Przestrzenne zmiany w strukturze produkcji rolnej w Unii Europejskiej
2016
Wiele zachodzących zjawisk, ich rozwój czy też kierunki zmian, uzależnione są od przestrzennych interakcji zachodzących pomiędzy sąsiadującymi regionami. Model przestrzennej analizy shift-share, który został wprowadzony do badań przez Nazarę i Hewingsa, przedstawia przestrzennie zmodyfikowane stopy wzrostu (tempa zmian) poszczególnych wariantów zjawiska przez uwzględnienie temp wzrostu zjawiska w obszarach sąsiadujących. Celem artykułu jest analiza zmian struktury towarowej produkcji rolnej w krajach Unii Europejskiej według wybranych rodzajów produktów rolnych z zastosowaniem przestrzennej metody przesunięć udziałów. W opracowaniu dokonano oceny tempa zmian wielkości zjawiska oraz zidentyf…
Specjalizacja i konkurencyjność krajów UE w zakresie produkcji zbóż
2018
W artykule przedstawiono wyniki badań dotyczących specjalizacji i konkurencyjności produkcji roślinnej w krajach Unii Europejskiej. Do badań wykorzystano metodę zmiany konkurencyjności Estebana-Marquillasa. Metoda ta pozwoliła wskazać wyspecjalizowane kraje icharakter zmian strukturalnych w zakresie produkcji upraw. Badania przeprowadzono na podstawie danych dotyczących wielkości produkcji roślinnej. Wszystkie dane zostały zaczerpnięte z baz danych Głównego Urzędu Statystycznego. Badanie obejmuje lata 2005-2016. Uzyskane wyniki pozwalają na wyodrębnienie (nierozłącznych) grup krajów specjalizujących się w produkcji poszczególnych gatunków zbóż. W zakresie produkcji pszenicy specjalizują się…
Connection between temperature, larval production, virulence and geographical distribution of Rhipidocotyle parasites infecting the duck mussel, Anod…
2015
In this thesis, two bucephalid trematode parasites Rhipidocotyle campanula and R. fennica, which use the same first (Anodonta anatina) and second intermediate (Rutilus rutilus) host were studied. The aim was to investigate the effect of temperature on one of the key processes in the transmission of these parasites: 1) the emergence of cercarial larvae from A. anatina over short (1 h) and 2) long (throughout the annual cercarial shedding period, from May to October) time periods as well, as on 3) mussel survival and 4) the seasonal timing of cercarial release. In addition, the aim was to study how the cercarial shedding traits are linked to the 5) geographical occurrence and abundance of the…
Upstream Product Market Regulations, ICT, R&D and Productivity
2013
Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus precisely try to estimate what are the specific impacts of these two channels and their shares in total impact as against alternative channels of investments in other forms of intangible capital such as improvements in skills, management and organization. For this, we specify an extended production function relating productivity explicitly to R&D and ICT capital as well as to upstream regulations, and two factor demand functions relating R&D a…
The production of “rhythms of responsibility” for childcare in a post-socialist society
2021
Drawing on 32 face-to-face interviews with mothers and childcare providers in Latvia, this paper examines the mundane mobilities. We argue that attention to mundane mobilities reveals crucial arran...
Defining Smart Cities: a relative and dynamic approach
2016
Although the level of interest in smart cities is growing, the main issue – the smart city concept – is still open. The definition of smart city is not shared as well as the way to measure city’s smartness. The main approach has developed the concept of an “ideal” city which every city should tend because it represents the optimal standard. In this context, the aim of our paper is to break with the traditional point of view in favour of a new concept of smartness which identifies a city specific value of smartness, based on the efficient use of its own resources and related to the different context in which a city is situated. Thus, in this way, the concept of smartness becomes relative. Mo…
On the emergence of the urban phenomenon. Part I
2001
In this paper we develop a relatively simple but general model describing the formation of urban agglomerations in a pre-industrial setting. Rural agglomeration on a local scale arises from the multiplication and specialization of intermediate goods and labor services, while dispersion is due to the commuting costs of agricultural workers. Urban agglomeration on a more global scale stems from the trade-off between increasing returns to scale and transport costs of goods. We derive a general equilibrium model of the formation of urban structures and show how population growth, strict indivisibilities and structural changes in the production sector can modify quantitatively and qualitatively …
Validare le pratiche collaborative per l’economia circolare urbana: il punto di vista del design.
2021
The article presents the results of the research activity carried out within the framework of the European project H2020 REFLOW, which aims to build an integrated approach for the development of innovative participatory practices dedicated to urban circular metabolisms. As a result of the survey conducted on the application of collaborative models for the urban circular economy, it emerged that there is no shared operational strategy that can be adopted for the circular development of complex systems, such as cities. Based on this premise, this paper offers a new perspective on how to build and validate a transitional pathway for the development of circular cities through the adoption of a …
Do Rent-Seeking and Interregional Transfers Contribute to Urban Primacy in Sub-Saharan Africa?
2006
We develop an economic geography model in which mobile skilled workers choose between working in the production sector or becoming part of an unproductive political elite. The elite sets tax rates on skilled and unskilled workers to maximize its own welfare by extracting rents, thereby influencing the spatial allocation of production and changing the available range of consumption goods. We show that such behavior increases the likelihood of agglomeration and of urban primacy. In equilibrium, the elite may tax the unskilled workers but will never tax the skilled workers, and there are rural-urban transfers towards the agglomeration. The size of the elite and the magnitude of the tax burden …
