The fundamental theory of optimal "Anti-Bayesian" parametric pattern classification using order statistics criteria
2013
Author's version of an article in the journal: Pattern Recognition. Also available from the publisher at: http://dx.doi.org/10.1016/j.patcog.2012.07.004 The gold standard for a classifier is the condition of optimality attained by the Bayesian classifier. Within a Bayesian paradigm, if we are allowed to compare the testing sample with only a single point in the feature space from each class, the optimal Bayesian strategy would be to achieve this based on the (Mahalanobis) distance from the corresponding means. The reader should observe that, in this context, the mean, in one sense, is the most central point in the respective distribution. In this paper, we shall show that we can obtain opti…
Daily energy expenditure through the human life course
2021
Total daily energy expenditure (“total expenditure”, MJ/d) reflects daily energy needs and is a critical variable in human health and physiology, yet it is unclear how daily expenditure changes over the life course. Here, we analyze a large, globally diverse database of total expenditure measured by the doubly labeled water method for males and females aged 8 days to 95 yr. We show that total expenditure is strongly related to fat free mass in a power-law manner and identify four distinct metabolic life stages. Fat free mass-adjusted daily expenditure accelerates rapidly in neonates (0-1yr) to ~46% above adult values at ~1 yr, declines slowly throughout childhood and adolescence (1-20 yr) t…
Olfaction scaffolds the developing human from neonate to adolescent and beyond
2020
The impact of the olfactory sense is regularly apparent across development. The fetus is bathed in amniotic fluid (AF) that conveys the mother's chemical ecology. Transnatal olfactory continuity between the odours of AF and milk assists in the transition to nursing. At the same time, odours emanating from the mammary areas provoke appetitive responses in newborns. Odours experienced from the mother's diet during breastfeeding, and from practices such as pre-mastication, may assist in the dietary transition at weaning. In parallel, infants are attracted to and recognize their mother's odours; later, children are able to recognize other kin and peers based on their odours. Familiar odours, su…
Self-care telephone talks as a health-promotion intervention in urban home-living persons 75+ years of age: a randomized controlled study
2014
- Published article -cc-by-nc Aim: The aim of this study was to evaluate the effects of a telephone-based self-care intervention among urban living individuals 75+ years of age by comparing self-reported perceived health, mental health, sense of coherence, self-care ability, and self-care agency before and after the intervention. Materials and methods: In a randomized controlled study, 15 persons answered a questionnaire about perceived health, mental health, sense of coherence, self-care ability, and self-care agency. In a sex- and age-matched control group (n=15), the same questions were answered. Data were collected before and after intervention. An open-ended question about experiences …
Victimisation and life satisfaction of gay and bisexual individuals in 44 European countries: the moderating role of country-level and person-level a…
2018
We examined the link between victimisation and life satisfaction for 85,301 gay and bisexual individuals across 44 European countries. We expected this negative link to be stronger when the internalised homonegativity of the victim was high (e.g. because the victim is more vulnerable) and weaker when victimisation occurs in countries that express intolerance towards homosexuality (e.g. because in such contexts victims expect victimisation more and they attribute it to their external environment). Additionally, we expected internalised homonegativity to relate negatively to life satisfaction. Multilevel analyses revealed that victimisation (i.e. verbal insults, threats of violence, minor or …
GDS score as screening tool to assess the risk of impact of chronic conditions and depression on quality of life in hospitalized elderly patients in …
2021
Aging of population is characterized by multiple chronic conditions in the same individual. Health-related quality of life (HR-QOL) reflects the multidimensional impact of chronic disease on population and it is increasingly analysed as outcomes. The aim of this study was the evaluation of the predictors of quality of life among elderly patients hospitalized in internal medicine ward, investigating the effect of comorbidities on health-related quality of life. Data collected in this cross-sectional study were analysed. Socio-demographic, clinical characteristics, disease distribution and quality of life by the 12-Item Short Form Health Survey (SF-12) were evaluated. Of 240 inpatients, subje…
Identification of Risk Factors Associated with Obesity and Overweight-A Machine Learning Overview.
2020
Social determining factors such as the adverse influence of globalization, supermarket growth, fast unplanned urbanization, sedentary lifestyle, economy, and social position slowly develop behavioral risk factors in humans. Behavioral risk factors such as unhealthy habits, improper diet, and physical inactivity lead to physiological risks, and &ldquo
Business Intelligence i helsesektoren : erfaringer fra Diakonhjemmet Sykehus Kvalitativ studie med fokus på ledere i kliniske avdelinger
2017
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2017 Background: It is challenging to manage hospitals in Norway, partly due to changing economic frameworks and new demands from the government. Various information technologies are used in the health care system and many projects fail. Adoption of new technology is difficult in a complex organization with many different professional groups. Purpose: The purpose of this study is to investigate managers experiences with using a management information system (MIS) in clinical departments at a hospital in Norway. The system is self-developed at the hospital and is used by all levels of management. The aim is to investi…
ESTRUCTURAS ORGANIZATIVAS EN EMPRESAS DE INTERNACIONALIZACIÓN ACELERADA: EVIDENCIA EMPÍRICA
2014
Las pequeñas y medianas empresas internacionales pueden clasificarse en tradicionales, y empresas de internacionalización acelerada o born global. A pesar de que existe una variedad importante de investigaciones en el tema, ninguna ha establecido si existen diferencias entre la organización formal de una empresa de internacionalización acelerada y una empresa internacional tradicional. Mediante un estudio de casos a nivel comparativo, se establecen dos empresas internacionales tradicionales en la industria turística y de alimentos, y se analizan sus estructuras formales, con respecto a dos empresas en las mismas industrias con características de born global. Se determinan diferencias en los…
MÚSICA Y DESCARGA DE INTERNET: ANÁLISIS DE SUS ANTECEDENTES E IMPLICACIONES DE GESTIÓN
2014
La descarga de música de Internet es un fenómeno cada vez más extendido, que está causando importantes daños a la industria musical. Tomando como referencia la Teoría del Comportamiento Planeado, el presente trabajo trata de identificar las variables que condicionan la intención del individuo de descargarse música no autorizada, incorporando nuevas relaciones no contempladas explícitamente en la teoría considerada. Sólo conociendo el por qué del comportamiento se podrá valorar la posible instrumentalización de acciones a tendentes mejorar la situación por la que atraviesa la industria musical. A partir de los resultados obtenidos, se proponen acciones vinculadas con la gestión.
