Charting the path to consumer satisfaction: An innovative investigation into fresh e-commerce through text mining and spatiotemporal analysis
Full text linkThe rapid expansion of fresh food e-commerce introduces significant challenges in logistics service quality due to the perishability of products. However, the effects of these challenges on customer satisfaction, particularly across different regions and seasons, have been insufficiently explored. This study addresses this gap by analyzing Jingdong (JD)’s e-commerce reviews using latent dirichlet allocation (LDA) topic models to extract dimensions of logistics service quality, combined with sentiment analysis to evaluate both service quality and customer satisfaction. The research investigates how logistics service quality influences satisfaction, accounting for spatial and temporal variations. Key findings reveal that logistics attributes such as quality assurance, reliability, and convenience play a crucial role in shaping customer satisfaction, with their relative importance differing by region and season. For example, convenience is more critical in remote areas, whereas affluent regions place greater emphasis on empathy. Additionally, higher temperatures amplify the impact of logistics attributes. Repeat customers tend to demand higher service quality compared to first-time buyers. These insights provide actionable recommendations for e-commerce firms seeking to optimize logistics services and enhance their competitiveness
Identification of consumers willing to buy green products – A case study in the Czech Republic
Full text linkGreen products are one way to protect the environment and eliminate the negative impact of human activity on the environment. However, the expansion of the sale of these products faces many challenges. One of the most significant obstacles is often cited as higher prices. The aim of this paper was to identify consumers willing to buy green products. The primary factors analysed were the social background of consumers, price and the premium for green products. Secondary data in the form of other research on the issue was used to meet the objective. The theoretical aspect of green product purchasing behaviour was supplemented with information from the processing of primary data from a questionnaire survey. The target group was the working-age population with at least a secondary education in the northwest of the Czech Republic. The survey was conducted between May and September 2023 on a sample of 267 respondents. A factor analysis was used in the data analysis to identify the relationships between the factors under study and to reduce the dimensionality of the data, as was segmentation using cluster analysis and classification using decision trees. The results provide information on the green purchasing behaviour of consumers in the study region. Two segments of marketing interest for green product purchasing were identified. One is the segment of ordinary consumers, mostly well-off women with children, who are willing to pay more for green products than other groups of people. The other interesting segment was mostly single women, influenced by opinions on their environment, who do not buy green products regularly and are willing to pay extra for green products, but not a significant amount. The findings of the study may provide useful information for marketers when planning and implementing activities related to green products
Soft total quality management and employee performance: The resonant effect of leader narcissism
Full text linkStemming from the purpose of exploring the changes made by narcissism in the context of hospitality enterprises with total quality management (TQM) implementation, this study proposes a multi-level analytical framework taking into account the moderating effect of leader narcissism on the relationship between soft TQM practices and employee performance on the basis of the abilities, motivations, opportunities framework and the social information processing theory. The analysis of survey data from 1,155 employees from mid- to high-end hotels in two famous tourist cities in Vietnam allowed us to empirically test the relationship between these constructs. The findings showed that communication, teamwork, training and development create significant improvements inemployee performances. More importantly, themoderating role for leader narcissism is confirmed in the relationship between training and development and employee performance. Therefore, the study highlighted theoretical implications related to a holistic approach to narcissism – the controversial psychological characteristics of leaders in the workplace. In addition, a number of managerial implications have been provided for hotel managers in enhancing the effectiveness of TQM implementation for improved performance through promoting the role of narcissistic leaders
The link between corporate strategy and innovation in developing countries: The post-crisis trends and challenges
