Ballet Revenue Structures
Authors:   , Wellman Daniel J. , Yau Pamela
Published: July 2022

The financial health, and subsequent viability and stability of nonprofits has been a topic of discussion for several decades (Baumol and Bowen 1965). Leaders of nonprofits need access to relevant analyzation methods to effectively understand their financial data and to successfully assess their organization's financial health. Through my research, I focused specifically on the impact that revenue structures, and revenue diversification have on the financial health and sustainability of professional, US based ballet companies, and how these financial health analyses have affected the "bottom line" or net income for each organization. The sample includes ten professional, US based ballet/dance companies with operating budgets ranging from $13 million to $46 million. Data from the sample organization's Form 990's for fiscal years 2017-2019 was collected, and analyzed, and presented with a theoretical approach that is based on industry analytical standards that include the Diversification Index (Chang and Tuckman 1994, 276), which is derived from the Hirschman-Herfindahl Index for measuring revenue diversification, and Tuckman and Chang's methodologies for measuring financial vulnerability.

Contributing to management and marketing literature, this study empirically investigates the effectiveness of executive symbolism in influencing organizational recruitment from an intention to apply perspective. Drawing from Upper Echelons Theory, Signaling Theory and Screening Theory, we develop a set of hypotheses that predict a jobseeker's intent to apply after witnessing an act of executive symbolism. The predictive factors include the type of executive symbolism (i.e., primarily symbolic or partly symbolic (substantive)) and the credibility of the organizational leader. Additionally, we analyzed race and political ideology of the jobseeker to uncover if these variables had a moderating or mediating effect on intent to apply. Lastly, we discuss theoretical implications, practical implications, limitations, and an agenda for future research.

La intimidad conectada
Authors: Zafra Remedios
Published: July 2022

La cultura red ha dado lugar a nuevas formulaciones respecto a la intimidad y su transformación de los ámbitos de poder y relación. Los repliegues de la vida pública y privada que la configuran presentan lecturas ambivalentes si se hace referencia a la vida conectada y a la construcción ciudadana y subjetiva.  

Frente a la crítica hacia Internet como motor de exposición y mercantilización del sujeto, el feminismo ha logrado hacerse con la red para visibilizar y compartir lo privado desde una intencionalidad política. Este artículo pretende abordar algunas de las potencias y riesgos del feminismo en Internet como esfera público-privada donde se negocian nuevas formas de crear intimidad y ciudadanía.

Abrupt Disruption of Nicotine Addiction and Apathy after a Strategic Acute Brain Ischemia
Authors: Bagnati Pablo M.
Published: July 2022

Cigarette addiction shares common physiopathological mechanisms with other abuse drugs, mainly related to the brain reward circuits (1). Apathy is a neuropsychiatric disorder mostly related to cingulated gyrus damage, superior medial frontal and to disruption of neural networks connecting frontal structures with caudate nucleus, globus pallidus and thalamic nuclei (2). We describe a 62 year old patient with a history of severe smoking and hypertension who developed an abrupt disruption of nicotine addiction and apathy after ischemic stroke located in the left caudate head and the left pallidum area. The anatomic involvement of the rewards circuit areas are closely related to the abrupt cessation of smoking due to isquemic lesions descripted (3)(4). We hypothesize that apathy and smoking cessation could be related to “functional” bilateral fronto-subcortical circuit damage due to a combination of left pallidal and caudate stroke with a deaferentation of the right basal ganglia (3).
Inversión empresarial durante la pandemia en Colombia 2020-2021
Authors: Gómez-Mejía Alberto
Published: July 2022

