Relational work in synchronous text-based CMC of virtual teams

Based on close examinations of instant message (IM) interactions, this chapter argues that an interactional sociolinguistic approach to computer-mediated language use could provide explanations for phenomena that previously could not be accounted for in computer-mediated discourse analysis (CMDA). Drawing on the theoretical framework of relational work (Locher, 2006), the analysis focuses on non-task oriented talk and its function in forming and establishing communication norms in the team, as well as micro-level phenomena, such as hesitation, backchannel signals and emoticons. The conclusions of this preliminary research suggest that the linguistic strategies used for substituting audio-visual signals are strategically used in discursive functions and have an important role in relational work

Advances in femtosecond micromachining and inscription of micro and nano photonic devices

This thesis has focused on three key areas of interest for femtosecond micromachining and inscription. The first area is micromachining where the work has focused on the ability to process highly repeatable, high precision machining with often extremely complex geometrical structures with little or no damage. High aspect ratio features have been demonstrated in transparent materials, metals and ceramics. Etch depth control was demonstrated especially in the work on phase mask fabrication. Practical chemical sensing and microfluidic devices were also fabricated to demonstrate the capability of the techniques developed during this work. The second area is femtosecond inscription. Here, the work has utilised the non-linear absorption mechanisms associated with femtosecond pulse-material interactions to create highly localised refractive index changes in transparent materials to create complex 3D structures. The techniques employed were then utilised in the fabrication of Phase masks and Optical Coherence Tomography (OCT) phantom calibration artefacts both of which show the potential to fill voids in the development of the fields. This especially the case for the OCT phantoms where there exists no previous artefacts of known shape, allowing for the initial specification of parameters associated with the quality of OCT machines that are being taken up across the world in industry and research. Finally the third area of focus was the combination of all of the techniques developed through work in planar samples to create a range of artefacts in optical fibres. The development of techniques and methods for compensating for the geometrical complexities associated with working with the cylindrical samples with varying refractive indices allowed for fundamental inscription parameters to be examined, structures for use as power monitors and polarisers with the optical fibres and finally the combination of femtosecond inscription and ablation techniques to create a magnetic field sensor with an optical fibre coated in Terfenol-D with directional capability. Through the development of understanding, practical techniques and equipment the work presented here demonstrates several novel pieces of research in the field of femtosecond micromachining and inscription that has provided a broad range of related fields with practical devices that were previously unavailable or that would take great cost and time to facilitate.

'Girls who do Boys like they’re girls'? Exploring the role of gender in the junior management of contemporary service work

This article attempts to explain the clustering of women managers at junior managerial grades in the service sector by focusing on the structuring and organization of work in a call centre. The article is based on an ethnography of an organization and seeks to contribute to the ongoing debate in gender research by exploring and documenting the requirement for the enactment of masculinities at work for successful managers. Central to our account is the role of team leader which, as a junior management position, occupies a key role in understanding and accounting for the gendered hierarchical terrain of contemporary service-based organizations. In exploring the role of team leader, a position that tends overwhelmingly to be held by female staff, we draw attention to the perception of the gendered nature of the role by subordinate members of the organization, the team-leaders themselves and more senior managers. The position is also brought into sharp relief in comparison with the subordinate role of the ‘problem manager’, a position overwhelmingly held by men.

Strategic and operational risk in an international collaboration agency: a knowledge management solution

The International Cooperation Agency (identified in this article as IDEA) working in Colombia is one of the most important in Colombian society with programs that support gender rights, human rights, justice and peace, scholarships, aboriginal population, youth, afro descendants population, economic development in communities, and environmental development. The identified problem is based on the diversified offer of services, collaboration and social intervention which requires diverse groups of people with multiple agendas, ways to support their mandates, disciplines, and professional competences. Knowledge creation and the growth and sustainability of the organization can be in danger because of a silo culture and the resulting reduced leverage of the separate group capabilities. Organizational memory is generally formed by the tacit knowledge of the organization members, given the value of accumulated experience that this kind of social work implies. Its loss is therefore a strategic and operational risk when most problem interventions rely on direct work in the socio-economic field and living real experiences with communities. The knowledge management solution presented in this article starts first, with the identification of the people and groups concerned and the creation of a knowledge map as a means to strengthen the ties between organizational members; second, by introducing a content management system designed to support the documentation process and knowledge sharing process; and third, introducing a methodology for the adaptation of a Balanced Scorecard based on the knowledge management processes. These three main steps lead to a knowledge management “solution” that has been implemented in the organization, comprising three components: a knowledge management system, training support and promotion of cultural change.

