  • Description: The worldwide decline of wetland ecosystems calls for an urgent reassessment of their current status from a resilience perspective. Understanding the trajectories of changes that have produced the current situation is fundamental for assessing system resilience. Here, we examine long-term dynamics of wetland ecosystem change by reviewing paleoecological records from 11 representative lakes in China. We identify unprecedented change in alga communities in the context of last two centuries. Striking ecological shifts have occurred in all lakes, yet with spatial and temporal differences. The long-term trajectories of change in diatom species composition and structure indicate gradually eroded system resilience. These ecological shifts were shaped by socio-economic activities as China transformed from a rural agricultural to an industrialized society within the last several decades, during which multiple drivers have accumulated and acted synergistically. The balance between ecosystem and society, which appeared to exist for thousands of years, was broken by increasing population, new technology, and urbanization since the 1980s. The consequences are the emergence of new positive feedbacks with the potential to drive the coupled systems into undesirable states. By linking long-term social and ecological change at a regional scale, our study provides a novel contribution to the understanding of lake ecosystems resilience in present-day China. We argue that sustaining wetland ecosystems requires integrated approaches that incorporate a deeper understanding of social-ecological dynamics over decadal-centennial timescales to address the complex underlying mechanisms leading to the current degradation.

  • Description: Background: Team bat-or-stick sports, including cricket, softball and hockey, are popular among women. However, little is known about the injury profile in this population. Objective: The aim was to describe the incidence, nature and anatomical location of injuries in bat-or-stick sports played by women in a competitive league. Methods: This review was prospectively registered (PROSPERO CRD42015026715). CINAHL, MEDLINE, PsycINFO, PubMed, SPORTDiscus were systematically searched from January 2000 to September 2016, inclusive. Peer-reviewed original research articles reporting the incidence, nature and anatomical location of injuries sustained by women aged 18 + years in competitive bat-or-stick sports were included. Two meta-analyses based on injury incidence proportions (injury IP) and injury rates per 1000 person-days of athletic exposure (AE) were performed. Results: A total of 37 studies satisfied the inclusion criteria, and five had low risk of bias. The weighted injury IP was 0.42 [95% confidence interval (CI) 0.39–0.45]. The weighted injury rate was 6.12 (95% CI 6.05–6.18) overall, and greater in games [15.79 (95% CI 15.65–15.93)] than in practice [3.07 (95% CI 2.99–3.15)]. The ankle was the most commonly injured anatomical location, followed by the hand (including wrist and fingers), knee and head. Soft tissue and ligament injuries were most common types of injuries. Conclusion: Injury prevention in women’s sports is a novel and emerging field of research interest. This review highlights that injury incidence is high among female bat-or-stick players, but little information is known about direct causal mechanisms. This review clearly establishes the need for enhancements to injury data collection. Without this information, it will not be possible to develop evidence-based injury prevention interventions. © 2017, Springer International Publishing AG, part of Springer Nature.

  • Description: The aim of the present paper was to review the opportunities currently available to health service planners to advance sustainable development in their future-facing roles within health service organisation. Critical challenges and enablers to facilitate health services planners in adopting a pro-environmental lens are discussed. What is known about the topic? Despite its harmful effect on the environment, health has been slower than other industries to embrace the sustainable development agenda. The attitudes and knowledge base of health service planners with regard to environmental sustainability has not been widely studied. For health service planners, embracing pro-environmental considerations in sustainable model of care development is a powerful opportunity to review care paradigms and prepare for the implementation of meaningful, improved health and system efficiency. What does this paper add? This paper advances the case for health service planners to embrace a pro-environmental stance and guides health service leaders in the preparation and implementation of sustainable and improved health and system efficiency. What are the implications for practitioners? Health service planers are in an ideal position to champion the sustainable development agenda as they explore what care is delivered, how care is delivered and where care is delivered. External policy, health service leadership and carbon literacy are advanced as critical contextual factors to facilitate the key role that health service planners can play in building sustainable healthcare organisations.

