Hybrid Image Filtering Method Based on Wavelet Transform
Authors: Moindop Marlise Nguessotat , Yenke Blaise Omer
Published: August 2024

The image acquisition process often ends with obtaining an image tainted with parasitic information which alters its quality. In order to analyze the image effectively and thus make reliable decisions, it is essential to reduce or even eliminate the noise that corrupts it. This work proposes a method of filtering images in order to reduce the noise they contain. The proposed method is a combination of bilateral filter, bivariate shrinkage and Bayes Shrink thresholding in the wavelet domain. This method consists of applying the bilateral filter to the noisy image and then decomposing it into eight wavelet sub-bands. Subsequently, bivariate shrinkage is applied to the first-level detail sub-bands, and BayesShrink thresholding is applied to the second-level detail sub-bands. The filtered image is obtained after wavelet reconstruction. The experiments were carried out on two most used images in the literature (Cameraman and Lena) corrupted with Gaussian with noise variance σ2 N = {0.05, 10, 20, 30, 50}. The performance of the proposed method was evaluated in terms of PSNR. The results obtained compared to certain approaches in the literature show that the proposed method is efficient and considerably outperforms those of existing works with an optimal PSNR value.

Published: August 2024

The farmers of the Buea municipality, Fako Division, South-West Region, Cameroon extensively use Abamectin or Aba, a phytosanitary insecticide which targets insects such as mites, thrips species and leaf miners. In this area, the local population also uses Dicliptera laxata traditionally as a fertility enhancer and in stabilizing risky pregnancies in women. This study was aimed at evaluating the actions of Dicliptera laxata aqueous extract on the estrous cycle and reproductive system of Aba-treated female rats. A total of 30 adult female rats of the confirmed regular cycle were daily treated orally with a 2 ml/kg Abamectin for a period of 45 days, accompanied by the evaluation of the cytology of their vaginal smears at 5 days intervals. From the 46th day, they were subsequently treated with the leaf-aqueous extract of Dicliptera laxata for 15 days and were terminated on the 61st day during which blood and reproductive organs were collected for biochemical assays and relative weight indices. Chronic (45 days) exposure of normal cycled female rats to Abamectin witnessed a blockade in their estrous cycle, a significant drop in plasma estradiol and progesterone concentration, and a significant drop in the percentage weight of organs. Administration of Dicliptera laxata leaf-aqueous extract to these Aba-treated females resulted in a return to the regularity of their estrous cycle, with animals receiving the 300 mg/kg dose of plant extract recording a 60% regulation in the first week and 100% in the second week as compared to animals treated with distilled water that recorded a 0% and 20% regulation in the first and second week of treatment, respectively. Also, the animals that received 300 mg/kg body weight of the extract registered significant (p < 0.05) rise in plasma concentrations of progesterone and estradiol (36.44 ± 1.69 pg/mL and 77.73 ± 3.82 pg/mL, respectively) as compared to animals that received distilled water which showed 22.54 ± 2.19 pg/mL plasma progesterone and a 44.90 ± 7.63 pg/mL plasma estradiol concentrations, respectively. The actions of the leaf-aqueous extract of D. laxata could be attributed to the presence of phytochemicals including steroids, phenolic compounds, alkaloids and saponins in our extract, which have been reported to have important pharmacological effects on female reproduction. D. laxata, therefore, constitutes a potential treatment of female infertility and our findings justify its folkoric use by the Bakweri tribe in enhancing fertility. It can be used to stalize risky pregnancies and prevent miscarriages.

Published: August 2024

OBJECTIVE

To determine if sedation with medetomidine-vatinoxan (Zenalpha; Dechra Veterinary Products) and midazolam (Alvogen) (ZM) would cause less cardiovascular depression and maintain similar depth and duration of sedation in pigeons (Columba livia domestica) compared to dexmedetomidine and midazolam (DM).

METHODS

In a blinded crossover study, 15 healthy adult domestic pigeons were sedated IM with either dexmedetomidine (0.08 mg/kg) and midazolam (2 mg/kg) or medetomidine (0.16 mg/kg), vatinoxan (3.2 mg/kg), and midazolam (2 mg/kg) from November through December 2023. Each subject was monitored for 60 minutes, then the sedation was reversed with atipamezole (0.8 mg/kg) and flumazenil (0.1 mg/kg) as needed. Sedation scores, heart rates, and respiratory rates were compared.

