Neurogastronomy: Factors Affecting the Taste Perception of Food
Authors: Tokat Pelin , Yılmaz İlkay
Published: November 2022

Neurogastronomy is a new formation that includes many researches to provide a connection between gastronomy and neurology. The existence of biological, emotional and cultural factors as flavor in the brain can be explained as neurogastronomy. The data received with the five senses are collected in the brain and perceived in its relevant parts. Research on what kind of perception is created with the formation of missing sensory data in the brain has been increasing day by day. In addition, by considering the different reflections of sensory data from reality, it is examined how they lead to perceptions in the brain. Plate design is very important in terms of visual presentation. What kind of an effect the presentation types of plate design have on customers and what kind of plate design they prefer is a matter of curiosity for researchers. Every stage of life continues in the light of technological developments. One of these technological developments is virtual reality. With the use of virtual reality in the field of neurogastronomy, it is possible to simulate the senses differently. This situation creates the possibility of causing different perceptions in the brain. In this study, neurogastronomy, the concepts of taste and flavor and the parameters affecting the perception of taste were addressed, the studies on the effect of plate presentation and atmosphere were examined, and information was conveyed by making a comprehensive literature review.

Conflicts Of Interest over the Libyan Crisis and Its Impact on the National Security of Armenia
Authors:   Center for Culture and Civilization Studies, Kyureghyan Shushan
Published: November 2022

The Arab Spring, a chain of anti-government protests and uprisings, had major implications throughout the Middle East region and it particularly affected oil-rich countries, including Libya. Libya is the largest holder of proven oil reserves in Africa (48 billion barrels). Before 2011, Libya’s oil production averaged about 1.64 million barrels per day, about 96% of the government’s revenue, which accounted for 60-65% of the country’s GDP. During the reign of Muammar Gaddafi, Libya’s oil industry was run by the state-owned National Oil Corporation (NOC), which was responsible for implementing Exploration and Production Sharing Agreements (EPSA) with international oil companies (IOCs). Among these international oil companies were ENI (Italy), Total (France), Repsol (Spain), OMV (Austria) and Equinor (Norway). Colonel Muammar Qaddafi was not considered to be a reliable partner for the above-mentioned international oil companies. He used to demand tough contract terms, frequently raised fees and taxes and made other restrictions. This policy was in stark contrast with the interests of foreign actors, especially a number of Mediterranean European states, which led to their active participation in Libyan politics with the desire to gain a greater share of oil production and increase their influence in Africa. The main struggle over Libya is for control over oil resources which are highly necessary for a number of external actors in order to ensure the dynamic development of their economies and strengthen their geopolitical position but which are also needed by regional actors to ensure their own security. From the point of view of global governance, each actor in this conflict is trying to implement its global agenda by having political control and a military presence in Libya. The main aim of this study is to analyze the conflict of interests between local, regional and international actors over the Libyan issue, which, undoubtedly, affects the policy of these forces towards our region, and to understand how these developments in a country “far from” Armenia can influence the Republic of Armenia’s national security and foreign policies.

U.S. Foreign Policy under President Trump: The Middle East, Eastern Mediterranean and Black Sea Regions
Authors:   Center for Political and Economic Strategic Studies, Poghosyan Benyamin
Published: November 2022

The current phase in international relations can be best characterized by one word – transition. The Post-Cold War order is rapidly disappearing, creating strategic ambiguity for all actors. The U.S. hegemony is over or close to over despite the fact that militarily Washington will be safely far out of reach for several decades to come. However, the growing national debt, the looming crisis in the Social Security and Medicare systems, uncontrolled migration, growing populism and partisan fighting does not bode well for the future of U.S. dominance. At the same time, no nation, be it China, Russia, India or Brazil, has the necessary resources or will to compete for the new world hegemony. The absence of a world hegemon means that no state has the power to enforce the implementation of key international rules and norms. Regardless how one perceives the international principles – as balanced or biased – the rule-based order at least provides a minimal level of stability since the actors involved on the international stage have a clear understanding what may and may not be done. However, since the late 2000s the situation has changed. We are increasingly facing an international security architecture where key actors may easily break the norms and rules, and this will eventually bring us to a situation upon which no rules can be based. The election of President Trump sent shock waves through the United States’ political establishment and surprised international relations pundits worldwide. Despite the apparent growth of the right-wing populist movements in different parts of the world, the culmination of which was presumably the BREXIT referendum held in June 2016, few if any could imagine that a real estate developer and reality TV star had any chance of defeating one of the most respected representatives of the US political establishment. The November 2016 elections had widespread implications on both American domestic and foreign policies. President Trump’s decision to denounce globalism created a situation where the so-called “vertical globalism” (Western-led efforts to spread a liberal international order all over the world through the promotion of democracy and a market economy) might be transformed into a “horizontal globalism” based on regional integration models covering vast territories of Europe and Asia, Africa and Latin America. In this paper we will analyze President Trump’s foreign policy in several key geographical areas and its implications. However, in order to better understand the significant changes in U.S. foreign policy ushered in by President Trump and make predictions for future developments, it is worth starting with an examination of Trump’s foreign policy perceptions as well as of the ongoing debates within the foreign policy establishment itself.
RAID: Tool Support for Refactoring-Aware Code Reviews
Authors: Brito Rodrigo , Valente Marco Tulio
Published: November 2022

