Attitude of Saudi Female Math Teachers toward Integrating E-learning in Teaching Math at High Schools in Saudi Arabia

Attitude of Saudi Female Math Teachers toward Integrating E-learning in Teaching Math at High Schools in Saudi Arabia Aishah M. Albalawi Leaders in government and education have launched an extensive program to reform general education in Saudi Arabia. This initiative was designed to achieve many goals with a major emphasis being the enhancement of the Saudi curriculum to take advantage of the use of technology to improve education. A goal of this project was for e-learning to be a part of public education in an attempt to improve student learning and to make education accessible to all citizens. This study was designed to examine high school female math teachers’ attitudes toward the use of e-learning in teaching mathematics in selected high schools in Tabuk, Saudi Arabia. It also sought to determine the extent to which e-learning had been adopted in high schools. The study also examined the results to determine if there were any statistically significant differences in female math teachers’ attitudes toward e-learning based on the variables of academic degree, years of experience, computer course training, and computer lab availability. A 5-point Likert scale questionnaire was used to collect data on teacher attitudes toward the use of e-learning in education. Descriptive statistics were used to analyze much of the data generated from the questionnaire. Means, standard deviations, ranges, frequencies, percentages, and diagrams were used to compile and analyze the data. A t-test was used to test for statistically significant differences in teachers’ attitudes for the variables of academic degree, years of experience, computer course training, and computer lab availability. The analysis of the responses to the questionnaire revealed that the female high school math teachers’ attitudes toward the use of e-learning were highly positive. The mean responses to the questionnaire items revealed that the teachers believed that e-learning made teaching more effective, more interesting, and enhanced the quality of teaching. There was general agreement that e-learning helped them meet the individual needs of the learners. The results of the study revealed that there were no statistically significant differences in teachers’ attitudes toward elearning when examined for the variables of academic degree, years of teaching experience, computer course training, and computer lab availability. Recommendations were made for professional development, in-service training, technology integration, and logistics and infrastructure improvement.
The Sweet Spot between Inverted Indices and Metric-Space Indexing for Top-K-List Similarity Search ⇤

We consider the problem of processing similarity queries over a set of top-k rankings where the query ranking and the similarity threshold are provided at query time. Spear- man's Footrule distance is used to compute the similarity between rankings, considering how well rankings agree on the positions (ranks) of ranked items (i.e., the L1 distance). This setup allows the application of metric index structures such as M- or BK-trees and, alternatively, enables the use of traditional inverted indices for retrieving rankings that overlap (in items) with the query. Although both techniques are reasonable, they come with individual drawbacks for our specific problem. In this paper, we propose a hybrid index- ing strategy, which blends inverted indices and metric space indexing, resulting in a structure that resembles both in- dexing methods with tunable emphasis on one or the other. To find the sweet spot, we propose an assumption-lean but highly accurate (empirically validated) cost model through theoretical analysis. We further present optimizations to the inverted index component, for early termination and mini- mizing bookkeeping. The performance of the proposed al- gorithms, hybrid variants, and competitors is studied in a comprehensive evaluation using real-world benchmark data consisting of Web-search-result rankings and entity rankings based on Wikipedia.
Inter-Organizational Systems and Supply Chain Management - An Information Processing Perspective

Supply chain management has become an excellent strategy to effectively link all the trading partners and ensure cost effective and timely movement of materials from the raw material supplier to the final end-consumer.Inter-organizational systems provide the technology infrastructure to facilitate the flow of information along the chain and thereby ensuring the smooth flow of goods. The two areas have been developing independently without realizing the synergies in integrating the research from the two fields. This paper attempts to provide an integrated perspective of supply chain management and interorganizational systems highlighting the potential benefits, management issues, and guidelines for implementation.
Enhancing symbolic execution with veritesting

1. INTRODUCTION Symbolic execution is a popular automatic approach for testing software and finding bugs. Over the past decade, numerous symbolic execution tools have appeared—both in academia and industry—demonstrating the effectiveness of the technique in finding crashing inputs, generating test cases with high coverage, and exposing software vulnerabili-ties.
Asthma insights and reality in Korea

