Authors: Llorca-Tonda María Ángeles
Published: September 2024

Los abundantes estudios sobre Christine de Pizan han tendido a centrarse más en una parte de su obra —escritos filosóficos, didácticos y políticos— en detrimento de otra. Es el caso de los escritos religiosos de esta escritora medieval que hasta hace poco solo habían despertado el interés de unos pocos especialistas. Las ediciones recientes de estas obras han posibilitado su visibilidad. Los objetivos de este trabajo son los de ofrecer una somera presentación del legado literario religioso de Christine de Pizan y el de analizar más en detalle una de las obras en prosa que conforman dicho legado: Heures de contemplacion sur la Passion de Nostre Seigneur Jhesucrist. El estudio de este texto sobre la Pasión de Cristo nos permitirá poner de relieve someramente algunas de las peculiares que lo caracterizan y a situar a Christine de Pizan en la tradición medieval de la escritura religiosa.

La guerra sucia en México: prácticas de la memoria en la escena del siglo XXI
Authors: Aracil Varón Beatriz
Published: September 2024

México es un país que ha mantenido a lo largo del pasado siglo una imagen democrática y neutral en el panorama internacional y, sin embargo, ha ejercido una violencia represora contra las voces disidentes. Esta violencia fue especialmente cruenta durante los 60 y 70, años en los que surgieron grupos guerrilleros que transformaron su lucha social en una lucha armada y que fueron aplastados por fuerzas policiacas y militares con métodos claramente ilegales como detenciones masivas, torturas y desapariciones.
En el presente trabajo se contextualizan y examinan dos montajes escénicos casi coetáneos que han tematizado este convulso período de la "guerra sucia" mexicana: Moctezuma II, la guerra sucia (2009), de Juliana Faesler, y El rumor del incendio (2010), de Lagartijas Tiradas al Sol. El objetivo es observar cómo la preocupación por recordar lo que ocurrió por parte de los grupos teatrales que emergen o desarrollan la mayor parte de su producción en el siglo XXI viene determinada por la distancia generacional respecto a quienes protagonizaron o fueron testigos del período histórico abordado. Ello obliga a una construcción distinta de la memoria que obedece a su vez a los modos de reflexión sobre la identidad predominantes en el México de hoy.
Análisis del canon de belleza femenina y su manipulación digital en la publicidad de perfumes
Authors: Muñoz-Muñoz Ana M. , Martínez-Oña M. Mar
Published: September 2024

La belleza femenina es un fenómeno cultural de la sociedad, donde el canon de belleza reproducido en la publicidad convierte a las mujeres en un producto más del mercado de consumo. En la actualidad, la belleza femenina se rediseña por programas de retoque fotográfico o por filtros digitales de aplicaciones móviles que manipulan las imágenes femeninas, creando mujeres irreales. Este artículo pretende identificar como se consigue el modelo femenino de belleza difundido en la sociedad a través de la publicidad. Para ello, se aplicó un método iconográfico y comparativo a través del programa Adobe Photoshop, se seleccionaron 100 anuncios de perfumes, publicados entre los años 2000 y 2020, que se cotejaron con otras imágenes no publicadas, cuyas correcciones eran mínimas o inexistentes. A partir de una serie de variables se analizó el actual canon de belleza femenina y cómo se había aplicado este a las diferentes modelos femeninas. Los resultados obtenidos muestran que todas las imágenes se han manipulado para alterar la estética de las modelos, idealizando una belleza irreal femenina que establece un canon difícilmente alcanzable para las mujeres.

Perceived Vulnerability to Disability-Related Victimization in People With Multiple Sclerosis: Community Survey on Risk and Protective Factors
Authors: Munroe Leah A. , Rivera Donovan , Flaster Aaron , Molton Ivan
Published: September 2024

BACKGROUND:

The perception that one is at increased risk of interpersonal victimization or violence can deleteriously affect community participation and quality of life. Race, sex, and disability status, often associated with use of an assistive mobility device (AD), are known correlates of perceived risk of victimization; however, almost no research has explored how these variables intersect for individuals with multiple sclerosis (MS), and none have sought to identify potential risk and protective factors.