Code review is a key development practice that contributes to improve software quality and to foster knowledge sharing among developers. However, code review usually takes time and demands detailed and time-consuming analysis of textual diffs. Particularly, detecting refactorings during code reviews is not a trivial task, since they are not explicitly represented in diffs. For example, a Move Function refactoring is represented by deleted (-) and added lines (+) of code which can be located in different and distant source code files. To tackle this problem, we introduce RAID, a refactoring-aware and intelligent diff tool. Besides proposing an architecture for RAID, we implemented a Chrome browser plug-in that supports our solution. Then, we conducted a field experiment with eight professional developers who used RAID for three months. We concluded that RAID can reduce the cognitive effort required for detecting and reviewing refactorings in textual diff. Besides documenting refactorings in diffs, RAID reduces the number of lines required for reviewing such operations. For example, the median number of lines to be reviewed decreases from 14.5 to 2 lines in the case of move refactorings and from 113 to 55 lines in the case of extractions.
Perception of Software Bots on Pull Requests on Social Coding Environments
Authors: Wessel Mairieli , Steinmacher Igor , Gerosa Marco A.
Published: November 2022

Software bots connect users and tools, streamlining the pull request review process in social coding platforms. Nevertheless, the presence of bots can be annoying and disruptive to the community. Interviewing open-source developers, we created a theory of how human developers perceive annoying bot behaviors as noise. To identify strategies to overcome such problems, we applied Design Fiction as a participatory method with practitioners. Our findings may help practitioners understand the effects of adopting a bot, and researchers and tool designers may leverage our results to better support human-bot interaction on social coding platforms.

Authors: Pereira Ivonildo , Mendes João , Viana Davi , Rivero Luis , Ferreira Waldemar , Soares Sergio
Published: November 2022

Society has become more dependent on technology, so investments in information security have become essential. In Brazil, the General Data Protection Law (Lei Geral de Protecão dos Dados LGPD) legislates information security management. This work aims to propose an instrument to evaluate the adequacy of IoT solutions regarding the LGPD. The proposal evaluation took place in a private institution linked to industrial innovation. The proposed mechanism can assist professionals in verifying the LGPD adequacy in IoT projects. The study identified LGPD compliance defects in an IoT solution deployed in several industries all over the 23 Brazilian states. However, the results cannot be generalized since we only evaluated it in a single company and one software solution. Replications are needed to identify whether these results apply to other companies and solutions.

Authors: Gomes Alan Nascimento , Coutinho Emanuel Ferreira
Published: November 2022

Com a crescente utilização de sistemas computacionais em diversos setores da sociedade, novas tecnologias surgiram, e com elas vários desafios. Blockchain é uma rede ponto a ponto que armazena uma cadeia de blocos, comparável a um livro público, onde cada parte interessada possui uma cópia idêntica, transparente e imutável. Os contratos inteligentes possibilitam na blockchain acordos dinâmicos e com maior confiança na troca de ativos digitais. Porém, apesar da utilização de contratos inteligentes trazer benefícios, há a necessidade de cuidados em relação a ameaças, como vulnerabilidades e erros na lógica de negócio. O objetivo desta pesquisa é discutir sobre a importância de simular contratos inteligentes em blockchain. Para isso, algumas questões de pesquisa foram projetadas, dados foram obtidos de uma revisão da literatura e algumas categorias de aspectos relacionados à simulação de blockchain foram identificados.