Background : Asthma management guidelines provide recommendations for the optimal control and goals of management. This survey was performed as a part of Asthma Insights and Reality in Asia-Pacific Region (AIRIAP) study to assess the current levels of asthma control reported by patients, which partly reflect the extent to which guideline recommendations are implemented. Methods : From September to December 2000, current asthma patients were identified by random door-to-door visits by screening 13,988 households in Seoul, Korea. Designated responders were interviewed on asthma control, symptom severity, activity limitations and healthcare utilization. Results : Current asthmatics were identified in 1,024 households, and 401 patients completed the survey. Daytime asthma symptoms were reported by 52%, and 26% reported sleep disturbance caused by asthma at least once a week in the past 4 weeks. In the past 12 months, 14% had been hospitalized, 6% attended emergency departments, and 30% made unscheduled emergency visits. Patient's perception of asthma control was different from their actual asthma control. Current use of an inhaled corticosteroid was reported by only 0.2% of responders. Absence from school and work in the past year was reported by 14% of adults and 7% of children. Conclusions : The current level of asthma control in Korea falls markedly short of the goals specified in international guidelines for asthma management. Management according to the guideline and patient education is important for the optimal control of asthma. Development of practically easy asthma management guideline for primary physician may be also important for its implementation.
P o S ( I C R C 2 0 1 5 ) 1 1 3 3 A Precision Optical Calibration Module for IceCube-Gen 2

A next generation of IceCube is under design including the Precision IceCube Next Generation Upgrade (PINGU) for the neutrino mass ordering and an extended array for astrophysical neutrino sources. A new level of precision is needed in order to guarantee improved performance with respect to IceCube. An improved calibration system will enable a better understanding of the ice and will therefore significantly reduce systematic effects. We present a new instrument called the Precision Optical Calibration Module (POCAM). By keeping the outer topology identical to that of the IceCube Digital Optical Module (DOM), cost-effective construction and deployment is ensured. The design of the POCAM is based on the principle of an inverted integrating sphere. An appropriately placed LED in combination with a diffusing layer on the inside of the sphere results in a nearly homogeneous light emission from the apertures in the spherical housing. The output of the LED is monitored in-situ to high precision, ensuring control over the output from the apertures. The POCAM has been simulated and tested in the framework of Geant4. A prototype POCAM is under construction. We report on the status of the POCAM R&D.
Experimental model identification of liquid-circular angular accelerometer using subspace method

In this paper, the model of a novel liquid-circular angular accelerometer is studied. Due to the absence of theoretical model of liquid-circular angular accelerometer, a subspace identification method(SIM) based on Akaike Information Criterion(AIC) is chosen for model identification of angular accelerometer. The proposed identification method is tested on a liquid-circular angular accelerometer prototype. The experimental results indicate that SIM could obtain a more accurate model than least square method, with a degree of fitting above 90%. In addition, SIM possesses good repeatability and stability. The experimental model identified by SIM in this paper can be applied in engineering practice.
Studies of peripheral large and small nerve fibre disease with emphasis on diabetic polyneuropathy

Objective: To collect a reference material of the medial plantar nerve action potential, to test intra/interobserver reliability in healthy controls and to apply the test to a group of patients with diabetes mellitus. Methods: 98 healthy controls and 50 patients with diabetes mellitus were included. The medial plantar nerve was stimulated orthodromically and recorded with a surface electrode. In the patient group, NCS of motor and sensory nerves and quantitative sensory testing were also performed. Results: Responses of the medial plantar nerve were obtained from all controls except from one aged 72. Amplitude decreased with age (r = 0.68, p < 0.0001). Intra/interobserver reliability was acceptable. 52% of the patients had abnormal overall NCS classification. Forty-eight percent had delayed tibial F-response latency. The medial plantar NCS were abnormal in 59% of the cases (47% abnormal NAP amplitude and 39% reduced CV), 59% of those with abnormal NCS had symptoms of sensory polyneuropathy. Only 24% had abnormal sural amplitude. Cold perception threshold was abnormal in more patients (30%) than warmth perception threshold (14%). Conclusions: Responses were easily obtained in controls under 70 years. In diabetics the amplitudes of the medial plantar nerve were abnormal more often than in the sural nerve. Significance: The medial plantar nerve response is reliable in patients under 70 years, and intra/interobserver reliability is acceptable. 2007 International Federation of Clinical Neurophysiology.

TREATMENT OF TOXICOSIS WITH THE AID OF A CONTINUOUS INTRAVENOUS DRIP OF DEXTROSE SOLUTION

INTRODUCTION By Dr. Schick The disease commonly referred to as alimentary intoxication, toxicosis or cholera infantum has become relatively rare during the last decade, apparently because of the greater knowledge of the feeding of infants and the better education of the mothers. Especially the strict supervision of the milk supply deserves a great deal of credit for the decrease of the disease. The condition, however, presents itself often enough, mostly during the summer and until the middle or end of October, and the mortality is sufficiently high to be a troublesome problem. I became interested in the problem after I freed myself from the fear of sugar in feeding normal children. At this time the majority of pediatricians were still under the influence of the teachings of Finkelstein and his pupils, who saw at first in the salts and later in the carbohydrates, especially in the sugar, the main cause
Speech Based Depression Detection using Convolution Neural Networks

