This article presents a UK-based research that has studied the existing sheltered or assisted living housing population and its future housing options and preferences. This meets an identified need to know and understand users' needs and requirements in much more detail that outlines what is liked and disliked by older people about sheltered housing, so that those who plan and design such housing can be aware of their views. The study also sought to understand the architects' challenges in designing and adapting this type of housing. The sheltered housing managed by housing associations in Belfast, Northern Ireland, was assessed through a series of site visits, structured interviews, and a focus group with stakeholders. Findings revealed older users' keen interest in participating in their housing needs assessment, identified building design concerns and provided recommendations for potential design guidelines. 相似文献

In a make-to-order environment, lead time and price can play a crucial role in determining the financial success of a firm. Their importance increases when demand is sensitive to the quoted lead time and price. A model is presented which uses the quoted lead time and price as a mechanism to determine the optimal demand level. The relationships between the model parameters and their impacts on the firm's profit is also analysed. In addition, the effect of the number of job requests, and the mean processing time are examined. Based on the results presented in this paper, there is clear indication that the firm's profit is sensitive to the inventory holding rate, and that the inventory holding cost component is redundant in the presence of a tardiness cost component. 相似文献

Le marché du travail du Moyen-Orient et de l'Afrique du Nord se caractérise par un chômage des jeunes généralisé et par un nombre disproportionné de chômeurs parmi les nouveaux diplômés. À partir des enquětes du BIT sur le passage de l'école à la vie active menées en Égypte, Jordanie et Tunisie, les auteurs regardent si cela tient à l'inégalité des chances ou à des caractéristiques structurelles induisant des discordances entre offre et demande de travail. Les principales explications seraient le faible nombre d'emplois qualifiés disponibles et le peu de valeur accordée aux qualifications acquises dans le système de formation professionnelle. 相似文献

This article examines the gradual evolution of the French Régulation school (FR) for the study of capitalism through the lens of structure and agency. The analysis first segments the school into two epochs, the early Régulation, led by authors Aglietta and Lipietz, and the later Régulation, which saw the rise of Boyer. We find that the gradual progression that occurred within the FR school is linked to its authors' implicit ontic engagement with structure and agency, which, in turn, provides natural linkages to Critical Realism. In the second part of the paper, we demonstrate how the comparison between Morphogenetic Régulation and French Régulation (FR) can facilitate a much deeper reading of the structure-agency debate pertaining to the transformation of capitalism. In so doing, it discusses the value addedness of Morphogenetic Régulation through three specific concepts by stressing their relevance for contemporary studies in international political economy. These concepts are: stratified emergence; causality and the problématique of hierarchy. 相似文献

人文外交作为一种崭新的外交形式,是对当今国际关系领域中国家、市场与社会三者互动的有效应对,也是对文化外交和公共外交的有机整合。人文外交以软实力理论、国家形象理论、建构主义理论和文明对话理论为依托,在当今中国的外交政策中占有重要地位。新中国对阿拉伯世界的外交实践则为人文外交的理论创新积累了宝贵经验。在对阿关系中,人文外交在各时期都促进了中国国家利益的拓展。当下,国际体系处于转型期,尤其是2010年年底以来阿拉伯世界所发生的社会和政治动荡,使中国对阿拉伯世界的外交政策面临挑战。只有将人文外交继续作为我国对阿外交政策的重点,才能在政治动荡的阿拉伯世界始终维护中国的国家利益。 相似文献

Manufacturers want to assess the quality andreliability of their products. Specifically, they want to knowthe exact number of failures from the sales transacted duringa particular month. Information available today is sometimesincomplete as many companies analyze their failure data simplycomparing sales for a total month from a particular departmentwith the total number of claims registered for that given month.This information—called marginal count data—is, thus,incomplete as it does not give the exact number of failures ofthe specific products that were sold in a particular month. Inthis paper we discuss nonparametric estimation of the mean numbersof failures for repairable products and the failure probabilitiesfor nonrepairable products. We present a nonhomogeneous Poissonprocess model for repairable products and a multinomial modeland its Poisson approximation for nonrepairable products. A numericalexample is given and a simulation is carried out to evaluatethe proposed methods of estimating failure probabilities undera number of possible situations. 相似文献

ABSTRACTRecent contributions to the study of neoliberalism have made considerable advances in transcending the dichotomy between understandings of the concept either as an ‘ideology’ or as a monolithic ‘structure’. In particular, the Variegated Neoliberalization (VNLT) approach has proposed an understanding of neoliberalism that relies on a path-dependent moment (i.e. the ‘uneven development of neoliberalization’) which is then followed by a path-shaping moment (i.e. the ‘neoliberalization of regulatory uneven development’). Such a perspective allows us to understand both systemic and contingent tendencies in neoliberalization processes across different geographies, transcending the socially constructed North–South divide. However, the VNLT approach has encountered a number of critiques, particularly in relation to its treatment of agency. In order to transcend these critiques and propose a more nuanced understanding of ways agents reflexively and recursively interpret and deepen – or refrain from deepening – neoliberal norms, I turn to the Strategic-Relational Approach (SRA) proposed by [Jessop, B. (2001). Institutional re(turns) and the strategic – relational approach. Environment and Planning A, 33(7), 1213–1235]. Through the SRA, it becomes possible to pinpoint both instances of ‘structured coherence’ and ‘patterned incoherence’ resulting from agential reflexivity in different contexts of neoliberalization. I will therefore turn to cases where these two patterns can be observed in the context of Euro-Mediterranean policies – that is, Morocco’s ‘structured coherence’ due to its internalized and deepening neoliberalization, and Egypt’s ‘patterned incoherence’ as a result of its still uneven development of neoliberalization. 相似文献

Leveraging historical data into the design and analysis of phase 2 randomized controlled trials can improve efficiency of drug development programs. Such approaches can reduce sample size without loss of power. Potential issues arise when the current control arm is inconsistent with historical data, which may lead to biased estimates of treatment efficacy, loss of power, or inflated type 1 error. Consideration as to how to borrow historical information is important, and in particular, adjustment for prognostic factors should be considered. This paper will illustrate two motivating case studies of oncology Bayesian augmented control (BAC) trials. In the first example, a glioblastoma study, an informative prior was used for the control arm hazard rate. Sample size savings were 15% to 20% by using a BAC design. In the second example, a pancreatic cancer study, a hierarchical model borrowing method was used, which enabled the extent of borrowing to be determined by consistency of observed study data with historical studies. Supporting Bayesian analyses also adjusted for prognostic factors. Incorporating historical data via Bayesian trial design can provide sample size savings, reduce study duration, and enable a more scientific approach to development of novel therapies by avoiding excess recruitment to a control arm. Various sensitivity analyses are necessary to interpret results. Current industry efforts for data transparency have meaningful implications for access to patient‐level historical data, which, while not critical, is helpful to adjust for potential imbalances in prognostic factors. 相似文献
