“Reflections on a myth” : Reading text and image in a new perspective
- 2016
-
Konferensbidrag (refereegranskat)abstract
- Paragone is a well-known and often applied category to discuss the interrelationship of the Sister Arts. However, it does not seem to be a sufficient label to respond to the general questions raised about representation, mimesis and identity brought together in the postmodern intermedial writing of The Matisse Stories (1993), by A.S. Byatt, which was influenced by French avant-garde literature and visual arts. Therefore, I propose the integration of the reader as a third part by drawing on the peritextual design as well as on circumtextual and intratextual frames. Such an alternative allows me to anchor an emblematic tradition of perceiving the materialised form of the printed book that in postmodern rhetoric plays both with the interdependency of text-image and their contextual relationship along with the Sister Arts and their marginalised little brothers.

A weave of symbolic violence : Dominance and complicity in sociolinguistic research on multilingualism
- 2020
-
Ingår i: Multilingua - Journal of Cross-cultural and Interlanguage Communication. - Berlin : Mouton de Gruyter. - 0167-8507 .- 1613-3684. ; 39:4, s. 451-473

- This paper discusses symbolic violence in sociolinguistic research on multilingualism. It revisits an archived recording of a group discussion between four boys about their chances of having sex with a female researcher. The data is rife with symbolic violence. Most obviously, the conversation enacted a heterosexist form of symbolic violence. This was, however, not the only direction in which violence was exerted. As argued by (Bourdieu & Wacquant. 1992. An invitation to reflexive sociology. Cambridge: Polity), symbolic violence involves two fundamental elements – domination and complicity. In the case at hand, the boys’ sexist banter conformed to dominant expectations about their linguistic behavior, imbued in the research event. This is symbolic complicity of the kind that the Bourdieusian notion foresees. Yet another subordination to the dominant vision occurred when the researchers captured the conversation on tape, but decided to exempt it from publication. Here, we argue that giving deepened attention to sociolinguists’ own run-ins with symbolic violence during research is valuable, because it provides an opportunity to reflexively consider the social conditions of the research practices, in relation to the data produced and analyzed. Ultimately, this reflexive exercise may help sociolinguists sharpen their tools for understanding the give and take of dominance and complicity unfolding in their data.

Geographical Routing in Intermittently Connected Ad Hoc Networks
- 2008

Ingår i: The First IEEE International Workshop on Opportunistic Networking WON-08,2008. - : IEEE. - 9780769530963

Konferensbidrag (refereegranskat)abstract
- In intermittently connected ad hoc networks standard routing protocols like AODV, DSR and GPSR fail since they generally cannot find a contemporaneous path from source to destination. In this paper we present LAROD, a geographical routing protocol for intermittently connected networks. Combining beacon less geographical routing with store-carry-forward LAROD greedily searches for the shortest way to the destination and when no progress is possible packets are temporarily stored until node mobility has created a new path. In the paper we have shown by a comparative study that LAROD has almost as good delivery rate as an epidemic routing scheme, but at a substantially lower overhead.

Lightning Localization Based on VHF Broadband Interferometer Developed in Sri Lanka
- 2018
-
Ingår i: 2018 34th international conference on lightning protection (ICLP 2018). - New York : IEEE. - 9781538666357

Konferensbidrag (refereegranskat)abstract
- A basic broadband digital interferometer was developed, which is capable of locating Very High Frequency (VHF) radiation sources in two spatial dimensions and time. Three antennas sensed the time series of broadband electromagnetic (EM) signals and digitized with 4 ns sampling interval for a duration of several milliseconds. A technique based on cross-correlations has been implemented for mapping lightning source locations. A map of the first return stroke (RS) and the preceding stepped leader was mapped successfully, using the system with a time resolution of few milliseconds. The result was compared with the visible events of the ground flash to validate the system.

