Effect of the Students’ Test Anxiety Prevention Program on Students’ Experiences of Test Anxiety: A Mixed-Methods Experiment
Authors: Abdulbaqi Jvan , Uzun Gizem Oneri
Published: December 2024

This study aims to introduce the Students’ Test Anxiety Prevention Program (STAPP), an intervention for test anxiety for university students in Iraq. We also evaluated its effectiveness against test and state anxiety. The STAPP is a short three-session intervention program comprising expressive emotional dialog, psychoeducation, and educational and cognitive–behavioral therapy techniques. Numerous studies have shown the effectiveness of cognitive–behavioral techniques among other populations; however, most interventions in Iraq focus on posttraumatic stress disorder. In this explanatory sequential mixed-methods study, we used an experimental design in the quantitative phase and conducted a focus group discussion in the qualitative phase. The study was conducted among a sample of Iraqi university students, as there is scarce research on test anxiety interventions among the Iraqi student population. Convenience sampling was used to select 60 participants—35 women and 25 men—randomly assigned to the control or intervention groups. The test-retest approach was used to compare test scores and state anxiety for both groups. The focus group discussion included seven members from the intervention group. The results suggest that STAPP is effective in reducing test anxiety. However, no significant changes were observed in state anxiety in the post-test phase. State anxiety is transient, whereas test anxiety represents a persistent trait. Participants displayed elevated levels of state anxiety, which may be attributed to coronavirus disease 2019-related stressors. Intervention programs should include exercises that facilitate transferring and generalizing learned material in various anxiety-provoking situations.

Published: December 2024

E-learning systems are transforming the educational sector and making education more affordable and accessible. Recently, many e-learning systems have been equipped with advanced technologies that facilitate the roles of educators and increase the efficiency of teaching and learning. One such technology is Automatic Essay Grading (AEG) or Automatic Text Scoring (ATS) systems. To enable educators to remain more focused on teaching, there is a dire need to develop a more efficient use of their time. This is where automatic systems come into play, but they are still encountering an ongoing challenge due to many complex aspects, such as covering students’ creativity, novelty, context, subjectivity, coherence, cohesion, and homogeneity. The proposed study chose the Kaggle dataset of the Hewlett Foundation competition to cover this gap. It contains eight different essay sets based on student-written essays and their different range-based scores. Firstly, a score quantification method is applied to domain scores. Moreover, the proposed study covered four different aspects of student-written essays and extracted cohesion features via sentence connectivity, coherence via sentence relatedness, statistical lexical features via the Term Frequency (TF)-Inverse Document Frequency (IDF) method, and discourse macrostructural features via calculating the unique pattern of each essay. Three different experiments based upon the combination of these features are conducted, the most effective combination of features remains as statistical lexical features and discourse macrostructural features whereas the Linear Regression method is used for score prediction. The average Quadratic Weighted Kappa (QWK) score of 0.9339 was achieved and outperformed previous solutions in terms of time, computation, and performance.
Teaching Historical Approaches to Public Health Educators: Lessons Learned from an Interprofessional Workshop
Authors: Harris Jim , Boster Dea , Green-Rennis Lesley , Lee Toni-Ann , Vos Sarah C. , Worthen Miranda , Jones Marian Moser
Published: December 2024

This article describes a National Endowment for the Humanities-funded Institute “Disease, Pandemics, and Public Health in the United States” held in the summer of 2023 on the campus of The Ohio State University. It discusses how the institute was developed, its content, and its pedagogical impact. This institute offered training in how to integrate a historical perspective into public health pedagogy for 30 instructors of varied rank from a range of academic institutions. More importantly, the institute established a long-lasting pedagogical community that continues to foster innovation in public health pedagogy long after the completion of the formal program. While the institute focused on pandemics in response to the COVID-19 pandemic, in this article we argue that this institute provides a powerful roadmap for meaningful interdisciplinary training that enables public health educators to effectively integrate historical methods, perspectives, and knowledge into their pedagogy in response to growing calls for greater historicization of contemporary threats to public health.
Radiomics and radiogenomics: extracting more information from medical images for the diagnosis and prognostic prediction of ovarian cancer
Authors: Zeng Song , Wang Xin-Lu , Yang Hua
Published: December 2024

