Influence of inter‐disc space on the turbulent flow between two rotating discs
Authors: Raddaoui Maher 
Published: April 2013

PurposeRotating flows are very important because they are found in industrial and domestic applications. For a good performance, it is important to dimension correctly the energy efficiency and the lifespan of the apparatuses while studying, for example, the influence of their physical and geometrical characteristics on the various hydrodynamic constraints, thermal and mechanics which they will support. The purpose of this paper is to describe experiments and a numerical study of the inter‐disc space effects on the mean and the turbulent characteristics of a Von Karman isotherm steady flow between counter‐rotating disks.Design/methodology/approachExperimental results are obtained by the laser Doppler anemometer technique performed at IRPHE (Institute of Research on the Phenomena out Equilibrium) in Marseille, France. The numerical predictions are based on one‐point statistical modeling using a low Reynolds number second‐order full stress transport closure (RSM model).FindingsIt was found that the level of radial velocity increases with the aspect ratio near to the axis of rotation but this phenomenon is reversed far from this zone; the level of tangential velocity, of turbulence kinetic energy and of the torsion are definitely higher for the largest aspect ratio. The best contribution of this work is, at the same time, the new experimental and numerical database giving the effect of the aspect ratio of the cavity on the intensity of turbulence for Von Karman flow between two counter rotating disks.Research limitations/implicationsThe limitation of this work is that it concerns rotating flows with very high speeds because the phenomena of instability appear and the application of this model for cavities of forms is not obvious.Practical implicationsThis work is of technological interest; it can be exploited by industrialists to optimize the operation of certain machines using this kind of flow. It can be exploited in the teaching of certain units of Masters courses: gathering experimental techniques; numerical methods; and theoretical knowledge.Social implicationsThis work can also have a social interest where this kind of simulation can be generalized with other types of flows responsible for certain phenomena of society, such as the phenomenon of pollution. This work can have a direct impact on everyday life by the exploitation of the rotary flows, such as being a very clean and very economic means to separate the undesirable components present in certain fluid effluents.Originality/valueThe best contribution of this work is the new experimental and numerical database giving the effect of the aspect ratio of the cavity on the intensity of turbulence for Von Karman flow between two counter rotating disks.

PurposeThe purpose of this paper is to obtain analytic solutions of the (1+1) and (2+1)‐dimensional dispersive long wave equations by the homotopy analysis and the homotopy Padé methods.Design/methodology/approachThe obtained approximation by using homotopy method contains an auxiliary parameter which is a simple way to control and adjust the convergence region and rate of solution series.FindingsThe approximation solutions by [m,m] homotopy Padé technique is often independent of auxiliary parameter ℏ and this technique accelerates the convergence of the related series.Originality/valueIn this paper, analytic solutions of the (1+1) and (2+1)‐dimensional dispersive long wave equations are obtained by the homotopy analysis and the homotopy Padé methods.

Practitioner understanding of value in the UK building sector
Authors: Thomson Derek S. , Austin Simon A. , Mills Grant R. , Devine‐Wright Hannah 
Published: April 2013

PurposeFor over a decade, UK public sector construction policy and industry rhetoric has advanced a value agenda that advocates the development of project‐specific understanding of value. This study aims to examine construction practitioners’ collective cognition of value to determine how their facilitation may bias this intent. A value continuum is contributed.Design/methodology/approachCritique of the design quality indicator (the primary value agenda instrument) finds that it overemphasises objective value, confirming the need for practitioners to help stakeholders develop broader understanding of value. The freelisting technique of cultural anthropology is adopted to model practitioners’ collective cognition of value and, thus, their bias over this process. The standard freelisting protocol is followed.FindingsPractitioners’ collective understanding is found to comprise related concepts that resolve to a one dimensional “value continuum” with subjective and objective terminals and which fully embodies value agenda intent. In contrast, the concepts articulated by the design quality indicator are biased towards the objective value continuum terminal, confirming the need for practitioners to facilitate stakeholder exploration of the full continuum if the value agenda is to be fully addressed.Research limitations/implicationsThe value continuum only reflects the views of a small but typical sample of construction practitioners. Further work must characterise model completeness and consistency through the supply chain.Originality/valueThis is the first work to derive an empirical model of construction practitioners’ collective understanding of value. It achieves this by the novel linking of a cognitive modelling technique from cultural anthropology with an emic interpretation of the results.
The social life of the novel idea: what did social psychologists ever do for us?
Authors: Barrett Jennifer , Goulding Jack , Qualter Pamela 
Published: April 2013

