Structure and oxygen evolution reaction performance of Ni-supported catalysts based on steam-exploded poplar
Authors: Yuan Junxia , Li Xiaofei , Wu Feifan , Pan Cheng , Yang Haitao
Published: June 2024

Using renewable steam-exploded poplar (SEP) as carbon source, nickel metal doped carbon hybrid materials were designed to synthesize catalysts (Ni/SEP) with certain oxygen evolution reaction (OER) properties and were compared with nickel catalysts supported on metal organic framework structure (ZIF67-Ni). The roles of SEP support in Ni-based catalyst were considered. Scanning electron microscope (SEM) images confirmed that the fiber could better hinder the aggregation of metal particles. Fourier transform infrared spectroscopy (FT-IR) indicated the presence of surface OH groups after the reduction process. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) analyses confirmed the major form of metallic Ni in the resulting Ni catalysts. Carbon materials as carriers, the synergetic effect of Ni-doped, and carbon carrier played an important role in facilitating the kinetics of OER, which was similar to the carrier of metal-organic frame material. Notably, the Ni/SEP (11.3 mF/cm-2) and ZIF67-Ni (37.2 mF/cm-2) with better OER performance exhibited a smaller double layer capacitances (Cdl), suggesting the intrinsic OER catalytic activity of the Ni/SEP and ZIF67-Ni were much higher in comparison to the ZIF67-Ni/SEP. Moreover, the inferior performance of Ni/SEP further indicated that the synergistic effect between carbon and Ni/NiO contributes to the enhanced OER activity.

Published: June 2024

In 2020, the US Food and Drug Administration approved liraglutide (glucagon-like-peptide-1-receptor-agonist) as an adjunctive therapy for weight management in adolescents aged 12 to 18 years in combination with a reduced-calorie diet and increased physical activity. The 2023 American Academy of Pediatrics guidelines recommend pharmacotherapy with glucagon-like-peptide-1-receptor-agonist as a second-line therapy in obesity management. Although reports in adults have suggested a link between liraglutide and adverse effects including hepatic injury and acute kidney injury (AKI), these effects have not previously been reported among adolescents treated with liraglutide for weight loss. We present a 17-year-old male who developed AKI and evidence of hepatic injury (significant elevation of hepatic transaminases) after 3 months administration of the lowest dosage of liraglutide (0.6 mg/day) for management of class III obesity. The patient experienced significant loss of appetite, weight loss, and melancholy during the treatment period. One month after discontinuing liraglutide, his mood had improved, his liver enzymes had returned to normal, and AKI had resolved. The Adverse Drug Reaction Probability Scale suggested a high likelihood of a causative association between liraglutide and his symptoms. Our report highlights the importance of vigilance in monitoring for these potential adverse effects among adolescents treated for obesity with any dose of liraglutide.

Published: June 2024

Cycloramphus boraceiensis is an endemic frog of the Atlantic Forest of southeastern Brazil. Although relatively easy to find and distributed over a well-sampled region in southeast Brazil, little is known about its natural history, breeding activity, and vocal repertoire. In the present study, we provide new information on pre-and post-hatching larval development, describe new traits of their advertisement calls, describe its aggressive call for the first time, and provide new data about adults’ and tadpoles’ defensive strategies. We found individuals on rocks on cascaded streams or within rocky crevices along streams inside forested habitats. Males concentrated their calling activity between 03:00 and 5:00 h and between 19:00 and 23:00 h. The aggressive call is shorter than the advertisement call and has greater variation in the number of pulses and emission rate. The eggs hatched at Gosner’s stage 25, after seven and eleven days of oviposition, and tadpoles took between eight and ten days to complete metamorphosis. This study contributes to the knowledge of the Flattened Waterfall Frog by filling natural history gaps that can be useful for species conservation and bringing attention to traits that still need further investigation, such as color plasticity and microhabitat selection.

