Grassroots mobilisations against waste disposal sites in Greece

The government of Greece has gained notoriety for its failure to implement EU environmental directives in general, and is criticised specifically for its lack of an effective plan for the safe disposal of waste. Local mobilisations against a series of planned 'Sanitary Waste Disposal Sites' (HETAs) in three municipalities of Attica are examined. Should such protests be classified as NIMBY (not in my backyard)? Or do they present broader claims of justice and equity? Qualitative analysis of the protesters' on-line campaign material reveals that while these mobilisations do demonstrate some NIMBY characteristics, such campaigns should rather be perceived as ad hoc mobilisations reflective of tensions of late modernity. The public's mistrust of science and concerns about democratic deficit and accountability, as well as different perceptions of risk, are prominent.

Dispersion interactions in room-temperature ionic liquids: Results from a non-empirical density functional

The role of dispersion or van de Waals (VDW) interactions in imidazolium-based room-temperature ionic liquids is studied within the framework of density functional theory, using a recently developed non-empirical functional [M. Dion, H. Rydberg, E. Schroder, D. C. Langreth, and B. I. Lundqvist, Phys. Rev. Lett. 92, 246401 (2004)], as efficiently implemented in the SIESTA code [G. Roman-Perez and J. M. Soler, Phys. Rev. Lett. 103, 096102 (2009)]. We present results for the equilibrium structure and lattice parameters of several crystalline phases, finding a general improvement with respect to both the local density (LDA) and the generalized gradient approximations (GGA). Similar to other systems characterized by VDW bonding, such as rare gas and benzene dimers as well as solid argon, equilibrium distances and volumes are consistently overestimated by approximate to 7%, compared to -11% within LDA and 11% within GGA. The intramolecular geometries are retained, while the intermolecular distances and orientations are significantly improved relative to LDA and GGA. The quality is superior to that achieved with tailor-made empirical VDW corrections ad hoc [M. G. Del Popolo, C. Pinilla, and P. Ballone, J. Chem. Phys. 126, 144705 (2007)]. We also analyse the performance of an optimized version of this non-empirical functional, where the screening properties of the exchange have been tuned to reproduce high-level quantum chemical calculations [J. Klimes, D. Bowler, and A. Michaelides, J. Phys.: Condens. Matter 22, 074203 (2010)]. The results for solids are even better with volumes and geometries reproduced within 2% of experimental data. We provide some insight into the issue of polymorphism of [bmim][Cl] crystals, and we present results for the geometry and energetics of [bmim][Tf] and [mmim][Cl] neutral and charged clusters, which validate the use of empirical force fields.

Evolutionary Requirements for Next-Generation Dataflow-Based FPGA System Design

The use of dataflow digital signal processing system modelling
and synthesis techniques has been a fruitful research theme for many years and has yielded many powerful rapid system synthesis and optimisation capabilities. However, recent years have seen the spectrum of languages and techniques splinter in an application specific manner, resulting in an ad-hoc design process which is increasingly dependent on the particular application under development. This poses a major problem for automated toolflows attempting to provide rapid system synthesis for a wide ranges of applications. By analysing a number of dataflow FPGA implementation case studies, this paper shows that despit ethis common traits may be found in current techniques, which fall largely into three classes. Further, it exposes limitations pertaining to their ability to adapt algorith models to implementations for different operating environments and target platforms.

Developing tomorrow's leaders-Evidence of global talent management in multinational enterprises

Organizations are becoming relentless in managing and developing their key talent. This is a view, however, largely based on anecdote rather than reliable empirical evidence. Utilizing data from 260 multinational enterprises (MNEs), this paper helps redress this deficit. Specifically, this paper explores the extent to which MNEs engage in global talent management (GTM) and deciphers some of the factors which may explain the use and non-use of GTM practices. In so doing, we find that although a significant number of MNEs have systems and mechanisms in place to strategically identify and develop their talent many more seemingly adopt an ad hoc or haphazard approach. For instance, less than half of all MNEs have both global succession planning and formal management development programs for their high-potentials. Consequently it seems that there is a considerable distance yet to be travelled to arrive at a universal appreciation of the need to strategically manage one's key employees. We find the size of the MNE has a significant effect on GTM system usage-larger MNEs are more likely to undertake GTM. Other significant, positive influences include whether products or services are standardized regionally or globally, and if the MNE has a global human resources policy formation body. Of considerable interest is the finding that MNEs operating in the low-tech/low-cost sectors are significantly more likely to have formal global systems to identify and develop high-potentials. © 2009 Elsevier Inc.

