Abstract
The current depletion of fossil fuels and environmental degradation are requiring greater energy efficiency in buildings, particularly in the residential sector. However, environmental improvement actions for dwellings are usually based on general considerations, without identifying the most appropriate measurements to be taken in each case, or reviewing their application with stakeholders. This article puts forward a strategy to propose effective and feasible modifications in the design or refurbishment of single-family homes to reduce energy use while maintaining indoor comfort. The improvements proposed are based on dynamic energy simulations of individual models adapted to local realities that can be carried out by regular professionals. The process includes the review of studies and information on the geographic area, and compilation of the constructive features and occupancy data of each house to create a proper energy behaviour model. Possible improvements to the building are then simulated separately in each model and the results recorded. Subsequently, a budgetary analysis of these alternatives according to construction costs and financial projections is carried out in order to identify retrofit packages and consult the opinions of residents and builders. The application of this strategy is demonstrated in the study of several houses in Concepción, Chile, where different sets of measures have been identified to achieve high reductions in energy demand while having low cost and being highly appreciated by the participants. This provides a methodology for developing and validating effective solutions for the environmental improvement of existing dwellings and new housing projects.

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.

Abstract
Purpose
The purpose of this paper is to study the dynamic characteristics and seismic performance of the composite open-web grid floor structure.
Design/methodology/approach
Studied by using mode-superposition response spectrum method and time history analysis method.
Findings
The results show that the vertical mode-superposition response spectrum method is close to the time history analysis method. The floor has strong seismic performance, and the deflection and internal force are not large under vertical seism. The vertical seismic action suggested that 10% of the representative value of gravity load should be used to ensure the safety of the structure.
Originality/value
In the design, the mid-span section should be properly strengthened or the variable section design should be adopted.

Abstract
Purpose
The purpose of this study is to assess the state at which lean and six sigma (LSS) are used as a management system to improve the national health system national health system of Mexico.
Design/methodology/approach
Cross-sectional survey-research. The survey was administered at 30 different hospitals across six states in Mexico. These were selected using convenience sampling and participants (N = 258) were selected through random/snowball sampling procedures, including from top managers down to front-line staff.
Findings
Only 16 per cent of respondents reported participation in LSS projects. Still, these implementations are limited to using isolated tools, mainly 5s, failure mode and effects analysis (FMEA) and Fishbone diagram, with the lack of training/knowledge and financial resources as the top disabling factors. Overall, LSS has not become systematic in daily management and operations.
Research limitations/implications
The sampling procedure was by convenience; however, every attempt was made to ensure a lack of bias in the individual responses. If still there was a bias, it is conjectured that this would likely be in overestimating the penetration of LSS.
Practical implications
The penetration of LSS management practices into the Mexican health system is in its infancy, and the sustainability of current projects is jeopardized given the lack of systematic integration. Hence, LSS should be better spread and communicated across healthcare organizations in Mexico.
Originality/value
This is the first research work that evaluates the use of LSS management practices in a Latin American country, and the first journal paper that focuses on LSS in healthcare in Mexico.

The purpose of this paper is to provide evidence about the effects of the MILA agreement in terms of improving financial market efficiency.
Abstract
Purpose
The purpose of this paper is to provide evidence about the effects of the MILA agreement in terms of improving financial market efficiency.
Design/methodology/approach
The authors measure efficiency by studying the stock reaction to earnings announcements using a conditional heteroscedasticity generalized autoregressive conditional heteroscedasticity-adjusted market model and the most commonly implemented event study tests for 3,399 events across four countries in the Latin American Integrated Market (MILA).
Findings
Contrary to expectations, the results show that the MILA agreement has isolated gains in terms of reaction to corporate earnings announcements, which translates into partial improvements in market efficiency. However, the evidence indicates that the MILA agreement favored cointegration, which is in line with other studies.
Practical implications
This paper provides evidence for policymakers and regulators that a stock market agreement is a condition that promotes market cointegration, but it is not an element that in itself ensures an improvement in market efficiency. To achieve greater MILA benefits, regulatory and market-level changes are required.
Originality/value
This is the first study that analyses the effect of a stock market agreement on the efficiency of markets, expanding on what has been studied in the finance literature regarding the influence of these agreements on cointegration.
Propósito
Esta investigación entrega evidencia sobre los efectos del acuerdo MILA respecto a mejoras en la eficiencia de los mercados accionarios involucrados.
Diseño/metodología/enfoque
Medimos eficiencia estudiando la reacción de los mercados accionarios tras anuncios de resultados utilizando un modelo de mercado ajustado por heteroscedasticidad condicional (GARCH). Además, consideramos las pruebas de estudios de evento más utilizadas en la literatura para 3,399 eventos en los 4 países involucrados en el acuerdo MILA.
Resultados
Contrario a lo esperado, los resultados muestran que el acuerdo MILA genera aumentos marginales en la reacción frente a anuncios corporativos, lo cual se traduce en mejoras parciales de la eficiencia de mercados accionarios. Sin embargo, la evidencia muestra que el MILA sí favorece a la cointegración, lo cual va en línea con estudios previos.
Implicancias prácticas
Esta investigación entrega evidencia para reguladores de que un acuerdo de integración bursátil promueve cointegración entre mercados, pero no es un elemento que por sí solo asegure una mejora en eficiencia. Para alcanzar mayores beneficios del acuerdo MILA, se requieren cambios adicionales a nivel de mercado accionario y de regulación.
Originalidad/valor
Este es el primer estudio que analiza el efecto de un acuerdo de integración bursátil en la eficiencia de los mercados accionarios, expandiendo lo que ha sido ya encontrado en la literatura financiera respecto a la influencia de estos acuerdos en cointegración.

