Abstract
As the global economy expands, it would seem to be in the interests of the major professional sport leagues of the US to move into new markets, especially China, one of the fastest growing and largest in the world. In order to sell effectively in this market, it is vital to gain an understanding of the potential fan base. To explore national differences in fandom, a survey was completed by sports fans in both China and the US to assess which sports participants followed and which media they used, to identify fan motives and their feelings about expansion. This study determined that there are clear differences between Chinese and Americans. While many of the Chinese were fans of American sports, they tended to follow individual athletes rather than teams and had relatively low fan identity but high levels of fan motivation. Motives also varied by country, with aesthetics and affiliation the primary motives among the Chinese sample. These distinctions can be utilised to create marketing strategies.

Abstract
Purpose
Sustainable property development has increased in market share over the past two to three years globally and locally. This research aims to analyze the drivers and barriers to sustainable property development in Melbourne using the triple bottom line (TBL) theoretical framework. The TBL posits that sustainability has social, economic and environmental aspects to fulfil.
Design/methodology/approach
A questionnaire was sent out to 190 developers in Melbourne who promoted sustainable property development to ascertain their views about the drivers and barriers.
Findings
This research indicates that in the 2007 Melbourne market the drivers were social rather than economic. The data reveal that social reasons are considered more than economic arguments for incorporating sustainability into developments. The business case, or the economic drivers for sustainability alone do not convince developers.
Research limitations/implications
The questionnaire survey informed us about developers' views but not why they have these views. The sample was limited to Melbourne.
Practical implications
More developments are required for developers to become convinced of the benefits. The relatively low price of energy undermines the business case for sustainability in property here and needs to be fully costed.
Originality/value
This paper illustrates that whilst the theoretical framework cites three key areas for sustainability, the reality is that developers are currently driven by social and environmental factors primarily and the business case is not accepted by the majority of developers.

Abstract
Purpose
This paper aims to present a broad review of near-a titanium alloys for high-temperature applications.
Design/methodology/approach
Following a brief introduction of titanium (Ti) alloys, this paper considers the near-α group of Ti alloys, which are the most popular high-temperature Ti alloys developed for a high-temperature application, particularly in compressor disc and blades in aero-engines. The paper is relied on literature within the past decade to discuss phase stability and microstructural effect of alloying elements, plastic deformation and reinforcements used in the development of these alloys.
Findings
The near-a Ti alloys show high potential for high-temperature applications, and many researchers have explored the incorporation of TiC, TiB SiC, Y2O3, La2O3 and Al2O3 reinforcements for improved mechanical properties. Rolling, extrusion, forging and some severe plastic deformation (SPD) techniques, as well as heat treatment methods, have also been explored extensively. There is, however, a paucity of information on SiC, Y2O3 and carbon nanotube reinforcements and their combinations for improved mechanical properties. Information on some SPD techniques such as cyclic extrusion compression, multiaxial compression/forging and repeated corrugation and straightening for this class of alloys is also limited.
Originality/value
This paper provides a topical, technical insight into developments in near-a Ti alloys using literature from within the past decade. It also outlines the future developments of this class of Ti alloys.

Abstract
This study provides a framework for comparing construction management contracts in the UK and the US construction practices. It starts by reviewing previous studies on UK and US contracting practices and explores the main delivery methods, inform of comparison with construction management contracting systems. It examines construction management contracting types, processes and procedures and interaction between the construction manager and other stakeholders. This study was based on a literature review and the result shows the similarities and differences between the American and British CM systems within each practice and between both practices; the distribution of responsibilities and risks both in pre‐construction and during the construction stages; and allocation of responsibility in both practices.

Abstract
Describes a probabilistic methodology for fracture assessments of flawed structures constructed of ferritic steels using the research code WSTRESS. The probabilistic formulation for cleavage fracture implements a multiaxial form of the weakest link model which couples the macroscopic fracture behavior with a micromechanics model based on the statistics of microcracks. The Weibull stress, σw, emerges as a suitable near‐tip parameter to provide a connection between the microregime of failure and remote loading (J). WSTRESS builds on an iterative procedure to incorporate a 3‐D finite element description of the crack‐tip stress field and measured values of fracture toughness to calibrate the Weibull modulus, m, and the scale parameter, σu. Specific features of the code include statistical inference of Weibull parameters based on uncensored and censored models (with maximum likelihood method), construction of confidence intervals, several definitions for the near‐tip fracture process zone and other general facilities such as spatial integration of the stress field (to incorporate the random orientation of microcracks) and stochastic simulation of fracture data using the Monte Carlo method. The code also includes a convenient free‐form command language and a seamless interface with finite element results files stored in Patran binary or ASCII format.

