    Background In 2002, Hockey Canada changed the age classifications for minor ice hockey. Previously, 10- and 11-year-old children played at the Atom level (no bodychecking), and 12- and 13-year-old children played at the Peewee level (bodychecking allowed). After the policy change, 11-year-old players were placed in the Peewee division with 12-year-old players; the Atom division included 9- and 10-year-old players. The objective of this study was to examine the effect that the policy change had on injuries to 11-year-old players and compare this information with injury trends among 10- and 12-year-old players. Methods The study location was the Capital Health region, which serves the greater Edmonton area in Alberta. Capital Health maintains a database of all emergency department visits in the region. A search of the database identified 10-, 11- and 12-year-old players admitted to 7 emergency departments with hockey-related injuries during the 2 years before and the 2 years after the policy change. We also conducted a chart review for the 11-year-old players, extracting detailed information on the nature and circumstances of their injuries for the same period. Results The rate of injuries sustained by 11-year-old children playing at the Peewee level (with bodychecking) increased significantly compared with the rate among 11-year-0ld players at the Atom level (rate ratio [RR] 1.9, 95% confidence interval [CI] 1.4–2.4). The rate of severe injuries was more than 2 times greater among 11-year-old Peewee players than among 11-year-old Atom players (RR 2.4, 95% CI 1.6–3.6). Injury rates among the 10-year-old players (bodychecking never allowed) and the 12-year-old players (bodychecking always allowed) changed little over the study period. Interpretation The introduction of bodychecking to 11-year-old players was associated with a large increase in injury rates. From a public health perspective, the age at which bodychecking is introduced in minor hockey should be

The purpose of this study is to investigate the trend of reporting hip injuries in amateur ice hockey players in Canada with a focus on injury type and mechanism. Methods: A retrospective review of the Hockey Canada insurance database was performed and data on ice hockey hip injuries reported between January 2005 and June 2011 were collected. The study population included all male hockey players from Peewee (aged 11–12 years to Senior (aged 20+ years participating in amateur level competition sanctioned by Hockey Canada. Reported cases of ice hockey hip injuries were analyzed according to age, mechanism of injury, and injury subtype. Annual injury reporting rates were determined and using a linear regression analysis trended to determine the change in ice hockey hip injury reporting rate over time. Results: One hundred and six cases of ice hockey-related hip injuries were reported in total. The majority of injuries (75.5% occurred in players aged 15–20 years playing at the Junior level. Most injuries were caused by a noncontact mechanism (40.6% and strains were the most common subtype (50.0%. From 2005 to 2010, the number of reported hip injuries increased by 5.31 cases per year and the rate of reported hip injury per 1,000 registered players increased by 0.02 cases annually.

    @@ As one of the oldest of competitive pastimes, the sport of hockey dates back well before the Ancient Olympic Games. In medieval Europe, pictures of men playing a game with hooked1 sticks appear on stained-glass windows2 at both the Canterbury3 and Gloucester4 cathedrals5. It became so popular by the Middle Ages that it was banned6 in England for a time because it interfered with the practice of archery7, which was the basis for national defense. The name hockey probably derives from the French hocquet, or shepherd's crook8 and refers to the crooked9 stick.

    Mentally tough' athletes show resilience and an ability to compete during adverse conditions. The present study investigated mental toughness and assessed causal explanations for positive and negative reactions to imagined events using Seligman's Attributional Style Questionnaire. Pessimistic Explanatory style on this scale is a risk factor for negative affect and behavior following negative events. 38 elite athletes in ice hockey were rated for mental toughness by the National Hockey League's scouts on consensually derived criteria. The comparison of players above and below the median split on mental toughness showed composite explanations for negative events that were more internal, stable and global for players above the median. Contrary to predictions, these results suggest that a Pessimistic Explanatory style may benefit hockey performance. PMID:9885080

    The ``hockey stick'' shaped temperature reconstruction of Mann et al. (1998, 1999) has been widely applied. However it has not been previously noted in print that, prior to their principal components (PCs) analysis on tree ring networks, they carried out an unusual data transformation which strongly affects the resulting PCs. Their method, when tested on persistent red noise, nearly always produces a hockey stick shaped first principal component (PC1) and overstates the first eigenvalue. In the controversial 15th century period, the MBH98 method effectively selects only one species (bristlecone pine) into the critical North American PC1, making it implausible to describe it as the ``dominant pattern of variance''. Through Monte Carlo analysis, we show that MBH98 benchmarks for significance of the Reduction of Error (RE) statistic are substantially under-stated and, using a range of cross-validation statistics, we show that the MBH98 15th century reconstruction lacks statistical significance.

    Okuma, Kenji; Little, James J.; Lowe, David

    2003-12-01

    Computer systems that have the capability of analyzing complex and dynamic scenes play an essential role in video annotation. Scenes can be complex in such a way that there are many cluttered objects with different colors, shapes and sizes, and can be dynamic with multiple interacting moving objects and a constantly changing background. In reality, there are many scenes that are complex, dynamic, and challenging enough for computers to describe. These scenes include games of sports, air traffic, car traffic, street intersections, and cloud transformations. Our research is about the challenge of inventing a descriptive computer system that analyzes scenes of hockey games where multiple moving players interact with each other on a constantly moving background due to camera motions. Ultimately, such a computer system should be able to acquire reliable data by extracting the players" motion as their trajectories, querying them by analyzing the descriptive information of data, and predict the motions of some hockey players based on the result of the query. Among these three major aspects of the system, we primarily focus on visual information of the scenes, that is, how to automatically acquire motion trajectories of hockey players from video. More accurately, we automatically analyze the hockey scenes by estimating parameters (i.e., pan, tilt, and zoom) of the broadcast cameras, tracking hockey players in those scenes, and constructing a visual description of the data by displaying trajectories of those players. Many technical problems in vision such as fast and unpredictable players' motions and rapid camera motions make our challenge worth tackling. To the best of our knowledge, there have not been any automatic video annotation systems for hockey developed in the past. Although there are many obstacles to overcome, our efforts and accomplishments would hopefully establish the infrastructure of the automatic hockey annotation system and become a milestone for

    Ulnar artery thrombosis and hypothenar hammer syndrome are rare vascular complications that could potentially occur with repeated blows or trauma to the hand. Although initially reported as an occupational hazard among laborers and craftsmen, it has been observed more recently among recreationalists and athletes. Until now, it has never been reported as a complication in ice hockey players. In this case report, a 26-year-old Canadian professional ice hockey player presented with acute dominant right hand paleness, coolness, and pain with hand use. The patient used a wooden hockey stick with a large knob of tape at the end of the handle, which he regularly gripped in the palm of his right hand to help with face-offs and general stick-handling. Sonographic evaluation demonstrated no arterial flow in the distal right ulnar artery distribution, and ulnar artery occlusion with no aneurysmal degeneration was confirmed by magnetic resonance angiogram. Intraarterial thrombolytic therapy was initiated, and subsequent serial angiograms demonstrated significant improvement in distal ulnar artery flow as well as recanalization of right hand deep palmar arch and digital arteries. The patient's symptoms resolved, and he was maintained on therapeutic anticoagulation for 3 months prior to returning to playing ice hockey professionally, but with a padded glove and no tape knob at the handle tip. This case highlights a unique presentation of hockey stick-handling causing ulnar artery thrombosis that was likely from repeated palmar hypothenar trauma. Appropriate diagnostic imaging, early intraarterial thrombolysis, and postoperative surveillance and follow-up were crucial for the successful outcome in this patient. PMID:23988538

    The aims of this study were to use functional magnetic resonance imaging to examine the neural bases for perceptual-cognitive superiority in a hockey anticipation task. Thirty participants (15 hockey players, 15 non-hockey players) lay in an MRI scanner while performing a video-based task in which they predicted the direction of an oncoming shot in either a hockey or a badminton scenario. Video clips were temporally occluded either 160 ms before the shot was made or 60 ms after the ball/shuttle left the stick/racquet. Behavioral data showed a significant hockey expertise×video-type interaction in which hockey experts were superior to novices with hockey clips but there were no significant differences with badminton clips. The imaging data on the other hand showed a significant main effect of hockey expertise and of video type (hockey vs. badminton), but the expertise×video-type interaction did not survive either a whole-brain or a small-volume correction for multiple comparisons. Further analysis of the expertise main effect revealed that when watching hockey clips, experts showed greater activation in the rostral inferior parietal lobule, which has been associated with an action observation network, and greater activation than novices in Brodmann areas 17 and 18 and middle frontal gyrus when watching badminton videos. The results provide partial support both for domain-specific and domain-general expertise effects in an action anticipation task. PMID:26674059

    2015-11-01

    Ice hockey is a physiologically complex sport requiring aerobic and anaerobic energy metabolism. College and professional teams often test aerobic fitness; however, there is a paucity of information regarding aerobic fitness of elite youth players. Without this knowledge, training of youth athletes to meet the standards of older age groups and higher levels of hockey may be random, inefficient, and or effective. Therefore, the purpose of this study was to determine the aerobic fitness of elite youth hockey players. A retrospective database review was performed for 200 male AAA hockey players between the ages of 13 and 17 (age, 14.4 ± 1.2 years; height, 174.3 ± 8.5 cm; body mass, 67.2 ± 11.5 kg; body fat, 9.8 ± 3.5%) before the 2012-13 season. All subjects performed a graded exercise test on a cycle ergometer, whereas expired air was collected by either a Parvo Medics TrueOne 2400 or a CareFusion Oxycon Mobile metabolic cart to determine maximal oxygen consumption (V[Combining Dot Above]O2max). Body mass, absolute V[Combining Dot Above]O2max, and the power output achieved during the last completed stage increased in successive age groups from age 13 to 15 years (p ≤ 0.05). Ventilatory threshold (VT) expressed as a percentage of V[Combining Dot Above]O2max and the heart rate (HR) at which VT occurred decreased between the ages of 13 and 14 years (p ≤ 0.05), whereas the V[Combining Dot Above]O2 at which VT occurred increased from the age of 14-15 years. There were no changes in relative V[Combining Dot Above]O2max or HRmax between any successive age groups. The aerobic fitness levels of elite youth ice hockey players increased as players age and mature physically and physiologically. However, aerobic fitness increased to a lesser extent at older ages. This information has the potential to influence off-season training and maximize the aerobic fitness of elite amateur hockey players, so that these players can meet standards set by advanced elite age groups.

The model predicts that given sufficient time to adjust: 1) wages, and labor’s share of the distribution of earnings, will increase; 2) labor’s job performance will become a more important determinant of wages; and 3) the personalities of wage negotiators will become less important. The empirical setting is professional hockey. Beginning in...

    2011-01-01

    We examine the relationship between attendance, uncertainty of outcome, and team quality in the National Hockey League. Based on results from a reduced form model of attendance at 6054 regular season NHL games from 2005/06 to 2009/10, we find evidence that attendance increases when fans expect the home team to win by a large margin. Attendance increases for home team underdogs, but the extent of that boost declines as the underdog status worsens. An asymmetric relationship exists between expe...

    2012-12-01

    Sports analysts live in a world of dynamic games flattened into tables of numbers, divorced from the rinks, pitches, and courts where they were generated. Currently, these professional analysts use R, Stata, SAS, and other statistical software packages for uncovering insights from game data. Quantitative sports consultants seek a competitive advantage both for their clients and for themselves as analytics becomes increasingly valued by teams, clubs, and squads. In order for the information visualization community to support the members of this blossoming industry, it must recognize where and how visualization can enhance the existing analytical workflow. In this paper, we identify three primary stages of today's sports analyst's routine where visualization can be beneficially integrated: 1) exploring a dataspace; 2) sharing hypotheses with internal colleagues; and 3) communicating findings to stakeholders.Working closely with professional ice hockey analysts, we designed and built SnapShot, a system to integrate visualization into the hockey intelligence gathering process. SnapShot employs a variety of information visualization techniques to display shot data, yet given the importance of a specific hockey statistic, shot length, we introduce a technique, the radial heat map. Through a user study, we received encouraging feedback from several professional analysts, both independent consultants and professional team personnel.

    Full Text Available Background: This study was carried out to determine whether a preseason vision training program would improve visual skills and season success in a Division I men’s ice hockey team. Methods: A six-week vision training program was implemented with the Ferris State University Men’s Ice Hockey team during their pre-season workouts. Vision training incorporated binocular and accommodative training along with dynamic visual skills training. Results: The study showed an improvement in base out vergence ranges, binocular accommodative facility, and Wayne Saccadic Fixator (WSF scores and was viewed by players to have made a positive impact on their individual performance. The pre- and post vision training goals, shots on goal, and shooting percentage all significantly improved following training. Conclusion: The vision training program during preseason workouts had a positive impact on the players’ visual skills important for hockey. The players’ perception of their vision and how they were using their vision during competitive play also showed a significant change. The majority of the players felt that vision training was an effective use of their practice time allotted by the NCAA.

    A volunteer sample of 50 competitive field hockey players completed the Coopersmith Self-esteem Inventory at pre- and postseason and prospectively collected injury data over a 20-wk. season. Multiple regression analysis showed no relationship between scores on Self-esteem and the number of injuries, the participation time affected due to injury, and sex of players. Further multiple regression analysis showed that frequency of the more severe injuries significantly predicted scores on Self-esteem. This finding can be interpreted as evidence of the relationship between low self-esteem and injury in sport. PMID:9760670

    Full Text Available Background: Although much is known about risk for athletic injury, research on the roles of individual differences in personality and temperament on athletic injury has lagged. We hypothesized that professional athletes with high sensation-seeking and extraversion scores, and with low effortful control scores, would experience more injuries over the course of a season, would have more severe injuries, and would miss more total days of play. Methods: Prospective design with questionnaire report at time one and injury tracking throughout an 18-week athletic season. Setting: Professional hockey team in the United States. Participants: Eighteen professional hockey players (ages 21-33. Measurements: Players completed self-report personality (Sensation-Seeking Scale, Form V and temperament (the Adult Temperament Questionnaire measures. Quantity and severity of injury, as well as playing time missed, were tracked for 18 weeks. Results: On average, players experienced almost 6 injuries causing a loss of 10 playing days through the season. Those players scoring high on Boredom Susceptibility and Total Sensation-Seeking incurred more total injuries. Those scoring high on temperamental neutral perceptual sensitivity suffered more severe injuries. Conclusions: Athletes who suffered more injuries reported a preference for stimulating environments and boredom with non-stimulating environments. Injury severity was not correlated with sensation-seeking but was related to temperamental perceptual sensitivity. Implications for identification of injury-prone athletes, pre-injury training, and post-injury treatment are discussed.

    Full Text Available Abstract Background Ice hockey is an international sport. Injuries occur in a full body fashion, to a number of tissues, commonly through body contact. There is a lack of literature documenting the scope of sports chiropractic practice. Thus, it was the aim to document the type, scope and severity of conditions presenting to, and the treatment provided by, the New Zealand team chiropractor acting as a primary health provider for the duration of the 2007 World Ice Hockey Championships. Methods All conditions presenting were recorded. Diagnosis was recorded along with clinical parameters of injury: injury type, severity, mechanism and whether referral or advanced imaging was required. All treatment provided was continuously recorded, including information on the number of treatments required and the reason, duration, type and location of treatment. Results Players presented for diagnosis of injury 50 times. Muscle (34%, joint (24% and tendon injuries (18% were most common. Players presented with a new injury 76% of the time. Most injuries had been present for less than one week (84%, with 53% occurring through a contact mechanism. Injuries were common at training and match locations. Only two injuries required the player to stop playing or training, both of which were referred for advanced imaging. During the study, 134 treatment consultations were rendered to 45 player injuries. Eighty per-cent of injuries were managed with four or less treatments. Three quarters of treatment was provided at training locations with treatment duration predominantly being between 11-15 minutes (71% and 16-20 minutes (27%. Most treatment delivered was passive in nature (71% although combination active and passive care was provided (27%. Treatment typically involved joint (81% and soft tissue based therapies (81% and was delivered in a full body manner. Conclusions This study documented the injury profile of ice hockey at an international level of competition. It

    2014-01-01

    Full Text Available Hemoptysis can be a very concerning symptom, and the workup of a patient with hemoptysis may be expensive and invasive. Over the past decade, there has been increasing recognition of hemoptysis that occurs in highly trained athletes under conditions of extreme physical exertion and is explained by “pulmonary capillary stress failure”. This report highlights the physiological mechanisms of pulmonary capillary stress failure in the highly trained athlete, with emphasis on the predisposition to develop this condition in underwater sports. We describe the case of an otherwise healthy 34 year-old competitive underwater hockey player who reported hemoptysis following particularly strenuous games. We postulate that the hemoptysis was a result of the pulmonary capillary stress failure caused by the cumulative hemodynamic effects of a markedly elevated cardiac output, the increased central blood volume caused by the hydrostatic effects of submersion in water, and the negative intrathoracic pressure produced by voluntary diaphragmatic contractions.

    Jakeman, JR, McMullan, J, and Babraj, JA. Efficacy of a four-week uphill sprint training intervention in field hockey players. J Strength Cond Res 30(10): 2761-2766, 2016-Current evidence increasingly suggests that very short, supramaximal bouts of exercise can have significant health and performance benefits. Most research conducted in the area, however, uses laboratory-based protocols, which can lack ecological validity. The purpose of this study was to examine the effects of a high-intensity sprint training program on hockey-related performance measures. Fourteen semiprofessional hockey players either completed a 4-week high-intensity training (HIT) intervention, consisting of a total of 6 sessions of HIT, which progressively increased in volume (n = 7), or followed their normal training program (Con; n = 7). Straight-line sprint speed, with and without a hockey stick and ball, and slalom sprint speed, with and without a hockey stick and ball, were used as performance indicators. Maximal sprint speed over 22.9 m was also assessed. On completion of the 4-week intervention, straight-line sprint speed improved significantly in the HIT group (∼3%), with no changes in performance for the Con group. Slalom sprint speed, both with and without a hockey ball, was not significantly different after the training program in either group. Maximal sprint speed improved significantly (12.1%) in the HIT group, but there was no significant performance change in the Con group. The findings of this study indicate that a short period of HIT can significantly improve hockey-related performance measures and could be beneficial to athletes and coaches in field settings.

    Full Text Available The purpose of this study was to determine ice-hockey players’ playing intensity based on their heart rates (HRs recorded during a game and on the outcomes of an incremental maximum oxygen uptake test. Twenty ice-hockey players, members of the Polish junior national team (U18, performed an incremental test to assess their maximal oxygen uptake (V̇ O2max in the two week’s period preceding 5 games they played at the World Championships. Players’ HRs at the first and second ventilatory thresholds obtained during the test were utilized to determine intensity zones (low, moderate, and high that were subsequently used to classify HR values recorded during each of the games. For individual intensity zones, the following HRs expressed as mean values and as percentages of the maximal heart rate (HRmax were obtained: forwards 148-158 b⋅min-1 (79.5-84.8% HRmax, 159-178 b⋅min-1 (85.4-95.6% HRmax, 179-186 b⋅min-1 (96.1-100.0% HRmax; defensemen 149-153 b⋅min-1 (80.0-82.1% HRmax, 154-175 b⋅min-1 (82.6- 94.0% HRmax, 176-186 b⋅min-1 (94.5-100.0% HRmax. The amount of time the forwards and defensemen spent in the three intensity zones expressed as percentages of the total time of the game were: 54.91 vs. 55.62% (low, 26.40 vs. 22.38% (moderate and 18.68 vs. 22.00% (high. The forwards spent more time in the low intensity zone than the defensemen, however, the difference was not statistically significant. The results of the study indicate that using aerobic and anaerobic metabolism variables to determine intensity zones can significantly improve the reliability of evaluation of the physiological demands of the game, and can be a useful tool for coaches in managing the training process.

    Full Text Available When it comes to beautiful visual rendering and games on the Android handsets that we use today, much of that credit has to be given to the various graphic libraries which come along with programming paradigms. Just like anything in programming and technology, there are good and bad ways to implement and get certain things done both at the front end and the backend. What the Android Native Development Kit (NDK does is that it works alongside the Software Development Kit (SDK and injects the native powers of any C/C++ application into your Android application which can be packaged as any normal application and run on an emulator/device of choice. The SDK, the NDK, the ADT and Eclipse are primarily what one requires to directly hit on towards Android Native Development. So now how does one enjoy the seamless graphics, multimedia, physics and games on an Android device? It is the Native API’s which come as a result of relying on performance critical native code which makes this possible. In this paper we develop a basis game of Air Hockey, which is more of a concept game made using the technological paradigm of the NDK in Android Programming. Right from defining the structure of the table up to defining and implementing the shaders and 3D rendering, almost every important aspect has been researched and put into working through this paper.

