Tourism is a phenomenon that moves millions of people around the world, taking as a major driver of the global economy. Such relevance is reflected in the proliferation of studies in the overall area known as tourism, under various perspectives and backgrounds. In the light of such multitude of insights our study aims at gaining a deeper understanding of customer profiling and behavior in cross-border tourism destinations. Previous studies conducted in such contexts suggest that cross-border regions (CBRs) are an attractive and desirable idea, yet requiring further theoretical and empirical research. The new configuration of many CBRs calls for a debate on issues concerning its development, raising up important dimensions, such as, organization and planning of common tourism destinations. There is still a gap in the understanding of destination management in CBRs and the customer profile and motivations. Overall this research aims at attaining a deeper understanding of the profile and behavior of consumers in tourism settings, addressing the predisposition for the destination. The study addresses the following research question: “What factors influence customer behavior and attitudes in a CBRs tourism destination?” To address our question we will take an interdisciplinary perspective bringing together inputs from marketing, tourism and local economics. When addressing consumer behavior in tourism previous studies considered the following constructs: involvement, place attachment, satisfaction and destination loyalty. In order to establish the causal relationships in our theoretical model, we intend to develop a predominant quantitative design, yet we plan to conduct exploratory interviews. In the analysis and discussion of results, we intend to use Structural Equation Modeling. It will further allow understanding how the constructs in the research model relate to each other in the specified context. Results are also expected to have managerial implications. Consequently our results may assist decision makers in developing their local policies.

The way an employee behaves in his work can be influenced by the organisational and professional commitment. Nurses are professionals who are guided by organisational and professional goals and values. Among nurses, professional commitment may be an important antecedent of organisational citizenship behaviours. The study shows how organisational and professional commitment is related with nurses’ organisational citizenship behaviours. Data from a sample of 420 nurses working in two hospitals --- the Hospital of St. Marcos, Braga and the Hospital Centre of Alto Ave, Guimarães and Fafe units were collected. The main findings are as follows: (a) organisational commitment and professional commitment contribute to the explanation of nurses’ organisational citizenship behaviours, (b) affective organisational commitment, continuance organisational commitment --- personal sacrifice, affective professional commitment and continuance professional commitment explain 28.6% of variance of organisational citizenship behaviours. © 2013 Instituto Politécnico do Cávado e do Ave (IPCA).

ABSTRACT The objective of this study was to analyze the phenotypic correlation and path analysis of traits related to plant architecture, earliness and grain yield in F2, BC1 and BC2 generations, from crosses between cowpea cultivars BRS Carijó and BR14 Mulato. Most phenotypic correlations of the examined traits were concordant in statistical significance, with approximate values ​​among the examined generations. For the trait seed weight, significant and positive phenotypic correlations were observed in the three generations only for the trait number of secondary branches. The values ​​of the direct effects were in agreement with the values ​​of the phenotypic correlations, which indicate true association by the phenotypic correlation among the traits of grain yield examined. Path analysis indicated that the selection of productive plants will result in early plants and an increased number of secondary branches. In F2, plants with shorter length of the main branch and shorter length of secondary branches can be obtained. The causal model explained 15 to 30% of the total variation in grain weight in relation to the traits examined. The analyses indicated the possibility of selecting plants with a higher and early grain yield, shorter length of primary branches and lower number of nodes, which are important variables for mechanical or semi-mechanical harvesting.

Este estudo tem como principal objetivo analisar a relação causal entre um conjunto de variáveis de política monetária e o mercado acionário brasileiro, representado pelo Ibovespa, e para tal utilizará o procedimento de Bernanke (1986). Buscou-se analisar o efeito dos choques inesperados nas variáveis de política monetária, além de analisar o poder explanatório de cada uma das variáveis do modelo sobre o Ibovespa. Os resultados obtidos deixam claro que as taxas de juros de curto e longo prazo e a taxa de câmbio impactam contemporaneamente o Ibovespa. Contudo, a maior sensibilidade do índice está na taxa de câmbio, mostrando a importância exercida pelo câmbio no mercado acionário brasileiro. Uma depreciação inesperada no câmbio da ordem de 10% impacta negativamente o Ibovespa em 11,6%. Como na função impulso resposta, o câmbio é a variável que tem o maior poder explanatório.

