A Quadratic Curve Analogue of the Taniyama-Shimura Conjecture
Authors: Hayashi Masahito , Shigemoto Kazuyasu , Tsukioka Takuya
Published: November 2024

For quadratic curves over finite fileds, the number of solutions, which is governed by an analogue of the Mordell-Weil group, is expressed with the Legendre symbol of a coefficient of quadratic curves. Focusing on the number of solutions, a quadratic curve analogue of the modular form in the Taniyama-Shimura conjecture is proposed. This modular form yields the Gaussian sum and also possesses some modular transformation structure.

Published: November 2024

Introduction: Cardiac point of care ultrasound (POCUS) has been used with increasing frequency. As a result of this trend, this study sought to characterize cardiologists’ perspectives on cardiac POCUS. Methods: An 18-question survey on demographics, cardiac POCUS clinical practice, education, and infrastructure was distributed by 16 academic medical centers. Likert scale responses were categorized into three groups: 1) “strongly agree” or “agree” 2) “strongly disagree” and “disagree” and 3) “neutral.” Results: Of the 140 survey responses collected from January to September 2021, 41% of respondents used cardiac POCUS more than twice in an inpatient week. Seventy-one percent of cardiologists believed that cardiac POCUS should be integrated more regularly into clinical practice and into cardiology fellowship education. Less than half of respondents (44%) reported easy access to POCUS devices, and more than half of respondents (56%) did not think there was appropriate institutional infrastructure to easily upload and document cardiac POCUS images (56%). Conclusions: Academic cardiologists had varying opinions on the use and impact of cardiac POCUS. However, most cardiologists believed that cardiac POCUS should be more incorporated within practice despite persisting infrastructure barriers.

Published: November 2024

Aim: To analyze the association between pleural effusion detected by chest point of care ultrasound (POCUS) and clinical outcomes in patients with septic shock admitted to an intensive care unit (ICU). Material and methods: A prospective evaluation of ICU patients with septic shock in whom chest POCUS was performed during the first 24 hours of diagnosis to identify the presence and characteristics of pleural effusion. Results: Of 45 patients with septic shock, 17 (38%) had pleural effusion. Mortality (13 vs 17 patients, p=0.44), as well as length of stay in ICU (11.0 vs 6.5 days, p=0.161) were similar among groups. However, there was a significant difference in the modified Nutrition Risk in Critically Ill (mNUTRIC) score between the pleural effusion (5.82±1.13) and non-pleural effusion groups (4.00±2.39, p=0.001). In addition, patients with pleural effusion required more days on mechanical ventilation than those without pleural effusion (10 vs 7, p=0.04). A subgroup analysis of chest POCUS characteristics between surviving and non-surviving patients with pleural effusion identified a higher median size of pleural effusion in the non-surviving group (3±2.16 cm vs 1.9±0.6, p=0.01). Conclusion: Pleural effusion in patients with septic shock is associated with high mNUTRIC scores and more days on mechanical ventilation. The larger the pleural effusion, the lower the survival rate.
Diagnosis of a Stress Fracture Of a Metatarsal Bone with Point of Care Ultrasound (POCUS)
Authors: Doblinger Alfred
Published: November 2024

The early diagnosis of stress fractures is a challenge in daily primary care practice. Point of care ultrasound (POCUS) can be helpful in the diagnosis of early signs of an incipient stress fracture. A 52-year-old woman presented with a history of chronic overuse in the left forefoot. A sonographic examination in the area of the reported pain point on the third metatarsal (consistent with a marching fracture) showed a clear accumulation of fluid, corresponding to subperiosteal hematoma. After only two weeks of resting the forefoot, a repeat examination using POCUS showed clear callus formation. This confirmed the suspected diagnosis of an early stage stress fracture. This case shows a sensible and easy-to-learn way of using POCUS in general practice. POCUS in combination with clinical examination and anamnesis is a cost-effective and timely diagnostic option without radiation exposure.

