Bodnar and Schmid (2008) derived the distribution of the global minimum variance portfolio weights and obtained the distribution of the test statistics for the general linear hypothesis. Their results are obtained in the case when the number of observations n is bigger or equal than the size of portfolio k. In the present paper, we extend the result by analyzing the portfolio weights in a small sa
Spectroscopic investigations of highly charged ions have been performed in the VUV, UV and visible spectral regions using mainly the beam-foil technique. New 2s22px3l levels have been established in N and O-like Si and S, together with many transitions between these levels. Several of these lines have also been identified in the solar corona spectra recorded by the SUMER/SOHO instrument. In Mg-lik
Energy efficiency has gained attention as an important means of ensuring energy supply, fostering countries’ competitiveness and cost-effectively mitigating CO2 emissions. Yet, evaluations of energy efficiency policies are often lacking or insufficient. Moreover, researchers have tended to overlook these types of policies in non-OECD countries, although at this very moment many of these countries
An audio-tactile interactive tourist guide is demonstrated, including the possibility to be guided to points of interest. In contrast with the key-hole like experience of on-screen augmented reality, this guide makes use of the non-visual modalities to create a more immersive augmented experience. Sound windows from the past and verbal historical information complement discrete tactile guidance al
I en berömd formulering skriver den amerikanske sociologen Howard S. Becker (1963/1991: 17) att avvikande inte ska ses som vare sig patologiskt (sjukligt) definierat eller statistiskt definierat; det är i stället en fråga om regelbrott. Den som avviker bryter mot en uttalad eller underförstådd regel. Vidare skapas regler på särskilda sätt i samhället, menar Becker: vuxna gör regler för barn, män g

The aim of this research is to analyze the cinematographic image of lesbianism in Spanish cinema by critically analyzing and evaluating full-length films produced in Spain from 1972 to 2005 starring lesbian characters. The analysis model that has been used was developed by J.C. Alfeo (1997) in his work about film representation of male homosexuality and it is based on S. Chatman (1990) and P. Hamm
We present the first results of a detailed abundance analysis, based on VLT observations, of giant stars in the very metal-rich globular cluster NGC 6528. We will be able to tie the horizontal branch abundances (see e.g. Carretta et al. 2001) to those of the more luminous giants (see CMDs). For the very similar cluster NGC 6553 studies of different types of stars have yielded very disparate result
Popular AbstractAvhandlingen undersöker relationen mellan individer och platser relaterat till livskriser och existentiell trygghet. Författaren analyserar olika copingstrategier hos gravida kvinnor och hur detta förändrar deras relation till olika platser i deras livshistoria. Anthony Giddens begrepp ontologisk trygghet granskas kritiskt i förhållande till existentiell välmående och används sedanThe study explores the importance of place attachment on individuals? sense of security during existential crises. Coping strategies of pregnant women are analysed, focusing on how the prospect of giving birth affects their relationship to place. Anthony Giddens? concept of ontological security is critically examined and used to investigate the connection between place and ontological security ? w
