Response-ability Revisited: Towards Re(con)figuring Scientific Literacy

The purpose of this chapter is to revisit and expand upon the concept of response-ability, shifting from the deconstructive homework of previous chapters to working towards a reconstructive response which renders science education more hospitable towards Indigenous science to-come. Braiding in the work of Torres Strait Islander scholar Martin Nakata’s theorizing of the cultural interface, which accounts for the ways in which hybridity between ways-of-knowing-in-being are unequal, problematic, and yet rife with possibility, this response takes the form of re(con)figuring scientific literacy. In four movements, this response: a) identifies scientific literacy as a central yet uncertain concept whose critical inhabitation is ripe for other meanings and enactments; b) explores Karen Barad’s subversion of scientific literacy as agential literacy as a productive location to rework the connectivity towards IWLN and TEK; c), utilizes agential literacy as proximal (yet differing) relation to bring in Gregory Cajete’s conception of Indigenous science as ecologies of relationships; and d) explores the generative points of resonance between agential literacy and ecologies of relationships. The chapter concludes with a cautionary note on points of convergence and points of divergence, wherein the proximal relation between agential literacy and ecologies of relationships is productively troubled.

Case Report: Median nerve formation; an unusual position in the right upper extremity with clinical relevance

There was no direct relationship between its formation and the axillary artery. Hence, it may be not be readily compromised. The site of MN formation was in proximal relation to the insertion of the coracobrahialis. This is clinically important as it may give a reinforced innervation to the muscle and proprioceptive impulses to medial fibres of the brachialis muscle. Conversely, the MN may be compressed by the tendon of the coracobrahialis, affecting its sympathetic filaments to the brachial artery. Furthermore, when present, it may be severed during reconstructive surgeries around the mid arm as the medial intermuscular septum fades out above the insertion of the coracobrachialis muscle. This report highlights the presence of a significant anatomical variation of the median nerve with regards to its site of formation, roots morphology and distribution, as well as its arterial relations for proper planning of surgeries.Key Words: Median nerve, arterial relations, right upper extremity, Morphology.

Directional dynamical cubes for minimal -systems

We introduce the notions of directional dynamical cubes and directional regionally proximal relation defined via these cubes for a minimal $\mathbb{Z}^{d}$-system $(X,T_{1},\ldots ,T_{d})$. We study the structural properties of systems that satisfy the so-called unique closing parallelepiped property and we characterize them in several ways. In the distal case, we build the maximal factor of a $\mathbb{Z}^{d}$-system $(X,T_{1},\ldots ,T_{d})$ that satisfies this property by taking the quotient with respect to the directional regionally proximal relation. Finally, we completely describe distal $\mathbb{Z}^{d}$-systems that enjoy the unique closing parallelepiped property and provide explicit examples.

Null systems in the non-minimal case

In this paper, it is shown that if a dynamical system is null and distal, then it is equicontinuous. It turns out that a null system with closed proximal relation is mean equicontinuous. As a direct application, it follows that a null dynamical system with dense minimal points is also mean equicontinuous. Meanwhile, a distal system with trivial $\text{Ind}_{\text{fip}}$-pairs and a non-trivial regionally proximal relation of order $\infty$ are constructed.

Relativization of sensitivity in minimal systems

Let $\unicode[STIX]{x1D70B}:(X,T)\rightarrow (Y,S)$ be an extension between minimal systems; we consider its relative sensitivity. We obtain that $\unicode[STIX]{x1D70B}$ is relatively $n$-sensitive if and only if the relative $n$-regionally proximal relation contains a point whose coordinates are distinct; and the structure of $\unicode[STIX]{x1D70B}$ which is relatively $n$-sensitive but not relatively $(n+1)$-sensitive is determined. Let ${\mathcal{F}}_{t}$ be the families consisting of thick sets. We introduce notions of relative block ${\mathcal{F}}_{t}$-sensitivity and relatively strong ${\mathcal{F}}_{t}$-sensitivity. Let $\unicode[STIX]{x1D70B}:(X,T)\rightarrow (Y,S)$ be an extension between minimal systems. Then the following Auslander–Yorke type dichotomy theorems are obtained: (1) $\unicode[STIX]{x1D70B}$ is either relatively block ${\mathcal{F}}_{t}$-sensitive or $\unicode[STIX]{x1D719}:(X,T)\rightarrow (X_{\text{eq}}^{\unicode[STIX]{x1D70B}},T_{\text{eq}})$ is a proximal extension where $(X_{\text{eq}}^{\unicode[STIX]{x1D70B}},T_{\text{eq}})\rightarrow (Y,S)$ is the maximal equicontinuous factor of $\unicode[STIX]{x1D70B}$. (2) $\unicode[STIX]{x1D70B}$ is either relatively strongly ${\mathcal{F}}_{t}$-sensitive or $\unicode[STIX]{x1D719}:(X,T)\rightarrow (X_{d}^{\unicode[STIX]{x1D70B}},T_{d})$ is a proximal extension where $(X_{d}^{\unicode[STIX]{x1D70B}},T_{d})\rightarrow (Y,S)$ is the maximal distal factor of $\unicode[STIX]{x1D70B}$.
