Secondary instability and tertiary states in rotating plane Couette flow
Authors: Daly C. A. , Schneider Tobias M. , Schlatter Philipp , Peake N. 
Published: November 2014

AbstractRecent experimental studies have shown rich transition behaviour in rotating plane Couette flow (RPCF). In this paper we study the transition in supercritical RPCF theoretically by determination of equilibrium and periodic orbit tertiary states via Floquet analysis on secondary Taylor vortex solutions. Two new tertiary states are discovered which we name oscillatory wavy vortex flow (oWVF) and skewed vortex flow (SVF). We present the bifurcation routes and stability properties of these new tertiary states and, in addition, we describe a bifurcation procedure whereby a set of defected wavy twist vortices is approached. Further to this, transition scenarios at flow parameters relevant to experimental works are investigated by computation of the set of stable attractors which exist on a large domain. The physically observed flow states are shown to share features with states in our set of attractors.
High stability, single frequency, 300 mJ, 130 ps laser pulse generation based on stimulated Brillouin scattering pulse compression
Authors: Zhu Xuehua , Lu Zhiwei , Wang Yulei 
Published: November 2014

AbstractWe obtained the output of single frequency laser pulses with an average pulse-width of 136 ps and the minimum of 123 ps based on stimulated Brillouin scattering pulse compression pumped by an 8 ns-pulse-width, 1064 nm-wavelength Q-switched Nd:YAG laser. The pulse-width stability of the output is about 4.1% while that of the pump pulses is about 1.1%, the highest energy conversion efficiency is about 85%, and the single pulse energy is above 300 mJ.
WHAT’S IN A NAME? DEVELOPING DEFINITIONS FOR COMMON HEALTH TECHNOLOGY ASSESSMENT PRODUCT TYPES OF THE INTERNATIONAL NETWORK OF AGENCIES FOR HEALTH TECHNOLOGY ASSESSMENT (INAHTA)

Published: November 2014

Objectives: A mapping exercise was undertaken to determine how HTA is being described and conducted across the International Network of Agencies for Health Technology Assessment (INAHTA), with the aim of harmonizing terminologies and approaches.Methods: Three progressive surveys were undertaken. In 2010, INAHTA agencies were asked to provide details on all of their HTA products. In 2013, additional information was sought on key methodological characteristics of five of the most common HTA product types. Subsequently, final agreement was sought on three proposed product types.Results: Forty-five HTA agencies responded to at least one of the surveys. In 2010, twenty-one agencies reported publishing over seventy named HTA products. Core domains associated with full HTA reports were reported by a third of agencies but were labeled differently, so products were classified according to product type (n = 17). Agencies producing short, tailored products increased between 2010 and 2013, with the publication of rapid reviews doubling from 33 percent to 66 percent. In 2013, half of the agencies adapted their common HTA products from documents produced by other agencies. A consensus (>70 percent) was achieved on definitions for HTA reports, mini-HTAs, and rapid reviews.Conclusions: The product label for an HTA is not always indicative of its content. Terminology has, therefore, been agreed to make explicit the trade-off between rigor and timeliness in three common HTA product types. An INAHTA Product Type (IPT) Mark has been created to identify each of these. It is hoped this will further facilitate HTA adaptation between agencies and reduce duplication of effort.
Rapid Measurement of Molecular Transport and Interaction inside Living Cells Using Single Plane Illumination
Authors: Hedde Per Niklas , Stakic Milka , Gratton Enrico 
Published: November 2014

AbstractThe ability to measure biomolecular dynamics within cells and tissues is very important to understand fundamental physiological processes including cell adhesion, signalling, movement, division or metabolism. Usually, such information is obtained using particle tracking methods or single point fluctuation spectroscopy. We show that image mean square displacement analysis, applied to single plane illumination microscopy data, is a faster and more efficient way of unravelling rapid, three-dimensional molecular transport and interaction within living cells. From a stack of camera images recorded in seconds, the type of dynamics such as free diffusion, flow or binding can be identified and quantified without being limited by current camera frame rates. Also, light exposure levels are very low and the image mean square displacement method does not require calibration of the microscope point spread function. To demonstrate the advantages of our approach, we quantified the dynamics of several different proteins in the cyto- and nucleoplasm of living cells. For example, from a single measurement, we were able to determine the diffusion coefficient of free clathrin molecules as well as the transport velocity of clathrin-coated vesicles involved in endocytosis. Used in conjunction with dual view detection, we further show how protein-protein interactions can be quantified.

