Street Art on TikTok: Engaging with Digital Cosmopolitanism
Authors: Shen Zheng
Published: December 2022

Under the influence of social media, aesthetic cosmopolitans have shifted from the real world to the digital world. This study exemplified Jingxuan Peng’s street art on TikTok to explore how street artists digitally increase the transcultural engagement with the cosmopolitan community on social media. As a result, a total of 243 videos and corresponding engagement responses were collected and investigated through text mining analysis. Overall, street art in these short videos was classified as fully exotic, partly exotic, and a combination of local and exotic art, and the study finds that the last category has the highest level of engagement in the digital cosmopolitan community. In conclusion, this study fills a gap in the limited analysis of street art and digital cosmopolitism on social media, and provides managerial insights for street artists and art appreciation in the age of Internet.
Driving mechanisms for the El Niño–Southern Oscillation impact on stratospheric ozone
Authors: Benito-Barca Samuel , Calvo Natalia , Abalos Marta
Published: December 2022

Abstract. While the impact of the El Niño–Southern Oscillation
(ENSO) on the stratospheric circulation has been long recognized, its
effects on stratospheric ozone have been less investigated. In particular,
the impact on ozone of different ENSO flavors, eastern Pacific (EP) El
Niño and central Pacific (CP) El Niño, and the driving
mechanisms for the ozone variations have not been investigated to date. This
study aims to explore these open questions by examining the anomalies in
advective transport, mixing and chemistry associated with different El
Niño flavors (EP and CP) and La Niña in the Northern Hemisphere in
boreal winter. For this purpose, we use four 60-year ensemble members of the
Whole Atmospheric Community Climate Model version 4. The results show a
significant ENSO signal on the total column ozone (TCO) during EP El Niño
and La Niña events. During EP El Niño events, TCO is significantly
reduced in the tropics and enhanced at middle and high latitudes in boreal
winter. The opposite response has been found during La Niña.
Interestingly, CP El Niño has no significant impact on extratropical TCO,
while its signal in the tropics is weaker than for EP El Niño events.
The analysis of mechanisms reveals that advection through changes in
tropical upwelling is the main driver for ozone variations in the lower
tropical stratosphere, with a contribution of chemical processes above 30 hPa. At middle and high latitudes, stratospheric ozone variations related to
ENSO result from combined changes in advection by residual circulation
downwelling and changes in horizontal mixing linked to Rossby wave breaking
and polar vortex anomalies. The impact of CP El Niño on the shallow
branch of the residual circulation is small, and no significant impact is
found on the deep branch.

Abstract. Atmospheric carbon dioxide (CO2) accounts for the largest radiative forcing among anthropogenic greenhouse gases. There is, therefore, a pressing need to understand the rate at which CO2 accumulates in the atmosphere, including the interannual variations (IAV) in this rate. IAV in the CO2 growth rate is a small signal relative to the long-term trend and the mean annual cycle of atmospheric CO2, and IAV is tied to climatic variations that may provide insights into long-term carbon-climate feedbacks. Observations from the Orbiting Carbon Observatory-2 (OCO-2) mission offer a new opportunity to refine our understanding of atmospheric CO2 IAV since the satellite can measure over remote terrestrial regions and the open ocean where traditional in situ CO2 monitoring is difficult. In this study, we analyze the IAV of column-averaged dry air CO2 mole fraction (XCO2) from OCO-2 between September 2014 to June 2021. The amplitude of IAV variations is up to 1.2 ppm over the continents and around 0.4 ppm over the open ocean. Across all latitudes, the OCO-2 detected XCO2 IAV shows a clear relationship with ENSO-driven variations that originate in the tropics and are transported poleward. The XCO2 IAV timeseries shows similar zonal patterns compared to ground-based in situ observations and with column observations from the Total Carbon Column Observing Network (TCCON). At lower degrees of aggregation (i.e., 5°x5° grid cells), there are larger inconsistencies with TCCON suggesting that one or both of the observing systems are affected by bias or systematic retrieval issues that are of a similar magnitude to the IAV signal. Our results suggest that OCO-2 IAV provides meaningful information about climate-driven variations in carbon fluxes and provides new opportunities to monitor climate-driven variations in CO2 over open ocean and remote regions.
Assimilation sensitivity of satellite-derived surface melt into the Regional Climate Model MAR: case study over the Antarctic Peninsula

