Abstract
Purpose
The purpose of this study is to rethink the issue of publicity from a cross-cultural and evolutionary perspective.
Design/methodology/approach
Assuming that there is a dominant paradigm in the studies of the public sphere centered on Habermas’ ideas, media theory (and especially Luhmann who is considered as a media theorist) is selected as a new context that provides different concepts, ideas, language games and metaphors that allow the re-foundation of the study of publicity.
Findings
Publicity as a social structure emerges – and acquires different forms during history – out of the complex dynamics resulting from the interaction between success media, such as power, and different kinds of dissemination media.
Originality/value
A research into the forms of publicity not only promotes awareness of the ubiquity of the phenomenon across cultural evolution, but also offers tools to make new discoveries and systematize what is already known about the subject and its ramifications.

Abstract
Purpose
The aim of this paper is related to an analysis of hydrodynamic lubrication of circular thrust bearings.
Design/methodology/approach
The modified Reynolds equation was treated to obtain a hybrid numerical-analytical solution through the generalized integral transform technique (GITT) for the problem.
Findings
Numerical results for the engineering parameters such as pressure field, load capacity and power consumption were thus produced as functions of the radial and circumferential directions. These parameters depend on the geometry of sector-shaped used: Rayleigh pad with 4, 8 and 16 steps. Comparing among them, on the numerical point of view, the Rayleigh pad geometry with N = 16 steps has a better satisfactory performance because it has a lower power consumption.
Originality/value
The present GITT results and those obtained by the finite volume method (FVM) from previous works in the literature were confronted to verify whether the results are consistent and to demonstrate the capacity of the GITT approach in handling thrust bearing problems.

Abstract
Purpose
The purpose of this paper is to develop a novel method to analyse dynamic interactions of stakeholders to explain how a set of agents can act by considering the power/influence positions.
Design/methodology/approach
A novel mathematical application uses the importance of characteristics algorithm in combination with composition max-min to compare, group and order information according to the importance of its characteristics. The mathematical application is focused on a strategic analysis, evaluating stakeholder dynamics through power relationships.
Findings
The results show a comparison of the relationships among each of the stakeholders to obtain the relative intensity and importance of relationships between them, given by the fuzzy matrix FRInM and the fuzzy matrix FRIM, respectively. This application provides a useful tool for a dynamic analysis of stakeholders in a complex environment, where the best approach to performing a strategic analysis process is sought.
Research limitations/implications
The main implication of the proposed approach is taking into account the importance of information to establish the boundaries and relationships of each characteristic according to its intensity. However, limitations are due to the nature of this research, based on theoretical assumptions regarding stakeholders and the use of a hypothetical example to show the operation of algorithms.
Originality/value
The primary advantage of this proposition is that it takes into account the importance of information to establish the relationships among the characteristics according to their intensity. In addition, it performs multiple comparisons among each characteristic of the information. The interests and opinions of decision makers can be parameterised. A mathematical application shows how each interest group could be classified and related according to subjective information.

Abstract
Purpose
This research aims at the theory of planned behavior (TPB) and the global entrepreneurship monitor (GEM) framework – How can cognitive traits for entrepreneurship be used by incubators and accelerators?
Design/methodology/approach
In this research the authors analyze the factors that catalyze the founding of new technology-based firms. From a practitioner stand-point, the GEM posits that these factors can be classified as contextual, social and individual factors. The present study focuses on the latter, looking into how demographic characteristics, possession of human capital and cognitive traits interrelate. The authors rely on a sample of 141 technological new ventures being incubated in Madrid, Spain, which is analyzed with the multilayer perceptron technique.
Findings
The results show that cognitive traits, as defined in the TPB, act as the “last mile” in the entrepreneurial decision process, while demographic and human capital factors appear to antecede them. These results are relevant for incubators and accelerators, which now gain a better, more complete understanding of success factors of their incubatees.
Originality/value
This research deals both with practitioners' view of entrepreneurship and with scientific literature, intertwining both with the purpose of providing valuable information for incubators and accelerators.

