Social network analysis of the mental health sub-topic on the MedlinePlus subject directory
Authors:   University of Wisconsin Milwaukee, Zhu Yifan , Zhang Jin ,   University of Wisconsin Milwaukee
Published: December 2020

Introduction. A subject directory plays an important role in a Web portal and it helps users effectively navigate the portal. This study examines a subject directory system related to Mental Health in the MedlinePlus portal and provides suggestions of optimisation to enhance the subject directory system. Method. A mixed research method combining social network analysis and inferential statistics was applied. Analysis. A structural and a semantic social network were built regarding the selected health topics related to mental health in the MedlinePlus portal. The two networks were compared and the outcomes were evaluated by domain experts. Results. Among the ninety-nine collected health topics related to mental health, three themes were identified through the visualisation analysis regarding grouped health topics. Patterns and characteristics of each theme group were discussed. As a result, fifty-five bidirectional and twenty-three unidirectional edges were identified and recommended to be added to the corresponding health topic pages. The recommended results indicate that the subject directory of specific mental health related topics is well constructed, while health consumer groups related topics might need more improvements. The optimised subject directory has significantly stronger semantic connection, and the results of the recommendations are consistent with the evaluation outcome of two domain experts. Conclusions. The findings of this study can provide ideas of optimising and enhancing the subject directory system to the public health portal creators and health professionals, and benefit health consumers for seeking health information online. The methodologies applied in this study may provide a novel way to investigate and enhance subject directories in general.

Authors:   Shanghai Normal University, He Huihua , He Si ,   Shanghai Normal University, Li Yan ,   Shanghai Normal University
Published: December 2020

Introduction. The current study investigated characteristics of parenting needs and questions of Mainland Chinese parents of young children. Specifically, Web text-mining technology was used to identify themes of parenting needs and questions, and parents' emotional status hidden in their question texts. Method. Total of 921,483 questions that parents posted from the top five parenting Websites in China during a 36-month study period were collected. Results. Daily care is one of the most important topics that concerned parents. Contemporary Mainland Chinese parents tend to raise questions about parental knowledge and skills. Different themes of questions could also be identified from different care-givers and different age groups of young children. Conclusions. From a parenting-oriented perspective, contemporary Chinese parents asked pesonalised questions through the Internet frequently. The considerable needs of grandparenting emerged. Programme designers and social policy makers should empower and support young children's parents with their parental knowledge, skills and emotional competence.
Talking to imagined citizens? Information sharing practices and proxies for e-participation in hyperlocal democratic settings
Authors:   Edinburgh Napier University, Cruickshank Peter , Hall Hazel ,   Edinburgh Napier University,
Published: December 2020

Introduction. Previous research in information science often uses constructs from social exchange theory to explain online information sharing. Exchange theories have a strong focus on reciprocity, yet in some communities, such as elected democratic representatives at hyperlocal level, it is observed that information is shared online for little visible return. This raises questions as to the extent to which existing models of online information sharing based on the tenets of exchange are applicable across a full range of contexts. In the case of hyperlocal representatives, this also prompts consideration of their motivations for online information sharing, and their response to apparent non-participation or lurking in this process on the part of citizens. In this paper an information sharing, practice-based approach is deployed to explore the means by which hyperlocal representatives in Scotland handle their information sharing role and address their relationship with their online lurker audiences. Method. Hour long interviews were conducted in November and December 2016 with nineteen representatives who serve on Scottish community councils. Analysis. Qualitative analysis of the interview data generated the results of the study. Results. Information sharing is regarded as an important duty of community councillors. It is largely practised as transmission or broadcast (rather than exchange) using a variety of channels, both online and face-to-face. Such efforts are, however, limited. This is due to restricted resources, a lack of familiarity with the information users (and non-users) that community councillors serve, and poor knowledge of tools for analysing online audiences. Attitudes towards online communities that largely comprise lurker audiences vary from frustration to resignation. Conclusions. While some of the findings articulate with extant knowledge and extend it further, others contradict the results of prior research, for example on online platforms as deliberative spaces. The practice-based approach as deployed in the study surfaces new contributions on proxies in information sharing. Amongst these, it adds to prior work on information seeking by proxy, and introduces the concept of information sharing by proxy.

