Valour for Money? Contested Commodification in the Market for Security
Scholars of security governance generally assume that the labour of private security officers can straightforwardly be transformed into discrete commodities. We argue, by contrast, that it is extremely difficult to commodify the labour of private security officers because their duties frequently require them to confront and work through both economic responsibilities (what does my contract say?) and moral obligations (what does my conscience say?). We substantiate this argument by exploring how heroic acts performed by private security officersâsuch as preventing suicide attempts, intervening in violent assaults and orchestrating hazardous evacuationsâare celebrated through industry awards ceremonies. In so doing, we not only contribute towards the conceptualization of security goods as contested commodities but also facilitate a reappraisal of the market for security
Green consumer markets in the fight against climate change
Climate change has become one of the greatest threats to environmental security, as attested by the growing frequency of severe flooding and storms, extreme temperatures and droughts. Accordingly, the European Unionâs (EU) 6th Environment Action Programme (2010) lists tackling climate change as its first priority. A key aim of the EU has been to cut CO2 emissions, a major factor in climate change, by 8% until 2012 and 20% until 2020. The European Commission has proposed the encouragement of private consumer market for green products and services as one of several solutions to this problem. However, existing research suggests that the market share of these products has been only 3%, although 30% of individuals favour environmental and ethical goods. This article uses Public Goods Theory to explain why the contribution of the green consumer market to fighting climate change has been and possibly may remain limited without further public intervention
On the purification of α-cellulose from resinous wood for stable isotope (H, C and O) analysis
α-Cellulose was isolated from four samples of Scots pine (Pinus sylvestris L.). Each sample was divided into two portions. One portion had the resins removed by solvent extraction prior to removal of lignins by treatment with acidic sodium chlorite solution and treatment with sodium hydroxide solution to remove hemicelluloses. The other portion was processed in the same way apart from the solvent extraction step. The isolated wood constituents were characterised by attenuated total reflectance Fourier transform infrared (ATR/FT-IR) spectroscopy. The infrared spectra of the resulting α-cellulose samples were identical indicating that treatment with acidic sodium chlorite and sodium hydroxide was sufficient to remove resins. The values of the stable isotope ratios (carbon, oxygen and hydrogen) for each pair of α-cellulose sub-samples also showed no significant differences within the reproducibility of the methods. The implication of these studies demonstrate that the customary step of resin extraction from pine is unnecessary if sodium chlorite and sodium hydroxide are used for the isolation of α-cellulose following the technique described in this paper. In addition, the study demonstrates that the oxygen isotope ratio of the water used for cellulose extraction does not influence the stable isotope values in the α-cellulose obtained. The importance of isotopic homogeneity within the cellulose sample is also highlighted
Special focus: Selected developments in the area of children deprived of liberty
This volume of the Global Campus Human Rights Journal consists of three parts. The first part is a âSpecial focus: Selected developments in the area of childrenâs rightsâ. This is the second occasion on which the Journal devotes special attention to the rights of children. The special focus is a product of this collaboration between the Global Campus of Human Rights and the Right Livelihood Foundation. In 2019 a cooperation agreement was signed between the Global Campus of Human Rights and the Right Livelihood Foundation. Its purpose is to âpromote the acknowledgment and observance of human and child rights and to strengthen the participation of children in all matters affecting their lives in the present and in the futureâ. The Right Livelihood Foundation is a Swedish charity organisation, the mission of which is to honour and support courageous people solving global problems. The Foundation is a politically-independent and nonideological platform for the voices of its Laureates to be heard. The articles in this part are linked to the UN Global Study on Children Deprived of Liberty (2019). In 2020 the âGlobal Classroom 2020â, which was presented virtually due to the COVID-19 pandemic, focused on the UN Global Study on Children Deprived of Liberty and the implementation of its recommendations. These Global Classrooms, a feature of the Global Campus since 2013, brings together students and professors from all regional hubs for a week-long conference where a topic of common interest is studied, analysed and discussed. The Global Classroom facilitates interaction among students from the different regional programmes by ii (2020) 4 Global Campus Human Rights Journal organising dedicated activities and providing a forum for discussion and networking. The articles in this part of the Journal are all products of collaboration between students and staff working with each of the regional Masterâs programmes within the framework of the collaboration between the Global Campus of Human Rights and the Right Livelihood Foundation
