THE IMPACT OF PROGRESS FEEDBACK ON SELF REGULATED GOALS AND PERFORMANCE OF POSTGRADUATE RESEARCH STUDENTS

The demand for a continuous consideration of postgraduate supervision has risen because of the various problems reported in numerous studies, such as the high rate of dissatisfaction and attrition, supervisors’ inadequate knowledge about practical aspects of candidature, and unsatisfactory levels in obtaining feedback about students’ performance and progress. These studies indicated that giving and receiving constructive and ongoing feedback between supervisors and students plays an essential role in identifying both parties concerns. For postgraduate research students, the nature of their task requires them to work more independently. Thus, self-regulating learning becomes important, particularly at the early stages of the study where students start to set their study goals, and the social support of the supervisor becomes in need. Self-regulating learning is the process of setting a goal, employing goal-directed actions, monitoring strategies and adjusting them to ensure success. This paper discusses the effect of supervisor feedback on the student’s self-regulation based on a review of the literature of self-regulation theory, and how receiving positive or negative feedback may affect student’s goal setting and performance during the postgraduate study.  Article visualizations

Surface morphology modifications of human teeth induced by a picosecond Nd:YAG laser operating at 532 nm

AbstractThe interaction of an Nd:YAG laser, operating at 532 nm with 40 ps pulse duration, with human teeth was studied. The results show that teeth were significantly modified at an energy fluence of about 11 J/cm2. Various surface morphologies of enamel and dentine were recorded. Features on enamel include crater (conical form) in the central part and cauliflower morphology at the periphery, whereas on dentine the crater looks like a stretched dome between sharp edges. The behavior of the enamel-dentine junction area showed different morphology with respect to both tooth enamel and dentine alone. Finally, the junction channel showed a removal of collagen fibers and the formation of a needle-like bottom structure. Generally, this investigation showed that the picosecond Nd:YAG laser can ablate a tooth surface practically instantaneously, implying that large tooth surfaces can be processed in short time

USING AUGMENTED REALITY TO ENHANCE THE CONVENTIONAL GAMEBOOK

Abstract This paper presents the design of Augmented Reality gamebook to enhance the performance of the conventional gamebook and replace it. Augmented Reality technology that employs animation in real scenes is to bring new digital entertainment experience to the viewers. Traditional gamebooks started to experience bored, become less attractive to gamers and easily obsolete. The conventional way of playing game does not satisfy the players anymore, it is because the interaction between the game and the player is limited to static objects such as text. Augmented Reality with its special characteristics enhancing the display output of real environment and the composition of virtual and reality can bring sense of deeper immersion to the players, thus greatly increasing the interest and attraction of game

The Role of Metamodeling in Systems Development

Software systems developers are encountering different challenges as systems become increasingly complex due to numerous customers' needs that lead to a system with rich functionalities to be delivered within a short schedule. Developers also have to manage a variety of implementation methods, design techniques, and development processes. Researchers proposed “languages” as a solution to these problems. Meta-modeling is a method for defining the abstract syntax of a language. It makes the development of a language simpler allowing the designers to directly map the classes identified in domain analysis to classes in the meta-model. The meta-model expresses what models include such as concepts, relationships between them, and maybe the rules of how these concepts can be interrelated. This article presents an overview of the role and importance of meta-models in system development and their relationship with modeling languages. It highlights different aspects of metamodels standards, categories, and challenges in the research of meta-modeling

Social Services for Sexual Minority Youth: Preferences for What, Where, and How Services are Delivered

As part of an internet-based study to investigate experiences of sexual minority youth in the U.S., 544 youth, ages 14-19, were surveyed about their need for services, where they preferred to receive these services, and their preferred method of service delivery. The survey was anonymous and youth were recruited from LGBTQ-specific listservs and venues as well as through social networking sites as a way of reaching youth often not represented in LGBTQ surveys. Youth highly endorsed many types of services, settings, and modes of delivery. Some subgroup differences emerged. Transgender youth and those uncertain about their gender identity expressed stronger interest than others in services to address stress, family issues, and self-defense, and in receiving support and guidance from LGBTQ adults. Few differences in service preferences along demographic lines such as race/ethnicity emerged; however, African American youth were more likely than others to prefer services offered in a place of worship. Contrary to predictions, geographic and community variables were not related to service type, delivery format, or location preferences

Molecular study of resistance genes in Escherichia coli isolated from chronic respiratory disease cases in broilers

Chronic respiratory disease is famous in poultry farming, mainly in broiler farms. The disease is caused by Mycoplasma species in participation with E. coli. Our study was conducted on CRD of broiler chickens to isolate and determine the resistance of Escherichia coli Seventy-four swabs of the internal organs of broilers (severe respiratory signs) were collected from different areas of Mosul from September 2021 to March 2022. MacConkey agar was used with cefotaxime (1 μg/ml) to grow the isolates, and they were incubated at 37 °C for 24 hours. Colonies were identified according to standard bacteriological methods. The cefotaxime-resistant E. coli isolates underwent DNA extraction. The polymerase chain reaction of Escherichia coli isolates was used for confirmation. The results of the existing study revealed that 61 samples appeared positive for bacterial isolation from 74 (82.4%). All isolates were resistant to an arsenal of antibiotics when testing their sensitivity to antibiotics, including azithromycin, levofloxacin, gentamycin, chloramphenicol…ext. Molecular detection of resistance genes showed that all isolates contained the CTX-M gene by 100%. In comparison, the TEM gene appeared in 52 isolates (85.25%), and only 9 (14.75%) isolates showed the SHV gene. In conclusion, our results shed light on the serious problem in poultry fields, which showed that Escherichia coli isolates contain genes with high resistance to antibiotics, which are the most widely used in the treatment of bacterial infections in these farms, which means the demand for introducing more novel antibiotics in the cure of poultry health problems

Knowledge, attitudes and beliefs related to drugs among Pahang Matriculation students in Malaysia

Introduction Drug abuse has been a global threat not only in Malaysia but worldwide, especially among adolescents. This is alarming issue had been a serious public health problem worldwide. The aim of the study is to access the knowledge and attitude on drug abuse among Pahang Matriculation students in 2016. Methods A cross¬-sectional study was conducted involving 217 matriculation students. A self-determined questionnaire was distributed among the students regarding knowledge and attitude about drugs. Results The prevalence of good knowledge on drug abuse was (82.03%). The prevalence of students’ attitude on drug abuse has higher number of good attitude with the sum of 182 (83.9 %). Only gender showed a significant association with students’ knowledge (P= 0.046). Conclusion The knowledge, attitude, and practice of drug abuse among Pahang Matriculation students are good
