Sociological and philosophical aspects of human interaction with technology: advancing concepts

It is not possible to imagine our lives today without technology. From the moment we get up in the morning until the time that we go to bed at night, technology is present in almost every moment, even if we are not aware of it. Some of the most basic activities we need to perform regularly could not be carried out without technology. Sociological and Philosophical Aspects of Human Interaction with Technology: Advancing Concepts presents a careful blend of conceptual, theoretical and applied research in regards to the relationship between technology and humans. This book explores the importance of these interactions, aspects related with trust, communication, data protection, usability concerning organizational change, and e-learning. The advancement of these theories and practices will benefit from this publication as it provides a voice for the users.

Self-optimization aspects for dynamic scheduling

Scheduling is a critical function that is present throughout many industries and applications. A great need exists for developing scheduling approaches that can be applied to a number of different scheduling problems with significant impact on performance of business organizations. A challenge is emerging in the design of scheduling support systems for manufacturing environments where dynamic adaptation and optimization become increasingly important. At this scenario, self-optimizing arise as the ability of the agent to monitor its state and performance and proactively tune itself to respond to environmental stimuli.

Preval��ncia e impacte da incontin��ncia urin��ria e stresse. Antes e durante a gravidez

Introdu����o: A Incontin��ncia Urin��ria (IU) feminina �� um importante problema de sa��de p��blica, quer pela sua elevada preval��ncia, quer pelo elevado impacte f��sico, ps��quico e social na vida da mulher. O objectivo deste estudo foi determinar a preval��ncia, o impacte da Incontin��ncia Urin��ria de Stresse (IUS) antes e durante a gravidez em parturientes do distrito de Viana do Castelo e determinar a percentagem de mulheres que procura apoio de um profissional de sa��de para o seu problema. M��todo: Realizou-se um estudo transversal considerando uma amostra representativa do distrito, constitu��da por 336 mulheres, cujo parto ocorreu no Hospital de Santa Luzia, no per��odo compreendido entre 15 de Janeiro a 29 de Mar��o de 2002. Todas as mulheres foram submetidas a um question��rio no p��s-parto hospitalar. Resultados: A preval��ncia da IUS, definida como Alguma vez teve perda de urina durante a realiza����o de um esfor��o? foi de 5,4% (IC 95%: 3,0-7,8) antes da gravidez e 51,5% (IC 95%: 46,1-56,9) durante a gravidez actual. Os factores associados �� ocorr��ncia da IUS antes da gravidez foram a multiparidade (OR=9,96), a presen��a de diabetes (OR=4,61) e obesidade (OR=4,76), e �� IUS durante a gravidez foram a multiparidade (OR=1,66), a diabetes (OR=2,62) e a obstipa����o (OR=1,73). A grande maioria (88,9%) das mulheres com IUS sente-se incomodada por se sentir h��mida, 48,5% sente-se nervosa ou ansiosa e 57,3% tem medo que os outros se apercebam do odor. Durante a gravidez, apenas menos de metade das mulheres que tiveram perdas de urina procurou apoio de um profissional de sa��de, apesar de a maioria ter interesse em tratar o problema. Conclus��es: A IUS afecta um grande n��mero de mulheres deste distrito antes e durante a gravidez. A IUS tem reflexos em v��rias dimens��es da sa��de, sendo o bem-estar f��sico e emocional os mais afectados, mas apenas uma pequena percentagem de mulheres revela o seu problema de IUS a um profissional de sa��de. Perante esta evid��ncia tornase importante que os profissionais de sa��de conhe��am esta realidade e se preocupem em dar resposta a estes problemas de sa��de.

ABS4GD: a multi-agent system that simulates group decision processes considering emotional and argumentative aspects

Emotion although being an important factor in our every day life it is many times forgotten in the development of systems to be used by persons. In this work we present an architecture for a ubiquitous group decision support system able to support persons in group decision processes. The system considers the emotional factors of the intervenient participants, as well as the argumentation between them. Particular attention will be taken to one of components of this system: the multi-agent simulator, modeling the human participants, considering emotional characteristics, and allowing the exchanges of hypothetic arguments among the participants.

LAID - a smart decision room with ambient intelligence for group decision making and argumentation support considering emotional aspects

Decision Making is one of the most important activities of the human being. Nowadays decisions imply to consider many different points of view, so decisions are commonly taken by formal or informal groups of persons. Groups exchange ideas or engage in a process of argumentation and counter-argumentation, negotiate, cooperate, collaborate or even discuss techniques and/or methodologies for problem solving. Group Decision Making is a social activity in which the discussion and results consider a combination of rational and emotional aspects. In this paper we will present a Smart Decision Room, LAID (Laboratory of Ambient Intelligence for Decision Making). In LAID environment it is provided the support to meeting room participants in the argumentation and decision making processes, combining rational and emotional aspects.

Ecotoxicological aspects related to the presence of pharmaceuticals in the aquatic environment

Pharmaceuticals are biologically active and persistent substances which have been recognized as a continuing threat to environmental stability. Chronic ecotoxicity data as well as information on the current distribution levels in different environmental compartments continue to be sparse and are focused on those therapeutic classes that are more frequently prescribed and consumed. Nevertheless, they indicate the negative impact that these chemical contaminants may have on living organisms, ecosystems and ultimately, public health. This article reviews the different contamination sources as well as fate and both acute and chronic effects on non-target organisms. An extensive review of existing data in the form of tables, encompassing many therapeutic classes is presented.

Mathematical aspects of the Heisenberg uncertainty principle within local fractional Fourier analysis

In this paper, we discuss the mathematical aspects of the Heisenberg uncertainty principle within local fractional Fourier analysis. The Schr��dinger equation and Heisenberg uncertainty principles are structured within local fractional operators.