Abstract
Purpose
The purpose of this paper is to measure the relationships between advanced manufacturing technologies (AMTs) categories (stand-alone, intermediated and integrated systems) implementation and design, process and commercial benefits obtained.
Design/methodology/approach
A survey is designed with benefits gained from AMT implementation as well as its categories, which is applied to the maquiladora industry. A structural equation model with data from 383 responses is used to measure the relationship between AMT categories and benefits gained using nine hypotheses that are tested statistically significant using partial least squares. Also, using conditional probabilities, a sensitivity analysis reports how low and high levels from AMT implementation influence on the obtained benefits.
Findings
Integrated systems are the most important AMT for maquiladoras and have the strongest impact on design, processes and commercial benefits.
Research limitations/implications
Data obtained support the model, but results may be different in another industrial sector and countries with different labor culture and technological level.
Practical implications
Managers in maquiladora industry must focus their attention on integrated manufacturing systems, because high implementation levels guarantee the biggest probability to gain benefits in design, production process and commercial.
Originality/value
The relationship between AMT and their benefits has not been measured in depth, and this paper contributes to understand that problem. In addition, this paper is the first to report a sensitivity analysis that enables managers to acknowledge the probability of obtaining certain benefits.

Abstract
Purpose
Although most of the literature supports the existence of a substitutive relationship between exploration and exploitation, some authors suggest that this relationship is complementary (ambidexterity), and others argue that there is no relationship. This paper aims to introduce organizational innovation into the analysis and discusses which of these three relationships prevails.
Design/methodology/approach
Analyses were performed using data from Spanish Technological Innovation Panel for the period 2008-2013. It should be emphasized that the use of panel data is essential in the analysis of the interaction of exploration and exploitation, as exploration only makes sense in the long run. Econometric strategy uses a two-stage selection model, estimated using the Wooldridge’s (1995) consistent estimator for panel data with sample selection. To perform the test, the hypothesis uses the approach of complementarity.
Findings
The results show that the relationships exploration-organizational innovation and exploitation-organizational innovation are complementary, provided that the analysis is performed on companies that simultaneously carry out exploration and exploitation activities, respectively. This indicates that the achievement of ambidexterity is strongly conditioned by the simultaneous realization of organizational innovations.
Practical implications
Managers and policymakers should be aware that the simultaneous implementation of exploration and exploitation yields better results when the corresponding organizational innovations are also implemented.
Originality/value
This paper extends the empirical investigation of the relationship between exploration and exploitation, seen in conjunction with organizational innovation, and using the complementarity approach as a research tool.

Abstract
This chapter intends to make an extended periodization of economic discussions that have taken place in Latin America throughout its history. The task is ambitious; we begin, however, with the periodization elaborated by Oreste Popescu, which we then expand and modify. As educators, we still have to work on the training of Latin American economists, due to the lack of knowledge they have not only about the region as a whole, but also of the economic debates that took place within it. This work is a first approximation and provocation aimed to jumpstart a discussion on these issues.

Abstract
Both Bolivia and Uruguay broke ranks with the global drug prohibition regime by introducing novel drug policies. State control of the production and supply of coca and cannabis represents a clear departure from both the spirit and the letter of the international drug conventions. Although, the rationale, processes and outcomes of policy change were distinctive in many regards, this chapter posits that there are conceptual resemblances. In both countries, the leadership of a charismatic and idiosyncratic president has to be considered. Furthermore, in both countries, mobilisation and activism were also decisive. Lastly, in both countries novel drug policy responded to specific problems that decision-makers faced. Approaching drug policy reforms in Bolivia and Uruguay in terms of personal leadership, mobilisation and policy problems provides a useful analytical first-cut to assess the continuity and change in drug policy observable elsewhere. Additionally, scrutinising the reasons and motivations for undertaking drug policy reform also allows to better understand each country’s behaviour on the international stage.
