Customers becoming creators: how firms leverage technology and consumers for new value
Authors: Dal Zotto Pierre , Colombero Sylvain , Pigni Federico , Haggège Meyer 
Published: July 2018

Purpose
The rapid development of information and communication technologies (ICTs) has facilitated consumers’ involvement in firms’ value creation processes through increasingly near real-time information exchanges. This strategic opportunity configures new forms of ICT-enabled collaboration between firms and consumers. Firms can now immediately react to consumers’ requests/complaints, having gained real-time visibility of consumers’ actions and behaviors. Despite the increasing deployment of ICT-enabled value co-creation projects, managers still poorly apprehend them as high-potential strategic initiatives.

Design/methodology/approach
This paper investigates this gap through a multiple qualitative case study based on 17 organizations that successfully implement ICT-based value co-creation initiatives, including Lego, Netflix and Blablacar.

Findings
This study identifies two dimensions of the ICTs’ value co-creation process, namely, the firms’ involvement and customers’ role, in this co-creation process. Through these dimensions, four ICT-based co-creation initiatives are observed and defined: community, customers’ contributions create the firms’ value proposition (FVP); customization, customers’ service consumption personalize FVP; reputation, customers’ contributions about the offered services completes the FVP; and sense, an algorithmic approach, designed to focus on learning from customers’ consumption tailors FVP.

Originality/value
This study advances a framework supporting managerial decision-making concerning the aptitude of co-creation initiatives to meet organizational goals. Managers may gain insight from its use especially in assessing emerging opportunities to engage consumers in the value creation process.
Political business cycles and economic growth in Africa
Authors: Iddrisu Abdul Ganiyu , Bokpin Godfred A. 
Published: July 2018

Purpose
The purpose of this paper is to understand both the incidence and the impact of the African political business cycle (PBC) in the light of a literature which has argued that, with major extensions of democracy since the 1990s, the cycle has both become more intense and has made African political systems more fragile. It answers two very important macroeconomic questions crucial to the validity of the opportunistic model. It, first, answers the question of whether election cycles contribute to money growth in the light of government expenditure, and second, whether election cycles have an effect on economic growth in the light of money supply.

Design/methodology/approach
The study employs data from 39 African countries from 1990 to 2014 to address these important empirical questions using panel regression techniques.

Findings
The paper found PBC to be present in Africa. It also found that such cycles do not translate to economic performance in African countries. The paper therefore indicates the need for African policy makers to take measures to eliminate or lessen the scale of PBCs.

Social implications
There are many ways in which today’s political choices affect future well-being. Recently, economists have concluded that we pass on the inflationary (or deflationary) consequences of current policies to the future generation.

Originality/value
This paper is unique in its approach to investigate the objectives.
A random effects multinomial logit model for the determinants of exit modes
Authors: Irfan Mohd , Saha Sarani , Singh Sanjay Kumar 
Published: July 2018

PurposeThe purpose of this paper is to examine the factors associated with three modes of firms’ exit (voluntary liquidation, involuntary liquidation and acquisition) in a mutually exclusive environment. In particular, three modes of exit are treated as independent events given that different causes and consequences exist for each exit mode. The data set is a panel of 4,408 US manufacturing firms spanning over the period 1976–1995.Design/methodology/approachThe discrete choice model is used to establish a relationship between modes of exit and a set of explanatory variables, which are specific to the firm, industry and macroeconomic conditions. Use of panel data encourages us to estimate a random effects multinomial logistic regression model, which allows exit modes as mutually exclusive events and at the same time controls the firm-specific unobserved heterogeneity in the sample.FindingsThe analysis suggests that the determinants of voluntary liquidation are age, size, profitability, technology intensity and inflation level. The determinants of involuntary liquidation are size, leverage, profitability and inflation level. For acquisition, determinants are age, size, advertising intensity, Tobin’sq, GDP growth, inflation level and interest rate. The findings suggest that exit modes have a different set of determinants and the scale of effects of some common determinants such as age, size and profitability differs between exit modes.Research limitations/implicationsThe analysis presented in this study relies on data from US manufacturing firms only. Thus, there is a need to explore the determinants of exit modes in other countries as well using the proposed econometric model.Practical implicationsThe findings presented in this paper are useful for managers and policymakers to design strategies/actions for avoiding particular mode of exit.Originality/valueThis study provides empirical evidence on the differences in factors associated with exit modes and confirms the existence of mutually exclusive nature of exit modes. Findings suggest that for future empirical studies on firm exit, the exit modes must be treated as a heterogeneous event.
Is exit tax a good idea for the taxman?
Authors: Dai Darong 
Published: July 2018

Purpose
The purpose of this paper is to study whether it is a rational choice for a tax authority to impose an exit tax on capitalists.

