Published: January 2021

El objetivo de este estudio fue determinar la flora palinológica en las localidades de Huarán y Cuyo Grande delValle Sagrado de los Incas y contribuir al conocimiento palinológico en la región Cusco. Se identificaron en total 120 especies fanerogámicas dentro de un área de 1 000 metros de radio alrededor de dichas localidades, durante los meses de enero-abril y julio-octubre de 2013. A partir de las flores obtenidas, se extrajo el polen contenido en ellas para luego realizar preparaciones microscópicas acetolizadas. La observación de los caracteres polínicos se ejecutó sobre 25 granos de polen por especie, tomándose medidas de eje polar (P), plano ecuatorial (E) y algunos elementos esculturales, además se recabaron datos del tipo de polen, ornamentación de la exina y descripción del tamaño del grano de polen; la forma se determinó como la relación P/E. Para los datos cuantitativos se utilizaron los estadísticos descriptivos. Asteraceae, Fabaceae, Lamiaceae, Rosaceae y Solanaceae presentaron mayor número de especies. El tipo de grano de polen más frecuente fue el tricolporado (54.17 %), en cuanto a forma, fue el oblato esferoidal (41.67 %), en patrón de ornamentación de la exina, el más frecuente fue el reticulado (28.33 %) y en cuanto a tamaño, el mediano fue el más recurrente (45.83 %). Estos resultados sugieren que los caracteres analizados tienen importancia taxonómica, permitiendo la clasificación de las especies estudiadas, y que posteriormente pueden ser utilizados en trabajos aplicados sobre palinología.

Sentiment analysis in a sentence describes the part of the consideration of an entity or a event regarding the product, service, topic, issue, person, organization, or event that becomes the target object in sentiment sentences. Judging from several reasons for positive and negative sentiments originating from social media, researchers will use social media not only to communicate between friends, but will be used as a means to find out an aspiration for the community, especially the Indonesian community regarding legal issues or problems related to government. One of the aspirations that will be analyzed is the performance of PSSI. In analyzing this, researchers using the Backpropagation Method are learning methods to reduce error rates by adjusting their weight based on the desired output and target differences. Backpropagation is also a systematic method for multilayer training in Artificial Neural Networks. Backpopagation is said to be a multilayer training method because Backpropagation has three layers in the training process, namely input layer, hidden layer and output layer

Published: January 2021

Non-cash Food Assistance (BPNT) is food social assistance in the form of non-cash. In its implementation, this program still encounters a number of obstacles, one of which is in the sub-optimal distribution of aid in several regions, including Karya Jaya Village. This is because the Ministry of Social Affairs is not optimal in determining BPNT recipients. One way to solve this problem is by utilizing one of the data mining concepts, namely the classification technique with the K-Nearest Neighbor algorithm. Where KPM data previously only accumulated can be used as useful information, one of which is to predict the eligibility of BPNT recipients in the next period. The results of this research are in the form of information on the results of predictions of appropriate KPM as BPNT recipients in 2021 and Local Environmental Units (SLS) which are the most receiving regions. This information can be used as evaluation material for the Ministry of Social Affairs in determining the more targeted BPNT recipients. The prediction results of BPNT recipients in Karya Jaya Village in 2021 are 511 recipients with an accuracy rate of 75.79%, 76.17% Precision, 89.24% Recall, and 82.19% F-measure. And it can be seen that the most BPNT recipient categories are in SLS RW 005, namely 74 recipients. Where there are variables that most influence, namely sta_kis

By using the Heuristic Of Responsive Web Design method as a benchmark to make this e-learning website, hoped that the website design and purpose will be fulfilled the need and expectations of students who want to find lessons material and want to learn by online.
A numerical analysis of compressive residual stresses in cold gas dynamic spray (CGDS) deposition method
Authors: Oyinbo Sunday Temitope , Jen Tien-Chien
Published: January 2021

This study presents a finite element approach of a numerical model to investigate the profile of the deformed sprayed particles and the compressive residual stresses analysis at the interfacial zone of particle and substrate impact using cold gas dynamic spray (CGDS). The Lagrangian approach was used to analyze, in details, the material deformation behavior during impact, contact problems of single-particle impact process and the outputs of equivalent plastic strain and temperature to achieve a qualitative understanding of cold gas dynamic spray contact process of cold sprayed particle on the substrate. The evolution of residual compressive stresses during impact was also analyzed for multiple-particles impact process using the Lagrangian approach. It can be observed that the compressive residual stresses increase by increasing the preheating temperature and particle initial impact velocity.
Effect of non-linear leaflet material properties on aortic valve dynamics - A coupled fluid-structure approach
Authors: Amindari Armin , Kırkköprü Kadir , Saltık İrfan levent , Sünbüloğlu Emin
Published: January 2021

