Understanding the role of performance targets in transport policy

The measurement of performance in the public sector has become increasingly important in recent years and it is now commonplace for transport organisations, and local and national governments, to publish performance goals for service supply and quality. Such commitments, when time referenced, are known as targets. This paper explain how changes in management style, consumer rights legislation, contractual obligations and other factors have combined to make management-by targets increasingly common in the public sector. The advantages and disadvantages of management-by-targets are illustrated through discussion of the processes and experience of setting transport targets in UK national transport policy. We conclude that while some of the targets have had a significant impact on policy makers, managers and their agents, the effects have not always been as intended

Are the police embracing evidence-informed practice? A view from England and Wales

The What Works Centre for Crime Reduction (WWCCR) in the UK’s College of Policing has a key role in promoting the use of research in policing. Since 2014, the WWCCR has aimed to review - and make accessible - research to better inform and target crime reduction and to build police capacity to identify, evaluate and apply research evidence to practice. This comes amidst significant changes to entry requirements for policing in the UK as part of efforts to further professionalise the service and prepare for future challenges in policing. We report findings from in-depth interviews with senior police officers from forces across England and Wales, conducted as part of a three-year evaluation of the WWCCR. These interviews explored the traction of ‘evidence-based practice’ among senior officers and showed shifts over time in their accounts of the value placed on research and how it is promoted and used within their force. Additionally, an online survey across policing ranks, conducted in 2016, found differences by seniority in perceptions about the relevance of research for policing, and the level of organisational support for it. Findings are used to consider the status of research evidence in policing and its development within a policing profession

Omacetaxine may have a role in chronic myeloid leukaemia eradication through downregulation of Mcl-1 and induction of apoptosis in stem/progenitor cells

Chronic myeloid leukaemia (CML) is maintained by a rare population of tyrosine kinase inhibitor (TKI)-insensitive malignant stem cells. Our long-term aim is to find a BcrAbl-independent drug that can be combined with a TKI to improve overall disease response in chronic-phase CML. Omacetaxine mepesuccinate, a first in class cetaxine, has been evaluated by clinical trials in TKI-insensitive/resistant CML. Omacetaxine inhibits synthesis of anti-apoptotic proteins of the Bcl-2 family, including (myeloid cell leukaemia) Mcl-1, leading to cell death. Omacetaxine effectively induced apoptosis in primary CML stem cells (CD34<sup>+</sup>38<sup>lo</sup>) by downregulation of Mcl-1 protein. In contrast to our previous findings with TKIs, omacetaxine did not accumulate undivided cells <i>in vitro</i>. Furthermore, the functionality of surviving stem cells following omacetaxine exposure was significantly reduced in a dose-dependant manner, as determined by colony forming cell and the more stringent long-term culture initiating cell colony assays. This stem cell-directed activity was not limited to CML stem cells as both normal and non-CML CD34<sup>+</sup> cells were sensitive to inhibition. Thus, although omacetaxine is not leukaemia stem cell specific, its ability to induce apoptosis of leukaemic stem cells distinguishes it from TKIs and creates the potential for a curative strategy for persistent disease

Skills for sustainable development: transforming vocational education and training beyond 2015

There have been recent calls to transform VET and to transform development. This double call leads us to ask: how can skills development best support development that is sustainable for individuals, communities and the planet, whilst promoting social justice and poverty reduction? In considering this question we critique the idea of green skills for the green economy as being inadequate for achieving a transformed and transformative VET that shifts the target from economic growth to the well-being of individuals, and that enables vocational education to play a role in challenging and transforming society and work. Rather, we argue that we must see human development and sustainable development as inseparable, and plan and evaluate VET for its contribution to these. Such an approach must be grounded in a view of work, and hence skills for work, that is decent, life-enhancing, solidaristic, environmentally-sensitive and intergenerationally-aware. It must confront the reality that much current VET is complicit in preparing people for work that lacks some or all of these characteristics. It must be concerned with poverty, inequality and injustice and contribute to their eradication. It must be supportive of individuals’ agency, whilst also reflecting a careful reading of the structures that too often constrain them. In doing all this it must minimise the costs and risks of any transformation for the poor and seek to lock them into better individual and collective lives, not out of them. Finally, it must transform skills, work and the world in ways that are truly sustainable of the people of today but also those who are to inhabit the earth tomorrow

Removal of babies at birth and the moral distress of midwives

Background Midwives and nurses appear vulnerable to moral distress when caring for women whose babies are removed at birth. They may experience professional dissatisfaction and their relationships with women, families and colleagues may be compromised. The impact of moral distress may manifest as anger, guilt, frustration, anxiety and a desire to give up their profession. While there has been much attention exploring the concept of moral distress in midwifery, this is the first study to explore its association in this context. Aim This article explores midwives’ experiences of moral distress when providing care to women whose babies were removed at birth and gives valuable insight into an issue nurses and midwives encounter in their profession. Methods Four mothers and eight midwives took part in this research. Narrative inquiry incorporating photo-elicitation techniques was used to generate data; mothers were interviewed face to face and midwives through focus groups. The images and audio data were collected, transcribed and analysed for emerging themes. For the purpose of this article, only the midwives’ stories are reported. This research received a favourable ethical opinion from the University of Surrey Ethics committee. Ethical considerations This study received a favourable ethical approval from a higher education institutes ethics committee. Results Midwives who care for women whose babies are removed at birth report it as one of the most distressing areas of contemporary clinical practice. Furthermore, they report feelings of guilt, helplessness and betrayal of the midwife–mother relationship. Many of the midwives in this study state that these experiences stay with them for a long time, far more than more joyful aspects of their role. Conclusion Midwives experience moral distress. Support systems, education and training must be available to them if we are to reduce the long-term impact upon them, alleviate their distress and prevent them from leaving the profession. </jats:sec