Published: December 2022

Abstract. The study of the recent variability and the future projections of the poles’ climate currently relies on polar-oriented Regional Climate Models (RCMs). However, RCMs are subject to biases and systematic errors that impact the results of their simulations. Remote Sensing (RS) data can help to reduce these ambiguities by providing indirect observations to the modeled estimates. Using the behavior of radiofrequency signals with regard to the presence of water in a snowpack, passive and active microwave instruments such as AMSR2, ASCAT, and Sentinel-1 are used to detect melt at the surface of the snowpack. In this paper, we investigate the sensitivity of the RCM “Modèle Atmosphérique Régional” (MAR) to the assimilation of surface melt occurrence estimated by RS datasets. The assimilation is performed by nudging the MAR snowpack temperature to match the observed melt state by satellite. The sensitivity is tested by modifying parameters of the assimilation: (i) the depth to which MAR snowpack is warmed up or cooled down (corresponding to the penetration depth of the satellites) to match with satellite, and (ii) the quantity of water required into the snowpack to qualify a MAR pixel as melting or not, and (iii) by assimilating multiple RS datasets. The data assimilation is performed over the Antarctic Peninsula for the 2019-2021 period. The results show an increase in the melt production (+66.7 % on average, or +95 Gt) going along with a small decrease in surface mass balance (SMB) (-4.5 % on average, or -20 Gt) for the 2019–2020 melt season. The model is sensitive to the three parameters tested but with different orders of magnitude. The sensitivity to the assimilated dataset is reduced by using multiple datasets during the assimilation and discarding the remote observations that are not coherent. For the other two parameters, the penetration depth has more impact on the assimilation than the quantity of liquid water used as melt threshold. The first one is especially sensitive for the sensors with a shorter penetration depth. In the first centimeters, a densification due to a refreeze can impact the melt production and cause an overestimation of the melt production. For the second threshold, the impact is more important on the number of melt days rather than the melt production itself. The values tested for the quantity of liquid water required into the snowpack to qualify a MAR pixel as melting or not (0.1 or 0.2 % of the snowpack mass being water) are lower than during typical melt days (~1.2 %) and impact results mainly at the beginning and end of the melt period when lower values are reached. Such an assimilation will allow an uncertainty estimation of MAR’s melt production, as well as identifying potential issues at the snowpack surface processes.
Interannual to decadal sea level variability in the subpolar North Atlantic: the role of propagating signals
Authors: Volkov Denis L. , Schmid Claudia , Chomiak Leah , Germineaud Cyril , Dong Shenfu , Goes Marlos
Published: December 2022

Abstract. The gyre-scale, dynamic sea surface height (SSH) variability
signifies the spatial redistribution of heat and freshwater in the ocean,
influencing the ocean circulation, weather, climate, sea level, and
ecosystems. It is known that the first empirical orthogonal function (EOF)
mode of the interannual SSH variability in the North Atlantic exhibits a
tripole gyre pattern, with the subtropical gyre varying out of phase with
both the subpolar gyre and the tropics, influenced by the low-frequency
North Atlantic Oscillation. Here, we show that the first EOF mode explains
the majority (60 %–90 %) of the interannual SSH variance in the Labrador and
Irminger Sea, whereas the second EOF mode is more influential in the
northeastern part of the subpolar North Atlantic (SPNA), explaining up to
60 %–80 % of the regional interannual SSH variability. We find that the two
leading modes do not represent physically independent phenomena. On the
contrary, they evolve as a quadrature pair associated with a propagation of
SSH anomalies from the eastern to the western SPNA. This is confirmed by the
complex EOF analysis, which can detect propagating (as opposed to
stationary) signals. The analysis shows that it takes about 2 years for sea
level signals to propagate from the Iceland Basin to the Labrador Sea, and
it takes 7–10 years for the entire cycle of the North Atlantic SSH tripole
to complete. The observed westward propagation of SSH anomalies is linked to
shifting wind forcing patterns and to the cyclonic pattern of the mean ocean
circulation in the SPNA. The analysis of regional surface buoyancy fluxes in
combination with the upper-ocean temperature and salinity changes suggests a
time-dependent dominance of either air–sea heat fluxes or advection in
driving the observed SSH tendencies, while the contribution of surface
freshwater fluxes (precipitation and evaporation) is negligible. We
demonstrate that the most recent cooling and freshening observed in the SPNA
since about 2010 were mostly driven by advection associated with the North
Atlantic Current. The results of this study indicate that signal propagation
is an important component of the North Atlantic SSH tripole, as it applies
to the SPNA.

