    Die Dislokation von Bass und Melodie im klassichen Gitarrenspiel. Eine quantitative und qualitative Studie zu Aufnahmen des Exercice op. 35/22 von Fernando Sor

    Get PDF
    Die Dislokation von Bass und Melodie ist eine Konvention des klassischen Gitarrenspiels, die hier anhand von 46 Aufnahmen einer Etüde von Fernando Sor untersucht wird. Dabei kann um 1980 ein Wandel in der Spielpraxis konstatiert werden, bei dem die durchgehende Dislokation zur Stimmendifferenzierung von einem punktuellen Einsatz derselben als Mittel zur Gestaltung expressiver Gesten abgelöst wurde. Überlegungen zu den Ursachen für diesen Wandel und eine Detailstudie ergänzen den Text

    A Solid-State Battery Cathode with a Polymer Composite Electrolyte and Low Tortuosity Microstructure by Directional Freezing and Polymerization

    Solid‐state Li metal batteries (SSLMBs) combine improved safety and high specific energy that can surpass current Li ion batteries. However, the Li^{+} ion diffusivity in a composite cathode—a combination of active material and solid‐state electrolyte (SSE)—is at least an order of magnitude lower than that of the SSE alone because of the highly tortuous ion transport pathways in the cathode. This lowers the realizable capacity and mandates relatively thin (30–300 μm) cathodes, and hence low overall energy storage. Here, a thick (600 μm) hybrid cathode comprising vertically aligned LiNi_{0.8}Mn_{0.1}Co_{0.1}O_{2} (NMC811)‐rich channels filled with a [LiTFSI+PEGMA+MePrPyl TFSI] polymer composite electrolyte is fabricated by an innovative directional freezing and polymerization method. X‐ray micro‐computed tomography, ion mobility simulations, and DC depolarization show that the cathode structure improves Li^{+} ion diffusivity in the cathode from 4.4 × 10^{-9} to 1.4 × 10^{-7} cm^{2} s^{−1}. In a SSLMB full cell at 25 oC, the cathode provides gravimetric capacities of 199 and 120 mAh g^{−1}, and ultra‐high areal capacities of 16.7 and 10.1 mAh cm^{−2} at 0.05 and 1 C, respectively. The work demonstrates a scalable approach to realizing composite cathode structures with kinetically favorable ion transport characteristics in SSLMBs

    This is the final version. Available from the publisher via the DOI in this record.The datasets generated for this study are available on request to the corresponding authorSmall-scale fisheries are an important source of food, income and cultural identity to millions of people worldwide. Despite many fisher people observing declining catches, a lack of data remains a barrier to understanding the status of small-scale fisheries and their effective management in many places. Where data exist, complex analyses and stock assessments are often beyond the capacity and budgets of local managers. Working with small-scale fisheries in western Madagascar, we analyze landings data to provide a description of the fishery and evaluate the top twenty most commonly caught species for evidence of overfishing. Using length composition data, we use Froese’s three simple rules: Let them spawn, let them grow and let the mega-spawners live, as well as Cope and Punt’s decision tree to infer if spawning biomass is less than target reference points. We then use length-based parameters to calculate fishing mortality and compare with published estimates of natural mortality to assess overfishing (F > M). Over 17,000 fishing trips were registered over a 2-year period (2010–2012), landing just short of 2 million individual fish. Length data were recorded for a sample of over 120,000 individuals. Fish comprised 95% of landings, with the remainder comprised of other groups including crustaceans (mostly shrimp, crab, and lobster), cephalopods, and holothurians. We provide some of the first evidence that fish species caught in the small-scale fisheries of the Menabe region of Madagascar are experiencing overfishing. The most notable result is that for 13 of the 20 most common species, fishing mortality exceeds natural mortality. Many species had a large proportion of individuals (in some cases 100%) being caught before they reached maturity. Very few species were fished at their optimal size, and there were low numbers of large individuals (mega-spawners) in catches. Overfishing in western Madagascar presents a serious threat to the income, food security and well-being of some of the most vulnerable people in the world. The results of this paper support the call for improved management. However, management approaches should take account of overlapping fisheries and be inclusive to ensure the impacts of management do not undermine the rights of small-scale fishers. Further data are needed to better understand the trends and to improve management but should not hinder pragmatic action.European Union’s Regional Coastal Management Programme of the Indian Ocean Countrie