METHODS:

Data for the present study come from a single time point derived from a 10-year longitudinal survey of 446 individuals with MS. Lifetime trauma exposure, personal resilience and self-efficacy, control over participation, and perceived risk of interpersonal victimization due to disability were all assessed via self-report. Statistical analyses included analysis of covariance with participants stratified by race/ethnicity, sex, and AD use.

RESULTS:

After controlling for lifetime trauma exposure and severity of physical impairment, the use of an AD was significantly associated with greater perceived risk of victimization due to disability. Further, people with MS from racial and ethnic minority groups who used ADs had the highest perceived risk relative to all other groups. Higher levels of perceived risk were associated with a lower sense of control over community participation, lower resilience, and lower disease management self-efficacy.

CONCLUSIONS:

Visible indicators of disability may contribute to perceptions of vulnerability, especially among people with MS who are racially and ethnically marginalized. Clinicians should be aware of how perceived vulnerability may impact a sense of control over community participation, particularly when educating patients on AD use.

A comparative study of the cryo-EM structures of S. cerevisiae and human anaphase-promoting complex/cyclosome (APC/C)
Authors: Vazquez-Fernandez Ester , Yang Jing , Zhang Ziguo , Andreeva Antonina E , Emsley Paul , Barford David
Published: September 2024

The anaphase-promoting complex/cyclosome (APC/C) is a large multi-subunit E3 ubiquitin ligase that controls progression through the cell cycle by orchestrating the timely proteolysis of mitotic cyclins and other cell cycle regulatory proteins. Although structures of multiple human APC/C complexes have been extensively studied over the past decade, the
S. cerevisiae
APC/C has been less extensively investigated. Here, we describe medium resolution structures of three
S. cerevisiae
APC/C complexes: unphosphorylated apo-APC/C and the ternary APC/C
CDH1
-substrate complex, and phosphorylated apo-APC/C. Whereas the overall architectures of human and
S. cerevisiae
APC/C are conserved, as well as the mechanism of CDH1 inhibition by CDK-phosphorylation, specific variations exist, including striking differences in the mechanism of coactivator-mediated stimulation of E2 binding, and the activation of APC/C
CDC20
by phosphorylation. In contrast to human APC/C in which coactivator induces a conformational change of the catalytic module APC2:APC11 to allow E2 binding, in
S. cerevisiae
apo-APC/C the catalytic module is already positioned to bind E2. Furthermore, we find no evidence of a phospho-regulatable auto-inhibitory segment of APC1, that in the unphosphorylated human APC/C, sterically blocks the CDC20
C-box
binding site of APC8. Thus, although the functions of APC/C are conserved from
S. cerevisiae
to humans, molecular details relating to their regulatory mechanisms differ.
Connecting Chromatin Structures to Gene Regulation Using Dynamic Polymer Simulations

Published: September 2024

The transfer of regulatory information between distal loci on chromatin is thought to involve physical proximity, but key biophysical features of these contacts remain unclear. For instance, it is unknown how close and for how long two loci need to be in order to productively interact. The main challenge is that it is currently impossible to measure chromatin dynamics with high spatiotemporal resolution at scale. Polymer simulations provide an accessible and rigorous way to test biophysical models of chromatin regulation, yet there is a lack of simple and general methods for extracting the values of model parameters. Here we adapt the Nelder-Mead simplex optimization algorithm to select the best polymer model matching a given Hi-C dataset, using the
MYC
locus as an example. The model’s biophysical parameters predict a compartmental rearrangement of the
MYC
locus in leukemia, which we validate with single-cell measurements. Leveraging trajectories predicted by the model, we find that loci with similar Hi-C contact frequencies can exhibit widely different contact dynamics. Interestingly, the frequency of productive interactions between loci exhibits a non-linear relationship with their Hi-C contact frequency when we enforce a specific capture radius and contact duration. These observations are consistent with recent experimental observations and suggest that the dynamic ensemble of chromatin configurations, rather than average contact matrices, is required to fully predict productive long-range chromatin interactions.

