破解“垃圾围城”之困

"垃圾围城",是当今城市发展进程中面临的一道坎。据报道,全国现有2/3的大中城市正遭遇"垃圾围城"之困,1/4的城市已无处可堆垃圾。为了破解"垃圾围城"之困,杭州市人大常委会展开了持续有力的监督。杭州主城区日产垃圾2000余吨,并始终保持高位增长态势,2010年主城区垃圾增长率达10.2%;杭州59%的垃圾仍使用填埋方式处置,每6年的垃圾就能填满一个西湖;作为杭州最主要的垃圾填埋场,天子岭的使用寿命仅剩8年,一旦其丧失填埋功能,

What’s in an MSW? Graduate education for public child welfare workers,intention, engagement,and work environment

ABSTRACT

This study employs a mixed methods analysis of exit survey data gathered from public child welfare employees at their completion of a Title IV-E funded MSW program, distinct because it was initiated during a period of major reform and permitted students to continue employment during their studies. Findings suggest that opportunities for growth and manageable levels of stress were associated with intentions to stay and engagement with the work, reflected in respondents’ positive perceptions of their roles in the work environment and their retrospective assessments of the impact of their social work education.

An effective pedagogy for child welfare education

ABSTRACT

Preparing social workers for child welfare practice with the complexly traumatized children now in the system has created the need for schools of social work to integrate trauma content into the curriculum. This article presents findings of an evaluation of a child welfare course designed to prepare MSW level trauma-informed child welfare practitioners. Findings indicate that students in 29 schools of social work not only significantly increased their confidence in working with traumatized children and families but also are significantly more prepared to work toward these three child welfare goals of safety, permanency, and well-being.

How Does Professional Education Impact the Job Outlook of Public Child Welfare Workers?

Abstract

The objective of this study was to examine how public child welfare employees perceive their graduate social work education, whether they use the knowledge and skills gained, their work satisfaction, and their future plans. It was designed to examine the experiences of the New York City Administration on Children's Services (ACS) employees who were participants in the Professional Development Program and received support to study for their master's degrees in social work. The total number of respondents surveyed was 153, the vast majority of whom were people of color. In considering their motives for attending graduate school, 96 percent emphasized their desire to serve children and families better. These graduates were very positive about their academic and field experiences, with almost all saying they would recommend MSW training to others. There was a constant progression in their perceived knowledge and skill level over time. They expressed a mid-level of satisfaction with their current jobs, but higher satisfaction with the nature of the work itself. It was striking to note the respondents' attitudes about remaining employed at ACS. Only 13 percent of those who responded said they planned to leave within the next two years Almost a third (32.6%) said they thought they'd stay at least 5-9 years, and 39.8 percent said they would probably stay 10 years or longer. Satisfaction with the nature of the work and pay were the two strongest predictors of the length of time respondents planned to stay at ACS. These are important findings because they demonstrate that public investment in MSW education can have significant pay-off by increasing the knowledge and skills of public child welfare workers and encouraging long-term commitment to the work.     

Assessing engagement skills in public child welfare using OSCE: a pilot study

A two-station (scenario) Objective Structured Clinical Examination (OSCE) was developed and tested for validity and reliability for assessing social work engagement skills in public child welfare. The simulated scenario was designed to allow for demonstration of skill with an involuntary adolescent and parent presenting as resistant. Independent raters assessed participants comprised of BSW students, MSW students, and experienced public child protection social workers (n = 17, station one, n = 16 station two). Scales demonstrated high internal consistency, inter-rater reliability, and initial discriminate groups validity. Findings suggest a promising approach for directly assessing social worker skill in engagement of clients. Implications for use of OSCE in child welfare are discussed.
