Hoisan-wa in Jest: Humor, Laughter, and the Construction of Counter-Hegemonic Affect in Contemporary Chinese American Language Maintenance

This research examines the language and cultural maintenance of Chinese Americans of a specific heritage: Hoisan-wa people. Hoisan-wa is one of the languages linking nearly all early Chinese immigrants in the U.S., but this language background has been pushed aside by the presence of other Chinese languages in America, such as Standard Cantonese and Mandarin. It has also been perpetually omitted from research for the last 150 years. Drawing from 93 sociolinguistic interviews with Hoisan-wa heritage people, I explore instances of humor and laughter as these participants talk about their cultural and linguistic heritage. Home and family remain two of the few domains that are consistently available to heritage language speakers, making them key foci in studying heritage language development. Unsurprisingly then, many of the humorous ways in which respondents engaged with – and commented metalinguistically about – Hoisan-wa had to do with words and phrases related to the home and family. I contend that these humorous moments serve to construct a counter-hegemonic affective stance that pushes back against established negative ideologies about Hoisan-wa, thereby creating a space to reflect and comment on language ideologies and enable speakers to adopt a language-as-resource view towards their heritage language

From Building Vocabulary to Talking about Family Traditions Together: Discussions on the Facebook Group “Hoisan Phrases 學講台山話”

This poster focuses on online discourses of an online Facebook group - “Hoisan Phrases.” “Hoisan Phrases” is used to construct positive ideologies about Hoisan-wa. Using multicompetence and symbolic competence frameworks, these online interactions are sites where Hoisan-wa speakers engage in the ability “to perform and construct various historicities in dialogue with others” (Kramsch & Whiteside). Humor serves as a way of moving beyond negative ideologies of Hoisan-wa. Data comes from a corpus of three years’ worth of posts. The data demonstrates a re-envisioning of the way we view Hoisan-wa vis-à-vis online communication, and expands the domains of language use

Neonatal jaundice in Ghanaian children: Assessing maternal knowledge, attitude, and perceptions

Background: Neonatal jaundice (NNJ) is a major cause of preventable childhood mortality and long-term impairment especially in countries with significant prevalence of the inherited condition, glucose-6-phosphate dehydrogenase (G6PD) defect. In Ghana, routine screening of pregnant women for G6PD defect is standard care. Prevention of poor health outcomes from NNJ is contingent on population health literacy and early diagnosis. As part of a project to evaluate a screening tool for NNJ, we assessed the knowledge, attitude, and perceptions of Ghanaian mothers on NNJ at baseline. Methods: Using a cross-sectional design, mothers attending antenatal and postnatal clinics at 3 selected health facilities in 2 geographical regions of Ghana were interviewed. Data on mothers’ understanding, perceptions, beliefs, and actions towards NNJ were evaluated. Chi-square test was used to determine the association between selected maternal characteristics and knowledge, attitude, and perception to NNJ. Results: Of the 504 mothers interviewed, 428(85.4%) had heard about NNJ, 346 (68.7%) said the earliest signs are seen in the eyes, 384(76.2%) knew NNJ may be harmful and 467(92.7%) recommended seeking healthcare for the jaundiced newborn. None of the women knew about G6PD or their G6PD status following antenatal screening. Most did not know the signs/symptoms of severe NNJ. Of the 15 mothers who had had a jaundiced neonate, cost was the most perceived (8 out of 15) barrier to accessing health care. There were significant associations (p-value ≤ 0.05) between maternal age, educational level, and knowledge of NNJ. Conclusion: Despite the high level of awareness of NNJ, gaps still exit in the knowledge, attitudes and perceptions of mothers concerning NNJ. Improving education of women about the causes, symptoms/signs, and the role of G6PD in severe NNJ is recommended. Addressing barriers to accessing healthcare for the jaundiced infant may enhance timely management of NNJ and reduce the associated complications and mortality

Safety and Immunogenicity of Different Immunization Regimens of CVD 103-HgR Live Oral Cholera Vaccine in Soldiers and Civilians in Thailand

