The purpose of this paper is to compute flow effects of the transition from adherence-to-slip in two-dimensional flows, for a polymer melt obeying a memory-integral viscoelastic equation, in isothermal and non-isothermal cases.

Temperature dependence is expressed by Arrhenius and William-Landel-Ferry models. A coupling approach is defined. For the dynamic equations, the Stream-Tube Method (STM) is used with finite differences in a mapped rectangular domain of the real domain, where streamlines are parallel and straight. STM avoids particle-tracking problems and allows simple formulae to evaluate stresses resulting from the constitutive equation. For the temperature field, a finite-element method is carried out to solve the energy equation in the real domain.

The approach avoids numerical problems arising with classical formulations and proves to be robust and efficient. Large elasticity levels are attained without convergence and refinement difficulties that may arise close to the “stick-slip” transition section. The method highlights the role of temperature conditions and reveals interesting differences for the ducts considered.

The results of the study are of interest for polymer processing where slip at the wall can be encountered, in relation with the physical properties of the materials.

The paper presents a simple approach that limits considerably numerical problems coming from stick-slip boundary conditions and avoids particle-tracking. Results are obtained at flow rates encountered in industrial conditions.

This study is motivated by the competing views on whether internal governance mechanisms complement or substitute for external auditing, and how this association is affected by ownership concentration. The complementary view predicts that good internal governance mechanisms are related to high-quality audit. On the other hand, corporate governance mechanisms may be substituted for each other, so more investment in governance mechanisms leads to less investment in external auditing. Therefore, this study aims to examine the association between internal governance mechanisms and the demand for audit quality.

Data from Malaysian listed companies during the period 2009 to 2012 are used. Ordinary least square (OLS) regression is applied to analyse the data.

Companies with a higher concentration of ownership are less likely to demand extensive auditing. In addition, the study provides supporting evidence for the complementary association between a company’s governance and audit fees. However, the ownership concentration plays a minor role in the positive association between internal corporate governance and audit quality. Further tests are conducted and support the main findings.

Significant implications are provided for the audit profession in emerging economies, where concentrated ownership is common, to help policymakers and regulators in determining the power of controlling shareholders on audit quality and firm’s governance. The study’s findings open up avenues for further research.

This is the first work to address the role of ownership concentration in the association between corporate governance and audit quality; it suggests that the ownership structure must be considered in examining the effectiveness of corporate governance. The study also provides a comprehensive combination of internal governance mechanisms.

This article investigates recent studies of construction law in different areas, including civil engineering; construction building technology; transportation; multidisciplinary studies and the environment, as well as their changing trends in the years between 2000 and 2019.

The transformation trend of construction law is investigated based on collecting main keywords from the Web of Science (WoS) database selectively from different viewpoints and using Scientometric Analysis by CiteSpace and HistCite software. The top journals, top universities, and the most active countries in publishing and expanding construction law, keyword co-occurrence network, top keywords with the strongest citation bursts, cluster analysis, the most cited articles are determined both generally and yearly.

By interpreting the Scientometric results, focal points of legal issues and their changing trends during the last two decades are reviewed. Scholars’ data concerning interesting topics, construction law industry future needs, knowledge gaps, and speculation about future views and direction are obtained.

Restrictions on data search, limiting the category of studies to a specific domain, and limiting research time to 20 years are some limitations of this article.

All these results address legal issues, comprehensive laws, plenary contracts, and efficient dispute resolution based on cultures and themes.

Given the importance of legal issues at all stages of the construction cycle, a review of this multidisciplinary and new science over the past two decades can provide hot issues, knowledge gaps, and a better view of the future.

This study aims to propose a national frame of reference for the accreditation of engineering programs (EPs) in Tunisia. It uses as a benchmark the structure used by the world’s leading accreditation systems such as the Accreditation Board for Engineering and Technology (ABET) and Commission des Titres d’Ingénieur. It provides a comprehensive framework for academic institutions to evaluate the performance of their programs. In addition, it suggests the procedures, steps and timeline for the application process and defines the required documents that should be submitted.

The study analyzes the standards applied by well-established accreditation agencies such as ABET, Commission Titre Ingenieur and European Accredited Engineer, studies the perceptions of academicians who participated in six workshops and uses the results of surveys and interviews to characterize their opinions about accreditation. A sample population of 146 faculty members, experts and policymakers from 23 different higher education institutions in Tunisia, who had participated in the workshops mentioned above, was solicited to participate in the survey. The opinions of 51 respondents who responded to the survey were analyzed. This methodology led to the establishment of a proposed national frame of reference for accreditation of EPs.

Analysis reveals that the Ministry of Higher Education and Scientific Research (MHESR) provides authorization (“habilitation”) to institutions allowing them to offer their educational program. However, it is inaccurate to consider this procedure as accreditation because it is more of a licensure process. In addition, the MHESR grants the “habilitation” to those institutions that successfully apply. The National Authority for Assessment, quality assurance and accreditation Instance Nationale de l’Evaluation, de l’Assurance Qualité et de l’Accréditation (IEAQA) is not involved in this process, which makes the latter’s role trivial.

This frame of reference will help the MHESR to evaluate the EPs based on a comprehensive analysis of well-established accreditation systems, to improve its “habilitation” process by splitting it into two parts as per international practice, namely, licensure and accreditation and to make the existence and role of the IEAQA much clearer.

This study is the foremost study to propose a comprehensive frame of reference for accrediting EPs in Tunisia.

The purpose of this study is to check the impact of financial development on green technological innovation (GTI).

The sample size includes the 20-year (2001–2020) financial statistics of six Gulf Cooperation Council (GCC) region countries. To check the proposed relationship, this research uses a series of econometric models including fixed effect, fully modified ordinary least square and robust least square models.

The statistical results imply that financial sector development has a direct significant impact on GTI. A developed financial sector can uplift green technological development by offering more loans to industrial sectors and the import of modern technology. The statistical analysis further reveals the positive impact of gross domestic product (GDP), foreign direct investment inflow and trade volume while the negative impact of resources contribution on GTI.

The findings suggest key policy suggestions regarding the role of the financial sector in promoting GTI in the GCC region.

The novelty of this study lies in its examination of the relationship between FD and GTI in the GCC countries, a region with its unique economic and environmental dynamics.
