Vocabulary Depth and Language Use of Heritage Learners

Persons whose home environment features a non-majority language are known as heritage speakers. The nature and conditions of Spanish heritage speakers’ interaction with their heritage language significantly affects their command of it. The aim of this study is to explore vocabulary depth among 10-year-old heritage language speakers in Springfield, Missouri, and its relationship to language use at home. This study adds to the body of knowledge related to heritage language development by exploring language use at home and church activities, as well as vocabulary depth in Spanish heritage speakers in the Springfield metropolitan area by investigating social and linguistic aspects of Spanish heritage speakers, the use of Spanish at home and at church activities and how this affects the vocabulary depth of children. Oral surveys were conducted with the parents of the children and with the children themselves. The children’s language depth was explored using a vocabulary depth measure. The study was not able to demonstrate the expected correlation between vocabulary depth and language use at home. The results of this study indicate that further investigation is needed to ascertain the relationship between language use in the home and vocabulary depth among Spanish heritage speakers in the Springfield, Missouri, metropolitan area

Cost Volume Profit analysis can make it easier for companies to determine revenue targets and the amount of costs incurred in an effort to achieve profit targets. This analysis has several components of analysis including contribution margin, break even point, margin of safety and operating leverage, shut down point and profit target analysis. The purpose of this study is to determine the profit planning at PT. Air Manado by using Cost-Volume-Profit analysis. The research method used is descriptive method. Based on the results of this study it is known that the cost profit volume analysis for the profit planning in 2022 showed that Cousin Coffee & Eatery was able to cover its fixed costs and earn a profit with a contribution margin of Rp333,976,953 or 77%. Cousin Coffee & Eatery is at breakeven point of Rp31,969,264 if it is able to reach a sales volume of Rp429,773,456. While the margin of safety, sales can decline so as not to cause losses is Rp397,804,192 or 92.56%. Then for operating leverage shows the number 1.08. Furthermore, the shut down point for profit planning of 2022 Cousin Coffee & Eatery in 2022 is at its closing point of Rp31,969,264 which means Cousin Coffee & Eatery must generate sales above that amount in order to finance its cash costs. To get a 50% increase in profit or profit of Rp309,360,620, Cousin Coffee & Eatery must increase sales by Rp429,773,456. Variable costs will also increase following the increase in production costs, while fixed costs are assumed to be constant or unchanged

Aberrant right subclavian artery in a cadaver: a case report of an aortic arch anomaly

In early embryogenesis, aortic anomalies occur as a consequence of disorders in the development of the primitive aortic arches system. Aberrant right subclavian artery, also known as arteria lusoria, is one of the important congenital anomalies of the aortic arch, in which the right subclavian artery arises from the arch of aorta instead of the brachiocephalic trunk. During routine dissection of a female cadaver, we observed retro-oesophageal aberrant right subclavian artery arising as the fourth branch from the aortic arch. In this case, the brachiocephalic trunk was absent. Early detection of aortic arch anomalies through diagnostic interventions is helpful to avoid complications during surgical procedures

Responding to the COVID-19 Pandemic in Cameroon: A statement from the Cameroon Bioethics Initiative

The ongoing COVID-19 pandemic has caused devastating consequences across economies in the world, with substantial effects on lives and livelihoods. Cameroon has been one of the countries in sub-Saharan Africa with an increasing number of cases and fatalities from the disease. In an effort to support the government’s response to the epidemic, the Cameroon Bioethics Initiative (CAMBIN); a not-for-profit, non-governmental, non-political, non-discriminatory, multidisciplinary association issued a statement on COVID-19, primarily targeting the government and the general public. In this article, we situate the context within which the statement was issued and present the statement in its entirety

The UALE project : a cross-sectional approach for trends in HIV/STI prevalence among key populations attending STI clinics in Guatemala

