The impact of general and carbon-related environmental knowledge on attitudes and behaviour of US consumers

Global warming and carbon emissions have gained international attention. However, it would appear that consumers are still unclear about what it encompasses and how it relates to their individual behaviour. Using the Theory of Reasoned Action (TRA) as a guiding framework, this study presents a structural equation model that tests the relationships between carbon and environmental knowledge, environmental attitude and behaviour using a sample of US consumers. The findings of the research suggest that a positive relationship was found between general and carbon-specific knowledge, attitude towards the environment, and general and carbon-specific behaviours. Therefore, general and carbon-specific environmental behaviours are related and may be driven by general attitudes and knowledge (i.e. both carbon-specific and general environmental knowledge). The implications of the study would suggest that marketers, working in tandem with government policymakers, need to focus efforts on developing consumers’ knowledge about specific sub-issues, such as global warming. However, additional research needs to be undertaken to develop marketing communication that accurately reflects the environmental impact of consumption behaviour, thereby allowing for considered consumption.

Long-term species, sexual and individual variations in foraging strategies of fur seals revealed by stable isotopes in whiskers

Background: Individual variations in the use of the species niche are an important component of diversity in trophic interactions. A challenge in testing consistency of individual foraging strategy is the repeated collection of information on the same individuals.

Methodology/Principal Findings: The foraging strategies of sympatric fur seals (Arctocephalus gazella and A. tropicalis) were examined using the stable isotope signature of serially sampled whiskers. Most whiskers exhibited synchronous delta C-13 and delta N-15 oscillations that correspond to the seal annual movements over the long term (up to 8 years). delta C-13 and delta N-15 values were spread over large ranges, with differences between species, sexes and individuals. The main segregating mechanism operates at the spatial scale. Most seals favored foraging in subantarctic waters (where the Crozet Islands are located) where they fed on myctophids. However, A. gazella dispersed in the Antarctic Zone and A. tropicalis more in the subtropics. Gender differences in annual time budget shape the seal movements. Males that do not perform any parental care exhibited large isotopic oscillations reflecting broad annual migrations, while isotopic values of females confined to a limited foraging range during lactation exhibited smaller changes. Limited inter-individual isotopic variations occurred in female seals and in male A. tropicalis. In contrast, male A. gazella showed large inter-individual variations, with some males migrating repeatedly to high-Antarctic waters where they fed on krill, thus meaning that individual specialization occurred over years.

Conclusions/Significance: Whisker isotopic signature yields unique long-term information on individual behaviour that integrates the spatial, trophic and temporal dimensions of the ecological niche. The method allows depicting the entire realized niche of the species, including some of its less well-known components such as age-, sex-, individual- and migration-related changes. It highlights intrapopulation heterogeneity in foraging strategies that could have important implications for likely demographic responses to environmental variability.

Fishing directly selects on growth rate via behaviour: implications of growth-selection that is independent of size

Size-selective harvest of fish and crustacean populations has reduced stock numbers, and led to reduced growth rates and earlier maturation. In contrast to the focus on size-selective effects of harvest, here, we test the hypothesis that fishing may select on life-history traits (here, growth rate) via behaviour, even in the absence of size selection. If true, then traditional size-limits used to protect segments of a population cannot fully protect fast growers, because at any given size, fast-growers will be more vulnerable owing to bolder behaviour. We repeatedly measured individual behaviour and growth of 86 crayfish and found that fast-growing individuals were consistently bold and voracious over time, and were subsequently more likely to be harvested in single- and group-trapping trials. In addition, there was some indication that sex had independent effects on behaviour and trappability, whereby females tended to be less active, shyer, slower-growing and less likely to be harvested, but not all these effects were significant. This study represents, to our knowledge, the first across-individual support for this hypothesis, and suggests that behaviour is an important mechanism for fishing selectivity that could potentially lead to evolution of reduced intrinsic growth rates.

