Forskningsöversikt (refereegranskat)abstract
- ALICE (A Large Ion Collider Experiment) is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model. It is designed to address the physics of strongly interacting matter and the quark-gluon plasma at extreme values of energy density and temperature in nucleus-nucleus collisions. Besides running with Pb ions, the physics programme includes collisions with lighter ions, lower energy running and dedicated proton-nucleus runs. ALICE will also take data with proton beams at the top LHC energy to collect reference data for the heavy-ion programme and to address several QCD topics for which ALICE is complementary to the other LHC detectors. The ALICE detector has been built by a collaboration including currently over 1000 physicists and engineers from 105 Institutes in 30 countries, Its overall dimensions are 16 x 16 x 26 m(3) with a total weight of approximately 10 000 t. The experiment consists of 18 different detector systems each with its own specific technology choice and design constraints, driven both by the physics requirements and the experimental conditions expected at LHC. The most stringent design constraint is to cope with the extreme particle multiplicity anticipated in central Pb-Pb collisions. The different subsystems were optimized to provide high-momentum resolution as well as excellent Particle Identification (PID) over a broad range in momentum, up to the highest multiplicities predicted for LHC. This will allow for comprehensive studies of hadrons, electrons, muons, and photons produced in the collision of heavy nuclei. Most detector systems are scheduled to be installed and ready for data taking by mid-2008 when the LHC is scheduled to start operation, with the exception of parts of the Photon Spectrometer (PHOS), Transition Radiation Detector (TRD) and Electro Magnetic Calorimeter (EMCal). These detectors will be completed for the high-luminosity ion run expected in 2010. This paper describes in detail the detector components as installed for the first data taking in the summer of 2008.

Scuba Diving and the "Right Attitude"

Tidskriftsartikel (refereegranskat)abstract
- Based on ethnographic fieldwork on scuba diving, this article explores the social homogeneity characterizing this specific leisure activity regarding questions on how deviance is treated within a group and on what grounds. The consequences of the dangerous context in which the activity is performed on the dyad (one is always diving with a “Buddy”) is analysed with the help of Georg Simmel (1950) and Erving Goffman (1967). The loyalty of the diving companion (the buddy) towards the “right attitude” which governs the activity may be turned against the scuba diver who does not adapt. The buddy is transformed from a friend into an opponent, who, by spreading anecdotes or rumours, questions the character of the scuba diver, which eventually may exclude him or her from the activity. The article also discusses how the “right attitude” in scuba diving is related to the so-called predominant masculine identity (Connell 1995) in a Swedish context.

- The Scuba Diver and “Proper” MasculinityBased on ethnographic fieldwork on scuba diving, this article explores the social homogeneity characterizing this specific sport activity regarding questions on how deviance is treated within a group and on what grounds.

Recension (övrigt vetenskapligt/konstnärligt)abstract
- A limited part of sport studies concerns itself with a limited part of sports, viz. the so-called extreme sports. One might expect these modern expressions of the need for physical activity and perilous adventures would generate more interest from sport sociologists and psychologist than is witnessed by the body of publications in the area. It’s reasonable to suggest that studies of phenomena outside the norm, beyond mainstream, is valuable not only for what is reveals of those phenomena, but just as much for what it tells us about the normal, the everyday life most of us live. An illustrative example of this is a new book by Victoria Robinson, established and productive sociologist in the field of gender studies at Sheffield University. The book, with the working title “A Different Kind of Hard: Everyday Masculinities, Identity and Rock Climbing”, was published by Berg Publishers in 2008 without the obvious innuendo as Everyday Masculinities and Extreme Sport: Male Identity and Rock Climbing. Robinsons book, reviewed here by Dr. Åke Nilsén, also a sociologist and researcher in the field of extreme sports, is a study of male climbers and the construction of their masculinity in relation to the everyday male identity. Our reviewer would have liked a macro level analysis, but he is on the whole very positive to Robinson’s effort.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Based on an ethnographic fieldwork this paper explores the relation between technology and masculinity in the context of scuba diving. From a theoretical framework based on Heidegger/Kemp and Wajcman, two major questions are put to the material: How is technology influencing social relations and communication? And: How is technology perceived and handled? The first question is answered out of two angels: Judging performance out of handling the equipment and forming the social hierarchy. The second question is answered: out of a practical knowledge, through embodiment and trust.
