For this purpose, the nature and conditions of bay al-salam contracts will be first discussed. Next, the paper will focus on the comparison between conventional banks and Islamic banks and should answer how bay al-salam can be used as a popular method in agricultural transactions in the country. The paper is based on secondary data which is to describe bay al-salam as future proceedings for Islamic banking. Evidence suggests Islamic banking is very much practiced like modern conventional banking with certain restrictions imposed by Sharia and addresses a large number of business requirements successfully. Thus, it’s time for us to implement Islamic banking (bay al-salam) on our agricultural arena and to get most benefits from them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bay%20al-salam" title="bay al-salam">bay al-salam</a>, <a href="https://publications.waset.org/abstracts/search?q=agricultural%20banking" title=" agricultural banking"> agricultural banking</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banking" title=" Islamic banking"> Islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=implementation" title=" implementation"> implementation</a> </p> <a href="https://publications.waset.org/abstracts/76421/implementation-of-bay-al-salam-in-agricultural-banking-of-bangladesh-an-islamic-banking-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76421.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">263</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> Modeling Salam Contract for Profit and Loss Sharing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dchieche%20Amina">Dchieche Amina</a>, <a href="https://publications.waset.org/abstracts/search?q=Aboulaich%20Rajae"> Aboulaich Rajae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Profit and loss sharing suggests an equitable sharing of risks and profits between the parts involved in a financial transaction.

Frosolini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The dynamic facility layout problem is a really critical issue in the competitive industrial market; thus, solving this problem requires robust design and effective simulation systems. The sustainable simulation requires inputting reliable and accurate data into the system. So this paper describes an automated system integrated into the real environment to measure the duration of the material handling operations, collect the data in real-time, and determine the variances between the actual and estimated time schedule of the operations in order to update the simulation software and redesign the facility layout periodically. The automated method- time measurement system collects the real data through using Radio Frequency-Identification (RFID) and Internet of Things (IoT) technologies. Hence, attaching RFID- antenna reader and RFID tags enables the system to identify the location of the objects and gathering the time data. The real duration gathered will be manipulated by calculating the moving average duration of the material handling operations, choosing the shortest material handling path, and then updating the simulation software to redesign the facility layout accommodating with the shortest/real operation schedule. The periodic simulation in real-time is more sustainable and reliable than the simulation system relying on an analysis of historical data. The case study of this methodology is in cooperation with a workshop team for producing mechanical parts. Although there are some technical limitations, this methodology is promising, and it can be significantly useful in the redesigning of the manufacturing layout. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20facility%20layout%20problem" title="dynamic facility layout problem">dynamic facility layout problem</a>, <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title=" internet of things"> internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=method%20time%20measurement" title=" method time measurement"> method time measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency%20identification" title=" radio frequency identification"> radio frequency identification</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/123996/automated-method-time-measurement-system-for-redesigning-dynamic-facility-layout" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Calculation Of Energy Gap Of (Ga,Mn)As Diluted Magnetic Semiconductor From The Eight-Band k.p Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khawlh%20A.%20Alzubaidi">Khawlh A.

