We select and characterize a sample of massive (log(M
*/M
⊙) > 10.6) quiescent galaxies (QGs) at 3 < z < 5 in the latest Cosmological Evolution Survey catalog (COSMOS2020). QGs are selected using a new rest-frame color-selection method, based on their probability of belonging to the quiescent group defined by a Gaussian mixture model (GMM) trained on rest-frame colors (NUV − U, U − V, V − J) of similarly massive galaxies at 2 < z < 3. We calculate the quiescent probability threshold above which a galaxy is classified as quiescent using simulated galaxies from the shark semi-analytical model. We find that, at z ≥ 3 in shark, the GMM/NUVU − VJ method outperforms classical rest-frame UVJ selection and is a viable alternative. We select galaxies as quiescent based on their probability in COSMOS2020 at 3 < z < 5, and compare the selected sample to both UVJ- and NUVrJ-selected samples. We find that, although the new selection matches UVJ and NUVrJ in number, the overlap between color selections is only ∼50%–80%, implying that rest-frame color commonly used at lower-redshift selections cannot be equivalently used at z > 3. We compute median rest-frame spectral energy distributions for our sample and find the median QG at 3 < z < 5 has a strong Balmer/4000 Å break, and residual NUV flux indicating recent quenching. We find the number densities of the entire quiescent population (including post-starbursts) more than doubles from 3.5 ± 2.2 × 10−6 Mpc−3 at 4 < z < 5 to 1.4 ± 0.4 × 10−5 Mpc−3 at 3 < z < 4, confirming that the onset of massive galaxy quenching occurs as early as 3 < z < 5.
KIC 7284688: A Solar-type Eclipsing Binary with Rapidly Varying O’Connell Effect
Authors: Pan Yang , Zhang Xiaobin
Published: May 2023

We present comprehensive photometric and spectroscopic study of the short-period eclipsing binary KIC 7284688 based on the Kepler, TESS, and LAMOST data. The radial-velocity analysis indicates that it is a triple-lined system composed of a nearly equal-mass binary plus a line-of-sight star. The masses and radii of the components in the binary are measured to be M
1 = 1.142 ± 0.020M
⊙, R
1 = 1.204 ± 0.051R
⊙, and M
2 = 1.119 ± 0.019M
⊙, R
2 = 1.149 ± 0.052R
⊙. In addition to the eclipses, the light curves of the binary exhibit exhibit rapidly changing O’Connell effect, namely the inequality in light maxima, which could be attributed to the asynchronous rotation of the starspots. We analyzed the variability in the data of light residuals, the difference between light maxima (Max.I−Max.II) as well as the epochs of light minima and determined a rotation period of 0.644 days. Moreover, we detected a quasiperiod with ∼213 days from both the data of (Max.I−Max.II) and light times of minima, which is almost identical to the beat between the rotation period (∼0.644 days) and the orbital period (∼0.646 days). We conclude that the quasiperiodic variations of the O’Connell on the system are probably related to the starspot migration and this is a very rapid variation compared to the magnetic cycles with timescales ranging from years to decades.

When discovered, SN 2017egm was the closest (redshift z = 0.03) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy. Thus, it has since been extensively observed and studied. We report spectroscopic data showing strong emission at around He i
λ10830 and four He i absorption lines in the optical. Consequently, we classify SN 2017egm as a member of an emerging population of helium-rich SLSNe-I (i.e., SLSNe-Ib). We also present our late-time photometric observations. By combining them with archival data, we analyze high-cadence ultraviolet, optical, and near-infrared light curves spanning from early pre-peak (∼−20 days) to late phases (∼+300 days). We obtain its most complete bolometric light curve, in which multiple bumps are identified. None of the previously proposed models can satisfactorily explain all main light-curve features, while multiple interactions between the ejecta and circumstellar material (CSM) may explain the undulating features. The prominent infrared excess with a blackbody luminosity of 107–108
L
⊙ detected in SN 2017egm could originate from the emission of either an echo of a pre-existing dust shell or newly formed dust, offering an additional piece of evidence supporting the ejecta–CSM interaction model. Moreover, our analysis of deep Chandra observations yields the tightest-ever constraint on the X-ray emission of an SLSN-I, amounting to an X-ray-to-optical luminosity ratio ≲10−3 at late phases (∼100–200 days), which could help explore its close environment and central engine.
The Hα Broadband Photometric Reverberation Mapping of Four Seyfert 1 Galaxies

