Social learning and network externalities in decision making
Authors: Huang Dongling , Markovitch Dmitri G. , Ying Yuanping 
Published: January 2017

Purpose
This paper aims to identify the effects of social learning and network externalities by conditioning on product quality and early sales momentum. This approach is demonstrated using film sales data.

Design/methodology/approach
This study used econometric modeling approach.

Findings
It was found that both social learning and network externalities have significant and comparable impacts on film choice. We show that the relative effects of network externalities and social learning in the film market are robust to different momentum and quality definitions and to alternative estimation methods.

Originality/value
Scholars have long argued that social learning plays a key role in new product diffusion. In some product categories, consumer choice may also be influenced by network externalities, meaning that purchasing popular products may provide the consumer utility above and beyond that derived from product usage directly. We propose a novel identification approach to help quantify the relative magnitude of these two effects on new product sales.
Analysis of the key influencing factors of haze information dissemination behavior and motivation in WeChat
Authors: Shan Siqing , Liu Mengni , Xu Xiaobo 
Published: January 2017

Purpose
With the development of mobile internet, instant messaging (IM) applications have gradually changed the way to receive information and communicate with friends. Considered as one of the important social media platforms, WeChat is the most popular IM application in China. This paper aims to examine the influence factors of haze information’s dissemination in WeChat.

Design/methodology/approach
Based on the theory of information dissemination and the theory of motivation, three information dissemination elements including information source, information and information receiver were proposed in the structural equation model. The model was tested using data collected from both online and offline questionnaire survey results. The data analysis from 170 valid responses confirmed the path effects that emotional motivation, social motivation of information receiver and the credibility of information source positively influenced WeChat users’ re-transmission intention and information emotional tendency negatively influenced their re-transmission intention.

Findings
The research model revealed these key factors that affected dissemination of haze information in WeChat. More importantly, it provided a decision-making framework to release the public emergency information in WeChat. Hence, the paper made an important contribution to practical guidance to relevant decision makers.

Originality/value
This study contributes to the literature on examining factors affecting the haze information transmission in WeChat. A framework was proposed to describe the information dissemination process which comprises information source, information and information receiver.
Impact of social network heterogeneity and knowledge heterogeneity on the innovation performance of new ventures
Authors: Yang Junping , Wang Feng-Kwei 
Published: January 2017

Purpose
Few studies investigated the influence of heterogeneous knowledge and social networks on the innovation performance of new ventures in emerging economics. Particularly, as the focus of global economic development is paying more attention to emerging economics such as China, Indonesia and India, innovation research in these countries becomes more and more important. As such, this paper aims to propose a theoretical model and designed a survey based on the Theory of Inventive Problem Solving (TRIZ).

Design/methodology/approach
To investigate the influence of network heterogeneity and knowledge heterogeneity on the innovation performance of new ventures, the authors designed a structured questionnaire based on the TRIZ methodology for innovative problem solving to collect data from new ventures established in the past eight years in eastern China.

Findings
The empirical results verify the assumptions of our theoretical model: network heterogeneity has a positive impact on the innovation performance of new ventures; knowledge heterogeneity has a positive impact on the innovation performance of new ventures; network heterogeneity has a positive impact on knowledge heterogeneity.

Originality/value
The main contribution of this paper is that the proposed theoretical model determining the relationship of network heterogeneity and knowledge heterogeneity with the innovation performance of new ventures was empirically tested and verified. This study also empirically verified what types and what sources of social network and knowledge are critically linked to new venture innovation.
Public attitudes towards the employment of ex-offenders with a disability
Authors: Darakai Adrian , Day Andrew , Graffam Joe 
Published: January 2017

Purpose
Ex-prisoners often face significant challenges in their efforts to find meaningful and stable work, undermining their chances of successful reintegration back into the community. These problems are likely to be compounded for those who have an intellectual disability (ID), given evidence that the disabled generally experience high levels of discrimination when applying for and maintaining jobs. The purpose of this paper is to determine whether members of the public hold different attitudes and expectations towards the employment of ex-offenders who have an ID and a history of criminal offending.

Design/methodology/approach
Samples of 642 participants, recruited via social media, were presented with vignettes, and then completed a short survey designed to measure their attitudes and expectations towards the employment of ex-offenders.

Findings
Whilst the presence of a mild ID did not significantly affect community attitudes towards ex-offender employment, it did change expectations about employment outcomes.

Research limitations/implications
It appears that ex-offenders are perceived as a homogenous group of people, despite actual and substantial differences existing within this population.

Practical implications
There is a need to actively educate the community about differences between subgroups of ex-offenders in relation to the employment needs of those with an ID.

