The persistence of inflation is considered a serious problem in developing countries because it erodes the standard of living of the majority of people. Nowadays, researchers are showing interest in energy price shocks as one of the drivers of inflation. So, the present study examines the role of pump diesel and pump gasoline prices on inflation controlling real exchange deprecation and urbanization using NARDL from 1990 to 2020. The result shows that the pump domestic diesel prices and pump domestic gasoline prices have a positively asymmetric impact on inflation in Pakistan. In contrast, real exchange deprecation and urbanization positively affect inflation. This study recommended that the government decrease the dependence on imported energy and focus on cheaper and domestic energy resources to fulfil the growing energy demand.","PeriodicalId":305127,"journal":{"name":"Spring 2023","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129500352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spirituality refers to different prospects for different people, such as believing in a higher power, inner peace, finding a higher purpose in life, and connectedness with self, others and the natural world, among others. Spirituality has a significant association with the life of human beings and is a greater source of positive deeds, which has a great concern in an individual's personal, social, physical and economic situation. Throughout the world, especially in developing countries like Pakistan, individuals living with HIV face several stressors regarding the chronicity of their diseases and experience a very high level of post-traumatic stress. In this study, researchers examined the impacts of spirituality on the health condition of HIV patients by applying quantitative research methods & techniques. Data were collected from patients registered at HIV/AIDS control centres of districts Gujrat and Sargodha. Non-random convenience sampling techniques were applied, and primary data was collected through a structured questionnaire. Advanced statistical software SPSS-21 was used for empirical and reliable results. The findings of the study indicated that spirituality has significantly positive impacts on the psycho-social and physical health conditions of HIV patients.","PeriodicalId":305127,"journal":{"name":"Spring 2023","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130108556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examining the notion of \"might is right\" prevalent in our society, we highlight the existing disparity between the Constitution's perceived strength and its practical application. By scrutinizing the principle of strict construction of laws, we explore how it poses significant threats to citizens' liberties. While stringent interpretation may appear necessary for national security and governance, it often leads to an unjust infringement upon individual rights. This study emphasizes the importance of imposing limitations on government requirements to safeguard against arbitrary deprivation of liberty. By advocating for due care, caution, and attention in the decision-making process, we aim to foster a more balanced approach that respects citizens' fundamental rights while ensuring effective governance. Through an in-depth analysis of relevant legal precedents, we propose alternative strategies and reforms that can mitigate the existing shortcomings in upholding constitutional liberties, promoting a society where justice and freedom prevail.","PeriodicalId":305127,"journal":{"name":"Spring 2023","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125461564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the impact of the digital divide on students' access to technology and its influence on their educational outcomes. A quantitative research methodology was employed, with a sample size of 400 students from diverse educational backgrounds. The study utilized survey questionnaires to gather data on internet access, device ownership, and technology use in education. The findings revealed variations in internet access across different age groups, with younger individuals having higher levels of access compared to older age groups. Additionally, disparities in household internet access were observed between rural and urban areas, with rural areas experiencing lower connectivity. Gender-based differences in personal device ownership were also evident, highlighting potential gender-related digital divides. Moreover, students from low-income households faced lower levels of internet access, indicating a socioeconomic divide in technology access. Additionally, the study emphasizes the importance of establishing technology resource centers in schools and fostering public-private partnerships to bridge the technology gap in education. The study contributes to the existing body of knowledge by providing insights into the digital divide and offering recommendations for addressing this issue in the field of education.","PeriodicalId":305127,"journal":{"name":"Spring 2023","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121324077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For better understanding of the mechanism, Positive Emotions (PE) is added as potential mediator between the relationship of psychological capital (PsyCap) and work engagement. Also, the moderating role of emotional intelligence is studied. A total of 370 registered nurses working in tertiary public and private hospitals of Lahore participated in the survey. Using convenience sampling technique, the data were collected through a standardized and structured questionnaire using cross-sectional time frame. Results revealed that PE partially mediated the relationship between PsyCap and work engagement. Moderation revealed a statistically significant moderation of EI between PsyCap and PE. Also, it was worth noting that mediating effect of positive emotions among psychological capital and work engagement was moderated by emotional intelligence at all three levels of moderation. Workplace interventions need to be developed and implemented to increase the psychological capital and work engagement of registered nurses. Findings from this research have implications for registered nurses and hospital management as well as the literature of positive psychology. The results underlined the vital role of sub dimensions of PsyCap, EI and PE in developing work engagement among registered nurses.","PeriodicalId":305127,"journal":{"name":"Spring 2023","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125310285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through an analysis of the poem, this paper explores Iqbal's perspective on the role of governance in promoting social justice and the importance of acknowledging the supremacy of Allah in shaping political systems. The poem presents a hypothetical scenario in which the devil, Iblees, convenes a council of advisors to discuss the best way to govern humanity. Iqbal uses this metaphor to critique the prevailing political systems of his time and argue for a system based on Islamic principles that prioritize justice and equality for all. Iqbal's poem highlights the need for leaders to be guided by a moral compass that reflects the values of Allah. He suggests that the pursuit of power and wealth at the expense of the poor and marginalized is antithetical to the sovereignty of Allah and will ultimately lead to societal collapse. Overall, this paper concludes that Iqbal's poem offers a compelling critique of contemporary socioeconomic political systems and provides a blueprint for a more just and equitable society based on the principles of Islamic governance.","PeriodicalId":305127,"journal":{"name":"Spring 2023","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132221909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, South Asia again became a ‘land of desire’ for Washington to consolidate its preponderance in the strategically vital region of Asia. The research, therefore, delves into a decade long post-cold war security environment of South Asia by analyzing the US policies towards India and Pakistan.
