Towards a Network Government? A critical analysis of current assessment methods for e-Government

Contemporary public administrations have become increasingly more complex, having to cordinate actions with emerging actors in the public and the private spheres. In this scenario the modern ICTs have begun to be seen as an ideal vehicle to resolve some of the problems of public administration. We argue that there is a clear need to explore the extent to which public administrations are undergoing a process of transformation towards a netowork government linked to the systematic incorporation of ICTs in their basic activities. Through critically analysing a selection of e-government evaluation reports, we conclude that research should be carried out if we are to build a solid government assessment framework based on network-like organisation characteristics.

Disseny d'un mètode de valoració d'itineraris d'educació ambiental i aplicació a l'àmbit Parc Natural de l'Alt Pirineu - Alt Urgell

El Parc Natural de l’Alt Pirineu (PNAP) està creant una xarxa d’itineraris d’educació ambiental amb l’objectiu de divulgar els valors del parc i conscienciar els seus visitants sobre la importància de conservar el medi ambient. El desenvolupament de mètodes de valoració de l’aptitud de potencials itineraris d’educació ambiental pot servir per crear eines de gestió molt útils a l’hora d’ampliar aquesta xarxa de senders. Per aquest motiu, un grup anterior de la llicenciatura de Ciències Ambientals va desenvolupar el preprotocol Neret, que permet obtenir una puntuació numèrica per a un itinerari, responent a una sèrie de preguntes senzilles. En el present projecte, s’ha aplicat el protocol anterior a tres itineraris de muntanya per tal d’estudiar-ne el funcionament en un tipus d’itinerari diferent dels de fons de vall, on va ser dissenyat. L’anàlisi del preprotocol s’ha efectuat mitjançant una matriu DAFO, a partir de la qual s’han proposat una sèrie d’estratègies de millora i, a partir d’aquestes, s’ha desenvolupat un nou mètode de valoració. Els principals aspectes negatius del preprotocol són la seva manca de flexibilitat, la sobrevaloració dels criteris relacionats amb la dificultat del recorregut, la manca de detall en l’anàlisi del potencial interpretatiu dels itineraris a més del poc pes que té aquest criteri en la puntuació global i, finalment, l’absència d’un criteri que valori els potencials impactes que es podrien derivar de l’ús de l’itinerari. Aquestes mancances s’han mirat de corregir al mètode de valoració dissenyat en el present projecte mitjançant les següents aportacions: una estructura transversal dividida en quatre factors avaluats per separat, sense criteris de valoració excloents i amb una ponderació final dels quatre principals criteris modificable segons els objectius dels gestors; una valoració més detallada dels continguts de l’itinerari, i finalment, la inclusió d’un nou criteri que considera la vulnerabilitat del medi a qualsevol tipus d’impacte.

Assessment in CLIL

The aim of this talk is to explore assessment in higher education and support for learners during their academic education. It investigates the assessment methods that provide success for universities and learners. Universities which implement CLIL should assess learners who would like to attend a programme in English without taking account of their English language qualifications. This assessment should be done in writing, listening and comprehension, speaking and reading and comprehension. In the literature, formative and summative assessments are considered. Formative assessment is ongoing, 'more complex as its intention is to be directly diagnostics with a view to immediately impacting on learner's next steps' (Coyle et al, 2010). Summative assessment occurs at the end of the term or course. McKay, 2006 divides assessment into three phases: design, operationalization and administration phase. If these three phases can't be embedded in the classroom as they are, they can be introduced as a set of questions; why?, how? and what?

Impacto de las proliferaciones de medusas en la valoración económica ambiental de las playas de Denia (Sudoeste Mediterráneo), Alicante, España

