“…If the CR value is less than or equal to 0.10, comparisons made by a decision-maker are considered acceptable. Larger values of CR indicate the lack of consistency in comparison matrix; hence, revision of the judgments of the decision-maker is required (Kursunoglu et al, 2017).…”

Purpose Following the emergence of Web 2.0 technologies, social commerce has been viewed as an inseparable part of today’s business environment. Social commerce is a recent version of e-commerce, which has rapidly become a new interesting field for both practitioners and academics. To improve social commerce success, managers should be aware of what encompasses social commerce quality, how consumers sense it and how it is assessed. Though, despite the importance of social commerce, designing of scales for measuring the social commerce quality has rarely been explored. Therefore, the purpose of this study is to develop a new scale for measuring the social commerce service quality comprehensively. Design/methodology/approach To obtain the research objective, in the first step, a comprehensive literature review along with focus group discussions was conducted to theoretically conceptualize service quality dimensions and measures. Then, for evaluating the proposed scale via social commerce customers, the survey method was used. Finally, the verified measures were weighted and ranked using fuzzy analytic hierarchy process. Findings The findings showed that social commerce service quality is a hierarchical and multidimensional construct consisting of six key dimensions including information quality, social interaction quality, design quality, functional quality, social trust/security and social support. Research limitations/implications The study results assist managers to improve the quality of social commerce services through increasing the awareness of customers’ perceptions and expectations concerning social service quality. They further help managers to understand systematically all dimensions of social commerce service quality, which may lead to reduce the risk of social commerce adaptation failure and consequently increase the customers’ satisfaction. Originality/value The role of service quality in acceptance and success of social commerce has been emphasized by many academics and practitioners. However, review of the previous literature shows that inadequate studies in this field have been conducted so far. The main contribution of this study is conceptualization and development of a validated scale for measuring the social commerce service quality. This scale provides a useful instrument for researchers who wish to measure the service quality of social commerce and for managers who want to improve the perceived quality of their services.

“…For this purpose, based on related research results, this paper aims to analyze the essential issues of curriculum setting of digital media major in the digital age, and explore relevant strategies and corresponding implementation paths for the target problems. Then, by integrating entropy method [12][13][14][15], AHP [16][17][18], and gray system theory [19], this paper gives a multi-attribute fuzzy analysis model for assessing the implementation effect of the professional courses of digital media major, in the hopes of providing useful help for the effective curriculum setting of digital media major in the digital age. The research content of this paper consists of 7 parts: the first part gives an overview analysis of related research concerning the setting of professional courses in the digital age, especially the professional courses of the digital media major; the second part discusses the essence of the curriculum setting of digital media major in the digital age; the third part analyzes problems existing in the curriculum setting of digital media major in the digital age; the fourth part discusses strategies for the curriculum setting of digital media major in the digital age; the fifth part gives the implementation paths, the sixth part analyzes the implementation effect, and the seventh part is the conclusion.…”

The professional courses of digital media major face several problems: too many influencing factors, unclear implementation strategy, and difficulty in evaluating the implementation effect. To solve these problems, this paper explores strategies and implementation paths for the professional courses of digital media major in the digital age. Firstly, the essential elements in curriculum setting were discussed, and the symptoms of the relevant problems were summarized; On this basis, the authors derived detailed strategies for the curriculum setting of digital media major. To ensure the effectiveness and reasonability of the professional courses of digital media major, an evaluation system and an evaluation model were constructed for judging the implementation effect of these courses. The research provides a strong support for the smooth implementation of the designed professional courses of digital media major, and a good reference for theorists and engineers in the relevant fields.

“…Lateritic oxide ores are considered as the main resources of nickel. Recovery of nickel from laterite ores is becoming increasingly important since their availability is 86% of the nickel reserves on the Earth [1][2][3][4][5][6][7]. Extraction of nickel from ores with high Ni/Fe ratio and low moisture content is carried out by pyrometallurgical processes.…”

Corresponding to the technological developments, production and consumption of nickel have increased greatly over time due to its unique mechanical and chemical properties. Therefore, the production of nickel will always keep its importance. The availability of laterite ores, which are oxide type ores, is 86% of the nickel reserves on the Earth, and the processes used in the production of nickel from sulfide type ores have negative environmental effects. Therefore, recovery of nickel from lateritic ores has become increasingly important in recent years. In this study, the aim was to determine the optimum parameters of nickel and cobalt production from limonite type lateritic nickel ores, which were taken from Manisa Caldag region of Turkey, using atmospheric pressure sulfuric acid leaching and pug-roast-leach process. When the results obtained in these processes were compared, it was found that the Ni leaching efficiency is nearly 8% higher and iron leaching efficiency (contamination) is nearly 4% lower in the pug-roast-leach process. Furthermore, the pug-roast-leach process was completed in 33% lower time compared to the atmospheric pressure sulfuric acid leaching process.
