Stockholm is a city of bridges. But we rarely pay attention to what happens below them. Many of these spaces are centrally located in the city, yet perceived as peripheral due to their uncertain programmatic status and rough physical appearance, also referred to as loose space. Some are integrated in the urban fabric; others are more inaccessible and thus become forgotten spots detached from the rapid development of the rest of the city. The space below the bridges of Skanstull is an example of the latter. After many years of being in the shadow of the city, giving space for outdoor parties, graffiti painters and more recently urban farming, it is now being under pressure of a large scale redevelopment project. But do these spaces carry meaning that is neglected in the common notion of public space? How can we as planners use our tools in order to encourage the existence of a larger diversity of forms, spaces and uses?

Cette étude porte sur le vécu d’individus ayant reçu un diagnostic de déficience intellectuelle et institutionnalisés à l’hôpital psychiatrique Saint-Michel-Archange situé dans la région de Québec à partir de 1951. Adoptant une perspective from below, elle explore le parcours de quatorze patients à partir de leur dossier médical afin de comprendre la sortie tardive de l’institution de plusieurs d’entre eux en pleine période de désinstitutionnalisation. Cette recherche rend compte de vécus complexes, nuancés et multiples à l’extérieur et à l’intérieur des murs de Saint-Michel-Archange. Y sont documentés les aspects plus pénibles de la vie à l’institution et la résistance qu’y opposent nombre de patients, mais aussi l’appréciation qu’expriment plusieurs des soins, loisirs, occupations et relations auxquels ils y avaient accès. C’est en effet avec réticence que certains quittent Saint-Michel-Archange après y avoir vécu pendant plusieurs décennies. Nos sources révèlent par ailleurs différentes lacunes du mouvement de désinstitutionnalisation québécois. Non des moindres sont celles concernant les ressources résidentielles se développant à l’extérieur de l’institution. Vraisemblablement mal adaptées au besoin de plusieurs, certains demandent à revenir à Saint-Michel-Archange après en avoir fait l’expérience. D’autres, en général ceux dont l’autonomie au quotidien est la plus faible, ne quittèrent jamais l’hôpital après leur première admission. Aucun foyer ne paraît avoir été disposé à accueillir des individus aux besoins aussi grands que les leurs. En sommes, cette recherche démontre la pertinence d’un point de vue historique de s’intéresser au vécu de personnes ayant reçu un diagnostic de déficience intellectuelle. Son étude démontre en effet le rôle d’agents actifs qu’ils ont eu dans le cadre de leur institutionnalisation.

Sammanfattning Titel: Billigt eller dyrt, udda eller jämt? - Hur prisprecisionseffekten påverkar Willingness to pay Nivå: Examensarbete på Grundnivå (kandidatexamen) i ämnet företagsekonomi. Författare: Lovisa Axenfalk Pettersson och Wilhelm Ericsson. Handledare: Jonas Kågström. Datum: 2018 - Maj. Syfte: Syftet är att undersöka hur prisprecisionseffekten i samband med Willingness to pay påverkar bostadstransaktioner. Metod: Kvantitativ metod, enkäter med experimentella inslag. Resultat och slutsats: Denna studies resultat visar att när det kommer till priser på bostäder, är det inte enbart priset som påverkar köpet och WTP. Gällande det marknadsförda pris som lockar flest spekulanter, bör det antingen vara avrundat pris eller just below pris. Det mest ärliga marknadsmässiga priset är avrundat pris. Ett precist pris är det utgångspris, som anses vara satt av en seriös fastighetsmäklare och visar att fastighetsmäklaren är kunnig och sätter ett seriöst pris utifrån vad bostaden faktiskt är värd. Gällande vad som leder till det högsta slutpriset, kan det vara avrundat pris, precist pris samt just below pris. Varför resultatet av slutpriset skiljer sig åt är beroende på situationen på marknaden och tillgänglig information för köparen. Examensarbetets bidrag: Denna studie har bidragit med att skapa en ökad förståelse till personer som är delaktiga i en köpprocess utifrån prisprecisionseffektens prissättningar. Vidare är bidraget att människor påverkas av tillgänglig information, vilket påverkar köparens WTP och vad köpare anser om olika priser. Med kunskap från denna studie kan köpare av bostäder få en bättre förståelse för hur det marknadsförda utgångspriset kan påverka köparens WTP av bostaden de är intresserad av att köpa och den bostadens slutpris. Förslag till fortsatt forskning: Studien fastställer att det finns flera möjligheter till fortsatt forskning. Det skulle kunna vara att studera prisprecisionseffekten i en verklig miljö. Att studera hur ankareffekten och prisprecisionseffekten påverkar varandra. Väva in andra prispåverkande faktorer än bara själva priset. Samt att vända perspektiv och utgå från säljaren istället. Nyckelord: Prisprecisionseffekten, WTP - Willingness to pay, avrundat pris, precist pris, just below pris, utgångspris och bostadstransaktioner. / Abstract Title: Cheap or expensive, odd or even? - How the price precision effect, affects willingness to pay Level: Final assignment for Bachelor Degree in Business Administration. Author: Lovisa Axenfalk Pettersson and Wilhelm Ericsson. Supervisor: Jonas Kågström. Date: 2018 - May. Aim: The aim