Acalculous cholecystitis is a life-threatening diagnosis that is more commonly associated with ill patients in the ICU. We present a case of acute acalculous cholecystitis (ACC) in an otherwise healthy 18-year-old man who presented to the Emergency Department (ED) with right-sided chest pain that was ultimately diagnosed with point of care ultrasound (POCUS). This case demonstrates the importance of conducting a thorough history and physical as well as the importance of POCUS to aid in clinical decision making and its value in diagnosing acute biliary pathology in the ED.
Lung Point in a Case of Bronchoscopy Lung Volume Reduction: Consider Its Mimics Before Inserting the Tube
Authors: Wazirali Mohannad , Shaniuk Paul M
Published: November 2024

Point of Care Ultrasound (POCUS) is used to evaluate many clinical scenarios. Chest POCUS has been integrated as a part of a clinical protocol to assess patients with lung pathology [1]. The ability to detect pneumothorax using chest POCUS has been shown to be superior to chest radiography, with specificity reported to be as high as 100% when a lung point sign is identified. In addition to improved diagnostic accuracy, chest POCUS has the added benefits of ease of access and absence of ionizing radiation. Here we describe a case where a patient with a high pre-test probability for pneumothorax had a detected lung point sign, but pneumothorax was ruled out via Computed Tomography (CT). This case highlights the importance of considering the mimics of the lung point sign. This case also shows a unique and interesting finding related to pleural movement restriction post-Bronchoscopic lung volume reduction (BLVR).

Authors: Ching Alisha , Kropf Charles William
Published: November 2024

Application of ultrasound to evaluate pediatric respiratory disease in the emergency department setting is rapidly growing, particularly as we often weigh the risks of exposure to radiation with other readily available imaging modalities in the acute care setting. In this case report, we describe how point of care ultrasound (POCUS) was utilized by emergency providers to characterize a lung abscess diagnosed in a pediatric patient. We also compare the ultrasound findings to other imaging studies.
A Rare Case of Hemoperitoneum Diagnosed with Point of Care Ultrasound (POCUS)
Authors: Bai Jina , Cutler Todd
Published: November 2024

A 68-year-old man presented with one week of vague abdominal symptoms and was found to have new ascites and pulmonary embolism for which a heparin drip was initiated. We report a case diagnosing hemoperitoneum with point of care ultrasound (POCUS). Identifying hemoperitoneum can be challenging, but POCUS can be a useful tool for its diagnosis. There is limited literature on the sonographic characteristics of hemoperitoneum. Echogenicity of fluid is not a reliable distinguisher between exudative and transudative effusions. The diagnosis of hemoperitoneum in this case was suggested by the progression of POCUS findings over time rather than sonographic characteristics by themselves.
Just In Time! Assessment of Internal Medicine Resident Point of Care Ultrasound (POCUS) Attitudes and Behaviors After Spaced Intervention at Two Residency Programs
Authors: Piro Kevin , Carney Patricia , Smith Christopher
Published: November 2024

Point of care ultrasound (POCUS) is a complex psychomotor skill that requires scaffolded support for skill acquisition. However, the effect of spaced curricular elements on learner POCUS behaviors are not clearly understood. Using a multi-site observational cross-sectional survey study, we measured resident baseline POCUS use, behaviors, and attitudes and then implemented POCUS workflow and just-in-time POCUS curricula during internal medicine resident ward rotations and assessed changes. Self-reported personal and team POCUS use and documentation habits all improved between baseline and the just-in-time teaching. Personal POCUS use correlated with team POCUS use (ρ=0.431; p<0.001) and co-resident POCUS use (ρ=0.242; p=0.035). Attending POCUS use correlated with team POCUS use (ρ=0.523; p< 0.001), but not personal use. Overall, we found moderate, but statistically significant, improvements in reported resident and team performance of POCUS and documentation habits, suggesting that just-in-time interventions may promote POCUS use. Co-learning also appears to be a key influencer for POCUS use.

