Adapting an evidence-based model to retain adolescent study participants in longitudinal research

Maintaining contact with and collecting outcome data from adolescent study participants can present a significant challenge for researchers conducting longitudinal studies. Establishing an organized and effective protocol for participant follow-up is crucial to reduce attrition and maintain high retention rates. This paper describes our methods in using and adapting the evidence-based Engagement, Verification, Maintenance, and Confirmation (EVMC) model to follow up with adolescents 6 and 12 months after implementation of a health program. It extends previous research by focusing on two key modifications to the model: (1) the central role of cell phones and texting to maintain contact with study participants throughout the EVMC process and, (2) use of responsive two-way communication between staff and participants and flexible administration modes and methods in the confirmation phase to ensure that busy teens not only respond to contacts, but also complete data collection. These strategies have resulted in high overall retention rates (87–91%) with adolescent study participants at each follow-up data collection point without the utilization of other, more involved tracking measures. The methods and findings presented may be valuable for other researchers with limited resources planning for or engaged in collecting follow-up outcome data from adolescents enrolled in longitudinal studies.     

Maintaining front-line workers in child protection: a case for refocusing supervision

This paper suggests that a refocusing of supervision be seen as one possible strategy for lowering high attrition rates among child protection workers. Research findings from a qualitative study undertaken in two rural regions in the State of Victoria, Australia illustrate that the current model of supervision gives insufficient attention to the emotional intrusiveness of the work, to building resilience in workers and the implications of adult learning theory. An argument is made for a refocusing of supervision which moves beyond task, encompassing much of what is already known from the supervision literature. The supervisor can be thought of as a messenger who must send and receive messages to and from workers. What message is sent and how supervisors respond to what they receive are critical if the objective is to retain front-line staff. Critically, the supervisor must affirm both the merit and necessity of exploring the impact of feelings and thoughts on action and perception. A key message for supervisors to deliver is the value of individual workers to the organization, leading to increased self-esteem and self-efficacy. The paper also argues for adult learning via reflective supervision. This change to supervision involves a fundamental shift in organizational priorities and an acceptance throughout of the impact of anxiety on all those working in this field.

Sustaining transitions from welfare to work: the perceptions of employers and employment service providers

Successive Australian Governments have sought to improve the capacity of the employment service system to build jobseekers' skills and capabilities and to promote transitions from income support to paid work. Yet despite these efforts, many jobseekers experience only short periods of employment, moving repeatedly between joblessness and positions with low skill requirements, low pay and few or fluctuating hours. This article explores ways to achieve more sustained transitions from welfare to work for disadvantaged jobseekers. We draw on data from a qualitative study of employment service providers who assisted jobseekers into work and the managers in the organisations that employed them. These informants' perspectives underline the importance of improving the quality of jobs that require low levels of skills and experience and demonstrate some ways employers and employment services can better work together and provide more enduring and effective forms of support.     

Achieving high quality and long‐lasting matches in youth mentoring programmes: a case study of 4Results mentoring

Mentoring programmes show significant promise for enhancing the well‐being of youth with complex needs. Research indicates that high quality mentoring, although difficult to achieve, positively impacts youth development across behavioural, social, emotional and academic domains. The difficulty of sustaining long‐term matches between mentors and youth, however, remains an important concern for the field of mentoring, as foreshortened matches can be harmful to youth. The 4Results mentoring programme has been identified as a Promising Practice through the Washington State Inventory of child‐serving behavioural and mental health programmes and has developed a unique infrastructure to support critical programme values such as match longevity. In 7 years, the programme has successfully retained 98% of mentors for at least 1 year with an average match length of 3.7 years. The following article describes the programme's guiding philosophy and approach to recruiting and training mentors in the context of existing best practices research.     

Routes to Part‐Time Management in UK Service Sector Organizations: Implications for Women’s Skills,Flexibility and Progression

This article examines the implications of part‐time working for mothers, particularly with regards to their occupational mobility and acquisition of skills, in UK service sector organizations following the implementation of the Part‐time Workers’ Directive in 2000. Through qualitative interviews with women and their managers in five hospitality workplaces, this article explores whether part‐time workers are potentially the ‘losers’ in the ‘winner‐takes‐all’ approach to career development. Discussions focus upon the extent to which part‐time workers can access career paths or, alternatively, whether part‐time management positions are the reserve of highly skilled women who are able to negotiate reduced hours after obtaining a management position full time. In conclusion, this article distinguishes between two forms of working‐time flexibility, which are named optimal and restrictive. The implications of these alternative types of flexibility, in terms of access to skill acquisition and occupational mobility, are then addressed.

Are case management services associated with increased utilization of adolescent mental health treatment?

Retention in treatment is one of the strongest predictors of positive mental health outcomes. Adolescents, however, are particularly challenging to retain in mental health treatment. Concurrent case management services may offer one strategy for retaining youth in mental health treatment as it aims to reduce barriers to services, coordinate multiple services, and establish a consistent relationship between each client and a single contact person. This study combines three extant data sources from the state of Kansas to examine whether youths' participation in case management is associated with increased utilization of individual and group mental health treatment, controlling for client satisfaction, severity of mental health symptoms, and demographic factors. Linear regression results indicate that participation in case management services predicts increased utilization of both individual and group mental health treatment. Case management may be a useful tool for retaining adolescent clients in mental health services. Practical implications for community mental health service delivery are discussed.     

一种改进的聚合物驱孔隙网络模型

基于幂律流体在圆管中的流动模型,建立了幂律流体剪切率与流速之间的关系式。对关系式进行校正并代入Carreau 模型中,得到了改进的Carreau 流体有效黏度模型。新模型中有效黏度是流速的函数,将原来的非线性问题简化为线性问题。应用新建立的有效黏度模型,综合考虑聚合物渗流机理建立聚合物驱微观模拟模型。进行了聚合物驱微观模拟,统计分析了聚合物驱后剩余油的微观分布规律。计算结果表明,聚合物驱后剩余油更趋分散：网络状剩余油体积比例明显减少,但油水混合状、孤粒/孤滴状、斑块状剩余油体积比例都有所提高。     

The racial politics of STEM education in the USA: interrogations and explorations

ABSTRACT

This special issue brings together a mix of early-career, mid, and senior scholars to critically examine current realities of, and boldly imagine future possibilities for, STEM education in the lives of racially minoritized children in the United States. Given the implicit and sometimes explicit aspirations of STEM education to be a counteracting force against racialized injustice, how do students and communities of color experience and make sense of STEM reforms/initiatives? By examining a broad range of STEM contexts including mathematics, computer science, science and environmental science education, and through a diversity of methodological approaches, this special issue aims to contribute to a scholarly conversation about how racialized power intersects with the larger themes and foci of STEM education. In our introduction, we both highlight broad themes of the issue, and offer possible directions for future research at the intersections of race, power, and STEM.
