Construction projects are complex projects taking place in dynamic environments, which necessitates accounting for different uncertainties during the planning stage. There is a significant lack of management tools for repetitive projects accounting for uncertainties in the construction environment. The purpose of this paper is to present an algorithm for the optimized scheduling of repetitive construction projects under uncertainty.

Fuzzy set theory is utilized to model uncertainties associated with various input parameters. The developed algorithm has two main components: optimization component and buffering component. The optimization component presents a dynamic programming approach that processes fuzzy numbers. The buffering component converts the optimized fuzzy schedule into a deterministic schedule and inserts time buffers to protect the schedule against anticipated delays. Agreement Index (AI) is used to capture the user’s desired level of confidence in the produced schedule while sizing buffers. The algorithm is capable of optimizing for cost or time objectives. An example project drawn from literature is analysed to demonstrate the capabilities of the developed algorithm and to allow comparison of results to those previously generated.

Testing the algorithm revealed several findings. Fuzzy numbers can be utilized to capture uncertainty in various inputs without the need for historical data. The modified algorithm is capable of optimizing schedules, for different objectives, under uncertainty. Finally AI can be used to capture users’ desired confidence in the final schedule.

Project planners can utilize this algorithm to optimize repetitive projects schedules, while modelling uncertainty in different input parameters, without the need for relevant historical data.

While there is an established body of literature that discusses the importance of stakeholder management, and also the need for involvement of all stakeholders so that all values of a heritage site can be captured in a heritage management plan, the concepts are not generally developed in ways that make them useful in practice. This research seeks to bring greater clarity to the practice of stakeholder engagement in built heritage, so that organisations can manage their stakeholders in ways that meet their strategic goals. This study proposes a novel method to identify stakeholders, a stakeholder preference mapping approach, which will depict their influence on decisions based on a of power-interest scale.

This research posits a stakeholder preference mapping approach. Virtual Stakeholder Groups (VSG) were identified and stakeholder's significance impacts were measured using the RIBA Plan of Work 2013 to determine in-depth consideration of each stakeholder's power and interest against differing stages of a heritage project. Participants were convened through a 5-day workshop, consisting of 20 Malaysian and 19 international participants (80% academics and 20% Malaysian civil servants). The Multi-Attribute Decision Analysis (MADA) technique was then used to demonstrate how stakeholder identification and analysis can be used to help heritage teams meet their mandates.

The research identified eight virtual VSG (Extremist, Expert, Economic, Social, Governance and Tourists) and their scale of power-interest influence at different stages of the heritage management process. The findings reveal varying levels of engagement from each of the different groups of stakeholders at each work stage – with Stage 5 (Construction) being the least engaged.

It is anticipated that through stakeholder preference mapping, heritage teams can increase the robustness of their strategies by identifying and effectively managing the important concepts; heritage teams can effectively manage the interface between the many (often competing) demands of differing stakeholders. Using Georgetown as a case study, the research team were able to delineate the interaction and interplay between the various stakeholders in the complex decision-making processes for a UNESCO heritage site. Applying the RIBA 2013 Plan of Work as a framework to the heritage management process enables a formalised mapping approach to the process.

Ranking and grading of architectural heritage (AH) are common for the conservation process. Decision-makers are often intuitively made decisions for the selection of the AH. However, on many occasions, these decisions are not transparent and sometimes focused only on a few aspects of the AH.

A transparent and robust methodology must be adopted to select and manage AH for the present and future generations. Selecting the list of parameters that are affecting the AH, and assessing their significance can strengthen the holistic assessment. From the literature, parameters and dimensions are identified for the evaluation of AH and its application for Odishan temple architecture (OTA). For minimizing biasedness associated with assessment, the research considered the opinion of experts, researchers and various stakeholders. For objective decision-making, the Delphi, the analytical hierarchy process (AHP) and the technique for order preference by similarity to ideal solutions (TOPSIS) methods were adopted.

Later, by observing the dimension-wise ranks and comparing the obtained grading of OTA with the existing state of protection, it was found that some temples, though having higher values with distinct dimension, lack significantly in other dimensions. However, for unbiased evaluation, all the possible dimensions should be considered. This methodology will also be useful for other decision-making processes concerning the same.

This research is limited to the OTA. However, this methodology can be adopted by changing the definitions of the parameters according to the contextual needs.

This methodology may be helpful for the further policy-making process for the conservation and management of such AH.

To date, OTA is not graded through such a methodology. Also, limited studies are found in similar line worldwide.

This research presents a comparative perception study towards rejuvenated, community-driven shophouses in George Town, Penang.

It captures the opinions of two distinct age groups by utilizing a mixed-methods approach encompassing quantitative (main) and qualitative (supporting) research to obtain a dynamic understanding of perceptions between younger and older residents in the city and how these impact the long-term sustainability of heritage conservation efforts. The distribution of questionnaires to residents of Penang was the primary data collection method, with the structure of the questionnaires supported by recent academic literature and past perceptional research studies about built heritage.

The four main findings from the study are therefore as follows: 1. Both age groups have a similar, positive perception towards the tangible, physical elements of rejuvenated shophouses. 2. Intangible, functional factors play an equal or stronger role in influencing people and their attitude towards public participation and overall “Sense of Place”. 3. The pessimistic “Sense of Place” responses from the “Older” group reflect an equally pessimistic attitude towards intangible, functional factors surrounding rejuvenated shophouses. 4. Youth-led changes to George Town's heritage shophouses are degrading the “sense of place” connecting the older generation to the city.