Aplicando modelos Tobit, se evidencia que durante el período de la pandemia, marzo 2020-septiembre 2021, el comportamiento de la inversión y desarrollo (no digital) en 59 sectores empresariales colombianos, estuvo principalmente determinado por siete variables:  positivamente por la inversión en soluciones digitales, aumento del personal trabajando en casa, la disminución del flujo de efectivo empresarial, por el contrario, la inversión fue afectada negativamente por la reducción en los medios de pago (liquidez) y el difícil acceso a los servicios financieros (escasez de crédito), los gastos en bienes y procesos nuevos y mejorados y  la esperanza dada por las políticas de apoyo gubernamental. Es importante notar que las expectativas sobre el comportamiento de la economía colombiana en el año siguiente no fueron significativas. El grado del impacto del covid19 fue diferencial entre los sectores intensivos en tecnología y mano de obra no calificada.
Actitudes lingüísticas de los maestros bogotanos hacia el lenguaje inclusivo
Authors: Mahecha-Ovalle Andrés
Published: July 2022

Son diversas las proclamas que abogan por el uso constante del lenguaje inclusivo en las aulas de clase con el objeto de disminuir las brechas de discriminación e intolerancia ante la diversidad en el ámbito educativo. El presente estudio analiza las actitudes lingüísticas de los maestros bogotanos de la escuela pública respecto del uso lenguaje del inclusivo. La investigación se inscribe en el enfoque cualitativo con un alcance descriptivo. Se empleó el cuestionario sociolingüístico y la escala de Likert en la medición de las actitudes lingüísticas, instrumentos propios del método directo. En los hallazgos, se observa que las percepciones lingüísticas negativas se fundamentan en la corrección idiomática y en las directrices establecidas por la Real Academia Española. Asimismo, algunos maestros consideran necesario replantear la noción de lenguaje inclusivo, pues la actual no involucra el contexto escolar en su totalidad. Se concluye que los docentes asumen la normalización lingüística en la valoración del lenguaje inclusivo y, al mismo tiempo, consideran que las formas @, -e, -x no están insertas en su variedad lingüística.

THE SEMILINEAR COUPLED SYSTEMS FOR THE EXTERNAL DAMPING MODELS WITH VARIABLE COEFFICIENTS
Authors: Pham Trieu Duong
Published: July 2022

We present in this article some results on the global solvability with arbitrarily small data of the Cauchy problem for the following semilinear coupled system with a variable coefficient utt + a(x)(−∆)σu + ut = F(|D|αv, vt), vtt + a(x)(−∆)σv + vt = G(|D|αu, ut), u(0, x) = u0(x), ut(0, x) = u1(x), v(0, x) = v0(x), vt(0, x) = v1(x). The nonlinearities are of the form (F, G) = (||D|αv|p, ||D|αu|q), or (F, G) = (|vt|p, |ut|q), and the parameter σ satisfies σ ∈ (0, 1). We will show that the ”critical exponents” p, q for the small data global solvability have a close relation to the established exponents of the corresponding semilinear problems for the external damping equations.

Published: July 2022

In this study, we investigated the formation and influence of Ag particles on the physical properties and photocatalytic performance of Ag3PO4 photocatalysts when Ag particles adhered to the Ag3PO4 surface. The material is prepared by a simple precipitation method with illumination. The properties of the materials were investigated by X-ray diffraction (XRD), Raman scattering, scanning electron microscopy (SEM), UV-vis absorption, and the photocatalytic ability to decompose organic solutions. The results show the vibrational change of the [PO4] group in the structure presented in the Raman scattering spectrum highest RhB decomposition. The experimental results indicated that the Ag\Ag3PO4 showed highly efficient and stable photocatalytic activity under visible light irradiation. The Ag\Ag3PO4 sample with the Ag+\PO43- the ratio of 3.6\1 gave efficiency when stimulated with visible light of Xenon lamps. This sample degraded almost completely to RhB in 10 ppm solution after 15 min of illumination, with a decomposition rate of 0.241 min-1.

