The accreditation process of academic programs is being used more to recognize program quality and identify areas for improvement based on rigorous standards. This study aims to use the standards of the Council for Accreditation of Educator Preparation (CAEP) as a theoretical and analytical framework to examine the effectiveness and areas for improvement of the teacher education program at Sultan Qaboos University in Oman.

A multiple case-study design is used to investigate the cases of 16 novice program completers. Data is collected using nonparticipant observation and semistructured interviews with 48 key stakeholders: program completers, their educational supervisors and school principals.

Results show that, overall, the program is effective in preparing future teachers to enter the teaching profession, especially in the subject and pedagogical content knowledge, and that stakeholders are generally satisfied with the program. However, about a third believe the program lacks relevance to the responsibilities teachers face on the job and some “technical” skills needed in practice.

First, the findings are limited by the small number of completers’ cases from one teacher education program. Therefore, the authors recommend that future studies should include larger samples of novice teachers graduating from different teacher education programs. Second, the study is limited by focusing only on stakeholders’ perspectives, and teacher observation through CAEP informed categories related to standards 1, 4 and 5. So future research can tell more to the story by uncovering other CAEP standards to provide a more comprehensive view.

The findings of this study are expected to contribute to the existing pool of knowledge on the utility of using international accreditation frameworks, not only as a means to measure the effectiveness of teacher education programs but also to develop such programs according to an internationally recognized set of quality standards. The results may also contribute to the discourse on whether the Madonlization of CAEP standards is a useless business for Arabic-speaking countries.

As elsewhere in the Arab region, education has been placed at the core of the Oman 2040 vision, which prioritizes the improvement of educational outcomes as Oman’s gateway to becoming a developed country. Therefore, it has become clear that teacher education programs need to be subject to scrutiny to ensure that they produce highly qualified teachers. While reform initiatives have raised concerns about the quality of teacher performance in Omani schools, little attention has been given to the effectiveness of teacher education programs in the country.

These results are discussed through three main themes related to the role of teacher preparation programs in the Arab region from a standards-based perspective: they need to be viewed as a rite of passage for all teachers to provide them with only the threshold competence to commence the professional teaching performance, there is a need for more authentic and safe learning experiences in these programs, and finally, there is a need for continuous adjustment of courses in these programs to perfect the “potion” that makes them more effective and relevant.

This study aims to investigate a mediated-effects model of organizational support and citizenship behaviour. The model proposes organizational support as an antecedent of citizenship behaviour and commitment to change (CTC) as a mediator in the organizational support–citizenship behaviour relationship.

Cross-sectional survey data were collected from university faculty (n = 221) and analyzed using structural equation modelling.

The findings showed that organizational support significantly contributes to increased citizenship behaviour and commitment of university faculty to program accreditation as an enterprise change process. The authors conclude that university-level organizational support shapes faculty’s CTC both directly and indirectly. The findings have significant practical implications for higher education institutions (HEIs) where new practices that aim at improving institutional effectiveness are embraced.

The study is cross-sectional (i.e. one-time data collection), which restricts the ability to make generable inferences about cause-and-effect relationships. Although the authors tested a model, longitudinal research is needed to unpack the processes of organizational support, commitment and citizenship behaviour. During enterprise change management, organizations work tirelessly to build and maintain citizenship behaviour. Therefore, considering citizenship behaviour in relation to other processes over time is important. However, relying on one source of data may represent another limitation, which increases concerns about common method bias in the current investigation.

The study findings offer a number of implications to HEIs in contexts where accreditation is perceived as an enterprise change process. Universities, similar to any other organizations, rely consistently on methods and mechanism through which employees’ professional performance, engagement and involvement can be enhanced. Accreditation has always been examined by exploring externally focused variables such as global reputation, organizational prestige and international prominence. The present study, however, draws attention to how perceived organizational support (POS) may be an equally important lever that needs to be considered before accreditation is introduced in HEIs. University chancellors, deans and other university leaders can directly influence organizational support by creating a system that weighs the extra work needed, the human resources and the incentives, and developing a plausible action plan.

