Published: December 2021

В статье рассматривается один из многогранных и противоречивых феноменов Я. Арафата – миротворчество. Одновременно в работе называются причины, обусловившие переход лидера палестинского народа к миротворческой политике. Миротворчество рассматривается как скрытая форма, предполагающая неизбежное фронтирное изменение жизненного пространства между Палестиной и Израилем. Подчеркивается, что историческая травма палестинского народа связана с негативным опытом построения государственности. Утверждается, что манипуляция международным общественным мнением (непросвещенными слушателями) в пользу палестинских арабов, шантаж образом непостижимого страдания и, как следствие, возможным негативным сценарием конфликта, содействовали искажению реальности и транспарентности палестино-израильских отношений.

В статье изложены результаты исследований по проектированию операционного цикла конверсии производственного капитала в денежный капитал в условиях литейно-механического завода, обеспечивающего востребованный рынком рост объема реализации продукции. Операционный цикл конверсии разделен на базовый, где произведенная продукция реализуется на основе маркетинговых технологий, и инновационный цикл, обеспечивающий рост добавленной рыночной стоимости. В качестве инструмента, обеспечивающего мотивацию менеджеров и производственного персонала к непрерывной инновационной деятельности, в технологические затраты базового операционного цикла конверсии включена минимальная (согласно законодательства РФ) оплата труда, а все остальные источники формирования оплаты труда являются параметрами инновационного цикла конверсии. Известно, что наиболее вероятной стоимостью продукции является ее рыночная цена, поэтому инновационная деятельность предприятия направлена на обеспечение равенства добавленной стоимости продукции и ее рыночной цены. Литейно-механическому заводу предложено организовать производство продукции путем трансферта на основе рыночного уклада технологических затрат и потребительских свойств продукции по переделам, являющихся зонами финансовой ответственности. При этом равновесие параметров операционного цикла конверсии необходимо реализовать путем электронно-цифровой системы управленческого учета.

Integrating cluster analysis with MCDM methods for the evaluation of local agricultural production
Authors: Nuri Omurbek , Akcakaya Onur , Urmak Akcakaya Ezgi Dilan
Published: December 2021

This study aims to cluster Turkish cities based on their local agricultural production and rank them in terms of performance by combining cluster analysis and multi-criteria decision-making (MCDM) methods. In this context, a three-phase methodology is developed. In the first phase, Ward's method is utilized to cluster cities according to agricultural production characteristics. In the second phase, the objective criteria weights are determined using the Criteria Importance Through Intercriteria Correlation technique (CRITIC). In the third phase, to rank the clusters in terms of performance, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is applied. Due to the results, the 81 cities are divided into six clusters in terms of agricultural production features. The cluster with the highest performance is Cluster 6, in which Konya is alone. Cluster 4, which includes Antalya and Mersin, follows this cluster. Cluster 1 with 25 cities and Cluster 2 with 19 cities are the clusters with the lowest results. The results show that only a few cities such as Konya, Antalya, and Mersin are generating more than tens of them in combination. These findings reveal that local governments should reconsider their agricultural programs and develop new strategies under the direction of the central government.
The Curricular Practical Training Rotation Problem Formulation and the Assessment of Rotation Strategies
Authors: Şimşek Ahmet Bahadır
Published: December 2021

This study addresses the curricular practical training rotation problem, which is a type of staff assignment problem. Many educational institutions require theoretical knowledge to be complemented by practical training. Although the details of the implementation differ from institution to institution, it is necessary to prepare a rotation plan that determines how long the trainees will practice in which unit in which training period. Because of the complexity of the problem and humanistic reasons, the manual rotation plan can not reach the optimal level that satisfies all stakeholders and takes time. This study defines a general Curricular Practical Training Rotation Planning Problem specific to the curriculum-based trainee assignment process carried out in a university department and proposes an integer mathematical model for its solution. It is one of the important contributions of this study. It also provides a methodological approach to identify the most appropriate rotation strategy that will satisfy stakeholders. The methodological approach followed is a structure that can be adapted to different perspectives. The study has the potential to guide practitioners and researchers in the field and to lead a rich literature that will be formed with different side constraints and purposes to the problem.
Flow Balancing in Modeling of Multi-Phase Flow using Non-Conformal Finite Element Meshes

