Purpose – This article aims to contribute to the re-evaluation of the global market system using a Marxist inspired theory of development, dependency.

Design/methodology/approach – This article draws on dependency theory as an alternative means of understanding global relationships. Building on existing literature, it modifies dependency to encapsulate technological developments and trends in the global market.

Findings – Re-evaluating the global market and the relationships that underpin it, through an alternative theory, highlights the fragility of markets and associated relationships. Increasingly, nation states are becoming irrelevant. This presents a problem as the main actors in the global market today are “above” inter-state relations, yet the organs that regulate their behaviour still are grounded in inter-state rhetoric. The relationship between development and underdevelopment remains.

Research limitations/implications – The financial crisis has propagated a wealth of interest in the relationships between states, between multi-national corporations (MNCs) and between MNCs and state. Using this broad theory of modified dependency, it can be applied to a range of different relationships. In the wake of financial crisis, there is the opportunity to raise awareness of these ingrained issues and initiate discussions at national, regional and international levels to alleviate some of the conditions of dependence.

Practical implications – Regardless of the work of national governments and NGOs to instigate development in lesser-developed regions through policy and regulations, unless there is a conscientious commitment from MNCs operating in that region to contribute to development, the result will be the development of underdevelopment and the underdevelopment of development. CSR can help alleviate the conditions of the dependence on capital generated by MNCs, but this is not a solution to an ingrained problem, capitalism.

Originality/value – This article introduces a modified theory of dependency for the first time. It applies the theory to the financial crisis and to the continent of Africa. It considers the role that CSR can play in alleviating the conditions of dependence.

Purpose – The purpose of this paper is to consider the occupational stress experienced by chefs and the moderating influence of coping behaviour and locus of control on stress outcomes. Design/methodology/approach – A total of 40 working chefs were surveyed. They were asked to complete an occupational stress questionnaire, the General Health Questionnaire. Differences were
sought between gender and locus of control and stress measures, and correlations were carried out between key variables. Findings – The reported stress was markedly higher than in previous research. Excessive workload,
feeling undervalued and communication issues were common and bullying and threats of violence were present for some. Unexpectedly, locus of control was unable to predict stress experiences. Explanations were offered, such as the possibility that those who perceive they have a strong sense of control may believe that this, paradoxically, affords them the opportunity to engage in unhealthy behaviours. Research limitations/implications – Limitations of the research include the influence of the wider environment, specifically the history of political violence in the province, and its possible effect on stress outcomes. However, this may be negated by the many positive effects peace has brought over the last decade. In drawing conclusions it is important to note the limitations of the sample size and the self-reporting nature of survey responses. Further research could usefully incorporate well-being as well as stress measures, including physiological ones. It would be worth exploring further how one’s sense of control affects perceptions of stress and, in turn, the coping behaviours engaged in. Practical implications – Practical implications include the need for managers and head chefs to provide more feedback to employees, to validate their good work and to foster a supportive working environment. Norms in the working environment endorsing aggressive behaviour must be challenged.
Staff appraisals should consider the need to have work that involves variety and challenge, especially where changes involve increases in workload. Originality/value – This paper identifies some important ingredients to reduce distress and it will be of value to chefs and other kitchen staff and, more broadly, to those involved in people management.

Objective: To compare maternal and fetal leptin among women without diabetes, women with type 1 diabetes, and women with type 2 diabetes. 

Methods: In a prospective study at the National Maternity Hospital, Dublin, 40 women with type 1 diabetes, 10 with type 2 diabetes, and 30 without diabetes were enrolled between July 2006 and July 2008. Maternal (36-week) and cord blood leptin was measured by enzyme-linked immunoassay. 

Results: No difference was found in maternal leptin among the groups: without diabetes (mean, range): 325 pg/mL, 36-1492 pg/mL; type 1 diabetes: 343.2 pg/mL, 55.5-1108.2 pg/mL; type 2 diabetes: 2022 pg/mL, 35.1-1553.3 pg/mL (P>0.05). Leptin levels were higher among fetuses of women with type 1 (223 pg/mL, 25.7-810 pg/mL) and type 2 (447.2 pg/mL, 1363-679 pg/mL) diabetes than among women without diabetes (803 pg/mL, 273-623.1 pg/mL; P<0.05). The single significant predictor of fetal leptin for the whole cohort was maternal body mass index (BMI; r=039, P=0.01). Only third-trimester glycosylated hemoglobin (HbA1c) was significantly related to fetal leptin after controlling for maternal BMI among women with diabetes (r=028, P=0.04).

