The area of operative metaphysics speaks of a metaphysical system that does not just exist as an ivory tower apart from people’s experience, but one that could be applied to a concrete historical circumstance. This piece studies the concept of being as understood by Pantaleon Iroegbu, as being qua belongingness. The concept of being qua belongingness lies within the parameters of operative metaphysics. Pantaleon’s concept of being is analysed alongside the situation of crisis in the Niger Delta region, (...) which the researcher believes was born out of the feeling of neglect and marginalization. Placed alongside Pantaleon’s philosophy of belongingness which opines that to be is to belong, this piece proposes that if the Niger Delta people are given a sense of belongingness, the crisis in the region would come under a more genuine control.

The segregation of image parts into foreground and background is an important aspect of the neural computation of 3D scene perception. To achieve such segregation, the brain needs information about border ownership; that is, the belongingness of a contour to a specific surface represented in the image. This article presents psychophysical data derived from 3D percepts of figure and ground that were generated by presenting 2D images composed of spatially disjoint shapes that pointed inward or outward relative to the (...) continuous boundaries that they induced along their collinear edges. The shapes in some images had the same contrast (black or white) with respect to the background gray. Other images included opposite contrasts along each induced continuous boundary. Psychophysical results demonstrate conditions under which figure-ground judgment probabilities in response to these ambiguous displays are determined by the orientation of contrasts only, not by their relative contrasts, despite the fact that many border ownership cells in cortical area V2 respond to a preferred relative contrast. Studies are also reviewed in which both polarity-specific and polarity-invariant properties obtain perceptual figure-ground grouping results. The FACADE and 3D LAMINART models are used to explain these data. Keywords: figure-ground separation, border ownership, perceptual grouping, surface filling-in, V2, V4, FACADE Theory. (shrink)

The COVID-19 outbreak spurred unplanned closures and transitions to online classes. Physical environments that once fostered social interaction and community were rendered inactive. We conducted interviews and administered surveys to examine undergraduate STEM students’ feelings of belonging and engagement while in physical isolation, and identified online teaching modes associated with these feelings. Surveys from a racially diverse group of 43 undergraduate students at a Hispanic Serving Institution (HSI) revealed that interactive synchronous instruction was positively associated with feelings of interest and (...) belonging, particularly for students of color, while noninteractive instruction reduced social belonging, but was related to more cognitive engagement. Small group and one-on-one interviews with 23 of these students suggest that students derived feelings of connectedness from their instructors, peers, and prior experiences and relied on their sense of competency to motivate themselves in the course and feel a sense of belonging. Two embedded cases of students in physics classrooms are compared to highlight the range of student feelings of connectedness and competency during the lockdown. Findings reaffirm that social interaction tends to support belonging and engagement, particularly for under-represented (Black or African American and Hispanic) racial groups in STEM. STEM instructors who aim to support feelings of belonging and engagement in virtual learning environments should consider increasing opportunities for student–student and student–teacher interactions, as well as taking a flexible approach that validates and integrates student voice into instruction. Future research is needed to further explore the themes of relatedness and competency that emerged as aspects of course belonging. (shrink)

Recent analyses have critically evaluated the connection of abstract rights with territorial nation-states. This article extends those findings by analyzing the way discourses of rights (human, political, national) are interconnected. It is argued that the system of relations that rights establish between their norms and concrete sociopolitical practices allows rights to function as overall machinery, one that both produces and governs subjects. From this perspective, this article establishes that: (a) since rights depend for their legal guarantee on the power of (...) nation-states, they are a normative standard which coincides with the political power of a nation-state; (b) since rights require a certain ethic from subjects in order that their exercise of rights be legally protectable, they govern subjects through inclusion, that is, by structuring fields of action in order that a certain “proper” conduct may take place; (c) since the nation-state framework with which rights are connected operates in a postcolonial order, the functioning of rights is also connected with the discursive dynamics of postcoloniality. The empirical focus of the discussion is on Pakistan. The first section focuses on the use of human rights’ discourse in order to counter drone attacks in Pakistan’s tribal belt. The conundrums that human rights in this context generate are then filled in by acknowledging “rights” of a state (i.e. political sovereignty and territorial integrity), which is the focus of second section. The third section comments on the way national and political rights correspond to the notions of “citizenship” and “belongingness,” which in turn shapes the conduct of subjects in a contextually apt manner.
