¿Cuáles son los Efectos Emocionales y Psicológicos que ha Causado el Divorcio de los Padres en los Hijos Jóvenes?
Authors: Villalobos Rosado Leslye Daynelle
Published: September 2024

La presente investigación examina los efectos emocionales y psicológicos del divorcio en los hijos. El estudio se enfoca en jóvenes de 18 a 24 años que han experimentado el divorcio de sus padres, buscando identificar los rasgos desadaptativos que afectan su adaptación biopsicosocial. La investigación justifica su relevancia basándose en el aumento significativo de los divorcios en México, con un incremento del 61.4% de 2020 a 2021. El estudio utiliza una metodología exploratoria y descriptiva, aplicando encuestas digitales y entrevistas profundas para recolectar datos cualitativos. Los resultados previos indican que una mayoría de los jóvenes no recibió apoyo psicológico durante el proceso de divorcio, lo que resaltó la falta de redes de apoyo y el desconocimiento de sus propias emociones. Aunque un porcentaje considerable reportó no haber sido afectado en áreas clave de su vida, un 24.2% redujo su energía y un 9.7% vio afectado su rendimiento escolar. El estudio concluye que es esencial la intervención temprana mediante psicoterapia para mejorar la salud mental y proporcionar herramientas de afrontamiento adecuadas, subrayando la importancia de identificar y tratar a su debido tiempo los rasgos desadaptativos para prevenir trastornos emocionales en los jóvenes afectados por el divorcio de sus padres.

La trombosis valvular no es más que la aparición de un trombo a nivel valvular. La válvula más afectada es la válvula mitral, sin embargo en casos raros puede presentarse a nivel de la válvula aórtica . Las causas más frecuentes se asocian a trombofilia, la cual es una condición que altera la coagulación de la sangre, ya sea por causas congénitas o adquiridas, lo que aumenta el riesgo de desarrollar trombosis al igual que los pacientes post prótesis de válvula nativa. La antitrombina, es una glicoproteína que previene la conversión de protrombina en trombina y de fibrinógeno en fibrina, detiene la finalización de la formación del coágulo, reduce la secreción de citocinas, minimiza las interacciones entre neutrófilos y endotelios y disminuye la activación de plaquetas y células endotelial lo que evita la formación de un coágulo.  La trombosis valvular aórtica en pacientes con deficiencia hereditaria de antitrombina (AT) es una condición infrecuente pero complicada, que plantea retos importantes en su manejo, estudios  actuales proponen como medida eficaz para el tratamiento la combinación de anticoagulantes, empezando con heparinas y luego utilizando anticoagulantes orales como la warfarina, con la posibilidad de añadir antitrombina exógena si hay resistencia a heparinas para impactar positivamente y reducir la morbimortalidad del paciente y evitar que el déficit de antitrombina sea un detonante importante en la formación de trombos . Por lo tanto, el objetivo de esta revisión sistemática es indagar sobre causas de la trombosis valvular aórtica, más puntualmente aquella dada por déficit de antitrombina.

Published: September 2024

The transportation industry plays an integral role in the daily lives of Indonesians. However, it also contributes to environmental degradation, particularly in terms of airquality, which impacts public health. This research applies the Life Cycle Assessment (LCA) method, a sustainability matrix, to gauge the environmental impact of Jakarta'spublic transportation system. Our study aims to identify car emissions and understand the environmental consequences they pose. The research was scoped to examine both the raw materials and energy input and the resultant emissions. Specifically, we analyzed the electricity consumption of Jakarta's MRT, Bus Trans Jakarta, and online taxi services. We utilized the LCA methodology and the SimaPro 9.1 software for assessment. Prior research data were incorporated to enhance the accuracy of our LCAmodel. A notable observation is the decline in public transportation usership since the onset of the COVID-19 pandemic. Current health protocols allow only half the usual passenger capacity, compounded by a sluggish economy. Our findings reveal that the Mass Rapid Transit (MRT)'s CO2 emissions, at 0.019 kg/passenger/kilometer, are significantly lower than that of the BRT at 0.036 kg/passenger/kilometer. One recommendation to further reduce emissions is to transition buses from diesel to compressed natural gas (CNG) fuel. However, public adoption of these changes will largely hinge on individual preferences.

