    Phillips, Tom L. [Department of Plant Biology, School of Integrative Biology, University of Illinois, Urbana, IL 61801 (United States)

    2007-01-02

    An Ohioan by birth, June 4, 1916, in Findlay, Hancock County, Aureal T. Cross grew up an Iowan on a dairy farm near Waterloo at Castle Hill. He was the second of five children of Congregational Minister Raymond W. and Mrs. Myra Jane Coon Cross. Aureal's grade school education was mostly in a one-room school at Castle Hill, then to East Waterloo, junior high and high school, where music was as important as farm work before and after classes. On a history and music scholarship at Coe College in Cedar Rapids, Aureal was drawn to L. R. Wilson's physical geology course and the summer reconnaissance trips. Graduating from Coe College in 1939 with an honors thesis on pollen analysis, Aureal completed his Masters in 1941 and a PhD thesis in 1943 at the University of Cincinnati with J. H. Hoskins on Pennsylvanian age plants from coal-balls. During 1942-1946 he taught premedical U.S. Navy students at the University of Notre Dame with a 1943-1944 leave as a National Research Council Fellow. Aureal and Christina Aleen Teyssier met during 1943 in Pittsburgh and married in 1945. Aureal replaced K. E. Caster, his paleontology mentor, for three and one half years (1946-1949) in the Geology Department at Cincinnati, and did field mapping for the Ohio Geological Survey during the summers. Cross established (1949-1957) productive graduate training and research programs in the West Virginia University Geology Department and the West Virginia Geologic and Economic Survey where he had dual appointments. His move (1957-1961) to Exploration Geology, at Amoco's Pan American Petroleum Corporation Research Center in Tulsa, Oklahoma, permitted him to develop and supervise a major palynological research group. The return to academia (1961) at Michigan State University in East Lansing resulted in one of the most comprehensive graduate training programs in paleobotany, palynology, biostratigraphy and paleoecology in North America. Although Aureal Cross officially retired in 1986

    2010-01-01

    Recently a novel submaximal test, known as the Lamberts and Lambert submaximal cycle test (LSCT), has been developed with the purpose of monitoring and predicting changes in cycling performance. Although this test has been shown to be reliable and able to predict cycling performance, it is not known whether it can measure changes in training status. Therefore, the aim of this study was to determine whether the LSCT is able to track changes in performance parameters, and objective and subjective markers of well-being. A world class cyclo-cross athlete (31 years) volunteered to participate in a 10-week observational study. Before and after the study, a peak power output (PPO) test with respiratory gas analysis (VO(2max)) and a 40-km time trial (40-km TT) test were performed. Training data were recorded in a training logbook with a daily assessment of well-being, while a weekly LSCT was performed. After the training period all performance parameters had improved by a meaningful amount (PPO +5.2%; 40-km TT time -2.5%; VO(2max) +1.4%). Increased training loads during weeks 2 and 6 and the subsequent training-induced fatigue was reflected in the increased well-being scores. Changes during the LSCT were most clearly notable in (1) increased power during the first minute of third stage, (2) increased rating of perceived exertion during second and third stages, and (3) a faster heart rate recovery after the third stage. In conclusion, these data suggest that the LSCT is able to track changes in training status and detect the consequences of sharp increases in training loads which seem to be associated with accumulating fatigue.

    A main problem in maintenance in general, and in power plants and related equipment in particular, is the lack of a practical, consistent, and adaptive performance measure that provides a focused feedback and integrates preventive and corrective modes of maintenance. The presentation defines concepts of world class and benchmarking. Desirable features in an appropriate performance measure are identified. It then, demonstrates current practices in maintenance and criticises their shortcomings. An alternative model is presented through a case study. The model monitors performance from a general view, and then offers a focused analysis. The main conclusion is that the proposed model offers an adaptive and a dynamic framework, and hence production and maintenance are integrated in a `real time` environment. The system is also flexible in working with any other criteria whether they are of a quantitative or a qualitative nature. (orig.) 16 refs.

    Full Text Available The dominance of Jamaican sprinters in international meets remains largely unexplained. Proposed explanations include demographics and favorable physiological characteristics. The aim of this study was to analyze the demographic characteristics of world class Jamaican sprinters. Questionnaires administered to 120 members of the Jamaican national team and 125 controls elicited information on place of birth, language, ethnicity, and distance and method of travel to school. Athletes were divided into three groups based on athletic disciplines: sprint (s: 100–400 m; n=80, jump and throw (j/t: jump and throw; n=25 and, middle distance (md: 800–3000 m; n=15. Frequency differences between groups were assessed using chi-square tests. Regional or county distribution of sprint differed from that of middle distance (P<0.001 but not from that of jump and throw athletes (P=0.24 and that of controls (P=0.59. Sprint athletes predominately originated from the Surrey county (s = 46%, j/t = 37%, md = 17, C = 53%, whilst middle distance athletes exhibited excess from the Middlesex county (md = 60%. The language distribution of all groups showed uniformity with a predominance of English. A higher proportion of middle distance and jump and throw athletes walked to school (md = 80%, j/t = 52%, s = 10%, and C = 12% and travelled greater distances to school. In conclusion, Jamaica’s success in sprinting may be related to environmental and social factors.

    Bamford, James; Ernst, David; Fubini, David G

    2004-02-01

    More than 5,000 joint ventures, and many more contractual alliances, have been launched worldwide in the past five years. Companies are realizing that JVs and alliances can be lucrative vehicles for developing new products, moving into new markets, and increasing revenues. The problem is, the success rate for JVs and alliances is on a par with that for mergers and acquisitions--which is to say not very good. The authors, all McKinsey consultants, argue that JV success remains elusive for most companies because they don't pay enough attention to launch planning and execution. Most companies are highly disciplined about integrating the companies they target through M&A, but they rarely commit sufficient resources to launching similarly sized joint ventures or alliances. As a result, the parent companies experience strategic conflicts, governance gridlock, and missed operational synergies. Often, they walk away from the deal. The launch phase begins with the parent companies' signing of a memorandum of understanding and continues through the first 100 days of the JV or alliance's operation. During this period, it's critical for the parents to convene a team dedicated to exposing inherent tensions early. Specifically, the launch team must tackle four basic challenges. First, build and maintain strategic alignment across the separate corporate entities, each of which has its own goals, market pressures, and shareholders. Second, create a shared governance system for the two parent companies. Third, manage the economic interdependencies between the corporate parents and the JV. And fourth, build a cohesive, high-performing organization (the JV or alliance)--not a simple task, since most managers come from, will want to return to, and may even hold simultaneous positions in the parent companies. Using real-world examples, the authors offer their suggestions for meeting these challenges.

    2007-08-01

    World currency network constitutes one of the most complex structures that is associated with the contemporary civilization. On a way towards quantifying its characteristics we study the cross correlations in changes of the daily foreign exchange rates within the basket of 60 currencies in the period December 1998 May 2005. Such a dynamics turns out to predominantly involve one outstanding eigenvalue of the correlation matrix. The magnitude of this eigenvalue depends however crucially on which currency is used as a base currency for the remaining ones. Most prominent it looks from the perspective of a peripheral currency. This largest eigenvalue is seen to systematically decrease and thus the structure of correlations becomes more heterogeneous, when more significant currencies are used as reference. An extreme case in this later respect is the USD in the period considered. Besides providing further insight into subtle nature of complexity, these observations point to a formal procedure that in general can be used for practical purposes of measuring the relative currencies significance on various time horizons.

    2009-09-01

    In this study, we examined the role of confidence in relation to the cognitive, affective, and behavioural responses it elicits, and identified the factors responsible for debilitating confidence within the organizational subculture of world-class sport. Using Vealey's (2001) integrative model of sport confidence as a broad conceptual base, 14 athletes (7 males, 7 females) were interviewed in response to the research aims. Analysis indicated that high sport confidence facilitated performance through its positive effect on athletes' thoughts, feelings, and behaviours. However, the athletes participating in this study were susceptible to factors that served to debilitate their confidence. These factors appeared to be associated with the sources from which they derived their confidence and influenced to some extent by gender. Thus, the focus of interventions designed to enhance sport confidence must reflect the individual needs of the athlete, and might involve identifying an athlete's sources and types of confidence, and ensuring that these are intact during competition preparation phases.

    Goodspeed, Scott W

    2006-01-01

    This article describes the emerging trend of using metrics in rural hospitals to achieve world-class performance. This trend is a response to the fact that rural hospitals have small patient volumes yet must maintain a profit margin in order to fulfill their mission to the community. The conceptual idea for this article is based largely on Robert Kaplan and David Norton's Balanced Scorecard articles in the Harvard Business Review. The ideas also come from the experiences of the 60-plus rural hospitals that are using the Balanced Scorecard and their implementation of metrics to influence performance and behavior. It is indeed possible for rural hospitals to meet and exceed the unique needs of patients and physicians (customers), to achieve healthy profit margins, and to be the rural hospital of choice that employees are proud to work for.

    Stress fracture presents a difficult problem in the high performance, world-class athlete. Competitive demands provide little tolerance for, or agreement with, prolonged periods of rest which are the first line of conservative treatment methods. The use of a specifically programmed, pulsed, low-intensity ultrasound device to shorten the time of healing was investigated in a well-known gymnast with an Olympic deadline. Prior animal, in vitro, and clinical studies had established the safety and effectiveness of this device in fractures. The location of the stress injury was in the mid-tibia which is considered to present the greatest challenge to an early healing result. The low-intensity ultrasound device was prescribed for daily use at home. At 3 wk after the start of low-intensity ultrasound, the stress fracture responded well and the patient was allowed use of tumble track, trampoline, and to do some weight-bearing activities, such as jumping in the pool and loading-type activities. At 4.5 wk, the patient progressed to full workout activities and participated in a trial meet for the Olympics. At 6 wk, the patient's participation in the women's gymnastic team event was a factor in the United States receiving a gold medal.

  16. Strategic aspects of reaction time in world-class sprinters.

    Collet, C

    1999-02-01

    Simple reaction time (RT) is defined as the time duration following the initiation of a stimulus and the resultant first observable response. For sprinters, RT to a start should be especially important, as this may determine the outcome of the race. The aim of this study was to investigate whether sprinters (from 100 to 400 m) try to anticipate the starter's shot within the false start limit (100 msec. after the shot). Subjects were male sprinters who have reached the final of a sprint event in World Championships or Olympic Games. Analysis indicated that RT to the starting shot plays a role in the eight finalists' strategy throughout an event (requiring a total of four sprints). Four characteristics of the strategic aspects of RT were found: (i) Increased mean RT from short dashes to longer sprints (from 60 m indoor, to 100 m, 200 m, and 400 m); (ii) RT values increase as a function of race length, i.e., the RT of the first sprinter in a 4 x 100-m relay is no different from that of a 400-m sprinter; conversely, RT of the first relay sprinter in a 4 x 400-m, i.e., a 1600-m race, is significantly different from RT in a 400-m race; (iii) RT decreases from the heats to the final for the eight finalists; (iv) Decreased RT is not observable in less experienced sprinters through the qualifying rounds (junior 18- or 19-yr.-old sprinters, taking part in their own World Championships). RT must be considered a skill dependent upon experience and learning and is associated with race length. The shorter the race, the more important the RT is for the final performance (both time and place), so sprinters try to decrease RT in the shorter dashes (60 m and 100 m). In the longer sprint races (4 x 400-m relay) they are content to respond to the shot. Intermediate distance races elicit intermediate values of RT. Such behavior could be explained by the importance of RT throughout the factors which influence sprint performance and by reference to allocation of concentration resources

  17. Programs=data=first-class citizens in a computational world.

    Jones, Neil D; Simonsen, Jakob Grue

    2012-07-28

    From a programming perspective, Alan Turing's epochal 1936 paper on computable functions introduced several new concepts, including what is today known as self-interpreters and programs as data, and invented a great many now-common programming techniques. We begin by reviewing Turing's contribution from a programming perspective; and then systematize and mention some of the many ways that later developments in models of computation (MOCs) have interacted with computability theory and programming language research. Next, we describe the 'blob' MOC: a recent stored-program computational model without pointers. In the blob model, programs are truly first-class citizens, capable of being automatically compiled, or interpreted, or executed directly. Further, the blob model appears closer to being physically realizable than earlier computation models. In part, this is due to strong finiteness owing to early binding in the program; and a strong adjacency property: the active instruction is always adjacent to the piece of data on which it operates. The model is Turing complete in a strong sense: a universal interpretation algorithm exists that is able to run any program in a natural way and without arcane data encodings. Next, some of the best known among the numerous existing MOCs are described, and we develop a list of traits an 'ideal' MOC should possess from our perspective. We make no attempt to consider all models put forth since Turing's 1936 paper, and the selection of models covered concerns only models with discrete, atomic computation steps. The next step is to classify the selected models by qualitative rather than quantitative features. Finally, we describe how the blob model differs from an 'ideal' MOC, and identify some natural next steps to achieve such a model.

    Transformational values and competencies will become critically important by the year 2001 if we are to achieve a health system that fosters community well-being and basic care for all, financed through a combined public-private partnership that is cost effective and uses treatments that unite body, mind and spirit. This article will focus on the use of transformational leadership as a strategy to move health-care organizations beyond traditional values and approaches by building upon the core values of total quality management (TQM). Learning organizations will emerge and finally world-class organizations will evolve, combining the characteristics of total quality and learning organizations, and more. A world-class organization can be described as being the best in its class or better than its competitors in the community, state, nation or world.

    This investigation was designed to analyze the time-trial (STT) in an international cross-country skiing sprint skating competition for (1) overall STT performance and relative contributions of time spent in different sections of terrain, (2) work rate and kinematics on uphill terrain, and (3) relationships to physiological and kinematic parameters while treadmill roller ski skating. Total time and times in nine different sections of terrain by 12 world-class male sprint skiers were determined, along with work rate and kinematics for one specific uphill section. In addition, peak oxygen uptake (VO(2peak)), gross efficiency (GE), peak speed (V(peak)), and kinematics in skating were measured. Times on the last two uphill and two final flat sections were correlated to overall STT performance (r = ~-0.80, P < 0.001). For the selected uphill section, speed was correlated to cycle length (r = -0.75, P < 0.01) and the estimated work rate was approximately 160% of peak aerobic power. VO(2peak), GE, V(peak), and peak cycle length were all correlated to STT performance (r = ~-0.85, P < 0.001). More specifically, VO(2peak) and GE were correlated to the last two uphill and two final flat section times, whereas V(peak) and peak cycle length were correlated to times in all uphill, flat, and curved sections except for the initial section (r = ~-0.80, P < 0.01). Performances on uphill and flat terrain in the latter part were the most significant determinants of overall STT performance. Peak oxygen uptake, efficiency, peak speed, and peak cycle length were strongly correlated to overall STT performance, as well as to performance in different sections of the race.

    There are strong genetic components to cardiorespiratory fitness and its response to exercise training. It would be useful to understand the differences in the genomic profile of highly trained endurance athletes of world class caliber and sedentary controls. An international consortium (GAMES) was established in order to compare elite endurance athletes and ethnicity-matched controls in a case-control study design. Genome-wide association studies were undertaken on two cohorts of elite endurance athletes and controls (GENATHLETE and Japanese endurance runners), from which a panel of 45 promising markers was identified. These markers were tested for replication in seven additional cohorts of endurance athletes and controls: from Australia, Ethiopia, Japan, Kenya, Poland, Russia and Spain. The study is based on a total of 1520 endurance athletes (835 who took part in endurance events in World Championships and/or Olympic Games) and 2760 controls. We hypothesized that world-class athletes are likely to be characterized by an even higher concentration of endurance performance alleles and we performed separate analyses on this subsample. The meta-analysis of all available studies revealed one statistically significant marker (rs558129 at GALNTL6 locus, p = 0.0002), even after correcting for multiple testing. As shown by the low heterogeneity index (I2 = 0), all eight cohorts showed the same direction of association with rs558129, even though p-values varied across the individual studies. In summary, this study did not identify a panel of genomic variants common to these elite endurance athlete groups. Since GAMES was underpowered to identify alleles with small effect sizes, some of the suggestive leads identified should be explored in expanded comparisons of world-class endurance athletes and sedentary controls and in tightly controlled exercise training studies. Such studies have the potential to illuminate the biology not only of world class endurance performance but

    Normal adult aging is associated with impaired muscle contractile function; however, to what extent cross-bridge kinetics are altered in aging muscle is not clear. We used a slacken restretch maneuver on single muscle fiber segments biopsied from the vastus lateralis of young adults (∼23 yr), older nonathlete (NA) adults (∼80 yr), and age-matched world class masters athletes (MA; ∼80 yr) to assess the rate of force redevelopment (ktr) and cross-bridge kinetics. A post hoc analysis was performed, and only the mechanical properties of "slow type" fibers based on unloaded shortening velocity (Vo) measurements are reported. The MA and NA were ∼54 and 43% weaker, respectively, for specific force compared with young. Similarly, when force was normalized to cross-sectional area determined via the fiber shape angularity data, both old groups did not differ, and the MA and NA were ∼43 and 48% weaker, respectively, compared with young (P < 0.05). Vo for both MA and NA old groups was 62 and 46% slower, respectively, compared with young. Both MA and NA adults had approximately two times slower values for ktr compared with young. The slower Vo in both old groups relative to young, coupled with a similarly reduced ktr, suggests impaired cross-bridge kinetics are responsible for impaired single fiber contractile properties with aging. These results challenge the widely accepted resilience of slow type fibers to cellular aging.

    2009-03-01

    The purpose of this study was to determine, based on the time course of the velocity and stride pattern recorded in each 50-m segment of a 400-m competition, whether elite 400-m runners present the same pacing strategy as less successful athletes. Based on video data, 3 different levels of performance were analyzed: world-class, national, and regional levels for both sexes, with each of the 6 groups comprising 5 subjects. The peak velocity was reached by all athletes between the 50- and 100-m marks with mean values of 8.96 and 10.12 m.s for the 5 best women and men, respectively. Peak frequencies were observed in the second and third 50-m segments; peak values were 3.99 +/- 0.13 for the world-class women (WWC) and 4.12 +/- 0.19 for the men (MWC). A stride length of 2.29 +/- 0.04 was observed for the WWC and 2.53 +/- 0.08 for the MWC. The better athletes were able to achieve higher absolute and relative velocities (97.6 +/- 0.5 [MWC] and 96.3 +/- 0.7% [WWC] of their best performance for 200 m) at the 200-m mark compared with the lower-level athletes. Furthermore, the fatigue index was calculated as 22.99, 14.43, and 13.91% for the world-class, national, and regional levels, respectively. In summary, world-class runners adopt a more aggressive pacing strategy and demonstrate greater fatigue than the less experienced runners; this might indicate a greater mental commitment and/or a better capacity to run under fatigue.

    2012-01-01

    There are multiple standards and formats for 3D models in virtual environments. The problem is that there is no open source platform for generating models out of discrete parts; this results in the process of having to "reinvent the wheel" when new games, virtual worlds and simulations want to enable their users to create their own avatars or easily customize in-world objects. OpenAvatar is designed to provide a framework to allow artists and programmers to create reusable assets which can be used by end users to generate vast numbers of complete models that are unique and functional. OpenAvatar serves as a framework which facilitates the modularization of 3D models allowing parts to be interchanged within a set of logical constraints.

    Full Text Available Occlusal plane is an essential consideration when multiple long-span posterior restorations are designed. When restorations are added to an existing tooth arrangement characterized by rotated, tipped, or extruded teeth, excursive interferences may be incorporated, resulting in detrimental squeal. The curve of Spee, which exists in the ideal natural dentition, allows harmony to exist between the anterior tooth and condylar guidance. This curve exists in the sagittal plane and is the best viewed from a lateral aspect. It permits total posterior disclusion on mandibular protrusion, given proper anterior tooth guidance. It is unclear that whether the curve of Spee is a description of the occlusal surface of each arch separately or in maximal intercuspation. The purpose of this study was to examine the differences in the depth of curve of Spee between the class I, class II, class III and to investigate the relationship of depth of curve of Spee with over jet, over-bite.

Para isso, utiliza dados e análises de pesquisas sobre transformações em ambientes de trabalho burocráticos, construção de espaços argumentativos dos gerentes, formas tradicionais e mais recentes do pequeno comércio e sobre o também recente fenômeno do desemprego gerencial. Procura entender o problema mediante um estudo de transformações das convenções cognitivas implícitas nas formas de se entender o mundo social e seus reflexos nas vivências da esfera econômica. Da análise emerge um interessante caso de cegueira institucional, onde todas as evidências que põem em xeque a nova ordem são descartadas e onde a antiga divisão das classes médias em estratos assalariados e autônomos tem de ser repensado.The text tries to analyse recent transformations in the manner how the Brazilian middle classes perceive and signify their lives in the economic sphere. For this I make use of dates and analyses produced in researches about the transformations of the bureaucratic-work milieu, about the construction of managers' argumentative spaces, about traditional and more recent forms of the small trade and about the also recent phenomenon of management unemployment. I try to understand the problem based on a study on the transformations of the cognitive conventions inherent to the way people comprehend the social world and experience the consequences of its changes in the economic sphere. The analysis shows that there exists an interesting case of institutional blindness in which all the evidences that threaten the new order are rejected and in which the old division of the middle classes between employed and autonomous strata has to be rethought.

  11. World War II Mobilization in Men's Work Lives: Continuity or Disruption for the Middle Class?

    Science.gov (United States)

    Dechter, Aimée R; Elder, Glen H

    2004-11-01

    The labor needs of World War II fueled a growing demand for both military and war industry personnel. This longitudinal study investigates mobilization into these competing activities and their work life effects among men from the middle class. Hazard estimates show significant differences in wartime activities across occupations, apart from other deferment criteria. By war's end, critical employment, in contrast to military service, is positively associated with supervisory responsibility for younger men and with occupation change. This empoloyment does not predict postwar career advancement up to the 1970s. By comparison, men who were officers had a "pipeline" to advancement after the war, whereas other service men fared worse than nonveterans.

    Science.gov (United States)

    Allen, Richard B

    2011-01-01

    In 1790, Marie Rozette, a freedwoman of Indian origin on Mauritius, executed a series of notarial acts which revealed that she possessed a small fortune in cash assets as well as slaves and substantial landed property in one of the island’s rural districts. The life of this former slave between 1776, when she first appears in the archival record, and her death in 1804 provides a vantage point from which to gain a subaltern perspective on aspects of Mascarene social and economic history, as well as developments in the wider Indian Ocean world during the late eighteenth and early nineteenth centuries. Marie Rozette’s life history challenges the notion that free persons of color in Mauritius were little more than an “unappropriated” people, and invites us to consider how supposedly marginalized individuals were able to cross various socio-economic and cultural boundaries. More specifically, her life affords an opportunity to consider the ways in which class, ethnicity, and gender, as well as race, interacted to create a distinctive Creole society in Mauritius, the nature and dynamics of which bear directly on our knowledge and understanding of the free colored experience elsewhere in the European colonial slave plantation world.

    This study reports the results of a content analysis of interviews with 28 Norwegian world-class athletes and 28 controls, matched for gender, age, and type of sport. Semi-structured interviews explored their perceptions of their best performance. The interviews were analyzed using the ATLAS.ti and yielded 20 higher-order codes. Nine higher-order codes were categorized as inner-oriented, five were categorized as outer-oriented, and six were a combination of inner- and outer-oriented. Statistical analysis, using the Mann-Whitney test, showed significant group differences for seven higher-order codes: (a) two outer-oriented codes relating to "mastery--achievements" and "training--outer"; and (b) five inner-oriented codes relating to "mental preparation," "self-reliance," "training--inner," "wholeness," "performance--inner," and "growth orientation." These findings highlight the importance of both inner- and outer-oriented development for high-level achievement in sports--the "mental game" is as important as the physical game, both during training and competitions. Previously published quantitative data reported higher levels of brain integration, faster habitation to a loud tone, and higher ego and moral development in these world-class athletes. These findings are interpreted in light of a Unified Theory of Performance, which proposes that higher mind-brain development provides a basis for higher performance in any activity.

    The present study investigated metabolic rate (MR) and gross efficiency (GE) at moderate and high work rates, and the relationships to gross kinematics and physical characteristics in elite cross-country skiers. Eight world class (WC) and eight national level (NL) male sprint cross-country skiers performed three 5-min stages using the skating G3 technique, whilst roller skiing on a treadmill. GE was calculated by dividing work rate by MR. Work rate was calculated as the sum of power against gravity and frictional rolling forces. MR was calculated using gas exchange and blood lactate values. Gross kinematics, i.e. cycle length (CL) and cycle rate (CR) were measured by video analysis. Furthermore, the skiers were tested for time to exhaustion (TTE), peak oxygen uptake (VO(2peak)), and maximal speed (V(max)) on the treadmill, and maximal strength in the laboratory. Individual performance level in sprint skating was determined by FIS points. WC skiers did not differ in aerobic MR, but showed lower anaerobic MR and higher GE than NL skiers at a given speed (all P < 0.05). Moreover, WC skiers skated with longer CL and had higher V(max) and TTE (all P < 0.05). In conclusion, the present study shows that WC skiers are more efficient than NL skiers, and it is proposed that this might be due to a better technique and to technique-specific power.