RESULTS

There was no significant difference in the peak sedation score between DM and ZM groups, with both exhibiting median scores of 4 (heavy sedation). Mean heart rate was significantly higher for ZM than DM at 5, 10, 20, 30, 45, 60, and 65 minutes postinjection. Bradycardia occurred in both groups at 5 and 10 minutes postinjection and persisted for DM until reversal with atipamezole. Arrhythmias were auscultated in both groups. Bradypnea was not observed in either group, and all birds resumed normal behavior following recovery and the following day.

CONCLUSIONS

Medetomidine-vatinoxan-midazolam provides a similar depth of sedation to DM but with less incidence of bradycardia. Further study is needed to determine the clinical applicability of this sedative in birds.

CLINICAL RELEVANCE

Medetomidine-vatinoxan may be considered for short-term sedation and restraint in cardiovascularly stable pigeons.

Published: August 2024

Social network data mining (SNDM) technology shows great application potential in crime analysis and prevention. This study focuses on revealing the characteristics, laws, and trends of criminal behavior through an in-depth analysis of criminal information in social networks. Using data mining techniques such as association rule mining, cluster analysis, and community discovery, the key information and organizational structure of criminal networks are successfully mined, which provides a powerful means of investigation and prevention for public security departments. It is found that important criminal clues are hidden in the user communication data in social networks, and the communication mode and hidden information between criminals can be revealed through association rule mining technology. Cluster analysis helps to identify gangs and hot spots with similar criminal behaviors, which provides important clues for further investigation. In addition, community discovery technology further reveals the internal structure and membership relationship of criminal gangs, which is helpful in deeply understanding the operation mode of criminal organizations and the spread path of criminal acts. Based on historical data and mining results, this study also constructs a crime trend prediction model, which provides timely early warning information for public security departments and helps to take measures to prevent and crack down on criminal acts in advance. On the whole, this study not only enriches the application theory of SNDM technology in the field of crime analysis but also provides new ideas and tools for actual crime investigation and prevention.

Published: August 2024

With the popularization of digital transformer substations, it is of great research significance to study the upgrade of electronic transformer calibration devices, especially in the scene of small signals and high precision. In this paper, a compensation correction method is proposed to obtain more accurate primary side current parameters of the tuning device. By establishing the J-A magnetic characteristic model of the CT, the relationship between the magnetic characteristics of the CT and the corresponding terminal voltage is analyzed, and the relationship model between the terminal voltage and the corresponding excitation current is established. The model is used as the correction value in the feedback loop of the current measurement of the integral inspection device, to obtain the accurate primary side current. This method is applied to an electronic transformer calibrator inspection device system based on the Beidou system, which improves the data measurement accuracy of the device sensor and ensures that the measurement data accuracy reaches 0.1S.

Authors: Nguyen Philip Phu-Tan , Meade Maurice J. , Jamieson Lisa M. , Haag Dandara G.
Published: August 2024

Objective

This study aimed to describe orthodontic treatment patterns of children in Australia.

Methods

Using data from the 2012-2014 National Child Oral Health Study (NCOHS), a cross-sectional survey representative of children in Australia aged 5 to 14 years involving parental-completed questionnaires, standardised oral examinations and malocclusion severity assessment, the present study examined: sociodemographic characteristics, types and providers of orthodontic treatment, extraction rates, treatment need levels and orthodontic service access.

Results

Adolescents (31.7%), children from higher-income households (22.0%), and those with handicapping malocclusions (46.6%) accessed services more than their counterparts. Of those who had ever accessed services, pre-adolescents mostly had a consultation only (46.5%) and were predominantly treated using removable appliances (25.1%). Adolescents mostly had fixed appliances (38.0%). Extractions were involved in 31.0% of fixed appliance treatments. Private orthodontists provided the majority of treatment services (80.6%). There were greater numbers of higher-severity malocclusions affecting males, indigenous children, and children from lower-income households compared with their counterparts. In those with higher-severity malocclusions, males, children with high-school-only-educated parents, and children from lower-income households accessed services less than their counterparts.

