邓小平农村改革思想的农民主体性特征及其时代意义

进一步研究邓小平农村改革思想及其时代意义,是当前我国进行新一轮农村改革的必然要求。本文从分析邓小平农村改革思想人手,指出其最显著的特征在于始终围绕农民为主体,同时指出目前我国农村改革所面临的严重的主体缺失困境,对其原因进行剖析,并提出了相应的策略。     

论船舶融资担保法律体系之构建

航运业和造船业的发展离不开金融业的融资支持。当前世界经济进入调整时期,如何设置船舶融资担保体系以确保金融安全非常重要。除船舶抵押权外,银行还可选择信用担保、收益让与担保等辅助担保形式确保贷款的安全。     

学术注释千古事,循规尊贤始有成——对李大钊论著中四个外国人名注释及相关问题的再探讨

李大钊论著中包含大量当代读者所不熟悉的外国人名,如何把这些外国人物注释出来,帮助读者读懂李大钊的文章,是一个难度很大的课题,稍有不慎或想当然,就会造成误注,从而误导读者。《新版〈李大钊全集〉注释疏证》中对鲍德荫、司铁特、古里天森等外国人物的注释错误很典型的反映了这方面的问题。要避免类似的错误,准确注释李大钊,就必须谨守规范,辨清史实,探析研究。     

文艺学中内容/形式范畴述论(1900～1949)

在20世纪前50年.形式一词从传入到学界对它的运用并专论内容和形式的关系,从不成熟到成熟,虽处在启蒙救亡的大语境中,却在学理上达到了令后50年惊叹的成就,给后世留下了宝贵的理论资源.尤其是向培良对这一对范畴的研究,既反对题材决定论,又反对单纯追求技巧的形式主义;既赞成内容与形式的不可分,两者都不能单独存在,又在整个的艺术创造活动中研究内容向形式的动态转化过程.但后50年学界对此并没有好好继承,究其原因,除了新中国成立后在文艺界长期贯彻<讲话>精神,政治倾向压倒学理倾向之外,也和学界对这些成果有意或无意的忽视有关.     

论休谟的对象的空间表象观

休谟的空间理论及其心理原子主义表明,构成空间表象的最小的不可分的原子印象之间不存在实存的因果联系,这导致对空间对象的表象不可能.体谟的这些思想对于理解康德如何回答体谟的问题具有根本意义.     

Ambidextrous Organizational Culture,Contextual Ambidexterity and New Product Innovation: A Comparative Study of UK and Chinese High‐tech Firms

Contextual ambidexterity is of paramount importance for new product innovation and organizational success, particularly in high‐tech firms operating in a dynamic environment. Whilst it is recognized that contextual ambidexterity is grounded in organizational culture, existing research has not crystallized what kind of organizational culture enables contextual ambidexterity and consequently new product innovation. In this paper, drawing on data from 150 UK and 242 Chinese high‐tech firms, we conceptualize ambidextrous organizational culture as a higher‐order construct consisting of organizational diversity and shared vision, and examine its impacts on contextual ambidexterity and consequently on new product innovation outcomes. Using structural equation modelling, we find significant relationships between ambidextrous organizational culture, contextual ambidexterity and new product innovation outcomes; contextual ambidexterity mediates the relationship between ambidextrous organizational culture and new product innovation outcomes. Our findings also suggest that the above relationships are robust in the UK–China comparative research context, and that contextual ambidexterity and new product innovation outcomes are dependent on business unit level heterogeneity (i.e. ambidextrous organizational culture and research and development strength) rather than industry or cross‐cultural differences.     

The empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior under Stein's loss function

For the hierarchical Poisson and gamma model, we calculate the Bayes posterior estimator of the parameter of the Poisson distribution under Stein's loss function which penalizes gross overestimation and gross underestimation equally and the corresponding Posterior Expected Stein's Loss (PESL). We also obtain the Bayes posterior estimator of the parameter under the squared error loss and the corresponding PESL. Moreover, we obtain the empirical Bayes estimators of the parameter of the Poisson distribution with a conjugate gamma prior by two methods. In numerical simulations, we have illustrated: The two inequalities of the Bayes posterior estimators and the PESLs; the moment estimators and the Maximum Likelihood Estimators (MLEs) are consistent estimators of the hyperparameters; the goodness-of-fit of the model to the simulated data. The numerical results indicate that the MLEs are better than the moment estimators when estimating the hyperparameters. Finally, we exploit the attendance data on 314 high school juniors from two urban high schools to illustrate our theoretical studies.     

Modeling the Adenoma and Serrated Pathway to Colorectal CAncer (ASCCA)

Several colorectal cancer (CRC) screening models have been developed describing the progression of adenomas to CRC. Currently, there is increasing evidence that serrated lesions can also develop into CRC. It is not clear whether screening tests have the same test characteristics for serrated lesions as for adenomas, but lower sensitivities have been suggested. Models that ignore this type of colorectal lesions may provide overly optimistic predictions of the screen‐induced reduction in CRC incidence. To address this issue, we have developed the Adenoma and Serrated pathway to Colorectal CAncer (ASCCA) model that includes the adenoma‐carcinoma pathway and the serrated pathway to CRC as well as characteristics of colorectal lesions. The model structure and the calibration procedure are described in detail. Calibration resulted in 19 parameter sets for the adenoma‐carcinoma pathway and 13 for the serrated pathway that match the age‐ and sex‐specific adenoma and serrated lesion prevalence in the COlonoscopy versus COlonography Screening (COCOS) trial, Dutch CRC incidence and mortality rates, and a number of other intermediate outcomes concerning characteristics of colorectal lesions. As an example, we simulated outcomes for a biennial fecal immunochemical test screening program and a hypothetical one‐time colonoscopy screening program. Inclusion of the serrated pathway influenced the predicted effectiveness of screening when serrated lesions are associated with lower screening test sensitivity or when they are not removed. To our knowledge, this is the first model that explicitly includes the serrated pathway and characteristics of colorectal lesions. It is suitable for the evaluation of the (cost)effectiveness of potential screening strategies for CRC.     

The disaster relief and social work after the Wenchuan earthquake in Mainland China

ABSTRACT

This paper mainly focuses on the development of disaster social work in Mainland China and the intervention of social work in disaster relief. Before the Wenchuan earthquake and in the initial stage of post-earthquake, disaster social work was mainly based on individual psychotherapy; from the earthquake to the year of 2012 in which post-earthquake recovery and reconstruction was completed, the disaster relief began to emphasise community building and integration, while the basic framework for disaster social work was also established. Social workers begin to explore the new mode of developmental and localised disaster social work. By combining with the practical experiences from disaster social work, this paper tries to highlight the dilemmas confronting disaster relief in Mainland China and put forward some corresponding countermeasures and suggestions, which could improve the future disaster relief system in Mainland China.
