Alignment of Doctoral Student and Supervisor Expectations in Malaysia

Aim/Purpose This paper compares doctoral student and supervisor expectations of their respective roles and responsibilities in doctoral research supervision relationships in Malaysia. It identifies the areas, and the extent to which expectations align or differ. Background Incongruence of expectations between doctoral students and their supervisor has been cited as a major contributor to slow completion times and high attrition rates for doctoral students. While researchers urge the need for explicit discussion of expectations, in practice doctoral students and supervisors rarely make their expectations explicit to each other, and few researchers have examined the areas of alignment or misalignment of expectations in depth. Methodology Semi-structured interviews were held with fifteen doctoral students and twelve supervisors from two research-intensive universities in Malaysia. An inductive thematic analysis of data was conducted. Contribution This paper provides the first in-depth direct comparison of student-supervisor expectations in Malaysia. A hierarchical model of student-supervisor expectations is presented. Findings Expectations vary in the degree of congruence, and the degree to which they are clarified by students and supervisors across four different areas: academic practice, academic outcomes, skills and personal attributes, personal relationships. A hierarchical model is proposed to describe the extent to which both students and supervisors are able to clarify their mutual expectations arising throughout the doctoral student-supervisor relationship. Alignment of Doctoral Expectations 2 Recommendations for Practitioners Institutions should support discussions with both doctoral students and supervisors of expectations of their student-supervisor interactions, and encourage them to be more proactive in exploring their mutual expectations. Recommendations for Researchers Data is recommended to be collected from students who have recently completed their studies, given the observation that some student participants were uncomfortable speaking about their supervisors while still in the student-supervisor relationship. Impact on Society Opening opportunities for discussions of expectations by students and supervisors, supported and encouraged by the institutions within which they work, can help set the scene for positive and productive relationships. Future Research Findings indicate there is need to examine in depth the impact of gender, and the competing pressures to publish and graduate on time, as they relate to the student-supervisor relationships and experience.
EFFECTS OF SELF-EFFICACY ON SELF- EMPLOYMENT INTENTION OF RECENT GRADUATES IN NIGERIA

This study investigated the effect of self-efficacy on self-employment intentions of recent graduates. Using the descriptive survey research design, the study population includes National Youth Service Corps (NYSC) members of Ojo Local Government area of Lagos state. A sample of 130 was selected using the purposive sampling technique. The formulated hypotheses were tested using the simple linear regression and the independent sample t-test. The results showed that there was a statistically significant influence of self-efficacy on self-employment intention of Corps members of Ojo local government, Lagos state. A significant regression coefficient was found F (1.128)=29.72, p<. 05), with R 2 of . 19. This presupposes that19.0% of the variance in self-employment intentions is as a result of the self-efficacy of recent graduates. Also, a statistically significant difference in the self-employment intentions were found between male and female corps members (tcal(128) = 2.11 is greater than ttab=1.98, p < . 05). The study therefore recommended, amongst others, that institutions and the government should educate and devise a means by which they can increase the level of graduates and students’ self-efficacy which in turn will help shape their intention towards shaping career options after graduation. Similarly, effective entrepreneurship education and training for students and graduates to enhance their efficacy in performing specific tasks and roles of an entrepreneur will go a long way in boosting their self-employment intention and also aids them towards post graduate job creation ability rather than job seekers.
Development of a pH-Sensitive Indicator Label for the Real-Time Monitoring of Chicken Meat Freshness

Article type: Research Paper Introduction: Intelligent packaging could be used to control the environment of food products and inform consumers of food conditions. The present study aimed to design a simple pH-sensitive label in chicken package to demonstrate food spoilage by color change. Bromocresol green (BCG) is a pH-sensitive color indicator, which was used to detect chicken spoilage and attached to the inner side of the package. Chemical (pH and total volatile base nitrogen [TVBN]), microbial, and sensory analyses were performed at the intervals of zero, three, five, seven, eight, and 10 days of storage at the temperature of 4°C. Methods: On the first day, the TVB-N was 19 mg/100g, while it was measured to be 29 mg/100 g on day eight and 46 mg/100g on the last daIntelligent packaging could be used to control the environment of food products and inform consumers of food conditions.

