The purpose of the present study was to develop a questionnaire to assess student attitudes towards school by describing the
factors that affect these attitudes. For this purpose, a sample of 362 (11–13 years-old) elementary-school students was used.
Both exploratory and confirmatory factor analyses were carried out. The questionnaire consists of six factors (Belongingness
to School, School Image, Loneliness at School, Teaching, Testing and Feedback-Giving Activities, and Reluctance). When data
were tested via structural equation modelling, examination of fit indices indicated that the model came close to fitting the
data with goodness-of-fit coefficients at recommended levels. The School Attitude Questionnaire was found to be suitable in
the light of the findings of our study, and its scales are thought to affect students’ attitudes towards school. 相似文献

British rule over Palestine between 1920 and 1948 was a vibrant and fateful period in the modern history of the country in all arenas (political, economic, societal, demographic and cultural), one of the most active of which in Palestinian society at the time was education. Many Palestinian educators assumed their role as freedom fighters, agents of Arab nationalism and defenders of the homeland. These educators saw the British and the Zionists as bitter enemies to be resisted and expelled, though some had a distinctly progressive humanistic vision that allowed them to view the collective enemy as worthy human beings. This complex reality created many internal contradictions and difficulties among these humanistic educators, led by prominent Palestinian educator Khalil al-Sakakini (1878–1953). This article attempts to describe and understand Sakakini’s contradictions and internal conflicts and how he dealt with these internal contradictions and distinguished between Jews and Zionists. 相似文献

ABSTRACTAs developed countries struggle to find suitable living arrangements for their ageing populations, many elderly citizens are becoming increasingly marginalized and isolated. In similar circumstances, younger people would use digital technologies to stay occupied and connected, but few elderly citizens have this capability. Our research investigates the ways that the social wellbeing of elderly citizens, wherever they reside, can be enhanced by their use of information and communications technologies (ICT), particularly digital technologies. A 2-year action research study of the social use of ICT by residents in aged-care facilities was conducted in order to determine how developing digital capabilities could enhance their wellbeing. Research interventions included the establishment of computer kiosks in aged-care facilities and weekly classes for developing ICT skills. As their digital capability improved, many of the elderly residents were observed to engage in meaningful computer-based activities of their own choosing. A set of themes among these activities was identified: connection, self-worth/esteem and personal development, productivity, occupation, self-sufficiency, being in control, and enjoyment. Our results are consistent with recently reported domains of social wellbeing among recipients of community-based aged-care services: (a) social participation and involvement, (b) occupation, (c) control over daily life and (d) dignity. 相似文献

兰巴尼派是17世纪产生于印度的苏非主义教派,即革新的纳合西班底耶。该派在新疆早期依禅派(苏非派、白山派和黑山派衰落之机传入新疆南部。大量黑山派和白山派信徒放弃原来的信仰,成为正统逊尼派或者兰巴尼派的信徒。和卓时期新疆最大的依禅派——黑山派和白山派,演变成兰巴尼派,正统逊尼派重新成为维吾尔族伊斯兰教的主流,依禅派则迅速退居次要地位,但对新疆近现代维吾尔族依祥派而言,兰巴尼派已成为依禅派的主要流派。文章以笔者的调研为主,结合有关史料和前人研究成果,较系统地分析了近现代维吾尔族依禅派的来源和特点.为进一步探讨当代维吾尔族依禅派的现状和发展提供了历史线索。 相似文献

Based on interviews with 24 faculty members at a large, public university, this article reports the use of metaphors as a new conceptual strategy to analyze change in higher education organizations. Results of the study indicate that strategic choices guiding the behavior of the organization under study and the metaphorical images held by the faculty members about their organization show a high degree of congruence. Implications for change and maintenance of enacted realities in higher education organizations are discussed. 相似文献