Authors: Freitas Isabella Melo , Graciano Neto Valdemar Vicente , Paiva Sofia L. Costa
Published: November 2022

A Interface com Usuário (IU) é um dos componentes mais complexos dos Sistemas de Informação (SI) modernos, já que é necessário alcançar uma comunicação satisfatória entre a IU e outras partes do código, além de oferecer consistência e desempenho aceitáveis [Bowen et al. 2020]. Abordagens de desenvolvimento baseado em modelos tem auxiliado na produtividade e padronização de IU. Este artigo propõe um Metamodelo de Apresentação para IU em Android possibilitando a produção de IU baseada em modelos. A partir de um estudo exploratório com SI para dispositivos Android, foi identificada a falta de padronização devido à política de publicação nessa plataforma. Um Metamodelo de Apresentação e um Estereótipo de IU foram desenvolvidos para a plataforma Android trazendo diretrizes e padrões da plataforma iOS, uma vez que tal plataforma possui diretrizes mais sólidas. Uma implementação do Estereótipo de IU para Android foi feita mostrando a viabilidade de utilizar o Metamodelo como um modelo executável. Os benefícios do Estereótipo de IU para Android incluem não apenas a construção e padronização, mas também a reutilização de SI para a plataforma Android.

Uma Avaliação da Expressividade de Paralelismo da Linguagem Actus
Authors: Favre L. E. , Amorim C. L. de
Published: November 2022

A linguagem de programação Actus foi projetada originalmente para se programar máquinas vetoriais (vector and array processors) oferecendo um modelo de programação paralela síncrona com espaço de endereçamento global. Neste trabalho a expressividade de paralelismo da linguagem Actus é avaliada utilizando 100 loops construídos especialmente para testar a eficiência de vetorizadores comerciais. Os resultados revelam que Actus é insuficiente para expressar o paralelismo de todos os loops. Uma simples extensão da linguagem é proposta, tornando possível expressar o paralelismo de 99% dos loops. Esse resultado é contrastado com os 72% conseguidos automaticamente pelos melhores vetorizadores comerciais.

Learning Parallel Computing Concepts via a Turing Machine Simulator
Authors: Py Mônica Xavier , Toscani Laira Vieira , Lamb Luís C. , Diverio Tiarajú Asmuz
Published: November 2022

lt is well-known that technology developments in Computing Science has led to new developments in Computing Theory and vice-versa. This work is a contribution towards the formalisation of Parallel Processing concepts. We exploit variations of the Turing Machine model, referred as natural extensions, which may be composed by several control units, tapes and heads in such a way that one can define a variety of Parallel Turing Machine models. Several notions and definitions of parallelism are identified including computability, complexity and performance of computations. A prototype of the Parallel Turing Machine model is presented. This prototype was used as a test bed for the assessment of the usefulness of these machine models as a parallel processing teaching tool, as well as a tool to facilitate the creation of a "culture" among students in high performance computing. Finally, we analyse the notions of performance, speedup, efficiency, load balancing, synchronisation and communication in parallel processing.

The selection mechanism helps users choosing the processes they want to control and visualize.
Graffitiprävention durch Eigentümerförderung
Authors: Christoph Stephan , Fleischmann Lena , Folly Anna-Sophia
Published: November 2022

Although Graffiti prevention is typically sprayer-centered, some municipalities are implementing a victim-centered approach as well. Instead of providing “legal spray areas,” a victim-centered approach offers financial support to homeowners who choose to remove illegal graffiti, thus encouraging them to clean affected areas. The study presents both a theoretical and empirical analysis of the victim-centered approach as it operates with the project “Schmierflink” in the city of Augsburg. After evaluating interviews of a multitude of actors in the graffiti “world”, including people from the illegal scene, this study concludes that shifting the focus toward victims makes sense. Nonetheless, it is likely still necessary to embed this victim-centered approach in a comprehensive prevention paradigm.

