Bar Model as Intervention in Solving Word Problem Involving Percentage

This experimental case-study examined the performance of convenient sampling of fourty-five Year 9 students in solving word problems involving percentage from two classes in one government secondary school in Brunei Darussalam, using Bar Model as a solving strategy. Data was gathered quantitatively through written tests in the form of six word problem items as pre-test and post-test.Â The mean score of the pre-test was 0.93 indicating that the performance of the participating Year 9 students in solving word problems involving percentage was low prior to intervention. Intervention lessons produced a gain in the post-test mean to 2.87.Â Although the mean of post-test marks is still lower than the passing mark of the test, paired-sample t-test provided evidence of significance, thus proving that Bar Model Method had positive effect to the performance of word problem involving percentage. Evidence also indicated an increase in the studentsâ€™ overall marksÂ from pre-test to post-test, with almost all except two students failed the pre-test to twenty-six students achieving marks above passing mark of 3 in post-test.Â Item-by-item analysis showed increase in correct responses in every item in post-test, even those with no attempts in pre-test.Â These provided further evidence that there is overall improvement in studentsâ€™ performance in word problems related to percentage after the use of Bar Model as intervention.
Temporal mammographic registration for evaluation of architecture changes in cancer risk assessment

While breast cancer screening recommendations vary by agency, all agencies recommend mammographic screening with some frequency over some portion of a woman’s lifetime. Temporal evaluation of these images may inform personalized risk of breast cancer. However, due to the highly deformable nature of breast tissue, the positioning of breast tissue may vary widely between exams. Therefore, registration of physical regions in the breast over time points is a critical first step in computerized analysis of changes in breast parenchyma over time. While a postregistration image is altered and therefore not appropriate for radiomic texture analysis, the registration process produces a mapping of points which may aid in aligning similar image regions across multiple time points. In this study, a total of 633 mammograms from 87 patients were retrospectively collected. These images were sorted into 1144 temporal pairs, where each combination of images of a given women of a given laterality was used to form a temporal pair. B-splines registration and multi-resolution registration were performed on each mammogram pair. While the B-splines took an average of 552.8 CPU seconds per registration, multi-resolution registration took only an average of 346.2 CPU seconds per registration. Multi-resolution registration had a 15% lower mean square error, which was significantly different than that of B-splines (p&lt;0.001). While previous work aimed to allow radiologists to visually evaluate the registered images, this study identifies corresponding points on images for use in assessing interval change for risk assessment and early detection of cancer through deep learning and radiomics.

The Map as a Search Box: Using Linked Data to Create a Geographic Discovery System

This article describes a bibliographic mapping project recently undertaken at the Library of the Institute for the Study of the Ancient World (ISAW). The MARC Advisory Committeerecently approved an update to MARC that enables the use of dereferenceable Uniform Resource Identifiers (URIs) in MARC subfield $0. The ISAW Library has taken advantage of MARC’s new openness to URIs, using identifiers from the linked data gazetteer Pleiades in MARC records and using this metadata to create maps representing our library’s holdings. By populating our MARC records with URIs from Pleiades, an online, linked open data (LOD) gazetteer of the ancient world, we are able to create maps of the geographic metadata in our library’s catalog. This article describes the background, procedures, and potential future directions for this collection-mapping project.

Toward Efficient Spammers Gathering in Twitter Social Networks

This paper introduces a novel system, named pseudo-honeypot, for efficient spammers gathering. Different from the manual setup in the honeypot, the pseudo-honeypot takes advantage of Twitter users' diversity and selects accounts with the attributes of having the higher potentials of attracting spammers, as the parasitic bodies. By harnessing a set of normal accounts possessing these attributes and monitoring their streaming posts and behavioral patterns, the pseudo-honeypot can gather the tweets that are far more likely of including spammer activities, while removing the risks of being recognized by smart spammers. It substantially advances the honeypot-based solutions in attribute availability, deployment flexibility, network scalability, and system portability. We present the system design and implementation of pseudo-honeypot (including node selection, monitoring, feature extraction, and learning-based classification) in Twitter networks. Through experiments, we demonstrate its effectiveness in term of spammer gathering.
Adaptive Control of a Four-Dimensional Hyperchaotic System

