The transformation of the traditional desert houses in "Al-Arish" old settlement through various cultures and civilizations is a particularly unique case. The way the traditional house absorbs new members and accommodates new nuclear families at the same plot area is an interesting case. Previous researches have examined configuration characteristics of the traditional houses in "Al-Arish". This paper will focus on the interpretation of morphology and social structure. It is almost a truism within space syntax research that the sociologically significant aspects of a building are directly reflected in its spatial configuration. (Sonit Pafna, 2001). In the selected area for the case study, there are different house types referring to three main time periods; 1) pre-occupation period (type-a) unchanged original house forms, 2) occupation period (type-b); and 3) post-occupation period (type-c). House plans were examined using space syntax methods, and relationships to shifts in social traditions and family structures were analyzed. Typically the guest courtyard and the family courtyard, as the central living spaces, have always been an essential part of the social life of the society, their transformation were emphasized. Results of the study related to transformation process and the feedback of the changed social structure and the impact of the Islamic inheritance roles on the house forms were simulated and discussed for further research into accommodating solutions for contemporary needs of the inhabitants as guidelines for current housing practices.* The research aims to sketch a way of understanding the impact of the social rules and traditions on the spatial pattern, in other words detecting the society's impact on space. The paper intends to examine and explore the transformation process of Sinai's traditional houses and the changed social behavior from living within complex family structure to nuclear family structures with segregated household.

The paper aims to the preparation of novel disperse dye based on azo salicylaldehyde derivatives TF-A [2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde] and full evaluation of their use as disperse dye TF-ASC [bis 2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde Schiff base with 4,4'-methylenedianiline] for dyeing polyester fabric at various conditions.

The dispersed dye was synthesized via Schiff base condensation in the presence of ceric ammonium nitrate cerium ammonium nitrate 10 mmole% as an eco-friendly catalyst at room temperature. The chemical structure of the prepared dye was characterized via elemental analysis, Fourier-transform infrared spectroscopy, 1H- and 13 C-NMR spectroscopic analysis tools. This study thoroughly examined the dyeing of disperse dye TF-ASC on polyester at various conditions. The characteristics of dyed polyester fabric were measured by colour measurements, as well as light, washing, crock fastness and finally, colour strength. The discrete fourier transform (DFT) theoretical studies, including E_HOMO, E_LUMO and optimized geometrical structure, were assumed and discussed in detail.

The results showed that the synthesized organic dye TF-ASC was highly functional and appropriate for this kind of dyeing method. The dyeing fabrics obtained from disperse dye TF-ASC, properties possess high colour strength as well as good overall fastness properties. These dyes had a high affinity for polyester fabric, with just a tiny change in dye affinity when the pH was changed, even under alkaline circumstances. The dye levelness and shade depth of the colour results were good, and there were a variety of hues from light brownish yellow to deep brownish yellow. The results obtained from DFT computational studies such as E_HOMO, E_LUMO, optimized structure, diploe moment µ and electrophilicity index deduced that prepared organic dye TF-ASC is more applicable as a dispersed dye.

This research is significant because it provides a new dye for dyeing polyethylene terephthalate fibres with exceptional brightness and levelness; the method of preparation is a useful pathway due to its being known as a green chemistry method.

This study aims to investigate the nutrient composition and cholesterol content of most popular fast foods sold in Qena city, Egypt with reference to their trans fatty acids contents.

Total 80 samples of fast foods were collected from various fast food restaurants in Qena city, Egypt. The samples were investigated for their nutritive quality by measuring moisture, protein, fat, ash, carbohydrate and energy content as described by the association of analytical chemists. The cholesterol content was determined using a spectrophotometer, while trans fatty acids were analyzed by gas chromatography using standard methods.

The study revealed a wide variation in the composition and nutritive value. On a fresh weight basis, moisture, protein, fat, carbohydrate and ash ranged from 45.9-55.0 (P < 0.001), 15.0-22.3 (P < 0.001), 13.1-15.7 (P = 0.034), 6.0-16.2 (P < 0.001) and 2.2-3.5 (P < 0.001), %w/w, respectively. The fast foods were very energy dense with calorie content varying from 236.5-281.1 (P < 0.001), Kcal/100 g. The mean values of cholesterol were between 15-17 mg/100 g (P = 0.398). The findings showed that fast foods had high total trans fatty acids content exceeding the Danish legal limit of 2 g/100 g of fat being in the range of 3.5 to 11.3 g per 100 g fat (P = 0.379). Elaidic acid is the predominant trans-isomer in industrially produced trans fatty acids. The concentrations of elaidic acid were high in all samples examined (P = 0.942).

This study has established the fact that fast foods are associated with high total energy intake, high intake of fat, trans fat and a higher proportion of calories being derived from total fat and trans-fat. Therefore, it is recommended to limit the intake of fast food.

The purpose of this paper is to assess the vulnerability of the aquifer using two models of analysis (DRASTIC and GOD) that were applied in practice in the regions of Bir Chouhada, Souk Naamane and Ouled Zouai in the district of Oum El-Bouaghi.

