    In recent years, scholars have contested conventional narratives such as that the League of Nations was a complete ‘failure’ or that the United Nations was a novelty in comparison with the League. Scholars now offer more nuanced and archive-based analyses. However, while traditional research has...... emphasised the establishment of the first formally independent international civil service and the corresponding secretariat as one of the League's few big achievements, the subject has not substantially benefitted from these new historical studies. This article helps to shed some light on the secretariat......'s nature and how international the staff really was. After examining the prevailing image of the international civil service at the League, the data will be supplemented by an analysis of the archive material with regard to recruitment and selected personnel files. This article argues that the secretariat...

    2014-09-01

    The International League Against Epilepsy (ILAE) Classification of Seizures in 1981 and the Classification of the Epilepsies, in 1989 have been widely accepted the world over for the last 3 decades. Since then, there has been an explosive growth in imaging, genetics and other fields in the epilepsies which have changed many of our concepts. It was felt that a revision was in order and hence the ILAE commissioned a group of experts who submitted the initial draft of this revised classification in 2010. This review focuses on what are the strengths and weaknesses of this new proposed classification, especially in the context of a developing country.

  7. Notes on the origins of Epilepsia and the International League Against Epilepsy.

    2009-03-01

    The recent discovery of archival material has shed interesting light on the origins of Epilepsia and also the International League Against Epilepsy (ILAE). The idea of an international journal devoted to epilepsy seems first to have arisen from talks between Dr. L. J. J. Muskens and Dr. W. Aldren Turner in 1905. A protracted series of subsequent letters between Muskens and a Haarlem publisher show how the idea slowly took shape. The committee of patronage, editorial board, and editorial assistants was probably first approached at the First International Congress of Psychiatry, Neurology, Psychology, and Nursing of the Insane, held in Amsterdam in 1907. At this meeting, the concept of an international organization to fight epilepsy (to become the ILAE) was also first proposed in public, again by Muskens. The concept of the ILAE was clearly modeled on another international organization-the International Commission for the Study of the Causes of Mental Diseases and Their Prophylaxis. This Commission had been first publicly proposed in 1906 by Ludwig Frank, at the Second International Congress for the Care and Treatment of the Insane. The proposed Commission and ILAE shared many features, aims, and personnel. Despite an auspicious start, the International Commission was prevented by personal and political differences from ever actually coming into being. However, the first issue of Epilepsia appeared in March 1909 and the ILAE was inaugurated in August 1909; and both have flourished and celebrate their centenaries this year.

    Dempsey, GM, Gibson, NV, Sykes, D, Pryjmachuk, BC, and Turner, AP. Match demands of senior and junior players during International Rugby League. J Strength Cond Res 32(6): 1678-1684, 2018-This study aims to quantify and compare the positional game demands of international junior and senior rugby league competition for the first time. Global positioning system (GPS) and video analysis were used to track 118 elite male rugby league players (57 seniors aged 28.7 ± 4.4 years; 61 juniors aged 17.2 ± 0.5 years) over 10 international matches (6 senior; 4 junior) characterized as either forwards (n = 67) or backs (n = 51). There were significant increases in the offensive carries (0.18 cf. 0.09 n·min; r = 0.56) and defensive tackles (0.36 cf. 0.23 n·min; r = 0.3) between senior and junior players, and forwards and backs (0.16 cf. 0.09; r = 0.34 and 0.41 cf. 0.14; r = 0.52), respectively. Running demands were significantly greater in backs than forwards (independent of playing level) for total distance (6,962 ± 1,263 m cf. 4,879 ± 1,824 m; r = 0.55), individualized high-speed distances (310 ± 158 m cf. 250 ± 171 m; r = 0.2), high-intensity accelerations (28.7 ± 12.1 m·s cf. 21.9 ± 11.7 m·s; r = 0.27), and decelerations (57.2 ± 18.3 m·s cf. 43.0 ± 17.8 m·s; r = 0.38). Positional differences were eliminated when reported relative to minutes played. From a practical perspective, although running demands relative to time on the pitch may prepare junior players for senior competition, it is not representative of the increased body mass and contact frequency within the senior game. Coaches should therefore reflect these differences within their physical preparation programs to prepare junior athletes accordingly for progression to the senior level.

    To establish applicability, the recently proposed International League Against Epilepsy (ILAE) consensus on drug-resistant epilepsy (DRE) requires testing in clinical and research settings. This study evaluates the reliability and validity of these criteria in a clinical population. In phase I, two independent evaluators reviewed 97 randomly selected medical records of patients with epilepsy at two separate intervals. Both ILEA consensus and standard diagnostic criteria were employed. Kappa, weighted kappa, and intraclass correlation coefficient (ICC) were used to determine interobserver and intraobserver variability. In phase II, ILAE consensus criteria were applied to 250 patients with epilepsy to determine risk factors associated with development of DRE and to calculate point prevalence. The interobserver agreement of the four definitions was as follows: Berg (0.56), Kwan and Brodie (0.58), Camfield and Camfield (0.69), and ILAE (0.77). The intraobserver agreement of the four definition was as follows: Berg (0.81), Kwan and Brodie (0.82), Camfield and Camfield (0.72), and ILAE (0.82). The prevalence of DRE was the following: with the Berg's definition was 28.4%, Kwan and Brodie 34%, Camfield and Camfield 37%, and with ILAE was 33%. This is first study to establish reliability and validity of ILAE criteria for the diagnosis of DRE. This new definition compares favorably with previously established constructs, which continue to retain clinical significance. Wiley Periodicals, Inc. © 2014 International League Against Epilepsy.

  11. The early history (1909-1961) of Epilepsia, the journal of the International League Against Epilepsy, and its echoes today.

    2007-01-01

    This paper records the history of Epilepsia, the journal of the International League Against Epilepsy, from its inception in 1908/1909 until the beginning of its fourth series in 1961. During this time, publication was interrupted on three occasions and so the journal appeared in four series, with a complex numbering system. Over the years, the content and format of the journal has varied. Its role has changed over the years, at times primarily as a scientific organ and at other times as a source of ILAE news and reports. Concerns throughout its history have included its role as an historical record, its international representation, financial vicissitude, quality of papers, the balance between basic and clinical science, the value of clinical papers, and issues of overspecialization. Epilepsia is today the leading clinical epilepsy journal; but these are still significant concerns, and a knowledge of the history of Epilepsia is important for understanding the current position of the journal.

    Full Text Available Alimentación y manejo del calostro en el ganado de leche. El presente trabajo es una revisión de literatura cuyo objetivo es resaltar la importancia de la alimentación y manejo del calostro en el ganado de leche. La transferencia de inmunidad pasiva en terneras debe ocurrir por ingestión de calostro, ya que la placenta bovina previene la transferencia de inmunoglobulinas (Ig de la madre al feto. La concentración de Ig en el calostro ha sido asociada como un factor importante para alcanzar niveles adecuados de inmunoglobulinas en el suero sanguíneo de terneras recién nacidas. Sin embargo, las terneras pueden absorber Ig del calostro solamente por un tiempo limitado después del nacimiento, y poca absorción es posible más allá de 24 h. Una inadecuada absorción de Ig, especialmente IgG1 dará como resultado bajas concentraciones de Ig en el suero de las terneras y un mayor riesgo de adquirir enfermedades que eventualmente podrían ocasionar la muerte. Además del tiempo que transcurre entre el nacimiento y el suministro de calostro, la concentración de Ig en el suero sanguíneo de las terneras dependerá de la masa de Ig consumidas, lo cuál está en función del volumen de calostro consumido, la concentración de Ig en el mismo y la efi ciencia de absorción de las Ig por parte de la ternera. Muchos factores infl uyen sobre la concentración del Ig en el calostro de vacas lecheras, entre ellos el número de lactancia, la cantidad de calostro producido y el tiempo transcurrido después del parto.

    The purpose of this study was to compare movement pattern, fatigue development, and heart rate (HR) for top-class elite female players when playing international (INT) vs. domestic league games (DOM). Video-based time-motion analyses and HR recordings were performed on 17 players during INT and DOM. The distances covered in high-intensity running (HIR) and sprinting were longer (p game types, the amount of HIR was reduced by 24-27% (p game. The midfielders covered longer (p game and in the most intense 5-minute period of the games, whereas no differences were observed between the game types for defenders. No difference in the HR response was found between INT and DOM. In conclusion, more HIR and sprinting occur in international compared with domestic games, which may affect the fatigue development for players in physically demanding roles. Thus, our results are important to coaches to prepare players to meet the challenges of international soccer games and show that the ability to perform intense intermittent exercise should be trained regularly in elite female players.

    The International Society of Hypertension and the World Hypertension League have developed a policy statement calling for reducing dietary salt. The policy supports the WHO and the United Nations recommendations, which are based on a comprehensive and up-to-date review of relevant research. The policy statement calls for broad societal action to reduce dietary salt, thus reducing blood pressure and preventing hypertension and its related burden of cardiovascular disease. The hypertension organizations and experts need to become more engaged in the efforts to prevent hypertension and to advocate strongly to have dietary salt reduction policies implemented. The statement is being circulated to national hypertension organizations and to international nongovernmental health organizations for consideration of endorsement. Member organizations of the International Society of Hypertension and the World Hypertension League are urged to support this effort.

    Despite the increasing use of dietary therapies for children and adults with refractory epilepsy, the availability of these treatments in developing countries with limited resources remains suboptimal. One possible contributory factor may be the costs. There is often reported a significant perceived need for a large ketogenic diet team, supplements, laboratory studies, and follow-up visits to provide this treatment. The 2009 Epilepsia Consensus Statement described ideal requirements for a ketogenic diet center, but in some situations this is not feasible. As a result, the International League Against Epilepsy (ILAE) Task Force on Dietary Therapy was asked to convene and provide practical, cost-effective recommendations for new ketogenic diet centers in resource-limited regions of the world.

    Given the significant impact that psychosocial factors and epilepsy treatments can have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is great clinical interest in the role of psychological evaluation and treatments to improve HRQOL and comorbidities. Therefore, the International League Against Epilepsy (ILAE) charged the Psychology Task Force with the development of recommendations for clinical care based on evaluation of the evidence from their recent Cochrane review of psychological treatments in individuals with epilepsy. The literature search for a recent Cochrane review of randomized controlled trials investigating psychological treatments for individuals with epilepsy constitutes the key source of evidence for this article. To provide practical guidance to service providers, we provide ratings on study research designs based on (1) the American Academy of Neurology's Level of Evidence system and (2) the Grading of Recommendations, Assessment, Development, and Evaluation system. This paper is the culmination of an international collaboration process involving pediatric and adult psychologists, neurologists, psychiatrists, and neuropsychiatrists. The process and conclusions were reviewed and approved by the ILAE Executive Committee. The strongest evidence for psychological interventions was identified for the most common mental health problems, including depression, neurocognitive disturbances, and medication adherence. Psychological interventions targeting the enhancement of HRQOL and adherence and a decrease in comorbidity symptoms (anxiety, depression) should be incorporated into comprehensive epilepsy care. There is a range of psychological strategies (ie, cognitive behavioral therapy and mindfulness-based therapies) that show promise for improving the lives of persons with epilepsy, and clinical recommendations are provided to assist epilepsy health care providers in treating the comorbidities and

    The main activities in international biological standardization during the 18 years that followed the first international biological standardization meeting in London in 1921 were concerned with expressing the potencies of test preparations in comparison with reference materials. After the Second World War, however, it became clear that the testing of biological substances against international reference materials was only one among several measures for obtaining safe and potent products. The activities in international biological standardization were therefore widened so that, by the strict observance of specific manufacturing and control requirements, it was possible to gain further in safety and efficacy. At the end of 1987, 42 international requirements for biological substances were available and were being used as national requirements, sometimes after minor modification, by the majority of WHO's Member States. This is of utmost importance for the worldwide use of safe and potent biological products, including vaccines.

    Since previous reviews of epidemiologic studies of premature mortality among people with epilepsy were completed several years ago, a large body of new evidence about this subject has been published. We aim to update prior reviews of mortality in epilepsy and to reevaluate and quantify the risks, potential risk factors, and causes of these deaths. We systematically searched the Medline and Embase databases to identify published reports describing mortality risks in cohorts and populations of people with epilepsy. We reviewed relevant reports and applied criteria to identify those studies likely to accurately quantify these risks in representative populations. From these we extracted and summarized the reported data. All population-based studies reported an increased risk of premature mortality among people with epilepsy compared to general populations. Standard mortality ratios are especially high among people with epilepsy aged <50 years, among those whose epilepsy is categorized as structural/metabolic, those whose seizures do not fully remit under treatment, and those with convulsive seizures. Among deaths directly attributable to epilepsy or seizures, important immediate causes include sudden unexpected death in epilepsy (SUDEP), status epilepticus, unintentional injuries, and suicide. Epilepsy-associated premature mortality imposes a significant public health burden, and many of the specific causes of death are potentially preventable. These require increased attention from healthcare providers, researchers, and public health professionals. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    2013-01-01

    In its 2010 report, the International League Against Epilepsy Commission on Classification and Terminology had made a number of changes to the organization, terminology, and classification of seizures and epilepsies. This study aims to test the usefulness of this revised classification scheme on children with epilepsies aged between 0 and 18 years old. Of 527 patients, 75.1% only had 1 type of seizure and the commonest was focal seizure (61.9%). A specific electroclinical syndrome diagnosis could be made in 27.5%. Only 2.1% had a distinctive constellation. In this cohort, 46.9% had an underlying structural, metabolic, or genetic etiology. Among the important causes were pre-/perinatal insults, malformation of cortical development, intracranial infections, and neurocutaneous syndromes. However, 23.5% of the patients in our cohort were classified as having "epilepsies of unknown cause." The revised classification scheme is generally useful for pediatric patients. To make it more inclusive and clinically meaningful, some local customizations are required.

    Many studies have explored closed kinetic chain (CKC) shoulder exercises (SEs) with a sling because they are safer and more effective than open-chain exercises, especially in early stages of treatment. However, the application of CKC SE in youth baseball players has rarely been attempted, although teenage baseball players also experience shoulder pain. To investigate the effects of CKC SE on the peak torque of shoulder internal rotation (IR) and external rotation (ER) in youth baseball players. Single-group pretest, posttest. Biomechanics laboratory. 23 Little League Baseball players with subacromial impingement syndrome. The CKC SE with a sling was CKC shoulder-flexion exercise, extension exercise, IR exercise, and ER exercise. This exercise regimen was conducted 2 or 3 times/wk for 8 wk. The peak torque of shoulder IR and ER was measured using an isokinetic dynamometer. Concentric shoulder rotation was performed, with 5 repetitions at an angular velocity of 60°/s and 15 at 180°/s. The IR and ER peak torque significantly increased at each angular velocity after the exercise program. In particular, the increase in IR and ER peak torque values was statistically significant at an angular velocity of 180°/s. CKC SE was effective in increasing shoulder IR and ER strength, demonstrating its potential benefits in the prevention and treatment of shoulder injury. In addition, increased IR peak torque appears to improve throwing velocity in baseball players.

    Full Text Available Creemos oportuno ilustrar al público, aunque sea en forma somera, sobre lo que es la pasteurización de la leche, ya que esta es una de las mayores necesidades de Bogotá. En la capital de la república no se consume hoy leche en cantidad suficiente, debido a la falta de conocimientos del público en relación con el alto valor alimenticio de ésta, y de sus propiedades como base de la alimentación diaria. Y es indudable que el cuerpo médico se guarda indicar su uso abundante, como pasa en todos los países adelantados del mundo, por los peligros que of.recen las leches crudas que en la sabana se producen, y por lo malo de la calidad de la leche cuando se hierve.

    Dulce de leche samples available in the Brazilian market were submitted to sensory profiling by quantitative descriptive analysis and acceptance test, as well sensory evaluation using the just-about-right scale and purchase intent. External preference mapping and the ideal sensory characteristics of dulce de leche were determined. The results were also evaluated by principal component analysis, hierarchical cluster analysis, partial least squares regression, artificial neural networks, and logistic regression. Overall, significant product acceptance was related to intermediate scores of the sensory attributes in the descriptive test, and this trend was observed even after consumer segmentation. The results obtained by sensometric techniques showed that optimizing an ideal dulce de leche from the sensory standpoint is a multidimensional process, with necessary adjustments on the appearance, aroma, taste, and texture attributes of the product for better consumer acceptance and purchase. The optimum dulce de leche was characterized by high scores for the attributes sweet taste, caramel taste, brightness, color, and caramel aroma in accordance with the preference mapping findings. In industrial terms, this means changing the parameters used in the thermal treatment and quantitative changes in the ingredients used in formulations.

    Gordan Struić

    2017-12-01

    Full Text Available Although the idea of collective security has long existed in the history of international relations, the League of Nations was the first modern international organisation based on the idea of collective security at the global level. In this context, the author aims at giving a systematic review of collective security and its mechanisms comprised in the Covenant of the League of Nations. To this end, after introductory considerations and a short review of the conceptual definition, postulates, roots, and critiques of collective security, the paper discusses its mechanisms in the Covenant of the League of Nations in order to examine, firstly, which provisions encompassed these mechanisms and what they were composed of and secondly, why these mechanisms failed to achieve their purpose. For this reason, the conclusions in this paper rely on a normative analysis of the Covenant of the League of Nations, as well as on the specific examples from the history of international relations during the period considered.

    Un bajo porcentaje cumplió con todas las normas del Ministerio de Salud y se trata de Plantas que reciben y procesan leches de hatos, en donde las instalaciones, la alimentación, la sanidad, la calidad genética y la producción
    están a la altura de los países industrializados.

    II. El consumo de leche en el país es bajo y no alcanza los niveles recomendados por los organismos de Salud.

    III. La leche es susceptible de contaminarse por la ignorancia, negligencia, prácticas fraudulentas o el empleo de técnicas inadecuadas en su procesamiento, transporte, conservación, comercialización e industrialización.

    IV. Se plantean interrogantes sobre la presencia en la leche, de residuos de antibióticos, pesticidas, hormonas, tranquilizantes, compuestos inorgánicos y la forma como puedan estar afectando la salud humana.

    V. La contaminación cada vez mayor del ambiente, el rápido transporte de los alimentos; sus técnicas de elaboración, los cambios en los hábitos alimentarios, han aumentado los peligros de enfermedades que se pueden trasmitir por los alimentos.

    VI. La Salud depende en buena parte de la alimentación y si los alimentos de origen animal son medios de propagación de agentes patógenos y tóxicos, la respuesta a este interrogante no es solamente cómo aumentar la producción, sino cómo alimentar una población afectada por pobreza y desnutrición con alimentos sanos.

    Actinic keratosis (AK) is a frequent health condition attributable to chronic exposure to ultraviolet radiation. Several treatment options are available and evidence based guidelines are missing. The goal of these evidence- and consensus-based guidelines was the development of treatment recommendations appropriate for different subgroups of patients presenting with AK. A secondary aim of these guidelines was the implementation of knowledge relating to the clinical background of AK, including consensus-based recommendations for the histopathological definition, diagnosis and the assessment of patients. The guidelines development followed a pre-defined and structured process. For the underlying systematic literature review of interventions for AK, the methodology suggested by the Cochrane Handbook for Systematic Reviews of Interventions, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was adapted. All recommendations were consented during a consensus conference using a formal consensus methodology. Strength of recommendations was expressed based on the GRADE approach. If expert opinion without external evidence was incorporated into the reasoning for making a certain recommendation, the rationale was provided. The Guidelines underwent open public review and approval by the commissioning societies. Various interventions for the treatment of AK have been assessed for their efficacy. The consenting procedure led to a treatment algorithm as shown in the guidelines document. Based on expert consensus, the present guidelines present recommendations on the classification of patients, diagnosis and histopathological definition of AK. Details on the methods and results of the systematic literature review and guideline development process have been published separately. International guidelines are intended to be adapted to national or regional

    The development of the Internet and subsequent evolution of social networking has significantly changed the effectiveness of patient advocacy groups for rare diseases. The greatest degree of change has occurred at the patient level, with an increased ability of affected individuals to share experiences and support, and to raise public awareness. Other changes have occurred, not only in the way rare diseases are diagnosed, studied, and treated, but also in how they are addressed at the level of legislation and public policy. The International Dravet syndrome Epilepsy Action League (IDEA League) is the leading patient advocacy organization for Dravet syndrome and related genetic ion-channel epilepsy disorders (hereafter referred to as Dravet syndrome or severe myoclonic epilepsy of infancy, SMEI). The IDEA League's mission encompasses international support and outreach for patients and families, as well as collaboration with physicians, medical education, health care coordination, and research. The IDEA League is an excellent example of the impact of patient advocacy groups, the Internet, and social networking on the landscape of rare diseases.

  20. The Blindside Flick: Race and Rugby League

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available The issue of race was virtually beyond the touchline in Australian rugby league before the 1960s. It was a white man’s game. Institutionalised racism meant that few Aboriginal men played rugby league at the highest professional level. It is now presumed that race and racism has no place in a game where these questions have been historically ‘out of bounds’. The dearth of critical writing in rugby league history indicates that racism in the sport has been subject to a form of social blindness and deemed unworthy of study. Rugby league’s white exclusionist past and the denial of racism in the present era indicate habits of mind which may be described in league argot as the ‘blindside flick’.

    The University of Washington League of Astronomers (LOA) is an organization comprised of University of Washington (UW) undergraduate students. Our main goal is to share our interest in astronomy with the UW community and with the general public. The LOA hosts star parties on the UW campus and collaborates with the Seattle Astronomical Society (SAS) on larger Seattle-area star parties. At the star parties, we strive to teach our local community about what they can view in our night sky. LOA members share knowledge of how to locate constellations and use a star wheel. The relationship the LOA has with members of SAS increases both the number of events and people we are able to reach. Since the cloudy skies of the Northwest prevent winter star parties, we therefore focus our outreach on the UW Mobile Planetarium, an inflatable dome system utilizing Microsoft’s WorldWide Telescope (WWT) software. The mobile planetarium brings astronomy into the classrooms of schools unable to travel to the UW on-campus planetarium. Members of the LOA volunteer their time towards this project and we make up the majority of the Mobile Planetarium volunteers. Our outreach efforts allow us to connect with the community and enhance our own knowledge of astronomy.

  3. Science of rugby league football: a review.

    Gabbett, Tim J

    2005-09-01

    The purpose of this paper is to provide a comprehensive review of the science of rugby league football at all levels of competition (i.e. junior, amateur, semi-professional, professional), with special reference to all discipline-specific scientific research performed in rugby league (i.e. physiological, psychological, injury epidemiology, strength and conditioning, performance analysis). Rugby league football is played at junior and senior levels in several countries worldwide. A rugby league team consists of 13 players (6 forwards and 7 backs). The game is played over two 30 - 40 min halves (depending on the standard of competition) separated by a 10 min rest interval. Several studies have documented the physiological capacities and injury rates of rugby league players. More recently, studies have investigated the physiological demands of competition. Interestingly, the physiological capacities of players, the incidence of injury and the physiological demands of competition all increase as the playing standard is increased. Mean blood lactate concentrations of 5.2, 7.2 and 9.1 mmol . l(-1) have been reported during competition for amateur, semi-professional and professional rugby league players respectively. Mean heart rates of 152 beats . min(-1) (78% of maximal heart rate), 166 beats . min(-1) (84% of maximal heart rate) and 172 beats . min(-1) (93% of maximal heart rate) have been recorded for amateur, semi-professional and junior elite rugby league players respectively. Skill-based conditioning games have been used to develop the skill and fitness of rugby league players, with mean heart rate and blood lactate responses during these activities almost identical to those obtained during competition. In addition, recent studies have shown that most training injuries are sustained in traditional conditioning activities that involve no skill component (i.e. running without the ball), whereas the incidence of injuries while participating in skill-based conditioning

    Full Text Available Basketball is a sport that has a very long tradition in the territory of ex-Yugoslavia. The breakdown of the country led to a de- crease in quality of basketball in the newly created countries. The unsteadiness of quality of the teams in national leagues resulted in formation of the Regional Adriatic Basketball League (ABA in 2001. The main goal of this research was to measure the competitive balance in ABA, Spanish (ACB and National Basketball Association League (NBA. The competitive balance was calculated by using Ratio of Standard Deviation index (RSD and Herfindahl-Hirschman Index (HHI.The results of RSD showed that the most equable was ABA league, then came ACB league, while the most unequable was NBA league. The calculating of HHI index gave a different result. NBA is the most equable, then comes ABA league, and the last one is ACB league, which is the most unequable according to this parameter. ABA league has less quality than ACB and NBA league, but the results show that it is competitively the most balanced league. According to the RSD rates, NBA league is the most unequable. The main reason for that is a huge number of teams taking part in the league, which causes the unequable distribution of quality players. Ac- cording to HHI, NBA is the most equable. Reason for that are different mechanisms whose goal is to reach and maintain the competitive balance.

    To develop response criteria for juvenile dermatomyositis (DM). We analysed the performance of 312 definitions that used core set measures from either the International Myositis Assessment and Clinical Studies Group (IMACS) or the Paediatric Rheumatology International Trials Organisation (PRINTO) and were derived from natural history data and a conjoint analysis survey. They were further validated using data from the PRINTO trial of prednisone alone compared to prednisone with methotrexate or cyclosporine and the Rituximab in Myositis (RIM) trial. At a consensus conference, experts considered 14 top candidate criteria based on their performance characteristics and clinical face validity, using nominal group technique. Consensus was reached for a conjoint analysis-based continuous model with a total improvement score of 0-100, using absolute per cent change in core set measures of minimal (≥30), moderate (≥45), and major (≥70) improvement. The same criteria were chosen for adult DM/polymyositis, with differing thresholds for improvement. The sensitivity and specificity were 89% and 91-98% for minimal improvement, 92-94% and 94-99% for moderate improvement, and 91-98% and 85-86% for major improvement, respectively, in juvenile DM patient cohorts using the IMACS and PRINTO core set measures. These criteria were validated in the PRINTO trial for differentiating between treatment arms for minimal and moderate improvement (p=0.009-0.057) and in the RIM trial for significantly differentiating the physician's rating for improvement (p<0.006). The response criteria for juvenile DM consisted of a conjoint analysis-based model using a continuous improvement score based on absolute per cent change in core set measures, with thresholds for minimal, moderate, and major improvement.

