The impact of financial development on the economic growth of selected Arab countries

Financial development has become a subject of great interest in the Arab countries. This development plays an important role in mobilizing domestic savings and directing it towards investment channels, according to its ability to employ capital on the one hand, and its linkage to market , on other hand the rise of phenomenon of assessment of foreign exchange rates and interest rates at the international level, which has often led to the absence of any obstacles to capital flows in a variety of credit tools and savings and foreign currencies ,especially that the financial development Following the economic developments and the expansion of consumer and investment spending. The research checks an effect of financial development on the economic growth in selected Arab countries (Jordan, Egypt, Algeria, Tunisia, Saudi Arabia and Bahrain) during the period 2000-2017

SEPCS: Prolonging Stability Period of Wireless Sensor Networks using Compressive Sensing

Compressive sensing (CS) is an emerging theory thatis based on the fact that a small number of linear projections of asparse data contains enough information for reconstruction. CScan break through the asymmetry between the data acquisitionand information processing that makes a great challenge to therestriction energy and computation consumption of the sensornodes. In this paper, we propose a routing protocol called SEPCSfor clustered wireless sensor networks (WSNs) using CS. SEPCScombines a new clustering strategy with CS theory for prolongingstability period and network lifetime in WSNs. Our simulationresults show that the proposed protocol can effectively prolongthe stability period and network lifetime compared with existingprotocols

Optimized Clustering Protocol for Balancing Energy in Wireless Sensor Networks

While wireless sensor networks (WSNs) are increasingly equipped to handle more complex functions and in-network processing may require these battery powered sensors to judiciously use their constrained energy to prolong the effective network lifetime. Cluster-based Hierarchical Routing Protocol using compressive sensing (CS) theory (CBHRP-CS) divides the network into several clusters, each managed by a set of CHs called a header. Each member of the header compresses the collected data using CS. This paper proposes an optimized clustering protocol using CS (OCP-CS) to improve the performance of WSNs by exploiting compressibility. In OCP-CS, each cluster is managed by a cluster head (CH). CHs are selected based on node concentration and sensor residual energy, and performs data aggregation using CS to reduce the energy consumed in the process of data sampling and transmission. Simulations show that our proposed protocol is effective in prolonging the network lifetime and supporting scalable data aggregation than existing protocols

A Literature Review on Persuasive Communication: Utilising Elaboration Likelihood Model to Understand Consumer Engagement on Social Media Platforms

The public’s consumption of social media has experienced a significant increase. This trend encourages marketers to use social media platforms to market their business and boost consumer engagement. Though studies have been conducted on the public’s consumption of social media and several theories anticipating consumer behaviour, motivation, and technological adoption have been developed, research into the relationship between marketing and promotional communications and consumers’ attitudes and choices has been limited. For example, the Elaboration Likelihood Model (ELM), which is a reasonable and viable model capable of explaining disposition and conduct in influential marketing communication, has remained unnoticed by researchers. The purpose of this study was to ascertain whether persuasive messages used in social media marketing could effectively increase consumer engagement (CE) using ELM. This research employed the search terms ‘elaboration likelihood model, consumer engagement, and social media’ on a Scopus-indexed academic database, dated from 2018 to 2023. A total of 16 articles were selected following a screening stage. The administered systematic literature review suggests that ELM provides a hypothetical direction to arranging online entertainment content angles (i.e., focal and fringe signs) and recognising the variables that influence consumer engagement. A greater understanding of how to build consumer engagement on social media platforms through ELM can give insight into developing effective strategies for marketers. Future research can use the current study to improve research on social media and consumer engagement by using and expanding ELM

Critical Analytical Insights of Palliative Care Process Modelling in a Regional Cancer Care

Palliative care services are rapidly evolving in cancer care organisations. In palliative care processes, administratives are involved without acknowledging that they may hinder rather than facilitate the path of palliative care in respect to cancer patients. Comprehending a palliative care organisation, without looking at current running processes is groundless. Therefore, a critical understanding of palliative care processes is necessary for improving respective cancer care systems. In this research palliative care Business Process Models (BPMs) have been developed to empower palliative care domain experts not only attaining a critical understanding of the currently running palliative care operations, but also in informing further required improvements with associated implications on cancer patients. Amongst the key outcomes of developing and analysing palliative BPMs in a cancer care organisation revealed identifying gaps, limitations, challenges, and opportunities to reflectively improve palliative care processes in cancer care centres. Finally, this research suggests further re-engineering of palliative care processes as reference models that may be instantiated in specific socio-cultural, person-centered, and other contextual settings aimed at improved qualitative palliative care for cancer patients

Digital Consumer Engagement: Examining the Impact of Audio and Visual Stimuli Exposure in Social Media

