360-degree feedback from a variety of rater sources yields important information about leaders' styles, strengths and weaknesses for development. Results where observer ratings are discrepant (i.e., different) from self-ratings are often seen as indicators of problematic leadership relationships, skills, or lack of self-awareness. Yet research into the antecedents of such self-observer rating discrepancy suggests the presence of systematic influences, such as cultural values. The present study investigates the variation of rating discrepancies on three leadership skills (decision making, leading employees, and composure) in dependence of one exemplary culture dimension (power distance) on data from 31 countries using multilevel structural equation modelling. Results show that cultural values indeed predict self-observer rating discrepancies. Thus, systemic and contextual influences such as culture need to be taken into consideration when interpreting the importance and meaning of self-observer rating discrepancies in 360-degree instruments.

There is now substantial evidence that locational and agglomeration influences can have a significant positive effect on innovation performance. Networking and boundary-spanning activities are also increasingly recognised as important contributors to innovation success. In this article we attempt to discover whether these factors are associated: in particular, is there any link between plant location, agglomeration effects and the extent of outsourcing in the innovation process? Using data for a large sample of UK and German manufacturing plants, we find that organisational and strategic factors play a much greater and more consistent role than locational influences in shaping the level of outsourcing in the innovation process. Strategic approaches to outsourcing may also benefit plants in obtaining economies of scope in the management or governance of outsourcing within the innovation process.

Recent developments in the new economic geography and the literature on regional innovation systems have emphasised the potentially important role of networking and the characteristics of firms' local operating environment in shaping their innovative activity. Modeling UK, German and Irish plants' investments in R&D, technology transfer and networking, and their effect on the extent and success of plants' innovation activities, casts some doubt on the importance of both of these relationships. In particular, our analysis provides no support for the contention that firms or plants in the UK, Ireland or Germany with more strongly developed external links (collaborative networks or technology transfer) develop greater innovation intensity. However, although inter-firm links also have no effect on the commercial success of plants' innovation activity, intra-group links are important in terms of achieving commercial success. We also find evidence that R&D, technology transfer and networking inputs are substitutes rather than complements in the innovation process, and that there are systematic sectoral and regional influences in the efficiency with which such inputs are translated into innovation outputs. © 2001 Elsevier Science B.V.

The opening up of the Chinese economy and the associated transfer of technology from abroad have been taking place at an accelerating pace. Technology is crucial to China's industrial development. It is a productive resource and has a vital role in the process of economic and social development. This article provides an overview of technology transfer into China, focusing on recent developments, and examines the macroenvironmental and microenvironmental influences which foreign enterprises must consider when making investments or technology transfer decisions. Cases of companies engaged in international technology transfer are used to illustrate the discussion on the microenvironment. To be successful, foreign investors and suppliers of technology must respond to China's industrial priorities and pursue projects that are compatible with the country's broad policy goals as well as the corporate objectives of Chinese partners. The article concludes by listing a number of points to which attention should be paid before a decision is made to transfer technology to China.

The adjuvant efficacy of cationic liposomes composed of dimethyldioctadecylammonium bromide and trehalose dibehenate (DDA:TDB) is well established. Whilst the mechanism behind its immunostimulatory action is not fully understood, the ability of the formulation to promote a 'depot effect' is a consideration. The depot effect has been suggested to be primarily due to their cationic nature which results in electrostatic adsorption of the antigen and aggregation of the vesicles at the site of injection. The aim of the study was to further test this hypothesis by investigating whether sterically stabilising DDA:TDB with polyethylene glycol (PEG) reduces aggregation, and subsequently influences the formation of a depot at the site of injection. Results reported demonstrate that high (25%) levels of PEG was able to significantly inhibit the formation of a liposome depot and also severely limit the retention of antigen at the site, resulting in a faster drainage of the liposomes from the site of injection. This change in biodistribution profile was reflected in the immunisation response, where lower levels of IgG2b antibody and IFN-? and higher level of IL-5 cytokine were found. Furthermore entrapping antigen within DDA:TDB liposomes did not improve antigen retention at the injection site compared surface adsorbed antigen. © 2011 Elsevier B.V. All rights reserved.

Purpose – The purpose of this paper is to examine students’ perceptions of managerial mistakes and why (and why not) managers admit mistakes. Design/methodology/approach – This paper provides a reflective account of how students’ perceive management mistakes and deal with admitting “mea culpa” – “I am to blame”. Findings – The findings show a range of attitudes: they highlight the intermingling pressures associated with the cultural environment and mistakes; they identify media characteristics and its influences on mistakes and mea culpa; they highlight ceremonial processes and tasks that shape and influence the declaration of mea culpa; and they identify how the psychology and sociology of mistakes confronts and affects students. Taken together, the study highlights the varying degrees of wariness that is carried forward by the students from vicariously learning about management mistakes. Originality/value – This paper links up with recent discussions on retail failure and retail pedagogy. It is hoped that this paper will encourage more academics to address, and engage with, management mistakes creatively in their teaching.

