Developing a Secure and Trusted E-Voting System for Libyan Elections

Purpose: The aim of this study is to identify the issues and problems in the current Libyan voting system, and to develop a secure e-voting prototype system associated with the Libyan electoral system and the laws and legislation governing.   Theoretical framework: E-voting systems allow greater participation of eligible voters to cast their vote remotely or any location that the voter could be during election.   Design/methodology/approach: This study used mixed methodology. A qualitative method via interview would be used to collect qualitative data from citizens and election staff to determine functionalities and features of the proposed system. Using Semi-structured interviews with ten eligible voters, election officials. While a quantitative study conducted to evaluate users and elections of officials to determine how the systems fulfils the requirements and their expectations, to determine if the prototype proposed system offers practical solution to the Libyan voters and if the functionalities of the system fulfil the requirement gathered at the problem definition stage. The second prototype was regarded as meeting the key functional and non-functional requirement and ease of use criteria by users. After fixing the concerns found during the first prototype's evaluation in terms of the requirement criteria. The criterion for ease of use were met.   Findings: As a result, 87% of the evaluators indicated that they would adopt the system if it was introduced. Whereas 87% of the evaluators suggested that they would recommend the E-Voting system to their friends, colleagues, and Libyan Election Council.   Research, Practical & Social implications: Following the trial of the second prototype, the evaluators proposed that the Libyan E-Voting System (L-EVS) would assist them enable them to exercise their election rights.   Originality/value: Concerns and issues from previous political elections have spawned over numerous studies regarding voter confidentiality, voting security, and voting accuracy

Predicting Students’ Final Degree Classification Using an Extended Profile

The students’ progression and attainment gap are considered as key performance indicators of many universities worldwide. Therefore, universities invest significantly in resources to reduce the attainment gap between good and poor performing students. In this regard, various mathematical models have been utilised to predict students’ performances in the hope of informing the support team to intervene at an early stage of the at risk student’s at the university. In this work, we used a combination of institutional, academic, demographic, psychological and economic factors to predict students’ performances using a multi-layered neural network (NN) to classify students’ degrees into either a good or basic degree class. To our knowledge, the usage of such an extended profile is novel. A feed-forward network with 100 nodes in the hidden layer trained using Levenberg-Marquardt learning algorithm was able to achieve the best performance with an average classification accuracy of 83.7%, sensitivity of 77.37%, specificity of 85.16%, Positive Predictive Value of 94.04%, and Negative Predictive Value of 50.93%. The NN model was also compared against other classi?ers specifically k-Nearest Neighbour, Decision Tree and Support Vector Machine on the same dataset using the same features. The results indicate that the NN outperforms all other classi?ers in terms of overall classification accuracy and shows promise for the method to be used in Student Success ventures in the universities in an automatic manner

A family case of fertile human 45,X,psu dic(15;Y) males

We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal fragments to autosomes. These male patients are commonly infertile because of missing azoospermia factor regions from the Y long arm. In our familial case we found a pseudodicentric translocation chromosome, that contains almost the entire chromosomes 15 and Y. The translocation took place in an unknown male ancestor of our probands and has no apparent effect on fertility and phenotype of the carrier. FISH analysis demonstrated the deletion of the pseudoautosomal region 2 (PAR2) from the Y chromosome and the loss of the nucleolus organizing region (NOR) from chromosome 15. The formation of the psu dic(15;Y) chromosome is a reciprocal event to the formation of the satellited Y chromosome (Yqs). Statistically, the formation of 45,X,psu dic(15;Y) (p11.2;q12) is as likely as the formation of Yqs. Nevertheless, it has not been described yet. This can be explained by the dicentricity of this translocation chromosome that usually leads to mitotic instability and meiotic imbalances. A second event, a stable inactivation of one of the two centromeres is obligatory to enable the transmission of the translocation chromosome and thus a stably reduced chromosome number from father to every son in this family

Big Domains Are Novel Ca2+-Binding Modules: Evidences from Big Domains of Leptospira Immunoglobulin-Like (Lig) Proteins

binds to a Big domains, which would provide a novel functional role of the proteins containing Big fold. with dissociation constants of 2–4 µM. Lig A9 and Lig A10 domains fold well with moderate thermal stability, have β-sheet conformation and form homodimers. Fluorescence spectra of Big domains show a specific doublet (at 317 and 330 nm), probably due to Trp interaction with a Phe residue. Equilibrium unfolding of selected Big domains is similar and follows a two-state model, suggesting the similarity in their fold. binding

Task sensitivity in EEG biometric recognition

This work explores the sensitivity of electroencephalographic-based biometric recognition to the type of tasks required by subjects to perform while their brain activity is being recorded. A novel wavelet-based feature is used to extract identity information from a database of 109 subjects who performed four different motor movement/imagery tasks while their data was recorded. Training and test of the system was performed using a number of experimental protocols to establish if training with one type of task and tested with another would significantly affect the recognition performance. Also, experiments were conducted to evaluate the performance when a mixture of data from different tasks was used for training. The results suggest that performance is not significantly affected when there is a mismatch between training and test tasks. Furthermore, as the amount of data used for training is increased using a combination of data from several tasks, the performance can be improved. These results indicate that a more flexible approach may be incorporated in data collection for EEG-based biometric systems which could facilitate their deployment and improved performance

Effects of social approval bias on self-reported fruit and vegetable consumption: a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Self-reports of dietary intake in the context of nutrition intervention research can be biased by the tendency of respondents to answer consistent with expected norms (social approval bias). The objective of this study was to assess the potential influence of social approval bias on self-reports of fruit and vegetable intake obtained using both food frequency questionnaire (FFQ) and 24-hour recall methods.</p> <p>Methods</p> <p>A randomized blinded trial compared reported fruit and vegetable intake among subjects exposed to a potentially biasing prompt to that from control subjects. Subjects included 163 women residing in Colorado between 35 and 65 years of age who were randomly selected and recruited by telephone to complete what they were told would be a future telephone survey about health. Randomly half of the subjects then received a letter prior to the interview describing this as a study of fruit and vegetable intake. The letter included a brief statement of the benefits of fruits and vegetables, a 5-A-Day sticker, and a 5-a-Day refrigerator magnet. The remainder received the same letter, but describing the study purpose only as a more general nutrition survey, with neither the fruit and vegetable message nor the 5-A-Day materials. Subjects were then interviewed on the telephone within 10 days following the letters using an eight-item FFQ and a limited 24-hour recall to estimate fruit and vegetable intake. All interviewers were blinded to the treatment condition.</p> <p>Results</p> <p>By the FFQ method, subjects who viewed the potentially biasing prompts reported consuming more fruits and vegetables than did control subjects (5.2 vs. 3.7 servings per day, p < 0.001). By the 24-hour recall method, 61% of the intervention group but only 32% of the control reported eating fruits and vegetables on 3 or more occasions the prior day (p = 0.002). These associations were independent of age, race/ethnicity, education level, self-perceived health status, and time since last medical check-up.</p> <p>Conclusion</p> <p>Self-reports of fruit and vegetable intake using either a food frequency questionnaire or a limited 24-hour recall are both susceptible to substantial social approval bias. Valid assessments of intervention effects in nutritional intervention trials may require objective measures of dietary change.</p