Full text linkThis study aims to identify interrelationships between corporate strategy and innovation in developing countries in the post-COVID-19 context. The purpose of the study is to form a model that would allow to consider and process the impact of the innovational operations to the choice of the corporate strategy and its development within the operational domains of the developing countries, which ultimately can be able to meet the challenges in their economic growth and therefore contribute to the better outcomes of the post-crisis situations. The research hypotheses are that the post-crisis innovation activities do not depend on (H1) the ownership of the firm, (H2) its scale of operation, (H3) and industry but on (H4) the firm’s life cycle stage, and (H5) the strategy complexity level. Here, the survey of 424 random respondents from 424 Chinese firms provides evidence that refutes the first and third hypotheses (H1 and H3) while confirming other hypotheses (H2, H4 and H5). In addition, most respondents disagreed with the statement that “innovation is of secondary importance during the post-crisis period,” which suggests that innovation is a prerequisite for sustainable development. In addition to the previous research connected with the issues of corporate strategy and innovation, the present study has come up with the original hypotheses providing refutations and a new vision to the problem. The research findings present an extension to the understanding of corporate strategy and innovation during the post-crisis period, hence leading to the emergence of the up-to-date instruments able to solve the issues of the real economy after the COVID-19 crisis. The questionnaire, chosen as the research method, consisted of 18 2-section items, including a 7-item respondent profile and a 9-item analytical section. The respondent profile’s questions were: year of establishment of the firm (Q1), form of ownership (Q2), respondent’s position at the enterprise (Q3), sector in which the firm operates (Q4), firm size (Q5), profitability dynamics (Q6) and employment dynamics (Q7). The analytical section asked about the corporate strategies and innovation interactions. Q11 and Q12 resulted in 19.3% and 23.2% higher positive choice by private and limited liability firms, agricultural firms’ results were 27.3% below the average, start-ups and new firms’ activities demonstrated 14.7% more intensive innovative steps. Diversification is linked to the increased involvement into innovations, while the decreased level of innovation activity is linked to merger and acquisition practices. Ultimately, the first and second hypotheses (H1 and H3) were empirically proved to be false, and the remaining hypotheses (H2, H4 and H5) were confirmed. The present findings can be used to inform corporate strategy decisions in the real sector of the economy after the COVID-19 pandemic
INVESTIGATION OF THE EFFECT OF SOFTENERS ON COTTON KNITTED FABRIC STIFFNESS
Full text linkTextile comfort of the fabrics is becoming very popular and soft touch is one of the prominent features. The main desired properties of cellulosic knits are their pleasant appearance, softness, absorbency, breathability, texture and comfort, which make them ideal for use in casual wear, sportswear, underwear, etc. Improving the performance and properties of cellulosic knits such as dimensional stability, smoothness, drapability, etc. through functional finishes is becoming necessary to cope with the demands of consumers and garment manufacturers. In this novel study 2 types of knitted structures (single jersey and pique) made of 100% cotton were used. Three different softening chemicals (macro silicone, micro silicone and seam facilitator) were used and acetic acid were used as a binding agent. According to the results, it was determined that macro silicone softener in single jersey knitted fabric and seam facilitator softener in pique knitted fabric gave more effective results in terms of hand feeling properties

In this study, the types of textiles used in the facade and roofing systems of stadium facilities in Türkiye have been examined. The advantageous properties of textiles employed in stadium structures characterized by substantial roof and facade openings at the structural scale have been critically analyzed in relation to other conventional building materials. The technical textile material summary demonstrates the tremendous diversity of today's membrane materials using stadium facilities in Turkey
PROPERTIES OF WOOL FIBERS REINFORCED COMPOSITES
Full text linkNatural fiber-reinforced composites (NFRCs) have gained significant attention for their array of advantages, including biodegradability, low density, and cost-effectiveness compared to synthetic fiber-reinforced composites. The surge in interest is driven by a global shift towards sustainability and eco-conscious practices across various industries. Consequently, there has been a significant increase in exploration and innovation within the realm of natural fiber composites, reflecting a collective effort towards more environmentally friendly material solutions. Industries such as automotive, construction, aviation, and aerospace are increasingly exploring the use of natural fiber composites. However, the flammability of natural fiber-reinforced composites is a major challenge that needs to be addressed. Wool fiber, known for its natural flame-retardant and self-extinguishing properties, has been widely used in the textile industry to produce apparel, but its use in composite production has been limited. This study explores the feasibility of using wool fibers for composite reinforcement, primarily for applications where fire resistance is required. In this work, wool woven fabric and unidirectional (UD) wool roving were used as preforms, and a bio-based resin was applied through resin infusion techniques to produce the composites. The prepared composite samples were subjected to tensile, three-point bending, thermal insulation, and fire-resistance experimental investigations. The results obtained from the experimental investigations indicate that wool fiber has promising potential as a reinforcement material in composite applications mostly where fire resistance is critical
