A Review on the Antecedents and Precedents of International Students' Satisfaction in Malaysian Public Universities

Service quality is a vital feature for all successful higher education institutions, especially to improve the level of satisfaction among the international students in Malaysia due to the higher economic returns from international students. Students are constantly recognize as the prime focus in marketing activities in higher education institutions. However, the approaches of higher education institutions as the service provider varies.The quality of service will retain more foreign students to pursue their study in Malaysia. This paper will identify antecedents and precedents of the international postgraduate students’ satisfaction, i.e., this study will examine the relationship between service quality and behavioral intention which is moderated by students’ satisfaction. The interplay among the three constructs is based on the Resource Based View and Disconfirmation theories as well as the SERVQUAL model.
Enhancing the Performance of the BackPropagation for Deep Neural Network

The standard Backpropagation Neural Network (BPNN) Algorithm is widely used in solving many real problems in world. But the backpropagation suffers from different difficulties such as the slow convergence and convergence to local minima. Many modifications have been proposed to improve the performance of the algorithm such as careful selection of initial weights and biases, learning rate, momentum, network topology and activation function. This paper will illustrate a new additional version of the Backpropagation algorithm. In fact, the new modification has been done on the error signal function by using deep neural networks with more than one hidden layers. Experiments have been made to compare and evaluate the convergence behavior of these training algorithms with two training problems: XOR, and the Iris plant classification. The results showed that the proposed algorithm has improved the classical Bp in terms of its efficiency.

Relativistic fluid simulation of plasma-vacuum expansion with LTE closure

Neither kinetic numerical modeling nor widely available analytical models currently provide su�cient information on the timescale of interest for the plasma expansion phase in TNSA. In order to �ll this gap, this thesis introduces a uid approach to modeling plasmas that is easily implemented in simulations of arbitrary dimensions and can be used to simulate long timescale e�ects. The model has been implemented in a simulation that can simulate plasma expansion in arbitrary dimensionality. Section 2.1 introduces the general concepts of modeling collisionless plasmas as intersecting uids. First, the general description of collisionless plasmas by the Vlasov equation is given in section 2.1. 1. Next, it is shown how equations describing the evolution of ensemble quantities like particle density, momentum density and energy density can be derived from the Vlasov equation in section 2.1. 2. Next, the mechanics of TNSA are introduced along with its relation to laser intensity. Next, existing models for the plasma expansion phase are introduced, along with their assumptions and limitations. Finally, the theory section shows how the early stages of TNSA can be simulated using existing PIC codes. The methods section explains how the simulation using the LTE closure is built up in full. Section 4 discusses the veri�cation tests performed on the simulation code. Finally, in section 5 the simulation is used to investigate a simple one dimensional-expansion in comparison to the commonly used isothermal model. The di�erences between two-dimensional expansion and one-dimensional expansion are shown.
Feeding trial of instant food containing lyophilised yam powder in hypertensive subjects

BACKGROUND: It was reported in a previous paper that the yam tuber storage protein dioscorin exhibited antihypertensive effects on spontaneously hypertensive rats. The aim of the present study was to evaluate and compare the effects of packets of instant food (30 g) with (treated meal) and without (placebo) lyophilised yam powder on hypertensive subjects. RESULTS: A placebo-controlled feeding trial was conducted daily for 5 weeks (stage 1), followed by a 1 week washout and then a 5 week crossover (stage 2). Twenty-one subjects finished the trial. One packet of treated meal contained 140 ± 2.54 mg of dioscorin according to enzyme-linked immunosorbent assay. The blood pressure results of the treated meal and placebo groups at stage 1 end versus originals, but not at stage 2 end versus stage 2 beginning, were significantly different by the paired t test. Systolic (SBP) and diastolic (DBP) blood pressure readings after treated meal intervention, but not after placebo intervention, differed significantly from the original values based on one-way analysis of variance followed by the post hoc Tukey test; the reductions in SBP and DBP were 6.52 and 4.76 mmHg respectively. The feeding trial did not appear to affect serum lipid profiles or other biochemical measurements of cardiovascular risk. CONCLUSION: Intake of an instant food containing 140 mg of dioscorin over 5 weeks had a regulating effect on human blood pressure. Copyright © 2008 Society of Chemical Industry
Genetic diversity of European beech in Poland estimated on the basis of isoenzyme analyses

