Du menaçant à l’irrésistible
Authors: Clouet Hadrien , Pillon Jean-Marie
Published: April 2024

L’invention d’un marché du travail, c’est-à-dire un espace où circulent les individus pour vendre leur force de travail à des employeurs, repose sur des infrastructures techniques mises en place par les gouvernements, permettant concrètement aux offreurs et aux demandeurs de se rencontrer et, éventuellement, de contractualiser. En France, différentes infrastructures ont coexisté et se sont succédé depuis deux cents ans, charriant chacune des représentations politiques spécifiques. À partir d’une enquête sociohistorique, ce texte propose une chronologie des régimes d’appariement publics sur le marché du travail français. Une fois surmontées les réticences du début du xixe siècle, les services de l’État centralisent les appariements à l’occasion de la Première Guerre mondiale, puis les planifient à la Libération, avant de développer des équipements de marché individualisant les trajectoires dans la période la plus récente. L’État s’impose donc progressivement comme un acteur économique, mais mobilise des catégories variables pour apparier l’offre et la demande : genre, profession et travailleurs coloniaux initialement, puis activité, qualification et production, avant d’aboutir à la séquence actuelle marquée par la compétence, le savoir et la mobilité. Ainsi, les discours sur la mobilité, la fluidité et la responsabilité individuelle s’appuient sur une intervention étatique croissante et de plus en plus détaillée pour décrire les postes et les travailleurs disponibles.
Using the Technology Acceptance Model for Factors Influencing Acceptance of Enterprise Resource Planning Solutions
Authors: Sternad Zabukovšek Simona , Bobek Samo
Published: April 2024

The technology acceptance of enterprise resource planning (ERP) solutions has become more and more important in the digital transformation of organizations. In contrast, ERP solutions used at an advanced level are necessary for other disruptive innovations. The chapter explains the technology acceptance of ERP solutions, starting with a description of frameworks/theories and a bibliometric analysis of publishing in this area. Technology acceptance of ERP solutions through the technology acceptance model (TAM) is analyzed in more detail, and findings regarding external factors influencing the acceptance of ERP solutions are discussed. Organizations of different sizes, from different sectors and with different ERP solutions may require custom-tailored research on ERP acceptance. Tailoring the approach based on the specific needs and characteristics of the organization can lead to better results.

Published: April 2024

Business schools worldwide are integrating sustainability into their curricula, yet a gap persists in understanding students' perspectives on these courses' effectiveness in preparing for sustainability challenges. This study investigates undergraduate students' perceptions of essential sustainability skills and knowledge they learn in a business school. Through three focus group interviews with 15 undergraduates, four themes emerged: mindsets, skills, learning approaches, and global perspectives. Students expect sustainability education to enhance comprehension, workforce readiness, and life skills, emphasising technical and global competencies. They advocate for more engaging, integrated online and face-to-face learning approaches to better prepare for sustainability careers.
EPSSNet

Published: April 2024

Fast and accurate segmentation is important for robot judgement, e.g. robot detection, segmentation, and control. Most researchers have focused on deploying lightweight semantic segmentation models into robot services. The problem is that the critical interaction between semantic segmentation and boundaries is ignored. In this chapter, the authors propose a lightweight parallel execution model (EPSSNet) based on semantic flow branch (SFB), edge flow branch (EFB) and self-adapting weighting fusion (SAWF) for mobile robot service projects. The semantic flow branching module is used to obtain accurate object shape features. The boundary constraint module uses multiple convolution and upsampling to distinguish boundary features from semantic features. In order to adaptively fuse boundary features with semantic segmentation features, the SAWF is proposed. It adaptively fuses semantic and boundary features by learning boundary and semantic feature fusion weights. Detailed experimental results on Cityscapes, Pascal VOC 2012 and ADE20k datasets demonstrate the superior performance of our approach.
Measurement and Policy Optimization of Regional Preschool Education Development Level Based on Generalized Orthogonal Fuzzy Sets and Prospect Theory
Authors: Wang Qian
Published: April 2024

Preschool education belongs to non-compulsory enlightenment education, and it is difficult to measure and analyze the development of preschool education in different regions because of its multiple attributes and diversity of influencing factors. In addition, decision makers will be limited by their own cognition when facing multi-attribute factors and uncertain factors, and there is a big gap between the decision results given and the actual situation. Therefore, this chapter introduces generalized orthogonal fuzzy sets and prospect theory into the measurement model of preschool education development level based on technique for order of preference by similarity to ideal solution (TOPSIS) method to improve the decision accuracy of decision makers. The experimental results show that the model can effectively deal with uncertain information and improve the analysis accuracy, and the results are more in line with the actual situation than other models. At the same time, it can intuitively compare and analyze the development of preschool education in different regions, and provide reliable data support for decision makers.

