Background
The effects of multiple meteorological factors on influenza activity remain unclear in Chongqing, the largest municipality in China. We aimed to fix this gap in this study.

Methods
Weekly meteorological data and influenza surveillance data in Chongqing were collected from 2012 to 2019. Distributed lag nonlinear models (DLNMs) were conducted to estimate the effects of multiple meteorological factors on influenza activity.

Results
Inverted J-shaped nonlinear associations between mean temperature, absolute humidity, wind speed, sunshine and influenza activity were found. The relative risks (RRs) of influenza activity increased as weekly average mean temperature fell below 18.18°C, average absolute humidity fell below 12.66 g/m3, average wind speed fell below 1.55 m/s and average sunshine fell below 2.36 hours. Taking the median values as the references, lower temperature, lower absolute humidity and windless could significantly increase the risks of influenza activity and last for 4 weeks. A J-shaped nonlinear association was observed between relative humidity and influenza activity; the risk of influenza activity increased with rising relative humidity with 78.26% as the break point. Taking the median value as the reference, high relative humidity could increase the risk of influenza activity and last for 3 weeks. In addition, we found the relationship between aggregate rainfall and influenza activity could be described with a U-shaped curve. Rainfall effect has significantly higher RR than rainless effect.

Conclusions
Our study shows that multiple meteorological factors have strong associations with influenza activity in Chongqing, providing evidence for developing a meteorology-based early warning system for influenza to facilitate timely response to upsurge of influenza activity.

En el estado actual de las ciencias sociales parece ocioso convocar a un debate sobre la interdisciplina. Es difícil encontrar oposición en un ambiente de investigación plural en el que hace mucho se abandonaron los modelos decimonónicos de organización disciplinar. Practicarla, en cambio, supone experiencias disímbolas, desencuentros, obstáculos personales, académicos e institucionales, posiciones contrarias. ¿Cómo se vive, padece y construye la idea de la interdisciplinariedad? En agosto de 2017 el Departamento de Historia de la Universidad de Guanajuato convocó a una mesa redonda con investigadores de cuatro instituciones. En particular, se trató de complementar los trabajos de las XV Jornadas de Historia, cuyo eje temático fue “Reflexiones y debates en torno a la historia y la interdisciplina”. En general, se buscó articular un espacio renovado de la discusión permanente que se realiza en la Maestría en Historia (Estudios Históricos Interdisciplinarios) y propiciar el presente texto para Oficio (publicación que lleva la interdisciplina en su apellido y propósito: Revista de Historia e Interdisciplina) como un instrumento para hacer extensivo el intercambio de ideas.
MEG Intersubject Phase Locking of Stimulus-Driven Activity during Naturalistic Speech Listening Correlates with Musical Training

Published: February 2021

Musical training is associated with increased structural and functional connectivity between auditory sensory areas and higher-order brain networks involved in speech and motor processing. Whether such changed connectivity patterns facilitate the cortical propagation of speech information in musicians remains poorly understood. We here used magnetoencephalography (MEG) source imaging and a novel seed-based intersubject phase-locking approach to investigate the effects of musical training on the interregional synchronization of stimulus-driven neural responses during listening to naturalistic continuous speech presented in silence. MEG data were obtained from 20 young human subjects (both sexes) with different degrees of musical training. Our data show robust bilateral patterns of stimulus-driven interregional phase synchronization between auditory cortex and frontotemporal brain regions previously associated with speech processing. Stimulus-driven phase locking was maximal in the delta band, but was also observed in the theta and alpha bands. The individual duration of musical training was positively associated with the magnitude of stimulus-driven alpha-band phase locking between auditory cortex and parts of the dorsal and ventral auditory processing streams. These findings provide evidence for a positive relationship between musical training and the propagation of speech-related information between auditory sensory areas and higher-order processing networks, even when speech is presented in silence. We suggest that the increased synchronization of higher-order cortical regions to auditory cortex may contribute to the previously described musician advantage in processing speech in background noise.SIGNIFICANCE STATEMENTMusical training has been associated with widespread structural and functional brain plasticity. It has been suggested that these changes benefit the production and perception of music but can also translate to other domains of auditory processing, such as speech. We developed a new magnetoencephalography intersubject analysis approach to study the cortical synchronization of stimulus-driven neural responses during the perception of continuous natural speech and its relationship to individual musical training. Our results provide evidence that musical training is associated with higher synchronization of stimulus-driven activity between brain regions involved in early auditory sensory and higher-order processing. We suggest that the increased synchronized propagation of speech information may contribute to the previously described musician advantage in processing speech in background noise.

