Twitch.tv has become an important platform for video streaming, especially of games, with more than 100 million monthly users. The structure of content on the platform, which merges live video feeds with chat rooms for user feedback, problematizes existing theoretical frameworks for understanding the roles and hierarchies of different types of users. Combined with efforts to monetize user engagement for the benefit of both platform owners and user-generators of content, there is a need for greater understanding of the new interaction paradigm introduced by the platform. The present study introduces a framework for systematic, quantitative analysis of user interactions in the chat rooms associated with Twitch channels, as well as a preliminary data set. Social network analysis techniques are used to analyse the centrality and homophily of different classes of users, and the theoretical significance of these observations is briefly discussed.

Common Principle

Adaptation is a common principle that recurs throughout the nervous system at all stages of processing. This principle manifests in a variety of phenomena, from spike frequency adaptation, to apparent changes in receptive fields with changes in stimulus statistics, to enhanced responses to unexpected stimuli. The ubiquity of adaptation leads naturally to the question: What purpose do these different types of adaptation serve? A diverse set of theories, often highly overlapping, has been proposed to explain the functional role of adaptive phenomena. In this review, we discuss several of these theoretical frameworks, highlighting relationships among them and clarifying distinctions. We summarize observations of the varied manifestations of adaptation, particularly as they relate to these theoretical frameworks, focusing throughout on the visual system and making connections to other sensory systems.

Twitter is used by different library types to communicate and engage with their community. This case study focuses on content choices in tweets and the level of engagement generated, in the context of two different types of library. The current study attempts to examine the contents of Library Twitter account of two libraries (academic and public) with the aim of evaluating in a comparative mode, their themes and levels of user engagement. This research used a mixed method research approach. For quantitative approach, this study analyzed 100 Tweets from each library, i.e. RMIT University Library and State Library of Victoria. Also, the study analyzed a number of tweets and levels of engagement by recording numbers of likes, replies and retweets. The qualitative aspect analyzed each Tweet to determine engagement level and type of content shared by each library. The results demonstrate that the public and academic libraries publish different types of content. The varied nature, audience and mandate of each library appear to influence the focus of their tweets. Also, the results show that the level of engagement is a factor of the numbers of tweets in any theme. The limitation of this study is the data set contained only 100 tweets for each library. Moreover, the number of users and registered library accounts had probably increased since the study was conducted.

Razzaque (2009) studied the role of gender in the ultimatum game by running experiments on students in various cities in Pakistan. He used standard confirmatory data analysis techniques, which work well in familiar contexts, where relevant hypotheses of interest are known in advance. Our goal in this paper is to demonstrate that exploratory data analysis is much better suited to the study of experimental data where the goal is to discover patterns of interest. Our exploratory re-analysis of the original data set of Razzaque (2009) leads to several new insights. While we re-confirm the main finding of Razzaque regarding the greater generosity of males, additional analysis suggests that this is driven by student subculture in Pakistan, and would not generalise to the population at large. In addition, we find strong effect of urbanisation. Our exploratory data analysis also offers considerable additional insights into the learning process that takes place over the course of a sequence of games.

The Relationship

In this article, the relationship between migration and inequality in India is analyzed on the basis of an understanding of the role of migration in creating inequalities in the economy and society of the state of Kerala. The Centre for Development Studies (CDS), Thiruvanathapuram, Kerala, conducts periodic Kerala Migration Surveys (KMSs) to monitor the current status of emigration from and return emigration to the state of Kerala. This data set is used to discover the dynamics of migration–inequality relationship in the state. The results of the study suggest that migration causes inequalities in mobility between migrant and non-migrant households and between different types of migrant households.

Positive Effect

While the use of vinegar to fi ght against infections and other crucial conditions dates back to Hippocrates, recent research has found that vinegar consumption has a positive effect on biomarkers for diabetes, cancer, and heart diseases. Different types of vinegar have been used in the world during different time periods. Vinegar is produced by a fermentation process. Foods with a high content of carbohydrates are a good source of vinegar. Review of the results of different studies performed on vinegar components reveals that the daily use of these components has a healthy impact on the physiological and chemical structure of the human body. During the era of Hippocrates, people used vinegar as a medicine to treat wounds, which means that vinegar is one of the ancient foods used as folk medicine. The purpose of the current review paper is to provide a detailed summary of the outcome of previous studies emphasizing the role of vinegar in treatment of different diseases both in acute and chronic conditions, its in vivo mechanism and the active role of different bacteria.