Authors: Ganbat Uyanga , Feldman Boris , Arishenkoff Shane , Meneilly Graydon , Madden Kenneth
Published: November 2024

Background: Gait parameters and sarcopenia both predict falls risk among older adults. Our objective was to evaluate whether fast, easy-to-obtain measures of anterior thigh muscle by point of care ultrasound (POCUS) are significantly associated with standard gait measures. Methods: All subjects were referred from ambulatory geriatric medicine clinics at an academic center. Quadriceps muscle thickness was measured by a portable ultrasound device. Gait variables were measured by the patient in comfortable walking shoes walking for six minutes. The primary response variables were gait variables, and the predictor variables were age, biological sex, body mass index, and muscle thickness. Univariate and multivariate regression analyses were performed. Results: A total of 150 participants were recruited from geriatric medicine clinics (65 women, 84 men). Muscle thickness was measured in 149 participants, and the mean (SD) was 1.91 (0.52) (median 1.82 cm, 0.96 to 3.68 cm). Univariate analysis of gait parameters with age showed a statistically significant correlation with gait speed (R2=0.16, P < 0.000), average stride length (R2=0.142, P < 0.000), and average stride velocity (R2=0.182, P < 0.000). Among all the gait variables, average swing time (P = 0.010) and average stance time (P = 0.010) were correlated significantly with muscle thickness. For multivariate analysis with age and gait variables, age was a significant independent variable for all gait variables that were significant in univariate analysis. Conclusion: POCUS showed a significant association with average swing time, average stance time, and step time variability. Although more work needs to be done, POCUS has the potential to be a rapid screening tool for gait assessment.
A Cardiac Tumor and Liver Masses on Point of Care Ultrasound (POCUS): Implications in a Resource-Limited Setting
Authors: Sous Waseem , Limwado George , Ndarama Enoch , Sous Michaela
Published: November 2024

Malignant cardiac tumors are quite rare, but portend a poor prognosis [1,2]. Early identification and classification are essential given their aggressive nature, particularly when metastases are present [3,4]. Clinical presentations are varied, and detection relies primarily on echocardiography. Thus, cardiac tumors may go undiagnosed in areas where echocardiography is not routinely available [1,5]. In this case, point of care ultrasound (POCUS) rapidly detected a cardiac mass and liver lesions, prompting referral to a central hospital in Malawi for further evaluation. This case highlighted the potential role of POCUS as a readily available tool in a resource-limited setting, serving as a triage point for more definitive diagnosis and management [6-8].
Visualizing the Real Time Reduction of Pulled Elbow Using Point of Care Ultrasound (POCUS)
Authors: McCreary David
Published: November 2024

POCUS is a useful tool for correctly identifying pulled elbow. We believe that clinicians working in Pediatric Emergency Departments should be encouraged to embrace using it in cases which are less straightforward – either due to an atypical history or based on examination findings. This will serve to not only increase safety and improve the patient journey, but also to improve the clinician’s confidence in their practice. This is the first ever documented instance where the reduction of pulled elbow has been demonstrated in real time using POCUS.

Published: November 2024

Dear Readers,
We are thrilled to bring you the second issue of the ninth volume of POCUS Journal. Published since 2016, POCUS Journal is the only multi-disciplinary, peer-reviewed, POCUS-focused journal that is free for authors and readers alike.
This issue features a variety of POCUS articles from around the world: from North America, South America, Europe, Asia, and even Australia. In addition to novel cases with striking POCUS images and video clips, this issue boasts a great deal of educational research at all levels: Danila et al. (page 80) report on their study of how POCUS can augment a medical student preclinical cardiovascular course while Piro et al. (page 93) studied the impact of just-in-time POCUS curriculum on internal medicine residents; Janjigian et al. (page 109) studied the longitudinal impact of a faculty POCUS training course. POCUS is a powerful tool with a wide range of applications: for example, it can be used both to diagnose musculoskeletal conditions (Doblinger et al. page 15 and Mack et al. page 27) and to treat musculoskeletal conditions (Bowling et al page 12, and McCreary et al. page 30). POCUS can also be used to predict heart failure readmission (Malagón et al. page 125). We are so excited to showcase pivotal POCUS scholarship like this in the November issue.
I hope you enjoy this issue of POCUS Journal as much as I have. A huge thank you to our authors, editorial board, and publisher.

