Cycling Planning in Small-Sized Brazilian Cities Based on Open Data Geoprocessing
Authors: Monari Marcelo , Segantine Paulo César Lima
Published: June 2022

The objective of this paper is to propose a method to systematize cycling planning in small-sized Brazilian cities based on open data, such as census data, collaborative mappings, and Digital Elevation Models, seeking to assist in the elaboration of municipal urban mobility plans, and that can be adapted to other countries with similar characteristics and that have equivalent information. The proposed method is summarized in four steps: geoprocessing of open spatial data, which allows the georeferencing of potential cycling demand and cycling trip generator poles, as well as updated representations of road systems; definition of the subsets of origins and destinations of the cycling routes to be identified using Dijkstra’s algorithm, in order to minimize the overall cost associated with the road segments' operational quality for cycling; impedance assignment to road segments based on their average slopes and cycling Levels of Traffic Stress; and assessment of these road segments’ proportions in the identified cycling routes (Cycling Potential Index). Examples of the proposed method’s application were carried out in two Brazilian cities, Bariri-SP and Bocaina-SP, through which it was possible to define, for both cities, continuous and interconnected cycling axles, accessible to most of the study areas’ potential cyclists. Therefore, despite the obvious importance of conducting specific research and field surveys in each Brazilian city for greater reliability of the results, the proposed method can contribute to the popularization of cycling in utilitarian trips and to the strengthening of the “bicycle culture” still in force in small-sized Brazilian cities.

Factors affecting English-speaking learners’ acquisition of Chinese relative clauses with demonstrative classifier phrases
Authors: Du Hui-Ming Lois , Chen Chun-Yin Doris , Hsieh Fang-Yen
Published: June 2022

The current empirical research aimed to investigate native English-speaking learners’ acquisition of Chinese relative clauses (RCs) by conducting two studies. Study I explored the participants’ performance on gapped and gapless relative clauses (RCs) and their interpretation of demonstrative classifier (DCL)-relative clauses. Study II further investigated the participants’ interpretation of DCL-first and DCL-second RCs and discussed contextual effect. Different tasks were designed in the two studies: a sentence-unscrambling (SU) task and an acceptability judgement (AJ) task in Study I; and an interpretation (IT) task in Study II. A total of 20 L2 learners and 20 native speakers of Mandarin participated in our research. The overall results obtained from Study I revealed that gapped RCs were easier to produce and accept than gapless RCs, and learner performance was influenced by DCL position. Moreover, the L2 learners’ L1 knowledge was found to affect their production, but the task effect was not significant. In Study II, DCL-first RCs were found to be as difficult as DCL-second RCs for the L2 learners to interpret. The non-restrictive and restrictive interpretations of DCL-first RCs were found to be much more comprehensible. Finally, the L2 learners’ interpretation of RCs having DCL phrases in different positions showed a tendency of a contextual effect.
An unusual case of the congenital mesenchymal hamartoma of the neck associated with the midline cervical cleft in neonate
Authors: Nađ Ida , Šijak Dorotea , Jurica Sonja Anić , Jakovčević Antonia
Published: June 2022

Objectives

Hamartomas are non-neoplastic developmental anomalies, mostly congenital, characterized by uncontrolled, disorganized proliferation of local endogenous tissue, which can normally be found at the site of origin and are very often mesodermally derived. It is well known that hamartoma can be associated with congenital midline cervical cleft and therefore cause a variety of symptoms. In general, they are benign and indolent, but they can be the cause of complex morbidity if they are localized within specific regions, such as the head and neck, which represent highly sensitive and vulnerable areas.

Case presentation

The reported case is unusual because of the presence of a congenital mesenchymal hamartoma along with the median cervical cleft, in a 1-day-old neonate, without the presence of any respiratory symptoms or associated congenital features. Although extremely rare, hamartomas should be included in the differential diagnosis of congenital neck masses, with emphasis on diagnostic approach, to avoid overly aggressive treatment and possible complications, such as infection, further mass growth, malignant transformation and compression of the adjacent neck structures.