Active crystal facets can generate special properties for various applications. Herein, we report a (001) faceted nanosheet-constructed hierarchically porous TiO2/rGO hybrid architecture with unprecedented and highly stable lithium storage performance. Density functional theory calculations show that the (001) faceted TiO2 nanosheets enable enhanced reaction kinetics by reinforcing their contact with the electrolyte and shortening the path length of Li+ diffusion and insertion-extraction. The reduced graphene oxide (rGO) nanosheets in this TiO2/rGO hybrid largely improve charge transport, while the porous hierarchy at different length scales favors continuous electrolyte permeation and accommodates volume change. This hierarchically porous TiO2/rGO hybrid anode material demonstrates an excellent reversible capacity of 250 mAh g–1 at 1 C (1 C = 335 mA g–1) at a voltage window of 1.0–3.0 V. Even after 1000 cycles at 5 C and 500 cycles at 10 C, the anode retains exceptional and stable capacities of 176 and 160 mAh g–1, respectively. Moreover, the formed Li2Ti2O4 nanodots facilitate reversed Li+ insertion-extraction during the cycling process. The above results indicate the best performance of TiO2-based materials as anodes for lithium-ion batteries reported in the literature. 相似文献

This study reports the utilization of serum fructosamine and blood glucose for the screening of gestational diabetes mellitus
(GDM). Blood samples from 165 pregnant women were analyzed for fasting blood glucose (FBG), random blood glucose (RBG) and
serum fructosamine. The actual fructosamine levels were corrected for serum protein (c-Fruct) for more precise presentation.
Two cut-off values of FBG (>5.3 mmol/L and >7.0 mmol/L) and RBG (>7.8 mmol/L and >11.0 mmol/L) were used to classify hyperglycemic
subjects for subsequent evaluation. The average values±standard deviations for FBG, RBG and cFruct were 5.865±1.95, 7.767±3.21
and 2.387±0.47 mmol/L, respectively. FBG levels were significantly correlated with RBG (Pearson correlation=0.597, P<0.001).
Significant correlations were also observed between cFruct and FBG (Pearson correlation=0.673, P<0.001) or RBG (Pearson correlation=0.641,
P<0.001). Out of 165 subjects, 24 (14.5%) cases were classified as hyperglycemic on the basis of FBG>7.0 mmol/L or RBG>11.0
mmol/L; use of lower cut-off values resulted higher frequencies of hyperglycemia. Whereas, a combined criteria of FBG>5.3
mmol/L and cFruct >2.5 mmol/L predicted 35 patients as the most probable hyperglycemic as compared to 32 patients identified
using the criteria of RBG >7.8 mmol/L and cFruct >2.5 mmol/L. These criteria were associated with 4.8% and 3.6% false-positivity
at the expense of 3.6% and 3.0% false-negative outcomes, respectively. The levels of FBG, RBG and cFruct were significantly
higher in hyperglycemic groups (irrespective of grouping criteria) as compared to the respective normal groups. In conclusion,
these findings clearly indicate that the paired values of cFruct with FBG or RBG could help in filtering high-risk individuals
for OGTT and therefore avoiding a unnecessary OGTT. 相似文献

Hemodynamically significant ductus arteriosus (hsPDA) may alter organ perfusion by interfering blood flow to the tissues. Therefore, in infants with hsPDA, hypoxia occurs in many tissues. In this study, we aimed to investigate the diagnostic significance of serum (ischemia-modified albumin) IMA levels as a screening tool for hsPDA, and its relation to the severity of the disease in the preterm neonates. For this purpose, seventy-two premature infants with gestation age <34 weeks were included in the study. Thirty premature infants with hsPDA were assigned as the study group and 42 premature infants without PDA were determined as the control group. Blood samples were collected before the treatment and 24 h after the treatment, and analyzed for IMA levels. IMA levels in the study group (1.26 ± 0.36 ABSU) were found to be significantly higher than control group (0.65 ± 0.12 ABSU) (p < 0.05). In infants with hsPDA, a positive correlation was found between IMA and PDA diameter (ρ = 0.876, p = 0.022), and LA/Ao ratio (ρ = 0.863, p = 0.014). The cut-off value of IMA for hsPDA was measured as 0.78 ABSU with 88.89 % sensitivity, and 90.24 % specificity, 85.71 % positive predictive, 92.5 % negative predictive value [area under the curve (AUC) = 0.96; p < 0.001]. The mean IMA value of the infants with hsPDA before treatment was 1.26 ± 0.36 ABSU, and the mean IMA value of infants after medical treatment was 0.67 ± 0.27 ABSU (p = 0.03). We concluded that IMA can be used as a marker for the diagnosis and monitoring of a successful treatment of hsPDA. 相似文献
