英美辅警体系研究：比较与借鉴

国内学术界对英美国家的辅警研究有一种泛化倾向,把一些本不属于辅警体系的治安力量纳入其中。事实上,在英国,辅警包括Special Constable和Police Community Support Officer两种,而在美国,辅警指的是Auxiliary Police。目前,我国并没有真正的辅警体系,而警力的严重不足又使基层公安机关离不开辅警的支持,可以借鉴英关模式建立我国的辅警体系,包括治安辅警和交通辅警两种类型。     

Breaking with tradition? South Africa–UK relations

Just over twenty years into its new era of democracy, South African foreign policy appears to be undergoing important changes in orientation and global positioning. Indeed, post-apartheid South African foreign policy has been steadily shifting away from a preoccupation with more traditional partnerships to developing alliances and coalitions with emerging economies and actors seeking to reform the global governance order. The paper seeks to understand the implications of this shift for South Africa's relationship with its most pivotal and enduring traditional ‘partner' – the United Kingdom. Thus, the paper proposes that this relationship can be best understood by considering it on different and at least partially contradictory levels, reflecting South Africa's own ambiguous identity as an emerging middle power.     

Under the radar: policing non-violent domestic abuse in the US and UK

Physical violence is but one of many tools that may be used to gain greater power within intimate relationships, yet the legal response has been critiqued for failing to recognise and respond to the full spectrum of abusive behaviours, such as coercive control. Using a sample of police officers from the United States (US) and the United Kingdom (UK), the current study utilises hypothetical vignettes to assess police officers’ perceptions of domestic abuse, including those incidents that are not necessarily physically violent, but involve stalking and other coercive, controlling behaviours that are harmful and require intervention. Within- and between-country similarities and differences were analysed. Findings revealed that the majority of officers in both countries possessed a good level of understanding of domestic abuse and how they should respond to it – amidst and beyond the physical violence. However, our analysis of both quantitative and qualitative data also showed that the use of physical violence is at the forefront of many officers’ expectations about domestic abuse, and that when physical violence is absent, the police response is less proactive. Our study finds some support for the idea that non-physical abuse does go “under the radar” to some extent for some officers, and that this is more the case for American officers than their British counterparts. Findings are discussed in terms of context of the research sites and implications for policy, practice and future research.     

Avoiding the internet of insecure industrial things

Security incidents such as targeted distributed denial of service (DDoS) attacks on power grids and hacking of factory industrial control systems (ICS) are on the increase. This paper unpacks where emerging security risks lie for the industrial internet of things, drawing on both technical and regulatory perspectives. Legal changes are being ushered by the European Union (EU) Network and Information Security (NIS) Directive 2016 and the General Data Protection Regulation 2016 (GDPR) (both to be enforced from May 2018). We use the case study of the emergent smart energy supply chain to frame, scope out and consolidate the breadth of security concerns at play, and the regulatory responses. We argue the industrial IoT brings four security concerns to the fore, namely: appreciating the shift from offline to online infrastructure; managing temporal dimensions of security; addressing the implementation gap for best practice; and engaging with infrastructural complexity. Our goal is to surface risks and foster dialogue to avoid the emergence of an Internet of Insecure Industrial Things.     

Background levels of body fluids and DNA on the shaft of the penis and associated underpants in the absence of sexual activity

This study examines the background of blood, saliva, semen and autosomal DNA on penile swabs and underpants from males in the absence of recent sexual activity. Based on the data collected by the AFSP Body Fluid Forum, the results of this study show that; there is a very low expectation of detecting blood on penile swabs and male underpants; a low expectation of detecting saliva on penile swabs and male underpants; and spermatozoa would be expected in less than a quarter of penile swabs and three quarters of male underpants. As none of the samples had detectable levels of DNA which were suitable for meaningful comparison that did not match the donor or their partner, the expectation of detecting a DNA profile from the cellular background on penile swabs or underpants from a male who has not been involved in recent sexual intercourse is very low. The results of this study are extremely informative when evaluating the significance of blood, saliva, semen and DNA detected on the penile swabs and underpants of males in cases of alleged sexual assault.     

Assessing the background levels of body fluids on hands

Forensic scientists are often asked to assist the court by evaluating the significance of finding body fluids on the hands of an individual; however, there is an absence of published data regarding the background levels of body fluids on hands. Whilst the scientist can use casework experience to inform the courts on the significance of the results, it would be advantageous to have data which could assist with this interpretation. This study was designed to ascertain the background levels of blood, semen, saliva, hairs/fibres and staining/debris on hands in the general population by sampling from delegates attending a scientific conference.The findings suggest that approximately one third of the population would be expected to have hairs or fibres on their hands and that females are more likely to have visible staining on their hands than males. Presumptive tests for blood and semen yielded negative results in all samples; however, almost 2 % of the samples were found to contain a very low number of sperm heads. In contrast, the majority of samples tested positive for the presence of saliva using the presumptive Phadebas® amylase test. The data supports the caution applied by forensic practitioners when evaluating the presence of saliva detected using the presumptive Phadebas® amylase test based on the lack of specificity and indicates that the RSID™-Saliva test would be more suitable to use.
