This study aims to provide a comprehensive review of the existing literature on uncertainty in underground mining operations, using a bibliometric and systematic analysis covering the period from 1975 to 2024.

To achieve this, the following questions were addressed using a mixed-method approach involving bibliometrics, text mining and content analysis: How has the field of uncertainty research in underground mining operations evolved? What are the most prominent research topics and trends in uncertainty in underground mining operations? and What are the possible directions for future research on uncertainty in underground mining operations?

As a result, bibliometric networks of 327 journal articles from the Scopus database were created and examined, the main research topics were underground mining management; rock mechanics; operational optimization; and stochastic systems. Finally, the inclusive investigation of uncertainty in underground mining operations and its prominent patterns can serve as a basis for real-time direction for new research and as a tool to improve underground mining activities by implementing advanced technology for innovative practices and optimizing operational efficiency. This is fundamental to identify unknown variables that impair the planning, operation, safety and economic viability of underground mines.

This research is 100% original because there is no review research on the uncertainty present in underground mining operations.

In repetitive projects, repetition offers more possibilities for activity scheduling at the sub-activity level. However, existing resource-constrained repetitive scheduling problem (RCRSP) models assume that there is only one sequence in performing the sub-activities of each activity, resulting in an inefficient resource allocation. This paper proposes a novel repetitive scheduling model for solving RCRSP with soft logic.

In this paper, a constraint programming model is developed to solve the RCRSP using soft logic, aiming at the possible relationship between parallel execution, orderly execution or partial parallel and partial orderly execution of different sub activities of the same activity in repetitive projects. The proposed model integrated crew assignment strategies and allowed continuous or fragmented execution.

When solving RCRSP, it is necessary to take soft logic into account. If managers only consider the fixed logic between sub-activities, they are likely to develop a delayed schedule. The practicality and effectiveness of the model were verified by a housing project based on eight different scenarios. The results showed that the constraint programming model outperformed its equivalent mathematical model in terms of solving speed and solution quality.

Available studies assume a fixed logic between sub-activities of the same activity in repetitive projects. However, there is no fixed construction sequence between sub-activities for some projects, e.g. hotel renovation projects. Therefore, this paper considers the soft logic relationship between sub-activities and investigates how to make the objective optimal without violating the resource availability constraint.

This study aims to examine the impact of an organization’s digital transformation capability (DTC) on its dynamic capabilities and strategic depth, which, in turn, could impact the organization’s international market growth (IMG). This study also investigates the moderating role of leadership support (LES) in using the DTC.

The study reviews various kinds of literature related to international marketing, dynamic capabilities, digital transformation, strategic marketing and LES. Following this, a dynamic capability view is adopted to develop a research model. This research model is later tested using partial least squares structure equation modeling with data from 385 respondents from different types of organizations.

The study demonstrates that an organization’s DTC significantly enhances its dynamic capabilities and strategic depth. LES is vital for effectively applying and leveraging DTCs since it influences the association between DTCs, competitive advantage and global marketing intelligence. The study also recognizes that strategic depth and dynamic capabilities contribute to IMG.

The study uncovers the impacts of DTCs, influencing IMG. The study also provides valuable insights regarding the role of leadership in effectively leveraging the organization’s DTCs. It suggests the organization’s management should invest in improving DTC.

This study contributes to the prevailing literature on DTC, leadership and IMG. The study highlights the importance of DTC and how it impacts more established capabilities and leads to IMG of the organization. Further, this study is also unique as it establishes the importance of LES in leveraging the maximum benefits of the DTC.

This study aims to explore the relationship between foreignness and CEO pay.

This study combines cross-sectional and time series observations analyzed with panel data methodology in a sample of 59 firms listed in the Spanish IBEX-35 index between 2006 and 2020.

International ownership influences CEO underpayment and foreign sales influence CEO overpayment.

CEO pay is susceptible to being influenced by foreign non-American variables. An appropriate understanding of these factors can contribute to discussing policies that balance the level of CEO payment in large public firms.

Research on internationalization and CEO pay is scarce. A handful of studies confirm the link between Americanization and executive compensation in Europe. However, the authors still do not know if the level of CEO pay is influenced by non-American exposure. To do this, the authors test the effect of firm – ownership, sales, board – and individual – CEO – exposure to international, non-US environments on the level of over/underpayment of CEOs in a sample of Spanish firms.

Explorar la relación entre la extranjería y la remuneración de los CEO.

Combinamos observaciones transversales y de series temporales analizadas con metodología de datos de panel en una muestra de 59 empresas del índice IBEX-35 español entre 2006 y 2020.

