《DANGEROUS》

当这支歌曲的旋律在耳边响起时，我总会不自觉地打起响指和着节拍摇摆身体，想要舞蹈。我喜欢这首歌和这支舞蹈营造的气氛，神秘得充满躁动，引着我们投入音乐之中，让我们正视自己内心的渴望。     

The effects of frequency of encouragement on performance during maximal exercise testing

The aim of this study was to determine the effects of frequency of verbal encouragement during maximal exercise testing. Twenty-eight participants (12 males, 16 females) aged 20.9 +/- 1.5 years (mean +/- s) performed a maximal exercise test (VO2max) on a treadmill without any verbal encouragement. The participants were matched according to their pre-test VO2max and placed into either a control group or one of three experimental groups. They performed a second exercise test (post-test) 1 week later. During the second test, the control group received no verbal encouragement; the 20 s (20E), 60 s (60E) and 180 s (180E) encouragement groups received verbal encouragement every 20, 60 and 180 s, respectively, beginning with stage 3 of the exercise test. Relative VO2max, exercise time, blood lactate concentration, respiratory exchange ratio (RER) and ratings of perceived exertion (RPE) were not significantly different from the first test to the second test for the control group without verbal encouragement and the 180E group that received infrequent encouragement. Post-test values were significantly higher than pre-test values for the 20E and 60E groups. The post-test values of the 20E group were significantly higher than their pre-test values for relative VO2max (P < 0.001), exercise time (P < 0.0001), blood lactate concentration (P < 0.05), RER (P < 0.01) and RPE (P < 0.0001); this was also the case for the 60E group for relative VO2max (P < 0.01), blood lactate concentration (P < 0.05), RER (P < 0.05) and RPE (P < 0.05). The results suggest that frequent verbal encouragement (every 20 s and 60 s in the present study) leads to significantly greater maximum effort in a treadmill test than when no encouragement is given or when the encouragement is infrequent (i.e. every 180 s).     

How should we categorise self-reported data on subsequent injuries?*

Classifying subsequent injuries is of high importance in injury epidemiology since a previous injury has been reported to increase the risk of a new injury or increase the risk of a more severe injury. Multiple reports have shown that self-reported data provide an extensive view of an injury problem and add valuable information to the understanding of the athlete’s health. The purpose of this study was to display a method that can be used to facilitate classification of subsequent injuries and to discuss challenges faced when categorising subsequent injuries based on self-reported data. The suitability of a new model for Subsequent Injuries Adjusted for Self-reported data (SIAS model) was demonstrated with sport injury data from a cohort of 101 adolescent elite track & field athletes, followed over 52 weeks. A total number of 71 subsequent injuries were identified. Of all subsequent injuries, recurrent injuries represented 69.0% (n?=?49) and 31.0% (n?=?22) were classified as new injuries. The majority of subsequent injuries (n?=?60, 84.5%) occurred after athletes had recovered from a previous injury. Of all subsequent injuries, 15.5% (n?=?11) represented injuries where athletes had not fully recovered from a previous injury. Application of the SIAS model allows for classification of subsequent injuries based on self-reported data on the recovery level of the athletes, the injury onset and injury type. The developed SIAS model follows the consensus recommendations of injury definition, injury classification and is an attempt to increase the understanding of the complex relationship of subsequent injuries in self-reported data sets.     

Recent educational research on developing countries by German researchers: A survey of the literature

How have recent trends in German educational research applied to developing countries? In order to outline the immediate state of this research in the FRG (1980–1983), the contribution first gives a brief review of its process from the beginning. The first part examines educational research until 1980, and then differentiates three main types of research on educational problems in Third World countries (on the implementation of projects; on the evaluation of education programmes and measures of educational aid; on education systems and the correlation between education and development). Through a survey of the literature published since 1980, the article aims to give an idea of the contemporary topics of this research and furthermore tries to show how German educationists try to come to terms with the failures of educational aid projects, also how they try to construct new and adequate theoretical models.     

