Authors: Vargas Vanesa Madalina , Oancea Marian , Saftiuc Bogdan , Vrana Nicolae , Teodorescu Cosmin Alexandru
Published: August 2022

The pandemic caused an increase in the use of, and demand for digital public services, accelerating the digital transformation, which necessitated rapid development and deployment of various ICT systems. The Authority for the Digitalization of Romania in partnership with Code for Romania developed a number of six digital platforms for better management of the COVID-19 pandemic. They firstly created stirioficiale.ro, a platform that was used by the Romanian government to give Romanian residents trustworthy, up-to-date information about pandemic measures, guidance, and other important information. Following that, another 5 platforms were developed with the help of over 420 volunteers in order for the government to better manage the COVID-19 pandemic, with a total of six platforms forming an ecosystem that would be used by over ten million citizens across the country to access reliable information. The main objective of the article is to observe and interpret the analytics of the official platform datelazi.ro. After a formal request to the Authority for the Digitalization of Romania, the official recorded data was received and analyzed by the authors. The main results of the study show us that the visibility of the platform is low compared to the country’s population. However, due to the consistency of users in the fifth wave of the pandemic, it is reasonable to assume that there is a core use of roughly 10,000 residents who find this platform beneficial for information at this time.
Challenges to the supply chains in the context of COVID-19 pandemic
Authors: Enache Gabriela Ioana
Published: August 2022

Global supply chains have been an important factor in changing the organization of the global goods production and global economy.

The pandemic has also brought negative effects on global supply chains, as we have seen a shortage of workforce and transport systems (maritime, air, land), while demand for mandatory products, such as sanitary ones, was rising. The blocking of supply chains has also affected the process of economic recovery, unbalancing the production sector, and fueling inflation.

During this time, the European Union’s reliance on the foreign imports it had both before the pandemic and after periods of trade imbalance, were brought to light, considerably amplified. Increasing autonomy has been a necessity of these conditions, and in order to optimize the resilience of its supply chains, the European Union is applying politics aimed at a wide diversification of suppliers, development of internal capabilities, support for a multilateral business environment based on a set of well-defined rules, and a good cooperation with the United States of America.

The study carried out an in-depth analysis of relevant literature in order to identify the challenges for both the member-states of the European Union, and for other states such as Japan, the United States of America, South Korea, and Australia in terms of imbalances in the supply chains and dependencies on imports from China. We also identified the best practices and measures adopted during the pandemic that led to major trade imbalances.

The research questions to which this study provides detailed answers to are: “How has the COVID-19 pandemic affected global supply chains?” and “What measures were taken globally in order to overcome the imbalances caused by the pandemic?”

This study offers a clarification on the situation of global supply chains and brings, in the same analysis, a series of good practices and strategies to solve supply chain blockages and reducing the dependency on foreign exports that most states had before the pandemic.
Cyber security and awareness, investing in a culture of safety
Authors: Manoliu Alexandru
Published: August 2022

Cyber security is an investment megatrend: global spending on cyber security increases by 10% every year, three times faster than the global economy. These forecasts can be seen on the upside after the arrival of Covid-19 and the IT tracking systems to monitor the infections that pose privacy and security problems for users. Cyber security is growing more and more and so are venture capital investments in what is the megatrend of the year. The pandemic has contributed to speeding up the digitization process: the consequence is an increasingly uniform distribution of cybercrime throughout the European territory and this reminds us that the lack of a security culture is the vulnerability most exploited by attackers. The Covid-19 pandemic is the cause, albeit indirectly, of this phenomenon. Covid-19 has, in fact, accelerated the digital transformation process and the consequence has been an increase in the criminal phenomenon.
Towards Climate Neutrality via Sustainable Agriculture in Soil Management
Authors: Gancone Agita , Viznere Ruta , Kaleja Daina , Pubule Jelena , Blumberga Dagnija
Published: August 2022