    The excellent motor skills of world class gymnasts amaze everyone. People marvel at the way they precisely control their movements and wonder how the brain structure and function of these elite athletes differ from those of non-athletes. In this study, we acquired diffusion images from thirteen world class gymnasts and fourteen matched controls, constructed their anatomical networks, and calculated the topological properties of each network based on graph theory. From a connectivity-based analysis, we found that most of the edges with increased connection density in the champions were linked to brain regions that are located in the sensorimotor, attentional, and default-mode systems. From graph-based metrics, we detected significantly greater global and local efficiency but shorter characteristic path length in the anatomical networks of the champions compared with the controls. Moreover, in the champions we found a significantly higher nodal degree and greater regional efficiency in several brain regions that correspond to motor and attention functions. These included the left precentral gyrus, left postcentral gyrus, right anterior cingulate gyrus and temporal lobes. In addition, we revealed an increase in the mean fractional anisotropy of the corticospinal tract in the champions, possibly in response to long-term gymnastic training. Our study indicates that neuroanatomical adaptations and plastic changes occur in gymnasts' brain anatomical networks either in response to long-term intensive gymnastic training or as an innate predisposition or both. Our findings may help to explain gymnastic skills at the highest levels of performance and aid in understanding the neural mechanisms that distinguish expert gymnasts from novices.

    The developmental practice patterns leading to the highest levels of success remain a subject of debate. The present study purposes to extend the body of empirical research by analysing athletic biographies from a large sample of German national squad athletes across all Olympic sports (n=1558; 57% male, 43% female). In a combined retrospective and longitudinal study utilising postal questionnaires, we evaluated the age at onset, volume, domain-specificity, variability in training and competition and success attained at different ages. Developmental practice patterns leading to rapid adolescent success and long-term senior success were inconsistent, and in some aspects contradictory. An early start-age for training and competition, early specialisation, high-intensity specific practice in the respective domain sport and little or no involvement in other sports (OS) favoured early adolescent success. Juvenile success, however, did not contribute to individual differences in success achieved at a senior age (-0.09world class performers differed from national class athletes in a later age for onset of training and competition in their domain sport, later specialisation (14.4 vs. 12.1 years), more involvement in OS (training 66% vs. 51%; competitions 53% vs. 39%), but not in practice volume in their domain sport at any age. Findings were confirmed with longitudinal testing and were widely consistent across types of sports. These findings are interpreted relative to correspondence to deliberate practice and DMSP frameworks while drawing on the concept of long-term sustainability.

  20. Intracellular recycling and cross-presentation by MHC class I molecules.

    2016-07-01

    Cross-presentation of internalized antigens by dendritic cells requires efficient delivery of Major Histocompatibility Complex (MHC) class I molecules to peptide-loading compartments. Strong evidence suggests that such loading can occur outside of the endoplasmic reticulum; however, the trafficking pathways and sources of class I molecules involved are poorly understood. Examination of non-professional, non-phagocytic cells has revealed a clathrin-independent, Arf6-dependent recycling pathway likely traveled by internalized optimally loaded (closed) class I molecules. Some closed and all open MHC class I molecules travel to late endosomes to be degraded but might also partly be re-loaded with peptides and recycled. Studies of viral interference revealed pathways in which class I molecules are directed to degradation in lysosomes upon ubiquitination at the surface, or upon AP-1 and HIV-nef-dependent misrouting from the Golgi network to lysosomes. While many observations made in non-professional cells remain to be re-examined in dendritic cells, available evidence suggests that both recycling and neo-synthesized class I molecules can be loaded with cross-presented peptides. Recycling molecules can be recruited to phagosomes triggered by innate signals such as TLR4 ligands, and may therefore specialize in loading with phagocytosed antigens. In contrast, AP-1-dependent accumulation at, or trafficking through, a Golgi compartment of newly synthesized molecules appears to be important for cross-presentation of soluble proteins and possibly of long peptides that are processed in the so-called vacuolar pathway. However, significant cell biological work will be required to confirm this or any other model and to integrate knowledge on MHC class I biochemistry and trafficking in models of CD8(+) T-cell priming by dendritic cells.

    Laboratory studies have investigated how individuals with normal memory spans attained digit spans over 80 digits after hundreds of hours of practice. Experimental analyses of their memory skills suggested that their attained memory spans were constrained by the encoding time, for the time needed will increase if the length of digit sequences to be memorised becomes longer. These constraints seemed to be violated by a world-class memorist, Feng Wang (FW), who won the World Memory Championship by recalling 300 digits presented at 1 digit/s. In several studies we examined FW's memory skills underlying his exceptional performance. First FW reproduced his superior memory span of 200 digits under laboratory condition, and we obtained his retrospective reports describing his encoding/retrieval processes (Experiment 1). Further experiments used self-paced memorisation to identify temporal characteristics of encoding of digits in 4-digit clusters (Experiment 2), and explored memory encoding at presentation speeds much faster than 1 digit/s (Experiment 3). FW's superiority over previous digit span experts is explained by his acquisition of well-known mnemonic techniques and his training that focused on rapid memorisation. His memory performance supports the feasibility of acquiring memory skills for improved working memory based on storage in long-term memory.

    At the United Nations Millennium Summit in September of 2000, the world leaders agreed on an ambitious agenda for reducing poverty and improving lives: the Millennium Development Goals (MDGs), a list of issues they consider highly pernicious, threatening to human welfare and, thereby, to global security and prosperity. Among the eight goals are included fundamental human needs such as the eradication of extreme poverty and hunger, the promotion of gender equality, the reduction of child mortality and improvement of maternal health, and ensuring the sustainability of our shared environment. In order to help focus the efforts to meet these goals, the United Nations (UN) has established a set of eighteen concrete targets, each with an associated schedule. Among these is Target 10: "By 2015, reduce by half the proportion of people without access to safe drinking water." A closely related target of equal dignity was agreed at the World Summit on Sustainable Development (Johannesburg, September 2002): "By 2015, reduce by half the proportion of people without access to basic sanitation." One of the greatest successes in the development of Exploration-class technologies for closed-loop, sustainable support of long-duration human space missions has been the work both ESA and NASA have done in bioregenerative water reclamation (WRS), and secondarily, in solid-waste management. Solid-waste and WRS systems tend to be combined in the commercial world into the field of sanitation, although as we will see, the most essential principles of sustainable terrestrial sanitation actually insist upon the separation of solid and liquid excreta. Seeing the potential synergy between the space program ALS technologies developed for Mars and the urgent needs of hundreds of millions of people for secure access to clean water here on Earth, we set out to organize the adaptation of these technologies to help the United Nations Development Programme (UNDP) meet Target 10.

    2005-01-01

    Recent type Ia supernovas data seemingly favor a dark energy model whose equation of state w(z) crosses -1 very recently, which is a much more amazing problem than the acceleration of the universe. In this paper we show that it is possible to realize such a crossing without introducing any phantom component in a Gauss-Bonnet brane world with induced gravity, where a four-dimensional curvature scalar on the brane and a five-dimensional Gauss-Bonnet term in the bulk are present. In this realization, the Gauss-Bonnet term and the mass parameter in the bulk play a crucial role.

Salivary testosterone, cortisol, alpha-amylase, immunoglobulin A, chromogranin A, blood creatine kinase activity and profile of mood state were assessed at rest in 24 world-class level athletes during preparation (3 times in 3 months and pre-competitive (5 times in 5 weeks training periods. Total mood disturbance and fatigue perception were reduced, while immunoglobulin A (+61% and creatine kinase activity (+43% increased, and chromogranin A decreased (-27% during pre-competitive compared to preparation period. A significant increase in salivary testosterone (+9 to +15% and a decrease in testosterone/cortisol ratio were associated with a progressive reduction in training load during pre-competitive period (P < 0.05. None of the psycho-physiological parameters were significantly correlated to training load during the pre-competitive period. Results showed a lower adrenocortical response and autonomic activity, and an improvement of immunity status, in response to the reduction in training load and fatigue, without significant correlations of salivary hormones with training load. Our findings suggest that saliva composition is sensitive to training contents (season period but could not be related to workload resulting from track and field athletics training.

The aim of this study was to evaluate the metabolic and hematologic responses of world-class canoeists during a training session; (2) Methods: Blood samples were taken at different points and analyzed for their hematological properties, activities of selected enzymes, hormones, and metabolites; (3) Results: Muscle stress biomarkers were elevated in response to exercise which correlated with modifications in the profile of white blood cells, where a leukocyte rise was observed after the canoe session. These results were accompanied by an increase in other exercise intensity parameters such as lactatemia and ammonemia. Adrenocorticotropic hormone and cortisol increased during the exercise sessions. The acute rise in both erythrocytes and white blood profile were probably due to muscle cell damage, rather than hepatocyte integrity impairment; (4) Conclusion: The cellular and metabolic responses found here, together with effective nutrition support, are crucial to understanding the effects of exercise in order to assist in the creation of new training and recovery planning. Also we show that Sportomics is a primal tool for training management and performance improvement, as well as to the understanding of metabolic response to exercise. PMID:27845704

    The healthcare system in the United States is at a critical crossroads. Costs are rising, measures of healthcare quality are well below those of other industrialized nations, and public and regulatory scrutiny is increasing. Healthcare leaders are searching for more effective, efficient, and sustainable operational models to address the mounting challenges they face. We at Schneck Medical Center in Seymour, Indiana, chose the Baldrige Excellence Framework to guide our organization, to accelerate our performance improvement journey, and to create sustainable results in our core services. The Baldrige Framework uses a systematic approach to innovation and improvement in seven key management areas. These seven areas were leadership; strategic planning; customer focus; measurement, analysis, and knowl- edge management; workforce focus; operations focus; and results (Baldrige Performance Excellence Program 2015). In this article, we describe our Baldrige journey. We address why we chose to use the Framework, how we engaged our key stakeholders, and what challenges we faced and lessons we learned along the way. In addition, we detail how Schneck's focus on performance improvement has resulted in significant returns to the organization. Throughout the article, we refer to our pursuit of performance excellence as a "journey," and it is indeed just that. Quality improvement takes time, because it is a transformation with many steps. World-class performance is attainable only with years of work and constant refinement.

    The objective of this study was to characterize the mechanics of maximal running sprint acceleration in high-level athletes. Four elite (100-m best time 9.95-10.29 s) and five sub-elite (10.40-10.60 s) sprinters performed seven sprints in overground conditions. A single virtual 40-m sprint was reconstructed and kinetics parameters were calculated for each step using a force platform system and video analyses. Anteroposterior force (FY), power (PY), and the ratio of the horizontal force component to the resultant (total) force (RF, which reflects the orientation of the resultant ground reaction force for each support phase) were computed as a function of velocity (V). FY-V, RF-V, and PY-V relationships were well described by significant linear (mean R(2) of 0.892 ± 0.049 and 0.950 ± 0.023) and quadratic (mean R(2) = 0.732 ± 0.114) models, respectively. The current study allows a better understanding of the mechanics of the sprint acceleration notably by modeling the relationships between the forward velocity and the main mechanical key variables of the sprint. As these findings partly concern world-class sprinters tested in overground conditions, they give new insights into some aspects of the biomechanical limits of human locomotion.

    1984-01-01

    Blood lactate accumulation was studied during progressive arm exercise in male and female world class kayak paddlers (K male, K female, n = 11), weight-/power-lifters (WL/PL, n = 6), bodybuilders (BB, n = 8) and non-athletes (NA, n = 6). The heavy resistance trained athletes exhibited greater upper-body muscle volume than the other subject groups. During low submaximal exercise intensities, blood lactate concentrations were significantly lower both in male and female kayakers compared with WL/PL, BB, and NA. Mean values at 120 W were 1.9 (K male), 2.1 (K female), 4.8 (WL/PL), 4.5 (BB), and 5.1 (NA) mmol X l-1. At higher power outputs the difference between females and non-kayakers diminished, while the difference between K male and all other groups increased. Exercise tolerance was greatest in K male and was equal among the other groups. Our results suggest that factors other than the muscle mass per se involved in exercise are responsible for the blood lactate response during this kind of work. Moreover, the physiological response observed in kayakers probably represents the upper limit of man's ability to perform continuous progressive arm-cranking exercise.

    To determine the relationship that exists between VO2max and cycling economy/efficiency during intense, submaximal exercise in world-class road professional cyclists. METHODS Each of 11 male cyclists (26+/-1 yr (mean +/- SEM); VO2max: 72.0 +/- 1.8 mL x kg(-1) x min(-1)) performed: 1) a ramp test for O2max determination and 2) a constant-load test of 20-min duration at the power output eliciting 80% of subjects' VO2max during the previous ramp test (mean power output of 385 +/- 7 W). Cycling economy (CE) and gross mechanical efficiency (GE) were calculated during the constant-load tests. CE and GE averaged 85.2 +/- 2.3 W x L(-1) x min(-1) and 24.5 +/- 0.7%, respectively. An inverse, significant correlation was found between 1) VO2max (mL x kg(-0.32) x min(-1)) and both CE (r = -0.71; P = 0.01) and GE (-0.72; P = 0.01), and 2) VO2max (mL x kg(-1) x min(-1)) and both CE (r = -0.65; P = 0.03) and GE (-0.64; P = 0.03). A high CE/GE seems to compensate for a relatively low VO2max in professional cyclists.

    The Jiaodong gold deposits are currently the most important gold resources (with Au reserves of>4000 t) in China, and the leading gold-producing country globally (with Au production of w428 t in 2013). Jiaodong is also considered as perhaps the only world-class to giant gold accumulation on the planet where relatively young gold ores (ca. 130e120 Ma) were deposited in rocks that are 2 Ga older. The Xincheng world-class high-grade gold deposit, with a proven reserve of >200 t gold, is one of the largest deposits in the giant gold province of the Jiaodong Peninsula. It is located in the northwestern part of the Jiaobei Uplift, and hosted by ca. 132e123 Ma Xincheng quartz monzonites and monzogranites. Ore zones are structurally controlled by the NE-trending and NW-dipping Jiaojia Fault and subsidiary faults, and are mainly restricted to the footwall of the fault. The dominant disseminated-and stockwork-style ores are associated with strong sericitization, silicification, sulfidation and K-feldspathization, and minor carbonate wallrock alteration halos. The four mineralization stages are pyriteequartzesericite (stage 1), quartzepyrite (stage 2), quartzepolysulfide (stage 3) and quartzecarbonate (stage 4). Gold occurs dominantly as electrum, with lesser amounts of sulfide-hosted native gold and rare native silver and argentite, normally associated with pyrite, chalcopyrite, galena and sphalerite:the latter with proven resources of about 105 t Ag, 713 t Cu, and 5100 t S. There are three types of ore-related fluid inclusions: type 1 aqueous-carbonate (H2OeCO2), type 2 aqueous (liquid H2O þ vapor H2O), and type 3 CO2 (liquid CO2 and vapor CO2) inclusions. Homogeni-zation temperatures range from 221 to 304 ?C for type 1 inclusions, with salinities of 2.4e13.3 wt.%NaCl eq., and bulk densities of 0.858e1.022 g/cm3. The d34SCDT values of hydrothermal sulfides are 4.3e10.6&and d18O values of hydrothermal quartz have a median value of 13.0&. dD values of fluid inclusions in

    Blood lactate accumulation is associated with development of muscle fatigue and negatively correlated to endurance performance. No research has quantified the effects of lactate presence at moderate levels of lactate accumulation. The purpose of this study was to test whether 2 moderate blood lactate concentration levels affect running economy (RE) when running at the individual lactate threshold (LT). Seven male world class endurance athletes with an average V[Combining Dot Above]O2max of 80.7 ± 2.7 ml·kg·min or 5.8 ± 0.5 L·min participated in this study. After the V[Combining Dot Above]O2max test, the subjects were resting or walking and in a random order tested for RE at their LT velocity when the blood lactate level reached either 3 mmol·L or 5 mmol·L. After a new 5-minute exercising period at maximal aerobic velocity, the crossover lactate value RE testing was performed. Running economy was significantly (p ≤ 0.05) deteriorated from 0.668 ± 0.044 to 0.705 ± 0.056 ml·kg·m or 5.5% (p ≤ 0.05) for blood lactate level of 3 mmol·L compared with 5 mmol·L, respectively. Increased lactate level from 3 to 5 mmol·L is thus accompanied by deteriorated RE at LT running velocity. The deteriorated RE at moderate levels of lactate concentration emphasizes the importance of avoiding intensities above LT in the early parts of a dominantly aerobic endurance competition. It also emphasizes the importance of a high V[Combining Dot Above]O2max for aerobic endurance athletes and may partly explain the V[Combining Dot Above]O2 slow component as impaired RE.

  2. Some fundamental considerations on the dynamics of class B laser threshold crossing

    Puccioni, G P; Lippi, G L

    2016-01-01

    With the help of a simple rate equation model, we analyze the intrinsic dynamics of threshold crossing for Class B lasers. A thorough discussion of the characteristics and the limitations of this very commonly employed model, which provides excellent qualitative predictions on the laser behaviour, is offered. Approximate solutions for the population inversion and for the field intensity, up to the point where the latter reaches macroscopic levels, are found and discussed, together with the associated characteristic times. Numerical verifications test the accuracy of these solutions and confirm their validity. A discussion of the implications on threshold dynamics is presented, together with the motivation for focussing on this -- nowadays most common -- class of lasers.

    Identifying the anthropometric measures of successful and less successful handball players may be helpful in developing a talent identification and development model, allowing for the determination of key physical capacities required for elite performance. The purpose of the study was to describe the anthropometric characteristics, including age, standing stature, body mass and body mass index (BMI) in handball players who participated in the 2013 Men's Handball World Championships. Secondly, the objective was to identify the possible differences in these parameters in terms of individual playing positions (goalkeeper, back, center back, wing, line player). Rosters with handball player's age, standing stature, and body mass were obtained from the International Handball Federation website. The research material included 409 handball players (24 teams). National teams were organized by their ranks and sub-grouped using their continents and playing positions. The results of the analyses of variance demonstrated significant differences in age (F=2.30; p=0.044; Partial ŋ2=0.028), standing stature (F=14.02; p=0.0001; Partial ŋ2=0.148), and body mass (F=5.88; p=0.0001; Partial ŋ2=0.068) among the groups (G1-G6). Players in G1 had the highest standing stature and body mass, while players in G6 had the lowest age and body mass values. The backs and line players were the tallest. In addition, the measurement of body mass showed that the line players had the highest body mass and BMI values. In conclusion, this study presented anthropometric data that differentiated levels of success in male handball teams playing in the 2013 world championships. This information should serve as a reference for the average standing stature, body mass, and BMI of handball players for particular positions at the professional level.

    The essay is an empirical case study of famed British scientist Francis Crick. Viewing him as a 'cross-worlds influencer' who was moreover dedicated to a cause, I have tried to understand how these two characteristics influenced the trajectory of his long career and how they shaped his contributions to the diverse research fields in which he was active, and concluded that these characteristics reconfigure Crick's career into a coherent whole. First, I identify a major thread running through Crick's career: helping organise 'un-disciplined' new research fields, and show that his successive choices were not serendipitous but motivated by what he construed as a crusade against 'vitalism': anti-vitalism was a defining driver of his career. I then examine how Crick put his skills as a crossworlds influencer to the service of his cause, by helping organise his chosen fields of intervention. I argue that his activities as a cross-worlds influencer were an integral part of his way of 'doing science' and that his contributions to science, neuroscience in particular, should be re-evaluated in this light. This leads me to advance a possible strategy for historians to investigate big bioscience fields. Following Abir-Am, I propose to trace their genealogies back to the fluctuating semi-institutional gatherings and the institutional structures that sustained them. My research on Crick supports the view that such studies can bring insights into the question of why the contours of contemporary big bioscience endeavours have come to be shaped the way they are. Further, the essay provides a heuristic device for approaching these enquiries: 'follow the cross-worlds influencers' who worked to build and organise these semi-institutional gatherings and institutional structures.

    This article provides an insight into the support needs of health and social care commissioners seeking to develop world class commissioning competencies and the role of service improvement agencies in meeting these needs. Reporting findings from the evaluation of one service improvement agency based in England, we focus on the 'improvement supports' (the products and services) that were delivered by the 'Care Services Improvement Partnership' through its 'Better Commissioning Programme'. In-depth interviews were carried out with 25 care commissioners (n = 25) exploring how the Programme was used in their day to day work, its perceived value and limitations. Given the lack of employer-led training and induction we conclude that service improvement agencies play an important role in developing commissioners' skills and competencies. However, we suggest that achieving world class commissioning may depend on a more fundamental rethink of commissioning organisations' approaches to learning and development.

    During early adulthood, individuals from different cultures across the world tend to become more agreeable, more conscientious, and less neurotic. Two leading theories offer different explanations for these pervasive age trends: Five-factor theory proposes that personality maturation is largely determined by genetic factors, whereas social-investment theory proposes that personality maturation in early adulthood is largely the result of normative life transitions to adult roles. In the research reported here, we conducted the first systematic cross-cultural test of these theories using data from a large Internet-based sample of young adults from 62 nations (N = 884,328). We found strong evidence for universal personality maturation from early to middle adulthood, yet there were significant cultural differences in age effects on personality traits. Consistent with social-investment theory, results showed that cultures with an earlier onset of adult-role responsibilities were marked by earlier personality maturation.

    We propose a modified time lag random matrix theory in order to study time-lag cross correlations in multiple time series. We apply the method to 48 world indices, one for each of 48 different countries. We find long-range power-law cross correlations in the absolute values of returns that quantify risk, and find that they decay much more slowly than cross correlations between the returns. The magnitude of the cross correlations constitutes "bad news" for international investment managers who may believe that risk is reduced by diversifying across countries. We find that when a market shock is transmitted around the world, the risk decays very slowly. We explain these time-lag cross correlations by introducing a global factor model (GFM) in which all index returns fluctuate in response to a single global factor. For each pair of individual time series of returns, the cross correlations between returns (or magnitudes) can be modeled with the autocorrelations of the global factor returns (or magnitudes). We estimate the global factor using principal component analysis, which minimizes the variance of the residuals after removing the global trend. Using random matrix theory, a significant fraction of the world index cross correlations can be explained by the global factor, which supports the utility of the GFM. We demonstrate applications of the GFM in forecasting risks at the world level, and in finding uncorrelated individual indices. We find ten indices that are practically uncorrelated with the global factor and with the remainder of the world indices, which is relevant information for world managers in reducing their portfolio risk. Finally, we argue that this general method can be applied to a wide range of phenomena in which time series are measured, ranging from seismology and physiology to atmospheric geophysics.

    2014-06-01

    Public perceptions of the work of nurses and VAD-volunteers in the First World War have been heavily influenced by a small number of VAD-writings. The work of trained, professional nurses in supporting and supervised the work of VADs has been largely overlooked. This paper examines several of the writings of both volunteers and professionals, and emphasises the overlooked supervisory, managerial and clinical work of trained nurses. In this centenary year of the First World War's opening months, the paper also explores the ways in which the British mass-media--notably the BBC--have chosen to cling to a romantic image of the untrained nurse, whilst at the same time acknowledging the significance of trained, professional nursing.

    The present work demonstrates that antibody-induced cross-linking of MHC class I antigens on Jurkat T lymphoma cells leads to a rise in intracellular calcium (Cai2+) and, in the presence of phorbol ester (PMA), to IL-2 production and IL-2 receptor expression. The rise in Cai2+ exhibited a profile...... very different from that obtained after anti-CD3 antibody-induced activation suggesting that activation signals are transduced differently after binding of anti-CD3 antibody and class I cross-linking, respectively. However, when Cai2+ was examined in individual Jurkat cells by means of a digital image...

    2017-03-01

    The Jinding Zn-Pb sediment-hosted deposit in western Yunnan, China, is the fourth largest Zn deposit in Asia. Based on field observations of the ore textures, breccias, and the sandstone host rocks, the ores formed in a dome that was created by the diapiric migration of evaporites in the Lanping Basin during Paleogene deformation and thrust loading. Most of the ore occurs in sandstones that are interpreted to be a former evaporite glacier containing a mélange of extruded diapiric material, including breccias, fluidized sand, and evaporites that mixed with sediment from a fluvial sandstone system. A pre-ore hydrocarbon and reduced sulfur reservoir formed in the evaporite glacier that became the chemical sink for Zn and Pb in a crustal-derived metalliferous fluid. In stark contrast to previous models, the Jinding deposit does not define a unique class of ore deposits; rather, it should be classified as MVT sub-type hosted in a diapiric environment. Given that Jinding is a world-class ore body, this new interpretation elevates the exploration potential for Zn-Pb deposit in other diapir regions in the world.

    The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30-15.07) and sex (female) (OR 4.62, 90% CI 1.15-18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage.

    Little is known about the rate and pattern of injuries in international volleyball competition. To describe the risk and pattern of injuries among world-class players based on data from the The International Volleyball Federation (FIVB) Injury Surveillance System (ISS) (junior and senior, male and female). The FIVB ISS is based on prospective registration of injuries by team medical staff during all major FIVB tournaments (World Championships, World Cup, World Grand Prix, World League, Olympic Games). This paper is based on 4-year data (September 2010 to November 2014) obtained through the FIVB ISS during 32 major FIVB events (23 senior and 9 junior). The incidence of time-loss injuries during match play was 3.8/1000 player hours (95% CI 3.0 to 4.5); this was greater for senior players than for junior players (relative risk: 2.04, 1.29 to 3.21), while there was no difference between males and females (1.04, 0.70 to 1.55). Across all age and sex groups, the ankle was the most commonly injured body part (25.9%), followed by the knee (15.2%), fingers/thumb (10.7%) and lower back (8.9%). Injury incidence was greater for centre players and lower for liberos than for other player functions; injury patterns also differed between player functions. Volleyball is a very safe sport, even at the highest levels of play. Preventive measures should focus on acute ankle and finger sprains, and overuse injuries in the knee, lower back and shoulder.

  7. Real-world educational experience through project-oriented graduate classes in collaboration with industry

    Zurbuchen, Thomas H.

