Use Of Social Media

In recent years, the pervasive use of social media has generated huge amounts of data that starts to gain a lot of attentions. Each social media source utilizes different data types such as textual and visual. For example, Twitter1 is for a short text message, Flickr2 is for images and videos, and Facebook3 allows all of these data types. It is highly desired to find patterns of social media users from such different data formats. With the use of data mining techniques, the social media data opens a lot of opportunities for researchers. Despite of its short history, social media mining has become very active research area. This paper provides a comprehensive survey on recent research on social user mining. In particular, the survey focuses on two aspects: (1) social user mining based on data types, such as textual, visual, and both textual and visual information, and (2) social user mining based on mining techniques. In addition, we present our current research on social user mining as well as its future directions.

Acknowledging the widespread use of social media and the exponential growth of digital technology, a number of reputable organizations and small and medium-sized enterprises (SMEs) have shifted their traditional marketing tools to approach new markets for the growth of their businesses. Such companies have introduced their business over social media in order to gain greater attention from the consumers. However, the major concern addressed regarding how products and services are promoted online is regarding sustainable marketing. It is explored that most of the consumers tend to view online businesses by visualizing essential factors that reflect sustainability and thus, SMEs have started to analyze specific web atmospheric cues, which contribute in developing social media according to consumer behavior and their perceptions. To assess the research area, the following study is performed to understand possible measures that are significant in bridging business and consumer needs. This research incorporates a quantitative research method for gathering specific data by using questionnaires. From the findings of the research, it is analyzed that consumers are likely to perceive and give attention to social media by analyzing specific cues, including visuals, ethics, information, social, and security. It is concluded that SMEs could foster their online businesses by adopting effective sustainable marketing strategies aligned according to specific web atmospheric cues.

Abstract The use of social media platforms as an educational tool to promote awareness has become increasingly popular as technology advances. Twitter is a microblogging, social media platform in which users share short, text-based posts (“tweets”) that can contain hyperlinked articles, web-pages, pictures, and more. 79% of the 336 million current monthly twitter users are international, suggesting Twitter serves as a tool allowing international connection via the rapid spread of information worldwide. Simplur Signals (Simplur LLC) was used to perform a retrospective analysis of the use of #Geriatrics on Twitter. Data was collected from Oct. 13th, 2010 through Jun. 5th, 2018. Spam and unknown accounts were excluded from the data set before analysis. Manual analysis was performed to qualitatively assess tweet content of the top 200 Retweets by Impressions. A total of 65,002 tweets were shared during the selected time frame. Tweet activity rose to a high in Year 5 (17,206) but has declined since. The majority of the top 100 influencers were doctors (57.4%). Regarding tweet content, most discussions focus on increasing awareness and promoting advocacy (30%) as well as sharing research related to the practice of geriatrics (23.5%). With its widespread use and lack of international boundaries, Twitter serves as an effective platform in informing and increasing awareness about geriatrics and other medical specialties.

Silicon photomultipliers (SiPMs) offer advantages such as lower relative cost, smaller size, and lower operating voltages compared to photomultiplier tubes. A SiPM’s readout circuit topology can significantly affect the characteristics of an imaging array. In nuclear imaging and detection, energy, timing, and position are the primary characteristics of interest. Nuclear imaging has applications in the medical, astronomy, and high energy physics fields, making SiPMs an active research area. This work is focused on the circuit topologies required for nuclear imaging. We surveyed the readout strategies including the front end preamplification topology choices of transimpedance amplifier, charge amplifier, and voltage amplifier. In addition, a review of circuit topologies suitable for energy, timing, and position information extraction was performed along with a summary of performance limitations and current challenges.

Interpretative Model

This paper aims at contributing to financial reporting literature by proposing a conceptual interpretative model to analyse the corporate use of social media for financial communication purposes. In this perspective, the FIRE model provides a framework to study social media shifting the focus on the distinctive features that might enhance web investor relations. The model highlights these features through four building blocks: (i) firm identity (F); (ii) information posting (I); (iii) reputation (R); and (iv) exchange and diffusion (E). They represent key aspects to explore corporate communication activities and might offer a framework to interpret to what degree corporate web financial reporting exploits the potential of social media. Accordingly, the paper proposes metrics based on this model aimed at capturing the interactivity of corporate communications via social media, with a particular focus on web financial reporting. It tries to show the potential of this model by illustrating an exploratory empirical analysis investigating to what extent companies use social media for financial reporting purposes and whether firms are taking advantage of Twitter distinctive features of interaction and diffusion.

