Factors influencing the adoption of social media marketing in small and medium-sized enterprises during the COVID-19 pandemic in Saudi Arabia : a thesis presented in partial fulfilment of the requirements for the degree of Master in Business Studies at Massey University, Auckland, New Zealand

The COVID-19 outbreak led to a global economic slowdown that affected many countries including Saudi Arabia where trade, investment, employment, and travel have all been impacted by the lockdown, especially on small and medium-sized enterprises (SMEs). The main purpose of the current study is to examine the factors that influence the adoption and use of social media marketing (SMM) in SMEs during the lockdown in Saudi Arabia. This study has used a combined developed model from the Technology Acceptance Model (TAM) and Unified Theory of Acceptance and Use of Technology (UTAUT2) to examine whether SMEs in Saudi Arabia accept and use SMM effectively in the case such as COVID-19 pandemic, and to test its impact on improving the business performance through attracting new customers, sales, improved communication with customers, identifying customers' needs, and utilizing employees' creativity. This model succeeded to explain the Impact On Business (IOB) to a degree of 81%, since the coefficient of determination (R²) is 0.81. This study used a quantitative method by applying the Structural Equation Modelling (SEM) technique to validate the conceptual model. The data was collected by using an online questionnaire of 146 participants from small and medium-sized enterprises. The results highlight that perceived usefulness (PEU), low cost (LCOS), and compatibility (COM) had a significant positive impact on SMEs to adopt and use SMM. The facilitating conditions and perceived ease of use had a non-significant impact on the adoption and use of SMM by SMEs. This study also found that small enterprises have been affected by the factors more than medium-sized ones. Another finding is that enterprises that were forced to close were more significantly affected by the factors (Low Cost and Compatibility) than the non-closed ones during the first lockdown starting from March 2020. In the same context, Facilitating Conditions (FCO) was not significant as 63 % of the participated enterprises were closed during the lockdown and could not use their infrastructure

Sufficiency and Efficiency of Field Training for Radiology Students During Internship Experience in Najran University, Saudi Arabia

Purpose: The study was design to evaluate the effectiveness and adequacy of the internship period employing quantitative study descriptive survey approach.   Theoretical framework: Internship is requirement of every student of radiology program of Radiological Sciences patch for the award of bachelor's degree at Najran University, Saudi Arabia. The competency level would demonstrate influence the sufficiency and efficiency of clinical training during internship period which represent six months after completing nine levels of radiology program.   Design\Methodology\Approach: The survey was distributed to the tow levels of the last year of radiological sciences which composed of 81 male and female students which gathered seventy-seven (77) participants. Data collected through a questionnaire and summarized as percentages, frequencies, means and standard deviations using SPSS version 20.0.   Findings: The study revealed un adequacy of the internship period and showed low efficiency due to its short duration.   Research, Practical, Social Implication:The research construct and variables are identified the effectiveness and adequacy of the internship period.this  study will be the modele of internship with a new qualitative change related to a period of time acceptable to students, similar to other universities.   Originality/Value: The originality and value in this study are the framework conceptance and questionnaire that prepared and proved for evaluating the effectiveness and adequacy of the internship period for student of radiology program.   Conclusion: In general internship period must be efficient and adequate to enhance sufficiency and efficiency experience by intern trainees

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
