This paper examines the relationship between the transfer of ownership between the public and private sectors of Chinese industry, and its impacts on performance. We link ownership changes to productivity growth, and demonstrate that privatisation contributes significantly. We offer an extension that is generally ignored in the literature, in looking at firms that are taken back into state ownership, and evaluating the productivity growth effects of this. Further, we highlight the well-understood simultaneity problems, and demonstrate the hazard of ignoring the issue by comparing various estimators, including the modified control function approach. In general, the results stress the importance of allowing for such endogeneity when evaluating the productivity effects of ownership change.

Bove, Pervan, Beatty, and Shiu [Bove, LL, Pervan, SJ, Beatty, SE, Shiu, E. Service worker role in encouraging customer organizational citizenship behaviors. J Bus Res 2009;62(7):698–705.] develop and test a latent variable model of the role of service workers in encouraging customers' organizational citizenship behaviors. However, Bove et al. [Bove, LL, Pervan, SJ, Beatty, SE, Shiu, E. Service worker role in encouraging customer organizational citizenship behaviors. J Bus Res 2009;62(7):698–705.] claim support for hypothesized relationships between constructs that, due to insufficient discriminant validity regarding certain constructs, may be inaccurate. This research comment discusses what discriminant validity represents, procedures for establishing discriminant validity, and presents an example of inaccurate discriminant validity assessment based upon the work of Bove et al. [Bove, LL, Pervan, SJ, Beatty, SE, Shiu, E. Service worker role in encouraging customer organizational citizenship behaviors. J Bus Res 2009;62(7):698–705.]. Solutions to discriminant validity problems and a five-step procedure for assessing discriminant validity then conclude the paper. This comment hopes to motivate a review of discriminant validity issues and offers assistance to future researchers conducting latent variable analysis.

Recent studies of new institutional spaces typically underplay the uneven and contested process of institutional change by undervaluing the role of inherited institutions and discourses. This is a critical issue as neoliberal networked forms of governance interact with inherited institutional arrangements, characterised by important path dependencies that guide actors. Contradiction and tensions can emerge, culminating in crisis tendencies, and producing both discursive and material contestation between actors. It is with an understanding of path dependencies, ideas (structured into discourses), and (perceived and actual) crisis tendencies that this paper examines contested institutional change through a case-study analysis of one city, and a critical engagement with neoinstitutionalism. The purpose is to examine, firstly, the significance of inherited path-dependent arrangements in fostering conflict and crisis tendencies during interaction with emergent state action; secondly, the extent to which crisis is evident in processes of institutional change and the form that this takes; and, thirdly, the importance of ideas in producing institutional transformation. It is found that institutional conflict is evident between inherited institutions and emergent state action, and stems both from the way agents are organised by the state and from certain path dependencies, but that this does not lead to an actual material crisis. Rather, the nation-state, in partnership with senior city government actors, use ideational/discursive ‘crisis talk’ as a means by which to induce institutional change. The role of ideas has been in critical in this process as the nation-state frames problems and solutions in line with its existing policy paradigm and institutional arrangements, and with discourses further reinforcing existing material power relations.

Around 50 per cent of men with diabetes experience erectile dysfunction. Much of the literature focuses on quality of life measures with heterosexual men in monogamous relationships. This study explores gay and bisexual men's experiences of sex and diabetes. Thirteen interviews were analysed and three themes identified: erectile problems; other 'physical' problems; and disclosing diabetes to sexual partners. Findings highlight a range of sexual problems experienced by non-heterosexual men and the significance of the cultural and relational context in which they are situated. The personalized care promised by the UK government should acknowledge the diversity of sexual practices which might be affected by diabetes.

The relationship between theory and practice has been discussed in the social sciences for generations. Academics from management and organization studies regularly lament the divide between theory and practice. They regret the insufficient academic knowledge of managerial problems and their solutions, and criticize the scholarly production of theories that are not relevant for organizational practice (Hambrick 1994). Despite the prevalence of this topic in academic discourse, we do not know much about what kind of academic knowledge would be useful to practice, how it would be produced and how the transfer of knowledge between theory and practice actually works. In short, we do not know how we can make academic work more relevant for practice or even whether this would be desirable. In this introduction to the Special Issue, we apply philosophical, theoretical and empirical perspectives to examine the challenges of studying the generation and use of academic knowledge. We then briefly describe the contribution of the seven papers that were selected for this Special Issue. Finally, we discuss issues that still need to be addressed, and make some proposals for future avenues of research.

