Authors: Nadira Audria Izza , Ismanto Aris , Hakim Aradea R. , Ramdhani Andri
Published: March 2024

Selat Sunda merupakan perairan yang menghubungkan Laut Jawa dan Samudra Hindia, yang memisahkan Pulau Sumatra dan Pulau Jawa. Arus di perairan Selat Sunda bergerak sepanjang tahun dari Laut Jawa ke Selat Sunda. Pergerakan massa air dari Laut Jawa ke Samudra Hindia yang melewati Selat Sunda terjadi secara kontinu sepanjang tahun dengan kuantitas yang kecil dan sangat erat hubungannya dengan gradien permukaan laut (sea level). Penelitian ini bertujuan untuk mengidentifikasi pengaruh pasang surut terhadap pola arus permukaan perairan Selat Sunda yang memiliki beberapa faktor pembangkit arus seperti angin dan pasang surut. Penelitian ini menggunakan data yang berasal dari High Frequency Radar, yang merupakan teknologi yang digunakan untuk mengukur distribusi tenaga gelombang di laut terbuka dari jarak jauh secara real time dan bersifat kontinu dengan resolusi spasial dan temporal. Data jumlah pengukuran arus dari HF Coastal Ocean Dynamics Application Radar (CODAR) serta data tinggi muka air laut diperoleh dari situs Sea Level Monitoring iPASOET oleh Badan Informasi Geospasial periode bulan Mei – Juli 2019. Data arus permukaan laut dianalissis harmonik untuk memisahkan arus harmonik (pasut) dan arus non harmonik (residu) pada kedua titik penelitian. Berdasarkan pengolahan data, didapatkan persentase arus harmonik yang lebih besar dibandingkan dengan arus residu pada kedua komponen (zonal dan meridional) di kedua titik penelitian. Sehingga, arus permukaan di perairan Selat Sunda pada kedua titik penelitian teridentifikasi memiliki pengaruh pasang surut yang tinggi.

Intrusi air laut sering menjadi permasalahan daerah pesisir. Salah satu daerah pesisir yang mengalami kondisi intrusi adalah Kota Tegal. Keberadaan muara Sungai Ketiwon yang berada di Kota Tegal ini mengakibatkan intrusi yang semakin parah di wilayah ini. Penelitian ini bertujuan untuk mengetahui hubungan ketinggian air laut dan salinitas pada aliran Sungai Ketiwon melalui daya hantar listriknya. Penelitian ini dilakukan tanggal 13-16 Juni 2022. Metode yang digunakan dalam melakukan analisis data adalah menggunakan regresi linier. Variabel yang diukur meliputi ketinggian air laut dan daya hantar listrik. Distribusi daya hantar listrik secara vertikal digambarkan menggunakan software Ocean Data View (ODV) 4.0. Berdasarkan pengukuran di lapangan didapatkan nilai daya hantar listrik di sepanjang daerah penelitian berkisar antara 516 µs/cm hingga 1999 µs/cm. Sedangkan besarnya daya hantar listrik yang dihitung berdasarkan persamaan regresi, ketinggian air laut dan salinitas adalah 2494,33 µs/cm - 3631,176 µs/cm pada saat kondisi pasang dan 1428,332 µs/cm - 1672,517 µs/cm saat kondisi menuju surut. Hasil olahan menggunakan korelasi regresi linier didapatkan nilai R sebesar sebear 0,7 – 0,9. Angka tersebut mempunyai arti bahwa terdapat korelasi yang positif dan cukup kuat antara ketinggian air laut terhadap daya hantar listrinya.
Obrození tanga: nostalgie, naslouchání, experiment
Authors: Gotlib Matvei
Published: March 2024

This article examines the history and culture of Argentinian tango as a translocal social dance and emphasizes its revivalist component along with other characteristic features: nostalgia, listening, and experimentation. It represents the partial and the preliminary result of the author’s anthropological research that they are currently conducting as part of the doctoral programme at the Faculty of Humanities of Charles University in Prague. The author concludes that both nostalgic beliefs and the desire to create something new contribute to the process of tango revival.

