Due to its benefits and superior capabilities, composite laminate is one of the most widely utilized materials today. With the use of this cutting-edge technology, the world will be less dependent on the use of traditional materials, particularly metal. In the current work, the behaviour of laminated composite gear with different fibre reinforcing configurations is covered. For the current FE formulation, first-order shear deformation theory (FSDT) is used. The focus of fibre orientation on gear stress behaviour is highlighted in the current work. In the current FE formulation, which is a new development in the field of composite gears and deflection behaviour of the composite gear, focus is placed on the accurate computation of material properties with respect to fibre orientation in gears.
Disfungsi Peran Satgas Anti Mafia Bola Dalam Memberantas Match Fixing Sepakbola Indonesia
Authors: Zulhidayat Muhammad
Published: September 2022

Sepak bola adalah olahraga paling populer di Indonesia. Indonesia sendiri, sudah memiliki aturan tentang olahraga dalam pasal 29 ayat 2 undang-undang nomor 3 tahun 2005 tentang sistem olahraga nasional. Olahraga harus menghindari segala macam pengaturan pertandingan oleh mafia sepak bola. Namun, di Liga 2 Indonesia beberapa waktu lalu. Kasus pengaturan skor akhirnya membuat heboh sepak bola Indonesia. Hal ini membuat PSSI memutuskan untuk membuat kesepakatan dengan Mabes Polri untuk membuat MOU. Tindak lanjut dari MOU tersebut menghasilkan keputusan untuk membentuk satgas anti mafia bola sesuai dengan perintah Kapolri No.3678 Tahun 2021. Penelitian ini akan mengkaji peran dan fungsi satgas anti mafia bola dalam memberantas mafia sepak bola di Indonesia. Penelitian ini menggunakan metode penelitian yuridis normatif. Hasil pembahasan dalam penelitian ini menjunjukkan bahwa, pertama, telah terjadi disfungsi pada satuan tugas anti mafia bola, karena laporan dan fungsi satuan tugas anti mafia bola tidak terlihat dan hanya bersifat simbolis, hal ini terlihat dari tidak adanya tindak lanjut terhadap laporan pertandingan kepada pihak kepolisian, padahal match fixing adalah organize crime. Kedua Eksistensi Satgas anti mafia bola juga menjadi persoalan, hal ini dikarenakan satgas anti mafia bola hanya bersifat ad hoc dan eksistensi yuridisnya juga hanya berupa perpanjangan surat edaran kapolri. Bagian penutup yakni, pertama, pemerintah harus membuat aturan dalam undang-undang atau peraturan pemerintah untuk memberantas mafia sepak bola di Indonesia. Kedua, PSSI harus memberikan sanksi tegas kepada mafia bola sehingga menimbulkan efek jera.
Feature Distribution Matching for Federated Domain Generalization
Authors: Sun Yuwei , Chong Ng , Ochiai Hideya
Published: September 2022

Multi-source domain adaptation has been intensively studied. The distribution shift in features inherent to specific domains causes the negative transfer problem, degrading a model’s generality to unseen tasks. In Federated Learning (FL), learned model parameters are shared to train a global model that leverages the underlying knowledge across client models trained on separate data domains. Nonetheless, the data confidentiality of FL hinders the effectiveness of traditional domain adaptation methods that require prior knowledge of different domain data. We propose a new federated domain generalization method called Federated Knowledge Alignment (FedKA). FedKA leverages feature distribution matching in a global workspace such that the global model can learn domain-invariant client features under the constraint of unknown client data. FedKA employs a federated voting mechanism that generates target domain pseudo-labels based on the consensus from clients to facilitate global model fine-tuning. We performed extensive experiments, including an ablation study, to evaluate the effectiveness of the proposed method in both image and text classification tasks using different model architectures. The empirical results show that FedKA can achieve performance gains of 8.8% and 3.5% in Digit-Five and Office-Caltech10, respectively, and a gain of 0.7% in Amazon Review with extremely limited training data. Moreover, we studied the effectiveness of FedKA in alleviating the negative transfer of FL based on a new criterion called Group Effect. The results show that FedKA can reduce negative transfer, improving the performance gain via model aggregation by 4 times.

