A közlekedés földrajza

A közlekedés a társadalom és a gazdaság olyan szegmense, amely a pályák, a csomópontok rendszerén keresztül mozgatja az emberek, a termékek, a szolgáltatások és az információk tömegeit, miközben maga is a gazdálkodási rendszer működési mechanizmusának alávetettje. A közlekedés a tér szülötte, de működése közben éppen az őt létrehozó tér eltüntetésén fáradozik. A gazdaság ezen ér- és idegpálya rendszerének bemutatásával és működésének sajátosságaival foglalkozik ez a fejezet, melyet elsősorban a szolgáltatásokhoz kötődő szakoknak ajánlunk, de igen hasznos lehet a vidékfejlesztés és a turizmus iránt érdeklődőknek is.

Gazdaságföldrajzi tanulmányok közgazdászoknak

Az utóbbi évtizedekben a közgazdászképzésben háttérbe szorult a térbeli szemlélet jelentősége, pedig az információs társadalomban a gazdasági folyamatok már nem csak a fizikai térben, hanem a virtuális térben is tetten érhetők, régióról régióra változó életszínvonalat generálva. A tér digitális kiterjedése kölcsönhatásba kerül hagyományos fizikai környezetünkkel, ami még inkább amellett szól, hogy a közgazdász térszemlélet fontosságát e tanulmánykötettel kiemeljük. Tesszük ezt úgy, hogy a Corvinus Egyetem alapszakjainak hallgatóit szakonként szólítjuk meg egy-egy, számukra különösen releváns gazdaságföldrajzi témával. Ezáltal a többi magyarországi közgazdászképző intézmény szakjain tanuló hallgatók érdeklődését is felkelthetjük az új megközelítésű gazdasági térszemlélet iránt. Tartalomjegyzék: I.

Agency theory problems behind the fall of shopping centers

The present article assesses agency theory related problems contributing to the fall of shopping centers. The negative effects of the financial and economic downturn started in 2008 were accentuated in emerging markets like Romania. Several shopping centers were closed or sold through bankruptcy proceedings or forced execution. These failed shopping centers, 10 in number, were selected in order to assess agency theory problems contributing to the failure of shopping centers; as research method qualitative multiple cases-studies is used. Results suggest, that in all of the cases the risk adverse behavior of the External Investor- Principal, lead to risk sharing problems and subsequently to the fall of the shopping centers. In some of the cases Moral Hazard (lack of Developer-Agent’s know-how and experience) as well as Adverse Selection problems could be identified. The novelty of the topic for the shopping center industry and the empirical evidences confer a significant academic and practical value to the present article.

A közlekedés fenntarthatósága – közösségi közlekedés jövője

Közlekedésszakmai berkekben általános vélemény, hogy az egyéni közlekedés növekedési ütemének megállítása, vagy legalábbis mérséklése akkor valósítható meg, ha a közösségi közlekedés attraktivitása elér egy olyan szintet, amikor az egyéni közlekedéssel szemben megfelelő alternatívát nyújt. Minél többen veszik igénybe a közösségi közlekedést, annál inkább csökkennek a negatív környezeti hatások, így a zsúfoltság, a levegő szennyezése, a torlódás, a földterület felhasználása, a balesetek száma, a zajhatás. A közösségi közlekedés akkor lehet vonzó, ha az szabályozott verseny feltételei közepette működik, fenntartható és a mobilitás-menedzsment formálja a jövőjét.

A nagysebességű vasút térhódítása, és ennek hatása a turizmusszektorra

Míg a légi közlekedés teljesítménye meglehetősen hullámzó, a vasút napjainkban rohamos fejlődésnek indult. A Madrid–Barcelona útvonalon, mely nemrég még a világ legnagyobb légi forgalmával bírt, a nagysebességű vasút megjelenése drasztikus változásokat hozott. Az elemzés a vasút megjelenését követő időszak forgalmi adataira, illetve az árak, járatok és a szolgáltatási színvonal változásainak megfigyelésére támaszkodik. Bemutatja mind a verseny természetét, mind annak lehetséges, hosszú távú következményeit, az utazó érdekeit és a fenntarthatóság követelményét állítva középpontba.

