Authors: Buldgen A. , Detimmerman F. , Sall B. , Compère Roger
Published: January 2021

Les paramètres démographiques et zootechniques des élevages de poules traditionnels sont décrits à partir d'une enquête réalisée dans 85 unités de production villageoises du bassin arachidier sénégalais. L'élevage de sujets locaux en conditions intensives à l'Ecole nationale supérieure d'agriculture permet, en outre, d'évaluer le potentiel génétique de la race locale. Les exploitations avicoles villageoises de taille réduite comportent en moyenne 10 sujets. Le système d'élevage très rudimentaire assure une faible productivité : croissance très lente, ponte faible et irrégulière (poids adulte de 1200 g atteint en 26 semaines et ponte de 40 à 50 oeufs par poule en 52 semaines). L'amélioration des conditions d'élevage ne permet pas d'augmenter les performances pondérales. Elle assure toutefois une production supplémentaire de 50 oeufs par poule et par an. En raison du potentiel de production très limité de la poule locale, l'augmentation des performances en conditions d'élevage améliorées dépend de la réalisation de croisements améliorateurs à partir de races européennes, suffisamment rustiques de préférence.

It is substantiated that the project activity, which is used in the teaching process of students, contributes to the development of knowledge, skills, it is able to form the competencies they need, to become a versatile personality. It is proved that in the educational environment, willingness to learn new knowledge, skills, focus on results, hard work is being developed, creative thinking is developing, and most importantly, high skill and qualifica-tion are acquired. It is concluded that the design process is a kind of transition of the student from one state to another, step-by-step conditions that allow you to achieve great educational, practical results in a shorter period of time. The design process is the most effective and comfortable for students, since this process focuses on the individuality of each person, which, in the process of joint, teamwork, undergoes changes in the student himself, by taking a certain role in the design process. It is proved that the creation in the educational environment of the most favorable condi-tions for the development of students’ skills leads to the successful and effective formation of a holistic, informed personality, which, in turn, is the driving force for the development of society as a whole. The skills that a graduate possesses determine the level of development of the educational environment.
Parameters of the development of social and cultural environment of the city (on the issue of social and cultural urbanism specifics)
Authors: Dolzhenkova Marina I. , Bortnikova Tatyana G.
Published: January 2021

The study is devoted to examining the essence of the phenomenon of social and cultural urbanism – an extensive interdisciplinary field of research devoted to cities and the processes of urban lifestyle formation, urban leisure, overcoming depersonalization, asociality and isolation of citizens, their mutual alienation and antipathy. The modern city is considered as a specific, ration-ally organized territory; a special self-developing whole organism, where a uniquely organized so-cial and patial environment arises, the form of existence of a particular society. The problems of social and cultural urbanism are connected with mass urban culture and leisure, within the frame-work of which projects of recreation zones are being developed that positively affect the develop-ment of urban spaces and communities, making them attractive to residents and tourists. In any urban environment, a special way and type of culture develops; in the structure of the settlement functional clusters are formed that integrate the life, work and leisure of citizens. The quality of human life largely depends on the state of the social and cultural environment created in the city (quality of housing, public services, communications, trade, health care, education, etc.). The ur-ban social and cultural environment is positioned as a complex self-organizing subsystem of the urban structure, characterized by a number of quantitative and qualitative indicators. The urban environment through the methods of people interaction forms a unique social and psychological type of personality, which is characterized by rationality, mobility, willingness to change, the sub-ordination of one’s own interests to the needs of others, the ability to overcome the difficulties of reality. Common problems of the urban social and cultural environment are insufficient cultural and leisure infrastructure; low living standards and purchasing power of the population; lack of sustainable cultural and historical traditions; lack of active partnership between organizations of the spheres of culture, leisure and art in solving city problems.

Published: January 2021

Described are some of the key parameters of civil-patriotic identity of student youth. The empirical basis of the study was data of questionnaire survey of students, studying at higher educational institutions of Tyumen on a full-time basis. The survey was conducted by questionnaire method (n = 594), the sample was formed through spontaneous selection of respondents. Three groups of young people were identified, depending on their patriotic self-identification, i.e. “patriots”, “non-patriots” and “vacillating”. Patriotic aspect of self-identification correlates with civic and other forms of social identity, as well as some elements of civic subjectivity. Comparative analysis of selected groups was carried out, according to different indicators of civic orientations and identifications, in particular, subjective significance of citizenship, need to contribute to well-being of the country, degree of interest in history of Russia, emotional connection with symbols of the country, active civic attitudes. The analysis of empirical data also made it possible to identify statistical relationship between self-identification as patriots and communities of different sizes. The conclusion is made about intersection of patriotic and civil identity in terms of civil obligations, responsibility, as well as implementation of symbolic civil actions. In contrast, attitudes associated with critical citizenship are weakly associated with identification of modern students as patriots.

