The effect of unconditional preferences on Sen’s paradox

Theory and Decision - Sen’s Liberal paradox describes a conflict between weak Pareto, minimal liberalism, and either transitivity or a best element over a domain of individual preferences....     

Strengthening home and community-based care through Medicaid waivers

States are increasingly using the Medicaid 1915c waiver program to provide community-based long-term care (LTC). We examined state predictors of waiver utilization and expenditures for waivers serving both older and working-age individuals. State level data for the period 1992 to 2001 were used to estimate random effects panel models. States with increased community-based care (e.g., home health agencies) and decreased nursing home bed capacity were positively associated with state per capita rates of use, expenditures, and the share of Medicaid LTC dollars supporting 1915c waivers. States appeared to substitute Medicare for Medicaid services for individuals eligible for both. State per capita income was positively related to each measure. State policies that facilitate decreased institutional and increased community- based capacity appear essential to state efforts to expand access to community-based services. Federal policies that address state resource issues may also spur growth in community-based LTC, which, in most states, continues to be limited.     

An Intranet based system as an enabler in effective project management and implementation of quality standards: A case study

This paper reports on the development of an Intranet based system, as an enabler in project management and implementation of a quality standard (ISO9001:2000) at Tyco Fire & Integrated Solutions Oil Gas & Marine Europe, a subsidiary of Tyco International a worldwide Engineering Conglomerate, (Referred to as TFIS). The system enabled stakeholders to follow standard project protocols, playing an important role in creating integration between different sub-sections. This paper discusses the strategic relevance of the system in achieving desired business outcomes, by making the organisation more responsive, agile and increasing the accountability of stakeholders involved in managing projects.     

A Theoretical Model of Intergenerational Tutoring

ABSTRACT

This paper presents a psychological model of intergenerational tutoring, which applies to both helpers and those who are helped. It shows how fully formed intergenerational tutoring can operate, and can thus identify gaps. These gaps can be addressed and some filled by learning partners, perhaps with help from professionals or more experienced partners. Sixteen elements are identified, the first two in sequence, then five with equal weight, then nine in sequence. The model is a template for monitoring intergenerational interactions as they are happening. It also forms a tool for self-assessment/peer assessment. Additionally, it may help in designing intergenerational tutoring.     

斯图亚特·霍尔著作中的都市生活与城市空间

在霍尔的著作中,城市空间扮演了政治想象及其实践舞台的双重角色。城市是一种自由与隔离相互交织的矛盾领域,重构了人们考察种族、权利和身份等问题的思维方式。都市生活感是将身份进行理论确认的经验认识转化为一种理解权利语言和社区语言之不可通约性的基本特征,而这便是对21世纪的全球化大都市中的种族政治学的一种理解。     

School Belonging,Generational Status,and Socioeconomic Effects on Mexican‐Origin Children's Later Academic Competence and Expectations

This study examined factors that relate to academic competence and expectations from elementary to middle school for 674 fifth‐grade students (50% boys; M_age = 10.86 years) of Mexican origin. Models predicting academic competence and expectations were estimated using a structural equation modeling (SEM) framework, with longitudinal data from fifth to eighth grades. School belonging (i.e., social and emotional connectedness to school) predicted greater academic competence and expectations over time. Findings indicate that student feelings of belonging in school may act as a resource that promotes academic competence and expectations. Furthermore, family income, parent education, and generational status had direct effects on academic competence and expectations to some degree, suggesting the importance of contextual factors in this process.     

Programs to Improve the Social and Emotional Wellbeing of Aboriginal and Torres Strait Islander Communities

Attending to the social and emotional wellbeing of those from Aboriginal and Torres Strait Islander cultural backgrounds is widely recognised to play a key role in effective social work practice. However, relatively little is currently known about what effective practice comprises, and significant challenges exist in any effort to demonstrate that programs do achieve significant change both for individual participants and the communities in which they live. This paper considers one program, Seasons for Healing, to illustrate the type of intervention that holds promise when working with adults and discusses the difficulties that arise in both defining and assessing program outcomes.     

Bias in linear model power and sample size calculation due to estimating noncentrality

Data analysts frequently calculate power and sample size for a planned study using mean and variance estimates from an initial trial. Hence power,or the sample size needed to achieve a fixed power, varies randomly. Such claculations can be very inaccurate in the General Linear Univeriate Model (GLUM). Biased noncentrality estimators and censored power calculations create inaccuracy. Censoring occurs if only certain outcomes of an initial trial lead to a power calculation. For example, a confirmatory study may be planned (and a sample size estimated) only following a significant resulte in the initial trial.

Computing accurate point estimates or confidence bounds of GLUM noncentrality, power, or sample size in the presence of censoring involves truncated noncentral F distributions. We recommed confidence bounds, whether or not censoring occurs. A power analysis of data from humans exposed to carbon monoxide demonstrates the substantial impact on samle size that may occur. The results highlight potential; biases and should aid study planning and interpretation.
