The purpose of this research was to study the marketing of mobile applications. The main objective was to find out what are the most efficient ways of marketing to increase the sales for a mobile application within a highly competitive marketplace. The marketplaces, app stores, are studied from the perspective of size, ease of entry, competition and customers and their purchasing process. The study also includes research on what are some of the main marketing methods used in mobile app marketing in general. The study consists of two parts, theoretical and empirical research. Theoretical research was done by studying past scientific research on the chosen subjects. As the subject is very new, the research was also extended to other publications from the field of mobile technology. The empirical part was done through interviews and empirical experiments with a case-company, which were used to answer the main objective of this study. These experiments showed that the chosen methods of mobile app marketing, app store optimization, localization and selected social media marketing activities, created the most sales when used together. Positive results were seen also when the activities were conducted by themselves, but together they were able to push the case company to their all time best results. However the key to succeeding and hitting high positions in the app store rankings would most likely require creating a solid marketing strategy, trying out other marketing activities alongside the ones used here, without forgetting to stay on top of mobile technology trends.

This paper analyses reasons of the instability of the world monetary system. The author considers this problem from historical and contemporary perspectives. According to presented point of view banknotes and electronic money which replaced gold and silver coins in popular circulation are the most important reason of the instability. There are also proven positive and negative consequences of money instability. Reforms of the world monetary system need agreement within the global collective hegemony of state-powers and transnational corporations.

Production of a new system in any range is expanding dramatically and new ideas are there upon introduced, the logic stands behind the matter is the growth of application of the internet and granting web-based systems. Before producing a system and distribute to the customer, various aspects should be studied which multiple the profit of the system. The process of productizing a new system from being unprocessed idea until delivers to the final user has been unambiguous. In this thesis, the systematize service in a way that benefits both the customer and provider, along with an effort to establish trust and diminish customer’s risk and increase service productivity are in detail presented. Characteristics of Servitization and Productization as two faces of one coin have been interpreted. Apart from the abovementioned issues state of art, service-oriented architecture (SOA) and New Service Development (NSD) has been included in this report for solving the problem of gradually decline in value of companies.

In this article we study the effect of uncertainty on an entrepreneur who must choose the capacity of his business before knowing the demand for his product. The unit profit of operation is known with certainty but there is no flexibility in our one-period framework. We show how the introduction of global uncertainty reduces the investment of the risk neutral entrepreneur and, even more, that the risk averse one. We also show how marginal increases in risk reduce the optimal capacity of both the risk neutral and the risk averse entrepreneur, without any restriction on the concave utility function and with limited restrictions on the definition of a mean preserving spread. These general results are explained by the fact that the newsboy has a piecewise-linear, and concave, monetary payoff witha kink endogenously determined at the level of optimal capacity. Our results are compared with those in the two literatures on price uncertainty and demand uncertainty, and particularly, with the recent contributions of Eeckhoudt, Gollier and Schlesinger (1991, 1995).

Le facteur d'initiation de la traduction chez les eukaryotes eIF4E (4E) est un puissant oncogène en raison de sa capacité à faciliter l'export et/ou la traduction de certains transcripts, dont beaucoup sont eux-mêmes des oncogènes. 4E intéragit avec un grand nombre de protéines régulatrices dont la protéine 4E-T (pour 4E-Transporter). La capacité de 4E-T à modifier la localisation subcellulaire de 4E pourrait offrir un mécanisme permettant de modifier le potentiel oncogène d'une cellule. La surexpression de 4E-T dans des cellules d'ostéosarcome conduit à l’augmentation du nombre et de la taille des P-bodies, dans lesquels 4E colocalisent avec 4E-T mais pas avec la version tronquée 4E-T/Y30A. Cependant, les différentes expériences menées, permettant d’analyser les taux de transcription, la quantité de protéine, les profiles polysomiques ainsi que la distribution nucléo-cytoplasmique, montrent que la surexpression de 4E-T n'a pas d'effet sur la fonction de 4E. L'observation d’un enrichissement cytoplasmique et d’une charge réduite de ribosomes sur les transcripts codant les protéines cycline D1 et ODC (profile polysomique) dans la lignée 4E-T suggère un role de 4E-T dans la séquestration cytoplasmique de certains transcrips par un mécanisme qui reste encore à déterminer.