The life of children within the framework of the culture of adult people in the 20th century has been influenced by the adoption of a number of cultural phenomena and it has brought about the widening of formal as well as content parts of the folklore. As a result, the children's literary tradltion includes not only literary forms which are conveyed verbally. Small literary works of scriptural culture are of the same validity and importance. All phenomena currently regarded as part of children's scriptural culture have their model in the culture of adult people. Those with the most stable content, form and function include, along with momente books and handwritten songbooks, also notebooks with quotations, naive poetry, short forms of humorous and amorous prose, and tests. They have mainly become the ownership of girls. The notebooks were established at the age of puberty, at the time of search for one's own attitude to love, friendship and the world. When selecting the texts the girls' notebooks maintained partial continuity with its predecessors - notebooks with quotations - anď they were based on them. Books and magazines became another source (again quotations, strophes of songs, naive poetry and tests). The text parts of notebooks included to a large extent paraphrases of authorship creations, their own texts as well as adopted naive poetry and prosaic work which were present in verbal or literary tradition. It is a question when this elemenl of children's culture came into being. Anyway, in the 1970s the notebooks of quotations, naive poetry, prosaic work and tests were already subject to tradition. They were copied, although they remaíned open to borrowed literary forms. The owners of notebooks, too, often used the collected texts as a pattern in another cultural element (such as text in a momento book, a love letter, etc.) or in another context (tests were, e.g., used in games). Girls' handwritten books have included naive poetry - short verses in letters, greetings and congratulations. Similarly to other texts in notebooks, these verses, too, constituted not only another gained "item" for the collectlon of texts, the girl liked, but they could also be used in correspondence. Sometimes they only existed in correspondence, witbout the support of the notebook. The presented verses are extractions from my collections from the early 1990 from the girls living in Prague and Vlašim. They were sorted into a selection which depicts the texts bound to the address, beginning of a letter, end of a letter, greetings and congratulations as well as letters written directly on thee envelope of a letter. The selection does not correspond with the authentic order or structure of texts of notebooks.

Skákání gumy v druhé polovině 90. let 20. století
Authors: Bittnerová Dana
Published: March 2024

The "Chinese jump rope" game is at a present a stable part of the repertoire of children's formalised games. It was born in the 1950s as another possibility of solving the discrepancy between a limited room for children's games in the city and their need of movement. In the given moment it was a novelty within the framework of "stationary-dynamic" games of children in the city. Just as its "elder sisters" from the city - such as games with the skipping rope, various ball games and hopscotch - it needed a special game requisite and it was constructed as a succession of increasingly difficult exercises. Just as in the case of other games, it was, too, given its place by the adults in the street, in a courtyard or on a playground. Due to this, the Chinese jump rope has been mainly played in warm months of the year. The presented portrait of a children's formalised game - the Chinese jump rope - is based on a field research carried out in 1997-1998. The information was provided by children - especially the girls from the first, second, third and fourth classes of elementary schools in Prague 1 and Prague 3 as well as three girls from the first class of an eight-year secondary school in Prague 9. A certain image of the state of the Chinese jump rope in the 1970s, which will provide certain comparisons, was obtained on the basis of a preparatory research conducted among ten women born in Prague between 1964 and 1966. At present the game "Chinese jump rope" is very popular, especially with girls. It gradually pushes aut from the current game repertoire other games such as skipping the rope or the ball games. At the same time the playing of the Chinese jump rope is accompanied with a significant variation process which proves that the life of this folklore phenomenon is still on a rise. A transmission and at the same time transformation of basic skipping combinations which often arise due to the bad practice - learning or forgetting a game (in connection with the limitation of the game to the warm months of the year) - leads to constant establishment of new and new variants. Moreover, the very structure of the game provides opportunities for innovations, for introduction of new elements into the game. The basic skipping combinations and subsequently skipping configurations are being widened on the one hand, but special skipping patterns are becoming independent on the other. The quality of folklore - to be syncretic - plays a role here, too. A number of skipping configurations is linked with texts of nursery rhymes and songs which provide rhythm to the skipping game. Last but not least, the Chinese jump rope as a requisite inspires children to create game schemes which only have a marginal or no relation with the original, initial Chinese jump rope.