Published: September 2024

Globally, glaucoma is a leading cause of visual impairment and vision loss, emphasizing the critical need for early diagnosis and intervention. This research explores the application of deep learning for automated glaucoma diagnosis using retinal fundus photographs. We introduce a novel cross-sectional optic nerve head (ONH) feature derived from optical coherence tomography (OCT) images to enhance existing diagnostic procedures. Our approach leverages deep learning to automatically detect key optic disc characteristics, eliminating the need for manual feature engineering. The deep learning classifier then categorizes images as normal or abnormal, streamlining the diagnostic process. Deep learning techniques have proven effective in classifying and segmenting retinal fundus images, enabling the analysis of a growing number of images. This study introduces a novel mixed loss function that combines the strengths of focal loss and correntropy loss to handle complex biomedical data with class imbalance and outliers, particularly in OCT images. We further refine a multi-task deep learning model that capitalizes on similarities across major eye-fundus activities and metrics for glaucoma detection. The model is rigorously evaluated on a real-world ophthalmic dataset, achieving impressive accuracy, specificity, and sensitivity of 100%, 99.8%, and 99.2%, respectively, surpassing state-of-the-art methods. These promising results underscore the potential of our deep learning algorithm for automated glaucoma diagnosis, with significant implications for clinical applications. By simultaneously addressing segmentation and classification challenges, our approach demonstrates its effectiveness in accurately identifying ocular diseases, paving the way for improved glaucoma diagnosis and early intervention.
Semiautomated generation of species-specific training data from large, unlabeled acoustic datasets for deep supervised birdsong isolation
Authors: Sasek Justin , Allison Brendan , Contina Andrea , Knobles David , Wilson Preston , Keitt Timothy
Published: September 2024

Background

Bioacoustic monitoring is an effective and minimally invasive method to study wildlife ecology. However, even the state-of-the-art techniques for analyzing birdsongs decrease in accuracy in the presence of extraneous signals such as anthropogenic noise and vocalizations of non-target species. Deep supervised source separation (DSSS) algorithms have been shown to effectively separate mixtures of animal vocalizations. However, in practice, recording sites also have site-specific variations and unique background audio that need to be removed, warranting the need for site-specific data.

Methods

Here, we test the potential of training DSSS models on site-specific bird vocalizations and background audio. We used a semiautomated workflow using deep supervised classification and statistical cleaning to label and generate a site-specific source separation dataset by mixing birdsongs and background audio segments. Then, we trained a deep supervised source separation (DSSS) model with this generated dataset. Because most data is passively-recorded and consequently noisy, the true isolated birdsongs are unavailable which makes evaluation challenging. Therefore, in addition to using traditional source separation (SS) metrics, we also show the effectiveness of our site-specific approach using metrics commonly used in ornithological analyses such as automated feature labeling and species-specific trilateration accuracy.

Results

Our approach of training on site-specific data boosts the source-to-distortion, source-to-interference, and source-to-artifact ratios (SDR, SIR, and SAR) by 9.33 dB, 24.07 dB, and 3.60 dB respectively. We also find our approach allows for automated feature labeling with single-digit mean absolute percent error and birdsong trilateration accuracy with a mean simulated trilateration error of 2.58 m.

