Gender-based differences in learner English : A syntax study of Swedish high school students’ written production
No full textFemale students have long had a perceived advantage over male students in second language ac-quisition. In Swedish schools, the girls have outperformed the boys in the subject of English since the end of the Second World War, but the female students’ edge over the male students has diminished considerably over time. This essay aims to find out if there are any differences in lin-guistic ability between the two genders. The study uses a T-unit based syntax analysis in order to quantify the level of syntactic maturity that Swedish high school students possess, using data drawn from the Uppsala Learner English Corpus. Furthermore, the study aims to research gen-der-based stylistic differences and risk-taking behavior in the student’s writing. The results show that there are differences in syntactic maturity between the genders, as the female students in junior high school and the male students in senior high school outperform their respective counterparts, particularly in the indices based on error-free T-units. In addition, there are also stylistic disparities, as the female students have a greater focus on personalized ac-counts in their writing and the male students in junior high school have a very sparse and concise style of writing. The conclusion is drawn that while there are differences in syntactic maturity between boys and girls, the syntactic indices cannot accurately display the sophistication of the students’ writing and consequently should only be used in conjunction with more qualitative measures. Finally, while the study is not able to discern risk-taking in the students’ writing, the author concludes that risk-taking is an important factor in second language acquisition, especially considering the fact that the Swedish curricula in junior and senior high school English have a strong focus on communicative competence
Entre o camelo e o leão a dialética do giro Dervixe: uma etnografia do Sama - a dançaa girante dos Dervixes da ordem Sufi Mevlevi
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em História.Esta dissertação é uma pesquisa etnográfica do Sama, a dança girante inspirada pelo poeta persa Jalaluddin Rumi, em Konya (Turquia), no século XIII. É uma "descrição densa" do ritual, com suas pertinências etno-coreo-musicológicas. Tomando como ponto de partida a Antropologia e a História optei por uma abordagem interdisciplinar, dialogando com a Filosofia, a Poesia, a Dança e a Etnomusicologia. A interpretação envolvida consistiu em salvar o "dito" sob formas pesquisáveis, fixando-o, assim, no quadro geral de práticas místico-filosóficas, tanto orientais quanto ocidentais
Spatial distribution of water level impacting back-barrier bays

K., Defne, Z., & Signell, R. P. Spatial distribution of water level impacting back-barrier bays. Natural Hazards and Earth System Sciences, 19(8), (2019): 1823-1838, doi: 10.5194/nhess-19-1823-2019.Water level in semi-enclosed bays, landward of barrier islands, is mainly driven by offshore sea level fluctuations that are modulated by bay geometry and bathymetry, causing spatial variability in the ensuing response (transfer). Local wind setup can have a complementary role that depends on wind speed, fetch, and relative orientation of the wind direction and the bay. Bay area and inlet geometry and bathymetry primarily regulate the magnitude of the transfer between open ocean and bay. Tides and short-period offshore oscillations are more damped in the bays than longer-lasting offshore fluctuations, such as a storm surge and sea level rise. We compare observed and modeled water levels at stations in a mid-Atlantic bay (Barnegat Bay) with offshore water level proxies. Observed water levels in Barnegat Bay are compared and combined with model results from the Coupled Ocean–Atmosphere–Wave–Sediment Transport (COAWST) modeling system to evaluate the spatial structure of the water level transfer. Analytical models based on the dimensional characteristics of the bay are used to combine the observed data and the numerical model results in a physically consistent approach. Model water level transfers match observed values at locations inside the bay in the storm frequency band (transfers ranging from 50 %–100 %) and tidal frequencies (10 %–55 %). The contribution of frequency-dependent local setup caused by wind acting along the bay is also considered. The wind setup effect can be comparable in magnitude to the offshore transfer forcing during intense storms. The approach provides transfer estimates for locations inside the bay where observations were not available, resulting in a complete spatial characterization. An extension of the methodology that takes advantage of the ADCIRC tidal database for the east coast of the United States allows for the expansion of the approach to other bay systems. Detailed spatial estimates of water level transfer can inform decisions on inlet management and contribute to the assessment of current and future flooding hazard in back-barrier bays and along mainland shorelines.This work was supported by the US Geological Survey, Coastal and Marine Hazards/Resources Program
February 2003 marine atmospheric conditions and the bora over the northern Adriatic
No full textA winter oceanographic field experiment provided an opportunity to examine the atmospheric marine conditions over the northern Adriatic. Mean February winds are from a northeasterly direction over most of the Adriatic and a more northerly direction along the western coast. Wind speeds are fastest in jets over the NE coast during bora events and weakest in the mid-northwestern Adriatic. Diurnal air temperature cycles are smallest on the NE coast and largest in the midwestern Adriatic. The maximum sea-air difference is +10°C on the eastern coast and near zero on the midwestern Adriatic. Boras are northeasterly (from) wind events that sweep off Croatia and Slovenia, bringing slightly colder and drier air over the northern Adriatic. The main bora season is December to March. Winter 2002–2003 was normal for bora events. Synoptic-scale temporal variations are correlated over the northern Adriatic. Fastest Bora winds and highest wind stress over the northern Adriatic is concentrated in four topographically controlled jets. The strongest is the Senj Jet, while the Trieste Jet extends across the entire northern Adriatic. Between each two jets is a weak wind zone. The greatest mean net heat loss is in bora jets in the NE Adriatic, where it was −438 W m−2 and is weakest in the midwestern northern Adriatic, where it was near zero. Wind stress is concentrated over the NE half of Adriatic in four bora jets, while wind stress is weak in the NW Adriatic. There is significant variation in wind stress mean and standard deviation structure over the northern Adriatic with each bora event
Intelligent Equalisation Principles and Techniques for Minimising Masking when Mixing the Extreme Modern Metal Genre.
