Privatization and PPPS in transportation infrastructure: Network effects of increasing user fees

PPPS: Problem: Public-private-partnerships in transport infrastructure characteristically increase user-fees. Purpose: We aim to identify the network effects of the use of PPPs and increased user tolls in road infrastructure. Methods: We study the increases in user tolls on motorways due to the use of PPPs in the US. Results and conclusions: Among other things, the monetization of motorways is associated with an increase in toll levels that has consequences for their users, and also for the rest of the sections of the network.

Letters from the War of Ecosystems – An Analysis of Independent Software Vendors in Mobile Application Marketplaces

The recent emergence of a new generation of mobile application marketplaces has changed the business in the mobile ecosystems. The marketplaces have gathered over a million applications by hundreds of thousands of application developers and publishers. Thus, software ecosystems—consisting of developers, consumers and the orchestrator—have emerged as a part of the mobile ecosystem. This dissertation addresses the new challenges faced by mobile application developers in the new ecosystems through empirical methods. By using the theories of two-sided markets and business ecosystems as the basis, the thesis assesses monetization and value creation in the market as well as the impact of electronic Word-of-Mouth (eWOM) and developer multihoming— i. e. contributing for more than one platform—in the ecosystems. The data for the study was collected with web crawling from the three biggest marketplaces: Apple App Store, Google Play and Windows Phone Store. The dissertation consists of six individual articles. The results of the studies show a gap in monetization among the studied applications, while a majority of applications are produced by small or micro-enterprises. The study finds only weak support for the impact of eWOM on the sales of an application in the studied ecosystem. Finally, the study reveals a clear difference in the multi-homing rates between the top application developers and the rest. This has, as discussed in the thesis, an impact on the future market analyses—it seems that the smart device market can sustain several parallel application marketplaces.

Revelações da crise: moeda fiduciária e as relações Tesouro/Banco Central

The current crisis shed a new light on issues that, previously, were not perceived as serious or important. It highlighted the close ties between fiat currency and government bonds denominated in it or, in other words, the relationship between Treasury and Central Bank. Two ill-conceived views of the "new consensus" on money that had turned into taboos were put in evidence. The first, derived from the quantitative theory, concerns the rejection of unsterilized monetary expansion; the second, directly related to the neoliberal ideology, prohibits or imposes strict limits on the role of central banks in the financing of public debts.

Development of internet-based value added services in housing estate business in Russia

Value added services are becoming increasingly popular as they increase the perceived value of the core product and can be a strong method of attracting customers and motivating them to make a choice. The purpose of this research is to develop internet-based value added services for housing estate business in Russia. The research is a case study of Russian housing estate market utilising a triangulation of methods for better results. For the qualitative data analysis, 7 interviews with heads of regional departments of construction companies from different regions of Russia were conducted. For the quantitative data analysis, a survey of 128 inhabitants of Saint-Petersburg housing estates was held. Factor analysis and descriptive statistics including cross-tabulations and chi-square tests for significance were used to analyse the results. In this study, a list 19 value added services that can be provided through online platforms in housing estate market was developed. These services fall into three big groups: social networking services, compulsory and additional services. Additionally, the question of monetisation of online platforms in housing estate market was discussed and three business models were suggested.

O trabalho e a gestão do cuidado em saúde: a construção de uma política nacional em saúde do trabalhador no Brasil: uma análise documental