Published: September 2024

A deep learning approach to analyze the sentiment of user tweets is proposed to provide recommendations for movies and TV shows on streaming services. Recognizing the importance of implicit user feedback on social media, we focus on how viewers express their opinions on Twitter regarding drama series and films. To achieve this, we collect Twitter data using a Python library and REST API, then employ natural language processing techniques like TextBlob and VADER to extract show names and analyze sentiment. Our deep learning model demonstrates positive results with strong accuracy and minimal error rates. The proposed approach targets social media users who also subscribe to streaming services and opens potential applications in diverse domains like purchasing preferences, political opinions, and educational choices.
Low-Cost Automatic Tester of PLC Functions
Authors: Chuvanich Suvalee
Published: September 2024

In smart industries, a Programmable Logic Controller (PLC) is necessary to control system functions that confirm to work according to requirements. Furthermore, the testing of PLC functions should be carried out in a very short time with very good accuracy and high reliability, but at the lowest cost possible. This paper presents the Automatic Test Equipment (ATE) for PLC functions. The objective of this paper is to design low-cost ATE from commercially off-the-shelf (COTS) with ease of testing. A model-based systems engineering approach is used to design the tester. The ATE design uses the open-source Capella tool, which supports the Architecture Analysis and Design Integrated Approach (ARCADIA) method. The structural elements of the ATE system are the test controller, the switching relays, the system software, and the Human-Machine Interface (HMI), which is used to display the test results. The test controller executes the test program and controls the inputs of the PLC under test using the test patterns via switching relays. The responses from the outputs of the PLC are sent to the inputs of the test controller and compared with the expected responses. The results of PLC function testing are displayed on the HMI. The results show that the maximum speed of the ATE is 10 ms/pattern, and the total cost is under 140 USD.

Exploration of the Impacts of Hall Effect, Dufour Effect, and Heat Source on Parabolic Flow over an Infinite Vertical Plate in the Presence of Rotation, Chemical Reaction, and Radiation in a Porous Medium
Authors: D LAKSHMIKAANTH , A. Selvaraj , S. Bhavani
Published: September 2024

The article focuses on the influence of Hall current, radiation, heat source, and Dufour effects on the unsteady magnetohydrodynamic (MHD) natural convective parabolic flow over a vertical plate fixed within a porous medium. The study involves examining the heat transfer and substance accumulation dynamics when an incompressible fluid flows over a vertically oriented plate. The plate is uniformly heated and undergoes increased velocity due to rotational motion. The researcher applied the Laplace Method to find solutions for the relevant mathematical equations. In this analysis, specific parameters were considered, including Prandtl, Schmidt, Grashof values for heat transfer, and the Grashof value for substance accumulation. The results indicated that factors such as heat source, Hall current, permeability, and Grashof values lead to a corresponding increase in fluid velocity. Conversely, an increase in radiation levels is associated with a decrease in fluid velocity. Temperature, on the other hand, rises with a higher heat source and decreases with an increase in radiation levels.

Determinants of bank profitability in Vietnam: a focus on financial and COVID-19 crises
Authors: Nguyen Phan Dinh
Published: September 2024

This research examines the determinants of banks’ profit by employing the GLS, GMM and SEM regression method for 574 observations obtaining from 35 banks functioning in Vietnam between 2005 and 2022. Our evidence indicates that non-performing loans, deposit, loan, capital, operating cost, provisions, bank size, Covid-19 pandemic, inflation, economic growth, deposit rate, credit risk, exchange rate and ownership are key factors affecting bank profitability. Our findings show that the global crises are negatively associated with ROA and NIM while they are negatively related to ROE. The COVID-19 has a stronger effect than the financial crisis. Both crises play a moderating role in bank profitability. This research expands the existing literature by analyzing the impact of crises and the moderating effects, crisis comparison, and ownership effect which have not been done so far, to our best knowledge. This research also extends the literature by offering additional understandings about the determinants of bank profitability in emerging economies. Different from the previous studies, our dataset including foreign banks helps us analyze all banks. The investigation of factors affecting profitability also assists banks in regulating and supporting prudential supervisions carefully.
The Age-dependent Vertical Actions of Young Stars in the Galaxy