Published: May 2023

Broadband photometric reverberation mapping (PRM) has been investigated for active galactic nuclei (AGNs) in recent years, but mostly on accretion disk continuum RM. Due to the small fraction of broad emission lines in the broad band, PRM for emission lines is very challenging. Here, we present an ICCF-Cut method for broadband PRM to obtain the Hα broad-line lag and apply it to four Seyfert 1 galaxies: MCG+08-11-011, NGC 2617, 3C 120, and NGC 5548. All of them have high-quality broadband lightcurves with daily/subdaily cadences, which enable us to extract Hα lightcurves from the line band by subtracting the contributions from the continuum and host galaxy. Their extracted Hα lightcurves are compared with the lagged continuum-band lightcurves, as well as the lagged Hβ lightcurves obtained by spectroscopic RM (SRM) at the same epochs. The consistency of these lightcurves and the comparison with the SRM Hβ lags provide support for the Hα lags of these AGNs, in a range from 9 to 19 days, obtained by the ICCF-Cut, JAVELIN, and χ
2 methods. The simulations for evaluating the reliability of the Hα lags and the comparisons between the SRM Hβ and PRM Hα lags indicate that the consistency of the ICCF-Cut, JAVELIN, and χ
2 results can ensure the reliability of the derived Hα lags. These methods may be used to estimate the broad-line region sizes and black hole masses of a large sample of AGNs in large multi-epoch, high-cadence photometric surveys such as LSST in the future.

Published: May 2023

We collected the archival data of blazar OJ 287 from heterogeneous very long baseline interferometry monitoring programs at 2.3, 8.6, 15, and 43 GHz. The data reduction and observable extraction of those multiband, multiepoch observations are batch-processed consistently with our automated pipeline. We present the multivariate correlation analysis on the observables at each band. We employ the cross-correlation function to search the correlations and the Monte Carlo technique to verify the certainty of correlations. Several correlations are found. The foremost findings are the correlations between the core flux density and the jet position angles on different scales, which validated the plausible predictions of the jet with precession characteristics. Meanwhile, there is a variation in the offset between the core electric vector position angle and the inner-jet position angle over time at 15 and 43 GHz.

Published: May 2023

We present a seven-band (g, r, i, z, y, NB816, NB921) catalog derived from a Subaru Hyper Suprime-Cam (HSC) imaging survey of the North Ecliptic Pole (NEP). The survey, known as HEROES, consists of 44 deg2 of contiguous imaging reaching median 5σ depths of g: 26.5, r: 26.2, i: 25.7, z: 25.1, y: 23.9, NB816: 24.4, and NB921: 24.4 mag. We reduced these data with the HSC pipeline software hscPipe, and produced a resulting multiband catalog containing over 25 million objects. We provide the catalog in three formats: (1) a collection of hscPipe format forced photometry catalogs, (2) a single combined catalog containing every object in that data set with selected useful columns, and (3) a smaller variation of the combined catalog with only essential columns for basic analysis or low-memory machines. The catalog uses all the available HSC data on the NEP and may serve as the primary optical catalog for current and future NEP deep fields from instruments and observatories such as SCUBA-2, eROSITA, Spitzer, Euclid, and JWST.
The Increasingly Strange Polarimetric Behavior of the Barbarian Asteroids

Published: May 2023

Polarization phase-curve measurements provide a unique constraint on the surface properties of asteroids that are complementary to those from photometry and spectroscopy and have led to the identification of the “Barbarian” asteroids as a class of objects with highly unusual surfaces. We present new near-infrared polarimetric observations of six Barbarian asteroids obtained with the WIRC+Pol instrument on the Palomar Hale telescope. We find a dramatic change in polarimetric behavior from visible to near-infrared for these objects, including a change in the polarimetric inversion angle that is tied to the index of refraction of the surface material. Our observations support a two-phase surface composition consisting of high albedo and high index of refraction inclusions with a small optical size scale embedded in a dark matrix material more closely related to C-complex asteroids. These results are consistent with the interpretation that the Barbarians are remnants of a population of primitive bodies that formed shortly after calcium-aluminum-rich inclusion (CAIs). Near-infrared polarimetry provides a direct test of the constituent grains of asteroid surfaces.

