I ara què? que hi ha en polítiques de joventut després del Plans de Joventut?

Fa més de 10 anys del primer Pla Nacional de Joventut de Catalunya, del pas de les polítiques de suport a l’associacionisme a les polítiques integrals, i amb aquestes la prolífica etapa dels Plans de Joventut i de l’expansió real de les polítiques de joventut al territori català. És a dia d’avui, en un moment de grans esdeveniments en aquest camp, en que es proposa un anàlisi sobre la futura evolució de les polítiques de joventut, basat en l’estudi i la interpretació de la informació existent i les aportacions de 9 persones vinculades al món de les polítiques de joventut

La ejecución de las sentencias urbanísticas

El Estado español tiene más de 100.000 construcciones ilegales. En la actualidad, la ejecución de las sentencias en materia urbanística no es eficaz. Existe, por tanto, una situación de inejecución de las sentencias urbanísticas. Un ciudadano puede construir una casa al amparo de una licencia. Sin embargo, a veces, esta licencia es ilegal porque infringe el plan urbanístico aplicable y incluso la propia ley de urbanismo. La consecuencia jurídica de la ilegal es la obligatoriedad del derribo de lo ilegalmente construido. Lo mismo sucede ante la declaración de ilegalidad de un plan urbanístico. En este caso, el juez o tribunal estimará la ilegalidad del plan y el fallo deberá ser ejecutado. La solución no es un fácil porque la demolición o derribo de la construcción ilegal trae consigo el pago de una indemnización a los propietarios que han edificado al amparo de una licencia ilegal.El derecho a la ejecución de sentencias es prescrito por el artículo 24 de la Constitución española. Este artículo 24 garantiza el derecho de todos ciudadanos a una tutela judicial efectiva. El Tribunal Constitucional español en sus sentencias número 67/1984 y 28/1989, reconocieron que el derecho a la ejecución de las resoluciones judiciales deriva del propio derecho a la tutela judicial efectiva. La justicia administrativa está regulada por la Ley 29/1998, del 13 de julio, reguladora de la jurisdicción contencioso-administrativa. En su artículo 103.1 de la Ley 29/1998, establece que los jueces y los tribunales de la jurisdicción administrativa son los competentes para hacer ejecutar las sentencias. Por otro lado, el artículo 117.3 de la Constitución Española otorga la competencia en exclusiva a los jueces y tribunales para hacer ejecutar las sentencias, como manifestación del principio de división de poderes.En último lugar, los valores que la legislación urbanística española incorpora, tales como, el desarrollo sostenible, urbanismo sostenible y la cohesión social, quedan inaplicados si las sentencias urbanísticas no se ejecutan.

Modelling the construction projects using plans of work

An overview of organization in the construction industry is identified from plans of work published in the UK. This provides a basis for identifying the essential steps through which any construction project must pass. It is shown that all construction projects pass through a set of stages of work, consisting of inception, feasibility, scheme design, detail design, contract formation, construction and commissioning. Although there may be changes to the sequence and importance of these stages, their identification helps in making judgements about organizational structure on construction projects.

Some new three-level orthogonal main effects plans robust to model uncertainty

In this paper, we list some new orthogonal main effects plans for three-level designs for 4, 5 and 6 factors in IS runs and compare them with designs obtained from the existing L-18 orthogonal array. We show that these new designs have better projection properties and can provide better parameter estimates for a range of possible models. Additionally, we study designs in other smaller run-sizes when there are insufficient resources to perform an 18-run experiment. Plans for three-level designs for 4, 5 and 6 factors in 13 to 17 runs axe given. We show that the best designs here are efficient and deserve strong consideration in many practical situations.

E-commerce system simulation for construction and demolition waste exchange

This article introduces a quantitative approach to e-commerce system evaluation based on the theory of process simulation. The general concept of e-commerce system simulation is presented based on the considerations of some limitations in e-commerce system development such as the huge amount of initial investments of time and money, and the long period from business planning to system development, then to system test and operation, and finally to exact return; in other words, currently used system analysis and development method cannot tell investors about some keen attentions such as how good their e-commerce system could be, how many investment repayments they could have, and which area they should improve regarding the initial business plan. In order to exam the value and its potential effects of an e-commerce business plan, it is necessary to use a quantitative evaluation approach and the authors of this article believe that process simulation is an appropriate option. The overall objective of this article is to apply the theory of process simulation to e-commerce system evaluation, and the authors will achieve this though an experimental study on a business plan for online construction and demolition waste exchange. The methodologies adopted in this article include literature review, system analysis and development, simulation modelling and analysis, and case study. The results from this article include the concept of e-commerce system simulation, a comprehensive review of simulation methods adopted in e-commerce system evaluation, and a real case study of applying simulation to e-commerce system evaluation. Furthermore, the authors hope that the adoption and implementation of the process simulation approach can effectively support business decision-making, and improve the efficiency of e-commerce systems.

Adapting to climate change impacts on water resources in England - an assessment of draft Water Resources Management Plans

Climate change is expected to produce reductions in water availability in England, potentially necessitating adaptive action by the water industry to maintain supplies. As part of Ofwat's fifth Periodic Review (PR09), water companies recently released their draft Water Resources Management Plans, setting out how each company intends to maintain the balance between the supply and demand for water over the next 25 years, following Environment Agency guidelines. This paper reviews these plans to determine company estimates of the impact of climate change on water supply relative to other resource pressures. The approaches adopted for incorporating the impact in the plans and the proposed management solutions are also identified. Climate change impacts for individual resource zones range from no reductions in deployable output to greater than 50% over the planning period. The estimated national aggregated loss of deployable output under a “core” climate scenario is ~520 Ml/d (3% of deployable output) by 2034/35, the equivalent of the supply of one entire water company (South West Water). Climate change is the largest single driver of change in water supplies over the planning period. Over half of the climate change impact is concentrated in southern England. In extreme cases, climate change uncertainty is of the same magnitude as the change under the core scenario (up to a loss of ~475 Ml/d). 44 of the 68 resource zones with available data are estimated to have a climate change impact. In 35 of these climate change has the greatest impact although in 10 zones sustainability reductions have a greater impact. Of the overall change in downward pressure on the supply-demand balance over the planning period, ~56% is accounted for by increased demand (620 Ml/d) and supply side climate change accounts for ~37% (407 Ml/d). Climate change impacts have a cumulative impact in concert with other changing supply side reducing components increasing the national pressure on the supply-demand balance. Whilst the magnitude of climate change appears to justify its explicit consideration, it is rare that adaptation options are planned solely in response to climate change but as a suite of options to provide a resilient supply to a range of pressures (including significant demand side pressures). Supply-side measures still tend to be considered by water companies to be more reliable than demand-side measures.
