Companies, like individuals, embrace social networks as a non-formal way to engage with their customers and suppliers, gather information about their online behavior, and offer personalized content. Both scholars and managers from various organizations looking to increase their competitive edge or market shares have an interest in the impact that social networks have on human behavior. Because of this, the current research seeks to investigate how users perceive a wide range of concepts related to using social networking sites, including fear of missing out (FoMO), social networking fatigue, information and communication overload, ubiquitous connectivity and peer communication, and privacy concerns. The authors also examined users’ intentions to continue using social networking sites despite the COVID-19 outbreak in order to ensure a more thorough understanding of the research topic. The findings aim to provide a better knowledge of how users see interaction on social networks in their daily lives as well as an overview of user perspectives on the terms mentioned above.","PeriodicalId":30022,"journal":{"name":"Studia Universitatis BabesBolyai Geologia","volume":"113 1","pages":"21 - 32"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80560825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effectiveness of government expenditure on economic growth depends on recipient sector of government expenditure. This study contributes to this research area by investigating the effect of government agricultural expenditure on economic growth in the Kingdom of Lesotho. The government of Lesotho identified the agricultural sector as a productive sector that is central to the achievement the economic growth goal and development plan. Descriptive statistics and inferential econometric techniques (ARDL, DOLS and VEC Granger causality) over time-series data for the period 1982-2019 were utilized in this study. The results suggest that while current level and pattern of government agriculture expenditure cannot stimulate the desired economic growth and prosperity in the country, domestic investment appear to be a stimulant of the desired economic prosperity. Consequently, any economic growth policy or strategy that is premised on government agricultural sector expenditure would fail. Thus study recommends that countries including Lesotho should prioritize sustained increase in domestic investment.","PeriodicalId":30022,"journal":{"name":"Studia Universitatis BabesBolyai Geologia","volume":"1 1","pages":"1 - 20"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88659832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It serves as a critical path to truth that shapes the policyholders’ ultimate perceptions of their insurers. Therefore, this study aimed at evaluating the relationships between claims settlement and risk attitudes, with specific reference to motor insurance policyholders in Lagos, Nigeria. The study adopted a cross-sectional survey research design. A survey based questionnaire was applied to 287 motor insurance policyholders. The findings-show that claims settlements are significant in attracting reasonable risk attitudes. The study recommends that motor insurance providers should put in place fascinating claims packages in order to boost the confidence level of the motoring communities. Government should rejuvenate and empower the motor insurance public complaint commission to address issues relating to motor insurance claims of either party in the motor insurance contract. Future research work could direct attention to insurance fraud issues emanating from the insurance claims settlement manual.","PeriodicalId":30022,"journal":{"name":"Studia Universitatis BabesBolyai Geologia","volume":"92 1","pages":"33 - 49"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83794223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We prove polynomial norm estimates for the solution $P_0^{-1}f$ of the form $$|P_0^{-1}f|_{H^{s_0 + k + mu}(M; E)} le C sum_{q=0}^{k} , | P_0^{-1} |^{q+1} ,|a |_{W^{|s_0|+k}}^{q} , | f |_{H^{s_0 + k - q}},$$ (thus in higher order Sobolev spaces, which amounts also to a parametric regularity result). The assumptions are that $E, F to M$ are Hermitian vector bundles and that $M$ is a complete manifold satisfying the Fr'echet Finiteness Condition (FFC), which was introduced in (Kohr and Nistor, Annals of Global Analysis and Geometry, 2022). These estimates are useful for uncertainty quantification, since the coefficient $a$ can be regarded as a vector valued random variable.
