Provide tribological information about the applicability of multi‐layer carbon‐chromium composite coatings to gears. Discuss the protection provided against scuffing failures, wear and the influence on gear power losses.

Several screening tests, such as Rockwell indentations, ball cratering, pin‐on‐disc and reciprocating wear tests, were performed in order to evaluate the adhesion to the substrate and the tribological performance of the carbon/chromium composite coating. Afterwards, twin‐disc tests were performed at high contact pressure and high slide‐to‐roll ratios to confirm the good adhesive and tribological properties of the coating under operating conditions similar to those found in gears. Gear tests were performed in the FZG machine in order to evaluate the anti‐scuffing performance of the carbon/chromium coating using additive free gear oils. Finally, the carbon/chromium composite coating was also applied to the gearing in a gearbox and its influence on the gearbox efficiency was analysed.

The C/Cr has got very good adhesion to the steel substrate, provides low friction coefficients between contacting solids in relative movement, gives excellent protection against scuffing and wear reduction in gears, and promotes a slight improvement of the gears efficiency.

The protection of this carbon/chromium coating against gear micro‐pitting should be investigated.

This study confirms the applicability of this coating to industrial gear applications, especially in two particular applications: severe applications involving high contact pressures and high sliding, frequent start‐ups and inefficient lubrication; and acting as tribo‐reactive material and substituting non‐biodegradable and toxic additives in environmental lubricants.

This work validates and quantifies the influence of this C/Cr multi‐layer composite coating in gear applications in terms of adhesion to the substrate, anti‐scuffing performance and efficiency.

This teaching case aims to analyze the business model of Amaro, a company that directly sells lifestyle goods to end consumers (B2C), focused on the women's market. Amaro's original business model is introduced and a challenging dilemma is proposed: could Amaro innovate its business model, moving from a digitally native vertical brand (DNVB)-type company to a platform, specifically a vertical marketplace focused on the female audience? Would Amaro be prepared for this evolution or would it be more appropriate to focus on or strengthen the DNVB model?

This teaching case was developed based on in-depth interviews with Amaro's leadership. The teaching notes were proposed based on business model innovation, competitive positioning and market trends concepts. The teaching case considers a new type of business model called DNVB. Students can review the concepts, create analyses and recommend which strategic options can leverage the company for a new growing cycle.

Using the case study in the classroom should promote the discussion and reflections on business model innovation and the future of retail in omnichannel contexts - Amaro offers products online (on an e-commerce platform and native mobile applications) and physically in locations called guide shops. The authors suggested the adoption of frameworks and tools (e.g. the competitive positioning map to allow students to visualize ways to compare strategies and make decisions).

The case introduces a fictional dilemma related to the decision to maximize offline or online investments or completely change the company's business model by adding a new vertical marketplace approach.

This teaching case contributes to the student's learning about business model innovation and evolution. Case discussions could explore contemporary concepts such as value proposition, disintermediation and omnichannel commerce.

Offering goods directly to the consumers by using modern technological architecture through vertical integration within the supply chain makes the DNVB business model an original topic in the start-up segment.

In light of the growing interest in neuroscience within the managerial and organizational cognition (MOC) scholarly domain at large, this chapter advances current knowledge on core neuroscience methods. It does so by building on the theoretical analysis put forward by Healey and Hodgkinson (2014, 2015), and by offering a thorough – yet accessible – methodological framework for a better understanding of key cognitive and social neuroscience methods. Classifying neuroscience methods based on their degree of resolution, functionality, and anatomical focus, the chapter outlines their features, practicalities, advantages and disadvantages. Specifically, it focuses on functional magnetic resonance imaging, electroencephalography, magnetoencephalography, heart rate variability, and skin conductance response. Equipped with knowledge of these methods, researchers will be able to further their understanding of the potential synergies between management and neuroscience, to better appreciate and evaluate the value of neuroscience methods, and to look at new ways to frame old and new research questions in MOC. The chapter also builds bridges between researchers and practitioners by rebalancing the hype and hopes surrounding the use of neuroscience in management theory and practice.

The paper aims to explore how companies communicate their heritage by drawing on heritage marketing and corporate communications literature and mapping the corporate heritage communication strategies of iconic Italian brands.

The study adopts an inductive multiple case study approach, analysing the communication of corporate heritage by nine iconic Italian brands (Pastificio Lucio Garofalo, Barovier & Toso, Pasta Farina, Ducati, Amaro Montenegro, Fiat, Bonomelli, Olivetti and Illy).

In communicating corporate heritage, companies adopt different strategies that vary along two main dimensions – the subject of the story and the tone of voice of the content. The strategies are: (1) heritage for authenticity; (2) heritage for market leadership; and (3) heritage for continuity.

