Assessing Ecological and Social Outcomes of a Bear-Proofing Experiment
Human-black bear conflicts within urban environments have been increasing throughout North America, becoming a high priority management issue. The main factor influencing these conflicts is black bears foraging on anthropogenic foods within areas of human development, primarily on residential garbage. Wildlife professionals have advocated for increased bear-proofing measures to decrease the accessibility of garbage to bears, but little research has been conducted to empirically test the effectiveness of this approach for reducing conflicts. Between 2011 and 2016, we conducted a before-after-control-impact experiment in Durango, Colorado where we distributed 1,110 bear-resistant trash containers, enhanced education, and increased enforcement to residents in 2 treatment areas, and monitored 2 paired control areas. We examined the ecological and social outcomes of this experiment, assessing whether bear-resistant containers were effective at reducing conflicts; the level of public compliance (i.e., properly locking away garbage) needed to reduce conflicts; whether the effectiveness of bear-resistant containers increased over time; and if the distribution of bear-resistant containers changed residents’ attitudes about bear management, support for ordinances that require bear-proofing, or perceptions of their future risk of garbage-related conflicts. After the bear-resistant containers were deployed, trash-related conflicts (i.e., observations of strewn trash) were 60% lower in treatment areas than control areas, resident compliance with local wildlife ordinances (properly locking away trash) was 39% higher in treatment areas than control areas, and the effectiveness of the new containers was immediate. Conflicts declined as resident compliance with wildlife ordinances increased to approximately 60% (by using a bear-resistant container or locking trash in a secure location), with minor additional declines in conflicts at higher levels of compliance. In addition to these ecological benefits, public mail surveys demonstrated that the deployment of bear-resistant containers was associated with increases in the perceived quality of bear management and support for ordinances that require bear-proofing, and declines in the perceived risk of future trash-related conflicts. Our results validate efforts by wildlife professionals and municipalities to reduce black bear access to human foods, and should encourage other entities of the merits of bear-proofing efforts for reducing human-bear conflicts and improving public attitudes about bears and their management

A Comparison of Esomeprazole and Lansoprazole for Control of Intragastric pH in Patients With Symptoms of Gastro-Oesophageal Reflux Disease
Background: Intragastric acid suppression is the most direct measure of the pharmacodynamic efficacy of proton pump inhibitors, which are the most effective drugs for acid-related diseases. Aim: To compare the effectiveness of once and twice daily dosing of lansoprazole and esomeprazole in controlling intragastric acidity ( target gastric pH \u3e 4.0) over a 24-hour period. Methods: In an open-label, two-way crossover study, 45 Helicobacter pylori-negative patients with gastro-oesophageal reflux disease were randomized to receive one of two regimens: 30 mg lansoprazole or esomeprazole 40 mg once daily. Intragastric pH was assessed by 24-hour pH monitoring on day 5 of each regimen. Dosing was increased to twice daily and pH was re-assessed on day 10. Following a 14-day washout, patients were crossed over to the other medication and the dosage regimens and pH assessments were repeated. Results: Data were analysed from 35 patients who completed all scheduled assessments and had 24-hour monitoring for each end-point. Mean time pH \u3e 4.0 and mean 24-hour pH were highest for esomeprazole 40 mg twice daily, followed by lansoprazole 30 mg twice daily, esomeprazole 40 mg once daily and lansoprazole 30 mg once daily. Esomeprazole 40 mg twice daily provided superior control of intragastric pH compared with either once or twice daily dosing of lansoprazole and once daily dosing of esomeprazole (P \u3c 0.01). Esomeprazole 40 mg once daily was comparable with lansoprazole 30 mg twice daily and both were superior to lansoprazole 30 mg once daily (P \u3c 0.01). Conclusions: Response to acid suppression treatment depends on the treatment selected. Esomeprazole 40 mg twice daily provided better control of intragastric pH than all other regimens evaluated. Esomeprazole 40 mg daily, however, was comparable with lansoprazole 30 mg twice daily and superior to lansoprazole 30 mg once daily
A 3-Month interdisciplinary Process Drama Program to Build Social Skills in Pre-Schoolers with ASD: A Feasibility Study
Objectives: To test the feasibility and effect of an interdisciplinary process drama program targeting social skill development in 3-5 year-old children with Autism Spectrum Disorder (ASD) characteristics To develop a paradigm for testing brain-behavior relationships related to social skills in these children using EEG and testing its ability to detect intervention-related changes.
