Deliberate Play

The developmental histories of 32 players in the Australian Football League (AFL), independently classified as either expert or less skilled in their perceptual and decision-making skills, were collected through a structured interview process and their year-on-year involvement in structured and deliberate play activities retrospectively determined. Despite being drawn from the same elite level of competition, the expert decision-makers differed from the less skilled in having accrued, during their developing years, more hours of experience in structured activities of all types, in structured activities in invasion-type sports, in invasion-type deliberate play, and in invasion activities from sports other than Australian football. Accumulated hours invested in invasion-type activities differentiated between the groups, suggesting that it is the amount of invasion-type activity that is experienced and not necessarily intent (skill development or fun) or specificity that facilitates the development of perceptual and decision-making expertise in this team sport.

Purpose:To compare a novel sprint test on a cycle ergometer with a countermovement-jump (CMJ) test for monitoring neuromuscular fatigue after Australian rules football match play.Methods:Twelve elite under-18 Australian rules football players (mean ± SD age 17.5 ± 0.6 y, stature 184.7 ± 8.8 cm, body mass 75.3 ± 7.8 kg) from an Australian Football League club’s Academy program performed a short sprint test on a cycle ergometer along with a single CMJ test 1 h prematch and 1, 24, and 48 h postmatch. The cycle-ergometer sprint test involved a standardized warm-up, a maximal 6-s sprint, a 1-min active recovery, and a 2nd maximal 6-s sprint, with the highest power output of the 2 sprints recorded as peak power (PP).Results:There were small to moderate differences between postmatch changes in cycle-ergometer PP and CMJ PP at 1 (ES = 0.49), 24 (ES = –0.85), and 48 h postmatch (ES = 0.44). There was a substantial reduction in cycle-ergometer PP at 24 h postmatch (ES = –0.40) compared with 1 h prematch.Conclusions:The cycle-ergometer sprint test described in this study offers a novel method of neuromuscular-fatigue monitoring in team-sport athletes and specifically quantifies the concentric component of the fatigue-induced decrement of force production in muscle, which may be overlooked by a CMJ test.

The Relationship

The present study was designed to explore the skill of recruiting in the professional Australian Football League, with a particular interest in the approach to decision making and information processing. The research design utilised semi-structured interviews and a survey instrument. A total of 12 participants comprised of 11 active head recruiters representing 11 Australian Football League Clubs, and one former expert Australian Football League recruiter undertook semi-structured, in-depth interviews to provide insight into recruitment decision making. Additionally, all participants completed a survey determining preferences for intuitive and deliberative decision-making styles. A model created represents the identification of four influential factors in the recruitment approach including (a) recruiter background; (b) recruiter attributes; (c) recruiter understanding of team needs and (d) recruiter–coach relationship. In particular, recruiters revealed that the style of decision making they use is influenced by the relationship with the head coach. Recruiting as a stand-alone position is not well understood. This work shows that both intuition and deliberation are used, the extent to which appears to be influenced by the recruiter–coach relationship. This work offers a strong base to further explore recruiting and talent identification in professional sport, and, particularly, how relationships influence decision style and performance.

The Impact

Background: Proxy decision makers often have to make decisions for people with advanced dementia. Their expectations regarding prescribed medications have the potential to influence prescription or withdrawal of medications. However, few studies to date have explored this. Aim: To explore proxy decision makers’ expectations of prescribed medications for people with advanced dementia and to consider how these change with changing goals of care and dementia progression. Design: This is a qualitative semi-structured interview study. Setting/participants: In total, 15 proxy decision makers of people with advanced dementia were recruited via general practitioners ( n = 9), Join Dementia Research ( n = 3) and the Alzheimer’s Society Northern Ireland ( n = 3). Results: Five key themes emerged: the role as advocate, attitudes to medicines and medicine taking, uncertainty over the benefit of anti-dementia medications, stopping medications, and communication and decision-making. Proxy decision makers desired more information about prescribed medicines, particularly the indications, benefits and risks of treatment. Despite uncertainty about the benefits of anti-dementia medications, proxy decision makers were reluctant for these medications to be withdrawn. Reluctance to stop other prescribed medicines was also expressed but reduced with changing goals of care and dementia progression. Although some proxy decision makers expected to be involved in medication-related decisions, the majority preferred to delegate these decisions to healthcare professionals. However, they expected to be informed of any medication-related decisions made. Conclusion: Proxy decision makers vary in terms of their desire for active involvement in the medication decision-making process. Healthcare professionals should facilitate proxy decision maker involvement if desired. Further research is required to consider the impact of proxy decision maker involvement in decision-making.

