Acculturation and Stress in a Low-Income Puerto Rican Community

Abstract

In this study, the acculturative stress experienced by Puerto Rican migrants to the urban U.S. is examined. Acculturative stress is defined as length of residence in a novel cultural environment while lacking psychosocial resources to support adaptation to that environment. In a sample of 67 patients seen in a public health nursing agency, it was found that acculturative stress was associated with poorer health status, more behavioral problems, and higher levels of ethnomedical belief. The implications of these results for research on stress and adaptation are discussed.     

Highly Improved Thermal Properties of Hydroxyl‐Containing Polymers via Modification by Benzoxazine Groups

Isocyanate functional benzoxazine (NCO‐4HBA‐a) is used for coupling with hydroxyl‐group‐containing molecules. Glycerol is used in a model reaction to study the urethane bonds formed between the NCO‐4HBA‐a and the glycerol's hydroxyl groups. The model supports a reaction between NCO‐4HBA‐a and poly(vinyl alcohol) (PVA), which leads to an improved char yield, determined by thermogravimetric analysis. Glycerol‐based benzoxazine is also an attractive benzoxazine synthesized from the products of biofuel production. Upon functionalization with benzoxazine and subsequent thermal treatment, the hydroxyl‐containing polymer gains thermal stability shown by improved char yield of polybenzoxazine cross‐linked PVA.

The Commerce and Crossover of Resources: Resource Conservation in the Service of Resilience

Conservation of resources (COR) theory was originally introduced as a framework for understanding and predicting the consequences of major and traumatic stress, but following the work of Hobfoll and Shirom (1993), COR theory has been adopted to understanding and predicting work‐related stress and both the stress and resilience that occur within work settings and work culture. COR theory underscores the critical role of resource possession, lack, loss and gain and depicts personal, social and material resources co‐travelling in resource caravans, rather than piecemeal. We briefly review the principles of COR theory and integrate it in the crossover model, which provides a key mechanism for multi‐person exchange of emotions, experiences and resources. Understanding the impact of resource reservoirs, resource passageways and crossover provides a framework for research and intervention promoting resilience to employees as well as to organizations. It emphasizes that the creation and maintenance of resource caravan passageways promote resource gain climates through resource crossover processes. Copyright © 2014 John Wiley & Sons, Ltd.     

The National Cancer Informatics Program (NCIP) Annotation and Image Markup (AIM) Foundation Model

Knowledge contained within in vivo imaging annotated by human experts or computer programs is typically stored as unstructured text and separated from other associated information. The National Cancer Informatics Program (NCIP) Annotation and Image Markup (AIM) Foundation information model is an evolution of the National Institute of Health’s (NIH) National Cancer Institute’s (NCI) Cancer Bioinformatics Grid (caBIG®) AIM model. The model applies to various image types created by various techniques and disciplines. It has evolved in response to the feedback and changing demands from the imaging community at NCI. The foundation model serves as a base for other imaging disciplines that want to extend the type of information the model collects. The model captures physical entities and their characteristics, imaging observation entities and their characteristics, markups (two- and three-dimensional), AIM statements, calculations, image source, inferences, annotation role, task context or workflow, audit trail, AIM creator details, equipment used to create AIM instances, subject demographics, and adjudication observations. An AIM instance can be stored as a Digital Imaging and Communications in Medicine (DICOM) structured reporting (SR) object or Extensible Markup Language (XML) document for further processing and analysis. An AIM instance consists of one or more annotations and associated markups of a single finding along with other ancillary information in the AIM model. An annotation describes information about the meaning of pixel data in an image. A markup is a graphical drawing placed on the image that depicts a region of interest. This paper describes fundamental AIM concepts and how to use and extend AIM for various imaging disciplines.     

医学特藏资源的构建及其在医学人文素质教育中的价值

医学特藏资源是医学图书馆提供差异化服务的突破点,也是医学图书馆参与医学人文素质教育的重要资源。在抗击肆虐全球的新冠肺炎疫情的过程中,医学界和其他社会各界都产生了大量有价值的史料,复旦大学图书馆医学馆抓住机会建设抗击新冠肺炎疫情专题史料库相关特藏资源并展出,取得了很好的传播效果。通过介绍这一专题特藏资源的建设经验,为同行建设医学特藏资源、促进医学人文素质教育提供借鉴。
