Purpose

The study aimed to examine the validity of self-reporting as an additional method to indicate gait alteration among patients with idiopathic normal pressure hydrocephalus. The score from self-reporting of gait alteration was validated with the data obtained from gait pressure measuring plate. In addition, temporo-spatial gait parameters among 3 groups classified by overall gait improvement (no change, slight, and good) were compared.

Methods

This study employed a cross-sectional design and investigated 31 patients with idiopathic normal pressure hydrocephalus. Gait performance was determined by a gait pressure measuring plate before and 24 hours after a tap test. Patients rated the changed score for gait behaviours using a questionnaire once on the day after the tap test. Criterion validity of the changed scores from patients’ self-reporting and data from the gait pressure measuring plate was examined. In addition, temporo-spatial gait parameters were compared among 3 groups with one-way analysis of variance and the Bonferroni posthoc test to determine pairwise difference.

Results

Significant correlations were found for the temporo-spatial gait parameters between data from self-reporting and the gait pressure measuring plate. Comparisons of temporo-spatial gait parameters among groups demonstrated significant differences in all parameters.

Conclusions

Gait alteration identified by self-reporting was valid with gait performance measured by the gait pressure measuring plate. To achieve timely and appropriate medical management, we recommend health care professionals to request patients and caregivers to recognize gait alterations in assisting the disease progression identification.

Published: August 2021

Purpose

We analysed the effects of moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) on hepatic and adipose tissue aquaglyceroporins (AQPs) in rats fed with high-fat diet (HFD).

Methods

Overall, 48 male Wistar rats were fed with a normal diet (ND, 10.4 kcal% fat) or HFD (62.1 kcal% fat) over 10 weeks. Then, the animals were divided into 6 groups: ND sedentary (NS), N + MICT, N + HIIT, HS, H + MICT, and H + HIIT. The trained animals performed 10-week matched distances of MICT and HIIT on a motorized treadmill (5 times/week) while maintaining dietary treatments. The liver and epididymal white adipose tissue (eWAT) were investigated to determine triglycerides (TG) and AQP7 and AQP9 levels.

Results

HFD increased body weight, liver and eWAT weight, plasma insulin and glucose levels, and insulin resistance. Both MICT and HIIT were able to decrease body weight and liver and eWAT weight in the HFD-fed group. HFD increased plasma TG, glucose, and insulin levels, attenuated by MICT and HIIT programs. HFD increased TG content and AQP7 and did not alter AQP9. MICT and HIIT programs decreased hepatic TG content and AQP7 and AQP9 levels in ND-fed animals. In HFD-fed animals, only MICT decreased AQP9, and both MICT and HIIT decreased TG content and AQP7 levels in eWAT.

Conclusions

Our findings suggest that the regulation of adipose tissue AQP7 and hepatic AQP9 by both MICT and HIIT interventions can have a significant effect on fat metabolism and glucose homeostasis.

Numerous restaurants fight for the best quality for clients in the increasingly competitive restaurant sector. A restaurant is a business that demands more attention to customer care through continually enhancing customer service. The situation has an effect on the restaurant’s brand image, which is shaped by whether or not consumers are happy. Restaurant patrons may choose to benefit from others’ experiences by evaluating restaurants based on a range of factors, including meal quality, service, ambience, discounts, and deservingness. Users may leave reviews and ratings of companies and services, or just comment on other reviews. From one standpoint, bad (negative) reviews may influence how potential consumers make purchasing decisions. Sentiment analysis is a technique for determining the emotional content of a text that may be used to evaluate product/service reviews. Additionally, we may categorise them as positive or negative emotions. Understanding how the general public feels about various entities and products enables more relevant marketing, recommendation systems, and market trend research. Prepossessed data is collected, and then categorization is performed using a confusion matrix. This study enables us to create a report on the public’s perception of a particular restaurant. We developed a machine learning model and trained it using Bernoulli’s Naive Bayes classifier. Additionally, we evaluated the classifier’s performance on the test sample using evaluation matrices such as prediction, accuracy, recall, and F1 score. Customer review research has a significant influence on a business’s growth strategy.