Depression has become a serious mental disorder nowadays affecting people of almost all age groups. Loss of interest in daily activities, constant feeling of being isolated, hopelessness etc. causing significant impairment in life. This illness will affect the physical and mental health of the individual affecting his/her emotional stability. Emotions are a way of expression of one’s state of mind in the form of thoughts, feelings or behavioural responses. For a depressed individual, the emotions are often negative in nature. Diagnosis of depression is a complex task as the disease may be unidentified by the patient itself. Sometimes the patient may be reluctant to consult a doctor. The long term ignorance of the illness may worsen the mental health of the one suffering from it. Thus the early diagnosis of depression is of great significance. With the emergence of neural networks and pattern recognition, many researchers have put effort in detecting depression by analysing non-verbal cues, such as facial expressions, gesture, body language and tone of voice. Recent studies have shown that the speech emotion analysis can effectively be used in distinguishing emotional features and a depressed speech varies from that of a normal speech to a great extent. The depressed patient normally speaks in a low voice, slowly, sometimes stuttering, whispering, trying several times before they speak up or become mute in the middle of a sentence. This paper proposes a CNN architecture for learning the audio features in the speech for detecting depression, identifying the emotions and to infer the emotional severity of the individual. This paper also reviews some of the existing research methods in the field of depression analysis.
Expressiveness and complexity of XML publishing transducers

A number of languages have been developed for specifying XML publishing, that is, transformations of relational data into XML trees. These languages generally describe the behaviors of a middleware controller that builds an output tree iteratively, issuing queries to a relational source and expanding the tree with the query results at each step. To study the complexity and expressive power of XML publishing languages, this article proposes a notion of publishing transducers, which generate XML trees from relational data. We study a variety of publishing transducers based on what relational queries a transducer can issue, what temporary stores a transducer can use during tree generation, and whether or not some tree nodes are allowed to be virtual, that is, excluded from the output tree. We first show how existing XML publishing languages can be characterized by such transducers, and thus provide a synergy between theory and practice. We then study the membership, emptiness, and equivalence problems for various classes of transducers. We establish lower and upper bounds, all matching, ranging from PTIME to undecidable. Finally, we investigate the expressive power of these transducers and existing languages. We show that when treated as relational query languages, different classes of transducers capture either complexity classes (e.g., PSPACE) or fragments of datalog (e.g., linear datalog). For tree generation, we establish connections between publishing transducers and logical transductions, among other things.
PCR Detection of Herpes Simplex Virus in Human Placenta and Aborted Materials in Patients with Spontaneous Abortion

Objective: Herpes simplex virus (HSV) infection during pregnancy may lead to fetal loss. The aim of this study was to explore the infection rate of HSV type 1 and 2 infection associated with spontaneous abortion in a pilot case-control study in two cities of Iran in 2010. Patients and Methods: Placenta and curettage samples from 35 healthy full term neonates and 35 cases of spontaneous abortion with related questionnaires were collected. Sample DNA was extracted using Qiagen extraction kit, and then PCR was applied for detection of both types of viruses. In parallel, results were checked using SinaClon detection kit. Results: In this study 2.8% (1/35) of samples taken from aborted materials were found to be HSV positive (p=0.497). Differences were detected between case and control groups regarding vaginal infection (p =0.001) and having previous spontaneous abortion (p =0.018). Conclusion: Our findings revealed that HSV can be an abortion-related factor in pregnancy
A " H URST COEFFICIENT " ESTIMATION WITH WAVELETS : A PPLICATION TO THE ENERGY SECTOR

The energy financial products prices could be affected by herding behavior, speculation and also by supply and demand of the physical assets. This situation is likely to generate economic cycles and a rejection of the efficiency market hypothesis. Then, the aim of this paper is to check the presence of memory in the energy Futures prices. We calculate a useful parameter the "Hurst coefficient", by using a specific tool coming from the signal theory, the wavelet decomposition. Our findings with rolling regressions are that most markets, since the beginning of 90ties, are in a process of maturity and show less and less memory of any type (short or long). Electricity displays long memory, whereas the crude oil markets present some short memory.
Interactive comment on “ Emissions of air pollutants and greenhouse gases over Asian regions during 2000 – 2008 : Regional Emission inventory in ASia ( REAS ) version 2 ” by J .

