Two experimental studies in foreign language learning/teaching
- 1982
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The case for experimental research on the efficiency of methods of foreign language teaching is pleaded. In the first study, the effects of different practice materials on beginners' word-decoding ability in Russian was examined. The Russian words were divided into three categories: 1. The KTO-type. These words are in conflict with Swedish phonotactic rules and their meaning is not evident to a Swedish beginner. 2. The MAKET-type These words are phonotactically non-contrastive. To a Swedish learner, they are semantically opaque, however. 3. The ATOM-type. These words are also phonotactically non-contrastive and their meaning is potentially transparent to the Swedish beginner. Three groups of subjects were formed — each group practising on one and only one of the word-types. All subjects were then given a decoding test on all three types. No significant differences between groups were found, but there was significant interaction to the effect that the group that had practised on the more difficult KTO-type of words was better at decoding that type than the other groups. This group got the decoding of the MAKET and ATOM types into the bargain. Thus, in this case, progression need not be ' from the simple to the difficult ". In fact, it seems preferable to start with the more difficult words In the second experiment, two different ways of learning vocabulary in a foreign language (English) were compared, viz. concept learning in 11 with subsequent memorization of the L2 labels vs. concept learning in L2 with subsequent memorization of the L1 labels. The concepts and vocabulary of heraldry were used. With a group of university students of English, the English labels were learned more efficiently in the L2 concept learning case. With a group of 17-year-old high-school pupils, however, the results were inconclusive. It is suggested that the outcome in the latter case is due to language (LI) preference in connection with, or rather than, poorer foreign language proficiency The results indicate, then, that concept learning as a means to foreign language vocabulary acquisition will be effective in many cases, where the learning situation is comparable to the present experimental situation: i.e. where it is possible to combine the learning of L2 with the acquisition of new knowledge about the world. The L2 proficiency and language preferences of the learners must be taken into account, however

- A YBa2Cu3O7- (YBCO) thin film is patterned into a hexagonal close packed lattice of disks which are touching each other at the circumferences in order to enable the flow of an intergranular current. Such a sample was suggested by Koblischka et al. [Appl. Phys. Lett 70, 514 (1997)] as a model for a layered granular structure like in a Bi2Sr2Ca2Cu3O10- tape. Magnetization measurements reveal an anomalous position of the low field peak (central peak) similar to the tapes. Magneto-optic imaging is employed to visualize the local field distributions

En studie av arbetsmiljön vid deponigasutvinning, sortering av avfall och hantering av miljöfarligt avfall
- 1992
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I projektet har arbetsmiljön vid deponigasutvinning, sortering av avfall och hantering av miljöfarligt avfall studerats. Arbetsmiljön vid deponigasanläggingar har studerats. I fläktstationer och panncentraler finns varnare som larmar vid höga metanhalter. Exponering för höga deponigashalter finns ej uppe på upplaget eftersom gasen snabbt späds ut i luften. Däremot finns risk för gasansamling i slutna utrymmen som gasbrunnar och lakvattenbrunnar. Höga metanhalter och låga syrehalter uppmättes vid flera tillfällen i en lakvattenbrunn under pågående försök med bioceller. I rapporten föreslås åtgärder för att öka den personliga säkerheten vid allt arbete i slutna utrymmen samt vid arbete på cellförsöksområden. Vid maskinell och manuell sortering av avfall kan organiskt damm, innehållande mikroorganismer och deras nedbrytningsprodukter (t ex endostoxiner), bildas i hälsofarliga mängder. De högsta dammhalterna mättes vid tippning av avfall i mottagningsbunkern eller lossningsplattan. Vid två sorteringsanläggningar uppmättes endotoxinhalter som överskred de rekommenderade riktvärdena för endotoxiner. För säker hantering av miljöfarligt avfall betonas vikten av välfungerande rutiner för kontroll av inkommande avfall. Det är viktigt att företag utarbetar hanteringsföreskrifter för speciellt riskfyllda arbeten. Underlag för framtagning av dessa föreskrifter finns i rapporten. I projektet sammanställdes och bearbetades de arbetsolyckor och arbetsskador som inträffat vid avfallsupplag och som finns registrerade i ISA. En ökning av arbetsskadefrekvensen för hela branschen har observerats de senaste åren (1986-1990). Stukning och vrickning är vanligt förekommade skadetyper bland de anmälda olycksfallen. Belastningsrelaterade sjukdomar dominerade bland de registrerade arbetssjukdomarna.

