In search of the contours of the post-COVID Sustainable Development Goals: The case of BRICS
Authors: Bobylev S. N. , Grigoriev L. M. , Beletskaya M. Yu.
Published: March 2021

The global COVID-19 pandemic and an unexpected recession of dangerous proportions have provided strong reasons to look at the Sustainable Development Goals (SDGs) from three perspectives: The SDGs as a victim of the 2020 recession; the SDGs as an opportunity for better coordination on the way out of the recession; and the SDGs as an object of modernization for better adaptation to the realities "on the world stage". The BRICS countries are interested in developing and implementing the SDGs on a global scale as a way to catch up. The authors propose a "pandemic protocol", as well as a change in the methodology for including indicators in the SDGs: the introduction of new indicators that are important for sustainability and the incorporation of cross-cutting key indicators for the SDGs, both new and existing.

Astrometric Membership Tests for the Zinn–Newell–Gibson UV-bright Stars in Galactic Globular Clusters
Authors: Bond Howard E.
Published: March 2021

In 1972, Zinn, Newell, & Gibson (ZNG) published a list of 156 candidate UV-bright stars they had found in 27 Galactic globular clusters (GCs), based on photographs in the U and V bands. UV-bright stars lie above the horizontal branch (HB) and blueward of the asymptotic giant branch (AGB) and red giant branch in the clusters’ color–magnitude diagrams. They are in rapid evolutionary phases—if they are members and not unrelated bright foreground stars. The ZNG list has inspired numerous follow-up studies, aimed at understanding late stages of stellar evolution. However, the ZNG candidates were presented only in finding charts, and celestial coordinates were not given. Using my own collection of CCD frames in u and V, I have identified all of the ZNG objects, and have assembled their coordinates, parallaxes, and proper motions from the recent Gaia Early Data Release 3 (EDR3). Based on the Gaia astrometry, I have determined which objects are probable cluster members (45% of the sample). For the members, using photometry from EDR3, I have assigned the stars to various evolutionary stages, including luminous post-AGB stars, and stars above the HB. I point out several ZNG stars of special interest that have still, to my knowledge, never been studied in detail. This study is an adjunct to a forthcoming survey of the Galactic GCs in the uBVI photometric system, designed for detection of low-gravity stars with large Balmer discontinuities.

Published: March 2021

Two dwarf galaxies, WOC2017-07 and PGC 704814, located in the vicinity of the nearby luminous spiral galaxy NGC 253 were observed with the Advanced Camera for Surveys on the Hubble Space Telescope. Their distances of 3.62 ± 0.18 Mpc and 3.66 ± 0.18 Mpc were derived using the tip of the red giant branch method. These distances are consistent with the dwarf galaxies being members of the NGC 253 group. Based on the radial velocities and projected separations of seven assumed dwarf companions, we estimated the total mass of NGC 253 to be (8.1 ± 2.6)1011

Published: March 2021

We have spectroscopically identified 600 new E+A galaxies and candidates across 16 fields totaling roughly 480 square degrees in the Sloan Digital Sky Survey. E+A galaxies are post-starburst systems that have undergone a significant burst of star formation within the past 1–2 Gyr and are now fully quenched. They comprise a small population that is key to understanding the transition from star-forming to quiescent galaxies. Our survey focused on four nearby rich clusters of galaxies and their surroundings: Virgo, Coma, Leo, and Hercules. 356 candidates were identified in the clusters, and an additional 244 were identified in control fields or otherwise outside cluster bounds. Understanding the distribution and dynamics of the E+As has the potential to shed light on the evolutionary mechanisms present within nearby cluster environments. In this note, we give a brief overview of our selection processes and locations, and report on ongoing analyses of the sample.
Searching for Extragalactic Star Formation in the M101 Group
Authors: Garner Ray , Mihos J. Christopher , Harding Paul , Watkins Aaron E.
Published: March 2021