From a theoretical point of view, the study highlights that heritage marketing strategies vary according to underlying strategic themes and narrative approaches. From a managerial point of view, it offers a preliminary guide for the development of corporate heritage communications, also providing indications for their implementation.

This study is amongst the firsts to investigate the strategic antecedents that can shape corporate heritage communication strategies. It represents an integration of the existing literature, which is limited to the descriptive presentation of heritage marketing principles and tools.

With the diffusion of innovation theory (DOI) and theory of planned behaviour (TPB) as the guiding theoretical perspectives, this research aims to identify the factors motivating user attitudes and in-app purchase intentions (IAPIs). The moderating impact of user inertia towards TPB constructs was also explored.

A total of 500 responses were received via an online survey fielded from July to October 2021. The data were then analysed using partial least square structural equation modeling (PLS-SEM).

The results indicated that attitudes towards travel app shopping were predominantly determined by perceived relative advantages, compatibility and complexity. Findings also suggested that IAPIs are positively influenced by attitudes, communicability and perceived behavioural control and are moderated by user inertia.

A holistic framework integrating theoretical foundations from two disciplines (information systems and psychology) was designed to explain factors motivating user intentions to purchase travel products and services from apps. This research found a missing link in previous studies by showing the indirect role of attitudes that bridges the DOI and TPB and the importance of inertia as a key boundary condition.

Compras de aplicaciones de viajes en los móviles: Comprendiendo los factores de éxito que influyen en las intenciones de compra de las aplicaciones de viaje

Resumen

Con la teoría de la difusión de la innovación (DOI) y la teoría del comportamiento planificado (TPB) como perspectivas teóricas de análisis, esta investigación identifica los factores que motivan las actitudes de los usuarios y las intenciones de compra dentro de las aplicaciones. También se exploró el impacto moderador de la inercia del usuario hacia las construcciones TPB.

Se recibieron un total de 500 respuestas a través de una encuesta en línea realizada entre julio y octubre de 2021. Los datos se analizaron utilizando el modelo de ecuaciones estructurales de mínimos cuadrados parciales.

Los resultados indicaron que las actitudes hacia la compra de aplicaciones de viajes estaban determinadas predominantemente por las ventajas relativas percibidas, la compatibilidad y la complejidad. Mientras, los hallazgos también sugirieron que las intenciones de compra en la aplicación están influenciadas positivamente por las actitudes, la comunicabilidad y el control del comportamiento percibido, y son moderadas por la inercia del usuario.

Se diseñó un marco holístico que integra los fundamentos teóricos de dos disciplinas (sistemas de información y psicología) para explicar los factores que motivan las intenciones de los usuarios a la hora de comprar en las aplicaciones móviles productos y servicios turísticos. Esta investigación encontró un gap en estudios previos al mostrar el papel indirecto de las actitudes que unen a la teoría de la difusión de la innovación (DOI) y la teoría del comportamiento planificado (TPB), y la importancia de la inercia como una condición límite clave.

Given the growing supply of wines and the large number of new consumers with purchasing power but lacking knowledge of the subtleties of high-quality wines, expert opinions are used for consumers as proxies for quality. This study aims to determine the determinants of prices in top-quality wine market. The authors also seek to estimate the role for country of origin, grape, producing region and winery in prices. And, finally, the authors try to show how countries, regions and wineries can help increase their position in international rankings.

The authors try to answer: What factors explain the price of top-quality wines (defined as best rated in a standardized ranking)? To some extent, in the hands of producers influence prices, which imply long-term decisions or large investments in land and marketing. Other variables that consumer value does affect prices. The authors try also to detect undervalued or overvalued wines, grapes, regions, wineries or producer countries. The authors estimate an econometric model of hedonic prices using a 14-year sample of the Wine Spectator’s 100 top-rated wines for the American market between 2003 and 2016, totaling 1,400 observations. The sample is a great cross-section because each wine is unique.

The authors’ contribution is twofold: the determination of the price explanatory values and the identification and attribution of price differences by country, grape, region and winery. Also, the authors detected grapes, countries, regions and wineries which are overvalued or undervalued with respect to the average prediction of the model.

The findings are useful to understand the role of price explanatory variables, as well as for making policy and managerial decisions. From the model, collective or managerial actions can be derived to increase particular wines’ positions in international rankings. The proxy for “quality” in the study is not the only possible definition.

In some cases, managerial choices could be conditioned by the policies or history. There is some room for collective action and public policies to improve regions’ and countries’ reputation.

There are clear synergies for policies that can raise the prestige of countries and regions and their spillovers on the brand name reputation of individual wineries.

The results, policy and managerial implications are of interest for business, countries interested in improving their position in international rankings and for consumers to make more informed decisions.

This study aims to apply the concept of brand love to a destination and investigate its antecedents and consequences. It also explores the moderating effects of time elapsed since the establishment of the destination brand love relationship on the outcomes of destination brand love.

