Semiotic technologies: a case study of discipline-based practices and pedagogy

This paper examines semiotic technologies, both in terms of the resources they harness and the practices developed around their use. It draws on data collected as part of an ethnographic investigation into the meaning-making practices deployed within civil engineering study. The data is used as a case study for examining semiotic technologies as socially situated resources for disciplinary practices. Using a multimodal social semiotic approach, we argue that technologies are not self-evident, and that their use constitutes specific social practices that require development in the classroom. In order to deploy technologies in pedagogically effective ways, we need to understand the semiotic resources they draw on (including embodied resources). Awareness that technologies are not neutral or value-free, but are socially situated and ideologically laden, may enable meta-level understanding of the discipline, thus creating the possibility for improved pedagogical practices.     

Reigniting the fire: a contemporary research agenda for social,political and nonprofit marketing

The paper reports on the core challenges faced by the nonprofit, political and social marketing disciplinary areas and suggests a series of research agendas to develop theory and practice to meet these challenges.

• Social marketing's research agenda involves the continued adaptation of the new developments in commercial marketing, whilst building a base of social marketing theory and best practice benchmarks that can be used to identify, clarify and classify the boundaries of social marketing against social change techniques.
• Nonprofit marketing is pursuing the dual research agenda of developing the theory and practice of social entrepreneurship whilst seeking deeper consumer‐based research to understand motivations for charitable behaviour and gift giving.
• Political Marketing's research agenda looks for an increase in the level of background research, core data and market research to use as a basis for developing more advanced theoretical and practical models. In addition, as political marketing is being transferred internationally between a range of political and electoral systems, there is a need for comparative research into both the relevance and effectiveness of these techniques to isolate nation independent and nation dependent political marketing strategies and campaigns.

Numerical classification of curvilinear structures for the identification of pistol barrels

This paper demonstrates a numerical pattern recognition method applied to curvilinear image structures. These structures are extracted from physical cross-sections of cast internal pistol barrel surfaces. Variations in structure arise from gun design and manufacturing method providing a basis for discrimination and identification. Binarised curvilinear land transition images are processed with fast Fourier transform on which principal component analysis is performed. One-way analysis of variance (95% confidence interval) concludes significant differentiation between 11 barrel manufacturers when calculating weighted Euclidean distance between any trio of land transitions and an average land transition for each barrel in the database. The proposed methodology is therefore a promising novel approach for the classification and identification of firearms.     

Self-protective behaviors and injury in domestic violence situations: does it hurt to fight back?

Research examining the impact of self-protective behaviors on outcomes in nonsexual assaults involving intimates has focused solely on one mainstream sample (National Crime Victimization Survey) in which violence is a relatively rare event. Using the Women's Experience of Violence (WEV) project which collects data from a sample of incarcerated women, we explored the phenomenon of self-protective behaviors to assess whether their use impacts the probability and severity of subsequent injury during a domestic violence incident. In addition to utilizing a unique sample, we considered an alternative operationalization of self-protective behaviors that separates physical and verbal responses to include whether the behavior involved an element of force. Results suggest some similarities between a mainstream sample and our marginalized sample. Namely, the frequency in which they utilize countermeasures and the effect of "fighting back" appear to be consistent with previous research. However, the more nuanced categorization of self-protective behaviors demonstrates the importance of considering whether the strategy was forceful when examining women's responses to violence.     

Having a Bad Month: General Versus Specific Effects of Stress on Crime

We examine whether particular types of stress are related to particular types of crime or whether all types of stress are related to all types of crime. Our estimates are based on analyses of within-individual change over a 36 month period among recently incarcerated offenders. We find that assault is most strongly related to family stress, suggesting that conflicts between family members lead to assault. Economic crimes (property crimes and selling illicit drugs) are most clearly related to financial stress, suggesting that these crimes often reflect attempts to resolve financial problems. On the other hand, crime is generally unrelated to stress from illness/injury, death, and work. The results support the idea that criminal behavior is a focused response to specific types of problems rather than a general response to stress. They are more consistent with explanations that focus on perceived rewards and costs (e.g., the rational-choice approach) than with explanations that portray negative affect as a generalized impetus toward violence or crime (e.g., frustration aggression approaches).     

Texas Christian University (TCU) Short Forms for Assessing Client Needs and Functioning in Addiction Treatment

The TCU Short Forms contain a revised and expanded set of assessments for planning and managing addiction treatment services. They are formatted as brief (1-page) forms to measure client needs and functioning, including drug use severity and history (TCUDS II), criminal thinking and cognitive orientation (CTSForm), motivation and readiness for treatment (MOTForm), psychological functioning (PSYForm), social relations and functioning (SOCForm), and therapeutic participation and engagement (ENGForm). These instruments facilitate optically-scanned data entry, computerized scoring, and rapid graphical feedback for clinical decisions. The present study (based on 5,022 inmates from eight residential prison treatment programs) examines evidence on scale reliabilities and measurement structures of these tools. Results confirmed their integrity and usefulness as indicators of individual and group-level therapeutic dynamics.
