‘The porcupine was a feast’: The Tastes of Luxury and Necessity in Ruby Langford Ginibi’s Storytelling
No full textThis paper brings Bourdieu’s concepts of the tastes of luxury and necessity into dialogue with the alimentary habitus that Bundjalung woman Ruby Langford Ginibi records in her lifewriting. The paper argues that Langford Ginibi’s alimentary disposition has much in common with the taste of necessity that Bourdieu attributes to the French working class. The analysis identifies two further characteristics of her relationship to food that Bourdieu does not describe: an emphasis on recounting the adverse material circumstances in which meals are procured and prepared, and a practise of indiscriminate eating in which foods are deemed uniformly and reliably desirable. The paper finds that, despite some public censure, Langford Ginibi maintains much of her habitus as she accrues social, cultural, and economic capital. It concludes that maintaining and valorising the taste of necessity and its associated habitus may be read as a positive strategy that seeks to restructure the colonial field from below
The Precarious plight of American WorkingClass Faculty: Causes and Consequences
No full textFor working-class Americans, the path of the professor is precarious. The neo-liberalization of higher education and the hegemony of academic elitism have made working-class faculty an endangered, disadvantaged, and invisible minority within the professoriate. On one hand, financing a graduate school career from humble origins is an increasingly risky investment. On the other, working-class Americans who secure a faculty job are often under-matched to low salary, high workload positions and endure classist ostracism and micro-aggressions. This essay is intended to not only trace the tragic trajectory of American working-class faculty but, more importantly, to invite conversations and identify suggestions that lead to our colleges and universities becoming more personally supportive workplaces and professionally empowering platforms for working-class professors
Counting the Working Class for WorkingClass Studies: Comparing Three OccupationBased Definitions
No full textA wide variety of definitions of the working class are in use across disciplines and even within working-class studies (Cohen 2001; Zweig 2001; Metzgar 2003; Wilson 2016; Wilson and Roscigno 2018). Responding to Zweig’s (2016) call to maintain continuity in thinking about the working class in working-class studies by recognizing that ‘the working class continues to exist in capitalist societies, within capitalist class dynamics, in which the organization of production underlies material, cultural, and political experience’ (14), I delineate several definitions of the working class and take a close look at three operationalizations of the working class by occupational aggregations, one each suggested by Metzgar (2003) and Cohen (2001) and one I define, inspired by Florida (2002). Using 2017 American Community Survey data, I compare the demographics and geography of the working class through each of these definitions. I illustrate that by many definitions, the working class is a broad and diverse group of workers who live and work in rural, urban, and suburban places, while inequalities both within the working class and between it and other social classes remain pressing issues for investigation. This paper provides a guide for understanding definitions of the working class that will be useful for working-class studies scholars from all disciplines, regardless of methodologies
Puerto Rican Needle Workers and Colonial Migrations: Deindustrialization as Pathways Lost
No full textThe dominant narrative of U.S. deindustrialization opens with the Northeast as the definitive starting point for industry followed by a direct linear relocation to the South and then the Global South. In this framework, deindustrialization appears to have a logic, a rational pathway following cheaper and compliant labor. When Puerto Rican needleworkers become visible in the history of the textile and garment industry, however, their colonial migrations complicate deindustrialization, and its linear logic collapses. From the perspective of these colonial women, industrialization of Puerto Rico began at the turn of the twentieth century - the same time factories and mills increased in the South. Thousands of women also migrated to the Northeast mainland, especially from the 1950s to the 1970s, when many white workers were mourning the loss of textile and garment jobs. Puerto Rican women moved to the old factories of the Northeast, which had become outposts for large transnational corporations that did not relocate their manufacturing in a direct geographic path but rather spread their processes over any arrangement that offered the best cost-benefit analysis. For Puerto Rican women, employment in the plants of the Northeast during the 1960s and 1970s offered hope rather than despair, and many took pride in meeting their quotas and providing wages for their families. In the 1980s, when the Reagan administration initiated major reforms to financial policies and the practices of leveraged buyouts made closing old plants a better return on investment, Puerto Rican women mourned the loss of jobs in an industry many experts had already declared ‘dead.’ Fragmentation of the archives between Puerto Rican studies and U.S. labor history have allowed for a simplistic narrative of deindustrialization and an erasure of the losses and disappointments of women who left Puerto Rico for the promise of higher wages in the postwar Northeast mainland. When the oral histories and documents related to the migrations of Puerto Rican needleworkers become visible in the larger history of the ‘American working class’, we see deindustrialization as sprawling and contingent rather than as linear and naturalized. Puerto Rican studies scholars have written about needleworkers as part of their field with particular attention to gender as it relates to notions of motherhood, but this article sets the women as American workers into the losses of the textile and garment industry without eliding their specificity as migrating and racialized colonial labor. In addition, the women expressed grief that went beyond losing a specific job - many of these workers lost their place in the U.S. workforce and the promise of financial stability as they became associated with racialized poverty and welfare debates
Great Gray Owl home range and habitat selection during the breeding-season
No full textIdentifying resource requirements of under-studied species during key stages such as breeding is critical for effective management. We quantified breeding-season home-range attributes and habitat selection of adult Great Gray Owls across multiple spatial (home-range and within-home-range level) and temporal (nesting and post-fledging; day versus night) scales in western Wyoming, USA. In 2018 and 2019 we outfitted adult male owls (n = 18) with GPS remote-download transmitters and collected hourly location data throughout the breeding season (1 May – 15 September). Using 50% and 95% kernel density estimates (KDE), mean core area was 1.2 km2 and mean home-range size was 6.2 km2 (n = 16). Resource selection analyses incorporated both remotely-sensed and microsite data. We conducted microsite surveys at used and available points within 95% KDE home ranges using a stratified random sample design (n = 661). Determining home-range and breeding habitat requirements will improve density estimates and facilitate the effective management of Great Gray Owls and their habitat. We found differing patterns between habitat selection at the home-range and within-home-range scales.

