The purpose of this paper is to envision the alternative futures of the design and manufacturing industry using an integrated foresight method based on scenario planning. Also, the authors aim at developing robust strategies for an enterprise that aims to be placed as a leading high-tech international design and manufacturing company in 2035.

The proposed approach is created by integrating several foresight methods such as Delphi, scenario planning, MICMAC and cross-impact analysis.

Automation and sustainable development are found as the fundamental driving forces in the design and manufacturing industry. Four scenarios based on these driving forces and expert knowledge are created: innovation adaptation, forced automation (business-as-usual), sustainable era and automationless scenarios. For the developed scenarios, a set of strategies are proposed by asking experts about the strategies which can be taken to make the enterprise competitive in all developed scenarios in 2035. The main macro-level outcome is that economic and technological drivers will be the most important factors for design and manufacturing, followed by environmental and social factors.

The proposed method uses the strengths of traditional scenario planning but overcomes its weaknesses by suggesting a systematic process for scenario building and easy application.

To quantitatively measure the subtle and general symptoms of autism spectrum disorder (ASD), one of the instruments that have been designed and used is the social responsiveness scale (SRS). The purpose of this study is to translate the second edition of the SRS into Persian and to examine its psychometric properties in school and preschool children with ASD.

The present study is a methodological study of the psychometric type; the study population consisted of school and preschool children from 3 to 12 years of age with ASD and an intelligence quotient of approximately 70. In total, 10 professors and occupational therapists with research and clinical experience in the field of children, were selected for the translation and content validation stages by expert sampling. To determine the validity of the instrument, the content validity index (CVI) and the content validity ratio (CVR) were used; in addition, to determine the reliability, the internal consistency determination method with Cronbach’s alpha number report and inter-rater reliability method within-class correlation coefficient report were used.

The calculated CVI and CVR of the instrument for all instrument items were 0.82 and 0.86, respectively. The intra-class correlation coefficient performed by different raters was 0.80 and Cronbach’s alpha for all items was 0.93.

The reliability and validity of the Persian version of the social responsiveness scale-second edition are appropriate and acceptable so that this instrument can be used to assess the social performance skills of 3–12-years-old children with ASD for research and clinical study.

This study aims at introducing a claim management model based on building information modeling (BIM) for claims that can be visualized in BIM models.

Based on the results of a questionnaire survey, 10 claims were identified as claims that can be visualized in BIM models (named hard claims in this study). Then, a BIM-based claim management model was developed and used in a case study.

A BIM-based claim management model is represented. The claim management process through this model consists of four steps: (1) extracting project information, identifying conditions prone to claim and storing them into a relational database, (2) automatically connecting the database to building information model, (3) simulation of the claims in building information model and (4) final calculations and report.

The proposed model can provide benefits to parties involved in a claim, such as early identification of potential claims, large space for data storage, facilitated claim management processes, information consistency and improved collaboration.

There are a few studies on providing solutions to claim management based on BIM process. Hence, the original contribution of this paper is the attempt to set a link between BIM and claim management processes.

In the shipping industry, both sales and purchases of second-hand ships and freight transport services are prevalently tailormade and traded with intense bilateral negotiations. Price bargaining is the key step of this negotiation process and plays a crucial role in determining mutually agreed prices. Despite its cruciality and applicability, the price bargaining has yet received due conceptual and/or theoretical attention in the shipping literature. This paper attempts to conceptually examine the role of bargaining in shipping transaction prices and subsequently puts forward directions for future research. In doing so, the paper focuses on two types of transactions taking place in shipping markets: asset market trading of second-hand vessels and service market trading shipping freights.

The paper begins with a systematic literature review of price bargaining in the field of economics and management disciplines from a game-theoretic perspective. This approach does logically lead to the establishment of a conceptual framework for price bargaining in shipping sub-markets as a step toward having taken into consideration a variety of heterogeneities commonly present in trading activities and market dynamics.

A set of research areas has been consequently identified where price bargaining and mechanisms for the shipping freight and asset markets could be further explored and analyzed in a way to make better pricing decisions under a more tangible framework.

One of the critical challenges when using bargaining mechanisms to make a decision on pricing shipping services and assets is how to operationalize the study for empirical investigation as some of the factors are internal information of the players and are not adequately revealed to externals: that is, an imperfect information sharing case. The current study aims, however, not to conduct an empirical analysis but to initiate a conversation among maritime economists by bringing their attention to this not-yet fully explored and potentially impactful field of research and by asking them to treat bargaining from a perspective for pricing shipping assets and services. It is claimed that, by doing so, one could better understand price differences between individual contracts.

This study would be considered the first of its kind to provide a detailed survey of the bargaining theory and models from a game theoretical perspective as a theoretical lens to understand its importance and relevance in pricing shipping assets and services. It also provides a simplified operational case on utilizing bargaining in practically pricing freight services.

The purpose of this paper is to characterize and identify the existing studies on the relationship between technological media and development

The authors conducted a systematic mapping study to identify and analyze the related literature. The authors identified 196 primary studies, dated from 2000 to 2017 and categorized them with respect to research focus, types of research and research method.

A total of 97 studies were identified and mapped, synthesizing the available evidence on the relationship between technological media and development. “Social development” with 54 articles and “communication” with 34 articles were the dominant research focus. Regarding the research type, “Solution proposal” is the most frequently employed research type. “Case study,” “discussion paper” and “interview,” respectively were the most used research methods. However, “SNA,” “focus group” and “time series” were used less often. “Solution proposal” was the most common research type between 2015 and 2017, and after that “philosophical paper” was the dominant research paper type. Further, the number of publications has increased between 2006 and 2017.

