Implications of incorrectly determining site index on stand-level management activities and financial returns in older generation loblolly pine plantations
Authors: VanderSchaaf Curtis 
Published: January 2024

Predicting future yields normally requires an estimate of site quality. A commonly used measure is site index (SI). SI is often incorrectly quantified operationally due to the ambiguity associated with selecting “site” trees. Plus, error in the measurement of height itself occurs. This study quantifies the impacts on the number and timing of thinnings, and the final harvest ages, as well as financial returns when incorrectly determining SI. Three values of SI (base age 25 years) were examined using two older generation loblolly pine plantation growth and yield simulation models from the Western Gulf, USA; 16.76 m, 21.34 m, and 25.91 m. Firstly, a particular SI was assumed to be the “true” value, growth and yield estimates were obtained, and financial assessments were conducted. The same process was then conducted again, but assuming that the SI was incorrectly determined by varying positively and negatively the SI by up to 1.22 m from the assumed “true” value. For these older generation plantations, incorrectly determining SI did impact the age of the first thinning by as much as 5 years. In some cases, errors of +/- 1.22 m in SI estimation had little impact on the estimated timing of the first thinning. Errors in SI of up to +/- 1.22 m had little impact on the number of thinnings across economic rotation ages. For both unthinned and twice-thinned stands, final harvest (clearcut) ages differed by as much as 4 years for SI errors up to +/- 1.22 m. These errors led to differences in Land Expectation Value (LEV) up to $406.50 ha-1. Across the three SI (16.76, 21.34, and 25.91 m), differences in LEV ranged from $237.49 to $406.50 ha-1. These differences in LEV could be enough to incorrectly not conduct, or incorrectly conduct, a silvicultural operation such as an herbicide treatment or a fertilization treatment across a rotation, among other treatments.

The purpose of researchis to develop a method for synthesizing models for predicting and diagnosing occupational diseases based on hybrid fuzzy technology, providing an increase in the quality of decision-making in occupational pathology.Methods.It is established that most of the problems related to the topic under study (forecasting, early diagnosis, assessment of the severity and dynamics of the development of professional diseases) belong to the class of poorly formalized problems with fuzzy and incomplete data structure, which are recommended to be solved using the methodology of synthesis of hybrid fuzzy solving rules based on on the interaction of the natural intelligence of doctors and a cognitive engineer with artificial hybrid intelligence. Using the chosen mathematical apparatus, a method for the synthesis of fuzzy models of forecasting and diagnosis of occupational diseases is proposed.Results.As a concrete example, the problem of predicting and diagnosing ischemic heart disease (CHD) in electric train drivers has been solved with the allocation of such classes of conditions as: "healthy and the appearance of CHD is not expected"; "healthy, but the appearance of CHD is expected after the predicted time"; "early stage of CHD"; "CHD disease has been detected". As a result of expert evaluation, it was shown that the confidence in the correct classification is at the level of 0.9. The same result was confirmed by the results of statistical tests on representative control samples in terms of diagnostic sensitivity and specificity.Conclusion. The proposed method of synthesis of hybrid fuzzy models makes it possible to synthesize hybrid decision rules that improve the quality of prediction and early diagnosis of the studied class of diseases both in the presence of training samples and in their absence by compensating for the lack of statistical material by methods of formalization of clinical thinking. As a concrete example, the problem of predicting and diagnosing ischemic heart disease in electric train drivers has been solved. It is shown that the confidence in the correct classification is at the level of 0.9, which allows us to recommend the results obtained for practical use in occupational pathology.

