Effects of Stimulus Duration and Type on Perception of Female and Male Speaker Age
- 2005
-
In: Proceedings of Fonetik 2005. - 9197389595 ; , s. 87-90
-
Conference paper (peer-reviewed)abstract
- Our abilitiy to estimate speaker age was investigated with respect to stimulus duration and type as well as speaker gender in four listening tests with the same 24 speakers, but with four different types of stimuli (ten and three seconds of spontaneous speech, one isolated word and six concatenated isolated words). Results showed that the listeners' judgements were about twice as accurate as chance, and that stimulus duration and type affected the judgements. Moreover, stimulus duration affected the listeners’ judgments of female speakers somewhat more, while stimulus type affected the judgments of male speakers more, indicating that listeners may use different strategies when judging female and male speaker age.

Development of an algorithm for determination of the likelihood of virological failure in HIV-positive adults receiving antiretroviral therapy in decentralized care
- 2017

In: Global Health Action. - : Informa UK Limited. - 1654-9716 .- 1654-9880. ; 10:1
-
Journal article (peer-reviewed)abstract
- Background: Early identification of virological failure (VF) limits occurrence and spread of drug-resistant viruses in patients receiving antiretroviral treatment (ART). Viral load (VL) monitoring is therefore recommended, but capacities to comply with this are insufficient in many low-income countries. Clinical algorithms might identify persons at higher likelihood of VF to allocate VL resources. Objectives: We aimed to construct a VF algorithm (the Viral Load Testing Criteria; VLTC) and compare its performance to the 2013 WHO treatment failure criteria. Methods: Subjects with VL results available 1 year after ART start (n = 494) were identified from a cohort of ART-naïve adults (n = 812), prospectively recruited and followed 2011-2015 at Ethiopian health centres. VF was defined as VL≥1000 copies/mL. Variables recorded at the time of sampling, with potential association with VF, were used to construct the algorithm based on multivariate logistic regression. Results: Fifty-seven individuals (12%) had VF, which was independently associated with CD4 count <350 cells/mm3, previous ART interruption, and short mid-upper arm circumference (<24cm and <23cm, for men and women, respectively). These variables were included in the VLTC. In derivation, the VLTC identified 52/57 with VF; sensitivity 91%, specificity 43%, positive predictive value (PPV) 17%, negative predictive value (NPV) 97%. In comparison, the WHO criteria identified 38/57 with VF (sensitivity 67%, specificity 74%, PPV 25%, NPV 94%). Conclusions: The VLTC identified subjects at greater likelihood of VF, with higher sensitivity and NPV than the WHO criteria. If external validation confirms this performance, these criteria could be used to allocate limited VL resources. Due to its limited specificity, it cannot be used to determine treatment failure in the absence of a confirmatory viral load.

Traces of existence : Kattun är Cotton
- 2018
-
Artistic work (peer-reviewed)abstract
- For this project, I was invited by the Jewish Museum in Stockholm to create a site specific installation based on the history of block printed-cotton fabrics. At the end of the 18th century, thanks to Jewish businessmen, Indian and Persian patterns made their way to Sweden. These patterns are now considered typically Swedish, despite their eastern origins. To me, this multifaceted project came to be about identity, craftsmanship and cultural appropriation.5 MAJ – 2 SEP, 2018

Journal article (peer-reviewed)abstract
- Developing a sound ability of noticing is a crucial competency for both teachers and medical professionals in the respective professional and disciplinary communities. In this article, we investigate noticing in practice-how members of a professional community in the high-tech modern medicine specialty of Advanced Heart Failure use this ability toward developing and sustaining what it means to be a competent practitioner and what counts as a relevant practice of noticing in their moment-to-moment training. A multimodal analysis of videotaped practice is conducted on professionals interactions who are simultaneously engaged in multiple activities:patient careandteaching and learningin graduate medical education. Toward this end, we expand the concept of noticing to (1) include a relational aspect, attending to and caring for the Other (students, patients); and (2) shift the analytic focus from an observers interpretation of a scene to a concerted production of the scenic features to make sense ofnoticing in practice.

