Four quartz monzonite – granite intrusions forming the Sorsakoski granite lithodeme, are found within the Raahe-Ladoga suture zone in Central Finland. The prevailing potassium feldspar megacrystic quartz monzonites and granites form a bimodal association with diorites and gabbros. The granitoids are mainly calc-alkaline, ferroan, per- to metaluminous, and have high Zr and REE contents. Dominant mafic minerals are biotite and hornblende, clinopyroxene and orthopyroxene are locally present. The mafic units display effects of fractionation of clinopyroxene. In our interpretation, these intrusions were emplaced during regional late stages of deformation and post-crystallisation deformation partitioned into major shear zones leaving bulk of the intrusions relatively undeformed. Based on one new (1876 ± 6 Ma) and one pre-existing (1882 ± 5 Ma) U-Pb zircon age determination, the crystallisation age of the granitoids can be assumed at ca. 1880 Ma. Based on mineralogy, petrography, geochemistry, bimodal nature of magmatism and age, we correlate these intrusions to the A-type rocks of the previously described Saarijärvi suite. This shows that the syn-orogenic A-type magmatism extended eastwards beyond the Central Finland Granitoid Complex.

Can we treat idiopathic CTEV without tenotomy? A prospective study
Authors: Pandiyarajan E  , Agrawal Alok Chandra , Garg Deepak Kumar , Yadav Santosh Kumar
Published: June 2024

Tendoachillis tenotomy is the procedure of choice to correct equinus deformity in Ponseti technique. Though Tenotomy is the most frequently done procedure, is associated with complications in 11% to 50% of cases. So, we were in search of an alternative which would have less complication and will give similar results to a standard tenotomy. One such method is Botulinum toxin type A injection into the gastronemius-soleus muscle which causes reversible paralysis of the muscle leading to lengthening of muscle unit, easy manipulation and casting. In our study, we compared the outcomes of Botulinum toxin with tenotomy in the correction of hindfoot equinus in children (<2>0.05) between the two groups in the post-intervention Pirani score and ankle dorsiflexion was seen at 3&6 weeks and 3,6,12 month post intervention. Average dorsiflexion was around 11±1º in both groups upto 1 year post intervention.

Early results shows that Botulinum toxin type A is a good alternative to a routine tendoachillis tenotomy to correct hindfoot equinus in the management of clubfoot by the Ponseti method.
Clinical, radiological and functional outcome following surgical fixation of acetabular fractures
Authors: Vanamail Senthil Narayanan , Vanamail Perumal
Published: June 2024

: Acetabular fractures are commonly caused by high-velocity injuries that can result from falls from heights or motor vehicle accidents. Surgical fixation has been found to result in improved clinical outcomes such as reduced pain, improved range of motion, and improved alignment and stability of the joint. Patients with pelvic injuries often have associated multiple systemic injuries, adding to the overall morbidity and mortality. Treating fractures in the pelvic area involving the acetabulum can be complicated, significantly when displaced. Proper exposure of the acetabulum and rigid internal fixation is necessary to achieve the main goals of treatment, which are to reconstruct the articular surface and promote early mobilization. Closed methods make it nearly impossible to restore the articular surfaces completely and obtain enough stability for early hip motion.

: This study assesses the functional outcome of open surgical fixation of acetabulum fractures involving single or both columns.

: Our study looked at patients over 18 years old with displaced fractures, and we treated them using only two approaches: the Kocher Langenbeck approach and the Modified Stoppa approach. Radiological and functional examinations were performed monthly for the first six months. Postoperative radiological assessments were graded using Matta's criteria, and functional outcomes were assessed using modified Merle d' Aubigné and Postel Hip Score.