We present deep, narrowband imaging of the nearby spiral galaxy M101 to search for star-forming dwarf galaxies and isolated H ii regions in the group environment. Isolated star-forming regions, unassociated with spiral arms, probe star formation (SF) at the lowest masses and environmental densities. Such objects may be isolated star-forming events or ongoing evidence of tidal interactions. Using the Burrell Schmidt telescope, we target the brightest emission lines of star-forming regions, Hα, Hβ, and [O iii], to detect potential isolated regions. Great care was taken to remove potential source contaminants, such as high-redshift objects and Galactic M stars, from our source list. For each detected source, we compare the emission line fluxes and equivalent widths, along with structural and photometric properties, to samples of Local Group dwarfs and star-forming galaxies in the SINGG/11HUGS samples. We discuss our findings in the context of SF in low-density environments and evolution of the M101 Group.

Published: March 2021

One of the Roman Space Telescopes principal science objectives is to measure dark energy's equation-of-state using a strategic combination of imaging and spectroscopic surveys at high galactic latitude. Type Ia Supernovae survey requirements demand 0.3% photometric accuracy and calibration of key systematic effects. One of these is count rate dependent nonlinearity (CRNL) that if uncorrected affects the accuracy of SNe Ia distance measurements. Romans Relative Calibration System (RCS) enables on-orbit measurement and tracking of CRNL, through a direct illumination mode and a simultaneous lamp plus scene mode. We present results on the impact of CRNL calibration on the dark energy figure of merit (FoM), for a specific reduction of RCS capabilities. We examined many combinations of illumination and passbands, finding that only six meet the requirements. No RCS at all results in a factor of 5 degradation in the FoM.

Prise de conscience du risque climatique et de sa dimension systémique
Authors: Clerc Laurent
Published: March 2021

La prise de conscience collective de la nature systémique du changement climatique est récente. Elle a notamment émergé dans le contexte de réunions internationales placées sous l’égide de l’Organisation des Nations Unies (ONU) et des rapports du Groupe intergouvernemental d’experts sur le climat (GIEC), qui ont reconnu la responsabilité de l’homme dans ce changement. Elle a été beaucoup plus tardive dans le domaine économique et financier où, en dépit d’une accélération de la mobilisation des autorités et des acteurs depuis 2015, les institutions financières peinent à prendre en compte cette nature systémique du changement climatique et à l’intégrer dans leur cadre de gestion des risques financiers et extra-financiers. Une modification de la régulation financière est également nécessaire pour accélérer cette prise en compte.
Les risques juridiques et réputationnels
Authors: Parance Béatrice
Published: March 2021

La pression exercée par les ONG et la société civile sur les investisseurs se renforce afin de les placer face à leur responsabilité sociétale. Elle s’exerce en amont en usant du ressort réputationnel mis en scène par l’engagement actionnarial et les obligations de transparence qui ne cessent de croître. En ce sens, le règlement européen Discloser de novembre 2019 vient imposer aux investisseurs de rendre compte de la prise en considération des risques ESG susceptibles d’avoir une incidence négative sur leurs investissements. En aval, les actions en responsabilité tendent à se multiplier pour que les investisseurs soient comptables des impacts de leurs investissements sur le changement climatique. Ces actions pourraient prendre appui sur le devoir de vigilance instauré en France par une loi de 2017, et qui pourrait être étendu à l’échelle européenne dans un futur très proche.
La mesure de l’empreinte biodiversité comme outil d’atteinte des objectifs globaux
Authors: Berger Joshua , Cadi Antoine , Ménard Sophie , Vallier Antoine
Published: March 2021