PurposeThe purpose of this paper is to present the extant literature relating to the social processes of innovation in built environment design teams. The paper connects the relevant and significant work in the field of social psychology and architecture, engineering and construction (AEC) to derive a theoretical framework which can be used to direct further research, towards development of the behavioural facet of design management.Design/methodology/approachFirst, the paper establishes which aspects of social processes of innovation are already present within the AEC field and examine concepts/ideas in social psychology that are likely to be important in understanding group processes within AEC, applying three emergent themes of social climate; risk attitudes and motivation and reward. Second, the paper identifies which elements of social psychology may be used to expand, consolidate and develop our understanding and identify gaps in AEC specific knowledge.FindingsThe paper suggests that whilst the AEC literature has supplanted some key elements of social psychology, this discipline offers a further and significant theoretical resource. However, whilst some aspects of social climate and motivation/reward are well‐represented in the AEC field, these have not yet been fully explored. Furthermore, how collective attitudes to risk can influence design decision‐making is identified as having a limited presence.Originality/valueThis paper is the first to bring together the two disciplines of AEC and social psychology to examine the social aspects of innovative design performance in built environment teams. The paper fulfils an identified need to examine the social processes that influence innovative design performance in construction
Reflective practice in a capstone business internship subject
Authors: Lang Roselynn , McNaught Keith 
Published: April 2013

PurposeCapstone subjects which link students approaching graduation with significant experiential learning and relevant industry placements, have the potential to be very valuable to students. This is particularly evident if they are able to critically reflect on the experience. In light of this, the School of Business at the University of Notre Dame Australia, Fremantle campus, sought to embed reflective practice and reflective writing within its Business Internship (capstone) subject. This paper aims to discuss this.Design/methodology/approachThe paper presents a case study approach.FindingsSignificant challenges emerged in relation to the student learning experience. Some students did not perceive the value of an internship, or of engaging in a professionally reflective process. Business students' differing academic literacy standards became apparent, as did the diverse experiences of international students. It became evident that students required explicit teaching and more thorough training to understand the value of reflection and to write reflectively where required. Subsequently, reflective writing workshops were trialled and embedded in the subject. Reflective practice enabled students to move to a deeper level of understanding, rather than submitting a superficial retelling of their internship experience.Originality/valueThe value of reflective writing is widely recognised in many disciplines, although its application in Business capstone subjects is relatively new. This merits further scholarship, particularly as capstone subjects are increasingly being used to demonstrate assurance of learning for accrediting agencies in Australia.

Published: April 2013

PurposeAchieving quality standards in postgraduate education, particularly among Higher Degree by Research (HDR) students, can be challenging. In addition to the diverse educational and cultural backgrounds of these students, thesis writing frequently involves the development of new skills associated with the comprehension of a large volume of information, critical analysis and the development of an academic writing style. Many students need support in one or all of these key areas. Universities currently provide a number of different writing support activities to address students' needs. The purpose of this study is to report on a writing support intervention that employed a specialist in academic writing to support HDR students in the business faculty.Design/methodology/approachFollowing a two‐year period, the intervention was evaluated to assess the appropriateness and effectiveness of this support using qualitative methods. The results of this study are presented and discussed from different angles. First, a lecturer in academic writing support outlines her observations and reflection on the value of individual consultations and students' progress. Second, the attitudes and experience of students and their supervisors to this service are discussed. This is followed by the faculty senior management view with regard to the effectiveness and efficiency of this service.FindingsThis research found that both students and their supervisors expressed satisfaction with the service offered. Also it was found that the writing quality of submitted theses is improving; the costs of thesis editing have reduced; HDR students appear to be more satisfied with and confident of their academic writing; the attractiveness of the PhD program has been enhanced, as judged by the increase in PhD enquiries and the quality of potential applicants.Research limitations/implicationsThe results reported here indicate that the intervention was successful. However, the sample size was relatively small and the HDR candidates and supervisors were drawn from only one faculty in one university.Practical implicationsThe study provides some recommendations that could be taken into account by senior management and academic staff in order to set up and deliver a faculty‐based writing support service for HDR students, which would bring benefits to students, their supervisors, faculties and universities.Originality/valueThe value of this research is that the writing program was proven to be beneficial for universities to support research students in the development of their writing skills, which in turn, could improve the quality of thesis and ensure on time completion.
State Rescaling in Non‐Western Contexts
Authors: Park Bae‐Gyoon 
Published: April 2013

