EXAMINATION OF FACTORS AFFECTING ONLINE CONSUMER BEHAVIOR FROM THE PERSPECTIVE OF THE UNIFIED THEORY OF ACCEPTANCE AND USE OF TECHNOLOGY

Online consumer behavior and traditional consumer behavior are very different. Online consumer behavior evolves in the process of purchasing products or services over the Internet (Li and Zhang 2002). Consumer behavior has been a major area of research in the field of marketing knowledge, and studies of consumer behavior are based on many disciplines. With the rapid development of information technology, especially with the growth of e-commerce, more and more traditional consumers have become online consumers. Many younger generations are becoming online consumers when they first start shopping. A better understanding of online consumer behavior is both theoretically and practically important. The study aims to discuss the reasons for using or not using technology within the context of online consumer behavior by exploiting the Unified Theory of Acceptance and Use of Technology (UTAUT) scale. Upon testing the overall conceptual model, there is a significant relationship between performance expectancy, effort expectancy, social influence, and behavioral intention. There is also a significant relationship between facilitating conditions and use behavior. There is also a significant relationship between behavioral intention and use behavior. Upon considering the importance of information technologies in the online shopping process, based on the Unified Theory of Acceptance and Use of Technology, this study focuses on the factors that explain the intention to purchase online. This model contains the explanatory variables of the UTAUT (performance expectancy, effort expectancy, social influence and facilitating conditions) as the main * Öğr.

In this study, it is theorized that performance expectancy, effort expectancy, social influence and facilitating conditions play significant roles as direct determinants of user acceptance and use behavior. Based on the findings of the structural model; it is observed that performance expectancy, which is a strong intention indicator, has a positive impact on behavioral intention. The empirical results strongly supported the theoretical model.
Classification Based on Lyrics and User Interpretations

That music seekers consider song subject metadata to be helpful in their searching/browsing experience has been noted in prior published research. In an effort to develop a subject-based tagging system, we explored the creation of automatically generated song subject classifications. Our classifications were derived from two different sources of song-related text: 1) lyrics; and 2) user interpretations of lyrics collected from songmeanings.com. While both sources contain subject-related information, we found that user-generated interpretations always outperformed lyrics in terms of classification accuracy. This suggests that user interpretations are more useful in the subject classification task than lyrics because the semantically ambiguous poetic nature of lyrics tends to confuse classifiers. An examination of top-ranked terms and confusion matrices supported our contention that users' interpretations work better for detecting the meaning of songs than what is conveyed through lyrics.
Numerical Simulation of Two-Layer Fluid Natural Convection in a Side-Heated Enclosure using Lattice Boltzmann Method

In the present paper, natural convection in an enclosure of two immiscible fluids is simulated by lattice Boltzmann method with no a priori assumptions on the shape and dynamical role of the interface. Furthermore, the behavior of the interface is obtained as part of the solution. New two-phase thermal lattice Boltzmann method is proposed which is indeed the combination of isothermal two-phase lattice Boltzmann method and passive scalar approach. The present model is validated with the single-phase natural convection problem and good agreement is observed. The main objective of this study is to investigate the applicability of this new lattice Boltzmann model for simulating thermal two-phase problems. Furthermore, explicit influences of some nondimensional parameters are scrutinized. The flow patterns and temperature contours are visualized and averaged heat transfer coefficient along the vertical walls are obtained. It is found that with increase of Rayleigh number, the fluid motion becomes stronger and the isotherms are more distorted. Also with decrease of the aspect ratio and the ratio of Prandtl number of upper fluid to lower fluid, the circulating flow in both areas becomes weak. It is concluded that this new thermal lattice Boltzmann model has a great capability to model thermal two-phase problems.
DEVELOPMENT OF A 3 D FORCE-BASED BEAM ELEMENT FOR NONLINEAR ANALYSIS OF RC FRAME STRUCTURES CONSIDERING FLEXURE-SHEAR COUPLING

The applicability of fully 2D or 3D refined finite element models of reinforced concrete structures subjected to seismic loading is questionable, especially due to their high computational burden and inherent complexities involved in developing and running the model and interpreting the results. On the other hand, beam-column type finite elements developed in the framework of distributed plasticity, where the nonlinear response of the basic system is found from the integration of the response at control sections along the element axis, seem to provide the best compromise between the desired accuracy and computational efficiency. The present work starts with a review of the main features of the state-of-the-art distributed inelasticity beam-column formulations that include shear effects and presents the grounds on which the motivation for the development of a new model settles. One of such elements is then developed with a view to the seismic assessment of reinforced concrete frame structures. The proposed model is able to deal with arbitrary loading conditions and involves the interaction of axial force, shear, bending moment and torsion. Since shear-normal stress interaction is explicitly included, the current model is deemed suitable for shear critical member analysis.
Successful Students in an Open and Distance Learning System.

