Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Cognitive training might have potential to improve speech understanding under adverse listening conditions. Here, we have examined the effects of a 5-week computer-based cognitive training program on speech-in-noise-performance, in normal hearing (NH) participants and in participants with mild-to-moderate sensorineural hearing loss (HI).Two groups, matched on gender and age (45-65 years), of 20 participants each (HI and NH respectively) are recruited. Participants perform four test-sessions; inclusion (t0), five weeks (t1), ten weeks (t2) and six months (t3). Training is performed either between t0 and t1, or between t1 and t2 (using a cross-over design), using the computer-based Cogmed training program, approximately 30-40 minutes per day, five days per week, during five weeks. At each session participants are tested in three different ways: (a) cognitive testing (KIPS, SICSPAN, TRT); (b) auditory performance (pure tone-audiometry (air- and bone-conduction) and speech audiometry (HINT, Swedish SPIN-test (SNR +4dB))); (c) cortical activation (MR sessions where participants performed a speech-in-noise task using Hagerman-sentences with steady-state speech-spectrum noise (SSN) and with two competing talkers). MR imaging is performed on a Philips Achieva 1.5 Tesla scanner using a sparse imaging technique in which stimuli are presented during the silent period between successive scans. Participants listen to auditory stimuli under eight different conditions: clear speech, SSN or two competing talkers (each at 90%, 50% and 0% intelligibility), and silent rest. Pre- and post-training, hearing disability is assessed by the Speech-Spatial-Qualities-Questionnaire.The study is on-going and behavioral results as well as results from fMRI will be presented.

Decentralization and centralization policies in education in Europe : current trends and challenges
- 2002
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Decentralization and centralization are as opposite trends in educational policies, as much as they are in economics and politics. A preliminary assumption considers the existence at European level of two main forces having a major impact in educational policies. First: the ideal of a common European identity, an economical and social community, which claims for common goals, unified policies, that is centralization. The second group of forces can be related to the importance of the individual and local level to be involved in decision making in education, the diminishing of the role of central authorities and the partnership market & education. This, on the contrary, is assumed to claim for decentralization in educational policies.With the above as a conceptual point of departure the First International Workshop attempted to initiate a debate and search for answers to questions such as the followings: In which ways this apparently “opposite forces” could strive towards the same goals?, Which criticism could be put forward to the approach presented above? Are there other perspectives to consider when scrutinizing decentralization and centralization in education? What is possible to do in terms of research to approach this problematic? The keynote speeches and papers included in this report approach some of these questions or deepen into others relevant with a perspective covering from research experiences to local issues.

- Purpose: We intended to assess consequences of reduced visual acuity for performance in a natural simple motor task (tracing) using objective kinematic performance measures. Specifically, we intended to elucidate the kind of relationship between the task performance and best corrected binocular visual acuity and to determine the threshold of visual acuity when task performance starts to deteriorate.Methods: Ninety-five individuals with different best corrected visual acuity participated in the study (age 49±12 years, mean±SD, 27 men and 68 women). The participants manually traced maze-like visual patterns of different spatial complexity presented on the screen of a portable notebook computer using Clinical Kinematic Assessment Tool software. Tracing error was computed as performance measure in each trial with a spatial pattern matching technique - rigid point set registration method.Results: The segmented linear regression analysis showed that the relation between visual acuity and tracing errors was best described with a regression function having a break point between two data segments. Tracing performance was unaffected by values of visual acuity below 0.2 on logMAR scale, but when logMAR values increased above this critical limit (i.e. when visual acuity is further reduced), tracing errors linearly increased. The rate of the increase of the tracing error correlated with the complexity of visual stimulus shape.Conclusion: Testing of fine motor functions with objective kinematic measures during visuomotor tasks may help differentiating between actual effects of reduced visual acuity on eye-hand coordination in individuals with similar levels of impairment of visual acuity.

Educational policies : implications for equity, equality and equivalence
- 2004
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- This report is part of one of the studies within the project “What about equivalence” granted by The Swedish Research Council and led by Professor Tomas Englund at Örebro University, Sweden. Studying equity, equality and equivalence in education across borders posses a number of challenges associated not only to their conceptualization but to other aspects such as the historical and political dimensions. The different approaches that are found in sociological analysis of educational equity show the underlined complexity. Acknowledging these limitations the aims of this report are threefold. (a) To present main issues concerning the implications for equity, equality and equivalence of the current educational policies in different national educational systems. (b) To present, and to some extent expose for further discussion, what concepts, theoretical grounds and indicators are used to approach the subject at issue. (c) To present some of the current concerns on equity, equality and equivalence in other educational contexts and in Sweden in order to, at a later stage, assess its possible relationship. The report also expects to be a springboard for the further joint enquiry and discussions to come among the scholars who have been involved in its realization and others interested in the subject. The scope is therefore limited to this needed open up to mutual knowledge of perspectives on a complex issue, which is of paramount importance for school practices.The perspectives on equity, equality, and equivalence, which are presented in this report varies indeed concerning both the conceptual frames as well as the methodological approaches used by each contributor. Rather than a hindrance this “diversity” is assumed as a meaningful contribution to the tenet supported in this report that issues of equity, equality and equivalence should be viewed with a broader perspective beyond simple comparison of concepts across national educational systems. The contributions here presented indeed map this broad perspective.

A Strong Correlation Between Dorsolateral Prefrontal Cortex And Vastus Lateralis Activity During Running To Fatigue

Tidskriftsartikel (refereegranskat)abstract
- Fatigue is a phenomenon of pronounced importance in sports. Recently, there is strong evidence of interplay between the prefrontal cortex and motor output during fatiguing contractions. The dorsolateral prefrontal cortex (DLPC) due to its large involvement in cognitive and motor activities is believed to be involved but this requires physiological clarification. AIM: We investigated the relationship between DLPC activity - responses in oxyhemoglobin (HbO2) and total hemoglobin (HbT) measured by near-infrared spectroscopy (NIRS), and the vastus lateralis muscle (VL) activity - quantified as root-mean-square (RMS) of the EMG signal, during a fatigue protocol.METHODS: Four male runners (32±12 yrs) with probes for NIRS over the DLPC and EMG over the VL performed a track running test at a constant speed to fatigue (exhaustion). The running speed was individually determined as the average speed of a 1200-m time trial performed ~3 days prior to testing. For NIRS changes in μmole/L of HbO2 and HbT were computed. The VL EMG-RMS of the contraction of each step was normalized as a percent of a submaximal reference contraction (%RMS), thus removing the non-activity between steps. Data of 10s epochs at 20, 40, 60, 80 and 100% of time for each lap were averaged for analyses. Regression analyses performed with HbO2 and with HbT as dependent variables and %RMS as the independent variable.RESULTS: Over time there was an increase in HbO2 and HbT in the DLPC, and in VL-%RMS. Both HbO2 and HbT correlated strongly with EMG-RMS during running to fatigue (see figures below); p<0.001 for both.CONCLUSION: The strong relationship between DLPC and VL activities during running to fatigue suggests the involvement of the DLPC in the central processing of fatigue.
