Neogamy and older persons

This paper represents an initial attempt to bring together the literature on neogamy among older persons and to provide a conceptual framework for its understanding. To do so, converging demographic and social factors regarding older persons as they relate to the need for and the expression of intimate relationships are explored. Next the existence and implications of new forms of intimacy among older persons are examined. Finally, some attention is given to the impact of these issues with regard to research, counseling, and public policy.     

Household expenditure patterns and resource pooling: evidence of changes in post-apartheid South Africa

The primary aim of this paper is to examine whether resources accruing to different members of the household and from different sources have differential impacts on household expenditure patterns. The issue is of considerable policy interest for, if the identity of the income recipient does matter in the household’s expenditure decisions, then it indicates the usefulness of targeting income assistance at particular members of the household. The South African evidence is generally supportive of the hypothesis of resource pooling by the income earners in their spending decisions on food, clothing and energy. The results of this paper have been placed in the wider context of social, political and economic developments following the end of apartheid that have caused significant changes in the nature of resource inflow and in the balance of power in decision making within the South African household. The results are indicative of improvements in the standard of living of the majority of South Africans following the end of apartheid.

国家、民族、社区——美国国家公园建设的经验及教训

美国国家公园建设过程中,以国家为主导,注重国家意识,定位服务功能,体现其教育理念,并在此过程中将管理和利用模式由开始的保护转变为现在的保护与利用并行,为全世界提供了一个成功的模板。但在其100年的发展过程中,环境的破坏,原住民权利的漠视,游客管理的混乱,是其曾遇到或正在面临的问题。建议我国在进行国家公园建设时,应扬长避短,突出国家名义,强调社区参与和游客管理先行,并注重国家公园的公益性和教育功能。     

Development and planning of infrastructure

This paper offers a survey of the wide field in infrastructure, a bird's eye view of some of the major problems arising, and some controversial remarks. The aim is to point to the very great importance of the planning and development of infrastructure which decide now how against the background of continued scientific and technological development the environment should be kept or brought under some sort of intelligent control so that the quality of living is steadily enhanced.     

Modelling process robustness: a case study of centrifugal casting

A robust process minimises the effect of the noise factors on the performance of a product or process. The variation of the performance of a robust process can be measured through modelling and analysis of process robustness. In this paper, a comprehensive methodology for modelling and analysis of process robustness is developed considering a number of relevant tools and techniques such as multivariate regression, control charting and simulation within the broad framework of Taguchi method. The methodology as developed considers, in specific terms, process modelling using historical data pertaining to responses, inputs variables and parameters as well as simulated noise variables data, identification of the model responses at each experimental setting of the controllable variables, estimation of multivariate process capability indices and control of their variability using control charting for determining optimal settings of the process variables using design of experiment-based Taguchi Method. The methodology is applied to a centrifugal casting process that produces worm-wheels for steam power plants in view of its critical importance of maintaining consistent performance in various under controllable situations (input conditions). The results show that the process settings as determined ensure minimum in-control variability with maximum performance of the centrifugal casting process, indicating improved level of robustness.     

Ethical encounters: Spivak,Alexander and Kincaid

This essay seeks to engage with the idea of the possibility of meaningful ethical encounters with another. It does not attempt to engage with the broader discourse of ethics. Its purpose is simply to read a few of Gayatri Spivak’s discussions about ethics and alterity and offer a reading of three postcolonial texts in the context of that reading.
