The majority of noma patients surviving with aesthetical effects are exposed to stigmatization and social rejection. Studies focusing on the socio-psychological impact of noma survivors have rarely been done. Our study aimed to identify the differences in social acceptance/rejection and the influencing factors associated with social acceptance in noma patients. Methods: A cross-sectional study was conducted at the NGO-Sentinelles (Niger) reception center on patients with noma from Zinder, Maradi, and Tahoua regions between 9<sup>th</sup> May 2017 and 2<sup>nd</sup> June 2017. The survey was conducted through a face-to-face interview on patients admitted to the center and those discharged from the centre after the treatment. The interview questionnaire comprised 45 questions (Cronbach’s alpha coefficient = 0.812) with pathological information, sociodemographic characteristics, and socio-psychological qualitative information. Findings: We recorded 50 noma patients (43 from Zinder and 7 from Maradi and Tahoua). The younger patients (1 - 5 years old), noma patients who stayed in school during follow-up treatment, patients who were referred by a health structure, patients enrolled into the centre in a short time (<30 days), and patients in the acute phase of noma had a significantly high social acceptance rate with 60.0%, 82.9%, 60.0%, 57.1% and 94.3% respectively;whereas single adults and cheek lesion site had the highest social rejection rate when compared to their corresponding factors with 60.0% and 86.7% respectively. There were significant differences in victims’ perception of noma [χ<sup>2</sup> = 45.536, (P < 0.001)] and acceptance of their new faces [P = 0.023], between the social acceptance and social rejection rate, therefore all patients who accepted their new faces felt social acceptance. Social acceptance was significantly highly correlated with pathological history (admission method, phase of noma, care, and treatment received at center) with r<sub>s</sub> ranging from 0.609 to 0.810, moderately correlated with patient’s sociodemographic characteristics (age, marital status, and region) with r<sub>s</sub> ranging from 0.381 to 0.474. Lowly correlated with clinical evolution after treatment (r<sub>s</sub> = 0.293). Logistic regression results showed that the likelihood of social acceptance increased when the patient’s age was young (≤15 years), their marital status was minor, they were enrolled at the school before noma appearance, they were referred to the centre after diagnosis, the admission time to the centre was short (≤30 days), acute phase of noma, and care received at the centre was non-surgery. The location of the lesion on the cheek was a risk factor for social acceptance, indicating cheek lesions from noma increased the likelihood of social rejection in our study. Conclusion: The sociodemographic characteristics, pathological history, and psychological aspects of noma patients were correlated and were found to be important factors influencing their social acceptance/rejection rate.展开更多

Moreover, information such as academic data, research data, personal data, proprietary knowledge, complex equipment designs and blueprints for yet to be patented products has all become extremely susceptible to Cybersecurity attacks. This research will investigate factors that affect that may have an influence on perceived ease of use of Cybersecurity, the influence of perceived ease of use on the attitude towards using Cybersecurity, the influence of attitude towards using Cybersecurity on the actual use of Cybersecurity and the influences of job positions on perceived ease of use of Cybersecurity and on the attitude towards using Cybersecurity and on the actual use of Cybersecurity. A model was constructed to investigate eight hypotheses that are related to the investigation. An online questionnaire was constructed to collect data and results showed that hypotheses 1 to 7 influence were significant. However, hypothesis 8 turned out to be insignificant and no influence was found between job positions and the actual use of Cybersecurity.展开更多

In addition, as an alternative approach, the griddy Gibbs sampler is proposed by [1] and utilized by [2]. This paper proposes an acceptance-rejection Metropolis-Hastings algorithm as a third approach, and compares these three algorithms through Monte Carlo experiments. The experimental results show that the griddy Gibbs sampler is the most efficient algorithm among the algorithms whether the number of observations is small or not in terms of the computation time and the inefficiency factors. Moreover, it seems to work well when the size of grid is 100.展开更多
