何为“隐含作者”?

隐含作者是韦恩·布思在《小说修辞学》(1961)中提出来的一个重要理论概念。四十多年来,这一概念在国际叙事研究界被广为阐发应用,产生了很大影响。这一貌似简单的概念,实际上既涉及作者的编码又涉及读者的解码,涵盖了作者与读者的交流,然而西方学界却对之加以单向的理解,这引起了不少争论和混乱。西方学界的误解又可能在一定程度上导致了布思本人在近作中对这一概念自相矛盾的论述。本文追根溯源,阐明这一概念的实质内涵,探讨其在历史上不同走向的变义,旨在纠正误解,梳理混乱,以便更清晰地看到其历史价值和现实意义,并更准确地把握作者、文本与读者之间的关系。     

粮食收储制度改革对家庭农场保费支出的影响

作为深化农业供给侧结构改革的关键举措,以取消玉米临时收储制度为先导的粮食收储制度改革一定会引起粮食生产者的响应和行为调整,规模化的家庭农场更是如此。依据这样的假设,基于家庭农场购买保险的事实,利用实证检验方法对粮食收储制度改革的政策效应进行评价。通过全国家庭农场监测2016年和2017年粮食类家庭农场两期面板数据,建立DID双重差分模型进行政策效应估计,计量结果表明:在控制其他条件不变的情况下,2016年在东北三省及内蒙古地区开展的粮食收储制度改革确实导致了这些地区粮食类家庭农场2017年保费支出的显著增加。这一研究发现再次印证了家庭农场的市场主体特征,据此提出应在深化粮食收储制度改革的同时,积极推动农业保险升级创新,以更好适应粮食生产主体的需求。     

供应商管理库存环境下的合作合约

为了克服信息扭曲和牛鞭效应,许多企业采用了供应商管理库存。由于利益和激励机制的冲突：一方面,销售商为了提高服务水平,希望供应商在仓库中多存货;另一方面,由于库存剩余的风险,供应商不愿在仓库中多存货,供应商管理库存环境下,双边际效应同样存在。本文在需求是随机时研究供应商管理库存的协调与合作问题,提出几个使供应链达到合作的合约。     

浅析杰克·伦敦小说《铁蹄》中的“二元视角”

杰克·伦敦的小说《铁蹄》因其表现革命主题而在文学史上享有很高的地位。评论界在抬高作品革命主题的同时,却贬低了作品的艺术价值,忽视了二元视角叙事模式的运用,从而也影响了对作品主题的理解和认识。因此,为了更进一步理解该作品的思想价值和艺术特征,对作品中二元视角叙事模式做出研究是相当必要的。。     

宽带数字接收机的高效FPGA设计

在FPGA中实现了一种高效的宽带数字接收机,采用坐标旋转数字计算机算法实时产生数控振荡器数据,提高了接收机设计的灵活性。二次变频的接收机结构和四倍抽取的多相滤波结构减少了接收机的运算量,降低了接收机的资源消耗。FPGA中的仿真结果证明了该方法的高效性和实用性。     

Repetitive group sampling plan based on the process capability index for the lot acceptance problem

An acceptance sampling plan is a method used to make a decision about acceptance or rejection of a product, based on adherence to a standard. Meanwhile, process capability indices (PCIs) have been applied in different manufacturing industries as capability measures based on specified criteria which include process departure from a target, process consistency, process yield and process loss. In this paper, a repetitive group sampling (RGS) plan based on PCI is introduced for variables’ inspection. First, the optimal parameters of the developed RGS plan are obtained considering constraints related to the risk of consumers and producers and also a double sampling plan, a multiple dependent state sampling plan and a sampling plan for resubmitted lots have been designed. Finally, after the development of variable sampling plans based on the Bayesian and exact approach, a comparison study has been performed between the developed RGS plan and other types of sampling plans and the results are elaborated.     

Battling the Tiger Mother: Pre‐School Reform and Conflicting Norms of Parenthood in Singapore

This article explores pre‐school reform and shifting norms of parenthood in Singapore. Whereas current education reforms in many Western countries focus on improving academic performance, pre‐school reform in Singapore de‐emphasises academic learning and urges parents to adopt ‘relaxed’ parenting practices. Analysing the position of parents in this process, we show, however, that the outcomes of this reform project are highly ambivalent. Reform makers view parents’ mindset as the main obstacle to reform, while parents experience pre‐school reform itself as prompting inconsistent messages. To account for the disorientation that this creates among parents, we draw on Bateson's concept of double bind.     

Conditional residual lifetimes of coherent systems under double monitoring

In this paper, we obtain a mixture representation for the reliability function of the conditional residual lifetime of a coherent system with n independent and identically distributed (i.i.d.) components under double monitoring. We suppose that at time t₁, j components have failed while at time t₂ the system is still alive. Based on these mixture representation, we then study stochastic comparisons of the conditional residual lifetimes of two coherent systems with independent and identical components.     

Improvement over variance estimation using auxiliary information in sample surveys

This paper addresses the problem of estimating the population variance S²_y of the study variable y using auxiliary information in sample surveys. We have suggested a class of estimators of the population variance S²_y of the study variable y when the population variance S²_x of the auxiliary variable x is known. Asymptotic expressions of bias and mean squared error (MSE) of the proposed class of estimators have been obtained. Asymptotic optimum estimators in the proposed class of estimators have also been identified along with its MSE formula. A comparison has been provided. We have further provided the double sampling version of the proposed class of estimators. The properties of the double sampling version have been provided under large sample approximation. In addition, we support the present study with aid of a numerical illustration.     

保荐人制度对企业上市的影响研究——基于创业板视角

本文以2009年10月30日至2010年6月30日在创业板上市的90家上市公司为研究样本,对比了上市公司在上市前与上市后的经营业绩,由此指出在创业板开市一年多以来,上市公司未能像市场预期那样实现持续的高增长,与保荐人制度存在的问题密切相关,并根据分析出的问题提出了相应的完善创业板保荐人制度的措施。
