2019/2020 Learning Centre Practice in Aotearoa/New Zealand: Report
Authors:   Massey University, New Zealand, Tanner Julia , Gao Xiaodan ,   Victoria University of Wellington, New Zealand
Published: November 2021

Data on the services and staffing in tertiary learning centres are necessary for providing professional support for tertiary learning advisors (TLAs). Full scale surveys of Aotearoa New Zealand centres were conducted in 2008 and 2013. In 2019, a third survey was conducted to explore whether the identified trends were continuing and whether there were any changes. This survey was sent to managers and team leaders at 26 tertiary learning institutions in Aotearoa New Zealand. Four topics were investigated: 1) the professional status of TLAs; 2) learning centre organisation; 3) the services provided by TLAs; 4) trends and changes since 2013. In 2020, when the lockdown resulting from the Covid-19 pandemic meant all centres had to cease operating face-to-face services for an extended period, some follow-up questions about the impact of Covid-19 were sent to the respondents of the 2019 survey. This report presents the five main findings of the 2019/2020 surveys, and provides comparisons with the previous surveys. First, more TLAs had postgraduate qualifications, and more TLAs were given general/professional contracts than academic contracts. Second, fewer learning centres were part of libraries or teaching and learning development units. Third, centres provided a similar range of services, with an increase in pastoral and wellbeing support. Fourth, services were more embedded, and more were delivered in online/blended modes, particularly since Covid-19. Lastly, changes in learning centres’ structures and service delivery were due to institutional financial pressure and student needs. We make some recommendations, including changing some questions in future surveys, updating the ATLAANZ professional practice document regularly, and implementing a TLA accreditation scheme in Aotearoa New Zealand.

The clinical outcome of SARS-CoV-2 infections, which can range from asymptomatic to lethal, is crucially shaped by the concentration of antiviral antibodies and by their affinity to their targets. However, the affinity of polyclonal antibody responses in plasma is difficult to measure. Here we used microfluidic antibody affinity profiling (MAAP) to determine the aggregate affinities and concentrations of anti–SARS-CoV-2 antibodies in plasma samples of 42 seropositive individuals, 19 of which were healthy donors, 20 displayed mild symptoms, and 3 were critically ill. We found that dissociation constants, Kd, of anti–receptor-binding domain antibodies spanned 2.5 orders of magnitude from sub-nanomolar to 43 nM. Using MAAP we found that antibodies of seropositive individuals induced the dissociation of pre-formed spike-ACE2 receptor complexes, which indicates that MAAP can be adapted as a complementary receptor competition assay. By comparison with cytopathic effect–based neutralisation assays, we show that MAAP can reliably predict the cellular neutralisation ability of sera, which may be an important consideration when selecting the most effective samples for therapeutic plasmapheresis and tracking the success of vaccinations.
“A Disneylândia das gordas”
Authors: Salles Bruna
Published: November 2021

Este artigo tem como objetivo analisar a evolução da moda plus size na capital paulista nos últimos anos. São discutidas as dificuldades que pessoas gordas enfrentam ao comprarem roupas na cidade de São Paulo. Discorre-se sobre a moda plus no município a partir do surgimento de três polos, quais sejam: a rua Domingos de Moraes, a rua José Paulino e suas mediações e a região do Brás. A partir das pesquisas feitas nessas localidades, foi possível perceber que o tratamento dispensado pelos funcionários com o público que veste acima do 48 não é o adequado. Nesse sentido, foi iniciada a terceira parte da pesquisa, descrevendo a feira de moda Pop Plus e a importância daesse espaço para pessoas gordas, tanto para aquelas que vão para consumir os produtos, quanto para as que procuram esse local para estabelecer socialização, afeto e trocas. Ademais, é mencionado também o surgimento de outras feiras de moda plus size em outras cidades – sejam ou não do Estado de São Paulo –, feiras estas que foram concebidas a partir do advento do Pop Plus.
Atrizes gordas também usam figurinos
Authors: Metz Márcia
Published: November 2021

O texto traz reflexões acerca da relação das atrizes gordas com os figurinos de suas personagens e com figurinistas. Contextualiza a importância do figurino na realização de um espetáculo, sendo muito mais do que uma roupa. Aborda um pouco da realidade das atrizes gordas. A partir de alguns depoimentos de atrizes e vivências pessoais da autora certas tensões são evidenciadas nessa relação atrizes gordas/figurinos/figurinistas. Quando falamos de figurinos pensados para atrizes que não são magras, um reflexo da opressão estética e da gordofobia que vigoram socialmente aparecem no meio teatral. O artigo com essas ponderações propõe que repensemos essa estrutura para que as atrizes gordas possam usar quaisquer tipos de figurinos, sem que isso se torne uma problemática.

