Precise Marketing Strategy Optimization of E-Commerce Platform Based on KNN Clustering

With the development of computer technology and the arrival of the era of artificial intelligence, the analysis of user demand bias is of great significance to the operation optimization of e-commerce platforms. Combined with CS domain signaling data, IP packet data of PS domain, and customer CRM data provided by operators, this research studies each dimension index of operator user portrait, after that the operator user portrait platform is divided into some individual subunits, and then the corresponding data mining technology is carried out to study the implementation scheme of each subunit. The system can process and mine multidimensional data of operators’ users and form user portraits on the basis of user data aggregation. Finally, based on the operator user portrait platform studied in this paper, the operator user data are analyzed from both the user’s mobile phone use behavior and user consumption behavior. Furthermore, the application value of this research in the precision marketing and personalized service of operators is illustrated.

Analisis Kontrol Diri Siswa Saat Belajar dari Rumah dalam Menggunakan Handphone pada Masa Pandemi COVID-19

This research is motivated by indications that students have not been able to control themselves in the use of mobile phones, so it can negatively affect students. This study aims to analyze students' self-control when learning from home in using mobile phones during the Covid-19 outbreak. This study is a type of descriptive quantitative research with a research population of all students of State Junior High School 3 Sungai Penuh numbering 149 people, then the sample of this study was taken with total sampling techniques. The study data was collected using a scale of students' self-control in mobile phone use, then analyzed data using descriptive statistics. The results showed that the level of self-control of students in using mobile phones during the Covid-19 pandemic in aspects of self-control, diligent despite many obstacles, behaving according to rules and norms, controlling emotions, and the ability to adjust to be in the moderate category. For that, to the next researcher, it is expected to conduct research by conducting treatment to research subjects so that the ability of students in controlling themselves becomes better, especially in the use of mobile phones

Mobile phone-assisted agricultural extension services: User competency and usage frequency in eastern Ghana

Adoption studies have mainly focused on econometric and quantitative modelling that usually assume smallholder farmers competently adopt agricultural technologies. This study provides novel insights on user competency and frequency of usage of mobile telephony for agricultural extension services among smallholder farmers and agricultural extension agents (AEAs) and key factors that impede the adoption process. The study examined users’ competencies and mobile phone usage frequency for access and delivery of agricultural extension services in Eastern Ghana. A multi-stage sampling procedure was used to select 95 AEAs and 330 smallholder farmers in five districts of the Eastern region of Ghana and data were collected through semi-structured interviews. Descriptive statistics, Pearson correlation and regression analyses were performed to analyse the data. Results showed substantial differences between AEAs and smallholder farmers’ competency in the use of mobile phones for agricultural extension services. Socio-demographic characteristics of smallholder farmers and AEAs correlated with usage frequency of mobile phones for access to extension services and delivery. Educational level, amount of weekly expenditure of money on mobile phone use, mobile phone network quality, income level, and age of both AEAs and smallholder farmers had positive and significant correlations with frequency of usage of mobile phones. User competency differentially impacts the frequency of mobile phone use in agricultural extension services between AEAs and smallholders. High call tariffs and access to recharge cards are major challenges in using mobile phones for agricultural extension in the study areas. The study shows components of the adoption theory of compatibility, and complexity where an innovation fits within the socio-cultural framework and perceived difficulty of use. Thus, the frequent use of voice calls is indicative of early stages of the diffusion process and may diversify into other applications in the future. Farmer-based organisations should be resourced to support training of farmers to use mobile phones to improve access to agricultural information dissemination. Integrating voice-based agricultural information services (IVRs) into the current SMS-based agricultural extension services in Ghana could potentially boost extension service delivery to smallholder farmers in the Eastern region and across the country. The Ministry of Food and Agriculture may partner with key stakeholders and mobile service providers to offer hands-on capacity building to smallholder farmers and AEAs in video calling/conferencing, multimedia service, and social media to enhance their competencies for improved agricultural extension services.

The Effect of Loneliness in Psychological and Behavioral Profile among High School Students in Spain

Loneliness is a distressing feeling that can be a barrier to a student’s development and affect their mental health. This research aimed to analyse the effects of loneliness on psychological and behavioral factors among students aged 12–19 years in Spain. Loneliness, experiential avoidance, psychological inflexibility, physical activity, mobile phone use, and smoke habits were analysed in a sample of 110 men and 122 women assigned into two groups depending on their loneliness levels: higher loneliness group (HLG) and lower loneliness group (LLG). Results showed that experimental avoidance and psychological inflexibility were related with loneliness (r = 0.471; p = 0.000). Experiential avoidance and psychological inflexibility were higher in HLG than LLG. Regarding the use of mobile phones and smoking habits, LLG presented significantly higher values than HLG. Higher age correlated with lower loneliness values (r = −0.155; p = 0.017). The present research found how students with higher loneliness presented higher experiential avoidance and psychological inflexibility and lower age, use of mobile phone, and smoking habits. These findings reveal the importance of considering multiple social behaviours when examining adolescent mental health factors.

Mobile Networked Creativity: Developing a theoretical framework for understanding creativity as survival

Mobile networked creativity is an emergent practice that arises from the ongoing relationships among people and people with technologies—or networked resources. In this paper, we propose a concept of creativity as emerging from serendipity and mobility. We focus on how unplanned or emergent uses of digital technologies reveal how creative practices emerge, particularly in the context of mobile phone use where people are also physically mobile and yet connected via the internet. This concept of creativity as a constant process of becoming is a “recursive organization” that can be seen in groups such as migrants, or people living in disenfranchised communities that survive in make-shift locations such refugee camps or slums. Contrary to the affluent and capitalistic-embedded traditional ideas of creativity, mobile networked creativity is a practice that is most often found in situations of economic hardship, power imbalances, and immobilities.

High Throughput Metagenomic Analysis Exposes Mobile Phones as Potentially Hazardous Microbial Platforms Warranting Robust Public Health and Biosecurity Protocols

Introduction. Advancements in technology and communication have revolutionised the 21st century with the introduction of mobile phones and smartphones. These phones are known to be platforms harbouring microbes with recent research shedding light on the abundance and broad spectrum of organisms they harbour. Mobile phone use in the community and in professional sectors including health care settings is a potential source of microbial dissemination.Aim. To identify the diversity of microbial genetic signature present on mobile phones owned by hospital medical staff.Methods. Twenty-six mobile phones of health care staff were swabbed. DNA extraction for downstream next generation sequencing shotgun metagenomic microbial profiling was performed. Survey questionnaires were handed to the staff to collect information on mobile phone usage and users’ behaviours.Results. A total of 11259 organisms derived from 26 phones were found with 2096 genes coding for antibiotic resistance and virulent factors. These organisms corresponded to 5717 bacteria, 675 fungi, 93 protists, 320 viruses, 4456 bacteriophages. The survey of medical staff showed that 46% (12/26) of the participants used their mobile phones in the bathroom.Discussion/conclusion. Mobile phones are vectors of microbes and can contribute to microbial dissemination and nosocomial diseases worldwide. As fomites, mobile phones that are not decontaminated may pose serious risks for public health and biosecurity.
