Evidential Preemption occurs when a speaker asserts something of the form “Others will tell you Q, but I say P,” where P and Q are incompatible in some salient way. Typically, the aim of this maneuver is to get the audience to accept P despite contrary testimony of others, who might otherwise be trusted on the matter. Phenomena such as echo chambers, conspiracy theories, and other political speech of interest to epistemologists today, all commonly involve evidential preemption, so the question (...) arises: What effect, if any, does evidential preemption have on the audience's epistemic situation? In a widely discussed paper, Begby (Philosophy and Phenomenological Research, 2021, 102, 515) argues that evidential preemption can change the audience's epistemic situation in such a way that future testimony that Q, which would otherwise have been persuasive, can be rationally discounted to a significant degree. If so, evidential preemption is not a mere rhetorical flourish, but rather results in a rationally insulated belief that P. Since evidential preemption is a common feature of echo chambers and conspiracy theories, this would be a disturbing result. We bring good news: it is not so, at least not in the way Begby suggests. If evidential preemptions can change one's epistemic situation in a worrying way, it is a mystery how. (shrink)

The use of human subjects in research comes with lots of ethical challenges. The purpose of this review is to assess the various ethical issues that have been associated with biomedical research in Nigeria. This article also finds out the possible ways of improvement of this scenario. Pubmed/Medline, Google Scholar, JSTOR, and AJOL search were the possible search engine for literature from 2000 to 2020. Key words were used including, ethical issues, biomedical research and Nigeria. Of the 113 publications were (...) found., A total of 18(15.9%) articles fulfilled the study inclusion criteria and were included in this review. Twelve ethical issues were highlighted including Informed consent (12 studies), autonomy and voluntariness (8 studies), beneficence (8 studies), counseling (5 studies), compensation (4 studies), professional behavior and attitudes (2 studies), confidentiality (2 studies), social, cultural and religious practices (2 studies), scientific integrity (1 study), communitarianism (1 study), equity (1 study), and trust (1 study). We found that there are ethical issues in biomedical research in Nigeria of which informed consent is most widely studied. Also, participants had varying degree of understanding of their rights as research subjects. As a result, there is need to enhance the capacity of investigators to better understand these issues and also increase their explanatory skill to help participants achieve complete understanding of their various rights and process.

Schwartz developed his Theory of Basic Human Values and corresponding instruments, the portrait values questionnaire (PVQ) and the Schwartz values survey (SVS), in order to measure personal values. He uses these instruments (in a slightly modified form) in conjunction with his Theory of Cultural Value Orientations to measure cultural or societal values. His theoretical work is also used in studying organizational values; however, none of these instruments seem suitable to compare personal and perceived organizational values. If the PVQ is widely (...) used to measure personal values, and we need commensurate measures of the person and organization for comparative analysis, then can we not minimally adjust the PVQ to measure organizational values? In this article we discuss the testing of one such adjusted PVQ used for gauging universities’ organizational values. We developed the PVQ-uni to measure university values as perceived by students. We collected data from sociology departments at two universities, one in Austria ( n = 133) and one Nigeria ( n = 156). We then tested the reliability and the validity of the new instrument. Based on the data collected, we found that the PVQ-uni is a reliable and valid instrument; however, further refinements are needed for the instrument to be used successfully in Africa. (shrink)

Este trabalho faz uma breve apresentação do romance de estréia do autor igbo/nigeriano Chigozie Obioma, Os Pescadores. Veremos como a crítica internacional o está comparando com Chinua Achebe, autor de O Mundo se Despedaça. Depois disso, apresentaremos brevemente a obra mostrando o paralelo que o autor faz com a fundação da Nigéria. Por fim, percorreremos as ideias de nação enquanto comunidades imaginadas, modelo incorporado pelos africanos a partir do contato com os colonizadores.