The aim of this study was the assessment of genetic diversity and differentiation patterns of European beech (Fagus sylvatica L.) populations within its natural range in Poland. These stands cover 5.2% of the forest area in Poland, and form the predominant forest tree communities throughout the Carpathians and Sudety Mountains, and the moraine landscape of the Pomeranian Lake District. Varying environmental conditions have resulted in a great number of ecotypes and populations which are characterized by various ecological requirements. Poland represents the northeastern limit of the beech’s natural distribution. Genetic diversity and differentiation was assessed using allozyme gene markers employing 9 enzyme systems: glutamate-oxaloacetate transaminase (GOT – EC 2.6.1.1), leucine aminopeptidase (LAP – EC 3.4.11.1), isocitrate dehydrogenase (IDH – EC 1.1.1.42), malate dehydrogenase (MDH – EC 1.1.1.37), menadione reductase (MNR – EC 1.6.99.2), phosphoglucomutase (PGM – EC 2.7.5.1), phosphoglucose isomerase (PGI – EC 5.3.1.9), peroxydase (PX – EC 1.11.17) and shikimate dehydrogenase (SKDH – EC 1.1.1.25). Beech populations occurring toward the northeast of the natural range were characterised by a decreasing the average number of alleles per locus and percentage of polymorphic loci. The highest genetic differentiation was found in the East Carpathians. The genetic differentiation levels of Polish beech populations are comparable to the other European countries.
Parties, mandates and multilevel politics

The three main statewide British parties – Conservatives, Labour and Liberal Democrats – all produce different versions of their manifestos in British general elections. Many policies debated in a British general election no longer apply at the subnational level, where separate devolved institutions control large areas of policy. This article therefore assesses the roles of national party manifestos at the subnational level in British general elections. It develops an original theory linking Strom’s alternative party goals to Ray’s typology of mandate/contract manifestos, advertisement manifestos and identity manifestos. It then explores a comparative overview of British parties’ general election manifestos at the subnational level, before focusing in detail on Labour’s 2010 and 2015 general election manifestos, which reflect the party’s strategic difficulties caused by devolution. The expected variation is found between the national and subnational manifestos. In some instances, multiple goals are pursued simultaneously and this is reflected in manifestos which assume elements of more than one manifesto ideal type. This supports the additional conclusion that manifestos can perform multiple functions in complex multilevel systems of government.
LBICA: A Load Balancer for I/O Cache Architectures

In recent years, enterprise Solid-State Drives (SSDs) are used in the caching layer of high-performance servers to close the growing performance gap between processing units and storage subsystem. SSD-based I/O caching is typically not effective in workloads with burst accesses in which the caching layer itself becomes the performance bottleneck because of the large number of accesses. Existing I/O cache architectures mainly focus on maximizing the cache hit ratio while they neglect the average queue time of accesses. Previous studies suggested bypassing the cache when burst accesses are identified. These schemes, however, are not applicable to a general cache configuration and also result in significant performance degradation on burst accesses.In this paper, we propose a novel I/O cache load balancing scheme (LBICA) with adaptive write policy management to prevent the I/O cache from becoming performance bottleneck in burst accesses. Our proposal, unlike previous schemes, which disable the I/O cache or bypass the requests into the disk subsystem in burst accesses, selectively reduces the number of waiting accesses in the SSD queue and balances the load between the I/O cache and the disk subsystem while providing the maximum performance. The proposed scheme characterizes the workload based on the type of in-queue requests and assigns an effective cache write policy. We aim to bypass the accesses which 1) are served faster by the disk subsystem or 2) cannot be merged with other accesses in the I/O cache queue. Doing so, the selected requests are responded by the disk layer, preventing from overloading the I/O cache. Our evaluations on a physical system shows that LBICA reduces the load on the I/O cache by 48% and improves the performance of burst workloads by 30% compared to the latest state-of-the-art load balancing scheme.
A new entropy model for RNA: part V, Incorporating the Flory-Huggins model in structure prediction and folding

The effect of solvent-biopolymer interactions is hardly negligible. Whereas the ideal (non-interacting) polymer consisting of N monomers in an ideal solvent is expected to have the terminal ends of its chain with a root-mean-squared (rms) end-to-end separation distance ( rms ) proportional to the square root of N , real interactions of a rms polymer both with itself and with the solvent often tend to strongly perturb rms . In rms poor solvent, the biopolymer can collapse into a small globule much smaller than the ideal rms due to excluding solvent. In good solvent, the biopolymer can swell to a size much larger than the ideal r due to favoring solvent. These effects require rms corrections to an ideal polymer equation. We have been developing the cross linking entropy (CLE) model in this series. The model attempts find the maximum entropy of a folded polymer by taking into account the correlation caused by bonding and other interactions of the structure. In RNA, this mostly occurs in the stems. Here we adapt CLE model to handle polymer swelling and collapse for RNA molecules both in good and in poor solvent. This work is intended to introduce this type of study and to allow its systematic application in problems of RNA folding and structure prediction. The current study suggests that there may be some tendency for RNA to behave as a polymer in poor solvent and that this collapse may happen in sequences longer than 50 nt.
A Hybrid Approach to Improve Student Navigation of Learning Materials in a Web 2.0 Environment