Due to complex structure of aortic valve (AV) leaflets and its strong interaction with the blood flow field, realistic and accurate modeling of the valve deformations comes with many challenges. In this study, we aimed to investigate the effect of AV material properties on the valve deformations, by implementing different non-linear properties of the AV leaflets in three different material models. In the computations, we captured the dynamics between the leaflet deformations and blood flow field variations by using an iterative implicit fluid-structure interaction (FSI) approach. By comparison of the FSI simulation results of these three models, the effects of hyperelasticity and anisotropy on the valve deformations have been studied in detail. The simulation results reveal the fact that the material characteristics strongly affect the deformation characteristics of the leaflets in the systolic phase. The material anisotropy stabilizes the leaflet movements during the systolic phase, which helps decreasing the flutters of the leaflets during the peak jet blood flow. Similarly, it has been observed that the hyperelastic behavior yields an increase in the valve opening area during systolic phase which prevents the risk of excessive work of the heart due to high pressure difference. Furthermore, simulation results indicate that the stress levels in hyperelastic model are much lower, compared to the stress levels in linear elastic one. This suggests that the non-linear material character of the leaflets decreases the risk of calcification.
An analytical and experimental study on dampening material effects on the dynamic behavior of free-free aluminum sheets
Authors: Khorasani R. , Kordkheili S. A. Hosseini , Parviz H.
Published: January 2021

This work aims to present an experimentally verified analytical solution to examine damping properties of systems including viscoelastic treatments. Although there are several methods for characterizing the behavior of three-layer damping systems, the RKU method is the most frequently used one. In this paper, this method is modified such a way that to be applied for a five-layer damping system. The achieved analytical relations are then employed to study the effects of a four-layer vibration-absorbing coating on the dynamic behavior of an aluminum sheet with free-free boundary conditions. Since the vibration-damping properties of the coating are unknowns, its loss factor and shear modulus are experimentally extracted based on the ASTM E756-05 standard method. The comparison between the analytical solution and performed modal tests expresses the efficiency of the presented method.
A delayed differentiation multiproduct model with the outsourcing of common parts, overtime strategy for end products, and quality reassurance
Authors: Chiu Singa Wang , Chiu Victoria , Hwang Ming-Hon , Chiu Yuan-Shyi Peter
Published: January 2021

Production planners today must simultaneously face with the time and quality demands of various goods externally and meet limited capacity internally. This study presents a two-stage delayed- differentiation multiproduct model that considers the outsourcing options for common parts, overtime strategy for end products, and quality reassurance to assist in making fabrication runtime decisions that are cost-effective. Stage one produces all necessary common intermediate components for end products. To reduce stage one’s utilization/uptime, this study adopts a partial outsourcing option. Stage two uses an overtime strategy to fabricate end products that further shorten the uptime. The production processes in both phases are assumed to be imperfect. This study employs the reworking/scrapping of random faulty items to reassure product quality. The researchers build a model to depict the proposed problem’s characteristics and used the mathematical modeling, analysis, and optimization approach to determine the best rotation cycle length that minimizes the system’s expenses. Further, in this study, the researchers provide sensitivity analyses and a numerical illustration, which validate the result’s applicability and exhibit its capability. This result contributes to practical multiproduct-fabrication by (1) deriving the optimal manufacturing policy for a delayed-differentiation multiproduct system with dual uptime reduction policies and quality reassurance; and (2) offering a decisional model that allows production planners to explore the collective/separate effect of a quality-ensured and dual uptime reduction strategy on a problem’s operating policy and crucial system performance indicators, which assists in cost-effective decision-making.