Abstract

Background
Nearly all patients with malignant glioma will have disease recurrence. Our purpose was to define the treatment toxicity and efficacy of concurrent bevazicumab (BVZ) with hypofractionated stereotactic radiosurgery (SRS) of relatively larger targets for patients with recurrent MG.

Methods
A retrospective review of 21 patients with recurrent malignant glioma (18 glioblastoma, 3 WHO grade III glioma), treated at initial diagnosis with surgery and standard chemoradiation, was performed. All patients had concurrent BVZ with hypofractionatedSRS, 30 Gy in 5 fractions, with or without concurrent chemotherapy (temozolomide or CCNU).

Results
Median patient age was 54 years, median Karnofsky Performance Status was 80, and median target size was 4.3 cm (range, 3.4–7.5 cm). Eleven patients (52%) had previously failed BVZ. One patient had grade 3 toxicities (seizures, dysphasia), which resolved with inpatient admission and intravenous steroids/antiepileptics. Treatment-related toxicities were grade 3 (n = 1), grade 2 (n = 9), and grade 0–1 (n = 11). Kaplan-Meier median progression-free survival and overall survival estimates (calculated from start of SRS) for GBM patients (n = 18) were 11.0 and 12.5 months, respectively. Concurrent chemotherapy did not appear to show any statistically significant efficacy benefit or have any propensity for toxicity.

Conclusion
BVZ concurrent with hypofractionated SRS was well tolerated by this cohort of patients with relatively larger targets. Ongoing randomized trials with more moderate radiotherapy dosing may help establish the efficacy of this regimen, though intricacies of this approach, including patient selection, radiation target volume delineation/size, and optimal radiation dose, will need further evaluation.

Published: November 2014

PurposeThe purpose of this paper is to develop innovative geometry for gears aiming low power loss and easy manufacturing.Design/methodology/approachNew gear profiles were developed and studied, and gears were built accordingly and then tested using an FZG machine.FindingsResults from the experimental tests revealed the influence of the profile modifications on the operating temperature, thus on the efficiency of gears (in terms of power loss).Research limitations/implicationsStudied cases were limited to experimental gear models compliant to the FZG machine.Practical implicationsLow‐loss gears can be produced using common technologies and tools. Its design includes power loss minimization besides mechanical strength. The new gears are more environmentally friendly and can operate with lower power consumption, lower temperature, increasing gear and gear oil life.Originality/valueThis work contributes to the development of the “low‐loss gears” concept, adapting it to low‐cost manufacturing technologies. Finally, more efficient gears and gearboxes can be produced only by performing simple geometrical modifications to standard gears.
Adapting the Incredible Years child dinosaur social, emotional, and problem-solving intervention to address comorbid diagnoses
Authors: Webster-Stratton Carolyn , Reid M. 
Published: November 2014

Young children who are referred to mental health agencies because of oppositional defiant disorder (ODD) and conduct problems (CP) frequently have comorbid diagnoses or symptoms such as attention deficit disorder (ADD) with or without hyperactivity (ADHD), language/learning and developmental, or autism spectrum disorders. Research has shown that the Incredible Years Child Dinosaur programme offered to children with comorbid issues is successful at reducing behaviour problems and increasing social and emotional competence. This article examines ways in which this small group therapy programme is tailored to address the individual goals of each child so that the intervention is developmentally and therapeutically appropriate. It discusses group composition, as well as the importance of specific content and teaching methods for children with ADHD, academic and language delays and mild autism.

