Understanding mobile augmented reality adoption in a consumer context
Authors: Paulo Maria Madalena , Rita Paulo , Oliveira Tiago , Moro Sérgio 
Published: June 2018

Purpose
The purpose of this paper is to further our knowledge of what influences users to adopt mobile augmented reality in tourism (MART). A conceptual model is proposed, combining the extension of Unified Theory of Acceptance and Usage of Technology (UTAUT2) with task technology fit (TTF), to explain behavioural intention and user behaviour of MART adopters.

Design/methodology/approach
A questionnaire was completed by a sample of 335 respondents in Portugal. Both UTAUT2 and TTF were combined into a new model from which several hypotheses were drawn based upon the literature.

Findings
The results have shown that the model explains 72 per cent of the variance in behaviour intention to use MART and 45 per cent of the variance in user behaviour.

Originality/value
MART is becoming increasingly known to travellers as it provides the user diverse and useful information with a real relationship with the world. By studying behaviour and what influences consumers to use MART, this study aims to advance the research into new technologies in tourism.
Critical success factors of small and medium-sized enterprises in Palestine
Authors: Alfoqahaa Sam 
Published: June 2018

Purpose
The purpose of this paper is to investigate the success of small and medium enterprises (SMEs) in Palestine, and thus to contribute to the existing knowledge on the critical success factors (CSFs) of SMEs in the Palestinian context, especially in the West Bank.

Design/methodology/approach
The study is comprised a survey of a convenience sample of 370 SMEs operating in the West Bank, Palestine. It uses a multiple regression analysis to examine the effect of a set of CSFs, namely, reputation of the brand, excellence of customer services, reliable delivery and product innovation on the success of SMEs.

Findings
The results show that brand reputation, excellence of customer of services and reliable delivery strongly influence SME success, while innovation is weakly associated with SME success. These results imply that success is tied to customers and competition more than to production, structures or finance. That is, reputable brands, excellent customer service and reliable delivery are means to success according to the results of this research.

Practical implications
The study emphasizes the need for Palestinian SMEs to maintain and develop their brand reputation, institutionalize customer service and develop its logistical systems and practices. Generally, the study suggests that there are specific investment areas for SMEs that can contribute to achieving success. Specifically, excellence in customer service was found to be the factor most linked to the success of SMEs, followed by reliable delivery and then by brand reputation and innovation.

Originality/value
While plenty of research has been done on what contributes to the failure or success of SMEs, research on CSFs for SMEs is limited. The study combines four CSFs not previously used in combination to model the successful performance of SMEs in general and in the Palestinian context in particular. Only some specific factors are critical to the success of SMEs and should be the focal point of SMEs’ efforts as long as they are consistent with their nature as small economic entities competing with big companies in small markets. Thus, instead of using general factors of SME success, the study explains how success becomes more possible through specifying areas for decision-making or activities for the entrepreneurs to undertake, keeping in mind that there is a mechanism by which these factors work together toward the success of the SME.

Published: June 2018

Purpose
This study examines the factors that explain Ghanaian business students’ intentions to pursue a Certified Professional Accounting (CPA) qualification.

Design/methodology/approach
The study uses survey method of research and mainly used questionnaires as data collection instrument to elicit information from the respondent group. Using a total of 641 business students from the University of Ghana Business School, a mixture of factor analysis and logistic regression analysis techniques was used in investigating the study objectives.

Findings
Results from the regression analysis demonstrate that students’ preference and beliefs about accounting professional qualification, academic major and grade point average are significantly associated with their intentions to pursue a CPA qualification. Moreover, majority of the sampled respondents (47.9 per cent) with the desire to pursue a CPA qualification prefer to be affiliated with the Association of Chartered Certified Accountants, 27.2 per cent prefer the Institute of Charted Accountant Ghana qualification, while only 7 per cent of the students prefer to be affiliated with the Chartered Institute of Management Accountant.

Research limitations/implications
The findings from this study have important implications for the various professional accountancy bodies, accounting educators and other stakeholders interested in promoting the choice of accounting as a career path among university students.

Practical implications
The results indicate that, as part of the broader strategy to increase the number of professional accountants in Ghana, there is the need to promote the study of accounting at the undergraduate level in the various universities in the country.

Originality/value
This study uniquely uses the behavioral decision theory to explain the dominant factors associated with students’ intentions to pursue a CPA qualification.

