An Empirical Study of a Peer Support System in Rehabilitation of Psychiatric Patients

The application of peer-support system in rehabilitation of psychiatric patients is explored from the perspective of recovery. This paper discusses the source of the recovery theory, the foundation and the factors of the peer support system, and its localized practice. This research presents an important path for peer support by building up an organization of mutual help among the mental-disease patients, a platform of mutual support among the families of these patients, and a social support network among the peer groups. It provides positive significance in the rehabilitation of the mental-disease patients.     

An Assessment of Juvenile Drug Courts’ Knowledge of Evidence‐Based Practices,Data Collection,and the Use of AA/NA

The use of evidence‐based practices (EBPs) has become a core component of juvenile drug courts (JDCs). This research, using a sample of JDCs listed with the National Association of Drug Court Professionals, tests two current assumptions in the field: 1) many JDCs do not use or are unaware of their use of EBPs and 2) JDCs tend to overuse sober support groups (e.g., AA/NA), which are thought to be inappropriate for youth. Results suggest that nearly all JDCs, in the sample, reported using EBPs; however, only about a quarter of them collected treatment data and knew the outcomes of the data. Also, only about half of the JDCs use sober support groups (predominantly AA/NA), and nearly all of the sober support groups were tailored toward youth. Overall, these findings suggest that the current assumptions in the field do not accurately reflect the practices reported by these JDCs. Implications are discussed.     

Automated Classification of Epiphyses in the Distal Radius and Ulna using a Support Vector Machine

The aim of this study was to automatically classify epiphyses in the distal radius and ulna using a support vector machine (SVM) and to examine the accuracy of the epiphyseal growth grades generated by the support vector machine. X‐ray images of distal radii and ulnae were collected from 140 Chinese teenagers aged between 11.0 and 19.0 years. Epiphyseal growth of the two elements was classified into five grades. Features of each element were extracted using a histogram of oriented gradient (HOG), and models were established using support vector classification (SVC). The prediction results and the validity of the models were evaluated with a cross‐validation test and independent test for accuracy (P_A). Our findings suggest that this new technique for epiphyseal classification was successful and that an automated technique using an SVM is reliable and feasible, with a relative high accuracy for the models.     

Classification of firing pin impressions using HOG-SVM

Crimes, such as robbery and murder, often involve firearms. In order to assist with the investigation into the crime, firearm examiners are asked to determine whether cartridge cases found at a crime scene had been fired from a suspect's firearm. This examination is based on a comparison of the marks left on the surfaces of cartridge cases. Firing pin impressions can be one of the most commonly used of these marks. In this study, a total of nine Ruger model 10/22 semiautomatic rifles were used. Fifty cartridges were fired from each rifle. The cartridge cases were collected, and each firing pin impression was then cast and photographed using a comparison microscope. In this paper, we will describe how one may use a computer vision algorithm, the Histogram of Orientated Gradient (HOG), and a machine learning method, Support Vector Machines (SVMs), to classify images of firing pin impressions. Our method achieved a reasonably high accuracy at 93%. This can be used to associate a firearm with a cartridge case recovered from a scene. We also compared our method with other feature extraction algorithms. The comparison results showed that the HOG-SVM method had the highest performance in this classification task.     

论诸法学流派对法律方法的理论支援

法律方法理论不仅受规范法学理论的制约和支持,而且也受其他法学流派的制约和支持。不同法学流派所支持的具体法律方法不尽相同。如价值法学之于价值衡量、社会法学之于事实替代、规范法学之于效力识别、经济分析法学之于利益衡量、多元论法学之于法律续造等,都更容易产生支持效果。尽管不同法学流派各自支持不同的法律方法,但这不否定某一法律方法受多个法学流派理论支援的情形,也不否定一个法学流派可以支持多种法律方法的情形。     

The intersubjective space–time of a Zulu choir/HIV support group in global perspective

