Research about the attitudes and beliefs of correctional officers has historically been conducted in prison facilities while ignoring jail settings. This study contributes to our understanding of correctional officers by examining the perceptions of those who work in jails, specifically measuring professional orientations about counseling roles, punitiveness, corruption of authority by inmates, and social distance from inmates. The study also examines whether officers are accurate in estimating these same perceptions of their peers, a line of inquiry that has been relatively ignored. Findings indicate that the sample was concerned about various aspects of their job and the management of inmates. Specifically, officers were uncertain about adopting counseling roles, were somewhat punitive, and were concerned both with maintaining social distance from inmates and with an inmate's ability to corrupt their authority. Officers also misperceived the professional orientation of their fellow officers and assumed their peer group to be less progressive than they actually were. © The Author(s) 2013. Source

Aggression and Violent Behavior | Year: 2014

Despite broad consensus regarding the value of the impulsive/premeditated and reactive/proactive aggression classifications, confusion as a result of imprecise language and the exact nature of subtypes have threatened its utility for clinical and research purposes. In order to increase the usefulness of these subtypes in research, prevention, and treatment, the current review examines whether differences in these two subtype classifications are theoretical, semantic or empirical. Correlates of impulsive, premeditated, reactive, or proactive aggression measures were examined for consistency. Based on the different conceptual roots, we expected that each subtype pair would evidence only partial correspondence such that the classification systems may actually be capturing different constructs. The findings of a targeted and selective review suggest there is more correspondence between reactive and impulsive aggression than there is between proactive and premeditated aggression. An agenda for future research is outlined. © 2014 Elsevier Ltd. Source

Classifying land cover via satellite imagery is an important problem in geographical studies. This paper presents a maximum a posteriori (MAP) land-cover classifier for multiband satellite data. The method uses the Markov random field model. The MAP estimation is carried out via iterated conditional modes. The reflectivities are transformed via principal components to overcome correlation and skewness, and then the distributions of the components are estimated with kernel densities. To make use of a large amount of past work in the area, the prior distribution is selected from the US Geological Survey's land-cover database. Prior hyperparameters are estimated by equating some of their differences with the logarithms of ratios of relative frequencies from the land-cover survey, and then estimated via least squares and a bagging-type procedure. The resulting classifier produces a smooth image and captures detailed features of the study area, including roads. © 2012 Elsevier B.V. All rights reserved. Source

Policy to address the shifting tree species distributions anticipated in coming decades requires a sound understanding of how forests respond to environmental change. Using a combination of remote sensing, geographic information systems (GIS) analysis, and ground-based techniques, we explored the environmental factors associated with the distribution and abundance of trembling aspen (Populus tremuloides Michx.) across regional gradients near its northern range limit in northwestern Quebec, Canada. Although not regionally abundant, aspen is the main deciduous tree species in this conifer-dominated landscape. Regionally, the 51,200-km2 study area has very few settlements or roads, and little industrial resource extraction. Most of the region is inaccessible to humans except by foot or water travel. We utilized Landsat Thematic Mapper images from 2010 and 2011, and a robust collection of ground reference data developed from aerial photography, supported by field verification (vegetation sampling) where access permitted, to construct a thematic map of 11 land cover classes. The map highlights the spatial distribution of aspen, which represents only 0.3% of the study area. Map validation indicated an overall mapping accuracy of 74%, and the aspen predicted class was determined to be over 77% accurate. The regional-scale distribution of aspen stands ≥0.5 ha within the study area shows two patterns: (1) a shift toward greatest abundance on south-facing aspects with increasing latitude; and (2) a highly clustered pattern with a strong signal of concentration in areas of human activity. These patterns suggest that aspen range expansion due to climate warming will vary with topographic and other microclimatic factors (i.e. be a function of climate change interacting with landscapes) and that anthropogenic activities have the potential to influence future aspen abundance independently of climate. Forest management policies concerned with changing forest composition in these northern landscapes should recognize the potentially important role of human activity in driving the abundance of aspen. © 2016.Published by Elsevier B.V.

Cyberpsychology, Behavior, and Social Networking | Year: 2012

The current study was designed to extend the interpersonal deviance literature into the online domain by examining the incidence and impact of supervisor cyber incivility and neuroticism on employee outcomes at work. Conservation of Resources (COR) theory was used as the guiding framework because cyber incivility is thought to deplete energetic resources in much the same way that other stressors do, ultimately leading to negative outcomes like burnout. Results indicate that supervisor cyber incivility is positively related to burnout, absenteeism, and turnover intentions. Support was also found for the role of neuroticism as a moderator of the relationship between supervisor cyber incivility and outcomes. In general, the relations between cyber incivility and outcomes were stronger for those individuals reporting higher levels of neuroticism. Results are discussed in terms of COR theory, and possible mechanisms for the role of neuroticism in the stressor-strain relationship are discussed. The current study highlights the importance of understanding workplace online behavior and its impact on employee health and organizational well-being. Future research directions examining online interpersonal deviance are suggested. © 2012, Mary Ann Liebert, Inc. Source
