AbstractNovel corona virus is declared as pandemic and India is struggling to control this from a massive attack of death and destruction, similar to the other countries like China, Europe, and the United States of America. India reported 2545 cases novel corona confirmed cases as of April 2, 2020 and out of which 191 cases were reported recovered and 72 deaths occurred. The first case of novel corona is reported in India on January 30, 2020. The growth in the initial phase is following exponential. In this study an attempt has been made to model the spread of novel corona infection. For this purpose logistic growth model with minor modification is used and the model is applied on truncated information on novel corona confirmed cases in India. The result is very exiting that till date predicted number of confirmed corona positive cases is very close to observed on. The time of point of inflexion is found in the end of the April, 2020 means after that the increasing growth will start decline and there will be no new case in India by the end of July, 2020.

Curve Modeling

AbstractIn this paper, we investigate briefly the appropriateness of the widely used logistic growth curve modeling with focus on COVID-19 spread, from a data-driven perspective. Specifically, we suggest the Gumbel growth model for behaviour of COVID-19 cases in European countries in addition to the United States of America (US), for better detecting the growth and prediction. We provide a suitable fit and predict the growth of cases for some selected countries as illustration. Our contribution will stimulate the correct growth spread modeling for this pandemic outbreak.

Stock Market Returns

Stock markets over the world have become more interconnected due to activities of foreign investors in search for alternative financial assets and markets to invest in order to diversify their portfolio. Stock market indices and index returns have been known to reflect linkages between different markets. This study assesses the extent of correlation of stock market index returns in West Africa and those of the United States of America (US) and United Kingdom (UK) from 2008 to 2016. The correlation between the index returns for the entire sample period and yearly samples were considered for Nigeria, Ghana, the BRVM, the USA and the UK. The indices selected for the five countries considered are the Nigerian All-Share Index, Ghanaian Composite Index, the BRVM Composite Index, the Financial Times 100 Index and the Standards and Poor’s 500 Index. Daily index returns data were used for the study and analyzed using correlation and multiple regression analysis. Findings revealed that the returns of the pairs of the United States of America (US) and the United Kingdom (UK) exhibited stronger positive correlation with each other than the other market pairs in the study both in the entire sample period and the yearly sub-period analysis. The correlations between the other market pairs were either positively or negatively weak or very weak indicating more diversification opportunities.

Belize has one of the highest homicide rates in the world; however, the gangs at the heart of this violence have rarely been studied. Using a masculinities lens and original empirical data, this article explores how Blood and Crip “gang transnationalism” from the United States of America flourished in Belize City. Gang transnationalism is understood as a “transnational masculinity” that makes cultural connections between local settings of urban exclusion. On one hand, social terrains in Belize City generated masculine vulnerabilities to the foreign gang as an identity package with the power to reconfigure positions of subordination; on the other, the establishment of male gang practices with a distinct hegemonic shape, galvanized violence and a patriarchy of the streets in already marginalized communities. This article adds a new body of work on gangs in Belize, and gang transnationalism, whilst contributing to theoretical discussions around the global to local dynamics of hegemonic masculinities discussed by Connell and Messerschmidt (2005) and Messerschmidt (2018).

AbstractZika virus is increasingly recognized as a fetal pathogen worldwide. We describe the first case of neonatal demise with travel-associated Zika virus infection in the United States of America, including a novel prenatal ultrasound finding. A young Latina presented to our health care system in Southeast Texas for prenatal care at 23 weeks of gestation. Fetal Dandy–Walker malformation, asymmetric cerebral ventriculomegaly, single umbilical artery, hypoechoic fetal knee, dorsal foot edema, and mild polyhydramnios were noted upon initial screening prenatal sonography at 26 weeks. A growth-restricted, microcephalic, and arthrogrypotic infant was delivered alive at 36 weeks but died within an hour despite resuscitation. The neonatal karyotype was normal. Flavivirus IgM antibodies were identified in the serum of the puerpera, once she disclosed that she had traveled from El Salvador to Texas in the early second trimester. Zika virus was identified in the umbilical cord and neonatal brain. Fetal arthritis may precede congenital arthrogryposis in cases of Zika virus infection and may be detectable by prenatal sonography. Physician and health care system vigilance is required to optimally address the significant and enduring Zika virus global health threat.