 Conclusion: Fetuses of women with diabetes might have some degree of leptin resistance. This might be important in appetite regulation in extrauterine life. (C) 2012 International Federation of Gynecology and Obstetrics.

Purpose: The purpose of this paper is to add to current discussions on the use of Lacanian psychoanalysis in organizational change. Specifically, It argues that critiques of Lacan's work must be acknowledged and incorporated into these discussions. To date, there remains a silence surrounding these critiques within organization studies.
Design/methodology/approach: The paper presents the existing studies that draw upon Lacan's work in the context of organizational change initiatives. It highlights the value of this theory. Next, it outlines critiques of Lacan's concepts of phallus and incest taboo, and show how these concepts can be exclusionary.
Findings: The paper finds that there remains little debate within organization studies around such critiques. Lacan tends to be employed in ways that risk reproducing particular, exclusionary aspects of his theory. A homophobic and patriarchal legacy persists in appropriations of his writing. It outlines alternative ways of reading Lacan, which aim to avoid such exclusions. It shows how introducing such alternatives is a difficult project, first, given the silence surrounding critiques of Lacan in the organizational change literature. Second, following Foucault, It argues that language has power: a patriarchal schema is self-reinforcing in its persistence within a particular discipline, and thus difficult to dislodge.
Research limitations/implications: Given these findings, the paper concludes that organization theorists and practitioners ought to engage with critiques of Lacan's work, when employing it in their own. The silence surrounding such legacies is dangerous. It argues that the first step in engaging with Lacan's work should be to give voice to such critiques, if his writing is to be employed in the practice and study of organizational change.
Originality/value: This paper provides a unique engagement with Lacan's work in the context of the study and practice of organizational change interventions. It presents an evaluation of well-known critiques and useful recommendations for theorists and practitioners considering a Lacanian approach to this area of management studies. © Emerald Group Publishing Limited.

Purpose: The paper aims to analyse Bottom of the Pyramid (BoP) customers’ (e.g. Bangladeshi farmers) use and appropriation of mobile telephony and to critically identify a suitable research strategy for such investigation.

Design/methodology/approach: Concentrated ethnographic immersion was combined with both methodological and investigator triangulation during a four-month period of fieldwork conducted in Bangladeshi villages to obtain more robust findings. Concentrated immersion was required to achieve relatively speedier engagement owing to the difficulty in engaging with respondents on a long-term basis.

Findings: The farmers’ use of mobile telephony went beyond the initial adoption, as they appropriated it through social and institutional support, inventive means and/or changes in their own lifestyle. The paper argues that technology appropriation, being a result of the mutual shaping of technology, human skills and abilities and macro-environmental factors, enables users to achieve desired outcomes which may not always be the ones envisaged by the original designers.

Research limitations/implications: The paper contributes to two major areas: first, it identifies technology appropriation as an important and emerging concept in international marketing research; second, it suggests a concentrated form of ethnographic engagement for studying technology appropriation in a developing country context.

Practical implications: A good understanding of the dynamic interplay between users’ skills and abilities, social contexts and technological artefacts/applications is required in order for businesses to serve BoP customers profitably.

Originality/value: The paper presents a dynamic model of technology appropriation based on findings collected through a pragmatic approach by combining concentrated ethnographic immersion with methodological and investigator triangulation

Very-low-density lipoproteins (VLDL) (density less than 1.006 g/mL) were isolated from type I (insulin-dependent) diabetic patients in good to fair glycemic control and from age-, sex-, and race-matched, nondiabetic, control subjects. VLDL were incubated with human, monocyte-derived macrophages obtained from nondiabetic donors, and the rates of cellular cholesteryl ester synthesis and cholesterol accumulation were determined. VLDL isolated from diabetic patients stimulated significantly more cholesteryl ester synthesis than did VLDL isolated from control subjects (4.04 +/- 1.01 v 1.99 +/- 0.39 nmol 14C-cholesteryl oleate synthesized/mg cell protein/20 h; mean +/- SEM, P less than .05). The stimulation of cholesteryl ester synthesis in macrophages incubated with VLDL isolated from diabetic patients was paralleled by a significant increase in intracellular cholesteryl ester accumulation (P less than .05). The increase in cholesteryl ester synthesis and accumulation in macrophages were mediated by a significant increase in the receptor mediated, high affinity degradation (2.55 +/- 0.23 v 2.12 +/- 0.20 micrograms degraded/mg cell protein/20 h) and accumulation (283 +/- 35 v 242 +/- 33 ng/mg cell protein/20 h) of 125I-VLDL isolated from diabetic patients compared with VLDL from control subjects. To determine if changes in VLDL apoprotein composition were responsible for the observed changes in cellular rates of cholesteryl ester synthesis and accumulation, we also examined the apoprotein composition of the VLDL from both groups. There were no significant differences between the apoproteins B, E, and C content of VLDL from both groups. We also determined the chemical composition of VLDL isolated from both groups of subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Purpose: This paper aims to provide a brief overview of the global financial crisis (GFC), highlighting its most frightening dimensions, the policy responses and issues around the management of labour during and post-GFC. Further, this paper introduces the five research papers that encompass this special issue. Design/methodology/approach: The papers presented here are early contributions on how the GFC has impacted the management of people. The key areas focused upon include the human resource management responses of multinational enterprises, the response of trade unions, the roles of employee representative bodies and the rationalisation of post-crisis managerial strategies. Findings: The major conclusions of this special issue are that the impact of the GFC was variable across countries and sectors in addition to the process of decision making, the types of decisions made, and the determinants and consequences of those decisions. Originality/value: The papers of the special issue provide some of the first empirical findings on how the GFC has impacted on people management, trade unions and the HR function in different contexts. © Emerald Group Publishing Limited.

