Will China Take Over the World in the Middle of the 21st Century?
Authors: Fiszer Józef
Published: September 2022

The subject of this article is China and the analysis of its chances of gaining the status of the number one superpower in the world by the middle of the 21st century. I try to answer two fundamental questions here: Will China take over the world in the middle of the 21st century and will the United States and its allies allow this to happen? I try to answer these in both theoretical and utilitarian terms. I refer to several research theories, including the theory of equilibrium support and George Modelski’s long cycle theory. Above all, I refer to the theory of the state’s foreign policy, the theory of classical realism and the theory of hegemonic change. I use a comparative method and a critical discourse analysis, among others.The main hypothesis of the article is the conclusion that the United States is slowly losing its position as a global hegemon in the international arena, which strengthens China’s chances of achieving its strategic goal in international politics, which is to take over the world by the mid-21st century.However, this will not be an easy task. It will depend on many factors, including the internal situation in China and the policy of the United States and its allies towards Chinese aspirations, as well as Russia’s position on this issue, which is already competing with China’s growing influence in the world. China may also join forces with Russia and collectively deprive the United States of its hegemonic status. On the other hand, there is a tendency in political science to assume that Russia-China relations are a balancing alliance for the United States. However, this practice may verify the overall Russia-China relations in favour of the United States, thanks to which it will manage to maintain control over the world and defend its status as a hegemon in the international arena.

One of the most important technological challenges that photoconductive devices in terahertz systems encounter is the viability of cost-effective and large-scale device production. We introduce an economical and mass-producible approach to fabricating a substrate material for photoconductive devices. By using an electron beam irradiator, the material properties of GaAs were engineered in a controllable manner, achieving comparable performance to that of a well-known photoconductive substrate, LT-GaAs. THz emission of the irradiated substrates was tested and found to be superior to a commercial device in terms of high-power THz signal emission and ability to withstand a high bias voltage.
Terahertz Channel Propagation Phenomena, Measurement Techniques and Modeling for 6G Wireless Communication Applications: a Survey, Open Challenges and Future Research Directions
Authors: Serghiou Demos , Khalily Mohsen , Brown Tim , Tafazolli Rahim
Published: September 2022

The Terahertz (THz) band (0.3-3.0 THz), spans a great portion of the Radio Frequency (RF) spectrum that is mostly unoccupied and unregulated. It is a potential candidate for application in Sixth-Generation (6G) wireless networks, as it has the capabilities of satisfying the high data rate and capacity requirements of future wireless communication systems. Profound knowledge of the propagation channel is crucial in communication systems design, which nonetheless is still at its infancy, as channel modeling at THz frequencies has been mostly limited to characterizing fixed Point-to-Point (PtP) scenarios up to 300 GHz. Provided the technology matures enough and models adapt to the distinctive characteristics of the THz wave, future wireless communication systems will enable a plethora of new use cases and applications to be realized, in addition to delivering higher spectral efficiencies that would ultimately enhance the Quality-of-Service (QoS) to the end user. In this paper, we provide an insight into THz channel propagation characteristics, measurement capabilities, and modeling techniques for 6G communication applications, along with guidelines and recommendations that will aid future characterization efforts in the THz band. We survey the most recent and important measurement campaigns and modeling efforts found in literature, based on the use cases and system requirements identified. Finally, we discuss the challenges and limitations of measurement and modeling at such high frequencies and contemplate the future research outlook toward realizing the 6G vision.
Who rides Uber anyway? A census-tract level analysis and clustering of ride-shares for the city of Chicago during the era of the pandemic
Authors: Rafi Shakil , Nithila Arna Nishita
Published: September 2022

The COVID-19 pandemic has led to an unprecedented change in transportation, including shared mobility services. This study attempted to identify the user group of ride-share services by leveraging daily ride-sharing trip data for the year of 2020 associated with other socio-demographic and built-environment attributes of Chicago, Illinois. The study employed K-means clustering for user group segmentation. Results show: i) the cluster with the largest share of census tracts generate lowest average trips which is clearly an impact of the pandemic; ii) The high-income cluster generates short trip and coupled with high population, land-use, and employment density; iii) The low-income cluster generates longer trips coupled with diversity of land-use mx, employment and population density. Results of this study provide insights for policymakers and ride- sharing operators to ensure access to the services among the population irrespective of spatial diversity.
Multiple CUAV-Enabled mMTC and URLLC Services: Review of Energy Efficiency and Latency Performance
Authors: Sabuj Saifur
Published: September 2022

