Using local linear kernel smoothers to test the lack of fit of nonlinear regression models

Herein, we propose a data-driven test that assesses the lack of fit of nonlinear regression models. The comparison of local linear kernel and parametric fits is the basis of this test, and specific boundary-corrected kernels are not needed at the boundary when local linear fitting is used. Under the parametric null model, the asymptotically optimal bandwidth can be used for bandwidth selection. This selection method leads to the data-driven test that has a limiting normal distribution under the null hypothesis and is consistent against any fixed alternative. The finite-sample property of the proposed data-driven test is illustrated, and the power of the test is compared with that of some existing tests via simulation studies. We illustrate the practicality of the proposed test by using two data sets.

林庚白对宋诗派理论的反思与改造及其古典诗歌创作观

林庚白是南社的重要作家之一,研究近代文学的学人往往简单地视林庚白为宋诗派成员,但事实上宋诗不能涵盖林氏一生诗歌的情感内容和艺术风貌。从早年对同光体的追慕到后来对宋诗派的反叛和超越,林庚白对同光体宋诗派理论的内省与改造体现在藉诗写史的自觉性,情绪与情感的现代性以及以社会主义者之身世与怀抱而为诗三个方面,为传统诗词创作注入了新的精神　　气质和思想内涵。其五四以后的诗作也显示了旧体形式的诗歌在主动顺应历史潮流,渗入时代精神的条件下的内在生命力和创作实绩,不应为近现代文学研究所忽视。

和谐社会伦理:对革命道德教化理念的解构与超越——革命道德教化的现代性道德价值理念审理

中国现代性道德教化是一项未竟的事业。革命道德教化理念是宝贵的精神财富,但是,以现代性道德价值理念来分析,革命道德是一种“信念伦理”,革命道德教化作为“非常时期”的道德教化活动,不能实现对启蒙道德教化的超越,与之形成了现代性道德教化的某种断裂。透析革命道德教化的现代性断裂现象,对当代道德教化有着重要启示。“和谐社会”伦理是和谐社会的价值基础,是当代道德教化的核心理念,是对革命道德教化理念的超越。

Firm-level training in local economic systems: Complementarities in production and firm innovation strategies

The paper presents a conceptual review over the main aspects concerning the role of human capital investments and training activities within production processes, followed by empirical evidence on two local economic systems in Northern Italy, based on recent survey data. Theoretical and empirical considerations are brought together in order to provide new insights on the role of training and the factors associated to training activities at firm level.The potential driving factors of training here analysed compounds structural characteristics, labour demand dynamics, human resource management practices, workforce features, and firm performances. We observe that training activities emerge positively associated with high-performance practices, innovative labour demand features, workforce skill level, firm size, and are affected by labour flexibility in various directions. Empirical evidence confirms most previous results but also adds further important insights. The analysis suggests that a widening gap, between few innovatively evolving and many stagnant firms, could characterise the future dynamics of the Region. The high relevance of structural variables, labour demand factors and HRM/innovation practices shows that regional industrial policies and labour policies should be jointly implemented for increasing potential firm productivity. This is a key concern for the current debate on local systems economic development in the European and Italian environment.     

从经济学视角谈科学育才之路

在现阶段高校毕业生面临着社会对他们的有效需求不足的问题,从而必须面对社会对高素质人才的需求同高校毕业生供给相对过剩这一结构性供需矛盾。本文从经济学角度分析产生这种矛盾的原因,进而提出只要高校学生工作措施得当,政策有针对性,就有可能缓解上述供需矛盾。