Authors: Quan Thi Minh Nguyet , Tran Thi Ngoc Hoa , Nguyen Van Duy , Nguyen Duc Hoa , Nguyen Van Hieu
Published: July 2022

In this study, heterojunctions of carbon nanotubes (CNTs) and tin oxide nanowires (SnO2) were investigated to determine their electrical performance for gas sensing applications. The I–V characteristics of the heterojunction were measured in air and H2S gas. The electrical parameters such as barrier height ϕB, ideality factor n, series resistance Rs, and reverse saturation current Io were extracted from the I-V plots. In H2S gas, the barrier height ϕB and series resistance Rs are lower compared to air, whereas the ideality factor n and saturation current Io are higher. These findings are essential for promoting technologies aimed at forming high-quality heterojunctions for gas sensing applications.

DEFUSE: Deep Fused End-to-End Video Text Detection and Recognition
Authors: Lokkondra Chaitra Yuvaraj , Ramegowda Dinesh , Thimmaiah Gopalakrishna Madigondanahalli , Vijaya Ajay Prakash Bassappa
Published: July 2022

Detecting and recognizing text in natural scene videos and images has brought more attention to computer vision researchers due to applications like robotic navigation and traffic sign detection. In addition, Optical Character Recognition (OCR) technology is applied to detect and recognize text on the license plate. It will be used in various commercial applications such as finding stolen cars, calculating parking fees, invoicing tolls, or controlling access to safety zones and aids in detecting fraud and secure data transactions in the banking industry. Much effort is required when scene text videos are in low contrast and motion blur with arbitrary orientations. Presently, text detection and recognition approaches are limited to static images like horizontal or approximately horizontal text. Detecting and recognizing text in videos with data dynamicity is more challenging because of the presence of multiple blurs caused by defocusing, motion, illumination changes, arbitrarily shaped, and occlusion. Thus, we proposed a combined DeepEAST (Deep Efficient and Accurate Scene Text Detector) and Keras OCR model to overcome these challenges in the proffered DEFUSE (Deep Fused) work. This two-combined technique detects the text regions and then deciphers the result into a machine-readable format. The proposed method has experimented with three different video datasets such as ICDAR 2015, Road Text 1K, and own video Datasets. Our results proved to be more effective with precision, recall, and F1-Score.
The formation of a heterogeneous-homogeneous catalytic system for the benzene alkylation with ethylene upon interaction of aluminum and carbon tetrachloride alloys
Authors: Arbuzov A. B. , Drozdov V. A. , Lavrenov A. V. , Leontieva N. N.
Published: July 2022

The in situ formation of the catalytic heterogeneous-homogeneous system including the Al-M (M = Ni, Co, Cu) alloy and the Al(M)/Cl complex in a benzene-ethylene medium at a temperature of 80 °C and pressure 0.2–0.3 MPa was studied. Regularities were found in the interaction of Al-M alloys activated by the liquid-metal Ga-In eutectic with a chlorinating agent (CCl4), which led to the formation of catalytically active Al(M)/Cl metal-aluminum chloride complexes. Spectrokinetic measurements showed that reactivity of the activated alloys toward an excess of CCl4 can form the following series: Al-Cu ≈ Al-Ni > Al > Al-Co. The highest catalytic activity was observed for the nickel-aluminum chloride complexes; their selectivity to ethyl benzene was up to 48 %. According to IR and UV-vis spectroscopy data, the structure and composition of the metal-chloride complexes formed in situ in the aromatic reaction medium are determined by a combination of the coupled ion pairs [AlCl4]–tetrahed./[NiCl6]4–octahed. and [AlCl4]–tetrahed./[CuCl2]–lin. stabilized by the (C6H5)3C+ carbocation.
Investigation of the hydroisomerization of diesel fractions with different concentration of nitrogen-containing compounds on bifunctional catalysts based on ZSM-23 and non-noble metals
Authors: Bogomolova T. S. , Smirnova M. Yu. , Klimov O. V. , Noskov A. S.
Published: July 2022

