新的奋斗，新的丰收

“奋斗是万物之父”，奋斗乃丰收之钥。创造“三农”发展的黄金十年、实现“十连增”“十连快”奇迹，靠的是奋斗；开启“三衣”发展的钻石时代、夺取新的丰收，仍然要靠奋小实现农业强、农村美、农民富，还要靠奋斗。奋斗，将激发亿万农民奔向民族复兴中国梦的巨大豪情；奋斗，将把一个富强民主文明和谐生态的新农村展现在世人面前。     

征服自然和驾驭市场的荒诞

进入21世纪，征服自然的豪言壮语越来越少听到了，几十年前，那可是最流行的口号：“人类认识自然的目的是为了改造自然”，“喝令高山低头，河水让路”。最能体现人类自我意志崇拜的，莫过于“与天奋斗，其乐无穷；与地奋斗，其乐无穷；与人奋斗，其乐无穷”。     

他们在降低抱负！——如何破解隐忧

相对于“步步高升”的箴言，他们更感兴趣的是“稳定”。他们仍然雄心勃勃，也仍在奋斗。但是他们现在为之奋斗的东西却与过去截然不同。     

有一种社会心态叫“焦虑”

时下．一种焦虑的情绪在我们周边蔓延。 “我爸是李刚”成了“官二代”牛气、跋扈的标签，“我奋斗了18年还是不能与你一起喝咖啡”、“蚁族”让人想到“贫二代”的奋斗艰辛。     

不断删除“必须”

1999年有个女记者写我的那篇文章写得非常好，但是题目不好叫做“不知道为什么而奋斗”我当时道为什么而奋斗——我为了追求公平而奋斗。

用“三个代表”重要思想指导审计工作

江总书记“七一”重要讲话高屋建瓴，高瞻远瞩，博大精深，深刻地总结了我党八十年的奋斗业绩和基本经验，揭示了“三个代表”重要思想的科学内涵和精神实质，明确提出了按照“三个代表”的要求，加强和促进党的建设，为实现党的基本路线和历史任务而奋斗的目标。通过认真学习江总书记的“七一”重要讲话，我们深刻体会到，“三个代表”重要思想是我们的立党之本、执政之基、力量之源，是我们各项工作的指导思想和行动纲领。审计是党和国家利益的代表，审计机关代表国家行使审计监督权，是代表广大人民根本利益，维护广大人民根本利益的一个…     

中国大气污染防治需要新思维

大气污染（雾霍污染）．表面上看是体制缺陷问题、资金不足、监管不力、管理不善等问题，实际上是思维缺陷、认识片面性的问题。目前，学术界专业分割与政府部门条块分割叠加，使“同呼吸、共奋斗”的思维难以形成和普及。缺乏“同呼吸、共奋斗”的思维是中国大气污染防治效果不佳的症结和深层原因，具体表现在五大缺陷：

服装业是温州的支柱产业之一。温州“中国鞋都”尘埃落定后，继续叫响“穿在温州”，打造温州“服装名城”和“华服生产基地”已成为700万温州人为之奋斗的目标。各大企业不断亮出自己的法宝利器。     

Gomulka on the soft budget constraint: A reply

Conclusion The preceding two sections of this note cover the main points at issue. There are some other, lesser matters, but these need not detain us here. To repeat: I have found Dr Gomulka's comments constructive and stimulating. They will, I am sure, be helpful both in my future research and in future expositions of my ideas.     

Rejoinders to the comments on my paper “Performance measurement and joint production of intended and unintended outputs”

I will comment on the comments by the groups of three reviewers separately. First of all, I will thank all three groups providing a first round of reports in order for me to get rid of obvious mistakes. In the second round the reviewers were free to comment on the qualities of my revised version. I am not to change my revised paper when giving my comments on what would be honest reports on the quality of my final version. However, the reviewers will not have a go at my rejoinders to comments according to the symposium rules. I keep the section numbering of the authors in order to make it easier to identify the arguments.

     

浅析班级管理“以教育为根本,以学生为主体”的内涵

有人说一个好的班主任应该像母亲一样细心爱护每一个学生;应该像父亲一样严格要求学生;应该像知心朋友一样热心帮助学生。我认为这种说法十分贴切,我决心要当学生们的慈母、严父和挚友。我已经不是第一次当班主任,有一定的经验了。本文根据我做班主任工作的经验探讨了班主任工作理念。     

Discussion

I thoroughly enjoyed reading the article by Bhadra et. al. (2020) and convey my congratulations to the authors for providing a comprehensive and coherent review of horseshoe-based regularization approaches for machine learning models. I am thankful to the editors for providing this opportunity to write a discussion on this useful article, which I expect will turn out to be a good guide in the future for statisticians and practitioners alike. It is quite amazing to see the rapid progress and the magnitude of work advancing the horseshoe regularization approach since the seminal paper by Carvalho et al. (2010). The current review article is a testimony for this. While I have been primarily working with continuous spike and slab priors for high-dimensional Bayesian modeling, I have been following the literature on horseshoe regularization with a keen interest. For my comments on this article, I will focus on some comparisons between these two approaches particularly in terms of model building and methodology and some computational considerations. I would like to first provide some comments on performing valid inference based on the horsheshoe prior framework.

