Authors: Kayest Mamta , Jain Sanjay Kumar 
Published: June 2019

PurposeDocument retrieval has become a hot research topic over the past few years, and has been paid more attention in browsing and synthesizing information from different documents. The purpose of this paper is to develop an effective document retrieval method, which focuses on reducing the time needed for the navigator to evoke the whole document based on contents, themes and concepts of documents.Design/methodology/approachThis paper introduces an incremental learning approach for text categorization using Monarch Butterfly optimization–FireFly optimization based Neural Network (MB–FF based NN). Initially, the feature extraction is carried out on the pre-processed data using Term Frequency–Inverse Document Frequency (TF–IDF) and holoentropy to find the keywords of the document. Then, cluster-based indexing is performed using MB–FF algorithm, and finally, by matching process with the modified Bhattacharya distance measure, the document retrieval is done. In MB–FF based NN, the weights in the NN are chosen using MB–FF algorithm.FindingsThe effectiveness of the proposed MB–FF based NN is proven with an improved precision value of 0.8769, recall value of 0.7957,F-measure of 0.8143 and accuracy of 0.7815, respectively.Originality/valueThe experimental results show that the proposed MB–FF based NN is useful to companies, which have a large workforce across the country.
Enabling and leveraging ambidexterity: influence of strategic orientations and knowledge stock
Authors: Ramachandran Indu , Lengnick-Hall Cynthia A. , Badrinarayanan Vishag 
Published: June 2019

PurposeThis paper aims to develop and empirically test a framework articulating the effects of strategic orientations (entrepreneurial orientation and market orientation) on leveraging ambidexterity. Further, the paper examines the moderating effects of knowledge stock (market knowledge and technological knowledge) on the relationship between ambidexterity and firm performance to gain additional insights into how ambidexterity can be leveraged in an organization.Design/methodology/approachData were obtained from CEOs (or equivalent members of the top management team) of 234 firms. The adequacy and psychometric properties of all measures were evaluated and purified using a maximum likelihood confirmatory factor analysis (CFA), and the hypotheses were tested using ordinary least squares (OLS). A number of post hoc tests were conducted to develop a nuanced understanding of proposed effects.FindingsWhile both strategic orientations enhance an organization’s ability to be ambidextrous, results show that some types of knowledge stocks facilitate, whereas other types hinder the influence of ambidexterity on firm performance.Research limitations/implicationsBoth strategic orientations enable ambidexterity; however, technological knowledge stock impedes the effect of ambidexterity on firm performance, while market knowledge stock enhances this relation. Cross-sectional nature of the study imposes limitations on causal inferences.Practical implicationsDifferent strategic orientations provide organizations with a cluster of knowledge acquisition and utilization capabilities that enable ambidexterity. However, organizations should be wary of indiscriminate accumulation of knowledge stocks – while certain types enhance the effect of ambidexterity, others may create competency traps or core rigidities and inhibit the effect of ambidexterity.Originality/valueThis study integrates related, yet hitherto fragmented, research streams to demonstrate the interconnectedness between strategic orientations, ambidexterity and existing knowledge stock. Several theoretical and managerial implications are identified.
A whole-school approach to supporting children and young people’s mental health
Authors: Glazzard Jonathan 
Published: June 2019

Purpose
Supporting the mental health of children and young people is a global priority. The issue is not specific to England. However, evidence suggests that one in ten children and young people in England has a mental health need. This represents approximately three students in every classroom. The purpose of this paper is to highlight the role of schools in supporting children and young people’s mental health. Whilst the paper acknowledges that teachers are not trained health professionals, it is argued that a whole-school approach to mental health can support individuals in schools to remain mentally healthy. The elements of a whole-school approach are identified and discussed and some of the challenges in relation to implementation are considered. Critical to the development of a whole-school approach is the commitment from the school leadership team to promoting student and staff wellbeing.

Design/methodology/approach
This is a policy paper not an empirical study.

Findings
This paper has outlined the policy context in the UK in relation to children and young people’s mental health. It has addressed the risk and protective factors which can cause or mitigate against mental ill health and it has outlined the elements of a whole-school approach to mental health.

Originality/value
This paper explores the contribution that schools can make to supporting students’ mental health. There is limited research which addresses mental health in young people from a non-therapeutic angle.
Motivation to use big data and big data analytics in external auditing
Authors: Dagilienė Lina , Klovienė Lina 
Published: June 2019

Purpose
This paper aims to explore organisational intentions to use Big Data and Big Data Analytics (BDA) in external auditing. This study conceptualises different contingent motivating factors based on prior literature and the views of auditors, business clients and regulators regarding the external auditing practices and BDA.

Design/methodology/approach
Using the contingency theory approach, a literature review and 21 in-depth interviews with three different types of respondents, the authors explore factors motivating the use of BDA in external auditing.