Toward a Non-Anthropocentric Italian Cinema
Authors: Di Bianco Laura ,   Society for the Philosophic Study of the Contemporary Visual Arts
Published: November 2022

The 2015 film Lost and Beautiful, directed by Pietro Marcello, en­deavors in aesthetically compelling ways to decenter the human in the frame and engage viewers in what Gilles Deleuze and Felix Guattari term becoming animals. Part documentary film, part fairytale, this film tells the story in the nonhuman first person, of the life and journey of a water buffalo calf in the south of Italy and his relationship with the shepherd who saved him from pre­mature death, and later, with Pulcinella, a mythological figure from Neapol­itan folklore, who accompanies him in a journey north. Adopting ecocritical and posthuman perspective and providing elements of environmental cultural history, this article analyses the aesthetic and narrative strategies the film em­ploys to grant subjectivity to a nonhuman protagonist and, in turn, address the viewers. Advocating for the conservation of human artifacts while also posing the question of animal rights and agency, Lost and Beautiful powerfully gestures toward a non-anthropocentric cinema.
Double Reversals in Jim Jarmusch’s Night on Earth
Authors: Forest Michael ,   Society for the Philosophic Study of the Contemporary Visual Arts
Published: November 2022

This essay explores the underlying connections, through reversals and doubling, in Jim Jarmusch’s Night on Earth. The film utilizes more than just similar cinematic techniques across its five episodes, it embeds conceptual connections that result in a strong location-expression conveying to the viewer the unique ‘flavor’ of each of the five cities. The essay explores the concepts of reversal, doubling, location-expression, and spectatorship. It elucidates the filmic expressions of place by gesturing toward expression theory and rasa theory. Ultimately, the film’s unity, like that of a rock band’s LP, holds together enough to suggest the peculiar awareness of the filmgoer’s tourist spectatorship.

Functional thyroid disorders in the pharmacy setting: How can we help our patients?
Authors: Pecikoza Uroš
Published: November 2022

Functional thyroid disorders (hypothyroidism and hyperthyroidism) are amongst the most common endocrine disorders pharmacists encounter on a daily basis. They are highly prevalent in iodine-replete areas, and affect women about 10 times more often than man. Hypothyroidism (thyroid hormone deficiency) is usually caused by Hashimoto's thyroiditis, an autoimmune disorder that leads to gradual thyroid destruction. The drug-of-choice for treating hypothyroidism is levothyroxine, a synthetic form of thyroxine. Key points which need to be discussed with patients who are prescribed levothyroxine for the first time are when/how to administer this drug, how its effects are monitored, what drugs may affect its efficacy, and the importance of properly treating hypothyroidism during pregnancy. Hyperthyroidism (increased production of thyroid hormones) is most often caused by Graves' disease, another thyroid autoimmune disorder in which stimulatory autoantibodies against the TSH receptor lead to increased thyroid function. Graves' disease is most commonly treated with thionamide drugs (thiamazole, carbimazole or propylthiouracil) and patients using these drugs should be advised on the monitoring requirements, duration of treatment, and how to recognize possible serious adverse effects (agranulocytosis and hepatotoxicity), and informed that these drugs must be used during pregnancy in order to reduce the risk of adverse outcomes for the mother and baby.
Thyroid function disorders

Thyroid function disorders are the most common endocrine disorders in humans. They are frequently diagnosed, with prevalence varying between 2 and 6%, and a female to male ratio of up to 10:1. Disorders of thyroid function in the narrower sense are presented by its hyperactivity or underactivity, although there are conditions that lead to an increased concentration of thyroid hormones, without its increased activity. In iodine-sufficient regions, the most common cause of hyperthyroidism, as well as hypothyroidism, is an autoimmune disease of the thyroid. For hyperthyroidism, it is Graves' disease, with typical symptoms and signs of hypermetabolism. The diagnosis of hyperthyroidism is based on suppressed TSH and elevated fT4 (free, and in the differential diagnosis, elevated TSH-receptor-antibodies are crucial for Graves' disease. Management of Graves' disease relies on three equally potent approaches: medical therapy, ablative treatments with 131I-radiotherapy-RAI, and thyroidectomy. Hashimoto's thyroiditis is the most common cause of hypothyroidism in iodine-sufficient regions. Symptoms and signs of hypothyroidism are non-specific and correspond to the symptoms and signs of hypometabolism. The diagnosis is made based on elevated TSH with decreased fT4. Thyroxine-peroxidaseantibodies and thyroglobuline-antibodies are important in differential diagnosis. Sometimes elevated TRAb is found in Hashimoto's thyroiditis. The treatment of hypothyroidism is levothyroxine replacement therapy.

