The bifurcation of the Nigerian cybercriminals: Narratives of the Economic and Financial Crimes Commission (EFCC) agents Publication date: July 2019 Source: Telematics and Informatics, Volume 40 Author(s): Suleman Lazarus, Geoffrey U. Okolorie Abstract While this article sets out to advance our knowledge about the characteristics of Nigerian cybercriminals (Yahoo-Boys), it is also the first study to explore the narratives of the Economic and Financial Crimes Commission (EFCC) officers concerning them. It appraises symbolic interactionist insights to consider the ways in which contextual factors and worldview may help to illuminate officers’ narratives of cybercriminals and the interpretations and implications of such accounts. Semi-structured interviews of forty frontline EFCC officers formed the empirical basis of this study and were subjected to a directed approach of qualitative content analysis. While prior studies, for example, indicated that only a group of cybercriminals deploy spiritual and magical powers to defraud victims (i.e. modus operandi), our data analysis extended this classification into more refined levels involving multiple features. In particular, analysis bifurcates cybercriminals and their operations based on three factors: educational-attainment, modus-operandi, and networks-collaborators. Results also suggest that these cybercriminals and their operations are embedded in “masculinity-and-material-wealth”. These contributions thus have implications for a range of generally accepted viewpoints about these cybercriminals previously taken-for-granted. Since these criminals have victims all over the world, insights from our study may help various local and international agencies [a] to understand the actions/features of these two groups of cybercriminals better and develop more effective response strategies. [b] to understand the vulnerabilities of their victims better and develop more adequate support schemes. We also consider the limitations of social control agents’ narratives on criminals.

Liking, sharing, commenting and reacting on Facebook: User behaviors’ impact on sentiment intensity Publication date: June 2019 Source: Telematics and Informatics, Volume 39 Author(s): Wandeep Kaur, Vimala Balakrishnan, Omer Rana, Ajantha Sinniah Abstract The form of communication on Facebook is not only limited to posting and commenting, but also includes sharing, liking and reacting. This study looks into how a Facebook diabetes community uses like, comment, shareand reaction in expressing themselves online and how these distinctions can be used to improve sentiment classification from text extracted from the said group. An intensity formula using those behaviors was proposed and experimentations conducted using Weka. The findings reveal a model encompassing user behaviors is able to determine sentiment more accurately compared to one without, with a 94.6 percentage of accuracy. Additional analyses reveal behaviors such as liking, commenting and sharing to contribute more to the sentiment classification compared to reacting. This further cement the need to include such behavioral aspects into sentiment polarity calculation, as it would help algorithms achieve better predictability when classifying sentiment.

Communicating social support online: The roles of emotional disclosures and gender cues in support provision Publication date: June 2019 Source: Telematics and Informatics, Volume 39 Author(s): Siyue Li, Kathryn D. Coduto, Lindsey Morr Abstract The anonymity of online support forums presents both benefits and challenges for online supportive communication. This study investigates how support seekers’ verbal disclosure of emotions and gender cues in their user profiles may affect viewers’ intended support provision. Participants were asked to view a mockup page containing a support seeker’s profile along with a support-seeking post. They were then instructed to complete a survey on their appraisal of the support seeker and their intentions to provide support to him/her. The study found that compared to support seekers who made limited emotional disclosures, those with high levels of emotional disclosures were perceived as more legitimate to seek support online, which, in turn, enhanced viewers’ intentions to provide that support. Further, gender-ambiguous support seekers were more likely to be attributed females if they made more rather than fewer emotional disclosures. However, support seekers’ gender cues did not moderate the impact of emotional disclosures on viewers’ intentions to provide emotional support. Implications of the findings are discussed.

Social interaction in MOOCs: The mediating effects of immersive experience and psychological needs satisfaction Publication date: June 2019 Source: Telematics and Informatics, Volume 39 Author(s): Jiaming Fang, Lufen Tang, Jingjing Yang, Min Peng Abstract Drawing on self-determination theory (SDT), the study proposes a model to reveal the underlying mechanism by which social interaction shapes learning engagement. This study uses survey data from 318 massive open online courses (MOOCs) learners and structural equation modeling method to assess the proposed model. The results show that immersive experience and three psychological needs satisfaction (i.e., competence, relatedness, and autonomy needs) fully mediate the effect of interaction on MOOC learning engagement. Psychological needs satisfaction demonstrates different effectiveness on learning engagement. Specifically, competence need satisfaction is shown to be the strongest predictor of MOOC learning engagement, while autonomy need satisfaction has the weakest effectiveness. Further, the results demonstrate that peer learning group identification strengthens the effect of social interaction on psychological needs satisfaction. The study is among the first to specifically focus on exploring the mechanism how psychological needs satisfaction mediates the relationship between social interaction and learning engagement and has important managerial implications for MOOC platform design and operation in order to facilitate MOOC engagement.

Smartphone use at tourist destinations: Interaction with social loneliness, aesthetic scope, leisure boredom, and trip satisfaction Publication date: June 2019 Source: Telematics and Informatics, Volume 39 Author(s): Wee-Kheng Tan, Kuan-Ju Lu Abstract Tourists often use smartphones while visiting tourist destinations. Many studies have examined the consequences of smartphone use at these destinations. This study considers tourists’ smartphone use due to their interaction with their travel companions, or in other words, social loneliness related issues, and the destination environment, or its aesthetic scope. Aesthetic scope is related to the experiential dimension and is concerned with diverse visual and auditory cues. This study also considers whether the number of visits to a destination moderates the relationships between social loneliness, aesthetic scope, smartphone use, leisure boredom, and trip satisfaction. Applying partial least square analysis on 246 responses from domestic tourists who visited Taitung in Taiwan, this study found that the contribution of smartphones to trip satisfaction is limited, and is often confined to applications that help tourists c have visited Taitung only once; these visitors use smartphones for functional and communication purposes. Additionally, it exerts a positive influence on those who have visited Taitung more than once; these visitors use a smartphone for entertainment purposes. Aesthetic scope serves as an antecedent of smartphone use for functional and communication purposes and only for visitors who have visited Taitung more than once.

Uncovering the relationship between point-of-interests-related human mobility and socioeconomic status Publication date: June 2019 Source: Telematics and Informatics, Volume 39 Author(s): Dong Li, Jiming Liu Abstract In a city or region, understanding the relationship between human mobility and socioeconomic status is critical to public policies formulation, urban design and marketing strategies development. Based on the available massive geo-located human data, existing studies focused almost exclusively on the position attributes (i.e. coordinates) of the locations visited by people to explore the relationship, however, they ignored the category attributes (e.g. restaurant or supermarket) of these locations which imply the purposes (e.g. eating or shopping) behind human movements. A location with coordinates and category information is usually referred to as a point-of-interest (POI). In this paper, we study the relationship between POIs-related human mobility and socioeconomic status at city level. Starting from the location-based social network (i.e. Foursquare) dataset, we find that the check-in numbers of location categories are correlated with socioeconomic indicators, either positively or negatively. To further validate these correlations, we develop and test a multi-task prediction framework based on POIs-related human mobility for forecasting socioeconomic indicators. Extensive experiments on the Foursquare dataset show that the socioeconomic indicators can be well predicted by our proposed framework. Our findings and methods are helpful for modeling human mobility and assessing socioeconomic status.
