This study reviews the teaching of real estate in the USA for the first 100 years after the foundational curriculum was laid down in 1923 by three key institutions: the National Association of Real Estate Boards (NAREB), the Institute for Research in Land Economics and Public Utilities (The Institute) and the American Assembly of Collegiate Schools of Business (AACSB). Its line of investigative pursuit is the persistent lamentation by American real estate scholars that real estate is not getting the respect it deserves as an academic discipline compared to its peers in the school of business such as accounting, finance and marketing. The study addresses a fundamental question: What is the cause of this endless “search for a discipline”? This is motivated by the belief that identification of the root cause of this “search for a discipline” will lead to the requisite solution: the intellectual foundation of the real estate discipline.

The study used qualitative document analysis to review two primary documents published in 1959 as reports on business education in the USA: (1) Higher Education for Business, financed and sponsored by the Ford Foundation, and (2) The Education of American Businessmen – financed and sponsored by the Carnegie Corporation of New York. The impacts of the publications on the teaching of real estate to date have been reviewed in the context of scholarly actions and literature that has been generated in relation to the two documents.

The two primary documents impacted negatively on the teaching of real estate. The committee members who produced the two reports had indicated that real estate did not fit into the business curriculum hence should not be taught in business school. This conclusion led to unintended negative outcomes for real estate education. The negative impact of the reports arose principally because the teachers of real estate misinterpreted the outcome to mean that they should tweak the real estate curriculum to fit in the pedagogical framework of the business school. This reaction is responsible for perpetuating the identity crisis that has plagued real estate as an academic discipline since its inception as a subject of study in 1923. Secondly, at the inception of the real estate education in 1923, while the AACSB accepted real estate as a discipline in the school of business, Richard T. Ely wrote the curriculum under land economics which has led to the persistent collegiate dilemma regarding the teaching of the discipline.

The study sheds light on the situation of business education in the USA and AACSB-accredited colleges internationally. It draws attention to the incoherent body of knowledge of business education and will help schools of business to redesign their curricula to include course contents that rightly reflects the business oriented academic disciplines.

The study is timely as it has been done 100 years since the development of the first standard collegiate real estate curriculum following the 1923 conference at Madison. The study has reviewed the first 100 years in terms of the persistent quest: “in search of a discipline”. In so doing, it has uncovered the root cause of this search during the first centennium; and to end the search, it proposes that real estate should not be taught as a business discipline.

This study aims to propose the reuse of PA12 (powder) in another AM process, binder jettiinng, which is less sensitive to the chemical and mechanical degradation of the powder after multiple cycles in the laser system.

The experimental process for evaluating the reuse of SLS powders in a subsequent binder jetting process consists of four phases: powder characterization, bonding analysis, mixture testing and mixture characteristics. Analyses were carried out using techniques such as Fourier Transform Infrared Spectroscopy, scanning electron microscopy, thermogravimetric analysis and stress–strain tests for tension and compression. The surface roughness, color, hardness and density of the new mixture were also determined to find physical characteristics. A Taguchi design L8 was used to search for a mixture with the best mechanical strength.

The results indicated that the integration of waste powder PA12 with calcium sulfate hemihydrate (CSH) generates appropriate particle distribution with rounded particles of PA12 that improve powder flowability. The micropores observed with less than 60 µm, facilitated binder and infiltrant penetration on 3D parts. The 60/40 (CSH-PA12) mixture with epoxy resin postprocessing was found to be the best-bonded mixture in mechanical testing, rugosity and hardness results. The new CSH-PA12 mixture resulted lighter and stronger than the CSH powder commonly used in binder jetting technology.

This study adds value to the polymer powder bed fusion process by using its waste in a circular process. The novel reuse of PA12 waste in an established process was achieved in an accessible and economical manner.

In a world that is more competitive on a global scale, technologically advanced and demanding than ever before, global situations such as climate change, poverty and inequality, health, migration or security are challenging for decision-makers in political, social or environmental contexts. The interplay of these and other tendencies is referred to as wicked problems, as their increasing complexity can often not be understood or distinguished anymore. Too many different crises, such as climate, economic, political or societal crises, are challenging the vulnerability and resilience of political, economic and community-based systems. Accordingly, focussing on battling single challenges without considering the bigger picture or interconnected processes or circumstances has not led to satisfactory results throughout the past decades. In a tourism industry that is traditionally closely interlinked with numerous sectors or stakeholder groups and therefore often associated with these problems, those in responsibility are particularly required to consider various interests and utilise the synergy potentials between the tourism and non-tourism sector. Accordingly, integrative tourism policy-making needs to include many political areas that are relevant within tourism as well as beyond, such as urban or regional development. As a holistic spatial development approach, the ‘ecosystem of hospitality’ (EoH) can facilitate the identification of interfaces between tourism and these political areas and help to foster a cross-stakeholder collaboration.

Compared with traditional methods relying on manual teaching or system modeling, data-driven learning methods, such as deep reinforcement learning and imitation learning, show more promising potential to cope with the challenges brought by increasingly complex tasks and environments, which have become the hot research topic in the field of robot skill learning. However, the contradiction between the difficulty of collecting robot–environment interaction data and the low data efficiency causes all these methods to face a serious data dilemma, which has become one of the key issues restricting their development. Therefore, this paper aims to comprehensively sort out and analyze the cause and solutions for the data dilemma in robot skill learning.

First, this review analyzes the causes of the data dilemma based on the classification and comparison of data-driven methods for robot skill learning; Then, the existing methods used to solve the data dilemma are introduced in detail. Finally, this review discusses the remaining open challenges and promising research topics for solving the data dilemma in the future.

This review shows that simulation–reality combination, state representation learning and knowledge sharing are crucial for overcoming the data dilemma of robot skill learning.

