Authors:   Lviv Polytechnic National University, Lytvyn Vasyl , Mushasta Solomiya ,   Lviv Polytechnic National University
Published: August 2023

This paper investigates the problem of embedding features used in datasets for training neural networks. The use of embeddings increases the performance of neural networks, and therefore is an important part of data preparation for deep learning methods. Such a process is based on semantic metrics. It is proposed to use ontologies of the subject areas to which the corresponding feature belongs for embedding. This work developed such a method and investigated its use for the task of categorizing text documents. The research results showed the advantage of the developed method.

Authors:   Lviv Polytechnic National University, Kravets Petro , Yaremko Natalia ,   Lviv Polytechnic National University
Published: August 2023

This paper describes the requirements for the project of an information sales system on the platform of charitable online auctions, which offers a fundamentally new way to sell valuable property, such as real estate or transport. The designed information system is a non-standard solution for the implementation of auction sales, since in economically unstable times it is intended to become an alternative way for sellers to expose their property as a lot; to play a lot between the participants of the auction and give a chance to low-income segments of the population to become owners of valuable property for a relatively small amount of the bid in the auction; pay part of the collected amount in favor of charitable foundations for which users will vote when participating in the auction; enrich the state budget by paying taxes on the purchase and sale procedure. The expediency of creating such an information system was assessed on the basis of comparing it with the existing prototypes. To substantiate the relevance of the project, a system of experimental evaluation of the characteristics of the designed system and its analogues has been developed according to a number of criteria. A number of advantages and critical differences of the system project have been identified. On the basis of the project management method S.M.A.R.T. the goals of creating an information system are formulated and a list of tasks to achieve them is determined. Structural, functional, informational, business and client requirements for the project are outlined. The main means of developing an IT project in TypeScript on the Node.js and Angular platforms are indicated. Integration of the information system with the Fondy payment system to save proceeds from the auction is proposed. The risks of project implementation are identified and ways to minimize their impact are outlined.

Authors:   Lviv Polytechnic National University, Kravets Petro , Tverdokhlib Yurii ,   Lviv Polytechnic National University
Published: August 2023

This paper describes an information system for monitoring and analyzing reviews on social networks to form recommendations for the purchase of goods. This system is designed to be used by customers to speed up and facilitate the search for the necessary products on e-commerce resources. Successful selection of a quality product according to the desired criteria is extremely important, as it saves search time and customer money. Analyzing comments on the network, the information system recommends the product if there is a preponderance of positive feedback on it. The purpose of the work, object and subject of research, scientific novelty and practical significance of the work are formulated. An analysis of the peculiarities of the studied subject area and known means of solving the problem was carried out. Systems used in online marketing were used as a prototype system for generating recommendations based on feedback analysis. Comparative characteristics of the system with analogues were conducted and it was determined that the system is unique, and its development is relevant, since known existing similar systems do not recommend products to users based on the feedback of other users. The general goal of system development is determined, the purpose, place of application of the system, development and implementation of the system are described. The criteria that are put forward when defining the goals are defined. Using the method of analysis of hierarchies, it was determined that the type of product being developed is a decision support system. A conceptual model of the system has been developed. Project requirements are modeled – business requirements, user requirements, functional requirements, non-functional requirements. Input and output data of the system are defined. The decision-making system is based on an algorithm for sentiment analysis of social networks users using the logistic regression method. Logistic regression is one of the most common machine learning algorithms that is easy to implement for classifying sets of linearly separable clusters of data. It quickly learns on large data sets and guarantees reliable results. Economic, functional, financial and time effects should be expected from the implementation of such a recommendation system.

