The purpose of this paper is to present a conceptual framework for examining the impact of the COVID-19 pandemic on working women.

This conceptual paper on women in the formal workforce is grounded within the leadership and organization development literature.

The authors posit the COVID-19 pandemic and the subsequent instability in the US workforce, particularly among women and mothers, is effectively examined through the lens of punctuated equilibrium. Specifically, the widespread disruption initiated by the pandemic provides an opportunity for transformative change within organizations and society. Furthermore, working women impacted during this punctuated equilibrium are likewise positioned for transformation. The authors suggest the pandemic and its impact on the formal workforce can be leveraged for individual and organizational development as well as transformation, resulting in advancement toward self-authorship and increased equity within organizations, respectively.

This paper offers a novel integration and application of three leadership and organization development concepts: punctuated equilibrium, the self-authorship theory and Theory U, to better understand the impact of the COVID-19 pandemic on working women.

A DSIR Sponsored Research Programme on the Development and Application of the Matrix Force Method and the Digital Computer. This work presents a rational method for the structural analysis of stressed skin fuselages for application in conjunction with the digital computer. The theory is a development of the matrix force method which permits a close integration of the analysis and the programming for a computer operating with a matrix interpretive scheme. The structural geometry covered by the analysis is sufficiently arbitrary to include most cases encountered in practice, and allows for non‐conical taper, double‐cell cross‐sections and doubly connected rings. An attempt has been made to produce a highly standardized procedure requiring as input information only the simplest geometrical and elastic data. An essential feature is the use of the elimination and modification technique subsequent to the main analysis of the regularized structure in which all cutouts have been filled in. Current Summary A critical historical appraisal of previous work in the Western World on fuselage analysis is given in the present issue together with an outline of the ideas underlying the new theory.

As a first example of the application of the cut‐out procedure to fuselage problems and the selection of appropriate cut systems, the elimination of a complete ring is discussed in detail. ‘Minimal’, ‘maximal’ and ‘dismembering’ techniques are all applied to singly and doubly connected rings, and attention is drawn to some inadmissible and critical combinations of cuts in order to guide the most effective choice. The second fuselage example treats similarly the removal of a portion only of the ring.

Continuing Chapter V, internal stress resultants are established for the open rings in (he fuselage due to the various statically equivalent and self‐equilibrating load systems. The determination of the frame redundancies leads immediately to the corresponding results for the closed rings. The procedure is developed for both single‐ and double‐cell cross‐sections with cither singly‐or doubly‐connected rings. A brief account is also given of the flexibility of a diaphragm or bulkhead, describing how cither the force or displacement method may be used. The analysis of the fuselage basic system concludes with an investigation of thermal stresses in the closed frames.

The conditioning of the redundancy equations is discussed and a method is given for drastically reducing any serious coupling between primary redundancies originating at the same ring station. Making use of the latent root programme of the computer, a revised transformation matrix, for the definition of the primary redundancies, is developed for the specific cross‐sectional shape and geometry when this is markedly non‐circular. The method is illustrated by application to a number of sample cases. Coupling between redundancies at different ring stations is also discussed, but is not considered to be serious except with unusual patterns of frame flexibility.

In the two short sections which close Chapter VII, an improved ring programme is developed which allows i.a. for the application of externally applied moments on the ring vertices and a preliminary and tentative extension of the analysis takes into account the bending stiffness of some of the flanges. The final chapter returns to the subject of the uniform, circular section fuselage and develops the theory for the polygonized cross‐section in analytical form. Standard expressions are given for the elements of the D,, matrix and application of the analysis to a simple example suggests that the effect of the polygonization on the accuracy of the stress distribution is insignificant.

This paper aims to engage nine women English teachers in exploring their personal memories centered around the perception of their raced, classed and gendered teacher bodies, and led them to conceptualize teaching as invasion.

The process of collective memory work (CMW), a qualitative feminist research method, was used to structure collaborative sessions for the nine women English teachers. In these sessions, the group took up the CMW process as the memories were written, read, analyzed and theorized together.

The analyses of two memories from our group's work builds understanding of how the use of new materialism and a conceptualization of emotions as social, collective and agentic, can expand the understanding of the teacher bodies and disrupt normalizing narratives of teaching and learning. The post-humanist concept of intra-action leads one to better understand the boundaries in the teacher – student relationships that is built/invaded, and to see the ways materials, humans, emotions and discourses are entangled in the teaching encounters.

This study demonstrates how sustained and collective research methodologies like CMW can open space for teachers to more fully explore their identities, encounters and relationships. Further, unpacking everyday classroom moments (through the framework of literacy-as-event) can yield deep and critical understanding of how bodies, emotions and non-human objects all become entangled when teaching becomes an act of invasion.

The series of illustrations to the elimination procedures is concluded with two examples in which the various techniques are again examined critically. The first application considers the important problem of a major cut‐out in a fuselage, extending over a number of panels and bays, and including the attached ring segments. Here the dismembering process appears in its straightforward simplicity and generality a particularly effective choice. The final example investigates the removal of a major substructure from a system in the form of an ‘open’ or ‘closed chain’ of substructures. The discussion on cut‐outs is rounded off with a synopsis of the techniques used and a description of the automatic programme for checking an elimination scheme for any hidden singularities.

A series of examples illustrates the application and results of the method previously given for improving the conditioning of the primary redundancies. The transformation matrix giving locally orthogonal redundancies for the parent station is used also to generate the primary self‐equilibrating stress systems for sections with different (but related) geometry and varying ring stiffness. A double‐cell cross‐section is also treated and a brief investigation shows that the general methods developed for establishing primary redundancies in the fuselage can be usefully and economically applied to certain kinds of wing structure. Preparatory to a detailed discussion of cut‐outs and modifications in the fuselage structure, the necessary general theory is collected and summarized.

This paper continues the theme of the opening Part I by analysing a number of problems designed to illustrate some particular aspects of the general theory. Three are concerned with thermal stresses and the last applies inter alia the theorems on maxima and minima to find lower and upper bounds to the St Venant torsional stiffness of a thin solid section.