Fenomén etnickej menšiny
Authors: Salner Peter , Luther Daniel
Published: March 2024

Using the example of Jewish community in Bratislava the paper deals with the problem of ethnic minority in the course of the 20th century. The selection of the locality is consistent with zhe multicultural nature of the environment under observation and its gradual transformation in the course of time. Statistical data have confirmed that there were numerous communities of ethnic Slovaks, Hungarians, Germans and Jews in the city. Their quantitative relationship, mutual relations as well as the position within Bratislava's hierarchy were changing depending on the political situation of the given state (Austro-Hungarian Empire, Czechoslovakia, wartime Slovakia, and the renewed Czechoslovakia) . The focus on the Jewish minority is a consequence of its specific and constantly changing position in society and the local community. The first part of the paper is devoted to methodological and theoretical aspects of the problem under observation. The authors submit various definitions of ethnic minority and changes in its legal position. They centered on the following phenomena: individual ethnic identity and its forming part of a group; differentiating function ot ethnicity; status of ethnic minorities; the minority status. The second part of the paper (subchapter Undifferentiated or differentiated minority) presents the knowledge acquired from an analysis of specific material about the Jewish community in Bratislava. The researchers examine the change in their position in the structure of the city, laying increased emphasis on the period after lhe Holocaust. The previous research of the problem under observation has proved that ethnicity is a factor of interna! aggression, through which various groups struggle for dominance in a community. The struggle has a polarizing character which was somewhat suppressed in tne Bratislava environment by tbe impact of several ethnic groups with their relevant importance. Their mutual interaction (expedient alliances or confrontations) mostly eliminated potential dominance of one of them. The situation changed after the dominant position in the city was gained by the Slovak communlty due to the political developments.
O slovenské „menšině" v Československém státě (1918-1938)
Authors: Barhoňová Vladislava
Published: March 2024

The paper deals with the question of relations between Czechs and Slovaks in the first, inter-war, Czechoslovak Republic (1918-1938). It is based on contemporary press, published in Bohemia and Slovakia. The basic question was a gradual political self-identification of Slovaks. It is presented by means of the attitudes of Hlinka's Slovak People's Party in 1923 (regional elections), the struggle for the rules of Slovak grammar (1933-rejection of their adaptation to the rules of Czech grammar), the Zvolen pact between the catholic Slovak People's Party anct the protestant Slovak National Party, the celebrations of the first Christian church in Slovakia (1933) and the declaration of Slovakia's autonomy (1938). To conclude: in 1918-1938, during the existence of the first Czechoslovak Republic, there was no Slovak minority. The first Czechoslovakia was de facto a multiethnic country, though officially it was designed as a country of Czechs and Slovaks, who had the will to create a single, Czechoslovak nation. The notion "minority" in the name of the paper is meant ironically and is to point to the approach often applied by Czechs for Slovaks.
Miesto sociokultúrnej skupiny v urbánnom prostredí
Authors: Koštialová Katarína
Published: March 2024