    Full Text Available Purpose: The purpose of this study was to investigate the differences in ankle flexibility and skating technique between a traditional hockey skate boot and a hockey skate boot with a flexible rear tendon guard. Skating technique was further investigated at different speeds to give insight on how skating technique alters as skating speed is increased. Methods: Eight elite hockey players were selected for the present study, which was conducted while skating on an Endless Ice Skating Treadmill.  Variables were recorded using a three-camera setup and measured from video records at five selected treadmill speeds using the Dartfish Team Pro v6 software.  Kinematic variables were then compared between the two skate designs with a doubly multivariate repeated measures design.  Statistical significance was set at p<0.05.  Results: Post hoc univariate tests comparing skate designs displayed significant increases in plantar flexion, plantar flexion angular velocity, hip extension, hip extension angular velocity, stride length, and stride velocity while participants were wearing the skates that had a flexible rear tendon guard.  Significant increases were also displayed in plantar flexion, plantar flexion angular velocity, knee extension, knee extension angular velocity, hip extension, hip extension angular velocity, hip abduction range of motion, hip abduction angular velocity, stride width, stride length, and stride velocity as the treadmill speed increased. There was also a significant decrease in the time the skate was in contact with the treadmill as treadmill speed increased. Conclusion: The results suggested that while skating forward, hockey players could improve their hockey skating technique by using hockey skates that have a flexible rear tendon guard.  This flexible tendon guard improved skating technique by increasing the time of force application to the ice by increasing the range of ankle plantar flexion during propulsion of the

    We report a case of ultrasound-guided infraorbital nerve block with a hockey stick typed probe in plane approach. Individual difference of infraorbital anatomy makes it difficult to puncture the infraorbital for a man, and the risks include bleeding, double vision and paranasal sinus puncture. The advantage of ultrasound-guided nerve block has been reported. Compared with conventional land mark method approach, ultrasound technique is thought to be easy to perform, more quickly and safely without any complications. From our results, we have demonstrated that ultrasound-guided infraorbital nerve block assisted by hockey stick typed probe could become one of the safe methods for this purpose. PMID:24228458

    Depolarized reflected light microscopy and high resolution optical reflectivity measurements have been conducted on free-standing films of an achiral four-ring hockey stick shaped liquid crystal exhibiting SmA-B2-SmX* transition sequence. A layer thinning transition above the bulk isotropic-SmA phase transition has been observed. This behaviour was highly irreproducible, indicating an irregular layer thinning transition. From optical reflectivity data, both thickness of the free-standing films and the smectic interlayer spacing were determined. This is the first report of the layer thinning transition in a hockey stick shaped liquid crystal.

    Ice sledge hockey is a popular paralympic team sport where players rely entirely on their upper body to propel themselves rapidly across the ice surface. The isolated and repetitive poling movements provide a good model for examining upper-body sprint ability and the related movement and strength characteristics. Therefore, the purpose of the present study was to investigate the relationship between upper-body maximal strength, power, and sprint performance in ice sledge hockey. Thirteen male ice sledge hockey players from the Norwegian national team performed three 30-m maximal sprint tests recorded by fixed light sensors. The best 30-m time for each subject was used for further analyses, and the sprint was analyzed more in detail for the first and last 10-m split times and kinematics (cycle length and rate) using photocells and 2-dimensional video analysis. One repetition maximum (1RM) strength and peak power were assessed in the bench press, bench pull, and pull-down exercises using a barbell and a linear encoder. Both 1RM strength and peak power for all the 3 strength exercises correlated significantly with the total sprint time (-0.75 sprint test. There were no significant relationships between sprint kinematics and 1RM strength and peak power. Overall, these results demonstrate that there are close relationships between upper-body strength, power, and sprint performance in highly trained athletes and that the ability to produce propulsion and high frequency in combination is important for the sprint abilities in ice sledge hockey.

    This study aimed to compare knee joint position sense of roller hockey players with an age-matched group of non-athletes. Forty-three male participants voluntarily participated in this cross-sectional study: 21 roller hockey players (mean age: 23.2 ± 4.2 years old, mean weight: 81.8 ± 9.8 kg, mean height: 180.5 ± 4.1 cm) and 22 age-matched non-athletes (mean age: 23.7 ± 3.9 years old, mean weight: 85.0 ± 6.2 kg, mean height: 181.5 ± 5.0 cm). Knee joint position sense of the dominant limb was evaluated using a technique of open-kinetic chain and active knee positioning. Joint position sense was reported using absolute, relative and variable angular errors. The main results indicated that the group of roller hockey players showed significantly lower absolute (2.4 ± 1.2º vs. 6.5 ± 3.2º, p ≤ 0.001) and relative (1.7 ± 2.1º vs. 5.8 ± 4.4º, p ≤ 0.001) angular errors in comparison with the non-athletes group. In conclusion, the results from this present study suggest that proprioceptive acuity, assessed by measuring joint position sense, is increased in roller hockey players. The enhanced proprioception of the roller hockey players could contribute to injury prevention and improved performance during sporting activities. PMID:27111126

    The onset of melatonin secretion in the evening is the most reliable and most widely used index of circadian timing in humans. Saliva (or plasma) is usually sampled every 0.5-1 hours under dim-light conditions in the evening 5-6 hours before usual bedtime to assess the dim-light melatonin onset (DLMO). For many years, attempts have been made to find a reliable objective determination of melatonin onset time either by fixed or dynamic threshold approaches. The here-developed hockey-stick algorithm, used as an interactive computer-based approach, fits the evening melatonin profile by a piecewise linear-parabolic function represented as a straight line switching to the branch of a parabola. The switch point is considered to reliably estimate melatonin rise time. We applied the hockey-stick method to 109 half-hourly melatonin profiles to assess the DLMOs and compared these estimates to visual ratings from three experts in the field. The DLMOs of 103 profiles were considered to be clearly quantifiable. The hockey-stick DLMO estimates were on average 4 minutes earlier than the experts' estimates, with a range of -27 to +13 minutes; in 47% of the cases the difference fell within ±5 minutes, in 98% within -20 to +13 minutes. The raters' and hockey-stick estimates showed poor accordance with DLMOs defined by threshold methods. Thus, the hockey-stick algorithm is a reliable objective method to estimate melatonin rise time, which does not depend on a threshold value and is free from errors arising from differences in subjective circadian phase estimates. The method is available as a computerized program that can be easily used in research settings and clinical practice either for salivary or plasma melatonin values. PMID:24224578

    Due to the fast and physical nature of the game, prevention of injuries is an important issue in ice hockey. The injuries of the German male senior and junior (U16, U17, U18, U19, U20) national ice hockey teams were documented and analyzed in 1006 games between 1986 and 2006. This unique long observation period over 20 years, as well as the standardized protocol of documentation provides reliable data concerning injury pattern in German international ice hockey. Overall 277 injuries were recorded. Comparing the first and the last ten years of observation, the number did not decline over the time, despite various national and international efforts of injury prevention. The majority of the injuries, almost 60%, were caused by body contact with increasing tendency. Remarkably, the injuries with no body or puck/stick contact more than doubled in the last ten years compared to the first ten years of observation. Most injuries happened to the extremities with decreasing tendency to lower body and increasing tendency to upper body injuries. The number of head injuries did not change significantly. More injuries occurred in the second and third period compared to the first period of the game. The data of this study indicate that many injuries might be due to insufficient physical condition with consecutive lack of concentration and coordination. Players do not seem to meet the increasing technical and athletic requirements of international ice-hockey. The increasing speed and physical energy in international ice-hockey make the game unique and fascinating. Therefore, the aim must be to decrease the number and above all the severity of injuries by further development and adjustment of the player's equipment. Also, a better cooperation of players, coaches, sports medicine and referees seems to be necessary for injury prevention in the future. PMID:20517801

    The aim of this investigation was to determine the efficacy of a caffeine-containing energy drink to improve physical performance of elite field hockey players during a game. On 2 days separated by a week, 13 elite field hockey players (age and body mass = 23.2 ± 3.9 years and 76.1 ± 6.1 kg) ingested 3 mg of caffeine per kg of body mass in the form of an energy drink or the same drink without caffeine (placebo drink). After 60 min for caffeine absorption, participants played a simulated field hockey game (2 × 25 min). Individual running pace and instantaneous speed during the game were assessed using GPS devices. The total number of accelerations and decelerations was determined by accelerometry. Compared with the placebo drink, the caffeinated energy drink did not modify the total distance covered during the game (6,035 ± 451 m and 6,055 ± 499 m, respectively; p = .87), average heart rate (155 ± 13 beats per min and 158 ± 18 beats per min, respectively; p = .46), or the number of accelerations and decelerations (697 ± 285 and 618 ± 221, respectively; p = .15). However, the caffeinated energy drink reduced the distance covered at moderate-intensity running (793 ± 135 and 712 ± 116, respectively; p = .03) and increased the distance covered at high-intensity running (303 ± 67 m and 358 ± 117 m; p = .05) and sprinting (85 ± 41 m and 117 ± 55 m, respectively; p = .02). Elite field hockey players can benefit from ingesting caffeinated energy drinks because they increase the running distance covered at high-intensity running and sprinting. Increased running distance at high speed might represent a meaningful advantage for field hockey performance.

  17. Minority Games

    International Nuclear Information System (INIS)

    New branches of scientific disciplines often have a few paradigmatic models that serve as a testing ground for theories and a starting point for new inquiries. In the late 1990s, one of these models found fertile ground in the growing field of econophysics: the Minority Game (MG), a model for speculative markets that combined conceptual simplicity with interesting emergent behaviour and challenging mathematics. The two basic ingredients were the minority mechanism (a large number of players have to choose one of two alternatives in each round, and the minority wins) and limited rationality (each player has a small set of decision rules, and chooses the more successful ones). Combining these, one observes a phase transition between a crowded and an inefficient market phase, fat-tailed price distributions at the transition, and many other nontrivial effects. Now, seven years after the first paper, three of the key players-Damien Challet, Matteo Marsili and Yi-Cheng Zhang-have published a monograph that summarizes the current state of the science. The book consists of two parts: a 100-page overview of the various aspects of the MG, and reprints of many essential papers. The first chapters of Part I give a well-written description of the motivation and the history behind the MG, and then go into the phenomenology and the mathematical treatment of the model. The authors emphasize the 'physics' underlying the behaviour and give coherent, intuitive explanations that are difficult to extract from the original papers. The mathematics is outlined, but calculations are not carried out in great detail (maybe they could have been included in an appendix). Chapter 4 then discusses how and why the MG is a model for speculative markets, how it can be modified to give a closer fit to observed market statistics (in particular, reproducing the 'stylized facts' of fat-tailed distributions and volatility clustering), and what conclusions one can draw from the behaviour of the MG when

    2014-01-01

    Objectives: Several recent high profile injuries to elite players in the National Hockey League (NHL) secondary to skate blade lacerations have generated significant interest in these injuries and possible methods to protect against them. These injuries are typically due to direct contact of the skate blade of another player with posterior aspect of the calf resulting in a range of potential injuries to tendons or neurovascular structures. The Achilles tendon is most commonly involved. Kevlar® reinforced socks have recently become available for hockey players to wear and are cited as providing possible protection against such injuries. However, there has been no investigation of the possible protective effects of Kevlar® reinforced socks against skate blade injuries, and it is currently unknown what protective effects, if any, that these socks provide against these injuries. The proposed study sought to address this by conducting a biomechanical investigation of the protective effects of Kevlar® reinforced socks against Achilles tendon injuries in a simulated model of skate blade injury using human cadaver limbs. This novel investigation is the first to address the possible benefits to hockey players of wearing Kevlar® reinforced socks. Methods: Seven matched pairs of human cadaver lower limbs were fitted with a Kevlar ® reinforced sock comprised of 60% Kevlar®/20% Coolmax® polyester/18 % Nylon/12% Spandex (Bauer Elite Performance Skate Sock) on one limb and a standard synthetic sock comprised of 51% polyester/47% nylon/2% spandex (Bauer Premium Performance Skate Sock) on the contralateral limb as a control. Each limb was then mounted on a Materials Testing System (MTS) with the ankle dorsiflexed to 90° and the knee held in full extension using a custom designed jig. Specimens were then impacted with a hockey skate blade directed at the posterior calf, 12 cm above the heel, at an angle of 45° and a speed of 31m/s, to a penetration depth of 4.3 cm, to

    Isolated cuneiform fractures are rare and are often missed on plain radiographs, leading to delayed diagnosis and delayed return to sport. The authors of this study present a 32-year-old male ice hockey player who sustained trauma to his dorsal midfoot from a slap shot. Radiographs were negative for fracture. After inability to wean out of the controlled ankle movement boot, magnetic resonance imaging was ordered, demonstrating a middle cuneiform fracture. The patient was seen in physical therapy, where aquatic therapy, strength training, and cardiovascular conditioning were progressed. He was able to wean out of the controlled ankle movement boot at 7 weeks after injury and return to playing ice hockey. Here, we outline rehabilitation and a diagnostic and rehabilitative algorithm for those who sustain trauma to the dorsal midfoot with suspected fracture. PMID:26945214

    Full Text Available The frequency and potential long-term effects of sport-related traumatic brain injuries (TBI make it a major public health concern. The culture within contact sports, such as ice hockey, encourages aggression that puts youth at risk of TBI such as concussion. Newspaper reports play an important role in conveying and shaping the culture around health-related behaviors. We qualitatively studied reports about sport-related TBI in four major North American newspapers over the last quarter-century. We used the grounded-theory approach to identify major themes and then did a content analysis to compare the frequency of key themes between 1998-2000 and 2009-2011. The major themes were: perceptions of brain injury, aggression, equipment, rules and regulations, and youth hockey. Across the full study period, newspaper articles from Canada and America portrayed violence and aggression that leads to TBI both as integral to hockey and as an unavoidable risk associated with playing the game. They also condemned violence in ice hockey, criticized the administrative response to TBI, and recognized the significance of TBI. In Canada, aggression was reported more often recently and there was a distinctive shift in portraying protective equipment as a solution to TBI in earlier years to a potential contributing factor to TBI later in the study period. American newspapers gave a greater attention to 'perception of risks' and the role of protective equipment, and discussed TBI in a broader context in the recent time period. Newspapers from both countries showed similar recent trends in regards to a need for rule changes to curb youth sport-related TBI. This study provides a rich description of the reporting around TBI in contact sport. Understanding this reporting is important for evaluating whether the dangers of sport-related TBI are being appropriately communicated by the media.

J Strength Cond Res 30(8): 2122-2128, 2016-The purpose of this study was to quantify energy expenditure and heart rate data for Division I female field hockey players during competitive play. Ten female Division I collegiate field hockey athletes (19.8 ± 1.6 years; 166.4 ± 6.1 cm; 58.2 ± 5.3 kg) completed the Yo-Yo intermittent endurance test to determine maximal heart rate. One week later, all subjects wore a heart rate monitor during a series of 3 matches in an off-season competition. Average heart rate (AvHR), average percentage of maximal heart rate (AvHR%), peak exercise heart rate (PExHR), and percentage of maximal heart rate (PExHR%), time spent in each of the predetermined heart rate zones, and caloric expenditure per minute of exercise (kcalM) were determined for all players. Differences between positions (backs, midfielders, and forwards) were assessed. No significant differences in AvHR, AvHR%, PExHR, PExHR%, and %TM were observed between playing positions. The AvHR% and PExHR% for each position fell into zones 4 (77-93% HRmax) and 5 (>93% HRmax), respectively, and significantly more time was spent in zone 4 compared with zones 1, 2, 3, and 5 across all players (p ≤ 0.05). The kcalM reflected very heavy intensity exercise. The results of this study will contribute toward understanding the sport-specific physiological demands of women's field hockey and has specific implications for the duration and schedule of training regimens.

    Skating is a fundamental movement in ice hockey; however little research has been conducted within the field of hockey skating biomechanics due to the difficulties of on-ice data collection. In this study a novel on-ice measurement approach was tested for reliability, and subsequently implemented to investigate the forward skating technique, as well as technique differences across skill levels. Nine high caliber (High) and nine low caliber (Low) hockey players performed 30 m forward skating trials. A 3D accelerometer was mounted to the right skate for the purpose of stride detection, with the 2nd and 6th strides defined as acceleration and steady-state, respectively. The activity of five lower extremity muscles was recorded using surface electromyography. Biaxial electro-goniometers were used to quantify hip and knee angles, and in-skate plantar force was measured using instrumented insoles. Reliability was assessed with the coefficient of multiple correlation, which demonstrated moderate (r>0.65) to excellent (r>0.95) scores across selected measured variables. Greater plantar-flexor muscle activity and hip extension were evident during acceleration strides, while steady state strides exhibited greater knee extensor activity and hip abduction range of motion (p<0.05). High caliber exhibited greater hip range of motion and forefoot force application (p<0.05). The successful implementation of this on-ice mobile measurement approach offers potential for athlete monitoring, biofeedback and training advice.

    The penalty corner is one of the most important goal plays in field hockey. The drag-flick is used less by women than men in a penalty corner. The aim of this study was to describe training-induced changes in the drag-flick technique in female field hockey players. Four female players participated in the study. The VICON optoelectronic system (Oxford Metrics, Oxford, UK) measured the kinematic parameters of the drag-flick with six cameras sampling at 250 Hz, prior to and after training. Fifteen shots were captured for each subject. A Wilcoxon test assessed the differences between pre-training and post-training parameters. Two players received specific training twice a week for 8 weeks; the other two players did not train. The proposed drills improved the position of the stick at the beginning of the shot (p < 0.05), the total distance of the shot (p < 0.05) and the rotation radius at ball release (p < 0.01). It was noted that all players had lost speed of the previous run. Further studies should include a larger sample, in order to provide more information on field hockey performance. PMID:24868116

    The objective of this study was to describe the effect of concussion on upper and lower body strength in children and youth athletes. The participant group was made up of 178 unique male and female ice hockey players (ages 8-14 years). Using a 3-year prospective longitudinal research design, baseline and post-concussion data on hand grip strength, jump tests, and leg maximal voluntary contraction were collected. Using a linear mixed-effects model, no significant differences were found when comparing the baseline strength performance of individuals who went on to experience a concussion and those who did not. When accounting for sex, multiple concussions, and ongoing changes in strength associated with age, weaker hand grip scores were found following concussion while participants were still symptomatic. Lower squat jump heights were achieved while participants were symptomatic as well as when they were no longer self-reporting symptoms associated with concussion. This study represents an initial step towards better understanding strength performance following concussion that may limit the on and off ice performance of youth ice hockey players, as well as predispose youth to subsequent injuries.

    2011-03-01

    The purpose of this study was to identify joint angular kinematics that corresponds to shooting accuracy in the stationary ice hockey wrist shot. Twenty-four subjects participated in this study, each performing 10 successful shots on four shooting targets. An eight-camera infra-red motion capture system (240 Hz), along with passive reflective markers, was used to record motion of the joints, hockey stick, and puck throughout the performance of the wrist shot. A multiple regression analysis was carried out to examine whole-body kinematic variables with accuracy scores as the dependent variable. Significant accuracy predictors were identified in the lower limbs, torso and upper limbs. Interpretation of the kinematics suggests that characteristics such as a better stability of the base of support, momentum cancellation, proper trunk orientation and a more dynamic control of the lead arm throughout the wrist shot movement are presented as predictors for the accuracy outcome. These findings are substantial as they not only provide a framework for further analysis of motor control strategies using tools for accurate projection of objects, but more tangibly they may provide a comprehensive evidence-based guide to coaches and athletes for planned training to improve performance.

  16. Bidirectional reflectance spectroscopy 7. The single particle phase function hockey stick relation

    Hapke, Bruce

    2012-11-01

    The measured volume-average single particle angular scattering functions of a large number of types of particle of interest for planetary regoliths in the visible-near-IR wavelength region can be represented to a reasonable approximation by two-parameter, double Henyey-Greenstein functions. When the two parameters of this function are plotted against one another they are found to be inversely correlated and lie within a restricted zone shaped like a hockey stick within the parameter space. The centroid of the zone is a curve that can be represented by a simple empirical equation. The wide variety of types of particles used to construct the plot implies that this equation may represent most of the particles found in regoliths. This means that when modeling the bidirectional reflectance of a regolith it may be possible to reduce the number of parameters necessary to specify the reflectance, and also to characterize the entire single particle phase function from observations at phase angles less than 90°. Even if the hockey stick relation has a finite width, rather than being a line, it restricts the parameter space that must be searched when fitting data. The curve should also be useful for forward modeling particle phase functions.

  17. The planarity of the stickface motion in the field hockey hit.

    The field hockey hit is an important but poorly understood stroke. In this study, we investigated the planarity of the stickface motion during the downswing to better characterize the kinematics and to assess the suitability of planar pendulum models for simulating the hit. Thirteen experienced female field hockey players were filmed executing hits with a single approach step, and the kinematics of the centre of the stickface were measured. A method was developed for identifying how far back from impact the stickface motion was planar. Orthogonal regression was used to fit least-squares planes to the stickface path during sections of the downswing of varying length, with each section ending at impact. A section was considered planar if the root mean square residual between the stickface path and the fitted plane was less than 0.25% of the distance travelled by the stickface during that period. On average, the stickface motion was planar for the last 83 ± 12% of its downswing path, with the length of the planar section ranging from 1.85 m to 2.70 m. The suitability of a planar model for the stickface motion was supported, but further investigation of the stick and arm kinematics is warranted. PMID:22221186

    In spite of the well-known benefits that have been shown, few studies have looked at the practical applications of high-intensity interval training (HIIT) on athletic performance. This study investigated the effects of a HIIT program compared to traditional continuous endurance exercise training. 24 hockey players were randomly assigned to either a continuous or high-intensity interval group during a 4-week training program. The interval group (IG) was involved in a periodized HIIT program. The continuous group (CG) performed moderate intensity cycling for 45-60 min at an intensity that was 65% of their calculated heart rate reserve. Body composition, muscle thickness, anaerobic power, and on-ice measures were assessed pre- and post-training. Muscle thickness was significantly greater in IG (p=0.01) when compared to CG. The IG had greater values for both ∆ peak power (p<0.003) and ∆ mean power (p<0.02). Additionally, IG demonstrated a faster ∆ sprint (p<0.02) and a trend (p=0.08) for faster ∆ endurance test time to completion for IG. These results indicate that hockey players may utilize short-term HIIT to elicit positive effects in muscle thickness, power and on-ice performance.