Ovarian cancer (OC) remains one of the most lethal gynecological malignancies globally. Despite the implementation of various medical imaging approaches for OC screening, achieving accurate differential diagnosis of ovarian tumors continues to pose significant challenges due to variability in image performance, resulting in a lack of objectivity that relies heavily on the expertise of medical professionals. This challenge can be addressed through the emergence and advancement of radiomics, which enables high-throughput extraction of valuable information from conventional medical images. Furthermore, radiomics can integrate with genomics, a novel approach termed radiogenomics, which allows for a more comprehensive, precise, and personalized assessment of tumor biological features. In this review, we present an extensive overview of the application of radiomics and radiogenomics in diagnosing and predicting ovarian tumors. The findings indicate that artificial intelligence methods based on imaging can accurately differentiate between benign and malignant ovarian tumors, as well as classify their subtypes. Moreover, these methods are effective in forecasting survival rates, treatment outcomes, metastasis risk, and recurrence for patients with OC. It is anticipated that these advancements will function as decision-support tools for managing OC while contributing to the advancement of precision medicine.
Gonadotropin Therapy for Mini-Puberty Induction in Male Infants With Hypogonadotropic Hypogonadism
Authors: Rhys-Evans Sophie , d’Aniello Francesco , Alexander Emma C , Dinah Ibrahim F , Heger Sabine , Nordenstrom Anna , Rohayem Julia , Howard Sasha R
Published: December 2024

Context

Congenital hypogonadotropic hypogonadism (CHH) is defined as an isolated deficiency of gonadotropin hormones. Mini-puberty, a transient postnatal activation of the hypothalamic-pituitary-gonadal axis in healthy infants, provides a window of opportunity to diagnose and treat CHH. Currently, in male infants with CHH, testosterone is used to increase phallus size. However, gonadotropin replacement could additionally promote testicular descent and development, particularly relating to Sertoli cells. We conducted a systematic review of the effectiveness of gonadotropin therapy in stimulating mini-puberty related outcomes in male infants with CHH.

Evidence Acquisition

In line with PRISMA guidelines, a systematic review of 11 databases was carried out (August 2023). Evidence quality was assessed using the Cochrane Risk of Bias for Non-Randomised Studies of Interventions tool. Protocol registered on PROSPERO (CRD42023453080).

Evidence Synthesis

After a double-consensus screen of 767 abstracts and 66 full texts, 11 studies were included from 7 countries. A total of 71 male infants were enrolled, 12 with Kallmann syndrome. Median age at treatment initiation was 4.2 months (range, 0.25-57 months) and follow-up ranged from 3 to 10 years. Gonadotropin therapy was administered using continuous subcutaneous infusion (n = 35) or subcutaneous injection (n = 36). Due to treatment variability, modalities were combined for data synthesis. Gonadotropins induced a statistically significant increase in penile length and inhibin B concentration (P = .0007) and led to partial or full testicular descent in 73% (n = 62) of patients.

Conclusion

This systematic review provides unique evidence supporting the efficacy of gonadotropins for induction of mini-puberty. However, the reliability and generalizability are limited due to disparate data and treatment modality variation.
Prevail of safety requirements for explosive industrial technologies in practice
Authors: Zsarnovszki Attila , Elek Barbara
Published: December 2024