After-School Connectedness, Racial–Ethnic Identity, Affirmation, and Problem Behaviors
Authors: Augustine Danielle A. , Smith Emilie P. , Witherspoon Dawn P.
Published: December 2022

After-school programs are potential contexts that may promote positive youth development (PYD) and reduce problem behaviors among African American children. One way after-school programs may be associated with reduced problem behaviors is by fostering an affirming sense of identity. Prior research on racial–ethnic identity among African American children and adolescents has shown that a positive and affirming sense of identity is related to less maladaptive coping, yet little is known about how after-school programs may foster an affirming sense of identity and lead to reduced problem behaviors. The current study adds to this discourse by investigating how children’s connection to staff and peers in after-school settings is associated with racial–ethnic identity (as measured by racial–ethnic affirmation) and reduced problem behaviors. Participants were 186 African American children ages 7–11 (M = 8.44; SD = 1.10) who completed surveys in the LEGACY Together Afterschool research project. Data were collected at 55 community-based after-school programs. Results indicated that positive racial–ethnic affirmation mediated the association between after-school connectedness and problem behaviors, such that child-report of connectedness—that is feeling safe and happy in the after-school programs—was directly related to positive racial–ethnic identity and indirectly to reduced problem behaviors. These findings underscore the importance of supportive after-school programs that encourage meaningful interactions among staff and children that are nurturing and affirming to children’s identities.
Taking New Directions: How Rural Queerness Provides Unique Insights into Place, Class, and Visibility
Authors: Baker Kelly
Published: December 2022

In this paper I demonstrate how an attention to rural queerness offers a beneficial and necessary opportunity to examine queer subjectivies through the lens of space, place, and class. I highlight how individuals' claims to queerness can actually be embeddd within identifications with class and place. I demonstrate how identifications with place are illustrative of a broader coneption of rurality, an often-ignored yet immensely pervasive thread of identity, which, governed by familiarity, familial affiliation, and community participation, can actually provide rural queer individuals with a means of both acceptance and queer expression alternative to dominant models. I illustrate how rurality is not only absent from hegemonic urban conceptualizations of queer visibility, but is actually incompatible with the basic tenets of mainstream urban queer visibility politics. Rurality thus provides a compelling vehicle of critique and alternative envisioning for contemporary queer politics and subjectivities.
Behavioural Changes in Parenting Female Mantled Howler Monkeys (Alouatta palliata)
Authors: Cancelliere Emma
Published: December 2022

Parenting in mantled howler monkeys (Alouatta palliata) requires a new set of energetic and behavioural demands. Because of constraints presented by the infant, as well as the increased energy requirements associated with mothering, parenting females need to change their activity patterns to ensure the successful upbringing of their offspring. This study of wild mantled howler monkeys was conducted to examine differences in activity between parenting and non-parenting adult females. Twenty two hours of continuous sampling on focal individuals was collected over the course of ten days in August at a study site in Nicaragua. It was found that the two groups do differ in their activity patterns: parenting females spent a larger percent of their time resting, feeding and interacting, but a lower percent of their time travelling when compared to non-parenting females. Further, it was found that parenting females engaged in scanning behaviours more frequently, and engaged in bridging (a locomotor behaviour) less frequently. These results suggest that parenting female mantled howler monkeys adopt an energy-minimizing activity pattern wherein the mothers compensate for their increased energetic requirements by only slightly increasing their food intake and instead drastically increasing the amount of time spent resting.
La felicidad, los remordimientos y el poder punitivo del estado: ¿es el Anti–Sénèque de La Mettrie un proyecto trunco?
Authors: Ratto Adrián
Published: December 2022

