Cyber-physical systems integration of building information models and the physical construction
Authors: Akanmu Abiola , Anumba Chimay J. 
Published: September 2015

Purpose
– In spite of the benefits of virtual models in the building and construction industry, the full potential of these models, especially in the construction and operation phases, remains largely unrealized. With the increasing developments in information and communication technology, a number of attempts have been made to extend the use of these models, through the development of integration approaches and technologies. However, the issue of integrating the virtual model and the physical construction such as to enable bi-directional coordination, has not been adequately addressed. Thus, the purpose of this paper is to investigate the application of a cyber-physical systems (CPS) approach in enhancing bi-directional coordination between virtual models and the physical construction.

Design/methodology/approach
– This research employs scenario development rapid prototyping to illustrate CPS integration in the construction industry, with a particular focus on facilitating bi-directional coordination. The proof-of-concept prototype systems developed were validated using a focus group consisting of industry practitioners.

Findings
– Bi-directional coordination between virtual models and the physical construction has the potential to improve real-time progress monitoring and control of the construction process, tracking of changes and model updates, information exchange between the design office and the job site, real-time documentation of the as-built status of high-value components and improved sustainability practices.

Originality/value
– This paper adds value to the construction industry by demonstrating the application of the CPS approach in enhancing bi-directional coordination between virtual models and the physical construction through the development of system architectures, scenarios and prototype systems.
Community health worker model: its implementation and importance in reaching refugee populations in the U.S.
Authors: Nunnery Danielle , Dharod Jigna 
Published: September 2015

Purpose
– The community health workers (CHWs) model, which refers to individuals from the same community, sharing the same culture and origin, was used to conduct lifestyle, food and health assessments in the refugee and immigrant communities in the study area. In order to understand the process and effectiveness of CHW model, the purpose of this paper is to identify key characteristics of CHWs; and, describe the major roles CHWs play in reaching and carrying out health-based research among under-served refugee populations.

Design/methodology/approach
– The results of this paper reflect a grounded theory approach that specifically analyzed core categories or themes of the CHW model that were observed and recorded from the process of a larger study examining health and diet habits of refugees. In this study, women from the study community were recruited to be trained as CHWs. Recruitment criteria for potential CHWs included women from the same origin of the study community, live in the study area for several years and have familiarity with the community, and possess basic English reading and writing skills.

Findings
– The results showed that CHWs were most effective when they possessed specific key characteristics. These characteristics included being invested in the community and research project, being objective and non-judgmental and able to understand guidelines of research ethics. The CHW helped to carry out the study by acting as a gatekeeper by building trust among community members and, by acting as a cultural broker by explaining the study questions using culturally appropriate probes.

Research limitations/implications
– The CHWs described in this study represent the key characteristics of effectiveness they possess in reaching refugee and immigrant groups in the USA. The limitation reflects the need for further examination of the characteristics that make for effective CHWs in a US-based refugee resettlement context concerning health-based research and outreach reaching a general low-income, racial/ethnic minority groups in the USA.

Practical implications
– The CHW model is key in conducting culturally appropriate research with an under-served and difficult to reach population.

Originality/value
– There is limited published research on the use of the CHW in health-based research in the USA resettlement context and this research study is one step toward closing the gap in our examination of the CHW model.
A comparative study of Turkish-speaking migrants and natives living in Vienna/Austria concerning their life satisfaction – with a particular focus on satisfaction regarding their health
Authors: Özlü-Erkilic Zeliha , Winkler Dietmar , Popow Christian , Zesch Heidi Elisabeth , AKKAYA-KALAYCI Türkan 
Published: September 2015

