Contour integration is a fundamental visual process that recovers object structure by representing spatially separated edge elements as a continuous contour or shape boundary. Clinically stable persons with schizophrenia have repeatedly been shown to be impaired at contour integration but it is unclear whether this process varies with clinical state or whether it arises as early as the first episode of psychosis. To consider these issues, we administered a contour integration test to persons with chronic schizophrenia and to those with a first episode of psychosis. The test was administered twice-once at admission to short term psychiatric hospitalization and once again at discharge. A well-matched healthy control group was also tested across the same time points. We found that contour integration performance improved to the same degree in all groups over time, indicating that there were no recovery effects over and above normal practice effects. Moreover, the schizophrenia group demonstrated poorer contour integration than the control group and the first episode group exhibited intermediate performance that could not be distinguished from the other groups. These results suggest that contour integration ability does not vary as a function of short-term changes in clinical state, and that it may become further impaired with an increased number of psychotic episodes. © 2014 Elsevier B.V.

This research investigates how individuals who reenter society from prison use coping strategies. Participants are incarcerated individuals who recidivated following a previous release from prison (n = 20). Participants examine their most recent reentry experience via an interview. The research question under investigation is, "What themes describe how individuals cope with reentry from prison to society?" Data and results combine qualitative and quantitative analysis methods. The predominant coping strategy for dealing with reentry barriers is avoidance. There is a defined process experienced by participants, which is initial optimism about release, followed by craving substances, facing practical barriers, and/or feeling overwhelmed. This eventually results in avoidance of managing problems and emotions and substance abuse relapse, which culminates in recidivism. © 2011 SAGE Publications.

The current study examined viewers' gaze while observing Facebook profiles of strangers varying in gender and physical attractiveness. Fifty-one participants viewed four Facebook profiles, a physically attractive and unattractive individual of each gender. Participants' eye movements were tracked as they viewed each profile for 60 seconds. Results showed that participants paid more attention to the physical appearance (main profile photograph) of female than of male profile owners and to the personal information (likes and interests) of male than to female profile owners. Participants spent more time focusing on information that was irrelevant to forming an impression of the profile owner (advertisements) when viewing the profiles of unattractive than attractive individuals, suggesting that they made a greater effort to learn about these individuals. © Mary Ann Liebert, Inc.

To test the effect of varying the proton donor-acceptor distance in proton-coupled electron transfer (PCET) reactions, the oxidation of a bicyclic amino-indanol (2) is compared with that of a closely related phenol with an ortho CPh 2NH 2 substituent (1). Spectroscopic, structural, thermochemical, and computational studies show that the two amino-phenols are very similar, except that the O⋯N distance (d ON) is >0.1 Å longer in 2 than in 1. The difference in d ON is 0.13 ± 0.03 Å from X-ray crystallography and 0.165 Å from DFT calculations. Oxidations of these phenols by outer-sphere oxidants yield distonic radical cations •OAr-NH 3 + by concerted proton-electron transfer (CPET). Simple tunneling and classical kinetic models both predict that the longer donor-acceptor distance in 2 should lead to slower reactions, by ca. 2 orders of magnitude, as well as larger H/D kinetic isotope effects (KIEs). However, kinetic studies show that the compound with the longer proton-transfer distance, 2, exhibits smaller KIEs and has rate constants that are quite close to those of 1. For example, the oxidation of 2 by the triarylamminium radical cation N(C 6H 4OMe) 3 •+ (3a +) occurs at (1.4 ± 0.1) × 10 4 M -1 s -1, only a factor of 2 slower than the closely related reaction of 1 with N(C 6H 4OMe) 2(C 6H 4Br) •+ (3b +). This difference in rate constants is well accounted for by the slightly different free energies of reaction: ΔG° (2 + 3a +) = +0.078 V versus ΔG° (1 + 3b +) = +0.04 V. The two phenol-amines do display some subtle kinetic differences: for instance, compound 2 has a shallower dependence of CPET rate constants on driving force (Brønsted α, Δ ln(k)/Δ ln(K eq)). These results show that the simple tunneling model is not a good predictor of the effect of proton donor-acceptor distance on concerted-electron transfer reactions involving strongly hydrogen-bonded systems. Computational analysis of the observed similarity of the two phenols emphasizes the importance of the highly anharmonic O⋯H⋯N potential energy surface and the influence of proton vibrational excited states. © 2011 American Chemical Society.

