Linking self-efficacy and decision-making processes in developing soccer players

Objectives: In sports, adults with high self-efficacy have been shown to select their first option as the final choice more often in a dynamic decision-making test. Addressing the link between self-efficacy and decision making early in age could benefit the developmental potential of athletes. In this study, we examined the link between developing players’ decision self-efficacy and their decision-making processes comprising option generation and selection. Further, we explored the effect of time pressure on developing athletes’ decision making. Design: Developing athletes (N = 97) of two different age groups were asked to report their self-efficacy and to perform a dynamic decision-making task, in which time pressure was experimentally manipulated. Method: 48 younger (Mage = 8.76, SD = 1.15) and 49 older (Mage = 12.18, SD = 0.87) soccer players participated. Participants were randomly presented with video scenes of soccer match play. At the point of temporal occlusion, participants generated options about the next move. After generation, participants selected among the generated options their best option and indicated their decision and motor confidence. Results: The self-efficacy of developing players was neither related negatively to dynamic inconsistency nor positively to option or decision quality, but self-efficacy was positively related to motor confidence in the best option. Further, time pressure improved option and decision quality. Conclusion: Decision-making processes have been scrutinized by showing that developing players’ self-efficacy links to their motor skills rather than to their cognitive evaluation and by specifying the adaptation to time pressure. Thereby, results extend current theorizing on decision making

The effect of time constraint on anticipation, decision making, and option generation in complex and dynamic environments

Researchers interested in performance in complex and dynamic situations have focused on how individuals predict their opponent(s) potential courses of action (i.e., during assessment) and generate potential options about how to respond (i.e., during intervention). When generating predictive options, previous research supports the use of cognitive mechanisms that are consistent with long-term working memory (LTWM) theory (Ericsson and Kintsch in Phychol Rev 102(2):211–245, 1995; Ward et al. in J Cogn Eng Decis Mak 7:231–254, 2013). However, when generating options about how to respond, the extant research supports the use of the take-the-first (TTF) heuristic (Johnson and Raab in Organ Behav Hum Decis Process 91:215–229, 2003). While these models provide possible explanations about how options are generated in situ, often under time pressure, few researchers have tested the claims of these models experimentally by explicitly manipulating time pressure. The current research investigates the effect of time constraint on option-generation behavior during the assessment and intervention phases of decision making by employing a modified version of an established option-generation task in soccer. The results provide additional support for the use of LTWM mechanisms during assessment across both time conditions. During the intervention phase, option-generation behavior appeared consistent with TTF, but only in the non-time-constrained condition. Counter to our expectations, the implementation of time constraint resulted in a shift toward the use of LTWM-type mechanisms during the intervention phase. Modifications to the cognitive-process level descriptions of decision making during intervention are proposed, and implications for training during both phases of decision making are discussed

‘Talking a different language’: an exploration of the influence of organizational cultures and working practices on transition from child to adult mental health services

Background: Organizational culture is manifest in patterns of behaviour underpinned by beliefs, values, attitudes and assumptions, which can influence working practices. Cultural factors and working practices have been suggested to influence the transition of young people moving from child to adult mental health services. Failure to manage and integrate transitional care effectively can lead to young people losing contact with health and social care systems, resulting in adverse effects on health, well-being and potential. Methods: The study aim was to identify the organisational factors which facilitate or impede transition of young people from child and adolescent mental health services (CAMHS) to adult mental health services (AMHS) from the perspective of health professionals and representatives of voluntary organisations. Specific objectives were (i) to explore organizational cultures, structures, processes and resources which influence transition from child to adult mental health services; (ii) identify factors which constitute barriers and facilitators to transition and continuity of care and (iii) make recommendations for service improvements. Within an exploratory, qualitative design thirty four semi-structured interviews were conducted with health and social care professionals working in CAMHS and AMHS in four NHS Mental Health Trusts and four voluntary organizations, in England. Results: A cultural divide appears to exist between CAMHS and AMHS, characterized by different beliefs, attitudes, mutual misperceptions and a lack of understanding of different service structures. This is exacerbated by working practices relating to communication and information transfer which could impact negatively on transition, relational, informational and cross boundary continuity of care. There is also evidence of a cultural shift, with some positive approaches to collaborative working across services and agencies, involving joint posts, parallel working, shared clinics and joint meetings. Conclusions: Cultural factors embodied in mutual misperceptions, attitudes, beliefs exist between CAMHS and AMHS. Working practices can exert either positive or negative effects on transition and continuity of care. Implementation of shared education and training, standardised approaches to record keeping and information transfer, supported by compatible IT resources are recommended, alongside management strategies which evaluate the achievement of outcomes related to transition and continuity of care

Achieving continuity of care: facilitators and barriers in community mental health teams.