Invisible from View: Leaving and Aftercare Provision in the Republic Of Ireland

The adequacy of provisions for young people leaving care and in aftercare in the Republic of Ireland have been the subject of recent policy attention. A landmark report, the Ryan Report (2009), into historic abuse in state institutions recommended strengthening provisions in this area. However, the legislative basis for aftercare remains relatively weak and services for young people leaving care remain ad hoc and regionally variable. This article outlines the current context of leaving and aftercare provision in the Republic of Ireland and traces some of the recent policy debates and recommendations in this area. A genealogical analysis of leaving care and aftercare provision highlights that this issue has historically only emerged as a concern in the context in which young people leaving the care system are perceived as a ‘threat’ to social order. It is argued that the failure to adequately reform leaving and aftercare provision is reflective of wider social inequality and of a context in which young people in care are largely invisible from view.

Multidimensional poverty measurement in Europe:An application of the adjusted headcount approach

As awareness of the limitations of relying solely on income to measure poverty has become more widespread, attention has been increasingly focused on multi-dimensional approaches, to the point where the EU has adopted a multidimensional poverty and social exclusion target for 2020. The rationale advanced is that the computation of a multidimensional poverty index is an effective way of communicating in a political environment, and a necessary tool in order to monitor 27 different national situations. By contrast with the rather ad hoc way in which the EU 2020 poverty target has been framed and rationalised, the adjusted head count ratio applied here has a number of desirable axiomatic properties. It constitutes a significant improvement on union and intersection approaches and allows for the decomposition of multidimensional poverty in terms of dimensions of deprivation and socio-economic attributes. Since understanding poverty as multidimensional does not necessarily require constructing a multidimensional poverty index, on the basis of our analysis we provide a more general consideration of the value of developing a multidimensional index of poverty for the European Union.

A Vector Approach for the Analysis and Synthesis of Directional Modulation Transmitters

In order to formalize and extend on previous ad-hoc analysis and synthesis methods a theoretical treatment using vector representations of directional modulation (DM) systems is introduced and used to achieve DM transmitter characteristics. An orthogonal vector approach is proposed which allows the artificial orthogonal noise concept derived from information theory to be brought to bear on DM analysis and synthesis. The orthogonal vector method is validated and discussed via bit error rate (BER) simulations.

Dense Multiperson Tracking with Robust Hierarchical Linear Assignment

We introduce a novel dual-stage algorithm for online multi-target tracking in realistic conditions. In the first stage, the problem of data association between tracklets and detections, given partial occlusion, is addressed using a novel occlusion robust appearance similarity method. This is used to robustly link tracklets with detections without requiring explicit knowledge of the occluded regions. In the second stage, tracklets are linked using a novel method of constraining the linking process that removes the need for ad-hoc tracklet linking rules. In this method, links between tracklets are permitted based on their agreement with optical flow evidence. Tests of this new tracking system have been performed using several public datasets.

Realising Justice for victims before the International Criminal Court

The International Criminal Court (ICC) has been celebrated for its innovative victim provisions, which enable victims to participate in proceedings, avail of protection measures and assistance, and to claim reparations. The impetus for incorporating victim provisions within the ICC, came from victims’ dissatisfaction with the ad hoc tribunals in providing them with more meaningful and tangible justice.1 The International Criminal Tribunals for the former Yugoslavia and Rwanda (ICTY/R) only included victim protection measures, with no provisions for victims to participate in proceedings nor to claim reparations at them. Developments in domestic and international law, in particular human rights such as the 1985 UN Declaration on Justice for Victims and the UN Guidelines on Remedy and Reparations, and transitional justice mechanisms, such as truth commissions and reparations bodies, have helped to expand the notion of justice for international crimes to be more attuned to victims as key stakeholders in dealing with such crimes.

