素质为本人性提升全面发展——对高职院校加强思想品德和人文素质教育的思考

近20年来,我国高等职业教育得到了飞速发展,已进入内涵建设的关键时期.当前,我国的高职教育理念存在误区,普遍存在重技能、轻素质,重智育、轻德育的“偏科”现象,加强思想品德和人文素质教育势在必行.高职院校必须转变教育观念,把“做事”和“做人”结合起来,提高学生的综合素质,实现“能力本位”向“素质本位”转变,从而真正培养出德、智、体、美全面发展的高素质技术技能型人才.     

Do not swipe the small stuff: A randomized evaluation of rules of thumb-based financial education

We perform the first rigorous test of a rules of thumb-based approach to financial education on consumer behavior and outcomes. We test two rules of thumb that are targeted at reducing credit card revolving and deliver them in a randomized fashion via e-mail, online banner, and physical mailer. Using monthly administrative data and pre and postintervention credit data on almost 14,000 consumers, we find that the “Do not swipe the small stuff” rule of thumb reduces participants' targeted credit card balance by an average of 2% at a cost of around $0.50 per person. The “Credit keeps charging” rule shows a decline as well but the impact is not significant.     

Kicking a crude habit: diversifying away from oil and gas in the twenty-first century

Abstract

This article investigates the correlates of diversification away from oil and natural gas dependence in the context of the twenty-first century resource boom (and bust). In a sample of 40 oil- and gas-dependent economies, the majority showed significant sectoral diversification of GDP, but exports remained highly concentrated in fuel exports. Regression analysis indicates that countries that began the boom with higher levels of oil and gas dependence, poorer countries, and those with significantly larger- or smaller-than-average populations were more successful in diversifying their GDP during the commodities boom. Governance matters – more effective, capable bureaucratic structures are associated with greater GDP diversification away from oil and gas – though the effects are not uniformly positive. For any given level of government effectiveness, stronger rule of law is associated with less GDP diversification. Education appears to affect GDP and export diversification differentially. Consistent with endogenous growth theory, countries with more educated populations saw greater growth in their nonresource sectors than countries with less educated populations, though education is associated with greater export concentration. Internal economic diversification in the twenty-first century has been less a matter of policy formation and implementation, and more a matter of factors that shape the policy-making environment.     

Thinking critically about critical thinking: Assessing critical thinking of business students using multiple measures

Critical thinking is a skill that potential employers expect all graduates to possess. Hence, most business management programs consider critical thinking as an important student learning goal. Unfortunately, there is ambiguity about how to best assess critical thinking, both as a skill and a learning outcome. The authors empirically demonstrate how they measure the critical thinking ability of their students in different settings, and how their critical thinking ability improves as they progress through the business program.     

COMPARING PPP WITH TRADITIONAL PROCUREMENT: THE CASE OF SCHOOLS PROCUREMENT IN IRELAND

Advocates of public‐private partnerships (PPPs) argue that they can deliver public infrastructure more efficiently than traditional procurement through timelier completion and superior value for money. Despite these claims comparative analysis of the performance of both procurement methods has received scant attention in the PPP literature to date. This paper addresses this issue by providing an in‐depth, case‐based comparison of PPP versus traditional procurement in the schools sector in Ireland. Through detailed semi‐structured interviews with key stakeholders and an examination of the available documentation, we assess whether the key objectives of using PPP have been achieved. Overall, we find no evidence that PPP leads to faster delivery of infrastructure when the overall procurement process from contract notice to delivery is accounted for. In addition, we find only limited evidence to suggest that PPP results in better value for money.     

基于SARIMA-SVR组合模型的 空气质量指数预测

空气质量指数(AQI)在波动中既具有整体的时间序列线性特征和明显的季节性波动周期,又具有多种因素影响的不确定性,为了提高AQI的预测精度,基于Ri386 3.3.3和Matlab R2014a两种编程软件,提出了一种同时具有线性和非线性的复合特征的时间序列预测模型——SARIMA-SVR组合模型。以太原市2014年1月—2019年7月的AQI月均值数据为基础,利用SARIMA时间序列模型进行线性预测,利用SVR模型对残差进行非线性预测,加和得到组合预测模型的预测结果,分析比较SARIMA,SVR和SARIMA-SVR这3种模型的预测结果和平均绝对百分比误差。结果表明,组合预测模型发挥了2种模型各自的优势,相较于单一预测模型的预测结果而言,其预测精度更高,稳定性更好。通过此模型得到的空气质量预测结果不仅可为人们的日常生活提供指导,而且可为大气污染的防治工作提供科学依据和借鉴意义。     

CASH TRANSFERS,INTERGENERATIONAL MOBILITY,AND THE PROCESS OF DEVELOPMENT

We examine how cash transfers affect an individual's education investment, intergenerational mobility, and economic growth. We find that providing larger transfer amounts to higher ability children is desirable to foster growth if the economy has relatively low wage inequality.     

Will elders provide for their grandchildren? Unconditional cash transfers and educational expenditures in Bolivia

We take advantage of repeated cross‐sectional household surveys and a sharp discontinuity created by the introduction of an unconditional cash transfer to elders in Bolivia, to evaluate its impact on educational expenditures on children within a household. We find positive and significant impacts of the program at the aggregate level. We also find that the program has stronger effects on indigenous populations as well as on female and rural populations. Our results are robust to a series of falsification tests, survey structure, model specification, and estimation methods.
