Variations of Hodge Structure Considered as an Exterior Differential System: Old and New Results

This paper is a survey of the subject of variations of Hodge structure (VHS) considered as exterior differential systems (EDS). We review developments over the last twenty-six years, with an emphasis on some key examples. In the penultimate section we present some new results on the characteristic cohomology of a homogeneous Pfaffian system. In the last section we discuss how the integrability conditions of an EDS affect the expected dimension of an integral submanifold. The paper ends with some speculation on EDS and Hodge conjecture for Calabi-Yau manifolds

Extremal degenerations of polarized Hodge structures

We describe a Hodge theoretic approach to the question: In what ways can a smooth projective variety degenerate?Comment: v.2 (typos corrected), comments welcom

The child, the text and the teacher: reading primers and reading instruction

From the late sixteenth century, in response to the problem of how best to teach children to read, a variety of texts such as primers, spellers and readers were produced in England for vernacular instruction. This paper describes how these materials were used by teachers to develop first, a specific religious understanding according to the stricture of the time and second, a moral reading practice that provided the child with a guide to secular conduct. The analysis focuses on the use of these texts as a productive means for shaping the child-reader in the context of newly emerging educational spaces which fostered a particular, morally formative relation among teacher, child and text

Period Mappings and Ampleness of the Hodge line bundle

We discuss progress towards a conjectural Hodge theoretic completion of a period map. The completion is defined, and we conjecture that it admits the structure of a compact complex analytic variety. The conjecture is proved when the image of the period map has dimension 1,2. Assuming the conjecture holds, we then prove that the augmented Hodge line bundle extends to an ample line bundle on the completion. In particular, the completion is a projective algebraic variety that compactifies the image, analogous to the Satake-Baily-Borel compactification.Comment: 62 pages. v2 significant revision of the initial submission (v1); v3 further improvements and new references adde

Military Millennials As Next Generation Leaders: Do Leadership Traits Matter?

Employers are constantly evaluating individuals to fill leadership roles within their organizations to extract the highest return from their resources and investments. Millennials, born between 1982 and 2000 (Howe and Strauss, 2000), represent the youngest and newest generation entering the workforce. A sub-population of this generation consists of military veterans returning to the United States after the wars in Iraq and Afghanistan. This quantitative study examines the leadership traits of the military Millennials that have transitioned to civilian life and compares this population segment with Millennials without a military background. To compare the two groups of the generational cohort, a survey comprised of 14 leadership traits derived from the Leadership Trait Questionnaire (LTQ) (Northouse, 2010) and 9 demographic and characteristic questions was utilized in this study. The researcher distributed the survey online to 150 potential participants. A total of 53 surveys were completed online, resulting in a response rate of 35.3 %. Among the participating respondents, 43% were military Millennials and 57% were non-Military Millennials with 28.6 years as the average age. There were 52.8% males, and 47.2% females among respondents. The results from the nonparametric Mann-Whitney (M-W) U test indicated a statistical significance for the leadership trait of self-assurance for the military Millennials. The leadership traits of trustworthy and dependable ranked highest for the military Millennials and non-military Millennials, with each of the two traits slightly higher for the military Millennials. The analysis revealed no statistical significance among demographic and characteristic data. The findings indicated the need for additional research on military Millennials and leadership and future research on intra-generational analysis of Millennials and leadership traits

Evidence for Classical Projection or Experimental Artifact: A Failure to Replicate

Classical, or Freudian projection is a concept which has been widely accepted by psychiatrists and clinical psychologists despite the lack of conclusive empirical evidence supporting its existence. A recent study using the psychodynamic activation technique resulted in evidence which would support classical projection. The present study utilized the same psychodynamic activation procedure using slightly different stimuli. This study resulted in evidence which would not support the concept of classical projection