Published: September 2024

Stars in the Galactic disk are born on cold, nearly circular orbits with small vertical excursions. After their birth, their orbits evolve, driven by small- or large-scale perturbations in the Galactic disk’s gravitational potential. Here, we study the vertical motions of young stars over their first few orbital periods, using a sample of OBA stars from Gaia E/DR3, which includes radial velocities and ages τ from LAMOST. We construct a parametric model for the time evolution of the stellar orbits’ mean vertical actions J

as a function of Galactocentric radius, R
GC. Accounting for data uncertainties, we use Markov Chain Monte Carlo analysis in annuli of Galactocentric radius (R
GC) to constrain the model parameters. Our best-fit model shows a remarkably linear increase of vertical actions with age across all Galactocentric radii examined. Orbital heating by random scattering could offer a straightforward interpretation for this trend. However, various other dynamical aspects of the Galactic disk, such as stars being born in a warped disk, might offer alternative explanations that could be tested in the future.
Streaming Torque in Dust–Gas Coupled Protoplanetary Disks
Authors: Hou Qiang , Yu Cong
Published: September 2024

We investigate the migration of low-mass protoplanets embedded in dust–gas coupled protoplanetary disks. Linear calculations are performed with respect to the Nakagawa–Sekiya–Hayashi (NSH) equilibrium within a shearing sheet. We find that the dusty quasi-drift mode dominates the dynamical behaviors in close proximity to the protoplanet. This mode exhibits an extremely short radial wavelength, characterized by a dispersion relation of

. The emergence of this mode leads to a wake with a short radial length scale ahead of protoplanets, contributing to a positive torque, termed as “streaming torque” (ST). Furthermore, both Lindblad torque and corotation torque are affected by the NSH velocity. The total torque and planetary migration are contingent upon the coupling strength between dust and gas. In most scenarios, ST predominates, inducing outward migration for planets, thereby addressing the issue of rapid inward migration in their formation paradigm.
Eyelid tumors in children over a 10-year period
Authors: Balchev Georgi
Published: September 2024

Introduction: Eyelid tumors in children are rare and, fortunately, mostly benign. Reconstruction after excision of these tumors is an extremely responsible procedure, considering the early age of the patient.

Aim: To analyze the incidence and location of malignant and benign tumors in children up to 18 years of age over a period of 10 years.

Materials and methods: We conducted a retrospective study of 29 eyes from a cohort of 450 eyes with tumors operated on in our clinic between 2010 and 2019. Of all tumors of the eye and adnexa, only tumors of the eyelids were considered. All tumors were histopathologically examined after their surgical removal.

Results: Eyelid tumors in children account for 6.4% of the tumors studied in all age groups, and 0.2% of them are malignant. The ratio of women to men is 62% to 38%, with most of them residing in cities. The most common eyelid tumors in children are cysts (47%), followed by papillomas (17%) and nevi (10%). The distribution on the eyelid is as follows: medially located 31%, centrally 45% and temporally 24%.

Conclusion: Eyelid tumors in children prefer the female sex. Malignant tumors of the eyelids are rare. The average size of tumors is about 4-6 mm. The duration of the disease directly correlates with the size of the tumor. For tumors of the lower eyelid, a doctor is consulted earlier than for tumors of the upper eyelid. Inflammatory reaction around the tumor is more common in the right eye.
Primary acquired nasolacrimal duct obstruction – epidemiology, clinical signs and surgical treatment
Authors: Valcheva Krasina P. , Murgova Snezhana V.
Published: September 2024

Aim: The aim of this study was to discuss the epidemiological aspects, clinical picture and the mode of surgical treatment in patients with primary acquired nasolacrimal duct obstruction (PANDO).

Patients and methods: Between 1995 and 2016, the Eye Clinic at the University Hospital in Pleven carried out a retrospective analysis on 28 PANDO patients who underwent external dacryocystorhinostomy (DCR). The effect of surgical treatment was assessed based on a history of watery eyes and the tear drainage system’s patency. Only eight of those patients responded to a follow-up examination after surgery for the purposes of this study.

Results: The demographics of the evaluated patients were as follows: 17.9% were male, 82.1% were female, 78.6% lived in the city, 92.9% had one impaired eye, and 7.1% had bilateral PANDO. The mean age of the patients at operation was 43.3±5.7 years (SD=14.6). All patients experienced epiphora and discharge; 63.3% had redness of the skin around the lacrimal sac, and 33.3% had episodes of acute dacryocystitis prior to surgery. The surgical success of external DCR was evaluated in nine eyes among the eight patients who responded to the postoperative review. The results showed that the operation was successful in 55.6% of these patients, whereas in 11.1% it had a doubtful effect, and in 33.3% it was not successful.