Bifunctional catalysts based on NiMo(W) sulfides and a ZSM-23-Al2O3 composite support have been synthesized. Their properties were studied in the transformations of diesel fractions with different nitrogen content (< 1, 10 and 20 ppm). It was demonstrated that the synthesized catalysts could be used to obtain hydrogenizates with the limiting filterability temperature  –38 °C, which comply with the requirements of GOST R 55475-2013 to the content of gasoline fraction and aromatic compounds, and the derived cetane number. Properties of the developed catalysts based on NiMo and NiW sulfides and characteristics of the corresponding hydrogenizates were compared with each other. In addition, properties of the developed samples were compared with the properties of a foreign commercial platinum catalyst for isodeparaffinization. The synthesized catalysts were found to be less selective than the reference sample, but more stable to N-containing compounds in the feedstock.
The Exchange Rate Volatility and Moroccan Exports: An Empirical Investigation
Authors: Louati Achraf , Echaoui Abdellah , Mouatassim Abdelatif
Published: July 2022

This article aims to study exchange rate volatility and its impact on exports. We examine using a VECM model the relationship between Moroccan exports and the volatility of the real effective exchange rate, over a period from the first quarter of 2000 to the first quarter of 2017. The methodology adopted takes into account the long-term relationship term between the variables, using the moving standard deviation as a measure of volatility and real-world GDP as a proxy for global demand. Although a large number of empirical studies find that exchange rate volatility tends to reduce the level of foreign trade. Our results indicate that the increase in exchange rate volatility has a positive effect on the demand for Moroccan exports. Also, the short-term dynamics show that the Granger causal effects of volatility on real exports are significant. Moreover, this article joins the empirical studies that confirm the risk-loving behaviour of exporters in the face of risk of fluctuating exchange rates.
Terrorism and investment in Africa: Exploring the role of military expenditure
Authors: Iheonu Chimere O. , Ichoku Hyacinth E.
Published: July 2022

The aim of this study is to investigate the influence of military expenditure on the relationship between terrorism and investment in twenty-four African countries for the period 2001 to 2018. The study utilizes fixed effects regression with Driscoll and Kraay standard error and cushions the effect of simultaneity and reverse causality using the lags of the regressors as instruments. The empirical results reveal the negative effect of terrorism on both domestic investment and foreign direct investment (FDI). The study further reveals a negative net effect of military expenditure on the relationship between terrorism and investment. Furthermore, it was discovered that a threshold of 2% to 5% of military expenditure in GDP is required for military expenditure to offset the negative effect of terrorism on FDI. The study recommends that counter-terrorism initiatives be tailored more towards inclusive growth policies, increasing access to education, and improving the quality of governance.

The Role of the Public-Private Partnership (PPP) in Achieving the Optimal Economic and Social Benefits Through the Port Sector
Authors: Hamed Al Habsi Faisal Amur Said , Ullah Asad
Published: July 2022

PPP model is very essential for the success of any partnership between the public and private sector. In this review the types of the PPP models will be analysed, evaluated and proper models will be highlighted. The literature will provide sufficient information about the PPP in one of the developing countries and will also highlight on the work that has been done previously and make proper evaluation of the current situation. This paper presents a theoretical and critical review of the past studies in the PPP program, along with a revision of the outcome and conclusion. The findings of the study suggest that implementation and use of PPP has a significant economic impact on the port sector as it leads to the creation of jobs, can mobilize more financing techniques for infrastructure and multi payment options. The PPP focus more into the efficiency gains, rather than focusing on the expansion of the infrastructure which achieve the best value for money for the government and prevent overspending.

