Endpoint bounds for a generalized {R}adon transform
Betsy Stovall
Mathematics , 2009, DOI: 10.1112/jlms/jdp033
Abstract: We prove that convolution with affine arclength measure on the curve parametrized by $h(t) := (t,t^2,...,t^n)$ is a bounded operator from $L^p(\mathbb{R}^n)$ to $L^q(\mathbb{R}^n)$ for the full conjectured range of exponents, improving on a result due to M. Christ. We also obtain nearly sharp Lorentz space bounds.
Do We Have an Inborn Moral Sense?  [PDF]
Marilyn Walker
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.44062
Abstract: This paper reviews some recent work in the relationship between caring behavior among humans, an evolutionary adaptation necessary for survival of the species, and our moral sense of right and wrong. The investigation presents some of our current understandings; the question is part of ongoing work in neuroscience and evolutionary biology. Does caring behavior necessarily imply a moral sensibility?
Uniform estimates for the X-ray transform restricted to polynomial curves
Spyridon Dendrinos,Betsy Stovall
Mathematics , 2011,
Abstract: We establish near-optimal mixed-norm estimates for the X-ray transform restricted to polynomial curves with a weight that is a power of the affine arclength. The bounds that we establish depend only on the spatial dimension and the degree of the polynomial. Some of our results are new even in the well-curved case.
Contemplating Design: Listening to Children’s Preferences about Classroom Design  [PDF]
Marilyn A. Read
Creative Education (CE) , 2010, DOI: 10.4236/ce.2010.12012
Abstract: This paper focuses on children’s responses about the design of two images of interior classroom environments. Chil-dren reported that key elements were circles, spheres, and windows in the low visual stimulation environment. In the high visual stimulation environment they identified activity materials and the decor as preferred elements in the space. Results from this study can be used by designers of child development centers to guide the design of the space to reflect one that incorporates children’s preferences for design.
Modeling Insecticide Resistance in Endemic Regions of Kenya  [PDF]
Josephine Wairimu, Marilyn Ronoh
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.76050
Abstract: In this study, we develop an SIS model for two types of mosquitoes, a traditional one and one that is resistant to IRS and ITNs. The resistant mosquito develops behavioral adaptation to control measures put in place to reduce their biting rate. They also bite early before dusk and later after dark when people are outside the houses and nets. We determine the effect of the two types of mosquitoes on malaria transmission in Kenya. The basic reproduction number R 0 is established as a sharp threshold that determines whether the disease dies out or persists in the population. Precisely, if R 0 ≤ 1, the disease-free equilibrium is globally asymptotically stable and the disease always dies out and if R 0 > 1, there exists a unique endemic equilibrium which is globally stable and the disease persists. The contribution of the two types of mosquitoes to the basic reproduction number and to the level of the endemic equilibrium is analyzed.
The Carter Cuff: A Preliminary Assessment of Its Effectiveness in Enhancing Upper Body Strength in People with Unilateral Amputation and Other Disabilities  [PDF]
Marilyn Mitchell, David I. Anderson
Open Journal of Therapy and Rehabilitation (OJTR) , 2017, DOI: 10.4236/ojtr.2017.54011
Abstract: Five participants with unilateral, upper extremity amputation were recruited from a convenience sample and participated in a supervised resistance training exercise program in their own local exercise facility using the Carter Cuff (Carter Medical Devices, LLC). The Carter Cuff is a relatively new assistive device that allows people with unilateral, upper extremity amputation and other disabilities or injuries of the hand to engage in resistance training exercises. Following a six weeks training period, an online survey was made available to the participants who provided demographic information and answered questions about their exercise habits and their satisfaction with the ease of use and effectiveness of the Carter Cuff as well as its impact on their lives. The results of the survey provided preliminary support for the effectiveness of the Carter Cuff and its positive effects on people with amputations. Though more quantitative data on physiological and psychological measures are needed, these preliminary findings have important implications for occupational therapy practice.