Practical aspects of slot-based task- splitting dispatching in its schedulability analysis

Consider the problem of scheduling a set of sporadic tasks on a multiprocessor system to meet deadlines using a tasksplitting scheduling algorithm. Task-splitting (also called semipartitioning) scheduling algorithms assign most tasks to just one processor but a few tasks are assigned to two or more processors, and they are dispatched in a way that ensures that a task never executes on two or more processors simultaneously. A certain type of task-splitting algorithms, called slot-based task-splitting, is of particular interest because of its ability to schedule tasks at high processor utilizations. We present a new schedulability analysis for slot-based task-splitting scheduling algorithms that takes the overhead into account and also a new task assignment algorithm.

Evolution of the application and database with aspects

Generally, the evolution process of applications has impact on their underlining data models, thus becoming a time-consuming problem for programmers and database administrators. In this paper we address this problem within an aspect-oriented approach, which is based on a meta-model for orthogonal persistent programming systems. Applying reflection techniques, our meta-model aims to be simpler than its competitors. Furthermore, it enables database multi-version schemas. We also discuss two case studies in order to demonstrate the advantages of our approach.

Engineering Temporal and Spatial Aspects in OWL using Patterns

WWW is a huge, open, heterogeneous system, however its contents data is mainly human oriented. The Semantic Web needs to assure that data is readable and ���understandable��� to intelligent software agents, though the use of explicit and formal semantics. Ontologies constitute a privileged artifact for capturing the semantic of the WWW data. Temporal and spatial dimensions are transversal to the generality of knowledge domains and therefore are fundamental for the reasoning process of software agents. Representing temporal/spatial evolution of concepts and their relations in OWL (W3C standard for ontologies) it is not straightforward. Although proposed several strategies to tackle this problem but there is still no formal and standard approach. This work main goal consists of development of methods/tools to support the engineering of temporal and spatial aspects in intelligent systems through the use of OWL ontologies. An existing method for ontology engineering, Fonte was used as framework for the development of this work. As main contributions of this work Fonte was re-engineered in order to: i) support the spatial dimension; ii) work with OWL Ontologies; iii) and support the application of Ontology Design Patterns. Finally, the capabilities of the proposed approach were demonstrated by engineering time and space in a demo ontology about football.

O contrato psicol��gico na expatria����o

Nos ��ltimos anos, o n��mero de expatriados tem apresentado uma tend��ncia de crescimento a n��vel mundial. Desta forma, a gest��o de expatriados, que integra o subsistema da gest��o internacional de recursos humanos, passa a ter uma aten����o renovada e tem vindo a crescer enquanto ��rea de interven����o de gest��o de recursos humanos. Por sua vez, o contrato psicol��gico tem sido visto, cada vez mais, como um fator relevante na explica����o das rela����es laborais e o n��mero de estudos em torno desta tem��tica tem aumentado. O sucesso da expatria����o �� diretamente influenciado pelo contrato psicol��gico e depende, em grande parte, da forma como s��o desenvolvidas as pr��ticas de GRH (Homem & Tolfo, 2008). Desta forma, �� essencial compreender a rea����o dos trabalhadores perante a mudan��a (Bligh & Carsten, 2005; Shield, Thorpe, & Nelson, 2002), uma vez que o comportamento de resposta aos mesmos pode ser um contributo para marcar a diferen��a decisiva entre o sucesso ou o fracasso da miss��o internacional. Neste mesmo contexto, assiste-se a uma crescente aten����o sobre o contributo que o Contrato Psicol��gico pode ter em contextos de incerteza. O individuo, enquanto trabalhador de uma organiza����o que decide aceitar uma miss��o internacional e ir viver para outro pa��s, tem necessidade de se enquadrar num relacionamento cont��nuo e motivador com a entidade empregadora. A no����o do contrato psicol��gico torna-se fundamental para o entendimento das rela����es de trabalho, a partir das perce����es das pessoas envolvidas. Muitos dos aspetos destes relacionamentos s��o impl��citos (n��o escritos) o que pode provocar diferentes interpreta����es sobre as expectativas, promessas e obriga����es entre partes. V��rios autores defendem que o contrato psicol��gico �� um meio fundamental na compreens��o e gest��o das atitudes e comportamentos dos indiv��duos nas organiza����es (Bunderson, 2001; Kraimer, Wayne, Liden, & Sparrow, 2005; Lemire & Rouillard, 2005). O objetivo deste trabalho �� conhecer o estado do contrato psicol��gico nos expatriados: antes da miss��o, ap��s a fase de adapta����o ao pa��s de destino e na repatria����o. Foi utilizada a metodologia qualitativa e para tal, foi aplicada uma entrevista individual semiestruturada e um question��rio sociogr��fico ��s pessoas que se encontravam, �� data, expatriadas. No total foram realizadas dez entrevistas e a an��lise das entrevistas foi efetuada atrav��s da Grounded Theory. Os resultados sugerem que h�� apenas cumprimento do contrato psicol��gico na fase da prepara����o da miss��o internacional, havendo, por outro lado, incumprimento do contrato psicol��gico durante a expatria����o e na repatria����o, de acordo com a perce����o que os expatriados t��m acerca do fim da expatria����o. No entanto, a maioria dos expatriados entrevistados avalia positivamente a experi��ncia da expatria����o, apesar de as organiza����es parecerem ter apenas algumas regras estabelecidas de suporte ao expatriado, nomeadamente suporte log��stico e financeiro, e n��o disporem de um programa completo e aprofundado de suporte �� gest��o da expatria����o. Os resultados sugerem ainda que �� essencial que as organiza����es estimulem a comunica����o com os expatriados e fomentem o suporte que deve ser constante e intr��nseco a todas as fases da expatria����o, a fim de evitar a sensa����o de ���abandono���.
