Antiracist Medievalisms
Authors: Hsy Jonathan
Published: October 2022

How do marginalized communities across the globe use the medieval past to combat racism, educate the public, and create a just world? Jonathan Hsy advances urgent academic and public conversations about race and appropriations of the medieval past in popular culture and the arts.

Examining poetry, fiction, journalism, and performances, Hsy shows how cultural icons such as Frederick Douglass, Wong Chin Foo, Alice Dunbar-Nelson, and Sui Sin Far reinvented medieval traditions to promote social change. Contemporary Asian, Black, Indigenous, Latinx, and multiracial artists embrace diverse pasts to build better futures.

“Makes the crucial move of tying medievalism studies readings to social and racial justice work explicitly … innovative and greatly needed in the field.” Seeta Chaganti, author of Strange Footing

“A major accomplishment that belongs on the shelves of every person who believes in antiracism.” Geraldine Heng, author of The Invention of Race in the European Middle Ages
Effects of small-sided games on technical-tactical actions and physical performance in handball: a systematic review
Authors: Dechechi Clodoaldo José , Aquino Rodrigo , Monezes Rafael Pombo , Puggina Enrico Fuini
Published: October 2022

Purpose.

This systematic review aimed to investigate the acute and chronic effects of the task constraints of small-sided games on technical-tactical, physical, and physiological indicators in handball players.

Methods.

A systematic literature search was performed between 2000 and 2020 in SciELO, ISI Web of Science, SPORTDiscus by EBSCOhost, Medline, Redalyc, and Scopus. Studies in female and male youth and adult handball players which involved acute and chronic effects of small-sided games on technical-tactical, physical, and physiological indicators were considered. Methodological quality was determined for the included studies.

Results.

Altogether, 20 studies were included; 91% were published since 2014. The studies presented a mean of 80% in terms of methodological quality. Seven articles (35%) had a mean of 75% or less, and 13 articles (65%) had a mean above 75%. Decreasing on pitch area increased the total distance covered, while the smaller player format promoted increasing the total distance covered and time in sprints. Additionally, the time above 90% of the relative heart rate increased concomitantly with the player format increase.

Conclusions.

The greater individual playing area (i.e., the pitch area divided by the number of players) resulted in higher values of total distance covered. The results identified gaps in the knowledge on the effects of task constraints on collective dynamic and tactical behaviour in handball players to be analysed in further studies.
Feminist Nomads: The Politics of Walking in Agnès Varda
Authors: Özgen Asli
Published: October 2022

Moving the focus to the insurgent social movements of May ’68, this
chapter investigates how walking, wandering, or marching changed its
on-screen meaning in the French Nouvelle Vague. Arguing against the
male-dominant historiography of this period, it analyses the articulation
of dissent through walking in Agnès Varda’s filmography. Through the
analysis of three films—Cleo de 5 à 7 (Cleo from 5 to 7, 1962), Sans toit ni loi
(Vagabond, 1985), and Les plages d’Agnès (The Beaches of Agnès, 2008)—the
chapter explores feminist aesthetics and cinematic pedestrianism as a
dissentient tactic. The chapter argues that the cinematic pedestrianism of
women protagonists in these films embodies the feminist intersectional
repertoire of activism, such as walking and marching in the city, to challenge
gendered and heteronormative constructions of space.

Published: October 2022

Objective-Psychological Indicator specifies impetus and drift way, in addition to overbought and overvalued worth echelons and its conforming conceivable mean setbacks. These indicators play an essential role in sustainable development goals via stock market activities. The central objectives of the study are to identify the key psychological cognitive indicators behind the abnormal movements of the market.
Methodology -For this purpose, a Semi-structured scale - developed on a self-basis - (with the help of literature and connoisseur’s meetings) was used after the context and the content validity to get an extensive array of differentiated information.
Results-According to the experts of the market: investors do not always behave rationally, most investors either fall in the category of overconfident investors or status quo investors, usually the Rookies or beginners in the stock markets only have elementary knowledge and basic experience in the investment domain, based on little or no knowledge of rookies it is actually so hard for them to recognize the future prospects of the securities, and not only investors but stock market’s financial analysts can also be subjected to the behavioral biases but on the other hand in order to understand and recognize one’s own behavioral biases and proneness towards those biases investors can rely on financial planners.
Conclusion-The traditional economic theory states that the investor is rational: which is not true in every case and is hard to generalize. Investors must overcome the general predispositions that lead to poor decision-making if they are to become successful in the stock market in the long run. And the investor must learn all about the investment accounts available in the stock market
Impact of Brand Image on Green Purchase Intentions: Mediating Role of CSR Perceptions
Authors: Zara sabeen  , Faria Arshad  , Neelam Ayub
Published: October 2022