    2007-04-01

    There is a need for a motivated and innovative work force for the U.S. aerospace industry. The education of such engineers and scientists typically revolves around a fundamental knowledge of basic important technologies, such as the mechanics relevant to orbit-design, structures, avionics, and many others. A few years ago, the University of Michigan developed a Masters of Engineering program that provides students with skills that are not taught as part of a typical engineering curriculum. This program is focused on open problem solving, space systems, and space policy, as well as other classes that further their understanding of the connections between technologies and the nontechnical aspects of managing a space mission. The value of such an education is substantially increased through a direct connection to industry. An innovative problem-oriented approach has been developed that enables direct connections between industry and classroom teaching. The class works as a system study group and addresses problems of interest to and defined by a company with a specific application. We discuss such an application, a near-space lidar wind measurement system to enhance weather predictions, as well as the approach taken to link educational rationales.

  8. A world class nuclear research reactor complex for South Africa's nuclear future

    2008-07-01

    South Africa recently made public its rather ambitious goals pertaining to nuclear energy developments in a Draft Policy and Strategy issued for public comment. Not much attention was given to an important tool for nuclear energy research and development, namely a well equipped and maintained research reactor, which on its own does not do justice to its potential, unless it is fitted with all the ancillaries and human resources as most first world countries have. In South Africa's case it is suggested to establish at least one Nuclear Energy Research and Development Centre at such a research reactor, where almost all nuclear energy related research can be carried out on par with some of the best in the world. The purpose of this work is to propose how this could be done, and motivate why it is important that it be done with great urgency, and with full involvement of young professionals, if South Africa wishes to face up to the challenges mentioned in the Draft Strategy and Policy.

    Full Text Available Consumer audio amplifiers are intended to op¬erate with various loudspeaker loads, i.e. the load imped¬ance profile of the audio amplifier is a priori unknown. We propose the power parameters analysis of the class B audio amplifiers to be carried out in the realistic worst-case (RWC scenario of operation with the minimal value of the impedance and a RWC type of signal, instead of the nominal impedance of the loudspeaker and a sine-wave signal. Experimental validation, carried out for different types of signals and loudspeaker loads, demonstrate the advantages of the proposed RWC-based power parameters estimation. Furthermore, we provide a way of assessing the safe-operating area (SOA boundaries, based on the output I-V loci of the amplifier and by means of an equi¬valent load line (ELL.

    Siguiri is a world-class orogenic gold district hosted in the weakly metamorphosed Upper Birimian to Lower Tarkwa Group sedimentary rocks of the Siguiri Basin (Guinea). The district is characterised by a protracted deformation history associated with four main deformation events: D1S is a N-S compression; D2S is an E-W compression progressively evolving into an early-D3S transpression and then into a late-D3S NNW-SSE transtension and D4S is a NE-SW compression. Field observations, petrography and geochemistry at three key deposits of the Siguiri district (Bidini, Sintroko PB1 and Kosise) suggest a polyphase hydrothermal history that can be subdivided into four hydrothermal events. The first hydrothermal event was associated with the development of barren bedding-parallel and en-echelon V2S quartz-dominated-(pyrite) veins. The second hydrothermal event is characterised by the development of V3A pyrite-ankerite veins late during D3S. Laser ablation-ICP-MS data show that this vein set contains high gold contents of up to 43.3 ppm, in substitution in pyrite crystal lattice, representing a minor first gold mineralisation event. The third and most prominently developed hydrothermal event is late D3S and represents the second and principal gold mineralisation event. This mineralisation event led to two distinct mineralisation textures. The first texture is best exposed in the Kosise deposit and is characterised by gold-bearing quartz-ankerite-arsenopyrite conjugate V3B veins. Although the bulk of the gold is hosted in native gold grains in V3B veins, LA-ICP-MS analyses show that gold also substitutes in the arsenopyrite crystal lattice (up to 55.5 ppm). The second mineralisation texture is best expressed in the Sanu Tinti deposit and consists of disseminated barren pyrite hosted in a polymict conglomerate. The second and third hydrothermal events are both structurally controlled by a series of early-D3S N-S, NE-SW, WNW-ESE and E-W sub-vertical incipient structures

    This paper presents the results of a massive open online class (MOOC) on astronomy called Astronomy: Exploring Time and Space. The class was hosted by the web platform Coursera and ran for six weeks from February to May 2015. Coverage was designed to emphasise topics in astronomy where there has been rapid research progress, including large telescopes, exploration of the Solar System, the discovery of exoplanets, exotic end states of stars, and the frontiers of cosmology. The core content was nearly eighteen hours of video lectures, assessed by thirteen video lecture quizzes, three peer review writing assignments, and two online activities. Information on demographics and on the goals and motivations of the learners was gathered using standard Coursera entry and exit surveys and an external Science Literacy survey. A total of 25 379 people registered for the course, and most of them did not complete any assignments. About two-thirds of the 14 900 learners who opened the course lived outside the United States, distributed across 151 different countries. Out of 4275 participants who completed one or more assignments, 1607 passed the course, and a majority did so with a grade of 80% or higher. Those who completed the course were generally very satisfied with their experience and felt it met their learning goals. The people with the highest chance of completing the course tended to be in the range 40 to 60 years old, had a college education, and were either retired or working in professional fields. The strongest predictors of passing the course were to have completed the first written assignment or the first online activity.

    Paralympic Cross-Country sit-skiers use adaptive equipment, with a resulting gesture similar to double poling techniques adopted by able-bodied skiers. Despite the similarity, a specific attention on the gesture performed by sit-skiers is needed. The paper focuses on the sledge kinematic and on inertia effect of upper body motion which is translated in a propulsive effect in the early stage of the pushing cycle. In particular a group of 7 elite sit skiers of class LW10 were recorded with a video-based markerless motion capture technique during 1 km sprint Paralympic race. A biomechanical model, consisting of 7 anatomical points and 4 technical ones, is used to track the kinematics from video-images, then body segments, joints of interest and relative angles are evaluated. In this paper we focus on the biomechanics of the poling cycle, in particular prior to the onset of pole plant. The aim was to evaluate the contribution of the upper body to the early stage of the propulsive action. To this porpoise body inertial forces for each athlete are calculated using kinematic data, then normalized with respect to the athlete's body mass. The results show that in LW10 sit-skiers an important sledge propulsion, prior to the onset of pole plant, is provided by the inertial effect, due to the upper body region (arms and forearms) motion.

    High levels of social capital and social integration are associated with self-rated health in many developed countries. However, it is not known whether this association extends to non-western and less economically advanced countries. We examine associations between social support, volunteering, and self-rated health in 139 low-, middle- and high-income countries. Data come from the Gallup World Poll, an internationally comparable survey conducted yearly from 2005 to 2009 for those 15 and over. Volunteering was measured by self-reports of volunteering to an organization in the past month. Social support was based on self-reports of access to support from relatives and friends. We started by estimating random coefficient (multi-level) models and then used multivariate logistic regression to model health as a function of social support and volunteering, controlling for age, gender, education, marital status, and religiosity. We found statistically significant evidence of cross-national variation in the association between social capital variables and self-rated health. In the multivariate logistic model, self-rated health were significantly associated with having social support from friends and relatives and volunteering. Results from stratified analyses indicate that these associations are strikingly consistent across countries. Our results indicate that the link between social capital and health is not restricted to high-income countries but extends across many geographical regions regardless of their national-income level.

  19. Autophagy and proteasome interconnect to coordinate cross-presentation through MHC class I pathway in B cells.

    Cross-presentation of exogenous protein antigens by B cells through the major histocompatibility complex (MHC) class I pathway in lymphoid malignancies, and transplant setting has been recognised as an important mediator of immune pathogenesis and T cell-mediated immune regulation. However, the precise mechanism of cross-presentation of exogenous antigens in B cells has remained unresolved. Here we have delineated a novel pathway for cross-presentation in B cells, which involves synergistic cooperation of the proteasome and autophagy. After endocytosis, protein antigen is processed through an autophagy- and proteasome-dependent pathway and CD8(+) T-cell epitopes are loaded onto MHC class I molecules within the autophagolysomal compartment rather than the conventional secretory pathway, which requires transporters associated with antigen processing-dependent transport. Interestingly, this cross-presentation was critically dependent on valosin-containing protein (VCP)/p97 ATPase through its participation in autophagy. Loss of VCP/p97 ATPase was coincident with accumulation of LC3-II and marked reduction in antigen presentation. These observations provide unique insight on how the autophagy and proteasomal degradation systems interconnect to coordinate MHC class I-restricted cross-presentation in B cells.

  3. Creating World-Class Gathering Places for People and Wildlife along the Detroit Riverfront, Michigan, USA

    2015-11-01

    Full Text Available Metropolitan Detroit, Michigan, USA is the automobile capital of the world, part of the industrial heartland and Rust Belt, and a major urban area. For over two centuries, the Detroit River was perceived as a working river that supported commerce and industry. Like many other large North American cities, the Motor City made the Detroit River its back door, with businesses facing inland and away from the river. Compounding the problem, Detroit became indifferent to the water pollution that was perceived as a necessary by-product of industrial progress. By the 1960s, the Detroit River was one of the most polluted rivers in North America. Today, the cleanup and recovery of the Detroit River represent one of the most remarkable ecological recovery stories in North America with the return of bald eagles, peregrine falcons, osprey, lake sturgeon, lake whitefish, mayflies, and more. Out of this recovery has come two transformational projects—the Detroit River International Wildlife Refuge and the Detroit RiverWalk—that are helping change the perception of the region from that of a Rust Belt city to one of a leader of urban sustainability that reconnects people to nature, improves quality of life, promotes sustainable redevelopment, and enhances community pride. Key lessons learned include: recruit a well-respected champion; ensure broad support from key stakeholder groups; establish core delivery team, focused on outcomes; build trust; adopt a strategic approach to community engagement, creating a connected community; evoke a sense of place; and measure and celebrate successes to sustain momentum.

    Genes encoded by the major histocompatibility complex (MHC) play key roles in the vertebrate immune system. However, our understanding of the evolutionary processes and underlying genetic mechanisms shaping these genes is limited in many taxa, including amphibians, a group currently impacted by emerging infectious diseases. To further elucidate the evolution of the MHC in frogs (anurans) and develop tools for population genetics, we surveyed allelic diversity of the MHC class II ??1 domain in both genomic and complementary DNA of seven New World species in the genus Rana (Lithobates). To assign locus affiliation to our alleles, we used a "gene walking" technique to obtain intron 2 sequences that flanked MHC class II?? exon 2. Two distinct intron sequences were recovered, suggesting the presence of at least two class II?? loci in Rana. We designed a primer pair that successfully amplified an orthologous locus from all seven Rana species. In total, we recovered 13 alleles and documented trans-species polymorphism for four of the alleles. We also found quantitative evidence of selection acting on amino acid residues that are putatively involved in peptide binding and structural stability of the ??1 domain of anurans. Our results indicated that primer mismatch can result in polymerase chain reaction (PCR) bias, which influences the number of alleles that are recovered. Using a single locus may minimize PCR bias caused by primer mismatch, and the gene walking technique was an effective approach for generating single-copy orthologous markers necessary for future studies of MHC allelic variation in natural amphibian populations. ?? 2010 Springer-Verlag.

This empirical study aims to assess how TQM—a holistic management philosophy initially developed by W. Edward Deming, which integrates improvement strategy, management practices, and organizational performance—is specifically implemented in the oil and gas companies operating in Indonesia. Relevant literature on the TQM, the world-class performance in operations (world-class company and operational performance, the company performance (financial and non-financial performances, and the amendments of the Law of the Republic of Indonesia concerning the oil and gas industry, and related research on how the oil and gas industry in Indonesia develops sustainable competitive advantage and sustainable development programs are reviewed in details in our study. The findings from data analysis provide evidence that there is a strong positive relationship between the critical factors of quality management practices and the company financial performance mediated by the three mediating variables, i.e., world-class company practices, operational excellence practices, and company non-financial performance.

    The mechanism of how superantigens function to activate cells has been linked to their ability to bind and cross-link the major histocompatibility complex class II (MHCII) molecule. Cells that lack the MHCII molecule also respond to superantigens, however, with much less efficiency. Therefore, the purpose of this study was to confirm that staphylococcal enterotoxin A (SEA) could bind the MHCI molecule and to test the hypothesis that cross-linking SEA bound to MHCII-deficient macrophages would induce a more robust cytokine response than without cross-linking. We used a capture enzyme-linked immunosorbent assay and an immunprecipitation assay to directly demonstrate that MHCI molecules bind SEA. Directly cross-linking MHCI using monoclonal antibodies or cross-linking bound SEA with an anti-SEA antibody or biotinylated SEA with avidin increased TNF-alpha and IL-6 secretion by MHCII(-/-) macrophages. The induction of a vigorous macrophage cytokine response by SEA/anti-SEA cross-linking of MHCI offers a mechanism to explain how MHCI could play an important role in superantigen-mediated pathogenesis.

    To examine patterns of conflict-related violence and intimate partner violence (IPV) and their associations with emotional distress among Congolese refugee women living in Rwanda. Cross-sectional study. Two Congolese refugee camps in Rwanda. 548 ever-married Congolese refugee women of reproductive age (15-49 years) residing in Rwanda. Our primary outcome was emotional distress as measured using the Self-Report Questionnaire-20 (SRQ-20). For analysis, we considered participants with scores greater than 10 to be experiencing emotional distress and participants with scores of 10 or less not to be experiencing emotional distress. Almost half of women (49%) reported experiencing physical, emotional or sexual violence during the conflict, and less than 10% of women reported experiencing of any type of violence after fleeing the conflict. Lifetime IPV was reported by approximately 22% of women. Latent class analysis derived four distinct classes of violence experiences, including the Low All Violence class, the High Violence During Conflict class, the High IPV class and the High Violence During and After Conflict class. In multivariate regression models, latent class was strongly associated with emotional distress. Compared with women in the Low All Violence class, women in the High Violence During and After Conflict class and women in the High Violence During Conflict had 2.7 times (95% CI 1.11 to 6.74) and 2.3 times (95% CI 1.30 to 4.07) the odds of experiencing emotional distress in the past 4 weeks, respectively. Furthermore, women in the High IPV class had a 4.7 times (95% CI 2.53 to 8.59) greater odds of experiencing emotional distress compared with women in the Low All Violence class. Experiences of IPV do not consistently correlate with experiences of conflict-related violence, and women who experience high levels of IPV may have the greatest likelihood for poor mental health in conflict-affected settings.

    Directory of Open Access Journals (Sweden)

    Cézaire Aimé Adiko

    2015-07-01

    Full Text Available Cross-presentation, in which exogenous antigens are presented via MHC I complexes, is involved both in the generation of anti-infectious and anti-tumoral cytotoxic CD8+ T cells and in the maintenance of immune tolerance. While cross-presentation was described almost four decades ago and while it is now established that some dendritic cell subsets are better than others in processing and cross-presenting internalized antigens, the involved molecular mechanisms remain only partially understood. Some of the least explored molecular mechanisms in cross-presentation concern the origin of cross-presenting MHC I molecules and the cellular compartments where antigenic peptide loading occurs. This review focuses on MHC I molecules and their intracellular trafficking. We discuss the source of cross-presenting MHC I in dendritic cells as well as the role of the endocytic pathway in their recycling from the cell surface. Next, we describe the importance of the TAP peptide transporter for delivering peptides to MHC I during cross-presentation. Finally, we highlight the impact of innate immunity mechanisms on specific antigen cross-presentation mechanisms in which TLR activation modulates MHC I trafficking and TAP localization.

  11. Building a World-Class Safety Culture: The National Ignition Facility and the Control of Human and Organizational Error

    Bennett, C T; Stalnaker, G

    2002-12-06

    Accidents in complex systems send us signals. They may be harbingers of a catastrophe. Some even argue that a ''normal'' consequence of operations in a complex organization may not only be the goods it produces, but also accidents and--inevitably--catastrophes. We would like to tell you the story of a large, complex organization, whose history questions the argument ''that accidents just happen.'' Starting from a less than enviable safety record, the National Ignition Facility (NIF) has accumulated over 2.5 million safe hours. The story of NIF is still unfolding. The facility is still being constructed and commissioned. But the steps NIF has taken in achieving its safety record provide a principled blueprint that may be of value to others. Describing that principled blueprint is the purpose of this paper. The first part of this paper is a case study of NIF and its effort to achieve a world-class safety record. This case study will include a description of (1) NIF's complex systems, (2) NIF's early safety history, (3) factors that may have initiated its safety culture change, and (4) the evolution of its safety blueprint. In the last part of the paper, we will compare NIF's safety culture to what safety industry experts, psychologists, and sociologists say about how to shape a culture and control organizational error.

    This study aimed to compare the force (F)-velocity (v)-power (P)-time (t) relationships of female and male world-class sprinters. A total of 100 distance-time curves (50 women and 50 men) were computed from international 100-m finals, to determine the acceleration and deceleration phases of each race: (a) mechanical variables describing the velocity, force, and power output; and (b) F-P-v relationships and associated maximal power output, theoretical force and velocity produced by each athlete (Pmax , F0 , and V0 ). The results showed that the maximal sprint velocity (Vmax ) and mean power output (W/kg) developed over the entire 100 m strongly influenced 100-m performance (r > -0.80; P ≤ 0.001). With the exception of mean force (N/kg) developed during the acceleration phase or during the entire 100 m, all of the mechanicals variables observed over the race were greater in men. Shorter acceleration and longer deceleration in women may explain both their lower Vmax and their greater decrease in velocity, and in turn their lower performance level, which can be explained by their higher V0 and its correlation with performance. This highlights the importance of the capability to keep applying horizontal force to the ground at high velocities.

    Full Text Available Abstract Background Examining the association between social inequality and health is not new. However, there is little empirical evidence of this association in the Latin American literature, much less from the Mexican scholars. Its research, including the one conducted in Mexico, has mostly followed a theoretical approach and has not been able to provide strong empirical evidence of their important theoretical and conceptual contributions, mainly because reliable, complete and valid data are unavailable. Methods To empirically examine the gradient effect of social class on self-rated health in Mexico, a secondary cross-sectional mixed-level analysis was designed. Using individual level data from the Second National Health Survey (ENSA II, social class categories were specified following a stratification approach according to the occupation and education indicators available from ENSA II. Two types of categories were made, one for t urban and one for the rural labor force. Two indicators of perceived health status were used as health outcomes: self-assessed health and reported morbidity. Furthermore, the marginality index, an indicator of relative deprivation was used to examine its contextual effect at the state and regional level. The analysis was conducted using logistic multivariate models. Results The cross-sectional analysis showed a gradient effect of social class for good assessed-health. Relative to the low urban class, the odds ratio (OR for a good perception of health for individuals belonging to the high urban class was 2.9 (95% confidence interval: 2.1–3.9. The OR for the middle high class was 2.8 (95% confidence interval: 2.4–3.4, while the OR for the middle low class was 1.8 (95% confidence interval: 1.6–2.1. However, for the rural labour force an OR of 1.5 was only significant between the high class who considered their health as good relative to the low class (95% confidence interval: 1.02–2.2.

We compare the energy missing signature with the standard model background pp → jet + vbar v, which was simulated at CompHep. We show that the models with numbers of compact extra dimensions greater than 4 can be probed at the protons center-of-mass energy equal 14 TeV. We also find that testing the brane-world models at 7 TeV on the LHC appears to hopeless.

    To investigate on-ice repeated-sprint and sports-specific-technique abilities and the relationships to aerobic and anaerobic off-ice capacities in world-class ice sledge hockey players. Twelve Norwegian national team players performed 8 repeated maximal 30-m sprints and a sports-specific-technique test while upper-body poling on ice, followed by 4 maximal upper-body strength tests and 8-s peak power and 3-min peak aerobic-capacity (VO2peak) tests while ergometer poling. The fastest 30-m sprint time was 6.5 ± 0.4 s, the fastest initial 10-m split-time 2.9 ± 0.2 s, and the corresponding power output 212 ± 37 W. Average 30-m time during the 8 repeated sprints was 6.7 ± 0.4 s, and the sprint-time decrement was 4.3% ± 1.8%. Time to execute the sport-specific-technique test was 25.6 ± 2.7 s. Averaged 1-repetition-maximum strength of the 4 exercises correlated with the fastest 30-m sprint time (r = -.77), the fastest initial 10-m split time (r = -.72), the corresponding power output (r = .67), and the average 30-m sprint time (r = -.84) (all P sprint test correlated with the highest initial 10-m power (r = .83, P sprint time (r = -.68, P sprint-time decrement. All off-ice variables except VO2peak correlated with technique-test time (r = -.58 to .73, all P ability to sprint fast and rapid execution of a technically complex test, whereas mode-specific endurance capacity is particularly important for maintenance of sprint ability in ice sledge hockey.

    Jiaodong peninsula, located at the southeastern margin of the North China Craton, is well known for its rich endowment of super-large gold deposits. This region is also characterized by hundreds of intermediate - mafic dykes that cluster into several dyke swarms. In this study, we present zircon U-Pb ages which show that the timing of dyke emplacement as ca. 120 Ma, which followed the crystallization of the (quartz-) diorite porphyry at ca. 130 Ma. These ages coincide with the peak ages reported for magmatism and metallogeny in the central North China Craton. The various ages (2450-2570 and 154 Ma) from the inherited zircon crystals in these rocks suggest that substantial lower to middle crustal basement rocks and Jurassic granitoids were involved during dyke emplacement. The dyke swarms, varying between alkaline and subalkaline, are compositionally low-Si low-Ti lamprophyre and low-Si high-Ti dolerite porphyry in the western of the Jiaodong peninsula, whereas those in the eastern part are composed of both high-Si low-Ti and low-Si high-Ti lamprophyres. These features imply multiple sources for the dykes from convective asthenospheric mantle to ancient enriched lithospheric mantle with magma generation at different depths involving mixture of slab-derived hydrous fluids. The source magmas of the dykes were hydrous and enriched in volatiles as well as ore components, and their evolution occurred under high oxygen fugacity conditions. The relatively rapid emplacement and cooling of the dyke systems enabled the migration of fluids into ore-controlling faults or fractures. We envisage that the dyke swarms played an important role in generating the world-class gold mineralization of Jiaodong.

    In this paper we propose a latent class distance association model for clustering in the predictor space of large contingency tables with a categorical response variable. The rows of such a table are characterized as profiles of a set of explanatory variables, while the columns represent a single outcome variable. In many cases such tables are sparse, with many zero entries, which makes traditional models problematic. By clustering the row profiles into a few specific classes and representing these together with the categories of the response variable in a low-dimensional Euclidean space using a distance association model, a parsimonious prediction model can be obtained. A generalized EM algorithm is proposed to estimate the model parameters and the adjusted Bayesian information criterion statistic is employed to test the number of mixture components and the dimensionality of the representation. An empirical example highlighting the advantages of the new approach and comparing it with traditional approaches is presented.

    This paper aims to show the system for relief provided by the Japanese Red Cross relief units during the Second World War, as well as the actual activities of sixteen of its relief units dispatched to Burma. The Red Cross wartime relief efforts involved using personnel and funding prepared beforehand to provide aid to those injured in war, regardless of their status as ally or enemy. Thus they were able to receive support from the army in order to ensure safety and provide supplies. Nurses dispatched to Burma took care of many patients who suffered from malnutrition and physical injuries amidst the outbreak of infectious diseases typical of tropical areas, without sufficient replacement members. Base hospitals not meant for the front lines also came under attack, and the nurses' lives were thus in mortal danger. Of the 374 original members, 29 died or went missing in action.

    Lymphocytes of a New World primate, the cotton-top tamarin (Saguinus oedipus), express classical G-related major histocompatibility complex (MHC) class I molecules with unusually limited polymorphism and variability. Three G-related loci, an F locus, an E locus, and two pseudogenes (So-N1 and So-N3) have been identified by cDNA library screening and extensive PCR analysis of both cDNA and genomic DNA from the cotton-top tamarin. Furthermore, each genus of the subfamily Callitrichinae (tamarins and marmosets) appears to express its own unique set of MHC class I genes, likely due to a rapid turnover of loci. The rapid emergence of unique MHC class I genes in the Callitrichinae genera, resulting from an active process of duplication and inactivation of loci, may account for the limited diversity of the MHC class I genes in the cotton-top tamarin. To determine the nature of the entire complement of MHC class I genes in the cotton-top tamarin, we synthesized a genomic DNA library and screened it with MHC class I-specific probes. We isolated nine new MHC class I pseudogenes from this library. These newly isolated tamarin G-related MHC class I pseudogenes are not closely related to any of their functional counterparts in the tamarin, suggesting that they do not share a recent common ancestral gene with the tamarin's currently expressed MHC class I loci. In addition, these tamarin sequences display a high rate of nonsynonymous substitutions in their putative peptide binding region. This indicates that the genes from which they have derived were likely subject to positive selection and, therefore, were once functional. Our data support the notion that an extremely high rate of loci turnover is largely responsible for the limited diversity of the MHC class I genes in the cotton-top tamarin.

    Structural class characterizes the overall folding type of a protein or its domain. Many methods have been proposed to improve the prediction accuracy of protein structural class in recent years, but it is still a challenge for the low-similarity sequences. In this study, we introduce a feature extraction technique based on auto cross covariance (ACC) transformation of position-specific score matrix (PSSM) to represent a protein sequence. Then support vector machine-recursive feature elimination (SVM-RFE) is adopted to select top K features according to their importance and these features are input to a support vector machine (SVM) to conduct the prediction. Performance evaluation of the proposed method is performed using the jackknife test on three low-similarity datasets, i.e., D640, 1189 and 25PDB. By means of this method, the overall accuracies of 97.2%, 96.2%, and 93.3% are achieved on these three datasets, which are higher than those of most existing methods. This suggests that the proposed method could serve as a very cost-effective tool for predicting protein structural class especially for low-similarity datasets.