SummaryLiposomes of pure phospholipids were used in a modified APTT test system and the role of phosphatidyl serine (PS) in determining the sensitivity of the test system to the presence of lupus anticoagulants was assessed. Six consecutive patients with lupus anticoagulants and seven haemophiliacs with anticoagulants directed at specific coagulation factors, were studied. Increasing the concentration of phospholipid in the test system markedly reduced the sensitivity to lupus anticoagulants but had marginal effect on the specific factor inhibitors. The same effect was achieved when the content of PS alone was increased in a vehicle liposome of constant composition.The results suggest that the lupus anticoagulants can best be detected by a screening method using an APTT test with a reagent of low PS content. The use of a reagent rich in PS will largely abolish the lupus anticoagulant’s effect on the APTT. An approach using the two different types of reagent may facilitate differentiation of lupus inhibitors from other types of anticoagulant.

The aim of this track was to question the divide between the nature of knowledge understood as experiential in indigenous contexts and science as an objective transferable knowledge. However, these can co-exist and inform design practices within transforming social contexts. The track aimed to challenge the hegemony of dominant knowledge systems, and demonstrate co-existence. The track also hoped to make a case for other systems of knowledges and ways of knowing through examples from native communities. The track was particularly interested in, first, how innovators use indigenous and cultural systems and frameworks to manage or promote innovation and second, the role of local knowledge and culture in transforming innovation as well as the form of local practices inspired innovation. The contributions also aspired to challenge through examples, case studies, theoretical frameworks and methodologies the hegemony of dominant knowledge systems, the divides of ‘academic’ vs ‘non-academic’ and ‘traditional’ vs ‘non-traditional’.

The article is devoted to the study of evaluative tools used in modern French media in order to form the media image of a representative of the political elite. The techniques used in the creation of a memorial media portrait of Jacques Chirac (1932—2019), President of France from 1995 to 2007 are considered. The research material was the most prestigious French print media of various political orientations, published in late September — early October 2019 in connection with the death of the ex-President of the French Republic. The relevance of the research topic is dictated by the close attention of modern linguistics to axiological phenomena, differently presented in different types of discursive practices. The novelty of the study is due to the appeal to the analysis of the complex of evaluation tools used in the French print media when characterizing the former leader of the state during the nation’s farewell period. The estimated potential of the title of the article and its influence on the formation of the estimated vector of the entire text of the publication are shown. A systematic analysis of the assessment expression means, reflected in the memorial media portrait of the politician, is given. The factors that influenced the peculiarities of their use in this type of media portrait are revealed.

Uncertainty Estimates

Heisenberg exchange spin coupling between metal centers is essential for describing and understanding the electronic structure of many molecular catalysts, metalloenzymes, and molecular magnets for potential application in information technology. We explore the machine-learnability of exchange spin coupling, which has not been studied yet. We employ Gaussian process regression since it can potentially deal with small training sets (as likely associated with the rather complex molecular structures required for exploring spin coupling) and since it provides uncertainty estimates (“error bars”) along with predicted values. We compare a range of descriptors and kernels for 257 small dicopper complexes and find that a simple descriptor based on chemical intuition, consisting only of copper-bridge angles and copper-copper distances, clearly outperforms several more sophisticated descriptors when it comes to extrapolating towards larger experimentally relevant complexes. Exchange spin coupling is similarly easy to learn as the polarizability, while learning dipole moments is much harder. The strength of the sophisticated descriptors lies in their ability to linearize structure-property relationships, to the point that a simple linear ridge regression performs just as well as the kernel-based machine-learning model for our small dicopper data set. The superior extrapolation performance of the simple descriptor is unique to exchange spin coupling, reinforcing the crucial role of choosing a suitable descriptor, and highlighting the interesting question of the role of chemical intuition vs. systematic or automated selection of features for machine learning in chemistry and material science.

Role Of Information

Misinformation often continues to influence people’s cognition even after corrected (the ‘continued influence effect of misinformation’, the CIEM). This study investigated the role of information relevance in the CIEM by questionnaire survey and experimental study. The results showed that information with higher relevance to the individuals had a larger CIEM, indicating a role of information relevance in the CIEM. Personal involvement might explain the effects of information relevance on the CIEM. This study provides insightful clues for reducing the CIEM in different types of misinformation and misinformation with varying relevance.
