Resource allocation to documents departments in academic libraries is not a purely rational process. This lack of rationality leads to wide variation in the local levels of support upon which the GPO depository system depends. This article demonstrates these variations and suggests how documents librarians may change the levels of support their departments receive from sources within and beyond their libraries. 相似文献

In developing countries, the trend has been for government to assume gradual control of schools run by religious organisations, while allowing them to retain their religious affiliation. In the Caribbean, the relationship between church and state educational systems has generally been cordial. This is particularly so in Trinidad and Tobago, where almost three quarters of the primary schools are denominational: Roman Catholic, other Christian, Hindu and Muslim. However, a significant proportion of pupils do not adhere to the host faith. Demographic trends and internal migration have disturbed the previous pattern of population, but the most important factor is the influence of the Common Entrance Examination, which controls entry to secondary education. Certain primary schools achieve high pass rates and attract large numbers of applicants from all sectors of society, while School Boards and principals accept over-population and set entry criteria other than religious affiliation. Variation in curricula is limited by recently drafted requirements, the government provides the bulk of school funds, and regularly inspects all schools. Such controls may enable the present government to fulfil its intention of deemphasising the Common Entrance Examination, but it thereby runs the risk of endangering the religious tolerance engendered by the present multidenominational nature of religious schools.
Zusammenfassung In Entwicklungsländern ging das Bestreben der Regierung dahin, allmählich die Kontrolle über die von religiösen Organisationen geführten Schulen zu übernehmen und ihnen dabei ihre religiöse Bindung zu belassen. In der Karibik bestand bisher im allgemeinen ein herzliches Verhätnis zwischen Kirche und staatlichen Erziehungseinrichtungen. Dies gilt besonders für Trinidad und Tobago, wo fast drei Viertel der Grundschulen Konfessionsschulen sind: römisch-katholisch, anderweitig christlich, hinduistisch und moslemisch. Eine große Anzahl von Schülern gehört allerdings nicht der Glaubensrichtung der Schule an. Demografische Trends und Bevölkerungsfluktuation haben frühere Bevölkerungsmuster verändert, aber der wichtigste Punkt ist der Einfluß der allgemeinen Aufnahmeprüfung, die den Eintritt in die weiterführenden Schulen reguliert.Einige Grundschulen haben hohe Erfolgsraten und ziehen dadurch viele Bewerber aus allen Gesellschaftsschichten an, wobei Schulbehörden und Schulleiter eine Überbelegung akzeptieren und andere Aufnahmekriterien als religiöse Zugehörigkeit festsetzen. Änderungsmöglichkeiten im Curriculum sind durch kürzlich herausgegebene Anforderungsrichtlinien eingeschränkt; die Regierung zahlt den größten Teil der Schulmittel und inspiziert regelmäßig alle Schulen. Diese Kontrollen mögen es zwar der gegenwärtigen Regierung ermöglichen, ihre Absicht, die Bedeutung der allgemeinen Aufnahmeprüfung zu schwächen, zu verwirklichen, aber sie riskiert gleichzeitig, die durch die gegenwärtigen multikonfessionellen Religionsschulen ausgelöste religiöse Toleranz zu gefährden.
Résumé Dans les pays en développement, le gouvernement assume habituellement le contrôle continu des écoles régies par les organisations religieuses, tout en leur permettant de conserver leur adhésion religieuse. Aux Caraïbes, la relation entre les systèmes éducatifs publics et religieux est généralement cordiale. C'est particulièrement le cas à Trinité-et-Tobago, où presque les trois quarts des écoles primaires sont des écoles confessionnelles: catholiques romaines, diverses écoles chrétiennes, écoles hindoues et musulmanes. Cependant, un nombre important d'élèves n'adhère pas à la religion de l'école. Les tendances démographiques et la migration interne ont changé l'ancienne structure de la population, mais le facteur majeur reste l'influence de l'Examen général d'entrée, qui réglemente l'entrée dans le secondaire. Certaines écoles primaires ont un taux de réussite élevé et attirent de nombreux candidats issus de tous les secteurs de la société, tandis que les conseils et les directeurs d'écoles acceptent une surpopulation et fixent d'autres critères d'admission que ceux d'appartenance religieuse. La diversité des programmes d'études est limitée par des contraintes mises en place récemment, le gouvernement octroie l'ensemble des crédits à l'éducation et inspecte régulièrement tous les établissements scolaires. Pareils contrôles peuvent permettre au présent gouvernement d'imposer sa volonté pour diminuer l'importance de l'Examen général d'entrée, mails ils risquent en même temps de mettre en danger la tolérance religieuse engendrée aujourd'hui par la nature multiconfessionnelle des écoles religieuses.相似文献

