“We are not phobic but selective”: the older generation’s attitude towards using technology in workplace communications
Authors: Singh Vibhav 
Published: July 2014

Purpose
– The purpose of this paper is to study and understand the older generation’s attitude toward use of technology for workplace communications.

Design/methodology/approach
– In-depth interviews were conducted with the older generation employees of an Indian Oil and Gas Public Sector Undertakings. Data gathered from the interviews were then analyzed to draw broad themes.

Findings
– Although the older generation is aware of the importance of technology and has adequate knowledge of its use, they are reluctant to use it. The reluctance is not on account of techno-phobia; it is more in the nature of approach-avoidance.

Research limitations/implications
– Organizations and human resource managers should focus on addressing the mental block of the older generation regarding the use of technology.

Practical implications
– Reverse mentoring and formation of cross-generational teams can be used to alter older generation’s selective mindset in relation to technology.

Originality/value
– This paper discusses the role of technology in intergenerational communication in the Indian context.
Evaluating training and development in UK universities: staff perceptions
Authors: Robson Fiona , Mavin Sharon 
Published: July 2014

Purpose
– This paper aims to analyse individual experiences of learning evaluation in UK Higher Education Institutions (HEIs) and identify areas for improvement as part of an HEFCE LGM funded project.

Design/methodology/approach
– Eight focus groups were included in two universities with staff in similar roles. After transcription, the data were analysed using template analysis to identify and compare key themes from across both universities.

Findings
– The context of UK higher education is clearly important due to the diverse job roles and on-going sectoral changes. Three key themes emerged; first was a lack of clarity from the learners on learning evaluation. The second key theme centres on the format, method and timing of capturing evaluation data and the perception that a “one size fits all” approach is not appropriate. The third finding suggests that line managers do not currently fulfil their critical roles in the process.

Research limitations/implications
– Small number of research participants and a focus on two universities. In addition, participants were relying on their memories of past evaluation experiences.

Practical implications
– Ensuring learners understand reasons for evaluating their learning is important. HEIs should utilise a more diverse range of tools at the design stage to collect evaluation data. All stakeholder roles need to be clarified, and line managers require additional support.

Originality/value
– First, we address a gap in the existing sector-specific literature identified by Burgoyne et al. (2009) who contend that there is a lack of research in this area. Second, we contribute to the development of research in the journal by analysing evaluation from the perspective of the participants, and third, we offer recommendations for practice.
Spillover of diet changes on intentions to approach healthy food and avoid unhealthy food
Authors: Bech-Larsen Tino , Kazbare Laura 
Published: July 2014

Purpose– The purpose of this paper is to describe two exploratory studies of how experience (lacking, failed, or successful) of trying to implement healthy eating behaviours influences future intentions to maintain and expand such behaviours (so called “spillover”).Design/methodology/approach– The two survey-based (n=2,120) studies involved Danes aged 13-15 and 55-70 years, respectively.Findings– The studies showed that the self-reported experience of successfully increasing the intake of healthy (fruit and vegetables) and decreasing the intake of less healthy (soft drinks and animal fats) categories had spillover effects on the intention to pursue these behaviours in the future. For all the categories included, the intentions of the respondents who had tried and succeeded were significantly higher than those of the other respondents. The intentions of the group who had tried but failed were also significantly higher compared to those of the non-triers. Moreover, whether successful or not, both the experience of trying to increase the intake of healthy and to reduce the intake of less healthy food had a significant positive influence on the intention to try the opposite type of behaviour in the future. Healthy (fruit and vegetables) and decreasing the intake of less healthy (soft drinks and animal fats) categories had spillover effects on the intention to pursue these behaviours in the future. For all the categories included, the intentions of the respondents who had tried and succeeded were significantly higher than those of the other respondents. The intentions of the group who had tried but failed were also significantly higher compared to those of the non-triers. Moreover, whether successful or not, both the experience of trying to increase the intake of healthy and to reduce the intake of less healthy food had a significant positive influence on the intention to try the opposite type of behaviour in the future.Originality/value– As regards spillover between approach and avoidance behaviours related to healthy eating, only few studies have been published. The studies reported here contribute to the understanding of how experience with different types of healthy eating affect future intentions to change eating habits and provides insight for health promoters in their choice of which specific eating behaviours to address.
A systematic review investigating the use of Twitter and Facebook in university-based healthcare education
Authors: Smith Toby , Lambert Rodney 
Published: July 2014

Purpose
– The purpose of this paper is to evaluate the use, attitudes and perceptions of both teachers and students towards social media platforms (Facebook and Twitter) in healthcare higher education practice.