Práxis Antirracista, Descolonização das Mentes e a Questão Indígena em uma Instituição Federal de Ensino Superior do Sertão Pernambucano
Authors: Santana Paula
Published: August 2021

A educação brasileira tem sido apontada, pelas pesquisas oficiais e acadêmicas, assim como pelos movimentos sociais e, em especial, pelo Movimento Social Negro e Indígena, como um espaço/tempo no qual persistem históricas desigualdades sociais e raciais. Esta situação exige do Estado a adoção de políticas e práticas de superação do racismo e da desigualdade racial na educação, as quais começam a ser implementadas de forma mais sistemática nos anos 2000, a partir da implementação das leis n° 10.639/2003 e n° 11.645/2008, que regulamentam a obrigatoriedade do ensino da História e Cultura Afro-brasileira e Indígena em todos os níveis de ensino. É no bojo dessas experiências que este artigo surge, em um esforço de perceber e compreender a invisibilidade, os preconceitos e formas de discriminação e racismo operados contra os povos indígenas do entorno do campus a partir das vivências dos estudantes que cursaram a disciplina ‘Educação para as Relações Étnico-raciais’.

The development of road safety assessment screening procedures for the City Tshwane Metropolitan Municipality
Authors:   , Sarjoo Arvin Ramsunder
Published: August 2021

The word “accident” is a familiar term used to describe a collision involving one or more transportation vehicles that results in property damage, injury or death. The term implies a random event that occurs due to no specific reason other than human error or unforeseen circumstances. The American National Highway Traffic Safety Administration (NHTSA) suggests replacing the word “accident” with “crash” as the word “crash” implies that the collision could have been prevented or minimised by improving driver behaviour, vehicle design, roadway geometry or the environment (Garber and Hoel 2015: 150). In the global context, South Africa, as is characteristic of many developing countries with limited resources, faces the challenge to proactively managing, reducing and eliminating the high incidence of road crashes, injuries and fatalities. Due to an absence of routine Road Safety Assessment and Audit procedures within the relevant departments at the City of Tshwane Metropolitan Municipality (CTMM), the main aim of this research was to develop procedures with measurable benefits which would promote a safer road environment. The data analysis and findings describe statistically significant relationships between Average Daily Traffic (ADT) as the independent variable and Accident Frequency as the dependant variable. The linear regression models and equations as developed allowed for the prediction of crash rates and the prioritisation of CTMM road safety projects. The findings indicated significant increases in accident rates on higher order roads (typically traffic signalled controlled intersections) with factors such as a greater number of intersection conflict points, greater pedestrian volumes and increased intersection saturation or volume/capacity levels contributing to higher accident rates. Intersection controls and traffic safety measures such as traffic circles, traffic signals, and traffic signs were assessed for effectiveness in reducing the Rate of Accidents per Million of Entering Vehicles (RMEVs). The research highlights the vulnerability of Non-Motorised Transport (NMT) (particularly pedestrians) which contributed to approximately 40% of all accident fatalities (Department of Transport 2016: 31). The recommendation therefore is for a road safety assessment and screening process to focus and allocate greater resources in the effort to proactively reduce the number of pedestrian fatalities.