This article draws from anthropology, conversation analysis, ethnomusicology, semiotics, and phenomenology, using the concept of intersubjectivity to model how the micro-organization of musical communication can be integral in social processes of support, identity maintenance, and activism amid structural inequality. This is based on ethnographic fieldwork in Durban, South Africa, with a Zulu gospel choir that functioned as a support group, activist organization, and performance troupe. Three distinct aspects (or levels) of intersubjectivity are discussed. The organization of these levels in music making is outlined through fine-grained discussion of how people with HIV coordinate bodies and voices in space as they make music together for each other and for international audiences. This article contributes to the further development of a musical semiotics, discussing how overlapping conceptualizations of intersubjectivity in multiple disciplines may be synthesized to analyze the performance of coordinated sonic action.     

基于VECM模型的中国货币政策调控房地产价格的有效性分析

该文从货币政策传导理论出发,选取货币供应量、利率、商品房销售价格指数建立向量误差修正模型（VECM）,运用Johansen协整分析、Granger因果检验等方法,对货币政策调控房地产价格的有效性进行分析。结果表明,长期来看,货币政策对房地产价格具有一定的调控效果;短期内,货币供应量变化对房价的影响相对较大,而利率调整不是调控房价的有效手段;利率政策有较长时滞,但对房价波动的贡献度大于货币供应量。     

行政成本概念鉴辨与重构

科学准确界定行政成本的定义与内涵是深刻认识行政成本的性质和范畴、深入研究行政成本、有针对性地有效控制行政成本的前提和基础。本文提出,行政成本是政府为了获得某种收益而必须为之付出的代价,即政府为了实现对社会的公共管理和为公众提供公共服务,所耗费的各种资源,以及由其所引发出的现今和未来一段时间的间接性损失。     

基于价格影响的期货市场操纵规制理论:反思与重构

在基于价格影响的期货市场操纵规制理论中,操纵被定义为故意制造人为价格的行为。人为价格的判断依赖于替代的价格标准,即执法实践中经常采用的参照系比较方法。这种判断方法不仅证明困难,且在行政处罚听证会或法庭辩论中容易受到质疑,导致期货市场操纵问题上的监管无力。要改变此种状况,首先,在判断操纵行为是否造成人为价格时,所关注的重点应当是影响市场价格的力量和因素,而非操纵行为造成的价格是否偏离了正常供求力量下应有的价格水平。其次,应当将意图作为操纵的核心要件,运用价格影响测试的分析框架,以行为人的不正当行为和其他直接或间接证据为支撑,并辅以经济或经验分析等方法进行综合判断。最后,当行为人的操纵行为未造成或未能证明造成人为价格时,引入试图操纵进行规制。     

Social support among releasing men prisoners with lifetime trauma experiences

High rates of lifetime trauma experiences exist among men incarcerated in US state and federal prisons. Because lifetime trauma experiences have been linked to problematic behavioral and psychiatric outcomes for incarcerated populations, trauma-informed interventions could improve post-release well-being of releasing men prisoners with trauma histories. Social support has consistently been found to have a positive impact on trauma-related outcomes in non-incarcerated populations. Therefore, it is reasonable to hypothesize that social support may be an important intervention component for releasing men prisoners with trauma experiences; yet, the relationship between trauma experiences, psychiatric and behavioral factors, and social support has received almost no attention in research with men prisoners. Using a probability sample of 165 soon-to-be-released men, the present study examined differences in certain demographic, criminal justice history, mental health, substance abuse, and social support (type, quality, amount, and source) variables between releasing men prisoners with and without lifetime trauma experiences. Results indicate that men with trauma histories had more negative social support experiences and fewer positive social support resources before prison than their counterparts. Men with trauma histories also had more lifetime experiences with mental health and substance use problems. On further investigation of the subsample of men with trauma histories, those who were older, had substance use disorders, and histories of mental health problems anticipated fewer post-release social support resources. Study findings underscore the nuances of social support for men prisoners with trauma experiences and point to implications for future directions in targeted trauma-informed intervention development for releasing men prisoners.