AbstractState rescaling is the subject of a continuously growing literature that provides valuable insights into our current understandings of globalization, the spatiality of the capitalist state and urban and regional development. There have been, however, growing concerns about the wider applicability of this literature. Since the bulk of state rescaling studies have focused on North American and European examples, the existing literature is limited in its conceptualization of the diverse and concrete ways in which the spatial and scalar restructuring of capitalist states takes place in different historical, political and social contexts beyond North America and Western Europe. This symposium provides the literature with a valuable opportunity to transcend this limitation. The articles in this collection discuss the processes of state rescaling in non‐Western countries such as Japan, Korea, Brazil and Turkey. By providing detailed explanations of state rescaling and the associated politico‐economic processes in non‐Western countries and regions, they not only show that state‐rescaling literature is more widely applicable and meaningful beyond Western politico‐economic contexts, but also point out what is missing in the existing corpus.
In‐training assessment developments in postgraduate education in Europe
Authors: van der Vleuten Cees , Verhoeven Bas 
Published: April 2013

AbstractAimThis paper reviews changes that are underway in postgraduate medical education in various European countries. Training in the workplace is a very effective way of learning, but it has many imperfections. Changes in in‐training assessment are proposed to remedy some of these.Assessment toolsThe focus is on a set of assessment tools for performance in authentic work‐based contexts. These tools include direct performance measures of single clinical events (mini‐Clinical Evaluation Exercise, Direct Observation of Practical Skills, Objective Structured Assessment of Technical Skills, Case‐based Discussion, Mini‐Peer Assessment Tool) and performance measures over a period of time (Multi‐Source Feedback), based on judgement by one or more knowledgeable assessors (supervisor, other healthcare professional, patient, trainee himself/herself). Quantitative and qualitative information from single assessments is first and foremost used to promote learning, but also aggregated across a large sample of contexts and assessors in order to obtain an overall picture of a trainee's progress. Aggregating instruments, such as the portfolio, can be used to collect, support and assess outcomes in terms of competencies achieved. We will describe this set of instruments and provide theoretical background as well as our own practical experiences.DiscussionA central message is that the utility of assessment methods lies very much in the (understanding of) the users. Therefore, our concern is more with the actual implementation of change than with the assessment technology per se. If we fail in our efforts to implement real change, postgraduate education may be at risk for bureaucratization and trivialization. We nevertheless are excited to see change happening in the right direction, but remain patient, not expecting very quick wins.

SummaryAlternative splicing is associated with human disease. In acute promyelocytic leukaemia (APL) patients with the long (L)‐type promyelocytic leukaemia‐retinoic acid receptor α fusion gene (PML‐RARA), three alternative splicing isoforms can be detected: E5(+)E6(+), E5(−)E6(+), and E5(−)E6(−). This study is the first to demonstrate that alternative splicing of L‐type PML‐RARA is associated with time to achieve complete remission (CR) in APL. Higher expression of the E5(−)E6(−) isoform, the short isoform, was related to longer time to achieve CR. Each isoform was constructed into recombinant lentiviral vector and transfected into U937 cells. Compared with the E5(−)E6(+) and E5(+)E6(+) groups, the U937 cells with E5(−)E6(−) showed lower sensitivity to all‐trans‐retinoic acid treatment.

ObjectiveTo compare the efficacies of a thermosensitive poloxamer (TPX) and Merogel in preventing adhesion applied after the removal of nasal packing in endoscopic sinus surgery as a non‐inferiority trial.DesignRandomised, multicentre, single‐blind, active‐controlled, matched‐pair study.SettingYonsei University Gangnam Severance Hospital, Korea University Guro Hospital.ParticipantsA total of 70 patients were enroled and underwent endoscopic sinus surgeries. Four of the patients did not complete their follow‐up. Analysis of the 66 enroled patients having completed postoperative assessment was performed. The severity of rhinosinusitis was graded with a Lund‐McKay CT score, and only those with bilateral disease and a CT score difference ≤2 between sinuses were included.Main outcome measuresAn independent rhinologist from a third institution through a blinded assessment with digital photoendoscopy of the middle meati bilaterally taken postoperatively.ResultsIn the blinded assessment, thermosensitive poloxamer (anti‐adhesion rate: 92%) was similar to Merogel (anti‐adhesion rate: 89%). Evaluation of the presence and grade of adhesion, oedema, and infection in the middle meatus revealed no significant differences between the thermosensitive poloxamer group and the Merogel group at all postoperative periods.ConclusionAnti‐adhesive effects of thermosensitive poloxamer are similar to those of Merogel. Therefore, thermosensitive poloxamer can be considered a safe alternative to Merogel for preventing adhesion in patients undergoing endoscopic sinus surgeries, and further evaluation of thermosensitive poloxamer as an anti‐adhesive and primary packing material compared with the control using no packing is needed.
Experimental and analytical assessment of fatigue and crack propagation in cold worked open hole specimens
Authors: Boni L. , Fanteria D. , Lanciotti A. , Polese C. 
Published: April 2013