La crise multidimensionnelle actuelle souligne plus encore, si cela était nécessaire, l’urgence de lutter contre la dynamique d’effondrement de la biodiversité en s’attaquant à ses causes principales pour avancer vers un modèle de société plus durable. Pour y contribuer, les entreprises ont besoin de disposer de cibles, de scénarios et d’outils. Elles ont également besoin de partenaires crédibles pour développer et mettre en œuvre dans la durée leur stratégie en faveur de la biodiversité. Pour ce faire, il existe un certain nombre d’initiatives contribuant au développement des outils nécessaires à la mesure de l’empreinte biodiversité et à la mise en évidence des actions permettant de réduire effectivement les pressions sur la biodiversité. Parmi ces outils, le Global Biodiversity Score (GBS) est un outil de mesure de l’empreinte biodiversité concourant à l’atteinte de l’objectif global d’inversion de la courbe d’érosion de la biodiversité. Au sein des acteurs économiques, la communauté financière peut jouer un rôle-clé dans l’inversion de la perte de biodiversité en choisissant les projets et les investissements ayant les impacts les plus positifs sur la nature.
Covid-19 et CO 2 : la finance peut-elle contribuer à la convergence des luttes ?
Authors: de Perthuis Christian
Published: March 2021

En 2020, la lutte contre la circulation du virus a nettoyé le ciel et fait baisser les émissions de CO 2 comme nul autre événement auparavant. La recherche d’une plus grande résilience face à la pandémie a renforcé l’action face au risque climatique. S’agit-il d’une conjoncture fortuite qui disparaîtra avec l’amenuisement de la charge virale ? Sous le choc de la pandémie, les sociétés pourraient au contraire amorcer un virage plus durable vers la résilience, en faisant converger la lutte contre la circulation des virus et celle contre la prolifération du CO 2 . Cet article examine comment une telle convergence pourra s’organiser à moyen et à long termes et trace quelques voies permettant à la finance d’y contribuer véritablement.
L’évolution de la recherche sur le démantèlement des organisations
Authors: Lim Jae Young
Published: March 2021

Depuis plusieurs dernières décennies, la recherche sur le démantèlement connaît une transformation, passant d’un domaine obscur à un domaine en croissance rapide. Depuis le début des recherches dans les années 70, les pressions internationales, toujours plus nombreuses, en faveur de l’austérité gouvernementale nécessitent une compréhension systémique du démantèlement des organisations. Dans le présent article, nous examinons l’évolution de la recherche sur le démantèlement dans les organisations, qui est passée d’études de cas à des études statistiques. Nous formulons ensuite plusieurs suggestions sur les moyens de faire avancer la recherche sur le démantèlement dans les organisations. Remarques à l’intention des praticiens Le présent article propose des enseignements pratiques aux praticiens qui souhaitent comprendre la question du démantèlement des organisations. En présentant l’évolution des recherches sur le démantèlement des organisations depuis leur création jusqu’à aujourd’hui, nous donnons un aperçu succinct de la question du démantèlement des organisations. Notre article intéressera dès lors ceux qui doivent opérer dans le monde d’aujourd’hui, où les pressions en faveur de l’austérité budgétaire sont de plus en plus fortes.
The optimal pricing and service strategies of a dual-channel retailer under free riding
Authors: Guo Jinsen , Zhou Yongwu , Li Baixun
Published: March 2021

Free riding refers to that in a multi-channel market, consumers enjoy the presale service of a product at one channel but purchase the product at another channel. In this paper, we study the optimal pricing and service strategies for a dual-channel retailer, who sells a product through both a traditional retail channel and an online channel. We assume that the offline channel provides the presale service but the online channel does not. We investigate how the changes of the degree of free riding affect the pricing/service strategies and profits of the two channels under three different scenarios: Stackelberg competition, Bertrand competition and channel integration. Our analysis shows that when the dual-channel retailer operates the two channels separately, no matter under which competitive scenario, free riding has a negative effect on both channels. And it is much more beneficial for the dual-channel retailer to let one channel work as a leader and another channel as a follower than to let the two channels make their decision simultaneous. In contrast, when the dual-channel retailer runs the two channels jointly, i.e., employs the channel-integration scenario, free riding may be beneficial to the retailer. Finally, this paper proposes and analyzes a revenue-sharing contract to coordinate a decentralized dual-channel retailer to achieve beneficial outcomes for both channels.
Supply chain coordination considering e-tailer's promotion effort and logistics provider's service effort
Authors: Tu Jun , Sun Zijiao , Huang Min
Published: March 2021

