Examining the association between Medicaid coverage and preterm births using 2010–2013 National Vital Statistics Birth Data

Reducing the number of preterm births is a high public health priority in the U.S. Preterm birth, affecting an estimated 380,000 infants annually, is a leading cause of infant mortality and morbidity and is associated with individual and systemic characteristics. Preterm birth is estimated to cost society $26 billion annually. Despite an elevated financial burden caused by preterm birth, very little is known about who bears these costs. This study seeks to understand the relationship between Medicaid and private insurance payment for preterm birth, using multiple years of vital statistics data, which for the first time since 2010 include information on payment source. The nationwide data cover births that occur in all settings, including non-hospital settings, and many maternal characteristics not available in other datasets, improving upon previous analyses. These data can be used to promote better Medicaid coverage of interventions known to be effective in reducing preterm births.

Intention to Leave the Profession: Welfare Social Workers Compared to Health Care and Community Social Workers in Israel

ABSTRACT

This study aimed to compare specific work related-factors (personal factor: length of work experience; structural factors: personal subjection to violence and fear of being subjected to violence; and psychological factors: professional quality of life—compassion satisfaction, burnout, and compassion fatigue) between welfare social workers (SWs) (n = 200) and health care and community SWs (n = 173). Furthermore, since the issue of turnover among SWs has important implications for the provision and programming of social services, the study also aimed to assess the relationship between these factors and SW intention to leave the profession. For the purpose of this study, online questionnaires were distributed to SWs working at social agencies and services. The findings suggest that the two categories of SWs showed a similarity with regard to the association between the personal and structural factors and intention to leave the profession. However, with regard to the psychological factors, the components of professional quality of life were found to operate differently in each category of SWs. It is suggested that future research examine other work-related factors and explore the intention to leave the profession among other social work specializations and employment sectors.     

中国和保加利亚的中产阶级发展模式

中国和保加利亚都是经历过社会主义制度之后并进行转型的社会,然而在各自的社会转型中,中产阶级的形成与发展又有什么差异和相同呢?各有什么特点和表征呢?为此我们想把双方的信息资料摆到了一起,我们很希望通过比较能反映出一个概貌,并能给两国研究者以启示,同时也希望能给两国学术交流做些有益的事.     

A simulation tool for modeling the influence of anatomy on information flow using discrete integrate and fire neurons

There are theories on brain functionality that can only be tested in very large models. In this work, a simulation model appropriate for working with large number of neurons was developed, and Information Theory measuring tools were designed to monitor the flow of information in such large networks. The model’s simulator can handle up to one million neurons in its current implementation by using a discretized version of the Lapicque integrate and fire neuron instead of interacting differential equations. A modular structure facilitates the setting of parameters of the neurons, networks, time and most importantly, architectural changes. Applications of this research are demonstrated by testing architectures in terms of mutual information. We present some preliminary architectural results showing that adding a virtual analogue to white matter called “jumps” to a simple representation of cortex results in: (1) an increase in the rate of mutual information flow, corresponding to the “bias” or “priming” hypothesis; thereby giving a possible explanation of the high speed response to stimuli in complex networks. (2) An increase in the stability of response of the network; i.e. a system with “jumps” is a more reliable machine. This also has an effect on the potential speed of response.     

Some Properties of Weighted Distributions in the Context of Repairable Systems

ABSTRACT

In this article we introduce some structural relationships between weighted and original variables in the context of maintainability function and reversed repair rate. Furthermore, we prove some characterization theorems for specific models such as power, exponential, Pareto II, beta, and Pearson system of distributions using the relationships between the original and weighted random variables.     

Predicting Maternal Resolution of Preterm Birth at One Month Corrected Age

Early maternal resolution with preterm birth was assessed at one month corrected age (CA), and potential maternal and infant characteristics that may be associated with early resolution were examined. Fifty‐five mothers of preterm infants (≤34 weeks) participated. Data regarding pregnancy, prenatal risk, delivery, infant's medical risk, maternal well‐being status, and infant's early developmental status were collected. Resolution was examined using the Reaction to Diagnosis Interview (RDI). A total of 38.2% of the mothers were classified as resolved. Only completion of antenatal corticosteroids (ACS) treatment and high prenatal risk significantly predicted maternal resolution. Early maternal resolution of preterm birth is associated with early knowledge regarding the preterm birth.     

Work-related factors associated with psychological distress among social workers

The current study assesses the association between several work-related factors and psychological distress among social workers (SWs) in Israel. The data were collected through structured questionnaires, administered to a sample of 494 SWs. The findings suggest that most of the examined work-related factors (namely, years of professional experience, personal work-related subjection to violence, burnout, compassion fatigue, and sense of coherence), with the exception of compassion satisfaction, significantly predicted psychological distress among SWs. The conclusion is that it is important to embed within the social work practice strategies for reducing sources of psychological distress (job demands) and increasing material, professional, and personal resources. Reducing the levels of psychological distress experienced by SWs will benefit not only themselves, but also their families and colleagues, as well as their clients. Moreover, this has potential benefits for the social work profession and for the general community.