The specificity of a corporate dispute is that the disagreements of its participants are resolved by adoption or decisions at a general meeting of the corporate organization.
Sharing Economy аnd Consumer Legal Status
Authors:   Russian State University of Justice (Moscow), Anatolij V. Efimov
Published: September 2022

The development of the sharing economy blurs the line between the personal use of property and the professional activity of providing property for the use of others. Because of this, there are problems of qualifying this activity as entrepreneurial and extending to property owners the norms that regulate the activities of “classical” entrepreneurs. As a result, this actualizes the problem of the certainty of the legal status of consumers. The purpose of the study is to assess the relationship between the nature of the activities of property owners as participants in the sharing economy and the legal status of consumers. When writing this article, general scientific methods (system, functional, group of logical methods) and special legal methods (formal legal, legal modeling method) were applied. This article describes the main approaches to understanding the sharing economy. At the same time, it is concluded that any model of the sharing economy corresponds to a certain legal regulation. Particular attention is paid to consumers. Thus, it is substantiated that the legal status of consumers depends not only on their personality and consumption goals, but also on the legal status of their counterparties, on the legal regime of the latter’s activities. In this regard, the problem is indicated that the qualification of activities for the provision of property is carried out ex post, and the parties cannot assess their legal status in advance. In order to solve this problem, it is proposed to determine the legal status of participants in the sharing economy ex ante on the basis of taking into account their economic indicators within the framework of Internet platforms.

Revision of Court Decisions in Civil Proceedings During the New Economic Policy Period
Authors:   North-West Branch of Russian State University of Justice (St. Petersburg), Olina I. Filonova
Published: September 2022

The institution of revision in civil procedure is designed to ensure the achievement of the legality and validity of court decisions. The purpose of the work is to study the historical experience of revising court decisions that have entered into legal force in civil proceedings during the period of the new economic policy. Comparative historical and formal legal research methods are used. As a result of the study, the following conclusions were made. In 1923, the course was in effect for the implementation of the principle of a single court, and only the Supreme Court of the RSFSR was vested with the power to review court decisions that had entered into legal force in civil proceedings. In 1930, a course towards decentralization appeared, and the lower courts were vested with the right to review. During the NEP period, the norms of the legislation on the revision of court decisions were repeatedly changed. Circulars of the People’s Commissariat of Justice of the RSFSR and clarifications of the Supreme Court of the RSFSR were of leading importance for law enforcement practice. Legislatively enshrined two forms of revision of court decisions that entered into legal force in civil proceedings: on newly discovered circumstances and in the order of prosecutor’s supervision. They differed in terms of limitation period, grounds and methods of initiating a revision. Distinctive features of the prosecutor’s protest were: no statute of limitations; grounds for protest – a material violation of laws and a real or potential violation of the interests of the state or workers when the court decision is upheld. The list of subjects for initiating the review was not limited to the parties and the prosecutor; this right was also granted to the Presidium of the All-Russian Central Executive Committee, the Presidium of the Supreme Court, and the Civil Cassation Board of the Supreme Court of the RSFSR, the People’s Commissar of Labor.

Influence of the Positions of the Constitutional Court of the Russian Federation and the European Court of Human Rights on the Сontent of the Adversarial Principle in Criminal Procedure Law
Authors:   Moscow City Court, Moscow, Russia, Vladimir S. Akimov
Published: September 2022