Molière critique de son œuvre : La Critique de L’École des femmes et L’Impromptu de Versailles
Authors: Leopizzi Marcella
Published: August 2023

Dans cet article, nous allons analyser les thèmes méta-théâtraux contenus dans La Critique de L'École des femmes et dans L’Impromptu de Versailles, afin de faire ressortir l’activité métafictionnelle de Molière développée dans ces deux pièces. En examinant ses théories sur l’esthétique théâtrale et sur le débat concernant la tragédie et la comédie ainsi que la fidélité aux règles, nous visons à démontrer le rôle actif que Molière joue au sein des querelles théâtrales par le biais du théâtre dans le théâtre en tant que juge de ses propres œuvres si ce n’est en tant que défenseur de ses pièces et du genre comique. De plus, en soulignant son apport à la critique littéraire, nous nous proposons de mettre en évidence aussi que, de par ces deux pièces, Molière attaque les vices des mœurs de la société mondaine de son temps et tout particulièrement l’affectation, la vanité, la pédanterie, la fausse pruderie, la dévotion hypocrite dans une optique d’édification universelle à caractère intemporel et qui plus est dans des finalités éducatives émancipatrices vis-à-vis de la condition féminine.
Theorizing Collective Trauma and Identity-Threat in Select Stories from Deshbhager Galpa: Tripura
Authors: Chakraborty Jagriti , Chakrabarty Dr. Madhumita
Published: August 2023

Memory is a complex phenomenon that reaches out to far beyond what normally constitutes a historian's archives, for memory is much more than what the mind can remember or what objects can help us document about the past. There are then two aspects to this memory that concern us here: the sentiment of nostalgia and the sense of trauma, and their contradictory relationship to the question of the past. A traumatised memory has a narrative structure which works on a principle opposite to that of any historical narrative. At the same time, however, this memory, in order to be the memory of a trauma, has to place the Event - the cause of the trauma, in this case, Partition of 1947 in the context of Tripura-within a past that gives force to the claim of the victim. This has to be a shared past between the narrator of the traumatic experience and the addressee of the narration. Yet it cannot be a historicist version of the past, one that aims to diffuse the shock of the traumatic by explaining away the element of the unexpected. Hence the introductory segment of the paper might highlight the facts related to Tripura Bengalis, their arrival, and their stories of settlement. However, the purpose is to examine the psychological reactions to a traumatic event that affects an entire society; it does not merely reflect an historical fact, the recollection of a terrible event that happened to a group of people. The aim is to analyse the features of traumatic memories and, thus, how individuals construct and integrate their experiences and struggles through narratives. The chosen text is select stories from Deshbhagger Galpa:Tripura, a collection of short stories focusing on Nostalgia, Identity-crisis and Collective Trauma.

Negeri Sabah terdiri dalam kalangan penduduk berbilang suku kaum dan hidup dalam keadaan aman sentosa. Bertunjangkan kepelbagaian ritual etnik, maka wujudnya sistem kehakiman anak negeri yang bertanggungjawab mendengar dan menyelesaikan kes-kes berkaitan adat resam penduduk asli Sabah atau lebih dikenali sebagai peribumi tanpa mengira anutan agama. Secara dasarnya terdapat tiga sistem kehakiman yang berbeza di Sabah iaitu sistem kehakiman sivil, sistem kehakiman Syariah dan sistem kehakiman Anak Negeri Sabah. Objektif kertas konsep ini disediakan adalah untuk meninjau latar belakang sistem kehakiman Anak Negeri Sabah, menghuraikan kepentingan sistem kehakiman tradisional kepada masyarakat peribumi Sabah, mengenal pasti sumber undang-undang dan jenis-jenis hukuman yang dijatuhkan oleh Mahkamah Anak Negeri Sabah (MAN) khususnya hukuman denda sogit serta membincangkan hubung kait di antara denda sogit dan masyarakat peribumi Sabah. Sogit merupakan denda adat yang melibatkan upacara mengorbankanhaiwan ternakan seperti kerbau, ayam atau khinzir di samping upacara ritual bagi menenangkan semangat makhluk ghaib dan roh-roh. MAN mempunyai bidang kuasa menjatuhkan hukuman sogit seandainya berlaku perlanggaran terhadap mana-mana adat masyarakat peribumi Sabah melalui peruntukan undang-undang yang termaktub dalam Enakmen Mahkamah Anak Negeri Sabah 1992. Walau Sabah berdepan dengan arus pemodenan, namun masyarakat peribuminya masih mempertahankan tradisi adat resam, amalan pantang-larang dan juga hukuman sogit. Tuntasnya, kewujudan sistem kehakiman yang berteraskan amalan tradisi ini dilihat mampu memelihara kesantunan budi dan keluhuran adat dalam kalangan peribumi khususnya dan masyarakat setempat am nya.

