At-sea associations in foraging little penguins

Prey distribution, patch size, and the presence of conspecifics are important factors influencing a predator's feeding tactics, including the decision to feed individually or socially. Little is known about group behaviour in seabirds as they spend most of their lives in the marine environment where it is difficult to observe their foraging activities. In this study, we report on at-sea foraging associations of little penguins (Eudyptula minor) during the breeding season. Individuals could be categorised as (1) not associating; (2) associating when departing from and/or returning to the colony; or (3) at sea when travelling, diving or performing synchronised dives. Out of 84 separate foraging tracks, 58 (69.0%) involved associations with conspecifics. Furthermore, in a total of 39 (46.4%), individuals were found to dive during association and in 32 (38.1%), individuals were found to exhibit synchronous diving. These behaviours suggest little penguins forage in groups, could synchronise their underwater movements and potentially cooperate to concentrate their small schooling prey.

Unhealthy food, integrated marketing communication and power: a critical analysis

Public health advocates have repeatedly highlighted parallels between food marketing and childhood obesity. Yet existing literature has not explored the connection between the promotion of unhealthy foods and beverages, certain characteristics of integrated marketing communication (IMC) and the power of multinational food and beverage companies. This is problematic because IMC represents the dominant marketing paradigm in use today. This article draws on critical theory and literature from across public health, marketing, business and related fields. By focusing on macro-level antecedents and interactions, this discussion highlights a previously unarticulated dimension of the promotion of unhealthy foods and beverages to children and adolescents. In doing so, this discussion aims to generate greater recognition of the broader environmental circumstances and processes that surround food marketing tactics and their consequences for public health nutrition. This perspective will also contribute to an expanded understanding of unhealthy food marketing and its unintended consequences, among an audience of nutrition, public health and policy communities.

Adult education and radical habitus in an environmental campaign: learning in the coal seam gas protests in Australia

Summary: This paper examines the adult learning dimensions of protestors as they participate in a campaign to stop coal seam gas exploration in Gippsland in Central Victoria, Australia. On a global level, the imposition of coal seam gas exploration by governments and mining companies has been the trigger for movements of resistance from environmental groups. They are concerned about the impact of mining on their land, food and water supplies. In central Gippsland a group of ‘circumstantial activists’ comprised of farmers, tree changers and other local residents are campaigning against coal seam gas exploration. This unlikely coalition of environmental action groups has made effective use of a variety of community education strategies. This paper commences by outlining some of the key literature on learning and activism drawing on the education tradition of adult learning. We then draw on key concepts from Bourdieu’s writing on ‘habitus’ and ‘field’ to analyse the data from this research. We outline some of the learning practices of activists; through their involvement in this campaign, and the knowledge and skills they gain as they develop a feel for the game of protest. We argue circumstantial activists learn both formally and informally in the social environment of campaigning. Of particular interest is the role of more experienced activists from Friends of the Earth (FOE), a non-government organisation (NGO), as they pass on knowledge, experience, tactics and strategies to the novice and less experienced activists in this community campaign. We explore some of the contradictions of the protestors’ identification as activists using Bourdieu’s concepts of ‘doxa’ and ‘Ilusio’. The paper concludes by arguing learning in activism is a rich tradition of adult education and practice. However, Bourdieu’s writing on field and habitus makes an added contribution to interpreting the learning that occurs in the social space of a campaign or social movement.

Performance analysis and prediction in triathlon

Performance in triathlon is dependent upon factors that include somatotype, physiological capacity, technical proficiency and race strategy. Given the multidisciplinary nature of triathlon and the interaction between each of the three race components, the identification of target split times that can be used to inform the design of training plans and race pacing strategies is a complex task. The present study uses machine learning techniques to analyse a large database of performances in Olympic distance triathlons (2008–2012). The analysis reveals patterns of performance in five components of triathlon (three race “legs” and two transitions) and the complex relationships between performance in each component and overall performance in a race. The results provide three perspectives on the relationship between performance in each component of triathlon and the final placing in a race. These perspectives allow the identification of target split times that are required to achieve a certain final place in a race and the opportunity to make evidence-based decisions about race tactics in order to optimise performance.