Promoting the sale of green agriculture products through online platforms has become the main focus of agricultural industries. In a supply chain consisting of an e-tailer and third-party logistics (TPL), both the promotion effort of the e-tailer and the logistics service effort of TPL can affect the demand. Considering that logistics service contracts may be provided by the e-tailer or TPL, this study defines two different timing sequences. Three types of contracts, i.e., fixed-price, revenue-sharing, and cost-sharing contracts, are used to coordinate the supply chain. The game models under different timing sequences and different contract scenarios are established and solved. The promotion effort and logistics service effort under different scenarios are compared theoretically and numerically. The results indicate that both the promotion effort and logistics service effort change with timing sequences and contract types. The timing sequences depending on the contract provider significantly affect the performance of the supply chain. The cost-sharing contract provided by the TPL can motivate the e-tailer to apply the largest effort, and vice versa. The cost-sharing contract provided by the e-tailer can achieve the largest demand that is optimal for both the e-tailer and supply chain. However, the optimal contract for the TPL is conditional.
Design of path planning and tracking control of quadrotor
Authors: Gao Yi , Li Rui , Shi Yingjing , Xiao Li
Published: March 2021

In this paper, we first design a motion planning system based on the Batch Informed Trees (BIT*) algorithm for quadrotor and a linear model predictive control (LMPC) is applied to solve the path tracking problem for a quadrotor. BIT* algorithm is used to plan a barrier-free trajectory quickly in an obstructed environment. Then we apply linear model predictive control for the full state quadrotor system model to track the generated trajectory. Finally, the BIT* algorithm simulation case is presented using RVIZ visual interface and some simulation cases are presented using MATLAB / Simulink. The results demonstrate the capability and the effectiveness of the control strategy in fast path tracking and the quadrotor stability, while the desired performance is achieved.
Adorno humoriste malgré lui
Authors: Birnbaum Antonia
Published: March 2021

What insight is there to gain when Adorno is put “beside himself”? The humoristic tendency of Theodor W. Adorno and Max Horkheimer’s famous essay on the culture industry highlights the non-categorical modalities borrowed from the avant-gardes and psychoanalysis that disorganize Kant’s supposedly invariant concepts a priori: partialities of the driven montage, allegorisation. This tendency opens on the decentering consequences for the thinking of another subject, beyond the logic of suspicion and the melancolic jouissance that block it.
The Immanence of Truths and the Absolutely Infinite in Spinoza, Cantor, and Badiou
Authors: Ndiaye Berankova Jana
Published: March 2021

The following article compares the notion of the absolute in the work of Georg Cantor and in Alain Badiou’s third volume of Being and Event: The Immanence of Truths and proposes an interpretation of mathematical concepts used in the book. By describing the absolute as a universe or a place in line with the mathematical theory of large cardinals, Badiou avoided some of the paradoxes related to Cantor’s notion of the “absolutely infinite” or the set of all that is thinkable in mathematics W: namely the idea that W would be a potential infinity. The article provides an elucidation of the putative criticism of the statement “mathematics is ontology” which Badiou presented at the conference Thinking the Infinite in Prague. It emphasizes the role that philosophical decision plays in the construction of Badiou’s system of mathematical ontology and portrays the relationship between philosophy and mathematics on the basis of an inductive not deductive reasoning.
An Elementary Peircean and Category-Theoretic Reading of Being and Event, Logics of Worlds, and The Immanence of Truths
Authors: Zalamea Fernando
Published: March 2021

