Awareness of sustainability issues among science education and vocational education students at the Hashemite University in Jordan : an empirical investigation

The primary purpose of this study was to assess the level of students’ awareness about sustainability issues at the Hashemite University in Jordan. A 30-item instrument, adapted from Dunkerly-Kolb (1998), was used to collect data from a sample of 230 preservice science and vocational teachers during the academic year 2005-2006. Results indicated that preservice science and vocational teachers showed medium level of awareness about sustainability issues. Additionally, results indicated that participants appeared to be independent from their natural surroundings. The study suggested few practical solutions for faculty members and for the university administration to incorporate sustainability principles into university curricula.peer-reviewe

Attitudes toward Communication Skills among Students’-Teachers’ in Jordanian Public Universities

The present study was carried out to determine the positive and negative attitudes among 289 students of class teachers and childhood teachers\u27 disciplines using the communication skills attitude scale (CSAS) in Jordanian public universities. GPA, year level of students were recorded. Overall results of study revealed that the mean of positive attitude score was 4.03. The mean of negative attitude scale score was 3.63. There were no significant differences between class teachers and childhood teachers students in their positive and negative attitudes toward communication skills. Students with grade point averages 2 and more have positive attitudes toward communication skills than students with grade point average less than 2. Senior students have high positive and less negative attitudes toward communication skills than sophomore and junior students

Dark Web Analytics : A Comparative Study of Feature Selection and Prediction Algorithms

The value and size of information exchanged through dark-web pages are remarkable. Recently Many researches showed values and interests in using machine-learning methods to extract security-related useful knowledge from those dark-web pages. In this scope, our goals in this research focus on evaluating best prediction models while analyzing traffic level data coming from the dark web. Results and analysis showed that feature selection played an important role when trying to identify the best models. Sometimes the right combination of features would increase the model’s accuracy. For some feature set and classifier combinations, the Src Port and Dst Port both proved to be important features. When available, they were always selected over most other features. When absent, it resulted in many other features being selected to compensate for the information they provided. The Protocol feature was never selected as a feature, regardless of whether Src Port and Dst Port were available

Inference of Adaptive methods for Multi-Stage skew-t Simulated Data

Multilevel models can be used to account for clustering in data from multi-stage surveys. In some cases, the intra-cluster correlation may be close to zero, so that it may seem reasonable to ignore clustering and fit a single level model. This article proposes several adaptive strategies for allowing for clustering in regression analysis of multi-stage survey data. The approach is based on testing whether the cluster-level variance component is zero. If this hypothesis is retained, then variance estimates are calculated ignoring clustering; otherwise, clustering is reflected in variance estimation. A simple simulation study is used to evaluate the various procedures

Baseline characteristics and treatment pattern of type 2 diabetes patients in Jordan: analysis from the DISCOVER patient population

Introduction: Jordan has limited published data on T2DM and its treatment patterns. This analysis of the DISCOVER study, focusing on Jordan, is aimed at describing the characteristics of patients and treatment patterns according to the real-world setting in T2DM patients initiating a second-line antidiabetic treatment Methods: The DISCOVER study is an ongoing, multi-country, multicenter, observational, prospective, and longitudinal cohort study. The baseline data of patients’ characteristics, clinical and laboratory variables, micro- and macro-complications, and treatment choices were captured on a standardized case report form. Results: Two hundred and seventy-one patients were enrolled from 13 different clinical sites in Jordan. Sixty percent of the patients were male. The participants overall mean age was 53.8 ± 11.3 years with a mean BMI 30.8 ± 5.0 kg/m 2. The mean duration of T2DM was almost 6 years and the mean documented HbA1c and fasting plasma glucose were e 8.4% ± 1.6 and 180.9 ± 63.7 mg/dL, respectively, at the initiation of second-line antidiabetic treatment. Almost 25% of the participants were reported to be either current smokers or ex-smokers. More than 40% of patients had comorbidities such as hypertension or dyslipidemia. Diabetes related microvascular and macrovascular complications were documented in 10.3% and 12.5% of patients, respectively. Metformin (MET) alone was used as a first-line therapy in almost one-half of the patients and in combination with sulfonylurea (SU) in approximately one-third of the patients. The most commonly used second-line therapy was the combination of MET and dipeptidyl peptidase-4 inhibitors (DPP-4i) with 29.9% followed by the triple therapy of MET, SU, and DPP-4i with 28%. Conclusion: A substantial number of patients were young with uncontrolled diabetes and at high risk for micro- and macrovascular complications. Therefore, a comprehensive management with early treatment intensification and risk factors modifications are required to achieve target goals

Rehabilitating Iraqi Schools According to the Requirements of Social Sustainability

Recently, Social Sustainability has gained significant value as it was considered by the late studies as a principal dimension along with the environmental and economic sustainability. And because of, on the other hand, the significant social role of the school for forming the student’s personality, this research is an appeal for rehabilitating and promoting Iraqi Schools according the issue of social sustainability.As there is no evaluation for the Iraqi Schools, the research is dedicated to this problem, aiming to carry out the stated evaluation and define the design treatments needed for the rehabilitation process. To achieve this goal, a theoretical background for the concept of social sustainability, its criteria, the school and its social functions was introduced. From reviewing previous architectural practices and theoretical studies, different design treatments were extracted and structured within the level of the building itself and the outside landscape. The design treatments were, then, applied to rehabilitate a selected standard school model used by the Directorate of Education in Nineveh Governorate. Evaluating the proposed model, the conclusions demonstrated the possibility of rehabilitating the existing Iraqi Schools to hold most indicators of social sustainability