Corporate social responsibility programs of big food in Australia: a content analysis of industry documents

OBJECTIVE: To examine Corporate Social Responsibility (CSR) tactics by identifying the key characteristics of CSR strategies as described in the corporate documents of selected 'Big Food' companies. METHODS: A mixed methods content analysis was used to analyse the information contained on Australian Big Food company websites. Data sources included company CSR reports and web-based content that related to CSR initiatives employed in Australia. RESULTS: A total of 256 CSR activities were identified across six organisations. Of these, the majority related to the categories of environment (30.5%), responsibility to consumers (25.0%) or community (19.5%). CONCLUSIONS: Big Food companies appear to be using CSR activities to: 1) build brand image through initiatives associated with the environment and responsibility to consumers; 2) target parents and children through community activities; and 3) align themselves with respected organisations and events in an effort to transfer their positive image attributes to their own brands. IMPLICATIONS: Results highlight the type of CSR strategies Big Food companies are employing. These findings serve as a guide to mapping and monitoring CSR as a specific form of marketing.

Don't eat that, you'll get fat! Exploring how parents and children conceptualise and frame messages about the causes and consequences of obesity

Family interactions about weight and health take place against the backdrop of the wider social discourse relating to the obesity epidemic. Parents (and children) negotiate complex and often contradictory messages in constructing a set of beliefs and practices around obesity and weight management. Despite this, very little research attention has been given to the nature of family-unit discourse on the subject of body weight and it's potential influence on the weight-related behaviours of family members. This includes the broad influence that dominant socio-cultural discourses have on family conceptualisations of weight and health. Using in-depth qualitative interviews with 150 family 'groups' comprised of at least one parent and one child in Victoria and South Australia, we explored how parents and children conceptualise and discuss issues of weight- and health-related lifestyle behaviours. Data were analysed using Attride-Stirling's (2001) thematic network approach. Three thematic clusters emerged from the analysis. First, both parents and children perceived that weight was the primary indicator of health. However, parents focused on the negative physical implications of overweight while children focused on the negative social implications. Second, weight and lifestyle choices were highly moralised. Parents saw it as their responsibility to communicate to children the 'dangers' of fatness. Children reported that parents typically used negatively-framed messages and scare tactics rather than positively-framed messages to encourage healthy behaviours. Third was the perception among parents and children that if you were thin, then eating habits and exercise were less important, and that activity could provide an antidote to food choices. Results suggest that both parents and children are internalising messages relating to obesity and weight management that focus on personal responsibility and blame attribution. These views reflect the broader societal discourse, and their consolidation at the family level is likely to increase their potency and make them resistant to change.

Gambling advocacy: lessons from tobacco, alcohol and junk food

OBJECTIVE: To explore the attitudes and opinions of public health experts in gambling and related unhealthy commodity industries towards the tactics used by the gambling industry to prevent reform and the advocacy responses to these tactics. METHODS: In-depth interviews (30-60 minutes) with a convenience sample of 15 public health experts and stakeholders with a public health approach to gambling (n=10), or other unhealthy commodity industries (food, alcohol, tobacco, n=5). RESULTS: Participants described the influences of political lobbying and donations on public policy, and industry framing of problem gambling as an issue of personal responsibility. Industry funding of, and influence over, academic research was considered to be one of the most effective industry tactics to resist reform. Participants felt there was a need to build stronger coalitions and collaborations between independent academics, and to improve the utilisation of media to more effectively shift perceptions of gambling harm away from the individual and towards the product. CONCLUSIONS AND IMPLICATIONS: Gambling industry tactics are similar to the tactics of other unhealthy commodity industries. However, advocacy initiatives to counter these tactics in gambling are less developed than in other areas. The formation of national public health coalitions, as well as a strong evidence base regarding industry tactics, will help to strengthen advocacy initiatives.

Shaping pathways to gambling consumption? An analysis of the promotion of gambling and non-gambling activities from gambling venues

Background: In Australia, venues which provide gambling activities also provide activities that are utilised by families and children. However, there has been limited theoretical or empirical discussion about whether engagement with non-gambling activities may play a role in shaping pathways to current or future engagement in gambling within these environments. We examined marketing tactics for non-gambling and gambling activities in Clubs. Using this data, we propose a conceptual model to test the role of non-gambling activities within gambling environments in shaping gambling attitudes and consumption intentions.

Methods: This study used a mixed method interpretive content analysis to review the marketing activities on the websites of a sample of 65 registered Clubs in New South Wales, Australia. We identified the extent and nature of techniques used to market gambling and non-gambling activities, particularly non-gambling activities directed towards families and children.

Results: Clubs use various marketing tactics to appeal to families and encourage parents to bring their children into venues. We hypothesise that marketing aimed at bringing children and families into gambling environments may play a role in shaping children’s and adults perceptions of these environments and may be influential in the development of a pathway that increases the likelihood that children will continue to visit these environments as adults, and subsequently the extent to which they engage in gambling later in life.

