A forensic report is the primary work product of a forensic psychologist. The aim of a forensic report is to inform and influence the court. Unlike a clinical report, a forensic report influences the outcome of a legal conflict. This means that greater care must be taken in writing the report. The following errors (Grisso, 2010) were used to discuss best practices in forensic report writing: failure to answer the referral question, organization problems, language problems, mixed data and interpretation, inclusion of irrelevant data, over-reliance on a single source of data, improper psychological test use, failure to consider alternative hypotheses, and opinions without sufficient explanation. The purpose of this paper is to provide in one place all the information needed to improve forensic report writing, and to help the reader apply the literature using specific examples. Redacted report samples were collected from psychologists, graduate psychology trainees, teaching assistant experience, and clinical work. Identified errors in these samples were then corrected using the recommendations in the literature. Geared toward graduate psychology trainees, each section should serve both as a tutorial and as a brief checklist to help the reader avoid common pitfalls and assist in promoting better forensic report writing.

This paper provides a preliminary exploration of the application of Acceptance and Commitment Therapy (ACT) within the context of a forensic hospital. ACT has a reputation for being a clinically flexible and empirically sound therapeutic intervention, which appears uniquely suited for forensic hospital settings. However, no research has been published to date on the use of ACT as a treatment for forensic inpatients. The ACT approach directly aims to help people let go of the unwinnable struggles to control symptoms of mental illness, and instead focus on constructing a "life worth living." ACT interventions can equip forensic patients with the values and flexible behavioral repertoires necessary to lead lives that are personally meaningful and satisfying and do not involve inflicting harm to others. The ACT model also attempts to minimize the therapist-patient hierarchy through an emphasis on the ubiquitous nature of human suffering. This approach can be particularly useful when working with marginalized, treatment-resistant patients. Continued research on the application of ACT with forensic inpatients is recommended.

Challenges in treating children with an autism spectrum disorder (ASD) in medical settings are identified and discussed. Although research supports interventions for children with ASD including positive reinforcement, environmental modification, and visual supports and systems, limited research on the efficacy of these interventions in medical environments and with specific procedures exists. Based on the available intervention literature, this project proposes a picture schedule reinforcement system for use during blood draw procedures for ASD children with diabetes. Future efforts should include increased education for medical providers and health professionals as psychological interventions continue to inform best practices in care for children with ASD in medical settings.

Between 30% and 90% of the prison population is estimated to have survived traumatic experiences such as sexual, emotional, and physical abuse prior to incarceration (Anonymous, 1999; Fondacaro, Holt, & Powell, 1999; Messina & Grella, 2006; Pollard & Baker, 2000; Veysey, De Cou, & Prescott, 1998). Similarly, information from the Bureau of Justice Statistics (as reported in Warren, 2001) estimated that more than half of the women in state prisons have experienced past physical and sexual abuse. Thus, given the astonishing number of inmates who appear to be victims of some kind of trauma, it seems likely that those who work with these inmates (e.g., prison staff, guards, and treatment providers) will in some way encounter challenges related to the inmates' trauma history. These difficulties may appear in any number of forms including inmates' behavioral outbursts, increased emotionality, sensitivity to triggering situations, and chronic physical or mental health needs (Veysey, et al., 1998). It is also likely that these individuals with trauma histories would benefit greatly from treatment while incarcerated. This treatment could be utilized to minimize symptoms of posttraumatic stress, decrease behavioral problems, and help the inmate function more effectively in society when released from incarceration (Kokorowski & Freng, 2001; Tucker, Cosio, Meshreki, 2003). Few studies have explored the types of trauma treatment that are effective with inmate populations or made specific suggestions for clinicians working in forensic settings (Kokorowski & Freng, 2001). Essentially, there appears to be a large gap in terms of the need for trauma treatment for inmates and the lack of literature addressing what to do about it. However, clinicians across the country seem to be quietly attempting to fulfill this need for trauma treatment with incarcerated populations. They are providing this greatly needed treatment every day. in the face of enormous challenges and often without recognition or the opportunity to share their valuable work with the larger community.