Introduction. A multi-institutional, grant-funded project employed mixed methods to study 175 fourth-grade through graduate school students’ point-of-selection behaviour. The method features the use of simulated search engine results pages to facilitate data collection. Method. Student participants used simulated Google results pages to select resources for a hypothetical school project. Quantitative data on participants’ selection behaviour and qualitative data from their think-aloud protocols were collected. A questionnaire and interviews were used to collect data on participants’ backgrounds and online research experiences. Analysis. This paper reflects on the data collection methods and highlights opportunities for data analysis. The ability to analyse data both qualitatively and quantitatively increases the rigor and depth of findings. Results. The simulation created a realistic yet controlled environment that ensures the comparability of data within and across a wide range of educational stages. Combining data on participants’ behaviour, thoughts and characteristics provides a more complete picture of factors influencing online resource selection. Conclusions. Using simulated results pages in combination with multiple data collection methods enables analyses that create deeper knowledge of participants' information behaviour. Such a complicated research design requires extensive time, expertise and coordination to execute.

Introduction. This research aims to study a novel approach to producing tourism statistics, especially accommodation statistics, in Indonesia using scraping of online travel agent Websites. Method. Accommodation data (e.g., room availability and price) were gathered from two of the largest online travel agencies in Indonesia. All data were collected automatically from the sites’ URLs listed in the sitemap. Analysis. The data were collected daily from 6 March to 27 July 2019. Datasets from the two Websites were merged. The room occupation rate (ROR) for each province was calculated and compared with the official statistics from Statistics Indonesia. Results. The results show that the online room occupancy rates and official statistics have a similar pattern indicating the use of the Web scraping technique provides valuable information, to measure the room occupation rate with an advantage in terms of cost and collection time. Conclusions. It is feasible to use big data as a proxy of or a complement to official statistics, especially in tourism statistics. By using the Web scraping technique, the indicator that usually requires significant time and cost can be done in real-time and less cost. This new approach would improve the quality of tourism statistics produced by BPS Statistics Indonesia.
ENTRE A FRONTEIRA DA CORRUPÇÃO: MILLÔR E A NOVA REPÚBLICA
Authors: PEREIRA Pamera Francieli Corrêa
Published: December 2020

Este artigo tem como objetivo a analisar duas charges que abrangem o discurso de Millôr Fernandes sobre a Nova República (1985 - 1990) considerando a relação interdiscursiva presente no dizer do autor. As análises terão como base teórica a Teoria do Discurso de linha francesa, tendo como principal teórico Michel Pêcheux, dentre outras fontes necessárias para embasar as condições de produção do corpus, como Hugon (2009). Os objetivos que norteiam esta pesquisa se resumem em dar a conhecer a relação interdiscursiva no dizer de Millôr, no tocante a recuperação de dizeres outros; compreender que Millôr é porta-voz de um discurso que se transpõe no viés do humor sobre a política da Nova República (1985 - 1990); e buscar estabelecer pontos análogos quanto a uma política do passado e do presente. Sob o exercício de retomadas discursivas, compreender que há uma região de fronteira entre uma política honesta e a prática de uma irresponsabilidade administrativa por parte de políticos que regem em benefício próprio. O interdiscurso é o conceito mobilizado para as análises das charges eleitas neste corpus que, em consonância com as condições de produção, possibilita evocar efeitos de sentidos a partir de cada enunciado, bem como de cada imagem caricata que é analisada como fator de significação, o qual evoca um discurso. Por fim, o que justifica a temática deste trabalho é a cadência do dizer de Millôr sobre a acuidade do tema que envolve a política, e por considerar que esta rege a sociedade e impera sobre ela. PALAVRAS-CHAVE: Millôr.

