Does shame influence nonsuicidal self-injury among college students? An investigation into the role of shame,negative urgency,and brooding

College students experience high levels of life stress that put them at increased risk for nonsuicidal self-injury (NSSI). It is important to understand which vulnerabilities put students most at risk, in order to inform treatment in college counseling centers. This study investigated the joint contributions of specific vulnerabilities to lifetime history and frequency of NSSI among a sample of undergraduates (50% reported a history of NSSI). Results showed shame-proneness was uniquely associated with NSSI frequency beyond other negative emotions. Negative urgency and brooding exacerbated this effect. This study provides insights into the contributions of specific vulnerabilities to NSSI and implications for practice.     

Investigating advanced professional learning of early career and experienced teachers through program portfolios

Since closing the gap between different levels of professional development for teachers has been identified as a particular need in our profession, capturing the results of professional coursework can help teacher educators better understand and meet the unique needs of teachers with different levels of experience. This study examined the effects of professional development on early career (EC) and experienced (EXP) teachers during an advanced master’s degree programme in the USA. Qualitative analysis of 47 teacher portfolio reflections and 11 post-programme interviews investigated how EC and EXP teachers engaged in programme learning experiences to determine the ways that coursework influenced their professional growth. Differences between EC and EXP teachers were noteworthy, indicating that these two groups responded to professional development experiences differently. Ongoing research to determine effective differentiated approaches toward professional development for both novice and EXP teachers remains a key area for teacher education research, most particularly with a goal of measuring the results of professional development on improving PK-12 student performance.     

Applications of Multilevel IRT Modeling

The recent development of multilevel IRT models (Fox & Glas, 2001, 2003) has been shown to be very useful for analyzing relationships between observed variables on different levels containing measurement error. Model parameter estimates and their standard deviations are concurrently estimated taking account of measurement error in observed variables. The multilevel IRT models are, in particular, useful in the analysis of school effectiveness research data since hierarchical structured educational data are subject to error. By re-examining some school effectiveness studies, the basic aspects of this new model and consequences of measurement error are shown.     

Constructivism Examined

In this paper I examine constructivism as a view of learning which has come to dominate educational debates about learning in the field of teacher education. The major claims of a variety of constructivist theories are considered and found to be largely wanting, in that they either differ little from common sense empiricist views, or else provide misleading and incomplete views of human learning, with consequently misleading implications for teaching in classrooms.     

Social media use by government: From the routine to the critical

Social media and online services with user-generated content (e.g., Twitter, Facebook, Flickr, YouTube) have made a staggering amount of information (and misinformation) available. Government officials seek to leverage these resources to improve services and communication with citizens. Significant potential exists to identify issues in real time, so emergency managers can monitor and respond to issues concerning public safety. Yet, the sheer volume of social data streams generates substantial noise that must be filtered in order to detect meaningful patterns and trends. Important events can then be identified as spikes in activity, while event meaning and consequences can be deciphered by tracking changes in content and public sentiment. This paper presents findings from a exploratory study we conducted between June and December 2010 with government officials in Arlington, VA (and the greater National Capitol Region around Washington, D.C.), with the broad goal of understanding social media use by government officials as well as community organizations, businesses, and the public at large. A key objective was also to understand social media use specifically for managing crisis situations from the routine (e.g., traffic, weather crises) to the critical (e.g., earthquakes, floods).