The article presents a reading of Badiou’s trilogy, L’Être et l’événement (1988), Logiques des mondes (2006), and L’Immanence des vérités (2018), and points out the mathematical connections with the works of Cohen, Grothendieck, and large cardinal specialists. A synthetic rendering of these connections is first offered, following precise passages in Badiou’s work, then a category-theoretic and Peircean perspective is explored in order to specify the many dialectics in the trilogy, and, finally, some open problems are proposed.
Chibanis and chibanias or long-term (in)hospitality
Authors: Leblanc Julie , Pinel Jordan
Published: March 2021

In this paper, we discuss the concept of (in)hospitality and its implications in the daily life of elderly immigrants in France today. On the basis of the qualitative surveys we used, we have come to focus more specifically on the ageing of chibanis and chibanias, those immigrants who came to France mostly under state migration programmes from the 1960s onwards. Some of them face unsafe and precarious living conditions and severe cuts in their social rights, thereby epitomizing the inhospitable practices of institutions. In light of this, we argue that it is the local actors of hospitality, often associations, who have to take over and try to redress situations that are perceived as unfair. The people concerned also participate in (re)creating spaces for hospitality and mutual aid in places such as cafés, but also in conquering and asserting their rights and the social recognition they lack. These actors of civil society are mobilised “here” and “there”, i.e. both in the host country and in the country of origin – Morocco in this case study –, which is somehow reminiscent of the “in-between” life for part of these now ageing populations.
Community Colleges and Workforce Preparation in the 21st Century
Authors: Lopez Carlos
Published: March 2021

This chapter addresses the modern trend in community colleges and their evolving mission to serve as one of the significant contributors to workforce development in our nation. There are many challenges community colleges face today. One of those challenges is to be one of the main suppliers of skilled professionals for the workforce. Therefore, it is crucial to understand the role of community colleges, their mission, and how they will develop programs to train people with the necessary skills to meet the demands of the workforce. For community colleges to achieve that goal, they have to go from adding and/or restructuring curricula to making sure they have the right personnel to teach special and high tech courses that will prepare students with the right skill set and knowledge to join the workforce after getting their degree, diploma, or certification at the community college.

Cluster Identification in Metagenomics – A Novel Technique of Dimensionality Reduction through Autoencoders
Authors: Wijegunarathna Kalana , Maduranga Uditha , Weerasinghe Sadeep , Perera Indika , Wickaramarachchi Anuradha
Published: March 2021

Analysis of metagenomic data is not only challenging because they are acquired from a sample in their natural habitats but also because of the high volume and high dimensionality. The fact that no prior lab based cultivation is carried out in metagenomics makes the inference on the presence of numerous microorganisms all the more challenging, accentuating the need for an informative visualization of this data. In a successful visualization, the congruent reads of the sequences should appear in clusters depending on the diversity and taxonomy of the microorganisms in the sequenced sample. The metagenomic data represented by their oligonucleotide frequency vectors is inherently high dimensional and therefore impossible to visualize as is. This raises the need for a dimensionality reduction technique to convert these higher dimensional sequence data into lower dimensional data for visualization purposes. In this process, preservation of the genomic characteristics must be given highest priority. Currently, for dimensionality reduction purposes in metagenomics, Principal Component Analysis (PCA) which is a linear technique and t-distributed Stochastic Neighbor Embedding (t-SNE), a non-linear technique, are widely used. Albeit their wide use, these techniques are not exceptionally suited to the domain of metagenomics with certain shortcomings and weaknesses. Our research explores the possibility of using autoencoders, a deep learning technique, that has the potential to overcome the prevailing impediments of the existing dimensionality reduction techniques eventually leading to richer visualizations.

