The management of context-sensitive features: A review of strategies

In this paper, we review five heuristic strategies for handling context- sensitive features in supervised machine learning from examples. We discuss two methods for recovering lost (implicit) contextual information. We mention some evidence that hybrid strategies can have a synergetic effect. We then show how the work of several machine learning researchers fits into this framework. While we do not claim that these strategies exhaust the possibilities, it appears that the framework includes all of the techniques that can be found in the published literature on context-sensitive learning

Canada

Excerpt: The first Europeans to inhabit what is now Canada came from Norse countries about 1000 AD to spend at least two winters at L’Anse aux Meadows, on the northwestern tip of Newfoundland. No evidence remains of any Christian religious activity on the part of these occupants. During the age of exploration, Europeans from many nations came to Canada for various reasons, including trade, political expansion, and Christian missions to the First Nations peoples already resident in Canada. As a result of such mission work, and the replication or expansion of churches from the European countries of origin of Canadian immigrants, church-sponsored education was widespread by the time Canada gained nationhood in 1867

Prevalence and correlates of antibodies to Neospora caninum in dogs in Portugal

Neosporosis, caused by Neospora caninum, is an important cause of abortion in cattle and of neurological disease in dogs. This study investigated the prevalence and correlates of antibodies to N. caninum in 441 dogs from the five regions of mainland Portugal. A commercial competitive enzyme-linked immunosorbent assay (cELISA) was used and specific antibodies were detected in 35 (7.9%) dogs. Seroprevalence levels were significantly different among some of the studied regions, as well as between stray dogs (13.6%) and hunting dogs (1.7%). The difference between seropositivity in dogs presenting musculoskeletal or neurological signs (21.4%) and that in animals without clinical signs compatible with neosporosis (5.6%) was close to statistical significance. This is the first report on the seroprevalence of N. caninum in dogs in Portugal. Neosporosis should be considered in the differential diagnosis of neurological disorders of dogs.National Funds through FCT - Foundation for Science and Technology under the Strategic Project [PEst-OE/AGR/UI0115/2014]; FCT [SFRH/BPD/44082/2008]info:eu-repo/semantics/publishedVersio

Stability, Resonance and Lyapunov Inequalities for Periodic Conservative Systems

This paper is devoted to the study of Lyapunov type inequalities for periodic conservative systems. The main results are derived from a previous analysis which relates the best Lyapunov constants to some especial (constrained or unconstrained) minimization problems. We provide some new results on the existence and uniqueness of solutions of nonlinear resonant and periodic systems. Finally, we present some new conditions which guarantee the stable boundedness of linear periodic conservative systems.Comment: 19 page

Effects of empagliflozin on cardiorespiratory fitness and significant interaction of loop diuretics

The effects of empagliflozin on cardiorespiratory fitness in patients with type 2 diabetes mellitus (T2DM) and heart failure with reduced ejection fraction (HFrEF) are unknown. In this pilot study we determined the effects of empagliflozin 10 mg/d for 4 weeks on peak oxygen consumption (VO2 ) in 15 patients with T2DM and HFrEF. As an exploratory analysis, we assessed whether there was an interaction of the effects of empagliflozin on peak VO2 of loop diuretics. Empagliflozin reduced body weight (-1.7 kg; P = .031), but did not change peak VO2 (from 14.5 mL kg-1 min-1 [12.6-17.8] to 15.8 [12.5-17.4] mL kg-1 min-1 ; P = .95). However, patients using loop diuretics (N = 9) demonstrated an improvement, whereas those without loop diuretics (N = 6) experienced a decrease in peak VO2 (+0.9 [0.1-1.4] vs -0.9 [-2.1 to -0.3] mL kg-1 min-1 ; P = .001), and peak VO2 changes correlated with the baseline daily dose of diuretics (R = +0.83; P < .001). Empagliflozin did not improve peak VO2 in patients with T2DM and HFrEF. However, as a result of exploratory analysis, patients concomitantly treated with loop diuretics experienced a significant improvement in peak VO2

Would a student midwife run postnatal clinic make a valuable addition to midwifery education in the UK? - A systematic review

Background – There is growing evidence in the UK that some National Health Service improvements, particularly in the postnatal period, are having an impact on the quality and variety of student midwives’ clinical experiences, making it challenging for them to meet the standards set by the regulatory body for midwives and receive a licence to practice. A possible solution to this may be the introduction of a Student Midwife integrated Learning Environment (SMiLE) focusing upon the delivery of postnatal care (PN) through a student run clinic Objective - To identify the current state of knowledge, regarding the educational outcomes of students who engage with student run clinics (SRC) and the satisfaction of patients who attend them Search strategy - BNI, CINAHL, EMBASE, MEDLINE were searched for articles published until April 2014. Selection criteria - Studies nationally and internationally, that were carried out on healthcare students running their own clinics. Outcome measures were the evaluation of educational outcomes of students and client satisfaction were included Data collection and analysis - Data were extracted, analysed and synthesised to produce a summary of knowledge, regarding the effectiveness of SRC’s Main results - 6 studies were selected for this review Authors conclusions – The findings that SRC can offer advantages in improving educational outcomes of students and provide an effective service to clients is encouraging. However, given the limited number of high-quality studies included in this review, further research is required to investigate the effectiveness of SR

Factors associated with not seeking professional help or disclosing intent prior to suicide : A study of medical examiners' records in Nova Scotia

Individual-level data from clinical settings lack information on people who did not seek professional help prior to suicide. We used records of the Nova Scotia Medical Examiner Service (NSMES) to compare people who had contact with a health professional prior to suicide with those who did not.We linked data from the NSMES to routine administrative data of the province.The NSMES recorded 108 suicides in Nova Scotia from January 1, 2006, to December 31, 2006; there were 90 male and 18 female suicide deaths. Mean and median age at death were 44.73 (SD 13.33) and 44 years, respectively. Patients aged 40 to 49 years made up one-third of the cases (n = 35) and this was the decade of life with the highest number of suicides. This was also the group least likely to have suicidal intent recorded in the NSMES files (χ(2) = 3.86, df = 1, P = 0.05). Otherwise, there were no significant differences between people who sought help, or disclosed intent, prior to suicide and people who did not. The samples in all cases were predominately male and single.People aged 40 to 49 years were the age group with the highest absolute number of suicides, but were the least likely to have suicidal intent recorded in the NSMES files. This finding merits further investigation. Medical examiner or coroner data may provide additional information not obtained elsewhere for the surveillance of suicide