İnsanoğlu hayatını kolaylaştırabilmek ve değişen dünyanın en güncel haline uyum sağlamak için birçok alanda olduğu gibi para için kullanılan nesnelerde de bazı değişikliklere gitmiştir. Bu süreçte deniz kabuklarını, fil dişlerini, değerli madenleri para olarak kullanmışlardır. Teknolojinin gelişmesiyle beraber para olarak kullanılan nesnelerde değişmiştir. Bu bağlamda özellikle son yıllarda blokzincir teknolojisi üzerine inşa edilen kripto paralar birçok ülkenin, finansal kurumların dikkatini çekmiştir. Buna paralel olarak kripto paraların kullanım alanı oldukça artmıştır. Bu çalışmada blokzincir teknolojisinin altyapısı, finans sektöründeki yeri, sosyal hayattaki kullanım alanları, avantajları, dezavantajları ve kripto paraların merkez bankaları, finans piyasaları üzerindeki öngörülen etkileri incelenmiştir. Yapılan birçok çalışmada blokzincir teknolojisinin henüz çok yeni bir teknoloji olduğu ve gün geçtikçe hayatı kolaylaştırıcı farklı bir kullanım alanı ortaya çıktığı tespit edilmiştir. Genel olarak Blokzincir teknolojisinin maliyet, hız, güvenlik gibi alanlarda kurum/kuruluşlara fayda sağlayacağı düşünülmektedir. Kripto paraların ise aşırı riskli olduğu, özellikle terör örgütlerine finansman sağlama, vergi kaçırma kara para aklama gibi faaliyetlerle devletleri zarara uğratabileceği öngörülmektedir. Kripto paralar ile ilgili yasal düzenlemelerin yapılmasının zorunlu olduğu, ilerleyen zamanlarda kripto para kullanımının daha da artacağı fakat buna rağmen ülkelerin merkez bankalarının yerini almasının zor olduğu düşünülmektedir.
Prediction of Secondary Organic Aerosol from the Multiphase Reaction of Gasoline Vapor by Using Volatility–Reactivity Base Lumping
Authors: Han Sanghee , Jang Myoseon
Published: August 2021

Abstract. The secondary organic aerosol (SOA) formation from photooxidation of gasoline vapor was simulated by using the UNIfied Partitioning Aerosol phase Reaction (UNIPAR) model, which predicted SOA growth via multiphase reactions of hydrocarbons. The Carbon Bond 6 (CB6r3) mechanism was incorporated with the SOA model to estimate the hydrocarbon consumption and the concentration of radicals (i.e., RO2 and HO2), which were closely related to atmospheric aging of gas products. Oxygenated products were lumped according to their volatilities and reactivity and linked to stoichiometric coefficients and their physicochemical parameters, which were dynamically constructed at different NOx levels and degrees of gas aging. To assess the gasoline SOA potential in ambient air, model parameters were corrected for gas–wall partitioning (GWP), which was predicted by a qualitative structure activity relationship for explicit products. The simulated gasoline SOA mass was evaluated against observed data obtained in the UF-APHOR chamber under ambient sunlight. The influence of environmental conditions on gasoline SOA was characterized under varying NOx levels, aerosol acidity, humidity, temperature, and concentrations of aqueous salts and gasoline vapor. Both the measured and simulated gasoline SOA formation was sensitive to seeded conditions (acidity and hygroscopicity) and NOx levels. A considerable difference in SOA mass appeared before and after efflorescence relative humidity in the presence of salted aqueous solution. SOA growth in the presence of aqueous reactions was more impacted by temperature than that in absence of seed. The impact of GWP on SOA formation was generally significant, and it appeared to be higher in the absence of wet salts. We conclude that the SOA model in the corpus with both heterogeneous reactions and the model parameters corrected for GWP is essential to accurately predict SOA mass in ambient air.
Tropospheric ozone changes and ozone sensitivity from present-day to future under shared socio-economic pathways
Authors: Liu Zhenze , Doherty Ruth M. , Wild Oliver , O’Connor Fiona M. , Turnock Steven T.
Published: August 2021