«Hüte dich vor mir, Geliebter!» Zu Conrad Ferdinand Meyers Affektpoetik
Authors: Andermatt Michael
Published: August 2023

Conrad Ferdinand Meyer arbeitet in seinem historischen Erzählen mit starken Affekten. Liebe und Hass erscheinen in Extremform (Inzest, Mord und Verrat) und überlagern sich dabei mit dem zeitgenössischen Reizthema des Kulturkampfs (Nationalstaat vs. Kirche). Hass und Liebe sind mithin in Meyers Erzählen politisch-weltanschaulich überformt und gehen über die literarische Darstellung von Gefühlen hinaus. Der Beitrag macht deutlich, wie Meyer in seinem Erzählen über Stoffwahl, Figuren­charakterisierung und Spannungserzeugung eine Affektpoetik verfolgt, die mit ihren spezifischen Effekten die zeitgenössische Leserschaft emotionalisiert. Indem Liebe und Hass in Interaktion mit Politik und Weltanschauung treten, stellen sie im affektiven Transfer geltende Regelungen von Kirche, Staat und Gesellschaft zur Disposition.
«I am a non-natural mother». Maggie Gyllenhaal’s The Lost Daughter An interdisciplinary inquiry into love, hate and the overwhelming guilt of a mother
Authors: Baer Josette
Published: August 2023

I address the theme of «Love and Hate» with an analysis of Maggie Gyllenhall’s film The Lost Daughter (2021). The film’s plot is based on the novel by the same name by Italian writer Elena Ferrante, a pseudonym. Leda is a 48-year-old professor of translation and lives in Cambridge, close to Boston. It is unclear if she teaches at Harvard. She is divorced and had daughters Marta and Bianca early on while trying to embark on an academic career. While on a working holiday on a Greek island, Leda makes the acquaintance of a brash, brazen, and imposing clan from New York City that commands the beach for itself. Especially the young mother Nina takes a shine to the elder educated woman, who appears self-confident and independent. Confronted with Nina’s self-doubts about being a good mother, Leda is catapulted back into her memories of her love and hate for her daughters.

Hannah Arendt’s definition of love in her PhD dissertation Love and Saint Augustine and Plutarch’s definition of hate in his Moralia serve as the philosophical backbone of my analysis. In the conclusion, I address the political movement of «The Voluntary Extinction of Mankind» asking a moral question: Should one have children?

Road traffic injuries: psychological and social aspects
Authors: Petrova N. G.
Published: August 2023