Conclusions

Appropriate and timely treatment of the hamartoma of the neck in neonates, with further follow-up is necessary to avoid an overly aggressive treatment and to distinguish benign from malignant lesions, which is necessary for successful curative outcome.
Influence of selected physical parameters on vibroinsulation of base-exited vibratory conveyors
Authors: Czubak Piotr , Gajowy Marek
Published: June 2022

Vibrating conveyors tend to transfer dynamic forces to the ground. One way to vibroinsulate such systems from the environment is to use dynamic methods to eliminate vibrations. Due to this phenomenon, the forces transferred to the ground are reduced. This article attempts to identify important elements determining the design of an antiresonance-type conveyor. The study of dynamic phenomena was based on two models of such conveyors with two and six degrees of freedom (with the phenomenon of self-synchronization). In this work, the impacts of various types of suspension and the ratio of the body mass to the mass of the conveyor trough on forces transmitted to the ground are analysed.

In this work, synthesis, characterization, DFT, TD-DFT study of some novel reactive azobenzoquinoline dye structures to elucidate their photovoltaic properties. The azobenzoquinoline compounds were experimentally synthesized through a series of reaction routes starting from acenaphthene to obtained aminododecylnaphthalimide and finally coupled with diazonium salts to get the desired azobenzoquinoline. Azo dye synthesized differ in the number of alkyl chains designated as (AR1, AR2, AR3, and AR4) which were experimentally analyzed using FT-IR and NMR spectroscopic methods. The synthesized structures were modelled for computational investigation using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) combined with B3LYP and 6-31+G(d) basis set level of theory. The results showed that the HOMO-LUMO energy gap was steady at approximately 2.8 eV as the alkyl chain increases, which has been proven to be within the material energy gap limit for application in photovoltaic. The highest intramolecular natural bond orbital (NBO) for the studied compounds is 27.60, 55.06, 55.06, and 55.04 kcal/mol for AR1, AR2, AR3, and AR4 respectively and the donor and acceptor interacting orbitals for the highest stabilization energy (E
(2)) are LP(1)N
18 and π*C
16−O
19 respectively. The photovoltaic properties in terms of light-harvesting efficiency (LHE), Short circuit current density (J
SC), Gibbs free energy of injection (ΔG
inj), open-circuit voltage (V
OC) and Gibbs free energy of regeneration (ΔG
reg) were evaluated to be within the required limit for DSSC design. Overall, the obtained theoretical photovoltaic results were compared with other experimental and computational findings, thus, are in excellent agreement for organic solar cell design.

Memory, Narrative and the Search for Identity in Psychoanalytic Psychotherapy: A Second Chance
Authors: Kestenbaum Clarice J.
Published: June 2022

The need to create order out of chaos is a driving force, ethologicalty determined, and part of the human condition. Narrative, especially autobiography and self narrative, helps us sort out myriad fantasies, events, and images, weaving them into a cohesive whole that eventually promotes self-awareness. The narratives of Virginia Woolf, St. Augustine, and Samuel Beckett are briefly described. Attachment theory and current research demonstrates that secure attachment is a first step in the socialization process and helps put one’s life in perspective. The therapeutic use of narrative is demonstrated by three clinical vignettes of patients with various psychiatric disorders who had successful therapeutic outcomes.
Attachment Relationships as Determinants of Physical Health
Authors: Maunder Robert G. , Hunter Jonathan J.
Published: June 2022

Childhood adversity alters the relational world of the child and inhibits the development of secure attachment bonds. The purpose of this article is to survey recent evidence that attachment insecurity has the potential to impair physical health throughout the lifespan. It is proposed that attachment insecurity contributes to disease risk through a range of mechanisms which include (1) disturbances in arousal and recovery within physiological systems that respond to stress; (2) physiological links between the mediators of social relationships, stress, and immunity; (3) links between relationship style and various health behaviors; and (4) disease risk factors that serve as external regulators of dysphoric affect, such as nicotine and alcohol. The evidence for these mechanisms, particularly the evidence that has accumulated since the model was first proposed in 2000, is presented and discussed.
Reimagining Energy in the Information Age
Authors: Holt Nicolas
Published: June 2022