O desenvolvimento dos modelos de produção acarretou diversas transformações na concepção da relação homem/trabalho. Com isso, o trabalho tornou-se um dos aspectos centrais na vida do homem moderno. Na relação com o trabalho, emergem diversos processos de subjetivação baseados nas práticas presentes nos contextos em que ele se realiza, bem como nos processos de saúde e doença. No Brasil, esse processo vem sendo delineado por questões políticas e sociais que levaram à emergência da chamada Política Nacional de Segurança e Saúde do Trabalhador, em 2004. Entretanto, esse tema e seus desdobramentos ainda são fortemente debatidos, uma vez que tal política não se encontra em intenso vigor, demonstrando um percurso em constante construção e ainda permeável à diferentes influências. Este trabalho busca problematizar as práticas que produzem processos de subjetivação do “sujeitotrabalhador” pautados em dispositivos biopolíticos, a partir da análise da gestão do cuidado em saúde do trabalhador no Brasil. Partindo dessa perspectiva, buscou-se analisar a construção das Políticas de Saúde do Trabalhador no país, focando a formulação da PNSST e sua perspectiva atual. Para isso, foram analisadas as estratégias de cuidado presentes nesta Política, bem como a forma como essas estratégias estão articuladas com a perspectiva da integralidade, uma vez que a integralidade é um novo olhar sobre a gestão do cuidado em saúde, criando novas possibilidades de um trabalho em saúde. Centra-se no fluxo do usuário, com mudanças na produção do cuidado em todos os níveis da rede pública de saúde. Primeiro, foram abordados os processos de construção e desenvolvimento da chamada “Saúde do Trabalhador” e, posteriormente, foi analisada a Política Nacional de Segurança e Saúde do Trabalhador – PNSST (2004) enquanto dispositivo de regulação das práticas de saúde, a partir do método genealógico de Michel Foucault, com foco na análise documental. O processo de construção da PNSST iniciou a partir da 1ª Conferência Nacional em Saúde do Trabalhador, o qual se delineou nas demais conferências realizadas de 2001 e 2005. Neste processo, podemos observar o conflito entre o trabalho como risco (trabalho-risco) e o trabalho como produção de subjetividade (trabalho-subjetividade), que levam a construção das noções entre saúdecontrole versus saúde-integralidade. A análise documental da PNSST de 2004 denota que ainda há uma prevalência do olhar da Saúde Ocupacional, pelo viés do trabalho-risco/saúdecontrole, uma vez que as estratégias de cuidado apresentam discursos de risco/agravo no trabalho, na patologização do sujeito e na monetarização da saúde. Além disso, de 2005 até meados de 2011, não houve a concretização e implantação da Política, sendo criados diferentes sentidos e, inclusive, convergindo as ações de Saúde do Trabalhador para o campo da Vigilância em Saúde, onde se encontra tal área no Ministério da Saúde hoje. Com isso, observamos que ao pensarmos na proposta de articular o campo da integralidade com a Saúde do Trabalhador, encontramos, na verdade, a construção de discursos pautados em estratégias biopolíticas de transformar a atividade laboral em risco que deve ser vigiado e medicalizado. Além disso, não há interface para absorção das demandas referentes à saúde do trabalhador no SUS. A criação de linhas de cuidado em Saúde do Trabalhador em Unidades Básicas de Saúde ou mesmo a criação de Unidade de Referência Especializada em Saúde do Trabalhador nos permite inserir este tema cada vez mais no campo da saúde pública no Brasil e diminuir a dispersão dos casos de sofrimento dos trabalhadores que ficam no nível do não dito.

Monetização dos riscos no meio ambiente do trabalho uma leitura a partir do liberalismo igualitário

Esta dissertação trata da Monetização dos Riscos no Meio Ambiente do Trabalho – fenômeno que autoriza a compensação financeira para o trabalhador em razão de sua exposição a riscos existentes no local de trabalho –, sob a ótica do Liberalismo Igualitário de John Rawls e Ronald Dworkin. O primeiro capítulo analisa e compara as teorias liberais igualitárias apresentadas por John Rawls e Ronald e Dworkin com a teoria da Análise Econômica do Direito de Richard Posner. O segundo capítulo demonstra quais são as práticas do ordenamento jurídico brasileiro com relação à monetização dos riscos. O terceiro capítulo realiza uma análise normativa e principiológica para responder se há necessidade de reformular tais práticas, analisando, ainda, quais são os óbices à efetivação da proteção aos trabalhadores.

On The Timing of Default Losses: When and Why?