Purpose The purpose of this paper is to audit the efforts made around the support of indigenous players within the Australian Football League (AFL). Design/methodology/approach Content analysis of the publicly available information on websites of organizations associated with the AFL was undertaken to identify the extent of programs and policies around indigenous representation, inclusion, and development. Findings The AFL, as an organization, has a high percentage of indigenous players (employees) in comparison to the wider Australian workforce representation. Largely, indigenous representation within the AFL is merit based, prioritized on an individual’s ability to play football at an elite level. The website audit identified a number of inconsistencies in the public personas portrayed by the AFL and organizations aligned to it such as the AFL Players Association and clubs. The findings raise a number of questions for future research. Research limitations/implications The main limitation is that the website audit represents a very small insight into the current situation and does not provide a depth of analysis into the circumstances around indigenous inclusion within the AFL. The audit also is very focused on one sporting organization which may or may not be representative of the sport industry. Originality/value The research introduces a number of questions for future discovery.

In sport, decision-making research has identified consistent results among the three variations of the recognition primed decision (RPD) model. Despite the fact that officials in sport are a key component of sports systems, previous research has explored the RPD model in players only. This paper addresses this by applying the RPD model to examine the decision making of umpires in Australian Rules football (Australian Football League [AFL]). Method: Audible communication instances of AFL field umpiring teams overseeing three games were transcribed. The data were coded into “decision moments”; each decision moment was classified into one of the three RPD model variations. Results: Within the 6,025 communication instances, 887 decision moments were identified. Of the decision moments, 78.70% were classified as Variation 1, 19.75% as Variation 2, and 1.35% as Variation 3. Discussion: The results demonstrate that AFL umpire decision making can be characterized by a similar RPD breakdown as that by players in sport. RPD variation in AFL umpiring is influenced by the game situation and the type of adjudication being made. The implications for research and practice are discussed, including extending the analysis to multirole officiating teams (e.g., soccer) and the provision of tailored decision-making training.

Purpose:The purpose of the study was to determine the reliability of yo-yo intermittent recovery test (yo-yo) scores and their degree of association with a 20-m shuttle run (20MSR) and VO2max values.Methods:Subjects were elite (Australian Football League [AFL], n = 23), state-level (hockey, n = 15, and cricket, n = 27), and recreational team-sport players (n = 33). All performed a 20MSR and the yo-yo at either level 1 (recreational and state level) or level 2 (AFL). A recreational subgroup (n = 19) also performed a treadmill VO2max test.Results:Test–retest results found the yo-yo (levels 1 and 2) to be reliable (ICC = .86 to .95). The 20MSR and yo-yo level 1 scores correlated (P < .01) in the recreational (r = .81 to .83) and state-level groups (r = .84 to .86), and 20MSR and yo-yo level 2 scores, in the elite (r = .86) and recreational groups (r = .55 to .57). The VO2max and yo-yo level 1 scores in the recreational group correlated (P < .01, r = .87), but no association was found with yo-yo level 2 (r = .40 to .43, non significant).Conclusions:We conclude that level 1 (recreational and state level) and level 2 (elite) yo-yo scores were both strongly associated with 20MSR scores and VO2max (level 1: recreational subjects only). The yo-yo appears to measure aerobic fitness similarly to the 20MSR but may also be used as a field test of the ability to repeat high-intensity efforts.

Fuzzy Preference

Intuitionistic fuzzy preference relations (IFPRs) have the natural ability to reflect the positive, the negative and the non-determinative judgements of decision makers. A decision making model is proposed by considering the inherent property of IFPRs in this study, where the main novelty comes with the introduction of the concept of additive approximate consistency. First, the consistency definitions of IFPRs are reviewed and the underlying ideas are analyzed. Second, by considering the allocation of the non-determinacy degree of decision makers’ opinions, the novel concept of approximate consistency for IFPRs is proposed. Then the additive approximate consistency of IFPRs is defined and the properties are studied. Third, the priorities of alternatives are derived from IFPRs with additive approximate consistency by considering the effects of the permutations of alternatives and the allocation of the non-determinacy degree. The rankings of alternatives based on real, interval and intuitionistic fuzzy weights are investigated, respectively. Finally, some comparisons are reported by carrying out numerical examples to show the novelty and advantage of the proposed model. It is found that the proposed model can offer various decision schemes due to the allocation of the non-determinacy degree of IFPRs.

Decision making is one element of economic value, especially in the era of globalization, and if it is not acceptable in the decision making process, we will be left behind. According to Robins, (2003: 173), Salusu, (2000: 47), and Razik and Swanson, (1995: 476) say that decision making can be interpreted as a process of choosing a number of alternatives, how to act in accordance with concepts, or rules in solving problems to achieve individual or group goals that have been formulated using a number of specific techniques, approaches and methods and achieve optimal levels of acceptance.Decision making in organizations whether a decision is made for a person or group, the nature of the decision is often determined by rules, policies, prescribed, instructions that have been derived or practices that apply. To understand decision making within the organization it is useful to view decision making as part of the overall administrative process. In general, individuals tend to use simple strategies, even if in any complex matter, to get the desired solution, because the solution is limited by imperfect information, time and costs, limited thinking and psychological stress experienced by decision makers.