is to further investigate how the price precision effect associated with willingness to pay affects sales of real estate transactions. Method: Quantitative method through a survey with experimental elements. Result and conclusion: The results in the study indicates, regarding prices on the housing market, that it is not only the price that affects pursues and WTP. Regarding the marketed list price, which attracts the most potential buyers, they should either be a rounded or just below price. The most honest market price is a rounded price. A list price set at a precise price, is considered to be listed from a serious real estate broker. It also indicates that the real estate broker is knowledgeable and puts a serious price based on what the residence is actually worth. To get the highest selling price, it can be all of the price precision effect prices, rounded price, precise price or just below price. Why the result of the highest selling price differ, is depending on the situation on the market and available information for the buyer. Contribution of the thesis: The contribution for this study has been to create an increased understanding about the price precision effect and its prices for the persons involved in a buying process. Furthermore, the contribution is that people are influenced by available information, affecting the buyer's WTP and what buyers consider about different prices. With knowledge from this study, buyers can gain a better understanding of how the marketed list price may affect the buyer's WTP for the real estate they are interested in buying and its final selling price. Suggestion for future research: To summarize the possibilities for future research this paper suggests; to analyze the price precision effect from the sellers point of view. To analyze the price precision effect in a real setting instead, where actual transactions are being made. To further investigate the ratio between the anchoring effect with the price precision effect, and how they affect each other. The final suggestions for future research is to involve other aspects into the price precision effect, despite only the price, because it is not only the price that affects the house buying market. Keywords: Price precision effect, WTP - willingness to pay, rounded price, precise price, just below price, list price and real estate transaction.

Public procurement below the lowest threshold This thesis describes and analyses the legal regulations and practice in the Czech public procurement below the lowest threshold. In particular, it focuses on the principles governing the procedures, i.e. transparency, proportionality, equality and non-discrimination. The first chapter deals with the purpose of the Czech Public Procurement Act, the concept and development of the legal regulation of public procurement below the lowest threshold emphasising the financial limits of the contract's value, which separates these public contracts from other procedures. The second chapter deals with the principles that apply to public procurement which represent the source for the regulation of public procurement below the lowest threshold. The law does not define their precise meaning, leaving it to the case law, decisions of the public authorities and opinions of the experts. These principles are necessarily conncected to the principles of financial management known as the 3E. The third chapter focuses on the procedure of contracting authorities during the public procurement. Since contracting authorities may, with certain restrictions, create their own rules for the procedure, the chapter contains examples and evaluation of these regulations of the individual...

Master of Science / Department of Agronomy / David B. Mengel / Nitrogen fertilizers play an essential role in agricultural production in Kansas, particularly in row crops such as corn (Zea mays L.) and grain sorghum (Sorghum bicolor (L.) Moench). A good portion of the corn and grain sorghum grown in Kansas is typically grown using no-till production systems. These systems leave a large amount of surface residue on the soil surface, which can lead to ammonia volatilization losses from surface applied urea-containing fertilizers and immobilization of N fertilizers placed in contact with the residue. Leaching and denitrification can also be a problem on some soils. Current nitrogen prices, as well as concerns over environmental stewardship, are forcing producers to make smarter choices in the fertilizer products used as well as when and how the materials are applied, to optimize their nitrogen use efficiency. A common practice throughout Kansas is to apply N fertilizers prior to planting, sometimes up to 6 month prior to planting. What affect does this practice have on nitrogen availability to the growing crop? Current Kansas State University (KSU) soil test fertilizer recommendations assume 50% nitrogen use efficiency. This means of every pound of nitrogen applied only half will be utilized by the plant and turned into valuable grain. Possible solutions to help increase nitrogen use efficiency are the use of nitrogen additives which are currently on the market and claim to reduce nitrogen loss through denitrification and volatilization as well as the use of timing and application of fertilizers to further increase nitrogen use efficiency. The objective of this