Design/methodology/approach
– Systematic literature review. A search of published and unpublished databases was conducted from January 2000 to January 2013. Data were synthesised through a narrative approach. All included studies were critically appraised using Critical Appraisal Skills Programme appraisal tools.

Findings
– From a total of 876 papers, 16 publications met the eligibility criteria. The review papers were largely of moderate methodological quality. The results indicated that Facebook and Twitter are perceived as potentially useful adjuncts in healthcare higher education practice. Their use as part of a “blended” approach to classroom teaching has been employed to enhance communication and increase accessibility of students to real-world practices and expertise. Whilst students perceive this to be of value, some have reservations regarding the possibility of faculty members spying or infringing on their “virtual” social community. Faculty members expressed some reservations regarding the perceived boundary between student-staff relationships.

Originality/value
– This is the first paper to systematically review the literature on the use of social media networking sites in health education. This identified both the potential strengths and weaknesses of using this new technology, and highlights areas to expand knowledge with further research and practice.
Parental participation in primary schools; the views of parents and children
Authors: O. John-Akinola Yetunde , Nic Gabhainn Saoirse 
Published: July 2014

Purpose
– Parental participation is important for strengthening and sustaining the concept of school health promotion but little is written on the processes involved. The purpose of this paper is to assess Irish parents’ and pupils’ views on how parents take part, or would like to take part, in school life.

Design/methodology/approach
– The sample was recruited from nine primary schools, three Health Promoting Schools and six matched schools. Pupils aged nine to 13 years in the 4th, 5th and 6th class groups participated in the study. Parents of all participating pupils were also invited to take part in the study. Data were collected by self-completion questionnaire, comprising three closed and one open question.

Findings
– A total of 218 parents and 231 pupils participated. There was general agreement between parents and pupils on parental participation in school. Overall 40.6 per cent of parents and 43.2 per cent of pupils reported that parents frequently take part in school activities. A majority of both parents (79.5 per cent) and pupils (83.6 per cent), agreed that parents were encouraged to talk about things that concern their child in school, while 73.5 per cent of parents and 65.6 per cent of pupils reported that they were made to feel a part of child's school. Qualitative data from parents and pupils suggested similar ways in which parents can best take part in school. Some respondents suggested how schools could engage with parents but most responses provided examples of how parents could act directly to take part in school life. These direct actions included doing, helping with, and watching school activities such as sports, tours, music and cake sales.

Originality/value
– The findings illustrate the similarity of views of parents and pupils concerning parents’ participation in school life and suggest that children may have the potential to represent the voice of their parents in school when considering how to improve parental participation in schools.
Application of the homotopy perturbation method to an inverse heat problem
Authors: Zhou Guanglu , Wu Boying 
Published: July 2014

Purpose
– The purpose of this paper is to present a general framework of Homotopy perturbation method (HPM) for analytic inverse heat source problems.

Design/methodology/approach
– The proposed numerical technique is based on HPM to determine a heat source in the parabolic heat equation using the usual conditions. Then this shows the pertinent features of the technique in inverse problems.

Findings
– Using this HPM, a rapid convergent sequence which tends to the exact solution of the problem can be obtained. And the HPM does not require the discretization of the inverse problems. So HPM is a powerful and efficient technique in finding exact and approximate solutions without dispersing the inverse problems.

