Latent print examiners each completed 60 comparisons using one of the two scales, and the resulting data were modeled using signal detection theory to measure whether the expanded scale changed the threshold for an "Identification" conclusion. When using the expanded scale, examiners became more risk-averse when making "Identification" decisions and tended to transition both the weaker Identification and stronger Inconclusive responses to the "Support for Common Source" statement. The results demonstrate the utility of an expanded conclusion scale and also provide guidance for the adoption of these or similar scales. © 2020 American Academy of Forensic Sciences.Previous studies focusing on the effects of the social aspects of community have often used the Sense of Community Index (SCI), despite other research showing that it is not a good-fit measure for its expected dimensions. Using a sample of students from Brigham Young University, we performed confirmatory factor analysis of the SCI to assess 1-factor, 4-factor, 1-factor revised, 3-factor revised, 1-factor revised, 4-factor revised, and 1-factor revised models. Our study resulted in mixed findings models were neither a poor-fit nor a good fit. Although the 4-factor revised model was the best fit, it did not measure the intended dimensions well. Our analysis indicates that future research investigating sense of community should use measures other than the SCI. © 2020 Wiley Periodicals, Inc.This study aims to analyze the processes of resilience and empowerment experienced by refugees in southern Spain during their participation in a community-based intervention. Intervention design covered two phases over 15 weeks (a) accompanying a group of 10 settled refugees to become mentors, making use of a peer-support-group format; and (b) holding four cultural peer-support groups made up of newly arrived refugees led by the previously trained settled refugees, following a peer-mentoring format. We analyzed the mentors' narratives and written evaluations produced over the course of the intervention program. Mentor resilience increased during the first program phase and remained high and stable during the second phase. Mentor empowerment steadily increased throughout the duration of the program, and was fueled when participants became mentors to newly arrived refugees during the second phase. This study highlights how a peer-support and peer-mentoring approach is useful for enhancing the resilience and empowerment of refugees in receiving societies. © 2020 Wiley Periodicals, Inc.As the closed-circuit television (CCTV) security industry transitioned from analog media to digital video recorders (DVRs) with digital storage, the law enforcement community struggled with the means with which to collect the recordings. New guidelines needed to be established to determine the collection method which would be efficient as well as provide the best quality evidence from live DVRs. A test design was developed to measure, quantify, and rank the quality of acquisition methods used on live systems from DVRs typically used in digital CCTV systems. The purpose was to determine guidelines for acquiring the best quality video for investigative purposes. A test pattern which provided multiple quantifiable metrics for comparison between the methods of acquisition was used. The methods of acquisition included direct data download of the proprietary file and open file format as well as recording the video playback from the DVR via the available display monitor connections including the composite video, Video Graphics Array (VGA), and high-definition multimedia interface (HDMI). While some acquisition methods may provide the best quality evidence, other methods of acquisition are not to be discounted depending on the situation and need for efficiency. As an investigator that needs to retrieve video evidence from live digital CCTV systems, the proprietary file format, overall, provides the best quality evidence. However, depending on the circumstance and as recording technology continues to evolve, options other than the proprietary file format may provide quality that is equal to or greater than the proprietary file format.

Prey populations may also be affected by interactions between multiple predators across life stages of the prey, and by environmental factors such as disturbance. However, the intersection of these multiple drivers of prey dynamics has yet to be empirically evaluated. We addressed this knowledge gap using eastern oysters (Crassostrea virginica), a species known to suffer NCEs, as the focal prey. Over four months, we manipulated orthogonally the life stage (none, juvenile, adult, or both) at which oysters experienced simulated predation (CE) and exposure to olfactory cues of a juvenile oyster predator (crab), adult predator (conch), sequentially the crab and then the conch, or none. We replicated this experiment at three sites along an environmental gradient in a Florida (USA) estuary. For both juvenile and adult oysters, survival was reduced solely by CEs, and variation in growth was best explained by among-site variation in water flow, with a much smaller and negative effect of predator cue. Adults exposed to conch cue exhibited reduced growth (an NCE), but this effect was outweighed by a positive CE on growth surviving oysters grew faster at lower densities. Finally, conch cue reduced larval settlement (another NCE), but this was swamped by among-site variation in larval supply. This research highlights how strong environmental gradients and predator CEs may outweigh the influence of NCEs, even in prey known to respond to predator cues. These findings serve as a cautionary tale for the importance of evaluating NCE processes over temporal scales and across environmental gradients relevant to prey demography.