At the light of what happened in 2010 and 2011, a lot of European countries founded themselves in a difficult position where all the credit rating agencies were downgrading debt states. Problem of solvency and guarantees on the states' bond were perceived as too risky for a Monetary Union as Europe is. Fear of a contagion from Greece as well was threatening the other countries as Italy, Spain, Portugal and Ireland; while Germany and France asked for a division between risky and riskless bond in order to feel more safe. Our paper gets inspiration by Roch and Uhlig (2011), it refers to the Argentinian case examined by Arellano (2008) and examine possible interventions as monetization or bailout as proposed by Cole and Kehoe (2000). We propose a model in which a state defaults and cannot repay a fraction of the old bond; but contrary to Roch and Uhlig that where considering a one-time cost of default we consider default as an accumulation of losses, perceived as unpaid fractions of the old debts. Our contributions to literature is that default immediately imply that economy faces a bad period and, accumulating losses, government will be worse-off. We studied a function for this accumulation of debt period by period, in order to get an idea of the magnitude of this waste of resources that economy will face when experiences a default. Our thesis is that bailouts just postpone the day of reckoning (Roch, Uhlig); so it's better to default before accumulate a lot of debts. What Europe need now is the introduction of new reforms in a controlled default where the Eurozone will be saved in its whole integrity and a state could fail with the future promise of a resurrection. As experience show us, governments are not interested into reducing debts since there are ECB interventions. That clearly create a distortion between countries in the same monetary union, giving to the states just an illusion about their future debtor position.

A proposal for a Business Framework targeted at emerging business services and applications

Un Service Business Framework consiste en una serie de componentes interrelacionados que permiten la gestión de servicios de negocio a través de su ciclo de vida, desde su creación, descubrimiento y comparación, hasta su monetización (incluyendo un posible reparto de beneficios). De esta manera, el denominado FIWARE Business Framework trata de permitir a los usuarios de la plataforma FIWARE mejorar sus productos con funcionalidades de búsqueda, describrimiento, comparación, monetización y reparto de beneficios. Para lograr este objetivo, el Business Framework de FIWARE proporciona la especificación abierta y las APIs de una serie de components (denominados \Generic Enablers" en terminología FIWARE), junto con una implementación de referencia de las mismas pueden ser facilmente integradas en los sitemas existentes para conseguir aplicaciones con valor a~nadido. Al comienzo de este trabajo de fin de master, el Business Framework de FIWARE no era lo suficientemente maduro como para cubrir los requisitos de sus usuarios, ya que ofrecía modelos demasiado generales y dejaba algunas funcionalidades clave para ser implementadas por los usuarios. Para solucionar estos problemas, el principal objectivo desarrollado en el contexto de este trabajo de fin de master ha consistido en mejorar y evolucionar el Business Framework de FIWARE para dar respuesta a las demandas de sus usuarios. Para alcanzar el pricipal objetivo propuesto, el Business Framework de FIWARE ha sido evaluado usando la información proporcionada por los usuarios de la plataforma, principalmente PyMEs y start-ups que usan este framework en sus soluciones, con el objetivo de obtener una lista de requisitos y de dise~nar a partir de éstos un roadmap de evolución a 6 meses. Después, los diferentes problemas identificados se han tratado uno por uno dando en cada caso una solución capaz de cubrir los requisitos de los usuarios. Finalmente, se han evaluado los resultados obtenidos en el proyecto integrando el Business Framework desarrollado con un sistema existente para la gestión de datos de consusmo energético, construyendo lo que se ha denominado Mercado de Datos de Consumo Energético. Esto además ha permitido demostrar la utilidad del framework propuesto para evolucionar una plataforma de datos abiertos bien conocida como es CKAN a un verdadero mercado de datos.---ABSTRACT---Service Business Frameworks consist on a number of interrelated components that support the management of business services across their whole lifecycle, from their creation, publication, discovery and comparison, to their monetization (possibly including revenue settlement and sharing). In this regard, the FIWARE Business Framework aims at allowing FIWARE users to enhance their solutions with search, discovery, comparison, monetization and revenue settlement and sharing features. To achieve this objective, the FIWARE Business Framework provides the open specification and APIs of a comprehensive set of components (called Generic Enablers in FIWARE terminology), along with a reference implementation of these APIs,, that can be easily integrated with existing systems in order to create value added applications. At the beginning of the current Master's Thesis, the FIWARE Business Framework was not mature enough to cover the requirements of the its users, since it provided too general models and leaved some key functionality to be implemented by those users. To deal with these issues, the main objective carried out in the context of this Master's Thesis have been enhancing and evolving the FIWARE Business Framework to accomplish with the demands of its users. For achieving the main objective of this Master's Thesis, the FWARE Business Framework has been evaluated using the feedback provided by FIWARE users, mainly SMEs and start-ups, actually using the framework in their solutions, in order to determine a list of requirements and to design a roadmap for the evolution and improvement of the existing framework in the next 6 months. Then, the diferent issues detected have been tackle one by one enhancing them, and trying to give a solution able to cover users requirements. Finally, the results of the project have been evaluated by integrating the evolved FIWARE Business Framework with an existing system in charge of the management of energy consumption data, building what has been called the Energy Consumption Data Market. This has also allowed demonstrating the usefulness of the proposed business framework to evolve CKAN, a renowned open data platform, into an actual, fully- edged data market.