Single-center experience of four cases with iron-refractory iron deficiency anemia (IRIDA)
Authors: Parlak Gülin , Aksu Muhammed Doğukan , Gümrük Fatma , Ünal Şule
Published: November 2024

Background. Iron refractory iron deficiency anemia (IRIDA) is a rare autosomal recessive type of anemia characterized by unresponsiveness to oral iron therapy and partial response to parenteral iron therapy. In this article, we report the clinical presentation of four patients with IRIDA admitted to our clinic, including their laboratory values at admission and after oral and parenteral iron treatment, and the analysis of their mutation(s) in TMPRSS6 gene.
Case. Four patients from different families, aged between 3 and 14 years, two girls and two boys, two of whom were from consanguineous marriages, who were diagnosed with iron deficiency anemia in primary health care institutions and referred to our clinic because of inadequate response to oral iron treatment were included. Patients were evaluated for the differential diagnosis of microcytic, hypochromic anemia and investigated for the etiology of IDA. Homozygous or compound heterozygous mutations causing defective matriptase-2 protein expression were detected in the TMPRSS6 gene; these mutations included four frameshift mutations-two of which were the same in two cases and causing premature terminal stop codons-and a nonsense mutation, all of which were previously demonstrated in the literature. The response to parental iron therapy ranged from complete non-response to mild to good response in hemoglobin levels, but none of the patients showed improvement in iron parameters.
Conclusions. Increased awareness of IRIDA and keeping it in mind in the differential diagnosis in the presence of hypochromic microcytic anemia that does not respond to iron treatment will be crucial in improving the diagnosis and treatment of the disease and ultimately enhancing the quality of care for affected individuals.

Published: November 2024

The proposed framework can capture realistic spatiotemporal variations in atmospheric turbulence parameters based on local meteorological conditions, such as Fried's parameter r0, isoplanatic angles θ0, seeing ε, scintillation rate , and the wavefront coherence time τ0. Those parameters have been deduced from the refractive index structure parameter Two Iraqi locations were compared, specifically the middle and southern borders, and atmospheric turbulence parameters relevant to astronomical observation were measured, lines were drawn at latitudes 34.26° and 28.31°, respectively. The methodology included collecting meteorological data from both sites and performing numerical simulations based on atmospheric turbulence parameters. According to the criteria of air turbulence, the results showed that the middle of Iraq was better than the southern location for astronomical observation.
Investigating the Annual Cross-Correlation between HPF, OWF and BUF Ionospheric Parameters over Middle East Region
Authors: Ezzat Aula A. , Hadi Khalid A.
Published: November 2024