Industrial production processes often result in potentially explosive areas. While the safety requirements for explosion protection are laid down in binding directives for the Member States of the European Union and the means to achieve these objectives are developed by the national authorities of the Member States, the requirements for the safety of explosive technologies are constantly changing. In recent years, this change has brought with it new risks of a new nature, the nature of which is not yet known. The aim of our research are to investigate how explosion protection safety aspects are prevailed in practice and to identify the causes of the non-compliances found. Our qualitative research was carried out as a retrospective case study. Among our results, we managed to identify patterns in the occurrence of non-compliances, revealing that the reasons for the existence of non-compliances are mainly rooted in human and organisational factors.
The emergence of elements of psychological safety in education during the completion of team tasks
Authors: Mészáros Ádám , Csiszárik-Kocsir Ágnes
Published: December 2024

The concept of security can take many forms, from physical security to mental and emotional security. Today's rewritten economic system and the way organisations operate require new competences and skills that we have rarely seen before. Such new requirements include an agile approach, project orientation, but also teamwork, which has taken on a role never seen before. Agile methodologies also emphasise teamwork and responsibility, which is an integral part of a safe environment. Students also need a sense of security to perform well, which is also true for working in a team. In education, psychological safety can be affected by a number of factors. The aim of our study is to investigate the psychological safety factors that appear during a team task based on the results of a primary quantitative research.

Study of chemical accident in light of hazard zone creating
Authors: Nagy Rudolf
Published: December 2024

The use of chemicals is found in all aspects of life. Chemical safety, as an interdisciplinary element of environmental safety, is particularly important in ensuring the safety of activities involving chemicals.

However, the risks posed by the application and use of chemicals are not the same in all spheres of application. One need only think of hazardous plants, where the increase in the associated technological scale and volumes leads to changes in safety levels. Moreover, other dangerous technical parameters associated with the operation of the plant, such as overpressure, high temperatures, etc., also have a significant influence on safety. These non-conformities can be the cause of accidents on a local or even regional scale, which can lead to damage areas of varying scale, not only geographically but also in terms of risk. The effects of the factors behind these possible differences are important criteria for the way in which the assessment of the situation and the response to chemical accidents should be carried out.

Point-of-Care Ultrasound Bootcamp Training: A Pilot Program for Internal Medicine Residency
Authors:   University of Arizona College of Medicine – Phoenix, Phoenix, AZ USA, Ma Mariel , Abbas Firas , Puebla Neira Daniel , Merz Jordan , Migotto Walter , Mathew Manoj
Published: December 2024

Background: The goal of the study was to develop a pilot program to assess point-of-care ultrasound (POCUS) knowledge and proficiency via a bootcamp-style education. The primary endpoints were to objectively identify trainees’ ability and interest to learn POCUS.
Methods: A POCUS education program was designed for 41 post-graduate-year-1 trainees’ orientation in an internal medicine residency program. Trainees were provided brief lectures on lower extremity veins, lung, and abdominal pathologies before proceeding to stations to practice ultrasound skills. An anonymous test was completed by each participant before and after they were provided lectures and practice time. The percent correct for each question before and after the intervention was compared using a paired t-test. The study was determined to be exempt by the University of Arizona IRB review.
Results: Primary outcomes found that 100% of the trainees improved on their knowledge of ultrasound based on a post-didactic assessment, and all questions except for one was statistically significant. The average pretest correct was 46% and posttest correct 84% (p<.001). Feedback on the sessions was assessed using Word Cloud. A higher number of trainees reported interest in applying POCUS to clinical practice after the session. The bootcamp was helpful when using videos, case examples, and small groups. Areas of improvement included providing more practice time, feedback on images obtained, and teaching cardiac ultrasound.
Conclusion: Internal medicine trainees were able to effectively learn the basics of POCUS, and they were more likely to use ultrasound after gaining knowledge.
‘Run three laps around the house’: a bricolage of rural ideals and co-parenting practices
Authors: Lundberg Janna , Ennerberg Elin
Published: December 2024

