Insect pest control research : the analysis of historical trends with special reference to scientometric analysis

The thesis investigates the value of quantitative analyses for historical studies of science through an examination of research trends in insect pest control, or economic entomology. Reviews are made of quantitative studies of science, and historical studies of pest control. The methodological strengths and weaknesses of bibliometric techniques are examined in a special chapter; techniques examined include productivity studies such as paper counts, and relational techniques such as co-citation and co-word analysis. Insect pest control is described. This includes a discussion of the socio-economic basis of the concept of `pest'; a series of classifications of pest control techniques are provided and analysed with respect to their utility for scientometric studies. The chemical and biological approaches to control are discussed as scientific and technological paradigms. Three case studies of research trends in economic entomology are provided. First a scientometric analysis of samples of chemical control and biological control papers; providing quantitative data on institutional, financial, national, and journal structures associated with pest control research fields. Second, a content analysis of a core journal, the Journal of Economic Entomology, over a period of 1910-1985; this identifies the main research innovations and trends, in particular the changing balance between chemical and biological control. Third, an analysis of historical research trends in insecticide research; this shows the rise, maturity and decline of research of many groups of compounds. These are supplemented by a collection of seven papers on scientometric studies of pest control and quantitative techniques for analysing science.

Designing mobile technologies for individuals with disabilities

While mobile devices offer many innovative possibilities to help increase the standard of living for individuals with disabilities and other special needs, the process of developing assistive technology, such that it will be effective across a group of individuals with a particular disability, can be extremely challenging. This chapter discusses key issues and trends related to designing and evaluating mobile assistive technology for individuals with disabilities. Following an overview of general design process issues, we argue (based on current research trends) that individuals with disabilities and domain experts be involved throughout the development process. While this, in itself, presents its own set of challenges, many strategies have successfully been used to overcome the difficulties and maximize the contributions of users and experts alike. Guidelines based on these strategies are discussed and are illustrated with real examples from one of our active research projects.

Combining an enterprise resource planning system and informality:a study of efficiency and flexibility complmentarity [sic]

DUE TO COPYRIGHT RESTRICTIONS ONLY AVAILABLE FOR CONSULTATION AT ASTON UNIVERSITY LIBRARY AND INFORMATION SERVICES WITH PRIOR ARRANGEMENT One of the current research trends in Enterprise Resource Planning (ERP) involves examining the critical factors for its successful implementation. However, such research is limited to system implementation, not focusing on the flexibility of ERP to respond to changes in business. Therefore, this study explores a combination system, made up of an ERP and informality, intended to provide organisations with efficient and flexible performance simultaneously. In addition, this research analyses the benefits and challenges of using the system. The research was based on socio-technical system (STS) theory which contains two dimensions: 1) a technical dimension which evaluates the performance of the system; and 2) a social dimension which examines the impact of the system on an organisation. A mixed method approach has been followed in this research. The qualitative part aims to understand the constraints of using a single ERP system, and to define a new system corresponding to these problems. To achieve this goal, four Chinese companies operating in different industries were studied, all of which faced challenges in using an ERP system due to complexity and uncertainty in their business environments. The quantitative part contains a discrete-event simulation study that is intended to examine the impact of operational performance when a company implements the hybrid system in a real-life situation. Moreover, this research conducts a further qualitative case study, the better to understand the influence of the system in an organisation. The empirical aspect of the study reveals that an ERP with pre-determined business activities cannot react promptly to unanticipated changes in a business. Incorporating informality into an ERP can react to different situations by using different procedures that are based on the practical knowledge of frontline employees. Furthermore, the simulation study shows that the combination system can achieve a balance between efficiency and flexibility. Unlike existing research, which emphasises a continuous improvement in the IT functions of an enterprise system, this research contributes to providing a definition of a new system in theory, which has mixed performance and contains both the formal practices embedded in an ERP and informal activities based on human knowledge. It supports both cost-efficiency in executing business transactions and flexibility in coping with business uncertainty.This research also indicates risks of using the system, such as using an ERP with limited functions; a high cost for performing informally; and a low system acceptance, owing to a shift in organisational culture. With respect to practical contribution, this research suggests that companies can choose the most suitable enterprise system approach in accordance with their operational strategies. The combination system can be implemented in a company that needs to operate a medium amount of volume and variety. By contrast, the traditional ERP system is better suited in a company that operates a high-level volume market, while an informal system is more suitable for a firm with a requirement for a high level of variety.

