Abstract
Purpose
The purpose of this paper is to analyse the causal relationships among the dimensions that explain consumer-based brand equity, and to determine the importance of each dimension in the assessment of overall brand equity.
Design/methodology/approach
A research instrument proposed by Yoo and Donthu was applied to undergraduate students of the University of Coimbra. Two leading brands in the Portuguese beer market were used in the study. Respondents were randomly assigned to one brand and were asked to rate all items on seven Likert-type scales. Based on Aaker’s conceptual framework, a structural equation model (SEM) was designed to analyse the proposed relationships.
Findings
A causal order between brand equity dimensions was established. The results suggest that the positive effects of perceived quality and brand awareness on overall brand equity are mediated by brand loyalty.
Research limitations/implications
Although the exclusion of brand associations’ dimensions in the SEM improves the validity of the constructs, it should be regarded as a limitation, given its importance in brand equity building.
Practical implications
Marketing managers should focus on brand loyalty in order to increase overall brand equity, and should give special attention to perceived quality, since it is the factor with the strongest impact on brand loyalty.
Originality/value
The identification of the causal relations among brand equity dimensions and the analysis of their influence in overall brand equity, not yet clearly validated in the literature.

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
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract
Globalisation is generally defined as the “denationalisation of clusters of political, economic, and social activities” that destabilize the ability of the sovereign State to control activities on its territory, due to the rising need to find solutions for universal problems, like the pollution of the environment, on an international level. Globalisation is a complex, forceful legal and social process that take place within an integrated whole with out regard to geographical boundaries. Globalisation thus differs from international activities, which arise between and among States, and it differs from multinational activities that occur in more than one nation‐State. This does not mean that countries are not involved in the sociolegal dynamics that those transboundary process trigger. In a sense, the movements triggered by global processes promote greater economic interdependence among countries. Globalisation can be traced back to the depression preceding World War II and globalisation at that time included spreading of the capitalist economic system as a means of getting access to extended markets. The first step was to create sufficient export surplus to maintain full employment in the capitalist world and secondly establishing a globalized economy where the planet would be united in peace and wealth. The idea of interdependence among quite separate and distinct countries is a very important part of talks on globalisation and a significant side of today’s global political economy.

Abstract
Purpose
Discussion regarding systems that promote innovation, aptly named innovation ecosystems, has been intensifying both in academia and business. The purpose of this paper is to introduce the activity theory as a theoretical framework for conceptualising and studying innovation ecosystems. Using the activity theory, it investigates elements that affect the success and viability of innovation ecosystems formed between startups and incumbent firms, collaborating with an established firm within the context of an open innovation programme.
Design/methodology/approach
This study uses an exploratory case research approach and proposes the activity theory as a theoretical background to be used in innovation ecosystem research. Based on this approach, this study draws from interviews and research observations in an innovation ecosystem formed between an established firm and various startups that aim to co-develop innovative offerings.
Findings
By applying the activity theory tools, this study identifies several contradictions between interacting actors of this innovation ecosystem that can adversely affect the innovation process. Furthermore, it proposes the use of the activity theory as a fitting theoretical lens to study innovation ecosystems.
Originality/value
The novelty of this study is related to the focus on the incumbent–startup context for extending the innovation ecosystem literature. Using the activity theory as a viable methodological tool allows us to conceptualise firms as social constructs and hence pinpoint inner characteristics that can affect and shape their interactions and the broader ecosystem. This process is further enhanced by the use of primary data that give unique insights into the inner workings of innovation ecosystems by identifying underlying contradictions.

Abstract
Purpose
This study aims to explain the state-of-the-art machine learning models that are used in the intrusion detection problem for human-being understandable and study the relationship between the explainability and the performance of the models.
Design/methodology/approach
The authors study a recent intrusion data set collected from real-world scenarios and use state-of-the-art machine learning algorithms to detect the intrusion. The authors apply several novel techniques to explain the models, then evaluate manually the explanation. The authors then compare the performance of model post- and prior-explainability-based feature selection.
Findings
The authors confirm our hypothesis above and claim that by forcing the explainability, the model becomes more robust, requires less computational power but achieves a better predictive performance.
Originality/value
The authors draw our conclusions based on their own research and experimental works.