The method of balancing numerical finite element flows in modeling a process of multiphase flow using non-conformal hexagonal meshes is considered. Studies have been carried out for a simple reservoir configuration and on a more complex model of a real field of high-viscosity oil in the Tatarstan. The research results showed that the balancing method allows one to obtain a conservative solution when using non-conformal finite element meshes with sufficiently large cells. At the same time, this method is completely free of problems associated with grid orientation, even for complex models containing zones with highly variable permeability. The proposed algorithm for the adaptive choice of parameters allows to do the factorization of the SLAE matrix at sufficiently small number of time steps; therefore, the computational costs of the flow balancing procedure are an order of magnitude less than the costs associated with calculating the pressure field and phase transfer. The used non-conformal finite element meshes with an arbitrary number of docked hexagons can significantly reduce the number of degrees of freedom when modeling multiphase flows in reservoirs with much small local heterogeneity and in the presence of several perforated zones. As a result, computational costs are reduced by almost an order of magnitude, and, at the same time, the required approximation accuracy is maintained. With an increase in the scale of the model and the number of operating wells, this advantage increases even more.
Methodological Aspects of Social Preferences Research in the Context of Solving Social Dilemmas
Authors:   Taras Shevchenko national University of Kyiv, Kovalenko Alla , Holovina Albina ,   Taras Shevchenko national University of Kyiv
Published: December 2021

The article presents an analysis of the main methodological principles and schemes of social preferences experimental research, which are determined as a fundamental concept to understanding the behavior of decision-makers in the process of resolving social dilemmas. The models presented in the article include an analysis of the factors that determine social preferences. Among them are the factors of trust, reliability, reciprocity, rejection of inequality, unconditional altruism and competitive advantage. The article provides a description of the strengths and weaknesses of the classic methods for studying social preferences, which usually take the form of ultimatum game, dictator game, trust game and public goods game. The study reveals the importance of the Nash equilibrium as a way to interpret human behavior in resource allocation during the game. Analysis of numerous literary sources shows that the ultimatum game is a classic scheme for studying the altruistic behavior of people. The submission of a proposal and its acceptance is an example of Nash's ideal equilibrium. Deviation from this balance can be interpreted as altruism. In turn, the trust game is a classic scheme for studying the reciprocity and prosocial orientation. If the behavior of players deviates from Nash's equilibrium, it is interpreted as being caused by trust and reciprocity. The dictator game is a classic scheme for studying the rejection of inequality. The subject's behavior can be interpreted as a rejection of inequality or altruism, but not as a rejection of risk, as the offer of Player 1 is mandatory for Player 2. Public goods game is a classic scheme for studying the competitive orientation. Nash's ideal balance in this form of play is to do nothing for public consumption, but deviating from this rule is interpreted as altruistic behavior that is the opposite of competitive orientation. As a result, the design of psychological research is presented, which most accurately typologies the social preferences of the subjects and can contribute to the creation of a representative model of decision-making process.
Factors of Personal Acquisition of Social Status in a Small Group in a Leisure Environment
Authors:   Taras Shevchenko national University of Kyiv, Lapshova Nataliia
Published: December 2021

The article presents the main results of an empirical study of the factors of personal acquisition of social status in a small group in the field of leisure. Reflecting the position of the individual in the system of society, the social status of the individual is determined by the set of rights and responsibilities of the individual in the context of social ties, groups and systems. Thus, social status is a component that simultaneously affects the individual, and which, in some way, depends on the individual. Since social status is a complex and multicomponent phenomenon, it was possible to determine its socio-psychological component structure. Social status was studied through sociometric positions of respondents. The entire sample was divided into 4 groups depending on the number of elections: neglected, rejected, accepted, stars. It was found that the factors of social status in the permissive context are the acceptance of others, the psychological climate of the team, focus on the present, social approval, lack of normative behavior (conformity). Factors of social status in the working context are personal characteristics and features of group dynamics, so it should be taken into account in combination with individual psychological characteristics. Factors of each social status for separate social groups were also singled out. The social status of the individual is an important component of the social life of every person. Its main function is to organize, design, regulate and conduct groups and their members. In the leisure environment for a group of technical professional orientation, the factors of acquiring social status for certain groups are the following characteristics: neglected – group cohesion, unaccepted – socio-psychological adaptation, accepted – the tendency to affiliation, stars – acceptance of others; for the group of humanitarian professional orientation: neglected – acceptance of others, unaccepted – group cohesion, accepted – the psychological climate of the group, the stars – emotional comfort.

