Identifying high-performing and promising athletes is an important task of national surf associations. However, the scientific foundation of performance indicators in surfing has only developed in recent years. This review aimed to (1) find out which performance characteristics discriminate between surfers of different skill levels, and (2) point out gaps in the existing literature and direct future studies by applying the Groningen Sport Talent Model (GSTM) to categorize findings. A systematic review of PubMed, Web of Science, MEDLINE and PsycInfo databases was performed according to the PRISMA guidelines. A total of thirty-one studies were included. Studies were found on anthropometric, physiological, technical, and tactical, but not on psychological characteristics of surfing performance. In total only six studies included female surfers. Findings suggest that a few performance indicators exist in relation to associations between physical capacities and surfing skill. For one, relative arm span seems to be beneficial to surfing performance and discriminates between differently skilled surfers. Additionally, 15 m and 400 m in-water paddle performance, as well as relative upper and lower-body strength also tend to be better in superior surfers. Technical skills, such as the ability to perform aerials and tube rides with a high completion rate, translate directly into an enhanced scoring potential and therefore success in surfing competitions. While a variety of characteristics for high-performance surfing are already indicated, future research needs to focus on developing reliable methods with higher ecological validity to assess these skills. Apart from the in-water paddle tests, most indicators lack a broadly accepted testing method. Especially, the field of psychological skills in surfing should be addressed more in the future.

AbstractObjectivesThis study aimed to assess the published literature on non-technical skills in otolaryngology surgery and examine the applicability of any research to others’ practice, and to explore how the published literature can identify areas for further development and guide future research.MethodsA systematic review was conducted using the following key words: ‘otolaryngology’, ‘otorhinolaryngology’, ‘ENT’, ‘ENT surgery’, ‘ear, nose and throat surgery’, ‘head and neck surgery’, ‘thyroid surgery’, ‘parathyroid surgery’, ‘otology’, ‘rhinology’, ‘laryngology’ ‘skull base surgery’, ‘airway surgery’, ‘non-technical skills’, ‘non technical skills for surgeons’, ‘NOTSS’, ‘behavioural markers’ and ‘behavioural assessment tool’.ResultsThree publications were included in the review – 1 randomised, controlled trial and 2 cohort studies – involving 78 participants. All were simulation-based studies involving training otolaryngology surgeons.ConclusionLittle research has been undertaken on non-technical skills in otolaryngology. Training surgeons’ non-technical skill levels are similar across every tested aspect. The research already performed can guide further studies, particularly amongst non-training otolaryngology surgeons and in both emergency and elective non-simulated environments.

High Performance Organization

Purpose This paper aims to synthesize existing knowledge on high performance organization (HPO) in terms of definitions, contemporary trends and findings from empirical studies; from which areas for future research can be proposed. Design/methodology/approach This systematic literature review applies the matrix method to analyze major HPO literature in peer-reviewed English articles. A total of 73 articles have been found in 59 journals. Findings There are three key findings that emerged from this study. First, the research on HPO has been burgeoned in the past decades, generating several compelling studies in different contexts. The trend of HPO research is now shifting from theory development to theory validation. Second, HPO has been defined in various ways in the extant literature. However, they all address the importance of aligning the firms’ resources with the market demand and integrating various types of performance to measure HPO relative to competitors for a prolonged period. Third, an assessment of empirical HPO studies revealed gaps in terms of the research context, research design and the HPO’s nomological network. Research limitations/implications The literature search in this review targeted at only articles published in the English language; therefore, publications in other languages were not included. Originality/value The strength of this study is that it provided an updated systematic review of HPO literature, is therefore, valuable in providing an overall picture of the current state of HPO research and providing potential directions for future studies.