Chemical (pH and total volatile base nitrogen [TVBN]), microbial, and sensory analyses were performed at the intervals of zero, three, five, seven, eight, and 10 days of storage at the temperature of 4°C. On the first day, the TVB-N was 19 mg/100g, while it was measured to be 29 mg/100 g on day eight and 46 mg/100g on the last dayy. According to the obtained results, the changes in the BCG color due to chicken spoilage were detectable by the naked eye, and the bacterial count was estimated at 6.62 Log10CFU/g. On day 10, the color of the indicator turned blue, and the total bacterial count reached approximately7.20 Log10CFU/g. In addition, significant correlations were observed between the TVBN, pH, and microbial and sensory analyses in the studied samples with the changes in the color of the indicator during storage. Conclusion: Due to the increased TVBN during storage, the color of the BCG indicator changed from yellow to blue. Therefore, the BCG indicator could be employed as an inexpensive, simple label to show the freshness of chicken meat.

Open-source, partially 3D-printed, high-pressure (50-bar) liquid-nitrogen-cooled parahydrogen generator

Abstract The signal of magnetic resonance imaging (MRI) can be enhanced by several orders of magnitude using hyperpolarization. In comparison to a broadly used dynamic nuclear polarization (DNP) technique that is already used in clinical trials, the parahydrogen ( p H 2) -based hyperpolarization approaches are less cost-intensive, are scalable, and offer high throughput. However, a p H 2 generator is necessary. Available commercial p H 2 generators are relatively expensive (EUR 10 000–150 000). To facilitate the spread of p H 2 -based hyperpolarization studies, here we provide the blueprints and 3D models as open-source for a low-cost (EUR <3000 ) 50-bar liquid-nitrogen-cooled p H 2 generator.
Supervisory Support for Ethiopian Doctoral Students Enrolled in an Open and Distance Learning Institution

Aim/Purpose This article reports on quantitative analysis of students’ perceptions on dimensions of augmented face-to-face support. It is built upon the findings from a larger research project that was undertaken to evaluate postgraduate support offered to Ethiopian doctoral students. Background Student support is critical for the delivery of any quality Open and Distance Learning (ODL) system. This is because there are numerous challenges that students enrolled especially in global South ODL institutions are faced with, which can impact negatively on their progress and throughput. Methodology In this article, the data from a quantitative questionnaire that was collected from a larger research project was used. The questionnaire asked students to respond to questions about their perceptions of the inclusion of face-to-face workshops. The responses were analyzed using the Statistical Analysis System (SAS), version 8.4 statistical package. Contribution This research exposes the benefits of supplementing distance postgraduate supervision with face-to-face tutorials. Findings The results show that the student-respondents, in general, experienced all five dimensions (‘supervision’, ‘student needs’, ‘facilitators’, ‘environment’, and ‘institutional support/access’) of face-to-face student support very positive. Recommendations for Practitioners As this inclusion of face-to-face workshops was found beneficial to the students who are geographically distant and at risk of digitally exclusion, the paper concludes by recommending that such approach should not be discarded but strengthened to supplement distance postgraduate supervision. Doctoral Student Supervisory Support 48 Recommendations for Researchers Replication of this study but focusing on the qualitative aspects of the five dimensions identified. Impact on Society Although this study is limited in scope to the Ethiopia project, implications for geographically distant education and support are relevant to Unisa and other ODL institutions in the global South. This may ultimately help inform distance learning efforts globally through augmented face-to-face supports. Future Research The study results revealed potential concerns regarding student age and registration timelines. Therefore, more specific research that explores age and registration is required.
The Role of Social and Place Identities towards Promoting Sustainability Approaches and Behaviors

The concept of sustainability is encouraged to preserve natural resources, social values, cultural heritage, and economic capital, which already exist to make available them for the next generations. Moreover, to enhance the level of sustainability in communities, numerous scholars indicated both individual and community identities play a crucial role. Sustainability is attainable and successful if there are compatibility and balance among cultural diversity, social justice, environmental responsibility, and economic equality as well as be able to attract people and appeared in their values and behaviors. Due to the critical role of social identity for improving the capacity of the people by changing their values and behaviors, it can be argued that social identity plays a vital role to achieve and support the concept of sustainability. Besides, place identity is linked to meanings and perceptions held by the people concerning their environment. Thus, the effect of social and place identities to achieve sustainable city has been identified as one of the urban design issues for contemporary cities. In this regard, the main aim is how social and place identities can contribute to promoting sustainability approaches and behavior in communities. The methodology of this study is an integrative literature review based on existing documents and studies. As a result, the research would convey to understanding the dynamic role of social and place identities for enhancing the level of sustainability in urban communities.
Quorum sensing inhibitory effects of vanillin on the biofilm formation of Pseudomonas fluorescens P07 by transcriptome analysis