AIM: This study aimed to study the probiotic lactic acid bacteria obtained from fermented Etawa goat’s milk (Yogurt) from Kopelma Village, Darussalam District, Banda Aceh City, Aceh Province, Indonesia.

METHODS: This research was conducted in vitro on the growth of Streptococcus pyogenes bacteria on Yogurt using the biomass index test procedure, Ph change, and anti-adhesion test. Data obtained statistically in the form of graphs between S. pyogenes on variations in yogurt concentration and incubation time.

RESULTS: At concentrations of 25%, 50%, and 100% indicated that Yogurt had good inhibition for the growth of S. pyogenes bacterial colonies <300 CFU (0.5 McFarland). The effect of incubation time determines the number of colonies, at incubation time of 24 h, 48 h, and 72 h. Yogurt can give a good response to S. pyogenes, as indicated by the increase in the Yogurt biomass index at a concentration of 100% with an incubation time of 48 h and 72 h. The best biomass index at incubation time of 24 h is at a concentration of 50%.

CONCLUSION: Yogurt pH did not change significantly, both based on incubation time and concentration. Anti-adhesion activity increased according to the incubation time. While the Yogurt concentration did not show a significant difference.

Published: May 2023

Dasyophthalma includes five species of medium-sized butterflies, all endemic from the Atlantic Forest of Brazil. All known species are univoltine and are dayflying, differently from other Brassolini that are mostly crepuscular. In despite of recent advances little is known about their natural history. Three out of the five species are included in the Brazilian Red List of threatened fauna and are of conservation concern. The present study provides for the first time a phylogenetic assessment of all Dasyophthalma species based on a molecular approach based on three loci. Also, the taxonomic status of D. rusina delanira was revised based on molecular data. In addition, up-to-date distributional data and conservation aspects of the threatened species from the genus are presented and discussed. The molecular phylogenetic analysis supports the monophyly of Dasyophthalma, with Dynastor darius as its sister-group, and, combined with a genetic divergence analysis, supported Dasyophthalma delanirastat. rest. as a valid name to species-level, sister-group to D. geraensis (and not a subspecies of D. rusina). The geographical range (extent of occurrence and area of occupancy) for all five species are presented, showing that these are very restricted for D. delanirastat. rest. and D. geraensis, following the distributions of the high-altitude forests. As much biological information about the genus is lacking, the present study can serve as a starting point for future studies on Dasyophthalma, adding information that can be crucial for future conservation actions and essential to assure the future of the threatened species in this genus.

Published: May 2023

Woody oil plants are important economic trees which are widely cultivated and distributed throughout China. Surveys conducted during 2020 and 2021 on several woody oil plantations from five regions of Sichuan Province, China, revealed a high diversity of Botryosphaerialean fungi. The identification of 50 botryosphaeriaceous isolates was carried out based on both morphology and multi-gene phylogenetic analysis of internal transcribed spacer region (ITS), translation elongation factor 1-alpha gene (tef1) and β-tubulin gene (tub2). This allowed the identification of twelve previously known Botryosphaeriales species: Aplosporella prunicola, A. ginkgonis, Barriopsis tectonae, Botryosphaeria dothidea, Bo. fabicerciana, Diplodia mutila, Di. seriata, Dothiorella sarmentorum, Neofusicoccum parvum, Sardiniella guizhouensis, Sphaeropsis citrigena, and Sp. guizhouensis, and four novel species belonging to the genera Diplodia and Dothiorella, viz. Di. acerigena, Di. pistaciicola, Do. camelliae and Do. zanthoxyli. The dominant species isolated across the surveyed regions were Botryosphaeria dothidea, Sardiniella guizhouensis and Diplodia mutila, representing 20%, 14% and 12% of the total isolates, respectively. In addition, most isolates were obtained from Pistacia chinensis (14 isolates), followed by Camellia oleifera (10 isolates). The present study enhances the understanding of Botryosphaeriales species diversity on woody oil plants in Sichuan Province, China.

