Impact of externalities on sustainable development: evidence from public-private partnerships in Kazakhstan and Russia
Authors: Mouraviev Nikolai , Kakabadse Nada 
Published: November 2014

Purpose
– This paper aims to investigate the influence of public-private partnerships (PPPs) on social and economic conditions in Kazakhstan and Russia from a public economics perspective, namely, through the lens of a market failure and PPPs’ negative externalities.

Design/methodology/approach
– Drawing on the concept of a market failure and using the externalities perspective, the paper investigates whether partnerships are instrumental in solving market problems, which is illustrated by the evidence from ongoing PPP projects in Kazakhstan and Russia.

Findings
– Results show that citizens face expansion of monopolistic trends in the service provision and decreased availability of public services. Additionally, the government support to partnerships recreates a negative externality in the form of a higher risk premium on loan interest rates that banks use to finance PPPs. The partnerships’ impact on sustainable development often appears detrimental, as they significantly intensify the struggle between sub-national governments for increased transfers from the national budget.

Practical implications
– The government agencies must incorporate the appraisal of the PPP externalities and their effects on the society in the decision-making regarding the PPP formation.

Originality/value
– The authors suggest that, although government is interested in PPPs’ positive externalities, in reality many negative externalities may offset the positive spillover effects. As a result, the partnerships’ contributions to economic and social sustainability remain controversial. Extending the value-for-money concept to incorporate the assessment of PPP externalities might significantly enhance the partnership conceptualisation by more comprehensive and accurate assessment of PPPs’ economic and social value.
Diversity leadership under race-neutral policies in higher education
Authors: Jones Sosanya Marie 
Published: November 2014

Purpose
– The purpose of this paper is to gain insight about the experience of multicultural administrators who oversee bridge program designed to recruit and retain historically underrepresented students of color. The study was also designed to capture the experience of the multicultural administrator as well as what meaning they made of their role as a diversity leader, and the challenges they face as they try to meet diversity goals under the constraints of race neutrality.

Design/methodology/approach
– This is a descriptive qualitative multi-case study. In order to gain a better understanding of the experience of multicultural administrators as they try to enact diversity leadership under race-neutral policies a qualitative phenomenological multi-case designed was used. Semi-structured interviews were conducted with multicultural administrators from four institutions within a southern state of the USA.

Findings
– Data reveals that seeking to increase and foster diversity on predominantly white campuses under race neutrality is challenging. Many of the administrators expressed concern about how they would maintain and increase diversity and campus inclusiveness without specifically marketing and targeting to groups that are traditionally marginalized. Overall, they described the experience as one filled with heightened awareness of the social and political environment and how senior-level administrators and other offices on campus perceived them and their work.

Research limitations/implications
– Using a qualitative multi-case study limits generalizability. Also, there are many other factors such as institutional type, location, student population, and institutional capacity that may impact the institutional conditions in which each of these administrators work.

Practical implications
– The findings of this study can be used to inform institutional policy makers of these struggles as well as provide campus administrators and staff helpful recommendations for dealing with the politics of race neutrality as they continue to fulfill their responsibility to increase diversity on their campuses.

Social implications
– This paper may raise awareness about the challenges of employing race neutrality, particularly for states and institutions concerned with diversifying higher education. It also highlights the challenges leaders face when dealing with reduced funding and policies that do not support their work.

Originality/value
– The paper discusses an understudied and under-recognized group of diversity leaders dealing with a current race-neutral policies. It will be of interests to institutional leaders, multicultural administrators, and other types of diversity leaders in higher education.
Accountability and the rise of “play safe” pedagogical practices
Authors: Bailey Gillian 
Published: November 2014

Purpose
– The purpose of this paper is to examine how the culture of teacher accountability has been intensified in further education (FE) under neo-liberalist policy, with the result that the student-teacher relationship has shifted to one of supplier-consumer. The paper focuses on the impact which this shift has had on teachers’ pedagogical practice and employment prospects.

Design/methodology/approach
– The paper draws on data gathered during a three-year ethnographic study which focused on the experiences of trainee and newly qualified teachers working in the FE sector. The data were generated from naturally occurring evidence including reflective diaries, lesson observations and class discussions.

Findings
– The findings suggest that target-driven college cultures are creating conditions which encourage teachers to “play safe” in terms of pedagogical practice whilst students are becoming increasingly dependent on teacher-led direction in a bid to achieve targets. Not only are teachers being held increasingly accountable for their students’ results but their employment prospects are also dependent on them.