Presented is the analysis of correct choice of EFL Textbooks in the context of developing students’ effective communicative writing skills. Despite the needs of society for specialists, able to write in foreign language, most school graduates are not ready for written intercultural communication. Today, we should change the strategy of developing written communication skills and consider them as a goal, rather than as a means of teaching and learning. The paradigm shift is supposed to be reflected in training materials that should be appropriately selected in accordance with the goal. To be effective, the choice of training aids ought to be based on appropriate criteria. Our research was aimed to determine criteria for selecting EFL textbooks for effective developing written communication skills of students. The proposed criteria were verified in series of modern English textbooks.
Between philosophy, science, politics: Anthropology of Marxism by C. Robinson
Authors:   Institute of Philosophy of the Russian Academy of Sciences, Shuliko G.A.
Published: January 2021

Presented is a review of latest edition of book by C. Robinson’s (1946–2016) “An anthropology of Marxism". The article begins with a short introduction to why Robinson’s work might be of interest to Russian reader. What follows is a critical analysis of how Robinson views Marxist views of his own conceptual history. Skillfully combining the civilizational approach and the principle of historicism, Robinson comes to the conclusion, that there are a number of weaknesses in the materialist conception of history. One of the key weaknesses, from Robinson’s point of view, is the history of pre-capitalist European socialism, i.e. Marxism, due to specific perception of capitalism, is divorced from the centuries-old history of European actions of social lower classes. Rethinking the historical place of Marxism can productively affect both the study of Marxism itself and socio-political ideas about humanity as a whole. Using a number of historical examples, Robinson shows the importance of various pre-capitalist forms of social consciousness (ancient philosophy, religion, etc.) for formation of the socialist movement in its classical forms.

Authors: Zhegulskaya Yu. V.
Published: January 2021

The decree of the President of the Russian Federation declared 2019 as the Year of Theatre. Libraries traditionally participate in promotion of theatre art, provide their places for plays, hold art meetings, organize theatre clubs, and use theatrical tools in club activities to hold public events. The article objective is to identify and characterize types, forms, orientation, and specifics of cultural, educational, and leisure activities implemented by the central universal scientific libraries of the Siberian Federal district (SFD) as part of the Year of Theater. 10 central libraries were chosen to be analyzed: Altai Regional Universal Scientific Library named after V. Y. Shishkov (Barnaul), Irkutsk Regional State Universal Scientific Library named after I. I. Molchanov- Sibirsky, State Scientific Library of the Kuzbas named after V. D. Fedorov (Kemerovo), Krasnoyarsk Regional State Universal Scientific Library, Novosibirsk State Regional Scientific Library, Omsk State Regional Scientific Library named after A. S. Pushkin, National Library named after M. V. Chevalkov (Gorno- Altaisk), National Library of the Tuva Republic named after A. S. Pushkin (Kizil), National Library named after N. G. Domozhakov (Abakan), Tomsk Regional Universal Scientific Library named after A. S. Pushkin. The source bases of this study were public plans and reports of libraries, news and events reports posted on the official libraries websites. The theatre topic reflects itself in preparing various libraries exhibitions, chronographs publications, organizing meetings with culture and arts figures, clubs work, organizing competitions, cultural and educational events and projects, holding festivals. Sociocultural event “Library Night 2019” aimed at supporting reading was a bright manifestation of the “Library + Theater” union. Libraries used the following forms of events: performances, concerts, lectures, master classes, exhibitions, excursions, quizzes, competitions, playgrounds. The events held during the Year of Theatre varied in content and combination of traditional and new forms; had strongly marked book and reading popularization; were oriented on different age groups, interactive; used many multimedia products. Although the chosen forms of the events are alike, the fact that each library has its unique content based on local history makes special cultural and leisure activities of every library.

