Reasons for betel quid chewing amongst dependent and non-dependent betel quid chewing adolescents: a school-based cross-sectional survey

Background: Betel quid (BQ) chewing in children is initiated in their adolescence. It is pivotal to understand adolescents’ reasons behind chewing BQ. In this study, we aimed to evaluate the reasons for BQ chewing amongst adolescents using reasons for betel quid chewing scale (RBCS) and their associated dependency on it. Methods: This is a cross-sectional school based survey. Out of 2200 adolescents from 26 schools of Karachi, 874 BQ chewers were assessed for their reasons of BQ chewing and dependency on it. Regression analyses were employed to report crude and adjusted (after adjusting for all reasons of BQ chewing) effect sizes with 95% confidence interval and P-value was set significant at < 0.05. Results: Students who believed that BQ chewing relaxes them (stimulation construct) were twice as likely to be dependent on BQ (OR = 2.36, 95% CI (1.20–4.65) as compared with others. Participants who thought it eases their decision making (stimulation construct), were sizably more likely to be dependent on BQ (OR = 9.65, 95% CI (4.15–22.43) than those who did not consider ease in decision making important. Adolescents who considered not chewing as rude (social/cultural construct), were thrice more likely to be dependent on BQ (OR = 2.50, 95% CI (1.11–5.63) than others. Conclusions: Stimulation remained fundamental chewing reason followed by social/cultural trigger amongst adolescents. Any future intervention may get favorable results if it addresses ways to overcome stimulation and social/cultural barriers that are strongly associated with BQ chewing and dependency

The attitudes, feelings and experiences of online gamers: a qualitative analysis

The playing of massively multiplayer online role-playing games (MMORPGs) is now a highly popular leisure activity. The present study set out to explore the attitudes, experiences, and feelings of online gamers. The study entailed 71 interviews with online gamers (52 males, 19 females) from 11 different countries. Six main themes emerged from the analyses of the interview transcripts: (a) online gaming and integration into day-to-day lives; (b) online gaming, excessive play, and problems; (c) addiction; (d) psychosocial impact of online gaming; (e) online gaming, dissociation, and time loss; and (f) online gaming and the alleviation of negative feelings and mood states. These findings specifically showed how gamers used MMORPGs to alleviate negative feelings and provided detailed descriptions of personal problems that had arisen due to playing MMORPGs. The implications of these findings are discussed in relation to previous qualitative and quantitative research in the area

Smartphone addiction and associated psychological factors

The use of smartphone technology has increased drastically resulting in a risk of addiction to certain web applications, such as social networking sites (SNS) that are easily accessible via smartphones. A major concern regarding the increased use of SNS sites is the risk of an increase in narcissism amongst users of SNS. The present study examined the relationship between smartphone use, narcissistic tendencies, and personality as predictors of smartphone addiction. A self-selected sample of 256 smartphone users (M = 29.2; SD = 9.49) completed an online survey. The results revealed that 13.3% of the sample was classified as addicted to smartphones. Regression analysis revealed that narcissism, openness, neuroticism, and age were linked to smartphone addiction. Therefore, it is suggested that smartphones encourage narcissism, even in non-narcissistic users. Future research requires more in-depth qualitative data, addiction scale comparisons, and comparison of use with, and without, SNS access. Further, it is advised that prospective buyers of smartphones be pre-warned of the potential addictive properties of new technology

An exploratory study of Facebook intensity and its links to narcissism, stress, and self-esteem

Facebook use has become a popular social activity. More intensive use of Facebook may increase the risk of health problems. Research suggests that high levels of stress and low levels of self-esteem are linked to Facebook intensity usage, however, these findings have been inconsistent, as studies also suggest the opposite or no links at all. This exploratory study examined whether narcissism, stress and self-esteem could predict Facebook intensity, and whether a short session on Facebook could produce immediate psychological effects. A sample of 163 Facebook users completed an online survey, engaged in a short Facebook session and then completed another online survey. Regression analysis revealed that narcissism, stress and self-esteem were found to significantly predict Facebook intensity with stress being a significant predictor within the model. Facebook use significantly increased self-esteem scores amongst the participants. The findings are discussed in relation to previous research and theory.N/

