IoT forensics: Exploiting log records from the DAHUA technology CCTV systems

CCTV surveillance systems are ubiquitous IoT appliances. Their forensic examination has proven critical for investigating crimes. DAHUA Technology is a well-known manufacturer of such products. Despite its global market share, research regarding digital forensics of DAHUA Technology CCTV systems is scarce and currently limited to extracting their video footage, overlooking the potential presence of valuable artifacts within their log records. These pieces of evidence remain unexploited by major commercial forensic software, yet they can hide vital information for an investigation. For instance, these log records document user actions, such as formatting the CCTV system's hard drive or disabling camera recording. This information can assist in attributing nefarious actions to specific users and hence can be invaluable for understanding the sequence of events related to incidents. Therefore, in this paper, several DAHUA Technology CCTV systems are thoroughly analyzed for these unexplored pieces of evidence, and their forensic value is presented.

Radiographic age estimation based on degenerative changes of vertebrae

Age estimation is an important component of decedent identification. When assessing adult remains, anthropologists frequently use gross examination of skeletal elements, such as clavicles, ribs, and pubic symphyses. For fleshed bodies, this requires the removal of these elements and maceration prior to analysis. A new method was developed using radiographic imaging to estimate age from degenerative changes of the lower thoracic and upper lumbar vertebrae. This technique will complement anthropological age estimation methods in young and middle-aged adults and may serve as a stand-alone method for older individuals. Digital radiographs from 240 medical examiner cases were evaluated. The sample included 120 females and 120 males between the ages of 18 and 101 years. A 3-phased scoring system was used for the target vertebrae. Transition analysis was conducted on binned average scores and a Bayesian approach was used to assign age intervals. At the 90% credible interval, individuals in Bin 1 were under 36 years of age while those in Bin 3 were over 47 years of age. Individuals in Bin 2 showed too much age variation to be informative. No significant differences were found between males and females. These findings will be especially useful in the age estimation of older adults and may eliminate the need for skeletal sampling in medicolegal cases where advanced degenerative changes are radiographically observed in the lower thoracic and/or upper lumbar vertebrae. This method was developed for use on fleshed individuals but may also be applicable to skeletonized remains.     

China's provincial diplomacy to Africa: applications to health cooperation

There is a prevailing view of China as a unitary actor in its relationships with African countries. This view is incomplete: on the contrary, China is a collection of provinces, autonomous regions and municipalities with myriad strategic ties to African countries, with decentralization shaping the current form of Chinese government and its level of efficiency. In this paper, factors have been explored for why Chinese provinces have played a role in foreign cooperation in health of African countries, in addition to trade and foreign direct investment. Incentives and disincentives for Chinese provinces to engage internationally in foreign cooperation and health assistance have been identified. The concept of paradiplomacy for health has been presented and this typology has been applied to the example of Chinese medical teams. Finally, we draw linkages between China and other members of Brazil, Russia, India, China, and South Africa.     

Support forMiranda among police chiefs: A qualitative examination

The U.S. Supreme Court recently grappled with the question of whether it should overturn the landmark case of Miranda v. Arizona. Abolitionists argued the warnings handcuffed the police and allowed many criminals to go free. Proponents maintained Miranda protected offenders and engendered a certain level of professionalism among police officers. Before the Court decided to uphold Miranda, 95 police chiefs from the Commonwealth of Virginia were surveyed about their perceptions concerning Miranda. While one could categorize many chiefs as conformists who wished to keep the warnings, a significant proportion were innovators who advocated various changes. Reasons for these beliefs and their implications are discussed.