ABSTRACTFatigue and crack propagation tests are carried out on 7075‐T73 open hole aluminium alloy specimens. A remarkable increment of fatigue life due to the Split Sleeve Cold ExpansionTM process is observed, further improved by applying the process twice on the same hole. Comparable increments are obtained by using the StressWaveTM method. Specific tests are performed in order to point out a possible relaxation of the residual stresses due to fatigue loading. The results obtained reveal no relaxation phenomena in the tested specimens.The compressive residual stress around cold expanded holes is numerically evaluated. Dedicated experiments based on the Sachs method are conducted to confirm the residual stress prediction.
An estimate of the global sink for nitrous oxide in soils
Authors: Schlesinger William H. 
Published: April 2013

AbstractA literature survey of studies reporting nitrous oxide uptake in the soils of natural ecosystems is used to suggest that the median uptake potential is 4 μg m−2 h−1. The highest values are nearly all associated with soils of wetland and peatland ecosystems. Globally, the consumption of nitrous oxide in soils is not likely to exceed 0.3 TgN yr−1, indicating that the projected sink is not more than 2% of current estimated sources of N2O in the atmosphere.

Published: April 2013

A novel solution combustion method has been used to prepare Mg‐Mn ferrites of various compositions, Mg0.9Mn0.1Fe1‐xO4 where x = 0.2, 0.4, 0.6, 0.8, and the properties were investigated in the present work. Nano‐size Mg‐Mn ferrite particles with diameter in the range of 8~ 15 nm were successfully formed via this method. The combustion temperature of the oxidation‐reduction was apparently occurred at 200°C. The result of X‐ray diffraction (XRD) analysis indicated that the as‐burnt powder affords a pure single spinel ferrite phase at low temperature. The thermal analysis of nitrate–citrate gels was characterized by DTA‐TG. The TEM and SEM observations give the morphology and microstructure of the products. The dielectric properties of the sintered Mg‐Mn ferrites were investigated by using HP/Agilent 4291B RF impedence/material analyzer. It was found that there was no maximum dielectric loss within the measured frequency range until 1 GHz due to excellent compositional control in this method.

Two different specific surface area of starting BaCO3, 10 and 30 m2/g, are used to prepare solid‐state BaTiO3 powder. Pure tetragonal BaTiO3 was obtained at a lower calcination temperature with smaller BaCO3, and the kinetic calculations of activation energy also agree with it. A clear, thin, and nano‐sized cubic BaTiO3 clusters on TiO2 particles were also observed. A narrower particle size distribution of BaTiO3 powder (350 nm) was obtained from 30 m2/g of starting BaCO3 at 1000°C. After sintering with reducing atmosphere, the ceramics with potential of X8R or X7R specifications and a clear core–shell microstructure were obtained in this study.
Supersize my identity: when thoughts of contracting swine flu boost one's patriotic identity
Authors: Bélanger Jocelyn J. , Faber Tim , Gelfand Michele J. 
Published: April 2013

AbstractPandemics are socially threatening situations that rapidly spread across large regions. Thinking of contracting dangerous diseases can potentially evoke fear and death‐related thoughts. The aim of the present work was to investigate how individuals respond to fear associated with contracting a pandemic disease (i.e., swine flu). In accordance with the mortality salience hypothesis of terror management theory (Greenberg, Pyszczynski, & Solomon, 1986), we predicted that individuals concerned with contracting swine flu would demonstrate greater investment in cultural worldviews (i.e., patriotism) in response to death anxiety. The implications of these findings for understanding global issues in domains related to health and politics are discussed.