Purpose: This study compared maternal age at childbirth, the number of live births, and the weight of live births between Korean women and immigrant women using statistical data from the Republic of Korea for 2018. Methods: The analysis was conducted using data from the Microdata Integrated Service of Statistics Korea (https://mdis.kostat.go.kr/index.do). Results: Korean women and immigrant women showed a higher age at childbirth in 2018 than in 2008. The percentage of newborns of Korean women with a birth weight of less than 2.5 kg increased slightly for 3 consecutive years from 2016 to 2018, whereas for immigrant women, this percentage increased in 2017 compared to 2016 and then decreased again in 2018. Very low birth weight (less than 1.5 kg) became more common among immigrant women from 2016 to 2018. Birth at a gestational age of fewer than 37 weeks increased both among Korean and immigrant women from 2016 to 2018. In both groups, the percentage of women who had their first child within their first 2 years of marriage decreased from 2008 to 2018. Conclusion: Immigrant women had higher birth rates than Korean women, while both groups showed an increasing trend in premature birth. Greater attention should be paid to the pregnancy and birth needs of immigrant women, and steps are needed to ensure health equity and access in order to prevent premature births. It is also necessary to identify factors that affect preterm birth and birth of very low birth weight infants among immigrant women in the future.

Published: March 2021

BackgroundIntravenous (IV) dexamethasone prolongs the duration of a peripheral nerve block; however, there is little available information about its optimal effective dose. This study aimed to evaluate the effects of three different doses of IV dexamethasone on the duration of postoperative analgesia to determine the optimal effective dose for a sciatic nerve block.MethodsPatients scheduled for foot and ankle surgery were randomly assigned to receive normal saline or IV dexamethasone (2.5 mg, 5 mg, or 10 mg). An ultrasound-guided popliteal sciatic nerve block was performed using 0.75% ropivacaine (20 ml) before general anesthesia. The duration of postoperative analgesia was the primary outcome, and pain scores, use of rescue analgesia, onset time, adverse effects, and patient satisfaction were assessed as secondary outcomes.ResultsCompared with the control group, the postoperative analgesic duration of the sciatic nerve block was prolonged in groups receiving IV dexamethasone 10 mg (P < 0.001), but not in the groups receiving IV dexamethasone 2.5 mg or 5 mg. The use of rescue analgesics was significantly different among the four groups 24 h postoperatively (P = 0.001) and similar thereafter. However, pain scores were not significantly different among the four groups 24 h postoperatively. There were no statistically significant differences in the other secondary outcomes among the four groups.ConclusionsThis study demonstrated that compared to the controls, only IV dexamethasone 10 mg increased the duration of postoperative analgesia following a sciatic nerve block for foot and ankle surgery without the occurrence of adverse events.

Background:

The clinical spectrum of contactin-associated protein-like 2 (CASPR2) antibody-associated disease is wide and includes Morvan syndrome. Studies describing treatment and long-term outcome are limited.

Aims:

We report the clinical profile and emphasize response to treatment and long-term outcome in eight patients with CASPR2-antibody-associated disease.

Methods:

Clinical, radiological, electrophysiological, treatment, follow-up, and outcome data were collected by retrospective chart review.

Results:

Clinical manifestations included Morvan syndrome (n = 7) and limbic encephalitis (n = 1). None of the patients were positive for LGI1 antibody. Associated features included myasthenia (n = 1), thymoma (n = 1), and dermatological manifestations (n = 4). Patients were treated with intravenous methylprednisolone and plasma exchange during the acute symptomatic phase followed by pulsed intravenous methyl prednisolone to maintain remission. Mean-modified Rankin score at admission (pre-treatment), discharge, and last follow-up were 3.75, 2.5, and 0.42, respectively. One patient with underlying thymoma and myasthenic crisis died. The other seven patients were followed up for a mean duration of 19.71 months. All of them improved completely. Relapse occurred in one patient after 13 months but responded favorably to steroids.

