This stage marked by facts and characteristics based on search for information, explore the students world, and their expectations for that science. This study is the first in its kind in United Arab Emirates that try to shed light on the social and psychological effects of the lnternet, therefore we pave the way in front of those who administer lnternet and indicate to them guidelines for that to allow decisions maker to be aware about the world around university＇s student, the world that enjoy less interest for use of Internet at university, and what is the social and psychological effects of the use of Internet. And the study allow providing information and data that several sectors in society need. It draws clear image for the use of Internet at university by the student and whatever social and psychological effects that happened as a result of that use, so it consider as a survey for whom desire to know such information in United Arab Emirates.展开更多

Those who relate to patients with hearing loss (PHL) also share some part of the negative effects. Some specifics are communication disability, which impacts speech and language development, academic performance, and social or work life. In previous years, the problem was predicted to be aggravated as the expected life span of the population increased. The study was conducted among PHL and their family members in JUTH and Kazahyet Audiology Service in Jos. 150 PHL were purposively sampled. The study was guided by a Cross-sectional Survey Research Design, and the specific objectives were to (1) identify the social effects of hearing loss on the PHL, (2) determine the implication of social effects on PHL, and (3) determine the extent at which these social effects affect PHL. The outcome of the study shows that the social effects faced by PHL are poor relationships, no secrets, dependence on sign language, frustration, depression, and dependence on lip reading. Some stop schooling, and others feel laughed at and therefore choose the path of isolation. The implication is that hearing loss is expensive to manage. PHL always feel they are not contributing their quarter in life as usual;they feel stigmatized and are not easy to relate with. The study recommends that the government should come up with policies that will check man-made behaviors that exert negative social effects on PHL in our society, subsidize the cost of hearing aids and cochlear implants to be affordable for PHL, formulate a policy on mandatory newborn hearing screening before the infant is discharged from the hospital to help in the early identification of hearing loss. Finally, the early creation of awareness of the dangers or consequences of hearing loss will go a long way in preventing our society from involvement in high-risk behaviors that will cause hearing loss.展开更多

Also it makes various analyses and evaluation quantitatively and qualitatively on the social and spatial effect of information technology. The results show that the new technology is changing the social spatial behaviors of urban residents. New behavioral spaces of urban family such as telecommuting, email and QQ have begun to emerge. With the help of Internet, the communication scope of families has expanded greatly, and more new forms of publicizing community information have begun to emerge. Telecommunication contact forms have been developing swiftly, and their frequencies of contact have been increasing dramatically.展开更多

The urban environmental pollution causes economic losses,and also brings out negative effects on urban society. Based on the social investigation method,this paper aims to study the harms to urban society brought by environmental pollution. After the investigation to the inhabitants of six typical valley-cities:Lanzhou,Xining,Chongqing,Baiyin,Luzhou and Zigong,we found that the urban environmental pollution has resulted in negative influences with different levels on residents' physical,psychological,work,recreations,studies and social activities. The problem of environmental pollution has become a serious restriction to sustainable development of cities mentioned above. Herewith,it has become urgent to strengthen the government regulations for controlling urban environmental pollution.展开更多

The interview was meant in part to celebrate the tenth anniversary of the implementation of the Labor Law of the People's Republic of China that falls on January 1,2005. We are publishing this transcript with a view to providing our readers with information about how China has worked persistently to protect citizens' right to work and social security and the achievements it has made in this regard. We need to remind our readers of the fact that back in March 2004, the National People's Congress, China's highest legislature, approved a recommendation for revision of China's Constitution. In accordance with the recommendation, the Constitution had one more clause added: The state shall establish and improve a social security system commensurate to the level of the economic and social development.展开更多

The dual economic structure of modern industry and traditional agriculture existing simultaneously is the typical economic structure for most developing countries. How can we break the dual economic structure? After China has carried out the peasant family output-related system of contracted responsibilities, the rural enterprises which develop swiftly and violently are setting up a bridge between traditional agriculture and modern industry. This paper models the triple economic structure formed by traditional agriculture, rural enterprises and modern industry. From the study of structure evolution, we obtain the important relationship between economic growth rate, the rate of technological progress, the growth rate of capital and the growth rate of population, deduce three critical points of population growth, and find out the conditions under which the national economic system forms a stable and orderly self-organized structure. On the basis of quantitative analysis, we propose an approach to the strategies of industrialization of China, especially to the problem of rural enterprise development and rural labor transfer, and give three conclusions and four developmental strategies about national economic system.展开更多

The experimental results show a significant optical signal noise ratio （OSNR） tolerance improvement for PM-2SC- QPSK and PM-4SC-QPSK over PM-QPSK in both back-to-back and 500 km transmission scenarios at the expense of spectral efficiency reduction. This flexible modulation method can be used ＇in elastic optical networks to provide a trade-off between the spectral efficiency and OSNR tolerance.展开更多

However, because users only check-in interaction is highly sparse, which creates a big challenge for POI recommendation. To tackle this challenge, we propose a joint probabilistic generative model called geographical temporal social content popularity（GTSCP） to imitate user check-in activities in a process of decision making, which effectively integrates the geographical influence, temporal effect, social correlation, content information and popularity impact factors to overcome the data sparsity, especially for out-of-town users. Our proposed the GTSCP supports two recommendation scenarios in a joint model, i.e., home-town recommendation and out-of-town recommendation. Experimental results show that GTSCP achieves significantly superior recommendation quality compared to other state-of-the-art POI recommendation techniques.展开更多

文摘With the rapid development of location-based networks, point-of-interest（POI） recommendation has become an important means to help people discover interesting and attractive locations, especially when users travel out of town. However, because users only check-in interaction is highly sparse, which creates a big challenge for POI recommendation. To tackle this challenge, we propose a joint probabilistic generative model called geographical temporal social content popularity（GTSCP） to imitate user check-in activities in a process of decision making, which effectively integrates the geographical influence, temporal effect, social correlation, content information and popularity impact factors to overcome the data sparsity, especially for out-of-town users. Our proposed the GTSCP supports two recommendation scenarios in a joint model, i.e., home-town recommendation and out-of-town recommendation. Experimental results show that GTSCP achieves significantly superior recommendation quality compared to other state-of-the-art POI recommendation techniques.