Conceitos de interdisciplinaridade em pesquisas publicadas na área de ensino e educação (2009-2018)
Authors: Nascimento Naiane Gama do , Pereira Leonésia Leandro , Shaw Gisele Soares Lemos
Published: December 2020

A interdisciplinaridade é um movimento que vem se destacando no âmbito educacional, tanto na formação de professores, quanto na educação básica, ainda que haja discordância com relação ao conceito e aplicabilidade. Autores tais como Ivani Fazenda e Hilton Japiassu destacam-se enquanto precursores desse tema no Brasil, identificando a interdisciplinaridade como uma reação aos efeitos da hiperespecialização dos saberes. Objetiva-se refletir sobre conceitos de interdisciplinaridade sob a ótica de artigos publicados em periódicos científicos nacionais entre os anos de 2009 a 2018, especificamente, na área de ensino, com enfoque no ensino de ciências, avaliados em Qualis A1, A2 e B1 na Plataforma Sucupira da CAPES. Esses dados foram tratados por meio da análise de conteúdo. O estudo demonstrou uma diversidade de conceitos, todos respaldados na relação e diálogo entre as disciplinas, tendo como objetivo o rompimento da fragmentação e a análise e resolução de um determinado tema ou situação.

Published: December 2020

Considerando que a aprendizagem de um conceito ocorre durante o processo escolar, em decorrência das diversas situações matemáticas vivenciadas pelos sujeitos e, que, em se tratando do conceito de função afim, a constituição pelo aluno de suas ideias base (variável, correspondência, dependência, regularidade e generalização) deve ser proporcionada a partir dos Anos Iniciais, e desenvolvidas no decorrer da escolarização, relatamos neste texto uma investigação com o objetivo de identificar se e como essas ideias base são mobilizadas  por estudantes brasileiros dos anos finais do Ensino Fundamental e do Ensino Médio. Neste contexto, analisamos as estratégias de resolução de três tarefas sobre função afim, sendo uma tarefa do Campo Conceitual Multiplicativo, resolvida pelos seis sujeitos do Ensino Fundamental, e duas tarefas envolvendo problemas mistos, uma aplicada aos doze participantes da investigação e a outra somente aos seis alunos do Ensino Médio. Os resultados apontam principalmente dificuldades em relação à generalização.
Aspectos do ensino e aprendizagem da oralidade na escola
Authors: Barros José Batista de , Boulitreau Paula Roberta Paschoal , Rosa Adriana Letícia Torres da
Published: December 2020

Objetivamos refletir sobre os aspectos relativos ao ensino-aprendizagem da oralidade na sala de aula, dirigindo o olhar para os gêneros textuais como organizadores das práticas sociais e discursivas. Realizamos uma pesquisa qualitativa, na qual aplicamos a entrevista narrativa com dois professores de escolas públicas de Pernambuco que ensinam língua portuguesa em diferentes realidades (uma municipal e uma federal). Os professores demonstram reconhecer que a participação significativa do indivíduo nas práticas sociais, a partir do uso da linguagem oral, reflete nos processos de inclusão; apontam como importante o trabalho com a diversidade de gêneros orais, e variedades linguísticas; e, sinalizam questões históricas quanto ao trabalho do livro didático com a oralidade, indicando as necessidades de se investir na pedagogia de ensino da “fala”. Concluímos que o estudante tem a possibilidade de ampliar seus conhecimentos quando a escola se apresenta como espaço de sistematização do saber construído sócio historicamente, numa perspectiva inclusiva.
Limites e possibilidades do arcabouço analítico de Chalmers Johnson para compreender a estratégia industrial: um olhar institucionalista sobre a economia política da China
Authors: Paula Luiz Fernando de , Moura Rafael
Published: December 2020

Um dos mais notórios acontecimentos do último quarto do Século XX foi a modernização socioeconômica, tecnológica e produtiva do Leste Asiático, em especial Japão, Coreia do Sul e Taiwan. Já a partir da virada do século e continuando no presente, a República Popular da China (RPC) entraria neste grupo de nações exitosas se consolidando como potência em contínua trajetória de crescimento. Diversos enfoques teóricos buscaram explicar o sucesso desses casos, dentre eles do Estado Desenvolvimentista (ED), elaborado originalmente por Chalmers Johnson em 1982. O presente artigo objetiva fazer um balanço crítico da literatura desenvolvimentista relacionada à estratégia industrial da China, para além de examinar em que medida a economia política chinesa se adequa ou não aos quatro predicados institucionais do ED elucidados pelo autor.

