Sex and age estimation is important, particularly when information about the deceased is unavailable. There are limited radiological studies investigating side, sex and age differences in normal ankle morphometric parameters. The authors’ goal was to evaluate different ankle joint morphometric measurements and document variations among Egyptians.

A prospective study was conducted throughout 23 months on 203 (100 males and 103 females) adult Egyptians, aged between 20-69 years old, who were referred for a plain x-ray of bilateral normal ankle joints.

Ankle parameters showed no statistical difference between both sides, except for tarsal width (TaW) which was significantly higher on right than left side (26.92 ± 2.66 vs 26.18 ± 2.65 mm). Males showed significantly higher morphometric values except for anteroposterior gap (APG) and talus height (TaH) which were significantly higher in females (2.29 ± 0.80 vs 1.80 ± 0.61 mm and 13.01 ± 1.68 vs 11.87 ± 1.91 mm, respectively). There was significant increase in tibial arc length, APG, distance of level of MTiTh from anterior limit of mortise, distance of level of MTiTh from vertex of mortise, sagittal distance between tibial and talar vertices and sagittal radius of trochlea tali arc in old age group compared to young one. A significant decrease in tibial width, malleolar width, TaW and TaH was noted in old age group compared to young one.

Ankle joints of both sides are mostly symmetrical; however, there are significant differences in most morphometric values due to sex and age factors. These findings may be essential during side, sex and age determination.

In Egypt, the IUD is the most common contraceptive method since 1988 and has remained so despite a recent drop in its share from 59.9% in 2008 to 51.5% in 2014 in favour of hormonal methods, which increased from 19.7% for pills and 12.3% for injectables in 2008 to 27.4% and 14.5% in 2014 according to 2014 Egypt demographic and health survey (EDHS). The recent shift away from intrauterine contraceptive device (IUDs) to hormonal methods have contributed to increased discontinuation. This paper aims to answer three questions: To what extent does the method type influence the hazard of contraceptive discontinuation in Egypt? Is the interaction between method type and duration of use a predictor of the probability of discontinuation after controlling other variables? What are the other important background variables that affect the hazard of contraceptive discontinuation?

Using data from EDHS2014, separate multilevel discrete-time proportional hazard models for events of interest (abandoned use while in need, switched to another method in the month following discontinuation and method failure) were built.

Only IUD users are significantly less likely to abandon use while in need and to experience method failure and a reduced risk of switching. During the first 6–10 months of use, all types of discontinuation can be significantly reduced for all three methods. Demographic variables do not significantly affect abandonment but strongly affect switching and significantly affect failure. Socio-economic variables do not significantly affect abandonment and switching. Exposure to media has a significant effect on abandonment but not on switching. Community contraceptive prevalence rate strongly affects switching.

Results confirm that the counselling should be more intense during the first year of method use and should pay special attention to women who are 25 years old and above and those who have two or more children. Also, media campaigns are important and especially those addressing the issue of abandoning while in need.

The purpose of this study is two-fold. First is to explore the role of some customer personality traits in explaining customer satisfaction in mobile services. Second is to explore the relationship between satisfaction and loyalty of mobile services customers, mediated by attitude-to-brand considering the fierce competition and the fast industry growth.

The study used a cross-sectional design and a survey of mobile service customers. For the empirical analysis, the structural equation models were applied (partial least squares).

The results suggest that customers who are agreeable, neurotic and open to new experience are more likely to be satisfied with mobile services than other personality types. In addition, the satisfaction-loyalty link is fully mediated by attitude-to-brand. Hence, satisfaction is not a direct driver of loyalty in the mobile services business and loyalty is achieved when service providers simultaneously focussed on the customers’ satisfaction and their attitudes towards brands.

The study identified the personality trait drivers of customer satisfaction and the path to customer loyalty in the mobile services sector. With this information, mobile service providers should be better able to target and retain customers.

The study offers new insights into customer behaviour by using personality traits to identify requirements for achieving customer satisfaction, customer loyalty and attitude-to-brand.

