Implementation of International Programmes in Developing Countries : the Example of SAICM in TanzaniaLindgren, Johan, Adolfsson, Martin January 2008 (has links)
<p>The Strategic Approach to International Chemicals Management (SAICM) is an international framework on sound chemicals management with the objective that “by the year 2020, chemicals are produced and used in ways that minimize significant adverse impacts on the environment and human health”. SAICM was adopted at the International Conference on Chemicals Management in Dubai, United Arab Emirates, in February 2006. To prepare countries to be able to implement SAICM the United Nations Institute for Training and Research (UNITAR) is currently running Pilot Projects in three developing countries and one county with economy in transition: Belarus, Pakistan, Tanzania and Panama. Between October and December 2007 we were doing a Minor Field Study in Dar es Salaam, Tanzania, interviewing people involved in the implementation of their Pilot Project which is running from 2006-2009. Our paper consists of two parts, one descriptive and one analysing. In the first part we describe the initiation, the formulation, the implementation and the evaluation of SAICM and the Pilot Project in Tanzania and in the second part we analyse opportunities and hindrances for a successful implementation of the Pilot Project and SAICM in Tanzania. How is the UN governing the implementation, what resources of finances, knowledge, institutions and time does Tanzania have and how is the implementation influenced by different actors interests? We argue that the there is mixture of the top-down and the bottom-up models and that this mixture is fruitful, we argue that Tanzania has enough finances, knowledge and time to implement SAICM but lack institutions, and finally that the different interests are not too various to harm the process.</p>

The Complexity of Splay Trees and Skip Lists.Sayed, Hassan Adelyar. January 2008 (has links)
<p>Our main results are that splay trees are faster for sorted insertion, where AVL trees are faster for random insertion. For searching, skip lists are faster than single class top-down splay trees, but two-class and multi-class top-down splay trees can behave better than skip lists.</p>

Exploring Impulsive Activation During Spoken Language ComprehensionTsang, Cara Kar Lee 07 January 2013 (has links)
A language comprehension mechanism that immediately starts processing language as it is encountered is typically thought of as one that speeds and facilitates spoken language comprehension. However, there exist cases where the earliest parts of a word or phrase encode information that is somewhat at odds with the remainder of the word or phrase in full. Examples of these "potentially misleading" cases include compound words where the initial subpart of the compound belongs to a different syntactic category than the entire compound (e.g., "popcorn", "greyhound"), or noun phrases where the initial element of the phrase signals perceptual properties possessed by the referent of the noun phrase (e.g., some Chinese Cantonese classifier-noun phrases).
Using a visual-world methodology, this dissertation explores the kinds of unintended or "impulsive" activation that are triggered when listeners encounter such cases, as well as how syntactic and contextual cues can constraining this impulsive activation. Experiment 1 examines whether hearing compound subparts (e.g., "pop-" in "popcorn") activates conceptual associates across syntactic categories, and Experiment 2 examines whether this activation is moderated by listeners' expectations about the syntactic structure of the sentences they encounter. Experiments 3 and 4 investigate the processing of compounds whose initial subparts correspond to colour terms (e.g., "greyhound"). Experiment 3 explores whether these colour subparts trigger the activation of phrasal-level descriptions of non-target objects in the visual display, and whether this activation is influenced by the presence/absence of motivation to use colour descriptions when naming screen objects. Experiment 4 further explores whether a perceptual mismatch between a target object and the colour term in its name increases this impulsive activation. Finally, Experiment 5 investigates whether listeners use the perceptual information encoded in pre-nominal classifiers in Cantonese Chinese to guide their consideration of referential candidates whose perceptual properties do or do not match the classifier semantics.
The findings from this dissertation point to the highly interactive nature of spoken language comprehension, suggesting that the kinds of impulsive activation under current discussion are rampant and automatic, but can also be suppressed to varying degrees by the syntactic, semantic, and contextual cues available to the listener.

Introduction de non linéarités et de non stationnarités dans les modèles de représentation de la demande électrique résidentielleGrandjean, Arnaud 10 January 2013 (has links) (PDF)
La problématique développée dans la thèse est d'estimer, dans une démarche prospective et dans un but d'anticipation, les impacts en puissance induits par les ruptures technologiques et comportementales qui ne font pas aujourd'hui l'objet de mesures dans les panels. Pour évaluer les modifications sur les appels de puissance du parc résidentiel engendrées par ces profondes transformations,un modèle paramétrique, bottom-up, techno-explicite et agrégatif est donc nécessaire. Celui-ci serait donc destiné à la reconstitution, de manière non tendancielle, de la courbe de charge électrique résidentielle. Il permettrait ainsi de conduire la simulation de différents scénarios d'évolution contrastés. L'élaboration d'un tel modèle constitue le sujet de ce doctorat.Pour répondre à cette problématique, nous proposons une méthode conceptuelle originale de reconstitution de courbe de charge. Sa mise en application centrée sur la génération de foisonnement d'origine comportementale a conduit à la modélisation d'un certain nombre de concepts. Ce travail a abouti à l'élaboration d'un algorithme stochastique destiné à représenter le déclenchement réalistedes appareils domestiques. Différents cas d'application ont pu être testés et les résultats en puissance ont été étudiés. Plus particulièrement pour analyser le foisonnement visible à un niveau agrégé, nous avons mis en place une méthodologie nouvelle basée sur une distance adaptée aux courbes de charge. Finalement, nous avons cherché à identifier des comportements réels d'usage des appareils. Pour cela, nous avons conduit différents travaux de classification de courbes de charge.

