Repeated Psychosocial Screening of High School Students Using YouthCHAT: Cohort Study (Preprint)
Authors: Thabrew Hiran , Kumar Harshali , Goldfinch Mary , Cavadino Alana , Goodyear-Smith Felicity
Published: June 2020

BACKGROUND

Psychosocial problems are common during adolescence and can have long-lasting effects on health and on academic and social functioning. YouthCHAT, an electronic HEEADSSS (home, education, eating, activities, drugs and alcohol, suicide and depression, sexuality and safety)-aligned instrument, has recently been demonstrated to be an acceptable and effective school-based psychosocial screener for 13-year-old (Year 9) high school students.

OBJECTIVE

This study aims to compare acceptability and detection rates with repeated YouthCHAT screenings of high school students when they are 13 years old (Year 9) and 14 years old (Year 10).

METHODS

We invited all Year-10 students to complete a YouthCHAT screening in 2018. Rates of positively identified issues were compared between the subset of students screened in both 2017 and 2018. Student acceptability toward YouthCHAT was investigated through focus group sessions. Onward clinical referral rates in 2018 were also investigated to explore the potential referral burden following screening. Data analysis for rates of positively identified issues were conducted with the McNemar test. Chi-square, Fisher exact test, and Kruskal-Wallis test were used to analyze the focus group data.

RESULTS

Of 141 eligible Year-10 students, 114 (81%) completed a YouthCHAT screening during 2018, and 97 (85%) of them completed it for a second time. Apart from depression, which increased (P=.002), and perceived life stress, which decreased (P=.04), rates of identified issues were broadly similar between 13 and 14 years of age. Repeated screenings via YouthCHAT was acceptable to students and time-efficient (mean, 6 minutes and 32 seconds) but did not reduce the overall number of individuals with identified issues. Onward clinical referrals from positive screens were mostly managed by school-based health services without the need for external referrals.

CONCLUSIONS

Although further evaluation is needed, our results support the value of YouthCHAT as an acceptable and effective instrument with which to achieve routine identification of psychosocial issues and early intervention within a high school environment.
Understanding Spatial Heterogeneity of COVID-19 Pandemic Using Shape Analysis of Growth Rate Curves (Preprint)
Authors: Srivastava Anuj , Chowell Gerardo
Published: June 2020

UNSTRUCTURED

The growth rates of COVID-19 across different geographical regions (e.g., states in a nation, countries in a continent) follow different shapes and patterns. The overall summaries at coarser spatial scales that are obtained by simply
averaging individual curves (across regions) obscure nuanced variability and blurs the spatial heterogeneity at finer spatial scales. We employ statistical methods to analyze shapes of local COVID-19 growth rate curves and statistically group them into distinct clusters, according to their shapes. Using this information, we derive the so-called elastic averages of curves within these clusters, which correspond to the dominant incidence patterns. We apply this methodology to the analysis of the daily incidence trajectory of the COVID-pandemic at two spatial scales: A state-level analysis within the USA and a country-level analysis within Europe during mid-February to mid-May, 2020. Our analyses reveal a few dominant incidence trajectories that characterize transmission dynamics across states in the USA and across countries in Europe.
This approach results in broad classifications of spatial areas into different trajectories and adds to the methodological toolkit for guiding public health decision making at different spatial scales.

Authors: Hutchings Owen Rhys , Dearing Cassandra , Jagers Dianna , Shaw Miranda Jane , Raffan Freya , Jones Aaron , Taggart Richard , Sinclair Tim , Anderson Teresa , Ritchie Angus Graham
Published: June 2020

BACKGROUND

Australia has successfully controlled the COVID-19 pandemic. Similar to other high-income countries, Australia has extensively used telehealth services. Virtual health care, including telemedicine in combination with remote patient monitoring, has been implemented in certain settings as part of new models of care that are aimed at managing patients with COVID-19 outside the hospital setting.

OBJECTIVE

This study aimed to describe the implementation of and early experience with virtual health care for community management of patients with COVID-19.

METHODS

This observational cohort study was conducted with patients with COVID-19 who availed of a large Australian metropolitan health service with an established virtual health care program capable of monitoring patients remotely. We included patients with COVID-19 who received the health service, could self-isolate safely, did not require immediate admission to an in-patient setting, had no major active comorbid illness, and could be managed at home or at other suitable sites. Skin temperature, pulse rate, and blood oxygen saturation were remotely monitored. The primary outcome measures were care escalation rates, including emergency department presentation, and hospital admission.