This paper concerns the application of adaptive control method in a four-dimensional hyperchaoticsystem. Firstly, we carry out a systematic dynamic analysis including the properties of equilibriumpoint, stability, dissipation, Lyapunov exponent spectrum, and bifurcation. Both the existenceof two positive Lyapunov exponents and the Lyapunov dimension value show the hyperchaotic property of the system. Based on Lyapunov stability theorem, we then construct an adaptive controller and the adaptive law to suppress hyperchaos to the origin, which is an unstable equilibrium point under a certain parameter set. The effectiveness of the adaptive control is veried by theoretical analysis and numerical simulation. We nally brie y demonstrate the control eciency of self-linear feedback control and misaligned feedback control. For the fourdimensional hyperchaotic system, the adaptive control outperforms them from the view of control speed.
Drugs and Substance Abuse among the Secondary School Students in Korogocho: Implications for Behaviour and Performance

&lt;p&gt;Globally, Drugs and substance abuse continues to be a challenge, especially among the youth in school and out of school. It impacts negatively on the academic, social psychological and physical development among the abusers. This paper examines the effects of drugs and substance abuse on social conduct and academic performance among the students as well as the mitigating measures. It is based on a study carried out at Korogocho slums. A total of 102 students and 15 key informants were sampled. Questionnaire and interview guide were used to collect data. The study revealed that marijuana, miraa, alcohol and cigarettes are the most abused drugs by secondary school students and had eroded the core values hence affecting their social skills development and academic performance. The study concluded that slum life, peer pressure, congestion as well as poverty are the recipe to drug and substance abuse among students. The study recommends increased public awareness campaigns on dangers posed by drug and substance abuse involving media, civic education and all the stakeholders; and proper policy formulation and implementation.&lt;/p&gt;
Goal Identification Control Using an Information Entropy-Based Goal Uncertainty Metric

Recent research has found situations where the identification of agent goals could be purposefully controlled, either by changing the underlying environment to make it easier, or exploiting it during agent planning to delay the opponent’s goal recognition. The paper tries to answer the following questions: what kinds of actions contain less information and more uncertainty about the agent’s real goal, and how to describe this uncertainty; what is the best way to control the process of goal identification. Our contribution is the introduction of a new measure we call relative goal uncertainty (rgu) with which we assess the goal-related information that each action contains. The rgu is a relative value associated with each action and represents the goal uncertainty quantified by information entropy after the action is taken compared to other executable ones in each state. After that, we show how goal vagueness could be controlled either for one side or for both confronting sides, and formulate this goal identification control problem as a mixed-integer programming problem. Empirical evaluation shows the effectiveness of the proposed solution in controlling goal identification process.

SHEFFIELD LECTURE - YALE UNIVERSITY JANUARY 11, 2000 INTERNET LEARNING: IS IT REAL AND WHAT DOES IT MEAN FOR UNIVERSITIES?

My interest in learning over networks dates back to 1989. In 1989 there was no commercial Internet. It was hard to get people interested in learning over networks or to even to understand what learning over networks meant or could mean. Fortunately, in 1992 I was joined at the Sloan Foundation by an extremely able program director, Frank Mayadas. Then we were able to get a real program started.

A Study of Heavy Metals Pollution in the Coastal Marine Sediment of Ondo State, Nigeria