A total of 5,511 valid responses were obtained from an online survey distributed among former international students from the Erasmus program of the European Union. Partial least squares structural equation modeling was conducted to assess the hypotheses.

Destination brand love was found to have a significant impact on electronic word of mouth (eWOM), WOM, WOM intensity, recommendation and revisit intention. Moderation analysis revealed that the amount of time elapsed since the establishment of the destination brand love relationship did not affect these outcomes. Moreover, destination image and the Erasmus experience had a positive effect on destination brand love.

Destination marketers should focus on enhancing the Erasmus experience and on improving destination image perception, as these factors help develop destination brand love. Marketers should also be aware that this relationship has long-lasting effects.

This study adds to the sparse literature on brand love in relation to a destination. This gives the first results for the importance of Erasmus students to the promotion of a host country. It also contributes to the question of how long the brand love relationship can last.

In light of the controversy between the theoretical importance of financing biotechnology firms’ research and development (R&D), and the firms’ contradictory and ambivalent empirical results, this paper aims to contribute to the debate by providing empirical evidence from Mexico’s case.

The authors use the probit model to determine if firms’ achievements in innovations are related to both private and public financing, and if so, to calculate their marginal effect on the firms’ innovation (n = 40 from 53 firms: 75.5% response). The survey was applied in 2015.

Although a large proportion of the firms innovate and dedicate resources to R&D activities, neither private financing (different from the R&D portion of sales) nor public financing has an impact on innovation activity.

It is necessary to increase the number of studies that corroborate the type of link established between innovations in biotechnology firms and financing. Analyzing the financing/innovation links at various stages of the innovation process would also be relevant.

The research results support the perspective that the theoretical relationship between the financing and achievements of innovation is not conclusive and point to relevant considerations for the public policy agenda of the case study.

The purpose of this study is to examine Airbnb research using bibliometric methods. Using research performance analysis, this study highlights and provides an updated overview of Airbnb research by revealing patterns in journals, papers and most influential authors and countries. Furthermore, it graphically illustrates how research themes have evolved by mapping a co-word analysis and points out potential trends for future research.

The methodological design for this study involves three phases: the document source selection, the definition of the variables to be analyzed and the bibliometric analysis. A statistical multivariate analysis of all the documents’ characteristics was performed with R software. Furthermore, natural language processing techniques were used to analyze all the abstracts and keywords specified in the 129 selected documents.

Results show the genesis and evolution of publications on Airbnb research, scatter of journals and journals’ characteristics, author and productivity characteristics, geographical distribution of the research and content analysis using keywords.

Despite Airbnb having a history of 10 years, research publications only started in 2015. Therefore, the bibliometric study includes papers from 2015 to 2019. One of the main limitations is that papers were selected in October of 2019, before the year was over. However, the latest academic publications (in press and earlycite) were included in the analysis.

This study analyzed bibliometric set of laws (Price’s, Lotka’s and Bradford’s) to better understand the patterns of the most relevant scientific production regarding Airbnb in tourism and hospitality journals. Using natural language processing techniques, this study analyzes all the abstracts and keywords specified in the selected documents. Results show the evolution of research topics in four periods: 2015-2016, 2017, 2018 and 2019.

This study investigated disparities in dual diagnosis (comorbid substance use and depressive/anxiety disorders) among US adults by nativity and racial–ethnic origin and socioeconomic, cultural, and psychosocial factors that may account for the observed disparities.

The study drew on data from two waves of the National Epidemiological Survey on Alcohol and Related Conditions. Racial–ethnic categories included African, Asian/Pacific Islander, European, Mexican, Puerto Rican, and other Hispanic/Latino. Substance use and depressive/anxiety disorders were assessed per DSM-IV. A four-category measure of comorbidity was constructed: no substance use or psychiatric disorder; substance use disorder only; depressive/anxiety disorder only; and dual diagnosis. The data were analyzed using multinomial logistic regression.

The prevalence of dual diagnosis was low but varied by nativity, with the highest rates among Europeans and Puerto Ricans born in US states, and the lowest among Mexicans and Asians/Pacific Islanders. The nativity and racial–ethnic effects on likelihood of having dual diagnosis remained significant after all adjustments.

The limitations included measures of immigrant status, race–ethnicity, and stress and potential misdiagnosis of mental disorder among ethnic minorities.

This new knowledge will help to guide public health and health care interventions addressing immigrant mental and behavioral health gaps.

This study addressed the research gap in regard to the prevalence and correlates of dual diagnosis among immigrants and racial–ethnic minorities. The study used the most current and comprehensive data addressing psychiatric conditions among US adults and examined factors rarely captured in epidemiologic surveys (e.g., acculturation).