Cognitive unmanned aerial vehicles (CUAVs) play a vital role in next-generation wireless networks as they assist in massive machine-type communication (mMTC) and ultra-reliable low-latency communication (URLLC) services. This study focuses on multiple CUAV-enabled networks, wherein CUAVs are paired with each other. We analyze the data rate, energy efficiency, and latency of such networks by applying the finite information block length theory, wherein mMTC and URLLC information use a non-orthogonal multiple access technique. Furthermore, we formulate an optimization problem to maximize the energy efficiency of paired CUAV devices by jointly optimizing the transmission power of the mMTC and URLLC information to satisfy the latency requirement. The numerical results indicate that our proposed multiple-CUAV-enabled scheme enhances the network performance of CUAV devices in terms of energy efficiency and latency better than the existing scheme.
Latent Similarity Identifies Important Functional Connections for Phenotype Prediction
Authors: Orlichenko Anton
Published: September 2022

We present a new machine learning algorithm, Latent Similarity, and use it to predict subject (endo)phenotypes from fMRI data. fMRI can be used to predict dysfunctional mental states. In addition, endophenotypes are known to be predictive of disease status, and are of interest in developmental studies. However, fMRI studies often suffer from small cohort size and high feature dimensionality, making reproducible prediction challenging. The innovation of our algorithm is to combine a kernel similarity function with metric learning to increase the robustness of prediction. Our algorithm becomes robust by utilizing the N squared connections between the N subjects in the cohort, rather than the features of the N subjects themselves. We identify important functional connections in the default mode and uncategorized functional networks for predicting age, sex, and intelligence. We also find that only a few connections contain most of the information required for any predictive task. We believe that our algorithm can be beneficial in small sample size, high noise, high dimensionality settings.

Published: September 2022

В работе рассматривается влияние кормового дейдвуда на гидродинамические характеристики расположенного за ним судового руля. Задача решается расчетным путем с использованием нелинейного метода тонкой несущей поверхности. В расчетах варьируется расстояние между дейдвудом и носовой кромкой руля. В рассматриваемом установившемся криволинейном движении угол дрейфа изменяется от 0 до 20 градусов, безразмерная угловая скорость – от 0 до 0,756. Расчеты выполнены для двух крыльев, имитирующих корпус судна, удлинением 0,045 и 0,06. Исследование показало наличие влияния дейдвуда на гидродинамические характеристики руля в пределах расстояния до одной хорды руля. Уровень влияния существенно зависит от угла дрейфа и угловой скорости движения судна. В целом, результаты исследования способствуют уточнению математической модели судовых рулей, навешенных на кормовой дейдвуд. Кроме указанного в работе получен также ряд сведений, представляющих интерес при изучении управляемости судов.

The article considers the influence of the aft deadwood on the hydrodynamic characteristics of the ship's rudder located behind it. The problem is solved by calculation using the nonlinear thin bearing surface method. The distance between the deadwood and the forward edge of the rudder varies in the calculations. In the steady curvilinear motion under consideration, the drift angle varies from 0 to 20 degrees, the dimensionless angular velocity varies from 0 to 0.756. Calculations were made for two wings imitating the ship's hull with an aspect ratio of 0.045 and 0.06. The study showed the influence of deadwood on the hydrodynamic characteristics of the rudder within the distance to one rudder chord. The level of influence significantly depends on the drift angle and the angular velocity of the ship. In general, the results of the study contribute to the refinement of the mathematical model of the ship's rudders hung on the stern deadwood. In addition to the information indicated in the work, a number of information was also obtained that is of interest in studying the controllability of ships.