RESULTS

During March 11-29, 2020, a total of 162 of 173 (93.6%) patients with COVID-19 (median age 38 years, range 11-79 years), who were diagnosed locally, were enrolled in the virtual health care program. For 62 of 162 (38.3%) patients discharged during this period, the median length of stay was 8 (range 1-17) days. The peak of 100 prevalent patients equated to approximately 25 patients per registered nurse per shift. Patients were contacted a median of 16 (range 1-30) times during this period. Video consultations (n=1902, 66.3%) comprised most of the patient contacts, and 132 (81.5%) patients were monitored remotely. Care escalation rates were low, with an ambulance attendance rate of 3% (n=5), emergency department attendance rate of 2.5% (n=4), and hospital admission rate of 1.9% (n=3). No deaths were recorded.

CONCLUSIONS

Community-based virtual health care is safe for managing most patients with COVID-19 and can be rapidly implemented in an urban Australian setting for pandemic management. Health services implementing virtual health care should anticipate challenges associated with rapid technology deployments and provide adequate support to resolve them, including strategies to support the use of health information technologies among consumers.
fragile équilibre des intérêts locaux et nationaux dans l'interprétation de la compétence fédérale sur l'aéronautique: l'exemple du parachutisme
Authors: Robitaille David
Published: June 2020

Au cœur du régime fédéral canadien et de l’interprétation qu’en font les tribunaux, se trouve la recherche d’un équilibre entre les intérêts locaux et les intérêts nationaux. Cette tâche n’est pas aisée, mais est essentielle afi n de préserver la capacité des autorités locales à gouverner en fonction des intérêts, des préoccupations et des besoins particuliers de leurs citoyens, tout en permettant l’intervention nécessaire du Parlement sur les enjeux qui concernent le pays dans son ensemble.

La compétence fédérale sur l’aéronautique illustre clairement la complexité à tracer la ligne entre les intérêts locaux et les intérêts nationaux. Les tribunaux canadiens ont de la diffi  culté à ménager les compétences locales en ce domaine et semblent au contraire considérer l’aéronautique comme une « super » compétence, ne laissant qu’une marge de manœuvre très étroite aux autorités locales en matière d’aménagement durable et sécuritaire du territoire. Or, contrairement à ce que semblent parfois percevoir les tribunaux, ce n’est pas pour mettre arbitrairement des bâtons dans les roues des entreprises ou des activités fédérales que des municipalités refusent parfois que ces dernières s’implantent sur une portion spécifi que du territoire ou exigent le respect de normes en matière de gestion du risque. L’objectif phare étant de répondre aux préoccupations légitimes de citoyens inquiets, telles que le bruit accru, le saccage de milieux humides à grande valeur environnementale, la pollution de l’air qu’ils respirent et de l’eau qu’ils boivent, et du développement inconséquent du territoire1.

Les municipalités ne peuvent pas adopter de règlements qui régissent directement ou concernent l’aéronautique par leur caractère véritable, sans quoi ils seraient déclarés inconstitutionnels. Les règlements municipaux d’application générale qui concernent l’aménagement du territoire ainsi que l’environnement, la santé et la sécurité des citoyens peuvent toutefois s’appliquer aux activités aéronautiques. Par contre, ces règlements ne doivent pas entraver le cœur ou les aspects essentiels de cette compétence fédérale, ni être en confl it avec la réglementation fédérale.

Le plus récent arrêt de la Cour d’appel du Québec sur la question, Procureure générale du Québec c. Leclerc2, montre bien la diffi  culté qu’ont les municipalités à faire respecter leurs compétences en matière d’aéronautique. Cette aff aire, dont la Cour suprême a refusé l’autorisation de pourvoi3, mettait en cause l’applicabilité constitutionnelle du Règlement sur le zonage et le lotissement (« Règlement sur le zonage ») et du Règlement sur les permis et les certifi cats (« Règlement sur les permis ») de la Ville de Lévis à l’égard d’activités commerciales et sportives de parachutisme ayant cours en zone agricole. Seule la doctrine de l’exclusivité des compétences fut soulevée en première instance par la défenderesse, Albertine Leclerc, à l’encontre des constats d’infraction qui avaient été émis par la Ville4.
Introduction: Symbolic Politics, Constitutional Consequences*
Authors: Kate Bezanson and Alison Braley-Rattai
Published: June 2020

