Genetic correlation between resting metabolic rate and exploratory behaviour in deer mice (Peromyscus maniculatus)

According to the ‘pace-of-life’ syndrome hypothesis, differences in resting metabolic rate (RMR) should be genetically associated with exploratory behaviour. A large number of studies reported significant heritability for both RMR and exploratory behaviour, but the genetic correlation between the two has yet to be documented. We used a quantitative genetic approach to decompose the phenotypic (co)variance of several metabolic and behavioural measures into components of additive genetic, common environment and permanent environment variance in captive deer mice. We found significant additive genetic variance for two mass-independent metabolic measures (RMR and the average metabolic rate throughout the respirometry run) and two behavioural measures (time spent in centre and distance moved in a novel environment). We also detected positive additive genetic correlation between mass-independent RMR and distance moved (rA = 0.78 ± 0.23). Our results suggest that RMR and exploratory behaviour are functionally integrated traits in deer mice, providing empirical support for one of the connections within the pace-of-life syndrome hypothesis.

Seasonal- and sex-specific correlations between dispersal and exploratory behaviour in the great tit

While the importance of personality in explaining individual dispersal strategies is increasingly recognized, limited information is still available on how patterns of personality-dependent dispersal may develop, hampering our understanding of the ecological significance of behavioural dispersal syndromes. Here, we examine the relative importance of personality at different stages of dispersal in the great tit, by analysing the sex-specific relationship between exploratory behaviour (EB; quantified in a novel environment) and dispersal distances in different seasons over the course of the first year of life (summer, autumn, winter, and until the first breeding attempt). In females, we found that EB was an important predictor of dispersal distances in summer and autumn, but only a weak to moderate correlation remained for females captured in winter or for natal dispersal distances based on first breeding records. We obtained a contrasting pattern at the population level, whereby male (but not female) immigrants captured in summer and autumn had higher EB scores than locally born birds, while this was not the case in birds captured in winter and those recruited as breeders into the population. In addition to providing further evidence for the existence of a behaviour dispersal syndrome in birds, our results show that correlations between EB and dispersal appear strongest at the early stages of the dispersal process, rather than being developed gradually. These findings show the importance of analysing the effect of phenotypic attributes on dispersal across different stages of the dispersal phenomenon and in each sex separately.

Personality in captivity: more exploratory males reproduce better in an aviary population

The existence of animal personality is well-established across a wide range of species, with the majority of evidence for this being obtained from individuals held in captivity. However, there has been little work assessing the influence of commonly-measured personality traits on fitness, which is pertinent when the genetic basis of personality is considered. We measured whether the reproductive behaviour and success of zebra finches in a captive mixed-sex aviary environment was influenced by an aspect of their personality, their exploratory behaviour in a single-sex social aviary. We found that more exploratory males made a greater number of breeding attempts and raised more nestlings than less exploratory males. These results were not confounded by extra-pair paternity, which was not related to personality, or by the individuals that did not initiate any reproductive attempts at all. Our work provides evidence that attributes of personality may influence the degree to which individuals cope with, and thrive in a captive environment and this should be accounted for in both experimental design and the interpretation of results. Furthermore, this suggests that there may be selection on these traits as part of the domestication process.

Exploration strategies map along fast-slow metabolic and life-history continua in muroid rodents

1Personality is highly relevant to ecology and the evolution of fast–slow metabolic and life-history strategies. One of the most important personality traits is exploratory behaviour, usually measured on an animal introduced to a novel environment (e.g. open-field test).2Here, we use a unique comparative dataset on open-field exploratory behaviour of muroid rodents to test a key assumption of a recent evolutionary model, i.e. that exploration thoroughness is positively correlated to age at first reproduction (AFR). We then examine how AFR and exploratory behaviour are related to basal metabolic rate (BMR).3Inter-specific variation in exploratory behaviour was positively correlated with AFR. Both AFR and exploration behaviour were negatively correlated with BMR. These results remained significant when taking phylogeny into account.4We suggest that species occupying unproductive and unpredictable environments simultaneously benefit from high exploration, low BMR and delayed AFR because exploration increases the likelihood of finding scarce resources, whereas low BMR and delayed reproduction enhance survival during frequent resources shortages.5This study provides the first empirical evidence for a link between personality, life-history, phylogeny and energy metabolism at the inter-specific level. The superficial-thorough exploration continuum can be mapped along the fast–slow metabolic and life-history continua.

