Equity-oriented design in open education
Authors: Kalir Jeremiah Holden 
Published: November 2018

Purpose
The purpose of this paper is threefold: to describe the equity-oriented design of a publicly accessible and openly networked computer-supported collaborative learning (CSCL) initiative that has supported educator discussion about equity topics; to identify design principles for equity-oriented design in open education; and to propose a model for the design of open learning initiatives that are mutually committed to educational equity and educational openness.

Design/methodology/approach
This paper draws from design-based research methodology, specifically design narrative and the worked example. The paper is one response to the need for more “designerly work” in the learning sciences, generally, and more specifically in domains such as CSCL.

Findings
Four design principles are identified that informed the equity-oriented creation and iteration of the Marginal Syllabus, an open CSCL initiative: leveraging the open web, fostering multi-stakeholder partnerships, working with open content and engaging professional learning as an open practice. This paper also advances the open palimpsests model for equity-oriented design in open education. The model integrates design principles to assist CSCL and open education designers and researchers in creating or iterating projects to be more equity-oriented learning opportunities.

Originality/value
This paper’s design narrative identifies Marginal Syllabus design principles and advances the open palimpsests model for equity-oriented design in open education. The design narrative demonstrates how critical perspectives on the relationship between equity and digital technology can encourage collaboration among diverse project stakeholders, attune to the dynamics of power and agency and respond to the worldly needs of partners and participants.
Spatial data managements in indoor environments
Authors: Alamri Sultan 
Published: November 2018

Purpose
With the rapid development of the indoor spaces positioning technologies such as the radio-frequency identification (RFID), Bluetooth and WI-FI, the locations of indoor spatial objects (static or moving) constitute an important foundation for a variety of applications. However, there are many challenges and limitations associated with the structuring and querying of spatial objects in indoor spaces. The purpose of this study is to address the current trends, limitations and future challenges associated with the structuring and querying of spatial objects in indoor spaces. Also it addresses the related features of indoor spaces such as indoor structures, positioning technologies and others.

Design/methodology/approach
In this paper, the author focuses on understanding the aspects and challenges of spatial database managements in indoor spaces. The author explains the differences between indoor spaces and outdoor spaces. Also examines the issues pertaining to indoor spaces positioning and the impact of different shapes and structures within these spaces. In addition, the author considers the varieties of spatial queries that relate specifically to indoor spaces.

Findings
Most of the research on data management in indoor spaces does not consider the issues and the challenges associated with indoor positioning such as the overlapping of Wi-Fi. The future trend of the indoor spaces includes included different shapes of indoors beside the current 2D indoor spaces on which the majority of the data structures and query processing for spatial objects have focused on. The diversities of the indoor environments features such as directed floors, multi-floors cases should be considered and studied. Furthermore, indoor environments include many special queries besides the common ones queries that used in outdoor spaces such as KNN, range and temporal queries. These special queries need to be considered in data management and querying of indoor environments.

Originality/value
To the best of the author’s knowledge, this paper successfully addresses the current trends, limitations and future challenges associated with the structuring and querying of spatial objects in indoor spaces.
Modelling SME e-commerce with IMAES
Authors: Sanchez-Torres Javier A. , Juarez-Acosta Fernando 
Published: November 2018

PurposeThere are several studies about the adoption of e-commerce for small-to-medium enterprises (SMEs) that separately, and in a dispersed manner, examine different theoretical approaches. The purpose of this paper is to unify a set of variables to form an integrated model of measurement of the adoption of e-commerce for SMEs.Design/methodology/discussionBased on an extensive review of empirical studies focused on the adoption of e-commerce in SMEs, a grouped and integrated model of e-commerce among SMEs was constructed. It was built upon the methodology of psychometrics and was subsequently statistically tested for reliability and validity. A broad study has not been carried out. Thus, the small sample size does not allow the estimation of this model’s predictability.FindingsThis paper proposes a final model, comprising 14 variables (82 items), grouping the significant effects of e-commerce adoption.Originality/valueThis tool is feasible, offering an initial model enabling detailed examination of variables affecting the adoption of e-commerce in SMEs. It contributes significantly to the development of this line of research.
Home-state attachment and its effects
Authors: Thakor Mrugank , Reid Susan , Chen Rui 
Published: November 2018

Purpose
Many studies have investigated consumers’ loyalty to businesses situated in the local area, in the community, the region or in the same country. However, the effect of loyalty to the state in which the consumer resides has received little attention. This paper aims to propose the concept of home-state attachment (HSA) and develop models of its antecedents and its effects on criterion variables such as loyalty to local business.