In the context of the constant development of the practice of the Constitutional Court of the Russian Federation and the European Court of Human Rights, the relevance of the issue of its place and role in the legal system inevitably increases. The principle of competitiveness of the parties was introduced in Russian criminal proceedings more than 150 years ago, but its implementation was directly related to the existing legal system of a particular period. Despite the significant contribution of law enforcement practice to the development of theoretical provisions on the content of the adversarial principle, many positions characterizing this principle remain controversial. Until now, there is no consensus on the limits of its manifestation and the relationship with other principles, as well as the appointment of criminal proceedings. The purpose of the work is to develop a practical understanding of the content of the adversarial nature of a criminal case in court from the standpoint of the highest judicial instances. This goal predetermined the need to identify the existing provisions formulated in the decisions of the Constitutional Court of the Russian Federation and the European Court of Human Rights regarding the determination of the adversarial nature of the parties in the course of criminal proceedings. As a methodological basis, the work used formal-logical methods (induction, deduction, analysis, synthesis, hypothesis, analogy), ascent from the abstract to the concrete, as well as some special scientific methods: historical, comparative-legal, technical-legal. The theoretical significance of the work lies in the formulated proposals that can be used in improving the current criminal procedure legislation and in further theoretical developments of the adversarial principle in criminal proceedings, as well as in the law enforcement activities of the courts.

System Architecture and Planetary Obliquity: Implications for Long-term Habitability
Authors: Vervoort Pam , Horner Jonathan , Kane Stephen R. , Kirtland Turner Sandra , Gilmore James B.
Published: September 2022

In the search for life beyond our solar system, attention should be focused on those planets that have the potential to maintain habitable conditions over the prolonged periods of time needed for the emergence and expansion of life as we know it. The observable planetary architecture is one of the determinants for long-term habitability as it controls the orbital evolution and ultimately the stellar fluxes received by the planet. With an ensemble of n-body simulations and obliquity models of hypothetical planetary systems, we demonstrate that the amplitude and period of the eccentricity, obliquity, and precession cycles of an Earth-like planet are sensitive to the orbital characteristics of a giant companion planet. A series of transient, ocean-coupled climate simulations show how these characteristics of astronomical cycles are decisive for the evolving surface conditions and long-term fractional habitability relative to the modern Earth. The habitability of Earth-like planets increases with the eccentricity of a Jupiter-like companion, provided that the mean obliquity is sufficiently low to maintain temperate temperatures over large parts of its surface throughout the orbital year. A giant companion closer in results in shorter eccentricity cycles of an Earth-like planet but longer, high-amplitude, obliquity cycles. The period and amplitude of obliquity cycles can be estimated to first order from the orbital pathways calculated by the n-body simulations. In the majority of simulations, the obliquity amplitude relates directly to the orbital inclination whereas the period of the obliquity cycle is a function of the nodal precession and the proximity of the giant companion.

Published: September 2022

We investigate the internal kinematics of the young star-forming region NGC 346 in the Small Magellanic Cloud (SMC). We used two epochs of deep F555W and F814W Hubble Space Telescope Advanced Camera for Surveys observations with an 11 yr baseline to determine proper motions and study the kinematics of different populations, as identified by their color–magnitude diagram and spatial distribution characteristics. The proper motion field of the young stars shows a complex structure with spatially coherent patterns. NGC 346’s upper main sequence and pre-main sequence stars follow very similar motion patterns, with the outer parts of the cluster being characterized both by outflows and inflows. The proper motion field in the inner ∼10 pc shows a combination of rotation and inflow, indicative of inspiraling motion. The rotation velocity in this regions peaks at ∼3 km s−1, whereas the inflow velocity peaks at ∼1 km s−1. Subclusters and massive young stellar objects in NGC 346 are found at the interface of significant changes in the coherence of the proper motion field. This suggests that turbulence is the main star formation driver in this region. Similar kinematics observed in the metal-poor NGC 346 and in the Milky Way’s star-forming regions suggest that the differences in the cooling conditions due to different amounts of metallicity and dust density between the SMC and our galaxy are too small to alter significantly the process of star cluster assembly and growth. The main characteristics of our findings are consistent with various proposed star cluster formation models.
Ram Pressure Stripping of the Multiphase ISM: A Detailed View from TIGRESS Simulations
Authors: Choi Woorak , Kim Chang-Goo , Chung Aeree
Published: September 2022

