Linking Crimes Using Behavioural Clues: Current Levels of Linking Accuracy and Strategies for Moving Forward

The number of published studies examining crime linkage analysis has grown rapidly over the last decade, to the point where a special issue of this journal has recently been dedicated to the topic. Many of these studies have used a particular measure (the area under the receiver operating characteristic curve, or the AUC) to quantify the degree to which it is possible to link crimes. This article reviews studies that have utilised the AUC and examines how good we are currently at linking crimes (within the context of these research studies) and what factors impact linking accuracy. The results of the review suggest that, in the majority of cases, moderate levels of linking accuracy are achieved. Of the various factors that have been examined that might impact linking accuracy, the three factors that appear to have the most significant impact are crime type, behavioural domain, and jurisdiction. We discuss how generalisable these results are to naturalistic investigative settings. We also highlight some of the important limitations of the linking studies that we reviewed and offer up some strategies for moving this area of research forward.

Positive Psychology and Attachment: Positive Affect as a Mediator of Developmental Outcomes

Fredrickson’s (1998) broaden-and-build model and Bowlby’s (1969) attachment theory provide alternate explanations for positive cognitive, social, physical, and psychological outcomes, positive affect and secure attachments, respectively. This study examined whether affect mediates the relationship between attachment and positive outcomes. The sample consisted of 99 undergraduate students from a small, public liberal arts college in the mid-Atlantic region. For people high in attachment anxiety, but not those high in attachment avoidance, affect partially mediated social and psychological outcomes and fully mediated health outcomes. People who scored high in attachment anxiety reported less positive affect and more negative affect, which results in poorer social, physical, and psychological outcomes than those with lower levels of attachment anxiety. Perhaps children with caregivers who are more responsive to their needs experience more positive affect; and, it is the experience of positive affect that yields developmental advantages.     

Micro-breaks matter: A diary study on the effects of energy management strategies on occupational well-being

Organizational researchers and practitioners are increasingly interested in self-regulatory strategies employees can use at work to sustain or improve their occupational well-being. A recent cross-sectional study on energy management strategies suggested that many work-related strategies (e.g., setting a new goal) are positively related to occupational well-being, whereas many micro-breaks (e.g., listening to music) are negatively related to occupational well-being. We used a diary study design to take a closer look at the effects of these energy management strategies on fatigue and vitality. Based on conservation of resources theory, we hypothesized that both types of energy management strategies negatively predict fatigue and positively predict vitality. Employees (N = 124) responded to a baseline survey and to hourly surveys across one work day (6.7 times on average). Consistent with previous research, between-person differences in the use of work-related strategies were positively associated with between-person differences in vitality. However, results of multilevel analyses of the hourly diary data showed that only micro-breaks negatively predicted fatigue and positively predicted vitality. These findings suggest that taking micro-breaks during the work day may have short-term effects on occupational well-being, whereas using work-related strategies may have long-term effects.     

“Leaving it to God” Religion and Spirituality among Filipina Immigrant Breast Cancer Survivors

Many Filipinos have a powerful adherence to Catholicism. However, little is known about spirituality and religious involvement of Filipina Americans who have been diagnosed with breast cancer. Ten (n = 10) in-depth qualitative interviews with Filipina immigrant breast cancer survivors identified prayer to be the most common religious practice, followed by prayers by others and spiritual support from the Catholic Church. These findings can help clinicians and researchers understand the role of spirituality and religion in providing comfort and support for Filipina immigrant breast cancer patient as they face the stress of diagnosis and treatment.     

The Emergence of Clinical Research Ethics Consultation: Insights From a National Collaborative

The increasing complexity of human subjects research and its oversight has prompted researchers, as well as institutional review boards (IRBs), to have a forum in which to discuss challenging or novel ethical issues not fully addressed by regulations. Research ethics consultation (REC) services provide such a forum. In this article, we rely on the experiences of a national Research Ethics Consultation Collaborative that collected more than 350 research ethics consultations in a repository and published 18 challenging cases with accompanying ethical commentaries to highlight four contexts in which REC can be a valuable resource. REC assists: 1) investigators before and after the regulatory review; 2) investigators, IRBs, and other research administrators facing challenging and novel ethical issues; 3) IRBs and investigators with the increasing challenges of informed consent and risk/benefit analysis; and 4) in providing flexible and collaborative assistance to overcome study hurdles, mediate conflicts within a team, or directly engage with research participants. Institutions that have established, or plan to establish, REC services should work to raise the visibility of their service and engage in open communication with existing clinical ethics consult services as well as the IRB. While the IRB system remains the foundation for the ethical review of research, REC can be a valuable service for investigators, regulators, and research participants aligned with the goal of supporting ethical research.     