Mercury (Hg) is one of the most important environmental pollutants with endocrinedisrupting properties. There is little data from epidemiological studies describing the doseresponse relationship between toxic metal levels and hormone levels. The aim of this study was to use the nearest neighbor matching analysis to determine the difference in Hg concentration in healthy/sick subjects with thyroid disease and to use Benchmark modeling to determine the doseresponse relationship between Hg levels in the blood and thyroid-stimulating hormone (TSH) and thyroid hormones in serum. Blood samples were collected and used for Hg measurement using the ICP-MS method, and separated serum was used for hormone analysis. The study showed the existence of a statistically significant difference in Hg levels measured in healthy and sick subjects and the existence of a dose-response relationship between Hg and all measured hormones, with a narrow interval obtained for the Hg-TSH pair. The results of this research support the use of the Benchmark dose approach for the purpose of analyzing data from human studies, and our further research will be focused on examining the impact of low doses on animal models in order to determine more precise effects of low doses on the organism.
The Structure of a Three Dimensional Tip Vortex at High Reynolds Numbers
Authors: Stinebring O. , Farrell K. , Billet M.
Published: November 2022

The tip vortex structure of a three dimensional hydrofoil at high Reynolds number was measured experimentally in both the 48-in (1.22- m) diameter water tunnel and the 48-in (1.22-m) wind tunnel at the Applied Research Laboratory, Penn State. The flow on and near the hydrofoil was measured using a number of flow visualization techniques, laser velocimetry (tip boundary layers) and pressure taps. The downstream tip vortex was measured with a three-component laser velocimeter at a number of streamwise positions with a detailed planar mapping of the flow in the region of cavitation inception. The effect of Reynolds number and applied tip roughness on the downstream tip vortex was investigated. In addition, the importance of the unsteady pressure fluctuations in the core on cavitation inception is discussed.
Simulation of Ship Wakes in Water Tunnel Cavitation Testing of Models
Authors: Wilson Michael
Published: November 2022

Reliable cavitation testing of ship propulsors requires accurate modelling of the ship wake velocity field. This paper presents a progress report on efforts at the David Taylor Research Center (DTRC) to generate properly shaped velocity patterns in a water tunnel by means of partial length afterbody models. A survey of references is presented on the general topic of applications and techniques of wake simulation in water tunnels using a variety of means, including screens mounted normal to the tunnel stream; partial length (dummy model) hull representations; and full length geometrically scaled hull models. Three recent examples are described in some detail of successful wake-generating bodies designed for experiments conducted in the DTRC 36-inch Variable Pressure Water Tunnel. The wakes of these examples are taken in order of increasing degree of difficulty. In each case, there is a discussion of the target wake, the body design considerations, and the quality of the resultant simulated wake.

In 1985, the United States Coast Guard and The University of Michigan initiated a planing hull research project. The research was performed as part of the UWUSCG Officer Trainingship Program. Early work at U of M included the design and fabrication of a dynamometer which could oscillate a model venically and measure the resulting forces. Tests were performed for verification of dynamometer performance and to determine added mass and damping coefficients for a prismatic planing form. A description of the dynamometer construction and calibration, and preliminary results are included.
Model Test Techniques to Quantify the Hydrodynamic Added Mass and Damping Associated with Longitudinal Flexural Response
Authors: Menon B. , Howard J.
Published: November 2022

Dynamic loading problems such as springing, propeller-induced vibration or continuous breaking of level ice cover, all involve hydrodynamic phenomena associated with hull responses and fluid reactions. The usual convention, which dates back to Lewis (1929), is to express the coupling between the fluid forces and hull responses in terms of the hydrodynamic added mass and damping effects. These effects are usually quantified by the so called coefficients which are expressed as functions of hull geometry, fluid density, frequency of oscillation and modal response shape. In principle, all modes of vibration participate in the response of a ship's hull to excitation. However, it is generally observed that response to shock or impact loading is dominated by the first few lower modes, while response to cyclic disturbances such as rotating machinery and wave induced loads, is influenced by higher modes with frequencies which couple with the frequencies of excitation. The contents of this paper deals with a special series of preliminary tests carried out to investigate the feasibility of using a segmented flexible model for determining the hydrodynamic added mass and damping.