Published: January 2021

Ischemic stroke is one of the most disabling diseases and a leading cause of death globally. Despite advances in medical care, the global burden of stroke continues to grow, as no effective treatments to limit or reverse ischemic injury to the brain are available. However, recent preclinical findings have revealed the potential role of transient receptor potential cation 6 (TRPC6) channels as endogenous protectors of neuronal tissue. Activating TRPC6 in various cerebral ischemia models has been found to prevent neuronal death, whereas blocking TRPC6 enhances sensitivity to ischemia. Evidence has shown that Ca2+ influx through TRPC6 activates cAMP response element-binding protein (CREB), an important transcription factor linked to neuronal survival. Additionally, TRPC6 activation may counter excitotoxic damage resulting from glutamate release by attenuating the activity of NMDA receptors of neurons by posttranslational means. Unresolved though, are the roles of TRPC6 channels in non-neuronal cells such as astrocytes and endothelial cells. Moreover, TRPC6 channels may have detrimental effects on the blood-brain barrier, although their exact role in neurovascular coupling requires further investigation. This review discusses evidence-based cell-specific aspects of TRPC6 in the brain to assess the potential targets for ischemic stroke management.
Leucokinin and Associated Neuropeptides Regulate Multiple Aspects of Physiology and Behavior in Drosophila
Authors: Nässel Dick R.
Published: January 2021

Leucokinins (LKs) constitute a family of neuropeptides identified in numerous insects and many other invertebrates. The LKs act on G-protein coupled receptors that display only distant relations to other known receptors. In adult Drosophila, 26 neurons/neurosecretory cells of three main types express LK. The four brain interneurons are of two types, and these are implicated in several important functions in the fly’s behavior and physiology, including feeding, sleep-metabolism interactions, state-dependent memory formation, as well as modulation of gustatory sensitivity and nociception. The 22 neurosecretory cells (ABLKs) of the abdominal neuromeres coexpress LK and a diuretic hormone (DH44), and together these regulate water and ion homeostasis and associated stress, as well as food intake. In Drosophila larvae, LK neurons modulate locomotion, escape responses, and aspects of ecdysis behavior. A set of lateral neurosecretory cells, ALKs, in the brain express LK in larvae, but inconsistently so in adults. These ALKs coexpress three other neuropeptides and regulate water and ion homeostasis, feeding and drinking, but the specific role of LK is not yet known. This review summarizes Drosophila data on embryonic lineages of LK neurons, functional roles of individual LK neuron types, interactions with other peptidergic systems, and orchestrating functions of LK.
Surveillance of U.S. Corporate Filings Provides a Proactive Approach to Inform Tobacco Regulatory Research Strategy
Authors: Sarles S. Emma , Hensel Edward C. , Robinson Risa J.
Published: January 2021

The popularity of electronic cigarettes in the United States and around the world has led to a startling rise in youth nicotine use. The Juul e-cigarette was introduced in the U.S. market in 2015 and had captured approximately 13% of the U.S. market by 2017. Unlike many other contemporary electronic cigarette companies, the founders behind the Juul® e-cigarette approached their product launch like a traditional high-tech start-up company, not like a tobacco company. This article presents a case study of Juul’s corporate and product development history in the context of US regulatory actions. The objective of this article is to demonstrate the value of government-curated archives as leading indicators which can (a) provide insight into emergent technologies and (b) inform emergent regulatory science research questions. A variety of sources were used to gather data about the Juul e-cigarette and the corporations that surround it. Sources included government agencies, published academic literature, non-profit organizations, corporate and retail websites, and the popular press. Data was disambiguated, authenticated, and categorized prior to being placed on a timeline of events. A timeline of four significant milestones, nineteen corporate filings and events, twelve US regulatory actions, sixty four patent applications, eighty seven trademark applications, twenty three design patents and thirty two utility patents related to Juul Labs and its associates is presented spanning the years 2004 thought 2020. This work demonstrates the probative value of findings from patent, trademark, and SEC filing literature in establishing a premise for emergent regulatory science research questions which may not yet be supported by traditional archival research literature. The methods presented here can be used to identify key aspects of emerging technologies before products actually enter the market, this shifting policy formulation and problem identification from a paradigm of being reactive in favor of becoming proactive. Such a proactive approach may permit anticipatory regulatory science research and ultimately shorten the elapsed time between market technology innovation and regulatory response.
Co-Gasification of Biomass and Coal: Overview, Challenges and Recommendations
Authors: Shahabuddin M. , Bhattacharya Sankar
Published: January 2021