Ram pressure stripping (RPS) is a process that removes the interstellar medium (ISM) quickly, playing a vital role in galaxy evolution. Previous RPS studies have treated the ISM as single-phase or lack the resolution and physical processes to properly capture the full multiphase ISM. To improve this simplification, we introduce an inflowing, hot intracluster medium (ICM) into a self-consistently modeled ISM in a local patch of star-forming galactic disks using the TIGRESS framework. Our simulations reveal that the workings of RPS are not only direct acceleration of the ISM by ICM ram pressure but also mixing-driven momentum transfer involving significant phase transition and radiative cooling. The hot ICM passes through the low-density channels of the porous, multiphase ISM; shreds the cool ISM; and creates mixing layers. The ICM momentum is transferred through the mixing layers while populating the intermediate-temperature gas and radiating thermal energy away. The mixed gas extends beyond galactic disks and forms stripped tails that cool back unless the ICM fluxes are large enough to prevent cooling until they escape the simulation domain. The mixing-driven momentum transfer predicts that the more ICM mixes in, the faster the ISM moves, resulting in the anticorrelation of outflow velocity and gas metallicity of the stripped ISM. The compression of the ISM disks due to the ICM ram pressure enhances star formation rates up to 50% compared to the model without ICM. With the ICM ram pressure higher than the disk anchoring pressure, star formation is quenched within ∼100 Myr.

We present the results of optical and near-IR spectroscopy and multicolor photometry of the emission-line star MWC 645, which exhibits the B[e] phenomenon. The presence of positionally variable absorption lines of a cool star detected for the first time indicates that the object is a binary system. Using a combination of the photometric and spectroscopic data as well as the Gaia EDR3 distance (D = 6.5 ± 0.9 kpc), we disentangled the components’ contributions and estimated their surface temperatures and luminosities (18, 000 ± 2000 K and 4250 ± 250 K, log L/L
⊙ = 4.0 ± 0.5 and 3.1 ± 0.3 for the hot and cool components, respectively). Quasi-cyclic short-period (months) and long-period (∼4 yr) photometric variations were detected in both optical and near-IR regions, and are most likely due to variable circumstellar extinction. Our analysis suggests that MWC 645 is a member of the FS CMa group. The object’s properties can be described by an evolutionary model of a close binary system that currently undergoes a nonconservative mass transfer between intermediate-mass stars (e.g., 7 M
⊙ + 2.8 M
⊙).

Intervals of intense electromagnetic, broadband plasma waves are reported in the near-Sun solar wind. These waves are identified as kinetic Alfvén waves (KAWs), based on comparison between data and theory for their observed electric- to magnetic-field ratio, and magnetic compressibility, as a function of frequency. In contrast to KAW observations at 1 au, KAWs in the near-Sun solar wind are found to be spatially inhomogeneous, preferentially occurring where the ambient magnetic field experiences strong deviations from the Parker spiral direction, including during magnetic switchbacks and clusters of switchbacks. To the extent that turbulent fluctuations in the solar wind at small scales are characterized as KAWs, the observations reported here create an expectation that KAW-driven particle heating should also be inhomogeneous in the near-Sun solar wind, being strongest in regions of intense KAWs. Finally, a discrepancy between KAW observation and theory is identified at frequencies two decades above the frequency where kinetic effects begin to manifest, and possible origins of this discrepancy are considered.

Dynamic analysis of a predator-prey state-dependent impulsive model with fear effect in which action threshold depending on the prey density and its changing rate
Authors: Wu Yazhi , Tang Guangyao , Xiang Changcheng
Published: September 2022

In ecology, the impact of predators goes beyond killing prey, the mere presence of predators reduces the ability of prey to reproduce. In this study, we extend the predator-prey model with fear effect by introducing the state-dependent control with a nonlinear action threshold depending on the combination of the density of prey and its changing rate. We initially defined the Poincaré map of the proposed model and studied its fundamental properties. Utilizing the properties of the Poincaré map, periodic solution of the model is further investigated, including the existence and stability of the order-1 periodic solution and the existence of the order-k ($ k \ge 2 $) periodic solutions. In addition, the influence of the fear effect on the system's dynamics is explored through numerical simulations. The action threshold used in this paper is more consistent with the actual growth of the population than in earlier linear threshold studies, and the results show that the control objectives are better achieved using the action threshold strategy. The analytical approach used in this study provided several novel methods for analyzing the complex dynamics that rely on state-dependent impulsive.