Real-time process plant fault diagnosis

Operators can become confused while diagnosing faults in process plant while in operation. This may prevent remedial actions being taken before hazardous consequences can occur. The work in this thesis proposes a method to aid plant operators in systematically finding the causes of any fault in the process plant. A computer aided fault diagnosis package has been developed for use on the widely available IBM PC compatible microcomputer. The program displays a coloured diagram of a fault tree on the VDU of the microcomputer, so that the operator can see the link between the fault and its causes. The consequences of the fault and the causes of the fault are also shown to provide a warning of what may happen if the fault is not remedied. The cause and effect data needed by the package are obtained from a hazard and operability (HAZOP) study on the process plant. The result of the HAZOP study is recorded as cause and symptom equations which are translated into a data structure and stored in the computer as a file for the package to access. Probability values are assigned to the events that constitute the basic causes of any deviation. From these probability values, the a priori probabilities of occurrence of other events are evaluated. A top-down recursive algorithm, called TDRA, for evaluating the probability of every event in a fault tree has been developed. From the a priori probabilities, the conditional probabilities of the causes of the fault are then evaluated using Bayes' conditional probability theorem. The posteriori probability values could then be used by the operators to check in an orderly manner the cause of the fault. The package has been tested using the results of a HAZOP study on a pilot distillation plant. The results from the test show how easy it is to trace the chain of events that leads to the primary cause of a fault. This method could be applied in a real process environment.

The management of diversification in a large industrial company

This work is the result of an action-research-type study of the diversification effort of part of a major U.K. industrial company. Work in contingency theory concerning the impact of environmental factors on organizational design, and the systemic model of viable systems put forward by Stafford Beer form the theoretical basis of the vvork. The two streams of thought are compared and found to offer similar conclusions about the design of effective organizations. These findings are taken as the framework for an analysis both of organization structures for promoting innovation described in the literature, and of those employed by the company for this purpose in recent years. Much attention is given to the use of venture groups, and conclusions are drawn on particular factors which may influence their success or failure. Both theoretical considerations, and the examination of the company' s recent experience suggested that the formation of the policy of diversification, as well as the method of implementation of the police, might affect its outcorre. Attention is therefore focused on the policy-making and planning process, and in particular on possible problems that this process could generate in a multi-division company. The view finally taken of diversification effort is that it should be regarded as a learning system. This view helps to expose some ambiguities in the concepts of success and failure in this area, and demonstrates considerable weaknesses in traditional project evaluation procedures.

Technical change and work organisation

This thesis is an exploration of the social and political processes involved in the introduction of new technology to the shopfloor. Through a series of case studies of applications of microelectronics to batch manufacture, it attempts to uncover the ways in which the values and interests of managers, engineers, workers and others profoundly influence the choice and use of technology, and thus the work organisation which emerges. Previous analyses have tended to treat new technology as if it had "impacts" on work organisation - especially skills - which are inevitable in particular technical and economic circumstances. It is in opposition to this view that technical change is here treated as a matter for social choice and political negotiation, the various interested parties to the change being shown to attempt to incorporate their own interests into the technical and social organisation of work. Section one provides the relevant background to the case studies by summarising and criticising previous theoretical and empirical work in the area. The inadequacies of this work for our concerns are drawn out, and the need for detailed studies of the political aspects of technical change is justified. The case studies are presented in section two as a set of "episodes" of innovation, and section three analyses the empirical findings. The innovations are compared and contrasted in order to illustrate the social and political dynamics involved in the various stages of the innovation process. Finally some comments are made on policy issues for which the research has important implications.

Stakeholders' perceptions of corporate social reporting in Bangladesh

Recent calls in the corporate social reporting (CSRep) literature have emphasized the importance of giving voice to non-managerial stakeholder groups in the social reporting process. The research, presented in this paper, employs recent work in stakeholder theory and CSRep to examine the perceptions of a diverse set of non-managerial stakeholders in the context of a developing country, Bangladesh. A series of semi-structured interviews were conducted with individuals who identify with various non-managerial stakeholder groups. Interviewees generally believed that the motivation and practice of CSRep in Bangladesh is developing in response to pressures from international markets and is producing largely cosmetic responses. Also, they expressed concerns that, given the economic, political, and social conditions in Bangladesh, premature adoption of strict CSRep standards may lead to increased corruption and other unintended consequences. Whilst some of the interviewees sharply criticized the current process of imposing social accounting codes/standards on developing countries which fail to consider the important local socio-economic context, the findings suggest that there is overwhelming support for mandatory externally verified CSRep based on the principles of peoples' right to know, full disclosure/completeness, and relevance, which are anchored in the broader principles of transparency and stakeholder accountability. © 2010 Springer Science+Business Media B.V.

Process and performance in international collaborative research

Motivated by policy goals to develop international research capability and our experiences of collaborative research, we wanted to learn more about the factors that influence success in collaborative research. This article presents a review of the academic literature on collaborative research, focusing on multinational teams doing international comparative research. We address the question ‘what accounts for variation in process and performance of collaborative research projects?’, through 11 themes: context; vision; reward and commitment; leadership; structure; contract; task capability; sociability; communication; finance; rhythm and pace. We then propose an agenda for future research with an analytic framework and, finally, our conclusions.