A small temperature rise may contribute towards the apparent induction by microwaves of heatshock gene expression in the nematode Caenorhabditis elegans
We have previously reported that low-intensity microwave exposure (0.75-1.0 GHz CW at 0.5 W; SAR 4-40 mW kg-1) can induce an apparently non-thermal heat-shock response in Caenorhabditis elegans worms carrying hsp16-1::reporter genes. Using matched copper TEM cells for both sham and exposed groups, we can detect only modest reporter induction in the latter (15-20% after 2.5 h at 26°C, rising to ~50% after 20 h). Traceable calibration of our copper TEM cell by the National Physical Laboratory (NPL) reveals significant power loss within the cell (8.5% at 1.0 GHz), accompanied by slight heating of exposed samples (~0.3°C at 1.0 W). Thus exposed samples are in fact slightly warmer (by â€0.2°C at 0.5 W) than sham controls. Following NPL recommendations, our TEM cell design was modified with the
aim of reducing both power loss and consequent heating. In the modified silver-plated cell, power loss is
only 1.5% at 1.0 GHz, and sample warming is reduced to ~ 0.15°C at 1.0 W (i.e. †0.1°C at 0.5 W). Under sham:sham conditions, there is no difference in reporter expression between the modified silverplated TEM cell and an unmodified copper cell. However, worms exposed to microwaves (1.0 GHz and 0.5 W) in the silver-plated cell also show no detectable induction of reporter expression relative to sham controls in the copper cell. Thus the 20% âmicrowave inductionâ observed using two copper cells may be
caused by a small temperature difference between sham and exposed conditions. In worms incubated for 2.5 h at 26.0, 26.2 and 27.0°C (with no microwave field), there is a consistent and significant increase in reporter expression between 26.0 and 26.2°C (by ~20% in each of 6 independent runs), but paradoxically expression levels at 27.0°C are similar to those seen at 26.0°C. This surprising result is in line with other evidence pointing towards complex regulation of hsp16-1 gene expression across the sub-heat-shock range of 25-27.5°C in C. elegans. We conclude that our original interpretation of a non-thermal effect of microwaves cannot be sustained; at least part of the explanation appears to be thermal
Plural policing in Europe:relationships and governance in contemporary security system
References to âplural policingâ, âpolicing beyond the policeâ and the âextended policing familyâ are now commonplace in many discussions of policing in late modern societies. There is a danger that claims about the dynamic and changing nature of plural policing themselves become a new orthodoxy and begin to lose a sense of local nuance and recognition of the importance of place-based specificity and context in understanding the particularities of policing. It is this need to unpack the complex ways in which contemporary plural policing is now configured at a local level within different national political environments that provides the underpinning rationale for this Special Issue. Focussing on aspects of relationships and governance in six jurisdictions across northern and western Europe, it provides important insights into how the policies, practices and narratives around plural policing reflect the influence of particular histories and geographies. The first three articles are focused primarily on the relationships which have emerged in the public sector through its own processes of pluralisation, in particular, through the introduction of policing auxiliaries or municipal policing in Scotland, England and The Netherlands. The fourth article considers both relationships and governance in pluralised policing in Paris, France. A detailed analysis of the governance of safety and security is taken up in the final two articles, examining the cases of Austria and Belgium. These articles clearly demonstrate that experiences of pluralised policing vary widely within Europe and call into question the assumed dominance of neo-liberal forces in this area
Exhaled Nitric Oxide is Not a Biomarker for Pulmonary Tuberculosis.
To reduce transmission of tuberculosis (TB) in resource-limited countries where TB remains a major cause of mortality, novel diagnostic tools are urgently needed. We evaluated the fractional concentration of exhaled nitric oxide (FeNO) as an easily measured, noninvasive potential biomarker for diagnosis and monitoring of treatment response in participants with pulmonary TB including multidrug resistant-TB in Lima, Peru. In a longitudinal study however, we found no differences in baseline median FeNO levels between 38 TB participants and 93 age-matched controls (13 parts per billion [ppb] [interquartile range (IQR) = 8-26] versus 15 ppb [IQR = 12-24]), and there was no change over 60 days of treatment (15 ppb [IQR = 10-19] at day 60). Taking this and previous evidence together, we conclude FeNO is not of value in either the diagnosis of pulmonary TB or as a marker of treatment response