Conclusions

The present study provides baseline information for Australian orthodontic services. Disparities in malocclusion severity and service access were noted. Increased malocclusion severity did not necessarily increase the likelihood of accessing services.
The Eu Project of the ‘Aml Package’ – Reform or Revolution in The Field of Counteracting of Money Laundering
Authors: Golonka Anna
Published: August 2024

The study is an original scientific article devoted to the issues of proposed changes in the EU regulations on counteracting money laundering (the so-called ‘AML package’). A significant part of the amended provisions of EU legal acts will be governed by EU Regulations and, as such, they will be directly applicable. This situation justifies the need for an in-depth analysis. On the other hand, those provisions which remain in the form of directives raise certain reservations. Therefore, the aim of this article is to analyse the nature and scope of the comprehensive amendment to the AML regulations using a formal-dogmatic method. Based on this analysis, conclusions were drawn regarding the assessment of the legitimacy and possible effectiveness of the proposed regulations in combating money laundering. The conclusion also highlights the inaccuracies and deficiencies they are burdened with, allowing for de lege ferenda postulates concerning the desired correction of the regulations.

Published: August 2024

The subject of this article is the introduction of cybersecurity-related regulations on the providers of infrastructure for the provision of 5G technology services into the Polish legal system. In particular, the implementation of the recommendations of the report prepared by the Network and Information System Cooperation Group entitled Cybersecurity of 5G networks EU Toolbox of risk mitigating measures (referred to as the 5G Toolbox). Following the recommendations of the European Commission, Poland has undertaken work on introducing regulations that would implement the provisions of the 5G Toolbox regarding high-risk suppliers. An amendment to the Act on the National Cybersecurity System of 3 July 2023 (‘the Bill’) has been prepared, which includes recommendations of the 5G Toolbox. The article carries out an analysis to answer the question of whether the provisions of the Bill regarding proceedings in the case of the so-called high-risk suppliers are consistent with the Constitution and basic procedural principles, and in particular whether legal guarantees have been provided for participants in the proceedings regarding high-risk suppliers. The research hypothesis is that not all proposed regulations in this area meet the previously indicated requirements. The analysis takes into account the proposed regulations regarding: proceedings concerning recognition of a supplier as a high-risk supplier; application of the provisions of the Code of Administrative Procedure in these proceedings and the content of issued decisions and remedies. Mainly the dogmatic-legal method, as well as the theoretical-legal method, is used.
Freedom of Expression and Hate Speech Regarding the Activities of Public Officials in Political Debate
Authors: Stępień-Załucka Beata
Published: August 2024

Freedom of expression has accompanied humanity for centuries. As societies have developed over the decades, it has evolved and changed. In parallel, the brutalisation of language has also progressed, leading to the emergence of hate speech. Today, hate speech is a global phenomenon, significantly impacting the speech of public figures. This is due to the fact that such statements reach a wide audience, which includes both supporters and opponents of such a person. Consequently, this leads to a wide-ranging debate where individual arguments lose relevance, overshadowed by the repetition of negative slogans and comments with hateful overtones. This article aims to delineate the boundary between freedom of expression and hate speech, highlighting the consequences associated with the use of hate speech by public figures. It seeks to prove the main thesis that hate speech in the activity of public figures is an unquestionably negative phenomenon and thus cannot benefit from the protection guaranteed under freedom of speech. Additionally, it posits that hate speech undermines the dignity of individuals and society, leads to a decline in the culture of speech, and diminishes both political and social culture. Consequently, it erodes the authority of public figures and harms the offices they hold by undermining trust in them.

Authors: Goswami Om Prakash , Shukla Aasheesh , Kumar Manish , Bhargava Anuja
Published: August 2024

The designs of first- and second-order digital low-pass filters with infinite impulse response (IIR) are presented in this letter, utilizing a meta-heuristic optimization technique. Firstly, the analog transfer functions of the first and second- order filters are considered, followed by the application of an L1-norm-based multi-verse optimization algorithm to directly emulate their magnitude-frequency response in the digital domain. The obtained magnitude-frequency response shows superior matching with the analog counterpart for different cut-off frequencies of the first- and second-order filters, as well as varying quality factors for the second-order filter. In comparison to the filter’s magnitude-frequency response obtained through traditional bilinear transform and advanced operators, the proposed technique accurately manifests the analog magnitude-frequency response in the digital domain.