    The aim of this study was to investigate the relations among situational motivational climate, dispositional approach and avoidance achievement goals, perceived sport ability, and enjoyment in Finnish male junior ice hockey players. The sample comprised 265 junior B-level male players with a mean age of 17.03 years (SD = 0.63). Players filled questionnaires tapping their perceptions of coach motivational climate, achievement goals, perceived sport ability, and enjoyment. For the statistical analysis, players were divided into high and low perceived sport ability groups. Multigroup structural equation modeling (SEM) revealed an indirect path from task-involving motivational climate via task-approach goal to enjoyment. Additionally, SEM demonstrated four other direct associations, which existed in both perceived ability groups: from ego-involving motivational climate to ego-approach and ego-avoidance goals; from ego-approach goal to ego-avoidance goal; and from task-avoidance goal to ego-avoidance goal. Additionally, in the high perceived sport ability group, there was an association from task-involving motivational climate to enjoyment. The results of this study reveal that motivational climate emphasizing effort, personal development and improvement, and achievement goal mastering tasks are significant elements of enjoyment in junior ice hockey.

    Research in "stop-and-go" sports has demonstrated that carbohydrate ingestion improves performance and fatigue, and that dehydration of ∼1.5%-2% body mass (BM) loss results in decreased performance, increased fatigue, and increased core temperature. The purpose of this investigation was to assess the physiological, performance, and fatigue-related effects of maintaining hydration with a carbohydrate-electrolyte solution (CES) versus dehydrating by ∼2% BM (no fluid; NF) during a 70-min ice hockey scrimmage. Skilled male hockey players (n = 14; age, 21.3 ± 0.2 years; BM, 80.1 ± 2.5 kg; height, 182.0 ± 1.2 cm) volunteered for the study. Subjects lost 1.94% ± 0.1% BM in NF, and 0.12% ± 0.1% BM in CES. Core temperature (Tc) throughout the scrimmage (10-50 min) and peak Tc (CES: 38.69 ± 0.10 vs. NF: 38.92 ± 0.11 °C; p performance was improved in CES versus NF and fatigue was lower following the CES trial. The results indicated that ingesting a CES to maintain BM throughout a 70-min hockey scrimmage resulted in improved hockey performance and thermoregulation, and decreased fatigue as compared with drinking no fluid and dehydrating by ∼2%.

    Full Text Available Nitrogen dioxide (NO2 is a toxic gas, a product of combustion in malfunctioning ice-resurfacing machines. NO2 poisoning is rare but potentially lethal. The authors report a case of mass NO2 poisoning involving 15 amateur ice hockey players in the Czech Republic. All players were treated in the Department of Respiratory Diseases at Brno University Hospital in November 2010 – three as inpatients because they developed pneumonitis. All patients were followed-up until November 2011. Complete recovery in all but one patient was achieved by December 2010. None of the 15 patients developed asthma-like disease or chronic cough. Corticosteroids appeared to be useful in treatment. Electric-powered ice-resurfacing machines are preferable in indoor ice skating arenas.

  8. Heat transfer in ice hockey halls: measurements, energy analysis and analytical ice pad temperature profile

    Ferrantelli, Andrea

    2015-01-01

    We consider heat transfer processes in an ice hockey hall, during operating conditions, with a bottom-up approach based upon on-site measurements. Detailed temperature data of both the ice pad and the air above the ice rink are used for a heat balance calculation in the steady-state regime, which quantifies the impact of each single heat source. We solve the heat equation in the ice slab in transient regime, and obtain a general analytical formula for the temperature profile. This solution is then applied to the resurfacing process by using our measurements as (time-dependent) boundary conditions (b.c.), and compared to an analogous numerical computation with good agreement. Our analytical formula is given with implicit initial condition and b.c., therefore it can be used not only in ice halls, but in a large variety of engineering applications.

The goal of the current study was to determine the overall use of visors among non-rookie NHL players in the 2013–2014 season and assess factors influencing their uptake. This was an observational, cross-sectional study using active NHL rosters and demographic information obtained from the official NHL website. Visor use was determined based on in-game video or images at two different time points in the 2013–2014 season. The use of visors during the 2013–2014 season was 75.2% among non-rookie players. When rookies were included, the overall use of visors was 77.8%. Compared to Canadian-born players, European players were significantly more likely to choose to wear a visor (odds ratio [OR] 3.48, 95% confidence interval [CI] 1.96–6.17. Players in the younger age-groups, particularly those younger than 24 years (OR 5.67, 95% CI 2.52–5.76 and those between 24 and 28 years (OR 2.18, 95% CI 1.23–3.87, were more likely to wear a visor compared to older players. Overall, visor use continues to grow in the NHL independently of new legislation, and is more likely in younger players and those of European origin.Keywords: ice hockey, facial protection, professional sports, eye injuries, safety

  13. Tsunami Hockey

    2013-12-01

    An important issue that vexes tsunami warning centers (TWCs) is when to cancel a tsunami warning once it is in effect. Emergency managers often face a variety of pressures to allow the public to resume their normal activities, but allowing coastal populations to return too quickly can put them at risk. A TWC must, therefore, exercise caution when cancelling a warning. Kim and Whitmore (2013) show that in many cases a TWC can use the decay of tsunami oscillations in a harbor to forecast when its amplitudes will fall to safe levels. This technique should prove reasonably robust for local tsunamis (those that are potentially dangerous within only 100 km of their source region) and for regional tsunamis (whose danger is limited to within 1000km of the source region) as well. For ocean-crossing destructive tsunamis such as the 11 March 2011 Tohoku tsunami, however, this technique may be inadequate. When a tsunami propagates across the ocean basin, it will encounter topographic obstacles such as seamount chains or coastlines, resulting in coherent reflections that can propagate great distances. When these reflections reach previously-impacted coastlines, they can recharge decaying tsunami oscillations and make them hazardous again. Warning center scientists should forecast sea-level records for 24 hours beyond the initial tsunami arrival in order to observe any potential reflections that may pose a hazard. Animations are a convenient way to visualize reflections and gain a broad geographic overview of their impacts. The Pacific Tsunami Warning Center has developed tools based on tsunami simulations using the RIFT tsunami forecast model. RIFT is a linear, parallelized numerical tsunami propagation model that runs very efficiently on a multi-CPU system (Wang et al, 2012). It can simulate 30-hours of tsunami wave propagation in the Pacific Ocean at 4 arc minute resolution in approximately 6 minutes of real time on a 12-CPU system. Constructing a 30-hour animation using 1 minute simulated time steps takes approximately 50 minutes on the same system. These animations are generated quickly enough to provide decision support for emergency managers whose coastlines may be impacted by the tsunami several hours later. Tsunami reflections can also aid in determining the source region for those tsunamis generated by non-seismic mechanisms without a clear source such as meteotsunamis, tsunamis generated by meteorological phenomena. A derecho that crossed the New Jersey coast and entered the Atlantic Ocean at approximately 1500 UTC June 13, 2013 generated a meteotsunami that struck the northeast coast of the US causing several injuries. A DART sensor off Montauk, NY, recorded tsunami waves approximately 200 minutes apart. We show how the arrival times of the tsunamis recorded by this DART can help to constrain the source region of the meteotsunami. We also examine other reflections produced by the Haida Gwaii 2012, Tohoku 2011, and other tsunamis.

    The drag flick is the preferred method of scoring during a penalty corner in field hockey. Performing the drag flick requires a combination of strength, coordination and timing, which may increase susceptibility to injuries. However, injury prevalence in drag flickers has not previously been investigated. Therefore, this study compared the injury prevalence and severity of lower limb and lower back injuries between drag flickers and non-drag flickers in field hockey. A total of 432 local, national and international adult field hockey players (242 males, 188 females) completed an online questionnaire to retrospectively determine the 3-month prevalence and severity of ankle, knee, hip and lower back injuries. Of this group, 140 self-identified as drag flickers and 292 as non-drag flickers. The results showed that drag flickers had significantly higher prevalence of hip (OR: 1.541; 95% CI: 1.014, 2.343) and lower back injury (OR: 1.564; 95% CI: 1.034, 2.365) compared to non-drag flickers. No significant differences were observed between drag flickers and non-drag flickers in injury prevalence at the ankle and knee. There were no significant between-group differences in injury severity scores. Overall, the prevalence of hip and lower back injuries was significantly higher in drag flickers compared to non-drag flickers. PMID:26760078

    The optimal method to develop expertise in ultrasound-guided regional anaesthesia is unknown. Studies of laryngoscopic expertise in novices demonstrate that the choice of laryngoscope affects performance. In this study, we aimed to compare the effect of two different linear array transducers (38-mm standard vs 25-mm hockey stick) on novice performance of ultrasound-guided needle advancement. Following randomisation, participants watched a video model of expert performance of ultrasound-guided needle advancement. Recruits performed the modelled task on a turkey breast model. The median (IQR [range]) composite error score was statistically significantly larger for participants in the hockey stick transducer group compared with the standard transducer group; 10.0 (7.3-14.3 [2.5-29.0]) vs 7.5 (4.5-10.0 [2.0-28.0]) respectively, (p = 0.01). This study has demonstrated that performance of ultrasound-guided needle advancement by novice operators after simple video instruction is better (as assessed using a composite error score) with a standard 38-mm transducer than with a 25-mm hockey stick transducer.

In the 2013/2014 season, 14 of them still played in the top league (the control group, while 10 played in the first league (the experimental group. The study was conducted one week after the end of the playoffs in the seasons under consideration. The results revealed that only in the experimental group the analysed variables changed significantly between the seasons. In the Wingate test, significant changes were only noted in mean relative power (a decrease from 9.91 to 9.14 W/kg; p=0.045 and relative total work (a decrease from 299.17 to 277.22 J/kg; p=0.048. The ramp test indicated significantly lower power output in its final stages (364 compared with 384 W; p=0.034, as well as a significant decrease in relative VO2max (from 52.70 to 48.30 ml/min/kg. Blood lactate concentrations were recorded at the 3rd, 6th, 9th and 12th min of recovery after the ramp test. The rate of post-exercise recovery, ∆LA, recorded after the ramp test turned out to be significantly lower. The times recorded in the on-ice “6x30 m stop” test increased from 32.18 to 33.10 s (p=0.047. The study showed that playing in a lower league where games were less intensive, training sessions shorter and less frequent, had an adverse effect on the performance level of the investigated players. Lower VO2max recorded in the study participants slowed down their rates of post-exercise recovery and led to a significantly worse performance in the 6x30 m stop test, as well as lower relative power and relative total work in the Wingate test.

  6. Why do sleeping nematodes adopt a hockey-stick-like posture?

    Directory of Open Access Journals (Sweden)

    Nora Tramm

    Full Text Available A characteristic posture is considered one of the behavioral hallmarks of sleep, and typically includes functional features such as support for the limbs and shielding of sensory organs. The nematode C. elegans exhibits a sleep-like state during a stage termed lethargus, which precedes ecdysis at the transition between larval stages. A hockey-stick-like posture is commonly observed during lethargus. What might its function be? It was previously noted that during lethargus, C. elegans nematodes abruptly rotate about their longitudinal axis. Plausibly, these "flips" facilitate ecdysis by assisting the disassociation of the old cuticle from the new one. We found that body-posture during lethargus was established using a stereotypical motor program and that body bends during lethargus quiescence were actively maintained. Moreover, flips occurred almost exclusively when the animals exhibited a single body bend, preferentially in the anterior or mid section of the body. We describe a simple biomechanical model that imposes the observed lengths of the longitudinally directed body-wall muscles on an otherwise passive elastic rod. We show that this minimal model is sufficient for generating a rotation about the anterior-posterior body axis. Our analysis suggests that posture during lethargus quiescence may serve a developmental role in facilitating flips and that the control of body wall muscles in anterior and posterior body regions are distinct.

The nematode C. elegans exhibits a sleep-like state during a stage termed lethargus, which precedes ecdysis at the transition between larval stages. A hockey-stick-like posture is commonly observed during lethargus. What might its function be? It was previously noted that during lethargus, C. elegans nematodes abruptly rotate about their longitudinal axis. Plausibly, these "flips" facilitate ecdysis by assisting the disassociation of the old cuticle from the new one. We found that body-posture during lethargus was established using a stereotypical motor program and that body bends during lethargus quiescence were actively maintained. Moreover, flips occurred almost exclusively when the animals exhibited a single body bend, preferentially in the anterior or mid section of the body. We describe a simple biomechanical model that imposes the observed lengths of the longitudinally directed body-wall muscles on an otherwise passive elastic rod. We show that this minimal model is sufficient for generating a rotation about the anterior-posterior body axis. Our analysis suggests that posture during lethargus quiescence may serve a developmental role in facilitating flips and that the control of body wall muscles in anterior and posterior body regions are distinct.

    Computerized neurocognitive tests are frequently used to assess pediatric sport-related concussions; however, only 1 study has focused on the test-retest reliability of the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) in high school athletes and age influences have largely been ignored. Therefore, the purpose was to investigate the test-retest reliability of ImPACT and underlying age influences in a pediatric population. Two hundred (169 men and 31 women) youth ice hockey players completed ImPACT before/after a 6-month season. Reliability was assessed using Pearson correlation coefficients, intraclass correlation coefficients (ICCs), and regression-based methods (RBz). ICCs for the sample ranged from .48 to .75 (single)/.65 to .86 (average). In general, the older athletes (15-18: Single/Average ICCs = .35-.75/.52-.86) demonstrated greater reliability across composites than the younger athletes (11-14: Single/Average ICCs = .54-.63/.70-.77). Although there was variation in athletes' performance across two test administrations, RBz revealed that only a small percentage of athletes performed beyond 80%, 90%, and 95% confidence intervals. Statistical metrics demonstrated reliability coefficients for ImPACT composites in a pediatric sample similar to previous studies, and also revealed important age-related influences. PMID:27084734

    SUMMARY Understanding the mental health needs of lesbian and bisexual (sexual minority) women is an integral part of designing and providing appropriate mental health services and treatment for them. In an effort to understand the mental health needs of sexual minority women who seek community treatment, a chart review was conducted of the 223 lesbian and bisexual women who presented for services between July 1, 1997 and December 31, 2000 at Fenway Community Health in Boston, MA. Data are based on clients' self-reports and clinician assessments of clients' presenting problem, relevant developmental history, prior mental health and substance abuse treatment, current reports of emotional/psychological symptoms, and areas of impaired functioning. Although substance abuse and suicidal ideation were commonly reported problems, other concerns were more frequently reported. High percentages of lesbians and bisexual women reported relationship concerns and lack of adequate social networks; rates of depression and anxiety based on clinicians' assessments were also high. Overall, lesbians and bisexual women did not differ in the issues they brought to treatment or level or types of impairment. Compared with previous community survey samples, however, study participants appeared to be healthier than general, non-clinical samples of self-identified lesbians, possibly reflecting the special characteristics of sexual minority women who seek treatment in specialized community sites such as the Fenway. Although patients who come to these sites may not represent the more general population of sexual minority women, community health centers known to serve lesbian, gay, bisexual and transgender (LGBT) individuals may be fruitful access points for studying the mental health status and treatment needs of sexual minority women.

    Previous ice hockey research has focused on physiological profiles and determinants of skating speed, but few studies have examined the association of preseason player evaluations with a measure of season-long performance. Understanding which tests are most predictive of player performance could help coaches organize practice and training more effectively. The purpose of this study was to describe physical characteristics and skill levels of 24 members of an NCAA Division I men's ice hockey team and relate them to game performance over the course of a season as measured by plus/minus (+/-) score. Subjects performed a battery of preseason tests including treadmill maximal aerobic capacity, body fat, leg press, push-ups, bench press, chin-ups, and sprinting ability both on and off ice. Pearson and Spearman correlations were used to examine correlations between preseason measures and +/- score. One coach also subjectively grouped the top and bottom 6 players, and analysis of variance was used to examine any differences in preseason measures and +/- score between these 2 groups. Leg press, chin-ups, bench press, and repeat sprint performance were significantly correlated with +/- score (r = 0.554, 0.462, 0.499, and -0.568, respectively). Teams with limited time and resources may choose to perform these tests to evaluate player potential efficiently. Only +/- score differed between top and bottom players suggesting that +/- accurately reflected the coach's perception of player success in this sample. PMID:21478763

    The aim of this study was to investigate the technique adaptations made when performing sprint-based tasks without (free condition) and with (constrained condition) the constraints of carrying a field hockey stick. Three free and three constrained maximal sprint accelerations were performed by 18 experienced university male field hockey players (age = 20 +/- 1 years, body mass = 73.3 +/- 7.1 kg, and stature = 1.78 +/- 0.05 m). An automatic motion analysis system tracked sagittal plane active marker locations (200 Hz). M sprint velocity during the 18-22 m (free: 8.03 +/- 0.43 m/s; constrained: 7.93 +/- 0.36 m/s) interval was significantly (p = 0.03) different between free and constrained conditions. While the M stride length and stride frequency was similar between free and constrained conditions in the 2-13 m capture volume, the free condition elicited a 0.10 m/s faster (p = 0.03) stride velocity. Further significant differences were found between free and constrained kinematic profiles (p < or = 0.05) for the hip angular velocity at touchdown during the 2-12 m interval of the sprints and in the overall sprint technique coordination between free and constrained conditions. Performance and technique adaptations indicated that sprint-training protocols for field sports should integrate specific equipment constraints to ensure explicit replication of the mechanical demands of the skills underpinning superior performance.

    This work is the first of a series of articles addressing the energy optimization in ice hockey halls. Here we outline an analytic method to predict in which design and operating conditions the COP of the entire cooling system (refrigerator and cooling tower) ${\\rm COP}_{sys}$ is maximum. ${\\rm COP}_{sys}$ is investigated as a function of several variables, like electric consumption and brine physical properties. With this method, the best configuration and brine choices for the system can therefore be determined in advance. We estimate the optimal design of an average-sized ice rink, including pipe diameter, depth and brine type (ethylene glycol and ammonia). We also single out an optimal brine density and show the impact of the electric consumption of the pump on ${\\rm COP}_{sys}$. Our theoretical predictions are validated with heat flow measurement data obtained at an ice hockey hall in Finland. They are also confronted with technical and cost-related constraints, and implemented by simulations with the pr...

    2015-09-01

    Full Text Available Post-physical training changes in iron metabolism in the human body often occur. To fully describe these processes, fifteen male Polish National Team field hockey players (age 27.7 ± 5.2 years, body mass 72.8 ± 7.6 kg and body height 177.1 ± 5.7 cm were examined in three phases of an annual training cycle: preparatory (T1, competitive (T2 and transition (T3. To assess aerobic fitness, maximal oxygen uptake (VO2max was evaluated. Based on the iron concentration, the changes in total iron binding capacity (TIBC, unsaturated iron binding capacity (UIBC and other selected haematological indicators (haemoglobin, erythrocytes, mean corpuscular haemoglobin - MCH in iron metabolism were estimated. The average values of maximum oxygen uptake increased from 54.97 ± 3.62 ml·kg−1·min−1 in T1 to 59.93 ± 3.55 ml·kg−1·min−1 in T2 (p<0.05 and then decreased to 56.21 ± 4.56 ml·kg−1·min−1 in T3 (p<0.05. No statistically significant changes in the erythrocyte count were noted. The MCH and haemoglobin concentration decreased between T1 and T2. The maximal exercise test caused a significant (p<0.05 increase in the plasma iron concentration during the competition and transition phases. Progressive but non-significant increases in resting iron concentration, TIBC and UIBC in the analysed annual training cycle were noted. To show global changes in iron metabolism in the human body, it is necessary to determine additional variables, i.e. UIBC, TIBC, haemoglobin, MCH or the erythrocyte count. The direction of changes in iron metabolism depends on both the duration and intensity of the physical activity and the fitness level of the subjects.

  2. BOOK REVIEW: Minority Games

    Science.gov (United States)

    Metzler, R.

    2005-02-01

    New branches of scientific disciplines often have a few paradigmatic models that serve as a testing ground for theories and a starting point for new inquiries. In the late 1990s, one of these models found fertile ground in the growing field of econophysics: the Minority Game (MG), a model for speculative markets that combined conceptual simplicity with interesting emergent behaviour and challenging mathematics. The two basic ingredients were the minority mechanism (a large number of players have to choose one of two alternatives in each round, and the minority wins) and limited rationality (each player has a small set of decision rules, and chooses the more successful ones). Combining these, one observes a phase transition between a crowded and an inefficient market phase, fat-tailed price distributions at the transition, and many other nontrivial effects. Now, seven years after the first paper, three of the key players—Damien Challet, Matteo Marsili and Yi-Cheng Zhang—have published a monograph that summarizes the current state of the science. The book consists of two parts: a 100-page overview of the various aspects of the MG, and reprints of many essential papers. The first chapters of Part I give a well-written description of the motivation and the history behind the MG, and then go into the phenomenology and the mathematical treatment of the model. The authors emphasize the `physics' underlying the behaviour and give coherent, intuitive explanations that are difficult to extract from the original papers. The mathematics is outlined, but calculations are not carried out in great detail (maybe they could have been included in an appendix). Chapter 4 then discusses how and why the MG is a model for speculative markets, how it can be modified to give a closer fit to observed market statistics (in particular, reproducing the `stylized facts' of fat-tailed distributions and volatility clustering), and what conclusions one can draw from the behaviour of the MG

    We investigated the temperature dependences of the dielectric anisotropy, birefringence, order parameter, splay elastic constant, and rotational viscosity of rodlike nematic liquid crystals (RLCs) doped with hockey-stick-shaped liquid crystals (HLCs). Although the order parameter of the HLC-RLC mixtures was similar to that of the pure RLC, the dielectric anisotropy and the birefringence of the mixtures were decreased or increased depending on the structure of the HLC molecule. In addition, the activation energies of the mixtures were different, which implies that the intramolecular structure of the HLC molecule had more influence on the electrooptical properties of the HLC-RLC binary mixtures than the inter-molecular interaction between the HLC and the RLC molecules.

