The role and theoretical evolution of knowledge translation and exchange in public health

Background There is an increased emphasis in public health research on effective models and strategies to support knowledge translation (KT), the exchange, synthesis and ethically sound application of research findings within a complex set of interactions among researchers and knowledge users. In other words, KT can be seen as an acceleration of the knowledge cycle—an acceleration of the natural transformation of knowledge into use (Canadian Institutes of Health Services Research. Knowledge Translation Strategy, 2004). The most recent conceptualizations consider the complexities of public health decision-making. The role of practitioners and communities is increasingly considered.

Methods We identify, describe and discuss the theoretical underpinnings of KT and recommend a way forward to build the evidence for more effective practice.

Results Theoretical perspectives increasingly influence research on KT in public health. A range of innovative work is being conducted to explore methods for KT using practical tools, often with the support of government.

Conclusions KT describes a crucial and to date under-developed element of the research process. There is an important gap in theoretically informed empirical studies of effectiveness of proposed approaches in public health, health promotion and preventive medicine, and thus much of the debate remains abstract. There is clearly an urgent policy need to establish the effectiveness of KT models in a range of contexts. This must include both the consideration of development and the utilization of knowledge.

Evolution of egg size and fertilisation efficiency in sea stars: large eggs are not fertilised more readily than small eggs in Patiriella (Echinodermata: Asteroidea)

Fertilisation kinetics theory suggests that, when sperm are limiting, the larger eggs of broadcast-spawning marine organisms ought to be fertilised more frequently than smaller eggs, because they provide a bigger target for searching sperm. Whilst this effect has been demonstrated within species, it is not known if this pattern holds among species. We tested whether a large difference in egg size between congeneric seastars with contrasting planktotrophic and lecithotrophic modes of development results in differences in the likelihood of eggs being fertilised in sperm-limiting situations. Measurement of egg sizes and sperm swimming speeds led to the prediction that the sperm–egg collision rate constant for Patiriella calcar (420-µm-diameter egg) should be nine times greater than for P. regularis (140-µm-diameter egg). Although the eggs of P. calcar should be fertilised at greater rates in low sperm concentrations, they were not. When gametes were allowed to mix for 10 s, the hypothesis that P. calcar eggs required less sperm than P. regularis to ensure 50% of eggs were fertilised was rejected. When gametes were mixed for 5 min, P. regularis eggs were more frequently fertilised, but the difference was not statistically significant. We conclude there must be a difference between these species in the likelihood that when a sperm finds a conspecific egg it can successfully fertilise. This apparent uncoupling of egg size and likelihood of fertilisation suggests that fertilisation is not a major constraint on the evolution of egg size in these seastars.

Career orientations of marketing employees : an empirical analysis

There is a distinct gap in research in marketing in relation to understanding the role of marketing employees in organisational marketing performance, in contrast to the usual focus on identifying the contribution of successfully completing marketing tasks in the pursuit of organisational marketing objectives. The major exception to this has been research related to sales personnel, as a subset of all marketing personnel, but even this has usually been from a sales management perspective and not principally from the viewpoint of individual employees. The current study explored the career orientations of marketing employees in relation to the demographic profile and other work-related characteristics of marketing employees. Operationalised by Schein's (1990) Career Orientations Inventory, the 'internal career' of 78 marketing employees at the Australian headquarters of a major multinational manufacturing firm was examined. Sample means indicated that 'Lifestyle', 'Technical Functionality', and 'Pure Challenge' were the dominant career orientations, but a 'General Managerial' orientation also emerged as important, when individual 'Career Anchors' were examined. An 'Entrepreneurial' anchor was found to be the least dominant of the eight anchors measured, which may be seen as somewhat surprising for Marketing employees. Significant relationships were found between some demographic variables and the dominant career orientations, but overall, career orientation tended to be unrelated to the demographic variables. Future research will examine the relationships between employee career orientation and individual position, and marketing productivity.

Issues in measuring the return of marketing investment in sporting club brands

This paper examines approaches to the measurement of brand value, and discusses their applicability to the various parties and branded products relevant to professional football clubs. It is concluded that the applicability of many of these measures of performance to sporting club brands is questionable. In order to provide an appropriate measure of the return on investment in brand loyalty to both the sporting club brand and sponsor-related products, the use of nonfinancial performance measures is critical. This paper suggests future research directions to enable greater consistency of the measurement of the return on marketing investment for sporting club brands.

A conceptual model of the role of marketing employees in marketing performance

In general, there is a gap in research in marketing in relation to understanding the role of marketing employees in organisational marketing performance. An exception to this is the performance of salespeople as a subset of all marketing employees. Broader human resource management research into the people-performance link is also severely limited The proposed model argues that marketing employees are one of an organisation's strategic assets and are essential to the superior performance of the firm. Based on the People and Performance model (Purcell et al. 2003), the current model conceptualises marketing employee competencies as a precursor to performance outcomes and is, specifically, concerned with identifying and understanding the nature of the marketing employee performance relationship. Of note, where current performance research, in the main, adopts intermediate measures of labour turnover and labour productivity, this model proposes a three-tiered approach to performance measurement.

