The Influence of Social Class on Family Participation in Children’s Education: A Case Study
Authors: Vazquez Salvador R. , Greenfield Patricia M. 
Published: March 2021

Parental involvement in children’s education is commonly accepted as beneficial. However, family social class plays a crucial role in the efficacy of homework help. In a comparative case study, a low-income immigrant family from Mexico and a middle-income family in Los Angeles were observed helping their children with math homework and were asked questions about goals, tutoring strategies, and beliefs about learning. Qualitative analysis focused on two effective teaching methods: scaffolding and productive struggle. The low-income mother with little formal education provided direct help rather than a scaffold, and disapproved of hard problems. However, an older sibling with more education than her mother used scaffolding and believed that difficult problems aid learning. In these respects, she resembled the college-educated middle-income mother. The sister exemplifies how older siblings in immigrant families provide bridges to educational achievement for younger siblings. We suggest effective ways for schools to involve parents who lacked educational opportunity themselves to participate in the education of their children.

Introduction: While our knowledge is limited about COVID-19 immunity, recent cases of reinfection have raised concerns.
Case presentation: Here, we report a case of COVID-19 reinfection after three months from recovery in a healthcare worker with negative IgM and IgG at the second infection and positive nasopharyngeal swab Reverse transcription polymerase chain reaction (RT-PCR) test despite being discharged with two negative RT-PCR tests at the first admission. Symptoms at first admission were fever, headache, sore throat, diarrhea, and vomiting and got changed to myalgia and anosmia.
Conclusion: The strength of this case report is the long period (three months) between the infection and reinfection while other cases reported in literature were reinfected less than one month after their first infection.

Abstrak - Koperasi merupakan suatu lembaga atau organisasi dalam melakukan simpan pinjam berupa uang dan barang supaya bisa mensejahterakan anggota koperasi tersebut namun dari hasil wawancara dengan ketua koperasi SMKN 1 Kota Bima ternyata masih banyak sebagian dari anggota koperasi yang tidak mebayar pinjaman ataupun tagihan kredit secara kontinyu sesuai dengan perjanjian kredit hal ini akan berdampak pada kondisi keuangan koperasi untuk pemberian kredit berikutnya kepada anggotanya, sehingga dalam Penelitian ini bertujuan untuk mengetahui seberapa besar kredit macet pada koperasi SMKN 1 Kota Bima untuk periode 2014-2019. Adapun sampel dalam penelitian ini penulis menggunakan laporan keuangan 6 tahun terakhir yaitu dari periode 2014-2019. Data yang digunakan dalam penelitian ini adalah dengan menggunakan data laporan keuangan berupa data kredit macet dan total kredit yang diberikan,data yang digunakan adalah data sekunder dan metode yang digunakan yaitu uji t one sample (uji 1 pihak). Dimana koperasi SMKN 1 Kota Bima ini belum bisa dikatakan baik karena Non Performing Loan (NPL) pada tahun 2015 sebesar 2,72, 2016 sebesar 1,41 , 2017 sebesar 0,75 dan 2019 sebesar 0,59 karena NPL yang baik itu sesuai dengan krireria yaitu harus kurang dari 0,05 atau 5% dari kriteria yang diharapkan hal serupa juga terlihat dari perolehan nilai kredit macet pada tahun 2015 sampai dengan 2019 mengalami fluktiatif hal ini disebabkan karena banyaknya dari sebagain anggota koperasi yang tidak membayar angsuran kredit secara tepat waktu padahal dikontrak perjanjian kredit sudah tertera jelas bahwa anggota akan memebayar kredit sesuai dengan keputusan yang telah disepakati bersama.