This article connects rural sociology and personal life theory by considering how conceptions of love, childhood and family life are understood in Swedish rural contexts. Complex personal rural life narratives are presented from the perspective of the ‘ordinary’. Our result accounts for how imagined families and rural life arrangements are negotiated and how families that are happy with their personal lives conceptualise their choices in relation to their rural homes. Finding a partner and establishing a happy family impacts the choice of where to live and how to work. We argue that the informants’ attempts to negotiate their imagined family ideals and rural lives involve attempting to counterbalance contemporary ideas of gender equality within their rural everyday life practices. When they are unable to fulfil their imagined families successfully, they experience a ‘debt of love’ within their family.
On the Edge: The Theater of Refusal (Black Art and Mainstream Criticism)
Authors: Tani Ellen
Published: December 2024

ABSTRACT: This article examines the 1993 exhibition The Theater of Refusal: Black Art and Mainstream Criticism , conceived by conceptual artist Charles Gaines. Displaying artworks by eleven Black artists alongside criticism about their work, the exhibition aimed to reveal the limitations of the discourse of marginality and the structures of stereotype employed by mainstream criticism. In reading Theater of Refusal in the context of his systems-driven artwork and his theoretical attunement, I position Gaines as a key interlocutor in a heated moment of cultural tension often subsumed by the notoriety of the 1993 Whitney Biennial, whose antagonistic reception by the art world was an outcome of the very systems—public discourse, the art world, sites of display, language—that the exhibition represented.
Journal to Find a Voice in Writing: Practitioner Commentary
Authors: Klein Mary Ellen
Published: December 2024

Abstract: This practitioner commentary is in response to regular journal writing experiences for high school students to encourage the development of voice in student-produced writing. The goal was to provide interesting prompts and flexibility in expression at regular intervals with an opportunity to revise a singular entry to develop an authentic writing style. Student participation varied so greatly that the assessment of stylistic growth in students' voice in writing was not easily discernible. Student engagement, attitude, and confidence played significant roles in their growth in addition to the written practice, revision, and products. Overall the practice is valuable and can be suited for any classroom environment with the right tools, effort, and approach.
Between the Archive and the Artworld: Writing Gendered Histories of Ibero-American Photography
Authors: Otayek Michel
Published: December 2024

Abstract: In recent years, a growing body of scholarship on women photographers in mid-twentieth-century Ibero-America has emerged in connection with exhibitions that have helped bring their work to the larger public. However, the importance given to notions of individual authorship, originality, and rarity in art market dynamics, institutional practices, and critical discourse on photographic images encourages scholarly work that often overlooks their print culture context. In this essay I argue that careful attention to the role of illustrated magazines as media for the circulation of photographic images helps us recognize photography’s value as an emancipatory practice that empowered women in rapidly expanding markets of print culture. To illustrate this proposition, I examine images by Kati Horna and Grete Stern, whose trajectories as exiled photographers working in proximity to the illustrated press exemplify the role played by women of Central European origin in shaping the medium’s gendered history in Ibero-America.
Making a Journalist’s Portrait: Flor Romero in Mid-Twentieth-Century Colombia
Authors: Sánchez-López Sandra
Published: December 2024

Abstract: This article explores key aspects of the history of Flor Romero, a leading figure of the women’s press in 1960s Colombia. Romero engaged in a quest to provide quality journalism to women readers and opportunities for women journalists, in which the writing itself constituted a means to further women and secure their visibility in the public forum. But while she fought against women’s exclusion in the press, Romero also adopted the language of her time and published stories that extolled being middle class. With this, she turned her gender crusade into a class narrative at a time when middle-class identity became crucial for and in circulating discourses of democracy. Not only is the study of Romero important to completing a chapter of Colombian and, for that matter, Latin American print culture and women’s history, it is also vital to illustrate the means historians have at hand to keep producing a history of journalism in its own right, based on a variety of source material.
A Family Affair? Women’s Amateur Cinema in 1930s–1950s Catalonia
Authors: Navarro Alejandra Rosenberg
Published: December 2024

