يقدم المؤلف في هذا المقال، بمناسبة الذكرى الخمسين لوفاة المستعـرب الإسباني ميغيل أسين بلاثيوس عرضًا لإسهامات هذا الأخير في تاريخ الفلسفة الإسلامية، خصوصا الفلسفة بالأندلس من خلال تحليل موجز لكتاباته الئاساسية.

Series of great Islamic buildings has been built by Sultan Baybars (1260-1277). His mosque in Cairo is an example of the magnificent Mamluks architecture. This mosque follows the design of traditional mosques, with an open courtyard surrounded by four porticos, the Qibla portico is the largest one. Recently, many of the monuments of Cairo suffer from damages and deterioration according to groundwater. Due to many physical and chemical effects, a valuable historic mosque stone faced serious damage. The rising groundwater due to the overloading of the subterranean hydraulic and sewage systems. Also, the urban crawling has become a universal problem in the developing countries like Egypt. Nowadays; the new technology e.g., remote sensing techniques play an important role in cultural heritage management. The hydrological analysis and satellite data interpretation alongside the historical and survey archaeological studies are important applications in studying the cultural heritage management. This study deals with the band indices, changed detection, and spatial characterization over times. The environmental changes will detect using satellite Images indices in Multispectral Scanner System (MSS), Thematic Mapper (TM) imagery, and Sentinel 2-A. The past and current urban will extract using consolidated remote sensing and GIS techniques. Finally, the integration between the remote sensing and GIS techniques will help us to create some of the models to protect the archaeological site.

In this paper, the environmental risks and their effects on preservation issues are investigated for the archaeological area at Rosetta (Rashid “North of Egypt”), where the most famous Islamic monuments are located. The history of Rosetta is passed over different periods of historical value according to the political and economic situations. The main problem that faces the historic buildings of Rosetta is the salt coming from the soil moisture, caused by saltwater intrusion from the Mediterranean Sea. Over the past twenty years, the Ottoman buildings became the subject of many restoration tasks but most of them have been re-damaged due to the increasing level of the groundwater and humidity. Multi-temporal Satellite images have been used to detect all the changes mainly linked to the expansion of urban, water, and agriculture areas. This unplanned change in land use strongly caused witnessed disturbance in the levels of groundwater which, in turn (and along with changes in temperature), caused the deterioration process affecting the Qayitbay castle. Innovative solutions are created to support the preservation of the castle using GIS and remote sensing techniques.

The problem of the relationship between the company and the natural environment is presented in the literature as a controversial field, some researchers have not stopped accumulating arguments to prove a positive relationship between the integration of the environment and the company's performance, while others confirm the traditional approach, which considers pollution as a negative externality, the consideration of which has a negative impact on the company's performance. This debate has legitimized the emergence of entrepreneurial design to help overcome the current theoretical controversies, showing that the integration of the natural environment is a risky business, whose results are uncertain, which requires an entrepreneurial process. In this sense we have built our research object to extend the concept of green entrepreneurship to overcome some limitations of the existing theoretical framework. The entrepreneurial conception of the natural environment has allowed us to propose a continuum that illustrates the different levels of integration of the natural environment through the company's ability to trigger and succeed in a green entrepreneurial process.

Today, with the growing awareness of the corporate world of social, environmental and societal issues, a need for accompaniment is being expressed more and more. Yet, there is little academic theorization about how these advisers intervene, or need to intervene. And when it exists, it considers companies as a homogeneous whole, and even those who realize the heterogeneity of the business world, it is satisfied with the distinction based on size: large company, SME. However, to our knowledge, rare, even non-existent, are the work that call the accompanying persons to integrate in their approach to accompany the particularism of family businesses. In this sense, our objective in this paper is to provide some recommendations that we deem necessary in any intervention of accompaniment in CSR approach in the context of family businesses.

Since the publication of the Brundtland report "Our Common Future" in 1987, researchers in management sciences, particularly those in the business and society field, wanted to propose conceptions reconciling the environment, the social and the company performance. Therefore, the theoretical and empirical researches were much oriented towards promoting the idea of a possible convergence between the three dimensions of sustainable development. The stakeholder theory through its normative and instrumental dimensions was in the most this work the theoretical "shelter" to legitimate and defend this thesis. However, unlike displayed wishes, sustainability complexity emerges and imposes itself progressively. Especially after the year 2010, empirical researches recognize, increasingly, the existence of contradictions, tensions and paradox related to the corporate sustainability. This paradoxical aspect of sustainability is usually hidden in the line of traditional research. A position that needs to be revisited. In our view, this position is explained by the extensive researchers use of the stakeholder theory, the foundations of which are silent, or at least do not adequately treat the obvious opposition of the interests of stakeholders. To help fill this gap, this theoretical communication, is part of a conceptual movement "paradoxical" already underway and proposes a conceptual shift to the paradox theory as a promising new theoretical perspective for understanding the corporate sustainability. By relying on the limits of the conceptual framework provided by the stakeholder theory.
