Authors: Ismail Rafah Rasheed , Al-Abudi Bushra Qassim , Halos Saadiyah H.
Published: November 2024

Dust storms are a common ecological occurrence in many world‘s countries, mainly in dry and semi-dry parts. Dust storms tremendously influence human health, the environment, the climate, and numerous social aspects. In this paper, spatial and temporal analysis, metrological triggers, and trajectory, dust exporting areas of a severe dust storm that occurred in Iraq on May 16, 2022, were investigated. The dust storm's backward trajectory was determined using HYSPLIT model, which is then compared with MODIS and Meteosat satellite images. The weather is then analyzed using the NCEP/NCAR Reanalysis model, and the approximate area of these sources was determined using Landsat 8 satellite image classification method. The results revealed that the HYSPLIT model trajectory of the dust storm agreed with MODIS and Meteosat satellite visuals. The primary dust storm sources and their areas are identified. The first source is from the shared border region between Syria (Rif-Dimasshq) and Jordan (north of Al-Ruwaished), with an area of about 775 km2. The second is from the northwestern regions of Iraq, specifically north of Anbar and south of Nineveh, with an area of about 905 km2.
Comparative Analysis for the Seasonal Variations of the IF2 and T Ionospheric Indices during Solar Cycles 23 and 24
Authors: Garee Huda S. , Hadi Khalid A.
Published: November 2024

In this work, a comparative analysis for the behavior and pattern of the variations of the IF2 and T Ionospheric indices was conducted for the minimum and maximum years of solar cycles 23 and 24. Also, the correlative relationship between the two ionospheric indices was examined for the seasonal periods spanning from August 1996 to November 2008 for solar cycle 23 and from December 2008 to November 2019 for solar cycle 24. Statistical calculations were performed to compare predicted values with observed values for the selected indices during the tested timeframes. The study's findings revealed that the behavior of the examined indices exhibited almost similar variations throughout the studied timeframe. The seasonal variations were adopted to examine the cross-correlation between the studied indices. The seasonal correlation between tested indices demonstrated that the two indices are highly correlated to each other, with determination coefficient (R2) values ranging from 0.991 to 0.998 during solar cycle 23 and from 0.996 to 0.998 during solar cycle 24. Furthermore, the results of the comparative analytical study revealed that the mathematical correlation equation between the tested indices could be described as a first-order polynomial equation. The proposed mathematical correlation formula for these two indices exhibited a high level of accuracy and good fit between observed values and generated datasets for all seasons during both solar cycles 23 and 24.
«Libres», negros y afrocolombianos en la región del Chocó
Authors: Villa William
Published: November 2024

Hasta los años ochenta del siglo XX, las comunidades negras del Chocó se identificaban como «libres», un término que hacía referencia tanto a aquellos que habían logrado su libertad durante la esclavitud, como a los que formaron las bases de la sociedad y cultura negra en la región. Estos «libres», a través de la automanumisión y manumisión, establecieron asentamientos en torno a los centros mineros y crearon un sentido comunitario basado en el parentesco. En la segunda mitad del siglo XX, estas familias adoptaron nuevas formas de organización política y social, logrando dialogar con el Estado sobre sus derechos territoriales, lo que culminó en la Constitución de 1991 y la Ley 70 de 1993. Estos cambios transformaron la forma en que las comunidades negras se representan y narran su historia, haciendo énfasis en sus raíces africanas y en la sostenibilidad de sus ecosistemas. Sin embargo, el reconocimiento territorial otorgado por el Estado no ha evitado la subordinación de estas comunidades a las dinámicas extractivas del mercado, exacerbadas con la titulación colectiva de tierras. Este artículo aborda la transformación radical de estas comunidades a partir de la Constitución de 1991 y la Ley 70 de 1993, que reconocieron sus derechos territoriales y colectivos. Sin embargo, estas políticas de reconocimiento se han visto tensionadas por la expansión de una economía extractiva que, lejos de fortalecer el control territorial de las comunidades negras, ha exacerbado su subordinación a las lógicas del mercado y a actores externos.