Barely Tweeting and Rarely About Racism: Assessing US State Health Department Twitter Use During the COVID -19 Vaccine Rollout
Authors: Bradford Natalie J. , Amani Bita , Walker Valencia P. , Sharif Mienah Z. , Ford Chandra L.
Published: July 2022

Introduction: The general public was discussing racism and potential inequities in COVID-19 vaccinations among Afri­can Americans on Twitter before the first COVID-19 vaccine received emergency use authorization, but it is unclear how US state health departments (SHDs) were using Twitter to address the inequities. This study examines the frequency, content and timing of SHD tweets during the US rollout of the first SARS Co-V2 vaccine.Methods: This was a prospective study of tweets posted from the official Twitter ac­counts of each of the 50 US SHDs and the DC health department from October 19, 2020 to February 28, 2021. We retrieved the content and metadata of 100% of their tweets; calculated frequencies and propor­tions of tweets containing key terms related to COVID-19 vaccines, equity and racism; stratified the data by region; and charted longitudinal trends.Results: Overall, SHDs tweeted infrequent­ly, and rarely tweeted about inequities, mis­trust or racism. Though 55.48% of all SHD tweets were about COVID-19, hardly any tweets contained the terms: race/ethnic­ity (1.20%); equity (1.09); mistrust (.59%); or racism (.06%). Similar patterns existed among vaccination-related tweets, which accounted for 24.38% of all tweets. Only 21.64% of vaccination-related tweets con­taining any race/ethnicity, equity, mistrust, or racism terms were posted prior to the first Emergency Use Authorization (EUA). Those about African Americans (70.45%) were posted ≥8 weeks after EUA.Conclusions: Concerns about racism and inequities in COVID-19 vaccination continue on Twitter, but SHDs rarely tweet about them. This strikes a worrisome chord of disconnection from the science linking health inequities to racism.Ethn Dis.2022; 32(3):257-264; doi:10.18865/ed.32.3.257
Some thoughts on the morphotectonic development of the Denizli region Basic
Authors: YILMAZ Yücel
Published: July 2022

The Denizli region is located to the east of the Buldan horst. Although they follow the same trends as the Büyük Menderes and Gediz grabens, the Denizli region has undergone semi-independent evolution during the Quaternary. The essential morphotectonic elements of the area are the Denizli basin and the surrounding Babadağ and the Güzelpınar horsts. The Babadağ horst is the most distinct morphotectonic element of the region. It is bounded in the North by the Denizli fault, a listric normal fault, possibly a major detachment fault. The Laodicea and Güzelpınar horsts located within the downthrown block of the fault may be regarded as antithetic structures.
MEASURING TRANSPORT-RELATED SOCIAL EXCLUSION AT THE MESO-LEVEL USING THE CONCEPT OF ISOLATED ISLANDS IN THE BIG CITIES
Authors: HAI Dinh Tuan , QUANG Nguyen Ngoc
Published: July 2022

Using the notion of isolated urban islands, this paper discusses, from a theoretical point of view, three important but controversial issues related to the measurement of social exclusion in the big cities: (i) the extent to which social exclusion is likely to occur, (ii) accessibility indicators that are sensitive and relevant for the evaluation of social exclusion, and (iii) the geographical scale for evaluation. From an urban island point of view, two important issues have been raised: the distribution of jobs, Therefore, basic facilities, and services within an urban island and the travels of people between urban islands. social exclusion can be determined either by the affordability/acceptability of travel time/cost to access the minimum requirement of facilities/services or the number of facilities/services in reach of the individuals within acceptable/affordable travel time and cost. A person will be at risk of social exclusion if they belong to a minority group as opposed to the majority in the same society. Some levels of social exclusion risk have been proposed. The evaluation should be implemented at the meso-level (urban island). From the view of the urban islands, the issues of transportrelated social exclusion are clearly understood, and measurements of social exclusion should be solved. We feel that a detailed survey/interview is needed for areas at high risk of social exclusion, followed by an evaluation at the micro-level to identify excluded people and the causes for their exclusion. It is expected that this paper will attract researchers to pay more attention to this issue.
MATHEMATICAL MODELING OF THE AEROION MODE IN A CAR
Authors: BILIAIEV Mykola , PSHINKO Oleksandr , RUSAKOVA Tetiana , BILIAIEVA Viktoriia , SŁADKOWSKI Aleksander
Published: July 2022

