Although the existence of halogenated lipids in lower organisms has been known for many years, it is only since the 1990s that interest in their occurrence in mammalian systems has developed. Chlorinated (and other halogenated) lipids can arise from oxidation by hypohalous acids, such as HOCl, which are products of the phagocytic enzyme myeloperoxidase and are generated during inflammation. The major species of chlorinated lipids investigated to date are chlorinated sterols, fatty acid and phospholipid chlorohydrins, and a-chloro fatty aldehydes. While all of these chlorinated lipids have been shown to be produced in model systems from lipoproteins to cells subjected to oxidative stress, as yet only a-chloro fatty aldehydes, such as 2-chlorohexadecanal, have been detected in clinical samples or animal models of disease. a-Chloro fatty aldehydes and chlorohydrins have been found to have a number of potentially pro-inflammatory effects ranging from toxicity to inhibition of nitric oxide synthesis and upregulation of vascular adhesion molecules. Thus evidence is building for a role of chlorinated lipids in inflammatory disease, although much more research is required to establish the contributions of specific compounds in different disease pathologies. Preventing chlorinated lipid formation and indeed other HOCl-induced damage, via the inhibition of myeloperoxidase, is an area of growing interest and may lead in the future to antimyeloperoxidase-based antiinflammatory therapy. However, other chlorinated lipids, such as punaglandins, have beneficial effects that could offer novel therapies for cancer.

At the beginning of the 80s new approaches to translation were emerging in such a way that, in the global context of postmodernism and poststructuralism, they provoked a reassessment of Translation Studies (TS), acknowledging ideologies as a relevant concept to TS and considering the political and visible role of the translator. This introduction aims to establish a basic theoretical framework in which we can develop an analysis of the ‘alterations’ that, consciously or unconsciously, translators have imposed on Le deuxième sexe (1949, Gallimard) by Simone de Beauvoir for the last fifty years. Furthermore, it is essential to examine the divergences of the censoring attitude adopted by the first male translators (Parshley, Palant and Milliet) who considered this text to be a sex manual, and the one adopted by more recent female translators (Martorell and Simons) who considered it to be a philosophical book on feminism. Nevertheless, despite this tendency to consider that translators are the only professionals responsible for the translation process, it is necessary to bear in mind the work carried out by the paratranslator, who is the real censor and ‘decider’ of the way a work is presented to the translation community. Paratranslators work with paratexts (also known as ‘analysis-spaces’), and this makes it possible to study the ideological adaptation that a cultural object undergoes when it is incorporated into a new culture and society (covers, volumes, tables of contents, titles, iconic or visual elements and so forth). In short, the analysis of the texts and paratexts of Le deuxième sexe, along with its subsequent translations and rewritings into Spanish, Portuguese and English, will help reveal the function of the censoring apparatus and demonstrate the essential role that –without exception– ideologies play in the professional work of translation and paratranslation, since they have a decisive influence on the reception of the cultural (and ideological) object, in both the society in which it is created and that in which it is received.

Extant research on the impact of privatization in the Central Europe (CE) region has focused on improvements in efficiency and the nature of cost-based advantages. This study argues that the development of a vibrant privatized sector requires attention to the broader resource configurations of domestic enterprises. Empirical research was conducted on a large sample of firms in Poland, Hungary and Slovenia. Foreign investment was found to significantly impact on resource accumulation with implications for the development of strategic capabilities and competitive advantage. Foreign direct investment is an effective vehicle for the transfer of financial resources, reputation and new brands but not organizational capabilities. In terms of practice, this study demonstrates the important role of outside investment in the development of a firm's resource base (Frydman et al. 1999). Companies can gain a competitive advantage in their domestic markets through gaining access to the resources of foreign investors.

Much recent scholarship concerning liberalization has emphasized the role of regulatees, rather than governments, in promoting liberalization. This article examines such scholarship in the light of an important development in the British and French public sectors—the creation of new agencies (the Education Counselling Service and EduFrance) to ‘sell’ British and French higher education to potential international students. The new agencies attempted to induce two things: competition amongst higher education institutions for the recruitment of international students from developed and emerging economy countries, and the commodification of these students. This article shows that, contrary to existing theories of liberalization, governments were pre-eminent in pushing forward this liberalization, while higher education institutions attempted to hold it back.