Abstract. Tropospheric ozone is important to future air quality and climate. We investigate ozone changes and ozone sensitivity to changing emissions in the context of climate change from the present day (2004–2014) to the future (2045–2055) under a range of shared socio-economic pathways (SSPs). We apply the United Kingdom Earth System Model, UKESM1, with an extended chemistry scheme including more reactive volatile organic compounds (VOCs) to quantify ozone burdens as well as ozone sensitivities globally and regionally based on nitrogen oxide (NOx) and VOC concentrations. We show that the tropospheric ozone burden increases by 4 % under a development pathway with higher NOx and VOC emissions (SSP3-7.0), but decreases by 7 % under the same pathway if NOx and VOC emissions are reduced (SSP3-7.0-lowNTCF) and by 5 % if atmospheric methane (CH4) concentrations are reduced (SSP3-7.0-lowCH4). Global mean surface ozone concentrations are reduced by 3–5 ppb under SSP3-7.0-lowNTCF and by 2–3 ppb under SSP3-7.0-lowCH4. However, surface ozone changes vary substantially by season in high-emission regions under future pathways, with decreased ozone concentrations in summer and increased ozone concentrations in winter when NOx emissions are reduced. VOC-limited areas are more extensive in winter (7 %) than in summer (3 %) across the globe. North America, Europe and East Asia are the dominant VOC-limited regions in the present day but North America and Europe become more NOx-limited in the future mainly due to reductions in NOx emissions. The impacts of VOC emissions on O3 sensitivity are limited in North America and Europe because reduced anthropogenic VOC emissions are offset by higher biogenic VOC emissions. O3 sensitivity is not greatly influenced by changing CH4 concentrations. South Asia becomes the dominant VOC-limited region under future pathways. We highlight that reductions in NOx emissions are required to transform O3 production from VOC- to NOx-limitation, but that these lead to increased O3 concentrations in high-emission regions, and hence emission controls on VOC and CH4 are also necessary.

Abstract. Plumes from the boreal spring biomass burning (BB) in northern peninsular Southeast Asia (nPSEA) are lifted into the subtropical jet stream and transported and deposited across nPSEA, South China, Taiwan and even the western North Pacific Ocean. This paper as part of the Seven SouthEast Asian Studies (7-SEAS) project effort attempts to improve the chemical weather prediction capability of the Weather Research and Forecasting coupled with the Community Multiscale for Air Quality (WRF–CMAQ) model over a vast region, from the mountainous near-source burning sites at nPSEA to its downwind region. Several sensitivity analyses of plume rise are compared in the paper, and it is discovered that the initial vertical allocation profile of BB plumes and the plume rise module (PLMRIM) are the main reasons causing the inaccuracies of the WRF–CMAQ simulations. The smoldering emission from the Western Regional Air Partnership (WRAP) empirical algorithm included has improved the accuracies of PM10, O3 and CO at the source. The best performance at the downwind sites is achieved with the inline PLMRIM, which accounts for the atmospheric stratification at the mountainous source region with the FINN burning emission dataset. Such a setup greatly improves not only the BB aerosol concentration prediction over near-source and receptor ground-based
measurement sites but also the aerosol vertical distribution and column
aerosol optical depth of the BB aerosol along the transport route. The BB
aerosols from nPSEA are carried by the subtropical westerlies in the free
troposphere to the western North Pacific, while BB aerosol has been found to interact with the local pollutants in the Taiwan region through three conditions: (a) overpassing western Taiwan and entering the central mountain area, (b) mixing down to western Taiwan, (c) transport of local pollutants upwards and mixing with a BB plume on higher ground. The second condition, which involves the prevailing high-pressure system from Asian cold surge, is able to impact most of the population in Taiwan.
Intercomparison of IBBCEAS, NitroMAC and FTIR analyses for HONO, NO2 and CH2O measurements during the reaction of NO2 with H2O vapour in the simulation chamber CESAM

