Teacher subject specialisms and their relationships to learning styles, psychological types and multiple intelligences: implications for course development

This study explores issues in teacher education that increase our understanding of, and response to, the individual differences displayed by learners. A large undergraduate teacher education cohort provided evidence of the range and distribution of preferences in learning styles, psychological types and multiple intelligences. This information revealed that distributions of scores on the Kolb Learning Style Inventory, the Myers-Briggs Type Indicator, and the Multiple Intelligences Checklist for Adults provide evidence about the scope and range of differences between four teacher subject specialisms. This rich information about those participating in teacher education courses provides some guidance for educating those with their own clear preferences to the range of different preferences expressed by many other learners and highlights the existence of four sets of major differences in approaches to teaching and learning in prospective teachers.

How important are different types of temperate woodlands for ground-foraging birds?

There is widespread concern about population decline in a number of woodland-dependent birds in southern Australia. Of all declining species, approximately half forage on the ground. This study examined the avifaunal assemblages of temperate woodlands of the Northern Plains, Victoria, to investigate the importance of woodland habitats for ground-foraging species. Four main types of woodland were surveyed (white cypress-pine, black box, grey box and river red gum) and, in total, 89 bird species were detected. All four woodland types differed in habitat structure and, in turn, supported significantly different avifaunal assemblages. Forty of the 89 species (45%) foraged, at least in part, on the ground. Species richness and abundance of ground-foragers differed significantly between woodland types, being highest in white cypress-pine and black box. There was a greater richness of ground-foragers during the breeding than non-breeding season, but abundance did not vary seasonally. Overall, ground-foraging birds comprised a greater proportion of species (>55%) and individuals (>60%) in white cypress-pine and black box woodland than in grey box and river red gum (42–48% of species, <50% individuals). Those ground-foragers regarded as declining also occurred in greatest richness in white cypress-pine woodlands, one of the most depleted habitats in the region. The lowest richness of ‘declining’ ground-foraging species was in river red gum woodland, the most widespread woodland type. Throughout Australia, the proportion of ground-foraging species in bird assemblages tends to be greater in temperate, semi-arid or arid woodlands than in moist forests and rainforests. However, in many regions woodland habitats are severely depleted and their open ground layer is particularly vulnerable to degradation. The extent of suitable habitat for ground-foraging birds in temperate woodlands may be much less than is apparent from current measures of tree cover. Sustainable management of drier (non-riverine) temperate woodlands is required to conserve this important element of the Australian avifauna.

Behavioral characteristics of men accused of rape: evidence for different types of rapists

The aim of this study was to determine whether the behavioral characteristics demonstrated by rapists clustered together into groups that were similar to the common rapist typology in the literature: anger, power exploitative, power reassurance, and sadistic. Two studies were conducted to examine the evidence for this typology. Study 1 involved the analysis of data from 130 men charged with sexual assault and Study 2 involved the analysis of court transcripts from 50 rape cases tried through the court system. The results of Study 1 revealed that there was some validity to the characteristics usually associated with each of the four types of rape, especially for the power reassurance and sadistic rapists. However, there were some unexpected outliers within both the anger and power exploitative types of rapists, which may suggest that there is more than one type of anger rapist and more than two types of power rapists. The results of Study 2 very closely replicated the results of Study 1. Future research needs to focus on the behavioral, motivational, and cognitive characteristics associated with each of the types of rapists and research them separately, so that it is possible to further evaluate the evidence for the typology identified in this study.

Giving content to the principle of proportionality: happiness and pain as the universal currency for matching offence seriousness and penalty severity

The principle of proportionality prescribes that the punishment should equal the crime. It is one of the most important principles of sentencing. Yet, despite its widespread acceptance it offers no meaningful guide to sentencing. Hence penalty levels fluctuate greatly between jurisdictions and within jurisdictions. This is because there is no universally agreed criterion for measuring offence seriousness or penalty severity. This article suggests that the appropriate criteria for matching offence seriousness and penalty severity is the level of unhappiness or pain stemming from each of these impositions. Thus, for example, the level of pain meted out to a rape offender should equal the level of pain caused to a rape victim. Emerging scientific studies on human well-being and happiness show that human beings are similarly built in terms of the experiences that are either conducive or inimical to well-being. This commonality provides a strong foundation to be confident to make reasonably accurate predictions concerning the extent to which adverse events, such as being the victim of a criminal offence or subjected to a form of criminal sanction will stifle human flourishing. This will then allow us to match accurately offence seriousness and penalty level.