Pseudomonas fluorescens is an important psychrotrophic food-spoilage bacterium. Quorum sensing (QS) enables bacteria to control various physiological processes. Hence, targeting bacterial QS would be a novel method to improve food quality. In this study, P. fluorescens P07 was treated with vanillin, which showed strong QS inhibitory activity, and its resultant effects on swarming motility, biofilm formation, and extracellular polymeric substance (EPS) secretion were measured. The mechanisms underlying the inhibitory effects were then explored by transcriptomic analysis. The results showed that vanillin had inhibitory effects on swarming motility, biofilm formation, N-acyl-L-homoserine Lactone (AHLs) and EPS secretion of P. fluorescens P07. The result of transcriptionomic tests indicated that the decrease in bacterial biofilm formation was probably due to the influence of vanillin on mobility, adhesion, chemotaxis, EPS secretion, and QS system of the bacteria.
Study on the Safety and Accuracy of Intracavitary Electrocardiography and Ultrasound in the Peripherally Inserted Central Venous Catheter tip positioning of Breast Cancer Patients

This study aims to explore the safety and accuracy of the intracavitary electrocardiography and ultrasound in the peripherally inserted central venous catheter tip positioning of breast cancer patients. A total of 176 breast cancer patients who were treated in the breast surgery department of our hospital from January 2018 to January 2019 were selected. They were randomly divided into the Electrocardiogram-UI group (n=88) and the control group (n=88). In the Electrocardiogram-UI group, the peripherally inserted central venous catheter tip positioning was under the guidance of the bedside Electrocardiogram combined with ultrasound, while the peripherally inserted central venous catheter insertion in the control group was performed by the traditional technology. The accuracy of peripherally inserted central venous catheter tip positioning, psychological state, anxiety, pain degree, and complications were compared between the two groups after surgery. The results showed that the positioning accuracy rate of the catheter tip in the Electrocardiogram-UI group was 99.40 %, while that in the control group was 92.10 %. In the control group, the accuracy rate of the catheter tip positioning in the 6th, 7th and 8th ribs was 20.30 %, 64.10 %, and 14.70 % respectively, while that in the Electrocardiogram-UI group was 32.20 %, 40.30 % and 19.60 % respectively, with a significant difference between the two groups. And 24 h before the catheter insertion, there was no significant difference in the anxiety scores between the two groups. However, 24 h after the catheter insertion, the anxiety and pain scores in the Electrocardiogram-UI group were significantly lower than that of the control group. In terms of the complications, in the first w, two patients in the Electrocardiogram-UI group had thrombosis, while four patients in the control group. No patients had the symptoms of the chest discomfort, arrhythmia, or infection in both groups. At the end of three and six mo, the incidence of thrombosis in the Electrocardiogram-UI group was significantly lower than that of the control group. The peripherally inserted central venous catheter tip positioning technology guided by Electrocardiogram combined with ultrasound is an ideal method for peripherally inserted central venous catheter insertion. It can improve the quality of life of the breast cancer patients and promote the prognosis of the breast cancer patients.
Collagen membrane versus platelet rich fibrin membrane in bone graft healing: An experimental study in sheep.

Background and objectives: Guided bone regeneration is a term used to define the use of barrier membranes to promote complete osteogenesis. The aim of study was to histologically com-pare the effect of platelet rich fibrin membrane and resorbable Collagen membrane on bone substitute healing.Methods: in this experimental study three sheep’s which their weighted between 60-70 kg were used. After intramuscular sedation and local anesthesia, eighteen defects were created about 8 mm in diameter and 5 mm in depth in the lower border of mandible. Six defects on each animal which three in right side and three in left side of the mandible. The defects were filled with Biphasic calcium phosphate bone substitute. The first defect was covered by platelet rich fibrin membrane, the second one covered by Collagen membrane, and third one was left uncovered. The animals were sacrificed at 2, 6, and 12 weeks.Results: The healing of the grafted defects was histologically studied in all groups, and there was non-significant difference between PRF membrane and collagen membrane in healing of bone substitute at 2, 6, and 12 weeks.There was significant deference between PRF membrane and collagen membrane at 6 week regarding scaffold replacement with mature bone.Conclusion: The use of PRF membrane shows a good outcome as a low cost biological material capable of improving bone healing defects, grafted with bone substitute.
All You Need is Self-Determination: Investigation of PhD Students’ Motivation Profiles and Their Impact on the Doctoral Completion Process