With the purpose of at lowering costs and reendering the demanded information available to users with no access to the internet, service companies have adopted automated interaction technologies in their call centers, which may or may not meet the expectations of users. Based on different areas of knowledge (man-machine interaction, consumer behavior and use of IT) 13 propositions are raised and a research is carried out in three parts: focus group, field study with users and interviews with experts. Eleven automated service characteristics which support the explanation for user satisfaction are listed, a preferences model is proposed and evidence in favor or against each of the 13 propositions is brought in. With balance scorecard concepts, a managerial assessment model is proposed for the use of automated call center technology. In future works, the propositions may become verifiable hypotheses through conclusive empirical research.

A atmosfera de uma loja é capaz de provocar emoções e comportamentos que estimulam a compra. Entre as suas dimensões, está o aroma ambiental, adicionado artificialmente ao ambiente. Este artigo investiga a relação entre a presença de aroma ambiental no varejo e as avaliações de loja, ambiente de loja e produtos, além das intenções comportamentais relativas ao retorno e ao tempo gasto na loja. A pesquisa teve uma etapa exploratória, exame de publicações em fisiologia, psicologia e comportamento do consumidor, para construção do referencial teórico e formulação das hipóteses, e outra causal, quase experimento, para identificar as relações de causa e efeito na presença de aroma. O estudo foi conduzido em uma butique de frutos do mar, e os instrumentos de coleta de dados, escalas de diferencial semântico, basearam-se em pesquisas similares. As análises incluíram técnicas de estatística descritiva e teste de hipóteses. Os resultados revelaram que a presença de aroma ambiental não aumentou as avaliações nem a intenção de retorno, mas reteve o consumidor por mais tempo na loja.

This paper shows the results of the empirical study conducted in 186 tourist accommodation businesses in Spain certified under the "Q for Tourist Quality", own System Quality Management. It was raised with the purpose of analyzing the structure of the relationship between critical quality factors and results-social impact, how they operate and the level of their influence on obtaining these results within the company. Starting from a deep theoretical revision we propose a theoretical model together with the hypotheses to be tested, and we proceed to validation using the technique of Structural Equation Models. The results obtained show that companies wishing to improve their social impact should take into account that leadership is the most important factor to achieve it. Leadership indirectly affects the social impact through its influence on alliances and resources, quality policy/planning, personnel management and learning.

This paper reviews the understanding I have gained from several years of research, and from several more years of ongoing discussions with industry leaders regarding the nature of competitiveness among tourism destinations. This understanding has been captured, in summary form, in the model of Destination Competitiveness/Sustainability (Ritchie and Crouch, 2003). This model contains seven (7) components which we have found to play a major role, from a policy perspective, in determining the competitiveness/sustainability of a tourism destination. In addition to the valuable understanding which these seven components provide from a policy perspective, the specific elements of each the major components provide a more useful/practical guidance to those who are responsible for the ongoing management of a DMO (Destination Management Organization). With this overview in mind, this paper will provide a detailed review and explanation of the model that I have developed with colleague, Dr. Geoffrey I. Crouch of Latrobe University in Melbourne, Australia. Based on previous presentations throughout the world, it has proven very helpful to both academics and practitioners who seek to understand the complex nature of tourism destination competitiveness/sustainability.