Published: November 2021

O processo de conservação de sêmen sob resfriamento necessita de adição de diluentes, contendo diferentes formulações. Estudos com adição de gema de ovo ao diluente apresentam resultados divergentes quanto a qualidade espermática, durante a conservação e criopreservação em diferentes espécies de mamíferos. Diante disso, o objetivo deste experimento foi avaliar a qualidade espermática de sêmen canino adicionado de diluente a base de leite e gema de ovo de galinha a 2%, mantido sob resfriamento a 5ºC por 72h. Para isso, 20 ejaculados foram coletados de caninos e submetidos a dois tratamentos: 1) Diluente Sem Gema e 2) Diluente Com Gema de ovo de galinha a 2%. As amostras foram mantidas em geladeira a 5ºC e avaliadas as 24, 48 e 72h de resfriamento quanto a motilidade, vigor, integridade de membrana plasmática e morfologia. A análise estatística incluiu estatística descritiva, Shapiro–Wilk, Wilcoxon, análise de variância (ANOVA), comparação de médias pelo teste de Tukey. Os valores foram expressos em a média ± erro padrão da média. Foi verificada diferença significativa entre os tratamentos quanto à motilidade às 48h (Sem Gema 38,3±4,2% e Com Gema 51,5±4,7%) e 72h (Sem Gema 30±4,8% e Com Gema 38,4±5,1%) (p<0,05). O vigor, a integridade funcional da membrana plasmática e a morfologia espermática não foram significativamente afetados pelo tratamento. Em conclusão, os ejaculados de caninos adicionados de diluente acrescido de gema de ovo de galinha a 2% apresentaram maior percentual de motilidade durante resfriamento a 5ºC por 72h.

Published: November 2021

Durante os anos de 2002 a 2004 foi realizado estudo na região centro leste do estado de São Paulo, com objetivo de analisar quantitativamente determinantes de receptividade à presença de abrigos de morcegos hematófagos Desmodus rotundus (E. Geoffroy, 1810, Chiroptera, Phyllostomidae) utilizando de Sistema de Informações Geográficas (SIG). Foram encontrados 1.566 D. rotundus distribuídos em 93 abrigos em 18 municípios. Em relação à topografia, a maioria dos abrigos artificiais estavam localizados em áreas de baixas declividades e em cotas altimétricas inferiores a 712 m, porém a maioria dos abrigos naturais estavam localizados em cotas altimétricas entre 712 - 812 m podendo ser um indício de altitudes preferenciais à colonização de D. rotundus para esse tipo de abrigo. Em relação à cobertura e ao uso do solo, a maioria dos abrigos estavam em área de agricultura e nenhum abrigo natural foi encontrado em áreas de formação florestal, indicando alto grau de antropização do meio rural e florestal da região, com aumento da oferta de abrigos artificiais para D. rotundus em relação aos abrigos naturais. A quantificação dos fatores de receptividade relacionados à topografia e ao tipo e cobertura do solo podem auxiliar na elaboração de modelos de áreas de risco de ataques de morcegos hematófagos a herbívoros domésticos, devendo-se levar em consideração os efeitos de escala de cada trabalho e as características de paisagem da região estudada.
Fostering intercultural learning through project-based learning in Vietnamese tertiary EFL classes: A participatory action research study
Authors:   , Ta Minh
Published: November 2021

Intercultural competence (IC) is increasingly recognized globally as a goal of education. In Vietnam, despite emphasis on intercultural competence in national language education, research has shown the peripheral role of addressing culture in EFL classes although research on the topic of how to cultivate intercultural language teaching and learning (ICLTL) is growing. This study investigated affordances for intercultural learning through project-based learning (PBL) in an EFL program at a Vietnamese university. It followed an interpretive research paradigm and qualitative research approach. It included two related studies. Study 1 was an ethnography-informed study, which involved 14 teachers, 265 students, 6 graduates and their employers. Data were collected from classroom observations, student focus group interviews, and interviews with teachers, graduates and employers. This preliminary research revealed few opportunities for intercultural learning in this program. Specifically, it found that culture was rarely addressed, and the main instructional method for culture was fact transmission. Moreover, teachers showed limited understanding of ICLTL and students expressed the need for further culture learning. Study 2 was a participatory action research study, in which a semester-long project was introduced to foster intercultural learning. Study 2 included two workshops, one at the beginning and one in the middle of the project. In these workshops, the researcher and three teachers collaboratively learned about ICLTL, and planned PBL lessons. Drawing on a thematic analysis of classroom data and teachers’ and students’ reports, the findings showed teachers’ improved practices and understanding of ICLTL and PBL, and indications of students’ IC development throughout the project. This research contributes to the growing scholarship on ICLTL by providing evidence for the efficacy of PBL for intercultural learning. Additionally, the study highlights the impact of teacher professional development on teaching practice and extends understanding of how to incorporate PBL in a textbook-based and exam-oriented EFL context.