Therapeutic Assessment is a semi-structured approach to collaborative assessment developed by Stephen E. Finn and colleagues. In Therapeutic Assessment, psychological assessment is used as a therapeutic intervention (Finn, 2007; Finn & Kamphuis, 2006). The Therapeutic Assessment model differs from traditional assessment with regard to procedure and the roles of both assessor and client. Therapeutic Assessment has yet to be explored in forensic settings, wherein assessors are required to take on a number of varying and conflicting roles. In the current study, five forensic psychologists completed a semi-structured interview to identify their perspectives of Therapeutic Assessment and its utility in forensic contexts. A phenomenological qualitative analysis of the interviews was conducted to derive themes about Therapeutic Assessment, forensic psychology, and the overlap between these two domains. General themes that emerged include (a) the role and the context of the practitioner's work with the forensic population; (b) the potential of using Therapeutic Assessment's paradigm in family law settings; and (c) the increased risk of harm when using Therapeutic Assessment with forensic populations. In addition to these themes, multiple respondents discussed components of collaborative/Therapeutic Assessment that they have found useful with this population. Finally, the implications of these results are discussed.

While working in clinical and forensic psychology settings, a communication difficulty between the two professions became apparent. Forensic psychologists often appeared cold and callous from the clinical psychologist’s perspective, while clinical psychologists often appeared naïve or too client centered from the forensic psychologist’s perspective. I wondered if viewing each subfield of psychology as a culture could facilitate better communication through intercultural communication. Guided by Intercultural Communication in Contexts (Martin & Nakayama, 2010) in approaching intercultural communication between the two professions, I explored factors contributing to each profession’s cultural identities. Once this was established, I attempted to explore the different ways each culture could communicate more effectively. By recognizing and utilizing the strengths from each profession and understanding the possible pitfalls of one’s own, we may become competent in intercultural communication

This dissertation introduces an approach to generate tests to test fail-safe behavior for web applications. We apply the approach to a commercial web application. We build models for both behavioral and mitigation requirements. We create mitigation tests from an existing functional black box test suite by determining failure type and points of failure in the test suite and weaving required mitigation based on weaving rules to generate a test suite that tests proper mitigation of failures. A genetic algorithm (GA) is used to determine points of failure and type of failure that needs to be tested. Mitigation test paths are woven into the behavioral test at the point of failure based on failure specific weaving rules. A simulator was developed to evaluate choice of parameters for the genetic algorithm. We showed how to tune the fitness function and performed tuning experiments for GA to determine what values to use for exploration weight and prospecting weight. We found that higher defect densities make prospecting and mining more successful, while lower mitigation defect densities need more exploration. We compare efficiency and effectiveness of the approach. First, the GA approach is compared to random selection. The results show that the GA performance was better than random selection and that the approach was robust when the search space increased. Second, we compare the GA against four coverage criteria. The results of comparison show that test requirements generated by a genetic algorithm (GA) are more efficient than three of the four coverage criteria for large search spaces. They are equally effective. For small search spaces, the genetic algorithm is less effective than three of the four coverage criteria. The fourth coverage criteria is too weak and unable to find all defects in almost all cases. We also present a large case study of a mortgage system at one of our industrial partners and show how we formalize the approach. We evaluate the use of a GA to create test requirements. The evaluation includes choice of initial population, multiplicity of runs and a discussion of the cost of evaluating fitness. Finally, we build a selective regression testing approach based on types of changes (add, delete, or modify) that could occur in the behavioral model, the fault model, the mitigation models, the weaving rules, and the state-event matrix. We provide a systematic method by showing the formalization steps for each type of change to the various models.

The Colorado Alliance of Research Libraries has launched the Alliance Shared Print Trust and is in the process of developing a shared print analysis tool. The system allows libraries to compare themselves with other libraries that have added their MARC records so that they can easily and quickly determine what records are unique or held in common with other libraries. The comparison system is built on open source tools and has been embedded in the Gold Rush framework. The author provides a brief overview of other shared print analysis tools.

The Journal Retention and Needs Listing (JRNL) program: 1) allows libraries to expose lists of print journals for which they have made retention commitments; 2) express needs (or gaps) in their holdings; and 3) communicate offers to fill the gaps in other participating libraries’ holdings. Multiple library consortia and their member libraries use JRNL to facilitate communication between library staff to identify holding commitments, fill gaps, and guide deselection decisions. JRNL is commonly developed and governed by the participating consortia. Currently, those consortia are the Florida Academic Repository (FLARE), the Association of Southeastern Research Libraries (ASERL)/Washington Research Library Consortium (WRLC), and the Western Regional Storage Trust (WEST).

This paper discusses the impact of machine translation on the language industry, specifically addressing its effect on translators. It summarizes the history of the development of machine translation, explains the underlying theory that ties machine translation to its practical applications, and describes the different types of machine translation as well as other tools familiar to translators. There are arguments for and against its use, as well as evaluation methods for testing it. Internet and real-time communication are featured for their role in the increase of machine translation use. The potential that this technology has in the future of professional translation is examined. This paper shows that machine translation will continue to be increasingly used whether translators like it or not.