Authors: N.S. Shashikumar , B.J. Gireesha , Mahanthesh B. , B.C. Prasannakumara 
Published: June 2018

Purpose
The microfluidics has a wide range of applications, such as micro heat exchanger, micropumps, micromixers, cooling systems for microelectronic devices, fuel cells and microturbines. However, the enhancement of thermal energy is one of the challenges in these applications. Therefore, the purpose of this paper is to enhance heat transfer in a microchannel flow by utilizing carbon nanotubes (CNTs). MHD Brinkman-Forchheimer flow in a planar microchannel with multiple slips is considered. Aspects of viscous and Joule heating are also deployed. The consequences are presented in two different carbon nanofluids.

Design/methodology/approach
The governing equations are modeled with the help of conservation equations of flow and energy under the steady-state situation. The governing equations are non-dimensionalized through dimensionless variables. The dimensionless expressions are treated via Runge-Kutta-Fehlberg-based shooting scheme. Pertinent results of velocity, skin friction coefficient, temperature and Nusselt number for assorted values of physical parameters are comprehensively discussed. Also, a closed-form solution is obtained for momentum equation for a particular case. Numerical results agree perfectly with the analytical results.

Findings
It is established that multiple slip effect is favorable for velocity and temperature fields. The velocity field of multi-walled carbon nanotubes (MWCNTs) nanofluid is lower than single-walled carbon nanotubes (SWCNTs)-nanofluid, while thermal field, Nusselt number and drag force are higher in the case of MWCNT-nanofluid than SWCNT-nanofluid. The impact of nanotubes (SWCNTs and MWCNTs) is constructive for thermal boundary layer growth.

Practical implications
This study may provide useful information to improve the thermal management of microelectromechanical systems.

Originality/value
The effects of CNTs in microchannel flow by utilizing viscous dissipation and Joule heating are first time investigated. The results for SWCNTs and MWCNTs have been compared.

Published: June 2018

PurposeThe purpose of this paper is to examine industry herding among the institutional investors and to find whether their herding behaviour is intentional or unintentional.Design/methodology/approachThe study uses Lakonishok et al. (1992) model to examine the presence of industry herding behaviour among institutional investors. To determine whether the herding observed is intentional or unintentional, herding measure is regressed with volatility, volume, beta and return. The period of the study is from 1 April 2005-31 March 2015.FindingsThe findings of the study showed that though institutional investors have herding tendency towards most of the industries, in the overall period industry herding was not significant. The herding found in some industrial sectors was linked to economic performance of those sectors in India during the period of study and hence the herding was unintentional in nature.Research limitations/implicationsThis is the first attempt to study industry herding among institutional investors and their intent in Indian market ever since the country opened its market to foreign investors in a big way. Present study is limited to the use of only bulk/block data instead of the entire trading data for the period.Originality/valueThis study is the first attempt to investigate industry herding behaviour of institutional investors in the market using their bulk and block trading data. The herding observed in well performing industries has been shown to be unintentional and hence rational. The results indicate that the entry of big institutional investors, including foreign institutions into the Indian market has not destabilised the market by irrational herding.
Intransitivity increases plant functional diversity by limiting dominance in drylands worldwide

Published: June 2018

Abstract

Biotic interactions are key determinants of plant community structure. Indirect interactions such as intransitivity (i.e., the absence of competitive hierarchies among species) have been hypothesized to benefit diversity within plant communities. However, their effect on functional diversity remains scarcely explored in real communities. Here, we develop a novel approach to infer intransitivity from plant spatial patterns and functional traits (height and specific leaf area) and quantify its effect on different components of plant diversity along environmental gradients in 100 drylands from all continents except Antarctica.

We first calculated the spatial association pattern for all perennials to infer competition between species. Trait values were used as a proxy of competitive hierarchies to infer the direction of these interactions. We used multiple regression models to evaluate how intransitivity responds to environmental variables (mean annual temperature and precipitation, precipitation seasonality, soil pH, sand content and woody cover). We also used confirmatory path analysis to evaluate the effects of intransitivity on species richness and evenness, trait dispersion and functional diversity.

Intransitivity mostly responded to climatic variables and significantly increased with precipitation scarcity and seasonality. We found that intransitivity had significant effects on functional diversity, mostly by promoting plant community evenness. However, the dominance of woody vegetation (steppes versus shrublands) modulated this effect.