Informal Practices in Public Administrations in Cameroon
Authors: WARAI Michael TAOYANG
Published: January 2021

The article questions the practices of violation of the law and the link between illegality and administrative practices, with a focus on administrative services. In this paper, I propose to study the experience of Cameroon, a country where formality and informality work hand in hand. Precisely, administrative practices have for some time seen the proliferation of unconventional practices in the management of administrative services. The assessment is the use of informality that rub shoulders with the formal rules established by the legislator. The informal management of administrative services can be explained on the one hand by the state crisis which results in the state registry struggling to take. Administrative burdens as an institutional factor should not also be overlooked as an explanatory factor for this practice. Informality, therefore, becomes an alternative to bypass regulatory frameworks. The objective of this article is to stimulate reflection on the role that informality can play in administrative practices in Cameroon. Starting from the principle of methodological individualism, we demonstrate that informality is a vector of underdevelopment, and this way of doing must retain the attention of governments to overcome this practice.
Public-Private Partnership (PPP) as an Alternative Model to Public Infrastructure Development and Service Delivery: The Case of PPP-Public Markets in the Philippines
Authors: ISOLANA JACK B.
Published: January 2021

The study examined the internalization of core-values of New Public Management (NPM) among Local Government Units (LGUs) in the Philippines in their effort to reform the management and operation of public markets.  Using Public-Private Partnership (PPP) as a framework of NPM for infrastructure development and service delivery, the study assessed the performance of PPP/BOT Public Markets in addressing the perennial problems of public markets in the Philippines. It inquired whether or not PPP as an instrument of reform has improved the management and operation of public markets.To substantiate the assessment, five pioneering PPP public markets in the country were examined, namely; Mandaluyong Public Market in Mandaluyong City, Carmen and Cogon Public Markets in Cagayan de Oro City, Suki Market in Quezon City, and Bocaue Public Market in Bocaue, Bulacan. It used organization and management, the scope of facilities and services, LGU-revenue income and expenditures, and income of market vendors, and client satisfaction on the quality of facilities and services as performance indicators. The data of the study were obtained through combined research methodologies such as case study, content analysis, ocular inspection, and interviews with the city and municipal administrators, market administrators, market vendors, and officers of market vendors associations.The study shows that while PPP has improved the performance of public markets during the early years of operation, these gains and all advances were not sustained by the LGUs when management and operation of public markets were turned over to them from the private project proponent-operators. The study argued that in order to sustain public-private partnerships in the operation of the public market, it is imperative to institutionalize reforms in the structure, processes, mindsets of the leaders, and stakeholders. The institutionalization of NPM’s core values can be carried out effectively through localization of PPP as a policy so that the necessary legal and institutional frameworks for PPP will be anchored based on the need, strength, and weaknesses of the LGU concerned.The study makes a positive contribution to the on-going discourse on public sector reform in the Philippines particularly at the local level using PPP as a model. It enriches not only the literature of Public Administration but also provides valuable lessons in the praxis of governance.

The frequency of select adaptation disorders in preterm newborns
Authors: Sochocka Lucyna
Published: January 2021

Background: Preterm birth, defined as the birth of an infant before 37 complete weeks of gestation, is the single
major cause of death and disability in children up to 5 years of age in the developed world.
Aim of the study: The study aimed at analyzing select adaptation disorders in newborns delivered between
34–37 weeks of gestation and in particular, (1) determining the frequency of breathing, thermoregulatory,
hypoglycemic and pathological hepatic disorders, and (2) examining underlying factors that determine their
incidence.
Material and methods: The study was carried out according to the documentoscopy on the basis of medical
files collected between 2019–2020 at the Neonatal and Preterm Baby Unit in WS SPZOZ (the regional hospital)
in Nowa Sól. The records of 102 preterm newborn patients were examined, which included the birth book,
detailed newborn observation charts, fever charts and individual patient observation charts.
Results: The most commonly diagnosed disorders included hepatitis (21.6%; 50) and thermoregulation disorders
(20.3%; 47). Additionally, hypoglycemia and tachypnea were observed in every third child (31.4% and
29.4%, respectively) and almost every fourth newborn experienced some respiratory disorders (23.5%). Among
the findings, maternal and gestational age were not found to be statistically significant with respect to an association
with the incidence of the disorders examined in the study. However, hepatitis was more frequently diagnosed
among naturally born children (64.5%) compared with those delivered by Cesarean (C) section (42.3%,
p=0.039). Respiratory disorders were more often found in children delivered by C-section (21.1%) than in those
born naturally (3.2%, p=0.022).
Conclusions: Hepatitis and thermoregulatory disorders occurred most frequently in preterm infants of all the
adaptation disorders examined. The type of delivery was quite determinant for some of the disorders. Hepatitis
was found more often in naturally born babies than in those delivered by C-section, whereas respiratory
problems occurred more frequently in children delivered by C-section compared with those delivered naturally.
Mothers who wish to deliver their babies by C-section should be informed about potential complications associated
with the occurrence of respiratory disorders. They can stem from the absorption of pulmonary liquid
and inappropriate surfactant activity, which can lead to some serious abnormalities related to the improper
exchange of respiratory gases.
Interpersonal relations in social research. Selected search prospects
Authors: Czykwin Elżbieta
Published: January 2021