Eliciting a predatory response in the eastern corn snake (Pantherophis guttatus) using live and inanimate sensory stimuli: implications for managing invasive populations

North America's Eastern corn snake (Pantherophis guttatus) has been introduced to several islands throughout the Caribbean and Australasia where it poses a significant threat to native wildlife. Invasive snake control programs often involve trapping with live bait, a practice that, as well as being costly and labour intensive, raises welfare and ethical concerns. This study assessed corn snake response to live and inanimate sensory stimuli in an attempt to inform possible future trapping of the species and the development of alternative trap lures. We exposed nine individuals to sensory cues in the form of odour, visual, vibration and combined stimuli and measured the response (rate of tongue-flick [RTF]). RTF was significantly higher in odour and combined cues treatments, and there was no significant difference in RTF between live and inanimate cues during odour treatments. Our findings suggest chemical cues are of primary importance in initiating predation and that an inanimate odour stimulus, absent of simultaneous visual and vibratory cues, is a potential low-cost alternative trap lure for the control of invasive corn snake populations

Evolutionary Toggling of Vpx/Vpr Specificity Results in Divergent Recognition of the Restriction Factor SAMHD1

SAMHD1 is a host restriction factor that blocks the ability of lentiviruses such as HIV-1 to undergo reverse transcription in myeloid cells and resting T-cells. This restriction is alleviated by expression of the lentiviral accessory proteins Vpx and Vpr (Vpx/Vpr), which target SAMHD1 for proteasome-mediated degradation. However, the precise determinants within SAMHD1 for recognition by Vpx/Vpr remain unclear. Here we show that evolution of Vpx/Vpr in primate lentiviruses has caused the interface between SAMHD1 and Vpx/Vpr to alter during primate lentiviral evolution. Using multiple HIV-2 and SIV Vpx proteins, we show that Vpx from the HIV-2 and SIVmac lineage, but not Vpx from the SIVmnd2 and SIVrcm lineage, require the C-terminus of SAMHD1 for interaction, ubiquitylation, and degradation. On the other hand, the N-terminus of SAMHD1 governs interactions with Vpx from SIVmnd2 and SIVrcm, but has little effect on Vpx from HIV-2 and SIVmac. Furthermore, we show here that this difference in SAMHD1 recognition is evolutionarily dynamic, with the importance of the N- and C-terminus for interaction of SAMHD1 with Vpx and Vpr toggling during lentiviral evolution. We present a model to explain how the head-to-tail conformation of SAMHD1 proteins favors toggling of the interaction sites by Vpx/Vpr during this virus-host arms race. Such drastic functional divergence within a lentiviral protein highlights a novel plasticity in the evolutionary dynamics of viral antagonists for restriction factors during lentiviral adaptation to its hosts. © 2013 Fregoso et al

Proximity to Sports Facilities and Sports Participation for Adolescents in Germany

Objectives - To assess the relationship between proximity to specific sports facilities and participation in the corresponding sports activities for adolescents in Germany. Methods - A sample of 1,768 adolescents aged 11–17 years old and living in 161 German communities was examined. Distances to the nearest sports facilities were calculated as an indicator of proximity to sports facilities using Geographic Information Systems (GIS). Participation in specific leisure-time sports activities in sports clubs was assessed using a self-report questionnaire and individual-level socio-demographic variables were derived from a parent questionnaire. Community-level socio-demographics as covariates were selected from the INKAR database, in particular from indicators and maps on land development. Logistic regression analyses were conducted to examine associations between proximity to the nearest sports facilities and participation in the corresponding sports activities. Results - The logisitic regression analyses showed that girls residing longer distances from the nearest gym were less likely to engage in indoor sports activities; a significant interaction between distances to gyms and level of urbanization was identified. Decomposition of the interaction term showed that for adolescent girls living in rural areas participation in indoor sports activities was positively associated with gym proximity. Proximity to tennis courts and indoor pools was not associated with participation in tennis or water sports, respectively. Conclusions - Improved proximity to gyms is likely to be more important for female adolescents living in rural areas

A hysteretic multiscale formulation for nonlinear dynamic analysis of composite materials

This article has been made available through the Brunel Open Access Publishing Fund.A new multiscale finite element formulation is presented for nonlinear dynamic analysis of heterogeneous structures. The proposed multiscale approach utilizes the hysteretic finite element method to model the microstructure. Using the proposed computational scheme, the micro-basis functions, that are used to map the microdisplacement components to the coarse mesh, are only evaluated once and remain constant throughout the analysis procedure. This is accomplished by treating inelasticity at the micro-elemental level through properly defined hysteretic evolution equations. Two types of imposed boundary conditions are considered for the derivation of the multiscale basis functions, namely the linear and periodic boundary conditions. The validity of the proposed formulation as well as its computational efficiency are verified through illustrative numerical experiments