    Why did the League of Nations ultimately fail to achieve widespread disarmament, its most fundamental goal? This article shows that the failure of the League of Nations had two important dimensions: (1) the failure to provide adequate security guarantees for its members (like an alliance); (2) the failure of this organization to achieve the disarmament goals it set out in the 1920s and 1930s. Thus, it was doomed from the outset to fail, due to built-in institutional contradictions. It can als...

    Full Text Available Por la falta de mercados para acomodar la producción nacional de leche, muchos productores locales están reduciendo significativamente el número de sus vacas lecheras, que están siendo comercializadas como vacuno corriente en ferias o mataderos a un tercio del precio que tenían pocos años atrás. Actualmente existe una sobreproducción de leche en el departamento de La Paz y cada vez se reduce la demanda de la población, así los agricultores se quedan con el producto teniendo que darle otra finalidad, pero en muchos casos se vuelve inevitable por las grandes cantidades de materia prima, para regular esta crisis, que se ha visto agudizada, por los bajos precios internacionales de este alimento de primera necesidad, situación que estaría impulsando el ingreso de leche y productos procedentes de las países vecinos, de ahí que, es necesario realizar esfuerzos e inversiones para innovar y producir nuevas variedades de artículos lácteos, pue permitan ampliar el mercado, y así competir en mejores condiciones respecto a los productos foráneos. Sería iniciativas que necesitan apoyo del Estado para su materialización, por ejemplo con dotación de infraestructura industrial, fuentes de energía, exenciones impositivas a la importación de tecnología, mayor flexibilidad fiscal y laboral, facilidades de financiamiento, medidas orientadas a fomentar la producción láctea del país en particular y la industria nacional en general. El mercado de la leche se ve afectado por la presencia de leche en polvo de contrabando o legalmente importada, situación que un paquete de leche importada en polvo cuesta hasta 20 Bs., mientras que la Planta Industrializadora de Leche (PIL-Andina comercializa en 41.70 Bs.

    This paper provides one of the few successful demonstrations of the efficiency of certain types of restrictions in the context of a joint venture. The joint venture we examine is the National Hockey League (NHL) in the 1980s, which was then composed of 21 separately owned teams. (It now has 30 teams.) The restriction we analyze is the NHL rule on franchise relocation. Before one can fully understand the effect of the restriction, one must understand the theory of how sports leagues operate an...

    Full Text Available La Zona 1 del Ecuador (provincias de Esmeraldas, Carchi, Ibarra y Sucumbíos es una región eminentemente ganadera, donde se alcanzan importantes volúmenes de leche, en especial, en las provincias andinas del Carchi e Ibarra. Casi un tercio de toda la leche se destinan a la producción de los diferentes tipos de quesos, generándose cantidades apreciables de suero de leche. Una parte importante del suero de leche se emplea en la alimentación animal, más otra, es vertida a los ríos, arroyos y quebradas, contaminando las fuentes naturales de agua. Regulaciones medioambientales más rigurosas, por un lado, y la toma de conciencia por otra, han puesto en evidencia la necesidad de transformar el suero de leche en efluentes menos contaminantes. Si adicionalmente se logra que como resultado de esta transformación se lograran obtener nuevos productos de mayor valor agregado que el propio suero de leche, se amortizaría en parte los recursos empleados en la transformación. En la presente revisión se exploran, desde las biotecnologías, algunas de las tecnologías disponibles y se discuten las vías para lograrlo en el contexto de la Zona 1 del Ecuador.

    Comparison of provider performance is commonly used to inform health care decision-making. Little attention has been paid to how data presentations influence decisions. This study analyzes differences in suggested actions by decision-makers informed by league tables or funnel plots. Decision-makers were invited to a survey and randomized to compare hospital performance using either league tables or funnel plots for four different measures within the area of cancer care. For each measure, decision-makers were asked to suggest actions towards 12-16 hospitals (no action, ask for more information, intervene) and provide feedback related to whether the information provided had been useful. Swedish health care. Two hundred and twenty-one decision-makers at administrative and clinical levels. Data presentations in the form of league tables or funnel plots. Number of actions suggested by participants. Proportion of appropriate actions. For all four measures, decision-makers tended to suggest more actions based on the information provided in league tables compared to funnel plots (44% vs. 21%, P decision-makers more often missed to react even when appropriate. The form of data presentation had an influence on decision-making. With league tables, decision-makers tended to suggest more actions compared to funnel plots. A difference in sensitivity and specificity conditioned by the form of presentation could also be identified, with different implications depending on the purpose of comparisons. Explanations and visualization aids are needed to support appropriate actions. © The Author 2016.

    2017-12-01

    Numerous reports have described players in professional American sports leagues who have been sidelined with a deep vein thrombosis (DVT) or a pulmonary embolism (PE), but little is known about the clinical implications of these events in professional athletes. To conduct a retrospective review of injury reports from the National Hockey League (NHL), Major League Baseball (MLB), the National Basketball Association (NBA), and the National Football League (NFL) to take a closer look at the incidence of DVT/PE, current treatment approaches, and estimated time to return to play in professional athletes. Descriptive epidemiology study. An online search of all team injury and media reports of DVT/PE in NHL, MLB, NBA, and NFL players available for public record was conducted by use of Google, PubMed, and SPORTDiscus. Searches were conducted using the professional team name combined with blood clot , pulmonary embolism , and deep vein thrombosis . A total of 55 venous thromboembolism (VTE) events were identified from 1999 through 2016 (NHL, n = 22; MLB, n = 16; NFL, n = 12; NBA, n = 5). Nineteen athletes were reported to have an upper extremity DVT, 15 had a lower extremity DVT, 15 had a PE, and 6 had DVT with PE. Six athletes sustained more than 1 VTE. The mean age at time of VTE was 29.3 years (range, 19-42 years). Mean (±SD) time lost from play was 6.7 ± 4.9 months (range, 3 days to career end). Seven athletes did not return to play. Players with upper extremity DVT had a faster return to play (mean ± SD, 4.3 ± 2.7 months) than those with lower extremity DVT (5.9 ± 3.8 months), PE (10.8 ± 6.8 months), or DVT with PE (8.2 ± 2.6 months) ( F = 5.69, P = .002). No significant difference was found regarding time of return to play between sports. VTE in professional athletes led to an average of 6.7 months lost from play. The majority of athletes were able to return to play after a period of anticoagulation or surgery. Those with an upper extremity DVT returned to play

  1. On the analysis of the beam energy stabilization in the Van de Graaff accelerator 'Lech'

    International Nuclear Information System (INIS)

    Bienkowski, A.; Jaskola, M.; Zemlo, L.

    1977-01-01

    In the Van de Graaff accelerator LECH the deviation of the beam energy from the desired value is detected by the standard analysing system consisting of the 90 0 bending magnet followed by a pair of slits. The amplified error signal from that slits is used to correct the high voltage at the terminal. Corrections of the fast component of the voltage instability are made via the corona-triode and for the slow component via adjustment of the belt charging current. In order to determine the maximum gain factors providing the stable operating conditions a definite transfer function has been adopted for the aforementioned two loop stabilizer. Next this function has been applied to the analysis of the stability of the feedback system. Although the calculation was made for parameters of the accelerator LECH, the same method is easily applicable to other Van de Graaff accelerators

    Full Text Available This paper presents the contributions to the process of formation of the League of Nations which, from sociological and legal premises present in the enlightened ideas of the German philosopher Krause, were designed and represented by two eminent Spanish Krausist jurists, Giner and Posada. First, we will analyse the influence of the teleological tradition of the Interessenjurisprudenz in Krausist legal philosophy, and the function of this iusphilosophical trend as a modernising and emancipating movement from the prevailing positivist formalism of the time. Secondly, we will delve into the basic principles of the Krausist sociological and legal theory which have been a major factor of Europeanisation, for which we will review his most scathing criticism to the European doctrines of imperial nationalism. Finally, we will address the role of Krausism in the promotion and defense of Wilson's Fourteen Points and the League of Nations, and its views on what should be subject to contestation in terms of international law.

    The first serious attempts to deal with public health problems in Greece were undertaken between 1925 and 1935. This period also witnessed setbacks to developments in public health, caused by the lack of welfare infrastructure for social relief, as well as extensive health problems brought about by the settlement in Greece of 1,300,000 refugees from Asia Minor. In 1928 following the example set by other European countries, the Liberal Government appealed to international health organisations for support in order to effectively deal with these problems. This contribution constitutes a case study addressing the following issues: a) the impact the League of Nations Health Organisation intervention had on the establishment of public health services; b) the framework for a collaboration of the Rockefeller Foundation and the League of Nations Health Organisation; and c) the factors that led to the failure of the health care reorganisation.

    1989-02-07

    The Planned Parenthood League of Massachusetts instituted a class action suit challenging the constitutionality of a statute requiring minors seeking an abortion to obtain parental consent or to persuade a judge of their maturity to give informed consent or that abortion would be in their best interest. In order to invoke judicial review, the plaintiffs moved their suit to federal court. The District Court dismissed the case on grounds that federal review power would interfere with state administration. On appeal, the First Circuit Court of Appeals decided that the plaintiffs could proceed with their action. The Circuit Court found that federal adjudication would not unduly interfere with state administration and remanded the case for further proceedings. Although it affirmed the statute's validity, the circuit court ruled that the plaintiffs must be allowed the opportunity to demonstrate the statute's unconstitutionality.

    Although physical activity brings a range of lifelong health benefits, it may also lead to injuries that pose a significant threat to health. It is particularly noticeable in people involved in professional sports where sport-related injuries commonly occur and are associated with intense exercise which aims to improve physical fitness. The article attempts to determine incidence of sports injuries reported by Plus League volleyball players, as well as to identify their most common types and causes. The research project involved 90 Plus League volleyball players aged 18-37 with the average age of 25.11 (SD±5.378). A method of diagnostic survey was applied to collect empirical data by means of questionnaire developed by the authors (researchers). The results were statistically analysed and verified with the analysis of variance (ANOVA) and χ2 test at the significance level (or critical P-value) of P≤0.05. Over 87% of the respondents suffered from at least one sport-related injury. In total, 362 injuries occurred, on average 4.02 injuries per one volleyball player. The most common sports injuries involved ankle or talocrural joint (46 injuries), knee and lower leg muscles (30), interphalangeal articulations of fingers (30) as well as shoulder joint. More than half of the injuries (57%) occurred twice or three times. Volleyball players commonly sustain injuries through contact with an opposing player in competition. Sport-specific injuries may also occur due to exhaustion, lack of rest and undertreated injuries. The most common volleyball-related injuries are primarily talocrural joint, hand and shoulder injuries. Common types of injuries that can affect volleyball players include muscles, joints and ligaments injuries, sprains and strains as well as bruises. Most of these injuries are caused by exhaustion, contact with an opposing player during competition and fatigue. The incidence of sport-related injuries seems to be influenced by such factors as somatic

    Concussion remains one of the inherent risks of participation in rugby league. While other injuries incurred by rugby league players have been well studied, less focus and attention has been directed towards concussion. The current review examined all articles published in English from 1900 up to June 2013 pertaining to concussion in rugby league players. Publications were retrieved via six databases using the key search terms: rugby league, league, football; in combination with injury terms: athletic injuries, concussion, sports concussion, sports-related concussion, brain concussion, brain injury, brain injuries, mild traumatic brain injury, mTBI, traumatic brain injury, TBI, craniocerebral trauma, head injury and brain damage. Observational, cohort, correlational, cross-sectional and longitudinal studies were all included. 199 rugby league injury publications were identified. 39 (20%) were related in some way to concussion. Of the 39 identified articles, 6 (15%) had the main aim of evaluating concussion, while the other 33 reported on concussion incidence as part of overall injury data analyses. Rugby league concussion incidence rates vary widely from 0.0 to 40.0/1000 playing hours, depending on the definition of injury (time loss vs no time loss). The incidence rates vary across match play versus training session, seasons (winter vs summer) and playing position (forwards vs backs). The ball carrier has been found to be at greater risk for injury than tacklers. Concussion accounts for 29% of all injuries associated with illegal play, but only 9% of injuries sustained in legal play. In comparison with other collision sports, research evaluating concussion in rugby league is limited. With such limited published rugby league data, there are many aspects of concussion that require attention, and future research may be directed towards these unanswered questions.

    We analyze a dynamic model of strategic interaction between a professional sport league that organizes a tournament, the teams competing to win it, and the broadcasters paying for the rights to televise it. Teams and broadcasters maximize expected profits, while the league's objective may be either to maximize the demand for the sport or to maximize the teams' joint profits. Demand depends positively on symmetry among teams (competitive balance) and how aggressively teams try to win (incentiv...

    Full Text Available El objetivo de este trabajo fue determinar las isotermas de adsorción y desorción de leche descremada en polvo a diferentes temperaturas. Se realizaron las experiencias a 15oC, 25oC y 40oC, en un amplio rango de humedades y actividades de agua propias de las condiciones habituales en que se desarrollan los procesos de secado, envasado y almacenamiento de la leche descremada en polvo. Los datos experimentales fueron correlacionados con dos modelos de ecuaciones referenciales: Modelo de GAB y Modelo de BET. Tanto para la adsorción como para la desorción se observó un mejor ajuste con el modelo de GAB. En particular, para la desorción, se pudo apreciar una buena correlación en las actividades de agua menores que 0,5 con el modelo de BET. Se observó un entrecruzamiento de las isotermas de adsorción a distintas temperaturas, lo cual influye en la relación entre el calor isostérico de adsorción en función del contenido de humedad.

    Presents the history of the Wanda-Lech and Pokoj mines until 1968 when they were fused, and development, technical progress and investment in the mines since 1968. Application of longwall equipment sets dates from 1965. The index of powered winning has reached 93.7% and that of powered loading - 97.4%. Seismoacoustic (1970/71) and microseismologic (1974) monitoring stations have been put into operation. The following investments have been realized since 1968: the main shaft Wanda and auxiliary shaft Lech II, two winning horizons, 3 main ventilation fans, a coal preparation plant, a bathhouse for 2,650 and a boiler house fuelled with run-of-mine methane. Mine communications, rail transport and storage facilitites have been modernized and extended. The mining area of the present Pokoj mine is shown in a scheme. Production before and after the take-over is compared: production increased from 1.969121 Mt in 1968 to 2.434740 Mt in 1987. A rehabilitation center (physical therapy, inhalation kinesthesia, hydrotherapy) cares for 2,000 patients annually. Further social services and facilities provided for the miners are described.

    Full Text Available El objetivo del estudio que se expone fue determinar cómo influye el consumo de forrajes ensilados, debidamente caracterizados, en la calidad microbiológica de la leche producida y su aptitud para la elaboración de quesos pasta dura. La producción de las vacas se controló durante dos años, en períodos quincenales, variando la alimentación para cada tratamiento; se extrajeron muestras de leche para analizar su calidad y se elaboraron quesos tipo "Reggianito". Los resultados mostraron que en silos de maíz "pasados" existe mayor contaminación de esporas que en silos de maíz "óptimos", en tanto que los silos de pulpa de citrus presentan contaminación mínima. No se observó correlación entre el nivel de esporas en leche y en silos. El recuento de microorganismos esporulados en los quesos no guarda relación proporcional con los encontrados en la leche utilizada como materia prima, por los cual los quesos no evidenciaron problemas durante la maduración.

    As we are proceeding towards an internet driven world, the impact of internet is increasing in our day to lives. This not only gives impact on the virtual world but also leave a mark in the real world. The social media sites contains huge amount of information, the only thing is to collect the relevant data and analyse the data to form a real world prediction and it can do far more than that. In this paper we study the relationship between the twitter data and the normal data analysis to predict the winning team in the NFL (National Football League).The prediction is based on the data collected on the on-going league which includes performance of each player and their previous statistics. Alongside with the data available online we are combining the twitter data which we extracted by the tweets pertaining to specific teams and games in the NFL season and use them alongside statistical game data to build predictive models for future or the outcome of the game i.e. which team will lose or win depending upon the statistical data available. Specifically the tweets within the 24 hours of match will be considered and the main focus of twitter data will be upon the last hours of tweets i.e. pre-match twitter data and post-match twitter data. We are experimenting on the data and using twitter data we are trying to increase the performance of the existing predictive models that uses only the game stats to predict the future.

  17. Euroscepticism in Italy: Evolution of Northern League Political Program

    Full Text Available Abstract: The article examines the key stages of the establishment of Italy’s Northern League as a rightwing hard eurosceptic party. Being initially a continual supporter of European integration and considering the transition to common currency as an opportunity available only to northern regions, which could secede and form an independent state, Northern League after losing the main point of its political agenda when the whole Italy joined the Economic and Monetary Union in 1998, became a eurosceptically-oriented party, which it is up to now. The authors dwell on the focal points of the party’s anti-EU program: Italy’s exit from the eurozone, the formation of Europe of macroregions, the reformation of supranational institutes and decision-making procedures. However, while confronting the Northern League policy with that of National Front in France and UKIP in the United Kingdom, the authors come to the conclusion that Euroscepticism for the former is just a sign of the shift in priorities rather than a strategy as for the latter. This can be explained by the fact that National Front and UKIP are still to fight for the place in the national mainstream, while Northern League has become its integral part long before. Nevertheless, under the new leadership of M.Salvini Northern League managed to become the fourth party on the national level according to the results of European parliament elections in 2014 and established itself as a significant power opponent to EU policy on a number of important issues, such as anti-Russian sanctions. Moreover, frequent visits of party members to Moscow and the party’s outspoken support of Russia on Crimea’s entrance into the Russian Federation provide an opportunity to consider Northern League a potential conductor of Russian interests in the European Union.

    Full Text Available Pastillas de leche or milk candies were prepared by separately evaporating fresh cow’s and carabao's milk and adding sugar to each until the mixture formed a soft ball.Statistical analysis of the results of organoleptic tests did not reveal significant differences in sweetness, flavor, odor, and general acceptability of these finished products. However, differences in color, body, and texture were noted. Carabao's milk scored high in terms of all organoleptic parameters and was favored by the panel of testers.The candies made from carabao's milk were also shown to have a higher fat and protein content than those made from cow’s milk; thus, the higher yield obtained in the case of carabao's milk.

Las conejas fueron hijas de 21 sementales y 53 madres las cuales produjeron 300 camadas y 2375 registros de producción de leche. La producción de leche (MY fue calculada pesando a la camada en 8 ocasiones, antes de después del amamantamiento. El análisis estadístico fue realizado utilizando un modelo animal individual, el cual incluyó los efectos fijos de raza, número de parto (1,2,3, número de pezones (8,9,10, mes de parto (enero-febrero, marzo-abril, mayo-junio, julio-agosto, estado de preñez (gestante y no gestante, las covariables días de lactancia, días de gestación y tamaño de camada, y los efectos directos y aleatorios. El promedio y la desviación estándar para la MY fue 145±64 gd-1. La varianza genética aditiva, la varianza del error y la heredabilidad de la MY fueron 247.86 g2, 1869.0 g2 y 0.12±0.02, respectivamente. En conclusión, la heredabilidad de la producción de leche fue baja, pero dentro del rango de los valores señalados en la literatura; lo cual sugiere que la selección genética debe hacerse considerando un alto número de relaciones de parentesco y métodos estadísticos de selección más precisos  para mejorar la producción de leche en conejas.

    Full Text Available La leche es uno de los alimentos de mayor importancia por ser rico en nutrientes y porque constituye la materia prima para la elaboración de una amplia gama de productos. Se ha demostrado que en leches pasteurizadas de marcas comerciales, pueden ocurrir contaminaciones postproceso, lo que representa un riesgo para la salud pública. Es por ello que en las últimas décadas, ha ganado importancia el uso de aditivos sintéticos u orgánicos como técnica complementaria durante el procesamiento de alimentos. La enzima glucosa oxidasa (GOX tiene amplio uso en la industria de alimentos gracias a sus propiedades antioxidante y antimicrobiana.

Por tal motivo, en el presente trabajo se planteó adicionar la enzima GOX en la leche y evaluar su efecto sobre el crecimiento de una cepa deEscherichia coli ATCC 25922. Se estandarizó la concentración de GOX y glucosa que ocasionaba la inhibición del crecimiento bacteriano en medio Luria-Bertani y en función de los resultados, se decidió utilizar la combinación de 2 U de GOX y 2,0 % de glucosa para agregarlos como aditivos en la leche y se establecieron dos sistemas: GOX/G sin pasteurizar y GOX/G pasteurizado. El crecimiento fue monitoreado por la técnica de contaje de colonias en placa-agar, a partir de 1 mL de cultivo a las 4, 6 y 24 h de incubación. Se encontró que los sistemas con GOX hasta las 6 horas presentaron efectos similares, inhibiendo significativamente el crecimiento de la bacteria, mientras que a las 24 h ya no se observó dicha inhibición, pero sí que el sistema con GOX pasteurizada exhibió una población menor que el sistema GOX sin pasteurizar. Estos hallazgos proyectan a la enzima GOX como una alternativa para la conservación de la leche, tanto cruda como pasteurizada.

  13. Hybrid geomorphological maps as the basis for assessing geoconservation potential in Lech, Vorarlberg (Austria)

    2013-04-01

    Geoconservation potential is, in our approach, closely linked to the spatial distribution of geomorphological sites and thus, geomorphological inventories. Detailed geomorphological maps are translated, using a standardized workflow, into polygonal maps showing the potential geoconservation value of landforms. A new development is to semi-automatically extract in a GIS geomorphological information from high resolution topographical data, such as LiDAR, and combine this with conventional data types (e.g. airphotos, geological maps) into geomorphological maps. Such hybrid digital geomorphological maps are also easily translated into digital information layers which show the geoconservation potential in an area. We present a protocol for digital geomorphological mapping illustrated with an example for the municipality of Lech in Vorarlberg (Austria). The protocol consists of 5 steps: 1. data preparation, 2. generating training and validation samples, 3. parameterization, 4. feature extraction, and 5. assessing classification accuracy. The resulting semi-automated digital geomorphological map is then further validated, in two ways. Firstly, the map is manually checked with the help of a series of digital datasets (e.g. airphotos) in a digital 3D environment, such as ArcScene. The second validation is field visit, which preferably occurs in parallel to the digital evaluation, so that updates are quickly achieved. The final digital and coded geomorphological information layer is converted into a potential geoconservation map by weighting and ranking the landforms based on four criteria: scientific relevance, frequency of occurrence, disturbance, and environmental vulnerability. The criteria with predefined scores for the various landform types are stored in a separate GIS attribute table, which is joined to the attribute table of the hybrid geomorphological information layer in an automated procedure. The results of the assessment can be displayed as the potential

    Introducción. La leche materna es esencial para el desarrollo del ser humano, pero puede contener sustancias tóxicas provenientes de la contaminación ambiental, especialmente en las áreas mineras.Objetivo. Determinar la prevalencia de la contaminación con mercurio de la leche materna de mujeres lactantes residentes en los municipios con explotación minera de oro.Materiales y métodos. Se hizo un estudio transversal de 150 madres lactantes de cuatro municipios mineros de Antioquia (El Bagre, Segovia, Remedios y Zaragoza), a quienes se les hizo una encuesta sobre factores sociodemográficos, ocupacionales y ambientales relacionados con el mercurio, y se les tomaron muestras de leche materna, de orina y de cabello. Se calculó el promedio de la concentración de mercurio y las prevalencias municipales de contaminación.Resultados. El promedio de la concentración de mercurio en la leche materna fue de 2,5 (± desviación estándar 9,2) μg/L. La prevalencia de muestras de leche materna con niveles altos de mercurio fue de 11,7 %.Conclusión. En este estudio se evidencia un grave problema en las regiones mineras auríferas de Antioquia por el efecto de la contaminación con mercurio en sectores de la población más vulnerable.

    Full Text Available PESAR DE LA EXISTENCIA DE MERCADOS DINÁMICOS DE LECHE EN EL municipio de Matiguás –con el potencial de reducir la pobreza en esta zona rural– los hogares enfrentan dificultades para articularse a la cadena de la leche y se ven limitados de disfrutar los posibles beneficios que podrían obtener al participar. La falta de infraestructura y de servicios de apoyo al intercambio limita el desempeño de la cadena, y a su vez, bloquea el acceso de los hogares a la misma, creando procesos de exclusión o permitiendo el acceso a la cadena bajo condiciones desfavorables. Algunos hogares, enfrentando procesos de exclusión económica y social, participan en transacciones entrelazadas patrón-clientelistas como única manera de acceder a la cadena de la leche. Esta situación provoca la segmentación de la cadena de la leche: los diferentes hogares operan en diferentes canales para conectarse a la cadena, cada uno con su propia lógica productiva y comercial, y desempeño distributivo y participativo. En este contexto, presentamos un diagnóstico exploratorio acerca de las oportunidades y limitantes de los medios de vida de los hogares rurales de Matiguás en presencia de una fuerte dinámica en la cadena de la leche.