YouTube, the Internet and IACCP: Opportunities and Challenges for Cross-Cultural Psychology
Authors: Gabrenya William , van Meurs Nathalie , Fischer Ronald
Published: April 2024

We culturalists are an unusual lot! Dispersed geographically and divided socially by potential and real political conflict, economic competition, religious disagreement and vast disparities in wealth and resources, we struggle with the dilemma of studying diversities that can only be understood adequately through effective communication and collaboration. The International Association for Cross-Cultural Psychology was conceptualized by psychologists who recognized and participated in this dialectical context. The Founders set out to create an organization that would provide communication venues in order to facilitate the development of a community of psychologists who would collaborate on cultural research. Communication, indeed, was the starting point of IACCP, in face-to-face interactions at international conferences in the 1960s and through a project begun in 1969 by Harry Triandis, the Cross-Cultural Social Psychology Newsletter. These two types of communication were precursors to the founding of the Association in Hong Kong in 1972.
Subcultural Influences on Self-attitudes: The Expression of Low Self-esteem in Race/ethnicity-, Age-, Gender-, Social class-, and Generation-differentiated Subgroups
Authors: Kaplan Howard , Kaplan Rachel , Kaplan Diane
Published: April 2024

Self-esteem is conceptualized in terms of self-feelings that are evoked by self-evaluation of self-concept and that motivate self-enhancing or self-protective responses. Since (sub)cultural conventions and the self-esteem motive frequently invalidate self-report measures, it is argued that self-esteem should be measured as the confluence of self-evaluative statements and measures of subjective distress. In support of this, findings are presented from a longitudinal multigeneration study that demonstrate variation in the association between self-evaluative statements and reports of emotional distress between groups differentiated according to race/ethnicity, age, gender, social class, and generation. The results clearly indicate that prevalent self-report measures, whether considering total scores or component items, have differential emotional significance depending on groupings.
Effects of Reading Direction on Visuospatial Organization: A Critical Review
Authors: Chokron Sylvie , Kazandjian Seta , De Agostini Maria
Published: April 2024

Over the past decades, a growing literature on perceptual bias has investigated the factors that determine normal performance in simple visuospatial tasks, such as line bisection and aesthetic preference. Normal right-handed participants may exhibit spatial asymmetries in these tasks with a tendency to bisect to the left of the objective middle in line bisection and a preference for images with the center of interest in their right half in aesthetic preference tasks. These patterns of performance have mostly been attributed to hemispheric imbalance. Other explanations have also been put forth to explain the spatial asymmetries seen in the normal population. Here we review studies that target the role of reading direction on visuospatial tasks. In addition to presenting several of our studies that investigated differences in line bisection and aesthetic preference performances between left-to-right readers (French) and right-to-left readers (Israeli), we present a discussion of the existing literature on reading direction, culture and visuospatial processing. The findings are discussed regarding the interaction between cultural factors, such as reading habits, and biological factors, such as cerebral lateralization, in visual perception.
Causes of Culture: National Differences in Cultural Embeddedness
Authors: Schwartz Shalom
Published: April 2024

What causes national differences in culture? Past attempts to answer this question take insufficient account of how slowly culture changes or of the fact that culture itself influences the social structural, political, and demographic variables identified as causes. Convincing causes of cultural differences must meet three criteria: They should reflect the formative historical experiences of societies, they should not be influenced reciprocally by culture, and theoretically plausible process should explain their impact on culture. I propose and explain causes of national differences in cultural embeddedness, a value orientation that calls upon people to find meaning in life through identifying with their in-group, participating in its shared way of life, and striving toward its shared goals. Analyses of data from 77 cultural groups (74 countries) demonstrate that cultural embeddedness is greater in ethnically heterogeneous societies, with a relatively short history of viable state institutions, whose historically dominant religion was Islam rather than Protestantism or Roman Catholicism. These causal findings are not due to diffusion of culture to nearby countries or colonies. They hold up even when predicting differences in cultural embeddedness among eight world regions or within Eastern and within Western Europe. This research can be a model for investigating causes of various cultural differences among nations and other groups.
From Homer to the 21st Century: Charting the Emergence of the Structure of Interpersonal Meaning
Authors: Adamopoulos John
Published: April 2024

