在国际贸易中我国粮食产业定价权分析——基于粮食产业链的研究视角

随着我国粮食市场开放程度的提高,我国粮食产业的各个领域都受到国际贸易市场的强烈冲击。由于国内粮食生产、加工、流通各环节的企业对粮食国际贸易定价权的缺失,导致粮食产业整体利益受损。从粮食产业链的角度对中国粮食参与国际贸易定价权缺失情况进行分析,并提出改进对策,以在市场开放的前提下提高我国粮食产业的竞争力。

当代大学生诚信缺失现状、成因及教育对策研究

诚信是中华民族的传统美德,是当代大学生仍要继承并发扬的优良传统之一,然而,近些年来日益凸显的大学生诚信危机已引起了社会的普遍关注。在界定大学生诚信缺失行为特征的基础上,从学习、经济、人际交往等方面指出了大学生普遍存在的诚信缺失行为,并从社会、教育、制度、思想等方面总结了原因,提出优化环境是解决大学生诚信缺失的前提;加强教育是解决大学生诚信缺失的关键;完善机制是解决大学生诚信缺失的保障。

Evaluating the power of Minitab's data subsetting lack of fit test in multiple linear regression

Minitab's data subsetting lack of fit test (denoted XLOF) is a combination of Burn and Ryan's test and Utts' test for testing lack of fit in linear regression models. As an alternative to the classical or pure error lack of fit test, it does not require replicates of predictor variables. However, due to the uncertainty about its performance, XLOF still remains unfamiliar to regression users while the well-known classical lack of fit test is not applicable to regression data without replicates. So far this procedure has not been mentioned in any textbooks and has not been included in any other software packages. This study assesses the performance of XLOF in detecting lack of fit in linear regressions without replicates by comparing the power with the classic test. The power of XLOF is simulated using Minitab macros for variables with several forms of curvature. These comparisons lead to pragmatic suggestions on the use of XLOF. The performance of XLOF was shown to be superior to the classical test based on the results. It should be noted that the replicates required for the classical test made itself unavailable for most of the regression data while XLOF can still be as powerful as the classic test even without replicates.     

诚信缺失与对策研究

诚信原则是民事活动最核心、最基本的原则,当前大学生群体在人际交往、学术研究,就业求职以及助学贷款等活动中存在诚信缺失现象,其产生的主要原因是由于家庭学校诚信教育中的缺失,社会转型及市场经济的负面影响和社会信用管理制度的不完善造成的。培养大学生的诚信素质,既要靠家庭和学校教育,完善和健全他们的公民人格与公民意识,也要靠建立相应的制度来约束。     

我国教育投资短缺的原因及对策研究

教育投资短缺已成为制约我国教育发展的一大障碍。本文分析了造成教育投资短缺的原因，认为教育供给不足，需求无限以及教育投资效率低下是其主要原因，而解决这一问题的基本对策是增加教育供给，抑制需求，提高教育投资效率。     

生命教育：高校德育的缺失与补救

当前发生在大学生身上的意义虚无、生命困顿和践踏生命等现象,已经成为当前高校比较突出和困惑的问题,高校德育对此显得无能为力,这与高校德育缺乏对生命教育的关注密切相关。生命教育不是独立于德育之外的教育形式,但是作为高校德育的价值取向、内容整合和方法论依据,融入到高校德育的实践,是对高校德育生命价值缺失的补救,也是提高高校德育人文关怀的着力点。     

大学生诚信教育探讨

诚信是中华民族的传统美德,是中国传统文化中历来强调的道德信条,是大学生应具备的道德品质。作为思想道德建设前沿阵地的高等学校,诚信问题显得更为迫切。大学生诚信缺失给高校教育工作者提出了新的课题。论文从分析大学生诚信缺失原因入手,例举大学生诚信缺失的具体表现,并且提出强化诚信法治效应、坚持诚信认知和诚信行为的结合、开展诚信教育、建立信用指标体系、增大失信成本、营造诚信氛围等对策。     

Empowerment in social work: an individual vs. a relational perspective

Social workers with only an individualistic understanding of empowerment will easily end up as moralising agents rather than as facilitators for their clients. It is in the complex interaction between a given socio-material situation and the individual capacity to interpret and act that one finds the key to an empowerment worthy of its name. This presupposes two things: that social workers have as a part of their education theoretical knowledge about organisational structures, and that they themselves have been empowered in ways that give them practical competence to act in relation to situations. They need the competence to identify the complexities of interests and power relations in society. The implication of such a recogni-tion should be clear for the education of social workers: the ideology of empowerment has to be contextualised . To discuss this topic the author makes a distinction between an individua-listic and a relational perspective and between social problems conceived of as a 'lack of money' vs. a 'lack of meaning'.