Genetic analysis : therapeutic drug monitoring of metformin and glimepiride on diabetic patients’ plasma including genetic polymorphism

Diabetes is a widespread disease that needs to be controlled. Therapeutic monitoring of drugs is very helpful in maintaining desirable doses. To study a correlation between the blood level of metformin (to a lesser extent, glimepiride) and genotyping (mainly the SULT1A1 genotype). Determine drug levels using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) tool. A validated LC-MS/MS method was developed to determine metformin and glimepiride levels in human plasma. DNA extraction was performed using Jena Bioscience’s Blood DNA preparation, in which a column kit was used to extract DNA for genetic polymorphism. The investigation was carried out using both medications in type 2 diabetes patients alongside the genetic polymorphism. One hundred and six patients were assessed. The prevalence of homozygosity for SULT1A1 and wild-type CYP2D6 * 4 were 72.6% and 73.6%, respectively. After adjustment for daily intake of metformin, three patients out of five with the highest levels of metformin had no homozygosity (SULT1A1 genotype). Statistically, variables that demonstrated an insignificant correlation with the level of metformin were body mass index (rs (87) = 0.32, P = 0.011) and age (rs (87) =0.26, P = 0.017). The homozygous (SULT1A1 genotype) correlation was moderate (rs (87) =0.21, P = 0.052). According to the findings, patients with the wt/wt CYP2D6 genotype had considerably greater levels of endoxifen than those with the v/v CYP2D6 genotype. The study’s results reported a probable correlation between the blood level of metformin (to a lesser extent, glimepiride) and genotyping (mainly the SULT1A1 genotype). Genotype-guided drug therapy may provide a novel contribution to maximize drug efficacy and/or minimize toxicity

The taper of cast post preparation measured using innovative image processing technique

<p>Abstract</p> <p>Background</p> <p>No documentation in the literature about taper of cast posts. This study was conducted to measure the degree of cast posts taper, and to evaluate its suitability based on the anatomy aspects of the common candidate teeth for post reconstruction.</p> <p>Methods</p> <p>Working casts for cast posts, prepared using Gates Glidden drills, were collected. Impressions of post spaces were made using polyvinyl siloxan putty/wash technique. Digital camera with a 10' high quality lens was used for capturing two digital images for each impression; one in the Facio-Lingual (FL) and the other in the Mesio-Distal (MD) directions. Automated image processing program was developed to measure the degree of canal taper. Data were analyzed using Statistical Package for Social Sciences software and One way Analysis of Variance.</p> <p>Results</p> <p>Eighty four dies for cast posts were collected: 16 for each maxillary anterior teeth subgroup, and 18 for each maxillary and mandibular premolar subgroup. Mean of total taper for all preparations was 10.7 degree. There were no statistical differences among the total taper of all groups (P = .256) or between the MD and FL taper for each subgroup. Mean FL taper for the maxillary first premolars was lower significantly (P = .003) than the maxillary FL taper of the second premolars. FL taper was higher than the MD taper in all teeth except the maxillary first premolars.</p> <p>Conclusions</p> <p>Taper produced did not reflect the differences among the anatomy of teeth. While this technique deemed satisfactory in the maxillary anterior teeth, the same could not be said for the maxillary first premolars. Careful attention to the root anatomy is mandatory.</p

Factors affecting medical students in formulating their specialty preferences in Jordan

<p>Abstract</p> <p>Background</p> <p>In recent years there has been a growing appreciation of the issues of career preference in medicine as it may affect student learning and academic performance. However, no such studies have been undertaken in medical schools in Jordan. Therefore, we carried out this study to investigate the career preferences of medical students at Jordan University of Science and Technology and determine factors that might influence their career decisions.</p> <p>Methods</p> <p>A cross-sectional questionnaire-based survey was carried out among second, fourth and sixth year medical students at the Jordan University of Science and Technology, Irbid, Jordan during the academic year 2006/2007. A total of 440 students answered the questionnaire which covered demographic characteristics, specialty preferences, and the factors that influenced these career preferences. Possible influences were selected on the basis of a literature review and discussions with groups of medical students and physicians. Students were asked to consider 14 specialty options and select the most preferred career preference.</p> <p>Results</p> <p>The most preferred specialty expressed by male students was surgery, followed by internal medicine and orthopaedics, while the specialty most preferred by female students was obstetrics and gynaecology, followed by pediatrics and surgery. Students showed little interest in orthopedics, ophthalmology, and dermatology. While 3.1% of females expressed interest in anesthesiology, no male students did. Other specialties were less attractive to most students.</p> <p>Intellectual content of the specialty and the individual's competencies were the most influential on their preference of specialty. Other influential factors were the "reputation of the specialty", "anticipated income", and "focus on urgent care".</p> <p>Conclusion</p> <p>Surgery, internal medicine, pediatrics, and obstetrics and gynaecology were the most preferred specialty preferences of medical students at Jordan University of Science and Technology.</p