Introduction. Despite the positive trend in recent years, the incidence of road traffic injuries and deaths from it remains high, significantly higher than in developed countries. The economic significance of the problem is determined by the high level of disability among the victims, and by the fact that a significant part of them are people of working age. The following factors contribute to the occurrence and certain outcomes of road accidents: people (behavior, health, psychological state of road users); vehicle condition; environment (road infrastructure); the state of organization of medical care for victims (including the possibility and readiness of participants and witnesses of road accidents to provide first aid). The objective was to analyze the level of driving culture and the readiness of drivers to provide first aid based on the results of self-assessment. Methods and materials. The main research method was a sociological survey, which was conducted on the basis of the Google Forms survey administration program. The survey was conducted among the population of St. Petersburg and the Leningrad region. The questionnaire developed for the study included 29 questions. All questionnaires were encrypted and processed using the Excel and Statistica 10 statistical applications. Results. Assessing their level of knowledge of the rules of the road, most of the respondents considered it as average (45.3 %) and above average (34.0 %). Only 7.5 % considered it as high. Every third (34.2 %) respondent was a participant in an road accident (including 4.9 % – road accidents with victims). 45.3 % of respondents assessed the level of driving culture as average; 39.6 % – rather low; and only 5.7 % – as rather high. The majority (83.0 %) of drivers always used seat belts. Among drivers with children, 11.8 % did not have special child restraints. 10.4 % of respondents did not have a first aid kit in their car. The readiness of drivers to provide first aid was low. Only 26.9 % of the respondents confidently answered that they could provide first aid for the victims. Conclusions. The problem of preventing road accidents and reducing mortality from them can only be solved using a systematic approach, including optimization of traffic organization, improvement of road infrastructure, condition of vehicles, improvement of the organization of medical care for victims, etc. However, the central place should be given to cultivating the culture of all road users, psychological readiness to comply with traffic rules, providing first aid.

Authors: EFTELİ Elçin , ÖZDEMİR Handan
Published: August 2023

Phlebitis is the inflammation of the tunica intima layer of the vein and is a common preventable complication of peripheral intravenous catheters (PIC). The aim of this study was to determine the rate of phlebitis development in patients with PIC implantation using the Visual Infusion Phlebitis Diagnostic Scale and to determine the associated factors. The study was conducted in the internal and surgical clinics of a public hospital between September 1, 2022 and February 1, 2023. The 'Patient Information Form', 'Peripheral Intravenous Catheter Evaluation Form' and 'Visual Infusion Phlebitis Diagnosis Scale' were used to collect the study data. In 30.3% of the patients with PIC, phlebitis developed and 48.9% of the phlebitis cases were grade 1. the variables such as sex and presence of a chronic disease did not affect the development of phlebitis. Phlebitis development was more common in patients in the 40-64 age group, on the wrist, on the left arm and on the actively used arm, in sites where the PIC was inserted in two or more attempts, in patients in whom 16 Fr or 18 Fr catheters were inserted, and in patients taking antibiotics.

The Hereditary Pyropoikilocytosis is a rare and severe form of Elliptocytosis, characterized by an alteration in the skeleton of the red blood cell membrane. It is an autosomal dominant condition with variable penetration in elliptocytosis, which may be in homozygosity or double heterozygosity in Pyropoikilocytosis, starting from the neonatal period, with clinical manifestations of persistent jaundice. We report here a case of a newborn with persistent jaundice, associated with anemia requiring blood transfusion. The clinical evolution and laboratory findings were conclusive for the diagnosis of Hereditary Pyropoikilocytosis.
Let's Talk About Decolonial Internationalization
Authors: Ozyonum Ezgi
Published: August 2023

There is increasing pressure on higher education institutions (HEIs) to adopt internationalization strategies. The phenomenon of internationalization of higher education is described as “the intentional process of integrating an international, intercultural or global dimension into the purpose, functions and delivery of post-secondary education, in order to enhance the quality of education and research for all students and staff, and to make a meaningful contribution to society” (De Wit et al., 2015, p.281). In higher education, we face a central problem. While universities promote internationalization strategies, they spread Eurocentric ways of knowing, standards, and norms as global. International mobility is predominantly a student and faculty movement from the East to the West. This mobility disseminates the colonial global educational engagement where the West seems to be the ultimate knowledge producer. The challenge of HEIs is to interrupt the colonial patterns in international education. This position paper examines the hierarchy of knowledge production in higher education through a decolonizing framework. Subsequently, it proposes a decolonial internationalization in the case of Canadian Universities.
COULD THE ACUTE STRONGYLOIDES VENEZUELENSIS INFECTION CAUSE NON-REVERSIBLE HOST MORPHOLOGICAL CHANGES?
Authors: Figueiredo Anna Júlia Fernandes , Resende Flávia da Silva , Mati Vitor Luís Tenório , Anjos-Ramos Luana
Published: August 2023

