STRATEGIES FOR SUPERIOR PERFORMANCE IN RECESSIONS: PRO OR COUNTER-CYCLICAL?

Recessions are recurring events in which most firms suffer severe impacts while others are less affected or may even prosper. Strategic management has made little progress in understanding such performance differences. In a scenario of decreased demand, intensified competition, and higher uncertainty, most firms try to survive by pro-cyclically cutting costs and investments. But firms could take advantage of undervalued resources in the market to counter-cyclically invest in new business opportunities to overtake competitors. We survey Brazilian firms in various industries about the 2008-2009 recession and analyze data using PLS-SEM. We find that while most firms pro-cyclically reduce costs and investments in recessions, a counter-cyclical strategy of investing in opportunities created by changes in the market enables superior performance. Most successful are firms with a propensity to recognize opportunities, an entrepreneurial orientation to invest, and the flexibility to efficiently implement investments.

SUPPLY CHAIN RESILIENCE ANALYSIS: A BRAZILIAN AUTOMOTIVE CASE

Supply chain (SC) resilience and flexibility are important research topics receiving growing attention. However, the academic literature needs empirical studies on SC resilience capable of investigating the inter-organizational components of flexibility along different tiers. Therefore, this paper analyzes the main lack of flexibilities in three Brazilian automotive SCs that limit their resilience and therefore their capacity to better support and meet the demand changes in the marketplace. A multi-tier case study approach is adopted. Research findings identify lack of flexibilities in different tiers that inhibit the SC resilience as well as manufacturing and SC flexibilities that build SC resilience. The findings also highlight that the same SC may have the flexibility to be resilient for one of its products but not for another product, what sheds new lights on the academic literature. Finally, flexible SCs should be designed to increase SC resilience to cope with mishaps as significant demand changes.

SOCIAL BUSINESS DILEMMAS IN BRAZIL: REDE ASTACASE

ABSTRACTSocial businesses seek financial, social and even environmental results. Academic knowledge on how such organizations operate, however, has emerged more recently. This article sought to investigate qualitatively the main tensions and dilemmas occurring throughout the history of Rede Asta, a pioneer social business in direct catalog sales of artisanal products in Brazil. Results indicate the Rede Asta managers have experienced tensions and dilemmas in three of the four categories identified by Smith, Gonin, and Besharov (2013): social and financial performance, organizational aspects and learning. One of the dilemmas involves organizational aspects and learning, since Asta achieves feasibility with two organizations: a nonprofit association and a for-profit corporation. On perceptions of belonging, stakeholders declared they felt they were a part of the organization’s social and environmental goals; some even as activists.

EVALUATING THE EFFICIENCY PROGRESS WITH TECHNOLOGY IN A SPANISH HOTEL CHAIN

ABSTRACTThis paper analyzes the changes in the total factor productivity index of a Spanish hotel chain in the period from 2007 to 2010 with the purpose of identifying efficiency patterns for the chain in a period of financial crisis. The data envelopment analysis (DEA) Malmquist productivity index was used to estimate productivity change in 38 hotels of the AC chain. Results reveal AC hotels' efficiency trends and, therefore, their competitiveness in the recession period; they also show the changes experienced in these hotels' total productivity and its components: technological and efficiency changes. Positive efficiency changes were due to positive technical efficiency rather than technological efficiency. The recession period certainly influenced the performance of AC Hotels, which focused on organizational changes rather than investing in technology.

CORPORATE SOCIAL RESPONSIBILITY AND FINANCIAL PERFORMANCE: THE SPANISH CASE

ABSTRACT The enormous interest aroused by corporate social responsibility both in the academic and the business worlds forms the background for this study. Its objective is to analyze the relationship between corporate social responsibility and financial performance in view of the debate in the literature on the subject. The study focuses on a sample of Spanish companies taken from the IBEX 35 stock market index, using panel data methodology, which offers advantages in comparison to methodologies used in other studies. We analyzed the period from 2003 to 2010. Our findings suggest that there is no obvious relationship between corporate social responsibility and financial results, at least in the case of Spain.