Of late, Augmented Reality (AR) has become one of the important tools in teaching and learning, which is made evident by an increasing number of studies focusing on such technology over the past few years. However, studies focusing on the design of AR learning tools or applications for young children have been seriously lacking. Therefore, this paper provides a detailed account of the findings of a study carried out by the authors in which the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) method was used to select and critically review related articles from two leading databases, namely Scopus and Web of Science (WoS) databases. Overall, 16 articles relating to the design and development of AR learning applications were selected from such databases, which revealed five themes and nine subthemes as follows: (1) information design (with three sub-themes), (2) interface design (with one subtheme), (3) interaction design (with two subthemes), (4) imagination (with two subthemes), and (5) immersion (with one subtheme). As such, all five themes relating to the design aspects of AR learning applications need to be carefully addressed and considered in developing efficacious AR learning applications for young children. In summation, the findings of this study based on the systematic review of the current AR literature can be used as a guideline for developers of AR learning applications to ensure their products can be both efficacious and entertaining, the impact of which can surely improve children’s learning performance, motivation, and interest.

Predictive Modelling for Financial Fraud Detection Using Data Analytics
Authors: Moroke Ntebogang Dinah , Makatjane Katleho
Published: September 2022

Financial fraud remains one of the most discussed topics in literature. The financial scandals of Enron, WorldCom, Qwest, Global Crossing, and Tyco resulted in approximately 460 billion dollars of loss. The detection of financial fraud, therefore, has become a critical task for financial practitioners. Three factors determine the likelihood of fraud occurrence, including pressure, opportunity, and rationalization. The core of these factors lies in people's beliefs and behaviour. Due to the unpredictability and uncertainty in fraudsters' incentives and techniques, fraud detection requires a skill set that encompasses both diligence and judgment. Big data technologies have had a huge impact on a wide variety of industries because they tend to be ubiquitous, starting in the last decade and continuing today.
Wing Lift Enhancement from Aft Rotor Induced Suction
Authors:   Rensselaer Polytechnic Institute, Healy Richard , Gandhi Farhan
Published: September 2022

This study examines the aerodynamic interactions of rotor-wing units in which lifting rotors are mounted below and behind a wing. The rotor-wing units are simulated using CFD, and their performance is compared to isolated rotors and wings in order to understand the interference effects. Simulations are performed using the commercial Navier Stokes solver, AcuSolve®, with a delayed detached eddy simulation (DDES) model. Rotor-wing units with three wing incidence angles (7°, 10° and 13°) as well as three rotor disk loadings (6, 9 and 12 lb/ft2) are considered. By simulating the flow and comparing the pressure distribution around an isolated wing to one with the rotor installed, the rotor is seen to introduce a low pressure region that extends over the wing’s top surface. The additional rotor-induced suction on the top surface of the wing augments wing lift by up to 134%, and provides some stall mitigation at 13° incidence angle. Suction near the leading edge of rotor-installed wings also counters the nominal wing drag, introducing a net propulsive force on the wing at all incidence angles considered. On the rotor, downwash induced by the wing’s bound circulation introduces a rotor thrust deficit up to 10% nominal thrust and torque penalty up to 4% nominal torque. Despite the rotor performance penalties, interactions between the rotor and wing lead to equivalent lift to drag ratio improvements ranging from 47%- 52% over a range of wing angles. As disk loading is increased, the rotor-induced suction strengthens, extending the 66% wing lift increment at 6lb/ft2 up to 115% at 12 lb/ft2. These results suggest that the interactional aerodynamics associated with mounting a rotor below and behind a wing can introduce enhanced system performance over a range of wing angles and rotor loadings.
Rotorcraft Pitch-Surge Motion Cueing Requirements for a Simulated Offshore Approach Task
Authors:   University of Liverpool, Roscoe Josephine , White Mark D. , Hodge Steven J. , Padfield Gareth D.
Published: September 2022