Recruitment of the infaunal bivalve Soletellina Alba (Lamark,1818) (Bivalvia: Psammobiidae) in response to different sediment types and water depths within the intermittently open Hopkins River estuary

Studies examining recruitment processes for soft-sediment macroinvertebrate fauna in intermittent estuaries are rare and most studies of active habitat selection have been tested in the laboratory rather than the field. The present field study examined whether recruitment of the infaunal bivalve Soletellina alba was influenced by water depth and sediment particle size in the intermittent Hopkins River estuary, southern Australia. The number of recruits in sediment trays differed between water depths, but active habitat selection was not evident across treatments of varying sediment particle size. The use of sediments with varying particle sizes also provided an opportunity to identify potential discontinuities in body-size distributions of recruits associated with varying habitat architecture. The length (mm) of recruits was converted to the same scale used to express sediment particle size (i.e. phi units: phi = − log2 of sediment particle size). The size of recruits differed across water depths, but did not differ across treatments with fine (phi = 3) versus coarse (phi = 1) sediment, and no relationships were apparent between bivalve size and sediments consisting of varying particle size. These patterns of recruitment do not correspond with the distribution of adult S. alba within the Hopkins River estuary. Previous sampling has shown that abundances of juvenile and adult S. alba are variable across time, site and water depth, but are often greater at the deeper water depth (1.05 m below the Australian Height Datum). However, recruitment during the present study was greatest at the shallower water depth (0.05 m below AHD), and the apparent absence of active habitat selection suggests that the distribution of adults is unlikely to be attributable to differences in recruitment associated with sediments of varying particle size.

UCP3 protein regulation in human skeletal muscle fibre types I, IIa andIIx is dependent on exercise intensity.

It has been proposed that mitochondrial uncoupling protein 3 (UCP3) behaves as an uncoupler of oxidative phosphorylation. In a cross-sectional study, UCP3 protein levels were found to be lower in all fibre types of endurance-trained cyclists as compared to healthy controls. This decrease was greatest in the type I oxidative fibres, and it was hypothesised that this may be due to the preferential recruitment of these fibres during endurance training. To test this hypothesis, we compared the effects of 6 weeks of endurance (ETr) and sprint (STr) running training on UCP3 mRNA expression and fibre-type protein content using real-time PCR and immunofluorescence techniques, respectively. UCP3 mRNA and protein levels were downregulated similarly in ETr and STr (UCP3 mRNA: by 65 and 50 %, respectively; protein: by 30 and 27 %, respectively). ETr significantly reduced UCP3 protein content in type I, IIa and IIx muscle fibres by 54, 29 and 16 %, respectively. STr significantly reduced UCP3 protein content in type I, IIa and IIx muscle fibres by 24, 31 and 26 %, respectively. The fibre-type reductions in UCP3 due to ETr, but not STr, were significantly different from each other, with the effect being greater in type I than in type IIa, and in type IIa than in type IIx fibres. As a result, compared to STr, ETr reduced UCP3 expression significantly more in fibre type I and significantly less in fibre types IIx. This suggests that the more a fibre is recruited, the more it adapts to training by a decrease in its UCP3 expression. In addition, the more a fibre type depends on fatty acid beta oxidation and oxidative phosphorylation, the more it responds to ETr by a decrease in its UCP3 content.

Multiple types of dieting prospectively predict weight gain during the freshman year of college.