Ergonomics evaluation of modified industrial helmets for use in tropical environments
- 1988

Tidskriftsartikel (refereegranskat)abstract
- Hotness, weight, fitting problems etc., have been found to be the chief causes of the unpopularity of industrial safety helmets in tropical environments in developing countries (DC). Some selected safety helmets manufactured in industrialized countries (IC) were modified to provide extra head ventilation and to reduce weight, in order to make them more acceptable to users in hot environments. The modified helmets were subjected to ergonomics evaluation both objectively and subjectively in the laboratory (in simulated tropical conditions) as well as in the field situation. There was evidence that white helmets had some advantages in comfort, viz. reduction of hotness, compared to the other colours, e.g. red, green etc., when worn in the presence of radiant heat in the laboratory. Ventilation holes provided at the top of the shell seemed to reduce the greenhouse effect within the helmet shell which therefore felt less uncomfortable than a fully covered helmet. Even with a small reduction of weight, such as 45 g in helmets weighing about 350g, the difference in weight was perceived by the wearers. In adapting helmets made in IC for use in tropical climates, head ventilation and low weight perception are important aspects in comfort which need to be considered. In addition to low cost, a harness material suitable for sweat absorption is required. Adjustability and sizing to fit 90% of the user population also needs to be considered in the design and manufacture of safety helmets for people in DC.

Ergonomics aspects of personal protective devices

Konferensbidrag (refereegranskat)abstract
- The use of a personal protective device (ppd) is a widely accepted method of safeguarding workers from occupational hazards in industrialized countries (IC) and an important method employed in developing countries (DC). Though protection is assured if the devices are worn constantly, it is unfortunate that due to discomfort and inconvenience, the majority of those exposed to hazards do not wear them. DCs which mainly import ppds from ICs are confronting many ergonomics problems, because the equipment designed for IC conditions is inappropriate for use in DCs, due to significant differences in user body sizes, environments and working methods. A questionnaire survey conducted among ppd manufacturers in 11 ICs revealed that 90% followed standards in manufacturing. Another survey conducted among health and safety authorities who responded on behalf of ppd users in 35 DCs revealed that the most common ergonomic causes of non-use are stresses from hotness, weight, improper fit and obstruction at work. While manufacturers place greater emphasis in the protection performance of the equipment, users in DCs refuse to wear it because the comfort needs are not fulfilled. Developing ergonomics standards for ppds seems to be a feasible way of persuading the manufacturers to provide ergonomic values in ppds. The need for maximum allowable comfort in the design, taking into consideration the user characteristics and protection factor is emphasized. To overcome the inherent discomforts that are extremely difficult to reduce without compromising the protection efficiency of a ppd, the principle of user adaptation seems to be a very important facet which has to be developed. A case study on safety helmets is reported.

Human factors of clothing and work-wear : a review
- 1994
-
Ingår i: Proceedings. - Kiel : German Society of Physiological Anthropology. ; , s. 137-142
-
Konferensbidrag (refereegranskat)abstract
- An extraordinarily large share of research carried out in the near past on clothing comfort has been in the area of thermal comfort. Accordingly standards, norms and guidelines on thermal requirements of work-wear have been developed. Through behavioural adjustments people have learned to achieve thermal comfort even if the work clothes have slight deficiencies in thermal characteristics. It is beyond doubt that the thermal characteristics need careful consideration in the manufacture of work clothes. At the same time one must be aware that other human factors can also influence the overall wearability of clothing. This paper reviews the wearability and comfort of the clothing and work-wear to provide better understanding of the priorities in user needs in work clothes which can help plan future research and the need for new standards

Charged Kaon Interferometric Probes of Space-Time Evolution in Au plus Au Collisions at s(NN)=200 GeV
- 2009

Ingår i: Physical Review Letters. - 1079-7114. ; 103:14

Tidskriftsartikel (refereegranskat)abstract
- Bose-Einstein correlations of charged kaons are used to probe Au+Au collisions at s(NN)=200 GeV and are compared to charged pion probes, which have a larger hadronic scattering cross section. Three-dimensional Gaussian source radii are extracted, along with a one-dimensional kaon emission source function. The centrality dependences of the three Gaussian radii are well described by a single linear function of N-part(1/3) with a zero intercept. Imaging analysis shows a deviation from a Gaussian tail at r greater than or similar to 10 fm, although the bulk emission at lower radius is well described by a Gaussian. The presence of a non-Gaussian tail in the kaon source reaffirms that the particle emission region in a heavy-ion collision is extended, and that similar measurements with pions are not solely due to the decay of long-lived resonances.