Integrated analyses using maximum likelihood (ML), Bayesian inference (BI), principal component analysis (PCA), discriminate analysis of principal components (DAPC), multiple factor analysis (MFA), and analysis of variance (ANOVA) recovered two new diagnosable species of gekkonid lizards in the genus Dixonius, one from the Central Highlands, Gia Lai Province, Vietnam and another from the Vientiane Province, Laos. Phylogenetic analyses based on the mitochondrial NADH dehydrogenase subunit 2 gene (ND2) and adjacent tRNAs showed that Dixonius gialaiensissp. nov. is the sister species of D. minhlei from Dong Nai Province, Vietnam and is nested within a clade that also includes the sister species D. siamensis and D. somchanhae. Dixonius muangfuangensissp. nov. is the sister species to D. lao from Khammouane Province, Laos and is embedded in a clade with D. vietnamensis, D. taoi, and undescribed species from Thailand. Multivariate (PCA, DAPC, and MFA) and univariate (ANOVA) analyses using combinations of 15 meristic (scale counts), six morphometric (measurements), and five categorical (color pattern and morphology) characters from 44 specimens encompassing all eight species of Dixonius from Vietnam and Laos clearly illustrate Dixonius gialaiensissp. nov. and Dixonius muangfuangensissp. nov. are statistically different and discretely diagnosable from all closely related species of Dixonius. These integrative analyses also highlight additional taxonomic issues that remain unresolved within Dixonius and the need for additional studies. The discovery of these new species further emphasizes the underappreciated herpetological diversity of the genus Dixonius and illustrates the continued need for field work in these regions.
La transformation du rôle des managers par les plateformes numériques de bien-être au travail dans un contexte de télétravail.
Authors: Le Vaillant Nikolaz , Dumas Marc
Published: May 2023

Cette étude exploratoire cherche à analyser les transformations du rôle des managers que le recours aux plateformes numériques de bien-être au travail a pu amener dans un contexte de télétravail. Les principaux risques liés au télétravail décrits dans la littérature sont la perte de lien, la difficulté à collaborer, l’isolement, le travail sans fin et le brouillage des frontières entre vie professionnelle et vie privée. Notre objectif est d’étudier comment ces plateformes peuvent affecter le contrôle et l’accompagnement des équipes à distance et quelles sont les réponses managériales apportées à ces nouvelles problématiques. Pour cela, nous avons interrogé au moyen de 60 entretiens semi-directifs un réseau d’acteurs de la santé au travail, y compris les prestataires des plateformes, et avons récolté les retours d’expériences et leur usage en contexte de télétravail. Les résultats éclairent comment le contrôle peut évoluer et se traduire par un effacement du manager au profit de l’autocontrôle, voire de l’auto-management des salariés, tout en plaçant la gestion émotionnelle et la prévention des risques psychosociaux au cœur de leur rôle émergent.

Published: May 2023

As a new learning model that breaks the barriers of time and space, virtual simulation covers a variety of learning behaviors. To evaluate the effect of virtual simulation teaching on college students’ learning behavior, with the help of a course integration model which reduces the omissions in the process of data collection, the data collection process of college students on the online platform was constructed. The collected data before storage were preprocessed which reduces the repetition rate of the original data of learning behavior, and the correlation between the collected data and the actual learning behavior was analyzed. Results show that learners’ specific process of online learning can be summarized into four stages: login trajectory, core learning, social interaction, and learning evaluation. Then, the actual final examination scores of the college students who participated in the test are all above 90 points, and their academic achievements are significantly improved. The use of the virtual simulation teaching method also enhances the overall satisfaction of college students with experimental courses, and the accuracy of the analysis results of course results is 99%, with better results. Conclusions are helpful to build college students' active learning consciousness of virtual simulation teaching courses.

