Subordination And Convolution Of Multivalent Functions And Starlikeness Of Integral Transforms

This thesis deals with analytic functions as well as multivalent functions de- �ned on the unit disk U. In most cases, these functions are assumed to be normalized, either of the form f(z) = z + 1X k=2 akzk; or f(z) = zp + 1X k=1 ak+pzk+p; p a �xed positive integer. Let A be the class of functions f with the �rst normalization, while Ap consists of functions f with the latter normalization. Five research problems are discussed in this work. First, let f(q) denote the q-th derivative of a function f 2 Ap. Using the theory of di�erential subordination, su�cient conditions are obtained for the following di�erential chain to hold: f(q)(z) �(p; q)z

The problem of top-down techno-centrism in pan-Arab news media

What drives the logic and culture of digitisation in pan-Arab news? Based on interviews conducted with Arab journalists and editors in London and Dubai, as well as focus groups with Arab students, this paper shows the prevalence of a top-down techno-centric approach in the pan-Arab news industry. We define this as the push for the adoption of technology in news to serve state funders of media organisations rather than audience interests. We identify three key features of top-down techno-centrism in Arab news organisations. These are: 1) perceiving audience apathy about news as a problem of technology rather than content, 2) seeking to expand digital following and deploying digital aesthetics in news in pursuit of prestige for state-funded media rather than of providing a public service, and 3) relying on flawed and limited data on audience attention, use and interest, including the conflation of social media metrics with audience figures and public opinion. This culture of pursuing new technologies in Arab news, we argue, fails to consider the perspectives and priorities of both journalists and audiences and ends up being a convenient strategy to evade fundamental questions in journalism pertaining to freedom, trust and public interest

The event, one of the first to be held face-to-face at LSE following COVID-19 restrictions, brought together scholars and journalists to explore different facets of the idea of the future as it relates to Arab media and cultures historically and into the present moment

Soft Skills Training Strategy and Its Effect on Nurse Interns' Civil Behavior

Contents: Soft skills are socio-emotional skills, essential for personal development and workplace success. While civility is defined as having respect for others, and it is necessary to bring attention to the importance of soft skills and civility and discuss its impact on teaching, learning, and patient outcomes.Aim: This study aimed to assess the effect of soft skills training strategies on nurse interns' civil behavior. Methods: The study was conducted at Ain-Shams University Hospitals, where nurse interns have their training, namely; Ain-Shams University Hospital, El-Demerdash hospital, Pediatrics Hospital, and Cardiovascular Hospital using a quasi-experimental one-group pretest-posttest design. The subjects of this study included all available nurse interns having their training in the settings mentioned above during the data collection period (the academic year 2017-2018). The study sample was 90 nurse interns, 35 males, and 55 females. The data were collected by using two tools, namely the soft skills elements questionnaire and the workplace civility index. Results: The study revealed a highly statistically significant improvement in nurse interns' total knowledge in the post and follow-up phases p<0.01 as compared to the pre-intervention phase. Also, there was a highly statistically significant improvement in nurse interns' soft skills in the post and followed-up phases p<0.01 as compared to the pre-intervention phase. In addition to a highly statistically significant improvement in nurse interns' civil behavior in the post and follows up phases p<0.01 as compared to the pre-intervention phase. Conclusion: Implementing a soft skills training strategy for nurse interns is effective to improve their civil behavior. Based on the study findings, it was recommended that soft skills training strategy should be applied in all nursing curricula. The faculty of nursing should be supplied with all the learning resources needed in the educational system to support the students’ soft skills development, and further studies should be developed to handle the barriers of implementation of soft skills training strategy in nursing education

The role and value of nurses in care provision: Views and expectations of Emirati Nationals in the western region of Abu Dhabi, United Arab Emirates

Background: Reliable health user information is needed to effectively organize nursing services and deliver quality patientcentered care. Nurse leaders of Al Gharbia Health Services (AGHS) noted that although budget data and general workforce information were readily available, detailed information about patient experiences, views, and expectations was lacking. Objective: This study aimed to obtain preliminary data regarding health and nursing service expectations of Emirati nationals in the remote western region of Abu Dhabi, United Arab Emirates (UAE). Methods: This study used qualitative descriptive methodology. Semi-structured interviews were conducted with a sample of Emirati families who had recently accessed AGHS. Interviews focused on service user understanding and expectations of the role of nurses, nursing services, and the health service overall. Results: Emirati nationals’ views and expectations regarding nurses’ role and function in the healthcare team were highlighted. Participants’ expectations and the attributes they valued were distributed across two distinct areas: clinical competence and the “softer” skills of compassion, caring, and respect. Conclusions: These findings facilitate understanding of the expectations of Emirati health service users. Importantly, the results counter regional perceptions of nursing under-valued as a servant role across the UAE and broader Gulf Cooperation Council region. The findings may inform a range of activities including: a large-scale survey regarding the views and expectations of Emirati health service users; pre-service nursing education and nursing in service development; and the recruitment of Emirati nationals to the nursing profession. Further investigation regarding perceptions and valuing of nursing within the Emirati community is warranted