The aim of this study was to investigate if the effects of changes in physiological arousal on timing performance can be accurately predicted by the catastrophe model. Eighteen young adults (8 males, 10 females) volunteered to participate in the study following ethical approval. After familiarisation, coincidence anticipation was measured using the Bassin Anticipation Timer under four incremental exercise conditions: Increasing exercise intensity and low cognitive anxiety, increasing exercise intensity and high cognitive anxiety, decreasing exercise intensity and low cognitive anxiety and decreasing exercise intensity and high cognitive anxiety. Incremental exercise was performed on a treadmill at intensities of 30%, 50%, 70% and 90% heart rate reserve (HRR) respectively. Ratings of cognitive anxiety were taken at each intensity using the Mental Readiness Form 3 (MRF3) followed by performance of coincidence anticipation trials at speeds of 3 and 8 mph. Results indicated significant condition × intensity interactions for absolute error (AE; p = .0001) and MRF cognitive anxiety intensity scores (p = .05). Post hoc analysis indicated that there were no statistically significant differences in AE across exercise intensities in low–cognitive anxiety conditions. In high–cognitive anxiety conditions, timing performance AE was significantly poorer and cognitive anxiety higher at 90% HRR, compared to the other exercise intensities. There was no difference in timing responses at 90% HRR during competitive trials, irrespective of whether exercise intensity was increasing or decreasing. This study suggests that anticipation timing performance is negatively affected when physiological arousal and cognitive anxiety are high. 相似文献

Abstract The purpose of this study was to determine the validity and reliability of a new method for measuring three-dimensional (3D) putting stroke kinematics using the TOMI® device. A putting robot and a high-speed camera were used to simultaneously collect data for the validity evaluation. The TOMI® device, when used in conjunction with standard 3D coordinate data processing techniques, was found to be a valid and reliable method for measuring face angle, stroke path, putter speed, and impact spot at the moment of ball contact. The validity of the TOMI® measurement system was quantified using the 95% limits of agreement method for each aforementioned variable. The practical significance of each validity score was assessed by incorporating the maximum estimated measurement error into the stroke of the putting robot for 10 consecutive putts. All putts were executed from a distance of 4 m on a straight and flat synthetic putting surface. Since all putts were holed successfully, the measurement error for each variable was deemed to be negligible for the purposes of measuring putting stroke kinematics. The influence of key kinematic errors, at impact, on the outcome of a putt was also determined. 相似文献

Objective: To develop an explicit scheme for calculating a 5‐star quality rating for consumer health information, and to test if there is good agreement be tween this and the final DISCERN quality question. Design: A sample of 15 consumers and health professionals rated 26 health information leaflets covering a broad range of conditions and treatments using two new 5‐star‐rating schemes and the existing DISCERN final quality rating. Each scheme is based on the 15 DISCERN criteria, but the 5‐star schemes provide more explicit methods for summarizing overall quality. The level of agreement between the three different rating systems was compared using Kappa scores with quadratic weights. Participants were also asked to complete a brief questionnaire that was designed to elicit their views on using a visual summary of the quality of health information. Results: The level of agreement between each 5‐star‐rating system and the existing DISCERN quality rating question was high (kappa = 0.86, 95% CI 0.83–0.89 in both instances). Seventy‐seven per cent of the sample preferred the second star‐rating scheme, and 80% reported they would use such a scheme. Conclusion: Assigning a single quality score using an explicit scoring scheme (represented by stars) based on answers to the DISCERN questionnaire is a reliable and valid way of rating consumer health information. 相似文献

Motivated by the observation that formal logic answers questions students have not yet asked, we conducted exploratory teaching experiments with undergraduate students intended to guide their reinvention of truth-functional definitions for basic logical connectives. We intend to reframe the relationship between reasoning and logic by showing how logic emerges within students’ mathematical activity. This activity entails reflecting on and systematizing their own language use across diverse semantic content. We present categories of students’ untrained strategies for assessing the truth-values for mathematical disjunctions. Students’ initial reasoning heavily reflected content-specific and pragmatic factors in ways inconsistent with the norms and conventions of mathematical logic. Despite this, all student groups reinvented the standard truth-functional definition for simple disjunctions. We demonstrate how this learning depended upon particular forms of reasoning about logic. We also contrast various strategies for assessing quantified disjunctions and their different affordances in students’ mathematical activity. 相似文献

The relative length of the second and fourth digits (2D:4D) is a putative marker for prenatal testosterone. Low 2D:4D has been reported to correlate with high performance in sport in general. Here, for the first time, we examine the relationship between 2D:4D and performance in elite rugby players. The 44 players (28 forwards, 16 backs) were drawn from the Ospreys Rugby Union Club and 44 age-matched controls. The measures of performance comprised age-adjusted number of international performances (caps) for Wales, a comparison of coaches' first-choice League team with others, and the number of tries scored by backs in club matches. Compared with controls, players were larger and had lower 2D:4D for the right and left hand. With regard to number of caps, players with low 2D:4D in their right hand and low right 2D:4D compared with their left (right?-?left 2D:4D difference) had high numbers of caps. First-choice players did not differ significantly from second-choice players in their 2D:4D but they did have a lower right?-?left 2D:4D difference than second-choice players. Low right 2D:4D and low right?-?left 2D:4D difference were significantly linked with large numbers of tries. We conclude that low right 2D:4D and low right?-?left 2D:4D difference are predictors of high rugby performance. 相似文献
