Introduction: Researching and Rethinking the Labors of Love
Authors: Olcott Jocelyn 
Published: December 2010

Abstract
This introduction situates the articles in this special issue within the broader United States and Latin American historiographies of reproductive labor—the unpaid “caring” work of childcare, housekeeping, food provision, and the maintenance of critical community networks. It explores the conceptual and methodological issues raised in studying labor that individual actors often performed in both public and private realms and in commodified and uncommodified forms. By considering studies dating back to the colonial period and across the Americas, this essay explores the historical contingencies of reproductive labor with particular attention to the specificities of social relations, the impact of modernization and industrialization, and the role of policy makers and state agencies. These studies underscore the challenges of defining and researching this understudied area of labor history and its potential contributions to other historical subfields, especially family, economic, political, social, and cultural history. The introduction concludes with a brief delineation of the articles’ methodological contributions and promising directions in the study of reproductive-labor history.
Entertaining Inequalities: Doña Petrona, Juanita Bordoy, and Domestic Work in Mid-Twentieth-Century Argentina
Authors: Pite Rebekah E. 
Published: December 2010

Abstract
Over the course of the mid-twentieth century Doña Petrona C. de Gandulfo established herself as Argentina’s leading domestic expert. Her popularity reached new heights when she began broadcasting her cooking lessons on television with her assistant, Juanita Bordoy. In this article, Rebekah Pite explores the model of domestic work portrayed by these two women in comparison to that of other Argentine homemakers and their paid help during the 1950s and 1960s. She does so by drawing from a broad source base that includes oral histories, television programming, cookbooks, magazines, and government and legal documents. She finds that Doña Petrona and Juanita Bordoy’s public interactions were both captivating and open to critique because they enabled others to observe a typically private domestic relationship during a period in which many women’s relationships to domesticity and to paid work were in flux. Pite argues that to understand the tensions surrounding these changes, we must shift our framework and our terminology. While scholars of Latin America have tended to cast domestic work relationships as paternalistic, the bonds of power and affection between Doña Petrona and Juanita Bordoy—and countless other domestic pairs—were (and continue to be) more maternalistic in nature. Her research suggests that middle-class or elite women, as opposed to their male partners, have often taken the lead in negotiating the affective terms of these relationships as well as the work to be done.

Abstract
A new block copolymer of cycloolefin was synthesized by catalytic block copolymerization. Nanoscaled phase separation of the block copolymer was observed by TEM, demonstrating the formation of the block copolymer by this method. The coexistence of plural nanostructures might be caused by broader polydispersity of the block copolymer.
Multivariate Analysis of Clinical, Demographic, and Laboratory Data for Classification of Disorders of Calcium Homeostasis

Published: December 2010

Abstract
Parathyroid hormone (PTH) nomograms combine total calcium and intact PTH (iPTH) measurements to classify disorders of calcium homeostasis. Our objective was to determine if using a combination of laboratory, demographic, and clinical parameters improves the accuracy of classification of these disorders. Chart data were collected for 236 patients with physician-ordered iPTH and total calcium tests. Classification was done using 3 approaches: (1) PTH nomogram plotting total calcium and iPTH results against known cases; (2) review of all available chart data (“gold standard”); and (3) multivariate model (classification and regression tree [CART] or logistic regression) using 24 variables. The CART model was developed using the gold standard patient classification and validated using leave-one-out cross-validation. The CART model was significantly (P = .002) more accurate (80.6%) than the PTH nomogram (59.7%) and logistic regression (66.2%) at classifying calcium homeostasis disorders. The CART model used 6 of 24 variables (iPTH, calcium, creatinine, renal transplantation, percentage of females, and urea nitrogen) and had a misclassification error rate of 0.194 (27/139). Classification of disorders of calcium homeostasis based on the PTH nomogram can be improved by using the CART model developed in this study.
Pure Sarcomatoid Carcinoma of Maxillary Sinus and Nasal Cavity Simulating Malignant Fibrous Histiocytoma
Authors: Terada Tadashi 
Published: December 2010

