Impact of mindful self-care and perceived stress on the health related quality of life among young-adult students in West Virginia

ABSTRACT

There are substantial gaps in research on Health Related Quality of Life (HRQoL) in students aged 18 and above in West Virginia. The purpose of this study is to explore the associations between mindful self-care, perceived stress, and the HRQoL in this population. We conducted a cross-sectional study between March and April 2017. We included participants who were students, aged 18 years and above, living in West Virginia and were able to answer online questions in English. Data was obtained from an online survey using a structured questionnaire, including the SF12v2®, mindful self-care scale- SHORT, and Perceived Stress Scale (PSS)-10. We applied linear regressions to determine the predictors of HRQoL (physical health and mental health) using SF12v2®. 194 participants met the inclusion criteria of the study. Mindful self-care was negatively associated with perceived stress. Better mindful self-care mediated the relationship between perceived stress and psychological well-being, controlling for gender, age, race, marital status, education level, annual household income, and chronic disease status. Perceived stress and mindful self-care were not related to the physical well-being. Better mindful self-care may safeguard against perceived stress among students aged 18 years and above. Our findings in this study recommend more mindfulness-based interventions targeted to this subpopulation to improve psychological well-being.     

Semiparametric regression of clustered current status data

This paper discusses regression analysis of clustered current status data under semiparametric additive hazards models. In particular, we consider the situation when cluster sizes can be informative about correlated failure times from the same cluster. To address the problem, we present estimating equation-based estimation procedures and establish asymptotic properties of the resulting estimates. Finite sample performance of the proposed method is assessed through an extensive simulation study, which indicates the procedure works well. The method is applied to a motivating data set from a lung tumorigenicity study.     

工业取用水监测奇异数据挖掘与重构方法

提高工业取用水监测数据质量是目前国家水资源监控能力建设的重要内容,而奇异值问题已成为影响监测数据质量的关键短板。本文在解析现阶段工业取用水监测数据奇异值主要类型基础上,以国家水资源管理系统数据库中工业取用水监测数据为样本,利用小波变换模极大值模型提取工业取用水监测数据时频变化特征,并利用傅里叶函数对其残差序列进行修正,进而运用相对误差控制方法挖掘监测数据奇异值。在此基础上,采用混沌粒子群优化的最小二乘支持向量机模型重构填补奇异值数据。研究结果表明：小波变换模极大值模型能够较好地提取工业取用水监测数据序列的时频变化特征,但是同时容易导致监测数据的信息损失,利用傅里叶函数对小波变换进行残差修正则可进一步提升取用水监测数据序列的特征提取效果;以小波变换模极大值特征序列为基础,通过相对误差控制可实现对监测数据奇异值的高效挖掘;对于挖掘出的奇异值重构填补问题,可选取混沌粒子群优化的最小二乘支持向量机模型,其重构精度要优于多项式曲线拟合等传统统计学方法和普通最小二乘支持向量机模型。上述工业取用水监测数据奇异值挖掘重构策略为现阶段国家水资源监控能力建设的推进提供了重要技术方法支持。     

The Human Capital Model of Selection and Immigrant Economic Outcomes

This article examines the trends in the economic advantage that highly educated immigrants hold over less educated immigrants in Canada, focusing on the differences between short‐run and longer‐run outcomes. Using data from the Longitudinal Immigration Database covering the period from the 1980s to the 2000s, this study finds that the relative entry earnings advantage that higher education provides to new immigrants has decreased dramatically over the last 30 years. However, university‐educated immigrants had a much steeper earnings trajectory than immigrants with trades or a high school education. The earnings advantage among highly educated immigrants increases significantly with time spent in Canada. This pattern is observed for virtually all immigrant classes and arrival cohorts. The results suggest that short‐run economic outcomes of immigrants are not good predictors of longer‐run results, at least by educational attainment. The implications of these findings for immigration selection policy are discussed in the conclusion.

西藏农村公共产品特殊性研究

公共产品的供给能够产生一定效用,但就不同区域而言,自然环境、地理位置、经济能力、个体素质等不尽相同,不仅对公共产品的需求类型和程度存在差别,而且效用程度也存在差异性。西藏农村的特殊性使得公共产品的一些属性发生变化,更具有复杂性和动态不确定性,某些私人产品转化为准公共产品,某些准公共产品转化为纯公共产品。因此,西藏农村公共产品供给应注意完善西藏农村公共财政体系,加大转移支付力度;适应西藏农牧区特殊性情况,优化公共产品供给结构;衔接农牧民实际需求,构建合理公共产品供给决策机制;发挥非正式组织作用,实现西藏农村公共产品供给多元化。     

四川少数民族人口发展路径探析

从人口数量、质量、结构三个方面分析四川少数民族人口发展现状,发现少数民族人口发展与区域资源环境、经济社会发展不协调带来了诸多问题,如人口增长过快导致的人均耕地锐减、环境恶化、就业压力增大,人口质量难以满足经济社会发展的需要,人口城市化滞后的消极效应等。为此,实现少数民族人口现代化的路径需控制人口数量、提高人口素质、推进人口城市化。
