Abstract
Purpose
The purpose of this paper is to construct a numerical model for the numerical analysis of the hydraulic transient profile in Trabalhador channel for filling and emptying maneuvers and to determine the water level in time. Model results support operational managers in the decision-making process.
Design/methodology/approach
Physical data were provided for the construction and calibration of the numerical model. The equations of Saint-Venant were approximated by a finite difference scheme and the numerical model was written in Fortran. The results of filling and emptying of the channel simulations were compared with the measured water levels.
Findings
Measured water levels and those simulated by the numerical model have shown good correlation. The time recorded for the filling and emptying of the canal was also close between the measured and simulated data. The simulation design flow pointed to inundation in the channel banks. Simulation water levels were slightly higher than those measured.
Research limitations/implications
In this model, the combination of canals and pressure conduits was not considered.
Practical implications
The findings confirm the measured time for filling and emptying of the canal, as well as inundation of canal banks for the maximum design flow. These results help in the management process.
Originality/value
This paper presents a numerical model for hydraulic transient analysis in channels with good agreement with the field data.

Abstract
Purpose
The West African Republic of Guinea-Bissau has been unstable since gaining its independence in 1974. The 2014 presidential and parliamentary elections are being closely analyzed to study how the United Nations and the Guinean people have reacted to the outcomes of these elections. The paper aims to discuss these issues.
Design/methodology/approach
Sociological methodologies and a comparative approach have been used in this paper to understand why the elections in 2014 were so important in this country.
Findings
The author finds that stability is possible in Guinea-Bissau after years of political uncertainties.
Originality/value
Particular focus has been paid to studying the responses of specific aspects of society, including the youth population, the political elite, the main political party, the African Party for the Independence of Guinea and Cape Verde, the opposition parties and the army and whether these different groups will be able to cooperate after electing a sustainable and relatively wide-ranging government.

Abstract
The organization of events in public spaces in the cities of Oporto, Vila Nova de Gaia (both in Portugal), and Barcelona (Spain) led us to propose a classification of thematic cities. The conclusions are the result of social representations of organizers and sponsors in the three cities and, thus, it is a qualitative study carried out in research Ph.D. in Sociology at the Faculty of Letters of the University of Oporto. We propose the presentation of some events organized in three public spaces – Aliados Avenue in Oporto, Cais de Gaia’s waterfront in Vila Nova de Gaia, and Ramblas in Barcelona – to make its framing in terms of objectives, motivations, and public. We also appealed to the social representations of interviewees to evaluate the quality and structure of public spaces in the two cities in the metropolitan area of Oporto in comparison with the Catalan city. Finally, we propose the typification of the three cities according to the features presented throughout the chapter.

Abstract
Purpose
The purpose of this paper is to discuss the role of contemporary architecture in heritage protection, reinterpretation and reuse, an issue that has become increasingly relevant due to the recognition of architectural heritage as a key factor for cultural and economic development.
Design/methodology/approach
In Portugal, as elsewhere in Europe, cultural heritage management has often been associated with the creation of new museum spaces, namely, within national monuments and archaeological sites. Drawing on restoration theories and international charters, this paper analyses and compares two parallel interventions recently built inside São Jorge Castle, in Lisbon: the Museum Centre (Victor Mestre and Sofia Aleixo, 2007-2008) and the Archaeological Site (João Luís Carrilho da Graça, 2008-2010). This approach offers insight on the complexity of addressing and reconfiguring the profusion of past transformations within a single monument.
Findings
These two complementary museum spaces are representative of different attitudes towards heritage appropriation, substantiating the thesis that musealizing always entails the creation of narratives, which translate history and heritage into architectural and curatorial discourses. Besides meeting the functional requirements of specific museum programmes, such interventions frequently deal with the challenge of opening up new perspectives on the past.
Originality/value
Considering the central role of communication in contemporary museums, this paper discusses how heritage musealization can contribute to the translation of historical evidence into updated iconographies, narratives and dialogues. Furthermore, the unique characteristics of this twofold case study can provide an insightful contribution for a broader debate on the reinterpretation of iconic monuments and sites.

Abstract
Purpose
This study aims to analyze the entrepreneurial intention (EI) of Colombian researchers using machine learning (ML) techniques, considering their academic activity, contexts and social norms (SN).
Design/methodology/approach
Unsupervised classification techniques were applied, including principal component analysis, hierarchical clustering with the Ward method and a logistic model to evaluate the classification. This was done to group researchers according to their characteristics and EI.
Findings
The methodology used allowed the identification of three groups of academics with distinct characteristics, of which two showed a high presence of EI. The results indicate that EI is influenced by the connection with the private sector (consulting, intellectual property and applied research) and by the lack of institutional support from universities. Regarding SN, only the preference for entrepreneurial activity over being an employee and the social appreciation of entrepreneurial dedication were identified as predictors of EI.
Originality/value
The use of ML techniques to study the EI of researchers is uncommon. This study highlights the ability of the methodology used to identify differences between two groups of academics with similar characteristics but different levels of EI. One group was identified that, despite rejecting values associated with entrepreneurs, has a high predisposition to develop a career as an entrepreneur. This provides valuable information for designing policies that promote EI among Colombian researchers.

Abstract
Purpose
The primary aim of the current study is to validate the theoretical model presented by Demir (2021a, b, c) via empirical evidence. In this respect, the study intends to offer a holistic pathway for obtaining both external and internal advantages from the implementation of ISO 9001, with a particular emphasis on developing countries.
Design/methodology/approach
The research utilized an empirical methodology to investigate the research objective. Data were collected from various sources, including employees and managers of the various companies. In this context, a model was developed, and 170 data points were collected from businesses in the Kurdistan region of Iraq in order to test the hypotheses in this model.
Findings
After the collected data passed the reliability and validity test, the hypotheses designed were tested by applying the partial least squares method. When the results were examined, it was observed that organizational culture and organizational learning variables were the two key antecedents that these factors would emerge after applying ISO 9001 practices with discipline for a certain period of time and that organizational benefits could be obtained only as a result of them. Detailed results and suggestions were given to managers and theorists as a result of the analysis.
Originality/value
This study contributes to the literature as an empirical application of the theoretical work written by Demir in 2021. Demir's work, which produced a theoretical concept based on many empirical and theoretical studies done before, still needs much more empirical work in developing countries.
