Statistical analysis of the usage of a computer system

This paper is concerned with an empirical investigation of a common and important type of computer system and usage in business applications, viz., querying, updating and modifying a large database. Specifically, it describes the analysis of data collected from such an application and addresses two issues. Firstly, it assesses the applicability of statistical assumptions that underlie certain widely-used queueing theory models for computer systems usage. Secondly, it investigates measures of usage, as well as relationships among them, that may serve as appropriate bases for a pricing scheme for usage of computer systems of the type considered here.     

Implementing Fall Prevention Guidelines with Vulnerable Older Adults: The Social Work Role

Falls are the leading cause of injury among the older adult population, resulting in costly and devastating aftermaths. National fall prevention guidelines (FPGs) have been established to assist healthcare professionals with addressing fall risk, but little is understood about the extent to which FPGs have been implemented by social workers. Social workers, however, may beuniquely positioned to implement FPGs with older adults due to their expertise in care coordination and home- and community-based service settings. This conceptual paper addresses the timely issue of fall prevention and social workers’ potential role in implementing FPGs to address fall risk.     

Safety of a meningococcal group B vaccine used in response to two university outbreaks

Objective: To assess the safety of meningococcal group B (MenB)-4C vaccine. Participants: Undergraduates, dormitory residents, and persons with high-risk medical conditions received the MenB-4C vaccine two-dose series during mass vaccination clinics from 12/2013 through 11/2014. Methods: Adverse events (AEs) were identified by 15 minutes of observation postvaccination, spontaneous reports, surveys, and hospital surveillance. Causality was assessed for serious adverse events (SAEs). Results: 16,974 persons received 31,313 MenB-4C doses. The incidence of syncope during the 15-minutes post-dose 1 was 0.88/1000 persons. 2% of participants spontaneously reported an AE (most common were arm pain and fever). 3 SAEs were suspected of being caused by the vaccine, including one case of anaphylaxis. Conclusions: Most AEs reported were nonserious and consistent with previous clinical trial findings. Measures to prevent injury from syncope and to treat anaphylaxis should be available wherever vaccines are administered. Our safety evaluation supports the use of MenB-4C in response to outbreaks.     

An Examination of Reward Probability and Delivery Delays on Employee Performance

ABSTRACT

The effects of delay to delivery of earned monetary rewards were evaluated in program support employees. During study 1, an immediate reward delivery condition was implemented. During study 2, employees were exposed to increasing delays to reward delivery (i.e., 1, 2, 4, 8, 16, and 32 days). Employees continued to respond at high levels up to a 32-day delay. Study 3 held the 32-day delay constant but also evaluated three different probabilities of receiving the rewards: 1.0, .5, and .1. Employees continued to respond during delays but decreased responding when the probability of receiving the rewards decreased.     

制造企业服务化路径选择研究

服务化已经成为制造企业获取和保持竞争优势的重要途径，其本质是企业价值链的延伸，既包括投入服务化，又包括产出服务化。在实施服务化战略时，制造企业可以选择将投入、产出服务功能内部化或外部化，即自营或外包。从产品层面构建理论模型，比较研究制造企业的四种服务化路径：（1）外包投入服务和产出服务；（2）外包投入服务，自营产出服务；（3）自营投入服务，外包产出服务；（4）自营投入服务和产出服务。首先，通过分析需求质量弹性和质量成本系数、制造企业产品及服务的质量和价格、生产性服务企业服务的质量和价格以及制造企业与生产性服务企业的市场基础等模型变量，得到制造企业在每种服务化路径下的最大化利润。其次，通过比较每种路径下的最大化利润，得到路径选择的临界条件。最后，通过数值实验和算例分析，验证了模型的有效性和实用性。研究结果表明，何种路径成为更优的选择取决于制造企业的自身条件和所面临的市场环境。总体而言，在质量成本系数足够大于需求质量弹性的前提下，生产性服务企业所提供投入服务或产出服务的市场基础越大，将该种服务外部化的预期利润越高。研究结果将为制造企业的服务化路径选择提供理论依据和解决方案。     