Published: January 2024

The purpose of research is development of a mathematical model of vibration vibrations of an aircraft skin element made in the form of a plate with a two-stage transformation "vibration load parameters – deformation of the plate - change in the wavelength of the optical signal" in order to take into account the number of loading cycles and their characteristics, accumulated fatigue deformation of the plate and its life before the critical state in order to optimize planned repairs and reducing the risks of unpredictable failures associated with fatigue phenomena in the skin material and supporting structures of the aircraft.Methods. The described mathematical model uses the parameters of a harmonic vibration signal as input data and includes a two-stage transformation, firstly, of the parameters of the vibration signal (frequency, amplitude) into the amplitude of the vibration vibrations of the aircraft skin element made in the form of a plate, secondly, the amplitude of the vibrations of the plate in question into a change in the wavelength of the optical signal, the presence of which is caused by the use of fiber-optic technologies that are promising for the construction of modern systems for monitoring and diagnostics of aircraft.Results. The proposed mathematical model allows calculating and analytical methods to estimate the amplitude of forced vibration vibrations of the aircraft skin element, which causes the absence of plate resource consumption due to the effects of loading cycles (there is only natural aging of the material), plate resource consumption in elastic deformation mode, accumulation of fatigue deformation of the sample. The method of evaluating the plate for the resonant effect is given, which indirectly affects the processes of designing the elements of the aircraft skin in terms of weight and size indicators, which largely determine the frequency of natural vibrations of the plate. The resulting deformation of the plate is expressed in a change in the wavelength of the light beam for detection and analysis by the control and diagnostic system of the aircraft, made on the basis of fiber-optic technologies.Conclusion. The proposed mathematical model is designed to assess the residual life of a specific element of the aircraft skin, involves subsequent software modeling to confirm the correctness or refinement of the resulting calculation algorithm.

The purpose of researchis development of a method for controlling muscle fatigue in robotic devices operating in a combined mode.Methods. To calculate the exogenous moment of forces of a robotic device, a surface electromyosignal decoder is proposed, which takes into account the effect of the operator's muscle fatigue. By decoding the electromyosignal, the assisting torque on the servomotors of the robotic device is determined. When calculating the assisting moment, the degree of muscle fatigue is taken into account. The method for assessing muscle fatigue consists in assessing the indicator of synchronism of electromyosignals on synergistic muscles and is based on a hybrid approach to the formation of a decision-making module. The first decision-making module is built on the basis of a neural network classifier, the descriptors for which are formed based on the analysis of the spectra of electromyosignals of synergistic muscles. The second decision module includes two synergy channels per electromyographic channel. The first synergy channel is obtained by amplitude demodulation of the electromyosignal, and the second - by its frequency demodulation. As a result, we obtain two muscle fatigue classifiers, the solutions of which are integrated by the aggregator.Results.Experimental studies of the dependence of the electromyosignal on the magnitude of muscle effort and its duration were carried out, which showed that the relative change in the average RMS index under static load can serve as an objective indicator of the degree of muscle fatigue.Conclusion. The developed method makes it possible to control the mechanical moments on the servomotors of a robotic device adequately to the test muscle load and the functional state of the user's muscles. The method allows for individual adjustment of the neural network classifier block and the fuzzy inference block with subsequent aggregation of their solutions and thus optimize the combined operation mode of the robotic device.
Pedagogiska dilemman vid anonymiserad examination och bedömning
Authors: Bergqvist Rydén Johanna 
Published: January 2024

För- och nackdelar med anonymisering av examinationer har diskuterats i decennier. Det är inte svårt att förstå varför ämnet har varit brännande och att det varit så under lång tid. Frågan har i hög grad varit studentdriven, både i Sverige och internationellt, och har sin grund i oro för bias vid bedömning och betygsättning. I Sverige infördes anonymisering av examinationer vid många lärosäten för 10–15 år sedan. Åtgärden föregicks dock sällan av diskussioner om eventuella pedagogiska konsekvenser. Senare års studier av effekterna av anonymisering, tillsammans med kunskaper om hur examination och bedömning påverkar studenters lärande, visar emellertid att en sådan diskussion bör föras. Forskningen har inte kunnat finna tydliga belägg för att anonymisering har positiva konsekvenser i form av minskad bias vid betygsättning. Det finns dessutom risk att centrala kvaliteter som framåtsyftande återkoppling, bedömning av progression, utvecklandet av lärandeorienterade examinationsformer samt en relationsrik högre utbildning motverkas av en examinationskultur som styrs av anonymiseringskrav. I diskussionen som följer argumenterar jag för en viss försiktighet vad gäller tillämpandet av anonymisering samt efterlyser en nyanserad diskussion där studenters lärande står i fokus.
ENGLISH ABSTRACT
Pedagogical dilemmas when anonymizing examination and assessment
Advantages and disadvantages of anonymisation of assessment procedures have been discussed for decades. It is not difficult to understand why the issue has been on the agenda for such a long time. To a large extent, both in Sweden and internationally, it is the students who request anonymisation in examination procedures, and their demands stem from a concern about bias in assessment and grading. In Sweden, anonymized assessment was introduced at many higher education institutions about a decade ago. The implementation, however, was rarely preceded by discussions about potential pedagogical consequences. Research of later years on effects of anonymisation, as well as knowledge about the effects of assessment on student learning, call for a discussion. Researchers have not been able to find evidence of positive consequences of anonymisation in terms of reduced bias in grading. Instead, there is a risk that central qualities in assessment procedures are undermined by an assessment culture steered by requirements on anonymisation. For example, qualities such as feed forward, assessment of progression, the development of learning-oriented assessment forms and a relationship rich higher education are at risk. In this article, I advocate a certain degree of caution when it comes to the implementation of anonymized assessment methods, and call for a nuanced discussion, focusing assessment as a tool for student learning.

