Factors Influencing Consumer ’ s Intention to Use E-payment System : An Empirical Study

UNNAYAN : International Bulletin of Management and Economics Volume IX | July 2018 (Special Issue) 14 In the recent years, electronic commerce (e-commerce) has growing rapidly. E-commerce became an opportunity for companies to increase their selling. E-commerce provides the capability of buying and selling products, information and services on the Internet and on other online environments. In an ecommerce surrounding, payments made in an electronic form, and are therefore called Electronic Payment. Electronic payment is a division of an e-commerce transaction to include e-payment for buying and selling of goods or services accessible through the internet. With the rapid growth of technology, the process to make electronic transactions are continuously increasing while the percentage of cash and cheques transactions continuously decreasing. Thus, the main objective of this paper is to explore the factors which influence consumer’s intention to use e-payment system for various purposes. Using principal component method of exploratory factor analysis, four factors viz. Perceived Usefulness, Perceived Social Esteem, Perceived Security and Perceived Reliability are identified that are affecting consumer’s intention. The research is mainly focused on primary data which were collected from e-commerce users through well structured questionnaire. The outcomes of this study are helpful to the users of e-payment system, researchers who will be working in this field and companies planning to adopt or to improve their electronic payment system. Keywords– E-Payment System, Usefulness, Social Esteem, Security and Reliability
Hemorrhagic Stroke of the Elderly Patient in the Department of Neurology, General Hospital of Loandjili, Pointe-Noire (Congo)

ABSTRACT Introduction. Hemorrhagic stroke (HS) is a serious condition that seems more common, in black African. Little is known about its features in the elder Congolese patients. The objective of the study was to report the epidemiology, clinical features and outcome of this disease in our setting at Pointe-Noire. Methodology. This was a cross sectional retrospective and descriptive study from January 1, 2017 to December 31, 2017 involving patients aged 60 years and over who had HS confirmed by cerebral computed tomography. Sociodemographic data, medical antecedents, severity signs and clinical course were collected and analyzed on SPSS software version 16.0 with uni and multivariate tests. Results: We studied 93 patients (62.7% women). Their mean age was 72.5 years (± 8.5). The main risk factor found was high blood pressure (98.9%). On cerebral computed tomography, 73.6% of hematomas were located in the capsulolenticulo-thalamic compared to 15.1% of cortical localization. The average hospital stay was 15 days. The lethality rate was 36.5%. Conclusion. At Pointe Noire, HS is a public health problem because of its frequency and its high lethality. High blood pressure is the main risk factor. Urgent measures are necessary to prevent its occurrence and improve its management for a better prognosis. RESUME Introduction. L’accident vasculaire cerebral hemorragique (AVCH) est une maladie grave, constituant 15 % des accidents vasculaires cerebraux (AVC). Il a une letalite elevee et donc un pronostic reserve, notamment chez le sujet âge. L’objectif de cette etude etait de decrire les aspects epidemiologiques, cliniques, paracliniques et evolutifs des AVCH du sujet âge a Pointe-Noire. Methodologie. Il s’agit d’une etude transversale retrospective et descriptive allant du 1er janvier 2017 au 31 decembre 2017 portant sur des patients âges de 60 ans et plus ayant presente un AVCH confirme par une tomodensitometrie cerebrale.

A cross-sectional study of the quality of root canal treatment in Al-Madinah Al-Munawwarah

Objective: This study evaluated the quality of root canal treatment (RCT) and determined the prevalence of apical periodontitis (AP) in Al-Madinah Al-Munawwarah, Saudi Arabia. Materials and Methods: Panoramic radiographs of 630 patients (316 males and 314 females) who attended clinics at the Dental College of Taibah University seeking dental care for the first time between 2010and 2013 were assessed for the adequacy of RCT and presence of AP. Results: RCT of at least one tooth was found in 52.8% of the patients, with a significantly higher prevalence in females (28.4 vs. 24.4%; P = 0.012), and AP was found in 53.5% of the patients, with a significantly higher prevalence in females (31.9 vs 21.6%; P = 0.000). Conclusions: There was a significant correlation between AP and inadequate endodontic treatment. This study reveals the importance of improving RCT in Al-Madinah Al-Munawwarah.
Detection of hypermucoviscous Klebsiella pneumoniae in camel (Camelus dromedarius) during an outbreak of acute respiratory tract infection