Design verification and validation in product lifecycle

The verification and validation of engineering designs are of primary importance as they directly influence production performance and ultimately define product functionality and customer perception. Research in aspects of verification and validation is widely spread ranging from tools employed during the digital design phase, to methods deployed for prototype verification and validation. This paper reviews the standard definitions of verification and validation in the context of engineering design and progresses to provide a coherent analysis and classification of these activities from preliminary design, to design in the digital domain and the physical verification and validation of products and processes. The scope of the paper includes aspects of system design and demonstrates how complex products are validated in the context of their lifecycle. Industrial requirements are highlighted and research trends and priorities identified. © 2010 CIRP.

Immunological protein-protein interactions:a critical reflection

Life, and the biochemistry of which it is ultimately comprised, is built from the interactions of proteins, and the study of protein-protein interactions is fast becoming a central feature of molecular bioscience. This is as true of immunobiology as it is of other areas of the wider biological milieu. Protein-protein interactions within an immunological setting comprise both the kind familiar from other areas of biology and instantiations of protein-protein interactions special to the immune arena. Of the generic kind of protein-protein interaction, co-stimulatory receptors, such as CD28, and the interaction of accessory proteins, such as CD4 or CD8, are amongst the most prevalent and apposite of examples. The key examples of special immunological instantiations of protein-protein interactions are the binding of antigens by antibodies and the formation of peptide-MHC-TCR complexes; both prime examples of vital molecular recognition events mediated by protein-protein interactions. In this brief review, and within the context of this burgeoning field, we examine immunological protein-protein interactions, focussing on the problematic nature of defining such interactions. © 2011 by Nova Science Publishers, Inc.

On the role of surface roughness in the aerodynamic performance and energy conversion of horizontal wind turbine blades:a review

Summary: Renewable energy is one of the main pillars of sustainable development, especially in developing economies. Increasing energy demand and the limitation of fossil fuel reserves make the use of renewable energy essential for sustainable development. Wind energy is considered to be one of the most important resources of renewable energy. In North African countries, such as Egypt, wind energy has an enormous potential; however, it faces quite a number of technical challenges related to the performance of wind turbines in the Saharan environment. Seasonal sand storms affect the performance of wind turbines in many ways, one of which is increasing the wind turbine aerodynamic resistance through the increase of blade surface roughness. The power loss because of blade surface deterioration is significant in wind turbines. The surface roughness of wind turbine blades deteriorates because of several environmental conditions such as ice or sand. This paper is the first review on the topic of surface roughness effects on the performance of horizontal-axis wind turbines. The review covers the numerical simulation and experimental studies as well as discussing the present research trends to develop a roadmap for better understanding and improvement of wind turbine performance in deleterious environments.

Board gender diversity in UK firms – recent trends and performance eEffects

This paper provides an overview of the position of women directors in UK firms. Based on data for all UK firms with more than three directors, this data provides a comprehensive picture of the position of women in UK business leadership and contributes to our understanding of progress towards achieving greater gender balance in the boardroom. Five key points emerge. •Female directors account for around 1:4 directors in UK firms but only around 1:10 businesses in the UK are female controlled. •Only 1:226 larger firms in this category have a majority of female directors. •The overall proportion of female directors in the UK has grown in recent years but slowly. At the rate of progress achieved over the 2003-2005 period, it will be the year 2225 before gender balance in company directorships is achieved in the UK. •There are a significant and interesting group of 12, 600 sisterhood companies in the UK – those wholly owned and led by women. Although they are predominantly services, these do firms exist in all business sectors with a focus on smaller companies. These firms represent an interesting potential focus for future research. •Our analysis of board gender diversity and business growth suggests that there is a business cost to gender balance in terms of foregone growth.

The past, present and future of observational research in marketing

Purpose - To introduce the contents of the special issue, and provide an integrative overview of the development of observational methodologies in marketing research, as well as some directions for the future. Design/methodology/approach - A historical review of the development of observational methods, beginning with philosophical foundations, is provided. Key philosophical debates are summarized, and trends in observational methods are described and analyzed, with particular reference to the impact of technology. Following this, the contributions to the special issue are summarized and brought together. Findings - Observational research in marketing is more than the well-known method of "participant-observation." In fact, technology has the potential to revolutionize observational research, and move it beyond a solely "qualitative" method. The internet, video, scanner-tracking, and neuroimaging methods are all likely to have a big impact on the development of traditional and innovative observation methods in the future. The articles in the special issue provide a good overview of these developments. Research limitations/implications - The views of the authors may differ from those of others. Practical implications - Observation is a far more wide-ranging strategy than many perceive. There is a need for more expertise in all types of observational methodologies within marketing research schools and departments, in order to take account of the vast opportunities which are currently emerging. Originality/value - Provides an original perspective on observational methods, and serves as a useful overview of trends and developments in the field.