Student Teachers’ Beliefs and a Changing Teacher Role

This article discusses the encounters between the changing expectations on the teacher role, teacher education and Swedish student teachers’ beliefs about their role as teachers, with special emphasis on the socialisation process of the pupils and the teacher's possible influence on it. The discussion is based on two empirical studies among Swedish compulsory school student teachers (M. von Wright, (1996) Propedeusis? Om motet mellan lärarstuderande och lärarutbildningen, in: Grundskollärarutbüdningen 1995. En utvärdering. Högskoleverkets rapportserie 1996:1 R.; M. von Wright (1997) Socialisationsprocessen. Metaforer och synsätt hos blivande lärare. Licentiatuppsats. Lärarhögskolan i Stockholm). The results show that student teachers when they enter their education on the one hand tend to carry with them explicit expectations which strongly reflect the values of what is considered pedagogically correct. At the same time students express implicit beliefs and underlying conceptions of human development, which in many cases are incoherent. During teacher education the pedagogically correct beliefs might become replaced, but implicit beliefs as affinity to certain pedagogical discourses are not changed or brought to awareness unless they are seriously challenged and problematised. Yet these beliefs direct the students’ attention. Changing demands on the teacher role bring about expectations on a shift in thinking about teaching and learning. Teacher education and educators can play important roles in making the students aware of their everyday beliefs and eventually change them.     

So near and yet so far: a grounded theory study of incarcerated Filipino elderly’s experiences of emotional geography

ABSTRACT

Emotional geography defines how emotions affect the interaction of individuals within their setting. Considering that prison has been described as a place saturated with negative emotions, previous studies have only dwelt on the negative impact of incarceration on the emotional well-being and interactions of the inmates. However, no attempt has been made that dilates on how emotional geography facilitates the establishment of good relationships inside the penal institution, hence this investigation. The overall intent of this investigation is to describe the process of emotional geography among a select group of incarcerated Filipino elderly. This study utilized the qualitative, grounded theory design. A purposive sample of 25 incarcerated Filipino elderly from the New Bilibid Prison in Muntinlupa City, Philippines participated in this study. Interestingly, this study afforded the development of de Guzman, Henson, Gumba, Fradejas, and Valdez Shoelace Model of Emotional Geography which describes how the incarcerated Filipino elderly’s emotions affect their interactions in achieving positive relationships with other inmates while inside the penal institution. This emerged model is comprised of three phases, namely: isolating (embracing a wall of mistrust), integrating (making connections through shared stories), and intertwining (strengthening the bonds thru emotional understanding). The emerged theoretical model has successfully described the process of emotional geography, which can be utilized by gerontological workers, nurses and other health professionals in addressing and accommodating the social and custodial needs of this vulnerable group.     

Collaborative Approaches to Resolving Difficult ILL Borrowing Requests: Using a Working Group and a Wiki for Knowledge Sharing

Interlibrary loan borrowing staff at the University of Arizona Main Library, who handle difficult interlibrary loan requests, are taking a collaborative approach to obtaining unique, difficult-to-locate materials. A working group within the document delivery team meets weekly to share examples processed during the preceding week to increase the fill rate of challenging interlibrary loan requests. The group also established a wiki for the purpose of sharing resources that have been used to solve difficult requests. The wiki serves as an advanced interlibrary loan training resource that can be accessed by a greater number of staff, enabling them to gain the skills necessary to process difficult requests.     

Construir la realidad

RESUMEN

El autor parte del postulado de que el entorno, tal como lo percibimos, es invención nuestra y propone una serie de experimentos para demostrarlo. Plantea que el conocimiento es una computación de la realidad y que los procesos cognitivos son procesos de computación recurrente. Con el fin de entender esta computación a nivel neural se describe la estructura de las neuronas y el proceso de la transmisión sináptica, poniéndose como ejemplo la percepción visual. El sistema nervioso tiene además una unidad funcional y sus computaciones están sujetas a una constricción no-trivial, organizándose de tal modo que computa una realidad estable. Este nuevo postulado estipula la autonomía y la autorregulación de todo ser viviente.
