    Computing the Goodwillie-Taylor tower for discrete modules

    No full text
    A functor from finite sets to chain complexes is called atomic if it is completely determined by its value on a particular set. We present a new resolution for these atomic functors, which allows us to easily compute their Goodwillie polynomial approximations. By a rank filtration, any functor from finite sets to chain complexes is built from atomic functors. Computing the linear approximation of an atomic functor is a classic result involving partition complexes. Robinson constructed a bicomplex, which can be used to compute the linear approximation of any functor. We hope to use our new resolution to similarly construct bicomplexes that allow us to compute polynomial approximations for any functor from finite sets to chain complexes.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-08-01The student, Amelia Tebbe, accepted the attached license on 2017-07-11 at 14:57.The student, Amelia Tebbe, submitted this Dissertation for approval on 2017-07-11 at 15:10.This Dissertation was approved for publication on 2017-07-11 at 15:51.DSpace SAF Submission Ingestion Package generated from Vireo submission #11402 on 2017-09-29 at 11:18:54Made available in DSpace on 2017-09-29T16:39:45Z (GMT).

    The Argument for Same-Sex Marriage (Debate)

    No full text
    Perry v. Schwarzenegger, in which a federal district court held California\u27s ban on same-sex marriages unconstitutional, is set for expedited review in the Ninth Circuit; many argue that the case will ultimately be decided by the Supreme Court. The arguments for and against the constitutionality of such statutes are thus at a fever pitch. In an article published earlier this year, Professors Nelson Tebbe and Deborah Widiss argued that marriage rights are best conceived of as an issue of equal access, rather than one of equal protection or substantive due process. Nelson Tebbe & Deborah A. Widiss, Equal Access and the Right to Many, 158 U. PA. L. REV. 1375, 1377 (2010). In The Argument for Same-Sex Marriage, Professors Tebbe and Widiss revisit the arguments they made in Equal Access and the Right to Mary and emphasize their belief that distinguishing between different-sex marriage and same-sex marriage is inappropriate. They lament the sustained emphasis on the equal-protection and substantive-due-process challenges in the Perry litigation and suggest that an equal-access approach is more likely to be successful on appeal. Professor Shannon Gilreath questions some of the fundamental premises for same-sex marriage in Arguing Against Arguing for Marriage. He challenges proponents to truly reflect on what there is to commend marriage to Gay people, and points to his own reversal on the question as evidence. Though he stands fully in opposition to critics of same-sex marriage who use the stance to veil attacks on equality generally, Gilreath argues that marriage can be seen as a further institutionalization of gays and lesbians that risks assimilationist erasure of Gay identity. Gilreath concludes by noting that to the extent that marriage is assumed to be normatively good, the Tebbe-Widiss equal access approach to same-sex marriage recognition may be the most successful; still, he invites those on all sides of the debate to vigorously challenge that assumption

    Prevalence of microalbuminuria and its associated cardiovascular risk: German and Swiss results of the recent global i-SEARCH survey

    No full text
    QUESTION UNDER STUDY: The aim of this study was to determine the prevalence of microalbuminuria (MAU) in hypertensive patients attending an office or hospital based cardiologist or internist. An additional aim was to describe associations between MAU and cardiovascular risk factors as well as to investigate the role of pharmacotherapy. METHODS: International, observational, cross-sectional study of 22282 patients with 5605 attendees in Germany and Switzerland at 444 cardiology centers. Inclusion criteria were male and female outpatients, aged > or =18 years with currently treated or newly diagnosed hypertension (> or =140/90 mm Hg at rest on the day of the study visit) and no reasons for false positive dip stick tests. The main outcome measures were the prevalence of MAU, co-morbid cardiovascular risk factors or disease and their association with the presence of MAU, and the role of pharmacotherapy in modulating prevalence of MAU. RESULTS: Prevalence of MAU in Germany and Switzerland (53.1%) was high, but lower when compared to the prevalence in "other countries" (OC, 60.2%). Routine MAU measurement was performed in 52.9% of the practices only (32.9% OC), although physicians regarded MAU to be important for risk assessment and therapeutic decisions. MAU is highly correlated with a wide variety of cardiovascular risk factors and co-morbid cardiovascular conditions including high waist circumference (55.1% [95%CI 56.0; 59.7]), diabetes (59.1% [56.8; 61.3]), atrial fibrillation (62.3% [57.4; 66.9]) and peripheral arterial disease (67.1% [61.6; 72.2]). Angiotensin receptor blockers (ARBs) appeared to be associated with the lowest risk of MAU (52.1%). Calcium channel blockers (CCBs) were used more frequent in patients with MAU (28.7%) than without (23.4%). CONCLUSIONS: Patients with MAU are common in clinical cardiology and its presence is associated with a wide variety of cardiovascular risk factors and co-morbid cardiovascular conditions. A more aggressive multi-factorial treatment might help to reduce this risk constellation