Can grassroots organisations and NGOs substitute for the State in Russia? A review of the literature and suggestions for a future research agenda

The paper investigates the relationship between civil society and the state. Using the unique lens of the state-substitution (the process whereby civil society organisations take on government roles) the paper reviews the literature and highlights three key issues: - Civil society is weak in Russia and its contribution to democracy development is limited - The Russian State has be withdrawing from its responsibilities to care for its citizens, leaving a field of opportunity for civil society organisations. - The state has subsequently began to encroach on civil society organisations mainly through the use of legislative changes and government sponsored organisations These trends have far reaching implications for civil society organisations, in particular those which take up or take over government roles and responsibilities. The literary evidence shows that the Russian state leverages its political power into the sphere of civil society similar to how it regained control over the economy in the early 2000s. This Russian variant of civil society attributes the state as a key player in all societal spheres.

Clinical pharmacy:post-registration learning trends of community pharmacists

While CPD is now a mandatory requirement for Australian pharmacists, there has been little research to identify preferred learning resources, or barriers and motivators for continuing education and CPD participation. This study aimed to identify post-registration learning trends of community pharmacists in western Australia, as well as their opinions on post-registration learning.

Post-registration learning trends of community pharmacists

Background: Some Australian pharmacists use continuing education to maintain knowledge and acquire new information. There has been a progression from continuing education to continuing professional development (CPD) - a mandatory requirement for pharmacists in all jurisdictions of Australia. Aim: To identify post-registration learning trends of community pharmacists in Western Australia. Method: A questionnaire was developed and administered by face-to-face interviews with community pharmacists in metropolitan Perth. Pharmacists registered for less than 12 months and pharmacists working in hospitals were excluded. Results: 103 pharmacists were approached with a response rate of 95%. Journals (41%), reference books (23%) and the Internet (18%) were the most commonly used educational resources cited by pharmacists. Keeping scientific information up-to-date (39%) and gathering practical knowledge (22%) were the leading motivators for pharmacists to participate in continuing education. Factors that hindered participation in continuing education included lack of time (34%), family commitments (21%) and business commitments (21%). 79% of pharmacists agreed with the concept of mandatory CPD. 47% of pharmacists suggested that the primary sanction for not complying with mandatory CPD should be counselling to determine reasons for non-compliance. Conclusion: Community pharmacists preferred educational resources that were easily accessible at convenient times. Most pharmacists were able to fulfil the requirements of CPD, however, further educational support and promotion would ensure the successful uptake of CPD by community pharmacists in Western Australia.

Whither research in marketing?

Purpose - To introduce the contents of this special issue on research in marketing and comment on the development of the discipline in UK universities. Design/methodology/approach - Relates each paper to a taxonomy of academic research and comments on their content. Examines major trends in higher education and relates them to the fortunes of marketing educators. Findings - There are reasons to be cheerful about academic marketing in the UK: there are clearly opportunities to publish in the world's leading academic journals, increased funding for the discipline, the acceptability of a wide range of methodologies and the increasing influence of marketing. Less encouraging is the naïve and destructive competition between universities and the consequent destruction of academic development. Research limitations/implications - This is a UK perspective that depends on limited knowledge of other than a few other countries. Practical implications - There are good reasons to be positive about an academic career in marketing, but also a desperate need to tackle the naïve strategies of universities and to intervene to mend the gaps in the development of academic marketers. Originality/value - Gives an insight in to the range of research in marketing, and an insight into the opportunities and pitfalls of a career in academic marketing research. © Emerald Group Publishing Limited.

Tracking and updating academic research in selling and sales management:a decade later

This study examines the state of academic research in selling and sales management (S&SM) from the years 2003-7, ten years after the data collected by Moncrief, Marshall, and Watkins (2000). Sales articles are reviewed that appeared in 19 marketing journals and evidence is provided on the state of the S&SM discipline by comparing the number of authors, authorships, and publications versus a comparable five-year period a decade ago. Of interest are the universities that produce and employ faculty in S&SM and to identify those schools and geographic regions that are publishing the majority of articles. Publication distribution trends across journals are also examined. A dramatic increase in non-U.S. authors and authorships is noted versus the prior study. Overall, the findings indicate that, perhaps contrary to some popular misconceptions, the state of S&SM research is healthy, vibrant, and evolving.
