The paper is an attempt at reviewing the classical theory of externalities and club goods in the new context of flow economy and network relations, as well as the role of human capital connected with high quality surroundings (urban environment), which is a catalysing factor, and allows the formation of new resources and new competitive advantages for cities and busiensses.
The need for a dwelling is one of the basic needs of every human being. The housing policy, which belongs to one of the pillars of the social policy of the state, is responsible for satisfying this need. It is carried both at the central and local level. The report aims to show the evolution of this policy in Poland from 1989, when the burden of providing housing to the society was largely shifted to the private sector, to the present times, when the state is starting to take action to solve the problem of housing shortages for the less prosperous part of society. First, housing resources are characterized in terms of their ownership and function. Then, the housing policy, its objectives and instruments are described in theoretical terms. The competences of communes in the fi eld of housing economy are characterised in further part. The diagnosis of housing condition in Poland is presented in the regional context and compared to other countries. The last parts of the report deal with the assessment of housing policy in Poland after 1989 on the national and local level. Based on this assessment, recommendations have been made regarding the directions of activities at the local and supra-local level in the area of improving the condition of housing in Poland. Special emphasis in recommendations is placed on the need for an integrated approach to the implementation of housing policy.
In this paper we develop an open-economy endogenous growth model to examine the influence of fiscal policy on the economy in the long run. We allow for public deficit and 5 types of taxes. One of the novel features is separate treatment of interest rates on public and private debt, both of which are linear functions of appropriate debt-to-GDP ratios. Two extreme situations are analyzed: a model of “decentralized economy”, where economic agents do not take into account any externalities, and a model of “benevolent social planner”. We derive the rules of optimal fiscal policy that induce economic agents to internalize all externalities. Theoretical results are illustrated with an empirical analysis for Poland. The optimal values of several fiscal policy instruments for Poland are calculated.
Energy security is one of the most frequently analysed phenomena in the energy markets. Great variety of scientifc efforts should have indicated clear definition of the phenomenon. However, those studies highlighted more than 80 different definitions of what energy security really is. Due to the fact, that energy security is analyzed by different scientific disciplines, studies have provided a comperehensive reflection on the phenomenon.
The main objective of this paper is of the theoretical nature and focuses on showing energy security externalities. Author delivers an integrative review focusing on existing literature referring to the analyzed phenomena. Energy security is though studied only from the perspective of economics therefore interdisciplinary studies are out of the study scope. The reason for such scientific procedure stem from a belief that each discipline approach is different in terms of concepts, research methods and though results that are obtained. Therefore without undermining high value of interdisciplinary approaches to energy security, author decided to concentrate solely on economic perspective, which in energy security studies seems to be underestimated. Such approach in author’s belief helps achieve theoretical clarity of the below given analysis.
Presented paper is of the theoretical nature and focuses on showing energy security externalities. Critical literature review shows the literature mainstream in which energy security externalities are
W opracowaniu została przeprowadzona dyskusja na temat ekonomicznych efektów zewnętrznych, ze szczególnym naciskiem na efekty technologiczne. Zwrócono także uwagę na problem internalizacji ekonomicznych efektów zewnętrznych wywoływanych przemieszczaniem się (transportem) na obszarach dotkniętych procesem urban sprawl. Badania przeprowadzono dla wszystkich gmin krakowskiego obszaru metropolitalnego (KOM). W ich wyniku przedstawiona została wartość ponoszonych bezpośrednio strat finansowych oraz wartość straconego czasu generowana koniecznością dojazdów i powrotów w przestrzeni KOM-u.
Clusters belong to the regional innovation system, which led to the formulation and implementation of the cluster-based policy in many countries. The positive impact of clusters on the competitiveness of regions was confirmed by empirical studies. Absence of clusters means retardation in a regional development. The implementation of cluster policy supporting coopetition into the scope of principled regional policy assumptions seems urgent. In this way effective conditions for the formation of growth poles around industries specific for a given region will be developed and, consequently, the economic specialization of individual regions will be achieved. Observation of the benefits resulting from the functioning of clusters in the region, taking into account their possible negative impact, will allow to determine the specificity of regional development policy based on clusters. These problems indicated above are the subject of this study, based on the Polish and foreign literature available on the subject employing the desk research method.
The article presents a method for assessing emissions of harmful substances and noise from road and air transport, as well as a combined assessment of the emissions of these transport pollutants. The original analytical dependencies reflecting the emissions of harmful substances from road transport, developed as part of the EMITRANSYS project implemented at the Faculty of Transport of the Warsaw University of Technology, were taken into consideration, in which the unit values of the actual road emissions of harmful substances are a function of, among other things, route length or speed of the vehicles. However, the dependencies associated with noise emissions were taken from the applicable international guidelines for assessing environmental pollution by traffic noise.