Conclusion

Overall, we show that site-specific DSSS is a promising upstream solution for wildlife audio analysis tools that break down in the presence of background noise. By training on site-specific data, our method is robust to unique, site-specific interference that caused previous methods to fail.
The test-retest reliability of a Body Posture Literacy Questionnaire among Polish teachers from different educational levels
Authors: Labecka Marta Kinga , Jankowicz-Szymańska Agnieszka , Plandowska Magdalena , Olszewska Elżbieta , Rajabi Reza
Published: September 2024

Background

The study aimed to develop a reliable and valid Teachers’ Body Posture Literacy Questionnaire (TBPLQ) to examine their body posture knowledge.

Methods

The tool was based on a Parents Body Posture Literacy Questionnaire (PBPLQ) and modified and validated through discussion with experts, conducted in two rounds. Corrective gymnastics, physiotherapy, ergonomics, and physical education (PE) experts and doctoral and postdoctoral scholars evaluated content validity. Test-retest repeatability was tested using Cohen’s kappa coefficient. The study used a convenience sample of 195 teachers from three different educational levels: PE, kindergarten, and primary education in two rounds of test-retest (pilot test-retest reliability and main test-retest reliability of the questionnaire). The first round encompassed 95 participants, with pre-test and post-test procedures applied using the original TBPLQ. The second round involved 100 participants and followed a similar approach, incorporating modifications to the TBPLQ based on the reliability outcomes observed in the first round.

Results

The results of the first-round test-retest TBPLQ reliability, with 95 samples, resulted in an overall reliability of 0.77 (range 0.02 to 1). This indicated that the questionnaire still lacks sufficient reliability. Consequently, after the necessary amendments and modifications, the questionnaire’s reliability was tested for the second time with 100 samples. Notably, the overall reliability of 0.82 (ranging from 0.50 to 1) was established for the TBPLQ indicating that 87.5% of the questionnaire items achieved reliability scores within the substantial and almost perfect range and only 12.5% of the items attained moderate reliability scores.

Conclusions

The questionnaire is a new self-report measure for evaluating teachers’ literacy in postural health. It is applicable in both research and practical contexts, extending its use to larger and more diverse populations.
Transcriptomic and coexpression network analyses revealed the regulatory mechanism of Cydia pomonella infestation on the synthesis of phytohormones in walnut husks
Authors: Cao Xiaoyan , Ye Xiaoqin , Sattar Adil
Published: September 2024

The codling moth (Cydia pomonella) has a major effect on the quality and yield of walnut fruit. Plant defences respond to insect infestation by activating hormonal signalling and the flavonoid biosynthetic pathway. However, little is known about the role of walnut husk hormones and flavonoid biosynthesis in response to C. pomonella infestation. The phytohormone content assay revealed that the contents of salicylic acid (SA), abscisic acid (ABA), jasmonic acid (JA), jasmonic acid-isoleucine conjugate (JA-ILE), jasmonic acid-valine (JA-Val) and methyl jasmonate (MeJA) increased after feeding at different time points (0, 12, 24, 36, 48, and 72 h) of walnut husk. RNA-seq analysis of walnut husks following C. pomonella feeding revealed a temporal pattern in differentially expressed genes (DEGs), with the number increasing from 3,988 at 12 h to 5,929 at 72 h postfeeding compared with the control at 0 h postfeeding. Walnut husks exhibited significant upregulation of genes involved in various defence pathways, including flavonoid biosynthesis (PAL, CYP73A, 4CL, CHS, CHI, F3H, ANS, and LAR), SA (PAL), ABA (ZEP and ABA2), and JA (AOS, AOC, OPR, JAZ, and MYC2) pathways. Three gene coexpression networks that had a significant positive association with these hormonal changes were constructed based on the basis of weighted gene coexpression network analysis (WGCNA). We identified several hub transcription factors, including the turquoise module (AIL6, MYB4, PRE6, WRKY71, WRKY31, ERF003, and WRKY75), the green module (bHLH79, PCL1, APRR5, ABI5, and ILR3), and the magenta module (ERF27, bHLH35, bHLH18, TIFY5A, WRKY31, and MYB44). Taken together, these findings provide useful genetic resources for exploring the defence response mediated by phytohormones in walnut husks.
Control of inorganic and organic phosphorus molecules on microbial activity, and the stoichiometry of nutrient cycling in soils in an arid, agricultural ecosystem
Authors: Chavez-Ortiz Pamela , Larsen John , Olmedo-Alvarez Gabriela , García-Oliva Felipe
Published: September 2024