The way of life and the nature of culture in Zvolen was determined at the close of the 19th century by a diverse number of distinctive ethnic, religious, social and professional groups. Starting the 1870s the life in the town was increasingly influenced by railwaymen. The presented paper deals with the position of this professional group and its importance in the development of Zvolen's cultural activities between 1872 and 1938. The employees of Zvolen railways were ethnically differentiated. Under the Austro-Hungarian Empire the whole management and all senior posts were occupied by Hungarians. Slovaks mostly held the posts of craftsmen and workers. Many of them were farming factory-workers, originating in Zvolen and surrounding villages who farmed their own land. At the time of Czechoslovakia the number of railwaymen in Zvolen increased thanks to the construction of new railway networks. Qualified Czech experts came to the town. Relations between Slovaks and Czechs were friendly. Conflicts were quite exceptional. Given their firm position in the social and economic sphere, their social benefits and cultural activities, railwaymen as a professional group enjoyed high social prestige in Zvolen's urban society. They created a significant, internally heterogeneous social group. Depending on their position, they created Acastes. Everyone was aware of his social status. Clearly defined internal rules of behavior (hierarchy of respect, clothes, places of meeting, cultural activities, intergenerational cultural exchange, etc) were observed not only at work, but also outside it. Nevertheless, outwardly they assumed a unified position. The solidarity was reflected in their own association life (engine drivers associationB1903, foodstuff cooperativeB1907, association of railway firemenB1921, construction cooperativeB1922, music associationB1930). However, this had also an impact on the town's social life (organizers of parties, trips, sports events, participants in various types of entertainment, social activities, work with close groups from similar social environment, organization of parties of the town's middle class). With their contacts, which crossed the bounds of the town, the railwaymen mediated cultural information to the urban society and were bearers of new cultural trends.
Meziválečná americká sociologie v obrazech
Authors: Nešpor Zdeněk R.
Published: March 2024

The author presents fifteen photographs from the private album of Otakar Machotka (1899–1970), taken of prominent American sociologists and social scientists hailing from the interwar era. Machotka was one of the key personalities of Czech sociology in the given period, striving for its empiricization and internationalization, while at the same time he was an excellent expert on American and French sociology. He published a study on American sociology (1937) based on a research stay in Chicago and Los Angeles (and on his travels throughout the United States) in 1934–35. The photographs, which are published here for the first time, were taken at the same time. Although for methodological reasons we cannot consider them a sociological resource in the full sense, they provide interesting insight into the elite of the field at the time. The portraits are accompanied by short biographies, written by the publisher.

Výšivky z venkovských kostelů 17. a 18. století
Authors: Novotná Hedvika
Published: March 2024

Ke konci minulého století se dostávaly do muzeí pokrývky z hnědého lněného plátna, na první pohled s konzervativnější výšivkou, než bylo v té době v lidovém prostředí běžné. Velmi dlouho nebylo jasné, k čemu vlastně sloužily. Podle starých kostelních inventářů se zjistilo, že to byly převážně pokrývky na oltář. DO venkovských kostelů bývaly darovány ve zlomových životních situacích, ale také po válečných katastrofách či po změně konfese, když bylo nutné kostely znovu vybavit liturgickými rouchy. Tehdy se také drahé tkaniny v chudobě napodobovaly výšivkou barevným hedvábím na plátně.

Heteronomie und Entfremdung
Authors: Rivero Gabriel
Published: March 2024

New approaches to the concept of alienation propose to understand alienation as a kind of heteronomy and to establish a connection between Kant’s and Marx’ philosophy. This paper explores Kant’s understanding of alienation and shows, with help of Kant’s Reflexionen, that he exclusively conceives the term “entfremden/Entfremdung” within the meaning of the legal concept of “Veräußerung”. When interpreting “Entfremdung” as “Veräußerung” instead of “heteronomy”, similarities emerge between Kant’s and Marx’ thought, which manifest in the Kantian figure of the locator and the Marxian worker.
Experimental investigation on strengthening lap joints subjected to bending in glulam timber beams using CFRP sheets

