Abstract
Chance models – mechanisms that explain empirical regularities through unsystematic variance – have a long tradition in the sciences but have been historically marginalized in management scholarship, relative to an agentic worldview about the role of managers and organizations. An exception is the work of James G. March and his coauthors, who proposed a variety of chance models that explain important management phenomena, including the careers of top executives, managerial risk taking, and organizational anarchy, learning, and adaptation. This paper serves as a tribute to the beauty of these “little ideas” and demonstrates how they can be recombined to generate novel implications. In particular, we focus on the example of an inverted V-shaped performance association centering around the year when executives were featured in a prominent listing, Barron’s annual list of Top 30 chief executive officers. Our recombination of several chance models developed by March and his coauthors provides a novel explanation for why many of the executives’ exceptional performances did not persist. In contrast to the common accounts of complacency, hubris, and statistical regression, the results show that declines from high performance may result from the way luck interacts with these executives’ slow adaptation, incompetence, and self-reinforced risk taking. We conclude by elaborating on the normative implications of chance models, which address many current management and societal challenges. We further encourage the continued development of chance models to help explain performance differences, shifting from accounts that favor heroic stories of corporate leaders toward accounts that favor their changing fortunes.

Abstract
The librarian and researcher have to be able to uncover specific articles in their areas of interest. This Bibliography is designed to help. Volume IV, like Volume III, contains features to help the reader to retrieve relevant literature from MCB University Press' considerable output. Each entry within has been indexed according to author(s) and the Fifth Edition of the SCIMP/SCAMP Thesaurus. The latter thus provides a full subject index to facilitate rapid retrieval. Each article or book is assigned its own unique number and this is used in both the subject and author index. This Volume indexes 29 journals indicating the depth, coverage and expansion of MCB's portfolio.

Abstract
Genetic and environmental factors are associated with psychosis risk, but the latter present more tangible markers for prevention. We conducted a theoretical exercise to estimate the proportion of psychotic illnesses that could be prevented if we could identify and remove all factors that lead to increased incidence associated with ethnic minority status and urbanicity. Measures of impact by population density and ethnicity were estimated from incidence rate ratios [IRR] obtained from two methodologically‐similar first episode psychosis studies in four UK centres. Multilevel Poisson regression was used to estimate IRR, controlling for confounders. Population attributable risk fractions [PAR] were estimated for our study population and the population of England. We considered three outcomes; all clinically relevant ICD‐10 psychotic illnesses [F10‐39], non‐affective psychoses [F20‐29] and affective psychoses [F30‐39]. One thousand and twenty‐nine subjects, aged 18‐64, were identified over 2.4 million person‐years. Up to 22% of all psychoses in England (46.9% within our study areas) could be prevented if exposures associated with increased incidence in ethnic minority populations could be removed; this is equivalent to 66.9% within ethnic minority groups themselves. For non‐affective psychoses only, PAR for population density was large and significant (27.5%); joint PAR with ethnicity was 61.7%. Effect sizes for common socio‐environmental risk indicators for psychosis are large; inequalities were marked. This analysis demonstrates potential importance in another light: we need to move beyond current epidemiological approaches to elucidate exact socio‐environmental factors that underpin urbanicity and ethnic minority status as markers of increased risk by incorporating gene‐environment interactions that adopt a multi disciplinary perspective.

Abstract
This chapter presents research to assess the impact of the recent financial crisis on technology-based small firms (TBSFs) in the United Kingdom based on findings from an extended telephone survey with the owner-managers of 49 young and 51 more mature TBSFs, undertaken in 2010. Even before the onset of the global financial crisis in 2007, it was generally acknowledged that TBSFs faced greater obstacles in accessing finance than conventional SMEs. This is because banks have difficulty assessing the viability of new technology-based business ventures due to information asymmetries, whilst risk capital providers may have difficulty providing appropriate or sufficient funds on terms acceptable to entrepreneurs. Given the recent difficulties that SMEs, in general, have faced in obtaining external finance, we would expect TBSFs to have been particularly adversely affected by the financial crisis. Our evidence showed that TBSFs exhibited a strong demand for external finance between 2007 and 2010, related to their growth ambitions and achievements. They sought finance mainly from banks but also with younger TBSFs seeking business angel finance and more mature TBSFs seeking venture capital finance. However, our evidence indicates that both debt and equity finance became harder to access for TBSFs, particularly for early-stage and more R&D-intensive firms. Where funding was offered, it was often on unacceptable terms with regards to the levels of collateral or equity required. The chapter provides evidence of a growing funding gap and concludes that the ability of TBSFs to contribute to economic recovery is hampered by ongoing problems in obtaining external finance.