Authors: Rahim Eman Abdel , Essai Mohamed Hassan , Hamad Ehab K. I.
Published: August 2024

Artificial neural networks (ANNs) have gained a lot of attention from researchers in the past few years and have been employed on a large scale. They have also been gaining momentum in wireless communication systems. For efficient vehicle-to-vehicle (V2V) channel communication, a sparse multipath channel issue must be studied. To minimize the multipath effect, a time reversal (TR) operation and time division synchronization orthogonal frequency division multiplexing (TDS-OFDM) have been appealing because of their fast synchronization and active spectral efficiency. To improve the transceiver's execution in a frequency-selective fading channel environment, an OFDM system is used to reduce inter- symbol interference (ISI). Simultaneous Orthogonal Matching Pursuit (SOMP) channel state estimator algorithm suffer from high computational cost and high computational complexity. The ANN algorithm has better performance than SOMP algorithm. The proposed neural network technologies have lower complexity than the SOMP algorithm. The application of ANN is capable of solving complex problems, such as those encountered in image, signal processing and have been implemented for channel estimation in OFDM. The proposed ANN outperformed the SOMP algorithm with regard to signal compensation. Overall, the ANN algorithm achieved the best performance. This study proposes an ANN-based sparse channel state estimator. Regarding the bit error rate (BER) metric, the proposed estimator outperforms the channel estimation approach based on the SOMP. The simulation results confirm the efficacy of the proposed approach.
Integrating GPS and WiFi signal strength analysis for enhanced building entrance localization using fuzzy logic
Authors: Abadleh Ahmad
Published: August 2024

This paper presents a method for improving the accuracy of determining a person's proximity to a building entrance in urban and indoor settings, where the Global Positioning System (GPS) and Wireless Fidelity (WiFi) signals are often interfered with. Fuzzy logic can be applied to variations in signal strengths in order to interpret the inverse relationship between GPS signals weakening and WiFi signals strengthening as a person approaches or enters a building. As a result, a fuzzy set for GPS signal strengths between 14 and 33 dBm and WiFi signal strengths between –68 and –31 dBm is created, separating them into weak, medium, and strong signals. By using fuzzy rules, the system can accurately determine if a user is 'far,' 'near,' or 'at' an entrance, mimicking real-life transitions from outdoor to indoor environments. The accuracy of this approach exceeded 90% based on real-world data, and it significantly improved user experience in navigation applications, particularly in cases where GPS does not work well.
The Use of Multimodal Service Level and Artificial Neural Networks for the Improvement of Public Transport
Authors: Maleanu Mihai , Ungureanu Valentin-Vasile
Published: August 2024

Most of the major modern cities of the world face problems due to traffic conditions. However, in the last decade the degree of motorization combined with increased urbanization and population density causes excess traffic capacity during peak hours on the main streets of already congested cities. In these circumstances, public transport should provide a reliable and alternative choice for daily travel. The article is focused on the development of models to quantify the environment in which public transport operates and the quality of services. Also, the use of artificial neural network as a tool for assisted analysis of all traffic components can help local authorities to improve the performance of public transport service. In addition, improvements in the reliability of public transport service can reduce travel costs and change the modal split.

Published: August 2024

The Paper presents the results, interpretation and intervention measures obtained from inclinometer monitoring performed for a retaining structure built for the accomplishment of a hydrotechnical structure on Jiu River. The accomplishment of the hydrotechnical structure on Jiu River required a retaining structure of approximately 100m length adjacent to the slope which is crossed by the railway line Tg. Jiu - Simeria. The retaining structure made of 1500mm piles also keeps in safe condition the adjacent E79 Road section.

Monitoring the behavior of the support structure and of the slope, the layout and the depth of the monitoring equipments, is the result of a complex analysis of the site, of the neighborhoods and the risks to be monitored and managed. This paper presents the “peak of the iceberg” related to site monitoring, being the result of several steps necessary to be performed in order to accomplish the monitoring program: establishing geotechnical or structural issues that require resolution / tracking, establishing the concept of monitoring systems and monitoring plan, establishment of: monitored points, equipment, frequency and type of data acquisition, processing methods, interpretation and issue resolutions for the data.

The results of the geotechnical monitoring and topographical survey compared with the design assumptions can lead to intervention measures to ensure and restore structural stability for the construction during execution stage or exploitation stage.

Published: August 2024

Road traffic safety is a series of methods and measures aimed to reducing the risk of injury for road users.

Road accidents are events that have an extremely strong socio-economic impact on society as a whole and directly on its members.

The road is a basic component of the road safety system and is represented by the road and the area adjacent to it, which influences the flow of road traffic. Basically, the driver “reads” the road and based on that information adopts the behaviour, mainly speed.