Synthesis. Intransitivity increased the functional diversity of drylands, particularly under high rainfall seasonality, by limiting functionally dominant species. Our findings specify how intransitivity structures the functional diversity of dryland vegetation worldwide. Intransitivity may be particularly important in ecosystems where the availability of abiotic resources changes over time, thereby breaking down inherent competitive hierarchies between plant species. Neglecting intransitivity will bias our estimation of the impacts of biotic interactions on plant communities, a fundamental issue to fully understand how plant communities will respond to ongoing environmental changes.
Service delivery and intervention intensity for phonology‐based speech sound disorders
Authors: Sugden Eleanor , Baker Elise , Munro Natalie , Williams A. Lynn , Trivette Carol M. 
Published: June 2018

AbstractBackgroundWhen planning evidence‐based intervention services for children with phonology‐based speech sound disorders (SSD), speech and language therapists (SLTs) need to integrate research evidence regarding service delivery and intervention intensity within their clinical practice. However, relatively little is known about the optimal intensity of phonological interventions and whether SLTs’ services align with the research evidence.AimsThe aims are twofold. First, to review external evidence (i.e., empirical research evidence external to day‐to‐day clinical practice) regarding service delivery and intervention intensity for phonological interventions. Second, to investigate SLTs’ clinical practice with children with phonology‐based SSD in Australia, focusing on service delivery and intensity. By considering these complementary sources of evidence, SLTs and researchers will be better placed to understand the state of the external evidence regarding the delivery of phonological interventions and appreciate the challenges facing SLTs in providing evidence‐based services.Methods & ProceduresTwo studies are presented. The first is a review of phonological intervention research published between 1979 and 2016. Details regarding service delivery and intervention intensity were extracted from the 199 papers that met inclusion criteria identified through a systematic search. The second study was an online survey of 288 SLTs working in Australia, focused on the service delivery and intensity of intervention provided in clinical practice.Main ContributionsThere is a gap between the external evidence regarding service delivery and intervention intensity and the internal evidence from clinical practice. Most published intervention research has reported to provide intervention two to three times per week in individual sessions delivered by an SLT in a university clinic, in sessions lasting 30–60 min comprising 100 production trials. SLTs reported providing services at intensities below that found in the literature. Further, they reported workplace, client and clinician factors that influenced the intensity of intervention they were able to provide to children with phonology‐based SSD.Conclusions & ImplicationsInsufficient detail in the reporting of intervention intensity within published research coupled with service delivery constraints may affect the implementation of empirical evidence into everyday clinical practice. Research investigating innovative solutions to service delivery challenges is needed to provide SLTs with evidence that is relevant and feasible for clinical practice.
Arbuscular mycorrhizal fungi stimulate organic phosphate mobilization associated with changing bacterial community structure under field conditions

Published: June 2018

SummaryThe extraradical hyphae of arbuscular mycorrhizal fungi (AMF) harbour and interact with a microbial community performing multiple functions. However, how the AMF‐microbiome interaction influences the phosphorus (P) acquisition efficiency of the mycorrhizal pathway is unclear. Here we investigated whether AMF and their hyphal microbiome play a role in promoting organic phosphorus (P) mineralizing under field conditions. We developed an AMF hyphae in‐growth core system for the field using PVC tubes sealed with membrane with different size of pores (30 or 0.45 μm) to allow or deny AMF hyphae access to a patch of organic P in root‐free soil. AMF and their hyphae associated microbiome played a role in enhancing soil organic P mineralization in situ in the field, which was shown to be a function of the change in bacteria community on the hyphae surface. The bacterial communities attached to the AMF hyphae surface were significantly different from those in the bulk soil. Importantly, AMF hyphae recruited bacteria that produced alkaline phosphatase and provided a function that was absent from the hyphae. These results demonstrate the importance of understanding trophic interactions to be able to gain insight into the functional controls of nutrient cycles in the rhizosphere.
Casting a Wide Net for Innovation: Mediating Effect of R&D Human and Social Capital to Unlock the Value from Alliance Portfolio Diversity
Authors: Garcia Martinez Marian , Zouaghi Ferdaous , Sanchez Garcia Mercedes 
Published: June 2018