Literatura y filosofía. La gaya ciencia de la literatura
Authors: Dumoulié Camille
Published: November 2024

Platón, en la República, afirma que el diferendo que opone a filósofos y poetas es antiguo. Sin embargo, esa historia, en que los unos y los otros se hacen competencia no deja de cobrar actualidad en cada época. Y el diferendo se eleva tanto más por cuanto el delicado parentesco entre los dos discursos no cesa de renovarse, sobre todo en una historia de la filosofía que habrá persistido en un largo sometimiento de la literatura. En el momento en que la filosofía, con Kant y después con el advenimiento del saber absoluto de Hegel, parece al fin triunfar, la historia se voltea irónicamente. Desde el movimiento de las Luces hasta el primer Romanticismo alemán se desarrollan las condiciones de nacimiento de una práctica y una idea nuevas: la literatura, en el sentido propio y actual del término. Retomando el deseo absoluto de la filosofía, esta se convierte en su relevo y su recurso. El acontecimiento histórico de la literatura en su sentido moderno es el punto central de este libro, que aborda también la cuestión más general de las relaciones entre las letras y la filosofía, así como los problemas de método planteados por la lectura filosófica, de los textos literarios. Pero ante todo se propone aquilatar la cuestión del objetivo de la literatura -su finalidad y su ética- poniéndola en perspectiva con los objetivos que pretende asignar la filosofía.

Systemic Lupus Erythematosus (SLE) is an autoimmune disease caused by an autoreactive B and T cell response with loss of immune tolerance to self-antigens. It manifests with asthenia, fever, myalgias, arthralgias, skin rash and fatal organ damage. Dengue is a zoonotic disease caused by the dengue virus (DENV), transmitted by mosquitoes of the Aedes aegypti species. Diagnostic suspicion is made in the presence of acute febrile syndrome with clinical manifestations and demographic history. Confirmation is by detection of the virus by PCR-RT, or of the structural protein NS1. The present case report is a 58-year-old woman with data of lupus exacerbation and with clinical manifestations suggestive of Dengue fever, with a history of travel to an endemic area. The confirmatory PCR-RT test leads to appropriate medical treatment. The importance of the case lies in differentiating the diagnosis in a timely manner.

Authors: Şahin Özgür , Songur Mehmet , Sertkaya Burak
Published: November 2024

Direct investments are an important dynamic for sustainable economic growth and development. Especially developing countries need foreign capital more because their income and savings are not sufficient. Foreign direct investment is becoming increasingly important for sustainable development and stable growth. In Turkiye, national savings are not sufficient to realize investments. In order to increase foreign direct investment inflows, macroeconomic dynamics should be favorable. Therefore, determining the relationship between foreign direct investments and macroeconomic factors will make it more possible to monitor foreign investments. The aim of this study is to determine the determinants of foreign direct investments in Turkiye. In this context, exchange rate, CBRT reserves, inflation, economic growth rate and external debt data are used in this study. The study utilizes annual data for the period 1981-2021. The ARDL bounds test was used in the analysis. Findings show that exchange rate, economic growth and foreign debt are determinants of foreign direct investment.

Asymmetric Effects of Real Exchange Rate on Turkey's Imports: Threshold Value Regression Model
Authors: Yaşar Zaim Reha
Published: November 2024

Determinants of imports are one of the most discussed topics in the foreign trade literature. This study explores the asymmetric relationship between the real exchange rate and imports for Turkey example. The paper employs monthly data spanning from 2013:01 to 2023:06, estimating classical least square estimation and Threshold Regression Models, subsequently comparing their outcomes. The findings highlighted that the relations between imports and real exchange rate are asymmetric. According to the least square estimation model, it was noted that the real exchange rate had a negative impact on imports, aligning with anticipated outcomes. In the threshold regression model, it was seen that movements in the real exchange rate positively affected imports in the model below the threshold, while exerting a negative effect in the model above the threshold. This finding was interpreted as increasing imports by buying the expectation that the exchange rate increases, which are below the internalizable level, may increase further. It is considered essential for policymakers to take into account asymmetric relationships when analyzing the relationships between imports and the exchange rate.
Unraveling the Nexus of Industrialization, Human Development, Democracy, Trade Openness, and Renewable Energy in EU Environmental Degradation
Authors: Erdölek Kozal Özge
Published: November 2024

This study aims to unveil the effects of industrialization, human development, compliance with the rule of law, and renewable energy on CO2 emissions and the ecological footprint of consumption in EU countries over the 1990-2022 period. The empirical findings, based on the MMQR analysis, reveal that the magnitudes of coefficients between factors affecting CO2 emissions and the ecological footprint vary. Industrialization and human development are the main contributors to environmental degradation, while renewable energy use consistently mitigates environmental degradation across all quantiles. Trade openness also mitigates CO2 emissions in all quantiles with a diminishing trend, but the same correlation is only observed in the lowest quantile for the model with ecological footprint. Compliance with the rule of law has a statistically insignificant effect on the ecological footprint; however, in the lowest quantile of CO2 (0.1), the rule of law exacerbates CO2 emissions, whereas in the highest quantile, it has a mitigating effect. While industrialization and human development contribute to both dimensions of environmental degradation, the different impacts of trade openness and the compliance with the rule of law underscore the need for specific strategies in designing policies to mitigate CO2 and ecological footprints from a policy perspective.