Purpose– The migration background can influence the life satisfaction of migrants. The purpose of this paper is to examine the life satisfaction of migrants and particularly the satisfaction regarding their health in comparison to natives.Design/methodology/approach– The life satisfaction of 50 Turkish-speaking migrants living in Vienna was compared with the life satisfaction of 50 native Austrians by the questionnaire of life satisfaction by Fahrenberget al.(2000).Findings– Turkish-speaking migrants had lower values than natives in all scales of the questionnaire concerning life satisfaction. Turkish-speaking women reported the lowest satisfaction regarding their health state. In the migrant group the satisfaction regarding health decreased with increasing age.Research limitations/implications– The Turkish version of the questionnaire was translated into Turkish by authors but not formally validated. Furthermore acculturation strategies as well as the mental and physical health state of the participant, which can crucially influence the life satisfaction of migrants, were not surveyed.Practical implications– Migrants have lower life satisfaction possibly because of their physical and mental health problems. Therefore in countries with a high proportion of migrants the health-care system should be adapted for the needs of migrants, especially for the needs of women and older migrants in order to increase the utilization of the health-care services, primarily the use of the preventive health-care services.Social implications– The results of the present study can be helpful to develop strategies for improving the life satisfaction of migrants, especially the satisfaction regarding their health.Originality/value– To the authors’ knowledge, the present study is the first research project in Vienna conducted to estimate the impact of migration background on life satisfaction.
Digital commerce in emerging economies
Authors: Akhlaq Ather , Ahmed Ejaz 
Published: September 2015

Purpose
– More research is needed to understand the online shopping behaviors and intentions of consumers in emerging economies. The purpose of this paper is to examine the extent to which key variables from the Technology Acceptance Model (perceived usefulness (PU) and ease of use (PEOU)), and others theoretically associated with digital engagement (distrust, perceived risk (PR), perceived enjoyment (PE) and legal framework (LF)), accounted for variation in online shopping intentions in Pakistan, focussing on affiliates of a large metropolitan university.

Design/methodology/approach
– Online survey using a convenience sample of university staff, students and alumni recruited through the university’s online network. A questionnaire capturing the above constructs was tested for content validity and reliability prior to dissemination. The survey results were factor analyzed to determine the degree to which the constructs were independent, and regression was used to examine their ability to predict online purchasing intentions. User characteristics were analyzed descriptively.

Findings
– All six independent factors, PU, PEOU, PR, PE, distrust and LF, in the model were independently predictive of intention to shop online and supported the theoretical model by demonstrating the predicted direction of the relationship.

Research limitations/implications
– There are limitations in the generalizability of the findings. Most of the data being collected were only from Karachi, the biggest metropolitan city and the business hub of Pakistan.

Practical implications
– This research may help retailers in becoming e-tailers. The model would also help existing e-tailers to streamline their business according to the research findings. In addition, government may work on policies to provide a better online business environment to the people of Pakistan.

Originality/value
– A new online shopping model has been discovered for an emerging market, Pakistan. Developing countries could take advantage of this model to get real insights of their e-tailing industry.
Purchasing power parity as a long-term memory process
Authors: Triki Mohamed Bilel , Maktouf Samir 
Published: September 2015

Purpose– The purpose of this paper is to focus on whether the deviations from the cointegrating relationship possess long memory and the fractional cointegration analyses may capture a wider range of mean-reversion behaviour than standard cointegration analyses.Design/methodology/approach– This paper uses a fractional cointegration technique to test the purchasing power parity (PPP).Findings– The authors found that PPP held, but very weakly, in the long run between the Argentine, Brazil, Chile, Colombia, Indonesia, Korea, Mexico, Thailand and Venezuela and US exchange rate during our floating exchange rate period but that the deviations from it did not follow a stationary process. Nevertheless, it is also found that the deviations from PPP exists and can be characterized by a fractionally integrated process in nine out of 13 countries studied.Originality/value– The findings are consistent with the consensus of the empirical literature, reviewed earlier in this paper, on PPP between Argentine, Brazil, Chile, Colombia, Indonesia, Korea, Mexico, Thailand and Venezuela and the USA.
Testing three materialism life-course theories in South Africa
Authors: Duh Helen 
Published: September 2015

Purpose
– About 80 per cent of consumers in the world reside in emerging consumer markets (ECM). Thus, consumer behaviour theories and models should be tested for validation in ECM such as South Africa (socio-economically and culturally diverse). The purpose of this paper is to test three (human capital, stress and socialization) life-course theoretical perspectives on materialism among South African young adults. Employing the three life-course theoretical perspectives, it was posited that disruptive family events experienced during adolescence will affect materialism at young adulthood directly and indirectly through family resources received, perceived stress from family disruptions and peer communication about consumption.

Design/methodology/approach
– In total, 300 South African young adults were surveyed. Structural equation modelling was used to test eight hypotheses developed from the three life-course theoretical perspectives on materialism. Independent-samples t-test was first conducted to assess whether the respondents were materialistic.

