Student-teacher conferences and video-recorded microteaching sessions in developing pre-service teachers' teaching competences
Authors: Marhaban Saiful , Kasim Usman , Syamaun Arifin , Sulistyo Teguh
Published: February 2023

The present study highlighted the importance of pre-service teachers’ teaching competences in English Language Teaching (ELT). Facts show that empowering pre-service teachers is very important, but inspiring lecturers to implement a suitable teaching model takes time. Thus, this study aimed to determine how student-teacher conferences and video-recorded microteaching sessions (VRMS) affected pre-service teachers’ competences. Besides, the self-reflection of the pre-service teachers after watching their own teaching performance video and the conference with the lecturer was also investigated to see their behaviors towards their teaching performances. This mixed-method study involved one group and applied three main instruments to collect data: interviews (student-teacher conferences), checklists of teacher self-evaluation forms, and teaching practicum performance tests using a scoring rubric adapted from Brown (2000). There were 20 participants who were taking the Microteaching Course at the Department of English Education, Universitas Syiah Kuala, Banda Aceh, Indonesia. The study was conducted in one consecutive semester consisting of 16 meetings, each of which was 200 minutes long (4 credits). The results proved that student-teacher conferences and VRMS stimulated pre-service teachers’ teaching competences. Pre-service teachers grew their self-reflection after watching their own teaching videos and understood their strengths and weaknesses after getting student-teacher conferences. It implies that the improvement of their teaching competences resulted from a process involving the willingness to do self-reflection and the lecturer’s help in understanding what areas the pre-service teachers had to improve. The implications of the study are also presented and discussed in this paper.

Published: February 2023

This study aims to find out the problems faced by student teachers in an internship program in designing lesson plans at schools. A lesson plan is one of the essential instructional designs that should be considered to achieve a successful teaching and learning process. For teachers, a lesson plan is a guideline that will be used in teaching to achieve learning objectives. This research used a qualitative method. The participants were selected by using purposive sampling. They were seven students of the English Education Department of Universitas Syiah Kuala who were taking an internship program. The data collection was carried out through document analysis and interviews. The results showed that all student teachers strived to design their lesson plans based on the 2013 Curriculum. There were several problems faced by the students, such as (1) formulating the indicators of competency achievement, (2) writing learning objectives, (3) finding suitable materials, (4) selecting learning methods, (5) choosing learning media and resources, (6) formulating activities, and (7) creating an assessment. The results of the interview also revealed the same. Thus, it is recommended that student teachers should receive more training, both theoretically and practically, in designing the lesson plan based on the 2013 Curriculum as required by the Ministry of Education in Indonesia.

Authors: Nasir Chairina , Ufairah Azzah
Published: February 2023

Writers as language users are fully aware that idioms are powerful tools to get messages across. This research is to examine idiomatic expressions in Arafat Nur’s novel Tanah Surga Merah (2017). It is intended to find out the types of idiomatic expressions and the contextual meaning used in the novel. The research design of this study was qualitative research. This study was aimed at finding out the seven types of idioms based on O’Dell and McCarty’s (2017) theory and Baker’s (2018) translation strategies for contextual meaning. The techniques of data analysis were data reduction, data display, and data verification suggested by Miles et al. (2018). After collecting and analysing the data from the novel, three types of idioms were found, with 30 idioms in total. There are eight idioms in the form of verb+object/complement/adverb or 27% of the share, 19 idioms in the form of compound, which is the most frequent type of idiom used with a percentage of 63%. Lastly, there were only three idioms in the form of simile, or 10% of the share. Idioms in the form of prepositional verbs, binomial (word+word), trinomial (word+word+word), and whole clauses or sentences were not found in this novel. In a nutshell, the contextual meaning of those idioms in the novel varied based on the situations and the contexts which function to describe feelings, emotions, and conditions in conversations. Paraphrasing is the most suitable translating strategy for equal meaning in English as it provides meaning in the context of the idioms found in the novel, and compound idioms are mostly used by the author to describe the characters in the novel.