Abstract
Although a few cases of sinonasal carcinoma with focal sarcomatous differentiation have been reported, pure sarcomatoid carcinoma has not been reported in the English literature. Imaging studies and gross inspection in a 60-year-old man with left-sided face pain revealed a mass in the left maxillary sinus and nasal cavity. A large incisional biopsy specimen from the nasal cavity revealed proliferation of malignant spindle and round cells with a malignant fibrous histiocytoma (MFH) pattern. Tumor giant cells were scattered, and there were areas of a vague storiform pattern. Mitotic figures were numerous. Carcinomatous component was not recognized. The histologic diagnosis was storiform-pleomorphic MFH. Tumor cells were positive for pancytokeratins AE1/3, KL-1, and CAM5.2 and cytokeratin (CK) 18, vimentin, CD68, p53, Ki-67 (labeling, 90%), α1-antitrypsin, and α1-antichymotrypsin and negative for pancytokeratin WSS, CK 34βE14, CK7, CK8, CK14, CK19, CK20, epithelial membrane antigen, S-100 protein, desmin, α-smooth muscle actin, CD34, HMB45, chromogranin, synaptophysin, myoglobin, CD45, CD30, and CD15. Because keratins were positive in tumor cells, a diagnosis of sarcomatoid carcinoma simulating MFH was made. The patient was treated with chemoradiation without significant effect and died 9 months after initial examination.

Abstract
Detection of circulating tumor cells (CTCs) morphologically may be a promising new approach in clinical oncology. We tested the reliability of a cytomorphologic approach to identify CTCs: 808 blood samples from patients with benign and malignant diseases and healthy volunteers were examined using the isolation by size of epithelial tumor cell (ISET) method. Cells having nonhematologic features (so-called circulating nonhematologic cells [CNHCs]) were classified into 3 categories: CNHCs with malignant features, CNHCs with uncertain malignant features, and CNHCs with benign features. CNHCs were found in 11.1% and 48.9% of patients with nonmalignant and malignant pathologies, respectively (P &lt; .001). CNHCs with malignant features were observed in 5.3% and in 43.1% of patients with nonmalignant and malignant pathologies, respectively. Cytopathologic identification of CTCs using the ISET method represents a promising field for cytopathologists. The possibility of false-positive diagnosis stresses the need for using ancillary methods to improve this approach.

Published: December 2010

Abstract
Mutations in the isocitrate dehydrogenase 1 (IDH1) and IDH2 genes are reported in acute myeloid leukemia (AML). We studied the frequency and the clinicopathologic features of IDH1 and IDH2 mutations in AML. Mutations in IDH1 (IDH1R132) and IDH2 (IDH2R172) were assessed by Sanger sequencing in 199 AML cases. Point mutations in IDH1R132 were detected in 12 (6.0%) of 199 cases and in IDH2R172 in 4 (2.0%) of 196 cases. Of the 16 mutated cases, 15 (94%) were cytogenetically normal, for an overall frequency in this group of 11.8%. IDH1R132 and IDH2R172 mutations were mutually exclusive. Concurrent mutations in NPM1, FLT3, CEBPA, and NRAS were detected only in AML with the IDH1R132 mutation. The clinical and laboratory variables of patients with AML with IDH mutations showed no significant differences compared with patients with wild-type IDH. We conclude that IDH1R132 and IDH2R172 mutations occur most often in cytogenetically normal AML cases with an overall frequency of approximately 11.8%.
FLT3 and NPM1 Mutations in Myelodysplastic Syndromes
Authors: Bains Ashish , Luthra Rajyalakshmi , Medeiros L. Jeffrey , Zuo Zhuang 
Published: December 2010