Therefore, bridging the gap between humans and nature, the biophilia hypothesis emerges as a relatively theoretical and less comprehensively studied concept, though it has great potential for alternative design ideas. The research aims to enhance school playgrounds with biophilic design, positively impacting children's mental and physical well-being. This paper investigates the integration of biophilic design in school playgrounds and its influence on the well-being of children. It involves an analysis of three playgrounds in Alexandria, Egypt, each exhibiting varying degrees of biophilic design principles. The study investigates how these design elements enhance students' experiences by improving their surrounding environments. The research aims to develop a design framework and recommendations for creating or modifying playgrounds to enhance the physical and mental well-being of children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biophilic%20design" title="biophilic design">biophilic design</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20health" title=" physical health"> physical health</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20well-being" title=" mental well-being"> mental well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=children%E2%80%99s%20development" title=" children’s development"> children’s development</a>, <a href="https://publications.waset.org/abstracts/search?q=school%20playground" title=" school playground"> school playground</a> </p> <a href="https://publications.waset.org/abstracts/192052/enhancing-educational-environments-maximizing-school-playground-potential-through-biophilic-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">24</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">78</span> Degemination in Emirati Pidgin Arabic: A Sociolinguistic Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Rahman%20Mitib%20Altakhaineh">Abdel Rahman Mitib Altakhaineh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Salam%20Mohamad%20Alnamer"> Abdul Salam Mohamad Alnamer</a>, <a href="https://publications.waset.org/abstracts/search?q=Sulafah%20Abdul%20Salam%20Alnamer"> Sulafah Abdul Salam Alnamer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the production of gemination in Emirati Pidgin Arabic (EPA) spoken by blue-collar workers in the United Arab Emirates (UAE). A simple naming test was designed to test the production of geminates and a follow-up discussion was conducted with some of the participants to obtain the complementary qualitative analysis. The goal of the test was to determine whether the EPA speakers would produce a geminated or degeminated phoneme. A semi-structured interview was conducted with a subset of the study cohort to obtain participants’ own explanation where they degeminated the consonants. Our findings suggest that the exercising of this choice functions as a sociolinguistic strategy in a similar manner to that observed by Labov in his study of Martha’s Vineyard. The findings also show that speakers of EPA are inclined to degeminate consonantal geminates to establish themselves as members of a particular social group. Reasons for wanting to achieve this aim were given as: to claim privileges only available to members of this group (such as employment) and to distinguish themselves from the dominant cultural group. The study concludes that degemination in EPA has developed into a sociolinguistic solidarity marker. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sociolinguistics" title="sociolinguistics">sociolinguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=morphophonology" title=" morphophonology"> morphophonology</a>, <a href="https://publications.waset.org/abstracts/search?q=degemination" title=" degemination"> degemination</a>, <a href="https://publications.waset.org/abstracts/search?q=solidarity" title=" solidarity"> solidarity</a>, <a href="https://publications.waset.org/abstracts/search?q=Emirati%20pidgin%20Arabic" title=" Emirati pidgin Arabic"> Emirati pidgin Arabic</a> </p> <a href="https://publications.waset.org/abstracts/141676/degemination-in-emirati-pidgin-arabic-a-sociolinguistic-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141676.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">77</span> Effect of Different Concentrations of Polluted Water on Growth and Physiological Parameters of Two Green Algae Scenedesmus obliquus and Cosmarium leave</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yahia%20Mosleh">Yahia Mosleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Both Scenedesmus obliquus and Cosmarium leave were subjected to different concentrations (5, 10, 20, 50, and 80 %) of highly polluted water collected from Haddows drainage, which receives high amount of domestic sewage, and also the increasing agriculture run off and industrial effluent, then disbursed it in El-Salam fresh water canal.

However, the situation is different in the case of high concentrations, where it encourage the growth of Scenedesmus obliquus , meanwhile the same concentration were inhibited the growth and physiological activities of Cosmarium leave. Which indicated that, Scenedesmus obliquus tolerated high pollution better than Cosmarium leave. Finally it can be concluded that, different organisms, however, have different sensitivities to the same pollutants and the same organisms may be more or less damaged by different pollutant. Also, the inhibitory and stimulatory effects of different species varied with concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catalase%20activity" title="catalase activity">catalase activity</a>, <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid%20content" title=" ascorbic acid content"> ascorbic acid content</a>, <a href="https://publications.waset.org/abstracts/search?q=Scenedesmus" title=" Scenedesmus"> Scenedesmus</a>, <a href="https://publications.waset.org/abstracts/search?q=Cosmarium" title=" Cosmarium"> Cosmarium</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a> </p> <a href="https://publications.waset.org/abstracts/58194/effect-of-different-concentrations-of-polluted-water-on-growth-and-physiological-parameters-of-two-green-algae-scenedesmus-obliquus-and-cosmarium-leave" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58194.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">76</span> Impact of Cd and Pb Impregnation on the Health of an Adult Population Neighbouring a Landfill</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Cabral">M.

