103. Preparations for Modelling the Relationship between Competence and Qualifications. No. 77.

Author

Abstract

This report presents basic theoretical and methodological assumptions for investigating the relationship between competence and qualifications by means of simulation tasks. An analysis of the types of tasks that have been used in the study of problem solving psychology serves as a background for an exposition of the relationship between competence and qualifications. The vehicle for investigating competence and qualifications is the INTOPIA computer program, which simulates a virtual international reality of global enterprises from construction of plants to the sale and financing of products. Findings are reported from a pilot experiment involving two teams of two adults each, the aim of which was to examine the feasibility of using the program in research. Findings indicate that the number of sessions needs to be reduced from the amount used in the teaching situation for which it was developed originally. The issues for investigation in a forthcoming experiment and the tool to be used for modeling the behavior of subjects are outlined. (Contains 35 references.) (Author/SLD)

Abstract

OBJECTIVES: Traditional jumping-dance rituals performed by Maasai men involve prolonged physical exertion that may contribute significantly to overall physical activity level. We aimed to objectively quantify the metabolic intensity of jumping-dance activity and assess associations with habitual physical activity and cardiorespiratory fitness (CRF).METHODS: Twenty Maasai men (18-37 years) from rural Tanzania volunteered to participate in the study. Habitual physical activity was monitored using combined heart rate (HR) and movement sensing over 3 days, and jumping-dance engagement was self-reported. A 1-h jumping-dance session resembling a traditional ritual was organized, during which participants' vertical acceleration and HR were monitored. An incremental, submaximal 8-min step test was performed to calibrate HR to physical activity energy expenditure (PAEE) and assess CRF.RESULTS: Mean (range) habitual PAEE was 60 (37-116) kJ day -1 kg -1 , and CRF was 43 (32-54) mL O 2 min -1 kg -1 . The jumping-dance activity was performed at an absolute HR of 122 (83-169) beats·min -1 , and PAEE of 283 (84-484) J min -1 kg -1 or 42 (18-75)% when expressed relative to CRF. The total PAEE for the session was 17 (range 5-29) kJ kg -1 , ~28% of the daily total. Self-reported engagement in habitual jumping-dance frequency was 3.8 (1-7) sessions/week, with a total duration of 2.1 (0.5-6.0) h/session. CONCLUSIONS: Intensity during traditional jumping-dance activity was moderate, but on average sevenfold higher than habitual physical activity. These rituals are common, and can make a substantial contribution to overall physical activity in Maasai men, and thus be promoted as a culture-specific activity to increase energy expenditure and maintain good health in this population.

133. Row-Column Beamformer for Fast Volumetric Imaging

Abstract

A row-column beamformation algorithm is presented, which yields the output from the conventional delay-and-sum algorithm while reducing the number of operations by order of magnitude. The proposed method uses that in a row-column synthetic aperture sequence, the low-resolution volumes (LRV) have approximately constant image values along the elevation axis. It is, thus, possible to reconstruct the entire LRV from a single cross-section by modeling the positions with constant image values. As such, the proposed method consists of two stages. The first stage beamforms a low-resolution image per emission using the conventional approach. The second stage reconstructs the LRVs with one interpolation per voxel. Lastly, a high-resolution volume (HRV) is obtained by summing the LRVs across all emissions. The proposed algorithm was evaluated on measured data acquired using a 6 MHz 128+128 Vermon row-column probe and a Verasonics Vantage system. The proposed method beamformed a $100 \times 100 \times 200$ HRV consisting of 48 LRVs at a volume rate of 38 Hz. This was 9.23 times faster than a published GPU implementation of the conventional approach and real-time volumetric beamformation was achieved with a pulse repetition frequency of up to 1805 Hz. The output from the conventional and proposed beamformer was visually indistinguishable, and their point spread function's width heccurate interpolation requiright at -6 dB and -20 dB deviated less than 0.5%. This demonstrates that the number of operations of the conventional row-column beamformer can be significantly reduced with a negligible impact on image quality.

Abstract

Seal finger (sealer’s finger, spekk finger), an extremely painful hand infection contracted by individuals handling seals, has previously been associated with Mycoplasma phocacerebrale. From 2000 to 2014, six independent strains of a novel Mycoplasma species were isolated at Statens Serum Institut, Denmark, from Scandinavian patients with seal finger (M5725T, M6447, M6620, M6642 and M6879) or septic arthritis (M6921). Prior to the onset of infection, all patients had reported contact with unspeci-ated seals. All isolates grew within 2–5 days in Friis’ modified broth and metabolized glucose and arginine but not urea. Strains M5725T, M6447, M6642 and M6921 also grew in Hayflick-type media. Colonies on agar media were large (0.5–1.0 mm) and had a typical ‘fried egg’ appearance, reduced tetrazolium, and were digitonin sensitive. Growth occurred at 32 °C but not at 42 °C. Strains were susceptible to doxycycline and moxifloxacin but resistant to azithromycin and erythromycin. The genomes of the six strains were sequenced and relatedness to all known Mycoplasma species was inferred. Phylogenetic analyses using 16S rRNA gene sequences and core genome single nucleotide polymorphisms showed that the isolated strains were highly similar and phylogenetically distinct from all other species within the genus Mycoplasma. The sizes of the genome sequences of the strains ranged from 744 321 to 772409 bp, with a G+C content of 25.0–25.2 mol%. Based on these analyses, we propose a novel species of the genus Mycoplasma with the name Mycoplasma phocimorsus sp. nov. with the first isolate M5725T (NCTC 14922T=DSM 116188T) as the proposed type strain and representative strains M6447, M6620, M6642, M6879 and M6921.

Abstract

Objectives To determine the phenotypic and genotypic antibiotic susceptibility of Mycoplasma amphoriforme isolates recovered from patients in the UK and Denmark. Methods Seven isolates of M. amphoriforme were examined for antimicrobial susceptibility to seven antibiotics using the microbroth dilution assay in line with the CLSI guidelines for mycoplasmas. Each isolate was additionally subjected to WGS to identify resistance-associated mutations. Based on the consensus sequences from the genomic data, PCR primers were designed, and tested, for the amplification of the QRDR within the parC gene. Results Of the seven isolates investigated, four (57%) were resistant to moxifloxacin (0.5–1 mg/L) and levofloxacin (1–2 mg/L), compared with those that were susceptible (0.03–0.06 and 0.006 mg/L, respectively). Isolate H29 was resistant to five of the seven antibiotics tested: moxifloxacin, 0.5 mg/L; levofloxacin, 2 mg/L; azithromycin, 64 mg/L; erythromycin, 128 mg/L; and clindamycin, 64 mg/L. All isolates were susceptible to tetracycline (0.06 mg/L) and lefamulin (0.001–0.004 mg/L). Mutations from genomic data confirmed the presence of an S89F mutation within the ParC protein among all fluoroquinolone-resistant isolates and an A2059G mutation in the 23S rRNA gene in the macrolide- and lincosamide-resistant isolate H29. Conclusions To the best of our knowledge, this is the first time where phenotypic and genotypic resistance data have been paired for M. amphoriforme confirming a correlation between the two. These data suggest the need for focused testing and resistance determination of isolates from high-risk patients given the backdrop of a high prevalence of antimicrobial resistance.