Background: Social skill deficits are a hallmark cause of disability in ASD. Such disability is of critical concern given the rising prevalence (1 in 54 Utah children) of ASD. [1] As children learn through social experiences, difficulty in social interactions can limit development and ability to succeed in school and eventually employment. One possible contributor to social interaction difficulties in ASD is a deficit in theory of mind (ToM), the ability to understand others\u27 perspectives, proposed to rely on memories of cognitive and emotional events that allow one to experience others\u27 situations as if they were one\u27s own. [2.3] Children with ASD have deficits in ToM [2,3] and show aberrant neural activation patterns in areas most typically activated during ToM tasks in healthy children. [4,5] An effective intervention fostering generalizable social skill development in children with ASD remains elusive. We propose to address this need with an interdisciplinary process drama intervention involving collaboration among occupational therapists (OT), theatre faculty/teachers, and speech language pathologists (SLP) to improve social interactions in preschoolers with ASD. Process drama may be an excellent medium for fostering social skill development due to the ability to create specific learning experiences in an autotelic manner [6] in which people experience the embodied cognition and emotions without conscious commitment to abstract social skill improvement goals. The scenes can emphasize social and emotional cues and explicit identification of scene-related feelings for the formation of social cognitive and emotional memories that can be recalled as the basis for later social functioning.[3] Process drama programs foster communication development in typically developing children [7] and a few studies have shown such programs enhance social skills of children aged 8-17 with ASD [8,9] However, targeting process drama intervention in preschool children may have the greatest potential for effect on ToM and subsequent social skill development. The overpruning hypothesis [10] proposes that ASD results from abnormal neural pruning in widespread neural networks, with weaker long-range connections being more vulnerable to major disruption. As neural connections strengthen through experience,[11] providing interventions targeting desired processing will strengthen associated connections making them less susceptible to pruning and resulting in preserved function. Peak synaptic density for auditory and prefrontal cortices, both involved in social skills, occurs between age 3-5 years [11], suggesting an optimal period for strengthening connections through intervention.
Impact: The deficits in social skills of people with ASD significantly affect their ability to function in society. These deficits take a large toll on families and on independence and employability of the individual. Finding effective interventions to facilitate social skills would have a large impact on society by reducing disability in this prevalent population.
Results: The primary goal of the proposed study is to gather preliminary data on potential utility of an interdisciplinary process drama intervention to improve social skills in children with ASD. We will address the following specific aims:
1) determine the feasibility of:
a) the protocol for collecting neural activation data via EEG on preschoolers with ASD characteristics;
b) conducting a 3 month, 3x/week process drama intervention program led by a collaborative team of theatre teachers, OTs and SLPs aimed at improving social skills.
2) Determine preliminary effects of this interdisciplinary intervention on:
a) increasing positive social behaviors;
b) changes in neural activation during social tasks
Affective Decision-making Predictive of Chinese Adolescent Drinking Behaviors
The goal of the current investigation was to address whether affective decision making would serve as a unique neuropsychological marker to predict drinking behaviors among adolescents. We conducted a longitudinal study of 181 Chinese adolescents in Chengdu city, China. In their 10th grade (ages 15–16), these adolescents were tested for their affective decision-making ability using the Iowa Gambling Task (IGT) and working memory capacity using the Self-Ordered Pointing Test. Self-report questionnaires were used to assess academic performance and drinking behaviors. At 1-year follow-up, questionnaires were completed to assess drinking behaviors, and the UPPS Impulsive Behavior Scale was used to examine four dimensions of impulsivity: urgency, lack of premeditation, lack of perseverance, and sensation seeking. Results indicated that those adolescents who progressed to binge drinking or exhibited consistent binge drinking not only performed poorly on the IGT but also scored significantly higher in urgency compared to those who never or occasionally drank. Moreover, better IGT scores predicted fewer drinking problems and fewer drinks 1 year later after controlling for demographic variables, the previous drinking behaviors, working memory, and impulsivity. These findings suggest that deficits in affective decision making may be important independent determinants of compulsive drinking and potentially addictive behavior in adolescents.

Impact of Unexpected Events, Shocking News and Rumours on Foreign Exchange Market Dynamics
We analyze the dynamical response of the world's financial community to
various types of unexpected events, including the 9/11 terrorist attacks as
they unfolded on a minute-by-minute basis. We find that there are various
'species' of news, characterized by how quickly the news get absorbed, how much
meaning and importance is assigned to it by the community, and what subsequent
actions are then taken. For example, the response to the unfolding events of
9/11 shows a gradual collective understanding of what was happening, rather
than an immediate realization. For news items which are not simple economic
statements, and hence whose implications are not immediately obvious, we
uncover periods of collective discovery during which collective opinions seem
to oscillate in a remarkably synchronized way. In the case of a rumour, our
findings also provide a concrete example of contagion in inter-connected
communities. Practical applications of this work include the possibility of
producing selective newsfeeds for specific communities, based on their likely
impact
