Application of machine learning algorithms in thermal images for an automatic classification of lumbar sympathetic blocks

2023

Purpose There are no previous studies developing machine learning algorithms in the classification of lumbar sympathetic blocks (LSBs) performance using infrared thermography data. The objective was to assess the performance of different machine learning algorithms to classify LSBs carried out in patients diagnosed with lower limbs Complex Regional Pain Syndrome as successful or failed based on the evaluation of thermal predictors. Methods 66 LSBs previously performed and classified by the medical team were evaluated in 24 patients. 11 regions of interest on each plantar foot were selected within the thermal images acquired in the clinical setting. From every region of interest, different t…

Between-group competition and human cooperation.

2008

A distinctive feature of human behaviour is the widespread occurrence of cooperation among unrelated individuals. Explaining the maintenance of costly within-group cooperation is a challenge because the incentive to free ride on the efforts of other group members is expected to lead to decay of cooperation. However, the costs of cooperation can be diminished or overcome when there is competition at a higher level of organizational hierarchy. Here we show that competition between groups resolves the paradigmatic ‘public goods’ social dilemma and increases within-group cooperation and overall productivity. Further, group competition intensifies the moral emotions of anger and guilt associated…

A idealização dose espaços rurais no ensino médio. Um estudo de representações sociais

2021

Resumen La teoría de las representaciones sociales contribuye a conocer los discursos que influyen en la vida de las personas y cómo los sujetos reproducen esos conocimientos para interpretar el mundo. El conocimiento que nos interesa en esta investigación es la cosmovisión que los estudiantes de 3.° de Educación Secundaria Obligatoria (ESO) y de 2.° de bachillerato de la provincia de Valencia (España) tienen acerca de los espacios rurales. Dicha cosmovisión proviene de diferentes fuentes y contextos de información, por lo que la aplicación de las representaciones sociales al campo de la didáctica de la geografía es pertinente en este estudio. En concreto, el enfoque fenomenológico de la Ge…

“Without social there is no health”: Social work perspectives in multidisciplinary healthcare

2022

The pandemic has not just affected the health sphere: strong social effects of the emergency have added to the health risk, stressing on social relations and the deterioration of people's living conditions, and making those who are already fragile more fragile. Notwithstanding, during the emergency following the COVID-19 pandemic the attention was focused, indeed understandably, on the health aspects, widening the already existing misalignment between the health interventions and the social ones. Emergency oriented efforts and resources more toward a clinical care approach (cure) than toward support for the social and the inclusion aspects (care). Reflecting on the specific area of health c…

A bibliometric analysis of cultural heritage research in the humanities: The Web of Science as a tool of knowledge management

2023

AbstractSubstantial research on the topic of cultural heritage has been conducted over the past two decades. At the same time, the overall output volume of journals and citation metrics have become important parameters in assessing and ranking researchers’ performance. Even though the scholarly interest in cultural heritage has recently increased world-wide, a comprehensive analysis of the publication output volume and its correlation to the shift in the cultural heritage regime starting in 2003 is still lacking. The article aims to understand the role of Web of Science (WOS) as a tool of knowledge management in academia by drawing on the scholarly output volume, the patterns displayed by t…

The Role of Social Media in the Creation of Young People’s Consumer Identities

2023

This article explores how young people construct and express their consumer identities via their consumption styles on social media. The importance of commercial content on social media, such as the postings of social media influencers and advertisers, has been increasing during the past years. Framed by theories on social identity, social comparison and consumer socialization, we analysed focus group discussions with 15 to 19-year-old teenagers in Finland ( N = 35). The results reveal that the participants had a clear understanding of their consumer identities: what kind of consumers they were and what they did not want to be. The consumption styles: luxury brand-oriented, trendy second-h…

Relaciones suelo-vegetación en una toposecuencia del Escudo Guayanés, Venezuela

2014

El Escudo Guayanés es uno de los territorios más antiguos del planeta; tiene millones de años sometido a procesos de lixiviación y erosión que dejan suelos oligotróficos. El objetivo de este trabajo fue hacer la caracterización de los parámetros físicos y químicos de los suelos, en diferentes comunidades boscosas de la Reserva Forestal Imataca, e identificar ciertas relaciones entre los componentes edáficos y las especies que allí se presentan. Se realizó un inventario de todos los individuos mayores a 10cm dap (diámetro a la altura del pecho) en 15 parcelas (1ha); en cada una de esas parcelas se evaluaron cuatro sub-parcelas de sotobosque (100m²) para contabilizar todas las espermatofitas;…

Role of trust in cross-cultural adaptation : the perspective of international degree students at a Finnish university

Biological adaptation in light of the Lewontin–Williams (a)symmetry

2022

Neo-Darwinism characterises biological adaptation as a one-sided process, in which organisms adapt to their environment but not vice versa. This asymmetric relationship – here called Williams’ asymmetry – is called into question by Niche Construction Theory, which emphasises that organisms and their environments often mutually affect each other. Here we clarify that Williams’ asymmetry is specifically concerned with (quasi-) directed modifications towards phenotypes that increase individual fitness. This directedness – which drives the adaptive fit between organism and environment – entails far more than the mere presence of cause-effect relationships. We argue that difficulties with invoki…

Stakeholder salience for small businesses : a social proximity perspective

2017

This paper advances stakeholder salience theory from the viewpoint of small businesses. It is argued that the stakeholder salience process for small businesses is influenced by their local embeddedness, captured by the idea of social proximity, and characterised by multiple relationships that the owner-manager and stakeholders share beyond the business context. It is further stated that the ethics of care is a valuable ethical lens through which to understand social proximity in small businesses. The contribution of the study conceptualises how the perceived social proximity between local stakeholders and small business owner-managers influences managerial considerations of the legitimacy, …