In this work various correlation methods were employed to investigate the annual cross-correlation patterns among three different ionospheric parameters: Optimum Working Frequency (OWF), Highest Probable Frequency (HPF), and Best Usable Frequency (BUF). The annual predicted dataset for these parameters were generated using VOCAP and ASASPS models based on the monthly Sunspot Numbers (SSN) during two years of solar cycle 24, minimum 2009 and maximum 2014. The investigation was conducted for Thirty-two different transmitter/receiver stations distributed over Middle East. The locations were selected based on the geodesic parameters which were calculated for different path lengths (500, 1000, 1500, and 2000) km and bearings (N, NE, E, SE, S, SW, W, NW) using a Matlab program that was designed and implemented for this purpose. Depending on the investigation results of the cross-correlation, a third order polynomial equation provides a better representation of the correlation between the tested parameters. Also, the annual values of the HPF, OWF, and BUF parameters were predicted using the proposed mathematical correlation equations. These equations were confirmed by comparing their results with the observed datasets for the studied years. Several statistical methods were used to validate the presented data, all of which gave good results for all tested cases. Also, contour plot diagrams were used to visually illustrate the annual average distribution pattern of the tested ionospheric parameters for all geodetic factors for the minimum and maximum years of Solar Cycle 24.
Direction of Arrival Estimation of Meteors Echoes using Array Radio Antennas
Authors: Akeab Imad K. , Bekheet Yasser Chasib , Al Najm M. N.
Published: November 2024

Array antennas have an interesting role in the radio astronomy field. The array antennas allow astronomers to obtain high-resolution signals with high sensitivity to weak signals. This paper estimates the meteors' positions entering the Earth's atmosphere and develops a simulation for array antenna radar to analyze the meteor's echoes. The GNU radio software was used to process the echoes, which is a free open-source software development toolkit that provides signal processing blocks to implement in radio projects. Then, the simulation determines the azimuth and elevation of the meteors. An improved Multiple Signal Classification (MUSIC) algorithm has been suggested to analyze these echoes. The detected power of each meteor echo has a Doppler frequency shift due to the high speed of the meteors, which impacts the accuracy of the Direction of Arrival (DOA) estimation. The Doppler shift was considered in this simulation, and the results showed that the suggested method has low complexity and high resolution and can estimate the meteors' position with the minimum error.

Published: November 2024

Understanding the motion of celestial objects is essential for space exploration. Observing the new crescent Moon requires advanced technological devices due to the moon’s position in the atmosphere and the refraction of sunlight on the horizon. Nowadays, theodolite and telescope applications are commonly used for new crescent moon sightings because they offer superior visibility compared to the naked eye. In Sarawak, the Falak Section holds the authority to observe the new crescent Moon to determine the beginning of the Hijree month. Thus, this study aims to examine the development of devices to observe the new moon crescent in the Sarawak Mufti Department. Qualitative methods are employed, involving the perspectives of astronomers and data on new crescent Moon observations using the observation devices in the Falak Section. From 1997 onwards, the Sarawak Mufti Department had three theodolites and seven telescopes specifically for new crescent moon observations. Additionally, there are 22 recorded data of new crescent Moon sightings using these devices. These findings indicate a direct correlation between the observation devices and the potential visibility of the new crescent Moon in Sarawak. This study will benefit the Sarawak Mufti Department in evaluating suitable devices for new crescent Moon observations, whether acquiring new devices or selecting devices for new crescent moon observations.

Authors: Hanash Ruaa Faraj , Khalaf Salman Zaidan
Published: November 2024

This paper gives a dynamic analysis of the recently identified calibration parameter (NRSK) in the distance modulus equation for all celestial planets. The parameter NRSK has been applied for seven different comets from the Kuiper-Belt region: (1P/Hally, C/2023 E1 (ATLAS), 23P/Brorsen-Metcalf, 20D/Westphal, 12P/Pons-Brooks, 13P/Olbers, and C/2022 P1 (NEOWISE)). This was accomplished by programming data from the Live Sky program from previous years. It is determined that each comet has a distinctive NRSK that distinguishes it from other comets and that this parameter does not equal one. According to the data, the seven comets' average NRSK is (2.53 for 1P/Hally, 2.561forC/2023 E1 (ATLAS), 2.57 for 23P/Brorsen-Metcalf, 3.07 for 20D/Westphal, 4.11 for 12P/Pons-Brooks, 4.12 for 13P/Olbers, and 3.07 for C/2022 P1 (NEOWISE).