AbstractThis paper examines the performance effects associated with different alliance portfolio configurations in terms of geographical location and partner type. Based on these distinctions, the authors hypothesize that more diverse alliance portfolios enable firms to gain and exploit innovation opportunities. Additionally, the mediating effects of R&D human and social capital on the R&D alliance portfolio diversity–innovation performance relationship are explored. The authors reason that the absorptive capacity of R&D intellectual capital determines a firm's potential gains from highly diverse alliance portfolios. From panel data of manufacturing firms in Spain for the period 2008–2013, the results confirm the inverted U‐shaped relationship between alliance portfolio diversity and firm innovation performance, implying that both insufficient and excessive alliance portfolio diversity may be detrimental to firm innovativeness. Additionally, R&D human and social capital partially mediates the R&D alliance diversity–innovation performance relationship, emphasizing the importance of internal capabilities to leverage the benefits of highly diverse alliance portfolios. These findings add a dynamic dimension to the conceptualization of alliance portfolios and how firms create value by balancing explorative and exploitative alliances.
Smallholder participation in vegetable exports and age‐disaggregated labor allocation in Northern Tanzania
Authors: Benali Marwan , Brümmer Bernhard , Afari‐Sefa Victor 
Published: June 2018

AbstractModern agricultural supply chains have been playing an increasingly important role in developing countries and have had significant effects on rural labor markets. This article analyses the effects of smallholder farmer participation in export vegetable supply chains in Northern Tanzania on both household hired labor demand and off‐farm labor supply, using an age‐disaggregated approach. In our sample, neither separability nor exogeneity of smallholder farmer participation in export supply chains can be rejected. Hence, we apply lognormal double‐hurdle models and find that participation in export supply chains positively affects households’ decision to hire labor from all age groups. We also find that it increases the unconditional overall level of hired labor demand, while the age‐disaggregated analysis shows that these effects mostly benefit rural youth. However, our sample does not allow us to establish statistically significant evidence of an effect on household off‐farm labor supply although the point estimates point to nonnegligible positive effect sizes.
Are maize marketers averse to quality loss in supplies? A case study from Ghana
Authors: Bassey Nkoyo Etim , Kuhn Arnim , Storm Hugo 
Published: June 2018

AbstractTo ensure sustainable post‐harvest loss reduction, markets that are averse to quality loss and provide incentives for farmers to supply high quality produce are crucial. Such markets will be averse to quality loss, offering distinct prices and substantial rewards to farmers for the supply of quality produce. Farmers in sub‐Saharan Africa (SSA), where informal markets exist, have often assessed the rewards for the supply of quality produce as inadequate. Hence, this study investigates if intermediary buyers are actually indifferent to quality loss in supplies based on two scenarios—the informal market scenario and a hypothesized grade scenario. The analysis builds on survey data from marketers in two informal maize markets in Ghana. For the hypothesized grade scenario, random effect regression was used to examine the influence of marketer‐specific characteristics on premiums offered to farmers over different quality levels. The findings suggest that although informal markets seem not to adequately value loss reduction, investing in institutional infrastructures, such as grades and standards can change this. Furthermore, interaction among marketers and association participation positively influences the value marketers place on quality loss reduction. The result highlights the importance of standard grading systems and collaborating with market groups in minimizing quality loss.

AbstractATP‐binding cassette, superfamily G, member 2 (ABCG2) has been shown to play an important role in the development of ischemic stroke in European and African American populations. The aim of the present study is to test the hypothesis that there are associations betweenABCG2polymorphisms and ischemic stroke risk in a Chinese population. We conducted a case–control study including 967 participants with ischemic stroke and 939 stroke‐free controls. The rs2231137C > T and rs2231142G > T were genotyped using a TaqMan real‐time polymerase chain reaction assay. We found the rs2231137C > T and rs2231142G > T inABCG2were significantly associated with ischemic stroke (sex‐, age‐, BMI‐, SBP‐, DBP‐adjusted OR = 1.252; 95% CI, 1.035–1.515;P‐value = 0.021 and OR = 1.526; 95% CI, 1.085–2.146;P‐value = 0.015, respectively). By haplotype analyses, the haplotype T‐G still had a strongly significant association with ischemic stroke (OR = 0.806; 95% CI, 0.692–0.939;P‐value = 0.00568). Our findings identified the rs2231137C > T and rs2231142G > T polymorphisms of theABCG2as risk factors for ischemic stroke in a Chinese population.
