This paper aims to study qualitative properties and approximate solutions of a thermostat dynamics system with three-point boundary value conditions involving a nonsingular kernel operator which is called Atangana-Baleanu-Caputo (ABC) derivative for the first time. The results of the existence and uniqueness of the solution for such a system are investigated with minimum hypotheses by employing Banach and Schauder's fixed point theorems. Furthermore, Ulam-Hyers (UH) stability, Ulam-Hyers-Rassias UHR stability and their generalizations are discussed by using some topics concerning the nonlinear functional analysis. An efficiency of Adomian decomposition method (ADM) is established in order to estimate approximate solutions of our problem and convergence theorem is proved. Finally, four examples are exhibited to illustrate the validity of the theoretical and numerical results.

In this paper, we study a Cauchy-type problem for Hilfer fractional integrodifferential equations with boundary conditions. The existence of solutions for the given problem is proved by applying measure of noncompactness technique in an abstract weighted space. Moreover, we use generalized Gronwall inequality with singularity to establish continuous dependence and uniqueness of ϵ-approximate solutions.

The purpose of this paper is to develop strategies of re-imaging the Rosetta historic district through choosing the suitable uses and their specific locations in compliance with the urban design fabric of the historic core. These strategies are to be fulfilled using Space Syntax as an urban analysis tool, in the context of “connectivity analysis.”

The research methodology follows the combined strategy between three methods of research: a SWOT analysis, to reveal the historic core status; an experimental research approach, which stimulates the chosen area via Space Syntax; and the third is a case study of the Rosetta historic core.

The re-usage of the Rosetta old core was not originally planned as commercial and to host movable vendors, but the core was forced to adapt afterwards to suit this usage, while the Souk and those big new residential building urban blocks have clearly deformed the historic image of the Rosetta historic core. Moving from one space to another, it was found that well-connected spaces have higher movement density, such as Al Souk Street, while less dense spaces can tolerate more movement without conflicting with highly dense ones. The existing commercial activities can be classified into movable activities – which can be easily relocated – and shop-based, which need a developmental approach in their original locations. The disconnected district can be used as a commercial zone for the movable vendors, to which human flow can be successfully directed in order to reduce the density in the more connected spaces.

The research value lies in exploring how to re-image urban heritage via relocating the places reused with unsuitable activities through Space Syntax.

Community detection is a key factor in analyzing the structural features of complex networks. However, traditional dynamic community detection methods often fail to effectively solve the problems of deep network information loss and computational complexity in hyperbolic space. To address this challenge, a hyperbolic space-based dynamic graph neural network community detection model (HSDCDM) is proposed.

HSDCDM first projects the node features into the hyperbolic space and then utilizes the hyperbolic graph convolution module on the Poincaré and Lorentz models to realize feature fusion and information transfer. In addition, the parallel optimized temporal memory module ensures fast and accurate capture of time domain information over extended periods. Finally, the community clustering module divides the community structure by combining the node characteristics of the space domain and the time domain. To evaluate the performance of HSDCDM, experiments are conducted on both artificial and real datasets.

Experimental results on complex networks demonstrate that HSDCDM significantly enhances the quality of community detection in hierarchical networks. It shows an average improvement of 7.29% in NMI and a 9.07% increase in ARI across datasets compared to traditional methods. For complex networks with non-Euclidean geometric structures, the HSDCDM model incorporating hyperbolic geometry can better handle the discontinuity of the metric space, provides a more compact embedding that preserves the data structure, and offers advantages over methods based on Euclidean geometry methods.

This model aggregates the potential information of nodes in space through manifold-preserving distribution mapping and hyperbolic graph topology modules. Moreover, it optimizes the Simple Recurrent Unit (SRU) on the hyperbolic space Lorentz model to effectively extract time series data in hyperbolic space, thereby enhancing computing efficiency by eliminating the reliance on tangent space.

This study aims to look at the effects of the Israeli occupation on the mental health of Palestinians and examine the link between political oppression and the occurrence of mental health disorders. It argues that, as human rights violations in Palestine are connected to psychological distress, the root causes of social suffering need to be considered in order not to pathologize Palestinians. The purpose of this paper lies in connecting the mental health discourse with a human rights approach to better understand this connection within the context of political violence.

The paper presents the viewpoint and perspectives of the authors on significant mental health issues in Palestine. The methodology is based on a literature review of the de-politicization of the mental health discourse and on the theoretical framework of a human rights approach. At the base of this discourse lies the demand for social justice and professional solidarity.