In this study, a mathematical method is proposed for calculating the concentration field of air ions of different polarities and dust levels in the passenger compartment, taking into account the geometry of the passenger compartment and seats, shelves, and other internal elements of the passenger compartment. The method also takes into account changes in the rate of the air flow ventilation, the location and number of ionizers, and sources of positive ions and dust, taking into account their different intensities and locations. On the basis of a numerical model for this method, software has been developed that allows users to carry out computational experiments without requiring much time for calculation. Based on the results, the optimal location of the ionizer in the passenger compartment of the car was determined to ensure comfortable conditions for the stay of passengers, which favorably affects their health. It has been found that the presence of two ionizers is optimal for creating comfort in the car with an ionization intensity of Q = n . 0 × 21 10 11 Q = n . 0 × 47 10 10 ions/s located at the top of the car. If there is one ionizer located on the dashboard or at the top of the car with a higher ionization rate than ions/s, it is not possible to simultaneously provide optimal ionization parameters for passengers in the front and rear seats of the car.
HOW DOES FINE PARTICULATE MATTER IMPACT PUBLIC TRANSIT RIDERSHIP?
Authors: JUNG Hojin
Published: July 2022

We explore how a rapid rise in air pollutants impacts the ridership of public transportation. Based on the individual purchase history, our comprehensive analyses document evidence that an elevated level of concentrations of fine particulate matter caused a substantial change in individual decisions on public transit ridership in relation to individual social and economic characteristics. The estimated effect primarily arose from the fear of exposure to pollutants and, consequently, is substantially different from other macroeconomic influences. Our empirical results contribute important inferences about commuters’ choices of transit modes during the period of ambient air pollution and offer significant guidance for policymakers and practitioners.
EFFECTIVENESS OF PREVENTIVE SECURITY MEASURES AND CRIMINAL ACTS AGAINST CIVIL AVIATION
Authors: KORECKI Zbyšek , HOIKA Tomáš
Published: July 2022

The development of measures in civil aviation protection against illegal acts is based on the analysis of incidents, which can be divided into four development stages. Before 9/11, civil aviation entities were mostly reactive; only new threats warranted a proactive approach to mitigating air threats. The present article’s aim was to analyse the development of methods for checking passengers and objects intended for air transport. The analysis of selected incidents, control processes, and the level of security achieved confirm that the implemented security methods and proactive approach to working with air traffic risks are a suitable compromise between passenger comfort, technological development of detection devices, and processes at the airport.
DETERMINATION OF THE IMPACT OF DISRUPTIONS IN GROUND HANDLING ON AIRCRAFT FUEL CONSUMPTION
Authors: GŁADYŚ Sylwester , KWASIBORSKA Anna , POSTÓŁ Jakub
Published: July 2022

The authors of the paper distinguished two basic problems that occur during the ground handling of aircraft. The first one concerns the identification of disruptions during ground handling that have an impact on the scheduled completion of ground handling. The second problem is determining how these disturbances affect the environment by estimating the increased fuel consumption of the aircraft. In the first step, a catalog of disruptions in the ground handling process of the aircraft, which delays the performance of subsequent aircraft operations, was developed. Simio software was used to analyze the impact of disturbances on the performance of ground service, in which random disturbances were simulated. The simulation was run for several variants, taking into account the sample aircraft and various airlines. The developed model allows for the analysis of the impact of disturbances on the punctual performance of the ground service of the aircraft for various variants with given probability values. In the next step, simulations were performed to determine the impact of the disturbances on the increase in fuel consumption by the aircraft. Research has shown that even minor disruptions increase an aircraft’s fuel consumption over a 200-km flight path. The analyzes carried out in this work are of great importance for sales agents and airlines who strive to minimize the duration of elementary activities and eliminate threats during ground handling. Additionally, it is important from the point of view of environmental protection. As research has shown, even small disturbances can substantially increase fuel consumption, which is not beneficial for airlines. Past research has focused on the analysis of fuel consumption by aircraft and emissions during takeoff and landing operations and taxiing aircraft. There is a large correlation between the disturbances occurring at the parking place and increased fuel consumption, which is important from an economic and environmental point of view.

