The planning and control of operations involving the use of lethal force

This is an analysis of the case law of the European Court of Human Rights on the obligation on States to plan and control the use of potentially lethal force by their police and military personnel. It illustrates the Court's attachment to the strict or careful scrutiny test and suggests how the Court might want to develop its jurisprudence in the future.

Property and Emotions

Relatively little has been written on the connection between property and emotions from a legal perspective, despite the centrality of property in everyday life and the complex relationships that exist between owners and their property. Scholars working in other disciplines have analyzed these links, identifying ‘proprietary’ emotions and corresponding emotional traits. However, little has been mapped onto the field of law. This paper looks at key emotions surrounding property as identified in psychological and, to a lesser extent, sociological literature. After mapping these onto selected areas of property law, it posits the need for a deeper and more collective field of inquiry.

Negotiating Territoriality and Diversity: Young People’s Encounters in Northern Ireland Divided Communities

Neighborhoods across the globe are becoming increasingly ‘divers’, yet we still find their urban encounters reproduced through negotiating differences that escalates moods of social inequality and spatial imbalances. Research on ethnic division also stresses the spatial aspects of their production as shared urban spaces are mostly signified in the literature as ethnic ‘enclaves’. Territoriality and place attachment, in this sense, has a wide impact on the people’s everyday encounters while experiencing segregation. These historical narratives have produced communities that exhibit high levels of intracommunity relations and localized networking. This article investigates how youngster generations in Northern Ireland perceive, accept and respond to their differences, or perhaps how they act against it, to push the boundaries towards more diversity. In fact, the spatial and temporal encounters that occur among one community and the ‘Other’ signify a sort of negotiations and being more constructive about the future. The argument maintains that territoriality and place attachment has a wide impact on the young people’s everyday experiences. The empirical study shows how individuals and community groups position and identify themselves under the impact of social segregation. Building on social identity theories, I explain how people in Derry have established their own sense of belonging, of who they are, based on their group memberships which eventually became an important source of pride and self-esteem.

A comparison of gold nanoparticle surface co-functionalization approaches using Polyethylene Glycol (PEG) and the effect on stability, non-specific protein adsorption and internalization

To create clinically useful gold nanoparticle (AuNP) based cancer therapeutics it is necessary to co-functionalize the AuNP surface with a range of moieties; e.g. Polyethylene Glycol (PEG), peptides and drugs. AuNPs can be functionalized by creating either a mixed monolayer by attaching all the moieties directly to the surface using thiol chemistry, or by binding groups to the surface by means of a bifunctional polyethylene glycol (PEG) linker. The linker methodology has the potential to enhance bioavailability and the amount of functional agent that can be attached. While there is a large body of published work using both surface arrangements independently, the impact of attachment methodology on stability, non-specific protein adsorption and cellular uptake is not well understood, with no published studies directly comparing the two most frequently employed approaches. This paper compares the two methodologies by synthesizing and characterizing PEG and Receptor Mediated Endocytosis (RME) peptide co-functionalized AuNPs prepared using both the mixed monolayer and linker approaches. Successful attachment of both PEG and RME peptide using the two methods was confirmed using Dynamic Light Scattering, Fourier Transform Infrared Spectroscopy and gel electrophoresis. It was observed that while the 'as synthesized' citrate capped AuNPs agglomerated under physiological salt conditions, all the mixed monolayer and PEG linker capped samples remained stable at 1M NaCl, and were stable in PBS over extended periods. While it was noted that both functionalization methods inhibited non-specific protein attachment, the mixed monolayer samples did show some changes in gel electrophoresis migration profile after incubation with fetal calf serum. PEG renders the AuNP stable in-vivo however, studies with MDA-MB-231 and MCF 10A cell lines indicated that functionalization with PEG, blocks cellular uptake. It was observed that co-functionalization with RME peptide using both the mixed monolayer and PEG linker methods greatly enhanced cellular internalization compared to PEG capped AuNPs.

Substance Use and Misuse : Adolescent Substance Use in the context of the family ; a qualitative study of young people's views on parent child attachments , parenting style and parental substance use

Introduction and Aims. While the role of the family in adolescent substance use has been well documented, few studies have attempted to explore in-depth youth perceptions of how these familial processes/dynamics influence teenage substance use. This paper reports the findings from a study exploring risk and protective factors for teenage substance use within the context of the family as perceived by young people with a view to informing current and future family based prevention and education interventions.
Design and Methods. Data collection took place in nine post-primary schools across Northern Ireland. Nine focus groups using participatory techniques were facilitated with a purposive sample of sixty-two young people (age 13-17 years). Data were transcribed verbatim and analysed using a content/thematic analysis.
Results. Three broad themes/aspects of the family emerged from the data, which may serve to protect or attenuate the risk of substance use among young people. Parent-child attachment was a major theme identified in protecting adolescents from substance use in addition to effective parenting particularly an authoritative style of parenting supplemented by parental monitoring and good parent-child communication to encourage child disclosure. Family substance use was deemed to impact on children’s substance use if exposed at an early age and the harms associated with PSM were discussed in detail.
Discussion and Conclusions. The qualitative approach provides insight into current understanding of youth perceptions of substance use in the context of family dynamics. A number of recommendations are outlined. Family based (preventive) interventions/parenting programmes may benefit from components on effective parenting including authoritative styles, parental monitoring, effective communication, spending time together (building attachments), parent-child conflict, adolescent development and factors which impact on parenting. Parenting programmes tailored to mothers and fathers may be beneficial. School based interventions targeting children/adolescents may be best placed to target children living with parental substance misuse.