Design/methodology/approach
The tax authority chooses a lump-sum exit tax to maximize a weighted objective of expected tax revenue and expected tax horizon. The tax revene consists of capital income taxes and exit taxes. Capitalists are motivated by sustainable capital accumulation and hence maximize the terminal capital stock.

Findings
The author finds that the objective function of the tax authority is strictly increasing in the exit tax, which holds for extensions with sales tax, labor income tax or proportional exit tax, and hence equilibrium exit tax is equal to an exogenous upper bound.

Originality/value
To the author’s knowledge, no existing literature investigates this issue theoretically, and hence the current paper represents the first attempt. The author hopes this theoretical analysis can trigger related empirical studies.
Stimulating broadband adoption: state-owned companies versus tax exemptions – the Brazilian case
Authors: Baigorri Carlos M. , Maldonado Wilfredo L. 
Published: July 2018

Purpose
The purpose of this paper is to propose a new methodology to assess the economic and social impacts of policies to promote mass access to the internet in fixed broadband. The authors apply the methodology to the Brazilian broadband market.

Design/methodology/approach
For this purpose, municipal information concerning the provision of EILD is used, and then a stylized model of definition of service penetration based on information regarding the price, the distribution of income and the number of households served is proposed.

Findings
The results indicate that cost reduction policies are more effective than measures to promote competition through the introduction of state-owned enterprises in the telecommunication market for broadband service. On the other hand, the results also indicate that the federal and state governments face a dilemma between broadband policy and tax policy.

Originality/value
This is a new and original methodology to model the broadband market demand, which is useful to assess the impact of regulation policies in the sector as well as structural changes in that market.

Authors: Yogeshwaran Gayathri , Perera B.A.K.S. , Ariyachandra M.R. Mahendrini Fernando 
Published: July 2018

PurposeQuantity surveying education in Sri Lanka (SL) presently does not appear to be catering to the industry needs indicating that it may not be up to the expected standard. Hence, the purpose of this study is to identify the gap between the competencies of graduate quantity surveyors (QSs) and the competencies that industry in SL expects from them.Design/methodology/approachA hybrid approach was used, consisting of desk reviews, expert interviews and a questionnaire survey. A comparative analysis identifying differences between two competency levels was carried out.FindingsAnalysis reveals that competencies of graduate QSs in areas of cost planning, strategic planning, risk management, value management, life cycle cost analysis, sustainability, surveying and levelling, research and development, building surveying and business management are at levels higher than industry needs. However, majority of competencies are at levels lower than industry expectations.Research limitations/implicationsThis research was focused only on competencies of QSs who have successfully completed a quantity surveying degree programme accredited by Institute of QSs SL, Royal Institution of Chartered Surveyors, Australian Institute of QSs and Pacific Association of QSs. It excluded non-graduates’ competencies as they gain competencies only through work experience.Practical implicationsThis study revealed the need for designing quantity surveying degree programmes to cater to industry needs to ensure that graduates from these programmes are acceptable to the industry.Originality/valueThis study made an original contribution to knowledge by identifying the gap that currently exists between industry needs and programme outcomes of quantity surveying degree programmes, which could be invaluable when improving quantity surveying education in SL.
Role of culture in low carbon supply chain capabilities
Authors: Ambekar Sudhir , Prakash Anand , Patyal Vishal Singh 
Published: July 2018

PurposeThe purpose of this paper is to propose a low carbon culture (LCC) adoption model for gaining the right carbon capabilities by integrating the dimensions of flexibility or control and external or internal of competing values framework (CVF) with that of level of carbon emission (LCE).Design/methodology/approachThis study reviewed literature related to low carbon supply chain, CVF and carbon capabilities to synthesize currently available frameworks for assessing culture and carbon-related insights. Based on these insights, this study proposes the carbon culture adoption model and presents some research propositions.FindingsThis study has extended categorization of culture suggested in CVF from four categories to eight distinct categories by adding “LCE” as a third dimension. The new categories of carbon culture are: “Red,” “Antagonist,” “Obligatory,” “Early Adopter,” “Follower,” “Transitive,” “Pragmatist” and “Green.” This categorization of organizations would help in selecting appropriate low carbon practices (LCPs).Research limitations/implicationsThis study presents purely conceptual framework with some research propositions which needs to be empirically tested.Practical implicationsOrganizations can formulate right policies for low carbon capabilities based on the LCC of their supply chain.Originality/valueWith increasing awareness about environment across stakeholders, organizations around the world are under pressure to reduce their carbon footprints. The extent of reduction in carbon footprints depends on the right capabilities across the supply chain which in turn depends on selection of the right combination of LCPs based on the supply chain culture.
Business value of enterprise resource planning spending and scope
Authors: Ghobakhloo Morteza , Azar Adel , Tang Sai Hong 
Published: July 2018

Purpose
The purpose of this study is to contribute to the existing knowledge about the value of post-implementation Enterprise Resource Planning (ERP) system at the firm level.