This thesis examines the possibility of privatising public owned five star hotels in Egypt through its stock market in order to give a boost to the Egyptian privatisation programme and to help activate its stock market. To explore these aspects, two main technical exercises were executed. First the writer constructed, for the first time in Egypt, a daily price index for Cairo Stock Exchange and an index for the tourism sector, in order to analyze the efficiency of the capital market. This technical analysis showed that Cairo stock exchange is inefficient, stagnant and undergoes minimal fluctuations, especially when compared to other developed and emerging markets. Second, given the importance and complexity of the valuation of SOEs prior to their privatisation, a sample of three five star hotels that could be prime candidates for privatisation via the stock market in Egypt were selected and a detailed financial analysis for the three hotels was concluded. The result was a valuation range for the three hotels using various valuation methods. Nevertheless it was found out that the final value of hotels will be determined by the market itself. Depite the inefficiency of Cairo Stock Exchange, the thesis did not rule out privatisation through the stock market. On the contrary it cited several examples of developing countries that were able to successfully privatise some of their SOEs via their rudimentary capital markets. Finally, the thesis recommended that five star hotels could be pefect candidates for privatisation via the stock market in Egypt. This is because five star hotels are profitable, privately managed, non strategic and not highly capital intensive businesses. In addition, they do not suffer from overstaffing and the industry in which they operate i.e. tourism sector, has high growth prospects and is of an international nature. Therefore it is anticipated that privatisation of five star hotels can attract a lot of investors because of the relatively high returns. This in turn will help activate and popularize the capital market in Egypt. At the same time the benefits of privatisation would be more visible which will give more momentum to the privatisation programme and make it more politically acceptable.

It is now stylized that the importance of foreign direct investment for developing countries and emerging markets arises from the impact of the presence of multinational corporations (MNCs) in the host country on the productivity of local firms, by way of technology diffusion and competition. There is also general agreement that the extent of technology transfer by an MNC to a developing country affiliate depends on the extent of its control on the local affiliate and that, in turn, the extent of this control depends on the mode of entry of the MNC into the host country. However, the existing literature is based on the experience of developed countries and as such does not contribute to the literature on development economics. This article addresses this lacuna using unique firm-level data from South Africa and Egypt. Our results indicate that the determinants of entry mode choice not only differ between developed and developing countries, but also among developing countries. They also bring into question the role of MNCs in fostering productivity growth in developing countries.

There appears to be a missing dimension in OL literature to embrace the collective experience of emotion, both within groups and communities and also across the organization as a whole. The concept of OL efficacy- as a stimulus offering energy and direction for learning - remains unexplored. This research involved engaging with a company we have called ‘Electroco’ in depth to create a rich and nuanced representation of OL and members’ perceptions of OL over an extended time-frame (five years). We drew upon grounded theory research methodology (Locke, 2001), to elicit feedback from the organization, which was then used to inform future research plans and/ or refine emerging ideas. The concept of OL efficacy gradually emerged as a factor to be considered when exploring the relationship between individual learning and OL. . Bearing in mind Bandura’s (1982) conceptualization of self-efficacy (linked with mastery, modelling, verbal persuasion and emotional arousal), we developed a coding strategy encompassing these four factors as conceptualized at the organizational level. We added a fifth factor: ‘control of OL.’ We focused on feelings across the organization and the extent of consensus or otherwise around these five attributes. The construct has potential significance for how people are managed in many ways. Not only is OL efficacy is difficult for competitors to copy (arising as it does from the collective experience of working within a specific context); the self-efficacy concept suggests that success can be engineered with ‘small wins’ to reinforce mastery perceptions. Leaders can signal the importance of interaction with the external context, and encourage reflection on the strategies adopted by competitors or benchmark organizations (modelling). The theory also underlines the key role managers may play in persuading others about their organization’s propensity to learn (by focusing on success stories, for example). Research is set to continue within other sectors, including the high-performance financial service sector as well as the health-care technology sector.

Using firm level data from India, we examine the impact of ownership concentration on post-M&A performance of firms. Our analysis has implications for both the M&A literature, which emphasises the role of agency conflict between managers and owners of widely held companies as a key reason for M&A failures, and the corporate governance literature, especially in the context of emerging market economies. A cautious interpretation of our results suggests that while ownership concentration may reduce the manager–owner agency conflict, it may nevertheless precipitate other forms of agency conflict such that ownership concentration may not necessarily improve post-M&A performance. In particular, our results have implications for the literature on the agency conflict between large (or majority) shareholders and small (or minority) shareholders of a company, especially in contexts such as emerging market economies where corporate governance quality is weak.

The existing body of knowledge has generally supported that organizational culture plays a significant role in shaping group identity, work pattern, communication schemes, and interpersonal relations; all of these cultural elements are important organizational factors that shape workplaces and operational routines. In the context of emerging information technology, it has also been suggested that organizational culture could affect IT implementation and management. However, little is known about how emerging information technology shapes organizational culture, which in turn helps reshape the organization as a whole. The purpose of this paper is thus to build empirical understanding of how IT in general and emerging wireless networks in particular reshapes organizational culture. Case studies conducted in two hospitals situated in southwest U.S.A. illustrated that the implementation of wireless networks indeed helped shape and/or reshape organizational culture in the healthcare sector and in turn enhance healthcare organizations’ competitiveness in the marketplace. For IT managers and practitioners in healthcare institutions, effective strategy to plan and manage emerging ITs such as wireless networks will thus have long-term implications on cultivating organizational culture that could eventually reshape workplace and competitiveness.