    The aims of the present study were both to describe anthropometrics and cycling power-velocity characteristics in top-level track sprinters, and to test the hypothesis that these variables would represent interesting predictors of the 200 m track sprint cycling performance. Twelve elite cyclists volunteered to perform a torque-velocity test on a calibrated cycle ergometer, after the measurement of their lean leg volume (LLV) and frontal surface area (A(p)), in order to draw torque- and power-velocity relationships, and to evaluate the maximal power (P(max)), and both the optimal pedalling rate (f(opt)) and torque (T(opt)) at which P (max) is reached. The 200 m performances--i.e. velocity (V200) and pedalling rate (f 200)--were measured during international events (REC) and in the 2002 French Track Cycling Championships (NAT). P(max), f(opt), and T(opt) were respectively 1600 +/- 116 W, 129.8 +/- 4.7 rpm and 118.5 +/- 9.8 N . m. P(max) was strongly correlated with T(opt) (p < 0.001), which was correlated with LLV (p < 0.01). V200 was related to P(max) normalized by A(p) (p < or = 0.05) and also to f(opt) (p < 0.01) for REC and NAT. f 200 (155.2 +/- 3, REC; 149 +/- 4.3, NAT) were significantly higher than f(opt) (p < 0.001). These findings demonstrated that, in this population of world-class track cyclists, the optimization of the ratio between P(max) and A(p) represents a key factor of 200 m performance. Concerning the major role also played by f(opt), it is assumed that, considering high values of f 200, sprinters with a high value of optimal pedalling rate (i.e. lower f200-f(opt) difference) could be theoretically in better conditions to maximize their power output during the race and hence performance.

    2013-02-01

    Full Text Available Interdisciplinary cooperation and collaboration have proven to be desirable yet difficult goals to achieve in social science research. The nuanced differences among the domains, frameworks, assumptions, and methods of the various fields of study that comprise such research often hinder attempts to engage in interdisciplinary dialogue that is both meaningful and productive. We show that demography, economics, political science, and sociology are a few of the fields at the vanguard of the interdisciplinary frontier that emerged following the Second World War. In light of the challenges that these fields (along with the natural sciences face in initiating and sustaining interdisciplinary dialogue, we aim to accomplish several tasks. First, we seek to describe the theoretical and epistemological linkages among the cores of these four social-science disciplines. Second, we explore systems theory as a potential foundation for interdisciplinary unity. Third, we extrapolate the implications of the systems approach to encompass the study of human populations from multiple disciplinary perspectives. In this vein, we also seek to characterize key features of human populations, parse their functions in various disciplinary contexts, and prospectively identify challenges in data interpretation and analysis that will likely emerge in practice. The ultimate goals of this study are to delineate a set of methodological standards with which to guide interdisciplinary inquiry in the social and natural sciences, and consider how we might implement these standards in the construction of a world-historical data archive.

    Full Text Available The study aimed to investigate gender inequalities and their health associated factors in world countries. A cross-sectional survey was undertaken using data of United Nations Development Programme (UNDP and World Health Organization (WHO. The main variable in this study was gender inequality index (GII. All countries were stratified by WHO regions. Pearson correlation coefficient was used to assess the linear correlation between GII and investigated factors by WHO regions. The mean of GII was greater in Africa and lower in Europe region. There was negative significant association between GII and life expectancy at birth and mean years of schooling, prevalence of current tobacco smoking, high blood pressure and overweight and obesity, alcohol consumption rate, and cancer death rate. But there was positive significant association between GII and noncommunicable diseases death rates. In conclusion, gender inequalities, though decreasing over the past decades in world, remain notably greater in Africa and Eastern Mediterranean regions than in Europe. Gender inequality is also an important issue which is related to health factors. Hence, countries will need to focus on public health intervention and equal distribution of economic resources to reduce gender inequality in society.

    Oxidation of pectin was performed with sodium periodate to prepare pectin dialdehyde (PD). In this study we used the cross-linking reaction of the active aldehyde of PD and the amino of carboxymethyl chitosan (CMC) to prepare the hydrogels. By controlling the proportion of pectin dialdehyde and CMC we made different kinds of hydrogels. We systematically studied the characters of the hydrogels using Fourier transform infrared spectroscopy analysis of the pectin dialdehyde, CMC and the hydrogels, and also X-ray diffractometry and scanning electron microscopy analysis of the instrument of the hydrogels. Equilibrium swelling showed that the gels retained about 88-93% water. The water vapor transmission rate (WVTR) and the evaporation of water from gels showed that such hydrogels were optimal for maintaining a moist environment conducive for wound healing. Examination of the hemolytic potential showed that the hydrogels were nonhemolytic in nature. The hydrogels were non-toxic and blood-compatible. This hydrogel prepared from oxidized pectin and CMC without employing any extraneous cross-linking agents is expected to have potential as wound-dressing material.

    2008-01-01

    We construct a new brane-world model composed of a bulk -with a dilatonic field-, plus a brane -with brane tension coupled to the dilaton-, cold dark matter and an induced gravity term. It is possible to show that depending on the nature of the coupling between the brane tension and the dilaton this model can describe the late-time acceleration of the brane expansion (for the normal branch) as it moves within the bulk. The acceleration is produced together with a mimicry of the crossing of the cosmological constant line (w=-1) on the brane, although this crossing of the phantom divide is obtained without invoking any phantom matter neither on the brane nor in the bulk. The role of dark energy is played by the brane tension, which reaches a maximum positive value along the cosmological expansion of the brane. It is precisely at that maximum that the crossing of the phantom divide takes place. We also show that these results remain valid when the induced gravity term on the brane is switched off.

    Asteroids that can intersect the orbit of the earth are discussed, which include Aten asteroids (semimajor axis (a) less than 1 AU, aphelion greater than 0.983 AU), Apollo asteroids (a greater than 1 AU, perihelion less than 1.017 AU), and Amor asteroids (perihelion distance between 1.017 and 1.3 AU). The principal sources of earth-crossing asteroids appear to be extinct comet nuclei and collision fragments from regions in the main asteroid belt. The total population of earth-crossers is estimated at 13,000, of which approximately 8% are Atens, 50% are Apollos, and 40% are Amors,and the present collision rate of such asteroids with the earth is estimated at about 3.5 objects, to absolute magnitude 18, per million years.

    2001-12-01

    The cross-correlation matrix of daily returns of stock market indices in a diverse set of 37 countries worldwide was analyzed. Comparison of the spectrum of this matrix with predictions of random matrix theory provides an empirical evidence of strong interactions between individual economies, as manifested by three largest eigenvalues and the corresponding set of stable, non-random eigenvectors. The observed correlation structure is robust with respect to changes in the time horizon of returns ranging from 1 to 10 trading days, and to replacing individual returns with just their signs. This last observation confirms that it is correlations between signs and not absolute values of fluctuations, which are mostly responsible for the observed effect. Negative changes in the index are somewhat more correlated than the positive ones. Also, in our data set the reaction of Asian stock indices to changes in European and American ones persists for about 3 days.

    We report the results of an investigation of the properties of the networks formed by the cross-correlations of the daily and weekly index changes of 143 stock market indices from 59 different countries. Analysis of the asset graphs, minimum spanning trees (MST) and planar maximally filtered graphs (PMFG) of the afermentioned networks confirms that globalization has been increasing in recent years. North American and European markets are observed to be much more strongly connected among themselves compared to the integration with the other geographical regions. Surprisingly, the integration of East Asian markets among themselves as well as to the Western markets is found to be rather weak. MST and PMFG of both daily and weekly return correlations indicates that the clustering of the indices is mostly geographical. The French fsbf250 index is found to be most important node of the MST and PMFG based on several graph centrality measures.

Musculoskeletal morbidity is the commonest cause for occupational health problems & accounts for large number of workers’ compensation days & disabilities. Aim: To conduct a survey on prevalence of musculoskeletal pain & dysfunction in class 4 female hospital employees Materials & Methodology: Settings & Design: Interview based randomized cross sectional survey. 80 female class 4 employees working at the Lokmanya Tilak municipal medical college & general hospital (LTMMC & LTMGH participated in the study. Based on work pattern, a semi-structured questionnaire was prepared and validated. An informed consent was obtained before the interview. The data thus collected over a period of 3 months was analyzed to determine the prevalence & intensity of musculoskeletal dysfunction, pain & its influence on daily activity. Data was spread in Microsoft Excel 2010 & statistically analyzed using percentages. Results & Conclusion: This study shows that considerable musculoskeletal pain & dysfunction was observed among the women sweepers & aayabai. The back & the knee appear to be affected more than rest of the joints mainly attributed to the combined effect of occupational & psychological stress.

    In the last decade there have been marked reductions in malaria incidence in sub-Saharan Africa. Sustaining these reductions will rely upon insecticides to control the mosquito malaria vectors. We report that in the primary African malaria vector, Anopheles gambiae sensu stricto, a single enzyme, CYP6M2, confers resistance to two classes of insecticide. This is unique evidence in a disease vector of cross-resistance associated with a single metabolic gene that simultaneously reduces the efficacy of two of the four classes of insecticide routinely used for malaria control. The gene-expression profile of a highly DDT-resistant population of A. gambiae s.s. from Ghana was characterized using a unique whole-genome microarray. A number of genes were significantly overexpressed compared with two susceptible West African colonies, including genes from metabolic families previously linked to insecticide resistance. One of the most significantly overexpressed probe groups (false-discovery rate-adjusted P metabolize both type I and type II pyrethroids in recombinant protein assays. Using in vitro assays we show that recombinant CYP6M2 is also capable of metabolizing the organochlorine insecticide DDT in the presence of solubilizing factor sodium cholate.

  7. Soybean exports and deforestation from a world-systems perspective: a cross-national investigation of comparative disadvantage.

    Austin, Kelly F

    2010-01-01

    This article draws on world-system theorizing to explore the relationship between deforestation and the vertical flow of soybean exports from less-developed nations to more-developed nations as a specific form of ecologically unequal exchange. Despite overwhelming case-study research exploring soybean-deforestation dynamics in less-developed countries, the current literature lacks any cross-national investigation of this trend. Ordinary least squares regression is used to examine whether soybean exports are associated with deforestation and if the magnitude of this relationship varies by region. Overall, the findings confirm the proposed hypotheses and suggest that having a comparative advantage in soybean production is not a viable development strategy.

  8. The comings and goings of MHC class I molecules herald a new dawn in cross-presentation.

    Science.gov (United States)

    Blander, J Magarian

    2016-07-01

    MHC class I (MHC-I) molecules are the centerpieces of cross-presentation. They are loaded with peptides derived from exogenous sources and displayed on the plasma membrane to communicate with CD8 T cells, relaying a message of tolerance or attack. The study of cross-presentation has been focused on the relative contributions of the vacuolar versus cytosolic pathways of antigen processing and the location where MHC-I molecules are loaded. While vacuolar processing generates peptides loaded onto vacuolar MHC-I molecules, how and where exogenous peptides generated by the proteasome and transported by TAP meet MHC-I molecules for loading has been a matter of debate. The source and trafficking of MHC-I molecules in dendritic cells have largely been ignored under the expectation that these molecules came from the Endoplasmic reticulum (ER) or the plasma membrane. New studies reveal a concentrated pool of MHC-I molecules in the endocytic recycling compartment (ERC). These pools are rapidly mobilized to phagosomes carrying microbial antigens, and in a signal-dependent manner under the control of Toll-like receptors. The phagosome becomes a dynamic hub receiving traffic from multiple sources, the ER-Golgi intermediate compartment for delivering the peptide-loading machinery and the ERC for deploying MHC-I molecules that alert CD8 T cells of infection.

  9. Modern Attitudes Toward Older Adults in the Aging World: A Cross-Cultural Meta-Analysis.

    North, Michael S; Fiske, Susan T

    2015-09-01

    Prevailing beliefs suggest that Eastern cultures hold older adults in higher esteem than Western cultures do, due to stronger collectivist traditions of filial piety. However, in modern, industrialized societies, the strain presented by dramatic rises in population aging potentially threatens traditional cultural expectations. Addressing these competing hypotheses, a literature search located 37 eligible papers, comprising samples from 23 countries and 21,093 total participants, directly comparing Easterners and Westerners (as classified per U.N. conventions) in their attitudes toward aging and the aged. Contradicting conventional wisdom, a random-effects meta-analysis on these articles found such evaluations to be more negative in the East overall (standardized mean difference = -0.31). High heterogeneity in study comparisons suggested the presence of moderators; indeed, geographical region emerged as a significant moderating factor, with the strongest levels of senior derogation emerging in East Asia (compared with South and Southeast Asia) and non-Anglophone Europe (compared with North American and Anglophone Western regions). At the country level, multiple-moderator meta-regression analysis confirmed recent rises in population aging to significantly predict negative elder attitudes, controlling for industrialization per se over the same time period. Unexpectedly, these analyses also found that cultural individualism significantly predicted relative positivity-suggesting that, for generating elder respect within rapidly aging societies, collectivist traditions may backfire. The findings suggest the importance of demographic challenges in shaping modern attitudes toward elders-presenting considerations for future research in ageism, cross-cultural psychology, and even economic development, as societies across the globe accommodate unprecedented numbers of older citizens.

  10. A lovely war: male to female cross-dressing and Canadian military entertainment in World War II.

    Science.gov (United States)

    Halladay, Laurel

    2004-01-01

    This article explores the Canadian military entertainment units during World War II (WWII), specifically those formed by the Navy, Army and Air Force from talent found amongst their own personnel. These entertainment units toured extensively in Canada, the United Kingdom and Europe with the goal of increasing the morale of combat troops while encouraging the enlistment of Canada's domestic populations in the war effort generally and the armed forces specifically. By focusing on male to female cross-dressing in the performances of these entertainment units and their pre-WWII antecedents, it will become clear that the nature and importance of the representation of femininity within the virtually all-male milieu that existed near the battlefront changed over time in response to the demands of the audiences. Until the second half of WWII, soldier audiences were generally unwilling to form any ideological links between cross-dressing and homosexuality. Female impersonators were the key cast members in troop shows during the Great War, but eventually fell out of favor in the last years of WWII after women were recruited in large numbers into the Canadian military and thus its entertainment infrastructure. With women then on the military stage, men who persisted in female impersonation were decreasingly popular with audiences, ultimately under growing suspicion of being homosexuals and gradually removed from the productions.

    Newer oral antidiabetic drug classes are expanding treatment options for type 2 diabetes mellitus (T2DM); however, concerns remain. The objective was to assess relative risk of heart failure hospitalization of sodium-glucose co-transporter-2 (SGLT2) and dipeptidyl peptidase-4 (DPP4) inhibitors in T2DM patients. This retrospective observational study used a national commercially insured claims database. Adults (>18 years) with T2DM newly starting SGLT2 or DPP4 medication between April 2013 and December 2014 were included. Depending on their index fill, patients were grouped into either SGLT2 or DPP4 medication class cohorts. The primary outcome was hospitalization for heart failure and the risk was assessed using Cox regression models. Propensity score matching (1:2 ratio) was used to adjust for potential confounders. Analyses were also stratified by the presence of baseline diabetes complication and age (heart failure hospitalization was lower among SGLT2 users in comparison with matched DPP4 users (2.0% SGLT2 vs 3.1% DPP4; adjusted hazard ratio [aHR] 0.68; 95% confidence interval [CI] 0.54-0.86; p = .001). However, the stratified analyses revealed no risk difference among the majority of the analyzed patients, i.e., those aged heart failure was significantly lower for patients initiating an SGLT2 compared with a DPP4 medication, specifically among older patients and those with diabetes complication.

    A body of academic research has shown a social class gradient in psychological well-being. Some recent work has also suggested that the gradient is worsening over time, though the evidence is mixed. We focus on two straightforward research questions: Is there a class gradient in mental health? Has this gradient changed over time? We answer these questions with attention to two specific causal pathways: employment status and unobserved heterogeneity. We use two data sources: repeated cross-sections from the Health Survey of England (HSE) and longitudinal data from the British Household Panel Survey (BHPS). The combination of pooled OLS regression (with HSE) and fixed effects analysis (with BHPS) allows for a robust analysis of the relationship between class and psychological well-being. We argue that employment status is a confounder in the analysis of class inequalities and show that, along with unobserved heterogeneity, these two pathways go a long way to explain the class gradient. The effects of employment status are substantive and, unlike social class, cannot be explained away by unobserved heterogeneity. We conclude that employment status deserves greater prominence in the debate as both a pathway by which the class gradient transpires, and as another 'dimension' of inequality in its own right. Our overtime analysis suggests that skilled and unskilled manual workers had higher psychological well-being in the 1990s but by 2008 were closer to the average. Class inequalities do not appear to be widening.

  2. The left hand second to fourth digit ratio (2D:4D does not discriminate world-class female gymnasts from age matched sedentary girls.

    Directory of Open Access Journals (Sweden)

    Maarten W Peeters

    Full Text Available INTRODUCTION: The second to fourth-digit-ratio (2D:4D, a putative marker of prenatal androgen action and a sexually dimorphic trait, has been suggested to be related with sports performance, although results are not univocal. If this relation exists, it is most likely to be detected by comparing extreme groups on the continuum of sports performance. METHODS: In this study the 2D:4D ratio of world-class elite female artistic gymnasts (n = 129, competing at the 1987 Rotterdam World-Championships was compared to the 2D:4D ratio of sedentary age-matched sedentary girls (n = 129, alongside with other anthropometric characteristics including other sexually dimorphic traits such as an androgyny index (Bayer & Bayley and Heath-Carter somatotype components (endomorphy, mesomorphy, ectomorphy using AN(COVA. 2D:4D was measured on X-rays of the left hand. RESULTS: Left hand 2D:4D digit ratio in world class elite female gymnasts (0.921±0.020 did not differ significantly from 2D:4D in age-matched sedentary girls (0.924±0.018, either with or without inclusion of potentially confounding covariates such as skeletal age, height, weight, somatotype components or androgyny index. Height (161.9±6.4 cm vs 155.4±6.6 cm p0.01, somatotype components (4.0/3.0/2.9 vs 1.7/3.7/3.2 for endomorphy (p<0.01, mesomorphy (p<0.01 and ectomorphy (p<0.05 respectively all differed significantly between sedentary girls and elite gymnasts. As expressed by the androgyny index, gymnasts have, on average, broader shoulders relative to their hips, compared to the reference sample. Correlations between the 2D:4D ratio and chronological age, skeletal age, and the anthropometric characteristics are low and not significant. CONCLUSION: Although other anthropometric characteristics of sexual dimorphism were significantly different between the two samples, the present study cannot discriminate sedentary girls from world-class female gymnasts by means of the left hand 2D:4D ratio.

    Full Text Available The physiological consequences of ultra-endurance cross-country skiing in cold conditions are poorly known. We report here clinical, echocardiographic and laboratory findings from a 41-y old male elite skier in a world record trial for 24-h skiing. The athlete completed a total of 406.8 km outdoors with the temperature ranging between -24°C and –5°C during the 24-h period. Post exercise, notable increases from baseline values were observed in myoglobin (50-fold, creatinine kinase (30-fold and proBNP (6-fold, whereas troponin T or troponin I levels remained unchanged. At baseline, echocardiographic findings showed cardiac hypertrophy and after skiing, a 5% reduction of left-ventricular end-diastolic dimension. Increases in markers of kidney (creatinine and liver function (alanine aminotransferase, serum uric acid, C-reactive protein and white blood cell counts were also noted. In addition, electrolyte disturbances including hyponatremia, hypophosphatemia and hypocalcaemia were noted during the follow-up. The data indicates that a prolonged period of high-intensity skiing leads to muscle, heart and kidney affection and activation of inflammation even in an experienced elite skier. The observed health effects underscore the need for strict medical surveillance of participants in extreme sports with long duration.

    Full Text Available BACKGROUND: While mass media communications can be an important source of health information, there are substantial social disparities in health knowledge that may be related to media use. The purpose of this study is to investigate how the use of cancer-related health communications is patterned by race, ethnicity, language, and social class. METHODOLOGY/PRINCIPAL FINDINGS: In a nationally-representative cross-sectional telephone survey, 5,187 U.S. adults provided information about demographic characteristics, cancer information seeking, and attention to and trust in health information from television, radio, newspaper, magazines, and the Internet. Cancer information seeking was lowest among Spanish-speaking Hispanics (odds ratio: 0.42; 95% confidence interval: 0.28-0.63 compared to non-Hispanic whites. Spanish-speaking Hispanics were more likely than non-Hispanic whites to pay attention to (odds ratio: 3.10; 95% confidence interval: 2.07-4.66 and trust (odds ratio: 2.61; 95% confidence interval: 1.53-4.47 health messages from the radio.

    To determine epidemiology of cardiovascular risk factors according to geographic distribution and macrolevel social development index among urban middle class subjects in India. We performed cross-sectional surveys in 11 cities in India during years 2005-2009. 6198 subjects aged 20-75 years (men 3426, women 2772, response 62%) were evaluated for cardiovascular risk factors. Cities were grouped according to geographic distribution into northern (3 cities, n = 1321), western (2 cities, n = 1814), southern (3 cities, n = 1237) and eastern (3 cities, n = 1826). They were also grouped according to human social development index into low (3 cities, n = 1794), middle (5 cities, n = 2634) and high (3 cities, n = 1825). Standard definitions were used to determine risk factors. Differences in risk factors were evaluated using χ(2) test. Trends were examined by least squares regression. Age-adjusted prevalence (95% confidence intervals) of various risk factors was: low physical activity 42.1% (40.9-43.3), high dietary fat 49.9% (47.8-52.0), low fruit/vegetables 26.9% (25.8-28.0), smoking 10.1% (9.1-11.1), smokeless tobacco use 9.8% (9.1-10.5), overweight 42.9% (41.7-44.1), obesity 11.6% (10.8-12.4), high waist circumference 45.5% (44.3-46.7), high waist-hip ratio 75.7% (74.7-76.8), hypertension 31.6% (30.4-32.8), hypercholesterolemia 25.0% (23.9-26.9), low HDL cholesterol 42.5% (41.3-43.7), hypertriglyceridemia 36.9% (35.7-38.1), diabetes 15.7% (14.8-16.6), and metabolic syndrome 35.7% (34.5-36.9).

    Full Text Available One of the most important prerequisites for economic competitiveness in the global economy, is the delivery of a unique product or service. In order to achieve this level of competitiveness, transformational rather than transactional leadership should be a core element in organisation’s ascent to ‘world-class’ status. Inline with other researching results, the most important finding of this study, which was conducted in a petrochemical industry, is that transformational leadership is not up to standard.

The data indicates that a prolonged period of high-intensity skiing leads to muscle, heart and kidney affection and activation of inflammation even in an experienced elite skier. The observed health effects underscore the need for strict medical surveillance of participants in extreme sports with long duration. Key pointsAn elite athlete was able to ski over 400 km during 24 hours with an outdoor temperature ranging between -5 °C and -24 °C.Several postrace abnormalities occurred in biomarkers of muscle, heart, kidney, liver and inflammation status.Serum troponins, specific markers of myocardial cell damage, remained stable.The report supports careful medical surveillance of participants in extreme sports with long duration.

    The lithosphere structure and deep processes are keys to understanding mineral system and ore-forming processes. Lithosphere-scale process could create big footprints or signatures which can be observed by geophysics methods. SinoProbe-03 has conducted a Transect exploration across middle and lower Yangtze Metallogenic Belt (YMT) in Eastern China. Broadband seismic, reflection seismic, wide-angle reflection and magnetotellurics survey were carried out along the Transect. Seismic reflection profiles and MT survey were also performed in Luzong, Tongling and Ningwu ore districts to construct 3D geological model. The resulting geophysical data provides new information which help to better understanding the lithosphere structure, deep processes and deformation history of the Metallogenic Belt. The major results are: (1) Lower velocity body at the top of upper mantle and a SE dipping high velocity body were imaged by teleseismic tomography beneath YMB; (2) Shear wave splitting results show NE parallel fast-wave polarization direction which parallel with tectonic lineament; (3) The reflection seismic data support the crustal-detachment model, the lower and upper crust was detached during contraction deformation near Tanlu fault and Ningwu volcanic basin; (4) Broadband and reflection seismic confirm the shallow Moho beneath YMB; (5) Strong correlation of lower crust reflectivity with magmatism. All these features suggest that introcontinental subduction, lithosphere delamination, mantle sources magmatic underplating, and MASH process are responsible for the formation of wild-class metallogenic belt.

    Iliac blood-flow restrictions causing painful and "powerless" legs are often attributed to overtraining and may develop for some time before being correctly diagnosed. In the current study, differences between actual performance parameters and performance parameters predicted from the Lamberts and Lambert Submaximal Cycle Test (LSCT) were studied in a world-class cyclist with bilateral kinking of the external iliac artery before and after surgery. Two performance-testing sessions, including a peak-power-output (PPO) test and a 40-km time trial (TT) were conducted before surgery, while 1 testing session was conducted after the surgery. Actual vs LSCT-predicted performance parameters in the world-class cyclists were compared with 82 symptom-free trained to elite male cyclists. No differences were found between actual and LSCT-predicted PPO before and after surgical intervention. However, there were differences between actual and LSCT-predicted 40-km TT time in the tests performed before the surgery (2:51and 2:55 min:s, respectively). These differences were no longer apparent in the postsurgery 40-km TT (2 s). This finding suggests that iliac blood-flow restrictions seem to mainly impair endurance performance rather than peak cycling performance. A standard PPO test without brachial ankle blood-pressure measurements might not be able to reflect iliac blood-flow restrictions. Differences between actual and LSCT-predicted 40-km TT time may assist in earlier referral to a cardiovascular specialist and result in earlier detection of iliac blood-flow restrictions.