Evaluating Effects of Everglades Restoration on American Crocodile Populations in South Florida Using a Spatially-Explicit, Stage-Based Population Model

The distribution and abundance of the American crocodile (Crocodylus acutus) in the Florida Everglades is dependent on the timing, amount, and location of freshwater flow. One of the goals of the Comprehensive Everglades Restoration Plan (CERP) is to restore historic freshwater flows to American crocodile habitat throughout the Everglades. To predict the impacts on the crocodile population from planned restoration activities, we created a stage-based spatially explicit crocodile population model that incorporated regional hydrology models and American crocodile research and monitoring data. Growth and survival were influenced by salinity, water depth, and density-dependent interactions. A stage-structured spatial model was used with discrete spatial convolution to direct crocodiles toward attractive sources where conditions were favorable. The model predicted that CERP would have both positive and negative impacts on American crocodile growth, survival, and distribution. Overall, crocodile populations across south Florida were predicted to decrease approximately 3 % with the implementation of CERP compared to future conditions without restoration, but local increases up to 30 % occurred in the Joe Bay area near Taylor Slough, and local decreases up to 30 % occurred in the vicinity of Buttonwood Canal due to changes in salinity and freshwater flows.

Mirror self-recognition in a gorilla (gorilla gorilla gorilla)

Psychologists have studied self-recognition in human infants as an indication of self-knowledge (Amsterdam, 1972) and the development of abstract thought processes. Gallup (1970) modified the mark test used in human infant work to examine if nonhuman primates showed similar evidence of mirror self-recognition. Chimpanzees (Pan troglodytes) and orangutans (Pongo pygmnaeus) pass the mirror self-recognition test with limited mirror training or exposure. Other species of primates, such as gorillas and monkeys, have not passed the mirror test, despite extensive mirror exposure and training (Gallup, 1979). This project examined a gorilla (G. gorilla gorilla) named Otto in the traditional mark test. Using the modified mark-test, there were more incidents of touching the marked area while Otto was in front of the mirror than when he was not in front of the mirror. These results indicated that Otto was able to show some evidence of selfawareness.

Metodologia de estimação de estados para tratamento de medições errôneas e registros não sincronizados em algoritmos de localização de faltas em linhas de transmissão

The performance of algorithms for fault location i n transmission lines is directly related to the accuracy of its input data. Thus, fa ctors such as errors in the line parameters, failures in synchronization of oscillographic recor ds and errors in measurements of voltage and current can significantly influence the accurac y of algorithms that use bad data to indicate the fault location. This work presents a new method ology for fault location in transmission lines based on the theory of state estimation in or der to determine the location of faults more accurately by considering realistic systematic erro rs that may be present in measurements of voltage and current. The methodology was implemente d in two stages: pre-fault and post- fault. In the first step, assuming non-synchronized data, the synchronization angle and positive sequence line parameters are estimated, an d in the second, the fault distance is estimated. Besides calculating the most likely faul t distance obtained from measurement errors, the variance associated with the distance f ound is also determined, using the errors theory. This is one of the main contributions of th is work, since, with the proposed algorithm, it is possible to determine a most likely zone of f ault incidence, with approximately 95,45% of confidence. Tests for evaluation and validation of the proposed algorithm were realized from actual records of faults and from simulations of fictitious transmission systems using ATP software. The obtained results are relevant to show that the proposed estimation approach works even adopting realistic variances, c ompatible with real equipments errors.

Myanmar MIL Workshop Series

The Mobile Information Literacy curriculum is a growing collection of training materials designed to build literacies for the millions of people worldwide coming online every month via a mobile phone. Most information information and digital literacy curricula were designed for a PC age, and public and private organizations around the world have used these curricula to help newcomers use computers and the internet effectively and safely. The better curricula address not only skills, but also concepts and attitudes. The central question for this project is: what are the relevant skills, concepts, and attitudes for people using mobiles, not PCs, to access the internet? As part of the Information Strategies for Societies in Transition project, we developed a six-module curriculum for mobile-first users. The project is situated in Myanmar, a country undergoing massive political, economic, and social changes, and where mobile penetration is expected to reach 80% by the end of 2015 from just 4% in 2014. Combined with the country’s history of media censorship, Myanmar presents unique challenges for addressing the needs of people who need the ability to find and evaluate the quality and credibility of information obtained online, understand how to create and share online information effectively, and participate safely and securely.