With the first convictions secured at the ICC and the victim participation and reparation regime taking form, it is worth evaluating the extent to which these innovative provisions have translated into justice for victims. The first part of this paper outlines what justice for victims of international crimes entails, drawing from victimology and human rights. The second section surveys the extent to which the ICC has incorporated justice for victims, in procedural and substantive terms, before concluding in looking beyond the Court to how state parties can complement the ICC in achieving justice for victims. This paper argues that while much progress has been made to institutionalise justice for victims within the Court, there is much more progress needed to evolve and develop justice for victims within the ICC to avoid dissatisfaction of past tribunals.

A necessarily complex model to explain the biogeography of the amphibians and reptiles of Madagascar

Pattern and process are inextricably linked in biogeographic analyses, though we can observe pattern, we must infer process. Inferences of process are often based on ad hoc comparisons using a single spatial predictor. Here, we present an alternative approach that uses mixed-spatial models to measure the predictive potential of combinations of hypotheses. Biodiversity patterns are estimated from 8,362 occurrence records from 745 species of Malagasy amphibians and reptiles. By incorporating 18 spatially explicit predictions of 12 major biogeographic hypotheses, we show that mixed models greatly improve our ability to explain the observed biodiversity patterns. We conclude that patterns are influenced by a combination of diversification processes rather than by a single predominant mechanism. A ‘one-size-fits-all’ model does not exist. By developing a novel method for examining and synthesizing spatial parameters such as species richness, endemism and community similarity, we demonstrate the potential of these analyses for understanding the diversification history of Madagascar’s biota.

Positioning Clinical Nurse Specialists and Nurse Practitioners as Change Champions to Implement a Pain Protocol in Long-Term Care

Pain management for older adults in long-term care (LTC) has been recognized as a problem internationally. The purpose of this study was to explore the role of a clinical nurse specialist (CNS) and nurse practitioner (NP) as change champions during the implementation of an evidence-based pain protocol in LTC. In this exploratory, multiple-case design study, we collected data from two LTC homes in Ontario, Canada. Three data sources were used: participant observation of an NP and a CNS for 18 hours each over a 3-week period; CNS and NP diaries recording strategies, barriers, and facilitators to the implementation process; and interviews with members of the interdisciplinary team to explore perceptions about the NP and CNS role in implementing the pain protocol. Data were analyzed using thematic content analysis. The NP and CNS used a variety of effective strategies to promote pain management changes in practice including educational outreach with team members, reminders to nursing staff to highlight the pain protocol and educate about practice changes, chart audits and feedback to the nursing staff, interdisciplinary working group meetings, ad hoc meetings with nursing staff, and resident assessment using advanced skills. The CNS and NP are ideal champions to implement pain management protocols and likely other quality improvement initiatives.

Restorative Justice and Sex Offending

This essay examines the origins and uses of restorative justice with sexual offending and the contemporary challenges and controversies surrounding this. It charts the range of ad hoc initiatives which have sought to apply a restorative form of intervention with violent or sexual offending from first time and ‘acquaintance’ rape as well as young sexual abusers to high risk sexual offenders in the form of circles of support and accountability. Such schemes are often presented as a counter to the failings of retributive forms of justice and are premised on Braithwaite’s (1989) notion of ‘reintegrative shaming’ that seek to reintegrate offenders into the community. Critics of restorative justice traditionally put forward a number of core objectives when restorative justice is applied to serious forms of offending such as sexual offending. The essay also sets out and seeks to counter these principal challenges and how they may be overcome. For the most part, however, restorative justice has failed to reach its potential as a fully fledged sentencing rationale in being applied as a mainstream response to a wide range of offending including that at the higher end of the spectrum. The essay also seeks to examine barriers to restorative justice within contemporary penal policy and to highlight some of the most controversial applications of the restorative paradigm including those related to clergy sexual abuse. It concludes by offering some thoughts on the future of restorative justice as a mainstream responses to serious forms of offending.

