The purpose of this paper is to focus on social representations of Warsaw (Poland) as a tourist destination of 210 first visitors from seven EU and extra-EU countries (France, Germany, Italy, Spain, Poland, United Kingdom and United States of America) interviewed before and after their visit. In the framework of the social representations theory, the “cultural baggage”, rooted in the collective and social memory, forms anticipatory representations of the imagined places that may undergo transformations after the visit. How does this transformation occur?

The authors consider the transformation of social representations as detected by means of a self-administered questionnaire that comprised the following tools: scales to measure the strength of various information sources about Warsaw (school, literature, movies, songs, internet, press, tourist guides, documentaries, interpersonal communication and other); associative networks (de Rosa, 2002) with the stimulus word “Warsaw”; a list of adjectives describing the city and its centre, as well as a list of the most important places in Warsaw. The questionnaires were coded to ensure anonymity of participants while enabling the researcher to administer them for the second time (after the visit). According to the modelling approach to social representations (de Rosa, 2013a), the research was guided by three related hypotheses concerning transformation of social representations of Warsaw.

The results confirmed the hypotheses of potential changes in the representations that shift the focus from Warsaw as “communist” to “green” capital city, and of the role of the Polish language as a “communicative barrier” for recalling specific names of city-places after their visit.

Social representations exist in people’s minds, and they include images that are further interpreted (Howarth, 2011). Especially when visitors are asked about places, it is likely that they recall specific images, but not their names. Since the questionnaires required them to write down the answers, words often did not correspond to the volatile and dynamic images that the human mind creates. In spite of recalling a specific park or fountain, participants resorted to general categories and simply wrote “park” or “fountain”. However, this limitation is familiar to the majority of social psychological researchers and very difficult, if not impossible, to overcome. The new research directions launched to integrate the research line of field studies with investigations based on new media offer complementary insights and opportunities (de Rosa and Bocci, 2014).

Destination branding has numerous practical implications. According to Ekinci and Hosany (2006), developing efficient communication methods is crucial to launching a distinctive and attractive destination personality. Hosany et al. (2006) have demonstrated that personality traits are ubiquitous in consumers’ evaluations of tourism destinations and therefore promotional campaigns should emphasize the distinctive personality of tourism destinations, based on the emotional components of destination image. European capital cities compete for visitors in the mature and saturated market, where brand strength is positively related to tourism intensity (Mikulić et al., 2016).

Examining how social representations of a city are transformed by the visit from the perspective of the supra-disciplinary theory of Moscovici constitutes an original way to link imagery and tourist practices. The major cultural issues, such as history, language, art and traditions affect the theory and practice of urban tourism. For the first time, this theoretical framework is being used in case of a post-communist European destination such as Warsaw.

In recent years worldwide interest has arisen in developing “child-friendly cities”, but research into this issue has so far not being carried out in Poland. Over the past decades one can observe a visible change which has taken place in the relationship between children and their living environment. In the many Polish cities (like in all industrialized countries) increased road traffic, pollution and crime, fragmentation of urban fabric, reduction of green public areas – resulted in rather ‘non child friendly’ environment. Although a child can play anywhere, carefully planned playgrounds are widely considered as an essential part of children's leisure and education. Today in Warsaw playgrounds could be found in a variety of settings as housing estates, recreation public areas, urban parks, schools, churches, community centres and commercial establishments as restaurants and hotels. But one can notice that demand for outdoor recreation shows signs of stopping, despite the efforts to supply much more sophisticated equipment. The aim of our research was to seek an answer for question how could we create an environment that meets a child's needs? Which factors determine child-friendly environment? In the course of our research project selected children's playgrounds in Warsaw were surveyed, undertaken on specific themes, such as: facilities, safety, pressures for change, popularity of sites, proposed strategy of renewal (with playground users interviewed). We were interested both in the children and their caregivers diversifying preferences, their expectations of outdoor recreation infrastructure and management improvements. As at present in Warsaw live as much as 5 528 disabled children therefore emphasis has been also placed on disabled children, their everyday access possibilities to public play space.

The aim of this paper was to verify applicability of graphene-based sensors for voltammetric and amperometric measurements of low-concentration compounds in biological fluids.

Using the screen printing method, electrochemical sensors were manufactured on polymethylmetacrylate foil using a paste consisting of organic solvents and graphene nanopetals. As the model of a biological fluid tear film was chosen, the compound chosen as the analyte was H₂O₂, which is produced in oxidation of biological compounds. Tear film analog was prepared, in which, the measurements were carried out in a wide range of concentrations to determine the oxidation potential of H₂O₂ through square-wave voltammetry. The second series of amperometric measurements was carried out for concentrations between 0 and 30 μM/L, which is the lower range of physiological glucose concentration in tear films.

