IFRS adoption and the impact on foreign direct investment – evidence from Central and Eastern European countries
Authors: Tudor Liviu-Alexandru
Published: August 2022

The adoption of International Financial Reporting Standards (IFRS) is supposed to improve transparency by increasing the quality and the comparability of financial information. Qualitative financial information plays an important role in describing the position of a company and its financial performance, which are relevant to the investors in the decision-making process. At European level, the appearance of Regulation no.1606/2002 stimulated the implementation process by requiring to each listed company from European capital markets to prepare consolidated financial statements in accordance with IFRS for each fiscal year beginning with 1st January 2005. The main purpose of this research is to investigate the link between foreign direct investment (FDI) in 4 countries from Central and Eastern Europe and the IFRS adoption. The FDI inflows are a key factor in the economic development of a country due to their long term commitment in the business of the host country. In the present study, net inflows of FDI were analyzed in the period of 1990-2020 based on the data collected from the World Bank website. Even if we cannot draw a direct line between IFRS implementation and the increase of FDI, we cannot fail to notice that in the years when there have been changes in the legislation on convergence to IFRS there have been significant increases in the attracted FDI.
The Implementation of the International Financial Reporting Standard (IFRS 16 - “Leases”) by companies listed on the Bucharest Stock Exchange
Authors: Vrejoiu Alexandru
Published: August 2022

In accordance with the provisions of the International Financial Reporting Standard IFRS 16 “Leases”, as of January 1, 2019, insurance and reinsurance companies, non-bank financial institutions, credit institutions, brokerage companies, but also companies listed on the Bucharest Stock

Exchanges which have the quality of both tenants and lessors, must present in the annual reports relevant information regarding the transactions within the leasing contracts.

The study pursued two objectives, the identification of information on the application of IFRS 16 published in the annual reports issued in the period 2020-2021, by 30 non-financial entities out of a total of 62 listed at the date of the study at BVB, and the evaluation of how leases were reported and their impact on the financial statements.

Regarding the publication of information on the application of IFRS 16, it turned out that it was heterogeneous, in various forms. Thus, only three companies published information on leases both as lessor and lessees in both reporting years (10% of the total), 14 companies specified in both reporting years about the application of the standard only as tenants (47% of the total), nine specified about the application of the standard as tenants only in the 2019 annual report (30% of the total), and four did not specify any information on its application in none of the reporting years (13% of the total).

In terms of reporting the impacting figures the expenses determined by the leasing contracts on the financial statements, seven companies presented with data and figures from the tenant position in both years (23%), 10 only for 2019 (33% ), only two for 2020 (7%), and 11 did not present any figures (37%).
A Framework for Assessing the Readiness and Vulnerability of the Romanian Territories Affected by the Just Transition Process
Authors: Murafa Corina
Published: August 2022

The paper consists of an exploratory study which seeks to build a multi-criteria index to assess the vulnerability and the readiness of regions affected by the energy transition, based on data collected from six Romanian affected regions (Dolj, Gorj, Hunedoara, Mureș, Galați and Prahova). Literature points out both the distributional and the procedural dimension of the just energy transition process, emphasizing that the current energy transition process is distinct from previous ones due to the complex actors constellation and to the policy planning behind it. The current research is a first attempt to use various socio-economic and demographic indicators towards developing composite indexes that allow for a better understanding of the just transition processes across Europe, testing enablers and disablers of a successful transition process. The exploratory study examines two premises: that coal regions are more vulnerable than emissionsintensive regions which are not relying on coal and that the readiness of regions to embark on a transition process is directly proportional to their average GDP/ capita. I use several indicators as proxies to assess the vulnerability level (unemployment, GDP/ capita, the average monthly salary, the technological intensity of the local economies, the share of the workforce employed in industry) and others to assess the readiness level (the share of employees in transition-affected large enterprises in the total share of employees, the level of interest and engagement of local stakeholders, EU funds absorption capacity at local level). Data analysis shows surprisingly high variance of the same indicator between affected regions and unexpected correlations, such as a negative correlation between regional wealth and local authorities’ capacity to attract EU funds. It also underlines the need for a larger number of cases and more indicators in the index, to make the results statistically significant and to compensate for the high variance among indicators.
Prerequisites of a blockchain-oriented technique to assure a digital management of products recall caused by notified issues in food industry
Authors: Cornea Andreea-Alina
Published: August 2022