This study aims to determine the most adequate methods to ensure the protection of the Bir Chouhada, Souk Naamane and Ouled Zouai aquifer from pollution using vulnerability assessment. The application of the DRASTIC and GOD models made this evaluation possible.

The analysis of the both maps of vulnerability, resulting from the application of the two methods (DRASTIC and GOD), has revealed several classes of vulnerability that are no-, low-, medium- and high-vulnerable area. High DRASTIC vulnerability values vary between 145 and 178, and those of GOD vary between 0.07 and 0.57. It is observed that vulnerability increases from the center toward the eastern part of the plain; this is confirmed by the repartition of nitrate contents. The impact of the hydraulic conductivity on vulnerability to pollution is more significant than those of the vadose zone and the aquifer media. This is well observed when considering the single-parameter sensitivity analysis.

The text deepens the understanding of the vulnerability assessment and quality of the aquifer and the groundwater. The present study can be used for the assessment and the management of groundwater.

There is a substantial body of the literature on the role of destination image in tourist’s future behavior, however, the majority of these studies were conducted in “Sun-and-Sand” destinations, and only a few studies have addressed this research topic in “Historical-and-Cultural” destinations context. The purpose of this paper is to fill this gap by investigating the impact of Egypt’s perceived destination image – as one of the most famous cultural and historical destinations in the global tourism arena – and tourist satisfaction on tourists’ future behavioral intentions.

The study adopted a mixed methodology (a combination of survey questionnaire based on a quota sample from 400 tourists, as well as semi-structured interviews with tourists from different nationalities). Data were analyzed using exploratory factor analyses, confirmatory factor analysis and structural equation modeling.

The results related to the impact of the perceived destination image are discussed. Also, some practical implications related to destination management organizations are highlighted.

The study contributes theoretically and empirically to destination image literature, by improving the understanding of the multi-dimensional nature of destination image and its impact on revisit intention and word-of-mouth recommendation. Also, it helps in guiding Egypt’s destination image management activities to rebuild Egypt’s image as a safe destination for all the world’s travelers.

This paper aims to examine the value relevance (VR) of accounting information (AI) presented by Egyptian listed non-financial companies. Further, the study investigates the influence of institutional ownership on the value relevance of AI in a developing market, namely, the Egyptian market.

The study uses data from 2014 to 2017 with a total of 248 observations and analyses the data using regression analysis. Data are collected from the nonfinancial companies listed on the Egyptian Stock Exchange.

The authors found that the AI reported by the Egyptian listed non-financial companies is value relevant. Regarding the influence of institutional ownership, it is found to significantly impact the VR of AI reported by the sample companies. This model investigated the effect of corporate size and financial leverage as controlling variables and found that they have an insignificant influence on the VR of AI.

The current study findings enrich the literature by enhancing the understanding regarding institutional owners’ impact on corporate value. Further, bringing evidence from an emerging market can have implications for accounting researchers interested in addressing other emerging markets with similar contextual and institutional environments.

The purpose of this study is to examine the effect of the audit committee (AC) independence, financial expertise, internal audit function, audit quality and ownership concentration on earnings quality (EQ) and, consequently, ascertain whether the AC’s independence and financial expertise has a moderating effect on the relationship between internal audit function and EQ.

The study sample is 508 firms listed on the Main Market of Bursa Malaysia (formerly known as Kuala Lumpur Stock Exchange) for the years 2009 to 2012. EQ was measured using two modified Jones models of discretionary accruals.

The findings reveal that the independence of AC and investment in internal audit function, as well as the Big4 audit firm, are related to greater EQ. Ownership concentration is found to be associated with lower EQ. The study provides evidence that AC’s independence moderates the relationship between internal audit function (investment in and sourcing arrangements of internal audit function) and EQ. It also shows that AC’s financial expertise moderates the relationship between sourcing arrangements of internal audit function and EQ.

This study extends the prior related literature by examining the AC’s independence and financial expertise as moderating variables on the relationship between internal audit function and EQ.

Policymakers might use the findings regarding EQ in relation to governance practices, to recognize the important roles played by the AC’s independence and financial expertise on the effectiveness of internal audit function with EQ.

This study uses the agency theory and resource dependence theory to provide empirical evidence on the impact of internal audit function and AC on EQ in the ownership concentration environment.

Prior tourism literature neglected the negative motivational or attitudinal elements influencing individuals’ travel destination decisions. This study aims to examine the relationships between animosity, ethnocentrism, attitude, subjective norm (SN), perceived behavioural control (PBC), destination overall image (DOI) and destination visit intention (DVI).

A quantitative approach was used using a survey methodology involving 402 student responses. The proposed hypotheses were empirically tested with SPSS and AMOS.

