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.     

An effectiveness‐based evaluation of five state pre‐kindergarten programs

Since 1980, the number of state pre‐kindergarten (pre‐K) programs has more than doubled, with 38 states enrolling more than one million children in 2006 alone. This study evaluates how five state pre‐K programs affected children's receptive vocabulary, math, and print awareness skills. Taking advantage of states' strict enrollment policies determined by a child's date of birth, a regression‐discontinuity design was used to estimate effects in Michigan, New Jersey, Oklahoma, South Carolina, and West Virginia. For receptive vocabulary, only New Jersey and Oklahoma yielded significant standardized impacts, though two of the three other coefficients were in a direction indicating positive effects. For math, all the coefficients were positive but only Michigan and New Jersey yielded reliable results. The largest impacts were for print awareness, where all five coefficients were positive and four were reliable in Michigan, New Jersey, South Carolina, and West Virginia. The five states were not randomly selected and, on average, have higher quality program standards than non‐studied states, precluding formal extrapolation to the nation at large. However, our sample of states differed in many other ways, permitting the conclusion that state pre‐K programs can have positive effects on children's cognitive skills, though the magnitude of these effects varies by state and outcome. © 2008 by the Association for Public Policy Analysis and Management.     

Reforming Social Services in Hong Kong: The Role of Contracting and Performance Management in the Non‐Profit Sector

Contracts and performance management, along with the concept of consumerism, have become the fundamental metaphors for New Public Management (NPM) and key changes in the public service. ‘Doing well while doing good’ and finding generally acceptable accountability measures for social services have become the perennial aspirations of planners, service providers and funders. This article examines the contingent factors and rationales behind the quality movement and recontracting exercise in reforming the delivery of personal social service programs in Hong Kong within the framework of New Public Management (NPM). It explains the use of long‐term relational contracts rather than the standard business contracts between the government as funder and non‐profit organisations as service providers. It also deals with the complex relationships among quality issues, quality standards, consumerism, accountability, performance indicators, and performance management.     

Reactions of potential jurors to a hypothetical malpractice suit: alleging failure to perform a prostate-specific antigen test

We conducted focus groups with 47 potential jurors who were presented with different scenarios in a hypothetical malpractice case involving failure to order a PSA test. Better documentation that a patient made an informed decision to decline a PSA test appeared to provide more medical-legal protection for physicians, especially with the use of a decision aid.