Conclusion: PANDO primarily affects women in their middle years. Cases that are unilateral are more common. External DCR is performed in patients with prolonged epiphora and purulent discharge. 55.6% of the cases are successful. In spite of the outcome, patients expressed great satisfaction with the cosmetic outcome and the disruption of their everyday lives caused by the watering of the eyes.
Temochloa (Poaceae, Bambusoideae), a newly-recorded bamboo genus for China and Vietnam, with new taxa and a re-interpretation of flowering structures
Authors: Cai Zhuo-Yu , Zhang You-Yuan , Tong Yi-Hua , Vu Tien Chinh , Xia Nian-He
Published: September 2024

Neomicrocalamus and Temochloa are closely-related genera for which ‘inflorescence’ structures were incompletely understood and difficult to reconcile. After re-examining the inflorescence morphology, the so-called ‘spikelets’ of both genera as described should instead be recognised as pseudospikelets with mostly inactive axillary buds. The new bamboo taxa, comprising two varieties of a new species, are placed in Temochloa, representing a new genus record for China and Vietnam.

Published: September 2024

After a comprehensive taxonomic assessment of descriptions/ illustrations of all known (118) species of the spider mite genus Schizotetranychus Trägårdh (Acari: Prostigmata: Tetranychidae), five species groups are proposed based on the number of tactile setae on tibia II in female, i.e., vermiculatus with four setae (four spp.), schizopus with five setae (52 spp.), spireafolia with six setae (10 spp.), asparagi with seven setae (20 spp.), and bambusae with eight setae on tibia II (22 spp.). The species group schizopus is further divided into three species subgroups based on tactile setae on tibia I: schizopus with eight/ nine setae (21 spp.), andropogoni with seven setae (26 spp.), and taquarae with six tactile setae excluding the solenidion on tibia I (five spp.). Eight Schizotetranychus species were not assigned to any species group because of brief descriptions and/ or illustration and without information on the number of tactile setae on tibiae I and II. Moreover, two Schizotetranychus species, S. gausus Baker & Pritchard and S. luculentus Tseng that have six setae/ structures including a spinneret and a solenidion on the palp tarsus, are provisionally transferred to the genus Stigmaeopsis Banks. Finally, keys to species groups and subgroups of the world species of Schizotetranychus are provided.

Embedding the Retinal Flap in the Original Retinal Hole as a Treatment for Retinal Detachment of the Posterior Pole
Authors: Terasaki Hiroto , Sakamoto Taiji
Published: September 2024

Background and Objective

Rhegmatogenous retinal detachment (RRD) of the posterior pole accounted for only 3.5% of all RRD cases in Japan, with most being macular hole retinal detachments, which are difficult to treat. Retinal detachment of the posterior pole not caused by a macular hole is rare. Herein, we report a case of RRD of the posterior pole that was successfully treated by embedding the original retinal flap with a bridging vessel into the retinal hole.

Patients and Methods

A 56-year-old woman with a preoperative visual acuity of 20/100 was diagnosed with RRD of the posterior pole. We sealed the original retinal tear by embedding the retinal flap within the tear.

Results

One year after surgery, blood flow was maintained in the bridging vessels and peripheral retina.

Conclusion

This technique may be useful for treating retinal detachment caused by retinal tears of the posterior pole.

Published: September 2024

Seismic interpretation is primarily concerned with accurately characterizing underground geological structures & lithology and identifying hydrocarbon-containing rocks. The carbonates in the Netherlands have attracted considerable interest lately because of their potential as a petroleum or geothermal system. This is mainly because of the discovery of outstanding reservoir characteristics in the region. We employed global 3D seismic data and a novel Relative Geological Time (RGT) model using artificial intelligence (AI) to delve deeper into the analysis of the basin and petroleum resource reservoir. Several surface horizons were interpreted, each with a minimum spatial and temporal patch size, to obtain a comprehensive understanding of the subsurface. The horizons were combined with seismic attributes such as Root mean square (RMS) amplitude, spectral decomposition, and RGB Blending, enhancing the identification of the geological features in the field. The hydrocarbon potential of these sediments was mainly affected by the presence of a karst-related reservoir and migration pathways originating from a source rock of satisfactory quality. Our results demonstrated the importance of investigations on hydrocarbon potential and the development of 3D models. These findings enhance our understanding of the subsurface and oil systems in the area.
New traveling wave solutions, phase portrait and chaotic patterns for the dispersive concatenation model with spatio-temporal dispersion having multiplicative white noise
Authors: Shi Da , Li Zhao , Chen Dan
Published: September 2024