Free expression that leads to the vibrant exchange of ideas is thought to be the very lifeblood of a democratic society. It appears self-evident that campuses, where even the most resolute ‘truths’ not only may but even should be examined and re-examined, are the nucleus of such a society. Despite this, campus speech has become a flashpoint for competing — some would say irreconcilable — demands. On the one hand is the view that some speech should not be tolerated in an environment that must embrace diversity that is also a hallmark of our advanced liberal democracy, and which should aim for the equality of its members. Per this argument, some members of the university community are treated unequally when speech that tends to reinforce their marginalization as members of a sub-dominant group is permitted. This view may also extend to pedagogical practice, and so we might identify the debate as to whether certain words are ipso facto impermissible, regardless of their intended purpose.2

Published: June 2020

In August 2018, the Ford Government in Ontario introduced a ‘Directive’ entitled “Upholding Free Speech on Ontario’s University and College Campuses” (the Directive).1 The Directive required all publicly supported universities and colleges2 in Ontario to create a free speech policy by January 1st 2019 that applies to “faculty, students, staff, management and guests,” and includes a) a definition of free speech, and b) reference to various “principles” of free speech similar to those elucidated by the University of Chicago (Chicago Principles).3 According to the Directive, speech that is otherwise illegal is not permitted. Illegal speech includes hate speech and uttering threats that are proscribed by Canada’s Criminal Code,4 defamatory speech which can give rise to both criminal5 and civil6 actions, as well as workplace harassment.7

Oral mucosal diseases are common in routine dental practices and significantly influence patients’ quality of life. Dental students should be aware about the management of oral mucosal diseases as well as the major oral diseases such as dental caries, gingivitis and periodontitis. This study aimed to evaluate, attitudes and practices of dental students regarding management of certain oral mucosal conditions.  This is a cross sectional KAP study conducted  among dental students in Saudi Arabia. Inclusion criteria were students in 4th academic year or higher, since these students should study the pharmacological courses starting from the 4th academic year. The sample included 300 students to whom questionnaires  were distributed. Chi-square test of homogeneity  was used to detect significant differences in students’ knowledge, attitudes and practices based on students’ characteristics. The level of knowledge about the studied oral mucosal diseases was high in 62.7% of dental students, while only 2% had low level of knowledge. The attitude of the students was good in 48%, however 11.7% had poor attitude towards drug prescription of the medications for theses oral mucosal diseases. The practices of the dental students in prescription of medications during their clinical training were good in 16%, while it was poor in 31% of dental students. The knowledge regarding drug prescription for oral mucosal drugs were high  among  the  majority  of  dental  students,  however  the  prescription  practices  were  poor  when  compare  to  the  level  of knowledge.

Published: June 2020

Sodium fluoride is a trace element required for human beings to prevent early dental disorders and to meet body’s minimum Fluoride levels. It is signified as a nutritional supplement for the prevention of dental caries in children of areas with inadequate Fluoride concentration in the drinking water. When Fluoride concentration exceeds required levels in the body, it commences bacteriostatic activity against beneficial flora in the gastrointestinal tract. Two such commonly affected organisms are  L.  acidophilus  and  L.  salivarius.  These  are  probiotic  organisms  that  help  to  maintain  immunogenic  gut  against  several pathogenic organisms. In our previous study, Minimum inhibitory concentration (MIC) and growth dynamics were assessed on L. acidophilus and L. salivarius, in the presence of different Sodium fluoride concentrations. L. acidophilus and L. salivarius were observed to be inhibited at 20 mM and 40 mM Sodium fluoride concentrations respectively. These inhibitory concentrations were selected for further analysis. The proteins were isolated from such Sodium fluoride treated and untreated cells, the protein concentration was estimated by Bradford assay and protein profiling was done by 1D Gel Electrophoresis. The protein concentration is found to be higher in Sodium fluoride untreated organisms and below 3 kDa proteins of Sodium fluoride treated samples. Whereas low protein concentration was observed in the above 3 kDa protein samples (L.acidophilus treated protein sample above 3 kDa and L.salivarius treated protein sample above 3 kDa) of fluoride treated organisms.  L. acidophilus and L. salivarius showed difference in protein expression under fluoride stress. Protein expression is high in L. salivarius than L. acidophilus. This is an indication that these strains have different capabilities for adapting to varying environmental conditions. we conclude that there is no impact on below 3 kDa protein samples in Sodium fluoride treated organisms and impact was there on the above 3 Kda proteins which are inhibited.

