The Impact of Entrepreneurship Education Programs on Entrepreneurship Intention: Updating the Field of Entrepreneurship Education

Entrepreneurship education programs have had an increasing presence in higher education institutions in the last few years. Despite their popularity and the rapid growth of these programs locally and internationally, the extent of their impact on entrepreneurship intention is still unclear. Thus, research findings continue to create conflict among researchers. This thesis meta-analyzed 47 effect sizes from 38 studies published from 2014 to 2018 to reveal the impact of entrepreneurship education on entrepreneurship intention in higher education settings. The results show clear evidence that entrepreneurship education affects entrepreneurship intention, the weighted mean effect size was found to be = .313 (lower limit = 0.262, upper limit = .364). Higher education institutions and government agencies should focus on these types of education programs to support the economy, innovation, and start-up businesses, and to attract companies locally. Discussion and research limitations are discussed in this thesis

On The Development Of Novel Multifunctional Max Reinforced Metals (MRMS) Matrix Composites

This work illustrates the synthesis and characterization of novel MAX reinforced metals (MRMs) composites. These composites were tested for their mechanical and tribological performance in ambient temperature. Synthesis and characterization of Bi-Ti3SiC2 and Ag-Ti3SiC2 was studied in Chapter 2. Both composites showed an enhancement in their mechanical and tribological behavior. For example, the addition of 20% Ti3SiC2 decreased the wear rate (WR) by ~12 times in Ag and ~33 times in Bi comparing with the pristine metal. In Chapter 3, Bi-Cr2AlC composites were studied and results had been compared to Bi-Ti3SiC2 composites. The addition of 10 vol% Cr2AlC was able to decrease the WR of Bi-composites by ~100 times as compared to the Bi metal. Chapter 4 reports the current progress of synthesis and tribological behavior of Al-V2AlC, Al-Ti3SiC2 and Al-Cr2AlC composites. The addition of MAX phase particulates enhanced the hardness and compressive yield strength of all the compositions. Al-V2AlC, Al-Ti3SiC2 and Al-Cr2AlC exhibit better tribological behavior compared with pure Al. The WR decreased significantly from 0.25 mm3/N.m to 1.1 X 10-3 mm3/N.m in Al-30%V2AlC. Similarly, the addition of Ti3SiC2 decreased the WR to 7.3 X 10-4 mm3/N.m in the Al-10%Ti3SiC2. In Chapter 5, comprehensive conclusion of this thesis and the future scope of study is discussed. Briefly, the addition of MAX phases has beneficial effects on the mechanical and the tribological behavior. However, there is an optimum concentration where the best results are found. That is mainly due to the nature of these phases where they perform much better at higher temperatures rather than room temperature

Adapting Nuclear Security Education Programs in Arab Countries

Recent times have witnessed considerable international efforts in developing and supporting nuclear security education. However, Arab countries continue to face certain obstacles in the development and implementation of nuclear security education programs. By providing an overview of the nuclear security program at Naif Arab University for Security Science, this study highlights the hurdles faced by Arab countries in implementing new academic programs and improving the quality of current programs in nuclear security. It also discusses the state of the art in nuclear security education and highlights important issues related to such education in the Arab world. However, the influence of nuclear security educational programs in Arab countries was not considered because it requires a separate, detailed analysis

Antiplatelet Intake Medications for Patients Undergoing Dental Surgery

This study aims at exploring the patients taking antiplatelet medications who are undergoing dental surgery, physicians and dentists must weigh the bleeding risks in continuing antiplatelet medications versus the thrombotic risks in interrupting antiplatelet medications. Bleeding complications requiring more than local measures for hemostasis are rare after dental surgery in patients taking antiplatelet medications. Conversely, the risk for thrombotic complications after interruption of antiplatelet therapy for dental procedures apparently is significant, although small. When a clinician is faced with a decision to continue or interrupt antiplatelet therapy for a dental surgical patient, the decision comes down to “bleed or die.” That is, there is a remote chance that continuing antiplatelet therapy will result in a (nonfatal) bleeding problem requiring more than local measures for hemostasis versus a small but significant chance that interrupting antiplatelet therapy will result in a (possibly fatal) thromboembolic complication. The decision is simple: It is time to stop interrupting antiplatelet therapy for dental surgery

E-evaluación a través de tabletas y teléfonos inteligentes: una evaluación de la actitud de los profesores

URL del artículo en la web de la Revista: https://www.upo.es/revistas/index.php/IJERI/article/view/3292This research assess the effects of training program based on the usage of the digital learning objects in teaching practice at the Northern Borders University staff. E Assessment through the tablets and smart phones and the teachers' attitudes towards such way of evaluation is the major objective of this study as the researcher expects that the assessment mechanism in the university through utilization of tablets and smart phones and its application will inevitably bring in a systematic improvement in the assessment and evaluation process of the curricula. Moreover, making use of the e learning objects in training will make a significant change in e training program of the university. Hence, the researcher has chosen voluntary random samples from the university teaching staff (men\women) from various different faculties (medicine, medical sciences, science, education and arts, business administration, home economics, and science and literature). These samples included 300 members of the teaching staff. In a group of 20 to 25 members, a personal training was conducted regarding the usage of tablets and smart phones and its applications in the assessment process. Each group participated by producing a complete e-assessment for their students in the Northern Borders University and by the e learning system i.e. Blackboard and Question Mark. The research also depends on the semi-experimental design of multiple groups and on testing the groups' pre and post achievement tests. In addition, the research identifies the level of the university teaching staff in using the tablets and the smartphones and its applications in the assessment process by the note card that the individuals have during the test.Esta investigación evalúa los efectos del programa de capacitación basado en el uso de los objetos de aprendizaje digitales en la práctica docente de la Northern Borders University.

