A qualitative exploration of mentally tough behaviour in Australian football

The primary aim of this research was to generate insight into observable mentally tough behaviours, or MTb, across different contexts (e.g., training and competition) in an Australian football (AF) environment. A second aim of this research was to explore the utility of MTb as a distinct concept, and identify common behavioural qualities associated with MTb that separate it from other similar constructs. In total, 10 experienced full-time football operations staff were interviewed using a semi-structured interview guide, with inductive thematic analysis employed to analyse the data. Five main themes relating to MTb were identified: adaptive development, consistent training conduct, composed performance actions, responsible and accountable, and team supportive. Overall, the findings of the research provided preliminary support for the proposition that there exists a collection of MTb that are displayed more frequently by athletes considered to possess high levels of mental toughness compared to athletes who are perceived to have low levels of this psychological capacity. We propose a collection of necessary and sufficient behavioural qualities and a working definition of MTb to further our understanding of potential strategies to develop MT.

Preempting performance challenges: the effects of inoculation messaging on attacks to task self-efficacy

Although inoculation messages have been shown to be effective for inducing resistance to counter-attitudinal attacks, researchers have devoted relatively little attention toward studying the way in which inoculation theory principles might support challenges to psychological phenomena other than attitudes (e.g., self-efficacy). Prior to completing a physical (i.e., balance) task, undergraduates (N = 127, M_age = 19.20, SD = 2.16) were randomly assigned to receive either a control or inoculation message, and reported their confidence in their ability regarding the upcoming task. During the task, a confederate provided standardized negative feedback to all participants regarding their performance, and following the completion of the task, participants again reported their self-efficacy along with measures assessing in-task processes. Findings supported the viability of efficacy inoculation; controlling for pre-task self-efficacy, task performance, and relevant psycho-social variables (e.g., resilience, self-confidence robustness), participants in the inoculation condition reported greater confidence in their ability (i.e., task self-efficacy) than those in the control condition at post-task. Relative to those in the inoculation condition, participants in the control condition also experienced greater concentration disruption and self-presentation concerns during the task.

Syntheses of arnottin I and arnottin II

Short total syntheses of arnottin I and II were accomplished in 5 and 6 steps, respectively. A sesamol-benzyne cycloaddition with a 3-furyl-benzoate followed by regiospecific lactonization provided rapid, large-scale access to the core of arnottin I. Saponification of arnottin I and hypervalent iodide mediated spirocyclization provided an efficient and direct preparation of racemic arnottin II.

Promoting emergency medical care systems in the developing world: weighing the costs

Despite the global health community's historical focus on providing basic, cost-effective primary health care delivered at the community level, recent trends in the developing world show increasing demand for the implementation of emergency care infrastructures, such as prehospital care systems and emergency departments, as well as specialised training programmes. However, the question remains whether, in a setting of limited global health care resources, it is logical to divert these already-sparse resources into the development of emergency care frameworks. The existing literature overwhelmingly supports the idea that emergency care systems, both community-based and within medical institutions, improve important outcomes, including significant morbidity and mortality. Crucial to the success of any public health or policy intervention, emergency care systems also seem to be strongly desired at the community and governmental levels. Integrating emergency care into existing health care systems will ideally rely on modest, low-cost steps to augment current models of primary health care delivery, focusing on adapting the lessons learned in the developed world to the unique needs and local variability of the rest of the globe.

Characterization of 5-[5-(4-chlorophenyl-2-furanyl)]dihydro-2(3H)-furanone as a nonsteroidal antiinflammatory drug

5-[5-(4-Chlorophenyl-2-furanyl)]dihydro-2(3H)-furanone (F-1044), a nonsteroidal antiinflammatory drug related to orpanoxin, lacks the usual acid moiety of such agents. F-1044 had antiinflammatory activity equivalent to ibuprofen's and orpanoxin's in the carrageenin-induced paw edema model in normal and adrenalectomized rats. Antiinflammatory activity was also expressed in the guinea pig UV-induced erythema and rat established arthritis models. F-1044 was a more potent analgesic than ibuprofen and orpanoxin in the rat paw pressure assay. In contrast to the reference agents, F-1044 raised the pain threshold of both the yeast-injected and non-injected paws, suggesting a central component to its analgesic action. F-1044 was more potent than ibuprofen and orpanoxin in the rat brewer's yeast pyresis model. Based on its low activity in inhibiting bradykinin-induced bronchoconstriction in guinea pigs and low gastric irritation activity in rats. F-1044 appears to have a mechanisms of action that involves more than simple inhibition of prostaglandin synthesis. Thus F-1044 is a nonsteroidal antiinflammatory agent with unique chemical and pharmacological features.