Design/methodology/approach
After refinement of the measure of HSA, the authors conduct two studies (n = 202 and n = 201) among residents of two different Canadian provinces (states). They estimate the models, which include both formative and reflective indicators, using structural equation modeling.

Findings
The results of both studies show that HSA can be distinguished from related constructs like consumer ethnocentrism (CET). HSA has a strong effect on loyalty to local businesses, independent of the effect of CET, testifying to its importance. HSA also affects other criterion variables, with loyalty to local business playing a mediational role.

Originality/value
This paper shows that HSA, a social-identity-based motivation for local patronage, is an important but largely overlooked determinant of loyalty to local businesses. The robustness of the results over two studies suggests that appeals to consumers based on this motivation may enhance the effectiveness of marketing programs.
Literature practices: processes leading up to a citation
Authors: Klitzing Nikolai , Hoekstra Rink , Strijbos Jan-Willem 
Published: November 2018

Purpose
Literature practices represent the process leading up to the citation of a source, and consist of the selection, reading and citing of sources. The purpose of this paper is to explore possible factors that might influence researchers during this process and discover possible consequences of researchers’ citation behaviours.

Design/methodology/approach
In this exploratory study, various factors which could influence literature practices were explored via a questionnaire amongst 112 researchers. Participants were first authors of articles published in 2016 in one of five different journals within the disciplines of experimental psychology, educational sciences and social psychology. Academic positions of the participants ranged from PhD student to full professor.

Findings
Frequencies and percentages showed that researchers seemed to be influenced in their literature practices by various factors, such as editors suggesting articles and motivation to cite. Additionally, a high percentage of researchers reported taking shortcuts when citing articles (e.g. using secondary citations and reading selectively). Logistic regression did not reveal a clear relationship between academic work experience and research practices.

Practical implications
Seeing that researchers seem to be influenced by a variety of factors in their literature practices, the scientific community might benefit from better citation practices and guidelines in order to provide more structure to the process of literature practices.

Originality/value
This paper provides first insights into researchers’ literature practices. Possible reasons for problems with citation accuracy and replicating research findings are highlighted. Opportunities for further research on the topic of citation behaviours are presented.
Economic assessment of bioethanol production from maize in South Africa
Authors: Ndokwana Ayanda , Fore Stanley 
Published: November 2018

PurposeThis research investigated the economic feasibility of using maize as feedstock to produce bioethanol in South Africa. The purpose of the study was to generate economic data from a maize-fed bioethanol plant and use it to perform a comparative analysis between the profitability that is generated by the maize exports to Southern African Development Community (SADC) countries and the profitability generated by the bioethanol plant in South Africa.Design/methodology/approachThis study used a combination of qualitative and quantitative methods to gather data. The mixed method approach was chosen owing to the nature of the study which required an analysis of qualitative and quantitative data in order to achieve its objectives.FindingsThe findings from a qualitative instrument indicated that a majority of respondents were in favour of the decision of excluding maize for bioethanol production made by the South African Government. Findings from quantitative analysis revealed that the profitability of the bioethanol plant was largely influenced by the prices of feedstock and bioethanol.Research limitations/implicationsThis research was a deterministic feasibility study which ignores the risk associated with price fluctuation of raw materials and products. A probabilistic feasibility study was recommended (Monte Carlo simulation). Such economic data can also help policymakers and investors to make informed decisions.Originality/valueThe study recommended the need to produce bioethanol from the maize cultivated in available arable soils in South Africa, thus alleviating the cost burden of importing oil and obnoxious environmental effects.
Propaganda as marketing
Authors: Gardeström Elin 
Published: November 2018

Purpose
This study aims to analyze the use of two concepts, propaganda and advertisement, in two areas of Swedish society during the 1930s; first, their use by the advertisement business, and second, their use by the Swedish Cooperative Union and Wholesale Society.

Design/methodology/approach
By adopting a perspective of conceptual history, inspired by Reinhart Koselleck, the author is trying to pinpoint the meanings that were ascribed to these concepts in a 1930s context, the interdependency between these concepts and other keywords that were used in connection with them.