    The phenomenon postactivation potentiation can possibly be used to acutely improve sprint performance. The purpose of this study was to investigate the effect of body-loaded half-squats with added whole body vibration (WBV) on subsequent 20 m on-ice sprint performance. Fifteen male ice-hockey players performed 4 test sessions on separate days and in a randomized order. Two of this test sessions were with WBV and 2 were with noWBV and the best sprint time was used to determine effectiveness. Each test session included preconditioning 30 seconds half-squat exercise, 2 of which were supplemented with 50 Hz WBV at a amplitude of 3 mm. One minute after the cessation of the preconditioning exercise, the 20 m sprint test was performed. Intermediate time was sampled after 10 m. Preconditioning exercise performed with 50 Hz WBV resulted in superior 10 m and 20 m sprint performance compared to preconditioning exercise performed without WBV (1.84 6 0.10 seconds vs. 1.89 6 0.10 seconds and 3.14 6 0.13 vs. 3.17 6 0.13 seconds, respectively, p # 0.01). There was no difference between the protocols in perceived well-being of the legs before the warm-up or after the warm up (p = 0.3). However, there was an improved well-being in the legs immediately after the preconditioning exercise with WBV (p , 0.05). In conclusion, preconditioning exercise performed with WBV at 50 Hz seems to enhance on-ice sprint performance in ice-hockey players. This suggests that coaches can incorporate such exercise into the preparation to specific sprint training to improve the quality of the training.

    2014-07-01

    The aim of this study was to examine the impact of maximum sprint speed on peak and mean sprint speed during youth female field hockey matches. Two high-level female field hockey teams (U-17, n = 24, and U-21, n = 20) were monitored during a 4-game international test series using global position system technology and tested for maximum sprint speed. Dependent variables were compared using a 3-factor ANOVA (age group, position, and speed classification); effect sizes (Cohen d) and confidence limits were also calculated. Maximum sprint speed was similar between age groups and positions, with faster players having greater speed than slower players (29.3 ± 0.4 vs 27.2 ± 1.1 km/h). Overall, peak match speed in youth female field hockey players reaches approximately 90% of maximum sprint speed. Absolute peak match speed and mean sprint speed during matches were similar among the age groups (except match 1) and positions (except match 2); however, peak match speed was greater for faster players in matches 3 and 4. No differences were observed in the relative proportion for mean sprint speeds for age groups or positions, but slower players consistently displayed similar relative mean sprint speeds by using a greater proportion of their maximum sprint speed.

    Objectives The purpose of this study was to examine whether field-based and/or laboratory-based assessments are valid tools for predicting key performance characteristics of skating in competitive-level female hockey players. Design Cross-sectional study. Methods Twenty-three female ice hockey players aged 15–25 years (body mass: 66.1±6.3 kg; height: 169.5±5.5 cm), with 10.6±3.2 years playing experience volunteered to participate in the study. The field-based assessments included 20 m sprint, squat jump, countermovement jump, 30-second repeated jump test, standing long jump, single-leg standing long jump, 20 m shuttle run test, isometric leg pull, one-repetition maximum bench press, and one-repetition maximum squats. The laboratory-based assessments included body composition (dual energy X-ray absorptiometry), maximal aerobic power, and isokinetic strength (Biodex). The on-ice tests included agility cornering s-turn, cone agility skate, transition agility skate, and modified repeat skate sprint. Data were analyzed using stepwise multivariate linear regression analysis. Linear regression analysis was used to establish the relationship between key performance characteristics of skating and the predictor variables. Results Regression models (adj R2) for the on-ice variables ranged from 0.244 to 0.663 for the field-based assessments and from 0.136 to 0.420 for the laboratory-based assessments. Single-leg tests were the strongest predictors for key performance characteristics of skating. Single leg standing long jump alone explained 57.1%, 38.1%, and 29.1% of the variance in skating time during transition agility skate, agility cornering s-turn, and modified repeat skate sprint, respectively. Isokinetic peak torque in the quadriceps at 90° explained 42.0% and 32.2% of the variance in skating time during agility cornering s-turn and modified repeat skate sprint, respectively. Conclusion Field-based assessments, particularly single-leg tests, are an adequate

    This paper reviews the principles of calorimetric assay and evaluates its potential application to the minor actinides (U-232-4, Am-241, Am- 243, Cm-245, Np-237). We conclude that calorimetry and high- resolution gamma-ray isotopic analysis can be used for the assay of minor actinides by adapting existing methodologies for Pu/Am-241 mixtures. In some cases, mixtures of special nuclear materials and minor actinides may require the development of new methodologies that involve a combination of destructive and nondestructive assay techniques.

  2. Generic Hockey-Stick Model for Estimating Benchmark Dose and Potency: Performance Relative to BMDS and Application to Anthraquinone.

    Science.gov (United States)

    Bogen, Kenneth T

    2011-01-01

    Benchmark Dose Model software (BMDS), developed by the U.S. Environmental Protection Agency, involves a growing suite of models and decision rules now widely applied to assess noncancer and cancer risk, yet its statistical performance has never been examined systematically. As typically applied, BMDS also ignores the possibility of reduced risk at low doses ("hormesis"). A simpler, proposed Generic Hockey-Stick (GHS) model also estimates benchmark dose and potency, and additionally characterizes and tests objectively for hormetic trend. Using 100 simulated dichotomous-data sets (5 dose groups, 50 animals/group), sampled from each of seven risk functions, GHS estimators performed about as well or better than BMDS estimators, and a surprising observation was that BMDS mis-specified all of six non-hormetic sampled risk functions most or all of the time. When applied to data on rodent tumors induced by the genotoxic chemical carcinogen anthraquinone (AQ), the GHS model yielded significantly negative estimates of net potency exhibited by the combined rodent data, suggesting that-consistent with the anti-leukemogenic properties of AQ and structurally similar quinones-environmental AQ exposures do not likely increase net cancer risk. In addition to its simplicity and flexibility, the GHS approach offers a unified, consistent approach to quantifying environmental chemical risk. PMID:21731536

An optoelectronic motion analysis system was used to capture the drag-flicks with six cameras, sampling at 250 Hz. Select ground reaction force parameters were obtained from a force platform which registered the last support of the front foot. Twenty trials were captured from each subject. Both player groups showed significantly (p stick than the skilled subject. Normalised ground reaction forces of the gender groups were also smaller than that of the skilled drag-flicker. By comparing these players we established that the cues of the skill level are a wide stance, a whipping action (rapid back lift) of the stick followed by an explosive sequential movement of the pelvis, upper trunk and stick.

  6. Minority workers or minority human beings? A European dilemma

    Skutnabb-Kangas, Tove; Phillipson, Robert

    1996-07-01

    "European" identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as "European", and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

    The quantity of numbered minor planets has now well exceeded a quarter million. The new sixth edition of the Dictionary of Minor Planet Names, which is the IAU’s official reference work for the field, now covers more than 17,000 named minor planets. In addition to being of practical value for identification purposes, the Dictionary of Minor Planet Names provides authoritative information on the basis of the rich and colorful variety of ingenious names, from heavenly goddesses to artists, from scientists to Nobel laureates, from historical or political figures to ordinary women and men, from mountains to buildings, as well as a variety of compound terms and curiosities. This sixth edition of the Dictionary of Minor Planet Names has grown by more than 7,000 entries compared to the fifth edition and by more than 2,000 compared to the fifth edition, including its two addenda published in 2006 and 2009.

    Sexting is the sending or forwarding of sexually explicit photographs or videos of the sender or someone known to the sender via cell phone. It has become common practice among young people, as cell phones are being given to adolescents at ever younger ages. Youths often send messages without giving appropriate thought to the content of the images. In studies on the subject, rates of minors who have sent sexual images range from 4 to 25 percent, depending on the age of the youths surveyed, the content of the messages and other factors. Because transferring and viewing sexually explicit material when the subject is a minor can be considered child pornography, there can be serious legal consequences. Several states have enacted legislation to help differentiate between child pornography and sexting by minors. The trend reflected in statutes has been that minors involved in sexting without other exacerbating circumstances should be charged with a less serious offense. There is no clear national consensus on how sexting by minors is adjudicated, and therefore we compared several statutes. Case examples are used to illustrate the range of legal outcomes, from felony charges to no charges. Two sexting episodes that were followed by suicide are described. We also address the role of the forensic mental health professional.

    We used logistic regression on nationally representative data (General Social Survey, N = 10,668 and N = 6680) to examine how sexual minority status related to happiness. We considered two central dimensions of sexual minority status-sexual behavior and sexual identity. We distinguished between same-sex, both-sex, and different-sex-oriented participants. Because individuals transition between sexual behavior categories over the life course (e.g., from both-sex partners to only same-sex partners) and changes in sexual minority status have theoretical associations with well-being, we also tested the associations of transitions with happiness. Results showed that identifying as bisexual, gay, or lesbian, having both male and female partners since age 18, or transitioning to only different-sex partners was negatively related to happiness. Those with only same-sex partners since age 18 or in the past 5 years had similar levels of happiness as those with only different-sex partners since age 18. Additional tests showed that the majority of these happiness differences became non-significant when economic and social resources were included, indicating that the lower happiness was a product of structural and societal forces. Our findings clearly and robustly underscored the importance of taking a multi-faceted approach to understanding sexuality and well-being, demonstrating that not all sexual minority groups experience disadvantaged happiness. Our study calls for more attention to positive aspects of well-being such as happiness in examinations of sexual minorities and suggests that positive psychology and other happiness subfields should consider the role of sexual minority status in shaping happiness.

    The aim of this investigation was to establish median performance profiles for the six playing positions in elite women's indoor hockey and then identify whether these position-specific profiles could discriminate between qualifying (top four), mid-table and relegated teams in the 2011-2012 England Hockey premier league. Successful passing in relegated teams was significantly lower (P teams in four of the five outfield positions. Furthermore, the right backs of qualifying teams demonstrated significantly fewer (P teams (x̃ = 19.5 ± CLs 21.0 and 17.0; x̃ = 7.5 ± CLs 8.0 and 6.0, respectively). Finally, the right forwards of relegated teams demonstrated significantly fewer (P teams (x̃ = 5.0 ± CLs 6.0 and 3.0, respectively) and significantly more (P teams (x̃ = 3.0 ± CLs 3.0 and 2.0, respectively). Based on these findings, coaches should adapt tactical strategies and personnel deployment accordingly to enhance the likelihood of preparing a qualifying team. Research should build from these data to examine dribbling, pressing and patterns of play when outletting.

  1. Effect of hockey-stick-shaped molecules on the critical behavior at the nematic to isotropic and smectic-A to nematic phase transitions in octylcyanobiphenyl

    2015-03-01

    In the field of soft matter research, the characteristic behavior of both nematic-isotropic (N -I ) and smectic-A nematic (Sm -A N ) phase transitions has gained considerable attention due to their several attractive features. In this work, a high-resolution measurement of optical birefringence (Δ n ) has been performed to probe the critical behavior at the N -I and Sm -A N phase transitions in a binary system comprising the rodlike octylcyanobiphenyl and a laterally methyl substituted hockey-stick-shaped mesogen, 4-(3-n -decyloxy-2-methyl-phenyliminomethyl)phenyl 4-n -dodecyloxycinnamate. For the investigated mixtures, the critical exponent β related to the limiting behavior of the nematic order parameter close to the N -I phase transition has come out to be in good conformity with the tricritical hypothesis. Moreover, the yielded effective critical exponents (α', β', γ') characterizing the critical fluctuation near the Sm -A N phase transition have appeared to be nonuniversal in nature. With increasing hockey-stick-shaped dopant concentration, the Sm -A N phase transition demonstrates a strong tendency to be driven towards a first-order nature. Such a behavior has been accounted for by considering a modification of the effective intermolecular interactions and hence the related coupling between the nematic and smectic order parameters, caused by the introduction of the angular mesogenic molecules.

  3. Breast screening and ethnic minorities.

    Science.gov (United States)

    Hoare, T

    1996-09-01

    The concern for minority ethnic women is whether they are disadvantaged either in terms of the incidence of breast cancer or because of a lower uptake of screening. There are considerable worldwide variations in the incidence of breast cancer. The lowest rates are found in Chinese, Japanese and Arabic populations and women from the Indian subcontinent, and are 2-3 times lower than that of the UK. This may change in future generations. Although minority ethnic women are not a high risk group for the breast screening programme, in absolute terms breast cancer is a major health problem. Very few studies have measured ethnic differences in the uptake of screening, and they may be confounded by such factors as socio-economic group. When this is accounted for, uptake by Asian women may not necessarily be lower than by other women in the same area and can be higher for black than white women. One of the most important reasons for non-attendance is inaccurate screening registers, compounded for Asian women by their return, or extended visits, to the Indian subcontinent. A further organisational issue concerns poor awareness of minority ethnic naming systems, causing confusion over the receipt of invitations. Comprehension of the concept of screening may be difficult for minority ethnic women yet there has been little evaluation of strategies to promote understanding. However a randomised controlled trial of a linkworker intervention, designed to be feasible for implementation on a population basis, showed no increase in the uptake of breast screening by Asian women. This does not undermine linkworkers' role but suggests that their efforts should be used in other ways. It is essential to assess the relative importance of reasons for low uptake and evaluate measures to meet any unmet need, so that resources can be directed in the most effective way. PMID:8782797

Off-ice variables assessed were years of playing experience, height, weight and percent body fat and off-ice performance variables included vertical jump (VJ), 40-yd dash (36.58m), 1-RM squat, pro-agility, Wingate peak power and peak power percentage drop (% drop), and 1.5 mile (2.4km) run. Results indicated that 40-yd dash (36.58m), VJ, 1.5 mile (2.4km) run, and % drop were significant predictors of skating performance for repeat skate (slowest, fastest, and average time) and 44.80 m speed time, respectively. Four predictive equations were derived from multiple regression analyses: 1) slowest repeat skate time = 2.362 + (1.68 x 40-yd dash time) + (0.005 x 1.5 mile run), 2) fastest repeat skate time = 9.762 - (0.089 x VJ) - (0.998 x 40-yd dash time), 3) average repeat skate time = 7.770 + (1.041 x 40-yd dash time) - (0.63 x VJ) + (0.003 x 1.5 mile time), and 4) 47.85 m speed test = 7.707 - (0.050 x VJ) - (0.01 x % drop). It was concluded that selected off-ice tests could be used to predict on-ice performance regarding speed and recovery ability in Division III male and female hockey players. Key pointsThe 40-yd dash (36.58m) and vertical jump tests are significant predictors of on-ice skating performance specific to speed.In addition to 40-yd dash and vertical jump, the 1.5 mile (2.4km) run for time and percent power drop from the Wingate anaerobic power test were also significant predictors of skating performance that incorporates the aspect of recovery from skating activity.Due to the specificity of selected off-ice variables as predictors of on-ice performance, coaches can

  20. Myelin Water Fraction Is Transiently Reduced after a Single Mild Traumatic Brain Injury--A Prospective Cohort Study in Collegiate Hockey Players.

    Directory of Open Access Journals (Sweden)

    Alexander D Wright

    Full Text Available Impact-related mild traumatic brain injuries (mTBI are a major public health concern, and remain as one of the most poorly understood injuries in the field of neuroscience. Currently, the diagnosis and management of such injuries are based largely on patient-reported symptoms. An improved understanding of the underlying pathophysiology of mTBI is urgently needed in order to develop better diagnostic and management protocols. Specifically, dynamic post-injury changes to the myelin sheath in the human brain have not been examined, despite 'compromised white matter integrity' often being described as a consequence of mTBI. In this preliminary cohort study, myelin water imaging was used to prospectively evaluate changes in myelin water fraction, derived from the T2 decay signal, in two varsity hockey teams (45 players over one season of athletic competition. 11 players sustained a concussion during competition, and were scanned at 72 hours, 2 weeks, and 2 months post-injury. Results demonstrated a reduction in myelin water fraction at 2 weeks post-injury in several brain areas relative to preseason scans, including the splenium of the corpus callosum, right posterior thalamic radiation, left superior corona radiata, left superior longitudinal fasciculus, and left posterior limb of the internal capsule. Myelin water fraction recovered to pre-season values by 2 months post-injury. These results may indicate transient myelin disruption following a single mTBI, with subsequent remyelination of affected neurons. Myelin disruption was not apparent in the athletes who did not experience a concussion, despite exposure to repetitive subconcussive trauma over a season of collegiate hockey. These findings may help to explain many of the metabolic and neurological deficits observed clinically following mTBI.

  1. Assessing mental disability in minors.

    Science.gov (United States)

    Mozes, T; Tyano, S

    2006-06-01

    Forensic psychiatry devotes a great deal of attention to the "imprecise" and "insufficiently scientific" nature of psychiatric disability assessment, and, for this reason, it is vitally important to establish a reliable method of assessing different levels of disability. The assessment of mental disability in minors is unique in that it involves developmental aspects, which affect the formation and outcome of the disability. The relationship between disability and development is reciprocal: disability can affect development, thereby intensifying the degree of disability, while development affects integration of the disability into the personality and self-image, thereby preventing or reducing the transformation of disability into handicap. Only an understanding of both the psychopathological structure and its interaction with developmental elements can lead to an accurate assessment of the degree of disability. Such an understanding is vital to the proper practice of forensic psychiatry. We hereby propose a new formula for disability quantification which provides an arithmetical means for the calculation of disability percentages in minors, and we recommend its use in the assessment of demands for National Insurance benefits and compensation claims. The relationship between this new formula and the existing Children's Global Assessment Scale (CGAS) functional scale, when tested retrospectively on 50 clinical reports composed by the writers of this article, showed a good correlation in the results obtained independently by each writer. Two case studies are presented here. A further evaluation by objective evaluators is necessary in order to construct a model for a final objective evaluation of disability in children and adolescents. PMID:16929808

    The ternary Goldbach conjecture states that every odd number $n\\geq 7$ is the sum of three primes. The estimation of sums of the form $\\sum_{p\\leq x} e(\\alpha p)$, $\\alpha = a/q + O(1/q^2)$, has been a central part of the main approach to the conjecture since (Vinogradov, 1937). Previous work required $q$ or $x$ to be too large to make a proof of the conjecture for all $n$ feasible. The present paper gives new bounds on minor arcs and the tails of major arcs. For $q\\geq 4\\cdot 10^6$, these bounds are of the strength needed to solve the ternary Goldbach conjecture. Only the range $q\\in \\lbrack 10^5, 4\\cdot 10^6\\rbrack$ remains to be checked, possibly by brute force, before the conjecture is proven for all $n$. The new bounds are due to several qualitative improvements. In particular, this paper presents a general method for reducing the cost of Vaughan's identity, as well as a way to exploit the tails of minor arcs in the context of the large sieve.

    2011-08-01

    Ethnic minority-majority unions-also referred to as mixed ethnic unions-are often seen as the ultimate evidence of the integration of ethnic minorities into their host societies. We investigated minority-majority unions in Estonia, where ethnic minorities account for one-third of the total population (Russians 26%, followed by Ukrainians, Byelorussians, Finns and other smaller groups). Using data from the 2000 Estonian census and regression models, we found that Slavic women are less likely to be in minority-majority unions than are members of other minority groups, with Russians being the least likely. Finns, who are culturally most similar to the Estonian majority population, are the most likely to form a union with an Estonian. For ethnic minority women, the likelihood of being in minority-majority unions is highest in rural areas and increases over generations, with third-generation immigrants being the most likely. Estonian women are most likely to have a minority partner when they or their parents were born abroad and when they live in urban areas. Our findings suggest that both the opportunity to meet potential partners and openness to other ethnic groups are important factors for understanding the dynamics of minority-majority unions.

    Introduction A growing body of evidence reveals higher rates of tobacco use among sexual minority populations relative to non-minority (“straight”) populations. This study seeks to more fully characterize this disparity by examining tobacco use by distinct sexual identities and gender to better understand patterns of: (1) cigarette smoking and smoking history; and (2) use of other tobacco products including cigars, pipes, hookah, e-cigarettes, and smokeless tobacco. Methods Data from the 2012–2013 National Adult Tobacco Survey, a random-digit dialed landline and cellular telephone survey of U.S. adults aged ≥18 years, were analyzed in 2014. A sexual minority category was created by combining gay, lesbian, and bisexual responses, along with those who selected an option for other non-heterosexual identities. Results Smoking prevalence was higher among sexual minority adults (27.4%) than straight adults (17.3%). Cigarette smoking was particularly high among bisexual women (36.0%). Sexual minority women started smoking and transitioned to daily smoking earlier than their straight peers. Use of other tobacco products was higher among sexual minority women: prevalence of e-cigarette (12.4%), hookah (10.3%), and cigar use (7.2%) was more than triple that of their straight female peers (3.4%, 2.5%, and 1.3%, respectively). Likewise, prevalence of sexual minority men’s e-cigarette (7.9%) and hookah (12.8%) use exceeded that of straight men (4.7% and 4.5%, respectively). Conclusions Tobacco use is significantly higher among sexual minority than straight adults, particularly among sexual minority women. These findings underscore the importance of tobacco control efforts designed to reach sexual minorities and highlight the heterogeneity of tobacco use within this population. PMID:26526162

    Compared to sexual minority men and heterosexual women, sexual minority women report elevated alcohol use in young adulthood. Heavy alcohol use and alcohol use disorders disproportionately affect sexual minority women across the lifespan, yet there is limited research investigating reasons for such associations. The present study investigates longitudinal associations between minority stress and both alcohol use as well as self-rated drinking consequences. Participants (N=1057) were self-identified lesbian (40.5%) and bisexual (59.5%) women between the ages of 18 to 25 recruited from across the U.S. using online advertisements. Participants completed four annual surveys. Hurdle mixed effects models were used to assess associations between minority stress and typical weekly drinking and drinking consequences one year later. Minority stress was not significantly associated with subsequent typical drinking. However, minority stress was significantly associated with having any alcohol consequences as well as the count of alcohol consequences one year later after controlling for covariates. Consistent with extant literature, this study provides evidence for a prospective association between minority stress experienced by sexual minority women and drinking consequences. This study also provides support for the potential impact of efforts to reduce minority stress faced by sexual minority women.