Published: May 2023

With the continuous application of intelligent technology, Virtual Reality (VR) technology has become a hot topic of development. VR has unique advantages in the field of the teaching due to its characteristics of immersion, interaction and sociality. Therefore, it is necessary to pay attention to the influencing factors of VR teaching on learning effect, to improve the quality of courses through improvement of relevant influencing factors and to help to reverse further development of VR technology. A questionnaire survey on influencing factors of teaching application of VR technology on the learning effect of college students was conducted. Through data collection of students of various majors and grades in multiple comprehensive universities, statistical analysis and regression empirical analysis were carried out. Results show that different majors, grades, and students’ autonomous learning ability have different influences on the teaching application of VR technology. In addition, there are many influencing factors such as network fluency, situational sense of interaction, teachers’ teaching ability and the difficulty of course design, etc. According to the conclusions, some suggestions on improving VR teaching and learning effect are put forward. It is expected to improve the learning effect and efficiency of college students under the application of VR teaching, and promote the further development of VR teaching.
Digital Management of Teaching Cases in Colleges and Universities Based on Cluster Analysis
Authors: Wu Run , Wang Jinping
Published: May 2023

The necessity of digital management of teaching cases is mainly reflected in the aspects of improving teaching quality, facilitating retrieval and storage, achieving cross-platform sharing, conducting real-time updating, saving resources, and carrying out data analysis and evaluation. However, there are still some defects in the existing management models or methods, which lead to difficulties in data storage and retrieval, and affect the utilization efficiency of teaching resources. To this end, this article takes the Chinese language and literature major as an example, and studies the digital management of teaching cases in colleges and universities based on cluster analysis. First of all, it quantifies the quality of digital management of teaching cases, enables resource demanders to accurately select digital resources of teaching cases that meet their teaching or learning needs through the evaluation index of service quality when faced with diversified digital resources of teaching cases in colleges and universities. The clustering algorithm is used to mine potential topics and patterns in teaching cases, which improves the classification efficiency of teaching cases and enables educators to have a deeper understanding of teaching content and educational needs. It uses "absolute index", "incremental index" and "fluctuation index" to construct the similarity measurement distance function of the basic attributes of teaching cases in colleges and universities and uses the Ward method based on variance analysis to classify the characteristics of teaching cases in colleges and universities. Experimental results verify the effectiveness of the proposed method.

Published: May 2023

This final chapter is a critique, where each chapter is considered a case. Data were extrapolated by content analysis to situate this discussion about Black students within the context of the well-being in schools. The emergent themes from the intersecting realities of each case were also framed around the following question: What are the experiences that influence their well-being in environments often characterized by marginalization? Findings lead to a discussion about who is responsible for Black student well-being. Finally, concluding thoughts bring about possibilities for successful pathways for the well-being of Black students from African perspectives.
Rehabilitation Through the Arts

Published: May 2023

Prison rehabilitation and its impact on different populations, such as women, is not a new concept. Yet, efforts to create healing and non-judgment spaces are continuing to grow and undergoing evaluation. One of these alternative treatments is art therapy. The present review makes use of literature to explore the connection and effective between art therapy, prison rehabilitation, and women. Using the example of how the results of art therapy in treatment spaces can differentiate according to gender, this research shows that mental health among women is more prominent in comparison to men. The results revealed that woman -in general- through different approaches, had effective results emerging from art therapy in prison rehabilitation. In addition, it in most cases, the literature revealed that during prison rehabilitation, women react better to art therapy than men. This chapter argues that the implementation of art therapy as a form of treatment during prison rehabilitation is an effective method for incarcerated women.

The lasting positive impact of Art Therapy on clients is expansive and widely understood, however there has been little research done to quantify this data. The research found that the data that is available shows a significant, positive impact on clients who attend art therapy as a means of treatment for personality, mood, and psychotic disorders as well as those with disorders characterized by varying levels of cognitive deficit. This review analyzes the effects of taking part in an art therapy program on the aforementioned groups and addresses the issue of accessibility to care, weighing the ethics of experiential, self-directed art therapy.

