On some generalized farlie-gumbel-morgenstern distributions-II regression,correlation and further generalizations

Regression and correlation properties of the generalized Farlie-Gumbel-Morgenstem distributions introduced in Johnson and Kotz (1975) are studied. Further generalizations of these distributions are considered.     

Collaboration as a strategy to accelerate change

Abstract

As a strategy, collaboration is increasingly recognized by governments and by library partnerships as a critical component in achieving next generation change, particularly where it leads to trust in shared infrastructure, collections and expertise. Collaboration reduces the risks to the library industry. These risks stem from the capability of libraries to respond rapidly to changing technology and user needs, and to drive an increase in the digitization of collections and ensure the preservation of digital content. The ten National, State and Territory Libraries of Australia and New Zealand have committed to collaboration to accelerate change in their libraries and to new principles of open and easy access to information. The challenge is to bring these elements together as a transformed and implemented service.     

圈层协作:尺度政治视域下全国性应急防疫的治理逻辑

国家治理是对具备复杂性的地理社会空间进行的系统化、整体化的全局运作。各尺度治理单元依据包含与被包含关系形成了特定的“圈层结构”。在防疫应急治理中，面临着疫情防治与社会风险防控的双重治理任务，且双重任务目标都是在特定尺度的地理空间内实现的。国家、市域与社区三种尺度的治理单元需要发挥互动协作作用。以此为鉴，文章认为政治地理意义上的国家治理，需要发挥各尺度治理单元的治理效能，有效地建立起适应各尺度治理单元运转的治理共同体。未来应当按照“圈层协作”的思维谋划国家治理现代化。      

Child Welfare and Alcohol and Other Drug Treatment (AOD): Bridging the Gap to Comprehensive Services

ABSTRACT

Chemical addiction is a significant factor in child abuse and neglect (U.S. Department of Health and Human Services [DHHS], 1999). Although research has indicated that an alliance between the child welfare and alcohol and other drugs (AOD) treatment fields is the best way to effectively address chemical addiction within families, collaboration has not generally been established. The lack of collaborative relationships between the child welfare and AOD fields can be attributed to a number of different factors. Similarities in proposed interventions for collaborative efforts between AOD treatment and child welfare agencies can be found throughout the literature. The establishment of a truly collaborative partnership between AOD treatment and the child welfare system is a necessary step towards achievement of functional and healthy families, a goal common to both disciplines.     

Understanding dissociation in relation to child trauma,mental health needs,and intensity of services in child welfare: A possible missing link

Abstract

While there is limited research on the role of dissociation among children and adolescents, emerging evidence links child trauma history, dissociation, risk behaviors, and other negative outcomes among youth. This study examined dissociation in relation to mental health needs and intensity of services among a large sample of youth in Illinois child welfare, upon entry into care and in residential treatment settings. The Child and Adolescent Needs and Strengths (CANS), a comprehensive, trauma-informed assessment strategy and information integration/planning tool was the primary measure. This study included two overall samples of child welfare-involved youth, ages 3–18: at entry into care (N?=?27,737) and in residential treatment (N?=?5,758). Findings indicated that rates of clinically significant dissociation were generally highest among younger youth (under age 14) and among youth with more cumulative and severe trauma. Dissociative youth were significantly more likely to exhibit several risk behaviors (e.g., fire setting and self-harm) and mental health symptoms (e.g., psychosis and somatization). Those youth with significant dissociation at entry into care were more likely to be psychiatrically hospitalized, placed into residential treatment, with greater likelihood of placement disruptions within the 2 years following entry into care. Implications of these findings are discussed in terms of the value of identifying and assessing dissociation and other trauma-related symptoms that may be less recognized but can be linked to high-risk behaviors and other negative outcomes within child welfare and across child-serving systems. Understanding dissociation may be an important component of training, service/treatment planning, and clinical care within child-serving systems.

Preventing HIV/AIDS Among Trinidad and Tobago Teens Using a Family-Based Program

Summary

This paper describes a family-based HIV/AIDS prevention project currently underway in Trinidad and Tobago—an English speaking twin-island nation in the Caribbean. The project involves a partnership between U.S.-based researchers and a social service agency on the Islands. It describes the development and adaptation of the intervention and reports preliminary outcomes from a pilot intervention (n= 32). Findings indicate high participant retention; statistically significant pre to posttest changes in HIV/AIDS knowledge and awareness; parent/youth discussions at home; condom self-efficacy; and parental monitoring. Findings are discussed within the context of collaborative HIV/AIDS prevention research.     

An Integrated Approach for Modeling Sustainability Risks in Freight Transportation Systems

Integrating sustainability into freight transportation systems (FTSs) is a complex and challenging task due to the sheer number of inherent sustainability risks. Sustainability risks disrupt the economic, social and environmental objectives of freight operations and act as impediments in the development of sustainable freight transportation systems. The area of sustainability risk management is still unexplored and immature in the operational research domain. This study addresses these research gaps and contributes in a threefold manner. First, a total of 36 potential sustainability risks related to FTSs are identified and uniquely classified into seven categories using a rigourous approach. Second, the research proposes two prominent perspectives, namely, ontological and epistemological perspectives to understand risks and develops a novel framework for managing sustainability risks in FTSs. Third, a novel approach by integrating fuzzy evidential reasoning algorithm (FERA) with expected utility theory is developed to quantitatively model and profile sustainability risk for different risk preferences, namely, risk-averse, risk-neutral, and risk-taking scenarios. The proposed FERA is a flexible and robust approach, which transforms the experts’ inputs into belief structures and aggregates them using the evidence combination rule proposed in Dempster–Shafer theory to overcome the problem of imprecise results caused by average scoring in existing models. A sensitivity analysis is conducted to demonstrate the robustness of the proposed model. Unlike conventional perception, our study suggests that most of the high priority sustainability risks are behaviorally and socially induced rather than financially driven. The results provide significant managerial implications including a focus on skills development, and on social and behavioral dimensions while managing risks in FTSs.     

The guide to available mathematical software problem classification system1

A vast collection of reusable mathematical and statistical software is now available for use by scientists and engineers in their modeling efforts. This software represents a significant source of mathematical expertise, created and maintained at considerable expense. Unfortunately, the collection is so heterogeneous that it is a tedious and error-prone task simply to determine what software is available to solve a given problem. In mathematical problem solving environments of the future such questions will be fielded by expert software advisory systems. One way for such systems to systematically associate available software with the problems they solve is to use a problem classification system. In this paper we describe a detailed tree-structured problem-oriented classification system appropriate for such use.
