Strategies for Reading Visual Poetry: A Semiotic Approach and Its Practical Application
Authors: Katkuvienė Jurgita
Published: February 2023

The article explores the ways in which the Greimasian method of semiotics can be applied to the analysis of contemporary Lithuanian poetry texts, specifically visual poetry. Bearing in mind the nature of visual poetry, I consider a semiotic approach, which allows explaining the strategies of meaning making in visual poetry. The methodological question goes back to the origins of Algirdas Julius Greimas’ semiotics, in particular the works of Louis Hjelmslev. I draw attention that based on Hjelmslev’s approach, it is important not only to treat any unit of meaning as a certain relationship between the plane of content and the plane of expression, but in the case of visual poetry, also to supplement it with a more detailed description of Hjelmslev’s levels of language (form–substance–purport) and their interrelations. It calls attention to the plane of expression, which has a special status in visual poetry. I argue that one of the most important conditions for the emergence of signification in visual poetry is the phenomenon of unstable correlation, which is a semiotic relationship between the plane of expression and the plane of content that appears as a process of production of reciprocal presupposition, which, in turn, is dependent on the focus point of reader’s gaze. In the first part of the article, in which I address theoretical considerations regarding all the above-mentioned topics, I examine how the model of structural linguistics can assist in complementing the semiotic analysis of visual poetry. In the second part, I analyze two works by contemporary Lithuanian visual poets using the proposed model of meaning creation: “PASTAZENKLAS ISLEISTAS KREPSINIO CEMPIJONATUJ” (“A POSTALSTAMP ISSUED FOR THE FOOTBALL CHEMPIONSHIP”) by Gytis Norvilas (2006) and “om rekonstrukcija I“ (“om reconstruction I”) by Donaldas Apanavičius from his three-poem cycle (1999). The analysis reveals the points of unstable correlation and various reading possibilities.

Published: February 2023

The classification and structuring of oxide and metallic phases of binary duplex systems of silicates-silicides of alkaline earth metals are carried out in the work. This will determine the optimal composition of alkaline earth metal alloys based on silicon in the refining of ferrocarbon melts and modification of non-metallic inclusions. The ionic-molecular complexes of magnesium, oxygen and silicon are constructed in the work, which determine the mechanism of formation of non-metallic inclusions (magnesium silicates) in steel when using silicomagnesium alloys for refining. The parameters of chemical bonding for oxides with ionic bond type, for liquid silicomagnesium alloys having a metallic type of chemical bonding and for hard alloys with metal-covalent bond are determined. The presented results of structural and chemical analysis of the duplex system MgO–SIO2–Mg–Si allow to reveal the mechanisms of desulfurization processes and to develop technologies of blast furnace desulfurization in smelting and ladle treatment with furnace slag, magnesium and its alloys with silicon.

Published: February 2023

The physical modeling method was used to study the processes of formation of the structure of sheet blanks during ingotless casting-rolling of metals. At the same time, on the basis of theoretical analysis, the main parameters are determined, with the help of which it is possible to effectively control the processes of crystallization and the formation of the structure of sheet blanks. The studies carried out made it possible to establish the regularities of the influence of hydrodynamic and thermophysical conditions of pouring metal (the speed and nature of metal movement in the inter-roll space, the overheating temperature of the melt and the intensity of heat removal from it) on the processes of its crystallization and structure formation. A transparent organic alloy camphene (C10H16) was used as a modeling medium, which makes it possible to visually study these processes during the ingotless rolling of metals. Due to the transparency of camphene, the transformation of the sheet blank structure at different stages of its formation was clearly studied: the rough primary structure of the crusts solidifying on the rolls, due to their partial deformation in the rolling zone, passes into a fine-grained structure upon exiting it. The dependence of the linear rate of metal pouring on the overheating temperature of the melt and the intensity of heat exchange processes in the roller mold is shown. At the same time, the optimal ranges of values of these parameters are determined, which ensure the stability of the process of roll casting of metals. The results obtained were the basis for the development of practical recommendations for roll casting of real metals, in particular aluminum alloys of various grades. Keywords: roll casting-rolling of metals, roll mold, melt hydrodynamics, overheating temperature, intensity of heat exchange processes, sheet blank, casting speed, structure transformation.
Modern ideas about the micronhomogeneous structure of metal melts (overview)
Authors:   Physico-Technological Institute of Metals and Alloys of the NAS of Ukraine, Verkhovliuk A. , Scheretsky O.
Published: February 2023

