Video Activism and the Ambiguities of Counter-Surveillance

This paper examines the use of visual technologies by political activists in protest situations to monitor police conduct. Using interview data with Australian video activists, this paper seeks to understand the motivations, techniques and outcomes of video activism, and its relationship to counter-surveillance and police accountability. Our data also indicated that there have been significant transformations in the organization and deployment of counter-surveillance methods since 2000, when there were large-scale protests against the World Economic Forum meeting in Melbourne accompanied by a coordinated campaign that sought to document police misconduct. The paper identifies and examines two inter-related aspects of this: the act of filming and the process of dissemination of this footage. It is noted that technological changes over the last decade have led to a proliferation of visual recording technologies, particularly mobile phone cameras, which have stimulated a corresponding proliferation of images. Analogous innovations in internet communications have stimulated a coterminous proliferation of potential outlets for images Video footage provides activists with a valuable tool for safety and publicity. Nevertheless, we argue, video activism can have unintended consequences, including exposure to legal risks and the amplification of official surveillance. Activists are also often unable to control the political effects of their footage or the purposes to which it is used. We conclude by assessing the impact that transformations in both protest organization and media technologies might have for counter-surveillance techniques based on visual surveillance.

catena-poly[mercury(II)-di-mu-chloro-mu-pyridazine-kappa N-2 : N ']

The crystal structure of [HgCl2(Pyo)](n) (Pyo = pyridazine, C4H4N2) consists of chloride-bridged strands of octahedrally coordinated mercuric centers, connected by the two neighboring N atoms of pyridazine molecules. All atoms lie in special positions:Hg with site symmetry 2/m and the others on mirror planes.

catena-poly[mercury(II)-di-mu-bromo-mu-pyridazine-kappa N-2 : N ']

The crystal structure of [HgBr2(Pyo)](n) (Pyo = pyridazine, C4H4N2) consists of strands of octahedrally coordinated mercuric centers asymmetrically bridged by bromide and connected by the two neighboring N atoms of pyridazine molecules to complete the octahedral coordination of mercury. The Hg atoms lie on inversion centers.

Group 6 carbene complexes derived from lithiated azoles and the crystal structure of a molybdenum thiazolinylidene complex

Fischer-type (alkoxy)azolyl carbene complexes and Ofele-Lappert-type azolylinylidene complexes were synthesised by reaction of 1-phenylpyrazol-3 -yllithium, 4-methylthiazol-2-yllithium, benzothiazol-2-yllithium, 1-methylimidazol-2-yllithium with M(CO)(5)L (L = CO, THF or Cl-; M = Cr, Mo or W) and subsequent alkylation with CF3SO3CH3. The alkylation of Fischer-type carbene complexes containing an azolyl as the organic substituent proceeded via ring opening of tetrahydrofuran. When the alkylation is carried out in THF, the carbocation CH3O(CH2)(4)(+) acts as an electrophile. Protonation rather than alkylation of coordinated imidazolyl furnished cyclic imine complexes. Changing the donor atom of a coordinated thiazole from N to C by deprotonation and alkylation afforded a carbene complex. (C) 1999 Elsevier Science S.A. All rights reserved.

Autonomic management of multiple non-functional concerns in behavioural skeletons

We introduce and address the problem of concurrent autonomic management of different non-functional concerns in parallel applications build as a hierarchical composition of behavioural skeletons. We first define the problems arising when multiple concerns are dealt with by independent managers, then we propose a methodology supporting coordinated management, and finally we discuss how autonomic management of multiple concerns may be implemented in a typical use case. Being based on the behavioural skeleton concept proposed in the CoreGRID GCM, it is anticipated that the methodology will be readily integrated into the current reference implementation of GCM based on Java Pro Active and running on top of major grid middleware systems.

Investigation of the mechanism of repression of rRNA synthesis by an anticancer drug