Attenuated Vibrio cholerae oral vaccineCVD 103-HgR was well tolerated by 324 Thai soldiers and civilians. Most receiveda single 5 × 108 cfu dose, while 40 each receivedone or two 5 × 109 cfu doses. Vibriocidal antibody (the best correlate of immunity) seroconversion was lower in soldiers than civilians (P < .001). Increasing the vaccinedose to 5 × 109 cfu raised the geometric mean titer (P < .001).Asecond 5 × 109 cfu dose one weeklater did not notably increase seroconversions. Likelihood of seroconversionwas inverselycorrelated with baseline vibriocidal titer (P < .001). CVD 103-HgR caused seroconversion in most subjects with baseline titers ⩽1:40, including 100% of civilians after one 5 × 108 cfu dose, 79% of soldiers after one 5 × 109 cfu dose, and 45% of soldiers after one 5 × 108 cfu dose. In persons with elevatedbaseline titers, vibriocidal antibody seroconversion is not a sensitive measure of whether vaccine has boosted intestinal immunity; for such subjects,other measurements must be used. Study regimens in endemic areas should use a single 5 × 109 cfu dos

Measurement Report: Firework Impacts on Air Quality in Metro Manila, Philippines, during the 2019 New Year Revelry

Fireworks degrade air quality, reduce visibility, alter atmospheric chemistry, and cause short-term adverse health effects. However, there have not been any comprehensive physicochemical and optical measurements of fireworks and their associated impacts in a Southeast Asia megacity, where fireworks are a regular part of the culture. Size-resolved particulate matter (PM) measurements were made before, during, and after New Year 2019 at the Manila Observatory in Quezon City, Philippines, as part of the Cloud, Aerosol, and Monsoon Processes Philippines Experiment (CAMP2Ex). A high-spectral-resolution lidar (HSRL) recorded a substantial increase in backscattered signal associated with high aerosol loading ∼440 m above the surface during the peak of firework activities around 00:00 (local time). This was accompanied by PM2.5 concentrations peaking at 383.9 µg m−3. During the firework event, water-soluble ions and elements, which affect particle formation, growth, and fate, were mostly in the submicrometer diameter range. Total (\u3e0.056 µm) water-soluble bulk particle mass concentrations were enriched by 5.7 times during the fireworks relative to the background (i.e., average of before and after the firework). The water-soluble mass fraction of PM2.5 increased by 18.5 % above that of background values. This corresponded to increased volume fractions of inorganics which increased bulk particle hygroscopicity, kappa (κ), from 0.11 (background) to 0.18 (fireworks). Potassium and non-sea-salt (nss) SO42- role= presentation style= box-sizing: border-box; border-radius: 0px; display: inline; line-height: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative; \u3e2−4 contributed the most (70.9 %) to the water-soluble mass, with their mass size distributions shifting from a smaller to a larger submicrometer mode during the firework event. On the other hand, mass size distributions for NO3- role= presentation style= box-sizing: border-box; border-radius: 0px; display: inline; line-height: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative; \u3e−3, Cl−, and Mg2+ (21.1 % mass contribution) shifted from a supermicrometer mode to a submicrometer mode. Being both uninfluenced by secondary aerosol formation and constituents of firework materials, a subset of species were identified as the best firework tracer species (Cu, Ba, Sr, K+, Al, and Pb). Although these species (excluding K+) only contributed 2.1 % of the total mass concentration of water-soluble ions and elements, they exhibited the highest enrichments (6.1 to 65.2) during the fireworks. Surface microscopy analysis confirmed the presence of potassium/chloride-rich cubic particles along with capsule-shaped particles in firework samples. The results of this study highlight how firework emissions change the physicochemical and optical properties of water-soluble particles (e.g., mass size distribution, composition, hygroscopicity, and aerosol backscatter), which subsequently alters the background aerosol\u27s respirability, influence on surroundings, ability to uptake gases, and viability as cloud condensation nuclei (CCN)

TBVAC2020 : advancing tuberculosis vaccines from discovery to clinical development

TBVAC2020 is a research project supported by the Horizon 2020 program of the European Commission (EC). It aims at the discovery and development of novel tuberculosis (TB) vaccines from preclinical research projects to early clinical assessment. The project builds on previous collaborations from 1998 onwards funded through the EC framework programs FP5, FP6, and FP7. It has succeeded in attracting new partners from outstanding laboratories from all over the world, now totaling 40 institutions. Next to the development of novel vaccines, TB biomarker development is also considered an important asset to facilitate rational vaccine selection and development. In addition, TBVAC2020 offers portfolio management that provides selection criteria for entry, gating, and priority settings of novel vaccines at an early developmental stage. The TBVAC2020 consortium coordinated by TBVI facilitates collaboration and early data sharing between partners with the common aim of working toward the development of an effective TB vaccine. Close links with funders and other consortia with shared interests further contribute to this goal
