The role of philosophy of education has become seriously blurred with constant cries for practical and immediate answers. The nature of the discipline is such that when practical solutions are demanded of it, it loses its vitality. Philosophy is an intellectual and contemplative exercise; it is a true activity of leisure, one which needs to be enjoyed for its own sake. This intellectual and contemplative activity is of service to the practical concerns of education because choice, action, and judgment — the concerns of the practical realm —depend upon intellectual knowledge. Philosophy of education is, therefore, an essential discipline in the education of the student-teacher. 相似文献

Hispanics face multiple barriers to academic achievement. This study measured learning in an undergraduate criminal justice program at an Hispanic Serving Institution bordering Mexico. We estimated the average gains students achieved across core content areas using a technique that can be used by other faculty as part of program assessment. The majority of participants were Hispanic first-generation college students. An independent samples t-test was used to examine differences between freshman- and senior-level students, and the Lovett/Johnson model (2012) model was used to measure student gains using regression analysis. Results indicated that seniors showed meaningful gains at every level. 相似文献

The new science education reform documents call for integration of engineering into K-12 science classes. Engineering design and practices are new to most science teachers, meaning that implementing effective engineering instruction is likely to be challenging. This quasi-experimental study explored the influence of teacher-developed, engineering design-based science curriculum units on learning and achievement among grade 4–8 students of different races, gender, special education status, and limited English proficiency (LEP) status. Treatment and control students (n = 4450) completed pretest and posttest assessments in science, engineering, and mathematics as well as a state-mandated mathematics test. Single-level regression results for science outcomes favored the treatment for one science assessment (physical science, heat transfer), but multilevel analyses showed no significant treatment effect. We also found that engineering integration had different effects across race and gender and that teacher gender can reduce or exacerbate the gap in engineering achievement for student subgroups depending on the outcome. Other teacher factors such as the quality of engineering-focused science units and engineering instruction were predictive of student achievement in engineering. Implications for practice are discussed. 相似文献

Under what conditions do firms benefit from the research efforts of other organizations? 总被引:1,自引:1,他引:0
Although R&D spillovers play a key role in the battle for technological leadership, it is unclear under what conditions firms build on and benefit from the discoveries of others. The study described here empirically examines this issue. The findings indicate that, depending on technological opportunities, firm size and competitive pressure, the net impact of R&D spillovers on productivity can be either positive or negative. Specifically, we find that although spillover effects are positively associated with the technological opportunities that a firm faces, this relationship is reversed when firm size is considered. Whilst external R&D affects large self-reliant firms negatively, its impact on the productivity of smaller firms (who usually introduce incremental innovations that are characterized by a strong reliance on external technologies) is positive, and even higher than that of their own R&D. We also demonstrate that the economic payoff for firms’ own R&D is lower when they face intense competition. In cases of low-appropriability, however, spillover effects are more positive, allowing firms to increase their performance using the inventions of others. 相似文献

IntroductionBased on the hypothesis that there is a substantial rate of adults with prediabetes and undiagnosed diabetes mellitus (DM), our aim was to perform haemoglobin A1c (HbA1c)-based screening in a cohort of Croatian adults and estimate the prevalence of prediabetes and undiagnosed DM according to American Diabetes Association criteria.Materials and methodsThis multi-center, cross-sectional study performed in six Croatian hospitals included 5527 patients aged 40 to 70 years admitted to the Emergency Department or undergoing a primary care check-up. Haemoglobin A1c was measured from leftover whole blood samples using the enzymatic method on either Alinity c or Architect c-series analyser (Abbott Laboratories, Chicago, USA). Haemoglobin A1c between 39-47 mmol/mol was classified as prediabetes, while ≥ 48 mmol/mol as undiagnosed DM.ResultsAfter exclusion of 435 patients with known DM, the final cohort included 5092 patients (median age 57; 56% males). A total of 882 (17.3%) patients had HbA1c values between 39 and 47 mmol/mol. There were 214 (4.2%) patients with HbA1c ≥ 48 mmol/mol. Prediabetes prevalence ranged from 14.2% to 20.5%, while undiagnosed DM from 3.3% to 7.3%, with statistically significant differences among settings (P < 0.001). Age-stratified analysis showed that prediabetes and undiagnosed DM prevalence increase with age (P < 0.001), being 25.4% and 5.8%, respectively, in patients aged 60 to 70 years.ConclusionUnderlying impairment of glucose metabolism was identified in about one in five adults, with significant number of patients with already overt DM. These results should serve as a starting point for further steps directed towards promotion of preventive measures for DM in Croatia. 相似文献

A growing body of literature is focusing on how the collaborations researchers engage in affect their productivity. Most authors have focused on linkages among academic researchers, measuring productivity by the number of papers published in ISI journals. In contrast, the impact of interactions between academic researchers and the business sector on research productivity has been less analyzed. The aim of this paper is to analyze how broadly defined research productivity (papers, new recommendations and new techniques) in agriculture-related fields is affected by the nature of academy-farmers interactions. This latter was approached through two dimensions: the breadth of linkages and their intensity, measured by the duration, in two different modalities (R&D activities and consultancy). Based on original micro data obtained through a survey of researchers working in universities and PRCs in agriculture-related fields, we built three models, one per output, to identify the effect of the nature of interactions on research productivity. The models were estimated with a negative binomial distribution using Maximum Likelihood estimators. We found a positive relationship between interaction with farmers and publishing of papers when interactions are carried out through the R&D modality. We also found that the impact of the nature of interactions on research productivity differs according to the type of research output. The impact is broader in the case of new recommendations than in the other outputs. The production of new recommendations is positively influenced by both the breadth of linkages and their duration through both modalities of interaction (R&D and consultancy). 相似文献