The sensors presented linearity for concentrations from 0 to 3.5 per cent. Mean linear correlation coefficient between the peak current and the concentration for the examined sensors was 0.9764. Mean sensitivity was 434.4 mA·M−1·L−1.

Results indicate a need for optimization of the sensors ' performance. Main parameters to be improved are surface area of electrodes and purity of the graphene layer, as well as uniformity of the manufacturing process to improve accuracy and repeatability of measurements.

Technology and materials used present an opportunity for creating low-cost, miniaturized and biocompatible sensors to be used in medical monitoring.

Printed electronics technology described was not investigated previously in the field of biological sensors and could contribute to the solving of vital medicine problems.

The city as a form of spatial and social organization was in deep crisis for last years. Now in Poland we deal rather with the renaissance of urbanity. Increasing activity of social movements and the growing importance of civic participation are the most important evidence of this process. This chapter is about the role that public consultation on spatial planning can play in urban policy. The analysis is based on a case study of public consultations conducted with usage of active and innovative approaches. Authors describe the potential of such sociological intervention in solving the crisis of urban communities.

The purpose of this paper is to show the beginnings and development of digitization processes in University of Warsaw Library by examining the digital library of e‐bUW.

The main method is the comparison to other similar actions within the country of Poland. The subject scope of the paper also includes a description of methods of presenting digitized collections to patrons.

It turned out that fair visibility of catalogue records of digitized material is possible mainly because the Library of Warsaw University is a member of Digital Libraries Federation (Federacja Bibliotek Cyfrowych). Since 2007 the collection has been visited by over 5 million readers.

The original value of the paper is made by presenting efforts of one country on an international level to a broader audience with special attention to individual solutions.

This paper aims to examine the performance of corporate social responsibility (CSR) portfolio at the Warsaw Stock Exchange.

This paper uses the CSR portfolio of public companies that was selected in a three-step procedure. In total, 23 companies were selected and formed a CSR portfolio that is traded on the Warsaw Stock Exchange under the Respect Index. The Capital Asset Pricing Model (CAPM) is used to compare returns of CSR companies with respect to the market. The performance of this portfolio is measured in the period from 2010 to 2012.

This paper finds that the CSR portfolio measured under the Respect Index outperformed market in all time periods from 2010 to 2012. In addition, in 2010, the CSR portfolio exceptionally outperformed the market by almost 80 per cent. In 2011, even though the market was down, the CSR portfolio reported lesser losses: −0.93 vs −1.73 per cent. In the following year, the market regained and the CSR portfolio again outperformed the market by 14 per cent. This paper also finds that the CSR portfolio is more sensitive to systematic risk than to specific risk. In addition, the CSR securities move according to the market trend.

The limitation of this paper is attributed to a cause-and-effect relationship. In other words, it did not answer whether adopting CSR led to higher profitability or profitability reflected an awareness of market conditions that favored the adoption of CSR. The future research should focus on this issue and indicate whether investors prioritize CSR over profits or vice versa.

The results indicate that investments in CSR portfolio companies bring abnormal returns to investors. In addition, the CSR portfolio may resist market downturns and even bring exceptional profits to investors.

This study explains the CSR portfolio’s performance on the Warsaw Stock Exchange by using the CAPM.

International Business, Entrepreneurship.

This case has been used previously in an international business strategy module on MA courses at Kozminski University, Poland.

The case details Audioteka’s (a Polish audiobook company) history between 2007 and 2013, from the perspective of Marcin, one of the co-founders. The company was founded in 2008 by Marcin Beme and Blazej Kukla and internationalized soon after. Marcin was an experienced entrepreneur, while Blazej was a sound engineer. Both sought to combine their complementary skills and experience to start a business aimed at selling audio recordings. The case is divided into Parts (A) and (B) and is designed to teach international entrepreneurship, lying at the intersection of international business and entrepreneurship. Part (A) is set in 2011 and tracks the company’s evolution from the conception of an idea to establishing a start-up and developing a product. Part (B) is set in 2013 and covers early foreign expansion between 2011 and 2013. The case is focused on the challenges that Marcin faces when developing Audioteka and expanding abroad. It allows students to understand the decision-making logic of an international new venture (INV), choices made and execution while internationalizing. Students will be able to explore how a company adapts its product; how it enters foreign markets; how it overcomes the liabilities of foreignness, smallness, newness and outsidership through establishing partnerships with big companies (telecoms, automakers); and how it appreciates the risks involved in this process.