Published: December 2020

O objetivo deste artigo é o de lançar luz sobre as razões pelas quais o conceito elaborado por Ignacio Rangel de “Economia do Projetamento” guarda grandes possibilidades às pesquisas no campo do desenvolvimento econômico chinês. Para tanto buscamos reelaborar o conceito o enriquecendo com novas determinações e critérios de validação que o tornam à altura do alcance do fenômeno em curso na China. Questões como as possibilidades de superação da “incerteza keynesiana”, a planificação da “destruição criativa”, a soberania monetária e o “pacto tácito de adesão" serão abordadas e tomadas como categorias internas que sustentam, enquanto face empírica, o conceito de Nova Economia do Projetamento. Concluimos afirmando que a Nova Economia do Projetamento se constitui como estágio superior de desenvolvimento do modo de produção dominante à (nova) formação econômico-social que emergiu na China como resultado das reformas econômicas iniciadas em 1978.
The Dragon and the Captain: China in the perspective of Brazil´s nationalist rightThe Dragon and the Captain: China in the perspective of Brazil´s nationalist right
Authors: Santoro Maurício
Published: December 2020

Since 2009 China has been Brazil´s biggest trade partner, and its important ally. However, the nationalist right that won the 2018 elections has a critical perspective of the country. This paper maps the views on China held by the new Brazilian government, both in terms of the economic arguments (protectionism of industry, fear of Chinese control of infrastructure and natural resources) and political concerns (the desire for a diplomatic rapprochement with the United States and anti-communism hostility towards Beijing). The paper claims that these positions are important for foreign policy decision-making and that they complicate relations with China, but that is also necessary to take into account more moderate views from other groups in the administration.

Mercado de trabalho e salário mínimo na China
Authors: Braga João Pedro , Nogueira Isabela
Published: December 2020

Este artigo analisa a evolução da política de salário mínimo na China desde o estabelecimento da “sociedade harmoniosa” do ex-presidente Hu Jintao e durante o atual “sonho chinês” de Xi Jinping, examinando-a no contexto geral de funcionamento do mercado de trabalho chinês. A elevada heterogeneidade no desenvolvimento socioeconômico do país está por trás da relativa complexidade da política de salários mínimos na China, onde não existe um dado oficial de mínimo nacional tal como no Brasil. Diante disso, esse artigo contribui empiricamente para o debate ao desenvolver um cálculo próprio do salário mínimo nacional na China de forma a analisar o comportamento do salário mínimo em relação ao salário médio, discutindo sua variação regional e seus potenciais efeitos na distribuição de renda nacional.

NATO and Collective Environmental Security in the MENA: From the Cold War to Covid-19
Authors: Al-Marashi Ibrahim , Causevic Amar
Published: December 2020

The Covid-19 pandemic emerged as a global security risk, and national security institutions scrambled to manage a threat, not emanating from states or non-state actors, but from the environment. The pandemic serves as an empirical case to explore “anthropogenic strategic security,” or how security doctrines can anticipate and mitigate natural disasters, resulting from humanity’s exploitation of ecology and environment. This qualitative study addresses the question as to whether the NATO possesses the imaginative and institutional capacity to manage environmental risks resulting from climate change. By employing constructivist theory, this article argues that the Alliance needs to adopt holistic norms and approaches towards security. By expanding its identity and mission, it should adopt policies that task its constituent parts to serve as a de-facto “Climate Alliance Treaty Organization,” particularly in the MENA region, which is extremely vulnerable to environmental risks. A review of past NATO statements, meetings, and institutions provide the key findings, demonstrating that the Alliance’s past experience in aiding non-members, such as in the Balkans and South and Central Asia, has endowed the Alliance with the infrastructure, experience, and mechanisms for strategic partnerships with MENA nations on climate mitigation strategies.