: We treated displaced acetabular fractures using only two non-extensile approaches: the Kocher Langenbeck approach and the Modified Stoppa approach. In most cases (67%), we used only one method, except in 7 patients. Our treatment achieved an impressive 85% rate of good to excellent outcomes (18 out of 21). Our study found that the delay in surgery time significantly impacted Merle d' Aubigne scores (P<0.05), leading to complications and lower functional outcomes in complicated cases. The functional and radiological outcomes were also significantly affected by the mechanism of injury, time between injury and surgery, initial degree of displacement, and quality of reduction. Surgical fixation of displaced acetabular fractures can yield better results with good imaging facilities, experienced surgeons, better instrumentation, and good perioperative care. However, further studies with an adequate sample size are needed to validate our findings.

A study on the outcome of acetabular fractures treated surgically found that early surgical intervention and good perioperative care can lead to satisfactory functional outcomes. The study used only two non-extensile approaches and achieved an 85% rate of suitable to excellent outcomes. The study also observed that the mechanism of injury, time between injury and surgery, initial degree of displacement, and reduction quality significantly affected functional and radiological outcomes. However, further studies are needed to validate the findings.

Published: June 2024

Traditionally used extensile lateral approach for treatment of displaced intra- articular calcaneal fractures has reported high rate of soft tissue complications (30%). In attempt to lower the complication rates, various minimal invasive techniques were introduced likes Sinus tarsi approach etc.

To study the clinical & functional outcome of operative treatment of displaced intra- articular calcaneal fractures by STA & ELA.

This prospective study was conducted in a tertiary care teaching center for 1 year from July 2019 to June 2020 following clearance from institutional ethics committee (Human). Sander’s type 2 & 3 closed fracture included and open fractures, sander’s type 1 & 4, extra-articular fracture, severe osteoporotic bone and conditions affect the gait were excluded. 15 patients underwent STA and 15 patients underwent ELA. Clinico-radiological follow-up was done at 2, 6, 12 weeks and 6th month to assessed union, radiological outcome, functional outcome and complications. VAS for pain relief, AOFAS score for functional outcome.

Most were working middle age male mainly due to fall from height and road traffic accidents. Sander’s type 2 and 3 were more common. STA had shorter operative time (54.20 ±4.48mins), less intra-operative blood loss (51.00 ±5.73ml) and less soft tissue complications (13.33%) compared to ELA (operative time = 70.80± 9.05mins, blood loss= 98.00 ±9.2ml, complications = 46.67%). Both groups had 100% union. STA had early pain relieved (at 6th weeks) but VAS score was similar in both groups at final outcome. No difference was observed in radiological parameters and AOFAS score at final follow-up.

STA gives better result than ELA in operative treatment of sander’s type 2 and 3 calcaneal fractures.

Authors: Magadum Sunil Dhondiram , Jasti Ramprasad , Mohandas Prithvi , Nandipalli Akilesh Kumar , Ragavan Mahesh Karthik
Published: June 2024

: Segmental tibia fractures are caused by high-velocity trauma. They are often associated with soft tissue and other systemic injuries leading to higher complications rates. In this study, we aimed to analyse the clinical, functional and radiological outcome including the incidence of malunion in these fracture following suprapatellar nailing.

We retrospectively analysed 55 patients from January 2016 to January 2020 who underwent suprapatellar nailing using two different nailing systems at a single tertiary care trauma centre. Periodic follow-ups were done to evaluate the union rates, the functionality of the limb and associated complications like malunion.

Average time of union overall was 26 weeks with closed fractures healing at an average of 22 weeks and open fractures healing at an average of 33 weeks. The average functional score using LEFS at the end of one year was 86% with 89% of the patients having good to excellent functional outcome. We had 22 cases of the delayed union out of which only 5 cases required secondary procedures to aid in the union. Malalignment was noted in 1 case. All fractures included in this study eventually healed at the final follow up. Anterior knee pain was reported in 3.6% of the cases.

: We recommend suprapatellar nailing in all segmental tibial fractures irrespective of the type of injury as it reduced the rate of malunion and anterior knee pain, without compromising on union rates and functional outcome.