Safinamide is a novel drug with both dopaminergic and non-dopaminergic effects, approved first by the European Commission   and   more   recently   by   the   US   Food   and   Drug   Administration   (FDA)   as   an   adjunctive treatment   to carbidopa/levodopa in patients with mid- to late-stage Parkinson’s disease (PD) and motor fluctuations. The validated analytical method was applied for the estimation of Safinamide in aqueous solution and human plasma with Safinamide-D4 as an internal standard by using UPLC-MS/MS. The chromatographic separation was achieved with 0.1% formic acid solution: Methanol, 30:70% v/v using CORTECS C18 with 100 x 4.6, 2.7 µ. The total analysis time was 4 min, and the flow rate set to 0.8 mL/min. The mass transitions of Safinamide and Safinamide-D4 obtained were m/z 303.3 and 215.2 and 307.3 and 215.2.  The standard curve shows a correlation  coefficient  (r2) greater  than 0.998 with a range of 113.0-338.0  pg/mL  using the linear regression  model. The method has shown good reproducibility, as intra- and interday precisions were within 10% and accuracies were within 8% of nominal values for both analytes. The method was successfully applied for the forced degradation studies at various stress conditions.

The western corn rootworm (Diabrotica virgifera virgifera LeConte; WCR) is
the most destructive maize pest in the USA, and one of the most dangerous
pests in Europe. In just over a decade from the introduction it became one
of the most serious pests in Croatia. Native resistant cultivars could be an
efficient strategy for WCR control. Although research in WCR host plant
resistance has continuously been conducted for over 70 years, no resistant
maize hybrid is commercially available today. The aim of this study was to
evaluate resistance traits in the maize IBM intermated recombinant inbred
lines (IRILs), and detect QTLs associated with resistance to WCR herbivory.
Total of 207 recombinant inbred lines were phenotyped for standard WCR
resistance traits. Several associated QTLs were detected on chromosomes 1,
5, 6, 8, 9, and 10. QTLs on chromosomes 1 (6.41 % variance explained), and 6
(9.26 % variance explained) were mapped in regions harboring genes connected
with plant defense against herbivory. Detected QTLs provide relevant
guidelines for future research on WCR resistance in maize.

The phenomenon of genotype by environment interaction (GEI) represents
permanent interest for breeders, geneticists and biometricians with its
practical and theoretical aspects. We investigated GEI for grain yield of
medium early maturity maize (Zea mays L.) hybrids from the official variety
trial network by the Department of Protection and Recognition of Varieties
of the Republic of Serbia that includes experimental maize hybrids on eight
sites over two years. Environmental variables explained 77.6% and 60.7% of
the GEI variation for two consecutive years, respectively. Factorial
regression combined with stepwise procedure revealed the model which
includes variables precipitation in July (pr7), minimum temperature in May
(mnt5), maximum temperature in May (mxt5) and insolation hours in April
(sh4), in 2004, and environmental index (EI) and average temperature in
September (mt9) in 2005, to be the most explanatory models in the region of
Vojvodina (Serbia) in two consecutive years. These results provide a base
for further research in GEI and stability analysis, and are a useful tool in
characterizing the sub-regions of maize growing area and extending the
existing results to new sites.

