State of the art of pricing policy in air transportation: network carriers vs. low-cost airlines

The modern air transport industry is highly competitive. To survive in the market, the implementation of a successful marketing strategy is fundamental. In particular, an effective pricing policy has become crucial for airlines to remain profitable. Correspondingly, the different types of airline in the market have also established very distinct pricing policies. The present study is based on a literature review and presents the state of the art of pricing policy in air transportation. The aim is to compare and discuss the pricing strategies of network carriers and low-cost airlines. Special attention is paid to Revenue Management, which is a very important management tool used by airlines to take advantage of the differences in willingness to pay of passengers. The pricing policy, however, depends on the overall business strategy of the airline. Results show many differences, resulting from the fact that these two types of airline are characterized by very different fundamental business models and, correspondingly, also target groups. Since network carriers and also low-cost airlines have adjusted their pricing strategies lately, these recent developments will be discussed as well. This paper adds to the knowledge of this topic because it presents the most up-to-date and complete study on pricing regarding network carriers vs. low-cost airlines.A moderna indústria do transporte aéreo é altamente competitiva. Para sobreviver no mercado, a implementação de uma estratégia de marketing bem-sucedida é fundamental. Em particular, uma política de preços eficaz tornou-se crucial para as companhias aéreas continuarem lucrativas. Os diferentes tipos de companhias aéreas no mercado também estabeleceram políticas de preços muito distintas. O presente estudo baseia-se numa revisão da literatura e apresenta o estado da arte da política de preços no transporte aéreo. O objetivo é comparar e discutir as estratégias de preços de companhias aéreas de linha e companhias aéreas de baixo custo. Atenção especial é dada à Gestão de Receitas (Revenue Management), que é uma ferramenta de gestão usada pelas companhias aéreas para aproveitar as diferenças na disposição de pagar dos passageiros. A política de preços, no entanto, depende da estratégia geral de negócios da companhia aérea. Os resultados mostram muitas diferenças, resultantes do facto de que esses dois tipos de companhias aéreas são caracterizados por modelos de negócios fundamentais muito diferentes e, correspondentemente, também grupos-alvo. Como as operadoras de rede e também as companhias aéreas de baixo custo ajustaram as suas estratégias de preços ultimamente, esses desenvolvimentos recentes também serão discutidos. Este documento contribui para o conhecimento deste tópico, pois apresenta o estudo mais atualizado e completo sobre preços de companhias aéreas de linha versus companhias aéreas de baixo custo.info:eu-repo/semantics/publishedVersio

Ce0.8Gd0.2O2‐δ / La0.6Sr0.4CoO3 Heterostructures prepared by pulsed laser deposition

Oxide interfaces have received greater attention due to the possibility to obtain properties that are very different from bulk materials. Due to the wide variety of electronic and ionic phenomena than can be detected at the interfaces, such materials have many technological applications [1]. Attention is being drawn to oxide heterostructures, a new family of artificial materials where electronic and ionic properties can be modulated at the interfaces by varying the characteristics of the layers [2, 3]. Slight variations in the near anionic-cationic order might take place if there exists strained interfaces. The interest in multilayared heterostructures derives from the mobility deffects and the space-charge-zone effects at the interfaces. In addition, a new degree of freedom related to the capacitive and resistive contributions is provided as a consequence of the size effects of these artificial structures. In the present work, for the first time, we investigate the structure, microstructure and electrical properties of a new family of heterostructured materials with alternated thin layers of La0.6Sr0.4CoO3 (LSC) and Ce0.8Gd0.2O2-δ (CGO) deposited by pulsed laser deposition on (110) NdGaO3 (NGO) single crystal substrates. In order to evaluate the interfacial contribution to ionic-electronic conductivity and know what is actually happens at the interface of MIECs, different heterostructures were prepared by varying both the number of bilayers (N) and the total thickness of the samples (N = 2 and 5; and the thickness were 50, 100 and 300 nm).Universidad de Málaga.

Does Corruption Have Social Roots? The Role of Culture and Social Capital

[Abstract:] The aim of this work is to analyse the influence of sociocultural factors on corruption levels. Taking as starting point Husted (J Int Bus Studies 30:339–359, 1999) and Graeff (In: Lambsdorff J, Taube M, Schramm M (eds) The new institutional economics of corruption. Routledge, London, 2005) proposals, we consider both the interrelation between cultural dimensions and the diverse expressions of social capital with corruption. According to our results, the universalistic trust (linking and bridging social capital) constitutes a positive social capital that is negatively linked to corruption. In contrast, the particularistic levels of trust (bonding) can constitute a negative social capital directly related to corruption levels. Furthermore, cultures which are favourable to the legitimation of dependency relations and the formation of closed particularistic groups (power-distance and community factors) create a breeding ground for the development of these amoral rent-seeking structures