A self-representation analysis of the effects of individualist-collectivist interactions within organizations in individualistic cultures

Purpose – Increasingly, organizations in the Asia-Pacific region are recognizing the importance of cross-cultural management to the sustainability of their competitive edge. Although the literature is replete with cross-cultural studies of individualism and collectivism, little information is available on the factors that foster effective individualist–collectivist interaction (ICI) within organizations. This paper attempts to provide a theoretical description of individualists and collectivists at the individual
level of analysis, which offers specific testable hypotheses about the effect of self-representation on prejudice between individualists and collectivists (ICs).

Design/methodology/approach – In this paper, a theoretical model is presented in which intergroup prejudices and interpersonal prejudices mediate the effects of ICI and bicultural orientation toward cross-cultural experiences and, in which, the dissimilarity openness of the climate
moderates the level and outcome of prejudices flowing from ICI.

Findings – The model depicts that the outcomes of ICI are mediated by the intergroup prejudices of collectivists and the interpersonal prejudices of individualists, which are moderated by the extent of diversity-oriented HRM policies and practices and individuals’ orientation to cross-cultural experiences. When workforces become culturally diverse, organizations should modify HRM practices to enable the full use of the range of skills and talents available from the diversity, and to ensure affective and behavioral costs are minimized. As globalization and international competition will continue to increase, organizations including those in the Asia-Pacific region, should seriously reevaluate their HRM policies to adapt and take advantage of an increasingly culturally diverse workforce.

Originality/value – The model provides a useful basis upon which organization researchers and practitioners can base their respective agendas.

The global village: online cross-cultural communication and HRM

Purpose – The purpose of this paper is to examine relational and task dimension of online communication and the associated emotional experience.

Design/methodology/approach – This paper examines four categories of work outcomes: emotional experiences of work, work attitudes, work dynamics and work behaviours; and links each to the cross-cultural online communication context.

Findings – It was found that diversity-oriented HRM can reduce the cultural fault-lines betweenindividualist and collectivist (IC) cultures, and thereby positively moderate the relationship between cross-cultural online communication and affective, cognitive and behavioural outcomes.

Practical implications – Diversity-oriented HRM can capitalize on an organisation’s cultural diversity and avoid cross-cultural misunderstandings. In a more practical sense, the research purports that combined use of IC HRM practices can produce greater efficiency and effectiveness in
online communications worldwide.

Originality/value – The paper provides an insight into the potential implications of increased use of information technology on cross-cultural communication, and human resource management. The significance of diversity-oriented human resource management in managing these implications is also highlighted.

Banding and radio-tracking juvenile powerful owls in Melbourne, Victoria : trials and tribulations

The Powerful Owl (Ninox strenua) is Australia's largest owl. Considering their large size they are a very cryptic species, with limited sexual dimorphism, silent fight and a highly camouflaged presence amongst secluded canopy vegetation. These features enable Powerful Owl presence to often go unnoticed and even for the trained eye, extremely difficult to study. Our research has focused on monitoring the behaviour of individual Powerful Owls in urban Melbourne, Australia.
The leg banding of Powerful Owls is a somewhat contentious issue in Australia and here we report on the suitability of different types of legs bands placed on the tarsus of juvenile Powerful Owls. There has been some debate over the band size that should be used and the consequent effects bands may pose for the owls as they mature. We also investigate the usefulness of bands as a technique to identify Powerful Owls once they have dispersed from the natal territory.
Radio-tracking juvenile Powerful Owls was also undertaken during this study, primarily to determine individual behaviour from post fledging until dispersal. This is the first study in Australia to attempt radio-tracking juvenile Powerful Owls and the results from this research highlight behavioural characteristics, mortality rates post fledging and dispersal movements for the twelve months post fledging.
Overall we found that aluminium legs bands are a useful tool for individual identification of juvenile Powerful Owls post fledgling, however, their presence is somewhat difficult to determine on mature adults as the tarsus feathers tend to cover the band and make vision from the ground difficult. Aluminium leg bands are also useful as an identification tool for deceased birds. Leather leg bands are more suitable than aluminium bands when attaching radio-transmitters as these provide more flexibility and can be removed by the owl if they become irritating.
Radio-tracking juvenile Powerful Owls provided invaluable information relating to juvenile behaviour and movements, showing that juveniles actually remain in territories adjacent to their natal territory for the twelve months post fledging. This information is vital for the successful conservation of this species, particularly in relation to habitat conservation and home-range modelling.