Published: August 2021

Abstract. We report on applications of the ultraviolet-light-emitting-diode-based incoherent broadband cavity-enhanced absorption spectroscopy
(UV-LED-IBBCEAS) technique for optical monitoring of HONO, NO2 and
CH2O in a simulation chamber. Performance intercomparison of
UV-LED-IBBCEAS with a wet chemistry-based NitroMAC sensor and a Fourier transform infrared (FTIR)
spectrometer has been carried out on real-time simultaneous measurement of
HONO, NO2 and CH2O concentrations during the reaction of NO2
with H2O vapour in CESAM (French acronym for Experimental Multiphasic Atmospheric Simulation Chamber). The 1σ
(signal-to-noise ratio (SNR) = 1) detection limits of 112 pptv for NO2, 56 pptv for HONO and 41 ppbv for CH2O over 120 s were found for the UV-LED-IBBCEAS measurement.
On the contrary to many set-ups where cavities are installed outside the
simulation chamber, we describe here an original in situ permanent
installation. The intercomparison results demonstrate that IBBCEAS is a very
well suitable technique for in situ simultaneous measurements of multiple
chemically reactive species with high sensitivity and high precision even if
the absorption bands of these species are overlapped. It offers excellent
capacity for non-invasive optical monitoring of chemical reactions without any
perturbation. For the application to simulation chambers, it has the
advantage to provide a spatially integrated measurement across the reactor
and hence to avoid point-sampling-related artefacts.
A simulation-experiment-based assessment of retrievals of above-cloud temperature and water vapor using a hyperspectral infrared sounder
Authors: Feng Jing , Huang Yi , Qu Zhipeng
Published: August 2021

Abstract. Measuring atmospheric conditions above convective storms using spaceborne instruments is challenging. The operational retrieval framework of current hyperspectral infrared sounders adopts a cloud-clearing scheme that is unreliable in overcast conditions. To overcome this issue, previous studies have developed an optimal estimation method that retrieves the temperature and humidity above high thick clouds by assuming a slab of cloud. In this study, we find that variations in the effective radius and density of cloud ice near the tops of convective clouds lead to non-negligible spectral uncertainties in simulated infrared radiance spectra. These uncertainties cannot be fully eliminated by the slab-cloud assumption. To address this problem, a synergistic retrieval method is developed here. This method retrieves temperature, water vapor, and cloud properties simultaneously by incorporating observations from active sensors in synergy with infrared radiance spectra. A simulation experiment is conducted to evaluate the performance of different retrieval strategies using synthetic radiance data from the Atmospheric Infrared Sounder (AIRS) and cloud data from CloudSat/CALIPSO. In this experiment, we simulate infrared radiance spectra from convective storms through a combination of a numerical weather prediction model and a radiative transfer model. The simulation experiment shows that the synergistic method is advantageous, as it shows high retrieval sensitivity to the temperature and ice water content near the cloud top. The synergistic method more than halves the root-mean-square errors in temperature and column integrated water vapor compared to prior knowledge based on the climatology. It can also improve the quantification of the ice water content and effective radius compared to prior knowledge based on retrievals from active sensors. Our results suggest that existing infrared hyperspectral sounders can detect the spatial distributions of temperature and humidity anomalies above convective storms.
Triple frequency radar retrieval of microphysical properties of snow
Authors: Mroz Kamil , Battaglia Alessandro , Nguyen Cuong , Heymsfield Andrew , Protat Alain , Wolde Mengistu
Published: August 2021

Abstract. An algorithm based on triple-frequency (X, Ka, W) radar measurements that retrieves the size, water content and degree of riming of ice clouds is presented. This study exploits the potential of multi-frequency radar measurements to provide information on bulk snow density that should underpin better estimates of the snow characteristic size and content within the radar volume. The algorithm is based on Bayes' rule with riming parameterized by the “fill-in” model. The radar reflectivities are simulated with a range of scattering models corresponding to realistic snowflake shapes. The algorithm is tested on multi-frequency radar data collected during the ESA-funded Radar Snow Experiment. During this campaign in-situ microphysical probes were mounted on the same airplane as the radars. This nearly perfectly collocated dataset of the remote and in-situ measurements gives an opportunity to derive a combined multi-instrument estimate of snow microphysical properties that is used for a rigorous validation of the radar retrieval. Results suggest that the triple-frequency retrieval performs well in estimating ice water content and mean-mass-weighted diameters obtaining root-mean-square-error of 0.13 and 0.15, respectively for log10 IWC and log10 Dm. The retrieval of the degree of riming is more challenging and only the algorithm that uses Doppler information obtains results that are highly correlated with the in-situ data.

