The development and expression of canine emotion

In her review of canine emotions, Kujala (2017) discusses how humans often attribute emotions such as fear, love, and jealousy to their canine companions. This attribution is often dismissed as anthropomorphism, suggesting that only humans can possess these emotions. I argue that emotions are not something we possess but features of certain behavioral patterns. Both human and canine emotions arise through evolution and conditioning; examining their development and expression may lead to new insights about both canine and human behavior

Influence of social facilitation and gender differences on purchasing behavior of consumers in a mall

Consumers were observed in order to investigate whether it is more likely that lone or group shoppers will make a purchase and to what extent gender differences in purchasing behavior exist. As shoppers exited a Georgia mall, variables such as gender, group orientation, and the presence or absence of a package were recorded. Observations revealed that of 1269 shoppers, nearly 54% of lone shoppers made purchases, compared to 41% of group shoppers, and women carried packages more often than did men. Both the comparison of lone versus group shoppers and the difference in men\u27s and women\u27s buying showed p\u3c.05 from a test for significance between two proportions. Contrary to the social facilitation theory, group shoppers did not consume more than lone individuals. This study suggests that social facilitation effects may be unique to particular environments

Meteorological satellites

An overview is presented of the meteorological satellite programs that have been evolving from 1958 to the present, and plans for the future meteorological and environmental satellite systems that are scheduled to be placed into service in the early 1980's are reviewed. The development of the TIROS family of weather satellites, including TIROS, ESSA, ITOS/NOAA, and the present TIROS-N (the third generation operational system) is summarized. The contribution of the Nimbus and ATS technology satellites to the development of the operational-orbiting and geostationary satellites is discussed. Included are descriptions of both the TIROS-N and the DMSP payloads currently under development to assure a continued and orderly growth of these systems into the 1980's

The Effects of Olfactory Enrichment on Shelter Dog Behavior

Shelter environments are stressful for dogs due to loud noises and unfamiliar surroundings. Previous research showed that exposure to some scents resulted in reductions in activity and vocalizations in shelter dogs. We investigated the effects of two calming (lavender and vetiver) and two stimulating (lemon and rosemary) essential oils on crate position and active, resting, and stress behaviors. There were 8, 5-min observations conducted each week per dog, split between baseline and scent exposure. Our analysis using the Wilcoxon Signed-Rank test found that dogs exposed to lavender (n = 13), lemon (n = 10), rosemary (n = 13), and vetiver (n = 12) did not show a significant difference in crate position or amount of time they engaged in stress, resting, or active behaviors compared to baseline. The lack of behavioral improvement indicates that scent enrichment alone may not be enough to have a significant effect on shelter dog behavior

454-Pyrosequencing: A Molecular Battiscope for Freshwater Viral Ecology

Viruses, the most abundant biological entities on the planet, are capable of infecting organisms from all three branches of life, although the majority infect bacteria where the greatest degree of cellular diversity lies. However, the characterization and assessment of viral diversity in natural environments is only beginning to become a possibility. Through the development of a novel technique for the harvest of viral DNA and the application of 454 pyrosequencing, a snapshot of the diversity of the DNA viruses harvested from a standing pond on a cattle farm has been obtained. A high abundance of viral genotypes (785) were present within the virome. The absolute numbers of lambdoid and Shiga toxin (Stx) encoding phages detected suggested that the depth of sequencing had enabled recovery of only ca. 8% of the total virus population, numbers that agreed within less than an order of magnitude with predictions made by rarefaction analysis. The most abundant viral genotypes in the pond were bacteriophages (93.7%). The predominant viral genotypes infecting higher life forms found in association with the farm were pathogens that cause disease in cattle and humans, e.g. members of the Herpesviridae. The techniques and analysis described here provide a fresh approach to the monitoring of viral populations in the aquatic environment, with the potential to become integral to the development of risk analysis tools for monitoring the dissemination of viral agents of animal, plant and human diseases

Early Identification & Intervention: Is There “Hope” for At-Risk Law Students?

poster abstractPsychologists have defined hope as a cognitive style involving how people think about pursuing goals. Research by Snyder and colleagues has shown that hope predicts academic performance and psychological well-being among undergraduate students. Consistent with these findings, our prospective study of hope, optimism, academic performance, and psychological well-being in law students showed that hope predicted academic performance in the first semester of law school above and beyond previous academic achievement. Moreover, hope predicted life satisfaction during the last week of the semester. Thus, assessing for low hope in those entering law school may help to identify students at risk for academic underperformance and psychological maladjustment. Once low-hope students have been identified, legal educators can intervene by employing five strategies for engendering hope: (A) optimizing student goals; (B) increasing student autonomy; (C) modeling the learning process; (D) helping students understand evaluation as feedback; and (E) modeling agency. These strategies, derived from Snyder’s hope theory, are grounded in contemporary teaching and learning theories and are consistent with principles discussed in Best Practices for Legal Education. By identifying low-hope students early and intervening to improve their hope, legal educators may be able to improve their academic performance, enhance their life satisfaction, increase their bar passage rates, and, eventually, build a happier and more competent generation of lawyers

An experimental test of deviant modeling

Objectives: Test the effect of deviant peer modeling on theft as conditioned by verbal support for theft and number of deviant models. Methods: Two related randomized experiments in which participants were given a chance to steal a gift card (ostensibly worth $15) from the table in front of them. Each experiment had a control group, a verbal prompting group in which confederate(s) endorsed stealing, a behavioral modeling group in which confederate(s) committed theft, and a verbal prompting plus behavioral modeling group in which confederate(s) did both. The first experiment used one confederate; the second experiment used two. The pooled sample consisted of 335 undergraduate students. Results: Participants in the verbal prompting plus behavioral modeling group were most likely to steal followed by the behavioral modeling group. Interestingly, behavioral modeling was only influential when two confederates were present. There were no thefts in either the control or verbal prompting groups regardless of the number of confederates. Conclusions: Behavioral modeling appears to be the key mechanism, though verbal support can strengthen the effect of behavioral modeling.UW/SSHRC Seed Gran

Targeted, structured text messaging to improve dietary and lifestyle behaviours for people on maintenance haemodialysis (KIDNEYTEXT): Study protocol for a randomised controlled trial

Introduction Managing nutrition is critical for reducing morbidity and mortality in patients on haemodialysis but adherence to the complex dietary restrictions remains problematic. Innovative interventions to enhance the delivery of nutritional care are needed. The aim of this phase II trial is to evaluate the feasibility and effectiveness of a targeted mobile phone text messaging system to improve dietary and lifestyle behaviours in patients on long-term haemodialysis. Methods and analysis Single-blinded randomised controlled trial with 6 months of follow-up in 130 patients on haemodialysis who will be randomised to either standard care or KIDNEYTEXT. The KIDNEYTEXT intervention group will receive three text messages per week for 6 months. The text messages provide customised dietary information and advice based on renal dietary guidelines and general healthy eating dietary guidelines, and motivation and support to improve behaviours. The primary outcome is feasibility including recruitment rate, drop-out rate, adherence to renal dietary recommendations, participant satisfaction and a process evaluation using semistructured interviews with a subset of purposively sampled participants. Secondary and exploratory outcomes include a range of clinical and behavioural outcomes and a healthcare utilisation cost analysis will be undertaken. Ethics and dissemination The study has been approved by the Western Sydney Local Health District Human Research Ethics Committee-Westmead. Results will be presented at scientific meetings and published in peer-reviewed publications. Trial registration number ACTRN12617001084370; Pre-results