This article studied the new traveling wave solutions of the cascaded model with higher-order dispersion effects combined with the effects of spatiotemporal dispersion and multiplicative white noise. In the process of exploring traveling wave solutions, a clever combination of the polynomial complete discriminant system was used to discover more forms of traveling wave solutions for this equation. In order to better observe and analyze the propagation characteristics of traveling wave solutions, we used Maple and Matlab software to provide two-dimensional and three-dimensional visualization displays of the equation solutions. Meanwhile, we also analyzed the internal mechanism of nonlinear partial differential equations using planar dynamical systems. The research results indicated that there are differences in the results of different forms of soliton solutions affected by external random factors, which provided more beneficial references for people to better understand the cascaded model with higher-order dispersion effects combined with the effects of spatiotemporal dispersion and multiplicative white noise, and helped people to more comprehensively understand the propagation characteristics of optical solitons. The solution method in this article was also applicable to the study of other nonlinear partial differential equations.

Gynecomastia is a benign glandular proliferation that can affect adolescents causing significant psychological discomfort. Generally, it is idiopathic but underlying endocrinological conditions must be excluded. Different surgical techniques are available, the surgical correction with subareolar incision achieves the goal of satisfactory aesthetic result for patients. We studied all patients treated for gynecomastia in two centers of pediatric surgery. After collection of a detailed family history, we evaluated the presence of early onset of puberty, congenital abnormalities of the external genitalia, use of drugs, eating habits and the presence of genetic disorders. Laboratory tests and ultrasound were made to exclude endocrinological disorders. The surgical treatment was performed by a subareolar incision with gland and adipose tissue excision. A Body - Q chest module to evaluate patient satisfaction has been proposed to everyone before and after surgery. 47 adolescents with median age of 15 years were surgically treated. Three presented endocrinological disorders. Grade of gynecomastia for surgery was: III in 40 patients and IIb in 7 patients. Postoperative complications occurred in 5 patients. The Body - Q chest module was completed by 42 patients and showed good results for all points analyzed, except for social feelings. Gynecomastia in adolescents can be surgically treated with subareolar incision, reporting good aesthetic results and low incidence of complications. Specific tests are useful to assess patient satisfaction.
Usefulness of fasciocutaneous flaps for revision of below-knee amputation stumps
Authors: Kala Prakash Chandra , Dave Aniket , Dixit Pawan Kumar , Karmakar Shilpi , Katrolia Deepti
Published: September 2024

Below-knee lower limb amputations are commonly performed for multiple indications. These vary across age groups, with trauma being the most common indication among young adults. Although below-knee amputations are disabling, decent functional outcomes can be expected with an adequately long tibial stump and a good prosthesis. In our series, the amputation stump was debrided per the surgeon’s clinical judgement. The fasciocutaneous flap (free or pedicled) was planned according to the patient’s individual needs and the flap’s feasibility at the surgeon’s discretion. A fasciocutaneous flap cover helps preserve the length of the below-knee amputation stump, resulting in better ambulation. A flap cover at the amputation stump is a better alternative to revising the level of amputation. Higher-level amputations have much worse ambulation rates and require more energy for efficient ambulation with prosthesis.

After years of programmatic inaccessibility, in 2019–2020 the Sudan Federal Ministry of Health Trachoma Control Program conducted population-based trachoma surveys in three localities (districts) in North Darfur state, Sudan. These baseline surveys were to determine the prevalence of trachomatous inflammation–follicular (TF) among children aged 1–9 years and to further use serological markers to understand the historical trachoma burden within this mass drug administration (MDA)–naive area. Trained and certified graders collected trachoma clinical data, and trained nurses collected dried blood spot (DBS) samples. The DBSs were assayed on a multiplex bead array for antibody responses to the Chlamydia trachomatis antigens Pgp3 and CT694. Across the three localities, 3,613 individuals aged 1–9 years and 3,542 individuals aged ≥15 years were examined for clinical signs, and 8,322 DBSs were collected. The prevalence of TF among children aged 1–9 years was endemic (≥5%) in two localities (El Seraif, 15.6%, and Saraf Omrah, 11.0%) and below the TF elimination threshold (<5%) in the third (Kotom, 1.4%). The Pgp3 seroprevalence among children aged 1–9 years was 34.1% in El Seraif, 35.0% in Saraf Omrah, and 11.0% in Kotom. Locality prevalence results were similar for Pgp3 and CT694. Seroprevalence increased with age in all three localities. Serological data collected within these surveys demonstrate that all three localities have had a long history of exposure to Chlamydia trachomatis and that two of the three localities require MDA to reach elimination as a public health problem threshold.