Potato has high potential for food and nutritional security. In India, potato cultivation was spread over different states over diverse agro-climatic conditions. Even though edaphic and climatic conditions are suitable for cultivation in India, national average productivity is very low (24.12 t ha-1) as compared to some of the developed countries in the world. Hence with increasing demand of potato, high quality seed is of utmost importance to increasing the productivity. Quality seed is a critical input in potato cultivation and accounts for about 40–50% of the total cost of cultivation. Most significant constraint in lower productivity is attributed to lack of quality seed tubers especially to small and marginal farmers in India. Varietal purity, seed health, physiological age, prevalence of pest and diseases, change in virus vector relationship and poor knowledge of seed selection and ignorance about Seed Plot Technique are the important aspects which affect the seed potato quality. Pre harvest and post-harvest elements viz selection of variety, area of seed production/climatic conditions, agronomy/ agro techniques for seed production, improving tuber size, rouging, plant protection measures, harvesting, post harvest handling and storage are the important elements which affect quality of seed potato production. Therefore, this review mainly focuses on the above said factors for the quality seed potato production and further enhancement of the productivity.

Published: January 2024

Purpose: This study aims to examine the musical experiences of music teachers in childhood.
Design/Methodology/Approach: The research was conducted using the phenomenology research design within the framework of the qualitative research approach. Participants of the study consist of twenty-three music teachers working in the secondary and high schools affiliated with the Ministry of Education in the Kahramanmaraş province in the 2020-2021 academic year. The research data were collected using a semi-structured interview form and conducted for content analysis.
Findings: Family, teacher, school, and environment play an important role in individuals' musical experiences in childhood. Participants' tendency towards music during childhood is attributed to their parents’ interest in music and encouragement of music in their children, discovery and guidance of the students’ musical talent, the facilities offered by the school, including an appropriate setting for learning music, organization of the musical activities such as choirs and courses at school, and events held by non-governmental organizations.
Highlights: It is seen that music helped introverted and/or shy individuals socialize by allowing them to express themselves better. It was also revealed that the participants interested in music during childhood were self-confident, happy, and peaceful individuals with a wide social circle and without financial concerns.

Authors: MUTLU GÜLBAK Gizem 
Published: January 2024

Purpose: The practicum component of teacher education programs and its active participants, mentor teachers (cooperating teachers) and student teachers, have a special place in teacher education programs. With a focus on the experiences of this practicum dyad, this meta-synthesis aims to describe a broader picture of practicum practices in the Turkish EFL context.
Design/Methodology/Approach: It investigates the recent qualitative studies published between 2012 and 2022 through a meta-synthesis
Findings: The synthesis identified three main themes: (1) challenges, (2) expectations, and (3) appreciation of both members, which were further categorized as practicum-based, profession-based, and school-based.

Highlights: The results provided not only valuable data to inform a mentor training program but also uncovered the concerns experienced by all three groups, which should be carefully examined, and necessary actions should be taken accordingly. Through a review of in-depth qualitative studies related to the experiences of the EFL practicum dyad, it provides a broader lens for the practicum studies conducted in language teacher education programs in Turkey and raised issues to be addressed by supervisors, mentors, student teachers, and policy makers, which could also lead to further inquiries for other teaching contexts.