Co-gasification of biomass and coal is a promising technique to improve gasification performance besides reducing emission from individual gasification of coal. In this review, the current status of co-gasification, including challenges and possible solutions are discussed. It is found that co-gasification improves carbon conversion, syngas quality and heating value while reducing the slagging temperature and pollutants emission. The higher reactivity of co-gasification is the results of synergistic effect due to dominant alkali and alkaline earth materials (AAEM) present in biomass ash. The co-gasification challenges include non-uniform particle size of biomass, inhomogeneous mixing of particles, the temperature difference between coal and biomass particles, and the higher moisture content in biomass and agglomeration. However, these challenges can be mitigated by torrefaction of biomass using waste energy and optimum blending ratio.

In the present study, fish were exposed to sub-lethal doses of CuONPs (68.92 ± 3.49 nm) (10, 20, and 50 mg/L) for a long exposure period (25 days). Compared to the control group (0.0 mg/L CuONPs), a significant dose-dependent elevation in blood urea and creatinine values, serum alanine transaminase, aspartate transaminase, and alkaline phosphatase enzyme activities were evident in CuONPs-exposed groups (P < 0.05). Fish exposure to 50 mg/L CuONPs significantly upregulated the transcription of pro-inflammatory cytokines (tumor necrosis factor-alpha, interleukin-1beta, interleukin 12, and interleukin 8), heat shock protein 70, apoptosis-related gene (caspase 3), and oxidative stress-related (superoxide dismutase, catalase, and glutathione peroxidase) genes in liver and gills of the exposed fish in comparison with those in the control group (P < 0.05). Moreover, varying histopathological injuries were noticed in the hepatopancreatic tissues, posterior kidneys, and gills of fish groups correlated to the examined exposure dose of CuONPs. In summary, our results provide new insights and helpful information for better understanding the mechanisms of CuONPs toxicity in Nile tilapia at hematological, molecular levels, and tissue levels.
The Photochemistry of Fe2(S2C3H6)(CO)6(µ-CO) and its Oxidized Form, Two Simple [FeFe]-Hydrogenase CO-Inhibited Models. A DFT and TDDFT Investigation
Authors: Arrigoni Federica , Zampella Giuseppe , De Gioia Luca , Greco Claudio , Bertini Luca
Published: January 2021

FeIFeI Fe2(S2C3H6)(CO)6(µ-CO) (1a-CO) and its FeIFeII cationic species (2a+-CO) are the simplest model of the CO-inhibited [FeFe] hydrogenase active site, which is known to undergo CO photolysis within a temperature- dependent process whose products and mechanism are still a matter of debate. Using Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TDDFT) computations, the ground state and low-lying excited state potential energy surfaces (PESs) of 1a-CO and 2a+-CO have been explored aimed at elucidating the dynamics of the CO photolysis yielding Fe2(S2C3H6)(CO)6 (1a) and Fe2(S2C3H6)(CO)6+ (2a+), two simple models of the catalytic site of the enzyme. Two main results came out from these investigations. First, a-CO and 2a+-CO are both bound with respect to any CO dissociation with lowest free energy barriers around 10 kcal mol-1, suggesting that at least 2a+-CO might be synthetized. Second, focusing on the cationic form, we found at least two clear excited state channels along the PESs of 2a+-CO that are unbound with respect to equatorial CO dissociation.

Published: January 2021

Annually, millions of people (including children) across the world face minor to severe impact from natural or human-induced disasters. Diverse models have been conceptualized and adopted at global scale to increase resiliency of children from disasters focusing on preparedness, response and recover. As children spend most of their lives at school or at home, this paper discusses on factors contributing towards improving or degrading resiliency of children from disasters. Giving low priority to institutional resilience, this paper highlights the behavioral aspects of children which becomes their strength on demonstrating appropriate practices to mitigate disaster risks on self at school, home and community. While doing so, attributes from Ajzen’s Theory of Planned Behavior has been linked with the components of resilience to explain the causative factors. Adopting desk review, this paper describes behavioral attributes of children and emphasizes on need of having multi-dimensional framework to enhance resiliency of children.