The present study was undertaken with an objective to identify hypermucoviscous (HMV) Klebsiella pneumoniae isolates in camels (Camelus dromedarius) suffering from acute respiratory tract infection in an outbreak form. Of the 96 nasal swabs from affected and 67 from healthy camels, 47 and 18 isolates of K. pneumoniae, respectively were obtained. Only 25 (53.19%) isolates of K. pneumoniae from acute respiratory tract infected camels and none from healthy camels showed existence of virulent HMV phenotype. Seven (14.89%) of the HMV phenotypes were also positive for virulent K5 serotype. All studied isolates did not show presence of K1 (magA gene), K2 and rmpA genes.
Lived Experiences of Undergraduate Medical Students About Hidden Curriculum: A Phenomenological Study

The hidden curriculum refers to student experiences that occur outside the formal structure of the curriculum, and especially the messages provided by the education system concerning values, perspectives, behaviors, and attitudes which has a strong influence on students' professional development. This study aimed at explaining the lived experiences of undergraduate medical students about the “hidden curriculum. ” This was a qualitative phenomenological study. Participants were medical students of Iran University of Medical Sciences and they were chosen by purposive sampling method based on the inclusion criteria. Semi-structured interviews with open-ended questions were conducted with 10 students until data saturation, and 7-step Colaizzi's method was utilized for the purposes of analyzing the study findings. In the process of analyzing data from medical students' lived experiences about hidden curriculum, the following three themes were extracted: 1. Conflict in value beliefs (sub-themes: not giving priority to students education, applicability to the clinical practice of basic sciences, attitude towards discipline, professional ethics, justice in evaluation”) 2. Modeling teacher’s communication skills patterns (sub-themes: “teacher-patient relationship,” “teacher -student relationship and professor-colleagues relationship) 3. Effective teaching (sub-themes: “clinical teaching” and “theoretical teaching”). Based on the results of the study, the hidden curriculum has both positive and negative impacts on various aspects of learning, especially the attitudinal domain. Consequently, paying specific attention to hidden curriculums is an absolute need. © 2019 Tehran University of Medical Sciences. All rights reserved. Acta Med Iran 2019;57(5):308-315.
Absorption and Scattering of Single Plasmonic Nanoparticles

Absorption and Scattering of Single Plasmonic Nanoparticles by Ji Won Ha In this thesis, I present the absorption and scattering properties of single gold nanoparticles. I performed scanning electron microscopy (SEM) correlated dark-field scattering studies of gold nanorods (AuNRs). I found polarization-dependent scattering of a single AuNR. I studied the dependence of surface plasmon resonance (SPR) linewidth on both the refractive index of a surrounding medium and the adsorption of thiol groups onto the surface of AuNRs. I found that the SPR wavelength (kmax) shifts to longer wavelength when increasing the refractive index of the surrounding medium, while the SPR linewidth remains almost constant when increasing the refractive index of the surrounding environment. I also found that SPR wavelength shifts to longer wavelength as thiol groups bind to the surface of a single AuNR and that the SPR linewidth is broadened. I carried out photothermal imaging of gold nanospheres. The successful imaging of gold nanospheres down to 10 nm, which cannot be studied by conventional scatteringbased methods, was achieved with a signal to noise (S/N) ratio of35. I studied the size dependence of the photothermal signal of gold nanospheres with diameters ranging from 30 to 250 nm. The experimental results showed a very good agreement with Mie calculations for absorption of nanospheres.
Title Life-style and travel demand : From Special Report 220 : A Look Ahead : Year 2020

Added to the original text) A fundamental solution to the issue of congestion cannot be reached without addressing the question of life-style. This paper reviews the definitions of life-style found in the literature, and identifies variables that have been commonly associated with life-style. Using US consumer expenditure data, life-styles are analyzed longitudinally (examining trends during the 1953–1983 time frame) and crosssectionally (comparing segments of the population stratified by income, life-cycle stage, and age), and likely relationships to travel behavior are noted. The usefulness of existing empirical findings to long-range forecasting is explored by speculating on shifts of behavioral units across life-style segments, and on shifts in the behavioral patterns within each life-style segment.
Evaluation of mechanical injuries in homicidal deaths (A retrospective study of 5 years)

Jamnagar region, Gujarat state, enjoys a relatively low incidence of homicide in India. The following study examined 120 cases, (67.04%) of homicides where death was produced by inflicting various mechanical injuries on the body, reported during the years 2000 to 2004. Incidence of homicidal deaths due to mechanical injuries was 24 cases per year. It formed about 2.89% of all the total medico legal autopsies conducted during the period. Mechanical injuries were quite common in homicidal deaths involving as many as 92 male and 27 female victims. Majority of the victims were in the age group of 21 to 40 years with 77 cases, (64.17%). Blunt force was the most commonly employed method seen in 58 cases, (48.33%). It was followed by sharp force seen in 38 cases, (31.67%) and sharp and blunt combine forces seen in 23 cases, (19.17%). Incidence of fire arm injuries was quite rare in the present study. Head injury was quite common in homicide. Maximum external injuries were seen on the head and mostly they were produced by hard, blunt and heavy weapons. Stab injuries were commonly seen on the chest and abdomen. In the present study 35 cases, (29.17%) showed presence of defence wounds. Defence wounds were commonly seen in the male victims.
Treatment failures? Scope of the treatment system for long‐term heroin addicts