Authors: Vallejo Sandra Viviana , Rojas Andrés Mauricio , Linnakoski Riikka , Osorio Jhon Alexander
Published: June 2024

Endophytic fungi are well known for their association with a wide variety of plant species, likewise, mangrove plants are well known for harboring a vast variety of fungi with a valuable diversity of bioactive compounds originating from the secondary metabolism that is synthesized in part as a response to the chemical defense against microorganisms, hostile environments, and antagonistic insects. The objective of the present study was to analyze the chemical composition of endophytic fungi isolated from mangrove trees in Buenaventura, Colombia. Analyses of DNA sequences from the internal transcribed spacer ribosomal nuclear region (ITS) were conducted to determine the fungi’s identity. The results revealed 17 isolates, belonging to eight fungal families. All isolates were subjected to thin-layer chromatography analysis, observing different phytochemical nuclei eluted in the system (7: 3 hexane: acetone), of these, 23 compounds were recognized using gas chromatography coupled to mass spectrometry; cytotoxicity tests were carried out in human foreskin fibroblast cell line, which did not show a trend in cell viability. The selected endophytic fungi derived from mangrove trees reveal the presence of different chemical compounds, representing an alternative resource of great interest in bioprospecting and bioremediation.

Published: June 2024

El estudio plantea la utilización de un modelo jerárquico basado en la ratio de capacidad de pago, definido como la relación de los resultados operativos con las deudas, para la predicción de insolvencia en un contexto turbulento como la economía argentina. Las técnicas aplicadas para la construcción de los modelos son el análisis discriminante y árboles de clasificación. La evidencia indica que el modelo de capacidad de pago en dos momentos en el tiempo supera al modelo Z-score calibrado, aplicando el método de análisis discriminante lineal como el de árboles de clasificación, si bien este último mostró ser superior.
Entre las ansiedades fronterizas y un sello oligárquico compartido: los gobiernos de Colombia frente a la dictadura de Juan Vicente Gómez en Venezuela, 1908-1935.
Authors: Flórez Bolívar Francisco Javier , Mercado Cabana Ricardo , Rhenals Doria Ana Milena
Published: June 2024

Entre 1908 y 1935, en el marco del ascenso y consolidación de Venezuela como principal exportador de petróleo a nivel global, el político y militar Juan Vicente Gómez dio forma a un régimen dictatorial. Este artículo, a partir de los recursos analíticos provenientes de las historias conectadas, pretende analizar las posiciones políticas y diplomáticas asumidas por los gobiernos de Colombia frente a la dictadura impuesta por Gómez en territorio venezolano. A través de la revisión de prensa e informes del Ministerio de Relaciones Exteriores, se muestra que, durante el régimen gomecista, los gobiernos colombianos mantuvieron relaciones diplomáticas con Venezuela y algunos de ellos colaboraron con Gómez para controlar los alzamientos armados organizados por militares venezolanos desde Colombia. Esta posición de los gobiernos colombianos estuvo determinada por el rol clave que Venezuela jugaba en la solución de varios problemas fronterizos afrontados para entonces por Colombia. Aparte de diferendos fronterizos con la misma Venezuela, los gobiernos de la época tuvieron que lidiar con rumores separatistas de territorio colombiano en la frontera colombo-venezolana y tensiones diplomáticas con Ecuador.
Un espacio comercial entre el Caribe y el corazón de la selva: las redes comerciales de los árabes en el Chocó, Colombia, 1900-1930
Authors: Díaz-Rico Jhojan-Alejandro
Published: June 2024

este artículo reconstruyó las redes comerciales que desarrollaron los inmigrantes árabes para movilizar sus mercancías desde Cartagena, principal puerto de llegada a Colombia de las importaciones de estos comerciantes, hasta Quibdó y poblaciones de los ríos Atrato y San Juan entre 1900 y 1930. Mediante el análisis de redes sociales se estudió la estructura interna de la red. Posteriormente, se describieron las rutas de distribución por donde esta operaba para comprender el papel de la geografía en su funcionamiento. Se demostró que gracias a un escenario de expansión comercial posibilitado por el auge de extracción de platino, y a una compleja red de distribución y venta de mercancías que se construyó mediante relaciones de parentesco, paisanaje y vínculos con grandes y pequeños comerciantes colombianos, los árabes lograron establecer un control comercial de venta de mercancías importadas y de exportación de productos naturales en el alto Atrato, lo que les permitió expandir sus redes comerciales hasta las poblaciones mineras del alto San Juan. Se concluyó que la geografía cobró un papel central en dicha expansión, pues los ríos se convirtieron en autopistas a través de las cuales se exportó el platino e ingresó la modernidad al Chocó.