Findings
– The South African young adults were found to be materialistic and this was explained by peer communication about consumption during adolescence (socialization life-course theoretical perspective). Disruptive family events experienced during adolescence significantly affected family resources negatively, and perceived stress positively, but these outcomes had no impact on materialism at young adulthood as the human capital and stress life-course theoretical perspectives suggest.

Originality/value
– The results reinforce the need to test the validity of western theories in an African context. The test can improve theories and can help advance knowledge about consumer diversity across cultures.
A performance evaluation of Chinese mutual funds
Authors: Kiymaz Halil 
Published: September 2015

Purpose
– The purpose of this paper is to examine the performance of Chinese mutual funds during the period of January 2000 to July 2013. Emerging market funds provide investors with alternative risk exposure for their portfolios. The Chinese market has developed rapidly and differs from developed markets regarding wide range of market and economic characteristics, including size, liquidity, and regulation. The performance of these funds is investigated by using various risk adjusted measures. The study also compares performances of mutual fund subgroups and explains the factors influencing their performances.

Design/methodology/approach
– This is an empirical paper using various risk performance measures. These measures include the Sharpe ratio, Information ratio, Treynor ratio, M-squared and Jensen’s α. The data comprises 1,037 funds. These funds are further divided into ten subgroup of funds based on their classification: equity (484); aggressive allocation (95 funds); conservative allocation (18 funds); moderate allocation (85 funds); aggressive bond (92 funds); normal bond (52 funds); guaranteed (29 funds); money market (53 funds); and QDII funds (119 funds). A cross-sectional analysis of fund performance is performed using Sharpe and Jensen’s measures as dependent variables and fund-specific variables (Age, Turnover, Tenure, Frontload, Redemption fees, and Management fees), market-specific variables (P/E ratio, P/B ratio, Market capitalization), and fund types as independent variables.

Findings
– The findings show that Chinese funds generate positive αs for their investors. The highest return is provided with aggressive allocation funds followed by moderately aggressive allocation funds. The average Jensen’s α is the highest in aggressive allocation funds. QDII funds do not provide significant positive αs; in several instances αs are negative. Further analysis of sub-periods show that Chinese funds do not consistently provide excess returns and show great variations. The study also finds that older funds, funds with higher fees, high price to book ratio, and smaller funds continue to perform better than other funds.

Originality/value
– This study adds value by focussing on Chinese funds and risk/return characteristics of these funds. The research will further explore factors explaining these returns.
An empirical analysis of funds’ alternative measures in the mean absolute deviation (MAD) framework
Authors: Tavakoli Baghdadabad Mohammad Reza 
Published: September 2015

Purpose
– The purpose of this paper is to provide an attempt to evaluate the risk-adjusted performance of international mutual funds using the risk statistic generated by the mean absolute deviation (MAD) and promote the ability of portfolio managers and investors to make the logical decisions for selecting different funds using the new optimized measures.

Design/methodology/approach
– This study evaluates the performance of 50 international mutual funds using optimized risk-adjusted measures by the MAD over the monthly period 2001-2010. Using 50 linear programming models, the MAD is first computed by the linear programming models, and then seven performance measures of Treynor, Sharpe, Jensen’s α, M2, information ratio (IR), MSR, and FPI are optimized and proposed by the MAD to evaluate the mutual funds.

Findings
– The empirical evidence detects that the MAD is an important determinant to evaluate the funds’ performance. Using the MAD statistic, this paper shows that new optimized measures are mostly over-performed by the benchmark index; in addition, these optimized measures have close correlation with each other. The results, therefore, detect the importance of using new optimized measures in evaluating the mutual funds’ performance.

Practical implications
– The result of this study can be directly used as an initial data for decision of investors and portfolio managers who are seeking the possibility of participating in the global stock market by the international mutual funds.

Originality/value
– This paper is the first study which optimizes the variance of returns in the MAD framework for each fund to propose new seven optimized measures of Treynor, Sharpe, Jensen’s α, M2, IR, MSR, and FPI.
Drug term trends in American hip-hop lyrics
Authors: Inkster Becky , Sule Akeem 
Published: September 2015

