The Relationship Between Belief and Credence

Sometimes epistemologists theorize about belief, a tripartite attitude on which one can believe, withhold belief, or disbelieve a proposition. In other cases, epistemologists theorize about credence, a fine-grained attitude that represents one’s subjective probability or confidence level toward a proposition. How do these two attitudes relate to each other? This article explores the relationship between belief and credence in two categories: descriptive and normative. It then explains the broader significance of the belief-credence connection and concludes with general lessons from the debate thus far

Computational fact checking from knowledge networks

Traditional fact checking by expert journalists cannot keep up with the enormous volume of information that is now generated online. Computational fact checking may significantly enhance our ability to evaluate the veracity of dubious information. Here we show that the complexities of human fact checking can be approximated quite well by finding the shortest path between concept nodes under properly defined semantic proximity metrics on knowledge graphs. Framed as a network problem this approach is feasible with efficient computational techniques. We evaluate this approach by examining tens of thousands of claims related to history, entertainment, geography, and biographical information using a public knowledge graph extracted from Wikipedia. Statements independently known to be true consistently receive higher support via our method than do false ones. These findings represent a significant step toward scalable computational fact-checking methods that may one day mitigate the spread of harmful misinformation

Effect of Armed Banditry on Educational Outcomes in Affected Rural Communities of Katsina State, Nigeria

Measuring educational outcomes in terms of enrolment, attendance, academic performance and teacher effectiveness, the effect of armed banditry was investigated in affected rural communities in three Local Government Areas of Katsina State, namely; Jibia, Batsari, and Danmusa. Obtaining cross-sectional data from 450 respondents encompassing parents, students and school administrators in primary and post-primary schools in the affected communities, the Ordinary Least Squares regression technique was deployed for the analysis. Armed banditry was found to have a negative effect on educational outcomes, and this effect was found to be significant for all the educational indicators. Based on these findings, policy interventions including increased security funding, community engagement, and targeted training are recommended to mitigate these impacts. Specifically, deployment of local vigilantes, embarking on mass orientation on various response measures that can be adopted by citizens before, during and after attacks are recommended. Overall, addressing armed banditry in all its ramifications is imperative in order to improve educational outcomes in the affected rural communities of Katsina State in particular and Nigeria in general

Preparation and Evaluation of Silymarin β-cyclodextrin Molecular Inclusion Complexes

Silymarin is a hepatoprotective agent, having poor water solubility and oral absorption of about 23 – 47%, leading to low bioavailability of the drug. The aim of the present study is to improve the solubility and dissolution rate and in turn the hepatoprotective activity of the drug, by formulating its inclusion complex with beta (β)-cyclodextrin, using different methods. The phase solubility analysis indicates the formation of 1:1 molar inclusion complex of the drug with beta cyclodextrin. Apparent stability constant for Silymarin (Kc) was 722 K-1 with β-cyclodextrin complex. The inclusion complexes were prepared by four different methods, namely, physical mixing, kneading, co-precipitation, and solvent evaporation. The prepared complexes were characterized using differential scanning colorimetry, scanning electron microscopy, and x-ray diffractometry. The inclusion complex prepared by the co-precipitation methods exhibits an overall best result, with respect to the formulation of sustained release formulations

Anti-Luck Epistemology and the Gettier Problem

A certain construal of the Gettier problem is offered, according to which this problem concerns the task of identifying the anti-luck condition on knowledge. A methodology for approaching this construal of the Gettier problem—anti-luck epistemology—is set out, and the utility of such a methodology is demonstrated. It is argued that a range of superficially distinct cases which are meant to pose problems for anti-luck epistemology are in fact related in significant ways. It is claimed that with these cases properly understood, anti-luck epistemology is able to offer a suitable diagnosis of them which doesn’t threaten the necessity of the anti-luck condition for knowledge

A sensitive virtue epistemology

We offer an alternative to two influential accounts of virtue epistemology: Robust Virtue Epistemology (RVE) and Anti-Luck Virtue Epistemology (ALVE). We argue that while traditional RVE does offer an explanation of the distinctive value of knowledge, it is unable to effectively deal with cases of epistemic luck; and while ALVE does effectively deal with cases of epistemic luck, it lacks RVE’s resources to account for the distinctive value of knowledge. The account we provide, however, is both robustly virtue-theoretic and anti-luck, having the respective benefits of both rival accounts without their respective shortcomings. We describe this view here
