Standard Bearers

In both ethics and epistemology an important question is whether justification is a fully internal or a partly external matter. In view of analogies between relevant considerations in each area, I recommend distinguishing, as basic and independent subjects of normative status, (i) people and (ii) what they do. Evaluations of subjects, on one hand, and of their beliefs and actions, on the other, are less intimately related than is presupposed. This helps resolve internalism/externalism controversies in both domains. An important related advantage of the distinction is its effect on our understanding of normative luck, both moral and epistemic

The Proper Work of the Intellect

There is a familiar teleological picture of epistemic normativity on which it is grounded in the goal or good of belief, which is taken in turn to be the acquisition of truth and the avoidance of error. This traditional picture has faced numerous challenges, but one of the most interesting of these is an argument that rests on the nearly universally accepted view that this truth goal, as it is known, is at heart two distinct goals that are in tension with one another. This paper will look more closely at the standard way of understanding the truth goal, drawing out both its explicit and implicit features. My aim will be to show that this conception of the truth goal is deeply mistaken, to propose and defend an alternative model, and to show how this alternative model restores the unity of the goal and its potential to ground and explain the normative dimensions of belief

Dirac Structures and Hamilton-Jacobi Theory for Lagrangian Mechanics on Lie Algebroids

This paper develops the notion of implicit Lagrangian systems on Lie algebroids and a Hamilton--Jacobi theory for this type of system. The Lie algebroid framework provides a natural generalization of classical tangent bundle geometry. We define the notion of an implicit Lagrangian system on a Lie algebroid $E$ using Dirac structures on the Lie algebroid prolongation \T^EE^*. This setting includes degenerate Lagrangian systems with nonholonomic constraints on Lie algebroids.Comment: 22 pages. arXiv admin note: text overlap with arXiv:0706.278

Classroom Discussions as Distortions: Examining Discriminatory Teacher Practices

Ms. Mendez, English Department chair in a large urban high school, has noticed a persistent pattern in the practices of her colleagues. These practices tend to be racially insensitive and emphasize a noncritical view that does not attend to students’ experiences and positions students from a deficit perspective. Realizing that such practices serve as social reproductions of racist and classist orientations that reproduce the existing social order, Ms. Mendez decided school leadership should be informed. However, she worries that the school’s leadership will not work to enact change and instead will take her concerns lightly

Development of a ROV titanium manipulator for light work class ROV vehicles

This paper shows the development of a high technical equipment to be used as tooling of submersible ROV (Remote Operated Vehicles) for offshore operations, particularly the design and fabrication by Additive Manufacturing (AM) of a Titanium Manipulator for ROVs. From the initial concept and design until a new formed company “TITANROB”, this document shortly describes the fabrication of hydraulic titanium manipulators for mid size ROV vehicles, the TitanRob series M501, G500 and the M700.Peer Reviewe
