Student‐centered integrated anatomy resource sessions at Alfaisal University

Alfaisal University is a new medical school in Riyadh, Kingdom of Saudi Arabia that matriculates eligible students directly from high school and requires them to participate in a hybrid problem‐based learning (PBL) curriculum. PBL is a well‐established student‐centered approach, and the authors have sought to examine if a student‐centered, integrated approach to learn human structures leads to positive perceptions of learning outcomes. Ten students were divided into four groups to rotate through wet and dry laboratory stations (integrated resource sessions, IRSs) that engaged them in imaging techniques, embryology, histology, gross anatomy (dissections and prosections), surface anatomy, and self‐directed learning questions. All IRSs were primarily directed by students. During two second‐semester organ system blocks, forty students responded to a structured questionnaire designed to poll students' perceptions of changes in their knowledge, skills, and attitudes as a result of IRS. The majority (60%) of students felt that the student‐centered approach to learning enhanced their medical knowledge. Most students also felt that the IRS approach was advantageous for formulating clear learning objectives (55%) and in preparing for examinations (65%). Despite their positive feelings toward IRS, students did not view this learning approach as an adequate replacement for the knowledge gained from lectures and textbooks. Students' performance on objective structured practical examinations improved significantly for the two curricular blocks that included IRS compared with earlier non‐IRS blocks. A student‐centered approach to teach human structure in a hybrid PBL curriculum may enhance understanding of the basic sciences in first‐year medical students.

Data and infrastructure security auditing in cloud computing environments

For many companies the remaining barriers to adopting cloud computing services are related to security. One of these significant security issues is the lack of auditability for various aspects of security in the cloud computing environment. In this paper we look at the issue of cloud computing security auditing from three perspectives: user auditing requirements, technical approaches for (data) security auditing and current cloud service provider capabilities for meeting audit requirements. We also divide specific auditing issues into two categories: infrastructure security auditing and data security auditing. We find ultimately that despite a number of techniques available to address user auditing concerns in the data auditing area, cloud providers have thus far only focused on infrastructure security auditing concerns.     

Exact solutions for the generalized KdV equation by using Backlund transformations

In this paper, the Backlund transformations for the generalized KdV equation are constructed through Ablowitz–Kaup–Newell–Segur (AKNS) system in using Ricatti's form of the inverse method. The derived Backlund transformations are used to generate new classes of exact solutions. The technique developed here is based on the construction of wave functions which are the solutions of the associated AKNS. From known simple solutions we shall construct other solitons and wave solutions as well.     

Developmental patterns of children's shyness: Relations with physiological,emotional, and regulatory responses to being treated unfairly

The dysregulation of social fear has been widely studied in children's shyness, but we know little about how shy children regulate during unfair treatment. We first characterized developmental patterns of children's shyness (N = 304, n_girls = 153; 74% White, 26% Other) across 2 (M_age = 2.07), 3 (M_age = 3.08), 4 (M_age = 4.08), and 6 (M_age = 6.58) years of age. Data collection occurred from 2007 to 2014. At age 6, the high stable group had higher cardiac vagal withdrawal and lower expressed sadness and approach-related regulatory strategy than the low stable group when being treated unfairly. Although shy children may be more physiologically impacted by being treated unfairly, they may mask their sadness to signal appeasement.     

An Application of Multiple Intelligences in a Lebanese Kindergarten

This study is an application of a Multiple Intelligences-based approach to assessment and educational practice in early childhood years, the Spectrum Project, in a Lebanese kindergarten. A control group design was used. The Spectrum activities were manipulated for the whole academic year by 150 kindergarten students (75 girls, 75 boys), enrolled in one branch of a private school, while the other branch of the same school worked with the regular curriculum. The purpose of the study was to determine if, through assessment of those activities, a profile of children's abilities, strengths, and weaknesses could be identified. Means and standard deviations for every activity were reported. A second purpose was to investigate the relationship between the different domains or intelligences. Pearson product-moment coefficients were computed. Finally, the difference in the end-of-year achievement between the experimental and the control group was investigated. The data are discussed in terms of cross-cultural interpretations. Implications and recommendations for future research are presented.     