Published: February 2023

The phenomenon of poor English language proficiency among Indonesian students suggests revisiting the instructional methods that have long been commonly used in English as a foreign language (EFL) classrooms. This long-lasting problem makes it essential for English practitioners to seek alternative approaches paving the ground for the EFL learners to reach more promising achievements. One of the approaches that may fill in this lacuna is Pair-Interaction Model (PIM). Therefore, the present study was an attempt to disclose the effects of PIM on fostering Indonesian EFL learners’ proficiency compared to the Grammar-Translation Method (GTM). For this purpose, a total of 90 first-year English students from three renowned universities in South Sulawesi, i.e. Hasanuddin University, Indonesian Moslem University situated in Makassar, and the Muhammadiyah University of Pare-Pare, were selected using a purposive sampling technique. The participants went through a pre-test, an intervention, and a post-test procedures. Findings revealed that the English proficiency of the participants who received instructions based on the principles and procedures of PIM significantly improved at the end of the interventions. This improvement was particularly seen in the participants’ grammar knowledge and speaking skills. The findings offered strong evidence that PIM can be implemented in the Indonesian classes to foster EFL learners’ proficiency. The study concludes by offering some implications for relevant stakeholders and opening up some avenues for further research.

Indonesia ranked second as the country most frequently hit by tsunamis, earthquakes large and small often occur in Indonesia. The earthquake in Palu-Donggala, South Sulawesi in 2018 with a magnitude of 7.4 had generated a tsunami as high as 3-5 m, and the epicenter was in the north of the bay which resulted in the death toll and the destruction of infrastructure. In minimizing losses and casualties, structural disaster mitigation in the form of coastal buildings consisting of mangroves and vegetation as natural protection and sea walls as coastal reinforcement can be the right step to anticipate the vulnerability of the Palu Bay area. This study aimed to analyzed the level of attenuation in coastal structures and determine the best alternative for tsunami disaster mitigation planning. The test was carried out with a physical model using (wave flume) at the Balai Pantai Laboratory with a total of 48 times of testing with variations of three wave generation targets (0.07 m, 0.09 m, and 0.11 m), depth (0.40 m, 0.414). m, and 0.428 m) and the width of the vegetation (0.40 m, 0.70 m, and 1 m) which are divided into 24 scenarios. The results of the physical model test showed that the presence of coastal structures has a significant effect on the characteristics of the transmission waves, and the speed. The existence of mangrove forests and vegetation has succeeded in reducing wave transmission by 20-100%, also being able to reduce wave speed up to 100% significantly in the relative water level (Mean Water Level), reducing up to 87% at average elevation (Sea Water Level) ), and reduce up to 22% at the highest tide state (High Water Level).

The action by stages was introduced into the Croatian civil procedure law by the 2003 Law on Amendments to the Civil Procedure Act, with the aim of increasing the general quality and efficiency in providing legal protection and improving the general functioning of civil procedure. Courts do not keep records of the number of received actions by stages lawsuits, but available case law indicates that difficulties do exist and thus the need for a serious approach to this issue. The aim of this paper is to point out the importance of understanding the legal institute of action by stages with an emphasis on its practical application. Participants in court proceedings who apply to the court by filing an action by stages must be aware of its legal effects at certain stages of civil proceedings. On the other hand, the court must also ensure the lawful application of this institute so as not to commit procedural violations that would jeopardize the litigants’ legal position. In this regard, the analysis of this legal institute is necessary in order to remove practical doubts and ensure its legal function. Research results of this paper have confirmed that practical doubts should not be neglected and that there is room to consider a more efficient solution than the one in existence.
POLOŽAJ RADNIKA U POSTUPKU PREUZIMANJA DIONIČKIH DRUŠTAVA

Published: February 2023

A takeover bid is one of the main methods of acquiring voting control in a listed company. By acquiring the voting control, the majority shareholder gains the power to influence or determine corporate decisions, which can significantly affect not only the position of the shareholders, but also the position of a much wider circle of stakeholders. It is not to be disputed that takeovers significantly affect workers’ positions; therefore the paper analyses the regulatory framework governing the position of workers in takeover procedures in European and Croatian law. The analysed solutions are compared with the solutions adopted in Slovenian and French law. While Slovenian legislation has adopted solutions that are very similar to Croatian, the French legislator has given greater rights to workers both in the takeover procedure and in the post-bid period. The paper also presents the results of a survey conducted on the Croatian capital market on the use of workers’ rights granted to them by the Croatian Takeover Act. It is concluded that workers exercise these rights, but to an insufficient extent.
MOBBING IN THE WORKPLACE AMONG RESPONDENTS - TEACHERS EMPLOYED IN SECONDARY SCHOOLS OF THE CITY OF POZEGA, POZESKO-SLAVONSKA COUNTY, REPUBLIC OF CROATIA
Authors: Bjelić Gaćeša Dragana
Published: February 2023

