The Story of the Ink and Paint Department
No full textThe Ink and Paint department at the Walt Disney Studios, for a while, was a department completely staffed by women, but this department faded away with the introduction of technology at the studio. There has been a revival in knowing about the Ink and Paint department in recent years and the purpose of this paper is to figure out who owns the revival story because of the biases that surround this department. To understand the complexity of this department and therefore revival, this study was completed in three parts – how the department was viewed in the past (to know how the studio viewed the department during the golden years of the studio), how it is viewed in a museum setting, and how it is viewed in present day with the publication of a book. I found biases in how the story is being told in different settings and the format of telling these stories greatly impact how the public then views these stories as well. The story that is being presented as the truth was told though the lens of unbiased sources such as a museum, but these entities actually hold many biases, but they have the privilege of controlling how the Ink and Paint department is viewed in present day
Dhal Bhat and My Dad’s Pizza: Comfort and Steep Learning Curves in Nepal
No full textFood is central to our lives. We cannot live without it; our bodies need it to function. But food has more meaning than energy to move our muscles, to help us think, or give us vital vitamins and minerals. We relate food to experiences. Traveling to new places almost always involves trying local cuisine or local specialties. We find comfort in food; in greasy, cheesy, gooey, delicious foods. We eat to deal with stress, to celebrate joy, to mourn losses. Holidays are almost always associated with foods. Food is not just a physical need, but also an emotional and psychological need or desire. While traveling in Nepal, this became even more true. I spent more time thinking about food, salivating over food, and mourning over food, than I thought possible. Food gave me comfort; it helped me to communicate and bridged the gaps between me and the people of Nepal, while also causing me hardships. In this project I related my experiences with living in Nepal for four months to my obsession with food while I was there

Corporate Social Responsibility, Resource Governance, and Social Reproduction: The State’s Neo-Extractivist Project in the Ecuadorian Amazon
No full textDrawing from qualitative research in the Ecuadorian Amazon, in this paper, we argue that Waorani indigenous people, and their everyday efforts at social reproduction, are sites through which an oil company and the state maintain and legitimize their governance of a complex territory defined at once as a national park, oil concession, and indigenous ancestral territory. Specifically, we show that corporate programs framed as improving living conditions in communities impacted by extraction, and Waorani culture and relationships to nature, are used as tools of resource governance by Repsol to the benefit of the state’s neo-extractivist project, enacted through social relations in this place. Despite the state’s increased role in sites of extraction as a result of its “post-neoliberal” (neo-) extractivist transition, Repsol continues its CSR programs; our focus on the embodied everyday experiences of resource governance in this place reveals that Repsol’s continued CSR-informed approach benefits the state’s neo-extractivist project even though it appears antithetical to “post-neoliberal” resource extraction. In this way, we contribute to the emerging literature on how neo-extractivism is managed and maintained on the ground, providing evidence for why this area of study deserves further research
New perturbation bounds in unitarily invariant norms for subunitary polar factors
No full textLet have generalized polar decomposition with subunitary and positive semidefinite. Absolute and relative perturbation bounds are derived for the subunitary polar factor in unitarily invariant norms and in -norms, that extend and improve existing bounds
Positive solutions of the system of operator equations in Hilbert -modules
No full textNecessary and sufficient conditions are given for the operator system , , , and to have a common positive solution, where \u27s and \u27s are adjointable operators on Hilbert -modules. This corrects a published result by removing some gaps in its proof. Finally, a technical example is given to show that the proposed investigation in the setting of Hilbert -modules is different from that of Hilbert spaces
Proof of a Conjecture of Graham and Lovasz concerning Unimodality of Coefficients of the Distance Characteristic Polynomial of a Tree
No full textThe conjecture of Graham and Lov ́asz that the (normalized) coefficients of the distance characteristic polynomial of a tree are unimodal is proved; it is also shown that the (normalized) coefficients are log-concave. Upper and lower bounds on the location of the peak are established
R\\u27enyi\u27s quantum thermodynamical inequalities
No full textA theory of thermodynamics has been recently formulated and derived on the basis of R\\u27enyi entropy and its relative versions. In this framework, the concepts of partition function, internal energy and free energy are defined, and fundamental quantum thermodynamical inequalities are deduced. In the context of R\\u27enyi\u27s thermodynamics, the variational Helmholtz principle is stated and the condition of equilibrium is analyzed. The %obtained results reduce to the von Neumann ones when the R\\u27enyi entropic parameter approaches 1. The main goal of the article is to give simple and self-contained proofs of important known results in quantum thermodynamics and information theory, using only standard matrix analysis and majorization theory
Explicit Block-Structures for Block-Symmetric Fiedler-like pencils
No full textIn the last decade, there has been a continued effort to produce families of strong linearizations of a matrix polynomial , regular and singular, with good properties, such as, being companion forms, allowing the recovery of eigenvectors of a regular in an easy way, allowing the computation of the minimal indices of a singular in an easy way, etc. As a consequence of this research, families such as the family of Fiedler pencils, the family of generalized Fiedler pencils (GFP), the family of Fiedler pencils with repetition, and the family of generalized Fiedler pencils with repetition (GFPR) were constructed. In particular, one of the goals was to find in these families structured linearizations of structured matrix polynomials. For example, if a matrix polynomial is symmetric (Hermitian), it is convenient to use linearizations of that are also symmetric (Hermitian). Both the family of GFP and the family of GFPR contain block-symmetric linearizations of , which are symmetric (Hermitian) when is. Now the objective is to determine which of those structured linearizations have the best numerical properties. The main obstacle for this study is the fact that these pencils are defined implicitly as products of so-called elementary matrices. Recent papers in the literature had as a goal to provide an explicit block-structure for the pencils belonging to the family of Fiedler pencils and any of its further generalizations to solve this problem. In particular, it was shown that all GFP and GFPR, after permuting some block-rows and block-columns, belong to the family of extended block Kronecker pencils, which are defined explicitly in terms of their block-structure. Unfortunately, those permutations that transform a GFP or a GFPR into an extended block Kronecker pencil do not preserve the block-symmetric structure. Thus, in this paper, the family of block-minimal bases pencils, which is closely related to the family of extended block Kronecker pencils, and whose pencils are also defined in terms of their block-structure, is considered as a source of canonical forms for block-symmetric pencils. More precisely, four families of block-symmetric pencils which, under some generic nonsingularity conditions are block minimal bases pencils and strong linearizations of a matrix polynomial, are presented. It is shown that the block-symmetric GFP and GFPR, after some row and column permutations, belong to the union of these four families. Furthermore, it is shown that, when is a complex matrix polynomial, any block-symmetric GFP and GFPR is permutationally congruent to a pencil in some of these four families. Hence, these four families of pencils provide an alternative but explicit approach to the block-symmetric Fiedler-like pencils existing in the literature