Findings
The study reveals how the ambiguous and synonymous use of these concepts served different purposes in the two fields of study. In the 1930s, propaganda was a key concept of communication and was used in manifold ways for selling goods and disseminating ideas. Propaganda was used to explain the newly introduced American marketing terminology. During the 1930s, the field of advertisement was trying to change what previously had been labeled as “idea propaganda” into “advertisement.” The ambiguous use of concepts made it possible for the Swedish Cooperative Union and Wholesale Society to combine advertisement for their produced goods with disseminating ideas of the cooperative ideology. The concepts of enlightenment (upplysning) and propaganda were crucial to hold together the ideological and commercial parts of the cooperative movement.

Originality/value
The interaction of meanings between commercial and political concepts is rarely researched in conceptual history or marketing history, which this article advocates to be an important field of study.
Boundary conditions for the emergence of relational trust among exporters and importers
Authors: Ceyhan Semih , Dogan Ismail Cagri , Yildiz Mehmet , Barca Mehmet 
Published: November 2018

PurposeThis study looks to the answer of whether importers and exporters can develop relational trust and minimize the monitoring and control costs used to prevent opportunistic behavior in a trust relationship. Despite increasing scholarly interest in calculative and relational trust, the boundary conditions affecting the transformation of calculative trust into relational trust remain unaddressed. In response, this study aims to investigate the boundary conditions for the emergence of relational trust in inter-organizational relationships between Chinese exporters and Turkish importers.Design/methodology/approachData were collected from Turkish SMEs that import from China. To measure trust between parties, semi-structured interviews with top managers and/or decision-making company owners were conducted. Interview questions covered three categories: antecedents of trust, ways of developing trust and outcomes of trust.FindingsResults indicated that inter-organizational relationships between Chinese and Turkish firms lack relational-based trust. Most trade transactions between two parties are based on calculations of profit/loss, and Turkish firms use intermediary mechanisms to overcome lack of trust in this environment. The most important boundary conditions for the emergence of relational trust are behavioral uncertainty, the opportunistic behavior of Chinese suppliers and language and cultural barriers.Originality/valueThis study contributes to the existing literature by addressing the hitherto unaddressed question of what the boundary conditions are for the transformation of calculative trust into relational trust.
Using statistically designed experiment to optimize vacuum-assisted post-processing of binder jetted specimens
Authors: Movrin Dejan , Luzanin Ognjan , Guduric Vera 
Published: November 2018

Purpose
This paper aims to propose a vacuum-assisted post-processing method for use in binder jetted technology. The method is based on six key technological parameters and uses standard, commercially available consumables to achieve improvement in tensile strength, as well as the microstructure and porosity of the infiltrated matrix.

Design/methodology/approach
Six key technological parameters were systematically varied as factors on three levels, using design of experiment, i.e. definitive screening design. Surface response methodology was used to optimize the process and yield optimal tensile strength for the given range of input factors. Thus obtained, the optimized factor settings were used in a set of confirmation runs, where the result of optimization was experimentally confirmed. To confirm improvement in microstructure of the infiltrated matrix, SEM analysis was performed, while the reduction of porosity was analyzed using mercury porosimetry.

Findings
The obtained results indicate that, compared to its conventional counterpart, the proposed, optimized infiltration method yields improvement in tensile strength which is significant from both the statistical and engineering point of view, while reducing porosity by 3.5 times, using only standard consumables. Scanning electron microscopy examination of fractured specimens’ micrographs also revealed significant morphological differences between the conventional and proposed method of post-processing. This primarily reflects in higher surface area under hardened epoxy infiltrate, which contributes to increased load capacity of specimen cross-section.

Research limitations/implications
At the present stage of development, the most important limitation of the proposed method is the overall size of models which can be accommodated in standard vacuum impregnation units. Although, in this study, the infiltration method did not prove statistically significant, further investigation is required with models of complex geometry, various sizes and mass arrangements, where infiltration would be more challenging and could possibly result in different findings.

Practical implications
The most important practical implication of this study is the experimentally verified result of optimization, which showed that tensile strength and matrix microstructure can be significantly improved, using just standard consumables.

Social implications
Improved strength contributes to reduction of material consumption, which, in a longer run, can be beneficial for environment protection and sustainable development.