Authors: Augustus Megan , Ali Allan , Beharry Allan , Armorer David , Lousaing Derrick
Published: June 2024

Giant Cell Tumors (GCTs) of bone are primary bone tumors that are benign. They are biologically aggressive and have metastatic potential after malignant transformation. There have been several cases of GCTs described in the medical literature. The management of juxta-articular GCTs in the young population is one of the greatest challenges in orthopaedic oncology. Amputations were once the standard treatment for malignant bone tumours. Advances in orthopaedic surgical techniques and bioengineering have made limb-sparing surgery a viable treatment option. Limb- salvage surgery is considered safe and is routinely undertaken for 90% of cases of bone tumors. The advances in orthopaedic surgical techniques and bioengineering of prosthesis have made this a viable option for these complex cases.

Staging is performed using the Campanacci Radiographic Classification System and this is based on the radiological findings of the GCT. This staging system is used to guide the planning of the initial surgical management. Campanacci Stage III GCTs are aggressive lesions thus En bloc resection and reconstruction have been proposed as the choice of treatment. This is done with the goal of joint preservation as well as reducing the risk of recurrence.

This case report highlights the challenges in the management of a Campanacci Grade III GCT of the distal femur. A mega prosthesis or endoprosthesis is a viable first-line treatment for oncological patients with significant bone and soft tissue loss. Oncological clearance was achieved then by the customized megaprosthesis was assembled and set in place. Procurement of this custom-made megaprosthesis during the COVID-19 pandemic was particularly challenging.

Published: June 2024

Immature/total neutrophils (I/T) ratio is a simple and inexpensive method used as an early sign of bacterial infection. Meanwhile, the S100B protein is found in glial cells and functions as a neuroprotection. Then, the interleukin-10 cytokine acts as an anti-inflammatory cytokine during infection. In addition, the NEWS2 score is used to see the early and fast changes in patients with sepsis. The purpose of the study was to prove the correlation between the I/T ratio, S100B, IL-10, and NEWS2 score in patients with sepsis. A cross-sectional study was conducted on 34 patients with sepsis from September 2020 to February 2021. I/T ratio was calculated in 100 leukocytes from microscopic blood smear preparation. Levels of S100B and IL-10 serum were measured using the ELISA method. Pearson correlation test was used for normally distributed data, and the Spearman correlation test was utilized for abnormally distributed data. Correlation test between I/T ratio, S100B, and IL-10 with NEWS2 score respectively showed values of r=0.58; P=0.01, r=0.36; P=0.03, and r=0.39; P=0.02, in which P<0.05. There was a moderate positive correlation between I/T ratio and NEWS2 score, a weak positive correlation between S100B and NEWS2 score, and a weak positive correlation between IL-10 and NEWS2 score.

Published: June 2024

The Kansas City Cardiomyopathy Questionnaire (KCCQ) has been developed to measure the health status of Congestive heart failure (CHF) patients. This study aimed to translate KCCQ into a Persian version and assess its validity and reliability. We used a forward-backward procedure to translate the questionnaire. In a cross-sectional study, 150 CHF patients and 50 healthy subjects over 30 years old were selected to assess the reliability and construct validity of the instrument. The face and content validity were used for the questionnaire's validity. The validity was examined on a population of patients with CHF using the Persian version of the Minnesota Living Heart Failure Questionnaire (MLHF) health survey. Calculation of the Intraclass correlation coefficient (ICC) and Cronbach's alpha was done to evaluate the questionnaire's reliability. Test-retest reliability was examined by re-administering the KCCQ after 2 weeks. Test-retest results demonstrated that the Persian version has excellent reliability (ICC for all domains was higher than 0.93, P≤0.000). Internal consistency was found by Cronbach's alpha to be 0.86 for the clinical summary and 0.87 for the overall summary, respectively. Also, the correlation between the components of KCCQ and MLHQ showed satisfactory construct validity. Good Pearson's Correlation Coefficient was seen between KCCQ and MLHF (r= -0.44, P≤0.000 for the clinical summary; r= -0.45, P≤0.000 for the overall summary). Analysing the data from 50 healthy persons and 150 patients were shown that the Persian version of KCCQ has acceptable discriminate validity for all domains except self-efficacy. The Persian version of the KCCQ had satisfactory reliability and validity for assessing health-related quality of life status for Iranian CHF patients.