This research examines women GPs' careers, how they run their practices and how they reconcile professional and domestic lives. It looks at the particular experiences of women GPs who practise alone, and at the pressures in past practice experience which have led them to do so. It is argued that many of the problems of group practice which can be identified are attributable to gender. For example, one reason given for entering general practice is a desire to be able to provide the full range of medical care and not to specialise. Women GPs, however, may find themselves seeing more women patients for "women's problems" and children than they would freely choose. Women have not entered general practice in order to specialise in these areas of medicine. Indeed, if they had wanted to specialise in obstetrics, gynaecology or paediatrics they would have had difficulty advancing very far in these male-dominated areas of hospital hierarchy. Other gender related problems exist for women in general practice and practising single-handedly is one strategy that women GPs have used to counter the problems of working in male-dominated practices and partnerships. However, the twenty-four hour commitment of single-handed practice may bring further pressures in reconciling this with responsibility for home life. Out-of-hours cover, which can be viewed as the link between professional and domestic life, where the one intrudes into the other, is also examined in terms of the gender issues it raises. The interaction of gender and ethnicity is also considered for the 11 Asian women GPs in the study. Interviews were conducted with 29 single-handed women GPs in the Midlands. In addition, some cases were studied in greater depth by being observed in their surgeries and on home visits for a day each. A qualitative/feminist approach to analysis has been employed.

The confusion over the concept of accessibility in transport planning and the deficiencies of existing accessibility indices are examined by developing a conceptual framework of accessibility with a fundamental distinction being drawn between the, often conflicting, theoretical and practical dimensions. The theoretical validity of alternative indices is assessed with reference to the problems and assumptions implicit in defining, measuring, valuing and aggregating the variables and components comprising accessibility. The major deficiencies of existing indices are identified as the inability of indices to take account of the potential to link trips between more than one activity location and the level of assumptions implicit in valuing and aggregating accessibility information. In this context, it is argued that accessibility information is more appropriately expressed on a comparative basis in the form of a profile rather than as a composite single-unit index and that the present confines of accessibility measurement must be extended in line with current developments in disaggregate travel and activity modelling. The sensitivity of accessibility levels to the use of alternative value judgements, alternative forms and levels of aggregation and the inclusion of information on the potential to link trips is examined by undertaking a case study. Accessibility profiles are developed for 23 zones in the London Borough of Hammersmith and Fulham showing the accessibility of the elderly to post offices and grocers. In a practical context, the profiles assist in identifying areas and individuals with relatively poor accessibility. The incidence and nature of linked trip-making and its significance and implications for accessibility measurement are explored further by analysing the results of a survey of the elderly's travel patterns. It is concluded that future accessibility analysis should be undertaken at a disaggregate level, taking account of the potential opportunity available from nonhome as well as home origins.

Despite the increasing popularity of research on intercultural preparation and its effectiveness, research on training for inpatriates has not been developed with the same level of rigour as research on training for expatriates. Furthermore, research on intercultural training hardly ever includes the aspect of preparing for the corporate culture of a company. For expatriates coming from headquarters’ national culture and equipped with a good knowledge of headquarters’ corporate culture, it might be sufficient to address only the national culture of the location abroad. But can the same be said for inpatriates coming from a foreign subsidiary? Therefore the qualitative research of my thesis was aimed at finding out if intercultural training programmes that address only the national culture of the host country are sufficient to prepare inpatriates for working at headquarters. A case study using a German multinational company has been conducted in order to find out what kind of problems and irritations inpatriates at the company’s headquarters perceive at work. In order to determine whether the findings are related to the national or the corporate culture, Hall’s and Hofstede’s approaches to culture were used. The interview analysis produced the following conclusion: Although the researched company promotes standardised worldwide corporate guidelines, there are many differences between headquarters and subsidiaries regarding the interpretation and realisation of these guidelines. These differences cause irritation, confusion and problems for the inpatriates. Therefore an effective intercultural preparation for inpatriates should be tailor-made and take into account the aspect of corporate culture, as well as the specific roles and functions of inpatriates.