Originality/value
Based on literature review, there have been no previous investigations which studied the tensile strength of infiltrated specimens through design of experiment, which involved specimen preheating temperature, level and duration of vacuum treatment of infiltrate mixture and infiltrated specimens and infiltration method.
Characterization of a granulate-based strand deposition process in the FLM-method for definition of material-dependent process strategies
Authors: Schmidt Leander , Schricker Klaus , Bergmann Jean Pierre , Hussenöder Felix , Eiber Mathias 
Published: November 2018

Purpose
This study aims to characterize the suitability of a direct extrusion process in the fused layer manufacturing (FLM)-method under processing of granulated plastics.

Design/methodology/approach
In this paper, a granulate-based direct extrusion system in the FLM method is presented. This system is characterized with respect to the strand deposition mechanism and resulting component properties (geometrically and mechanically).

Findings
The extruder output could be identified as a linear relation between the applied extruder speed and the resulting mass flow. A developed model for the material and temperature-dependent strand deposition process was validated under experimental investigations. Further, it was possible to define process windows to realize desired strand widths and strand heights. In addition, analyses were conducted to determine the tensile strength transversely to the orientation of the layer plane.

Research limitations/implications
The extrusion system was characterized under the processing of materials ABS Magnum 8434 and PLA Ingeo 4043D. Due to the restricted choice of materials, further investigations are planned under an extension of the test materials. Furthermore, the degree of the geometric complexity of the test components should be increased to finally characterize the process.

Originality/value
By means of the characterization of the direct extrusion system, it is possible for users to classify the process and to use the process in specific application areas. In comparison to filament-based extrusion systems, significant advantages can be achieved by means of direct extrusion. These include, for example, the use of less expensive work materials (by factor >10), the use of existing test certificates and the advantage of higher mechanical properties. This makes it possible to meet modern product requirements and to produce competitive components.

Published: November 2018

PurposeThe risk control is an unavoidable step in the risk management process. It is materialized by concrete actions of risks reduction in order to decrease their likelihood and/or their severity and also to preserve the environment. The paper aims to discuss this issue.Design/methodology/approachThe main goal of the proposed methodology is to define the safety barriers (SB) that can be realized and their contribution to reduce major accidents scenarios that may occur in high-risk establishments.FindingsIn the proposed methodology, the authors present a combination of methods to prove the effectiveness of SB in an industrial installation.Practical implicationsThe proposed methodology is a valuable help to industrialists to secure their industrial activities and preserve the environment at the same time.Originality/valueThe retained methods are often used separately for audit purposes or risk assessments of high-risk industrial facilities. In this paper, three methods have been selected and articulated in an approach for a better evaluation of risk control level.

Published: November 2018

AbstractA comparative evaluation on the effect of carbon dioxide (CO2) on quality and shelf life of Atlantic salmon loins pasteurized with microwave and conventional technology was conducted. The experimental design allowed CO2 to enter the salmon muscle before (soluble gas stabilization [SGS] + vacuum) or after pasteurization (CO2 emitter + vacuum), whereas the control samples (vacuum only) were not presented for CO2. This setup resulted in six different groups; three heated with microwaves and three with conventional pasteurization. The core temperature of microwave samples was 58.8 ± 2.2 °C, whereas the surface temperature was equal to the oven temperature (62 °C) during conventional pasteurization and close to the core temperature during microwave pasteurization (57.6 ± 1.4 °C). Microwave‐heated samples showed higher microbial growth; decreased shelf life; and darker (lower L*‐value), more reddish (higher a*‐value), and yellowish (higher b*‐value) colors compared to conventional‐heated salmon. Lowest liquid loss (LL) was observed in salmon packaged with the CO2 emitter, whereas a SGS step prior to pasteurization did not affect the LL negatively as compared to samples packaged in vacuum only. Treatment with CO2, independent of the prestep using SGS or an emitter, resulted in increased shelf life. Protein denaturation, microbial growth, product color, product shelf life, and sensory properties of the salmon loin were significantly affected by the applied pasteurization method (microwave‐ or conventional pasteurization). However, the heat load was probably too high to detect differences resulting from the pretreatment using SGS or packaging with CO2 emitter.Practical ApplicationRecent developments with increased time pressure from both work and past time activities have led to a tremendous increase in the demand for convenient, tasty ready‐to‐use food options. Furthermore, contemporary trends for consumption of fresh or lightly processed seafood stress the need to develop processing methods that allow a fulfillment of these demands, while still offering a reasonable shelf life. Carbon dioxide in combination with either microwave or conventional pasteurization is innovative processing technology that can meet consumer's demand of such products.