Abstract
Purpose
Construction tradesmen are exposed to high levels of stress that can worsen mental health, negatively impacting safety compliance and organization productivity. Hence, effectively coping with stress to prevent mental ill-health becomes an essential point of reference. Thus, this study aims to examine the role of factors such as resilience and coping strategies in protecting tradesmen against mental ill-health.
Design/methodology/approach
Using a cross-sectional survey design, 110 tradesmen from 65 construction companies were surveyed using the Patient Health Questionnaire, Generalized Anxiety Disorder, Brief Resilience Scale and Ways of Coping Questionnaire.
Findings
The results were analyzed using descriptive statistics and logistic regression analysis. With a 74.5%, 36.4% and 14.6% prevalence rate of self-reported depression, anxiety and suicide ideation among the tradesmen, only positive reappraisal, accepting responsibility coping behaviors and resilience would mitigate the likelihood of developing mental ill-health symptoms.
Originality/value
This study has extended existing literature by providing information vital to building interventions to deal with stressors effectively. This information would benefit individuals, organizations and the economy and equip policymakers with a deeper knowledge base toward improving mental health.

Abstract
Employee dissatisfaction with merit pay is a long‐standing problem. This study introduces four explanatory constructs, based on decisional and interactional fairness notions, that describe how supervisors implement merit pay and predict merit pay satisfaction. Multigroup confirmatory factor analyses, applied to a sample of American employees (N = 415) and a sample of Venezuelan employees (N = 239), show that the five constructs introduced here are distinct from each other and that their measures generalize across countries (cultures and languages).

Abstract
This editorial brings to an end a branded series of articles on the outputs of research concerned with improving the quality of life of older and disabled people. The growing significance of the subject matter addressed throughout this series is illustrated and discussed. As a consequence of the series, it has been realised that papers on topics that previously would have been considered peripheral to the interests of the readership of JIC are now recognised as significant for good health and well‐being.

Abstract
The aim of this study was to provide a pilot evaluation of novel, brief formulation development workshops with direct care staff supporting people with intellectual disabilities who display significant psychosocial difficulties. A series of workshops were designed and delivered to a staff team supporting an individual who had been referred to specialist intellectual disabilities health services. The workshops used a psychosocial framework to facilitate development with care staff of a case formulation for the individual they were supporting. Following the workshops, there were decreases in problematic behaviours displayed by the individual and in the staff team's perception of the severity of these behaviours. The staff team felt that the workshops had had a beneficial impact on their practice. The pilot indicated that the workshops were feasible, positively received and associated with changes in the psychosocial difficulties displayed by the individuals staff were supporting.

Abstract
Purpose
The dearth of green standards (GS) in sub-Saharan Africa is alarming and the green cost premiums (GCP) in seeking certification in emerging markets are scanty. This paper studied the Building Energy-Efficiency Code of Nigeria (BEEC) and estimated the potential GCPs associated with the various energy-efficiency ratings.
Design/methodology/approach
The study retrofitted 150 conventional residential bungalow and maisonette buildings using BEEC's energy-efficiency interventions and performed analytical estimating of the retrofitted designs. The mean cost premium associated with each energy-efficiency intervention is presented as well as their financial benefits and payback periods. The benefits are achievable financial-savings due to a reduction in energy consumption and savings in electricity payment estimated from the average energy demands of each building. An independent t-test was further conducted to determine the cost differential between energy-efficient design (ED) and conventional design over a five-year period.
Findings
The potential GCPs and their payback periods are actually less than feared. The study showed that less than 5% and 21% extra funding would be required to achieve 1 to 4-Star and 5-Star energy-efficiency ratings involving passive design interventions and photovoltaic systems. Passive and active design interventions produced a financial savings of $8.08/m2 in electricity payment and $2.84/m2 per annum in energy consumption reduction. The financial-savings ($10.92/m2) was objective to pay-off the GCPs in less than four years. The independent t-test analysis showed the cost of ED is more economical after four years into the project lifecycle.
Originality/value
The research provides cost benchmarks for navigating cost planning and budgetary decisions during ED implementation and births a departure point for advancing energy-efficient construction in developing markets from the rational economic decision perspective.
