Geographical variation of cerebrovascular disease in New York State: the correlation with income

BACKGROUND: Income is known to be associated with cerebrovascular disease; however, little is known about the more detailed relationship between cerebrovascular disease and income. We examined the hypothesis that the geographical distribution of cerebrovascular disease in New York State may be predicted by a nonlinear model using income as a surrogate socioeconomic risk factor. RESULTS: We used spatial clustering methods to identify areas with high and low prevalence of cerebrovascular disease at the ZIP code level after smoothing rates and correcting for edge effects; geographic locations of high and low clusters of cerebrovascular disease in New York State were identified with and without income adjustment. To examine effects of income, we calculated the excess number of cases using a non-linear regression with cerebrovascular disease rates taken as the dependent variable and income and income squared taken as independent variables. The resulting regression equation was: excess rate = 32.075 - 1.22*10(-4)(income) + 8.068*10(-10)(income(2)), and both income and income squared variables were significant at the 0.01 level. When income was included as a covariate in the non-linear regression, the number and size of clusters of high cerebrovascular disease prevalence decreased. Some 87 ZIP codes exceeded the critical value of the local statistic yielding a relative risk of 1.2. The majority of low cerebrovascular disease prevalence geographic clusters disappeared when the non-linear income effect was included. For linear regression, the excess rate of cerebrovascular disease falls with income; each $10,000 increase in median income of each ZIP code resulted in an average reduction of 3.83 observed cases. The significant nonlinear effect indicates a lessening of this income effect with increasing income. CONCLUSION: Income is a non-linear predictor of excess cerebrovascular disease rates, with both low and high observed cerebrovascular disease rate areas associated with higher income. Income alone explains a significant amount of the geographical variance in cerebrovascular disease across New York State since both high and low clusters of cerebrovascular disease dissipate or disappear with income adjustment. Geographical modeling, including non-linear effects of income, may allow for better identification of other non-traditional risk factors

Bicovariant Differential Geometry of the Quantum Group SLh(2)SL_h(2)

There are only two quantum group structures on the space of two by two unimodular matrices, these are the $SL_q(2)$ and the $SL_h(2)$ [9-13] quantum groups. One can not construct a differential geometry on $SL_q(2)$, which at the same time is bicovariant, has three generators, and satisfies the Liebnitz rule. We show that such a differential geometry exists for the quantum group $SL_h(2)$ and derive all of its properties

Conversational correlates of children's acquisition of mental verbs and a theory of mind

The purpose of this study was to conduct a detailed examination of the ways mothers use mental verbs in conversations with three- and four-year-old children, and to link these usages to the children's developing understanding of mental verbs and a theory of mind. Sixty three- and four-year-olds, either attending preschool (PS) or not (NPS) were given tasks assessing mental verb distinctions and false belief. Their mothers' mental verb use was coded for (a) frequency, (b) type of utterance, (c) type of subordinate clause, (d) the person of the subject of the verb, and (e) the certainty of think. Within the three-year-olds, the NPS children performed significantly better on the mental verb comprehension task; moreover, compared to the PS mothers, the NPS mothers were found to use: (1) less statements and more questions, (2) less first person utterances and more second person utterances, and (3) think in its `very certain' form less often. In regression analyses, children's mental verb and false belief performance were positively predicted by maternal mental verb 1) questions, and 2) single clause utterances; the children's performance was negatively predicted by statements. These findings indicate how maternal input has the potential to promote or hinder children's understanding of the mind.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Fuzzy sphere bimodule, ABS construction to the exact soliton solutions

In this paper, we set up the bi-module of the algebra ${\cal A}$ on fuzzy sphere. Based on the differential operators in moving frame, we generalize the ABS construction into fuzzy sphere case. The applications of ABS construction are investigated in various physical systems.Comment: Latex file without figure, 13 page

Creative and Stylistic Devices Employed by Children During a Storybook Narrative Task: A Cross-Cultural Study

Purpose: The purpose of this study was to analyze the effects of culture on the creative and stylistic features children employ when producing narratives based on wordless picture books. Method: Participants included 60 first- and second-grade African American, Latino American, and Caucasian children. A subset of narratives based on wordless picture books collected as part of a larger study was coded and analyzed for the following creative and stylistic conventions: organizational style (topic centered, linear, cyclical), dialogue (direct, indirect), reference to character relationships (nature, naming, conduct), embellishment (fantasy, suspense, conflict), and paralinguistic devices (expressive sounds, exclamatory utterances). Results: Many similarities and differences between ethnic groups were found. No significant differences were found between ethnic groups in organizational style or use of paralinguistic devices. African American children included more fantasy in their stories, Latino children named their characters more often, and Caucasian children made more references to the nature of character relationships. Conclusion: Even within the context of a highly structured narrative task based on wordless picture books, culture influences children’s production of narratives. Enhanced understanding of narrative structure, creativity, and style is necessary to provide ecologically valid narrative assessment and intervention for children from diverse cultural backgrounds

Interspecific comparisons of C\u3csub\u3e3\u3c/sub\u3e turfgrass for tennis use: I. Wear tolerance and carrying capacity under actual match play

Previous studies in the evaluation of wear tolerance have been conducted using wear simulators. Research to investigate wear tolerance of C3 turfgrasses under actual playing conditions and their carrying capacity is limited. Three grass tennis courts (replicates) maintained as official size (single) courts were constructed. Eight species and cultivars were randomized within the three courts (blocks): (1) ‘Keeneland’ Kentucky bluegrass (KB, Poa pratensis L.), (2) ‘Rubix’ KB, (3) ‘Villa’ velvet bentgrass (VBG, Agrostis canina L.), (4) ‘Puritan’ colonial bentgrass (CL, Agrostis capillaris L.), (5) ‘007’ creeping bentgrass (CB, Agrostis stolonifera L.), (6) fine fescue (FF, Festuca spp.) mixture, (7) ‘Karma’ perennial ryegrass (PR, Lolium perenne L.), and (8) ‘Wicked’ PR. Injury at the baseline was measured by counting healthy grass on four dates in 2017 and 2019 using an intersect grid. Carrying capacity at the baseline was derived as hours of play to sustain 90, 80, 70, and 60% grass cover. After 6 wk of actual tennis play involving \u3e120 participating players in 2017 and 2019, KB and PR were superior to other C3 turfgrass for wear tolerance and carrying capacity. These two species exhibited four times the carrying capacity of FF species and nearly 60% more carrying capacity than bentgrass (BG) species. Species of BG afforded higher shoot density and better traction than KB and PR, with VBG exhibiting the best traction, and FF and PR exhibiting the poorest traction. In 2017, greater cell wall content increased wear tolerance and carrying capacity. Velvet bentgrass was as good as KB and PR in overall wear tolerance and carrying capacity under actual match play
