This study was aimed to evaluate the Malay proficiency among students in Form Two especially non-Malay students and its relationship to academic achievement History. To achieve the purpose of the study there are two objectives, the first is to look at the difference between mean of Malay Language test influences min of academic achievement of History subject among non-Malay students in Form Two and the second is the relationship between the level of Malay proficiency and their academic achievement for History. This study used quantitative methods, which involved 100 people of Form Two non-Malay students in one of the schools in Klang, Selangor. This study used quantitative data were analyzed using descriptive statistics and statistical inference with IBM SPSS Statistics v22 software. This study found that there was a relationship between the proficiency of Malay language among non-Malay students with achievements in the subject of History. The implications of this study are discussed in this article.

UNSTRUCTURED Social media radically changed how information is consumed and reported and elicited a disintermediated access to an unprecedented amount of content. The world health organization (WHO) coined the term infodemics to identify the information overabundance during an epidemic. Indeed, the spread of inaccurate and misleading information may alter behaviours and complicate crisis management and health responses. This paper addresses information diffusion during the COVID-19 pandemic period with a massive data analysis on YouTube. First, we analyze more than 2M users’ engagement in 13000 videos released by 68 different YouTube channels, with different political bias and fact-checking indexes. We then investigate the relationship between each user’s political preference and her/his consumption of questionable/reliable information. Our results, quantified using information theory measures, provide evidence for the existence of echo chambers across two dimensions represented by the political bias and by the trustworthiness of information channels. Finally, we observe that the echo chamber structure cannot be reproduced after properly randomizing the users’ interaction patterns.

The Relationship

Originating from a pragmatic need to document strategies for modelling recurrent business scenarios, collections of workflow patterns have been proposed in the business process management community. The concrete applications of these workflow patterns in forward engineering have been extensively explored. Conversely, the core concern of business process archaeology is on recovering business process models from legacy systems utilizing reverse engineering methods. Little attention is given to the relationship between business process recovery and workflow patterns. This chapter aims to give a compact introduction to workflow control-flow patterns, workflow data patterns, workflow exception patterns, and service interaction patterns. In particular, the feasibility of combining workflow patterns with business process archaeology is examined by drawing on the research results of the MARBLE framework.

The Relationship

We revisit the panel data analysis of Acemoglu et al. (forthcoming) on the relationship between democracy and economic growth using state-of-the-art econometric methods. We argue that panel data settings are high-dimensional, resulting in estimators to be biased to a degree that invalidates statistical inference. We remove these biases by using simple analytical and sample-splitting methods, and thereby restore valid statistical inference. We find that debiased fixed effects and Arellano-Bond estimators produce higher estimates of the long-run effect of democracy on growth, providing even stronger support for the key hypothesis of Acemoglu et al.

Center Site

A comparative analysis of voluntary group interaction patterns within two “white ethnic” groups in St. Louis was conducted to investigate the relationship between levels of voluntary group participation and geographical sites of respective ethnic centers. Archival research, participant observation, and structured interviewing over a 12-month period were the methods employed to conduct case studies of both the Croatian and Czech ethnic communities. Utilizing an ecological framework, the findings suggest a degree of organizational activity is strongly dependent on the environmental adequacy of the ethnic center site. This paper describes how two varying external locations promote contrasting styles of secondary group involvement. Neighborhood stability supports ongoing participation in one pattern, but in the other, area transiency exacts merely occasional participation.

The Relationship

Many modern problems in medicine and public health leverage machine learning methods to predict outcomes based on observable covariates. In an increasingly wide array of settings, these predicted outcomes are used in subsequent statistical analysis, often without accounting for the distinction between observed and predicted outcomes. We call inference with predicted outcomes post-prediction inference. In this paper, we develop methods for correcting statistical inference using outcomes predicted with an arbitrary machine learning method. Rather than trying to derive the correction from the first principles for each machine learning tool, we make the observation that there is typically a low-dimensional and easily modeled representation of the relationship between the observed and predicted outcomes. We build an approach for the post-prediction inference that naturally fits into the standard machine learning framework, where the data is divided into training, testing, and validation sets. We train the prediction model in the training set,. We estimate the relationship between the observed and predicted outcomes on the testing set and use that model to correct inference on the validation set and subsequent statistical models. We show our postpi approach can correct bias and improve variance estimation (and thus subsequent statistical inference) with predicted outcome data. To show the broad range of applicability of our approach, we show postpi can improve inference in two totally distinct fields: modeling predicted phenotypes in re-purposed gene expression data and modeling predicted causes of death in verbal autopsy data. We have made our method available through an open-source R package: https://github.com/leekgroup/postpi

The Way

The focus of this panel is the material, organizational, and cultural conditions of digital markets. While the notion of economy refers to the more general production, distribution and allocation in society, the idea of markets represents specific contexts of economic exchange typical of capitalist economies (Carruthers & Babb, 2013). A more elaborate understanding of digital markets and their relationships with digital platforms can expand our understanding of the economic implications that specific types of platform architectures have at the level of economic interaction. The discussion takes as a starting point perspectives from economic sociology that emphasize how markets are embedded into broader social and societal structures (Granovetter, 2017) and conditioned upon cultural norms and conventions (Beckert, 2009). In addition, the panel is informed by the way economic sociology and STS have approached the material conditions of markets (Garcia-Parpet, 2007; MacKenzie, 2018) and the way these conditions frame and transform power relations and interaction patterns on specific markets. The panel consists of four papers that approach this issue from a range of perspectives: The relationship between platform architectures, open market strategies and the formation of ‘commodity money’ in the case of Steam, the relationship between platforms, markets, and state regulation in the case of Alibaba, the role of narratives, imagined futures, and collective action that frame patterns of buying and selling in global stock markets in the case of Gamestop shares and, finally, how the online engagement industry is organized in practice in the case of “click farms”.