Published: September 2022

Настоящая статья является шестой заключительной из цикла статей, посвященных корректировке кодекса ИМО по остойчивости в части ограничений продольной качки. В ней рассмотрена оценка мореходности транспортных судов в соответствии с ограничениями по погоде из условий, возникающих при продольной качке и предложены критерии оценки этих явлений на нерегулярном волнении разной интенсивности. На основании выполненных систематических расчетов продольной качки на нерегулярном волнении получены зависимости ограничений скорости хода транспортных судов в зависимости от предельных показателей мореходности: вертикальных ускорений, слеминга, заливаемости, амплитуд килевой качки. Полученные зависимости позволяют оценить мореходность. При этом ставится цель расширения нормативной базы для обоснованного назначения эксплуатационных ограничений по погоде и району плавания судов при совершенствовании Правил Российского Морского Регист­ра Судоходства на основе общего подхода к нормированию мореходности, со­гласующегося с методикой разработки новой Международной конвенции о гру­зовой марке 2000. Предлагаемый подход к определению критериев мореходности для оценки эксплуатационных ограничений судов по погоде из условий мореходности может быть использован на практике для совершенст­вования нормативных требований Регистра.

During the dynamic impact of the wind load the ratio of extremely withstand heeling moment of the ship, sometimes referred to as the minimum overturning moment, to the calculated heeling moment from wind pressure is usually considered. This ratio is called the safety factor or the stability criterion of the weather, as well as the basic criterion. The Assessment of dynamic stability of the ship is significantly complicated if the criterion of the weather takes into account not only the heeling from wind load, but from the incoming waves also. The total effect of the heeling moments on the ship depends on several factors: the nature of incoming waves, location of the ship relative to the excitement, the degree of dynamic wind load, the phase shift between heeling moment from wind pressure and excited moment of the waves. When building a criterion of weather the above-mentioned factors can be taken into account in different ways, in different degrees and in different combinations, but always trying to satisfy the obvious conditions: the selected combination of impact of wind and waves should be, on the one hand sufficiently hard for stability and on the other, — it is probable in the sense that it occurs during operation.

A method is proposed for constructing an adaptive model of the horizontal movement of a vessel for various modes and conditions of navigation, as a control system for its parameters. The process of setting up the initial nonlinear model is carried out on the basis of identification tasks of the simulated process in comparison with the real process of ship movement. The assessment of the conformity of the adaptation of the nonlinear model to the real movement of the vessel is carried out using the quadratic criterion of generalized work. The task of the identification system is formed by the methods of analytical design of optimal regulators by A.A. Krasovsky to control the rates of change of the adjustable parameters of the adaptive model according to the criterion of generalized work. The control effects of changing the adjustable parameters of the adaptive model are obtained. The performance of the adaptive model is confirmed by the experimental data of the motion of the simulation model of the vessel. The above experimental modeling showed a good quality of identification and adaptation of the generalized model of vessel movement in the proposed way. Recommendations are given on the choice of the main parameters of the identification system: the time constant and the gain coefficients of the configurable parameters. The adaptive model is intended as a predictive one in automatic control systems and decision support by the skipper.

El presente trabajo tiene la finalidad de estudiar una parte de la organización social del casino, la que hemos llamado organización interaccional, en ella lo importante son los encuentros de juego. Esa organización tiene un trasmundo, una cara oculta, que implica una tensión histórica entre casinos y estafadores. Se pretende estudiar ese conflicto desde el punto de vista interaccional a partir del método etnográfico y datos históricos de casos de estafadores. Los resultados permiten observar, de manera tópica y general, que la organización interaccional habitual del casino es más que puro y mero azar o probabilidades, sino un poco más allá de ello, son maquinaciones de juegos de azar, pues si no fuera así los estafadores no intentaran desmantelar dicha maquinación. El mecanismo de la estafa, al menos desde el marco interactivo, se puede visualizar con un concepto llamado interacción connivente, o vinculación conflictiva entre estafadores y personal del casino.
Macro-Level Determinants of Entrepreneurship and Endogeneity Bias – A Methodological Contribution
Authors: Gaies Brahim , Maalaoui Adnane
Published: September 2022