Authors: Jalalian Azin , Shafaroodi Hamed , Fereydani Mahsa
Published: June 2024

Antibiotics are medicines that fight against bacterial infections and are usually considered safe drugs. However, they can simultaneously cause several adverse reactions. Nitrofurantoin, which is mainly administered for treatment and prevention of urinary tract infections, causes seizure reportedly. Therefore, further research is required to be conducted to simulate the case report situations and examine whether nitrofurantoin is the main factor leading to seizures. To do this, NMRI male mice (20-30 gr) were chosen and classified into different groups in both acute and chronic phases. Each phase contained mice treated with nitrofurantoin, phenytoin and the combination of both drugs as well as untreated control group. An Electroshock device was used to induce seizure in mice and then the effect of nitrofurantoin and phenytoin was examined in acute and chronic phases. Seizure induction in mice was examined 30 minutes and one week after injection in acute and chronic phases, respectively. Results indicated that THE (Tonic Hind-limb Extension) duration was different among the studied groups. Nitrofurantoin-injected mice were revealed to have a higher THE duration in comparison with control group, while phenytoin-injected group showed a lower THE duration. Furthermore, administration of nitrofurantoin and phenytoin combination reduced THE duration in both acute and chronic phases. Our conclusion is that nitrofurantoin can possess convulsive effects and cause seizure as a side effect.

Published: June 2024

Background: The viability and persistence of engineered bacterium candidates in field conditions is one of the consid­erable challenges in the paratransgenesis approach to fighting vector-borne diseases.
Methods: In this study two engineered bacterium candidates to produce paratransgenic sand flies, Serratia AS1 and Enterobacter cloacae expressing m-Cherry fluorescent were applied on the leaves of the white saxaul plant (Haloxylon persicum), sugar bait, and rodent burrow soil and their persistent time was tested in desert condition, Matin Abad Coun­ty, Isfahan, August 2022. A PBS suspension of 109 cells/ml was used for sugar bait, spraying on plant leaves (~10 cm2) and 10 cm2 of rodent burrow soil. Sand fly samples were taken daily and were plated on LB Agar and the fluorescent cells were counted after 24 hours.
Results: Time course in general caused a decrease in the number of bacteria for both strains. The two strains were per­sistent in sugar bait and on plant leaves for four days and on soil for two days. Although there were slight differences between the number of the bacteria in sugar baits, which was not significant (P< 0.05). The number of E. cloacae sur­viving on plant and in soil were significantly (P< 0.0001 and P= 0.046) higher than Serratia AS1.
Conclusion: This study shows that plants or sugar bait are useful routes for delivery of the transformed bacteria for the paratransgenesis approach, although, the bacteria ought to be sprayed on plants or sugar baits should be replaced with new ones in four days intervals.

Published: June 2024

Cardiovascular diseases, a leading cause of global mortality, underscore the urgency for refined diagnostic techniques. Among these, cardiomyopathies characterized by abnormal heart wall thickening present a formidable challenge, exacerbated by aging populations and the side effects of chemotherapy. Traditional echocardiogram analysis, demanding considerable time and expertise, now faces overwhelming pressure due to escalating demands for cardiac care. This study addresses these challenges by harnessing the potential of Convolutional Neural Networks, specifically YOLOv8, U-Net, and Attention U-Net, leveraging the EchoNet-Dynamic dataset from Stanford University Hospital to segment echocardiographic images. Our investigation aimed to optimize and compare these models for segmenting the left ventricle in echocardiography images, a crucial step for quantifying key cardiac parameters. We demonstrate the superiority of U-Net and Attention U-Net over YOLOv8, with Attention U-Net achieving the highest Dice Coefficient Score due to its focus on relevant features via attention mechanisms. This finding highlights the importance of model specificity in medical image segmentation and points to attention mechanisms. The integration of AI in echocardiography represents a pivotal shift toward precision medicine, improving diagnostic accuracy and operational efficiency. Our results advocate for the continued development and application of AI-driven models, underscoring their potential to transform cardiovascular diagnostics through enhanced precision and multimodal data integration. This study validates the effectiveness of state-of-the-art AI models in cardiac function assessment and paves the way for their implementation in clinical settings, thereby contributing significantly to the advancement of cardiac healthcare delivery.