No full textThe intensity, complexity and energy of performance, combined with the power and density of the tones involved are characteristics of the extreme metal genre. These characteristics present numerous problems when striving to achieve the clarity, definition and hyper-realism of performance required for this genres production. Avoiding masking in a mix is a fundamental
aspect of clarity, definition, intelligibility and perceived loudness and due to the fact that masking especially occurs in a dense mix, and is more pronounced in low frequencies, is particularly applicable to mixing the downtuned extreme metal genre. Masking in simple terms is the ability of frequencies of one sound to obscure or inhibit (i.e. mask) the frequencies of
another sound. This paper will draw upon the first author’s eight years of experience producing within the metal genre, including releases through Sony and Universal and working with the likes of Colin Richardson and Andy Sneap
Technical note: Harmonising metocean model data via standard web services within small research groups
No full textWork over the last decade has resulted in standardised web services
and tools that can significantly improve the efficiency and
effectiveness of working with meteorological and ocean model
data. While many operational modelling centres have enabled query and
access to data via common web services, most small research groups
have not. The penetration of this approach into the research
community, where IT resources are limited, can be dramatically
improved by (1) making it simple for providers to enable web service
access to existing output files; (2) using free technologies that are
easy to deploy and configure; and (3) providing standardised, service-based tools that work in existing
research environments. We present
a simple, local brokering approach that lets modellers continue to use
their existing files and tools, while
serving virtual data sets that can be used with standardised tools.
The goal of this paper is to convince modellers that a standardised framework is not
only useful but can be implemented with modest effort using free software components. We use
NetCDF Markup language for data aggregation and standardisation, the
THREDDS Data Server for data delivery, pycsw for data search, NCTOOLBOX
(MATLAB®) and Iris (Python)
for data access, and Open Geospatial Consortium Web Map Service for
data preview. We illustrate the effectiveness of this approach with
two use cases involving small research modelling groups at NATO and
USGS
BREMSSTRAHLUNG PRODUCTION IN 48-MeV p–p COLLISIONS
No full text Measurements of the cross section d2σ/dΩ1dΩ2 for the bremsstrahlung reaction p + p → p + p + γ were made with 48 ± 1 MeV incident protons. Both final protons were detected in coincidence at equal angles on either side of the beam and coplanar with the beam, and bremsstrahlung events were identified kinematically. Cross sections of 2.12 ± 0.36 and 3.04 ± 0.44 μb/sterad2 were obtained at 30° and 35°, respectively. Both measured cross sections are smaller than the predictions of Signell and Marker by about a factor of 10; this discrepancy is considered to be well established, since various tests show that our detection efficiency is nearly 100%. It is concluded that further theoretical work, especially predictions of cross sections for noncoplanar events, is needed to determine whether the discrepancy results from a strong preference for coplanar events or from some basic defect in the theory. </jats:p
Advancing coastal ocean modelling, analysis, and prediction for the US Integrated Ocean Observing System
No full textThis paper outlines strategies that would advance coastal ocean modeling, analysis and prediction as a complement to the observing and data management activities of the coastal components of the U.S. Integrated Ocean Observing System (IOOS®) and the Global Ocean Observing System (GOOS). The views presented are the consensus of a group of U.S. based researchers with a cross-section of coastal oceanography and ocean modeling expertise and community representation drawn from Regional and U.S. Federal partners in IOOS. Priorities for research and development are suggested that would enhance the value of IOOS observations through model-based synthesis, deliver better model-based information products, and assist the design, evaluation and operation of the observing system itself. The proposed priorities are: model coupling, data assimilation, nearshore processes, cyberinfrastructure and model skill assessment, modeling for observing system design, evaluation and operation, ensemble prediction, and fast predictors. Approaches are suggested to accomplish substantial progress in a 3-8 year timeframe. In addition, the group proposes steps to promote collaboration between research and operations groups in Regional Associations, U.S. Federal Agencies, and the international ocean research community in general that would foster coordination on scientific and technical issues, and strengthen federal-academic partnerships benefiting IOOS stakeholders and end users.Peer reviewe