La propiedad internacional influye en la remuneración insuficiente de los CEO y las ventas en el extranjero influyen en la remuneración excesiva de los CEO.

La investigación sobre la internacionalización y la remuneración de los CEO es escasa. Un puñado de estudios confirman el vínculo entre la americanización y la remuneración de los ejecutivos en Europa. Sin embargo, todavía no sabemos si el nivel de remuneración de los CEO está influenciado por la exposición no estadounidense. Para ello, probamos el efecto de la exposición de la empresa (propiedad, ventas, consejo) y del individuo (CEO) a entornos internacionales, no estadounidenses, sobre el nivel de sobre/insuficiente remuneración de los CEO en una muestra de empresas españolas.

La remuneración de los CEO es susceptible de verse influenciada por variables extranjeras no estadounidenses. Una comprensión adecuada de estos factores puede contribuir a discutir políticas que equilibren el nivel de remuneración de los CEO en las grandes empresas públicas.

Combinamos observações transversais e de séries temporais analisadas com metodologia de dados em painel em uma amostra de 59 empresas listadas no índice espanhol IBEX-35 entre 2006 e 2020.

A propriedade internacional influencia o sub pagamento de CEO e as vendas no exterior influenciam o super pagamento de CEO.

Pesquisas sobre internacionalização e remuneração de CEO são escassas. Alguns estudos confirmam a ligação entre americanização e remuneração de executivos na Europa. No entanto, ainda não sabemos se o nível de remuneração de CEO é influenciado pela exposição não americana. Para fazer isso, testamos o efeito da exposição da empresa - propriedade, vendas, conselho - e individual - CEO - a ambientes internacionais, não americanos, no nível de super/sub pagamento de CEOs em uma amostra de empresas espanholas.

A remuneração de CEO é suscetível a ser influenciada por variáveis estrangeiras não americanas. Uma compreensão adequada desses fatores pode contribuir para discutir políticas que equilibram o nível de remuneração de CEO em grandes empresas públicas.

Mass customization is a production process that allows consumers to customize products from an array of options to suit their preferences and needs and benefit from large-scale production efficiencies. In recent years, several apparel retailers have integrated customization into their online presence. While the benefits of online apparel mass customization (OAMC) are apparent, factors that determine the usage of the process are many. Therefore, it is important to explore these factors and understand the relationships between them and the impact on the intention to use OAMC.

A review of studies published in the last decade was conducted through the Scopus, Web of Science and JSTOR databases in September 2023. Peer-reviewed research articles published in the English language were included. These studies were carried out in the United States of America, Canada, Korea and China and addressed motivations and antecedents of OAMC technology.

The data were extracted, and the findings were synthesized. The review process enabled us to examine several theories and determinants of OAMC. The latter were categorized into the following themes: “consumer personality and psychology”, “consumer perceptions”, “consumer behaviour determinants” and “process, experience and product”. The influence of consumer personality traits, psychogenic needs, characteristics and other facilitating conditions emerged through the review.

The purpose of this paper is to study the various determinants of OAMC and thereby provide valuable information to businesses in OAMC domains to improve customized processes, understand consumers' motivations and develop marketing strategies that improve overall satisfaction with OAMC.

The development of high-strength engineered cementitious composite (ECC) gains a significant leap in structural engineering. Engineers have been looking for new formulations that combine outstanding compressive strength with increased flexural resistance. This research focuses on the main characteristics, techniques and prospective applications of high-strength ECC. The proposed work explores the composition of such concrete, emphasizing the use of novel additives, fiber reinforcements and optimal particle packing to produce excellent mechanical characteristics and demonstrating how high-strength ECC contributes to incorporate sustainability by potentially lowering the need for supplemental reinforcing and resulting in a lower environmental effect.

This research involves on studying the composition of high-strength ECC and geopolymer-based ECC, the use of novel additives, fiber reinforcements and optimal particle packing. It examines the capacity of high-strength ECC to sustain high loads with an allowable deformation without any catastrophic collapse. It discusses the sustainability aspects of high-strength ECC and its potential alternative as geopolymer-based ECC.

High-strength ECC offers an excellent compressive strength while also providing increased flexural capacity. Employment of copper slag (CS) as a filler material for the production of ECC results in 28.92% lower cost, when compared to the mix developed using conventional river sand. Whereas in the case of geopolymer-based ECC, the cost of production was found to be 31.92% lower than that of the conventional.

High-strength ECC is developed using conventional river sand and industrial by-product, CS as a filler material. The combination of achieving higher compressive strength with an increased use of industrial by-products leads to the development of sustainable high strength ECC. The potential use of high-strength ECC reduces the need for supplementary reinforcing and increases the structural lifetime, resulting in a lower environmental impact.