  • Description: Objectives: Physiotherapists promote physical activity as part of their practice. This study reviewed the behaviour change techniques physiotherapists use when promoting physical activity in experimental and observational studies. Design: Systematic review of experimental and observational studies. Methods: Twelve databases were searched using terms related to physiotherapy and physical activity. We included experimental studies evaluating the efficacy of physiotherapist-led physical activity interventions delivered to adults in clinic-based private practice and outpatient settings to individuals with, or at risk of, non-communicable diseases. Observational studies reporting the techniques physiotherapists use when promoting physical activity were also included. The behaviour change techniques used in all studies were identified using the Behaviour Change Technique Taxonomy. The behaviour change techniques appearing in efficacious and inefficacious experimental interventions were compared using a narrative approach. Results: Twelve studies (nine experimental and three observational) were retained from the initial search yield of 4141. Risk of bias ranged from low to high. Physiotherapists used seven behaviour change techniques in the observational studies, compared to 30 behaviour change techniques in the experimental studies. Social support (unspecified) was the most frequently identified behaviour change technique across both settings. Efficacious experimental interventions used more behaviour change techniques (n = 29) and functioned in more ways (n = 6) than did inefficacious experimental interventions (behaviour change techniques = 10 and functions = 1). Conclusions: Physiotherapists use a small number of behaviour change techniques. Less behaviour change techniques were identified in observational studies compared to experimental studies, suggesting physiotherapists use less BCTs clinically than experimentally.

  • Description: Objectives: To evaluate the current evidence regarding the quantification of cricket fast-bowling skill. Methods: Studies that assessed fast-bowling skill (bowling speed and accuracy) were identified from searches in SPORTDiscus (EBSCO) in June 2017. The reference lists of identified papers were also examined for relevant investigations. Results: A total of 16 papers matched the inclusion criteria, and discrepancies in assessment procedures were evident. Differences in test environment, pitch, and cricket ball characteristics; the warm-up prior to test; test familiarization procedures; permitted run-up lengths; bowling spell length; delivery sequence; test instructions; collection of bowling speed data; and collection and reportage of bowling accuracy data were apparent throughout the literature. The reliability and sensitivity of fast-bowling skill measures have rarely been reported across the literature. Only 1 study has attempted to assess the construct validity of its skill measures. Conclusions: There are several discrepancies in how fast-bowling skill has been assessed and subsequently quantified in the literature to date. This is a problem, because comparisons between studies are often difficult. Therefore, a strong rationale exists for the creation of match-specific standardized fast-bowling assessments that offer greater ecological validity while maintaining acceptable reliability and sensitivity of the skill measures. If prospective research can act on the proposed recommendations from this review, then coaches will be able to make more informed decisions surrounding player selection, talent identification, return to skill following injury, and the efficacy of short- and long-term training interventions for fast bowlers.

  • Description: Background Functional foods are a fastest growing sector of the food industry. The development of functional foods comprising omega-3 fatty acids and probiotic bacteria, through complex coacervation process is an emerging area of research and product development. Scope and approach We reviewed relevant literature concerning the use of complex coacervation in microencapsulation, focusing primarily on the inclusion of probiotic bacteria and omega-3 oils into a single delivery format. This review covers advantages and disadvantages of the complex coacervation process to microencapsulate bioactive ingredients, viability of probiotic bacteria and oxidative stability of omega-3 oil during the complex coacervation process, the bioaccessibility of omega-3 oil and probiotic bacteria during simulated gastrointestinal conditions and in-vivo testings. Key findings and conclusions The review describes the advantages of co-encapsulation using complex coacervation followed by spray drying. It also describes the technological hurdles that need to be resolved for further development of industrial applications of co-encapsulation of probiotic bacteria and omega-3 lipids. The co-encapsulation concept has been widely used in pharmaceutical delivery systems, but is a relatively new concept in food ingredient stabilisation and delivery. There is a commercial need of co-encapsulation of multiple bioactive ingredients within a single microcapsules, due to decreased cost and enhanced product quality. Complex coacervation has been shown to be a useful method for the co-encapsulation of multiple unstable bioactive ingredients. Although in-vitro evaluation deliver useful bioavailability information, additional in-vivo and clinical trials are needed to determine the efficacy of bioactive release, particularly for microcapsules containing multiple bioactive ingredients. © 2017 Elsevier Ltd