El actual incremento de medusas en las costas mediterráneas, percibido como un factor negativo en la calidad de las playas, supone un factor reductor de la demanda turística en las ubicaciones costeras, sobre todo en aquellas más afectadas por éstas proliferaciones. Debido a que la época de mayor presencia de fitoplacton disponible (principal fuente de alimento de las medusas), relacionada a la alta incidencia lumínica, coincide con la temporada alta de turismo en el verano; las notificaciones de incidencias por picaduras de medusa en esta época son frecuentes. Ejemplo de ello, es el caso de Denia (Alicante, España) donde, desde 2008, se ha detectado un considerable aumento de incidencias sanitarias a causa de picaduras de medusa, paralela a la aparición de la especie invasora de cubomedusa Carybdea marsupialis (Bordehore et al, 2011). En este estudio se ha realizado una valoración económica de la playa como un bien ambiental recreativo, mediante encuestas semi-estructuradas elaboradas por Paulo Nunes (CIESM), aplicadas a una muestra inicial de 300 individuos; y evaluado cual sería el impacto social y económico en la valoración ambiental de Denia, si las proliferaciones de medusa no se estabilizaran. Se ha estimado el valor económico del impacto sicial causado por las bioinvasiones marinas en las playas recreacionistas según Nunes and Van den Bergh (2004) y Nunes and Markandya (2008); el método que también ha sido aplicado en el mismo estudio aplicado en Israel (B. Galil, J. Gowdy and P. Nunes 2012) y en Cataluña (2013, Paulo Nunes, M. Loureiro, L. Piñol, S. Sastre, L. Voltaire). En ambos casos los resultados en el impacto económico son considerables pero menores a los esperados, al igual que en los resultados obtenidos en Denia (Alicante).

Ecological economics

Ecological economics is a recently developed field, which sees the economy as a subsystem of a larger finite global ecosystem. Ecological economists question the sustainability of the economy because of its environmental impacts and its material and energy requirements, and also because of the growth of population. Attempts at assigning money values to environmental services and losses, and attempts at correcting macroeconomic accounting, are part of ecological economics, but its main thrust is rather in developing physical indicators and indexes of sustainability. Ecological economists also work on the relations between property rights and resource management, they model the interactions between the economy and the environment, they study ecological distribution conflicts, they use management tools such as integrated environmental assessment and multi-criteria decision aids, and they propose new instruments of environmental policy.

Modelling nitrogen and phosphorus loads in a Mediterranean river catchment (La Tordera, NE Spain)

Human activities have resulted in increased nutrient levels in many rivers all over Europe. Sustainable management of river basins demands an assessment of the causes and consequences of human alteration of nutrient flows, together with an evaluation of management options. In the context of an integrated and interdisciplinary environmental assessment (IEA) of nutrient flows, we present and discuss the application of the nutrient emission model MONERIS (MOdelling Nutrient Emissions into River Systems) to the Catalan river basin, La Tordera (north-east Spain), for the period 1996–2002. After a successful calibration and verification process (Nash-Sutcliffe efficiencies E=0.85 for phosphorus and E=0.86 for nitrogen), the application of the model MONERIS proved to be useful in estimating nutrient loads. Crucial for model calibration, in-stream retention was estimated to be about 50 % of nutrient emissions on an annual basis. Through this process, we identified the importance of point sources for phosphorus emissions (about 94% for 1996–2002), and diffuse sources, especially inputs via groundwater, for nitrogen emissions (about 31% for 1996–2002). Despite hurdles related to model structure, observed loads, and input data encountered during the modelling process, MONERIS provided a good representation of the major interannual and spatial patterns in nutrient emissions. An analysis of the model uncertainty and sensitivity to input data indicates that the model MONERIS, even in data-starved Mediterranean catchments, may be profitably used by water managers for evaluating quantitative nutrient emission scenarios for the purpose of managing river basins. As an example of scenario modelling, an analysis of the changes in nutrient emissions through two different future scenarios allowed the identification of a set of relevant measures to reduce nutrient loads.

Investigating university students' adaptation to digital learner course portfolio

Digital learner portfolios are of growing importance in higher education as the sector seeks new teaching-learning-assessment methods which promote students" autonomy as managers of their own virtual learning environment. The purpose of this study was to analyse descriptively the undergraduate students" perceptions, attitudes and behaviour when using an eportfolio to support their learning and assessment in practice based courses at two traditional Spanish universities. The participants were 88 students, who were studying through a blended learning mode. Data were collected through questionnaires: a computer experience survey, another which examined the psychological, pedagogical and technological dimensions of eportfolios use. Further, an individual overall reflection was obtained from each student to help gain an understanding of their experiences of using the eportfolio. A mixed-method analysis was applied in order to study the impact of this technological innovation on students and their satisfaction. The results showed that the students had positive opinions and self-efficiency through the eportfolio as a tool to manage their learning and assessment during a semester, especially from the second month of use. However, the expected impact on their learning was not so significant. Nevertheless, the students emphasised that the eportfolio was valuable as a personal developmental learning tool.