Design/methodology/approach
A questionnaire-based survey was conducted to collect data from 217 Malaysian firms that successfully implemented ERP system. Data analysis was conducted with partial least squares-structural equation modeling and partial least squares multi-group analysis techniques.

Findings
Higher ERP spending and greater ERP scope in the post-implementation stage were associated with higher performance gains.

Research limitations/implications
Among other limitations, relying on a small sample size and cross-sectional data of this study and lack of generalizability of findings tend to have certain limitations. An interesting direction for future research would be to extend this study by conducting a multi-level analysis to understand how ERP spending and scope would affect the micro-level performance.

Practical implications
Non-financial performance gain is another valuable outcome of ERP implementation. The choice between in-house and off-the-shelf ERP systems will have dramatic impacts on the future profitability of firms. ERP risk management team and related practices during implementation phase result in a significantly higher financial gain in the post-implementation phase.

Originality/value
This study assesses the business value of ERP at the post-implementation phase while accounting for key contextual and managerial issues, a topic that has received little attention to date.
The application of biochar to screen printing liquid waste polluted land, its effect in soil, mustard greens to heavy metals (Fe, Cr)
Authors: Sujana I. Putu 
Published: July 2018

Purpose
The purpose of this paper is to analyse the screen printing liquid waste polluted soil physical, chemical and biological characteristics, with the unpolluted soil, and to analyse the application of some types of biochar towards the growth of mustard greens plants and the concentration of heavy metals Fe, Cr on the screen printing liquid waste polluted soil.

Design/methodology/approach
This research was conducted in a green house by using fully randomized design, split plot design pattern, with three replications. The main plot is the type of biochar, and the subplot is the dosage of biochar. The biochar consists of four types (B1 = chicken manure biochar, B2 = coconut shell biochar, B3 = rice hulls biochar and B4 = mahogany woods biochar). The dosage of biochar consists of four levels (D0 = control, D1 = 5 ton/hectare, D2 = 10 ton/hectare and D3 = 15 ton/hectare). The tested variable is being analysed by using analysis of variance (ANOVA).

Findings
The screen printing liquid waste polluted soil physical, chemical and biological characteristics analysis shows that the soil pH is neutral, a low C organic, a low N total, a high P, CEC and base saturation, while the texture is soft. The analysis results of rice hulls biochar physical, chemical and biological characteristics are quantitatively better in comparison with chicken manure biochar, coconut shell biochar and mahogany biochar. The quantitative application of rice hulls biochar15 ton/hectare dosage can increase the growth of mustard greens, and also, it recovers the soil characteristics by heavy metals total rate of 14.11 ppm Fe and 0.95 ppm Cr from the plant, while 209.05 ppm Fe and 4.12 ppm Cr were found in the soil.

Originality/value
This is one of few studies the biochar to screen printing liquid waste polluted lands. Currently, numerous kinds of chemical substances have been applied in a form of fertilizer and pesticide into the soil. Other activities like transporting the crop residues, and the contamination of irrigation water that is caused by screen printing liquid waste, have also affected the soil. It becomes degraded where the soil becomes compact and losses its nutrients, and it is containing heavy metals material that is toxic for plants. Biochar is applied into the polluted soil to improve the soil, which is hard to decompose and is long-lasting in the soil. These days, both the raw or ready food products are exposed to the heavy metals with a large and concerning number, especially in big cities which most of the soil is polluted.
Dref-3 yarn structure with plied staple fibrous core
Authors: Bhowmick Manik , Rakshit Arup Kumar , Chattopadhyay Sajal Kumar 
Published: July 2018

Purpose
Dref-3 friction spun core yarns produced using staple fibre yarn as the core, e.g. Jute core yarn wrapped with cotton fibre, have poorer mechanical properties compared to the core yarn itself. The purpose of this study was to understand the structure of such yarns, that will lead to the optimization of fibre, machine and process variables for production of better quality yarn from the Dref-3/3000 machines.

Design/methodology/approach
The Dref spinning trials were conducted following a full factorial design with six variables, all with two operative levels. The Dref-3 friction spun yarn, in which the core is a plied, twisted ring yarn composed of cotton singles and the sheath, formed from the same cotton fibres making the singles, has been examined. The structures have also been studied by using the tracer fibre technique.