Abstract: A handful of women stand out as amateur filmmakers in Catalonia’s rich twentieth-century amateur scene (such as Madronita Andreu); others appear in the shadow of their husbands’ work. This article focuses on the trajectories of female Catalan amateur filmmakers Francesca Trian, Emilia Martínez, and Miquelina Fiter, who worked with and for their husbands; the archival traces of their careers often appear under their partners’ names. This article asks: How do we undertake a feminist archival film history through social, institutional, and historical structures that obscure women’s labor? How do we determine authorship in amateur and domestic cinema? Using cinematographic and print culture archival research, this article presents the case of three women amateur filmmakers active before the Spanish Transition whose work is only accessible through state archives and ephemera that document their filmmaking trajectory.
Radio, Exile, and Feminisms: Spanish Republican Women Writers in Buenos Aires
Authors: López Lorena Paz , Rankin Tess
Published: December 2024

Abstract: In this article I explore how radio served as an important platform in the intellectual and feminist trajectories of Spanish Republican women writers living in exile in Argentina after its vast expansion as a form of mass media in the 1930s. Radio took off around the country at a particular moment for feminisms, when women were asserting their social and political rights and becoming more active in the public sphere. This moment coincided with the arrival of intellectuals exiled following the Spanish Civil War (1936–1939) and their incorporation into the cultural market. Through a study of writers María Teresa León’s (1903–1988) and María Martínez Sierra’s (1874–1974) participation in cultural activities on Radio El Mundo in 1942–1943 and Radio Nacional in 1959, respectively, I examine their relationship with the medium and how contact with this new communication technology led them to transform the kinds of cultural products they created in order to develop their feminist ideas through radio broadcasts. I argue that although this radio archive has received scant critical attention, recuperating and analyzing it allows us to complicate our view of the relationship that exiled women had with their host culture and to have a broader understanding of the Republican exile.
Gender, Colonialism, and the Archive: A Spanish Female Doctor among a Fang Community in 1940s Río Muni
Authors: Vizcaya Benita Sampedro
Published: December 2024

Abstract: Medical interventions played a pivotal role in the colonization of Africa, including in the Spanish Territories of the Gulf of Guinea, where they served as instruments for colonial expansion, control, repression, and institutionalized racism. Erasures in the dynamics of medical and scientific practices—including gendered erasures—are commonplace in colonial archiving. The Spanish female doctor Avemaría Vila Coro served nine years as a pediatrician and maternal health care doctor at the Catholic mission of Nkue-Fulán, in the Río Muni region, among Fang communities. She was responsible for the mission’s dispensary, hospital, and orphanage from 1944 to 1953. From outside the state-run colonial health system, she resisted mainstream medical approaches to colonial health; and as the author of numerous scientific essays on prenatal, maternal, and childcare medicine, she engaged with Fang pharmacology and medical knowledge. Activating a gender perspective on colonial health experiences and interpretations, this article attempts to resituate the participatory role of Spanish women in colonial health sciences in Africa. It is also intended as an archival supplement to the dominant male narrative of colonial science. It finally strives to stimulate a reflection on what lies at the intersection of gender, medical sciences, colonialism, and the archive.
Head Shaving: Archives and Repertoires of Shame
Authors: Rosón María , Pol Ana
Published: December 2024

Abstract: In this article we address the intersection of the archive and sexual violence by examining the Francoist practice of shaving the heads of Republican women during the Spanish Civil War (1936–1939) and at the start of the dictatorship. We question the limits of the archive to record actions or embodied narratives that leave few material traces, and about the conditions under which memories that are saturated by violence and trauma can be excavated. We analyze two of the few extant photographs: in them we see how the processes of performativity that accompany acts of violence unfold and expand over time. The photographs reify or represent shame and silence, but they also make remembering possible. The ways in which the photographs have circulated heighten the unstable, fragile nature of these haunted archives.