This case is the basis for a class discussion rather than for illustrating either effective or ineffective handling of a managerial situation. From this case, MA students will learn how an entrepreneurial firm makes strategic decisions and becomes international. The first learning outcome is to evaluate the concepts of liability of origin, foreignness, outsidership, smallness and newness, and to explore ways of overcoming them. Second, the expected learning outcome is to assess differences between the Uppsala model of internationalization and born-global/INV phenomenon. Third, students, by examining particular foreign market-entry modes, are expected to evaluate their advantages and disadvantages. Finally, students are expected to understand the concept of “effectuation” and apply it to the decision-making process in early internationalization.

CSS 5: International Business.

This study aims to measure the effect on prices through the differing characteristics and attributes of hotels.

A hedonic price model (HPM) was adopted to estimate the impact of various site and situational factors on hotel prices in Warsaw, Poland. To better understand room rates not explained by HPM, spatial analysis of residuals was used. Datasets regarding prices from three different online travel agents (OTAs) and star ratings, either official or provided by OTAs, were investigated.

A significant impact on hotel prices by star rating has been confirmed. Every additional star allows the hotel to set approximately 25 to 36 per cent higher prices, which is in line with previous studies. Moreover, two factors indicated a high but still underestimated theoretical hotel prices: location within the city centre and proximity to the international airport.

The results of this study suggest that hoteliers should use a spatial analysis of room rates offered by the competing enterprises. Moreover, managers are expected to verify their price tactics and policies according to the geographical determinants of hotel prices investigated.

The uniqueness of the study is highlighted by comparison of HPMs based on data from different OTAs, analysing differences in HPMs based on star ratings provided by OTAs and official systems and spatial analysis of residuals of estimated HPMs. Moreover, this study is among the first to examine the usage of HPM in the hospitality industry in East-Central Europe.

Machining fixtures must fit exactly the work piece to support it appropriately. Even slight change in the design of the work piece renders the costly fixture useless. Substitution of traditional fixtures by a programmable multi‐robot system supporting the work pieces requires a specific control system and a specific programming method enabling its quick reconfiguration. The purpose of this paper is to develop a novel approach to task planning (programming) of the reconfigurable fixture system.

The multi‐robot control system has been designed following a formal approach based on the definition of the system structure in terms of agents and transition function definition of their behaviour. Thus, a modular system resulted, enabling software parameterisation. This facilitated the introduction of changes brought about by testing different variants of the mechanical structure of the system. A novel approach to task planning (programming) of the reconfigurable fixture system has been developed. Its solution is based on constraint satisfaction problem approach. The planner takes into account physical, geometrical, and time‐related constraints.

Reconfigurable fixture programming is performed by supplying CAD definition of the work piece. Out of this data the positions of the robots and the locations of the supporting heads are automatically generated. This proved to be an effective programming method. The control system on the basis of the thus obtained plan effectively controls the behaviours of the supporting robots in both drilling and milling operations.

The shop‐floor experiments with the system showed that the work piece is held stiffly enough for both milling and drilling operations performed by the CNC machine. If the number of diverse work piece shapes is large, the reconfigurable fixture is a cost‐effective alternative to the necessary multitude of traditional fixtures. Moreover, the proposed design approach enables the control system to handle a variable number of controlled robots and accommodates possible changes to the hardware of the work piece supporting robots.

Today’s modern liquid propellant rocket engines have a very complicated structure. They cannot be arbitrarily downsized, ensuring efficient propellants’ mixing and combustion. Moreover, the thermodynamic cycle’s efficiency is relatively low. Utilizing detonation instead of deflagration could lead to a significant reduction of engine chamber dimensions and mass. Nowadays, laboratory research is conducted in the field of rotating detonation engine (RDE) testing worldwide. The aim of this paper is to cover the design of a flight demonstrator utilizing rocket RDE technology.

It presents the key project iterations made during the design of the gaseous oxygen and methane-propelled rocket. One of the main goals was to develop a rocket that could be fully recoverable. The recovery module uses a parachute assembly. The paper describes the rocket’s main subsystems. Moreover, vehicle visualizations are presented. Simple performance estimations are also shown.

This paper shows that the development of a small, open-structure, rocket RDE-powered vehicle is feasible.

Flight propulsion system experimentation is on-going. However, first tests were conducted with lower propellant feeding pressures than required for the first launch.

Importantly, the vehicle can be a test platform for a variety of technologies. The rocket’s possible further development, including educational use, is proposed.

Up-to-date, no information about any flying vehicles using RDE propulsion systems can be found. If successful in-flight experimentation was conducted, it would be a major milestone in the development of next-generation propulsion systems.
