Strain sensing characteristic of carbon nanotubes has been established in the past at nanoscale. In this study, it is shown that the carbon nanotube film sensors, made up of randomly oriented carbon nanotubes, can be used as strain sensors at macro level. A nearly linear trend between the change in voltage, measured using a movable four point probe, and strains, measured using conventional electrical strain gage, indicates the potential of such carbon nanotube films for measuring flexural strains at macro level. Isotropic strain sensing capability of the carbon nanotube film sensors, due to randomly oriented carbon nanotubes, allows multidirectional and multi‐location measurements.

The purpose of this paper is to focus on the Festival Internacional Cervantino, which represents one of the major cultural events in Latin America. Based on theoretical propositions regarding tourism as an experience, perception of visitors was studied focussing on emotional factors. Urban perception was also addressed, especially where public service failure affected the experience and therefore, the placemaking.

A mixed methodology was applied. First, the event experience scale (EES) methodology for visitors’ perception was performed in order to collect data directly from tourists. The relationship between the festival and the visit to heritage resources and attractions was especially highlighted and analysed. Urban field work focussed on expressing the location of the most visited areas during festival days. Public services were also assessed where perception was affected negatively. Interviews were applied to public administration officials and public policy-related documents were collected in order to understand the expectation of visitors, previous to the experience itself. Local perception was also contrasted with the rest of the data.

Attracted by information about the historic and colonial nature of the city, tourists gather massively in Guanajuato during the festival. This event in particular yields in some aspects to a transient placemaking, mainly related to inner perception and the event as such is highly appreciated. It was also found that the foreign figure of Cervantes was incorporated into the intangible heritage discourse of the city and linked to the event itself. However, some urban spaces and services need improvement to consolidate a positive experience of visitors who complain about specific factors such as traffic, accessibility, waste disposal and environmental noise.

The fact that the event has caused some problems in a number of urban aspects suggests that new policies might be proposed in order to fill these gaps, especially by the corresponding government agencies. Another issue relates to the concentration of the economic profits and its lack of distribution, which right now does not contribute to social sustainability, yet the event demands high actions and costs to the city and local people.

The research has been useful to give another point of view to existing surveys and conclusions of the impact of the festival. The application of EES has yielded some improvements that could be made in further applications of the same methodology. Application of EES to assess the impact of events in urban spaces and services can be applied to many other cities that host festivals in their city centres.

The purpose of this article is to summarize the basic literature and concepts of innovation and entrepreneurship, emphasizing the relevant studies for Latin America. The authors aim to assess the role of Latin America in the world innovative activity utilizing the production of USPTO patents.

To achieve the first objective, the authors review and summarize the relevant literature for innovation and entrepreneurship in Latin America. They also introduce each of the papers included in the current special issue of Academia. To achieve the second objective, the authors use the production of USPTO patents by Latin American residents, and examine those levels to the rest of the world.

The authors find Latin America to be a marginal contributor to the world innovative activity. Although the region represented 8.7 per cent of world GDP in 2011, it only generated 0.19 per cent of the world patents registered at the USPTO between 2008 and 2012, and only 0.17 per cent of all patents registered since 1976. However, countries such as Costa Rica and Uruguay have larger levels of patent production by 100,000 inhabitants with 7.05 and 4.72 for 1976-2012.

This introduction introduces work that continues the intense discussion on innovation and entrepreneurship in Latin America. It is to the extent of the authors' knowledge, one of the first attempts to measure the level of innovation at the regional level, and compare the performance of different countries. This special edition has implications for individuals, firms and governments striving to introduce new products, services and processes in a region that has historically confronted important barriers to innovation.

En esta introducción presentamos algunos conceptos básicos sobre innovación y empresariado, y hacemos énfasis en la literatura que ha estudiado estos fenómenos en América Latina. Evaluamos, además, el papel de América Latina en la actividad innovadora mundial, utilizando la producción de patentes registradas en la Oficina de Patentes y Marcas de Estados Unidos (USPTO), y encontramos que América Latina desempeña un papel marginal con relación a otros centros mundiales de innovación. Finalmente, se presentan los artículos de este número de la revista Academia. Esta edición especial tiene implicaciones prácticas para individuos, empresas y gobiernos, que quieran introducir nuevos productos, servicios, y procesos desde una región que históricamente ha tenido que enfrentar barreras a la innovación.

The purpose of this paper is to determine the effect of the chosen search engine results page (SERP) on the website-specific hit count estimation indicator.

A sample of 100 Spanish rare disease association websites is analysed, obtaining the website-specific hit count estimation for the first and last SERPs in two search engines (Google and Bing) at two different periods in time (2016 and 2017).

It has been empirically demonstrated that there are differences between the number of hits returned on the first and last SERP in both Google and Bing. These differences are significant when they exceed a threshold value on the first SERP.

Future studies considering other samples, more SERPs and generating different queries other than website page count (<site>) would be desirable to draw more general conclusions on the nature of quantitative data provided by general search engines.