Investigations of relationships between the specific personality variable, locus of control (LOC, Rotter, 1966) and driver behaviour or accidents have returned contrasting results. Review suggests dependence on gender or experience characteristics of participants, suggesting these factors interact with LOC to influence driving. Relationships were investigated in terms of influence on the eight driving styles of the Multidimensional Driving Style Inventory (MDSI, Taubman-Ben-Ari, Mikulincer & Gillarth, 2004) in young drivers (18-29 years). Gender and LOC differences in driving styles previously related to accidents were proposed. It was also proposed that driving experience influences driving style, and LOC influences effect of driving experience. Gender differences were found for dissociative, anxious, patient, risky, angry and high velocity styles. Women had more external LOC than men, and driver stress styles increased with more external LOC, but reduced with increased driving experience, but so did patient style. High velocity style increased with experience. Controlling for LOC revealed important gender differences in effect of experience: positive effects for men (reducing angry and high velocity, increasing carefulness) and negative effects for women (increasing angry and higher velocity, reducing carefulness). Findings suggest negative influence of high internal LOC on young men in terms of its interaction with experience.

Customer-oriented boundary-spanning behaviours (COBSBs) are critical to the success of service organisations. Transformational leadership, with its emphasis on the social elements of the leader-subordinate dyad, is a likely antecedent to COBSBs. Similarly, the interpersonal nature of services suggests leader compassion could have a significant effect on the saliency of the relationship between transformational leadership and COBSBs. This paper reports on a study of the moderating effect of leader compassion on the relationship between transformational leadership and COBSBs (service delivery behaviours, internal influence and external representation). Transformational leadership and compassion both have significant and positive influences on COBSBs. However, compassion plays no moderating role. These findings are discussed and avenues for further research are proposed.

This paper builds on Granovetter's distinction between strong and weak ties [Granovetter, M. S. 1973. The strength of weak ties. Amer. J. Sociol. 78(6) 1360–1380] in order to respond to recent calls for a more dynamic and processual understanding of networks. The concepts of potential and latent tie are deductively identified, and their implications for understanding how and why networks emerge, evolve, and change are explored. A longitudinal empirical study conducted with companies operating in the European motorsport industry reveals that firms take strategic actions to search for potential ties and reactivate latent ties in order to solve problems of network redundancy and overload. Examples are given, and their characteristics are examined to provide theoretical elaboration of the relationship between the types of tie and network evolution. These conceptual and empirical insights move understanding of the managerial challenge of building effective networks beyond static structural contingency models of optimal network forms to highlight the processes and capabilities of dynamic relationship building and network development. In so doing, this paper highlights the interrelationship between search and redundancy and the scope for strategic action alongside path dependence and structural influences on network processes.

This paper explores how regulatory relationships in the global audit arena are being affected by the current financial crisis. Key policy initiatives and debates are analyzed, along with institutional interactions, in particular between the International Federation of Accountants (IFAC), international regulators and the large audit firms. The events are placed in the context of the new international financial architecture which has developed over the last decade. Using the illustrative lens of bank auditing, questions are asked of the nature and status of audit practice and the regulatory arrangements governing such practice. The paper shows the active nature of the regulatory responses to the crisis and the shifting and competing influences among key regulatory and professional participants in the global audit arena. Emphasis is placed on the need for audit researchers to be sensitive to the developing global financial architecture, and its potential implications for the study of audit practice in different national and international contexts.

Food allergy affects 6% of children but there is no cure, and strict avoidance of index allergens along with immediate access to rescue medication is the current best management. With specialist care, morbidity from food allergy in children is generally low, and mortality is very rare. However, there is strong evidence that food allergy and food hypersensitivity has an impact on psychological distress and on the quality of life (QoL) of children and adolescents, as well as their families. Until recently, the measurement of QoL in allergic children has proved difficult because of the lack of investigative tools available. New instruments for assessing QoL in food allergic children have recently been developed and validated, which should provide further insights into the problems these children encounter and will enable us to measure the effects of interventions in patients. This review examines the published impact of food allergy on affected children, adolescents and their families. It considers influences such as gender, age, disease severity, co-existing allergies and external influences, and examines how these may impact on allergy-related QoL and psychological distress including anxiety and depression. Implications of the impact are considered alongside avenues for future research.

The appealing feature of the arbitrage-free Nelson-Siegel model of the yield curve is the ability to capture movements in the yield curve through readily interpretable shifts in its level, slope or curvature, all within a dynamic arbitrage-free framework. To ensure that the level, slope and curvature factors evolve so as not to admit arbitrage, the model introduces a yield-adjustment term. This paper shows how the yield-adjustment term can also be decomposed into the familiar level, slope and curvature elements plus some additional readily interpretable shape adjustments. This means that, even in an arbitrage-free setting, it continues to be possible to interpret movements in the yield curve in terms of level, slope and curvature influences. © 2014 © 2014 Taylor & Francis.