  • Description: Purpose: This review sought to answer the question “What are the barriers and facilitators influencing people’s experience of return to work following spinal cord injury?” Methods: Studies that met the selection criteria were identified, presented and critically appraised using National Institute for Health and Care Excellence guidelines. Thematic synthesis was completed with studies possessing strong methodological rigor. Synthesis and interpretation involved three stages; coding of primary data; development of descriptive themes reflective of the primary data; and establishment of analytical themes to answer the review question. Results: Data from nine papers were included in the thematic synthesis. Several descriptive themes and three analytical themes were drawn from the data to answer the research question. Analytical themes included: a matrix of personal and environmental factors exists requiring complex navigation in order to create possibilities and opportunities for postinjury employment; the process of seeking or gaining employment shares a reciprocal relationship with the temporal nature of adjustment to spinal cord injury; and there is an intrinsic need for occupational engagement through paid employment. Conclusions: Returning to or gaining employment after spinal cord injury is a fundamentally difficult experience for people. Multiple strategies are required to support the navigation of the process. There is, however, a need in people with spinal cord injury, to be a worker, and with that comes the inherent benefits of being employed. Implications for rehabilitation Returning to work should be a significant focus of spinal cord injury rehabilitation. Employment is both possible and health promoting following spinal cord injury. Multiple strategies are required to support people to navigate the return to work process. It is important to be cognizant of the individual motivations for being a worker and the complexity of the adjustment process. Spinal cord injury centers can provide a consistent and supportive framework and culture of positivity about employment after spinal cord injury. © 2017 Informa UK Limited, trading as Taylor & Francis Group.

  • Description: The Pepsi Paradox refers to the observation that Pepsi is preferred to Coke in blind taste tests, despite Coke being regarded as the more successful brand. We begin by describing the origins of the Pepsi Paradox. We then outline a neural hypothesis for why it occurs. Next, we carefully assess the published behavioural studies related to the Pepsi Paradox, and on people's ability to distinguish colas by taste. We conclude that the existing research has failed to provide sufficient evidence for the existence of the Pepsi Paradox. In fact, there does not even seem to be a consistent taste preference for either beverage in the reviewed studies.

  • Description: Findings from efficacy studies have shown decreased in ACL injury rates in (predominantly female) athletes participating in prevention programs. Given the inherent higher ACL injury risk for females, the majority of intervention studies, have focused on female athletes. Subsequently, the content of exercises in ACL prevention programs is directed to target the modifiable ACL injury risk factors for female athletes. The literature is generally scarce regarding the efficacy of prevention programs to reduce ACL injuries in male athletes. In general, reduction of ACL injury rates seem to be limited to (young) female athletes and male athletes playing at low level of sports. Typically, ACL injury prevention programs entail a combination of plyometrics, strength training, agility and balance exercises. A problem is that improvements of movement patterns are not sustained over time. The reason may be related to the type of instructions given during training. Encouraging athletes to consciously control knee movements during exercises may not be optimal for the acquisition of complex motor skills. In the motor learning domain, these type of instructions are defined as an internal attentional focus. An internal focus, on one's own movements results in a more conscious type of control that may hamper motor learning. It has been established in numerous studies that an external focus of attention facilitates motor learning more effectively due to the utilization of automatic motor control. Subsequently, the athlete has more recourses available to anticipate on situations on the field and take appropriate feed forward directed actions. The purpose of this manuscript was to present methods to optimize motor skill acquisition of athletes and elaborate on athletes’ behavior.