Arabic learningin the senior high school level still requires good planning to be able to carry out the process and evaluation of learning in accordance with the desired goals. Arabic learning in Indonesia is still focused on the delivery of material using traditional methods, only a few schools have developed the Arabic learning process in accordance with the demands of 21st century learning. It is appropriate that Arabic learning can internalize the values of soft skills in terms of cognitive, affective or psychomotor through attractive and innovative learning designs. This study aims to construct materials, media, method and evaluation that are in accordance with 21st century in Arabic language learning designs. This research method used a qualitative method based on text analysis. Therefore, the analysis used in reading and interpreting qualitative data is content analysis and system analysis. The results of this research recommend that Arabic learning designs for high school level suitable for the 21st century should contain; 1) must construct material by contextual material, 2) using technology and information, 3) using cooperative learning model based on HOTS in learning process, 4) evaluation using authentic assessment.Arabic learning in a holistic and integral way can answer the challenges of the 21st century. This paper discusses reformulate learning based on learning in the global era as an ideal alternative for Arabic learning.

The challenges of education in meeting millennial needs who are very familiar with technology and the internet are quite large. This is because their life experiences are different, especially their experience in using technology. The purpose of this research is to formulate a formula for evaluating Arabic speaking skills by using YouTube as an evaluation medium and seeing phenomena that emerge when Youtube is used as an evaluation medium in Arabic speaking skills courses. In this study, researchers used descriptive and analytical methods, because he dealt with a lot of information from students assigned to the class by observation and interview. The results showed that the steps in evaluating speaking skills included 3 stages, first the preparation or making of a video, then the upload stage and finally the assessment stage itself. while the phenomenon that arises when using youtube as an evaluation medium is the increased enthusiasm and motivation of students when speaking Arabic, especially when they know that they will publish it to YouTube students are more enthusiastic and serious in showing their speaking skills. with the use of youtube as an evaluation medium, it raises the phenomenon of increasing student scores, almost overall students get good grades, apart from that the videos they make can also be used as an interesting, fun, and easy learning media. In addition to these two results, evaluating speaking skills by speaking through videos uploaded on YouTube also makes the evaluation process construct valid.

The contention centres on issues such as the tax base, tax incidence, efficiency, and particularly, equity or fairness, among others. Qualities like ease of collection, difficulty of avoidance, accountability, and transparency etc., that ordinarily mark out property tax as a good tax in principle, are often compromised by controversial policies and mal-administration, particularly the latter. The new Lagos State Land Use Charge2018 (LUC, 2018) came into force effective January, 2018. Ina similar version that its immediate predecessor, the Land Use Charge2001 (LUC, 2001), attracted spontaneous and widespread protests on promulgation, the criticisms and protests that greeted the passage LUC (2018)has been vehement and remained unabated until the government was forced, like it did with the erstwhile law, to succumb to substantial but arbitrary reductions in rates and allowances across board (at two different times to date) but without a formal amendment to the law; an exact replica of what transpired under the erstwhile law and which opened it to abuse and arbitrary implementation with its compliance and revenue yields implications. The last of these reductions which took place in August saw a whopping 50%, and 25% cut in assessed rates on commercial properties and industrial properties, respectively. This study employed the doctrinal research methodology whereby the valuation or assessment aspect of the LUC (2018) was diagnosed with a view to finding amicable resolutions to the equity problem that virtually crippled the effectiveness of LUC (2001) over its seventeen years of existence and is already threatening the survival of the new LUC (2018). Keywords: assessment criteria, equity and fairness, Land Use Charge (2018), property tax.

