- Invasive disease caused by antibiotic resistant pneumococci is a worldwide problem. All invasive pneumococcal strains in an area of south-west Sweden with 1.7 million inhabitants were collected prospectively during 1998-2001. Minimum inhibitory concentrations (MICs) were determined by E-test and correlated to serotypes and clinical characteristics. Of 827 strains, 744 (90%) were susceptible (S) to all agents tested and 83 (10%) were indeterminate (I) or resistant (R) to at least 1 agent. 22 isolates (2.7%) were I to penicillin (MIC >0.06 to < or = 1.0 mg/l), but none were R (MIC >1.0 mg/l). Numbers and proportions of decreased susceptibility against other agents tested were as follows: erythromycin R: 30 (3.6%), clindamycin R: 6 (0.7%), tetracycline R: 16 (1.9%), moxifloxacin R: 1 (0.1%), cotrimoxazole I: 17 (2%) and R: 31(4%). Non-susceptibility to at least 1 agent was not correlated with age, clinical manifestation, underlying diseases and outcome. The serotype distribution differed between non-susceptible and susceptible strains. The serotypes in the 7-valent pneumococcal conjugate vaccine covered 42% of all infections and 73% of those caused by non-susceptible strains. In conclusion, the impact of antibiotic resistance in invasive pneumococcal disease remains limited in south-west Sweden.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- This article relates computer gaming to the social psychology of identity, focusing the notion that identity construction has a reflected character not only in virtual reality but also in real life. This gives a tight correspondence between the two, although the screen construction of identity goes on in greater independence of real other persons. Gaming has the trait that it contracts several events at one point in space and time. This provides for two extremes of identification: functional and existential identification, which are tightly coupled in gaming, but also for the element of meaning creation in gaming, where the step from concrete action to mental act is short, as well as for the processes of anticipatory identification that are found in it. This gives a high emotional intensity to it. The analysis is based on a theoretical sketch of stages in the act, building on the work of G. H. Mead.

Tidskriftsartikel (refereegranskat)abstract
- The aim of this text is to introduce perspectives, questions and empirical examples regarding children's identity construction in play with dolls and figures that represent women and men in both gender-typed and non gender-typed ways. Videotaped play of two 4-year old boys and three 5-year-old girls in a preschool setting is analyzed from complementary interactionistic and socio-cultural perspectives. The level of plasticity in the toyplay is interpreted. The results suggest ways in wich the gender-plastic character of toy play can be founded in children's intentions as well as in the toys' character as mediating tools. The analysis is based on whether children play with, through, in or beside their toy gestalts. These and other similar distinctions help to differentiate identity consequences in play.

- Denna text handlar om lek med leksaker som traditionellt varit exkluderade i svensk förskola, t.ex. Barbie och Action Man. Förskolan präglas av värden som står i motsättning till de «genusifierade» värden som förknippas med dessa och liknande leksaker (Almqvist, 1994; Fredricson, 2003). Samtidigt är förskolan en del av samhället med dess stereotypa genusrepresentationer

- The lowest-lying radiative state of barium chloride has been studied by laser-induced fluorescence in the near-infrared wavelength region. The A (II1/2)-I-2 and A (II3/2)-I-2 states have been investigated in time-resolved experiments using a Ti:Sapphire laser. The zero pressure radiative lifetime measured for the e-levels of BaCl was 107 +/- 4 ns for the A (II1/2)-I-2 state and 101+/-6 ns for the A (II3/2)-I-2 state. The discrepancy between the corresponding transition moments is discussed.

Tidskriftsartikel (refereegranskat)abstract
- We present experimental results for the cross phase modulation (xpm) induced transient absorption signal in a 1 mm thick fused silica plate using a white light continuum as a probe. The fused silica plate mimics the entrance window of a commercial flow cell commonly used in liquid-phase transient absorption measurements. The experimental results are compared with those obtained theoretically by numerically solving the set of nonlinear coupled wave equations describing the propagation of the pump and the probe. The simulations allow for the different group velocities of the pump and probe pulses, and include the influence of the first and second order dispersion on the continuum probe. From the calculations the physical origin of the complex oscillatory feature observed around the zero time delay of each wavelength of the (chirped) continuum has been accurately identified. The influence of propagation effects arising from the finite thickness of the sample is discussed in great detail, and the necessity to work with thin samples, preferably free-flowing jets, is emphasized. The good agreement between theory and experiment indicates that the xpm artifact may be useful for characterizing the continuum probe, in particular its chirp.