Published: June 2024

Dissolved gas chromatography (DGA) analysis and Megger DC insulation tests are performed to diagnose the condition of a power transformer. In this context, the objective of this study is to assess whether there is a relationship between both types of tests. To this effect, a database with DGA and Megger DC test protocols is analyzed, using the theory of variable correlation as well as current DGA techniques. The results allow stating that there is indeed a relationship between both tests under specific conditions. Therefore, the DC isolation status of a transformer can be estimated via DGA tests.
The Formalism of Chemical Thermodynamics Applied to an Oscillatory Multistep Chemical System
Authors: Montoya Jean P. , Contreras-Payares Alexander , Barragán Daniel
Published: June 2024

The thermodynamic optimization of a process focuses on consumption, production, and efficient use of energy. The unsteady-state nature of batch reactor processing requires describing the set of processes’ dynamic behavior for energy optimization. This work aims to apply the formalism of chemical thermodynamics to a multistep chemical system in a batch reactor, aiming for a dynamic description of its evolution to the equilibrium state. As the system of study, we selected a mathematical model called the Oregonator, derived from the mechanism of the oscillating Belousov-Zhabotinsky reaction. In the methodology, we used the reaction quotient to evaluate the Gibbs function, the thermodynamic affinity, and the entropy generation as a function of the reaction extent. The results show that the overall reaction fulfills the thermodynamic fundamentals of chemical equilibrium, despite having a non-stoichiometric coefficient. However, the multistep coupled reaction system does not allow verifying compliance with the thermodynamic foundations of chemical equilibrium. We conclude that it is necessary to improve thermodynamic formalism to describe multistep chemical processes as a function of a global reaction extent variable. In this scenario, the entropy production rate emerges as a promising quantity.

Published: June 2024

Introduction: Lack of physical activity and high obesity rates in children and adolescents are major public health concerns. Active school transport is a strategy that can contribute to achieving recommended physical activity levels.
Objective: To determine the relationship between the use of active school transport by children from the Colombian Caribbean region and their parents’ perception of barriers to active school transport.
Materials and methods: Cross-sectional study conducted in 2019 with data from 3 067 primary school children from the Colombian Caribbean region. Data were obtained by administering an ad hoc questionnaire (questions on how children commuted to school and about their academic and sociodemographic characteristics) and the Active School Transport Barriers scale to the parents or legal guardians of the children. A multivariate logistic regression analysis was performed in which Odds ratios (OR) and their respective 95% confidence intervals (95%CI) were calculated to determine the relationship between the modality of transportation to school (active/passive) and the barriers to active school transport perceived by the students’ parents.
Results: A total of 51.3% of the schoolchildren actively transported to school. Factors such as considering that the roads are not appealing (OR=1.64; 95%CI: 1.39-1.94), that there are dangerous road crossings on the route (OR=1.29; 95%CI: 1.1-1.54), that the distance between home and school is very long (OR=1.83; 95%CI: 1.5-2.1), and that the traffic on the route is heavy, (OR=1.5; 95%CI: 1.2-1.8) increased the probability of passive transportation (i.e., using motor vehicles).
Conclusion: In the present study, long distances between home and school, aesthetics of roads, heavy traffic on the route, and insecurity of road crossings, among others, were identified as barriers to the use of active school transport.

How can nature and nurture influence teleworkers: The influence of national culture and personal traits on job satisfaction
Authors: Táborosi Srdana , Rajković Avdija Jelena , Poštin Jasmina , Terek Stojanović Edit , Berber Nemanja , Nikolić Milan
Published: June 2024

The paper presents the results of research on the impact of national culture, Big Five personality traits, and emotional intelligence on job satisfaction in teleworkers. The impacts were also examined in conventionally employed, which enabled a comparison. The research was conducted in the countries of the Western Balkans and included 313 respondents. The job satisfaction of teleworkers is most positively influenced by humane orientation, performance orientation, agreeableness, conscientiousness, openness, self-regulation, and social skills. Self-awareness can act both positively and negatively, and neuroticism has a negative impact on job satisfaction. National culture has a greater impact on job satisfaction among conventionally employed rather than within teleworkers. Big Five personality traits work differently: extroversion has a greater impact on job satisfaction among conventionally employed, while agreeableness and conscientiousness have a greater impact on job satisfaction among teleworkers. Emotional intelligence has a greater impact on job satisfaction among conventionally employed rather than teleworkers. Teleworking employees are less influenced by the environment, and thus less influenced by national culture. Emotional intelligence helps conventionally employed work more, while teleworkers place higher value on the results of their work.