Conclusion:

CASPR2 antibody-associated disease has favorable response to immunotherapy with complete improvement and good outcome. Underlying malignancy may be a marker for poor prognosis.
Polymorphic Amyloid Degeneration of the Cornea
Authors: Modabber Milad , Cortés Dennis E. , Mannis Mark J.
Published: March 2021

We report a rare case of polymorphic amyloid degeneration (PAD) with in vivo confocal microscopy and anterior segment optical coherence tomography (AS-OCT). A 74-year-old female presented to our service for suspected Fuchs corneal dystrophy. Her best-corrected visual acuity was 20/25 right eye (OD) and 20/20 left eye (OS). Slit-lamp biomicroscopy revealed bilateral punctate, refractile deposits in the deep stroma in an annular distribution with relative sparing of the central cornea. The remainder of the ocular examination was within expected limits. Central pachymetry was 546 μ OD and 535 μ OS. AS-OCT demonstrated focal hyper-reflective lesions in the deep stroma. Specular microscopy showed normal endothelial cell count and morphology. Confocal microscopy highlighted bright, enhancing punctate lesions in both the anterior stroma and deep stroma with normal intervening spaces. The patient was managed conservatively. Altogether, PAD is a rare, sporadically inherited condition that presents in the elderly. Confocal microscopy can aid in the diagnosis.
Identification of Substandard and Falsified Medicines: Influence of Different Tolerance Limits and Use of Authenticity Inquiries

Published: March 2021

Substandard and falsified medicines have severe public health and socioeconomic effects, especially in low- and middle-income countries. The WHO has emphasized the need for reliable estimates of the prevalence of such medicines to efficiently respond to this problem. In the present study, we used 601 medicine samples collected in Cameroon, the DR Congo, and Malawi to assess the rates of substandard and falsified medicines based on different criteria. Based on the specifications of the U.S. Pharmacopoeia for the amount of the active pharmaceutical ingredients, the rate of out-of-specification medicines was 9.3%. By contrast, this rate ranged from 3.3% up to 35.0% if the tolerance limits of other pharmacopoeias or recently published medicine quality studies were used. This shows an urgent need for harmonization. Principal methods to assess the rate of falsified medicines are packaging analysis, chemical analysis, and authenticity inquiries. In the present study, we carried out an authenticity inquiry for the aforementioned medicine samples, contacting 126 manufacturers and 42 distributors. Response rates were higher for samples stated to be manufactured in Asia (52.4%) or Europe (53.8%) than for samples manufactured in Africa (27.4%; P < 0.001). One sample had been identified as falsified by packaging analysis by the local researchers and two additional ones by chemical analysis. Notably, seven additional falsified samples were identified by the authenticity inquiries. The total rate of falsified medicines resulted as 1.7%. Considerations are discussed for assessing the rates of “substandard” and “falsified” medicines in future medicine quality studies.
The Ambiguity of Musical Expression Marks and the Challenges of Teaching and Learning Keyboard Instruments: The Nnamdi Azikiwe University Experience
Authors: Okeke Ikedimma Nwabufo
Published: March 2021

The relevance of musical expression marks —technical words, symbols, phrases, and their abbreviations— in music is to guide the performer through a thorough interpretation and appreciation of the dynamics and subtleties of a piece of music. These marks, though fundamental to piano pedagogy, sometimes appear confusing to the enthusiastic piano student owing to the fact that some of the performance marks demand subjective expressions from the performer such as, ‘furiously’, ‘fiercely’ ‘with agitation’ ‘brightly’, tenderly, etc. Piano-keyboard education is still a ‘tender’ art in Nigerian higher institutions where most learners start at a relatively very late age (17-30 yrs) and so, it becomes burdensome and sometimes unproductive to encumber the undergraduate piano-keyboard student with a plethora of performance marks when he is still grappling with scales and arpeggios. This paper therefore suggests teaching keyboard basics and technique and employing fundamental musical expression marks/dynamics first for undergraduate piano teaching and learning in our institutions. Only when students have shown competences in the basic dynamic/expression marks such as, crescendo, accelerando, andante, moderato, allegro, larghetto etc, can the more complex and subjective ones be introduced in their keyboard repertoire.
Indigenous language implementation and nation building: the Nigerian experience
Authors: Amechi Adaku
Published: March 2021