The review examines the question of modern ideas about the structure of metal melts in a wide temperature-concentration interval. The existing theories and models of their micro-inhomogeneous structure, namely quasi-chemical, cluster, and colloid, are presented. The quasi-chemical theory takes into account the arrangement of atoms in a metallic liquid, i.e., it is believed that the probability of atoms of the 1st and 2nd grade in one of the two neighboring places is different. It is based on comparing the probabilities of different ways of filling neighboring places. A cluster is a microgrouping of atoms that preserve a certain close-range order in their mutual arrangement and which are united by a general oscillatory movement of the entire grouping and at the same time half connected at any moment with the entire mass of matter in a given volume. Elements of disorder in this model of metal melts are introduced by the movement of activated atoms, thermal fluctuations, and diffusion displacements of clusters, which are associated with the movement of clusters, periodic formations and closing of intercluster gaps, and relaxation displacements of atoms in the middle of clusters, which are associated with thermal fluctuations. The colloidal model was formulated to explain the micro-heterogeneity of eutectic systems. According to this theory, the microheterogeneity observed after melting the sample is due to the long-term existence of microregions in the melt, which are a legacy of the chemically inhomogeneous initial casting, which is enriched with various components. These regions are considered as dispersed particles and the melt is considered as a microheterogeneous system consisting of dispersed and dispersed phases. The microheterogeneous state of the melt was distinguished by the presence of an interfacial surface that separates the inclusion from the main melt. The work also presents results that confirm the fact that amorphous alloys are structurally microinhomogeneous. Since these systems are formed at cooling rates of the initial melt of about 106 0C/s, their micro-heterogeneity is associated with the structure of liquid metal solutions. Keywords: micro-heterogeneity, metal melt, models, amorphous alloys.

OBJECTIVE

To identify potential differential changes in youth suicide deaths associated with the coronavirus disease (COVID-19) pandemic to better inform suicide prevention strategies.

METHODS

This cross-sectional study analyzed national suicide data for US youth aged 5 to 24 years from 2015 to 2020. Annual and monthly numbers of suicides were extracted overall and by sex, age, race and ethnicity, and method. Expected suicides were modeled from the trend in monthly deaths before COVID-19 (January 1, 2015–February 29, 2020), by using interrupted time-series analyses with quasi-Poisson regression. Rate ratios (RR) and corresponding 95% confidence intervals (CI) were used to compare expected and observed suicides during the first 10 months of COVID-19 (March 1, 2020–December 31, 2020).

RESULTS

Among 5568 identified youth suicides during the 2020 pandemic, 4408 (79.2%) were male, 1009 (18.1%) Hispanic, 170 (3.3%) non-Hispanic American Indian/Alaska Native, 262 (4.7%) Asian/Pacific Islander, 801 (14.4%) Black, and 3321 (59.6%) white. There was a significant increase in overall observed versus expected youth suicides during the COVID-19 pandemic (RR = 1.04, 95% CI = 1.01–1.07), equivalent to an estimated 212 excess deaths. Demographic subgroups including males (RR = 1.05, 95% CI = 1.02–1.08), youth aged 5 to 12 years (RR = 1.20, 95% CI = 1.03–1.41) and 18 to 24 years (RR =1.05, 95% CI = 1.02–1.08), non-Hispanic AI/AN youth (RR = 1.20, 95% CI = 1.03–1.39), Black youth (RR = 1.20, 95% CI = 1.12–1.29), and youth who died by firearms (RR = 1.14, 95% CI = 1.10–1.19) experienced significantly more suicides than expected.

