It is available at: https://doi.org/10.1177/0734242X20910463.Widespread reuse of building components can promote the circularity of materials in the building sector. However, the reuse ofbuilding components is not yet a mainstream practise. Although there have been several studies on the factors affecting the reuse ofbuilding components, there is no single study that has tried to harmonize the circumstances affecting this intervention. Through asystematic literature review targeting peer-reviewed journal articles, this study intends to identify and stratify factors affecting thereuse of components of the superstructure of a building and eventually delineate correlations between these factors. Factors identifiedthroughout this study are classified into six major categories and 23 sub-categories. Then the inter-dependencies between the barriersare studied by developing the correlation indices between the sub-categories. Results indicate that addressing the economic, socialand regulatory barriers should be prioritized. Although the impact of barriers under perception, risk, compliance and market subcategoriesare very pronounced, the highest inter-dependency among the sub-categories is found between perception and risk. Itsuggests that the perception of the stakeholders about building components reuse is affected by the potential risks associated with thisintervention.Peer reviewedFinal Accepted Versio

The effect of telework on organizational commitment, case of IT Engineers Casablanca Rabat region

Research in management sciences has proposed a set of works centered on the theme of corporate social responsibility (CSR) and that of organizational behavior, but few studies focus on telework. However, research seems limited to the interaction of these two variables. The concept of telework seems relevant because it questions the organizational functioning and the role of human resources management (HRM). Giving that turnover rates is a major occupation for companies as it affects their performance, we aim to determine the viability of his usage to improve this KPI. We have selected the case of new technology companies in Morocco as a field of investigation. Our research is driven by the following question: can the perception of telework by employees have effects on their attitudes and behaviors in terms of organizational commitment? We chose Moroccan IT companies as the subject of our study s they depend greatly on human capital to ensure continuity. There is a scarcity of local talent, which drives the turnover higher. This article highlights the links of effects that connect our two variables through the analysis of 18 qualitative interviews. The results improve our understanding of the impact of telework on the behaviors and attitudes of employees in terms of organizational commitment. The exploratory nature of our research leads us to choose a qualitative methodology with a comprehensive aim. Semi-directive interviews made it possible to explore the different perceptions of employees and the resulting organizational commitment behaviors, followed by analysis for each case based on occurrences in discussed themes. The study revealed a positive correlation between teleworking and organizational commitment.     Classification JEL: O15 Paper type: Empirical researchResearch in management sciences has proposed a set of works centered on the theme of corporate social responsibility (CSR) and that of organizational behavior, but few studies focus on telework.

Impact de la culture d’entreprise sur la performance des PME au Maroc : de l’approche théorique à la réalité empirique

L’importance de la culture d’entreprise n’est plus eue démontré étant donné que son émergence a fait essor depuis les années 80, en tant que facteur permettant de fédérer l’ensemble du personnel de l’entreprise autour des valeurs communes créées par l’entreprise et pilotées par son capital humain en se basant sur une culture nationale qui met en valeur les bien-fondés de l’appartenance et de l’apprentissage collectif. Notre objectif étant de pouvoir retracer le panorama historique de cette notion à travers les différentes théories qui l’ont traité et ainsi pouvoir dégager son intérêt et son utilité à asseoir un modèle performant de gouvernance et de management des entreprises et en l’occurrence les petites et moyennes entreprises qui à travers un effectif réduit se doit de nouer une confiance forte entre l’ensemble du personnel et faire de leur capital humain la pièce maîtresse de développement de leur activité. Aussi, de relever cette corrélation entre les deux variables d’études « culture d’entreprise et performance » d’une manière empirique auprès d’un échantillon de 384 PME en s’appuyant sur la problématique suivante : Quels sont les avantages et les limites de la culture d’entreprise en tant que facteur de développement de la performance des PME 

Users Integrity Constraints in SOLAP Systems. Application in Agroforestry

SpatialData Warehouse and Spatial On-Line Analytical Processing are decision support technologies which offer the spatial and multidimensional analysis of data stored in multidimensional structure. They are aimed also at supporting geographic knowledge discovery to help decision-maker in his job related to make the appropriate decision . However, if we don’t consider data quality in the spatial hypercubes and how it is explored, it may provide unreliable results. In this paper, we propose a system for the implementation of user integrity constraints in SOLAP namely “UIC-SOLAP”. It corresponds to a methodology for guaranteeing results quality in an analytical process effectuated by different users exploiting several facts tables within the same hypercube. We integrate users Integrity Constraints (IC) by specifying visualization ICs according to their preferences and we define inter-facts ICs in this case. In order to validate our proposition, we propose the multidimensional modeling by UML profile to support constellation schema of a hypercube with several fact tables related to subjects of analysis in forestry management. Then, we propose implementation of some ICs related to users of such a system

Can securitizing public procurement contracts help small and medium-sized enterprises access capital and contribute to economic growth?