Research limitations/implications
– Although based on a small-scale study, the findings are of sufficient significance to stimulate debate and future research around the issue of how neo-liberalist policy impacts on practice in FE.

Practical implications
– The paper suggests that for both FE teachers and their students, creative thinking and experimentation may be at risk from the impact of such policy.

Originality/value
– This paper goes beyond existing critiques of accountability: it argues that as teachers’ employment prospects become increasingly dependent on student results, both teachers and their students are vulnerable to focusing on risk-free practices which jeopardise the potential for innovation and autonomy.
Sustainability of community engagement – in the hands of stakeholders?
Authors: Ramachandra Anubama , Naha Abu Mansor Nur 
Published: November 2014

Purpose
– The current gap in the field of community engagement is evaluation and measurement of the impacts on the stakeholders, mainly the community being engaged with. The paper aims to discuss these issues.

Design/methodology/approach
– This paper discusses the need to consider the stakeholder's perspective and their involvement in a community engagement initiative, or in any social program. The authors begin by debating the most common evaluation techniques used, followed by re-introducing stakeholder evaluation to the field of community engagement.

Findings
– The evaluation using the stakeholders’ approach will not only create a holistic evaluation process, but will also assist in fostering a sense of ownership of the community engagement program.

Originality/value
– Community engagement is given much importance nowadays in Malaysia, especially in line with institutes of higher learning's tripartite mission, the third mission being the ability to engage with communities. It is not surprising because community engagement offers enormous benefits for regional and societal development. Community engagement relies heavily on partnership and mutual reciprocity between different stakeholders such as communities, universities, non-government organizations, field experts and funding organizations. In order to sustain the engagement initiatives, it is important to know who are the “owners” or stakeholders of the program.

Authors: Xu Lan , Liu HongYing , Si Na , Wai Ming Lee Eric 
Published: November 2014

Purpose
– An electrospinning process is a multi-phase and multi-physics process. The purpose of this paper is to numerically simulate the two-phase flow in the electrospinning process. The numerical results can offer in-depth insight into physical understanding of many complex phenomena which cannot be fully explained experimentally.

Design/methodology/approach
– The two-phase flow can be calculated by solving the modified Navier-Stokes equations under the influence of electric field and the interface between the two fluids has been determined by using the Volume of Fluids (VOF) method. A realizable k-e model is used to model the turbulent viscosity. The numerical results can be obtained using Computational Fluid Dynamics (CFD) techniques.

Findings
– The numerical simulation is a powerful tool to controlling over electrospinning parameters such as voltage, flow rate, and others.

Research limitations/implications
– The numerical simulation of two-phase flow model will take into account solvent evaporation and solidification of the jet, which play pivotal roles in determining the internal fiber morphology of the jet to be described here.

Originality/value
– This paper deals with studying numerically the two-phase flow in the electrospinning process by applying CFD techniques. And the flow is modeled by ANSYS(FLUENT) using the VOF model.
Natural convection inside a C-shaped nanofluid-filled enclosure with localized heat sources
Authors: Mansour M.A. , Bakeir M.A. , Chamkha A. 
Published: November 2014

Purpose
– The purpose of this paper is to investigate natural convection fluid flow and heat transfer inside C-shaped enclosures filled with Cu-Water nanofluid numerically using the finite difference method.

Design/methodology/approach
– In this investigation, the finite difference method is employed to solve the governing equations with the boundary conditions. Central difference quotients were used to approximate the second derivatives in both the X and Y directions. Then, the obtained discretized equations are solved using a Gauss-Seidel iteration technique.

Findings
– It was found from the obtained results that the mean Nusselt number increased with increase in Rayleigh number and volume fraction of Cu nanoparticles regardless aspect ratio of the enclosure. Moreover the obtained results showed that the rate of heat transfer increased with decreasing the aspect ratio of the cavity. Also, it was found that the rate of heat transfer increased with increase in nanoparticles volume fraction. Also at low Rayleigh numbers, the effect of Cu nanoparticles on enhancement of heat transfer for narrow enclosures was more than that for wide enclosures.

