Identifying Fatal Head Injuries on Postmortem Computed Tomography Using Convolutional Neural Network/Deep Learning: A Feasibility Study

Postmortem computed tomography (PMCT) is a relatively recent advancement in forensic pathology practice that has been increasingly used as an ancillary investigation and screening tool. One area of clinical CT imaging that has garnered a lot of research interest recently is the area of “artificial intelligence” (AI), such as in screening and computer-assisted diagnostics. This feasibility study investigated the application of convolutional neural network, a form of deep learning AI, to PMCT head imaging in differentiating fatal head injury from controls. PMCT images of a transverse section of the head at the level of the frontal sinus from 25 cases of fatal head injury were combined with 25 nonhead-injury controls and divided into training and testing datasets. A convolutional neural network was constructed using Keras and was trained against the training data before being assessed against the testing dataset. The results of this study demonstrated an accuracy of between 70% and 92.5%, with difficulties in recognizing subarachnoid hemorrhage and in distinguishing congested vessels and prominent falx from head injury. These results are promising for potential applications as a screening tool or in computer-assisted diagnostics in the future.

An Afrocentric exploration of Jacob Zuma's anti Apartheid stance: The question of Israeli–Palestinian struggle

In this article, the author utilizes interdisciplinary critical discourse analysis to analyse the state of South Africa–Israel relations under the Zuma‐led African National Congress (ANC). The author ground roots this article on Afrocentricity as the alternative theoretical framework to identify the position of the ANC in relation to the unfolding events in Israel and broadly analyse this position in order to make sense of it. This is done within the context of the Zuma‐led ANC in order to tease out major contradictions, which characterizes the administration of Zuma's stance on attested Apartheid Israel. The central question engaged with in this article is to determine whether political and ideological counterstatements to those the ANC communicated, by some of the opposition political parties such as African Christian Democratic Party (ACDP), had any major implications on South Africa's foreign policy on the Apartheid Israel. In this article, the author argues extensively that Zuma's foreign policy on Israel can best be understood when located into his entire term as president of South Africa and the NASREC resolution of 2017.     

An Afrocentric critique of China's security concerns in Africa: The cases of Mali and South Sudan

China's security concerns in Africa has recently become a subject of much academic debate. Most of the academic studies on this subject have wrongly assumed a continental standpoint, which does not take into contemplation the distinctive national captivates of China toward each distinctive African State. Such analytic discourse analysis were also heavily subjected to North [ern] angled perspectives as expressed in either liberal or realist contextual lens, views, and critics. Despite this, the Scholarly discourse on the security concerns of China towards Mali and South Sudan have not been proportionately apprehended. Based on the alternative Afrocentric perspective, this article seeks to employ Mali and South Sudan as test cases to critique the Security Concerns of China toward Mali and South Sudan. The central argument of this article is that, China's Security Concerns towards Mali and South Sudan can best be understood when located within the context of mineral resources complex. Methodologically, this article is based on document review and interdisciplinary discourse analysis in their comprehensive form.     

A Quarter Century of Participation in School-Based Extracurricular Activities: Inequalities by Race,Class, Gender and Age?

Extracurricular activity participation is linked to positive development, but it is also a setting for inequality. Using a quarter century of data from Monitoring the Future (N?=?593,979; 51% female; 65% non-Hispanic white; 13% non-Hispanic black; 12% Hispanic; 4% non-Hispanic Asian/Pacific Islander; 7% other race), this article documents patterns and trends in school-based extracurricular participation by race, social class, gender, and age, and their links to academic and substance use outcomes. Findings reveal differences by race and confirm a division by social class that has worsened over time. Further, girls are gaining on boys and surpass them in some types of school-based activities. Participation is linked to better academic outcomes and less substance use, affirming the importance of redressing the inequalities revealed.