This study aims to be a contribution to a theoretical model that explains the effectiveness of the learning and decision-making processes by means of a feedback and mental models perspective. With appropriate mental models, managers should be able to improve their capacity to deal with dynamically complex contexts, in order to achieve long-term success. We present a set of hypotheses about the influence of feedback information and systems thinking facilitation on mental models and management performance. We explore, under controlled conditions, the role of mental models in terms of structure and behaviour. A test based on a simulation experiment with a system dynamics model was performed. Three out of the four hypotheses were confirmed. Causal diagramming positively influences mental model structure similarity, mental model structure similarity positively influences mental model behaviour similarity, and mental model behaviour similarity positively influences the quality of the decision.

O Balanced Scorecard (BSC) tem vindo a revelar-se um conceito popular como ferramenta de suporte à descrição e implementação da estratégia organizacional. Esta abordagem propõe que os gestores se foquem no desenvolvimento e utilização dum número reduzido de indicadores críticos de desempenho, financeiros e não financeiros, que combinam diferentes disciplinas e perspectivas da organização e que estão articulados numa cadeia causal que explica de forma consistente o desempenho futuro de acordo com a estratégia formulada. Contudo, diversas dúvidas e críticas tem emergido relativamente à qualidade do processo de desenvolvimento do BSC e que colocam em causa a consistência e a validade da estrutura de indicadores que constitui o instrumento fundamental para o controlo da implementação da estratégia. Com o propósito de ultrapassar estes problemas, uma abordagem baseada na modelação e simulação dinâmica (dinâmica de sistemas) é proposta como suporte ao processo de desenvolvimento do BSC. Esta abordagem permite acelerar e melhorar a aprendizagem dos gestores acerca do processo de criação futura de valor que está associado à estratégia formulada e respectiva implementação, contribuindo assim para a validade e consistência da estrutura de indicadores do BSC.

RESUMO: O desafio era mostrar aquilo que poucos vêem e ninguém mede, mas que pode ajudar a resolver muitos problemas no sector da restauração. Assim, o objectivo é identificar, analisar e mensurar os custos de desempenho ocultos no dia-a-dia de um restaurante. A síntese bibliográfica reflecte a pesquisa efectuada, visando um método que nos ajudasse a medir concretamente os disfuncionamentos que ocorrem nos desempenhos diários dos empregados de mesa de um restaurante. Descobrimos a abordagem socioeconómica de Henri Savall e o seu método de avaliação dos custos de desempenho ocultos. Explicitamos de seguida este método de Savall e apresentamos uma síntese da história do restaurante, com o intuito de mostrar que, desde o seu nascimento, o restaurante é muito mais do que um local onde vamos comer. Feito este caminho, apresentamos o restaurante de luxo que escolhemos e onde aplicámos o método de avaliação dos custos de desempenho ocultos com algumas alterações, pois originalmente este método foi desenvolvido e aplicado ao sector da Indústria. Terminamos com a explicação da forma como aplicámos o método e os respectivos resultados encontrados. Concluímos que a aplicação do método escolhido revela informações preciosas para a gestão e para a tomada de decisão e enfatiza a importância do trabalho efectuado pelos empregados de mesa no seu dia-a-dia. ABSTRACT: Our challenge was to show what few people see and nobody measures, but that can help to solve lots of problems in the restaurants line of business. Our objective is to identify, analyze and measure the performance hidden costs in the daily activity of a restaurant. The bibliography used reflects the researches made, searching for a method which would help us to measure in detail the dysfunctions which occur in the daily performance of the waiters in a restaurant. We discovered the socioeconomic approach of Henri Savall and its evaluation method of the performance hidden costs. Next, we explain Savall’s method and present a synthesis of the restaurant history with the aim to show that, since its birth, the restaurant is much more than the place where people go to eat. This path made, we present the luxury restaurant which was chosen and where we have applied the evaluation method of the performance hidden costs, with some minor changes, because originally this method was developed and applied in the Industry sector. We finalize this work with the explanation of the way how we applied the method and with the presentation of the results. We have concluded that the application of the chosen method of study reveals vital information for the management department and for the decision processes, and that it emphasizes the importance of the waiters in their daily work inside a restaurant.