Designing Electronic Card Packages Against Shipping Shock
Authors: Taylor Christine , Notohardjono Budy , Khambati Suraush , Canfield Shawn
Published: December 2021

In optimizing packaging design, the product’s fragility is qualified by a protype undergoing quantitative and qualitative tests that rely heavily on past knowledge and experiments. By the addition of finite element analysis (FEA), the product’s fragility can be obtained in the initial stages of product design with material characterization and simulation. FEA can predict Gs on the product as well as examine the strains, which interpret product failure more easily in the design stage. To incorporate FEA, first the foam material was measured at various strain rates under compression. Next a shipping package containing an Al block with consistent density was dropped at different heights—610 mm (24”), 915 mm (36”), and 1067 mm (42”)—to confirm the methodology. An I/O book was packaged for the final demonstration incorporating FEA with an electronic card package. In an electronic card package, the electronic assemblies are sensitive to strains on the system board. If the strains on the board are high, the assemblies’ solder connections to the board could be damaged and result in a defect during shipment. The simulations’ predicted Gs and board strains were compared to experimental drop testing results at 610 mm (24”) and 915 mm (36”). The simulation results for each sensor location were within reasonable approximation of the experimental results, verifying that FEA could be used in the initial design stages to predict the accelerations and strains for packaging development in parallel to the product design.

Authors: Popov E. V. , Anashbaev Zh. Zh. , Maltseva A. N. , Sazonova S. I.
Published: December 2021

Aim. To investigate the association of the radiomic characteristics of epicardial adipose tissue (EAT) on contrast-free computed tomography (CT) of the heart with the severity of obstructive coronary lesion and myocardial ischemia.

Methods. The study included 68 patients with coronary heart disease (mean age of 63.5±9.4, 45 men and 23 women), and 15 patients (mean age 30±4.8; 14 men and 1 woman) without cardiovascular disease as a control group. All the patients underwent multispiral computed coronary angiography, coronary calcium scores (CCS) determination and stress myocardial perfusion scintigraphy. Radiomic characteristics of EAT (texture analysis by gradations of gray color) were determined on non-contrast computer tomogram images of the heart using 3D-Sliser software and the SliserRadiomics module (version 4.10.2). The obtained indicators were compared between a control and under the study groups as well as between subgroups of patients divided according to the degree of obstruction of the coronary arteries, the size of the perfusion defect, and the value of the CCS.

Results. The comparative analysis of radiomic indicators of EAT between patients with coronary artery disease and the control group showed the presence of statistically significant differences between them. At the same time, the correlation analysis in the study group did not reveal any correlations between the radiomic parameters and the size of the perfusion defect, CCS or degree of stenosis of the lumen of the coronary arteries.

Conclusion. The textural characteristics of EAT in patients with coronary heart disease differ from those in individuals without cardiovascular pathology. At the same time, these indicators are not associated with the severity of obstructive lesions of the coronary arteries, the value of the CCS, and the size of the perfusion defect according to scintigraphy.
Dynamics of the number of myocardial revascularization operations in some countries in comparison with the Russian Federation in 2000–2018
Authors: Semenov V. Yu. , Samorodskaya I. V.
Published: December 2021

Aim. To study the dynamics of the number of coronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCI) in some countries and Russia in the 2000–2018..

Methods. The data of the official statistics of the Organization for Economic Cooperation and Development on the number of CABG and PCI were used. The countries that have provided data for most of the analyzed years and have more than 30 CABG per 100,000 population (22 countries) were selected. Data on the number of interventions in Russia were obtained from the CNIIOiIZ and Bakulev NMICSSH. The US data are obtained from the literature.

