The attainment of herd immunity with a restructured risk of contact infection in compartmental models
Authors: Law Kian Boon , Peariasamy Kalaiarasu M , Ibrahim Hishamshah , Abdullah Noor Hisham 
Published: March 2021

Abstract
Introduction: The risk of contact infection among susceptible individuals in a randomly mixed population can be reduced by the presence of immune individuals and this concept is referred as herd immunity. Although herd immunity is observed in vaccinated population for some infectious diseases, it has never been truly attained in compartmental models such as the susceptible-infectious-recovered (SIR) model. This paper introduces a new SIR framework to overcome the limitation of the conventional SIR model in attaining herd immunity.Methods: Two SIR models were newly developed based on the reduced risk of contact infection. The first model A assumes that the risk of contact infection reduces as soon as susceptible individuals are infected and move from class S(t) to I(t), therefore incorporating prevalence of both infectious and susceptible individuals into its force of infection. The second model B assumes the risk of contact infection would reduce after infected individuals have recovered from infection and move from class I(t) to R(t), therefore incorporating the prevalence of infectious and the inverse of prevalence of recovered individuals into its force of infection. Then, numerical simulations were applied to obtain approximate solutions for all three conventional SIR model, new SIR model A and model B for comparison under exact and arbitrary conditions with β = 0.3 and σ = 0.1 to mimic the infection dynamics with basic reproduction ratio (r0) of 3.0 and herd immunity threshold (HIT) of 0.667 (66.7%).Results and discussion: All three models performed likewise at the initial stage of epidemic. The conventional SIR model simulated the epidemic diminishing when 94.0% of the population had been infected and recovered, way above its HIT. Model A simulated the epidemic waning when 66.7% of the population had been infected and recovered, in line with its HIT, however, the model conceptualized the herd immunity incorrectly. Model B simulated the epidemic waning at 75.6%, slightly above its HIT and was in line with the fundamental of herd immunity. The difference between model A and model B can be attributed to the proportion of infectious individuals, and this would increase in infectious disease with high transmissibility. The threshold theorem derived based on r0 may not be sufficient for optimal control and eradication of infectious disease with high transmissibility like the COVID-19.Conclusion: The newly developed SIR model that includes the inverse of proportion of recovered individuals into its force of infection is more accurate and credible for modelling infection with high transmissibility or vaccine-induced herd immunity in a randomly mixed population, especially in COVID-19.

Abstract
Phosphorus removal is a crucial aspect of controlling water pollution and eutrophication. In this study, the preparation of lanthanum carbonate (LC) nano-adsorbents for the efficient removal of phosphate (P) from water and wastewater was investigated. Results from XRD, SEM and Zeta potential analyses revealed that addition of magnesium ions and adjustment of the reaction temperature could control the morphology and microstructure of LC. Effects of initial pH, adsorbent dosage, contact time, and the water matrix on P adsorption were investigated. Batch adsorption experiments revealed that LC showed strong performance on P removal over a wide pH range (3.0 to 11.0). The kinetic data followed a pseudo-second-order model, and equilibrium data were well fitted by the Langmuir model with a maximum adsorption capacity of 112.9 mg P/g. Adsorption thermodynamics showed that the adsorption process was exothermic and spontaneous. Results of a monolayer model for single adsorption indicated that P could completely interact with two or more functional groups from the LC surface. In the presence of competing ions (F−, Cl−, SO42−, NO3−, and HCO3−), LC maintained high selectivity for phosphate. For a real effluent, the P concentration was efficiently reduced from 3.2 mg P/L to below 0.5 mg P/L at a dose of 0.5 g/L LC. All the results suggested that LC can serve as a promising adsorbent for P removal in a wide range of pH, and thus could meet the stricter discharge regulations from actual wastewater.