Art and Beauty as Being-for-Itself: Robert Spaemann's Aesthetics
Authors: Ramelow Anselm
Published: December 2024

Abstract: Robert Spaemann's aesthetics has yet to receive a comprehensive treatment, and this article is the first attempt to do so. Spaemann's way of resurrecting the Aristotelian notion of art as imitating nature is unusual, including for Aristotelians. The nature that is visibly imitated is, ultimately, invisible, and spiritual. This quasi-sacramental understanding leads Spaemann to appreciate contemporary art as well. Art's imitation of the invisible is a call to self-transcendence and a reminder of our own spiritual nature.
The Theory of Ideas in Schelling's Identity System: A Wittgensteinian Interpretation
Authors: Yaretzky Amir
Published: December 2024

Abstract: This article offers an interpretation of Schelling's theory of ideas within his philosophy of identity, arguing that it should be understood as a theory of the intelligibility of being—that is, the capacity for the world to be meaningfully articulated in thought. By placing Schelling's ideas into dialogue with Wittgenstein's Tractatus Logico -Philosophicus, the author aims to show how Schelling's philosophy might provide valuable insights for contemporary analytic interpretations of German idealism. Schelling's notion of ideas encompasses three key features: (1) they express the principle of identity as the foundation of reality, (2) they constitute totalities or self-contained universes, and (3) they are individuals that are unified within a single totality. The author explains these features and demonstrates how they jointly establish the conditions necessary for the possibility of meaning and coherent thought.
CubEd: a 3D printable fluorescence cube microscope optimized for classroom and teaching use

Published: December 2024

“When all you have is a hammer, everything is a nail” diametrically opposes the “right tool for the job” mentality. After observing graduate students in the biological sciences often adopting the former approach towards fluorescence light microscopy – using religiously the closest available microscope rather than the most suitable on campus – we endeavored to shift mentality towards the latter through teaching how the tools work. We further observed that these students often lack an understanding of optics. To instill a practical knowledge of optics as applied in fluorescence microscopy, we set about to create an educational experience that linked theory and practice. As part of this effort, we provided students an opportunity to construct fluorescence microscopes in an open-ended, stepwise fashion with built-in features, such as the ability to track the beam along the beam path. As a result, we developed the CubEd, an easy-to-use, inexpensive, and extensible optics system that may lead students to a better understanding of how fluorescence microscopy works, and, as a result, will enable them to better design their own experiments in the future. This requires replacing expensive, closed system, boxed commercial microscopes with a modular, open frame system that allows direct access to the optics. Based on an early iteration of the UC2 microscope, the CubEd was conceived. It is an open-source microscope of modular design that balances cost, ease-of-use, flexibility of design, and extensibility.
Quantum Key Distribution based Physical Layer Security applied in complex modulation formats for Optical Fiber links
Authors: Nikas Thomas , Rousas Eleftherios , Pekridis Georgios , Karabetsos Sotiris , Syvridis Dimitris
Published: December 2024

A Quantum Key Distribution (QKD) based Physical Layer Security (PLS) scheme (QKD-PLS) for optical fiber links is proposed and evaluated. In detail, a novel amplitude and phase scrambling technique for exploiting and seamlessly integrating high key rate QKD for the encryption of the modulation parameters of conventional complex modulation schemes like M-ary Quadrature Amplitude Modulation (M-QAM) and Orthogonal Frequency Division Multiplexing (OFDM) is described. The technique masks the information at the bit level and blocks unauthorized access to the higher layer encrypted bitstream. Scrambling is applied to both the preamble (pilot) and payload segments of the transmission frame, to prevent the eavesdroppers from performing vital receiver functions such as frame synchronization and channel estimation. Additionally, a practical Key Management System (KMS) which takes care of all synchronization processes is developed and introduced. Experimental transmission scenario in fiber links is also presented and depicts the efficacy of the QKD-PLS. Moreover, another advantage of QKD exploitation to the proposed solution comes from the application of kbps-rate QKD keys which feed pseudo-random number generators, to modify the broadband modulation symbols in one-time pad, therefore significantly improving data protection.
Diagnostic results of new-generation dispersive element test samples based on Bragg structures in fused silica
Authors: Gorokhov Anton , Perevezentsev Evgeny , Volkov Mikhail , Mukhin Ivan
Published: December 2024