Conclusions: Future research should explore how the presence of family-friendly activities in Clubs and other venues with gambling activities may play a role in shaping future gambling attitudes and behaviours.

Response to Islamophobia in the Arabic Islamic discourse: a critical discourse analysis

In the aftermath of September 11, Muslim scholars made numerous attempts to explain Islamophobia from the Islamic perspective; they presented arguments that are not addressed in the Western narrative. Two texts in Arabic by the prominent Muslim preacher, Mohammad Hassan and by the Muslim orator Fadhel Sliman are analysed from a Critical Discourse Analysis (CDA) viewpoint. This analysis aims to demonstrate how language is inextricably linked with ideology. This paper demonstrates that textual strategies in the Arabic Islamic discourse and their ideological implications show distinct characteristics some of which add to the present literature on discourse. The aim of the chosen texts is to educate and create solidarity between the speakers and the audience in fighting Islamophobia. The reliance of the speakers on tactics such as quoting from the Holy Qur’ān and ḥadīth to defend Islam, and choice of words and sentence structures may instigate discussions about the persuasive power of the Arabic Islamic narrative.

Life-history and spatial determinants of somatic growth dynamics in Komodo dragon populations

Somatic growth patterns represent a major component of organismal fitness and may vary among sexes and populations due to genetic and environmental processes leading to profound differences in life-history and demography. This study considered the ontogenic, sex-specific and spatial dynamics of somatic growth patterns in ten populations of the world's largest lizard the Komodo dragon (Varanus komodoensis). The growth of 400 individual Komodo dragons was measured in a capture-mark-recapture study at ten sites on four islands in eastern Indonesia, from 2002 to 2010. Generalized Additive Mixed Models (GAMMs) and information-theoretic methods were used to examine how growth rates varied with size, age and sex, and across and within islands in relation to site-specific prey availability, lizard population density and inbreeding coefficients. Growth trajectories differed significantly with size and between sexes, indicating different energy allocation tactics and overall costs associated with reproduction. This leads to disparities in maximum body sizes and longevity. Spatial variation in growth was strongly supported by a curvilinear density-dependent growth model with highest growth rates occurring at intermediate population densities. Sex-specific trade-offs in growth underpin key differences in Komodo dragon life-history including evidence for high costs of reproduction in females. Further, inverse density-dependent growth may have profound effects on individual and population level processes that influence the demography of this species.

Kinanthropometric differences between 1997 World championship junior elite and 2011 national junior elite triathletes

OBJECTIVES: In 1997, anthropometry measures were made to determine the body size and shapes of both senior and junior elite triathletes. Since then, the junior event distance has changed and the optimal morphology of participants may have evolved. Thus the objective of this study was to compare the morphology of 1997 World championship junior elite triathlon competitors with junior elite competitors in 2011. DESIGN: Comparative study of junior elite triathlete kinanthropometry. METHODS: Twenty-nine males and 20 females junior elite competitors in the 1997 Triathlon World Championships underwent 26 anthropometric measurements. Results were compared with 28 male and 14 female junior elite triathletes who competed in the 2011 Australian National Junior Series, as qualifying for 2011 Triathlon World Championships. Comparisons were made on the raw scores, as well as somatotype, and body proportional scores. RESULTS: Both male and female junior elite triathletes in the 2011 group were significantly more ectomorphic than their 1997 counterparts. The 2011 triathletes were also proportionally lighter, with significantly smaller flexed arm and thigh girths, and femur breadths. The 2011 males recorded significantly longer segmental lengths and lower endomorphy values than the 1997 junior males. CONCLUSIONS: Junior elite triathlete morphology has evolved during the past 14 years possibly as a result of changing race distance and race tactics, highlighting the importance of continually monitoring and updating such anthropometric data.

