Authors: Carbone Valentina , Rouquet Aurélien , Roussat Christine 
Published: May 2018

PurposeThe growth of collaborative consumption is beginning to stimulate management research on this phenomenon. However, so far, few scholars have studied the logistics aspects related to these developments. The purpose of this paper is to develop a conceptual approach to the logistics at work in collaborative consumption.Design/methodology/approachThe authors adopt an inductive, exploratory research method, based on a content analysis involving 32 collaborative consumption initiatives screened through their websites and other secondary sources.FindingsBased on the way logistics is organized in these initiatives, the authors identify and describe four types of logistics: peer to peer, business, crowd, and open logistics.Practical implicationsThe paper makes recommendations for improving the management of collaborative consumption logistics.Originality/valueOur results enrich the literature about crowd practices and collaborative consumption by conceptualizing alternative roles played by logistics and revealing its specific organizational forms.
Student team integrating aspects of sustainability in practical design education
Authors: Ueda Edilson Shindi 
Published: May 2018

Purpose
The purpose of this paper is to describe and analyze the first experiences (activities, attitudes and inclinations) of an undergraduate student team with eco-design activities.

Design/methodology/approach
Undergraduate students of an industrial design course were invited to participate in the design project. The activities of students were carried out in the class titled in Japanese “Sogo Project” (Overall Project). The project is experimental learning based on pedagogical case studies that students propose practical designs with a sustainable approach.

Findings
According to the activities and attitudes of the student team, they showed interest in focusing on sustainable consumption and consequently leant towards a socio-cultural rather than a technological eco-design approach in their works. The barriers to design education for sustainable design were found, and the student team expressed that the available support tool during their design process was complex. They also expressed that the tool was not compatible with their academic skills and background.

Research limitations/implications
This paper has limited participants, resources, time and contextual scale. Few Japanese educators are skilled in eco-design, and eco-design modules are also poorly integrated into undergraduate and graduate industrial-design courses at Japanese universities.

Originality/value
The paper contributes to an initial discussion in the field of Japanese industrial-design education regarding the principles of and barriers to design education for sustainability.

Authors: Raposo Patricia , Martins João , Correia José , Salavessa Maria E. , Reis Cristina , Xavier José , Jesus Abilio M.P. de 
Published: May 2018

Purpose
The antique structures are part of the inheritance that our elders left, being important to preserve their memories. It is important to preserve, rehabilitate and restore the historic buildings protecting the cultural patrimony, attending to the actual comfort and habitability requirements. It is necessary to study the behaviour of the various elements that compose antique structures (masonry and wood) in order to develop assessment measures according to the characteristics of the original materials. The paper aims to discuss these issues.

Design/methodology/approach
An experimental campaign to characterize the mechanical behaviour of the wood of the roof of the “sequeiro” of “Quinta Lobeira de Cima”, a building from the twentieth century located in Minho, was carried out. The tested wood specimens are from two different species: chestnut and oak. Compression, tension and static flexion tests according to parallel to the grain direction were performed. Other parameters, such as density, moisture content and longitudinal modulus of elasticity in compression and in tension, were also obtained. The measurement of displacements was made with Digital Image Correlation (DIC).

Findings
The results of this study show the similarity between experimental and empirical values for the studied woods species.

Originality/value
This original study aimed at characterizing the mechanical properties using DIC of wood of the roof of the “sequeiro” of “Quinta Lobeira de Cima”, a building from the twentieth century located in Minho (Portugal). This study is part of master thesis of João Martins, an original research work.

Authors: Nujen Bella Belerivana , Halse Lise Lillebrygfjeld , Damm Rickard , Gammelsæter Hallgeir 
Published: May 2018

Purpose
Against the recent trend toward reversed global outsourcing, the purpose of this paper is to provide insights on how the internal process can be handled once the decision on reverse outsourcing has been made. The authors focus in particular on in-house knowledge and technology requirements.

Design/methodology/approach
To explore the topic at hand, the researchers conducted in-depth semi-structured interviews with five companies operating in two different industry sectors.

Findings
Reversed outsourcing accentuates challenges relating to retained knowledge. When embarking on reversed outsourcing, companies need to acknowledge the effort to revive and renew capabilities in order to perform technical operations and advanced manufacturing production.

Research limitations/implications
The research is based on case studies in a Scandinavian context. Further empirical research from other high-cost locations is needed to validate the findings.