In the late 1960s, Chilean media artist Juan Downey constructed a series of electronic sculptures that aimed to render their invisible electromagnetic environment perceptible for spectators. Designed to transform radar waves or cosmic background radiation into light, sound, and mechanical vibration through sensors and transmitters, these sculptures allow us to rethink the relation between energy and the dematerializing logic of the cybernetic paradigm that has come to dominate the existing scholarship on conceptual and media arts. The existing scholarship of Downey’s electronic sculptures frames them as realizing contemporary theories of cybernetic communication and feedback: facilitating participation among bodies and technologies to generate an informational assemblage. This article, however, asserts that the deployment of the cybernetic paradigm of information in this art historical scholarship inadvertently reproduces cybernetics’ historical de-emphasis of material and energetic specificity, and thus fails to account for those insights that emerge from Downey’s unique attention to the concrete reality of electromagnetism and its interactions with human perceptual experience and technical media. In this article I argue that the electronic sculptures invoke specific frequencies of the electromagnetic field, not to dematerialize them into flows of information, but to foreground their challenging materiality and reveal the limits of our organic and technological modes of access to a vast and elusive yet animating energetic environment. My objective is to open up Downey’s early practice to new concerns outside the cybernetic frame, with a special focus on his contributions to the link between art history and the energy humanities.

The retrovirus HIV‐1 integrates into the host genome and establishes a latent viral reservoir that escapes immune surveillance. Molecular mechanisms of HIV‐1 latency have been studied extensively to achieve a cure for the acquired immunodeficiency syndrome (AIDS). Latency‐reversing agents (LRAs) have been developed to reactivate and eliminate the latent reservoir by the immune system. To develop more promising LRAs, it is essential to evaluate new therapeutic targets. Here, we find that CBX4, a component of the Polycomb Repressive Complex 1 (PRC1), contributes to HIV‐1 latency in seven latency models and primary CD4+ T cells. CBX4 forms nuclear bodies with liquid–liquid phase separation (LLPS) properties on the HIV‐1 long terminal repeat (LTR) and recruits EZH2, the catalytic subunit of PRC2. CBX4 SUMOylates EZH2 utilizing its SUMO E3 ligase activity, thereby enhancing the H3K27 methyltransferase activity of EZH2. Our results indicate that CBX4 acts as a bridge between the repressor complexes PRC1 and PRC2 that act synergistically to maintain HIV‐1 latency. Dissolution of phase‐separated CBX4 bodies could be a potential intervention to reactivate latent HIV‐1.
Europski platni nalog - naplata dospjelih novčanih potraživanja od stranih pravnih i fizičkih osoba
Authors: Nižić-Peroš Jadranka
Published: June 2022

