Medical schools aspire to graduate doctors who are competent in interpreting, conducting and publishing scientific research. Hence, the purpose of the paper is explore the impact of a structured compulsory community-oriented, project-based research program in the undergraduate medical curriculum on medical graduates’ future careers, publications and motivation for scientific research.

An online questionnaire was sent through the Alumni Association of the Arabian Gulf University (AGU) to medical graduates who have valid email addresses, seeking information on their scientific productivity along with demographic and current employment data. Responses were collated and analyzed using a standard statistical software package. The chi-square test and p-value were calculated. P-value <0.05 was considered statistically significant.

Completed forms were received from 91 medical graduates. In this sample, almost a quarter of the respondents have published a research paper out of their undergraduate research project, and about 50% have published at least one paper (as main or co-author) after graduation. Both demographic and medical specialty was not related to the doctor's perception of the benefits they have attained from the compulsory undergraduate research program. However, medical graduates who are at senior levels in their medical careers and those who are employed in secondary healthcare are significantly more likely to publish research papers.

The compulsory community-oriented, project-based research program in AGU has positively contributed to the research productivity of graduates, and it would be worthwhile to include such programs as an integral part of the undergraduate medical curriculum.

The bibliography at the end of the paper contains 1,726 references to papers, conference proceedings and theses/dissertations dealing with the analysis of beams, columns, rods, bars, cables, discs, blades, shafts, membranes, plates and shells that were published in 1996‐1999.

Presents a new B‐spline finite element for the dynamic analysis of unsymmetrical sandwich shells of revolution. The formulation takes account of the membrane and bending effects in isotropic or orthotropic elastic facings, and membrane, bending and transverse shearing effects in an isotropic or othotropic elastic core. Both geometry and local displacements are interpolated by a set of B‐spline functions. The main aspects added by the sandwich structure of the element are the transverse shearing and membrane‐bending coupling effects in the core. These are well represented by a set of new variables which are the mean end relative in‐plane displacements of the facing middle surfaces. Together with the transverse displacement, these variables constitute the degrees of freedom (dofs) of this new B‐spline sandwich element. The finite elements are grouped into super‐elements with C¹ continuity to obtain the whole finite element model. For each super‐element a total of five dofs per node is then obtained except for its end nodes where the derivatives of these dofs with respect to the meridional co‐ordinate are added. This choice reduces to a minimum the total number of dofs in comparison to existing sandwich elements. Evaluates the efficiency and accuracy of the proposed element through several benchmark examples. Compares the results with the analytical and numerical solutions found in the literature. A very satisfactory behaviour of the element was observed in all test cases.

Interpersonal and informal ties and networks, known as wasta in the Arab Middle East region, remain a major force in Middle Eastern societies, determining most economic, social and political outcomes. Yet the literature on informal ties and networks is largely characterized by a lack of contributions from the Arab world, despite the adverse effect that lack of understanding of the wasta phenomenon is having on the effectiveness of expatriate managers and subsequently on business performance. This chapter therefore aims to shed light on the meaning, characteristics, structure, and role of wasta in establishing and maintaining successful business relationships. It ends with recommendations for foreign investors and international managers who wish to establish and maintain successful business relationships in the Middle East on how to capitalize on interpersonal networks within this process.

The purpose of this paper is to examine whether investors’ sentiment affects accruals anomaly across European countries.

The authors estimate the model using Fama–MacBeth regressions. The sample includes 54,572 firm-year observations for 4,787 European firms during the period 1994–2014.

The authors find that investors’ sentiment influences accruals mispricing across European countries. The effect is pronounced for stocks whose valuations are highly subjective and difficult to arbitrage. The cross-country analysis provides evidence that sentiment influences accruals anomaly in countries with weaker outside shareholder rights, lower legal enforcement, lower equity market development, higher allowance of accrual accounting and in countries where herd-like behavior and overreaction behavior are strong.

The findings suggest the generalizability of the sentiment-accruals anomaly relation in European countries characterized by different cultural values, levels of economic development and legal tradition.