We investigate the impact of market-supporting institutions on business strategies by analyzing the entry strategies of foreign investors entering emerging economies. We apply and advance the institution-based view of strategy by integrating it with resource-based considerations. In particular, we show how resource-seeking strategies are pursued using different entry modes in different institutional contexts. Alternative modes of entry—greenfield, acquisition, and joint venture (JV)—allow firms to overcome different kinds of market inefficiencies related to both characteristics of the resources and to the institutional context. In a weaker institutional framework, JVs are used to access many resources, but in a stronger institutional framework, JVs become less important while acquisitions can play a more important role in accessing resources that are intangible and organizationally embedded. Combining survey and archival data from four emerging economies, India, Vietnam, South Africa, and Egypt, we provide empirical support for our hypotheses.

In the wake of this decade's corporate scandals, crimes and excesses, improving the effectiveness of corporate governance in the United States has become a priority. An important influence on a board's effectiveness at monitoring is its members’ degree of independence from senior management. While the current definition of independence revolves around the absence of familial and economic connections between a firm and its directors, research suggests that this standard may be inadequate in ensuring independent oversight. Rather, diversity along racial, gender and other dimensions has been proposed as a potentially more effective standard for board independence. This is especially welcome news for women, who currently comprise 51 per cent of the US managerial workforce but only 14.8 per cent of the directors on boards of large, publicly traded US corporations. Some explain the current dearth of women board members by claiming that there are no qualified women available for board service and/or that women are not interested in board service. However, there is more anecdotal rather than empirical evidence on the issue. Surveying women at a women's leadership conference in Boston, this research investigates the extent to which women are currently involved in some type of board service and the extent to which women aspire to future board service. We find that women are currently more active in governance activities than prior research on corporate boards suggests and that they aspire to play a continued and expanded role in governance activities.

For companies competing in highly dynamic markets, the search for new sources of competitive advantages is mandatory. Innovation is considered a fundamental component of a successful business as it allows companies to sustain profit margins and sales growth and to reduce pressures coming from competitors. In the knowledge-driven economy, information and communication technology (ICT) plays an important role as it enables innovation in product/service, processes and organisations especially in service companies. This paper investigates the role of ICT in logistics innovation. The focus of the paper is on the effects that ICT usage is having on the management of small third-party logistics service providers (3PLs). On the basis of quantitative and qualitative evidence emerging from a recent survey carried out on the Italian logistic service market, the paper analyses how ICT is used to support logistics innovation and the factors inhibiting/facilitate the usage of ICT in such companies. Implications for logistics innovation management will be outlined from both research and managerial perspectives.

Models of Alzheimer’s disease (AD) have provided useful insights into the pathogenesis and mechanistic pathways that lead to its development. One emerging idea about AD is that it may be described as a hypometabolic disorder due to the reduction of glucose uptake in AD brains. Inappropriate processing of Amyloid Precursor Protein (APP) is considered central to the initiation and progression of the disease. Although the exact role of APP misprocessing is unclear, it may play a role in neuronal metabolism before the onset of neurodegeneration. To investigate the potential role of APP in neuronal metabolism, the SHSY5Y neuroblastoma cell line was used to generate cell lines that stably overexpress wild type APP695 or express Swedish mutated-APP observed in familial AD (FAD), both under the control of the neuronal promoter, Synapsin I. The effects of APP on glucose uptake, cellular stress and energy homeostasis were studied extensively. It was found that APP-overexpressing cells exhibited decreased glucose uptake with changes in basal oxygen consumption in comparison to control cell lines. Similar studies were also performed in fibroblasts taken from FAD patients compared with control fibroblasts. Previous studies found FAD-derived fibroblasts displayed altered metabolic profiles, calcium homeostasis and oxidative stress when compared to controls. As such, in this study fibroblasts were studied in terms of their ability to metabolise glucose and their mitochondrial function. Results show that FAD-derived fibroblasts demonstrate no differences in mitochondrial function, or response to oxidative stress compared to control fibroblasts. However, control fibroblasts treated with Aβ1-42 demonstrated changes in glucose uptake. This study highlights the importance of APP expression within non-neuronal cell lines, suggesting that whilst AD is considered a brain-associated disorder, peripheral effects in non-neuronal cell types should also be considered when studying the effects of Aβ on metabolism.

This paper discusses the question of how well prepared Engineering Educators are to implement Active Learning approaches within Higher Education undergraduate Engineering Programmes in Malaysia. As the role of Higher Education has shifted from being that of a 'knowledge provider' to become primarily focused upon 'learning facilitation', so the role of teachers or academic staff has changed in that they have become the key to implementing successful Active Learning. Based upon the emergent findings from a case study conducted at a Malaysian institution of higher education, the paper reveals that the engineering educators within the institution concerned were neither prepared nor ready to implement Active Learning. Indeed, it is evident from the study findings that a huge effort is needed in terms of educational policy and practice to ensure that Malaysian institutions offering engineering education should move efficiently and effectively towards the unilateral adoption of Active Learning approaches.