(Re) making trajectories: Eviction, control and power

The City of Cairo's experienced a major shift in its urban planning attitude and practice since the mid 1970s which mostly validated elements of economic planning while neutralizing its social aspects. This ad hoc approach escalated conflict in planning politics over the control of space between tiers of the planning institution and the locals leading to rigorous planning actions among major stakeholders such as eviction and control of spaces. The article examines how institutional claims over space reassembled alternative definitions of quality of life in one of Cairo's oldest quarters, and how ambitious planning schemes were mostly driven by entrepreneurial rather than societal. Based on first-hand interviews and visuals, the article aims to reveal the local's struggle to survive such interventions with attention to their daily negotiations in place.

An official American thoracic society research statement: Comparative effectiveness research in pulmonary, critical care, and sleep medicine

Background: Comparative effectiveness research (CER) is intended to inform decision making in clinical practice, and is central to patientcentered outcomes research (PCOR). Purpose: To summarize key aspects of CER definitions and provide examples highlighting the complementary nature of efficacy and CER studies in pulmonary, critical care, and sleep medicine. Methods: An ad hoc working group of the American Thoracic Society with experience in clinical trials, health services research, quality improvement, and behavioral sciences in pulmonary, critical care, and sleepmedicinewas convened. The group used an iterative consensus process, including a reviewbyAmerican Thoracic Society committees and assemblies. Results: The traditional efficacy paradigm relies on clinical trials with high internal validity to evaluate interventions in narrowly defined populations and in research settings. Efficacy studies address the question, "Can it work in optimal conditions?" The CER paradigm employs a wide range of study designs to understand the effects of interventions in clinical settings. CER studies address the question, "Does it work in practice?" The results of efficacy and CER studies may or may not agree. CER incorporates many attributes of outcomes research and health services research, while placing greater emphasis on meeting the expressed needs of nonresearcher stakeholders (e.g., patients, clinicians, and others). Conclusions: CER complements traditional efficacy research by placing greater emphasis on the effects of interventions in practice, and developing evidence to address the needs of the many stakeholders involved in health care decisions. Stakeholder engagement is an important component of CER. Copyright © 2013 by the American Thoracic Society.

Properties of extragalactic dust inferred from linear polarimetry of Type Ia Supernovae

Aims
The aim of this paper is twofold: 1) to investigate the properties of extragalactic dust and compare them to what is seen in the Galaxy; 2) to address in an independent way the problem of the anomalous extinction curves reported for reddened Type Ia Supernovae (SN) in connection to the environments in which they explode. 

Methods
The properties of the dust are derived from the wavelength dependence of the continuum polarization observed in four reddened Type Ia SN: 1986G, 2006X, 2008fp, and 2014J. The method is based on the observed fact that Type Ia SN have a negligible intrinsic continuum polarization. This and their large luminosity makes them ideal tools to probe the dust properties in extragalactic environments.

Results
All four objects are characterized by exceptionally low total-to-selective absorption ratios (R<inf>V</inf>) and display an anomalous interstellar polarization law, characterized by very blue polarization peaks. In all cases the polarization position angle is well aligned with the local spiral structure. While SN 1986G is compatible with the most extreme cases of interstellar polarization known in the Galaxy, SN 2006X, 2008fp, and 2014J show unprecedented behaviours. The observed deviations do not appear to be connected to selection effects related to the relatively large amounts of reddening characterizing the objects in the sample.

Conclusions
The dust responsible for the polarization of these four SN is most likely of interstellar nature. The polarization properties can be interpreted in terms of a significantly enhanced abundance of small grains. The anomalous behaviour is apparently associated with the properties of the galactic environment in which the SN explode, rather than with the progenitor system from which they originate. For the extreme case of SN 2014J, we cannot exclude the contribution of light scattered by local material; however, the observed polarization properties require an ad hoc geometrical dust distribution.
