The telecommunication sector has been developed rapidly and with large amounts of data obtained as a result of increasing in the number of subscribers, modern techniques, data-based applications, and services. As well as better awareness of customer requirements and excellent quality that meets their satisfaction. This satisfaction raises rivalry between firms to maintain the quality of their services and upgrade them. These data can be helpfully extracted for analysis and used for predicting churners. Researchers around the world have conducted important research to understand the uses of Data mining (DM) that can be used to predict customers' churn. This paper supplies a review of nearly 73 recent journalistic articles starting in 2003 to introduce the different DM techniques used in many customerbased churning models. It epitomizes the present literature in the field of communications by highlighting the impact of service quality on customer satisfaction, detecting churners in the telecoms industry, in addition to the sample size used, the churn variables used and the results of various DM technologies. Eventually, the most common techniques for predicting telecommunication churning such as classification, regression analysis, and clustering are included, thus presenting a roadmap for new researchers to build new churn management models.

The COVID-19 pandemic that has hit the world in the year 2020 has put a strain on our ability to cope with events and revolutionized our daily habits. On 9 March, Italy was forced to lockdown to prevent the spread of the infection, with measures including the mandatory closure of schools and nonessential activities, travel restrictions, and the obligation to spend entire weeks in the same physical space. The aim of this study was to assess the impact of the COVID-19 pandemic and lockdown measures on quality of life (QoL) in a large Italian sample, in order to investigate possible differences in QoL levels related to both demographic and pandemic-specific variables. A total of 2251 Italian adults (1665 women, mainly young and middle adults) were recruited via a snowball sampling strategy. Participants were requested to answer to an online survey, which included demographic and COVID-related information items, and the World Health Organization Quality of Life BREF questionnaire (WHOQOL-BREF). The results showed statistically significant differences in QoL depending on a number of variables, including sex, area of residence in Italy, and being diagnosed with a medical/psychiatric condition. To our knowledge, this is the first study to assess QoL during COVID-19 pandemic in Italy, therefore the present findings can offer guidelines regarding which social groups are more vulnerable of a decline in QoL and would benefit of psychological interventions.

Digital technologies, ubiquitous in our daily life, have radically changed the way we work, communicate, and consume in a short period of time. They affect all components of quality of life: well-being, work, health, education, social connections, environmental quality, the ability to participate and govern civil society, and so on. Digital transformation creates both opportunities and serious risks to the well-being of people. Researchers and statistical agencies around the world are facing a major challenge to develop new tools to analyze the impact of digital transformation on the well-being of the population. The risks are very diverse in nature and it is very difficult to identify the key factor. All researchers conclude that secure digital technologies significantly improve the lives of those who have the skills to use them and pose a serious risk of inequality for society, as they introduce a digital divide between those who have the skills to use them and those who do not. In the article, the author examines the risks created by digital technologies for some components of the quality of life (digital component of the quality of life), which are six main components: the digital quality of the population, providing the population with digital benefits, the labor market in the digital economy, the impact of digitalization on the social sphere, state electronic services for the population and the security of information activities. The study was carried out on the basis of the available statistical base and the results of research by scientists from different countries of the world. The risks of the digital economy cannot be ignored when pursuing state social policy. Attention is paid to government regulation aimed at reducing the negative consequences of digitalization through the prism of national, federal projects and other events.

The purpose of this study is to examine the impact and the electronic service quality of the national zakat management information system (SIMBA) on the national zakat collection. This paper uses a multiple regression analysis in its explorative attempt to illustrate the impact of SIMBA implementation on the national zakat collection. It shows that SIMBA is positive and significantly impact the national zakat collection as well as the human development index that is used as a proxy for the human resource management quality of zakat institutions in the respective city. Nonetheless, the population is negative and significant to the zakat collection as endemic poverty and reluctance to pay zakat are indicated as the reasons. Moreover, this study has succeeded in adapting and conducting e-service quality survey to zakat information system realm. All the tests prove that the instrument in this study has a high degree of reliability and validity. The results show that some of the demographic factors significantly impact the perceived performance of SIMBA. Multiple regression analysis that is conducted in this study shows that e-service quality dimension is positive and significant towards SIMBA’ overall quality, perceived value, and loyalty intention. This study contributes to the zakat management system literature, especially in the impact of the national zakat information system, which is pivotal in enhancing zakat collection and poverty alleviation program funded by zakat.