Findings
It was observed that rather than depending on the plied core yarn, the tensile properties of the Dref-3 yarn are significantly determined by the parameters those affect the constituent single yarn tensile properties, i.e. the amount of twist and its twist direction, yarn linear density and the sheath fibre proportion used during the Dref spinning in making the final yarn. Further, when the twist direction of single yarn, double yarn and the Dref spinning false twisting are in the same direction, the produced core-sheath yarn exhibits better tensile properties.

Practical implications
The understanding of the yarn structure will lead to optimized production of all staple fibre core Dref spun yarns.

Social implications
The research work may lead to utilization of coarse and harsh untapped natural fibres to the production of value-added textile products.

Originality/value
Though an earlier research has reported the effects of sheath fibre fineness and length on the tensile and bending properties of Dref-3 friction yarn, the present study is the first documented attempt using the tracer fibre technique to understand Dref-3 yarn structure with plied staple fibrous core.
Physiological and pathophysiological role of reactive oxygen species and reactive nitrogen species in the kidney
Authors: Ishimoto Yu , Tanaka Tetsuhiro , Yoshida Yoko , Inagi Reiko 
Published: July 2018

SummaryEnd‐stage renal disease is a leading cause of morbidity and mortality worldwide. The prevalence of the disease and the number of patients who receive renal replacement therapy are expected to increase in the next decade. Accumulating evidence suggests that chronic hypoxia in the tubulointerstitium represents the final common pathway to end‐stage renal failure, and that reactive oxygen species (ROS) and reactive nitrogen species (RNS) are the key players in kidney injury. However, ROS and RNS that exceed the physiological levels associated with the pathophysiology of most kidney diseases. The molecules that comprise ROS and RNS play an important role in regulating solute and water reabsorption in the kidney, which is vital for maintaining electrolyte homeostasis and the volume of extracellular fluid. This article reviews the physiological and pathophysiological role of ROS and RNS in normal kidney function and in various kidney diseases.

SummaryThis microbiological survey was performed to determine the conservation state of a mummy in the Slovak castle of Krásna Hôrka and its surrounding environment. Culture‐dependent identification was coupled with biodegradation assays on keratin, gelatin and cellulose. Next Generation Sequencing (NGS) using Illumina platform was used for a deeper microbial investigation. Three environmental samples were collected: from the glass of the sarcophagus, from the air inside it, and from the air of the chapel where the mummy is located. Seven different samples were taken from mummy's surface: from the left ear, left‐hand palm, left‐hand nail, left instep, right hand, abdomen and mineral crystals embedded within the skin. Three internal organ samples, from the lung, pleura and stomach, were also included in this study. Together, the culture‐dependent and culture‐independent analyses revealed that the bacterial communities present had fewer taxa than the fungal ones. The mycobiome showed the largest variability and included Epicoccum nigrum, Penicillium spp., Alternaria spp., Aspergillus spp., Cladosporium spp. and Aureobasidium pullulans; many other Ascomycota and Basidiomycota genera were detected by NGS. The most interesting results came from the skin mineral crystals and the internal organs. The hydrolytic assays revealed those microorganisms which might be considered dangerous ‘mummy pathogens’. © 2018 Society for Applied Microbiology and John Wiley & Sons Ltd
Novel phage–host interactions and evolution as revealed by a cyanomyovirus isolated from an estuarine environment

Published: July 2018

SummaryCyanophages are thought to affect the community structure, population dynamics, metabolic activity and evolution of picocyanobacteria and to impact the biogeochemical cycling in aquatic ecosystems. Here, we report an estuarine Synechococcus phage, S‐CBWM1, which represents a novel viral lineage and exhibits interesting genetic features related to phage–host interactions and evolution. S‐CBWM1 encapsidates four virion‐associated proteins related to cellular metabolic regulation. Several novel auxiliary metabolic genes related to multidrug efflux, cell wall and capsule synthesis or modifications were also identified. In addition, the presence of the largest number of tRNA genes hitherto found in a phage genome may contribute to the translation efficiency of unique genes. These genomic and proteomic features of S‐CBWM1 suggested phage–host interactions involved in adaptation to eutrophic estuarine environments. Phylogenetic and metagenomic analysis of the polγ gene in the S‐CBWM1 genome provided new insights into the evolutionary path of mitochondrial DNA polymerase gamma. The S‐CBWM1 psbA contains two group I introns, representing the first instance of multiple introns within psbA from phage. The isolation of S‐CBWM1 reveals that estuarine ecosystems contain evolutionarily novel cyanophages that drive unique phage–host interactions.
