Concept Analysis: Engagement in Personal HIV Management  [PDF]
Matt L. Pimentel
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101608
Abstract: A concept analysis is an endeavor in social sciences to ensure proper usage of the term among researchers, theorists, and practitioners. The concept of engagement has recently been touted as the term describing HIV-infected individuals who are compliant with their highly active antiretroviral therapy (HAART) medications. Accordingly, engagement has also come to mean that the full compliance with not just HAART, but also compliance with lab tests, medical visits, and counseling services. Post-release incarcerated male inmates that are HIV-infected (IMIHIV) are an especially vulnerable population in regard to access to care and compliance with HAART medications and services. Therefore, full understanding of the meaning and context of the term engagement is imperative to begin a conversation about these individuals. Thus, engagement in personal HIV management will be stressed.
Syndemic Theory and Male Same Sex Intimate Partner Violence: An Urban/Non-Urban Comparison  [PDF]
Matt L. Pimentel, An-Lin Cheng, Patricia J. Kelly
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101407
Abstract: Background: The majority of research with gay men has been conducted in urban populations, with minimal work on partner violence in non-urban (suburban and rural) settings. Syndemic theory, the concept that negative health outcomes are increased with the addition of each new deleterious health variable, has been used to understand partner violence. The aim of the study was to determine differences in prevalence and associated factors of male same-sex intimate partner violence (MSSIPV) among gay men residing in urban versus non-urban settings. Methods: A cross-sectional survey was conducted with gay men in the state of California. Variables were identified from syndemic theory and included exposure to intimate partner violence, depression, sexual compulsivity, poly-drug use, and childhood sexual abuse. Results: Demographic differences were evident between urban and non-urban dwelling gay men. Rates of lifetime victimization and perpetration of MSSIPV between urban and non-urban gay men were not significant. In regard to syndemic variables, only childhood sexual abuse (CSA) showed any significant differences between the two populations. Being a victim of CSA increased the odds of being a lifetime victim of MSSIPV by a factor of five for non-urban participants and increased the odds of being a victim by a factor of three for all subjects. Moreover, being a victim of CSA increased the odds of being a lifetime perpetrator of MSSIPV by a factor of three for non-urban participants. Conclusion: This appears to be the first of its kind study differentiating between urban and non-urban MSM. More research is needed to verify our findings of demographic and syndemic differences between these two populations in order to fully understand and address the needs of all members of the Lesbian, Gay, Bisexual, and Transgender (LGBT) community.
O desafio da tartaruga humeana
Pimentel, Elson L. A.;
Kriterion: Revista de Filosofia , 2003, DOI: 10.1590/S0100-512X2003000200010
Abstract: i describe in this article the arguments that blackburn put in dispute between achilles and the turtle regarding the reasons that motivate human actions. for they sign sharply humean positions, the ideas of the turtle are not framed perfectly in none of the polarizing currents of the contemporary philosophy regarding the theme, although close to neo-humean pole. in this way, the so called ";humean challenge";, that throws to the proponent of categorical reasons the onus to argue for their existence, become worsened by the return to the hume original position that there are no reasons, be them hypothetical or categorical, that could move human being, just passions.

Electromagnetic Field in Some Anisotropic Stiff Fluid Universes
Pimentel L O
Physics , 1995,
Abstract: The electromagnetic field is studied in a family of exact solutions of the Einstein equations whose material content is a perfect fluid with stiff equation of state (p = $\epsilon $ ). The field equations are solved exactly for several members of the family.
Inflationary Consistency Conditions from a Wavefunctional Perspective
Guilherme L. Pimentel
Physics , 2013, DOI: 10.1007/JHEP02(2014)124
Abstract: It is shown that the squeezed limit of inflationary expectation values follows from reparametrization invariance of the wavefunction of the universe. This translates into a constraint on the longitudinal modes of functional derivatives of the wavefunction. Thus, the local non-Gaussianity induced by single field inflation is purely a gauge artifact, and should not yield a physically measurable effect. We focus on Einstein gravity in de Sitter space and single field inflation, although the formalism only relies on the diffeomorphism invariance of the theory, and thus applies to any theory of gravity.
On-brane data for braneworld stars
Matt Visser,David L. Wiltshire
Physics , 2002, DOI: 10.1103/PhysRevD.67.104004
Abstract: Stellar structure in braneworlds is markedly different from that in ordinary general relativity. As an indispensable first step towards a more general analysis, we completely solve the ``on brane'' 4-dimensional Gauss and Codazzi equations for an arbitrary static spherically symmetric star in a Randall--Sundrum type II braneworld. We then indicate how this on-brane boundary data should be propagated into the bulk in order to determine the full 5-dimensional spacetime geometry. Finally, we demonstrate how this procedure can be generalized to solid objects such as planets.
Stable gravastars - an alternative to black holes?
Matt Visser,David L. Wiltshire
Physics , 2003, DOI: 10.1088/0264-9381/21/4/027
Abstract: The "gravastar" picture developed by Mazur and Mottola is one of a very small number of serious challenges to our usual conception of a "black hole". In the gravastar picture there is effectively a phase transition at/ near where the event horizon would have been expected to form, and the interior of what would have been the black hole is replaced by a segment of de Sitter space. While Mazur and Mottola were able to argue for the thermodynamic stability of their configuration, the question of dynamic stability against spherically symmetric perturbations of the matter or gravity fields remains somewhat obscure. In this article we construct a model that shares the key features of the Mazur-Mottola scenario, and which is sufficiently simple for a full dynamical analysis. We find that there are some physically reasonable equations of state for the transition layer that lead to stability.
Proceedings Thirteenth International Workshop on the ACL2 Theorem Prover and Its Applications
Matt Kaufmann,David L. Rager
Computer Science , 2015, DOI: 10.4204/EPTCS.192
Abstract: This volume contains the proceedings of the Thirteenth International Workshop on the ACL2 Theorem Prover and Its Applications, ACL2 2015, a two-day workshop held in Austin, Texas, USA, on October 1-2, 2015. ACL2 workshops occur at approximately 18-month intervals and provide a major technical forum for researchers to present and discuss improvements and extensions to the theorem prover, comparisons of ACL2 with other systems, and applications of ACL2 in formal verification. ACL2 is a state-of-the-art automated reasoning system that has been successfully applied in academia, government, and industry for specification and verification of computing systems and in teaching computer science courses. In 2005, Boyer, Kaufmann, and Moore were awarded the 2005 ACM Software System Award for their work on ACL2 and the other theorem provers in the Boyer-Moore family.
O desempenho dos cuidadores informais na avalia??o da qualidade de vida dos doentes oncológicos uma revis?o do tema
Oliveira,Alexandra; Pimentel,Francisco L.;
Psicologia, Saúde & Doen?as , 2006,
Abstract: one of the main goals of the interventions with cancer patients is proportionate the best quality of life (qol) to the patient. however, it is often difficult to determine the health related quality of life (hrqol) of same cancer patients because psychological, cognitive and physical problems limit their ability to complete questionnaires. a proxy, such as family member, may be able to give accurate information about patients hrqol, information with a great importance for medical decisions. the aim of this article is to proportionate a literature review on the viability in use the proxy derived information on patient qol, using the results of previous studies. it is hoped that this article may contribute and promote, in portugal a better understanding and investigation about this issue.