    To examine the blood metabolic responses of world-class boxers involved in international competition (Test match), 33 male boxers (mean ± SD) competing internationally across all the official weight categories were studied on 2 different occasions: Test match 1 (team A against team B) and Test match 2 (team A against team C). Blood samples were collected after the third round for both Test matches for all teams except team B. For all Test matches and boxers, mean blood lactate concentration ([BLac]), bicarbonate concentration, hemoglobin O2 saturation (SaO2), partial pressure for CO2 (PCO2), and pH were 13.6 ± 2.4 mmol·L(-1), 13.2 ± 2.3 mmol·L(-1), 95.0 ± 2.6%, 32.0 ± 5.5 mm Hg, and 7.22 ± 0.06 with 7/20 final pH values <7.20. The intermediate category (60-64 kg) was characterized by the greatest [BLac] (14.8 ± 2.9) compared with the heaviest and lighter boxers (∼12 mmol·L(-1)). During the second match (team A again team C), a significant difference between pH, PCO2, and SaO2 values was observed with no concomitant difference in [BLac] suggesting a better buffering capacity in team A. This result highlights the need for a well-developed anaerobic and buffering capacity and indicates that world-class boxers must be able to tolerate a substantial level of acidosis to produce high levels of boxing activity until the end of a match.

    the students in a sophomore level course demonstrated that the use of the game positively enhanced student engagement and interest in the course. We adapted the same base concepts to a real-world setting where players must physically collect water from a contaminated surface water source, represented by a swimming pool where many players can access the resource simultaneously, and a clean groundwater source, represented by a barrel where only one player at a time can obtain water from a pump. Additionally, water is recharged to groundwater (i.e., the barrel) at a fixed rate, thus over pumping can cause the water table to drop and cause the well to go dry. Players must therefore grapple between health risks associated with contaminants and the mass balance problems caused by groundwater mining. This version of the game received positive reviews from girls in grades 6-9 participating in a STEM summer camp.

  19. Critiques of World-Systems Analysis and Alternatives: Unequal Exchange and Three Forms of Class and Struggle in the Japan–US Silk Network, 1880–1890

    2015-08-01

    Full Text Available Sympathetic critics of world-system analysis contend that its systemic level of abstraction results in one-sided generalizations of systemic change. Unequal exchange theory and commodity chain analysis similarly reduce distinct and historical forms of labor and their interrelationships to common functional and ahistorical essences. This paper applies an incorporated comparisons method to give historical content to an understanding of unequal exchange and global inequality through a study of the Japan–US silk network’s formation and change during the mid 1880–1890s. Analysis of unequal exchange processes requires, in this case, an examination of the mutual integration and transformation of distinct labor and value forms —peasant sericulture, ?lature wage-labor, and industrial silk factory wage-labor—and the infundibular market forces they structured. These relations were decisively conditioned by new landlordism and debt-peonage, class-patriarchy, state mediations, migration, and by peasant and worker struggles against deteriorating conditions. Indeed, the transitional nature of the silk network’s formation, which concluded the Tokugawa system and decisively contributed to Japan’s emergence as a nation-state of the capitalist world-economy, was signi?ed by the very last millenarian and quasi-modern peasant uprising in 1884 among indebted sericulturists, the very ?rst recorded factory strikes in 1885–86, by women raw silk reelers in K?fu, and by strikes among unionizing workers in patriarchal and mechanized silk factories in Paterson, New Jersey, 1885–86 (Boles 1996, 1998. The “local” conditions of each con?ict were molded by the interdependence of those conditions that constituted a formative part of the world-system and its development. In the face of struggles and intensifying world-market competition, Japanese and US manufacturers took opposite spatial strategies of regional expansion to overcome the structural constraints of

    The purpose of this cross-sectional study was to assess the sociodemographics, disease burden, and treatment patterns of patients with episodic and chronic migraine in the United States. Migraine is a disabling neurological disease that places an enormous burden on patients. Data were drawn from the Adelphi Migraine United States Disease Specific Programme (index period: January to March 2014). Physicians (N = 150) completed a patient report form on 10 consulting patients with migraine. Episodic migraineurs had ≤14 headache days per month (HDM) and those with chronic migraine had ≥15. Headache-related disability was assessed with the Migraine Disability Assessment (MIDAS) questionnaire. Disability was also compared across subgroups based on the number of HDM (≤3, 4-7, 8-14, and ≥15). A total of 1487 patient report forms were completed. Over 70% of the patients were female, 90.8% (n = 1350) were episodic migraineurs, and 9.2% (n = 137) were chronic migraineurs. Acute treatment was prescribed for >90% of the patients, and >50% had a current prescription for preventive treatment. Despite taking acute and/or preventive treatment, 29.2% of episodic migraineurs (including some patients with ≤3 headache days/month) and 73.2% of chronic migraineurs had moderate-to-severe headache-related disability (MIDAS total score ≥11). Preventive treatment was discontinued/switched at least once by 26.4% of episodic migraineurs and by 53.3% of chronic migraineurs. Of those patients (n = 382) who gave collective reasons for discontinuation/switching preventive treatment, over 70% selected lack of efficacy and tolerability/safety. This real-world analysis provides additional support for the unmet medical need for efficacious therapies that reduce migraine frequency and severity, headache-related disability, and have better tolerability for patients with migraine. In addition, further research is needed to better understand the burden of illness among patients

Periodic delimitation was in the year of 1917, when it occurs the spreading of Brazil’s participation in 1st World War and 1918 the spreading of the departure of a Brazilian medical commission for attendance to the wounded in the War. Documental study grounded in Bordieu conceptual frame, based on written and photographic documents refereeing that time, and with a special detach to the analysis of four pictures published in The Week Magazine. The I World War agitated the written and illustrated press. The Brazilian Red Cross, through the School of Nurses of São Paulo, presented to the society the nurses technical competences for aid care assistance with the habitus formation and school status acquired, but because adverse reasons it did not get real visibility in the institutional report. But, in the illustrated press we find vestiges of the Brazilian nurses participation in a hospital in Paris.

    This study tested a novel explanation for the positive relation between social class and mental health among university students. Students with a higher social class were expected to have experienced more authoritative and less authoritarian parenting styles; these parenting styles were expected to lead to greater friendship and social integration at university; and greater friendship and integration were expected to lead to better mental health. To test this model, the researchers asked 397 Australian undergraduate students to complete an online survey. The research used a cross-sectional correlational design, and the data was analysed using bootstrapped multiple serial mediation tests. Consistent with predictions, parenting style, general friendship and support, and social integration at university mediated the relation between social class and mental health. The present results suggest that working-class parenting styles may inhibit the development of socially-supportive friendships that protect against mental health problems. The potential effectiveness of interventions based on (a) social integration and (b) parenting style is discussed. Future research in this area should employ a longitudinal research design in order to arrive at clearer causal conclusions about the relations between social class, parenting styles, friendship, social integration, and mental health.

    The National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) is leading the design and build of the new world-class vibroacoustic test capabilities at the NASA GRC's Plum Brook Station in Sandusky, Ohio, USA. Benham Companies, LLC is currently constructing modal, base-shake sine and reverberant acoustic test facilities to support the future testing needs of NASA's space exploration program. The large Reverberant Acoustic Test Facility (RATF) will be approximately 101,000 cu ft in volume and capable of achieving an empty chamber acoustic overall sound pressure level (OASPL) of 163 dB. This combination of size and acoustic power is unprecedented amongst the world's known active reverberant acoustic test facilities. The key to achieving the expected acoustic test spectra for a range of many NASA space flight environments in the RATF is the knowledge gained from a series of ground acoustic tests. Data was obtained from several NASA-sponsored test programs, including testing performed at the National Research Council of Canada's acoustic test facility in Ottawa, Ontario, Canada, and at the Redstone Technical Test Center acoustic test facility in Huntsville, Alabama, USA. The majority of these tests were performed to characterize the acoustic performance of the modulators (noise generators) and representative horns that would be required to meet the desired spectra, as well as to evaluate possible supplemental gas jet noise sources. The knowledge obtained in each of these test programs enabled the design of the RATF sound generation system to confidently advance to its final acoustic design and subsequent on-going construction.

  7. MHC class I-presented T cell epitopes identified by immunoproteomics analysis are targets for a cross reactive influenza-specific T cell response.

    Directory of Open Access Journals (Sweden)

    James S Testa

    Full Text Available Influenza virus infection and the resulting complications are a significant global public health problem. Improving humoral immunity to influenza is the target of current conventional influenza vaccines, however, these are generally not cross-protective. On the contrary, cell-mediated immunity generated by primary influenza infection provides substantial protection against serologically distinct viruses due to recognition of cross-reactive T cell epitopes, often from internal viral proteins conserved between viral subtypes. Efforts are underway to develop a universal flu vaccine that would stimulate both the humoral and cellular immune responses leading to long-lived memory. Such a universal vaccine should target conserved influenza virus antibody and T cell epitopes that do not vary from strain to strain. In the last decade, immunoproteomics, or the direct identification of HLA class I presented epitopes, has emerged as an alternative to the motif prediction method for the identification of T cell epitopes. In this study, we used this method to uncover several cross-specific MHC class I specific T cell epitopes naturally presented by influenza A-infected cells. These conserved T cell epitopes, when combined with a cross-reactive antibody epitope from the ectodomain of influenza M2, generate cross-strain specific cell mediated and humoral immunity. Overall, we have demonstrated that conserved epitope-specific CTLs could recognize multiple influenza strain infected target cells and, when combined with a universal antibody epitope, could generate virus specific humoral and T cell responses, a step toward a universal vaccine concept. These epitopes also have potential as new tools to characterize T cell immunity in influenza infection, and may serve as part of a universal vaccine candidate complementary to current vaccines.

    To investigate separate and combined associations of occupational social class and personality traits with late midlife leisure-time physical activity duration and intensity. Cross-sectional data from the Copenhagen Aging and Midlife Biobank ( N = 4,649) were analyzed using linear regression models with leisure-time physical activity (metric equivalence) as outcome. Low versus high occupational social class was associated with 4% (95% confidence interval [CI] = [3%, 5%]) greater leisure-time physical activity duration, but 2% (CI = [1%, 3%]) lower intensity. Each 10-unit increase in extraversion was associated with 5% (CI = [2%, 8%]) greater duration. Intensity increased by each 10-unit increase in conscientiousness (6%, CI = [4%, 7%]), openness (3%, CI = [1%, 4%]), neuroticism (3%, CI = [1%, 4%]), and extraversion (5%, CI = [4%, 7%]). Conscientiousness was positively associated with duration in low, but not in high, occupational social class (interaction p value = .002). Higher occupational social class was associated with lower leisure-time physical activity duration, but higher intensity. Extraversion was positively associated with duration and intensity. Conscientiousness, openness, and neuroticism were positively associated with intensity. Overall, interactions were not consistent.

    The prevalence of antibodies to human platelet antigens (HPA) and human leukocyte antigens (HLA) class 1 antigens among Nigerian pregnant women has not been reported in our country. This study was therefore aimed at screening the obstetric population for evidence of alloimmunization due to human platelet and HLA class 1 antigens. One hundred and forty four (144) pregnant women attending the obstetric clinic of Military Hospital, Port Harcourt, participated in the study. Their sera were tested for antibodies to HPA and HLA class 1 antigens using GTI PakPlus solid phase ELISA Kit. The total prevalence rate of antibody production was 60.5% (87 out of 144). Among the positive samples, 60 had platelet glycoprotein specific antibodies (41.7%) and 27 had HLA class 1 antibodies (18.8%). In 39.6% of the pregnant women, both platelet specific antibodies and HLA class 1 antibodies appeared. The prevalence of platelet specific glycoprotein antibodies were obtained as follows: GP 11b/111a 12 (8.3%), GP 1a/11a 35 (20.8%), GP Ib/IX 18 (12.5%) and GP IV 9 (6.3%). The prevalence of each platelet antibody subgroup was obtained as follows: anti-HPA-1a,-3a,-4a (4.2%), anti-HPA-1b,-3b,-4a (4.2%), anti-HPA-30 5a and anti-GP Ib/IX (12.5% each), anti-HPA-5b (8.3%) and anti-GP IV (6.3%). A high prevalence rate of human platelet arid cytotoxic antibodies has been observed in our obstetric population. There is need to establish platelet serology laboratory for the proper antenatal and postnatal management of pregnant mothers in this region.

    The development of versatile vaccine platforms is a priority that is recognized by health authorities worldwide; such platforms should induce both arms of the immune system, the humoral and cytotoxic-T-lymphocyte responses. In this study, we have established that a vaccine platform based on the coat protein of papaya mosaic virus (PapMV CP), previously shown to induce a humoral response, can induce major histocompatibility complex (MHC) class I cross-presentation of HLA-A*0201 epitopes from gp100, a melanoma antigen, and from influenza virus M1 matrix protein. PapMV proteins were able to assemble into stable virus-like particles (VLPs) in a crystalline and repetitive structure. When we pulsed HLA-A*0201+ antigen-presenting cells (APCs) with the recombinant PapMV FLU or gp100, we noted that antigen-specific CD8+ T cells were highly reactive to these APCs, demonstrating that the epitope from the VLPs were processed and loaded on the MHC class I complex. APCs were preincubated with two different proteasome inhibitors, which did not affect the efficiency of peptide presentation on MHC class I. Classical presentation from an endogenous antigen was abolished in the same conditions. Clearly, antigen presentation mediated by the PapMV system was proteasome independent. Finally, PapMV-pulsed APCs had the capacity to expand highly avid antigen-specific T cells against the influenza virus M1 HLA-A*0201 epitope when cocultured with autologous peripheral blood mononuclear cells. This study demonstrates the potential of PapMV for MHC class I cross-presentation and for the expansion of human antigen-specific T cells. It makes VLPs from PapMV CP a very attractive platform to trigger cellular responses for vaccine development against chronic infectious diseases and cancers.

    Full Text Available BACKGROUND: In the months leading up to the 2010 FIFA World Cup in South Africa, international media postulated that at least 40,000 foreign sex workers would enter South Africa, and that an increased HIV incidence would follow. To strengthen the evidence base of future HIV prevention and sexual health programmes during international sporting events, we monitored the supply and demand of female sex work in the weeks before, during and after the 2010 FIFA World Cup. METHODOLOGY/PRINCIPAL FINDINGS: We conducted three telephonic surveys of female sex workers advertising online and in local newspapers, in the last week of May, June and July 2010. The overall response rate was 73.4% (718/978. The number of sex workers advertising online was 5.9% higher during the World Cup than before. The client turnover rate did not change significantly during (adjusted rate ratio [aRR] = 1.05; 95%CI: 0.90-1.23 or after (aRR = 1.06; 95%CI: 0.91-1.24 the World Cup. The fraction of non-South African sex workers declined during (adjusted odds ratio [aOR] = 0.50; 95%CI: 0.32-0.79 and after (aOR = 0.56; 95%CI: 0.37-0.86 the World Cup. Relatively more clients were foreign during the World Cup among sex workers advertising in the newspapers (aOR = 2.74; 95%CI: 1.37-5.48 but not among those advertising online (aOR = 1.06; 95%CI: 0.60-1.90. Self-reported condom use was high (99.0% at baseline, and did not change during (aOR = 1.07; 95% CI: 0.16-7.30 or after (aOR = 1.13; 95% CI: 0.16-8.10 the Word Cup. CONCLUSIONS/SIGNIFICANCE: Our findings do not provide evidence for mass-immigration of foreign sex workers advertising online and in local newspapers, nor a spike in sex work or risk of HIV transmission in this subpopulation of sex workers during the World Cup. Public health programmes focusing on sex work and HIV prevention during international sporting events should be based on evidence, not media-driven sensationalism that further heightens

    Physical and mental changes associated with aging commonly lead to a decrease in communication capacity, reducing social interactions and increasing loneliness. Computer classes for older adults make significant contributions to social and cognitive aspects of aging. Games in a virtual reality (VR) environment stimulate the practice of communicative and cognitive skills and might also bring benefits to older adults. Furthermore, it might help to initiate their contact to the modern technology. The purpose of this study protocol is to evaluate the effects of practicing VR games during computer classes on the level of loneliness of students of an elderly reference center. This study will be a prospective longitudinal study with a randomised cross-over design, with subjects aged 50 years and older, of both genders, spontaneously enrolled in computer classes for beginners. Data collection will be done in 3 moments: moment 0 (T0) - at baseline; moment 1 (T1) - after 8 typical computer classes; and moment 2 (T2) - after 8 computer classes which include 15 minutes for practicing games in VR environment. A characterization questionnaire, the short version of the Short Social and Emotional Loneliness Scale for Adults (SELSA-S) and 3 games with VR (Random, MoviLetrando, and Reaction Time) will be used. For the intervention phase 4 other games will be used: Coincident Timing, Motor Skill Analyser, Labyrinth, and Fitts. The statistical analysis will compare the evolution in loneliness perception, performance, and reaction time during the practice of the games between the 3 moments of data collection. Performance and reaction time during the practice of the games will also be correlated to the loneliness perception. The protocol is approved by the host institution's ethics committee under the number 52305215.3.0000.0082. Results will be disseminated via peer-reviewed journal articles and conferences. This clinical trial is registered at ClinicalTrials.gov identifier: NCT

    Multimorbidity defined as the "the coexistence of two or more chronic diseases" in one individual, is increasing in prevalence globally. The aim of this study is to compare the prevalence of multimorbidity across low and middle-income countries (LMICs), and to investigate patterns by age and education, as a proxy for socio-economic status (SES). Chronic disease data from 28 countries of the World Health Survey (2003) were extracted and inter-country socio-economic differences were examined by gross domestic product (GDP). Regression analyses were applied to examine associations of education with multimorbidity by region adjusted for age and sex distributions. The mean world standardized multimorbidity prevalence for LMICs was 7.8 % (95 % CI, 7.79 % - 7.83 %). In all countries, multimorbidity increased significantly with age. A positive but non-linear relationship was found between country GDP and multimorbidity prevalence. Trend analyses of multimorbidity by education suggest that there are intergenerational differences, with a more inverse education gradient for younger adults compared to older adults. Higher education was significantly associated with a decreased risk of multimorbidity in the all-region analyses. Multimorbidity is a global phenomenon, not just affecting older adults in HICs. Policy makers worldwide need to address these health inequalities, and support the complex service needs of a growing multimorbid population.

    2016-11-01

    This paper examines consumers' knowledge and lifestyle profiles and preferences regarding two environmentally labeled food staples, potatoes and ground beef. Data from online choice experiments conducted in Canada and Germany are analyzed through latent class choice modeling to identify the influence of consumer knowledge (subjective and objective knowledge as well as usage experience) on environmentally sustainable choices. We find that irrespective of product or country under investigation, high subjective and objective knowledge levels drive environmentally sustainable food choices. Subjective knowledge was found to be more important in this context. Usage experience had relatively little impact on environmentally sustainable choices. Our results suggest that about 20% of consumers in both countries are ready to adopt footprint labels in their food choices. Another 10-20% could be targeted by enhancing subjective knowledge, for example through targeted marketing campaigns.

    We present the first study of the volcanic rocks of the Cañadón Asfalto Formation that host the Navidad world-class Ag + Pb epithermal district located in the North Patagonian Massif, Patagonia, Argentina. These volcanic and sedimentary rocks were deposited in a lacustrine environment during an extensional tectonic regime associated with the breakup of Gondwana and represent the mafic to intermediate counterparts of the mainly silicic Jurassic Chon Aike Volcanic Province. Lava flows surrounded by autobrecciated carapace were extruded in subaerial conditions, whereas hyaloclastite and peperite facies suggest contemporaneous subaqueous volcanism and sedimentation. LA-ICPMS Usbnd Pb ages of zircon crystals from the volcanic units yielded Middle Jurassic ages of 173.9 ± 1.9 Ma and 170.8 ± 3 Ma. In the Navidad district, volcanic rocks of the Cañadón Asfalto Formation show arc-like signatures including high-K basaltic-andesite to high-K dacite compositions, Rb, Ba and Th enrichment relative to the less mobile HFS elements (Nb, Ta), enrichment in light rare earth elements (LREE), Ysbnd Ti depletion, and high Zr contents. These characteristics could be explained by assimilation of crustal rocks in the Jurassic magmas, which is also supported by the presence of zircon xenocrysts with Permian and Middle-Upper Triassic ages (281.3 Ma, 246.5, 218.1, and 201.3 Ma) and quartz xenocrysts recognized in these volcanic units. Furthermore, Sr and Nd isotope compositions suggest a contribution of crustal components in these Middle Jurassic magmas. High-K basaltic andesite has initial 87Sr/86Sr ratios of 0.70416-0.70658 and ξNd(t) values of -5.3 and -4. High-K dacite and andesite have initial 87Sr/86Sr compositions of 0.70584-0.70601 and ξNd(t) values of -4,1 and -3,2. The range of Pb isotope values (206Pb/204Pb = 18.28-18.37, 207Pb/204Pb = 15.61-15.62, and 208Pb/204Pb = 38.26-38.43) of Navidad volcanic rocks and ore minerals suggest mixing Pb sources with contributions of

    Civic participation, that which directly influences important decisions in our personal lives, is considered necessary for developing a society. We hypothesized that civic participation might be related to self-rated health status. We constructed a multi-level analysis using data from the World Value Survey (44 countries, n=50 859). People who participated in voting and voluntary social activities tended to report better subjective health than those who did not vote or participate in social activities, after controlling for socio-demographic factors at the individual level. A negative association with unconventional political activity and subjective health was found, but this effect disappeared in a subset analysis of only the 18 Organization for Economic Cooperation and Development (OECD) countries. Moreover, social participation and unconventional political participation had a statistically significant contextual association with subjective health status, but this relationship was not consistent throughout the analysis. In the analysis of the 44 countries, social participation was of borderline significance, while in the subset analysis of the OECD countries unconventional political participation was a stronger determinant of subjective health. The democratic index was a significant factor in determining self-rated health in both analyses, while public health expenditure was a significant factor in only the subset analysis. Despite the uncertainty of its mechanism, civic participation might be a significant determinant of the health status of a country.

  8. Involvement of a Novel Class C Beta-Lactamase in the Transglutaminase Mediated Cross-Linking Cascade of Streptomyces mobaraensis DSM 40847.

    Stephan Zindel

    Full Text Available Streptomyces mobaraensis DSM 40847 secretes transglutaminase that cross-links proteins via γ-glutamyl-ε-lysine isopeptide bonds. Characterized substrates are inhibitory proteins acting against various serine, cysteine and metalloproteases. In the present study, the bacterial secretome was examined to uncover additional transglutaminase substrates. Fractional ethanol precipitation of the exported proteins at various times of culture growth, electrophoresis of the precipitated proteins, and sequencing of a 39 kDa protein by mass spectrometry revealed the novel beta-lactamase Sml-1. As indicated by biotinylated probes, Sml-1, produced in E. coli, exhibits glutamine and lysine residues accessible for transglutaminase. The chromogenic cephalosporin analogue, nitrocefin, was hydrolyzed by Sml-1 with low velocity. The obtained Km and kcat values of the recombinant enzyme were 94.3±1.8 μM and 0.39±0.03 s(-1, respectively. Penicillin G and ampicillin proved to be weak inhibitors of nitrocefin hydrolysis (Ki of 0.1 mM and 0.18 mM. Negligible influence of metals on β-lactamase activity ruled out that Sml-1 is a Zn2+-dependent class B beta-lactamase. Rather, sequence motifs such as SITK, YSN, and HDG forming the active core in a hypothetical structure may be typical for class C beta-lactamases. Based on the results, we assume that the novel transglutaminase substrate ensures undisturbed growth of aerial hyphae in Streptomyces mobaraensis by trapping and inactivating hostile beta-lactam antibiotics.

    It was previously shown that enhanced nisin resistance in some mutants was associated with increased expression of three genes, pbp2229, hpk1021, and lmo2487, encoding a penicillin-binding protein, a histidine kinase, and a protein of unknown function, respectively. In the present work, we determined the direct role of the three genes in nisin resistance. Interruption of pbp2229 and hpk1021 eliminated the nisin resistance phenotype. Interruption of hpk1021 additionally abolished the increase in pbp2229 expression. The results indicate that this nisin resistance mechanism is caused directly by the increase in pbp2229 expression, which in turn is brought about by the increase in hpk1021 expression. We also found a degree of cross-protection between nisin and class IIa bacteriocins and investigated possible mechanisms. The expression of virulence genes in one nisin-resistant mutant and two class IIa bacteriocin-resistant mutants of the same wild-type strain was analyzed, and each mutant consistently showed either an increase or a decrease in the expression of virulence genes (prfA-regulated as well as prfA-independent genes). Although the changes mostly were moderate, the consistency indicates that a mutant-specific change in virulence may occur concomitantly with bacteriocin resistance development.

