Social intra-organizational connection: effects in three relational domains

Purpose – The purpose of this paper is to present the construct of social intra-organizational connection (SIC). This construct reflects the extent to which a focal actor believes his alters present behaviors of social inclusion in relation to himself. This assessment compares the ego’s expectations of being included and the behavior of inclusion performed by those alters with whom the actor has more frequent interactions. The effects of this construct are tested in the organizational domain regarding the intention to leave, in the domain of co-workers regarding cooperation and in the family domain regarding work–family conflict. Design/methodology/approach – The survey data were collected from 380 Brazilian workers. Findings – The results confirmed the effects of SIC in the relational domain of the organization through the variation in the focal actor’s intention to leave. In the sphere of coworkers, the effects of SIC were found in the variation of the degree of cooperation. In the family sphere, SIC had an influence upon the intensity of the work–family conflict. Originality/value – The research indicates that the behavior of making direct contacts and more frequent interactions by the focal actor extends to other relational spheres through the transitions of the organizational member between the domains of organization, coworkers and family. This paper draws attention to the need to consider the local networks, both within and beyond the organization, and their effects on each other

A memetic algorithm for logistics network design problems

Mestrado em Decisão Económica e EmpresarialNeste trabalho, um algoritmo memético é desenvolvido com o intuito de ser aplicado a uma rede logística, com três níveis, múltiplos períodos, seleção do meio de transporte e com recurso a outsourcing. O algoritmo memético pode ser aplicado a uma rede logística existente, no sentido de otimizar a sua configuração ou, se necessário, pode ser utilizado para criar uma rede logística de raiz. A produção pode ser internalizada e é permitido o envio direto de produtos para os clientes. Neste problema, as capacidades das diferentes infraestruturas podem ser expandidas ao longo do período temporal. Caso se trate uma infraestrutura já existente, após uma expansão, já não pode ser encerrada. Sempre que se abre uma nova infraestrutura, a mesma também não pode ser encerrada. A heurística é capaz de determinar o número e localizações das infraestrutura a operar, as capacidades e o fluxo de mercadoria na rede logística.This thesis describes a memetic algorithm applied to the design of a three-echelon logistics network over multiple periods with transportation mode selection and outsourcing. The memetic algorithm can be applied to an existing supply chain in order to obtain an optimized configuration or, if required, it can be used to define a new logistics network. In addition, production can be outsourced and direct shipments of products to customer zones are possible. In this problem, the capacity of an existing or new facility can be expanded over the time horizon. In this case, the facility cannot be closed. Existing facilities, once closed, cannot be reopened. New facilities cannot be closed, once opened. The heuristic is able to determine the number and locations of facilities (i.e. plants and warehouses), capacity levels as well as the flow of products throughout the supply chain

Análise das Díades para Compreender a Semelhança da Ação Estratégica : uma aplicação da Regressão Múltipla QAP (MRQAP)

O objetivo do artigo é analisar a utilização da Regressão Múltipla via Quadratic Assignment Procedure (QAP) para testar hipóteses sobre a semelhança no comportamento dos atores sociais utilizando medidas diádicas. Destaca-se que os dados empregados na aplicação da técnica figuram como exemplo das potencialidades e dificuldades no tratamento de dados relacionais. Discutem-se os diferentes níveis de análise da Análise de Redes Sociais (ARS) e como o nível da díade pode contribuir para as pesquisas em Ciências Sociais. O procedimento QAP para a avaliação da relação entre matrizes é discutido. Para se analisar a aplicação da técnica é apresentado um exemplo empírico utilizando dados de um survey realizada para obtenção de variáveis relacionais e dados de atributos que caracterizaram a interação entre sessenta pastores de congregações da Assembléia de Deus (AD) em Curitiba, Brasil. O resultado das análises permitiu as seguintes conclusões: (a) as transformações das variáveis é um processo simples, mas requer cuidados, pois parte dos procedimentos é decorrente do julgamento dos pesquisadores, o que pode influenciar o resultado da análise; e (b) por ser uma técnica pouco utilizada e ainda em avaliação quanto a sua robustez, sugere-se parcimônia e consideração dos limites na sua aplicação em investigações sociais.The main objective of this article is to analyze the use of Multiple Regression via Quadratic Assignment Procedure (QAP) in order to test the hypothesis about the similarity in the behavior of social actors by using dyadic measurements. The data used in the empirical analysis is just an example of the possibilities and limitations of the test. The different levels of analysis of the Social Network Analysis are discussed as well as how the dyadic level may contribute to the research in the field of Social Sciences. The QAP procedure to evaluate the relationship between matrices is presented as a solution to the dyadic data analysis. In order to analyze the application of the QAO technique, an empiric example is presented in which the data utilized was obtained from: a survey done in order to gather relational variables and from attributes that characterize the standards of interaction among sixty pastors from different Assembléia de Deus (AD) congregations in Curitiba, Brazil. The result of these analyses led to the following conclusions: a) Variable transformation is a simple process, but it requires care and attention, since part of the procedures is a result of the researchers' judgment, and therefore may influence the final result of said analysis; and b) because it is a technique seldom used and still under evaluation when its strength is considered, parsimony and limit consideration are suggested when applying the technique in social investigation