The European Green Deal sets an ambitious target for Europe to reach climate neutrality by 2050. This commitment will be a challenge, particularly in the context of agriculture, as the sector is responsible for sustainable development and food security. However, one of the primary sources of GHG emissions from the agricultural sector is the treatment of soils using nitrogen fertilizers for crops, especially grain crops. This paper aims to assess the GHG mitigation perspective for soil management in the Baltic States and, in particular, to analyse the grain sector in light of sustainable agriculture and towards climate neutrality. To achieve the aim of the study, the analysis was performed in two parts. Firstly, historical and projected GHG emissions of the Baltic States and mitigation measures on agricultural soil management, including cereal growing were analysed as these emissions show a growing tendency. Thus, the study analyses GHG emission trends, including possible mitigation measures for soil management in the Baltic States. The results indicated that for GHG reduction from agricultural soils, some cost-effective measures could be considered for the future, such as the zero-emissions on-farm machinery and equipment, low or no-tillage, or N-inhibitors on pasture. Secondly, as the GHG emissions from cereals increase, potential alternatives to the use of grain production have been explored to assess the highest possible added value from the product use, thus also contributing to GHG reduction. In this regard, according to scientific literature, a survey was created in the form of a questionnaire based on 32 alternatives, 4 large product groups, and 4 criteria for cereal and straw processing. The respondents were requested to provide an assessment of alternatives, and consequently, a multi-criteria decision analysis (MCDA) was performed using the TOPSIS method. The results reveal the best alternatives from each of the product groups consequently is flour from food products, minerals from a pharmaceutical, biogas from a form of transport and reusable tableware from straw-based products, as a possible cost-effective mitigation measure for soil management from the perspective of the development of sustainable agriculture sector and the transition towards climate neutrality
What’s in a Title? Some Remarks on the Semantic Features of Kenning-Like Titles in George R. R. Martin’s A Song of Ice and Fire Series
Authors: Neubauer Łukasz
Published: August 2022

Working on the hugely successful series of novels known collectively as A Song of Ice and Fire, George R. R. Martin is known to have drawn much of his inspiration from real-life events, landmarks in the history of the Middle Ages, such as the Hundred Years’ War, the Wars of the Roses, and the Crusades. It is not known, however, to what degree he actually relies in his work on sources of genuinely medieval provenance, since he himself frequently admits that amongst those that made the biggest impact on his writing are modern works of fiction, such as Maurice Druon’s heptalogy Les Rois maudits (2019 [1955–1977]). It is not impossible, though, that at least some features of Martin’s series have more or less direct parallels in medieval literature. One such element may be so-called kennings, the highly-stylised circumlocutions found in plenty in the poetic works of early Germanic literature and whose diction appears to shine through some of the series’ titles.
La agroecología en disputa: una mirada desde el capital y la economía política
Authors: Paz Raúl Gustavo
Published: August 2022

Objetivo: mostrar las estrategias agroecológicas desplegadas por agroecosistemas de la agricultura campesina, tendientes a captar el trabajo/energía producido por la naturaleza y transformarlo en valor, con la participación escasa o nula del capital en tales procesos. Metodología: el estudio del caso responde a un método de investigación cualitativa a partir de entrevistas y observaciones directas Resultados: los procesos de no mercantilización, la condición bifacética de la mano de obra familiar, los tiempos del capital y los de la naturaleza, el capital como cosa y como proceso, la inmediatez tanto del proceso de trabajo, del producto de trabajo y de la realización del valor de uso conjuntamente con formas de apropiación y gestión comunal de la tierra y recursos asociados, son aspectos que sientan la base para pensar en la agroecología contrahegemónica. Limitaciones: más estudios de caso permitirían abordar estas perspectivas que tienen una fuerte mirada capitalocentrico e integrar y complementar con otras miradas y disciplinas. Conclusiones: comprender la lógica del capital desde su relación con la naturaleza y como la naturaleza puede trabajar para ciertos agroecosistemas, disminuyendo el carácter disciplinador del capital en tales procesos, constituye un tema a considerar para el diseño de políticas por parte de los movimientos sociales.

