Motivation-based IS evaluation strategy : a perspective of marketing information systems

The article describes the importance of motivational factors through an analysis of the core TAM constructs in the context of marketing IS evaluation. We argue that our findings compliment current IS evaluation strategy, specially for measuring motivational elements for online IS. The study consequently provides an empirical validation of the importance of motivational and behavioural factors. Through an experimental analysis we evaluated the relative importance of perceived enjoyment with perceived usefulness of using an online website for shopping purposes and found that enjoyment was by far the dominant predictor of attitude towards online shopping. The result illustrates that in terms of IS evaluation online environments have moved from being functional online applications to being functional, engaging and interactive online IS (e.g. websites).
Analysis of Two-phase E-core Switched Reluctance Machines Using Magnetic Equivalent Circuit Technique

The modification of magnetic structures for an E-core switched reluctance machine (SRM) comprising two segmented stator cores or a monolithic stator core is presented for ease of assembly, good manufacturability, mechanical robustness, and electromagnetic performance improvement. The E-core stator has four small poles with phase windings and two or four large poles (hereafter referred to as common poles), in between. The common poles are shared by both phases for positive torque generation during the entire operation. The E-core SRMs are compared to a conventional two-phase SRM. The comparison includes cost savings, torque, copper and core losses, and efficiency in order to validate the distinct features of the E-core SRMs. Magnetic equivalent circuit (MEC) technique is employed for proving the benefits of the E-core common-pole structure.

Developing curriculum design expertise through teacher design teams

To foster the design and especially the implementation of curriculum reform, teacher involvement from the early stages of curriculum reform processes is advocated. By fulfilling the role of designer, it is expected that teachers’ understanding of the reform and their ownership concerning the reform are being promoted. However, most teachers lacked the knowledge and skills needed for proper curriculum design. The assumption underlying this study was that teachers need to develop their curriculum design expertise to be able to cope with the problems encountered in design processes and to create quality curriculum materials. The study was guided by the main research question: “What opportunities do TDTs provide for teachers to develop curriculum design expertise? ” For answering the main research question a mixed-method approach was conducted. Four studies were conducted during a project in which Teacher Design Teams [TDTs] collaboratively designed curriculum materials that were attuned to the Common European Framework of References for languages. The curriculum materials they developed included language tasks, assessment rubrics and vision documents. The TDTs received tailored support during the project. The results showed that teachers as designers have to deal with design challenges when they design curriculum materials. These challenges consist of the decisions they have to make about the curriculum materials and the design process. Teachers’ ability to tackle design challenges is affected by teachers’ prior expertise in curriculum design for collegial purposes, their pedagogical content knowledge and their curriculum design expertise. Teacher involvement in a TDT provides teachers with various opportunities to learn about curriculum design and the curriculum reform, which helps to develop their curriculum design expertise and PCK. These activities include using exemplary materials, sharing experiences about the design process with teachers outside the TDT, evaluating the curriculum materials and using the materials in classroom practices. Thus, although teacher involvement offers opportunities to develop teachers’ curriculum design expertise, their involvement in a TDT as such is often not enough. Just-in-time support offered to TDTs has to focus on the activities that are not (yet) part of teachers’ repertoire and need to be offered in the form of concrete tools.
Analysis of the Inner Flow in the Wave Energy Converter WaveTube

Wave energy technology is currently growing and gaining popularity. With around 100 separate technologies researched globally in over 25 countries wave energy are believed to soon be able to compete with other renewable sources such as wind energy. One of the new technologies is WaveTube; a wave energy converter currently under development and in need of technical verification. The basic idea of WaveTube is a partially submerged container with an enclosed fresh water volume. The kinetic energy of the ocean waves are transferred onto the floating container, creating an inner flow in the structure and electricity is generated as the fresh water flows through turbines.Previous small-scale model tests have confirmed the basic idea of WaveTube and an inherent continuation is visualizing and evaluating the inner flow using Computational Fluid Dynamics. A simplified 2D simulation where the WaveTube structure is subject to a pure sinusoidal, rotational motion was believed to be able to give useful information about the inner flow field. However, this Master Thesis project shows that a simulation using ANSYS Fluent of this case is not a successful approach. With inner moving parts a so called dynamic mesh was required, which updates the mesh as the boundaries move. In order for this method to be successful the mesh needs to be of high quality. However, for the complex geometry that WaveTube is no mesh was found to meet the requirements and the calculations using the Volume of Fluid method were not able to proceed.
Estimated impact of the 1978 UMWA contracts on the cost of mining coal. Analysis memorandum AM/ES/78-10. [1978 UMWA contract]

