Classification and Subject Indexing Issues at a Mexican Library Specializing in Law Research

Abstract

Subject indexing and classification of law resources is a complex issue due to several factors: specialized meanings of legal terms, meanings across different branches of law, terms in legal systems from diverse countries, and terms in different languages. These issues led to the development of a classification and subject indexing system which will help answer the major challenges of indexing and classifying law resources in the Research Institute Library at the National Autonomous University of Mexico. Adopting its own classification required interdisciplinary work between law and information organization specialists, constant updating by legal specialists and others beyond the Legal Research Institute; and the sharing of this classification system with other institutions. Now, this classification system is used by important institutions that specialize in law, such as the network of Libraries of the Supreme Court of Justice of the Nation of Mexico. The purpose of this article is to show why and how this law classification and subject system was developed and is continuously being updated by libarians and law scholars in order for it to meet their specific needs.     

Tune discrimination in monkeys (Cebus apella) and in rats

Monkeys and rats were trained on an operant discrimination employing structured auditory stimuli (tunes). The rats acquired the tune discrimination very rapidly and considerably faster than the monkeys. Both species generalized the discrimination across intensity and octave transformations. Discriminative performance remained at a high level when only the first halves of the tunes were presented, but substantially less generalization occurred to the second halves. Rats trained with tones (broken or steady) required three to four times more training to reach criterion than did the rats trained with tunes. The potential of structured auditory stimuli for investigations of information-processing mechanisms in animals is pointed out.     

Caffeine ingestion enhances perceptual responses during intermittent exercise in female team-game players

We examined the influence of caffeine supplementation on cognitive performance and perceptual responses in female team-game players taking low-dose monophasic oral contraceptives of the same hormonal composition. Ten females (24 ± 4 years; 59.7 ± 3.5 kg body mass; 2–6 training sessions per week) took part in a randomised, double-blind, placebo-controlled crossover-design trial. A 90-min intermittent treadmill-running protocol was completed 60 min following ingestion of a capsule containing either 6 mg ? kg^?1 anhydrous caffeine or artificial sweetener (placebo). Perceptual responses (ratings of perceived exertion (RPE), feeling scale (FS), felt arousal scale (FAS)), mood (profile of mood states (POMS)) and cognitive performance (Stroop test, choice reaction time (CRT)) were completed before, during and after the exercise protocol, as well as after ~12 h post exercise. Caffeine ingestion significantly enhanced the ratings of pleasure (P = 0.008) and arousal (P = 0.002) during the exercise protocol, as well as increased vigour (POMS; P = 0.007), while there was a tendency for reduced fatigue (POMS; P = 0.068). Caffeine ingestion showed a tendency to decrease RPE (P = 0.068) and improve reaction times in the Stroop (P = 0.072) and CRT (P = 0.087) tests. Caffeine supplementation showed a positive effect on perceptual parameters by increasing vigour and a tendency to decrease fatigue during intermittent running activity in female games players taking low-dose monophasic oral contraceptive steroids (OCS).     

Developing the characteristic spirit of publicly managed schools in a more secular and pluralist Ireland

This discussion paper considers the identification and definition of the ‘characteristic spirit’ of publicly managed schools in the Republic of Ireland. Some international approaches to values in publicly funded schools are introduced along with relevant contextual aspects of Irish education including the cultural diversity and secularisation of modern Irish society. The Irish Education Act (1998) gives ultimate responsibility for school values and ‘characteristic spirit’ to the school ‘patron’, a role legally separate from that of school ownership and school management. The underlying values of privately managed faith-based schools are well established. However, the ‘characteristic spirit’ of publicly managed Education and Training Board schools remains largely undeveloped. Appropriate responses to this challenge are identified and discussed.     

Children’s voices in mini soccer: an exploration of critical incidents

Since being adopted by The English Football Association as the preferred format of football to be played by children aged 10 and under, mini soccer has evolved and expanded into a popular activity for children. Yet little is known about the experiences of those participating in the game. In addition, adult-organized activities such as mini soccer are increasingly seen by parents and adults as suitable pursuits for their children to participate in. Yet the perspective of the child participating in mini soccer, as with many other activities, is largely ignored in academic literature. This is especially true in the social sciences, where research has historically been done ‘on’ children, rather than ‘with’ children. In this study, we seek to address this imbalance by including children as active participants in the research process. In doing so, we devised a methodology based on audiovisual methods to create participatory conditions between children and researchers interested in investigating their experiences of mini soccer in England. Children were asked to identify aspects of their experience which they felt were noteworthy to create video recordings of critical incidents that directly involved them participating in mini soccer. These were used as a discussion tool in focus groups to explore how and why children felt the incidents were critical, and how their experience of them shaped their participation. The methodology employed helped capture children’s differentiated views of the same incidents, and highlighted the diversity of their experiences. It is recommended that similar audiovisual methodologies are employed to inform future policy and strategy development in grassroots football that includes children as participants.     

Impact attenuation of protective boxing and taekwondo headgear

This study aimed to compare the impact attenuation performance of boxing and taekwondo headgear in terms of peak linear and rotational acceleration. To measure the impact attenuation of headgear, a standardized (American Society for Testing and Materials (ASTM) F-2397) martial arts headgear striker was used to impart impacts to a 50th Percentile Male Hybrid III Crash Test Dummy head and neck complex. Two boxing (Adidas and Greenhill) and two taekwondo (Adidas and Nike) headgear, approved by the Association Internationale de Boxe Amateur and the World Taekwondo Federation (WTF), were selected. Each of the selected headgear was fitted to the Hybrid III head and subsequently subjected to five impacts at the front and side with a maximum impact interim time of 60 seconds by the rotating striker at 8?±?0.3?m/s. Linear and rotational acceleration were recorded at 10,000?Hz. There were significant interactions of the impact location and brand on the rotational acceleration, F(3,40)?=?6.7, p?F(1,40)?=?9.07, p?F(3,40)?=?9.9, p?相似文献