Authors: Alshurtan Kareema , Al-Tufaif Ali , Alnizari Osama , Aldarwish Hadi , Alshammari Basil
Published: August 2022

Background: Diabetic ketoacidosis and hypoglycemia are two common diabetes complications. Predictors that have been linked with hypoglycemia include the drug that is used in diabetes treatment. Hypoglycemia complications and repeat episodes may be prevented by raising awareness regarding the importance of early condition management. The present study aims at evaluating the level of awareness about hypoglycemic episodes among the Hail general population.
Methods: This cross-sectional study evaluated awareness levels regarding hypoglycemia among the Hail population in Saudi Arabia through a prefilled electronic questionnaire. Consent was obtained from all respondents. Afterward, they were given a questionnaire containing 32 items split into three categories. Data analysis was undertaken through the statistical software IBM SPSS Version 22.
Results: There were 1,011 participants in total. They had a mean age of 32 years old. 586 (57.9%) were female, and 185 (18.8%) were health care workers. 703 (69.5%) displayed an intermediate level of awareness. Just 98 (9.7%) were highly knowledgeable. The study found respondents' age, gender, history of diabetes, and hypoglycemia had a significant association with hypoglycemia awareness. Those with chronic diseases more generally also displayed greater awareness.
Conclusion: The Hail population possesses an intermediate awareness level regarding hypoglycemia. Steps must be adopted to improve community knowledge and attitudes toward hypoglycemia. Diabetes mellitus is an increasingly prevalent condition in Saudi Arabia. Therefore, improving awareness levels can significantly decrease the risk of death from hypoglycemia.
Pensar El País. Conflicto, democracia, cultura y paz
Authors: Valencia Gutiérrez Alberto
Published: August 2022

Las columnas de opinión son consideradas un género fugaz cuya vigencia está supeditada a la periodicidad del medio en que se publican. Las 154 columnas publicadas en este libro, aparecidas en el periódico El País de Cali desde mayo de 1998, fueron escritas con la intención de ir a contrapelo de esta tendencia. Aunque construidas casi todas ellas tomando como referencia una situación particular, aspiran a convertirse en pequeños ensayos con vocación de permanencia en el tiempo. Buscan identificar y recuperar en cada caso concreto un problema de reflexión, de carácter general, que vaya más allá de la coyuntura que les sirve de punto de partida. Además, han sido escritas como una forma de llevar a cabo una pedagogía de la democracia, en todos sus matices: reconocimiento del conflicto y la diferencia, control al uso del poder, derechos humanos, cultura y paz. El ensayo “La democracia: una promesa indefinida de igualdad”, que aparece como Presentación del libro, ilustra con todo detalle el trasfondo intelectual desde el cual se descifran los problemas comprometidos en cada uno de los textos. El lector juzgará si estos dos objetivos se han cumplido.

Published: August 2022

Cases of Omicron-type Covid-19 have increased substantially worldwide. With the opening of the Omicron 68 case as of 30 December 2021, Indonesia has become the fourth largest country in Southeast Asia in terms of Covid cases. Singapore is in the first place, with 134 Omicron instances. This study aimed to find online news discourse regarding the spread of the Omicron variant in Southeast Asia. The method used in this research is van Dijk's Critical Discourse Analysis on online news via Kompas.com, news.abs-cbn.com, and channelnewsasia.com during December 2021. This study concludes that the three media reported the spread of the Omicron variant in the text dimension and tried to bring up vaccination efforts. In the dimension of social cognition, ensuring public health for the sake of survival is the ideology that is built. In the context dimension, the social context is built by providing equal opportunities to all people in getting the right to get vaccinated so that matters relating to health issues also have an impact on the economic aspect in line with the national economic recovery.