    Background: Given the early age of onset (AOO) of psychotic disorders, it has been assumed that psychotic experiences (PEs) would have a similar early AOO. The aims of this study were to describe (a) the AOO distribution of PEs, (b) the projected lifetime risk of PEs, and (c) the associations of PE AOO with selected PE features. Methods: Data came from the WHO World Mental Health (WMH) surveys. A total of 31 261 adult respondents across 18 countries were assessed for lifetime prevalence of PE. Projected lifetime risk (at age 75 years) was estimated using a 2-part actuarial method. AOO distributions were described for the observed and projected estimates. We examined associations of AOO with PE type metric and annualized PE frequency. Results: Projected lifetime risk for PEs was 7.8% (SE = 0.3), slightly higher than lifetime prevalence (5.8%, SE = 0.2). The median (interquartile range; IQR) AOO based on projected lifetime estimates was 26 (17–41) years, indicating that PEs commence across a wide age range. The AOO distributions for PEs did not differ by sex. Early AOO was positively associated with number of PE types (F = 14.1, P < .001) but negatively associated with annualized PE frequency rates (F = 8.0, P < .001). Discussion: While most people with lifetime PEs have first onsets in adolescence or young adulthood, projected estimates indicate that nearly a quarter of first onsets occur after age 40 years. The extent to which late onset PEs are associated with (a) late onset mental disorders or (b) declining cognitive and/or sensory function need further research. PMID:27038468

    The current study sought to examine the diagnostic overlap in DSM-IV and DSM-5 alcohol use disorder (AUD) and determine the clinical correlates of changing diagnostic status across the 2 classification systems. DSM-IV and DSM-5 definitions of AUD were compared using cross-national community survey data in 9 low-, middle-, and high-income countries. Participants were 31,367 respondents to surveys in the World Health Organization's World Mental Health Survey Initiative. The Composite International Diagnostic Interview, version 3.0, was used to derive DSM-IV and DSM-5 lifetime diagnoses of AUD. Clinical characteristics, also assessed in the surveys, included lifetime DSM-IV anxiety; mood and drug use disorders; lifetime suicidal ideation, plan, and attempt; general functional impairment; and psychological distress. Compared with DSM-IV AUD (12.3%, SE = 0.3%), the DSM-5 definition yielded slightly lower prevalence estimates (10.8%, SE = 0.2%). Almost one-third (n = 802) of all DSM-IV abuse cases switched to subthreshold according to DSM-5 and one-quarter (n = 467) of all DSM-IV diagnostic orphans switched to mild AUD according to DSM-5. New cases of DSM-5 AUD were largely similar to those who maintained their AUD across both classifications. Similarly, new DSM-5 noncases were similar to those who were subthreshold across both classifications. The exception to this was with regard to the prevalence of any lifetime drug use disorder. In this large cross-national community sample, the prevalence of DSM-5 lifetime AUD was only slightly lower than the prevalence of DSM-IV lifetime AUD. Nonetheless, there was considerable diagnostic switching, with a large number of people inconsistently identified across the 2 DSM classifications.

    2016-02-01

    Full Text Available Cationic polyimines polymerized through aromatically conjugated bis-imine linkages and intra-molecular cross-linking were found to be a new class of effective transfection materials for their flexibility in structural optimization, responsiveness to intracellular environment, the ability to facilitate endosome escape and cytosol release of the nucleic acids, as well as self-metabolism. When three phthalaldehydes of different substitution positions were used to polymerize highly branched low molecular weight polyethylenimine (PEI-1.8K, the product through ortho-phthalimines (named PPOP showed significantly higher transfection activity than its two tere- and iso-analogues (named PPTP and PPIP. Physicochemical characterization confirmed the similarity of three polyimines in pH-responded degradability, buffer capacity, as well as the size and Zeta potential of the polyplexes formed from the polymers. A mechanistic speculation may be that the ortho-positioned bis-imine linkage of PPOP may only lead to the straight trans-configuration due to steric hindrance, resulting in larger loops of intra-polymer cross-linking and more flexible backbone.

    commissioned a comprehensive survey to determine user satisfaction using the American Customer Satisfaction Index (ACSI) approach. The results show that, overall, the users are highly satisfied with the EOSDIS systems and services as the EOSDIS ACSI score outperformed both the averages for U.S. companies and for Federal Agencies. Noteworthy was the fact that there was no statistical difference in the quality scores received by the various EOSDIS data centers. The response indicated that customer support provided by the EOSDIS Distributed Active Archive Centers (DAACs) is "world class" and that a very high number of users intend to use EOSDIS in the future (90%) and to recommend it to their colleagues (86%). The survey highlighted areas that, if improved, could lead to increased user satisfaction, including overall product quality, product documentation, and product selection and ordering processes. These results will be factored into NASA's evolution planning.

Persistence was not significantly different between irbesartan and losartan monotherapy (76% for both; P > 0.05), but was significantly higher with irbesartan + HCTZ versus losartan + HCTZ (96% vs 73%, respectively; P = 0.001). Patients treated with ARBs reported fewer CV events than those receiving ACEIs or CCBs (4.3% vs 7.0% and 11.0%, respectively; P < 0.001). Within the ARB class, the lowest rate was with irbesartan (3.0% vs 4.6%-5.0% for other ARBs; P < 0.02). In this real-world setting, hypertensive adults treated with ARBs versus β-blockers or diuretics were more likely to have evidence-based target BP recorded. In addition, patients using ARBs versus ACEIs or CCBs had fewer reports of CV events. Copyright © 2011 Elsevier HS Journals, Inc. All rights reserved.

    Modifiable health-related behaviours tend to cluster among most vulnerable sectors of the population, particularly those at the bottom of the social hierarchy. This study aimed to identify the clusters of health-related behaviours in 27 European countries and to examine the socioeconomic inequalities in these clusters. Data were from Eurobarometer 72.3-2009, a cross-sectional survey of 27 European countries. The analyses were conducted in 2016. The main sections of the survey included questions pertaining to sociodemographic factors, health-related behaviours, and use of services. In this study, those aged 18 years and older were included. We selected five health-related behaviours, namely smoking, excessive alcohol consumption, frequent fresh fruit consumption, physical activity and dental check-ups. Socioeconomic position was indicated by education, subjective social status and difficulty in paying bills. Latent class analysis was conducted to explore the clusters of these five behaviours. Multinomial logistic regression model was used to examine the relationships between the clusters and socioeconomic positions adjusting for age, gender, marital status and urbanisation. The eligible total population was 23,842. Latent class analysis identified three clusters; healthy, moderate and risky clusters in this European population. Individuals with the lowest socioeconomic position were more likely to have risky and moderate clusters than healthy cluster compared to those with the highest socioeconomic position. There were clear socioeconomic gradients in clusters of health-related behaviours. The findings highlight the importance of adopting interventions that address multiple health risk behaviours and policies that tackle the social determinants of health-related behaviours.

    We have previously demonstrated lactational transfer of T cell-based immunity from dam to foster pup. In the short term, a significant part of transferred immunity is passive cellular immunity. However, as time progresses, this is replaced by what we have described as maternal educational immunity such that by young adulthood, all immune cells responding to a foster dam immunogen are the product of the foster pup's thymus. To reduce confounding factors, this original demonstration used congenic/syngeneic dam and foster pup pairs. In this study, we investigated lactational transfer of immunity to Mycobacterium tuberculosis in MHC class I-mismatched animals, as well as from Th1-biased dams to Th2-biased foster pups. Using immunized C57BL/6J dams, lactational transfer to nonimmunized BALB/cJ foster pups resulted in much greater immunity than direct immunization in 5-wk-old pups (ex vivo assay of pup splenocytes). At this age, 82% of immunogen-responding cells in the pup spleen were produced through maternal educational immunity. FVB/NJ nonimmunized foster recipients had a greater number of maternal cells in the spleen and thymus but a much larger percentage was Foxp3(+), resulting in equivalent immunity to direct immunization. Depletion of maternal Foxp3(+) cells from pup splenocytes illustrated a substantial role for lactationally transferred dam regulatory T cells in suppression of the ex vivo response in FVB/NJ, but not BALB/cJ, recipients. We conclude that lactational transfer of immunity can cross MHC class I barriers and that Th1 immunity can be imparted to Th2-biased offspring; in some instances, it can be greater than that achieved by direct immunization.

    Full Text Available Children begin to observe curiously the living and non-living nature they live in. They try to know and define the objects with their various characteristics. In time, they perceive the world and environment regularly and systematically. Some wrong information developed uniquely by the students in such a manner that out of scientific facts in time causes significant obstacles within the learning process. As the children develop, learn and their interaction with the environment increases, the living and non-living concepts take form and have new meanings. In our study, it has been tried to be revealed by means of quantitative data that whether the characteristics of living and non-living things differentiate from each other by gender according to them. Totally 1066 students participated in our study, of which 531 are females and 535 are males, in 12 primary schools determined at random in 7 provinces of Turkey, being one province from each region. In this study descriptive survey model is used. The data was obtained from a questionnaire which is consisting of 14 questions. The quantitative data obtained was analyzed by using SPSS 14 package programme. In this research chi-square test was used for analyzing data. 49.5 % of the female students and 50.5 % of the male students have emphasized that they learned the existence of living and non-living things around them in their families for the first time. 51.4 % of the female students and 48.6 % of the male students have stated that human comes to their minds when living thing is said. 57.9 % of the female students and 42.1 % of the male students participated in the survey have stated that moving is the first thing coming to their mind when the characteristics of living things is said. Whereas 520 students identified that not-moving is the first thing coming to their mind when the characteristics of non-living things is said, this rate is 49% for female students and 51% for male students.

    2012-03-01

    We introduce a valid parametric family of cross-covariance functions for multivariate spatial random fields where each component has a covariance function from a well-celebrated Matérn class. Unlike previous attempts, our model indeed allows for various smoothnesses and rates of correlation decay for any number of vector components.We present the conditions on the parameter space that result in valid models with varying degrees of complexity. We discuss practical implementations, including reparameterizations to reflect the conditions on the parameter space and an iterative algorithm to increase the computational efficiency. We perform various Monte Carlo simulation experiments to explore the performances of our approach in terms of estimation and cokriging. The application of the proposed multivariate Matérnmodel is illustrated on two meteorological datasets: temperature/pressure over the Pacific Northwest (bivariate) and wind/temperature/pressure in Oklahoma (trivariate). In the latter case, our flexible trivariate Matérn model is valid and yields better predictive scores compared with a parsimonious model with common scale parameters. © 2012 American Statistical Association.

    Executive dysfunction is a common feature of schizophrenia and bipolar disorder (BP). While deficits in social cognitive abilities, including theory of mind (ToM), have been suggested to be specific to schizophrenia, available evidence suggests that there is also a significant overlap in social cognitive performances of both disorders. However, there is significant heterogeneity of executive dysfunction and ToM deficits in BP and schizophrenia. Cross-diagnostic data-driven methods can reveal potential neurocognitive subtypes characterized by relatively selective deficits in social cognition. Neurocognitive subgroups were investigated using latent class analysis, based on executive functions and ToM, in a mixed sample of 97 clinically stable patients with schizophrenia or BP and 27 healthy controls. Four neurocognitive subgroups, including a "neuropsychologically normal" cluster, a severe global impairment cluster and two clusters of mixed cognitive profiles were found. Severe impairment cluster was characterized by particularly severe ToM deficits and predominantly included patients with schizophrenia. Schizophrenia patients in this cluster had severe negative symptoms. In contrast, individuals with BP compared to schizophrenia patients were more likely to be included in the "neuropsychologically normal" cluster. Identification of distinctive neurobiological subtypes of patients based on social and non-social cognitive profiles can improve classification of major psychoses. Neurocognitive subgroupings of patients might be also beneficial for intervention strategies including cognitive rehabilitation. Copyright © 2016 Elsevier B.V. All rights reserved.

    Elderly suicides rates are associated with socio-economic status and life expectancy. Although suicide rates in younger people are associated with both higher and lower levels of educational attainment, little is known about this association in the elderly. The relationship between Human Development Index (HDI)--a composite index measuring average achievements on three basic dimensions of human development (life expectancy, educational attainment and socio-economic status)--and elderly suicide rates was examined in a cross-national study utilizing secondary data from the World Health Organization and the United Nations. There was a significant curvilinear (inverted U-shaped curve) relationship between elderly suicide rates in males and the HDI, fitting the quadratic equation y = a + bx - cx2. A similar curvilinear relationship was observed in females, but the significance level only approached 0.05. A model with four sequential stages was proposed to explain the findings: (i) low elderly suicide rate--low human development society; (ii) high elderly suicide rate--low human development society; (iii) high elderly suicide rate--high human development society; and (iv) low elderly suicide rate--high human development society.

    Objective To assess and compare health system performance across six middle-income countries that are strengthening their health systems in pursuit of universal health coverage. Design Cross-sectional analysis from the World Health Organization Study on global AGEing and adult health, collected between 2007 and 2010. Setting Six middle-income countries: China, Ghana, India, Mexico, Russia and South Africa. Participants Nationally representative sample of adults aged 50 years and older. Main outcome measures We present achievement against key indicators of health system performance across effectiveness, cost, access, patient-centredness and equity domains. Results We found areas of poor performance in prevention and management of chronic conditions, such as hypertension control and cancer screening coverage. We also found that cost remains a barrier to healthcare access in spite of insurance schemes. Finally, we found evidence of disparities across many indicators, particularly in the effectiveness and patient centredness domains. Conclusions These findings identify important focus areas for action and shared learning as these countries move towards achieving universal health coverage.

    Full Text Available Background: Disability is important public health problem especially among elderly. Gender difference between disability statuses of elderly is quite obvious. Very little information about disability in a rural area hinders the proper formulation of policies. Objectives: This study determines role of selected socio-demographic factors in explaining gender differences in disability among rural elderly. Materials and Methods: A community-based cross-sectional study was carried out from January 12 to December 12. 227 (Two hundred and twenty seven(aged 60 years and above were selected from a rural village of Pune, Maharashtra. Data collected using newly published World Health Organization Disability Assessment Schedule 2.0. Chi-square test and odds ratio used for determining the association. Results: The result confirms higher prevalence of disability among females than that of males. Disability was found to be statistically significant with gender. Marital status and education were effect modifier of disability. Disability in mobility was most common. In almost all domain disability was more common among elderly women. Conclusion: Greater prevalence of disability among aging women compared with men requires more attention to be given toward them for proper planning of scarce health services.

    What do searchers find when they look for literature on homosexuality? This question has profound implications for older as well as younger gays in their coming out, as well as in their subsequent identity development. Library records provide credible data to answer the question, since they represent relatively free sources of information, unlike data from bookstores, publishers, and some World Wide Web sites. The records of WorldCat, the world's largest union database of library records, comprise over 30 million records listed in the Online Computer Library Center. For the purposes of the study, 18,757 records listed under "Homosexuality," "Gay Men," and "Gays" were downloaded; records for "Lesbian" and "Lesbians" were not examined. Findings of the study suggest that while there has indeed been considerable growth in terms of the quantity of gay literature produced since 1969, such gains may be offset by the deteriorating quality of cataloging copy, which makes the experience of browsing records a discouraging and confusing one.

    So far, many studies on educational games have been carried out in America and Europe. Very few related empirical studies, however, have been conducted in China. This study, combining both quantitative with qualitative research methods, possibly compensated for this regret. The study compared data collected from two randomly selected classes (out of 13 classes) under computer game-based instruction (CGBI) and non-computer game-based instruction (NCGBI), respectively, in a senior high school located in Nanjing, Capital of Jiangsu Province, in China. The participants were 103 students, composed of 52 boys and 51 girls (aged 17-18 years old). The following conclusion was reached: (1) participants under CGBI obtained significantly greater learning achievement than those under NCGBI; (2) participants were significantly more motivated by CGBI compared with NCGBI; (3) there were no significant differences in learning achievement between boys and girls; although (4) boys were significantly more motivated by CGBI than girls. Both disadvantages and advantages were discussed, together with directions for future research.

    Previous studies on cardiovascular risk profile in different socioeconomic status were focused on younger populations and many of them have not been able to take into account age and sex differences. To investigate the relationship of occupational social class with the prevalence of cardiovascular disease risk factors and cardiovascular diseases in younger (or=65 years) men and women. A population-based-cross sectional study was conducted in a general community in Norfolk, United Kingdom. Participants were 23,085 men and women aged 40-79 years, recruited from general practice age-sex registers as part of European Prospective Investigation into Cancer-Norfolk (EPIC-Norfolk). The prevalence of cardiovascular risk factors and cardiovascular diseases were examined. The prevalence of smoking was significantly higher in those in manual social classes particularly in the younger (social classes were more likely to be smokers compared to older women in the same social class. Being in manual social classes was associated with higher cholesterol levels in women but lower cholesterol levels in men. Manual social class was associated with higher physical activity in those younger than 65 years but this association was reversed in those 65 years or older. Occupational social class is differently related to cardiovascular risk factors in individuals depending on their age and sex. This may reflect differences in behavior at work and leisure, which vary by sex and pre- and postretirement. Interventions to promote health and reduce social inequalities need to take age and gender into account. Copyright 2006 S. Karger AG, Basel.

    There are cross term interference problems in multi-component signal analysis on Wigner-Ville distribution, which is a kind of bilinear time-frequency distribution. A time-frequency joint algorithm based on Ensemble Empirical Mode Decomposition ( EEMD) and Cohen class was proposed. EEMD algorithm was adopted to decompose the signal into a collection of Intrinsic Mode Functions ( IMF). Cohen class time-frequency transform and superposition on each component except the pseudo one were carried out. The signal time-frequency distribution was obtained and the cross terms among IMF in internal signals were eliminated. The simulation study of time-frequency on EEMD and Cohen class was conducted. Simulation results of wavelet decomposition, Cohen class joint time-frequency algorithm and Empirical Mode Decomposition (EMD)and Cohen class joint algorithm were compared. It turned out that the EEMD and Cohen class joint algorithm has the best effect on suppressing the cross term form, diminishing the reconstruction error and restraining interference of time-frequency characteristics caused by noise.%Wigner-Ville分布是一种双线性时频分布,对多分量信号分析存在交叉项干扰.本文提出了一种基于EEMD和Cohen类时频融合算法,该算法采用EEMD算法将信号从频域上分离为若干个固有模态函数之和,再对伪分量之外的各分量进行Cohen类时频变换并叠加,得到信号的时频分布,消除了信号内部各模态函数之间时频分布的交叉项.通过对EEMD和Cohen类时频融合算法进行仿真,与小波分解和Cohen类联合时频算法、EMD和Cohen类联合时频算法的仿真进行比较,结果表明,该算法抑制交叉项效果最好,重构误差最小,同时抑制了噪声对时频特征的干扰.

    This study aims to analyze culture-specific development of maternal interactional behavior longitudinally. Rural Cameroonian Nso mothers (n = 72) and German middle-class mothers (n = 106) were observed in free-play interactions with their 3- and 6-month-old infants. Results reveal the expected shift from a social to a nonsocial focus only in the German middle-class mothers' play interactions but not the rural Nso mothers' play. Nso mothers continue their proximal interactional style with a focus on body contact and body stimulation, whereas German middle-class mothers prefer a distal style of interaction with increasing object-centeredness. These cultural differences are in line with broader cultural models and become more accentuated as the infants grow older. (c) 2015 APA, all rights reserved).

    Full Text Available In the third millennium of the Christian era, which is characterised by the emergence of a world economy and eventually a world society, the concept of world law is needed to embrace not only the traditional disciplines of public international law, and comparative law, but also the common underlying legal principles applicable in world trade, world finance, transnational transfer of technology and other fields of world economic law, as well as in such emerging fields as the protection of the world's environment and the protection of universal human rights. World law combines inter-state law with the common law of humanity and the customary law of various world communities.

    To analyse gender differences in the relationship of individual social class, employment status and neighbourhood unemployment rate with present type 2 diabetes mellitus (T2DM). Five cross-sectional studies. Studies were conducted in five regions of Germany from 1997 to 2006. The sample consisted of 8871 individuals residing in 226 neighbourhoods from five urban regions. Prevalent T2DM. We found significant multiplicative interactions between gender and the individual variables--social class and employment status. Social class was statistically significantly associated with T2DM in men and women, whereby this association was stronger in women (lower vs higher social class: OR 2.68 (95% CIs 1.66 to 4.34)) than men (lower vs higher social class: OR 1.78 (95% CI 1.22 to 2.58)). Significant associations of employment status and T2DM were only found in women (unemployed vs employed: OR 1.73 (95% CI 1.02 to 2.92); retired vs employed: OR 1.77 (95% CI 1.10 to 2.84); others vs employed: OR 1.64 (95% CI 1.01 to 2.67)). Neighbourhood unemployment rate was associated with T2DM in men (high vs low tertile: OR 1.52 (95% CI 1.18 to 1.96)). Between-study and between-neighbourhood variations in T2DM prevalence were more pronounced in women. The considered covariates helped to explain statistically the variation in T2DM prevalence among men, but not among women. Social class was inversely associated with T2DM in both men and women, whereby the association was more pronounced in women. Employment status only affected T2DM in women. Neighbourhood unemployment rate is an important predictor of T2DM in men, but not in women.

    India has had two stages of growth, both related to consumption since 1947. The first was based on developing economic self sufficiency; the second on rising disposable income. It is now entering its third period of consumption growth which sees it entering the world stage as one of the largest consumers in the world. This paper explains the factors that are driving this dramatic shift from the emerging middle classes to the patterns of consumption and investment in India today.

    Chicago, the host city for the annual meeting of the RSNA (Radiological Society of North America), is the quintessential place to obtain certain foods, among them deep dish pizza, the Italian beef sandwich, and the Chicago-style hot dog. Given some appropriate nutritional concerns about these items, it is important to realize that healthier alternatives are grown, produced, and sold regionally. Chicago has also for years been known as one of America's great restaurant towns. However, the French delicacy foie gras cannot be found on the menu of any of its five-star establishments, as the sale of this dish became illegal in 2006.

    2011-08-01

    Full Text Available Supply Chain Management is the optimized operation of the supply chain. It requires someone who can optimize the resources while at the same time interacting with the forces that cause pressures against the supply chain. Itrequires someone who can develop a strategic plan for continuous optimization and improvement. It requires a supply chain manager. So what is a supply chain manager? This individual is someone who can identify the critical resources that move through the supply chain; someone who can identify the forces that come into play and that affect the performance of these resources; and someone who can use this information to develop goals,objectives, and a strategy around which to optimize the flow of the supply chain. This sounds like a big task, and it is. But numerous tools are available to help you with this task, and as we move forward we will learn more about these tools. There are several types of managers, and they can be categorized in numerous ways. One type is the sunrise manager who has a view toward the future, as opposed to the sunset manager who fights fires in the here and now. Another way to classify managers is to consider their attitudes toward their subordinates. The two extremes are the authoritarian manager and the participative manager.

    Full Text Available Abstract Background Important unanswered questions remain on the impact of international sporting events on the sex industry. Speculation about increased demand and supply of sex work often generates significant attention, but also additional funding for HIV programmes. This study assessed whether changes occurred in the demand and supply of paid sex during the 2010 Soccer World Cup in South Africa. Methods Trained sex worker interviewers conducted face-to-face semi-structured interviews among consenting female sex workers during May-September 2010. Using bivariate analyses we compared supply, demand, sexual risk-taking, and police and health services contact pre-World Cup, to levels during the World Cup and after the event. Results No increases were detected in indicators of sex work supply, including the proportion of sex workers newly arrived in the city ( 92.4% in all phases. Health-care utilisation decreased non-significantly from the pre- to during World Cup period (62.4% to 57.0%; P = 0.075. Across all periods, about thirty percent of participants had interacted with police in the preceding month, two thirds of whom had negative interactions. Conclusions Contrary to public opinion, no major increases were detected in the demand or supply of paid sex during the World Cup. Although the study design employed was unable to select population-based samples, these findings do not support the public concern and media speculation prior to the event, but rather signal a missed opportunity for public health action. Given the media attention on sex work, future sporting events offer strategic opportunities to implement services for sex workers and their clients, especially as health service utilisation might decrease in this period.

  19. Dependent Classes

    DEFF Research Database (Denmark)

    Gasiunas, Vaidas; Mezini, Mira; Ostermann, Klaus

    2007-01-01

    Virtual classes allow nested classes to be refined in subclasses. In this way nested classes can be seen as dependent abstractions of the objects of the enclosing classes. Expressing dependency via nesting, however, has two limitations: Abstractions that depend on more than one object cannot...... be modeled and a class must know all classes that depend on its objects. This paper presents dependent classes, a generalization of virtual classes that expresses similar semantics by parameterization rather than by nesting. This increases expressivity of class variations as well as the flexibility...... of their modularization. Besides, dependent classes complement multi-methods in scenarios where multi-dispatched abstractions rather than multi-dispatched method are needed. They can also be used to express more precise signatures of multi-methods and even extend their dispatch semantics. We present a formal semantics...

  5. Finding meaning in a noisy world: exploring the effects of referential ambiguity and competition on 2·5-year-olds' cross-situational word learning.

    Science.gov (United States)

    Bunce, John P; Scott, Rose M

    2016-04-07

    While recent studies suggest children can use cross-situational information to learn words, these studies involved minimal referential ambiguity, and the cross-situational evidence overwhelmingly favored a single referent for each word. Here we asked whether 2·5-year-olds could identify a noun's referent when the scene and cross-situational evidence were more ambiguous. Children saw four trials in which a novel word occurred with four novel objects; only one object consistently co-occurred with the word across trials. The frequency of distracter objects varied across conditions. When all distracter referents occurred only once (no-competition), children successfully identified the noun's referent. When a high-probability competitor referent occurred on three trials, children identified the target referent if the competitor was absent on the third trial (short-competition) but not if it was present until the fourth trial (long-competition). This suggests that although 2·5-year-olds' cross-situational learning scales up to more ambiguous scenes, it is disrupted by high-probability competitor referents.