Public procurement contracts are agreements issued by government entities to acquire goods, or services, from external suppliers. These contracts typically require a significant financial investment to handle upfront costs, mobilize resources, and sustain operations throughout the contract duration. Consequently, they are often awarded to large, established firms. As a result, this creates challenges for smaller companies, as they face difficulties in competing against these larger firms. Smaller companies often have limited access to capital markets and may lack financial stability. These resource limitations place them at a disadvantage, making it challenging to compete on an equal footing with larger, more resourceful firms in the procurement arena. However, the role of small and medium-sized enterprises (SMEs) is crucial in driving economic growth and development. Recognizing the criticality of small and medium-sized companies, it is essential to cultivate an enabling environment that supports their growthand facilitates access to resources and markets. The objective of this research paper is to shed light on the feasibility of using securitization as a financing mechanism to enhance the capital accessibility of SMEs in the context of public procurement contracts. Based on a thorough review of the available literature, to date, there is a dearth of literature specifically addressing the securitization of public procurement contracts. This research paper, therefore, serves as a pioneering contribution to the field, introducing and proposing a conceptual model for the utilization of securitization as a potential financing mechanism in the context of public procurement. Drawing upon existing literature on securitization and public procurement, a theoretical conceptual model is presented, outlining the key components and potential mechanisms involved in securitizing these contracts. By venturing into unexplored territory, the paper aims to shed light on the feasibility, advantages, and challenges associated with this novel financing approach. Our analysis reveals a robust positive correlation between the securitization of public procurement contracts and the enhancement of access to capital for small and medium-sized enterprises (SMEs). Through the securitization process, SMEs can convert their expected future cash flows from public procurement contracts into tradable securities. This transformation enables SMEs to tap into the capital markets and attract a diverse range of investors interested in these securitized instruments. Consequently, we conclude that securitization of public procurement contracts emerges as a promising mechanism to empower SMEs and address their persistent challenge of limited access to capital, ultimately contributing to their overall success, competitiveness, and hence economic growth.   Key Words: Securitization, Public procurement contracts, Small and medium-sized enterprises, Financing mechanism, Capital accessibility, Economic growth, risks and challenges.

Territorial intelligence : The contribution Web 3.0 technologies in practice the territorial intelligence

The term "Territorial intelligence 3.0" refers to the usage of the web 3.0 technologies, such as the mobile web, web applications and the semantic web, in the process of Territorial intelligence. The territorial intelligence represents an offensive and a defensive attitude with all implications in terms of the information generated on global markets. The concept, the origin and the foundation of the above-mentioned term emerging in two distinct communities, one brings together practitioners of territorial intelligence developed around the institutional field, it is the case of top-down territorial intelligence. And the other community, brings together theorists searches in the multidisciplinary academic field, it comes from research on the economy, geopolitics, knowledge management and the discipline of information and communication technology sciences, this is the case of bottom-up territorial intelligence. The Web 3.0 technologies, combine, on the one hand, web 2.0 technologies; the community Web (social networks: Linked in, Twitter, Facebook, etc.) and the collaborative Web (Wikipedia and Weblogs) (Quoniam & Lucien, 2009), and, on the other hand, smartphones, the internet of objects (Internet of Things), cloud computing technology and big data. “Web 3.0 is the combination of smart phones, social networks, Web 2.0, cloud computing and emerging business models as explained above” (Russell et al., 2016), web 3.0 practitioners consider that much of the world's information being correlated and frankly opening up to the general population, combine between these two concepts: Generating the management strategic territorial information founded on Web 3.0 and working in favor of the territory. There are generally two types of territorial intelligence 3.0. The first one is the top-Down Territorial Intelligence 3.0, it’s the evolution of the national policy of competitive Intelligence 3.0 at the local level, but the term “competitive Intelligence 3.0” has been subjected to the same web evolution. And the second one is the bottom up territorial intelligence 3.0, it is manifested by the contribution of the actors of the territory in the process of local development through the technology of web 3.0. The goal of our research is to propose a conceptual model base on a theoretical in the context of territorial intelligence in a digital sphere by web 3.0 technology.
