Abstract

Purpose

The purpose of this paper is to develop a load detection method for domestic induction cooktops. The solution aims to minimize its impact in the converter power transmission while enabling the estimation of the equivalent electrical parameters of the load. This method is suitable for a multi-output resonant inverter topology with shared power devices.

Design/methodology/approach

The considered multi-output converter presents power devices that are shared between several loads. Thus, applying load detection methods in the literature requires a halt in the power transfer to ensuring safe operation. The proposed method uses a complementary short-voltage pulse to excite the induction heating (IH) coil without stopping the power transfer to the remaining IH loads. With the current through the coil and the analytical equations, the equivalent inductance and resistance of the load is estimated. The precision of the method has been evaluated by simulation, and experimental results are provided.

Findings

The measurement of the current through the induction coil as a response to a short-time single-pulse voltage variation provides enough information to estimate the load equivalent parameters, allowing to differentiate between no-load, non-suitable IH load and suitable IH load situations.

Originality/value

The proposed method provides a solution for load detection without requiring additional circuitry. It aims for low power transmission to the load and ensures zero-voltage switching and reduced peak current even in no-load cases. Moreover, the proposed solution is extensible to less complex converters, as the half bridge.

Abstract

Purpose

The purpose of this paper is to present a project called EmprendeSport, whose aim is to increase knowledge in entrepreneurship and sports in students, professors and professionals through seminars carried out from 2015 to 2018. This study summarises the experience and data extracted throughout these seminars with the purpose of helping to design policies that stimulate business activity of the universities that seek to promote entrepreneurial spirit within a higher educational context.

Design/methodology/approach

This is a descriptive paper of the experiences of the seminars done during four years, with a regularly assistance of 200 people. The profile of the assistants was, mainly males, studying a degree on sports or entrepreneurship and working.

Findings

There is a lack of knowledge and interest in entrepreneurship. The realisation of the seminar resulted to be a useful incentive for the public to develop new ideas to innovate in their daily lives, some of them also, because of the seminar through of creating their own business. From the organisation perspective, in order to increase the entrepreneurial culture between the females.

Originality/value

The main contribution of this document could be to help design policies that stimulate business activities of universities and, therefore, stimulate their contribution to the development of the modern knowledge economy.

Abstract

Purpose: The first objective is to explore how narcotelenovelas and news can be compared in their representation of drug violence and figures. The second is to explore a method which identifies intertextual references in fiction by contrasting them with journalistic reports. Methodology/approach: Qualitative content analysis is of three narcotelenovelas: El Señor de los Cielos, El Chapo, and Narcos: México. After documenting clear historical references and figures, a search was made through news engines and portals to make a comparison of the fictional versus journalistic representation of such references. Findings: Many elements of narcotelenovelas such as events and public figures are highly comparable to those described in news. While producers openly warn that they changed facts for dramatic purposes, it’s possible to propose hypotheses in which audiences construct their historical memories based on fictional narratives. Research limitations: This chapter does not offer an exhaustive list of intertextual references from all three narcotelenovelas. Originality/value: This type of comparative analysis between fiction and journalism hasn’t been explored for the study of narcoculture media products. The author poses a hypothesis, in which fiction contributes significantly to collective memories and imaginaries, especially when it appeals to historical references audiences might identify.

Abstract

The multipolar configuration of the current economic context has led management scholars to reconsider the existing theoretical perspectives that explain drivers and effects of mergers and acquisitions (M&As).

The combination of structures, systems, processes and people imposed by M&A is a complex process that needs to be properly managed. This process can be divided into three phases of pre-combination, combination and post-combination. It evidences the dilemma of integrating two distinct firms and preserving their specific identities. In cross-border M&A, differences in organizational cultures increase the complexity of the integrative process and make it difficult for the companies that proceed to the merger to reach the preordained synergies, where the problem linked to the diversity of the national culture is added. A successful integration process allows to treat the elements of diversity as opportunities and not as obstacles.