The eclectic theory of entrepreneurship has identified several macro-determinants of national entrepreneurial activities. Taking advantage of the availability of new databases, several recent empirical studies have sought to test these determinants in multicountry studies using multivariate regression models. Due to the lack of consensus around their results, this paper posits that this empirical literature may be subject to endogeneity bias, which seriously threatens its accuracy, consistency, and reliability, as well as the effectiveness of the resulting management and policy recommendations. Consequently, we methodologically demonstrate why and how endogeneity occurs in these studies by analyzing their empirical and theoretical models. We also provide a step-by-step guide to help researchers understand how to detect and correct endogeneity using IV techniques applied to a panel data analysis of the macro-determinants of early-stage entrepreneurship in a sample of 48 countries between 2000 and 2019. A ‘toolkit’ of generic STATA software commands specifying the tests, methods, and assumptions performed in this analysis is included. In doing so, we aim to raise awareness of endogeneity bias among researchers and to empirically guide future studies in order to avoid its hazards. Finally, after correcting for endogeneity, our analysis identifies the protection of property rights, entrepreneurial culture, income, and economic development as the most consistent macro-determinants of early-stage entrepreneurship, providing important policy and business insights.
Human Activity and Gesture Recognition Based on WiFi Using Deep Convolutional Neural Networks
Authors: Jawad Sokienah , Alaziz Musaab
Published: September 2022

WiFi-based human activity and gesture recognition explore the interaction between the human hand or body movements and the reflected WiFi signals to identify various activities. This type of recognition has received much attention in recent years since it does not require wearing special sensors or installing cameras. This paper aims to investigate human activity and gesture recognition schemes that use Channel State Information (CSI) provided by WiFi devices. To achieve high accuracy in the measurement, deep learning models such as AlexNet, VGG 19, and SqueezeNet were used for classification and extracting features automatically. Firstly, outliers are removed from the amplitude of each CSI stream during the preprocessing stage by using the Hampel identifier algorithm. Next, the RGB images are created for each activity to feed as input to Deep Convolutional Neural Networks. After that, data augmentation is implemented to reduce the overfitting problems in deep learning models. Finally, the proposed method is evaluated on a publicly available dataset called WiAR, which contains 10 volunteers, each of whom executes 16 activities. The experiment results demonstrate that AlexNet, VGG19, and SqueezeNet all have high recognition accuracy of 99.17 %, 96.25%, and 100 %, respectively.

Aim: The aim of this study is to present the development of the concept of law enforcement science from one period to the next, using the works of thinkers considered by the authors to be decisive, in a unique way. To demonstrate, by exploring the origins of law enforcement science, that one can only fully understand a science if one also knows its history.Methodology: The authors of the present study, by presenting certain periods in the development of law enforcement science, juxtapose the defining ideas of nearly one hundred works, perhaps little known to many, which are of extraordinary scientific value even today.Findings: No matter how the concept of policing may change or evolve, it still carries with it a certain essential constancy, for there are permanent tasks of policing which have been the object of „policing” activity at every stage of its development and which are still the tasks of policing, and without which policing is unimaginable.Value: Young law enforcement academics should strive to explore the issues at stake from as many levels and perspectives as possible, with the necessary scientific rigour. The methodological approach should be based on an inquisitive attitude that seeks to understand the social phenomena that frame the reality of policing, at both institutional and individual levels. Their study will help to achieve this.