Empirical studies in industrial location: an assessment of their methods and results

This paper surveys recent evidence on the determinants of (national and/or foreign) industrial location. We find that the basic analytical framework has remained essentially unaltered since the early contributions of the early 1980's while, in contrast, there have been significant advances in the quality of the data and, to a lesser extent, the econometric modelling. We also identify certain determinants (neoclassical and institutional factors) that tend to provide largely consistent results across the reviewed studies. In light of this evidence, we finally suggest future lines of research.

pH Sensitive surfactants from lysine: assessment of their cytotoxicity and environmental behavior

The toxicity and environmental behavior of new pH-sensitive surfactants from lysine are presented. Three different chemical structures are studied: surfactants with one amino acid and one alkyl chain, surfactants with two amino acids on the polar head and one alkyl chain, and gemini surfactants. The pH sensitivity of these compounds can be tuned by modifying their chemical structures. Cytotoxicity has been evaluated using erythrocytes and fibroblast cells. The toxic effects against these cells depend on the hydrophobicity of the molecules as well as their cationic charge density. The effect of hydrophobicity and cationic charge density on toxicity is different for each type of cells. For erythrocytes, the toxicity increases as hydrophobicity and charge density increases. Nevertheless, for fibroblasts cationic charge density affects cytotoxicity in the opposite way: the higher charge density, the lower the toxicity. The effect of the pH on hemolysis has been evaluated in detail. The aquatic toxicity was established using Daphnia magna. All surfactants yielded EC50 values considerably higher than that reported for cationic surfactants based on quaternary ammonium groups. Finally, their biodegradability was evaluated using the CO2 headspace test (ISO 14593). These lysine derivatives showed high levels of biodegradation under aerobic conditions and can be classified as"readily biodegradable compounds".

Optimization of analytical methods for the assessment of the quality of fats and oils used in continuous deep fat frying

La aplicabilidad, repetibilidad y capacidad de diferentes métodos de análisis para discriminar muestras de aceites con diferentes grados de oxidación fueron evaluadas mediante aceites recogidos en procesos de fritura en continuo en varias empresas españolas. El objetivo de este trabajo fue encontrar métodos complementarios a la determinación del índice de acidez para el control de calidad rutinario de los aceites de fritura empleados en estas empresas. La optimización de la determinación de la constante dieléctrica conllevó una clara mejora de la variabilidad. No obstante, excepto en el caso del índice del ATB, el resto de métodos ensayados mostraron una menor variabilidad. La determinación del índice del ATB fue descartada ya que su sensibilidad fue insuficiente para discriminar entre aceites con diferente grado de oxidación. Los diferentes parámetros de alteración determinados en los aceites de fritura mostraron correlaciones significativas entre el índice de acidez y varios parámetros de oxidación diferentes, como la constante dieléctrica, el índice de p-anisidina, la absorción al ultravioleta y el contenido en polímeros de los triacilgliceroles. El índice de acidez solo evalúa la alteración hidrolítica, por lo que estos parámetros aportan información complementaria al evaluar la alteración termooxidativa.

Inclusion of soil erosion impacts in life cycle assessment on a global scale: application to energy crops in Spain

Purpose: Despite the fundamental role of ecosystem goods and services in sustaining human activities, there is no harmonized and internationally agreed method for including them in life cycle assessment (LCA). The main goal of this study was to develop a globally applicable and spatially resolved method for assessing land-use impacts on the erosion regulation ecosystem service.Methods: Soil erosion depends much on location. Thus, unlike conventional LCA, the endpoint method was regionalized at the grid-cell level (5 arc-minutes, approximately 10×10 km2) to reflect the spatial conditions of the site. Spatially explicit characterization factors were not further aggregated at broader spatial scales. Results and discussion: Life cycle inventory data of topsoil and topsoil organic carbon (SOC) losses were interpreted at the endpoint level in terms of the ultimate damage to soil resources and ecosystem quality. Human health damages were excluded from the assessment. The method was tested on a case study of five three-year agricultural rotations, two of them with energy crops, grown in several locations in Spain. A large variation in soil and SOC losses was recorded in the inventory step, depending on climatic and edaphic conditions. The importance of using a spatially explicit model and characterization factors is shown in the case study.Conclusions and outlook: The regionalized assessment takes into account the differences in soil erosion-related environmental impacts caused by the great variability of soils. Taking this regionalized framework as the starting point, further research should focus on testing the applicability of the method trough the complete life cycle of a product and on determining an appropriate spatial scale at which to aggregate characterization factors, in order to deal with data gaps on location of processes, especially in the background system. Additional research should also focus on improving reliability of the method by quantifying and, insofar as it is possible, reducing uncertainty.
