Being the “Go-To Guy”: Fatherhood,Masculinity, and the Organization of Work in Silicon Valley

Based upon in-depth interviews with fathers who are employed as knowledge workers in Silicon Valley, this article argues that a newly constituted masculinity has emerged that coincides with the new way work is organized in the new economy. The article examines the relationship among this gendered subjectivity, processes of labor control, and fathering. It finds that the new masculinity functions as a key mechanism of control in high-tech workplaces that rely on identity-based forms of control and that the enactment of this new masculinity impacts the way fathers think about, experience, and manage their work and family lives.     

A marked point process perspective in fitting spatial point process models

This paper discusses a new perspective in fitting spatial point process models. Specifically the spatial point process of interest is treated as a marked point process where at each observed event x$\mathbf{x}$ a stochastic process M(x;t)$M(\mathbf{x};t)$, 0<t<r$0<t<r$, is defined. Each mark process M(x;t)$M(\mathbf{x};t)$ is compared with its expected value, say F(t;θ)$F(t;\theta )$, to produce a discrepancy measure at x$\mathbf{x}$, where θ$\theta$ is a set of unknown parameters. All individual discrepancy measures are combined to define an overall measure which will then be minimized to estimate the unknown parameters. The proposed approach can be easily applied to data with sample size commonly encountered in practice. Simulations and an application to a real data example demonstrate the efficacy of the proposed approach.     

A latent process model for dementia and psychometric tests

We jointly model longitudinal values of a psychometric test and diagnosis of dementia. The model is based on a continuous-time latent process representing cognitive ability. The link between the latent process and the observations is modeled in two phases. Intermediate variables are noisy observations of the latent process; scores of the psychometric test and diagnosis of dementia are obtained by categorizing these intermediate variables. We propose maximum likelihood inference for this model and we propose algorithms for performing this task. We estimated the parameters of such a model using the data of the 5 year follow-up of the PAQUID study. In particular this analysis yielded interesting results about the effect of educational level on both latent cognitive ability and specific performance in the mini mental test examination. The predictive ability of the model is illustrated by predicting diagnosis of dementia at the 8 year follow-up of the PAQUID study based on the information from the first 5 years.     

市场化进程对经济增长的推动作用——典型事实与定性解释

中国的市场化进程对经济增长的推动作用能不能被学习?也就是说,市场化对经济增长的推动作用是否具有一般规律性?世界经济史上两百年、几十年间和当今的典型增长事实表明,市场化进程对经济增长有明显的推动作用.公元2000年的世界各国截面数据也支持这一论断.市场化进程同时通过以下若干效应对经济增长起到推动作用:1.人力资本投资快速增长;2.吸引了增量资本;3.提高了存量资本的配置效率;4.自由贸易直接传播生产技术.     

对税务流程再造的探讨

在我国探讨税务绩效管理必须进行税收业务流程的再造,建立以咨询、受理、核批、调查、评估、检查和执行等七个结点为主的税收业务主流程;在此基础上,改变传统税务管理以职能为导向的组织结构,建立以税务流程为导向的扁平化组织结构,以实现税务组织内部结构机制的改革。     

局部平稳过程、稳定过程及GARCH模型的比较研究

本文在Granger（2005）[1]研究成果的基础上对局部平稳过程的大样本性质进行了深入探讨,发现了一些颇具实际价值的理论结果,弥补了Granger（2005）仅利用预测效果标准得到金融数据生成过程的不足,进一步给出了适合于实证分析的判断金融数据生成过程的标准,并在此基础上详细讨论了局部平稳过程、稳定过程及GARCH模型在大样本情况下的区别。本文运用研究得到的结果,在非平稳框架下对中国股票市场上证180指数进行了分析,发现上证180指数收益率具有明显的非平稳特性,并在此基础上进一步讨论了中国股票市场的市场有效性问题。