During the last quarter of the 20th century, cross-cultural research established that the meaning of interpersonal behavior can be described in terms of a universal structure that includes, among others, the notions of association (affiliation), superordination (dominance), and intimacy. While researchers generally agree on most of these universal dimensions, little is known about their origins –the whys and the wherefores of these structures. An approach designed to explain the emergence of the meaning of interpersonal behavior is the focus of this chapter. This approach is based on the assumption that social behavior involves the exchange of material and psychological resources, a process guided by a number of natural constraints operating on human interaction. The chapter outlines this theoretical system and discusses the emergence of the primary features of meaning over long periods of time. It reviews formal analyses of information gleaned from literary documents of different historical periods and cultures, including the works of Homer, Hesiod, and Theophrastus, as well as other sources (e.g., medieval European literature). It concludes with a discussion of how this approach can account for various social-psychological phenomena and can lead to the development of a useful theory of culture for psychology.
An Examination of Acquiescent Response Styles in Cross-Cultural Research
Authors: Fischer Ronald , Fontaine Johnny , van de Vijver Fons , van Hemert Dianne
Published: April 2024

Response styles constitute a formidable challenge for cross-cultural research. In this article, three different response styles are discussed (acquiescence, extremity scoring, and social desirability). Acquiescence responding (ARS) is then integrated into a larger classical test theoretical framework, which allows for an examination of the various roles that ARS may play in cross-cultural research. A new meta-analytical method is proposed to examine the prevalence and nature of ARS. Preliminary evidence suggests that ARS has only a small, but systematic effect on survey responses. The meaning of ARS is explored through correlations with nation-level indicators. Implications for future research are discussed.
Glucagon-Like Peptide-1: New Regulator in Lipid Metabolism
Authors: Bu Tong , Sun Ziyan , Pan Yi , Deng Xia , Yuan Guoyue
Published: April 2024

Glucagon-like peptide-1 (GLP-1) is a 30-amino acid peptide hormone that is mainly expressed in the intestine and hypothalamus. In recent years, basic and clinical studies have shown that GLP-1 is closely related to lipid metabolism, and it can participate in lipid metabolism by inhibiting fat synthesis, promoting fat differentiation, enhancing cholesterol metabolism, and promoting adipose browning. GLP-1 plays a key role in the occurrence and development of metabolic diseases such as obesity, nonalcoholic fatty liver disease, and atherosclerosis by regulating lipid metabolism. It is expected to become a new target for the treatment of metabolic disorders. The effects of GLP-1 and dual agonists on lipid metabolism also provide a more complete treatment plan for metabolic diseases. This article reviews the recent research progress of GLP-1 in lipid metabolism.

Published: April 2024

INTRODUCTION: Annual influenza epidemics and rare pandemics represent a significant global health risk. Since the upper respiratory tract is the primary target of influenza, a diagnosis of influenza illness might be made using deep learning applied to pictures of the pharynx. Using pharyngeal imaging data and clinical information, the researcher created a deep-learning model for influenza diagnosis. People who sought medical attention for flu-like symptoms were the subjects included.
METHODOLOGY: The study created a diagnostic and predicting Artificial Intelligence (AI) method using deep learning techniques to forecast clinical data and pharyngeal pictures for PCR confirmation of influenza. The accuracy of the AI method as a diagnostic tool was measured during the validation process. The extra research evaluated the AI model's diagnosis accuracy to that of three human doctors and explained the methodology using high-impact heat maps. In the training stage, a cohort of 8,000 patients was recruited from 70 hospitals. Subsequently, a subset of 700 patients, including 300 individuals with PCR-confirmed influenza, was selected from 15 hospitals during the validation stage.
RESULTS: The AI model exhibited an operating receiver curve with an area of 1.01, surpassing the performance of three doctors by achieving a sensitivity of 80% and a specificity of 80%. The significance of heat maps lies in their ability to provide valuable insights. In AI models, particular attention is often directed towards analyzing follicles on the posterior pharynx wall. Researchers introduced a novel artificial intelligence model that can assist medical professionals in swiftly diagnosing influenza based on pharyngeal images.