Initial research into the phenomenon of workplace mobbing dates back to 1972 and was conducted in Sweden. Of exceptional importance for determining the existence of mobbing, is a proper understanding of the behaviour that can be subsumed under the term as well as its clear distinction from the usual conflicts in the workplace and various forms of harassment. The aim of the present paper is to check the existence of mobbing in the workplace among respondents – teachers employed in secondary schools in the City of Pozega, Republic of Croatia. In this sense, the paper is divided into two parts in terms of content: theoretical and special part. In the theoretical part of the paper, mobbing will be conceptually defined and its distinction towards harassment as a form of discrimination will be analyzed. The theoretical part of the paper includes an overview of earlier research into mobbing in the EU and the Republic of Croatia and an analysis of the procedure for obtaining legal protection in the case of mobbing in accordance with applicable regulations of the Republic of Croatia. A special part of the paper is dedicated to the analysis of the results collected by the conducted empirical research. The mentioned research included 350 teachers employed in six secondary schools in the City of Pozega. These are the Gymnasium, the School of Economics, the Technical School, the School of Crafts, the School of Agriculture and Food and the Music School. At the end of the paper, the author presents concluding remarks in which she gives recommendations for improving the detected problems.

Authors: Wang Yunong , Sun Zhanxue , Cai Lingling , Zhang Fengchuan
Published: February 2023

Objectives

This network meta-analysis assessed the relative efficacy and safety of six common photoelectric therapies including 1064-nm neodymium-doped yttrium aluminum garnet (Nd: YAG), fractional carbon dioxide laser(FSCO2), fractional micro-plasma radiofrequency(Plasma), micro-needling fractional radiofrequency (MRF), 1550nm or 1540nm erbium-glass non-ablative fractional laser (NAFL) fractional erbium-doped yttrium aluminum garnet (Er: YAG).

Methods

A comprehensive search to identify relevant studies was conducted using four electronic databases. Outcome measures were extracted based on subjective and objective indexes, including the dermatologists’ evaluation(DE), the patients’ overall satisfaction(PS), VAS score, and Postinflammatory hyperpigmentation (PIH).

Results

Eleven published clinical research studies, involving 405 patients were included in this study. Ranking of DE from large to small is as follows: Nd: YAG, FSCO2, Er: YAG, Plasma, NAFL, MRF. In terms of PS, the rand from high to low can be described as follows: Er: YAG, Nd: YAG, FSCO2, Plasma, NAFL, MRF. In connection with the sequencing of adverse events, pain severity from slight to severe as follows: Er:YAG, Nd:YAG, FSCO2, NAFL, MRF, Plasma. The probability of having PIH are presented in order from lowest to highest as follows: MRF, Plasma, Nd: YAG, NAFL, Er: YAG, FSCO2.

Conclusion

FSCO2 remains the mainstream of potentially curative treatment, then again Nd: YAG and Er: YAG require greater efforts to prove their superior effectiveness. NAFL might be appropriate for mild and moderate improvement with its strengths of good tolerance while Plasma fits into patients with higher pain thresholds but an expectation of higher results. MRF has not given expression on absolute predominance for the present.

Multiparametric magnetic resonance imaging for characterizing renal tumors: A validation study of the algorithm presented by Cornelis et al.
Authors: Pietersen Pia Iben , Lynggård Bo Madsen Janni , Asmussen Jon , Lund Lars , Nielsen Tommy Kjærgaard , Pedersen Michael , Engvad Birte , Graumann Ole
Published: February 2023

Objectives:

In the last decade, the incidence of renal cell carcinoma (RCC) has been rising, with the greatest increase observed for solid tumors. Magnetic resonance imaging (MRI) protocols and algorithms have recently been available for classifying RCC subtypes and benign subtypes. The objective of this study was to prospectively validate the MRI algorithm presented by Cornelis et al. for RCC classification.