study is to evaluate different N fertilizer products, as well as additives and application practices and determine whether specific combinations can improve yield and N use efficiency of no-till corn and grain sorghum. The long-term goal of this study is to quantify some of these relationships to assist farmers in selecting specific combinations that could enhance yield and profitability. In this study five tools for preventing N loss were examined: fertilizer placement, or placing N below the soil surface or in bands on the residue-covered soil surface to reduce immobilization and/or volatilization; use of a urease inhibitor Agrotain (NBPT) that blocks the urease hydrolysis reaction that converts urea to ammonia and potentially could reduce ammonia volatilization; the use of a commercially available additive, Agrotain Plus, that contains both a nitrification inhibitor (DCD) and a urease inhibitor to slow both urea hydrolysis and the rate of ammonium conversion to nitrate and subsequent denitrification or leaching loss; use of a commercial product NutriSphere-N, which claims urease and nitrification inhibition; and the use of a polyurethane plastic-coated urea to delay release of urea fertilizer until the crop can use it. The ultimate goal of using these practices or products is to increase N uptake by the plant and enhance yield. An important measurement that was developed for this research was the use of a greenleaf firing index which used the number of green leaves below the ear at pollination as a key measurement in determining the effectiveness of fertilizer placement, application method, application timing and the use of nitrogen additives. If significant differences in lower leaf nitrogen stress are found, the potential exists to further develop this index and correlate differences observed with key parameters of nitrogen uptake such as ear-leaf nitrogen concentration, total nitrogen uptake and grain yield. Results observed from this research show that the potential to increase nitrogen use efficiency and reduce nitrogen loss do exist with the use of certain nitrogen additives, application methods and application timing. When conditions are conducive for nitrogen loss the use of currently available tools to protect nitrogen from volatilization, immobilization and/or denitrification loss significantly increased yields in the corn experiments. Results from the grain sorghum research indicate that when N losses limit yield, the use of products and practices enhance yield. In locations where nitrogen loss is minimal or low yields limit nitrogen response, the use of these practices was not found to be helpful.

The tropical forests on the island of Borneo are among of the richest in the world in terms of tree diversity, and their capacity to store a large reservoir of carbon. The Southeast Asian forests are fundamentally different from Neotropical and African forests, with their single-family dominance by dipterocarp trees, and with inherently greater stature and biomass. The carbon productivity and allocation in Asian tropical forests is still poorly quantified, and their responses to environmental drivers are still poorly understood. Almost all recent advances in tropical forest carbon cycling research have occurred in the Neotropics, with very few studies in Asia. The principal aim of this thesis is to quantify the carbon budget of a lowland dipterocarp forest in the Lambir Hills National Park, Miri, Sarawak, Malaysian Borneo. I examined and explored the productivity and carbon cycling processes and their responses to environmental factors across two major and contrasting soil types, in particular the clay and sandy loam soils. I recorded and analysed the Net Primary Productivity (NPP) and respiration for the above- and below-ground components, and observed the responses to seasonal variation and environmental drivers. Total soil respiration was relatively high and contributed a great deal to ecosystem respiration. Variation in soil respiration rates appeared closely related to soil moisture content. I found a strong diurnal cycle in soil respiration. On the basis of the first soil carbon dioxide (CO2) efflux partitioning study undertaken in a tropical forest, the diurnal cycle in total soil respiration appeared to be entirely driven by the diurnal cycle in litter respiration, and in turn litter is strongly controlled by moisture. There was little seasonal variation in allocation of net primary productivity (NPP), but there was evidence showing potential inter-annual variability for several components of NPP. Further, the allocation of NPP showed a strong seasonal shift between the forest plots on clay and sandy loam soils. Combining all the data measured and obtained in this D.Phil. thesis, the overall carbon budget assessed in this lowland dipterocarp forest showed a high level of agreement with other studies in Asia using micrometeorological techniques and the situation appears to be comparable to tropical forests in Amazonia. The key difference is that the aboveground NPP is higher and is the largest component contributing to the overall carbon budget, with relatively higher carbon use efficiency (CUE). The lowland dipterocarp forest in Lambir shows higher allocation in the above-ground NPP, and there were also differences in NPP and its allocation between sandy and clay-rich plots.