Pendidikan memerlukan proses yang terus menerus sehingga guru perlu meningkatkan profesionalismenya. Guru profesional tidak hanya menguasai bidang ilmu, bahan ajar, dan metode yang tepat, tetapi mampu mengembangkan empat komponen kompetensi guru yaitu pedagogik, kepribadian, profesional, dan sosial. Guru yang tidak mempunyai sikap profesional dapat menyebabkan siswa sulit berkembang dengan baik. Pembuatan media pembelajaran merupakan salah satu solusi untuk mengatisipasi media yang susah didapat Guru dapat membuat sendiri media pembelajaran sehingga tidak memerlukan biaya yang mahal. Pembelajaran menjadi relevan dengan media yang dikonsep sendiri oleh guru. ada cara yang mudah untuk guru untuk membuat media pembelajaran sendiri yaitu dengan slide master. Menu slide master terdapat dalam program Microsoft Power Point yang sering dipakai oleh guru. Slide Master mempunyai keunggulan yang interaktif sehingga dapat melibatkan siswa dalam pembelajaran. peneliti berinovasi untuk melakukan pelatihan pembuatan CD PITBUS (Pembelajaran Interaktif Buatan Sendiri) perlu digalakkan agar guru dapat membuat media pembelajaran berbasis multimedia sendiri. Program pelatihan pembuatan CD PITBUS ini akan dilaksanakan di SMP N 1 Turi.  Education requires a continuous process so that teachers need to improve their professionalism. Professional teachers not only possess the right field of knowledge, teaching materials, and methods, but can develop the four components of the competency of the teacher: pedagogic, personality, professional, and social. Teachers who have no professional attitude can cause students to be difficult to develop well. Learning media making is one of the solutions to the media that can be difficult to obtain Guru can create their own learning media so that it does not require expensive costs. Learning becomes relevant to the media that the teacher has conceptualized. There is an easy way for teachers to create their own learning media that is with master slides. The master slide Menu is included in the Microsoft Power Point program, which is often used by teachers. Master slides have an interactive advantage that can involve students in learning. Researchers are innovating to conduct a CD making training in PITBUS (interactive learning) needs to be encouraged so that teachers can make their own multimediabased learning media. The PITBUS CD making Program will be held at SMP N 1 Turi.
A ausência e o vácuo: Educação Ambiental e a Nova Lei do Ensino Médio brasileiro no século XXI
Authors: Colacios Roger Domenech , Locastre Aline Vanessa
Published: June 2020

Este artigo tem como objetivo analisar a Educação Ambiental junto ao Ensino Médio brasileiro no século XXI. Na mudança legislativa ocorrida em 2017, pode-se perceber que os antigos componentes curriculares foram agrupados por áreas de conhecimento. Diante disso, analisaremos o papel que a Educação Ambiental teria nessa nova conjuntura, na qual é notada uma espécie de ausência ou enfraquecimento da área. A partir de então procurou-se entender os motivos que levaram a essa situação, encontrando um vácuo de políticas públicas em Educação Ambiental desde 2012. A proposta aqui apresentada tem a intenção de entender essa ausência e esse vácuo dentro de uma análise histórica da Educação Ambiental e da legislação educacional brasileira no século XXI. Para compor a investigação, foram utilizados como fontes a Nova Lei do Ensino Médio, a Base Nacional Comum Curricular, além de outros documentos sobre a Educação Ambiental, como a Política Nacional de Educação Ambiental, o Programa Nacional de Educação Ambiental e acordos nacionais e internacionais. Também, como base de interpretação dos resultados foram utilizados autores da área de Educação Ambiental ou sobre Epistemologia Ambiental. O método utilizado foi a pesquisa documental e análise qualitativa, tendo como parâmetro de investigação o campo ambiental e o campo das políticas públicas. Enquanto resultado, espera-se mostrar a ausência de novas políticas para a Educação Ambiental, tendo em vista os desafios educacionais para o século XXI.
Econophysical bourse volatility – Global Evidence
Authors: Ghosh Bikramaditya , MC Krishna
Published: June 2020

Financial Reynolds number (Re) has been proven to have the capacity to predict volatility, herd behaviour and nascent bubble in any stock market (bourse) across the geographical boundaries. This study examines forty two bourses (representing same number of countries) for the evidence of the same. This study finds specific clusters of stock markets based on embedded volatility, herd behaviour and nascent bubble. Overall the volatility distribution has been found to be Gaussian in nature. Information asymmetry hinted towards a well-discussed parameter of ‘financial literacy’ as well. More than eighty percent of indices under consideration showed traces of mild herd as well as bubble. The same indices were all found to be predictable, despite being stochastic time series. In the end, financial Reynolds number (Re) has been proved to be universal in nature, as far as volatility, herd behaviour and nascent bubble are concerned.
The Cost of Using Cash and Checks in Uruguay
Authors: Álvez Marcelo , Lluberas Rodrigo , Ponce Jorge
Published: June 2020