Material and Methods:

Over a 7-month period, 38 patients with 44 renal tumors were prospectively included in the study and received an MRI examination in addition to the conventional investigation program. The MRI sequences were: T2-weighted, dual chemical shift MRI, diffusion-weighted imaging (DWI), and dynamic contrast-enhanced T1-weighted in wash-in and wash-out phases. The images were evaluated according to the algorithm by two experienced, blinded radiologists, and the histopathological diagnosis served as the gold standard.

Results:

Of 44 tumors in 38 patients, only 8 tumors (18.2%) received the same MRI diagnosis according to the algorithm as the histopathological diagnosis. MRI diagnosed 16 angiomyolipoma, 14 clear cell RCC (ccRCC), 12 chromophobe RCC (chRCC), and two papillary RCC (pRCC), while histopathological examination diagnosed 24 ccRCC, four pRCC, one chRCC, and one mixed tumor of both pRCC and chRCC. Malignant tumors were statistically significantly larger than the benign (3.16 ± 1.34 cm vs. 2.00 ± 1.04 cm, P = 0.006).

Conclusion:

This prospective study could not reproduce Cornelis et al.’s results and does not support differentiating renal masses using multiparametric MRI without percutaneous biopsy in the future. The MRI algorithm showed few promising results to categorize renal tumors, indicating histopathology for clinical decisions and follow-up regimes of renal masses are still required.

Tibial Tubercle Avulsion Fracture (TTAF) is an uncommon disease. They are usually found during childhood-adolescent age and described as non-traumatic fractures during running with direct physis affection. In order to avoid growth complications, which would lead to harmful consequences for the patient, an accurate diagnosis following a solid treatment has to be carried out. We describe a case report of a 12-year-old football player boy with a tibial tuberosity avulsion following a conservative treatment. Pharmacological treatment and a rehabilitation program was prescribed with a satisfactory evolution. Even though one of the physician consulted suggested open reduction and internal fixation, the medical staff for his team decided a more conservative approach which came out as an adequate management for this case. After a two years follow up the evolution was successful and the player was able to perform every football specific activity pain free and without any kind of limitation.
Compactness Matters: Improving Bayesian Optimization Efficiency of Materials Formulations through Invariant Search Spaces
Authors: Baird Sterling , Hall Jason R. , Sparks Taylor D.
Published: February 2023

Would you rather search for a line inside a cube or a point inside a square? Physics-based simulations and wet-lab experiments often have symmetries (degeneracies) that allow reducing problem dimensionality or search space, but constraining these degeneracies is often unsupported or difficult to implement in many optimization packages, requiring additional time and expertise. So, are the possible improvements in efficiency worth the cost of implementation? We demonstrate that the compactness of a search space (to what extent and how degenerate solutions and non-solutions are removed) affects Bayesian optimization search efficiency. Here, we use the Adaptive Experimentation (Ax) Platform by Meta and a physics-based particle packing simulation with eight or nine tunable parameters, depending on the search space compactness. These parameters represent three truncated log-normal distributions of particle sizes which exhibit compositional-invariance and permutation-invariance characteristic of formulation problems (e.g., chemical formulas, composite materials, alloys). We assess a total of four search space types which range from none up to both constraint types imposed simultaneously. In general, the removal of degeneracy through problem reformulation (as seen by the optimizers surrogate model) improves optimization efficiency. We recommend that optimization practitioners in the physical sciences carefully consider the trade-off between implementation cost and search efficiency before running expensive optimization campaigns.

Published: February 2023

Industrial Kraft black liquor from maritime pine was oxidized in aqueous, alkaline medium, under air, at 150C, with or without CuO/TiO2 catalyst. The oxidation products were analyzed by HPLC, elemental analysis, SEC, FTIR, NMR. The results showed the depolymerisation of lignin, the formation of phenolic compounds in low yields, with vanillin being the major phenolic compound, and the formation of aliphatic compounds in higher yields, with formic, succinic and tartronic acids being the major identified aliphatic compounds. The presence of catalyst favoured the formation of phenolic and aliphatic compounds. Replacing Kraft black liquor by pure Kraft lignin as a starting material did not enhance the performances of catalytic oxidation, showing that lignin purification may not be necessary in our conditions. Switching from a batch reactor to a fixed bed reactor, working under similar conditons, did not increase the yields in oxidation products but increased the productivity. This work shows the potential of Kraft black liquor to produce a large panel of compounds, including phenolics, aliphatic acids and oxidized lignin, all being valuable in chemical industry.
Molecular Descriptor and Criterion for Efficient N-Doping of Organic Semiconductors
Authors: Xu Chunlin , Wang Dong
Published: February 2023