Los micronúcleos pueden estar en todas las células que sufran división celular, estos son pequeños fragmentos de DNA nuclear ubicados erróneamente en el citoplasma, con grandes efectos pleiotrópicos. Son bioindicadores de genotoxicidad y promotores de inflamación, senescencia, apoptosis, inestabilidad y caos genético. El DNA micronuclear tiene el potencial de sufrir reorganización masiva y problemas de reparación, su membrana se rompe con facilidad y libera al citoplasma su contenido de DNA, esto estimula crónicamente al sistema inmunitario innato. El micronúcleo puede tener diferentes destinos como ser eliminado, permanecer en el citoplasma o ya reorganizado, incorporarse nuevamente al núcleo y generar inestabilidad y caos genómico, por introducir en un evento numerosas mutaciones; y así esta célula rápidamente se maligniza. Específicamente, las células micronucleadas del epitelio oral son un “sensor interno” temprano de susceptibilidad a la inestabilidad genómica, y si el 90% de todos los cánceres son epiteliales, entonces la mucosa oral ofrece una oportunidad única para monitorear a individuos en riesgo; incluso permite evaluar otros biomarcadores de genotoxicidad y citotoxicidad. Por ello, el objetivo de esta revisión es destacar causas y consecuencias de los micronúcleos, y su aplicabilidad en mucosa oral en la detección oportuna de individuos susceptibles a la inestabilidad genómica.

INVESTIGATIONS ON THE RELEASE OF HEAVY METALS DURING THE GASIFICATION OF SIMULATED WASTE WOOD
Authors: Siepmann Marcel , Yazhenskikh Elena , Müller Michael
Published: June 2024

In recent years, the energy demand has been continuously increasing. At the same time, fossil fuels
are being progressively replaced by renewables. However, this shift from fossil fuels such as coal to
renewable fuels like wood creates new challenges, as many industrial plants continue to rely on legacy
fuels. Unlike coal, the elements present in renewable resources can vary greatly. The differences are
influenced by a variety of factors. For example, waste wood can be contaminated by different additives
(paints, fire retardants, and others). To understand under which boundary conditions (e.g., temperature,
gasification atmosphere) the respective elements are bound in the ash/slag or released into the gas
phase, experiments with a molecular beam mass spectrometer (MBMS) with an upstream electrically
heated flow reactor were conducted. Pieces of clean wood were impregnated with various heavy metals
and examined under several boundary conditions (temperature and gasification atmosphere). Furthermore,
impregnated cellulose partly mixed with single ash components served as model fuel for detailed
investigations. Additionally, thermochemical equilibrium calculations were carried out. The results of
the experiments show that the release of some heavy metals (Cd, Pb, Sb, Sn, Zn) is very strong already
at low temperatures, while for others (Cr, Cu) no release can be detected even at high temperatures. The
corresponding thermodynamic equilibrium calculations comply with these findings. Since the process
management and preparation of the fuels can be adjusted accordingly, these results form an important
basis for planning gasification processes using waste wood as fuel.

Published: June 2024

This study investigates the double-diffusive convection onset in a nonuniformly rotating anisotropic porous fluid layer under the influence of Soret and internal heating effects. The linear stability approach is employed to investigate the system when subjected to infinitesimal perturbations. The nonlinear case is investigated using a minimum truncated double Fourier series, leading to the derivation of nonlinear Lorenz-type equations. As a novel characteristic of the article, the newly developed local linearization block hybrid method is utilized to solve the nonlinear Lorenz-type equations. We observed that the method achieves convergence and accurate results with a large number of collocation points. Heat and mass transfers have been expressed in terms of Nusselt number and Sherwood number, respectively. The study also investigates the influence of time-dependent rotation and internal heat generation on heat and mass transfer in anisotropic porous layers, including the Soret effect. Among other findings, we noticed that rotation modulation and mechanical anisotropy enhance the rate of heat and mass transfer, potentially advancing the onset of convection in the system. Further, the dual effect of internal heat generation is observed in the presence of the Soret effect.