Tag-based folksonomy is commonly used in Web 2.0 technology but it lacks relationships among tags. We consider this weakness and propose to make use of the hierarchy concept from taxonomy to make-up the flat-level tag cloud diagram. A software tool is developed to quickly map individual tags to hierarchical concepts through word matching, and subsequently establishes relationship between folksonomy and taxonomy. Students will find it easier to locate and discover learning materials by relating tags to concepts and vice versa. Through this work, the tag quality is improved, leading to a better understanding on tagging.
Synchronization scenario of two distant mutually coupled semiconductor lasers

We present numerical and experimental investigations of the synchronization of the coupling-induced instabilities in two distant mutually coupled semiconductor lasers. In our experiments, two similar Fabry–Perot lasers are coupled via their coherent optical fields. Our theoretical framework is based on a rate equation model obtained under weak coupling conditions. In both experiments and simulations, we find (achronal) synchronization of subnanosecond intensity fluctuations in concurrence with asymmetric physical roles between the lasers, even under symmetric operating conditions. We explore the synchronization of these instabilities with respect to the coupling strength and the injection current. We demonstrate the existence of a critical coupling strength, below which synchronization is lost; however, dynamical instabilities persist. Our model correctly reproduces the observed dynamical features over the entire investigated parameter space. We provide an intuitive explanation of the appearance of the achronal solution by analysing the dynamics of the injection phases of the optical fields.
A gastric stump cancer with unusual appearance

A 60 year old man was referred to our hospital with the chief complaints of abdominal pain and vomiting. He underwent a distal gastrectomy with a Billroth II gastrojejunostomy for a peptic ulcer 13 years ago. Esophagogastroduodenoscopy (EGD) did not reveal any gross lesion in the stomach but depigmented areas were seen in the anastomosis line. The histopathology of the anastomotic area revealed poorly differentiated adenocarcinoma. Gastric stump cancers can be polypoid, fungating, ulcerated and diffusely infiltrating tumors respectively. In our case, the appearance of adenocarcinoma was quite different from that described in the classification system.
Utilizing an Exercise-Based Learning Tool Effectively in Computer Science Courses

Educational technology and learning environments are becoming more and more com- mon in all levels of education. Still, the main focus in research seems to be on which tools to use rather than how to effectively use them. In this paper, we first discuss the aspects that should be considered when adapting an exercise-based learning environment into curriculum. Based on our earlier research on the topic, we present three rules for adapting the tools. Next, a six-year study on using a learning environment in two courses is presented. Throughout the six course instances, the adaptation and integration of the tool is gradually altered. The results seem to confirm the positive effect of changes made in adaptation. When the three rules presented earlier are revisited in correlation with the results obtained, we can state that following the rules of adaptation lead to better student performance.
A Model for the Study of Knowledge Management Support Systems

"Knowledge markets" have been proposed as an organizational structure to promote knowledge exchange for increased organizational profitability and survivability. However, the economics and organizational behavior literatures in administered hierarchies suggest that knowledge markets and their component reward systems could suffer from a variety of abuses, inequities, and inefficiencies. These literatures, and the information systems investigations they have spawned, are parlayed into a model for knowledge management research.
Foraging Behaviour of Adult Female Apennine Chamois in Relation to Seasonal Variation in Food Supply

Ungulates modify their foraging in response to seasonal variations in local food resources, therefore their feeding behaviour may be used as an indirect, but effective indicator of forage quality and quantity (Owen-Smith, 1979). The food intake rate, together with the time devoted to foraging, determines the feeding efficiency of a herbivore (Owen-Smith, 1979). Moreover the food intake rate can provide an approximate indication of the quantity of ingested food. Adult female Apennine chamois, Rupicapra pyrenaica ornata (Neumann, 1899), kids, yearlings of both sexes and a few subadult males live in Alpine meadows above 1700 m a.s. l. from June to December. In the cold season they move to lower, but very steep slopes, thickly covered with deciduous and coniferous forests (Lovari & Cosentino, 1986). Our observations were carried out in summer (when high quality food
Age scale for assessing activities of daily living for older adults aged 75 years or older

