Types of cost in inductive concept learning

Inductive concept learning is the task of learning to assign cases to a discrete set of classes. In real-world applications of concept learning, there are many different types of cost involved. The majority of the machine learning literature ignores all types of cost (unless accuracy is interpreted as a type of cost measure). A few papers have investigated the cost of misclassification errors. Very few papers have examined the many other types of cost. In this paper, we attempt to create a taxonomy of the different types of cost that are involved in inductive concept learning. This taxonomy may help to organize the literature on cost-sensitive learning. We hope that it will inspire researchers to investigate all types of cost in inductive concept learning in more depth

Simulación y competencias no técnicas en el contexto de emergencia pre-hospitalar: estudio cualitativo

Unidade de Monitorização em Indicadores de Saúde - UMISAbstract - To understand the importance that nurses assign to simulation in the development of non-technical skills in cardiac arrest event in pre-hospital setting. Background Nursing is projected in the future, developing a patient centred approach consistent with the values, needs and desires of patients, considering process of care as a complex intervention. Simulation based on scenarios is an opportunity to recreate this complexity in a virtual way, to develop the non-technical skills. Methods This study uses an inductive, interpretative and constructivist qualitative research. 7 nurses were interviewed. It was developed a thematic analysis content. Results Three themes were identified: Simulation scenarios in pre-hospital emergencies; The acquisition of knowledge to skills development and Construction of the virtual from the real Conclusions The interviewed nurses present weakness of knowledge about simulation types. Debriefing is relevant to the learning skills: critical thinking. thinking, clinical judgement and decision making.Resumo - Compreender a importância que os enfermeiros atribuem à simulação no desenvolvimento de competências não técnicas no evento paragem cardíaca em ambiente préhospitalar. Enquadramento A enfermagem é projetada no futuro, desenvolvendo uma abordagem centrada na pessoa consistente com a valorização de valores, necessidades e desejos destes, considerando o processo de cuidados como intervenção complexa. A simulação baseada em cenários é uma oportunidade para recriar essa complexidade de forma virtual, no desenvolvimento de competências não-técnicas. Metodologia Este estudo utiliza uma pesquisa qualitativa indutiva, interpretativa e construtivista. Foram entrevistados 7 enfermeiros. Foi desenvolvida análise de conteúdo temática. Resultados Foram identificados três temas: cenários de simulação em emergências pré-hospitalares; A aquisição de conhecimento para o desenvolvimento de habilidades e Construção do virtual a partir do real. Conclusões Os enfermeiros entrevistados apresentam conhecimentos a melhorar em relação aos tipos de simulação. Consideram o Debriefing relevante para as habilidades de aprendizagem: pensamento crítico, julgamento clínico e a tomada de decisão.Resumen - Comprender la importancia que los enfermeros atribuyen a la simulación en el desarrollo de competencias no técnicas en el evento paro cardíaco en ambiente prehospitalario.

Assessing the probability of patients reoffending after discharge from low to medium secure forensic mental health services: An inductive prevention paradox

Citizens of developed societies are troubled by those who commit ‘irrational' crimes against the person. Reoffending by ex-patients following their release from secure mental health services triggers particularly intense angst when amplified by media and political scrutiny. Forensic mental health service providers are expected to minimise the occurrence of such transgressions by releasing only those patients who are judged acceptably unlikely to reoffend. However, reoffending probabilities can only be estimated by observing behaviour in secure institutional settings designed specifically to prevent patients from transgressing. The article explores this ‘inductive prevention paradox' which arises when the implementation of measures designed to avoid an adverse event obscures direct observation of what might have happened if prophylaxis had not been attempted. The analysis presented draws on data obtained in 1999–2003 from two qualitative studies in medium to low secure UK institutions, one providing forensic mental health services and the other forensic learning disability services. We explored the views of 56 staff members and 21 patients about risk management in forensic services and undertook additional 25 staff interviews for case studies of the 21 patients. The wider applicability of the inductive prevention paradox will be considered in the Discussion. We argue that the prognostic limitations arising from prevention have been underestimated by policy makers and in official inquiries; and that the prevailing personal risk assessment framework needs to be complemented by greater attention to the environments which patients will be discharged into

Developing minimum clinical standards for physiotherapy in South African ICUs: A qualitative study

Rationale, aims, and objectives: Physiotherapists are integral members of the intensive care unit (ICU) team. Clinicians working in ICU are dependent on their own experience when making decisions regarding individual patient management thus resulting in variation in clinical practice. No formalized clinical practice guidelines or standards exist for the educational profile or scope of practice requirements for ICU physiotherapy. This study explored perceptions of physiotherapists on minimum clinical standards that ICU physiotherapists should adhere to for delivering safe, effective physiotherapy services to critically ill patients. Method: Experienced physiotherapists offering a service to South African ICUs were purposively sampled. Three focus group sessions were held in different parts of the country to ensure national participation. Each was audio recorded. The stimulus question posed was “What is the minimum standard of clinical practice needed by physiotherapists to ensure safe and independent practice in South African ICUs?” Three categories were explored, namely, knowledge, skill, and attributes. Themes and subthemes were developed using the codes identified. An inductive approach to data analysis was used to perform conventional content analysis. Results: Twenty-five physiotherapists participated in 1 of 3 focus group sessions. Mean years of ICU experience was 10.8 years (±7.0; range, 3-33). Three themes emerged from the data namely, integrated medical knowledge, multidisciplinary teamwork, and physiotherapy practice. Integrated medical knowledge related to anatomy and physiology, conditions that patients present with in ICU, the ICU environment, pathology and pathophysiology, and pharmacology. Multidisciplinary teamwork encompassed elements related to communication, continuous professional development, cultural sensitivity, documentation, ethics, professionalism, safety in ICU, and technology. Components related to physiotherapy practice included clinical reasoning, handling skills, interventions, and patient care. Conclusions: The information obtained will be used to inform the development of a list of standards to be presented to the wider national physiotherapy and ICU communities for further consensus-building activities

Public Trust in Science: Exploring the Idiosyncrasy-Free Ideal

What makes science trustworthy to the public? This chapter examines one proposed answer: the trustworthiness of science is based at least in part on its independence from the idiosyncratic values, interests, and ideas of individual scientists. That is, science is trustworthy to the extent that following the scientific process would result in the same conclusions, regardless of the particular scientists involved. We analyze this "idiosyncrasy-free ideal" for science by looking at philosophical debates about inductive risk, focusing on two recent proposals which offer different methods of avoiding idiosyncrasy: the high epistemic standards proposal and the democratic values proposal