Originality/value
Explorative qualitative research is scarce in the emergent literature on reversed outsourcing. The paper provides practical and theoretical insights into how to handle diminishing knowledge in companies that are re-evaluating their sourcing strategies. It adds a knowledge dimension within the emergent literature. A framework for key success factors and propositions is also provided.

Published: May 2018

PurposeThe purpose of this paper is to shed light on the changing pattern and characteristics of international financial flows in the emerging entrepreneurial ecosystems of Sub-Saharan Africa (SSA), provide a novel taxonomy to classify and analyze them, and discuss how such investments contribute to competence building and sustainable development.Design/methodology/approachIn an exploratory study, the authors analyze the characteristics of international venture capital investors and the start-ups receiving funding in Kenya and map their interaction. The authors proceed by developing a novel taxonomy, classifying investors according to their main rationales (for-profit-for-impact), and start-ups according to the locus of needs and markets addressed by the start-up (local-global) and the locus of the start-ups capacity and knowledge (local-global).FindingsThe authors observe a new type of mainly western investors who support innovative ideas in SSA by identifying and investing in domestically developed technical innovations with the potential to address global market needs. The authors find such innovations to be mainly developed at the intersect of global and local knowledge.Originality/valueThe authors shed light on the – up to now – under-researched emerging phenomenon of international high-tech investments in SSA, and develop a novel taxonomy of technology investments in low-income countries, guiding further research on the conditions, impact, practical, and policy implications of this new form of finance flows.
Examining the behavioral intention to participate in a CashWaqf-Financial Cooperative-Musharakah Mutanaqisahhome financing model
Authors: Zabri Mohd Zaidi Md , Mohammed Mustafa Omar 
Published: May 2018

PurposeThe purpose of this paper is to investigate the Malaysian homeowners’ intention to participate in the CashWaqf-Financial Cooperative-Musharakah Mutanaqisah(CWFCMM) home financing model using rigorous scale validation procedures.Design/methodology/approachAn adapted questionnaire with 26 items was administered to 382 academic and supporting staffs, postgraduate and undergraduate students in three states in Malaysia. The data were analyzed using exploratory factor analysis and confirmatory factor analysis with SPSS 21 and AMOS 21, respectively.FindingsThe results further support the parsimonious nature theory of planned behavior (TPB) with its three original construct of attitude, subjective norm, and perceived behavioral control and an additional construct of perceived cost advantages of the CWFCMM Model. A validated TPB scale with 24 items measured can be proposed to be used as an evaluative tool to assess the level to which the homeowners are interested to participate in the CWFCMM Model.Research limitations/implicationsThe modified TPB scale would also facilitate the identifications of factors that influence homeowners’ intention to opt for Islamic home financing (IHF) by non-bank Islamic financial institutions such as financial cooperative.Practical implicationsThe CWFCMM Model aims to harness the potential synergy between third-sector economy players such aswaqfand financial cooperatives in offering affordable IHF solution to potential homeowners.Social implicationsThe CWFCMM Model may enable the Malaysian homeowners to enjoy a more affordable IHF solution, thereby, among others, reducing the purchase and monthly repayment affordability of Malaysians.Originality/valueThere is a dearth of Islamic financial services selection studies, especially within the non-banking, Islamic financial services milieu. The CWFCMM Model, which has been developed by the authors, enriches the limited literature on this subject matter. It will also add value to understand how the customers would react to an alternative IHF provider.
The airline industry in South Africa: drivers of operational efficiency and impacts
Authors: Mhlanga Oswald , Steyn Jacobus , Spencer John 
Published: May 2018

Purpose
The airline industry is structurally challenged by its very nature, because of high overhead and capital costs. This is further exacerbated by macro-predictability and micro-uncertainty, thereby making it difficult for airlines in South Africa to attain operational efficiency. The purpose of this study is to identify drivers of operational efficiency and their impacts on airline performances in South Africa.

Design/methodology/approach
An extensive data collection using primary and secondary sources enabled the researchers to gather data on all the airlines operating in South Africa, for the period of 2012-2016, on a variety of parameters. A two-stage empirical analysis was carried out, which involved estimation of operational efficiencies during the first stage by using data envelopment analysis (DEA) and determination of performance drivers during the second stage by using a two-way random-effects generalised least squares regression and also a Tobit model.

Findings
From the study, it is clear that two structural drivers, namely, “aircraft size” and “seat load factor”, and two executional drivers, namely, “low cost business model” and “revenue hours per aircraft”, significantly impacted (p < 0.05) positively on airline efficiencies in South Africa. To improve efficiency, management should first concentrate on the drivers that can be changed in the short-term (executional drivers) and later focus on the drivers that require long-term planning (structural drivers). However, among the structural drivers, only “aircraft families” had a negative impact on airline efficiencies, whilst among executional drivers, only “block hours” negatively impacted on airline efficiencies.

