TRUST IN SUPERIORS AND DYSFUNCTIONAL BEHAVIORS : AN EXPERIMENTAL STUDY ON BUDGETARY SLACK

Purpose: This paper analyzes trust in superiors as an informal control mechanism to reduce budgetary slack. We examine how relationships between trust of subordinates in their superiors and economic incentive reduce the tendency of subordinates to create budgetary slack.Methodology: An experiment was designed with participants who play the role of manager or executive alternativelyFindings: Results show that the introduction of an economic incentive does not affect the relationship between trust and budgetary slack.Implications/limitations: This study will let organizations to further the budgeting process by using informal mechanism, such as trust, as a complement to traditional mechanism (e.g. monetary/ economic incentives). This enhances the effectiveness of the organization’s actions and policies. Originality/Value: The findings of this study complement the results of previous studies on how trust is related to financial and non-financial performance criteria

Avaliação do desempenho de leitos flutuantes de macrófitas (Vetiveria zizanioides e Phragmites australis) na remoção de metais pesados da água da Ribeira de Água Forte (Aljustrel, Sul de Portugal)

A área envolvente da sub-bacia da Ribeira do Roxo (bacia hidrográfica do Rio Sado), dispõe de troços completamente estéreis, pondo em causa a produtividade das atividades agrícolas aí praticadas. Tal, poderá ser devido, para alem de outros fatores, à afluência da Ribeira de Água Forte, que apresenta características de Drenagem Mineira Ácida (DMA). Considera-se, assim, pertinente a resolução deste problema, recorrendo a soluções eficazes e ambientalmente sustentáveis. O objetivo deste estudo foi testar a eficiência de remoção de metais pesados da água da Ribeira de Água Forte utilizando a tecnologia de Leitos Flutuantes (LFs) de macrófitas (Vetiveria zizanioides e Phragmites australis), em instalação piloto, monitorizando e avaliando a qualidade da água e o desempenho das mesmas. Foram construídos dois leitos, cada um contendo um tipo de macrófita e água proveniente da Ribeira de Água Forte, monitorizando-se a sua evolução durante 6 meses. Obtiveram-se taxas médias de remoção dos metais pesados na água do LF da Vetiveria zizanioides e do LF da Phragmites australis, de Fe=40%; Zn=25%; Cu=15%; Mn=14% e Fe=27%; Zn=17%; Mn=16%; Cu=6%; respetivamente. A ordem de acumulação de metais pesados na biomassa total da Vetiveria zizanioides foi de Fe>Zn>Cu>Mn e na Phragmites australis foi de Fe>Zn>Mn>Cu. O crescimento da Vetiveria zizanioides e Phragmites australis na biomassa foliar foi de 7,1 ± 0,3 cm/mês e 2,5 ± 0,0 cm/mês e na biomassa radicular 3,8 ± 0,1 cm/mês e 4,1 ± 0,2 cm/mês, respetivamente. O crescimento das macrófitas evidenciaram capacidade de sobrevivência neste tipo de meio sem a ocorrência de dano severo na sua morfologia externa e anatómica, embora com alguma inibição do crescimento. Os resultados sugerem que a tecnologia de leitos flutuantes pode ser uma alternativa ambientalmente sustentável, permitindo a remoção de metais pesados a longo prazo

Comparison of skull growth in two ecosystem modifiers: beavers Castor canadensis (Rodentia: Castoridae) and muskrats Ondatra zibethicus (Rodentia: Cricetidae)

Beavers and muskrats are semi-aquatic, generalist herbivorous rodents regarded as invasive in southern South America, with high impacts on the ecosystem. They share some morphological characters of the skull, but different body sizes and phylogenetic history, showing evident shape differences in young and adult skulls during the development in both species. Considering their similar ecological specializations, skull shape could be achieved through different or similar patterns of allometric growth during ontogeny. We analyzed quantitatively the ontogenetic series including 94 specimens of beavers and muskrats and performed multivariate and bivariate analyses considering 20 linear measurements. Our main results from the different approaches suggest high differences in the ontogenetic trajectories of beavers and muskrats, implying disparity in the muscular, functional, and structural conditions of the skull of both species. These differences reflect that although skulls might undergo similar mechanical stress, it is possible to reach a cranial morphology compatible with the similar behavioral and ecological specializations between both species from patterns of skull development that are markedly different.Fil: Segura Gago, Alda Valentina.

Smart cities’ development in Spain: a comparison of technical and social indicators with reference to european cities

The evolution of the Spanish cities towards their digital transformation, integration of the Internet of Things (IoT), and improvement of social cohesion have been promoted by the government. However, this evolution has not yet been evaluated, and this assessment is considerably relevant as more than 200 M€ has been spent from the European Regional Development Fund (ERDF) through five calls divided into two national plans (2014–2020). In this evaluation, the projects of 61 beneficiary local entities have been analysed. The lines of action executed have been identified and compared, using standardised indicators, with the actions conducted in the European metropolis that are smart city references. The actions planned in the last call (Smart Territories National Plan) closely resemble the philosophy of the latest generation paradigm of smart cities (holistic approach and specialisation in topics such as tourism or intelligent buildings) from the initial point where the areas of technology, software, and governance were focused. This work offers a precise picture of the priorities and lines of the progress of smart cities at each period of the last decade and helps technicians and investigators evaluate executed projects and design new lines of development