The paper describes findings from a rotorcraft pitch-surge motion fidelity study conducted in the University of Liverpool’s HELIFLIGHT-R flight simulator. Two test pilots flew a decelerating offshore approach maneuver during which a disturbance was encountered. The approach was flown without simulator motion as a ‘baseline’ case and with simulator motion using different combinations of pitch and surge motion filter coefficients. The pilot-awarded handling qualities and motion fidelity ratings for each motion configuration, and task performance and control activity data were gathered. The study concluded that for the approach flown without motion, the dominant driver of workload was vertical rate control, and this was most significant at airspeeds less than 50kts. When the approach was flown with a disturbance, good motion cues were judged to be achieved through careful selection of the pitch and surge motion filter gains, the most favored being a surge gain equal to that of the pitch gain. Additionally, pilots preferred pitch-surge cues that were in the correct sense, rather than being particularly ‘strong’. Increasing the pitch gain was only beneficial with a moderate level of pitch break frequency of 0.4 rad/s.
Impact of Capital Structure on Firm Performance of Food and Beverage Listed Companies on the Stock Exchange of Vietnam

Published: September 2022

This study tested the relationship between capital structure and firm performance. Data were collected from 41 food and beverage companies listed on the Vietnam Stock Exchange from 2017 to 2021. Three variables were used to measure the performance of each company, including ROA, ROE and EPS. The ratio of total debt to total assets (DA), total debt to total equity (DE), short-term debt to total assets (SDTA) and long-term debt to total assets (LDTA) are the key factors. for capital structure. Besides, growth rate (GROWTH) and company size (SIZE) are also applied in the model as control variables. As a result, most of the capital structure variables have a negative effect on each of the firm’s performance variables. It is noteworthy that this study also illustrates the negative correlation between ROE and capital structure shown, which was thought to be insignificant in many previous studies but also shows a negligible relationship between SDTA and SDTA. Moreover, ROE was rarely seen in previous studies. Furthermore, the research results also show a negligible impact on growth rate and a positive relationship between size and firm performance.
Advancing the understanding of the flipped classroom approach with students' perceptions of the learning environment: variation between academic disciplines
Authors: Ng Hilary , Lam Paul
Published: September 2022

Abundant research supports the benefits of the flipped classroom approach on learning outcomes. Yet how students evaluate the flipped learning environment remains largely unknown. The present study aims to investigate 1) the students’ perceptions of their flipped learning and 2) whether disciplinary differences can be observed in students’ perceptions. Drawing upon the theoretical framework outlined in Brame (2013), our findings illustrated that students (N = 407) from different disciplines do vary their evaluation of the flipped learning environment. Those whose academic disciplines related to the application of knowledge evaluated the four components – exposure, incentive, assessment, and activities – more positively than those whose academic disciplines focus more on theoretical exploration. It is noteworthy that how subject knowledge is developed does not influence perception of the flipped learning environment. Such findings can supplement the traditional outcome-based approach of flipped classroom research by understanding the learning environment. All in all, the findings can point to practical and theoretical implications for designing a flipped classroom environment, highlighting the needs in designing the learning environment.
Interrogating a collaborative instructional approach to academic literacy: the missing link in supporting students’ language learning
Authors: Tang Kum Khuan , Wong Derek , Ling Lee Gek
Published: September 2022

In Covid-19’s ‘new normal’ academics have been urged to tear down subject silos and approach teaching collaboratively with renewed interest and increased urgency. An example of this can be found in curriculum-integrated academic literacy instruction which is based on the collaboration between language and content instructors. Case studies frequently report barriers to engaging content instructors in supporting students’ language learning. However, the internal conflicts of language instructors are under-represented: little is known about their subjective experiences and emotions as they go about negotiating and accommodating a collaborative instructional approach. This paper undertakes a narrative inquiry into three language instructors’ stories of teaching discipline-specific academic literacy. In bringing to the fore their reflexive voices on authority, agency and feelings of student resistance, it explores themes around identity and collaboration and underlines a critical missing link that mediates faculty collaboration and student learning. Humanising faculty development and venturing into scholarly enquiry are then proposed as potential ways to empower language instructors to manage the emotional complexities in their collaborative engagements.