BACKGROUND: The integration of mental health and social services for people diagnosed with severe mental illness (SMI) has been a key aspect of attempts to reform mental health services in the UK and aims to minimise user and carer distress and confusion arising from service discontinuities. Community mental health teams (CMHTs) are a key component of UK policy for integrated service delivery, but implementing this policy has raised considerable organisational challenges. The aim of this study was to identify and explore facilitators and barriers perceived to influence continuity of care by health and social care professionals working in and closely associated with CMHTs. METHODS: This study employed a survey design utilising in-depth, semi-structured interviews with a proportionate, random sample of 113 health and social care professionals and representatives of voluntary organisations. Participants worked in two NHS Mental Health Trusts in greater London within eight adult CMHTs and their associated acute in-patient wards, six local general practices, and two voluntary organisations. RESULTS: Team leadership, decision making, and experiences of teamwork support were facilitators for cross boundary and team continuity; face-to-face communication between teams, managers, general practitioners, and the voluntary sector were facilitators for information continuity. Relational, personal, and longitudinal continuity were facilitated in some local areas by workforce stability. Barriers for cross boundary and team continuity were specific leadership styles and models of decision making, blurred professional role boundaries, generic working, and lack of training for role development. Barriers for relational, personal, and longitudinal continuity were created by inadequate staffing levels, high caseloads, and administrative duties that could limit time spent with users. Incompatibility of information technology systems hindered information continuity. Flexible continuity was challenged by the increasingly complex needs of service users. CONCLUSIONS: Substantive challenges exist in harnessing the benefits of integrated CMHT working to deliver continuity of care. Team support should be prioritised in terms of IT provision linked to a review of current models of administrative support. Investment in education and training for role development, leadership, workforce retention, and skills to meet service users' complex needs are recommended

The short-term effect of swimming training load on shoulder rotational range of motion, shoulder joint position sense and pectoralis minor length

Background: Shoulder pain or injury is the most common issue facing elite competitive swimmers and the most frequent reason for missed or modified training. Literature suggests that highly repetitive upper limb loading leads to inappropriate adaptations within the shoulder complex. The most likely maladaptations to occur are variations in shoulder rotational range of motion, reduction in joint position sense and shortened pectoralis minor length. This has yet to have been confirmed in experimental studies. The aim of this study was to investigate the short-term effects of swimming training load upon internal and external rotation range of motion, joint position sense and pectoralis minor length. Method: Sixteen elite swimmers training in the British Swimming World Class programme participated. Measures of internal and external range of motion, joint position sense error score and pectoralis minor length were taken before and after a typical 2h swimming session. Results: Following swimming training shoulder external rotation range of motion and pectoralis minor length reduced significantly (-3.4°,p=<0.001 and -0.7cm, p=<0.001, respectively), joint position sense error increased significantly (+2.0° error angle, p=<0.001). Internal rotation range of motion demonstrated no significant change (-0.6, p=0.53). Discussion: This study determined that elite level swimming training results in short-term maladaptive changes in shoulder performance that could potentially predispose them to injury

Local Chatter or International Buzz? Language Differences on Posts about Zika Research on Twitter and Facebook

Background When the Zika virus outbreak became a global health emergency in early 2016, the scientific community responded with an increased output of Zika-related research. This upsurge in research naturally made its way into academic journals along with editorials, news, and reports. However, it is not yet known how or whether these scholarly communications were distributed to the populations most affected by Zika. Methodology/Principal findings To understand how scientific outputs about Zika reached global and local audiences, we collected Tweets and Facebook posts that linked to Zika-related research in the first six months of 2016. Using a language detection algorithm, we found that up to 90% of Twitter and 76% of Facebook posts are in English. However, when none of the authors of the scholarly article are from English-speaking countries, posts on both social media are less likely to be in English. The effect is most pronounced on Facebook, where the likelihood of posting in English is between 11 and 16% lower when none of the authors are from English-speaking countries, as compared to when some or all are. Similarly, posts about papers written with a Brazilian author are 13% more likely to be in Portuguese on Facebook than when made on Twitter. Conclusions/Significance Our main conclusion is that scholarly communication on Twitter and Facebook of Zikarelated research is dominated by English, despite Brazil being the epicenter of the Zika epidemic. This result suggests that scholarly findings about the Zika virus are unlikely to be distributed directly to relevant populations through these popular online mediums. Nevertheless, there are differences between platforms. Compared to Twitter, scholarly communication on Facebook is more likely to be in the language of an author’s country. The Zika outbreak provides a useful case-study for understanding how scientific outputs are communicated to relevant populations. Our results suggest that Facebook is a more effective channel than Twitter, if communication is desired to be in the native language of the affected country. Further research should explore how local media—such as governmental websites, newspapers and magazines, as well as television and radio—disseminate scholarly publication