Influence of bacteria on shell dissolution in dead gastropod larvae and adult Limacina helicina pteropods under ocean acidification conditions
- 2018
-
In: Marine Biology. - : Springer Science and Business Media LLC. - 0025-3162 .- 1432-1793. ; 165:2
-
Journal article (peer-reviewed)abstract
- Ocean acidification (OA) increases aragonite shell dissolution in calcifying marine organisms. It has been proposed that bacteria associated with molluscan shell surfaces in situ could damage the periostracum and reduce its protective function against shell dissolution. However, the influence of bacteria on shell dissolution under OA conditions is unknown. In this study, dissolution in dead shells from gastropod larvae and adult pteropods (Limacina helicina) was examined following a 5-day incubation under a range of aragonite saturation states (Omega(arag); values ranging from 0.5 to 1.8) both with and without antibiotics. Gastropod and pteropod specimens were collected from Puget Sound, Washington (48 degrees 33'19.N, 122 degrees 59'49''W and 47 degrees 41'11''N, 122 degrees 25'23''W, respectively), preserved, stored, and then treated in August 2015. Environmental scanning electron microscopy (ESEM) was used to determine the severity and extent of dissolution, which was scored as mild, severe, or summed (mild + severe) dissolution. Shell dissolution increased with decreasing Omega(arag). In gastropod larvae, there was a significant interaction between the effects of antibiotics and Omega(arag) on severe dissolution, indicating that microbes could mediate certain types of dissolution among shells under low Omega(arag). In L. helicina, there were no significant interactions between the effects of antibiotics and Omega(arag) on dissolution. These findings suggest that bacteria may differentially influence the response of some groups of shelled planktonic gastropods to OA conditions. This is the first assessment of the microbial-chemical coupling of dissolution in shells of either gastropod larvae or adult L. helicina under OA.

Knowledge management in the making: using the balanced scorecard and e-mail systems
- 2006
-
In: Journal of knowledge management. - : Emerald Group Publishing Limited. - 1758-7484 .- 1367-3270. ; 10:3, s. 86-102

Journal article (peer-reviewed)abstract
- Purpose - Knowledge management deals with the production, application, and distribution of knowledge within and between organizations. Such intellectual resources do not appear ex nihilo, but are always constituted through practices and undertakings in an everyday work life setting. This paper seeks to examine how two managerial tools, the balanced scorecard and an e-mail system, are used to represent and classify various knowledge-based resources in two organizations.Design methodology approach - The paper draws on Foucault's perhaps least recognized work, The Birth of the Clinic and shows how what Foucault calls sensible knowledge is useful for understanding BSC and the e-mail system. Sensible knowledge integrates a number of human faculties such as ocular, representational, and communicative skills in many cases taken for granted and poorly considered in organization theory. Two case studies serve as the primary empirical domain.Findings - The paper concludes that knowledge can never be taken for granted, but must always be examined at the level of its constitution and reproduction, i.e. within the regimes of representation and classification in which practitioners operate. Such regimes of representation and classification are immanent in a variety of managerial tools and technological systems and must therefore be examined in greater details.Research limitations implications - The immediate implications from managerial tools and technological systems need to be studied in their context and understood as principal resources for managing knowledge in practice.Originality value - The paper bridges theoretical writings on representation classification, sensible knowledge and the more mundane everyday work life practices that constitute organizations.

Reconstructing extreme climatic and geochemical conditions during the largest natural mangrove dieback on record
- 2020

In: Biogeosciences. - : Copernicus GmbH. - 1726-4170 .- 1726-4189. ; 17:18, s. 4707-4726

Journal article (peer-reviewed)abstract
- A massive mangrove dieback event occurred in 2015-2016 along similar to 1000km of pristine coastline in the Gulf of Carpentaria, Australia. Here, we use sediment and wood chronologies to gain insights into geochemical and climatic changes related to this dieback. The unique combination of low rainfall and low sea level observed during the dieback event had been unprecedented in the preceding 3 decades. A combination of iron (Fe) chronologies in wood and sediment, wood density and estimates of mangrove water use efficiency all imply lower water availability within the dead mangrove forest. Wood and sediment chronologies suggest a rapid, large mobilization of sedimentary Fe, which is consistent with redox transitions promoted by changes in soil moisture content. Elemental analysis of wood cross sections revealed a 30- to 90-fold increase in Fe concentrations in dead mangroves just prior to their mortality. Mangrove wood uptake of Fe during the dieback is consistent with large apparent losses of Fe from sediments, which potentially caused an outwelling of Fe to the ocean. Although Fe toxicity may also have played a role in the dieback, this possibility requires further study. We suggest that differences in wood and sedimentary Fe between living and dead forest areas reflect sediment redox transitions that are, in turn, associated with regional variability in groundwater flows. Overall, our observations provide multiple lines of evidence that the forest dieback was driven by low water availability coinciding with a strong El Nino-Southern Oscillation (ENSO) event and was associated with climate change.