Sect. 2.2. 5 Seasonal variation and grid allocation: The statistics activity data set used in this study is based on the country and sub-region (e.g. province for China) levels, with geographical areas being much higher than 0.25N × 0.25E degree. The authors applied higher resolution population data to allocate the emissions from the area sources to such grid cells. This kind of method is reasonable in the emission estimate of some activities, but it may not work for other emission sources, e.g. from large industrial plants. In addition to power plants, other large industrial plans, such as steel and cement plants, should be considered as point sources. The authors have a discussion of this issue in the paper, but unfortunately they prefer to dealing with it in the next version of the inventory. To find a location of a large steel and iron manufacturing enterprise by its name may not be too difficult. It seems that their inventory is not entirely ready for 0.25N × 0.25E grid cells.
STUDIES ON EVALUATION OF STEM CELL LINEAGE IN CANINE MAMMARY TUMOR

The present study was envisaged to ascertain lineage/expression pattern of molecular markers of cancer stem cell in the early and late lesions of canine mammary tumor. The study included archived samples of 50 cases of canine mammary tumor of which 31 cases showing early and late lesions were screened and evaluated for stem cell markers like ALDH1, BRCA1, c-Myc, BCL2, S100A7, Rb, and CD24 by immunohistochemistry. Among 31 cases, 13 cases were studied for c-Myc gene amplification by Chromogenic in situ Hybridization (CISH) method. A TaqMan Real Time PCR was also employed to observe the gene amplification in 19 of 31 cases. Proliferative potential of cancer cells was assessed by Nuclear Feulgen Reaction. Immunoreaction was both cytoplasmic and nuclear for c-Myc, BRCA1, S100A7, only cytoplasmic for ALDH1 and BCL2, while it was nuclear in case of Rb. Immunoreactivity of ALDH1, BRCA1, c-Myc, BCL2 and S100A7 was noticed in the 26, 26, 27, 23, 21 cases, respectively. The c-Myc immunoreaction was seen to be more nuclear in early lesions and cytoplasmic in late lesions. There was loss of expression of BRCA1, BCL2 and Rb in more advanced lesions. Out of 31 cases, the Rb immunoreactivity was well preserved in 3 cases while, loss of immunoreactivity was 90% and 70-80% in 11 and 7 cases, respectively. None of these cases showed immunoreactivity for CD24 proteins. CISH revealed c-Myc amplification in 4 cases out of 13 while, 6 out of 19 cases showed gene amplification by PCR. In conclusion, the cells expressing BRCA1, Rb and BCL2 markers represent the early cancer stem cells population whereas, cells expressing ALDH1, c-Myc and S100A7 markers represent both the early as well as late cancer stem cells. The loss of BRCA1 results in increased expression of c-Myc and ALDH1.
Assessing Productivity and Performance of Seaports: The Importance for Gateways

The advent of containerization has increased transshipment possibilities through some ports, while reducing the competitive advantages of others. The supply chain management concept implies that successful ports must add value to the movement of freight, such as by decreasing transit time or by providing valueadded services. In light of these environmental developments, potential port strategies are analyzed using Porter’s (1980) three generic strategies and through the lens of the resource-based view of competitive advantage. Different resource characteristics are identified with distinct strategies. The major implication for port management is the need to closely assess a port’s operating position in order to properly arrive at a competitive strategy.
The updated version of the scientific article ‘ Numerical modeling of the 2013 meteorite entry in Chebarkul Lake , Russia ’ , by

The results of the numerical simulation of possible hydrodynamic perturbations in Lake Chebarkul (Russia) as a consequence of the meteorite fall of 2013 (Feb. 15) are presented. The numerical modeling is based on the Navier-Stokes equations for a two-phase fluid. The results of the simulation of a meteorite entering the water at an angle of 20 degrees are 10 given. Numerical experiments are carried out both when the lake is covered with ice and when it isn’t. The estimation of size of the destructed ice cover is made. It is shown that the size of the observed ice-hole at the place of the meteorite fall is in good agreement with the theoretical predictions, as well as with other estimates. The heights of tsunami waves generated by a small meteorite entering the lake are small enough (a few centimeters) according to the estimations. However, the danger of a tsunami of meteorite or asteroid origin should not be underestimated. 15
DOES THE LOCATION OF MANUFACTURING DETERMINE SERVICE SECTORS’ LOCATION CHOICES? EVIDENCE FROM PORTUGAL

Considering the case of Portugal over the period 1995-2000, this paper analyses whether the location of market services is explained by the geographical proximity of the industrial sectors that use these services as intermediate inputs. A rather detailed level of regional disaggregation is used, namely the county level (275 counties). This influence is confirmed by the results of some location indices and by the regressions made for each sector. An alternative spatial unit is also used, consisting of the county itself combined with those with which it shares boundaries, showing the relevance of the level of regional disaggregation for the results obtained.