Originality/value
– This paper is relatively original for considering C-shaped cavity with nanofluids.
Numerical simulation of flow through an eccentric annulus with heat transfer
Authors: K. Chauhan Amit , Prasad B.V.S.S.S. , Patnaik B.S.V. 
Published: November 2014

Purpose
– The purpose of this paper is to investigate the effect of narrow gap on the fluid flow and heat transfer through an eccentric annular region is numerically. Flow through an eccentric annular geometry is a model problem of practical interest.

Design/methodology/approach
– The approach involves standard finite volume-based SIMPLE scheme. The numerical simulations cover the practically relevant Reynolds number range of 104-106.

Findings
– In the narrow gap region, temperature shoot up was observed due to flow maldistribution with an attendant reduction in the heat removal from the wall surfaces. CFD analysis is presented with the aid of, streamlines, isotherms, axial velocity contours, etc. The engineering parameters of interest such as, Nusselt number, wall shear stress, etc., is presented to study the effect of eccentricity and radius ratio.

Research limitations/implications
– The present investigation is a simplified model for the rod bundle heat transfer studies. However, the detailed study of sectorial mass flux distribution is a useful precursor to the thermal hydraulics of rod bundles.

Practical implications
– For nuclear reactor fuel rods, the effect of eccentricity is going to be detrimental and might lead to the condition of critical heat flux. A thorough sub-channel analysis is very useful.

Social implications
– Nuclear safety standards require answers to a wide a range of what-if type hypothetical scenarios to enable preparedness. This study is a highly simplified model and a first step in that direction.

Originality/value
– The narrow gap region has been systematically investigated for the first time. A detailed sectorial analysis reveals that, flow maldistribution and the attendant temperature shoot up in the narrow gap region is detrimental to the safe operation.
A general finite volume based numerical algorithm for hydrocarbon reservoir simulation using blackoil model
Authors: Mosharaf Dehkordi Mehdi , T. Manzari Mehrdad , Ghafouri H. , Fatehi R. 
Published: November 2014

Purpose– The purpose of this paper is to present a detailed algorithm for simulating three-dimensional hydrocarbon reservoirs using the blackoil model.Design/methodology/approach– The numerical algorithm uses a cell-centred structured grid finite volume method. The blackoil formulation is written in a way that an Implicit Pressure Explicit Saturation approach can be used. The flow field is obtained by solving a general gas pressure equation derived by manipulating the governing equations. All possible variations of the pressure equation coefficients are given for different reservoir conditions. Key computational details including treatment of non-linear terms, expansion of accumulation terms, transitions from under-saturated to saturated states and vice versa, high gas injection rates, evolution of gas in the oil production wells and adaptive time-stepping procedures are elaborated.Findings– It was shown that using a proper linearization method, less computational difficulties occur especially when free gas is released with high rates. The computational performance of the proposed algorithm is assessed by solving the first SPE comparative study problem with both constant and variable bubble point conditions.Research limitations/implications– While discretization is performed and implemented for unstructured grids, the numerical results are presented only for structured grids, as expected, the accuracy of numerical results are best for structured grids. Also, the reservoir is assumed to be non-fractured.Practical implications– The proposed algorithm can be efficiently used for simulating a wide range of practical problems wherever blackoil model is applicable.Originality/value– A complete and detailed description of ingredients of an efficient finite volume-based algorithm for simulating blackoil flows in hydrocarbon reservoirs is presented.
How to influence hospitality employee perceptions on hotel brand performance?
Authors: Cheung Catherine , Kong Haiyan , Song Haiyan 
Published: November 2014

Purpose– This paper aims to understand employees’ perceptions of human resources management functions and how these affect brand performance, and the indirect influence of human resources management functions when mediated by job satisfaction in branded hotels in China. Hotel human resources functions, specifically organizational career management, and internal branding in hotels in mainland China were examined. The mediating effect of job satisfaction on the relationship between organizational career management and internal branding on brand performance was also examined.Design/methodology/approach– A survey of hotel supervisors and middle managers in mainland China yielded 510 valid questionnaires for data analysis. Structural equation modeling was used to empirically test the relationships between human resources management functions (organizational career management, internal branding and job satisfaction) and brand performance in four- and five-star hotels in China.Findings– The structural equation modeling results showed strong support for the mediating effect of job satisfaction on the relationships between organizational career management, internal branding and brand performance. Interestingly, although internal branding significantly affected brand performance, organizational career management alone did not.Research limitations/implications– The main limitation was the use of a convenience sampling method, which means respondents may not represent a sufficiently broad sample of hotel employees. Future studies are encouraged to explore internal branding and hotel career management using a probability sampling method.Practical implications– The findings offer new insights and directions for hotel human resources managers to improve brand performance, either through promoting internal branding itself, or by enhancing organizational career management, internal branding and employees’ job satisfaction to achieve brand performance.Originality/value– This is the first empirical study to analyze hotel management employees’ perceptions of the relationships between hotel human resources management, employees’ job satisfaction and hotel brand performance in China. The findings demonstrate the usefulness of applying human resources management functions to hotel branding.
What caused the decrease in RevPAR during the recession?
Authors: Zheng Tianshu 
Published: November 2014