    2016-01-01

    Background Preventing concussion in sport is a global challenge. To assess community-level adult male Australian Football players’ views on following the Australian Football League's (AFL) concussion guidelines. Methods 3 focus groups, each comprising 6 players from 1 regional league, were conducted until saturation of issues raised. Discussions followed a semistructured script and were audio-recorded and transcribed verbatim. Thematic analysis was conducted by 2 coders independently. Results Identified advantages of the guidelines included highlighting the seriousness of concussion; changing the culture around playing with concussion and shifting return-to-play decision responsibility from players to others. Disadvantages included players being removed from play unnecessarily; removal of players’ rights to decide if they are fit to play and players changing their behaviours to avoid being removed from play. Identified facilitators to guideline use included local league enforcement; broad information dissemination and impartial medically trained staff to assess concussion. Identified barriers to guideline use included players’ desire to play at all costs; external pressure that encouraged players to return to play prematurely; and inconvenience and cost. Conclusions Players generally understand that the AFL concussion guidelines protect their long-term welfare. However, their desire to play at all costs and help their team win is a common barrier to reporting concussion and adhering to guidelines. Leagues should take a lead role by mandating and enforcing the use of the guidelines and educating coaches, game day medical providers and players. The return-to-play component of the guidelines is complex and needs further consideration in the context of community sport. PMID:28890801

    Full Text Available The All-India Muslim League (AIML was formed in 1906, with the primary aim to improve the educational and socioeconomic status of Muslims. Allama Shibli Nu‘mani (1857-1914 put forward an argument in support of Muslims recovering from the political stupor into which they had fallen after the British suppression of the 1857 uprising. He encouraged Muslims to participate in democratic politics in India, departing from the educational focus of his mentor, Sir Saiyid Ahmad Khan (1817-1898. Shibli advanced a strong critique of the Muslim League’s limited ambitions in comparison with the Indian National Congress (INC. His critique, notably in ironic and emotive poetry, significantly contributed to the national discussion pertaining to the Muslim League’s reform and restructure. Based on Shibli’s original writings, this paper analyses his critique of the Muslim League and his efforts to overhaul its structure and policies. It examines the response of the Muslim League to these critiques and studies the extent to which its structure and policies changed.

    Se evaluó un sistema de crianza artificial en terneras Lucerna con una mezcla de leche descremada y suero de mantequilla, en la Hacienda "Lucerna", en Bugalagrande, Valle del Cauca, Colombia. Se distribuyeron 18 animales en dos grupos en un diseño completamente al azar. El grupo control recibió, durante 110 días, 320 kg de leche entera y el grupo experimental, 320 kg de una mezcla de 50% de leche descremada y 50% suero de mantequilla. Se estudiaron los promedios del peso corporal, perímetro torácico y la alzada de las terneras. Los análisis de varianza no indicaron diferencias significativas entre los tratamientos, pero éstas fueron altamente significativas cuando se analizaron en el tiempo y en la interacción tratamientos por tiempo, lo que presupone que los dos grupos experimentales, tendieron a presentar diferencias en sus respuestas biológicas durante la época en que se suministraron. Pruebas de regresión por polinomios ajustados, confirmaron los resultados de los análisis de varianza. Se infiere que por el uso de leche descremada y suero de mantequilla se puede obtener un crecimiento y desarrollo normal en terneras Lucerna.

    Full Text Available In this work, the effect of temperature cycling on emulsions formulated with reconstituted soy milk, sunflower oil and high melting point milk fat was analysed. The emulsions were prepared at 60 ºC , stored at 4 ºC (3 h, warmed at 40 ºC or 50 ºC (30 min and afterwards recooled at 4 ºC (2h. Although solid fat content of emulsions did not raised after tempering at 40 ºC , increase of G' and G'' was observed only in those formulated with 40 % lipid phase. This phenomenon was attributed to droplet aggregation due to partial melting, recrystallization and reordering of fat crystals in oil droplets. The main droplet destabilization mechanism was the partial coalescence; it was corroborated by nuclear magnetic resonance, differential scanning calorimetry and droplet size distribution studies. On the other hand, the consistency of 20 % of lipid phase emulsion did not increased. Low droplet concentration disfavoured the partial coalescence of droplets. Similar assays on cream at 40 ºC and cream-like soy milk emulsions at 50 ºC , did not show rheological modifications, due to almost total melting of milk fat during tempering.En este trabajo se analizó el efecto de ciclos calentamiento-enfriamiento sobre cremas preparadas a 60 ºC con leche de soja en polvo reconstituida, aceite de girasol y grasa láctea y almacenadas posteriormente a 4 °C durante 3 horas.

    Pliley, Jessica R

    2010-01-01

    This article examines the League of Nations Advisory Committee on the Trafficking of Women and Children (CTW) to assess the impact of international feminists on the interwar anti-sex trafficking movement. It argues that women who were firmly embedded in the transnational and international women's rights movement built a coalition on the CTW to ensure the prominence of the feminist abolitionist position of sex trafficking in the 1920s. This position was defined by calls for equal standards of morality between the sexes, resistance to laws that treated prostitutes as a group and infringed on their human rights, and unwavering demands for the abolition of state-regulated prostitution. Changes in the personnel and bureaucratic structure of the CTW and the rising tide of nationalism served to undermine the feminist abolitionists' position in the League in the 1930s.

    2015-01-01

    To describe the metabolic demands of rugby league match play for positional groups and compare match distances obtained from high-speed-running classifications with those derived from high metabolic power. Global positioning system (GPS) data were collected from 25 players from a team competing in the National Rugby League competition over 39 matches. Players were classified into positional groups (adjustables, outside backs, hit-up forwards, and wide-running forwards). The GPS devices provided instantaneous raw velocity data at 5 Hz, which were exported to a customized spreadsheet. The spreadsheet provided calculations for speed-based distances (eg, total distance; high-speed running, >14.4 km/h; and very-high-speed running, >18.1 km/h) and metabolic-power variables (eg, energy expenditure; average metabolic power; and high-power distance, >20 W/kg). The data show that speed-based distances and metabolic power varied between positional groups, although this was largely related to differences in time spent on field. The distance covered at high running speed was lower than that obtained from high-power thresholds for all positional groups; however, the difference between the 2 methods was greatest for hit-up forwards and adjustables. Positional differences existed for all metabolic parameters, although these are at least partially related to time spent on the field. Higher-speed running may underestimate the demands of match play when compared with high-power distance-although the degree of difference between the measures varied by position. The analysis of metabolic power may complement traditional speed-based classifications and improve our understanding of the demands of rugby league match play.

    Despite numerous studies which have been done regarding soccer injuries worldwide, there is lack of available data considering the epidemiology of injuries in the Iranian soccer premier league, although it is the most popular sport in the country. The main goal of this research was to determine the incidence of physical injuries in the studied population, considering other characteristics such as site, type and mechanism as well. Twenty one adult male professional soccer players (age 24±3), members of a team (Tehran-Pas) participating in Iranian premier league, were followed during a 4-month period. The injury characteristics and exposure times were recorded by the team physician during all the matches and training sessions. The total exposure time was 2610 playing hours (2352 h of training versus 258 h of competition). Eighty six percent of the injuries were acute. Incidence of acute injuries was 16.5 (95% CI: 12-22) per 1000 hours of playing (11.5 per 1000 hrs of training and 62 per 1000 hrs of competition). The most common types of injuries were strains followed by contusions, each of which constituted 30% of acute injuries. More than 80% of injuries occurred in lower limbs, especially in thigh and groin regions. Nearly 60% of acute injuries occurred in dominant side of the body, and collision was the reason of about half of the acute injuries. Severity of more than 70% of the injuries was minor. On average each injury had led the player being off the field for about 10 days. The incidence of injury in this research is in range of numbers obtained in important international tournaments but the rate of injuries during training sessions is higher than comparable studies.

    Full Text Available La leche cruda, por sus componentes nutricionales se puede considerar un alimento completo; sin embargo, su estado líquido y el manejo dado, puede convertir al producto en un sustrato ideal para el desarrollo de microorganismos y transmisión de enfermedades. El objetivo de este trabajo fue determinar algunas características de los actores que hacen parte de la cadena de leche cruda en el Municipio de Popayán, a partir de las cuales se comprobó el cumplimiento o no, de las recomendaciones técnicas establecidas por la normatividad vigente, para cada eslabón. Para llevar a cabo este proceso, se encuestó a cada uno de los actores de la cadena láctea en Popayán y municipios cercanos, para posteriormente proceder a su análisis. Se obtuvo información de 2.305 actores, de los cuales 2.014 fueron consumidores (hogares, 195 correspondieron a productores, 60 a procesadoras artesanales (9 de empresas legalmente constituidas y 51 sin registro mercantil y 36 fueron actores del eslabón de acopio y distribución (25 ruteros y 11 distribuidores. Los resultados relacionados con las normas técnicas, obtenidos en cada eslabón, permitieron determinar que el 100% de los actores, no cumplen todas las recomendaciones técnicas, por lo cual son considerados actores informales.

    Full Text Available Se realizó un estudio en la UBPC Aguadita, del municipio Rodas _provincia Cienfuegos, Cuba_, con el objetivo de elaborar un plan de manejo sostenible del suelo para incrementar la producción de leche. Se utilizó la guía contenida en el manual de procedimientos para la implementación del manejo sostenible de tierra. Los pasos de la guía permitieron concebir una investigación no experimental, de tipo correlacional/múltiple, en la que se utilizaron métodos teóricos y prácticos con sus correspondientes técnicas (entrevistas, encuestas, revisión documental, observación directa; y se realizaron mediciones en el lugar, con la aplicación de diez herramientas metodológicas. Se demostró que la baja producción de leche en la UBPC es causada fundamentalmente por la degradación de los suelos, la mala calidad de los pastos y la deficiente gestión del conocimiento, lo que coincide con la principal barrera para la aplicación del manejo sostenible de tierra. A partir de estos resultados se elaboró el plan de manejo sostenible, como herramienta que contribuye a desarrollar acciones que mitiguen el impacto negativo de la degradación de suelos en el rendimiento lechero de la unidad.

J Strength Cond Res XX(X): 000-000, 2018-The purpose of this study was to determine if elite football players are becoming bigger, faster, and stronger over the past decade by analyzing individual performances at the National Football League's (NFL) Combine. This study was conducted with (N = 1,263) subjects from the 1999-2000 (99-00) NFL Combines (n = 635) and the 2015-2016 (15-16) NFL Combines (n = 628) separated by position. Data were collected for height, weight, 40-yd (36.58 m) dash, NFL 225 lb. (102.06 kg) repetitions test, vertical jump (VJ), broad jump (BJ), pro-agility shuttle, and 3-cone drill. Statistical significance between the years for all subjects participating in the NFL Combine was found for the 40-yd dash (99-00: mean ± SD = 4.85 ± 3.2; 15-16: 4.80 ± 3.5; p = 0.002) and VJ (99-00 = 32.30 ± 4.08; 15-16: 32.86 ± 4.17; p = 0.028) at the alpha p 0.05) for weight or height found across all subjects by combine years. Results indicate that elite football players have improved their performance, when comparing results from 1999-2000 to 2015-2016. These finding may be beneficial to NFL franchises in their prospective player assessments.

    Full Text Available Los adsorbentes han sido utilizados ampliamente para prevenir las micotoxicosis y la transferencia d e toxinas o sus metabolitos dentro de la cadena alimentaria. Particularmente, se unen a las aflatoxinas dentro del tracto gastrointestinal de los rumiantes, disminuyendo su biodisponibilidad y la transferencia de aflatoxin a M 1 (AFM 1 a la leche. El presente estudio se desarrolló para evaluar dos métodos de exposición a aflatoxina B 1 en vacas Holstein y monitorear la transferencia AFM 1 a la leche. Adicionalmente, se analizó el potencial de tres adsorbentes de aflatoxinas en ambos experimentos. Los resultados mostraron una tasa de trasferencia de AFB 1 a AFM 1 / día de 3.35 y 1.8 % en los dos experimentos respectivamente. La transferencia estimada de AFM 1 en la leche observada en el segundo método fue cercana a las obtenidas de vacas alimentadas con alimentos natura lmente contaminados con aflatoxinas. A diferencia de los glucomananos de paredes cel ulares de levaduras, ambos adsorbentes de aluminosilicatos disminuyeron significativamente los niveles de AFM 1 en la leche ( P <0.05.

    We investigated the effects of a circadian disadvantage (i.e. playing in a different time zone) on the winning percentages in three major sport leagues in North America: the National Basketball Association, the National Hockey League and the National Football League. We reviewed 5 years of regular season games in the National Basketball Association, National Hockey League and National Football League, and noted the winning percentage of the visiting team depending on the direction of travel (west, east, and same time zone) and game time (day and evening games). T-tests and analysis of variance were performed to evaluate the effects of the circadian disadvantage, its direction, the number of time zones travelled, and the game time on winning percentages in each major league. The results showed an association between the winning percentages and the number of time zones traveled for the away evening games, with a clear disadvantage for the teams travelling westward. There was a significant difference in the teams' winning percentages depending on the travelling direction in the National Basketball Association (F 2,5908  = 16.12, P < 0.0001) and the National Hockey League (F 2,5639  = 4.48, P = 0.011), and a trend was found in the National Football League (F 2,1279  = 2.86, P = 0.058). The effect of the circadian disadvantage transcends the type of sport and needs to be addressed for greater equity among the western and eastern teams in professional sports. These results also highlight the importance of circadian rhythms in sport performance and athletic competitions. © 2017 European Sleep Research Society.

    The aim of this study was to examine brain neurometabolite concentrations in retired rugby league players who had a history of numerous self-reported concussions. Participants were 16 retired professional rugby league players (ages 30-45 years) with an extensive history of concussion and participation in contact sports, and 16 age- and education-matched controls who had no history of neurotrauma or participation in contact sports. All completed a clinical interview, psychological and cognitive testing, and magnetic resonance spectroscopy (MRS) investigation. MRS voxels were placed in posterior cingulate grey matter and parietal white matter. Neurometabolite concentrations were quantified using LCModel. It was hypothesized that retired athletes would differ on N-acetyl aspartate, myo-inositol, choline, glutamate, and glutathione. Retired players had significantly lower concentrations of grey matter glutathione (p=0.02, d=0.91). They did not significantly differ in concentrations of other neurometabolites. There were no significant differences between groups on measures of depression, anxiety, or cognitive functioning.

    Rodrigo Fernández Pavez

    2017-11-01

    Full Text Available Introducción: dos factores importantes han sido descritos como contribuyentes en la aparición de fatiga durante el ejercicio físico: la disminución de las reservas de glucógeno muscular y la pérdida de agua con electrolitos a través del sudor, que favorecen la deshidratación. Debido a esto, la reposición de líquidos y electrolitos posterior al ejercicio físico se transforma en la prioridad para restablecer la homeostasis corporal alterada durante el ejercicio físico. Por su composición nutricional, la leche parece ser una buena alternativa natural como bebida rehidratante posterior al ejercicio físico. Objetivo: comparar la efectividad como bebida de rehidratación de la leche descremada chocolatada contra una bebida deportiva artificial en militares, a partir de la hipótesis de que la leche descremada chocolatada tiene iguales o mejores efectos sobre la hidratación post ejercicio, que una bebida deportiva artificial. Método: 30 militares (23,0 ± 3,2 años se dividieron en 2 grupos: 1 rehidratación con bebida deportiva con 6 % de carbohidratos y relación de Na/K 2:1 (grupo ISO. Rehidratación con leche descremada chocolatada (grupo LECHE. Se evaluó la retención de fluidos a través del peso corporal y la gravedad específica de la orina (GEO antes y después del ejercicio físico y posterior a las 2 horas de rehidratación. Resultados: se encontraron diferencias significativas (p< 0,05 en la retención de fluidos en el grupo LECHE comparado con el grupo ISO. No hubo diferencias significativas entre la GEO de ambos grupos. Conclusión: Los resultados muestran que la rehidratación con leche descremada es más efectiva en la retención de fluidos y recuperación del peso previo al ejercicio que la bebida deportiva.

    2010-01-01

    Full Text Available Estudios en animales experimentales señalan que el ácido linoleico conjugado (CLA por sus siglas en inglés, posee propiedades benéficas para la salud. Los productos derivados de rumiantes como carne y leche son la mayor fuente natural de CLA, y su contenido en leche puede ser influenciado por varios factores como la alimentación y el sistema de producción. Este trabajo evalúo el contenido de CLA en leche de vacas Holstein estabuladas en el municipio de Hermosillo, Sonora durante el verano, donde se registran temperaturas superiores a los 40 °C. Se obtuvieron muestras de leche de 120 vacas. El perfil de ácidos grasos y CLA en leche fueron determinados por cromatografía de gases. La producción promedio de leche fue 15.8 ± 0.5 kg/día, con 1.91 ± 0.06 % de grasa, 4.30 ± 0.2 % de lactosa, 3.34 ± 0.03 % de proteína, y de 10.4 ± 0.09 % de sólidos totales. El contenido de ácidos grasos insaturados fue mayor (P<0.05 en agosto, respecto a los meses de junio y julio. La concentración promedio del isómero cis- 9, trans-11 CLA encontrada fue de 9.36 mg/g de grasa (junio 10.78 ± 0.41, julio 8.50 ± 0.37 y agosto 10.16 ± 0.39, considerada alta y equiparable a lo reportado en otros países con clima templado. La cantidad de CLA en leche puede ser atribuida a la dieta por la presencia del 58.8 % de alfalfa, rica en ácidos grasos precursores del CLA (linoleico y linolénico durante el verano.

En el BON estos valores fueron 278 kg, 114 días de lactancia, 4,6% de grasa y 3,9% de proteína en la leche. Los porcentajes de heterosis con base en el promedio de razas fueron: 4,20%, 16,70%, -12,80% y -12.20% para producción de leche, duración de lactancia, porcentaje de grasa y porcentaje de proteína respectivamente, todos altamente significativos (P<0,01. Los porcentajes de heterosis tomando como referencia la raza Holstein fueron: -45,20%, -21,50%, 6,25% y 5,35% en el mismo orden de las características anteriormente citadas. En general, los porcentajes de heterosis fueron menores a los reportados en la literatura. Se concluye que el F1 ha desempeñado un papel preponderante en el mejoramiento de la calidad de la leche en el Centro Paysandú, presentado porcentajes de heterosis medios para la calidad de la leche con referencia a la raza Holstein. Esto puede ser confirmado al analizar el porcentaje de grasa desde 1994, cuando parieron las primeras vacas F1, presentado coeficiente de regresión y correlación de 0,02 y 0,55 respectivamente. En la actualidad, el promedio para el porcentaje de grasa y proteína en el hato es de 3,45% y 3,03% respectivamente. Si sólo se tuviese la raza Holstein, estos porcentajes serían de 3,20% y 2,80%, significativamente menores.

    Full Text Available Se comparó la eficiencia alimenticia, expresada en crecimiento y desarrollo corporal de dos planes de alimentación láctea en la crianza artificial de terneras en la Hacienda "Lucerna", Bugalagrande, Colombia. Se usaron 20 animales, en un diseño completamente al azar, divididos en dos grupos, los cuales se formaron en el tiempo. El grupo control recibió el plan tradicional Lucerna de 320 kg de leche en 110 días y el otro, el de 214 kg de leche durante 50 días. Los análisis de varianza del peso corporal, perímetro torácico y alzada de las terneras no encontraron diferencias estadísticas entre los tratamientos; pero éstas fueron altamente significativas cuando se estudiaron en el tiempo y en la interacción tratamientos por tiempo, lo cual supone que los planes alimenticios, en la época en que se suministraron, tendieron a presentar diferencias en las respuestas biológicas entre los dos grupos experimentales. Los resultados indicaron que con cantidades reducidas de leche es probable obtener crecimiento y desarrollo similar al que se obtiene con el plan tradicional.This work evaluated feed efficiency, expressed as growth and body development, comparing two milk feeding plans in the artificial nurturing of calves at the Hacienda "Lucerna", Bugalagrande, Colombia. Twenty animals were used in a completely randomized design and were assigned to two treatment groups, the control group which received the traditional Lucerna plan of 320 kg of milk in 110 days and the second group which received milk quantities of 214 kg in 50 days. Analysis of variance was used to determine differences in body weight, perimeter at the torax, and height. No statistical significant differences were found, but when time and time by treatment interactions were evaluated, the differences were highly significant, leads to suggest that the feeding plans tended to show differences in the biological response of the experimental groups in the particular period of time

    Scientific injury data in men's professional team handball injuries are rare and even less scientific information exists on injury prevention. In 2011, Germany's national second team handball league was restructured by merging the existing two regional leagues into one league. This study evaluates the injury patterns in professional team handball and compares the injury rates between the first and second league before and after the restructure. All players of Germany's national first and second men's team handball leagues have mandatory trauma insurance with the same insurance company. This retrospective cohort study analysed the injury data of three consecutive seasons 2010-2013 using standardized injury definitions. 1194 professional team handball players were included in this study. The majority of severe injuries affected the lower extremities, shoulders, and hands. The average injury incidence significantly differed between the first (4.9 injuries per 1000 h) and the second league (3.9 per 1000 h, p handball league and presents details on prevalence, incidence, and patterns of injury in professional men's team handball. This study is an important basis for developing injury prevention strategies that should focus on the shoulders, hands, and lower extremities and on reducing the number of matches and travel burden.

    Background: Os styloideum describes an accessory carpal ossicle between the trapezoid, the capitate, and the second and third metacarpals. Injuries to this tissue have been described as part of the carpal boss syndrome. While the etiology of os styloideum remains uncertain, it may represent a physiologic response to altered loading forces in the wrist, similar to the development of cam-type deformity in the hips of ice hockey players or the Bennett lesion in the shoulders of baseball pitchers. Hypothesis: Professional hockey players will have a higher prevalence of os styloideum compared with the general population. Study Design: Case series. Level of Evidence: Level 4. Methods: A retrospective review of 16 professional hockey players from 4 different National Hockey League (NHL) teams who underwent unilateral imaging of the wrist was performed. Seventeen wrists were reviewed for the presence of os styloideum. Results: Thirteen of 16 players (81%) had an os styloideum, representing an increased prevalence compared with the general population. Previous clinical and cadaveric studies estimated a general prevalence of up to 19% (P < 0.001). For the 10 players who had their leading wrist scanned, 9 had an os styloideum (90%). Ten of 11 (91%) players demonstrated a bone marrow edema pattern within the metacarpal and the os styloideum on magnetic resonance imaging. There was no significant association between the presence of an os styloideum and the player’s position, leading wrist, or years in the league. Conclusion: There appears to be an increased prevalence of os styloideum among NHL players, and team physicians should consider this finding while formulating a differential diagnosis for dorsal wrist pain. Clinical Relevance: This study identified NHL players as having an increased prevalence of os styloideum compared with the general population. By doing so, these findings represent an opportunity to enhance our understanding of the etiology, clinical significance

  11. Technology and Organisation of Inka Pottery Production in the Leche Valley. Part II: Study of Fired Vessels

    2003-01-01

    Ceramic finds from the Inka workshops at Tambo Real and La Vina in the Leche Valley in northern Peru were studied by Moessbauer spectroscopy, thin section microscopy and X-ray diffraction. Sherds of Inka style vessels and of local style vessels can be distinguished by their shape, although local techniques appear to have been used in making both types. A reconstruction of the firing techniques by scientific studies of the ceramic material does not reveal a substantial difference in material or in the firing of both forms, although high firing temperatures were necessary to achieve sufficient stability of the large Inka style vessels. It cannot be decided whether the smaller local vessels were fired together with the Inka vessels or separately. Most of the variation in the maximum firing temperature can be explained with the normal temperature and atmosphere fluctuations in an open pit kiln.

    With rising participation in youth sports such as baseball, proximal humeral epiphysiolysis, or Little League shoulder (LLS), is being seen with increasing frequency. However, there remains a paucity of literature regarding the causes, natural history, or treatment outcomes of LLS. To analyze the demographic, clinical, and diagnostic features of a population of LLS patients, with an emphasis on identifying underlying risk factors for the development and recurrence of LLS after nonoperative treatment. Case series; Level of evidence, 4. A departmental database at a high-volume regional children's hospital was queried to identify cases of LLS between 1999 and 2013. Medical records were reviewed to allow for analysis of age, sex, athletic information, physical examination and radiologic findings, treatment details, clinical course, and rates of recurrence. Ninety-five patients (93 males, 2 females; mean age, 13.1 years; range, 8-16 years) were diagnosed with LLS. The number of diagnosed cases increased annually over the study period. All patients had shoulder pain with overhead athletics; secondary symptoms included elbow pain in 13%, shoulder fatigue or weakness in 10%, and mechanical symptoms in 8%. While the majority of patients (97%) were baseball players (86% pitchers, 8% catchers, 7% other positions), a small subset (3%) were tennis players. On physical examination, 30% were reported to have glenohumeral internal rotation deficit (GIRD), defined as a decreased arc of rotational range of motion of the shoulder. Treatment recommendations included rest in 99% of cases, physical therapy in 79% (including 100% of patients with GIRD), and position change upon return to play in 26%. Average time to full resolution of symptoms was 2.6 months, while average time to return to competition was 4.2 months. Recurrent symptoms were reported in 7% of the overall cohort at a mean of 7.6 months after initial diagnosis. The odds of recurrence in the group with diagnosed GIRD (14

    The metabolic requirements of a rugby league match simulation protocol and the timing of carbohydrate provision on glycogen re-synthesis in damaged muscle were examined. Fifteen (mean±SD: age 20.9±2.9 year, body-mass 87.3±14.1kg, height 177.4±6.0cm) rugby league (RL) players consumed a 6gkgday-1 CHO diet for 7-days, completed a time to exhaustion test (TTE) and a glycogen depletion protocol on day-3, a RL simulated-match protocol (RLMSP) on day-5 and a TTE on day-7. Players were prescribed an immediate or delayed (2-h-post) re-feed post-simulation. Muscle biopsies and blood samples were obtained post-depletion, before and after simulated match-play, and 48-h after match-play with PlayerLoad and heart-rate collected throughout the simulation. Data were analysed using effects sizes±90% CI and magnitude-based inferences. PlayerLoad (8.0±0.7 AUmin-1) and %HRpeak (83±4.9%) during the simulation were similar to values reported for RL match-play. Muscle glycogen very likely increased from immediately after to 48-h post-simulation (272±97 cf. 416±162mmolkg-1d.w.; ES±90%CI) after immediate re-feed, but changes were unclear (283±68 cf. 361±144mmolkg-1d.w.; ES±90%CI) after delayed re-feed. CK almost certainly increased by 77.9±25.4% (0.75±0.19) post-simulation for all players. The RLMSP presents a replication of the internal loads associated with professional RL match-play, although difficulties in replicating the collision reduced the metabolic demands and glycogen utilisation. Further, it is possible to replete muscle glycogen in damaged muscle employing an immediate re-feed strategy. Copyright © 2017 Sports Medicine Australia. Published by Elsevier Ltd.