    Enrollment in Science, Technology, Engineering, and Math Courses After Enactment of Texas\u27 House Bill 5

    Student participation and performance in science, technology, engineering, and math (STEM) have been an education concern in the United States for years. In 2013, Texas lawmakers passed House Bill 5 (HB5) to support increases in STEM awareness, particularly among ethnic minority and female students. To date, no studies have been conducted on the impact, if any, of HB5 on Texas high school students’ course selections in STEM areas. Further, it is unknown whether the impact that does exist is equally distributed across socioeconomic status (SES), race/ethnicity, and gender groups. The purpose of this nonexperimental correlational quantitative study was to determine whether there was an increase post-HB5 in STEM course enrollments among African American, Latinx, and female high school students of various SES groups at a Texas regional service center. General systems and stereotype threat theories provided the theoretical framework for the study. Relative changes in enrollments in STEM classes for the 2016-2017 and 2020-2021 school years were computed from archival data from the Texas Education Agency Public Education Information Management System Standard Reports database. Multiple regression analyses were conducted to evaluate student race/ethnicity, gender, and SES as predictors of relative changes in enrollments in STEM courses. There were significant increases in enrollments among female students and decreases among male students across the two years and no differences between ethnicities or SES. Results may help educators and policy makers to understand the possible impact of HB5 on STEM enrollments and possibly develop further initiatives to attract more students to STEM areas leading to positive social change

    INTRODUCTION Posttraumatic pelvic deformity is associated with pain and loss of function. This study aimed to test the correlation of functional outcome in patients with pelvic fractures with the postoperative radiographic quality of reduction. METHODS Consecutive patients with an isolated traumatic pelvic fracture that required closed or open reduction between 07/2015 and 07/2017 and had a completed follow-up of at least 6 months were included (N = 31, mean age 50 years, SD 21 years, range, 16 to 88 years). Majeed and Timed Up & Go were obtained from a prospective outcome database at 6 months and last follow-up (mean 10 months, SD 5 months). Quality of pelvic ring reduction was determined on postoperative radiographs as described by Matta, Sagi and Keshishyan/Lefaivre. RESULTS Clinical outcome at 6 months as measured by the Majeed and the Timed Up & Go correlated moderately with Keshishyan/Lefaivre's pelvic asymmetry value (Pearson R: -0.520 and 0.585, p ≤ 0.003) and the pelvic deformity index (-0.527 and 0.503, p ≤ 0.004). There was a weak correlation between the Timed Up & Go and the radiographic grading system as described by Matta/Tournetta at 6 months (0.408, p = 0.023) and at last follow-up (0.380, p = 0.035). CONCLUSIONS This study showed a moderate correlation of the clinical outcome at 6 months with postoperative quality of radiographic reduction when measured with the method described by Keshishyan and Lefaivre. Although having only descriptive value due to the small cohort, our findings underline the importance of anatomic reduction and restoration of pelvic symmetry in patients with pelvic trauma. Future studies with more patients and more investigators are required and reliability and validity of functional outcome scores needs to be further assessed to predict outcome in patient with fractures of the pelvic ring.

    Every day the need to understand earthquakes and how that phenomenon affects construction grows, to make it possible to prevent and minimize inherent risks to their relation. That need increases when projects are located in regions with large seismicity. Therefore, the present paper, which was developed in partnership with GEG ? Gabinete de Estruturas e Geotecnia, has, as a final goal, to study and compare the variety of calculation methods available on Eurocode 8 to design and evaluate earthquake resistant structures, using a real case study. The methods approached are linear dynamic analysis, also known as spectral analysis, nonlinear static analysis, also recognized as pushover analysis, and non-linear dynamic analysis, well-known as time-history analysis. Simultaneously to the seismic analyses, it is developed a detailed study of the parameters that affect the damping of soil-structure interaction.6612-034D-AE05 | PEDRO DA SILVA DELGADON/
