不同时代大事件中大学生爱国行为比较

本文选择1919年五·四运动与2008年三大事件为时间切入点,研究发现五·四时期的大学生爱国行为具有政治性、组织性、宣传动员性、扩散性和妥协性五大特点;而新世纪的新一代大学生在大事件发生时的爱国行为具有主要体现出多元化和理性化的趋势,而五四运动中的五大特点在今日都有不同程度的减弱。这一变化之发生,主要原因在于信息和教育的普及化、大学生群体同质性的下降、时代赋予大学生的使命的变化。文章认为,在竞争愈益激烈的当今社会中,大学生在爱国方面的激情依然没有减退,只是在以不同于以往的形式加以表达。对此要有客观的了解,在此基础上再加以适当引导,以促进大学生群体更好地为构建和谐社会添砖加瓦。     

Generalized empirical likelihood inference in partially linear model for longitudinal data with missing response variables and error-prone covariates

In this article, we consider statistical inference for longitudinal partial linear models when the response variable is sometimes missing with missingness probability depending on the covariate that is measured with error. A generalized empirical likelihood (GEL) method is proposed by combining correction attenuation and quadratic inference functions. The method that takes into consideration the correlation within groups is used to estimate the regression coefficients. Furthermore, residual-adjusted empirical likelihood (EL) is employed for estimating the baseline function so that undersmoothing is avoided. The empirical log-likelihood ratios are proven to be asymptotically Chi-squared, and the corresponding confidence regions for the parameters of interest are then constructed. Compared with methods based on NAs, the GEL does not require consistent estimators for the asymptotic variance and bias. The numerical study is conducted to compare the performance of the EL and the normal approximation-based method, and a real example is analysed.

民事检察监督若干问题的思考

我国现行民事检察监督权运作中存在的缺陷主要表现为按照审判监督程序提出抗诉的方式进行事后监督。因此。检察院即使发现了在审判乏前的民事行为和审判活动存在错误也无法及时进行监督，从而使这种监督形同虚设。为使检察机关具有广泛的法律监督权，真正发挥其监督作用，必须在检察机关提起民事诉讼的范围、方式以及检察机关在民事诉讼中的法律地位、诉讼权利义务等方面，对检察监督制度做出具体设置。

Reliable Ad Hoc Routing Based on Mobility Prediction

Reliability is a very important issue in Mobile Ad hoc NETworks (MANETs). Shortest paths are usually used to route packets in MANETs. However, a shortest path may fail quickly, because some of the wireless links along a shortest path may be broken shortly after the path is established due to mobility of mobile nodes. Rediscovering routes may result in substantial data loss and message exchange overhead. In this paper, we study reliable ad hoc routing in the urban environment. Specifically, we formulate and study two optimization problems. In the minimum Cost Duration-bounded Path (CDP) routing problem, we seek a minimum cost source to destination path with duration no less than a given threshold. In the maximum Duration Cost-bounded Path (DCP) routing problem, we seek a maximum duration source to destination path with cost no greater than a given threshold. We use a waypoint graph to model the working area of a MANET and present an offline algorithm to compute a duration prediction table for the given waypoint graph. An entry in the duration prediction table contains the guaranteed worst-case duration of the corresponding wireless link. We then present an efficient algorithm which computes a minimum cost duration-bounded path, using the information provided in the duration prediction table. We also present a heuristic algorithm for the DCP routing problem. In addition, we show that the proposed prediction and routing schemes can be easily applied for designing reliable ad hoc routing protocols. Simulation results show that our mobility prediction based routing algorithms lead to higher network throughput and longer average path duration, compared with the shortest path routing.

Operational Risk in Financial Services: A Review and New Research Opportunities

We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused mainly on the conceptual and statistical aspects of operational risk management and not on its operational aspects. Operational risk in financial services has not received much attention from the operations management community. The framework presented here is based on the premise that operational risk in financial services can reap significant benefits from research done in the theory and practice of operations management in manufacturing industries as well as in other services industries. The objective of this study is to propose particular challenges and questions raised in the practice of operational risk management that may stimulate future research in this particular area of operations management.