Purpose
– This study aims to attempt to examine whether the increase in hotel room capacity in the USA had a significant impact on nationwide aggregated weekly revenue per available room (RevPAR) during the recession of 2007-2009 and forecast average RevPAR, Occupancy and Average Daily Rate (ADR) for 2013 and 2014.

Design/methodology/approach
– Using Autoregressive Integrated Moving Average with Intervention analysis technique, this study examined the significance of the fluctuations in weekly RevPAR, room capacity and market demand through the recent recession and forecasted hotel performance for 2013 and 2014.

Findings
– The results of time series analysis suggest that the fast growth of room capacity during the recession was one of the main causes of the decrease in RevPAR. The 9,878 more than expected increase in average weekly number of rooms probably caused at least $0.10 more than expected decrease in average weekly RevPAR. The findings of this study also suggest that the US lodging industry has been facing more severe oversupply since the recession and fully rebound of RevPAR cannot be expected in the very near future.

Practical implications
– The findings of this study will help stakeholders make more informed decisions to cope with possible future economic downturns. By quantifying the capacity increase and forecasting future market demand, this study provides hotel investors with empirical evidence on the overdevelopment and insights into expected overall hotel performance in next two years. This study has also discussed the cyclical patterns of hotel development during the past two recessions.

Originality/value
– By identifying overdevelopment as one of the main causes of RevPAR decrease during the recession, this study contributes to the literature by adding an alternative explanation of RevPAR fluctuations and deepens the understanding of the adverse effects overdevelopment has on the lodging industry. The findings of this study will help hotel investors develop more informed future expansion plans.
Does standardized service fit all?
Authors: Lai John , S. Lui Steven , H.Y. Hon Alice 
Published: November 2014

Purpose– The purpose of this paper is to explore the nature of the novel service encounter with reference to three research questions: first, what kind of creative acts do frontline employees undertake during a novel service encounter? Second, how does the novel service encounter correlate with service innovation? Third, how does it vary in different market environments? The novel service encounter refers to creative acts undertaken by frontline staff working at the employee-customer interface. These acts are important sources of new ideas for service innovation and demand systematic study.Design/methodology/approach– Methods in this study are triangulated by combining interviews, field observations and a survey to develop an observation template for examining the creative acts undertaken by frontline employees during service encounters in an international tourist apparel retailer.Findings– This paper provides initial empirical evidence of the process of the novel service encounter and highlights the use of participant observation as a useful methodology.Originality/value– This paper contributes to the service innovation literature by examining the novel service encounter using an observation template that takes into account its process-driven nature. It is suggested that improvisation by frontline employees during the service encounter is crucial to innovation, and a standardized service does not fit every situation.
Hotel innovation and performance in times of crisis
Authors: Campo Sara , M. Díaz Ana , J. Yagüe María 
Published: November 2014

Purpose– This paper aims to analyze the influence of innovation-based orientation on hotel performance, how the management’s perception of market turbulence moderates this relationship and the effect of an atmosphere of crisis.Design/methodology/approach– The research carried out used an on-line survey among four-star hotel managers in 52 Spanish cities.Findings– The results obtained indicate that the tendency of a hotel to innovate does not contribute directly and positively on short-term performance. However, it does confirm its importance when improving hotel performance in the medium- and long-term. This work discusses how the perception of technological turbulence influences the willingness to innovate, together with the effect that an economic-crisis-related-pessimistic management view has on marketing performance and long-term results.Originality/value– Reliable and valid scales, applicable to the hotel sector and useful both for researchers and managers, are provided to measure the tendency to innovate, perceived technological turbulence and company performance. Knowledge regarding innovation is expanded, including a critical factor to increase business profits and competitiveness in uncertain environments. The model proposed is tested in a sector where there is little empirical evidence about the effect of innovation on performance.