Authors: Doğruyol Adnan , Şanver Cahit
Published: June 2024

The expenditures of the state throughout history have been documented. Today, a budget is a document prepared, approved and implemented according to certain rules for the future. Various budgeting principles must be followed in the modern state budget. Interestingly, it is known that the budget prepared during the reign of Tarhuncu Ahmet Pasha of the Ottoman Empire in the 16th century is similar to today's state budget. The purpose of this study is to determine whether the budget led by Tarhuncu Ahmet Pasha is a state budget in today's modern sense or what type of budget it is. Information and documents obtained from the Ottoman Archives were used in the study. It has been determined that the budget prepared by Tarhuncu Ahmet Pasha is compatible with the majority of today's budget principles and rules, although not all of them.
The Russian Orthodox Church and Moscow-the Third Rome Concept
Authors: Duali Ş. Muhammed
Published: June 2024

In 988, under the leadership of Kinyaz Viladimer, Russians accepted Christianity through the Patriarchate of Constantinople and entered a new phase in their history. With Christianity, the Russians were introduced to writing and, most importantly, to religious texts. At the same time, this religious conversion also led to the acceptance of the belief of chosenness, which had spread to Christianity from Judaism. Nestor, a Russian priest who lived in the 12th century, wrote in his work that although Russians were the last community to accept Christianity, they would undertake important missions in the future. He also attributed a mission to the Russian society by referring to the biblical passage that the feet will be the head and the head will be the feet. However, in the mentioned centuries, the Eastern Roman Empire was still the center of Orthodoxy. For this reason, the Russian Orthodox Church would remain for many years as a Metropolitanate under the Patriarchate of Constantinople. However, the increasing Ottoman pressure on Constantinople from the 1400s onwards created several historical opportunities for the Russians. In particular, the Byzantine agreement with the Pope of Rome in Florence in 1439 mobilized the Russian Church. Using this agreement as a pretext, Moscow severed its relations with Constantinople. In 1453, the Ottoman conquest of Constantinople, the center of the Orthodox world, opened a new page in Russian Theo-politics. Russian priests believed that Nestor's prophecy had been fulfilled and Moscow developed the concept of the Third Rome. Appearing in the 16th century, the Moscow-Third Rome concept soon became the ideological basis for the formation of the Moscow kingdom. In this article, the concept of Moscow Third Rome, which is one of the important turning points in Russian history, is analyzed through an analytical method. The background of the concept, the conditions that led to its emergence, its historical development and its reflections on the present day are emphasized.
BİST Ulaştırma ve Depolama Firmalarının Finansal Performansının DuPont Analizi Yöntemiyle Değerlendirilmesi
Authors: Özşahin Koç Filiz
Published: June 2024