Published: June 2024

Objective: Aim of this study is to evaluate the association between subcutaneous fat thickness (SCFT) and biochemical recurrence (BCR) in patients who have undergone radical prostatectomy (RP).
Material and Methods: Study included 52 patients who had non-metastatic prostate cancer (PCa), underwent RP at our center between April 2015 and January 2020. All patients had a full abdomen computed tomography (CT) scan within six months prior to surgery. Measurements of fat, muscle, and tissue were evaluated by two radiologists, and binary logistic regression analysis was performed to determine factors influencing BCR. SCFT was identified as the only radiological factor influencing recurrence. A cut-off value (25.6) was determined using an ROC curve, and patients were divided into two groups based on this value.
Results: In Group 1 (SCFT < 25.6), the median recurrence time was 39 (3-65) months, and the median follow-up time was 40.5 (17-65) months. In Group 2 (SCFT ≥ 25.6), the median recurrence time was 20.5 (3-58) months, and the median follow-up time was 43 (12-69) months. The one-year and three-year recurrence-free survival rates were 82.1% and 78.4% for Group 1, respectively, while they were 62.5% and 52.2% for Group 2, respectively (p=0.047).
Conclusions: The ability to predict recurrence in PCa is crucial for the management and treatment of the disease. Our study, which demonstrates a significant relationship between SCFT and BCR, suggests that radiological evaluation and measurements will be further utilized in the diagnosis, treatment, and follow-up of the disease.
Multilevel Logistic Regression Analysis of Correlates of Graduate Employment by Fields of Specialization

Published: June 2024

A number of research settings involve data having a multilevel (hierarchical) structure. Failing to take into account such hierarchical structures may lead to wrong statistical inference. The objective of this study was to explore the correlates of employment status among graduates of Ethiopian Higher Education Institutions nested within their fields of specialization using hierarchical two‐level logistic regression model. The study sample consisted of 2569 graduates nested within 20 fields of specialization. The impact of level-1 covariates and fields of specialization on employment outcome was explored using average marginal effects. The estimated variance of the random (field of specialization) effects was found to be significant – an indication that a multilevel model is appropriate. Likelihood ratio test confirmed that the multilevel random coefficients model was a better fit to the data. Besides demographic and socio-economic characteristics of graduates (and their households), the dimensions related to the skills and competences of graduates, namely perceived level of training of graduates on technical/practical skills and soft skills at their universities as well as cumulative grade point average, had significant influence on employment outcomes. The results also revealed that the effect of practical skills on graduate employment varied across fields of specialization. Average marginal effects analysis indicated that the probability of employment was lower for graduates who were unmarried, aged below 25, with disability, from a low income family and those graduates who perceived that their preparation for practical as well as soft skills required in the job market was less than expected/very poor. Moreover, practical and soft skills differentials in the probability of graduate employment were found to diminish with an increase in cumulative grade point average. To improve graduate employment, provision of adequate training in practical/technical and soft skills is recommended.