Today’s life is carried out under the technology umbrella and this is reflected in every aspect of daily activities, from conversations with friends, preparing meals, shopping to professional experiences. As technology advances and white-collar interests move more and more under its auspices, some of the essentials remain stuck in the routine, being slowed down by the simple fact that they are marked by certain unrevised procedures. So, in order to allow evolution in all aspects of life, the idea of identifying solutions, analyzing technological innovations and balancing the impact of digitalization in each area delayed by outdated principles is emerging. Blockchain-based solutions proved effective in a large spectrum of social and economic fields, providing ingenious approaches for up to date stringent issues. One particular area where blockchain can facilitate a significant improvement is represented by product recall. Within a global economy with supply chains extended over multiple continents, a digitalized shopping environment where customers use dedicated applications for scanning client codes and receiving electronic receipts could eliminate dead times between the moment of identifying risky products that have been for sale and the moment of warning customers to act accordingly. But before being able to benefit from a fully integrated blockchain solution for commerce, the first steps are to redirect activities towards automation and digitization by preparing the necessary prerequisites and initiating actions to change the consumer’s perception of essential activities technologicalization, as the conducted study reflects the idea that, although many people are oriented towards change, some seem reluctant.
European Union Funding-an element for predictable business success?
Authors: Olteţeanu Angel-Cristian
Published: August 2022

The aim of this paper is to discuss the ability in assessing successful investment when done by actors outside of the business arena such as government bodies or international economic cooperation agencies. More specifically, the paper aims to analyze how non-reimbursable European funding for enterprises can affect the financial results, comparing companies that have received funding through the Start-up Nation project with companies that have not received it.

In order to determine if companies receiving aid or not receiving aid can be argued to be performing better economically, I have studied data from the Start-up Nation Romania project, which provide the possibility of a concrete comparison by identifying the companies participating in the project, and analyzing which group performed better.

Published: August 2022

Objetivo: explorar aportaciones de algunas teorías de la filosofía política que son relevantes para el estudio de la desigualdad. El análisis se centra en la desigualdad económica porque es una de las formas más comunes de analizar la desigualdad; sin embargo, se exponen diversas razones para transitar al estudio multidimensional de la desigualdad. Perspectiva analítica: para abordar el tema, el texto se organiza en dos secciones principales. En la primera se indaga sobre la importancia de la desigualdad material a partir de describir sus características principales y de la revisión de datos estadísticos. En la segunda parte se reconstruyen cuatro aportaciones de la filosofía política que son relevantes para el estudio de la desigualdad, éstas son:(1) reflexiones sobre justicia y los principios políticos que guían la distribución de bienes; (2) ideologías que acompañan a la desigualdad; (3) estrategias para mitigar la desigualdad material y, por último, (4) la importancia de transitar a un análisis multidimensional de la desigualdad. Conclusión: este ensayo concluye resaltando de qué manera la filosofía política contribuye a abordar con mayor profundidad el estudio de la desigualdad en sus múltiples dimensiones; sin embargo, se concluye que estas contribuciones son a menudo omitidas en los análisis convencionales sobre el tema.
Formación estética de pies a cabeza
Authors: López de la Roche Maritza
Published: August 2022