Published: April 2024

INTRODUCTION: A deep learning model may be used to predict the occurrence of diabetic foot infections and to understand how these infections spread over time by using sophisticated machine learning methods. Untreated diabetic foot infections, a common diabetic complication, may have devastating effects.
METHODOLOGY: One area where deep learning models—a kind of machine learning—shine is in healthcare, where they are well-suited to deal with data that contains intricate patterns and correlations. The metabolic illness of diabetes affects more individuals than any other.  Neuropathic and Ischemic ulcers are two types of foot ulcers that these issues may cause. Damage to the nerves and blood vessels is the primary cause of this ulcer. Numerous amputations and fatalities have resulted from these sores. There are millions of victims of this illness throughout the globe. The amputation of a human leg occurs once every 30 seconds. The precise anticipation of diabetic foot ulcers has the potential to significantly alleviate the substantial impact of amputation Therefore, it is crucial to correctly categorize foot ulcers and discover them as soon as possible for more effective treatment.
RESULTS: An extensive literature review of classification methods, including decision trees, random forests, the M5 tree method, Random trees, neural network models, ZeroR, Naive Bayes, the Back Propagation Neural Network, Linear Regression model, and Deep Learning Algorithms is presented in this research with a primary emphasis on foot ulcer classification. Using the Kaggle dataset, these algorithms are ranked. In the end, it presents a comparison of different classifiers.

In Uganda, women engaged in sex work (WESW) are a marginalized population at the intersection of multiple vulnerabilities. The Kyaterekera intervention is targeted at WESW in Rakai and the greater Masaka regions in Uganda and combines a traditional HIV risk-reduction approach with a savings-led economic empowerment intervention and financial literacy training. We estimated the economic costs of the Kyaterekera intervention from a program provider perspective using a prospective activity-based micro-costing method. All program activities and resource uses were measured and valued across the control arm receiving a traditional HIV risk-reduction intervention and the treatment arm receiving a matched individual development savings account and financial literacy training on top of HIV risk reduction. The total per-participant cost by arm was adjusted for inflation and discounted at an annual rate of 3% and presented in 2019 US dollars. The total per-participant costs of the control and intervention arms were estimated at $323 and $1,435, respectively, using the per-protocol sample. When calculated based on the intent-to-treat sample, the per-participant costs were reduced to $183 and $588, respectively. The key cost drivers were the capital invested in individual development accounts and personnel and transportation costs for program operations, linked to WESW’s higher mobility and the dispersed pattern of hot spot locations. The findings provide evidence of the economic costs of implementing a targeted intervention for this marginalized population in resource-constrained settings and shed light on the scale of potential investment needed to better achieve the health equity goal of HIV prevention strategies.
Potential Impact of a Diagnostic Test for Detecting Prepatent Guinea Worm Infections in Dogs
Authors: Smalley Hannah , Keskinocak Pinar , Swann Julie , Hanna Christopher , Weiss Adam
Published: April 2024

Chad has seen a considerable reduction in cases of Guinea worm disease (or dracunculiasis) in domestic dogs in recent years. Tethering of dogs and application of Abate® larvicide to water sources appear to have contributed to this progress, but with 767 reported dog cases in 2021, accelerating elimination of the disease in Chad may require additional tools. We investigate the potential benefits of a hypothetical diagnostic test that could be capable of detecting prepatent infections in dogs. We adapt an agent-based simulation model for forecasting the impact of interventions on guinea worm disease in dogs to examine the interaction of multiple test factors including test accuracy, when the test can detect infection, dog selection, and dog-owner compliance with tethering recommendations. We find that a diagnostic test could be successful if used in conjunction with existing interventions, and elimination can be achieved within 2 years with 80% or higher test sensitivity, 90% or higher specificity, systematic testing of each dog twice per year, and more than 90% long-term tethering compliance when a dog tests positive or a worm is emerging. Because of the long incubation period of Guinea worm disease (10–14 months) and the fact that no treatment exists, the benefits of the test rely on the testing rollout and response of dog owners. If the test could estimate the timing of worm emergence, long-term tethering could be eliminated and infected dogs could be tethered only when the worms are expected, minimizing the related resources (human and financial) to support the intervention.

