我国教师专业伦理研究综述

教师专业化发展已经成为一种国际趋势，在此背景下各国学者都积极地开展有关教师专业伦理方面的研究工作，我国学 者近二十年来也广泛开展了相关研究工作。从学理研究、建设研究、问题研究、比较研究、各级各类教育研究、教师专业伦理素 养研究以及新颖视角研究等方面全面梳理我国学者的研究成果，在概括成果的基础上，进一步指出研究的不足之此，为今后我 国教师专业伦理方面的进一步研究提供有益参考。     

Logistic模型配合家禽生长资料参数估计方法比较的Monte Carlo研究

本文用Logistic模型配合Monte Cario方法模拟的30个家禽生长资料,以比较Logis-tic模型参数估计的最小一乘法、最小二乘法和minx~2法,以及线性化方法。结果表明:最小二乘法(LS)和最小一乘法结果相当,均优于ininx~2方法;参数估计的线性化方法结果较差,以改良三点法效果较好。     

产业变迁对不同技能劳动力区域选择的影响机制研究CSSCI

本文基于2018年全国流动人口动态监测调查数据,利用多项式Logit和KHB检验方法,从技能差异的角度考察产业变迁,特别是生产性服务业对劳动力区域选择的影响。结果表明,各技能劳动力的区域选择存在显著差异和变化,产业对不同技能劳动力的区域选择存在中介影响,高技能劳动力有更多选择和更高标准。进一步从工资收入、发展空间、生活质量3个维度分析传导机制,发现随着从事生产性服务业劳动力的技能水平不断提高,发展空间和生活质量对其区域选择的作用愈渐增大,中西部地区表现出更大吸引力,主要集中在成渝城市群、长江中游城市群、关中平原城市群。由此可见,基于产业细分和技能差异的考察揭示了中国劳动力区域迁移转变更加具体生动的过程。     

In sight,in mind: Spatial proximity to protest sites and changes in peoples' political attitudes

Occupying public spaces can be an effective tactic for conveying a semantic message of protest and gaining wider support; however, it may also severely disrupt the everyday lives of non-participants and causes a backfire. Therefore, it remains unclear whether and how the occupy movements have shifted political attitudes among the general public. Bringing a social-spatial perspective to the case of the Occupy Central Movement (OCM) in Hong Kong, this study investigates how the attitudinal impact of occupation has varied according to people's spatial proximity to the protest sites. Using two waves of individual-level panel data collected right before and after the OCM and detailed geo-information on the respondents' home addresses and the occupied areas, we apply a difference-in-differences (DIDs) design to identify the causal link between space and attitudes. In addition, propensity score matching (PSM) methods are used to ensure the comparability of nearby and faraway residents. The results show that after the OCM, residents living near the occupied areas not only maintained their support for the pro-democracy camp but also became more liberal as compared to faraway residents. This phenomenon can be explained by the “on-site” effect, which suggests that the direct exposure to protestors' solidarity and the repressive actions of authorities arouse bystanders' sympathy for the protestors and support for their political cause. Such influence appears to be long-lasting and can be evidenced by the local election results after the protest.     

要素结构性变动与房地产市场稳定 ———基于重庆的典型分析

市场要素的结构性变动对房地产市场的稳定影响日益明显。 在明确房地产市场重要支撑因素 的基础上,以重庆为典型样本,利用短动态面板、面板随机前沿分析及面板门槛,系统研究要素结构变动 对房地产市场稳定的影响。 研究发现:当期居民收入对房市稳定是显著作用,房价预期与要素结构变动 也会对房市稳定产生重要影响,且存在区域异质性。 在发达地区,市场预期发挥的作用更突出,欠发达地 区更依赖市场要素结构变化。 当预期房价增长率在 0. 3 左右,其对房市稳定的影响最大。 从单项指标 看,就业人口变化对房地产市场稳定的影响最明显,后依次为住宅用地供应、住房市场存量、金融贷款。 结果表明,要保持房地产市场稳定,夯实经济,提升收入,稳定预期是基础;优化要素投入结构,吸引更多 就业人群是关键,而仅靠增加土地和住宅供应换取房市稳定,并非长久之策。