Published: August 2021

Abstract. Experimental watersheds have a long tradition as research sites in hydrology
and have been used since the late nineteenth and early twentieth centuries.
The University of Natural Resources and Life Sciences Vienna (BOKU) recently
extended its experimental research forest site “Rosalia” with an area of 950 ha towards the creation of a full ecological-hydrological experimental
watershed. The overall objective is to implement a multi-scale,
multi-disciplinary observation system that facilitates the study of water,
energy and solute transport processes in the soil–plant–atmosphere
continuum. This article describes the characteristics of the site and the
monitoring network and its instrumentation that has been installed since 2015, as well as
the datasets. The network includes four discharge gauging stations and
seven rain gauges along with observations of air and water temperature,
relative humidity, and electrical conductivity. In four profiles, soil water
content and temperature are recorded at different depths. In addition, since
2018, nitrate, TOC and turbidity have been monitored at one gauging station.
In 2019, a programme to collect isotopic data in precipitation and discharge
was initiated. All data collected since 2015, including, in total, 56 high-resolution time series (with 10 min sampling intervals), are provided to the
scientific community on a publicly accessible repository. The datasets are
available at https://doi.org/10.5281/zenodo.3997140

Published: August 2021

Abstract. In the context of global carbon emission reduction, solar photovoltaics (PV) is experiencing rapid development. Accurate localized PV information, including location and size, is the basis for PV regulation and potential assessment of energy sector. Automatic information extraction based on deep learning requires high-quality labelled samples that should be collected at multiple spatial resolutions and under different backgrounds due to the diversity and variable scale of PV. We established a PV dataset using satellite and aerial images with spatial resolutions of 0.8 m, 0.3 m and 0.1 m, which focus on concentrated PV, distributed ground PV and fine-grained rooftop PV, respectively. The dataset contains 3716 samples of PVs installed on shrub land, grassland, cropland, saline-alkali, and water surface, as well as flat concrete, steel tile, and brick roofs. We used this dataset to examine the model performance of different deep networks on PV segmentation, and on average an intersection over union (IoU) greater than 85 % was achieved. In addition, our experiments show that direct cross application between samples with different resolutions is not feasible, and fine-tuning of the pre-trained deep networks using target samples is necessary. The dataset can support more works on PVs for greater value, such as, developing PV detection algorithm, simulating PV conversion efficiency, and estimating regional PV potential. The dataset is available from Zenodo on the following website: https://doi.org/10.5281/zenodo.5171712 (Jiang et al. 2021).
Quantifying location error to define uncertainty in volcanic mass flow hazard simulations
Authors: Mead Stuart R. , Procter Jonathan , Kereszturi Gabor
Published: August 2021

Abstract. The use of mass flow simulations in volcanic hazard zonation and mapping is often limited by model complexity (i.e. uncertainty in correct values of model parameters), a lack of model uncertainty quantification, and limited approaches to incorporate this uncertainty into hazard maps. When quantified, mass flow simulation errors are typically evaluated on a pixel-pair basis, using the difference between simulated and observed (“actual”) map-cell values to evaluate the performance of a model.
However, these comparisons conflate location and quantification errors,
neglecting possible spatial autocorrelation of evaluated errors. As a
result, model performance assessments typically yield moderate accuracy
values. In this paper, similarly moderate accuracy values were found in a
performance assessment of three depth-averaged numerical models using the
2012 debris avalanche from the Upper Te Maari crater, Tongariro Volcano, as a benchmark. To provide a fairer assessment of performance and evaluate
spatial covariance of errors, we use a fuzzy set approach to indicate the
proximity of similarly valued map cells. This “fuzzification” of simulated results yields improvements in targeted performance metrics relative to a length scale parameter at the expense of decreases in opposing metrics (e.g. fewer false negatives result in more false positives) and a reduction in resolution. The use of this approach to generate hazard zones incorporating the identified uncertainty and associated trade-offs is demonstrated and indicates a potential use for informed stakeholders by reducing the complexity of uncertainty estimation and supporting decision-making from simulated data.
There and back again, an organic carbon journey: mapping pathways and loops
Authors: Scheffold Maike Iris Esther , Hense Inga
Published: August 2021