El propósito de este estudio es doble. Primero, explorar el papel de algunos rasgos de personalidad del cliente para explicar su satisfacción en los servicios móviles. Segundo, explorar la relación entre la satisfacción y la lealtad de los clientes de servicios móviles, mediada por la actitud hacia la marca considerando la feroz competencia y el rápido crecimiento de la industria.

El estudio utilizó un diseño transversal y una encuesta de clientes de servicios móviles. Para el análisis empírico se utilizaron modelos de ecuaciones estructurales (PLS)

Los resultados sugieren que los clientes agradables, neuróticos y abiertos a nuevas experiencias tienen más probabilidades de estar satisfechos con los servicios móviles que otros tipos de clientes. Además, el vínculo satisfacción-lealtad está mediado por la actitud hacia la marca. Por lo tanto, la satisfacción no es un precursor directo de la lealtad en servicios móviles. La lealtad se logra cuando el proveedor de servicios se centra simultáneamente en la satisfacción del cliente y cuida la actitud hacia la marca.

El estudio identificó los rasgos de personalidad de los clientes que llevan a la satisfacción y el camino hacia la lealtad del cliente en el sector de los servicios móviles. Con esta información, los proveedores de servicios de telefonía móvil deberían estar mejor capacitados para dirigirse a los clientes y retenerlos.

El estudio ofrece nuevas perspectivas sobre el comportamiento del cliente al utilizar los rasgos de la personalidad para identificar los requisitos que permiten lograr la satisfacción del cliente, su lealtad y mejorar la actitud hacia la marca.

This paper aims to establish a fundamental and comprehensive understanding of non-fungible tokens (NFTs) by identifying and structuring common characteristics within a taxonomy. NFTs are hyped and increasingly marketed as essential building blocks of the Metaverse. However, the dynamic evolution of the NFT space has posed challenges for those seeking to develop a deep and comprehensive understanding of NFTs, their features and their capabilities.

Utilizing common guidelines for the creation of taxonomies, the authors developed (over 3 iterations), a multi-layer taxonomy based on workshops and interviews with 11 academic and 15 industry experts. Through an evaluation of 25 NFTs, the authors demonstrate the usefulness of the taxonomy.

The taxonomy has 4 layers, 14 dimensions and 42 characteristics, which describe NFTs in terms of reference object, token properties, token distribution and realizable value.

The authors' framework is the first to systematically cover the emerging NFT phenomenon. This framework is concise yet extendible and presents many avenues for future research in a plethora of disciplines. The characteristics identified in the authors' taxonomy are useful for NFT- and Metaverse-related research in finance, marketing, law and information systems. Additionally, the taxonomy can serve as an information source for policymakers as they consider NFT regulation.

This paper aims to highlight contrasts between the writing of young people in the UAE and Japan. For comparison, anthologies of 50-word short stories written in English, resulting from the Extremely Short Story Competition (ESSC) in each country are examined. These two ESSC anthologies were created under similar conditions in 2006. Analysis of the most frequently-appearing topics in each ESSC anthology provides insights into the daily life, general mindsets, behavior, preferences, values and culture of these two groups. These data help us to understand the everyday life and social context of young people in the UAE and Japan. Thematic analysis shows that youth in both countries are often preoccupied with seeking identity, and regard friends to be important. Both groups of young people also appear to appreciate the beauty of nature and feel affection towards living creatures. An identifying characteristic of Emirati youth is that they talk about death more often than do the Japanese writers; in addition, the ESSC anthologies indicate UAE society is remarkably family-oriented, with life being firmly connected to Islam and God. In contrast, Japanese youth show they are keen to engage in various hobbies and also like to express their romantic feelings and thankfulness for their environment. The ESSC was originally designed to develop students’ creative writing in English. This study explains that corpora generated by the ESSC may be used to illuminate the lives and societies of students living in disparate countries, with implications for planning and delivering locally appropriate education.