Elements with weak and blended spectral features in stellar spectra are challenging to measure and require specialized analysis methods to precisely measure their chemical abundances. In this work, we have created a catalog of approximately 120,000 giants with high signal-to-noise Apache Point Observatory Galactic Evolution Experiment (APOGEE) Data Release 17 (DR17) spectra, for which we explore weak and blended species to measure Na, P, S, V, Cu, Ce, and Nd abundances and 12C/13C isotopic ratios. We employ an updated version of the Brussels Automatic Code for Characterizing High-accuracy Spectra (BACCHUS) code to derive these abundances using the stellar parameters measured by APOGEE’s DR17 Stellar Parameters and Chemical Abundances Pipeline, quality flagging to identify suspect spectral lines, and a prescription for upper limits. Combined, these allow us to provide our BACCHUS Analysis of Weak Lines in APOGEE Spectra catalog of precise chemical abundances for these weak and blended species, which agrees well with the literature and improves upon APOGEE abundances for these elements, some of which are unable to be measured with APOGEE’s current, grid-based approach without computationally expensive expansions. This new catalog can be used alongside APOGEE and provides measurements for many scientific applications ranging from nuclear physics to Galactic chemical evolution and Milky Way population studies. To illustrate this we show some examples of uses for this catalog, such as showing that we observe stars with enhanced s-process abundances or that we can use the 12C/13C ratios to explore extra mixing along the red giant branch.

BACKGROUND: West Java is ranked 4th as the province with the highest number of COVID-19 cases in Indonesia up to December 1, 2020. The COVID-19 pandemic has a major impact on human health, lifestyle changes, and economic life.

AIM: The purpose of this study was to analyze the impact of the COVID-19 pandemic on lifestyle changes among the community of West Java.

METHODS: The study was conducted in September 2020 using a cross-sectional study design. A total of 2502 people aged ≥12 years living in West Java were involved in this study as a sample, willing to fill out a questionnaire in the form of a Google form that was distributed online through social media (WhatsApp, Facebook, and Instagram).

RESULTS: The results showed that the COVID-19 pandemic had an effect on lifestyle changes in the people of West Java. During the COVID-19 pandemic, the people of West Java became more frequent to wash their hands, do regular exercise, sunbathe in the morning, consume more vegetables and fruits, and consume vitamins or supplements to increase endurance (p < 0.05).

CONCLUSION: Based on the result, the community should continue to improve the COVID-19 prevention practices in breaking the chain of transmission.

African Shovel-snout snakes (ProsymnaGray, 1849) are small, semi-fossorial snakes with a unique compressed and beak-like snout.Prosymnaoccur mainly in the savanna of sub-Saharan Africa. Of the 16 currently recognised species, four occur in Angola:Prosymna ambiguaBocage, 1873,P. angolensisBoulenger, 1915,P. frontalis(Peters, 1867), andP. visseriFitzSimons, 1959. The taxonomical status and evolutionary relationships ofP. angolensishave never been assessed due to the lack of genetic material. This species is known to occur from western Angola southwards to Namibia, and eastwards to Zambia, Botswana and Zimbabwe. The species shows considerable variation in dorsal colouration across its range, and with the lower ventral scales count, an ‘eastern race’ was suggested. In recent years,Prosymnamaterial from different parts of Angola has been collected, and with phylogenetic analysis and High Resolution X-ray Computed Tomography, the taxonomic status of these populations can be reviewed. Strong phylogenetic evidence was found to include theangolensissubgroup as part of the largersundevalligroup, and the existence of three phylogenetic lineages within theangolensissubgroup were identified, which each exhibit clear morphological and colouration differences. One of these lineages is assigned to the nominotypicalP. angolensisand the other two described as new species, one of which corroborates the distinct eastern population previously detected. These results reinforce that a considerable part of Angolan herpetological diversity is still to be described and the need for further studies.

Objective

Delivering person-centered care in individuals with knee osteoarthritis (OA) necessitates consideration of other chronic conditions that frequently co-occur. We sought to understand the extent to which arthritis therapists consider type 2 diabetes mellitus (T2DM) when treating persons with knee OA and concomitant T2DM, and barriers to doing so.

Methods

We conducted 18 semistructured telephone interviews with arthritis therapists working within a provincially funded arthritis care program (Arthritis Society Canada) in Ontario, Canada. We first analyzed interviews deductively using the Theoretical Domains Framework (TDF) to comprehensively identify barriers and enablers to health behaviors. Then, within TDF domains, we inductively developed themes.