Published: March 2024

Strengthening the carpentry joints is considered a big challenge for designers to maintain the joined timber elements’ load transfer and integrity. This research work investigates different techniques to strengthen the lap joints in glulam timber beams using carbon fiber-reinforced polymer (CFRP) sheets. For this purpose, 12 specimens of glulam timber beams were tested using the four-point loading method. One of the glulam timber specimens was an intact nonlapped specimen, and the others were lapped at mid-span using half-height lap joints. The lap joints were strengthened using different configurations of the CFRP sheets. The test variables were the clamping scheme, bond length, and reinforcement ratio of the CFRP sheets. The analysis of the test results indicates that the CFRP strengthening configuration could be more effective in strengthening the lapped glulam timber beams when the reinforcement ratio of the longitudinal CFRP sheets was equal to 0.303%, and the wrapping CFRP sheets continued beyond the lapped joint by a distance equal to the beam height. Such a strengthening configuration could succeed in increasing the effective stiffness and ultimate load of the lapped timber specimen to 109 and 110%, respectively, relative to those of the intact nonlapped specimen. Moreover, the results reveal that increasing the length or the reinforcement ratio of the longitudinal CFRP sheets without increasing the width of the wrapping CFRP sheets could not succeed in achieving the required improvements in the structural behavior of the lapped timber beams.
Cinnamic acid, a natural plant compound, exhibits neuroprotection in a mouse model of Sandhoff disease via PPARα
Authors: Raha Sumita , Paidi Ramesh K. , Dutta Debashis , Pahan Kalipada
Published: March 2024

Tay-Sachs disease (TSD) and its severe form Sandhoff disease (SD) are autosomal recessive lysosomal storage metabolic disorders, which often result into excessive GM2 ganglioside accumulation predominantly in lysosomes of nerve cells. Although patients with these diseases appear normal at birth, the progressive accumulation of undegraded GM2 gangliosides in neurons leads to early death accompanied by manifestation of motor difficulties and gradual loss of behavioral skills. Unfortunately, there is still no effective treatment available for TSD/SD. The present study highlights the importance of cinnamic acid (CA), a naturally occurring aromatic fatty acid present in a number of plants, in inhibiting the disease process in a transgenic mouse model of SD. Oral administration of CA significantly attenuated glial activation and inflammation and reduced the accumulation of GM2 gangliosides/glycoconjugates in the cerebral cortex of Sandhoff mice. Besides, oral CA also improved behavioral performance and increased the survival of Sandhoff mice. While assessing the mechanism, we found that oral administration of CA increased the level of peroxisome proliferator-activated receptor α (PPARα) in the brain of Sandhoff mice and that oral CA remained unable to reduce glycoconjugates, improve behavior and increase survival in Sandhoff mice lacking PPARα. Our results indicate a beneficial function of CA that utilizes a PPARα-dependent mechanism to halt the progression of SD and thereby increase the longevity of Sandhoff mice.

Carbon fiber-reinforced polymer (CFRP) exhibits aging effects over time that can degrade its mechanical properties. In this study, a systematic investigation was carried out to investigate the effect of distilled water aging on the mechanical properties of CFRP composite patch bonded on Al 2024-T3 plates. We built a finite element model to analyze the effect of water absorption by the composite and the adhesive on the effectiveness of the composite patch repair. Using the experimentally evaluated mechanical properties of CFRP and Araldite adhesive subjected to distilled water immersion, finite element simulations were validated. The experimental observations deduce that there was a negligible effect of moisture absorption on the bulk mechanical properties of CFRP and adhesive over time. However, a significant effect of moisture absorption was observed on the elasto-plastic behavior of both CFRP and adhesive. Consequently, the numerical simulations suggest that the moisture absorption reduces the bonded composite patch repair efficiency attributed to an increase in the plasticity around the crack front and accordingly increases the damage in the adhesive layer. This study attempts to provide guidelines on the severity of damage caused by water absorption on the performance of structures repaired with composite patches.

Our previous studies have shown that early exercise intervention after stroke increases neural activity and synaptic plasticity and promotes the recovery of nerve fiber bundle integrity in the brain. However, the effect of exercise on the repair of myelin in the brain and the related mechanism are still unclear. In this study, we randomly divided the rats into three groups. Before and after 28 days of intervention, body weight, nerve function, the infarct size, white matter fiber bundle integrity, and nerve myelin structure and function were observed by measuring body weight, analysis of modified neurological severity score, CatWalk gait analysis, MRI, luxol fast blue staining, immunofluorescence, and transmission electron microscopy. Changes in the expression of proteins in the MEK/ERK pathway were assessed. The results showed that early exercise intervention resulted in neurological recovery, decreased the infarct volume and increased nerve fiber integrity, the myelin coverage area, myelin basic protein (MBP) fluorescence intensity expression, and myelin thickness. Furthermore, the expression level of MBP was significantly increased after early exercise intervention, while the expression levels of p-MEK1/2 and p-ERK1/2 were significantly reduced. In the cell study, MBP expression levels were significantly higher in the oxygen and glucose deprivation and administration group.In summary, early exercise intervention after stroke can promote myelin repair by inhibiting the MEK/ERK signaling pathway.
Approaches for Quantifying the ICC in Multilevel Logistic Models: A Didactic Demonstration
Authors: Devine Sean , Uanhoro James O. , Otto A. Ross , Flake Jessica K.
Published: March 2024