Nowadays, green consumerism is becoming the center of attraction for many researchers. The dominance of environment-friendly consumers is increasing. In the context of Pakistan, this research issue is not fully explored, and the hospitality industry of Pakistan remains unexplored concerning the green purchase intention to the best of the researcher’s knowledge. It is also identified that the concept of green purchase is a relatively untouched area in the service industry overall. Therefore, current research aims to investigate the association of the brand image with purchasing intentions of green consumers, in the presence of the mediating effect of CSR. This study has collected quantitative data where customers from the hospitality industry are selected. The sample size of the returned questionnaires on which the findings of the study have been based is 246. The findings of the study state that the role of brand image in green purchase intention is extensive. Further investigation of the mediating role of CSR indicates a partial mediation of CSR perception between the brand image and green purchase intentions of consumers. Hence, it can be significantly stated from the findings of the current research that the positive CSR perception is expected to play a complementary role in the overall green purchase intentions of consumers in the hospitality sector of Pakistan. The recommendations for future research state the need for further industry perspectives to be explored in terms of CSR implications.

Determining functional movement screen normative values as a predictor of injury in triathletes
Authors:   , Jacobs Izanne
Published: October 2022

Triathlon is a multidisciplinary sport that comprises of swimming, cycling and running. Triathlon events are classified as sprint distance, Olympic distance and Ironman or long course triathlons. Triathlon is considered to be one of the fastest growing sports globally and, despite this, there is insufficient data relating to injuries and injury prevention in the South African context. The Functional Movement Screen™ is a pre-participation screening tool that evaluates fundamental movement patterns to determine potential injury risk and to predict injury. Aim: This study aims to determine the normative values for the FMS™ in triathletes and its ability to identify possible injury risks in triathletes. Methods: The research evaluated the FMSTM score in triathletes in the eThekwini municipal area prior to the commencement of a training session and then tracked the incidence, frequency and distribution of injuries that were sustained during a six-week follow-up period. Two triathlon training groups were approached, and triathletes voluntarily participated provided that they fitted the inclusion criteria. The triathletes were required to fill out an athlete questionnaire which was followed by performing the seven FMS™ tests. In total 24 triathletes between the ages of 18 and 35 were assessed. IBM SPSS version 27 was used in the data analysis to test for statistical significance of the results. Results: The research sample revealed that the normative value for the FMS™ score for triathletes was 14.25 out of 21, with a standard deviation of 2.15. The male triathletes (14.32), on average, had a higher FMS™ score than the female triathletes (14.00). The participants did not report any injuries during the six weeks after completing the FMS™, therefore, this research shows that no association can be made between a low score on the Functional Movement Screen TM and injury susceptibility. There was, however, noted that triathletes who reported current injuries scored lower on the FMS™ (13.25) than triathletes who did not report current injuries (14.45). However, this finding was not statistically significant (p=0.319). Further findings suggested that the most common injuries amongst triathletes were lower extremity muscle strains. Conclusion: The results concur with previous research. However, this study adds insight into injury occurrence and prevention strategies in triathlon. The most common injuries require investigation to develop preventative interventions to reduce injuries in triathletes. Health professionals require education about triathlon-related injuries to improve preventative and curative intervention

One particular phenomenon in this research is that the Bonded Zone facility policy has its own appeal in the producers' eyes on an export basis. Consequently, judging from the large number of Bonded Zone scattered throughout Bekasi City, it becomes a significant obstacle for the supervisory duty’s implementation. The number of personnel within the Directorate General of Customs and Excise (DJBC) is inadequate, which in turn, causes the practice of misusing DJBC's superior facilities is easier to do. This study aims to determine and analyze the Bonded Zone facility policy supervision for importers at the supervision and Service Office for Customs and Excise in Type A of Bekasi Customs and Excise and the constrictions and efforts in the supervision process. The research method employed was descriptive research with a qualitative approach. Meanwhile, the data analysis method implemented was qualitative data analysis. The results of this study indicated that the policy supervision of Bonded Zone facility for importers at KPPBC TMP A Bekasi has been going well on each year. However, it has not been optimally implemented. It is indicated by the findings from the inspection results and action carried out by KPPBC TMP A Bekasi. In implementing the bonded area facility policy supervision, KPPBC TMP A Bekasi tackled various obstacles, nearly data retrieval problems on the CEISA TPB application, the unmatched company IT Inventory to what was reported, and the insufficient number of personnel in the supervisory unit.