Effective inventory management techniques are crucial for optimizing the flow of goods across the supply chain. This study aims to determine the moderating effect of process innovation on the relationship between inventory management techniques and supply chain efficiency. A survey method was used in this study. The data collected was cross-sectional, meaning it was gathered at a single point in time. There is a strong positive effect of supplier relationship management on supply performance. Additionally, employee commitment positively and significantly affects supply performance. However, the effect of employee commitment on the relationship between supplier relationship management and supply performance is not statistically significant. When effectively implemented, inventory management techniques can be seen as unique resources specific to an organization. This study aims to contribute to the existing body of knowledge by providing empirical evidence on the interdependence of inventory management techniques, process innovation, and supply chain efficiency.
Senior management's influence on supplier selection and procurement performance

Published: September 2024

This thesis investigates the influence of senior management on the supplier selection process and its impact on procurement performance. Senior management's role in shaping procurement practices is critical, as their support and strategic direction significantly affect the efficiency and effectiveness of supplier selection. The study explores how managerial commitment moderates the relationship between supplier selection and procurement performance. The research employs a comprehensive analysis based on data collected from 185 respondents, including operations managers, procurement officers, risk managers, supply chain managers, and warehouse managers from manufacturing companies in Ghana. Using Exploratory Factor Analysis (EFA) and descriptive statistics, the study examines various dimensions of supplier selection, senior management support, and procurement performance. Findings reveal that senior management's involvement positively influences procurement performance by emphasizing key criteria in supplier selection, such as financial status, quality systems, and delivery capabilities. Specifically, factors like supplier reputation, pricing, and geographic location were identified as critical for effective supplier selection. Senior management's support for procurement practices, including regular performance evaluations and sustainability assessments, was also found to significantly impact procurement outcomes. However, while senior management support enhances procurement performance, it does not moderate the relationship between supplier selection and performance. The results suggest that while strategic management and support are crucial, they operate independently of the supplier selection process in affecting procurement performance. This study provides valuable insights for organizations seeking to improve procurement practices by highlighting the importance of both strategic supplier selection and robust senior management support. Recommendations include enhancing senior management's role in procurement strategies and focusing on critical supplier performance criteria to optimize procurement outcomes.
Refugee Protection in Kenya
Authors: Amatsimbi Herbert
Published: September 2024

This journal article explores the framework for refugee protection in Kenya. The country has hosted refugees from neighbouring East African countries, primarily due to its perceived political stability. The refugee situation is marked by significant hardship, affecting not only the refugees themselves but also the host nation. This scenario places considerable strain on the financial and physical resources of the host nation and necessitates substantial efforts from the international community to provide aid to those in need. In response to the refugee crisis, Kenya has adopted several policies to ensure compliance with international standards for refugee protection. This article evaluates how effectively Kenya’s Refugee Act of 2021 has been domesticated and upheld in line with internationally acknowledged and obligatory durable solutions to the refugee problem. A descriptive literature review was employed to collect, organise, analyse, and present the relevant data. The findings posit that although Kenya has made notable progress in establishing regulatory frameworks to protect refugees, the goals of refugee protection remain unfulfilled. Even with the enactment of the Refugee Act of 2021, refugees in Kenya still face numerous challenges related to their protection. The article contends that the key to resolving the refugee crisis in Kenya hinges on the diligent implementation of the durable solutions. This research contributes to the broader discourse on refugee protection worldwide, with a particular emphasis on the Kenyan context.
Investigation of Status and Determinants of Rural Household Food Security in Morogoro Rural District.
Authors: Mberwa Elias , Mwakibete Anne
Published: September 2024