Corporate ethics and new technology: an exploratory investigation of advertising activity and world wide web usage

This study explores the ethical standards and behaviour of Australian advertisers and their usage of new technologies. Although corporate ethics has been an issue in the established media of television advertising for some time, there is little research about how companies are adapting in terms of ethics to the new communication technologies. The consumers’ “right to know” was used as a device to assess the ethical standards and behaviour of companies. Findings suggest that the WWW is not used as a means of communicating corporate ethical standards. Results indicate that the method of communicating requests for information does not influence the likelihood of receiving a response from a company. The results also show differences between the ethical standards and the ethical behaviour of those companies who do use the WWW to communicate ethical statements.

An exploratory investigation of attitudes toward cause-related marketing

This paper reports on a study concerning consumer perceptions of cause-related marketing in Australia, and seeks to identify a direct link between consumer attitudes toward donating to charity (pro-social behaviour) and corporate philanthropy, and attitudes toward cause-related marketing. After a discussion on the related literature, there follows discussion on the research
model employed, and the fmdings of he study. Among other fmdings, statistically significant relationships between attitudes toward charitable giving and attitudes toward cause-related marketing are in evidence. In this study, respondents express a preference for local causes, as opposed to national and international causes, and also demonstrate a preference for cause types similar to those that already receive the highest level of charitable donations. The paper concludes with a discussion of the limitations of the study and presents suggestions for future research.

Consumer complainants amongst internet users: an exploratory study with an agenda for further research

The Internet has had a greater impact on consumer behaviour than any other innovation in recent years. Previous research has identified certain demographic traits of consumer who complain yet these demographic triggers are markedly different to the demographic profile of Internet users. This leads to the generation of several research questions that need to be considered to enable the development of effective strategies that need to be implemented to deal with the issues raised by this most important group of stakeholders - the users.

An exploratory analysis of the factors that influence food choice among young women

Food sales represent a significant proportion of hospitality industry income; however, little research has been conducted into the factors that influence food purchasing behaviour. This study employed a sequential mixed method research design to identify the factors that influence food choice among 18-30-year-old females. The study is important because this age group has considerable spending power and has been found to have different consumption priorities to their male counterparts. While confirming the importance of previous studies, this study found that physical health, time, marketing, price, and the quality of food are major factors of influence in the purchasing and consumption decision.

Learning patterns in social skills training programs : an exploratory study

While Social Skills Training programs have been shown to improve the social skills of children with Disruptive Behaviour Disorders, the pattern of change in the participants’ learning during the training period remains unknown. Identifying this pattern could assist in determining whether more or less training hours are required to maximize the benefits of such programs within available resources. The current study aimed to replicate the social skills improvements found in previous research, and to explore the pattern of improvements in social knowledge and social performance that occurs during a Social Skills Training program. Two groups of eight males with behavioural problems attended 14 one-hour sessions of Social Skills Training. Multisources, multisettings and multimethods were used to measure social knowledge and social performance across five test phases. Multivariate analyses did not support previous findings showing overall improvements in social knowledge and social performance. Patterns of learning were not found to be consistent across different measures.

Exchange as a determinant in corporate citizenship : exploratory action research into the social construction of corporate citizenship

This study attempts to achieve two things. Firstly it contextualizes corporate citizenship drawing on scholarly, government, media, legal and business discourses which when viewed as a whole, reveals the importance of exchange as a central determinant in how all the major themes or subfields of corporate citizenship function and subsequently become valued within public discourse. Secondly, it reports on exploratory action research where I as a researcher occupied a central role in understanding and contributing towards how organizational settings socially construct and evolve corporate citizenship in real time through various exchange behaviour, drawing from four years field research within BP and its interactions with the external world. This research contributes to new knowledge by building a rare contextual understanding into how cultural change evolves over time within an organization, from its public face, through policy, down into employee and stakeholder reactions, including identifying the crucial role played by Cultural bridges’ in shifting entrenched organizational culture towards embracing new, more sustainable ways of doing business, and additionally how practitioners can legitimately act as a researcher in facilitating this process by assisting an organization to move from simple, transactional relationships to more sustainable integrated social, financial and environmental exchange between business and its broader context. Importantly, this research develops entirely new theoretical models for understanding the social application and commercial value of corporate citizenship to both business and society.