CONCLUSIONS

Suicide deaths among US youth increased during COVID-19, with substantial variation by sex, age, race and ethnicity, and suicide method. Suicide prevention strategies must be tailored to better address disparities in youth suicide risk.
A study on computed tomography cardiothoracic ratio in predicting left ventricular systolic dysfunction
Authors: Chae Minki , Na Ji Ung , Lee Jang Hee , Shin Dong Hyuk
Published: February 2023

Objective A cardiothoracic ratio ≥0.50 is widely used as an indicator of cardiomegaly, but associations between the cardiothoracic ratio and left ventricular systolic dysfunction (LVSD) have not been investigated previously. We conducted this study to investigate the relationship between cardiothoracic ratio measured using computed tomography (CT) and left ventricular ejection fraction (LVEF), and to determine the optimal cardiothoracic ratio for predicting left ventricular systolic dysfunction (LVSD).Methods A retrospective cross-sectional study was performed using data from patients who underwent both chest CT and echocardiography at the emergency department from January 1 to December 31, 2021. The patients were classified as normal, or having mild, moderate, and severe LVSD based on their LVEF, and the cardiothoracic ratios of each group were compared. The receiver operating characteristic (ROC) curve analyses were used to identify the optimal cardiothoracic ratio for prediction of mild, moderate, and severe LVSD.Results The final study population included 444 patients. The median CT-measured cardiothoracic ratio was 0.54 for patients with normal LVEF, and 0.60 for patients with LVSD (P<0.001). The optimal CT-measured cardiothoracic ratios for predicting mild, moderate, and severe LVSD were 0.56, 0.59, and 0.60, and their areas under the ROC curve were 0.653, 0.690, and 0.680, and negative predictive values were 90%, 94%, and 98%, respectively.Conclusion The best cutoff value for a CT-measured cardiothoracic ratio suggestive of LVSD was 0.56, which is very different from the 0.50 value typically considered an abnormal cardiothoracic ratio. The CT-measured cardiothoracic ratio ≥0.56 can be used as a rough indicator of mild LVSD, and a ratio <0.60 can exclude severe LVSD with a high degree of confidence.

Published: February 2023

Application-specific systems with FPGA accelerators are often designed using high-level synthesis or hardware construction tools. Nowadays, there are many frameworks available, both open-source and commercial. In this work, we attempt to fairly compare several existing solutions (languages and tools), including Verilog (our baseline), Chisel, Bluespec SystemVerilog (Bluespec Compiler), DSLX (XLS), MaxJ (MaxCompiler), and C (Bambu and Vivado HLS). Our analysis has been carried out using a representative example of 8×8 inverse discrete cosine transform (IDCT), a widely used algorithm engaged in, among others, JPEG and MPEG decoders. The metrics under consideration include: (a) the degree of automation (how much less code is required compared to Verilog), (b) the controllability (possibility to achieve given design characteristics, namely a given ratio of the performance and area), and (c) the flexibility (ease of design modification to achieve certain characteristics). Rather than focusing on computational kernels only, we have developed AXI-Stream wrappers for the synthesized implementations, which allows adequately evaluating characteristics of the designs when they are used as parts of real computer systems. Our study shows clear examples of what impact specific optimizations (tool settings and source code modifications) have on the overall system performance and area. It emphasizes how important is to be able to control the balance between the communication interface utilization and the computational kernel performance and delivers clear guidelines for the next generation tools for designing FPGA accelerator based systems.
Overapproximation of the Number of Active Timers in Timed-Arc Petri Nets Using DP-Systems
Authors: Dworzanski Leonid Wladimirovich
Published: February 2023

Timed-arcs Petri nets are a time extension of Petri nets that allows assigning clocks to tokens. System of dynamic points on a metric graph (DP-systems) is another dynamical model that is studied in discrete geometry dynamics; DP-system combines continuous time and discrete branching events and used, for example, in study of localized Gaussian wave packets scattering on thin structures. In recent works, asymptotic estimates of the growth of the number of points in dynamic systems on metric graphs were obtained. In this paper, we provide a mean to overapproximate the number of different values of timers for a subclass of timed-arc Petri nets by constructing a system of dynamic points on a metric graph and prove overapproximation of the number of timer values by the number of points in the system of dynamic points.