Purpose - The purpose of this paper is to examine the pattern of outward foreign direct investment (FDI) by Irish MNCs, and more specifically, to investigate their approach to human capital development and how these correspond to foreign MNCs in Ireland. In particular, it seeks to investigate training and development expenditure, adoption of succession planning, use of formal development programmes for senior management "potential", and also the presence of a specific "key group" development programme. Design/methodology/approach - Data were obtained through the largest, most representative study ever conducted on multinational companies (MNCs) in Ireland. The most senior human resources practitioner in these firms completed a questionnaire, through the personal interview medium, on various facets of their human resource management (HRM) practices. In total 260 usable interviews were completed equating to an overall response rate of 63 per cent. This represents a 78 per cent response rate for Irish MNCs, the primary focus of this paper, and 60 per cent for foreign MNCs. Findings - Overall, Irish MNCs tend to compare favourably with their foreign counterparts in terms of the human capital development mechanisms examined. Only one statistically significant association was found regarding differences between Irish and foreign owned MNCs, Irish MNCs were found to be significantly less likely to have formal management development programmes. Originality/value - The study is the first large scale, representative survey to be conducted on MNCs in Ireland helping to address the research lacuna on Irish owned MNCs. © Emerald Group Publishing Limited.

Purpose: This article discusses the opportunities presented by the globalization of education and the role of knowledge management in successful global expansion. It seeks to explain why the tacit dimensions of the knowledge transferred during international education provision makes it difficult to provide educational services in offshore campuses, absent the transfer of people. Design/methodology/approach: The article draws on literature in the discipline of international business to explain why internationalizing universities need to consider the role of knowledge transfer as a strategic imperative. As this is a conceptual article, arguments are built on insights from extant theoretical and empirical work. Findings: Based on the analysis of a diverse body of academic literature in the areas of international business, knowledge management and education theory, this article demonstrates the role of foreign assignments in the transfer of tacit knowledge in universities with offshore campuses. Research limitations/implications: The implications of the proposition raised in this article are presented with a focus on how they affirm the need for foreign assignments for effective knowledge management in internationalizing universities. Those implications include the need to use assignments to deliver courses offshore and to create face-to-face interactions with academics at partner universities. Originality/value: Drawing on a diverse body of academic literature, this article provides theoretical and practical insights into how assignments can be utilized in international educational management, international educational delivery, and the creation of an environment in which knowledge resources can be utilized on an international basis. © Emerald Group Publishing Limited.

Purpose
– The purpose of this paper is to investigate the performance of natural Jordanian zeolite tuff to remove ammonia from aqueous solutions using a laboratory batch method and fixed-bed column apparatus. Equilibrium data were fitted to Langmuir and Freundlich models.

Design/methodology/approach
– Column experiments were conducted in packed bed column. The used apparatus consisted of a bench-mounted glass column of 2.5 cm inside diameter and 100 cm height (column volume = 490 cm3). The column was packed with a certain amount of zeolite to give the desired bed height. The feeding solution was supplied from a 30 liter plastic container at the beginning of each experiment and fed to the column down-flow through a glass flow meter having a working range of 10-280ml/min.