Abstract
We reviewed FLT3 and NPM1 mutation data in a large cohort of patients with myelodysplastic syndrome (MDS). The frequencies of FLT3 and NPM1 mutation were 2.0% and 4.4%, respectively, and mutations were restricted to cases of intermediate- and high-risk MDS. Cytogenetic abnormalities were identified in 46.9% of cases. FLT3 mutations were associated with a complex karyotype (P = .009), whereas NPM1 mutations were associated with a diploid karyotype (P &lt; .001). FLT3 mutation (P &lt; .001) was associated with progression to acute myeloid leukemia (AML), as were a higher bone marrow (BM) blast count (P &lt; .001) and complex cytogenetics (P = .039). No patient with an NPM1 mutation alone had disease that progressed to AML. Cox proportional regression multivariate analysis indicated that FLT3 mutation, NPM1 mutation, complex cytogenetics, BM blast count, pancytopenia, and age were independent factors that correlated with progression-free survival. We conclude that FLT3 and NPM1 mutations are rare in MDS, but assessment of mutation status is potentially useful for predicting progression to AML.
Thrombotic Thrombocytopenic Purpura and Urinary Tract Infections
Authors: Park Yara A. , Schultz Elizabeth F. , Hay Shauna N. , Brecher Mark E. 
Published: December 2010

Abstract
Most cases of thrombotic thrombocytopenic purpura (TTP) are considered idiopathic without an identifiable etiologic agent. It has been previously reported that a number of patients with TTP had a urinary tract infection (UTI). Apheresis records were searched for patients with TTP from 1999 through 2007. Records were examined for evidence of UTI, and the patients were divided into 4 groups: 1, laboratory evidence of UTI on admission; 2, UTI just before admission; 3, UTI that developed during hospitalization; and 4, weak laboratory evidence of a UTI. The study included 90 TTP “visits.” (A visit was defined as all admissions for TTP for a specific patient within a 1-month period.) Of the TTP visits, 21 (23%) were associated with UTIs. Group 1 included 7 patients; group 2, 10 patients; group 3, 3 patients; and group 4, 1 patient. This suggests that UTIs might serve as a TTP stimulus. Owing to the relatively strong association of UTIs with TTP, all patients with TTP should be screened for UTI and treated accordingly.
The Changing Spectrum of DNA-Based Specimen Provenance Testing in Surgical Pathology
Authors: Pfeifer John D. , Zehnbauer Barbara , Payton Jacqueline 
Published: December 2010

Abstract
Short tandem repeat (STR) analysis has emerged as the method of choice for testing to resolve specimen source contamination and identity problems that arise in surgical pathology. We studied a series of consecutive cases referred for STR typing during a 5-year period to document the usefulness of the approach and to describe the broadening scope of testing. The series demonstrates that STR-based typing can be applied in virtually any setting in which specimen source confirmation is requested, that STR-based typing is informative in 92% of cases, but that exceptions occasionally arise that complicate test interpretation. The series also demonstrates that in addition to traditional uses of STR typing, testing is now performed in the absence of any direct indication that a specimen mix-up or contamination may have occurred, namely, when the pathologic findings are unexpected or the clinical setting is atypical. The case series underscores the ability of STR testing to detect errors that cannot be captured by current laboratory protocols, a finding that has important implications for patient safety.
Showing silence: David Small's Stitches
Authors: Vgnes yvind 
Published: December 2010