Firma iç ve dış bilgi kullanıcıları (sahipler, yöneticiler, ortaklar, kredi kurum ve kuruluşları, yatırımcılar, çalışanlar vb.) firmayla ilgili doğru kararlar alabilmek için pek çok araçtan yararlanırlar. Bahse konu araçlardan biri de finansal analiz tekniklerinden oran analizi içerisinde yer alan DuPont Analizi tekniğidir. DuPont Analizi firmaların finansal performanslarının değerlendirilmesinde önemli bir analiz tekniğidir. Zira DuPont analizi firmalara öz kaynak karlılığının düşük veya yüksek olmasının sebeplerini sunmaktadır. Literatür araştırması neticesinde firmaların ve sektörlerin finansal performanslarını DuPont analizi ile inceleyen pek çok çalışma bulunmaktadır. Söz konusu çalışmaların ulaştırma, sağlık, çimento, yiyecek içecek ve tütün, teknoloji, imalat, finans, kırtasiye, tarım, turizm ve gayrimenkul yatırım ortaklığı sektörleri üzerine yapıldığı belirlenmiştir. Ancak literatür incelemesi sırasında, ulaştırma ve depolama sektörü ile ilgili BIST yıllık verilerini geniş kapsamlı inceleyen bir çalışmaya rastlanılmamış olması ve bu alandaki boşluğu tamamlaması çalışmanın önemini ortaya koymaktadır. Bu bağlamda çalışmanın amacı, BIST ulaştırma ve depolama sektöründe faaliyette bulunan firmaların finansal performanslarını DuPont Analizi ile incelemek ve sektöre özgü olarak elde edilen sonuçları değerlendirerek firmalara geleceğe yönelik alınması gereken tedbirler ve iyileştirme politikaları hakkında katkı sağlamaktır. Ayrıca hem iç hem de dış bilgi kullanıcılarının firmalar ile ilgili isabetli kararlar almasına yardımcı olmaktır. Bu amaç doğrultusunda, Borsa İstanbul (BIST) Ulaştırma ve Depolama Sektöründe faaliyette bulunan 9 firmanın 2018-2022 yılları arası verisi incelenmiştir. Firmalara özgü veriler Kamuyu Aydınlatma Platformu ve firmaların internet sitelerinde yer alan raporlardan elde edilmiştir. Çalışmada elde edilen veriler DuPont Analizi yöntemi kullanılarak değerlendirilmiştir. Bu bağlamda ulaştırma ve depolama sektörü için finansal performans bakımından en iyi olan yılın 2022 yılı olduğu belirlenmiştir. Öz kaynak karlılığı firma ortaklarının koydukları sermaye karşılığında ne kadar kâr elde ettiklerini, yani her bir birim sermaye karşılığında kaç birim kâr yaratıldığına yönelik ölçütlerden biridir. Dolayısıyla firmanın daha az sermaye ile daha fazla kar elde ettiğini göstermektedir. Bununla birlikte 2020 yılında yaşanan ve tüm dünyada pandemi olarak ilan edilen Covid-19 salgını neticesinde alınan tedbirler ve kısıtlamalarla birlikte özellikle hava yolu taşımacılığı yapan firmalarda öz kaynak karlılıklarının negatif yönlü olduğu bir başka ifadeyle o yıl zarar ettikleri bulgusu elde edilmiştir.

U opisima i ugovorima bilježi se njihovo kretanje i boravak u prostorima najvažnijih dubrovačkih crkava, kao i pristup crkvama iz javnog prostora. Arhitektonski elementi dodatno osvjetljavaju uporabu fragmentarno sačuvanih struktura, posebice galerije za plemkinje prigrađene uz dominikansku crkvu, koja je transformirala ne samo laički dio crkve, već i prilaz u javnom prostoru pred samostanom. U radu se, također, analizira socijalno raslojavanje ženske populacije po više kriterija, koje se očituje u specifičnom korištenju crkvenim prostorom

This study aimed to delve into the under-explored domain of early handwriting performance among Arabic-speaking kindergarten children, focusing on the potential factors influencing early handwriting competency. The research encompassed 218 children from diverse socio-economic backgrounds in Israel. The underlying skills assessed were divided into linguistic skills (phonological awareness and orthographic knowledge) and graphomotor and fine-motor skills. Hierarchical regression analyses were utilized to evaluate the contributions of these skills. Results indicated that, within the Arabic orthographic context, orthographic knowledge stood out as a paramount contributor to early handwriting performance, more so than phonological awareness. Furthermore, graphomotor and fine motor skills significantly influenced letter-copying speed and legibility, but not the accuracy of letter-writing to dictation. In conclusion, while orthographic knowledge is paramount, the importance of graphomotor and fine motor skills for early handwriting performance in Arabic cannot be understated. The study suggests that a focused approach to these skills can lead to more effective interventions and teaching methodologies tailored for Arabic-speaking kindergarteners.

