A Substitution-Box Structure Based on Crowd Supply Infinite Noise TRNG

Practical applications in cryptology science have a very wide spectrum. One of the important primitives based on many of these applications is the substitution-box structures. Since substitution-box structures are the main component targeted by many attacks, developing new substitution-box structures resistant to new attack is a hot research topic. Random selection-based designs have become increasingly popular recently, as they are more resistant to side channel attacks than mathematically based designs. In this study, a random selection-based substitution-box structure is proposed. The proposed substitution-box is designed based on a true random number generator hardware. Analysis results showed that the proposed substitution-box has better performance criteria than many designs in the literature. These successful results indicate that the outputs of study can be used successfully in many practical applications that will be designed in the future. � 2021 IEEE.

Suicidal behaviours among deaf adolescents in Ghana: A cross-sectional study

Background: A growing global concern is that suicide research has paid little attention to young people with disabilities, particularly, in low-and middle-income countries (LAMICs). We aimed to estimate the 12-month prevalence of suicidal ideation and attempt and describe some associations among deaf adolescents in Ghana. Methods: This is a cross-sectional anonymous self-report survey involving a nationally representative random sample of 450 school-going deaf adolescents. Data analysis included bivariate and multivariable approaches. Results: The overall 12-month prevalence of suicidal ideation was 19�3% (95% confidence interval [CI] = 15�8-23�3) and suicidal attempt was 15�6% (95% CI = 12�3-19�2). Although alcohol use and parental divorce were strongly associated with increased odds of both suicidal ideation and attempt, high subjective mental well-being was associated with reduced odds of both suicidal ideation and attempt. Living with no parents and being a final year student were associated with suicidal ideation, while male gender was associated with suicidal attempt. Conclusions: The prevalence of suicidal behaviours among school-going deaf adolescents in this study compares with estimates among in-school non-deaf adolescents in Ghana and other LAMICs in Africa, and also highlights the need for prevention efforts against the onset of suicidal ideation and possible transition to attempt and suicide among deaf adolescents. � 2021 The Author(s) 2021.

Supervision of teaching practice as experienced by student teachers and college tutors the case of Offinso College of Education

The purpose of this study was to explore the perception of student teachers on the nature of teaching practice they undertake and the nature of supervision they receive during practicum. The population of the study comprised final the year students of Offinso College of Education who had their teaching practice in the 2014/2015 academic year numbering 300 and all the tutors numbering 59.The sample for the study comprised 100(83%) student teachers and 30(51%) college tutors. The instrument used was a questionnaire and simple random sampling technique (The lottery method) was used to select student teachers and college tutors who were involved in the study. To achieve the purpose of the study, a descriptive survey design was used. A perceived quality of supervision model was adapted and used to measure the quality of supervision rendered to student teachers during practicum. Specifically, the model was used to collect data to measure the perception of student teachers as compared to supervisors. The model was adapted from a conceptual model of service quality (SERVQUAL) developed by Parasuraman, Berry, and Zeithaml (1985) The findings showed that the overall perception about the quality of the supervision function of the teaching practice programme fell below expectation in all the five quality dimensions measured. The study showed that there was a positive relationship between the professional development of teacher trainees and the teaching practice they undertook. However, the size of the effect or impact was not that significant. Based on the findings of the study, it was recommended that the college supervisors or tutors must work hand in hand with head teachers of the schools in which student teachers are posted to identify areas of professional growth and development.

Supervisors understanding and practice of their instructional leadership roles and their knowledge and use of clinical supervision in supervising teachers

The study was designed to find out how basic school supervisors understand and practice their roles as instructional leaders and their knowledge and use of clinical supervision in supervising teachers. The design was a descriptive survey and data was collected using quantitative and qualitative methods. The sample comprised126 participants and 111 of them comprising 83 teachers, 22 headteachers and 5 circuit supervisors and 1 head of inspectorate returned their questionnaires. A five-point likert scale with 38 questionnaire items was used to collect quantitative data while a semi-structured interview was used to collect qualitative data. Descriptive and inferential statistics were used as the statistical tools for analyzing quantitative data while a content analysis was used for the qualitative data.Findings indicate that most basic school supervisors who participated in the study understand and practice their roles as instructional leaders. On clinical supervision the study revealed that although basic school supervisors surveyed had knowledge about clinical supervision they were unable to use it properly in supervising teachers. The study further revealed that majority of teachers received support from their supervisors. Additionally supervisors and teachers had open and trusted professional relationships. Based on the findings and discussions the study recommended among other things that basic school supervisors must be trained in contemporary supervisory practices such as instructional leadership and clinical supervision so that they can improve supervision in basic schools. Heads of basic schools must also be fully detached to make them more effective while the size of circuits should also be reduced so that circuit supervisors can effectively monitor instructional delivery and support individual teachers. The study also suggests the need to conduct further research to find out the challenges facing basic school supervisors in the use of clinical supervision.

Supply chain disruption and performance the role of information technology and supply chain managerial capability

The dynamic and uncertain business landscape renders companies susceptible to supply chain disruptions. The complexity and dynamism of supply chains, intensified by globalization and technological progress, further escalate the risk of such disruptions. Notably, the healthcare supply chain has encountered severe setbacks due to disruptions like the COVID-19 pandemic, leading to medical supply shortages, heightened costs, reduced revenue, and decreased patient satisfaction. This upheaval has underscored the vulnerability of supply chains, necessitating enhanced resilience and preparedness. This study delves into the impact of supply chain disruption on supply chain performance, examining the mediating role of supply chain managerial capability and the moderating effect of information technology. Rooted in structural contingency theory and dynamic capability, the research formulates and investigates five objectives and corresponding hypotheses. Employing an explanatory research design with a quantitative approach, the study collected primary data through standardized questionnaires completed by 289 professionals from various health facilities in Ghana. Utilizing SmartPLS 4 for data processing and partial least square-structural equation modelling (PLS-SEM) for analysis, the hypotheses were tested. Findings revealed that supply chain disruptions significantly influence supply chain performance in the healthcare sector. However, this impact is reduced by information technology, and supply chain managerial capabilities act as a partial mediator in this relationship. Supply chain disruption negatively affects both supply chain performance and managerial capabilities. Remarkably, supply chain managerial capability transforms this negative effect into a positive one on performance. In light of these outcomes, the study underscores the importance for policymakers, practitioners, and management to closely monitor supply chain disruptions, given their adverse effects on supply chain performance. Furthermore, the study highlights the significance of fostering supply chain managerial capabilities to enhance network performance during disruption.