Brauer's theorem and nonnegative matrices with prescribed diagonal entries
No full textThe problem of the existence and construction of nonnegative matrices with prescribed eigenvalues and diagonal entries is an important inverse problem, interesting by itself, but also necessary to apply a perturbation result, which has played an important role in the study of certain nonnegative inverse spectral problems. A number of partial results about the problem have been published by several authors, mainly by H. \v{S}migoc. In this paper, the relevance of a Brauer's result, and its implication for the nonnegative inverse eigenvalue problem with prescribed diagonal entries is emphasized. As a consequence, given a list of complex numbers of \v{S}migoc type, or a list with , and being realizable; and given a list of nonnegative real numbers , the remarkably simple condition is necessary and sufficient for the existence and construction of a realizing matrix with diagonal entries Conditions for more general lists of complex numbers are also given
Unions of a clique and a co-clique as star complements for non-main graph eigenvalues
No full textGraphs consisting of a clique and a co-clique, both of arbitrary size, are considered in the role of star complements for an arbitrary non-main eigenvalue. Among other results, the sign of such a eigenvalue is discussed, the neigbourhoods of star set vertices are described, and the parameters of all strongly regular extensions are determined. It is also proved that, unless in a specified special case, if the size of a co-clique is fixed then there is a finite number of possibilities for our star complement and the corresponding non-main eigenvalue. Numerical data on these possibilities is presented
Vector Spaces of Generalized Linearizations for Rectangular Matrix Polynomials
No full textThe complete eigenvalue problem associated with a rectangular matrix polynomial is typically solved via the technique of linearization. This work introduces the concept of generalized linearizations of rectangular matrix polynomials. For a given rectangular matrix polynomial, it also proposes vector spaces of rectangular matrix pencils with the property that almost every pencil is a generalized linearization of the matrix polynomial which can then be used to solve the complete eigenvalue problem associated with the polynomial. The properties of these vector spaces are similar to those introduced in the literature for square matrix polynomials and in fact coincide with them when the matrix polynomial is square. Further, almost every pencil in these spaces can be '`trimmed' to form many smaller pencils that are strong linearizations of the matrix polynomial which readily yield solutions of the complete eigenvalue problem for the polynomial. These linearizations are easier to construct and are often smaller than the Fiedler linearizations introduced in the literature for rectangular matrix polynomials. Additionally, a global backward error analysis applied to these linearizations shows that they provide a wide choice of linearizations with respect to which the complete polynomial eigenvalue problem can be solved in a globally backward stable manner
Minimal Estrada index of the trees without perfect matchings
No full textTrees possessing no Kekul´e structures (i.e., perfect matching) with the minimal Estrada index are considered. Let Tn be the set of the trees having no perfect matchings with n vertices. When n is odd and n ≥ 5, the trees with the smallest and the second smallest Estrada indices among Tn are obtained. When n is even and n ≥ 6, the tree with the smallest Estrada index in Tn is deduced
Generalized Commuting Maps On The Set of Singular Matrices
No full text Let Mn(K) be the ring of all n × n matrices over a field K. In the present paper, additive mappings G : Mn(K) → Mn(K) such that [[G(y), y], y] = 0 for all singular matrix y will be characterized. Precisely, it will be proved that G(x) = λx + µ(x) for all x ∈ Mn(K), where λ ∈ K and µ is a central map. As an application, the description is given of all additive maps g : Mn(K) → Mn(K) such that [[g(yk1 ), yk2 ], yk3 ] = 0 for all singular matrices y ∈ Mn(K), where m ∈ N∗