Background

The dynamics of carbon (C), nitrogen (N), and phosphorus (P) in soils determine their fertility and crop growth in agroecosystems. These dynamics depend on microbial metabolism, which in turn depends on nutrient availability. Farmers typically apply either mineral or organic fertilizers to increase the availability of nutrients in soils. Phosphorus, which usually limits plant growth, is one of the most applied nutrients. Our knowledge is limited regarding how different forms of P impact the ability of microbes in soils to produce the enzymes required to release nutrients, such as C, N and P from different substrates.

Methods

In this study, we used the arable layer of a calcareous soil obtained from an alfalfa cropland in Cuatro Cienegas, México, to perform an incubation experiment, where five different phosphate molecules were added as treatments substrates: three organic molecules (RNA, adenine monophosphate (AMP) and phytate) and two inorganic molecules (calcium phosphate and ammonium phosphate). Controls did not receive added phosphorus. We measured nutrient dynamics and soil microbial activity after 19 days of incubation.

Results

Different P molecules affected potential microbial C mineralization (CO2-C) and enzyme activities, specifically in the organic treatments. P remained immobilized in the microbial biomass (Pmic) regardless of the source of P, suggesting that soil microorganisms were limited by phosphorus. Higher mineralization rates in soil amended with organic P compounds depleted dissolved organic carbon and increased nitrification. The C:N:P stoichiometry of the microbial biomass implied a change in the microbial community which affected the carbon use efficiency (CUE), threshold elemental ratio (TER), and homeostasis.

Conclusion

Different organic and inorganic sources of P affect soil microbial community structure and metabolism. This modifies the dynamics of soil C, N and P. These results highlight the importance of considering the composition of organic matter and phosphate compounds used in agriculture since their impact on the microbial activity of the soil can also affect plant productivity.

Authors: Sangolkar Deepa , Borkar Shweta , Ambhore Nakul , Ambhore Ashish , Sinha Nayan
Published: September 2024

Nail-Patella Syndrome (NPS) is a rare autosomal dominant illness. Patients typically exhibit a tetrad of dysplastic finger or toenails, elbow dysplasia, hypoplastic or missing patellae, and iliac horns as their first musculoskeletal and dermatological symptoms. A higher occurrence of psychiatric disorders, such as depression and attention deficit hyperactivity disorder, has also been reported with NPS. This is a rare case of NPS, presenting with depression as the major symptom in an 18-year-old young girl who presented to the psychiatry Outpatient Department (OPD) with depressive symptoms like persistent low mood, loss of pleasure or anhedonia, loss of appetite, disturbed sleep, and thoughts of death. After 10 days of treatment with antidepressant drugs like Benzodiazepines, she was discharged and followed-up on an OPD basis. After a thorough evaluation, hypoplastic patella, swan-necked nails, radial head subluxation, and right eye glaucoma were also noted, and a final diagnosis of Nail-Patella Syndrome was made. A case of NPS can present in any department, such as in Medicine for nail dysplasia, in Orthopaedics for elbow or patella dysplasia, or in Dermatology for iliac horns. Here, the case was primarily presented to the Psychiatry department and later managed by a team of physicians, orthopaedicians, and psychiatrists. Careful illustration of the family history reveals more cases.