Authors: Yoanita Desi , Chertian Vivian Graciela , Ayudia Putu Dinda
Published: August 2022

Currently, Instagram has become one of the most effective mediums for personal branding. Interestingly, celebrities or influencers are not the only ones using it. Gen Z also uses Instagram to present their image as ideal as possible. However, that does not mean they lose their true identity. This generation prefers to have multiple Instagram accounts to express themselves. This study aimed to explore why Gen Z had multiple Instagram accounts, how they chose the followers, and how they conducted online self-disclosure through content categorisation of each account. Through this study, the researchers wished to contribute a deeper understanding of the cyber-self, particularly in communication. A focused group discussion was conducted with 21 adolescents aged 18-20 who live in Java, Bali, Kalimantan, and Sulawesi with varying family backgrounds, education, occupation, and gender. The study found that Gen Z distinguished their account based on the designation they have for each account, what self-aspect they want to display, and it finally affects how they disclose information on Instagram.
Religious issues as a message in political communications during local elections
Authors: Taufiq Amal , Siahaan Hotman M. , Pramono Muhamad Fajar
Published: August 2022

This research focuses on religious issues used as messages in political communication. A campaign is a form of political communication by one of the candidates for local leader dan vice local leader of Gresik regency Sambari Qosim (SQ) in the 2015 regional election. This study employed a qualitative approach; therefore, the researcher used observation, in-depth interviews, and documentation to collect data. The study found that the SQ candidate pair used religious issues as a message in their political campaign because the local vice leader of Gersik Regency, Mohammad Qosim, was the son of a Kyai. Thus, such a strategy made it easier for him to gain sympathy from the voters, who would ultimately determine his choice of the pair. This strategy was implemented due to the socio-cultural community of Gresik Regency, a religious society that considers religion to be sacred, including the figure of a Kyai. As a religious figure, the Kyai must be obeyed and become an example in attitude and behaviour. This condition prompted the SQ candidate to take advantage of religious issues to gain as many votes as possible to win the 2015 regional elections.
Komunikasi simbolik kelompok Gay Semarang
Authors: Pudrianisa Sheila Lestari Giza
Published: August 2022

LBHM survey on 2019 mentioned that LGBT groups often experience stigma and discrimination. Although it is widely discussed, it is not easy to access information about these groups. Thus, the problem focuses on how the Semarang gay group uses symbolic communication so that the public can see the symbols used by the Semarang gay group to interact and communicate. This research uses a constructivism paradigm with the qualitative descriptive method and Symbolic Convergence as the main theory. As a result, fantasy exchange creates various communication symbols that converge in the form of verbal (effeminate language/oral and written) and non-verbal (object language, action language and sign language) and are mutually agreed upon as identities to form group cohesiveness. Bad experiences such as stigma/discrimination are the basis for creating safe and easy-to-understand communication symbols between members in exchanging messages and meanings that become the group's motives.
Approval of the text and its legal applications

The study showed the concept of approval, linguistically and idiomatically, and then the types of approval. It is the desirability of the text (the effect), the desirability of consensus, the desirability of custom or habit, the desirability of necessity, and the desirability of analogy. Approval or is it a matter of establishing the ruling with evidence and not approving, the result of the study was that approbation of the text (the effect) is not considered approbation in the idiomatic sense known to scholars of origins, but rather it is a ruling proven by evidence from the book or Sunnah, taking into account the honorable law for the benefit of the people, and the evidence is not approbation In its fundamentalist sense, which is based on the diligence of the mujtahid in what is not stipulated in the text, it is an act of pure evidence.

Published: August 2022

Objectives:

The anatomical differences of the bony structure of the knee joint in patients with hemophilia were evaluated, and the results were compared with the knees of patients with primary gonarthrosis and no arthrosis.

Material and Methods:

This study reviewed 41 knees in 21 patients (with an Arnold-Hilgartner classification of Stages 4 and 5 hemophilic arthropathy) who underwent total knee arthroplasty in single center. Two control groups including 21 asymptomatic patients (42 knees) and 21 primary knee osteoarthritis patients (42 knees) were formed to compare the measurements with hemophiliacs. Femoral mediolateral width, femoral anteroposterior width, femur and tibia diaphysis width, adductor tubercle-joint line distance, tibial plateau width, and medial and lateral tibia plateau width were measured separately.