    By maintaining phosphate and calcium homeostasis, vitamin D is critical for bone health and possibly physical performance. Hence, vitamin D is important to athletes. Few studies have investigated vitamin D levels in relation to fractures and performance in athletes, and no published study has included a multiracial sample of professional American football players. To assess vitamin D levels, including the prevalence of vitamin D deficiency/insufficiency, in professional American football players and to evaluate the association of vitamin D levels with race, fracture history, and the ability to obtain a contract position, which may be a marker for athletic performance. Cohort study; Level of evidence, 3. Serum vitamin D levels of 80 professional football players from a single team in the National Football League were obtained during the 2011 off-season (mean age, 26.5±3.7 years; black, n=67 [84%]). These levels were used to compare injury reports from the 2011-2012 and 2012-2013 seasons. Statistical analyses were performed to test if vitamin D levels were related to race, fracture history, and the ability to obtain a contract position. Mean vitamin D level was 27.4±11.7 ng/mL, with significantly lower levels for black players (25.6±11.3 ng/mL) versus white players (37.4±8.6 ng/mL; F 1,78=13.00, P=.001). All athletes who were vitamin D deficient were black. When controlling for number of professional years played, vitamin D levels were significantly lower in players with at least 1 bone fracture when compared with no fractures. Players who were released during the preseason because of either injury or poor performance had significantly lower vitamin D levels than did players who played in the regular season. Black professional football players have a higher rate of vitamin D deficiency than do white players. Furthermore, professional football players with higher vitamin D levels were more likely to obtain a contract position in the National Football League

    Academic leagues have been consolidated as instruments of medical teaching and for the introducing of medical students to practice of specialties, including anesthesiology. As the role of leagues in the development process of competencies and learning of their students is not well known, the learning of members of an anesthesiology academic league was evaluated after participating in its activities for one year. Students of an anesthesiology academic league were followed up from March to December 2010 and evaluated through objective cognitive tests of multiple choice applied before the beginning of activities and after their conclusion. Attendance in activities and epidemiologic profile of students were correlated with the tests results. Twenty medical students from 3rd to 6th year were analyzed, with an average age of 22.8 (21-26) years. The average participation in the proposed activities was 10.4/13 (80%). The average of right answers on the first test was 8.1/17 (47.6%), and 3rd year students had lower grades (pperformance (pevaluation tests, suggesting that the league is a useful teaching instrument that can provide improved learning of anesthesiology. Participation in activities was connected with improved performance. Activities developed in leagues may have a positive role in students' academic education, more specifically in this article, in anesthesiology. Copyright © 2012 Elsevier Editora Ltda.

Una fuente de contaminación muy importante son los pesticidas, entre los cuales están los organofosforados, (OP, los que se utilizan, entre otros fines, para el control de ectoparásitos como la mosca en el ganado lechero, lo cual es una práctica común en nuestro medio. Subsiguiente al tratamiento de vacas lecheras con OP, estos productos pueden ser eliminados a través de la leche y residuos de OP ser encontrados en ella. Los pesticidas, entre ellos los OP como el fention, plantean un serio peligro para la salud, por lo tanto, son necesarios estudios que profundicen en el comportamiento de estos plaguicidas en los líquidos corporales de los animales especialmente en los de consumo humano como la leche, con el fin de conocer el riesgo real para la salud de los animales y del hombre. Aunque la medición de los residuos tóxicos y sus metabolitos se puede hacer en otros líquidos biológicos como la sangre y la orina, dadas las características especiales de consumo de leche por los humanos, es necesario cuantificar los residuos de plaguicidas en ella.

    Full Text Available En México, la población caprina se concentra en sistemas de producción extensivos, con hatos formados en mayoría por cabras que los productores llaman criollas, denominación ahora aceptada como locales. La alimentación de la cabra lechera en el sistema extensivo es a través del pastoreo, pero éste, por sí solo no puede satisfacer las necesidades nutricion ales de la cabra. Por tanto, si se quiere aumentar la producción de leche, es necesario complementar la alimentación de las cabras en pastoreo. Al respecto, en rumiantes en pastoreo que han sido complementados con un alimento integral se han reportado aume ntos en la producción de leche. Por lo tanto, el objetivo de estudio fue evaluar el efecto en la producción y composición de la leche de cabras locales en pastoreo complementadas con un alimento integral. Para ello, se realizaron dos experimentos. En el pr imero, se evaluó el efecto de cambiar de un sistema de pastoreo a uno estabulado, con el fin de desafiar a las cabras a que expresaran su potencial productivo al ofrecerles un alimento integral. En el segundo, se evaluó el efecto en producción de leche y c omponentes de la leche de cabras en pastoreo al complementarlas con diferentes niveles del alimento integral usado en el experimento 1. Los datos de producción de leche y composición química en leche de ambos experimentos fueron analizados utilizando un mo delo de medidas repetidas. Los datos de peso vivo y condición corporal final de las cabras, se analizaron como un diseño completamente al azar. Se realizó un análisis de costos parciales en ambos experimentos, con el fin de conocer la viabilidad económica de los tratamientos. En el experimento 1, la concentración de grasa en leche no se modificó (p > 0.05 por efecto de tratamientos, pero si aumentó (p ≤ 0.01 la producción de leche y la concentración (p ≤ 0.05 de proteína y lactosa en leche de cabras esta buladas comparadas con cabras en pastoreo.

  19. EVALUATING AUSTRALIAN FOOTBALL LEAGUE PLAYER CONTRIBUTIONS USING INTERACTIVE NETWORK SIMULATION

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available This paper focuses on the contribution of Australian Football League (AFL players to their team's on-field network by simulating player interactions within a chosen team list and estimating the net effect on final score margin. A Visual Basic computer program was written, firstly, to isolate the effective interactions between players from a particular team in all 2011 season matches and, secondly, to generate a symmetric interaction matrix for each match. Negative binomial distributions were fitted to each player pairing in the Geelong Football Club for the 2011 season, enabling an interactive match simulation model given the 22 chosen players. Dynamic player ratings were calculated from the simulated network using eigenvector centrality, a method that recognises and rewards interactions with more prominent players in the team network. The centrality ratings were recorded after every network simulation and then applied in final score margin predictions so that each player's match contribution-and, hence, an optimal team-could be estimated. The paper ultimately demonstrates that the presence of highly rated players, such as Geelong's Jimmy Bartel, provides the most utility within a simulated team network. It is anticipated that these findings will facilitate optimal AFL team selection and player substitutions, which are key areas of interest to coaches. Network simulations are also attractive for use within betting markets, specifically to provide information on the likelihood of a chosen AFL team list "covering the line".

    Rugby league is the main professional team sport played in Eastern Australia. It is also very popular at a junior and amateur level. However, injuries are common because of the amount of body contact that occurs and the amount of running that is required to participate in the game. Injuries to the lower limbs account for over 50% of all injuries. The most common specific injuries are ankle lateral ligament tears, knee medial collateral and anterior cruciate ligament tears, groin musculotendinous tears, hamstring and calf muscle tears, and quadriceps muscle contusions. Head injuries are common and consist of varying degrees of concussion as well as lacerations and facial fractures. Serious head injury is rare. Some of the more common upper limb injuries are to the acromioclavicular and glenohumeral joints. Accurate diagnosis of these common injuries using appropriate history, examination and investigations is critical in organising a treatment and rehabilitation plan that will return the player to competition as soon as possible. An understanding of the mechanism of injury is also important in order to develop preventative strategies.

    In this paper, we show a new technique to analyze families of rankings. In particular, we focus on sports rankings and, more precisely, on soccer leagues. We consider that two teams compete when they change their relative positions in consecutive rankings. This allows to define a graph by linking teams that compete. We show how to use some structural properties of this competitivity graph to measure to what extend the teams in a league compete. These structural properties are the mean degree, the mean strength, and the clustering coefficient. We give a generalization of the Kendall's correlation coefficient to more than two rankings. We also show how to make a dynamic analysis of a league and how to compare different leagues. We apply this technique to analyze the four major European soccer leagues: Bundesliga, Italian Lega, Spanish Liga, and Premier League. We compare our results with the classical analysis of sport ranking based on measures of competitive balance.

    Lingering neurologic injury after concussion may expose athletes to increased risk if return to play is premature. The authors explored whether on-field performance after concussion is a marker of lingering neurologic injury. Retrospective cohort study on 1882 skill-position players who played in the National Football League (NFL) during 2007-2010. Players with concussion based on the weekly injury report were compared with players with other head and neck injuries (controls) on measures of on-field performance using Football Outsiders' calculation of defense-adjusted yards above replacement (DYAR), a measure of a player's contribution controlling for game context. Changes in performance, relative to a player's baseline level of performance, were estimated before and after injury using fixed-effects models. The study included 140 concussed players and 57 controls. Players with concussion performed no better or worse than their baseline on return to play. However, a decline in DYAR relative to their prior performance was noted 2 wk and 1 wk before appearing on the injury report. Concussed players performed slightly better than controls in situations where they returned to play the same week as appearing on the injury report. On return, concussed NFL players performed at their baseline level of performance, suggesting that players have recovered from concussion. Decline in performance noted 2 wk and 1 wk before appearing on the injury report may suggest that concussion diagnosis was delayed or that concussion can be a multihit phenomenon. Athletic performance may be a novel tool for assessing concussion injury and recovery.

    Significant attention has been directed toward the immediate and long-term effects of sport-related concussions on athletes participating in contact sports, particularly football. The highest level of football, the National Football League (NFL), has received significant attention and criticism regarding player management and safety after mild traumatic brain injury (mTBI). Several review articles have reported data related to concussion in the NFL, but a succinct review and synthesis of data regarding NFL concussions is currently lacking. To (1) review systematically the published data regarding concussion in the NFL and assess limitations of the studies, (2) elucidate areas where further research is needed, and (3) identify methods to improve future investigations of concussion in the NFL. Systematic review of literature. English-language titles and abstracts published between 1900 and September 2014 were searched systematically across electronic databases, and a review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Peer-reviewed journal articles were included if they contained NFL concussion data with or without additional associated long-term effects. Reviews, editorials, letters to the editor, and comments were not included. Of the 344 records screened for review, 88 articles were assessed for eligibility. There were 31 studies that met the inclusion criteria and formed the basis of the evidence synthesis. Included in the current review were 8 case-control studies (Oxford Centre for Evidence-Based Medicine evidence level 3b), 6 descriptive epidemiological studies (level 4), 6 cross-sectional studies (level 4), 6 cohort studies (level 2b), and 5 case series (level 4). The study of concussions in the NFL has been limited by lack of recent empirical data, reliance on self-reported concussion history, and ascertainment bias of brains donated for autopsy studies.

    Full Text Available Pese a la existencia de varios estudios sobre diversos aspectos de los quesos de vaca y cabra, hay una escasa información sobre sus propiedades texturales. El estudio de las propiedades reológicas en los quesos es importante porque determina el cuerpo y textura característicos. La presente investigación se realizó con el fin de comparar el perfil de textura de los quesos frescos pasteurizados elaborados a partir de leche de cabra y de vaca y con contenidos de grasa de 30, 50 y 70%; los cuales fueron almacenados en refrigeración a 4°C y analizados los días 1, 6, 12, y 18 respectivamente. Los parámetros texturales de dureza, adhesividad, cohesividad, elasticidad, gomosidad y masticabilidad, se determinaron utilizando un texturómetro EZ-TEST SERIES S. Se concluye que los valores de dureza y adhesividad aumentaron durante el tiempo de almacenamiento, contrario a la elasticidad y cohesividad. Además, el aumento del contenido graso influye en el incremento de estos parámetros a excepción de la dureza. Así mismo, la gomosidad y masticabilidad varían con respecto a la dureza, cohesividad y elasticidad. Los quesos frescos de cabra presentaron mayor adhesividad, cohesividad y elasticidad, con respecto a los quesos frescos de vaca, en los cuales los valores de dureza fueron mayores.

    In 1913, the Anti-Saloon League of America declared its intention to pursue national prohibition. While it continued to adhere to its core principles of agitation, it expanded its communication efforts and entered a partnership with the Scientific Temperance Federation, a spin-off of the education arm of the Woman's Christian Temperance Union. The League's tactics were not necessarily new to the temperance movement -- or even to other reform movements of the time. What did set it apart was its single-minded focus on stopping the liquor traffic. Tracing through archival artifacts the League's communication strategies and tactics during 1913, then, this study contributes to a larger body of work that seeks to expand on the traditional model of public relations history.

    Highlights: • Optimal power flow. • Reducing electrical energy loss. • Saving electrical energy. • Optimal operation. - Abstract: A new efficient optimization method, called the League Championship Algorithm (LCA) is proposed in this paper for solving the optimal power flow problem. This method is inspired by the competition of sport teams in an artificial sport league for several weeks and over a number of seasons. The proposed method has been applied to the Algerian power system network for different objectives. Furthermore, in order to assess the effectiveness of the proposed LCA method the obtained results using this method have been compared to those obtained using other methods reported in the literature. The obtained results and the comparison with other techniques indicate that the league championship algorithm provides effective and high-quality solution when solving the optimal power flow problem

    2009-11-01

    As the nation and world grapple with looming crises in sectors such as energy, health care and the environment, it is critical that we keep today's youth interested in careers in science, technology, engineering and math (STEM). Studies indicate that many students lose interest in the sciences by ages 10-13, when they are in grades 4-8 in the U.S. educational system. Many of the interventions to counteract this trend focus on boosting interest in STEM in secondary schools and universities. However the case can be made that the greater need is actually earlier in the education of the child. How can we work with this age group in an exciting way that will promote the study of science? Student robotics competitions might be one effective answer. Programs are currently being run around the country and the world that engage young people in the study of science through robotic competition. Many of these programs rely on mentors to guide the students through the process, which in the most effective programs includes the study of physic concepts through engineering design. During this presentation we will discuss the options for participating in programs that help the students and teachers better understand the science, specifically the physics, which underlies robotics. In particular, we will focus on the international program called FIRST LEGO League (FLL), in which students ages 9-14 are challenged every year to construct a LEGO robot that can navigate and complete a course of theme-related missions. The FLL program is currently operating in almost every state in the U.S. and relies on recruiting qualified mentors and judges who want to impact young people's interest in STEM. Physics professionals can make a tremendous difference in the lives of these eager middle school students.

    There is current disagreement in the scientific literature about the relationship between playing football and suicide risk, particularly among professional players in the National Football League (NFL). While some research indicates players are at high risk of football-related concussions, which may lead to chronic traumatic encephalopathy and suicide, other research finds such a connection to be speculative and unsupported by methodologically sound research. To compare the suicide mortality of a cohort of NFL players to what would be expected in the general population of the United States. Cohort study; Level of evidence, 3. A cohort of 3439 NFL players with at least 5 credited playing seasons between 1959 and 1988 was assembled for statistical analysis. The vital status for this cohort was updated through 2013. Standardized mortality ratios (SMRs), the ratio of observed deaths to expected deaths, and 95% CIs were computed for the cohort; 95% CIs that excluded unity were considered statistically significant. For internal comparison purposes, standardized rate ratios were calculated to compare mortality results between players stratified into speed and nonspeed position types. Suicide among this cohort of professional football players was significantly less than would be expected in comparison with the United States population (SMR = 0.47; 95% CI, 0.24-0.82). There were no significant differences in suicide mortality between speed and nonspeed position players. There is no indication of elevated suicide risk in this cohort of professional football players with 5 or more credited seasons of play. Because of the unique nature of this cohort, these study results may not be applicable to professional football players who played fewer than 5 years or to college or high school players. © 2016 The Author(s).

    Objective Existing criteria for the classification of gout have suboptimal sensitivity and/or specificity, and were developed at a time when advanced imaging was not available. The current effort was undertaken to develop new classification criteria for gout. Methods An international group of investigators, supported by the American College of Rheumatology and the European League Against Rheumatism, conducted a systematic review of the literature on advanced imaging of gout, a diagnostic study in which the presence of monosodium urate monohydrate (MSU) crystals in synovial fluid or tophus was the gold standard, a ranking exercise of paper patient cases, and a multi-criterion decision analysis exercise. These data formed the basis for developing the classification criteria, which were tested in an independent data set. Results The entry criterion for the new classification criteria requires the occurrence of at least one episode of peripheral joint or bursal swelling, pain, or tenderness. The presence of MSU crystals in a symptomatic joint/bursa (ie, synovial fluid) or in a tophus is a sufficient criterion for classification of the subject as having gout, and does not require further scoring. The domains of the new classification criteria include clinical (pattern of joint/bursa involvement, characteristics and time course of symptomatic episodes), laboratory (serum urate, MSU-negative synovial fluid aspirate), and imaging (double-contour sign on ultrasound or urate on dual-energy CT, radiographic gout-related erosion). The sensitivity and specificity of the criteria are high (92% and 89%, respectively). Conclusions The new classification criteria, developed using a data-driven and decision-analytic approach, have excellent performance characteristics and incorporate current state-of-the-art evidence regarding gout.

    A combined estimate of injuries within a specific sport through pooled analysis provides more precise evidence and meaningful information about the sport, whilst controlling for between-study variation due to individual sub-cohort characteristics. The objective of this analysis was to review all published rugby league studies reporting injuries from match and training participation and report the pooled data estimates for rugby league concussion injury epidemiology. A systematic literature analysis of concussion in rugby league was performed on published studies from January 1990 to October 2015. Data were extracted and pooled from 25 studies that reported the number and incidence of concussions in rugby league match and training activities. Amateur rugby league players had the highest incidence of concussive injuries in match activities (19.1 per 1000 match hours) while semi-professional players had the highest incidence of concussive injuries in training activities (3.1 per 1000 training hours). This pooled analysis showed that, during match participation activities, amateur rugby league participants had a higher reported concussion injury rate than professional and semi-professional participants. Semi-professional participants had nearly a threefold greater concussion injury risk than amateur rugby league participants during match participation. They also had nearly a 600-fold greater concussion injury risk than professional rugby league participants during training participation.

  20. An Integrated Constraint Programming Approach to Scheduling Sports Leagues with Divisional and Round-robin Tournaments

    Energy Technology Data Exchange (ETDEWEB)

    Carlsson, Mats; Johansson, Mikael; Larson, Jeffrey

    2014-01-01

    Previous approaches for scheduling a league with round-robin and divisional tournaments involved decomposing the problem into easier subproblems. This approach, used to schedule the top Swedish handball league Elitserien, reduces the problem complexity but can result in suboptimal schedules. This paper presents an integrated constraint programming model that allows to perform the scheduling in a single step. Particular attention is given to identifying implied and symmetry-breaking constraints that reduce the computational complexity significantly. The experimental evaluation of the integrated approach takes considerably less computational effort than the previous approach.

    Full Text Available El suero de leche se ha constituido en el principal desecho de la industria láctea, a pesar de los constantes esfuerzos por aprovecharlo. El presente trabajo tuvo por objeto estudiar la obtención de ácido cítrico por fermentación sumergida con hongos del género Aspergillus, utilizando lactosuero en calidad de sustrato con miras a su aprovechamiento y a la reducción del impacto ambiental que causan los vertimientos de este subproducto en los cursos de agua. Se utilizaron las siguientes cepas: A. carbonarius NRRL 368, A. carbonarius NRRL 67 y A. niger NRRL 3. Fue seleccionado el mejor medio de adaptación para la propagación del inóculo. El diseño experimental planteado para evaluar la biosíntesis de ácido cítrico a partir de suero de leche modificado mediante diferentes tratamientos, dio como resultado que las dos cepas de A. carbonarius no presentaran diferencias significativas en la formación del ácido, mientras A. niger NRRL 3 alcanzó mayores concentraciones cuando se utilizó suero de leche desproteinizado, evaporado y con lactosa hidrolizada con f>-galactosidasa. A. carbonarius arrojó concentraciones promedio de ácido cítrico mayores que las encontradas para A. niger, lo que sugiere la necesidad de profundizar en su estudio como productor potencial. Se obtuvo la cinética de crecimiento celular, consumo de sustrato y formación del ácido en un biorreactor de tanque agitado con aireación de 3 L para el caso de A. niger, la cual fue simulada mediante modelos matemáticos no estructurados.

    To determine the normal profiles for hip strength and range of motion (ROM) in a professional football league in Qatar, and examine the effect of leg dominance, age, past history of injury, and ethnicity on these profiles. Cross-sectional cohort study. Participants included 394 asymptomatic, male professional football players, aged 18-40 years. Strength was measured using a hand held dynamometer with an eccentric test in side-lying for hip adduction and abduction, and the squeeze test in supine with 45° hip flexion. Range of motion measures included: hip internal and external rotation in 90° flexion, hip IR in prone, bent knee fall out and hip abduction in side-lying. Demographic information was collected and the effect on the profiles was analysed using linear mixed models with repeated measures. Strength values (mean±SD) were: adduction=3.0±0.6Nm/kg, abduction=2.6±0.4Nm/kg, adduction/abduction ratio=1.2±0.2, Squeeze test=3.6±0.8N/kg. Range of motion values: internal rotation in flexion=32±8°, external rotation=38±8°, internal rotation in prone=38±8°, bent knee fall out=13±4.4cm, abduction in side-lying=50±7.3°. Leg dominance had no clinically relevant effect on these profiles. Multivariate analysis demonstrated that age had a minor influence on squeeze strength (-0.03N/kg/year), external rotation (-0.30°/year) and abduction range (-0.19°/year) but past history of injury, and ethnicity did not. Normal values are documented for hip strength and range of motion that can be used as reference profiles in the clinical assessment, screening, and management of professional football players. Leg dominance, recent past injury history and ethnicity do not need to be accounted for when using these profiles for comparison purposes. Copyright © 2016 Sports Medicine Australia.

By Quick Scan measures, emulsions formulated with soy milk (5 and 10 %, variable proportion and composition of lipid phase and absence or presence of xhantan gum, more stable formulations were determined. Creaming was the main mechanism of destabilization of the emulsions. Those formulated with more concentrated soy milk, greater content of lipid phase and presence of xhantan gum were more stable. The stability increase of emulsions with a higher content of oil was attributed to the increase of viscosity instead of the droplet size. The content of milk fat in lipid phase had a low influence on droplet size but didn't show changes in droplet distribution and emulsion stability. Consistency increase due to stirring was favoured in emulsions of 40-50 % of lipid phase (30-50 % of milk fat.Se evaluó la obtención de cremas líquidas estables compuestas por leche de soja en polvo, aceite de girasol refinado y grasa láctea. Por medidas de estabilidad (QuickScan de emulsiones O/W con 5 % y 10 % de leche de soja, diferente cantidad y composición de fase lipídica y ausencia o presencia de goma xántica, se determinaron las formulaciones más estables. En las emulsiones inestables, el proceso predominante de desestabilización fue la separación gravitacional. Las emulsiones más estables fueron las preparadas con goma xántica, 10 % de leche de soja y mayor contenido de fase lipídica. El aumento de la estabilidad en las emulsiones con mayor contenido de aceite no se atribuyó al tamaño de gota sino a un aumento de la viscosidad. La variación del contenido de grasa láctea (a igual concentración de leche de soja y proporción de fase lipídica influyó levemente en el tamaño de gota pero no en su distribución ni en la estabilidad. De las emulsiones preparadas, sólo aquellas con un alto porcentaje de fase lipídica (40

    Full Text Available Black lechwe (Kobus leche smithemani is a semi-aquatic medium sized antelope currently enlisted on the IUCN red list of endangered species and is only endemic to the Bangweulu basin of Zambia. Its population has significantly decreased due to floods that took place during the period 1930-1940 from over 250 000-15 000 leading the Zambian government to gazette all habitats of Black lechwe into state protected areas, and to establish urgent management strategies needed to save the remaining population from extinction. Using retrospective data, our findings show that the population has increased from 15 000 animals in 1954 to 55 632 in 2009. The current population is estimated at 34.77% (55 632/160 000 of the carrying capacity of the Bangweulu basin. Although the Black lechwe is one of the 42 species offered for consumptive utilization by the Zambia Wildlife Authority (ZAWA, only 0.12% and 0.08% of the current stock was offered for safari and resident hunting annually for the period 2005-2009, respectively. Annual quota utilization were estimated at 67% (n=37 and 81% (n=37 for safari and resident hunting, respectively. Hence, overall income obtained from utilization of Black lechwe is very low accounting for only 2.1% of the total revenue earned from wildlife utilization. Although the current population trend is showing a unit increase of 639 animals per year, it is still far below levels ideal for the lucrative utilization. In this study, we demonstrate that adverse ecological changes on wildlife species, can lead to their vulnerability and danger of extinction, and that their recovery to full carrying capacity may demand a considerable amount of time

    This study establishes the sleep behaviour of players and staff during the pre- and competitive seasons of elite rugby league. For seven days during both the pre- and competitive seasons, seven rugby league players and nine full-time staff from one professional Australian rugby league club had their sleep monitored via wrist actigraphy and self-report sleep diaries. Two-way repeated measures analysis of variance determined differences between the pre- and competitive season in players and staff, with effect sizes (ES) used to interpret the practical magnitude of differences. Findings show an earlier bed time and wake time for players (-34 min, ES = 1.5; ±0.5 and -39 min, 2.1; ±0.5 respectively) and staff (-29 min, ES = 0.8; ±0.3 and -35 min, ES = 1.7; ±0.4 respectively) during pre-season when compared to the competitive season. Despite this, no differences were seen when considering the amount of time in bed, sleep duration or sleep efficiency obtained between the pre- and competitive seasons. Our results suggest that early morning training sessions scheduled during pre-season advances wake time in elite rugby league. However, both players and staff can aim to avoid reductions in sleep duration and sleep efficiency with subsequent adjustment of night time sleep patterns. This may be particularly pertinent for staff, who wake earlier than players during both the pre- and competitive seasons.