Predmet ovog rada je analiza zakonskog uređenja i sudske prakse u svezi izdavanja europskog platnog naloga te je svrha ovog rada pružiti poticaj pravnim i fizičkim osobama za buduće korištenje ovog instrumenta koji se primjenjuje u Republici Hrvatskoj od dana pristupanja Europskoj Uniji, od srpnja 2013., a koji se koristi u izuzetno malom broju slučajeva. Za izdavanje europskog platnog naloga u Republici Hrvatskoj su nadležni sudovi te se radi o instrumentu kojim se naplaćuje tražbina od  stranih pravnih i fizičkih osoba, dužnika, bez potrebe znanja jezika Europske unije. Stoga se upravo primjenom postupka izdavanja platnog naloga omogućuje jednostavna, brza i  jeftina sudska naplata tražbine od dužnika sa pretpostavkom da tražbina neće biti osporena od strane dužnika. Europski platni nalog je alternativni postupak u odnosu na postupak koji se provodi na nacionalnoj razini te je najveća prednost ovog postupka njegova praktičnost jer je potrebno podnijeti samo jedan zahtjev na propisanom obrascu dostupnom na jezicima svih zemalja Europske unije, a koji obrazac je svima dostupan na internetskom portalu e-pravosuđe. U radu se analizira izdavanje platnog naloga od strane država članica Europske unije, osim Danske, obzirom da vjerovnici iz Republike Hrvatske mogu tražiti izdavanje europskog platnog naloga protiv svojih dužnika neposredno u svim ostalim državama članicama Europske unije. Polazi se od stajališta da u poslovnom svijetu veliki problem predstavljaju nenaplaćena dospjela potraživanja prema stranim pravnim i fizičkim osobama te da je ulaskom u Europsku uniju vjerovnicima omogućeno da naplate svoja potraživanja prema dužnicima koji žive u nekoj od zemalja Europske unije na brz i jednostavan način, a o čemu prema mišljenju autora, vjerovnici nemaju dovoljna saznanja. Primjena Uredbe (EZ) br. 1896/2006 kojom se regulira postupak izdavanja europskog platnog naloga je od iznimne važnosti upravo iz razloga što se njezinom primjenom osiguravaju jednaki uvjeti naplate nespornih (neosporenih) građanskih i trgovačkih tražbina na području cijele Europske unije osim Danske.

Published: June 2022

Genocide is one of the crimes that are included in gross violations of human hights where this crime is related to ethnic cleansing which is also included in crimes against various political groups because it is difficult to identify which causes an international problem in a country. The crime of genocide in international criminal law is an extraordinary crime and is a prohibited act which was later included in the 1948 Genocide Convention, the statutes of the International Criminal Tribunals for the Former Yugoslavia (ICTY), the statutes of the International Criminal Tribunals for the Rwanda (ICTR) and the 1998 Rome statute. This study is intended to analyze the crime of genoside in the perspective of international law. This study found that the analysis and discourse of genoside in intersected with human rights theory and state responsibility. Genocide also highlighted as international crimes that are included in 4 (four) international crimes, namely genocide, crimes against humanity, war crimes, and crimes of aggression. In the Indonesian National Law Regulation, the Law of the Republic of Indonesia Number 26 of 2000 concerning the Human Rights Court in Article 7 states, the Crime of Genocide is a grave violation of human rights.
Imposing Additional Criminal Sanction of Chemical Castration against Child Sexual Violence Perpetrators
Authors: Hardianti Firda Yanis , Rusdiana Emmilia
Published: June 2022

This paper aims to examine the fulfillment of the requirements for implementing the judge's decision Number: 69/Pid.Sus/2019/PN Mjk in providing additional punishment in the form of chemical castration and rationalization of the Indonesian Doctors Association (IDI) in approving the implementation of the decision. The results of the study indicate that the conditions for implementing the decision No. 69/Pid.Sus/2019/Pn Mjk in providing additional punishment for chemical castration has been fulfilled, because the conditions for the imposition of additional punishment in the form of chemical castration are imposed after the convict has served the principal sentence in accordance with Article 81A paragraph (1) of Law Number 17 of 2016 concerning child protection. The reason IDI is obliged to approve the implementation of Decision Number: 69/Pid.Sus/2019/PN Mjk is that when a regulation is included in the legislation, this provision is perfectly binding and must be obeyed. So, in practice, when a doctor is asked to perform chemical castration, the doctor must do so because this provision is a legal order and there is a justification for this. The decision Sus/2019/PN Mjk is when a regulation is included in the legislation, this provision is perfectly binding and must be obeyed.

