对大学毕业生就业失信行为的审视

失信在当今社会、经济生活中已成为较为突出的矛盾和问题 ,就连大学毕业生在求职过程中也表现出失信行为。如“注水简历”、“伪造证书”、“随意违约”等 ,过早地闪现了诚信危机的寒光 ,现状堪忧 ,这不能不引起全社会的关注。其原因主要有就业形势严峻 ;社会失信行为的负面影响 ;社会、学校、家庭诚信教育体系的缺失等。大学毕业生在求职过程中惟有自身进行反省 ;学校建立起良好的诚信育人环境 ;主管部门加快健全信用机制 ;用人单位调整好选才标准 ;媒体舆论等社会力量共同营造诚信的良好氛围 ,才能实现诚信就业。     

启蒙对话与个人发现——重读鲁迅的《野草》

从启蒙话语建构和知识分子自我发现的角度探讨了新文化运动的低落如何影响了鲁迅<野草>的写作.启蒙话语的建构是以有效的对话关系为基础的,因为缺乏共同的精神自觉,知识分子与一般民众之间始终无法形成有效的对话关系.启蒙话语既然难以完成建构,知识分子或退守,或复仇,或沉默,不过是发现和体认了自我深深的无力感,正是这种心理造成了<野草>黯淡、低沉的情绪基调.     

对解决大学毕业生工作经验问题的思考

大学毕业生就业难的重要原因之一是缺乏用人单位强调的“实践经验”。本文认为，首先，在变化加剧的时代一个人的经验依赖，特别是专业技术上的经验依赖是有限的，用人单位更应当考察大学生的“可雇佣性”。其次，解决大学毕业生初次就业的社会实践和工作经验问题是高校、用人单位和学生三方共同的责任。

遗失物拾得人权利与义务失衡的反思——兼评《物权法草案》全民征求意见稿

对大陆法系和英美法系各国关于遗失物拾得制度的比较和对我国遗失物拾得制度的历史考察表明,古今中外关于遗失物拾得制度的规定,既保护遗失人的利益,也重视对拾得人权利的维护;不仅规定了拾得人的必要费用的请求权,也规定了拾得人的报酬请求权和附条件地取得遗失物所有权的权利。因此,建议我国物权法应顺应时代潮流,转变观念,在为拾得人设定义务的同时,也应赋予其一定的权利,弘扬拾金不昧的传统美德,以体现法律的平等、正义价值和精神。     

噪声子空间法的宽频段分析

分析了均匀线阵噪声子空间法在宽频段多信号环境下存在的主要问题:不能保证频率和空间方向矩阵的列矢量线性独立、使用方向矢量搜索方法时不能同时正确估计多个信号到达方向两个问题。分析所得结论对于探索利用一维(1—D)方法实现宽频段多信号同时测向具有有益的参考价值,计算机模拟结果证明了本文分析的正确性。     

阵列信号单信道处理技术

阵列信号处理已广泛应用于许多电子系统中，如微波无源比幅测向系统等，但通道间的振幅和相位的不平衡常常引起较大的测向误差。为了匹配通道间的振幅和相位平衡，可利用卫星通信中的多址联接技术（如ＦＤＭＡ、ＴＤＭＡ或ＣＤＭＡ）构成单信道处理系统来代替多信道系统。文中详细地研究了ＣＤＭＡ单信道系统，建立了系统模型，分析了系统特性，模拟结果证明了这种单信道理论和技术的可行性。     

Generalized phase I-II designs to increase long term therapeutic success rate

Designs for early phase dose finding clinical trials typically are either phase I based on toxicity, or phase I-II based on toxicity and efficacy. These designs rely on the implicit assumption that the dose of an experimental agent chosen using these short-term outcomes will maximize the agent's long-term therapeutic success rate. In many clinical settings, this assumption is not true. A dose selected in an early phase oncology trial may give suboptimal progression-free survival or overall survival time, often due to a high rate of relapse following response. To address this problem, a new family of Bayesian generalized phase I-II designs is proposed. First, a conventional phase I-II design based on short-term outcomes is used to identify a set of candidate doses, rather than selecting one dose. Additional patients then are randomized among the candidates, patients are followed for a predefined longer time period, and a final dose is selected to maximize the long-term therapeutic success rate, defined in terms of duration of response. Dose-specific sample sizes in the randomization are determined adaptively to obtain a desired level of selection reliability. The design was motivated by a phase I-II trial to find an optimal dose of natural killer cells as targeted immunotherapy for recurrent or treatment-resistant B-cell hematologic malignancies. A simulation study shows that, under a range of scenarios in the context of this trial, the proposed design has much better performance than two conventional phase I-II designs.     

Editors' Introduction

For the professional middle class in information industries, “working from home” is an increasingly common feature of the employment landscape, resulting from the affordability and portability of information and communication technologies (ICTs). The phrase invokes a sense of freedom from the banality of the traditional office, offering flexibility in both working hours and location when other commitments prevail. In recent debates in Australian politics, working from home is also offered as an empowered choice for women who seek to combine paid work and childcare duties, thereby consecrating a preferable version of (post)feminist subjectivity suited to neoliberal economics and ideologies. This paper shows how these subjectivities have been represented in recent ICT advertising for two purposes: firstly, to highlight the role of mainstream media in normalising preferred uses of new media technology for work purposes; and secondly, to note how this process contributes to wider discourses limiting the aspirations of middle-class feminist politics to an individual level. In doing so, the paper seeks to question the ethical horizon of new media advertising as well as the feminist and labour politics upon which its appeal relies.     

学龄前儿童抚育模式的转型与工作着的母亲

在中国计划经济向市场经济的转型过程中,城市学龄前儿童抚育模式也在转型。计划经济时代,学龄前儿童抚育工作作为＂公家事务＂,使工作着的母亲获得了可能的职业发展空间。随着市场经济的发展,学龄前儿童的抚育模式转向以市场理性选择为主的家庭和个人责任,独生子女政策更进一步强化了母亲与孩子成长优劣间的关系,工作着的母亲深感压力,母亲角色与职业角色间的冲突加剧。应当建立支持学龄前儿童抚育的国家制度,倡导公共托儿所和幼儿园的重新建设,解决职业女性的后顾之忧。
