数学教学中要注意发散思维能力的培养

发散思维是以一种新的方式去看待一定信息,从而得到独特和非预期结论的一种思维能力.由于发散思维要求思维流畅、灵活、独特,因此,有的心理学家将发散思维与创造性的思维联系起来,希望通过发散思维的激发来培养学生的创造能力.近年的中考也出现了一些利用发散思维能力去解答的题目,但在传统教学中,发散思维的训练一直未受到足够的重视,因此,这方面的研究已成为目前思维研究的重要课题.     

浅谈高中物理教学中发散性思维培养的方法与策略

发散思维是指对同一个问题，沿着不同的方向去思考，从不同角度，不同侧面对所给信息或条件加以重新组合，横向拓展思路，纵向探索研究，逆向反复比较，从而找出多种合乎条件的可能答案、结论或假说的展开性思维形式。在高中物理教学中培养学生的发散性思维，应该从努力营造良好的思维环境、建构发散点两个层面来具体应用这一思维方法与策略。

World oil prices and O.E.C.D. trade balance

This paper develops a theoretical model which postulates that while the drop in oil prices during the 1980s has benefitted O.E.C.D. countries in a way not unlike a favorable productivity shock, the concomitant shift in oil market share from Arab or cartel core petroleum exporting countries to non-Arab or non-cartel core petroleum exporting countries, has provided less benefits to the O.E.C.D. countries than has hitherto been acknowledged. The econometric analysis lends support to the model.     

COST AND QUALITY PERFORMANCE INDICATORS FOR HOME COMMUNITY-BASED CARE SERVICES TO ORPHANS AND VULNERABLE CHILDREN

The encouragement of care of orphans and vulnerable children by non-profit organisations (NPOs) is a major policy response to the HIV and AIDS epidemic in South Africa. The purpose of this article is to present a quality–cost model with five performance indicators for quality and two for costs and to test these against actual performance using data collected from nine rural and urban organisations in 2004 and 2005. Six NPOs had acceptable cost but all had unacceptable quality scores; three had unacceptable cost and unacceptable quality scores. Each rural caregiver had many more orphans and vulnerable children beneficiaries than their urban counterparts but made fewer total visits. As a result, urban beneficiaries received, on average, 3.5 times more visits than their rural counterparts. The results suggest the need for different performance indicators and expectations for rural and urban NPOs and that monitoring and evaluation using the model could improve horne community-based care services.

Excess Liquidity and Inflation Dynamics in China： 1997-2007

The surge in international capital inflows and the remarkable excess liquidity in China between 1997and 2007are examined in the present paper. It is shown that China＇s improved position in terms of foreign exchange purchases, ignited by huge foreign capital inflows, has effectively induced excess liquidity in China. More importantly, by developing an econometric madel for inflation and excess liquidity, the present study demonstrates that excess liquidity has imposed significant pressure on inflation in China over the past 10 years. This finding suggests that excess liquidity in China has not only contributed to the rise in stock prices and the real estate market boom, but also affected the consumer goods market. The potential transmission mechanism of liquidity-driven inflation and policy implications of the findings of this study are discussed.     

Testing for (Efficiency) Catching-up

We used advances in data envelopment analysis (DEA) techniques to examine efficiency scores and investigate the issue of convergence and divergence in a cross-country analysis. Specifically, we used bootstrapping techniques to examine a data set of 52 developed and developing countries. We found that when using the standard DEA model, some of the results were not robust. Further, we broke the sample into groups to examine club convergence. We found that efficiency scores were significantly different between groups and that there was some evidence of convergence of efficiency scores within each group.

Does learning longer improve student achievement? Evidence from online education of graduating students in a high school during COVID-19 period

This paper examines the effect of online learning time on graduating students' test scores in a senior high school. Decisions regarding online education, including those related to participation and learning hours, are endogenous due to both reverse causality and omitted variables. This paper is the result of the natural experiment of the outbreak of COVID-19, which made every student to participate in online education when the spring semester began. In addition, this paper uses a value-added model controlling for the scores that preceded online education, which is a sufficient statistic of students' unobserved ability and motivation. If this cannot completely eliminate the endogeneity problem, it should be able to largely alleviate the problem. The results indicate that: online education has positive but limited impacts on test scores on average, particularly those in the subject of math within the natural sciences track; top-tier students are most positively affected by online education; and the benefits of online education vary among students with different backgrounds. The quantile regression suggests that a 10% increase in online education time raises math test scores by more than 0.25 for the students between the 0.60th and 0.80th quantiles. Surprisingly, it is evident that online learning time has a significant negative effect for some students in certain subjects. Finally, online education neither widens nor narrows the inequality of students' test scores.     

Interdependence between Overseas and Domestic R&D Activities: Evidence from Taiwanese Multinationals

The purpose of the present paper is to examine the interdependence between the overseas and domestic R&D activities of Taiwanese multinational enterprises (MNEs). Because domestic (overseas) R&D activities may enter the overseas (domestic) R&D determination equation as an endogenous right‐hand side variable, the traditional estimation approach will be invalid due to the endogeneity problem. Therefore, it is proposed that the two R&D decisions be estimated using a simultaneous Tobit model. The results in this paper indicate that Taiwanese MNEs that engage in higher levels of domestic R&D activities will engage in overseas R&D activities. Interestingly, it is also found that Taiwanese MNEs increase their overseas R&D activities in developed countries instead of their domestic R&D activities, whereas Taiwanese MNEs that engage in overseas R&D activities in less‐developed countries will raise their domestic R&D activities. As for the other common determinants of the overseas and domestic R&D activities, firm size and the capital–labor ratio are found to be the main factors.     

Pharmaceutical Patents: Incentives for Research and Development or Marketing?

We analyze how a patent‐holding pharmaceutical firm may strategically use advertising of existing drugs to affect research and development (R&D) investments in new (differentiated) drugs, and thereby affect the probability distribution of future market structures in the industry. Within a fairly general model framework, we derive exact conditions for advertising and R&D being substitute strategies for the incumbent firm and show that it may overinvest in advertising to reduce the incentive for an entrant to invest in R&D, thereby reducing the probability of a new product on the market. In a more specific setting of informative advertising, we show that such overinvestment incentives are always present and that more generous patent protection implies that a larger share of the patent rent is spent on marketing, relative to R&D.     

The dynamics of European industrial structure

Has the European integration process lead to increased specialization and what drives changes in countries’ specialization? To address these questions we apply a model that incorporates endowments, technology and increasing returns to scale. Analysis reveals that countries with high capital accumulation have become increasingly specialized in capital-intensive industries; this holds for both human and physical capital. No general tendency towards increased specialization is found with the exception of capital-intensive industries. Analysis indicates scale economies in R&;D at the firm level and that R&;D at the firm level drives productivity and competitiveness. JEL no. C29, F12, O33, O52