In a study of 50 long‐term heroin addicts in Hamburg with an average usage period of 17.4 years, it was found that heroin usage patterns differed in the course of addiction. It appeared that two‐thirds of the sample had had longer periods of uncontrolled heroin use that were interrupted by phases of abstinence or by phases of controlled use. Almost all of them use different drugs. Currently, as well as in the course of their addiction, they use numerous other drugs in an uncontrolled way, especially benzodiazepines. Long‐term heroin addicts on the whole have less treatment experience than persons in the reference studies. The percentage of treatment dropouts is as high among them as among the persons surveyed in other studies. Completed treatment correlated with better results with regard to the duration of abstinence following treatment. The level of information regarding the pending treatment was low among long‐term heroin addicts.
It’s not only about the teacher! A qualitative study into the role of school climate in primary schools’ implementation of self-regulated learning

ABSTRACT Teachers play a key role in the implementation of self-regulated learning (SRL). Nevertheless, research has found that SRL implementation in primary schools remains limited. This qualitative study investigates the role of school climate, the SRL implementation history, and the role of the principal school leader in the school-wide development of SRL implementation as an educational innovation. A comparative analysis between 2 successful and 2 less successful schools as to the implementation of SRL was carried out. Interviews were administered with 15 school members. The results reveal that successful SRL schools distinguish themselves by a shared vision, sufficient and focused opportunities for professional development, and regular collaboration and communication among colleagues resulting in a collective feeling of responsibility for SRL implementation. Moreover, this is influenced by the school’s SRL development history and the supportive role of the school leader. The results underline the need for more school-wide interventions regarding SRL implementation.
1 Exceptional Prison Conditions and the Quality of Prison Life : Prison size and prison culture in Norwegian closed prisons

This paper discusses the quality of prison life and prison size in relation to the notion of ‘Scandinavian exceptionalism’. Using the questionnaires ‘Measuring the Quality of Prison Life’ (MQPL) for prisoners and ‘Staff Measuring the Quality of Prison Life’ (SQL) for staff, data were collected from all 32 closed prisons in Norway. Based on the assumption that prison officers’ working lives, their perspectives and values influence prisoners’ quality of life, the main focus in the paper is on the officers. Small prisons (fewer than 50 prisoners) obtain more positive results than medium-sized (50-100) and large (more than 100) prisons, on several dimensions measured. The relationship between officers and prisoners seems to be of better quality in small prisons than in medium-sized and large prisons. Officers in small prisons also report more positive relationships with senior management than their colleagues in medium-sized and large prisons. The results are discussed in light of previous studies on officers and prison working life dynamics.
Integrated Weed Management in Soybean on Farmers Field

Two weedings done 20 and 30 days after sowing gave highest weed control efficiency (85.6%), highest seed yield (1860 kg ha−1) and highest net return (Rs. 8086 ha−1). This was followed by pre-emergence application of pendimethalin at 1.0 kg ha−1 supplemented with one weeding at 30 days stage.
Pain that Lasts: The Long-Term Mental Health Implications of Childhood Bullying

The immediate effects of childhood bullying have been extensively researched and are relatively well-understood among the scientific community and within the public sphere. However, the long-term mental health effects of bullying are less understood and have only recently begun to be researched. Such implications require more attention from the scientific field to better recognize the effects of childhood bullying throughout a person’s lifespan. Recent research has shown that childhood bullying can lead to depression (Farrington, Loeber, Stallings, & Ttofi, 2011), anxiety (Heretick, 2012), symptoms of post-traumatic stress disorder (PTSD) (Dewey, 2015), and social isolation (Schafer et al., 2004) in adulthood. Furthermore, being at a higher risk of developing these mental illnesses in adulthood may seriously hinder one’s ability to function in society, specifically in environments such as work, family, and other social settings (Zlomke, Jeter, & Cook, 2016). Understanding the long-term mental health implications of childhood bullying can help parents, teachers, and professionals take greater action to create programs and initiatives that better confront the issue of bullying in schools.
Expertise on Boards and the Market for Directors with Acquisition Experience