    Full Text Available Strength imbalances between the hamstrings and quadriceps are an essential predictor for hamstring strain in soccer. The study aimed to investigate and compare the muscle strength imbalances of professional soccer players of different performance levels. One hundred and fifty nine senior male professional soccer players from first (n = 75 and second league (n = 84 Portuguese clubs participated in this study. Muscle strength was evaluated with a REV9000 isokinetic dynamometer. Maximal peak torque data were used to calculate quadriceps and hamstrings strength during concentric and eccentric actions, bilateral asymmetry, conventional strength ratios and dynamic control ratios. Second league athletes produced slightly lower conventional strength ratios in the right and left legs (ES = 0.22, p = 0.17 and ES = 0.36, p = 0.023, respectively compared to the first league athletes. No significant differences were found in dynamic control ratios or in bilateral asymmetry among first and second league athletes. These findings do not show a clear link between the competitive level and injury risk in soccer players. However, some of the differences found, particularly in conventional strength ratios, highlight the importance of performing off-season and pre-season strength assessments to prescribe and adjust individual strength training programs among professional soccer players.

    Full Text Available The basic goal of this study was to analysis of the results of the 30-m running speed test in soccer players in third soccer leagues. The study examined the group of randomly selected seventy athletes from two soccer teams from the Ekstraklasa league, two teams from the first league and two teams from the second leagues were randomized into the study group. All the measurements were performed in indoor arenas. The temperature in the arenas ranged from 22 to 24 C. Measurements were recorded in the morning (between 10:00 am and 12:00 am. The Running Speed Test was used in the study to diagnose speed potential in the athletes. The running speed was measured by means of a set of photocells located at 0m, 5m, 20m, 30m. The results obtained demonstrated that the elite-level matches are more dynamic since the players show higher values of speed parameters. Apart from starting speed, the results obtained for the distance of 5 m provide information for coaches concerning their work on special strength. The speed is indicated by the results obtained for 20 and 30 m distances, whereas flying measurements between 5/20m and 20/30m reflect inherited speed aptitudes.

    To compare mechanical properties of overground sprint running in elite rugby union and rugby league athletes. Thirty elite rugby code (15 rugby union and 15 rugby league) athletes participated in this cross-sectional analysis. Radar was used to measure maximal overground sprint performance over 20 or 30 m (forwards and backs, respectively). In addition to time at 2, 5, 10, 20, and 30 m, velocity-time signals were analyzed to derive external horizontal force-velocity relationships with a recently validated method. From this relationship, the maximal theoretical velocity, external relative and absolute horizontal force, horizontal power, and optimal horizontal force for peak power production were determined. While differences in maximal velocity were unclear between codes, rugby union backs produced moderately faster split times, with the most substantial differences occurring at 2 and 5 m (ES 0.95 and 0.86, respectively). In addition, rugby union backs produced moderately larger relative horizontal force, optimal force, and peak power capabilities than rugby league backs (ES 0.73-0.77). Rugby union forwards had a higher absolute force (ES 0.77) despite having ~12% more body weight than rugby league forwards. In this elite sample, rugby union athletes typically displayed greater short-distance sprint performance, which may be linked to an ability to generate high levels of horizontal force and power. The acceleration characteristics presented in this study could be a result of the individual movement and positional demands of each code.

    Rugby league coaches adopt replacement strategies for their interchange players to maximize running intensity; however, it is important to understand the factors that may influence match performance. To assess the independent factors affecting running intensity sustained by interchange players during professional rugby league. Global positioning system (GPS) data were collected from all interchanged players (starters and nonstarters) in a professional rugby league squad across 24 matches of a National Rugby League season. A multilevel mixed-model approach was employed to establish the effect of various technical (attacking and defensive involvements), temporal (bout duration, time in possession, etc), and situational (season phase, recovery cycle, etc) factors on the relative distance covered and average metabolic power (P met ) during competition. Significant effects were standardized using correlation coefficients, and the likelihood of the effect was described using magnitude-based inferences. Superior intermittent running ability resulted in very likely large increases in both relative distance and P met . As the length of a bout increased, both measures of running intensity exhibited a small decrease. There were at least likely small increases in running intensity for matches played after short recovery cycles and against strong opposition. During a bout, the number of collision-based involvements increased running intensity, whereas time in possession and ball time out of play decreased demands. These data demonstrate a complex interaction of individual- and match-based factors that require consideration when developing interchange strategies, and the manipulation of training loads during shorter recovery periods and against stronger opponents may be beneficial.

    Full Text Available Background. Rugby league is a physically demanding team sport and the National Rugby League is the highest-level competition of rugby league in Australia. Frequent tackles and collisions between players result in a high incidence of injury to players. Concussion injuries have been the source of much debate, with reporting varying greatly depending on the definition used. Method. Injury records of 239 players from one professional National Rugby League were analysed during a continuous period of 15 years, with particular interest in the incidence and recurrence of concussions and the change in incidence over time. Result. A total of 191 concussions were recorded, affecting 90 players. The incidence of concussion injuries was found to be 28.33 per 1000 player match hours, with an increase over time (P=0.0217. Multiple concussions were recorded for 51 players. Conclusion. A statistically significant increase in the incidence of concussion injuries was found, without a concurrent increase in the number of head injuries or total injuries. New rules which mandate removal of players from the field may be beneficial for protection of players on the long term, although they risk being counterproductive, if they make players less likely to report their symptoms during matches.

    Full Text Available Home advantage was defined as the fact that home teams win more than the 50% of their matches (Courneya & Carron, 1992. The aim of this work was to investigate the home advantage in the ACB league and identify the game-related statistics which best discriminate home and away teams. The data were obtained from the Spanish Basketball Association for the period 2007-2008 ACB league (n= 306. Game related statistics were normalized to 100 ball possessions. In order to compare game related statistics in home and away teams, a discriminative analysis was employed. This analysis identifies the game related statistics that best discriminate between home and away teams. The function obtained was interpreted with the structural canonical coefficients (SC, with values higher than |.30|. In the 2007-2008 ACB league, the home teams won the 55.22% (n=169 of the games. The analysis identifying the two-point field goals made, blocks made, dunks, the defensive rebounds and the assists as common to the mean vectors that discriminate home teams in all games. Blocks received contribute to discriminate away teams in ACB league. These results could be used by the psychologist who works with the team. They must design specific programs to decrease anxiety levels, and to improve motivation and concentration levels in basketball players before a competition.

    Children and adolescents who play rugby are at increased risk of concussion and its effects. Competitive rugby union and rugby league feature as major sports in the school sport curriculum in the UK. There is a need for a thorough understanding of the epidemiology of concussion in youth rugby, the mechanisms involved in injuries and predisposing risk factors. The publication databases Pubmed, Embase and SportDISCUS were searched in April 2014 for primary research studies of child and adolescent rugby union and rugby league (under 20 years) in English language with data on concussion injuries. The review was conducted within a larger all injury systematic review on rugby union and rugby league where key words used in the search included rugby, injury and concussion with child, adolescent, paediatric and youth. There were 25 studies retrieved with data on child or adolescent rugby and concussion, 20 were on rugby union, three on rugby league and in two the code of rugby was unspecified. There was significant heterogeneity in the definitions of injuries and of concussion. The incidence of child and adolescent match concussion ranged from 0.2 to 6.9 concussions per 1000 player-hours for rugby union and was 4.6 and 14.7 concussions per 1000 player-hours for rugby league, equivalent to a probability of between 0.3% and 11.4% for rugby union and of 7.7% and 22.7% for rugby league. There is a significant risk of concussion in children and adolescents playing rugby union and rugby league evident from the studies included in this systematic review. There is a need for reliable data through routine monitoring and reporting in schools and clubs and in hospital emergency departments in order to inform prevention. Concussion protocols should be implemented and tested. Published by the BMJ Publishing Group Limited.

    Full Text Available Today the government ownership of the professional football clubs is absolutely illogical view point. Most of sports clubs are conducted by private sector using different models of ownership all over the world. In Iran, government credits benefit was main reason that the professional sport was firstly developed by government firms and organizations. Therefore, the sports team ownership is without the professionalization standards. The present comparative study was to examine the different football club ownership structures of the top leagues and the current condition of Iran football pro league ownership and then present a suitable ownership structure of Iran football clubs to leave behind the government club ownership. Among the initial 120 scientific texts, the thirty two cases including papers, books and reports were found relevant to this study. We studied the ownership prominence and several football club models of ownership focused on stock listing model of ownership, private investor model of ownership, supporter trust model of ownership and Japan partnership model of ownership; theoretical concepts, empirical studies, main findings, strengths and weaknesses were covered in analysis procedure. According to various models of ownership in leagues and the models’ productivity in football clubs, each model of ownership considering national environmental, economic, social conditions has strengths and weaknesses. So, we cannot present a definite model of ownership for Iran football pro league clubs due to different micro-environments of Iran clubs. We need a big planning to provide a supporter-investor mixed model of ownership to Iranian clubs. Considering strengths and weaknesses in the models of ownership as well as the micro and macro environment of Iran football clubs, German model and Japan partnership model are offered as suitable ones to probable new model of ownership in Iran pro league clubs. Consequently, more studies are required

    Acute complete ruptures of the proximal adductor longus tendon are rare but challenging injuries to treat. The limited literature supports operative treatment, but data from management of chronic groin pain in athletes indicate that anatomical attachment of the tendon to the pubis may not be required for high-level function. Nonoperative management of complete adductor rupture can provide equal results to surgical repair in terms of return to play in the National Football League. Case series; Level of evidence, 4. Using the National Football League Injury Surveillance System, adductor tendon ruptures documented by magnetic resonance imaging were identified in 19 National Football League players from 1992 to 2004. The team physician for each respective player completed a survey with information about history, physical examination, magnetic resonance imaging findings, treatment, and outcomes. Statistics were analyzed with a Student unpaired t test. Fourteen players were treated nonoperatively, and 5 players were treated with surgical repair using suture anchors. In both groups, all players eventually returned to play in the National Football League. Mean time for return to play was 6.1 +/- 3.1 weeks (range, 3-12 weeks) for the nonoperative group and 12.0 +/- 2.5 weeks (range, 10-16 weeks) for the operative group (P = .001). One player in the operative group suffered the complication of a draining wound and heterotopic ossification. Players represented a variety of positions, and 12 of 19 (63%) had experienced prior symptoms or events. Nonoperative treatment of proximal adductor tendon rupture results in a statistically significantly faster return to play than does operative treatment in athletes competing in the National Football League and avoids the risks associated with surgery while providing an equal likelihood of return to play at the professional level.

    In 1905, a group of eminent Greek physicians led by Professor of Hygiene and Microbiology Constantinos Savvas and the pediatrician Dr. Ioannis Kardamatis founded the Greek Anti-Malaria League. The League assumed a role that the State would not, and for the next 25 years organized the country's anti-malaria campaign. During its first steps, the Greek Anti-Malaria League adopted the principles of Professor Angelo Celli's Italian Anti-Malaria League. The League's accomplishments include a decrease in malarial prevalence, due to mass treatment with quinine, new legislation ensuring the provision of quinine, State monopoly and the collection of epidemiologic data. However, defeat in the Greek-Turkish War (1922) and the massive influx of one million Greek refugees that ensued, led to a change in malarial epidemiology. In 1928, following a visit to Italy, the Greek League adopted the organization and knowledge of the Italian Malaria Schools in Rome and in Nettuno, and this experience served as the basis of their proposal to the State for the development of the anti-malaria services infrastructure. The State adopted many of Professor Savvas' proposals and modified his plan according to Greek needs. The League's experience, accumulated during its 25 years of struggle against malaria, was its legacy to the campaigns that eventually accomplished the eradication of malaria from Greece after World War II.

    Watenpaugh, Keith David

    2010-01-01

    The essay centers of the efforts by the League of Nations to rescue women and children survivors of the 1915 Armenian Genocide. This rescue -- a seemingly unambiguous good -- was at once a constitutive act in drawing the boundaries of the international community, a key moment in the definition of humanitarianism, and a site of resistance to the colonial presence in the post-Ottoman Eastern Mediterranean. Drawing from a wide range of source materials in a number of languages, including Turkish, Armenian, and Arabic, the essay brings the intellectual and social context of humanitarianism in initiating societies together with the lived experience of humanitarianism in the places where the act took form. In so doing, it draws our attention to the proper place of the Eastern mediterranean, and its women and children, in the global history of humanitarianism. The prevailing narrative of the history of human rights places much of its emphasis on the post-World War II era, the international reaction to the Holocaust, and the founding of the United Nations. yet contemporary human rights thinking also took place within practices of humanitarianism in the interwar period, and is necessarily inseparable from the histories of refugees, colonialism, and the non-West.

    To examine the effects of 24-h travel west across 11 time zones on subjective jet-lag and wellness responses together with self-reported sleep and upper respiratory symptoms in 18 professional rugby league players. Measures were obtained 1 or 2 d before (pretravel) and 2, 6, and 8 d after travel (post-2, post-6, and post-8) from Australia to the United Kingdom (UK) for the 2015 World Club Series. Compared with pretravel, subjective jet-lag remained significantly elevated on post-8 (3.1 ± 2.3, P 0.90), although it was greatest on post-2 (4.1 ± 1.4). Self-reported sleep-onset times were significantly earlier on post-2 than at all other time points (P 0.90), and large effect sizes suggested that wake times were earlier on post-2 than on post-6 and post-8 (d > 0.90). Although significantly more upper respiratory symptoms were reported on post-6 than at pretravel (P .05, d sleep responses, along with upper respiratory symptoms, in professional rugby league players. Of note, the increase in self-reported upper respiratory symptoms is a reminder that the demands of long-haul travel may be an additional concern in jet-lag for traveling athletes. However, due to the lack of sport-specific performance measures, it is still unclear whether international travel interferes with training to the extent that subsequent competition performance is impaired.

    Full Text Available Black lechwe (Kobus leche smithemani is a semi-aquatic medium sized antelope currently enlisted on the IUCN red list of endangered species and is only endemic to the Bangweulu basin of Zambia. Its population has significantly decreased due to floods that took place during the period 1930-1940 from over 250 000-15 000 leading the Zambian government to gazette all habitats of Black lechwe into state protected areas, and to establish urgent management strategies needed to save the remaining population from extinction. Using retrospective data, our findings show that the population has increased from 15 000 animals in 1954 to 55 632 in 2009. The current population is estimated at 34.77% (55 632/160 000 of the carrying capacity of the Bangweulu basin. Although the Black lechwe is one of the 42 species offered for consumptive utilization by the Zambia Wildlife Authority (ZAWA, only 0.12% and 0.08% of the current stock was offered for safari and resident hunting annually for the period 2005-2009, respectively. Annual quota utilization were estimated at 67% (n=37 and 81% (n=37 for safari and resident hunting, respectively. Hence, overall income obtained from utilization of Black lechwe is very low accounting for only 2.1% of the total revenue earned from wildlife utilization. Although the current population trend is showing a unit increase of 639 animals per year, it is still far below levels ideal for the lucrative utilization. In this study, we demonstrate that adverse ecological changes on wildlife species, can lead to their vulnerability and danger of extinction, and that their recovery to full carrying capacity may demand a considerable amount of timeEl lechwe negro (Kobus leche smithemani es un antílope semi-acuático de tamaño medio que en la actualidad se encuentra en la lista roja de la UICN de especies en peligro de extinción y sólo es endémica de la cuenca del Bangweulu de Zambia.

    The aim of this review was to determine prevalence of dental caries in primary and permanent teeth in the 2-20-year-old population of the Arab league. A literature search was performed on Pubmed, Summon and Google Scholar using the key words 'Dental caries', 'dmft' and 'DMFT'. A total of 293 articles were found, of which 35 passed our inclusion criteria and were included in analysis. Tables were made separately for primary and permanent teeth; the age group for primary teeth was 2-12 years and for permanent teeth 6-20 years. A meta-analysis was run by using data extracted from the studies included. Heterogeneity was tested by forest plot and chi-square test, and considerable heterogeneity was found. Mean decayed, missing and filled teeth (dmft) was 4.341 (95% CI 3.714, 4.969) and in permanent teeth (DMFT) was 2.469 (95% CI 2.019, 2.919) from a random effect model. Publication bias diagnostics suggested missing of four studies of primary teeth caries data and eight studies of permanent teeth caries data to obtain symmetry in the funnel plot. The incidence of caries in primary teeth was found to be high compared with caries in permanent teeth in the Arab League. This study does not provide a comprehensive picture of caries prevalence in the Arab League because in many of these countries only a few studies were performed. Therefore, these data cannot provide a complete picture of the prevalence of caries in those countries. Additional studies are needed to better evaluate the prevalence of caries in children and young adults in Arab League countries. © 2014 FDI World Dental Federation.

    Repeat-high-intensity efforts (RHIEs) have recently been shown to occur at critical periods of rugby league matches. To examine the effect that caffeine has on RHIE performance in rugby league players. Using a double-blind, placebo-controlled, crossover design, 11 semiprofessional rugby league players (age 19.0 ± 0.5 y, body mass 87.4 ± 12.9 kg, height 178.9 ± 2.6 cm) completed 2 experimental trials that involved completing an RHIE test after either caffeine (300 mg caffeine) or placebo (vitamin H) ingestion. Each trial consisted of 3 sets of 20-m sprints interspersed with bouts of tackling. During the RHIE test, 20-m-sprint time, heart rate (HR), rating of perceived exertion (RPE), and blood lactate were measured. Total time to complete the nine 20-m sprints during the caffeine condition was 1.0% faster (28.46 ± 1.4 s) than during the placebo condition (28.77 ± 1.7 s) (ES = 0.18, 90%CI -0.7 to 0.1 s). This resulted in a very likely chance of caffeine being of benefit to RHIE performance (99% likely to be beneficial). These improvements were more pronounced in the early stages of the test, with a 1.3%, 1.0%, and 0.9% improvement in sprint performance during sets 1, 2, and 3 respectively. There was no significant difference in RPE across the 3 sets (P = .47, 0.48, 1.00) or mean HR (P = .36), maximal HR (P = .74), or blood lactate (P = .50) between treatment conditions. Preexercise ingestion of 300 mg caffeine produced practically meaningful improvements in RHIE performance in rugby league players.

    Anterior cruciate ligament (ACL) injuries can have negative consequences on the careers of National Football League (NFL) players, however no study has ever analyzed the financial impact of these injuries in this population. To quantify the impact of ACL injuries on salary and career length in NFL athletes. Cohort study; Level of evidence, 3. Any player in the NFL suffering an ACL injury from 2010 to 2013 was identified using a comprehensive online search. A database of NFL player salaries was used to conduct a matched cohort analysis comparing ACL-injured players with the rest of the NFL. The main outcomes were the percentage of players remaining in the NFL and mean salary at 1, 2, 3, and 4 years after injury. Cohorts were subdivided based on initial salary: group A, $2,000,000. Mean cumulative earnings were calculated by multiplying the percentage of players remaining in the league by their mean salaries and compounding this each season. NFL athletes suffered 219 ACL injuries from 2010 to 2013. The 7504 other player seasons in the NFL during this time were used as controls. Significantly fewer ACL-injured players than controls remained in the NFL at each time point (P negatively affected. This demonstrates the degree of negative impact these injuries have on the careers of NFL players. It also indicates that a player's standing within the league before injury strongly influences how much an ACL injury will affect his career.

    To date, empirical reports of an association between motivation and athlete burnout have been exclusively based on cross-sectional research. Conclusions regarding the nature of the relationship between motivation and burnout are limited because they do not provide longitudinal information. To examine the relationship between burnout and motivation across a 12-wk league tournament (pretournament, midtournament, and end of tournament). Data were collected on using the Athlete Burnout Questionnaire and Sport Motivation Scale from 102 adult professional male rugby players at three different times during a 12-wk league tournament. Linear mixed modeling was used to explore hypothesized relationships between individual key characteristics of burnout and factors/covariates across time. Within the models, amotivation, the least self-determined type of motivation, had a large positive association with key characteristics of burnout. Self-determined forms of motivation (i.e., intrinsic motivation) exhibited significant negative associations with burnout. Extrinsic motivation, proposed to exist between intrinsic and amotivation on the self-determination continuum, was negatively associated with sport devaluation and reduced accomplishment as well as positively associated with physical and emotional exhaustion. Other factors related to burnout within the analysis included time (pretournament, in tournament, and end of tournament), team membership, number of injuries, years of national domestic league experience, and win/loss history. Overall, the results reflect the burnout experience may vary over time and support the potential utility of a self-determination theory explanation of burnout.

    The purpose of this study was to evaluate (a) whether there were differences in sprint times at 5, 10, 20, 30, and 40 m between rugby union and rugby league players, (b) determine the reliability and usefulness of linear sprint testing in adolescent rugby players. Data were collected on 28 rugby union and league academy players over 2 testing sessions, with 3-day rest between sessions. Rugby league players were faster at 5 m than rugby union players, with further difference unclear. Sprint time at 10, 20, 30, and 40 m was all reliable (coefficient of variation [CV] = 3.1, 1.8, 2.0, and 1.3%) but greater than the smallest worthwhile change (SWC [0.2 × between-subject SD]), rating the test as marginal for usefulness. Although the test was incapable of detecting the SWC, we recommend that practitioners and researchers use Hopkins' proposed method; whereby plotting the change score of the individual at each split (±typical error [TE] expressed as a CV) against the SWC and visually inspecting whether the TE crosses into the SWC are capable of identifying whether a change is both real (greater than the noise of the test, i.e., >TE) and of practical significance (>SWC). Researchers and practitioners can use the TE and SWC from this study to assess changes in performance of adolescent rugby players when using single beam timing gates.

    This study estimated the expected point value for starting possessions in different field locations during rugby league match-play and calculated the mean expected points for each subsequent play during the possession. It also examined the origin of tries scored according to the method of gaining possession. Play-by-play data were taken from all 768 regular-season National Rugby League (NRL) matches during 2010-2013. A probabilistic model estimated the expected point outcome based on the net difference in points scored by a team in possession in a given situation. An iterative method was used to approximate the value of each situation based on actual scoring outcomes. Possessions commencing close to the opposition's goal-line had the highest expected point equity, which decreased as the location of the possession moved towards the team's own goal-line. Possessions following an opposition error, penalty or goal-line dropout had the highest likelihood of a try being scored on the set subsequent to their occurrence. In contrast, possessions that follow an opposition completed set or a restart were least likely to result in a try. The expected point values framework from our model has applications for informing playing strategy and assessing individual and team performance in professional rugby league.

These are (in alphabetical order the premier leagues in the Austrian, Czech, Hungarian, and Ukrainian soccer/football divisions. Static balance shows how teams in the league tables of each year differ from each another. It is determined by a calculation of determinant divergences in the percentages of winnings. The results of this work provide graphic illustrations of the development of the competitive balance in the aforementioned contests over the latest forty-two years. They identify the development trend of this phenomenon. Of the contests studied, it is the Czech premier league which used to show the highest static balance.

    Super League (SL) and Championship (RLC) rugby league players will compete against each other in 2015 and beyond. To identify possible discrepancies, this study compared the anthropometric profile and body composition of current SL (full-time professional) and RLC (part-time semi-professional) players using dual-energy X-ray absorptiometry (DXA). A cross-sectional design involved DXA scans on 67 SL (n=29 backs, n=38 forwards) and 46 RLC (n=20 backs, n=26 forwards) players during preseason. A one-way ANOVA was used to compare age, stature, body mass, soft tissue fat percentage, bone mineral content (BMC), total and regional (i.e., arms, legs and trunk) fat and lean mass between SL forwards, SL backs, RLC forwards and RLC backs. No significant differences in age, stature or body mass were observed. SL forwards and backs had relatively less soft tissue fat (17.5 ± 3.7 and 14.8 ± 3.6 vs. 21.4 ± 4.3 and 20.8 ± 3.8%), greater BMC (4,528 ± 443 and 4,230 ± 447 vs. 4,302 ± 393 and 3,971 ± 280 g), greater trunk lean mass (37.3 ± 3.0 and 35.3 ± 3.8 vs. 34.9 ± 32.3 and 32.3 ± 2.6 kg) and less trunk fat mass (8.5 ± 2.7 and 6.2 ± 2.1 vs. 10.7 ± 2.8 and 9.5 ± 2.9 kg) than RLC forwards and backs. Observed differences may reflect selection based on favourable physical attributes, or training adaptations. To reduce this discrepancy, some RLC players should reduce fat mass and increase lean mass, which may be of benefit for the 2015 season and beyond.

El conocimiento de la materia prima repercute en la toma de decisiones del productor y la industria.  El objetivo de este estudio fue analizar la influencia de la caseína, su perfil y otros componentes de la leche en el rendimiento del queso Dambo, producido a escala piloto e industrial, con leches provenientes del Litoral Noroeste Uruguayo. A escala piloto se utilizaron condiciones de: alta caseína y bajo RCS, alta caseína y alto RCS, baja caseína y bajo RCS y baja caseína y alto RCS. En escala industrial se compararon los quesos de alta caseína con el promedio de planta. Se estudiaron dos estaciones. Se encontró que el queso Dambo elaborado con alta caseína (>2,6g/100g y bajo RCS (<200.000cel/mil tuvo un aumento de rendimiento del 10% respecto al de baja  caseína  (<2,41g/100g y alto RCS (>500.000cel/mil, ocasionado por mayor  recuperación de materia grasa en el queso. A escala industrial se obtuvo un aumento del 9% utilizando alta caseína en leche. Asimismo, existe una influencia positiva de la ĸ- CN y ß-CN en el rendimiento quesero, con una asociación entre α-CN y recuperación de materia grasa.