Selecting a wrong SERP to calculate some metrics (in this case, website-specific hit count estimation) might provide misleading results, comparisons and performance rankings. The empirical data suggest that the first SERP captures the differences between websites better because it has a greater discriminating power and is more appropriate for webometric longitudinal studies.

The findings allow improving future quantitative webometric analyses based on website-specific hit count estimation metrics in general search engines.

The website-specific hit count estimation variability between SERPs has been empirically analysed, considering two different search engines (Google and Bing), a set of 100 websites focussed on a similar market (Spanish rare diseases associations), and two annual samples, making this study the most exhaustive on this issue to date.

Since first small personal exposimeters became available, some studies have characterized personal exposition to radio frequency electromagnetic fields. The effect of body and relative position of the exposimeter have been also analyzed but some questions are still unanswered. The paper aims to discuss these issues.

Using three personal exposimeters in four different subjects, the authors characterized and compared measurements in a controlled experiment.

The authors found statistically significance differences between exposimeters and subjects due to relative position (right and left) and a control position far from the body (center). It should indicate that body and relative position of the exposimeter affect directly to the measurement, conditioning final and average results.

Measurements using personal exposimeters have to be reconsidered and controlled.

The authors test personal exposimeters limitations in real conditions.

This paper provides an overview of the Aztec 13 – the top 13 multinational enterprises in Mexico. Different from research that groups countries and regions, the purpose of the paper is to deliver a nuanced picture of these multinationals in terms of their key characteristics and the strategies they follow when they internationalize.

All data sources that have been identified and reviewed are documents, printed and electronic. The Aztec multilatinas were identified using Forbes Global 2000 (2017). Other data sources such as media texts, company annual reports, reports filed with the Mexican Stock Exchange and the US Securities and Exchange Commission, as well as investor presentations, were collected and analyzed. Data sources were published in English and Spanish. The analytic procedure adopted entailed identifying, selecting, making sense of and synthesizing the data contained in the documents.

Aztec multilatinas have specific characteristics which, to a great extent, influence their internationalization strategies. Characteristics include the geographical location of their headquarters, their origin and history, their ownership structure and ties with families and government. These factors, combined, help to describe in greater nuance the internationalization strategies and activities of the Aztec 13. Such a detailed and focused description is a first necessary step for subsequent potential theorizing.

This paper contributes to the vibrant scholarly conversation on multinational enterprises from less researched regions and countries. Latin America is such a region and Mexico is such a country. Focusing on a single country and its top 13 multinationals allow a comprehensive description and disciplined analysis, with no dangerous generalizations to large regions and even larger settings such as emerging markets multinationals and with no false claims for theorizing.

This study aims to examine the use of the metaverse in tourism and hospitality to comprehend better how the technology might shape customer journey management, especially relative to information provision, experiences and customer benefits.

This explanatory research used a two-stage approach of media analysis and practitioner interviews to analyse the interactions among tourism information provision, customer experiences and customer benefits in the metaverse. It conceptualized and mapped the consumer journey of the emerging metaverse experience, focusing on the ideas and practices of metaverse design pioneers in tourism and hospitality.

Based on the media analysis and interviews with 27 designers, the metaverse – information – experiences – benefits (MIEB) model was proposed, containing three parts (information characteristics, customer experiences and customer benefits) and 31 supporting items grouped into nine components.

One of the unique contributions of this research is the MIEB model for applying the metaverse in customer journey management (pre-, during- and post-trip). The findings contribute to the current literature with this model based on the practical perspectives of metaverse designers and provide insights on how to incorporate the MIEB model in applying the metaverse in tourism and hospitality management. The findings also address existing literature gaps of insufficient research on metaverse management and design through all stages of the customer travel journey and by paying attention to stakeholders’ viewpoints, including the media and designers of metaverse applications. Engaging in semi-structured interviews with pioneers of the metaverse to gain insights into the design of tourism experiences was also different from other metaverse tourism research, although this is not claimed as a significant point of innovation.

While the literature has focused on the benefits granted by Deferred Action for Childhood Arrivals to undocumented youths in the USA, the purpose of this paper is to focus on the challenges encountered during the application process.

This paper is based on 60 semi-structured interviews with Latino undocumented youths living in the New York City and northern New Jersey metropolitan area.

The policy was intended to improve the inclusion of some undocumented youths in the USA by temporarily shielding them from deportation and providing them with a social security number. Analyses indicate great variation in youths’ experiences while applying for DACA, including program knowledge, financial impact, and application assistance – some of which was alleviated by respondents’ political engagement. This paper shows that participants suffered from anxiety due to the manner of implementation of the program.

This research is based on the self-disclosure of participants as undocumented youths. Fieldwork also took place in the New York/New Jersey metropolitan area, which is traditionally considered as more “immigrant-friendly” context than other areas of the USA.

This paper provides much needed information on the ways in which undocumented youths navigate the federal immigration system and the anxiety associated with it. This paper demonstrates the possibility that a federal policy whose goal is inclusionary could be implemented at the local level in such a way as to promote anxiety and alienation. It also highlights the role of political engagement in shaping immigrant youth’s experiences in the USA.