Published: December 2020

An 8 month old Modena breed of pigeon presented to teaching veterinary clinicalcomplex Mannuthy (TVCC) with the history of torticollis, anorexia, depression, inability to fly and two birds in the same flock were died due to same symptoms. On clinical examination bird appeared dull, depressed and circling of head showed. No visible ectoparasites could be detected on the detailed physical examination. Routine blood smear examination was done by taking blood from the peripheral wing vein and prepared thin blood smear. On blood smear examination characteristic halter shaped gametocytes were seen encircling the nucleus of erythrocytes. Faecal sample examination revealed the absence of intestinal parasites. Treatment was done with chloroquine @15mg per kg bodyweight in drinking water for two days along with the multivitamin supplementation. The whole flock in the house hold were treated with 2% permethrin spray by external application to control or eliminate the fly vector. After one week of the treatment reviewed the clinical condition of the bird. All signs suggesting of pigeon malaria were completely resolved, blood smear examination revealed no haemoparasites and the bird had an uneventful recovery. Pigeon malaria is considered as a fatal disease when there is a huge mortality occurred in a flock and hence the disease is getting less attention. Failure in the preventive measures to control the vector population or lack of better management practice in house keeped pigeons leads to unnoticed cause of mortality due to pigeon malaria.

Determinants of Capital Adequacy of Nigerian Banks
Authors: Abiodun Sanyaolu Wasiu , Abdul-Azeez Alao Adeniyi , Adewale Yunusa Lateef
Published: December 2020

A reliable banking system in developing economies like Nigeria is vital for economic progress as it facilitates the flow of funds to productive investment sectors. The capital adequacy requirement of banks is a crucial feature of the stability of the banks globally. Because of its importance, we have examined the antecedents to capital adequacy. We have used the data set of ten leading banks of Nigeria from 2007 to 2017. Our results indicate that ROA and loan to total assets are significantly associated with capital adequacy. However, we found that nonperforming loans and size are negatively associated with the capital adequacy. Our results do not support the association between macroeconomics variables and capital adequacy. Therefore, we recommend that all banking entities should reserve sufficient cash and cash equivalents as a percentage of deposits and apply aggressive risk management practices to reduce the magnitude of nonperforming loans. This study was restricted to one country. Future studies can be carried out in other countries. A comparative data set of more than one country may bring further insight into the phenomenonKeywords: Capital adequacy ratio, banks-specific determinants, macroeconomic determinants, Nigeria.
Wireless Networks Performance Monitoring Based on Passive-active Quality of Service Measurements
Authors: A. Al-Sbou Yazeed
Published: December 2020

Monitoring of the performance of wireless network is of vital importance for both users and the service provider which should be accurate, simple and fast enough to reflect the network performance in a timely manner. The aim of this paper is to develop an approach which can infer the performance of wireless ad hoc networks based on Quality of service (QoS) parameters assessment. The developed method considers the QoS requirements of multimedia applications transmitted over these kind of networks. This approach is based on the ideas of combination of both active and passive measurement methods. This approach uses an in-service measurement method in which the QoS parameters of the actual application (user) are estimated by means of dedicated monitoring packets (probes). Afterwards, these parameters are combined to produce and assess the application’s overall QoS using the fuzzy logic assessment and based on the measured QoS parameters estimated using the probe traffic. The active scheme is used to generate monitoring probe packets which are inserted between blocks of target application packets at regular intervals. While the passive monitoring is utilized to act as a traffic meter which performs as a counter of user packets (and bytes) that belong to the application (user) traffic flow that is subjected to monitoring. After simulating the developed technique, it offered a good estimation for the delay, throughput, packet losses and the overall QoS when using different probe rates.