Learning in a higher education institution that applies an open and distance learning system requires the students to study as independent learners. This research is a survey research with the purpose of exploring the characteristics, habits and learning motivation of high-achiever students or those who obtained a high level of Grade Point Average (GPA). The sample used in this study was Universitas Terbuka (UT) students of Non Elementary Education Programs who had completed at least four semesters and had obtained a GPA of 2.50 or higher. This study discovered that the high-achiever students were younger students of the average age of 29 years. Most of these higher achiever students were highly motivated to study and were studying at UT to support their career development. They usually studied 3-4 hours/for each course each day. Interviews showed that students generally did the self-assessment tests and they regularly attended the tutorials. The time of study (p=.001) and methods of study (p=.01) recorded in this study have the potential to contribute to the students’ GPA.
EXTENSION OF FORM-BASED RELIABILITY TO BUILDING SEISMIC LOSS ESTIMATION AND PORTFOLIO RESILIENCE

An efficient process for estimating regional seismic loss is important, as many private and public entities are concerned with the impact of an earthquake to a portfolio of buildings. This paper begins with a brief review of structural reliability and the difference between reliability and resilience. It then touches on loss issues, followed by the introduction of the use of the First-Order Reliability Method (FORM) as a reliability tool and then its extension into resilience, where it can be applied to quantify the potential loss to a portfolio of buildings given either a known or probabilistic earthquake scenario. The FORM optimization process also provides a set of sensitivity measures, which capture the sensitivity of the estimated failure probability to changes in the load and capacity parameters. The augmentation of the FORM reliability method to address regional portfolio resilience is a natural extension of the structural reliability methods that have been developed over the past 40 years, developing from memberby-member behavior to building performance. ____________________ Professor, Dept. of Civil, Environ. & Arch.

High Efficiency Near-Infrared Single-Photon Detector Using a Sinusoidally Gated InGaAs / InP Single-Photon Avalanche Photodiode

Near-infrared (NIR) single-photon detector (SPD) with a high photon detection efficiency (PDE) offers the possibility to realize quantum information and communication technology (QICT), e.g. quantum key distribution [1]. An InGaAs/InP single-photon avalanche photodiode (SPAD) is the potential SPD that is practical and has a high figure-of-merit. However, it is difficult to achieve a high PDE using the InGaAs/InP-SPAD, because of a strong trade-off-relationship between the PDE and an afterpulse noise inherent in the SPADs. In the past decade, many approaches to suppress the afterpulse have been reported. Especially, the rapid gating operations, i.e. the sinusoidal gating [2] and the self-differencing techniques, [3] enable InGaAs/InP-SPADs to be gated at a gigahertz repetition frequency and to have a PDE of 10 ~ 20% at 1550 nm, while the afterpulse probability (AP) is limited to several percent. We are now interested in how high PDE can be eventually achieved with the rapid gating, keeping the AP low. A potential PDE of InGaAs/InP-SPAD is higher than 60% which corresponds to its own quantum efficiency (QE). However, an imperfect avalanche detection probability, α deteriorates the PDE. Here, α is the probability that a first excited single-carrier can grow into a detectably large avalanche signal. The major obstacles to obtain the perfect α are believed to be an excess noise (fluctuation of the internal avalanche gain of the SPAD) and a self-quenching behavior. Although α can be improved simply by increasing the reverse bias voltage applied to the SPAD, the AP is also increased. Here, we propose to increase an operation temperature of InGaAs/InP-SPAD in order to make the trade-offrelationship between the PDE and the AP better. At a high operation temperature, the trapped charges, which cause the afterpulse, relax quickly. This obviously results in the strong suppression of afterpulse. In this work, the InGaAs/InP-SPAD was operated at 273 K with the sinusoidal gating. Then, in order to apply the reverse bias voltage (excess voltage) higher than ever to the SPAD, we used a high-amplitude sinusoidal voltage (30 Vpp) at 0.993 GHz for the gating. PDEs at 1550 nm, the dark-count probabilities (DCPs), and APs are plotted as a function of the excess voltage in Fig. 1. The PDE of 39.2 % was achieved with the DCP of 1.8 × 10, and the maximum PDE of 40.3% was obtained at the excess voltage of 11.5 V. The PDE is two times higher than that previously reported in [4]. The high PDE offers efficient multi-fold coincidence count experiments. Thanks to the large amplitude and the very high frequency of the sinusoidal gate voltage, not only the high excess voltage but also the short effective gate width of 234 ps were achieved simultaneously (see the inset of Fig. 1(a)). The short gate width contributed to reduce the DCP even at the high operating temperature of 273 K.
Heat-stable and heat-labile antinutritional profile in Mucuna pruriens var utilis : Effected by germination

