道德规范与图书馆事业

美国图书馆协会的《职业道德规范声明》提出了以图书馆事业为中心的具体原则,其《图书馆权利法案》则明确了图书馆的责任和义务。目前,美国社会和政治环境的变化为图书馆职业带来了越来越多的忧虑和压力。"9·11"后出台的《爱国者法案》明显与图书馆职业道德规范中所阐述的重要原则相冲突。因此,美国图书馆协会决心抵制《爱国者法案》对知识、信息自由开放以及行使个人隐私权的限制。     

Balancing tensions in educational policy reforms: large-scale implementation of Assessment for Learning in Norway

This study investigates how different stakeholders in Norway experienced a government-initiated, large-scale policy implementation programme on Assessment for Learning (AfL). Data were collected through 58 interviews with stakeholders in charge of the policy; Ministers of Education and members of the Directorate of Education and Training in Norway, and the main actors such as municipality leaders, teachers, school leaders and students. Successful implementation of AfL processes was found in municipalities where there were dialogue and trust between the municipality level, school leaders, teachers and students and where the programme was adapted to the local context. Implementation was challenged when the policy was interpreted as a way of controlling the schools. Despite the successful implementation in some municipalities, the programme did not have any effect upon students’ learning outcome, as measured on national tests in reading and mathematics. The results are discussed in relation to how local assessment cultures with particular characteristics influence governing, accountability and trust.     

Dominant–non-dominant asymmetry of kicking a stationary and rolling ball in a futsal context

The aim of this study was to analyse the characteristics of the asymmetries in the dominant and non-dominant limbs when kicking stationary and rolling balls. Ten experienced Brazilian amateur futsal players participated in this study. Each participant performed kicks under two conditions (stationary ball vs. rolling ball) with the dominant and non-dominant limbs (five kicks per condition per limb). We analysed the kicking accuracy, ball and foot velocities, angular joint displacement and velocity. The asymmetry between the dominant and non-dominant limbs was analysed by symmetry index and two-way repeated measures ANOVA. The results did not reveal any interaction between the condition and limb for ball velocity, foot velocity and accuracy. However, kicking with the dominant limb in both kicks showed higher ball velocity (stationary ball: dominant – 24.27 ± 2.21 m · s^?1 and non-dominant – 21.62 ± 2.26 m · s^?1; rolling ball: dominant – 23.88 ± 2.71 m · s^?1 and non-dominant – 21.42 ± 2.25 m · s^?1), foot velocity (stationary ball: dominant – 17.61 ± 1.87 m · s^?1 and non-dominant – 15.58 ± 2.69 m · s^?1; rolling ball: dominant – 17.25 ± 2.26 m · s^?1 and non-dominant – 14.77 ± 2.35 m · s^?1) and accuracy (stationary ball: dominant – 1.17 ± 0.84 m and non-dominant – 1.56 ± 1.30 m; rolling ball: dominant – 1.31 ± 0.91 m and non-dominant – 1.97 ± 1.44 m). In addition, the angular joint adjustments were dependent on the limb in both kicks (the kicks with non-dominant limb showed lower hip external rotation than the kicks with the dominant limb), indicating that the hip joint is important in kick performance. In conclusion, the kicks with the non-dominant limb showed different angular adjustments in comparison to kicks with the dominant limb. In addition, kicking a rolling ball with the non-dominant limb showed higher asymmetry for accuracy, indicating that complex kicks are more asymmetric.     

Ochronosis of the Hip Joint: Differential Diagnosis of Inflammatory Arthropathy with Lytic Lesion

Alkaptonuria or ochronosis is a rare inborn disorder of metabolism which is characterized by deficiency of homogentisic acid oxidase. There is accumulation of homogentisic acid in the connective tissues causing brownish black pigmentation and skeletal damage. The most serious complication of this disease is crippling degenerative arthropathy which presents in late years of life. There is no definitive treatment for the condition. Symptomatic management is the main stay. Surgical management such as arthroplasty is done for severe cases of ochronosis. We report a case of ochronosis of the hip joint presenting with inflammation and lytic lesion which can create confusion and lead to error in diagnosis.