This study aims to validate and analyze the accuracy of sentencing the the defendant as the head of the service in fulfilling the elements of the legal subject as a Civil Servant, as well as legal proof of the defendant's actions which are considered beneficial or detrimental to one of the candidate pairs. Legal research with normative juridical, as well as statutory, case, and conceptual approaches and analyzed prescriptively. The accuracy of sentencing the the defendant in Decision Number 147/Pid.Sus/2018/PN.Sdr regarding legal subjects is based that the Panel of a judge s interprets ASN holding certain positions in government as ASN. The judge's considerations did not refer to the Civil Servant Law and the the defendant was a High Pratama Official, belonging to an Echelon 2 position, and this was based on the theory of a criminal responsibility that the actions taken by the the defendant were a burden of personal responsibility not the responsibility of the position. It has nothing to do with the main duties and official functions as Head of the Social, Civil and Population Registration Service, and not as a legitimate job order task. Legal proof of the the phrase "favorable" or "detrimental" to one of the Candidate pairs is inappropriate, because it is not based on the benefit or harm is a formal offense so it does not need to be proven because there is a potential loss and at the same time the theory of  economics analysis of law on the principle of optimization, proving cost-benefit analysis, the principle of balance, and the principle of efficiency.

Authors: Rohmat Rohmat , Ashtaputre Shrirang , Smith Robert Brian
Published: June 2022

No one wants a crime to occur in their community, because the existence of this crime will be disturbing and detrimental to people's lives. Therefore, crime must be tackled and stopped. This article discusses cases of adolescent delinquency, burglary crimes and labeling practices in the study of criminological theories. It is important to understand cases of adolescent delinquency, crime of robbery and labeling practices in terms of the characteristics of crime and criminals. The research method used is a normative juridical research method with secondary data sources. The results showed that there were 5 (five) theories that could be used to analyze adolescent delinquency cases, namely the French sect, differential association, anomie, social control, and learning theory. While the crime of robbery is analyzed in 4 (four) theories, namely classical criminology theory, positive criminology, differential association, and opportunity theory. Meanwhile, the case of labeling in society was studied using labeling theory. The above theories can be used as a strategy to prevent and prosecute juvenile crimes, in this case juvenile brawls as a special crime, burglary crimes, and community labeling practices. It can be concluded that increasing family participation as the first medium of learning for children by increasing control, so that brawls between teenagers can be anticipated, as well as increasing community participation and social control as well as preventive, curative, and repressive actions to prevent actions that violate social norms and legal norms.

The execution of court decisions especially for confiscated objects and state spoils face some challenges in Indonesia. This research aims to find out the the executive of court decisions in the return of evidence, as well as what factors affect the presecutor as the executor of the court’s decision. The research questions formulated as first, what is the role of the presecutor in carrying out of the execution of the court's verdict on the return of evidence? and second, what are the factors that affect the presecutor as the executor of the court's decision in the return of evidence? The research method used in this research is qualitative research method with a type of socio-legal studies. This research found and highlighted that the execution of the court’s decision on the status of the evidence carried out by the Prosecutor after the adjudicator's decision has been signed. There are four factors that influence the level of effectiveness of the Prosecutor as the executor of court decisions with regard to evidence, including the legal factor itself, the community factor, the law enforcement officer factor, as well as the legal facilities and facilities factor. Various regulations have been drafted, however, none of them have explicitly regulated the threat of sanctions for prosecutors who do not immediately carry out executions, lack of coordination between related parties, and limited legal facilities and facilities are factors that affect the effectiveness of prosecutors in carrying out their duties.

La clasificación de los productos en categorías se realiza de acuerdo a su importancia o relevancia por algún tipo de criterio, que normalmente es el consumo o utilización anual (para materias primas o repuestos) o la demanda o las ventas anuales (para productos terminados), utilizando para esto el bien conocido principio de Pareto. Sin embargo, en ocasiones es altamente recomendable y necesario hacer uso de criterios adicionales que permitan realizar una diferenciación más efectiva de las existencias. Por ello, este artículo presenta una recopilación de criterios útiles para realizar la clasificación ABC del inventario, describe en qué consiste cada uno y cómo puede ser medido. Adicionalmente se muestra un ejemplo de un escenario crítico de una clasificación ABC con tres criterios, en donde de acuerdo a los pesos asignados a cada uno y de las características de los productos incluidos en el proceso de clasificación, se pierde la validez de algún criterio en el análisis.
Algoritmo para generación de controladores difusos interpretables. Aplicación a un proceso de presión
Authors: Contreras Montes Juan Antonio , Muñoz Aldana David Javier
Published: June 2022