Findings
The study presents a few key findings regarding the use of BD and BDA in external auditing. By disclosing a comprehensive view of current practices, the authors identify two groups of motivating factors (company-related and institutional) and the circumstances in which to use BDA, which will lead to the desired outcomes of audit companies. In addition, the authors emphasise the relationship of audit companies, business clients and regulators. The research indicates a trend whereby external auditors are likely to focus on the procedures not only to satisfy regulatory requirements but also to provide more value for business clients; hence, BDA may be one of the solutions.

Research limitations/implications
The conclusions of this study are based on interview data collected from 21 participants. There is a limited number of large companies in Lithuania that are open to co-operation. Future studies may investigate the issues addressed in this study further by using different research sites and a broader range of data.

Practical implications
Current practices and outcomes of using BD and BDA by different types of respondents differ significantly. The authors wish to emphasise the need for audit companies to implement a BD-driven approach and to customise their audit strategy to gain long-term efficiency. Furthermore, the most challenging factors for using BDA emerged, namely, long-term audit agreements and the business clients’ sizes, structures and information systems.

Originality/value
The original contribution of this study lies in the empirical investigation of the comprehensive state-of-the-art of BDA usage and motivating factors in external auditing. Moreover, the study examines the phenomenon of BD as one of the most recent and praised developments in the external auditing context. Finally, a contingency-based theoretical framework has been proposed. In addition, the research also makes a methodological contribution by using the approach of constructivist grounded theory for the analysis of qualitative data.
Non-audit fees and auditor independence: Nigerian evidence
Authors: Onulaka Paul Nnamdi , Shubita Moade Fawzi , Combs Alan 
Published: June 2019

Purpose
This study aims to investigate the extent to which the provision of non-audit services (NAS) by external auditors to audit clients affects auditors’ independence and the audit expectation gap in Nigeria.

Design/methodology/approach
The study adopts an interpretivist approach. In total, 30 semi-structured, face-to-face interviews were conducted to explore the views expressed by audit partners and pension fund managers in Nigeria; group responses were evaluated and presented separately. After transcribing the interview audio recordings, a thematic data analysis of the two groups’ responses was performed.

Findings
Interpretation of the interview responses indicates that the provision of NAS by audit firms to their audit clients is regarded by auditors as a matter of economic necessity. Nevertheless, it is also perceived as impeding auditors’ independence and increasing the gap between the auditor and public expectations.

Practical implications
This study contributes to the debate surrounding the need for an independent body to oversee auditing standard setting distinct from the current practice to enhance transparency.

Originality/value
A qualitative analysis of the nuanced responses obtained from the semi-structured interviews reveals starkly the perceived economic pressures on auditors to accept non-audit work. Moreover, it endorses the regulation to restrict non-audit work in support of a sustainable fee level for an independent audit.
Islamic hedging for pilgrimage funds: case of Indonesia
Authors: Ismal Rifki , Septiana Nurul Izzati 
Published: June 2019

Purpose
The demand for Saudi Arabian real (SAR) is very high in the pilgrimage (hajj) season while the authority, unfortunately, does not hedge the hajj funds. As such, the hajj funds are potentially exposed to exchange rate risk, which can impact the value of hajj funds and generate extra cost to the pilgrims. The purpose of this paper is to conduct simulations of Islamic hedging for pilgrimage funds to: mitigate and minimize exchange rate risk, identify and recommend the ideal time, amount and tenors of Islamic hedging for hajj funds, estimate cost saving by pursuing Islamic hedging and propose technical and general recommendations for the authority.

Design/methodology/approach
Forward transaction mechanism is adopted to compute Islamic forward between SAR and Rupiah (Indonesian currency) or IDR. Findings – based on simulations, the paper finds that: the longer the Islamic hedging tenors, the better is the result of Islamic hedging, the decreasing of IDR/USD is the right time to hedge the hajj funds and, on the other hand, the IDR/SAR appreciation is not the right time to hedge the hajj funds.

Findings
Based on simulations, the paper finds that: the longer the Islamic hedging tenors, the better is the result of Islamic hedging, the decreasing of IDR/USD is the right time to hedge the hajj funds and, on the other hand, the IDR/SAR appreciation is not the right time to hedge the hajj funds.

Research limitations/implications
The research suggests the authority to (and not to) hedge the hajj fund, depending on economic conditions and market indicators. Even though the assessment is for the Indonesian case, other countries maintaining hajj funds might also learn from this paper.

Originality/value
To the best of author’s knowledge, this is the first paper in Indonesia that attempts to simulate the optimal hedging of hajj funds.
Financial constraints and the interdependence of corporate financial decisions
Authors: Kirch Guilherme , Terra Paulo Renato 
Published: June 2019

Purpose
This paper aims to examine the interdependence of financial decisions (investment, financing, dividends and cash-holding) under financial constraints.