Multilevel modeling techniques have gained traction among experimental psychologists for their ability to account for dependencies in nested data structures. Increasingly, these techniques are extended to the analysis of binary data (e.g., correct or incorrect responses). Despite their popularity, the information in logistic multilevel models is often underutilized when researchers focus solely on fixed effects and ignore important heterogeneity that exists between participants. In this tutorial, we review four techniques for estimating and quantifying the relative degree of between-person variability in logistic multilevel models in an accessible manner using real data. First, we introduce logistic multilevel modeling, including the interpretation of fixed and random effects. Second, we review the challenges associated with the estimation and interpretation of within- and between-participant variation in logistic multilevel models, particularly computing the intraclass correlation coefficient (ICC), which is usually a first, simple step in a linear MLM. Third, we demonstrate four existing methods of quantifying the ICC in logistic multilevel models and discuss their relative advantages and disadvantages. Fourth, we present bootstrapping methods to make statistical inference about these ICC estimates. To facilitate reuse, we developed R code to implement the discussed techniques, which is provided throughout the text and as supplemental materials.

This study uses glass substrates to create nanostructured TiO2 thin films employing SolGel method. Afterwards, TiO2 films are annealed in air for two hours at (400, 450, and 500) °C. The XRD tests demonstrate that all films are tetragonal polycrystalline and have orientations equal to those described in the literature. These findings suggest that when the annealing temperature rises, grain size increases. As the annealing temperature is raised, the Full Width at Half Maximum (FWHM) reduces from 0.57° to 0.0.51°, and the dislocation density drops from 45.22 to 39.22.18 nm, respectively. AFM has examined the thin films' surface morphology. The films formed using this method have good crystalline and homogenous surfaces, according to AFM tests. With an increase in annealing temperature, thin films' average particle size, average roughness, and Root Mean Square (RMS) value all drop. The films' optical characteristics. The transmission was over 97% decreased with increasing annealing temperatures. It is found that the band gap decreases from 3.42 to 3.3 eV with increasing annealing temperature. Between 300 and 900 nm, the films' refractive indices range from 2.89 to 2.2.76. With higher annealing temperatures, the films' extinction coefficients fall.

The risk of adverse short- and long-term outcomes (myocardial infarction, stroke, major bleeding, cardiovascular and non-cardiovascular death) was significantly increased in anemic patients even with a slight decrease in hemoglobin according to WHO criteria (less than 130 g/lfor men and less than 120 g/l for women). But majority of patients were not fit with the criteria of light grade of anemia according federal clinical guidelines (hemoglobin 90-110 g/l). The influence of anemia on outcomes becomes the most significant 12 months after PCI.

Published: March 2024

Growing construction industry boost cement manufacturing industry which consume a large amount of natural resources and releases greenhouse gases during cement production affects the environment. A lot of researchers attempt to find alternatives in integrating waste into concrete mixes and can be reused in cementitious construction material. Seashells are one of the waste materials that would give harm to their own biodiversity as it would occupy the landfills and seashores. Seashell is known to be very hard and protective on the outer layer produced by an animal that lives in the sea. This review paper is focused in using seashells as cement replacements in construction material. This academic review paper examines the potential of utilizing seashells, including various types such as a cockle, clam, oyster, and scallop as a sustainable and environmentally beneficial alternative to traditional usage in construction. By exploring the practical applications and economic viability of seashell-based concrete, this research aims to contribute to the broader discourse on eco-friendly construction practices and sustainable resources utilization in the construction industry.