A theory of the emotional self : from the standpoint of a neo-Meadian
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this dissertation, two fundamental questions are posed: (1) what is emotion, and (2) what part does it play in the social processes of self-formation and self-realization? How do we as behaving beings, who experience sensations, become interacting beings, who experience emotions? And, how are our emotional experiences related to who we are and our ability to acquire a positive relation to ourselves? By attempting to answer these questions I point out the social conditions that are necessary to enable emotional experiences, and in turn self-formation and self-realization. The focus is on the form, rather than on the content of the emotional self. From the developed neo-Meadian perspective on the emotional self, emotion is understood as a phenomenon linked to both mind and body, without being explained as a mind-body combination. It is argued that emotional experiences are (1) corporal evaluations of our interchanges with the outer world, especially, the other, and (2) crucial to who we are or want to be. An introduction to the neo-Meadian theory of the emotional self is presented in a general manner by including notions of the social self and emotion as social. In the first part of the dissertation, I suggest that diverse phenomena in the social process of self-formation and self-realization is explained by a view that has its roots in the classic social psychology of Adam Smith, Charles Horton Cooley, and, especially, George Herbert Mead. The view consists of three salient ideas: (1) the self does not emerge without the other or society, (2) it is from the point of view of the other or society that the self develops, and (3) self-realization involves a need for recognition. In the second part of the dissertation, I expand the view on emotion as social that is incorporated in the classic social psychology by investigating the recently established field of the sociology of emotions. Once the general structure of the notion of the social self and emotion as social is shown and provided with a preliminary defense, different modifications are considered. In the third part of the dissertation, both the classic social psychology and the sociology of emotions are modified to become more accurate. I elaborate on Mead’s distinction between social behavior, in the form of (1) functional identification, and social interaction, in form of (2) attitude taking of the thing from which he means that self-feeling arises, and (3) attitude taking of the other from which he means that self-reflexion arises.

Tidskriftsartikel (refereegranskat)abstract
- The resonance ionization laser ion source (RILIS) at the ISOLDE on-line isotope separator is based on the selective excitation of atomic transitions by tunable laser radiation. New ion beams have been produced with RILIS in recent years: Sb, Sc, Dy, Au, Hg and Po. In total, isotopes of 26 different elements have been selectively laser-ionized and separated at ISOLDE. In order to facilitate the work on development of atomic ionization schemes an off-line laser laboratory has been established at CERN. Operating independently of the on-line RI LIS setup, this laboratory will be capable of providing extensive data on atomic transitions, in particular between highly excited and auto-ionizing atomic states, which are required for the improvement of the RILIS efficiency. Additionally, the program gram of upgrading the on-line RI LIS system by the implementation of solid state lasers will be presented.

- Forty participants fulfilling the DSM-IV criteria for dental phobia were randomly assigned to a waitlist group, one-session or five-session exposure treatment. Assessment occurred pre-, post-waitlist/treatment, and after 1 year. Mean avoidance of dental care before treatment was 11.4 years. A total of 77% sought dental care in the follow-up year. Both treatments were equally effective at reducing avoidance behavior and changing cognitions during the feared situation. Post-treatment, the five-session group scored lower on the dental anxiety scales, but at follow-up, both groups reported the same level of dental anxiety. Conclusion: Both treatment conditions enable a return to ordinary dental treatment.

- Experimental and early clinical investigations have demonstrated encouraging results for estramustine in the treatment of malignant glioma. The present study is an open randomized clinical trial comparing estramustine phosphate (Estracyt) in addition to radiotherapy with radiotherapy alone as first line treatment of astrocytoma grade III and IV. The 140 patients included were in a good clinical condition with a median age of 55 years (range 22-87). Estramustine was given orally, 280 mg twice daily, as soon as the diagnosis was established, during and after the radiotherapy for a period of in total 3 months. Radiotherapy was delivered on weekdays 2 Gy daily up to 56 Gy. Eighteen patients were excluded due to misclassification, leaving 122 patients eligible for evaluation. Overall the treatment was well tolerated. Mild or moderate nausea was the most common side effect of estramustine. The minimum follow-up time was 5.2 years for the surviving patients. For astrocytoma grade III the median survival time was 10.6 (1.3-92.7) months for the radiotherapy only group and 17.3 (0.4-96.9+) months for the estramustine + radiotherapy group. In grade IV the corresponding median survival time was 12.3 (2.1-89.2) and 10.3 (0.3-91.7+) months, respectively. Median time to progress for radiotherapy only and radiotherapy and estramustin group in grade III tumours was 6.5 and 10.1 months, respectively. In grade IV tumours the corresponding figures were 5.1 and 3.3 months, respectively. Although there was a tendency for improved survival in grade III, no statistical significant differences were found between the treatment groups. No differences between the two treatment groups were evident with respect to quality of life according to the EORTC QLQ-protocol. In conclusion, this first randomized study did not demonstrate any significant improvement of using estramustine in addition to conventional radiotherapy, however, a trend for a positive response for the estramustine group was found in patients with grade III glioma.

