The purpose of this paper is to investigate the potential food and industrial values of a tropical and underutilized indigenous plant.

Specimens of a dry‐milled plant, namely: Zizyphus spina‐christi, were subjected to chemical analysis to determine their proximate, mineral, sugar, and amino acid compositions using standard procedures.

The fruit pulp was found to be a good source of energy, carbohydrates and rich in Mg, Ca, Fe and Zn, whereas the seeds are rich in crude fiber. Essential amino acids are 32.96 percent in fruit pulp and 25.22 percent in seeds, whereas non‐essential amino acids are 61.25 percent in fruit pulp and 73 percent in seeds.

The nutritional composition of the plant materials suggests that they may find use in food formulation operations and as industrial raw materials.

Using destination brand experience as a conceptual lens and data evidence from international visitors to Egypt, the purpose of this study is to examine the relative impact of the various dimensions of local food experience on tourist overall food satisfaction and destination revisit intention.

Data from a convenience sample of international visitors to Cairo, Egypt, (N = 302) was quantitatively analyzed using the structural equation modeling approach to test the relationships among constructs.

Empirical results reveal that three components of destination food experiences – sensory, affective and behavioral – effectively explain tourists’ food satisfaction and destination revisit intention, while intellectual food experience was reported to only influence destination revisit intention. Interestingly, the effect of food experience satisfaction on destination revisit intention was not significant.

This study identifies local food experience aspects that require to be managed at a strategic level and provides guidelines on how these aspects can be effectively managed.

This study is the first empirical application of a multidimensional experience model to the context of tourists’ local food experience; it identifies the multifaceted characteristics of local food experience that deserve scholars’ and marketers’ attention.

This study aims to evaluate the interface of the mobile Centralized Doctor Appointment System (CDAS), the largest mobile e-government health application developed in Turkey to allow citizens to make medical appointments at public hospitals.

A total of 40 information systems engineers took part in the study. The evaluation process was mainly based on Nielsen’s heuristics. The data obtained in the evaluation process were enriched using system usability scale to conduct a more detailed analysis.

Based on the findings, problems related to the usability of the evaluated mobile health application were identified. The most violated heuristic items were found to be “error prevention” and “user control and freedom”, whereas the least violated heuristic item was “consistency and standards”. The participants generally categorized the usability problems they identified as “minor” or “major” according to their severity.

As a developing country, Turkey has made considerable investment in mobile e-government applications in recent years. It is equally important that mobile e-government services provided by public institutions have features that make these applications effective, efficient and satisfying for citizens. Therefore, the usability of mobile health applications in government services needs to be researched to improve their effectiveness and guide authorities, practitioners and designers.

Najib Mahfuz is the first Arab‐language author to win the Nobel Prize in literature. Born in 1911 the son of a middle‐class Jamaliyah merchant, he became the most popular novelist in Egypt and the Arab countries.

This study aims to dissect firm knowledge into two main types: internal firm knowledge (knowledge workers) and external firm knowledge (relational knowledge with other firms). This study aims to investigate how each type affects the productivity of the firms. This study also examines how this effect differs among Egyptian firms in the agriculture, manufacturing and service sectors.

The authors use firm-level data in Egypt on the sectoral level. The properties of instrumental variables regression using two-stage least-squares estimation are adopted to overcome endogeneity and omitted variable bias in the empirical estimations.

The study’s findings reveal that the effects of internal and external knowledge on the firm productivity are sector-specific; knowledge-workers and relational knowledge are two times more effective for agriculture than manufacturing and service firms; external knowledge plays a vital role in increasing productivity relative to internal knowledge for the manufacturing sector; finally, internal and external knowledge has the same effect on the service firms.

This research adds to the body knowledge-based theory of the firm by examining the effects of internal and external knowledge on the firms’ productivity. In particular, the paper differentiates this effect across three sectors: agriculture, manufacturing and services. This paper also suggests a novel empirical methodology to address endogeneity and omitted variable bias in this literature of firm knowledge and productivity.
