on baseline data, education and reminders. Patients in the patient-centred group received education and diabetes passports. A validated probabilistic Dutch diabetes model and the UKPDS risk engine are used to compute lifetime disease outcomes and cost in the three groups, including uncertainties. Results Glycated haemoglobin (HbA1c) at 1 year (the measure used to predict diabetes outcome changes over a lifetime) decreased by 0.2% in the professional-change group and by 0.3% in the patient-centred group, while it increased by 0.2% in the control group. Costs of primary implementation were < 5 Euro per head in both groups, but average lifetime costs of improved care and longer life expectancy rose by 9389 Euro and 9620 Euro, respectively. Life expectancy improved by 0.34 and 0.63 years, and quality-adjusted life years (QALY) by 0.29 and 0.59. Accordingly, the incremental cost per QALY was 32 218 Euro for professional-change care and 16 353 for patient-centred care compared with control, and 881 Euro for patient-centred vs. professional-change care. Uncertainties are presented in acceptability curves: above 65 Euro per annum the patient-directed strategy is most likely the optimum choice. Conclusion Both guideline implementation strategies in secondary care are cost-effective compared with current care, by Dutch standards, for these patients. Additional annual costs per patient using patient passports are low. This analysis supports patient involvement in diabetes in the Netherlands, and probably also in other Western European settings. [source] Behavioral economic analysis of cue-elicited craving for alcoholADDICTION, Issue 9 2010James MacKillop ABSTRACT Aims Craving as a motivational determinant of drug use remains controversial because of ambiguous empirical findings. A behavioral economic approach may clarify the nature of craving, theorizing that subjective craving functionally reflects an acute increase in a drug's value. The current study tested this hypothesis via a multidimensional assessment of alcohol demand over the course of an alcohol cue reactivity procedure. Design One-way within-subjects design. Setting Human laboratory environment. Participants Heavy drinkers (n = 92) underwent exposures to neutral (water) cues followed by personalized alcohol cues. Assessments Participants were assessed for craving, alcohol demand, affect, and salivation following each exposure. Findings Alcohol versus neutral cues significantly increased craving and multiple behavioral economic measures of the relative value of alcohol, including alcohol consumption under conditions of zero cost (intensity), maximum expenditure on alcohol (Omax), persistence in drinking to higher prices (breakpoint) and proportionate price insensitivity (normalized Pmax). Craving was significantly correlated with demand measures at levels ranging from 0.21,0.43. Conclusions These findings support the potential utility of a behavioral economic approach to understanding the role of environmental stimuli in alcohol-related decision making. Specifically, they suggest that the behavioral economic indices of demand may provide complementary motivational information that is related to though not entirely redundant with measures of subjective craving. [source] Fluctuating Rounds of Inward Investment in Peripheral Regions: Semiconductors in the North East of EnglandECONOMIC GEOGRAPHY, Issue 1 2007Stuart Dawley Abstract: This article extends economic geography research on foreign direct investment episodes by developing a historically grounded understanding of the socio-institutional relations that shape and constrain different rounds of (dis)investment by multinational enterprises (MNEs) within a host region. Sensitive to the roles of contextuality, path dependency, and contingency, it argues that the temporal and spatial dynamics of volatile MNE (dis)investment are best tackled using a conceptual framework that accords a full and active role to the agency of the firm and its interrelations with the geographically variable socioinstitutional contexts that produce, regulate, and mediate investment decisions. The framework is used to interpret the brief but fluctuating history of the semiconductor fabrication industry in North Tyneside in the old industrial region of North East England. Within each investment episode, the empirical findings reveal the pivotal power and agency of the corporation in shaping and connecting processes across a variety of scales, places, and times. Contrasting corporate strategies illustrate the dynamic and contingent ways in which home and host national institutional contexts matter in mediating and regulating MNE investment decisions. [source] Capital Versus the Districts: A Tale of One Multinational Company's Attempt to Disembed ItselfECONOMIC GEOGRAPHY, Issue 2 2004N. A. Phelps Abstract: The process of international economic integration in which multinational enterprises (MNEs) play a significant orchestrating role is a contradictory one of a space of flows, on the one hand, and a space of places, on the other hand. It is this contradiction that produces a variegated landscape of relations within and among MNEs and a whole range of territorially rooted organizations and institutions. As a result, interest in global production networks, as part of a broader relational turn in economic geography, has sought to highlight and uncover these webs of relations within which MNEs are embedded. In reviewing this literature, we emphasize the economic imperatives underlying such relations or, rather, their political-economic nature and the discontinuities in industrial restructuring they can produce. We then present an empirical illustration of these points and some of the key concerns within the literature on global production networks. We consider a recent round of restructuring by Black & Decker Corporation, focusing on the politico-economic ramifications of closing one of two European factories. Our reading of the literature, coupled with our empirical findings, suggests the continuing tendency for international integration as a space of flows to eclipse the coherence of places. Localized points of resistance can moderate the powers exercised by MNEs internally and across a network of organizations, although there are limits to the transferability of such tactics of resistance. [source] ,Whatever is, is right'?ECONOMIC HISTORY REVIEW, Issue 4 2007Economic institutions in pre-industrial Europe Institutions,the structures of rules and norms governing economic transactions,are widely assigned a central role in economic development. Yet economic history is still dominated by