This study was done to find out more about how a person talks. Conversations between two or more people are usually inseparable from mistakes, uncooperative actions and often exceed expectations. Therefore, an observation in an interview between Paris Lee and Emma Watson is intended to examine the flouting maxim in the speeches made. This research uses qualitative methods with Grice’s supporting theories cooperative principle and flouting maxim. Several data are included in the flouting maxim, namely four data flouting maxim of quantity, three data flouting maxim of quality, four data flouting maxim of manner, and two data flouting maxim relation. From the data analysis, it can be known that the flouting maxim arises when one of the participants, Watson and Paris, insert implied meaning into their speech until they were not cooperative during the interview. Keywords: flouting maxim, cooperative principle, utterance, conversation, interview
IBERIFIER Reports: The Impact of Disinformation on the Media Industry in Spain and Portugal
Authors: Moreno-Castro C. , Crespo M.
Published: February 2023

Disinformation, the deliberate spread of false or misleading information, has become an increasingly pressing issue in today’s society. The media industry, which plays a critical role in providing reliable and accurate information to the public, has been significantly impacted by the rise of disinformation. This IBERIFIER Report provides an analysis of the effects of disinformation on the media industry and the challenges it poses for journalists, media organizations, and the public. It highlights the erosion of public trust in the media, the need for journalists to verify information more rigorously, and the creation of a market for sensationalist and biased news. The researchers from IBERIFIER surveyed the Spanish and Portuguese population to analyze their response to disinformation and misinformation, their trust in media outlets, and their perception of media verification procedures. Data shows that both countries had high trust in health institutions, and both achieved high rates of complete vaccination among all population groups, especially the elderly and most vulnerable. Respondents from both countries trusted researchers, scientists, and experts the most, followed by journalists and doctors. However, respondents in Spain were skeptical about media paywalls and whether they prevented the dissemination of fake news. In Portugal, respondents showed a higher concern for disinformation in politics than among family members, colleagues, or friends. The survey analysis in Spain showed that gender influenced the loss of trust in media outlets that publish fake news, while the degree of trust in the media depended on the political party they voted for in the last elections. Media editors in both countries confirmed the importance of verification procedures, although there were differences in their approach. The report also suggests several solutions to combat disinformation, such as investing in media literacy programs, regulating online sources of disinformation, and promoting transparency and accuracy in reporting. By reading the report, policymakers, media organizations, and the general public can gain a better understanding of the effects of disinformation on the media industry in Spain and Portugal and the steps that can be taken to address this growing problem.
Exploring the association between teacher-related factors and Grade 9 mathematics achievement

Published: February 2023

Teacher well-being is an important issue that needs to be considered within a teaching environment. However, little research exists about the relationship between teacher well-being and learner performance. In this study we used data from the 2015 Trends in International Mathematics and Science Study (TIMSS) to look at the interplay between teacher-related factors (including stress), and the mathematics achievement of Grade 9 learners from South Africa in the 2015 TIMSS. The results show that levels of teacher stress, teacher qualification, class size, as well as the type of area in which the school is situated are all significantly associated with learner achievement. The findings of this study reveal that learners who are taught by teachers who feel more stressed, have large classes to contend with, are in schools located in poorer areas, and who are less qualified, are significantly more disadvantaged with regard to their mathematics education than their counterparts who are taught by teachers who do not share these problems. These findings suggest that it is important to consider the role of positive working environments for teachers in trying to find ways to improve the mathematics learning outcomes.
MODELING LAMINAR FLOW IN CONVERGING-DIVERGING CHANNELS
Authors: Fasogbon Samson Kolawole , Ayoade Adams Babatunde , Oyedepo Sunday Olayinka
Published: February 2023