Relationship between antropometric, corporal composition and performance in young swimmers, boys and girls

The young athlete is physiologically unique from the adult and must be considered differently. The growth and development of their bones, muscles, nerves, and organs largely dictate their physiological and performance capacities (Bar–Or, 1983; Costill & Wilmore, 1994; Stager et al., 2008). Swimming performance, and the required times to reach a competition (TAC), shoud look for those diferences and should be compatibles with them.

A blockmodel study of managerial hierarchies, verbal networks, and organizational culture in four hospitals

This study demonstrates and applies a social network methodology for studying the dynamics of hierarchies in organizations. Social network (blockmodel) analysis of verbal networks in four hospitals contrasted hierarchical and structurally equivalent partitions of the sociomatrices of frequent ties and perceptions of organizational culture. It was found that the verbal networks in these organizations follow a center periphery pattern rather than a hierarchical logic and that perceptions of culture vary more by verbal network than by formal hierarchy. The perceptions of culture of central groups in one organization are much like those of peripheral groups in another. In all four hospitals, structurally equivalent social networks are more important in predicting subcultures than are hierarchical groupings and hierarchy has a limited impact on the development of verbal networks. These findings suggest the value of an amoeba rather than a pyramid metaphor in interpreting the cultures and relational structures of organizations.

Metamorfoses em espelho de água : identidade, perfil, contextos e mudança nas (auto)representações dos professores

RESUMO: Nos últimos trinta anos, em Portugal, ocorreram processos de democratização política e de modernização da sociedade e das instituições, tendo como impulso as vontades nacionais e as mudanças ocorridas no Mundo em globalização, lideradas, no campo da educação, por agentes como a OCDE ou o Banco Mundial, e pela integração de Portugal na União Europeia. À implementação da(s) reforma(s), correspondeu uma mudança de paradigma educativo e organizacional, a criação de uma escola para todos, a emergência de novos alunos e de novos mandatos à Escola, a contingência de novas respostas educativas. Tais reformas constituiram instrumentos de mudança das organizações escolares e do sistema educativo, mas também do que significa ser professor, reformulando o desempenho e a “performatividade” docente (Ball, 2002), induzindo uma nova “identidade social” (Bernstein, 1996 e Dubar, 2006), produzindo novos modos de “fabricação da alma dos professores” (Foucault, 1996). Neste sentido, a autora procurou analisar, numa perspectiva crítica, as representações de professores do Ensino Básico, sobre os mecanismos de (re)configuração das suas identidades/perfis profissionais, recorrendo a uma investigação qualitativa descritiva, que privilegia a análise de conteúdo dos seus discursos sobre o tema, recolhidos segundo a técnica focus group. O estudo indiciou que os alunos são factor de realização, de risco e de mudança do perfil docente, actuando como uma quinta dimensão da (re)construção identitária dos Professores, a par da formação, do associativismo, do Estado e do Mercado, constituindo factor importante a ter em conta nos estudos sobre identidade docente. ABSTRACT: In the past thirty years, in Portugal, radical changes on politics and policies have been occurring, to achive the society and its institutions democratization and modernization, led by national wills and the changes occured in the World, stimulated, in the Education area, by global agencies like OECD, or the World Bank, and the integration of Portugal in the European Union. These reforms are connected to a new educational and organizational paradigm, the creation of a school for all, the emergence of new pupils, new demands to School and teachers, the imperative of new pedagogical solutions for educational problems, and are not only changing instruments in schools and in the educational system, but are also a powerful way to change “what to be a teacher” means, to re-formulate the teaching performance and “performativity” (Ball, 2002), to recompose his/her “social identity” (Bernstein, 1996; Dubar, 2006), or, in Michel Foucault (1996) words, to produce “new ways to manufacture teachers soul”. In this sense, the author intended to analyze, on a critical perspective, the representations of portuguese teachers of basic education (K12), on the mechanisms of (re)configuration of their professional identities/profiles, appealing to a qualitative descriptive research, which privileges the analysis of content of their speeches on the subject, collected according to the focus group technique, what, in its development, was brought near a circle of culture (in the sense of Paulo Freire‟s pedagogy). At least, pupils are the most important references and motivation to teachers changes, reflecting professional satisfaction and well done, but also risk, acting like a fifth dimension of teachers identity (re)construction, together with training, associative involvement, State and Market, and they must be considered on teatching identity studies.