Business ethics : practical proposals

While most people agree that the inculcation of ethical awareness is desirable, the means of stimulating this awareness vary among companies, industries and cultures. The fundamental question surrounding the difference between social responsibility and ethics is addressed. Guidelines for establishing ethical priorities from both the individual, group and organisational perspectives are provided.

Scapegoating, self-confidence and risk comparison : the functionality of risk neutralisation and lay epidemiology by injecting drug users

This paper investigates the competing rationalities of scientific and lay epidemiology and how the tension between the two impacts on the efficacy of health promotion messages for injecting drug users (IDUs). It proposes that behaviours, which may be difficult to understand when viewed at an individual level, are, in fact, rational within particular cultural contexts. The study used qualitative semi-structured interviews with 60 heroin users. A number of different types of risk neutralisation were observed in this group of interviewees, including: scapegoating, self-confidence and risk comparison. Interviewees commonly used lay epidemiology to justify and rationalise their risk neutralisation strategies. The paper provides concrete examples of the ways in which this group of IDUs neutralise risk through the use of these strategies. The findings illustrate how many of the psychological constructs surrounding the perception of risk which focus on individual behaviour are fundamentally simplistic and often unhelpful in understanding the behaviours of this group of people. It is concluded that some ‘risk’ behaviours are often functional and rational within the context of prohibitionist drug policies which create an environment in which the IDU often has little real agency to reduce the risks associated with their drug use.

Collaborative improvement : interplay but not a game

Collaboration literally means working together. Collaborative improvement is an extension of continuous improvement and can be defined as a purposeful inter-company interactive process that focuses on continuous incremental innovation aimed at enhancing the collaboration’s overall performance. Developing collaborative improvement is a protracted and difficult process. Previous research has identified a number of factors affecting that process and suggested that it is not so much the individual factors, but rather their interplay that determines the successful development of collaborative improvement. This article reports research aimed at developing a deeper understanding of that interplay. Ten relationships between ten factors are presented and discussed. It appears that vision, approach, trust and commercial reality are the strongest factors. These factors are, however, influenced by, or affect the other factors, notably national culture, partner characteristics and competences, the use of power, individual behaviour and commitment. The way this interplay develops varies from case to case and has great influence on the development of collaborative improvement.

Relationships, the role of individuals and knowledge flows in the internationalization of service firms

This article develops a new conceptual model of knowledge flows within international service firms. Our model takes explicit account of the critical role of relationships and the individual as being central to the process of knowledge transfer for service firms. The model is then validated with data collected from five international service firms using critical event analysis techniques. The findings reinforce our contention that the individual plays a critical role in the process of knowledge transfer and that relationships form an integral part of this process. The implications of this finding are also discussed.

Interventions designed to limit gestational weight gain: a systematic review of theory and meta-analysis of intervention components

Limiting gestational weight gain (GWG) to recommended levels is important to optimize health outcomes for mother and baby. Surprisingly, a recent review revealed that theory-based interventions to limit GWG were less effective than interventions that did not report a theory-base; however, strict criteria were used to identify theory-informed studies. We extended this review and others by systematically evaluating the theories of behaviour change informing GWG interventions using a generalized health psychology perspective, and meta-analysing behaviour change techniques reported in the interventions. Interventions designed to limit GWG were searched for using health, nursing and psychology databases. Papers reporting an underpinning theory were identified and the CALO-RE taxonomy was used to determine individual behaviour change techniques. Nineteen studies were identified for inclusion. Eight studies were informed by a behaviour change theory; six reported favourable effects on GWG. Overall, studies based on theory were as effective as non–theory-based studies at limiting GWG. Furthermore, the provision of information, motivational interviewing, behavioural self-monitoring and providing rewards contingent on successful behaviour appear to be key strategies when intervening in GWG. Combining these behaviour change techniques with dietary interventions may be most effective. Future research should focus on determining the exact combination of behaviour change techniques, or which underpinning theories, are most useful for limiting GWG.