Betel quid dependency and associated intrapersonal, interpersonal, and environmental factors among adolescents: a school-based cross-sectional survey

Background: Betel quid (BQ) is one of the fourth most commonly used substance globally. Though BQ is a psycho-active substance, yet little has been explored regarding dependency on it particularly among adolescents. Objectives: Therefore, in this study, we aimed to determine adolescents' dependency on BQ, along with their intrapersonal, interpersonal and environmental determinants of dependency. Methods: This cross-sectional study focused on 2200 school-going adolescents of Karachi, Pakistan in 2016. Primary outcome was dependency on BQ among adolescents. Both univariate and multivariate regressions were used to estimate crude and adjusted odds ratios (after adjustments for all intrapersonal, interpersonal, and environmental factors) with 95% confidence level. Results: Out of 2200 students, 874 (39.7%) were found to be BQ users amongst whom 69 (7.9%) were dependent on BQ. Comparing the groups with only areca nut users as reference category, betel quid with tobacco additives chewers were considerably dependent (OR = 14.08, 95% CI 3.64–54.16). The individuals who chewed >5 chews per day (OR = 1.87, 95% CI 1.08–3.29) and chronic users (>1year) (OR = 2.02, 95% CI 1.09–3.74) were more likely to be dependent. Older students (>12 years) (OR = 2.12, 95% CI 1.06–4.23), and who studied in government schools were significantly dependent (OR = 3.32, 95% CI 1.80–6.10) than those who studied in private schools. Conclusions: In conclusion, intrapersonal characteristics like more than 5 chews per day, chronic chewers of more than a year, BQ with tobacco chewers, older adolescents and children studying in government schools were significantly associated with BQ dependency

Individual, social and environmental determinants of smokeless tobacco and betel quid use amongst adolescents of Karachi: a school-based cross-sectional survey

Background: With 600 million people using betel quid (BQ) globally, and smokeless tobacco (SLT) use being more wide-spread; the duo is an uphill public health concern in South Asian countries. SLT and/or BQ use increases the risk for morbidity and mortality from oral cancer. Because SLT and/or BQ use is initiated during adolescence, it renders this group more vulnerable; and particular attention is needed to curb SLT and/or BQ use to reduce related disease burden. We aimed to observe the differential individual, social and environmental features amongst SLT and/or BQ users to determine the key influencers of its use in adolescents. Methods: This study was a cross-sectional survey of 2140 adolescents from secondary schools of Karachi, Pakistan. The main outcome measure was SLT and/or BQ use based on their consumption in the past 30 days. Univariate and multivariate regression binary logistic analyses were employed while reporting results in both crude form and adjusted odds ratio (after adjusting for all remaining individual, social and environmental level variables) with 95% confidence level. A p-value of < .05 was considered significant for all analyses. Results: The overall prevalence of SLT and/or BQ use was 42.6% (n = 912) of the total sample. The SLT and/or BQ consumer group had more males than females. A significant proportion of user (n = 558, 61.2%) was found in co-education schools. Students whose peers (OR = 6.79, 95% CI 4.67–9.87, p-value <0.001) and/or either of the parents (OR = 2.16, 95% CI 1.73–2.65, p-value <0.001) used SLT and/or BQ, alongside, adolescents who had not attended knowledge based sessions in schools regarding harmful effects of SLT and/or BQ were more likely to consume it. It’s availability with outside school hawkers increased the odds of its use by 6 times, as indicated by both univariate and multivariate models after adjusting for the remaining variables. Conclusion: In conclusion, students studying in co-education, parents and peers use, lack of knowledge based sessions on harmful health effects of SLT and/or BQ, and easy availability of the product from hawkers outside school all contribute towards enhanced risk of SLT and/or BQ use in adolescents