Characterisation of ICAM-3 and extracellular vesicles in the clearance of apoptotic cells

Apoptotic cell clearance by phagocytes is a vital part of programmed cell death that prevents dying cells from undergoing necrosis which may lead to inflammatory and autoimmune disorders. Apoptotic cells (AC) are removed by phagocytes, in a process that involves 'find me' and 'eat me' signals that facilitate the synapsing and engulfment of cell corpses. Extracellular vesicles (EV) are shed during apoptosis and promote phagocyte recruitment. Binding of AC is achieved by multiple ligand-receptor interactions. One interesting AC associated ligand is ICAM-3, a highly glycosylated adhesion molecule of the IgSF family, expressed on human leukocytes. On viable cells ICAM-3 participates in initiating immune responses, whereas on AC we show it attracts phagocytes through EV and aids in the binding of AC to the phagocytes. This project aims to characterize the role of ICAM-3 and EV in the clearance of AC and to identify the mechanisms that underlie their function in apoptotic cell clearance. Human B cells induced to apoptosis by UV irradiation were observed during their progression from viable to apoptotic via flow cytometry. The involvement of ICAM-3 in mediating interaction between AC and MØ was assessed. The ability of ICAM3 on EV to mediate chemoattraction was observed using chemotaxis assays. Additionally the anti-inflammatory effect was assessed using LPS-induced TNF-α production that suggested it may have anti-inflammatory effects. Future work in this project will assess the role of ICAM3 on EV from different phases of apoptosis to exert functional effects both in vitro and in vivo.

Measures of process harmonization

Context Many large organizations juggle an application portfolio that contains different applications that fulfill similar tasks in the organization. In an effort to reduce operating costs, they are attempting to consolidate such applications. Before consolidating applications, the work that is done with these applications must be harmonized. This is also known as process harmonization. Objective The increased interest in process harmonization calls for measures to quantify the extent to which processes have been harmonized. These measures should also uncover the factors that are of interest when harmonizing processes. Currently, such measures do not exist. Therefore, this study develops and validates a measurement model to quantify the level of process harmonization in an organization. Method The measurement model was developed by means of a literature study and structured interviews. Subsequently, it was validated through a survey, using factor analysis and correlations with known related constructs. Results As a result, a valid and reliable measurement model was developed. The factors that are found to constitute process harmonization are: the technical design of the business process and its data, the resources that execute the process, and the information systems that are used in the process. In addition, strong correlations were found between process harmonization and process standardization and between process complexity and process harmonization. Conclusion The measurement model can be used by practitioners, because it shows them the factors that must be taken into account when harmonizing processes, and because it provides them with a means to quantify the extent to which they succeeded in harmonizing their processes. At the same time, it can be used by researchers to conduct further empirical research in the area of process harmonization.

Expert report writing in toxicology:forensic, scientific and legal aspects

Every year throughout the world, individuals' health is damaged by their exposure to toxic chemicals at work. In most cases these problems will resolve, but many will sustain permanent damage. Whilst any justified claim for compensation requires medical and legal evidence a crucial and often controversial component of this process is the establishment of a causal link between the individual's condition and exposure to a specific chemical or substance. Causation, in terms of how a substance or substances led the claimant to his or her current plight, can be difficult to establish and the main purpose of this book, is to provide the aspiring expert report writer with a concise, practical guide that uses case histories to illuminate the process of establishing causation in occupational toxicity proceedings. In summary: A practical, accessible guide to the preparation of balanced, scientifically sound expert reports in the context of occupational toxicology. Focuses on the scientist's role in establishing a causal link between exposure to toxins and an individual's ill health. Includes real-life case histories drawn from the Author's 15 years experience in this area to illustrate the principles involved. Expert Report Writing in Toxicology: Forensic, Scientific and Legal Aspects proves invaluable to scientists across a range of disciplines needing guidance as to what is expected of them in terms of the best use of their expertise and how to present their findings in a manner that is authoritative, balanced and informative.

Reconstructing institutional complexity in practice:a relational model of institutional work and complexity

This article develops a relational model of institutional work and complexity. This model advances current institutional debates on institutional complexity and institutional work in three ways. First, it provides a relational and dynamic perspective on institutional complexity by explaining how constellations of logics - and their degree of internal contradiction - are constructed rather than given. Second, it refines our current understanding of agency, intentionality and effort in institutional work by demonstrating how different dimensions of agency interact dynamically in the institutional work of reconstructing institutional complexity. Third, it situates institutional work in the everyday practice of individuals coping with the institutional complexities of their work. In doing so, it reconnects the construction of institutionally complex settings to the actions and interactions of the individuals who inhabit them. © The Author(s) 2013.

Networked gentrification:placemaking strategies and social networks of middle class gentrifiers in Istanbul

This chapter explores how gentrifiers in Istanbul mobilise their social networks and social capital during the gentrification process, and how their networks are constructed through processes of “ place making” and belonging. In addition, this chapter aims to demonstrate how social capital and social networks work in practice during the gentrification process. It also examines place making and claiming strategies of gentrifiers by focusing on the following questions: (a) What are the spatial strategies of the new middle class, and what is the importance of these strategies?; (b) How are class and spatial boundaries designated in gentrified neighbourhoods?; (c) What kinds of networks and relationships play a role in developing certain housing dispositions or belonging patterns