Breast Cancer Research , 2011, DOI: 10.1186/bcr3057
Abstract: We genotyped 21 SNPs in 708 women with contralateral breast cancer and 1394 women with unilateral breast cancer who serve as the cases and controls in the Women's Environment, Cancer and Radiation Epidemiology (WECARE) Study. Records of treatment and ER status were available for most of WECARE Study participants. Associations of SNP genotypes and risk for contralateral breast cancer were calculated with multivariable adjusted conditional logistic regression methods.Multiple SNPs in the FGFR2 locus were significantly associated with contralateral breast cancer, including rs1219648 (per allele rate ratio (RR) = 1.25, 95%CI = 1.08-1.45). Statistically significant associations with contralateral breast cancer were also observed at rs7313833, near the PTHLH gene (per allele RR = 1.26, 95%CI = 1.08-1.47), rs13387042 (2q35) (per allele RR = 1.19, 95%CI = 1.02-1.37), rs13281615 (8q24) (per allele RR = 1.21, 95%CI = 1.04-1.40), and rs11235127 near TMEM135 (per allele RR = 1.26, 95%CI = 1.04-1.53). The A allele of rs13387042 (2q35) was significantly associated with contralateral breast cancer in ER negative first tumors while the A allele of rs11235127 (near TMEM135) was significantly associated with contralateral breast cancer in ER positive first tumors. Although some SNP genotypes appeared to modify contralateral breast cancer risk with respect to tamoxifen treatment or particular radiation doses, trend tests for such effects were not significant.Our results indicate that some common risk variants associated with primary breast cancer also increase risk for contralateral breast cancer, and that these risks vary with the ER status of the first tumor.Patients with breast cancer are two to five times more likely to develop a second primary cancer in the contralateral breast than are unaffected women to develop an initial breast cancer [1-4]. Established risk factors for asynchronous second primary contralateral breast cancer (CBC) include those suggesting a genetic basis, suc
Study design: Evaluating gene–environment interactions in the etiology of breast cancer – the WECARE study

Breast Cancer Research , 2004, DOI: 10.1186/bcr771
Abstract: To examine the joint roles of radiation exposure and genetic susceptibility in the etiology of breast cancer, we designed a case-control study nested within five population-based cancer registries. We hypothesized that a woman carrying a mutant allele in one of these genes is more susceptible to radiation-induced breast cancer than is a non-carrier. In our study, 700 women with asynchronous bilateral breast cancer were individually matched to 1400 controls with unilateral breast cancer on date and age at diagnosis of the first breast cancer, race, and registry region, and counter-matched on radiation therapy. Each triplet comprised two women who received radiation therapy and one woman who did not. Radiation absorbed dose to the contralateral breast after initial treatment was estimated with a comprehensive dose reconstruction approach that included experimental measurements in anthropomorphic and water phantoms applying patient treatment parameters. Blood samples were collected from all participants for genetic analyses.Our study design improves the potential for detecting gene–environment interactions for diseases when both gene mutations and the environmental exposures of interest are rare in the general population. This is particularly applicable to the study of bilateral breast cancer because both radiation dose and genetic susceptibility have important etiologic roles, possibly by interactive mechanisms. By using counter-matching, we optimized the informativeness of the collected dosimetry data by increasing the variability of radiation dose within the case–control sets and enhanced our ability to detect radiation–genotype interactions.The WECARE (for Women's Environmental Cancer and Radiation Epidemiology) Study is a multi-center, population-based case-control study of breast cancer designed to examine the interaction of gene carrier status and radiation exposure in the etiology of breast cancer. We are currently focusing on three major breast cancer suscepti
A Antropologia e o advento da Fertiliza??o In Vitro no Reino Unido: uma história curta
Strathern, Marilyn;
Cadernos Pagu , 2009, DOI: 10.1590/S0104-83332009000200002
Abstract: the year 2009 marked the 40th anniversary of a ground-breaking paper that appeared in the uk journal nature that presaged the advent of successful ivf procedures, and much else. this was the subject of a conference held under the title "in vitro human embryos: interdisciplinary reflections on the first four decades". my paper was simply called "the view from social anthropology", the basic "work" of the paper being in the accompanying bibliography. it concerns developments in the english-speaking world, but hopefully is of wider interest.
Novas formas econ?micas: um relato das terras altas da Papua-Nova Guiné
Strathern, Marilyn;
Mana , 1998, DOI: 10.1590/S0104-93131998000100005
Abstract: if inflation in a commodity economy implies a readjustment in the ratio of goods and money, then inflation in a gift economy must imply a readjustment in the rate by which relationships are produced. this article considers changes in the new guinea highlands over the last 30 years, and how one might interpret the manner in which certain relatioships are evolving. these are relations between clans, among kin and across the sexes. while the article considers three time horizonts over this period, it is deliberately written from the perspective of how the present (1990's) looks from the past (1960's).