Published: March 2024

Post-COVID-19 has strongly impacted the construction industry worldwide; many parties took alternatives to facilitate the relatively overdue work arrangements. The Malaysian construction industry has been directly affected and has had to increase the adoption of One-Stop Centre (OSC) electronic submissions. According to the Malaysian online system submission policies, it is necessary to obtain construction approval from the OSC through the implementation by town councils. Not understanding the process and documents involved in this procedure might result in ineffective submissions. Hence, the study objectives are to identify: 1) The current submission process and documents for construction approval to town councils, and 2) Issues related to the e-submission process. Semi-structured interviews were conducted with individuals from twenty town (20) city councils in Malaysia to achieve those objectives. The results indicate that the general process includes submitting the required documents through the OSC, validation of submittals, and meeting approvals. The required documents include planning permissions, drawings, engineering plans, environmental management plans, landowner documents, and approvals by other government agencies. Finally, the issues with the e-submission include technical problems and the lack of experience of all involved stakeholders. These findings can be used by policymakers to improve the submission system and industry practitioners in acquiring construction approvals.

Authors: Lin Lijin , Ting Irene Wei Kiong , Roslan Siti Zur Aainaa , Asif Jawad
Published: March 2024

This study examined how various dimensions of employee engagement influence the social sustainability of firms operating within the Malaysian construction industry. It focused on employees working in construction firms registered with the Construction Industry Development Board (CIDB) within the Federal State of Kuala Lumpur and Putrajaya. Simple random sampling was used for respondents selection followed by the distribution of an online questionnaire created using Google Forms. The data was analysed using Structural Equation Modelling via SmartPLS. The results indicated a favorable impact of behavioral employee engagement to firm social sustainability. In a broader sense, these findings shed light on the strategies required to enhance employee engagement for the sake of firm sustainability within the construction sector. It offers valuable insights into the leadership of construction organisations, specifically emphasising the significance of firm social sustainability and how it is influenced by employee engagement. A distinctive feature of this study is its segmentation of employee engagement into cognitive, behavioral, and emotional dimensions. Additionally, it addresses an aspect of sustainability that has received comparatively less attention—construction-related social sustainability—thus contributing to a more comprehensive understanding of the subject when compared to existing research.

This thesis explores the intricate relationship between urban air pollution, economic growth, population dynamics, and energy consumption. Addressing impacts on climate change, biodiversity, agriculture, and human health, it emphasizes compromised urban air quality due to pollution sources such as power generation, vehicle traffic, and construction. Key pollutants like particulate matter, carbon dioxide, sulfur dioxide, and nitrogen dioxide pose significant health risks. The study identifies road transportation as a primary contributor, underlining alarming statistics from WHO on global air quality, particularly impacting low-level socio-economic regions. Legislations and policies dating back over a century form the foundation for global air pollution control efforts. The research highlights innovative solutions like urban green spaces, smart traffic management, and renewable energy investments. It stresses the importance of public transportation, electric vehicles, clean construction practices, and initiatives to reduce industrial emissions. In response to challenges, the thesis proposes a comprehensive mitigation plan covering strategy such as promoting public transport, energy conservation, recycling, and afforestation. It outlines a way forward, emphasizing integrated urban planning, public awareness campaigns, government policies, and international collaboration. In conclusion, the thesis calls for collective responsibility to address urban air pollution's adverse effects on public health and the environment. The proposed roadmap aims to create sustainable, resilient, and healthier urban environments through a holistic and collaborative approach.

“Cassius Dio, A Bithynian ‘exiled’ to Rome?”
Authors: Freyburger-Galland Marie-Laure
Published: March 2024

First, we will retrace the life and brilliant career of this Roman senator of Bithynian origins who came from an ancient family of public figures and who had served five or six emperors and been friends with several of them, having been twice appointed to the role of consul.