Ribosome biogenesis is a fundamental cellular process which is tightly regulated in normal cells. A number of tumour suppressors and oncogenes could affect the production of ribosomes at different levels and an upregulation could lead to increased protein biosynthesis which is one of the characteristic features of all cancer cells. Ribosome biogenesis is a very complex process which requires coordinated transcription by all three nucleolar polymerases and the first event in this process is synthesis of ribosomal RNA (rRNA) by RNA Polymerase I (Pol I). Importantly, recent data has pictured rRNA transcription as a key regulator of whole ribosome biogenesis and therefore makes it a valid and very attractive target for anticancer therapy, as well as a perspective biomarker. However, at the moment there is only one known specific inhibitor of Pol I transcription (at stage one of clinical trials) and this makes it very difficult for the development of drugs which would target rRNA transcription and consequently ribosome biogenesis. We have recently discovered that antitumor alkaloid ellipticine (isolated in 1959 from the plant species Ochrosia) is a potent inhibitor of Pol I transcription (both in vitro and in vivo). Ellipticine and its derivatives are known as efficient topoisomerase II inhibitors and inhibitors of some kinases, however we have shown that these inhibitory activities and the ability of ellipticine to repress Pol I activity are unrelated. Moreover, our preliminary data suggests that ellipticine specifically targets Pol I transcription and it has no effect on transcription by Pol II and Pol III at the same time scale. The possible mechanisms of inhibition of Pol I transcription by ellipticines will be discussed.

qPCR utilization for the study of RNA Polymerase I transcription

Ribosome biogenesis is a fundamental cellular process tightly linked to cell growth and proliferation, which requires the coordinated transcription of all three nuclear polymerases. Synthesis of ribosomal RNA (rRNA) by RNA polymerase I (Pol I) has been suggested as a key regulator of ribosome biogenesis, and there is a strong link between transcription of ribosomal RNAs and cellular proliferation. This makes Pol I transcription a valid and attractive target for anticancer therapy. At the moment however there are only a small number of compounds that act as specific inhibitors of Pol I transcription and this makes it very difficult for the development of drugs which would target rRNA transcription and consequently ribosome biogenesis. Therefore, to aid in the development of new inhibitors of Pol I, high-throughput methods to monitor and detect changes in Pol I activity need to be developed. This current study aimed to address the question of whether or not quantitative PCR (qPCR) could be used to detect changes in rRNA production in cells under different conditions that repress Pol I activity i.e. serum starvation and drug treatment. Our results have shown that using primers and a hydrolysis probe designed for the 5’ETS region of the pre-rRNA molecule, rRNA levels in both treated and untreated cells could be determined by using qPCR.
Amplification resulted in formation of a single product and S1 nuclease protection assay confirmed the down-regulation of Pol I transcription. Following serum-starvation and drug treatment there was a dramatic reduction in the amount of 5’ETS transcript quantitated by both Sybr Green chemistry and the use of a fluorescently labelled hydrolysis probe. The optimization of the qPCR strategy will be discussed.

Research agendas for the sustainable management of tropical peatland in Malaysia

There is a need for coordinated research for the sustainable management of tropical peatland. Malaysia has 6% of global tropical peat by area and peatlands there are subject to land use change at an unprecedented rate. This paper describes a stakeholder engagement exercise that identified 95 priority research questions for peatland in Malaysia, organized into nine themes. Analysis revealed the need for fundamental scientific research, with strong representation across the themes of environmental change, ecosystem services, and conversion, disturbance and degradation. Considerable uncertainty remains about Malaysia's baseline conditions for peatland, including questions over total remaining area of peatland, water table depths, soil characteristics, hydrological function, biogeochemical processes and ecology. More applied and multidisciplinary studies involving researchers from the social sciences are required. The future sustainability of Malaysian peatland relies on coordinating research agendas via a ‘knowledge hub’ of researchers, strengthening the role of peatlands in land-use planning and development processes, stricter policy enforcement, and bridging the divide between national and provincial governance. Integration of the economic value of peatlands into existing planning regimes is also a stakeholder priority. Finally, current research needs to be better communicated for the benefit of the research community, for improved societal understanding and to inform policy processes.

Bis(1,4,7-trithiacyclononane-S,S ',S '')nickel(II) dibromide tetrahydrate

The Ni-II centre in the cation of the title compound, [Ni(C6H12S3)(2)]Br-2. 4H(2)O, occupies a crystallographic inversion centre and is octahedrally coordinated by six S-donors from two [9]aneS(3) ligands. Ni-S distances range from 2.3749 (16) to 2.4077 (15) Angstrom and S-Ni-S angles where both thia donors belong to the same ligand lie in a narrow range between 88.09 (5) and 88.67 (6)degrees. The water molecules participate in extensive hydrogen bonding with each other and with the Br- anions to form double chains with eight- and 12-membered hydrogen-bonded rings running along the crystallographic a direction.