The study highlights that to truly understand social suffering in Palestine, it needs to be related to the prevalence of human rights violations, which in turn have a conceivable impact on the mental health well-being of individuals. It advocates for a shift from a de-contextualized, de-politicized and individualistic approach to mental health to acknowledging the importance of the social and political context in which trauma develops. It further illustrates how the adaptation of a human rights approach can strengthen demands of social justice and oppose the victimization of Palestinians.

The value of the works lies in putting the prevalence of mental health disorders in Palestine in relation to human rights violations as a consequence of the ongoing Israeli occupation and in highlighting the role that international organizations play in the de-politicization of the mental health discourse.

This paper aims to provide an assessment of the quality of management practices and implementation in hospitals operating in the West Bank of Palestine using the Malcolm Baldrige National Quality Award (MBNQA) Criteria.

Based on the MBNQA Criteria, a survey of 51 hospitals was conducted using questionnaires, interviews and focus groups to gather data. Data were analyzed and compared across all administrative types of hospitals using the MBNQA points system.

The results show that the performance of non-governmental organizations and private hospitals was superior with respect to all other administrative types. A closer look at the results show that all hospitals exhibit areas of concern such as human resource focus, information and analysis, as well as performance results.

Despite the exclusion of hospitals operating in the Gaza Strip, this research promotes critical management practices aimed at improving quality of management practices and their subsequent implementation in the surveyed hospitals.

The MBNQA Criteria, as well as other quality assessment tools, can be used to measure the various activities of hospitals and identify competencies and weaknesses in a tangible manner to improve hospital performance.

This paper presents a fresh perspective on the quality management issues in Palestinian hospitals to practitioners, administrators and academics using the MBNQA Criteria. Also, it serves as a foundation for future initiatives and programs aimed at improving quality in hospitals.

The purpose of this paper is to examine the extent of total quality management (TQM) practices implemented in Palestinian hospitals and their relationship to organizational performance using the Malcolm Baldrige National Quality Award criteria.

A survey of 51 hospitals operating in the West Bank of Palestine was conducted in order to test the validity and reliability of TQM constructs and their relationship to organizational performance.

The results showed that TQM constructs used in this study are positively related to hospital performance and for the most part the relationship was significant; they were capable of explaining a significant portion of variance in performance. Three elements were found to be strongly significant predictors of performance- people management, process management, and information and analysis.

Although hospitals operating in the Gaza Strip were excluded from the study, this research promotes critical management practices that help channeling organization resources into areas aimed at improving quality and performance.

The study showed that there are certain areas where administrators or managers need to focus on should they aspire for better performance. The constructs used in this study can be used to assess the implementation of quality practices and highlight areas for movement.

This paper provided practitioners, administrators, and academics with a fresh perspective on quality management practices and their impact on organizational performance. It also served as a foundation for future initiatives and programs aimed at improving quality in hospitals.

The purpose of this paper is to assess the level of total quality management (TQM) implementation in Palestinian governmental and non-governmental hospitals using the Malcolm Baldrige National Quality Award (MBNQA) framework.

The study is based on collecting data using a survey questionnaire that was designed according to the MBNQA criteria. In total, 363 questionnaires from governmental and non-governmental hospitals operating in Gaza Strip were analyzed to assess the level of TQM implementation level in all hospitals (governmental and non-governmental).

The main results of this study indicate that Palestinian hospitals operating in Gaza Strip perform at a relatively acceptable level. Comparing results shows that the performance of non-governmental hospitals is better with higher degree of TQM implementation than the governmental hospitals. Detailed analysis identifies improvement opportunities-related specific aspects of the human resources focus and the performance results.

Although this study has collected data from one Palestinian Territory, the Gaza Strip, it still identifies the critical factors and practices for TQM implementation within the Palestinian healthcare organizations to improve performance.

This paper suggests that business excellence models such as the MBNQA criteria can be used to assess the level of implementation of quality practices and identify the strengths and weaknesses to improve the quality of service delivery, processes, and performance of hospitals.

Despite the widespread use of TQM in the developed countries, little attention has been placed to implement and assess the quality initiatives by organizations in the developing countries and even fewer in low-income Arab countries (Aamer et al., 2017; Øvretveit and Al Serouri, 2006). In addition, a very few number of studies in reference to the assessment of TQM implementation in the Palestinian context, in general, and in healthcare organizations, in particular, highlight the need for this study. To move the field in that direction, the goal of this research was to assess the level of TQM implementation in the healthcare organizations (mainly hospitals) in Gaza Strip (one of the least fortunate areas of the Palestinian-occupied territories) where no prior similar research studies could be found. Therefore, this study contributes to filling this gap in the literature by providing empirical assessment of TQM level of implementation in Gaza Strip hospitals.