An Empirical Analysis of Director Mingjun Zhao’s Experience in Treating Chronic Heart Failure
Authors: He Zijuan , Zhao Mingjun
Published: November 2021

With the aggravation of an aging population, the prevalence of chronic heart failure is increasing. As a famous traditional Chinese medicine practitioner in Shaanxi Province, Mingjun Zhao is amicable at using traditional Chinese medicine to treat chronic heart failure. He believes that the pathogenesis of the condition is mainly due to the lack of heart Yang, deficiency of heart Qi, as well as the combination of water and blood stasis. Therefore, in treating this condition, it is essential to warm and nourish heart Yang, replenish Qi to benefit water, and promote blood circulation to remove blood stasis. Based on the standardized treatment used in western medicine, traditional Chinese medicine should be reasonably and accurately combined with it as a drug pair into a prescription, thus highlighting the advantages of the combination of traditional Chinese medicine in the treatment of chronic heart failure to a great extent.

RHMX: Bus arrival time prediction via mixed model
Authors: Jia Fei , Zhang Huibing , Hu Xiaoli
Published: November 2021

With the widespread use of information technologies such as IoT and big data in the transportation business, traditional passenger transportation has begun to transition and upgrade into intelligent transportation, providing passengers with a better riding experience. Giving precise bus arrival times is a critical link in achieving urban intelligent transportation. As a result, a mixed model-based bus arrival time prediction model (RHMX) was suggested in this work, which could dynamically forecast bus arrival time based on the input data. First, two sub-models were created: bus station stopping time prediction and interstation running time prediction. The former predicted the stopping time of a running bus at each downstream station in an iterative manner, while the latter projected its running time on each downstream road segment (stations as the break points). Using the two models, a group of time series data on interstation running time and bus station stopping time may be predicted. Following that, the time series data from the two sub-models was fused using long short-term memory (LSTM) to generate an approximate bus arrival time. Finally, using Kalman filtering, the LSTM prediction results were dynamically updated in order to eliminate the influence of aberrant data on the anticipated value and obtain a more precise bus arrival time. The experimental findings showed that the suggested model's accuracy and stability were both improved by 35% and 17%, respectively, over AutoNavi and Baidu.

Correlations between P2RX1 Expression and Gastrointestinal Cancers Prognosis and Immune Infiltration Based on Bioinformatics Analysis
Authors: Li Ting , Feng Jiankai , Yan Pihong , Tan Hongwei , Wang Lili , Li Qiang , Yu Yunliang
Published: November 2021

This study was conducted to explore the correlations between the expression, methylation, and various clinicopathological factors of purinergic P2X1 receptor (P2RX1) and the prognosis of patients with gastrointestinal tumors. The Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression (GTEx) databases were used to analyze the expression of P2RX1 in different types of gastrointestinal cancers. Kaplan-Meier analysis and univariate Cox regression analysis were used to analyze the correlations between P2RX1 expression and the prognosis of various gastrointestinal tumors. Correlations between P2RX1 expression and N6 methyladenine (m6A)-related genes as well as immune checkpoint genes were analyzed by R packages (R version: 4.0.3) based on TCGA database. The association between P2RX1 methylation level and the prognosis of patients with gastrointestinal cancers was analyzed using the MethSurv database. In order to explore the biological functions of P2RX1 in hepatocellular carcinoma, the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) enrichment analysis were carried out using R software. In order to evaluate the correlations between P2RX1 and tumor immune infiltration, Spearman correlation test was performed. The correlations between P2RX1 expression and immune score as well as immune checkpoint genes were analyzed based on TCGA and Tumor Immune Estimation Resource (TIMER) databases. The expression of P2RX1 was found to be significantly downregulated in gastrointestinal tumors except in cholangiocarcinoma (P < 0.05). High expression of P2RX1 tended to present better prognosis in hepatocellular carcinoma (P < 0.05). It was noted that cg06475633 of P2RX1 presented a higher methylation level compared with other CpG sites in hepatocellular carcinoma. Overall, six CpGs of P2RX1 were associated with significant prognosis in patients with hepatocellular carcinoma (P < 0.05). Among all the 20 m6A-related genes, Wilms’ tumor 1-associating protein (WTAP) was the most strongly correlated with P2RX1 in hepatocellular carcinoma. Gene enrichment analysis showed that P2RX1 is widely involved in the proliferation, activation, organization, and differentiation of various immune cells. After investigating the TIMER database, P2RX1 was found to be tightly correlated with immune infiltrating cells in gastrointestinal tumors, especially with dendritic cells. Moreover, P2RX1 was found to be strongly positively associated with programmed cell death 1 (PD1), programmed death-ligand 1 (PD-L1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA4) in hepatocellular carcinoma (P < 0.05). In conclusion, the dual role of P2RX1 in cancers and its involvement in the recruitment as well as regulation of tumor infiltrating cells in gastrointestinal cancers may be appreciated through this study.