Published: December 2020

Today's Internet and enterprise networks are so popular as they can easily provide multimedia and ecommerce services to millions of users over the Internet in our daily lives. Since then, security has been a challenging problem in the Internet's world. That issue is called Cyberwar, in which attackers can aim or raise Distributed Denial of Service (DDoS) to others to take down the operation of enterprises Intranet. Therefore, the need of applying an Intrusion Detection System (IDS) is very important to enterprise networks. In this paper, we propose a smarter solution to detect network anomalies in Cyberwar using Stacking techniques in which we apply three popular machine learning models: k-nearest neighbor algorithm (KNN), Adaptive Boosting (AdaBoost), and Random Decision Forests (RandomForest). Our proposed scheme uses the Logistic Regression method to automatically search for better parameters to the Stacking model. We do the performance evaluation of our proposed scheme on the latest data set NSLKDD 2019 dataset. We also compare the achieved results with individual machine learning models to show that our proposed model achieves much higher accuracy than previous works.

Abstract. Gaseous hydrochloric (HCl) and hydrobromic acid (HBr) are vital halogen species that play essential roles in tropospheric physicochemical processes. Yet, majority of the current studies on these halogen species were conducted in marine or coastal areas. Detection and source identification of HCl and HBr in inland urban areas remain scarce, thus, limiting the full understanding of halogen chemistry and potential atmospheric impacts in the environments with limited influence from the marine sources. Here, both gaseous HCl and HBr were concurrently measured in urban Beijing, China during winter and early spring of 2019. We observed significant HCl and HBr concentrations ranged from a minimum value at 1.3 × 108 cm−3 and 4.3 × 107 cm−3 up to 5.9 × 109 cm−3 and 1.2 × 109 cm−3, respectively. The HCl and HBr concentrations are enhanced along with the increase of atmospheric temperature, UVB, and levels of gaseous HNO3. Based on the air mass analysis and high correlations of HCl and HBr with the burning indicators (HCN and HCNO), the gaseous HCl and HBr are found to be related to anthropogenic burning aerosols. The gas-aerosol partitioning may also play a dominant role in the elevated daytime HCl and HBr. During the daytime, the reaction of HCl and HBr with OH radicals lead to significant production of atomic Cl and Br, up to 1.7 × 104 cm−3 s−1 and 7.9 × 104 cm−3 s−1, respectively. The production rate of atomic Br (via HBr + OH) are 2–3 times higher than that of atomic Cl (via HCl + OH), highlighting the potential importance of bromine chemistry in the urban area. Furthermore, our observations of elevated HCl and HBr may suggest an important recycling pathway of halogen species in inland megacities, and may provide a plausible explanation for the widespread of halogen chemistry, which could affect the atmospheric oxidation in China.

Published: December 2020

Abstract. Detrital zircon U–Pb geochronology is a staple of sedimentary provenance analysis and crustal evolution studies. Constructing detrital age spectra is straightforward for concordant 206Pb / 238U- and 207Pb / 206Pb-compositions. But unfortunately, many detrital U–Pb datasets contain a significant proportion of discordant analyses. This paper investigates two decisions that must be made when analysing such discordant U–Pb data. First, the analyst must choose whether to use the 206Pb / 238U- or the 207Pb / 206Pb-date. The 206Pb / 238U-method is more precise for young samples, whereas the 207Pb / 206Pb-method is better suited for old samples. However there is no agreement which cutoff should be used to switch between the two. This subjective decision can be avoided by using single grain concordia ages. These represent a kind of weighted mean between the 206Pb / 238U- and 207Pb / 206Pb-methods, which offers better precision than either of the latter two methods. A second subjective decision is how to define the discordance cutoff between good and bad data. Discordance is usually defined as (1) the relative age difference between the 206Pb / 238U and 207Pb / 206Pb dates. However, this paper shows that several other definitions are possible as well, including (2) the absolute age difference; (3) the common-Pb fraction according to the Stacey-Kramers mantle evolution model; (4) the p-value of concordance; (5) the perpendicular logratio (or Aitchison) distance to the concordia line; and (6) the logratio distance to the maximum likelihood composition on the concordia line. Applying these six discordance filters to a 10,000-grain dataset of detrital zircon U–Pb compositions reveals that: (i) the relative age discordance filter tends to suppress the young age components in U–Pb age spectra, whilst inflating the older age components; (ii) the Stacey-Kramers discordance filter is more likely to reject old grains and less likely to reject young ones; (iii) the p-value based discordance filter has the undesirable effect of biasing the results towards the least precise measurements; (iv) the logratio-based discordance filters are most strict for Proterozoic grains, and more lenient for Phanerozoic and Archaean 20 age components; (v) of all the methods, the logratio distance to the concordia composition produces the best results, in the sense that it yields nearly identical 206Pb / 238U and 207Pb / 206Pb age spectra without introducing an age bias. All the methods presented in this paper have been implemented in the IsoplotR toolbox for geochronology.
Una aproximación semiótica al estudio de los emojis
Authors: Vela Delfa Cristina
Published: December 2020