Traditional Approaches

Image quality assessment has been a very active research area in the field of image processing, and there have been numerous methods proposed. However, most of the existing methods focus on digital images that only or mainly contain pictures or photos taken by digital cameras. Traditional approaches evaluate an input image as a whole and try to estimate a quality score for the image, in order to give viewers an idea of how “good” the image looks. In this paper, we mainly focus on the quality evaluation of contents of symbols like texts, bar-codes, QR-codes, lines, and hand-writings in target images. Estimating a quality score for this kind of information can be based on whether or not it is readable by a human, or recognizable by a decoder. Moreover, we mainly study the viewing quality of the scanned document of a printed image. For this purpose, we propose a novel image quality assessment algorithm that is able to determine the readability of a scanned document or regions in a scanned document. Experimental results on some testing images demonstrate the effectiveness of our method.

This article aims to explain maqâṣid al-Qur’ân according to M. Quraish Shihab and its application in interpreting verses related to the use of social media. The problem that will be answered in this article covers two main issues, namely how the perspective of maqâṣid al-Qur’ân according to M. Quraish Shihab and how it is applied in interpreting the verses of the use of social media. The method used is the thematic method, namely discussing verses based on themes. Fr om this study the authors concluded that according to M. Quraish Shihab there are six elements of a large group of universal goals of the al-Qur’ân, namely strengthening the faith, humans as caliphs, unifying books, law enforcement, callers to the ummah of wasathan, and mastering world civilization. The quality of information lies in the strength of the monotheistic dimension which is the highest peak of the Qur’anic maqâṣid. M. Quraish Shihab offers six diction which can be done by recipients of information in interacting on social media. Thus, it aims to usher in the knowledge and understanding of what is conveyed in carrying out human mission as caliph, enlightenment through oral and written, law enforcement, unifying mankind and the universe to the ummah of wasathan, and mastery of world civilization

Use Of Social Media

Social media as a communication tool has enabled governments around the world to interact with citizens for customer service, access to information and to direct community involvement needs. The trends around the world show recognition by governments that social media content may constitute records and should be managed accordingly. The literature shows that governments and organisations in other countries, particularly in Europe, have social media policies and strategies to guide the management of social media content, but there is less evidence among African countries. Thus the purpose of this paper is to examine the extent of usage of social media by the Botswana government in order to determine the necessity for the governance of liquid communication. Liquid communication here refers to the type of communication that goes easily back and forth between participants involved through social media. The ARMA principle of availability requires that where there is information governance, an organisation shall maintain its information assets in a manner that ensures their timely, efficient and accurate retrieval. The study adopted a qualitative case study approach where data were collected through documentary reviews and interviews among purposively selected employees of the Botswana government. This study revealed that the Botswana government has been actively using social media platforms to interact with its citizens since 2011 for increased access, usage and awareness of services offered by the government. Nonetheless, the study revealed that the government had no official documentation on the use of social media, and policies and strategies that dealt with the governance of liquid communication. This study recommends the governance of liquid communication to ensure timely, efficient and accurate retrieval when needed for business purposes.

Use Of Social Media

The use of social media platforms has over the years become a veritable tool for individuals, groups, institutions and corporate bodies for the promotion of health and wellness. In recent times, social media has become one of the most potent agents of the media through which health issues are addressed as well as generated and disseminated to different populations in society. The study was conducted to examine social media use and students’ health lifestyle modification in the University of Calabar, Nigeria. It sought to determine the extent to which students’ use of social media (Facebook, Twitter, and WhatsApp) influences the modification of their health-related lifestyles such as eating habits, sexual behaviour, cigarette and alcohol consumption, drug use and the engagement in fitness activities. The study adopted a randomized descriptive survey design and used a sample of 300 undergraduate students. The questionnaire was the main instrument used for collection of data while simple percentages and means were used to determine the difference between the expected mean of 2.50 and the observed means across various items in the questionnaire. The results showed that apart from Twitter, social media use by University of Calabar students has significantly influenced the modification of their health lifestyles. Since social media has become a veritable tool for the promotion of positive health lifestyle, effort should be made by government through the health sector to create more awareness among students and the entire population of social media users, on the health benefits accruing from use of social media.