  • Description: The etiology of running-related injury is important to consider as the effectiveness of a given running-related injury prevention intervention is dependent on whether etiologic factors are readily modifiable and consistent with a biologically plausible causal mechanism. Therefore, the purpose of the present article was to present an evidence-informed conceptual framework outlining the multifactorial nature of running-related injury etiology. In the framework, four mutually exclusive parts are presented: (a) Structure-specific capacity when entering a running session; (b) structure-specific cumulative load per running session; (c) reduction in the structure-specific capacity during a running session; and (d) exceeding the structure-specific capacity. The framework can then be used to inform the design of future running-related injury prevention studies, including the formation of research questions and hypotheses, as well as the monitoring of participation-related and non-participation-related exposures. In addition, future research applications should focus on addressing how changes in one or more exposures influence the risk of running-related injury. This necessitates the investigation of how different factors affect the structure-specific load and/or the load capacity, and the dose-response relationship between running participation and injury risk. Ultimately, this direction allows researchers to move beyond traditional risk factor identification to produce research findings that are not only reliably reported in terms of the observed cause-effect association, but also translatable in practice. © 2017 John Wiley & Sons A/S.

  • Description: Background Concussion is common in the sporting arena and is often challenging to diagnose. The development of wearable head impact measurement systems has enabled measurement of head kinematics in contact sports. Objectives The objective of this systematic review was to determine the characteristics of head kinematics measured by an accelerometer system among male athletes diagnosed with concussion. Methods A systematic search was conducted in July 2015. Inclusion criteria were English-language studies published after 1990 with a study population of male athletes, in any sport, where objectively measured biomechanical forces were reported in the setting of a concussive event. The random effects meta-analysis model was used to combine estimates of biomechanical force measurements in concussed athletes. Results Thirteen studies met the inclusion criteria, the majority of which were conducted with high school and college football teams in the US. Included studies measured a combination of linear and rotational acceleration. The meta-analysed mean peak linear head acceleration associated with a concussive episode was 98.68 g (95 % CI 82.36-115.00) and mean peak rotational head acceleration was 5776.60 rads/s 2 (95 % CI 4583.53-6969.67). The estimates of the biomechanical forces were consistent across studies, with I 2 values of 0 % for both metaanalyses. Conclusions Head impact monitoring through accelerometery has been shown to be useful with regard to characterising the kinematic load to the head associated with concussion. Future research with improved clinical outcome measures and head kinematic data may improve accuracy when evaluating concussion, and may assist with both interpretation of biomechanical data and the development and utilisation of implementation strategies for the technology.

  • Description: Telomeres are repetitive nucleoprotein structures at chromosome ends, and a decrease in the number of these repeats, known as a reduction in telomere length (TL), triggers cellular senescence and apoptosis. Heart disease, the worldwide leading cause of death, often results from the loss of cardiac cells, which could be explained by decreases in TL. Due to the cell-specific regulation of TL, this review focuses on studies that have measured telomeres in heart cells and critically assesses the relationship between cardiac TL and heart function. There are several lines of evidence that have identified rapid changes in cardiac TL during the onset and progression of heart disease as well as at critical stages of development. There are also many factors, such as the loss of telomeric proteins, oxidative stress, and hypoxia, that decrease cardiac TL and heart function. In contrast, antioxidants, calorie restriction, and exercise can prevent both cardiac telomere attrition and the progression of heart disease. TL in the heart is also indicative of proliferative potential and could facilitate the identification of cells suitable for cardiac rejuvenation. Although these findings highlight the involvement of TL in heart function, there are important questions regarding the validity of animal models, as well as several confounding factors, that need to be considered when interpreting results and planning future research. With these in mind, elucidating the telomeric mechanisms involved in heart development and the transition to disease holds promise to prevent cardiac dysfunction and potentiate regeneration after injury. © 2017 the American Physiological Society.