Converging-diverging channels have been known to have low net charge (flow parameters) due to associated high frictional flow resistance. Thus, there is a need to optimize frictional flow resistance in these channels. To this end, frictional flow resistance was optimized for a laminar, fully formed flow in a linearly varying cross-sectional converging-diverging channel in this study. To achieve this, an empirical frictional flow resistance model was developed using continuity and momentum equations, and this accurately represents a parabolic axial velocity profile in converging-diverging section. The developed model was solved and parametric investigations carried out on geometrical and fluid flow parameters using MATLAB 6.1. The results show that the frictional flow resistance decreases as radius ratios increases, but increases as Reynolds number and taper angle increase. Radius ratios and Reynolds numbers were found to be more significant than taper angles. Results in comparison to available literature showed that the developed frictional flow model is an accurate model as it predicts axial velocity and the flow resistance with a high degree of precision. The study concludes that, for frictional flow resistance to be kept at barest minimum in a converging diverging channel, radius ratio must be maintained at its highest value and Reynolds number at its lowest possible value.
EFFECTS OF SURFACTANT ON LIFT COEFFICIENT OF ELLIPSOIDAL BUBBLES IN THE VISCOUS-FORCE DOMINANT REGIME
Authors: Chen Junming , Hayashi Kosuke , Legendre Dominique , Lucas Dirk , Tomiyama Akio
Published: February 2023

Effects of surfactants on lift coefficients, CL, of single ellipsoidal bubbles rising through linear shear flows were investigated. Two types of surface-active agents, Triton X-100 and 1-octanol, were used. The liquid properties except for the surface tension were identical to those in a clean system of logM = -5.5, where M is the Morton number. The range of the bubble Reynolds number was 0.1 < Re < 70. Bubble shapes were either spherical or ellipsoidal. Comparing with clean bubbles, less deformation of contaminated bubbles was confirmed. A shape correlation without taking the dimensionless shear rate into account gave good evaluations of the bubble aspect ratio, which means that the shear rate is not a dominant factor causing the change of shape deformation. However, drag coefficients were affected by the shear rate. A new correlation of drag coefficients was deduced, which agreed well with the experimental data. Both clean and contaminated CL data showed a similar tendency: after a drastic decrease in CL, CL slightly increases and then decreases to a negative value while increasing the bubble Reynolds number, Re. A difference in concentration of Trion X-100 resulted in only a slight change in CL at high Re regime. Different types of surfactant resulted in noticeably different values of CL especially at low Re. The CL of small bubbles in contaminated systems could be reproduced by a correlation for solid particles, supporting that fully contaminated spherical bubbles behave like solid spheres. For deformed bubbles, CL can be expressed by relating the negative lift force due to shape deformation with the drag force.

El impacto del ciclo menstrual en la fuerza muscular es un tema de interés para entrenadores y deportistas, del cual los estudios disponibles arrojan información escasa e incluso a veces contradictoria. Se recibieron respuestas de 30 mujeres eumenorreicas y no eumenorreicas de 21 a 55 años. El dolor menstrual (84%) y los síntomas premenstruales (93%) se informaron con frecuencia y contribuyeron a la fatiga y a las reducciones percibidas en el rendimiento durante las sesiones de entrenamiento. Según las mujeres de dicho estudio los síntomas premenstruales podrían afectar más a nivel psicológico que fisiológico, principalmente con respecto a la motivación para entrenar, y el estado de ánimo. El uso de anticonceptivos hormonales fue informado por el 40% de las participantes, las cuales manifestaron una disminución de sus síntomas premenstruales, así como también de la incidencia de dismenorrea y sangrando menstrual abundante. Como resultado, recomendamos que el ciclo menstrual se considere como una herramienta a tener en cuenta en la planificación del entrenamiento de forma individual.

