Fuzzy neural network methodology applied to medical diagnosis

This paper presents a technique for building expert systems that combines the fuzzy-set approach with artificial neural network structures. This technique can effectively deal with two types of medical knowledge: a nonfuzzy one and a fuzzy one which usually contributes to the process of medical diagnosis. Nonfuzzy numerical data is obtained from medical tests. Fuzzy linguistic rules describing the diagnosis process are provided by a human expert. The proposed method has been successfully applied in veterinary medicine as a support system in the diagnosis of canine liver diseases

Improving group dynamics to support learning and social inclusion: developing and enhancing CPD tutor capacity (Growing Talent for Inclusion, GTI) : Improving group dynamics to support learning and social inclusion developing and enhancing CPD tutor capacity

This project is based on the premise that students’ motivation to learn and achieve in school can be affected by difficult interpersonal relationships in class. This situation can produce high levels of unacceptable behaviour and possibly lead to students becoming socially excluded. The aim of this project, which we have called Growing Talent for Inclusion (GTI), is to promote more effective interpersonal relationships by identifying what is already working in the class rather than focusing on the difficulties and problems. The GTI process is based on Appreciative Inquiry, Solution Focused Thinking and collaborative consultation. The researchers involved in this project had already used this approach in a number of classes in Key Stages 2 and 3 across a range of primary, middle and secondary schools in Northamptonshire. During 2008-9, they worked with a focus group of Educational Psychologists , SENCO’s and Inclusion Managers to produce , pilot and evaluate a set of resources to enable Educational Psychologists, tutors working in ITT and CPD and teachers to use this approach, in schools and other learning contexts

Parents’ Perception of Overweight in Relation to Child Mood and Disordered Eating

Parental perception of their child’s weight may impact child’s psychological functioning; however, there is a dearth of literature examining this relationship. Data suggest that parental concern with child’s overweight may be related to child distress and/or disordered eating. Yet, it is unknown if parents’ perception of teens’ overweight relates to child functioning. We examined 113 adolescent (12-17y; 14.4 ± 1.6) boys and girls (53% girls) with overweight or obesity (BMIz 2.0 ± .45) and their parents. Youth self-identified as 53% Caucasian or White, 27% Black or African American, 3.5% Asian, and 16.5% multiple races, unknown, or other. Parents reported on their perception of their child’s overweight as either “somewhat/sometimes true” and “very/often true.” Teens reported on their symptoms of anxiety and depression and whether they had experienced loss-of-control eating in the past month. T-tests and Chi Square analyses were used to analyze child factors based on parent perceptions. Compared to parents who reported “somewhat/sometimes true” (n = 51), parents who reported “very/often true” (n = 62), had children with significantly higher anxiety (p = .048) and higher likelihood of reporting loss-of-control eating in the past month (p = .039). There were no differences in symptoms of depression. Including sex, race, and BMIz as covariates did not alter findings. In summary, youth whose parents perceive their children as more definitively overweight are more likely to report symptoms of anxiety and disordered eating. Further data are needed to determine if parental perception is related to their adolescent child’s overall well-being

Three-dimensional cell to tissue assembly process

The present invention relates a 3-dimensional cell to tissue and maintenance process, more particularly to methods of culturing cells in a culture environment, either in space or in a gravity field, with minimum fluid shear stress, freedom for 3-dimensional spatial orientation of the suspended particles and localization of particles with differing or similar sedimentation properties in a similar spatial region

Dietetic Students’ Changes in Attitudes after Participating in Online Interprofessional Education

Interprofessional education (IPE) is an accreditation requirement and an important component of training for future registered dietitian nutritionists (RDNs) and access to quality IPE is often limited in online programs. An online IPE module was developed to provide dietetics students the opportunity to build collaborative skills with students in other healthcare training programs. A research study was designed to answer the following research question: How and to what extent does participation in an online IPE module impact online dietetics students’ attitudes of interprofessional practice? Participants were dietetics students enrolled in an upper-division online dietetics course. Data gathered included a retrospective pre-post survey, reflection journal entries, and focus group interviews. Results suggested that the online IPE intervention had a positive impact on dietetics students’ attitudes of interprofessional practice and enhanced their understanding of the roles of members of the interprofessional team. The opportunity for participants to work on a final project as part of an interprofessional team likely contributed to the positive shared learning experiences and overall growth in interprofessional collaboration