Especially for laymen, interpersonal relationships seem to be clumsy and chaotic. Due to the dynamics, uniqueness, emotionality and embedding of interpersonal relations in various situational contexts, they elude the scientific objective perspective of the approach.
However, social sciences have generated a number of approaches that allow researchers to see it in a more coherent and research-operational way. Some of them are mentioned in the article.
The semantic-linguistic approach is fertile and promising. I evoke them by citing two metaphors: organic and dramatic by Erving Goffman. I also pay attention to the individual and social nature of the conceptual category of the reflected self (Charles Cooley), which reveals the individual-social nature of this concept. Yet another is the much explaining the labeling approach of Howard Becker, the role of expectations (Robert Rosenthal) and the significant current of ethno-methodology.
In addition to these well-known perspectives, new ones have emerged in recent years. These include the stigmatizing approach introduced by Goffman in the 1970s, but which has found new theoretical and research continuations today. Reaching for emotions is something completely new, especially in sociology. I am referring here to the importance of the emotion of shame as the most fundamental emotion in the terms of Thomas Scheff.
Digital technology in the context of social science teaching at secondary schools
Authors: Vališová Alena
Published: January 2021

The goal of the study is to contribute to the problem in hand regarding the insufficiently developed digital competencies of teachers of social scientific subjects within the secondary education. The solution to it is based on a precondition that if the teachers will not be digitally competent they will not be able to develop the digital competence of students. This fact can negatively affect their ability to find employment at the labour market of the 21st century, preparedness to further professional education and ability to participate at the lifelong learning. The text at issue solves the problem of digital technology integration into teaching of social sciences, emphasizes multidisciplinary approach to the humanities, social and technological sciences, presents the need of development of teachers´ technical thinking relating to social scientific subjects and specifies common features and differences of the pedagogical and technological sciences. The study is the actual output of the project TAČR (PID: TL 01000192, in the period 02/2018 – 02/2021). It is based on the sub-chapter ”Integration of the digital technology into teaching of social sciences” that will be embodied in the currently prepared monograph “Development of teachers´ digital competencies relating to social scientific subjects at vocational schools”.

CIVIC EDUCATION AS AN IMPORTANT AREA OF EDUCATION FOR PEACE
Authors: Piejka Agnieszka
Published: January 2021

The reflections undertaken in this article focus on the role that civic education plays in education for peace. Certainly these two areas of educational activity are not the same; Education for Peace is a much broader and more complex process, requiring the involvement of all teachers. However, the knowledge, competences and motivations that should be developed as preparation for responsible civic participation are very important for building a peaceful order. I begin my reflections with a brief discussion of the most important issues related to contemporary perception of peace. Next, I refer to the terms "citizen", "citizenship", to highlight their meaning and in this context to reflect on the most important areas of civic education. This is the starting point for showing the tasks included in civic education as essential in the process of building peaceful coexistence of people. These tasks concern different areas of civic education: cognitive, competence, affective, and value areas.In carrying out these tasks we can hope to educate people who contribute to peace building through responsible civic activity.
The Montessori's pedagogy in holistic terms
Authors: Glier Joachim
Published: January 2021

There are already a lot of publications on Montessori’s pedagogy, both abroad and in Poland. The authors of those scientific articles and monographs usually focused on one or more selected issues and discussed them or developed in context of their own research. The great number of those publications isn’t something negative, because it enables getting to know this pedagogical conception in depth. However this great number of studies and the variety of raised issues cause that the constitutive elements of this pedagogy blur in details of this numerous publications and also cause that the originality of this pedagogy becomes difficult to catch. This situation was the reason for attempting to define this pedagogy, that is, to define its constitutive components, to subject them to analyses and then to combine them into a holistic conception of pedagogy called Montessori’s pedagogy.
Requiem for junior high school. Case study - lower secondary school exam 2012
Authors: Piotrowski Marek
Published: January 2021

The article has critically assessed the information sent to the public, including teachers, on the results of external examinations contained in the Central Examination Board (CEB) reports. Basing on the analysis of two sources of information decoded from the CEB reports and the analysis of the database containing the results of examinations, 93% of lower secondary school students, it has been showed that about half of the population "failed" the lower secondary school exam in science and mathematics. Therefore they should not continue their high school education. The analysis of data decoded from the CEB report is in line with the results obtained from 93% of students. Therefore, it is advisable to conduct similar analyzes of contemporary CEB reports on students achievement after the new primary school which is operating in the new education system after liquidation of junior high schools.
Teacher's emotional labor: conceptualization of the idea and research approaches
Authors: Góralska Renata
Published: January 2021