Although research has investigated the host-parasite relationship in Strongyloides venezuelensis infection in the scope of its immunological implications, the morphological consequences of this response for the host organism are yet to be explored. Our objective was to perform an organ morphometric analysis in Wistar rats infected with the intestinal parasite Strongyloides venezuelensis compared with infected rats treated with ivermectin. Twenty-six animals composed three groups: control (non-infected), infected (infected with 2,000 Strongyloides venezuelensis larvae), and infected treated (infected with 2,000 Strongyloides venezuelensis larvae and treated with ivermectin). All rodents were killed 21 days after infection and morphometric analysis of different organs was performed. The results showed significantly higher body and fecal weight in the infected-treated group. The weight of the small intestine increased considerably in the infected group and decreased in the infected-treated group. Pancreas, right kidney, and heart volume increased in the infected group compared with the control group. Despite treatment, the volumes of the stomach, brain, and left kidney increased in both the infected groups compared with the control group indicating the possibility of non-reversible host morphological adaptations. S. venezuelensis infection can augment both, volume and weight of organs – not necessarily related to the Strongyloides expulsion process – even if the acute infection had been in remission. A potential explanation for these host adaptations, including the occurrence of organ plasticity, are briefly discussed. The following steps encompass a histological analysis to verify the occurrence of hypertrophy/hyperplasia and observe if such morphological alterations remain after infection.

Adaptive Estimation of Distribution Algorithms for Low-Thrust Trajectory Optimization
Authors: Shirazi Abolfazl
Published: August 2023

A direct adaptive scheme is presented as an alternative approach for minimum-fuel low-thrust trajectory design in non-coplanar orbit transfers using fitness landscape analysis (FLA). The spacecraft dynamics is modeled with respect to modified equinoctial elements by considering [Formula: see text] orbital perturbations. Taking into account the timings of thrust arcs, the discretization nodes for thrust profile, and the solution of multi-impulse orbit transfer, a constrained continuous optimization problem is formed for low-thrust orbital maneuvers. An adaptive method within the framework of the estimation of distribution algorithms (EDA) is proposed, which aims at conserving the feasibility of the solutions within the search process. Several problem identifiers for low-thrust trajectory optimization are introduced, and the complexity of the solution domain is analyzed by evaluating the landscape feature of the search space via FLA. Two adaptive operators are proposed, which control the search process based on the need for exploration and exploitation of the search domain to achieve optimal transfers. The adaptive operators are implemented in the presented EDA and several perturbed and nonperturbed orbit transfer problems are solved. The results confirm the effectiveness and reliability of the proposed approach in finding optimal low-thrust transfer trajectories.
Experimental Study of an Asymmetric Tandem Wing Configuration for Drone Application
Authors: Traub Lance W.
Published: August 2023

A low-speed wind tunnel investigation characterizing the performance of an asymmetric tandem wing is presented. Wind tunnel data were supported by numerical modeling and flow visualization. The opposing wing halves of a rectangular [Formula: see text] wing were systematically shifted fore and aft along a central fuselage to yield asymmetry. The results show that the lift curve slope, minimum drag coefficient, and Oswald efficiency factor are weakly affected by asymmetry, a result supported by numerical computations. The maximum lift-to-drag ratio, however, dropped essentially linearly with increasing asymmetry, a consequence of the reduced aspect ratio of each wing half decreasing the lift coefficient for minimum drag. Comparison of the experimental results with a symmetric wing with conventional empennage suggests that an asymmetric tandem wing configuration may be a viable geometry for deployable flight vehicles such as tube-launched drones.