Los emojis son signos gráficos empleados con asiduidad en las interacciones digitales escritas. Su origen ha de situarse a finales de los años noventa del siglo pasado, aunque su popularidad ha ido en aumento desde que en 2011 fueran incorporados al teclado de Apple y a aplicaciones de mensajería instantánea como WhatsApp. En los últimos años los emojis se han convertido en uno de los temas centrales del estudio de la comunicación digital y han sido abordados desde distintos ámbitos y teorías. En este trabajo presentamos una caracterización semiótica de los emojis. Nos interrogamos sobre el lugar que estos elementos ocupan en la clasificación de los signos (índice, icono, símbolo) al tiempo que nos preguntamos sobre la manera en que se construye su interpretación y sobre las relaciones que entablan entre sí estas unidades comunicativas.
The Collective Agency of Language Teachers under the Scheme of Research Excellence: Using a social network approach
Authors: Tao Jian , Zhao Ke , Chen Xiuwen
Published: December 2020

This study adopted social network analysis (SNA) as a theoretical framework and methodological approach to understand the collective agency of a multilingual team of eight language teachers during their research practice in a Chinese university. As being guided by SNA that focuses on identifying social relationships and their impact, we used questionnaires and qualitative interviews to collect data and examine the emergence of collective agency. The data analysis revealed that the participants broke linguistic boundaries and engaged in cross-linguistic interactions. The findings further suggest that they offered complementary resources and emotional support for each other at individual, subgroup and group level. Based on the findings, this paper proposes a multi-layered understanding of collective agency to advance our knowledge of how to sustain collective agency. The findings point to the importance of addressing social interactions and relations in the emergence and enhancement of collective agency, so as to facilitate the professional development of language teachers.
Translanguaging in L3 Spanish Classrooms: Practices and Attitudes
Authors: Zhou Xiaozhou (Emily) , Huang XiaoLing , He Jili
Published: December 2020

Abstract. Research into pedagogical translanguaging in second/foreign language education has largely been focused on the interplay between two languages, one of which is usually English. Little attention has been paid to the practice of trilingual translanguaging (translanguaging between three languages), and how this can be helpful in the acquisition of a third language. This study, conducted in two Spanish as a third language classrooms in a Chinese university, aims to explore teachers’ translanguaging practices as well as the teachers’ and students’ attitudes to these practices. Analysis of data collected through audio-assisted classroom observation, interviews, and questionnaires reveals that teachers proactively and flexibly mobilize their multilingual resources in classroom talk. Students in general express positive attitudes towards teachers’ translanguaging practices, and express a wish to experience a greater amount of bilingual translanguaging between English (L2) and Spanish (L3). Meanwhile, having access to the views of L3 learners on teachers’ classroom talk proves to be a crucial component in the understanding of how L3 teaching and learning can take place in the most effective way. This study calls for further research into translanguaging practice in multilingual classrooms and its impact on students’ learning.
The impact of multilingual education policy on university language teachers’ professional development
Authors: Xu Hao , Pu Shi
Published: December 2020

