The effects of pressure, concentration and feed temperature using a high pressure membrane filtration test rig capable of handling nanofiltration and reverse osmosis separation was investigated. The experimental results indicated that the applied pressure across the membrane has a significant positive influence on the flux produced and increasing the pressure will rupture the membrane if excessive force or pressure is applied. The high concentrations of solutes/molecules inhibit the flow of fluid through the membrane consequently lower fluxes and improved separation is and subsequently all variables, including their interactions, examined was found to be significant.

Organic nitrogen plays a significant role in the fermentation performance and production of esters and higher alcohols. This study assessed the use of yeast protein hydrolysate (YPH) as a nitrogen source for grape must fermentation. In this study, we prepared an enzymatic protein hydrolysate using yeasts recovered from a previous fermentation of wine. Three treatments were performed. DAP supplementation was used as a control, while two YPH treatments were used. Low (LDH) and high degrees of hydrolysis (HDH), 3.5% and 10%, respectively, were chosen. Gas chromatography and principal component analysis indicated a significant positive influence of YPH-supplementations on the production of esters and higher alcohols. Significantly high concentrations of 3-methyl-1-penthanol, isoamyl alcohol, isobutanol, and 2-phenylethanol were observed. Significant odorant activity was obtained for 3-methyl-1-pentanol and ethyl-2-hexenoate. The use of YPH as nitrogen supplementation is justified as a recycling yeasts technique by the increase in volatile compounds.

In a rapidly changing business environment, the entrepreneurship of top management is essential for the survival and sustainable development of the enterprise. Building on the view of the strategic choice theory, this study identifies the relationship between entrepreneurship, market-oriented culture, and work engagement. Data were collected from 493 employees regularly working in small and medium-sized firms in South Korea. The results of this study indicate: (1) entrepreneurship (consisting of innovation, proactiveness, and risk-taking) has a significant positive influence on market-oriented culture, (2) entrepreneurship positively affects work engagement, (3) market-oriented culture has a significant positive effect on work engagement, (4) the effects of innovation and proactiveness on work engagement are significant, controlling for market-oriented culture, showing the partial mediating effect of market-oriented culture on work engagement, and (5) CEO trust moderates the relationship between risk-taking and work engagement. Theoretical and practical implications are suggested.

We conducted 3 laboratory experiments to determine how face consciousness influences consumption of counterfeit luxury goods, along with the moderating roles of usage occasion and brand prominence. The participants in the first study were 138 Chinese undergraduates who were allocated to a 2 × 2 design to evaluate their intention to purchase a counterfeit luxury item that would be used either in public or in private. In Studies 2 and 3, using two 2 × 2 designs we evaluated the purchase intention of the participants (132 and 136, respectively) in order to investigate the moderating role of brand prominence. The results showed that participants' face consciousness had a significant positive influence on intention to purchase counterfeit luxury goods. In addition, the products' usage occasion and brand prominence positively moderated the influence that face consciousness had on counterfeit luxury item purchase intention of our participant groups.

<p class="ArticleTitle">In recent years, the increasingly innovative and diverse mobile devices have significantly promoted the mobile device-based shopping. What factors influence this kind of shopping? Will consumers purchase things with mobile devices? These are two topics that need to be explored. Through the literature analysis and the empirical research, this study aims to analyze the quality of information, system, service and mobile devices on the mobile device-based shopping platform. Moreover, it studies the attitude of consumers towards mobile device-based shopping, their willingness to adopt the shopping method and the behavioral relationship model in the actual mobile device-based shopping as well as compares the groups of different frequencies of the Internet use in terms of the relationship model.</p>　　With the convenient sampling, this study made an investigation among some of those who had experienced shopping on such mobile devices as tablets or smart phones. The 765 retrieved valid copies of questionnaire were divided into three groups—“often”, “average” and “seldom” according to the frequency consumers undertook mobile device-based shopping and were then compared. The results showed that there were significant differences among the three groups in four relationship paths, including: 1) the information quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “average” group than in the other two; 2) the service quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “seldom” group than in the other two; 3) the preference for mobile device-based shopping has much significant positive influence on the behavior path of mobile device-based shopping in the “often” group. According to the research results, different groups have different behavior models. These results can serve as reference information in the decision-making of those who establish mobile device-based shopping platforms and manufacture mobile devices.

In recent times, an alternative synthesis pathway involving severe plastic deformation for Mg-based materials has been explored involving the generation of turnings according to a set of machining parameters and cold compaction into billets followed by hot extrusion. This is known as the turning induced deformation (TID) method and has shown potential to alter the properties of resulting Mg-based materials for the better, not to mention economic benefits arising from this processing method. This work summarizes exploratory efforts involving this method for synthesis of Mg-based materials. The TID method resulted in overall superior properties compared to conventional processing methods, while two distinct parameters (high depth of cut and low cutting speed) were found to have significant positive influence on the final material properties, and as such are considered to be suitable basis on which further exploratory work in this field may be conducted.