Precursor dopants have been extensively applied for n-doping of organic semiconductors (OSCs) to address the trade-off between dopant reducibility and stability. N-DMBI-H derivates are believed as one of the most successful air-stable n-dopants. Two doping mechanisms, i.e., hydrogen atom transfer (HAT) and hydride transfer (HYT), have been suggested but the dominance of them remains controversial. In this work, we rationalize the thermodynamics and kinetics of HAT and HYT reactions between N-DMBI-H derivates and a variety of OSCs and conjugated polymers based on the density functional theory, and manifest that the HYT via concerted electron and hydrogen atom transfer is the most viable doping mechanism. We find two linear relations between the free energy change of HYT, \Delta G_HYT, and the electron affinity (EA) of OSCs as well as the ionization energy (IE) of dopant radicals, D, and the Brnsted-Evans-Polanyi relation between the \Delta G_HYT and the activation barrier of HYT, \Delta G^≠. By correlating important thermodynamic and kinetic parameters of HYT to facile properties of OSCs and dopants, molecular descriptors of n-doping are uncovered. Furthermore, an EA(OSC) - IE(D) > 1.0 eV criterion is proposed for achieving a high doping efficiency based on the requirement \Delta G_HYT < 0. Finally, new quinoid-structure polymers with EA > 4.0 eV and good backbone planarity are designed as potential n-type OSCs. The molecular descriptors and criterion discovered provide a simple and operable way to speed up the development of n-type OSCs and dopants by high-throughput screening and machine learning technique
∆-Machine Learning for Quantum Chemistry Prediction of Solution-phase Molecular Properties at the Ground and Excited States
Authors: Chen Xu , Li Pinyuan , Hruska Eugen , Liu Fang
Published: February 2023

Due to the limitation of solvent models, quantum chemistry calculated solution-phase molecular properties often deviates from experimental measurements. Recently, ∆-machine learning (∆-ML) was shown to be a promising approach to correcting errors in the quantum chemistry calculation of solvated molecules. However, this approach's applicability to different molecular properties and its performance in various use cases are still unknown. In this work, we tested the performance of Δ-ML in correcting redox potential and absorption energy calculations using four types of input descriptors and various ML methods. We sought to understand the dependence of ∆-ML performance on the property to predict, the quantum chemistry method, the data set distribution/size, the type of input features, and the feature selection techniques. We found that ∆-ML can effectively correct the errors in redox potentials calculated by density functional theory (DFT) and absorption energies calculated by time-dependent DFT. For both properties, the ∆-ML corrected results showed less sensitivity to the DFT functional choice than the raw results. The optimal input descriptor depends on the property, regardless of the specific ML method used. The solvent-solute descriptor (SS) is the best for redox potential, whereas the combined molecular fingerprint (cFP) is the best for absorption energy. A detailed analysis of the feature space and the physical foundation of different descriptors well explained these observations. Feature selection did not further improve the Δ-ML performance. Finally, we analyzed the limitation of our Δ-ML solvent effects approach in data sets with molecules of varying degrees of electronic structure errors.

DNA-stabilized silver nanoclusters (AgN-DNAs) are known to have one or two DNA oligomer ligands per nanocluster. Here, we present the first evidence that AgN-DNA species can possess additional chloride ligands that lead to increased stability in biologically relevant concentrations of chloride. Mass spectrometry of five chromatographically isolated near infrared (NIR) emissive AgN-DNA species with previously reported X-ray crystal structures determines their molecular formulas to be (DNA)2[Ag16Cl2]8+. Chloride ligands can be exchanged for bromides, which redshifts the optical spectra of these emitters. Density functional theory (DFT) calculations of the 6-electron nanocluster show that the two newly identified chloride ligands were previously assigned as low-occupancy silvers by X-ray crystallography. DFT also confirms the stability of chloride in the crystallographic structure, yields qualitative agreement between computed and measured UV-vis absorption spectra, and provides interpretation of the 35Cl-nuclear magnetic resonance spectrum of the (DNA)2[Ag16Cl2]8+. A reanalysis of the X-ray crystal structure confirms that the two previously assigned low-occupancy silvers are, in fact, chlorides, yielding (DNA)2[Ag16Cl2]8+. Using the unusual stability of (DNA)2[Ag16Cl2]8+ in biologically relevant saline solutions as a possible indicator of other chloride-containing AgN-DNAs, we identified an additional AgN-DNA with chloride ligands by high-throughput screening. Inclusion of chlorides on AgN-DNAs presents a promising new route to expand the diversity of AgN-DNA structure-property relationships and to imbue these emitters with favorable stability for biophotonics applications.