Crops are increasingly affected by drought; hence, the current study explored the potential role of three desert endophytic fungi, Aspergillus fumigatus, Aspergillus terreus and Talaromyces variabilis, in conferring drought tolerance in tomato plants.

Preserved endophytic fungi from a Rhazya stricta desert plant were adopted to obtain the required fungal treatment; tomatoes received fungal treatments directly in plastic trays and subsequently in pots. Drought was applied using 15% of PEG-6000 at two stages: flowering and fruiting. The following parameters were measured: pollen sterility, growth characteristics, morphological analysis and biochemical analysis, including proline, gibberellic acid (GA3) and chlorophyll measurements; thus, the data were analyzed statistically using SPSS software.

All applied endophytes significantly promoted pollen viability and tomato yield under stressed and nonstressed conditions. Interestingly, these endophytes significantly enhanced the number of trichomes under drought stress and promoted tomato fruit quality. The colonized tomato plants accumulated a high proline level under drought stress but lower than un-inoculated stressed plants. Also, a significant rise in growth characteristics was observed by A. fumigatus and A. terreus under normal conditions. Moreover, both raised GA3 levels under drought-stressed and nonstressed conditions. Also these two endophytes enhanced chlorophyll and carotenoid contents under drought stress. Fruit characteristics were enhanced by nonstressed T. variabilis and stressed A. fumigatus.

The present endophytic fungi provide impressive benefits to their host in normal and drought-stressed conditions. Consequently, they represent valuable sources as sustainable and environmentally friendly alternatives to mitigate drought stress.

The expansion of lifestyle and luxury markets has necessitated new marketing techniques. Recently, brand addiction has been a new topic in luxury repurchasing. The information reported in the literature regarding the effectiveness of brand addiction is insufficient and controversial. This research aimed to assess the role of brand addiction in Islamic consumers who purchase luxury smartphone brands.

Survey responses were collected from an online sample of 384 luxury consumers in Iran. The methods were evaluated using software (smart PLS 3) to test the hypothesis.

According to the uniqueness theory, the authors completed that brand addiction and consumer relationships are different and relative in each luxury product. The results positively determine that brand addiction has a more significant impact than brand jealousy, brand love and brand experience in repurchasing luxury consumers.

This study helps expand the literature on luxury repurchases and contends that brand addiction creates a new perspective in understanding behavioral addiction.

This paper provides insights for current and future marketers and managers, especially in Iran.

This investigation is the first study on the impact of different dimensions of brand addiction on luxury smartphone repurchase intention. In this regard, the findings of the study are important in the luxury market and extend current knowledge on repurchasing luxury products such as in Iran.

The purpose of this study is to introduce new tools to develop a more precise and focused bibliometric analysis on the field of digitalization in healthcare management. Furthermore, this study aims to provide an overview of the existing resources in healthcare management and education and other developing interdisciplinary fields.

This work uses bibliometric analysis to conduct a comprehensive review to map the use of the unified theory of acceptance and use of technology (UTAUT) and the unified theory of acceptance and use of technology 2 (UTAUT2) research models in healthcare academic studies. Bibliometric studies are considered an important tool to evaluate research studies and to gain a comprehensive view of the state of the art.

Although UTAUT dates to 2003, our bibliometric analysis reveals that only since 2016 has the model, together with UTAUT2 (2012), had relevant application in the literature. Nonetheless, studies have shown that UTAUT and UTAUT2 are particularly suitable for understanding the reasons that underlie the adoption and non-adoption choices of eHealth services. Further, this study highlights the lack of a multidisciplinary approach in the implementation of eHealth services. Equally significant is the fact that many studies have focused on the acceptance and the adoption of eHealth services by end users, whereas very few have focused on the level of acceptance of healthcare professionals.

To the best of the authors’ knowledge, this is the first study to conduct a bibliometric analysis of technology acceptance and adoption by using advanced tools that were conceived specifically for this purpose. In addition, the examination was not limited to a certain era and aimed to give a worldwide overview of eHealth service acceptance and adoption.