Design/methodology/approach
The authors specify and estimate a system of simultaneous equations with panel data and firm fixed effects by three-stage least squares in a sample of firms from 62 countries from 1996 to 2010.

Findings
The main findings largely corroborate previous studies regarding the interdependence of financial decisions. The authors also find evidence suggesting that financial constraints have a major impact on firms’ financial decisions. The results also suggest that financial constraints manifest themselves in virtually all firms, indicating that such constraints are a matter of degree and not of kind.

Research limitations/implications
Implications regarding the impact of cash flows on investment and cash-holding decisions are only partially confirmed.

Practical implications
The results are consistent with the hypothesis that financial constraints distort the financial policies of firms. For the purpose of formulating policies that reduce these distortions, the authors emphasize the role of the availability of internal funds and the recoverable fraction of assets in easing financial constraints, thus allowing for greater investment on the part of firms.

Social implications
The results suggest that regulators should promote policies that reduce the dependence of corporate investment on internally generated cash flows.

Originality/value
Unlike previous studies, the authors account for the direct impact endogenous variables could have on each other. In addition, they explore the impact of each country’s particular legal environment on the pledgeability of assets at the company level.
Influence of demographics and motivational factors on US consumer clothing and shoes disposal behavior
Authors: Rezaei Arangdad Shaghayegh , Thoney-Barletta Kristin , Joines Jeff , Rothenberg Lori 
Published: June 2019

Purpose
The purpose of this paper is to study clothing and shoes disposal behavior of US consumers in an attempt to understand how to divert more clothing and shoes from the landfill.

Design/methodology/approach
A survey was administered to 209 consumers from the general US population. The survey includes questions on demographics, methods of disposal and factors that motivate or prevent consumers from choosing methods other than throwing unwanted clothing in the trash.

Findings
Analysis of demographic data from the survey indicates that gender, income, marital status, living arrangement and type of dwelling have an effect on whether consumers recycle textiles. Other survey results indicate that helping factors are more influential in motivating consumers to recycle clothing and shoes than economic factors. The condition of clothes and shoes and lack of awareness are the most prominent reasons preventing consumers from recycling more textiles. The results also show that there are statistically significant differences between households with and without children when it comes to disposing adults’ clothing and shoes.

Originality/value
These results may help policymakers who want to motivate consumers to recycle or develop recycling programs.
A design for additive manufacturing case study: fingerprint stool on a BigRep ONE
Authors: Novak James I. , O’Neill Jonathon 
Published: June 2019

Purpose
This paper aims to present new qualitative and quantitative data about the recently released “BigRep ONE” 3 D printer led by the design of a one-off customized stool.

Design/methodology/approach
A design for additive manufacturing (DfAM) framework was adopted, with simulation data iteratively informing the final design.

Findings
Process parameters can vary manufacturing costs of a stool by over AU$1,000 and vary print time by over 100 h. Following simulation, designers can use the knowledge to inform iteration, with a second variation of the design being approximately 50 per cent cheaper and approximately 50 per cent faster to manufacture. Metrology data reveal a tolerance = 0.342 per cent in overall dimensions, and surface roughness data are presented for a 0.5 mm layer height.

Research limitations/implications
Led by design, this study did not seek to explore the full gamut of settings available in slicing software, focusing predominantly on nozzle diameter, layer height and number of walls alongside the recommended settings from BigRep. The study reveals numerous areas for future research, including more technical studies.

Practical implications
When knowledge and techniques from desktop 3 D printing are scaled up to dimensions measuring in meters, new opportunities and challenges are presented for design engineers. Print times and material costs in particular are scaled up significantly, and this study provides numerous considerations for research centers, 3 D printing bureaus and manufacturers considering large-scale fused filament fabrication manufacturing.

Originality/value
This is the first peer-reviewed study involving the BigRep ONE, and new knowledge is presented about the practical application of the printer through a design-led project. Important relationships between material volume/cost and print time are valuable for early adopters.
Aquatic and terrestrial resources are not nutritionally reciprocal for consumers
Authors: Twining Cornelia W. , Brenna J. Thomas , Lawrence Peter , Winkler David W. , Flecker Alexander S. , Hairston Nelson G. 
Published: June 2019

Abstract

Aquatic and terrestrial ecosystems are connected through reciprocal fluxes of energy and nutrients that can subsidize consumers. Past research on reciprocal aquatic–terrestrial subsidies to consumers has generally focused on subsidy quantity while ignoring major differences in the nutritional composition of aquatic and terrestrial resources. Because aquatic resources contain substantially more highly unsaturated omega‐3 fatty acids (HUFAs) than terrestrial resources, aquatic subsidies may play a unique role by supplying these critical compounds to both aquatic and terrestrial consumers.