This mapping study is the first systematic exploration of the state-of-art on technological media-development nexus. The existing body of knowledge is limited to a few high quality studies.

This paper inspects in detail the seasonality (deterministic) in container freight rates, and compares seasonality patterns in different freight rate indices. A deterministic seasonality unit root test is performed to achieve set objectives. This study concludes that all the indices (tested in this paper) exhibit significant deterministic seasonality. For January and August, there is no seasonal effect observed in all five series. At the same time, all the indices except Exports from Europe Rate Index (EEI) exhibit significant seasonal patterns in February, September, and December. All five indices exhibit significant seasonality during May, and the coefficient sign shows a drop in the freight rates. During March, October, and November; it is observed that only EEI exhibit significant seasonal patterns. The results could be beneficial for carriers and agents who are involved in the containerised freight transport business. Also, shippers could get a clear idea about the freight rates' nature across various trade routes.

Food fraud has vexed the food industry throughout history. Today, it is still a present and multidimensional problem affecting all parts of the food industry. Food fraud encompasses adulteration, counterfeit, diversion of products outside of intended markets, over-run, simulation, tampering, theft, misrepresentation or mislabelling, malicious poisoning, bioterrorism or sabotage. It is difficult to detect and trace the source of unintentional contamination and related food safety concerns and even more difficult to detect instances of product fraud. The most common product categories that are associated with food fraud are olive oil, milk and milk-based products, fish and seafood, wine, tea, honey and organic foods. On the other hand, knowledge on what influences the occurrence of fraud in food supply chain is limited. The main research aim in this chapter is to determine key factors which influence the occurrence of food fraud within the organic supply chain, and how these factors differ between various organic marketing channel members. We focus on the application of qualitative methods for detecting key food fraud aspects including broad practical areas, such as opportunities and motivations to commit fraud, as well as the presence or lack of suitable food fraud control measures. These three key aspects are assessed to identify the perceived fraud vulnerability of the organic supply chain. The research is conducted with special attention to the context of the transition economies, since these markets require a new, comprehensive strategic approach to preventing and detecting food fraud and adulteration. The entire analysis is conducted on the Serbian market.

The number of MSMEs is very influential in economic growth, especially in developing countries. What is of concern to developing countries, although the number of MSMEs is increasing every year, they cannot develop in an increasingly competitive business environment. In this case, good business performance is needed to survive in this intense competition. This study tries to make a performance model of small-scale enterprises by finding out the effect of entrepreneurial competency variables and moderated by the variable competitive sphere and capability of organization. We use the partial least squares to confirm the theory and get answers about the influence between variables. Respondents of this study were 100 MSME owners in Bandung, Indonesia. The study's findings revealed that entrepreneurial competence had a significant influence both directly and indirectly on small firm performance. The variable of entrepreneurial competence provides the most powerful influence on the competitive sphere than organizational capability's moderating variable. Although the moderating variable of organizational capability is not as strong as the competitive sphere in influencing firm performance, it has a strong predictor (quality and flexibility).

One way of overcoming logistics barriers (poor transportation, handling and storage properties) towards increased utilisation of biomass is to introduce a pre‐treatment process such as torrefaction early in the biomass‐to‐energy supply chain. Torrefaction offers a range of potentially beneficial logistics properties but the actual benefits depend upon how the supply chain is configured to address various elements of customer demand. Hence, the aim of this paper is to develop a framework for torrefaction configuration in a supply chain perspective for different types of customers.

Sophisticated pre‐treatment processes are yet to reach the commercialisation phase. Identification of possible supply chain configurations is in this paper done through a conceptual approach by bringing together knowledge from related research fields such as unrefined forest fuel, pellets and coal logistics with prescriptions for configuration derived from the subject area of supply chain management (SCM).

A framework that explicates different elements of supply and demand of torrefaction is proposed, and exemplified by three distinct supply chains. Depending on demand, torrefaction serves different purposes, bridging gaps in place, time, quality and ownership. Furthermore, different supply chain configurations will pose different requirements on torrefaction in terms of producing different product quality, durability, energy density and hydrophobicity of the pellets.

The proposed framework entails a set of propositions, but requires further development through empirical studies using complementary research methods such as interviews or surveys and quantification through techno‐economical or optimisation from a supply chain perspective.

This paper provides a framework that can inform decisions makers in biomass‐to‐energy supply chains, in particular at torrefaction plants, on upstream and downstream implications of their decisions.

The findings have implications for biomass‐to‐energy supply chains in general, and in particular, the paper provides a supply chain perspective of pre‐treatment processes, where previous research has focused primarily on technical aspects of torrefaction.

The purpose of this paper is to investigate the influence of sprue distributions on the flow field and temperature field of the cladding casting process and verify the simulation results by experiments.

A steady-state mathematic model for the coupling of fluid flow, heat transfer and solidification to describe the process of cladding casting was present. The effect of sprue distributions on melt flow and temperature field was discussed. Based on the numerical simulation results, the cladding billet was prepared successfully. Moreover, the model has been verified against by temperature measurements during the cladding casting process.

There is a good agreement between the measured and calculated results. The homogeneity of melt flow determines the formability of cladding billets and circular temperature difference affects the bonding of the two alloys. The AA4045/AA3003 cladding billet with no defects in size of f140/f110 mm was fabricated successfully. The alloy elements diffused across the interface and formed diffusion layer with a thickness of 15 µm. The interface bonding strength is higher than the tensile strength of AA3003, indicating the metallurgical bonding between two alloys.

The casting parameters are limited to the aluminum alloy cladding billet in size of f140/f110 mm in this paper.

There are few reports of cladding billet, which are used to prepare condense pipes of automotive engines. The effect of distribution schemes on the cladding casting process is rarely studied.