The freshman year of college is a period of heightened risk for weight gain. This study examined measures of restrained eating, disinhibition, and emotional eating as predictors of weight gain during the freshman year. Using Lowe's multi-factorial model of dieting, it also examined three different types of dieting as predictors of weight gain. Sixty-nine females were assessed at three points during the school year. Weight gain during the freshman year averaged 2.1 kg. None of the traditional self-report measures of restraint, disinhibition, or emotional eating were predictive of weight gain. However, both a history of weight loss dieting and weight suppression (discrepancy between highest weight ever and current weight) predicted greater weight gain, and these effects appeared to be largely independent of one another. Individuals who said they were currently dieting to lose weight gained twice as much (5.0 kg) as former dieters (2.5 kg) and three times as much as never dieters (1.6 kg), but the import of this finding was unclear because there was only a small number of current dieters (N=7). Overall the results indicate that specific subtypes of dieting predicts weight gain during the freshman year better than more global measures of restraint or overeating.

The impact of Porter's strategy types on the role of market research and customer relationship management

Purpose – This paper seeks to investigate the influence of Porter’s strategy types on the use of customer relationship management (CRM) techniques and traditional market research, against theoretical and empirical evidence that differences in strategy types may result in variation in favoured marketing information sources and procedure.

Design/methodology/approach – Depth interviews generated a series of scale items, which were combined with others derived from the literature in a questionnaire measuring strategy types, the roles of market research, and the characteristics of CRM systems. Responses were obtained from 240 senior marketing managers in Australia, and applied to the testing of five research propositions.

Findings – ANOVA found no differences in CRM usage among the strategy types. Variation was widespread, however, in four roles of traditional market research: enhancing strategic decision making, increasing usability of existing data, presenting plans to senior management, and achieving productivity and political outcomes.

Research limitations/implications – Future researchers using the Porter strategic types should separate “marketing differentiators” from “product differentiators” because they function and compete differently.

Practical implications – All organisations can benefit from CRM systems, but “marketing differentiators” exhibit a relatively higher usage of traditional market research. This is likely to be because they compete by creating softer product differences, while others do so on harder characteristics such as price or product functionality.

Originality/value – This is the first study to use the Porter types to explain differences between the roles and uses of market research and CRM within organisations.

UCP3 protein expression is lower in type I, IIa and IIx muscle fiber types of endurance-trained compared to untrained subjects

Uncoupling protein 3 (UCP3) is a muscle mitochondrial protein believed to uncouple the respiratory chain, producing heat and reducing aerobic ATP production. Our aim was to quantify and compare the UCP3 protein levels in type I, IIa and IIx skeletal muscle fibers of endurance-trained (Tr) and healthy untrained (UTr) individuals. UCP3 protein content was quantified using Western blot and immunofluorescence. Skeletal muscle fiber type was determined by both an enzymatic ATPase stain and immunofluorescence. UCP3 protein expression measured in skeletal muscle biopsies was 46% lower ( P=0.01) in the Tr compared to the UTr group. UCP3 protein expression in the different muscle fibers was expressed as follows; IIx>IIa>I in the fibers for both groups ( P<0.0167) but was lower in all fiber types of the Tr when compared to the UTr subjects ( P<0.001). Our results show that training status did not change the skeletal muscle fiber hierarchical UCP3 protein expression in the different fiber types. However, it affected UCP3 content more in type I and type IIa than in the type IIx muscle fibers. We suggest that this decrease may be in relation to the relative improvement in the antioxidant defense systems of the skeletal muscle fibers and that it might, as a consequence, participate in the training induced improvement in mechanical efficiency.

Expression of uncoupling protein-3 subsarcolemmal and intermyofibrillar mitochondria of various mouse muscle types and its moduclation by fasting

Uncoupling protein-3 (UCP3) is a mitochondrial inner-membrane protein abundantly expressed in rodent and human skeletal muscle which may be involved in energy dissipation. Many studies have been performed on the metabolic regulation of UCP3 mRNA level, but little is known about UCP3 expression at the protein level. Two populations of mitochondria have been described in skeletal muscle, subsarcolemmal (SS) and intermyofibrillar (IMF), which differ in their intracellular localization and possibly also their metabolic role. To examine if UCP3 is differentially expressed in these two populations and in different mouse muscle types, we developed a new protocol for isolation of SS and IMF mitochondria and carefully validated a new UCP3 antibody. The data show that the density of UCP3 is higher in the mitochondria of glycolytic muscles (tibialis anterior and gastrocnemius) than in those of oxidative muscle (soleus). They also show that SS mitochondria contain more UCP3 per mg of protein than IMF mitochondria. Taken together, these results suggest that oxidative muscle and the mitochondria most closely associated with myofibrils are most efficient at producing ATP. We then determined the effect of a 24-h fast, which greatly increases UCP3 mRNA (16.4-fold) in muscle, on UCP3 protein expression in gastrocnemius mitochondria. We found that fasting moderately increases (1.5-fold) or does not change UCP3 protein in gastrocnemius SS or IMF mitochondria, respectively. These results show that modulation of UCP3 expression at the mRNA level does not necessarily result in similar changes at the protein level and indicate that UCP3 density in SS and IMF mitochondria can be differently affected by metabolic changes.