It is unlikely that all faculty members will maintain quality relationship with the university leadership and immediate leaders such as department chairpersons or the college dean. This unlikelihood increases during crisis and change time. The study findings showed that POS contributes significantly to organizational citizenship behaviour. Therefore, it could be argued that the resistance to change that tends to be associated with accreditation can be mitigated by showing employees that support is accessible and attainable from up-line and immediate leaders. The findings suggest that commitment serves as an integral mediating mechanism between organizational support and citizenship behaviour. Indeed, commitment can be fully examined in practice from the perspective of its three-pronged structure (i.e. affective, continuance and normative). The findings provide credence to the notion that accreditation as an enterprise change process cannot be achieved without employee commitment and organizational support.

As a result of adopting globalized techniques, HEIs in Arab nations have undergone significant changes. In the Arab context, the adoption of academic program accreditation in HEIs has been seen as an enterprise change process with both supporters and detractors. In other words, implementing new systems or procedures results in changes that might upend personnel at any given organization. Therefore, it is contended that how well an organization responds to resistance to change will likely depend on the interaction of organizational, contextual and individual-related characteristics.

This study aims to investigate profoundly the protection of oil painting from deterioration using molybdenum trisulphide quantum dots (MoS3 QDs) against microbe, dirt accumulation and ultraviolet (UV) degradation.

The protection of painting against different deterioration factors necessitates the sustainable methods and advanced techniques. Scanning electron microscopy and transmission electron microscopy have been used to investigate the morphological structure of the painting and MoS3 QDs, respectively, and optical microscopy was used to examine antibacterial activity of MoS3 QDs towards different types of bacteria. To investigate the protection of painting against deterioration, the Fourier transform IR spectroscopy (FTIR) was used to investigate the paintings left in open air for a year. Chemical composition and crystal structure of MoS3 QDs have been studied using X-ray diffraction and X-ray photoelectron spectroscopy analysis, respectively.

The addition of MoS3 nanoparticles into painted coatings enhances the durability of linseed oil-based paintings toward UV ageing regarding the change in colour which confirmed by FTIR analysis. The protection of oil painting opposed to various deterioration factors was developed by involving of MoS3 QDs in the coating of the painting. Antibacterial effect of MoS3 QDs was tested against different types of bacteria such as Pseudomonas aeruginosa confirming that the MoS3 QDs involved in the coatings of oil paintings produces a high protection layer for the paintings against several microbial attacks. In addition, coatings containing MoS3 QDs reduce the accumulation of dirt on oil paintings when subjected to open air for a year.

The novel MoS3 QDs was used to form a protective and transparent coating layer for the oil painting to overcome the deterioration, displays the promising protection and can be applied for different oil paintings.

In the context of architecture education, design studio projects usually start with “research” on the design theme and the context, but often there is no strong link between this research and its application in the project and the resultant design product. This paper explores strategies which link knowledge acquisition and knowledge application in design studio teaching and learning.

These strategies have been applied in several design studios and master’s theses and involve sixteen years of research by the author through observation, surveys and analysis of student work.

The results show that these strategies are not limited to the design studio, with more than half of them (eight out of fourteen) also applicable in theoretical subjects that sit outside the design studio unit and generate knowledge of relevance to studio projects. As such, the paper advocates for a multi-level approach involving the following: course design and curriculum development, teaching and learning pedagogies and organizational decisions regarding the deployment of staff as for collaborative team-based teaching.

The results also recognize the relevance of problem-based and project-based learning to the broader higher education context and its dependence on a collaborative approach.

This paper which synthesizes this work contributes to the literature on architecture pedagogy, specifically that related to the integration of theoretical and practical subjects.