Utilização colaborativa de representações multimédia no ensino: um estudo de investigação-ação com professores de física e química

Este estudo foi realizado no contexto de uma ação de formação subordinada ao tema das representações multimédia e destinada a professores de física e química de uma escola secundária. A ação, dinamizada pelo investigador e com a duração de seis meses, foi realizada na forma de Círculo de Estudos, durante o qual se procurou promover o trabalho colaborativo entre os dez professores participantes, todos eles integrando, tal como o investigador, o grupo de física e química da escola em referência. Como opção metodológica de base foi adotada uma estratégia de investigação-ação, configurando uma pesquisa de natureza qualitativa. A coexistência de diversas técnicas de recolha de dados, como entrevistas individuais, observação naturalista, conversas informais e análise documental, permitiu o recurso a procedimentos de triangulação metodológica na condução da análise de conteúdo que deu corpo aos resultados do estudo. A evidência recolhida sugere que o modelo de formação testado parece possuir, embora com naturais condicionantes, os requisitos necessários para promover o desenvolvimento do conhecimento técnico-pedagógico do conteúdo nos professores, estimulando a adoção de práticas colaborativas na utilização didática de representações multimédia; ABSTRACT: This study was performed in the training program framework of multimedia representation and it was intented for teachers of physics and chemistry of a secondary school. The training action, with six months duration, was conducted by the investigator and it was held in the form of Study Circle. During this program the investigator sought to promote collaborative work among the ten participating teachers, all of them, including the researcher, integrating the physics and chemistry group in that school. An action research strategy was adopted as a basic methodological option thus setting a qualitative research. The coexistence of different data collection techniques such as interviews, naturalistic observation, informal conversations and document analysis, allowed the use of methodological triangulation procedures in content analysis, which gave body to the study results. The evidence collected suggests that the tested training model seems to have, although with natural constraints, the necessary requirements to endorse the development of technological pedagogical content knowledge in teachers, stimulating the adoption of collaborative practices in the didactic use of multimedia representations

Stakeholders’ perceptions of new digital energy management platform in municipality of Loulé, Southern Portugal: a SWOT-AHP analysis

This study aimed to develop a multi-stakeholder analysis to identify the best strategies for the integration of a new Digital Energy Management Platform (DEMP). The municipality of Loulé (South of Portugal) was used as a case study. A Strengths, Weaknesses, Opportunities, and Threats (SWOT) framework combined with an Analytical Hierarchy Process (AHP) framework and a TOWS Matrix was employed to analyse the stakeholder’s perceptions to propose strategies for integrating the DEMP. Five focus stakeholder groups were involved. Results showed that stakeholders considered that the positive aspects of DEMP outweigh the negative aspects by approximately 36%. Strengths were ranked with 34.4%, Opportunities with 33.8%, Weaknesses with 20.2%, and Threats with 11.6%. The sequence of factors with the highest overall score by stakeholders was O1(12.7%) > S2(11.1%) > W2(7.4%) > T3(4.1%). Based on stakeholder perceptions, the most suitable strategies were those that use Strengths and Opportunities of the system (SO strategies), and strategies that take advantage of Opportunities while dealing with Weaknesses (WO strategies), achieving a prevalence compared with the other strategies of 34% and 27%, respectively. Therefore, the participation process involving stakeholders’ groups in the implementation and monitoring of the DEMP provided an action plan and consensus capable of meeting the environmental and municipal energy management challenges.info:eu-repo/semantics/publishedVersio

Los MOOC y su papel en la creación de comunidades de aprendizaje y participación

Despite its increasing popularity, the most promising value of MOOCs is not derived from what they are, but from what they may transform into, that is, the positive derivatives that have already started to flourish and are very much related to the open and flexible character of learning advocated by MOOCs (Yuan and Powell, 2013). These capabilities arise from their very nature, namely the modularity, scalability and (re) combinable nature, thus enabling the transition towards personalised learning pathways that are also more adjusted to individual competences and preferences. This is the rationale underlying the concept of learning and participation communities highlighted in this article by CSEV and underpinned by the creation of a new “umbrella” platform that brings together initiatives already implemented (like UnX) and new ones that are now being incorporated.Pese a su creciente popularidad y protagonismo, el valor más prometedor de los MOOC no deriva de lo que son, sino de lo que pueden llegar a ser, es decir, de las derivadas positivas que están empezando a aflorar y que tienen mucho que ver con el carácter flexible y abierto del aprendizaje que preconizan (Yuan y Powell, 2013). Estas posibilidades dimanan de algunos de sus rasgos, como son su modularidad, escalabilidad y capacidad de recombinación. Todo ello permite transitar hacia experiencias de aprendizaje personalizadas, en donde las personas pueden seleccionar sendas de aprendizaje ajustadas a sus preferencias y competencias. Esta es la lógica subyacente al concepto de comunidades de aprendizaje y participación propuesta en este artículo postulado por CSEV, y que se ha hecho tangible a partir de la creación de una nueva plataforma “paraguas” que contiene las ya existentes (como UnX) y otras nuevas que se están incorporando