La Mettrie parece rechazar completamente la filosofía de Séneca en su Anti-Sénèque. El objetivo de este artículo es demostrar que una lectura más atenta del texto muestra que su posición es menos simple de lo que puede parecer en un primer momento. En otras palabras, se intenta exponer los límites de los cuestionamientos que el médico de Saint-Malo dirige a la filosofía y la imagen del filósofo romano. El trabajo, por otra parte, pone de relieve ciertas tensiones que atraviesan el escrito y amenazan el propósito que La Mettrie se había propuesto, a saber, mejorar la vida de los hombres.
The Impact of Nuclear Energy Consumption on Economic Growth and CO2 Emissions in Selected Asian Economies
Authors: Batool Komal , Akbar Muhammad
Published: December 2022

Most countries' economic policies aim towards long-term growth in the economy. The economic growth has an effect on global warming and climate change, which are two of the biggest problems and worries in the world. Because of economic growth and civilization, the amount of carbon dioxide (CO2) and other greenhouse gases (GHG) in the air has gone up. In order to do this, the study used the Dumitrescu and Hurlin (D-H) and Common Correlated Effect Mean Group (CCE-MG) causality tests to look at how nuclear energy affected economic growth in some Asian countries from 1990 to 2017. The results of CCE-MG showed that developing countries in Asia used less renewable energy and nuclear energy than they thought they would. On the other side, the use of non-renewable energy had the negative effect on economic growth. Further, it was observed that the renewable energy had a positive effect on the amount of CO2 released in developing countries. Based on the results, the study suggested that the government and policymakers should focus on renewable energy sources to help them grow while at the same time putting in place environmental rules to protect the environment.
Auto-organização nos manuais do cinema silencioso
Authors: D'Urso Hebling Eduardo , Manzolli Jônatas
Published: December 2022

Nos seus primórdios, os filmes silenciosos eram exibidos em diversos locais e com diversos modos de acompanhamento, como leitores, dubladores de diálogos e sons, gramofones e música. Ao eleger as pequenas salas chamadas nickelodeon como local de exibição, a disparidade desses modos gerou uma crise. Estudos apontam para uma campanha de padronização cogitada pelos produtores de filmes, por meio de uma farta literatura normativa, mas qual teria sido o papel dos músicos nesse processo? Para delinear esse papel, fizemos uma análise de conteúdo dos manuais técnico-normativos do período. Discutimos os resultados usando os conceitos de mundos da arte de Becker e da historiografia de crise de Altman, mas a complexidade deste sistema dinâmico nos aproximou da auto-organização de Ashby e Foerster, comentados por Heylighen, e da complexidade de Morin. Concluímos que os músicos, alimentados pela improvisação e adaptação das performances, foram agentes criativos e informacionais na auto-organização dessa arte.

Mineral association in pegmatites from the Djurkovo Pb-Zn deposit, Central Rhodopes: preliminary results
Authors: Georgieva Sylvina , Vassileva Rossitsa , Milenkov Georgi
Published: December 2022

Deformed pegmatites of varying thickness and position are a significant constituent intruded in the metamorphic complex, hosting the Djurkovo Pb-Zn deposit in Central Rhodopes. The mineral composition of the pegmatites consists of plagioclase, K-feldspar, quartz, and minor micas. The main accessory minerals are allanite, titanite, apatite and zircon. Late hydrothermal alteration of pegmatites led to the formation of epidote, adularia, sericite, chlorite, carbonate, quartz and leucoxene. Rare earth carbonate-phosphate assemblage (REE+Y, Th, U), manifested as ˂ 20 µm anhedral grains, is observed along fractures and dissolved zones in allanite and titanite. Because of the limited mobility of REE in fluids, these elements are barely transported during the hydrothermal activity and are incorporated in new phases, precipitated in the frames of the altered accessory minerals. The studied pegmatites contain a significant amount of accessory minerals rich in incompatible elements and therefore could be considered as their potential source.

