This study examines the role of the emotional experience of mobile food shopping in stimulating perceived values and continued intentions under the moderating role of consumer expertise.

We gathered data from 632 Saudi mobile food shoppers through a web survey and analysed it using structural equation modelling.

The results showed that emotions (i.e. pleasure, arousal and dominance) significantly affect immersion in the experience of shopping via mobile food applications, which generates significant functional and emotional values and ultimately influences continued intentions. However, they do not have a significant effect on social value. Consumer expertise significantly moderates only the relationships between functional and emotional values with immersion and between immersion and continued intention.

Formulating a marketing strategy based on the emotional dimension is a potentially powerful way to enhance the attractiveness of mobile food applications. Nevertheless, segmenting the market based on consumer expertise is crucial for customising offers.

This study contributes to the literature by integrating pleasure-arousal-dominance theory with the theory of customer value to examine the role of the emotional dimension in the development of perceived values and continued intention to use mobile food ordering applications. Additionally, this study adds to the literature by examining the moderating role of user expertise in these relationships.

This paper aims to study the influence of organic food perceived values (utilitarian vs hedonic) on consumer willingness to buy and willingness to pay in a developing country.

This paper utilized a survey of 467 Tunisian consumers of organic olive oil. Data were analyzed using structural equation modeling (SEM) to test the reliability and validities of constructs, as wells as model fit and the structural model.

The findings indicate that both utilitarian and hedonic values have significant influence on consumer willingness to buy and to pay for organic olive oil. The hedonic value has a stronger influence on willingness to buy while the utilitarian value has a stronger influence on willingness to pay.

This study contributes to knowledge regarding the relationships between organic food perceived value and consumer willingness to buy and to pay. Findings provide clear ways for practitioners to communicate the perceived values of their organic foods in order to increase their consumption.

This paper is one of the rare studies that focuses on willingness to buy and to pay for organic food in a developing country. In addition, it is a first attempt to test the consumer perceived values of organic olive oil in the context of one of the biggest producer countries of this type of food.

Purpose: This study aims to investigate the effect of culture on innovation within the workplace. Special attention has been paid to Middle East and North Africa (MENA) culture features and their impact on employees’ adaptation to the innovation within their organizations.

Approach/methodology: To achieve this objective, a theoretical study has been carried out. Given its popularity in culture-related research, the Hofstede model has been used to understand the specificities of MENA region culture. An extensive literature review has been employed to investigate the relationship between culture and innovation in the workplace.

Findings: Based on the relevant literature, it can be said that the country’s culture has a considerable impact on how the employees adapt to the changes within the workplace. Some issues of Arab culture that managers should be aware of and suitable solutions have been underlined to improve the adoption of innovation within the organizations in Arab countries.

Research implications: This study contributes to knowledge regarding the association between innovation and culture within the workplace in the MENA region. Findings provide straightforward ways for managers to improve the adaptation of their employees to the growing innovation required by the global market.

Originality/value: This study is among the earliest to focus on the association between innovation and culture within the MENA region. In addition, it is among the rare studies, which explore the main issues of Arab culture that make the adaptation to innovation a complex phenomenon that requires further efforts from managers for successful innovation performance. The limitations, as well as the future research pathways, have been mentioned at the end of this study.

The literature reveals there is a limited knowledge regarding the extraction of long natural fibers, in particular those extracted from leaves. This investigation aims to present the extraction process and the characterization of long natural cellulose fibers from doum palm leaves (Hyphaene thebaica L.), with properties suitable for polymeric composite materials and textile applications.

The resulting H. thebaica L. fibers were identified using Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The physical properties of the extracted fibers were measured to estimate the reliability of extraction conditions. Mechanical properties were evaluated to determine ultimate strength, Young’s modulus and strain-at-failure of the fibers of the doum leaves.

The following properties of the doum palm are listed in this paper: physical properties of doum palm fibers (H. thebaica L.), TGA, XRD of doum palm fibers, tensile properties of doum palm fibers and surface morphology of doum palm fibers.

Like synthetic fibers, the inclusion of short or long natural fibers into the polymer matrix can increase tensile, flexural and compressive strengths of these matrixes. Compared to the short-length natural fibers, longer-length fibers provide better reinforcements and therefore accord higher performances to the composites. Long fibers can also provide exceptional opportunities to develop a new class of advanced lightweight composites and have the potential to rival glass fiber in the manufacture of composite materials, using matrix materials, such as polypropylene, epoxy and phenolic resins.

The following values are presented in this paper: density of doum palm fibers = 1.14-1.40 g/cm², linear density (Tex) = 33.10 ±11.5, equivalent diameter (µm) = 178.72 ± 41.7, diameter (µm) = 137.02-220.42, tensile strength (MPa) = 124.84-448.10, Young’s modulus (GPa) = 8.06-19.59, strain-at-failure (%) = 0.81-2.86.