Background: The use of antioxidants of natural origin is an alternative to improve the cryopreservation of sheep semen. Objective: To evaluate the effect of Erythrina americana diet supplementation in the seminal characteristics of rams. Methods: Ten rams were randomly distributed in two treatments: l) group with addition of E. americana (20% dry matter basis) in the diet (AEA, n=5), and 2) the control group without addition of E. americana (SEA, n=5). Both diets were balanced iso-proteinically and iso-energetically. The feeding period of the rams was eleven weeks. The ejaculates were obtained through an artificial vagina and were evaluated fresh (37 °C) and refrigerated (5 °C). Volume (VOL) was evaluated with a tube graduated in milliliters, sperm concentration (CON x106) with a photometer and mass motility (MM, 1-5), individual motility (IM), normality (N) and live sperm (L) by microscopic observation. Results: The fresh semen showed that the inclusion of E. americana in the diet of rams did not modify (p>0.05) the parameters of VOL, CON, MM, and N, but decreased (p<0.05) the IM and L. In refrigerated semen the variables L and N were not different (p>0.05) among the treatment groups; however, IM was improved by the AEA group (p<0.05) compared to the SEA group. Conclusion: The supplementation with E. americana in the diet of rams reduces the sperm quality in fresh semen but is beneficial in the cooling process for refrigerated semen.

Multiple methods have been developed to construct driving cycles. However, a procedure to verify the ability of those methods to construct driving cycles that accurately represent local driving patterns has yet to be established. In this manuscript, we propose a protocol that addresses this need. We first define driving pattern representativeness and then propose a procedure and metrics to evaluate it. We argue that driving cycles should also reproduce vehicles’ energy consumption and tailpipe emissions. i.e., driving cycles should be constructed in the way that fuel consumption and tailpipe emissions of a given vehicle technology following the driving cycle in a chassis dynamometer are similar to the values observed in the regular use of that vehicle technology in the region for which the driving cycle was obtained. Based on this statement, we include a procedure and metrics to evaluate the ability of the method under evaluation to fulfill these requirements.
“Tell Me who You Hang Out with and I'll Tell You Who You Are”: Analysis of How the Social Contacts´ Gender Predicts Self-Concept as a Socially Engaged Person and Intention of Future Social Participation Among Young People
Authors: Dávila María Celeste , Zlobina Anna
Published: June 2024

The purpose of this work was to study the effect of gender on the social influence processes that explain the young people’ social participation. A total of 962 Spanish undergraduate students completed a questionnaire assessing their likelihood of engaging in social participation in the future, their self-concept as socially engaged people, and the number of socially involved contacts in their social networks, distinguishing between male and female contacts. We found that gender homophily characterised the social networks of both women and men. Consistent with gender stereotyping, being female predicted self-concept and the intention to be civically engaged, and being male predicted the intention to be politically engaged. For both genders, the number of female contacts predicted the intention to be civically engaged only, and the number of male contacts predicted the intention to be politically engaged. Moreover, for males, having a more gender-heterogeneous social network predicted to a greater extent their self-concept as socially engaged. The findings provide new insights for targeting interventions designed to foster social participation in women and men.

Rad ispituje utjecaj outputa sustava visokog obrazovanja i različitih obilježja radnog okruženja na pojavnost nezadovoljstva među zaposlenicima na hrvatskom tržištu rada. Znanstveni se doprinos ogleda u dosad neistraženim efektima strukturnih promjena sustava visokog obrazovanja poput Bolonjskog procesa na pojavnost nezadovoljstva na radu te u upotrebi mjere nezadovoljstva oslobođene subjektivnosti – namjere promjene posla zaposlene osobe. U analizi koriste se podaci 91 045 na puno vrijeme zaposlenih osoba, prikupljeni za razdoblje od 2009. do 2019., a korištene metode uključuju logističku i probabilističku regresiju. Rezultati pokazuju da je procijenjena vjerojatnost nastupanja nezadovoljstva na radu viša za visokoobrazovane zaposlenike koji su visoko obrazovanje stekli u okviru Bolonjskog procesa u odnosu na one koji su visoko obrazovanje stekli prije uvođenja Bolonjskog procesa te za zaposlenike između 35 i 55 godina starosti. Višu vjerojatnost nastupanja nezadovoljstva na radu također pokazuju svi zaposleni koji sudjeluju u različitim programima usavršavanja, bez obzira na stečenu razinu obrazovanja, dok se rast produktivnosti još jednom pokazuje važnim prediktorom smanjene vjerojatnosti nastupanja nezadovoljstva.