Published: December 2022

This study aims at investigating the effect of digital HRM practices on employee motivation and hence employee job performance, or in other words, the mediating role of employee motivation between digital HRM practices and employee job performance. Two digital HRM practices were used in this study: digital training and digital performance appraisal. Collecting data using a valid and reliable questionnaire from employees at industrial companies, the results show that digital training had significant effects on both employee motivation and job performance, digital performance appraisal had significant effects on employee motivation and performance appraisal, and employee motivation exerted a significant effect on job performance. Consequently, it was approved that employee motivation partially mediated the effect of digital HRM practices on job performance. It was concluded that skilled employees who are aware of their performance level are motivated to show higher levels of job performance. Theoretically, the study called scholars to carry out further results to examine the effects of other HRM practices on job performance through employee motivation. Empirically, organizations are requested to conduct training sessions and assess employee performance using digital means.

Published: December 2022

In keeping abreast with the digitized and automated world today, governments of developing and developed nations must provide appropriate e-government services to assure confidence and effective and efficient usage among their citizens. The quality, security, and privacy of current e-government implementation have been impairing the trust and participation of users, in Jordan especially. Hence, this study examined the impacts of quality, security and privacy of e-government services on the intention to use e-government services among Jordanian citizens. Questionnaires were used to gather data, and questionnaire items covered the constructs of quality factors (information quality, system quality, and service quality), perceived security, and perceived privacy as independent variables, and the constructs of trust and intention to use as dependent variables. The study samples comprised academics in Jordanian public universities. The universities were selected using stratified sampling method, while the respondents were chosen using simple random sampling method - 212 respondents were selected. SPSS Version 18 and PLS Version 3.3.6 were used in data analyses and hypotheses testing. Results affirmed a positive and significant link between information quality, system quality, service quality, perceived security, perceived privacy and trust in e-government services, and a positive and significant link between trust in e-government services on intention to use. In e-government services implementation, Jordanian government should take into account the quality factors (information quality, system quality, and service quality), perceived privacy, and perceived security, to increase trust of the citizens and consequently their intention to use the e-government services.

A fuzzy based model for rainfall prediction
Authors: Zahran Bilal
Published: December 2022

Of all the current challenges faced by Jordan, the most severe is the inadequacy of the water supply. The country is almost entirely reliant on rainfall, whose pattern, however, is highly variable in terms of its frequency, regularity, and quantity. Evidently, therefore, the ability to anticipate rainfall accurately is critically important for the effective planning and management of water resources in Jordan, and particularly in agricultural areas. Influenced by a range of factors such as temperature, relative humidity, and wind speed, rainfall is a stochastic process. This paper suggests the use of a fuzzy model that draws upon data gathered at 26 stations situated in a range of locations throughout Jordan. The model is capable of forecasting seasonal rainfall relating to a specific station. Its ability to deliver predictions with an acceptable degree of accuracy has been demonstrated, and it can be concluded from this that the fuzzy technique can provide a model that is capable of efficiently forecasting seasonal rainfall.

The purpose of this study is to determine the impact of cloud-based solutions on the digital transformation of human resource (HR) practices in Jordan. The study is quantitative in nature and the data was gathered from primary sources by gathering the responses from 346 respondents. The SEM technique was used for the purpose of determining the direct effect. The study found that infrastructure as a service, performance as a service and software as a service had significant and positive impact on the digital transformation of the HR practices. The information gathered from the secondary sources was provided with reference and was also well paraphrased to avoid the issue of similarity. The study focused on the public sector which restricts the results of this study to this sector only. On the other hand, only one country was considered in this study i.e., Jordan. The research is considered as the first attempt to examine the impact of cloud-based solutions on the digital transformation of HR practices in a developing country such as Jordan.