Fuels of the future : the challenge of new fuel types

Landscape disturbances associated with human activities result in many changes in vegetation structure and floristics. These changes include invasion of native vegetation by both introduced and native species, which leads to the development of 'new' vegetation types. These new vegetation types are often associated with greatly increased fuel loads, and increased levels of fire hazard. Two of these 'new' fuel types are dense thickets of woody weeds, such as Coyote Bush (Baccharis pilularis) and swards of exotic grasses with very high fuel loads, such as Buffel Grass (Cenchrus ciliaris) and Para Grass (Urochloa mutica). The 'new' fuel types which can now be recognized have significant implications for the accuracy of fire behaviour prediction and modelling. For example, modelling fire behaviour in areas invaded by exotic grasses in Australia is problematic, as current grassland fire behaviour models do not allow for the input ofthe high fuel loads associated with these invasive grasses. In forest, McArthur Forest Fire Danger Meters may not be appropriate for forests with significant levels of elevated fuels. Two case studies from southeastern Australia are discussed: the invasion of native vegetation in the urban interface by the woody shrub Burgan (Kunzea ericoides) and invasion of native grasslands by Phalaris (Phalaris aquatica).

Exploring the contribution of different types of cited materials to marketing knowledge over time : a citation analysis

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.

Global branding and strategic CSR : an overview of three types of complexity

Purpose – There is general agreement that global brands should ensure that they incorporate social responsibility. To do this properly, organisations must understand what it means to be socially responsible and how they can leverage their actions. The paper proposes consideration of three distinct areas: the range of social responsibility issues, what the organisations actually do and how to leverage those corporate social responsibility (CSR) actions. This paper seeks to conceptually develop these three areas of complexity – Issue, Organisational and Communication – as it is only after organisations understand these three areas that they can effectively leverage socially responsible activities in their brands.

Design/methodology/approach – This research undertakes a review and synthesis of the academic, practitioner and industry literature examining CSR and the brand, addressing the three areas of complexity – issue, organisational and communication.

Findings – The research finds that within these three areas of complexity there are a number of sub-issues that must be addressed if CSR is to be strategically integrated into a global brand. This includes sub-issues associated with social issue complexity (identification, heterogeneity, measurement, and interpretation); organizational complexity (overall corporate brand, multiple products and brands, functional activities, and supply chain); and communication complexity (intensity of action/positioning, communicating action, types of programs utilised, and integration issues.) It thus provides an agenda for future research.

Research limitations/implications – There is limited academic literature examining how global organisations incorporate CSR activities into their brand and the research proposes the issues that need to be considered when integrating CSR into branding strategy. Future research needs to be undertaken to explore the internal processes that global firms use to develop their CSR positioning strategies and some research propositions for future research are proposed. Additionally further exploration of each of the issues (and sub-issues) identified in this paper is warranted, and some suggestions are made for this.

Practical implications – The results of this study show that developing a CSR leveraged brand in a consistent way that is salient to all stakeholders is no simple task for global organisations. By considering the three areas of complexity developed here organisations will be able to better understand and align their activities in line with CSR related issues. Being global means that organisations will likely need to ensure they address the highest set of global expectations, as any lower level may be criticised as being less than appropriate.

Originality/value – The paper develops the sub-issues of issue, organisational and communication complexity associated with global brands' CSR activities. This strategic perspective goes beyond focusing on the tactical activities undertaken or the philosophical issue of whether CSR should be undertaken. The work therefore allows global organisations to look at CSR more strategically as a branding issue.
