招聘的“优平方”——对话亲亲集团人力资源总经理王桂莲

人才不会等待,即使在经济下行的冬天:雇主也不会等待,左手举裁刀,右手摇旗帜,因为招聘的窗口里有梦想的潮汐.特别是“快速招聘”日渐风靡,从求职到受聘平均只需29天.由过去的慢节奏招聘到时下的速招聘,期间的高效能对接离不开“优平方”.当理念优化遇上实务优化,两两相激,犹如两数相乘,是为“长×宽=优平方”.结构化思维是充分考虑事物内在逻辑的方法论.就招聘而言,对多和少、前和后、左和右、大和小、点和面、横和纵等等的把握,使优平方成为可能.

猴年到了,做一个沙和尚吧

年前,一篇帖子开始在网上热传,一名自称是小康家庭出身的上海女孩随相处一年的江西男友回农村过年,在见到男方父母准备的第一顿饭后便提出与男友分手,并以最快速度返回上海.女孩将自己的经历发帖上传到网络,一时间引起网友的热评.事件中的男主角随即发表声明说道:“在哪里跌倒在哪里爬起,既然江西这么穷,表明她还是一块有待开发的处女地,为什么不留下来创业呢?”忽然感觉很讽刺,猴年到了,本是一飞冲天的祥和年,却让这样一则令人心酸的新闻成为春节期间的饭后茶点.

Engaging in duty of care: towards a terrorism preparedness plan

Abstract

A minor digression, if you will: it has been over 30 years since I (referring to lead author) first wrote on the topic of terrorism and its potential impact on conducting business in a global context. The most vivid memory I have relative to that initial foray into this new topic was making a presentation at the annual summer American Marketing Association (AMA) conference in Chicago. I got halfway through the paper and I started to hear jeering noises emanating from the audience. As I remember (it is not a pleasant memory), the audience thought that I had lost my mind and that the reviewers of the paper allowed this rubbish into the AMA meeting (the implication was that they must have been drinking at the time). This is a true account of the presentation and when I left the session, I would be dishonest if I didn’t tell you that I had made a terrible error and there would be significant ramifications to my young academic career. Yet, no country is untouched by global terrorism today, and the ramifications for global organizations are escalating year by year.     

我在彷徨的印尼

十年互联网“剩者”张朝阳迎来事业第二春，他仍有虚荣心，但不再焦虑，正在“把奋斗变成不奋斗”     

On Granger’s predictability of financial markets in theory and practice

I was kindly invited by the organizers to discuss the presentation by Professor Clive Granger at the 5th International Institute of Forecasters Workshop in Lisbon, which was, perhaps, the last one that he ever delivered in a regular meeting. The task would have not been easy in any case, given his deep knowledge of the field and his many contributions. My discussion, however, turned out to be more difficult than I anticipated, given that there was no formal paper to discuss, just some sparse notes that he had written at various different dates, but certainly before the spectacular gyrations that hit the speculative markets in mid to late October 2008 and early December 2008. During our brief encounters at the workshop, he mentioned the thought of expanding his notes and writing a full-length paper on the issue. However, his unexpected demise left this thought unrealized. The editors of this special issue thought that it would remain incomplete without his outstanding contribution, and invited me to write my reflections on his notes and his verbal presentation. If discussing the paper (in an informal setting) was already daring, writing a paper on such a wide and complicated topic was a daunting task. I had many reasons for refusing the assignment; however, in the end, I felt that I should take it, if only as a personal homage to a giant in our discipline.     

Is It Time To Createa New Theoryof the Firm? Discussion

In this comment on James Emshoff's (1993) paper, ¹ I will begin by briefly summarizing the paper. Then I will give my reaction to the issues raised in the paper from the perspective of an economist and professor of business strategy. As I discuss later, it is the work of Alfred Chandler, Jr., rather than work of economists, that is most relevant to the issues raised by Emshoff. In my view economists must understand the limitations of standard economic approaches to organizational issues in order to begin to make progress on issues raised by Chandler and Emshoff.     

De‐Essentializing the Knowledge Intensive Firm: Reflections on Sceptical Research Going against the Mainstream

This paper provides an updated summary and discussion of my 1993 JMS paper ‘Organization as rhetoric: knowledge‐intensive firms and the struggle with rhetoric’, and relate this to my own and others' later work in the area explored in the paper: knowledge‐intensive work and discourse. A key aspect of knowledge work is the ambiguity of what it stands for, what people working with ‘knowledge’ are doing, and what they accomplish. This fuels identity uncertainties, which is also addressed and reflected upon in the paper. As part of my broader reflections, I also provide a brief overview of some methodological ideas on how to do problematization: a key theme in the original piece but which is more generally a research approach that may lead to contributions that generate interest.     

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.     

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。     

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.

     

Dynamic agency with persistent observable shocks

This paper studies a continuous-time hidden-action model with persistent observable shocks. In this model, I develop a method to characterize the optimal contract with history-dependent effort exertion and shirking decisions. Temporal shirking is always optimal after some histories as long as a positive persistent shock is expected. As a result, my model gives rise to a mechanism through which the moral hazard problem amplifies macroeconomic fluctuations. I also show the pattern of the agent’s utility adjustments with respect to persistent shocks and its implications for compensation design.