The seeds of different germplasm of velvet bean, an underutilized tribal pulse, collected from Western Ghats, India were germinated upto 120 h with a view to assess the extent of reduction/deactivation of both heat stable and heat labile antinutrients. The extent of reduction in the contents of heat stable ANF like total free phenolics, tannins, phytic acid, L-Dopa ranged from 69.5 to 75.7%; 62.3 70.7%; 60.67 82.81%; 34.8 58.4%, respectively; whereas the heat labile ANF’s like trypsin and chymotrypsin inhibitors reduced at the ranges between 67.5 -77.0% and 76.9 83.0%, respectively in the seeds subjected to prolonged germination (ie., upto120 h). Regarding lectins (phytohaemagglutinins) the reduction was registered upto 60% in all the studied germplasm except Thachenmalai (black coloured seed coat). Furthermore, significant positive correlation i.e. R2 > 0.791 was observed between the contents of antinutrients (x) and the period of germination (y) in the studied germplasm. However, it was less pronounced for L-Dopa content. To sum up, prolonging period of germination has significant reduction in the contents of ANF’s been noticed. Germination for five days was found to be one of the optimal, traditional and cost-effective alternate processing methods in deactivating these antinutrients for further product development to combat highly prevailing Protein Energy Malnutrition.
Dynamics of rotating horizontal convection with a moving heated surface

The dynamics of mechanically stressed rotating horizontal convection in a cylindrical enclosure is investigated numerically. The rotating cylindrical container has a differentially rotating base with a thermal forcing applied radially on the bottom boundary. The conditions on the other boundaries are thermally insulated. Axisymmetric numerical solutions showing a steady regime flanked by two unsteady regimes at both ends of the range of Rossby number investigated. The thermally direct mechanical forcing (positive Rossby number) enhances radially horizontal convection, whereas the thermally indirect (negative Rossby number) forcing reverses thermal gradient results in a heated region away from the edge of the container. A robust Nusselt number scaling of ∼ Q1/2 is observed at a high value of Rossby number for both thermally direct and indirect forcing.
On-Task and Off-Task Behavior in the Classroom: A Study on Mathematics Learning With Educational Video Games

When performing a task in the classroom, it is essential to place the focus on learning. In the classroom, it is possible to distinguish between time spent by students on-task and off-task. The former is the time in which the student is focused on the learning task; the latter is the remaining time in which they focus on other activities. Understanding the relationship between the two is a concern for teachers, especially for those who teach mathematics and other subjects that are often considered unattractive by students. Given the opportunity afforded by educational video games to motivate and engage math students, an educational drill-and-practice video game was used in this study to practice second-grade arithmetic and study the students' on-task and off-task behavior. We found that when practicing arithmetic using an educational drill-and-practice video game, time on-task decreases during an activity (30 minutes) as well as over the course of the school year (March to December). This study has implications for the length of mathematics classes at schools as well as the need to vary activities during a class.
Effect of mulberry varieties on commercial characters of bivoltine silkworm, Bombyx mori L.