A comprehensive diagnostics of new-generation dispersive elements based on Bragg structures was completed. The influence of inscription parameters on the properties of samples was studied and a threshold inscription intensity of ~ 6.38 TW/cm2 at which the linear absorption coefficient as well as the phase and polarization stresses sharply increase was found. When inscription is made with an average intensity below the threshold, the linear absorption in dry silica samples remains at a level of 10-5 cm-1, which is approximately two orders of magnitude lower than that of currently available commercial samples. The measured values of the dispersion characteristics using a white light interferometer coincided are in a good agreement with the calculated values provided by the manufacturer. The results of the diagnostics show that the new-generation dispersive elements are promising for compressing kilowatt-level radiation of average power.

Published: December 2024

Background and Aim: Anthocyanins are potent antioxidants and scavengers of free radicals found in fruits, purple corn, and other naturally occurring purple plants. Several studies have demonstrated that anthocyanins possess strong antioxidant properties and can enhance ruminant production by modulating intracellular oxidative stress and modifying ruminal fermentation. This study aimed to examine the effects of anthocyanin-rich Napier grass silage (ANS) on feed intake, nutrient digestibility, milk production, plasma profile, and antioxidant capacity in lactating crossbred Saanen goats.

Materials and Methods: Nine healthy lactating goats (crossbreeds of Thai-native and Saanen breeds aged 8–12 months) were selected and randomly assigned to one of three experimental diets: (1) Corn silage (CS), (2) Napier grass silage (NS), and (3) ANS. Daily feed refusals were recorded to calculate dry matter intake for the animal performance assessment. In addition to analyzing feed intake, nutrient intake, and nutrient digestibility, milk and blood samples were also analyzed for protein composition, leukocyte count, and antioxidant capacity.

Results: CS-fed goats had the highest (p < 0.05) feed intake (1.09 kg/day), a value markedly exceeding those of NS- and ANS-fed goats (0.80 and 0.76 kg/day, respectively). They also had higher (p < 0.05) organic matter (OM) and neutral detergent fiber intake (0.99 kg and 0.50 kg/day) than the other two groups. Protein intake did not differ significantly (0.14, 0.12, and 0.12 kg/day for CS, NS, and ANS, respectively). The CS group showed higher (p < 0.05) dry matter and OM digestibility (69.42% and 69.83%) than the NS and ANS groups, which had lower (p < 0.05) fiber digestibility. Regarding milk production, the CS and ANS groups produced 1.15 and 1.16 kg/day, respectively, whereas the NS group produced 1.11 kg/day. No significant differences in leukocyte counts were observed. Furthermore, the CS group exhibited the highest (p < 0.05) superoxide dismutase inhibition (16.05%) on day 35, whereas the ANS group showed the highest (p < 0.05) total antioxidant capacity on multiple days (21, 35, 49, and 63).

Conclusion: ANS can be a valuable component of dairy goat diets, particularly in regions prone to heat-induced oxidative stress.