Authors: Kaplan Yıldırım Rüya , Kadooğlu Aydın Gülden , Münyas Turgay
Published: November 2024

Para politikası belirsizliği, 2007 küresel ekonomik krizle birlikte hem gelişmiş hem de gelişmekte olan ülkelerde önemli bir sorun haline gelmiştir. Küresel ekonomik krizle başlayan para politikası belirsizlikleri, ülke risk primlerini (CDS) ve döviz kurlarını etkilediği ve finansal piyasalarda oynaklığa yol açtığı tartışmaları gündeme getirmiştir. Bu araştırma, küresel ekonomideki para politikası belirsizliğinin CDS ve döviz kurları üzerindeki etkisini kısa ve uzun dönemde incelemeyi amaçlamaktadır. Bu çalışmada, para politikası belirsizliğinin Çin, Türkiye, Meksika, Brezilya ve Güney Afrika gibi gelişmekte olan beş ülkenin döviz kuru ve ülke risk primi üzerindeki uzun vadeli etkileri incelenmiştir. Analizler kapsamında, panel ARDL sınır testi yaklaşımı kullanılarak, bu ülkelerdeki ekonomik dinamiklerin uzun dönemli ilişkileri ortaya konulmuştur. Elde edilen bulgular, para politikası belirsizliğinin uzun dönemde ülkelerin döviz kurları ve ülke risk primleri üzerinde istatistiksel olarak anlamlı etkileri olduğunu göstermektedir. Ayrıca kısa dönemde, denge mekanizmalarında sorun yaşandığında, ülkelerin risk primlerinden ziyade döviz kurlarının dengeye gelmesinin daha uzun zaman aldığı tespit edilmiştir.

Election and Wallet: The Effect of Election Periods and Consumer Expectations on Consumer Confidence with ARDL and QARDL Model Approach
Authors: Öztürk Zeynep
Published: November 2024

The growing significance of consumer confidence and the explanation of the factors influencing this confidence is an important issue worthy of study. This study aims to examine the effects of election periods and consumer expectations on the Consumer Confidence Index (CCI) in Turkey. To this end, the Autoregressive Distributed Lag (ARDL) and Quantile Autoregressive Distributed Lag (QARDL) models will be employed. Data on the variables in question were collected on a monthly basis from Turkish Statistical Institute (TUIK) over the period spanning 2012:1 to 2024:3. The ARDL model findings indicate that election periods exert a positive and significant influence on the TGE, both in the short run and in the long run. The intention to buy or have a house built and the intention to save have positive and significant effects on the TGE in both the short and long run. Conversely, the intention to buy a car and the cost of living index have a positive and significant effects on the TGE in the short run, but no significant effect was found in the long run. The QARDL model reveals that asymmetry is present, with all variables exhibiting disparate effects across different quartiles. The findings of this study indicate that in order to enhance consumer confidence and guarantee economic stability, it is essential to prioritise the housing market, savings patterns and reducing the cost of living. The development of policies that ensure the sustainability of the confidence and stability created during election periods is crucial. The research offers invaluable insights into ARDL and QARDL models that can inform Turkey's economic policies.
How Do Teachers Perceive Lifelong Learning and Adult Education?
Authors: Bolat Yavuz , Kıyak Ayşe Nur
Published: November 2024