The promotion of coffee shops through Instagram content has become highly beneficial to consumers’ decision-making, as short videos reel Instagram and photos can help consumers judge and experience products through visual and audio stimuli on content. Consequently, scholars and managers must understand consumer behaviors regarding audio-visual stimuli on Instagram content and identify factors influencing perception and consumer engagement with content. A novel contribution of this study is the introduction of audio-visual stimuli on Instagram content based on the stimulus-organism-response paradigm, which explains how sensory marketing and information adoption affect consumer engagement on social media Instagram. To empirically evaluate the proposed research model, we conducted an online survey with 120 participants who followed Instagram @kopijanjijiwa and @kopikenangan. We performed data analysis using structural equation modelling and Smart-PLS software and the results indicated that all hypotheses, except for perceived cognitive and audio-visual stimuli, significantly affected consumer engagement. This study could provide insights into the antecedents of perceived cognitive and consumer engagement on social media Instagram. Thus, contributing knowledge of digital consumer behavior helps managers understand consumer behavior regarding social media and formulate marketing strategies

Critical Analysis of Palliative Homecare Using the i∗ Framework\u27s Strategic and Social Requirements Modelling Applied to a Cancer Care Organisation

Home Health Care (HHC) is an essential and critical part of palliative care and especially for terminal cancer patients. This research is aimed as a first attempt to align with the research gap in modelling the social requirements of palliative care processes and the HHC process in particular. Consequently, this research is a first attempt at developing an $\mathbf{i}^{\ast}$ framework visual goal-oriented and social requirements models of the HHC process of the domain of palliative care with a reflected application using a case study from a leading regional cancer centre in the Middle East, namely KHCC. Furthermore, this research has made it possible for palliative care domain experts in the HHC process and using the associated $\mathbf{i}^{\ast}$ framework strategic dependency and strategic rationale models to visually trace the most critical and strategic actors in the HHC process along with the highly interacting dependers and dependees. Finally, the HHC $\mathbf{i}^{\ast}$ strategic models contribute to bridging the gap between the world of palliative care requirements and their reflective computer-based information systems and $\mathbf{IoT}$ smart devices. Hence, this sheds light towards the realisation of the field of palliative care as being a “systems of systems” virtual organisation with the respective socio-technical systems involvement, for the best care of the palliative patient and especially terminal cancer patients. A further corollary of this research is the insufficiency and less representativeness of palliative care process models to utilise in guiding the development of the HHC $\mathbf{i}^{\ast}$ framework strategic models without linking to the full associated strategic and policy documents of palliative care

A review of biolubricants in drilling fluids: recent research, performance, and applications

Lubricant additives are added to drilling fluids to lower the drag and torque between the drill strings and rock formation. They impart lubricating properties into two moving surfaces contacts under extreme temperature and pressure conditions. Currently, there is a significant interest in developing biolubricants derived from organic sources. Biolubricants offer several valuable friction-reducing physicochemical properties, including high lubricity, wide viscosity range, low pour point, high flash point, high thermal stability, and biodegradability when applied in drilling operation. This study reviews the application of general lubricants in drilling fluids and the potential of biolubricants derived from vegetable oils in exceeding the performance of hydrocarbon and mineral-based lubricants. Overall, biolubricants possess most of the physicochemical properties required as a lubricant for drilling fluids. The utilization of organic ester-based biolubricant might result in faster and deeper drilling, lower bioaccumulation and high biodegradability characteristic, less waste volume, and reduced in overall operation cost. Among the available biolubricants, polyol esters of vegetable oils demonstrate the most suitable lubricants for many drilling conditions, even though their application is still very limited

Native/Aboriginal Students use Natural Health Products for Health Maintenance More so than Other University Students

Background and aim: University student use of Natural Health Products (NHP) for health maintenance (HealthM) is assessed in Canada. We hypothesize greater use of NHP by Native/Aboriginal and female students. Demographic predictor variables and the top ten NHP used are determined. Methods: A cross-sectional survey of 963 students (n=212 Native/Aboriginal; n=751 non-Native/Aboriginal) was conducted. χ2 and Fisher’s exact tests analyzed group differences. Multiple logistic regressions determined predictor variables of NHP use. Results: Of 963 surveyed students, 268 (27.8%) used NHP for HealthM, while 695 students (72.2%) did not. More Native/Aboriginal students used commercial tobacco (47% vs. 13%, P\u3c0.001) and NHP (67% vs. 45%, P\u3c0.001) than non- Native/Aboriginal students. Gender was not associated with NHP use (P=0.527). Canadians used echinacea more than non-Canadians (Odds Ratio [OR]=4.96; 95% Confidence Interval [CI]: 1.2-21.0). Ginger (OR=0.39; 95% CI: 0.2-0.78) and garlic (OR=0.28; 95% CI: 0.13-0.6) were popular amongst non-Canadians. Native/Aboriginal students used homeopathics (OR=39.9; 95% CI: 8.6-185.4) and rat root (OR=56.73; 95% CI: 6.91-465.8). Chamomile was less used by males (OR=0.33; 95% CI: 0.13-0.83) and used more by upperclassmen (OR=2.6 95% CI: 1.3-5.3). Conclusion: Homeopathics and rat root are popular amongst Native/Aboriginal students. Garlic and ginger are popular amongst non-Canadians than Canadian students; however, more Canadians used echinacea for HealthM than non-Canadians. Chamomile is less popular amongst males. Commercial tobacco is used more by Native/Aboriginal students. Predictors of NHP use are: Native /Aboriginal and upperclassman