Social implications
The social inclusion of ex-offenders with an ID lies at the heart of any effective and progressive criminal justice policy.

Originality/value
This is one of the only studies that has examined public attitudes towards this group.
Successful management of diverse corporate innovation communities
Authors: Roth Angela , Dumbach Martin , Schliffka Barbara , Möslein Kathrin M. 
Published: January 2017

PurposeIncreasing demographic diversity within societies and workforces causes challenges with regard to the innovation performance of companies. By definition, innovation communities nowadays are composed of members with diverse function background and age diversity. The challenging question is how to manage diverse corporate innovation communities. The purpose of this paper is to find out which factors determine the success of corporate innovation communities in times of demographic shifts.Design/methodology/approachThe empirical field to answer the research question are three corporate innovation communities in companies of different industries and size. Multiple case study methodology is applied to gather and analyse the data.FindingsThe study presents an empirically derived framework to structure success factors of diverse corporate innovation communities chronologically in the three phases of preparation, execution and finalization of a community work process. The success factors are described in detail and finally a time sequential guideline for those who are responsible for community management in demographic change is provided.Research limitations/implicationsIt is contributed to the literature on innovation communities and it is shown that innovation communities are not only an instrument to solve innovation tasks but are also a promising means to tackle other challenges of recent demographic changes. As limitation must be considered, that the analysed innovation communities only received corporate support for a short period of time and the supporting organizations operate in manufacturing industries in Germany only.Practical implicationsThe paper highlights that managers need to be aware that diversity in corporate innovation communitiesper sedoes not lead to success. Furthermore, a guideline of success factors for managers of diverse corporate innovation communities is presented which highlights important aspects that managers need to consider during the community work process.Social implicationsDue to demographic shifts in Germany and other European countries, societies in general and workforces in particular have modified. Most pervasive shifts take place with regard to age structures and diversity. Implications how manager could handle diversity successfully are therefore of high relevance for societies.Originality/valueThis study provides a theoretical understanding of the implications of organizational and age diversity on corporate innovation community management. Extant authors have already focussed on success factors in innovation communities and diverse settings isolated, but have not merged these issues.
Ethnic minority membership and depression in the UK and America
Authors: Holttum Sue 
Published: January 2017

Purpose
The purpose of this paper is to discuss two recent studies on depression in members of ethnic minorities, one based in the UK with older people, and one in the USA. The aim was to examine what might lead to depression in these groups, and what might protect people from it.

Design/methodology/approach
The UK-based study examined depression and physical health in older members of the two largest ethnic minority groups in the UK: African Caribbean and South Asian. The US-based study examined whether a sense of belonging to the population group African Americans protected people from depression, as one social theory might predict, or whether racism prevented this protection, as predicted by another theory.

Findings
In London-based older South Asians, depression was explained by their poorer physical health compared to white Europeans. In older people of black Caribbean origin, depression was linked to their social disadvantage. The researchers did not measure people’s experience of discrimination, and other research suggests this can explain both physical illness and depression. The US-based study reported better well-being for people who identified with other African Americans, but not if they also felt negative about African Americans. However, these were weak links, so other things may affect well-being more, such as day-to-day relationships and a range of group memberships.

Originality/value
The London-based study was new in studying depression in older people belonging to the two largest ethnic minority groups in the UK and in white Europeans. The US study tested two competing social theories with different predictions about depression in relation to belonging to an ethnic minority. Both studies highlight the need for more research on discrimination and how to reduce it and its negative effects on both mental and physical health.
A gap in management accounting education: fact or fiction
Authors: Botes Vida Lucia , Sharma Umesh 
Published: January 2017

Purpose
The aim of this paper is to gain insights into the gap that persists between management accounting education (MAE) and practice.

Design/methodology/approach
MAE is examined from four perspectives of the balanced scorecard (BSC), in terms of what is being taught at tertiary level: customer satisfaction, learning and growth, internal business and financial. A survey questionnaire was sent to management accountants selected randomly from a list of practicing management accountants identified by the Chartered Institute of Management Accountants in South Africa.

Findings
The study finds support for allegations that a gap exists between MAE and practice and indicates that to address this gap, a holistic focus using the four perspectives of the BSC would be useful to investigate the gap.

Research limitations/implications
Previous studies in relation to the gap in management education have focused on the lack of skills provided by tertiary education. As one of the few studies to focus on the overall performance of MAE, this study identifies that the gap is not limited to the provision of adequate skills. The findings show that the gap is significant in terms of customer perspective but is not significant in relation to the internal business, learning and growth and financial perspectives of the BSC. The study provides deeper insights into the gap and will help tertiary education providers to improve their performance.

