Java中的指针与引用初探

1995年5月,当Sun公司对外正式发布Java语言的时候,很多人们似乎对这个由Oak发展起来的程序设计语言还不以为然。时至今日,Java已经走过了它辉煌的十几年,在这十几年来,Java风靡全球,跃居程序设计语言榜首。二十一世纪初期,Java这个面向对象的设计语言来到我国,同样也受到了众多程序员的追捧。在这些程序员研究和探索的同时,很多问题也接踵而至。本文从对象谈起,就Java语言中的指针和引用进行了简单的介绍,并进一步阐述了Java中受限指针的存在。

王胡子看盘——黄金趋势线的运用

在股市技术中K线和趋势是股票市场中的基础语言，更是重要的看盘技巧。对于均线一般使用者都是按照电脑软件中的5、10、20、30、60天线，但我喜欢使用黄金趋势线来盘研，实战效果更好。黄金趋势线源于组成黄金分割的系列数字1，2，3，5，8，13，21……，头两位数字相加得出后面的数字，相邻两个数字相比得出我们知道黄金分割0．382：0．618，该黄金分割数字在其他各个领域都有运用，目前在资本股票市场也越来越得到大家的共识，如乔尔·帝纳波利正是运用黄金趋势系列数字来计算逻辑盈利目标点。

The effect of primed goals on employee performance: Implications for human resource management

Overwhelming evidence in the behavioral sciences shows that consciously set goals can increase an employee's performance. Thus, HR professionals have had little, if any, reason to be interested in subconscious processes. In the past decade, however, laboratory experiments by social psychologists have shown that goals can be primed. That is, people's behavior is affected by goals of which they are unaware. Because a conscious goal consumes cognitive resources, this finding has important implications for employee efficiency in the workplace. This paper discusses the results of priming a performance goal in two organizational settings. Call center employees who were primed using a photograph of a woman winning a race raised significantly more money from donors than those who were randomly assigned to a control group. A meta‐analysis revealed that a photograph can prime the subconscious to increase job performance. The results of the present study demonstrate that subconscious motivation is a concept worthy of exploration for both human resource scholars and practitioners. © 2011 Wiley Periodicals, Inc.

The lattice structure of nonlinear congruential pseudorandom numbers

Several known deficiencies of the classical linear congruential method for generating uniform pseudorandom numbers led to the development of nonlinear congruential pseudorandom number generators. In the present paper a general class of nonlinear congruential methods with prime power modulus is considered. It is proved that these generators show certain undesirable linear structures, too, which stem from the composite nature of the modulus.     

Polynomial spline estimation for generalized varying coefficient partially linear models with a diverging number of components

Generalized varying coefficient partially linear models are a flexible class of semiparametric models that deal with data with different types of responses. In this paper, we focus on polynomial spline estimator as a computationally easier alternative to the more commonly used local polynomial regression approach, since one can directly take advantage of many existing implementations for generalized linear models. Furthermore, motivated by the high dimensionality characteristics that accompany many modern data sets nowadays, we investigate its asymptotic properties when both the number of nonparametric and the number of parametric components grows with, but is still smaller than, the sample size. Simulations and a real data example are used to illustrate our proposal.     

Implementing efficient, anonymous and neutral social choice functions

Implementing a social choice function is to endow the agents involved in a collective decision problem with a privately owned decision power, in such a way that by exercising (noncooperatively) this power the agents eventually select the very outcome recommended by the social choice function.In this paper, we show that the concept of dominance-solvable voting scheme allows the implementation of some of the most desirable social choice functions. Namely our main result is the following: If the number of agents n is a prime integer strictly greater than the number of outcomes p then there exists at least one efficient, anonymous and neutral social choice function, in short eanscf, that can be implemented by a dominance-solvable voting scheme. The result is proved constructively, i.e., by looking at a repeated version of voting by veto that is by itself an appealing voting scheme. The arithmetic condition (n should be prime and greater than p) is very natural (since it does not exist an eanscf unless every prime factor of n is greater than p).

模块化与知识员工激励——一个博弈分析

知识员工的激励是企业知识管理的根本问题,但由于知识活动难以监控和测度的特点,传统的激励机制对知识员工而言效果不佳。模块化是广泛应用于欧美制造业的产品设计方法,应用于KM中的主要作用是将大型的复杂的知识体系分解相对简单、小型的独立模块,从而使小型长期的合作团队成为独立的企业基本知识活动单位。这种分解有利于产生一种基于利他合作的知识员工激励机制。本文构建了三个博弈模型:完全信息静态博弈模型、完全信息动态博弈模型和不完全信息动态博弈模型分别解释了没有激励的情况下知识员工的理性选择是不提供知识;小型团体中,只要参与者具有一定的耐心,依靠非正式的规则就可以理性地实现难以移植到大型群体的利他主义合作;长期合作的团队比短期的团队更容易实现合作。     

Global networks of trade and bits

Considerable efforts have been made in recent years to produce detailed topologies of the Internet, but so far these data have been overlooked by economists. In this paper, we suggest that such information could be used to characterize both the size of the digital economy and outsourcing at country level. We analyse the topological structure of the network of trade in digital services (trade in bits) and compare it with the more traditional flow of manufactured goods across countries. To perform meaningful comparisons across networks with different characteristics, we define a stochastic benchmark for the number of connections among each country-pair, based on hypergeometric distribution. Original data are filtered so that we only focus on the strongest, i.e. statistically significant, links. We find that trade in bits displays a sparser and less hierarchical network structure, which is more similar to trade in high-skill manufactured goods than total trade. Moreover, distance plays a more prominent role in shaping the network of international trade in physical goods than trade in digital services.