Este libro invita a la formación estética, como un elemento clave para la infancia y la adolescencia, asociándola a la vida cotidiana y a las artes. Se fundamenta en los filósofos John Dewey, Katya Mandoki, Alain Kerlan y otros investigadores. Explora de qué modos trabajan hoy los artistas con no artistas, dentro del transformado campo artístico contemporáneo. Interroga sobre el potencial político de las artes en nuestras sociedades latinoamericanas. Tomando en cuenta qué se necesita para lograr la “ciudadanía cultural”, en una democracia que no sea ilusoria. Las artes se analizan en sus relaciones con las TIC y los medios de comunicación. Pues estas innovaciones están produciendo hoy enormes cambios en las experiencias de la sensibilidad. Se presentan dos proyectos pedagógicos con las artes: el primero desarrollado en un colegio estatal francés en Montpellier y el otro, en una institución educativa de Cali. La propuesta es introducir la formación estética y las artes en las escuelas y colegios públicos, para promover el desarrollo humano y cumplir los derechos culturales. Se exponen problemas conceptuales y propósitos prácticos. Advirtiendo que, para la construcción de iniciativas concretas, “lo teórico” no equivale solo a postulados, sino también a modos de trabajar que nos orienten a mejorar la calidad de vida de los grupos sociales de menores ingresos. Necesitamos hacer visibles las artes en la esfera pública y provocar decisiones educativas requeridas con urgencia.
The potential of Jakarta-Surabaya high-speed rail in developing tourism: Learning from Japan
Authors: Bangun Cendera Rizky Anugrah , Pratiwi Dian Fitriana , Dewi Helga Liliani Cakra
Published: August 2022

The Shinkansen is the fastest bullet train in Japan. Shinkansen greatly improve the tourism economy in some cities in Japan. Shinkansen is extremely handy for foreign visitors and reduces the cost of visiting numerous places in Japan. As is known, MRT in Jakarta is one of the collaborative projects between Japan and Indonesia. Indonesia also has a 'semi-fast' train that travels between Jakarta and Surabaya at 140-145 km/hour. Learning from the Shinkansen in Japan, the Indonesian Semi-High-Speed Train also has the potential to increase the tourism sites in Indonesia with the help of a 'push and pull strategy.' This case study used interviews and literature reviews for data collection. In this study, after data was collected, it was used to analyse the mode of transportation for tourism destinations and the marketing strategy that can be used for this research. The result of this study is that Indonesia can also imitate the implementation of tour packages from Japan's railway and tourism system. Shinkansen connects tourist destinations in various cities (intercity), and it is hoped that the semi-fast train built by the Indonesian government can do the same thing. Railways as tourism transport are only one thing in developing tourist destinations. The other thing is, of course, related to integrated tourism planning

Published: August 2022

The biographical film, Zero to Hero, shows the true story of Hong Kong sprinter So Wa Wai who won the 1996-2008 Paralympic Olympics. This study aims to identify signs to build meaning based on speech (words), images, images and sounds, words and gestures/body language, images and gestures/body language, images and objects, and words and objects. Identification of the mother's role in controlling the balance of the dimensions of cohesion, and flexibility through the application of effective communication with family members and the community is illustrated in this study. Dimensions of cohesion and flexibility that is based on Olson's Circumplex model describing family functions. Parenting interactions through the communication dimension of the mother figure play an important role in the Circumplex model. The analytical method used is Umberto Eco's semiotics which relies on the constructivism paradigm. The results showed that the Zero to Hero film contains three meaningful signs based on Olson's Circumplex model, namely signs in the form of speech, speech and body language, and speech and objects.

Published: August 2022

Mental or psychiatric disorders are problems experienced by some people. There are several types of mental disorders, such as anxiety, mood, or eating disorders. This problem affects how sufferers think and behave, like obsessive-compulsive disorder (OCD). A mental disorder makes sufferers have thoughts and behaviours that are not controlled (obsessions) to do something repeatedly (compulsively). The action can also interfere with the sufferers' daily activities and social interactions. This study aimed to determine therapeutic communication in survivors of obsessive-compulsive disorder (OCD). The method used in this research is phenomenology, where the informants in this study are survivors of obsessive-compulsive disorder (OCD). The conclusion of this study shows that therapists engage in therapeutic communication with Obsessive-Compulsive Disorder (OCD) survivors using a form of psychological therapy that helps OCD survivors overcome their worries and obsessive thoughts without coercion. This is done by raising the ability to pay attention, empathy, and the ability to respond.