La présente étude conduit les traditions fragmentées de la culture littéraire de Trieste vers les préoccupations contemporaines de la littérature mondiale à l’époque actuelle où la mondialisation est largement perçue comme le paradigme historique prédominant de la modernité. Ce que j’appelle la « littérature globalisée » renvoie à la refonte de la Weltliteratur – envisagée par Goethe et traduite comme « world literature » ou la « littérature universelle » – par des discours sur la culture mondiale et le post-nationalisme. Cependant, lorsque les études littéraires posent les questions de la « littérature globalisée », elles sont confrontées à un problème : le passage de l’idée universelle inhérente au paradigme de Goethe entre le Scylla d’un internationalisme relativiste et occidental, et le Charybde d’un mondialisme atopique et déshumanisé. Les spécialistes de la littérature mondiale qui tendent vers la première position acquièrent un fondement institutionnel en travaillant avec l’hypothèse implicite selon laquelle les nations sont fondées sur les langues nationales, ce qui souscrit à la relation entre la littérature mondiale et les littératures nationales. L’universalité de cette hypothèse implicite est réfutée par l’écriture triestine. Dans cette étude, je soutiens que l’écriture triestine du début du XXe siècle agit comme un précurseur de la réflexion sur la culture littéraire globalisée du XXIe siècle. Elle dispose de sa propre économie de sens, de sorte qu’elle n’entre pas dans les nationalismes littéraires, mais elle ne tombe pas non plus dans le mondialisme atopique. Elle n’est pas catégoriquement opposée à la littérature nationale; mais elle ne permet pas aux traditions nationales de prendre racine. Les écrivains de Triestine exprimaient le désir d’un sentiment d’unité et d’appartenance, ainsi que celui d’une conscience critique qui dissout ce désir. Ils résistaient à l’idéalisation de ces particularismes et n’ont jamais réussi à réaliser la coalescence de ses écrits dans une tradition littéraire unifiée. Par conséquent, Trieste a souvent été considérée comme un non-lieu et sa littérature comme une anti-littérature. En contournant les impératifs territoriaux de la tradition nationale italienne – comme il est illustré par le cas de Italo Svevo – l’écriture triestine a été ultérieurement incluse dans les paramètres littéraires et culturels de la Mitteleuropa, où son expression a été imaginée comme un microcosme de la pluralité supranationale de l’ancien Empire des Habsbourg. Toutefois, le macrocosme projeté de Trieste n’est pas une image unifiée, comme le serait un globe; mais il est plutôt une nébuleuse planétaire – selon l’image de Svevo – où aucune idéalisation universalisante ne peut se réaliser. Cette étude interroge l’image de la ville comme un microcosme et comme un non-lieu, comme cela se rapporte au macrocosme des atopies de la mondialisation, afin de démontrer que l’écriture de Trieste est la littérature globalisée avant la lettre. La dialectique non résolue entre faire et défaire la langue littéraire et l’identité à travers l’écriture anime la culture littéraire de Trieste, et son dynamisme contribue aux débats sur la mondialisation et les questions de la culture en découlant. Cette étude de l’écriture triestine offre des perspectives critiques sur l’état des littératures canoniques dans un monde où les frontières disparaissent et les non-lieux se multiplient. L’image de la nébuleuse planétaire devient possiblement celle d’un archétype pour le monde globalisé d’aujourd’hui.

This paper considers the problem of language change. Linguists must explain not only how languages are learned but also how and why they have evolved along certain trajectories and not others. While the language learning problem has focused on the behavior of individuals and how they acquire a particular grammar from a class of grammars ${cal G}$, here we consider a population of such learners and investigate the emergent, global population characteristics of linguistic communities over several generations. We argue that language change follows logically from specific assumptions about grammatical theories and learning paradigms. In particular, we are able to transform parameterized theories and memoryless acquisition algorithms into grammatical dynamical systems, whose evolution depicts a population's evolving linguistic composition. We investigate the linguistic and computational consequences of this model, showing that the formalization allows one to ask questions about diachronic that one otherwise could not ask, such as the effect of varying initial conditions on the resulting diachronic trajectories. From a more programmatic perspective, we give an example of how the dynamical system model for language change can serve as a way to distinguish among alternative grammatical theories, introducing a formal diachronic adequacy criterion for linguistic theories.