Authors: Thapa Manish
Published: January 2021

Statistical management policy and system plays significant role in development of any nation as it guides the planner to analyze the gaps, design programs and allocate budget in efficient manner. Globally, design and usage of statistical management system varies relying on country specific ability and resources availability. Government of Nepal has been managing database in individual as well as thematic manner. Policy wise, thematic database is in operation based on Statistics Act 1958 and individual database is in operation based on Birth, Death and Other Personal Related Events Registration Act 1976. Though civil registration related policies have been either updated or newly formed, sectoral statistic management related policy has not been updated since its first promulgation period (1958). With no policy supporting the consolidated statistical management system, government as well as non-government agencies has been investing millions of dollars annually to collect, compile and analyze individual related data and fulfill their respective objectives. It has forced the government services and performance to be paper-based, time-consuming and tedious thus creating dis-trust among citizen each passing day. Though, formulation of legal instrument promoted digital movement and mandated shift towards e-government modality, the process has been low. Theoretically, Technology Acceptance Model (TAM) state the need of having advanced and efficient technology to be in place in current setting to improve governance, efficiency, accountability, transparency and trust. Also, the same theory state the requirement of strong willingness and motivation from the users (government, non-government and citizen) to adopt the technology based policy and system. As the integrated statistical management policy emphasizes on technology-based system or digital system, the perspectives of Technology Acceptance Model also termed as Information System Theory aid in understanding the context, conceptualizing and addressing the needs with an establishment and implementation of digital system or technology based system. This policy paper applied the Technology Acceptance Model (TAP) to examine the underlying opportunities and challenges associated with an integrated statistical management policy. With existing gaps in existing policy, system and practice alongside an overview of opportunities and challenges, this paper recommends the need of stand-alone integrated statistical management policy to consolidate sectoral as well as civil related information through single system based on recommended policy.

Background: It is unknown whether prolonged artificial hormonal environment during early fetal development affects the birthweight of singletons born after frozen-thawed embryo transfer (FET). Methods: A retrospective observational study included singleton births>22 weeks of gestation obtained after FET between 2013-2019 after endometrial preparation with ovulatory cycle (OC) or artificial cycle (AC). Our primary objective was to compare birthweight of singletons after FET between endometrial preparation by OC or AC. Secondary objectives included prolonged pregnancies, high birthweight, low birthweight, SGA and LGA rates. Multivariate analyses were performed considering potential confounding factors. Results: Among 198 singleton live births after FET, 112 were obtained with OC and 86 with AC. Prolonged pregnancies rate was higher in AC (25.6% vs. 7.1%, respectively, p=0.001). Mean birthweight was higher (+219g) in AC (3386g vs. 3167g, p=0.01; adjusted-p=0.052), as well as the rate of babies exceeding 4000g (16.3% vs. 2.7%, p=0.03, adjusted-p=0.015). The rate of babies <2500g was lower in AC (3.5% vs. 11.6%, respectively, p=0.050, adjusted-p=0.049). Conclusions: Since OC does not strain the chances of pregnancy and in the incomplete knowledge of the consequences of neonatal overweight on the future health of children, OC preparation could be advocated as first-line endometrial preparation in FET.
Eﬀects of Uniform Rotation and Cornell-Type Potential on KG-Scalar Particle in Kaluza-Klein Theory
Authors: Ahmed Faizuddin
Published: January 2021

The non-inertial eﬀects on spin-0 scalar particle that interacts with scalar potentials of Cornell-type in cylindrical system and Coulomb-type in the magnetic cosmic string space-time using Kaluza-Klein theory is analyzed. We show that the energy eigenvalue and eigenfunction depend on the global parameters characterizing the space-time, and the gravitational analogue of the Aharonov-Bohm eﬀect for bound states is observed.
Kerentanan Perbankan di Indonesia: Pengukuran dan Penyebabnya
Authors: Wibowo Wisnu , Zakaria Amir Ambyah
Published: January 2021

