In the current industrial context, the human workforce still represents a key resource thanks to its cognitive and motor flexibility. The present work explores the role of Industry 4.0 assistive technologies in production and logistics systems from a human-centric perspective. These technologies aim to provide cognitive or physical support to operators executing manual tasks, rather than substituting them. Therefore, there is need for a comprehensive understanding of the impact of assistive technologies on the well-being and performance of operators from a human-centric perspective. In this paper, a literature review on available assistive technologies is provided. Technologies are classified based on the type of manual task (picking, assembly), type of support provided to the operator (cognitive, motor), and potential drawbacks. Outcomes emphasize the need of a thorough human-centric perspective in developing and deploying assistive technologies.
BIM jest podstawą do zrealizowania idei cyfrowego bliźniaka, co z kolei przybliża branżę budowlaną do koncepcji gospodarki o obiegu zamkniętym. BIM łączy się z GIS, IoT, ML i wykorzystuje metody sztucznej inteligencji. Dotychczasowe badania wielokrotnie mapowały BIM w różnych kontekstach.

BIM is the basis for arriving at the idea of the digital twin, which in turn brings the construction industry closer to the concept of the circular economy. BIM enters into fusion with GIS, loT, ML and uses artificial intelligence methods. Research to date has repeatedly mapped BIM in different contexts. In systematic reviews, researchers have analyzed the current state of knowledge and/or techniques. An identified research gap is the lack of a systematic review that maps publications on the future of BIM. Hence, the aim of this thesis was to conduct a broad systematic review of available predictions of BIM development and directions for future BIM research. Artificial intelligence tools - dimension.ai and ChatGPT4 - were used to support this aim. The VosViewer tool was used in the mapping. The paper presents the current and future challenges facing the AECOO industry. A prediction was also made about the development of BIM in the coming years.

Purpose: to develop a proprietary typology of a business network based on a systematic literature review. Design/methodology/approach: the typology method facilitates the analysis and understanding of the essence of business networks by identifying and characterizing their different types. The systematic literature review (SLR) methodology was used to develop the typology, enriched with the snowball method. Findings: analysis of the content of publications selected during the SLR procedure made it possible to indicate various criteria for the division and types of business networks from widely quoted literature. On this basis, a typology of business networks was proposed, divided into four main types: networks originating from industrial districts, strategic networks, cooperation networks, and global business networks. Practical implications: the possibility of using the proposed concept in assessing various business network models will enable the formulation of diagnostic findings and comparative and dynamic research. Originality/value: at the current stage of scientific reflection, the developed typology enriches the theory of organizational networks by systematizing and comprehensively addressing business network models, which may lead to identifying trends in their development. It is addressed to both researchers dealing with network issues and practitioners.
Purpose: The purpose of this article is to identify the use of influencer marketing in place communication. Design/methodology/approach: For this purpose, a systematic literature review was conducted using Scopus and Web of Science databases. Findings: A total of 28 articles were identified. Finally, after rejecting duplicates and publications that did not meet the established criteria, the content of 9 articles was analysed. The main thematic threads and research methods were presented and leading journals and countries addressing the analysed issues were identified. Research limitations/implications: The analysis only considers publications in English, which has the effect of limiting the number of publications analysed. Practical implications: The results show a small number of publications dedicated to this topic. The phenomenon of influencer marketing is relatively new and some of the social media platforms have been established over the last few years. This makes it clear that, despite the great popularity of influencers as brand ambassadors or creators worth including in building marketing communications, the topic still needs to be analysed, both on a practical and research basis. Originality/value: This is the first literature review focused on the issues of place marketing and influencer marketing as activities that can have a mutually beneficial impact on promoted tourism destinations. The results of the conducted analysis may be of interest to both researchers of the analysed issue and practitioners, including in particular governmental and local governmental organisations responsible for the promotion of places.
Purpose: This study aims to map the development of research on ecological civilization with Chinese characteristics using the VOSviewer bibliometric analysis covering texts published until January 2023. The aim of the article is also to find elements of the economic sciences within the framework of the researched issues. Design/methodology/approach: The article includes a review of the most popular scientific bibliographic databases of scientific texts, namely Web of Science and Scopus, and a structured literature review of the texts. The bibliographic data has been processed in the VOSviewer program. Findings and Originality/value: Quantitative results were presented in the form of bibliometric maps, showing among others the relationship maps between watchwords and the existence of six clusters within WoS and five clusters within Scopus, as well as the presence of economic sciences in the studied area of ecological civilization and its Chinese characteristics. Social implications: The world’s environmental problems and the shared resolution regarding the implementation of seventeen Sustainable Development Goals Sustainable indicate the importance of the topic of sustainable development. China's economic development and its aspirations to become the world's leading civilization point to the need to consider the pursuit of sustainability and civilization together.