Novel microstructural strategies to enhance the electrochemical performance of La0.8Sr0.2MnO3-δ cathodes

Solid oxide fuel cells (SOFCs) are one of the most efficient technologies for direct conversion of fuels to electricity. La0.8Sr0.2MnO3-δ (LSM) is the cathode material most widely used in SOFCs [1], however, LSM exhibits high activation energy for oxygen reduction reaction (ORR) and low ionic conductivity, which limits its application at reduced temperatures. In this material the electrochemically active reaction sites are restricted to the triple-phase boundary (TPB) near the electrolyte/electrode interface, where the electrolyte, air and electrode meet. Different strategies have been investigated to enlarge the TPB area of LSM, such as the production of nanocrystalline powders by precursor routes, preparation of composites by infiltration methods and thin films [2-4]. Here we present and compare innovative procedures to extend the TPB of LSM in contact with yttria-stabilized zirconia electrolyte: i) nanocrystalline LSM films deposited by spray-pyrolysis on polished YSZ electrolyte; ii) the addition of polymethyl methacrylate microspheres as pore formers during the spray-pyrolysis deposition to further increase the porosity of these films and (iii) the deposition of LSM by spray-pyrolysis on porous backbones of Zr0.84Y0.16O1.92 (YSZ), Ce0.9Gd0.1O1.95 (CGO) and Bi1.5Y0.5O3- (BYO) electrolytes previously fixed onto the YSZ electrolyte. The most remarkable peculiarity of this novel preparation method, compared to the traditional impregnation, is the formation of LSM thick film of 500 nm on the electrode surface (Fig. 1), which improves the electrical conductivity of the composite cathode. Thus, the optimization of this novel method would be an alternative to the classical infiltration with several advantages for the industry of planar SOFCs allowing the deposition of a wide variety of ceramic films over large areas with more uniform distribution of the catalyst, lower cost and only one deposition step is required to form the electrode. The morphology and electrochemical performance of the electrode have been investigated by scanning electron microscopy and impedance spectroscopy. Very low values of area specific resistance were obtained ranging from 1.4 cm2 for LSM deposited on polished YSZ to 0.06 cm2 for LSM deposited onto BYO backbone at a measured temperature of 650 ºC. This electrodes exhibit high performance even after annealing at 950 ºC making them interesting for applications at intermediate temperatures.Universidad de Málaga.

The Olson - Putnam Controversy: Some Empirical Evidence

[Abstract:] This paper explores the causal link between associationism and general trust. First we study the principal components that constitute social capital. Then we contrast a structural model identifying the relations between the relevant variables in the so-called Olson-Putnam aporia. The results of the empirical test on the determinants of social capital allow us to conclude that the extension of horizontal networks maintains a direct relation with this form of capital, but not those of vertical type

The Endowment of Social Capital as a Determinant of Corruption

[Resumen:] El objetivo del presente trabajo es abordar el papel que desempeñan los entramados sociales como factor explicativo de la corrupción. En particular, se trata de determinar en qué medida los niveles de corrupción percibidos a escala nacional están asociados a ciertas formas de confianza y normas sociales y, por lo tanto, a las dotaciones de las diversas expresiones de capital social. La evidencia empírica obtenida sugiere que la confianza generalizada y las normas universalitas constituyen un capital social positivo que está inversamente relacionado con los niveles de corrupción. Por el contrario, las variantes particularistas de la confianza representan un capital social negativo que está directamente vinculado a la generación de relaciones de corrupción.[Abstract:] The objective of the present work is to address the role played by social capital as an explanatory factor of corruption. In particular, we attempt to estimate to what extent the perceived levels of corruption are associated to certain forms of trust and social norms and, therefore, to social capital in its diverse expressions. The empirical evidence suggests that generalized trust and universalistic norms constitute a positive form of social capital that is inversely related to corruption. By contrast, the particularistic expressions of trust represent a negative social capital directly linked to the rising of corruption relationships

Effects of competition on religious markets: some empirical evidence

[Abstract:] The aim of this article is to assess, from an empirical point of view, the relative explanatory capacities of two hypotheses that address the link between economics and religion: the religious markets and the secularization hypothesis. First, we estimate a baseline model that takes into account both hypotheses jointly. Secondly, we study in a separate way the influence of socioeconomic development and market structure. Finally, we investigate the relationship between group size and religious commitment. Overall, the results suggest some supporting evidence for the predictions derived from the hypothesis of religious markets that emphasize the over-riding importance of the degree of competition as a determinant factor of religious behaviours