Published: September 2024

Introduction: The key objective of Total Hip Replacement (THR) is to deliver a hip joint that is pain-free, mobile, and stable. For this procedure, both cemented and uncemented methods are offered. Aim: To compare the mid-term functional outcomes of uncemented Total Hip Arthroplasty (THA) versus cemented THA. Materials and Methods: A hospital-based retrospective cohort study was conducted on 60 cases of THA (both cemented and uncemented) operated at a tertiary-level medical institute in north India between January 2012 to December 2018. In this retrospective cohort study, sixty (60) hip replacements (both cemented and uncemented) were performed on patients between the ages of 25 to 70 at a tertiary care institute in rural north India between 2012 and 2018. Patients over the age of 25 who were diagnosed with pure hip arthritis due to conditions such as avascular necrosis, osteoarthritis, or hip developmental dysplasia and who were eligible for either an uncemented or a cemented THA were taken into consideration for inclusion. Retrospective patient monitoring was done based on Harris Hip Score (HHS) from January 2019 to August 2020. Results: In the cemented group, the mean age of the patients was 58.90±8.97, whereas in the uncemented group, it was 52.47±10.29. Out of 30 participants, 17 were male and 13 were female in the cemented group, and 19 male and 11 female participants were included in the study in the uncemented group. The difference between the cemented and uncemented groups’ HHS was significant during the immediate postoperative period (p=0.01). Nevertheless, there was no discernible difference at the long-term follow-up at one year (p=0.76), two years (p=0.20), three years (p=0.29), four years (p=0.86), and five years (p=0.47). Three years following surgery, radiographic evidence of osteolysis and loosening was observed in two instances (6.6%) in the uncemented group and two case (6.6%) in the cemented group. Conclusion: While cemented fixation offers better immediate functional results than uncemented fixation- such as less pain and faster pain-free full weight-bearing. Both have proven to be equally successful in the long run, with statistically insignificant differences.

Maxillonasal dysplasia, known as Binder’s syndrome, is a rare congenital deformity characterised by distinctive facial features, including a malformed midface and nose, as well as abnormal positions of the nasal bones. In addition, maxillary hypoplasia, or a shorter upper jaw, and nasal abnormalities may manifest as a flattened nose. Many cases of this condition are associated with other malocclusions, and those affected can be easily identified. Individuals with Binder’s syndrome typically present with an undeveloped upper jaw, a projecting lower jaw, a smaller nose, a flat nasal bridge, and midfacial hypoplasia. This is the first case report describing a physiotherapy method for maxillonasal dysplasia. Hereby, the authors present a case report of a six-month-old male child with Binder’s syndrome who exhibited delayed developmental milestones and physical anomalies. The child’s mother had a complicated pregnancy, culminating in an emergency caesarean section due to preterm premature rupture of membranes. The infant, born with Binder’s syndrome and a cleft palate, displayed poor head control, an inability to roll, and reluctance to engage in sensory interactions. Examination revealed bilateral cortical thumbs, hip joint abnormalities, and heightened sensitivity to touch. Magnetic Resonance Imaging (MRI) findings indicated semilobar Holoprosencephaly (HPE) and dysgenesis of the corpus callosum. Physiotherapeutic interventions focused on parent education and home exercise programs targeting developmental milestones. Over the course of two months, the infant showed significant progress in head control and rolling. Furthermore, after four months of training, the child gained sitting control. The present case underscores the importance of early intervention and parental involvement in optimising outcomes for children with Binder’s syndrome.
The Jehol Biota: a window into the Cretaceous world
Authors: Kosenko I.N.
Published: September 2024

The article provides an overview of information about the fossil Jehol biota, one of the most studied and well–preserved continental ecosystems of the Early Cretaceous. The Jehol biota is represented by an assemblage of fossils of excellent preservation, consisting of the remains of numerous plants, including the most ancient angiosperms, charophytes and dinocysts, freshwater gastropods and bivalves, numerous crustaceans (conchostracans, ostracods, higher crustaceans), insects, arachnids, fish, amphibians, turtles, choristodera, lizards, pterosaurs, dinosaurs, including feathered and birds, as well as the largest mammals of the Mesozoic, originating from the Lower Cretaceous Yixian and Jiufotang formations in northeastern China. However, similar deposits containing key elements of the Jehol biota – crustaceans Eosesteria, insects Ephemeropsis and fish Lycoptera are known from Transbaikalia. This may indicate that during large-scale excavations, the remains of vertebrate organisms, similar in preservation to the fossils of the Jehol biota, can also be found in Transbaikalia.