Doğal ve kültürel miras ögelerinin olumsuz etkilere maruz kaldığı günümüzde hem yerel hem de küresel anlamda kültürel miras ögelerinin gelecek nesillere sağlıklı bir biçimde aktarılması, kent planlama gündeminde önemli birmeseledir. Bu nedenle kültürel miras ögelerinin sürdürülebilir bir biçimde korunması ve gelecek nesillere aktarılabilmesi için kültür rotası kavramı önemli bir planlama aracı olarak ortaya çıkmaktadır. Kültürel mirasın bir rota kurgusu içinde oluşturulması hedefi, hem kültürel miras ögelerinin korunması için hem de alternatif ve bilinçli bir turizm hareketinin oluşması açısından önemlidir. İstanbul, çeşitli tarihsel dönemlere ait miras öğelerini bünyesinde barındırmaktadır. Bu nedenle kültürel miras ögesi açısından zengin olan bu şehirde, bir kültür rotası kurgulamasının hem mirasın korunması hem de mirasın gelecek nesillere aktarılabilmesi için önemli bir yanı bulunmaktadır. İstanbul Tarihi Yarımada’da bugüne kadar herhangi bir kültür rotası kurgulanmadığından ve düzenlenen rotaların daha çok bir gezi rotası niteliği bulunduğundan, konuya kültür rotası oluşturma çerçevesinden bakılmasının önemi büyüktür. İstanbul Tarihi Yarımadası çeşitli dönemlere ait, özellikle içme suyu teminine yönelik miras öğeleri açısından zengin bir alandır. Bu nedenle, bu çalışmada, İstanbul Tarihi Yarımada’da bulunan su mirası öğelerinden açık ve kapalı sarnıçlar kültür rotası oluşturma potansiyeli yönüyle, CBS analizlerine dayalı bir saha çalışması kapsamında incelenmiş ve değerlendirilmiştir. Günlük hayatta görünürlüğü azalmış bu su mirası öğelerine yönelik hem mekânsal planlamada görünürlüğünün arttırılması hem de sürdürülebilir biçimde korunarak gelecek nesillere aktarılması hedeflenmiştir. Araştırmanın en önemli bulgusu, İstanbul Tarihi Yarımada’da açık ve kapalı sarnıçların su mirasına yönelik bir kültür rotası kapsamında değerlendirilebileceğidir. Buna göre sarnıç temalı kültür rotasının oluşturulması hem miras koruma çalışmaları hem de mekânsal planlama çalışmalarında, su mirası öğelerinin sürdürülebilir bir biçimde görünürlüğün arttırılması ve korunarak gelecek kuşaklara aktarılması için bir fırsatı oluşturacaktır.

Background

As record cases of Omicron variant were registered in Europe in early 2022, schools remained a vulnerable setting undergoing large disruption.

Aim

Through mathematical modelling, we compared school protocols of reactive screening, regular screening, and reactive class closure implemented in France, in Baselland (Switzerland), and in Italy, respectively, and assessed them in terms of case prevention, testing resource demand, and schooldays lost.

Methods

We used a stochastic agent-based model of SARS-CoV-2 transmission in schools accounting for within- and across-class contacts from empirical contact data. We parameterised it to the Omicron BA.1 variant to reproduce the French Omicron wave in January 2022. We simulated the three protocols to assess their costs and effectiveness for varying peak incidence rates in the range experienced by European countries.

Results

We estimated that at the high incidence rates registered in France during the Omicron BA.1 wave in January 2022, the reactive screening protocol applied in France required higher test resources compared with the weekly screening applied in Baselland (0.50 vs 0.45 tests per student-week), but achieved considerably lower control (8% vs 21% reduction of peak incidence). The reactive class closure implemented in Italy was predicted to be very costly, leading to > 20% student-days lost.