Loss of control (LOC) is a prevalent cause of drone crashes. Onboard prevention systems should be designed requiring low computing power, for which data-driven techniques provide a promising solution. This study proposes the use of recurrent neural networks (RNNs) for LOC prediction. Four architectures were trained in order to identify which RNN configuration is most suitable and if this model can predict LOC for changing aerodynamic characteristics, wind conditions, quadcopter types, and LOC events. One-hundred and seventy-two real-world LOC events were conducted using a 53 g Tiny Whoop, a 73 g URUAV UZ85, and a 265 g GEPRC CineGO quadcopter. For these flights, LOC was initiated by demanding an excessive yaw rate (2000 deg/s), which provokes an unrecoverable upset and subsequent crash. All RNNs were trained using only onboard sensor measurements. It was found that the commanded rotor values provided the clearest early warning signals for LOC because these values showed saturation before LOC. Moreover, all four architectures could correctly and reliably predict the impending LOC event 2 s before it actually occurred. Furthermore, to investigate generality of the methodology, the predictors were successfully applied to flight data in which the quadcopter mass, blade diameter, and blade count were varied.
Harnessing Instability Mechanisms in Airfoil Flow for Data-Driven Forecasting of Extreme Events
Authors: Barthel Benedikt , Sapsis Themistoklis P.
Published: August 2023

For certain Reynolds numbers, airfoils are subject to sporadic high-amplitude fluctuations in the aerodynamic forces. These extreme excursions may be seen as prototypical of the kind of unsteady and intermittent dynamics relevant to the flow around airfoils and wings in a variety of real-world applications. Here we investigate the instability mechanisms at the heart of these extreme events, and how they may be harnessed for efficient data-driven forecasting. Through a wavelet and spectral analysis of the pressure and vorticity, we find that the extreme events arise due to the instability of a specific frequency component distinct from the vortex shedding mode. During these events, this extreme event frequency draws energy from the energetically dominant vortex shedding flow and undergoes an abrupt transfer of energy from small to large scales. We propose a preprocessing algorithm to extract this extreme event frequency from the surface pressure data, which in conjunction with an extreme event-tailored loss function, allows us to avoid the commonly used long short-term memory architecture in favor of a simple feed-forward network—a significant reduction in cost over the previous state-of-the-art. Our model requires only three pressure sensors, and it is robust to their location—showing promise for the use of our model in dynamically varying applications. Finally, we show that relying solely on the statistics of the pressure and drag data for optimal sensor placement fails to improve model prediction over uniform or random sensor placement.

This study investigates the discharge and dynamic characteristics of surface dielectric barrier discharge ion-wind thrusters made of polymethyl methacrylate, quartz, and polyvinylidene difluoride on a Martian surface filled with carbon 4 dioxide. Surface dielectric barrier discharge is a typical dissipative nonlinear spatiotemporal dynamical system. Space-charge accumulation and electron backflow are the main causes of gas multipulse asymmetric discharge. The heat generated by high-velocity particle bombardment and polarization loss in the filamentary discharge channel results in the partial breakdown of polymethyl methacrylate and polyvinylidene difluoride, reducing the electrical capacity of both dielectrics. The space-charge and shielding effects of the discharge plasma region are the main internal mechanisms influencing the thrust and thrust-to-power ratio. The maximum surface flow velocities of the three ion-wind thrusters are 22.1, 23.2, and [Formula: see text], respectively. The maximum thrust reaches approximately 84.48, 97.48, and [Formula: see text], respectively.The maximum thrust-to-power ratio is 15.18, 17.03, and [Formula: see text], respectively. The change in the thrust and thrust-to-power ratio spans four orders of magnitude and can be adjusted in a broad range.
Antitrust Accountability Delayed: State Antitrust Enforcement and Multidistrict Litigation
Authors: Alford Roger P.
Published: August 2023

State Attorneys General play a crucial role in the enforcement of antitrust laws. Defendants have successfully delayed state enforcement proceedings by centralizing them with private lawsuits in multidistrict litigation. A new venue law has foreclosed that delay tactic, placing State Attorneys General on equal footing with federal antitrust enforcers in deciding where, when, and how to prosecute antitrust cases.
Hub-and-Spoke Conspiracies: Can Big Data and Pricing Algorithms Form the Rim?
Authors: Weber Bradley C.
Published: August 2023