The United States of America, having refused to ratify the peace treaty negotiated at Paris in 1919 between the Allied and Associated Powers, on the one hand, and Germany on the other hand, commonly called the Treaty of Versailles, has, nevertheless, reserved to itself all the rights arising from the said treaty in the separate treaty of peace which was concluded between the United States of America and Germany on August 25, 1921, and ratified at Berlin on November 11, 1921, the treaty having been promulgated by the President of the United States on November 14, 1921. The clause containing the said reservation of rights reads thatGermany undertakes to accord to the United States and the United States shall have and fully enjoy all the rights, privileges, indemnities, reparations or advantages specified in the Joint Resolution of Congress of the United States of July 2, 1921, including all the rights and advantages stipulated for the benefit of the United States in the Treaty of Versailles, notwithstanding the fact that such treaty has not been ratified by the United States, [and] the rights and advantages stipulated …are those defined in Part X…

AbstractSince the first case reported of SARS-CoV-2 the end of December 2019 in China, the number of cases quickly climbed following an exponential growth trend, demonstrating that a global pandemic is possible. As of December 3, 2020, the total number of cases reported are around 65,527,000 contagions worldwide, and 1,524,000 deaths affecting 218 countries and territories. In this scenario, Spain is one of the countries that has suffered in a hard way, the ongoing epidemic caused by the novel coronavirus SARS-CoV-2, namely COVID-19 disease. In this paper, we present the utilization of phenomenological epidemic models to characterize the two first outbreak waves of COVID-19 in Spain. The study is driven using a two-step phenomenological epidemic approach. First, we use a simple generalized growth model to fit the main parameters at the early epidemic phase; later, we apply our previous finding over a logistic growth model to that characterize both waves completely. The results show that even in the absence of accurate data series, it is possible to characterize the curves of case incidence, and even construct short-term forecast in the near time horizon.

Executive Orders are not invoked as a matter of course by the President or Governors heading the Executive Cabinet. These orders are exercisable when heads of the executive branch of government see for their needfulness and for smooth running of their governmental programmes or policies. Every Executive order must carry the force of law for it to be valid or to be duly recognised by the other branches of government which if not, the latter may question its constitutionality. The advantages of executive orders are very innumerable to mention however it has been said that the use of executive orders have assaulted the concept of separation of powers which is embedded in the 1999 Nigerian Constitution (as amended)as adopted from the United States of America. This paper focuses on the meaning and historical antecedent of executive orders in Nigeria, legal regime or statutory provisions of executive orders in Nigeria, executive orders versus doctrine of separation of power, challenges of executive orders under the 1999 constitution (as amended), praxis of executive orders under the Nigeria fourth republic and lastly is the conclusion and recommendations made thereto. To achieve these, the writers will make use of relevant materials at their disposal.

Abstract Background: Many studies have modeled and predicted the epidemic of COVID-19 in the US using data that starts from the first reported cases. However, because of the shortage of test services to detect the infected, this approach is subject to error due to under-detection in the early period of the epidemic. We attempted a new approach to overcome this limitation and to provide data supporting the public policy decisions against the life-threatening COVID-19 epidemic.Methods: Documented data by CDC were used, including daily new and cumulative cases of confirmed COVID-19 in the US from January 22 to April 6, 2020. A 5-parameter logistic growth model was used to reconstruct the epidemic. Instead of all data in the whole study period, we fitted data in a 2-week window from March 21 to April 4 (approximately one incubation period) during which massive testing services were in position. With parameters obtained from the modeling, we reconstructed and predicted the epidemic and evaluated the under-detection.Results: The data fit the model satisfactorily. The estimated daily growth rate was 16.8% (95% CI: 15.95%, 17.76%) overall, with 4 consecutive days having a doubling growth rate. Based on the modeling result, the tipping point for new cases to decline will be on April 7 th , 2020, with 32,860 new cases. By the end of the epidemic, a total of 792,548 (95% CI: 789,162-795,934) will be infected. Based on the model, a total of 12,029 cases were not detected from the first case from January 22 to April 4.Conclusions: Study findings suggest the usage of a 5-parameter logistic growth model with reliable data that comes from a specified window period, where governmental interventions are appropriately implemented. In addition to informing decision-making, this model adds one tool for use to capture the underlying COVID-19 epidemic caused by a novel pathogen.