The Egyptian Premier League (EPL) holds a prominent place in Egypt’s sporting culture and serves as the stage for some of Africa’s most competitive soccer clubs. However, the actual competitive balance in this league has come under scrutiny in recent years as the two historically dominant Cairo clubs, Ahly and Zamalek, continue to retain the EPL championship. A major concern is that the competitive imbalance of the EPL may actually be hampering the league’s progress and the progress of soccer in Egypt. In order to more closely assess this situation, the purpose of this paper is to use historical EPL performance data to conduct a series of competitive balance analyses on league results from 1948 to 2014. The findings revealed that competition in the league is almost nonexistent as Ahly and Zamalek continue to enjoy a number of direct and indirect financial benefits that are unrealized by their competitors. The dominance of these clubs has compromised the elements of match uncertainty and drama that are traditionally viewed as being important to the prestige and financial achievements of leagues and teams. Discussion is therefore offered for how the EPL could go about resolving some of its organizational and competitive balance issues.

This study adopted four basic measures of competitive balance to conduct descriptive analyses on EPL data that were collected from egyptianfootball.net and the Rec Sport Soccer Statistics Foundation. These analyses began with the EPL’s inaugural season (1948-1949) and extended to the conclusion of the 2014-2015 season. During this timeframe, seven seasons were canceled due to global and political tensions and four more went unfinished. Because these seasons were excluded, the total sample size consisted of 56 seasons, each of which contained between 10 and 24 EPL teams. The data were analyzed using variations of the following competitive balance measures: the range and standard deviation of winning percentages, the ratio of the standard deviation/Noll-Scully approach, the Herfindahl-Hirschman Index, and five-club concentration ratio.

The results confirmed that the league is largely imbalanced, leading the authors to recommend systemic and structural changes that could help promote competitive balance in the league. The call for competitive balance in the EPL was bolstered by a literature review of studies that advocated for parity in professional sports leagues. In the end, the researchers recommend the EPL to improve its organizational policies and consider a revised revenue-sharing system that would allow the small-market teams to survive and thrive.

The EPL holds a prominent place in Egypt’s sporting culture and serves as the stage for some of Africa’s most competitive soccer clubs. The primary purpose of this study was to perform a series of competitive balance analyses on EPL results from 1948 to 2015 in an effort to better understand the various degrees of competitiveness in the league during this time.

Iranian history, with roots in the oldest civilizations in western Asia, has provided significant heritage, both tangible and intangible, allowing the country to be considered as a major cultural tourism destination for both nationals and foreigners. The focus on Iranian history and heritage aims to confirm the country’s potential for attracting international tourists, while a negative image prevails abroad of a radical theocratic regime with a hostile internal political environment, alongside the instable geopolitical situation of the region. However, the changing political situation, now more secure and safe, allows an attempt to remove these prejudices, which may be achieved through the promotion of heritage and cultural tourism.

The study examines health care inequities in viral load testing among hepatitis C (HCV) antibody-positive patients. The analysis predicts whether individual and census tract sociodemographic characteristics impact the likelihood of viral load testing.

This a study of 26,218 HCV antibody-positive patients in Orange County, California, from 2010 to 2020. The case data were matched with the 2017 American Community Survey to help understand the role of neighborhood socioeconomic characteristics in testing for viral load. Multivariable logistic regression was used to predict the probability of ever testing for HCV viral load.

Thirty-six percent of antibody-positive persons were never viral load tested. The results show inequalities in viral load testing by sociodemographic factors. The following groups were less likely to ever test for viral load than their counterparts: (1) individuals under 65 years old, (2) females, (3) residents of census tracts with lower levels of health insurance enrollment, (4) residents of census tracts with lower levels of government health insurance, and (5) residents of census tracts with a higher proportion of non-white residents.

This is a secondary database from public health department reports. Using census tract data raises the issue of the ecological fallacy. Detailed medical records were not available. The results of this study emphasize the social inequality in viral load testing for HCV. These groups are less likely to be treated and cured, and may spread the disease to others.

This chapter is unique as it combines routinely collected public health department data with census tract level data to examine social inequities associated with lower rates of HCV viral load testing.

This study aims to show the dyeing behaviour of polyester fabrics using four novel heterocyclic disperse dyes.

The four dyes were synthesized based on 5, 5'-(1, 4-phenylene) bis (1, 3, 4-thiadiazol-2-amine) as a diazonium compound. The UV/Vis absorption spectroscopic data of these disperse dyes while dyeing polyester fabrics were investigated. Following this, the dyeing properties of these dyes on polyester fabrics were investigated under acid condition.