    Official language minorities (Francophones outside of Quebec and Anglophones in Quebec) make up about 6.4% of the Canadian population. Even though the Canadian constitution gives legal equality status to French and English, there is still room to ask if this equality is maintained in the health sector. In other words, do Francophone and Anglophone communities of Canada have the same health profiles regardless of their minority or majority status? Do they have access to the same health services and in the same conditions? The objective of this paper is to identify the health issues associated with belonging to a linguistic minority. Our research allows us to highlight the social and health disparities that can be attributed to belonging to a minority. In the Canadian context, which has two official languages, an equitable health policy will have to take into consideration language as a determinant of health. PMID:24289938

    US minority health issues involve racial/ethnic disparities that affect both women and men. However, women's health advocacy in the United States does not consistently address problems specific to minority women. The underlying evolution and political strength of the women's health and minority health movements differ profoundly. Women of color comprise only one quarter of women's health movement constituents and are, on average, socioeconomically disadvantaged. Potential alliances may be inhibited by vestiges of historical racial and social divisions that detract from feelings of commonality and mutual support. Nevertheless, insufficient attention to minority women's issues undermines the legitimacy of the women's health movement and may prevent important advances that can be achieved only when diversity is fully considered.

  9. Minority Serving College and University Cost Efficiencies

    Directory of Open Access Journals (Sweden)

    G. Thomas Sav

    2012-01-01

    Full Text Available Problem statement: Higher education minority enrollment growth has far outstripped white non-minority growth in the United States. Minority serving colleges and universities have disproportionately attended to that growth and will continue to play a critical role in providing minority educational opportunities in a knowledge based and globally diverse economy. However, they will face new and challenging budgetary and managerial reforms induced by the global financial crisis. As a result, they will be pressured to operate in the future with greater cost efficiency. Approach: Panel data pertaining to minority serving colleges and universities was used along with stochastic frontier analysis to provide cost inefficiency estimates over a four year academic period. Specification of an inefficiency component contained time varying institutional characteristics and influences, including a public Vs. private ownership control. Results: Minority College and university mean inefficiency was estimated to be approximately 1.24, indicating a 24% operation above the frontier cost. The study found that institutions achieved inefficiency reductions or efficiency gains in 2008-09 compared to 2005-06. The findings suggested that private institutions operated at greater inefficiencies relative to their publicly owned counterparts. However, the private sector laid claim to the most efficient institution, but also the most inefficient one. While the public minority serving colleges showed inefficiency deterioration over time, the findings point to private institution efficiency gains. Conclusion/Recommendations: A literature survey indicated that the study could be the first attempt at providing empirical estimates and subsequent insights into the operating cost efficiencies or inefficiencies of minority serving colleges and universities. The cost inefficiency findings suggested that these institutions did compare favorably in their managerial skills. However, as

    In empirical and theoretical criminology references to racism and ethnicity are commonplace, although much discussion has centred on the narrowly defined ‘race and crime’ debate. In an attempt to move beyond this debate, which is focused on whether certain ethnic minorities are over-represented in the prison population because of elevated rates of offending or because of discriminatory treatment in the criminal justice system, this paper proposes the formulation of minority perspectives in cr...

    Small and intermediate mass black holes should be expected in galactic nuclei as a result of stellar evolution, minor mergers and gravitational dynamical friction. If these minor black holes accrete as X-ray binaries or ultra-luminous X-ray sources, and are associated with star formation, they could account for observations of many low luminosity AGN or LINERs. Accreting and inspiralling intermediate mass black holes could provide a crucial electromagnetic counterpart to strong gravitational ...

    In the original Evolutionary Minority Game, a segregation into two populations with opposing preferences is observed under many circumstances. We show that this segregation becomes more pronounced and more robust if the dynamics are changed slightly, such that strategies with above-average fitness become more frequent. Similar effects occur also for a generalization of the EMG to more than two choices, and for evolutionary dynamics of a different stochastic strategy for the Minority Game.

    Full Text Available Background and Objectives: The prevalence of minor physical anomalies (prenatal errors of morphogenesis was evaluated in patients with Tourette syndrome to get indirect data on the possible role of aberrant neurodevelopment in the aetiology of Tourette syndrome. No published study is known on the minor physical anomaly prevalence in this recently intensively investigated disorder, and connecting to current opinions on a possible role of aberrant neurodevelopment in Tourette syndrome it seems important to introduce trait marker research focusing on brain maldevelopment. Methods: A scale developed by Méhes1,2 was used to detect the presence or absence of 57 minor physical anomalies in 24 patients with Tourette syndrome and in 24 matched controls 21 boys and 3 girls were evaluated, the age of onset of illness among the Tourette patients was between the age of 5 and 13. Results: The mean value of all minor physical anomalies was significantly higher among the group of patients compared with controls. (Mann - Whitney U - value: 49, 50, -Z = - 4,92, p = 0,001 In the case of 7 minor physical anomalies we could demonstrate statistically significant differences between the Tourette and the control sample. In the case of 4 minor malformations (supernumary nipples, prominent forehead, tongue with smooth and rough spots, double posterior hair whorl and of 3 phenogenetic variants (antimongoloid slant, inner epicanthic folds, high arched palate a significantly higher frequency was observed compared with control individuals. However after Bonferroni correction for the Fisher’s Exact test, only double posterior hair whorl and high arched palate showed a significantly higher frequency compared to control children (p = 0.001. Conclusions: The overrepresentation of minor physical anomalies in Tourette syndrome can strongly support the view that this disorder is related to pathological factors operating early in development.

  19. We Can Recruit Minorities Into The Geosciences

    2011-12-01

    Despite the dismal numbers, efforts to recruit minorities into the geosciences are improving, thanks in part to NSF's "Opportunities for Enhancing Diversity in the Geosciences" (OEDG) initiative. At Wesleyan University, a small liberal arts college in Connecticut, we have significantly increased our recruitment of minority students. Twenty percent (four students) of the class of 2013 are African American. Most of the recruitment is done on an individual basis and working in conjunction with the "Dean for Diversity and Student Engagement" and courting minority students in introductory classes. The Dean for Diversity and Student Engagement is aware of our interest in increasing diversity and that we are able to hire minority students during the academic year and through the summer with OEDG funds. When she identifies minority students who might be interested in the geosciences, she refers them to faculty in the Earth and Environmental Sciences Department. Our faculty can provide employment, mentoring and a variety of geo-related experiences. Courting students in introductory courses can include inviting them to lunch or other activity, and attending sports, theater or dance events in which they are participating. Not all efforts result in new majors. Courses in ancillary sciences may be stumbling blocks and higher grades in less demanding courses have lured some students into other majors. Nevertheless, we now have a large enough cohort of minority students so that minority students from other majors visit their friends in our labs. A critical mass? Even a student, who chooses another major, may continue an interest in geoscience and through outreach efforts and discussions with younger family members, may provide a bridge that becomes a conduit for future students.

    Background: Ice hockey has one of the highest sport participation and injury rates in youth in Canada. Body checking (BC) is the predominant mechanism of injury in leagues in which it is permitted. The objectives of this study were to determine whether the incidence and types of physical contact differ for Bantam players (aged 13–14 years) who were exposed to BC at Pee Wee level (aged 11–12 years) in Calgary, Alberta versus Bantam players who were not exposed to BC at Pee Wee level in Québec City, Québec. All teams were exposed to BC at bantam level; Methods: A cohort study was conducted in Québec City and Calgary. Sixteen games for Calgary and 15 for Québec City were randomly selected and analysed with a validated observation system to quantify five intensities of physical contact and to observe different types of physical contact such as slashing and holding; Results: A total of 5610 incidences of physical contact with the trunk and 3429 other types of physical contact were observed. Very light intensity trunk contact was more frequent in Calgary (adjusted incidence RR (ARR): 1.71; 95% CI: 1.28–2.29). Holding (ARR: 1.04; 95% CI: 1.02–1.07) and slashing (ARR: 1.38; 95% CI: 1.07–1.77) were more frequent in Calgary; Conclusion: Results suggest that players’ physical contacts differ between Bantam leagues in which BC was permitted at Pee Wee level and leagues in which it was not permitted until Bantam level.

    Full Text Available The breakdown of the former Yugoslavia has resulted in formation of new independent states while the former co-citizens and constitutive people have found themselves in new roles. Some have become a majority while some have become a minority, with an aspiration to affirm the status in the public sphere. As a country with a large numbers of immigrants from the former Yugoslavia, Slovenia is facing a challenge of the confirmation of ethnic pluralism within its borders, along with solutions and appropriate places for 'new' minorities (the usual appellation for ethnic groups formed by the members of the former Yugoslavia, where the Serbs are outnumbering the rest. At the same time, the new minorities face a challenge of constitution foundation of their own associations, that is, formation of their own identity and public affirmation in the new context. This paper discusses these ongoing processes with a special attention to the Serbian ethnic group.

    In this paper we study the continuum time dynamics of a stock in a market where agents behavior is modeled by a Minority Game with number of strategies for each agent S=2 and "fake" market histories. The dynamics derived is a generalized geometric Brownian motion; from the Black&Scholes formula the calibration of the Minority Game, by means of the game parameter $ \\sigma^{2}$, on the European options on DAX Index market is performed. An "$ (\\alpha,\\sigma^{2})$ -matrix" containing, given options' moneyness and maturities, values of the parameters $\\alpha$ and $ \\sigma^{2}$ that make the theoretical option price agree with the market price is constructed. We conclude that the asymmetric phase of the Minority Game with $\\alpha$ close to $\\alpha_c$ is coherent with options implied volatility market.

    2012-11-30

    Children absconding from countries of conflict and war are often not able to document their age. When an age is given, it is frequently untraceable or poorly documented and therefore questioned by immigration authorities. Consequently many countries perform age estimations on these children. Provision of ethical practice during the age estimation investigation of unaccompanied minors is considered from different angles: (1) The UN convention on children's rights, formulating specific rights, protection, support, healthcare and education for unaccompanied minors. (2) Since most age estimation investigations are based on medical examination, the four basic principles of biomedical ethics, namely autonomy, beneficence, non-malevolence, justice. (3) The use of medicine for non treatment purposes. (4) How age estimates with highest accuracy in age prediction can be obtained. Ethical practice in age estimation of unaccompanied minors is achieved when different but related aspects are searched, evaluated, weighted in importance and subsequently combined. However this is not always feasible and unanswered questions remain.

    1985-12-01

    This article arises from fieldwork in a school of the German minority in South Jutland, Denmark. The minority exists as a result of frontier changes between Germany and Denmark, most recently in 1920. A referendum held in that year as a result of the Treaty of Versailles left a cultural and linguistic minority which, by today, has its own school system, politial party and cultural rights. The research was carried out using qualitative, ethnographic methods and the article focuses on one aspect, namely the issue of language use by bilingual pupils in one of the minority's schools. Pupils' choice of Danish or German in different situations within and outside schools was analyzed through the use of language diaries, informal interviews, and participant observation. The diary entries are analyzed and commented on in the light of interviews and observations. Pupils' awareness of their language use is not static but becomes dynamic as a consequence of being involved in research. The implications of this for educational policy are considered in the context of current developments in language education in British schools.

The influence of the social networks like instrument of communication is not exempt from risks for the quantity of information that is facilitated and is shared. The lack of a specific regulation that he contemplates from the point of view of the Law which is the protection that a minor must have, does that there take place situations of abandonment of the rights of the same ones.The opportunity of regulation has been left to escape in the future law of protection of the infancy, nowadays in phase of preliminary design, since it does not refer to the social networks since it had been desirable. The current procedure as for minors, as well as those of protection of information, between others, do not turn out to be sufficient to contemplate all the situations of risk that can be given in the above mentioned area. In the present work we propose to think on minors and social networks raising some legal questions, and trying to contribute some response to the problematics that appears in the juridical area.

  13. Multiculturalism and legal autonomy for cultural minorities

    Directory of Open Access Journals (Sweden)

    Morten Ebbe Juul Nielsen

    2013-11-01

    Full Text Available Does multiculturalism imply that certain cultural minorities – nomos groups, whose cultural conceptions extend in important ways into views about the law – should have forms of legal autonomy that go beyond normal multicultural accommodations such as exemptions and special protection? In other words: should we allow «minority jurisdictions» for multicultural reasons and give certain minorities powers of legislation and adjudication on certain issues? The paper sketches how one might arrive at such a conclusion given some standard multicultural reasoning, and then proceeds by examining eight key rejoinders to such a proposal. None of these rejoinders provide by themselves knockdown arguments against extending multicultural rights to forms of legal autonomy, but together they do provide a basis for some skepticism about the cogency and desirability of at least more ambitious forms of legal autonomy for cultural minorities within a liberal framework.http://dx.doi.org/10.5324/eip.v7i2.1798

    Aleksandar Čorni

    2016-09-01

    Full Text Available The article tries to explore the practical application of the soft law, in concrete terms, the documents adopted by the Organization for Security and Co-operation in Europe, referring to the models of participation of national minorities in public life in the case of Bosnia and Herzegovina. The objective of the research was to assess the legal and political grounds for functioning national minority councils as participation and consultative mechanisms, scope of responsibilities and capacities in relation to their effectiveness and impact and to identify relevant good practices on such mechanisms. The political and decision-making structures in Bosnia and Herzegovina demonstrated lack of actual commitment to the realization of the rights of minorities referring to participation in decision-making processes. Bearing in mind formal position within parliaments, visibility, and a significant promotional capacity for presence in the public sphere, the councils on national minorities may represent a significant body and channel for the minority – majority dialogue. However, at the moment, the national minority councils’ capacity to ensure participation of national minorities in Bosnian political life and their influence in decision-making process remains insufficient. In general, the consultative mechanisms, within their mandated responsibilities, have had insignificant and minimal impact on the practical, political and legislative segment.

  19. Quantum annealing correction with minor embedding

    2015-10-01

    Quantum annealing provides a promising route for the development of quantum optimization devices, but the usefulness of such devices will be limited in part by the range of implementable problems as dictated by hardware constraints. To overcome constraints imposed by restricted connectivity between qubits, a larger set of interactions can be approximated using minor embedding techniques whereby several physical qubits are used to represent a single logical qubit. However, minor embedding introduces new types of errors due to its approximate nature. We introduce and study quantum annealing correction schemes designed to improve the performance of quantum annealers in conjunction with minor embedding, thus leading to a hybrid scheme defined over an encoded graph. We argue that this scheme can be efficiently decoded using an energy minimization technique provided the density of errors does not exceed the per-site percolation threshold of the encoded graph. We test the hybrid scheme using a D-Wave Two processor on problems for which the encoded graph is a two-level grid and the Ising model is known to be NP-hard. The problems we consider are frustrated Ising model problem instances with "planted" (a priori known) solutions. Applied in conjunction with optimized energy penalties and decoding techniques, we find that this approach enables the quantum annealer to solve minor embedded instances with significantly higher success probability than it would without error correction. Our work demonstrates that quantum annealing correction can and should be used to improve the robustness of quantum annealing not only for natively embeddable problems but also when minor embedding is used to extend the connectivity of physical devices.

    The intermittent critical velocity (ICV) test is used to quantify the relationship between velocity and time to exhaustion, yielding an aerobic parameter (ICV), an anaerobic parameter (anaerobic running capacity [ARC]), and critical rest interval (CRI). Critical rest interval is the theoretical rest period needed to maintain repeated bouts of exercise for an extended period of time without inducing fatigue during intermittent treadmill running. Fourteen collegiate, club-level male participants (mean ± SD; age: 21.4 ± 1.8 years; weight: 82.8 ± 5.9 kg; body fat: 11.8 ± 5.4%; and VO2max: 51.2 ± 2.8 ml · kg · min), primarily hockey and rugby players, completed the ICV test, using 15-second repeated sprints to exhaustion during separate sessions of treadmill running at varying supramaximal intensities. The time and total distance for each running session were used to determine ICV and ARC via linear regression. The CRI was calculated using the relationship between total distance during the ICV test and the number of intervals completed. Mean ICV and ARC (± SD) values were calculated as 4.80 ± 0.3 m · s and 154.1 ± 36 m, respectively. The mean ICV values were significantly different from the mean peak velocity (± SD) (4.67 ± 0.17 m · s) achieved during the VO2max test (p = 0.011). The CRI was calculated as mean ± SD: 33.9 ± 1.9 seconds. Body fat percentage measured by air displacement plethysmography (BOD POD®; r = -0.649; p = 0.012), lean body mass (r = -0.556; p = 0.039), fat mass (r = -0.634; p = 0.015), body weight (r = -0.669; p = 0.006), and relative VO2max (r = 0.562; p = 0.036) were significantly correlated with ICV. The ARC (r = 0.804; p = 0.001) and velocity at ventilatory threshold (r = -0.630; p = 0.016) were significantly correlated with CRI. The ability to quantify CRI, an additional variable derived from the ICV test, provides a possible measure that can be used in the prescription and evaluation of training methods.

  1. Tidal Tales of Minor Mergers: Star Formation in the Tidal Debris of Minor Mergers

    CERN Document Server

    Knierman, Karen A

    2009-01-01

    How does the tidal debris of minor galaxy mergers contribute to structures in spiral galaxies or in the intergalactic medium? While major mergers are known to create structures such as tidal dwarf galaxies and star clusters within their tidal debris, less is known about minor mergers (mass ratios between a dwarf galaxy and disk galaxy of less than one-third) and their tidal debris. This work surveys 6 nearby minor mergers using optical broad-band and H-alpha narrow-band imaging to characterize star formation in their tidal debris. Young star clusters with ages less than the dynamical age of the tidal tails are found in all 6 mergers, indicating that the star clusters formed in situ. Even if minor mergers contribute less tidal debris per interaction than major mergers, they are more common and possibly contribute structure to all types of galaxies and to the intergalactic medium throughout the history of the universe.

    Wood, M.T.; Radford, M.L.; Saari, L.M.; Wright, J.

    1986-04-01

    The focus of this investigation was to identify issues central to increasing the involvement of small minority businesses (MBs) in federal or prime contracts with the Department of Energy (DOE), as a foundation for designing a program to assist buyers of contracted goods and services. The approach to determining issues involved interviewing the owners of 15 MBs, representing a range of businesses, and buyers and purchasing officers from three large DOE prime contractors. The interviewees identified issues related to positive working relationships and rated a predetermined set of 27 potential MB-DOE problems regarding their existence and criticalness. The issues identified by MBs were of two broad types. The predominant issues and barriers were associated with their being small businesses. Secondary issues reflected the disadvantaged status of the business (woman and/or minority-owned).

    Vibration of a bridge structure due to the passage of vehicles is an important consideration in the design of bridges. Further, a common problem in bridge engineering practice in these years is the upgrading of minor highway bridges (=5-20 m) to carry heavier loads partly due to a tendency...... of heavier trucks moving at larger speeds, and partly because the authorities want to permit transportation of special heavy goods at a larger part of the road net. These needs will in many cases cause the strengthening of the bridges becomes necessary. In order to keep the expenses of such strengthening...... the results obtained using the numerical models given in details in "Heavy Vehicles on Minor Highway Bridges : dynamic modelling of vehicles and bridges".

    2009-04-01

    Full Text Available Abstract Previous studies about unaccompanied refugee minors (URMs showed that they are a highly vulnerable group who have greater psychiatric morbidity than the general population. This review focuses on mental health issues among URMs. Articles in databases PsycINFO, Medline and PubMed from 1998 to 2008 addressing this topic were reviewed. The literature had a considerable emphasis on the assessment of PTSD symptoms. Results revealed higher levels of PTSD symptoms in comparison to the norm populations and accompanied refugee minors. In several studies, age and female gender predicted or influenced PTSD symptoms. The existing literature only permits limited conclusions on this very hard to reach population. Future research should include the analysis of long-term outcomes, stress management and a more thorough analysis of the whole range of psychopathology. Additionally, the development of culturally sensitive norms and standardized measures for diverse ethnic groups is of great importance.

  12. Natural Minor Scale is More Natural to the Brain than Harmonic Minor Scale as Revealed by Magnetoencephalography

    Science.gov (United States)

    Ando, Hiromitsu; Nemoto, Iku; Oda, Shoichiro

    Minor mode is known to elicit stronger emotional responses than major mode in the brain. The present work focused on the minor scales and natural and harmonic minor scales were compared in automatic brain responses in an oddball paradigm. The standard stimulus was either the natural or harmonic minor scale, and a deviant stimulus lacked one scale tone of the corresponding complete minor scale. The brain responded to omission of every tone but omission of the tone B flat in the natural minor experiment elicited larger response than that of the other tones. In particular, the response was significantly larger than that to omission of B in the harmonic minor experiment. This result suggested that the brain felt the natural minor scale to be actually more natural than the harmonic minor scale.

