Sähköinen huutokauppa ja dynaaminen hankintajärjestelmä

Opinnäytetyöni tavoitteena on esitellä olennaiset kohdat julkisten hankintojen sähköisessä menettelyssä. Arvioinnin kohteena on lokakuussa 2011 voimaan astunut laki sähköisestä huutokaupasta ja dynaamisesta hankintajärjestelmästä. Opinnäytetyöni on kirjoituspöytätutkimus, joka perustuu julkisia hankintoja koskevaan lainsäädäntöaineistoon sekä julkisia hankintoja tutkivien sidosryhmien tuottamaan kirjallisuuteen. Näkökulmana on sähköisen menettelyn sääntelyn tarkoituksenmukaisuus hankintayksiköiden sekä toimittajien näkökulmista. Sääntely julkisten hankintojen sähköisestä menettelystä tarkoittaa julkisilla varoilla hankittavien palvelujen sekä tavaroiden hankintaa sähköisessä verkkoympäristössä. Hankintayksikkö, kuten valtion tai kunnan viranomainen, voi tämän lain myötä suorittaa hankintaprosessin sähköisesti käyttöliittymän kautta haluamastaan tuotteesta tai palvelusta.

Assessing reading at Key Stage 2: SATs as measures of children's inferential abilities

This article describes two studies. The first study was designed to investigate the ways in which the statutory assessments of reading for 11-year-old children in England assess inferential abilities. The second study was designed to investigate the levels of performance achieved in these tests in 2001 and 2002 by 11-year-old children attending state-funded local authority schools in one London borough. In the first study, content and questions used in the reading papers for the Standard Assessment Tasks (SATs) in the years 2001 and 2002 were analysed to see what types of inference were being assessed. This analysis suggested that the complexity involved in inference making and the variety of inference types that are made during the reading process are not adequately sampled in the SATs. Similar inadequacies are evident in the ways in which the programmes of study for literacy recommended by central government deal with inference. In the second study, scripts of completed SATs reading papers for 2001 and 2002 were analysed to investigate the levels of inferential ability evident in scripts of children achieving different SATs levels. The analysis in this article suggests that children who only just achieve the 'target' Level 4 do so with minimal use of inference skills. They are particularly weak in making inferences that require the application of background knowledge. Thus, many children who achieve the reading level (Level 4) expected of 11-year-olds are entering secondary education with insecure inference-making skills that have not been recognised.

Municipalização da gestão ambiental: situação atual dos municípios do Estado do Pará

O objeto do presente trabalho incide apenas sobre a análise das estruturas de gestão ambiental no Estado do Pará. Cujo principal objetivo é analisar e avaliar a municipalização da gestão ambiental no Estado do Pará, sem levar em consideração o funcionamento real das estruturas ambientais no Estado. O município e as messoregiões foram escolhidos como forma de regionalização para verificação da efetividade da Política Estadual de Meio Ambiente e da municipalização da gestão ambiental. O Estado do Pará foi selecionado como área de estudo em virtude dos problemas ambientais e da preocupação do Estado em desenvolver políticas que combatam o passado descomprometido do Estado com o meio ambiente: incentivos fiscais e implantação de estruturas para projetos de desenvolvimento regional que impactaram o meio ambiente, e municípios de criação antiga e recente. Desta forma, quais as competências dos municípios no âmbito da legislação correspondente a gestão ambiental? Como está ocorrendo à descentralização da gestão ambiental no Estado do Pará? Quais as características atuais do meio ambiente? Para tanto, foi utilizado como metodologia: pesquisa bibliográfica e documental; e análise de dados dos municípios, através do IBGE (Instituto Brasileiro de Geografia e Estatística) e da SECTAM (Secretaria Executiva de Ciência, Tecnologia e Meio Ambiente). A importância do tema desenvolvido revela-se na necessidade de municipalizar a gestão ambiental, ou seja, na mudança de postura do estado, dantes centralizador e autoritário, para uma postura democrática, resultando na gestão ambiental e territorial, que consiste numa outra forma de elaborar, decidir e executar políticas públicas.

O lado escuro da capital social: implicações sociais e políticas

O artigo questiona a associação direta entre a interação em redes sociais e a produção de um tipo de capital social que traz ganhos benéficos à comunidade. O capital social pode adquirir formas e resultar em efeitos negativos sobre as relações sociais. Argumentase assim que relações fundadas em tais princípios, dependendo do tipo de vínculos entre os atores, do contexto sócio-econômico e da fragilidade das ações das instituições e do Estado, podem favorecer a emergência do lado escuro do capital social, conduzindo ao aumento do crime organizado, à perpetuação do clientelismo e da corrupção.