Family Focused Practice in Mental Health Care: An Integrative Review

While mental health services are increasingly encouraged to engage in family-focused practice, it is a nebulous and poorly understood term. The aim of this paper was to examine and synthesize evidence on the concept and scope of family-focused practice in adult and child and youth mental health care settings. An integrative literature review method was used. Medline, Embase, CINAHL, PsycInfo and Proquest electronic databases were systematically searched forabstracts published in English between 1994-2014. Data were extracted and constant comparative analysis conducted with 40 included articles. Family-focused practice was conceptualised variously depending on who was included in the „family‟, whether the focus was family of origin or family of procreation, and the context of practice. As a finding of the review, six core and inter-related family-focused practices were identified: family care planning andgoal-setting; liaison between families and services; instrumental, emotional and social support; assessment; psychoeducation; and a coordinated system of care between families and services. While family is a troubled concept, „family‟ as defined by its members forms a basis for practice that is oriented to providing a „whole of family‟ approach to care. In order to strengthen familymembers‟ wellbeing and improve their individual and collective outcomes, key principles and practices of family-focused practice are recommended for clinicians and policy makers across mental health settings.

Burden of fungal disease in Ireland

Our objective was to estimate the burden of fungal disease on the island of Ireland, as part of a coordinated project estimating the global burden. Published epidemiology data describing fungal infection in Ireland were identified. Population and underlying disease data were collected for 2010 and a structured set of assumptions were applied to estimate burden of fungal disease based on immunosuppression, chronic disease, and other demographic information indicating predisposition to fungal infection. From Ireland’s population of 6.4 million, we estimate 117 000 patients develop significant fungal disease each year. By far the most common fungal disease is recurrent Candida vaginitis, with an estimated 95 000 episodes annually (3000 per 100 000 women). Other fungal diseases which may be less well recognized are severe asthma with fungal sensitization and allergic bronchopulmonary aspergillosis, with estimated episodes per year of 11 700 and 9000, respectively (182 and 140 per 100 000 population, respectively). The model also estimates 450 episodes of invasive aspergillosis, 200 of chronic pulmonary aspergillosis, 600 of oesophageal candidiasis and 450 of candidaemia per year (7, 3, 9 and 6 episodes per 100 000 population, respectively). This is, we believe, the first attempt to estimate the burden of fungal disease in our population and provides a basis for estimating its impact on human health and resource use.

Origin of extraordinarily high catalytic activity of Co3O4 and its morphological chemistry for CO oxidation at low temperature

Understanding and then designing efficient catalysts for CO oxidation at low temperature is one of the hottest topics in heterogeneous catalysis. Among the existing catalysts. Co3O4 is one of the most interesting systems: Morphology-controlled Co3O4 exhibits exceedingly high activity. In this study, by virtue of extensive density functional theory (OFT) calculations, the favored reaction mechanism in the system is identified. Through careful analyses on the energetics of elementary reactions on Co3O4(1 1 0)-A, Co3O4(1 1 0)-B, Co3O4(1 1 1) and Co3O4(1 0 0), which are the commonly exposed surfaces of Co3O4, we find the following regarding the relation between the activity and structure: (i) Co3+ is the active site rather than Co2+: and (ii) the three-coordinated surface oxygen bonded with three Co3+ may be slightly more reactive than the other two kinds of lattice oxygen, that is, the two-coordinated 0 bonded with one Co2+ and one Co3+ and the three-coordinated 0 bonded with one Co2+ and two Co3+. Following the results from Co3O4, we also extend the investigation to MnO2(1 1 0), Fe3O4(1 1 0), CuO(1 1 0) and CuO(1 1 1), which are the common metal oxide surfaces, aiming to understand the oxides in general. Three properties, such as the CO adsorption strength, the barrier of CO reacting with lattice 0 and the redox capacity, are identified to be the determining factors that can significantly affect the activity of oxides. Among these oxides, Co3O4 is found to be the most active one, stratifying all the three requirements. A new scheme to decompose barriers is introduced to understand the activity difference between lattice O-3c and O-2c on (1 1 0)-B surface. By utilizing the scheme, we demonstrate that the origin of activity variance lies in the geometric structures. (C) 2012 Elsevier Inc. All rights reserved.