Selecting Suitable Sites for Wind Energy Harvesting in Iraq using GIS Techniques
Authors: Nassif Wedyan G. , Elhmaidi Dalila , Al-Timimi Yaseen K.
Published: November 2024

Wind energy harnesses the kinetic force of the wind through turbines to produce electricity. As a critical renewable energy source, it presents a sustainable alternative to fossil fuels. The availability of wind energy is geographically contingent. This paper aims to pinpoint optimal sites for wind energy development in Iraq and to secure future energy needs from renewable sources to achieve this, a multi-criteria analysis utilizing Geographic Information Systems (GIS) was employed to determine the prime locations for wind energy extraction. Vital climatic data incorporated into this analysis included a RASTER file of the study area's annual wind speed, temperature, precipitation, soil moisture, and NDVI (Normalized Difference Vegetation Index) roads, urban centers, terrain gradients, and land utilization patterns were instrumental in constructing a GIS-based model. This model harnessed the weighted overlay tool within ArcGIS 10.7.1's Spatial Analysis Tools to classify and integrate various raster datasets. Findings reveal that the most favorable locations for wind energy exploitation are in Iraq's southeastern sectors. These zones are not only marked by vigorous winds averaging speeds over 6.2 meters per second but also benefit from their proximity to power grids, accessible roads, and gentle slopes, making them prime candidates for wind farm installation. The research also notes that regions with a high suitability index for wind energy development constitute 5.3% of the total examined area. This is a robust indicator of Iraq's capacity for wind energy utilization. Meanwhile, 79.7% of the territory received a moderate suitability rating, 9.5% was categorized as poorly suitable, and 5.4% was considered unsuitable for wind energy projects. These insights underscore the significant potential for harvesting wind energy in Iraq and guide strategic planning for its implementation.

Authors: Mousa Ola T. , Hadi Khalid A.
Published: November 2024

The present work aimed to make a comparative investigation between three different ionospheric models: IRI-2020, ASAPS and VOACAP. The purpose of the comparative study is to investigate the compatibility of predicting the Maximum Usable Frequency parameter (MUF) over mid-latitude region during the severe geomagnetic storm on 17 March 2015. Three stations distributed in the mid-latitudes were selected for study; these are (Athens (23.50o E, 38.00o N), Jeju (124.53o E, 33.6o N) and Pt. Arguello (239.50o W, 34.80o N). The daily MUF outcomes were calculated using the tested models for the three adopted sites, for a span of five-day (the day of the event and two days preceding and following the event day). The calculated datasets were compared for each location with the observed daily MUF values. In general, the findings show that the three investigated models gave good outcomes compared to the observed values for all selected stations. The comparative investigation results of the three tested models corresponding to the observed MUF values during the storm event revealed that the IRI -2020 Model indicate a clear impact of the geomagnetic storm on the predicted MUF values during the day of event. Similarly, for ASAPS Model, the storm's impact is clear on both the day of the event and the subsequent day, in contrast, the VOACAP model showed almost no impact of the geomagnetic storm on the observed MUF values throughout the entire study period for event 17 March 2015.
The Impact of Geomagnetic Storms on the Ionospheric Critical Frequency in the Northern and Southern Mid-Latitude Hemisphere Regions
Authors: Breber Salma H. , Hadi Khalid A.
Published: November 2024