The widespread use of fossil fuels for global energy production significantly contributes to global warming. This study presents a comparative analysis of various machine learning models, which are the long short-term memory (LSTM) network, support vector regression (SVR), and gradient boosting method (GBM). Gaussian process regression (GPR) is a benchmark model across different forecasting horizons. The study uses South African wind speed data from 1 January 2018 to 31 December 2021, sourced from the Western Cape province. The dataset underwent preprocessing, and diverse feature selection techniques were implemented to enhance model accuracy. Performance evaluation of the models was done using mean absolute error (MAE), root mean squared error (RMSE), and mean absolute scaled error (MASE). Results indicate that SVR exhibits superior accuracy to other models for two distinct forecast horizons (h = 670 and h = 1339), respectively. Additionally, GPR surpasses other models for the forecasting horizon h = 224. This study provides insights into the comparative strengths and weaknesses of different machine learning models for wind speed prediction, which could be useful in selecting an appropriate model for future applications in renewable energy and weather forecasting. Potential areas for future research include improving prediction accuracy via ensemble deep learning algorithms and incorporating additional meteorological variables. Moreover, investigating temporal dynamics, broadening geographical coverage and integrating uncertainty quantification methods can improve wind speed prediction, thereby facilitating more effective renewable energy planning and decision-making processes
Reading for the Technical Workplace

Published: June 2024

Proficient communication, particularly reading comprehension, is vital for career progression, yet many college-level English as an Additional Language (EAL) students encounter hurdles in this area. Weak reading skills can impede job prospects, underscoring the need for tailored interventions during students’ studies. Therefore, post-entry language assessments (PELAs) can serve as essential tools for post-secondary institutions, aiding in identifying and supporting students struggling with English proficiency. PELAs adopt a diagnostic approach, facilitating language development while maintaining educational experiences. Despite increased interest in PELAs, few diagnostic assessments cater specifically to reading proficiency. This paper explores the creation of a PELA for first-year college students in Canada, designed to prepare them for diverse workplaces. Utilizing Evidence-Centered Design (ECD) ensures validity in assessment development, emphasizing inference-based reasoning from individuals’ responses. Insights from a task survey with 12 professionals underscored the significance of understanding instructional texts for academic and professional success, informing the development of a diagnostic reading assessment beneficial to both multilingual and L1 literacy students.
Une communication efficace, en particulier sur le plan de la compréhension écrite, est vitale pour l’avancement professionnel. Cependant, de nombreux étudiants de l’anglais comme langue additionnelle (ELA) au niveau universitaire rencontrent des obstacles sur ce niveau. De faibles compétences en lecture peuvent entraver les perspectives d’emploi, ce qui souligne la nécessité d’interventions personnalisées pendant les études. Par conséquent, les évaluations linguistiques à l’entrée (ÉLE) peuvent constituer des outils essentiels pour les établissements d’enseignement postsecondaires, en aidant à identifier et à soutenir les étudiants qui éprouvent des difficultés en anglais. Les ÉLE adoptent une approche diagnostique, facilitant le développement de la langue tout en maintenant le vécu éducatif. Malgré l’intérêt croissant pour les ÉLE, peu d’évaluations diagnostiques portent spécifiquement sur la compétence de compréhension écrite. Cet article explore la création d’une ÉLE pour des étudiants de première année universitaire au Canada, conçue pour les préparer à des lieux de travail diversifiés. L’utilisation de la conception centrée sur les preuves (CCP) garantit la validité dans le développement de l’évaluation, en mettant l’accent sur le raisonnement basé sur l’inférence à partir des réponses des individus. Les résultats d’un sondage sur les tâches mené auprès de 12 professionnels mettent en lumière l’importance de la compréhension des textes pédagogiques pour la réussite scolaire et professionnelle, ce qui a permis d’élaborer une évaluation diagnostique de la lecture qui peut être utilisée avec des étudiants en apprentissage de la littératie en langue première et dans des langues additionnelles.
Breaking More than the Ice

