Effectiveness of Rotarix® vaccine in Africa in the first decade of progressive introduction, 2009-2019: systematic review and meta-analysis
Authors: Murunga Nickson , P. Otieno Grieven , Maia Marta , N. Agoti Charles 
Published: August 2020

Background: Randomized controlled trials of licensed oral rotavirus group A (RVA) vaccines, indicated lower efficacy in developing countries compared to developed countries. We investigated the pooled effectiveness of Rotarix® in Africa in 2019, a decade since progressive introduction began in 2009. Methods: A systematic search was conducted in PubMed to identify studies that investigated the effectiveness of routine RVA vaccination in an African country between 2009 and 2019. A meta-analysis was undertaken to estimate pooled effectiveness of the full-dose versus partial-dose of Rotarix® (RV1) vaccine and in different age groups. Pooled odds ratios were estimated using random effects model and the risk of bias assessed using Newcastle-Ottawa scale. The quality of the evidence was assessed using GRADE. Results: By December 2019, 39 (72%) countries in Africa had introduced RVA vaccination, of which 34 were using RV1. Thirteen eligible studies from eight countries were included in meta-analysis for vaccine effectiveness (VE) of RVA by vaccine dosage (full or partial) and age categories. Pooled RV1 VE against RVA associated hospitalizations was 44% (95% confidence interval (CI) 28-57%) for partial dose versus 58% (95% CI 50-65%) for full dose. VE was 61% (95% CI 50-69%), 55% (95% CI 32-71%), 56% (95% CI 43-67%), and 61% (95% CI 42-73%) for children aged <12 months, 12-23 months, <24 months and 12-59 months, respectively. Conclusion: RV1 vaccine use has resulted in a significant reduction in severe diarrhoea in African children and its VE is close to the efficacy findings observed in clinical trials. RV1 VE point estimate was higher for children who received full dose than those who received partial dose, and its protection lasted beyond the first year of life.
A Bayesian Level-k Model in n-Person Games
Authors: Ho Teck-Hua , Park So-Eun , Su Xuanming 
Published: August 2020

In standard models of iterative thinking, players choose a fixed rule level from a fixed rule hierarchy. Nonequilibrium behavior emerges when players do not perform enough thinking steps. Existing approaches, however, are inherently static. This paper introduces a Bayesian level-k model, in which level-0 players adjust their actions in response to historical game play, whereas higher-level thinkers update their beliefs on opponents’ rule levels and best respond with different rule levels over time. As a consequence, players choose a dynamic rule level (i.e., sophisticated learning) from a varying rule hierarchy (i.e., adaptive learning). We apply our model to existing experimental data on three distinct games: the p-beauty contest, Cournot oligopoly, and private-value auction. We find that both types of learning are significant in p-beauty contest games, but only adaptive learning is significant in the Cournot oligopoly, and only sophisticated learning is significant in the private-value auction. We conclude that it is useful to have a unified framework that incorporates both types of learning to explain dynamic choice behavior across different settings.

Published: August 2020

A photonic-assisted broadband and high-resolution microwave frequency measurement scheme is proposed and demonstrated based on undersampling via using three cavity-less optical pulse sources with coprime repetition rates. After undersampling by three ultrashort pulse trains with repetition rates in the order of gigahertz, input microwave signal is down-converted to three intermediate-frequency (IF) signals located in the first Nyquist frequency range. Through measuring the frequencies of the IF signals via fast Fourier transform after digitization by the commercially available analog-to-digital convertors, the input microwave signal frequency can be retrieved based on the frequency identification algorithm. In the proof-of-concept experiment, three ultrashort pulse trains with repetition rates of 2.99, 3.07, and 3.10 GHz are generated by a cavity-less optical pulse source, where the pulse widths are 9.5, 9.6, and 9.8 ps, respectively. Through using these three ultrashort optical pulse trains, a frequency measurement range up to 40 GHz is realized, where the frequency measurement error is less than

Systemics of Violent Religious Nationalism
Authors: Kiper Jordan , Sosis Richard 
Published: August 2020