In this work, the impact of different geomagnetic storm events on the plasma-sphere layer (ionosphere layer) over the northern and southern hemisphere regions was investigated during solar cycle 23. To grasp the influence of geomagnetic storms on the behavior and variation of the critical frequency parameter of the F2 ionospheric layer (foF2), five geomagnetic storms (classified as great, severe, and strong), with Disturbance storm time (Dst) values <-100 nT were chosen. Four stations located in different mid-latitude regions in northern and southern hemispheres were designated, the northern stations are: Millstone Hill (42.6° N, 288.50° W) and Rome (41.90° N, 12.50° E) and the southern stations are: Port Stanley (-51.60° S, 302.10° W) and Grahamstown (-33.30° S, 26.50° E). The findings of this study showed that during events of 16 July 2000 and 24 August 2005, the negative storms cause a noticeable reduction in the values of the foF2 parameter at the northern hemisphere stations compared to those at the southern hemisphere. These outcomes are consistent with the results of the examining the variation of D(foF2) and the electron density depletion during the tested event times at all stations except in Rome, where minor enhancements in foF2 value were observed during the August 24 2005 storm. During equinox storm events occurring on March 31 and November 6 2001, a noticeable negative impact of storms was observed across all stations. However, at Millstone Hill and Port Stanley stations, the results showed a slight positive storm impact during the October 21, 2001event.

Data collection and data preprocessing are crucial stages in web usage mining, mainly because of the unstructured, diverse, and noisy nature of log data. During data collection, log file datasets are loaded and merged. Effective and comprehensive data preprocessing plays a vital role in ensuring the efficiency and scalability of algorithms used in the pattern discovery phase of web usage mining. This work aims to address these phases by introducing two innovative approaches. The first approach focuses on determining the device used for accessing the web, distinguishing between computers and mobile devices. The second approach aims to determine user sessions and complete paths by utilizing the referrer URL. The entire preprocessing pipeline has been implemented using the C# programming language, and the source code is available on GitHub at the following link: https://github.com/Mohammed91/Web-Usage-Mining.

Yapay zekâ teknolojilerinin örgütler ve örgütlü yaşam üzerindeki etkisi, iş dünyasının ve akademik çalışmaların ana meselelerinden biri haline gelmiştir. Yapay zekânın örgüt çalışmalarında giderek daha fazla yer bulduğu ve özellikle veri analizi, karar verme süreçleri ve insan kaynakları yönetimi alanlarında örgütlerin performansını artırma potansiyeline sahip olduğu görülmektedir. Bu bağlamda, çalışmada, yapay zekâ ve örgüt temelli araştırmaların mevcut ve potansiyel eğilimlerini tespit etmek, yapay zekâ ve örgüt çalışmaları arasındaki kesişim noktalarını ve araştırılmayı bekleyen alanları keşfetmek hedeflenmiştir. Yapay zekâ ve örgüt araştırmalarını konu eden çalışmaların yayın ve atıf trendleri, anahtar kavramlar ve etkileşimler üzerinden bibliyometrik bir analiz yapılmıştır. RStudio tabanlı Biblioshiny programı kullanılarak yapılan bibliyometrik analiz, Web of Science veri tabanından alınan 1085 makale üzerinden gerçekleştirilmiştir. Yapay zekâ teknolojilerinin örgütsel alanda kullanımıyla ilgili yayınların ve atıfların arttığı, bu teknolojilerin iş süreçlerine entegrasyonunun stratejik yenilikleri destekleyebileceği görüşü yayınlarda öne çıkmaktadır. Ayrıca, yapay zekâ uygulamalarının etik ve şeffaf bir şekilde yönetilmesi gerekliliği vurgulanmaktadır. Çalışma, yapay zekâ ve örgüt çalışmalarının kesişimindeki mevcut literatüre sistematik bir bakış sunarak, bu alandaki akademik tartışmalara mütevazi bir katkı sağlamakta ve gelecekteki araştırmalar için bir referans kaynağı olarak kullanılabilecek öneriler sunmaktadır.
The Role of Institutional Quality on FDI: A Comparison for Pre and Post – Global Financial Crises