Estas muestras incluyeron 300 miembros del personal docente. En un grupo de 20 a 25 miembros, se realizó una formación personal sobre el uso de tabletas y teléfonos inteligentes y sus aplicaciones en el proceso de evaluación. Cada grupo participó produciendo una evaluación electrónica completa para sus estudiantes en la Northern Borders University y por el sistema de e-learning, es decir Blackboard y Question Mark. La investigación se basó en un diseño semi-experimental de múltiples grupos y en la prueba de los grupos antes y después de las pruebas de rendimiento. Además, la investigación identifica el nivel del personal docente de la universidad en el uso de las tabletas y los teléfonos inteligentes y sus aplicaciones en el proceso de evaluación mediante la tarjeta de notas que las personas tienen durante la prueba.Universidad Pablo de Olavid

Sensors data collection framework using mobile identification with secure data sharing model

Sensors are the modules or electronic devices that are used to measure and get environmental events and send the captured data to other devices, usually computer processors allocated on the cloud. One of the most recent challenges is to protect and save the privacy issues of those sensors data on the cloud sharing. In this paper, sensors data collection framework is proposed using mobile identification and proxy re-encryption model for data sharing. The proposed framework includes: identity broker server, sensors managing and monitoring applications, messages queuing sever and data repository server. Finally, the experimental results show that the proposed proxy re-encryption model can work in real time

Online Learning Environments: Investigating the Factors Influencing Social Presence

Despite the decreasing rate of enrollment for face-to-face classes at higher education institutions, the last decade has seen an increase in enrollment for classes online. However, online learners suffer from several challenges, which may hinder desirable learning outcomes. These challenges include feelings of isolation as well as a lack of academic and social interaction, which has led to higher dropout rates and lower retention rates. All of these challenges have been associated with social presence, or a lack thereof, in online educational environments. Previous researchers have identified three indicators that influence social presence (i.e. affective association, interaction intensity, community cohesion). However, the way in which these factors were measured calls into question the validity of the research. Moreover, recent research has re-examined the original three indicators and added two additional indicators theorized to affect social presence (i.e. instructor involvement and instructor knowledge and experience), forming the social presence model (SPM). This study: 1) evaluated three scales to measure the three indicators of social presence; 2) examined the relationships of these three indicators to social presence; 3) developed two additional scales to measure the two additional indicators of social presence; and 4) inspected the full SPM. The participants of the study consisted of 411 students taking fully online courses in the United States. For the measurement models, the author conducted six item factor analytic models to evaluate the social presence construct scale as well as the five construct scales of the social presence indicators. The results indicated a good to excellent fit of the measurement models as well as high correlation coefficients between social presence and the original three indicators of social presence. Conversely, the results indicated lower correlation coefficients among the three original social presence indicators with the two additional indicators. To examine the structure of these relationships, the author conducted two structural equation models (SEMs). The first SEM inspected the three original factors, and the second SEM inspected the full SPM. The results of the first SEM indicated that the three social presence indicators are highly associated with social presence as well as with one another. They are statistically significant predictors of social presence; social presence is mostly affected by affective association (ß = 0.522, P < 0.001), community cohesion (ß = .226, p = .001), and then interaction intensity (ß = 0.163, p = .027). For the second SEM, the results indicated that affective association was found to be a significant predictor (ß = .507, p < .001); interaction intensity was not found to be a significant predictor (ß = .120, p = .080); group cohesion was found to be a significant predictor (ß = .173, p = .009); instructor involvement was not found to be a significant predictor (ß = .092, p = .120); and, finally, instructor knowledge and experience was not found to be a significant predictor of social presence (ß = .085, p = .098). Affective association, as demonstrated through means such as humor and self-disclosure, is the most critical among the five social presence indicators. Sharing attitudes, feelings, personal experiences, and interests with one another is a highly effective way to increase social presence. The higher degree to which online community participants feel part of a cohesive group, the greater the degree of social presence. When instructors deliberately design activities to encourage affective association, they will also, in effect, enhance the levels of community cohesion and intensity of interaction. Although the involvement of instructors and their previous knowledge and expertise in the field are contributing factors to positive outcomes in online education, they were not found to contribute as much as the three original factors. The author concludes by discussing the implications as well as the limitations of these findings and suggests future research

Minimally invasive approach for the management of right atrial angiosarcoma; A case report

Cardiac angiosarcoma is a rare primary cardiac tumor. Outcomes of minimally invasive resection of cardiac angiosarcoma are rarely reported in the literature A male patient aged 28 years old presented with a right atrial mass compressing the superior vena cava and associated with pericardial effusion. Pericardiocentesis was done, and a preoperative workup revealed no distant metastasis. We planned excision of the mass through a right mini-thoracotomy approach. Intraoperatively, we found the mass invading the entire atrial wall thickness, and excision of the mass with a reconstruction of the right atrial wall was performed. Minimally invasive resection of atrial angiosarcoma could be feasible. Atrial angiosarcoma could present with vague signs and symptom
