The case study presented here discusses the story of Marek, who left his job in a corporation in Poland and set up his dream hotel business in Zanzibar. The first part of his story offers an excellent basis for discussing the role of distance in international business and learning the CAGE model. In the second part, the entrepreneur had to face up to the global pandemic, and decide whether to give up on his dreams or cope with the difficulties. Students working with this case thus have an opportunity to put themselves in the shoes of a transnational entrepreneur embedded in two countries, and to learn how a person’s perspective on distance might change in times of crisis.

The purpose of this paper is to present the methodology and approach adapted to conduct a wind tunnel experiment on the inverted joined-wing airplane flying model together with the results obtained.

General assumptions underlying the dual-use model design are presented in this paper. The model was supposed to be used for both wind tunnel tests and flight tests that significantly drive its size and internal structure. Wind tunnel tests results compared with the outcome of computational fluid dynamics (CFD) were used to assess airplane flying qualities before the maiden flight was performed.

Extensive data about the aerodynamic characteristics of the airplane were collected. Clean configurations in symmetric and asymmetric cases and also configurations with various control surface deflections were tested.

The data obtained experimentally made it possible to predict the performance and stability properties of the unconventional airplane and to draw conclusions on improvements in further designs of this configuration.

The airplane described in this paper differs from frequently analyzed joined-wing configurations, as it boasts a front lifting surface attached at the top of the fuselage, whereas the aft one is attached at the bottom. The testing technique involving the application of a dual-use model is also innovative.

The paper examines the commercial development of the Internet and WWW in Eastern Europe, with special attention given to such regional Internet leaders as Russia, Poland, the Czech Republic, Hungary, Estonia and Slovenia. Major commercial networks and Internet Service Providerrs are discussed and Web services offered by various companies are considered. The paper also looks into such commercial aspects of Web development as private business and legal information providers, Web advertising, and online shopping (mostly online bookstores, computer stores, and ‘shopping centers’). Finally, the question of the security of Internet transactions is considered as an important factor in the future growth of electronic commerce in Eastern Europe.

This paper aims to examine whether consumers’ appreciation of promotional gifts exceeds firms’ cost of providing these gifts. The paper also compares characteristics of appreciated and unappreciated gifts.

The authors surveyed 1,289 college students in five European countries. The authors use willingness to accept cash (WTA) for an item to assess consumers’ appreciation of promotional gifts. They then compare WTA to firms’ estimated cost of providing the gifts.

On average, consumers’ appreciation of promotional gifts is 2.4 times the estimated cost of these gifts to sellers. Appreciated gifts tend to be less costly, tend to accompany more expensive purchased items and are more likely to complement these items. The results also reveal that more expensive items come with more costly gifts, although the gifts’ cost increases less than proportionally with the associated items’ price. The gift items are appreciated by men more than women.

This study enriches the literature on promotional gifting by introducing a simple measurement that can help firms decide whether to use gifts or discounts to promote their products.

The purpose of this paper is to investigate the influence of metaliteracy on collaborative and individual information behaviour (IB) among academic staff. The goal is to observe the impact of these competencies on knowledge management (KM) and IB in research tasks connected with the humanities and social sciences.

This paper presents an implementation of two combined frameworks into a study on the IB of academics: metacompetencies described by Mackey and Jacobson in the metaliteracy model and Burke’s triple-A model. By using the Dervin’s micro-moment time-line interview framework, authors try to observe the state of development of information literacy and other supportive competencies among younger lecturers and researchers.

Scientists develop patterns of collaborative behaviour based on seven metaliteracy areas in KM.

The study did not include students and other groups related to the academic environment. Their involvement in information processes is a very wide issue and should be the subject of a separate article.

The paper contributes to research development in the area of information literacy as a KM efficiency factor. IB in this paper is a broad concept, in which the development of metaliteracy is an important aspect of lecturers’ and researchers’ KM and collaboration skills.

This paper aims to determine to what extent hotels and peer-to-peer (P2P) facilities are substitutes for travelers. It then examines whether hotels target business travelers and P2P facilities target leisure travelers.

The author collected characteristics of Shanghai hotels and P2P facilities from websites to determine on what basis the two accommodation types compete. The author then conducted a modified importance-performance analysis (IPA) to determine the relationship between accommodations' provision of these characteristics and their importance to Chinese business and leisure travelers.

The characteristics of hotels and P2P facilities systematically differ, and travelers perceive these differences as important. While the differences are significant across all price ranges, they are smaller for budget hotels than for high-end hotels. The modified IPA indicates that P2P facilities appeal more to leisure travelers than to business travelers. Yet hotels better satisfy the requirements of both types of travelers.

The findings imply that P2P facilities can target lower- and middle-income vacationing families by charging lower prices. High-end hotels can compete by providing more diverse services and greater value to business travelers and higher-income leisure travelers. Budget hotels can reduce costs by not providing non-essential characteristics.

This paper contributes to the discussion of the competition between hotels and P2P facilities by focusing on the Shanghai market. It uses the modified IPA to derive implications for lodging market segmentation.

