Reconsidering Ideological Lines: Beliefs about Poverty in America*

Our nation's policy to reduce poverty reflects the belief that poverty is caused by institutional discrimination. This study first identifies the ideological and political nature of this position in relation to the classically ideological individualistic and structural beliefs about poverty. Second, it tests a block variable regression model of popular support for the various belief sets to determine how deeply Americans divide along traditional ideological lines. This model includes not only objective status and demographic factors but subjective variables as well. The results indicate only shallow cleavages in beliefs about poverty and account for why previous studies found deeper ones. Support for the institutional discrimination position is especially broad and is independent of support for individualistic or structural beliefs. These findings suggest that this position and its policy represent a successful political compromise and a viable way for people to resolve their ideological inconsistencies.     

Use of pornography in traditional media and on the Internet in Norway

The purpose of this study was to describe the use of pornography in Norway. How many people have used pornographic magazines and films, or watched pornography on the Internet? To what extent do those who watch pornography on the Internet also use it as an arena for erotic chatting? The data stem from a survey on sexual behavior among a random sample of 10,000 Norwegians between the age of 18 and 49. The response rate was 34%. A total of 82% reported to have read pornographic magazines, while 84% had seen pornographic films, and 34% had examined pornography on the Internet. Statistically, there were significantly more men than women who reported use of pornography. There was a 20% difference between men and women in the use of magazines and films. Among those exposed to pornography on the Internet during the past year, 14% had participated in erotic chatting on the Internet. Gay/bisexual men and lesbian/bisexual women reported higher use of pornography than straight men and women. Gender was the most significant variable for the prediction of pornography use. Level of education predicted exposure to pornography on the Internet, in magazines and in films. Younger individuals were more likely to utilize the Internet both for viewing pornographic material and to chat.     

Physical and postural aspects of teachers during work activity

Studies indicate that teachers constitute a professional segment, in which the work characteristics and the demands originating from the act of teaching, favor the emergence of sickness, concerning physical or emotional aspects. The present work aimed to describe physical and postural aspects during the working activity of teachers. A total of 120 elementary school teachers (1st to 8th grade) took part in the survey. For data collection, a questionnaire was applied: it included personal and occupational information, perception of discomfort and being off work; physical strength activities; posture at work and physical conditioning activities. The average age of teachers of the present sample corresponds to 35,8 years. In relation to activities which generate more physical strength, the answer none of the activities was predominant with 30 answers; followed by writing on the board, standing up during the period of classes, explanation of the subjects, class elaboration, correction of homework and others. The area of the body with higher amount of occurrences and prevalent discomfort referred to the lower limbs and spinal cord. These data inform the necessity of investing in prevention programs for the teachers, in order to develop strategies into the organizational context and interventions at the work environment.     

Effects of Impact-Absorbing Flooring in Residential Care from the Perspectives of Enrolled Nurses

Falls are a daily occurrence in nursing homes and few interventions for reducing fall-related injuries have proven to be effective. Impact absorbing flooring (IAF) in residential care has shown promising results in reducing fall-injuries and in the process of developing and implementing IAF all aspects are valuable to explore. Therefore, the aim of this qualitative study is to describe the enrolled nurses (ENs) experiences of IAF. We carried out focus group interviews with ENs and used content analysis to process the data. The ENs experienced both negative and positive aspects with the IAF. Importantly, the ENs perceived the IAF as effective in preventing fall-injuries. They also appreciated the improvements in acoustics. Negative aspects were that the flooring initially was challenging to walk on and that it made it harder to maneuver heavy equipment. A significant and transferable finding in this study was the importance of the ENs' perceived difficulty in preventing fall-injuries amongst elderly people living in nursing homes. This seemed to be a driving force to accept the intervention. Although IAF affects the working conditions in a nursing home, ENs are willing to accept these issues given the perceived effectiveness of the intervention.     

Ergonomics and design: its principles applied in the industry

Industrial Design encompasses both product development and optimization of production process. In this sense, Ergonomics plays a fundamental role, because its principles, methods and techniques can help operators to carry out their tasks most successfully. A case study carried out in an industry shows that the interaction among Design, Production Engineering and Materials Engineering departments may improve some aspects concerned security, comfort, efficiency and performance. In this process, Ergonomics had shown to be of essential importance to strategic decision making to the improvement of production section.     

建设项目的费用控制以及项目费用管理系统的需求

对于许多项目而言,费用严重超支、交付成果低劣的现象更凸显了需要对项目管理流程进行有效的管理和控制。本文叙述了项目从概念设计阶段到完工整个生命周期的有效费用控制,并介绍了进行这种控制所需要的项目费用管理系统在大型建设项目上的应用。     

A demand classification scheme for spare part inventory model subject to stochastic demand and lead time

In this study, we aim to develop a demand classification methodology for classifying and controlling inventory spare parts subject to stochastic demand and lead time. Using real data, the developed models were tested and their performances were evaluated and compared. The results show that the Laplace model provided superior performance in terms of service level, fill rate (FR) and inventory cost. Compared with the current system based on normal distribution, the proposed Laplace model yielded significant savings and good results in terms of the service level and the FR. The Laplace and Gamma optimisation models resulted in savings of 82 and 81%, respectively.     

Telecommunication steering committees and their implications

Rapid advances in telecommunications technology (TT) and its usage have elevated it to a strategic role. This strategic thrust of TT has obvious implications for TT management. This paper reports on a study conducted to identify and analyze the impact of using a distinct steering committee to manage telecommunication technology. Based on statistical analysis of the responses to a survey instrument it is found that having a separate steering committee to manage telecommunication technology has a positive impact on various factors affecting telecommunications usage and management. Implications of our findings for successful TT management are discussed.