The incorporation of new technologies to financial activities implies challenges and opportunities to financial authorities. They are reacting to the unavoidable trend towards digitalization of financial activities with the objective of preserving stable and efficient payment and financial systems. Uruguay, for instance, has promoted the use of electronic payment instruments and tested in the real economy a central bank digital currency called e-Peso. Digitalization of payment systems would reduce transaction costs by (partially) replacing less efficient means of payment, e.g. paper-cash and checks. In this paper we find that the cost of using cash in Uruguay is approximately 0.61% of GDP. Interestingly, 98.1% of this cost is borne by the private sector: banks and retailers 77.1% and households 21.0%. The cost of using checks is equivalent to 0.04% of GDP. Overall, replacing paper-cash and checks by other (electronic) means of payment would imply a transaction cost reduction for the private sector of the equivalent of up to 0.65% of GDP.
Web-based Financial Reporting Disclosure: Evidence from Selected Banks in the Kingdom of Saudi Arabia (KSA)
Authors: Sarea Adel M.
Published: June 2020

With insights drawn from legitimacy theory undergirding perceived relative factors expected to influence the level of Web-Based Financial Reporting Disclosure (WBFRD), this paper sheds light on the level of the Web-Based Financial Reporting Disclosure (WBFRD) in selected banks in the KSA in 2017. Several gauges exist for measuring the level of transparency and disclosure practices. As a result of the unique characteristics of the banking sectors operating in the KSA under the Sharia-compliant (Islamic) law, however, the researcher eschewed employing Standard & Poor’s Transparency and Disclosure checklist. Accordingly, the researcher designed a 90-item index based on metrics identified in previous studies. The selected banks in the KSA evince a high level of Web-Based Financial Reporting Disclosure (WBFRD) on the order of 76%. Regression analysis indicates a positive association between the independent variables Bank Size, Bank age, and Profitability on one side, and the dependent variable Web-Based Financial Reporting Disclosure (WBFRD) on the other side.
Macro Stress Testing Credit Risk: Case of Madagascar Banking Sector
Authors: Rakotonirainy Miora , Razafindravonona Jean , Rasolomanana Christian
Published: June 2020

This study proposes to assess the vulnerability of banking sector’s credit portfolio under macroeconomic shocks and to evaluate its impact on banking system capitalization. Our method uses the Global Vector Autoregressive (GVAR) Model to generate adverse macroeconomic scenarios. The GVAR model is combining by the satellite credit risk equation to find the non-performing loan under stress conditions. The advantage of using GVAR model is that on the one hand, it captures the transmission of global, external and domestic macroeconomic shocks on banks non-performing loans. On the other hand, this model considers the nonlinear pattern between business cycle and the bank credit risk indicator during the extreme events as highlighting by the macro stress test literature. The forecast of non-performing loan is then used to obtain stress projections for capital requirement for the banking system level. This article attempts to fill the lacks concerning the stress testing works about Madagascar which study is a recent framework, whose no study on dynamic macro stress testing was treated before. The Results outline the interaction of aggregate non-performing loan with macroeconomic evolution. The horizon of capital prediction shows that banking sector reacts most to a GDP shock. Also, Madagascar banking sector is quite resilient and remains sufficiently capitalized under all macroeconomic scenarios designed with a solvency ratio higher than the minimum regulatory CAR ratio.
ОРГАНИЧЕСКОЕ ЗЕМЛЕДЕЛИЕ В РОССИИ – БЛАГО ИЛИ КАТАСТРОФА?
Authors: Стекольников К.Е.
Published: June 2020

Органическое земледелие (ОЗ), активно внедряемое в России, не может быть альтернативой интенсивному земледелию и не станет таковым из-за присущих ему нерешаемых проблем и несоблюдения законов земледелия. ОЗ не позволит соблюсти законы возврата, а его продуктивность будет ограничена законом минимума. ОЗ всегда будет сопровождаться дефицитом фосфора и калия. Внедрение ОЗ не только не обеспечит получение экологически «чистой» продукции, но и не способно произвести необходимое количество продукции для населения России. Утверждения приверженцев ОЗ о безопасности природных руд, которые предлагается использовать для компенсации выноса питательных элементов, не имеет оснований. Почему химический элемент из минерального удобрения опасен, а из природной руды безопасен? Неужели так кардинально меняется природа и свойства химического элемента? Если следовать логике апологетов ОЗ, то это так. На синтез 1 моля азота симбиотические клубеньковые бактерии затрачивают 20,17 МДж, а технический азот получается при затратах 1,56 МДж, то есть он энергетически в 12,93 раза дешевле. Поэтому все рассуждения приверженцев ОЗ о «бесплатном» азоте безосновательны.