Research limitations/implications
Despite the importance of this study, it is not free of limitations. Firstly, because of the small size of the industry, fewer airlines and lack of detailed data, the study could not consider other important factors such as optimal routing and network structure. Secondly, although non-aeronautical revenues have become increasingly important in airline management, they were not included in this study. Further studies may investigate the impact of these factors on airline efficiency.

Practical implications
The results have potential policy implications. Firstly, as the domestic airline market in South Africa is too small to operate with a smaller aircraft efficiently, airlines that intend to make use of smaller aircraft should first identify niche markets where they can have a route monopoly, such as SA Airlink. Secondly, as block time negatively affected airline efficiency, airlines can undertake schedule adjustments to reduce block time and thus improve technical efficiency.

Originality/value
This paper is a first attempt to identify drivers of operational efficiency in the airline industry in South Africa. The results indicate that DEA is a useful tool to identify factors impacting airline efficiency and could improve airline performances in South Africa.
Presenting a model of corporate entrepreneurship with corporate governance approach
Authors: Ziyae Babak 
Published: May 2018

Purpose
The purpose of this paper is to design a model of corporate entrepreneurship (CE) considering corporate governance in the brokerage industry.

Design/methodology/approach
The research method is qualitative using grounded theory as the method for research operation. The qualitative data were collected using an in-depth interview technique. Using snowball sampling method, 18 chief executive officers of Iranian brokerage listed in Iran’s Securities and Exchange organization were selected for the current study.

Findings
The findings of the study showed that CE at inbound, outbound and composition is defined as strategies that enhance corporate governance. Research findings also recommend that by using CE strategies corporate governance will be enhanced in the brokerage industry.

Research limitations/implications
Possibility of proper applying, deploying and implementing CE and its various methods will require the necessary fields and infrastructures in the considered organization. On the other hand, according to the research results, at inbound, outbound and composition levels, CE is defined as a practice or strategy that enhances corporate governance.

Practical implications
This study established that corporate governance in the Iranian brokerage firms is weak. The aforementioned firms do not have particular units to deal with stock market risks. The findings explain why some Iranian brokerage firms either collapsed or were facing financial distress. The research therefore recommends that Iranian brokerage firms should strengthen their governance structure and risk mitigation mechanisms. Therefore, CE practice facilitates the development of appropriate strategic actions for brokerage corporate success.

Originality/value
This study has been conducted due to the lack of theoretical literature in CE to deal with the ultimate goals of corporate governance in the brokerage industry.
The effects of e-marketing orientation on strategic business performance
Authors: Yousaf Zahid , Sahar Noor , Majid Abdul , Rafiq Amajad 
Published: May 2018

Purpose
The purpose of this paper is to investigate the impact of e-marketing orientation (EMO) on strategic business performance (SBP) in presence of e-trust.

Design/methodology/approach
Data were collected from CEOs, finance managers, IT managers, Policy makers, owners and Managing Directors of SMEs located in two big cities of Pakistan (Islamabad and Peshawar). Correlation, regression and bootstrap analysis was conducted to check the relationship among independent, mediating and dependent variables.

Findings
Based on empirical findings of the responses from managerial staff, it is suggested that strategic performance largely depends on EMO and e-trust.

Research limitations/implications
The authors recommend that further studies are required to test the propositions in longitudinal research design for achieving in-depth insights.

Practical implications
It has been observed that SMEs in developing countries pay less attention toward its strategic goals. This research discusses an implementation approach based on solid theoretical foundations to achieve the SBP.

Originality/value
This study tests e-trust as a mediator between EMO and SBP, therefore, makes a significant contribution to the literature of SMEs by focusing on the link between EMO, e-trust and SBP.
High‐definition frequency decomposition
Authors: Eckersley Adam John , Lowell James , Szafian Peter 
Published: May 2018