    With more and more applications appearing and the technology developing in the Internet, only relying on terminal system can not satisfy the complicated demand of QoS network. Router mechanisms must be participated into protecting responsive flows from the non-responsive. Routers mainly use active queue management mechanism (AQM) to avoid congestion. In the point of interaction between the routers, the paper applies minority game to describe the interaction of the users and observes the affection on the length of average queue. The parameters α, β of ARED being hard to confirm, adaptive RED based on minority game can depict the interactions of main body and amend the parameter α, β of ARED to the best. Adaptive RED based on minority game optimizes ARED and realizes the smoothness of average queue length. At the same time, this paper extends the network simulator plat - NS by adding new elements. Simulation has been implemented and the results show that new algorithm can reach the anticipative objects.

  14. Axonal change in minor head injury.

    Povlishock, J T; Becker, D P; Cheng, C L; Vaughan, G W

    1983-05-01

    Anterograde axonal transport of horseradish peroxidase (HRP) in selected cerebral and cerebellar efferents was studied in cats subjected to minor head injury. After trauma, the animals were allowed to survive from one to 24 hours, when they were perfused with aldehydes and processed for the light and electron microscopic visualization of the peroxidase reaction product. By light microscopy, the brain injury elicited an initial intra-axonal peroxidase pooling. With longer post-traumatic survival, HRP pooling increased in size, demonstrated frequent lobulation, and ultimately formed large ball- or club-like swellings which suggested frank axonal separation from the distal axonal segment. Ultrastructural examination revealed that the initial intra-axonal peroxidase pooling was associated with organelle accumulation which occurred without any other form of axonal change or related parenchymal or vascular damage. This accumulation of organelles increased with time and was associated with conspicuous axonal swelling. Ultimately these organelle-laden swellings lost continuity with the distal axonal segment and the axonal swelling was either completely invested by a thin myelin sheath or protruded without myelin investment into the brain parenchyma. This study suggests that axonal change is a consistent feature of minor head injury. Since these axonal changes occurred without any evidence of focal parenchymal or vascular damage, minor brain injury may ultimately disrupt axons without physically shearing or tearing them.

    2015-01-01

    The use of Smartphones in teaching and learning is transforming academia and affords a shift in paradigm for Historically Black Universities and Colleges (HBCUs) nurse programs for the 21st century. Smartphone use in academic settings has gained popularity among college students. For minority and low-income students, this handheld device may be the only source to real-time Internet-accessible information, and in anchoring social, vocational, and academic habits. Nursing faculty acceptance of smartphones in the classroom assists in clinical and simulation learning experiences. These experiences are keys to integration of successful smartphone initiatives in HBCU nursing programs. PMID:26665502

  15. ISLAM AND MINORITIES: Managing Identity in Malaysia

    Directory of Open Access Journals (Sweden)

    Ahmad Suaedy

    2010-02-01

    Full Text Available The Malaysian general election in March 2008 raised an interesting and new phenomenon. For the first time since independence in 1957, the ruling alliance known as the National Front (Barisan Nasional, BN failed to secure two thirds of seats in parliament and lost control of five of Malaysia’s 13 states. This was due to the challenge presented by the new opposition alliance known as the Alternative Front (Barisan Alternatif, BA or the People’s Alliance (Pakatan Rakyat, PK which won more than 36% of seats in parliament and gained control of the five states. In the 2004 election, BN secured the largest ever percentage of seats in parliament with 91%. What is interesting is that it seems that this significant increase in support for the opposition is  due to their offer to change the way minorities and ethnicity is managed. They  propose a move from “Bumiputera Supremacy”, or affirmative action for the approximately 65% of “Bumiputera” Malaysians (the rest being largely of Chinese or Indian ethnicity, to “The People’s Supremacy”, which involves eradicating affirmative action based on ethnicity, basing it instead on need, for  instance need due to poverty. This would potentially increase the likelihood  of justice and equality for all ethnic or racial groups. This paper connects the phenomenon of change, as seen in the about turn in the results between the  2004 and 2008 elections, to the more global trend in which minorities are standing up to demand their rights in this era of globalization, and to the challenge multiculturalism presents to parts of the Muslim world such as Malaysia. Malaysia, a Muslim majority nation that has formally declared Islam the official state religion with Yang di-Pertuan Agong (the King as  Head of the State and symbol of Islam, is one example, though not necessarily  representative, of how Islam and Muslims manage minorities and identity or  multiculturalism within the process of globalization

    In this paper, we present our approach for the study of the complexity of Minority Game using tools from thermodynamics and statistical physics. Previous attempts were based on the behavior of volatility, an observable of the financial markets. Our approach focuses on some properties of the binary stream of outcomes of the game. Physical complexity, a magnitude rooted in Kolmogorov-Chaitin theory, allows us to explain some properties of collective behavior of the agents. Mutual information function, a measure related to Shannon's information entropy, was useful to observe a kind of phase transition when applied to the binary string of the whole history of the game.

    in Denmark, the paper challenges the myths about intergenerational care. The concept of intersectionality emphasises that the older adults are simultaneously positioned within the social categories such as gender, ethnicity and social class, along with directing attention to processes of exclusion as well...... such as gender ideals. However, the filial responsibility norms are still prevalent, in spite of the social care and provision of welfare by the Danish state.......This paper deals with the dynamics of ageing among ethnic minorities within a broad psychosocial framework involving the transnational contexts.

    2011-01-01

    Game theory is the mathematical framework for analyzing strategic interactions in conflict and competition situations. In recent years quantum game theory has earned the attention of physicists, and has emerged as a branch of quantum information theory [1]. With the aid of entanglement and linear superposition of strategies, quantum games are shown to yield signifcant advantage over their classical counterparts. In this paper we explore optimal and equilibrium solutions to quantum minority games. Initial states with different level of entanglement are investigated. Focus will be on 4 and 6 player games with some N-player generalizations.

  5. Trabectedin – the DNA minor groove binder

    Directory of Open Access Journals (Sweden)

    G. A. Belitsky

    2015-01-01

    Full Text Available Trabectedin (ET-743, Yondelis is an alkaloid that was originally isolated from the Caribbean Sea squirt, Ecteinascidia turbinata and is now produced synthetically. Its chemical structure consists in three fused tetrahydroisoquinoline rings. Two of them, A and B, binds covalently to guanine residues in the minor groove of the DNA double helix to bend the molecule toward the major groove and the third ring C protrudes from the DNA duplex, apparently allowing interactions with several nuclear proteins. Binding to the minor groove of DNA, trabectedin trigger a cascade of events that interfere with several transcription factors, DNA binding proteins, and DNA repair pathways in particular nucleotide excision repair. It acts both as a DNA-alkylating drug and topoisomerase poison. Trabectedin-DNA adduct traps the nucleotide excision repair proteins repairing the DNA damage in transcribing genes and induces DNA strand breaks. Cells deficient in homologous recombination pathway which repairs these double-strand breaks show increased sensitivity to trabectedin. The most sensitive of them were myxoid liposarcomas. Trabectedin is also effective in chemotherapy-experienced patients with advanced, recurrent liposarcoma or leiomyosarcoma as well as in women with ovarian cancer and breast cancer with BRCAness phenotype. Besides of tumor cells Trabectedin inhibits inflammatory cells by affecting directly monocytes and tumorassociated macrophages and indirectly by inhibiting production of inflammatory mediators, the cytokines and chemokines. It inhibits also the MDR-1 gene, which is responsible for the resistance of cancer cells to chemotherapeutic agents and strikes tumor angiogenesis.

    Queensborough Community College (QCC) and Medgar Evers College (MEC) of the City University of New York have been actively involved in recruiting primarily minority students to the Geosciences by involving students in research and by incorporating innovative and proven pedagogical methods into the classroom. Students at both colleges have been actively involved in doing research in Space and Earth Science. Students work during the summer under the mentorship of CUNY faculty conducting experiments and analyzing data. At the end of the summer students present findings at various science meetings. In the lecture room, the method of instruction was modified to emphasize active learning. Educational materials and pedagogical methods developed at QCC and other 4 year colleges was introduced to the predominantly minority student body at QCC and MEC. Many of these students did poorly at pre-college schools where lecture based learning is the chief method of instruction. It is not unexpected that many of them are having difficulty if the method of instruction has not changed at the postsecondary level. The intent of introducing active learning was to have students develop an appreciation of science, and have an increased understanding of relevant scientific principles. As a result of these activities student scores increased as compared to student scores in a more affluent college. Students also demonstrated increased conceptual understanding of the material, had higher self- efficacy scores, and seemed to enjoy the class better. Lower scoring students demonstrated the greatest benefit, while the better students had little (or no) changes.

    Margot, J. L.

    2004-11-01

    The discovery of binary systems in the near-Earth, main belt, and Kuiper belt populations provides an abundance of new data that expand our knowledge of the physics and chemistry of the solar system. Binary minor planets form as a result of collisional, tidal, and capture processes that are important to study as they play major roles in the formation and evolution of planetary systems. The frequency of occurrence of such processes directly reflects the dynamical environment in the various populations. Observations of binaries provide a powerful way to measure the bulk properties of small bodies, which in turn lead to inferences about their composition and internal structure. These data may offer a rare glimpse of what physical and chemical conditions prevailed when protoplanets formed, and what subsequent evolution took place. In the case of the Kuiper Belt, the study of a handful of binaries forces us to rethink how dense and how bright these bodies are, and to significantly revise our current mass estimates for the entire population. The number of known binary minor planets has increased dramatically over the past few years, with roughly ten new discoveries each year. I will attempt to summarize recent developments, with examples drawn from my observations with the Hubble, Palomar, Keck, Arecibo and Goldstone telescopes.

  8. Minority games, evolving capitals and replicator dynamics

    International Nuclear Information System (INIS)

    We discuss a simple version of the minority game (MG) in which agents hold only one strategy each, but in which their capitals evolve dynamically according to their success and in which the total trading volume varies in time accordingly. This feature is known to be crucial for MGs to reproduce stylized facts of real market data. The stationary states and phase diagram of the model can be computed, and we show that the ergodicity breaking phase transition common for MGs, and marked by a divergence of the integrated response, is present also in this simplified model. An analogous majority game turns out to be relatively void of interesting features, and the total capital is found to diverge in time. Introducing a restraining force leads to a model akin to the replicator dynamics of evolutionary game theory, and we demonstrate that here a different type of phase transition is observed. Finally we briefly discuss the relation of this model with one strategy per player to more sophisticated minority games with dynamical capitals and several trading strategies per agent

    Pendragon, Diane K

    2010-01-01

    This article summarizes data from a qualitative study investigating the ways in which female youth perceive and respond to challenges related to the interplay of late adolescence and a minority sexual orientation. Fifteen sexual minority females in late adolescence were interviewed individually and in focus groups. The interviews focused on participants' perceptions of challenges, the impact those stressors have in their lives, and methods they utilize to cope with them. The most common negative experiences reported were isolation, lack of acceptance, harassment, and violence. Sub-themes include: hearing negative messages about gender and sexual orientation, pressures to conform to a variety of cultural norms including gender norms, fears of future violence, and pressure to identify sexual orientation. Collectively, the participants described these negative consequences of experiences of heterosexism, sexism, and racism as their most difficult experiences. The most common responses to these stressors reported by participants were finding support in relationships, engaging in coping responses, pursuing education and activism, rebellion and resistance, and avoidance and deferment.

    Since 1971, the American Geological Institute (AGI) Minority Participation Program (MPP) has supported scholarships for underrepresented minorities in the geosciences at the undergraduate and graduate levels. Some of our MPP scholars have gone on to hugely successful careers in the geosciences. MPP scholars include corporate leaders, university professors, a NASA scientist-astronaut and a National Science Foundation (NSF) CAREER awardee. Yet as ethnic minorities continue to be underrepresented in the geosciences, AGI plans to expand its efforts beyond its traditional undergraduate and graduate scholarships to include diversity programs for secondary school geoscience teacher internships, undergraduate research travel support, and doctoral research fellowships. Funding for the MPP has come from multiple sources, including industry, scientific societies, individuals, and during the last 10 years, the NSF. College-level students apply for the MPP awards or award renewals, and the MPP Advisory Committee selects scholarship recipients based upon student academic performance, financial need, and potential for success as a geoscience professional. Mentoring is a long-standing hallmark of the AGI MPP. Every AGI MPP scholar is assigned a professional geoscientist as a mentor. The mentor is responsible for regular personal contacts with MPP scholars. The MPP Advisory Committee aims to match the profession of the mentor with the scholar's academic interest. Throughout the year, mentors and scholars communicate about possible opportunities in the geosciences such as internships, participation in symposia, professional society meetings, and job openings. Mentors have also been active in helping younger students cope with the major changes involved in relocating to a new region of the country or a new college culture. We believe that AGI is well-positioned to advance diversity in the geosciences through its unique standing as the major professional organization in the

    Directory of Open Access Journals (Sweden)

    1998-03-01

    Full Text Available In this article the introductory part deals with Christian guidelines regarding the rights of minority groups. In the ensuing part the provision of education according to the unique educational needs of minority groups is discussed within the context of the presented guidelines. It is indicated that own education is internationally accepted as one of the major rights of minority groups. Within the international context, for example in the treaties of Unesco and in the educational provision of several countries, it is accepted that minority groups also prefer their own education institutions in order to effectively provide in their unique educational needs. In this article the more general requirements, regarding the characteristics of the education institution needed to meet the unique educational needs of a particular minority group are also identified. The impending problems in South Africa regarding own education schools for minorities are discussed briefly. In order to find possible solutions the situation in the Netherlands regarding "bijzondere scholen” to provide in the unique educational needs of particular interest groups and particularly religious groups is analysed. The conclusion arrived at is that the mentioned situation does not oppose Christian guidelines if minorities need each other to influence educational change, that the acknowledgement of the educational rights of minority groups promotes national unity, that the educational rights of minorities should imply freedom of establishment, denomination and institution and that the educational rights of minorities are fully realised if their education is financially supported by government on an equal basis to that of the majority.

    2006-01-01

    @@ We study a model of local minority game in the random Kauffman network with evolutionary strategies and propose three methods to update the strategy of poor agents, with lower points in a given generation: namely to update either the Boolean function of their strategies randomly, or their local information of randomly adjacent m agents, or the number m of randomly chosen adjacent agents. The results of extended numerical simulations show that the behaviour of strategies in the three methods may enhance significantly the entire coordination of agents in the system. It is also found that a poor agent tends to use both small m strategies and correlated strategies, and the strategies of agents will finally self-organize into a steady-state distribution for a long time playing of the game.

  19. Autochthonous Linguistic Minorities in the Italian Alps:

    Directory of Open Access Journals (Sweden)

    Ernst Steinicke

    2011-08-01

    Full Text Available More than any other area in Western Europe, the Alps, especially the Italian Alps, are home to great ethno-cultural diversity: there, no less than seven autochthonous linguistic minorities coexist side by side with the respective official majority. Now being considered an important cultural heritage by the state as well as by the regions, new legislation offers protection to all ‘linguistic-historic minorities’ in Italy. Our study shows, however, that it is quite difficult to maintain such groups, since it is largely unknown where exactly the minority areas are situated. Based on that, local actor groups in various communities take advantage of this lack of knowledge and declare themselves minority territories although they show no linguistic varieties. An important objective of this project is therefore to present a cartographic representation of this linguistic diversity. Subsequently, the contribution discusses case studies of distinct ethno-linguistic self-awareness. Even though with Law No. 482 a first important step was taken to preserve the linguistic minorities, their progressive decline by territorial and numerical criteria cannot be denied. Today, besides unfavorable bio-demographic factors and “diffuse ethnicity,” other causes are current demographic processes. In this framework the amenity migrants, those new immigrants who have discovered the mountains as a new, desirable settlement space, play a decisive role by reinforcing the assimilation process.Les Alpes, plus précisément les Alpes italiennes, plus que toute autre région d'Europe Occidentale, sont un lieu de grande diversité ethnoculturelle : pas moins de sept minorités linguistiques autochtones y coexistent, côte à côte avec la majorité officielle correspondante.

    Vibration of a bridge structure due to the passage of vehicles is an important consideration in the design of bridges. Further, a common problem in bridge engineering practice in these years is the upgrading of minor highway bridges (=5-20 m) to carry heavier loads partly due to a tendency...... of heavier trucks moving at larger speeds, and partly because the authorities want to permit transportation of special heavy goods at a larger part of the road net. These needs will in many cases cause the strengthening of the bridges becomes necessary.

  2. Controlling herding in minority game systems

    CERN Document Server

    Zhang, Ji-Qiang; Wu, Zhi-Xi; Su, Riqi; Lai, Ying-Cheng

    2015-01-01

    Resource allocation takes place in various types of real-world complex systems such as urban traf- fic, social services institutions, economical and ecosystems. Mathematically, the dynamical process of complex resource allocation can be modeled as minority games in which the number of resources is limited and agents tend to choose the less used resource based on available information. Spontaneous evolution of the resource allocation dynamics, however, often leads to a harmful herding behavior accompanied by strong fluctuations in which a large majority of agents crowd temporarily for a few resources, leaving many others unused. Developing effective control strategies to suppress and elim- inate herding is an important but open problem. Here we develop a pinning control method. That the fluctuations of the system consist of intrinsic and systematic components allows us to design a control scheme with separated control variables. A striking finding is the universal existence of an optimal pinning fraction to mi...

  3. Multiplayer quantum Minority game with decoherence

    CERN Document Server

    Flitney, A P; Flitney, Adrian P.; Hollenberg, Lloyd C. L.

    2005-01-01

    A quantum version of the Minority game for an arbitrary number of agents is studied. When the number of agents is odd, quantizing the game produces no advantage to the players, however, for an even number of agents new Nash equilibria appear that have no classical analogue. The new Nash equilibria provide far preferable expected payoffs to the players compared to the equivalent classical game. The effect on the Nash equilibrium payoff of reducing the degree of initial entanglement between the players' qubits or of introducing various forms of decoherence is discussed. As the number of players increases the multipartite GHZ state becomes increasingly fragile, as indicated by the smaller error probability required to reduce the Nash equilibrium payoff to the classical level.

    2016-01-01

    The number of unaccompanied immigrant minors (UIMs) from Central America significantly increased in 2014. Nearly 50,000 children from El Salvador, Guatemala, and Honduras crossed the United States-Mexico border in 2014, compared with 3,933 in 2011. Few resources exist to guide pediatric nurse practitioners (PNPs) in their care of UIM. The multifactorial reasons behind migration and the state of children's health in Central America provide insight into the needs of UIMs. Guidelines for similar groups such as foreign-born children and refugees offer direction for the health care considerations of UIMs. This article provides demographic information on UIMs, highlights the unique and challenging medical and mental health issues facing UIMs, and discusses the role of the PNP. A UIM's initial visit with a PNP serves as an opportunity to build trust through culturally competent, trauma-informed care, provide preventive care, assess for unmet health needs, and screen for mental health conditions.

  5. Minor and trace inorganic components of toothpastes

    International Nuclear Information System (INIS)

    Elements present in minor or trace quantities in various toothpastes available in Scandinavia have been quantitatively assayed by means of emission spectrography and neutron activation analysis. The elements antimony, arsenic, mercury or selenium were observed at levels less than 2 parts/106. Boron, gallium, iron, magnesium, manganese and titanium occurred at levels between 0.001 and 1%. Cadmium, copper, lead, nickel and tin could not be identified. The detection limit for these elements amounted to 10 parts/106. The amounts of any of these elements which could be transferred to the body after swallowing toothpaste during brushing, have been compared with daily intake of similar elements through food and drinks, and found to be small compared to the diet intake except in the case of titanium. The intake of titanium from toothpaste could exceed the diet five times. (author)

      A connected $k$-chromatic graph $G$ is double-critical if for all edges $uv$ of $G$ the graph $G - u - v$ is $(k-2)$-colourable. The only known double-critical $k$-chromatic graph is the complete $k$-graph $K_k$. The conjecture that there are no other double-critical graphs is a special case of...... of a conjecture from 1966, due to Erd\\H{o}s and Lov\\'asz.  The conjecture has been verified for $k \\leq 5$.  We prove for $k=6$ and $k=7$ that any non-complete double-critical $k$-chromatic graph is $6$-connected and has $K_k$ as a minor.