The objective of this study is to explore the perspectives of middle school teachers on the concepts of lifelong learning and adult education. The qualitative research involved 25 middle school teachers, and their responses, gathered through semi-structured interviews, underwent content analysis. Thematic analysis was employed to derive the results. The findings underscore that teachers attribute value to lifelong learning and adult education for various purposes, such as personal development, adaptation to evolving times, sustained learning, quality time utilization, social integration, and meeting educational needs. A consensus within the study group indicates that individuals across professions should engage in lifelong learning beyond their initial undergraduate education. The research reveals that continuous lifelong learning among teachers positively impacts performance, fostering open-mindedness, cultivating versatile thinking, facilitating effective lesson delivery, and improving interaction with students. Identified factors hindering lifelong learning include physical and economic conditions, environmental factors, health issues, motivation, and the repercussions of disasters. Additionally, teacher opinions shed light on shortcomings in lifelong learning and adult education within the Turkish context. Lastly, the study observes a general lack of adequate knowledge among teachers regarding global lifelong learning and adult education activities.
How Do Teachers Survive? Turkish Adaptation of Selection, Optimization, and Compensation Strategies Scale
Authors: Çatak Seda , Konaklı Tugba
Published: November 2024

The continuous development of professional competencies and active retention of teachers in the field, stemming from alterations in their professional life cycles, are intrinsically connected to the necessity of lifelong learning for teachers. The model of selection, optimization, and compensation (SOC) strategies can be used to gain insight into the ways in which teachers manage their resources to remain in the profession, how they adapt to their professional lives in the context of lifelong learning, and how to develop effective policies to support the professional development of teachers. Although previous research has emphasized the primary factors that influence teachers' professional development and motivation, there is a scarcity of research on the strategies that teachers use to maintain their employment. In order to fill this gap, this study aims to adapt the Selection, Optimization, and Compensation Scale (SOCQ) (Zacher & Frese, 2011), which emphasizes the strategies that teachers use to remain effective in their professional lives, into Turkish. The sample of the study consisted of 299 teachers working in schools in Çekmeköy district of Istanbul province. In the adaptation process of the scale, Turkish translation, back translation, cross-checking, and Turkish face validity stages were followed. Confirmatory Factor Analysis (CFA) was conducted to evaluate the construct validity of the scale. The CFA revealed excellent fit indices for the scale. Consisting of 12 items and three dimensions, the reliability of the scale was evaluated using Cronbach Alpha internal consistency coefficient and composite reliability coefficient (CR). The internal consistency coefficient was 0.81, while the CR value was 0.902. The study's findings demonstrate that the Turkish version of the SOCQ is a valid and reliable tool for assessing teachers' use of SOC strategies.

Authors: Yudistira Andhika , Asmiragani Syaifullah , Satriawan Ery , Aristoteles Aristoteles , Kristanto Harris
Published: November 2024

Objectives:

Epidural fibrosis is a common complication following laminectomy, contributing to failed back surgery syndrome characterized by back pain and radiculopathy. Despite ongoing research, no consensus exists on the best method to prevent epidural fibrosis. This animal study aimed to compare the effectiveness of autologous fat grafts and methylprednisolone as single and combination therapies in preventing epidural fibrosis.

Methods:

Four groups of rats, each containing 7, underwent different treatments post-lumbar laminectomy: A control group, a group receiving methylprednisolone in the epidural space, a group receiving an autologous fat graft, and a group receiving both methylprednisolone and an autologous fat graft. After 6 weeks, the formation of epidural fibrosis was evaluated through histopathological examination based on the classification. The degree of epidural fibrosis was analyzed.

Results:

The autologous fat graft group exhibited the lowest degree of fibrosis (Grade 1). Comparisons between this group and the others showed a significant difference (P < 0.05). No significant difference was observed between the control, methylprednisolone, and combination groups (P > 0.05).

Conclusion:

The study demonstrated a significant reduction in histological epidural fibrosis using autologous fat grafts compared to methylprednisolone and their combination in animal models. Histological analysis indicated that autologous fat grafts resulted in a lower degree of fibrosis following laminectomy.

Для некоторых небольших значений длины периода получены оценки на степени соответствующих фундаментальных S-единиц, а также некоторые необходимые условия, которым должны удовлетворять элементы указанных дробей, чтобы при заданных параметрах существовали нетривиальные S- единицы.