ABSTRACTSpectral decomposition is a widely used technique in analysis and interpretation of seismic data. According to the uncertainty principle, there exists a lower bound for the joint time–frequency resolution of seismic signals. The highest temporal resolution is achieved by a matching pursuit approach which uses waveforms from a dictionary of functions (atoms). This method, in its pure mathematical form can result in atoms whose shape and phase have no relation to the seismic trace. The high‐definition frequency decomposition algorithm presented in this paper interleaves iterations of atom matching and optimization. It divides the seismic trace into independent sections delineated by envelope troughs, and simultaneously matches atoms to all peaks. Co‐optimization of overlapping atoms ensures that the effects of interference between them are minimized. Finally, a second atom matching and optimization phase is performed in order to minimize the difference between the original and the reconstructed trace. The fully reconstructed traces can be used as inputs for a frequency‐based reconstruction and red–green–blue colour blending. Comparison with the results of the original matching pursuit frequency decomposition illustrates that high‐definition frequency decomposition based colour blends provide a very high temporal resolution, even in the low‐energy parts of the seismic data, enabling a precise analysis of geometrical variations of geological features.
Laboratory measurements of seismic attenuation and Young's modulus dispersion in a partially and fully water‐saturated porous sample made of sintered borosilicate glass
Authors: Chapman Samuel , Quintal Beatriz , Holliger Klaus , Baumgartner Lukas , Tisato Nicola 
Published: May 2018

ABSTRACTWe measured the extensional‐mode attenuation and Young's modulus in a porous sample made of sintered borosilicate glass at microseismic to seismic frequencies (0.05–50 Hz) using the forced oscillation method. Partial saturation was achieved by water imbibition, varying the water saturation from an initial dry state up to ∼99%, and by gas exsolution from an initially fully water‐saturated state down to ∼99%. During forced oscillations of the sample effective stresses up to 10 MPa were applied. We observe frequency‐dependent attenuation, with a peak at 1–5 Hz, for ∼99% water saturation achieved both by imbibition and by gas exsolution. The magnitude of this attenuation peak is consistently reduced with increasing fluid pressure and is largely insensitive to changes in effective stress. Similar observations have recently been attributed to wave‐induced gas exsolution–dissolution. At full water saturation, the left‐hand side of an attenuation curve, with a peak beyond the highest measured frequency, is observed at 3 MPa effective stress, while at 10 MPa effective stress the measured attenuation is negligible. This observation is consistent with wave‐induced fluid flow associated with mesoscopic compressibility contrasts in the sample's frame. These variations in compressibility could be due to fractures and/or compaction bands that formed between separate sets of forced‐oscillation experiments in response to the applied stresses. The agreement of the measured frequency‐dependent attenuation and Young's modulus with the Kramers–Kronig relations and additional data analyses indicate the good quality of the measurements. Our observations point to the complex interplay between structural and fluid heterogeneities on the measured seismic attenuation and they illustrate how these heterogeneities can facilitate the dominance of one attenuation mechanism over another.
Tarin, a Potential Immunomodulator and COX‐Inhibitor Lectin Found in Taro (Colocasia esculenta)
Authors: Pereira Patricia Ribeiro , Corrêa Anna Carolina Nitzsche Teixeira Fernandes , Vericimo Mauricio Afonso , Paschoalin Vânia Margaret Flosi 
Published: May 2018

AbstractTaro (Colocasia esculenta) corm is a rustic staple food, rich in small starch granules, fibers, and bioactive phytoconstituents such as flavonoids, alkaloids, sterols, tannins, phytates, micronutrients, and proteins, including tarin, a GNA‐related lectin. Tarin exhibits recognized biocide activities against viruses and insects, has antitumoral properties and is an immunomodulator molecule candidate. It has been isolated in highly purified form (>90%) from taro corms through low‐cost and single‐step affinity chromatography. It comprises 2‐domain 27 to 28 kDa protomer, posttranslational cleaved into 2 nonidentical monomers, 11.9 and 12.6 kDa, held by noncovalent binding. At least 10 tarin isoforms sharing over 70% similarity have been described. The monomers assume the β‐prism II fold, consisting of 3 antiparallel β‐sheets formed by 4 β‐strands each. Tarin exhibits an expanded‐binding site for complex and high‐mannose N‐glycan chains 49, 212, 213, 358, 465, and 477 found on cell surface antigens of viruses, insects, cancer, and hematopoietic cells, explaining its broad biological activities. Tarin may stimulate innate and adaptive immune responses, enabling hosts to recover from infections or immunosuppressed status inherent to several pathological conditions. In a murine model, tarin stimulates the in vitro and in vivo proliferation of total spleen and bone marrow cells, especially B lymphocytes. Granulocyte repopulation has also been demonstrated in long‐term mice bone marrow cell cultures. As a potential immunomodulator, tarin, administered to immunosuppressed mice, attenuated cyclophosphamide‐induced leukopenia. We propose a molecular model that unites the potential prophylactic and therapeutic action of tarin on hematopoietic and cancer cells, as a potential immunomodulator.
