En båge genom tiden - ritualer kring en göteborgshistoria. Om Flickläroverket i Artisten
- 2024
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- 1929 bildades Göteborgs första Högre allmänna läroverk för Flickor – Flickläroverket som fick en byggnad 1935 i det kulturella centrumet, Götaplatsen. Efter några år som Kjellbergska gymnasiet, sedan Komvux, blev byggnaden del av Artisten, Högskolan för scen och musik, HSM 1992. Byggnaden har burit kvinnors utbildning, konst och kultur över många generationer, en minneskedja som nu är bruten. Boken - En båge genom tiden – ritualer kring en göteborgshistoria – en konst- och forskningsantologi – är resultatet av de offentliga minnesdagar där de deltagande drygt 200 kvinnorna (70– 97 år) som varit elever på Flickläroverket, studenter vid Artisten, konstnärer och forskare – bidrog till och deltog i gestaltande ritualer, minnesrum, dans, utställningar och samtal som gav liv åt en utbildningskultur och konst som berört samhället i generationer. I boken bidrar ett 20-tal Göteborgsbaserade konstnärer och forskare med olika perspektiv på byggnadens poetiska, sociala och konstnärliga dimensioner. Bland annat beskrivs återskapandet av Bågdansen, som dansades varje år vid Lucia mellan 1934-1972. Här beskrivs även den medie-debatt som ledde till räddningen av målningen Dansen av Nils Nilsson från 1935 och hur nedtagningen gick till. Tillsammans med ett rikt foto- och bildmaterial, filmdokumentationer och ett ljudarkiv utgör boken ett tidsdokument där konst fungerar som minnesbärare över tid och rum.

Beyond social-ecological traps : fostering transformations towards sustainability
- 2021
-
Ingår i: Ecology and Society. - 1708-3087. ; 26:1
-
Tidskriftsartikel (refereegranskat)abstract
- This Special Feature is motivated by the rigorous, and growing, theoretical and empirical body of literature on social-ecological traps. Building on the foundational literature, which describes the context in many of the places where we work, we now look forward and ask how we can better understand and enable the breaking and escaping of social-ecological traps. In this Special Feature we focus on this frontier in the field and use the trap metaphor as a unifying framework for collating empirically derived insights on overcoming challenges across diverse geographies, sectors, and social-ecological contexts. We requested contributions to this feature that, as well as possible under each context, explore tangible pathways for disrupting social-ecological traps. Thematic relevance and clear contribution to social-ecological scholarship was emphasized in the invited contributions, but authors were not constrained by methodological approach, context, geographical location, or sector. Our ambition with this editorial is to synthesize the novel insights these papers highlight and situate their contributions within the relevant literature.

Breaking degradation of sea cucumber resources: a social-ecological analysis of the fisheries in Zanzibar and Mayotte Islands in the Western Indian Ocean
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Despite increasing research and management attention to tropical sea cucumber fisheries no apparent successes have been documented. To broaden the perspective of recent advances in management tools this study analyses the social-ecological processes in two contrasting sea cucumber fisheries situations, Zanzibar (Tanzania) and Mayotte (France) in the Western Indian Ocean. Zanzibar has an on-going fishery while the fishery in Mayotte operated approximately 10 years before it was closed in 2004. The study compares how different management strategies in Mayotte and Zanzibar were taken to address increasing fishing effort and a declining sea cucumber population. The comparison provide an opportunity learning and reflection. A visual census of stocks shows that the commercial value is nearly 30 times higher in Mayotte than Zanzibar owing to different fishery and management practices. In Mayotte less than 100 people were engaged in the fishery when it was active and the fishery was a comparatively small enterprise. In contrast, over 1000 people collect sea cucumbers as part of an expansive trade network that has developed in Zanzibar. In addition, in this site fishers are dependent on the resource for livelihood and expanding fishery processes have therefore occurred as a response to declines in catch abundance and value. These responses have taken place in the context of insufficient management and reinforce an unsustainable fishery situation difficult to break – referred to as a social-ecological trap. In contrast, management in Mayotte was receptive and adaptive to changes. The closure of the fishery illustrates the importance and positive outcome of matching the fishery – management temporal scales to avoid reinforcing fishery processes and to maintain ecosystem integrity. The multiple fisheries targeting sea cucumbers documented in this study captures how different management approaches and management plans are required, building on an understanding of the social-ecological context of the fishery. In addition, the comparison illustrates the importance of management systems with adequate resources (e.g. human and economic) and functioning information flows for positive management outcomes.

