Errors Analysis of Solving Linear Inequalities among the Preparatory Year Students at King Saud University.

The purpose of This study aims to investigate the errors classes occurred by the Preparatory year students at King Saud University, through analysis student responses to the items of the study test, and to identify the varieties of the common errors and ratios of common errors that occurred in solving inequalities. In the collection of the data, the researcher employed the open-ended questions test consisted of nine items distributive on three types of inequalities (linear, involve absolute value and fractional). In the data analysis, descriptive analysis method was used. The result sho­wed that some students had some misconceptions and misunderstanding in solving types of inequalities. The greatest common errors ratio was (20%) in solving linear inequality come from the class “Errors in basic algebraic operations and deletion. But the ratio (22%) were the greatest common errors ratio in solving fractional and involving absolute value inequalities come from the class errors in absent meaning of inequality.

Hypertension Prevalence, Awareness, Treatment and Control, and Associated Factors: Results from a National Survey, Jordan

The study examined prevalence, awareness, treatment and control of hypertension (HTN), and associated factors and to evaluate the trend in hypertension between 2009 (period 2) and 1994–1998 (period 1). A national sample of 4117 adults aged 25 years and older was selected. Prevalence rate of HTN (SBP ≥ 140 or DBP ≥ 90 or on antihypertensive therapy) was 32.3% and was higher than the 29.4% prevalence rate reported in period 1. Prevalence rate was significantly higher among males, older age groups, least educated, obese, and diabetics than their counterparts. The rate of awareness among hypertensives was 56.1% and was higher than the 38.8% rate reported form period 1 data. Awareness was positively associated with age, smoking, and diabetes for both men and women, and with level of education and body mass index for men. Rate of treatment for HTN among aware patients was 63.3% and was significantly higher than the 52.8% rate reported in period1. Control rate of HTN among treated hypertensives was 39.6%; significantly higher than the 27.9% control rate in period 1. Control of HTN was positively associated with age but only for women. In conclusion, HTN is still on the rise in Jordan, and levels of awareness and control are below the optimal levels

Stereotyping human-like virtual influencers in retailing: Does warmth prevail over competence?

Building upon the Stereotype Content Model (SCM), the current research provides insights into how virtual influencers (VIs) influence consumer responses. More specifically, it investigates the associations between the VI's anthropomorphism and stereotypical judgments of the VI's warmth and competence as well as the differential and mediating roles of these stereotypes in influencing consumers' willingness to follow the VI's recommendations and purchase intentions. The results support the idea that anthropomorphizing VIs has a direct bearing on stereotyping VIs along the competence and warmth dimensions of the SCM. Consistent with the “Primacy-of-Warmth Effect” hypothesis, the study's findings show that perceived warmth, compared to perceived competence, is positively more associated with consumers' willingness to follow the VI's recommendations. Furthermore, the findings reveal that perceived warmth mediates the association between the VI's anthropomorphism and consumers' willingness to follow the VI's recommendations. However, the findings lend partial support to the mediating role of competence. The willingness to follow the VI's recommendations, in turn, is positively associated with purchase intention. The paper wraps up with some implications for research and practice

Case Report: Unusual association of gubernacular canal, supernumerary tooth and odontoma with an impacted canine on cone beam computed tomography

This report describes a clinical case of asymptomatic compound odontoma in the anterior left side of the maxilla associated with an impacted canine and supernumerary tooth with a gubernacular canal of a 47- year-old female with no relevant medical history. Cone-beam computed tomography (CBCT) was performed for precise three-dimensional localization of each structure and assessment of their spatial relationship with the associated structures before surgery. The treatment protocol involved surgical enucleation of the odontoma and open extraction of both impacted and supernumerary teeth. Patient had uneventful healing and proceeded with the prosthodontic treatment plan. An experienced clinician can accurately diagnose a compound odontoma, as it has distinctive clinical and radiographic features. Thus, early detection and management of odontomas can help correction of any dental irregularity and avoid further complications.Scopu

Case Report: An association of the gubernacular canal, supernumerary tooth and odontoma with an impacted canine on cone-beam computed tomography [version 2; peer review: 3 approved]

This report describes a clinical case of asymptomatic compound odontoma in the anterior left side of the maxilla associated with an impacted canine and supernumerary tooth with a gubernacular canal of a 47- year-old female with no relevant medical history. Cone-beam computed tomography (CBCT) was performed for precise threedimensional localization of each structure and assessment of their spatial relationship with the associated structures before surgery. The treatment protocol involved surgical enucleation of the odontoma and open extraction of both impacted and supernumerary teeth. The patient had uneventful healing and proceeded with the prosthodontic treatment plan. The dentist should be aware of the probability of a close relationship between the development of odontoma and presence of the gubernacular tract, which could be used as a future radiographic diagnostic criterion of an odontoma. Also, we recommend that more studies be performed in this field to deeply analyze the imaging characteristics of GT and its spatial association with various pathological lesions in the future.Grant information: This research was funded by the Deanship of Scientific Research at Princess Nourah bint Abdulrahman University through the Fast-track Research Funding Program.Scopu