Clinical Anxiety among Saudi Postgraduate Pediatric Dentistry Students in Jeddah City

Objective. To determine anxiety in relation to gender, Grade Point Average (GPA), level of education and academic and clinical situations in Jeddah, Saudi Arabia. Also, to identify academic and clinical anxiety levels among postgraduate pediatric dentistry students. Methods. A cross-sectional study at governmental training hospitals was conducted. All registered postgraduate students in pediatric dental programs during the year 2015-2016 were included in the study. A self-administered questionnaire was distributed electronically to 60 postgraduate pediatric dentistry students aged between 25 and 45 years old. The questionnaire is composed of 55 questions that investigated demographic data, academic and clinical related situations including investigations, diagnosis, treatment, and complications in treatment. Results. The study showed a higher anxiety level in younger age dental students (76.7% compared to 23.3%) and Saudi board residents (60%). Comparing gender differences in anxiety revealed that a significant difference (P≤0.05) was found and anxiety seems to be more among female dental students (2% very anxious, 64% slightly anxious, and 34% not anxious) as compared to male dental students (8% very anxious, 69% slightly anxious, and 23% not anxious). Conclusions. There was increased awareness, detailed understanding, and handling of the patients by senior postgraduate pediatric dentistry students compared to junior students

A Novel Secure Patient Data Transmission through Wireless Body Area Network: Health Tele-Monitoring

The security of sensitive data obtained from a patient has not been implemented properly because of energy issues of sensor nodes in Wireless Body Area Network (WBAN) and constrained resources such as computational power and low battery life. The main of this paper is to enhance the security level of data transmission between patient and health service provider by considering the availability of energy at sensor nodes. The proposed system consists of a hybrid Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC), which provides simple, fast and high cryptographic strength of data security. ECC is used for securing AES encryption keys, and AES algorithm is used for encrypting/decrypting text. A scenario where sensor nodes are continuously supplied energy from solar power is considered and based upon the energy availability; respective encryption technique is implemented. The result shows that the proposed EEHEE algorithm increases the encryption of the data file by more than 19% compared to the State of Art's solution. The proposed EEHEE system is 11% faster in encrypting data file and reduces the energy consumption by 34 % compared to the current best solution.  The proposed system concentrates on reducing the energy consumption in WBAN and increasing cryptographic strength to the system by using the hybrid symmetric and asymmetric algorithm. Thus, this study provides an efficient scheme to enhance security for real-time data transmission in telemedicine

Homing and reparative effect of intra-articular injection of autologus mesenchymal stem cells in osteoarthritic animal model

<p>Abstract</p> <p>Background</p> <p>This work aimed to study the homing evidence and the reparative effect of mesenchymal stem cells (MSCs) in the healing process of induced osteoarthritis in experimental animal model (donkeys).</p> <p>Methods</p> <p>Twenty-seven donkeys were equally divided into 3 groups based on the observation period after induction of arthritis (3, 6 and 9 weeks) to achieve different degrees of osteoarthritis. Each group was subdivided into three subgroups of three animals each based on the follow-up period (1, 2 and 6 months) after treatment. The induction was done through intra-articular (IA) injection of 2 ml of Amphotericin-B in both carpal joints. MSCs were harvested in a separate procedure, labeled with green fluorescent protein (GFP) using monster GFP vector and suspended in hyaluronic acid for IA injection. Treatment approaches consisted of cell-treatment using MSCs suspended in 3 ml of hyaluronic acid (HA) for the right carpal joint; and using the same amount of (HA) but without MSCs for the left contralateral carpal joint to serve as a control. Animals were assessed clinically and radiologically before and after treatment. Synovial fluid was also evaluated. Histopathologically; articular cartilage structural changes, reduction of articular cartilage matrix staining, osteophyte formation, and subchondral bone plate thickening were graded. Data was summarized using median and percentile for scores of histopathologic grading. Comparison between groups was done using non-parametric Mann Whitney test.</p> <p>Results</p> <p>The reparative effect of MSCs was significant both clinically and radiologically in all treated groups (P < 0.05) compared to the control groups. Fluorescence microscopy of sections of the cell-treated joints of all animals indicated that the GFP-transduced injected cells have participated effectively in the reparative process of the damaged articular surface and have integrated within the existing articular cartilage. The cells were associated with the surface of the cartilage and, were also detected in the interior.</p> <p>Conclusions</p> <p>Homing was confirmed by the incorporation of injected GFP-labeled MSCs within the repaired newly formed cartilage. Significant recovery proves that the use of IA injection of autologous MSCs is a viable and a practical option for treating different degrees of osteoarthritis.</p