A Large-Scale Dataset of Twitter Chatter about Online Learning during the Current COVID-19 Omicron Wave
Authors: Thakur Nirmalya
Published: July 2022

The COVID-19 Omicron variant, reported to be the most immune evasive variant of COVID-19, is resulting in a surge of COVID-19 cases globally. This has caused schools, colleges, and universities in different parts of the world to transition to online learning. As a result, social media platforms such as Twitter are seeing an increase in conversations related to online learning. Mining such conversations, such as Tweets, to develop a dataset can serve as a data resource for interdisciplinary research related to the analysis of interest, views, opinions, perspectives, attitudes, and feedback towards online learning during the current surge of COVID-19 cases caused by the Omicron variant. Therefore this work presents a large-scale public Twitter dataset of conversations about online learning since the first detected case of the COVID-19 Omicron variant in November 2021. The dataset is compliant with the privacy policy, developer agreement, and guidelines for content redistribution of Twitter, as well as with the FAIR principles (Findability, Accessibility, Interoperability, and Reusability) principles for scientific data management. The paper also briefly outlines some potential applications in the fields of Big Data, Data Mining, Natural Language Processing, and their related disciplines, with a specific focus on online learning during this Omicron wave that may be studied, explored, and investigated by using this dataset.
Twitter Big Data as A Resource for Exoskeleton Research: A Large-Scale Dataset of about 140,000 Tweets and 100 Research Questions
Authors: Thakur Nirmalya
Published: July 2022

The exoskeleton technology has been rapidly advancing in the recent past due to its multitude of applications and diverse use-cases in assisted living, military, healthcare, firefighting, and industry 4.0. The exoskeleton market is projected to increase by multiple times of its current value within the next two years. Therefore, it is crucial to study the degree and trends of user interest, views, opinions, perspectives, attitudes, acceptance, feedback, engagement, buying behavior, and satisfaction, towards exoskeletons, for which the availability of Big Data of conversations about exoskeletons is necessary. The Internet of Everything style of today's living, characterized by people spending more time on the internet than ever before, with a specific focus on social media platforms, holds the potential for the development of such a dataset, by the mining of relevant social media conversations. Twitter, one such social media platform, is highly popular amongst all age groups, where the topics found in the conversation paradigms include emerging technologies such as exoskeletons. To address this research challenge, this work makes two scientific contributions to this field. First, it presents an open-access dataset of about 140,000 tweets about exoskeletons that were posted in a 5-year period from May 21, 2017, to May 21, 2022. Second, based on a comprehensive review of the recent works in the fields of Big Data, Natural Language Processing, Information Retrieval, Data Mining, Pattern Recognition, and Artificial Intelligence that may be applied to relevant Twitter data for advancing research, innovation, and discovery in the field of exoskeleton research, a total of 100 Research Questions are presented for researchers to study, analyze, evaluate, ideate, and investigate based on this dataset.

Background: Primary central nervous system lymphomas (PCNSLs) are sensitive to chemotherapy. Standard treatment is high-dose methotrexate (MTX)-based chemotherapy. There are no reports of successful treatment of acute uric acid nephropathy with rasburicase after MTX administration in PCNSL. Case presentation: A 54-year-old man with a history of gout presented with character change and memory loss. MRI showed a large, enhancing mass spanning the bilateral frontal lobes and right temporal lobe. After endoscopic biopsy, MTX, procarbazine and vincristine (MPV) regimen was initiated for treatment of PCNSL. After initiation of chemotherapy, the patient suffered from a gout attack and blood examination revealed acute renal failure (ARF) and hyperuricemia. The considered causes of ARF included MTX toxicity and acute urid acid nephropathy. Since a good response to chemotherapy was observed, the latter was assumed. After improvement of renal function, MTX was resumed, initiating rasburicase for control of hyperuricemia. A complete response was obtained after induction chemotherapy. Hyperuricemia was controlled with rasburicase and renal function was preserved. Conclusions: Acute uric acid nephropathy should be considered when ARF occurs after initiation of MTX in PCNSL. For newly diagnosed PCNSL patients with large tumors or hyperuricemia, upfront usage of rasburicase should be considered to prevent it.
Polygenic Risk Score and Risk Factors for Gestational Diabetes