  • Description: Asia is experiencing an alarming rate of inland wetlands loss, posing a risk to the future long-term survival of many species depending on these ecosystems. This review on the status and conservation of the little curlew (Numenius minutus) aims to draw attention to the conservation challenges faced by migratory shorebird species using the inland wetlands of the East Asian-Australasian Flyway (EAAF). Extensive and systematic research survey efforts along the EAAF have focused on species using coastal and tidal areas rather than on species using inland wetlands. Knowledge gaps include functional ecology and physiological responses to quality of food resources, population trends, migratory strategy and the role species play in supporting ecosystems resilience. Studies using remote sensing and geographic information system techniques to track the movements of birds along the flyway and to map habitat condition will prove essential in the future to allow a better understanding of the dynamics occurring at the stopover areas, how birds use resources and what competition pressures exist among species. Ultimately, these studies will contribute to our ability to predict changes and establish management practices for the long-term protection and conservation of the stopover areas for a suite of shorebird species using inland wetlands along the flyway. © CSIRO 2017.

  • Description: A meta-analysis of up to 20 datasets is reported that examined the relationships between Cloninger's personality dimensions and Attention Deficit Hyperactivity Disorder (ADHD). Cloninger's model comprises four temperament (Novelty-Seeking, Harm-Avoidance, Reward Dependence, and Persistence) and three character (Self-Directedness, Cooperation, and Self-Transcendence) dimensions. Major findings were that all personality dimensions, except Self-Transcendence, were significantly associated with ADHD. These associations had different directions and magnitudes of relationship with ADHD. The associations were especially strong for Novelty-Seeking and Self-Directedness, being positive for Novelty-Seeking and negative for Self-Directedness. In addition, the association between ADHD and Persistence was moderated by age (stronger in children than adults) and source (stronger in clinical samples than community samples). Further, the association between harm avoidance and ADHD was moderated by age (strong and significant in adults, but not significant in children). Findings are discussed in relation to past work and the different strengths of the associations found between Cloninger's personality dimensions and ADHD, developmental differences in these relationships, implications for theoretical models of ADHD, the influence of biological and environmental factors in the expression of ADHD, implications for treatment and diagnosis, and the underlying processes for the relationships between personality and ADHD. © 2016 Elsevier Ltd

  • Description: Australia's Gippsland Basin contains a semi-continuous Eocene-Oligocene (41.5–28.4 Ma) near-coastal coal record that formed adjacent to Pacific Ocean. Traralgon and Morwell Formation brown coals include 4 main seams (T2, T1, T0, M2). Coal seam palynology records show late Middle Eocene (T2) coals formed under megathermic conditions characterized by high-gymnosperm contents, Late Eocene (T1) coals formed under mesothermic conditions characterized by reduced-gymnosperm contents and earliest indications of palaeoclimate cooling. Earliest Oligocene T0 coal record (33.9–31.5 Ma) contains high-gymnosperm palynology profile, very similar to the T2 coals. The earliest indication of cooler climes only begins after this coal formed as indicated by low-gymnosperm high-Nothofagus (southern beech) pollen proportions. We suggest in Gippsland the earliest evidence for major glacial cooling (by inference the Oi1 event) be placed immediately above the T0 coal seam where Early to Late Oligocene Morwell Formation sands, clays and coals contain low counts of gymnosperms (< 10%) but high average proportions of Nothofagus (50%). This is the main definitive indicator that palaeoclimates had cooled between the Eocene and Oligocene. This agrees with the current ocean drilling position of the earliest (Oi1) glacial event shortly above the Eocene-Oligocene boundary. A number of contemporaneous Middle to Late Eocene brown coals occurred in near-coastal settings across 1200 km of southern Australia. Palaeogeographically, all these coal basins faced the Australo-Antarctic Gulf and have a much lower gymnosperm proportion (< 10%), low Nothofagus proportion (< 10%), but very high (non-Nothofagus) angiosperms proportion. This suggests a different climatic regime separated a cooler and wetter Gippsland Basin flora that responded to the cooler Proto-Ross Sea Gyre rotating around a wide Pacific Ocean, and a warm-wet climate associated with a warm proto-Leeuwin current of the Australo-Antarctic Gulf. © 2017 Elsevier B.V.