The purpose of this study was to develop an age scale for assessing activities of daily living (ADL) among community-dwelling adults aged 75 years or older. Participants were 1006 older Japanese: 312 men (79.6 ± 4.3 years) and 694 women, (79.9 ± 5.5 years). Participants completed a battery of 8 performance tests related to ADL and the Barthel index (BI) questionnaire. Spearman rank-order correlation analysis was applied to obtain the correlation of the 8 ADL performance tests with the total BI score. Three variables were high rank-order correlated with BI, secondly those items were subjected to the principal component analysis. The weighted combination of the principal component scores was summed. Resulting in an ADL score (ADLS), women = 0.075 X1 – 0.082 X2 – 0.063 X3 + 0.124, men = 0.051 X1 – 0.105 X2 – 0.099 X3 + 0.249, where X1 = hand-grip strength, X2 = timed up and go, X3 = five-chair sit to stand. Individual ADLS was transformed to an ADL age scale (ADLA). The estimation was – 5.493 ADLS + 79.90 for women, and – 4.272 ADLS + 79.57 for men. Due to the distortion at the regression edges, the equation was corrected as suggested by Dubina et al. ADLA women after correction was = 0.447 (chronological age: CA) – 5.49ADLS + 44.17, men = 0.519CA – 4.27ADLS + 38.26. ADLA can be used to identify or monitor the characteristics of the ADL levels of physical abilities in older Japanese aged 75 years or older.
Implementation of Community-based Environment Sanitation Program ( Case Study in Benteng Sub-district , Kepulauan Selayar Regency , South Sulawesi Province )

Sanitation facts from WHO/ Unicef Joint Monitoring Program (2015) revealed that of 67% of world’s population had access to improved sanitation, while 20% still lack of sanitation facilities, and 13% still practice open defecation practice. Due to this, world citizens have a huge homework to fill out provision of 2.4 billion people of improved sanitation and encourage 940 million people to stop open defecation practice. One of the solutions for provision sanitation services and facilities is community-based sanitation program through hardware approach, where community became the subject on the establishment of sanitation facilities. More than 32% of Indonesian people who live in urban areas are infected by various diseases, poor sanitation, and poor hygienic (Cameron & Shah, 2008). The open defecation behavior can cause water pollution and even endangering human health. The open defecation behavior is a very serious issue and this is not only bad for the people who do not have toilets, but also those who have it, because the disease can be transmitted from human feces are exposed through the water (waterborne diseases), such as diarrhea, skin diseases, and so forth. As a consequence of poor sanitation and hygiene, Indonesia suffered a loss for approximately 56 trillion rupiah (3.6 billion USD) in 2006, an amount equivalent to 2.3% of Gross Domestic Product (WSP, 2008). Asian Development Bank report revealed that water pollution in Indonesia could lead to a potential loss of 45 trillion rupiah, or 2.2 percent of Gross Domestic Product (GDP). Then, based on data from the United Nations INFORMASI ART IKEL ABSTRACT
IPM synchronous machine drive response to a single-phase open circuit fault

This paper investigates the steady-state and dynamic response of an interior permanent magnet (IPM) synchronous machine drive to a single-phase open circuit fault. This fault results in rotational electromagnetic asymmetry on both the stator and rotor, making it difficult to analyze using classical dq-transformation techniques. This paper presents a new dq synchronous-frame machine model that is capable of handling this highly asymmetrical fault condition, including the effects of q-axis magnetic saturation. Fault responses with two alternative post-fault control strategies are investigated: (1) opening all of the inverter switches so that the machine behaves as an uncontrolled generator (UCG), with the two unfaulted phases connected to the inverter DC link via the anti-parallel diodes; and (2) shorting the two remaining unfaulted phases together using the inverter switches. Results of this investigation show that the fault response is generally more benign using the UCG control strategy, with significantly lower phase currents and pulsating torque than corresponding values delivered using the phase-shorting strategy.
Enhancement of hybrid solar cell performance by polythieno [3,4-b]thiophenebenzodithiophene and microplasma-induced surface engineering of silicon nanocrystals

We have developed a room temperature fabrication technique for hybrid bulk heterojunction solar cells based on silicon nanocrystals (Si-ncs) embedded in polythieno[3,4-b]thiophenebenzodithiophene (PTB7) and that exhibit a high open-circuit voltage exceeding 1 V. This type of device outperforms the open-circuit voltage of analogous devices based on Si-ncs within poly(hexylthiophene) (P3HT). We also demonstrate that three dimensional surface engineering of Si-ncs by microplasma processing in ethanol can be used to enhance the electronic interactions with PTB7, without using any surfactant, and increasing the power conversion efficiency.
Rotordynamic Stability Case Studies

In this article case studies are presented involving rotordynamic instability of modern high-speed turbomachinery relating the field data to analytical methods. The studies include oil seal related field problems, instability caused by aerodynamic cross-coupling in high-pressure, high-speed compressors, and hydrodynamic bearing instability resulting in subsynchronous vibration of a high-speed turbocharger. It has been shown that the analytical tools not only help in problem diagnostics, but also aid in problem resolution. Examples are presented showing how analytical methods, when appropriately applied, can solve rotordynamic instability and result in stable rotor system.