Authors: OZASLAN Gokhan , ÖZASLAN Aslı 
Published: January 2024

Purpose: The purpose of this qualitative multiple-case study is to understand whether success on the High School Entrance Examination (HSEE) has a motivational effect on subsequent high-stakes exams by viewing it from the perspective of the High Performance Cycle Model (HPC).
Design/Methodology/Approach: Two rounds of interviews were conducted with eight dyads, each consisting of an eighth-grade student and a parent. The first interview took place approximately two months before the HSEE exam and the second approximately six months after the exam. Interview data were subjected to matrix analysis.
Findings: The research results show that consistent with the assumption of the HPC model, three participating students who scored highest on the HSEE expressed a desire to begin preparing for the university exam because they experienced an increase in their self-efficacy. It can be concluded that, consistent with the assumptions of the HPC model, a high score on the HSEE may provide students with self-renewing test motivation.
Highlights: Based on the findings, it is recommended that students be given behavioral and learning goals rather than performance goals, and the HPC model should be used for students' holistic development so that they can demonstrate their potential.
The Constitution, Invasion, Immigration, and the War Powers of States
Authors: Natelson Robert G. , Hyman Andrew T. 
Published: January 2024

Abstract
By express and implied reservation, the Constitution permits states to wage defensive war and take other military action in response to invasion, insurrection, and transnational criminal gangs. This article examines the under-researched area of state war powers and how they interact with federal military and other foreign affairs powers. It also recovers the meaning of the Constitution’s term “invasion” and demonstrates that several judicial decisions have construed that term far too narrowly. The article ends with reflections on justiciability and remedies in state war power cases.

Abstract

Castanea sativa Mill. is an important European tree species that has been used for timber and nut production since Greek and Roman times. In Germany, the species accounts for only a small proportion of forest stands but it is attracting increasing interest due to its possible potential for climate tolerance and resilience. However, the status of German sweet chestnut stands in terms of genetic diversity and adaptive potential is poorly investigated. We took a representative sample of 520 individuals from 13 stands in northern Germany (Mecklenburg Western Pomerania; MWP) and genotyped these at 11 genomic SSRs and EST-SSRs. In addition, we compared our data with the available literature, focusing on the possible origin of the MWP populations. The analysis of genetic structure identified three distinct genetic groups within MWP, suggesting different origins or seed mixtures of various provenances. The comparison with reference data at the EST-SSR FIR059 suggests that the MWP stands originate from the western gene pool. The genetic variation observed in most MWP stands is at approximately the same level as stands in the natural range. Therefore, these stands with high diversity seem to be particularly suitable for further production of seed and plant material in MWP. This study contributes to the understanding of the genetic diversity and origin of sweet chestnut stands outside their natural distribution in MWP. It provides valuable knowledge for the evaluation and conservation of genetic resources of this tree species, which is expected to receive more attention under warmer and drier conditions.

Semakin pesatnya perkembangan teknologi saat ini, dapat memudahkan seluruh kegiatan manusia, sehingga mengakibatkan seluruh aspek tidak bisa lepas dari teknologi tanpa terkecuali bidang keuangan. Dengan berkembangnya teknologi diiringi juga dengan dikenalnya berbagai instrument investasi. Setiap melaksanakan investasi tentu akan selalu ada berbagai resiko yang menyertainya termasuk investasi cryptocurrency salah satunya bitcoin. Tidak seperti mata uang konvensional, bitcoin bersifat tidak desentralisasi sehingga perkembangan harganya tidak dalam pengawasan atau kontrol pihak manapun, dimana jika uang konvensional ada lembaga tertentu yang mengawasi dan mengontrol pergerakannya. Hal tersebut mengakibatkan harga nilai tukar dari bitcoin menjadi tidak konsisten atau tidak stabil. Dengan terdapatnya metode prediksi, pengguna bitcoin bisa menetapkan waktu yang pas untuk menjalankan transaksi. Penelitian ini memiliki tujuan guna memprediksi harga bitcoin dengan menggunakan metode LSTM serta Bi-LSTM. Berdasarkan hasil penelitian diperoleh hasil prediksi terbaik menggunakan metode Bi-LSTM dengan RMSE 1482.73 sedangkan dengan LSTM menghasilkan RMSE sebesar 1768.69 sehingga dapat disimpulkan dari sisi akurasi Bi-LSTM memberikan hasil yang lebih akurat hanya saja dengan Bi-LSTM membutuhkan resourse yang lebih banyak.
