The composition of the labour force is an important economic factor for a country. Often the changes in proportions of different groups are of interest. In this paper we study a monthly compositional time series from the Swedish Labour Force Survey from 1994 to 2005. Three models are studied: the ILR-transformed series, the ILR-transformation of the compositional differenced series of order 1, and
Abstract in UndeterminedEdge sealing is often used to assure one-dimensional moisture flow and a defined exposure area in moisture transport experiments. This paper deals with the performance of a number of edge sealing systems including wax-paraffin mix, epoxy adhesive, silicone and different tapes and films. The overall performance of the sealing systems includes vapor permeability and hygroscop
In this paper we establish a geometry-based stochastic ultra-wideband channel model for outdoor infostations scenarios. We statistically describe the location and strength of clusters of scatterers, as well as the shape and width of visibility and shadowing regions. We also separately model diffuse radiation (which cannot be explained by the scatterer components), and show that its fading statisti
This study aims to provide a comprehensive overview of sustainability practices in food retailing sector. Report is structured to reflect on overall sustainability trends among European food retailers, outline drivers and barriers to address sustainability issues in retailer’s supply chain operations and provide classification of sustainability initiatives undertaken by EU retail organizations tha
Rediscovering Grounded Theory is a bold re-evaluation of the origins of grounded theory, a philosophical clarification of its key ideas and a presentation of the most effective way to use its techniques in your research. It answers questions such as 'What should grounded theory look like?', 'How do I recognise grounded theory?' and 'How do I produce good grounded theory?' by returning to the origi
Different opinions about Mongolian prominence structure can be found in the literature. The most puzzling problem is the nature of lexical stress in this language, and neither its placement nor its phonetic nature have been given any final description. We have earlier performed an acoustic investigation of vowel durations, quality and fO to find if any of these three parameters functions as signa
Managing credit risk might be the single most important business area for any commercial bank. The assessment of "good" and "bad" corporate clients is a important task for a creditor. A bad debtor is a corporate client with hardships in meeting the continous claims (interest payments) that a creditor requires. One way of evaluating or separating a "bad" client from a
This report deals with an evaluation study carried out on the community based accident prevention program being run by the municipal fire and rescue brigades in Landskrona and Svalöv. A major survey shows only a few results that could determine differences as statistically significant in fire safety behavior between the study group (inhabitants in Landskrona and Svalöv) and controll groups, but th
The purpose of this master’s thesis is to critically discuss blogs as a medium for dialogue based communication in a public relations context, and to empirically study how organizations and blogs perceive each other and how this affects the organization’s public relations practice. The research was partly conducted through qualitative interviews with communications professionals representing six m
The present study is included in a project with the aim to develop attractants from food odors for trapping female moths. Males and mated, but not unmated, females of Ephestia cautella and Plodia interpunctella were attracted by odors of three different chocolate products in flight tunnel experiments. Chocolate containing nut or rum elicited upwind flight and landing responses. Extracts of the cho
We used video-tracking of individuals of a Collembola, Protaphorura armata, on a clay surface in a petri dish to analyse their movement pattern in an environment with attractive and repellent cues. An area with dead conspecifics was repellent whilst live conspecifics made the area attractive. An area which had been occupied for 24 hours by the predatory mite, Hypoaspis aculeifer, was avoided only
Semiconductor nanowires of III-V materials have generated much interest in recent years. However, the growth mechanisms by which these structures form are not well understood. The so-called vapor-liquid-solid (VLS) mechanism has often been proposed for III-V systems, with a chemically inert, liquid metal particle (typically Au) acting as a physical catalyst. We assert here that An is, in fact, not