Abstract This research is stressed at time and space characteristics (centre of gravity movements) in female pole vault. There are involved 19 female pole vault jumpers with sport performance 380 – 483 cm, divided on 2 different groups; higher and lower level from the point of sport performance. We found that in time parameters reached better results high performance level jumpers in phases hanging and lifting. It is coursed by better transmission on pole after take-off and by better work on the pole. As for the centre of gravity the jumpers of higher performance reached higher growth in all phases. The most significant difference can be seen in phase of lifting. Comparison of time and space characteristics enable to show the way for technique improvement in female pole-vault. Key words: female pole vault, rhythm of the jump, centre of gravity height
The Relationship of the Investigator and the Defense Attorney in the Process of Collecting Evidence
Authors:   Tomsk State University, Sviridov Mikhail K.
Published: February 2023

One of the manifestations of the adversarial principle is the legal definition of the investigator as the body of criminal prosecution. The investigator should be exempted from even the partial “two-facedness”, i.e. the investigator should collect only accusatory evidence and carry out other accusatory actions. In addition, it is necessary to determine the mechanism for collecting evidence by the defense attorney in the absence of the voluntary consent of the person (or organization) with evidentiary information to cooperate with the defense lawyer. If there is no such consent, then the defense attorney, as a subject of the defense function, must use the rights granted to him/her to collect independently the evidence necessary for the subsequent contest with the prosecutor in court. In the case when it is not possible to collect evidence due to the lack of consent of the persons in their presentation, the defense attorney should be given the right to seek assistance from the investigator.

The article discusses issues related to the functioning of an organized criminal community in the Soviet and modern Russian state. The process of criminalization of Russian society after the collapse of the USSR is traced. In order to weaken the criminal influence on law-abiding citizens, especially young people, it is very important to suppress the propaganda of the “romance” of a criminal lifestyle in the media. Modern Russian society needs works, television programs, and films that would show what colossal harm the criminal bosses and leaders of criminal groups and their followers inflict on the people; how, drawing into the orbit of their influence, they morally cripple adolescents and youth; the tragedy of a person who has bought on the “romance” of the underworld. Without significant support from the media, the efforts of law enforcement agencies in confronting the underworld will be useless. The initiative put forward by the president of the country will undoubtedly entail an intensification of the struggle against the leaders in the criminal hierarchy. However, it will hardly be possible to suppress organized crime with the help of criminal law measures alone. For these purposes, it is also necessary to widely use the experience of applying organizational and preventive measures used in different years in the fight against the criminal community.
Trials in the Court of First Instance in the Criminal Procedure of Lichtenstein: Comparative Features
Authors:   Higher School of Economics, Trefilov Aleksandr A.
Published: February 2023

Currently, there is not a single separate research work in Russian science on the topic of this article. In order to fill this gap, based on the normative and doctrinal sources, the author analyzes the consideration of the case on the merits in the criminal procedure of the Principality of Liechtenstein. In this legal order, in connection with the preservation of the institution of the investigating judge, one can only conditionally speak of bringing someone to trial since already at the stage of preliminary investigation cases are pending. The most important feature of the ordinary procedure for trying a case in the court of first instance is the principle of collegiality, by virtue of which, as a general rule, a case is tried by five judges. In addition, the developers of the 1988 Code of Criminal Procedure chose to abandon the use of lay judges. There are no plea deals in any form. Comparatively, it is interesting that the court has the right to recommend the convicted person for pardon, after which the head of state makes the final decision. The conclusions drawn can be useful to researchers who examine individual institutions of Russian and foreign criminal procedure.

