航位推算系统非线性过程处理新方法研究

针对航位推算系统中利用扩展Kalman滤波方法解决非线性问题在算法复杂性上的缺陷和精度上的不稳定性,该文从数据预先处理的角度出发,合理规避线性化过程,提出一种充分利用现成Kalman滤波公式的方法,即数据进入滤波器之前就预先进行处理,获得每一组量测值,按照极坐标-笛卡儿坐标的转换方式转为相应的位置信息,再按照标准的Kalman滤波公式构建滤波器,进行状态的最优估计。计算机仿真结果证明该算法的有效性。     

Perceived professional standards and roles of public relations in China: Through the lens of Chinese public relations practitioners

As the first quantitative examination of perceived public relations professional standards in China using an online survey, this study was designed based on the standards of professional standards inventory Cameron, Sallot, & Lariscy (1996) constructed and tested among practitioners in the U.S. The survey results suggest six dimensions of perceived standards of professional performance: (1) role and function in organizational strategic planning, (2) sufficiency in professional training and preparedness, (3) gender and racial equity, (4) situational constraints, (5) licensing and organizational support, and (6) participation in the organizational decision-making team. Four dimensions of public relations roles were also identified by the survey participants: (1) brand promotion facilitator, (2) public information specialist, (3) media relations counsel, and (4) conflict management expert. Primary practice area was found to affect how Chinese practitioners perceive the six clusters of professional standards and the four identified public relations roles. These findings provide insights for both practitioners and researchers on how Chinese public relations practitioners view public relations as a profession and how the profession currently holds its professional standards in China.     

Fostering secure attachment in low- and middle-income countries: Suggestions for evidence-based interventions

Children struggling with the effects of trauma in low- and middle-income countries (LMIC) face a substantial mental health resource gap that limits their opportunities for positive psychosocial development. Multidisciplinary interventions working to close this gap may benefit from incorporating an empirically supported treatment (EST) into their approach that targets a universal mechanism implicated in resilience, like attachment. ESTs should be selected based on their level of empirical support and cultural adaptability, and then modified on the basis of qualitative evaluations conducted with the local population and stakeholders. This paper will provide an overview of attachment as a mechanism of resilience, a critical analysis of existing attachment-based ESTs, and recommendations for overcoming EST implementation barriers in LMIC.     

A Postmodern Critique of Societal Discourses of Male Violence in Interpersonal Family Relationships: A Balancing Act for Social Work

In recent years, treatments of family violence have tended to be built around conventional discourses suggesting that men are major initiators in instances of interpersonal violence. Utilizing a postmodernist analysis, we assess societal discourses that continue to give life to this narrow conceptualization of interpersonal violence. We also examine literature suggesting that both men and women resort to violence to resolve relationship difficulties and suggest that a more holistic and inclusive approach to understanding interpersonal violence is critical for social workers committed to social justice and a balanced understanding of the contextual nature of human problems.     

孟子内圣之道探赜

每个人本来具有的恻隐、羞恶、恭敬、是非之心是内圣之道的入手处,而此四心所本即为至善之心.体悟至善之心要从修心、知言、养气上下手,内圣之道由浅而深的六个次第是:善、信、美、大、圣、神.     

Factors That May Influence Parent Treatment Decision Making for Young Children with Autism Spectrum Disorder

ABSTRACT

The number of interventions available for children with autism spectrum disorder (ASD) has expanded greatly in recent years, although relatively little is known about the factors that influence family caregivers as they make treatment decisions for their children. This study involved a statewide survey of parents of young children with ASD to examine the relative weights of the factors that influenced their treatment decisions. Results suggested that caregivers rely on their own intuition for much decision making, although selected professionals are also influential. Implications for professionals working with children with ASD and their families are discussed.     

The Role of Social Workers in the Treatment of Addictions

Abstract

This article describes the history of social workers' involvement in the treatment of addictions in the United States. Beginning with Mary Richmond, the “mother of social casework,” social workers have played an increasingly important role in the treatment of individuals with alcohol and other drug problems and of their family members. Today, social workers are important players not only in program development, administration, and treatment of chemical addictions, but also in “process” addictions, such as eating disorders and gambling. Moreover, social workers are increasingly involved in addictions research and policy arenas.     

A process capability index with reliable confidence intervals

A well-know process capability index is slightly modified in this article to provide a new measure of process capability which takes account of the process location and variability, and for which point estimator and confidence intervals do exist that are insensitive to departures from the assumption of normal variability. Two examples of applications based on real data are presented.     

An Evaluation of Simulations in Developmental Disabilities (SIDD): Instructional Software that Provides Practice in Behavioral Assessment and Treatment Decisions

ABSTRACT

Simulations in Developmental Disabilities (SIDD) is a multimedia computer program designed to provide undergraduate psychology students with practice in making assessment and treatment decisions. Eighteen undergraduate psychology students participated in an experiment to test the instructional effectiveness of SIDD. Post-test scores were significantly higher in the experimental group who received training with SIDD than in a control group who did not receive training. The students also rated the software positively. Future strategies to further evaluate the software are discussed.