Tidskriftsartikel (refereegranskat)abstract
- Small-scale fisheries present challenges to management due to fishers' dependency on resources and the adaptability of management systems. We compared social-ecological processes in the sea cucumber fisheries of Zanzibar and Mayotte, Western Indian Ocean, to better understand the reasons for resource conservation or collapse. Commercial value of wild stocks was at least 30 times higher in Mayotte than in Zanzibar owing to lower fishing pressure. Zanzibar fishers were financially reliant on the fishery and increased fishing effort as stocks declined. This behavioral response occurred without adaptive management and reinforced an unsustainable fishery. In contrast, resource managers in Mayotte adapted to changing fishing effort and stock abundance by implementing a precautionary fishery closure before crossing critical thresholds. Fishery closure may be a necessary measure in small-scale fisheries to preserve vulnerable resources until reliable management systems are devised. Our comparison highlighted four poignant lessons for managing small-scale fisheries: (1) diagnose the fishery regularly, (2) enable an adaptive management system, (3) constrain exploitation within ecological limits, and (4) share management responsibility.

Mobility, Expansion and Management of a Multi-Species Scuba Diving Fishery in East Africa
- 2012
-
Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 7:4, s. e35504-
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Scuba diving fishing, predominantly targeting sea cucumbers, has been documented to occur in an uncontrolled manner in the Western Indian Ocean and in other tropical regions. Although this type of fishing generally indicates a destructive activity, little attention has been directed towards this category of fishery, a major knowledge gap and barrier to management. Methodology and Principal Findings: With the aim to capture geographic scales, fishing processes and social aspects the scuba diving fishery that operate out of Zanzibar was studied using interviews, discussions, participant observations and catch monitoring. The diving fishery was resilient to resource declines and had expanded to new species, new depths and new fishing grounds, sometimes operating approximately 250 km away from Zanzibar at depths down to 50 meters, as a result of depleted easy-access stock. The diving operations were embedded in a regional and global trade network, and its actors operated in a roving manner on multiple spatial levels, taking advantage of unfair patron-client relationships and of the insufficient management in Zanzibar. Conclusions andSignificance: This study illustrates that roving dynamics in fisheries, which have been predominantly addressed on a global scale, also take place at a considerably smaller spatial scale. Importantly, while proposed management of the sea cucumber fishery is often generic to a simplified fishery situation, this study illustrates a multifaceted fishery with diverse management requirements. The documented spatial scales and processes in the scuba diving fishery emphasize the need for increased regional governance partnerships to implement management that fit the spatial scales and processes of the operation.

Cortical changes during the learning of sequences of simultaneous finger presses
- 2023
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The cortical alterations underpinning the acquisition of motor skills remain debated. In this longitudinal study in younger adults, we acquired performance and neuroimaging (7T MRI) measures weekly over the course of 6 weeks to investigate neural changes associated with learning sequences of simultaneous finger presses executed with the non-dominant hand. Both the intervention group (n = 33) and the control group (n = 30) showed general performance improvements, but performance improved more and became more consistent for sequences that were intensively trained by the intervention group, relative to those that were not. Brain activity for trained sequences decreased compared with untrained sequences in the bilateral parietal and premotor cortices. No training-related changes in the primary sensorimotor areas were detected. The similarity of activation patterns between trained and untrained sequences decreased in secondary, but not primary, sensorimotor areas, while the similarity of the activation patterns between different trained sequences did not show reliable changes. Neither the variability of activation patterns across trials, nor the estimates of brain structure displayed practice-related changes that reached statistical significance. Overall, the main correlate of learning configural sequences was a reduction in brain activity in secondary motor areas.

In this longitudinal study in younger adults, we acquired performance and neuroimaging (7 T MRI) measures weekly over the course of 6 weeks to investigate neural changes associated with learning sequences of simultaneous finger presses executed with the non-dominant hand. Both the intervention group (n = 33), which practiced the finger sequences at home, and thecontrol group (n = 30, no home practice) showed general performance improvements, but performance improved more and became more consistent for sequences that were intensively trained by the intervention group, relative to those that were not. Brain activity for trained sequences decreased compared with untrained sequences in the bilateral parietal and premotor cortices. No training-related changes in the primary sensorimotor areas were detected.

Cross-vendor transfer and RF coil comparison of a high-resolution MP2RAGE protocol for brain imaging at 7T
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Abstract. An established MP2RAGE protocol for semi-quantitative structural brain MRI was transferred from one 7T MR scanner to that of another vendor featuring comparable hardware, but opposite polarity. On this system, the scan time could be reduced from 11 to 8 minutes by elliptical k-space sampling. Three configurations of radio-frequency (RF) transmission were compared (single channel with quadrature slitting, two and eight channels of fixed phase delays). Data processing for offline calculation MP2RAGE images is described in detail. The DICOM scaling of scanner B entails a loss of precision and accuracy and stronger artifacts in regions of low RF field, which can be improved by dielectric pads. For comparison and multi-site studies, though, use of an identical scan protocol and identical RF hardware is recommended.

Konferensbidrag (refereegranskat)abstract
- Fitting the inversion recovery (IR) at multiple TI provides T1 estimates of high accuracy if performed in a single slice with full relaxation. We present anisotropic 3D variant based on MP-RAGE, where a T1-weighted driven equilibrium is prepared prior to inversion by a second RAGE readout. This abolishes the need for long recovery times and provides volumes of similar contrast for co-registration. The method was tested at 3T on a small cohort andcompared to 3D IR-TSE and 3D variable flip angle mapping.