Published: August 2022

This study explored the occurrence of a free e-book titled Speed Reading for Beginners that can only be obtained by signing up for an email newsletter at MembacaCepat.com. Through Web 2.0, the Internet facilitated the emergence of a new culture centred on shifting consumer relationships in which individuals both consumed and produced the products they consumed. The purpose of this study is to carry out further research into the communication pattern regarding how the practices of production and consumption, also known as prosumption, occurred at the same agency via the web manager or web owner and e-book downloaders. This study employs virtual ethnography by interviewing informants and observing artefacts as data via the Internet. This study aims to utilise the circuit of culture as an analytic framework, similar to the consumption circuit outlined in continuing consumption practices. The findings indicate that the pattern of production and consumption can be mapped as a collaborative effort between website owners and visitors, with the Speed Reading for Beginners e-book catalysing increased visitor participation.
News of LGBT on online media in 2020: endless stigma
Authors: Listiorini Dina , Vidiadari Irene Santika
Published: August 2022

Mass media and its content on various platforms play a significant role in shaping knowledge in society, including the knowledge about sexuality. This article discusses news on LGBT on four Indonesian online media—Viva.co.id, Republika.co.id, Tempo.co.id, and Detik.com—by conducting quantitative content analysis. The result shows that the news on LGBT in 2020 centred on three main issues: the ban on gay individuals joining the army/police, the male rape case committed by Reynhard Sinaga, and male same-sex sexual intercourse in Wisma Atlet. The news structure on LGBT does not pay attention to the information depth, as indicated by the lack of paragraph numbers in the news and the lack of 5W+1H construction. In addition, the coverage is often one-sided, making it unbalanced. Eventually, the construct about LGBT becomes biased.
Understanding intention to use communication technology among legislators: a UTAUT model perspective
Authors: Hafiar Hanny , Sjoraida Diah Fatma , Amin Kholidil
Published: August 2022

During the Covid-19 pandemic, face-to-face meetings are restricted; therefore, communication technology such as video conferencing apps is essential for workers, including legislators. Using the Unified Theory of Acceptance and Use of Technology (UTAUT), this study examines technology acceptance factors on the intention to use video conferencing apps by legislators of the West Java Provincial House of Representatives during the COVID-19 pandemic. The respondents of this study were 92 legislators who were chosen randomly. The results showed that the technology acceptance factors were associated with the intention, even simultaneously predicting the intention to use video conferencing apps. There are theoretical and practical implications discussed in the findings of this study. The present study strengthens that the technology acceptance factor in the UTAUT model can explain the mechanism for the emergence of individual intentions. It is necessary to have good social influence and environmental conditions to facilitate individuals in raising behavioural intention to use communication technology.

Authors: Carvajal-Escobar Mario David Fernando , Sepúlveda-Gallego Luz Elena , Gómez-Londoño Carlos Fernando
Published: August 2022

Introducción. La osteosíntesis con clavos elásticos (fijación intramedular) es un procedimiento que  ha venido ganando reconocimiento como una alternativa mínimamente invasiva para el manejo de las fracturas diafisiarias de clavícula (AO/OTA15.2A). Sin embargo, debido a su perfil de complicaciones, la elección del método más adecuado para el manejo primario de las fracturas desplazadas todavía es motivo de controversia. Objetivo. Comparar las tasas de consolidación; los resultados anatómicos, funcionales y estéticos, y las complicaciones en pacientes con fracturas desplazadas del tercio medio de la clavícula intervenidos con clavos elásticos o con placas. Materiales y métodos. Estudio comparativo retrospectivo realizado en 99 pacientes con fracturas desplazadas del tercio medio de la clavicula. Se registraron variables demográficas, tiempo quirúrgico, estancia  hospitalaria, complicaciones postoperatorias, longitud de la cicatriz, grado de satisfacción y alteraciones en la sensibilidad de la piel. El resultado funcional se calculó mediante los puntajes Constant y Quick-DASH. Resultados. Se analizaron los resultados de 61 osteosíntesis con clavos elásticos y 38 con placa. En los pacientes intervenidos con clavos elásticos el tiempo de cirugía y el tamaño de la cicatriz fueron menores, mientras que el puntaje Constant, los síntomas irritativos y la prominencia del material fueron mayores. Por su parte, en los pacientes intervenidos con placas la tasa de pseudoartrosis, las alteraciones en la consolidación y la disestesia en la cicatriz fueron mayores. Conclusión. La fijación intramedular para fracturas del tercio medio de la clavícula es una alternativa menos invasiva, con mejores resultados estéticos y funcionales, y con menos complicaciones mayores, en comparacion con la fijación con placa