    Full Text Available Manufacturing is playing a significant role in its re-shoring into America. Companies are grappling with ways to obtain that competitive advantage by distinguishing themselves through their intellectual capabilities, process improvements, technology, people, shop floor management and information flows. The purpose of this paper is to describe the effort at Farmingdale State College to educate our students in understanding Production Management and Master Production Schedule (MPS. We are trying to prepare students for entry into the workforce. By using a Real world ERP tool in the classroom while complimenting this learning with touring local manufacturers who use this tool and having production control experts in our classrooms. [1] The opportunity presents itself for these students to visit real world manufacturers using the same tool these students use in the classroom, the Infor Visual ERP. Each semester students go to a local manufacturer to see how the product is made and the ERP system is used to make it. Each semester a subject matter expert, SME, in manufacturing comes into the class and talks about how they use their ERP to perform their functional responsibilities. Students go into these companies and sit down with these Production Manufacturing and IT SME's to see how they use the modules in their ERP system from estimating, Production Management, MPS to delivery and payment. From the manufacturing window to the Master Schedule Window students learn from these companies SME's just how they perform their functions, how they use this tool. Then that is replicated this in the classroom lab assignments for students to better understand Production Management, scheduling and work order integrity. They identify the desired schedule (forecast and populate a Master Production Schedule. They create a BOM with work orders adding operations and material. The Production Management/Control is the function of directing or regulating the movement of

    2010-02-28

    The use of positional scanning peptide libraries in combination with biometrical analysis is one of the few approaches, which allows the identification of stimulatory peptides for T cells of unknown specificity. Despite the successful application of this strategy in different studies, not every T cell is suited for analysis. For as yet unknown reasons some T cells do not recognize these highly complex libraries, and even more importantly the predictive capacity of the current approach shows high variability among individual T cell clones and their TCRs. A number of factors probably contribute to differences in T cell recognition and have to be taken into account in order to overcome these difficulties. Our results suggest that the ability of some T cells to recognize peptides in the context of more than one HLA class II molecule expressed by autologous APCs could diminish the predictive capacity of the approach. In contrast, the use of B cell lines expressing single HLA class II molecules as APCs instead of autologous peripheral blood mononuclear cells markedly improves the capacity to identify target peptides for this type of T cells.

  16. Quantifying the impoverishing effects of purchasing medicines: a cross-country comparison of the affordability of medicines in the developing world.

    Directory of Open Access Journals (Sweden)

    Laurens M Niëns

    Full Text Available BACKGROUND: Increasing attention is being paid to the affordability of medicines in low- and middle-income countries (LICs and MICs where medicines are often highly priced in relation to income levels. The impoverishing effect of medicine purchases can be estimated by determining pre- and postpayment incomes, which are then compared to a poverty line. Here we estimate the impoverishing effects of four medicines in 16 LICs and MICs using the impoverishment method as a metric of affordability. METHODS AND FINDINGS: Affordability was assessed in terms of the proportion of the population being pushed below US$1.25 or US$2 per day poverty levels because of the purchase of medicines. The prices of salbutamol 100 mcg/dose inhaler, glibenclamide 5 mg cap/tab, atenolol 50 mg cap/tab, and amoxicillin 250 mg cap/tab were obtained from facility-based surveys undertaken using a standard measurement methodology. The World Bank's World Development Indicators provided household expenditure data and information on income distributions. In the countries studied, purchasing these medicines would impoverish large portions of the population (up to 86%. Originator brand products were less affordable than the lowest-priced generic equivalents. In the Philippines, for example, originator brand atenolol would push an additional 22% of the population below US$1.25 per day, whereas for the lowest priced generic equivalent this demographic shift is 7%. Given related prevalence figures, substantial numbers of people are affected by the unaffordability of medicines. CONCLUSIONS: Comparing medicine prices to available income in LICs and MICs shows that medicine purchases by individuals in those countries could lead to the impoverishment of large numbers of people.

    Full Text Available After the wars against Atjeh (1873-1907 finished, Dutch rule over the Dutch East India was total. The Dutch East Indies Red Cross (DEIRC awaited a new task, preparing to give aid in the case of a foreign invasion. The problem was that the end of the wars against the autochthonous “rebellions” also meant the end of Red Cross visibility and in the minds of many, the end to Red Cross urgency. Aid in wars against a real opponent is from a point of public relations much more important than the preparation of aid against an unknown opponent. “Work in times of peace” had to be the answer to this problem, but this work was only in name, and not de facto different from preparation of aid in times of war. Through “peace work” the DEIRC prepared itself for the war-task. To be able to fulfil the war-task the Red Cross had to have enough doctors, nurses, and stretcher-bearers. Visible peace-work had to provide for that. It enlarged the Red Cross’ popularity and trained its volunteers. However, at the beginning of 1942, when the Japanese invaded the Dutch East Indies, it turned out to be too little, too late.Tras el fin de las guerras contra Aceh (1873-1907, el dominio holandés sobre la India Oriental Holandesa fue total. La Cruz Roja de las Indias Orientales Holandesas (DEIRC quedaba a la espera de una nueva tarea: prepararse para proporcionar ayuda en caso de una invasión extranjera. El problema era que el final de las guerras contra las “rebeliones” autóctonas también significaba el fin de la visibilidad de la Cruz Roja y, a juicio de muchos, el final de la perentoriedad de la Cruz Roja. El socorro en guerras contra un adversario real era desde el punto de vista de las relaciones públicas mucho más importante que los preparativos de socorro contra un enemigo desconocido. El “trabajo en tiempo de paz” debía ser la respuesta a este problema, si bien resultó diferente solo de palabra, no de hecho, en relación a los preparativos

    Full Text Available From the end of the 19th to the beginning of the 20th century, Morocco’s modernizing projects included plans for signing up to the Geneva Convention and creating a local Red Cross/Crescent society. These plans initially stemmed from the convergence of Moroccan administrative/military reforms and Spanish “regenerationist” interventions. They ran parallel to developments in leading Islamic countries such as Egypt, Persia and the Ottoman Empire though they would have to wait till the country’s independence from Franco-Spanish domination in 1956 to become a reality. Beyond their lack of actual results, those early initiatives would serve as legal ground for Morocco’s “humanitarian sovereignty”, tacitly confirmed by the provisions of the Algeciras Act of 1906. In the following two decades, the resilience of this sovereignty would reveal itself in the sustained competition between the Spanish and the French Red Cross for “humanitarian hegemony” in the country, and also in the repeated and nearly successful demands to establish a local Red Cross/Crescent that were made to the International Committee of the Red Cross by the insurgent leader Abdelkrim during the so-called Rif War.Hacia finales del siglo XIX y comienzos del XX, los proyectos de modernización de Marruecos incluyeron planes de adhesión a la Convención de Ginebra y de creación de una sociedad local de la Cruz/Media Luna Roja. Estos planes surgieron de la convergencia entre las reformas administrativas/militares marroquíes y las intervenciones “regeneracionistas” españolas. Transcurrieron en paralelo con los desarrollos en países islámicos líderes como Egipto, Persia y el Imperio Otomano, aunque habrían de esperar para hacerse realidad hasta la independencia del país de la dominación franco-española en 1956. Más allá de la falta de resultados concretos, estas tempranas iniciativas servirían como marco legal a la “soberanía humanitaria” de Marruecos

    The objective of this study was to empirically demonstrate the use of a new framework for describing the strategies used to implement quality improvement interventions and provide an example that others may follow. Implementation strategies are the specific approaches, methods, structures, and resources used to introduce and encourage uptake of a given intervention's components. Such strategies have not been regularly reported in descriptions of interventions' effectiveness, or in assessments of how proven interventions are implemented in new settings. This lack of reporting may hinder efforts to successfully translate effective interventions into "real-world" practice. A recently published framework was designed to standardize reporting on implementation strategies in the implementation science literature. We applied this framework to describe the strategies used to implement a single intervention in its original commercial care setting, and when implemented in community health centers from September 2010 through May 2015. Per this framework, the target (clinic staff) and outcome (prescribing rates) remained the same across settings; the actor, action, temporality, and dose were adapted to fit local context. The framework proved helpful in articulating which of the implementation strategies were kept constant and which were tailored to fit diverse settings, and simplified our reporting of their effects. Researchers should consider consistently reporting this information, which could be crucial to the success or failure of implementing proven interventions effectively across diverse care settings. clinicaltrials.gov Identifier: NCT02299791.

    Full Text Available In school settings, self-control is central to the ability of learners to complete their academic work successfully. Learners’ self-control is directly influenced by the ways in which educators execute their work, including their instructional explanations, their classroom management, and the expectations that they express to their learners. Our research on this phenomenon investigated Finnish and Swedish learners in upper secondary schools. Not only is the use of digital technology very different in these two countries; the autonomy and status of educators are as well. This article compares the empirical significance of antecedents of learners’ academic self-control in the two national settings by surveying 2191 learners in Swedish and Finnish schools. Our analysis applies structural equation modeling to two cross-sectional datasets, and the results reveal that the associations between educators’ instructional explanations, classroom management, and their high expectations on the one hand and learners’ academic self-control on the other are stronger overall among Finnish students than among Swedish students. Furthermore, the association between digital technology use and learners’ perceptions of conflict between school norms and Internet opportunities are much stronger in the Swedish sample than the Finnish sample. Lastly, we discuss the meaning of these results and their possible implications for research and practice.

    ABSTRACT Given recent updates to the postpartum contraception recommendations in the fifth edition of the Medical Eligibility Criteria for Contraceptive Use (MEC), published by the World Health Organization (WHO), the purpose of this qualitative study was to assess the extent to which national family planning policies in sub-Saharan African countries are in agreement with the WHO MEC, particularly with regard to postpartum contraceptive use. WHO headquarters sent questionnaires to country-level focal points to complete with their Ministry of Health counterparts. Between February and May 2016, 23 of 32 (72%) surveys were completed. All respondents reported that their countries had used the MEC document in the past, with most reporting that they had used the guidance as a reference (n = 20, 87%), for training purposes (n = 19, 83%), to change clinical practices (n = 17, 74%), and to develop national policies (n = 16, 70%). While many respondents (16, 70%) indicated their countries already include immediate postpartum intrauterine device insertion among breastfeeding women in their family planning policies, few reported currently allowing use of progestogen-only pills (n = 8, 35%) or implants (n = 8, 35%) during the immediate postpartum period (i.e., less than 48 hours after delivery) for breastfeeding women. A higher percentage of respondents indicated their countries allowed breastfeeding women the option of progestogen-only pills (n = 16, 70%) and implants (n = 13, 57%) between 48 hours and 6 weeks postpartum. Findings from this baseline assessment suggest that many countries may benefit from training and policy formulation support to adapt both new WHO MEC updates as well as existing recommendations from previous MEC revisions into national family planning guidelines.

  6. Cross-national analysis of the associations between traumatic events and suicidal behavior: findings from the WHO World Mental Health Surveys.

    Dan J Stein

    Full Text Available BACKGROUND: Community and clinical data have suggested there is an association between trauma exposure and suicidal behavior (i.e., suicide ideation, plans and attempts. However, few studies have assessed which traumas are uniquely predictive of: the first onset of suicidal behavior, the progression from suicide ideation to plans and attempts, or the persistence of each form of suicidal behavior over time. Moreover, few data are available on such associations in developing countries. The current study addresses each of these issues. METHODOLOGY/PRINCIPAL FINDINGS: Data on trauma exposure and subsequent first onset of suicidal behavior were collected via structured interviews conducted in the households of 102,245 (age 18+ respondents from 21 countries participating in the WHO World Mental Health Surveys. Bivariate and multivariate survival models tested the relationship between the type and number of traumatic events and subsequent suicidal behavior. A range of traumatic events are associated with suicidal behavior, with sexual and interpersonal violence consistently showing the strongest effects. There is a dose-response relationship between the number of traumatic events and suicide ideation/attempt; however, there is decay in the strength of the association with more events. Although a range of traumatic events are associated with the onset of suicide ideation, fewer events predict which people with suicide ideation progress to suicide plan and attempt, or the persistence of suicidal behavior over time. Associations generally are consistent across high-, middle-, and low-income countries. CONCLUSIONS/SIGNIFICANCE: This study provides more detailed information than previously available on the relationship between traumatic events and suicidal behavior and indicates that this association is fairly consistent across developed and developing countries. These data reinforce the importance of psychological trauma as a major public health problem

    Background Current trends in population aging affect both recipients and providers of informal family caregiving, as the pool of family caregivers is shrinking while demand is increasing. Epidemiologic research has not yet examined the implications of these trends for burdens experienced by aging family caregivers. Methods Cross-sectional community surveys in 20 countries asked 13,892 respondents ages 50+ about the objective (time, financial) and subjective (distress, embarrassment) burdens they experience in providing care to first-degree relatives with 12 broadly-defined serious physical and mental conditions. Differential burden was examined by country income category, kinship status, and type of condition. Results Among the 26.9-42.5% respondents in high, upper-middle, and low/lower-middle income countries reporting serious relative health conditions, 35.7-42.5% reported burden. Of those, 25.2-29.0% spent time and 13.5-19.4% money, while 24.4-30.6% felt distress and 6.4-21.7% embarrassment. Mean caregiving hours/week given any was 16.6-23.6 (169.9-205.8 hours/week/100 people ages 50+). Burden in low/lower-middle income countries was 2-3-fold higher than in higher income countries, with financial burden given any averaging 14.3% of median family income in high, 17.7% in upper-middle, and 39.8% in low/lower-middle income countries. Higher burden was reported by women than men and for conditions of spouses and children than parents or siblings. Conclusions Uncompensated family caregiving is an important societal asset that offsets rising formal healthcare costs. However, the substantial burdens experienced by aging caregivers across multiple family health conditions and geographic regions threaten the continued integrity of their caregiving capacity. Initiatives supporting older family caregivers are consequently needed, especially in low/lower-middle income countries. PMID:22877824

    Full Text Available Suicide is a leading cause of death worldwide. Mental disorders are among the strongest predictors of suicide; however, little is known about which disorders are uniquely predictive of suicidal behavior, the extent to which disorders predict suicide attempts beyond their association with suicidal thoughts, and whether these associations are similar across developed and developing countries. This study was designed to test each of these questions with a focus on nonfatal suicide attempts.Data on the lifetime presence and age-of-onset of Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV mental disorders and nonfatal suicidal behaviors were collected via structured face-to-face interviews with 108,664 respondents from 21 countries participating in the WHO World Mental Health Surveys. The results show that each lifetime disorder examined significantly predicts the subsequent first onset of suicide attempt (odds ratios [ORs] = 2.9-8.9. After controlling for comorbidity, these associations decreased substantially (ORs = 1.5-5.6 but remained significant in most cases. Overall, mental disorders were equally predictive in developed and developing countries, with a key difference being that the strongest predictors of suicide attempts in developed countries were mood disorders, whereas in developing countries impulse-control, substance use, and post-traumatic stress disorders were most predictive. Disaggregation of the associations between mental disorders and nonfatal suicide attempts showed that these associations are largely due to disorders predicting the onset of suicidal thoughts rather than predicting progression from thoughts to attempts. In the few instances where mental disorders predicted the transition from suicidal thoughts to attempts, the significant disorders are characterized by anxiety and poor impulse-control. The limitations of this study include the use of retrospective self-reports of lifetime occurrence and

    2014-01-01

    To be habitable, a world (planet or moon) does not need to be located in the stellar habitable zone (HZ), and worlds in the HZ are not necessarily habitable. Here, we illustrate how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ. Scientists have developed a language that neglects the possible existence of worlds that offer more benign environments to life than Earth does. We call these objects "superhabitable" and discuss in which contexts this term could be used, that is to say, which worlds tend to be more habitable than Earth. In an appendix, we show why the principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like. Superhabitable worlds must be considered for future follow-up observations of signs of extraterrestrial life. Considering a range of physical effects, we conclude that they will tend to be slightly older and more massive than Earth and that their host star...

  13. Transnational Class Formation? Globalization and the Canadian Corporate Network

    Directory of Open Access Journals (Sweden)

    Jerome Klassen

    2015-08-01

    Full Text Available The issue of transnational class formation has figured centrally in recent debates on globalization. These debates revolve around the question of whether or not new patterns of cross-border trade and investment have established global circuits of capital out of which a transnational capitalist class has emerged. This paper takes up the notion of transnational class formation at the point of corporate directorship interlocks. Using Canada as a case study, it maps the changing network of directorship interlocks between leading firms in Canada and the world economy. In particular, the paper examines the role of transnational corporations (TNCs in the Canadian corporate network; the resilience of a national corporate community; and new patterns of cross-border interlocking amongst transnational firms. Through this empirical mapping, the paper finds a definite link between investment and interlocking shaping the social space of the global corporate elite. Corporations with a transnational base of accumulation tend to participate in transnational interlocking. While national corporate communities have not been transcended, transnational firms increasingly predominate within them, articulating national with transnational elite segments. This new network of firms reconstitutes the corporate power bloc and forms a nascent transnational capitalist class.

    Militarism is a rapidly growing factor in that complex network of social, political and economic causes of ill health among the world's poor. This complex of causes is driving a spiral of class inequality, political instability, and military repression in many less developed nations. These nations share a uniform security doctrine, which has major health impacts. Here five impacts are noted: diversion of resources, suppression of dissent, military classism, environment damage, and crime and terrorism. The demand stimulated by the recent Persian Gulf War for expensive, high-technology weapons may deepen Third World debt and fuel the cycle of poverty, ill health, social unrest, and military oppression. International health workers need to take account of the causes and effects of militarism in their studies of health problems. Their work could be aided by organizations that promote disarmament and environment preservation.

In this paper, the effect of attending an MA class during grades 4-6 on students' cognitive skills is estimated. Using a unique…

  7. Class distinction

    Science.gov (United States)

    White, M. Catherine

    Typical 101 courses discourage many students from pursuing higher level science and math courses. Introductory classes in science and math serve largely as a filter, screening out all but the most promising students, and leaving the majority of college graduates—including most prospective teachers—with little understanding of how science works, according to a study conducted for the National Science Foundation. Because few teachers, particularly at the elementary level, experience any collegiate science teaching that stresses skills of inquiry and investigation, they simply never learn to use those methods in their teaching, the report states.

    After World WarⅡ, the Allies made an imposed democratization reform in Germany for permanent erasing German threat to the peace of the world. Although the Allies made Germany a mandatory transformation, but later on the democratization of the federal republic in Germany plays an important enlightening role, which laid a foundation for the later re-education. Germany made the democratic transformation in a variety of forms, and its history classroom education is one aspect of democratization reforms. Not only the Germans themselves face up to history, to reflect on war crimes, and they also educate their teenagers to correctly understand the history of world warⅡ, understand the truth of hi story, bear the evils of war, hate war and love peace. German people’s thorough understanding of the history of World WarⅡhas made the world understanding and trust. W hile the Japanese government and the right try to cover up the historical truth of aggression, tamper with the history textbook, fool and deceive the world.%二战后,盟国为了永远消除德国对世界和平的威胁,对其进行了一场强制性的民主化改造。虽然盟国对战败德国的改造带有强制性,但对后来联邦德国的民主化以及文化的发展起了重要的启蒙作用,为后来的历史反思、思想文化方面的再教育奠定了基础。德国民众进行民主化改造、反思历史方面的教育是多样的,历史课堂教育就是其中一个方面。德国人不仅自身正视历史、反思战争罪行,而且也教育青少年正确认识二战历史,了解历史的真相,承担战争的罪责,培养青少年痛恨战争、热爱和平的观念。德国人民对二战的历史认识比较彻底,取得了世人的谅解和信任;而日本政府及右翼势力则竭力掩盖侵略历史真相,篡改历史教科书,愚弄、欺骗世人。

    2011-05-01

    The Harvard-Smithsonian Center for Astrophysics is developing a two-to-three week NSF-funded program for middle and high school students using telescope-based investigations of real world cutting edge scientific questions. The goal is to reveal and enhance students' understanding of core concepts in the physical sciences as well as to develop their proficiency in the practice of scientific inquiry. Specifically, students and teachers are joining scientists in the search for habitable worlds by exploring transiting exoplanets. Using robotic telescopes, image processing software and simulations, students take images and then measure the brightness of their target star to create a portrait of a transiting planet including how large it is; the tilt of its orbit; how far it is from its star and what its environment might be like. Once classes collect and analyze their own data, they can begin to compare, combine, and communicate their findings with others in the community. Interactive models help students predict what they might expect to find and interpret what they do find. During the past two years, the Center for Astrophysics has tested the concept in fifty middle-and high-school classrooms, enrichment classes and after school science clubs in 13 states across the United States. To date, astronomy, earth science, and physics students have successfully detected Jupiter-sized planets transiting stars such as TRES-3, HATP-10, and HATP-12. Preliminary results indicate that learning of core concept did occur. Gains in content were most significant in middle school students as this project delivered new information to them while it served primarily as a review of concepts and application of skills for advanced placement classes. A significant change also occurred in students’ self reported knowledge of exoplanets. There was also an increase in students’ awareness of exoplanets and attitudes about science after participating in this project.

    1994-01-01

    Introduction In China, some English teachers go to class with only a textbook and a teaching plan, nothing else. After a while, the students complain that their classes are becoming more and more boring. Teachers have tried many ways to make their classes more interesting, motivating and effective, but using pictures in the classroom to do this has not been a popular method. The world provides us with all kinds of beautiful pictures. There is no reason why we should not make better use of them in language learning and teaching. This article will discuss the reasons for using pictures, suggest ways of collecting pictures and ways of using pictures in reading, writing, listening and speaking classes.

  13. Context-sensitive intra-class clustering

    KAUST Repository

    Yu, Yingwei

    2014-02-01

    This paper describes a new semi-supervised learning algorithm for intra-class clustering (ICC). ICC partitions each class into sub-classes in order to minimize overlap across clusters from different classes. This is achieved by allowing partitioning of a certain class to be assisted by data points from other classes in a context-dependent fashion. The result is that overlap across sub-classes (both within- and across class) is greatly reduced. ICC is particularly useful when combined with algorithms that assume that each class has a unimodal Gaussian distribution (e.g., Linear Discriminant Analysis (LDA), quadratic classifiers), an assumption that is not always true in many real-world situations. ICC can help partition non-Gaussian, multimodal distributions to overcome such a problem. In this sense, ICC works as a preprocessor. Experiments with our ICC algorithm on synthetic data sets and real-world data sets indicated that it can significantly improve the performance of LDA and quadratic classifiers. We expect our approach to be applicable to a broader class of pattern recognition problems where class-conditional densities are significantly non-Gaussian or multi-modal. © 2013 Elsevier Ltd.

    (Abstract only) New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth was mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing, scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1-5, following the AAVSO/AAS meetings. World Science Festival was founded by Dr. Brian Greene, Columbia University, and is operated through the World Science Foundation. The Festival is "saturation science" all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in "science" venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend from hard science, with lectures like those by us astronomers, to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee. While almost all events are on Manhattan, effort has been made to geographically disperse them, even to the outer boroughs. The grand finale of World Science Festival is a street fair in Washington Square. Science centers in booths, tents, and pavilions highlight their work. In past years this fair drew 100,000 to 150,000 visitors. The entire Festival attracts about a quarter-million attendees. NYSkies is a proud participant at the Washington Square fair. It interprets the "Earth to the Universe" display, debuting during IYA-2009. Attendance at "Earth..." on just the day of the fair plausibly is half of all visitors in America. The presentation shows the scale and scope of World Science Festival, its relation to the City, and how our astronomers work with it.

    Full Text Available 過去二、三十年間,在教育及工作領域中,各有一些重要的跨國共通發展趨勢,且經常與全球化下的國際競爭有關。 在教育領域上,全球化帶來的國家競爭壓力、各國政府對人力資本的重視、國際組織的影響(如經濟合作暨發展組織(Organization for Economic Cooperation and Development, OECD)、世界銀行(World Bank)、聯合國教科文組織(United Nations Education Scientific and Cultural Organization, UNESCO))等各種因素之交乘影響,直接或間接造成了國際教育評比的興起及盛行。國際學生能力評量計畫(Programme for International Student Assessment, PISA)與國際數學與科學教育成就趨勢調查(Trends in Mathematics and Science Study, TIMSS)即為目前最知名且定期執行的國際教育評比,此類教育評比通常是以紙筆或電腦測驗的形式,每隔三或四年,針對國中或國小學生,進行數學、科學、閱讀等科目的標準化測驗,最後公布測驗結果及相關分析,為各國教育品質及教育均等提供跨國比較及跨時趨勢的評估。 將學生測驗成果視為未來國家競爭力的政府官員及學者並不在少數,因此,這類國際教育評比的結果對「表現不佳」的國家通常會造成壓力,進而影響到各國教育政策的方向及課程內容的調整。從表面上看,各國政府重視人力培育,此現象似乎很難說是件壞事,不過,有部分教育學者認為此類跨國執行的統一標準化測驗,會導致全球學校教育的同質化,喪失在地性與多元性(Spring, 2008)。 另一方面,勞動力市場也有一些具有跨國共通性的發展趨勢。以往在經濟發展的進程中,曾因企業大型化而逐漸減少的自營與創業活動,於過去20年間又再度興盛。1產業結構變遷(服務業部門擴大)、消費市場分殊且多元、知識經濟的

    The national Italian cross-country ski team has been evaluated on the basis of a new double poling cross-country roller skiing incremental test to exhaustion (DP) on a motorized driven treadmill. To verify the capacity of this specific test to predict performance, peak oxygen uptake (VO2peak), oxygen uptake at anaerobic threshold (VO2Th), peak treadmill speed, and treadmill speed at anaerobic threshold (Speak and STh, respectively) were measured during the test and correlated with the level of performance of 10 world class Italian female cross-country skiers. The physiological data obtained were also compared with results of an incremental and maximal test carried out by the same athletes but with the diagonal stride (DS) technique. Peak heart rate (HRpeak), HRTh, and VO2Th were significantly higher during DS than during DP (p cross-country skiers' performance.