Background: The effectiveness of traditional talent development (TD) programs can be questioned. Meanwhile, an extra pathway to the top has made its appearance: Talent transfer (TT). The aim of TT is to fast-track talented athletes into the high-performance environment. The first TT initiatives and studies exploring the TT process have been carried out. Objective: This systematic review gives an overview of studies examining TT, by situating TT within the developmental framework, comparing formal and informal TT and investigating the similarities between donor and transfer sports in TT from elite and non-elite level. Methods: A search was conducted on the PubMed and PsychINFO databases. The analysis was done according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta Analyses) statement. Results: After screening on title and abstract and full-text review, five studies remained for inclusion. Although literature is still scarce, results show that TT can serve as an alternative pathway in addition to the traditional TD programs. Literature suggests that similarities between donor and transfer sports are helpful, but this is not a prerequisite for TT. Besides, psychological factors are perceived to play an important role. Results regarding other determining factors of TT are still lacking. Athletes, national governing bodies and TD programs might benefit from this additional pathway, but the effectiveness of formal and informal TT remains unclear. Conclusion: A lot remains unknown about TT, hence future research is needed to increase our understanding of TT and its contribution as an extra pathway to the top.

Historically, the maintenance function of an organisation was viewed as a ‘necessary evil’; however, the view has shifted to seeing it as a strategic element within an organisation to accomplish its business objectives. For organisations to continue to be competitive, they need to harness the true potential of their people by evaluating ways for maintenance teams to achieve effective teamwork. In the light of this, the study was tailored to determine the factors that characterise high-performing maintenance teams in the petrochemical industry in South Africa. The study determined an importance ranking of these critical factors when implementing high-performance maintenance teams. A questionnaire was used to gather quantitative data from 69 respondents. Analysis of the data revealed that the most important factors for maintenance teams to achieve high performance were knowledge and motivation. It was also found that the most important performance indicators for maintenance were equipment availability, overall equipment effectiveness, and spares availability.

Purpose We conducted a systematic review of the literature regarding adult telepractice services (screening, assessment, and treatment) from approximately 2014 to 2019. Method Thirty-one relevant studies were identified from a literature search, assessed for quality, and reported. Results Included studies illustrated feasibility, efficacy, diagnostic accuracy, and noninferiority of various speech-language pathology services across adult populations, including chronic aphasia, Parkinson's disease, dysphagia, and primary progressive aphasia. Technical aspects of the equipment and software used to deliver services were discussed. Some general themes were noted as areas for future research. Conclusion Overall, results of the review continue to support the use of telepractice as an appropriate service delivery model in speech-language pathology for adults. Strong research designs, including experimental control, across multiple well-described settings are still needed to definitively determine effectiveness of telepractice services.

Now days there is a global consensus among all stakeholders that SMEs represent a driving force to the overall economic development, due to their significant contribution both on GDP and employment of national economies. SMEs also by numbers dominate the world business stage, although their contribution does vary among the countries. SMEs in Albania represents about 98% of the total enterprises with a contribution to national GDP for about 70%. The structure and the performance of national economy is depended very much on the economic performance and contribution of SME, that’s why most of the governments have strategic programmes which support the SME’s development. To measure SMEs’ performance and their ability to compete on national and international markets requires a lot of information in all aspects. Through this paper the author aims to measure and analyze the economic performance of SMEs operating in Albania. To achieve this objective, official data on business statistics published by national the statistical office (INSTAT) are used for two years period 2014-2015. In addition using an international framework addressed to the objective “improve the techniques for SMEs productivity measurement”, for the first time, a set of comparative performance indicators is established and in doing so, those results can be used as term of reference in future research activities in SMEs sector. From the results it came out that although the positive growth rate of GDP during the last years , the performance indicators of SMEs show a slightly negative trend, indicating indirectly the need for support, in order to empower their contribution in national economy.