The investigation was carried out to evaluate the nine mulberry varieties viz., Tr-8, Tr-10, V-1, C-776, China white, S-54, S-146, NS-2 and Sujanpur to find out the varietal difference on the growth and development of bivoltine silkworm hybrid CSR2 × CSR4 for commercial character expression. Mulberry variety China white was treated as control and the performance of selected mulberry varieties was compared with the control. Observations were made on twelve economically important traits of each stage viz., larval (larval weight and larval survival percentage), cocoon (cocoon yield per 10,000 larvae (by weight and by number), single cocoon weight, single shell weight and shell ratio percentage) and post cocoon (total filament length, non-breakable filament length and denier) and was analyzed both individually and cumulatively. The data was analyzed using Evaluation index (E.I.) method. Seven mulberry varieties recorded mean evaluation index (E.I.) values of >50 ranging from 50.01 to 60.29, whereas, control (Sujanpur) scored E.I. value of 35.10 only. Three mulberry varieties, S-146 (60.29), Tr-8 (52.42) and Tr-10 (52.17) recorded average E.I. value >52 for all the characters under sub-tropical conditions.

Autismo Attachment Behaviors in Children with Autism

This study investigated the attachment behaviors in children with autism. Ten boys with autism, 10 boys with Down syndrome and 10 boys with typical development who were around 4 years old, participated in the study. A free-play session, which consisted of five episodes, was used to observe the interactive behaviors between the child and the mother, and also an unfamiliar person (the stranger). No significant differences were found among the three groups concerning most of the attachment behaviors. However, the children with autism presented a higher frequency of avoidant behavior, only in the first episode. The comparison of differences inside the group showed that children with autism interacted more with their mothers than with the stranger. These results show the attachment behavior among autistic children with their mothers and the advantages of using a coding system that takes into account the particularities of this behavior.
Mechanics of Graphene Bubbles

Pressurized graphene bubbles have been observed in experiments, which can be used to determine the mechanical and adhesive properties of graphene. A nonlinear plate theory is adapted to describe the deformation of a graphene monolayer subject to lateral loads, where the bending moduli of monolayer graphene are independent of the in-plane Young’s modulus and Poisson’s ratio. A numerical method is developed to solve the nonlinear equations for circular graphene bubbles, and the results are compared to approximate solutions by analytical methods based on membrane and linear plate theories. The adhesion energy of mechanically exfoliated graphene on silicon oxide is extracted from two reported data sets. The strain distribution of the graphene bubbles and transport of gas molecules among the bubbles are discussed. Moreover, the effect of van der Waals interactions between graphene and its underlying substrate is analyzed, including large-scale interaction for nanoscale graphene bubbles subject to relatively low pressures.
Numerical simulation of a turbidity current flowing over a solid obstacle

Turbidity currents are often the main process for the transport and deposition of the sediments in narrow dam reservoirs. Turbidity currents with high concentration of suspended sediments follow the thalweg of the lake to the deepest area near the dam, where the sediments can affect the operation of the bottom outlet and the intake structures. The use of solid obstacles is one of the methods for the control of reservoir sedimentation. A two-dimensional (2D) numerical model based on unsteady Reynolds-averaged Navier-Stokes (RANS) equations has been developed for the simulation of turbidity currents driven by non cohesive sediment and flowing over a solid obstacle. The 2D unsteady RANS equations closed by a buoyancy-modified ε − k turbulence model are integrated in time with a second-order fractional step approach. The results of numerical model have been compared with experimental results. The calculated and measured velocity profiles, front velocities, and sediment depositional depth generally are in good agreement. This demonstrates that the present numerical model can be used for further study on the behavior of turbidity currents that encounter solid obstacles.

Correlation among Academic Procrastination , Personality Traits , and Academic Achievement

Procrastination is explained as a complex phenomenon with cognitive, affective, and behavioral components consisting of the intentional postponement of an intended course of action in spite of awareness of possible negative consequences. Procrastination on academic tasks is a common problem affecting learning and achievement of university students and may have an effect on students’ personality traits and their learning because it affects the self-efficacy, self-control, and organizational behavior of the students. Personality is regarded as an important individual resource in academic settings and plays an important role in students’ academic performance. Academic procrastination and personality traits are regarded as important factors affecting learning and achievement of university students, and has a strong link with them. In this study, the findings on the correlation of academic procrastination, personality traits, and academic achievement in a sample of university students are presented.