Abstract. Understanding and determining where organic carbon (OC) ends up in the ocean and how long it remains there is one of the most pressing tasks of our time, as the fate of OC in the ocean links to the climate system. To provide an additional tool to accomplish this and other related tasks, we map and conceptualize OC pathways in a qualitative model. The model is complementary to existing concepts of OC processes and pathways which are based mainly on quantifications and observations of current states and dominant processes. Our model, on the contrary, presents general pathway patterns and embedded processes without focusing on dominant processes or pathways or omitting rare ones. By mapping, comparing, and condensing pathways and involved spatial scales, we define three remineralization and two recalcitrant dissolved organic carbon loops that close within the marine systems. Pathways that exit the marine system comprise inorganic atmospheric, OC atmospheric, and long-term sediment loops. With the defined loops and the embedded process options, the model is flexible and can be adapted to different systems, changing understanding or changing mechanisms. As such, it can help tracking pathway changes and assessing the impact of human interventions on pathways, marine ecosystems, and the oceanic organic carbon cycle.
Seismic radiation from wind turbines: observations and analytical modeling of frequency-dependent amplitude decays

Published: August 2021

Abstract. In this study, we determine spectral characteristics and amplitude decays of
wind turbine induced seismic signals in the far field of a wind farm (WF)
close to Uettingen, Germany. Average power spectral densities (PSDs) are
calculated from 10 min time segments extracted from (up to) 6 months of
continuous recordings at 19 seismic stations, positioned along an 8 km
profile starting from the WF. We identify seven distinct PSD peaks in the
frequency range between 1 and 8 Hz that can be observed to at least 4 km
distance; lower-frequency peaks are detectable up to the end of the profile.
At distances between 300 m and 4 km the PSD amplitude decay can be described by a power law with exponent b. The measured b values exhibit a linear frequency dependence and range from b=0.39 at 1.14 Hz to b=3.93 at 7.6 Hz. In a second step, the seismic radiation and amplitude decays are modeled using an analytical approach that approximates the surface wave field. Since we observe temporally varying phase differences between seismograms recorded directly at the base of the individual wind turbines (WTs), source signal phase information is included in the modeling approach. We show that phase differences between source signals have significant effects on the seismic radiation pattern and amplitude decays. Therefore, we develop a phase shift elimination method to handle the challenge of choosing representative source characteristics as an input for the modeling. To optimize the fitting of modeled and observed amplitude decay curves, we perform a grid search to constrain the two model parameters, i.e., the seismic shear wave velocity and quality factor. The comparison of modeled and observed amplitude decays for the seven prominent frequencies shows very good agreement and allows the constraint of shear velocities and quality factors for a two-layer model of the subsurface. The approach is generalized to predict amplitude decays and radiation patterns for WFs of arbitrary geometry.