Conclusions

At high incidence conditions, reactive screening protocols generate a large and unplanned demand in testing resources, for marginal control of school transmissions. Comparable or lower resources could be more efficiently used through weekly screening. Our findings can help define incidence levels triggering school protocols and optimise their cost-effectiveness.
Coordination of Classical and Dynamic Inequalities Complying on Time Scales
Authors: Sahir Muhammad Jibril Shahab
Published: February 2023

In this research article, we present extensions of some classical inequalities such as Schweitzer, Pólya–Szegö, Kantorovich and Greub–Rheinboldt inequalities of fractional calculus on time scales. To investigate generalizations of such types of classical inequalities, we use the time scales Riemann–Liouville type fractional integrals. We explore dynamic inequalities on delta calculus and their symmetric nabla versions. A time scale is an arbitrary nonempty closed subset of the real numbers. The theory of time scales is applied to combine results in one comprehensive form. The calculus of time scales unifies and extends continuous versions and their discrete and quantum analogues. By using the calculus of time scales, results are presented in more general form. This hybrid theory is also widely applied on dynamic inequalities.
TAŞLICALI YAHYÂ BEY DİVANINDA HAYÂLÎ BEY ELEŞTİRİSİ
Authors: GÜRGEN Arif
Published: February 2023

İnsana ait tüm duygu ve düşüncelerin işlendiği Divan Edebiyatında dile getirilen önemli konulardan birisi de eleştiridir. Divanlarda aşk, tasavvuf, tabiat, kahramanlık konuları işlendiği gibi eleştiri ve tenkit içerikli konularda işlenmiştir. Divan Edebiyatında eleştiri ve tenkitin boyutları çeşitli bir mahiyettedir. Bu makalede ele alacağımız eleştiri ise bir şairin divanında başka bir şairi eleştirmesidir. Eleştiren şair Taşlıcalı Yahyâ Bey, eleştirilen şair ise Hayâlî Bey’dir. Her iki şairde aynı dönemin yani on altıncı yüzyıl şairleridir. Her ikisi de hem kendi dönemlerinde tanınmış hem de şöhretleri günümüze kadar gelmiş şairlerdir. Divan Edebiyatının gelişmesinde ve zenginleşmesinde önemli katkıları olan şairlerdir.

Ancak şunu unutmamak gerekir ki yüksek meziyetli şairlerinde insanî yönleri kendini gösterir. Onlar da diğer insanlar gibi bir başkasına karşı kıskançlık, kızgınlık, dargınlık, rekabet etme duygularına kapılıp bu duygularla hareket edebilirler. Şairler kendilerine ait yaşadıkları bu duyguları da şiirle dile getirirler. Aslında bu durum şairlerin kendilerine karşı duydukları güvenleri ve yanlış bir şekilde sanıldığı gibi kişisel duygu, düşüncelerin divanlarda yer almadığı zannının da yanlışlığını gösterir. Divanlarda bu şekilde şairlerin hayatından ve özel durumlarından izler görülür. Aynı zamanda şairlerin birbirlerinden kopuk olmadıklarını, birbirlerini takip ettiklerini ve bir iletişim hâlinde olduklarının da göstergesidir.

Bu makalede, Yahyâ Bey divanında Hayâlî Bey eleştirisini içeren şiirler tespit edilerek bu şiirlerin tahlili yapılmıştır. Böylelikle bir şairin divanında başka bir şairi hangi açılardan eleştirildiğinin hususları ortaya konulmaya çalışılmıştır. Ayrıca şairlerin bilinip, tanıtılması amacıyla her iki kıymetli şairin hayatları ve edebî şahsiyetleri hakkında bilgi verilmiştir.

Anahtar Kelimeler:Yahyâ Bey, Hayâlî Bey, Divan, Edebiyat, Şiir, Eleştiri.

Published: February 2023

Everyday life «stole» stability and enough time for serious reflection. The future of business is now built on quick decisions, and only the competence of the people who make them, and the people who provide enough analytics to make such decisions, is the key to success.

Insufficient attention to the formation, preservation and exchange of competencies within the company can be a bad symptom of an unstable «tomorrow». This «sickness» is the lack of a knowledge base or knowledge management process.

In this article, the authors analyze existing approaches to effectively building a knowledge exchange process for internal control and audit units as a guarantor of reliable business analytics.