Statistical properties of four effect-size measures for mediation models

This project examined the performance of classical and Bayesian estimators of four effect size measures for the indirect effect in a single-mediator model and a two-mediator model. Compared to the proportion and ratio mediation effect sizes, standardized mediation effect-size measures were relatively unbiased and efficient in the single-mediator model and the two-mediator model. Percentile and bias-corrected bootstrap interval estimates of ab/s _Y , and ab(s _X )/s _Y in the single-mediator model outperformed interval estimates of the proportion and ratio effect sizes in terms of power, Type I error rate, coverage, imbalance, and interval width. For the two-mediator model, standardized effect-size measures were superior to the proportion and ratio effect-size measures. Furthermore, it was found that Bayesian point and interval summaries of posterior distributions of standardized effect-size measures reduced excessive relative bias for certain parameter combinations. The standardized effect-size measures are the best effect-size measures for quantifying mediated effects.     

RBANS Validity Indices: a Systematic Review and Meta-Analysis

Neuropsychology practice organizations have highlighted the need for thorough evaluation of performance validity as part of the neuropsychological assessment process. Embedded validity indices are derived from existing measures and expand the scope of validity assessment. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a brief instrument that quickly allows a clinician to assess a variety of cognitive domains. The RBANS also contains multiple embedded validity indicators. The purpose of this study was to synthesize the utility of those indicators to assess performance validity. A systematic search was completed, resulting in 11 studies for synthesis and 10 for meta-analysis. Data were synthesized on four indices and three subtests across samples of civilians, service members, and veterans. Sufficient data for meta-analysis were only available for the Effort Index, and related analyses indicated optimal cutoff scores of ≥1 (AUC?=?.86) and?≥?3 (AUC?=?.85). However, outliers and heterogeneity were present indicating the importance of age and evaluation context. Overall, embedded validity indicators have shown adequate diagnostic accuracy across a variety of populations. Recommendations for interpreting these measures and future studies are provided.     

Grammatical gender in the production of single words: some evidence from Greek

The present study investigated the effect of prior grammatical gender information provided by the production of a bare noun on the production of a syntactically unrelated, gender-inflected color adjective. The target language was Greek. A lexical priming task involving picture naming was employed. Participants saw a series of pictures, some in color and some in black-and-white; they had to name a black-and-white picture with the single noun (prime) and a color picture with the appropriately inflected color adjective (target). Prior gender information was shown to affect subsequent production of gender-marked words. The effect was restricted to nouns of one gender class (masculine) only. The implications of these results for the representation and processing of gender in production are discussed.     

The Relationship of Suicidal Ideation to Objective and Subjective Executive Functioning

Prior research on executive ability and suicidal ideation (SI) has frequently failed to account for either symptom or performance validity. Similarly, studies have not adequately examined both objective performance on executive tests and subjective report of executive deficits in relationship to SI. The purpose of this study was to address these gaps in research by accounting for performance validity, symptom validity, and considering self-reported executive complaints with objective performance. We hypothesized that (a) increases in self-reported SI on the Personality Assessment Inventory (PAI; Morey, 1991 Morey, L. C. (1991). Personality Assessment Inventory: Professional manual. Tampa, FL: Psychological Assessment Resources. [Google Scholar]) Suicidal Ideation subscale would be related to poorer performance on objective and subjective tests of executive function and (b) level of self-reported depressive symptoms would moderate the relationship between SI and measures of executive function, such that individuals with higher levels of both depressive symptoms and executive dysfunction would be more likely to experience higher levels of SI. No measure of executive function was related to SI when accounting for demographic variables and depressive symptoms. Wisconsin Card Sort Test categories completed was the only measure of executive function to interact significantly with depressive symptoms to predict SI (β = .43). Of particular note, self-reported executive dysfunction was highly correlated with Beck Depression Inventory?II ( Beck, Steer, &; Brown, 1996 Beck, A. T., Steer, R. A., &; Brown, G. K. (1996). Beck Depression Inventory (2nd ed.). San Antonio, TX: The Psychological Corporation. [Google Scholar]) scores (r = .78). Clinical implications and future directions for research are discussed.