This study aims to identify banking vulnerabilities and analyze the factors that influence them. The tool used to identify bank vulnerabilities uses modification crisis and default index (C&D Index) while hypothesis testing uses logit regression. Commercial banks in Indonesia from 2008 to 2018 was taken as sample. As a result, in 2008 and 2013 were the most vulnerable conditions for banks in Indonesia. The reason most banks have been identified as vulnerable is due to decreased profits, increased liabilities in foreign currencies and increased Non Performing Loan (NPL). Logit regression test show that banking fragility is negatively related to capital, liquid assets, and financial assets. ------------------------------ Penelitian ini bertujuan untuk mengidentifikasi kerentanan perbankan dan menguji faktor yang diduga memengaruhinya. Kerentanan bank diidentifikasi menggunakan modifikasi crisis and default index (C&D Index), sedangkan pengujian hipotesis menggunakan regresi logit. Sampel penelitian ini adalah 27 bank komersil di Indonesia periode 2008 sampai 2018. Hasilnya, tahun 2008 dan 2013 adalah kondisi yang paling rentan bagi perbankan di Indonesia. Penyebab sebagian besar bank teridentifikasi rentan adalah karena penurunan profit, peningkatan pinjaman dalam mata uang asing, dan peningkatan Non Performing Loan (NPL). Hasil uji regresi logit menunjukkan kerentanan perbankan di Indonesia berhubungan negatif dengan permodalan bank, aset likuid bank, dan aset keuangan bank.

Published: January 2021

Background:

Evidence on recent trends regarding the impact and cost-benefits of ultrasound in resource-constrained settings is limited. This study presents a systematic review to determine recent trends in the utility and applicability of ultrasound use in low and middle income countries (LMIC). The review includes characterizing and evaluating trends in (1) the geographic and specialty specific use of ultrasound in LMICs, (2) the innovative applications and the accompanying research findings, and (3) the development of associated educational and training programs.

Methods: The electronic databases Medline OVID, EMBASE, and Cochrane were searched from 2010 to 2018 for studies available in English, French, and Spanish. Commentaries, opinion articles, reviews and book chapters were excluded. Two categories were created, one for reported applications of ultrasound use in LMICs and another for novel ultrasound studies.

Results: A total of 6,276 articles were identified and screened, 4,563 studies were included for final review. 287 studies contained original or novel applications of ultrasound use in LMICs. Nearly 70% of studies involved ultrasound usage originating from Southeast Asia and sub-Saharan Africa, the latter being the region with the highest number of innovative ultrasound use. Educational studies, global collaborations, and funded studies were a substantial subset of overall ultrasound research. Our findings are limited by the lack of higher quality evidence and limited number of randomized clinical trials reported.

Conclusion/Global Health Implications: Our systematic literature review of ultrasound use in LMICs demonstrates the growing utilization of this relatively low-cost, portable imaging technology in low resource settings.

Key words: • Ultrasound • Ultrasono graph y • Echocardiogram • LMIC • Low resource • Global health • Systematic review

Characteristics of Early Newborn Care: A Descriptive Analysis of Recent Births in Nigeria
Authors: Olorunsaiye Comfort Z. , Harris A-Mac , Yusuf Korede K.
Published: January 2021

Background or Objectives: The neonatal period, the first 28 days of life, is the most critical period for child survival. In 2017, 214,000 children in Nigeria died during the neonatal period. Newborn care practices play a key role in preventing these deaths. The aim of this study was to examine the association between delivery location and early newborn care in Nigeria.

Methods: Data from the 2013 Nigeria Demographic and Health Survey were analyzed. The main exposure variable was delivery location (home, public hospital, public health center/clinic and private hospital/clinic). The outcomes were early initiation of breastfeeding, breastfeeding support, and cord examination. We used multivariate logistic regression to estimate the odds of newborn care.

Results: We observed that the prevalence of all three outcome indicators was low. After adjusting for confounders, birth in public health facilities, compared to home birth, was associated with early initiation of breastfeeding (public hospitals: OR 1.62, 95% CI: 1.29-2.03; public health centers/clinics OR: 1.28, 95% CI: 1.02-1.61). Breastfeeding support and cord examination were each associated with birth in public hospitals only compared to home birth (OR 1.41, 95% CI: 1.09-1.81 and OR 1.41, 95% CI: 1.11-1.79, respectively).

Conclusion and Global Health Implications: Early newborn care in Nigeria was suboptimal and the quality of this care varied across delivery locations and birth attendants. Public hospitals had the most favorable newborn care outcomes. Policies and programs to enhance the quality of facility-based early newborn care and promote community-based newborn care could improve neonatal outcomes and reduce overall child mortality in resource-challenged settings.

Key words: • Newborn care • Neonatal mortality • Breastfeeding • Cord care • Nigeria
