A Postscript to Struck by Stereotype

Property valuation of commercial real estates is often seen as complicated. The actors think that their valuation method is the best and the results of the valuation depend on whom you ask. There are many attributes that have to be given a value and information about these attributes is often difficult to get. A possible explanation for these problems is the decline of the transparency in the Swedish real estate market over the last years. Essential information about commercial real estates is lost because they are traded as companies. This makes it problematic to make optimal valuations. The co-operative apartment market is very different from the commercial real estate market. The transparency is high and the transactions are many. The prices in the co-operative apartment market continue to rise and they are much easier to valuate. The purpose of this thesis is to see if there is a connection between market values in the condominium market and market values for office buildings. If a connection is found it may be helpful in the valuation process of office buildings. The first objective is to look at the ratio square meter co-operative apartment prices divided with square meter office building prices. The first part of the thesis is based on analogy and digital literature. Next part will consist of valuations with yield methods of office buildings and observed transactions. The result of this thesis shows no given connection between office and co-operative apartment prices, but the highest residence prices are found in the same areas with highest office prices. The ratio that is mentioned above was not useful for the purpose. The results have shown the difficulties of finding information and valuating real estate.Värderingar av kontorsfastigheter anses ofta komplicerade. Olika aktörer anser sin värderingsmetod som bäst och resultatet av bedömda värden beror på vem du frågar. Det är många parametrar som kan bedömas och ges ett värde, samtidigt som informationen ofta är svår att få tag i. En anledning till problemet skulle kunna vara den minskning av transparens som skett på svenska fastighetsmarknaden under senare år, troligtvis till följd av att allt fler fastigheter ingår i bolagsförvärv. För att kunna göra en optimal värdering av en kontorsfastighet krävs lättillgänglig information om liknande transaktioner. Därför krävs en öppenhet på kontorsmarknaden som i dag försvårats av tidigare nämnda bolagsförvärv. Tittar man istället på bostadsrättsmarknaden är läget annorlunda. Informationen är lättillgänglig och transaktionerna många. Trots att priserna Stockholmsområdet fortsätter att stiga kan man med relativt hög säkerhet värdera en bostadsrätt. Syftet med denna rapport är att undersöka om det finns någon koppling mellan marknadsvärden på bostadsrättsmarknaden och marknadsvärden kontorsmarknaden. Om denna koppling finns, kan den vara till hjälp vid värdering av kontorsfastigheter. Målet är först och främst att se om kvoten, bostadrättspris dividerat med kontorspris, är användbar. Rapportens första del bygger på analog och digital litteratur. Den andra delen består av värderingar med direktavkastningsmetoden och jämförelser som gjorts med hjälp av aktuella transaktioner och riktvärden. Resultatet visar inget självklart samband mellan priser på bostadsrätter och kontor, men de högsta kontorspriserna återfinns i områden med högst bostadspriser. Det har inte gått att styrka användningen av ovan nämnda kvot. Rapporten har framförallt resulterat i en bekräftelse av de svårigheter informationssökning och värdering av kontor innebär

The Science of Philosophy: Discourse and Deception in Plato’s Sophist

At 252e1 to 253c9 in Plato’s Sophist, the Eleatic Visitor explains why philosophy is a science. Like the art of grammar, philosophical knowledge corresponds to a generic structure of discrete kinds and is acquired by systematic analysis of how these kinds intermingle. In the literature, the Visitor’s science is either understood as an expression of a mature and authentic platonic metaphysics, or as a sophisticated illusion staged to illustrate the seductive lure of sophistic deception. By showing how the Visitor’s account of the science of philosophy is just as comprehensive, phantasmatic and self-concealing as the art of sophistry identified at the dialogue’s outset, this paper argues in favor of the latter view

Two-scale convergence in thin domains with locally periodic rapidly oscillating boundary

The aim of this paper is to adapt the notion of two-scale convergence in $L^p$ to the case of a measure converging to a singular one. We present a specific case when a thin cylinder with locally periodic rapidly oscillating boundary shrinks to a segment, and the corresponding measure charging the cylinder converges to a one-dimensional Lebegues measure of an interval. The method is then applied to the asymptotic analysis of linear elliptic operators with locally periodic coefficients in a thin cylinder with locally periodic rapidly varying thickness.Comment: 13 pages, 1 figur

Sustainable mining, local communities and environmental regulation

Sustainable mining is an objective as well as a tool for balancing economic, social, and environmental considerations. Each of these three dimensions of mining – and sustainable development – has many components, some of which were chosen for closer study in the SUMILCERE project. While there is no single component that in itself provides a definitive argument for or against sustainable mining, the research reveals some that have proven valuable in the process of balancing the different dimensions of sustainability. In the SUMILCERE project, comparative studies enabled us to identify factors such as the following, which are essential when discussing the balancing in practice of the three dimensions of sustainable mining cited above: the framework and functionality of environmental regulation to protect the environment (environmental sustainability); the competitiveness of the mining industry in light of environmental regulation and its enforcement (economic sustainability); public participation and the opportunities local communities have to influence their surroundings, as well as communities’ acceptance of projects (social sustainability) before and during operations; and the protection of Sámi cultural rights in mining projects (social and cultural sustainability). Although each of the three dimensions of sustainability leaves room for discretion in the weight assigned to it, ecological sustainability, protected by smart environmental regulation and minimum standards, sets essential boundaries that leave no room for compromises. Economic and social sustainability are possible only within these limits. Details of the analyses in the Kolarctic area and accounts of the methods used can be found in the cited SUMILCERE articles.publishedVersio

Aphid acceptance of Hordeum genotypes is affected by plant volatile exposure and is correlated with aphid growth

Nineteen genotypes of Hordeum vulgare were characterized as partially resistant or susceptible regarding growth of the bird cherry - oat aphid (Rhopalosiphum padi L.). These genotypes were treated with volatiles from undamaged plants of barley cultivar Alva. Aphid host acceptance (AHA) was significantly affected in seven genotypes, and the magnitude of the effect was positively correlated with aphid growth (AG) in a resistance screening test. Changes in AHA induced by volatiles from the same genotype were also positively correlated with AG. All genotypes were tested as inducers with cultivar Kara as the receiver of volatiles. Five genotypes induced significant reductions in AHA of Kara. The results show that aphids are able to detect changes in responding plants induced by volatiles from another cultivar. Plant volatile interactions may thus be a component of induced resistance to aphids. These interactions could influence the results of experiments used to select for insect-resistant plants in plant breeding programmes

A Large-Scale Comparison of Historical Text Normalization Systems

There is no consensus on the state-of-the-art approach to historical text normalization. Many techniques have been proposed, including rule-based methods, distance metrics, character-based statistical machine translation, and neural encoder--decoder models, but studies have used different datasets, different evaluation methods, and have come to different conclusions. This paper presents the largest study of historical text normalization done so far. We critically survey the existing literature and report experiments on eight languages, comparing systems spanning all categories of proposed normalization techniques, analysing the effect of training data quantity, and using different evaluation methods. The datasets and scripts are made publicly available.Comment: Accepted at NAACL 201
