A novel identification method for generalized T-S fuzzy systems
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/893807 In order to approximate any nonlinear system, not just affine nonlinear systems, generalized T-S fuzzy systems, where the control variables and the state variables, are all premise variables are introduced in the paper. Firstly, fuzzy spaces and rules were determined by using ant colony algorithm. Secondly, the state-space model parameters are identified by using genetic algorithm. The simulation results show the effectiveness of the proposed algorithm
Supply chain coordination under asymmetric information and partial vertical integration
2022
AbstractSupply chain contracting is known to suffer from inefficiency in the presence of asymmetric information. Full vertical integration would eliminate the informational inefficiency but can be strategically undesirable. Yet today’s supply chain partnerships exhibit a certain degree of partial vertical integration via equity ties between the firms. Such governance forms received limited attention in supply chain research. Management literature suggests that partial vertical integration may help the firms to ease contracting problems by aligning their incentives, and thus improve the total surplus. We address this proposition by studying a model of a partially integrated supply chain in w…
A Mathematical Model for Equitable In-country COVID-19 Vaccine Allocation
2022
Given the scarcity of COVID-19 vaccines, equitable (fair) allocation of limited vaccines across the main administrative units of a country (e.g. municipalities) has been an important concern for public health authorities worldwide. In this study, we address the equitable allocation of the COVID-19 vaccines inside countries by developing a novel, evidence-based mathematical model that accounts for multiple priority groups (e.g. elderly, healthcare workers), multiple vaccine types, and regional characteristics (e.g. storage capacities, infection risk levels). Our research contributes to the literature by developing and validating a model that proposes equitable vaccine allocation alternatives…

An active inference and epistemic value view of metacognition
2015
Metacognition concerns our monitoring and control of mental operations (knowing what you know). Much thinking about metacognition is liable to fall foul of the classic homunculus problem: Nobody can specify who or what does the "metacognition." We describe how the Active Inference and Epistemic Value (AIEV) model offers an operationalization of epistemic behaviors which can explain two example metacognitive phenomena: Control and monitoring of word learning, and the search for unretrieved information in the feeling of knowing. Curiosity drives a search forward, but it is held in check by considering the utility of what is retrieved from memory.
Racism and ethics in the globalized business world
2002
This paper analyzes the concept of racism in the context of business ethics and globalization. It first introduces three ethical traditions to understand moral issues in business: deontological, utilitarian and virtue ethics. Then it discusses about the challenges and demands that globalization has set to multicultural and multinational business operations. Third, it clarifies how racism works when it is understood as an ideology‐based phenomenon. It argues that there is a great value of knowing how racism works for the development of an anti‐racist and nondiscriminating organization. Although any of the three traditions on ethical thinking does not give direct answer to the question of how…
Antecedents of team turnover intentions in temporary organizations
2016
Purpose – The purpose of this paper is to shed light on the antecedents of team turnover intentions in temporary organizations such as projects, programs, or temporary teams. Design/methodology/approach – The authors systematically combine the findings from the literature on the antecedents of turnover intentions in permanent organizations (PO) with the characteristics of temporary organizations (TO) and develop a research model comprising personal factors, job-related factors, and organization-related factors. Findings – A research model consisting of testable propositions that the authors derived from both specificities of TO and the antecedents of turnover intentions in PO. Originality/…
Work team effectiveness in organizational contexts
2005
PurposeThis introductory paper aims to provide a contextualization of recent research and applications on work team effectiveness in organizational contexts carried out in Spain and Portugal and to describe connections between this research and the main trends in the international scene.Design/methodology/approachSince the 1990s, new occupational and organizational realities have deepened scientific interest in work teams in both Spain and Portugal. A range of recently published (1992‐2004) works in this area are reviewed. The selected sources are papers published in Spanish, Portuguese and international journals.FindingsReviewing this work, four major trends are identified that synthesize …
Entrepreneurial success and human resources
2011
PurposeThis paper aims to determine factors that have an influence on human resource management and entrepreneurial success in the context of European innovative small and medium‐sized enterprises (SMEs).Design/methodology/approachA primary test questionnaire was tested with 50 Spanish entrepreneurs. The feedback from this study was used to improve the survey for a final test. Multivariate regression analysis was used to differentiate the factors that allow the explanation of the variables to be studied and factors that, a priori, seem to be the most relevant in explaining entrepreneurial success.FindingsThe study allows the determination of what factors make the European entrepreneur succe…
Daily deliberative dissonance acting among police officers.
2014
Purpose – The purpose of this paper is to gain insight into the relationships of daily deliberative dissonance acting (DDA) with daily strain and daily work engagement. DDA refers to the deliberate acting of emotions to achieve one's work goals. The authors hypothesized that daily DDA would be positively related to strain through feelings of emotional dissonance. In addition, the authors predicted that DDA would be positively related to daily work engagement via job accomplishment. Design/methodology/approach –The authors applied a five-day quantitative diary design with two measurement occasions per day using a sample of 54 police officers (i.e. 270 measurement occasions). In the multilev…