Results:

Femoral mediolateral width was significantly narrow comparing with healthy individuals and primary knee osteoarthritis group. Tibial plateau was similar to asymptomatic group but significantly narrow compared with primary knee osteoarthritis group. With the correlation, the tibial plateau measurements and medial and lateral plateau were significantly narrow at hemophilic arthropathy group (P < 0.05). The slope was less in hemophilic patients as compared with asymptomatic individuals (P: 0.001). Hemophilic patients had larger femoral aspect ratios than asymptomatic group but there were no observable differences with the primary osteoarthritis group. For the tibial aspect ratios, hemophilic had a smaller ratio than the primary osteoarthritis group but there were no significant differences with the asymptomatic group.

Conclusion:

Hemophilic knee has a mismatch between femoral and tibial side while comparing with the other groups.

Level of Evidence:

Level IV, cross-sectional study.

Published: August 2022

Limited data are available on the long-term perfusional status of patients who have undergone successful surgery for giant retinal tear (GRT) macula-off rhegmatogenous retinal detachment (RRD). This study examines the long-term outcomes in eyes treated for varying degrees of GRT-associated RRD extensions and compared them with two control groups. Twenty-five emmetropic normal eyes (control emmetropic), 20 healthy myopic eyes (control myopic), and 33 eyes surgically treated for GRT (surgical) were included in this study for a comparison of long-term structural, perfusional, and functional outcomes. The surgical eyes were categorized based on degree of GRT-associated RRD extension: 19 eyes with GRT-associated RRD extension <180° and 14 eyes with extension >180°. The eyes were further separated by whether they required placement of a complementary 360° scleral buckle. The mean age of the patients was 55.18 years and the mean pre-operative evolution of GRT was 2.36 weeks. The average pre- and post-operative best-corrected visual acuities (BCVAs) were 1.90 logMAR and 0.59 logMAR, respectively, which were different with statistical significance. Proliferative vitreoretinopathy resulted in multiple surgeries in nine eyes (27.3%). Long-term post-operative optical coherence tomography (OCT) showed 11 eyes (33.3%) with abnormal foveal contour, 13 eyes (39.4%) with ellipsoid zone disruption, two eyes with dissociated optic nerve fiber layer defects, and 15 eyes (45.4%) with external limiting membrane line discontinuities. OCT angiography yielded abnormal perfusion indices in the surgically treated eyes (P < 0.0001). Correlation analysis found that post-surgical BCVA was negatively correlated with superficial foveal avascular zone area, superficial parafoveal vessel density, and central subfoveal thickness, while positively correlated with choriocapillaris flow area. Our data showed that eyes with GRT-associated RRD have multiple structural alterations in spectral-domain OCT biomarkers that are correlated with visual outcomes. Despite successful retina reattachment without proliferation, management of GRT-associated RRD remains challenging.

Published: August 2022

The limited facilities for physical education (PE) teachers cause learning less varied patterns, so it impacts the development of students' basic movements. This study aims to develop a learning model using the play and games modification concept to facilitate the needs of basic movement at the elementary school level. This research is development research with five stages, namely 1) need assessment, 2) product design selection, 3) product development, 4) implementation, and 5) product evaluation. This research produces a product and investigates the efficiency of that product to facilitate elementary school students’ basic movement fulfillment. The subjects in this study are the physical education teachers from Malang regency, Lumajang Regency, Malang City, Lamongan Regency, Blitar City, and Kediri Regency, East Java, Indonesia. From the six regions, 10 schools are involved as subjects, each of which included 25 teachers.The research results suggest that this learning model with play and games modification concept can be used and facilitate the attainment of elementary school students’ basic movement. Thus, the learning model can be categorized as feasible and can promote the fulfillment of the basic movement needs at the elementary school level. The results have significance for elementary school students. The findings can assist teachers in providing facilities for the basic movement needs of children at the elementary school level.
Vibronic Coupling Effect on the Vibrationally-Resolved Electronic Spectra and Intersystem Crossing Rates of a TADF Emitter: 7-PhQAD
Authors: Lin Sirong , Pei Zheng , Zhang Bin , Ma Huili , Liang Wanzhen
Published: August 2022