All the household and industrial waste arising from Dakar are stored in this open landfill without being covered and are therefore possible sources of Pb and Cd contaminated air emissions and lixiviates. The objective of this study is part of improving the health of the population neighboring Mbeubeuss by determining Pb and Cd concentrations both in environment and humans, and studying possible renal function alterations within the adults. Soil and air samples were collected in the control site (Darou Salam) and the waste dump neighboring site (Diamalaye II). Control and exposed adults were recruited as living in Darou Salam (n = 52) and in Diamalaye II (n = 77). Pb and Cd concentrations in soil, air and biological samples were determined. Moreover, we were interested in analyzing some impregnation (zinc protoporphyrin, d-aminolevulinic acid dehydratase) and oxidative stress biomarkers (malonedialdehyde, gluthatione status), in addition to several nephrotoxicity parameters (creatinuria, proteinuria, lactate dehydrogenase, CC16 protein, glutathione S-transferase-alpha and retinol binding protein) in blood and/or urine. The results showed the signiﬁcant Pb and Cd contamination of the soil and air samples derived from the landfill, and therefore of the neighboring population of adults. This critical exposure to environmental Pb and Cd had some harmful consequences for their health, as shown by the reported oxidative stress and nephrotoxicity signs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pb%20and%20Cd%20environmental%20exposure" title="Pb and Cd environmental exposure">Pb and Cd environmental exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=impregnation%20markers" title=" impregnation markers"> impregnation markers</a>, <a href="https://publications.waset.org/abstracts/search?q=landfill" title=" landfill"> landfill</a>, <a href="https://publications.waset.org/abstracts/search?q=nephrotoxicity%20markers" title=" nephrotoxicity markers"> nephrotoxicity markers</a> </p> <a href="https://publications.waset.org/abstracts/18333/impact-of-cd-and-pb-impregnation-on-the-health-of-an-adult-population-neighbouring-a-landfill" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> Calculation of Effective Masses and Curie Temperature of (Ga, Mn) as Diluted Magnetic Semiconductor from the Eight-band k.p Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khawlh%20A.%20Alzubaidi">Khawlh A.

Among the many types of DMS materials which have been investigated, Mn-doped GaAs has become one of the best candidates for technological application. However, despite major developments over the last few decades, the maximum Curie temperature (~200 K) remains well below room temperature. In this work, we have studied the effect of Mn content and strain on the GaMnAs effective masses of electron, heavy and light holes calculated in the different crystallographic direction. Also, the Curie temperature in the DMS GaMnAs alloy is determined. Compilation of GaMnAs band parameters have been carried out using the 8-band k.p model based on Lowdin perturbation theory where spin orbit, sp-d exchange interaction, and biaxial strain are taken into account. Our results show that effective masses, calculated along the different crystallographic directions, have a strong dependence on strain, ranging from -2% (tensile strain) to 2% (compressive strain), and Mn content increased from 1 to 5%. The Curie temperature is determined within the mean-field approach based on the Zener model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diluted%20magnetic%20semiconductors" title="diluted magnetic semiconductors">diluted magnetic semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=k.p%20method" title=" k.p method"> k.p method</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20masses" title=" effective masses"> effective masses</a>, <a href="https://publications.waset.org/abstracts/search?q=curie%20temperature" title=" curie temperature"> curie temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=strain" title=" strain"> strain</a> </p> <a href="https://publications.waset.org/abstracts/162897/calculation-of-effective-masses-and-curie-temperature-of-ga-mn-as-diluted-magnetic-semiconductor-from-the-eight-band-kp-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162897.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> A Variant of a Double Structure-Preserving QR Algorithm for Symmetric and Hamiltonian Matrices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Salam">Ahmed Salam</a>, <a href="https://publications.waset.org/abstracts/search?q=Haithem%20Benkahla"> Haithem Benkahla</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, an efficient backward-stable algorithm for computing eigenvalues and vectors of a symmetric and Hamiltonian matrix has been proposed.

Yield stress is presented in all results indicating the minimum stress that necessary to reach flow conditions. Connections between particle-particle is the reason for this yield stress, also, the addition of polyelectrolyte causes strong bonds between particles and water resulting in the aggregation of particles which required higher shear stress in order to flow.

The important future direction for liquid fuel desulfurization is adsorptive desulfurization technology due to its simplicity, mild operating condition, and low cost. In this work, the well-prepared Nickel NPs were incorporated in a highly porous metal-organic framework MIL-101(Cr)) to produce Ni/Cr-MOF composite. Besides, the synthesis of Ni/Cr-MOF in the presence of Bi₂MoO₆/AC to prepare Bi₂MoO₆/AC@Ni/Cr-MOF. All the prepared composites were synthesized via a facile technique under ambient conditions to remove organosulfur compounds. The XRD, FT-IR, SEM, and BET techniques were used to characterize the prepared composites. The desulfurization performance of real gas oil by Bi₂MoO₆/AC, Ni/Cr-MOF, and Bi₂MoO₆/AC@Ni/Cr-MOF was investigated at different adsorbent doses and contact times. Bi₂MoO₆/AC@Ni/Cr-MOF shows the highest desulfurization performance, with removal efficiency reached to 80% at optimum conditions for a contact time of 4 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desulfurization" title="desulfurization">desulfurization</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20oil" title=" gas oil"> gas oil</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-organic%20framework" title=" metal-organic framework"> metal-organic framework</a>, <a href="https://publications.waset.org/abstracts/search?q=sorption%20characteristics" title=" sorption characteristics"> sorption characteristics</a> </p> <a href="https://publications.waset.org/abstracts/171501/study-the-performance-of-metal-organic-framework-in-adsorptive-desulfurization-for-gas-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171501.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">80</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Feminist Evaluation: The Case of Mahatma Gandhi National Rural Employment Guarantee Act</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salam%20Abukhadrah">Salam Abukhadrah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research advocates for the use of feminist evaluation (FE) as a tool of great potential in policy and program assessment in relation to women’s empowerment.