Findings
– Ammonium ion exchange by natural Jordanian zeolite data were fitted by Langmuir and Freundlich isotherms. Continuous sorption of ammonium ions by natural Jordanian zeolite tuff has proven to be effective in decreasing concentrations ranging from 15-50 mg NH4-N/L down to levels below 1 mg/l. Breakthrough time increased by increasing the bed depth as well as decreasing zeolite particle size, solution flow-rate, initial NH4+ concentration and pH. Sorption of ammonium by the zeolite under the tested conditions gave the sorption capacity of 28 mg NH4-N/L at 20°C, and 32 mg NH4-N/L at 30°C.

Originality/value
– This research investigates the performance of natural Jordanian zeolite tuff to remove ammonia from aqueous solutions using a laboratory batch method and fixed-bed column apparatus. The equilibrium data of the sorption of Ammonia were plotted by using the Langmuir and Freundlich isotherms, then the experimental data were compared to the predictions of the above equilibrium isotherm models. It is clear that the NH4+ ion exchange data fitted better with Langmuir isotherm than with Freundlich model and gave an adequate correlation coefficient value.

Purpose
– The aim of this paper is to contribute to understanding the nature of specialist and generalist human capital by exploring the ways in which knowledge workers view their experience of working in specialist and generalist roles in pharmaceutical firms in Ireland and the UK.

Design/methodology/approach
– The findings are based on interviews with 55 knowledge workers employed in a range of scientific, technical and managerial positions in four Irish and two UK firms located in the pharmaceutical sector. Interviews were also conducted with nine human resource/training and development managers within these six firms.

Findings
– The findings suggest that the categorisation of human capital as either specialist or generalist is too rigid and does not take account of the fact that individuals may themselves choose to shape their careers by investing in a range of education, training and development opportunities that will enable them to move between specialist and generalist roles.

Originality/value
– The paper unpacks the concepts of specialist and generalist human capital from an employee perspective and challenges the sharp distinction that is made between specialist and generalist human capital.

Purpose This chapter explores the ideas of Alasdair MacIntyre and Vaclav Havel and what these two thinkers can contribute to green political theory. Design/methodology/approach This chapter includes examination of some of the key works of Havel and MacIntyre and analysis of these works from the point of view of green political theory. Findings The section ‘Havel and the Imperative to “Live in Truth”: Dissent and Green Politics’ explores Havel’s thought with a particular emphasis on his ethicised notion of political action and critique (‘living in truth’) and his focus on the centrality of dissent (both intellectually and in practice) as central to political critique and action. The section ‘MacIntyre as a Green Thinker: Vulnerability in Political and Moral Theory’ offers an overview of MacIntyre interpreted as a putative green thinker, with a particular emphasis on his ideas of dependence and vulnerability. The Conclusion attempts to draw some common themes together from both thinkers in terms of what they have to offer contemporary green political thought. Research limitations/implications What is presented here is introductory, ground clearing and therefore necessarily suggestive (as well as under-developed). That is, it is the start of a new area of exploration rather than an analysis based on any exhaustive and comprehensive knowledge of both thinkers. Practical implications This chapter offers some initial lines of exploration for scholars interested in the overlap between green thinking and the work of Havel and MacIntyre. Originality/value This is the first exploration of the connections between the works of Havel and MacIntyre and green political theory.

Purpose – Under investigation is Prosecco wine, a sparkling white wine from North-East Italy.
Information collection on consumer perceptions is particularly relevant when developing market
strategies for wine, especially so when local production and certification of origin play an important
role in the wine market of a given district, as in the case at hand. Investigating and characterizing the
structure of preference heterogeneity become crucial steps in every successful marketing strategy. The
purpose of this paper is to investigate the sources of systematic differences in consumer preferences.
Design/methodology/approach – The paper explores the effect of inclusion of answers to
attitudinal questions in a latent class regression model of stated willingness to pay (WTP) for this
specialty wine. These additional variables were included in the membership equations to investigate
whether they could be of help in the identification of latent classes. The individual specific WTPs from
the sampled respondents were then derived from the best fitting model and examined for consistency.
Findings – The use of answers to attitudinal question in the latent class regression model is found to
improve model fit, thereby helping in the identification of latent classes. The best performing model
obtained makes use of both attitudinal scores and socio-economic covariates identifying five latent
classes. A reasonable pattern of differences in WTP for Prosecco between CDO and TGI types were
derived from this model.
Originality/value – The approach appears informative and promising: attitudes emerge as
important ancillary indicators of taste differences for specialty wines. This might be of interest per se
and of practical use in market segmentation. If future research shows that these variables can be of use
in other contexts, it is quite possible that more attitudinal questions will be routinely incorporated in
structural latent class hedonic models.
