Spin Matrix for the Scaled Periodic Ising Model

The matrix elements of the spin operator for the periodic Ising model in a basis of eigenvectors for the transfer matrix are calculated in the massive scaling limit

Youth Homelessness

CCH estimates that, over the course of a year, more than 25,000 youth in Illinois experience homelessness. Homeless youth are between the ages of 14 and 21 who have left home because of serious family problems, are not in a safe and stable living situation, and cannot be reunited with their families

Hōmai te Waiora ki Ahau: te ara whakamua - towards the establishment of construct validity

Hōmai te Waiora ki Ahau: te ara whakamua, is about the development of a tool to measure psychological wellbeing among Māori. