Bu çalışmada, Kızılırmak Nehri’nin farklı zamanlarda taşımış olduğu alüviyal depozitler üzerinde oluşmuş Bafra Ovası delta ovasında, sol sahilinde yer alan bazı örnek mera alanları topraklarının fiziko-kimyasal özelliklerinin ve fiziksel kalite indekslerinin belirlenmesi ile kalite indekslerinin Coğrafi Bilgi Sistemleri yardımıyla dağılım haritalarının oluşturulması amaçlanmıştır. Seçilen üç örnek mera alanları, saha gözlemleri, denize olan uzaklıkları ve tane boyu fraksiyonel değişimleri gibi özellikler dikkate alınarak seçilmiştir. Araştırma kapsamında yüzey (0-20 cm) ve yüzey altı (20-40 cm) olmak üzere mera alanlarından toplam 90 adet toprak örneği alınmış ve toprakların temel verimlilik parametreleri, bazı makro ve mikro bitki besin elementi analizleri ile fiziksel toprak kalite parametrelerinden olan toprak kabuk indeksi ve toprak sıkışabilirlik indeksi (CI, soil compactability index) değerleri belirlenmiştir. Ayrıca, bu kalite parametrelerinin mera alanlarında konumsal dağılım haritalarını üretmek amacıyla on beş farklı interpolasyon modeli uygulanmıştır. Elde edilen sonuçlara göre, mera toprakları genellikle killi bünyeye sahip olup hafif alkali topraklardır. Toprakların organik madde ve kireç içerikleri oldukça değişken olup, besin elementleri yönünden özellikle mangan haricinde genellikle yeterli düzeyde olduğu belirlenmiştir. Mera alanlarında, Mera 1 ve Mera 2’de CI değerleri alanların güney kesimlerinde az bir alanda dağılım gösterirken, Mera 3’te toprak sıkışabilirlik riski daha fazla dağılım göstermiştir. Toprak kabuk indeksi de mera alanlarında gerek yüzey gerekse de yüzey altı topraklarında CI da olduğu gibi benzer bir dağılım deseni sergilemiştir. Mera topraklarında sıkışmanın önlenmesi veya daha az etkilenmesi için özellikle uygun zamanlarda otlatmanın yapılması gerekir.
Where the Decisions are Made? Urban Geography of Corporate Headquarters in the United States
Authors: Kiryukhina A. , Dokhov R. , Puzanov K.
Published: March 2024

The locations of Fortune 500 corporate headquarters in U.S. cities spectacularly changed between 1970 and 2020. Previous researchers pointed on the diversity of business and financial services, agglomeration effects of the headquarters themselves and the role of airports as the leading factors in the localization of headquarters in the largest cities. However, factors that allow smaller agglomerations to also localize headquarters were also emphasized: proximity to the companies’ production facilities, the growth of passenger air connectivity, the opportunity to obtain more favorable local tax and regulatory conditions, more flexible cost of living for employees. Based on the Fortune 500 rating data, we analyzed the changing detailed geography of the headquarters locations of the largest American companies by MSAs by calculating the dynamics of the Shannon diversity index by economic sectors over the past 40 years. The share of headquarters of the largest corporations located in the top 50 MSAs has remained almost unchanged, but since 2000 the top 5 MSAs have been declining, while the share of MSAs in the second population quartile has increased. This trend towards deconcentration and the rise of second-order agglomerations contradicts S. Sassen’s hypothesis on the concentration of headquarters in several largest cities. The reasons for the deconcentration seem to be associated with the rise of new economic centers in the cities of the US South and West and the relocation of the headquarters of existing F?500 companies to this new centers, as well as the concentration of new industries in new places, not in the key centers of old industries. The economic diversity of headquarters has also undergone significant changes. If in 1980 the MSA New York was significantly ahead of all the others in terms of the number of headquarters and their diversity index, then by 2019 MSA Chicago was significantly closer to it in terms diversity index. At the same time, other agglomerations of Megalopolis (MSAs of Bridgeport, Richmond, Washington, etc.) of the Northeast of the United States, since 2000, have increased the diversity of headquarters, demonstrating independent growth dynamics despite the location in close proximity to the dominant MSA New York. They, as well as the fast-growing MSAs of Miami, Phoenix, San Jose, Denver, Raleigh and Winston-Salem, by 2019 showed the greatest industry diversification. Mono-specialization is not generally typical of large concentrations of headquarters, exceptions are the center of oil production, oil refining and chemical industry Houston, car manufacturing capital of Detroit and the center of Silicon Valley San Jose, the rapid growth of industrial diversity of which, however, did not allow reaching average diversity indicators.

This review paper delves into the multifaceted aspects of pineapple cultivation, focusing on morphology studies, harvesting challenges, and mechanization efforts. Pineapple, renowned for its commercial value and unique flavor, holds a prominent position in global agriculture, with India alone producing 19.64 lakh tonnes annually. However, the hilly terrains of regions like northeastern India pose significant hurdles to traditional harvesting methods, necessitating innovative solutions. Understanding the morphology of pineapple plants is crucial for optimizing cultivation practices and designing efficient harvesting equipment. Insights from various studies shed light on leaf structure, fruit maturity, and growth patterns, providing valuable information for engineering tailored solutions. Mechanization endeavors, including semi-mechanized harvesting machines and semi-manual harvesters, demonstrate promising results in improving efficiency and reducing labor-intensive practices. Despite challenges such as increased crop losses and operational costs, continued research and development in mechanization hold the key to sustainable pineapple cultivation. This paper underscores the importance of integrating morphology studies and mechanization efforts to address the unique challenges faced by pineapple farmers, particularly in hilly terrains, and highlights the need for ongoing innovation to ensure the long-term sustainability of pineapple cultivation.
Exploring Staffing Patterns and Multilingual Classrooms in Teaching Japanese as a Foreign Language
Authors: Luchenko Olha , Kovinko Karina
Published: March 2024

Multilingual classrooms are becoming more common worldwide due to increasing mobility. Teaching foreign languages using the mother tongue in multilingual classrooms has become problematic; some of the significant concerns in Japanese language acquisition – such as the high contextuality of the language, vocabulary and kanji learning – make the direct teaching method confusing for many students, especially at the beginner and elementary levels. This article provides the preliminary results of a study carried out as a component of a more extensive empirical research project on instructional languages in classrooms teaching Japanese as a foreign language. It aims to gather, analyse and synthesise data from a survey conducted at a supranational level. The results of the first two sections of a questionnaire containing closed and open-ended questions were used for a quantitative analysis of the profile of Japanese language instructors with a focus on finding possible connections. The wide geographic distribution of the respondents (274 teachers from fifty-seven countries and regions) made it possible to collect data from a more representative sample and draw meaningful conclusions about the spread of multilingual classrooms that would be impossible in smaller-scale research. The study’s primary results show the proportion of multilingual classrooms among countries in different regions and across different educational stages, the distribution of Japanese language instructors in various educational stages depending on the highest level of formal education attained, and the proportion of part-time instructors working in different academic institutions.

Published: March 2024

Green leaf volatiles (GLVs) are important in giving grape a fresh and green aroma. But the changes in GLVs during the phenological development of grapevines are not well known. This study analysed the GLVs and transcription levels of associated biosynthetic genes in six grape species from the Loess Plateau region at five stages of maturation. Thirteen GLVs were detected, showing unique patterns for each grape type at various growth phases. The primary components in six grapes were (E)-2-Hexenal, (E)-2-Hexen-1-ol, and Hexanal. With the exception of Cabernet Franc in 2019, the overall GLV contents of the six types generally increased during growth and development, peaking or stabilizing at harvest. And Sauvignon Blanc, Cabernet Gernischt, and Cabernet Sauvignon exhibited higher total contents among the varieties. Correlation analysis revealed a strong positive correlation between the levels of Hexanal, 1-Hexanol, (E)-2-Hexen-1-ol, (Z)-3-Hexenyl acetate, Nonanal, and (E, E)-2,6-Nonadienal and the expression of VvHPL and VvAAT genes in the LOX-HPL pathway. Specifically, VvHPL emerges as a potential candidate gene responsible for species-specific differences in GLV compounds. Comprehending the changing patterns in the biosynthesis and accumulation of GLVs offers viticulturists and enologists the opportunity to devise targeted strategies for improving the aromatic profile of grapes and wines.

Published: March 2024

As a major coal country, China faces the issue of significant gas emissions during the coal mining process. This study aims to improve the utilization efficiency of mine gas, reduce greenhouse gas emissions, and promote the low-carbon and green transformation of the coal industry. A 10kW gas regenerative thermal oxidation (RTO) experimental system was constructed. The effects of initial methane concentration, low-temperature flue gas proportion, and operating load on combustion temperature, methane oxidation rate, high-temperature flue gas energy, and system thermal efficiency were studied. The results show that when the combustion temperature is below 600°C, the CH4 combustion reaction cannot proceed effectively, and the system temperature continuously decreases and cannot be maintained stable. The experiment determines the stable operating methane concentration range of RTO. In this experimental system, the lower limit of the initial methane concentration is 0.28%, corresponding to an 86% methane oxidation rate. As the initial methane concentration decreases, the combustion temperature also decreases, and the methane oxidation rate follows suit. The higher the low-temperature flue gas proportion, the higher the combustion temperature, and the system thermal efficiency and output heat decrease with the increase of the low-temperature flue gas proportion. This experiment explores multiple factors affecting regenerative thermal oxidation, providing an basis for ensuring the safe and stable operation of the system and optimization. Improving the thermal insulation and heat exchange performance of the storage body can expand the lower limit of the initial methane concentration, thereby increasing the stability and thermal efficiency of the system.

Published: March 2024

The declining and aging population, as well as the downsizing of households, poses problems for the simultaneous occurrence of vacant houses and the construction of new housing units. The objective of this study was to examine countermeasures for the future occurrence of vacant houses. The relationship between population, households, vacant houses, and newly constructed housing was reviewed according to prefecture, and the occurrence of vacant houses and distribution of newly constructed housing were mapped out. The results revealed that the increase in the number of elderly single-person households is a source of vacant houses, while middle-aged single households tend to promote the construction of new housing due to the lack of housing stock. In Setagaya ward, Tokyo, one of the reasons for the increase in new housing construction may be that many of the elderly single households have old wooden detached houses facing qualitative problems. In Wakayama central city, it was inferred that old, detached houses built for households with children during an economic growth period do not meet the needs of middle-aged single households, due to factors such as age, size, and floor plan, which has promoted vacancy and new construction, resulting in a stagnation of the housing cycle.
A Time-to-Digital Converter for Reducing Redundant Counting of SS ADC in High-Speed CmCMOS os Image Sensor
Authors: Li Ziyi , Gao Zhiyuan
Published: March 2024

To reduce the redundant counting of TDC in high-speed applications and thus reduce power consumption, a TDC architecture is proposed to quantify the difference between two adjacent rows of pixel signals. This structure can remove the identical part between two rows of pixel signals by adjusting the start and stop signal of the TDC, which will reduce the number of flipping of D flip-flops in the TDC. In the 110nm CMOS process, simulation results show that this design achieves an effective number of bits (ENOB) of 4.72 bits and a Figure of Merit (FoM) of 104.7 fJ/step - 162.3 fJ/step with a power consumption ranging from 60 µW to 93 µW. Compared with traditional counting methods, the proposed TDC can reduce counting power consumption by 30%.

Published: March 2024

The research on the excavation mechanical properties of underpass tunnels has already had certain results, but fewer of them consider the effects of dynamic and static loads on the excavation mechanical properties of underground tunnels at the same time, especially the lack of research cases of double-line highway tunnels with angled underpasses of existing railway tunnels. In this paper, based on the tunnel project of the new double-line Shiqian Highway Tunnel passing under the Hurong Railway at an oblique angle, the mechanical parameters of the rock body in the cross-tunneling area under the influence of static and dynamic load coupling are obtained by using the disturbance quantification coefficients and the Hoek-Brown criterion based on the method of over-advanced geological prediction and the investigation of the surrounding rock on the palisade face, and the engineering-scale finite element model is constructed and the mechanical characteristics of the excavation in the tunnel of the double-lane highway tunnel passing under the existing railroad under the influence of the static and dynamic loads are analyzed. The results show that: the new tunnel rock movement law for the top of the arch sinking, bottom plate bulging, side wall to move outward, the height and width of the arch and bottom plate arch with the tunnel excavation and increase, the side wall rock displacement effect is smaller; left and right lines of the tunnel disturbed area of the rule of change is similar; the existing tunnel bottom plate displacement is more than the top plate and the left and right side walls by the excavation of the time step influence is larger. Typical profile displacement is mainly determined by the distance from the excavation surface; the new tunnel in the four types of calculation conditions of the rock disturbance angle is the same; the existing tunnel roof and side wall Von Mises stress extreme occurs in the tunnel structure, the bottom plate there are pressure relief and pressure-bearing areas; based on the displacement control criteria, the recommended upper and lower step blasting method.

Published: March 2024

Luminescent carbon dots (CDs) were locally synthesized in the core of CYTOP fibers using IR femtosecond laser direct writing (FLDW), a one-step simple method serving as a post-treatment of the genuine fiber. This approach enables the creation of several types of modifications such as ellipsoid voids. The CDs and photoluminescence (PL) distribute at the periphery of the voids. The PL spectral properties were studied through Excitation Emission Matrix in the visible range and excitation/emission spectrum in UV/visible range. Our finding reveals the presence of at least 3 distinct luminescent species, facilitating a broad excitation range extending from UV to green, and light emission spanning from blue to red. The average laser power and dose influence the quantity and ratio of these luminescent CD species. Additionally, we measured the spatially resolved lifetime of the luminescence during and after the irradiation. We found longer lifetimes at the periphery of the laser-induced modified regions and shorter ones closer to the center, with a dominant lifetime ~ 2ns. Notably, unlike many other luminophores, these laser-induced CDs are insensitive to oxygen, enhancing their potential for display or data storage applications.

One of the most encouraging avenues to attain the objectives of sustainable development, energy security, and environmental conservation is to enhance the integration of renewable energy into the generation of electricity. In pursuit of this goal, the Jordanian government intends to expand investments in the green energy sector, with solar and wind energy poised to play a key role in satisfying energy demands and cultivating an environmental sustainability. This paper aims to examine the distinctive dynamics, challenges, obstacles, and potential solutions corresponding to the establishment of community solar and wind farms in Jordan suburban areas. It aims to highlight the opportunities and barriers influencing the track of sustainable energy adoption in the country. Through a comprehensive analysis of the Jordanian context, the goal is to extract insights that can guide policies and practices. Additionally, the findings may serve as a valuable benchmark for other regions confronting similar challenges on their pursuit for a sustainable energy future.
Hybrid AI-Analytical Modeling of Droplet Dynamics on Inclined Heterogeneous Surfaces
Authors: Demou Andreas D. , Savva Nikos
Published: March 2024

This work presents a novel approach for the study of the movement of droplets on inclined surfaces under the influence of gravity and chemical heterogeneities. The developed numerical methodology uses data-driven modeling to extend the applicability limits of an analytically derived reduced-order model for the contact line velocity. More specifically, while the reduced-order model is able to capture the effects of the chemical heterogeneities to a satisfactory degree, it does not account for gravity. To alleviate this shortcoming, datasets generated from direct numerical simulations are used to train a data-driven model for the contact line velocity, which is based on the Fourier neural operator and corrects the reduced-order model predictions to match the reference solutions. This hybrid surrogate model, which comprises of both analytical and data-driven components, is then integrated in time to simulate the droplet movement, offering a speedup of five orders of magnitude compared to direct numerical simulations. The performance of this hybrid model is quantified and assessed in different wetting scenarios, by considering various inclination angles and values for the Bond number, demonstrating the accuracy of the predictions as long as the adopted parameters lie within the ranges considered in the training dataset.
Energy and Exergy Analyses of an Innovative Heat Recovery System from the LNG Regasification Process in Green Ships
Authors: Bruno Roberto , Ferraro Vittorio , Bevilacqua Piero , Barone Piofrancesco
Published: March 2024

Despite being stored at 113 K and atmospheric pressure, LNG cold potential is not exploited to reduce green ships’ energy needs. An innovative system based on three Organic Ranking Cycles integrated into the regasification equipment is proposed to produce additional power and recover cooling energy from condensers. A first-law analysis identified ethylene and ethane as suitable working fluids for the first and the second ORC making available freshwater and ice. Propane, ammonia and propylene could be arbitrarily employed in the third ORC for air-conditioning. An environmental analysis that combines exergy efficiency, ecological indices and hazard aspects for marine environment and ship’s passengers, indicated propylene as safer and more environmentally friendly. The exergy analysis confirms more than 20% of the LNG potential can be recovered from every cycle to produce a net clean power of 76 kW, whereas 270 kW can be saved by recovering condensers' cooling power to satisfy some ship needs. Assuming the sailing mode, a limitation of 162 kg in LNG consumptions was determined, avoiding the emission of 1584 kg of CO2 per day. Marine thermal pollution is reduced by 3.5 times by recovering the working fluids' condensation heat for the LNG pre-heating.
Online Review Analysis from a Customer Behavior Observation Perspective for Product Development

Published: March 2024

Observing customers is one of the methods to uncover their needs. By closely observing how customers use products, we can indirectly experience their interactions and gain a deep understanding of their feelings and preferences. Through this process, companies can design new products that have the potential to succeed in the market. However, traditional methods of customer observation are time-consuming and labor-intensive. In this study, we propose a method that leverages the analysis of online customer reviews as a substitute for direct customer observations. By correlating Customer Journey Map (CJM) with online reviews, this research establishes a verb-centric analysis that produces a CJM based on online review data. Various Text analysis techniques were utilized in this process. Through empirical data analysis, we validated that indirect observation based on customer reviews can be performed more efficiently than traditional methods. Additionally, we observed that the customer behavior VOC (Voice of Customer) identified during the CJM mapping process offers unique insights that are distinct from traditional product feature-centric review analyses. To verify the usefulness of these behavior VOC, we evaluated the quantitative analysis results of the same reviews through product development experts. Experts recognized these customer behavior VOC as useful information for developing new products.
Traces of Necromantic Divinatory Practices in the Picatrix
Authors: Hamvas Endre Ádám
Published: March 2024

In the famous medieval magical manual called Picatrix, the unknown author describes the phenomenon of magic with the term nigromantia. As is well known, the original meaning of the Greek term necromantia has a more concise meaning. It is used for a special kind of divination, i.e., divination through the parts of a cadaver and the conjured spirit of the dead. Seemingly in the Picatrix, no necromantic ritual can be found; moreover, the author stresses that his main goal is pious, i.e., to find the path leading to the ultimate source of the universe, the one and only God. In my paper, I show that on some pages of the Picatrix, there are traces of divinatory practices that may be connected to the original meaning of the term nigromantia. In the third book of the manual, descriptions of some interesting rituals attributed to the pagan Sabeans of Harran and their teacher, the god Hermes can be found. During the practices, the magician involved conjured spirits of the heavenly bodies and powers as well. Because of this, by looking closely at and analyzing the given text, it is possible to piece together a complex web of necromantic and demonic divinatory rituals.

Published: March 2024

Urban parks in South Jakarta are the main component of green open spaces which act as habitat for birds in the cities. Aim of this study was to determine the diversity of bird species around the South Jakarta City Park. The research was conducted in October-November 2021 in the city parks of Spatodea and Tabebuya, South Jakarta. Bird data collection used the point count method, while plant data collection used an inventory system. Results showed that the Tabebuya Park location had 9 species of birds from 8 different families, while in Spatodea Park there were 8 bird species found. The Tabebuya City Park was found to have medium species diversity index value, medium evenness index value and low dominance value index. Spatodea city park had a low value index of species diversity, low evenness value index, and low dominance value index. The highest number of bird species obtained was 7 species in total. The results showed that the urban park area in South Jakarta had low to moderate range of bird species diversity. This could happen because birds in urban landscapes tended to be more sensitive to the presence of certain stratification of vegetation, especially tree stratification.

From year to year, social media users are increasing. This can also be seen from the emergence of social media applications that are growing and the number is more than one. However, along with these developments there are applications circulating which do not have official permits so they are considered illegal. One of them is TikTok cash. The name of this application has the same name as the TikTok social media application which is most popular at number one in the world. Meanwhile, Facebook is in second place. TikTok's fame has not been spared by the presence of information in online media that has emerged regarding the security of the application. The TikTok application is said to have a risky security hole where cyber criminals easily enter user accounts so that they can harm the account owner. To prevent this, the account owner is notified to update the latest TikTok application. Seeing this phenomenon, researchers are very interested in writing about the effect of the TikTok application's security information on online media on the attractiveness of social media users in using the TikTok application. The author uses social media users who are in Jakarta as respondents in this study. The method used in this research is a qualitative method. Data taken from observation, literature study and interviews. Then, this research can draw the following results: the effect of the security information of the TikTok application on online media makes social media users gain insight into the knowledge to use social media properly, comfortably and safely. In addition, respondents are not too concerned about security information in the online media because Check point research also advises TikTok application users to update the latest TikTok application and provide personal data. The attractiveness of social media users using the TikTok application is limited to connoisseurs because there are still things that are more interesting, namely YouTube and Instagram which are safer and attract content.

‘Allāl al-Fāsī and Sahal Mahfudh: Maqāṣid asy-Sharī’a as the Meeting Point of the Different Inclinations Rooted in Sunni Tradition
Authors: Haqqi Muhammad Nashrul , Shofaussamawati Shofaussamawati
Published: March 2024

This article aims to highlight the position of 'Allāl and Sahal in the development of Maqāṣid al-Syar'a theory and its application to political, social, and economic problems. The approach is carried out by examining their intellectual career background, examining the theory of the development of Maqāṣid al-Syar'a theory and how they implement it. As a result, 'Allal and Sahal took different positions about Maqāṣid al-Syar'a, although in the and they produced similar or almost the same legal opinions. They both propose a democratic government, an economy that prioritizes the interests of the community, and social conditions that prioritize the interests of women. The dominant difference lies in the characteristics of the choice of sources that indicate affiliation. ' Allāl more often refers to the Qur'an and Sunnah as recommended by the Salafis. While Sahal more often refers to the fiqh tradition advocated by traditional schools, by accommodating modern theories, such as philosophy and social sciences. At this point, the author argues that the concept of Maqāṣid al-Syar'a is a meeting point for various tendencies rooted in the Sunni intellectual tradition, including the different tendencies espoused by 'Allāl and Sahal.
Hadith Regarding the Law of Tabarruk against Habaib: Living Hadith Study of Gedongsari Prambon Nganjuk Islamic Boarding School

Published: March 2024

The occurrence of pros and cons regarding the law of Tabarruk practice against Habaib requires hadith research on the direction of Tabarruk. Because to know the law requires an in-depth study of the meaning of the hadith text itself. This study aims to provide readers with an understanding of the importance of understanding the text of the Prophet’s Hadith. In addition, they also know the methods used by classical and contemporary scholars in practicing Hadith. This research is field research with a qualitative approach. Gedongsari Islamic Boarding School, the administrators and the students, are the main objects of this research. The primary source for the research theories is the book al-Jami’ ash-Shahih by al-Bukhari. Several works such as al-Mutashaddidun by Ali Jumah Muhammad, Mafahim Yajibu ‘an Tushahhah by Sayyid Muhammad Alawi, al-Mulakhas fi Syarh Kitab at-Tauhid by Fauzan Salih, and Fath al-Majid Syarh Kitab at-Tauhid by Abd Rahman Hasan Alu Syaikh are considered as the minor sources. The Hadith about Tabarruk is a category of valid Hadith that can be used as evidence. Al-Qur’an and hadiths with the same theme also corroborate the Hadith. In practice, the practice of the Tabarruk tradition that has been attached and rooted in the Gedongsari Islamic Boarding School is not all based on hadith encouragement. However, several factors influence these habits. It cannot be separated from this habit from the dogma that the kiais and teachers have taught.
Retainment of U.S. Orthopaedic Surgeons in Academia from 2016 to 2022
Authors: Weintraub Matthew , Ahn David , Herzog Isabel , Mendiratta Dhruv , Zheng Zheshi , Kaushal Neil , Vosbikian Michael , Chu Alice
Published: March 2024

Background:

Academic medical centers greatly benefit from retaining their physicians; that ensures continuity in patient care, enhances resident education, and maintains a pool of experienced clinicians and researchers. Despite its importance, little research has been published on the retainment of academic faculty in orthopaedics. To address this gap, this study investigates the demographic trends of academic orthopaedic surgeons from 2016 to 2022. By analyzing data pertaining to gender distribution, years of practice, research productivity, and institutional rankings, we aimed to gain insights into the factors influencing faculty retainment, institution changes, and new entrants into academic orthopaedics.

Methods:

A retrospective cross-sectional analysis of U.S. academic orthopaedic surgeons affiliated with programs under the Accreditation Council for Graduate Medical Education (ACGME) in 2016 and 2022 was performed. Faculty present in both the 2016 and the 2022 data were classified as being “retained” in academia; those present only in 2016, as having “left” academia; and those present only in 2022, as being “new” to academia. The retained group was then divided into movers (those who moved to other institutions) and non-movers.

Results:

Retained orthopaedists had fewer years of practice, a higher h-index (Hirsch index), and more publications. Non-fellowship-trained orthopaedists had less retainment in academia, and orthopaedists with fellowships in oncology had more retainment in academia. Additionally, movers also had fewer years in practice but an equal level of scholarly productivity when compared with non-movers. Lastly, higher-ranked academic programs retained a greater proportion of orthopaedic surgeons.

Conclusions:

Over the study period, a majority of orthopaedists (56.99%) chose to remain in academia. Those retained tended to be in the earlier stages of their careers, yet demonstrated higher research output. Notably, the representation of female orthopaedists in academic orthopaedics is on the rise. Conversely, lower-ranked programs faced higher turnover rates, highlighting the challenges that they encounter in retaining faculty members.

Clinical Relevance:

Academic medical centers benefit from retaining orthopaedic surgeons by maintaining patient relationships, having consistency in resident education, and building on clinical and research expertise. Likewise, orthopaedists benefit from understanding the trends in current academic employment, in order to optimize career planning decisions.
Forecasting Social Cost of Carbon With Predictive Machine Learning Models for CO₂ And GHG Emissions
Authors: Sarkar Pratyayan , Chowdhury Arindam
Published: March 2024

Purpose - The purpose of this study is to ascertain the connection between oil and gas businesses' carbon emissions and the upkeep of their carbon emission monitoring systems. To forecast the carbon emissions in India, China, and all of Asia, we also want to build a machine-learning model utilizing data on carbon emissions from 1850 to 2021. This study analyses data from “OurWorldInData”over a 170-year span to develop a model that forecasts future carbon emissions in Asia, particularly in India and China.
Design/methodology/approach - After extensive research, we collected data on carbon emissions, monitoring, and statistics from various sources, covering the period from 1850 to 2021. Utilizing SKLearn and Scikit-Learn libraries, we pre-processed the dataset, replaced NaN values, and split it into test and training sets (80% and 20%). Employing linear regression and decision tree regressor algorithms, we forecasted future CO₂ and GHG emissions in China, India, and Asia. The decision tree model outperformed linear regression in predicting emissions accurately. Additional data visualization aided in understanding actual versus predicted emissions.
Findings - 95% is the selected level of confidence. The logistic regression model indicates that p is bigger than alpha. Considering this, we adopt the null hypothesis. The difference between actual and expected data is not very significant, according to the chi-square (2) value of 0.3241, which assesses the disagreement between observed and predicted frequencies of outcomes of a set of events or variables. We concluded that the outcomes produced by the Decision Tree Regressor Algorithm were superior and less error-prone than those obtained by linear regression.
Originality/value - Machine Learning model for forecasting CO2 and GHG emissions. Hypothesis formulation and using Logistic Regression to accept the null hypothesis: Companies monitoring carbon emissions emit less carbon