A System Dynamics-Based Simulation Experiment for Testing Mental Model and Performance Effects of Using the Balanced Scorecard

This study develops a theoretical model that explains the effectiveness of the balanced scorecard approach by means of a system dynamics and feedback learning perspective. Presumably, the balanced scorecard leads to a better understanding of context, allowing managers to externalize and improve their mental models. We present a set of hypotheses about the influence of the balanced scorecard approach on mental models and performance. A test based on a simulation experiment that uses a system dynamics model is performed. The experiment included three types of parameters: financial indicators; balanced scorecard indicators; and balanced scorecard indicators with the aid of a strategy map review. Two out of the three hypotheses were confirmed. It was concluded that a strategy map review positively influences mental model similarity, and mental model similarity positively influences performance.

O trabalho em equipas docentes e o desenvolvimento da Educação Física

RESUMO: O sucesso das respostas aos novos desafios, exigências e expectativas que, nos dias de hoje, recaem sobre a escola, parece depender da concepção das estratégias organizacionais que globalmente a escola define, tendo em conta as características do contexto e das populações que serve. Depende por isso do modo como os actores chave se organizam e trabalham. Os modos de entender o trabalho docente em equipa prenunciam formas de entender a acção educativa e de conduzir a aprendizagem dos alunos. Tomando como ponto de partida as nossas experiências profissionais, este trabalho constitui uma reflexão sobre as possibilidades de desenvolvimento da Educação Física, baseada na escola e sustentada na organização do trabalho dos seus professores. Elaborando uma síntese dos principais problemas do seu desenvolvimento discutem-se as possibilidades e as vantagens da organização do trabalho dos professores em equipas, num contexto organizacional marcado por avanços e retrocessos nos processos de descentralização e atribuição de autonomia às escolas. Enquadra-se a organização do trabalho docente no âmbito das culturas de escola. Revisita-se o conceito de trabalho em equipa, distinguindo-o da simples participação nas estruturas da escola, realçando a sua importância na construção e gestão de conhecimento profissional através do estabelecimento de parcerias sinérgicas, onde o desempenho de papéis de liderança tem uma enorme importância. ABSTRACT: Successful responses to the new challenges, demands and expectations that currently are ascribed to schools seem to depend on the design of organizational strategies that broadly define the school, taking into account the characteristics of its context and the population it serves. Therefore, their success depends on how the key players are organized and work. The ways of perceiving the teaching team work forecast the ways of understanding the educational activity and how to lead learning. Starting from our own professional experience, this study is a reflection on the school based development of physical education, sustained by the organization of their teachers’ work. On organizing a summary of the major problems found in the development of this subject, we discuss the feasibilities and the gains got from the organization of teachers' teamwork, in an organizational context marked by promises and setbacks in the processes of decentralization and schools autonomy. The organization of teaching is to be seen as part of the school culture. We review the concept of teamwork as distinct from mere participation in the structures of the school, and its importance in the construction and management of professional knowledge will be highlighted by the establishment of synergistic partnerships, in which the performance of leadership roles is of the greatest importance. RÉSUMÉ: Le succès des réponses aux nouveaux défis, les exigences et les attentes que dans ces jours, s’accomplissent sur l'école, semble dépendre de la conception des stratégies d'organisation qui définit de façon générale l'école, en tenant compte des caractéristiques du contexte et des populations qu'elle dessert. Tout cela dépend donc de la façon dont les acteurs principaux sont organisés et travaillent. Les façons de comprendre l'équipe pédagogique démontrent des formes de comprendre l'activité éducative et de conduire à l'apprentissage des élèves. En prenant comme point de départ nos expériences professionnelles, ce travail est une réflexion sur le potentiel de développement de l'Éducation Physique, dépendante de l'école et soutenue dans l'organisation du travail de leurs enseignants. En préparant une synthèse des principaux problèmes de leur développement, on discute les possibilités et les avantages de l'organisation du travail des enseignants dans les équipes, dans un contexte organisationnel marqué par des avancées et des reculs dans le processus de décentralisation et l'accomplissement de l'autonomie aux écoles. On encadre l'organisation du travail des enseignants dans le champ des cultures de l’école. On revoit le concept du travail en équipe, en le distinguant de la simple participation dans les structures de l'école, en soulignant son importance dans la construction et gestion des connaissances professionnelles à travers l'établissement de partenariats synergiques, où les rôles de leadership joue un rôle d'une grande importance.

