Experimental trade-offs between different strategies for multihop communications evaluated over real deployments of wireless sensor network for envir…

2018

Although much work has been done since wireless sensor networks appeared, there is not a great deal of information available on real deployments that incorporate basic features associated with these networks, in particular multihop routing and long lifetimes features. In this article, an environmental monitoring application (Internet of Things oriented) is described, where temperature and relative humidity samples are taken by each mote at a rate of 2 samples/min and sent to a sink using multihop routing. Our goal is to analyse the different strategies to gather the information from the different motes in this context. The trade-offs between ‘sending always’ and ‘buffering locally’ approac…

Underwater Wireless Communications for Cooperative Robotics with UWSim-NET

2019

The increasing number of autonomous underwater vehicles (AUVs) cooperating in underwater operations has motivated the use of wireless communications. Their modeling can minimize the impact of their limited performance in real-time robotic interventions. However, robotic frameworks hardly ever consider the communications, and network simulators are not suitable for HIL experiments. In this work, the UWSim-NET is presented, an open source tool to simulate the impact of communications in underwater robotics. It gathers the benefits of NS3 in modeling communication networks with those of the underwater robot simulator (UWSim) and the robot operating system (ROS) in modeling robotic systems. Thi…

Optimism and sense of coherence in mothers and fathers of children with cerebral palsy participating in an intensified habilitation programme

2015

Background: To describe optimism and sense of coherence in mothers and fathers of preschool children with cerebral palsy (CP), before and after participation in an intensified habilitation program. Methods: Forty-five parents of preschool children with CP answered the Life Orientation Test (LOT) and sense of coherence questionnaire (SOC) twice during one year. Results: Parents of the youngest CP children and those with high stress levels reported reduced optimism and sense of coherence at baseline. No statistically significant changes in LOT and SOC scores were found during the programme period. However, among mothers who reported clinically significant change, 67% reported more optimism af…

The acrobatics of dying: A psychodynamic framework for palliative care

2017

This article aims at summing up the reflections of a small group of psychologists who work in the domain of palliative treatment. The theory and methodology supporting it are borrowed by a group analysis approach; the group's purpose is a research based on the workers' experience elaboration, which aims at finding out both the specificities of the work apparatus with the people accompanied to the conclusion of their lives, and the main thematic areas of the relationship between healthcare team, patients, and families. The work we present aims at introducing the most meaningful themes that emerged during group meetings: first of all, some service criticalities examined in the area of termina…

Premis, càstigs i educació

2008

Els autors defensen que el costum i la llei confi guren la legalitat i la moralitat socials i determinen el nostre comportament, alhora que qüestionen els resultats 'esperats' de l'aplicació mecànica dels premis i càstigs en educació. Distingeixen el control extern 'supervisió' i l'intern 'motivació' en l'esdevenir dels comportaments analitzats, en relació a l'aplicació d'aquelles sancions i tot seguit aborden l'estudi monogràfi c des del conductisme, des del cognitivisme i des de la perspectiva moral. Ara aborden la complexitat contextual de la intervenció pedagògica i les alternatives possibles des dels plantejaments actitudinals dels subjectes, per concloure que els premis tenen la fi na…

Problemas multiplicativos relacionados con la división de fracciones : un estudio sobre su enseñanza y aprendizaje

2013

Los estudiantes tienen dificultades para asociar el enunciado de un problema multiplicativo con la operación que permite resolverlo; esta investigación identifica los tipos de problemas multiplicativos que los estudiantes reconocen como de división de fracciones. Mediante el análisis histórico-epistemológico de textos de enseñanza sobre tres épocas históricas y ocho períodos diferentes, se obtiene un listado de variables de enseñanza (algoritmos, sentidos de uso de fracción y de división de fracciones, representaciones, problemas), así como los valores de dichas variables. Se localizan en los textos consultados algunas reglas particulares y seis algoritmos generales, cuyo predominio ha vari…

Ricerche in tema di società questuarie

2019

Intorno al regime delle società di tipo questuario – riconducibili agli schemi teorici della societas universorum quae ex quaestu veniunt – e delle società unius alicuius negotiationis e unius rei, si profusero gli sforzi interpretativi dei giuristi romani, fin dalla fine dell’età repubblicana. La monografia scientifica ripercorre le tracce della individuazione della nozione stessa di quaestus (guadagno), con particolare riferimento alla inclusione al suo interno delle donazioni cd. remuneratorie; ancora, ricostruisce il dibattito giurisprudenziale sorto intorno alla questione se i soci – nella determinazione delle quote – dovessero rispettare una proporzione rispetto ai conferimenti, con u…

2021

Functional proprioceptive information is required to allow an individual to interact with the environment effectively for everyday activities such as locomotion and object manipulation. Specifically, research suggests that application of compression garments could improve proprioceptive regulation of action by enhancing sensorimotor system noise in individuals of different ages and capacities. However, limited research has been conducted with samples of elderly people thus far. This study aimed to examine acute effects of wearing knee-length socks (KLS) of various compression levels on ankle joint position sense in community-dwelling, older adults. A total of 26 participants (12 male and 14…

Sense of coherence, academic performance and professional vocation in Certified Nursing Assistant students

2019

BACKGROUND: The sense of coherence (SOC) of the salutogenic health model explains why people in stressful situations are able to maintain or even improve their health. There are some studies on which measures are more effective to reduce stress in Nursing assistant students. There are no studies that link SOC with the two key aspects in the prevention of stress in Nursing assistant students: the motivation of pursuing this profession and the academic level. OBJECTIVES: To explore the salutogenic paradigm among Nursing assistant students in a region of Spain (Comunitat Valenciana). DESIGN: Cross-sectional, analytical and exploratory study carried out in 2016. METHODS: Students of the first y…

Preattentive and attentive responses to changes in small numerosities of tones in adult humans

2016

The brain hosts a primitive number sense to non-symbolically represent numerosities of objects or events. Small exact numerosities (~4 or less) can be individuated in parallel. In contrast, large numerosities (more than ~4) can only be approximated. However, whether small numerosities can be approximated without their parallel individuation remains unclear. Parallel individuation is suggested to be an attentive process and numerical approximation an automatic process. We, therefore, tested whether small numerosities can be represented preattentively. We recorded adult humans׳ event-related potentials (ERPs) and behavioral responses to 300-ms sequences of six tones (each of either 440 Hz or …