Food security remains a critical challenge in rural areas, particularly in Morogoro Rural District, where households face various socio-economic and environmental pressures. Therefore, this study examines the determinants of food security in Morogoro Rural District using a cross-sectional research design. A sample size of 377 households was selected, and data were collected through structured questionnaires. The analysis employed a Probit model to identify key factors influencing food security. The results revealed that household income, gender of the household head, climate change, and household size significantly affect food security, with higher income, male-headed households, and larger household sizes being positively associated with food security, while climate change negatively impacts it. These results suggest that economic stability, gender empowerment, and climate resilience are crucial for enhancing food security, while household dynamics also play a significant role. The findings highlight the need for targeted interventions that address these determinants to improve food security in rural areas.
Nowołacińskie heroidy jezuickie. Mutacje i metamorfozy
Authors: Buszewicz Elwira
Published: September 2024

The aim of the text is to describe the varieties and transformations of the literary genre inspired by Ovid’s Heroides, which occurred in Jesuit works in the early modern period (sixteenth and seventeenth centuries) within a specific geographical area, i.e. especially in Germany and the Netherlands. These considerations are preceded by a short reflection on Christian heroides created by humanist authors in the sixteenth century.

The paper discusses mainly volumes covering entire collections containing numerous sacrae heroides and also presents some illustrative examples. The most important authors for the implementation of the genre are presented: Jakob Bidermann, Jean Vincart and Jakob Balde, as well as (more briefly) Balduin Cabillavius.

The concepts of each collection and their ideological dominants are discussed. The analyses are complemented by fragments of some elegies quoted in the original along with the Polish translation made by the author.
„Kolacyja przyjacielska” Jakuba Niemojewskiego z jezuitami poznańskimi – glosa terminologiczna
Authors: Ryczek Wojciech
Published: September 2024

Ultimately unsuccessful attempts to organize a public dispute with the Jesuits from Poznań in 1574–1575 forced Jakub Niemojewski (d. 1586), a vigorous reformer and talented orator, to write and publish “diatribe or friendly discussion” (“diatribe albo kolacyja przyjacielska”) in 1577. Due to a Jesuit intervention, to whom the first pages of the printed text were given, the publication was immediately suspended. They had the printer’s workshop destroyed, he was sentenced to whipping in the pillory, and the books were finally burnt. Despite the fact that only over a dozen pages of the text have survived, it may be interesting for historians of rhetoric for at least two reasons. Firstly, it is associated with the beginnings of anti-Jesuit literature in the Polish-Lithuanian Commonwealth, written to confine increasing influences of this expansive religious order. Secondly, it may be treated as an intriguing case of debate on the art of debate or negotiating the initial conditions for public dispute, which reveal significant differences in the understanding of its nature, form, and purpose.

Taking into account this meta-rhetorical dimension of Niemojewski’s polemic, the paper aims at specifying the meaning of the title term “discussion” (“kolacyja”) as a semantic equivalent of “diatribe” in three interrelated contexts: art of argumentation (collatio argumentorum), Erasmian model of polemic on theological questions (collatio Erasmiana), and a topos of “friendly” discourse (collatio amica).

Published: September 2024

The climatic conditions and geographical location of Fergana, one of the most important basins of Turkestan, have brought the region to the forefront throughout history. The region has been a place where not only foreign powers but also Turkish tribes constantly raided. The Khanate of Kokand, which ruled in Fergana between 1709 and 1876, maintained its political power in the region for a long time and also contributed to the development of the city of Kokand with its construction activities. The city, which showed great development in a short time, became the capital of the khanate. Different building types such as mosques, madrasahs, tombs, bridges, baths, castles and palaces were built in Kokand. The city of Kokand became the center of science, culture and art of its time. Among the building groups in the city, tombs have a special importance because they are sacred places and are constantly visited. Among the surviving works of the Kokand Khanate in Kokand, Dahma-i Shahan and Madari Khan Tombs are remarkable in terms of their architectural features. It is known that Dahma-i Şahan Tomb belongs to the khans, and Madari Khan Tomb belongs to the female representatives of the khanate. In this study, Dahma-i Shahan and Madari Khan Tombs, which reflect the architectural features of the Kokand Khanate, are examined in detail in terms of plan, material and decoration features. Keywords: Kokand Khanate, Kokand, Tomb, Dahma-i Shahan, Madari Khan.