Antibacterial and antifungal activities of different parts of Tribulus terrestris L. growing in Iraq

Antimicrobial activity of organic and aqueous extracts from fruits, leaves and roots of Tribulus terrestris L., an Iraqi medicinal plant used as urinary anti-infective in folk medicine, was examined against 11 species of pathogenic and non-pathogenic microorganisms: Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Corynebacterium diphtheriae, Escherichia coli,Proteus vulgaris, Serratia marcescens, Salmonella typhimurium, Klebsiella pneumoniae, Pseudomonas aeruginosa and Candida albicans using microdilution method in 96 multiwell microtiter plates. All the extracts from the different parts of the plant showed antimicrobial activity against most tested microorganisms. The most active extract against both Gram-negative and Gram-positive bacteria was ethanol extract from the fruits with a minimal inhibitory concentration (MIC) value of 0.15 mg/ml against B. subtilis,B. cereus, P. vulgaris and C. diphtheriae. In addition, the same extract from the same plant part demonstrated the strongest antifungal activity against C. albicans with an MIC value of 0.15 mg/ml.     

Validity of acute phase proteins and trace metals as adjuncts in viral hepatitis A and B

The level of seven acute phase proteins was estimated together with copper and zinc in two groups of 15 children each suffering from hepatitis A (HAV) or Hepatitis B (HBV). The mean concentration of α-1 antitrypsin, α-2 macroglobulin, ceruloplasmin, C3 and copper was increased uniformly in both the types of viral hepatitis. α-1 acid glycoprotein, haptoglobin and zinc levels were decreased in both the infections. A significant decrease in albumin level was observed in HAV while the decrease was not significant in HBV. All the paramenters were repeated after one month on the day of discharge following the disappearance of clinical signs and symptoms wherein the haptoglobin level returned to normal in HAV. No change was observed in the level of other acute phase proteins. The level of the trace elements returned to normal. The observed increase in the levels of acute phase proteins at the onset does not seem to have any significant relation to the subsequent course of the disease. However, the level of acute phase proteins and other biochemical parameters may indicate a delayed biochemical recovery phase in conjunction with the underlying hepatic pathological changes in the course of viral hepatitis in spite of clinical recovery.     

Validating the Watson Glaser Critical Thinking Appraisal

This study validated the Watson Glaser Critical Thinking Appraisal (WGCTA) on a sample of 273 private university students in Lebanon. For that purpose, evidence for construct validation was investigated through identifying the test’s factor structure and subscale total correlations, in addition to differences in scores by gender, different levels, and streams using a series of ANOVA tests. Evidence for the test’s reliability and concurrent validity was also collected. Moreover, students in five courses that emphasize critical thinking were pre–post tested using the WGCTA. Exploratory factor analysis revealed a unidimensional factor while results showed no significant differences in scores on the WGCTA between males and females or between students at different levels except for graduate students in the Business stream. Furthermore, results revealed significant differences for the senior students between different streams. Finally, results showed no statistically significant changes in the mean scores of students who were pre- and post-tested except for nursing students. The test’s significant correlations with various criterion measures provided evidence of its convergent and divergent validities. The results were discussed in terms of the nature of the construct itself, and the effects of training and effective instructional strategies on growth of critical thinking. Recommendations for future research were proposed.     

Student control ideology and the science classroom environment in urban secondary schools of sudan

An examination was made concerning the relationships between Sudanese secondary science teachers' pupil control ideology and their students' perceptions/observations of the psychosocial environment of their science classrooms. One hundred secondary science teachers were classified as possessing humanistic (N = 20) or custodial (N = 20) control ideologies. A class (N = 40) of students was randomly selected for every teacher in both groups. The findings revealed that no significant relationships existed between the control ideologies of the teachers and their students' perceptions/observations of the classroom environment. Custodialism in control ideology was significantly related to the classroom environment psychosocial aspect of low “support.” Discussion and implications of the findings have been approached from both Sudanese and American perspectives.