We study whether firms construct boards that are consistent with the firm’s expertise needs. Using acquisitions as our setting and directors with acquisition experience, we document significant differences between the boards of acquiring firms and non‐acquiring firms. Consistent with the findings of prior research that firms choose boards based on the firm’s advisory and monitoring needs, we find that acquiring firms have more independent directors with acquisition experience. They also have directors who have been involved in larger deals. Frequent acquirers and firms engaging in large acquisitions have even deeper experience on their boards. However, we also find that experienced directors in acquiring firms tend to have been involved in significantly worse acquisitions compared to those in non‐acquiring firms. In the recruitment of directors, we show that experienced directors tend to join large firms that already have an abundance of experience on the board. Firms where agency problems are most severe systematically recruit directors who have been involved in value‐decreasing acquisitions and this result is largely driven by acquiring firms. Our findings offer an agency explanation for the absence of ex‐post settling up in the director labor market for directors with acquisition experience that has been documented in prior literature.

Car rentals constitute a significant portion of vacation travel expenditures. This research study uses a model developed in prior literature to explore the effects of vehicle brand, rental agency image, and rental price on consumers' willingness to rent automobiles. Results indicate that branding and price impact consumers' decisions to rent motor vehicles. However, the influence of the agency on the rental decision is limited. Managerial implications of these findings are discussed.

LEARNING EFFICIENT VISUAL EMBEDDING MODELS UNDER DATA CONSTRAINTS

LEARNING EFFICIENT VISUAL EMBEDDING MODELS UNDER DATA CONSTRAINTS Mert Bülent Sarıyıldız M.S. in Computer Engineering Advisor: Selim Aksoy Co-Advisor: R. Gökberk Cinbiş September 2019 Deep learning models require large-scale datasets to learn rich sets of low and mid-level patterns and high-level semantics. Therefore, given a high-capacity neural network, one way to improve the performance of a model is increasing the size of the dataset which the model is trained over on. Considering that it is easy to get the amount of computational power required to train a network, data becomes a serious bottleneck in scaling up the existing machine learning pipelines. In this thesis, we look into two main data bottlenecks that rise in computer vision applications: I. the difficulty of finding training data for diverse sets of object categories, II. the complication of utilizing data containing sensitive user information for the purpose of training neural network models. To address these issues, we study zero-shot learning and decentralized learning schemes, respectively. Zero-shot learning (ZSL) is one of the most promising problems where substantial progress can potentially be achieved through unsupervised learning, due to distributional differences between supervised and zero-shot classes. For this reason, several works investigate the incorporation of discriminative domain adaptation techniques into ZSL, which, however, lead to modest improvements in ZSL accuracy. In contrast, we propose a generative model that can naturally learn from unsupervised examples, and synthesize training examples for unseen classes purely based on their class embeddings, and therefore, reduce the zero-shot learning problem into a supervised classification task. The proposed approach consists of two important components: I. a conditional Generative Adversarial Network that learns to produce samples that mimic the characteristics of unsupervised data examples, and II. the Gradient Matching (GM) loss that measures the quality of the gradient signal obtained from the synthesized examples. Using our GM iii

This paper extends the prior studies on corporate performance by empirically exploring the impact of overall corporate governance structure on firm performance. To unveil the objective of this study, firstly corporate governance index is built using Principal Component Analysis with 6 (six) identified corporate governance mechanisms from prior studies and then examines its effect on firms’ performance. This study draws a sample of twenty-four (24) financial companies from the listed financial institutions in Nigeria for the period of 2013–2017. The formulated hypotheses are tested by employing static panel data estimators that are Fixed effect and Random Effect Regression. The results reveal that while controlling for firms’ characteristics, constructed corporate governance indicator has a significant and negative influence on the firm performance measured by Return on Asset and Return on Equity. This finding supports that larger board, larger board committees and significant executive involvement have a detrimental influence on the performance of firms. The result implies a weak corporate governance structure is detrimental to higher financial performance amidst the weak institutions characterized in Nigeria context. That is, weaker corporate governance exhibits lower financial performance. This study then recommends that the corporate governance structure in Nigeria listed firms should be review with the intention to enhance the firm performance. Furthermore, it encourages the regulatory agencies like Central Bank of Nigeria, National Insurance Commission and Securities and Exchange Commission, to monitor the compliance of the listed firms to good governance endeavour.
The Long-Run Impacts of Special Education

Over 13 percent of US students participate in special education (SE) programs annually, at a cost of $40 billion. However, due to selection issues the effect of SE placements remains unclear. This paper uses administrative data from Texas to examine the long-run effect of reducing SE access. Our research design exploits variation in SE placement driven by a unique state policy that required school districts to reduce SE caseloads to 8.5 percent. This policy led to sharp reductions in SE enrollment. These reductions generated significant reductions in educational attainment, suggesting that marginal participants experience long-run benefits from SE services. (JEL H75, I21, I28, J13, J14)