Results. In most countries, the number of CABG decreased by 2018.The United States, Denmark, Finland, Israel, and Luxembourg were the most variable in the average indicator. The most expressed decrease occurred in Finland (2.9 times). The number of PCI has increased significantly (in 9 countries by more than 2 times). The exception was the United States, where the number of PCI decreased by 2 times from 2003 to 2016. In Russia, there was an increase in CABG and PCI (by 10.2 and 50.5 times, respectively). The number of CABG and PCI per 100,000 population was 23 and 34 times less, respectively, in Russia than the international average in 2000, and 1.4 and 1.55 times less in 2018. The decrease in CABG is due to the improvement of PCI technologies, as well as the improvement of pharmaceutical treatment of coronary vessels. The number of proceedings, including court ones, on the validity of stent implantation is growing. The crosscountry variability of the use of cardiac surgical methods is influenced by the organizational and financial characteristics of the healthcare system, demographic and clinical characteristics of patients, the knowledge of doctors, etc. The experience of Russia fully confirms this.

Conclusion. There is no optimal method for accurately assessing the population's need for certain treatment methods. Each country chooses its own tactics, taking into account its resource capabilities, approaches to decision-making, its values and preferences, but the general trend is a decrease in the number of CABG operations while increasing the PCI. In Russia, there is a multiple increase in the number of CABG and PCI, but it is less than the indicators of most countries.

Aim. To make the first clinical experience evaluation of the new biological closed support ring for mitral valve.

Methods. 26 patients (16 men, 10 women, mean age 55 [49; 62] years) with dysplastic mitral insufficiency were implanted “NEORING” biological ring for the first time from March 2020 to June 2021. The etiological factor of the defect formation in all cases was the connective tissue dysplasia. The mean functional class of heart failure before surgery was 2 [2; 3] according to NYHA, the effective regurgitant orifice (ERO) was 0.4 [0.3; 0.5], vena contracta was 0.7 [0.6; 0.8]. Ten patients received rings of 28 mm diameter, ten patients – 30 mm, six patients – 32 mm.

Results. No significant adverse events such as death from any causes, strokes, myocardial infarction, cardiac complications, bleeding, and return of regurgitation or failure of plastic surgery requiring reoperation, infective endocarditis after the intervention were observed. In two cases a permanent pacemaker was implanted due to sinus node dysfunction. At discharge all patients had no regurgitation (ERO 0), medium transvalvular gradient was 4.0 [3.0; 5.3] mm Hg. All the patients were assigned to NYHA functional class I heart failure after the surgery.

Conclusion. New biological support ring “NEORING” (“NeoKor”, Kemerovo) use in the middle age group of patients showed high hemodynamic efficiency, the absence of specific complications in the early stages after the surgery. It is planned to expand the clinical material on the use of the biological ring, as well as to evaluate the long-term results in the format of a prospective, randomized trial and compare the new device with the existing ones.

Aim. To analyze in-hospital and long-term (12 months) results of percutaneous coronary intervention (PCI) supported by extracorporeal membrane oxygenation (ECMO) in patients with stable coronary heart disease and multivessel coronary artery disease, and to justify the use of such approach in the treatment of this group of patients.

Methods. The retrospective analysis included 13 patients with stable coronary artery and multivessel coronary disease. The mean SYNTAX score before the intervention was 31.4±10.8. Between 30 days and 12 months in the postoperative period, the frequency and type of the following major adverse cardiovascular events (MACE) was assessed: all-cause death, myocardial infarction, stroke, repeat revascularization. Twelve months after the event, the data on the frequency and type of adverse cardiovascular events were collected by means of telephone follow-up.

Results. Coronary intervention supported by ECMO was performed in all patients. 8 (61.6%) patients required an open surgical approach for ECMO cannula insertion. Door to balloon time was 109.6±79.2 minutes. The mean duration of ECMO support was 101.7±45.4 minutes. Haemodynamic instability, abnormalities in pulmonary gas exchange and rhythm disturbances were not revealed during primary PCI, making it possible to wean off the ECMO post-PCI. The mean residual SYNTAX score was 9.3±11.8. BARC class ≥3 bleeding complications were observed in 6 of 13 patients. Long-term major adverse cardiovascular events with fatal outcomes occurred in 3 (23.1%) patients.

Conclusion. Supporting high-risk PCI with ECMO in patients with stable coronary artery disease, multivessel coronary artery disease and low left ventricular ejection fraction made it possible to successfully perform the intervention in all patients. Nevertheless, the long-term (12 months) results show a high percentage of recurrent myocardial infarction, which can be associated with high residual SYNTAX score.
Рок-культура и сексуальность: характер взаимосвязи
Authors: Дюкин Сергей Габдульсаматович
Published: December 2021

Эволюция сексуальности как социокультурного феномена на современном этапе развития культуры является атрибутом трансформации социальных отношений. Преобразование практик, связанных с интимностью, превращение избыточной сексуальности в норму сопряжены с воздействием тех или иных факторов культуры, служащих катализаторами обозначенных процессов.