The article describes the notion of teacher’s emotional labor, which is an important and often neglected subject in didactics and pedeutology. The thesis is that the manner in which a teacher's emotional labor is being conceptualized affects test method and interpretation. The article presents three different manners in which emotional labor may be conceptualized: (1) emotional labor as process of emotion regulation (psychological approach); (2) emotional labor as a work requirement (sociological approach); (3) emotional labor as a transformation and development tool/as a byproductive labor (critical approach). Each approach is assigned to a different methodological perspective which may be used by educational researchers: (1) quantitative research; (2) qualitative research; (3) “new'' qualitative studies.

Isolation and Characterization of Exosomes Derived From Breast Cancer MDA-MB-231 Cell Line
Authors: Rafighdoust Zahra , Baharara Javad , Forghanifard Mohammad Mahdi , Kerachian Mohammad Amin
Published: January 2021

Background: Exosomes are membrane nanovesicles, 30 to 100 nm in diameter, secreted by most cell types. Besides playing many biological roles, especially in cell-cell communication, scientific proof indicated that the pathology of so many human cancers is closely related to many biologic elements in exosomes. They may serve as useful biomarkers for treatment, prognosis, and detection. Cancer cells produce more exosomes, inducing changes in target cells (near or distant from the tumor), such as metastasis and chemotherapy resistance. Therefore, isolation, identification, and analysis of these microvesicles seem essential. Objectives: The current study aimed at collecting and purifying microvesicles secreted from breast cancer cells and confirming the identity of the obtained exosomes using methods assessing size and morphology. Methods: In recent research, the MDA-MB-231 cell line was grown under standard conditions. Released exosomes were collected and ultra-centrifuged. Scanning (SEM) and transmission (TEM) electron microscopes, atomic force microscopy (AFM), and dynamic light scattering (DLS) were used to assess exosome size. Results: The obtained data revealed that MDA-MB-231 cells produced exosomes. The nanovesicles were isolated from the culture medium of MDA-MB-231 cells by applying different strategies, including differential centrifugation, filtration, and ultracentrifugation. The exosomes were characterized; they had a size of 30 - 100 nm and spherical shape. Conclusions: Intercellular communication can be mediated through direct cell-cell contact or transfer of secreted molecules. In the last two decades, a third mechanism for intercellular communication has emerged that involves intercellular transfer of extracellular vesicles (exosomes). Due to their many functions in the body, it is of great importance to purely isolate and recognize exosomes to understand their modes of action as the first step in the advancement of researches. However, more research is required to obtain cost-effective and efficient methods. It was found that MDA-MB-231 cells release exosomes. They are spherical and 30-100 nm in diameter. The use of a combination strategy for the first time was useful in isolating exosomes derived from MDA-MB-231 cells without disturbing their structure. Further studies are required to compile a uniform protocol for exosome isolation in medical research.

Background: The impact of COVID-19 on mental health outcomes of medical residency is an important concern. Currently, evidence regarding this issue is not sufficient. Objectives: The current study aimed to demonstrate the impact of the COVID-19 pandemic on residency training programs as well as its psychological consequences for both individuals and their families in the Kurdistan Region, Iraq. Methods: This online cross-sectional study was performed at the Kurdistan Region, Iraq, from 12 - 25 August 2020. In total, 275 residents participated. Data were collected online, and the items were sent through specific Facebook and Viber groups of residents. Data were analyzed using descriptive statistics (i.e., frequency and percentage). Besides, the Chi-square and Fisher's exact test were used to compare the participants based on their sociodemographic characteristics. Results: Of 275 participants, 50.9% were female and mostly older than 30 years (52.4%). Surgical (36.4%) was the most commonly cited specialty, followed by medical (22.2%). Around 40% of residents were forced to changes the hospital due to the COVID-19 pandemic. Also, 50% of them had close contact with COVID-19 patients, and only 12.7% had enough training for the proper use of personal protective equipment (PPE). Moreover, 90% of the residents felt anxious and concerned about the situation. Nearly 10% of residents were infected with COVID-19, and 24% of them had an infected family member. Approximately 92% reported a reduction in training activities due to the COVID-19 outbreak. Of those with surgical specialties, 83% reported a significant reduction in the number of surgeries since the onset of the pandemic (P < 0.024). Conclusions: The COVID-19 pandemic has caused high levels of psychological distress of medical residency. The combination of psychological disorders with high infection rates among students of residency in our region may cause a critical impact on the residency training program. Besides, the quality of programs may also be influenced. An urgent plan is required to reduce the psychological stress and protecting doctors against the infection.