Designing educational tasks for success in industry: a reflection on the evolution of business communication studies in tertiary education

This paper is the result of a "Rip Van Winkle" experience I had concerning the teaching of Business Communication. The paper focuses on the remarkable expansion in the curriculum of the traditional "Business Communication" or "Business Writing" course offered by many tertiary institutions around the world. Based on 25 years of personal observation and experience in a number of educational settings, the paper will trace the increasing sophistication and complexity of the study of business communication from one that covered little more than lessons in the design of hardcopy memos, letters, and reports to one that now covers a broad spectrum of topics such as "emotional intelligence," "intercultural communication," "effective public speaking," as well as the effects of purpose and audience on the design of a wide variety of business communications.

An example of an effective task that involves a number of on the job activities is provided in the form of a ready to use assignment that is applicable in a number of contexts.

The influence of marketing logistics networks on organisational performance in Australia and New Zealand

Predictions concerning the influence of traditional and online marketing logistics network competency on organisational performance were tested via structural equation modelling employing a sample of Australian and New Zealand companies. The study finds a significant influence of the use of traditional marketing logistics networks on organisational performance, but that the use of the Web in this regard is yet to have such an influence.

Evolution of Pinnipedia lactation strategies: a potential role for α-lactalbumin?

Despite the considerable variation in milk composition found among mammals, a constituent common across all groups is lactose, the main sugar and osmole in most eutherians milk. Exceptions to this are the families Otariidae (fur seals and sea lions) and Odobenidae (walruses), where lactose has not been detected. We investigated the molecular basis for this by cloning α-lactalbumin, the modifier protein of the lactose synthase complex. A mutation was observed which, in addition to preventing lactose production, may enable otariids to maintain lactation despite the extremely long inter-suckling intervals during the mother's time at sea foraging (more than 23 days in some species).

Microstructure evolution of TI-SN-NB alloy prepared by mechanical alloying

In the present study, Ti-16Sn-4Nb alloy was prepared by mechanical alloying (MA). Optical microscopy, scanning electron microscopy combined with energy dispersive X-ray analysis (SEM-EDX), and X-ray diffraction analysis (XRD) were used to characterise the phase transformation and the microstructure evolution. Results indicated that ball milling to 8 h led to the formation of a supersaturated hcp α-Ti and partial amorphous phase due to the solid solution of Sn and Nb into Ti lattice. The microstructure of the bulk sintered Ti-16Sn-4Nb alloy samples made from the powders at shorter ball milling times, i.e. 20 min- 2 h, exhibited a primary α surrounded by a Widmanstätten structure (transformed β); while in the samples made from the powders at longer ball milling times, i.e. 5- 10 h, the alloy evolved to a microstructure with a disordered and fine β phase dispersed homogeneously within the α matrix. These results contribute to the understanding of the microstructure evolution in alloys of this type prepared by powder metallurgy.

The evolution of an online community - a case study

This article reflects findings from a long term case study of an online community of practice established through a network for the professional education of teachers in Ontario, Canada. The Education Network of Ontario/Réseau éducatif de l'Ontario (ENO/REO) was created in 1992–1993 to support and connect teachers from kindergarten to grade 12 in the province of Ontario. Its mandate was to ensure that all teachers had free access to the Internet and to each other and to encourage the development of skills in the area of information and communication technology with the ultimate goal of using those skills to improve classroom practice. The study investigated whether information technology had the potential to connect teachers to each other in order to build the capacity to create networks where professional learning could take place in a cost-efficient and flexible time and/or place. It was found that participants were early adopters who enjoyed innovation, that online networkswere supportive for learning but hard to maintain over time, and though they supported the integration of technology in the classroom, other barriers within schools could challenge this effect.

Evolution of class I cytokine receptors

Background
The Class I cytokine receptors have a wide range of actions, including a major role in the development and function of immune and blood cells. However, the evolution of the genes encoding them remains poorly understood. To address this we have used bioinformatics to analyze the Class I receptor repertoire in sea squirt (Ciona intestinalis) and zebrafish (Danio rerio).
Results
Only two Class I receptors were identified in sea squirt, one with homology to the archetypal GP130 receptor, and the other with high conservation with the divergent orphan receptor CLF-3. In contrast, 36 Class I cytokine receptors were present in zebrafish, including representative members for each of the five structural groups found in mammals. This allowed the identification of 27 core receptors belonging to the last common ancestor of teleosts and mammals.
Conclusion
This study suggests that the majority of diversification of this receptor family occurred after the divergence of urochordates and vertebrates approximately 794 million years ago (MYA), but before the divergence of ray-finned from lobe-finned fishes around 476 MYA. Since then, only relatively limited lineage-specific diversification within the different Class I receptor structural groups has occurred.

The role of marketing employees in marketing performance : an empirical investigation

The role of marketing employees in contributing to marketing performance (individual and organisational), has, in general, been under-researched. Most research in marketing has focused on the activities of marketing employees and the outputs of those activities, rather than the inputs, i.e., the abilities, skills, or knowledge of the marketing employees themselves. This study represents a unique insight into the marketing capabilities and marketing performance of employees within a multinational organisation, as reported by the employees themselves. Using Structural Equation Modelling (SEM), strong support was found for a systems model of marketing competency marketing performance, suggesting that such relationships are complex and are not studied readily in isolation from external factors. Organisations that are able to conceptualise, operationalise, measure, monitor, and address marketing employee competency, intentions, and perceptions, as well as maintain the appropriate levels of management control, should have a greater likelihood of creating high performing employees, than those organisations that are unable to focus on these core aspects of people's performance. In addition, those same employees are likely to be more satisfied, motivated, and committed, require less assistance and time to complete tasks, and have greater productivity and be less likely to leave the orga.'1isation.