Published: February 2021

AbstractFeline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV) are retroviruses affecting felid species worldwide. A study was performed over a period of 5 months in Ireland with the aim to get an updated and more realistic prevalence of these retroviruses. A total of 183 EDTA-anticoagulated whole-blood samples were collected from cats distributed between 10 clinics. The samples were tested using both point-of-care enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR). Basic clinical data and vaccination history were also recorded for the sampled cats. The results of ELISA tests showed a prevalence of 10.4 and 3.3% for FIV and FeLV, respectively, and an apparent prevalence of 9.3% for FIV and 11.6% for FeLV with PCR. Phylogenetic analysis of the partial polymerase (pol) gene sequences obtained from 8 FIV-positive strains showed that all but one of the Irish strains belonged to FIV subtype A, and one to subtype B. The overall mean genetic similarity between the analysed strains was 91.15%.

Abstract

Bao-Yuan Decoction (BYD), a widely used traditional Chinese medicine formula, is worth developing into modern dosage forms. To assess the quality of traditional decoction, the commonly used ultra-performance liquid chromatography coupled with diode array and evaporative light scattering detection (UPLC-DAD/ELSD) method was initially applied to develop the analytical methods for the qualitative fingerprints and simultaneous quantitation of multiple marker compounds in BYD. Based on 16 batches of BYD prepared from multiple batches of qualified crude herbs combined randomly, the characteristic fingerprints were generated, with 41 and 19 common peaks detected by DAD and ELSD, respectively. Furthermore, ginsenosides Re, Rg1 and Rb1, calycosin-7-glucoside, calycosin, liquiritin, isoliquiritin apioside, isoliquiritin, glycyrrhizic acid and cinnamic acid were qualified as marker compounds to represent the herbs composing the formula. The characteristic fingerprints and the content ranges of multiple batches of the decoction were obtained, thus providing guidance for the quality control of modern dosage forms. The combination of these qualitative and quantitative methods will be an effective operational measure by which to evaluate and control the quality of BYD from traditional decoction to modern dosage forms.

Abstract
This is the first study on composition of fatty acids in hunting web of Steatoda grossa (Theridiidae) spiders and one of only four similar studies ever made. Its main contribution is a discovery that fatty acids not only cover an outside of the web fibers, but they are even more abundantly represented in the fibers’ inner structure. Although little attention has been so far attributed to the contents of fatty acids in spider silks, one has to remember that their biocompatibility combined with an extraordinary tensile strength make them a worth investigating template for material bioengineering studies.
Denúncia e alteridade: os quadrinhos de viagem de Guy Delisle
Authors: Passos Mateus Yuri 
Published: February 2021

O foco de nossa atenção neste artigo é a obra de Guy Delisle, que se especializou em trabalhos de caráter autobiográfico e em certa medida denuncista, embora os mais recentes tenham ganhado uma dimensão mais favorável à humanização e alteridade. Como toda narrativa de viagem, as quatro narrativas que discutiremos brevemente aqui – Shenzhen, Pyongyang, Crônicas Birmanesas e Crônicas de Jerusalém – são, assim, narrativas da descoberta do outro, narrativas da experiência e do cotidiano. Enquanto conjunto, porém, elas constituem uma espécie de narrativa de formação em que acompanhamos o gradual amadurecimento do sujeito narrador, de suas visões de mundo e de sua relação com o Outro que se apresenta em suas vivências em terras estrangeiras.
MORE THAN FRIENDS: THE IMPACT OF SOCIAL MEDIA ON WORD OF MOUTH, BRAND LOYALTY AND PURCHASE INTENTIONS FOR INTERNATIONAL HOTELS
Authors: Chang Wen-Jung , M. Katrichis Jerome 
Published: January 2021