Authors: Gusmão Filho Niceas da Silva , Kaempf de Oliveira Ricardo , Trindade Rios Givaldo , Queirós de Sousa Gudson Gleyton
Published: August 2022

Introduction: The scapholunate ligament (SLL) injury can cause wrist pain and instability. There is a wide variety of surgical techniques used for the treatment of this lesion, such as dorsal capsulodeses, tenodeses with flexor or extensor tendons, and bone-ligament-bone graft.

Objective: To describe a new technique for the treatment of SLL injury aiming to stabilize the dissociated carpus with a double dorsal capsulodesis.

Materials and methods: By presenting the case of a 36-year-old male security officer who injured his left wrist in a motorcycle accident, a procedure to align the carpus is proposed. The long-term outcome of this procedure is also described

Results: The proposed surgery was successfully performed; it had excellent clinical and functional results, with no complications. Long-term restoration of carpal alignment observed in wrist radiographs was evidenced after two years of follow-up, the patient was asymptomatic and with full functional recovery.

Conclusion: The proposed technique appears to be reproducible, effective and easy to perform. Unlike the technique described by Blatt, the aim of this one is to restore the physiological position of the lunate bone by adding a second capsulodesis, as it is believed to be an essential factor in the maintenance of carpal kinematics.
Lipoma supraclavicular izquierdo asociado con los troncos del plexo braquial. Reporte de caso
Authors: Gallego-Gónima Sabrina , Jiménez-Cotes Evert Armando
Published: August 2022

Introducción. Los lipomas son los tumores de tejidos blandos más comunes; sin embargo, su localización en el plexo braquial es extremadamente rara. Estos se pueden manifestar por síntomas compresivos insidiosos debido a que envuelven las estructuras nerviosas y su tratamiento en la mayoría de casos es la resección quirúrgica.

Presentación del caso. Mujer de 56 años con edema progresivo del miembro superior izquierdo, parestesias episódicas y sensación de peso de dos años de evolución, en quien, mediante resonancia magnética, se documentó la presencia de una masa encapsulada de 6 x 8 cm localizada en los troncos y divisiones del plexo braquial izquierdo en íntimo contacto con los vasos subclavios. La paciente fue diagnosticada con lipoma en el plexo branquial e intervenida mediante abordaje quirúrgico abierto supraclavicular izquierdo extendido al surco deltopectoral y disección infraclavicular bajo magnificación, con lo cual se logró la resección completa de la lesión sin compromiso de las estructuras nerviosas.

Conclusión. Los lipomas ubicados en los troncos del plexo braquial son entidades benignas raras y de crecimiento progresivo que pueden causar síntomas compresivos sensitivos y motores. El tratamiento quirúrgico es una opción terapéutica segura cuando es realizado por personal entrenado, pues el riesgo de lesionar estructuras nerviosas durante la resección quirúrgica de la masa es alto.

Authors: Cayón-Cayón Fidel , Alegría-Velasco Gabriel , Ramírez-Navarrete María
Published: August 2022

Las manos son órganos especialmente vulnerables a lesiones traumáticas, siendo los dedos la zona lesionada con mayor frecuencia, especialmente en el campo laboral; lo anterior conlleva graves complicaciones y consecuencias tanto para el paciente por las limitaciones que ocasiona, como para el sistema de salud por los gastos que genera. Existen varias técnicas para el manejo de lesiones severas en los dedos, pero todas buscan mantener su longitud y funcionalidad. De esta forma, la transferencia pediculada de falange distal hacia la posición de falange media es una alternativa para la creación de un dedo de dos falanges.

En el presente estudio se presenta la experiencia clínica y quirúrgica de los autores con el uso de esta técnica en el manejo de lesiones severas sobre la falange media; esta es una técnica que se diseñó con el objetivo de mantener la mayor cantidad de tejido viable posible y una alta funcionalidad de la mano.