This analysis points up not only the major impact of productivity assumptions on the estimated cost of coal but also the indicated significance of regional variations. The large increase in coal production in the 1960's has been followed by a period of major changes in the industry in the 1970's. The latter include significant shifts in the method, size, and location of mining. Additionally, the past five years have witnessed a large decline in the share of coal production accounted for by the UMWA. Accordingly, there is a real need for greater study of the impact of the above developments on productivity-bach short-term and longer range. This conclusion is pointed up by the major shifts in productivity between 1968 and 1976 that are shown in the previously cited Table B.
Self-similar traffic analysis at network layer level. Part I: Fundamentals

Traffic streams, sources as well as aggregated traffic flows, often exhibit long-range-dependent (LRD) properties. This paper presents the theoretical foundations to justify that the behavior of traffic in a high-speed computer network can be modeled from a self-similar perspective by limiting its scope of analysis at the network layer, given that the most relevant properties of self-similar processes are consistent for use in the formulation of traffic models when performing this specific task.
Closed loop vibrational control: Theory and applications.

Abstract : In this project, a novel control technique, referred to as Closed Loop Vibrational Control, is developed and applied to the problem of fuselage vibrations suppression in helicopter dynamics. This technique is applicable to systems where the control input enters the open loop dynamics as an amplitude of a periodic, zero average function, and this amplitude can be chosen to depend on the systems outputs. An example of such a system is the helicopter with Higher Harmonic Control (HHC) where periodic feathering of rotor blades around a fixed pitch angle is introduced in order to suppress the fuselage vibrations. For systems with this structure, a number of control-theoretic problems, including - theoretic problems, including stabilizability, pole placement and robustness, have been solved, and the results are reported in this document. Vibrational control, Vibrational stabilizability, Robustness, Higher harmonic control.

Hypothesizing High Negative Emotionality as a Function of Genetic Addiction Risk Severity (GARS) Testing in Alcohol Use Disorder (AUD)

An estimated 14.5 million United States (U.S.) citizens ages 12 and older consume enough alcohol to meet the diagnosis for alcohol use disorder (AUD), as reported by the Center for Behavioral Health Statistics and Quality in 2018. A National Survey on Drug Use and Health (NSDUH) conducted in 2019, revealed that 85.6 percent of adults admit to consuming alcohol at some point during their life, 69.5 percent of adults admit to having consumed alcohol within the past year, and 54.9 percent (51.0 percent of adult females and 59.1 percent of adult males) self-report to have consumed alcohol within the past month. The survey also reported that among adults, 25.8 percent (22.2 percent of adult females and 29.7 percent of adult males) reported engaging in binge drinking within the past 30 days. The survey also revealed the 6.3 percent of adults (4.5 percent of adult females and 8.3 percent of adult males) reported to engage in heavy alcohol use within the past 30 days [1]
Biodynamic response of the human hand-arm models under vibration

This paper describes the development of hand/arm mechanical models, to investigate the biodynamic response characteristics in a 2 and 3 degree-of-freedom (DOF) of the human hand and arm system. The assessment of the vibration behavior is examined by using two models. Typically, the human is modeled as a second order mass-spring-damper system. In this study, 2- DOF and 3-DOF biomechanical models have been developed to derive the vibration transmission characteristics of the hand-arm. The resulting mode shapes are discussed from the viewpoint of the vibration response behaviour of the hand-arm that are presented in the time and frequency domains.
Optimal allocation of multiple DGS in RDS using PSO and its impact on system reliability