The purpose of this study is to design and fabricate a simple passive sensor circuitry embedded into a printed circuit board (PCB) and then to examine its properties.

A passive sensor transponder integrated circuit (IC) working in the high frequency (HF) 13.56 MHz frequency band was selected for this study. A loop antenna was designed to make the reported sensor circuitry readable. Next, the sensor circuitry was fabricated and embedded into a PCB with the proposed technologies. Finally, properties of the embedded structures were examined as well-functional parameters of the sensor circuitries.

The described investigation results confirmed that the proposed technologies using an epoxy resin or standard materials used for PCB’s production allowed to successfully produce sensors embedded into PCBs. This technology did not have a negative significant impact either on quality of solder joints of the assembled transponder IC or on functional properties of the embedded sensor. Apart from the identification data, the reported sensor can provide information about a selected property of its environment, e.g. temperature when its internal temperature sensitive element is used or other factors with the use of external sensitive elements, such as humidity.

It is planned to carry on the reported investigations to examine other types of sensor circuitries capable of indicating e.g. humidity level and to evaluate influence of the proposed technology on their functional properties.

The reported sensor circuitries can be successfully used in electronic industry in internet of things systems not only to identify monitored electronic devices, but also to control selected parameters of external environment. This creates opportunity to detect device malfunction by detecting local temperature growth or to analyze its environment, which might allow to predict failure of controlled products using radio waves. This advantage seems to be extremely beneficial for applications, such as space, aviation or military, in which embedded sensor systems may lead to enhancing reliability of electronic devices by reacting on occurred failures in a more efficient way.

This study demonstrates valuable information for engineers conducting research on sensor components embedded into PCBs. The reported technologies are quite simple and cost-effective because of the use of standard materials known for PCB’s production or an epoxy resin which could be treated as an additional encapsulant material enhancing mechanical properties of the embedded sensor transponder IC.

The purpose of this study is to compare the spatial distribution of different types of Airbnb hosts – based on a novel typology – and to investigate their association with neighbourhood characteristics in Brussels.

This study describes the location of Airbnb dwellings across the types of hosts and use spatial tests to compare their distributions to the traditional hospitality industry. With regression models, this study examines the relationship between the provision of Airbnb listings and neighbourhood indicators.

While different types of hosts offer their listings in the same urban space, they also cover different areas and exhibit different clustering processes. Their locations are associated with structural, socio-economic and demographic neighbourhood characteristics that vary across the types and provide support for the new typology.

This study focuses on the type of Airbnb hosts and their listings in one year, 2019. It would be worthwhile to apply the typology to other cities and to observe how the distributions change over time, including the period of the COVID-19 pandemic.

To the best of the authors’ knowledge, this paper is the first to suggest a finer typology of Airbnb hosts than the regular distinction into professional and non-professional types and reveals how hosts differ in the location of their Airbnbs.

The purpose of this study is to give an in-depth understanding of the nature of business processes (BPs) from the perspective of their dynamism and knowledge intensity that will allow for their correct classification and provide practical and useful implications for their more relevant and effective management. A simple and low labor-intensive BP nature assessment approach is proposed that will allow for objective assessment and internal benchmarking of all BPs in a specific context of execution based on their nature.

The research is divided into two parts. The first comprises a systematic literature review (SLR) based on the resources of the ProQuest, Springer Nature and ScienceDirect full-text databases and the second includes illustrative case studies.

Building on the SLR, the authors identified and reviewed 3,385 articles and defined a set of criteria by which the nature of BPs can be assessed. Further, the authors proposed a BP nature assessment matrix together with complementary questionnaires for the evaluation of process dynamism and knowledge intensity. To demonstrate the logic of this approach, two illustrative case studies were presented.

The article contributes to the theoretical reflection on the nature of BPs in the knowledge economy. From the practical point of view, a novel approach to the assessment of the nature of BPs is offered. The approach is open and as experience is accumulated it will develop according to the data and recommendations collected.

The purpose of this paper is to verify results related to losses in the core of a brushless DC prototype motor, obtained using its computer FE models, by experimental tests on manufactured machines. The paper focuses on the comparison of losses in the core of a machine with a classical stator core made of an iron–silicon material (Fe–Si) and a new one made of a modern METGLAS material.

Computer models of the prototype motors were created using FEM. The designed machines were manufactured, and experimental tests were performed. To achieve high frequencies in rotating magnetic fields, motors with a stator to rotor pole ratio of 9/12 were built. Twin rotor approach was applied, as two identical rotors were built along the two geometrically identical stators made of different core materials.

Experimental studies have shown the superiority of the METGLAS material over the classical Fe–Si material. Material parameters were measured directly on the prepared cores as library data used in the simulation may be incorrect due to technological processes during core production, which was also verified. Problems related to twin rotor approach have been identified. Solution to the problem has been suggested. Necessity of 3D FEM modelling was identified.

The main source of originality is that METGLAS material used in the prototype machines was developed and manufactured by the authors themselves. Original approach to core parameter evaluation based on simplified methodology has been suggested. Another original part is a simplified methodology applied to loss measurement during no-load test.