This report outlines the problem of intelligent failure recovery in a problem-solver for electrical design. We want our problem solver to learn as much as it can from its mistakes. Thus we cast the engineering design process on terms of Problem Solving by Debugging Almost-Right Plans, a paradigm for automatic problem solving based on the belief that creation and removal of "bugs" is an unavoidable part of the process of solving a complex problem. The process of localization and removal of bugs called for by the PSBDARP theory requires an approach to engineering analysis in which every result has a justification which describes the exact set of assumptions it depends upon. We have developed a program based on Analysis by Propagation of Constraints which can explain the basis of its deductions. In addition to being useful to a PSBDARP designer, these justifications are used in Dependency-Directed Backtracking to limit the combinatorial search in the analysis routines. Although the research we will describe is explicitly about electrical circuits, we believe that similar principles and methods are employed by other kinds of engineers, including computer programmers.

Dar a conocer la problem??tica de la logopedia en el paral??tico cerebral, poco conocida en Espa??a, y observar las ventajas y desventajas de dos m??todos de reeducaci??n muy diferentes: el m??todo Bobath y el m??todo Tardieu, despu??s de experimentarlos. Reeducaci??n del habla y del lenguaje en el paral??tico cerebral. Realiza una descripci??n, basada en bibliograf??a y en la experiencia profesional en el campo, donde expone la problem??tica del habla y del lenguaje en el paral??tico cerebral y su reeducaci??n. Desarrolla ampliamente dos metodolog??as de reeducaci??n: Tardieu y Bobath y realiza un an??lisis comparativo de ellas, y una cr??tica, en diez aspectos relacionados con la alimentaci??n, el habla y el lenguaje. Bibliograf??a y experiencia profesional en el campo de la reeducaci??n. La par??lisis cerebral implica una lesi??n en el enc??falo. No es hereditaria e interfiere las capacidades motrices normales de donde se derivan los trastornos del habla y del lenguaje. La reeducaci??n de estos trastornos, junto al d??ficit mot??rico ha de realizarse de com??n acuerdo entre el fisioterapeuta y el logopeda. El m??todo Tardieu se basa en una rehabilitaci??n y reeducaci??n anal??tica a partir del estudio de diversos apartados y factores diferenciados entre s??, mientras que el Bobath se basa en una rehabilitaci??n y reeducaci??n global, a partir del estudio de niveles relacionados siempre entre s??. La ventaja de Bobath est?? en que tiene en cuenta la relaci??n entre el control motriz y la reeducaci??n del habla y del lenguaje, mientras que Tardieu tiene unos ejercicios pr??cticos que Bobath no considera.

El concepto de cultura engloba, no s??lo el conjunto de obras de creaci??n espiritual y art??stica, sino tambi??n el conjunto de los sistemas simb??licos, de las reglas sociales y de las destrezas que estructuran la vida colectiva de una sociedad estable en el tiempo. Las culturas son conductas aprendidas que se transmiten, social y simb??licamente, a trav??s del aprendizaje y de la educaci??n. Las lenguas adquieren un alto valor simb??lico, pues permiten el desarrollo y la transmisi??n de conocimientos, y son capaces de condicionar la visi??n del mundo y de la sociedad. La repetici??n de determinadas pr??cticas engendra una memoria cultural que se encarga de construir una identidad. Si estas pr??cticas se convierten en sociales a trav??s de un grupo de personas, se perfilan la identidad socio-cultural y la etnicidad de los pueblos: algunos obtienen la categor??a pol??tica de naciones, otros se mantienen de una importante identidad colectiva con proyecci??n hacia el futuro y se les denomina 'naciones-cultura'. La aparici??n de la globalizaci??n puede ocasionar la destrucci??n de identidades locales anteriores y la emergencia de nuevas identidades locales. La heterogeneidad cultural conlleva una problem??tica que las pol??ticas educativas deben enfrentar ofreciendo completar los procesos de socializaci??n desde la ??ptica de una sociedad participativa y democr??tica. La educaci??n puede ser un instrumento eficaz para promover y proteger las identidades culturales, as?? como para reducir algunos efectos negativos de la heterogeneidad cultural. Se debe tender a promover el di??logo entre identidades para lograr una integraci??n cultural democr??tica constituida desde la multiculturalidad, que asuma tanto la relatividad cultural como el universalismo.