Here, we first characterized nutritional quality in terms of HUFA content in aquatic and terrestrial insect prey. We then used bulk stable isotope analyses to estimate subsidy use by stream and riparian consumers coupled with compound‐specific stable isotope analyses, which allowed us to document consumer HUFA sources. Finally, in order to understand the nutritional importance of aquatic‐derived HUFAs for riparian consumers, we conducted manipulative diet experiments on Eastern Phoebe (Sayornis phoebe) chicks in the laboratory.

Aquatic insects were significantly enriched in HUFAs, mainly in terms of eicosapentaenoic acid (EPA), compared with terrestrial insects. Stream fishes relied mainly upon aquatic resources, while insectivorous birds varied in their use of aquatic subsidies across sites. However, like stream fishes, Eastern Phoebe chicks received HUFAs from aquatic insects, even when they were heavily reliant upon terrestrial insects for their overall diet. In the laboratory, dietary HUFAs, such as those supplied by aquatic insects, increased the growth rate and condition of Eastern Phoebe chicks.

This study demonstrates that aquatic and terrestrial subsidies are not nutritionally reciprocal from the perspective of consumers because aquatic resources are the main source of critical fatty acids for both stream and riparian consumers. It also confirms previous findings on the nutritional importance of HUFAs for riparian birds, demonstrating that an insectivorous riparian lifestyle influences avian nutritional needs. Finally, our findings raise the possibility that birds and other riparian insectivores may experience nutritional mismatches with terrestrial prey if they do not have access to high‐quality aquatic subsidies as a consequence of aquatic habitat degradation or shifts in consumer and resource phenology.

Organic farming positively affects honeybee colonies in a flower‐poor period in agricultural landscapes
Authors: Wintermantel Dimitry , Odoux Jean‐François , Chadœuf Joël , Bretagnolle Vincent 
Published: June 2019

Abstract

Conventional farming has been implicated in global biodiversity and pollinator declines and organic farming is often regarded as a more ecological alternative. However, the effects of organic farming on honeybees remain elusive, despite honeybees’ importance as pollinators of crops and wild plants.

Using 6 years of data from a large‐scale study with fortnightly measurements of honeybee colony performance traits (10 apiaries per year distributed across a 435 km2‐large research site in France), we related worker brood area, number of adult bees and honey reserves to the proportions of organic farmland in the surroundings of the hives at two spatial scales (300 m and 1,500 m).

We found evidence that, at the local scale, organic farming increased both worker brood production and number of adult bees in the period of flower scarcity between the blooms of oilseed rape and sunflower (hereafter ‘dearth period’). At the landscape scale, organic farming increased honey reserves during the dearth period and at the beginning of the sunflower bloom.

The results suggest that worker brood development benefitted from organic farming mostly through a more diverse diet due to an increase in the availability of diverse pollen sources in close proximity of their hives. Reduced pesticide drift may have additionally improved bee survival. Honey reserves were possibly mostly affected by increased availability of melliferous flowers in foraging distance.

Synthesis and applications. Organic farming increases honeybee colony performance in a period of resource scarcity, likely through a continuous supply of floral resources including weeds, cover crops and semi‐natural elements. We demonstrate how worker brood area increases in the critical dearth period (between the blooms of oilseed rape and sunflower). This has previously been linked to winter colony survival, suggesting that organic farmland may mitigate repercussions of intensive farming on colony vitality. We conclude that organic farming benefits a crucial crop pollinator with potential positive implications for agriculture in the wider landscape.
Decoupling of nutrient cycles in a Eucalyptus woodland under elevated CO2
Authors: Ochoa‐Hueso Raúl , Piñeiro Juan , Power Sally A. 
Published: June 2019

Abstract

Elevated atmospheric [CO2] (eCO2) is currently altering nutrient cycling and availability in ecosystems worldwide. If the availabilities and turnover rates of macro‐ and micronutrients are differentially affected, then nutrient cycles may become out of sync (i.e., decoupled).

We evaluated the impacts of 3 years of eCO2 (550 µmol CO2/mol) on the availability, stability and coupling of eleven essential macro and micronutrients in a mature, P‐limited Eucalyptus woodland from Eastern Australia (EucFACE).

Despite increases in N and P availability in the first 18 months of study, nutrient availabilities and their stoichiometric ratios were unaffected by eCO2 across the study period (26–57 months of experimental duration). In contrast, the stability of nutrient availability increased under eCO2, which was concomitant with a reduction in the degree of biogeochemical coupling.

Synthesis. We demonstrate that macro‐ and micro‐nutrient cycles can quickly become out of sync (i.e., decoupled) under eCO2 in a low‐nutrient Australian eucalypt woodland, despite the lack of consistent effects on nutrient availability; such decoupling of nutrient cycles may have unpredicted consequences in terms of ecosystem functioning under the widely assumed positive relationship between biogeochemical coupling and ecosystem functioning.