The road elements of the road and the homogeneity of these characteristics, visibility in curves, the layout of intersections, the uniformity and roughness of the road surface are only some of the essential elements of the traffic safety study at the design stage. But even on a very well-designed road, many accidents occur because of the other possible factors.

The road elements characteristic of roads are the totality of the road components in plan view, elevation and cross section.

In this case study, a section of road of technical class III was considered.

The design speed of the road section studied is 80 km/h and the lane width is 3.50 m, according to the technical standards in force.

The study was carried out for design speeds of 80 km/h and 60 km/h respectively, the height of the eyes will be considered as 1.00 m, 1.10 m, 1.20 m and 1.30 m, and for the height of the obstacle will have variable height, more precisely, for the speed of 80 km/h the heights will be 0.20 m, 0.40 m, 0.60 m, 0.80 m, 1.00 m, and for the speed of 60 km/h, they will be 0.00 m, 0.10 m, 0.20 m.

Authors: Singh Sanjay Kumar , Singh Vijay Lakshmi
Published: August 2024

Fatalities and injuries on account of road traffic crashes are a public health scourge of rising concern in the metropolitan cities of Uttar Pradesh (UP) in India. While in many Indian cities, including Delhi, the situation is generally improving, UP’s cities face a deteriorating situation. Currently, road traffic accidents on UP’s city roads claim 29% more lives, in comparison to the past decade. Hence, there is an urgent need to take cognizance of this increasingly alarming problem and take requisite measures to arrest this situation. Particular interventions like legislation enforcements for controlling vehicle speed, use of seatbelts, helmets, design of safer roads, construction of separate paths for two-wheelers and segregated green modes for bicycles and pedestrians, promotion of public transport, and setting up of emergency trauma care networks have immense potential to decrease the prevalence and impact of road traffic crashes in the metropolitan cities of UP.
Preferences of Immigrants on Immigration: Convergence or Persistence? Evidence from the European Social Survey
Authors: Galli Fausto , Russo Giuseppe
Published: August 2024

This article studies the immigrants’ attitude towards immigration with special emphasis on the transition from the first to the second and the 1.5 generations. We use European Social Survey (ESS) data for the 2002-2020 period, which include many questions that allowed us to estimate the preferences of immigrants on economic, social and cultural consequences of immigration. As general evidence, we find that immigrants of all the considered generations show more favor to immigration than natives. Besides, our results reveal that the gap with the natives shows a remarkable degree of persistence through generations for many of the indicators we analyzed. We also observe that the opinions of individuals who immigrated during childhood (generation 1.5) look not different from second-generation immigrants. For what concerns the main determinants of the support of immigrants for immigration, our results suggest that citizenship and age have a negative impact, whereas religiosity, education level and the feeling of being discriminated have a positive one. These results are generally consistent with the previous literature. Finally, ESS data allowed us to investigate an effect of intergenerational ongoing migration. We considered migrants born to fathers who were first generation migrants. These individuals are second generation in the origin country, and first generation in the destination country. Their favor for further inflows of migrants is still higher compared to the natives of destination countries, but lower compared to migrants of the same origin who were not born to immigrant fathers.

Business voluntary efforts to improve society and the environment are referred to as corporate social responsibility (CSR). As such, the idea of CSR is embodied in Nigerian enterprises continuous commitment to environmental improvement. Using ten Nigerian consumer goods manufacturers that are listed on the Nigerian Stock Exchange, this study looked at the relationship between CSR and long-term financial success over the course of ten years (2012-2021). The study used panel data and multiple linear regression with E-views software. Economic responsibility has a small and negative impact on ROA, whereas legal duty has a substantial and beneficial impact, per the study. ROA is positively and significantly impacted by ethical duty as well. The analysis also showed that while legal obligation has a negligible but modest impact and ethical responsibility has a slight but favorable impact on ROE, economic responsibility has a considerable and positive impact on ROE. Since there is a clear correlation between moral responsibility and business success, research on return on assets (ROA) suggests that it should be encouraged. Legal responsibility and the firm’s performance are positively correlated, albeit this relationship is not statistically significant. The ROA research indicates that since it greatly enhances business performance, economic responsibility ought to be encouraged. The organization needs to manage legal liabilities to get the intended results. There was positive association between business performance and ethical responsibility, even if it was not statistically significant.
Joshua, King David, and the Flying Nun: Doodles and Reader Annotations in Post-Holocaust Yiddish Primers for Children
Authors: Borden Miriam
Published: August 2024