The effects of familiarity and group size on mating preferences in the guppy, Poecilia reticulata

In recent years, it has become evident that frequency dependence in the attractiveness of a particular phenotype to mates can contribute to the maintenance of polymorphism. However, these preferences for rare and unfamiliar male phenotypes have only been demonstrated in small, controlled experiments. Here, we tested the preference for unfamiliar mates in groups of six to 96 individuals over 13 days, in the guppy (Poecilia reticulata). We observed individual behaviour in situ to test whether fish discriminate two unfamiliar individuals among many familiar ones. We found that unfamiliar males and females were preferred over the familiar fishes in all groups and that this effect decayed over time. Increasing group sizes and levels of sexual activity did not hamper the preference for unfamiliar mates, providing further support for the role of frequency dependent mate choice in the maintenance of trait polymorphism in natural populations.

The effect of obesity prevention interventions according to socioeconomic position: a systematic review

Obesity prevention is a major public health priority. It is important that all groups benefit from measures to prevent obesity, but we know little about the differential effectiveness of such interventions within particular population subgroups. This review aimed to identify interventions for obesity prevention that evaluated a change in adiposity according to socioeconomic position (SEP) and to determine the effectiveness of these interventions across different socioeconomic groups. A systematic search of published and grey literature was conducted. Studies that described an obesity prevention intervention and reported anthropometric outcomes according to a measure of SEP were included. Evidence was synthesized using narrative analysis. A total of 14 studies were analysed, representing a range of study designs and settings. All studies were from developed countries, with eight conducted among children. Three studies were shown to have no effect on anthropometric outcomes and were not further analysed. Interventions shown to be ineffective in lower SEP participants were primarily based on information provision directed at individual behaviour change. Studies that were shown to be effective in lower SEP participants primarily included community-based strategies or policies aimed at structural changes to the environment. Interventions targeting individual-level behaviour change may be less successful in lower SEP populations. It is essential that our efforts to prevent obesity do not leave behind the most disadvantaged members of society.

A snapshot of the scope of obesity prevention practice in Australia.

Community-based initiatives (CBIs) that build capacity and promote healthy environments hold promise for preventing obesity and non-communicable disease, however their characteristics remain poorly understood and lessons are learned in isolation. This limits understanding of likely effectiveness of CBIs; the potential for actively supporting practice; and the translation of community-based knowledge into policy. Building on an initial survey (2010), an online survey was launched (2013) with the aim to describe the reach and characteristics of Australian CBIs and identify and evaluate elements known to contribute to best practice, effectiveness and sustainability. Responses from 104 CBIs were received in 2013. Geographic location generally reflected population density in Australia. Duration of CBIs was short-term (median 3 years; range 0.2-21.0 years), delivered mostly by health departments and local governments. Median annual funding had more than doubled since the 2010 survey, but average staffing had not increased. CBIs used at least two strategy types, with a preference for individual behaviour change strategies. Targeting children was less common (31%) compared with the 2010 survey (57%). Logic models and theory were used in planning, but there was low use of research evidence and existing prevention frameworks. Nearly, all CBIs had an evaluation component (12% of budget), but dissemination was limited. This survey provides information on the scope and varied quality of the current obesity prevention investment in Australia. To boost the quality and effectiveness of CBIs, further support systems may be required to ensure that organizations adopt upstream, evidence-informed approaches; and integrate CBIs into systems, policies and environments.