The Effect of Foreign Bank Presence on Domestic Banks Performance: An Evidence from a Developing Economy

This study examines the effect of foreign bank presence on the behaviour of domestic banks by using the annual data of 37 commercial banks comprising of 7 foreign and 30 domestic banks for the time period of 2007 to 2011, to investigate the effect of foreign bank presence  five banking ratios, net interest margin, return on assets, overhead, cost to income and nonperforming loans using panel regression analysis employing bank specific fixed effect model. As a developing country case, the results suggest that the increase in foreign bank share effects the interest margins and profitability of domestic banks in a decreasing manner. It wouldn't be erroneous to express that foreign banks have a positive effect on the competitive environment of domestic banks increasing overall banking standard in Pakistan, the licensing policies should be further liberalized to let new entrants further improve the domestic financial intermediation system.&nbsp

Competition and market contestability of banks: evidence from emerging financial market

The study is an attempt to investigate the nature of competition and market contestability of 35 Pakistani banks for the period of 2007-2011 by employing Panzar and Rosse (PR-model). The test of competition overall sample (2007-2011) suggest that banks in Pakistan in state of monopolistic competition and market is in equilibrium. The sub sample (2007-2009) result of competition and equilibrium are similar as for sample period (2007-2011) suggesting that revenue produced during this period is state of monopolistic competition. Finally the results of sample period (2010-2011) suggest that banks in Pakistan are instate of perfect competition however, the market in not in long-run equilibrium. The results have interesting policy implications; it is suggested to encourage the foreign banks presence to improve the competitive condition of banking industry so that to ensure the exit and entrance of banks in the industry to increase the competition and produce the variety of product to improve banks performance and customer satisfaction.&nbsp

Exploring Linguistic Space Occupied by the Teachers and Students of an ESL Classroom in Gilgit-Baltistan, Pakistan: Comparisons Across Gender

Classroom talk plays a key role in language learning especially in English as second language (ESL) classrooms. Therefore, in this study the linguistic space occupied by the teacher and students in an ESL classroom has been investigated. A descriptive and exploratory approach was employed and videotaping was used for data collection during five consecutive classroom lessons. Results revealed that the teacher occupied most of the linguistics space (60%) as compared to the students (40%). The average word count of boys (56%) was comparatively higher than that of girls’ word count (44%). This study reports important insights into the patterns of teachers’ speech acts, students’ speech acts, silent and dominant students, length of students’ turns during classroom talk and comparisons across gender for both policy and practice

ADVANCEMENTS IN MARBURG VIRUS VACCINE DEVELOPMENT: UNRAVELLING RECENT FINDINGS. A NARRATIVE REVIEW.

Marburg Virus Disease (MVD) is a lethal single-stranded RNA virus transmitted by Egyptian rousette bats, causing 12 surges in Sub-Saharan Africa, including a recent outbreak in Tanzania in 2023. With a fatality rate of approximately 90%, no approved vaccines currently exist. Ongoing research explores potential candidates, such as a recombinant vesicular stomatitis virus (VSV)-based vaccine and MVA-BN-Filo, aiming to combat this deadly infection. The objective of this review is to comprehensively examine Marburg virus vaccines, exploring various candidates and their development stages, efficacy in non-human primates and human studies, and challenges faced in the development process. Various vaccines are under development, including Ad26, Ad5, viral vector, and DNA vaccines. Promising candidates like Ad26.Filo and ChAd3-MARV have emerged. Additionally, VLP-based, DNA plasmid and rVSV-based vaccines are discussed, highlighting their effectiveness and challenges in development, such as limited information, gene expression issues, and outbreak control measures. The implications for future research and clinical practice/policy development are significant. Marburg virus vaccine development shows promise in mitigating the threat posed by this deadly pathogen. Despite complex challenges, advancements in vaccine candidates offer hope. Continued research and development may lead to the successful prevention of major Marburg virus outbreaks. Ongoing clinical trials indicate potential breakthroughs in a short period, contributing to public health protection.