Let Q be the field of rational numbers, Q (x) be the field of rational functions of one variable, f be a square-free polynomial of odd degree equal to 2g + 1, g> 0. Suppose that for a polynomial h of degree 1 the discrete valuation defined by this polynomial has two nonequivalent extensions to the quadratic extension of the field L = Q (x) (√f). There is a connection between the properties of the decomposition of special elements of L into a continued fraction and S-units defined by finite and infinite valuation. For some small values of the length of the period, estimates are obtained for the degree of the corresponding fundamental S-units, as well as some necessary conditions that the elements of these fractions must satisfy, so that for non-trivial S-units there exist non-trivial S-units

This research has examined consumer behavior and the use of Shopee PayLater in online shopping for students in Sepakat 2 Southeast Pontianak. Shopee Paylater is known as a service for users to shop online on the Shopee platform without having to pay directly. The type of research that has been used is a descriptive qualitative research method. This research has focused on consumer behavior, factors, and the impact of using PayLater services in online shopping by students in Sepakat 2 Southeast Pontianak analyzed using Jean Baudrillard's consumption society theory. The results of the research have shown that there are two factors in the consumptive behavior of students using Shopee Paylater, namely: internal factors caused by emotional feelings, habits, social status, lack of financial awareness, impulsivity, and lifestyle while in terms of external factors caused by promotions and discounts, convenience access, attractive advertising, flexible payment features, reviews and testimonials, personalization technology, loyalty and rewards programs and exclusive offers. Thus, consumer behavior using Shopee Paylater can become a problem if users do not pay attention to their spending limits and financial capabilities. It is important to use Shopee Paylater wisely by considering financial needs and capabilities.
Rules Describing CO2 Activation on Single-Atom Alloys from DFT-meta-GGA Calculations and Artificial Intelligence
Authors: Rivera-Arrieta Herzain I. , Foppa Lucas
Published: November 2024

Single-atom alloys (SAAs) arise as a promising concept for the design of improved CO2 hydrogenation catalysts. However, from the immense number of possible SAA compositions and structures, only a few might display the properties required to be useful catalysts. Thus, the direct, high-throughput screening of materials is inefficient. Here, we use artificial intelligence to derive rules describing surface sites of SAAs that provide an effective CO2 activation, a crucial initial step to convert the molecule into valuable products. We start by modeling the CO2 interaction with 780 sites of flat and stepped surfaces of SAAs composed by Cu, Zn, and Pd hosts via high-quality DFT-mBEEF calculations. Then, we apply subgroup discovery to determine constraints on key physical parameters, out of 24 offered candidate descriptive parameters, characterizing subgroups (SGs) of surface sites where chemisorbed CO2 displays large elongations of its C-O bonds. The key identified parameters are free-atom properties of the elements constituting the surface sites, such as their electron affinity, electronegativity, and radii of the $d$-orbitals. Additionally, the generalized coordination number is selected as a key geometrical parameter. The SG rules are used to identify promising alloys among more than 1,500 possible single-atom and dual-atom alloys. Some of the promising alloys predicted by the SG rules were explicitly evaluated by additional DFT-mBEEF calculations and confirmed to provide a significant CO2 activation.

Published: November 2024

La Enfermedad de Von Willebrand adquirida (EVW adquirida) es un trastorno hemorrágico  adquirido poco frecuente, con características clínicas y de laboratorio similares a la Enfermedad de Von Willebrand congénita. Asociándose con enfermedades hemato-oncológicas, autoinmunes, cardiovasculares y tumores sólidos. Las gammapatías monoclonales constituyen un grupo heterogéneo de trastornos caracterizados por la proliferación de linfocitos B en los últimos estadios madurativos o células plasmáticas que preservan la capacidad de producir una inmunoglobulina (Ig) monoclonal o alguno de sus componentes. Como consecuencia, se produce la aparición de una paraproteína o componente M (CM) en suero y/o orina que estará formado por la misma cadena pesada o ligera, y por regiones variables idénticas. Se presenta el caso de una mujer de 57 años, que se presenta con un síndrome hemorragíparo, alteración de la crasis en su vía intrínseca, donde se diagnostica EVW adq secundaria a Mieloma Múltiple (MM) con CM IgM 5,9 g/dl. El tratamiento tuvo como objetivos detener el sangrado, prevenir complicaciones y abordar precozmente la patología hemato-oncológica causante. Para su abordaje requirió la realización de recambios plasmáticos terapéuticos (RPT) que tuvieron un rol de acción terapéutica temprana y eficaz con excelente tolerancia. Ante el diagnóstico se inició rápidamente poliquimioterapia siendo ésta una paciente candidata a trasplante de progenitores hematopoyéticos. El objetivo de la presentación de este caso clínico es destacar la importancia de un correcto y oportuno diagnóstico ante la sospecha clínica de una coagulopatía secundaria a una enfermedad hemato-oncológica subyacente. Por lo que hacemos énfasis en el abordaje multidisciplinario.