Гипотеза исследования заключается в том, что одним из определяющих ресурсов эволюции сексуальности является рок-культура, предопределяющая многоуровневую трансформацию интимности. Ведущим мотивом изменений является радикальная эмансипация сексуальности, обретение ею избыточного экстенсивного характера и статуса этического императива в рамках рок-культуры. Катализатором половой активности в биографических нарративах выступает избыточный престиж, формирующийся вокруг профессиональных практик музыкантов. Музыканты подаются как своеобразные центры новой чувственности. Данная позиция фиксируется через образ жизни, в рамках которого пластичный секс превращается в доминирующую поведенческую стратегию. Производным процессом, связанным с акцентированным вниманием субъекта на интимных связях, становятся демократизация и ориентация на горизонтальный тип отношений, исключающий иерархизацию социума. Другой становится для субъекта не объектом активного действия, а абсолютно равным партнером.
Социологическое изучение религиозности в детской и в молодежной среде в Среднем Поволжье в позднесоветский период
Authors: Кильдеев Мансур Вилевич
Published: December 2021

Цель исследования — рассмотреть специфику социологического изучения мировоззрения детей и молодежи на материале советской социологии религии. Научная новизна заключается в том, что социологические данные использованы как источник данных о том, как в детской и молодежной среде преломлялись общественные тенденции секуляризации, идеологического диктата и воспроизводства религиозности. Наиболее заметным итогом опросов в школьных стенах является то, что они проходили с игнорированием юридических и этических норм участия несовершеннолетних в научных исследованиях. Имеющийся материал изучения молодежи позволил провести сопоставительный анализ состояния мировоззрения советской молодежи с одной стороны, в татарской среде Горьковской области, с другой — в интернациональной среде студенчества г. Казани. Данные позволяют утверждать о значительной степени секуляризованности интернационального советского студенчества, которое в приведенном кейсе на 80% состояло из выходцев из семей служащих и рабочих. Зафисированы также непредвиденные результаты социализации советской молодежи в виде широкого распространения идеологического конформизма и религиозного индифферентизма. Однако вопреки аксиомам советское общество не было однородным. В нем во все времена существовали социальные анклавы, на которые не распространялись общие социальные тенденции. Так, татарская молодежь Горьковской области находилась под сильным влиянием мусульманской религии.
Хоровая культура как культурологический концепт
Authors: Албанов Иван Алексеевич , Лях Валентина Ивановна
Published: December 2021

В статье представлена сложная разноуровневая структура хоровой культуры в динамике ее развития: от традиций к современности. Хоровая культура рассмотрена как культурологический концепт, который является основой понимания и формирования различных картин мира, ценностных приоритетов. Культурологическая трактовка позволила выявить ключевые параметры концепта «хоровая культура»: изменения внутренней, духовной жизни личности, ее специфические особенности. Методологическую основу исследования составил системный подход в сочетании с другими подходами: лингвокультурным, когнитивным, философским, культурологическим.

Автором рассмотрены исторические тенденции развития хоровой культуры в России от хоровых музыкальных традиций прошлого до современного неоклассицизма. Определены структурные компоненты концепта «хоровая культура»: исполнение духовных произведений; хоровые фольклорные формы, самодеятельное творчество, русский хоровой неоклассицизм. Отмечен региональный уровень научных знаний о хоровой культуре, который реализуется в обучении и профессиональной подготовке. Большое внимание уделено системе нравственных и морально-этических составляющих концепта «хоровая культура».

