Reports the results of a survey rating the amount and degree of the utilisation of printed materials in Polish academic libraries. The results which are presented by type (for example chemical, biological, technical libraries etc.) as well as by function (research libraries and libraries of educational institutions), concern the number of materials, including both books and periodicals. The authors include the amount of material in English as well as in other foreign languages. Figures illustrating the annual increase of these materials are also included. In addition, the article offers data which cover a number of issues, including the range of materials which were ordered at the request of users, the time of cataloguing, the number of loans, the number of unfilled orders, the extent of the utilisation of the collections, the number of interlibrary loans, as well as the relegation of outdated materials. Finally, the survey reveals information on the number of libraries which research into user needs, the number of libraries which are open on Saturdays and Sundays, and the number of libraries which provide special services such as weekend loans.

Crises are often studied in international business (IB) research as the external “context” for business strategies, but firms can also be active participants in the unfolding of crises. The study of crises in IB could benefit greatly from studying the role of multinational enterprises (MNEs) as active participants, rather than as mere passive actors, responding to exogenous events. History shows that IB crises typically unfold partially as exogenous processes, and partly as the result of MNE strategies. A multilevel and longitudinal approach to studying crises in IB is clearly necessary. This chapter considers the extent to which smaller events that preceded the present crisis – since 1989 – point to systemic problems in global governance. It also defines five overlapping lenses through which future IB studies can further create relevant insights on how to deal with crises: historic, macro, meso, micro and exogenous. The chapter finally serves as an introduction to the whole Progress in International Business Research volume by indicating the relevance of all parts and chapters that follow.

With the use of the grey incidence analysis (GIA), indicators such as the absolute degree of grey incidence (ε_ij), relative degree of grey incidence (r_ij) or synthetic degree of grey incidence (ρ_ij) are calculated. However, it seems that some assumptions made to calculate them are arguable, which may also have a material impact on the reliability of test results. In this paper, the authors analyse one of the indicators of the GIA, namely the relative degree of grey incidence. The aim of the article was to verify the hypothesis: in determining the relative degree of grey incidence, the method of standardisation of elements in a series significantly affects the test results.

To achieve the purpose of the article, the authors used the numerical simulation method and the logical analysis method (in order to draw conclusions from our tests).

It turned out that the applied method of standardising elements in series when calculating the relative degree of grey incidence significantly affects the test results. Moreover, the manner of standardisation used in the original method (which involves dividing all elements by the first element) is not the best. Much more reliable results are obtained by a standardisation that involves dividing all elements by their arithmetic mean.

Limitations of the conducted evaluation involve in particular the limited scope of inference. This is since the obtained results referred to only one of the indicators classified into the GIA.

In this article, the authors have evaluated the model of GIA in which the relative degree of grey incidence is determined. As a result of the research, the authors have proposed a recommendation regarding a change in the method of standardising variables, which will contribute to obtaining more reliable results in relational tests using the grey system theory.

This paper aims to tackle the problem of some ambiguity of the momentum equation formulation in the commonly used macroscopic models of two‐phase solid/liquid region, developing during alloy solidification. These different appearances of the momentum equation are compared and the issue is addressed of how the choice of the particular form affects velocity and temperature fields.

Attention is focused on the ensemble averaging method, which, owing to its stochastic nature, is a new promising tool for setting up the macroscopic transport equations in highly inhomogeneous multiphase micro‐ and macro‐structures, with morphology continuously changing in time when the solidification proceeds. The basic assumptions of the two other continuum models, i.e. based on the classical mixture theory and on the volume‐averaging technique, are also unveiled. These three different forms of the momentum equation are then compared analytically and their impact on calculated velocity and temperature distribution in the mushy zone is studied for the selected test problem of binary alloy solidification driven by diffusion and thermal natural convection in a square mould.

It is found that a chosen appearance of the momentum equation mildly affects temporal velocity/temperature, and shapes of the phase interface at longer times of the solidification.

This mainly results from small variations of the liquid fraction across the mushy zone and from a low solidification rate, and it may change drastically when anisotropic properties of the mushy zone, solutal convection, different phase densities and cooling conditions are considered. Therefore, further comprehensive study is needed.

The paper addresses how the different focus of the momentum equation for liquid flow is compared.

The purpose of this paper is to evaluate the conditions in which a saturation of the common mode (CM) choke might appear to be essential for proper design of the CM voltage filters. This paper presents a method for the determination of a CM choke flux density produced by multilevel inverters with carrier‐based modulations.

The proposed combination of secant and tangent methods allows efficient and high‐resolution determination of the CM voltage waveforms produced at the output of the multilevel inverters with commonly used carrier‐based modulations.

The presented results show that the application of a five‐level inverter with specific modulation causes a decrease of the maximum flux density, down to 15 per cent of the maximum level of the flux density reached in a two‐level inverter. The proposed, dedicated approximation method provides an accuracy of the root estimation better by about three orders for a comparable number of the function calls in comparison with Brent's method.

The presented theoretical evaluations make possible the determination of the maximum expected value of the flux density produced by multilevel inverters with various types of carrier‐based modulations, which allows a reduction in dimensions, weight and cost of CM chokes applied in CM voltage compensators.

In the paper, the new formulas that describe the placement of triangular carrier functions for commonly used multilevel inverters have been presented. In order to avoid accumulation of the estimation error, during determination of the CM voltage time integral, a dedicated, efficient method of roots approximation has been developed.

This chapter attempts to assess the impact that the current Covid-19 pandemic can exert on the globalization process. The pandemic crisis, which fully unfolded worldwide in March 2020, had dramatic consequences for the world population, some of which are of economic character. As some of the global value chains and international trade and investment relationships were destabilized or suspended, a legitimate question arises as to the possible progress of the globalization process. The authors commence with a multidimensional concept of globalization and its critical evaluation. Subsequently, three possible scenarios of pandemic-induced development are identified and explored: disrupted globalization, de-globalization, and finally rebalanced globalization. The discussion of these scenarios also includes implications for economic policy.

The purpose of this paper is to examine how exposure to a cause-related marketing (CRM) initiative involving sport teams affects attitude formation for the team and its amplification of purchase intention for team-branded merchandise. Specifically, this paper assessed the role of distinct measures (warmth, brand attitude, admiration and success) on purchase intention.

The hypothesized model was tested using a 2 (promotion: CRM vs non-CRM) × 2 (team: successful vs unsuccessful) between-subjects design. Following MANCOVA analysis, the moderating effect of success was explored within the sequential moderated mediation model where perceived warmth and brand attitude explicated the effect of CRM exposure on purchase intention.

The results of this paper suggest that a “Warmth Effect” played a prominent role in shaping consumer perception for sports teams when partnered with a non-profit brand in a CRM appeal. Perceived team success was revealed as moderator, while warmth, brand attitude served as serial mediators on purchase intention.

This paper provides evidence-based insights to sport marketers to leverage CRM strategy in strengthening brand-related outcomes. Sport marketers may find the CRM strategy useful for engaging “casual” fans. Further analysis is needed to determine the generalizability of this consumer response to CRM in other product domains.

Practical implications include leveraging CRM strategy to strengthen brand-related outcomes (i.e. perceived warmth, brand attitude and purchase intention), while also being mindful of the timing of CRM initiatives to optimize engagement. Sport marketers may find the CRM strategy useful for engaging “casual” fans.

This paper lends clarity to brand attitude formation in the context of CRM. The findings of this paper demonstrate the influence of perceived warmth, brand attitude and success on purchase intention.
