Developing an optimized project schedule that considers all decision criteria represents a challenge for project managers. The purpose of this paper is to provide a multi-objectives overall optimization model for project scheduling considering time, cost, resources, and cash flow. This development aims to overcome the limitations of optimizing each objective at once resulting of non-overall optimized schedule.

In this paper, a multi-objectives overall optimization model for project scheduling is developed using particle swarm optimization with a new evolutionary strategy based on the compromise solution of the Pareto-front. This model optimizes the most important decisions that affect a given project including: time, cost, resources, and cash flow. The study assumes each activity has different execution methods accompanied by different time, cost, cost distribution pattern, and multiple resource utilization schemes.

Applying the developed model to schedule a real-life case study project proves that the proposed model is valid in modeling real-life construction projects and gives important results for schedulers and project managers. The proposed model is expected to help construction managers and decision makers in successfully completing the project on time and reduced budget by utilizing the available information and resources.

The paper presented a novel model that has four main characteristics: it produces an optimized schedule considering time, cost, resources, and cash flow simultaneously; it incorporates a powerful particle swarm optimization technique to search for the optimum schedule; it applies multi-objectives optimization rather than single-objective and it uses a unique Pareto-compromise solution to drive the fitness calculations of the evolutionary process.

There is no doubt that the political speech of the Syrian President Bashar Al-Assad is of exceptional importance in understanding the developments of the war in Syria, and clarifies the position of all parties involved in the war, whether local, regional or international. Accordingly, and based on the dismantling of political discourse, the identification of its core, as well as its variables and major themes of this discourse, this study aims to understand the levels of complexity, paths and the fate of the war in Syria that certainly does not come free of charge, the hardest of which is the human cost whether for the victims or the displaced persons.

After a careful study of all the resilient factors in the literature review to categorize the primary data based on Assad’s discourses in the media, through a “qualitative research study” of his “interviews and discourses,” it is found that the Assad’s rhetoric is highly relevant to his tenacious presidency. The research reveals the themes that dominated Assad’s interview responses and speeches and his strategy of framing the revolution as a foreign insurgency against his government. In fact, Assad delegitimizes any semblance of the uprisings as a “pro-democracy movement” or “revolution,” denying the presence of a rebellion against his government.

By the analysis the study found out that Bashar Al-Assad continued to focus on certain reasons and issues that led to the crisis and the continuation of the war, such as the Muslim Brotherhood’s involvement, considering the Syrian opposition abroad as agents of Western countries, Syria is subject to a regional and international conspiracy, terrorism is a major scourge that must be fought and that the army is essential in resolving the battles taking place there. Likewise, emphasizing the internal dialogue with all stakeholders and involved parties is the way to solve the crisis.The Syrian President’s speeches do not focus much on the accusations against his regime from the opposition or the international parties involved in the conflict.

Assad’s resiliency has made him a distinct leader in the region. This paper analyzes the factors contributing to Assad’s resiliency. The literature review consists of the existing theories on authoritarian persistence and Assad’s power base in particular. The literature review discusses the factors that helped Assad adopts his resiliency strategies to the conflict environment. The research focuses on how Assad used the media as a platform for displaying his own manipulative narrative of the conflict. It concludes that Assad’s use of the media as his propaganda tool legitimized his rule, making it highly relevant to his persistence.

The retail landscape is dramatically changing due to a series of socio-economic and technological challenges, which can be faced through the adoption of smart technologies. Accordingly, a significant number of publications in this field have been produced, albeit with fragmented results. Therefore, this paper aims at both providing a clear and organised overview of the main smart technologies for physical retailing, in terms of application fields and expected impact, while identifying the major shortcomings and future research avenues.

The research conducts a systematic review of the literature concerning the assimilation of smart technologies within physical retail environments, resulting in the analysis of 103 papers published from 2005 to 2023. The review highlights (1) the main smart technologies employed in retail stores, (2) their application area and (3) the beneficiaries of their adoption. Accordingly, these three aspects are initially assessed independently and then examined in combination.

The analysis presents a comprehensive list of 16 key technologies (what) that can support a wide range of processes, spanning from back-end functions to front-end activities, also enabling the connection with online channels (where), catering several and different benefits (why) to both customers and retailers (who). Besides, the research points out many uncovered topics that could be addressed by the academic community.

To the best of the authors’ knowledge, the review is the first one in the literature offering a thorough and organised overview of the different available technologies for in-store application and their impact on physical retail processes.