En este artículo se presenta una novedosa metodología para la generación de controladores difusos tipo singleton a partir de datos experimentales de entrada y salida. Se describe una técnica para construcción de las reglas difusas mediante funciones de pertenencia triangulares, con interpolación en 0.5, para la partición de los antecedentes; mínimos cuadrados para el ajuste de los consecuentes tipo singleton y operadores tipo promedio ponderado, en vez de operadores tipo t-norma. El aspecto más promisorio de la propuesta consiste en la obtención del modelo, o controlador difuso, sin sacrificar su interpretabilidad ni recurrir a otras técnicas de inteligencia artificial. Para llevar a cabo el entrenamiento del controlador difuso se utilizó el sistema de presión del sistema didáctico en control de procesos de Lab-Volt, modelo 6090. Los datos de entrenamiento fueron tomados de una experiencia realizada con un control PI.

Una de las principales necesidades, actualmente en Colombia, tiene lugar en el proceso de planeación de redes inalámbricas, por lo cual mediante el proyecto Gisgerram se busca crear un servicio de telecomunicaciones que permita la planificación de redes de antenas celulares a través de un servidor remoto. Sin embargo, para poder lograrlo es necesaria primero la verificación de las herramientas que serán usadas para este servicio. Dentro de este macroproyecto se desarrolló el CellGis, en este artículo se describe la validación de dicha herramienta en la región andina, mediante la ejecución de campañas de medición real de potencia en 4 zonas de Bucaramanga, y el contraste con las simulaciones arrojadas por CellGis con el fin de analizar el funcionamiento del simulador de radiopropagación con el algoritmo AndinoUis implementado, lo cual permitió la deducción de falencias. De esta forma, se realizaron las modificaciones necesarias para la correcta utilización del patrón de radiación, mediante las mediciones se determinaron algunos efectos que el algoritmo no tiene en cuenta, de forma que en trabajos futuros se puedan programar e implementar nuevos algoritmos que incluyan dichos factores. Paralelamente, se tomaron mediciones de radiación no ionizante en diferentes zonas de Bucaramanga, y posteriormente se verificaron los valores obtenidos con las normas que regulan la exposición con el fin de comprobar su debido cumplimiento.
Epistle of Pope Sixtus (Xistus) III to Proclus, archbishop of Constantinople
Authors: Anashkin Anton
Published: June 2022

This work includes a translation from Latin of the epistle of Pope Sixtus (Xistus) III to Archbishop Proclus of Constantinople (437), as well as an introductory article and historical and philological commentaries. There is an information about the author and the addressee of the epistle at the beginning of the article; then its analysis is given. The epistle sheds light on the relationships between the Roman See and the See of Constantinople and the See of Thessalonica in the 430s, and also provides a better understanding of the role of the Vicariate of Thessalonica in its relationship with the Churches of Rome and Constantinople. The text was probably written as a reaction to the appeal of the Illyrian bishops to the see of Constantinople, bypassing Anastasius of Thessalonica. Turning to Proclus, Sixtus defends the jurisdictional rights of the Archbishop of Thessalonica as papal vicar in Illyricum. At the same time, Illyricum is considered by Sixtus as a region subordinate to the See of Thessalonica, as the Pope stated in his other letters. The work emphasizes the connection of the epistle with other letters of Pope Sixtus (among them Si quantum, Gratulari potius and Doctor gentium). Sixtus reminds Proclus about an incident with bishop Idduas of Smyrna as well as about his support for the judgment of the Primate of Constantinople. It seems that by this Sixtus hoped to induce Proclus to act similarly in such situations when the Illyrian bishops could turn to Constantinople looking for its support. Sixtus calls on Proclus to support Anastasius in his rights and not to accept the bishops of his region without official letters (formatae).
“I remain sincere friend of the Russian Orthodox Church Abroad”. Letters from hieromonk Vasily (Rodzianko) to protopresbyter Georgy Grabbe
Authors: Kostryukov Andrey
Published: June 2022

