Looking for representative fit models for apparel sizing
2014
This paper is concerned with the generation of optimal fit models for use in apparel design. Representative fit models or prototypes are important for defining a meaningful sizing system. However, there is no agreement among apparel manufacturers and each one has their own prototypes and size charts i.e. there is a lack of standard sizes in garments from different apparel manufacturers. We propose two algorithms based on a new hierarchical partitioning around medoids clustering method originally developed for gene expression data. We are concerned with a different application; therefore, the dissimilarity between the objects has to be different and must be designed to deal with anthropometr…
Physical Activity and Exercise: Text Mining Analysis
2021
It is currently difficult to have a global state of the art vision of certain scientific topics. In the field of physical activity (PA) and exercise, this is due to information overload. The present study aims to provide a solution by analysing a large mass of scientific articles using text mining (TM). The purpose was to analyse what is being investigated in the PA health field on young people from primary, secondary and higher education. Titles and abstracts published in the Web of Science (WOS) database were analysed using TM on 24 November 2020, and after removing duplicates, 85,368 remained. The results show 9960 (unique) words and the most frequently used bi-grams and tri-grams. A co-…
Study Crafting and Self-Undermining in Higher Education Students: A Weekly Diary Study on the Antecedents.
2021
The aim of the current study is to validate the adaptation of the job demands–resources theory to the study context. In addition, we introduce the concepts study crafting and self-undermining to the study demands–resources framework by examining the mediating role of engagement and exhaustion in the relationship between study characteristics and study crafting and self-undermining. Over four consecutive weeks, 205 higher education students answered a questionnaire about their weekly study demands and resources, their well-being (i.e., engagement, exhaustion), and their study crafting and self-undermining behaviors. Multilevel structural equation modeling (controlling for autoregressors of m…
ComPWA: A common amplitude analysis framework for PANDA
2014
A large part of the physics program of the PANDA experiment at FAIR deals with the search for new conventional and exotic hadronic states like e.g. hybrids and glueballs. For many analyses PANDA will need an amplitude analysis, e.g. a partial wave analysis (PWA), to identify possible candidates and for the classification of known states. Therefore, a new, agile and efficient amplitude analysis framework ComPWA is under development. It is modularized to provide easy extension with models and formalisms as well as fitting of multiple datasets, even from different experiments. Experience from existing PWA programs was used to fix the requirements of the framework and to prevent it from restric…
GOLD MINING AND JULA INFLUENCE IN PRECOLONIAL SOUTHERN BURKINA FASO
2007
ABSTRACTThe ‘Lobi’ region in what is today southern Burkina Faso is frequently mentioned in historical accounts of gold mining in West Africa. However, little is known about the actual location of the gold mines or about the way gold mining and trade were organized in precolonial times. This article points out that some previous hypotheses about precolonial gold mining, trade and the sociopolitical organization of this region are flawed, partly because ‘Lobi’, as the name for both the region and its inhabitants, is misleading. In fact, the references to ‘Lobi’ merge two distinct gold-producing zones along the Mouhoun river, about 200 km from each other. The present-day populations of southe…
The poor man’s goldmine? : Career paths in Swedish and Finnish merchant shipping, c. 1840–1950
2017
This article analyses the career paths of Swedish and Finnish sailors from the mid-19th to the mid-20th century. The article shows that, for the most of the men, the seaman’s occupation was just a passing phase before taking up a job on shore, but many of them also created a longlasting and advancing career by going to sea. There was not necessarily, however, a clear distinction between job opportunities at sea and those on shore in those days: men worked both at sea and on shore. We therefore argue that an individual’s advancement in a maritime career was a context-specific socio-economic phenomenon. In Scandinavia, work on board ships was dependent on features that characterized the divis…
The Lure of Katanga Copper : Tanganyika Concessions Limited and the Anatomy of Mining and Mine Exploration 1899–1906
2016
This article provides a rare opportunity to follow the inception of mining and mine exploration economy in the first years of the European presence in colonial Zambia and Katanga as seen through the eyes of prospectors and mining experts working for the London-based company Tanganyika Concessions Limited. It draws on company records as well as the personal records of the early company employees who worked in North Western Rhodesia and adjoining Katanga until 1906. The most thought-provoking documents include diaries, letters and photographs, which depict the organisation and processes of early mining work, modes of mine exploration, and relations within the first mining communities and betw…
Identification of New Genetic Clusters in Glioblastoma Multiforme: EGFR Status and ADD3 Losses Influence Prognosis
2020
Glioblastoma multiforme (GB) is one of the most aggressive tumors. Despite continuous efforts to improve its clinical management, there is still no strategy to avoid a rapid and fatal outcome. EGFR amplification is the most characteristic alteration of these tumors. Although effective therapy against it has not yet been found in GB, it may be central to classifying patients. We investigated somatic-copy number alterations (SCNA) by multiplex ligation-dependent probe amplification in a series of 137 GB, together with the detection of EGFRvIII and FISH analysis for EGFR amplification. Publicly available data from 604 patients were used as a validation cohort. We found statistical associations…
Mining travel patterns from mobile ticket applications
2014
Masteroppgave i Informasjons- og kommunikasjonsteknologi IKT590 Universitetet i Agder 2014 Customers’ travel patterns are highly interesting for transportation companies due tothe insight it gives over the use for their services. Logs of the customers’ location datais an important source for such companies. However, such data is not collected and isprivately owned by the individual customers. To find the customers’ travel patterns,their location data requires to match a coded map of transportation network.This paper introduces a novel solution that automatically collects location and timedata from the customers without the need for the customers to actively submit thedata. This paper presen…
Post-translational modifications in the survival motor neuron protein
2004
Spinal muscular atrophy (SMA) is an autosomal recessive disease characterized by a progressive loss of the spinal motoneurons. The SMA-determining gene has been termed survival motor neuron (SMN) and is deleted or mutated in over 98% of patients. The encoded gene product is a protein expressed as different isoforms. In particular, we showed that the rat SMN cDNA produces two isoforms with Mr of 32 and 35 kDa, both localized in nuclear coiled bodies, but the 32 kDa form is also cytoplasmic, whereas the 35 kDa form is also microsomal. To determine the molecular relationship between these two isoforms and potential post-translational modifications, we performed transfection experiments with a …
