The school as a learning organisation: The concept and its measurement

A growing body of scholars, educators and policy makers has argued for reconceptualising schools as “learning organisations” in the last 25 years as. However, a lack of clarity on the concept has hindered its advance in theory and practice. This study responds to this problem by developing a schools as learning organisations scale that expands and clarifies the concept on several points. Drawing on survey data (nschool staff = 1,703) from Wales (UK), it examines the key characteristics of a school as a learning organisation through a principal component analysis and reliability analysis. The results showed that such a school is associated with eight dimensions: (a) a shared vision centred on the learning of all students, (b) partners contributing to school vision, (c) continuous learning opportunities, (d) team learning and collaboration, (e) a culture of enquiry, innovation and exploration, (f) systems for collecting and exchanging knowledge and learning, (g) learning with and from the external environment, and (h) modelling learning leadership. The resulting 65-item scale demonstrated good psychometric qualities. A reliable and valid schools as learning organisations scale can help enhance our understanding of the concept. The scale can also be used by school leaders, teachers and all others wanting to develop a thriving learning culture in their schools.  相似文献   

Effect of high glucose levels on the calcification of vascular smooth muscle cells by inducing osteoblastic differentiation and intracellular calcium deposition via BMP-2/Cbfα-1 pathway     

Liu F  Zhong H  Liang JY  Fu P  Luo ZJ  Zhou L  Gou R  Huang J 《Journal of Zhejiang University. Science. B》2010,11(12):905-911

In this paper,we investigate the effect and the possible mechanism of high glucose levels on the calcification of human aortic smooth muscle cells (HASMCs).HASMCs were divided into four groups: normal glucose group (NG),osmolality control group (OC),high glucose group (HG,HASMCs culture medium containing 30 mmol/L glucose),and high glucose plus recombinant human Noggin protein (bone morphogenetic protein-2 (BMP-2) antagonist) group (HN).The mRNA levels and the protein expressions of BMP-2 and core binding factor alpha-1 (Cbfα-1) were measured by real-time quantitative polymerase chain reaction (PCR) and Western blot.After induced by 10 mmol/L β-glycerol phosphoric acid,cells were harvested for assessments of alkaline phosphatase (ALP) activities at Days 1,2,and 3,and intracellular calcium contents at Days 7 and 14,respectively.High glucose levels increased the mRNA levels and the protein expressions of BMP-2 and Cbfα-1 (P0.05).The expression of Cbfα-1 was partially blocked by Noggin protein (P0.05),while BMP-2 was not (P0.05).After being induced by β-glycerol phosphoric acid,high glucose levels increased the ALP activity [(48.63±1.03) vs.(41.42±2.28) U/mg protein,Day 3;P0.05] and the intracellular calcium content [(2.76±0.09) vs.(1.75±0.07) μmol/mg protein,Day 14;P0.05] in a time-dependent manner when compared with the NG group,while the ALP activity could not be blocked by Noggin protein [(48.63±1.03) vs.(47.37±0.97) U/mg protein,Day 3;P0.05].These results show that high glucose levels can evoke the calcification of HASMCs by inducing osteoblastic trans-differentiation and intracellular calcium deposition via the BMP-2/Cbfα-1 pathway,which can be partially blocked by Noggin protein.  相似文献

Correlates of sexual abuse and smoking among French adults     

King G  Guilbert P  Ward DG  Arwidson P  Noubary F 《Child abuse & neglect》2006,30(6):709-723

OBJECTIVE: The goal of this study was to examine the association between sexual abuse (SA) and initiation, cessation, and current cigarette smoking among a large representative adult population in France. METHOD: A random sample size of 12,256 adults (18-75 years of age) was interviewed by telephone concerning demographic variables, health practices and beliefs, and health status--for which SA and tobacco questions were included. Bivariate and multivariate analyses were conducted. RESULTS: Nearly 46% of SA survivors were current smokers compared to 34% of non-abused persons (p<.001). Survivors of SA consumed more cigarettes per day than non-abused individuals (14.5 vs. 12.4, p<.01). Survival analysis showed an increased risk of smoking initiation for respondents abused before 18 (adjusted relative hazard=1.55; p<.0001) with referent to the non-abused group. SA was not found to be a significant predictor of current smoking status among those who began smoking after the first incident of SA. Respondents who were not sexually abused were 1.8 times (95% CI, 1.12-2.99) more likely to quit smoking than people who began smoking after they were sexually abused. CONCLUSIONS: The early identification and treatment of sexually abused persons is critical to decrease smoking among adolescents and adults because of the association of SA with both smoking initiation and decreased cessation rates. It may be more difficult to detect an association between SA and current smoking due to the high rates of smoking and lower rates of quitting among the general French population.  相似文献   

A EUROPEAN INSTITUTIONAL AUDIT     

Pierre Tabatoni 《Higher Education in Europe》1995,20(1-2):108-115

The project of CRE for a European institutional audit of higher education institutions is presented, justified, and briefly described. It responds to the increasing concerns of all actors involved in higher education with quality in every meaning of the word. As the integration of Europe proceeds, as course programmes increasingly emphasize inter‐disciplinarity, as students and teachers become increasingly mobile, the role and importance of such a Europe‐wide audit is enhanced.

Intrafamilial sexual abuse: brother-sister incest does not differ from father-daughter and stepfather-stepdaughter incest     

Cyr M  Wright J  McDuff P  Perron A 《Child abuse & neglect》2002,26(9):957-973

OBJECTIVE: Three groups of girls who were sexually abused (by either brothers, fathers, or stepfathers) were compared. The purpose was to identify the differing characteristics of the abuse, the family environments, and the psychosocial distress of these children. METHOD: Seventy-two girls aged between 5 and 16 were assigned to one of the three groups. Subjects were matched between groups on the basis of their actual age. Children completed measures of traumatic stress; their mothers completed the Child Behavior Checklist-Parent Report Form (CBCL) and other self-report questionnaires on family characteristics. Workers in child protective services completed information regarding the nature and severity of the abuse. RESULTS: Results suggested few differences in the characteristics of sexual abuse between the three groups. However, penetration was much more frequent in the sibling incest group (70.8%) than in the stepfather incest (27.3%) or father incest (34.8%) groups. Ninety percent of the victims of fathers and brothers manifested clinically-significant distress on at least one measure, whereas 63.6% of stepfather victims did. Compared with father and stepfather perpetrators, brothers were raised in families with more children and more alcohol abuse. CONCLUSIONS: The authors conclude that the characteristics of brother-sister incest and its associated psychosocial distress did not differ from the characteristics of father-daughter incest These findings suggest that theoretical models and clinical practices should be adjusted accordingly and that sibling incest should not necessarily be construed as less severe or harmful than father-daughter incest.  相似文献

从某种意义上讲,知识产权保护正在成为发达国家打压发展中国家技术创新的有力武器,如果不加限制,必将成为知识“霸权”。中国的科技发展正处在转型的关键时期,迫切需求对知识“霸权”进行规制,使之更好地为中国技术创新服务。  相似文献

Impact of Contact With Grandparents on Children's and Adolescents’ Views on the Elderly     

Allison Flamion  Pierre Missotten  Manon Marquet  Stéphane Adam 《Child development》2019,90(4):1155-1169

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts).  相似文献