Broken Staff, Torn Clothes: Liutprand of Cremona on Papal Depositions
Authors: Anufrieva Anastasia
Published: September 2024

In the article are compared two descriptions of papal depositions, created by the Italian historiographer Liutprand of Cremona. One of these depositions the author sought to present as illegal, and the second, on the contrary, as completely legitimate. In the historical  work «Antapodosis» he described the so-called Cadaver Synod – posthumous deposition of Pope Formosus, for which the body of the pontiff was allegedly dug out of a grave. In the book «De Iohanne papa et Ottone imperatore» the historiographer wrote about the devestitura of Pope Benedict V, who was unwanted for Liutprand’s patron Otto I, the newly crowned Emperor of Romans. Using these two descriptions as an example, we show, which techniques did the medieval historiographer use to discredit the deposition of Formosus and to confirm legitimacy of the council of 964.
Development of the Common Law of England in the 12th – Beginning of the 13th Century and Pleas in a Cornish Justice in Eyre
Authors: Vinokurova Marina
Published: September 2024

The article is based on the research of the problem of formation and development of judicial legislation in the sphere of the early Common Law of England - with the involvement of materials, published by F.W. Maitland for Selden Society at the end of the 19th century, which represent claims to the visitorial Royal Court (or Justice in Eyre) in Cornwall in the third year of King John’s reign (1201); this might it possible to understand in what way grassroot claims from hundreds and manors spilled over into legal sphere of visitorial courts, which, as well as central ones, worked on the basis of «Coram Regis». A number of features of the gradual expansion of royal courts’ competence on the ground of Cornish claims, testifying not only of a number of cases in the sphere of everyday life, but also of socio-legal peculiarities, are shown. The presence of a constantly working Jury is one of the most important features, which is undeniable for a Cornish Justice in Eyre. Records, narrating about taking an oath by twelve «trustworthy people», conducting preliminary inquisition on every plea, presenting in the court every litigation case, listening to both plaintiffs and defendants, instructing clerks to write down their names as well as the names of pledges, testify to sufficient civility and the order of the procedure. Surely, it’s difficult yet to say about effectiveness of a new system of justice, including signs of the procedure reception by manorial and hundredth justice. Many features of legal development of the period will make up a further research perspective in the sphere of socio-legal daily life of medieval England.
Studiosus ad scribendum: For the 75th Anniversary of Vladimir I. Mazhuga
Authors: Aurov Oleg
Published: September 2024