Journal of Substance Use | Year: 2013
This study expanded on past research on perception of individuals by comparing people who are described as using substances with people who are described as smoking and people who are described as obese. This research was a 2 (active difficulty vs. remission) by 3 (substance use, smoking, obesity) factorial design. There were a total of N = 161 adult participants who read a fictitious scenario about an individual who was either actively facing one of the aforementioned problems or in remission. Participants then answered questions that measured reported desired social distance from the individual in the scenario. As hypothesized, people who were actively using substances were the most highly stigmatized group, receiving a high level of reported intention to be socially distant from the individual. Implications of these findings for treatment of individuals who are using substances and training of treatment professionals are addressed. © 2013 Informa UK Ltd.

Benthic macroinvertebrate abundance, taxonomic composition, and surface flooding dynamics were compared among high and low elevation stands of narrow-leaved cattail (Typha angustifolia) and invasive common reed (Phragmites australis) at Iona Island Marsh, an oligohaline wetland, and Piermont Marsh, a mesohaline wetland, within the Hudson River National Estuarine Research Reserve during 1999 and 2000. Overall, the benthic macroinvertebrate community at both sites was similar in composition and abundance to those documented from other low-salinity systems. Macroinvertebrate taxa richness was lowest in mesohaline common reed, but similar among common reed and cattail habitats in oligohaline wetlands. Total macroinvertebrate densities were greater at high-elevation compared to low-elevation reed stands at the mesohaline site during summer 1999 and spring 2000. Total macroinvertebrate densities were similar among both oligohaline vegetation types during all seasons, except for spring 2000, when lower densities were observed in low-elevation common reed. A weak positive relationship between macroinvertebrate density and depth of flooding suggests that surface hydrology may be influencing the observed patterns of macroinvertebrate density among the vegetation stands. These results suggest that benthic macroinvertebrate abundance and diversity may not necessarily be impaired in low-salinity wetlands experiencing invasion by common reed unless the change in vegetation is accompanied by a measurable alteration to physical conditions on the marsh surface (i. e., elevation and flooding dynamics). © 2012 Coastal and Estuarine Research Federation.

The present research examined correlates of "true self" expression to offline friends on Facebook. The "true self" (McKenna et al., 2002) consists of qualities an individual currently possesses but does not normally express to others. In Study 1, 184 undergraduates completed an online survey assessing "true self" expression to their friends online and reported the frequency of various Facebook activities. True self expression was positively correlated with using Facebook for communicating with others, general self-disclosure, emotional disclosure, attention-seeking, and acceptance-seeking, but was unrelated to seeking connection with and expressing caring for others. In Study 2, 41 undergraduates completed the "true self" measure and their Facebook profiles were saved and coded. True self expression was positively correlated with frequency of posting on others' walls, but not posting on one's own wall or receiving posts from others. Finally, true self expression was positively associated with the level of personal disclosure of participants' wall posts. These results suggest that those who feel able to express their "true self" online are more active on Facebook, have more self-oriented motivations for posting, and post more personally revealing and emotional content. © 2013 Elsevier Ltd.

This paper examines the factors influencing school districts' participation in the voluntary open enrollment program in Massachusetts. It investigates whether school districts engage in strategic interaction when making the participation decision. The motivation for testing the strategic interaction hypothesis is to determine whether the driving force behind the participation decision of a district is the competition from neighboring districts, with a potential threat of taking away students and funding. The discrete choice participation decision is modeled using a Bayesian spatial probit model. The results suggest that a given district's probability of participation is positively affected by the participation decisions of its neighbors and this provides strong evidence of horizontal interaction in school choice policies. © 2011 Springer-Verlag.

The S-STEM Program at Albright College supports students to overcome challenges that typically cause undergraduates to leave the STEM fields. The S-STEM support is used to increase recruitment and retention of talented students who may otherwise not be able to afford college. Special attention is made to promote high-quality STEM education opportunities to talented, low-income and minority students. To accomplish this, early interventions for students include increased tutoring availability, cohort-focused academic activities, and optional research internship programs. Encouragement of diversity in the STEM workforce is facilitated through professional development opportunities for STEM students.
The technical features of this project centers on the appreciation of the multiple contributions STEM fields make towards the study of the environment. This S-STEM Program is capitalizing on prior progress made in environmentally-oriented science curriculum at Albright College. In this S-STEM Program, environmental science is the primary method used to increase the visibility of the STEM fields. Across campus at Albright College, students are recruited into the program from varied educational backgrounds. Students are involved with projects that benefit the campus and greater community through various class projects and learning experiences. Notable project implementation components include improved student support services that lead to student success in the classroom and their future career paths.