PurposeThis paper aims to describe a review and overview of the issue of developing guidance on implementing recovery and supporting organisational change, focused specifically on seeking to clarify the many different contributions that “lived experience” could make to training and workforce development.Design/methodology/approachThe particular focus of our workshop was to clarify the key issues in workforce development, training for a recovery‐focused service and the contribution of “lived experience”. A particular outcome was to emphasise the benefits of collaborative co‐working between people who use services and practitioners at all levels.FindingsA key element of our learning has been in valuing collaborative co‐working and the synergism of personal experience, professional training, research and evaluation.Originality/valueThe paper draws out what lessons have been learned already and sketches guidance for future practice and service development.
Preparing for collaborative working in mental health: an interprofessional education project with clinical psychology trainees and nursing students
Authors: Priest Helena , Roberts Paula , Dent Helen , Hunt Tom , Weston Dale , Chell Amy , Blincoe Christine , Armstrong Christine 
Published: November 2014

PurposeEffective interprofessional working is widely claimed to enhance service delivery, user satisfaction, and most importantly, clinical outcomes. Achieving this position is proving difficult. Research suggests that strategies to enhance interprofessional collaboration should begin at the earliest possible opportunity to prevent negative stereotypes from developing. This project was an attempt to develop effective interprofessional education (IPE) across staff groups who work in the mental health arena (mental health nursing students and clinical psychology trainees).Design/methodology/approachParticipants were whole cohorts of undergraduate mental health nursing students (n=11) in their second year of training (at the commencement of their “branch” programme), and trainees on the doctorate in clinical psychology (n=10) at the start of their first year of training. IPE sessions were facilitated by mental health nursing and clinical psychology academic staff and clinicians. Activities included creative group work and problem‐based learning. Seven sessions were delivered across over a 2 year period.FindingsQualitative and quantitative data from this two year project showed an increase in positive attitudes towards professionals from each profession over a two year period, though no overall improvement. Qualitative analysis of participant comments provided more encouraging support for improvement in attitudes, within the theme areas of teamwork and collaboration, professional identity, and roles and responsibilities. Overall, the project provided important information on building positive attitudes within the mental health workforce, while identifying challenges that need to be anticipated and addressed.Originality/valueFew studies have explored IPE in mental health contexts, especially in the pre‐qualification arena.
Across the little divide? Life histories of public and third sector “boundary crossers”
Authors: Lewis David 
Published: November 2014

PurposeOrganizational life and policy making is increasingly conceived in terms of a “three sector” model – public, private and “third”. The purpose of this research paper is to examine a little‐studied phenomenon that increasingly characterises societies in both the “developed” and the “developing” worlds. It aims to argue that these “sectors” have permeable boundaries, and that increasing numbers of activists and professionals operate across such boundaries, with important implications for policy and work.Design/methodology/approachThe research paper reports on a set of new ethnographic life‐work history data from the UK, Bangladesh and Philippines to explore experiences of people who cross between, or straddle, the third sector and the public sector.FindingsThe paper constructs a preliminary typology of boundary crosser archetypes for purposes of further analysis. This is based on motivations and levels of boundary crossing. Boundary crossing of this kind is linked with the concept of “work role transition”, and with the micro‐politics of policy contention.Practical implicationsThe paper concludes by suggesting that such work may offer new practical insights into strengthening the capacity of both third sector and government agencies.Originality/valueThe paper aims to be original in opening up this new topic for further discussion (and in particular problematizing the idea of sector boundaries), and through using the life history method to as part of organisational ethnography.
Studying development organizations – towards a culture of participation?
Authors: Vorhölter Julia 
Published: November 2014

PurposeThis article aims to provide new insights to current debates within the anthropology of (participatory) development by presenting a theoretically‐informed, ethnographic case study of a development organization in Pretoria, South Africa.Design/methodology/approachA theoretical framework is proposed which links recent debates on organizational culture and participatory development. It is based on a thorough review of the literature in these two fields of research as well as on empirical findings from the case study.FindingsThe article shows that organizational culture is a crucial factor in understanding the complexities and failures of participatory development that has hitherto been largely ignored by development analysts and practitioners. Three factors are discussed, which affect an organization's approach towards participation: the influence of professionalization on organizational culture and participation; development brokers as agents of participatory development; and value and mission statements as indicators of an organization's “participatory potential”. The analysis demonstrates that anthropologists need to critically engage with the complexities of development operations, which requires analyzing the concrete practices, (power) structures and institutional incorporations of different development organizations.Originality/valueThe strength and originality of the study lies in its systematic focus on the internal factors of an organization and how these affect the implementation of participatory development. The questions raised in this paper are relevant for further comparative studies of development organizations, particularly those who claim to follow a participatory approach.
On the beat: variations in the patrolling styles of the police officer
Authors: Ramshaw Pauline 
Published: November 2014