Published: September 2022

Kentsel mekanda yüksek binalar ve sokakların oluşturduğu kent formu kent kanyonu olarak tanımlanmaktadır. Bu mekanların geometrik özelliklerinden kaynaklı unsurlar dış mekan ısıl durumu üzerinde etkiye sahiptir. Bu yüzden bu çalışmada sıcak-nemli Adana kent dokusunda yer alan Kurtuluş Mahallesi’ndeki kent kanyonlarının uydu görüntüleri aracılığı ile ısıl durumlarının tespit edilmesi amaçlanmıştır. Çalışmanın yöntemi 4 basamaktan oluşmaktadır. (i) Landsat 8 termal görüntüler aracılığı ile çalışma alanı yer yüzeyi sıcaklık (YYS) durumunun belirlenmesi, (ii) çalışma alanında yer alan kanyonların geometrik özellikleri (yönelim ve bina yüksekliği/sokak genişliği oranı) doğrultusunda sınıflanması, (iii) YYS ve geometrik özellikler arasındaki ilişkinin istatistiksel olarak belirlenmesi, (iv) bulgular doğrultusunda gelecek kent planlarına yansıtılabilir önerilerin geliştirilmesidir. Çalışmada en düşük YYS’ye sahip olan alanlar gölge oranının yüksek olduğu derin kent kanyonları ve yoğun kanopi dokusuna sahip yeşil alanlar olarak belirlenmiştir (34,0-35,5℃). En yüksek YYS’ye sahip alanlar ise güneş maruziyetinin yüksek ve gölge oranının düşük olduğu istasyon alanı, stadyum, vb. kentsel mekanlardır (36,5-37,2℃). Derin kanyonlarda D-B yönelimli alanların K-G yönelimli alanlardan daha düşük YYS’ye sahip olarak birbirlerinden istatistiksel olarak ayrılmaktadır (p
Prevention and risk assessment of cardiovascular events in a population of patients with psoriasis and psoriatic arthritis

Psoriasis is a chronic, inflammatory, often relapsing disease that is frequently associated with other diseases of similar pathogenesis. The multi-morbidity in the psoriasis population significantly impedes both diagnosis and implementation of appropriate preventive measures. However, the common denominator for this group of diseases is the inflammatory process that initiates the appearance of subsequent symptoms and health consequences, most of which can be avoided or alleviated by modifying the patient’s lifestyle and incorporating appropriate treatment. Health consequences associated with systemic inflammation include cardiovascular incidents and other cardiometabolic diseases. 

This article was based on available publications on the onset, incidence, and prevention of cardiovascular disease in the psoriasis patient population.
Ziya Gökalp Felsefesinde İrade Özgürlüğünün İmkânı ve Değerlerin Doğası: Hüsün ve Kubuh Teorisi
Authors: Demirci Osman
Published: September 2022

ÖzBu makalede Ziya Gökalp’in hüsün ve kubuh teorisi bağlamında irade özgürlüğü ve değer yargıları hakkındaki görüşlerinin bir bütünlük içinde ele alınarak tutarlılığı yönünden değerlendirilmesi amaçlanmaktadır. Geleneksel kelam düşüncesindeki iyi ve kötünün akılla mı yoksa vahiyle bilineceği tartışmasına yeni bir bakış açısı getiren düşünür, pozitivist felsefenin etkisiyle bu konuda belirleyici unsurun toplum olduğunu iddia edecektir. Düşünürün, gerek irade özgürlüğü gerekse değerler konusundaki görüşleri toplum merkezli felsefesine göre şekillenmektedir. Ona göre insan iradesini aşan değer yargılarının yegâne dayandığı yer toplumdur. Toplum hem insanın özgürlüğünü sınırlandırmada hem de onun değer yargılarını belirlemektedir. Gökalp’te gerek irade özgürlüğünün toplumsal hayattaki imkânı gerekse değerler karşısındaki bireyin pasif konumu oldukça vurucu bir şekilde ele alınmaktadır.