A comparative study of umbrella branding approach versus house of brands approach and their influence on market share
Authors: Al-Raggad Mo’taz Mohammad Rath’an , Hashem Tareq N. , Al-Raqqad Rasha Mohammad Rath’an
Published: December 2022

The current study aims at examining the differences between umbrella branding and house of brands on organizational market share. Various variables are adopted including reach, efficiency, image and ambiguity. A sample of 98 marketing managers or their representatives within the chemical industry sector in Jordan, SPSS is employed to screen and analyze gathered data. Results of study indicate that umbrella branding has a bigger and much deeper influence on market share compared to house of brands which is attributed to many factors including that umbrella branding has a wider reach, it is more efficient and more able to shed the light and increase the focus on organization's image, meaning that in umbrella marketing the focus is more on the marketing organization more than manufacturing organization which increases its reputation and market share. The study recommends the necessity for each brand to have a specific purpose to avoid overlapping or disintegration of brands.
Examining the effect of social media interaction, E-WOM, and public relations: Assessing the mediating role of brand awareness

Artificial intelligence is user-friendly and possesses useful characteristics to share across the various services that are provided. By enhancing innovative contact, artificial intelligence applications (AIA) enable a more involved environment in governmental institutions. The goal of this study is to discover how users in the UAE feel about using AIA for educational reasons. Data collected from a survey of 387 university students were used to validate the model and hypotheses. The adoption features, such as perceived compatibility, trialability, relative advantage, ease of doing business, and technology export, are included in the conceptual model. The current study's practical implications are crucial in that they push the relevant educational authorities to comprehend the significance of each component and enable them to make plans and efforts in accordance with the order of the factors' relative importance. The managerial implications give educational sectors insight on how to apply AIA in their system to improve the growth of the provided service and to make the process easier for all users. The conceptual model of the paper, which links both traits of the individual and those of the technology, is what makes it new. The findings indicate that the diffusion theory variables outperform the other two variables of ease of doing business and technology export.

Introduction: The penetration into adjacent organs is a classical complication of peptic ulcer despite being less frequent than the other complications. The current work presents a rare case of gastric ulcer penetrating the duodenojejunal flexure and discusses the diagnostic difficulties, pitfalls, and current treatment strategy. Case report: A 63-years-old woman was admitted complaining of intermittent black stools defecations, and a weight of 44 kg. The referral gastroscopy revealed a 10 cm ulcer on the posterior wall of the stomach. The histology demonstrated severe gastritis with atypical cells. The hemoglobin level was 88g/l. The patient was scheduled for elective resection for suspected gastric cancer. The intraoperative finding was completely different – there was an ulcer approximately 4-5 cm in diameter infiltrating the transverse mesocolon and duodenojejunal flexure. The case was considered T4 cancer and we decided against elective gastrectomy. The postoperative CT showed an ulcer penetrating the duodenojejunal flexure. The second gastroscopy found an ulcer with a size of 3-4 cm. The multiple biopsies showed exacerbated chronic peptic ulcer with H. pylori infection, which was treated with proton pump inhibitors and antibiotics. The follow-up gastroscopy four months later demonstrated shrinkage of the ulcer to 15 mm with complete epithelization. One year later she gained 23 kg and was free of complaints. Conclusion: Penetration and fistulization to the duodenojejunal flexure are uncommon but possible complications of peptic ulcer disease. They are not an absolute indication for surgery. Decision-making should take into account the clinical presentation, patient age, and comorbidity.

Accidental infection by Trypanosoma cruzi (T. cruzi) usually occurs through accident with a sharp instrument during handling of infected animals in research laboratories. This case report describes the evolution of a case of accidentally acquired acute Chagas disease (CD). A 46-year-old female with suspicious symptoms of acute CD received medical care after reported a sharp puncture accident, during a laboratory procedure with an animal contaminated with T. cruzi. The direct search for T. cruzi in blood smear was positive. Benznidazole (BZN) 400 mg daily was started. The patient evolved with prompt remission of symptoms and completed 70 consecutive days of BZN with no adverse reactions, achieving parasitological, serological, and clinical cure within 6 months.