Optimización del peaje en autopistas interurbanas que compiten con carreteras convencionales libres de pago : una perspectiva de eficiencia y equidad

En algunos países, como por ejemplo España, es común que entre un origen y un destino existan dos carreteras paralelas en las que existen ciertas diferencias. La más importante es que una de las vías es una autopista que ofrece a los usuarios una mayor comodidad y un menor tiempo de viaje a cambio del pago de un peaje, el cual no es necesario abonar en la carretera convencional paralela. Así, el problema de la tarificación vial ha sido estudiado en diversas ocasiones. Existe un amplio consenso en que para lograr el máximo bienestar social, los usuarios deben internalizar las externalidades que producen y no perciben a través de un peaje. Sin embargo, dicho peaje puede perjudicar a los usuarios con bajos ingresos. Dependiendo del objetivo (por ejemplo, maximizar el bienestar, maximizar la equidad social, la amortización de la construcción de la carretera, etc) el peaje óptimo podría variar sustancialmente. La literatura académica acerca de los peajes, la eficiencia y la equidad es vasta y diversa. Sin embargo, hemos encontrado una deficiencia en dicha literatura sobre el peaje óptimo, en corredores donde una carretera y una autopista con diferentes características de calidad compiten para capturar el tráfico. Particularmente no se ha encontrado ninguna investigación acerca del establecimiento del peaje que maximice el bienestar social o la equidad para distintas distribuciones del valor del tiempo de viaje (VTT), caracterizadas por su media y varianza. Por ello, el principal objetivo de la investigación es estimar la influencia que tiene la distribución de la renta de una sociedad sobre el peaje óptimo. La presente tesis doctoral trata de obtener, por medio de una metodología robusta, las diferentes políticas de peajes que los planificadores de transporte deberían llevar a cabo según la riqueza y cohesión social de los potenciales usuarios del corredor, la demanda y el objetivo que se busque con dicha tarificación, esto es, maximizar el bienestar social o la equidad. Adicionalmente también se obtienen los peajes óptimos dependiendo de si el corredor se encuentra totalmente tarificado o únicamente se debe pagar un peaje por circular en la autopista. In some countries, such as Spain, it is very common that in the same corridor there are two roads with the same origin and destination but with some differences. The most important contrast is that one is a toll highway which offers a better quality than the parallel road in exchange of a price. The users decide if the price of the toll worth to pay for the advantages offered. The problem of road pricing has been largely studied. It is well acknowledged that in order to achieve the maximum social welfare, users must internalize the externalities they produce and do not perceive through a toll. However, that toll can harm users with low income. Depending on the objective (e.g. maximize welfare, maximize social equity, amortize the construction of the road, etc) the optimal toll might vary substantially. The academic literature about pricing, efficiency and equity is vast and diverse. However, as far as we have found, there is a gap in the literature regarding the optimal price where a road and a highway with different quality characteristics compete for capturing the traffic in a corridor. Particularly we did not find any research estimating the optimal welfare price or the optimal equity price for different Value of Travel Time (VTT) distributions characterized by different VTT average and variance. The objective of the research is to fill this gap. In this research a theoretical model in order to obtain the optimal price in a toll highway that competes for capturing the traffic with a conventional road is developed. This model is done from the welfare and equity perspective and for non‐usual users who decide over the expectation of free flow conditions. The model is finally applied to the variables we want to focus on: average value of travel time (VTT) which is strongly related with income, dispersion of this VTT, different kind of distributions of VTT and traffic levels, from free flow to congestion. Furthermore, we also obtain the optimal tolls with the corridor completely charged or with untolled alternative.

How varies optimal welfare pricing with income distribution? The case of the untolled alternative.

In some countries, such as Spain, it is very common that in the same corridor there are two roads with the same origin and destination but with some differences. The most important contrast is that one is a toll highway which offers a better quality than the parallel road in exchange of a price. The users decide if the price of the toll is worth to pay for the advantages offered. This problem is known as the untolled alternative and it has been largely studied in the academic literature, particularly related to economic efficiency and the optimal welfare toll. However, there is a gap in the literature academic regarding how it affects income distribution to the optimal toll. The main objective of the paper is to fill this gap. In this paper a theoretical model in order to obtain the optimal welfare price in a toll highway that competes for capturing the traffic with a conventional road is developed. This model is done for non-usual users who decide over the expectation of free flow conditions. This model is finally applied to the variables we want to focus on: average value of travel time (VTT) which is strongly related with income, dispersion of this VTT and traffic levels, from free flow to congestion. Derived from the results, we conclude that the higher the average VTT the higher the optimal price, the higher the dispersion of this VTT the lower the optimal price and finally, the more the traffic the higher the optimal toll.