    Over the past five years NASA has carried out a deliberate and highly successful effort to engage Minority Institutions (MI) in space science activities. Implemented through a uniquely designed grants program now known as the "NASA Minority University and College Education and Research Partnership Initiative (MUCERPI) in Space Science," an impressive array of space science research and educational activities has been developed at 15 MI's over the three-year period from January 1, 2001 to December 31, 2003. This effort began with the recognition that very few MI's had programs in space science. To address this deficiency, the NASA Office of Space Science (OSS), in cooperation with the NASA Office of Equal Opportunity Programs (OEOP), carried out a series of consultations with MI faculty and administrators aimed at ascertaining the level of interest that MI's had in space science and at identifying the most effective strategies for developing space science capabilities on their campuses. The clear conclusion was that MI's were extremely interested in participating in space science, but that they had not been given a real opportunity to do so. The overwhelming consensus was that a successful program to engage MI's in space science would require: 1) a serious invitation from OSS to become involved in space science, 2) the flexibility to devise projects that fit the local environment on each participating campus, and 3) the opportunity to form partnerships with leading researchers in the space science community. As a result, a NASA Research Announcement (NRA) emphasizing these and other factors was developed and issued in January 2000. Some of its more unique features were that: 1) it was issued by OSS with funding provided by OEOP; 2) it invited MI's to develop any combination of research capabilities, academic programs (at any level), and/or public outreach in space science; and 3) it required working partnerships with NASA-sponsored space science researchers for any

    Full Text Available Foot ulceration in diabetic patients is a frequent complication of diabetes mellitus (DM, necessitating hospitalization for control of infection, wound care and glycemic control. These patients are at risk for potential loss of the involved limb as well as for future loss of the contralateral limb. Diabetic foot is the consequence of peripheral neuropathy complicated by infrapopliteal peripheral vascular disease. Most of the patients present with chronic plantar ulceration and with cellulitis or an abscess. In a significant number of patients, it is observed that the frequency of life or limb threatening infection is less with an intact skin cover. Limb salvage employs the use of culture specific antibiotics, sharp debridement or a minor amputation, wound care and/or skin cover as the situation demands.

  11. Minor actinide transmutation on PWR burnable poison rods

    International Nuclear Information System (INIS)

    Highlights: • Key issues associated with MA transmutation are the appropriate loading pattern. • Commercial PWRs are the only choice to transmute MAs in large scale currently. • Considerable amount of MA can be loaded to PWR without disturbing keff markedly. • Loading MA to PWR burnable poison rods for transmutation is an optimal loading pattern. - Abstract: Minor actinides are the primary contributors to long term radiotoxicity in spent fuel. The majority of commercial reactors in operation in the world are PWRs, so to study the minor actinide transmutation characteristics in the PWRs and ultimately realize the successful minor actinide transmutation in PWRs are crucial problem in the area of the nuclear waste disposal. The key issues associated with the minor actinide transmutation are the appropriate loading patterns when introducing minor actinides to the PWR core. We study two different minor actinide transmutation materials loading patterns on the PWR burnable poison rods, one is to coat a thin layer of minor actinide in the water gap between the zircaloy cladding and the stainless steel which is filled with water, another one is that minor actinides substitute for burnable poison directly within burnable poison rods. Simulation calculation indicates that the two loading patterns can load approximately equivalent to 5–6 PWR annual minor actinide yields without disturbing the PWR keff markedly. The PWR keff can return criticality again by slightly reducing the boric acid concentration in the coolant of PWR or removing some burnable poison rods without coating the minor actinide transmutation materials from PWR core. In other words, loading minor actinide transmutation material to PWR does not consume extra neutron, minor actinide just consumes the neutrons which absorbed by the removed control poisons. Both minor actinide loading patterns are technically feasible; most importantly do not need to modify the configuration of the PWR core and

    Full Text Available The right of the Muslim minority of Western Thrace to receive education in the mother tongue is provided by the Treaty of Lausanne and the educational bilateral agreements-the Educational Agreement (1951 and the Cultural Protocol (1968-signed between Greece and Turkey. Due to certain particularities in the educational system, however, minority students do not have adequate opportunities to gain knowledge of the Greek or Turkish language. The major problems the Muslim minority faces in education include: a mixed system of administration, outdated textbooks, poorly-educated teaching staff and the absence of an efficient school curriculum. This article will provide a critical analysis of the existing legislation on education provided to Muslim students in the minority schools of Western Thrace. Secondly, an examination will be made of the level and status of minority education in light of current international human rights treaties documents for the protection of minorities. The existing inadequacies of the educational system will be addressed to provide a series of effective solutions and recommendations in favour of the advancement and improvement of education in minority schools. The article will therefore examine the principle that education needs to be made available and accessible at all levels to the member of a minority group and, most importantly, it needs to adapt to the socio-linguistic and cultural needs of minority students.

    Previous research indicates that lesbian, gay, and bisexual (LGB) adolescents are at increased risk for substance use, including heightened rates of marijuana use. Minority stress theory suggests that difficult social situations create a state of chronic stress that leads to poor health outcomes for LGB adults; however, the applicability of this model has not been well explored in relation to substance use among LGB adolescents. The current study is a secondary analysis of the OutProud survey, conducted in 2000. The original study used purposive sampling to collect data from 1,911 LGB adolescents (age 12-17) across the United States, and represents the largest known study to explore experiences specific to identifying as LGB, such as homophobia and gay-related victimization. We used structural equation modeling (SEM) to explore the feasibility of applying a minority stress framework to understand marijuana use in this population. The final structural model for marijuana use in the LGB adolescent sample displayed excellent fit and modest explanatory power for marijuana use. Two of the five factors, community connectedness and internalized homophobia, were significantly (p stress theory may be appropriately applied to marijuana use in this population; however, better measurement of minority stress concepts for LGB adolescents is needed.

    Using MCA-3C heart function information instrumentation, the influences of movement training on heart's tension-contraction speed and left ventricle function of the female hockey athletes are discussed. To take the general female university students (control group, n = 9), the sports education specialized female university student(sports education group, n=9) and the female hockey team athletes (women hockey team group,n= 9)as the object of study, under peaceful condition and different load condition, the biochemical indexs on systolic time interval(STI) are measured. Results demonstrate that the training may improve the trainer's heart function at rest through cutting the heart rate, lengthening LVET, reducing ICT and lengthening MST. The training may improve the trainer's heart function at different intensity movement through reduceing the HR increase rate, lengthening LVET, reducing lowintensity and the medium-intensity ICT, maintaining ICT stability when the high-intensity movement.The training can accelerate the trainer's HR restores, maintaining MST and EML stability, so it has the good function in recovery period.%利用MCA-3C心脏功能信息检测仪,探讨运动训练对心脏的张力-收缩速度及左心室功能的影响.以普通专业女大学生(对照组,n=9)、体育教育专业女大学生(体教组,n=9)和女子曲棍球队运动员(女曲组,n=9)为研究对象,测量其安静状态及40 W,80 W和120 W负荷蹬车3 min(转速为60 r/min)结束即刻、120 W恢复期第5 min和第10 min的心缩间期(STI)各项指标.结果表明,运动训练可改善训练者安静时心脏功能,通过降低HR,延长LVET,缩短ICT,延长MST来实现;运动训练可改善训练者运动时心脏功能,通过降低运动时HR上升幅度,延长LVET,缩短小强度及中等强度运动时ICT,维持大强度运动时ICT不再继续缩短来实现;运动训练对加速训练者运动后HR恢复,维持运动后恢复期MST及EML稳定具有良好的作用.

    Full Text Available V průběhu několika posledních let vzrostly možnosti jedinců s tělesným postiženým zapojit se do fyzických činností. Z tohoto důvodu je uznáván význam zvládnutí sportovních dovedností ještě před samotnou účastí v soutěžích. O stále oblíbenějším sledge hokeji bylo dosud provedeno málo výzkumů. Hlavní složkou výkonu je analýza dovedností. Vzhledem k její uznávané důležitosti a současnému nedostatku příslušných výzkumů na tomto poli jsme při této studii využili videozáznamů z paralympijského sledge hokejového turnaje z Turína v roce 2006, které nám poskytly možnost vytvořit protokol o pozorování s podrobnými kritérii toho, co utváří vyspělé profesionální sledge hokejové dovednosti. Proběhly konzultace s odborníky z tohoto odvětví a jejich zpětná vazba nám umožnila vytvořit tento nástroj. Po dokončení protokolu jsme provedli pilotní vyhodnocení, pro které byli hráči vybíráni na základě statistik z paralympijských her. Tito hráči byli poté pomocí našeho protokolu hodnoceni. Bylo prokázáno, že protokol dokáže úspěšně rozlišovat hráče vyšší a nižší úrovně. Over the past few years opportunities have been increasing for individuals with physical disabilities to become involved in physical activities; hence there is a recognition of the importance of mastering sport skills before participation. Currently there is little research that has been performed on the increasingly popular sport of sledge hockey. A major component of performance is skill analysis. Having recognised its importance and the current unavailability of relevant research in the area, this study used video recordings of the Torino 2006 Paralympic sledge ice hockey tournament to provide a setting in which to produce a skill observation protocol with detailed criteria of what constitutes a mature professional sledge ice hockey skill. Experts in the field were

    Resource allocation takes place in various types of real-world complex systems such as urban traffic, social services institutions, economical and ecosystems. Mathematically, the dynamical process of resource allocation can be modeled as minority games. Spontaneous evolution of the resource allocation dynamics, however, often leads to a harmful herding behavior accompanied by strong fluctuations in which a large majority of agents crowd temporarily for a few resources, leaving many others unused. Developing effective control methods to suppress and eliminate herding is an important but open problem. Here we develop a pinning control method, that the fluctuations of the system consist of intrinsic and systematic components allows us to design a control scheme with separated control variables. A striking finding is the universal existence of an optimal pinning fraction to minimize the variance of the system, regardless of the pinning patterns and the network topology. We carry out a generally applicable theory to explain the emergence of optimal pinning and to predict the dependence of the optimal pinning fraction on the network topology. Our work represents a general framework to deal with the broader problem of controlling collective dynamics in complex systems with potential applications in social, economical and political systems.

    Are plants generally less sensitive to toxicity than aquatic animals as indicated by some authors (1)? The use of phytotoxicity (higher plant) tests as a part of ecotoxicology is relatively underdeveloped. The objective of this study was to compare the results of the OECD Lemna Growth Inhibition Test with other mainly used test systems. Three toxicants were tested applying the Alga Growth Inhibition Test (Seleneastrum capricornutum), the Daphnia Immobilization Test (Daphnia magna) and the MICROTOX-test (Photobacterium phosphoreum). Duckweed plants were found to be sensitive to the chemicals tested, with nearly 100% inhibition of frond production occurring in the highest concentrations. The plants in some samples showed lesions (break up of the colony structure) and loss of green pigments (chlorosis), others showed localized dead tissues (necrosis). In addition to the morphological deviations (appearance) there is a wide range of characteristics to be observed on the test plants: number of fronds, number of plants, biomass, dry weight, mortality, CO2 and O2 exchange, concentration of chlorophyll a and chlorophyll b. It is consistent that the number of fronds is slightly more sensitive than or the same as the number of plants and that the biomass tend to be somewhat more tolerant than those for the number of plants (2). Applying the simplest way of observation, changes in the frond number were recorded. As Lemna minor show a characteristical sensitivity to the different kind of chemicals, it is a promising indicator of aquatic toxicity. PMID:10943492

  3. Nuclear data for plutonium and minor actinides

    International Nuclear Information System (INIS)

    Some experience in the usage of different evaluations of neutron constants for plutonium isotopes and minor actinides (MA) is described. That experience was obtained under designing the ABBN-93 group data set which nowadays is used widely for neutronics calculations of different cores with different spectrum and shielding. Under testing of the ABBN-93 data set through different integral and macroscopic experiments the main attention was paid to fuel nuclides and cross sections for MA practically did not verify. That gave an opportunity to change MA nuclear data for more modern without verification of the hole system. This desire appeared with new data libraries JENDL-3.2, JEF-2.2 and ENDF/B-6.2, which was not accessible under designing the ABBN-93. At the same time with the reevaluation of the basic MA nuclear data the ABBN-93 and the library FOND-2 of evaluated nuclear data files, which used as the basis for retrieving of the ABBN-93 data, were added with not very important MA data. So the FOND-2 library nowadays contents nuclear data files for all actinides with the half-life time more 1 day and also those MA which produce long-life actinides

    Full Text Available The Israeli Plonit case concerns a Muslim woman who wished to be represented by a female arbitrator in a Shari’a Court. The Shari’a Court of Appeals denied her request and decided that Shari’a Law permits only men to serve as arbitrators. Plonit petitioned the Israeli Supreme Court, which accepted her petition and decided that the Shari’a Court of Appeals’ decision infringed her right to equality. While I support the outcome of the Supreme Court’s decision, my paper sheds a light on a crucial matter that is absent in the decision; namely, the right to culture of Muslim women, who are a vulnerable members of a minority group in Israel, and therefore constitute a “minority within minority”. Analysing the case in terms of Plonit’s right to culture, in addition to her right to equality, has two advantages. First, it stresses the main issues at the heart of the legal debate, which are the minority culture’s norms and practices, and the right of the minority within the minority to influence and shape them as much as the majority within the minority. Second, when the minority within the minority’s claim is put in terms of the right to culture, and not only in terms of the right to equality, they are not necessarily perceived by other minority members as claims that try to enforce external norms on the minority culture.

    In ice hockey match,the scores are achieved by shoot,and the shoot skills can reflect a team's offensive capabilities and overall strength,be more the key of victory. With the statistics of the players' shoot skills in ice hockey men semi finals and finals in Sochi 2014 Winter Olympics,the paper finds out that the shoot skills of world power teams are more in pull-shot and slap-shot,less in scoop-shot and shovel-shot. Their shoot efficiency is not high,the highest shoot effeciency is only 74.19%of Canadian team,the lowest one is 70.96%of USA team. The most of teams' shoot positions are in offensive zone and the few in center or defensive zone. It hints that in the future,it's necessary to improve the effectiveness of shoot skills by enhancing the training of shovel-shot,scoop-shot and flip-shot.%冰球比赛的得分是通过射门实现的,射门技术情况能体现一个球队的进攻能力以及整体实力,更是能否赢得比赛的关键。通过对2014年索契冬奥会男子冰球半决赛、决赛射门技术情况的统计,发现:世界冰球强队队员射门技术中运用较多的依次是拉射、击射,运用较少的依次是弹射、垫射;射门有效率都不是很高,最高的加拿大队的射门有效率不过为74.19%,最低的是美国队射门有效率为70.96%;各队射门的位置绝大多数在前场区域,而很少部分在中场区和后场区。提示我们:在今后的训练中加强对垫射、挑射、弹射这三种射门技术的练习,并且需要提高射门的有效性。

  4. Transmutation of minor actinide using thorium fueled BWR core

    International Nuclear Information System (INIS)

    One of the methods to conduct transmutation of minor actinide is the use of BWR with thorium fuel. Thorium fuel has a specific behaviour of producing a little secondary minor actinides. Transmutation of minor actinide is done by loading it in the BWR with thorium fuel through two methods, namely close recycle and accumulation recycle. The calculation of minor actinide composition produced, weigh of minor actinide transmuted, and percentage of reminder transmutation was carried SRAC. The calculations were done to equivalent cell modeling from one fuel rod of BWR. The results show that minor actinide transmutation is more effective using thorium fuel than uranium fuel, through both close recycle and accumulation recycle. Minor actinide transmutation weight show that the same value for those recycle for 5th recycle. And most of all minor actinide produced from 5 unit BWR uranium fuel can transmuted in the 6th of close recycle. And, the minimal value of excess reactivity of the core is 12,15 % Δk/k, that is possible value for core operation

    2014-01-01

    This paper is interested in the way the concept of culture is deployed in documents aimed at investigating, informing on and promoting aspects of ethnic minority health. Within a health-political discourse focusing increasingly on individual lifestyles, ethnic minority health became subject...... to increased political and professional interest in the last decades of the twentieth and the first decade of the twenty-first century. Analysis of the discourse on ethnic minority health emerging in five texts addressing health professionals shows that the culture of ethnic minority citizens is primarily seen...... as contributing to low levels of knowledge about health and to adverse health behavior. Thus, the texts present cultural beliefs and practices as contributing to the high prevalence of lifestyle diseases among ethnic minority population groups. The analysis, however, demonstrates that a more nuanced discourse...

  17. EU minority protection: A modest case for a synergetic approach

    Directory of Open Access Journals (Sweden)

    Dimitry Kochenov

    2012-02-01

    Full Text Available In a stark contrast with the dominant minority-protection literature in the EU this paper proposes a synergetic approach to minority protection in the Union, acknowledging that attempts to draw clear distinctions between different minority groups on the basis of a number of criteria can be profoundly unhelpful and is able to undermine the efforts to improve the lives of Europeans belonging to the most vulnerable groups. Such synergetic approach provides a solid point of departure for the discussion of the problems in the area of minority protection that the EU is facing, which is the main focus of the paper. It is argued that theorizing minority protection can only result in the sound resolution of outstanding problems if unnecessary compartmentalization of the vulnerable groups is avoided.

  18. Minor lipophilic compounds in edible insects

    Full Text Available Contemporary society is faced with the question how to ensure suffiecient nutrition (quantity and quality for rapidly growing population. One solution can be consumption of edible insect, which can have very good nutritional value (dietary energy, protein, fatty acids, fibers, dietary minerals and vitamins composition. Some edible insects species, which contains a relatively large amount of fat, can have a potential to be a „good" (interesting, new source of minor lipophilic compounds such as sterols (cholesterol and phytosterols and tocopherols in our diet. For this reason, the objective of this work was to characterize the sterols and tocopherols composition of fat from larvae of edible insect Zophobas morio L. and Tenebrio mollitor L. Cholesterol and three phytosterols (campesterol, stigmasterol and β-sitosterol were reliably identified and quantified after hot saponification and derivatization by GC-MS. Other steroid compounds, including 5,6-trans-cholecalciferol were identified only according to the NIST library. Cholesterol was the predominant sterol in all analysed samples. Both types of larvae also contained high amount of phytosterols. Different region of origin had a no significant impact on sterols composition, while the effect of beetle genus was crucial. Tocopherols were analysed by reverse phase HPLC coupled with amperometric detection. Tocopherols content in mealworm larvae was lower than content in edible oils, but important from the nutritional point of view. Change of tocopherols composition was not observed during the storage under different conditions. Larvae of edible insect can be a potential good dietary source of cholesterol, but also vitamin D3 isomers, phytosterols and tocopherols.

  4. Particle-hole intruder levels in 67Cu, collectivity, monopole shifts, and the hockey-stick behaviour of ell - 1/2 5/2- levels in neutron-rich odd-mass Cu nuclei

    Science.gov (United States)

    Walters, W. B.; Chiara, C. J.

    2011-01-01

    A new sequence of gamma rays with energies of 572, 499, 585, and 674 keV has been identified in 67Cu populating the 7/2- level at 2362 keV. Owing to the strong population of the 2362-keV level via an ell = 3 proton pickup reaction, that level is assigned to be an f7/2-1 2-particle-1-hole "intruder" proton configuration, and the new levels are found to form a sequence consistent with intruder sequences in the adjacent odd-mass Cu isotopes and in the odd-mass Sb isotopes. The changing position of the intruder sequence in the odd-mass Cu isotopes is discussed and related to the onset of collectivity associated with the presence of g9/2 neutrons beyond N = 40. The increase in collectivity is also discussed for a number of isotonic and isotopic chains as more protons or neutrons, respectively, are added beyond an oscillator shell boundary. For most of these systems, the ell -1/2 levels show a systematic "hockey-stick-like" behaviour with a sharp decrease in energy with the addition of the first protons or neutrons, owing to both the added collectivity and the tensor interaction, and then a lower slope when collectivity changes are diminished and only the tensor interaction is influencing the changes in level positions.

    While major mergers and their tidal debris are well studied, they are less common than minor mergers and likely played a role in forming most large galaxies, including the Milky Way. Tidal debris regions have large amounts of neutral gas but a lower gas density and may have higher turbulence.Star formation tracers such as young star cluster populations and Halpha, CO, and CII emission were studied to determine the different factors that may influence star formation in tidal debris. These tracers were compared to the reservoirs of gas available for star formation to estimate the star formation efficiency (SFE). The SFR of tidal debris can reach up to 50% of the total star formation in the system. The SFE of tidal tails in minor mergers can range over orders of magnitude on both local and global scales. From the tidal debris environments in this study, this variance appears to stem from the formation conditions of the debris. A large survey with TMT as well as the continuing programs of ALMA and the EVLA can provide a larger sample of environments to study the threshold for star formation and can inform star formation models, particularly at low densities.

  8. Advanced Recycling Reactor with Minor Actinide Fuel

    International Nuclear Information System (INIS)

    The Advanced Recycling Reactor (ARR) with minor actinide fuel has been studied. This paper presents the pre-conceptual design of the ARR proposed by the International Nuclear Recycling Alliance (INRA) for FOA study sponsored by DOE of the United States of America (U.S.). Although the basic reactor concept is technically mature, it is not suitable for commercial use due to the need to reduce capital costs. As a result of INRA's extensive experience, it is anticipated that a non-commercial ARR1 will be viable and meet U.S. requirements by 2025. Commercial Advanced Recycling Reactor (ARR) operations are expected to be feasible in competition with LWRs by 2050, based on construction of ARR2 in 2035. The ARR based on the Japan Sodium-cooled Fast Reactor (JSFR) is a loop-typed sodium cooled reactor with MOX fuel that is selected because of much experience of SFRs in the world. Major features of key technology enhancements incorporated into the ARR are the following: Decay heat can be removed by natural circulation to improve safety. The primary cooling system consists of two-loop system and the integrated IHX/Pump to improve economics. The steam generator with the straight double-walled tube is used to improve reliability. The reactor core of the ARR1 is 70 cm high and the volume fraction of fuel is 31.6%. The conversion ratio of fissile is set up less than 0.65 and the amount of burned TRU is 45-51 kg/TWeh. According to survey of more effective TRU burning core, the oxide fuel core containing high TRU (MA 15%, Pu 35% average) with moderate pins of 12% arranged driver fuel assemblies can decrease TRU conversion ratio to 0.33 and improve TRU burning capability to 67 kg/TWeh. The moderator can enhance TRU burning, while increasing the Doppler effect and reducing the positive sodium void effect. High TRU fraction promotes TRU burning by curbing plutonium production. High Am fraction and Am blanket promote Am transmutation. The ARR1 consists of a reactor building (including

    The links of minority stressors (workplace discrimination, expectations of stigma, internalized heterosexism, and identity management strategies) with psychological distress and job satisfaction were examined in a sample of 326 sexual minority employees. Drawing from minority stress theory and the literature on the vocational experiences of sexual minority people, patterns of mediation and moderation were tested. Minority stressors were associated with greater distress and lower job satisfaction. A mediation model was supported in which the links of discrimination and internalized heterosexism with psychological distress were mediated by a concealment-focused identity management strategy (i.e., avoiding), and the links of discrimination, expectations of stigma, and internalized heterosexism with job satisfaction were mediated by a disclosure-focused identity management strategy (i.e., integrating). Tests of moderation indicated that for sexual minority women (but not men), the positive association of discrimination with distress was stronger at higher levels of internalized heterosexism than at lower levels. In addition, lower levels of internalized heterosexism and concealment strategies (i.e., counterfeiting and avoiding) and higher levels of a disclosure strategy (i.e., integrating) were associated with higher job satisfaction in the context of low discrimination, but this buffering effect disappeared as level of discrimination increased. The implications of these findings for minority stress research are discussed, and clinical recommendations are made.