To describe and compare trends in prevalence, sexual behaviour and HIV transmission knowledge data related to sexually transmitted infections (STI) and HIV in patients attending three STI clinics over an 8-year period in Escuintla Department, Guatemala. STI clinic attendees were classified into transmission groups as follows: female sex workers (FSW), men who have sex with men (MSM) and 'high-risk heterosexuals' (HRH). Annual cross-sectional analysis and multivariable Poisson regression adjusted for sociodemographic variables were used for prevalence comparisons and adjusted prevalence trends for HIV/STI outcomes and used for adjusted trends in proportions in sexual behaviour and HIV transmission knowledge outcomes. Endocervical swabs were obtained to detect trichomonas, chlamydia and neisseria infections. Serologies for syphilis and HIV were performed using rapid tests. For reactive HIV samples, positivity was confirmed by an ELISA. All reactive syphilis samples were further confirmed for diagnosis of active syphilis disease. From a total of 4027 clinic attendees, 3213 (79.78%) were FSW, 229 (5.69%) were MSM and 585 (14.53%) were HRH. The proportion of FSW, MSM and HRH who had a single visit was 56.42%, 57.23% and 91.10%, respectively. Overall, HIV prevalence was 2.10% in FSW, 8.17% in MSM and 4.12% in HRH. Prevalence trends in HIV and syphilis decreased in FSW. Prevalence trends in gonorrhoea did not decrease over time neither in FSW nor in HRH. Chlamydia and trichomonas infections in HRH showed an increase prevalence trend. In FSW, trends in condom use in last sexual intercourse with regular and occasional clients were above 93%. FSW show a decreasing trend in HIV, syphilis and chlamydia prevalence. Gonorrhoea prevalence in FSW and HRH did not decrease over time. HRH is a hard to engage population with low follow-up rates and high potential to act as a bridge population

ANIMAL MODELS FOR THE STUDY OF LEISHMANIASIS IMMUNOLOGY

Leishmaniasis remains a major public health problem worldwide and is classified as Category I by the TDR/WHO, mainly due to the absence of control. Many experimental models like rodents, dogs and monkeys have been developed, each with specific features, in order to characterize the immune response to Leishmania species, but none reproduces the pathology observed in human disease. Conflicting data may arise in part because different parasite strains or species are being examined, different tissue targets (mice footpad, ear, or base of tail) are being infected, and different numbers (“low” 1×102 and “high” 1×106) of metacyclic promastigotes have been inoculated. Recently, new approaches have been proposed to provide more meaningful data regarding the host response and pathogenesis that parallels human disease. The use of sand fly saliva and low numbers of parasites in experimental infections has led to mimic natural transmission and find new molecules and immune mechanisms which should be considered when designing vaccines and control strategies. Moreover, the use of wild rodents as experimental models has been proposed as a good alternative for studying the host-pathogen relationships and for testing candidate vaccines. To date, using natural reservoirs to study Leishmania infection has been challenging because immunologic reagents for use in wild rodents are lacking. This review discusses the principal immunological findings against Leishmania infection in different animal models highlighting the importance of using experimental conditions similar to natural transmission and reservoir species as experimental models to study the immunopathology of the disease

Functional analysis of the EGF-like domain mutations Pro55Ser and Pro55Leu, which cause mild hemophilia B.

We studied the functional role of two mutations, Pro55Ser and Pro55Leu, located in the N-terminal Epidermal Growth Factor-like domain (EGF1) of coagulation factor (F) IX. Both mutations cause mild hemophilia B with habitual FIX coagulant activities of 10-12% and FIX antigen levels of 50%. We found that activation by FVIIa/TF and FXIa was normal for FIXPro55Ser, but resulted in proteolysis of FIXPro55Leu at Arg318-Ser319 with a concomitant loss of amidolytic activity, suggesting intramolecular communication between EGF1 and the serine protease domain in FIX. This was further supported by experiments using an anti-EGF1 monoclonal antibody. Activation of FX by FIXaPro55Ser was impaired in both the presence and the absence of phospholipid or FVIIIa, indicating that Pro55 is not directly involved in binding to FVIIIa. We also studied the effect of the two Pro55 mutations on Ca2+ affinity and found only small changes. Thus, the Pro55Ser mutation causes hemophilia primarily through to an impaired ability to activate FX whereas at least in vitro the Pro55Leu defect interferes with the activation of FIX
