商业软件专利化问题研究

软件版权保护与专利保护存在巨大差异,目前中国并没有实现对软件的实质性保护,只限于版权范畴。美欧日对商业软件专利化研究已经超越是否予以保护的基础性问题,而是潜心于如何最合理认定商业软件专利化的技术认定标准问题,甚至正在启动联合专利直通车的跨国计划。在中国国内技术竞争和美欧日软件专利化大幅革新的推动下,软件专利法议题开始纳入中国专利法修改的考量之列。如果熟悉关欧目的立法现状和认定方法,就会对中国市场上的创意保护及开源软件的相关争议有所释解。可以预见的,中国对商业软件提供实质保护具有重大的创新意义。     

机器人实验教学平台软件的设计与实现

机器人技术已成为国际学术界关注的一项热点问题。开发机器人实验课程,让研究生接触到国际先进的机器人具有重要意义。现有实验用机器人不具备可操作的人机交互接口,造成实验过程中要编写大量的底层代码,浪费了宝贵的时间。针对此问题,设计并实现了一套移动机器人直接控制实验平台软件,提高了课程时间的利用效率,增强了课程的可扩展性。同时将学生的精力集中在控制算法的开发与实现过程,达到了研究生实验课的培养目的。

L-moments of the Birnbaum–Saunders distribution and its extreme value version: estimation,goodness of fit and application to earthquake data

Understanding patterns in the frequency of extreme natural events, such as earthquakes, is important as it helps in the prediction of their future occurrence and hence provides better civil protection. Distributions describing these events are known to be heavy tailed and positive skew making standard distributions unsuitable for modelling the frequency of such events. The Birnbaum–Saunders distribution and its extreme value version have been widely studied and applied due to their attractive properties. We derive L-moment equations for these distributions and propose novel methods for parameter estimation, goodness-of-fit assessment and model selection. A simulation study is conducted to evaluate the performance of the L-moment estimators, which is compared to that of the maximum likelihood estimators, demonstrating the superiority of the proposed methods. To illustrate these methods in a practical application, a data analysis of real-world earthquake magnitudes, obtained from the global centroid moment tensor catalogue during 1962–2015, is carried out. This application identifies the extreme value Birnbaum–Saunders distribution as a better model than classic extreme value distributions for describing seismic events.     

知识转移绩效影响因素的实证研究——以软件行业为例

在总结国内外已有相关文献的基础上,结合"物理-事理-人理(W-S-R)"系统方法论,对以往学者提出的知识转移的阻碍因素和解决方法进行了归纳,提出并建立了针对组织内部知识转移绩效的影响因素的研究模型.通过向国内软件企业发放问卷的方式对该模型进行了实证研究,在对问卷数据充分分析后,得出了现实中影响我国软件企业知识转移绩效的关键因素和其他一些新颖的结论.     

Measuring open source software success

Since the mid-1990s, there has been a surge of interest among academics and practitioners in open source software (OSS). While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.     

知识经济与软件商品

知识经济时代的到来 ,使凝结在社会财富中的科学技术含量日益增加 ,软件随之成为独立的存在 ,并已走向商品化。软件的无形属性 ,不像硬件那样容易触摸 ,所以常常使人忽视其存在 ,形成若干观念误区。软件的总体数量超过硬件 ,是人类历史的进步 ,标志着社会生产力进入了崭新的阶段。文章对知识经济时代的软件商品做了全面考察。当前的重要任务就是从简单的粗放劳动解放出来 ,走向高效细腻的智力劳动 ,知识经济时代也就是软件商品时代

Estimating the goodman,keyfitz, pullum kinship equations: An alternative procedure∗

As is often the case in demography, Goodman, Keyfitz and Pullum (1974) developed their theory of the interrelationships of fertility, mortality and kinship numbers by means of continuous mathematics [integrals], but resorted to ad hoc finite approximations for calculating results in concrete empirical cases. Their reason: ‘Ordinarily, we cannot evaluate the l(x) and m(x) functions for arbitrary values of x, since the data are usually collected for five‐year age intervals’ [p. 24]. Recent developments in computer software now provide an alternative, two‐step procedure that avoids extensive programming of finite approximation algorithms: 1) using a popular scientific curve‐fitting package, functions are found to represent particular sets of discrete data on fertility and mortality, 2) the resulting functions and parameter estimates are then inserted directly into the kinship equations, and the integrals evaluated numerically using readily available mathematics software. This procedure has potentially wide application in other areas of population mathematics where theory is given by integrals and other continuous expressions, but data are for discrete age groups.     

Gendered work culture in free/libre open source software development

This article adopts a feminist perspective to examine masculine work culture in the development of free/libre open source software. The authors draw on a case study of the ‘Heidi bug’ discovered during the development of the Mozilla Firefox web browser to examine how ‘gendered talk’ was (en)‐acted to facilitate ‘bricolage’ in an online work environment. Such gendered talks contain cultural references familiar to male developers. Though seemingly innocuous, such acts could be seen as a performance of gender that simply reflects the hegemonic heterosexual masculine culture manifested in an online virtual work space. The virtual work space therefore can be exclusive to those who shared the cultural references. Although it may not necessarily be ignorance or insensitivity of male developers, a more gender‐balanced, women‐friendly and inclusive workplace certainly would benefit from a more diverse environment. This article highlights the gendered aspect of software development through examining the language use and mainstream ‘bricolage’ practice, and establishes a compelling ground for enlarging the talent pool to include more women and integrating gender ethics (e.g., raising awareness of sensitive language and design approaches) into computer ethics education.