    International Nuclear Information System (INIS)

    Our first aim was to optimize the power fraction absorbed by minority ions. This led to the concept of optimized antenna which is adapted to transfer power from the source to the particle (minority ions) sink. Such an antenna can be closely approximated by a quadrupole antenna. But due to the coupling between the species, and the nature of the power transfer to particles, ions and electrons, the more complete condition of equating the power delivered by the antenna to the absorption by minority ions and by electrons was discussed.

  16. Tidal Tales of Minor Mergers: Star Formation in the Tidal Tails of Minor Mergers

    Science.gov (United States)

    Knierman, Karen A.

    This work examines star formation in the debris associated with collisions of dwarf and spiral galaxies. While the spectacular displays of major mergers are famous (e.g., NGC 4038/9, "The Antennae''), equal mass galaxy mergers are relatively rare compared to minor mergers (mass ratio <0.3) Minor mergers are less energetic than major mergers, but more common in the observable universe and, thus, likely played a pivotal role in the formation of most large galaxies. Centers of mergers host vigorous star formation from high gas density and turbulence and are surveyed over cosmological distances. However, the tidal debris resulting from these mergers have not been well studied. Such regions have large reservoirs of gaseous material that can be used as fuel for subsequent star formation but also have lower gas density. Tracers of star formation at the local and global scale have been examined for three tidal tails in two minor merger systems. These tracers include young star cluster populations, H-alpha, and [CII] emission. The rate of apparent star formation derived from these tracers is compared to the gas available to estimate the star formation efficiency (SFE). The Western tail of NGC 2782 formed isolated star clusters while massive star cluster complexes are found in the UGC 10214 ("The Tadpole'') and Eastern tail of NGC 2782. Due to the lack of both observable CO and [CII] emission, the observed star formation in the Western tail of NGC 2782 may have a low carbon abundance and represent only the first round of local star formation. While the Western tail has a normal SFE, the Eastern tail in the same galaxy has an low observed SFE. In contrast, the Tadpole tidal tail has a high observed star formation rate and a corresponding high SFE. The low SFE observed in the Eastern tail of NGC 2782 may be due to its origin as a splash region where localized gas heating is important. However, the other tails may be tidally formed regions where gravitational compression likely

    2012-01-01

    Objective To examine how knowledge about the Texas top 10% law influences college enrollment decisions of high achieving students minority and nonminority students. Data and Methods Using a representative survey of graduates from Texas public high schools in 2002, we compare self-reported and transcript-verified class rank and estimate probit models to assess the likelihood that top-ranked minority students know about the law. Results Family socioeconomic status largely explains why highly ranked black and Hispanic students know less about the top 10% law than comparable whites, but parents’ lack of fluency in English is a significant information barrier for college-bound, top 10% Hispanic students from predominantly minority high schools. Nearly one-fifth of college-oriented black and Hispanic top 10% seniors who did not know about the law failed to enroll anywhere. Conclusion Inadequate information about the top 10% law undermines enrollment of talented minorities in higher education. PMID:23293398

    Research examining how sexual minorities characterize love within same-sex relationships is scarce. In this study, we examined the validity of Sternberg's Triangular Theory of Love in a sample of sexual minority male youth (N = 447). To test the adequacy of the theory for our population, we examined the psychometric properties of the Triadic Love Scale (TLS) and tested whether the three underlying constructs of the theory (Intimacy, Passion, and Commitment) emerged when participants were asked to consider their ideal relationship with another man. Using confirmatory factor analysis (CFA), we found support for the three-factor solution to characterize sexual minority male youths' ideal romantic relationship, after minimizing item cross-loadings and adapting the content of the Passion subscale. We discuss the implications of our findings regarding the measurement of the TLS among sexual minority male youth and propose ways to enhance its measurement in future research. PMID:21709758

    2016-01-01

    The current generation of D-Wave quantum annealing processor is designed to minimize the energy of an Ising spin configuration whose pairwise interactions lie on the edges of a Chimera graph C_{M,N,L}. In order to solve an Ising spin problem with arbitrary pairwise interaction structure, the corresponding graph must be minor-embedded into a Chimera graph. We define a combinatorial class of native clique minors in Chimera graphs with vertex images of uniform, near minimal size and provide a polynomial-time algorithm that finds a maximum native clique minor in a given induced subgraph of a Chimera graph. These minors allow improvement over recent work and have immediate practical applications in the field of quantum annealing.

    In this study, I used ethnographic methods to examine suicidality and nonsuicidal self-harm among gay, lesbian, bisexual, and transgender persons in Japan. Participants (N = 84) indicated that suicidality and self-harm are serious problems among sexual minorities and tend to be driven by (a) a homophobic/transphobic environment and the negative consequences of sexual minorities either disclosing their true selves or remaining hidden and silent within such an environment; (b) various antecedents to poor mental health; and (c) factors not directly related to being a sexual minority, particularly unemployment and debt in the context of a protracted national economic decline in Japan prior to the study period of 2003--2004. Participants also perceived a potentially higher risk for suicidality and self-harm among sexual minority adolescents and persons in their early 20s; those who work in the entertainment, bar, or sex industries; and survivors of violence perpetrated by intimate partners or family members.

  10. In the Margins: Minority Education in Central Asia

    Directory of Open Access Journals (Sweden)

    Kazimzade E.

    2011-03-01

    Full Text Available This article reviews separate education for ethnic minorities in two Central Asian countries - Tajikistan and Kazakhstan. Students and teachers from minority and majority groups in each country were asked 1 whether separate schools for minorities persevered minority cultural identity and 2 whether such schools undercut equal educational opportunities for minority students. Analysis indicates that in some political, social and educational contexts separation puts minority youth at a disadvantage, which in turn keeps them from fully integrating into society. Redressing this situation requires a commitment to guaranteeing rights and full citizenship for minorities. This paper explores how separate school systems deepen ethnic and political divisions in society rather than promote equality and equity. It begins with a number of questions. How much emphasis do current education reform initiatives put on equity and equality in minority schools? What is the balance between economic and civic imperatives in the education policy process in the two countries? What are the main features of post-transition phase in education and how it affects separate education? As mentioned in the foreword of this issue, data analyzed for this study was collected under the auspices of the “Divided Education, Divided Citizens” project, which was conducted in seven post-socialist countries. This article concentrates on separate schooling for different ethnic and linguistic groups and issues related to the civil enculturation of minorities in two Central Asian countries, Tajikistan and Kazakhstan. Study participants from minority and majority language-track schools in each country were asked to observe whether separate schools for minority ethnicities served to preserve culture or instead undercut equal educational opportunity. Pervious investigations have found that education plays a fundamental role in shaping individuals’ perceptions of their own ethnicity

In mice given infective eggs, orally, hatch of the third stage larvae was noted in the gut wall, with migration to liver, lungs, skeletal musculature and subcutaneous tissue becoming, soon after, encysted. In cats infected with skinned carcasses of mice (60 to 235 days of infection it was observed: hatch of third stage larvae from the nodules (cysts in the stomach, migration through the oesophagus, pharynx, trachea, related tissues (rhino-oropharynx, and cervical lymphonodes developing to the mature stage in any of these sites on days 9-20 post inoculation (P.I.. There was no parasite development up to the mature stage in cats inoculated orally with infective eggs, which indicates that the life cycle of this parasite includes an obligatory intermediate host. In one of the cats (fed carcass of infected mice necropsied on day 43 P.I., it was observed the occurence of the self-infective cycle of L. minor in the lung tissues and in the cervical region which was characterized by the finding of eggs in different stages of development, third stage larvae and mature worms. It's believed that some component of the carnivorae gastrointestinal tracts may preclude the development of third stage larvae from L. minor eggs what explains the interruption of the life cycle in animals fed infective eggs. It's also pointed out the role of the intermediate host in the first stages of the life cycle of this helminth.A partir de material colhido de lesões humanas estudou-se o ciclo evolutivo de Lagochilascaris minor empregando-se o modelo experimental: roedores (camundongos, hamster e carnívoros (gatos, cão.

    2011-01-01

    Background and objective: Expectations and beliefs are important predictors of outcome following minor head injury. In this paper, the primary purpose is to develop a simple symptom expectation questionnaire for minor head injury for use in future research studies. Methods: An existing database of 179 injury-naive subjects who completed a 56-item checklist of expected symptoms for minor head injury was analyzed to determine which items could correctly identify an a priori case definition of an expecter (a subject who expected at least one of these symptoms would remain chronic following minor head injury). A total of six of the 56 items were found to be discriminatory, and these were tested in additional subject groups against the original questionnaire. Results: From the original database of 179 subjects completing a 56-item symptom expectation checklist, 135 expected that at least one of the 56 symptoms would be chronic following minor head injury. The 135 expecters, however, all chose at least one of six items: headache, anxious or worried, depressed, difficulty concentrating, dizziness, and neck pain. Using these six items, in two new groups of subjects, all those who endorsed one of the 56 symptoms as likely to be chronic following minor head injury (expecters) could also be identified on the 6-item checklist. Conclusions: A shortened (6-item) symptom expectation checklist of commonly reported symptoms following minor head injury (headache, anxious or worried, depressed, difficulty concentrating, dizziness, and neck pain) correctly identifies subjects who expect that at least one symptom will be chronic following minor head injury (i.e., an expecter).

  6. THE CHARACTERISTICS AND MAIN PROBLEMS OF MINORITY REGIONS IN CHINA

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    China is a country that has a large number of minorities, who live in specific regions which are mainly located in central and west China. These regions are abundant in natural resources, which are potential advantages and also an important basis for economic development in these regions. They are of general importance for China in strategic and ecological terms. They will not only affect the environment for survival of the minority regions but also affect the sustain able development of the eastern and central parts of China and even the survival and development of the Chinese nation as a wbole. Minorities live in relatively compact communities, among the 55 minorities, 35 of them were highly compact minorities, with a compact level of more than 90%. Here the development in infrastructure as well as social and econonic development (e. g. export-oriented economy) has been and is still slow, regional poverty are most concentrated. The economic structures in minority areas are still in the low stage, which have resulted in underdevelopment in these regions.

    2012-12-01

    A pheromone-based system to locate and monitor Planococcus minor (Maskell), a pest of over 250 plants including citrus, grape, and cacao, was tested. The difficulty in distinguishing P. minor from the citrus mealybug, P. citri, makes finding and evaluating the impact of the pest challenging. Studies conducted in Puerto Rico determined that synthetic P. minor pheromone lures preaged 120 d in the field caught similar number of males as lures not aged (fresh). Molecular analysis of trapped mealybug males using mitochondrial cytochrome oxidase-1, the internal transcriber space two locus, and 28S-D2 gene showed the pheromone traps to be species specific. Traps baited with P. minor pheromone were used to monitor the pest in south Florida and to locate potential infestations. P. minor males were found at all locations studied in South Florida and were present in low numbers (1.03 +/- 0.69 mean +/- SE/trap/14 d). Over 14,000 terminals, fruit, and flowers were visually inspected over a 6 mo period of peak trap catches before the first adult P. minor female was found. The synthetic pheromone lures proved to be an effective tool to locate and monitor this pest new to the continental United States.

A matter which concerns investors and especially foreign ones is the protection of minority shareholders. This paper discusses the instruments of protection of minority shareholders bringing the novelties of the newly introduced laws because of the unclear regime under the repealed law using the analytical and comparative method. Few rights which were known by the former Albanian company law were usually compromised, but under the law in force, minorities are much more protected.Does the new law strengthen the position of such category of shareholders? What are the rights of minority shareholders conferred by the law? These and other questions will be addressed herein.

  9. Contested minorities – the case of Upper Silesia

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Upper Silesia in terms of ethnicity is a typical example of a historical region in Europe, but in fact, one of the few exceptions in contemporary Poland, where its mixed ethnic and religious structures have at least partly survived until today. While their existence had been denied by Nazi Germany (1933-1945 as well as by the Polish People's Republic (1945-1989, the emancipation of the German and Silesian minorities after the democratic changes of 1989 have evoked strong emotions in the ethnically almost uniform country. Nonetheless, the recent situation of minorities has improved as never before. Minority organisations has been officially recognized and German finally has become the second language in some municipalities of Upper Silesia, but the largest ethnic group in the whole country, the Silesians, have still experienced no formal recognition as a national minority. This article deals with the demographic aspects of the ethnic groups in Upper Silesia since the 19th century until recent times. The census results concerning the ethnic minorities or languages in Upper Silesia have been contested since the first records of that kind have been taken. The outcomes of the both last censuses of 2002 and 2011 concerning the minority question reflected for the first time a much more realistic picture of the status quo. Furthermore, they showed that the idea of Silesian identification found an unexpected high number of supporters. This fact indicates an emerging meaning of regional identification amid significant changes of cultural values in Polish society.

    Full Text Available In the ethnically fragmented countries, it is almost taken for granted that the EU has a positive impact on minority rights protection. Those states made important legislative changes improving the protection level granted to minorities, which without the EU’s conditionality would have been impossible. In response to the perspective of membership and the pressure accompanying it, they have adopted legislative changes in the course of the accession process. However, such domestic changes can be misleading in two aspects. Firstly, formal changes may not be followed by behavioral ones and usually a gap between legislative changes and their implementation can be observed. While for the former only rationally induced factors would be sufficient enough to instigate change, for the latter, a certain level of change in attitudes is also necessary. Secondly, the EU’s impact cannot be confined to the formal changes. It has an impact on the emergence of new attitudes, identities, and beliefs. These socialization-based changes might not be parallel with formal changes, which in time might lead to opposite behavioral shifts.The main argument of this paper is that Europeanization of minority rights in Turkey goes hand in hand with these two nexus. On the one hand, there is a top- to-bottom policy-Europeanization with respect to minority rights without parallel internalization at the governmental level. This means policy changes are not necessarily internalized in a way culminating in normative and behavioral shifts. There can be modest changes; however, the “core” of the minority protection system remains untouched at the institutional and legislative level. However, in general sense, the direction of domestic change is positive compared to the previous status quo. On the other hand, new patterns of recognition-exclusion nexus have emerged due to the EU’s involvement, underlying antagonism between majority-minority groups. Policy changes and their

    Full Text Available This study examines the disproportionately poor academic performance of the Hmong among the minorities in Vietnam by using Ogbu’s cultural ecological theory (Ogbu, 2003. Societal and school factors have been assumed by many policy makers and scholars to affect minorities’ equally, but the paper argues that may not be the case when minority status is taken into account. “Community forces”are pointed to as the putative cause of the Hmong’s differential academic performance. “Community forces” of each ethnic group are related to their status as a minority group,which orients their interpretations and responses to schooling. In this paper, the minority status of the Hmong is explained through their group development history, settlement patterns, livelihoods and economic adaptive strategies and political participation through a review of the scholarly literature on the Hmong. Additionally, field research was conducted in Vietnam using a grounded theory approach to ethnography to understand how minority status influences community forces, and in turn, how these community forces affect the schooling of Hmong students.

    Rotation curves and velocity dispersion profiles have been determined for the major and the minor axes of 22 elliptical galaxies. Rotation was detected in all but one galaxy, even though the sample was biased toward round ellipticals. Minor axis rotation larger than major axis rotation was measured in two galaxies, NGC 4406 and NGC 7507. Roughly 10 percent of ellipticals may show large minor axis velocities relative to those on the major axis. A simple model is used to derive a rotational axis from the observed minor and major axis velocities to a typical accuracy of 6 deg. The rotational and photometric minor axes aligned to better than 10 deg for 60 percent of the sample, implying that the direction of the angular momentum is related to the orientation of the figure of the galaxy. IC 1459 has a kinematically distinct core with its angular momentum opposite to the angular momentum of the outer parts, and NGC 4406 has a core with its angular momentum perpendicular to that of the outer parts.

    The present study investigates the ability of two genus of duckweed (Lemna minor and Spirodela polyrhiza) to phytoremediate cadmium from aqueous solution. Duckweed was exposed to six different cadmium concentrations, such as, 0.5,1.0,1.5, 2.0, 2.5, and 3.0 mg/L and the experiment was continued for 22 days. Water samples were collected periodically for estimation of residual cadmium content in aqueous solution. At the end of treatment period plant samples were collected and accumulated cadmium content was measured. Cadmium toxicity was observed through relative growth factor and changes in chlorophyll content Experimental results showed that Lemna minor and Spirodela polyrhiza were capable of removing 42-78% and 52-75% cadmium from media depending upon initial cadmium concentrations. Cadmium was removed following pseudo second order kinetic model Maximum cadmium accumulation in Lemna minor was 4734.56 mg/kg at 2 mg/L initial cadmium concentration and 7711.00 mg/kg in Spirodela polyrhiza at 3 mg/L initial cadmium concentration at the end of treatment period. Conversely in both cases maximum bioconcentration factor obtained at lowest initial cadmium concentrations, i.e., 0.5 mg/L, were 3295.61 and 4752.00 for Lemna minor and Spirodela polyrhiza respectively. The present study revealed that both Lemna minor and Spirodela polyrhiza was potential cadmium accumulator. PMID:24933906

  17. The Limits of EU Conditionality: Minority Rights in Slovakia

    Full Text Available This article discusses the impact of EU conditionality on minority rights in Slovakia from a legal point of view. The study of the Slovak case demonstrates the visibility and degree of the EU's contribution to the stabilization of the rule of law, democracy and the creation of legislation on the protection of ethnic minorities in one of the most complex of transition states. At the same time, the article argues that despite the propagation of some ambitious laws in Slovakia, the EU's contribution has had a limited effect on shaping the attitude of Slovak society towards minority rights. Both the formulation of 'recommendations' and criticisms by the EU and the 'responses' emanating from Slovakia, in terms of norms and policy, are examined, leading the author to conclude that the role of the EU in monitoring Slovakia's performance in protecting minority rights has suffered both from an unclear strategy and structural deficiencies, which have subsequently become embedded in Slovakia's domestic legal profile on minority issues.

  18. Empowering minority students: An analysis of the bilingual education debate

    Full Text Available This paper argues that the nature of the bilingual education debate, represents a drama of societal self-definition. On one hand the commitment to preserve traditional power structures, and on the other, the desire to live up to theideals upon which the U.S.was founded. The latter implies the creation of a society where equality, freedom and justice represent more than just empty rhetoric. In order to build his case, the author examines the historical context of minority education in the U.S. and the surface text of the arguments both for and against the effectiveness of bilingual education. He concludes that the fundamental causes of minority students' school failure are rooted in socio historical processes of minority group disempowerment. The ways are outlined in which schools have traditionally reflected the societal power structure and rationalized the education disablement of minority students. An invention framework designed to reverse this pattern and prevent minority student academic failure is proposed. However, the author cautions that the implementation of empowerment pedagogy is unlikely to be facilitated by the dominant group because, almost by definition. empowerment pedagogy requires educators as individuals and schools as institutions to challenge the institutionalized racism that still persists in many aspects of society.

Conclusion: The counseling program “Safe and effective use of medicines” was successfully adapted to unemployed ethnic minority patients, and tested in a new collaboration between job centers and community pharmacies. The counseling program resulted in statistically significant improvements......Background: From studies, we know how ethnic minorities and people with reduced work ability often suffer from health problems, thus being socially disadvantaged. The municipal job centers are confronted with numerous problems related to medicine use and they lack relevant means of referral. Thus......, there was a need to adapt a previously developed and validated medicine-based intervention “safe and effective use of medicines” to this vulnerable group of unemployed ethnic minority patients. Methods: The objective of this before-after study was to improve medicines adherence, health status and work ability...

  20. Factors affecting minority population proximity to hazardous facilities

    Disproportionate exposure of minority groups to environmental hazards has been attributed to ``environmental racism`` by some authors, without systematic investigation of the factors underlying this exposure pattern. This study examines regional differences in the proximity of African-Americans, Hispanics, Asians, and non-Hispanic Whites to a broad range of facility types and explores the effects of urban and income factors. A statistically significant inverse relationship is found between the percentage of non-Hispanic Whites and virtually all facility categories in all regions. Except for Hispanics in the South, all such associations for minority groups show a direct relationship, though some are nonsignificant. The geographic concentration of facilities is more closely tied to urbanization than to economic factors. Controlling for both urban and economic factors, minority population concentration is still a significant explanatory variable for some facility types in some regions. This finding is most consistent for African-Americans.