Published: March 2021

Abstract
Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths in Africa. In Africa, the major causes of HCC include chronic infection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV). Knowledge of the changes in the incidence of viral hepatitis-associated HCC over time and the factors responsible for such changes is key in informing policies for the prevention of viral hepatitis-associated HCC in Africa. Aim: The study aimed to systematically summarize the changes in the incidence of viral hepatitis-associated HCC in Africa over a four-decade period (1980-2020).Methods: A literature search was conducted in MEDLINE (PubMed), Google Scholar, Science Direct, Scopus, Web of Science, and African wide web for articles published on viral hepatitis-associated HCC in Africa from 1980-2020. The abstracts of the articles were screened for eligibility and those meeting the inclusion criteria were retrieved and reviewed.Results: A total of 272 studies were included in the analysis. Viral hepatitis-related HCC incidence changed by 1.17% (95% confidence interval (CI): 0.63 – 1.71, p < 0.001), 0.82% (95% CI: 0.45 – 1.18, p < 0.001), and 3.34% (95% CI: 2.44 – 4.25, p < 0.001) for every 1% change in the prevalence of HBV, HCV, and hepatitis D virus (HDV) respectively, per decade. The incidence of HBV-related HCC changed significantly by -0.50% (95% CI: -0.74 – -0.25, p < 0.001) over the last 40 years, while HCV-related HCC increased.Conclusion: Overall, the incidence of viral hepatitis-associated HCC has not declined, mainly due to no decline in the prevalence of HCV, HDV, and the high number of chronic hepatitis B carriers on the African continent. There is an urgent need for the allocation of resources for the implementation of treatment and preventive programs for HBV, HCV, HDV, and HCC in Africa.This systematic review is registered with PROSPERO®, number CRD42020169723.
The influence of Conditioned Stimuli on [11C]-(+)-PHNO PET Binding in Tobacco Smokers after a One Week Abstinence

Abstract
Stimuli previously paired with drugs of dependence can produce cravings that are associated with increased dopamine (DA) levels in limbic and striatal brain areas. Positron Emission Tomography (PET) imaging with [11C]-(+)-PHNO allows for a sensitive measurement of changes in DA levels. The purpose of the present study was to investigate changes in DA levels, measured with PET imaging with [11C]-(+)-PHNO, in regions of interest in smokers who had maintained abstinence for 7-10 days. Participants (N=10) underwent two PET scans on separate days, during which they viewed either smoking-related or neutral images, in counterbalanced order. Craving was measured with the 12-item Tobacco Craving Questionnaire (TCQ) and the Questionnaire on Smoking Urges-Brief (QSU-B). Compared to neutral cues, smoking cues did not increase craving. There were no changes in [11C]-(+)-PHNO binding in the cue condition compared to the neutral condition for most regions of interest (ventral pallidum, globus pallidus, limbic striatum, associative striatum, sensorimotor striatum). However, binding potential in the substantia nigra was greater in the smoking-cue condition, indicating decreased synaptic dopamine. There is a potential change of DA level occurring in midbrain following the presentation of smoking-related cues.

Published: March 2021

Abstract
BackgroundGlobally, over half of maternal deaths are related to pregnancy-related complications. Provision of a continuum of care during pregnancy, childbirth and the postnatal period results in reduced maternal and neonatal morbidity and mortality. Hence this study determined the prevalence of the continuum of care and its determinants among women in Zambia.MethodsWe used weighted data from the Zambian Demographic and Health Survey (ZDHS) of 2018 for 7325 women aged 15 to 49 years. Multistage stratified sampling was used to select study participants. We conducted multivariable logistic regression to explore continuum of care in Zambia. All our analyses were done using SPSS version 25. ResultsOf the 7,325 women, 38.0% (2787/7325) (95% CI: 36.9-39.1) had complete continuum of maternal healthcare (four and more antenatal care contacts, childbirth at a health facility and postnatal care). Women who had attained tertiary level of education (AOR: 1.84, 95% CI: 1.01-3.35) and whose partners had also attained tertiary level of education (AOR: 2.54, 95% CI: 1.52-4.27) were more likely to utilize the whole continuum of care compared to those who had no education. Women who initiated antenatal care (ANC) after the first trimester (AOR: 0.46, 95% CI: 0.39-0.53) were less likely to utilize the whole continuum of care compared to those who initiated in the first semester. Women with exposure to radio (AOR: 1.58, 95% CI: 1.28-1.96) were more likely to utilize the whole continuum of care compared to those who were not exposed to radio. Women residing in the Western province were less likely to utilize the entire continuum of care compared to those in the other nine provinces.ConclusionLevel of education of the women and of their partners, early timing of ANC initiation, residing in other provinces other than the Western province, and exposure to information through radio were positively associated with utilization of the entire continuum of care. Improving literacy levels and promoting maternity services through radio may improve the level of utilization of maternity services.

