Phelan (2000) has produced a complex bibliometric analysis of the international contribution of Australian educational research based upon publications and citations reported in the journals indexed by the Institute for Scientific Information - the Standards & Poors of the academic world. This paper examins Phelan's analysis, showing its strengths and weaknesses, as well as examining his proposal for the establishment of an Australian database along the lines of the ISI's index.

Background
Sporting organisations provide an important setting for health promotion strategies that involve policies, communication of healthy messages and creation of health promoting environments. The introduction of policy interventions within sporting organisations is one strategy to target high risk behaviours such as smoking, alcohol consumption, excess sun exposure, unhealthy eating and discrimination.

Objectives
To review all controlled evaluation studies of policy interventions organised through sporting settings to increase healthy behaviour (related to smoking, alcohol, healthy eating, sun protection, discrimination, safety and access).

Search strategy
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PsyclNFO, CINAHL, SPORTDiscus, Sociological Abstracts, Dissertation Abstracts, freely available online health promotion and sports-related databases hosted by leading agencies, and the internet using sport and policy-related key words. We identified further studies in the bibliographies of articles and by contacting authors of key articles in the area.

Selection criteria
We aimed to identify research that had used study designs that incorporated an evaluated intervention and comparison. Uncontrolled studies, meeting other inclusion criteria, were to be reported in an annex to the review.
Types of studies: Studies in which sporting organisations were allocated to a policy intervention or control/comparison group. No minimum follow-up required.
Types of participants: People of all ages.
Types of interventions: Any policy intervention implemented through sporting organisations to instigate and/or sustain healthy behaviour change, intention to change behaviour, or changes in attitudes, knowledge or awareness of healthy behaviour. Policies must address any of the following: smoking, alcohol, healthy eating, sun protection, access for disadvantaged groups, physical safety (not including injuries), and social and emotional health (e.g.. anti-vilification, anti-discrimination).
Types of outcome measures: Behaviour change, intention to change behaviour, change in attitudes, knowledge or awareness of healthy behaviour, and policy presence.

Data collection and analysis
We assessed whether identified citations were controlled evaluation studies and investigated the use of policy implemented in sporting settings. Abstracts were independently inspected by two reviewers and full papers were obtained where necessary. As no controlled evaluation studies were located, no data collection or analysis was undertaken. No uncontrolled studies meeting other inclusion criteria were identified and therefore no annex is presented.

Main results
No rigorous studies were located to test the effectiveness of policy interventions organised through sporting organisations to increase healthy behaviours, attitudes, knowledge or inclusion of health oriented policies within the organisarions.

Authors' conclusions
We were unable to find any controlled studies to guide the use of policy interventions used in sporting settings. The search process revealed a number of case studies with anecdotal reporting of outcomes. We strongly recommend that rigorous evaluation techniques are employed more commonly in this field to illuminate the impact of health promoting policy on outcomes, and the contexts and processes which are likely ro be effective in reducing harmful behaviours.

Control of a group of mobile robots in a formation requires not only environmental sensing but also communication among vehicles. Enlarging the size of the platoon of vehicles causes difficulties due to communications bandwidth limitations. Decentralized control may be an appropriate approach in those cases when the states of all vehicles cannot be obtained in a centralized manner. This paper presents a solution to the problem of decentralized implementation of a global state-feedback controller for N mobile robots in a formation. The proposed solution is based on the design of functional observers to estimate asymptotically the global state-feedback control signals by using the corresponding local output information and some exogenous global functions. The proposed technique is tested through simulation and experiments for the control of groups of Pinoneer-based non-holonomic mobile robots.

This paper examines the degree to which works appearing in JM, JMR and JCR cite materials other than academic journals. The results suggest the number of citations to proceedings has fallen since earlier works (Anderson and Haley, 1984). This may be explained by the increased number of marketing related journals available in hard copy and through electronic databases. Citations of non-journal materials within marketing literature are however, higher than were found by Armstrong and Pagell (2003) in the forecasting literature. Some suggestions for future research are provided.

This paper examines the degree to which articles appearing in JM, JMR, and JCR cite different types of references (journals, books, book chapters, conference proceedings, professional and popular press, and “others”) between 1975 and 2003. The results suggest that the number of citations to journals articles has increased over time and there have been significant falls in reference to non-journal sources of materials. References to some non-journal sources (i.e., newspaper and professional materials) have increased in JCR and JMR, but decreased in JM. The impact of shifts in the types of citation materials on knowledge development is also discussed.