Assessing and improving the performance of organic light-emitting diode (OLED) materials require quantitative prediction of rate coefficients for the intersystem crossing (ISC) and reverse ISC (RISC) processes, which are determined not only by the energy gap and the direct spin-orbit coupling (SOC) between the first singlet and triplet excited states at a thermal equilibrium position of the initial electronic state but also by the non-Condon effects such as the Herzberg-Teller-like vibronic coupling (HTVC) and the spin-vibronic coupling (SVC). Here we apply the time-dependent correlation function approaches to quantitatively calculate the vibrationally-resolved absorption and fluorescence spectra and ISC/RISC rates of a newly synthesized multipleresonance-type (MR-type) thermally activated delayed fluorescence (TADF) emitter, 7-phenylquinolino[3,2,1-de]acridine-5,9-dione (7-PhQAD), with the inclusion of the FranckCondon (FC), HTVC, and Duschinsky rotation (DR) effects. The SVC effect on the rates has also been approximately evaluated. We find that the experimentally-measured ISC rates of 7-PhQAD originate predominantly from the vibronic coupling, consistent with the previous reports on other MR-type TADF emitters. The SVC effect on ISC rates is about ten times larger than HTVC effect, and the latter increases the ISC rates by more than one order of magnitude while it slightly affects the vibrationally resolved absorption and fluorescence spectra. The discrepancy between the theoretical and experimental results is attributed to the inaccurate description of excited states calculated by the time-dependent density functional theory as well as not fully accounting for the complex experimental conditions. This work provides a demonstration of what proportion of ISC and RISC rate coefficients of a MR-type TADF emitter can be covered by the HTVC effect, and opens design routes that go beyond the FC approximation for the future development of high-performance OLED devices.
Quantum versus Classical Unimolecular Fragmentation Rate Constants and Activation Energies at Finite Temperature from Direct Dynamics Simulations
Authors: Angiolari Federica , Huppert Simon , Spezia Riccardo
Published: August 2022

In the present work, we investigate how nuclear quantum effects modify the temperature dependent rate constants and, consequently, the activation energies in unimolecular reactions. In the reactions under study, nuclear quantum effects mainly stem from the presence of a large zero point energy. Thus, we investigate the behavior of methods compatible with direct dynamics simulations, the Quantum Thermal Bath (QTB) and Ring Polymer Molecular Dynamics (RPMD). To this end, we first compare them with quantum reaction theory for a model Morse potential before extending this comparison to molecular models. Our results show that, in particular in the temperature range comparable with or lower than the zero point energy of the system, the RPMD method is able to correctly catch the classical-quantum difference. {On the other hand, although the QTB provides a good description of equilibrium properties including zero-point energy effects, it} largely overestimates the rate constants. The origin of the different behaviours is in the different distance distributions provided by the two methods and in particular how they differently describe the tails of such distributions.
NO reduction with CO on low-loaded platinum-group metals (Rh, Ru, Pd, Pt, and Ir) atomically dispersed on Ceria
Authors: Tian Jinshu , Khivantsev Konstantin , Lu Yubing , Xue Sichuang , Zhang Zihao , Szanyi Janos , Wang Yong
Published: August 2022

Low-loaded platinum-group single-atom catalysts on CeO2 (M1/CeO2) were synthesized via high-temperature atom trapping (AT) and tested for the NO + CO reaction under dry and wet condition. The activity of these catalysts for NO+CO reaction follows the order Rh > Pd ≈ Ru > Pt > Ir. For Rh, Ru, and Pd single-atom catalysts, the N2O byproduct is formed but not clearly observed on Ir and Pt cases, which may result from the higher reaction temperature (> 200oC) required for Pt and Ir catalysts. The presence of water can promote the activity of these M1/CeO2 catalysts for NO + CO reaction. Under wet conditions, significant NH3 formation occurred during the reaction, which is due to the co-existence of water-gas-shift reaction on these catalysts. Compared with Pt, Pd and Ir, the Rh and Ru single-atom catalysts show higher selectivity to NH3 species, resulting from the more hydride species on the surface. Among all tested catalysts, Ru1/CeO2 shows the highest production of ammonia and highest CO conversion due to excellent water-gas-shift activity, whereas Pd1/CeO2 shows lowest ammonia production.