The study can serve as a guide for the development of more inclusive and socially sustainable conservation and adaptive re-use policies for safeguarding the heritage identity and value of shophouses for current and future generations to experience in a post-COVID world.

The handicraft industry has been contracting in recent times because of external competition and a preference for foreign-made crafts by consumers. Kiliim,¹ an Egyptian social enterprise and lifestyle brand, has initiated the process of revival needed in the industry with modern designs of the traditional crafts (local bed covers, curtains, bedding, rugs, bathmats, cushion, throw pillows dining and living cloths). This case provides an analysis of the company, beginning with how the idea of the kilim product was conceived and the dilemma they are currently facing. Although Kiliim, with various kilim product offerings, has made significant inroads in the consumer market, it must continue to adopt innovative strategies to sustain its survival in the market. With globalisation rapidly changing the dynamics of market entry and penetration, indigenous organisations must be innovative with their product and service offerings. Suggestions are made for the sustainability of the indigenous craft industry in Egypt and Africa.

This study aimed to measure the effects of the Russian–Ukrainian war on the value of imports and the food trade balance in Saudi Arabia.

Estimating the suggested model using econometric analysis for the years 1990–2021.

The amount of deficit increased in the food trade balance from 11.58 billion riyals in 1990 to 72.98 billion riyals in 2021. As for the increase in the index of food production by 10%, it leads to a decrease in the value of food imports for Saudi Arabia by 1.88%. Also, the value of the deficit in Saudi Arabia's food trade balance decreases by 5.24% as a result of a 10% rise in food exports to the country.

In light of the increase in the food price index to 145.8, the value of food imports and the deficit in the food trade balance exceed their counterparts in the current situation for the year 2021, at a rate of 37.1% and 44.5% for each respectively. In view of achieving huge financial surpluses as a result of the rise in oil prices, the Saudi Arabia is able to bear the high import bill and the amount of food trade balance deficit. Finally, the Russian–Ukrainian war leads to an increase in the cost of obtaining food commodities and their unavailability in the markets and thus affects the food security environment. Therefore, this study recommends the necessity of conducting more studies on the impact of the war on the food security of the Kingdom of Saudi Arabia.

The complex interaction between the gut flora and central nervous systems made probiotics one promising natural candidate for the management and treatment of depression. Hence, the purpose of this paper was to assess the knowledge, patterns of consumption and attitudes of patients with depression toward probiotics.

In this cross-sectional study, and through simple random sampling, 200 adults who were diagnosed with various depressive symptoms were selected. A link to a self-reported survey was sent to them with the aim of collecting sociodemographic data, assessing participants’ attitudes and knowledge toward probiotic consumption, and measuring their depression status via the Patient Health Questionnaire (PHQ-9).

A total of 164 participants (82%) provided usable responses. Approximately 55% of participants had moderate depression (PHQ-9). Participants (22.6%) tend to comply with their psychiatrists’ advice regarding probiotics more than other health specialists’ advice (p = 0.04). Only 59 (36%) had knowledge about probiotics and believed that probiotics should be consumed regularly and not only after an antibiotic course. However, many tended to follow marketing tricks and were willing to buy the most expensive and advertised probiotic products. Participants showed some differences in their attitude and knowledge toward probiotics according to symptoms severity; however, the differences were insignificant (p = 0.88).

To the best of the authors’ knowledge, this study is believed to be the first investigation assessing the probiotics’ knowledge, patterns of consumption and attitude of patients with various depression symptoms in Bahrain. The findings of this study may help improve the well-being of depressive patients by addressing the probiotic knowledge gap among them, expand the market of probiotics and enrich nutritional psychiatry literature.

The purpose of this paper is to examine the effects of the current global crisis on the integration and co‐movements of selected stock index futures markets.

Time series techniques of cointegration and weekly data covering the period from January 2001 to December 2009 were used in this study. The period of analysis was divided into two periods, namely the pre‐crisis period (January 2001‐July 2007) and during crisis period (August 2007‐December 2009).

No evidence was found of cointegration among the stock index futures markets in both periods. Accordingly, the 2007 subprime crisis does not seem to affect the long‐run co‐movements among the stock index futures markets.

The stock index futures markets provide opportunity for the potential benefits from international portfolio diversification and hedging strategies even after the subprime crisis. The stock index futures significantly extended the variety of investment and risk management strategies available to investors.

Examining the effects of the US subprime crisis on the stock index futures markets integration, to the best of the authors' knowledge, goes clearly beyond the existing literature on the subject matter.

The purpose of this paper is to examine the effects of the current global crisis on the integration and co‐movements of selected Islamic stock markets.

Time series techniques of cointegration were used over the period spanning from February 15, 2006 to December 31, 2008. In order to explore changes in the stock market integration and co‐movement, following Majid and Kassim, we divide the period of analysis into two periods, namely the pre‐crisis period (February 15, 2006‐July 25, 2007) and during crisis period (July 26, 2007‐December 31, 2008).

No evidence was found of cointegration among the Islamic stock markets in both periods. Accordingly, the 2007 subprime crisis does not seem to affect the long‐run co‐movements among the Islamic stock markets.

The Islamic stock markets provide opportunity for the potential benefits from international portfolio diversification, even after the subprime crisis. The prohibition of riba, gharar and maysir is one of the plausible reasons of no cointegration in the Islamic stock markets.

Using the Islamic stock indices, to the best of the authors' knowledge, goes clearly beyond the existing literature on the subject matter.