The results demonstrated that animosity and ethnocentrism negatively influenced DOI and DVI. A positive relationship was reported between attitude, DOI and DVI. Additionally, SN and PBC positively influenced DVI. Ethnocentrism, PBC and DOI were also identified with statistically significant differences through gender. Meanwhile, statistically significant differences in attitude, PBC, DOI and DVI were evident between postgraduate students and the counterparts.

This study extends the existing knowledge on how animosity and ethnocentrism influenced DOI and DVI in tourism literature and benefitted Western tourism and key stakeholders in tourism.

本研究扩展了关于敌意和民族中心主义如何影响旅游文献中和DVI的现有知识, 并有利于西方旅游业和旅游业主的发展。

Elección de Destino de los Viajeros entre Estudiantes Universitarios en China en medio de COVID-19: Ampliar la Teoría del Comportamiento Planificado

La literatura turística anterior descuidó los elementos motivacionales o actitudinales negativos que influyen en las decisiones de destino de viaje de las personas. Este estudio examinó las relaciones entre la animosidad, el etnocentrismo, la actitud, la norma subjetiva (SN), el control de comportamiento percibido (PBC), la imagen general de destino (DOI) y la intención de visita de destino (DVI).

Se empleó un enfoque cuantitativo utilizando una metodología de encuesta que implicaba 402 respuestas de los estudiantes. Las hipótesis propuestas se probaron empíricamente con SPSS y AMOS.

Los resultados demostraron que la animosidad y el etnocentrismo influyeron negativamente en doi y DVI. Se informó de una relación positiva entre la actitud, doi y DVI. Además, SN y PBC influyeron positivamente en el DVI. El etnocentrismo, el PBC y el DOI también se identificaron con diferencias estadísticamente significativas a través del género. Mientras tanto, las diferencias estadísticamente significativas de actitud, PBC, DOI y DVI eran evidentes entre los estudiantes de posgrado y las contrapartes.

Este estudio amplía los conocimientos existentes sobre cómo la animosidad y el etnocentrismo influyeron en el DOI y la DVI en la literatura turística y beneficiaron al turismo occidental y a las principales partes interesadas en el turismo.

The aim of this current study is to investigate the effects of knowledge management capabilities – knowledge infrastructure capability and knowledge processing capability – on organizational agility and business performance. This study also examines organizational agility as an underlying mechanism between knowledge management capabilities and business performance relationship.

The data were collected from one hundred and sixty-nine organizations. Partial least squared (PLS)–based structural equation modeling (SEM) technique was employed to test the study hypotheses. The analysis was performed in WarpPLS 6.0 software.

Results revealed that both dimensions of knowledge management capabilities positively influence organizational agility and business performance. In addition to the direct effect, knowledge management capabilities also have an indirect effect on business performance mediated through organizational agility.

This study attempts to develop an integrated framework to conceptualize a capability–capacity–performance relationship, where it suggests that knowledge management capabilities are important organization-level capabilities which facilitate organizations to develop necessary capacities i.e. organizational agility to successfully perform business activities.

The findings help the managers to understand the contribution of knowledge management capabilities towards business performance. The findings imply that business performance can be enhanced by development of a culture - enabled by a knowledge-oriented structure and technology – that encourages knowledge sharing among employees because when employees are not sharing information, they are prone to repeating the same mistakes which they and other people have already committed. Likewise, strategies such as mentoring cross training, business process empowerment and technical training programs allow employees to gain business knowledge and foster organizational agility.

Novelty of this study is to develop and empirically test an integrated framework of a capability–capacity–performance relationship. It suggests that knowledge management capabilities (firm capability) enable organizations to develop organizational agility (firm capacity) which in turn enhances performance.

The aim of this paper has twofold: (1) to explain and compare the financial evolution of Islamic and conventional banking sector in the Gulf Cooperative Council (GCC) countries before and during the COVID-19 pandemic and (2) to explore the key success factors that might affect Islamic and conventional banks performance before and mainly during COVID-19 pandemic period.

Orbis Bank Focus database and annual financial reports are used to collect financial information of Islamic and conventional banks in GCC countries over four years: 2017, 2018, 2019 and 2020. Descriptive statistics, T-test, multiple regression, and 2SLS and GMM models are employed to analyze the financial structure and performance of Islamic and conventional banks before and during the COVID-19 pandemic period.

Results of this study reveal that (1) there is a significant difference between Islamic banks and conventional banks during the crisis of COVID-19, where the conventional banks have presented a higher level of financial performance and financial liquidity than their Islamic counterparts, (2) conventional banks have revealed higher capacity to manage their financial risk during the crisis period, and (3) a high level of non-performing loan, high inflation rate and high percentage of non-important cost have a negative impact on the financial performance of Islamic banks mainly during the pandemic period of COVID-19. However, the result indicates that a high level of liquidity risk increased the performance of Islamic banks but this impact falls sharply during the pandemic period.

This study provides information that supports investors, regulators and executive managers in GCC countries. A well-structured balance sheet would improve the financial performance and risk management of the banking sector in GCC countries, especially in times of crisis and pandemics.
