This study aims to propose a decision support system (DSS) for maintenance management of a service system, namely, a street cleaning service vehicle. Referring to the information flow management, the blockchain technology is integrated in the proposed DSS to assure data transparency and security.

The DSS is designed to efficiently handle the data acquired by the network of sensors installed on selected system components and to support the maintenance management. The DSS supports the decision makers to select a subset of indicators (KPIs) by means of the DEcision-MAaking Trial and Evaluation Laboratory method and to monitor the efficiency of performed preventive maintenance actions by using the mathematical model.

The proposed maintenance model allows real-time decisions on interventions on each component based on the number of alerts given by sensors and taking into account the annual cost budget constraint.

The present paper aims to highlight the implications of the blockchain technology in the maintenance field, in particular to manage maintenance actions’ data related to service systems.

The proposed approach represents a support in planning, executing and monitoring interventions by assuring the security of the managed data through a blockchain database. The implications regard the monitoring of the efficiency of preventive maintenance actions on the analysed components.

A combined approach based on a multi-criteria decision method and a novel mathematical programming model is herein proposed to provide a DSS supporting the management of predictive maintenance policy.

This paper aims to contribute to a better understanding of the origins of Spanish public relations from the end of the nineteenth to the early twentieth century. Although the term “public relations” was an export to Europe by the end of the second world war (with some exceptions), its philosophy had already been practised in some countries, and countries not always under a democratic regime, as the Spanish case shows.

The approach taken is a literature review of the first Spanish communication journals, oral interviews with the pioneers in the field and documentary research of the unpublished professional archive of the first Spanish agency, established in 1960.

The first “public relations” campaigns did not appear until the very late 1950s. However, a closer look reveals the existence of precedents in the first half of the century though under other names such as “educational” and “prestige” advertising, or “propaganda” campaigns. Despite being considered as isolated experiences, they prove the phenomenon precedes the name of “public relations”.

This paper places special emphasis on two lines of emergence for public relations. First, the profession in Spain naturally evolved and stemmed from advertising and, due to historical reasons, it was also related to communicative initiatives known as “propaganda”. Second, once the practitioners heard about the American term “public relations”, the precedents seemed to be ignored and were replaced by the influence of other countries' experiences, thanks to the wide vision of the pioneers.

There is little research on the origins of public relations in Spain and none on the precedents. This paper fills in some of the gaps.

In this paper, we analyze the heterogeneity of acquisition integration processes. Starting with the integration types laid down by Haspeslagh and Jemison (1991), we describe integration processes in terms of their integration level and their integration style. We analyze the postacquisition consequences of integration choice in terms of organizational management analysis, employee turnover, and communication and socialization problems. In a sample of 74 Spanish acquisitions, we demonstrate that management choices about integration level and integration style explain the more relevant consequences of the integration process. They have different consequences in terms of organizational management analysis, employee retention, and communication and socialization.

This article examines the mostly neglected anti-Chinese movement that, supported by Mexico's official post-revolutionary party, persecuted and finally expelled a large majority of Mexico's Chinese community. The article analyzes the trajectory of this racial movement from its origins as a social and political movement to its incorporation within the new orthodoxy of the post-revolutionary state. In particular, it examines the relevance of anti-Chinese racism and ideology for the resolution of the hegemonic struggle between the two dominant Sonoran caudillos Plutarco Elias Calles and Alvaro Obregón. Secondly, it considers the importance of anti-Chinese ideology and actions for the creation of consent in the “unstable equilibrium” that shaped Mexican politics between 1928 and 1934. Finally, this article examines the epistemological compatibility between anti-Chinese ideology, the “cultural revolution” of Mexico's post-revolutionary regimes, and the racial understandings and sentiments of the mestizaje theories informing Mexican revolutionary nationalism. The article suggests that a reconsideration of race offers a better theoretical understanding of Mexican state formation and the cultural processes through which social identities take form in interaction with the state, its institutions and discourses. The treatment of race as a political problem also contributes to a better understanding of the mechanisms and processes that transform diffuse racial sentiments, perceptions and expectations into militant and politically organized racial movements.