on climate radiative forcing. This study investigates the coupled effects of
pH and particle size on the chemical structures (functional groups) and
optical properties (UV/fluorescence properties) of WSOC and further
explores the source and aging of WSOC constituents. The results showed that
the specific UV absorbance at a wavelength of 254 nm (SUVA254) and mass
absorption efficiency at a wavelength of 365 nm (MAE365) were higher in
smaller than larger particles, revealing the relatively higher
aromaticity/molecular weight and more freshness of WSOC in smaller
particles. A decrease in aromaticity/molecular weight of WSOC in larger
particles was caused by the degradation reaction that occurred during the
aging process. The carboxylic groups tend to be enriched in larger
particles, whereas the contribution of phenolic groups was generally higher
in smaller particles. The changes in the fluorescence peak position
suggested that hydroxyl groups play a leading role in pH-responsive
fluorescence in summer, while carboxylic and nitro groups play a dominant
role in winter. Overall, the chromophores in smaller particles showed a more
pronounced pH dependence, which might be related to the higher content of
aromatic species in WSOC in these particle size ranges. Specifically, the
climate impact of WSOC would be enhanced with increasing pH. The pH- and
particle-size-dependent chemical and optical properties of WSOC provide
insights into the structure, source, and aging of WSOC, which will
ultimately improve the accuracy of assessing the climate effects of WSOC.

Abstract. There are plenty of monitoring methods to quantify gas emission rates based on gas concentration measurements around the strong sources. However,
there is a lack of quantitative models to evaluate methane emission rates from coal mines with less prior information. In this study, we develop a
genetic algorithm–interior point penalty function (GA-IPPF) model to
calculate the emission rates of large point sources of CH4 based on concentration samples. This model can provide optimized dispersion parameters and self-calibration, thus lowering the requirements for auxiliary data accuracy. During the Carbon Dioxide and Methane Mission (CoMet) pre-campaign, we retrieve CH4-emission rates from a ventilation shaft in Pniówek coal mine (Silesia coal mining region, Poland) based on the data collected by an unmanned aerial vehicle (UAV)-based AirCore system and a GA-IPPF model. The concerned CH4-emission rates are variable even on a single day, ranging from 621.3 ± 19.8 to 1452.4 ± 60.5 kg h−1 on 18 August 2017 and from
348.4 ± 12.1 to 1478.4 ± 50.3 kg h−1 on 21 August 2017. Results
show that CH4 concentration data reconstructed by the retrieved parameters are highly consistent with the measured ones. Meanwhile, we
demonstrate the application of GA-IPPF in three gas control release experiments, and the accuracies of retrieved gas emission rates are better
than 95.0 %. This study indicates that the GA-IPPF model can quantify the CH4-emission rates from strong point sources with high accuracy.

Abstract. Cloud processing is known to generate aerosol species such as sulfate and secondary organic aerosol, yet there is a scarcity of airborne data to
examine this issue. The NASA Aerosol Cloud meTeorology Interactions oVer the western ATlantic Experiment (ACTIVATE) was designed to build an
unprecedented dataset relevant to aerosol–cloud interactions with two coordinated aircraft over the northwestern Atlantic, with aerosol mass spectrometer data used from four deployments between 2020–2021 to contrast aerosol composition below, in (using a counterflow virtual impactor)
and above boundary layer clouds. Consistent features in all time periods of the deployments (January–March, May–June, August–September) include
the mass fraction of organics and relative amount of oxygenated organics (m/z 44) relative to total organics (f44) increasing in droplet
residuals relative to below and above cloud. Detailed analysis comparing data below and in cloud suggests a possible role for in-cloud aqueous
processing in explaining such results; an intriguing aspect though requiring more attention is that only approximately a quarter of the cloud
cases (29 of 110) showed higher organic mass fractions either below or above cloud. Of those 29 cases, the majority (25) showed higher organic mass
fraction below cloud base where the cloud processing signature is presumably more evident as compared to above cloud. These results are consistent
with the few past studies analyzing droplet residuals pointing to higher organic enrichment than in adjacent cloud-free areas. The data findings are
important as other datasets (e.g., reanalysis) suggest that sulfate is both more abundant than organics (in contrast to this work) and more closely
related to drop number concentrations in the winter when aerosol–cloud interactions are strongest. Here we show that organics are more abundant than
sulfate in the droplet residuals and that aerosol interaction with clouds potentially decreases particle hygroscopicity due to the increase in
organic:sulfate ratio for droplet residuals relative to surrounding cloud-free air. These results are important in light of the growing importance
of organics over the northwestern Atlantic in recent decades relative to sulfate owing to the success of regulatory activity over the eastern United States to cut sulfur dioxide emissions.
Estimation of refractivity uncertainties and vertical error correlations in collocated radio occultations, radiosondes, and model forecasts
Authors: Nielsen Johannes K. , Gleisner Hans , Syndergaard Stig , Lauritsen Kent B.
Published: October 2022