The research reported here is an investigation into the problems of social and economic development of a multiethic and multicultural country which has the added challenge of adopting a non-indigenous code to facilitate the development process. Malaysia's power to negotiate outcomes favourable to the interest of the country is critical for the successful attainment of the goals and objectives of VISION2020. Therefore the mechanisms of the human resource development programme have to be efficacious. The three hypotheses of this study are as follows: 1. there is a fear that the problems and challenges posed by the development plans, have been conceptually trivialised; 2. based on (1) above there is a concern that solutions proposed are inadequate and inappropriate and 3. the outcome of both (1) and (2) can lead to the potential underachievement of national goals and objectives. The study proposes a complex model for conceptualising the problem which looks at the relationship between society and language, which any solutions proposed must take into proper consideration. The study looks at the mechanisms available for the smooth absorption of new Malaysian members to new and international communities. A large scale investigation was undertaken with the researcher functioning as a participant observer. An in-depth study of one particular educational ecology yielded approximately 38 hours of interviews and 100 questionnaires. These data were analysed both for explicit information and implicit implications. By some criteria national policies appear to be having the desired effect, and can be given a clean bill of health. By others it is clear that major adjustments would be necessary if the nation is to achieve its objectives in full. Based on the evidence gathered, thr study proposes an apprenticeship approach to training programmes for effective participation of new members in the new ecologies.

How effective are non-government organisations (NG0s) in their response to Third World poverty? That is the question which this thesis examines. The thesis begins with an overview of the problems facing Third World communities, and notes the way in which people in Britain have responded through NG0s. A second part of the thesis sets out the issues on which the analysis of NGOs has been made. These are: - the ways in which NGOs analyse the process of development; - the use of 'improving nutrition' and 'promoting self-reliance' as special objectives by NG0s; and - the nature of rural change, and the implications for NGOs as agents of rural development. Kenya is taken as a case study. Firstly the political and economic structure of the country is studied, and the natures of development, nutritional problems and self-reliance in the Kenyan context are noted. The study then focusses attention onto Kitui District, an area of Kenya which at the time of the study was suffering from drought. However, it is argued that the problems of Kitui District and the constraints to change there are as much a consequence of Kenya's structural underdevelopment as of reduced rainfall. Against this background the programmes of some British NGOs in the country are examined, and it is concluded that much of their work has little relevance to the principal problems which have been identified. A final part of the thesis takes a wider look at the policies and practices of NG0s. Issues such as the choice of countries in which NGOs work, how they are represented overseas, and their educational role in Britain are considered. It is concluded that while all NGOs have a concern for the conditions in which the poorest communities of the Third World live, many NGOs take a quite narrow view of development problems, giving only little recognition to the international and intranational political and economic systems which contribute to Third World poverty.

This thesis is concerned with Organisational Problem Solving. The work reflects the complexities of organisational problem situations and the eclectic approach that has been necessary to gain an understanding of the processes involved. The thesis is structured into three main parts. Part I describes the author's understanding of problems and suitable approaches. Chapter 2 identifies the Transcendental Realist (TR) view of science (Harre 1970, Bhaskar 1975) as the best general framework for identifying suitable approaches to complex organisational problems. Chapter 3 discusses the relationship between Checkland's methodology (1972) and TR. The need to generate iconic (explanatory) models of the problem situation is identified and the ability of viable system modelling to supplement the modelling stage of the methodology is explored in Chapter 4. Chapter 5 builds further on the methodology to produce an original iconic model of the methodological process. The model characterises the mechanisms of organisational problem situations as well as desirable procedural steps. The Weltanschauungen (W's) or "world views" of key actors is recognised as central to the mechanisms involved. Part II describes the experience which prompted the theoretical investigation. Chapter 6 describes the first year of the project. The success of this stage is attributed to the predominance of a single W. Chapter 7 describes the changes in the organisation which made the remaining phase of the project difficult. These difficulties are attributed to a failure to recognise the importance of differing W's. Part III revisits the theoretical and organisational issues. Chapter 8 identifies a range of techniques embodying W's which are compatible with .the framework of Part I and which might usefully supplement it. Chapter 9 characterises possible W's in the sponsoring organisation. Throughout the work, an attempt 1s made to reflect the process as well as the product of the author's leaving.