Social connection in organizations: the effects of local ties on job engagement and performance

Neste artigo, teve-se como objetivo examinar o efeito dos laços locais dos atores organizacionais em seu grau de engajamento e desempenho no trabalho. O estudo foi realizado por meio de um survey com 249 respondentes. O efeito dos laços locais (i.e., laços do ego) foi analisado por meio do grau de conexão social intraorganizacional. O engajamento foi mensurado nas dimensões física, cognitiva e emocional. O desempenho foi representado pelo grau de consecução das tarefas. Os resultados apontam que apenas o engajamento cognitivo e o desempenho são influenciados pelo grau de conexão social intraorganizacional. Tais resultados são explorados nas conclusões do artigo.This study examines the effect of local ties of organizational actors on their degree of job engagement and performance. The study carried out a survey with 249 respondents and analyzed the effect of local ties (i.e., ties of the ego) through degrees of intra-organizational social connections. Engagement was measured in physical, cognitive, and emotional dimensions. Performance was represented by the degree of achievement in tasks. The results show that only cognitive engagement and performance are influenced by degrees of intra-organizational social connection. These results are explored in the conclusions of the article.El objetivo del presente trabajo fue examinar el efecto de los vínculos locales de los actores organizacionales en su nivel de compromiso y rendimiento en el trabajo.

El compromiso fue medido en las dimensiones física, cognitiva y emocional, y el desempeño fue representado por el grado de cumplimiento de las tareas. Los resultados indican que sólo el compromiso cognitivo y el desempeño están influenciados por el grado de conexión social intraorganizacional. Se detallan estos resultados en las conclusiones del artículo

Ethics and Design in the Brazilian Context

Often driven by practical and immediate requirements, more and more people are incorporating technology into a variety of aspects of their lives, often without reflecting on the consequences of using them. On the other hand, studies on interactive system development that lead to behavioral change have been gaining ground on the agenda of large HCI conferences. This movement brings to the forefront the fundamental issues of ethics in design and technology use. A designer’s intentions, when directing certain actions or behaviors, are not always explicit or desired by the stakeholders affected by the use of the technology. Systems that induce an undesired purchase, or even those that use conditioning strategies to cause a behavioral change are examples of such intentions. The challenge proposed is therefore about the relationship between design and personal freedom in a way that these technology users do not become victims, either passively or submissively, of the effects of its use. This advance allows for the redefinition of the relationship between man and technology, and the application of new forms of designing and developing interactive systems that take into account the ethical aspects of this relationship

PROPOSING A METHOD TO CREATE METACOGNITIVE SCHOOL EXAMS

Metacognition is defined as the capacity of the persons to monitor, to regulate and to construct knowledge about their inner processes. Theoretically, this construct is relevant to Education and correlated areas, since the process of learning and knowledge construction involves metacognition. Besides, there are evidences that certain metacognitive components are predictors of academic achievement of the students. Regarding these aspects, this paper proposes a methodology that permits educators to elaborate metacognitive school exams, which are capable of measuring both the students' knowledge of an educational domain (i.e., concepts pertaining to biology, chemistry, history, mathematics, physics, and so on), and the following metacognitive abilities: feeling-of-knowing, monitoring (detection of errors), self-management, and judgment. In this paper, we present the methodology stressing on the steps that enable the teacher to elaborate a school exam capable of measuring a target educational domain, as well as the stated metacognitive abilities. Concomitantly, we apply this methodology, showing the construction of the Metacognitive School Exam in Electrostatics.  Article visualizations