David Small's graphic memoir Stiches (2009), about his childhood and youth in Detroit in the 1950s, is a book of silences: the silence of a withdrawing mother whose compensatory language is to wash the dishes noisily; the silence of a father who goes to the basement to thump
a punching bag; the silence of a little brother who beats incessantly on a drum. In a household in which conversation is infrequent and at best tense, Small is left to guess his way to hidden family stories of both the present (his mother's closeted lesbianism) and the past (the circumstances
surrounding the violent death of a grandfather). The most devastating silences in Small's depiction of his early years, however, grow out of his bouts with cancer, the diagnosis of which his parents left him ignorant about, and that was the cause of tests made by his radiologist father. After
returning from two hospital operations at age 14, Small finds that he has only one vocal cord left, that he has been transformed into a mute teenager in a profoundly malfunctional family.
With reference to the literature on verbal/visual tensions in graphic narrative, various writings on
comics autobiography, as well as to works that address the relationship between trauma and narratology, my article explores the various ways in which Stitches can be said to be showing silence. A book of more images than words, Small's memoir powerfully describes visually a gestic that
articulates painful isolation as a result of various forms of incommunication. Using pen and ink as well as grey-toned watercolour, Small creates a black and white world of shadows and darkness, of starkly precise memories and vivid dreams that blend into one another, of imaginary spaces into
which the pained child at the centre of the story retreats. An image of tearing apart and bringing together, of wounding as well as healing, the stitches of the title refer both to the scar across David's throat and to the way in which he weaves his narrative together, as an attempt at human
recovery against substantial odds.
Daddy's little girl: Multigenerational queer relationships in Bechdel's Fun Home
Authors: Spiers Miriam Brown 
Published: December 2010

In this article I will examine an unusual queer relationship, as represented by comics artist Alison Bechdel, best known for her strip Dykes to Watch Out For. While the fatherdaughter relationship is a common literary theme, it becomes more complicated in Bechdel's graphic memoir
Fun Home, which depicts two generations simultaneously struggling with issues of gender identity. Alison's ability to lead a queer lifestyle exists in sharp contrast to the way that her father, Bruce, has handled his homosexuality. Rather than reacting to her father's example, either
positively or negatively, Alison must create her own narrative, relying primarily on literature to guide the way. Yet, by identifying as queer, Alison opens the door for her father to discuss his sexuality, leading Alison to wonder, Which of us was the father? (Bechdel 2006: 221). Because
of the history of queerness across generations in America, it is Alison who is in a position to set a positive, open example in a queer fatherdaughter relationship.
Adding to the intricate ways in which Alison and Bruce explore their identities and relationship is the fascinating style
in which Bechdel draws both herself and her father. As characters on the page, they look remarkably similar to one another, a coincidence that is reinforced by Bechdel's use of the pose method to draw her memoir that is, she dresses up as the character, takes photos and bases her drawings
on those photos. However, there is more than that at stake: in some panels, Bechdel draws an explicit physical comparison between Alison and Bruce at various stages in their lives. As a comics artist, Bechdel is able to make use of a variety of visual cues that play an important role in her
representation of queer identity.
These visual cues extend to include visual adaptations of texts, from love letters between her parents to excerpts from her father's noted and underlined novels. Using these real documents as evidence, she describes her parents as literary figures rather
than people. This is most noticeable in her extended comparison of herself and her father to Stephen Dedalus and Leo Bloom in Joyce's Ulysses. Such a comparison simultaneously distances the reader and reaffirms the legitimacy of the relationship. The presence of those references serves
to remind us that Alison's relationship to her father is part of a larger literary pattern, something that can be comfortably understood and examined. Not only is Bechdel able to naturalize and familiarize that relationship, the comparison even canonizes it. Bechdel combines familiar, cartoonish
characters with careful textual detail in both her narration and her frequent use of literary citation. Using her own relationship to literature as a way of exploring her relationship with her father, Bechdel is able to tackle the complexity of a multigenerational narrative that is simultaneously
empowering and disempowering, that requires that she both embrace and fear her own queer identity.
Min, a Combinatorial Game Having a Connection with Prime Numbers
Authors: Cairns Grant , Ho Nhan Bao 
Published: December 2010

AbstractWe introduce a two person game played with a pair of nonnegative integers; a move consists of subtracting from the larger integer, a positive integer no greater than the smaller integer. The player who reduces one of the integers to zero wins. The game is curious in several respects: in particular, its Sprague–Grundy values have an interesting connection with prime numbers.
On Solving Games Constructed Using Both Short and Long Conjunctive Sums
Authors: Kane Daniel M. 
Published: December 2010