Adaptively selecting occupations to detect skill shortages from online job ads

Labour demand and skill shortages have historically been difficult to assess given the high costs of conducting representative surveys and the inherent delays of these indicators. This is particularly consequential for fast developing skills and occupations, such as those relating to Data Science and Analytics (DSA). This paper develops a data-driven solution to detecting skill shortages from online job advertisements (ads) data. We first propose a method to generate sets of highly similar skills based on a set of seed skills from job ads. This provides researchers with a novel method to adaptively select occupations based on granular skills data. Next, we apply this adaptive skills similarity technique to a dataset of over 6.7 million Australian job ads in order to identify occupations with the highest proportions of DSA skills. This uncovers 306,577 DSA job ads across 23 occupational classes from 2012-2019. Finally, we propose five variables for detecting skill shortages from online job ads: (1) posting frequency; (2) salary levels; (3) education requirements; (4) experience demands; and (5) job ad posting predictability. This contributes further evidence to the goal of detecting skills shortages in real-time. In conducting this analysis, we also find strong evidence of skills shortages in Australia for highly technical DSA skills and occupations. These results provide insights to Data Science researchers, educators, and policy-makers from other advanced economies about the types of skills that should be cultivated to meet growing DSA labour demands in the future

Impact of cyclooxygenase inhibitors in the Women's Health Initiative hormone trials: secondary analysis of a randomized trial.

OBJECTIVES: We evaluated the hypothesis that cyclooxygenase (COX) inhibitor use might have counteracted a beneficial effect of postmenopausal hormone therapy, and account for the absence of cardioprotection in the Women's Health Initiative hormone trials. Estrogen increases COX expression, and inhibitors of COX such as nonsteroidal anti-inflammatory agents appear to increase coronary risk, raising the possibility of a clinically important interaction in the trials. DESIGN: The hormone trials were randomized, double-blind, and placebo-controlled. Use of nonsteroidal anti-inflammatory drugs was assessed at baseline and at years 1, 3, and 6. SETTING: The Women's Health Initiative hormone trials were conducted at 40 clinical sites in the United States. PARTICIPANTS: The trials enrolled 27,347 postmenopausal women, aged 50-79 y. INTERVENTIONS: We randomized 16,608 women with intact uterus to conjugated estrogens 0.625 mg with medroxyprogesterone acetate 2.5 mg daily or to placebo, and 10,739 women with prior hysterectomy to conjugated estrogens 0.625 mg daily or placebo. OUTCOME MEASURES: Myocardial infarction, coronary death, and coronary revascularization were ascertained during 5.6 y of follow-up in the estrogen plus progestin trial and 6.8 y of follow-up in the estrogen alone trial. RESULTS: Hazard ratios with 95% confidence intervals were calculated from Cox proportional hazard models stratified by COX inhibitor use. The hazard ratio for myocardial infarction/coronary death with estrogen plus progestin was 1.13 (95% confidence interval 0.68-1.89) among non-users of COX inhibitors, and 1.35 (95% confidence interval 0.86-2.10) among continuous users. The hazard ratio with estrogen alone was 0.92 (95% confidence interval 0.57-1.48) among non-users of COX inhibitors, and 1.08 (95% confidence interval 0.69-1.70) among continuous users. In a second analytic approach, hazard ratios were calculated from Cox models that included hormone trial assignment as well as a time-dependent covariate for medication use, and an interaction term. No significant interaction was identified. CONCLUSIONS: Use of COX inhibitors did not significantly affect the Women's Health Initiative hormone trial results
