Opis:
Transnational corporations have been active in the world economy for hundreds of years – since the XVIth century – but new dimensions in their activities in the world economy have been observed since 1960. The activities of that type of companies are assessed differently. On one hand these companies create and have the access to technology, have huge technological and R&D capabilities, and marketing capabilities. They are also responsible for the creation of international trade and are the most important players on the market of FDI. However, on the other hand their market power sometimes is derived from their specific advantages which – on the selected markets – they are able to transform into political power without any accountability. They also use their specific advantages to generate market imperfections, remove competition and eliminate some conflicts, at the same time creating new ones, directly connected with their activities. In the article the author tries to assess the results of activities of these companies.

Opis:
The complex demand pattern of ride-sourcing remains to be a challenge to transportation modeling practitioners due to the infancy and the inherently dynamic nature of the ride-sourcing system. Spatial effects exploration and analysis protocols can provide informative insights on the underlying structure of demand and trip characteristics. Those protocols can be thought of as an opportunistic strategy to alleviate the complexity and help specifying the appropriate econometric models for the system. Spatial effects exploration is comparable to point pattern analysis, in which, signals from spatial entities, like census tracts, can be analyzed statistically to reveal whether a specific phenomenon respective signal distribution is a completely random process or if it follows some regular pattern. The results of such analysis help to explore the investigated phenomenon and conceptualize its causal forces. In this paper, we apply spatial pattern analysis edge methods integrated into a visual analytics framework to: (1) test the null hypothesis of system demand complete randomness; (2) further analyze and explain this demand in terms of the origin-destination (OD) flow and trips characteristics, i.e., length and duration; and (3) develop a pattern profile of the demand and trip characteristics to provide potential directions to modeling and predictive analytics approaches. This framework helps explain the ride-sourcing system demand and trip characteristics in space and time to fill the gap in integrating the system in multimodal transportation frameworks. We use the ride-sourcing trip dataset released from the City of Chicago, USA, for the year 2019 to showcase the proposed methods and their novelty in capturing such effects as well as explaining the underlying complexities in a streamlined workflow. The ride-sourcing demand hotspots were explored and identified in the city’s central business district. A novel method to capture and analyze the origin-destination flowlines was developed and implemented. Finally, a complementary trip characteristics pattern analysis was conducted to fully comprehend the system and validate the findings from the system demand points and OD-flowlines.

Opis:
niniejszym opracowaniu Autorka podjęła próbę ustalenia znaczenia korporacji transnarodowych w działalności badawczo-rozwojowej sfery biznesu w Polsce. Najistotniejsze analizy odnoszą się do struktury biznesowych B+R z podkreśleniem zaangażowania KTN w tworzenie wiedzy i technologii w Polsce, uwzględniając także dane sektorowe. Analizy pokazują niewielki postęp w biznesowych B+R w Polsce, który jednak opiera się głównie na filiach zagranicznych korporacji, podczas gdy rodzime firmy pozostają relatywnie bierne w tej materii.
In these article the Author aims to indentify the role of the R&D investments of the transnational corporations in Poland, starting from quantifying the deficit in the business expenditures on R&D. The most important analyses refer to the problem of the structure of BERD, particularly the engagement of TNCs in creating the knowledge and technology, also including data on sectors engagement. The analyses show a little progress in BERD structure, but these situation bases generally on the foreign multinationals R&D activity while the domestic enterprises are still relatively passive.