Abstract

Purpose

The purpose of this paper is to explore the relationship between the ability, motivation and opportunity model, and organisational citizenship behaviour (OCB) as a result variable, using the perceived organisational support (POS) as a moderator of this relationship.

Design/methodology/approach

The hypotheses developed here are tested using data from a sample of Spanish firms belonging to two industries: finance and hotels. These sectors were selected due to the serious impact the recent financial crisis had on them, and because they may benefit from extra-role behaviours.

Findings

The results reveal that ability and motivation significantly influence the level of OCB. POS also has a notable direct effect on OCB, as well as moderating in the relationship between opportunity and OCB.

Originality/value

The study’s findings have some important lessons for practitioners and researchers with an interest in OCB, showing how to improve these extra-role behaviours, which can be so necessary in this post-crisis context.

Abstract

The PMI Risk Framework (PRF) is introduced as a guide to classifying and identifying risks which can be the source of post-merger integration (PMI) failure — commonly referred to as “culture clash.” To provide managers with actionably insight, PRF dissects PMI risk into specific relationship-oriented phenomena, critical to outcomes and which should be addressed during PMI. This framework is a conceptual and theory-grounded integration of numerous perspectives, such as organizational psychology, group dynamics, social networks, transformational change, and nonlinear dynamics. These concepts are unified and can be acted upon by integration managers. Literary resources for further exploration into the underlying aspects of the framework are provided. The PRF places emphasis on critical facets of PMI, particularly those which are relational in nature, pose an exceptionally high degree of risk, and are recurrent sources of PMI failure. The chapter delves into relationship-oriented points of failure that managers face when overseeing PMI by introducing a relationship-based, PMI risk framework. Managers are often not fully cognizant of these risks, thus fail to manage them judiciously. These risks do not naturally abide by common scholarly classifications and cross disciplinary boundaries; they do not go unrecognized by scholars, but until the introduction of PRF the risks have not been assimilated into a unifying framework. This chapter presents a model of PMI risk by differentiating and specifying numerous types of underlying human-relationship-oriented risks, rather than considering PMI cultural conflict as a monolithic construct.

Abstract

We analyze how entry order in a new field influences the stock market reaction to strategic alliances and acquisitions aimed at expanding firm boundaries. We argue that alliances would be more valued by investors at the early stages of a process of convergence between two markets, whereas acquisitions would be more valued in the later stages. Using a sample of alliances and acquisitions carried out by European telecom firms, our hypotheses have been confirmed.

Abstract

Acquisition integration is important to realize synergies and to achieve acquisition success. However, there is a lack of clarity on pertinent integration approaches suggesting that integration is more complex and dynamic than traditionally assumed. In this chapter, we shed light on ambiguous cause effect relationships by investigating the effect of integration related decisions on intermediate goals. Additionally, we argue that entrepreneurial integration skills, or proactivity under ambiguity, are needed to keep pace with the dynamism inherent in acquisition integration. Based on primary data on 116 acquisitions, we find that entrepreneurial integration skills can display both advantages and disadvantages. While it helps to realize expected and serendipitous synergies, it can also trigger employee uncertainty due to decreased transparency. In supplementary analysis, we show measures to outperform with various integration approaches. Implications for management research and practice are identified.

Abstract

This chapter examines the training of indigenous Mayan catechists by the Roman Catholic Diocese of San Cristóbal de Las Casas in Chiapas, Mexico, and their subsequent role in the establishment and growth of the Ejercito Zapatista de Liberación Nacional (EZLN) in the period prior to the Zapatistas' 1994 uprising. It considers the adequacy of Timothy Wickham-Crowley's model of guerrilla insurgencies in Latin America in explaining the Zapatista case. It finds, contrary to Wickham-Crowley's model of the relations between urban university leadership groups and peasant support bases, that the catechists constituted a stratum of “organic indigenous-campesino intellectuals” that radically undermined their communities’ traditional intellectual dependence on outsiders and enabled them to constitute themselves as a new collective political subject.