Published: July 2022

Gestational diabetes mellitus (GDM) is a common complication of pregnancy that adversely affects maternal and offspring health. A variety of risk factors, such as BMI and age, have been associated with increased risks of gestational diabetes. However, in many cases gestational diabetes occurs in healthy nulliparous women with no obvious risk factors. Emerging data suggest that the tendency to develop gestational diabetes has genetic and environmental components. Here we develop a polygenic risk score for gestational diabetes. We further investigate relationships between the genetic architecture of GDM and genetically constructed risk factors and biomarkers. Our results show that genetics can be used as an early screening tool that identifies at-risk at higher risk of GDM before its onset to propose comprehensive monitoring and preventative programs to mitigate the risks.

External stressors strongly increase cardiovascular activity and induce metabolic changes that ensure the availability of glucose and oxygen as part of a co-ordinated stress response. Exposure to stress during early life appears to have an exaggerated long-term effect on this response, leading to an increased risk or cardiometabolic disorders. Here we demonstrate that acute stress induced glucose release is impacted by the early life environment in rodent maternal deprivation and early-life infection models and this was validated in our EpiPath human early-life adversity cohort. In all three models differences in baseline blood glucose levels after ELA exposure were sex dependent. The human ELA model showed higher levels of basal glucose in females, similar to the mouse infection and rat maternal deprivation models. We anticipated that the stress induced glucose rise would be a GC dependent process. However, the kinetics of stress-induced glucose release, peaking 15-28 minutes before cortisol suggest that it is a GC-independent process. We confirmed this by administering an escalating dose of cortisol to a health human cohort, and the inability of an intravenous GC bolus induce a glucose rise in man confirms that it is a rapid, GC independent, process.In conclusion, we provide a novel perspective on the mechanisms behind stress related metabolic changes and highlights the importance of collecting early life data as a measure to understand an individual’s metabolic status in a better light.
Protocol of the Dual Burden of Animal and Human Zoonoses: A Systematic Review

Published: July 2022

Background: When we talk about zoonoses, it is undeniable that we have a human and animal population that has been isolated in studies over time. Besides human and animal health, zoonoses also impact the economy and society. Therefore, the integration of the analysis in this area is essential to optimize resources in public health decisions. We have new challenges in public health that we need to overcome in a more comprehensive method such as One Health. For better measures in public health, the dual burden of zoonoses seems a logical way to determine the integral impact of such diseases in society and thus take better measures to prevent and reduce the impact of these diseases. Methods: We follow the guidelines for “Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). We search human and animal zoonoses on Embase, Ovid Medline, Scopus, Web of Science, and Google Scholar, from an unrestricted period until November 2021. For the search, we consider the Disability Adjusted Life Years (DALYs) for the human zoonotic burden and the animal zoonotic burden in monetary terms. A librarian collaborates to optimize the search string for the databases, and two reviewers screen eligible articles (first by title, then by abstracts, and finally, by full-text assessment.) For the analysis, we aim to convert the burden of zoonoses of all selected studies into the zoonotic Disability Adjusted Life Years (zDALYs) – including the human and animal components. Discussion: The study results will provide information on published studies that have accounted for the dual burden of zoonoses (both human and animal health aspects.) In addition, the synthesis of the available literature will address the knowledge gap in this area in order to know to what extent it is possible to convert the burden of human zoonoses to the animal burden of zoonoses and integrate them into a more comprehensive approach (dual burden of zoonoses.)