Purpose– Many young people around the world embrace hip-hop music and culture. Since the genre’s conception in the 1970s, hip-hop music and lyrics have made regular references to drugs. Understanding the relevance of these documented trends is important, especially as adolescence is a period of high risk for substance misuse. The purpose of this paper is to explore how and possibly why different lyrical trends in hip-hop music have emerged, risen and fallen out of popularity by examining word usage frequency of drug terminology in hip-hop lyrics spanning several decades of this genre.Design/methodology/approach– Electronic searches were completed using an open source database known as Rap Genius Rap Stats, which contains verified annotations and text. Word frequency was plotted against time using data available from 1988 to 2015. Word frequency was defined as a percentage of the number of hip-hop songs containing a specific drug-term (per year) based on the number of hip-hop songs recorded/produced (that year). Standardized “medical/pharmaceutical” terminologies and common “street” terminologies were plotted independently for time series visualization. Drug terms were represented using the highest frequency search term. Generic “street” terms with multiple meanings were excluded.Findings– As might be predicted, the usage of “street” terms in hip-hop lyrics was more frequently observed than the usage of “medical/pharmaceutical” terms. An exception was the term “crack”, which was included in both plots as this word could be referenced as a “street” term and as a “medical/pharmaceutical” term. The authors observed larger fluctuations in “street” term usage across time relative to only slight fluctuations of “medical/pharmaceutical” term usage across time.Originality/value– In this study, the authors illustrate several drug terminology trends in hip-hop lyrics. The authors discuss some of the socio-political, socio-demographic and geographical implications that may have influenced these trends, such as the rise of the “street” term molly that emerged when references to molly made by hip-hop artists became increasingly popular and a more suburban demographic transpired. This preliminary work may help to enhance two-way youth-oriented communication between health care professionals and service users, possibly improving the translation of drug-related medical messages. The preliminary work may also inform future research to consider whether such lyrical trends precede or follow changes in population substance use.
Exploring the components and impact of social prescribing
Authors: Kilgarriff-Foster Alexis , O'Cathain Alicia 
Published: September 2015

Purpose
– Social prescribing are short-term intermediary services that facilitate patients with psychosocial needs to engage in non-clinical support. However, little is known about the components and potential impact of social prescribing. The paper aims to discuss this issue.

Design/methodology/approach
– A review was conducted to explore the evidence based on social prescribing including mapping its key components and potential impact. Database, internet and hand searching was utilised to identify relevant studies. Data extraction and narrative analysis was undertaken to explore the issues.

Findings
– In total, 24 studies met the inclusion criteria. The studies were diverse in their methodologies and the services evaluated. Stakeholders such as general practitioners and patients perceived that social prescribing increased patients’ mental well-being and decreased health service use. However, the quantitative evidence supporting this was limited. The only randomised-controlled trial showed a decrease in symptoms and increase in functional well-being at four months. The other non-controlled designs had large drop-out rates limiting their value in determining effectiveness.

Research limitations/implications
– Further research is needed on the effectiveness and cost-effectiveness of social prescribing using robust evaluative designs.

Originality/value
– This is the first review of generic social prescribing services focusing on the general evidence base.
Exploring the Facebook Like: a product and service perspective
Authors: Pelletier Mark J. , Blakeney Horky Alisha 
Published: September 2015

Purpose
– The purpose of this exploratory study is to expand the knowledge of the current literature stream and to attempt to more fully understand the simple but singularly unique aspect of social networking communication that is the Facebook “Like”. To this end, motivations behind liking a brand are explored, as well as the interactions that occur between the company and consumer as a result of this Facebook interaction. Next, we look at differing levels of interaction for liked product and service brands on Facebook. Specifically exploring if there are differences with how Facebook users engage with liked product and service brands.

Design/methodology/approach
– The authors first engage in an exploratory, qualitative-based research to look at the motivations and consequences associated with liking product and service brands, using a sample of 160 Facebook users. Next, an ANOVA analysis is performed using an online sample of 264 respondents recruited from Amazon Mechanical Turk.

Findings
– The qualitative analysis reveals differing motivations for liking brands on Facebook and suggests that generating Facebook Likes can indeed have positive, if unacknowledged, outcomes for the firm. Further, while there is no significant difference in perceptions of brand knowledge between product- and service-based brands, there is a significant difference in perceptions of brand connectedness between brand types, with consumers reporting a greater sense of connection to the service brands and higher levels of brand attitude and purchase intention for product-based brands. It is also shown that consumers have a greater intention of reading and liking posts from product-based brands.

Originality/value
– This paper explores and attempts to move toward clarification of the gap that exists between “quality” versus “quantity” valuations of a Facebook Like.