Eligibility Criteria

We report the results of a systematic review and meta-analysis investigating the relationship between perceptual anchoring and dyslexia. Our goal was to assess the direction and degree of effect between perceptual anchoring and reading ability in typical and atypical (dyslexic) readers. We performed a literature search of experiments explicitly assessing perceptual anchoring and reading ability using PsycInfo (Ovid, 1860 to 2020), MEDLINE (Ovid, 1860 to 2019), EMBASE (Ovid, 1883 to 2019), and PubMed for all available years up to June (2020). Our eligibility criteria consisted of English-language articles and, at minimum, one experimental group identified as dyslexic - either by reading assessment at the time, or by previous diagnosis. We assessed for risk of bias using an adapted version of the Newcastle-Ottawa scale. Six studies were included in this review, but only five (n = 280 participants) were included in the meta-analysis (we were unable to access the necessary data for one study).The overall effect was negative, large and statistically significant; g = -0.87, 95% CI [-1.47, 0.27]: a negative effect size indicating less perceptual anchoring in dyslexic versus non-dyslexic groups. Visual assessment of funnel plot and Egger’s test suggest minimal bias but with significant heterogeneity; Q (4) = 9.70, PI (prediction interval) [-2.32, -0.58]. The primary limitation of the current review is the small number of included studies. We discuss methodological limitations, such as limited power, and how future research may redress these concerns. The variability of effect sizes appears consistent with the inherent variability within subtypes of dyslexia. This level of dispersion seems indicative of the how we define cut-off thresholds between typical reading and dyslexia populations, but also the methodological tools we use to investigate individual performance.

OBJECTIVEThere are currently no guidelines for the optimum age for surgical treatment of craniosynostosis. This systematic review summarizes and assesses evidence on whether there is an optimal age for surgery in terms of neurodevelopmental outcomes.METHODSThe databases MEDLINE, PsycINFO, CINAHL, Embase + Embase Classic, and Web of Science were searched between October and November 2016 and searches were repeated in July 2017. According to PICO (participants, intervention, comparison, outcome) criteria, studies were included that focused on: children diagnosed with nonsyndromic craniosynostosis, aged ≤ 5 years at time of surgery; corrective surgery for nonsyndromic craniosynostosis; comparison of age-at-surgery groups; and tests of cognitive and neurodevelopmental postoperative outcomes. Studies that did not compare age-at-surgery groups (e.g., those employing a correlational design alone) were excluded. Data were double-extracted by 2 authors using a modified version of the Cochrane data extraction form.RESULTSTen studies met the specified criteria; 5 found a beneficial effect of earlier surgery, and 5 did not. No study found a beneficial effect of later surgery. No study collected data on length of anesthetic exposure and only 1 study collected data on sociodemographic factors.CONCLUSIONSIt was difficult to draw firm conclusions from the results due to multiple confounding factors. There is some inconclusive evidence that earlier surgery is beneficial for patients with sagittal synostosis. The picture is even more mixed for other subtypes. There is no evidence that later surgery is beneficial. The authors recommend that future research use agreed-upon parameters for: age-at-surgery cut-offs, follow-up times, and outcome measures.

Abstract Background The knowledge about the experience of informal caregivers who provide care to people with moderate to advanced dementia in a domestic home setting is limited. A consequence of long hours of caregiving in addition to dealing with normal challenges of daily living is their experience of a poor quality of life. Some of their experiences may be described in terms of a feeling of powerlessness to make changes during care provision. This feeling may also suggest an experience of moral distress. The aim of this systematic review is to synthesise qualitative evidence relating to these experiences. Methods This review adopts a narrative synthesis approach. A search will be conducted for studies written in the English language in the bibliographic databases MEDLINE Complete, CINAHL, EMBASE, PsycINFO, Web of Science and Academic Search Complete covering periods from 1984 to present. Included studies will be qualitative or mixed-methods designs. The search terms will be related to dementia and caregivers, and the process will be focused on dementia at the moderate to the advanced stages within the domestic home setting. Reference lists of included papers will also be searched for additional relevant citations. Search terms and strategies will be checked by two independent reviewers. The identification of abstracts and full texts of studies will be done by the author, while the quality and the risk of bias will also be checked by the two independent reviewers. Discussion Psychological distress is cited as an experience reported within informal caregiving. For the caregiver, it is associated with a negative impact on general health. To date, no synthesis exists on the specific experience of informal caregiving for people with moderate to advanced dementia within the domestic home setting. This review considers that variation of accounts contributes to how the informal caregivers’ general experience is explored in future research. This may enable gaps in current knowledge to be highlighted within the wider context of caregiving in the domestic home setting. Systematic review registration This review is registered with PROSPERO (CRD42020183649).