Con la técnica descrita se observan resultados funcionales y estéticos buenos a corto y mediano plazo, por lo que puede considerarse como una opción válida para el tratamiento de lesiones de las falanges en las que el extremo distal es aún viable.

Published: August 2022

Objetivo: Descrever a técnica de toracotomia de reanimação, suas indicações e reunir informações de estudos sobre sua realização, para fornecer dados baseados em evidências e auxiliar os cirurgiões gerais e médicos de pronto-socorro em sua tomada de decisão sobre o uso dessa técnica. Revisão bibliográfica: Os resultados demonstraram que a toracotomia de reanimação é útil para salvar vidas, mas é concebível apenas para pacientes que sofrem de trauma grave (especialmente os penetrantes) com parada cardíaca in extremis. Por esse tipo de trauma ser uma situação extrema de emergência, necessitando de um procedimento que precisa ser realizado de imediato, a toracotomia de reanimação comumente é realizada fora do centro cirúrgico, e nem sempre há um cirurgião geral disponível na emergência. Considerações finais: Assim, esse estudo alerta para que hospitais que recebem pacientes de emergência após um trauma realize treinamento e capacitação de seus profissionais para receber esses pacientes, visto que podem necessitar de uma toracotomia de reanimação, que pode ser a diferença entre a vida e a morte para esses pacientes.
Enhancing Sampling of Water Rehydration upon Ligand Binding using Variants of Grand Canonical Monte Carlo
Authors: Ge Yunhui , Melling Oliver , Dong Weiming , Essex Jonathan , Mobley David
Published: August 2022

Water plays an important role in mediating protein-ligand interactions. Water rearrangement upon a ligand binding or modification can be very slow and beyond typical timescales used in molecular dynamics (MD) simulations. Thus, inadequate sampling of slow water motions in MD simulations often impairs the accuracy of the accuracy of ligand binding free energy calculations. Previous studies suggest grand canonical Monte Carlo (GCMC) outperforms normal MD simulations for water sampling, thus GCMC has been applied to help improve the accuracy of ligand binding free energy calculations. However, in prior work we observed protein and/or ligand motions impaired how well GCMC performs at water rehydration, suggesting more work is needed to improve this method to handle water sampling. In this work, we applied GCMC in 21 protein-ligand systems to assess the performance of GCMC for rehydrating buried water sites. While our results show that GCMC can rapidly rehydrate all selected water sites for most systems, it fails in 5 systems. In most failed systems, we observe protein/ligand motions, which occur in the absence of water, combine to close water sites and block instantaneous GCMC water insertion moves. For these 5 failed systems, we both extended our GCMC simulations and tested a new technique named grand canonical nonequilibrium candidate Monte Carlo (GCNCMC). GCNCMC combines GCMC with the nonequilibrium candidate Monte Carlo (NCMC) sampling technique to improve the probability of a successful water insertion/deletion. Our results show that GCNCMC and extended GCMC can rehydrate all target water sites for three of the five problematic systems and GCNCMC is more efficient than GCMC in two out of the three systems. In one system, only GCNCMC can rehydrate all target water sites, while GCMC fails. Both GCNCMC and GCMC fail in one system. This work suggests this new GCNCMC method is promising for water rehydration especially when protein/ligand motions may block water insertion/removal.
Pre-Synthetic Redox Gated Metal-to-Insulator Transition and Photothermoelec-tric Properties in Nickel Tetrathiafulvalene-Tetrathiolate Coordination Polymers

Published: August 2022

Photothermoelectric (PTE) materials are promising candidates for solar energy harvesting and photodetection applications, especially for near-infrared (NIR) wavelengths. Although the processability and tunability of organic materials is highly advantageous, examples of organic PTE materials are comparatively rare and their PTE performance is typically limited by poor photothermal (PT) conversion. Here we report the use of redox-active Sn complexes of tetrathiafulvalene-tetrathiolate (TTFtt) as transmetalating agents for the synthesis of pre-synthetically redox tuned NiTTFtt materials. Unlike the neutral material NiTTFtt, which exhibits n-type glassy-metallic conductivity, the reduced materials Li1.2Ni0.4[NiTTFtt] and [Li(THF)1.5]1.2Ni0.4[NiTTFtt] (THF = tetrahydrofuran) display physical characteristics more consistent with p-type semi-conductors. The broad spectral absorption and electrically conducting nature of these TTFtt-based materials enable highly efficient NIR-thermal conversion and good PTE performance. Furthermore, in contrast to conventional PTE composites, these NiTTFtt coordination polymers are nota-ble as single-component PTE materials. The pre-synthetically tuned metal-to-insulator transition in these NiTTFtt systems directly modulates to their PT and PTE properties.
A toy model of a catalytic filter in series with a gas sensor
Authors: Fabusola Gbenga , Noh Gina , Simon Cory
Published: August 2022