Activity profiles and demands of seasonal and tournament basketball competition

UNLABELLED: Competition-specific conditioning for tournament basketball games is challenging, as the demands of tournament formats are not well characterized. PURPOSE: To compare the physical, physiological, and tactical demands of seasonal and tournament basketball competition and determine the pattern of changes within an international tournament. METHODS: Eight elite junior male basketball players (age 17.8 ± 0.2 y, height 1.93 ± 0.07 m, mass 85 ± 3 kg; mean ± SD) were monitored in 6 seasonal games played over 4 mo in an Australian second-division national league and in 7 games of an international under-18 tournament played over 8 days. Movement patterns and tactical elements were coded from video and heart rates recorded by telemetry. RESULTS: The frequency of running, sprinting, and shuffling movements in seasonal games was higher than in tournament games by 8-15% (99% confidence limits ± ~8%). Within the tournament, jogging and low- to medium-intensity shuffling decreased by 15-20% (± ~14%) over the 7 games, while running, sprinting, and high-intensity shuffling increased 11-81% (± ~25%). There were unclear differences in mean and peak heart rates. The total number of possessions was higher in seasonal than in tournament games by 8% (± 10%). CONCLUSIONS: Coaches should consider a stronger emphasis on strength and power training in their conditioning programs to account for the higher activity of seasonal games. For tournament competition, strategies that build a sufficient aerobic capacity and neuromuscular resilience to maintain high-intensity movements need to be employed. A focus on half-court tactics accounts for the lower number of possessions in tournaments.

Design and interpretation of anthropometric and fitness testing of basketball players

The volume of literature on fitness testing in court sports such as basketball is considerably less than for field sports or individual sports such as running and cycling. Team sport performance is dependent upon a diverse range of qualities including size, fitness, sport-specific skills, team tactics, and psychological attributes. The game of basketball has evolved to have a high priority on body size and physical fitness by coaches and players. A player's size has a large influence on the position in the team, while the high-intensity, intermittent nature of the physical demands requires players to have a high level of fitness. Basketball coaches and sport scientists often use a battery of sport-specific physical tests to evaluate body size and composition, and aerobic fitness and power. This testing may be used to track changes within athletes over time to evaluate the effectiveness of training programmes or screen players for selection. Sports science research is establishing typical (or 'reference') values for both within-athlete changes and between-athlete differences. Newer statistical approaches such as magnitude-based inferences have emerged that are providing more meaningful interpretation of fitness testing results in the field for coaches and athletes. Careful selection and implementation of tests, and more pertinent interpretation of data, will enhance the value of fitness testing in high-level basketball programmes. This article presents reference values of fitness and body size in basketball players, and identifies practical methods of interpreting changes within players and differences between players beyond the null-hypothesis.

Rise of the machines: a critical consideration of automated leadership decision making in organizations

Machines are increasingly becoming a substitute for human skills and intelligence in a number of fields where decisions that are crucial to group performance have to be taken under stringent constraints—for example, when an army contingent has to devise battlefield tactics or when a medical team has to diagnose and treat a life-threatening condition or illness. We hypothesize a scenario where similar machine-based intelligent technology is available to support, and even substitute human decision making in an organizational leadership context. We do not engage in any metaphysical debate on the plausibility of such a scenario. Rather, we contend that given what we observe in several other fields of human decision making, such a scenario may very well eventuate in the near future. We argue a number of “positives” that can be expected to emerge out of automated group and organizational leadership decision making. We also posit several anti-theses—“negatives” that can also potentially emerge from the hypothesized scenario and critically consider their implications. We aim to bring leadership and organization theorists, as well as researchers in machine intelligence, together at the discussion table for the first time and postulate that while leadership decision making in a group/organizational context could be effectively delegated to an artificial-intelligence (AI)-based decision system, this would need to be subject to the devising of crucial safeguarding conditions.

Mechanisms of influence: alcohol industry submissions to the inquiry into fetal alcohol spectrum disorders

INTRODUCTION AND AIMS: Industry groups with vested interests in policy regularly work to protect their profits via the endorsement of ineffective voluntary regulation and interventions, extensive lobbying activity and minimising the health impact of consumption behaviours. This study aims to examine all alcohol industry submissions to the Australian House of Representatives Standing Committee on Social Policy and Legal Affairs into Fetal Alcohol Spectrum Disorders (FASD), to assist in understanding how those with vested interests contribute to policy development. The analysis aims to document the strategies and arguments used by alcohol industry bodies in their submissions and to compare these with known strategies of vested-interest groups. DESIGN AND METHODS: All 92 submissions to the Inquiry were screened to include only those submitted by alcohol industry bodies (five submissions). Content domains were derived based on the major themes emerging from the industry submissions and on common vested-interest behaviours identified in previous literature. RESULTS: The following content categories were identified: Concerns about FASD; Current industry activities and FASD prevention; Value of mandatory warning labels; and Credibility of independent public health researchers and organisations. DISCUSSION AND CONCLUSIONS: Alcohol industry submissions sought to undermine community concern, debate the evidence, promote ineffective measure which are no threat to the profit margins and attack independent health professionals and researchers. In doing so, their behaviour is entirely consistent with their responses to other issues, such as violence and chronic health, and copies the tactics employed by the tobacco industry.