The article also describes a case study in which the impact of Warsaw Chopin Airport on noise along the Warsaw road network and the entire Warsaw agglomeration was assessed. Analyses and discussions were carried out in the scope of the change in transport noise due to air operations carried out in the analysed area. As agreed, the combined impact of road and aircraft noise in the area under study is far more unfavourable than street noise alone. Thus, it can be seen that the assessment of noise levels carried out separately for individual modes of transport (in accordance with applicable regulations) should be supplemented with the assessment of traffic noise from all modes of transport – especially in the case of simulation tests of ecologically friendly changes in the area of transport.
The offshore Oil & Gas Industry is very important to the European Union economy. Therefore it must be properly monitored and protected, and legal regulations must be in place. Directive 2013/30/EU implemented on July 18, 2018 obliged EU Member States as well as operators and owners of oil and gas related activities in sea areas to implement solutions reducing the risk of major accidents, minor accidents and dangerous situations.
The purpose of the article is to identify all the possible hazards that may occur during oil and gas operations in marine areas and attempt to assess the risk along with providing effective responses in the event of its occurrence by preparing appropriate plans for responding to the situation. For the completion of the main purpose of the work the provisions of Directive 2013/30/EU of the European Parliament and of the Council of 12 June 2013 on safety of offshore oil and gas operations were presented and analyzed using the Hazard Identification method, the analysis of available reports prepared by the European Commission, classification bodies and own experience obtained while working in the offshore industry during searching, drilling and oil and gas production located under the seabed at the Polish Economic Executive Zone. The study presents numerous analyses and comments, which were presented in the form of graphs and tables, based on international reports and own experience gained while working in an offshore company.
This paper presents a robust control technique for small-scale unmanned helicopters to track predefined trajectories (velocities and heading) in the presence of bounded external disturbances. The controller design is based on the linearized state-space model of the helicopter. The multivariable dynamics of the helicopter is divided into two subsystems, longitudinallateral and heading-heave dynamics respectively. There is no strong coupling between these two subsystems and independent controllers are designed for each subsystem. The external disturbances and model mismatch in the longitudinal-lateral subsystem are present in all (matched and mismatched) channels. This model mismatch and external disturbances are estimated as lumped disturbances using extended disturbance observer and an extended disturbance observer based sliding mode controller is designed for it to counter the effect of these disturbances. In the case of heading-heave subsystem, external disturbances and model mismatch only occur in matched channels so a second order sliding mode controller is designed for it as it is insensitive to matched uncertainties. The control performance is successfully tested in Simulink.
Celem tekstu jest rozważenie niedostatecznie dotąd opracowanego problemu miejsca języka w myśli Karola Marksa. W pierwszej części artykułu omówionych zostaje kilka przykładów marksistowskich prób filozoficznej lub językoznawczej refleksji nad językiem. Stawiam tezę, że marksistowska teoria znaczenia nie rozwinęła się jako nurt współczesnej myśli ze względu na dominację „tradycyjnej teorii znaczenia” (TTZ) – abstrahującej od konkretnych społecznych uwarunkowań. W drugiej części wskazuję na dające się odnaleźć u Marksa zapowiedzi tendencji obecnych we współczesnej filozofii języka, takich jak eksternalizm czy pragmatyzm. Jednocześnie zaznaczam, że w kontekście materializmu historycznego nabierają one charakteru, który każe wyjść poza TTZ. Następnie argumentuję, że teoria języka z wykorzystaniem koncepcji podziału pracy językowej pozwala rozwiązać pewne trudności związane z Marksa koncepcją ideologii.
W tradycji sceptycznej samoświadomość była przezroczysta i pełniła funkcję bazy do wyrażania wątpliwości i rozwijania argumentów w ramach poszukiwania pewności. Po zwrocie językowym i zwrocie naturalistycznym filozofia współczesna rozwinęła argumenty przeciwko pewności i przeciwko priorytetowi epistemologicznemu danych samoświadomości (zarówno przedrefleksyjnej, jak i refleksyjnej). Refleksja raportuje strumień świadomości ex post, raporty są skromne i zależne od schematu pojęciowego podmiotu, natomiast dane przedrefleksyjne są mgliste. Współcześnie pojawiły się dwie sceptyczne hipotezy: H. Putnama hipoteza eksternalizmu treściowego i S. Kripkego hipoteza kwusa. Na ich tle można postawić pytanie, jakie ja jest odporne na błędną identyfikację. Odporność wydaje się ograniczona do ja beztreściowego jako przedpredykatywnego poczucia własnego istnienia. Nie ma gwarancji, że jakakolwiek treść przypisana własnemu ja jest bezbłędna. Nie mogę zaprzeczyć własnemu istnieniu, tak samo jak nie mogę zaprzeczyć temu, że coś zewnętrznego istnieje, ale każdy opis ich treści jest narażony na błędy. A zatem treści samoświadomości nie są w lepszej sytuacji epistemicznej niż treści percepcji zewnętrznej.