Published: April 2024

Dengue fever (DF) is an endemic infectious tropical disease and is rapidly becoming a global problem. Dengue fever is caused by one of the four dengue virus (DENV) serotypes and is spread by the female Aedes mosquito. Clinical manifestations of DF may range from asymptomatic to life-threatening severe illness with conditions of hemorrhagic fever and shock. Early and precise diagnosis is vital to avoid mortality from DF. A different approach is required to combat DF because of the challenges with the vaccines currently available, which are nonspecific; each is capable of causing cross-reaction and disease-enhancing antibody responses against the residual serotypes. MicroRNAs (miRNAs) are known to be implicated in DENV infection and are postulated to be involved in most of the host responses. Thus, they might be a suitable target for new strategies against the disease. The involvement of miRNAs in cellular activities and pathways during viral infections has been explored under numerous conditions. Interestingly, miRNAs have also been shown to be involved in viral replication. In this review, we summarize the role of known miRNAs, specifically the role of miRNA Let-7c (miR-Let-7c), miR-133a, miR-30e, and miR-146a, in the regulation of DENV replication and their possible effects on the initial immune reaction.

Surveillance for genetic markers of resistance can provide valuable information on the likely efficacy of antimalarials but needs to be targeted to ensure optimal use of resources. We conducted a systematic search and review of publications in seven databases to compile resistance marker data from studies in India. The sample collection from the studies identified from this search was conducted between 1994 and 2020, and these studies were published between 1994 and 2022. In all, Plasmodium falciparum Kelch13 (PfK13), P. falciparum dihydropteroate synthase, and P. falciparum dihydrofolate reductase (PfDHPS) genotype data from 2,953, 4,148, and 4,222 blood samples from patients with laboratory-confirmed malaria, respectively, were extracted from these publications and uploaded onto the WorldWide Antimalarial Resistance Network molecular surveyors. These data were fed into hierarchical geostatistical models to produce maps with a predicted prevalence of the PfK13 and PfDHPS markers, and of the associated uncertainty. Zones with a predicted PfDHPS 540E prevalence of >15% were identified in central, eastern, and northeastern India. The predicted prevalence of PfK13 mutants was nonzero at only a few locations, but were within or adjacent to the zones with >15% prevalence of PfDHPS 540E. There may be a greater probability of artesunate–sulfadoxine–pyrimethamine failures in these regions, but these predictions need confirmation. This work can be applied in India and elsewhere to help identify the treatments most likely to be effective for malaria elimination.

Tunability Dependence of All-Optical Liquid Crystal Delay Line on Laser Polarization and Incidence Angle
Authors: Li Jinfeng
Published: April 2024

This work experimentally investigates the optical manipulation of trans-cis swaps and resultantly their optical/electromagnetic imprints as a driver for realizing the tunable delay lines in the microwave X band (8-12 GHz) regime utilizing the polarization and incident angle dependencies of azo-admixed liquid crystals (LCs). Measurement results confirm that the tuning efficacy of the azo-LCs-based delay line is highly dependent on the polarization of the laser beam concerning the rubbing and filling directions of LCs. When the laser light beam is polarized parallel to the rubbed direction as well as the LCs filling direction, the achievable differential phase shift is maximized. Full Text: PDF References

Antioxidant and protective activities of aqueous Theobroma cacao seed extract against aluminium-induced hippocampal toxicity in Wistar rats
Authors: Okhah Anita A. , Enogieru Adaze B.
Published: April 2024

Aluminium (Al) is a known toxic metal linked to oxidative damage and neurodegeneration. Hence, the antioxidant and neuroprotective effects of aqueous Theobroma cacao seed extract (CO) in aluminium chloride-exposed Wistar rats was examined. The study consisted of six (6) groups containing six (6) Wistar rats each. Group A (Control) received 1 ml of distilled water/day. Group B (Al) received 100 mg/kg body weight (BW) of Al only. Group C received 250 mg/kg BW/day of CO and 100 mg/kg BW of Al. Group D received 500 mg/kg BW of CO and 100 mg/kg BW of Al. Group E received 250 mg/kg BW of CO only. Group F received 500 mg/kg BW of CO only. The administration was via an orogastric tube for 28 days after which the Novel Object Recognition (NOR) neurobehavioral test was conducted. Thereafter, the rats were sacrificed and the hippocampi were harvested for antioxidant and histological evaluations. A significant decrease in the antioxidant enzymes activities, final body weight and neurobehavioural functions were observed in the rats treated with Al only following comparison with the control and CO-treated groups. However, CO protected against these Al-induced effects. Also, several histological alterations were observed in the Al groups, whereas control and CO-treated groups were relatively normal. Taken together, CO had potent antioxidant and protective activities against Al-induced toxicity in the experimental rats.