Napjainkban a kultúrához való hozzáférés az életminőség fontos része. A rendszeres kultúrafogyasztás eredményeként a helyek a lakosok és az ideiglenes látogatók számára egyaránt vonzóbbá válnak. Ennek megfelelően a helyi döntéshozatal kiemelt figyelmet szentel annak, hogy a városok, térségek imázsát és versenyképességét javító kulturális szolgáltatásokat mindenki számára elérhetővé tegye. A Veszprém-Balaton 2023 Európa Kulturális Fővárosa programsorozat keretében megvalósult Pajta Program célkitűzése a kulturális programok elérhetővé tétele és a közösségépítés volt. Jelen tanulmány a Pajta Programban részt vevőkkel készült interjúk eredményeire építve tárja fel a program hatásait. A kutatás eredményei szerint a program pozitívan befolyásolta a térséget, a már meglévő folyamatok erősítése mellett új távlatokat, lehetőségeket nyitott a helyi közösségi élet számára. Jelen tanulmány javaslataival kapcsolatban kiemelendő, hogy a döntéshozók számára visszacsatolást ad az ilyen jellegű programokról, azok potenciális hatásairól. A helyi közösségek – ideértve a lakosságot és a szolgáltatókat – számára a kutatás feltárta a bekapcsolódási lehetőségeket.

A Budapesti Corvinus Egyetem Vezetéstudományi Intézete saját kutatási projekt keretében indított nagymintás kutatást a magyarországi vállalatvezetők körében. A kutatás célja az volt, hogy minél komplexebb kép legyen a Magyarországon működő szervezetek és vezetők működési gyakorlatáról, a jövő szervezetére és vezetőjére vonatkozó elképzelésekről. A 300 feletti minta összeállítása jól tükrözi a hazai vállalati szektor összetételét. A kutatói csapat komplex módon közelítve igyekezett feltárni a külső környezeti hatásokat, a belső szervezeti jellemzőket, a stratégiai gondolkodás tartalmát, a nemzetközi növekedési terveket, a gátlótényezőket, amelyek meghatározhatják a jövő vállalatának sikerét. Jelen tanulmány célja, a hazai vállalatok versenyképességének elemzése, fókuszálva a nemzetköziesedés aspektusára. A jövő versenyképessége a vállalat reziliens működésének alapja, a mai változó környezetben ennek megértése kritikusan fontos tényező.

Published: December 2024

The exploration and development of groundwater in the Precambrian Basement Complex of Ayegunle / Oka Akoko was necessitated because of perennial scarcity of potable water for communal purposes. The study was aimed at delineating the prolific aquiferous zones by the use of electromagnetic and Schlumberger- Vertical Electrical Sounding (VES) methods. Twenty (20) electromagnetic (EM) and electrical resistivity traverses of 100m long were carried out using Geonics co-planar loop system and ABEM SAS1000 Terameter. The EM and VES data were plotted against station position inverted and analyzed in terms of the conductivity and geo-electric parameter (apparent resistivity, depth and thickness) distribution in the area. The EM and VES dataset was processed using Karous-Hjelt and WinResist softwares. The interpretation of the electromagnetic profiles revealed some conductive zones that were prioritized for depth sounding. The result showed crossover point that diagnostic of conductivity. The apparent resistivity, depth and thickness of the subsurface strata ranges from: 81-1299 Ωm, 0.5-105.1m and 0.5-76.9m respectively. The lithologic strata vary from topsoil, clay/sandy clay, weathered/partially weathered, fractured/basement bedrock. The hydro-geologic cross-sections were categorized into: high, midrange, and low groundwater potential. The geophysical survey data revealed that the study region has the potential to play a key role in delivering adequate drinkable water for rural residents.

Published: December 2024

This study investigates how stochastic optimization is applied to the management of a company's portfolio in order to maximize the expected utility of wealth over a given period. Inspired by Merton's research, this model involves random volatility in the financial markets, while maintaining a constant interest rate to take better account of real economic uncertainties. The aim is to formulate optimal investment and consumption strategies based on Pontryagin's maximum principle. Taking into account key factors such as economic growth and market volatility, as well as risk aversion in our financial considerations, we recommend an approach incorporating a quadratic penalty for excessive investment. This innovative method aims to adjust financial choices in line with economic fluctuations and ensure prudent management of the company's monetary resources. Finally, numerical simulations illustrate the influence of these factors on overall wealth, as well as on investment and consumption, underlining the importance of prudent portfolio management during periods of uncertainty.