    Full Text Available Introduction. Each change in the rules of a sport affects the way it is performed. Therefore, changes in regulations require that new training models be developed. The aim of the study was to determine whether FIBA’s introduction of new regulations in the 2010/2011 season pertaining to the dimensions of certain parts of the playing area, which changed the conditions under which the game was played, impacted the offensive actions of the top three teams in the Polish Basketball League. Material and methods. The study analysed qualitative data describing the offences (n = 16,694 performed during 200 matches of the Polish Basketball League, that is the highest-level men’s professional basketball league in Poland, during two periods: the 2009/2010 season (110 matches; n = 9,343 offences, before the regulations were modified, and the 2010/2011 season (90 matches; n = 7,351 offences, after they were changed. The research involved the players of three teams who received the gold, silver, and bronze medals in the final standings of the Polish National Championship in the 2009/2010 season. Results. The study found a statistically significant (p < 0.001 decrease in the overall number of tactical offensive actions of 3.84% and a significant (p < 0.05 5% decrease in the mean number of points scored. A significant (p < 0.05 decrease in half-court offences, amounting to almost 2% was also observed. This offensive system was characterised by a minor shift toward individual offences with the back to the basket and pick-and-roll offences; these changes, however, did not cause an increase in the level of effectiveness. Conclusions. The direction of the changes observed have been determined, which consisted in a reduction in the overall number of offensive actions and a shift in the place where they were completed, from the three-point area in particular, to the two-point area.

    Cohort study. To determine the effect of cervical spine pathology on athletes entering the National Football League. The association of symptomatic cervical spine pathology with American football athletes has been described; however, it is unknown how preexisting cervical spine pathology affects career performance of a National Football League player. The medical evaluations and imaging reports of American football athletes from 2003 to 2011 during the combine were evaluated. Athletes with a cervical spine diagnosis were matched to controls and career statistics were compiled. Of a total of 2965 evaluated athletes, 143 players met the inclusion criteria. Athletes who attended the National Football League combine without a cervical spine diagnosis were more likely to be drafted than those with a diagnosis (P = 0.001). Players with a cervical spine diagnosis had a decreased total games played (P = 0.01). There was no difference in the number of games started (P = 0.08) or performance score (P = 0.38). In 10 athletes with a sagittal canal diameter of less than 10 mm, there was no difference in years, games played, games started, or performance score (P > 0.24). No neurological injury occurred during their careers. In 7 players who were drafted with a history of cervical spine surgery (4 anterior cervical discectomy and fusion, 2 foraminotomy, and 1 suboccipital craniectomy with a C1 laminectomy), there was no difference in career longevity or performance when compared with matched controls. This study suggests that athletes with preexisting cervical spine pathology were less likely to be drafted than controls. Players with preexisting cervical spine pathology demonstrated a shorter career than those without; however, statistically based performance and numbers of games started were not different. Players with cervical spinal stenosis and those with a history of previous surgery demonstrated no difference in performance-based outcomes and no reports of neurological

    2015-07-01

    Full Text Available Canadian and Torontonian Joe Shuster co-created Superman in 1938, drawing on his experiences at the Toronto Daily Star to define Clark Kent’s everyday life as a reporter. Despite Shuster’s Canadian co-authorship of the definitive American comic book superhero, John Bell suggests “Canadians are probably too wary of the uncritical portrayal of unrestrained heroism and power for the superhero genre ever to become a mainstay of the country's indigenous comic art” (84. Bell’s comments express national scepticism towards American myths of heroism, perhaps best summed up in the equally iconic Canadian trope of the ‘beautiful loser’. Whilst comic books may heighten these distinct senses of a national narrative, they are also the potential sites of encounter for intersecting national cultural narratives. Onesuch encounter can be seen in the recent “Justice League Canada” storyline of American publisher DC Comics’ Justice League United. Echoing its past connections with Canada, DC Comics’ Canadian cartoonist Jeff Lemire has created a superhero team storyline set explicitly in Northern Ontario, Canada, also introducing an Indigenous female superhero named Equinox to the DC comic book universe. Cree, and from Moose Factory, Ontario, the hero Equinox is in everyday life the teenager Miiyahbin Marten. Whilst the ‘DC universe’ is firmly a realm of the fantastic, Lemire’s storyline underscores how its characters provide real-life negotiations of American, Canadian and Indigenous identity. National boundaries, identities and sovereignties are potentially re-enforced and challenged through “Justice League Canada,” and particularly in the visualisation of Equinox. The mainstream storyworlds of American comic books are complicated by this negotiation of plural sovereignties.

    Full Text Available Purpose: The purpose of this study was to examine cortical thickness and subcortical volumes in professional rugby players with an extensive history of concussions compared to control subjects. Method: Participants included 24 active and former professional rugby league players [Age M(SD = 33.3(6.3; Range = 21–44] with an extensive history of concussion and 18 age- and education-matched controls with no history of neurotrauma or participation in contact sports. Participants underwent T1-weighted imaging and completed a neuropsychological battery, including two tests of memory. Whole brain cortical thickness analysis and structural volume analysis was performed using FreeSurfer version 6.0. Results: Professional rugby league players reported greater alcohol consumption (p < .001 and had significantly worse delayed recall of a visually complex design (p = .04. They did not differ from controls on other clinical outcome measures. There were no differences in cortical thickness between the groups. Professional players had smaller whole brain (p = .003, bilateral hippocampi (ps = .03, and left amygdala volumes (p = .01 compared to healthy controls. Within the players group, there were significant associations between greater alcohol use and smaller bilateral hippocampi and left amygdala volumes. There were no associations between structural volumes and history of concussions or memory performance. Conclusions: The literature examining cortical thickness in athletes with a history of multiple concussions is mixed. We did not observe differences in cortical thickness in professional rugby league players compared to controls. However, smaller subcortical volumes were found in players that were, in part, associated with greater alcohol consumption.

    The paper explores competitive balance in top tier English league football from its inception in 1888. It examines the extent to which finishing in the top four positions in successive seasons is the preserve of a small number of clubs. Using a range of statistical measures, the analysis shows that the current high levels of competitive imbalance are not new phenomena. The overall pattern approximates a ‘U curve’: current patterns parallel those in the 1890s. In the early years of English lea...

    This paper examines the impact of receiving a new stadium on team franchise values. I argue that a new stadium will increase the franchise values of teams regardless of how construction was financed. A team playing in a stadium that it owns will be able to capitalize the value of the stadium in the team’s franchise value and will thus have a higher franchise value. Using panel data for Major League Baseball teams from 1990-2002, I find that, after controlling for team quality and metro area d...

    Full Text Available Introduction. The main aim of the study was to assess the strength of the shoulder rotator muscles of a group of second-league volleyball players. These muscles are assumed to have a crucial impact on attack effectiveness in volleyball. Strength was assessed based on peak torque values obtained for the rotator muscles measured using the maximal voluntary contraction (MVC method. Torque was measured in both limbs and the differences between the two limbs were examined. The torque values obtained for the volleyball players were also compared against those measured in a group of students who had never trained any sports.

    The physical match demands for a newly promoted European Super League (ESL) squad were analysed over a full season using global positioning systems. Players were classified into four positional groups: outside backs (OB), pivots (PIV), middle unit forwards (MUF) and wide running forwards (WRF). MUF covered less total distance (4318 ± 570 m) than WRF (6408 ± 629 m), PIV (6549 ± 853) and OB (7246 ± 333 m) (P 0.05). WRF (36 ± 5) and MUF (35 ± 6) were involved in more collisions than OB (20 ± 3) and PIV (23 ± 3; P franchises.

    This paper assesses the role of distance in professional team sports, taking the example of football (soccer). We argue that a team’s performance in terms of scored and conceded goals decreases with the distance to the foreign playing venue. To test this hypothesis empirically, we investigate 6,389 away games from the German Football Premier League (’Erste Deutsche Bundesliga’) between the playing seasons 1986-87 and 2006-07. We find that distance increases a guest team’s propensity to conced...

It will pursue three objectives: 1 evaluate resources usage, 2 analyze the productivity levels of the football teams and the sports results, and 3 see the influence of participation experience in reference to productivity and sports results. Using Malmquist Productivity Index, the results reflect a lack of consistent progression of efficiency, productivity, and technical change. This competition does not reward the efficient usage of resources and there is not a conclusive relationshop between permanence in the competition and productivity.

    To identify the frequency of violent commercials during the major league baseball playoffs in 1998 and to compare it with the 1996 playoffs. All 4 World Series games televised on the Fox Television Network (Fox), all 6 National League Championship Series (NLCS) televised by Fox, and 5 of 6 American League Championship Series (ALCS) playoff games televised by the National Broadcasting Company (NBC) were videotaped in October 1998. The results were compared with a similar study that analyzed the 1996 playoffs. Forty-four commercials (11.0 per game) that included violent interactions were noted during the World Series, 53 violent commercials (8.8 per game) during the NLCS, and 40 (8.0 per game) during the ALCS for a total of 137. Of these 137 violent commercials, 78 contained at least 1 violent act, 126 contained at least 1 violent threat, and 12 contained evidence of at least 1 violent consequence. One hundred five of the 137 violent commercials (76.6%) were television promotions and 23 (16.8%) were for big-screen movie promotions. Twenty-three of 35 big-screen movie promotions (65.7%) were violent. Ten of the 137 violent commercials (7.3%) contained obvious blood, of which 9 were televised by NBC. There were, however, an additional 20 commercials televised by Fox that contained visible blood if the videotape was slowed or paused. Sixty-three of the 137 violent commercials (46.0%) used fire and explosions, of which 53 were televised by Fox and 10 by NBC. Guns were involved in 86 of 137 violent commercials (62.8%), with Fox accounting for 64 (6.4 per game) and NBC accounting for 22 (4.4 per game). Knives were used in 1 violent commercial on both Fox and NBC. Comparisons that can be made to 1996 include the following: 1) violent commercials during the World Series (both televised by Fox) increased from 10.1 to 11.0 per game; and 2) violent commercials during the ALCS (both televised by NBC) increased from 6.0 to 8.0 per game.

    To identify the frequency of violent television commercials aired during major league baseball playoffs, traditionally thought to be a family-oriented viewing time. All 6 World Series games televised on the Fox Television Network (Fox), all 5 American League Championship Series playoff games televised by the National Broadcasting Company (NBC), and 4 first-round playoff games televised by ESPN Sports Television Network (ESPN) were videotaped in October 1996. During the 15 televised games reviewed, 104 (6.8%) of the 1528 commercials contained violent content. Sixty-one commercials (10 per game) that included violent interactions were noted during the World Series, 30 (6 per game) during the American League Championship Series, and 13 (3 per game) during the 4 first-round playoff games for a total of 104. In these 104 violent commercials, 69 contained at least 1 violent act, 90 contained at least 1 violent threat, and 27 contained evidence of at least 1 violent consequence. Seventy (67.3%) of the violent commercials were promotions for television programs, 7 (6.7%) were cable television program advertisements, and 20 (19.2%) were big-screen movie promotions. Twenty (71.4%) of 28 big-screen movie promotions were violent. Twenty-two (21.2%) of the 104 violent commercials and 7 "nonviolent" commercials contained blood or other graphic content, all of which were televised during the Fox presentation of the World Series. Fox also accounted for all 24 violent commercials that used a knife. Guns were involved in 25 violent commercials on NBC (5.0 per game), in 20 on Fox (3.33 per game), and in 7 on ESPN (1.75 per game). Overt violent content in commercials during the 1996 major league playoffs was common and consisted mainly of promotions for television programs and big-screen movies. It is counterintuitive to find such commercials in nonviolent programming and makes it difficult for parents to avoid exposing their children to this form of violence.

    Full Text Available The best choice for feeding the newborn child is breast milk, and when it is not possible to breastfeed a baby, the breast milk is replaced by lacteal formula, which is why numerous studies focus their attention on the analysis of the diverse components of baby formula as well as functions in the breastfed baby. Fatty acids are components of great nutritional importance in the fetus and in the newborn child. Nowadays it is estimated that the fetus, during the last trimester of the gestational period and the newborn child, during the first six months of life, need a great contribution of araquidonic and docosahexaenoic acids, due to the fact that the speed of transformation of the predecessors to the hepatic level are not sufficient to cover the metabolic requirements of these fatty acids and it is the mother who contributes them through placental transport during gestation and her milk during lactation. The Organization of Food and Agriculture (FAO, the World Health Organization (WHO, the European Society of Gastroenterology, Hepatology and Pediatric Nutrition (ESPGHAN and the American Academy of Pediatrics recommend that lacteal formula imitate the composition of the breast milk, especially in the fatty polyunsaturated acids (PUFA.

    The current study retrospectively investigated the differences in anthropometric and fitness characteristics of junior rugby league players selected onto a talent identification and development (TID) programme between long-term career progression levels (i.e., amateur, academy, professional). Retrospective design. Former junior rugby league players (N=580) selected to a TID programme were grouped according to their career progression level. Anthropometric (height, sitting height, body mass and sum of four skinfolds), maturational and fitness (power, speed, change of direction speed and estimated V̇O2max) assessments were conducted at 13-15 years. Multivariate analysis of covariance (MANCOVA) analyzed differences between career progression levels controlling for chronological age. 57.1% and 12.1% of players selected to the TID programme progressed to academy and professional levels in rugby league, respectively. Sum of four skinfolds (η(2)=0.03), vertical jump (η(2)=0.02), 10 m (η(2)=0.02), 20 m (η(2)=0.02), 30 m (η(2)=0.02), and 60 m (η(2)=0.03) speed, agility 505 left (η(2)=0.06), agility 505 right (η(2)=0.05) and estimated V̇O2max (η(2)=0.03) were superior within junior players who progressed to professional compared to amateur levels. No significant differences were identified between future academy and professional players for any measure. Findings suggest that lower sum of four skinfolds and advanced fitness characteristics within junior (13-15 years) rugby league players may partially contribute to long-term career progression. Therefore, TID programmes within rugby league should aim to assess and develop body composition and fitness characteristics, especially change of direction speed. However, TID programmes should also consider technical, tactical and psycho-social characteristics of junior rugby league players that may be important for long-term career progression.

    Full Text Available La leche y los productos lácteos son fuente de proteínas de alto valor biológico. Algunas de éstas presentan actividades biológicas, nutricionales y funcionales en el ser humano. En los últimos años se ha reportado que los péptidos, derivados de las proteínas lácteas, son capaces de influir positivamente en la salud del consumidor. Sin embargo, éstos no ejercen beneficio alguno, más allá del aporte nutricional, cuando forman parte de las proteínas lácteas nativas, por lo que es necesario someter a las proteínas a procesos de hidrólisis enzimática. Este proceso puede llevarse a cabo por los microorganismos propios de la leche o por aquellos que son inoculados durante la elaboración y por la adición de enzimas comerciales utilizadas durante el procesado. Cabe señalar que el efecto hidrolítico no se limita a la elaboración de los productos lácteos, sino que continúa durante la maduración y la vida en el anaquel. Así mismo, diversas investigaciones han evidenciado que la actividad de las enzimas gastrointestinales es determinante en la hidrólisis que experimentan las proteínas lácteas. De tal forma que la liberación de los péptidos, aunada al tamaño, hidrofobicidad y secuencia de los mismos constituyen requisitos indispensables para convertirlos en péptidos con actividad biológica. Éstos últimos, también considerados como péptidos bioactivos o biopéptidos, han despertado recientemente el interés de los investigadores debido a que pueden influenciar favorablemente las funciones que llevan a cabo los sistemas inmune, gastrointestinal, nervioso y cardiovascular impactando la salud del consumidor. En esta revisión de literatura, se abordaron los mecanismos por los cuales son generados los biopéptidos derivados de proteínas lácteas y los efectos fisiológicos que producen.

    Full Text Available Smart economy implies the development of key factors like global economy growth, competition, economic progress, economic prosperity, innovation. In the European top-level football, like the case of the British Premier League, financial indicators have demonstrated that the factors that define smart economy can be identified. The new rules of the financial fair-play policies and the ever growing revenues for television rights have created a new market in sports economy, one that identifies itself with the criteria identifies in studies regarding smart economy. This paper comparatively examines the determinants of four indicators of the football team quality in the British Premier League, in order to find out whether a common set of potential determinants could be effective in improving all four indicators of quality, without worsening any of them. This allows finding what measures undertaken at the level of football teams could raise the football team quality. Considering the subjective and multidimensional nature of the football team quality, we first propose four indicators that might be appropriate to define this latent summative measure. Then we select a number of four potentially common determinants of the football team quality, and finally discuss the empirical results, based on panel generalized least squares regression models. The television broadcasting rights are found to be the most important determinant of the football team quality.

    Hamstring injuries constitute one of the most concerning injuries in English Premier League football, due to its high primary incidence but also its recurrence. Functional methods assessing hamstring function during high-risk performance tasks such as sprinting are vital to identify potential risk factors. The purpose of this study was to assess horizontal force deficits during maximum sprint running on a non-motorized treadmill in football players with previous history of hamstring strains as a pre-season risk-assessment in a club setting. 17 male football players from one Premier League Club were divided into 2 groups, experimental (n=6, age=24.5±2.3 years) and control (n=11, age=21.3±1.2 years), according to history of previous hamstring injury. Participants performed a protocol including a 10-s maximum sprint on a non-motorized treadmill. Force deficits during acceleration phase and steady state phases of the sprint were assessed between limbs and between groups. The main outcome measures were horizontal and vertical peak forces during the acceleration phase or steady state. There were no significant differences in peak forces between previously injured and non-injured limbs, or between groups, challenging the ideas around functional force deficits in sprint running as a diagnostic measure of hamstring re-injury risk. © Georg Thieme Verlag KG Stuttgart · New York.

    This study examined agreement between self-perceived sleep and sleep estimated via activity monitors in professional rugby league athletes. 63 athletes, from three separate teams wore actigraphy monitors for 10.3 ± 3.9 days. During the monitoring period, ratings of perceived sleep quality (on a 1-5 and 1-10 Likert scale), and an estimate of sleep duration were recorded daily. Agreement between sleep estimated via activity monitors and self-perceived sleep was examined using mean bias, Pearson correlation (r) and typical error of the estimate (TEE). 641 nights of sleep were recorded, with a very large, positive correlation observed between sleep duration estimated via activity monitors and subjective sleep duration (r = 0.85), and a TEE of 48 minutes. Mean bias revealed subjective sleep duration overestimated sleep by an average of 19.8 minutes. The relationship between sleep efficiency estimated via activity monitors and self-perceived sleep quality on a 1-5 (r = 0.22) and 1-10 Likert scale (r = 0.28) was limited. The outcomes of this investigation support the use of subjective measures to monitor sleep duration in rugby league athletes when objective means are unavailable. However, practitioners should be aware of the tendency of athletes to overestimate sleep duration.

    To investigate the influence of daily and exponentially weighted moving training loads on subsequent nighttime sleep. Sleep of 14 professional rugby league athletes competing in the National Rugby League was recorded using wristwatch actigraphy. Physical demands were quantified using GPS technology, including total distance, high-speed distance, acceleration/deceleration load (SumAccDec; AU), and session rating of perceived exertion (AU). Linear mixed models determined effects of acute (daily) and subacute (3- and 7-d) exponentially weighted moving averages (EWMA) on sleep. Higher daily SumAccDec was associated with increased sleep efficiency (effect-size correlation; ES = 0.15; ±0.09) and sleep duration (ES = 0.12; ±0.09). Greater 3-d EWMA SumAccDec was associated with increased sleep efficiency (ES = 0.14; ±0.09) and an earlier bedtime (ES = 0.14; ±0.09). An increase in 7-d EWMA SumAccDec was associated with heightened sleep efficiency (ES = 0.15; ±0.09) and earlier bedtimes (ES = 0.15; ±0.09). The direction of the associations between training loads and sleep varied, but the strongest relationships showed that higher training loads increased various measures of sleep. Practitioners should be aware of the increased requirement for sleep during intensified training periods, using this information in the planning and implementation of training and individualized recovery modalities.

    Talar osteochondral lesions represent challenging clinical entities, particularly in high-demand athletes. Surgical treatment of large lesions often requires a 2-step procedure, or the use of osteotomy in the case of autologous osteochondral transfer, which can delay return to sport. A professional rugby league player underwent surgery for a complex injury to the ankle. A talar osteochondral lesion with a maximal diameter of 15 mm was treated in an arthroscopic fashion using the cartilage taken from the completely displaced osteochondral fragment. Cartilage was cut into chips and combined with bone graft product containing platelet-derived growth factor and a porous collagen scaffold. Autologous cartilage was then reimplanted arthroscopically. The patient was allowed full ankle motion from 2 weeks postoperatively, and weightbearing was commenced at 6 weeks. Follow-up imaging and functional outcomes, including return to sport, were assessed at regular intervals. The patient was able to return to professional rugby league by 23 weeks postoperatively. Magnetic resonance imaging at 16 months postoperatively showed restoration of the subchondral plate and osseous infill. At final follow-up, the patient remained pain free and was playing at preinjury level. This report describes good outcomes using a novel, 1-step cartilage repair technique to treat a large talar osteochondral lesion in a professional athlete. Level V: Expert opinion.

    Full Text Available In this article, we explore the relationship between public recreation policy and planning and the transformation of urban governance in the context of the Police Athletic League centers in Baltimore, Maryland. In light of contemporary discussions of the role of youth programs for sport and physical activity within post-industrial cities, the origination, development, and eventual demise of Baltimore’s network of Police Activity League centers is an instructive, if disheartening, saga. It illustrates the social and political rationales mobilized in justifying recreation policy and programming, the framing of sport and physical activity as preventative measures towards crime and juvenile delinquency, and the precarity of such initiatives given the efficiency-driven orthodoxies of neoliberal urban entrepreneurialism (Harvey, 1989. This analysis emphasizes how the PAL centers were designed to ‘fill the void’ left by a declining system of public recreation, thereby providing an example of a recreation program as part of the “social problems industry” (Pitter & Andrews 1997.

    Although there is growing awareness of the impact of diet on health, little attention has been given to the food available in our sports stadia. We used a football club (Citygrene FC) - Citygrene is a fictional name - in the English Premier League as a case study to examine the attitudes of male and female football supporters to the food and drink available at their home stadium (Citygrene Stadium). The research design used five focus groups of male and female fans. The discourse was audiotaped, transcribed, coded and analysed for themes. A football stadium in the English Premier League, England. The participants were season ticket holders drawn from two stands at Citygrene Stadium. The research showed a high level of dissatisfaction with the food and drink supplied. There were key differences in the views of the male and female participants in the focus groups, with the women more concerned about wider issues such as the lack of healthy food. Both men and women were aware of their role as consumers and felt that there was an opportunity for Citygrene to improve their catering profits, if they provided a better selection of food and drink and an improved service. The study shows that there is a demand for healthier food options (and a wider choice of food and drink in general), which may provide an economic opportunity for stadium and catering managers. In addition, a stadium may be considered a potential 'healthy setting', which can serve as a supportive environment for healthier food choices.

    Full Text Available The aim of this investigation was to assess whether the demands of the modern English competitive soccer season would be reflected in the mood states of professional soccer players. Sixty-nine male participants either activity competing in English soccer leagues or resident in England were recruited and grouped accordingly as professional soccer players, university level soccer players, Sunday league soccer players, or non-sporting controls. On three separate occasions; at the beginning, at the middle, and finally towards the end of the English soccer season, participants completed both the Profile of Mood States (POMS questionnaire as well as a questionnaire related to their teams’ performance in addition to their perceived life stress. Results showed the POMS scores to differ over the season in relation to the groups’ standard of competition. ANOVAs demonstrated this pattern to be significant for the dependent measures of tension, depression, and confusion with significant group by time interactions (95% level of confidence. At the outset of the season professionals had the most positive POMS profile, however, as the season progressed they showed the greatest change towards a negative profile. These results indicate that English soccer is placing professional players at a predisposition of demonstrating POMS commensurate with negative adaptation to training, having important implications for their long-term performance and health.

    Literature has attempted to correlate pitching workload with risk of ulnar collateral ligament (UCL) injury; however, limited data are available in evaluating workload and its relationship with the need for revision reconstruction in Major League Baseball (MLB) pitchers. We identified 29 MLB pitchers who underwent primary UCL reconstruction surgery and subsequently required revision reconstruction and compared them with 121 MLB pitchers who underwent primary reconstruction but did not later require revision surgery. Games pitched, pitch counts, and innings pitched were evaluated and compared for the seasons after returning from primary reconstruction and for the last season pitched before undergoing revision surgery. The difference in workload between pitchers who did and did not require revision reconstruction was not statistically significant in games pitched, innings pitched, and MLB-only pitch counts. The one significant difference in workload was in total pitch counts (combined MLB and minor league), with the pitchers who required revision surgery pitching less than those who did not (primary: 1413.6 pitches vs. revision: 959.0 pitches, P = .04). In addition, pitchers who required revision surgery underwent primary reconstruction at an early age (22.9 years vs. 27.3 years, P risk for injury after primary UCL reconstruction. However, correlations of risk may be younger age and less MLB experience at the time of the primary reconstruction. Copyright © 2017. Published by Elsevier Inc.

    Medial ulnar collateral ligament (MUCL) reconstruction is commonly performed on Major League Baseball (MLB) pitchers. Previous studies have reported that most pitchers return to presurgical statistical performance levels after MUCL reconstruction. Pitching performance data--specifically, earned run average (ERA), walks and hits per inning pitched (WHIP), winning percentage, and innings pitched--were acquired for 168 MLB pitchers who had undergone MUCL reconstruction. These data were averaged over the 3 years before surgery and the 3 years after surgery and also acquired from 178 age-matched, uninjured MLB pitchers. Of the pitchers who had MUCL reconstruction surgery, 87% returned to MLB pitching. However, compared with presurgical data, pitching performance declined in terms of ERA (P = .001), WHIP (P = .011), and innings pitched (P = .026). Pitching performance also declined in the season before the surgery compared with previous years (ERA, P = .014; WHIP, P = .036; innings pitched, P risk factor for requiring surgery. In addition, there is an increased risk of MUCL reconstruction for pitchers who enter the major leagues at a younger age. Copyright © 2014 Journal of Shoulder and Elbow Surgery Board of Trustees.