  • Description: Objective To identify elements of endorsed definitions of equity in healthcare and classify domains of these definitions so that policy makers, managers, clinicians, and politicians can form an operational definition of equity that reflects the values and preferences of the society they serve. Design Systematic review where verbatim text describing explicit and implicit definitions of equity were extracted and subjected to a thematic analysis. Data sources The full holdings of the AMED, CINAHL plus, OVID Medline, Scopus, PsychInfo and ProQuest (ProQuest Health & Medical Complete, ProQuest Nursing and Allied Health Source, ProQuest Social Science Journals) were individually searched in April 2015. Eligibility criteria for selecting studies Studies were included if they provided an original, explicit or implicit definition of equity in regards to healthcare resource allocation decision making. Papers that only cited earlier definitions of equity and provided no new information or extensions to this definition were excluded. Results The search strategy yielded 74 papers appropriate for this review; 60 of these provided an explicit definition of equity, with a further 14 papers discussing implicit elements of equity that the authors endorsed in regards to healthcare resource allocation decision making. Five key themes emerged i) Equalisation across the health service supply/access/outcome chain, ii) Need or potential to benefit, iii) Groupings of equalisation, iv) Caveats to equalisation, and v) Close enough is good enough. Conclusions There is great inconsistency in definitions of equity endorsed by different authors. Operational definitions of equity need to be more explicit in addressing these five thematic areas before they can be directly applied to healthcare resource allocation decisions. © 2016 Elsevier Ltd

  • Description: Spectrum frequency is a valuable resource for wireless communication but very limited in its availability. Due to the extensive use and ever increasing demand of spectrum bands by wireless devices and newer applications, unlicensed band is becoming congested, while licensed bands are found mostly underutilized. To solve this problem of spectrum scarcity, cognitive radio (CR) devices can share licensed bands opportunistically in several ways. We analyze the three main dynamic sharing models (commons, shared-use, and exclusive-use) proposed in literature with extensive analysis of the exclusive-use model, which is the most promising as it provides benefits to both licensed and unlicensed users. In this model, CR-enabled service providers, also known as secondary service providers, can buy or lease spectrum from licensed, known as primary service providers, for both short and long duration and gain exclusive rights to access the spectrum. In this survey paper, exclusive-use trading approaches, namely, game theory, market equilibrium, and classical, hybrid and other models are reviewed extensively and their characteristics and differences are highlighted and compared. We also propose possible future research directions on exclusive-use CR model. © 1998-2012 IEEE.

  • Description: Background: Groin injury is a common musculoskeletal complaint for athletes competing in a variety of sports. The extent to which exercise interventions incorporating external load are an appropriate option for the treatment and prevention of groin injury in athletes is not yet clear. Objectives: The aim of this review was to describe and evaluate exercise therapy interventions and outcomes for the treatment and prevention of groin injury with specific attention to application of external load. Data Sources: The databases Medline, PubMed, SPORTDiscus, Web of Science, and Cochrane were searched on 18 April 2016. Study Eligibility Criteria: This review was registered as PROSPERO CRD42016037752 and a systematic search was conducted with the following inclusion criteria: any study design evaluating exercise interventions for the prevention or treatment of groin pain in athletes. Data Analysis: Two independent authors screened search results, performed data extraction, assessed risk of bias using the modified Downs and Black appraisal tool and determined strength and level of evidence. Reporting standards for exercise interventions were assessed using the Consensus for Exercise Reporting Template (CERT). Results: A total of 1320 titles were identified with 14 studies satisfying the inclusion criteria, four (29%) of which demonstrated low risk of bias. Ten (71%) studies utilised external load as a component of the exercise intervention. Reporting standards for exercise intervention scores ranged from 0 to 63%. Conclusion: There is limited evidence from level 2 and 3 studies indicating exercise therapy may reduce the incidence and hazard risk of sustaining a groin injury in athletes. There is strong evidence from level 4 studies indicating exercise therapy is beneficial as a treatment for groin injury in athletes in terms of symptom remission, return to sport and recurrence outcomes. However, there are limited studies with low risk of bias, and exercise interventions for the treatment of groin injury are poorly described. © 2017, Springer International Publishing Switzerland.