The article highlights the main steps in the formation of compulsory licensing mechanism before the establishment of the World Trade Organization, and analyzes the main provisions of this mechanism implementation under the TRIPS Agreement and the Doha Declaration. Based on the analysis of examples from different regions of the world, the article determines the main advantages of using compulsory licensing with regard to expand of access to medicines, possible impact on quality of the medicinal products being produced and the investment attractiveness of the countries applying this mechanism are assessed. The purpose of this article is to analyze the main approaches to the implementation of compulsory licensing in order to determine the most effective strategy for using this mechanism in the Russian Federation in order to expand the availability of drug therapy for the treatment of life-threatening diseases. Based on the impact of compulsory licensing implementation, the author concludes that it does not correspond to the objectives of the Russian pharmaceutical industry development identified as a priority by Russian Government. Despite a possibility of using compulsory licensing under regulation of many countries, this mechanism is implemented rarely. A possibility of issuing a compulsory licensing is a strong argument in price negotiations with producers. According to the authors position, implementation of compulsory licensing has to be preceded by cost containment mechanism, primarily based on negotiations with producers.

The aim of this study was to investigate the impact of being away from home on the well-being of international and domestic UK university students as a function of demographic factors, course load, support, personality, healthy lifestyle, and their employment of pre-planning and being at university strategies. A total of 510 students (n = 391 international and 117 British) completed an on-line survey to record demographic details and measure their well-being, quality of university life, and their being away from home strategies. The findings showed that International students reported greater quality of university life and used more pre-departure strategies; the female students reported a significantly more negative well-being and higher course demand than their male peers. A regression analysis showed that positive well-being was predicted by a positive personality, a healthy lifestyle, control and support for academic work, quality of university life and employing well-being strategies (using technology without over-reliance on it and the ability to unwind from study). Negative well-being, on the other hand, was predicted by a less positive personality and a less healthy lifestyle, a higher course demand, less control and support for academic work and less quality of university life. Moreover, the regression analysis showed that international students who employed more pre-departure strategies showed less negative well-being.

Purpose – This article aims to investigate perceptions of Turkish nurses on the impact of accreditation on quality of care and the effect of accreditation on quality results. Design/methodology/approach – This study was performed as a cross-sectional, questionnaire-based survey on 258 nurses who started working in the hospital before it was accredited and continued to work during and after accrediation and who therefore knew both the hospital's pre-accrediation and post-accreditation periods. In this study, descriptive statistical analyses (means and standard deviations) were carried out to explore the views of the participants on “quality results,” “benefits of accreditation” and “participation of employees.” “Quality results” was considered to be the dependent variable, while “benefits of accreditation” and “participation of employees” were accepted as the independent variables. The relationship between the dependent variable and the independent variables was tested using Pearson correlation and multiple regression analysis. External patient satisfaction data collected by the quality department of the hospital before and after accreditation were also investigated. Findings – It was found that nurses had generally high scores for the items concerning the benefits of accreditation. There was a statistically significant positive correlation between the dependent variable (quality results) and the independent variables (benefits of accreditation and participation of employees). Regression analysis indicated that R2=0.461 and the extent to which the independent variables explained the dependent variable was 46.1 per cent, which is a high rate. Patient satisfaction scores increased after accreditation. Practical implications – Our study suggest that providing support for nurses, especially nurses with administrative responsibilities and incorporating employees into the process are important for exercising quality standards. Originality/value – Hospital accreditation has a positive impact on quality results especially on quality of care provided to patients and patient satisfaction. Study findings could guide policy makers and hospital managers in Turkey and in other countries who are preparing or implementing accreditation.