Forskningsöversikt (refereegranskat)abstract
- Variations in definitions and methodologies have created differences in the results and conclusions obtained from studies of football injuries, this has made inter-study comparisons difficult. An Injury Consensus Group was established under the auspices of FIFA Medical Assessment and Research Centre. Using a nominal group consensus model approach, a working document that identified the key issues related to definitions, methodology and implementation was discussed by members of the group during a 2-day meeting. Following this meeting, iterative draft statements were prepared and circulated to members of the group for comment before the final consensus statement was produced. Definitions of injury, recurrent injury, severity and training and match exposures in football together with criteria for classifying injuries in terms of location, type, diagnosis and causation are proposed. Proforma for recording players' baseline information, injuries and training and match exposures are presented. Recommendations are made on how the incidence of match and training injuries should be reported and a checklist of issues and information that should be included in published reports of studies of football injuries is presented. The definitions and methodology proposed in the consensus statement will ensure that consistent and comparable results will be obtained from studies of football injuries.

Tidskriftsartikel (refereegranskat)abstract
- Nicotinic acid is crystallized by adding hydrochloric acid (HCl) to a sodium nicotinate aqueous solution. An attenuated total reflection Fourier transform infrared spectrometer is used to monitor the crystallization process of nicotinic acid. The partial least squares method is employed for IR data analysis. The solubility of nicotinic acid varies with the pH and the concentration of sodium nicotinate. The ability to measure the concentration and solubility of nicotinic acid in situ in aqueous mixtures of nicotinic acid and sodium nicotinate provides the possibility of controlling the degree of supersaturation of the solution and in turn optimizing the crystallization conditions for nicotinic acid.Nicotinic acid is crystallized by adding hydrochloric acid (HCl) to a sodium nicotinate aqueous solution.

On Road Network Utility Based on Risk-Aware Link Choice
- 2013

Ingår i: International IEEE Conference on Intelligent Transportation Systems.

Konferensbidrag (refereegranskat)abstract
- We have previously shown how it is possible to lower accident risk levels while at the same time increasing traffic flows with the aid of vehicular ad-hoc networks. In this paper, we extend the online traffic accident risk mitigation sys- tem to include link choice. We develop an algorithm that allows vehicles to choose road links that provide the current maximal utility, based on information received over a vehicular network, whilst remaining below acceptable risk levels. Additionally, we investigate how to improve the performance of this algorithm by considering the effect a vehicle’s link choice has on the utility of other vehicles. We introduce a social penalty for reducing other vehicles’ utility and investigate the effects of including this as a factor in vehicles’ link choices. The resulting system sheds new light on the problem of effective link choice by route selection algorithms and highlights the potential that exists in VANET-based traffic management.

Tidskriftsartikel (refereegranskat)abstract
- Two human genes containing Notl sites, ADP-ribosylation factor (ARF2) and melanoma NCK protein, were mapped by fluorescence in situ hybridization to 3p21.2→ p21.1 and 3q21, respectively. Thirteen other <i>Not</i>I linking clones, representing sequence tagged sites, were also mapped to different regions of human chromosome 3. Two of these clones that contain sequences 80% homologous to the rat tropoelastin gene and brain Cl<sup>–</sup> channel protein CLC-2 gene probably represent new human genes closely related to the known rat genes.