  4. Class categories and the subjective dimension of class: the case of Denmark.

    Harrits, Gitte Sommer; Pedersen, Helene Helboe

    2017-09-15

    Class relations have been proven to affect various aspects of social life, even in modern individualized societies. However, following claims on individualization and the so-called 'death of class' thesis, studying the subjective dimension of class - that is, the way individuals perceive of class relations and their own position within them - has gone out of style. We argue that even in equalized societies, subjective class perceptions may still influence attitudes and behaviour as they evolve to fit modern class relations. To explore the existence as well as structure and content of perceived social classes, this article investigates how people describe society and social groups in focus group discussions. We find that groups in different positions in terms of education and economy all tend to apply hierarchical class categories to describe Danish society, which is normally seen as one of the most equal societies and political systems in the world. In addition, we find that economic resources serve as a baseline for the hierarchical ordering, often supplemented with notions of education, lifestyle and/or occupational profile. Even though people are somewhat uncomfortable with the notion of class, their descriptions of Danish society and classes are surprisingly similar within and across groups. We conclude that not only do class relations matter; people are also highly aware of the existing classes and able to position themselves and others according to their notion of classes. © London School of Economics and Political Science 2017.

    Science.gov (United States)

    Kraus, Michael W; Keltner, Dacher

    2013-08-01

    Recent evidence suggests that perceptions of social class rank influence a variety of social cognitive tendencies, from patterns of causal attribution to moral judgment. In the present studies we tested the hypotheses that upper-class rank individuals would be more likely to endorse essentialist lay theories of social class categories (i.e., that social class is founded in genetically based, biological differences) than would lower-class rank individuals and that these beliefs would decrease support for restorative justice--which seeks to rehabilitate offenders, rather than punish unlawful action. Across studies, higher social class rank was associated with increased essentialism of social class categories (Studies 1, 2, and 4) and decreased support for restorative justice (Study 4). Moreover, manipulated essentialist beliefs decreased preferences for restorative justice (Study 3), and the association between social class rank and class-based essentialist theories was explained by the tendency to endorse beliefs in a just world (Study 2). Implications for how class-based essentialist beliefs potentially constrain social opportunity and mobility are discussed.

The height and body mass (BM distribution of sprinters (42 men and 44 women were statistically compared to the distributions of American and Danish normal populations. The main results showed that there was significantly less BM and height variability (measured as standard deviation among male sprinters than among the normal male population (US and Danish, while female sprinters showed less BM variability than the US and Danish normal female populations. On average the American normal population was shorter than the sprinters. There was no height difference between the sprinters and the Danish normal population. All female groups had similar height variability. Both male and female sprinters had lower body mass index (BMI than the normal populations. It is likely that there is no single optimal height for sprinters, but instead there is an optimum range that differs for males and females. This range in height appears to exclude people who are very tall or very short in stature. Sprinters are generally lighter in BM than normal populations. Also, the BM variation among sprinters is less than the variation among normal populations. These anthropometric characteristics typical of sprinters might be explained, in part, by the influence the anthropometric characteristics have on relative muscle strength and step length

    The currently known food allergens are assigned to a relatively small number of protein families. Food allergens grouped into protein families share common functional and structural features that can be attributed to the allergenic potency and potential cross-reactivity of certain proteins. Molecular data, in terms of structural information, biochemical characteristics and clinical relevance for each known allergen, including isoforms and variants, are mainly compiled into four open-access databases. Allergens are designated according to defined criteria by the World Health Organization and the International Union of Immunological Societies Allergen Nomenclature Sub-committee. Food allergies are caused by primary sensitisation to the disease-eliciting food allergens (class I food allergen), or they can be elicited as a consequence of a primary sensitisation to inhalant allergens and subsequent IgE cross-reaction to homologous proteins in food (class II food allergens). Class I and class II allergens display different clinical significance in children and adults and are characterised by different molecular features. In line with this, high stability when exposed to gastrointestinal digestion and heat treatment is attributed to many class I food allergens that frequently induce severe reactions. The stability of a food allergen is determined by its molecular characteristics and can be influenced by structural (chemical) modifications due to thermal processing. Moreover, the immunogenicity and allergenicity of food allergens further depends on specific T cell and B cell epitopes. Although the T cell epitope pattern can be highly diverse for individual patients, several immuno-prominent T cell epitopes have been identified. Such conserved T cell epitopes and IgE cross-reactive B cell epitopes contribute to cross-reactivity between food allergens of the same family and to clinical cross-reactivity, similar to the birch pollen-food syndrome.

    Adaptive synchronization in NW small-world dynamical networks was studied. Firstly, an adaptive synchronization method is presented and explained. Then, it is applied to two different classes of dynamical networks,one is a class-B network, small-world connected R(o)ssler oscillators, the other is a class-A network, small-world connected Chua's circuits. The simulation verifies the validity of the presented method. It also shows that the adaptive synchronization method is robust to the variations of the node systems parameters. So the presented method can be used in networks whose node systems have unknown or time-varying parameters.

  7. Hierarchical Maximum Margin Learning for Multi-Class Classification

    2012-01-01

    Due to myriads of classes, designing accurate and efficient classifiers becomes very challenging for multi-class classification. Recent research has shown that class structure learning can greatly facilitate multi-class learning. In this paper, we propose a novel method to learn the class structure for multi-class classification problems. The class structure is assumed to be a binary hierarchical tree. To learn such a tree, we propose a maximum separating margin method to determine the child nodes of any internal node. The proposed method ensures that two classgroups represented by any two sibling nodes are most separable. In the experiments, we evaluate the accuracy and efficiency of the proposed method over other multi-class classification methods on real world large-scale problems. The results show that the proposed method outperforms benchmark methods in terms of accuracy for most datasets and performs comparably with other class structure learning methods in terms of efficiency for all datasets.

    Arenaviruses cause severe human disease ranging from aseptic meningitis following lymphocytic choriomeningitis virus (LCMV) infection to hemorrhagic fever syndromes following infection with Guanarito virus (GTOV), Junin virus (JUNV), Lassa virus (LASV), Machupo virus (MACV), Sabia virus (SABV), or Whitewater Arroyo virus (WWAV). Cellular immunity, chiefly the CD8(+) T-cell response, plays a critical role in providing protective immunity following infection with the Old World arenaviruses LASV and LCMV. In the current study, we evaluated whether HLA class I-restricted epitopes that are cross-reactive among pathogenic arenaviruses could be identified for the purpose of developing an epitope-based vaccination approach that would cross-protect against multiple arenaviruses. We were able to identify a panel of HLA-A*0201-restricted peptides derived from the same region of the glycoprotein precursor (GPC) of LASV (GPC spanning residues 441 to 449 [GPC(441-449)]), LCMV (GPC(447-455)), JUNV (GPC(429-437)), MACV (GPC(444-452)), GTOV (GPC(427-435)), and WWAV (GPC(428-436)) that displayed high-affinity binding to HLA-A*0201 and were recognized by CD8(+) T cells in a cross-reactive manner following LCMV infection or peptide immunization of HLA-A*0201 transgenic mice. Immunization of HLA-A*0201 mice with the Old World peptide LASV GPC(441-449) or LCMV GPC(447-455) induced high-avidity CD8(+) T-cell responses that were able to kill syngeneic target cells pulsed with either LASV GPC(441-449) or LCMV GPC(447-455) in vivo and provided significant protection against viral challenge with LCMV. Through this study, we have demonstrated that HLA class I-restricted, cross-reactive epitopes exist among diverse arenaviruses and that individual epitopes can be utilized as effective vaccine determinants for multiple pathogenic arenaviruses.

    Controlling complex networks is of vital importance in science and engineering. Meanwhile, local-world effect is an important ingredient which should be taken into consideration in the complete description of real-world complex systems. In this letter, structural controllability of a class of local-world networks is investigated. Through extensive numerical simulations, firstly, effects of local world size M and network size N on structural controllability are examined. For local-world networks with sparse topological configuration, compared to network size, local-world size can induce stronger influence on controllability, however, for dense networks, controllability is greatly affected by network size and local-world effect can be neglected. Secondly, relationships between controllability and topological properties are analyzed. Lastly, the robustness of local-world networks under targeted attacks regarding structural controllability is discussed. These results can help to deepen the understanding of structural complexity and connectivity patterns of complex systems. - Highlights: • Structural controllability of a class of local-world networks is investigated. • For sparse local-world networks, compared to network size, local-world size can bring stronger influence on controllability. • For dense networks, controllability is greatly affected by network size and the effect of local-world size can be neglected. • Structural controllability against targeted node attacks is discussed.

For example, the faculty member who loves punk rock has an opportunity, through hairstyle and attire choices in the virtual world, to share that part of herself with students. However, deciding to share that part of the self can depend on a number of factors: departmental guidelines, ideas of professionalism, privacy concerns, or the need for separation between the in-class self and the out-of-class self. In my study on faculty in virtual worlds, I examined faculty members’ perspectives on recreating and being themselves in immersive virtual environments.

    Class network routing is implemented in a network such as a computer network comprising a plurality of parallel compute processors at nodes thereof. Class network routing allows a compute processor to broadcast a message to a range (one or more) of other compute processors in the computer network, such as processors in a column or a row. Normally this type of operation requires a separate message to be sent to each processor. With class network routing pursuant to the invention, a single message is sufficient, which generally reduces the total number of messages in the network as well as the latency to do a broadcast. Class network routing is also applied to dense matrix inversion algorithms on distributed memory parallel supercomputers with hardware class function (multicast) capability. This is achieved by exploiting the fact that the communication patterns of dense matrix inversion can be served by hardware class functions, which results in faster execution times.

    A large body of research in Western cultures has demonstrated the psychological and health effects of social class. This review outlines a cultural psychological approach to social stratification by comparing psychological and health manifestations of social class across Western and East Asian cultures. These comparisons suggest that cultural meaning systems shape how people make meaning and respond to material/structural conditions associated with social class, thereby leading to culturally divergent manifestations of social class. Specifically, unlike their counterparts in Western cultures, individuals of high social class in East Asian cultures tend to show high conformity and other-orientated psychological attributes. In addition, cultures differ in how social class impacts health (i.e. on which bases, through which pathways, and to what extent). Copyright © 2017 Elsevier Ltd. All rights reserved.

    2002-09-01

    By stimulating commerce and development at the bottom of the economic pyramid, multi-nationals could radically improve the lives of billions of people and help create a more stable, less dangerous world. Achieving this goal does not require MNCs to spearhead global social-development initiatives for charitable purposes. They need only act in their own self-interest. How? The authors lay out the business case for entering the world's poorest markets. Fully 65% of the world's population earns less than $2,000 per year--that's 4 billion people. But despite the vastness of this market, it remains largely untapped. The reluctance to invest is easy to understand, but it is, by and large, based on outdated assumptions of the developing world. While individual incomes may be low, the aggregate buying power of poor communities is actually quite large, representing a substantial market in many countries for what some might consider luxury goods like satellite television and phone services. Prices, and margins, are often much higher in poor neighborhoods than in their middle-class counterparts. And new technologies are already steadily reducing the effects of corruption, illiteracy, inadequate infrastructure, and other such barriers. Because these markets are in the earliest stages of economic development, revenue growth for multi-nationals entering them can be extremely rapid. MNCs can also lower costs, not only through low-cost labor but by transferring operating efficiencies and innovations developed to serve their existing operations. Certainly, succeeding in such markets requires MNCs to think creatively. The biggest change, though, has to come from executives: Unless business leaders confront their own preconceptions--particularly about the value of high-volume, low-margin businesses--companies are unlikely to master the challenges or reap the rewards of these developing markets.

  4. Closed World Assumption for Disjunctive Reasoning

    WANG Kewen; ZHOU Lizhu

    2001-01-01

    In this paper, the relationship between argumentation and closed world reasoning for disjunctive information is studied. In particular, the authors propose a simple and intuitive generalization of the closed world assumption (CWA) for general disjunctive deductive databases (with default negation). This semantics,called DCWA, allows a natural argumentation-based interpretation and can be used to represent reasoning for disjunctive information. We compare DCWA with GCWA and prove that DCWA extends Minker's GCWA to the class of disjunctive databases with default negation. Also we compare our semantics with some related approaches.In addition, the computational complexity of DCWA is investigated.

  12. Class II Microcins

    Vassiliadis, Gaëlle; Destoumieux-Garzón, Delphine; Peduzzi, Jean

    Class II microcins are 4.9- to 8.9-kDa polypeptides produced by and active against enterobacteria. They are classified into two subfamilies according to their structure and their gene cluster arrangement. While class IIa microcins undergo no posttranslational modification, class IIb microcins show a conserved C-terminal sequence that carries a salmochelin-like siderophore motif as a posttranslational modification. Aside from this C-terminal end, which is the signature of class IIb microcins, some sequence similarities can be observed within and between class II subclasses, suggesting the existence of common ancestors. Their mechanisms of action are still under investigation, but several class II microcins use inner membrane proteins as cellular targets, and some of them are membrane-active. Like group B colicins, many, if not all, class II microcins are TonB- and energy-dependent and use catecholate siderophore receptors for recognition/­translocation across the outer membrane. In that context, class IIb microcins are considered to have developed molecular mimicry to increase their affinity for their outer membrane receptors through their salmochelin-like posttranslational modification.

  3. Topological structural classes of complex networks

    Science.gov (United States)

    Estrada, Ernesto

    2007-01-01

    We use theoretical principles to study how complex networks are topologically organized at large scale. Using spectral graph theory we predict the existence of four different topological structural classes of networks. These classes correspond, respectively, to highly homogenous networks lacking structural bottlenecks, networks organized into highly interconnected modules with low inter-community connectivity, networks with a highly connected central core surrounded by a sparser periphery, and networks displaying a combination of highly connected groups (quasicliques) and groups of nodes partitioned into disjoint subsets (quasibipartites). Here we show by means of the spectral scaling method that these classes really exist in real-world ecological, biological, informational, technological, and social networks. We show that neither of three network growth mechanisms—random with uniform distribution, preferential attachment, and random with the same degree sequence as real network—is able to reproduce the four structural classes of complex networks. These models reproduce two of the network classes as a function of the average degree but completely fail in reproducing the other two classes of networks.

  10. The Elusive New Middle Class in Brazil

    2015-12-01

    Full Text Available Against the background of the generalized reduction of poverty in the world, and particularly in Brazil, this article intends to gauge the socio-economic profile of Brazilian households that emerged from poverty and have been identified as integrating a "new middle class". Using indicators of standards of living from the 2008-2009 Survey on Family Budgets (POF/IBGE, we found out that, in contrast to what has been assumed on the basis of average income criteria, this social stratum is markedly heterogeneous, most of it being similar in their consumption patterns to the economically vulnerable or outright poor strata. So, we conclude that, from a sociological perspective that demands additional conditions besides income levels to identify social classes, it is a category mistake to call this social stratum a new middle class. We conjecture that this may be consequential in terms of policy priorities and choices.

    Spanish women live almost 2 times longer today than did their great grandmothers (60-65 years vs. 35). Contraception is more accessible, resulting in fewer pregnancies and their complications. The National Health Service of Spain provides women and their families medical care. Yet, women's health risks continue. Class, race, and geography result in women having uneven access to medical care. Primary health care services are not a priority as are high- technology hospitals. Women, who already lead a busy life, still care for older people or people with disabilities. Many households have a very limited or no income and depend on welfare benefits or family. There are more women than men who are poor because women, many of whom are single, are raising large families and many live alone. Women are often the victims of violence and of domestic abuse (1993, 86 violent deaths and 200,000 cases of abuse by a partner). Spain has laws that protect women facing divorce and that allow abortion, but men have created the world order. Women suffer daily in a world which does not recognize rape and sexual harassment as war crimes (e.g., former Yugoslavia). In Seville, the Solidarity Network of Women in Black is a pacifist group working to stop violence. They plan on setting up links to publicly denounce and act against all aggression and to institutionalize women's right to full freedom. War is destroying women's lives.

    Full Text Available The CIA World Factbook is a prime example of a curated database – a database that is constructed and maintained with a great deal of human effort in collecting, verifying, and annotating data. Preservation of old versions of the Factbook is important for verification of citations; it is also essential for anyone interested in the history of the data such as demographic change. Although the Factbook has been published, both physically and electronically, only for the past 30 years, we appear in danger of losing this history. This paper investigates the issues involved in capturing the history of an evolving database and its application to the CIA World Factbook. In particular it shows that there is substantial added value to be gained by preserving databases in such a way that questions about the change in data, (longitudinal queries can be readily answered. Within this paper, we describe techniques for recording change in a curated database and we describe novel techniques for querying the change. Using the example of this archived curated database, we discuss the extent to which the accepted practices and terminology of archiving, curation and digital preservation apply to this important class of digital artefacts.

    Full Text Available Virtual property theft is a serious problem that exists in virtual worlds. Legitimate users of these worlds invest considerable amounts of time, effort and real-world money into obtaining virtual property, but unfortunately, are becoming victims of theft in high numbers. It is reported that there are over 1 billion registered users of virtual worlds containing virtual property items worth an estimated US$50 billion dollars. The problem of virtual property theft is complex, involving many legal, social and technological issues. The software used to access virtual worlds is of great importance as they form the primary interface to these worlds and as such the primary interface to conduct virtual property theft. The security vulnerabilities of virtual world applications have not, to date, been examined. This study aims to use the process of software inspection to discover security vulnerabilities that may exist within virtual world software – vulnerabilities that enable virtual property theft to occur. Analyzing three well know virtual world applications World of Warcraft, Guild Wars and Entropia Universe, this research utilized security analysis tools and scenario testing with focus on authentication, trading, intruder detection and virtual property recovery. It was discovered that all three examples were susceptible to keylogging, mail and direct trade methods were the most likely method for transferring stolen items, intrusion detection is of critical concern to all VWEs tested, stolen items were unable to be recovered in all cases and lastly occurrences of theft were undetectable in all cases. The results gained in this study present the key problem areas which need to be addressed to improve security and reduce the occurrence of virtual property theft.

    The Small-World Network on a Sphere SWNS is a non-crossing network that has no hubs and presents the small-world property diam log N with diam being the maximal distance between any two vertices and N being the number of vertices. The SWNS is constructed using a partition of the sphere and the parallels are regular sections of the sphere with constant latitude. The number of cells on the parallels, however, increases exponentially from the pole to the equator of the sphere. We analytically compute the distribution of connectivity, the clustering coefficient and the SWNS distances. The resilience of the model against selective attacks is also discussed.

    Many studies have reported a social class gradient within overweight prevalence ( 1-4 ). Additionally, cross-country comparisons report high overweight trends and a change in food consumption patterns in countries affected by an economic crisis ( 5-11 ). The aim of this study was to assess the association between social class and recession on obesity levels in 3-year-old Irish children. The population-based infant cohort of the national Growing Up in Ireland (GUI) study was used. Prevalence rates of overweight and obesity were calculated and logistic regression models, adjusting for confounders, were used to examine the relationship between social class, effects of the recession and childhood obesity. In 2008, 19.5% of 9-month-olds were obese and 19.4% overweight increasing to 22.7% and 20.4%, respectively by 2011 when the infants were 3 years old (World Health Organization (WHO) criteria). The prevalence of obesity increased by 2.3% to 10.1% for various social classes (unadjusted). However, adjusting for confounders, there was no evidence of a difference in obesity of 3-year-old children across social classes. There was evidence that obesity was 22-27% higher for families who perceived a very significant crisis effect on their family, compared with those significantly affected. Increases in obesity were found to be significantly associated with perceived recession effects on the family, but not with social class. Policy makers should be aware that in times of economic downturn, public health efforts to promote healthy weight are needed at a population level rather than for specific social classes.

  2. The ubiquity of small-world networks

    CERN Document Server

    Telesford, Qawi K; Hayasaka, Satoru; Burdette, Jonathan H; Laurienti, Paul J

    2011-01-01

    Small-world networks by Watts and Strogatz are a class of networks that are highly clustered, like regular lattices, yet have small characteristic path lengths, like random graphs. These characteristics result in networks with unique properties of regional specialization with efficient information transfer. Social networks are intuitive examples of this organization with cliques or clusters of friends being interconnected, but each person is really only 5-6 people away from anyone else. While this qualitative definition has prevailed in network science theory, in application, the standard quantitative application is to compare path length (a surrogate measure of distributed processing) and clustering (a surrogate measure of regional specialization) to an equivalent random network. It is demonstrated here that comparing network clustering to that of a random network can result in aberrant findings and networks once thought to exhibit small-world properties may not. We propose a new small-world metric, {\\omega}...

    In order to use gravity anomalies in geodetic computations and geophysical interpretations, the observed gravity values from which anomalies are derived should be referred to one consistent world wide system. The International Gravity Standardization Net 1971 was adapted by the International Union of Geodesy and Geophysics at Moscow in 1971, the network was result of extensive cooperation by many organizations and individuals around the world. The network contains more than 1800 stations around the world. The data used in the adjustment included more than 25,000 gravimetry, pendulum and absolute measurements.

Findings show that public spheres characterised by collectivism, poverty and/or marginalisation: a) accelerate decentration bringing the public world and its complexity to the foreground of children’s depictions, and b) show a strong link between self and the public...

  14. A Typology of Ethnographic Scales for Virtual Worlds

    Science.gov (United States)

    Boellstorff, Tom

    This chapter outlines a typology of genres of ethnographic research with regard to virtual worlds, informed by extensive research the author has completed both in Second Life and in Indonesia. It begins by identifying four confusions about virtual worlds: they are not games, they need not be graphical or even visual, they are not mass media, and they need not be defined in terms of escapist role-playing. A three-part typology of methods for ethnographic research in virtual worlds focuses on the relationship between research design and ethnographic scale. One class of methods for researching virtual worlds with regard to ethnographic scale explores interfaces between virtual worlds and the actual world, whereas a second examines interfaces between two or more virtual worlds. The third class involves studying a single virtual world in its own terms. Recognizing that all three approaches have merit for particular research purposes, ethnography of virtual worlds can be a vibrant field of research, contributing to central debates about human selfhood and sociality.

    The RATAN-600 new-technology telescope (NTT), which supplies about one-quarter of the observational material in Russia in the field of radio astronomy and more than 80 percent in the central, centimeter-decimeter range, is described. The RATAN-600 is the first multielement reflector radio telescope without any structure linking the surface elements. The functions normally performed by such structure are executed by the earth's surface. It is also the first radio telescope with a controlled-shape surface. In observations at different elevations about the horizon, the shape of its surface varies, remaining in the family of second-order surfaces. The RATAN-600 is also the first aperture-synthesis reflector-type telescope. The location of the radio telescope, its design, its modes of operation, and its future prospects are discussed.

  5. IS THE WORLD FLAT?

    Directory of Open Access Journals (Sweden)

    Cristian Încalţărău

    2010-06-01

    Full Text Available Globalization became more and more prominent during the last decades. There is no way to argue that globalization led to more interconnected economies, facilitating the communication and the collaboration around the world. But where is this going? Doesglobalization mean uniformity or diversity? As the world begins to resemble more, the people are trying to distinguish between them more, which can exacerbate nationalistic feeling. Friedman argues that globalization made the world smaller and flatter, allowing all countries to take chance of the available opportunities equally. But is this really true? Although politic and cultural factors can stand in front of a really flat world, what is the key for Chinese and Indian success and which are theirs perspectives?

    2004-01-01

    We consider a brane world and its gravitational linear perturbations. We present a general solution of the perturbations in the bulk and find the complete perturbed junction conditions for generic brane dynamics. We also prove that (spin 2) gravitational waves in the great majority of cases can only arise in connection with a non-vanishing anisotropic stress. This has far reaching consequences for inflation in the brane world. Moreover, contrary to the case of the radion, perturbations are stable.

    Virtual reality has an increasingly significant role to play in teaching and research, but for geological applications realistic landscapes are required that contain sufficient detail to prove viable for investigation by both inquisitive students and critical researchers. To create such virtual landscapes, we combine DTM data with digitally modelled outcrops in the game engine Unity. Our current landscapes are fictional worlds, invented to focus on generation techniques and the strategic and spatial immersion within a digital environment. These have proved very successful in undergraduate teaching; however, we are now moving onto recreating real landscapes for more advanced teaching and research. The first of these is focussed on Rhoscolyn, situated within the Ynys Mon Geopark on Anglesey, UK. It is a popular area for both teaching and research in structural geology so has a wide usage demographic. The base of the model is created from DTM data, both 1 m LiDAR and 5 m GPS point data, and manipulated with QGIS before import to Unity. Substance is added to the world via models of architectural elements (e.g. walls and buildings) and appropriate flora and fauna, including sounds. Texturing of these models is performed using 25 cm aerial imagery and field photographs. Whilst such elements enhance immersion, it is the use of digital outcrop models that fully completes the experience. From fieldwork, we have a library of photogrammetric outcrops that can be modelled into 3D features using free (VisualSFM and MeshLab) and non-free (AgiSoft Photoscan) tools. These models are then refined and converted in Maya to create models for better insertion into the Unity environment. The finished product is a virtual landscape; a Rhoscolyn `world' that is sufficiently detailed to provide a base not only for geological teaching and training but also for geological research. Additionally, the `Rhoscolyn World' represents a significant tool for those students who are unable to attend

    Full Text Available We extend F. Holland's definition of the space of resonant classes of functions, on the real line, to the space R(Φpq (1≦p, q≦∞ of resonant classes of measures, on locally compact abelian groups. We characterize this space in terms of transformable measures and establish a realatlonship between R(Φpq and the set of positive definite functions for amalgam spaces. As a consequence we answer the conjecture posed by L. Argabright and J. Gil de Lamadrid in their work on Fourier analysis of unbounded measures.