An efficient gold(I)-catalyzed intramolecular alkoxylation/double aldol condensation cascade cyclization strategy to synthesize 2,2'-spirobi[indene] derivatives has been developed. The scope of this strategy was examined by using a batch of synthetic alkynone substrates and a possible mechanism was proposed.
Protein control of photochemistry and transient intermediates in phytochromes
Authors: Salvadori Giacomo , Macaluso Veronica , Pellicci Giulia , Cupellini Lorenzo , Granucci Giovanni , Mennucci Benedetta
Published: August 2022

Phytochromes are ubiquitous photoreceptors responsible for sensing light in plants, fungi and bacteria. Their photoactivation is initiated by the photoisomerization of the embedded bilin chromophore, which triggers a large conformational change in the protein. The initial photoisomerization and the following structural changes propagating from the chromophore to the entire protein are controlled by a delicate interplay of interactions between the chromophore and the protein residues. Although the numerous studies, the molecular details of this control remain elusive. Here, we apply an integrated computational approach that combines non-adiabatic and adiabatic molecular dynamics simulations to the Deinococcus radiodurans bacteriophytochrome. Our simulations show that the photoisomerization of the chromophore proceeds through a hula-twist mechanism whose kinetics is mainly determined by the hydrogen-bonding interaction of the chromophore with a close-by histidine. The resulting photoproduct rapidly relaxes in an early intermediate thanks to a stabilizing effect of a tyrosine, and finally evolves into a late intermediate, characterized by a more disordered binding pocket and a weakening of the aspartate-to-arginine salt-bridge interaction, whose cleavage is essential to interconvert the phytochrome to the final active state.

Published: August 2022

Although there is an abundance of methods for the enantioselective synthesis of 2-isoxazolines and 2-isoxazolin-5-ones, relatively few of these approaches have been reported when these heterocycles bear fully substituted stereocenters. In this minireview, we will detail the methods that have been used to successfully accomplish these challenging asymmetric transformations and give insights into their importance, such as allowing access to unique three-dimensional chemical space. The limitations of the currently known reactions will be discussed, as well as highlighting the future developments needed to advance the research field.

This report describes the prosthetic rehabilitation of a patient with a large maxillary defect. It is often risky and difficult to take an impression of a large defect in a single-step procedure. In this study, we present a clinical technique where the maxillary obturator prosthesis was fabricated by combining two methods: conventional processing using an impression followed by relining of the obturator part to improve retention and support of the prosthesis. This report also describes how digital speech analysis using formants of five vowels can be utilized during the relining and adjustment step, resulting in improved patient satisfaction and comfort.

An Overview of ICT and Educational Change: Development, Impacts, and Factors
Authors: Wang Xinran
Published: August 2022

This paper focuses on the development of information and communication technology (ICT) in education, its impact on teaching and learning, as well as the factors that sustain change in education. Since the rise of e-learning in the 1990s, ICT has evolved rapidly in the field of education. Furthermore, ICT is seen as a catalyst for change in education, and its impact on both, students and teachers should not be understated. In addition, the sustenance of these positive changes brought about by ICT should also garner attention. This paper consequently focuses on an overview of the evolution of ICT in the field of education in the last decade or so, its impact on the changes in teaching and learning, as well as the factors that sustain the changes. Through a study of prior literature and reports, the results found that ICT has had a different focus and predicted direction each year from 2009 to the present, as well as significant effects on the content, approach, time, and place of teaching, administration, research process, and roles of teachers and students. Additional factors that influence educational change include funding, equipment software, and personnel expertise. Therefore, this article provides referenceable evidence for further ICT applications in education.