This paper examines all citations and self-citations to a list of 95 finance journals appearing in the Journal of Finance, Journal of Financial Economics and Review of Financial Studies from 1995 through 2005. Additionally, the publication profile of 100 prolific authors in top-tier finance journals is tabulated for these 95 journals. Citations to non-finance journals in economics and accounting are also tabulated for comparison with their finance counterpart along with working papers. Six ranking schemes are constructed with each scheme identifying the top fifty finance journals. Citations to finance journals are highly concentrated within ten journals and similarly for self-citations. Authors of papers appearing in top-tier finance journals pay scant attention to the bulk of research published in other finance journals. Furthermore, these authors cite other economic journals with greater frequency than their counterpart in finance. Of the top fifty finance journals identified in this paper, only 21 are listed in Social Sciences Citation Index (SSCI), and this compares to approximately 500 listed economic journals. Some glaring omissions from SSCI are identified, but most notably the Journal of Applied Corporate Finance, Journal of Financial Research, Journal of Empirical Finance and Journal of Fixed Income. An analysis of 2006 citations patterns is also presented. The top-tier mantra assigned to finance journals has a void with the decision by the Journal of Business to cease publication with the November 2006 issue. This paper identifies five finance journals anyone of which could potentially fill the void.

Background : In the past forty years, many gains have been made in our understanding of the concept of research utilization. While numerous studies exist on professional nurses' use of research in practice, no attempt has been made to systematically evaluate and synthesize this body of literature with respect to the extent to which nurses use research in their clinical practice. The objective of this study was to systematically identify and analyze the available evidence related to the extent to which nurses use research findings in practice.

Methods : This study was a systematic review of published and grey literature. The search strategy included 13 online bibliographic databases: Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, EMBASE, HAPI, Web of Science, SCOPUS, OCLC Papers First, OCLC WorldCat, ABI Inform, Sociological Abstracts, and Dissertation Abstracts. The inclusion criteria consisted of primary research reports that assess professional nurses' use of research in practice, written in the English or Scandinavian languages. Extent of research use was determined by assigning research use scores reported in each article to one of four quartiles: low, moderate-low, moderate-high, or high.

Results : Following removal of duplicate citations, a total of 12,418 titles were identified through database searches, of which 133 articles were retrieved. Of the articles retrieved, 55 satisfied the inclusion criteria. The 55 final reports included cross-sectional/survey (n = 51) and quasi-experimental (n = 4) designs. A sensitivity analysis, comparing findings from all reports with those rated moderate (moderate-weak and moderate-strong) and strong quality, did not show significant differences. In a majority of the articles identified (n = 38, 69%), nurses reported moderate-high research use.

Conclusions : According to this review, nurses' reported use of research is moderate-high and has remained relatively consistent over time until the early 2000's. This finding, however, may paint an overly optimistic picture of the extent to which nurses use research in their practice given the methodological problems inherent in the majority of studies. There is a clear need for the development of standard measures of research use and robust well-designed studies examining nurses' use of research and its impact on patient outcomes. The relatively unchanged self-reports of moderate-high research use by nurses is troubling given that over 40 years have elapsed since the first studies in this review were conducted and the increasing emphasis in the past 15 years on evidence-based practice. More troubling is the absence of studies in which attempts are made to assess the effects of varying levels of research use on patient outcomes.

Purpose – This paper aims to present a quantitative analysis of arts management/marketing articles in leading general management/marketing journals, including an examination of the extent to which those top tier journal articles on arts/culture-related topics cite authors of leading arts management journal articles.

Design/methodology/approach – Using bibliometric techniques, this study examines the content of 20 top tier management and marketing journals over 22 years to identify articles published on arts management/marketing, which authors were cited, and from which arts management/marketing journals.

Findings – Analysis indicates that: relatively few citations in the top management/marketing journals reference arts management/marketing journals; assessment of interaction between the parent management/marketing disciplines and the arts management/marketing sub-discipline indicates that authors draw upon a large reserve of diverse literatures; and top journal arts-related management/marketing articles tend to utilize citations to journal articles grounded in the social sciences and aesthetics of management, with an increasing trend of citations to arts management/marketing journals.

Research limitations/implications – This study of the extent to which top journals have published arts/culture-related articles and the citation impact of arts management/marketing journals is the initial academic study on the topic and suggests opportunities for further research.

Practical implications – Analysis of arts management/marketing journal impact contributes to professionalization of the field and increased perceived value of those journals by industry practitioners.

Originality/value – This research is the first to examine the spectrum of arts management/marketing literature, including both top general management/marketing journals and sector-oriented arts management/marketing journals, establishing a body of knowledge for augmentation by future research over time.

This paper reviews the work published in JMTP during its first 20 years. It finds extensive global coverage in terms of authors and material, despite a U.S. emphasis. In addition, a diversity of topics is covered and is making a significant contribution, as defined by citations, to broader academic discourse. The works published have a strong applied focus, although this might be expected to have been higher given the journal's applied foundations. The paper also identifies the most prolific individuals and institutions, based on the number of articles published and citations to those articles. The paper concludes that JMTP has made a valuable contribution to marketing academia and its global recognition continues to grow.

Why do people become teachers? Some of the reasons for entering science and mathematics teaching include: wanting to make a difference, good job conditions, liking young people, loving science and maths, being good at teaching, having had a good maths/science teacher, a shortage of teachers, and a love of learning.

We need good teachers, and especially teachers with good science and chemistry backgrounds. It is also true of all school levels, including primary. Job satisfaction and the joy of teaching are not enough. Everyone needs encouragement, acknowledgement and respect. Everyone needs to know that they and their work are valued. Teachers need these too. It is a good investment in the nation’s future.
