Abstract

Sustainable development challenges have been gaining increased attention from scholars across a wide range of disciplines and governments and business leaders of developed and developing countries. In this chapter, we present selected Latin American socioeconomic indicators, and we note that much progress is needed to achieve the region's many sustainable development goals. We bring forth contributions from different streams of innovation studies for addressing grand challenges, and we discourse on how they push the sustainable development mandate forward. Innovation scholars have highlighted the need to elaborate novel transformational approaches to innovation for addressing such pressing grand challenges. Some scholars have also proposed that while the innovation systems framework is well-suited for addressing sustainable development challenges, it must first be profoundly and radically transformed to account for the novel ways of innovating and integrating a diversity of systemic economic actors and social stakeholders who have conflicting visions, interests, norms, and expectations. We present the different foundational strengths and weaknesses of the innovation systems framework and we discuss the pertinence for its profound and radical transformation. We conclude by organizing these different, yet complementary views of innovation in a conceptual framework while discussing the implications for Latin America and future research.

Abstract

Purpose: Entrepreneurial teams are one of the most crystallized forms of collaboration in the generically collective dynamics underpinning social entrepreneurship. Despite their quantitative prevalence, social entrepreneurial teams (SETs) remain quite absent from the scholarly literature. This chapter aims to develop a research agenda addressing this gap. Methodology/Approach: This chapter first reviews the scarce literature dealing with this subject and develops an operationalizable definition of SETs. Next, it confronts current knowledge on entrepreneurial teams with the specific context of social entrepreneurship to introduce and discuss main topics of investigation on SETs. Findings: Six topics are suggested to have a high potential for developing knowledge on SETs: formation, size and extended team, gender, decision-making and leadership, identity, and turnover. Research Implications: This chapter frames these research avenues within a developmental stages perspective with the aim to contribute to help form and maintain effective SETs. Originality/Value of Chapter: This research has implications for scholars as it defines SETs as a distinct object for research, which allows extending knowledge on collaborative dynamics in social entrepreneurship, but also on entrepreneurial teams in general. The suggested research agenda and its orientation toward the development of effective SETs should be a springboard for future research on this subject.

Abstract

Efforts to contribute to the Sustainable Development Goals are increasingly part of tourism business planning, forming part of their business policies, linking with society and generating a sustainable hotel offer. The great impact it causes and, which in the short term it will achieve, digital tools in hotel activities can be evidenced. It will also help to collect the information that serves for the certifications of hotel companies. In spite of all the efforts, there is still a great knowledge gap that needs to be filled to achieve the expected business results and that it can be evidenced that the hospitality industry is now more than ever focussed on the care of its workers and on contributing to the sustainability of the world.

Abstract

The main objective of this paper is to obtain the duty‐cycle probability forecast functions of cooling and heating aggregated residential loads. The method consists of three steps: first, the single loads are modelled using systems of stochastic differential equations based on perturbed physical models; second, intensive numerical simulation of the stochastic system solutions is performed, allowing several parameters to vary randomly; and third, smoothing techniques based on kernel estimates are applied to the results to derive non‐parametric estimators, comparing several kernel functions. The use of these dynamical models also allows us to forecast the indoor temperature evolution under any performance conditions. Thus, the same smoothing techniques provide the indoor temperature probability forecast function for a load group. These techniques have been used with homogeneous and non‐homogeneous device groups. Its main application is focused on assessing Direct Load Control programs, by means of comparing natural and forced duty‐cycles of aggregated appliances, as well as knowing the modifications in customer comfort levels, which can be directly deduced from the probability profiles. Finally, simulation results which illustrate the model suitability for demand side – bidding – aggregators in new deregulated markets are presented.

Abstract

Purpose

The aim of this paper is to present an approach, able to deal with different models for anisotropy in the finite element method, and how it can be integrated in its formulation.

Design/methodology/approach

This approach is to apply this to the study of power transformers, in which grain‐oriented steel sheets are usually used. In this type of analysis, magnetic characteristics of the steel sheets such as non‐linearity and anisotropy, or even the hysteresis, must be taken into account.

Findings

The Newton‐Raphson method is generally used to solve the system of equations, but it is a CPU‐time‐consuming task, especially when finite element models and circuit equations are coupled and therefore, time is considered in the analysis.

Originality/value

An approach able to deal with different models for anisotropy in the finite element method is presented.

Abstract

Purpose

This paper aims to analyze the possible interdependencies among fiscal, monetary and growth variables by applying multivariate Granger Causality and determining an ultimate “causality path” excluding redundant relationships based on a complex endogenous system for each country.

Design/methodology/approach

We adopt a novel approach to test Granger Causality within the framework of Vector Autoregressive models. This approach enables us to expand the scope of relevant variables, which is typically limited to two or three, previously mentioned. Moreover, we employ graph-theoretic techniques for causal analysis, utilizing the PC algorithm (Colombo and Maathuis, 2014; Spirtes et al., 2000) to determine the optimal causal ordering among all statistically significant relationship.

