特权用户阻碍IT建设

谈到商业智能(BI),专栏作家Rick Sherman说,商业用户和IT企业之间就此问题存在着种种矛盾。但人们并不用对此过于担心,因为商业智能取得成功的关键在于那些特权用户。你是否想过,为什么很多公司从商业智能销售商那里购买了具有成百上千功能的软件,却仅使用其中的少许功能?为什么企业的员工在他们的IT解决方案中已经选定了一个商业智能工具,并打算不使用微软公司的Ex- cel时候,仍然还使用Excel作为他们的     

Volunteer youth sport coaches' perspectives of coaching education/certification and parental codes of conduct

The vast majority of youth sport programs in the United States relies primarily on parent volunteers to serve as coaches. Unfortunately, most of these volunteer coaches have not received formal training to prepare them adequately for the role of youth sport coach. To exacerbate the issue, according to the popular media, parents and other adults can commit belligerent and even violent acts around, and often resulting from, poorly managed youth sport events. Although some efforts have been made to standardize curricula, provide training for coaches, and contain or prevent inappropriate parent behaviors, few efforts have been directed at investigating the self-described needs and concerns of the coaches from their perspectives. The purpose of the current study was to investigate the concerns and issues of youth sport coaches related to coaching and parental education. Five focus group interviews with 25 volunteer youth sport coaches were conducted to investigate these issues. Results were organized around four higher order themes that emerged from inductive content analyses: (a) coaching education content areas of need, (b) barriers and problems of offering coaching education, (c) coaching education format recommendations, and (d) efficacy of parental codes of conduct. Results were discussed in terms of the potential impact administrators, coaches, and parents could have in implementing formal coaching education programs and developing their coaching education practices.

Speech patterning of natural discourse of well and depressed mothers and their young children

The speech behavior of 14 depressed and 18 nondepressed mothers during conversations with their 3-year-old children was examined in this study. Given the general motor retardation, reduced energy level, and social withdrawal of depressed individuals, the speech patterns of depressed mothers were predicted to differ from the speech patterns of well mothers. Depressed mothers vocalized less often and responded less quickly to the cessation of their children's speech than healthy mothers. However, in a mildly stressful situation (awaiting a doctor's visit) the depressed mothers, but not the healthy mothers, significantly increased their level of speech productivity. Children of the depressed mothers spoke less than children of healthy women, particularly while sitting and eating lunch with their mothers. The observed difference in the mothers' behaviors was interpreted as an indication that the 2 groups of children are exposed to very different patterns of socialization. The offspring of depressed women are being taught both to keep social interaction to a minimum and to be overreactive to even mild stresses. The differences in the children's behavior may indicate that already these 3-year-old children have learned to keep their interactions with their mother to a minimum. This manner of adaptation may have negative effects on the child's continued social, emotional, and cognitive development.     

Pre-service Teachers’ Experiences with a Science Education Module

This paper describes a module provided to first year elementary participants in a two-year after-degree Bachelor of Education program. The module was specifically designed to address the fact that pre-service teachers can enter the B.Ed. degree with little or no science knowledge. Science experiences were explicitly incorporated into the B.Ed. module described here linking science content knowledge to specific science pedagogic content knowledge. The pre-service teachers were surveyed and interviewed during and after completion of the module. It was found that the inquiry based approach increased the pre-service teachers' level of science knowledge, their confidence with regard to teaching elementary science, and improved their attitude toward science teaching and learning.     

Regional disparities in primary school participation in developing countries

Education for All has focused international attention on the goals of universal primary education and improved education quality. However, national indicators related to these goals often mask significant differences among demographic and social groups, as well as among geographical regions within countries. This paper, based on a study commissioned by UNESCO’s Global Monitoring Report team, examines within-country (regional) disparities in participation in primary education in between 55 and 60 countries in sub-Saharan Africa, Asia and the Pacific, Latin America and the Arab States. After reviewing the methodology used in the analysis, the paper compares countries’ disparities in net enrolment rates before and after the Dakar Framework was established in 2000, changes over the pre- to post-Dakar period and a comparison of net enrolment rates with pupil-teacher ratios—one of the standard measures of education quality. Overall, the analysis finds significant differences in the magnitude of regional disparities in primary participation across the countries, with the smallest disparities in Latin America and the largest in sub-Saharan Africa. While just over half the countries with both pre- and post-Dakar data showed improvements over the period, there was little change in countries’ rankings on the disparities measures over this period.     

Effects of Leader and Teacher Behaviour on Implementation of Cooperative Learning in the Elementary School

Structural equation modelling was used in this study to examine interrelationships among change management functions, teacher orientations and implementation of cooperative learning which were assessed in terms of four latent variables based on teacher self‐reports of knowledge, perceived benefits, amount of professional development and frequency of use. After preliminary modifications, the final structural model suggested four major influences on implementation. First, lower levels of pupil control ideology of the teacher lead to more self‐reported knowledge of cooperative learning methods. Pupil control ideology is a measure of how school personnel view their students with regard to control. The higher the pupil control ideology, the more controlled the classroom. Second, higher levels of shared vision and lower levels of pupil control ideology lead to stronger teacher perceptions of the benefits of using cooperative learning. Third, higher levels of principal and resource support —but lower levels of teacher participation in decision making—lead to more professional development experiences.     

Education in early postcolonial India: expansion,experimentation and planned self-help

After independence India’s leaders committed the country to democracy with universal franchise and to pursuing a socialistic pattern of society. As part of these interlocking projects, it was widely recognised that India’s educational systems needed reform. However, with scarce resources, Indian policy-makers faced the dilemma of whether to improve the existing system, which served a narrow, urban elite, or expand it to the entire population, as the Constitution promised they would. This overview of education policy in the first two decades after 1947 finds that, at the centre, Indian planning did not monopolise control over education. Rather, India’s was a socialism of scarcity, which relied on self-help efforts by the people to build the institutions of the welfare state. However, by relying on communities to use their own resources to build local schools, this DIY socialism entrenched existing inequalities.