The cross-sensitivity of a gas sensor can be mitigated by installing a catalytic filter upstream. The objective of the filter is to convert interferents into species that interact weakly with the recognition element of the sensor. Mathematical models may be useful for optimizing the design parameters of the catalytic filter. Particularly, if the catalyst is not perfectly selective for the interferent over the analyte, we hypothesize the existence of an optimal residence time of the gas in the filter. Short residence times allow too much interferent to reach the sensor and corrupt its response, while long residence times degrade too much of the analyte, diminishing the signal-to-noise ratio. Herein, we develop a toy mathematical and probabilistic model of a catalytic filter and gas sensor in series. We model (a) the catalytic filter as an isothermal, packed-bed reactor that decomposes the interferent and analyte with first-order kinetics and reactant-selectivity for the interferent and (b) the cross-sensitive gas sensor as gravimetric, producing a response with contributions from the analyte and interferent, governed by the competitive Langmuir adsorption model. Under distributions of (a) concentrations of interferent and analyte in the sensing environment and (b) measurement noise corrupting the response of the sensor, we simulate deployment of the model catalytic filter-gas sensor, where the objective is to accurately predict the concentration of the analyte in the gas phase from the response of the sensor. The performance of the catalytic filter-gas sensor is measured by the expected error in the predicted concentration of the analyte. Indeed, our toy model shows an optimal residence time of gas in the catalytic filter, which depends on the reactant-selectivity of the catalyst. While just a caricature of a catalytic filter-gas sensor, our toy model illustrates the utility of mathematical and probabilistic models for optimizing their design parameters.

Published: August 2022

A ten-step bio-inspired enantioselective synthesis of peshawaraquinone, an uncommon and complex naphthoquinone mero-terpenoid is described. Key to the success of this synthetic pathway is a well-tuned HFIP-promoted metal-free allylation was developed to coupling lawsone with allylic alcohols, together with an usual organo-catalyzed [3+2] cycloaddition for con-structing the bicyclo[3.2.1]octane core structure. Further investigation disclosed peshawaraquione is a racemic mixture.

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.

Buffer solutions have tremendous importance in biological systems and in formulated products. Whilst the pH response upon acid/base addition to a mixture containing a single buffer can be described by the Henderson-Hasselbalch equation, modelling the pH response for multi-buffered poly-protic systems after acid/base addition, a common task in all chemical laboratories and many industrial plants, is a challenge. Combining predictive modelling and experimental pH adjustment, we present an active machine learning (ML)-driven closed-loop optimization strategy for automating small scale batch pH adjustment relevant for complex samples (e.g., formulated products in the chemical industry). Several ML models were compared on a generated dataset of binary-buffered poly-protic systems and it was found that Gaussian processes (GP) served as the best performing models. Moreover, the implementation of transfer learning into the optimization protocol proved to be a successful strategy in making the process even more efficient. Finally, practical usability of the developed algorithm was demonstrated experimentally with a liquid handling robot where the pH of different buffered systems was adjusted, offering a versatile and efficient strategy for a pH adjustment processes.
Social Media and Mental Health

There are seemingly opposing findings on social media’s effect on mental well-being. Some studies report no detrimental effects, others no association and others even positive or buffering effects. However, social media has rapidly evolved in a short span of time and so has people’s use of the platforms. Collecting an accurate measure of social media use and other methodological challenges particularly affect data in this area. In this commentary, we discuss two longitudinal studies to elaborate these contracting findings on social media and mental health.
Sonoist: An Innovative Peer Ultrasound Learning Initiative on Canadian Teaching Hospital Wards
Authors: Yan Laura , Niburski Kacper , Snell Linda
Published: August 2022

Background: Students usually learn point-of-care ultrasound (PoCUS) on standardized patients, thus lacking opportunities to correlate their ultrasound findings with clinical abnormalities. Sonoist is a student-led initiative aimed at improving ultrasound training with peer-teaching and real patients. We describe here a pilot project of Sonoist, its implementation and evaluation.