Diagnostic performance of visual screening tests in the elderly

This study aimed to determine and evaluate the diagnostic accuracy of visual screening tests for detecting vision loss in elderly. This study is defined as study of diagnostic performance. The diagnostic accuracy of 5 visual tests -near convergence point, near accommodation point, stereopsis, contrast sensibility and amsler grid—was evaluated by means of the ROC method (receiver operating characteristics curves), sensitivity, specificity, positive and negative likelihood ratios (LR+/LR−). Visual acuity was used as the reference standard. A sample of 44 elderly aged 76.7 years (±9.32), who were institutionalized, was collected. The curves of contrast sensitivity and stereopsis are the most accurate (area under the curves were 0.814−p = 0.001, C.I.95%[0.653;0.975]— and 0.713−p = 0.027, C.I.95%[0,540;0,887], respectively). The scores with the best diagnostic validity for the stereopsis test were 0.605 (sensitivity 0.87, specificity 0.54; LR+ 1.89, LR−0.24) and 0.610 (sensitivity 0.81, specificity 0.54; LR+1.75, LR−0.36). The scores with higher diagnostic validity for the contrast sensibility test were 0.530 (sensitivity 0.94, specificity 0.69; LR+ 3.04, LR−0.09). The contrast sensitivity and stereopsis test's proved to be clinically useful in detecting vision loss in the elderly.

Diagnostic performance of visual screening tests in the elderly

The aging of Portuguese population is characterized by an increase of individuals aged older than 65 years. Preventable visual loss in older persons is an important public health problem. Tests used for vision screening should have a high degree of diagnostic validity confirmed by means of clinical trials. The primary aim of a screening program is the early detection of visual diseases. Between 20% and 50% of older people in the UK have undetected reduced vision and in most cases is correctable. Elderly patients do not receive a systematic eye examination unless a problem arises with their glasses or suspicion vision loss. This study aimed to determine and evaluate the diagnostic accuracy of visual screening tests for detecting vision loss in elderly. Furthermore, it pretends to define the ability to find the subjects affected with vision loss as positive and the subjects not affected with the same disease as negative. The ideal vision screening method should have high sensitivity and specificity for early detection of risk factors. It should be also low cost and easy to implement in all geographic and socioeconomic regions. Sensitivity is the ability of an examination to identify the presence of a given disease and specificity is the ability of the examination to identify the absence of a given disease. It was not an aim of this study to detect abnormalities that affect visual acuity. The aim of this study was to find out what´s the best test for the identification of any vision loss.

Analysis of constructed wetland performance for irrigation reuse

Most of the wastewater treatment systems in small rural communities of the Cova da Beira region (Portugal) consist of constructed wetlands (CW) with horizontal subsurface flow (HSSF). It is believed that those systems allow the compliance of discharge standards as well as the production of final effluents with suitability for reuse. Results obtained in a nine-month campaign in an HSSF bed pointed out that COD and TSS removal were lower than expected. A discrete sampling also showed that removal of TC, FC and HE was not enough to fulfill international irrigation goals. However, the bed had a very good response to variation of incoming nitrogen loads presenting high removal of nitrogen forms. A good correlation between mass load and mass removal rate was observed for BOD5, COD, TN, NH4-N, TP and TSS, which shows a satisfactory response of the bed to the variable incoming loads. The entrance of excessive loads of organic matter and solids contributed for the decrease of the effective volume for pollutant uptake and therefore, may have negatively influenced the treatment capability. Primary treatment should be improved in order to decrease the variation of incoming organic and solid loads and to improve the removal of COD, solids and pathogenic. The final effluent presented good physical-chemical quality to be reused for irrigation, which is the most likely application in the area.

Power converter topologies for wind energy conversion systems: Integrated modeling, control strategy and performance simulation

This paper presents new integrated model for variable-speed wind energy conversion systems, considering a more accurate dynamic of the wind turbine, rotor, generator, power converter and filter. Pulse width modulation by space vector modulation associated with sliding mode is used for controlling the power converters. Also, power factor control is introduced at the output of the power converters. Comprehensive performance simulation studies are carried out with matrix, two-level and multilevel power converter topologies in order to adequately assert the system performance. Conclusions are duly drawn.