Since 2014, an invasive alien fish species, lionfish, Pterois miles (Bennett, 1828) has been started to distribute in the Turkish Mediterranean Sea coasts and spread out to the Aegean Sea. In the present study, a Cymothoid fish parasite, Nerocila bivittata (Risso, 1816) is reported from the pectoral fin of P. miles caught from the Gulf of Iskenderun (Northeastern Mediterranean) and Bodrum, Turkey (Aegean Sea Coast). This study is the first record of N. bivittata on lionfish P. miles caught from Gulf of Iskenderun. Key diagnostic characters of N. bivittata, some morphological differences observed between the newly collected material of N. bivittata and its previous descriptions, in addition to newly observed additional characters were presented.
First Record of Pempheris rhomboidea (Kossmann & Räuber, 1877) Harvested from Aquaculture Fish Cages
Authors: ÇİFTÇİ Nuray , AYAS Deniz

An individual of Pempheris rhomboidea species was detected in a cage where sea bream was grown in the Mersin Dana Island region. P. rhomboidea is a species of the Pempheridae family distributed in the Indo-Pacific and West Atlantic and is a nocturnal species that inhabit coral reefs and rocky waters. It is known that different wild fish species enter into the aquaculture fish cages where marine fish are grown and grow together with the aquaculture species. There is no previous record of this species obtained from aquaculture cages. The total length and weight of the individual in the cage were 12.6 cm and 23.938 g. Considering the mesh size of the cage, it is estimated that this individual entered the cage in the juvenile period. At the end of the 11-month aquaculture period, it was determined that the individual reached a length close to the maximum length that the species can reach in its natural habitat. It was determined that some morphometric characteristics of the individuals harvested from the cage were similar to individuals caught in nature. The ability of the nocturnal species to grow in aquaculture cages indicates strong adaptability. Other wild species harvested from the cage at the same time were Oblada melanura, Scomber japonicus, Liza ramada, Diplodus vulgaris, Alosa fallax nilotica, Siganus rivulatus, Trachurus mediterranus, Lichia amia, Argyrosomus regius, Spicara smaris, Coryphaena hippurus. The proportional increase of wild species in aquaculture fish cages may cause economic losses for the companies in the future.

En la presente investigación como objetivo complejo buscamos deconstruir la lengua escrita para la producción de textos académicos-científicos reconstruyendo en estrategias complejas. A través de la escritura rizomática, discutimos la decolonización de la producción académico-científica del tradicionalismo por medio de la transmetodología compleja. El artículo se presenta en cuatro rizomas en que se discute la desconstrución rizomática, la transmetodología como un avance sobre el tradicionalismo de la ciencia, las estratégias de escritura compleja y los aportes de los rizomas para la producción academica-científica como médio de comprender mejor la complejidad de las cuestiones.
The myth of half right reference
Authors: Dudak Leah
Published: August 2022

It has been said and re-said that reference librarians only answer roughly 50% of referencequestions correctly. But while this statistic is passed around as fact - where does it come from? Inthis paper, I track down the elusive citation using backwards chaining, citation analysis, andhistorical tracing. And then, I will re-examine the study that appeared to start it all through amodern lens, ultimately suggesting that we abandon the idea of half right reference once and forall.

Published: August 2022

Many knowledge organization researchers and cultural heritage practitioners authors have illustrated the fallacies, inconsistencies, failures, mistakes, and incorrect information contained in the Library of Congress Subject Headings (LCSH). However, LCSH and its associated apparatus continues to be the dominant knowledge organization system in academic libraries (and increasingly, archives). This panel brings together individuals involved in a pair of connected projects aimed at documenting the harm and/or inaccuracies caused by LCSH by engaging in “ethical outreach” to creators and authors; by developing alternative “radical” or “critical” practices; and by evaluating the results of those practices.

Published: August 2022

Ethnography has become a popular research design in LIS, with many creative implementations as well as concomitant problems. The seven panelists have expert perspectives to share about ethnography’s evolution and impact within our field. The panel begins with a succinct overall history of the method in LIS and a critical analysis of Chatman’s methodological innovations. Then, six inventive extensions are reported: sensory ethnography; visual ethnography; ethnography within an arts-informed paradigm; ethnography within a contemplative paradigm;  critically-oriented participatory narratology and autoethnography intersections; and ethnography applied within information institutions. The presentations will systematically display ethnography’s wide-ranging colors and flavors, followed by in-depth discussion of its merits, complications, and future trajectories in LIS.