Results

We identified 5 TDF domains as prominently influencing the behavior of arthritis therapists considering concomitant T2DM when developing a knee OA management plan. These were as follows: therapists’ perceived lack of specific knowledge around comorbidities including diabetes; the lack of breadth in skills in behavioral change techniques to help patients set and reach their goals, particularly when it came to physical activity; variable intention to factor a patient’s comorbidity profile to influence their treatment recommendations; the perception of their professional role and identity as joint focused; and the environmental context with lack of formalized follow-up structure of the current Arthritis Society Canada program that limited sufficient patient monitoring and follow-up.

Conclusion

Within the context of a Canadian arthritis program, we identified several barriers to arthritis therapists considering T2DM in their management plan for persons with knee OA and T2DM. These results can help inform strategies to improve person-centered OA care and overall health outcomes.
Quand la parentalité devient une souffrance : comprendre la puissance du burn out parental
Authors: Guillier Elsa
Published: September 2022

Bien que 5 à 6 % des parents soient touchés par le burn out parental, la problématique est encore méconnue autant du grand public que des professionnels de santé. Cet article présente les symptômes permettant de l’identifier, le processus qui le caractérise ainsi que les conséquences auxquelles sont confrontées des familles entières. En libérant la parole des parents concernés et en travaillant à un meilleur équilibre entre les ressources et les stresseurs liés à la parentalité, le professionnel pourra avoir un impact positif important dans l’accompagnement des parents épuisés.
Surcharge parentale et stratégies de coping chez les parents d’enfants autistes
Authors: Chawki Léa , Cappe Émilie
Published: September 2022

L’accompagnement et le soutien des parents d’enfants autistes constituent aujourd’hui une nécessité clinique et scientifique majeure, encouragée par la Stratégie nationale pour l’autisme (2018-2022). Les parents d’enfants autistes représentent une population vulnérable au stress, aux troubles anxio-dépressifs et au burn out parental. Les stratégies de coping s’avèrent être un facteur de protection nécessaire à l’amélioration de leur qualité de vie et de leur bien-être.

Recherches participatives et épistémologies radicales : un état des lieux
Authors: Godrie Baptiste , Juan Maïté , Carrel Marion
Published: September 2022

Cette introduction présente un dossier faisant état des recherches participatives contemporaines reposant sur des épistémologies radicales. Celles-ci interrogent les conceptions hégémoniques et les protocoles conventionnels de production de la science en lien avec les inégalités de pouvoirs et de savoirs structurant les inégalités sociales. En mettant l’accent sur des démarches de coopération entre chercheur·es de carrière et chercheur·es profanes s’inscrivant dans une double perspective de pluralisme épistémologique et de lutte contre les oppressions, les recherches participatives radicales assument des prétentions épistémologiques et politiques subversives. L’introduction revient sur les racines historiques de cet appel à briser le monopole de la recherche et analyse les différentes dimensions de cette radicalité (méthodologique, éthique, politique). Elle explore ensuite la manière dont les questions cruciales posées par ces démarches ont été abordées, en matière de critères de scientificité, d’instrumentalisation, de réflexivité ou encore d’usage du registre de l’oralité et des émotions. Elle interroge, enfin, l’actualité de cette posture radicale et analyse les raisons pour lesquelles elle se serait émoussée avec le temps. Que ce soit à l’échelle des politiques publiques, des structures universitaires ou des activités de recherche, un ensemble de phénomènes concourt à la rareté des recherches participatives radicales.
Femmes rurales en mouvement : une démarche épistémologique féministe décoloniale au moyen du film participatif
Authors: Santana Verônica , Prévost Héloïse
Published: September 2022

Comment investir le processus d’ empowerment dans une perspective féministe décoloniale ? Comment mettre en œuvre une démarche épistémologique et méthodologique dans une collaboration entre une universitaire et un mouvement social ? Cet article présente l’expérience de la co-construction, coréalisation, coproduction et codiffusion d’un film participatif – Mulheres rurais em movimento [Femmes rurales en mouvement] – par une chercheuse française et des femmes rurales militantes brésiliennes. En imbriquant la réflexion sur l’androcentrisme et la colonialité, il a été question à travers ce projet d’agir sur les processus d’invisibilisation sociale et sur la négation des savoirs des femmes rurales.