Resonant multi-photon ionisation studies of high-energy states in small molecules
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis describes separate studies of high-energy Rydberg and ion-pair states in small molecules using resonant multi-photon ionisation spectroscopy. * OODR/REMPI study of ungerade Rydberg states in O2 The energy region between 75000 and 99900 cm-1 of O2 has been studied using optical-optical double resonance (OODR) with resonance enhanced multi-photon ionisation (REMPI). Three-photon excitation via single rotational levels of the b(1Σ+g ) valence state was used to study np (n=3–10) and nf (n=4–9) Rydberg states converging on O2+X(2Π1/2,g) and X(2Π3/2,g). The excitation pathway picks out non-predissociated states that are singlet in the (Λ,S) coupling scheme – suitable for np states for n ≥8, or are linear combinations of equal weight of singlet and triplet-spin states in the (Ω,ω) coupling scheme which was found to be suitable for nf states for all values of n. * OTR/RI study of Rydberg and ion-pair states in I2 Optical triple resonance (OTR) together with resonance ionisation (RI) has been used to study the ungerade manifold of molecular iodine between 57000 and 73000 cm-1 via the E 0g+(3P2) ion-pair state. Two 6s Rydberg states with 0 +u symmetry based on excited states of the ion core have been observed. During this study we also observed electric-field-induced mixing of nearly isoenergetic rovibrational levels of the E0gP+(3P2) and D0u+(3P2) ion-pair states. Detectable mixing with an applied field of 1kV/cm occurs over a range of energy level separations of ≤0.3 cm-1. * (2+1)and (3+1) REMPI study of pyrrole (C4H5N) The two- and three-photon REMPI spectra of Rydberg states of pyrrole (C4H5N) have been recorded using circularly and linearly polarised light. The spectra were compared to the single-photon absorption spectrum of pyrrole and a similar study of furan (C4H4O). Although the ionisation spectra of pyrrole were considerably weaker than corresponding furan spectra, a strong propensity for excitation of d series with two photons and p and f series with three photons was observed for both molecules. The totally symmetric nd-Rydberg series associated with the first ionisation energy, [A2]nd;A1, was identified from n=3 to n=15 and extrapolated to obtain IE1.

Tidskriftsartikel (refereegranskat)abstract
- The atomic emission of laser-induced plasma on steel samples has been studied for quantitative elemental analysis. The plasma has been created with 8 ns wide pulses using the second-harmonic from a Q-switched Nd:YAG laser, in air at atmospheric pressure. The plasma emission is detected with temporal resolution, using an Echelle spectrometer of wide spectral range (300-900 nm) combined with an intensified charge coupled device camera. A plasma temperature of 7800 400 K is determined using the Boltzmann plot method, from spectra obtained under optimized experimental conditions. As an example of an industrial application the concentration of copper in scrap metals is studied, which is an important factor to determine the quality of the samples to recycle. Cu concentrations down to 200 ppm can be detected. Another application of the laser-induced plasma spectroscopy method is the measurement of the nickel and copper concentrations in an iron-containing sample of reduced magma from the 1870s expedition to western Greenland by Adolf Erik Nordenskiold. Different spectral lines of nickel are used for calibration, and their results are compared.

S(t)imulating a Social Psychology : G. H. Mead and the Reality of the Social Object
- 2003
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Social psychology is often said to be a scientific discipline aiming at the observation and explanation of actions between human beings or, more generally, between the human individual and the environment. This general proposition holds for most social psychologists, irrespective of allegiance. Accepting this, it is implied that we are observing the social aspect of a human individual. This text will ask for the conditions under which this social psychology is possible. Indeed, what has to be the case for the observation and explanation of the sociality of the individual to occur?On the basis of G. H. Mead, generally considered the hub around which modern social psychology developed, it will be argued that for a social psychological science to be possible, conditions are implied that make it impossible. Less rhetorically put, accepting or returning to Meads social argument and trying to co-ordinate it with basic premises of scientific conduct, one will find oneself caught between two Meadian facts. On the one hand each individual must be considered social, i.e., appearing to experience as two objects at once. On the other hand, however, explaining an object is to state the object in an unambiguous fashion, i.e., as an independent, hence individual, object. It will be argued here that Mead’s epistemology does not support a scientific and social psychology. Rather a scientific social psychology based on Mead constitutes a contradiction in terms, stemming from a series of misinterpretations. It is the objective of this text to demonstrate these misinterpretations with respect to attempts at a scientific social psychology based on the social vision of this scholar.

Wavepacket dynamics and predissociation of the D-1 Pi(u) state of Rb-2
- 2000

Tidskriftsartikel (refereegranskat)abstract
- We present the first experimental investigation of the real-time dynamics of predissociation in a diatomic molecule involving more than two electronic states - the predissociation of the D(1)Pi(u) state of Rb-2. Our results show that the state is strongly predissociated, tau approximate to 5 ps, above a sharp energy threshold. We propose that mainly the (1)(3)Delta(u) state causes the fast predissociation and that the fine-structure components of the products are mixed by coupling among molecular states at large internuclear distances. Furthermore, an outward-inward asymmetry of the wavepacket signal is attributed to autoionisation of the wavepacket evolving in the probe (Rydberg) state.