This article presents the distributed generator (DG) integration in a radial distribution system (RDS). The DG penetration changes the single power source to multiple power sources and bidirectional load flow which enhances the system reliability and reduces system power losses. The particle swarm optimization and gravitational search algorithm are implemented for the optimal siting and sizing of one and three DG units in the RDS to examine its impact on system reliability and loss reduction. The types of DGs considered are Type I (injects real power) and Type IV (injects reactive and real power). The constant power is the chosen load model. The reliability indices taken for the analysis of system reliability are Average Energy Not Supplied, Total Energy Not Supplied and Average System Interruption Duration Index. The efficacy of the proposed method is validated on 33-bus in the presence of single and multiple DGs. The significant decrease in system power losses with the upgraded bus voltage profile, system reliability and remarkable annual loss saving is analyzed for Type IV DG over Type I DG. The results determined are compared to other meta-heuristic approaches as well as analytical techniques to demonstrate the superiority of the proposed methodology. The results are also statistically verified.
Maternal and Paternal Parenting and Child Prosocial Behavior: A Meta-Analysis Using a Structural Equation Modeling Design

Abstract The current meta-analysis examined and compared the relative associations of maternal and paternal parenting behavior with children’s prosocial behavior from 29 studies. In total 502 effect sizes (N = 14,627) were subjected to Meta-Analytic Structural Equation Modeling. Controlling for the other parent, both maternal and paternal parenting behavior showed small positive pooled associations with children’s prosocial behavior (r father = .10 and r mother = .12). The partial effect sizes for paternal and maternal parenting did not differ significantly from each other and were significant regardless of parenting dimension, study design (concurrent versus predictive) and average sample age (pre-adolescence versus adolescence). High levels of paternal and maternal warmth and positive control, and low levels of paternal and maternal harshness were associated with more prosocial behavior in children.

Mathematical and numerical modeling of the AquaBuOY wave energy converter.

This paper presents the mathematical modeling and numerical methodology performed prior to the prototype deployment of the AquaBuOY, one of the few wave energy devices that have reached the ocean deployment stage. The combination of numerical computations, and laboratory testing produced some encouraging findings about how the AquaBuOY responds to real wave conditions. However, it also highlighted deficiencies in some of the early modeling, which emphasized the need for a time domain model in realistic wave conditions that includes accurate hydrodynamic and drag coefficients. This paper focuses on the governing equations that model the vertical dynamics of the AquaBuOY and the numerical solutions of these equations in order to predict the absorbed power of the device. Numerical results are presented in the time domain for both regular and irregular wave regimes (realistic wave conditions) as well as compared to experimental data in a regular wave regime. While the two body system is challenging to model, due to the inclusion of variables such as the wave forcing term as well as identifying the non linear damping term along with a linear spring term needed to model the power takeoff system, it does provide a robust tool for wave energy research.
An experimental evaluation of an instructional packet on supervised occupational experience programs for beginning vocational agriculture students in Iowa

3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap. If necessary, sectioning is continued again — beginning below the first row and continuing on until complete.

PHOX2B expression in bone marrow and peripheral blood is associated with metastasis and prognosis in patients with neuroblastoma

Background Paired-like homeobox 2B (PHOX2B) is specifically expressed in the nervous system including neuroblastoma cells, but little is known about the clinical significance of the expression of PHOX2B in bone marrow (BM) and peripheral blood (PB) samples of newly diagnosed neuroblastoma patients. Methods The expression of PHOX2B in 276 paired BM and PB samples of neuroblastoma patients at diagnosis was tested by quantitative reverse transcriptase polymerase chain reaction (RT-PCR). Then the relationship between PHOX2B level and clinical characteristics including metastasis and prognosis was explored by receiver operating characteristic (ROC) analysis and Kaplan-Meier method. Results We identified the combined expression of PHOX2B in both BM and PB provided a high diagnostic accuracy for metastasis of neuroblastoma patients (AUC = 0.920) with the sensitivity and specificity of 86.7% and 92.9%, respectively. At last, 246 patients were enrolled for prognostic analysis. The median follow-up time was 22 months. Positive expressions of PHOX2B in BM and PB at diagnosis were associated with worse EFS and OS in neuroblastoma patients (P < 0.05). What’s worse, 19.7% (31/157) and 6.4% (10/157) patients with positive expression of PHOX2B in BM and PB samples in low/intermediate-risk group also had shorter EFS and poor OS (P < 0.05). CONCLUSIONS The expressions of PHOX2B in BM and PB were high in patients with unfavorable clinical characteristics. PHOX2B could be an appropriate biomarker for predicting metastasis and prognosis in patients with neuroblastoma.
Education for Sustainable Development in Secondary Education of the Flemish Community: Challenges and Perspectives