PurposeThis article seeks to look at the police officer on patrol. It aims to explore three categories of work undertaken during periods of un‐tasked patrol where officers can self‐direct their work.Design/methodology/approachInformed by empirical data from an ethnographic study of front line community policing in Britain, the categories of work are illustrated through the profile(s) of officer(s) whose actions best support each style.FindingsThe coming together of officers with different skills and the propensity to undertake different types of police work can broaden the community policing philosophy as well as the practice itself. While an expansive policing mandate can be used to justify and explain the pursuit of preferential areas of police work by the patrolling officer, findings also uncover evidence of the persistence of police practices and attitudes that alienate certain community groups.Research limitations/implicationsGiven the sustained popularity of localized policing models, further ethnographies are needed to broaden the analysis of patrol work particularly as additional research of this kind conducted with different groups of officers may well reveal evidence of different patrol styles.Practical implicationsIf the full potential of community policing is to be recognized then the police service needs to encourage front line officers to devise ways of learning about, making contact with, and working with, the diverse groups that comprise local communities. However, introducing new policies and working practices needs to be accompanied by attitudinal and behavioural change.Originality/valueThe paper presents a new and original set of patrolling styles of the police officer.
Acoustic reflection logging for open and cased holes
Authors: Markov M. , Markova I. , Jarillo G. Ronquillo 
Published: November 2014

ABSTRACTIn the present work, the waveforms of reflected wave sonic log for open and cased boreholes are calculated. Calculations are performed for a borehole containing an acoustic multipole source (monopole, dipole, or quadrupole). A reflected wave is more efficiently excited at resonant frequencies. These frequencies for all source types are close to the frequencies of oscillations of a fluid column located in an absolutely rigid hollow cylinder. It is shown that the acoustic reverberation is controlled by the acoustic impedance of the rock Z = Vp ρs for fixed parameters of the borehole fluid, where Vp is the compressional wave velocity in the rock, and ρs is the rock density. This result is correct for all types of acoustic sources (monopole, dipole, or quadrupole). Methods of the waveform processing for determining parameters characterizing the reflected wave are discussed.
Consequences of habitat change and resource selection specialization for population limitation in cavity‐nesting birds
Authors: Martin Thomas E. 
Published: November 2014

Summary

Resource selection specialization may increase vulnerability of populations to environmental change. One environmental change that may negatively impact some populations is the broad decline of quaking aspen Populus tremuloides, a preferred nest tree of cavity‐nesting organisms who are commonly limited by nest‐site availability. However, the long‐term consequences of this habitat change for cavity‐nesting bird populations are poorly studied.

I counted densities of woody plants and eight cavity‐nesting bird species over 29 years in 15 high‐elevation riparian drainages in Arizona, USA. I also studied nest‐tree use and specialization over time based on 4946 nests across species.

Aspen suffered a severe decline in availability over time, while understorey woody plants and canopy deciduous trees also declined. The decline of plants resulted from increased elk Cervus canadensis browsing linked to declining snowfall.

Woodpeckers exhibited very high specialization (>95% of nests) on aspen for nesting, and densities of all six species declined with aspen over time. Mountain chickadees Poecile gambeli and house wrens Troglodytes aedon exhibited increasingly less specialization on aspen. Chickadees strongly increased in density over time, despite a relatively high specialization on aspen. House wren densities declined moderately over time, but nest‐box addition experiments demonstrated that nest‐site availability was not limiting their population. House wren densities increased with understorey vegetation recovery in elk exclosures via increased generality of nest‐site use, demonstrating that the decline in understorey vegetation on the broader landscape was the cause of their population decline.

Synthesis and applications. Management should target species that specialize in resource selection on a declining resource. Species with greater resource selection generalization can reduce population impacts of environmental change. Resource generalization can allow a species like the wren to take advantage of habitat refuges, such as those provided by the elk exclosures. Yet, resource generalization cannot offset the negative impacts of broad‐scale declines in habitat quality on the landscape, as demonstrated by the general decline of wrens. Ultimately, aspen is an important habitat for biodiversity, and land management programmes that protect and aid recovery of aspen habitats may be critical.