Methods: Sonoist was developed by Independent-Practitioner-certified medical students who teach their peers how to scan patients with abnormal clinical findings, then correlating their ultrasound findings with the physical examination. From May 2019 to February 2020, seven sessions were held, with a sessional average of 3 participants and 3 patients scanned. We collected survey data on ultrasound knowledge, participants’ perceived self-improvement, and general comments. Results were grouped by prior ultrasound training (novice n=8, experienced n=12) and year of study (1-4).

Results: 20/23 completed the survey. An increase in ultrasound skill was perceived by 100% of novices and 66.7% of experienced learners. Knowledge about clinical indications for PoCUS improved in 80% of novice and 81% of experienced students; sonographic knowledge improved in 69% of novices and 81.3% of experienced learners. All novices and 91.7% of experienced learners reported that learning ultrasound was useful for correlating with physical exam and clinical diagnosis. All novices and 83% of experienced students preferred peer-to-peer teaching.

Conclusion: Peer-to-peer PoCUS teaching improved medical students’ sonographic and clinical knowledge, and is perceived as useful by students. A combination of early clinical exposure and a less stressful environment from peer teaching may contribute to these results.

Authors: Elmi Parham
Published: August 2022

COVID-19 has impacted the lives of many Canadians physically, emotionally, and financially. This commentary focuses on suggestions on how to use social media platforms to target Canadians to promote public COVID-19 related health messaging. Policy strategies that limit the use of algorithms for social media in an effort to eliminate opinion silos and provide users with a more well-rounded view of current events are explored.
Approach to Strabismus
Authors: Dhoot Arjan , Wan Michael
Published: August 2022

Strabismus is characterized by a misalignment of the eyes.  A thorough history and physical examination should be performed by clinicians when strabismus is suspected. The Hirschberg, cover, cover-uncover, and alternate prism cover tests are commonly used to identify and diagnose strabismus. Strabismus usually requires a referral to an ophthalmologist. Treatment of strabismus involves eye patches, cycloplegic drops, prescription glasses, and surgery. Strabismus can result in vision loss due to amblyopia and may also cause double vision, psychosocial concerns, and impaired depth perception.
Participación de los esquemas desadaptativos en la violencia de pareja y el bienestar psicológico: Una revisión descriptiva de la literatura

Published: August 2022

El presente estudio tuvo como objetivo analizar la literatura disponible sobre los esquemas desadaptativos en la violencia de pareja y el bienestar psicológico, desde la revisión descriptiva de la literatura; para ello se realizó una búsqueda en EBSCOhost, Scielo, Scopus, ProQuest y Science Direct, considerando los términos de búsqueda “esquemas”, “violencia”, “bienestar psicológico” y “salud mental. Se revisaron más de 20 trabajos a texto completo, de los que fueron seleccionados 16 artículos académicos publicados en castellano, portugués o inglés entre los años 2015 y 2021; los resultados evidencian que las personas con esquemas desadaptativos poseen patrones que comprometen sus recuerdos, sensaciones corporales, emociones y cogniciones acerca de sí mismas y de sus relaciones con otras. Así mismo los síntomas de depresión se asociaron con el dominio de desconexión y rechazo; que también se asocia como predictor de violencia; autonomía y el rendimiento, estos tres esquemas asociados con síntomas psicopatológicos; se concluye que los esquemas desadaptativos están relacionados con experiencias perjudiciales en la niñez. Se necesitan medidas de intervención y prevención tempranas, especialmente para aquellas personas que sufrieron violencia en sus hogares priorizando el bienestar psicológico y no se convierta en un factor de riesgo.