Practical implications
As one of the few studies on gaps between MAE and practice, the study provides insights to the potential gaps. The findings serve as a basis for further empirical and theoretical enquiries.

Originality/value
The study contributes to the management accounting literature by focusing on the gap in MAE using a BSC approach. Rather than single out the lack of skills provided by MAE as a reason for the gap, this paper provides information on the four areas of the BSC as ways to identify the gap.
The market for sustainability assurance services
Authors: Farooq Muhammad Bilal , de Villiers Charl 
Published: January 2017

Purpose
This paper focuses on the market for sustainability assurance (SA) services. The aims of this paper are to review academic efforts in the field, highlighting ground covered, provide a comprehensive understanding of the market for this new form of assurance and identify potential avenues for future research.

Design/methodology/approach
These objectives were met through a review of 50 academic journal articles identified as relevant to the SA field.

Findings
SA is a voluntary exercise in most jurisdictions, and engagements are structured to meet the needs (demands) of the market and the capabilities (supply) of assurance providers. This has given rise to a diverse landscape with engagements of differing scopes and objectives. From a demand side, the literature reveals a number of drivers (both at the macro and micro levels) and inhibitors for SA services. From a supply side, the literature sheds light on the assurance providers operating in the market and the standards they use when undertaking SA services. These practitioners include accountants (the big four) who use ISAE3000 and non-accountants who prefer AA1000AS. The review reveals five broad areas which have been the focus of existing studies. Finally, the study identifies seven avenues for future research in the SA field.

Originality/value
The findings of this paper will prove valuable to practitioners as it will assist them in understanding this new form of assurance. Researchers will benefit from an understanding on ground covered and future avenues for research.
Asia Pacific productivity development determinants
Authors: Ahmed Elsadig Musa , Kialashki Rahim 
Published: January 2017

Purpose
The purpose of this paper is to measure the factors determining the productivity development in the Asia Pacific countries such as Malaysia, Indonesia, Singapore, Philippines, Thailand, China, Japan, Korea, India, Australia and New Zealand.

Design/methodology/approach
The extensive growth theory that is expressed as the decomposition of the contribution of changes in employment, physical capital, foreign direct investment (FDI), human capital (HC), telecommunications investment and total factor productivity (TFP) growth on the selected Asia-Pacific countries’ output growth is used in this study. In this respect, an annual time series data over the period 1970-2012 for the aforementioned variables are employed.

Findings
The study found that the FDI spillover effects through the TFP are considered as productivity-driven economic growth in which the FDI spillover effects have significant effect on the productivity growth of the majority of these countries. It should be noted that most of these countries showed technological progress through the FDI spillover effects that is translated into a form of technology transfer and HC skills development.

Originality/value
This study empirically compared the FDI spillover effects on sustainable productivity growth of the most growing countries in the Asia Pacific region by using modified extensive growth theory that closed the gaps in the past studies and addressed the issues of technology transfer, HC development and sustainable productivity growth brought by the technical progress in these countries through the FDI spillover effects on productivity growth.
Knowledge and entrepreneurship creation: what is the connection?
Authors: Fernandes Cristina , Ferreira João , Raposo Mário , Hernández Ricardo , Diaz-Casero Juan Carlos 
Published: January 2017

PurposeWith this work, the authors seek to advance knowledge in this field mentioned above. The purpose of this paper is to stress the role of two groups of components related to individuals’ knowledge: the intrinsic base of existing knowledge and exposure to external knowledge.Design/methodology/approachThe present study examined the impact of knowledge in the business creation process. Data came from aggregated panel data at the country level taken from the Global Entrepreneurship Monitor over a five-year period (2009-2013).FindingsResults show that knowledge affects the business creation process. The research identifies the following factors as influential: detection of capabilities, entrepreneurial experience, and experience investing in other firms.Research limitations/implicationsThe limitations of the research relate to the data aggregation at the country level. Future research should examine disaggregated GEM data for the three economic stages at the classification level.Practical implicationsThe perception of self-efficacy appears to be critical in understanding the planning of intentional behavior because of its influence on the formation of intentions through situational perceptions of viability.Originality/valueGenerally, the literature that emphasizes the role of knowledge and entrepreneurship in small firms is theoretically limited and focuses solely on the role of knowledge in the decision to start a business.
Accuracy Rates of Ancestry Estimation by Forensic Anthropologists Using Identified Forensic Cases
Authors: Thomas Richard M. , Parks Connie L. , Richard Adam H. 
Published: January 2017