Australia's informal venture capitalists : an exploratory profile

In Australia, as elsewhere, finding and acquiring equity capital is one of the major problems facing start-up or growing entrepreneurial ventures. The informal venture capital market, comprising high net worth non-institutional private equity investors (or 'business angels') provides risk capital directly to new and growing businesses and has been shown to be considerably more significant than institutional providers as a source of finance for entrepreneurial businesses. Building upon research undertaken internationally, this study generated and evaluated data resulting from an investigation of 36 carefully screened Australian business angels. It focused upon three primary research questions: (i) Who are Australia's informal venture capitalists (business angels)? (ii) How do they behave? (iii) What are their investment criteria? The study initiates Australian angel research into the developing international continuum of informal venture capital research and can serve as the generator of empirically testable hypotheses for future research and theory development.

An exploratory survey of Australia's informal venture capitalists : a predicate to theory building in the context of international angel research

In Australia, as it is all over the world, finding and acquiring equity capital is one of the major problems facing entrepreneurs who are starting or growing entrepreneurial ventures. The informal venture capital market, made up of high net worth non-institutional private equity investors (or ‘business Angels’) provides risk capital directly to new and growing businesses and has been shown to be considerably more significant than institutional providers as a source of finance for entrepreneurial businesses. Building upon and comporting with Angel research undertaken overseas, this study generated and evaluated data resulting from an investigation of Australian business Angels which focused upon three primary research questions: (i) Who are Australia's Informal Venture Capitalists (Business Angels)? (ii) How do they behave? (iii) What are their investment criteria? Analysis of answers resulting from a survey of 36 carefully screened respondents produced a descriptive profile, depicted in twelve key graphs, of Australian Angels' identifying characteristics, patterns of investment behaviour and investment criteria. The study initiates Australian Angel research into the developing international continuum of formal Angel research and can serve as the generator of empirically sensible hypotheses for future research and theory development.

Towards an understanding of residents' pro-environmental behaviour

The aim of this research was to provide a clearer understanding of how personal domain factors relate to pro-environmental behaviour. This exploratory study used the New Ecological Paradigm (NEP) scale (Dunlap et aI., 2000) and Stern's value orientation scale (Stern et aI., 1995) to gauge values and attitudes and how they relate to the adoption of a range of sustainable household products and practices of Australian householders. The research confirms that holding a pro-environmental attitude as measured by the NEP score does not relate to adoption of sustainable behaviours. However, egoistic values can be related to the uptake of some high cost pro-environmental products. Further research should seek to provide a deeper understanding of the contextual reasons for adoption or non-adoption of specific proenvironmental behaviours.

Strain differences in coping behaviour, novelty seeking behaviour, and susceptibility to socially conditioned fear : a comparison between Wistar and Sprague Dawley rats

The aim of the current study was to generate socially conditioned fear in two different strains of rat (Wistar, W and Sprague Dawley, SD) using social conflict, in order to investigate whether the magnitude of the conditioned fear responses in each strain was related to behaviour exhibited prior to or during fear induction (i.e. social conflict). On day one of the study, all intruders were assessed for exploratory activity in a novel environment. Twenty four hours following the novel environment test the locomotor activity of the intruders was assessed, while they underwent a single familiarisation exposure to the arena in which the conflict was subsequently to occur in. Twenty-four hours following familiarisation, intruders underwent either a 10 min social conflict or sham conflict session. One day later we examined the response of the intruders when they were returned to the vacant resident's cage. Upon return to the conflict context, we examined the intruder's ultrasonic distress vocalisations and the extent to which locomotor activity was inhibited. We found that W rats displayed significantly more immobility (i.e. conditioned fear) upon return to context than did SD rats (p < 0.05). Importantly, we observed that the differences in the two strains behaviour upon return to context appeared to be related to their quite different patterns of coping behaviour. The results of the current study indicate that preclinical between-strain comparisons potentially have much to offer in regard to understanding the basis of resilience to social stress.