To the best of the authors’ knowledge, there are no surveys that systematically and comprehensively sort out and analyze the data dilemma in robot skill learning in the existing literature. It is hoped that this review can be helpful to better address the data dilemma in robot skill learning in the future.

Organisational learning (OL) is a critical capability family firms (FFs) need in order to adapt to an increasingly turbulent environment. Given the uniqueness of FFs and their differentiated decision-making processes, this review addresses fragmentation in the literature and synthesises prior research outlining the development of OL in FFs.

A systematic literature review was conducted using four databases, and 53 pertinent papers on OL in FFs published from 1998 to 2023 were analysed using the theory, characteristics, context and methodology (TCCM) framework.

The last five years (2019–2023) show a marked increase in interest in OL in FFs, with a rise in the number of quantitative studies. The findings indicate that OL is mainly studied as a unidimensional construct, while it is a multidimensional capability. Strategic management and organisational behaviour theories are commonly employed, while theories specific to family business such as socioemotional wealth (SEW) and familiness are underrepresented. Most studies focus on FFs in the Northern Hemisphere, and few studies examine OL in FFs located in the Global South. The TCCM framework reveals the complexity and multi-layered nature of OL in FFs.

This is one of the first systematic reviews to synthesise research on OL in FFs. The proposed research agenda identifies fruitful areas for future investigations concentrating on the multidimensional nature of OL, family-related outcomes, as well as contextual and methodological research directions of interest to family business researchers.

This study investigates the rise of online female entrepreneurship in emerging economies from institutional perspectives and the resource-based view (RBV). The research also explores how choosing online entrepreneurship affects the performance of female entrepreneurs.

Data were collected through surveys, and quantitative data analysis was used to test the hypotheses.

The results indicate that women entrepreneurs perceive online platforms as rare, valuable, imperfectly imitable and non-substitutable resources. Furthermore, the impact of informal institutions on choosing online platforms is supported, but the influence of formal institutions remains unclear. Additionally, the study finds that opting for online platforms helps entrepreneurs achieve financial and stakeholder relationship goals but does not significantly contribute to strategic and learning goals.

Our research highlights how transitioning from a physical to an online business platform can become a valuable resource for marginalized, deprived and struggling entrepreneurs, particularly women, operating within challenging institutional contexts, often prevalent in emerging economies.

The impact of digital technology in the wider travel field has been substantial and significant, changing both the competitive landscape of businesses and the behavior of travelers. However, we are now on the cusp of new digital developments encompassing cloud computing, blockchain, internet of things (IoT) and above all, artificial intelligence (AI), which are predicted to disrupt the business and consumer sides of several industries – travel included. This study aims to frame this upcoming digital transformation in travel within a human-centered approach where the critical understanding of digital humanism principles will enrich social scientists’ research agenda in the coming years.

The viewpoint follows a structure based on (i) setting the scene for the rise of digital transformation, (ii) the historical perspective on digital transformation in travel, (iii) the pandemic’s impact and (iv) future development and research agenda.

It is only by fostering a human-centered digital transformation perspective that social science researchers in travel can realize the “high-tech for high-touch” promise of fostering a human-to-human encounter empowered and possibly hampered, by digital technologies. This work proposes to start from the concepts of digital technology control, participation, education and ethics to design a research agenda with a 2050 horizon.

This work has been designed to shift the attention of researchers toward a human-centered digital transformation approach to reflect on the human-machine relationship for a better society. Due to its inner characteristics the travel field can foster a reflection on this topic by reaffirming the centrality of human beings and their authorship in the travel product creation.

This study aims to identify how Spanish consumers’ extrinsic preferences for food have evolved by examining the extant literature on food preferences in Spain, focusing on food-related attributes and food-related values.

This study is based on a synthetic review of the extant academic literature on Spanish consumer preferences for food-related attributes and food-related values from the mid-20th to the 21st century. This study uses key economic and social milestones that are most likely to influence food value chain actors to show how consumer preferences have evolved over the study period.

Spanish consumer food attribute preferences expanded as the food sector of the nation continued to grow, and value preferences showed a similar pattern from the mid-20th to the 21st century. The drivers of these preferences were trust, lifestyle, education (campaigns), sociodemographic factors and purchasing power.

Evaluating the extant literature’s contribution to consumer preferences for food-related attributes and values is important because it can aid in understanding the hierarchy and variety of consumers’ food preferences as well as the factors that drive these preferences. To the best of the authors’ knowledge, this study is the first to explore how Spanish consumer preferences evolved between the mid-20th and 21st centuries.

This paper explores the drivers and inhibitors of the transition of entrepreneurial family firms from small to large firms. We adopt two contrasting theoretical perspectives, i.e. agency and stewardship, to explore the effects of family power on size transition.

We adopted an original research design that leverages a unique longitudinal database built starting from the list of the 500 best Italian manufacturing family firms published by the AUB Monitor in 2018. Specifically, we tested our hypotheses using a comprehensive set of financial and governance data from 89 Italian manufacturing family firms covering a 10-year period. To test our hypotheses, we conducted a survival analysis using a Cox regression.

We find an inverted U-shaped relationship between family involvement in ownership and size transition: size transition is more likely to happen at intermediate levels of family involvement in ownership. Additionally, our analysis shows that family involvement in the board of directors negatively impacts size transition, while the presence of a family CEO has a positive influence.

To the best of our knowledge, this study represents the first exploration of the phenomenon of size transition within entrepreneurial family firms. We believe it was worthwhile for two reasons. First, small size is frequently regarded as a weakness when competing in international markets, investing in R&D, or rewarding shareholders. Second, since small family firms are the major contributors to the world economy, understanding the factors that facilitate their transition to large firms can have a significant impact on overall economic development and prosperity.