En cas de rejets de polluants ou de radionucléides dans l’atmosphère, l’estimation du lessivage des particules d’aérosol atmosphérique par les précipitations est une donnée essentielle pour évaluer la contamination de la biosphère. De nombreuses études se sont déjà intéressées à ce processus de dépôt humide, mais la plupart d’entre elles sont d’ordre théoriques ou ont été menées en laboratoire. Cette étude a donc pour objectif d’améliorer la connaissance du potentiel de lessivage des particules d’aérosol par les précipitations par une approche expérimentale en conditions in situ. Durant plusieurs mois, trois sites aux environnements distincts en termes de climatologie et d’empoussièrement ambiant ont été instrumentés pour disposer d’une palette de situations précipitations/empoussièrement la plus variée possible. Un disdromètre laser et un granulomètre (compteur électrique et/ou optique) ont mesurés respectivement les caractéristiques des précipitations et les concentrations de particules à une résolution temporelle élevée et sur une large gamme de diamètre. L’utilisation de ce couplage instrumental original a permis de déterminer les potentiels de lessivage pour des particules de la gamme nanométrique à supermicronique et pour différents types de précipitations (chutes de neige et pluies avec des hyétogrammes spécifiques). Dans un premier temps, le coefficient de lessivage ᴧ (paramètre décrivant la cinétique du processus) a été calculé en considérant l’effet global d’une précipitation. Cette approche « macroscopique » est limitée par l’influence de processus « concurrents », tels que l’advection ou les sources d’émissions de particules à proximité des sites de mesures. Pour minimiser l’impact de ces processus sur nos résultats, une seconde méthodologie basée sur la résolution temporelle élevée de l’instrumentation utilisée a été définie. Par cette approche « intra-évènementielle », les coefficients de lessivage ᴧ sont calculés sur de courtes périodes de temps, permettant ainsi d’étudier l’influence de la variabilité du diamètre des particules et des caractéristiques des précipitations sur ces coefficients. Les résultats obtenus par les deux types d’approches ont mis en évidence la nécessité de prendre en compte le diamètre des particules et les caractéristiques des précipitations pour modéliser fidèlement le lessivage des particules d’aérosol atmosphérique. En comparant les résultats des deux types de précipitations, la prédominance du lessivage par des chutes de neige par rapport au lessivage par la pluie a été illustrée. L’importance du diamètre des particules lessivées a été démontrée. Entre le mode « ultrafin » et le mode « grossiers », la variation du coefficient de lessivage est d’un ordre de grandeur (entre environ 2.10¯³et 2.10¯⁴ s¯¹). Le potentiel de lessivage minimum est obtenu pour des particules d’environ 100 nm, ce qui est cohérent avec la théorie du « Greenfield gap » (entre 0,1 et 1 µm). Pour les besoins de la modélisation, une paramétrisation robuste entre le coefficient de lessivage ᴧ et le diamètre des particules d’aérosol (de 10 nm à 10 µm) a été établie. Différentes relations entre le coefficient ᴧ et l’intensité pluviométrique sont proposées aussi pour différentes gammes de diamètre de particules et comparées notamment aux valeurs implémentées actuellement dans le modèle ldX utilisé à l’Institut de Radioprotection et de Sûreté Nucléaire. / In case of release of pollutant or radionuclides into the atmosphere, estimate of below-cloud scavenging of aerosol particles by precipitation (or washout) is an essential data to evaluate contamination of the biosphere. Many studies have already shown an interest to this wet deposition process, but most of them are theoretical or have been conducted in laboratories conditions. This study in situ conditions aims to improve knowledge of below-cloud scavenging of aerosol particles by precipitation. For several months, three sites with separate environments in terms of climate and ambient dust have been instrumented to have such a varied palette of precipitation/dust conditions as possible. A laser disdrometer and a granulomètre (electrical and/or optical counter) measure respectively precipitations characteristics and particles concentrations with a high temporal resolution (one minute). The use of this original instrumental coupling has allowed determining washout potentials for the nanometric size range of particles aerosol to the supermicronique size range and for different types of precipitation (snowfalls and rainfalls with specifics hyetograms).Initially, below-cloud scavenging coefficients ᴧ (parameter describing kinetic of this process) were calculated considering the gobal effet of a precipitation. This “macroscopic” approach is limited by the influence of “concurrent” processes, as advection or local emissions of aerosol particles close to the measurements sites. To minimise effect of these processes on our results, a second methodology based on the high temporal resolution of the instrumentation used was defined. With this “intra-event” approach, washout coefficients are calculated on short time scales, allowing study of impact of the variability of aerosol size and precipitations characteristics on these coefficients.Results obtained with the two approaches highlighted the need of considering particles diameter and characteristics of precipitation to model accurately below-cloud scavenging of aerosol particles. Comparing results for both type of precipitation, predomination of below-cloud scavenging by snowfalls compared with below-cloud scavenging by rainfalls was shown. The importance of the scavenged aerosol diameter was demonstrated. From the “ultrafine” size range to coarse mode of particles, below-cloud scavenging coefficient varies by an order of magnitude (from 2.10¯³ to 2.10¯⁴ s¯¹). Minimum potential is obtained for particles of about 100 nm, which is consistent with theory of “Greenfield gap” (from 0.1 to 1 µm). For modeling needs, a robust parametrization between washout coefficient ᴧ and aerosol particles diameter (from 10 nm to 10 µm) has been established. Also some relationships between coefficient ᴧ and rainfall intensity are proposed for different particles size range and compared in particular with values implemented in model ldX currently used at the French Institute of Radioprotection and Nuclear Safety.
