Across the literature, the interest in the phenomenon of intolerance of uncertainty (IU) and worry has increased exponentially. However, limited empirical studies exist about the factors that affect IU and worry among older people. The purpose of the study was to examine the impact of spirituality, self-efficacy, and knowledge about aging on IU and worry. A total of 219 Filipino elderly were recruited from institutionalized and hospital care settings. A multiaspect questionnaire was utilized to measure spirituality, self-efficacy, knowledge, intolerance uncertainty, and worry. Exploratory factor analysis (EFA) was used to explore the dimensions of IU and worry. Moreover, structural equation modelling was used to test the hypothesized model. Results of EFA identified four factor dimensions of uncertainty, namely: perfection-driven uncertainty, apprehension-driven uncertainty, avoidance-driven uncertainty, negativism-driven uncertainty. Further, three factor dimensions of worry were also distinguished: constant worriers, obsessive-compulsive worriers, and happy-go-lucky worriers. Moreover, results of structural equation modeling (SEM) showed interaction among the variables presented. Additionally, spirituality showed a positive effect on self-efficacy. However, self-efficacy does not have an effect on IU and worry. Nevertheless, an emerging path between knowledge and IU supported the claim of Nuevo, Wetherell, Montorio, Ruiz, and Cabrera (2009). The study was able to determine the positive effect of spirituality to self-efficacy and its existing correlation with knowledge about aging in relation to elderly's IU and worry. The emerging model can serve as a reference for nurses to address the sociopsychological needs of the geriatric clients employing spirituality and psychiatric nursing.  相似文献

This article considers the nature of RE curriculum policy-making from 1988–97. It concentrates on the hegemonic intent of cultural restorationists. Cultural restorationism finds expression when current political action is justified by particular interpretations being placed upon the past. This involves particular use of language and a strong emphasis on tradition, culture and the past. It is also related to economics, policy-making generally and, for this article, is particularly related to RE curriculum policy-making. The ‘voice’ of the cultural restorationists is explored and the manner in which they proceeded to impact on RE policy-making. The context of text production is explored, with its public ridicule and derision, also the marginalization of key figures and groups with skilful manipulation being made of the media. Language itself was adapted and used as a tool to achieve a manipulative and ‘ratchet-like’ effect on education. Many official documents are used positively to effect their agenda, reflecting hegemonic intent. In religious education policy-making cultural restorationism is aligned closely to a ‘Christianizing’ agenda. This involves the increased use of centralizing powers and the subsequent redefinition of the role for those involved at a local level in RE. Interview data are used from parliamentarians and those seeking to influence the processes. The article concludes that RE is increasingly subject to central control, despite its unique status vis à vis the National Curriculum.  相似文献

Before there was the digital divide there was the analog divide– and universal service was the attempt to close that analogdivide. Universal service is becoming ever more complex in terms ofregulatory design as it becomes the digital divide. In order to evaluatethe promise of the next generation Internet with respect to the digitaldivide this work looks backwards as well as forwards in time. Byevaluating why previous universal service mechanisms failed andsucceeded this work identifies specific characteristics ofcommunications systems – in particular in billing and managinguncertainty – and argues that these characteristics underliesuccess or failure in terms of technological ubiquity. Developing a setof characteristics of services rather than a set of services is afundamental break with the tradition of universal service. In fact, theimplications of our proposal is that basic characteristics in theoffering of the service rather than the absolute price are critical toclose the digital divide: certainty of total charge, ability to avoiddeposits or disconnection via best effort service, and payer-basedcontrol of all charges. While all of these principles sound obvious infact none of these hold in the telephony network. Universal service hasevolved from common carriage (serve all with no discrimination) to aright to basic services (100% penetration). Universal service isnow discussed as the digital divide, as the access to information asopposed to services becomes increasingly critical. However, we arediscussing in this paper access to the bits and the network rather thanaccess to the information (or intellectual property) once connected. Theprovision of universal service is seen as a technical problem only in thatthe technology costs money – universal service debates have longbeen the domain of economists. Yet the design of protocols has been thedomain of engineers, the building of systems the corporate domain, andthe discussion of equity the interest of ethicists. The design ofprotocols can define the parameters of the corporate decision-makers,the variables of the economist, and the questions for the ethicist. Thedesign decisions made at the fundamental levels can make communicationsequity more or less likely. In this work I focus on the design ofprotocols for the next generation Internet, protocols which willfundamentally change the best-effort nature of Internet services.Building on the economic and ethnographic work of others I argue thatthe effects of protocols adoption on universal service can be predictedto some degree. By examination of past and current technologies Iexamine a set of technical mechanisms to determine how such mechanismsmight harm or enhance universal service. I define each mechanism (e.g.denial of entry) and offer observations about each particularmechanism's implicit pricing assumptions. I close with a discussion ofinterest to ethicists and regulators on evaluating communicationsprotocols with respect to universal access. Protocols for developingmultiple qualities of service for packet-switched networks have focusedon economic efficiency (e.g. Mackie-Mason, 1995; Choi, Stahl &Winston, 1997; Shapiro & Varian, 1998), billing to encouragewidespread adoption of network innovations (e.g. Xie & Sirbu, 1985)and billing in a manner consistent with the underlying network (e.g.Clark, 1996). Here we examine a set of protocols which include varyingquality of service mechanisms with respect to the compatibility of theprotocols with universal access.  相似文献

The relation of positive affect to attention and learning was examined in 5-, 7-, and 9-month-olds (N = 84). Affect and attention were assessed while the infants inspected a photograph. Affect was rated globally, for overall mood, and specifically, for amount of time smiling. Attention was indexed by the duration of the infant's longest (or peak) look, a measure previously linked to differential cognitive performance. At all ages, positive affect (shown by approximately half the infants) was associated with long look durations and slower learning, as assessed on a task in which infants learned to distinguish a familiar face from a series of novel faces. By contrast, neutral affect was associated with short looks and faster learning. Affect and look duration had synergistic effects, in that learning was faster than expected for infants who displayed both short looks and neutral affect. These findings are compatible with adult research that links positive affect to less analytical processing, and provide the first evidence that affect may be associated with the speed of processing differences implicated in short and long looking.  相似文献