Purpose: Well-functioning banks are essential for the proper development of any economy. In addition, with the development of capital markets, capitalisation has been growing on local stock exchanges. However, the number of listed banks is still limited. These observations make it important to isolate the factors that shape market valuation of banks. This paper reviews the empirical literature on market valuation of banks and classifies the determinants of valuation. Design/methodology/approach: Review of the literature based on an analysis of 30 publications on the market valuation of banks. Findings: The factors that affect bank market valuation can be divided into a number of categories. The first category focuses on the connections between market value and financial aspects of banks. The relationship between the components of bank corporate governance and market valuation is discussed in the second group. We can distinguish between elements relating to boards, ownership structure, and other corporate governance elements in this group. The final section of the literature focuses on external variables that are unrelated to specific bank choices. Additionally, it is clear that Tobin's Q and MTB ratio serve as the two primary indicators of bank market valuation. Research limitations/implications: There are not many research looking at the factors that affect the market value of banks in emerging markets. A study of the market value of banks from these economies could be an important issue for future research. Practical implications: Knowing the elements that influence the market value of banks may be useful for investors considering investing in bank shares. Originality/value: This literature review focuses on isolating external and internal factors that the empirical literature has examined in the context of bank market valuation. This allows us to capture a potential research gap in this topic.
Simulator-based training has become an integral part of Maritime education, and its effectiveness hinges on the use of appropriate assessment protocols. Despite the existence of several subjective and objective assessment techniques, instructors face difficulties in selecting and implementing the best practices that fit different learning contexts. The contextualized utility of the available assessment techniques further complicates the contexts. This study adopts a systematic literature review approach to comprehensively analyse available assessment techniques employed in maritime simulator training and to elicit their relationship with the desired learning outcomes. The study also presents a nuanced understanding of the advantages and limitations of the identified assessment techniques. Further, the state-of-the-art of assessment methods is discussed along with a few proposals for the future considering both research and practical implications. The findings of this study are expected to provide valuable guidance to maritime instructors in selecting and implementing appropriate assessment techniques that align with desired learning outcomes in simulator training.
In 2018 during the 72nd session of the Maritime Environmental Protection Committee (MEPC) IMO adopted its initial strategy for the reduction of greenhouse gas emissions (GHG) from the ships to meet the Paris Agreement Goals, 2015. This is considered as a major milestone in formulizing a clear strategy by IMO towards its objective of reducing the global GHG emissions from the ships. The strategy had two primary objectives: the first was to decrease total annual GHG emissions by at least 50% by 2050 compared to 2008 levels. The second objective was to promote the phasing out of GHG emissions entirely. In 2020, the International Maritime Organization (IMO) conducted a study which revealed that greenhouse gas (GHG) emissions from shipping had increased by 9.6%. The rise in global maritime trade was identified as the main factor behind this increase. IMO's 2020 study also concluded that reducing GHG emissions by focusing only on energy-saving technologies and ship speed reduction would not be enough to meet the IMO's 2050 GHG reduction target. Therefore, greater attention needs to be given to the use of low-carbon alternative fuels. To understand the effectiveness of currently available technologies in reducing GHG emissions from ships, a literature survey was conducted in this study. The survey examined a range of related articles published between 2018 and 2022. This study aimed to identify the current stage and the quantity of literature available on various technologies and, more importantly, serve as a decision-making support tool for selecting a technology under specific circumstances in a quantitative manner. The technologies were divided into four groups: those that utilize fossil fuels, those that use renewable energy, those that use fuel cells, and those that use low-carbon or alternative fuels. The literature survey was conducted using Web of Science (WoS) and Google Scholar. The results of this study will also help to identify clear research gaps in comparing the effectiveness of various available technologies to reduce GHG emissions. Ultimately, the aim is to develop a comprehensive strategy that can be used to reduce GHG emissions from shipping and contribute to the global fight against climate change.