Abstract
The relevance of entrepreneurship in the economic systems of the regions is well documented. Recently, a new concept has emerged in the entrepreneurship literature, entrepreneurial ecosystem (EE), to analyze the dynamics of a given territory and its outputs and impact upon entrepreneurship. Moreover, it is also well documented the close relationship between entrepreneurship and family business (FB). Keeping in mind the multidimensionality of the latter, its scholars are beginning to look into the entrepreneurial elements embedded in the family processes and the influence of context.
After an extensive literature review made, a significant gap was found, given the historical relevance that FB (SMEs the vast majority) have in the global economic systems. A FB entrepreneurial ecosystem (FBEE) model is proposed based on the data collected from two case studies, on Portugal's wine industry, and Mexico's shoe industry, both artisan industries confronted with the urge to reinvent and adapt to face deep market and industry changes.
The results should indicate the feasibility of proposing a second level on the theory of EE, the FBEE, where both the family and business itself ultimately play a vital role in its success and impact the whole system.

Abstract
Purpose
Through the Belt and Road Initiative (BRI), China has built bilateral relations with Latin American states. The purpose of this article is to explore the potential for using the Pacific Alliance (PA) as a negotiating frame as regards the Belt and Road Initiative.
Design/methodology/approach
We use a descriptive and analytical methodology to recapitulate and analyze the factual and normative background of Latin American economic integration during the last three decades, a process that so far has culminated in the Pacific Alliance (PA) and an emphasis on the Asia–Pacific region.
Findings
We contend that the PA has been a learning process in terms of economic cooperation. In addition, it is a Latin American economic integration project that emphasizes its focus on the Asia–Pacific region. Considering the nature of BRI projects, as well as Latin American states’ and China’s interests, we contend that it would be beneficial if Chile, Colombia, Mexico, and Peru, the members of the PA, and China channeled their BRI relations through the PA. Thus, the PA should be China’s negotiating partner.
Originality/value
So far, the Belt and Road Initiative (BRI) in Latin America has been built upon bilateral relations. This article explores the possibility of developing the BRI through the Pacific Alliance (PA).

Abstract
Previously disregarded factors are now included in development theory and practice. A narrow understanding of capital has had profound effects on development as well as on tourism policy and governance. In this framework, purpose-designed tourism for development has been the exception. Contemporary ideas of other forms of capital playing a key role in a broader concept of development are examined, specifically the central function of human and social-institutional capital. Human capital is seen in the light of capabilities, attributes, and knowledge possessed by individuals. Social-institutional capital may empower individuals as it refers to the value of trust and cooperation deriving from formal and informal sets of behavioral rules. This chapter clarifies the foundations of tourism as an instrument for development if tourism policy and governance are designed and implemented within an adequate framework.

Abstract
Purpose
This paper reviews the origins of the Ethics Council of the Federation of Social Communication Media of Chile (1991-2019) and looks into the historical circumstances surrounding its creation, the concept of self-regulation as understood by its founders, and the criteria that initially ruled its operation.
Design/methodology/approach
A qualitative survey of nine contemporary witnesses and the confrontation with the scientific literature.
Findings
The results reveal a significant coincidence with the academic literature both in the description of the concept of self-regulation and in the origin of the ethics councils and of the system under which they operate. However, a series of nuances not usually considered in the concept of self-regulation are described.
Originality/value
This study will help assess the national and international possibilities of self-regulation and the significance of the Chilean ethics council.