Applications of the Internet of Things and Machine Learning Using Python in Digital Marketing
Authors: Singh Arun Kumar
Published: May 2023

The internet of things (IoT) is a network of physical objects or “things” embedded with electronics, software, sensors, and network connectivity, which enables them to collect and exchange data. These objects can include everyday devices such as smart thermostats, home security systems, wearable fitness trackers, and even vehicles. However, IoT also raises concerns about privacy, security, and reliability, as the increasing number of connected devices creates new opportunities for cyber attacks and data breaches. As such, the development and deployment of IoT technology must be done in a responsible and secure manner. Through the use of sensors, it is now possible to collect, transmit, and transform data into knowledge. The marketing and sales sectors are capable of using data gathered through IoT to interact with customers on an individual basis. Python is an object oriented, scripted and interpreted language for both learning and real-world programming. Work in this chapter first introduces Python as a language, and gives summary about data science, machine learning, and IOT.

Authors: Lukyanchuk Olexander , Turcheniuk Vasyl , Koptyuk Roman
Published: May 2023

This section analyses the technologies and means of traditional deep loosening as an agro-ameliorative measure, and their inconsistency with the requirements for improving the technology of water regulation of ameliorated lands in changing climatic conditions is determined. Therefore, it is advisable to switch from the traditional and most widespread technologies of slot and strip loosening to continuous loosening in profile and area, as well as differentiated loosening of deep soil horizons. It is proved that improved deep loosening can be the most effective means of ensuring the necessary filtration and simultaneous accumulation of excess soil moisture to ensure maximum productivity of ameliorated land throughout the entire growing season. Its implementation in the conditions of Polesie of Ukraine contributed to the improvement of water-physical properties, water permeability, and accumulating ability of the most common drained sod-podzolic soil, which provided an increase in the yield of cultivated crops by 20 ... 40%
Peculiarities of Environmental Risk Management in Nature Management Projects
Authors: Frolenkova Nadiia , Prykhodko Natalіia
Published: May 2023

The selection and justification of the feasibility of any environmental project, including water projects, are always associated with the analysis of future events and uncertainty of the outcome of the project. Therefore, one of the most important tools of project management is a risk management framework. Risks usually arise from the uncertainty and variability of the economic, environmental, political, social environment, as well as the different operation conditions of a particular object. Weather and climate risk, as a subtype of general environmental risk, reflects the degree of loss of potential yields, and consequently the amount of income, as a result of uncontrolled meteorological factors. Reducing such risk provides a decrease in the impact of adverse natural factors on the efficiency of economic activity, and hence on the degree of technological excellence and environmental reliability of the selected alternative design solutions.

Authors: Yao Zhao , Hu Yong , Peng Xingzhi , He Jiapan , Cheng Xuming
Published: May 2023

Due to the gradual increase in daily power consumption by businesses and individuals, the power industry has seen an increased need to deploy more power equipment. This has led to a significant rise in the data generated by electrical equipment, a trend noted by the International Journal of Emerging Electrical Power Systems. In order to process, analyze, and manage such large amounts of data, it is necessary to introduce knowledge mapping technology into the power field. This technology allows the power data operation monitoring platform to obtain useful data from a large amount of information. In light of this phenomenon, based on an analysis of the requirements for platform construction and design principles, combined with the knowledge map reasoning method, this paper has effectively studied the construction of the power data operation monitoring platform and tested the performance of the experimental platform by assessing the response time of each functional module, data correctness verification, and data standard management.
Impacts of Directionality on Disfluency of English-Chinese Two-Way Sight Translation
Authors: Yang Fan , Gao Fen , Zhang Kexin
Published: May 2023

This study explores the impacts of directionality on disfluency of sight translation (ST) between English and Chinese. The author adopts four disfluency indicators, namely silent pause (SP), filled pause (FP), repetition (Rt), and repair (Rr) to answer: (1) What are the features of disfluency in ST in two directions? (2) What is the correlation between directionality and disfluency in ST? The results show: (1) The incidence of SP is the highest in both E-C and C-E ST, followed by FP, then Rr, and finally Rt; many student interpreters do the most basic pre-task preparation poorly, leading to a large number of SPs; many SPs coincide with respiration and those over 10 seconds occur only in E-C ST; (2) There are no statistically significant differences between E-C and C-E ST in terms of the four disfluency indicators. In other words, directionality exerts no significant effect on disfluency of student interpreters' ST.