Findings

Our findings highlight the continued division between “core” and “peripheral” Euro area countries, with monetary policy variables playing a crucial role in the economic growth of “core” nations. Stable inflation contributes to sustained growth in these countries, while fiscal variables contribute to growth across most nations.

Originality/value

The literature concerning the relationship among different macroeconomic variables such as prices, output and monetary policy indicators such as interest rates and interest payments, may be incomplete or misguided due to the exclusion of relevant information because studies are mostly based on a bivariate or a trivariate framework dynamics. In this sense, one goal is the extension of the system, which may be crucial, because the omission of relevant variables may lead to biased results. Furthermore, we apply graph-theoretic methods for causal analysis by using the PC algorithm to determine the ultimate causal sequence among all possible ones and, finally, we aim to understand and disentangle the transmission process and the relationships among economic policies in a Euro area country-level analysis.

Abstract

Purpose

This study illustrates the conceptual framework that expands the knowledge of the fundamental components that describe how AI-driven servant leadership (SEL) influences the job resources (JR), work engagement (WE) and job performance (JP) of tourism and hospitality employees.

Design/methodology/approach

The empirical study was conducted on a sample of 953 international tourism and hospitality employees who were selected via a purposive and snowball sampling approach in a cross-sectional survey. The analysis was performed using a partial least square-structural equation modeling.

Findings

The results of this study confirmed the positive impact of AI-driven SEL on employee JR with the boundary conditions of AI-driven SEL.

Practical implications

This study finding assists tourism and hospitality practitioners in understanding that in the near future, AI will have a major effect on the nature of work, including the impact on leadership styles. Hence, AI-driven SEL holds both positive (through direct impact on JR) and negative (via boundary conditions) impacts on employees’ JP and ultimately organizational success. Accordingly, managers should employ AI-driven SEL to increase employees’ JR, and once employees achieve high WE, they should constrict AI-driven SEL boundary conditions and their influence between JR and WE and WE and JP.

Originality/value

This study offers a novel and original conceptual model that advances AI-driven social theory, SEL theory and job demands-resources (JD-R) theory by synthesizing, applying and generalizing gained knowledge in a methodical way.

Abstract

Purpose

This paper aims to present a comparison of numerical methods for determining the contact pattern of Gleason-type bevel gears. The mathematical model of tooth contact analysis and the finite element method were taken into consideration. Conclusions have been drawn regarding the usefulness of the considered methods and the compatibility of results. The object of the analysis was a bevel gear characterised by an 18:43 gear ratio and arc tooth line, and manufactured according to the spiral generated modified-roll method.

Design/methodology/approach

The mathematical model of tooth contact analysis consists of both the mathematical model of tooth generating and the mathematical model of operating gear set. The first model is used to generate tooth flanks of the pinion and the ring gear in the form of grids of points. Then, such tooth surfaces are used for the tooth contact analysis performed with the other model. It corresponds to the no-load gear meshing condition. The finite element method model was built on the basis of the same tooth flanks obtained with the former model. The commercial finite element method software Abaqus was used to perform two instances of the contact analysis: a very light load, corresponding to the former no-load condition, and the operating load condition. The results obtained using the two models, in the form of the contact pattern for no-load condition, were compared. The effect of heavy load on contact pattern position, shape and size was shown and discussed.

Findings

The mathematical models correctly reproduce the shape, position and size of the contact pattern; thus, they can be reliably used to assess the quality of the bevel gear at the early stage of its design.

Practical implications

Determination of the correct geometry of the flank surfaces of the gear and pinion teeth through the observation of contact pattern is a fundamental step in designing of a new aircraft bevel gear.

Originality/value

A possibility of the independent use of the mathematical analysis of the contact pattern has been shown, which, thanks to the compatibility of the results, does not have to be verified experimentally.

Abstract

The cruise sector's workforce is highly diverse in terms of nationalities, age, and gender. However, diversity in the workforce does not guarantee business success.

Decades of research on the effects of diversity indicate that it can negatively or positively affect an organization's performance. A more diverse workforce does not automatically perform better financially, feels more committed to their companies, nor experiences higher levels of satisfaction. Indeed, data suggest diversity may produce more conflict, employee turnover, but if well managed can lead to greater creativity and innovation.

This chapter explores the cruise industry's diversity and inclusion challenges and management practices. To examine what cruise companies are doing in this field, we reviewed the public data of the four largest cruise companies. We analyzed how these companies define diversity, their commitment to inclusion, their practices, their metrics, and their primary objectives.

Firstly, there is no theoretical model that includes all variables that affect the management of diversity in the cruise sector. Secondly, companies communicate a commitment to inclusion in their corporate social responsibility (CSR) reports and refer to similar policies implemented by the hospitality industry. Thirdly, the main challenges are the multicultural environment and the limited female representation.

The major limitation of this study is the data source. We recommend further studies supported by nonpublic company data. We encourage cruise industry leaders to support the research to develop an empirically tested model that captures the specific variables that affect diversity management in the industry.
