论《机器人技术》公选课教学改革

为了适应现今社会对大学生要求不断变化,大学的培养模式也在不断改变。由单一型人才培养模式转变为复合型人才培养模式,在高等学校开设《机器人技术》公选课是势在必行的。根据理论和实践的教学经验,文章探讨了一种适应于公选课的《机器人技术》教学改革方案,具有一定的指导作用。     

Connecting strategic orientation,innovation strategy,and corporate sustainability: A model for sustainable development through stakeholder engagement

This paper aims to enhance our understanding of the relationship between organizations' strategic orientation (i.e., instrumental, equidistant, and stewardship) and their innovational strategy (i.e., organizational ambidexterity and open innovation), and this relationship's influence on their sustainability performance. We expected organizations' strategic orientation to influence their innovational strategy and exhibit better corporate sustainability. We focused on 12 different multinational organizations in the Eurozone and found that inbound open innovation acts as a driver for corporate sustainability while simultaneously positively enabling organizations to pursue both financial and social initiatives. After suggesting open innovation as a new corporate sustainability antecedent, we only found empirical evidence of inbound open innovation. However, we would suggest that if organizations incorporated outbound open innovation in their strategy, they could likely improve their corporate sustainability. Also, we found that achieving an equidistant or stewardship orientation paves the way for sustainability to become an integral part of an organization's innovational culture and actualizes the organization's strategic behavior. Our findings further contribute to a deeper understanding of organizations' characteristics as their sustainability commitment grows and as they move from an instrumental to a stewardship orientation and implement an open innovational strategy.     

宁夏农业发展的生态问题与保护治理的投融资机制研究

宁夏农业的发展面临着严重的生态问题,其治理与保护的瓶颈之一就是资金不足。本文在分析了宁夏农地存在的生态问题和原有投资效果的基础下,结合生态保护和治理的特殊性,提出了新的融资模式和投资机制。融资模式可以采用基金会融资模式和准项目融资模式,以保证融资渠道的稳定长效。投资机制上应该考虑到生态退化程度不同的区域采用不同的投资途径以确保资金使用的有效。

西部大开发战略对西部地区碳排放影响效应研究

西部大开发战略在促进西部地区经济增长的同时,也影响了西部地区的碳排放量。为衡量西部大开发战略对碳排放的影响效应,文章收集了我国30个省份1997—2017年的省际面板数据,以Eviews10构建DID模型进行研究分析。发现西部大开发战略在西部地区碳排放绝对量增长的背景下,并未增加西部地区的碳排放量,反而促进了西部地区后发优势的发挥,具有生态友好性;进一步研究发现,西部大开发战略使西部地区碳源结构进一步向煤炭碳源倾斜。西部大开发战略在新时期应促进西部地区技术经济的发展,合理利用西部资源的同时开发新能源,保持生态友好性,促进西部地区经济—生态双赢模式的发展。

自动岩土工程勘察与地基处理问题及解决对策

在建筑工程项目建设过程中,岩土工程勘察为地基设计提供了基础支持,能够为建筑物基础设计、地基处理、施工提供工程地质资料和技术参数。但是,很多建筑企业不注重岩土工程勘察工作,导致实际勘察工作中出现了一系列问题,相关部门需要深入分析这些问题,针对岩土工程勘察和地基处理问题制定相应的解决方法,论文主要分析了岩土工程勘察与地基处理问题及解决对策。     

江苏国内旅游客源市场空间结构研究

以江苏省国内旅游抽样调查资料为基础,运用ADod指标、数值模拟等方法分析了江苏国内旅游客源市场份额分布情况,发现2000—2008年各个年份一级客源市场都占有绝对的主导地位,但有不断下降的趋势;江苏客源地到目的地的平均距离总体上呈现出不断上升的趋势,对远距离客源地的吸引能力在不断的加强;江苏省国内旅游客源市场分布符合距离衰减规律,客源市场在500km以内衰减较快,距离效应比较明显,500km以内的区域的比重占到了60%以上,500—2300km客流量呈现波动减少的特征;江苏国内客源市场的衰减规律遵循幂指数衰减,其距离摩擦指数为1.2095。

Anti‐immigration policy in the destination country and skilled–unskilled wage inequality in a source economy with or without unemployment

This paper is aimed at theoretically examining the consequence of the anti‐immigration policy adopted in the destination country on the skilled–unskilled wage inequality in a source nation using a couple of two‐sector, specific‐factor general equilibrium models in both the presence and absence of unemployment. Emigration requires incurring some capital cost for professional skill formation on the part of every prospective emigrant that adds to the opportunity cost of emigration. The authority of the destination country determines the number of visas to be granted and hence directly controls the magnitude of skilled emigration from the source country. In the migration equilibrium, the expected skilled wage income abroad is equal to the opportunity cost of emigration. In both the presence and absence of unemployment of unskilled labor, the outcome of the policy on the wage inequality crucially hinges on both the magnitude of the fixed cost of emigration and the technological factors. In the specific‐factor Harris–Todaro model, the degree of imperfection in the unskilled labor market is an additional factor. Finally, some policy recommendations have been made for protecting the interest of the poor unskilled workforce.