Purpose of the study: Increases in global travel have led to the internationalization of the hospitality industry. Though a number of applications of social media have been examined in the hospitality industry, few of them integrate key dimensions of fan pages into a measurement model in the same time, including interactivity (INT), engagement (ENG), trust (TRT), friendship (FRP), word-of-mouth (WOM) and purchase intention (PI).
Methodology: Based on 408 valid fans from Facebook fan pages of 24 International hotels in Taiwan, the empirical results show that ENG, FRP, TRT, and WOM all act as partial mediators in their impact on post-purchase behaviors. Based on Taiwanese International hotels, this study attempts to explore why these owners want more than just a friend.
Main findings: The empirical results show that ENG, FRP, TRT, and WOM all act as partial mediators in their impact on post-purchase behaviors. The study demonstrates the mechanisms behind utilizing social media to build solid long term potentially profitable relationships with hotel clientele.
Originality/value: We propose and empirically investigate an integrated theoretical framework to more fully capture and describe the consumer’s behavior in the brand community. Our model of the social media process is informed by an “S-O-R” view from consumer behavior, where INT and ENG help create the situation which acts as a stimulus for FRP and TRT which in turn influence BL, WOM, and further PIs. Here, we see the pull force (website INT) as an influence on the brand-consumer relationship (i.e., FRP) through a push force (fan’s ENG). Together and along with the brand content they combine to create the consumer stimulus.

<p>Problem solving, creative thinking, and reasoning skills are important skills for students to master to solve various problems that they will face in the future. However, there are still many students that have relatively low ability levels performing these three skills. To improve students' abilities in these three skills, teachers can use learning strategies that incorporate visual learning media. The problem identified in a class of third graders at a public elementary school (SDN 01) in Jagakarsa was the lack of use of learning media in the learning process in the classroom so students' ability in all three skills was less developed. A research study was conducted to determine the increase in problem solving skills, creative thinking skills, and reasoning skills of third grade students at SDN 01 Jagakarsa in math subjects after being taught using instructional media. Data sources were obtained from students' test scores before and after being taught using visual learning media. Based on the N-gain calculation and data analysis using inferential statistics, results showed that the use of visual learning media can improve students' ability to solve problems, think creatively, and reason, especially in mathematics subjects.</p><p><strong>BAHASA INDONESIA ABSTRACT: </strong>Keterampilan memecahkan masalah, berpikir kreatif, dan menalar merupakan keterampilan yang penting dikuasai siswa untuk menyelesaikan bermacam persoalan yang akan dijumpainya kelak di masa yang akan datang.

This study tested the sublethal toxicity of mercury (Hg) in the flesh and tissue of tilapia (Oreochromis niloticus). This research used an experimental method completely randomized design (CRD) with 3 treatments and 3 replications. The treatments used different Hg concentrations: Treatment A = 0.08 ppm; B = 0.16 ppm; C = 0.24 ppm; and the control group = without the addition of Hg. The parameters observed were the accumulation of mercury (Hg) in the flesh and tissue damage (histopathology) of the gills, kidneys and liver of tilapia. The results showed that the highest Hg accumulation was at the highest Hg concentration (treatment C = 0.24 ppm). Tissue damage was mainly found in the kidneys, liver and gills of fish exposed to Hg with indications of bleeding, tubular necrosis, vacuolization of epithelial cells, and mononuclear cell infiltration. The results showed that the toxicity of mercury to the organs increased with the increase in the concentration of Hg in water. Keywords : flesh, mercury, Oreochromis niloticus, sublethal, tissue
