Community-Based Services and Depression from Person-Environment Fit Perspective: Focusing on Functional Impairments and Living Alone

ABSTRACT

Guided by the Person-Environment Fit perspective, we investigated the extent to which personal and environmental factors influence depression among community-dwelling adults. The data came from the special section about community-based service utilization in the 2012 Health and Retirement Study (N=1,710). Although community-based service was not significantly associated with depression after controlling for covariates, respondents with functional limitations and living alone were less likely to be depressed when using community-based services. This study demonstrates the different associations between community-based services and depression depending on personal needs. It discusses the importance of community-based services for aging-in-place policy, particularly among vulnerable populations.     

江苏省仪征市真州东园位置考证

东园是仪征历史上最著名的一座园林,也是中国宋代最著名的园林之一,在中国古代园林史上占有重要地位.梅尧臣、苏轼、王安石等人都曾经在园中游览,留下了优美的诗篇,欧阳修为它写了著名的散文《真州东园记》.虽然这座园林在清代已经消失,但是今天许多人士希望能够确定东园遗址的位置,重建这座园林,为仪征保留一份珍贵的历史文化遗产.由于年代久远,仪征当地的地形地貌发生了巨大变化,东园遗迹几乎完全消失;同时,文献中东园位置的记载也是十分简略的,因此,确定它的位置非常困难.在前人研究的基础上,通过查阅文献并结合实地调查,确定了东园遗址的准确位置和边界.东园遗址的位置在以今天文墩遗址为中心,真州城东翼城遗址的南侧,真州城东门遗址的东侧,清代儒学遗址的北侧,小教场遗址的西侧.     

公共艺术对构建和谐社会的理论审思

从多元文化视角及文化与社会的互动关系论述公共艺术对于构建社会主义和谐社会的作用,具有独特意义。公共艺术作为社会公众艺术,对于建设和谐的社会文化生态,塑造和谐的社会生存空间,促进人与人、人与自然、人与社会的整体和谐都具有十分重要的作用。当前,公共艺术与社会发展之间存在着诸多不协调的现象,需要从体制、意识、内涵等方面寻求突破。     

Toward General Principles for Resilience Engineering

Maintaining the performance of infrastructure-dependent systems in the face of surprises and unknowable risks is a grand challenge. Addressing this issue requires a better understanding of enabling conditions or principles that promote system resilience in a universal way. In this study, a set of such principles is interpreted as a group of interrelated conditions or organizational qualities that, taken together, engender system resilience. The field of resilience engineering identifies basic system or organizational qualities (e.g., abilities for learning) that are associated with enhanced general resilience and has packaged them into a set of principles that should be fostered. However, supporting conditions that give rise to such first-order system qualities remain elusive in the field. An integrative understanding of how such conditions co-occur and fit together to bring about resilience, therefore, has been less clear. This article contributes to addressing this gap by identifying a potentially more comprehensive set of principles for building general resilience in infrastructure-dependent systems. In approaching this aim, we organize scattered notions from across the literature. To reflect the partly self-organizing nature of infrastructure-dependent systems, we compare and synthesize two lines of research on resilience: resilience engineering and social-ecological system resilience. Although some of the principles discussed within the two fields overlap, there are some nuanced differences. By comparing and synthesizing the knowledge developed in them, we recommend an updated set of resilience-enhancing principles for infrastructure-dependent systems. In addition to proposing an expanded list of principles, we illustrate how these principles can co-occur and their interdependencies.     

A Simple Toxicokinetic Model Exhibiting Complex Dynamics and Nonlinear Exposure Response

Uncertainty in model predictions of exposure response at low exposures is a problem for risk assessment. A particular interest is the internal concentration of an agent in biological systems as a function of external exposure concentrations. Physiologically based pharmacokinetic (PBPK) models permit estimation of internal exposure concentrations in target tissues but most assume that model parameters are either fixed or instantaneously dose-dependent. Taking into account response times for biological regulatory mechanisms introduces new dynamic behaviors that have implications for low-dose exposure response in chronic exposure. A simple one-compartment simulation model is described in which internal concentrations summed over time exhibit significant nonlinearity and nonmonotonicity in relation to external concentrations due to delayed up- or downregulation of a metabolic pathway. These behaviors could be the mechanistic basis for homeostasis and for some apparent hormetic effects.