Från biståndsbeslut till genomförandeplan : En studie i hur implementeringen går till i ett boendestöds beslutFrisenbrink, Rickard, Legén, Robert January 2011 (has links)
Enligt socialstyrelsens rekommendationer bör varje kommun uppföra genomförandeplaner för de invånare som har en insats genom Socialtjänstlagen (SoL). För att få en insats genom SoL skall en handläggare göra en utredning som ligger till underlag för ett eventuellt beviljande av insats. Syftet med studien är att beskriva och analysera hur informationen förmedlas mellan de personer som är delaktiga i uppförandet av biståndsbeslut och genomförandeplaner inom boendestöd. Vi har studerat detta genom att granska dokumentationen i boendestödsbeslut och intervjuat de personer som är med och upprättar dessa dokument.Frågorna som vi vill ha besvarade i studien är:• • •Hur sker implementeringen av ett biståndsbeslut? Vilken hänsyn tas till brukaren vid upprättandet av dokumentationen? Hur ser dokumentationen ut och hur förhåller sig genomförandeplanen till biståndsbeslutet?Implementeringen sker i ett ständigt informationsflöde mellan de inblandade aktörerna och det som i stor utsträckning styr vad som dokumenteras i genomförandeplanen är informationen och viljan från brukaren. Beslutet kan skilja gentemot genomförandeplanen p.g.a. att ny information har tillkommit när arbetet med uppförandet av genomförandeplanen pågått.

Energy Use in the EU Building Stock - Case Study: UKArababadi, Reza January 2012 (has links)
Previous studies in building energy assessmnet have made it clear that the largest potential energy efficiency improvements are conected to the retrofitting of existing buildings. But, lack of information about the building stock and associated modelling tools is one of the barriers to assessment of energy efficiency strategies in the building stocks. Therefore, a methodology has been developed to describe any building stock by the means of archetype buildings. The aim has been to assess the effects of energy saving measures. The model which is used for the building energy simulation is called: Energy, Carbon and Cost Assessment for Buildings Stocks (ECCABS). This model calculated the net energy demand aggregated in heating, cooling, lighting, hotwater and appliances. This model has already been validated using the Swedish residential stock as a test case. The present work continues the development of the methodology by focusing on the UK building stock by discribing the UK building stock trough archetype buildings and their physical properties which are used as inputs to the ECCABS. In addition, this work seekes to check the adequacy of applying the ECCABS model to the UK building stock. The outputs which are the final energy use of the entire building stock are compared to data available in national and international sources. The UK building stoch is described by a total of 252 archetype buildings. It is determined by considering nine building typologies, four climate zones, six periods of construction and two types of heating systems. The total final energy demand calculated by ECCABS for the residential sector is 578.83 TWh for the year 2010, which is 2.6 % higher than the statistics provided by the Department of Energy and Climate Change(DECC). In the non-residential sector the total final energy demand is 77.28 TWh for the year 2009, which is about 3.2% lower than the energy demand given by DECC. Potential reasons which could have affected the acuracy of the final resualts are discussed in this master thesis.

Local dynamics and external drivers of agro-ecological change in Southwestern EthiopiaHedtjärn Swaling, Julia January 2012 (has links)
While previous research on African smallholder agriculture has been criticized of focusing on the sole factor of population pressure as driver of agricultural degradation or intensification, the present study tries to nuance this debate by providing empirically grounded research, exploring the dynamics behind local agro-ecological change. The thesis specifically studies the dynamics behind small-scale farmers’ crop choices in relation to their management of trees in cropland in Gera District, Ethiopia. Drawing on situated landscape interviews and focus group discussions with farmers combined with observations and interviews with agriculture officials, a contextual understanding of local agro-ecological processes emerged. While political ecology was used as an overarching framework, the concept of landesque capital served as an analytical tool to explore how external and local forces interact at the point of the land management decision. It was found that external factors sometimes have a reinforcing effect at the local scale, but when top-down interventions are incoherent with bottom-up priorities, a conflict occurs. In this way, local dynamics and external drivers constitute an interacting dialectic, with a set of unintentional synergies and trade-offs eventually forming agro-ecological landscape change. / Examining mismatches between management and the supply of ecosystem services in Ethiopian agroecosystems across scales in space and time