Going beyond the traditional approach of formal and informal institutions as antecedents of entrepreneurship (directly) and development (indirectly), this paper seeks to explore knowledge institutions as a necessary input for entrepreneurship and the development of societies.

Institutional economics lenses are utilized to observe other factors (e.g. the number of R&D staff and researchers from the public sector) that involve laws and socialization processes, which at the same time create knowledge useful for entrepreneurs and society. These ideas are tested through a sample of 281 observations from 17 autonomous communities and two autonomous cities in Spain. The information coming from the Global Entrepreneurship Monitor (GEM), Ministry of Economics, Industry, and Competitiveness, and INE (Instituto Nacional de Estadística), was analyzed through 3SLS, which is useful for a simultaneous equation strategy.

Knowledge institutions such as the number of R&D staff and researchers from the public sector are found positively associated with entrepreneurship, which is a factor directly and positively linked to economic development across Spanish regions.

The findings help the operationalization of other institutions considered in institutional economics theory and its application to entrepreneurship research. Moreover, the results bring new insights into the knowledge spillover theory of entrepreneurship in the public sector, in which the institutional analysis is implicit.

To answer the questions: what roles windows of opportunity act in the catchup process of latecomers, what strategies latecomer enterprises should adopt to size windows of opportunity to catch-up with incumbents even going beyond?

This paper studies the catch-up history of the Chinese mobile phone industry and proposes a sectoral innovation system under scenario of technology paradigm shifts. Then a history-friendly simulation model and counterfactual analysis are conducted to learn how different windows of opportunity and catch-up strategies influence the catch-up performance of latecomers.

Results show latecomers can catch up with technology ability by utilizing technology window and path-creating strategy. However, catching up with the market is not guaranteed. Demand window can help latecomers to catch up with market as it increases their survival rates, different sized windows benefit different strategies. However, it also enlarges incumbents' scale effect. Without technology window technology catch up is not guaranteed. Two windows have combination effects. Demand window affects the “degree” of change in survival rates, while the technology window affects the “speed” of change. Demand window provides security; technology window provides the possibility of a breakthrough for technology ability.

The findings of this paper provide theoretical guidance for latecomer enterprises to choose appropriate catch-up strategies to seize different opportunity windows.

This paper emphasizes the abrupt change of industrial innovation system caused by technology paradigm shifts, which makes up for the shortcomings of previous researches on industrial innovation system which either studied the influence of static factors or based on the influence of continuous changes.

The purpose of this study is to determine the moderating effect of group affiliation (GA) while examining the relationship of corporate governance (CG) with firm performance (FP) and firm risk-taking (FRT).

The study employed a sample of 100 non-financial firms, selected randomly from the top 500 companies listed on the Bombay Stock Exchange (BSE) based on their market capitalisation for 2013–2022. The random effects and fixed effect models are employed for the analysis. Furthermore, the generalised estimating equations (GEE) population-averaged model is used for added robustness.

The results reveal that while strong CG improves FP, GA modifies the effect of CG on FP. Both GA and CG have beneficial effects, but their synergy is insignificant. However, in the context of CG and FRT, the study unveils that a strong CG is associated with a reduction in FRT, and this relationship is more pronounced for standalone firms.

To the best of the authors' knowledge, the present study is a maiden attempt to investigate the moderating effect of GA while examining the relationship of CG with FP and FRT.

The purpose of this paper is to investigate the role of Customer Participation (CP) in the effectiveness of New Service Development (NSD) by examining the moderating roles of Customer Empowerment (CE) and Customer Satisfaction (CS). The research reduces the risk of failure of the NSD process and/or improves the NSD processes used by companies through the consideration of the results in the practical dimension.

This study investigates the effects of CP at different stages of NSD using a quantitative approach. Data were collected through an online survey questionnaire. Smart PLS was used to analyse the data collected from 509 newsreaders and users of the news agency’s application.

The model confirmed that CE has an impact on the effectiveness of NSD in the idea generation and commercialization stages, but not in the development stage. Empowerment and customer satisfaction did not influence the three stages of NSD indirectly but directly. The results show that CP, CS and CE do not always have a direct or indirect effect on the development of new services. Therefore, in order to design new service development projects, media news companies need to determine the level of user cooperation.

The lack of objective data, especially on company performance, forces researchers to use questionnaires to analyse NSD effectiveness. Another limitation is that newspaper users answered the questionnaires, which creates “common method variance.”

Researchers on NSD effectiveness must use questionnaires due to a lack of objective data, especially on company performance. Another limitation is “common method variance” from newspaper users answering questionnaires.

This paper is a response to a perceived need for an examination of how new service development can be successful and effective.
