匀变速直线运动的判断

以物体做匀变速直线运动的判断方法，对利用位移差相等（△Ｓ＝ａＴ２）来判断物体是否作匀变速直线运动进行分析，论证了位移差相等只是判断物体作匀变速直线运动的必要条件，给出了该判断的充要条件是，对验证匀变速直线运动的实验提出了采用频率可调打点计时器和对运动物体增系一个速度计等改进意见．

用以健康监控的微型光学传感系统

家庭健康监控是现代医疗的一个新兴领域,其目的主要在于监控老年人的机体功能,改善老年人的日常生活质量。一套完整的健康监控系统可以粗略地包括传感器、信号处理单元和通讯单元等功能模块。由于兼具灵敏和便于微型化的特点,光学传感系统逐渐成为研发的焦点,本文中我们将重点讨论两类光学传感系统:(a)以脉搏血氧计为代表的非侵入式光学传感系统;(b)以微型谐振器为例的用于体液检测的光学传感系统。这两个研究领域的目标都是希望能利用现有的半导体和集成化领域的工程技术来实现微型化、便携式、低成本的传感系统。     

回归生活世界与构建文化哲学——论世纪之交哲学理性的位移和发展趋向

随着发展哲学、交往理论、新儒学、后现代主义、文化哲学、人学、经济哲学、公共哲学、政治哲学、历史哲学、自然哲学、科学技术哲学等具体哲学研究领域的兴起，世纪之交的中国哲学理性正在重新为自己定位世俗化和向生活世界回归。哲学回归生活世界有两种基本方式，一是应用哲学所代表的对生活世界的外在审视或外在规范的方式，一是文化哲学所代表的对生活世界的内在启蒙或内在教化的方式。相比之下，后者更为深刻。中国文化哲学的建构途径是促使对人的形而上的思考同实证的文化批判的统一、人本精神和科学精神的统一、精英文化与市民文化的整合。     

Where does time spent on the Internet come from? Tracing the influence of information and communications technology use on daily activities

We explore from a time-use perspective how private use of computers and the Internet [information and communications technologies (ICTs)] is transforming everyday life. Data from the Swedish 2010–2011 Time-Use Survey reflect a situation in which Internet use has spread widely and become routine for many. Using covariate analysis, we analyse differences in general time use between four groups of ICT users ranging from non-users to heavy users. The theoretical departure point is a nuanced discussion of the time-displacement concept. Results indicate that private time spent using ICTs is associated primarily with individuals’ available free time, that is, elastic relative to time for paid work (i.e. contracted time). Heavy ICT users spend more time on activities carried out alone, are more home centred, and less mobile. Heavy use is associated with somewhat less committed time spent, for example, on maintenance work or taking care of children. Regarding personal time, time for meals is negatively related to heavy use, while night-time sleep is unaffected. Concerning free time, heavy use takes time from sports and outdoor recreation, but has no effect on offline media use, entertainment and cultural activities, or reading. Heavy use does not affect time spent on social activities, for example, for social interaction with family and friends or time spent on voluntary associations. Observed differences become significant at certain thresholds of ICT-related time use, involving heavy users who spend one hour or more on computers and the Internet every day.     

A remote sensing look at the economy of a Russian region (Rostov) adjacent to the Ukrainian crisis

Satellite data used in combination with a stochastic production function method reveal an inefficient formal economy in rural Rostov Oblast 2013–2015 embedded in an overall (formal and informal) relatively efficient economy with the measurement of both important to better understand non-economic impacts of sanctions. Increased military activity may have insulated the formal economy of the border area from poor economic performance and the deindustrialization that characterizes adjacent areas. The current Oblast Administration’s grant program to localities does not reward relatively efficient economic performance with a model suggested here to change the policy. The region’s economy has the ability to absorb many Ukrainian refugees though non-economic issues support the current assistance from other Russian regions in helping relocate refugees beyond Rostov region. Like other conflict zones, urban areas experience less of an impact relative to rural areas.     

Displaced and segregated: The socio-economic status of the second generation of internally displaced Palestinians in Israel

This study investigates the effects of displacement on the socio-economic status of second-generation Palestinian internally displaced persons (IDPs) in Israel. The results show that members of this group do not differ from non-displaced Palestinians in their educational or occupational attainment, but that displaced households experience higher rates of poverty and poorer housing conditions than non-displaced households. I find that the relationship between displacement and the prime indicators of social mobility—education and jobs—was weakened by three factors: extreme spatial segregation between Palestinians and Jews, the concentration of disadvantage among Palestinian IDPs within the host communities, which were Palestinian spaces, and a high level of dependence on resources concentrated in Jewish spaces among all Palestinians, not just IDPs. These three conditions, however, do not eliminate gaps in assets and land ownership between IDPs and non-displaced Palestinians, which, I argue, contribute to higher poverty rates among displaced households.     

人工智能对人力资源的替代影响研究

人工智能在提高社会生产效率和促进经济增长的同时,也带来了技术风险和伦理争议."机器换人"的忧虑成为社会各界乃至个人关注人工智能的焦点.经文献分析,以人工智能为代表的技术进步会通过对劳动力供需结构、组织商业环境、社会分工方式以及劳动者的工作场景和认知结构的影响,进而实现对劳动力、组织、职业、任务和技能的替代和革新.随着智能社会的到来,人工智能与人力资源之间应建立动态适配、融合互补、和谐共生的伙伴关系,实现技术进步与人类利益的共同繁荣.我国是人力资源大国,正处于向创新驱动发展转型的新旧动能转换期,增加就业机会、保护劳动权益、更新职业技能、设置技术伦理底线等政策措施,能够减轻人工智能替代人力资源带来的负效应,消解人工智能对人力资源领域带来的无益冲击.     

On the maximum likelihood estimation of parameters of a spatial discrimination model

Consideration is given here to the problem of maximum likelihood estimation of parameters in a sparial discrimination model which was proposed by switzer (1980). some moments of these estimators are derived. These results extend the work of Mardia (1984) who gave expressions for these estimators without their moments.