Recommendations for the transition of patients with ADHD from child to adult healthcare services:a consensus statement from the UK adult ADHD network

The aim of this consensus statement was to discuss transition of patients with ADHD from child to adult healthcare services, and formulate recommendations to facilitate successful transition. An expert workshop was convened in June 2012 by the UK Adult ADHD Network (UKAAN), attended by a multidisciplinary team of mental health professionals, allied professionals and patients. It was concluded that transitions must be planned through joint meetings involving referring/receiving services, patients and their families. Negotiation may be required to balance parental desire for continued involvement in their child’s care, and the child’s growing autonomy. Clear transition protocols can maintain standards of care, detailing relevant timeframes, responsibilities of agencies and preparing contingencies. Transition should be viewed as a process not an event, and should normally occur by the age of 18, however flexibility is required to accommodate individual needs. Transition is often poorly experienced, and adherence to clear recommendations is necessary to ensure effective transition and prevent drop-out from services

Clinical Pharmacokinetics and Dose Recommendations for Posaconazole in Infants and Children.

OBJECTIVES: The objectives of this study were to investigate the population pharmacokinetics of posaconazole in immunocompromised children, evaluate the influence of patient characteristics on posaconazole exposure and perform simulations to recommend optimal starting doses. METHODS: Posaconazole plasma concentrations from paediatric patients undergoing therapeutic drug monitoring were extracted from a tertiary paediatric hospital database. These were merged with covariates collected from electronic sources and case-note reviews. An allometrically scaled population-pharmacokinetic model was developed to investigate the effect of tablet and suspension relative bioavailability, nonlinear bioavailability of suspension, followed by a step-wise covariate model building exercise to identify other important sources of variability. RESULTS: A total of 338 posaconazole plasma concentrations samples were taken from 117 children aged 5 months to 18 years. A one-compartment model was used, with tablet apparent clearance standardised to a 70-kg individual of 15 L/h. Suspension was found to have decreasing bioavailability with increasing dose; the estimated suspension dose to yield half the tablet bioavailability was 99 mg/m2. Diarrhoea and proton pump inhibitors were also associated with reduced suspension bioavailability. CONCLUSIONS: In the largest population-pharmacokinetic study to date in children, we have found similar covariate effects to those seen in adults, but low bioavailability of suspension in patients with diarrhoea or those taking concurrent proton pump inhibitors, which may in particular limit the use of posaconazole in these patients

A Chirality-Based Quantum Leap

There is increasing interest in the study of chiral degrees of freedom occurring in matter and in electromagnetic fields. Opportunities in quantum sciences will likely exploit two main areas that are the focus of this Review: (1) recent observations of the chiral-induced spin selectivity (CISS) effect in chiral molecules and engineered nanomaterials and (2) rapidly evolving nanophotonic strategies designed to amplify chiral light-matter interactions. On the one hand, the CISS effect underpins the observation that charge transport through nanoscopic chiral structures favors a particular electronic spin orientation, resulting in large room-temperature spin polarizations. Observations of the CISS effect suggest opportunities for spin control and for the design and fabrication of room-temperature quantum devices from the bottom up, with atomic-scale precision and molecular modularity. On the other hand, chiral-optical effects that depend on both spin- and orbital-angular momentum of photons could offer key advantages in all-optical and quantum information technologies. In particular, amplification of these chiral light-matter interactions using rationally designed plasmonic and dielectric nanomaterials provide approaches to manipulate light intensity, polarization, and phase in confined nanoscale geometries. Any technology that relies on optimal charge transport, or optical control and readout, including quantum devices for logic, sensing, and storage, may benefit from chiral quantum properties. These properties can be theoretically and experimentally investigated from a quantum information perspective, which has not yet been fully developed. There are uncharted implications for the quantum sciences once chiral couplings can be engineered to control the storage, transduction, and manipulation of quantum information. This forward-looking Review provides a survey of the experimental and theoretical fundamentals of chiral-influenced quantum effects and presents a vision for their possible future roles in enabling room-temperature quantum technologies.ISSN:1936-0851ISSN:1936-086