Published: June 2024

Plurilingualism has populated the intersection of theory and pedagogy with practices that support the inclusion of diverse linguistic and cultural identities in language education. In some educational contexts, such as English for Academic Purposes (EAP), plurilingual practices can be met with resistance due to systemic target-language-only beliefs and approaches. This article aims to resist monolingualism in EAP by detailing the benefits of incorporating identity-based icebreaker activities within a plurilingual framework. Using an action research methodology, this article draws on class recordings, lesson plans, and observation notes to analyze the implementation of a series of identity-based icebreakers in an online EAP course at a Canadian university. Findings show that the systematic use of identity-based icebreakers afforded affirmations of plurilingual identities in class, while coinciding with the emergence of vulnerability, community, and criticality. This article contributes to contextualized understandings of the use of plurilingual pedagogical strategies in a traditionally monolingual teaching context, suggesting that even micro activities can have an impact on linguistic and cultural inclusion in language education.
Le plurilinguisme se situe à l’intersection de la théorie et de la pédagogie avec des pratiques qui soutiennent l’inclusion de diverses identités linguistiques et culturelles dans l’enseignement des langues. Dans certains contextes éducatifs, tels que l’anglais sur objectifs académiques (AOA), les pratiques plurilingues peuvent se heurter à une certaine résistance en raison de croyances et d’approches systémiques axées sur l’utilisation exclusive de la langue cible. Cet article vise à résister au monolinguisme dans le contexte de l’AOA en détaillant les avantages de l’intégration d’activités brise-glace basées sur l’identité dans un cadre plurilingue. En utilisant une méthodologie de recherche-action, cet article s’appuie sur des enregistrements de classe, des plans de cours et des notes d’observation pour analyser la mise en oeuvre d’une série d’activités briseglace basées sur l’identité dans un cours d’AOA en ligne dans une université canadienne. Les résultats montrent que l’utilisation systématique de brise-glace basés sur l’identité a permis d’affirmer les identités plurilingues en classe, tout en coïncidant avec l’émergence de la vulnérabilité, de l’esprit de communauté et de l’esprit critique. Cet article contribue à la compréhension contextualisée de l’utilisation de stratégies pédagogiques plurilingues dans un contexte d’enseignement traditionnellement monolingue et suggère que même de courtes activités peuvent avoir un impact sur l’inclusion linguistique et culturelle dans l’enseignement des langues.
II. Abdülhamid Döneminde Macarların İstanbul Ziyaretleri
Authors: Çiftçioğlu Ferdi
Published: June 2024

İstanbul, tarih boyunca pek çok medeniyetin izlerini taşıyan, stratejik konum ve zengin kültürel mirasa sahip önemli bir şehirdir. Büyük medeniyetlere başkentlik yapmış, ticaret yollarının kesişim noktası olmuş ve farklı kültürlerin birleşim noktası haline gelmiştir. Bu özellikleri ile birçok seyyahın uğrak noktası olmuştur. İstanbul’a gelen seyyahlar-ziyaretçiler şehrin benzersiz atmosferini ve zenginliklerini keşfetmek istemişlerdir. Bunun yanı sıra şehir, tarih boyunca önemli devlet adamlarının, yazarların, sanatçıların ve bilginlerin de ilgisini çekmeye başlamıştır. Bu ilgi, Macarların bireysel olarak veya kafileler halinde İstanbul’a seyahatler düzenlemesini beraberinde getirmiştir. XIX. yüzyılın sonlarında Macarların gelenekselleşen İstanbul ziyaretleri bu söylemin bir tezahürüdür. Bu ziyaretler genellikle turistik bir geziden ziyade devlet ricalinin özel karşılamaları ve ziyaretçilere eşlik etmeleri ile farklı bir boyut kazanmıştır. Ayrıca Osmanlı Devleti’nin Macaristan ile gelişen ilişkileri itibariyle Macar ziyaretçiler ve seyyahlar diğer ülke ziyaretçilerinden daha ayrıcalıklı bir konumda tutulmuşlardır. Bu sayede, İstanbul’un tarihini ve kültürel dokusunu en ince detayına kadar keşfetme fırsatını yakalamışlardır. Osmanlı Devleti’nin önemli makamlarını ziyaret ederek ve şehrin her köşesini gezip görerek kendilerine özgü bir İstanbul deneyimi yaşamışlardır. Yüzyılın sonuna doğru Macarların İstanbul’a olan ilgileri kafileler halinde gerçekleştirdikleri ziyaret ve seyahatlerle kendini göstermiştir. Gezileri sırasındaki tecrübe ve izlenimlerini dönemin Macar basınına aktarmaktan da geri kalmamışlardır. Macar basınına yansıyan izlenimlere, Türklere ve İstanbul’a dair düşünceler de eklenince iki millet arasındaki samimiyet daha ileri seviyelere ulaşmıştır. Bunun yanında seyyahların yazıları, İstanbul’un siyasi, sosyal ve kültürel hayatına dair farklı bakış açıları sunmuştur. Bu çalışmada II. Abdülhamid devrinde Macarların İstanbul’a yaptığı ziyaretler ele alınmıştır.
Naki Tezel’in “Yıkılan Köprü” Adlı Eserine Millî Mücadelenin Yansımaları
Authors: Öksüz Güneş Elif
Published: June 2024