The article deals with the biography and the academic merits of Vladimir I. Mazhuga (born 15 of April, 1949), a prominent modern Russian specialist in medieval studies and Leading Researcher of the Saint Petersburg Institute of History, Russian Academy of Sciences. A disciple of some great Russian scholars (in different times his masters were Matvey Gukovskiy (1898-1971), Alexandra Lublinskaya (1902-1980), Maria Sergeenko (1891-1987) and Elena Skrzhinskaya (1894-1981)), Vladimir Mazhuga was a tutor of some modern medievalists like Pavel Krylov, Andrey Kasatov, Alexandra Chirkova, Andrey Karnachev, Ekaterina Denisova, Piotr Shamaro, Gleb Schmidt and some others. The main spheres of Vladimir Mazhugas academic interests are Latin paleography, Diplomatics of medieval acts and Codicology of Latin manuscripts. He studied and connected with the cultural context of the Latin Medieval West some important medieval manuscript materials from the Saint Petersburg collections. Between them were the manuscript versions of the works written by Gregory of Tours, Paul Orosius, Hrabanus Maurus and some other medieval writers. His studies in these spheres were logically connected with some problems of linguistics studied by him (history of Ancient grammar and textbooks, biographies of Roman grammatists, historical phonetics etc.). In the same time, he dealt with some other spheres like history of medieval culture and history of Roman law (mainly of the medieval period). His main studies in medieval culture are about the symbology of Medieval City and the role of the Christian Church as a main custodian of Ancient Culture inheritance in the Middle Ages. As a historian of Roman law Vladimir Mazhuga worked over some important Saint Petersburg medieval Latin manuscripts of Roman law texts (like Justinian Institutions and Digesta) and he studied the theoretical works of famous medieval Italian jurists like John Bassianus (died before 1194) and Bartolus de Saxoferrato (1313-1357). In the same time V Mazhuga researched some problems of Latin legal terminology, which was made using the methodology of linguistics. Vladimir Mazhuga's studies in history of Saint Petersburg School of medieval studies must be specially emphasized because he continues some best traditions of this School like scholar and tutor in the same time. He continues to work hard and fruitfully, so the citied conclusions about Mazhuga's academic merits and inheritance have a previous character.
The Impact of Working Capital Management on Financial Performance: Evidence from Sokoine University of Agriculture
Authors: Ninga Francis Mathias , Naho Alexis
Published: September 2024

This study aims to investigate the effects of working capital management (WCM) components on financial performance of Sokoine University of Agriculture (SUA), focusing on how variations in the Average Collection Period (ACP), Average Payment Period (APP), Inventory Conversion Period (ICP), and Cash Conversion Cycle (CCC) influence financial performance measured in Gross Operating Profit (GOP). The study adopted a longitudinal research design utilizing a time series data from SUA’s annual financial statements covering the fiscal years 2013/14 to 2022/23. A multiple linear regression analysis was conducted to assess the effects of the WCM components on GOP, providing a comprehensive understanding of their financial implications. From the analysis, it was revealed that lnACP and lnCCC are negatively associated with GOP, indicating that delays in receivables collection and extended cash conversion cycles diminish financial performance. Conversely, lnAPP is positively related to GOP, suggesting that longer payment periods for liabilities can enhance financial performance. A longer lnICP also negatively impacts GOP, underscoring the need for effective inventory management. Moreover, this study offers fresh insights into the financial management practices at SUA, highlighting the significant effect of WCM on institutional profitability. By providing evidence of how different components of WCM affect financial outcomes, it delivers practical recommendations for improving financial performance through strategic management of working capital. The research contributes valuable knowledge to both academic and practical discussions on financial management in educational institutions.
The Impact of the Omnibus Law on Industrial Relations in Indonesia During the Covid-19 Pandemic: A Qualitative Analysis
Authors: Balahmar Ahmad Riyadh Umar
Published: September 2024

The Covid-19 pandemic since 2020 until now has had a tremendous impact on socio-economic life in Indonesia. Many companies have laid off their employees on the pretext of a decrease in company production affected by the Covid-19 pandemic. On the one hand, the Indonesian government in October 2020 has passed the Omnibus Law which is still controversial. This study aims to explain the industrial pattern in handling employment after the enactment of the Omnibus Law during the Covid-19 pandemic. By using eight informants as research subjects through purposive sampling techniques, this qualitative study collected data through in-depth interviews related to the topic. The results of the study show that before the enactment of the Omnibus Law during the pandemic, the conditions focused on the problem of "rights disputes" including the payroll system, deductions, and employee SP3 which were considered unfair. However, after the enactment of the Omnibus Law, the problem refers more to "interest disputes" between companies and workers to defend their respective interests. This finding has significance for policy makers and practitioners in industrial relations. Governments and companies must understand the transition from rights disputes to interests disputes to develop more inclusive policies and minimize conflicts. Companies must also be more transparent in managing human resources and paying attention to workers' rights to improve fairness and stability of the industry.
