Reports on one part of a study which investigates selected aspects of the export behaviour and assistance requirements of Saudi Arabian exporters of non‐oil products; specifically, it focuses on results concerning firms’ perceived obstacles to exporting. Provides a contribution to the literature since, although a body of knowledge exists on the area of obstacles to exporting, empirical data has tended to relate to developed countries; indeed, the limited number of studies in developing countries have tended to avoid the case of Saudi Arabia. Using MANCOVA to analyse responses to a postal survey, findings are presented which establish that a limited number of statistical differences exist between both firms with either a low or high export involvement (export ratio) and various sizes of firms. Implications for policy makers within the respective government departments and associated organisations are discussed in relation to the way in which assistance might be more effectively provided for Saudi‐Arabian firms in order to address common obstacles to exporting.

This paper aims to know the legal nature of the court’s discretionary power in business contract revocation.

Following the normative method that analyzes legislation using secondary data consisting of primary, secondary and tertiary legal materials, this research was conducted during the period November, 2023 – February, 2024. Moreover, studies that addressed the legal nature of the court’s discretionary power in business contract revocation and published since 2000 were included. The focus was made upon the business contract’s retroactive effect in relation to the Court’s discretionary power.

From the initial 312 studies reviewed, 20 met the inclusion criteria. The business contract's retroactive effect in relation to the Court’s discretionary power has been considered by the relatively small number of studies included in the review. Researchers from different countries explored the phenomenon, using different approaches to explore the topic. However, none of these researchers has examined the phenomenon in the Jordanian Context.

This research is unique, as it examines the legal nature of the court’s discretionary power in business contract revocation, which has not been investigated in the Jordanian context. The previous researches on business contract revocation have addressed laws other than the Jordanian law.

This research will be a guide for the Jordanian legislation to draft a business contract law that regulates the court's interference in cases of business contract revocation and clearly specify its role in this regard.

This research will increase the Jordanian people's awareness of the legal nature of court in cases of business contract revocation. Moreover, it will make them familiar with the current laws so that they will legally deal with cases of this kind.

It is very important to conduct this research to review the papers and laws related to business contract revocation in Jordan since this issue has not been investigated.

This study aims to predict the volume changes and collapse potential (CP) associated with the changes in soil suction by using the pressure cell and the effect of initial load on soil suction. Three types of gypseous soils have been experimented in this study, sandy gypseous soil from different parts of Iraq. A series of collapse tests were carried out using the oedometer device [single oedometer test (SOT) and double oedometer test (DOT)]. In addition, large-scale model with soil dimensions 700 × 700 × 600 mm was used to show the effect of water content changes in different relations (collapse with time, stress with time, suction with time, etc.).

A series of collapse tests were carried out using the oedometer device (SOT and DOT). In addition, a large-scale model with soil dimensions 700 × 700 × 600 mm was used to show the effect of water content changes in different relations (collapse with time, stress with time, suction with time, etc.).

The CP increases with the increasing of the void ratio for each soil. For each soil, the CP decreased when the initial degree of saturation increased. Kerbala soil with gypsum content (30%) revealed collapse value higher than Tikrit soil with gypsum content (55%) under the same initial conditions of water content and density, this is because the higher the Cu value of Kerbala soil is, the more well-graded the soil will be. Upon wetting, the smaller particles or fractions of the well-graded soil tend to fill in the existing voids, resulting in a lower void ratio as compared to the poorly graded one. Consequently, soils with high Cu value tend to collapse more than poorly graded ones. The compressibility of the soil is low when loaded under unsaturated condition, the CP for samples tested in the DOTs under stress level 800 kPa are greater than those obtained from collapse test at a stress level of 200 kPa.

The initial value of suction for all soils increases with initial water content decreases.

This study aims to investigate the strategic priorities of green building projects and analyze energy consumption alternatives in green residence projects using two innovative methods.

This study uses two methods, decision-making trial and evaluation laboratory (DEMATEL) to measure strategic priorities and golden-cut quantum spherical fuzzy technique for order preference by similarity to the ideal solution (TOPSIS) to analyze energy consumption alternatives.

The study reveals that sustainability and atmosphere are the most significant factors in determining the priorities of green residence projects, whereas innovation has a limited impact on addressing environmental challenges in the building sector. The ranking of energy use alternatives shows that sustainability issues and atmosphere quality of space heating and cooking are the top priorities, whereas other factors like white goods, water heating, lighting and space cooling are ranked lower.

This paper offers a significant contribution to the understanding of green buildings by introducing innovative methodological approaches. Theoretically, it uses the DEMATEL to enhance traditional analytical frameworks, marking a novel effort in understanding green residence projects. In addition, the golden-cut quantum spherical fuzzy TOPSIS method is introduced, offering a comprehensive decision-making framework for green projects, considering factors like energy consumption and economic feasibility. This combination of methodologies provides a holistic evaluation, emphasizing sustainability in green building construction. This study reveals untapped potential for environmental sustainability and energy efficiency, enriching the existing knowledge base.