Students in Yiddish supplementary schools used texts produced by educators steeped in a diaspora nationalist pedagogy that reflected the ideological coupling of Yiddish and Yiddishkeit: the Yiddish language informed one’s sense of Jewishness. By the 1960s, doodles students left in their schoolbooks challenged this coupling of language and identity. Though it is generally supposed that Yiddish primers ultimately tell us more about the aspirations of adults than they do about the experiences of children, reading these texts together reveals that children evolved their own relationship between Yiddish and Jewishness that was far more subtle than what they encountered in their textbooks. Postwar primers emphasize maintaining the Yiddish language on American soil, to the exclusion of the external culture; children’s doodles argue that more important than preserving the language was locating Yiddishkeit in the culture around them.
“Easier to Understand but More Difficult to Digest”: Student Experiences with Israeli Yom HaZikaron Cartoons
Authors: Reingold Matt
Published: August 2024

Yom HaZikaron, Israel’s Remembrance Day, has received considerable scholarly attention, with research published about how the country’s youth understand the day but there has been no comparable data from diaspora Jews. This article presents findings about how a cohort of Canadian Jewish teenagers participating in a gallery walk of Israeli political cartoons provided new ways of thinking about and relating to Yom HaZikaron. The data revealed that students care about Yom HaZikaron but struggle to form a connection to the day. Political cartoons that depicted personal loss led students to form new insights into the day and to new associations and connections with Israelis.
Evaluation of biomass yield and seed yield of vetch and oats variety mixtures
Authors: Yadeta Gemechis Lencho
Published: August 2024

A different species and varieties of forage vetch and oat were identified to successfully adapt and perform in the highlands of Bale. However, their oat-vetch mixture was not evaluated. The study was conducted to evaluate the effect of variety on biomass yield and seed yield of oats and vetch grown in pure stand and mixtures. This experiment was conducted at Sinana Agricultural Research Center, Bale zone, southern Ethiopia, during May 2023. A total of five treatments were developed for sole and mixed stands using two oat varieties and one vetch variety. A trial was arranged in RCBD with five replications. The recorded data are morphological parameters, biomass, tiller, side branch, seedling count and seed yield were calculated and subjected to analysis of variance (ANOVA) following the GLM procedures in SAS version 9.4. The highest dry matter yield (DMY) 18.6 t ha-1 was observed by the mixture of Gebisa variety + oat Bonsa variety. Among the mixture treatments, Gebisa variety + oat Bonsa variety had the highest seed yield (2.9 t ha-1) while the pure stand Bona-bas variety had the seed yield (1.28 t ha-1). The dry matter yield (DMY), of mixtures of Gebisa variety + oat Bonsa variety mixtures was better than pure stands. Based on the current result it is concluded that oat Bonsa variety + Gebisa variety mixtures had relatively higher yield biomass. Generally, in the present study on Oat-vetch mixture, there is higher yield biomass so, Animal performance must be tested.
Ammianus Marcellinus and Three-Dimensional Rainbows
Authors:   Independent researcher, Cambridge, MA, Rushkin Ilia
Published: August 2024

We examine Ammianus Marcellinus' scientific digression on the rainbow, where the rainbow colors are listed in an unusual order. We suggest an explanation for the order and conclude that, according to a scientific theory current at the time, the rainbow was viewed as a three-dimensional arrangement in the sky, with colored bands positioned at different distances from the observer. This perspective aligns with the rejection of the Aristotelean rainbow theory, which is an evolution of ideas observable in its intermediate stages in Seneca’s “Natural Questions” and in the commentary on Aristotle’s “Meteorology” written by Alexander of Aphrodisias.
The Human and the Divine in the First Stasimon of Sophocles’ Antigone
Authors:   IFILNOVA/NOVA University Lisbon, Lima Paulo Alexandre
Published: August 2024

The first stasimon of the Antigone has the second antistrophe as its key moment. If read in connection with the whole of the play, the second antistrophe points in advance to a conflict between two inadequate forms of relationship between the human and the divine as the reason for the catastrophe that befalls Thebes. It represents a microcosm of the whole play, which deals with a conflict between Antigone’s and Creon’s inadequate forms of relating to the divine. It does not refer to just one of the protagonists but to both simultaneously. By referring to what an adequate relationship between the human and the divine is and what it is not, it establishes a decisive criterion from which not only the play’s outcome but also the meaning of every human society can be assessed.