The results showed that increasing the dyeing temperature from 80°C to 100°C led to an increase in dye uptake for all dyes, but further increases of the temperature to 130°C led to higher dye uptake for dye 3 as the dye exhaustion increased by about 50% from 55.9% to 91.4%.

This study is important as it introduces new dyes for the dyeing of polyethylene terephthalate (PET) fibres with colours that range from yellowish orange to bluish yellow and scarlet red and all with excellent brightness, levelness and depth of shade.

This work aims to determine the best linear model using an artificial neural network (ANN) with the imperialist competitive algorithm (ICA-ANN) and ANN to predict the energy consumption for land leveling.

Using ANN, integrating artificial neural network and imperialist competitive algorithm (ICA-ANN) and sensitivity analysis (SA) can lead to a noticeable improvement in the environment. In this research, effects of various soil properties such as embankment volume, soil compressibility factor, specific gravity, moisture content, slope, sand per cent and soil swelling index on energy consumption were investigated.

According to the results, 10-8-3-1, 10-8-2-5-1, 10-5-8-10-1 and 10-6-4-1 multilayer perceptron network structures were chosen as the best arrangements and were trained using the Levenberg–Marquardt method as the network training function. Sensitivity analysis revealed that only three variables, namely, density, soil compressibility factor and cut-fill volume (V), had the highest sensitivity on the output parameters, including labor energy, fuel energy, total machinery cost and total machinery energy. Based on the results, ICA-ANN had a better performance in the prediction of output parameters in comparison with conventional methods such as ANN or particle swarm optimization (PSO)-ANN. Statistical factors of root mean square error (RMSE) and correlation coefficient (R²) illustrate the superiority of ICA-ANN over other methods by values of about 0.02 and 0.99, respectively.

A limited number of research studies related to energy consumption in land leveling have been done on energy as a function of volume of excavation and embankment. However, in this research, energy and cost of land leveling are shown to be functions of all the properties of the land, including the slope, coefficient of swelling, density of the soil, soil moisture and special weight dirt. Therefore, the authors believe that this paper contains new and significant information adequate for justifying publication in an international journal.

This study aims to the synthesis of some novel 4-arylazo-3-hydroxythiophene analogues containing sulphapyridine and sulphathiazole dyestuffs and studying their application in dyeing polyester fabrics and rendering their antibacterial efficacy.

Simultaneous dyeing and antibacterial finishing for polyester fabric using a new antibacterial disperse dye having a modified chemical structure to thiophene dyes were studied. Construction of the thiophene dyes was carried out by diazo-coupling of diazotized sulphonamide-containing heterocyclic rings sulphapyridine and sulphathiazole with ethyl α-phenylthiocarbamoyl-acetoacetate followed by cyclizing the produced 2-arylazo-thioacetanilide with various α-halogenated reagents. All newly synthesized compounds were characterized by elemental analysis and extensive study of their spectral data (IR and ¹H-NMR). The dyeing characteristics of these thiophene dyestuffs were evaluated at optimum conditions. Antibacterial activities of the obtained thiophene dyes were studied against some Gram-positive and Gram-negative bacteria.

The synthesized thiophene-containing sulphonamides dyes were applied on polyester fabric. The modified dyes exhibited a good fastness properties and antibacterial efficacy against some Gram-positive and Gram-negative bacteria. Synthesized dyes showed higher antibacterial potency than the reference standard drug.

Synthesis of these disperse azo dyes for textile dyeing had never been reported previously.

The dyestuffs derived from thiophene are reasonable azo disperse dyestuffs giving good all-round fastness properties on polyester fabrics.

Thiophene dyes are used for dyeing polyester fabrics with brilliant colour and good fastness properties. The presence of sulphonamides moieties increase their fastness properties and elevate their antibacterial properties. Moreover, they can be used as antimicrobial finish due to their bactericidal properties on dyed textiles. This work afforded a new thiophene colorant that can be used in many different uses like polyester packing, thread Surgery, blends and other uses in medical textile.