The social media marketplace in the ‘quaint’ Creative Writing classroom: Our terms for engagement
Authors: Taylor Suchy Susan
Published: August 2021

In spite of calls for more digital engagement and the fact that students are arriving on campus with digitally connected skills, creative writing classrooms are generally ‘low tech and quaintly humanistic’. We don’t appear to be incorporating the socially networked student experiences in the quaint creative writing classroom. One of the barriers to more engagement may be one of our hard-won ‘markers of professional difference’, that is, the things that distinguish us from other classes. This particular marker is that we are not market-driven. By examining this issue (but not eliminating the marker), we might determine if we can and should open the class up to more engagement. In this paper, the terms ‘social media’ and ‘social media marketplace’ are explored in order to consider changes to the marketplace and some ways to engage with the digital world that honor our traditions and benefit our classrooms by enhancing educational experiences without excessive cost or training.
Staying alive: Contemporary English application of biji
Authors: Drayton Dave
Published: August 2021

This article examines how the ancient tradition of biji notebook writing has been applied and appropriated in the 21st century by authors working in the English language. It traces the journey the biji, a traditional Chinese written form with origins in the third century, has taken and examines how it has been transformed in its contemporary use. Through a critical reading of three such biji collections – Douglas Coupland’s Survivor, a creative non-fiction hybrid that appeared in an anthology of new takes on old forms titled Vikings, Monks, Philosophers, Whores: Old Forms, Unearthed; Owen Kelly’s Sexton Blake & the Virtual Culture of Rosario: A Biji, a fractured academic essay; and Ouyang Yu’s On the Smell of an Oily Rag: Speaking English, thinking Chinese and living Australian, which he defines as biji feixaoshuo or ‘pen-notes non-fiction’ – the evolution of the biji form beyond China will be traced and examined.

While there is distant tradition of biji for these contemporary authors to draw upon, there remain historical, cultural, and/or linguistic barriers between that tradition and their current practice. In this sense, they are pioneers, working to re-establish those characteristics in a radically different written world.
Artes da Existência e as Vidas Infames
Authors: Lorenzetti Collares Regiane , Celestino de França Júnior Luis
Published: August 2021

Este artigo objetiva a partir das considerações de Michel Foucault sobre a dimensão de uma estética da existência relacioná-la às vidas infames, em dois planos que parecem se vincular, a saber, primeiro, de dar destaque às vidas obscurecidas que apenas foram iluminadas quando colocadas como alvos de discursos empreendidos com a finalidade de classificação, controle e exclusão; segundo, da possibilidade de experiências transformadoras no que diz respeito às subjetividades marginalizadas. Examinaremos então em que medida a pesquisa foucaultiana portaria a virtualidade de um deslocamento a um só tempo estético e ético, da modificação de um modo de vida, de um estilo de existência. Uma vez reconhecendo a dimensão estética em Foucault vinculada à arte de existir, pretendemos então tecer um texto que também se componha com as considerações do filósofo da estética Étienne Souriau, apresentadas no livro As Existências Mínimas, por David Lapoujade, no sentido de que os dois pensadores franceses parecem confluir na mesma direção no que liga a arte às transformações de si, isto é, ambos elaboram uma compreensão da estética interseccionada aos modos de existência, buscando tematizar de que modo as vidas que mesmo privadas do direito de existir, podem ainda encontrar espaços de criação e transformação.
Poética do Waka:
Authors: Cesar Porto da Silva Diogo
Published: August 2021

O artigo se propõe a uma investigação da potência filosófica presente na poesia japonesa clássica conhecida como waka. O aspecto formal mais proeminente do waka é a sua curta estrutura composta geralmente de 31 sílabas moraicas divididas, respectivamente, em 5 versos de 5, 7, 5, 7 e 7 sílabas cada. Para erguer-se como uma forma poética, o waka emprega o recurso rítmico da pausa e uma retórica que vinculam cada poema individual ao todo da tradição através de precedentes. Defendemos que na tradição intelectual constituída pelo waka há uma filosofia do real – que denominamos intertextualidade do real – que entende a realidade como vazia e impermanente. Dessa forma, seria o waka a forma mais adequada através da qual exprimir o real uma vez que ele é mais profundo e excelente a medida em que cria um movimento de esvaziamento e tornar impermanente através de seus recursos formais e retóricos: seu cerne, sua disposição e significado (nossas traduções do termo japonês “kokoro”) e suas palavras (“kotoba”).