Originality/value
– The essential idea of this method is to introduce a homotopy parameter p which takes values from 0 to 1. When p=0, the system of equations usually reduces to a sufficiently simplified form, which normally admits a rather simple solution. As p is gradually increased to 1, the system goes through a sequence of deformations, the solution for each of which is close to that at the previous stage of deformation.
Refined gray-encoded evolution algorithm for parameter optimization in convection-diffusion equations
Authors: Yang Xiaohua , Di Chongli , Mei Ying , Li Yu-Qi , Li Jian-Qiang 
Published: July 2014

Purpose
– The purpose of this paper is to reduce the computational burden and improve the precision of the parameter optimization in the convection-diffusion equation, a new algorithm, the refined gray-encoded evolution algorithm (RGEA), is proposed.

Design/methodology/approach
– In the new algorithm, the differential evolution algorithm (DEA) is introduced to refine the solutions and to improve the search efficiency in the evolution process; the rapid cycle operation is also introduced to accelerate the convergence rate. The authors apply this algorithm to parameter optimization in convection-diffusion equations.

Findings
– Two cases for parameter optimization in convection-diffusion equations are studied by using the new algorithm. The results indicate that the sum of absolute errors by the RGEA decreases from 74.14 to 99.29 percent and from 99.32 to 99.98 percent, respectively, compared to those by the gray-encoded genetic algorithm (GGA) and the DEA. And the RGEA has a faster convergent speed than does the GGA or DEA.

Research limitations/implications
– A more complete convergence analysis of the method is under investigation. The authors will also explore the possibility of adapting the method to identify the initial condition and boundary condition in high-dimension convection-diffusion equations.

Practical implications
– This paper will have an important impact on the applications of the parameter optimization in the field of environmental flow analysis.

Social implications
– This paper will have an important significance for a sustainable social development.

Originality/value
– The authors establish a new RGEA algorithm for parameter optimization in solving convection-diffusion equations. The application results make a valuable contribution to the parameter optimization in the field of environmental flow analysis.
Simulation of co-rotating vortices based on compressible vortex method
Authors: Huang Haiming , Huang Guo , Xu Xiaoliang , Li Weijie 
Published: July 2014

Purpose
– Relevant analyses are presented on the base of the compressible vortex method for simulating the development of two or three co-rotating vortices with different characteristic Mach numbers. The paper aims to discuss this issue.

Design/methodology/approach
– In addition to having vorticity and dilatation properties, the vortex particles also carry density, enthalpy, and entropy. Taking co-rotating vortices in two-dimensional unsteady compressible flow for an example, truncation of unbounded domains via a nonreflecting boundary condition was considered in order to make the method computationally efficient.

Findings
– For two identical vortices, the effect of the vortex Mach number on merging process is not evident; if two vortices have the same circulation rather than different radiuses, the vorticity and dilatation fields of the vortex under a vortex Mach number will be absorbed by the vortex under a higher vortex Mach number. For three vortices, if the original arrangement of the vortices is changed, the evolvement of the vorticity and dilatation fields is different.

Originality/value
– The paper reveals new mechanism of the three co-rotating vortices by a feasible compressible vortex method.

Authors: Song Weidong , Tang H.P. , Mao X.N. 
Published: July 2014

Purpose
– The purpose of this paper is to investigate tensile properties of TiC particle-reinforced titanium matrix composites (PRTMC) using the elasto-plastic finite element (FE) programs and the homogenization method and the fixed point iteration method.

Design/methodology/approach
– Two quasi-static and dynamic transient programs of elasto-plastic FE were coded by using FORTRAN. Based on the FE programs, the FE model of the TiC PRTMC with typical microstructures was established by using the fixed point iteration method and the homogenization theory. The hot deformation behavior of TiC PRTMC under different temperatures were analyzed by using the above model and programs.

Findings
– Calculation results are presented to investigate the influence of different temperatures on the hot deformation behavior of TiC PRTMC. Based on the experimental data, a good agreement was obtained between the numerical predictions and the experimental results, and the feasibility of this method was verified.

Originality/value
– The work is original and findings are new, which demonstrates this FE frame combined with the homogenization method and the fixed point iteration method can be used to investigate the tensile behavior of particle-reinforced metal matrix composites.
Analytical solutions to a fractional generalized two phase Lame-Clapeyron-Stefan problem
Authors: Li Xicheng 
Published: July 2014

Purpose
– The mathematical model of a two-phase Lamé-Clapeyron-Stefan problem for a semi-infinite material with a density jump is considered. The purpose of this paper is to study the analytical solutions of the models and show the performance of several parameters.