The National Policy on Education has done well to cover education levels ranging from the early childhood/pre-primary, to the primary and the secondary school levels. It even emphasized the use of mother tongue at the kindergarten and nursery school levels. Yet our educators at the kindergarten and nursery school merely pay lip-service to it. Despite the fact that the language policy on education emphasized the use of mother tongue at these levels as a medium of instruction, the English language continues to dominate our indigenous languages because it has been adopted at the kindergarten and nursery school levels. The study is a survey of Nigerian indigenous language implementation and use in the pre-primary schools in Ado-Ekiti, Ekiti State. Thirty-five preprimary schools were selected for the study. They represented three categories of pre-primary schools in Ekiti State as follows: government-owned/public schools, missionary schools and private schools. A six-item questionnaire was used to collect data from the three categories of pre-primary schools. For proper presentation, the paper focused on quest for national integration, ethnicity and dialectal differences, the policy, why the kindergarten and nursery schools, a study of sampled pre-primary schools in Ado-Ekiti, and the challenges of indigenous language policy implementation in Nigerian early childhood/pre-primary schools. The study identified some problems, which include lack of teachers specialized in Child Education, proliferation of private schools, and lack of adequate supervision by the appropriate body. The paper concluded by giving suggestions and recommendations towards the proper implementation and use of Nigerian indigenous languages in preprimary schools via in-depth and focused supervision.Keywords: Indigenous languages, Policy implementation, Nation building, Early childhood, Nigeria

A political speech is usually characterized by the use of different linguistic techniques and strategies that allow politicians to convey their political messages and persuade people of their ideologies and thoughts. The American presidential inaugural address is therefore a form of political discourse that imbues the characteristics of both written and oral discourse. This study consequently looked at how Presidents Barrack Obama and Donald Trump of America have used Linguistic resources (Pronouns and metaphors) to construct individual and collective ideologies and persuade America to accept their political ideologies. This exploration was carried out within the frameworks of Lakoff and Johnson Conceptual Metaphor Theory, Charter is – Black’s Critical Metaphor Theory and the content method of data analysis. The corpus was drawn from the respective official websites of Barrack Obama and Donald Trump. It was discovered that their speeches were characterized by skilful choice of rhetorical strategies to make their speeches effective in order to convince the electorates. President Obama used more of inclusive pronouns and metaphors to support and advocate for multilateralism and internationalism while Donald Trump used pronouns and metaphors that distanced him from the corrupt government that led to unemployment in America while supporting and advocating a strong American interest.
Characterization and Assessment of Genetic Diversity for Agro-Morphological Traits of Ethiopian Chickpea (Cicer arietinum L.) landraces
Authors: Awol Mohammed
Published: March 2021

This experiment was conducted in 2016 at Sirinka and Jari, under rainfed conditions to characterize and assess genetic diversity among the Ethiopian chickpea landraces. Two hundred two new germplasm accessions were grown in an alpha lattice design with three replications. Data on 16 traits were collected and analysed. Differences among the accessions were significant  P<0.01). The genotypes were grouped into five clusters with different sizes. The genetic distances among the clusters were significant. The highest diversity indices pooled over characters within zones were recorded for accessions from South West Shewa (H= 2.03 ± 0.05) followed by Gurage (H=0.81 ± 0.08), West Shewa (H=0.73 ± 0.04) and North Gonder (H= 0.72 ± 0.05). The existence of wider morpho-agronomic diversity among the chickpea collections implies the potential to improve the crop and the need to conserve the diversity. Future collecting operations of chickpea accessions should strategically focus on areas with relatively large variation. From a genetic conservation point of view, it appears that South West Shewa, Gurage, West Shewa and North Gonder could be suitable as in situ conservation sites. Keywords: Accessions; diversity; clustering