Long-term drivers of broadband traffic in next-generation networks

This paper is concerned with long-term (20+ years) forecasting of broadband traffic in next-generation networks. Such long-term approach requires going beyond extrapolations of past traffic data while facing high uncertainty in predicting the future developments and facing the fact that, in 20 years, the current network technologies and architectures will be obsolete. Thus, "order of magnitude" upper bounds of upstream and downstream traffic are deemed to be good enough to facilitate such long-term forecasting. These bounds can be obtained by evaluating the limits of human sighting and assuming that these limits will be achieved by future services or, alternatively, by considering the contents transferred by bandwidth-demanding applications such as those using embedded interactive 3D video streaming. The traffic upper bounds are a good indication of the peak values and, subsequently, also of the future network capacity demands. Furthermore, the main drivers of traffic growth including multimedia as well as non-multimedia applications are identified. New disruptive applications and services are explored that can make good use of the large bandwidth provided by next-generation networks. The results can be used to identify monetization opportunities of future services and to map potential revenues for network operators. © 2014 The Author(s).

Ilmaispelien rahoitusmallit

Pelien tekeminen on yleensä huomattavan kallista. Näin ollen pelien suunnittelussa tulee ottaa huomioon myos niiden rahoitusmallit. Yleensä mitä enemmänn pelillä on pelaajia, sitä paremmin sillä myös ansaitaan. Tämä on tärkeä lähtökohta ilmaispelien rahoitusmalleille, joihin tämä työ keskittyy. Tämän työn aikana tullaan viittaamaan useisiin eri peleihin. Ilmaispeleissä retentio, eli tieto siitä siitä kuinka monet pelaajat palaavat takaisin seuraavana päivänä, on erittäin tärkeä. Tämä johtuu siitä että pelaajat käyttävät vaihte¬levan määrän rahaa peliin pitkällä aikavälillä. Siksi ydinpelin suunnittelussa pitää ottaa huomioon miten peli-istuntojen määrää voidaan kasvattaa vähintään päivittäiseksi, mutta mielellään useaan kertaan päivässä. Retention lisäksi ilmaispelien suunnittelussa on myos muita tärkeitä mittareita, kuten päivittäiset aktiiviset käyttäjät tai keskimääräinen tuotto per pelaaja. Näitä muitakin mittareita käsitellään tässä tutkielmassa. Ilmaispelimallissa rahoitusmekaniikat voidaan kohdistaa erilaisiin pelaajaryhmiin tai sitten luoda ne tarpeeksi yleispäteviksi kaikille. Mekaniikat voidaan kohdistaa myös pelin sisällä tiettyihin kohteisiin, kuten eri pelimuotoihin.