The present study was carried out to assess the pollution status of heavy metals in the marine sediment in Ondo coastal area. A total of 36 sediment samples were collected from the three locations (Awoye, Abereke and Ayetoro) once in a month in 2015 covering both dry and wet season. The sediment samples were subjected to digestion and Atomic Absorption Spectrophotometer (AAS) was used to measure the concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn. The measured concentrations data were used for evaluating the contamination level and accumulation status of heavy metals in sediment by employing several pollution indices: contamination factor (CF), degree of contamination (Cdeg), pollution load index (PLI), enrichment factor (EF) and index of geoaccumulation (Igeo). The results showed that Fe had the highest average concentration values of 248.00§ 20.00 and 324.33§ 5.80 mg/kg at Awoye sampling site for wet and dry season, respectively while the highest mean concentration of Mn were 271.77±9.50 and 295±10.06 mg/kg at Abereke and Ayetoro, respectively. The contamination factor (CF) values for As, Cd and Mn were 1 &lt; CF &lt; 3, indicating a moderate contamination. The results of Cdeg were ranged from 8.6 to 12.5 for both dry and wet season except in Ayetoro site that had 7.8 in the wet season. The PLI values were 0.47, 0.50 and 0.54 (&lt;1) for Abereke, Awoye and Ayetoro sites, respectively, denoting unpolluted conditions. The EF values for Pb and Ni obtained from all the sites ranged from 20.8 to 38.9, showing their significantly enriched in sediment. The Igeo values of As, Cr, Fe, V, Zn and Cu were less than one (Igeo &lt;1) for the three sampling locations in both seasons, implying that the sediments in the study area are practically uncontaminated by these metals. Pb had the Igeo values of 2.80 and 2.85 during dry and wet season at Awoye sampling site while Ni had 2.57 at Abereke only in the dry season. The heavy metals in sediment might be derived from the upstream rivers from the top soil, mechanically weathered rock materials and anthropogenic activities.
A Convex Programming Approach for Discrete-Time Markov Decision Processes under the Expected Total Reward Criterion

In this work, we study discrete-time Markov decision processes (MDPs) under constraints with Borel state and action spaces and where all the performance functions have the same form of the expected total reward (ETR) criterion over the infinite time horizon. One of our objective is to propose a convex programming formulation for this type of MDP. It will be shown that the values of the constrained control problem and the associated convex program coincide. Moreover, if there exists an optimal solution to the convex program then there exists a stationary randomized policy which is optimal for the MDP. It will be also shown that in the framework of constrained control problems, the supremum of the ETRs over the set of randomized policies is equal to the supremum of the ETRs over the set of stationary randomized policies. We consider standard hypotheses such as the so-called continuity-compactness conditions and a Slater-type condition. Our assumptions are quite weak to deal with cases that have not yet been addressed in the literature. Examples are presented to illustrate our results.
Interval Tree and Its Application in Integer Factorization

The paper first puts forward a way to study odd integers by placing the odd integers in a given interval on a perfect full binary tree, then makes an investigation on the odd integers by means of combining the original properties of the integers with the properties of the binary trees and obtains several new results on how an odd integer&amp;#39;s divisors distribute on a level of a binary tree. The newly discovered law of divisors&amp;#39; distribution that includes common divisors between two symmetric nodes, genetic divisors between an ancestor node and its descendant node can provide a new and simple approach to factorize odd composite integers. Based on the mathematical deductions, numerical experiments are designed and demonstrated in the Maple software. All the results of the experiments are conformance to expectation and validate the validity of the approach.

Application of activated bentonite for the removal of direct and reactive dye from aqueous solutions

The aim of this study was to determine adsorptive properties of acid activated bentonite clay for the removal of Direct Red 173 (DR 173) and Reactive Red 22 (RR 22) dyes from aqueous solutions. Raw and modified clay were characterized by the following methods: Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRPD), and scanning electron microscopy (SEM). The efficiency of activated clay adsorption was investigated depending on process parameters: the adsorbent dose, pH, temperature, initial dye concentration, and contact time. Experimental data were analyzed by Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich isotherm as well as kinetic models of pseudo-first order, pseudo-second order and intra-particle diffusion. The process of dye adsorption was best described by Langmuir, Temkin, and Dubinin-Radushkevich isotherm (R2 &gt; 0.97). Pseudo-second order model (R2 &gt; 0.99) had the highest correlation with the obtained kinetic results. The positive value of ?H? indicated that adsorption of dyes by activated bentonite clay is endothermic process. The activated bentonite exhibited good regenerative ability in the 0.1 M NaOH solution. Maximum adsorption capacities of acid activated bentonite clay at 25?C for DR 173 and RR 22 dyes were 356.65 and 109.58 ?mol g-1, respectively.