Then we will consider the nature of his role as Senator coming from an Eastern province and its relationship with Roman power. We will come to see that he represents the perfect example of his theory of the association of provincial élites coming to power, which was developed at length in his work, Roman History, which he produced in Greek for a Greek readership.

Finally, rather paradoxically, we will consider how he sees himself in a largely bi-lingual and bi-cultural empire and how he speaks of his homeland with a view to determining whether his attachment to his ‘little country’ is the stronger and if his numerous sojourns in Rome amount to little more than a ‘golden exile’ for him.
Spatial and spiritual exile in Vergil's Aeneid
Authors: Walker Henry John
Published: March 2024

For Homer, Cicero, and Ovid, exile is equivalent to death, or even worse. Vergil's Aeneas is torn between his old homeland of Troy and the new home he must create in Italy, but he overcomes his nostalgia. Aeneas is consoled by the Stoic doctrine that he is obeying Fate, which governs the entire world, and by the Cynic view that he can carry his true self and identity with him anywhere he goes. In Book 6 of the Aeneid, he is given a revelation about reincarnation that is based on the Republics of Plato and Cicero. This teaching that all of life is an exile from heaven contrasts sharply with the worldly mission of conquest that Aeneas must follow in Italy. Vergil's sympathies lie with the exile rather than the conqueror.

Acinetobacter spp. are often isolated from natural sources, but knowledge about their presence in wild animals is fragmented and uncomplete. The present study aimed to characterize a series of Acinetobacter radioresistens isolated from Humboldt penguins (Spheniscus humboldti). Fifteen Humboldt penguins from an inhabited northern Peruvian island were sampled. Microorganisms were identified by MALDI-TOF MS. Antibiotic susceptibility to 12 antimicrobial agents was established, and clonal relationships were determined. A representative isolate was selected for whole genome sequencing (WGS). A. radioresistens were isolated from the feces of 12 (80%) Humboldt penguins, being susceptible to all the antimicrobial agents tested, except eight cefotaxime-intermediate isolates. All A. radioresistens were clonally related. WGS showed that the isolate belonged to ST1972, the presence of two chromosomal encoded carbapenemases (blaOXA-23 and a putative subclass B3 metallo-β-lactamase), and a series of point mutations in antibiotic-resistance related chromosomal genes, which were considered as polymorphisms. In addition, a few virulence factors, including a capsule-encoding operon, superoxide dismutases, catalases, phospholipases and a siderophore receptor were identified. The present results suggest that A. radioresistens may be a common member of the gut microbiota of Humboldt penguins, but further studies in other geographical areas are needed to establish this finding.
Szövegalkotó mesterséges intelligencia a társadalomtudományi felsőoktatásban: félelmek és lehetőségek

Tanulmányunkban azt vizsgáljuk, hogy az olyan generatív
mesterségesintelligencia-eszközök (GMI-eszközök), mint a ChatGPT vagy a Google
Bard, milyen hatást gyakorolnak a felsőoktatás szereplőire, elsősorban a
bölcsészet- és társadalomtudományok területén. A témával foglalkozó legfrissebb
szakirodalom áttekintésével kiegyensúlyozott képet alakítunk ki használatuk
lehetséges előnyeiről és kockázatairól. A GMI-eszközök elterjedése az
automatizálás új korszakának beköszöntét jelzi, amelyben a korábban
tudásmunkások által végzett feladatok jó részét gépekre bízzuk. Ez az átalakulás
a felsőoktatásban a hatékonyság javulásához és a hozzáférés demokratizálódásához
vezethet, de etikai kérdéseket is felvet, és veszélyezteti a tudományos
közösségen belüli bizalmat. Álláspontunk szerint a felsőoktatás
kulcsszereplőinek transzparens kommunikációt kell folytatniuk a GMI-k várható
hatásairól, hogy minél gyorsabban kialakíthassák a helyes használatuk
kultúráját. A tanulmány elkészítéséhez nem használtunk fel semmilyen
GMI-alkalmazást.