Abstract. Random uncertainties and vertical error correlations are estimated for
three independent data sets. The three collocated data sets are
(1) refractivity profiles of radio occultation measurements retrieved
from the Metop-A and B and COSMIC-1 missions, (2) refractivity derived
from GRUAN-processed RS92 sondes, and (3) refractivity profiles derived
from ERA5 forecast fields. The analysis is performed using
a generalization of the so-called three-cornered hat method to include
off-diagonal elements such that full error covariance matrices can be
calculated. The impacts from various sources of representativeness
error on the uncertainty estimates are analysed. The estimated
refractivity uncertainties of radio occultations, radiosondes, and
model data are stated with reference to the vertical representation of
refractivity in these data sets. The existing theoretical estimates of
radio occultation uncertainty are confirmed in the middle and upper
troposphere and lower stratosphere, and only little dependence on
latitude is found in that region. In the lower troposphere,
refractivity uncertainty decreases with latitude. These findings have
implications for both retrieval of tropospheric humidity from radio
occultations and for assimilation of radio occultation data in numerical weather prediction models and reanalyses.

Abstract. New global nitric oxide (NO) volume mixing ratio and lower thermospheric temperature data products, retrieved from Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) spectra with the IMK-IAA MIPAS data processor, have been released. The dataset covers the entire Envisat mission lifetime and includes retrieval results from all MIPAS observation modes. The data are based on ESA version 8 calibration and were processed using an improved retrieval approach compared to previous versions, specifically regarding the choice and construction of the a priori and atmospheric parameter profiles, the treatment of horizontal inhomogeneities, the treatment of the radiance offset correction, and the selection of optimized numerical settings. NO retrieval errors of individual observations are dominated by measurement noise and range from 5 % to 50 % in the stratosphere and thermosphere, and reach 40 % to 90 % in the mesosphere. Systematic errors are typically within 10–30 %. Lower thermospheric temperature errors are 5 K to 50 K with a systematic component of around 10K, the latter being dominated by non-LTE related uncertainties. NO data from different observation modes are consistent within 5–10 %. MIPAS version 8 temperatures have a better representation of the diurnal tide in the lower thermosphere compared to previous data versions. The new MIPAS temperatures are systematically warmer than results from the empirical NLRMSIS2.0 model by 30 K to 80 K in the 100–120 km region, and are colder above.
Colombian soil texture: building a spatial ensemble model

Published: October 2022

Abstract. Texture is a fundamental soil property for multiple applications in environmental and earth sciences. Knowing its spatial distribution allows a better understanding of the response of soil conditions to changes in the environment, such as land use. This paper describes the technical development of Colombia's first texture maps, obtained via a spatial ensemble of national and global digital soil mapping products. This work compiles a new database with 4203 soil profiles, which were harmonized at five standard depths (0–5, 5–15, 15–30, 30–60, and 60–100 cm) and standardized with additive log ratio (ALR) transformation. A compilation of 83 covariates was developed and harmonized at 1 km2 of spatial resolution. Ensemble machine learning (EML) algorithms (MACHISPLIN and landmap) were trained to predict the distribution of soil particle size fractions (PSFs) (clay, sand, and silt), and a comparison with SoilGrids (SG) products was performed. Finally, a spatial ensemble function was created to identify the smallest prediction errors between EML and SG. Our results are the first effort to build a national texture map (clay, sand, and silt fractions) based on digital soil mapping in Colombia. The results of EML algorithms showed that their accuracies were very similar at each standard depth, and were more accurate than SG. The largest improvement with the spatial ensemble was found at the first layer (0–5 cm). EML predictions were frequently selected for each PSF and depth in the total area; however, SG predictions were better when increasing soil depth in some specific regions. The final error distribution in the study area showed that sand presented higher absolute error values than clay and silt fractions, specifically in eastern Colombia. The spatial distribution of soil texture in Colombia is a potential tool to provide information for water-related applications, ecosystem services, and agricultural and crop modeling. However, future efforts need to improve aspects such as treating abrupt changes in the texture between depths and unbalanced data. Our results and the compiled database (https://doi.org/10.6073/pasta/3f91778c2f6ad46c3cc70b61f02532db, Varón-Ramírez and Araujo-Carrillo, 2022, https://doi.org/10.6073/pasta/d6c0bf5847aa40836b42dcc3e0ea874e, Varón-Ramírez et al., 2022) provide new insights to solve some of the aforementioned issues.
