In particular, there is a dearth of published information on the increasing body mass index (BMI) of the most vulnerable Qatari sub-population – adolescents. This paper partially addresses this omission by documenting the BMI status of Qatari youth in 2008/2009; it also highlights the changes in BMI that occurred during the first decade of this century, when local risk factors were significantly increasing. Methods: Using a simple random sampling approach, adolescents were selected from a pool of Qatari children attending government schools in Qatar. This resulted in a comprehensive dataset of height and BMI for 705 boys and girls aged 12–17 years. Results: The overall prevalence of Qatari adolescents who were overweight/obese in 2008–2009 was 19.9%/26.7% (boys) and 23.2%/17.2% (girls). This represents a change in the prevalence of overweight/obesity of − 8.7%/+18.8 (boys) and +4.3%/+12.1% (girls) during the time between these studies. Conclusions: BMI increased substantially during the last decade, leading to a corresponding increase in the prevalence of adolescent obesity. These results demonstrate that regular monitoring of the BMI status of the Qatari adolescent population provides valuable predictors for adults.","PeriodicalId":121009,"journal":{"name":"QScience Connect","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130250657","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}

Service users can provide valuable insight into the nature and extent of this stigma. In Qatar, mental health stigma was not well studied previously. Methods: This study was part of mixed-methodology research. The research team conducted interviews in English or Arabic with outpatient mental health clinic attendees who participated in a quantitative survey in Qatar. For the qualitative part of the study, the interview guide was developed after the results were analyzed for the pilot phase of a national quantitative survey that engaged nurses, physicians, patients, and family members in discussions about mental health stigma. All interviews were recorded and transcribed for coding and thematic analysis. Arabic-language interviews were translated into English by a certified translation service. A framework was developed, which eventually included eight main themes and five sub-themes relating to perceptions of mental illness, stigma, and avoidance of stigma. Results: Seven people, all with previous mental health diagnoses, were included in the qualitative study. The participants described instances of stigma. Most of them did not disclose their mental health diagnoses to others. Stigma among the participants was often experienced by proxy. Stigma towards mental disorders in Qatar was believed to be caused by poor understanding of these diagnoses, media portrayals of persons with mental disorders, and perceptions arising from cultural/religious beliefs. Modifying lifestyles and concealing diagnosis helped the participants to avoid stigma within Qatar. Conclusions: All the participants believed that mental illness diagnoses carried social stigma. Most of them described efforts to avoid disclosing mental health diagnoses to others based on a fear of negative social consequences. These findings offer insight into the perceptions of service users in Qatar towards stigma and self-stigma.","PeriodicalId":121009,"journal":{"name":"QScience Connect","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126723100","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}

Alenazi, Bernard Barbour","doi":"10.5339/CONNECT.2019.5","DOIUrl":"https://doi.org/10.5339/CONNECT.2019.5","url":null,"abstract":"Dividend policy refers to the policy pertaining to the amount paid to shareholders of a company from the total financial budget as a return on their investment. This amount varies depending on the interest of shareholders, cash flow requirements of the company, and many other factors. Dividend policy can affect firm value due to its impact on the cash flow of the company. In this study, the first of its kind in Qatar, we investigated the effect of dividend policy on the firm value of Qatari banks in Qatar Stock Exchange. For this purpose, five banks (Qatar National Bank (QNB), Qatar Islamic Bank (QIB), Masraf Al-Rayan Bank (MARB), International Bank of Qatar (IBQ), and Commercial Bank of Qatar (CBQ)) were selected to find the significance of the correlation between dividend policy and firm value. The study was conducted in three distinct phases. The first phase included the quantitative analysis of the financial parameters of the five selected Qatari banks in which information about their recent five-year (2013–2017) dividend payments and firm values was obtained from their annual financial reports. Then, regression analysis was conducted in SPSS Statistics software. The second phase included the qualitative assessment of the results obtained from the first phase. To support this phase with expertise feedback, a director and a senior official were invited from two banks that showed a significant correlation in their financial parameters of dividend payments and firm values. They were asked about their policies to strengthen the firm value while keeping the interest of shareholders. The third phase included a detailed investigation of the results obtained from both the quantitative and qualitative studies, and the findings were compared with those reported previously in the literature. The research findings suggest that dividend policy has a very strong positive correlation for MARB, a strong positive correlation for QIB, a negative correlation for CBQ, and an irrelevant correlation for QNB and IBQ.","PeriodicalId":121009,"journal":{"name":"QScience Connect","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124610487","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 study adopted a mixed-methods research design that involved both experimental and comparison groups. Using the CAEQ (Chemistry Attitudes and Experiences Questionnaire) and the ASCI v2 (Attitude toward the Study of Chemistry Inventory), the findings of this study indicated that inquiry-based chemistry learning experience improves the students' intellectual accessibility and emotional satisfaction as well as develops their self-efficacy levels while pursuing intensive pre-medical courses in chemistry. The results of the qualitative data analyses using a course experience questionnaire indicated that the process-oriented guided inquiry learning (POGIL) experience helped the students succeed in rigorous pre-medical chemistry courses and gained some process skills required in the medical programme as listed by the AAMC (American Association of Medical Colleges).","PeriodicalId":121009,"journal":{"name":"QScience Connect","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133451381","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}