Abstract Environmental Education is one of the cross-curricular themes, introduced in the mid 1990s in the curriculum of Flemish secondary education (12-18 yr). Both the Brundtland report and the ENSI philosophy inspired the development of the objectives for EE. A strong partnership exists between the departments of education and the environment of the Flemish Ministry and the provincial authorities, which resulted in the project ‘MOS’, an environmental management system for primary and secondary schools. Besides environmental objectives, the pedagogical objectives of the project are strongly emphasised. The UN Decade of Education for Sustainable Development provides a strong stimulus to link Environmental Education to the other cross-curricular themes, Citizenship and Health Education and to include the ‘MOS’-project into the broader framework of Education for Sustainable Development.
Simulated annealing in sonar track detection

Abstract : Classical edge detectors cannot handle the problem of noisy sonar track detection because they are too sensitive to noise. This thesis uses Simulated Annealing for the solution by formulating the sonar track detection problem as an optimization problem. the experimental results are much better than those of classical edge detectors. Fairly good results can be obtained on data with SNR down to -18 dB where most classical edge detectors fail.
Prevalence of Gross Motor Dysfunction in School Going Children with Flatfoot

Background: Arches of foot play an important role in our daily gross motor activities such as walking, running, jumping and standing and also act as shock absorber. Flat foot creates motor difficulties in activities require balance and stability as flatfoot alters the body’s weight distribution and transmission mechanism. The children with flatfoot may have difficulty in lower limb gross motor function, any study has not been conducted on this topic previously, so indeed this made us to study the prevalence of gross motor dysfunction in school going children with flatfoot. Objectives: To determine flatfoot in school going children (seven-twelve years). To determine prevalence of gross motor dysfunction in school going children with flat foot. Method: Total 80 students were taken from different schools in this study having flat foot in age group of 7-12 years of age and both male and female students were taken. They were asses by using plantar arch index for flatfoot and were given lower extremity function scale questionnaire to fill. Later evaluation of gross motor dysfunction were done by analysis. Result: The overall prevalence of moderately difficulty in physical activities was 8.37%, quite difficulty was 1.18%, little bit of difficulty was 16% and no difficulty was 73.5%. No significant difference were found in age wise and sex wise distribution with physical activities. Conclusion: On the bases of the result it conclude that the difficulty is seen particularly in activities which requires dynamic stability than static stability activities in children with flat foot.
Dynamic Power Oscillation Reduction using PSOA-PI in UPFC

The power flow control is one the important part of power system to maintain power system stability. If the real power and reactive power can be controlled then the automatic control of the power system gives numerous possibilities. The Flexible AC Transmission System (FACTs) are the devices meant for this operation. There are series and shunt type of FACTs devices available. The Unified Power Flow Controller (UPFC) is one of the best devices in FACTs devices in AC power system. The power flows can be controlled in series and shunt connections using the two converters. The power oscillations are common in UPFC when the reference powers are changed. The PI controllers are replaced with PSOA tuned PI controller to reduces the power oscillations and reduces the settling time. The problem is formulated to minimize the settling time of the power value. The series and shunt controllers are tuned with particle swarm optimization algorithm (PSOA) to tune the PI controller parameters available in it. The MATLAB Simulink version 2017b is used here for the analysis and well known UPFC test system with three generators are used here for testing the proposed method. The results show PSOA tuned PI controller provides better oscillation damping with reduced settling time.