Aim/Purpose The present study aimed at (1) identifying the naturally occurring patterns of motivation among doctoral students and (2) assessing their impact on the doctoral completion process. Background Grounded in the self-determination theory, the paper investigated needs satisfaction and the doctoral completion process. Methodology Two complementary methods were used. First, k-mean clustering was used to classify 461 doctoral students according to their feelings of competence, autonomy and relatedness. Second, the completion process of these five profiles was investigated through multi-group path analyses. Contribution This paper provided a motivational perspective on doctoral completion process that highlighted significant individual differences. Investigation of PhD Students Motivation Profiles 190 Findings Five profiles were identified corresponding to different combinations of satisfaction of their innate psychological needs. The results also revealed significant differences in the completion process from one motivation profile to another. Recommendations for Practitioners The doctoral supervision needs to consider the specificities of the patterns of motivation among doctoral students. Recommendations for Researchers A more important investigation of motivational patterns is required to fully understand the doctoral completion process. Impact on Society A better consideration of motivational profiles would increase doctoral students’ well-being and their persistence. Future Research The effect of motivation and context on student satisfaction and professional efficiency could be further explored.
Why should we care about academic integrity in nursing students?

Integrity, honesty, and respect are essential values for nursing students. Yet, in recent years the rise of breaches in academic integrity has become alarming. The era of increasing advances in the capabilities of smart technologies may be facilitating rather than deterring students from academic integrity breaches in their work and assessments. This issue raises questions for nurse academics on how they can best ensure that nursing students align their behavior with the expected nursing’s professional values, both during their study years and beyond. This discussion paper aims to examine contributing factors leading to breaches of academic integrity amongst nursing students and determine why we as nurse academics need to both remain alert to these factors, and vigilant about identifying and managing such breaches. Existing factors that may influence academic dishonesty are discussed concerning students; nurse academics; curriculum design; and the apparently growing cultural shift in ethical reasoning. With increased insight into these influencing factors, nurse academics need to take responsibility and prepare students to take on the highest standard of moral values to ensure safe and effective patient outcomes. We need to become more aware of and understand nursing students’ perspectives and adequately prepare our soon-to-become nurse graduates. We are charged with supporting, guiding, and teaching our students to develop skills within a culture of integrity. Ensuring an integrity activity smorgasbord in our practice can counteract the increased risk of academic dishonesty in our undergraduate nursing programs.
Manifestly Altered MicroRNAs in Poly Cystic Ovary Syndrome

http Introduction Polycystic ovarian syndrome (PCOS) is a common heterogeneous endocrine disorder in women during reproductive ages. Principally, there are three diagnostic criteria proposed by different groups including the National Institute of Health/National Institute of Children’s Health and Disease (1), the European Society of Human Reproduction and Embryology/the American Society of Reproductive Medicine (2), and the Excessive Androgen Association and PCOS (3). The prevalence of PCOS ranges from 6 to 20% given the type of the applied criteria (4-6). According to all available criteria, the diagnosis of PCOS is usually based on dysmenorrhea, hyperandrogenism, and polycystic ovary detected by sonography. The typical symptoms of PCOS include oligomenorrhea, amenorrhea, hirsutism, acne, overweight or diabetes, and infertility. Currently, the exact cause of PCOS is unknown. Epidemiological studies suggested that the PCOS profile risk relies on familial history, overweight and obesity (7-9), and diabetes (10). Post-transcription regulation by microRNAs (miRNAs) has been important research over the past 10 years. miRNAs constitute a large family of small noncoding RNAs with a length of 19-25 nucleotides (11,12). The production and function of miRNAs are shown in Figure 1. miRNA genes are usually transcribed by the RNA polymerase II/III and bound to pri-miRNA. They are then processed by Drosha in order to convert to pre-microRNAs. Next, they migrate to the cytoplasm and are changed into mature miRNAs by the Dicer. In addition, miRNAs attach to the 3’ UTR region of target genes causing the total or partial inhibition of gene transcription (13). The total inhibition of miRNA relies on the extent that miRNA complements mRNA and is rarely observed in animals. Thus, the effect of miRNA on mRNA transcription mostly occurs through suppressing and reducing transcription (14). The regulatory mechanisms of miRNAs have been extensively studied in the development of diseases, especially cancers. However, the possible regulatory patterns of miRNAs in PCOS have been poorly examined and require further studies. Different studies have reported contradictory results on miRNAs in various samples of blood, plasma, serum, ovaries, and to the same extent, in different ovarian components including follicular fluid, granulosa cells, blastocyte, and oocyte (15-18).