What universal features of the mind interact with specific ecologies to produce expressions of violent religious nationalism? To shed light on this question, we focus on a case study of the Yugoslav Wars, asking: How did different religious groups in the Balkans move from cooperative relationships to violent ones? We argue that the most prevalent theories invoked to answer this question fail to adequately explain the change, namely, both the rise and fall of violent religious nationalism in the Balkans. To that end, we employ a systemic framework of religious change to examine historical data and ethnographic interview excerpts from ex-fighters and survivors of the Yugoslav Wars. This framework takes religion as it is practiced by communities to be a complex adaptive system, and models how religions adapt to local socioecologies. In employing this framework, three questions are addressed: (1) What features of cognition contributed to religiously motivated mass violence; (2) Which constituents of the religious system triggered those features; and (3) What socioecological factors were those constituents responding to? We argue that popular support for religious violence—and eventually its rejection—involved a set of higher-order functions, which McNamara calls the centralized executive self. This decision-making system was decentered by religious specialists who raised social pressures; group rituals that sustained community engagement; and identity-markers that signaled group commitments. While support for violence was a response to community threats during state-level succession, the eventual rejection of violence by religious leaders and communities was due to socioecological factors, such as rising health threats and declining birth rates brought about by the wars.

Published: August 2020

En este artículo se plantea un diseño experimental 2k donde se evalúan las concentraciones de microorganismos probióticos en los cereales infantiles que actualmente se comercializan en el mercado. Los ensayos se llevaron a cabo en un laboratorio de Biotecnología donde se realizó la interacción de los siguientes factores: tipo de microorganismo, temperatura y tipo de siembra, los cuales fueron probados en una simulación en el tracto digestivo y metodología basada en el tipo de siembra directa e indirecta en los medios de cultivos específicos con un recuento de unidades formadoras de colonias (UFC) para la identificación de los niveles de crecimiento del Bifidobacterium Lactis y Bacillus Coagulans. En esta práctica, se demuestra que el probiótico “Bacillus Coagulans” es de fácil detección en la siembra directa; a diferencia del “Bifidobacterium Lactis” que no tienen un crecimiento de bacterias acido láctica con ninguna de las dos siembras utilizadas, lo que significa que hubo resistencia para la generación de unidades formadoras de colonias (UFC). Cabe resaltar que los “Microorganismos Probióticos” en los cereales infantiles deben estar presente en toda la vida útil del producto y ser de fácil liberación. Es por esto, que los factores que mejor intervienen en las UFC son fijados a una temperatura de 37ºC y basados en una metodología indirecta para la obtención de recuentos de bacterias ácido láctico

Migrant Crossing Borders: Bridging Cultural Difference and Securing a Third Space in the Host Country
Authors: Murniati Tri 
Published: August 2020

Being migrant workers means being ready to face and accept the challenge of cultural differences in the host country. Bridging in two different cultures, this involves adaptation. However, the process of adaptation—welcoming, embracing and finally accepting—to the host country’s culture is not easy. Tearing between the two different worlds, their migrant experience can be torturous. These migrants are not only transitioning into a new life in the host country but also translating a new culture in their new life phase. Such experiences, then, open up a space—an interstice—which enables these migrants to survive in the new life, the migrant life. Taking, observing, and interpreting the stories of the Indonesian domestic workers (IDWs) in Hong Kong, I argue that these women are able to not only translate but also adoptthe new culture of the host country through assimilation, acculturation and the invention of a common ground, a third space in which they are able to feel like home in the host country. In addition, the process of acculturation involves negotiation which allows IDWs to find a middle ground between two different cultures and the third space illustrates their adjustment in bridging and crossing the cultural border between the home and the host countries. Between Indonesia and Hong Kong, Victoria Park arises as a comfort space which can ease the pain of being stranger in Hong Kong.

This research was aimed to know the effect of different fermented organic feed on the growth performance of Oithona sp. in semi-mass culture condition. The Oithona sp. cultures were fed with mixed organic fermentation of pulp, bran and fish meal by using probiotic microbes and phytoplankton cells. There were 4 treatments and 4 replicates. Treatment A was the Oithona sp. cultured with added Chaetoceros calcitrans cells without fermented organic feed (0 g ∙ L–1 of medium culture). While B, C, and D were added with the same numbers of that C. calcitrans cells of 2x106 cells ∙ mL–1 and 0.5 g ∙ L–1, 1.0 g ∙ L–1, 1.5 g ∙ L–1 of fermented organic feed, respectively. The results showed that the dosage of fermented organic feed had significantly different effect (P < 0.05) on the growth performance of Oithona sp. culture. The best growth performance of Oithona sp. showed by adding 0.5 g ∙ L–1 of fermented organic feed, with total density of 7.09 ± 0.11 ind ∙ mL–1, population growth rate of 0.116 ± 0.002 ind ∙ d–1 and eggs production of 7.88 ± 0.93 eggs ∙ ind–1 of adult.