Context: Multisystem inflammatory syndrome in children (MIS-C) is an emerging condition after the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, termed COVID-19. This study aimed to describe the cardiac manifestations of children diagnosed with MIS-C. Evidence Acquisition: This narrative review was conducted by searching the PubMed, Scopus, and Google Scholar databases to review MIS-C cardiac manifestations up to September 30, 2020. The demographic features, past medical history, clinical signs and symptoms, cardiac involvement, and the type of COVID-19 diagnosis confirmation were extracted. Results: In many children, MIS-C seems to be a post-infectious complication of the COVID-19 infection. This syndrome affects multiple organs and has various clinical manifestations mimicking Kawasaki disease. Patients frequently present with persistent fever, kidney injury, gastrointestinal (GI) problems, neurologic symptoms, mucosal changes, conjunctivitis, and cardiac involvement. Children with MIS are more likely to present with hypotension, shock, and cardiac dysfunction, rather than coronary artery abnormalities and arrhythmia. Children with MIS need close observation; some need to be hospitalized, and a few may need a Pediatric Intensive Care Unit (PICU) admission. Treatment currently includes anticoagulants, IV immunoglobulin, and anti-inflammatory drugs. Conclusions: As a novel syndrome associated with SARS-CoV-2 infection, MIS-C is potentially lethal. Cardiac manifestations, including coronary and myocardial involvement, are common and should be carefully identified. With prompt diagnosis and proper treatment, most children will survive, but the outcomes of the disease are unknown, so long-term follow-ups are required.

Published: January 2021

Background: Sleep deprivation is a common problem among the elderly in the cardiac care unit (CCU). Objectives: The present study aimed to determine the effects of environmental modifications on sleep quality improvement in these people. Methods: The study population included 60 elderly patients whose sleep quality was assessed by the Pittsburgh Sleep Quality Index with even domains. The environmental factors that can disturb sleep quality were determined via a questionnaire, including 13 questions on a 5-point Likert scale. Descriptive and inferential statistical analyses were performed in SPSS 22 software via independent sample student t-test and chi-square. Results: After environmental modifications, the total sleep quality scores changed from 11.8 to 5.96, indicating sleep quality improvement. Before executing the environmental modifications, there were no significant correlations between sleep quality scores and demographic variables (sex, age, marital status, and economic status). However, after the modifications, there was a significant relationship between sleep quality and economic status (P = 0.024). Conclusions: Environmental factors can affect sleep quality in the elderly hospitalized in CCU. Therefore, it is possible to improve sleep quality in these individuals by modulating environmental conditions.
Произведение сайнс-арта как пограничный объект в зонах обмена

В статье рассматривается и уточняется понятие пограничного объекта на примере произведений сайнсарта. Утверждается, что специфика аутентичного произведения искусства состоит в его негативности, которая проявляется в способности к критической рефлексии и преодолению собственных границ. Сайнсарт репрезентирует негативную эстетику благодаря выходу за пределы искусства и обращению к инструментарию и проблематике науки. Негативность сайнсарта лежит в основе его интерпретативной гибкости, характерной также для пограничных объектов, которые функционируют на пересечении различных культурных и социальных миров. Представители этих миров способны поразному трактовать пограничный объект, исходя из собственных целей и ценностных установок. В статье делается вывод о том, что проекты в области сайнсарта способствуют превращению лабораторий, художественных галерей и других пространств, связанных с искусством и наукой, в зоны обмена, результат деятельности которых воплощается в пограничном объекте – произведении искусства. Взаимодействуя с профессиональными исследователями, художники получают доступ к новым средствам выразительности и репрезентации своих идей. С другой стороны, ученые, следуя за творческой интуицией художников, неожиданно сталкиваются с новыми вопросами и исследовательскими горизонтами. Именно о такой специфике взаимодействия ученых и художников свидетельствуют проекты С. Ли и М. де Менезиш, приведенные в статье в качестве репрезентативных примеров сайнсарта. По итогам проведенного анализа делается вывод о том, что функционирование зон обмена невозможно без сохранения акторами собственной идентичности и системы ценностных координат, что, однако, не мешает их плодотворному сотрудничеству.
