Models of Collapsing and Expanding Anisotropic Gravitating Source in f(R,T)f(R,T) Theory of Gravity

In this paper, we have formulated the exact solutions of the non-static anisotropic gravitating source in $f(R,T)$ gravity which may lead to expansion and collapse. By assuming the no thermal conduction in gravitating source, we have determine parametric solutions in $f(R,T)$ gravity with non-static spherical geometry filled with anisotropic fluid. We have examined the range of parameter for which expansion scalar become negative and positive leading to collapse and expansion, respectively. Further, using the definition of mass function the condition for the trapped surface have been explored and it has been investigated there exists a single horizon in this case. The impact of coupling parameter $\lambda$ has been discussed in detail in both cases. For the various values of coupling parameter $\lambda$, we have plotted energy density, anisotropic pressure and anisotropic parameter in case of collapse and expansion. The physical significance of the graphs has been explained in detail.Comment: 18 Pages, 8 Figures, Accepted for Publication in European Physical Journal

Social infrastructure and productivity of manufacturing firms - evidence from Pakistan

Does investment in social infrastructure affect the productivity of manufacturing firms in developing countries? To test this question, I empirically investigate the impact of social infrastructure indicators at district level on firm productivity using firm level data from Pakistan. I split my sample into rural and urban regions to capture the effect of regional disparities in investment in social goods while controlling for a potential selection bias from firms‟ decision to locate in regions with better infrastructure equipment. My findings reveal that indicators of health and education are positively and significantly related to firm level productivity in manufacturing industries in Pakistan. However, these results hold for urban districts only. For rural regions, both health and education show a negative impact on firm productivity

Risk Mitigation Strategies in Innovative Projects

This chapter discusses the challenge imposed by the dispersed innovation that shifts toward replicating the positive traits of co-location and coupling it with the unique advantages of the global initiative. Key concepts in this chapter include project risk, risk pertinent to the innovative projects, importance of risk mitigation in innovative projects, different risk categorization involved in mitigating risk in innovative projects, risk mitigation planning, risk mitigation strategies in innovative projects, and risk evaluation and mitigation strategies (REMS) in various types of innovative projects including the lesson learnt from the innovative projects to handle project risk by adopting risk mitigation strategies

Hesitancy In Getting COVID-19 Vaccine – An Alarming Concern

According to new research, health care workers and medical students are reluctant to receive vaccinations. This recent research found that hesitancy was often observed in age groups. This obstacle, though, does not prevent medical personnel from caring for virus-infected patients. With the appropriate education and advice, apprehension and anxiety will be substituted by confidence in the battle against coronavirus disease

Leadership Competencies Affecting Projects in Organization

Leadership and organizational culture are linked to project performance. The culture of the organization exerts an influence on the leader and shapes the actions and competencies of the leader with the passage of time. For last few decades, project management has extensively been involved in management of projects but still projects are not guaranteed to be successful in various organizational environments. There are certain factors affecting management of projects in different situations where the competence of project leadership is one of the key factors. This chapter employed different keywords and methods for selection of articles synthesizing findings and research gaps of earlier studies. This chapter offers certain limitations and future directions for researchers. The outcomes of this chapter are expected to advance the body of knowledge and help the practitioners in the field of leadership and project management

A brief report of research activities of Indus Institute of Higher Eduction (IIHE) Karachi, Pakistan 2007-2010 (August)

An attempt has been made to summarize the past performance of “Indus Institute of Higher Education” (IIHE) relating to research work already done or being done in its different faculties. In fact this Institute is actively involved in research activities but never reflected them in any correspondence. This Institute is regularly publishing its academic journal with contribution from within the country and qualified researchers from abroad. Four active researchers, of this Institute, are registered and contributing articles in research journals and MPRA working paper series at national and international level. For the students of Bachelors and Masters Research Projects are mandatory for award of Degrees. The Institute has already started M.Phil and Ph.D programs and from the first batch of M.Phil a few students have already submitted their Thesis. The 2nd batch of M.Phil [16 students) is doing its thesis writing. As per HEC’s requirements every faculty have to contribute at least 2 articles at national and international level. In this respect the IIHE has planned to publish one working paper series and four e-journals in the field of textile, engineering and technology, education and economics. The management has decided to make it mandatory for every faculty to contribute at least two research papers/reports per annum. To achieve this objective Research Office has decided to train all the faculty members of the Institute through workshops etc. in order to creating awareness in Faculty members as well as students of MBA, BBA, M.Ed. and B.S.T. to use research-based structure and methodologies that are requisite for M.Phil. Or Ph.D students.Research Activities; IIHE, Cell; RePEc; Journal

The Catch-22 in Prison Privatization: The Problem with the Solution

A step into just about any state prison in the United States reveals an institution plagued by over-population, with just about every prison running at more than 100% capacity. The problem, of course, is not new but one that has received great attention. In the past decade or so the solution has been privatization of state prisons. Proponents of privatization have pushed forth the idea that private institutions are the solution to prison overcrowding. However, by looking to for-profit private institutions as a means to resolving the problems of the penal system, are legislators in fact ensuring that the problems continue? This article will show that there is indeed a “Catch-22.” Prison privatization is the solution to a problem, which if solved would render the need for privatization obsolete. Thus, if private institutions actually solved the prison population crisis there would be no need for privatization and no profits. The end result is that the privatization industry works to ensure the penal system’s problems continue and that they, the private companies, continue to exist as the solution

The experience of witnesses who testified at the Truth and Reconciliation Commission: testimonial process and psychological healing in the aftermath of trauma

The aim of the study was to examine the relationship between the experience of testifying before the TRC among victims and survivors of gross human rights abuses, and the objectives that were set out by the TRC with regard to healing