AbstractIn a 1966 paper by C.A.B. Smith, the short and long conjunctive sums of games are defined and methods are described for determining the theoretical winner of a game constructed using one type of these sums. In this paper, we develop a method for determining the winner of a game constructed using arbitrary combinations of these sums.
Calibrating local volatility in inverse option pricing using the Levenberg–Marquardt method
Authors: Lakhal Aref , Lakhal Mohamed Majdi , Louis Alfred Karl 
Published: December 2010

Abstract
We derive an iterative algorithm for an Inverse Problem of Option Pricing. The aim is to determine the local volatility such that the corresponding solutions of the Black–Scholes equation match the quoted market prices. Market data are given as option prices with different strikes and maturities. This leads to a parameter estimation problem for parabolic differential equations. This inverse problem is nonlinear and ill-posed. To overcome these difficulties, we apply an inexact Newton method. Thus, we derive a regularizing iterative algorithm of Levenberg–Marquardt type. As an underlying operator, we introduce the propagation operator. It maps, for given initial data, the unknown volatility to the final data. Then, we determine its Gâteaux-differential operator via a parabolic equation of second order. Moreover, its corresponding adjoint, called backpropagation operator, is obtained via a backward parabolic equation. Finally, to illustrate the efficiency of the method, we present some numerical results for simulated data and for observations extracted from the market. Besides, we discuss different strategies for choosing the regularizing parameters.

Authors: Ciałkowski Michał J. , Grysa Krzysztof 
Published: December 2010

Abstract
In this article we present different types of Trefftz functions for stationary and non-stationary linear differential equations. The Trefftz methods are then defined and briefly described. One of them, namely the LSM applied to the region divided on finite elements, is discussed. Examples of the T-functions usage in solving inverse problems and smoothing inaccurate input data are presented. Moreover, some remarks concerning nonlinear non-stationary problem of heat conduction is briefly discussed and some open problems are formulated.
A quasi-boundary-value method for the Cauchy problem for elliptic equations with nonhomogeneous Neumann data
Authors: Feng Xiao-Li , Eldén Lars , Fu Chu-Li 
Published: December 2010

Abstract
A Cauchy problem for elliptic equations with nonhomogeneous Neumann data in a cylindrical domain is investigated in this paper. For the theoretical aspect the a-priori and a-posteriori parameter choice rules are suggested and the corresponding error estimates are obtained. About the numerical aspect, for a simple case results given by two methods based on the discrete Sine transform and the finite difference method are presented; an idea of left-preconditioned GMRES (Generalized Minimum Residual) method is proposed to deal with the high dimensional case to save the time; a view of dealing with a general domain is suggested. Some ill-posed problems regularized by the quasi-boundary-value method are listed and some rules of this method are suggested.
Discrepancy curves for multi-parameter regularization
Authors: Lu Shuai , Pereverzev Sergei V. , Shao Yuanyuan , Tautenhahn Ulrich 
Published: December 2010

Abstract
For solving linear ill-posed problems regularization methods are required when the right-hand side is with some noise. In the present paper regularized solutions are obtained by multi-parameter regularization and the regularization parameters are chosen by a multi-parameter discrepancy principle. Under certain smoothness assumptions we provide order optimal error bounds that characterize the accuracy of the regularized solutions. For the computation of the regularization parameters fast algorithms of Newton type are applied which are based on special transformations. These algorithms are globally and monotonically convergent. Some of our theoretical results are illustrated by numerical experiments. We also show how the proposed approach may be employed for multi-task approximation.
Theory and examples of variational regularization with non-metric fitting functionals
Authors: Flemming Jens 
Published: December 2010

Abstract
We describe and analyze a general framework for solving ill-posed operator equations by minimizing Tikhonov-like functionals. The fitting functional may be non-metric and the operator is allowed to be non-linear and non-smooth. In comparison to former results on variational regularization with non-metric fitting functionals we significantly weaken the assumptions for proving convergence rates and, in addition, we extend the results to a wider range of rates. Two examples, coming from imaging applications, show that the developed theory is applicable to practically relevant problems.
