学术期刊属性研究

在编辑传播学界关于学术期刊属性的研究上,普遍存在着一个突出的问题,这就是论者们几乎不假思索地认为“学术期刊是商品”。我们认为,这是一个很大的误区,这种认识在理论上是错误的,在实践上是有害的。首先,“学术期刊商品论”是自相矛盾的;其次,“学术期刊商品论”与马克思主义经济学是相悖的;再次,“学术期刊商品论”与普遍存在的事实是恰恰相反的。学术期刊和学术事业是一项创新的事业,它关系一个国家的生存安危,对此,江泽民同志曾经反复强调,创新是一个民族进步的灵魂,是国家兴旺发达的不竭动力之源。因此,对待学术和学术期刊事业应当像对待军队、警察机构一样,不能也不可能使其商品化,学术期刊应该走自己的健康发展之路。     

Equality Bargaining: Where,Who, Why?

It is common to identify a role for trade unions in combating sex inequality at work through collective bargaining. This article uses a survey of paid union officers to identify the context in which equality bargaining by unions is likely to occur, using the specific issue of bargaining on equal pay. It concludes that equality bargaining is a function of women’s voice within unions, the characteristics and preferences of bargainers themselves and of a favourable public policy environment. Bargaining on equal pay is also more likely in centralized negotiations that cover multiple employers.     

BAYESIAN SUBSET SELECTION AND MODEL AVERAGING USING A CENTRED AND DISPERSED PRIOR FOR THE ERROR VARIANCE

This article proposes a new data‐based prior distribution for the error variance in a Gaussian linear regression model, when the model is used for Bayesian variable selection and model averaging. For a given subset of variables in the model, this prior has a mode that is an unbiased estimator of the error variance but is suitably dispersed to make it uninformative relative to the marginal likelihood. The advantage of this empirical Bayes prior for the error variance is that it is centred and dispersed sensibly and avoids the arbitrary specification of hyperparameters. The performance of the new prior is compared to that of a prior proposed previously in the literature using several simulated examples and two loss functions. For each example our paper also reports results for the model that orthogonalizes the predictor variables before performing subset selection. A real example is also investigated. The empirical results suggest that for both the simulated and real data, the performance of the estimators based on the prior proposed in our article compares favourably with that of a prior used previously in the literature.     

洋桔梗叶盘高频率不定芽诱导的初步研究

采用正交设计法研究了细胞分裂素ZT,生长素NAA,培养基pH值和光照强度对洋桔梗叶盘不定芽诱导的影响.结果表明,实验的4个因子对洋桔梗叶盘不定芽都具有极显著的诱导作用,最佳培养基和培养条件为:MS ZT 0.5 mg/L NAA 0.01 mg/L,培养基pH值为6.3,光照强度为3000 lx.该处理中每叶盘再生不定芽数平均达9.41个.     

李贺和比喻

李贺的比喻和一般比喻差别很大,他经常颠倒喻词和被喻词之间的关系,给人带来震撼。这种比喻方法,不仅表现了李贺心中万物平等的思想,也展现了迥异现实的另一世界的景象。

江泽民同志于 2 0 0 0年 6月在全国党校工作会议上的讲话 ,充满了实事求是的精神和深刻的辩证思维风格 ,体现了鲜明的时代特色。他对新时期干部德才基本要求所作出的新的规定 ,是对马克思主义人才理论的极大丰富。他提出的“重发现同时重培养”的原则、“使用、培养同一论”以及“德才具体说”、“辩证的台阶、资历观”等 ,是对传统的人才理论的突破和对马克思主义人才学说的丰富和发展     

分权制衡:公司法人治理结构的核心——对我国国企改革中公司法人治理结构的法理分析

国有股权的单一化和集中化是国有企业公司法人治理结构极不规范和完善的深刻根源 ,而缺乏有效的监督机制则又是其直接原因。国企公司化改造过程中首先必须调整国企的股权结构 ,平衡各股之间的利益关系 ,并确立完善的监督机制 ,实现产权主体的制衡     

The Experience of Gender Change in Public Sector Organizations

The state has a twofold relationship to gender change in society, through its overall steering capacity and through the gendered character of its constituent agencies. It is therefore important to understand the experience of gender change in state organizations. The findings from a study of gender relations in ten public‐sector worksites in New South Wales, Australia are presented. There is a widespread consciousness of gender change linked with new labour processes, restructuring and new patterns of management. These changes are uneven and limits to change are visible. Gender is recognized as an organizational problem in specific circumstances, most visibly where men’s resistance to change appears. A number of mechanisms limit the consciousness of gender as a problem. Several trends, including the current strength of neo‐liberalism, converge to make the gender‐neutral workplace the principal goal of gender reform in the public‐sector workplace. This, however, limits the state’s steering capacity in regard to societal gender relations.     

论宪法的平等保护原则

平等和禁止歧视是现代人权法制的支柱。在国际社会,平等作为人权保障的基本原则,分为法律面前的平等和法律的平等保护,既约束法律适用机关,也限制法律制定机关。而且在美、印等国的宪法判例法中,平等保护原则已有了针对不同的歧视理由分别适用的严格审查标准、中级审查标准和宽松审查标准。在中国,自古以来仅主张法律面前的平等,忽视了法律的平等保护。通过修改宪法和制定专门的人权法,确认平等保护原则,确立适用平等保护原则的底线标准,并通过可操作性的违宪审查制度保障其实施。     

Changing Gender: The Discursive Construction of Equal Opportunities

This article provides a discursive perspective on the dilemmas of sameness and difference feminisms and their consequences for change projects. It explores how equal opportunity officers dealing with gender issues and introducing equality legislation in practice construct the meaning of equal opportunities. The analysis of the interpretative repertoires and ideological dilemmas drawn upon in ten interviews shows the highly context‐specific use of four different repertoires constructing gender equality: the sameness, difference, bandwidth and deconstructive repertoire. Interpreting the shifts between repertoires from the perspective of the ideological dilemma, new avenues for change are explored. The article concludes that the simultaneous use of all possible theoretical perspectives might be a worthwhile objective.