One of the important tasks of the Penal Enforcement System is to maintain law and order. The analysis of departmental statistics has indicated a negative trend in the growth of illegal actions in correctional institutions, which greatly complicates the enforcement process. The reasons for the complication of penalty execution include general misunderstanding and ignoring the system of organising factors that determine latent and (or) open signs of a deteriorated state of law and order. There are a number of objective and subjective reasons for that, including insufficient terminology. To date, there is no legislatively defined or scientifically substantiated concept denoting the boundaries of the proper level of functionality of penal institutions. However, the employees of the penal institutions use the term “operational environment” in their everyday communication to describe the activities of a correctional institution subject to negative phenomena and processes. Moreover, there is no clear system of criteria for evaluating the activities of penal institutions, which makes it necessary to determine such criteria for the standard activity of penal institutions. For the most part, the assessment indicators are subjective and expressed by various ratings of functioning, which, in turn, makes it difficult to determine the framework for an ideal model of a correctional institution and the factors that affect its stable work as well as various deviations from the standard. It is necessary to substantiate the terminology to determine the content and general understanding of which features will characterise the stable operation of a correctional institution. There were attempts to define “operational environment” in various scholarly and practical works by researchers and employees on the penal system and internal affairs bodies of the Russian Federation. However, there is still no clear interpretation. Based on scholarly works and practical experience, the authors propose their own definition of “operational environment in correctional institutions”, which should be understood as a set of objective and subjective phenomena and processes in penitentiary institutions and beyond, affecting their stable operation.
On legal capacity and penal law enforcement actions of correctional institutions
Authors:   Samara Law Institute of the Federal Penitentiary Service of Russia, Useev Renat Z.
Published: February 2023

The issues of correctional institutions' legal capacity and penal law enforcement activities remain insufficiently studied in the science of penal law. Since correctional institutions are complex social organizations, the composition of subjects providing for the execution of sentences of imprisonment is not limited to correctional institutions. According to the author, taking into account generic and specific concepts, subjects that ensure the execution of custodial sentences should be classified into collective and individual. Penal law enforcement actions in correctional institutions' law enforcement activities are classified into three groups: (1) actions to establish the factual circumstances of the case; (2) actions expressing the choice and analysis of legal norms; (3) actions that ground the resolution of a legal case. Taking into account the implementation of regulatory and protective penal legal relations, the application of each of these groups of actions has its own features.
Recidivist criminals: Classification and typology
Authors:   East Siberia State University of Technology and Management, Filippova Olga V.
Published: February 2023

In criminology, data on persons who have committed a crime are generalised, and, based on it, classified and typologised. Classification of criminals involves their grouping on a single, individual basis; typology summarises the totality of social features typical of recidivist criminals. Based on the analysis of criminal record statistics, the article identifies the criteria for classifying recidivists and shows their distribution by groups, reviews typologies of recidivists and determines their bases. Recidivists' classification and typology allow systematising knowledge about their composition and determining the dynamics of their criminogenicity. Criminal statistics provide a number of classification criteria: statistical reporting forms contain data on the socio-demographic and criminal legal characteristics of convicts who had a criminal record at the time of the commission of a new crime. The typology of recidivists is based on the following criteria: the type of the crime, socio-psychological and pathopsychological features, reasons for a person's return to criminal activity, impact of the situation on recidivism. Recidivists are primarily criminogenic types since they repeatedly commit crimes. The most common is the mercenary type of recidivists: they commit thefts to solve financial problems in any suitable situation. The most common reasons for recidivism are the lack of a permanent job and alcohol abuse.

La maraca embrujada por jibaná, de Manuel Zapata Olivella: pre-textos y re-escritura
Authors: Valero Silvia
Published: February 2023

Este artículo analiza la presencia de pretextos en la novela inédita La maraca embrujada por jibaná, de Manuel Zapata Olivella. A través del concepto de “geografía de la imaginación” (Trouillot, 2011) argumento, por un lado, que las columnas aparecidas en El fígaro y Cromos sedimentan la base ideológica que se revela en la novela en términos de salud, exploraciones científicas y visión del Pacífico colombiano; y por otro, que algunos relatos de Pasión vagabunda (1947) fueron el punto de partida para la construcción narrativa de La maraca pero desde una perspectiva actualizada en función de los discursos sociales de los años 60.