Social Service Research and Religion

Abstract

Development of accountability standards to demonstrate cause and effect relationships are gaining rapid advancement in the field of social sciences. Many governmental agencies, foundations, and other funders have developed approaches that require organizations to utilize science-based programs and incorporate evaluative methods to show improved outcomes and cost benefits to society. This article will examine the need for increased accountability in developing effective interventions by faith-based organizations in the delivery of social service interventions. Recently, there has been a strong movement toward governmental funding for faith-based institutions to provide social services, although there has been inadequate scientific data to demonstrate that approaches implemented are effective in meeting needs or yielding favorable outcomes. Similarly, many faith-based organizations provide innovative and effective programs that could serve as model programs if there was appropriate empirical evidence. This article will discuss how rigorous evaluative approaches such as randomized clinical control trials can produce scientific data on program effectiveness. We will use a case example in the field of drug and alcohol treatment to illustrate these points.     

Does the Andersen Behavioral Model of Health Services Use predict college students’ use of on-campus mental health services?

Abstract

Objective: 10–50% of college students meet the diagnostic criteria for one or more mental illnesses; unfortunately, less than half seek treatment. This study assessed the predictive power of specific variables on students’ use of on-campus mental health resources using the American College Health Association’s National College Health Assessment (ACHA-NCHA) II. Participants: Respondents included undergraduate and graduate students ages 18–35?years (n?=?96,121). Methods: We analyzed data from the ACHA-NCHA II Fall 2014 and Spring 2015. Andersen’s Behavioral Model of Health Services Use enabled selection of predisposing, enabling, and need predictor variables; these were analyzed individually and collectively. Results: Predisposing, enabling, and need variables accounted for 9%, 2.3%, and 17% of the overall variance. Significant variables associated with a student’s decision to access on-campus mental health services accounted for 23% of variance total. Conclusions: This insight could allow universities to better recognize students at-risk for needing but not accessing mental health services.     

Social work education in Spain: evaluation and challenges for a new generation of social workers

ABSTRACT

The European social integration model was built on two main pillars: employment and access to the welfare state. European social work education was mainly oriented to training professionals in order to promote this inclusion through case management and the provision of benefits. This influence was very intense in the curricular content of Spanish social work programs. The new social risks and the European convergence in higher education have promoted curricular changes, but is it enough?. This paper aims to identify the content and limits of current social work education in Spain. To this end, a comparative analysis of social work education in public universities of Spain was performed. This information has been contrasted with professionals, teachers and social work students. The results evidence the gap of these contents with the real professional needs. This paper proposes several alternatives and approaches in new intergenerational methodologies and technological tools to train a new generation of social workers     

A formative assessment of gender awareness and ability of staff based on the service programs of the All-China Women's Federation: The case of the “3861 My Home” program

In order to achieve “gender mainstreaming” which is a global strategy to promote the development of women, it has in recent years been a major task for the All-China Women's Federation (ACWF) to improve the gender awareness and ability of policy makers and implementers. Thus, researchers should constantly propose and evaluate various possible attempts to improve gender awareness and the ability of individuals. There are few empirical studies on the assessment of gender awareness and the improvement of the ability of staff who have been trained and educated. Research studies focusing on the promotion of gender-sensitive awareness and ability of staff by participating in programs are even rarer.This study presents a specific case, namely the evaluation of promoting social service workers’ gender awareness and ability within the implementation of the “3861 My Home” program. Based on this case, this study examines how to promote gender awareness and ability of social service workers through the implementation of the service program of Women's Federation, and also assesses the quality of the results of this implementation. Moreover, this study also contributes to the literature pertaining to assessing the development of social service workers’ gender awareness and ability. In addition, the study provides an option for enhancing the gender awareness and ability of social service workers in addition to training: The participatory learning or action pertaining to gender awareness and ability based on the Women's Federation programs are able to effectively improve the gender awareness and ability of staff.