AbstractA common task in forensic anthropology involves the estimation of the ancestry of a decedent by comparing their skeletal morphology and measurements to skeletons of individuals from known geographic groups. However, the accuracy rates of ancestry estimation methods in actual forensic casework have rarely been studied. This article uses 99 forensic cases with identified skeletal remains to develop accuracy rates for ancestry estimations conducted by forensic anthropologists. The overall rate of correct ancestry estimation from these cases is 90.9%, which is comparable to most research‐derived rates and those reported by individual practitioners. Statistical tests showed no significant difference in accuracy rates depending on examiner education level or on the estimated or identified ancestry. More recent cases showed a significantly higher accuracy rate. The incorporation of metric analyses into the ancestry estimate in these cases led to a higher accuracy rate.

Published: January 2017

AbstractPurple sweet potato (PSP) is widely grown in Asia and considered as a healthy vegetable. The objective of the current study was to determine the anti‐obesity effect of the PSP on high fat diet induced obese C57BL/6J mice. The mice were administrated with high fat diet supplemented with the sweet potato (SP) or PSP at the concentration of 15% and 30% for 12 wk, respectively. The results showed that the supplementation of SP or PSP at 30% significantly ameliorated high fat diet induced obesity and its associated risk factors, including reduction of body weight and fat accumulation, improvement of lipid profile and modulation of energy expenditure. Moreover, PSP also posed beneficial effect on the liver and kidney functions. These results indicate that PSP and SP have anti‐obesity effect and are effective to reduce the metabolic risk.
The Potential Source of B. licheniformis Contamination During Whey Protein Concentrate 80 Manufacture
Authors: Md Zain Siti Norbaizura , Bennett Rod , Flint Steve 
Published: January 2017

AbstractThe objective of this study was to determine the possible source of predominant Bacillus licheniformis contamination in a whey protein concentrate (WPC) 80 manufacturing plant. Traditionally, microbial contaminants of WPC were believed to grow on the membrane surfaces of the ultrafiltration plant as this represents the largest surface area in the plant. Changes from hot to cold ultrafiltration have reduced the growth potential for bacteria on the membrane surfaces. Our recent studies of WPCs have shown the predominant microflora B. licheniformis would not grow in the membrane plant because of the low temperature (10 °C) and must be growing elsewhere. Contamination of dairy products is mostly due to bacteria being released from biofilm in the processing plant rather from the farm itself. Three different reconstituted WPC media at 1%, 5%, and 20% were used for biofilm growth and our results showed that B. licheniformis formed the best biofilm at 1% (low solids). Further investigations were done using 3 different media; tryptic soy broth, 1% reconstituted WPC80, and 1% reconstituted WPC80 enriched with lactose and minerals to examine biofilm growth of B. licheniformis on stainless steel. Thirty‐three B. licheniformis isolates varied in their ability to form biofilm on stainless steel with stronger biofilm in the presence of minerals. The source of biofilms of thermo‐resistant bacteria such as B. licheniformis is believed to be before the ultrafiltration zone represented by the 1% WPC with lactose and minerals where the whey protein concentration is about 0.6%.
Effects of Impervious Area and BMP Implementation and Design on Storm Runoff and Water Quality in Eight Small Watersheds
Authors: Aulenbach Brent T. , Landers Mark N. , Musser Jonathan W. , Painter Jaime A. 
Published: January 2017

AbstractThe effects of increases in effective impervious area (EIA) and the implementation of water quality protection designed detention pond best management practices (BMPs) on storm runoff and stormwater quality were assessed in Gwinnett County, Georgia, for the period 2001‐2008. Trends among eight small watersheds were compared, using a time trend study design. Significant trends were detected in three storm hydrologic metrics and in five water quality constituents that were adjusted for variability in storm characteristics and climate. Trends in EIA ranged from 0.10 to 1.35, and changes in EIA treated by BMPs ranged from 0.19 to 1.32; both expressed in units of percentage of drainage area per year. Trend relations indicated that for every 1% increase in watershed EIA, about 2.6, 1.1, and 1.5% increases in EIA treated by BMPs would be required to counteract the effects of EIA added to the watersheds on peak streamflow, stormwater yield, and storm streamflow runoff, respectively. Relations between trends in EIA, BMP implementation, and water quality were counterintuitive. This may be the result of (1) changes in constituent inputs in the watersheds, especially downstream of areas treated by BMPs; (2) BMPs may have increased the duration of stormflow that results in downstream channel erosion; and/or (3) spurious relationships between increases in EIA, BMP implementation, and constituent inputs with development rates.