A hub-and-spoke conspiracy is a metaphor used to describe an antitrust cartel that includes a firm at one level of a supply chain—such as a buyer or supplier—who acts like the “hub” of a wheel. Vertical agreements up or down the supply chain act as the “spokes,” and a horizontal agreement among the spokes acts as the “rim” of the wheel. Courts have considered hub-and-spoke conspiracies for more than eighty years, and there is large body of case law that pertains to the evidence that is necessary for proving this type of antitrust conspiracy.

With the rise of modern digital technologies, firms have increased their reliance on “big data” and data-driven pricing algorithms to determine the prices for their products and services. Using big data, current pricing algorithms can quickly monitor market conditions, including the behavior of rival competitors, and adjust prices in near real-time. Analytical pricing tools that adjust prices based on supply-and-demand conditions and/or costs can create procompetitive benefits because they have the potential to increase efficiency. Anticompetitive effects can occur, however, when multiple competitors use the same pricing algorithm and data set supplied by a common service provider who acts as a hub.

This article will explain the history, structure, and characteristics of hub-and-spoke conspiracies. It also will discuss agreements among competitors to exchange confidential price information, which itself can result in antitrust violations under certain circumstances. Finally, the article will summarize and comment on a new wave of antitrust lawsuits that allege hub-and-spoke conspiracies based on competitors’ mutual use of big data and algorithms to set prices.
TikTok’s Fall From Grace: How Growing Security Concerns in Chinese Technology Affect U.S. Courts and Presidential Successors
Authors: Cartwright Madeline
Published: August 2023

In recent years, the United States government has warned that China may use Chinese companies as a vehicle for infiltrating American data security. The U.S. first acted on this warning in 2017 when it effectively banned Huawei—one of the world’s largest telecom companies—from the U.S. market. Then-president Donald Trump subsequently turned the controversy to the popular social media app, TikTok, in an attempted ban over alleged privacy issues. Personal data collection and the legal implications behind trying to ban China-linked apps is an increasingly controversial topic in American politics. This article assesses the lawsuits following these groundbreaking governmental movements, including how the case of Huawei v. United States compares to the lawsuits and court decisions following Trump’s executive order prohibiting transactions between U.S. citizens and TikTok’s parent company, ByteDance. This includes an analysis of the holdings various courts reached and why they differ among jurisdictions, parties, and claims. Finally, this article will discuss future implications for TikTok and what the U.S. government may need to prove to place the app in the same sphere as its Huawei counterpart.
Data for Sale: Navigating the Role of Data Brokers and Reproductive Health Information in a Post-Dobbs World
Authors: Chong Heather
Published: August 2023

Data privacy is a growing concern in our fast-paced society, as it has become increasingly necessary to relay and retain information digitally. However, the United States trails behind its counterparts in terms of the strength of existing data protection legislation. Unlike the European Union and its General Data Protection Regulation (“GDPR”) law, the United States has no similar comprehensive data protection act. This lack of legislation has led to the exploitation of people’s private data and allowed companies to utilize loopholes in current laws to access sensitive health information. Data brokers have been collecting and reselling consumers’ personal information, including their health data. To combat the actions of data brokers and other parties that might desire to be privy to sensitive data, the bipartisan American Data Privacy and Protection Act (“ADPPA”) has been proposed and is arguably the nation’s first comprehensive legislation affecting information privacy that has a substantial prospect of passage. This case note looks at the history of data brokers and their relationship to the evolving field of data privacy, specifically concerning reproductive health information. Additionally, an overview and comparison of the GDPR is examined. Recent trends in government action concerning the protection of reproductive health information are discussed, and the possible effects of the passage of the ADPPA are considered, too.