The findings suggest to caution individuals investors. These investors would be wise to take into account the impact of sentiment on the performance of their portfolio. They must keep in mind that periods of high optimism are accompanied by a high level of accruals and followed by low future stock returns.

The research supplements previous American studies by showing the significance of the level of sentiment in understanding the accruals anomaly in Europe. Hence, it is important for future studies to consider investor sentiment as an important time-series determinant of the accruals anomaly, particularly for stocks that are hard to value and difficult to arbitrage.

The purpose of this study is to develop functional probiotic Labneh cheeses supplemented with broccoli florets.

Probiotic Labneh cheese was produced using broccoli florets paste at four different levels (0, 5, 10 and 15%), with Lactobacillus casei NRRL B-1922 as a probiotic strain, to evaluate its physicochemical, phenols, antioxidant activity, minerals, vitamins, textural, microbiological and sensory characteristics during storage for 15 days.

The results indicated that Labneh cheese with added broccoli paste exhibited significantly (p = 0.05) higher level of moisture, acidity, soluble nitrogen, phenols, antioxidant activity, minerals and B vitamins, and lower protein, fat, ash and pH values when compared to control Labneh cheese. Textural analysis of Labneh cheese indicated that Labneh with higher level of broccoli (15%) exhibited harder texture than others. Higher viable counts of Lactobacillus casei and Streptococcus thermophilus were detected in Labneh with broccoli paste, and the counts (107 cfu/g) were higher than the number should be present to achieve their health benefits. The most acceptable Labneh cheeses were those supplemented with 5 and 10% broccoli paste.

This study revealed broccoli florets could enhance the growth of Lactobacillus casei and Streptococcus thermophilus in the Labneh matrix, which resulted in a wider spectrum of health benefits of Labneh cheese to the consumers.

The purpose of this paper is to illustrate some methods to protect digital libraries using digital rights management (DRM) technologies and specifically the methods applied at the digital libraries of Jordan universities.

A descriptive research method has been used to examine the extent of DRM in digital libraries of universities in Jordan.

Majority of the universities in Jordan use different methods of protection including coding, identification, authenticity and digital watermark. However, methods including digital signature, digital fingerprint, copy detection systems and pay system have not been employed within Jordanian universities. The use of copyright management systems has been limited, which shows the weakness in the use of technological protection within the investigated libraries.

This study has shown contribution to the development of digital libraries that are based on the protection of new technology and are able to provide better services to users without concern about protecting publishers’ rights.

This study aims to provide empirical evidence on the role of corporate governance mechanisms in reducing earnings-management practices in Islamic banks in Asia.

This study used 28 Islamic banks in Asia, which were listed on the stock exchange from 2013–2017. The research method used quantitative regression with data on the characteristics of Islamic banks taken from the websites of each bank. This study used discretionary loan loss provision as a proxy for measuring earnings management.

The results show that only the audit committee size has a significantly negative effect on earnings management. An independent audit committee has a negative, but not significant, effect. The difference expectation signs cannot be interpreted further.

Only a few components of corporate governance were tested in this study. Therefore, it is expected that future studies will include more components.

In general, the components of corporate governance that include the characteristics of the board of directors and the audit committee have a varied effect on reducing the earnings-management practices in Islamic banks, except audit committee size. In practice, audit committee size should have an important role in earning management reduces.

This may be the first paper that studies the effect of corporate governance on earnings management in Islamic banks in Asia.

This study aims to investigate the linkage of employee treatment and trade credit for a sample of 45 countries from 2003 to 2018. It explores the trade credit from a receivable perspective.

The estimations are performed using panel regression with fixed effects for both country and year. A batter of robustness tests is also performed to validate the findings.

The results reveal a positive and highly significant relation between employee treatment and trade credit. The authors observe that firms from labor-intensive and highly competitive industries are likelier to extend trade credit to their customers. The authors also find that firms from developed countries are more likely to extend trade credit to their customers.

First, to boost trade credit, the firms need to materialize fair employee treatment. Second, firms from labor-intensive firms and highly competitive industries need to care more about employee treatment which promotes trade credit.

The findings offer novel evidence of the relationship between employee treatment and trade receivables.