Published: May 2023

La violenza o aggressione verso gli infermieri sul luogo di lavoro è un evento estremamente comune, soprattutto nelle aree critiche ed emergenziali ospedaliere. Negli ultimi anni il problema sembra essersi palesato anche in altre realtà, intra- ed extra-ospedaliere, rendendo il fenomeno sempre più all'ordine del giorno. Molti sono gli studi che identificano le importanti conseguenze fisiche, psico-sociali ed economiche per i soggetti e le istituzioni che subiscono questo fenomeno, ma lo studio e la prevenzione della violenza si colloca ai primi posti delle agende delle organizzazioni e agenzie per la sicurezza dei lavoratori e delle associazioni internazionali dei professionisti della salute.

Published: May 2023

In this article, a systematic review is carried out to identify random and systematic errors in studies on computer programming in pairs in higher education students. Methodologically, we applied the fundamentals of the PRISMA statement. One thousand one hundred eighty articles were selected from the Scopus, Web of Science, and IEEE Xplore databases. After a filtering process, the final sample was 23 23 articles. The results showed that couple programming has positive effects. The existence of both random and systematic errors was observed, which questions the internal and external validity. Further research is needed to establish the benefits of couple programming more precisely.

Residual Stress Measurement and Classification, Metallic Structural Alloy Products and Finished Parts
Authors:   AMS B Finishes Processes and Fluids Committee
Published: May 2023

The purpose of this standard is to provide uniform methods for defining, quantifying, and classifying the residual stress in metallic structural alloy products and finished parts. These stresses may exist within a single element, or they may be the result of a joining process. Such quantification and classification may be required when residual stresses within mill stock or preforms can impact further in-process distortion during machining or other processes, and when residual stresses within finished components can impact final mechanical properties and performance (especially strength, durability, and fracture performance).
The Unstable Text of Pan Tadeusz
Authors: Prussak Maria
Published: May 2023

The article discusses the changes introduced by the successive editors of Adam Mickiewicz’s narrative poem to the text version published by the poet himself. The most important one is undoubtedly the addition of the poem considered the “epilogue” to Pan Tadeusz, allegedly lost by Mickiewicz. No less radical are the interventions consisting in supplementing the text with fragments from the autograph or with the poet’s later additions made to the already printed text, as well as in corrective conjectures in instances regarded by the publisher as slips of the pen. The article compares the surviving authorial versions of the text, demonstrating that Mickiewicz himself treated his work as a continual process and tested new solutions on various occasions however, there is no evidence that he intended to introduce them into the printed text.
On the Road to A Fare-Free Public Transport Policy: A Case Study of The Wroclaw Anarchist Federation
Authors: Štraub Daniel
Published: May 2023

“Climate Alarm”, a position of Wroclaw public authorities, is an official recognition of issues linked to global climate changes highlighting the position of urban transport development on the sustainable development agenda. Wroclaw Anarchists Federation (WAF) has entered the debate over the further trajectory of the city by proposing the fare-free public transport policy (FFPT) as an instrument supporting the new path presented with the “Climate Alarm.” As the FFPT is being implemented for various reasons, this study uses the content and discourse analyses to explore not only the framing of the FFPT campaign but also how the call for FFPT adoption is set in motion. The WAF sees the FFPT as sustainable transport innovation, and their campaign is suitable for explaining the ecological and social rationale of the FFPT. However, it is not enough to shift the public discourse and mobilize public authorities to consider the FFPT as an option.