A free-rider problem with a free-riding principal

In a moral hazard problem caused purely by joint production and not by uncertainty, we examine the problem faced by a principal who actively participates in production along with a group of agents. We show that, when designing the optimal output sharing rule, the principal need not look for anything more complicated than the frequently observed simple linear or piecewise linear rules. We also confirm the presence of a friction between the principal’s residual claimant role and her incentive to free-ride in the production process that prohibits her from completely mitigating the moral hazard problem. This paper is from the first chapter of my Ph.D. dissertation at The University of British Columbia, Canada, 1993. I would like to thank my thesis supervisor John Weymark for his many helpful comments and suggestions. I have also benefitted from the comments of Charles Blackorby, David Donaldson, Mukesh Eswaran, Kenneth Hendricks, Ashok Kotwal and Guofu Tan. An anonymous referee and an associate editor provided helpful suggestion. I am also grateful for the hospitality of the Indian Statistical Institute, Delhi Centre, and the Centre for Development Economics, Delhi School of Economics, where parts of the paper were revised while I was a visitor. I am solely responsible for any remaining errors and omissions.     

Equilibrium allocations of endowment-pretension games in public good economies

In a public good economy where agents' preferences are known but endowments are private information, instituting an allocation rule and asking the agents their initial endowments induces an endowment-pretension game. We analyse the Nash equilibrium allocations of this game and discuss its welfare properties with reference to voluntary contributions allocations. Received: 30 May 2001, Accepted: 23 September 2005 JEL Classification: H41 I am grateful to Murat Sertel for his continuous support and encouragement; to G?ksel Asan and Arunava Sen for their invaluable help. I would also like to thank Fikret Adaman, Ahmet Alkan, Salvador Barberá, Semih Koray, Andrei Ratiu, Muhamet Yíldíz, ünal Zenginobuz, an Associate Editor and two referees of the Review of Economic Design for their enlightening comments on previous drafts. Earlier versions of this paper were written during my stay at Universitat Autónoma de Barcelona and at the Indian Statistical Institute. Both visits have been possible by the kindness of the host institutions and the financial support of the Turkish Academy of Sciences and Serem Ltd. It is a pleasure for me to express my gratitude to all these institutions. Of course, all possible errors are mine.     

Uncertainty, the structure of production and the pattern of trade of centrally planned economies

Conclusions In this paper we have demonstrated that terms of trade uncertainty imposes a welfare loss on a centrally planned economy by reallocating resources toward the production of import substitutes and domestic consumption of exportables and a consequent decrease in the volume of trade. We have also shown that the centrally planned economies have developed a number of institutions, such as trade agreements and pricing rules, designed to minimize the losses caused by terms of trade uncertainty. Finally, we have suggested that the behavior of these economies during the post-Warperiod is consistent with welfare maximization under terms of trade uncertainty.I am indebted to Edward A. Hewett and Paul N. Rappoport for their assistance and comments at various stages of my work on this paper. Any errors and all opinions are entirely my responsibility.     

Commentary on workfare: Servitude or success formula?

In his article entitled “Workfare: Servitude or Success Formula?” Patrick J. Keleher Jr. discusses Project Chance, an Illinois public aid program under which refusal of an aid recipient to participate in job training and work internships can result in termination of public assistance. Despite that seemingly coercive aspect of Project Chance, Keleher defends the program as consistent with the basic moral rights of welfare recipients. In my commentary I present reasons why I am not convinced by Keleher's defense of Project Chance.     

多功能发动机汽缸盖检测台的设计制作

康明斯发动机汽缸盖冷却水室和进、排气门密封性检测一直是一个急需解决的难题,由于汽缸盖密封性无检测装置,经常导至发动机拉缸、烧瓦等质量事故,严重的可使曲轴、发动机缸体报废,造成巨大经济损失,为此,自行设计制作了一台多功能汽缸盖密封性检测台,该检测台检测准确度高、工作可靠、方便,自2006年2月份投入使用至今,已检测出不合格汽缸盖65个,在避免重大经济损失的同时,使发动机的维修质量得到了进一步的提高。