the belief that institutions arise and survive because they are economically efficient. This article shows that alternative explanations of institutions, particularly those incorporating distributional effects, are consistent with economic theory and supported by empirical findings. Distributional conflicts provide a better explanation than efficiency for the core economic institutions of pre-industrial Europe: serfdom, the community, the craft guild, and the merchant guild. The article concludes by proposing four desiderata for any economic theory of institutions. [source] Do patents over-compensate innovators?ECONOMIC POLICY, Issue 52 2007Vincenzo Denicolò SUMMARY Do patents over-compensate innovators? Is the current level of patent protection too high or too low? To address this issue, this paper reformulates the theoretical analysis of the optimal level of patent protection to take into account the empirical findings of the innovation production function literature. This literature finds a strong relationship between R&D spending and inventions and estimates an elasticity of the supply of inventions of 0.5 or more. The paper then assesses the current level of patent protection, exploiting estimates of the private and social returns to R&D taken from the empirical literature and other available sources. Although more research is needed for a more precise assessment, the evidence available suggests that patents do not over-compensate innovators. ,Vincenzo Denicolò [source] POLITICAL AND JUDICIAL CHECKS ON CORRUPTION: EVIDENCE FROM AMERICAN STATE GOVERNMENTSECONOMICS & POLITICS, Issue 1 2008JAMES E. ALT This paper investigates the effects of checks and balances on corruption. Within a presidential system, effective separation of powers is achieved under a divided government, with the executive and legislative branches being controlled by different political parties. When government is unified, no effective separation exists even within a presidential system, but, we argue, can be partially restored by having an accountable judiciary. Our empirical findings show that a divided government and elected, rather than appointed, state supreme court judges are associated with lower corruption and, furthermore, that the effect of an accountable judiciary is stronger under a unified government, where the government cannot control itself. [source] ON THE ROLE OF THE PRIMARY SYSTEM IN CANDIDATE SELECTIONECONOMICS & POLITICS, Issue 2 2006MANDAR P. OAK How does the type of the primary system affect political outcomes? We address this issue by constructing a simple model that accounts for intra-party as well as inter-party political competition. Our model suggests that allowing non-partisan voters to participate in the primaries (i.e. a semi-open primary system) indeed improves the chances of a moderate candidate getting elected. However, this need not necessarily happen in the case of a completely open primary system. Under such a system there arise multiple equilibria, some of which may lead to a greater degree of extremism than the closed primary system. Thus, our model contributes to the current debate on the choice of primary systems from an analytical perspective and helps explain some of the empirical findings. [source] Researching Small Firms and Entrepreneurship in the U.K.: Developments and DistinctivenessENTREPRENEURSHIP THEORY AND PRACTICE, Issue 2 2008Robert A. Blackburn This article charts the development of research on small firms and entrepreneurship in the U.K. over the last 30 years or so and identifies distinctive characteristics of the current orientation of the research field. The paper analyses the rapid increase in the number of researchers contributing to the field over the period, together with its growing legitimacy and institutionalization. One of the key underlying themes is the rich diversity of approaches, reflecting the origins and development path, with clusters of researchers ranging from those with normative objectives to those who view the phenomenon as an object of study. Specific features of the U.K. research field identified include its policy orientation; a rich empirical tradition, with methodological diversity; an emphasis on small firms, and entrepreneurship as a subject for study, rather than an object for promotion; aspects of the boundaries and language of small business and entrepreneurship research; and pre-paradigmatic and middle range theory development i.e., somewhere between grand theory and empirical findings. [source] How (not) to operationalise subnational political opportunity structures: A critique of Kestilä and Söderlund's study of regional electionsEUROPEAN JOURNAL OF POLITICAL RESEARCH, Issue 3 2009KAI ARZHEIMER Based on an aggregate analysis of the French regional elections of 2004, Kestilä and Söderlund, in their 2007 article, ,Subnational Political Opportunity Structures and the Success of the Radical Right: Evidence from the March 2004 Regional Elections in France', examine the impact of subnational political opportunity structures on the success of the radical right and argue that such an approach can control for a wider range of factors and provide more reliable results than cross-national analyses. The present article disputes this claim on theoretical, conceptual and methodological grounds and demonstrates that their empirical findings are spurious. [source] SEXUAL ANTAGONISM AND THE EVOLUTION OF X CHROMOSOME INACTIVATIONEVOLUTION, Issue 8 2008Jan Engelstädter In most female mammals, one of the two X chromosomes is inactivated early in embryogenesis. Expression of most genes on this chromosome is shut down, and the inactive state is maintained throughout life in all somatic cells. It is generally believed that X-inactivation evolved as a means of achieving equal gene expression in males and females (dosage compensation). Following degeneration of genes on the Y chromosome, gene expression on X chromosomes in males and females is upregulated. This results in closer to optimal gene expression in males, but deleterious overexpression in females. In response, selection is proposed to favor inactivation of one of the X chromosomes in females, restoring optimal gene expression. Here, we make a first attempt at shedding light on this intricate process from a population genetic perspective, elucidating the sexually antagonistic selective forces involved. We derive conditions for the process to work and analyze evolutionary stability of the system. The implications of our results are discussed in the light of empirical findings and a recently proposed alternative hypothesis for the evolution of X-inactivation.