Abstract
The ‘Gülzow’ (G) type cytoplasmic male sterility (CMS) system in hybrid rye (Secale cereale L.) breeding exhibits a strong and environmentally stable restoration of male fertility (Rf). While having received little scientific attention, three G-type Rf genes had been identified on 4RL (Rfg1) and two minor genes on 3R (Rfg2) and 6R (Rfg3) chromosome. Here, we report a comprehensive investigation of the genetics underlying restoration of male fertility in a large G-type CMS breeding system using a palette of complementing forward and reverse genetic analysis. This includes (i) genome wide association studies (GWAS) on a G-type germplasm, (ii) GWAS on a biparental mapping population, (iii) in silico identification of Rf-like pentatricopeptide repeat (RFL-PPR) genes and their expressed in G-type rye hybrids, and (iv) mining patterns in linkage disequilibrium. Our findings provide compelling evidence of a novel major G-type non-PPR Rf gene on the 3RL chromosome. In the in silico analysis, we identified 22 RFL-PPR of which 15 were expressed in the transcriptome of G-type hybrids. Our findings provides a novel insight into the underlying genetics of male fertility restoration in a G-type CMS system in rye. The discovery made in this study is distinct to known P- and C-type systems in rye in addition to known CMS systems in barley and wheat. This study constitutes a steppingstone towards understanding the restoration of male fertility in G-type CMS system and a potential resources for addressing the inherent issues of the P-type system.

Abstract
This study reports the Length-weight relationships (LWRs) of three freshwater eel species from the northeastern wetlands of Bangladesh. A total of 2684 specimens of Mastacembelus armatus, Macrognathus aculeatus and Macrongathus pancalus were sampled between in the months of June and December 2019 using different nets and eel traps at every 4 days working schedule per month. The calculated a values of the LWRs ranged from 0.008 to 0.020; b values ranged from 2.35 to 2.70, and r2 from 0.907 to 0.944. The lowest values of regression coefficient found for M. aculeatus and the highest for M. pancalus. All the regression parameters for LWRs found highly significant (p ˂ 0.001). These results will provide baseline information for sustainable management and conservation of the fisheries resources in the northeastern floodplain region of Bangladesh.

Abstract
The influences of influent surface organic loading rate (SOLR) and aeration mode on matrix oxygen, organic matter, nitrogen, phosphorus removal, greenhouse gases emission and functional gene abundances in lab-scale wastewater ecological soil infiltration systems (WESISs) were investigated. In WESISs, intermittent or continuous aeration improved oxygen supply at 50 cm depth and hardly changed anaerobic condition below 80 cm depth, which enhanced chemical oxygen demand (COD), NH4+-N, total nitrogen (TN) removal, the abundances of bacterial 16S rRNA, amoA, nxrA, narG, napA, nirK, nirS, qnorB, nosZ genes and reduced CH4, N2O conversion efficiencies with SOLR of 16.9 and 27.6 g BOD/(m2 d) compared with non-aeration. Increased SOLR resulted in high TN removal, low N2O emission in aeration WESIS, which was different from non-aeration WESIS. High average COD removal efficiency of 90.7%, NH4+-N removal efficiency of 87.0%, TN removal efficiency of 84.6%, total phosphorus (TP) removal efficiency of 93.1% and low average N2O emission rate of 12.8 mg/(m2 d) were achieved with SOLR of 16.9 g BOD/(m2 d) in intermittent aeration WESIS. However, continuous aeration WESIS obtained high average removal efficiencies of 90.1% for COD, 87.5% for NH4+-N, 84.1% for TN, 92.9% for TP and low average emission rate of 13.1 mg/(m2 d) for N2O with SOLR of 27.6 g BOD/(m2 d). Aeration could be an optional strategy for WESISs to achieve high pollutants removal and low CH4, N2O emission when treating wastewater with high SOLR.
