Analysis of models for e-commerce adoption factors in developing countries

Small and Medium-sized Enterprises (SMEs) have a considerable role in most developing countries because they are able to develop and improve the economy. Whereas e-commerce is also a vital subject in the field of research, where they offer significant benefits for these countries. However, the adoption of e-commerce in developing countries by SMEs is low due to several factors, including the lack of a suitable model for the adoption of e-commerce. Therefore, some of the most widely used models for the adoption of e-commerce in developing countries were highlighted, which were Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT) established by Molla and Licker (2005), Technology Organisation Environment (TOE) Integration of TOE and TAM, Perceived eReadiness Model (PERM) and E-commerce Success Factors. The exploratory research was conducted in this study. Finally, some recommendations were reached that may give the researchers a better understanding of the adoption of e-commerce in developing countries which they have not yet started using e-commerce

A Case Report of Familial Benign Hypocalciuric Hypercalcemia: A Mutation in the Calcium-Sensing Receptor Gene

Familial benign hypocalciuric hypercalcemia (FBHH) is an autosomal dominant trait with high penetrance, clinically manifestating a relatively benign, lifelong, persistent hypercalcemia and hypocalciuria without hypercalcemic related complications. The calcium-sensing receptor (CaSR) plays an important role in the regulation of PTH secretion and calcium metabolism. Here we present a family with FBHH of an autosomal dominant inheritance. A heterozygous mutation of E297K (GAG→AAG, exon 4) of CaSR gene was found in 3 family members. To our knowledge, it is the first confirmed case of FBHH with CaSR gene mutation in Korea

On the Current and Future Outlook of Battery Chemistries for Electric Vehicles—Mini Review

As the electrification of the transportation industry is accelerating, the energy storage markets are trying to secure more reliable and environmentally benign materials. Advanced materials are the key performance enablers of batteries as well as a key element determining the cost structure, environmental impact, and recyclability of battery cells. In this review, we analyzed the state-of-the-art cell chemistries and active electrode and electrolyte materials for electric vehicles batteries, which we believe will dominate the battery chemistry landscape in the next decade. We believe that major breakthroughs and innovations in electrode materials such as high-nickel cathodes and silicon and metallic lithium anodes, along with novel liquid electrolyte formulations and solid-state electrolytes, will significantly improve the specific capacity of lithium batteries and reduce their cost, leading to accelerated mass-market penetration of EVs

Study of Date Palm Stem as Raw Material in Preparation of Activated Carbon

Activated carbon adsorbent was prepared using Omani date palm tree stem as a precursor. Precursor samples were subjected to thermal treatment (at 400, 500 and 600 oC) before or after impregnation with either H3PO4 (85 wt %) or KOH (3 wt %). The activated carbon obtained was characterized by BET (surface area and porosity), Gas Pycnometry (true density) and SEM (texture). Sample subjected to carbonization, without chemical activation, exhibited low surface areas ~ 1.0 m2/g at 400 and 500 oC and 124 m2/g at 600 oC. Further treatment of such samples with either the acid or the base did not show improvement in surface area or other properties. Impregnations of the precursor with acid before carbonization significantly improved the surface area to as high as 1,100 m2/g at a carbonization temperature of 500 oC. Thus, activated carbon with a moderate surface area could be produced from date palm stem using low carbonization temperature

Consumer awareness and actual buying behaviour of organic food in Algeria

Abstract Introduction. The adverse effects awareness of the chemicals misuse applied in food production is continuously increasing among consumers. In parallel, there is a rising trend in purchasing organically grown foods. Objective. This study aimed to evaluate Algerian consumers awareness and attitudes toward organic food products, and identify factors influencing their decision to purchase these organically grown foods. Material and methods. Survey data were obtained from 429 consumers via a 32-scale structured questionnaire, and evaluated with SPSS 25.0 and AMOS 25.0 using confirmatory factor analysis (CFA), and structural equation modeling (SEM). Hypotheses were verified by evaluating data via SEM, where mediating variables were attitude and purchasing intention. Results. The main reasons for Algerian consumers to consume organic food were health concerns, followed by environmentally friendly, pesticide-free, and better taste. Moreover, three factors namely health consciousness, subjective norms, and perception of availability were revealed to influence consumer buying behaviour towards organic food products. This occurred either by a direct effect such as availability perception or by a partial mediation of purchase intention, like subjective norms or by full mediating of attitude toward organic food, and purchase intention as the health consciousness factor did. Conclusion. The present study can guide and help agricultural policymakers to promote shifting to organic farming, which would benefit the ecosystem and human wellbeing. Furthermore, the report provides clear guidance for industry professionals who need to develop successful marketing strategies by addressing the main motivators of organic food consumption

Factors Influencing the adoption of e-commerce by small and medium-sized enterprises (SMEs) in Algeria: a qualitative study

Small and Medium sized Enterprises (SMEs) are regarded as the engine of the growth of the world economy. They had recently experienced rapid growth and improved their business activities in terms of customers’ number and revenue expansion when they began to embrace e-commerce and started using it in their business. However, although there is a growing interest in e-commerce, its use is still insufficient in Algeria. Therefore, this study aimed to identify the factors that influencethe adoption of e-commerce by SMEs in Algeria. This study adopts a qualitative methodology which involves in-depth, structured interviews to identify the factors that affect SMEs for the adoption of e-commerce in Algeria. The result of research found the main factors hindering the adoption of e-commerce by SMEs in Algeria are the e-payment methods, non-readiness of banks, lack of legal protection and lack in awareness of the benefits of e-commerce, as well as fear of risks. However, some other elements areless significant to influence the adoption of e-commerce. These research findings will give an addition in terms of bringing and giving a chance to the SMEs' leaders and the Algerian economic officials and a clear view of e-commerce practices. This can help them to design a strategy to remove barriers tactfully to its advantage

A model for e-commerce adoption by SMEs in developing countries

Small and Medium-sized Enterprises (SMEs) are regarded as the backbone of the growth of the world economy. They had recently experienced rapid growth and improved their business activities in terms of customer numbers and revenue expansion when they began using e-commerce in their business. However, the adoption of e-commerce in developing countries by SMEs is low due to several factors, including the lack of a fit model for the adoption of e-commerce. Therefore, some of the most widely used models for the adoption of e-commerce in developing countries were highlighted, that were Theory Planned Behaviour (TPB), Theory Reasoned Action (TRA), Diffusion of Innovation Theory (DOI), Technology Acceptance Model (TAM), Unified Theory of Acceptance and Use of Technology (UTAUT), Technology Organisation Environment (TOE), Integration of TOE and TAM, Perceived eReadiness Model (PERM). The exploratory research was conducted in this study. Finally, a model was developed and some recommendations were reached that may give the researchers a better understanding of the adoption of e-commerce in developing countries that they have not yet started adopting e-commerce as an integrated web