AS METAMORFOSES DE JOYCE: O LABIRINTO NA OBRA UM RETRATO DO ARTISTA QUANDO JOVEM
Authors: Raele Braga Luiz Henrique , Giordano Paz Ravel 
Published: March 2021

A obra Um retrato do artista quando jovem, escrita por James Joyce e publicada em 1916, é um dos marcos da prosa em língua inglesa do século XX, principalmente no campo do Bildungsroman. Acompanhando o desenvolvimento intelectual de seu protagonista, Stephen Dedalus – alter-ego de Joyce -, a narrativa se inicia com o personagem ainda criança, e termina quando Stephen alcança o início de sua maturidade, ou seja, quando descobre sua vocação de artista, ou, mais especificamente, de poeta. O presente trabalho, portanto, buscou analisar um dos símbolos identificados no romance, o do labirinto do inventor Dédalo, e como a referida figura mítica acaba por influenciar a própria estrutura da narrativa. Inicia-se com uma breve história da obra, para depois identificar a influência do poeta latino Ovídio – que cantou o mito ora em discussão na sua epopeia Metamorfoses – sobre escritores modernistas de expressão inglesa, limitando-se a abordar, além de Joyce, os poetas T.S. Eliot e Ezra Pound, como forma de contextualizar o uso do poema clássico no início do século XX. Por fim, analisa-se em que medida o símbolo do labirinto pode ser vislumbrado no romance, fazendo-se o uso, para tanto, de aparato crítico, como os estudos de Ellmann (1989), March (2015), Paris (1992), Parrinder (1984), Levin (1959), entre outros.
The Role of the Quality of Perceived Social Support in the Emotion Regulation Strategies of Adolescents in Jakarta [Peran Kualitas Perceived Social Support Terhadap Strategi Regulasi Emosi Remaja di Jakarta]

Adolescents are prone to emotional turmoil. Feedback received from the environment, as a form of support, is required in the process of emotion regulation. Thus, it can be assumed that perceived social support will be associated with emotion regulation. However, research linking both variables has so far included only the relationship between quality social support and a single one of the emotion regulation strategies in late adolescence. This study fills the gap, and aims to examine the relationship between quantity and quality of perceived social support with emotion regulation strategies across the entire adolescent age range in Jakarta. The measuring tool used was the Social Support Questionnaire 6 (quantity of perceived social support and perceived social support satisfaction) and the Emotional Regulation Questionnaire (cognitive reappraisal and expressive suppression strategies). The sample comprised adolescents in Jakarta who had achieved formal educational levels, and who came from families with middle to lower level Status Ekonomi Social (SES; Socio-Economic Status; N = 427). The authors used Pearson Product Correlation and linear regression data analysis techniques. The results showed that thequantity of perceived social support was not significantly associated witheither dimension of emotion regulation. Perceived social support satisfaction was significantly associated with both dimensions of emotional regulation.

Abstrak Suku Sunda menjadi salah satu suku mayoritas di Indonesia. Tetapi, karena tidak mempunyai ciri fisik yang khas seperti suku - suku yang lain, maka sulit untuk menentukan identitas suku Sunda dari segi fisiknya. Akibatnya, penelusuran sejarah dan perjalanan migrasi suku Sunda masih belum jelas. Oleh karena itu dibutuhkan pendekatan lain berupa data genetik yang dapat menggambarkan hubungan kekerabatan dan evolusinya. Analisis filogenetik urutan DNA mitokondria telah terbukti menjadi alat yang efektif untuk identifikasi seseorang dan juga dapat menunjukkan asal populasi yang berbeda. Urutan DNA mitokondria yang digunakan berada pada daerah hipervariabel I (HVI) karena tingkat variasinya yang tinggi. Pada penelitian ini, urutan DNA mitokondria yang berasal dari Kampung Baduy, Ciptagelar, Dukuh serta Kuta diisolasi, diamplifikasi untuk analisis delesi 9pb dan dikarakterisasi dengan enzim restriksi AluI danDdeI. Selain itu juga dilakukansequencingterhadap sampel Kampung Baduy dan Kuta untuk mengetahui pola migrasinya.Hasil analisis delesi 9pb dan adanya fragmen DNA hasil restriksi menunjukkan bahwa suku Sunda membawa marker Asia. Berdasarkan analisis varian dan haplogrup migrasi suku Sunda berawal dari barat ke timur,yang ditunjukkan oleh Kampung Baduy dengan haplogrup N9a6a yang lebihtua dibandingkan dengan haplogrup pada Kampung Kuta yaitu B5a
