Gender Differences in Self-Attribution and Overconfidence in Financial Decisions
Behavioral finance and the study into biases is a rapidly increasing area of interest for finance professionals and academics alike. Understanding the sources of overconfidence and the self-attribution bias from a gendered framework can provide insight for managers and industry leaders to insulate their firms from underperformance losses due to these biases. Education and relevant financial experience are key controllable variables that impact overconfidence and self- attribution. Using a survey sent to around 130 students and finance professionals, gender, education, and relevant experience were tested against overconfidence and self-attributional scores to determine if there were any meaningful relationships. The results suggest that gender, education, and experience are all significant magnifiers of potentially harmful biases. As the finance industry grows more demographically representative, the industry leadership and academic datasets need to reflect that trend, a gap which this research aims to address
Prawn Shell Chitosan Has Anti-Obesogenic Properties, Influencing Both Nutrient Digestibility and Microbial Populations in a Pig Model
This study was supported financially
(Grant-Aid Agreement No. MFFRI/07/01) under the Sea Change Strategy with the support of the Marine Institute and the Department of Agriculture, Food and the Marine, funded under the National Development Plan 2007–2013.peer-reviewedThe potential of natural products to prevent obesity have been investigated, with evidence
to suggest that chitosan has anti-obesity effects. The current experiment investigated the
anti-obesity potential of prawn shell derived chitosan on a range of variables relevant to
obesity in a pig model. The two dietary treatment groups included in this 63 day study were:
T1) basal diet and T2) basal diet plus 1000 ppm chitosan (n = 20 gilts per group (70 ± 0.90
kg). The parameter categories which were assessed included: performance, nutrient digestibility,
serum leptin concentrations, nutrient transporter and digestive enzyme gene expression
and gut microbial populations. Pigs offered chitosan had reduced feed intake and final
body weight (P< 0.001), lower ileal digestibility of dry matter (DM), gross energy (GE) (P<
0.05) and reduced coefficient of apparent total tract digestibility (CATTD) of gross energy
and nitrogen (P<0.05) when compared to the basal group. Fatty acid binding protein 2
(FABP2) gene expression was down-regulated in pigs offered chitosan (P = 0.05) relative to
the basal diet. Serum leptin concentrations increased (P< 0.05) in animals offered the chitosan
diet compared to pigs offered the basal diet. Fatness traits, back-fat depth (mm), fat
content (kg), were significantly reduced while lean meat (%) was increased (P<0.05) in chitosan
supplemented pigs. Pigs offered chitosan had decreased numbers of Firmicutes in
the colon (P <0.05), and Lactobacillus spp. in both the caecum (P <0.05) and colon (P
<0.001). Bifidobacteria populations were increased in the caecum of animals offered the
chitosan diet (P <0.05). In conclusion, these findings suggest that prawn shell chitosan has
potent anti-obesity/body weight control effects which are mediated through multiple biological
systems in vivo.This study was supported financially

Shared Journaling as Peer Support in Teaching Qualitative Research Methods
Teaching qualitative research methods (QRM), particularly early on in one’s academic career, can be challenging. This paper describes shared peer journaling as one way in which to cope with challenges such as complex debates in the field and student resistance to interpretive paradigms. Literature on teaching QRM and the pedagogical value of journaling for metacognition are reviewed. The two authors describe key points about their teaching contexts and then demonstrate with journal excerpts how they developed (a) clarity, (b) confidence, and (c) connection through two years of co-creating their journal. The article concludes with recommendations for shared journal writing as well as ways to extend it
Service users experiences of a therapeutic group programme in an acute psychiatric inpatient unit.
Psychiatric nurses have been facilitating therapeutic groups in acute psychiatric inpatient units for many years; however, there is a lack of nursing research related to this important aspect of care. This paper reports the findings of a study which aimed to gain an understanding of service users' experiences in relation to therapeutic group activities in an acute inpatient unit. A qualitative descriptive study was undertaken with eight service users in one acute psychiatric inpatient unit in Ireland. Data were collected using in-depth semi-structured interviews and analysed using Burnard's method of thematic content analysis. Several themes emerged from the findings which are presented in this paper
Investigation of the Use of an Authentic Learning Environment for Development of Graduate Attributes in Third Year Chemistry Students
This work describes the redesign of a Quality Assurance and Validation module for third year students in the School of Chemical and Pharmaceutical Sciences at Dublin Institute of Technology in Ireland. The module, which had been previously assessed by summative examination, was changed to a completely continuously assessed module. The students had to work in teams to complete a series of tasks, reflective of those performed in various regulated environments. The development of graduate attributes during the module was assessed by a survey instrument. Students from two class groups (2016 and 2017) were assessed on their perception of the development of both technical and soft skills. The results showed that students perceived themselves to have improved in technical knowledge, communication skills and organisational skills, upon completion of the new module. The students identified the use of teamwork as the aspect of the module they most enjoyed
Young students' use of the internet for mental health information and support
It is recognized that young people experience difficulties in accessing mainstream mental health services particularly because of the stigma that remains associated with mental health problems. One potential solution is to use the many websites available offering information and support for mental health problems, such support and information could be offered by Psychiatric Nurses. However, young peoples' usage and views on using the Internet for this purpose has yet to be examined. This quantitative descriptive study aimed to elicit the views of 922 University students, aged between 18 and 24 years, on using the Internet for mental health information and support. Data were collected using a 30-item self-designed questionnaire and analysed using descriptive statistics. The findings indicated that 72.4% of participants used the Internet several times a day. In addition, 30.8% had previously searched for mental health information online, predominantly on depression. While it was found that 68% of participants indicated that they would use the Internet for mental health support if they needed to, 79.4% would still prefer face to face support. It is concluded that young people are willing to use the Internet for mental health information and that it represents a viable source of support for this age group
