Some asymptotic results in finite populations

In this paper we investigate limiting properties of predictors of some finite population quantities. Both, the sample size and the population size are considered to become large. Limiting properties like consistency and asymptotic normality of the best linear unbiased predictors of the population total and of the finite population regression coefficient are investigated.     

Mean-squared errors of small-area estimators under a unit-level multivariate model

This work deals with estimating the vector of means of certain characteristics of small areas. In this context, a unit level multivariate model with correlated sampling errors is considered. An approximation is obtained for the mean-squared and cross-product errors of the empirical best linear unbiased predictors of the means, when model parameters are estimated either by maximum likelihood (ML) or by restricted ML. This approach has been implemented on a Monte Carlo study using social and labour data from the Spanish Labour Force Survey.     

Augmented mixed beta regression models with skew-normal independent distributions: Bayesian analysis of labor force data

Abstract

Augmented mixed beta regression models are suitable choices for modeling continuous response variables on the closed interval [0, 1]. The random eeceeects in these models are typically assumed to be normally distributed, but this assumption is frequently violated in some applied studies. In this paper, an augmented mixed beta regression model with skew-normal independent distribution for random effects are used. Next, we adopt a Bayesian approach for parameter estimation using the MCMC algorithm. The methods are then evaluated using some intensive simulation studies. Finally, the proposed models have applied to analyze a dataset from an Iranian Labor Force Survey.     

INDEX TO VOLUME 7 (1989)

Surveys of forecasters, containing respondents’ predictions of future values of key macroeconomic variables, receive a lot of attention in the financial press, from investors and from policy makers. They are apparently widely perceived to provide useful information about agents’ expectations. Nonetheless, these survey forecasts suffer from the crucial disadvantage that they are often quite stale, as they are released only infrequently. In this article, we propose MIDAS regression and Kalman filter methods for using asset price data to construct daily forecasts of upcoming survey releases. Our methods also allow us to predict actual outcomes, providing competing forecasts, and allow us to estimate what professional forecasters would predict if they were asked to make a forecast each day, making it possible to measure the effects of events and news announcements on expectations.     

A Mixed Method Approach to Quality of Life Research: A Case Study Approach

Increased use of qualitative and quantitative methods in quality of life projects necessitates an examination of how to effectively work within a mixed method framework. The research objectives of this paper are to (1) operationalize the two goals of mixed method research (confirmation and comprehension) and (2) develop a strategy for using mixed methods in quality of life research. Face-to-face interview (qualitative) and telephone survey (quantitative) data from the Community–University Institute for Social Research Quality of Life (CUISR QoL) project in Saskatoon, Saskatchewan were used for operationalization. Overall, confirmation and comprehension were challenging concepts to operationalize. Seven benefits and four guidelines were developed and are presented as dynamic, rather than definitive, structures.     

淳于髡及其论辩体杂赋

战国中期,齐国的淳于髡长于论辩,善于调侃,在宫廷中成功地运用民间论辩讲诵伎艺,在滑稽诙谐的氛围中进行讽谏,留下了类似于对问体杂赋的作品。这些作品主要见于《史记.滑稽列传》和由淳于髡编辑而成的《晏子春秋》。故事性、论辩性和行文通俗、大致押韵,表明了这些作品的口诵性质。     

Incomplete equalization: The effect of tracking in secondary education on educational inequality

This paper tests whether the existence of vocationally oriented tracks within a traditionally academically oriented upper education system reduces socioeconomic inequalities in educational attainment. Based on a statistical model of educational transitions and data on two entire cohorts of Danish youth, we find that (1) the vocationally oriented tracks are less socially selective than the traditional academic track; (2) attending the vocationally oriented tracks has a negative effect on the likelihood of enrolling in higher education; and (3) in the aggregate the vocationally oriented tracks improve access to lower-tier higher education for low-SES students. These findings point to an interesting paradox in that tracking has adverse effects at the micro-level but equalizes educational opportunities at the macro-level. We also discuss whether similar mechanisms might exist in other educational systems.     

The elementary-school functioning of children with maltreatment histories and mild cognitive or behavioral disabilities: A mixed methods inquiry

This mixed methods inquiry examined the school functioning of elementary school-aged children with maltreatment histories and mild cognitive or behavioral disabilities. Quantitative analyses of linked social service and education administrative data bases of 10,394 children in Minnesota with maltreatment histories indicated that 32% were eligible for special education services. Of those children with maltreatment histories and identified disabilities, 73% had mild cognitive or behavioral disabilities. The most frequent primary disabilities categories were specific learning disabilities (33%) and emotional/behavioral disabilities (27%). Children with maltreatment histories and mild cognitive or behavioral disabilities scored significantly below children with maltreatment histories and no identified disabilities on standardized assessments of math and reading, and this gap increased with grade level for math. Qualitative interviews with 22 child welfare professionals and 15 educators suggested why some children with maltreatment histories, especially those with mild cognitive or behavioral disabilities, struggle in school. Risks to school functioning included children's and families' multiple unmet basic and mental health needs which can mask or overshadow children's mild disabilities; poor cross systems collaboration between child welfare, education and mental health systems; and inadequate funding, especially for mental health services. Protective factors included child engagement in school, parent engagement with child welfare services and a professional culture of cross-systems collaboration. Implications are discussed for holistic child, family and system-level interventions.     

How Effective are Interventions to Enhance Adherence to Psychiatric Medications? Practice Implications for Social Workers Working With Adults Diagnosed With Severe Mental Illness

This study integrates eight systematic reviews of adherence enhancement interventions to develop practice guidelines for social workers who work with adults who do not adhere to prescribed psychiatric medications. Findings indicate that existing investigations are disparate in their adherence definitions, methodologies employed, and sampling strategies, rendering it difficult to construct overall guidelines for social work practice. However, themes associated consistently with increased adherence are collaboration between clients and providers regarding medication decisions, consistent follow-up care, and a comprehensive network of professionals and caregivers who support clients in their use of medication to facilitate stabilization of mental health symptoms.