The objective of this thesis is to investigate, through an empirical study, the different functions of the highways maintenance departments and to suggest methods by means of which road maintenance work could be carried out in a more efficient way by utilising its resources of men, material and plant to the utmost advantage. This is particularly important under the present circumstances of national financial difficulties which have resulted in continuous cuts in public expenditure. In order to achieve this objective, the researcher carried out a survey among several Highways Authorities by means of questionnaire and interview. The information so collected was analysed in order to understand the actual, practical situation within highways manintenance departments, and highlight any existing problems, and try to answer the question of how they could become more efficient. According to the results obtained by the questionnaire and the interview, and the analysis of these results, the researcher concludes that it is the management system where least has been done, and where problems exist and are most complex. The management of highways maintenance departments argue that the reasons for their problems include both financial and organisational difficulties, apart from the political aspect and nature of the activities undertaken. The researcher believes that this ought to necessitate improving the management's analytical tools and techniques in order to achieve the most effective way of performing each activity. To this end the researcher recommends several related procedures to be adopted by the management of the highways maintenance departments. These recommendations, arising from the study, involve the technical, practical and human aspects. These are essential factors of which management should be aware - and certainly should not neglect - in order to achieve its objectives of improved productivity in the highways maintenance departments.

The thesis presents an account of an attempt to utilize expert systems within the domain of production planning and control. The use of expert systems was proposed due to the problematical nature of a particular function within British Steel Strip Products' Operations Department: the function of Order Allocation, allocating customer orders to a production week and site. Approaches to tackling problems within production planning and control are reviewed, as are the general capabilities of expert systems. The conclusions drawn are that the domain of production planning and control contains both `soft' and `hard' problems, and that while expert systems appear to be a useful technology for this domain, this usefulness has by no means yet been demonstrated. Also, it is argued that the main stream methodology for developing expert systems is unsuited for the domain. A problem-driven approach is developed and used to tackle the Order Allocation function. The resulting system, UAAMS, contained two expert components. One of these, the scheduling procedure was not fully implemented due to inadequate software. The second expert component, the product routing procedure, was untroubled by such difficulties, though it was unusable on its own; thus a second system was developed. This system, MICRO-X10, duplicated the function of X10, a complex database query routine used daily by Order Allocation. A prototype version of MICRO-X10 proved too slow to be useful but allowed implementation and maintenance issues to be analysed. In conclusion, the usefulness of the problem-driven approach to expert systems development within production planning and control is demonstrated but restrictions imposed by current expert system software are highlighted in that the abilities of such software to cope with `hard' scheduling constructs and also the slow processing speeds of such software can restrict the current usefulness of expert systems within production planning and control.

Government regulation of industrial hazards is examined in the context of the economic and technical processes of industrial development. Technical problems and costs of control are considered as factors in both the formation and impact of regulation. This thesis focuses on an historical case-study of the regulation of the hazard to painting workers from the use of lead pigments in paint. A regulatory strategy based on the prohibition of lead paints gained initial acceptance within the British state in 1911, but was subsequently rejected in favour of a strategy that allowed continued use of lead paint subject to hygiene precautions. The development of paint technology and its determinants, including concern about health hazards, are analysed, focusing on the innovation and diffusion into the paint industry of the major white pigments: white lead (PbC03 .PB(OH)2)and its substitutes. The process of regulatory development is examined, and the protracted and polarised regulatory d~bate contrasted to the prevailing 'consensual' methods of workplace regulation. The rejection of prohibition is analysed in terms of the different political and technical resources of those groups in conflict over this policy. This highlights the problems of consensus formation around such a strategy, and demonstrates certain constraints on state regulatory activity, particularly regarding industrial development. Member-states of the International Labour Organisation agreed to introduce partial prohibition of lead paint in 1921. Whether this was implemented is related to the economic importance of lead and non-lead metal and pigment industries to a nation. An analysis is made of the control of lead poisoning. The rate of control is related to the economic and technological trajectory of the regulated industry. Technical and organisational characteristics are considered as well as regulatory factors which range from voluntary compliance and informal pressures to direct legal requirements. The implications of this case-study for the analysis of the development and impacts of regulation are assessed.