Abstract
In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract
The paper focuses on the question of the extent to which individual preference-based values are suitable in guiding environmental policy and damage assessment decisions. Three criteria for “suitableness” are reviewed: conceptual, moral and legal. Their discussion suggests that: (i) the concept of economic value as applied to environmental resources is a meaningful concept based on the notion of trade-off; (ii) the limitations of the moral foundations of cost-benefit analysis do not invalidate its use as a procedure for guiding environmental decision making; (iii) the input of individual preferences into damage assessment is compatible with the basic foundations of tort law; (iv) using individual preference-based methods provides incentives for efficient levels of due care; (v) determining standing is still very contentious for various categories of users as well as for aggregating non-use values. Overall, the discussion suggests that the use of preference-based approaches in both the policy and legal arenas is warranted provided that they are accurately applied, their limitations are openly acknowledged and they assume an information-providing rather than a determinative role.

Abstract
Sustainable development in support of cultural heritage has become one of the major issues on UNESCO’s agenda. As policy documents are issued, heritage environmental sustainability, local stakeholders’ development and participation and heritage in cases of interregional conflict are the situations they analyze. As such, policy documents will be employed as guidelines for past and future UNESCO World Heritage site registrations. They have been used for the present study of sustainable development within mostly Thai cultural heritage context, with a few cases relating to Cambodia due the lack of research on this topic in the region. Employing qualitative method analysis, most of the heritage sites studied here suffer from a lack of protection against encroachment, natural elements and, more rarely, overuse. Furthermore, the implementation of heritage management plans sees local stakeholders excluded from any participation in the heritage they live in, which may cause conflicts in Southeast Asia.

Abstract
In recent years, a wide range of psychosocial health interventions have been implemented among military service members and their families. However, there are questions over the evaluative rigor of these interventions. We conducted a systematic review of this literature, rating each relevant study (k = 111) on five evaluative rigor scales (type of control group, approach to participant assignment, outcome quality, number of measurement time points, and follow-up distality). The most frequently coded values on three of the five scales (control group type, participant assignment, and follow-up distality) were those indicating the lowest level of operationally defined rigor. Logistic regression results indicate that the evaluative rigor of intervention studies has largely remained consistent over time, with exceptions indicating that rigor has decreased. Analyses among seven military sub-populations indicate that interventions conducted among soldiers completing basic training, soldiers returning from combat deployment, and combat veterans have had, on average, the greatest evaluative rigor. However, variability in mean scores across evaluative rigor scales within sub-populations highlights the unique methodological hurdles common to different military settings. Recommendations for better standardizing the intervention evaluation process are discussed.

Abstract
Young men of African‐Caribbean origin are over‐represented in mental health services (MHSs), often entering these services by coercive routes, such as under the Mental Health Act or via the criminal justice system. This pilot study focused on patients' narratives of their journey from first contact with primary care services. Our principal aim was to describe and compare early experiences of help‐seeking for serious mental health problems among young men of white and black ethnicity.In‐depth interviews were conducted (using a topic guide) with black and white men aged 18‐30 years old and who were accessing secondary care mental health services for the first time for a psychotic illness. Participants were recruited from the early intervention services serving inner‐city Birmingham. Seven participants were interviewed, and 12 themes were identified from transcripts. Six of these individuals had consulted their GP prior to accessing the early intervention service. Only one attendee received medication at initial consultation, and none were referred to specialist mental health services. Participants described the manner in which family or friends interceded on their behalf to advocate for and secure specialist help ‐ either by accompanying them to see their GP, contacting mental health services directly or taking them to the local accident and emergency department. The latter route was accessed by black but not white participants. Three out of four black participants and one out of three white participants were subsequently admitted to hospital. None of the participants were particularly satisfied with their experience of primary care. Communication was less than ideal, and participants were able to reflect on their own failure to disclose critical information to their doctor. By contrast, all participants confided in family or in their trusted friends that they were becoming aware that they were experiencing mental distress.Our findings confirm the difficulties faced by GPs and those who consult them in the early stages of first onset psychotic episodes, and the importance of having family or friends who are able to advocate on other people's behalf at times of crisis. Despite the advent of universal early intervention services across the UK, those most in need may still not be receiving the help that they need in the timeliest manner.