Conocimientos matemáticos del profesorado de la Escuela Infantil (0-3 años): efecto en el diseño de espacios para desarrollar las matemáticas informales
Authors: Olmos Martínez Gloria , Alsina Ángel
Published: December 2021

En este estudio se analizan los conocimientos matemáticos del profesorado de la Escuela Infantil para favorecer el desarrollo de los primeros conocimientos matemáticos intuitivos e informales de los niños y niñas de 0 a 3 años, a través del diseño de los espacios y materiales. Se ha diseñado un estudio cuasi-experimental (Pre-Post) en el que, antes y después de una actividad de formación, se ha administrado el Cuestionario “Conocimientos Didáctico-Matemáticos en la Escuela Infantil” (CDM 0-3) a 28 profesionales. Los resultados obtenidos muestran cambios significativos en los conocimientos matemáticos y, por consiguiente, en el diseño de los espacios y materiales que se ofrecen a los niños y las niñas de 0 a 3 años, incrementando el contenido y sentido matemático. Se concluye que es imprescindible una formación inicial y continua de calidad que garantice que los profesionales de la Escuela Infantil tengan los conocimientos matemáticos necesarios para diseñar espacios ricos desde un punto de vista matemático.
Social Distancing with the Optimal Steps Model
Authors: Mayr Christina Maria , Köster Gerta
Published: December 2021

With the Covid-19 pandemic, an urgent need has arisen to simulate social distancing. The Optimal Steps Model (OSM) is a pedestrian locomotion model that operationalizes an individual's need for personal space. We present new parameter values for personal space in the OSM to simulate social distancing in the pedestrian dynamics simulator Vadere. Our approach is pragmatic. We consider two use cases: in the first, we demand that a set social distance must never be violated. In the second the social distance can be violated temporarily for less than 10s. For each use case we conduct simulation studies in a typical bottleneck scenario and measure contact times, that is, violations of the social distance rule.We conduct regression analysis to assess how the parameter choice depends on the desired social distance and the corridor width. We find that evacuation time increases linearly with the width of the repulsion potential, which is an analogy to physics modeling the strength of the need for personal space. The evacuation time decreases linearly with larger corridor width. The influence of the corridor width on the evacuation time is smaller than the influence of the range of the repulsion, that is, the need for personal space. If the repulsion is too strong, we observe clogging effects.  Our regression formulas enable Vadere users to conduct their own studies without understanding the intricacies of the OSM implementation and without extensive parameter adjustment.

Some Unexpected but Conspicuous Shortcomings in Toni Morrison’s Last Novel
Authors: Ibarrola-Armendariz Aitor
Published: December 2021

In the last five decades, Toni Morrison’s fiction has covered such intricate topics as the impact of the past on the present, the damage produced on bodies and minds by different types of abuses, and the power and perils of small communities. She revisits some of those themes in her last novel, "God Help the Child" (2015), but this time zooms in more closely on the topics of child abuse and colorism – an internal racism of blacks against those with darker skin shades. "God Help the Child" proves innovative because the story is set in presentday fictional California, where the rate of child molestation – especially against black children – is just overwhelming. This article intends to show that, despite Morrison’s audacious narrative form and storytelling skills, there are some evident shortcomings in the structure and characterization of the novel that are not to be found in her earlier works.
Posthumanist Trauma: An Intrasectional Approach to Accountable Determinacy in Current North American Narrative
Authors: Fernández-Santiago Miriam
Published: December 2021

How can we deal with trauma in a posthuman world? The 9th of September 2001 will be remembered as the day the world changed. The turn of the century in the Western world was signaled by this national trauma, but also by a change in the humanist paradigm that very much conditioned the way in which such trauma was experienced and represented. This article explores this intrasection in the works of Thomas Pynchon and Art Spiegelman as they struggle to account for 9/11 through two trauma narratives that signal a matching change in aesthetic approach. Its methodological innovation lies in the application of Karen Barad’s concept of “intra-action” to the humanities.
The Quest for Whiteness in Willa Cather’s "My Ántonia" (1918) and Henry Roth’s "Call It Sleep" (1934)
Authors: Vives Martínez Mireia
Published: December 2021

The aim of this paper is to trace the assimilation process of European immigrants to the United States at the turn of the century in Willa Cather’s My Antonia (1918) and Henry Roth’s Call It Sleep (1934). Bearing in mind the historical relevance of race and whiteness in the United States, I analyse the changes performed by Cather’s and Roth’s protagonists in order to achieve the status of white. To this purpose, I provide a brief overview of the nature of whiteness in the United States and its epistemological changes to account for its importance within the novels. I then look at the transformations characters perform in terms of religious faith and gender norms, as well as their interaction with English and spaces to become integrated in the new land. In doing so, differences between the novels arise, but so does a subtext of violence common to the immigrant experience.