Svrha je ovoga rada analizirati produkciju radova u polju ekonomije u Hrvatskoj na uzorku od gotovo 34 000 radova objavljenih od 2000. do srpnja 2023. te identificirati najčešće pojmove i njihovu povezanost. Preuzeta je i pročišćena baza podataka radova u polju ekonomije iz Hrvatske znanstvene bibliografije (CROSBI), obrađena je naprednim alatima umjetne inteligencije (GPT) i bibliografskim alatima (OpenRefine, VOSViewer) te je potom izdvojeno stotinu najčešćih pojmova iz naslova i ključnih riječi. Godišnja produkcija znanstvenih i preglednih radova porasla je u dva desetljeća oko četiri puta. Organizacija i menadžment dominantna je ekonomska grana u Hrvatskoj, a najveći porast interesa u promatranom razdoblju imale su grane kvantitativne ekonomije i ekonomike poduzetništva, dok su se najviše smanjili udjeli makroekonomije i međunarodne ekonomije. Turizam i marketing najpopularnije su teme. Značenje i doprinos ovoga rada ogledaju se u novim uvidima u hrvatsku ekonomsku znanost te nose implikacije za nositelje politika, ekonomske fakultete i istraživače.

Uvažavanje ekoloških, društvenih i upravljačkih čimbenika (ESG) u korporativnom poslovanju pojava je koja se naglašeno proširila u posljednjem desetljeću, uslijed osvještavanja važnosti brige za okoliš i klimu, za društveno odgovorno i održivo poslovanje te dodatno motivirano rastom interesa ulagača za takva ulaganja. Zbog snažnog širenja okolišno, društveno i/ili upravljački odgovornog i održivog poslovanja i ulaganja, javila se potreba i za njihovom konkretnijom regulacijom. Od navedenih čimbenika, najviše pozornosti dobio je najzastupljeniji, okolišni (E) aspekt poslovanja, koji je ujedno i najkonkretnije mjerljiv, dok su društveni (S) i upravljački (G) čimbenici u tom smislu ostali podređeni i manje zastupljeni. Ovaj rad usmjeren je na analizu obuhvata, problema mjerenja i učinaka društvenog čimbenika jer je ljudski kapital važan čimbenik poslovanja pa je uvažavanje interesa i odnos prema zaposlenicima, suradnicima, klijentima, dobavljačima te zajednici dio odgovornog i održivog poslovanja. Empirijsko istraživanje o primjeni čimbenika održivog i odgovornog poslovanja, uz poseban osvrt na društveni čimbenik u Europskoj uniji u financijskoj industriji te detaljniju analizu stanja u Hrvatskoj, temelji se na najnovije dostupnim podacima za 2021. i 2022. Komparativna analiza te prijedlozi iskazivanja i mjerenja čimbenika održivog i odgovornog poslovanja, sistematični prikaz razvoja i nadogradnje regulacije područja odgovornog i održivog poslovanja i ulaganja te rezultati analize relativne zastupljenosti i prihvaćenosti ESG čimbenika omogućili su zaključke o konkretizaciji potencijala implementacije i nadogradnje mjerljivog društvenog čimbenika na primjeru poslovanja društava za osiguranje.
User Clustering with Spatial Concept using Supervised Learning for NOMA Downlink
Authors: Hurianti Vidyaningtyas
Published: June 2024

This research aims to optimize the performance of Successive Interference Cancellation (SIC) in Power Domain Non-Orthogonal Multiple Access (PD-NOMA) technology by applying spatial concepts through the use of beamforming techniques. User clustering is a key element in achieving this goal, and this research applies various supervised machine learning classification algorithms including Decision Tree, K-Nearest Neighbors (K-NN), Support Vector Machine (SVM), Random Forest, Logistic Regression, and Naive Bayes. The experimental results show that Random Forest achieves the highest accuracy in classifying users, followed by Decision Tree. In addition, in measuring performance using ROC (Receiver Operating Characteristic) and AUC (Area Under the Curve) curves, Decision Tree and Random Forest achieved the best results as well. While in terms of experimentation process time, decision tree has a faster time than random forest. Overall, Random Forest and Decision Tree algorithms are suitable for the task of user clustering in the context of PD-NOMA which utilizes the spatial concept of user to Base Station (BS).