BUCKLED LAYER STRUCTURE FOR ATOMIC ADSORPTION ON W(100) - THE (ROOT-2X-ROOT-2)R45-DEGREES NITROGEN STRUCTURE FROM ATLEED

Adsorption of 0.5 monolayer of N adatoms on W{100} results in a sharp (root 2 X root 2)R45 degrees LEED pattern. The only previous quantitative LEED study of this system gave a simple overlayer model with a Pendry R-factor of 0.55. An exhaustive search has been made of possible structures, including a novel vacancy reconstruction, displacive reconstructions and underlayer adsorption. From this work a new overlayer structure is derived with an R(p) value of 0.22, displaying a considerable buckling of 0.27 +/- 0.05 Angstrom within the second W layer and consequently involving large changes in the interlayer spacings of the surface. The N adatom is pseudo-five-fold coordinated to the W surface, bonding to a second-layer W atom with a nearest-neighbour bond length of 2.13 Angstrom and with the four next-nearest-neighbour W atoms in the surface plane at 2.27 Angstrom. The structure does not resolve the work function anomaly observed on this surface.

Combining and integrating life /social sciences and citizen trainers in Nurse Education - a N. Ireland initiative

Before commencement of the academic year 2012/2013 the social sciences, public health and the biomedical sciences were taught to separate modules. This reinforced the idea off separate disciplines certainly for some of the younger students and a failure to appreciate the interconnectedness (whole person) perspective on health; separately modules taught and assessed in separate silos. There was limited understanding by the lecturers of the other areas that they were not teaching to -reflecting perhaps a dis-coordinated approach to health sciences (Mason and Whitehead 2003). As a result of significant discussion and interdisciplinary negotiation the life, social sciences public health/ health education were drawn together in the one module for the academic year 2012/13. The module provides the undergraduate students with an introduction to an understanding of Life Sciences, psychology, sociology and public health and their contribution within the context of nursing and midwifery. Each week’s teaching seeks to reflect against the other module delivered in first year - addressing clinical skills. The teaching is developing innovative e-learning approaches, including the use of a virtual community. The intention is to provide the student with a more integrated understanding and teaching to the individual’s health and to health within a social context (Lin 2001; Iles- Shih 2011). The focus is on health promotion rather than disease management. The module runs in three phases across the student’s first-year and teachers to the field of adult mental health, learning disability, children’s nursing and the midwifery students -progressively building on the student’s clinical experience. The predominant focus of the module remains on health and reflecting aspects of life and social life within N. Ireland. One of the particular areas of interest and an area of particular sensitivity is engaging the students to the context of the Northern Ireland civil unrest (the Troubles); this involves a co-educational initiative with service users, only previously attempted with social work students (Duffy 2012). The service users are represented by WAVE an organisation offering care and support to bereaved, traumatised or injured as a result of the violent civil conflict `the Troubles’. The `Troubles’ had ranged over an extended period and apart from the more evident and visual impact of death and injury, the community is marked by a disproportionate level of civil unrest, the extremes of bereavement, imprisonment, displacement antisocial behaviour and family dysfunction (Coulter et al. 2012). As co-educators with the School of Nursing and Midwifery, WAVE deliver a core lecture (augmented by online material), then followed by tutorials. The tutorials are substantially led by those who had been involved with and experienced loss and trauma as a result of the conflict (Health Service users) as `citizen trainers’ and provide an opportunity for them to share their experience and their recollection of personal interaction with nursing and midwifery students; in improving their understanding of the impact of `The Troubles’ on patients and clients affected by the events (Coulter et al. 2012) and to help better provide a quality of care cognisant of the particular needs of those affected by `the Troubles’ in N.Ireland. This approach is relatively unique to nursing in N. Ireland in that it involves many of those directly involved with and injured by the `Troubles’ as `citizen trainers’ and clearly reflects the School’s policy of progressively engaging with users and carers of nursing and midwifery services as co-educators to students (Repper & Breeze 2006). Only now could perhaps such a sensitive level of training to student nurses and midwives be delivered across communities with potential educative lessons for other communities experiencing significant civil unrest and sectarian conflict.

PET/CT imaging for target volume delineation in curative intent radiotherapy of non-small cell lung cancer: IAEA consensus report 2014

This document describes best practice and evidence based recommendations for the use of FDG-PET/CT for the purposes of radiotherapy target volume delineation (TVD) for curative intent treatment of non-small cell lung cancer (NSCLC). These recommendations have been written by an expert advisory group, convened by the International Atomic Energy Agency (IAEA) to facilitate a Coordinated Research Project (CRP) aiming to improve the applications of PET based radiation treatment planning (RTP) in low and middle income countries. These guidelines can be applied in routine clinical practice of radiotherapy TVD, for NSCLC patients treated with concurrent chemoradiation or radiotherapy alone, where FDG is used, and where a calibrated PET camera system equipped for RTP patient positioning is available. Recommendations are provided for PET and CT image visualization and interpretation, and for tumor delineation using planning CT with and without breathing motion compensation.
