A 21‐Locus Autosomal SNP Multiplex and its Application in Forensic Science

To develop a cost‐effective technique for single‐nucleotide polymorphism (SNP) genotyping and improve the efficiency to analyze degraded DNA, we have established a novel multiplex system including 21‐locus autosomal SNPs and amelogenin locus, which was based on allele‐specific amplification (ASA) and universal reporter primers (URP). The target amplicons for each of the 21 SNPs arranged from 63 base pair (bp) to 192 bp. The system was tested in 539 samples from three ethnic groups (Han, Mongolian, and Zhuang population) in China, and the total power of discrimination (TPD) and cumulative probability of exclusion (CPE) were more than 0.99999999 and 0.98, respectively. The system was further validated with forensic samples and full profiles could be achieved from degraded DNA and 63 case‐type samples. In summary, the multiplex system offers an effective technique for individual identification of forensic samples and is much more efficient in the analysis of degraded DNA compared with standard STR typing.

The EU approach to net neutrality: Network operators and over-the-top players,friends or foes?

This paper will mainly focus on the EU approach to net neutrality, notably the adequacy of existing and future EU rules to tackle the issue and the ongoing policy debate. It will also consider whether the market has effectively worked around the regulatory lacunae by looking into the relationships between the telecoms industry, as a regulated sector, and the over-the-top (OTT) players. In this regard, it will explore to what extent there is a real battle between telcos and OTTs or if both parties are already finding their own ways to overcome their (apparent) disputes.     

浅谈电视节目模式的著作权保护

随着互联网的发展和观众需求的日益多样化,全球范围内的电视节目模式许可交易日益增长,同时也产生了诸多法律纠纷,而电视节目模式的法律保护仍然存在立法空白。结合欧美法院判例和学术界的观点,本文对中美电视节目模式的法律保护现状、电视节目模式的侵权认定以及在现阶段如何对电视节目模式进行法律保护作出了初步探讨,得出结论是未来趋势应将电视节目模式作为汇编作品予以著作权法的保护,这也是建设社会主义文化强国,增强国家文化软实力的必要举措。     

The High Representative and directoires in European foreign policy: the case of the nuclear negotiations with Iran

ABSTRACT

The negotiations with Iran about its nuclear programme have seen the most protracted involvement of the High Representatives of the European Union in a high-profile policy case. This article traces the evolution of the High Representatives’ participation in the negotiations, from the first contacts with the E3 (Germany, France and the United Kingdom) in 2003 to the adoption of the Joint Comprehensive Plan of Action in 2015. It focuses on the institutional role the High Representatives played in relation with the directoires leading the talks with Iran – first the E3 and, since 2006, E3/EU. In this context, it examines the personal and organisational factors that affected the influence each of the three High Representatives (Javier Solana, Catherine Ashton and Federica Mogherini) had in regard to the directoires. The analysis distinguishes specifically between the phases before and after the 2009 Lisbon Treaty. The article shows how similar personal qualities of the three High Representatives in terms of problem-solving and trust-building gave them political capital that enabled them to adopt a fairly constant role as bridge-builders within the directoires and between the directoires and other actors. The reforms of the Lisbon Treaty had only a minor impact.     

Chick lit politics in a post-truth era: tricksters,blessees and postfeminist girlpower in Angela Makholwa’s The Blessed Girl

The possibility of an emancipated politics in chick lit novels remains a contested question among postfeminist critics. Drawing on definitions of postfeminism as a transnational sensibility, this article examines South African chick lit in relation to what has been termed post-truth or trickster politics in the context of the rise of politicians, such as Donald Trump. I read Angela Makholwa’s novel The Blessed Girl as an example of African chick lit that features a blessee narrator, a young woman who lives a luxurious lifestyle financed by older men, who is deeply influenced by a Trumpian mode of self-making. By employing a trickster aesthetic and narrative strategies, such as unreliable narration and reader address, the novel, I argue, however also unsettles established parameters of neoliberal girlpower, moving beyond its assumed anti-politicalness, as well as a simple understanding of the blessee figure through either a lens of victimhood or amorality.     

Organic impurity profiling of fentanyl samples associated with recent clandestine laboratory methods

Nearly a decade ago, fentanyl reappeared in the United States illicit drug market. In the years since, overdose deaths have continued to rise as well as the amount of fentanyl seized by law enforcement agencies. Research surrounding fentanyl production has been beneficial to regulatory actions and understanding illicit fentanyl production. In 2017, the Drug Enforcement Administration (DEA) began collecting seized fentanyl samples from throughout the United States to track purity, adulteration trends, and synthetic impurity profiles for intelligence purposes. The appearance of a specific organic impurity, phenethyl-4-anilino-N-phenethylpiperidine (phenethyl-4-ANPP) indicates a shift in fentanyl production from the traditional Siegfried and Janssen routes to the Gupta-patent route. Through a collaboration between the DEA and the US Army's Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC), the synthesis of fentanyl was investigated via six synthetic routes, and the impurity profiles were compared to those of seized samples. The synthetic impurity phenethyl-4-ANPP was reliably observed in the Gupta-patent route published in 2013, and its structure was confirmed through isolation and structure elucidation. Organic impurity profiling results for illicit fentanyl samples seized in late 2021 have indicated yet another change in processing with the appearance of the impurity ethyl-4-anilino-N-phenethylpiperidine (ethyl-4-ANPP). Through altering reagents traditionally used in the Gupta-patent route, the formation of this impurity was determined to occur through a modification of the route as originally described in the Gupta patent.     

Alternatives to EU Membership and the Rational Imagination

The domestic scenario following a Brexit vote is likely to be characterised by high stakes, uncertainty and fissile political debate. No off‐the‐peg arrangement touted for Brexit—be it Norwegian, Swiss, Turkish or Canadian—was designed to engage with such a context. Nor does it seem wise to rush to medium‐term commitments which might pre‐empt democratic politics and wise choices. Far more important will be the legitimacy of any institutional settlement governing this arrangement, which will provide the context for its revision and development and the space for democratic reflection over how these policies are to be governed. It will be suggested that here there is much insight to be gained from looking at regional arrangements beyond the EU.