    To our knowledge, this is the first study to show an association between concussion, cognition, and anatomical structural brain changes across the age spectrum in former National Football League athletes. To assess the relationship of hippocampal volume, memory performance, and the influence of concussion history in retired National Football League athletes with and without mild cognitive impairment (MCI). This retrospective cohort study assessed differences between groups, mean hippocampal volumes, and memory performance by computing age quintiles based on group-specific linear regression models corrected for multiple comparisons for both athletes and control participants. The study was conducted starting in November 2010 and is ongoing at a research center in the northern region of Texas. This current analysis was conducted from October 9, 2013, to August 21, 2014. Participants included 28 retired National Football League athletes, 8 of whom had MCI and a history of concussion, 21 cognitively healthy control participants, and 6 control participants with MCI without concussion. Hippocampal volume, age, California Verbal Learning Test scores, and the number of grade 3 (G3) concussions. In addition, the number of games played was examined as an objective variable pertaining to football history. The mean (SD) age was 58.1 (13) years for the 28 former athletes and 59.0 (12) years for the 27 control participants. Retired athletes with concussion history but without cognitive impairment had normal but significantly lower California Verbal Learning Test scores compared with control participants (mean [SD], 52.5 [8] vs 60.24 [7]; P = .002); those with a concussion history and MCI performed worse (mean [SD], 37 [8.62]) compared with both control participants (P history of G3 concussion were more likely to have MCI (7 of 7) compared with retired athletes without a history of G3 concussion (1 of 5) older than 63 years (P = .01).

    To determine the frequency and circumstances of serious cervical cord injuries associated with rugby union and league football in New South Wales. Retrospective review of patients with rugby football-related cervical spinal cord injuries. The two central spinal units in NSW, from January 1984 to July 1996. Admission to spinal units; injury resulting in permanent tetraplegia. During the review period, 115 rugby football players (56 union and 59 league) were admitted to the spinal units because of cervical spinal cord injuries. 49 patients had resultant permanent neurological deficits (complete tetraplegia [quadriplegia])--26 associated with rugby union and 23 with rugby league. Two patients died of injury sequelae within two weeks of admission. There was no significant change in the rate of football-related admissions to spinal units for either code. There was a small decline in the number (from 15 in 1984 to 1987 to 7 in 1992 to 1996) and incidence (from 1.2 to 0.5 per 10,000 participants) of patients with tetraplegia associated with rugby union. When this decline was tested as a trend over the years, it was found to be statistically significant (P = 0.06). No significant trend was found in the tetraplegia data associated with rugby league. Cervical spinal cord injuries leading to complete tetraplegia were most commonly associated with scrum-like plays in union and with tackles in league. Serious cervical spinal injuries associated with both codes of rugby continue to occur in NSW. Rugby football in its various forms is still an inherently dangerous game.

    Full Text Available The National Football League (NFL has recently received significant negative media attention surrounding the safety of its players, revolving largely around the long term health risks of playing the sport. Recent premature deaths and instances of suicide associated with chronic traumatic encephalopathy and other football related injuries have brought the sport under increased scrutiny. By comparing mortality rates of the general population to mortality rates of players using publically available data from the 1970 and 1994 NFL seasons, we test whether participation in football is significantly harmful to the longevity of the players. We conclude that, in total, players in the NFL have lower mortality rates than the general population. However, there is evidence that line players have higher mortality rates than other players and that those who played more games have higher mortality rates than those who played fewer games.

    A 16-year-old Major League Baseball prospect presented with persistent shoulder pain associated with throwing. Magnetic resonance imaging (MRI) demonstrated a large osteochondritis dissecans lesion in the posterosuperior aspect of the glenoid. The patient was restricted from throwing and underwent therapy to improve range of motion and throwing mechanics. Eight months after initiating nonoperative treatment, an MRI arthrogram demonstrated a healed lesion. At follow-up 2 years after treatment, full relief of symptoms had persisted. Osteochondritis dissecans lesions of the glenoid are extremely rare, but have the potential to heal in overhead-throwing athletes. To our knowledge, this is the only case reported in the literature that demonstrates a healed osteochondritis dissecans lesion of the glenoid following nonoperative treatment.

    2017-04-01

    Full Text Available Indian Premier League is a twenty-over format cricket tournament of teams representing different Indian cities. Beginning 2008, it is established now as a grand annual affair. The team franchises are auctioned on long term basis, whereas cricketers are auctioned every season under certain conditions. Despite such wealth of information, studies on IPL auctions are rare barring four cited models. The present paper studies the results of year 2011 English-style auction of cricketers and recalibrates the old yet most accurate model by Rastogi and Deodhar (2009. Both models use ordinary least square method of regression albeit with different variable. The old models lack predictive power, whereas the recalibrated model presented displays better predictive capability as compared to earlier models. It also succeeds in reducing overall predictability gap and stands significantly parsimonious vis-à-vis previous models. Further, the final model presented is applied on 2013 and 2014 auction data to show superior results.

    What motivates the global movements of infertile people searching for assisted reproductive technologies (ARTs)? In this article, we attempt to answer this question by exploring infertile patients' practices of so-called "fertility tourism." Based on ethnographic research carried out with nearly 300 infertile travelers in two major ART centers--one in the global hub of the United Arab Emirates and the other at a major East Coast Ivy League university--we examine a diverse set of reasons for reproductive travel. We argue that reproductive "tourism" should be reconceptualized as reproductive "exile" in that infertile couples feel barred from accessing ARTs in their home countries. Listening to reproductive travel stories is key to understanding infertile couples' transnational "quests for conception." Stories of two couples, one from Lebanon and one from Italy, demonstrate the poignancy of these quests and begin to shed light on the complex calculus of factors governing this global movement of reproductive actors.

  19. Tests of Racial Discrimination in a Simple Financial Market: Managers in Major League Baseball

    Full Text Available This study tests for racial discrimination against minority managers in Major League Baseball using financial-market imbalances as it relates to the wagering marketplace for the sport. Using detailed betting data on the percentage bet on the favorite from Sports Insights, we test for prejudice against minority mangers using an ordinary least squares multiple regression model. The results reveal that bettors have a clear preference for the favored team as the percentage bet on the favorite increases with the odds on the favorite. In addition, they prefer road favorites by an even greater margin. In terms of minority managers, there is no evidence of discrimination against minorities. In fact, bettors prefer to wager on minority managers by a statistically significant margin when they are favorites. This finding suggests that either the participants in this financial marketplace are not prejudiced against minority managers or the financial incentives inherent in the market drive out discrimination against the minority managers.

    Full Text Available In this paper, the problem of choosing a set of most separable colors in a given environment is discussed. The proposed method models the process of generating theoretically computed best colors, printing of these colors through a color printer, and imaging the printed colors through a camera into an integrated framework. Thus, it provides a feasible way to generate practically best separable colors for a given environment with a set of given equipment. A real world application (robust color choice for small-size league RoboCup competition is used as an example to illustrate the proposed method. Experimental results on this example show the competitiveness of the colors learned from our algorithm compared to the colors adopted by other teams which are chosen via an extensive trial and error process using standard color papers.

    2017-07-01

    Full Text Available In recent years, the National Football League (NFL has made an effort to lower the prevalence of concussions, partially by enacting rule changes designed to limit contact to the head. This study aims to determine whether NFL rule changes from 2009 – 2015 have resulted in a decrease in the number of reported concussions through analyzing publicly available injury reports, which were compared with rule changes for each season. A second component of the study aims to determine whether teams are underreporting the number of concussions suffered by gathering concussion data for each team. This study found that there was a general increase in the number of concussions from 2009 – 2015 and it is not possible to determine whether rule changes are effective in decreasing head impact exposure. This study also found that certain teams reported a significantly low number of concussions throughout the years analyzed, and underreporting is likely occurring.

    The aim of this study was to determine the structure of morphological and motor characteristics of Croatian first league female football players and their impact on the estimated quality of the players. According to the goal of the research, a sample consisted of 70 Croatian first league female football players. Participants were measured in 18 tests for assessing morphological characteristics, a set of 12 basic motor abilities tests and a set of 7 tests for assessing football-specific motor abilities. Exploratory factor analysis strategy was applied separately to all measured tests: morphological, basic motor abilities and football specific motor abilities. Factor analysis of morphological tests has shown existence of 3 significant latent dimensions that explain 64% of the total variability. Factors are defined as transverse dimensionality of the skeleton and voluminosity (35%), subcutaneous fat tissue (16%) and longitudinal dimensionality of the skeleton (13%). In the area of basic motor abilities, four factors were extracted. The first factor is responsible for the integration of agility and explosive power of legs, i.e. a factor of movement regulation (agility/lower body explosiveness) (23%), the second one defines muscle tone regulation (15%), the third one defines the frequency of leg movements (12%), while the fourth one is recognized as responsible for the manifestation of basic strength, particularly of basic core strength (19%). Two factors were isolated in the space of football-specific motor abilities: football-specific efficiency (53%) and situational football coordination (27%). Furthermore, by use of factor analysis on extracted latent dimensions (morphological, basic and football specific motor abilities) two higher order factors (explaining 87% of common variability) were extracted. They were named morphological-motor factor (54%) and football-specific motor abilities factor (33%). It is assumed that two extracted higher-order factors fully

    Full Text Available Scope of this study was to identify motivational factors related to specific recreational sport event: 'Wild league' in water polo, which takes place in Dubrovnik, have very long tradition. First goal of the study is to determine the relationship between motivational factors related to this event, as well as with socio-demographic variables. Second goal is to determine the differences in motivational factors, according to several independent variables, mainly related to the previous experiences with sports and touristic destination. The cross-sectional study is conducted. The sample of 125 participants was examined, using the Questionnaire on sports event. All participants were Croatian citizens, excluding those who are born, and currently live in Dubrovnik. Major sports tourism motives of the potential tourists in this sporting event, were obtained. In general, the importance of the benefits of sports and tourist destination prevailed, as compared with their limitations, which appeared as an important factor only in participants who didn't visited Dubrovnik yet. At the participants, pull factors, i.e. advanced sports and travel motives slightly dominated over push motives, but statistically significant only in females, who expressed more sophisticated pulling tourist motives, such as the acquisition of knowledge about the destination. Correlations indicate that previous interest in sport, particularly in water polo and Wild League, are moderate positively associated with pushing motives. Moreover, previous recreationally engaging in sports, as well as destination-related origin, appeared as the important factors for having more emphasized pull motives for visiting this sport event. Level of the education did not appear as important factor in differentiating main type of motives in target population. Results provide initial information about the possibility of profiling potential tourists who could be motivated to visit the destination by this

  4. Aggression, Violence and Injury in Minor League Ice Hockey: Avenues for Prevention of Injury.

    Michael D Cusimano

    Full Text Available In North America, more than 800,000 youth are registered in organized ice hockey leagues. Despite the many benefits of involvement, young players are at significant risk for injury. Body-checking and aggressive play are associated with high frequency of game-related injury including concussion. We conducted a qualitative study to understand why youth ice hockey players engage in aggressive, injury-prone behaviours on the ice.Semi-structured interviews were conducted with 61 minor ice hockey participants, including male and female players, parents, coaches, trainers, managers and a game official. Players were aged 13-15 playing on competitive body checking teams or on non-body checking teams. Interviews were manually transcribed, coded and analyzed for themes relating to aggressive play in minor ice hockey.Parents, coaches, teammates and the media exert a large influence on player behavior. Aggressive behavior is often reinforced by the player's social environment and justified by players to demonstrate loyalty to teammates and especially injured teammates by seeking revenge particularly in competitive, body-checking leagues. Among female and male players in non-body checking organizations, aggressive play is not reinforced by the social environment. These findings are discussed within the framework of social identity theory and social learning theory, in order to understand players' need to seek revenge and how the social environment reinforces aggressive behaviors.This study provides a better understanding of the players' motivations and environmental influences around aggressive and violent play which may be conducive to injury. The findings can be used to help design interventions aimed at reducing aggression and related injuries sustained during ice hockey and sports with similar cultures and rules.

    Concussions impair balance, visual acuity, and reaction time--all of which are required for high-level batting performance--but the effects of concussion on batting performance have not been reported. The authors examined this relationship between concussion and batting performance among Major League Baseball (MLB) players. Batting performance among concussed MLB players will be worse upon return to play than batting performance among players missing time for noninjury reasons. Cohort study; Level of evidence, 3. The authors identified MLB players who sustained a concussion between 2007 and 2013 through league disabled-list records and a Baseball Prospectus database. For a comparison group, they identified players who went on paternity or bereavement leave during the same period. Using repeated-measures generalized linear models, the authors compared 7 batting metrics between the 2 groups for the 2 weeks upon return, as well as 4 to 6 weeks after return, controlling for pre-leave batting metrics, number of days missed, and position. The authors identified 66 concussions and 68 episodes of bereavement/paternity leave to include in the analysis. In the 2 weeks after return, batting average (.235 vs .266), on-base percentage (.294 vs .326), slugging percentage (.361 vs .423), and on-base plus slugging (.650 vs .749) were significantly lower among concussed players relative to the bereavement/paternity leave players (time×group interaction, Pperformance after concussion is adversely affected and to identify better measures to use for return-to-play decisions. © 2015 The Author(s).

    The aim of this study was to assess how anterior cruciate ligament (ACL) ruptures with subsequent surgery reconstruction impact on the professional career of A1-A2 Italian women's volleyball league players. Using an observational study with a retrospective case-series design for ACL ruptures, 125 teams with 1488 players were monitored. Subjects had to report level, role, injury modality, lower limb injured, laterality, period of the season and age. A total of 34 ACL ruptures were reported. Thirty-three (97%) were non-contact and 1 (3%) with contact. Twenty-one (61.7%) occurred in landing from a jump attack, 3 (8.8%) in landing from wall jump, 1 (3%) with apparent contact and 9 (26.5%) in other landing conditions. The most injured knee was the left limb (22, 64.7%) respect to the right limb (12, 35.3%). Fourteen (41.2%) ruptures occurred in spikers, 10 (29.4%) in middle blockers, 6 (17.6%) in setters, 3 (8.8%) in liberos and 1 (3%) in opposite hitters. Nine (26.5%) occurred in pre-season period, 16 (47%) in the first round, 4 (11.8%) in the second round, and 5 (14.7%) during play-off. The average age of the first ACL rupture was 23±3 years. We observed that female volleyball players of A1-A2 Italian volleyball league occurred mostly in a left non-contact ACL rupture during a landing condition and the spikers were the players most at risk. Therefore, it is desirable that coaches teach players variations of landing in order to avoid possible chronic overloading of ACL.

    Eye and orbital injuries are a significant risk to professional hockey league players and have resulted in career-ending injuries. The goal of this study was to determine the incidence, value lost, mechanism, and effect of visors on eye and orbital injuries over the last 10 National Hockey League (NHL) seasons: 2002-2003 to 2012-2013. Retrospective case-control study. Participants were 8741 NHL players who had played at least 1 game during the last 10 seasons. Using The Sports Network (TSN), ProSportsTransactions, and the Sporting News Hockey Register, NHL players were searched to identify eye and orbital injuries. The mechanism of injury was obtained from media reports and direct observation from online videos. The number of players wearing visors each year was obtained from The Hockey News annual visor survey. A total of 149 eye or orbital injuries over the last 10 seasons resulted in an overall incidence of 2.48 per 10 000 athlete exposures. A total of 1120 missed games led to a lost financial value of more than $33 million. Visor use among players grew from 32% in 2002-2003 to 73% in 2012-2013, and there was a significantly increased risk for having an eye or orbital injury when a visor was not worn (OR 4.23, 95% CI 2.84-6.30). Most injuries were a result of being hit by a deflected or direct puck (37%) followed by being struck by a high stick (28%). Players who did not wear a visor were found to be involved in more fights, hits, and penalty minutes (p < 0.001). Eye and orbital injuries are mostly accidental in nature and represent a significant risk and cost to the NHL and its players. Eye and orbital injuries are significantly more likely in players who do not wear visors. Copyright © 2014 Canadian Ophthalmological Society. Published by Elsevier Inc. All rights reserved.

    Full Text Available This article concerns with new and traditional practises in agriculture in Alxa League in the Inner Mongolia of China. For such a purpose, the DISPAA Department of University of Florence (Italy collaborated with the University of Tuscia (Italy, which has been one of the Italian executives for the Beijing Wind Dust Control Project under the framework of the Sino-Italian Cooperation Programme on Environmental Protection. In the context of ADAM Project, the Inner Mongolia was indicated as a potential hot-spot due to the combination of climatic change, human activities and the general phenomenon of desertification, which is an ongoing process in this area. During the past centuries, arid and semi-arid general environmental characteristics of Inner Mongolia’s landscape have conditioned the main course of economic development in rural areas. Into the Alxa League, a sub-case study situated around Jarantai City in the Alxa Left Banner was selected. During 2005-06, the work analysed the agricultural activities of the local rural population to evaluate if these might be able to cope with desertification and, more in general, with climatic change impacts. In particular, field surveys were implemented among local peasants, which were old herders or new farmers immigrated in the area, following a non-structured interview approach where the length of the interview was calibrated on the characteristics of the single interviewed. The interviews showed that soil fertility and water requirement (e.g. water drawdown and high evaporation rate that cause superficial salt crust formation are yet the main constraints to social and economic development of agriculture.

    Full Text Available Abstract Background This paper describes a case of C7 radiculopathy in a professional rugby league player after repeated cervical spine trauma. The report outlines the management of the patient following an acute cervical hyperflexion injury with chiropractic manipulation and soft tissue therapies. It also presents a change in approach to include distractive techniques on presentation of a neurological deficit following re-injury. The clinical outcomes, while good, were very dependent upon the athlete restricting himself from further trauma during games, which is a challenge for a professional athlete. Case presentation A 30-year old male front row Australian rugby league player presented complaining of neck pain after a hyperflexion and compressive injury during a game. Repeated trauma over a four month period resulted in radicular pain. Radiographs revealed decreased disc height at the C5-C6 and C6-C7 levels and mild calcification within the anterior longitudinal ligament at the C6-C7 level. MRI revealed a right postero-lateral disc protrusion at the C6-C7 level causing a C7 nerve root compression. Conclusion Recommendations from the available literature at the present time suggest that conservative management of cervical discogenic pain and disc protrusion, including chiropractic manipulation and ancillary therapies, can be successful in the absence of progressive neurological deficit. The current case highlights the initial successful management of a football athlete, and the later unsuccessful management. This case highlights the issues involvement in the management of a collision sport athlete with a serious neck injury.

    Coxon, Steven Vincent

    Spatial ability is important to science, technology, engineering, and math (STEM) success, but spatial talents are rarely developed in schools. Likewise, the gifted may become STEM innovators, but they are rarely provided with pedagogy appropriate to develop their abilities in schools. A stratified random sample of volunteer participants (n=75) ages 9-14 was drawn from 16 public school districts' gifted programs, including as many females (n=28) and children from groups traditionally underrepresented in gifted programs (n=18) as available. Participants were randomly divided into an experimental (n=38) and a control group (n=37) for an intervention study. All participants took the CogAT (form 6) Verbal Battery and the Project TALENT Spatial Ability Assessments. The experimental group participated in a simulation of the FIRST LEGO League (FLL) competition for 20 hours total over five consecutive days. All participants took the spatial measure another time. Experimental males evidenced significant and meaningful gains in measured spatial ability (Cohen's d = 0.87). Females did not evidence significant gains in measured spatial ability. This may be due to sampling error, gender differences in prior experience with LEGO, or differences in facets of spatial ability in the treatment or measurements. Further research studies with larger samples of females, other treatments and measurement tools, and longer treatment periods are recommended. The literature review revealed that FLL is beneficial for STEM engagement in both genders and its use in schools is recommended. The present study provides additional evidence for FLL's usefulness in increasing the number of individuals in the STEM pipeline.

    Full Text Available The area of tactics in soccer game is of particular importance for modern soccer development. The analysis and improvement of spatio-temporal indicators as well as the game principles related to tactics may be crucial to the achievement of competitive results. This study is aimed at comparing tactical manifestations of the teams competing in the top quality European club competition, the Champions League, and the best Serbian soccer championship by analyzing competitive activity. The results of the conducted research were obtained by observing an overall of 20 randomly selected matches, 10 of the Champions League (CL and 10 of the Serbian Super Liga (SSL, which is a sufficient number of matches for making conclusions about the competitions respectively. In the previously designed observing protocol, using a method of notation, we analyzed all the attacks completed by shooting at the opponent's goal. The structure of successfully realized attacks was assessed on the basis of: accuracy, types of realized offensive actions; area of starting the action, manner of realization of passes completed (assists and distance from the goal from which a shot on goal was executed. The study showed that there are certain common characteristics, but also there are differences in the structure of successfully realized attacks between the two analyzed competitions. The teams of the CL competition had significantly greater number of effective attacks per match (p = 0. 006, they realized their offensive activities with slightly greater number of players (p = 0.002 and number of passes (p = 0.000, whereas there are no significant differences in the area of starting successful attacks, the manner of realization of assists and distance from which shots on goal were executed. The study results may define certain guidelines in training technology when preparing the teams of the SSL competition for taking part in the European soccer cups.

    Full Text Available During lactation, both the nutritional and energetic requirements of suckling change gradually. These changes normally are accompanied by modifications in chemical composition of the milk. We investigated the temporal course of milk composition during lactation in a precocial caviomorph rodent, the "degu" (Octodon degus under laboratory condition. Female degus were kept in laboratory during gestation and lactation and fed with commercial food pellets. Milk was collected at three stages of lactation: early (days 5-8, n = 12, middle (days 15-21, n = 7 and late (days 26-40, n = 6, and analyzed for protein, carbohydrates, lipids, ash, total solids and energy. On average, carbohydrates decreased from 3.1 ± 0.3 % (early to 1.1 ± 0.3 % (late during lactation; lipids, protein, ash, total solids and energy remained about the same. Lipids, the main component of the milk, were 17.3 % and protein remained near 4.4 %. Over lactation, total energy concentration of milk remained near 4.0 kJ mL-1. The maintenance of milk composition during lactation may be related to the initially high energetic and nutritional requirements associated with a precocial reproductive modeDurante la lactancia, tanto los requerimientos energéticos como nutricionales de las crías cambian gradualmente. Estos cambios normalmente van acompañados por modificaciones en la composición química de la leche. Se investigaron los cambios temporales de la composición de la leche durante la lactancia en el roedor caviomorfo precocial "degu" (Octodon degus bajo condiciones de laboratorio. Las hembras de degu fueron mantenidas en el laboratorio durante preñez y lactancia, y fueron alimentadas con alimento comercial de conejo.

    Full Text Available This study deals with development of a "dulce de leche" (DL with coffee, with low caloric content and functional properties. Through rotational central composite design, eleven DLs were formulated with different polydextrose and sucralose levels. The results were analyzed by means of response surface and ANOVA. The addition of polydextrose led to the increase in moisture and water activity and reduction in the ash and soluble solids contents. In the formulations with greater levels of sucralose and polydextrose, there was an increase in the ash, acid and fiber content. Greater yield was achieved with greater concentrations of polydextrose and less substitution of sucrose by sucralose, allowing development of a new functional product with low caloric content.Esta pesquisa trata do desenvolvimento de um doce de leite com café, de baixo valor calórico e funcional. Por meio do delineamento composto central rotacional, foram formulados onze doces de leite com diferentes níveis de polidextrose e sucralose. Os resultados foram analisados por meio de superfície de resposta e ANOVA. A adição da polidextrose influenciou no aumento da umidade e atividade de água e redução nos teores de cinza e sólidos solúveis. Nas formulações com maiores níveis de sucralose e polidextrose, houve incremento no teor de cinza, acidez e fibras. Maiores rendimentos foram alcançados com maiores concentrações de polidextrose e menor substituição de sacarose por sucralose, possibilitando o desenvolvimento de um novo produto de baixo valor calórico e funcional.

Further on, by the formation of international organizations, codification has been allowed, as well as a progressive development of international law. Additionally, in the sense of preserving international peace and security, first the League of Nations was formed, and following the ending of World War II, the UN. Generally, the functioning of the United Nation's organs, has been regulated by legal rules, however political goals, tendencies, and mechanisms which the member states are using determine greatly the activity above all of the Security Council, but furthermore of the General Assembly, as a plenary organ. Nevertheless, the achieved results of the Commission for International Law in the meaning of creation of international conventions, as well as state adhering to the same, present unassailable achievements in the sense of development of international law. On the other hand, tendencies of motion of international relationships are aimed at establishing a multi-polar system in the international community. Today, the political scene is assuming a new appearance, by which the nearly built international system is already awaiting further progressive development.

    Full Text Available This article studies women’s participation in the work of philanthropic patriotism conducted by the Primrose League, a Conservative organisation which remained in activity throughout the First World War. The case of the Primrose League, whose female membership carried out the sort of philanthropic work that conformed to the traditional view of the sexual division of labour, is used to qualify the historiographical interpretation according to which during the war women’s social status went through a dramatic evolution. Discussion then turns to the ambiguous relation of the League’s hierarchy towards the issue of women’s citizenship, which highlights the fact that this organisation embodied a desire to resist the gender disturbances occasioned by the war.