Authors: Yang Zhangrui , Long Yizhou , Yang Xiaoben , Liu Jinfeng , Zhu Guocheng
Published: April 2024

Coagulation, a fundamental and crucial operation in water treatment, has a long history of application in water/wastewater treatment processes. The efficiency of coagulation depends primarily on the quality, type, and quantity of coagulants used. Although aluminum or iron-based coagulants are the most commonly employed, polymeric silicate coagulants (PSCs) are less frequently utilized. However, the PSCs are promising candidates that deserve further exploration and examination of their potential applications. This review presents an examination of the advantages, synthesis theory, coagulation mechanism, and structure of PSCs. It also delves into the current limitations of these coagulants in research and the challenges that lie ahead for future studies. Finally, it offers some suggestions for future research directions. These discussions are intended to aid readers in comprehending the fundamental characteristics of these coagulants, enabling them to grasp their design methodologies and application area. This understanding can contribute to overcoming the limitations of this type of flocculants, further enhancing their effectiveness.
Comparative study for adsorptive removal of radioactive Cs+, Sr2+ and Co2+ ions from aqueous solution by acid-activated white clay
Authors: Kim Daeik , Hwang Sun-Jin , Bae Su Ho , Ryoo Keon Sang
Published: April 2024

Raw white clay was acidified with H2SO4 (2 M) and then activated in a furnace for 2 h at 150oC. The resulting acid-activated clay product was used as an adsorbent for the removal of radioactive substances such as Cs+, Sr2+ and Co2+ ions in aqueous solution. The specific surface area and the pore volume of acid-activated clay were three times higher compared to raw white clay. At 100 mg L- of initial concentration and 1.0 g of dosage, removal efficiencies of Cs+, Sr2+ and Co2+ ions showed 60.0%, 27.3%, and 88.1%, respectively. It was found that the Langmuir isotherm was described well to the adsorption behavior of Cs+, Sr2+ and Co2+ ions on acid-activated clay rather than Freundlich isotherm. The Langmuir isotherm constant (Q) for Cs+, Sr2+ and Co2+ ions was found to be 8.81, 3.78 and 10.20 mg g-1, respectively. Compared to the pseudo-first-order kinetic model, the pseudo-second-order kinetic model was more suitable for adsorption of Cs+, Sr2+ and Co2+ ions in water/acid-activated clay medium owing to the higher correlation coefficient (R2) and the more proximity value of the experimental value qe,exp and the calculated value qe,cal.

Цель: проанализировать существующие в юридической науке подходы к определению общего объекта преступления как правового блага, то есть аксиологические аспекты общего объекта преступления. Методы: диалектический, позволивший уточнить понятия «конституционная ценность», «общий объект преступления»; сравнительно-правовой, использовавшийся для сравнения понятий «конституционная ценность», «общий объект преступления». Результаты: исследования конституционных ценностей направлены в основном на обоснование их фундаментального значения и решение теоретических проблем воплощения конституционных ценностей в форме норм-принципов, норм-целей и т. д. Конституционные ценности являются основой для определения общего объекта преступления как правовой ценности. Рассмотрение общего объекта преступления с ценностных позиций позволяет установить, какие цен- ности, интересы или правовые блага признаются обществом настолько значимыми, что их нарушение является преступлением. Выводы: категория «общий объект преступления» охватывает индивида, пострадавшего от преступного деяния, и его правовые интересы, такие как жизнь, здоровье, собственность. Положения Уголовного кодекса Российской Федерации в целом отражают ценностный подход к определению общего объекта преступления.

Introduction: the article considers a problem of constitutional values that form the basis for axi- ological understanding of a general object of crime and a category “general object of crime” from a value standpoint. Purpose: to analyze current approaches to the definition of the general object of crime as a legal good, i.e. axiological aspects of the general object of crime. Methods: a dialectical method is used to clarify concepts “constitutional value” and “general object of crime”; a compara- tive legal method – to compare the concepts discussed. Results: current scientific works are aimed mainly at substantiating their fundamental importance and solving theoretical problems of embody- ing constitutional values in the form of norms-principles, norms-goals, etc. Constitutional values are the basis for defining the general object of crime as a legal value. Considering the general object of crime from a value standpoint allows us to determine which values, interests or legal benefits are recognized by society as so significant that their violation is a crime. Conclusion: the category “gen- eral object of crime” covers an individual who has suffered from a criminal act and his legal interests, such as life, health, property. Provisions of the Criminal Code of the Russian Federation, in general, reflect a value-based approach to determining the general object of crime.