A general rule of thumb is that the performance of the instrument must be higher than the performance of the unit under test in terms of accuracy and stability. The calibration and characterizing of mmWave transceivers are important pillars for testing commercial products. Using a Vector Network Analyzer (VNA) with a mixer option has proven a high performance as an approach to calibrate mmWave transceivers. However, this approach comes with a high cost. In this work, a reduced-cost method to calibrate mmWave transceivers is proposed. A comparison between the proposed method and the VNA technology is provided.

In order to provide an alternative to Interest based banking, financial transactions found in classical books of fiqh were employed. Musharakah, Mudarabah, Murabahah Salam, Ijara, and some other modes were adopted. These modes were modified so that they can be adopted for banking and satisfy the needs of customers. Since the inception of Islamic banking, these modes are being used and with the passage of time, are being molded and experimented with to cater different kinds of customers and requirements. Human efforts cannot be errorless. These modes too bear legal defects which need an in-depth scrutiny and refinement. The aim of this paper is to dig the basis and rulings of these modes in classical books of fiqh and analyze its modification and adoption in Islamic banking and the legal defects that these modes are bearing.

Thanks to its added values of knowledge-sharing, reuse and the ease of maintenance, this ontology tends to solve many problems. Of which we name the confusion between radiological procedures a practitioner might face while performing a patient radiological exam. Adding to it, the difficulties they might have in interpreting applicable patient radioprotection standards. Here, the ontology, thanks to its concepts simplification and expressiveness capabilities, can ensure an efficient classification of radiological procedures. It also provides an explicit representation of the relations between the different components of the studied concept.

Activity concentrations of uranium were studied by radiochemical separation procedures followed by alpha spectrometry and that of radium isotopes by gamma-ray spectrometry. The activity concentrations of 238U, 234U, 226Ra and 228Ra in water samples varied in range 3.3 - 22.5 mBq.L−1, 4.0 - 34.2 mBq L−1, 2.0 - 67.0 mBq L−1 and 2.0 - 30.2 mBq L−1, respectively. These values are comparable with those reported for many other countries in the world for different types of water. Based on the activity concentration results obtained in this study, the estimated annual ingestion dose rates for three different age groups (babies, children and adults) due to the ingestion of radium and uranium isotopes through drinking water are lower than the limit of intake prescribed by WHO. The annual doses exceed the recommended value of 0.1 mSv y-1 in one case for babies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mineral%20water" title="mineral water">mineral water</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20radioactivity" title=" natural radioactivity"> natural radioactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20dose" title=" radiation dose"> radiation dose</a>, <a href="https://publications.waset.org/abstracts/search?q=radium" title=" radium"> radium</a>, <a href="https://publications.waset.org/abstracts/search?q=uranium" title=" uranium"> uranium</a> </p> <a href="https://publications.waset.org/abstracts/60196/natural-radioactivity-in-tunisian-bottled-mineral-waters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Motives and Barriers of Using Airbnb: Findings from Mixed Method Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Mohammed">Ghada Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdel%20Salam"> Mohamed Abdel Salam</a>, <a href="https://publications.waset.org/abstracts/search?q=Passent%20%20Tantawi"> Passent Tantawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aimed to investigate the impact of motives and barriers for Egyptian users to use Airbnb as a platform of peer-to-peer accommodation instead of hotels on overall attitude towards Airbnb. A sequential mixed-methods approach was adopted to this study and it proposed a comprehensive research model adapted from both literature and results of qualitative phase and then tested via an online questionnaire. The findings revealed that, motives, price, home benefits, privacy, and online reviews significantly explained overall attitude towards Airbnb, while the main barriers were respectively: perceived risk and distrust in which they can predict the overall attitude. While from the subjective norms, only social influence can predict behavioral intention to use Airbnb. The study may serve as a practical reference for practitioners as well as researchers when developing programs and strategies to manage Airbnb consumers' needs and decision process. Some of the main conclusions drawn from this study are that variety was one of the major things that users like about Airbnb and the most important motives are the functional ones like price rather than the experiential ones like authenticity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airbnb" title="airbnb">airbnb</a>, <a