This article makes public the letters of Revd. Vladimir Rodzianko (Hieromonk Vasily) to Protopresbyter Georgy Grabbe. Both the sender and the addressee are wellknown. The former is the future bishop and a long-term prsenter of Orthodox programmes on BBC Radio. The former also became a bishop, and for many years was the secretary of the Synod of Bishops of the Russian Church Abroad having a great infl uence on its policy. The letters were written in the early 1979 in the moment of great changes in the life of their author. The fi rst letter was prepared when he was Protopriest Vladimir, the second soon after his becoming a monk as Hieromonk Vasily. The reason for the letters were the attacks of the administration of the Russian Church Abroad against Moscow Patriarchate as well as the idea, popular in the Russian Orthodox Church, that there is no holy grace at all in any communities not belonging to the Orthodox Church. This idea was put forward by Protopresbyter G. Grabbe in the article Acribeia and Oeconomy. This approach was aggravated by the fact that the administration of the Russian Church Abroad regarded as apostate the clergy of Moscow Patriarchate. The consequence was an idea about their gracelessness. Hieromonk Vasily (Rodzianko) thought that this was erroneous and dangerous. Using certain historical evidence and an opinion of St. Ioann (Maksimovich), he claimed that the Orthodox gaith and the Eucharist are supreme over the jurisdictional controversies and that the temporary discord does not aff ect grace. The letters contain interesting facts as to relations between the Russian Church Abroad and the Serbian Church in the 1920s — 1940s, describe little-known details between the Russian Church Abroad and other branches of Russian church in exile.
Stratification of the russian landed nobility in the middle — second half of the 18th century
Authors: Feofanov Alexander
Published: June 2022

The study is based on the materials preserved in Fund 16 of the Russian State Archive of Ancient Acts (RGADA). They indicate the age, property status (number of serf”s souls), geographical location of their estates (in which county were the estates) and the place where they were assigned for service (army, guards, navy, etc.) or in an educational institution. A total of 8,762 noblemen were reckoned. The overwhelming majority of landlords had possessions in only one county. The median value of soul-ownership of all the nobles was 14 souls, for the landlords – 23 souls. More than 20 percent of the nobility had no peasants in their ownership. Landlords (who had over 100 souls) accounted for slightly more than 12 percent of all noblemen and about 16 percent of serf-owners alone. Of all the landlords, less than 1 percent were the descendants of the Duma officials of the Tzardom of Russia. Exactly half of them had the title of kniaz (prince), almost 60 percent were the children of military and civilian generals. They were very rich landlords, 92 percent had more than 500 souls, more than 78 percent owned more than 1,000 souls. Representatives of the titled nobility, namely, princes, numbered a little more than 2 percent of the total mass of landlords. A quarter of them belonged to the large landed gentry. In general, large landlords accounted for 2.5 percent of the total number of nobles, a third part of them were the descendants of the Duma officials. Magnates who owned a thousand souls or more made up just over 1 percent of the total mass of nobles, of which the descendants of Duma officials made up almost 60 percent. The future generals of the undergraduates of 1743–1750 were less than 3 percent, half of them came from families of landowners who owned less than a hundred souls. Of the children of generals (the first three ranks) almost 90 percent may be considered as large landlords, the owners of more than 1 thousand souls were 72 percent. At the same time, of the descendants of non-aristocratic nobles – sons of generals (of the first three ranks), the owners of more than a thousand souls were only 42 percent. These figures clearly show the conjugation of having large quantities of serfs and gentility. To be of noble origin was even more important than to have a rank of a general.