    To evaluate whether players with a history of an anterior cruciate ligament reconstruction (ACLR) before the National Football League (NFL) Combine played or started fewer games and/or participated in fewer eligible snaps compared with NFL Combine participants without a history of knee injury or surgery. We performed a retrospective review of all players who participated in the NFL Combine between 2009 and 2015 and who had a history of an ACLR. NFL Combine participants were included if they had a previous ACLR or combined anterior cruciate ligament (ACL) injury and nonoperatively managed medial collateral ligament injury. The number of games started, number of games played, draft number, overall draft pick, and snap percentage for each position were determined. The mean value of each outcome metric was compared between case and control players. We identified 110 players who had an ACL injury (n = 76) or a combined ACL and medial collateral ligament injury (n = 34). Players in the ACLR group had a significantly worse mean draft pick number (difference of 30.2, P = .002) and mean draft round (difference of 0.8, P = .019) versus controls. Compared with control players, players in the ACLR group started and played significantly fewer games in both season 1 (difference of 2.7 games started, P < .001; difference of 2.7 games played, P < .001) and season 2 (difference of 7.4 games started, P < .001; difference of 3.0 games played, P = .003) and had a significantly lower snap percentage in both season 1 (difference of 23.1%, P < .001) and season 2 (difference of 24.0%, P < .001). Athletes at the NFL Combine who previously underwent an ACLR had significantly lower early-career NFL player metrics, including fewer games started, fewer games played, and a lower snap percentage, than uninjured controls. Defensive linemen, defensive backs, and linebackers were the 3 most affected positions. Players with a prior ACLR and combined meniscal-chondral pathology had

    Studies of the longevity of professional American football players have demonstrated lower mortality relative to the general population but they may have been susceptible to selection bias. To examine the association between career participation in professional American football and mortality risk in retirement. Retrospective cohort study involving 3812 retired US National Football League (NFL) players who debuted in the NFL between 1982 and 1992, including regular NFL players (n = 2933) and NFL "replacement players" (n = 879) who were temporarily hired to play during a 3-game league-wide player strike in 1987. Follow-up ended on December 31, 2016. NFL participation as a career player or as a replacement player. The primary outcome was all-cause mortality by December 31, 2016. Cox proportional hazards models were estimated to compare the observed number of years from age 22 years until death (or censoring), adjusted for birth year, body mass index, height, and position played. Information on player death and cause of death was ascertained from a search of the National Death Index and web-based sources. Of the 3812 men included in this study (mean [SD] age at first NFL activity, 23.4 [1.5] years), there were 2933 career NFL players (median NFL tenure, 5 seasons [interquartile range {IQR}, 2-8]; median follow-up, 30 years [IQR, 27-33]) and 879 replacement players (median NFL tenure, 1 season [IQR, 1-1]; median follow-up, 31 years [IQR, 30-33]). At the end of follow-up, 144 NFL players (4.9%) and 37 replacement players (4.2%) were deceased (adjusted absolute risk difference, 1.0% [95% CI, -0.7% to 2.7%]; P = .25). The adjusted mortality hazard ratio for NFL players relative to replacements was 1.38 (95% CI, 0.95 to 1.99; P = .09). Among career NFL players, the most common causes of death were cardiometabolic disease (n = 51; 35.4%), transportation injuries (n = 20; 13.9%), unintentional injuries (n = 15; 10.4%), and neoplasms (n = 15

    Full Text Available At this paper we shown the development of an algorithm to perform edges extraction based on fuzzy logic theory. This method allows recognizing landmarks on the game field for Humanoid League of RoboCup. The proposed algorithm describes the creation of a fuzzy inference system that permit evaluate the existent relationship between image pixels, finding variations on grey levels of related neighbor pixels. Subsequently, it shows an implementation of OTSU method to binarize an image that was obtained from fuzzy process and so generate an image containing only extracted edges, validating the algorithm with Humanoid League images. Later, we analyze obtained results that evidence a good performance of algorithm, considering that this proposal only takes an extra 35% processing time that will be required by traditional methods, whereas extracted edges are 52% less noise susceptible.

    The World Prohibition Federation, organized in 1909, and the International Record, published from 1917 to 1968, sought to internationalize the temperance movement by collecting and disseminating anti-drink news from around the globe. The Federation was based in London, and most of its activities were English-speakers. A British reformer named Guy Hayler served as its honorary president for thirty years and edited the "International Record" until his death in 1943. The Federation emphasized that prohibitionists comprised a moral community, united regardless of race, religion, nationality, or politics. Poorly funded, the Federation had difficulty competing with the World League against Alcoholism after the Anti-Saloon League of America organized this rival propaganda society in 1919.

    The aim of this study was to assess the physiological responses to an intensified rugby league competition and explore the relationships between fatigue and match performance. Prospective cohort study. Fifteen junior rugby league players (n=8 forwards, 7 backs; mean±SE, age 16.6±0.2 years; body mass 81.6±3.0kg; and height 178.9±1.8cm) competed in five 40min games over 5 days (two games each on days 1 and 2, one game on day 4, and no games on days 3 and 5). Over the competition, players performed a countermovement jump to assess neuromuscular fatigue, provided a fingertip blood sample to measure blood creatine kinase, and completed a questionnaire to monitor perceived wellbeing; ratings of perceived effort were recorded following each game. Global positioning system and video analysis of each game were used to assess match performance. Over the first 3 days, there were progressive and large increases in neuromuscular fatigue which peaked 12h after game 4 (forwards ES=4.45, p=0.014; backs ES=3.62, p=0.029), and muscle damage which peaked 1h post game 4 (forwards ES=4.45, p=0.004; backs ES=3.94 p=0.012), as well as reductions in perceived wellbeing. These measures gradually recovered over the final 2 days of the competition. Compared to the backs, the forwards experienced greater increases in creatine kinase following game 2 (ES=1.30) and game 4 (ES=1.24) and reductions in perceived wellbeing (ES=0.25-0.46). Match intensity, high-speed running, and repeated-high intensity effort bouts decreased in games 4 and 5 of the competition. Small to large associations were observed between the changes in fatigue, muscle damage and match performance, with significant correlations between creatine kinase and repeated high-intensity effort bout number (r=-0.70, p=0.031) and frequency (r=0.74, p=0.002) and low-speed activity (r=-0.56, p=0.029). Fatigue and muscle damage accumulate over an intensified competition, which is likely to contribute to reductions in high

    The present study was designed to further understand the psychosocial drivers of crowds impacting on the demand for healthcare. This involved analysing different spectator crowds for medical usage at mass gatherings; more specifically, did different football team spectators (of the Australian Football League) generate different medical usage rates. In total, 317 games were analysed from 10 venues over 2 years. Data were analysed by the ANOVA and Pearson correlation tests. RESULTS; Spectators who supported different football teams generated statistically significant differences in patient presentation rates (PPR) (F15, 618=1.998, P=0.014). The present study confirmed previous findings that there is a positive correlation between the crowd size and PPR at mass gatherings but found a negative correlation between density and PPR (r = -0.206, n=317, Pemergency medical care. In measuring demand for emergency medical services there is a need to develop a more sophisticated understanding of a variety of drivers in addition to traditional metrics such as temperature, crowd size and other physical elements. In this study we saw that spectators who supported different football teams generated statistically significant differences in PPR. What is known about this topic? Understanding the drivers of emergency medical care is most important in the mass gathering setting. There has been minimal analysis of psychological 'crowd' variables. What does this paper add? This study explores the psychosocial impact of supporting a different team on the PPR of spectators at Australian Football League matches. The value of collecting and analysing these types of data sets is to support more balanced planning, better decision support and knowledge management, and more effective emergency medical demand management. What are the implications for practitioners? This information further expands the body of evidence being created to understand the drivers of emergency medical demand and usage

    To examine self-reported patterns of alcohol consumption and experience of alcohol-related harms among professional Australian Football League (AFL) players. Cross-sectional survey of player alcohol consumption and self-reported alcohol-related harms among members of all 16 professional AFL clubs. Data relating to the 2006 football year were collected between 25 July and 30 August 2006 at regular football training sessions using a self-administered structured questionnaire. Risky/high-risk drinking for long- and short-term harm at different times of the year; Alcohol Use Disorders Identification Test (AUDIT) score. 582 AFL players completed the questionnaire (an 83% response rate). Alcohol consumption varied at different times of the year. During the playing season (approximately 22 weeks), the level of risky/high-risk consumption for long-term harm in AFL players (11/564 [2%]) was typically lower than in age-matched Australian men in the general population (15%). However, risky/high-risk consumption for long-term harm was higher in AFL players during the end-of-season period (approximately 2 weeks) (303/561 [54%]) and vacation period (6-8 weeks) (231/559 [41%]) than in age-matched Australian men. Risky/high-risk drinking for short-term harm on a monthly basis was frequent at all times of the year (eg, 395/560 [71%] in the pre-season period). The mean AUDIT score was 8.8 (95% CI, 8.4 to 9.1; range, 0 to 36). Reports of harmful effects of drinking and negative consequences, such as getting involved in a fight (physical or verbal) while drinking (146/556 [26%]), were common. Risky/high-risk consumption for short-term harm on a monthly basis was associated with a variety of player characteristics, such as usually drinking in public locations (odds ratio, 1.55 [95% CI, 1.02 to 2.35]). AUDIT score was associated with variables such as marital status, with married players scoring more than two points lower (95% CI, - 3.58 to - 0.58) than single players. Formal club rules

Il esquisse d'abord la relation souvent difficile entre l'automobile et la ville d'une part et la société en général. Il revient sur le rôle de la signalisation routière dont la mise en place a contribué à encadrer ces rapports. À la veille de la Première Guerre Mondiale, des milliers de panneaux décorent déjà les routes européennes. Depuis la guerre, la nouvelle Société des Nations réussit à s'accaparer les discussions sur la signalisation routière au début des années 1920, puis commence ses travaux sur la signalisation routière spécifiquement urbaine à partir de 1926. La Conférence Européenne sur le Trafic Routier en 1931 est le sommet de ce mouvement. Le système n'a pas changé fondamentalement depuis. A l'inverse des propositions des représentants urbains, la SdN n’est cependant pas devenue le coordinateur central des problèmes de signalisation routière. L’article conclut par nuancer la qualification des panneaux routiers comme des hiéroglyphes par le journaliste français Baudry de Saunier en 1931.This article discusses road traffic signs in the Interwar years. The article first sketches the often difficult relationship between the car and the city and society at large. It proposes road signs were introduced in part to mitigate this antagonistic relation. On the eve of the First World War thousands of signs already adorned European roads. After the war the new League of Nations managed to seize discussions on road signs in the early 1920s, and started to work on specifically urban road signs from 1926 onwards. The European Conference on Road Traffic in 1931 formed the apex of this development. The system has not fundamentally changed since. Contrary to the proposal of urban representatives, the League did not, however, become the supreme arbiter of traffic signs. The article concludes by nuancing a 1931

    OBJECTIVE The aim of this study was to investigate the frequency, magnitude, and distribution of head impacts sustained by players in a junior rugby league over a season of matches. METHODS The authors performed a prospective cohort analysis of impact magnitude, frequency, and distribution on data collected with instrumented XPatches worn behind the ear of players in an "under-11" junior rugby league team (players under 11 years old). RESULTS A total of 1977 impacts were recorded. Over the course of the study, players sustained an average of 116 impacts (average of 13 impacts per player per match). The measured linear acceleration ranged from 10g to 123g (mean 22g, median 16g, and 95th percentile 57g). The rotational acceleration ranged from 89 rad/sec 2 to 22,928 rad/sec 2 (mean 4041 rad/sec 2 , median 2773 rad/sec 2 , and 95th percentile 11,384 rad/sec 2 ). CONCLUSIONS The level of impact severity based on the magnitude of impacts for linear and rotational accelerations recorded was similar to the impacts reported in studies of American junior and high school football, collegiate football, and youth ice hockey players, but the players in the rugby league cohort were younger, had less body mass, and played at a slower speed than the American players. Junior rugby league players are required to tackle the player to the ground and use a different tackle technique than that used in American football, likely increasing the rotational accelerations recorded at the head.

    Based on the monthly temperature and precipitation data of 15 meteorological stations and the statistical data of livestock density in Xilinguole League in 1981-2007, and by using ArcGIS, this paper analyzed the spatial distribution of the climate aridity and livestock density in the League, and in combining with the ten-day data of the normalized difference vegetation index (NDVI) in 1981-2007, the driving factors of the vegetation cover change in the League were discussed. In the study period, there was a satisfactory linear regression relationship between the climate aridity and the vegetation coverage. The NDVI and the livestock density had a favorable binomial regression relationship. With the increase of NDVI, the livestock density increased first and decreased then. The vegetation coverage had a complex linear relationship with livestock density and climate aridity. The NDVI had a positive correlation with climate aridity, but a negative correlation with livestock density. Compared with livestock density, climate aridity had far greater effects on the NDVI.

Injury related symptoms and their impacts on the activity limitation, ability to perform activities of daily living as well participation in sports and recreational activities was obtained through the Knee Outcome Survey (KOS). The results indicated that 31 out of 59 participants reported the history of knee injury. In addition, 18.6%, 22.4% and 81% of the referees reported that they had been injured during the last 6 months of the last year, and at some point in their refereeing careers, respectively. Results further indicated that 48.8% of the injuries occurred in the non-dominant leg and they occurred more frequently during training sessions (52%). Furthermore, the value of KOS was 85 ± 13 for Activities of Daily Living subscale and 90 ± 9 for Sports and Recreational Activities subscale of the KOS. Knee injury was quite common among the Football Premier League professional referees. It was also indicated that the injuries occurred mainly due to insufficient physical fitness. Therefore, it is suggested that football referees undergo the proper warm-up program to avoid knee injury.

    In a sports league such as in a soccer league, the teams’ competition standing is based on a cumulative point system. Typically, the standard point system is given to every single match for win, draw and lose teams is the 3-1-0 point system. In this paper, we explore the effect of changing point systems to teams’ competition standing by changing the weightage values for win, draw and lose teams. Three types of point systems are explored in our soccer simulation model; firstly the 3-1-0, secondly the 2-1-0 and thirdly the 4-1-0 point system. Based on the teams participating in a Malaysian soccer Super League, our simulation result shows that there are small changes in term of teams’ competition standing when we compared the actual rank and the simulation rank position. However, the 4-1-0 point system recorded the highest Pearson correlation value which is 0.97, followed by the 2-1-0 point system (0.95) and thirdly the 3-1-0 point system (0.94).

    Background: The risk of all-cause injury and concussion associated with football is significant. The National Football League (NFL) has implemented changes to increase player safety warranting investigation into the incidence and patterns of injury. Purpose: To document the incidence and patterns of all-cause injury and concussions in the NFL. Study Design: Descriptive epidemiology study. Methods: Injury data were collected prospectively from official NFL injury reports over 2 regular seasons from 2012 to 2014, with identification of injury incidence rates and patterns. Concussion rate ratios were calculated using previously reported NFL rates. Results: A total of 4284 injuries were identified, including 301 concussions. The all-cause injury rate was 395.8 per 1000 athletes at risk (AAR) and concussion incidence was 27.8 per 1000 AAR. Only 2.3% of team games were injury free. Wide receivers, tight ends, and defensive backs had the highest incidence of injury and concussion. Concussion incidence was 1.61-fold higher in 2012 to 2014 compared with 2002 to 2007. The knee was injured most frequently, followed by the ankle, hamstring, shoulder, and head. Conclusion: The incidence of all-cause injury and concussion in the NFL is significant. Concussion injury rates are higher than previous reports, potentially reflecting an improvement in recognition and awareness. Injury prevention efforts should continue to reduce the prevalence of injury associated with football. PMID:26675321

The sample used corresponded to 380 games from the 2008-2009 season of the Spanish Men's Professional League. The game-related statistics gathered were: total shots, shots on goal, effectiveness, assists, crosses, offsides commited and received, corners, ball possession, crosses against, fouls committed and received, corners against, yellow and red cards, and venue. An univariate (t-test and multivariate (discriminant analysis of data was done. The results showed that winning teams had averages that were significantly higher for the following game statistics: total shots (p < 0.001, shots on goal (p < 0.01, effectiveness (p < 0.01, assists (p < 0.01, offsides committed (p < 0.01 and crosses against (p < 0.01. Losing teams had significantly higher averages in the variable crosses (p < 0.01, offsides received (p < 0. 01 and red cards (p < 0.01. Discriminant analysis allowed to conclude the following: the variables that discriminate between winning, drawing and losing teams were the total shots, shots on goal, crosses, crosses against, ball possession and venue. Coaches and players should be aware for these different profiles in order to increase knowledge about game cognitive and motor solicitation and, therefore, to evaluate specificity at the time of practice and game planning

  7. A medley of meanings: Insights from an instance of gameplay in League of Legends

    Full Text Available This article engages with the notion of insightful gameplay. It recounts debates about what, if anything, makes play meaningful. Through these, it contends that while some games are explicitly designed to foster insightful gameplay, most are not and many might even be considered utterly meaningless. It notes how discussions about what makes playing games meaningful raise concomitant questions about what playing means. It then strives to reconcile these two interrelated questions by offering the notion of a medley of meanings. A medley of meanings is the notion that each player brings their own subjective disposition to playing to a particular instance of gameplay; no participant to gameplay should be considered as in a state that is “not playing”. Because these subjective dispositions to playing can be quite divergent, players can and often do clash in instances of gameplay. This article then contends that these clashes can in turn render the most seemingly meaningless games potential hotbeds of insightful gameplay. The second half of this article discusses the ethnographic example of an instance of gameplay in the digital game League of Legends in order to explicate the notion of a medley of meanings.

    Full Text Available The 2D soccer simulation league is one of the best test beds for the research of artificial intelligence (AI. It has achieved great successes in the domain of multi-agent cooperation and machine learning. However, the problem of integral offensive strategy has not been solved because of the dynamic and unpredictable nature of the environment. In this paper, we present a novel offensive strategy based on multi-group ant colony optimization (MACO-OS. The strategy uses the pheromone evaporation mechanism to count the preference value of each attack action in different environments, and saves the values of success rate and preference in an attack information tree in the background. The decision module of the attacker then selects the best attack action according to the preference value. The MACO-OS approach has been successfully implemented in our 2D soccer simulation team in RoboCup competitions. The experimental results have indicated that the agents developed with this strategy, along with related techniques, delivered outstanding performances.

    It is currently unknown how pre-existing lumbar spine conditions may affect the medical evaluation, draft status, and subsequent career performance of National Football League (NFL) players. To determine if a pre-existing lumbar diagnosis affects a player's draft status or his performance and longevity in the NFL. Cohort study; Level 3. The investigators evaluated the written medical evaluations and imaging reports of prospective NFL players from a single franchise during the NFL Scouting Combine from 2003 to 2011. Players with a reported lumbar spine diagnosis and with appropriate imaging were included in this study. Athletes were then matched to control draftees without a lumbar spine diagnosis by age, position, year, and round drafted. Career statistics and performance scores were calculated. Of a total of 2965 athletes evaluated, 414 were identified as having a pre-existing lumbar spine diagnosis. Players without a lumbar spine diagnosis were more likely to be drafted than were those with a diagnosis (80.2% vs. 61.1%, respectively, P study suggest that athletes with pre-existing lumbar spine conditions were less likely to be drafted and that the diagnosis is associated with a decrease in career longevity but not performance. Players with lumbar fusion have achieved successful careers in the NFL. © 2015 The Author(s).

    In 2004, the Australian Football League Central Australia (AFLCA) implemented the Responsible Alcohol Strategy (RAS), which aimed to decrease alcohol consumption at matches, and to promote healthy lifestyle messages to the youth of Central Australia participating in Australian Rules football. The evaluation adopted a pre- and post-implementation design to monitor a number of performance indicators. The evaluation analysed routinely collected data from AFLCA, its Security Company, Alice Springs Police Department and Alice Springs Hospital; we surveyed AFLCA staff, club officials and umpires; and undertook direct observation at AFLCA events. The volume of alcohol sold at matches decreased. Survey data indicate decreased alcohol related violence, improved spectator behaviour and decreased spectator attendances. Police data suggest declining alcohol-related and violent behaviours, but trends were not statistically significant. Alice Springs Hospital injury admission data indicate a non-significant interaction between year and season effect. In a community context of high alcohol consumption and high rates of interpersonal violence, the strategies implemented were successful in decreasing alcohol consumption and related undesirable behaviours at football games. However, these measures have resulted in unintended consequences: decreased numbers of spectators attending games, decreased canteen sales and falling sponsorship. The decreased revenue has raised serious issues about sustainability of the alcohol intervention, and stimulated discussions with government and others about strategies to maintain this important alcohol reduction policy.

    Cloud computing system is a huge cluster of interconnected servers residing in a datacenter and dynamically provisioned to clients on-demand via a front-end interface. Scientific applications scheduling in the cloud computing environment is identified as NP-hard problem due to the dynamic nature of heterogeneous resources. Recently, a number of metaheuristics optimization schemes have been applied to address the challenges of applications scheduling in the cloud system, without much emphasis on the issue of secure global scheduling. In this paper, scientific applications scheduling techniques using the Global League Championship Algorithm (GBLCA) optimization technique is first presented for global task scheduling in the cloud environment. The experiment is carried out using CloudSim simulator. The experimental results show that, the proposed GBLCA technique produced remarkable performance improvement rate on the makespan that ranges between 14.44% to 46.41%. It also shows significant reduction in the time taken to securely schedule applications as parametrically measured in terms of the response time. In view of the experimental results, the proposed technique provides better-quality scheduling solution that is suitable for scientific applications task execution in the Cloud Computing environment than the MinMin, MaxMin, Genetic Algorithm (GA) and Ant Colony Optimization (ACO) scheduling techniques.

    Summary: Currently more solar power plants are built in Germany than ever before. Citizens, farmers, companies, initiatives and local authorities are participating. Solarbundesliga (Solar League), launched in April 2001, offers a forum for these solar minded actors. It ensures that the local commitment of these actors is known all over Germany and in doing so awakens the competitive drive in many people. The Solarbundesliga is organised by Deutsche Umwelthilfe and the specialist journal Solarthemen. It is a very good instrument to show the outcome of the solar energy supply at the local level in media friendly means. The image campaign SolarLokal of the Deutsche Umwelthilfe and SolarWorld, one of the biggest solar companies worldwide, is a very good approach for municipalities to inform their citizens about the benefits of solar energy. According to a recent opinion poll, SolarLokal contributes to an increase in solar current plants in the participating cities and towns. Additionally, it brings craftspeople having experience in installing solar power plants and interested citizens together. So, SolarLokal provides incentives to the local economy. The idea of SolarLokal is transferable to other countries. In January 2006 the partner campaign IsIaSolar was started in Teneriffa. (orig.)

    Shoulder disorders are common in football players, with up to 50% of National Football League (NFL) recruits reporting a history of shoulder injuries. Superior labrum anterior-posterior (SLAP) tears are an entity with well-described detrimental effects on return to play in overhead-throwing athletes but with minimal data in contact athletes. To identify the incidence, predisposing factors, and effect of SLAP tears in NFL athletes and prospects as well as the treatment patterns of NFL team physicians. Descriptive epidemiology study. This study was a comprehensive analysis of SLAP tears in elite football players using a dual approach: (1) SLAP injuries recorded in the NFL Injury Surveillance System from 2000 to 2014 were evaluated by player position, type of play, days/games lost, and surgical intervention; (2) NFL Scouting Combine athletes from 2003 to 2011 with prior SLAP repair were evaluated for draft success, and drafted athletes were compared with matched controls for career length and performance scores. SLAP tears represented a small portion (3.1%) of shoulder injuries in NFL athletes from 2000 to 2014, occurring most commonly in offensive linemen (28%). Surgically treated SLAP tears (42%) resulted in more days missed than did nonoperatively managed tears (140.2 vs 21.5 days; P football players, it is clear that these injuries have the potential to cause significant detriment to an athlete's career.

    The issues of modeling asscoiation football prediction model has become increasingly popular in the last few years and many different approaches of prediction models have been proposed with the point of evaluating the attributes that lead a football team to lose, draw or win the match. There are three types of approaches has been considered for predicting football matches results which include statistical approaches, machine learning approaches and Bayesian approaches. Lately, many studies regarding football prediction models has been produced using Bayesian approaches. This paper proposes a Bayesian Networks (BNs) to predict the results of football matches in term of home win (H), away win (A) and draw (D). The English Premier League (EPL) for three seasons of 2010-2011, 2011-2012 and 2012-2013 has been selected and reviewed. K-fold cross validation has been used for testing the accuracy of prediction model. The required information about the football data is sourced from a legitimate site at http://www.football-data.co.uk. BNs achieved predictive accuracy of 75.09% in average across three seasons. It is hoped that the results could be used as the benchmark output for future research in predicting football matches results.

    The daily distribution of macronutrient intake can modulate aspects of training adaptations, performance and recovery. We therefore assessed the daily distribution of macronutrient intake (as assessed using food diaries supported by the remote food photographic method and 24-hr recalls) of professional soccer players (n = 6) of the English Premier League during a 7-day period consisting of two match days and five training days. On match days, average carbohydrate (CHO) content of the prematch (recovery from an evening kick-off) were similar (p > .05) though such intakes were lower than contemporary guidelines considered optimal for prematch CHO intake and postmatch recovery. On training days, we observed a skewed and hierarchical approach (p lunch (0.6 g·kg -1 )>breakfast (0.3 g·kg -1 )>evening snacks (0.1 g·kg -1 ). We conclude players may benefit from consuming greater amounts of CHO in both the prematch and postmatch meals so as to increase CHO availability and maximize rates of muscle glycogen resynthesis, respectively. Furthermore, attention should also be given to ensuring even daily distribution of protein intake so as to potentially promote components of training adaptation.

    The primary purpose of this investigation was to examine the physiological profile of a National Hockey League (NHL) team over a period of 26 years. All measurements were made at a similar time of year (pre-season) in 703 male (mean age +/- SD = 24 +/- 4 y) hockey players. The data were analyzed across years, between positions (defensemen, forwards, and goaltenders), and between what were deemed successful and non-successful years using a combination of points acquired during the season and play-off success. Most anthropometric (height, mass, and BMI) and physiological parameters (absolute and relative VO2 peak, relative peak 5 s power output, abdominal endurance, and combined grip strength) showed a gradual increase over the 26 year period. Defensemen were taller and heavier, had higher absolute VO2 peak, and had greater combined grip strength than forwards and goaltenders. Forwards were younger and had higher values for relative VO2 peak. Goaltenders were shorter, had less body mass, a higher sum of skinfolds, lower VO2 peak, and better flexibility. The overall pre-season fitness profile was not related to team success. In conclusion, this study revealed that the fitness profile for a professional NHL ice-hockey team exhibited increases in player size and anaerobic and aerobic fitness parameters over a 26 year period that differed by position. However, this evolution of physiological profile did not necessarily translate into team success in this particular NHL franchise.