Millî Mücadele, çok uluslu yapıya sahip olan Osmanlı Devleti’nin İtilaf Devletleri tarafından toprak bütünlüğünün tehdidi sırasında hem dış güçlerle hem de vatanı işgal edenlere yakınlık duyarak önemli mevkilerde görev yapma yanılgısına düşenlerle mücadele ettiği sürecin adıdır. Bu süreçte “öteki” ile iş birliği yaparak işgallere karşı askerî ve siyasî alanda pasif tavırlarıyla Türk’ün bağımsızlık savaşına zarar veren yozlaşmış kişilerin bilinçsizlik hali, Batı Anadolu’ya medeniyet ve erinç getirecekleri iddiasındaki düşmanın eylemlerini meşru göstermelerini kolaylaştırır. Bu durum resmî tarihin kayıtlarına geçtiği gibi millî yaşamın düşünsel ve duygusal değerlerinin yansıtıcısı işlevini gören edebî metinlere de yansır. Naki Tezel, önemli folklor araştırmacılarındandır. Sanatkâr, tek hikâye kitabı olan Yıkılan Köprü adlı eserinde Türk’ün erkini koruma amacıyla verdiği savaşta millî bilince sahip olanları ve bu bilince sahip olmayanları kurgusal düzleme taşır. Bu çalışmada Osmanlı Devleti’nin dağılma, millî bir devletin kurulma aşamasındaki sancılı sürecin Yıkılan Köprü’deki görünümleri “kendi olma”, “yozlaşma” ve “Millî bilinçten uzaklaşma/ötekileşme” temaları bağlamında değerlendirilecektir.

Authors: Yenice Güler
Published: June 2024

Meat is the most crucial protein source for human nutrition. Poultry meat production and consumption ranks first in the world ranking. However, in parallel with population growth, demand and production costs increase continuously. One of the main feed ingredients in chicken diets, protein sources constitute a significant part of the cost. Therefore, the look for cheaper and alternative sources to reduce feed costs is a current issue. In recent years, the number of studies using various insects including black soldier fly larvae, crickets, or mealworms as an alternative protein source has increased. In this review, the effects of using insects as an alternative protein source on broiler meat quality are discussed.
Monetary and Fiscal Policy Interactions and the Impact of the COVID-19 Pandemic
Authors: Burdekin Richard , Horan John , Tao Ran
Published: June 2024

Although the onset of the pandemic pressured monetary and fiscal policy across the globe, deficit finance was aided by the large, established debt markets in countries like the United States.  The expansionary efforts in emerging markets like Latin America put greater strains on their more limited capacity.  Our study analyzes data from seven Latin American countries, three European countries, three Asian countries, and the United States. We utilize panel vector autoregressive (VAR) models to explore the dynamic interactions and feedback mechanisms among the policy variables, while accounting for unobserved country-specific effects.  Our results demonstrate strong and significant interactions between monetary and fiscal policy around the time of the pandemic, with the primary causal effects running from fiscal to monetary policy.  Additionally, our results yield evidence of countercyclical policy reactions to inflation for both monetary and fiscal policy over the pandemic period.
