The Influence of the Application of Agile Practices in Software Quality Based on ISO/IEC 25010 Standard

Agile practices are activities or procedures that are applied during the software development process in order to improve its quality and productivity. The objective of this study is to determine the influence of agile practices on software quality. For this purpose, a model composed of 4 groups of agile practices and 8 quality characteristics according to the ISO/IEC 25010 standard has here been proposed. The results of 146 questionnaires addressed to people involved in the software development process show that the application of agile engineering and project management practices have a significant positive influence on the quality attribute functionality. On the other hand, project management practices have a low impact on the quality characteristics of compatibility, portability, security, and usability.

Recycling and Conversion of Yeasts into Organic Nitrogen Sources for Wine Fermentation: Effects on Molecular and Sensory Attributes

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.

Impact of neuroprotective therapy on cognition and oxidative stress in the early stages of Parkinson’s disease

The aim of this study was to investigate the clinical and biochemical efficiency of citicoline in cognitive improvement and changes of glutathione peroxidase (GPx) blood plasma levels in patients at early stages of Parkinson’s disease (PD). Materials and methods. We recruited 42 patients at I–II Hoehn and Yahr PD stages and 20 controls. The Montreal Cognitive Assessment test (MoCA) was used to assess several cognitive domains in PD patients (before citicoline treatment, after intravenous therapy and after pills therapy) and controls (once). Plasma was collected once in controls and twice in PD patients (on the first and the last days of observation). Citicoline was administrated to 23 of 42 PD patients in addition to basic antiparkinsonian therapy intravenously during 10 days and with pills during next 30 days. The rest 19 of 42 PD patients had been taking basic antiparkinsonian treatment only (comparison group). Results. We observed significant improvement of MoCA scores in PD patients with citicoline course (PD-Cs) in each check day. But in spite of such an improvement in PD patients, who were left on the basic antiparkinsonian treatment (PD-Bs), on the 10th day of observation, patients of this group did not keep it to the last day of the research (P < 0.001). After the treatment the GPx level in plasma of PD-Cs was significantly higher than in PD-Bs (P < 0.001). Furthermore, the activity of GPx plasma level after citicoline course was significantly higher than before additional neuroprotective therapy, which wasn’t observed in PD patients on basic treatment only. Conclusion. The cognition of PD patients (according to MoCA scores) at the early stages of the disease was significantly improved after citicoline treatment. Citicoline treatment had significant positive influence on the increasing antioxidant GPx plasma activity in PD patients at the early stages of the disease.

Assessment of Consumers Acceptance of E-Commerce to Purchase Geographical Indication Based Crop Using Technology Acceptance Model (TAM)

Diffusion of Information and Communication Technology (ICT) in every aspect of life has made the applications of e-commerce a fundamental part of marketing. Hence using e-commerce to market Geographical Indication (GI) based crops is quite essential for the survival of the growers associated with such crops. Due to this significance, it is critical to assess consumers acceptance of e-commerce to purchase geographical indication-based crop. The study uses Technology Acceptance Model (TAM) to validate consumers’ willingness of using e-commerce to purchase GI crops with specific reference to Udupi jasmine. To analyse the relationships between TAM variables, Structural Equation Modelling (SEM) technique was adopted. The analysis suggests that behavioural intentions of consumers will influence them into actual e-commerce use. Behavioural intention exerts a significant positive influence on the actual e-commerce use suggests that, if provided with an e-commerce application to purchase the product online, consumers are likely to accept and use it.

Influence of Fishery Cooperative Support on Safety Factor Input Behavior of Aquaculturists: The Intermediary Role of Order Fishery and Product Certification

This paper used 586 survey data of aquaculturists in the Shandong and Zhejiang provinces of China and built two intermediary effect models by incorporating fishery cooperative support, order fisheries participation, product quality certification, and safety factor input behavior into the same theoretical analysis framework in order to verify the direct influence of fishery cooperative support on safety factor input behavior of aquaculturists, as well as the intermediary effect of order fisheries participation and product quality certification in the relationship between fishery cooperative support and safety factor input behavior of aquaculturists. The research concluded that fishery cooperative support has a significant positive influence on safety factor input behavior. Participation in order fisheries and product quality certification have a partial intermediary effect in the relationship between fishery cooperative support and safety factor input behavior of aquaculturists; their intermediary effect accounts for 10.3% and 33.7% of the total effect. The research conclusions can provide reference and suggestions for China’s fisheries to better carry out green aquaculture.

The Promise of Turning Induced Deformation Process for Synthesizing Magnesium Based Materials with Superior Mechanical Response

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.

The sample is 263 e-commerce users in Surabaya, Malang, and Kediri who have e-commerce account and know about Sensatia Botanicals. The Data was analyzed using PLS (Partial Least Square) in SmartPLS 3.0. The results of the analysis indicate that performance expectancy, facilitating conditions, social influence, habit, perceived playfulness and price value have a significant positive influence on the behavior intention to use e-commerce, and that effort expectancy and hedonic motivation do not have any significant positive influence. Gender difference in this study can increase the intention of individuals to use e-commerce on the price value factors, while age and income difference in this study neither increase nor decrease the intention of individuals to use e-commerce to purchase the products of Sensatia Botanicals.

Instagram influencer marketing: Perceived social media marketing activities and online impulse buying

The main objective of this research is to investigate the impact of social media marketing activities — restricted only to Instagram influencers — on online impulse buying through the mediating effect of source credibility (attractiveness, expertise, and trustworthiness), predicated on Stimulus-Organism-Response (S-O-R) theory. The hypothesised relationships were examined using cross-sectional data obtained from 273 Instagram users. Partial least squares structural equation modelling (PLS-SEM) using the SMART-PLS software was employed as the primary data analysis method. The results revealed that the perceived social media marketing activities of Instagram influencers have a significant positive influence on the perceptions of followers pertaining to all three dimensions of source credibility (attractiveness, expertise, and trustworthiness). In turn, only attractiveness and trustworthiness were found to have a significant positive influence on online impulse buying. Moreover, this study revealed that it was the perceived attractiveness and trustworthiness of Instagram influencers that were the influential mediating factors in the relationship between perceived social media marketing activities and online impulse buying. There is a dearth of studies that have been conducted on the examination of the mechanism through which Instagram influencers’ social media marketing activities influence online impulse buying. This study is significant as it provides new insights into the importance of Instagram influencers social media marketing activities in affecting followers’ online impulse buying through source credibility.