This article reports on a case study that investigated language teachers’ perceptions of a newly launched multilingual programme in a Chinese university. Forty-one teachers from the university were interviewed. Data analysis reveals that the teachers perceived the new programme as an administration-dominated initiative that would impact on their teaching practice and research engagements. Particularly, they questioned the viability of its pedagogical innovation, and cast doubt on its implications in terms of what type of knowledge and research would be valued. They also viewed the new programme as a form of institutionalisation, resulting in the reallocation of resources within the university. These perceptions demonstrate how the innovative programme, imposed as a policy initiative, could influence the ecosystem of the whole university and affect its sustainable development.

Términos, contextos y significados de la sangre y del sacrificio en el Popol Vuh
Authors: Peretti Leda
Published: December 2020

En el Popol Vuh, los términos para “sangre” son kik’ y koma’j, y los principales tipos de actos sacrificiales son el autosacrificio, derivado de la raíz t’is, y el sacrificio humano, pus. Mientras el autosacrificio tiene la propiedad de despertar las efigies de los ídolos y renovar a los dioses, el sacrificio de seres humanos permite su revivificación. El mito establece, además, que el sacrificio pus no puede ser dirigido a los señores de Xib’alb’a, como tampoco lo puede ser la ofrenda del corazón y de la sangre pura. Al Inframundo van sus sustitutos y, en concreto, una sangre falsa, la savia de un árbol, kik’ jolomax, probablemente una metáfora de la sangre del ciclo femenino. Con respecto al juego de pelota, que tampoco puede ser una prerrogativa de Xib’alb’a, el examen de los episodios que mencionan los términos chaaj (“pelota” y “pelotear”) y kik’ (“pelota”) demuestra que ambos vocablos son sinónimos, dado que son metonímicos con respecto al sacrificio.
Hedge Funds, Arbitrage, and Timing
Authors: Lawson Daniel T. , Schwartz Robert L. , Thomas Seth D.
Published: December 2020

This paper is an extension of the work of Lawson and Schwartz (2018) which analyzes the risk-adjusted performance of hedge funds by employing a collection of four, five, seven, and eight-factor models. The purpose is to evaluate how well the top and bottom performing subset of hedge fund strategies have profited on known asset pricing anomalies during two unique time periods, 1994 to 2000 and 2001 to 2008. The bifurcation of the data into two distinct periods allows for a deeper exploration of the potential time-varying significance of estimated factor arbitrage. Our empirical testing suggests that both the top and bottom performing funds did utilize the asset growth anomaly to generate abnormal profits. Top performers tended to invest with a long emphasis on low asset growth, value firms while the bottom-five performing hedge fund strategies tested positive for a predilection towards going long small firms with low asset growth characteristics. Arguably, these outcomes probably align with the nature of the investment philosophy of each fund strategy. Interestingly, however, the time-varying significance of estimated coefficients for the value and returns momentum factors between the two distinct timeframes suggests either intentional or unintentional rotation between the use of available pricing anomalies and risk premiums.
Expanding socio-cultural identity research in sport psycho-logy: The potential of athlete autobiographies
Authors: McGannon Kerry R. , Smith Brett
Published: December 2020

Within the cultural sport psychology (CSP) genre, researchers have considered multiple and inter-secting athlete identity expression to enhance sport participation, inclusion and performance. The aim with the present paper was to build upon, and expand a CSP research agenda that focuses on socially constructed identities, through exploring narrative inquiry in conjunction with athlete autobi-ographies as data (re)sources. To accomplish this aim, we outline the central tenets of narrative in-quiry and convergences with CSP, followed by an overview of autobiography. We then draw on au-tobiography research from cultural studies and sport psychology in relation to two central areas of concern in CSP: gender issues with a focus on women and health and well-being issues in sport. We conclude with some aspirations for future research on autobiographies grounded in narrative inquiry, to expand a CSP research agenda.