Environmental enrichment facilitates cocaine-cue extinction, deters reacquisition of cocaine self-administration and alters AMPAR GluA1 expression and phosphorylation
This study investigated the combination of environmental enrichment (EE) with cocaine‐cue extinction training on reacquisition of cocaine self‐administration. Rats were trained under a second‐order schedule for which responses were maintained by cocaine injections and cocaine‐paired stimuli. During three weekly extinction sessions, saline was substituted for cocaine but cocaine‐paired stimuli were presented. Rats received 4‐h periods of EE at strategic time points during extinction training, or received NoEE. Additional control rats received EE or NoEE without extinction training. One week later, reacquisition of cocaine self‐administration was evaluated for 15 sessions, and then GluA1 expression, a cellular substrate for learning and memory, was measured in selected brain regions. EE provided both 24 h before and immediately after extinction training facilitated extinction learning and deterred reacquisition of cocaine self‐administration for up to 13 sessions. Each intervention by itself (EE alone or extinction alone) was ineffective, as was EE scheduled at individual time points (EE 4 h or 24 h before, or EE immediately or 6 h after, each extinction training session). Under these conditions, rats rapidly reacquired baseline rates of cocaine self‐administration. Cocaine self‐administration alone decreased total GluA1 and/or pSer845GluA1 expression in basolateral amygdala and nucleus accumbens. Extinction training, with or without EE, opposed these changes and also increased total GluA1 in ventromedial prefrontal cortex and dorsal hippocampus. EE alone increased pSer845GluA1 and EE combined with extinction training decreased pSer845GluA1 in ventromedial prefrontal cortex. EE might be a useful adjunct to extinction therapy by enabling neuroplasticity that deters relapse to cocaine self‐administration.The authors declare no competing financial interests.

An evaluation of an online peer support forum for university students with depressive symptoms
Background: Depression is the most common mental health problem among young people, particularly university students, with prevalence rates as high as 48% reported. This population however, is reluctant to seek professional help. Online interventions may be particularly appealing to students, with evidence suggesting that they use the Internet for mental health support. While there are many mental health resources on the Internet few focus specifically on the needs of young people and few have been evaluated. This research aimed to develop and pilot test an online peer support intervention for students experiencing depressive symptoms. Methods: A depression support Web site (www.losetheblues.ie) was designed specifically for 18-24. year old students. The study used a mixed method, involving quantitative descriptive, pre- and post-test and qualitative descriptive designs. Data were collected using the Centre for Epidemiological Studies Depression Scale (CES-D), a background questionnaire and online forum posts. Results: The sample consisted of 117 university students with self-reported depressive symptoms. Results from participants in the pre- and post-test element of the study, showed no statistical significance. The forum posts revealed that the participants' main difficulties were loneliness and perceived lack of socialization skills. The Web site provided a place for sharing, offering and receiving emotional and informational support. Conclusion: Developing health care interventions in an online environment presents unique challenges to the research process, however they have the potential to provide mental health care that is accessible and affordable
Perceptions of health risk among parents of overweight children: a cross-sectional study within a cohort.
OBJECTIVE: To identify the socio-demographic and behavioural characteristics associated with perceptions of weight-related health risk among the parents of overweight children. METHODS: Baseline data from a cohort of parents of children aged 4-11 years in five areas in England in 2010-2011 were analysed; the sample was restricted to parents of overweight children (body mass index ≥ 91(st) centile of UK 1990 reference; n=579). Associations between respondent characteristics and parental perception of health risk associated with their child's weight were examined using logistic regression analyses. RESULTS: Most parents (79%) did not perceive their child's weight to be a health risk. Perception of a health risk was associated with recognition of the child's overweight status (OR 10.59, 95% CI 5.51 to 20.34), having an obese child (OR 4.21, 95% CI 2.28 to 7.77), and having an older child (OR 2.67, 95% CI 1.32 to 5.41). However, 41% of parents who considered their child to be overweight did not perceive a health risk. CONCLUSIONS: Parents that recognise their child's overweight status, and the parents of obese and older children, are more likely to perceive a risk. However, many parents that acknowledge their child is overweight do not perceive a related health risk
Significant incidental cardiac disease on thoracic CT: what the general radiologist needs to know
Abstract
Objective
Incidental cardiac findings are often found on chest CT studies, some of which may be clinically significant. The objective of this pictorial review is to illustrate and describe the appearances and management of the most frequently encountered significant cardiac findings on non-electrocardiographically gated thoracic CT. Most radiologists will interpret multidetector chest CT and should be aware of the imaging appearances, significance, and the appropriate next management steps, when incidental significant cardiac disease is encountered on thoracic CT.
Conclusion
This article reviews significant incidental cardiac findings which may be encountered on chest CT studies. After completing this review, the reader should not only be familiar with recognizing clinically significant cardiac findings seen on thoracic CT examinations but also have the confidence to direct their further management.https://deepblue.lib.umich.edu/bitstream/2027.42/147739/1/13244_2019_Article_693.pd