Design/methodology/approach
– To describe the heat conduction, the Caputo type time fractional heat conduction equation is used and a convective term is included since the changes in density give rise to motion of the liquid phase. The similarity variables are used to simplify the models.

Findings
– The analytical solutions describing the changes of temperature in both liquid and solid phases are obtained. For the solid phase, the solution is given in the Wright function form. While for the liquid phase, since the appearance of the advection term, an approximate solution in series form is given. Based on the solutions, the performance of the parameters is discussed in detail.

Originality/value
– From the point of view of mathematics, the moving boundary problems are nonlinear, so barely any analytical solutions for these problems can be obtained. Furthermore, there are many applications in which a material undergoes phase change, such as in melting, freezing, casting and cryosurgery.
Particle properties for suspension plasma spray
Authors: Lijuan Qian , Chu Xianyu 
Published: July 2014

Purpose
– The purpose of this paper is to use comprehensive model to investigate the effects of particle physical properties on in-flight nano-particles behavior for the radio frequency suspension plasma spray.

Design/methodology/approach
– In this paper, both the effects thermal properties of solvent and solid particle on the evolution of particle size, velocity and temperature are discussed. Besides, the numerical analysis is also conducted to investigate the influences of particle physical properties on the characteristic distributions of particles for poly-disperse cases.

Findings
– Results show the thermal properties of solvent have critical effects on the discharged point of the solid particles, but little influence on the final particle velocity and size, as well as their distributions. The final state of particle temperature is mainly determined by the solid particle thermal properties, especially depending on the boiling point.

Originality/value
– Most of the former studies took the experimental approaches and mainly focussed on the operating conditions effects. While beyond the operating conditions, the variety of particle physical and thermal properties also has strong effect on particle heating performance.
Numerical simulation of nanoparticles diffusion and coagulation in a twin-jet via a TEMOM method
Authors: Yin Zhaoqin , Liu Huijie 
Published: July 2014

Purpose– The purpose of this paper is to study nanoparticles diffusion and coagulation processes in a twin-jet.Design/methodology/approach– Large eddy simulation (LES) and Taylor-series expansion moment method (TEMOM) are employed to deal with a nanoparticle-laden twin-jet flow.Findings– The numerical results show that the interaction of the two jets and turbulence eddy structures rolling-up, paring and shedding in flow sharply affects particles number concentration. Particle diameter grows quickly at the interfaces of jets. Coagulation shows more obvious effect at initial stage than that in the subsequent period. Then diffusion makes the particle diameter distribution much more uniform.Originality/value– In recent years a great number of attentions have been focussed on the issue of particulate dynamics processes including diffusion, coagulation and deposition, etc. However, up to now few works have been focus on the nanoparticles coagulation and dispersion in turbulent flows. The investigation on the diffusion and coagulation process of nanoparticles using TEMOM in a twin-jet flow has not been found.

Authors: Bao Fubing , Mao Zhihong , Qiu Limin 
Published: July 2014

Purpose– The purpose of this paper is to investigate the gas flow characteristics in near wall region and the velocity slip phenomenon on the wall in nano-channels based on the molecular dynamics simulation.Design/methodology/approach– An external gravity force was employed to drive the flow. The density and velocity profiles across the channel, and the velocity slip on the wall were studied, considering different gas temperatures and gas-solid interaction strengths.Findings– The simulation results demonstrate that a single layer of gas molecules is adsorbed on wall surface. The density of adsorption layer increases with the decrease of gas temperature and with increase of interaction strength. The near wall region extents several molecular diameters away from the wall. The density profile is flatter at higher temperature and the velocity profile has the traditional parabolic shape. The velocity slip on the wall increases with the increase of temperature and with decrease of interaction strength linearly. The average velocity decreases with the increase of gas-solid interaction strength.Originality/value– This research presents gas flow characteristics in near wall region and the velocity slip phenomenon on the wall in nano-channels. Some interesting results in nano-scale channels are obtained.
