Article Nine of Japan’s Constitution: From Renunciation of Armed Force “Forever” to the Third Largest Defense Budget in the World

Each year approximately 2,000 new detailed development plans are accepted in Sweden. When an area is covered by a new detailed development plan, it is often necessary that land has to be acquired to adjust the property units to the new plan. The owner conditions of the property units can usually be adjusted through negotiations between the seller and the buyer. But in some situations, when no agreements can be reached, it is possible to use coercive measures to purchase the land. Compulsory purchases are only permitted when certain legal criteria’s are met. The legal ability of compulsory purchases also affects voluntary negotiations since they function as "game rules". The compensations that are given in compulsory purchases then functions as a sort of minimum level of the compensations given in voluntary negotiations. The purpose of this thesis is to study the compensation that should be given in different situations when land is being compulsory purchased. Furthermore, the purpose is also to study the motives behind the legislation regarding compulsory purchases. In order to find an answer to the purpose of this thesis, a study has been made with a representative property unit. In the study, land was taken with coercive measures in four different situations from the property unit when a new detailed development plan covered the property unit. The four different situations were chosen to illustrate the differences between the given compensations. In the four different situations two different legal systems were applied. First, the existing legal system in Sweden was applied and then an alternative system based on principles that earlier could be found in the, now no longer existing, Act regarding development cooperation units (SFS 1987:11, lag om exploateringssamverkan) was applied. The result of the study shows that the compensation given depends upon the allowed land use in the new detailed development plan and upon which legal system that is applied. In the current Swedish legal system, the allowed land use for the specific property unit in the detailed development plan had the largest impact on the compensation given. In the alternative system, the total allowed land use in the detailed development plan was of importance for the given compensation together with what the property owner had contributed to the development area.Varje år antas cirka 2000 detaljplaner i Sverige. När ett område detaljplaneläggs behöver mark vanligtvis förvärvas för att anpassa fastigheterna till de nya förhållandena. Ägarförhållandena kan vanligtvis anpassas via förhandlingar mellan köpare och säljare. Men i vissa situationer, om ingen överenskommelse kan nås, är det tillåtet att använda tvångsregler för att förvärva marken. Tvångsreglerna får bara användas när kriterier uppställda i lagen är uppfyllda. Även vid frivilliga förhandlingar fyller tvångsreglerna en funktion eftersom de då fungerar som spelregler. Lagstiftningens ersättningsbestämmelser utgör en slags miniminivå för ersättningens storlek. Syftet med denna uppsats är dels att studera vilken ersättning som betalas i olika situationer när mark tvångsförvärvas inom detaljplanelagt område och dels att studera de motiv som ligger till grund för lagstiftningens utformning. För att besvara syftet har en typfallsstudie genomförts där mark frångick en typfastighet för fyra olika markåtkomstsituationer när en ny detaljplan blev gällande över området. Situationerna valdes för att tydliggöra att ersättningen som utgår vid olika markåtkomstsituationer kan variera. I studien tillämpades både dagens ersättningssystem samt ett konstruerat ersättningssystem som baserades på den upphävda lagen om exploateringssamverkan (ESL). Framkomna resultat visar att ersättningen kan variera dels beroende av vad marken ska användas till och dels beroende av vilket ersättningssystem som tillämpas. I det nu gällande ersättningssystemet är den största påverkan på ersättningen vad marken får användas till enligt detaljplanen. I det alternativa ersättningssystemet är det detaljplanens totala utformning som styr ersättningsbeloppet tillsammans med vad respektive fastighetsägare bidragit med till planområdet

Does providing childcare to unemployed affect unemployment duration?

This paper examines if the probability of leaving unemployment changes for unemployed parents with young children when childcare is available. To investigate this, I use the heterogeneity among Swedish municipalities before the implementation of a 2001 Swedish childcare reform making it mandatory for municipalities to offer child¬care to unemployed parents for at least 15 hours per week. In the study difference-in-differences and difference-in-difference-in-differences methods are used. The results indicate a positive effect on the probability of leaving unemployment for mothers when childcare is available, but no effect is found for fathers. For mothers, some heterogeneous effects are also found, with a greater effect on the probability of leaving unemployment for work when childcare is available for mothers with only compulsory schooling or university education and mothers with two children.Unemployment duration; childcare

Hidden Negative Energies in Strongly Accelerated Universes

We point out that theories of cosmological acceleration which have equation of state, w, such that 1+w is small but positive may still secretly violate the null energy condition. This violation implies the existence of observers for whom the background has infinitely negative energy densities, despite the fact that the perturbations are free of ghosts and gradient instabilities.Comment: 5 pages, 1 figure. v2 reflects version accepted for publication in PRD.

Dark Matter via Many Copies of the Standard Model

We propose a cosmological scenario based on the assumption that the Standard Model possesses a large number of copies. It is demonstrated that baryons in the hidden copies of the standard model can naturally account for the dark matter. The right abundance of the hidden-sector baryons and the correct spectrum of density perturbations are simultaneously generated during modulated reheating. We show that for the natural values of inflaton coupling constants, dictated by unitarity, the dark-matter abundance is predicted to be proportional to the ratio of observed cosmological parameters: the square of the amplitude of cosmological perturbations and the baryon-to-photon number ratio.Comment: 11 pages, 2 figure

B-Inflation

We propose a novel model of inflation based on a large class of covariant effective actions containing only the second derivatives of a scalar field. The initial conditions leading to the inflationary solutions in this model are rather generic. The graceful exit from the inflationary regime is natural once the first order derivative terms are included.Comment: 21 pages,10 figures, references added, Fig.1 slightly corrected, discussion about stability is extende

Looking beyond the horizon

In this short talk we review our results from the paper hep-th/0604075 with the main stress on the issues of causality and acoustic metric in eikonal approximation. In addition we correct the formula for the redshift of sound signals from our original work. We show that, if there exists a special kind of Born-Infeld type scalar field, then one can send information from inside a black hole. This information is encoded in perturbations of the field propagating in non-trivial scalar field backgrounds, which serve as a "new ether". Although the action of the theory is manifestly Lorentz-invariant the non-trivial solutions break this symmetry spontaneously, allowing, the superluminal propagation of perturbations with respect to this "new ether". We found the stationary solution for background, which describes the accretion of the scalar field onto a black hole. Examining the propagation of small perturbations around this solution we show that the signals emitted inside the Schwarzschild horizon can reach an observer located outside the black hole. Thus the accreting field forms a hydrodynamical analog of a black hole whose horizon is inside of the gravitational black hole drawing in the scalar field.Comment: To appear in the proceedings of 11th Marcel Grossmann Meeting on Recent Developments in Theoretical and Experimental General Relativity, Gravitation, and Relativistic Field Theories, Berlin, Germany, 23-29 Jul 200