Published: November 2024

In this study, the relative importance of institutional quality indicators on foreign direct investment (FDI) is investigated using a dynamic panel regression model for the countries that attracted the most FDI between 1996-2021. The World Bank (2023) data shows that FDI inflows gained a significant momentum at the beginning of the 2000s and reached its highest level in 2007. However, the Global Financial Crises (GFC) created a turning point in FDI inflows and it followed a very volatile course in the following years. For this reason, the analysis focused on the periods pre and post the global financial crisis. As a result of the study, it is revealed that all institutional quality indicators (except the rule of law) have positive effects on FDI inflows in the pre-crisis period, and regulatory effectiveness, government effectiveness and corruption control have a relatively higher impact on FDI inflows. On the other hand, it has been determined that no institutional quality indicator has a significant effect on foreign direct investments in the post-crisis period when FDI inflows are highly volatile.
Sosyal Devlet Anlayışının Bir Yansıması Olarak Sosyal Harcamalar ve Ekonomik Büyüme Üzerine Etkisi: Türkiye Üzerine Ampirik Bir Çalışma

Published: November 2024

Bu çalışma, Türkiye'de sosyal harcamaların ekonomik büyüme üzerindeki etkilerini analiz etmektedir. Sosyal devlet anlayışı, sosyal adaleti sağlama ve toplumsal refahı artırma hedefleriyle 1929 Büyük Buhran ve sonrası dönemde gelişmiştir. Sosyal harcamalar, bireylerin asgari yaşam seviyelerini kabul edilebilir bir düzeye taşıyarak toplumsal eşitsizlikleri gidermeyi amaçlar. Çalışma, 1988-2019 dönemine ait verileri kullanarak sosyal harcamaların GSYH üzerindeki etkilerini incelemiştir. Elde edilen bulgular, sosyal harcamaların ekonomik büyümeyi pozitif yönde etkilediğini göstermektedir. Özellikle dar gelirli kesimlere yapılan transfer harcamaları, bu kesimlerin marjinal tüketim eğilimlerinin yüksek olması nedeniyle tüketim harcamalarını artırarak ekonomik büyümeyi desteklemektedir. Johansen eşbütünleşme testi sonuçları, sosyal harcamalar ile GSYH arasında uzun dönemli bir ilişki olduğunu ortaya koymaktadır. Hata Düzeltme Modeli (VECM) sonuçları ise sosyal harcamalardaki değişimlerin uzun dönemde ekonomik dengeye katkıda bulunduğunu göstermektedir. Gelir dağılımı üzerinde de olumlu etkileri olan sosyal harcamalar, toplumsal eşitliği artırıcı rol oynamaktadır. Bu bulgular ışığında, sosyal harcamaların artırılması ve etkin bir şekilde yönetilmesi, ekonomik büyüme ve toplumsal refahın artırılması açısından büyük öneme sahiptir.

Objetivo: Determinar a prevalência da antigenemia criptocócica através do teste CrAg-LFA em pessoas que vivem com HIV (PVHIV) e que estão em tratamento com antirretrovirais, correlacionando com a detecção do Cryptococcus spp. no líquido cefalorraquidiano (LCR). Métodos: O estudo foi realizado de abril/2021 a julho/2021 em uma amostra de 250 PVHIV, em atendimento no ambulatório de referência em HIV/AIDS do Hospital Universitário Gaffrée e Guinle (RJ). Avaliamos a prevalência das infecções e correlação das faixas de linfócitos T CD4+ com a ocorrência de neurocriptococose, cujo diagnóstico era definido por cultura microbiológica a partir do LCR ou por exame micológico direto. A análise estatística consistiu do teste Kappa de Cohen com classificação de Landis & Koch (1977). Para tanto, utilizamos o programa SPSS 27 for Mac IBM. Resultados: Detectamos a prevalência da antigenemia criptocócica em 8,8% dos pacientes (IC 95% 5,5-13,3%). A concordância entre a antigenemia criptocócica e a neurocriptococose demonstrou-se robusta (0,875; p=0,0001). Conclusão: A prevalência de antigenemia na população de estudo e a concordância na detecção do antígeno criptocócico, no soro e LCR, indicam a necessidade da realização do CrAg-LFA no soro, nas PVHIV, independente da carga viral ou vigência de TARV.
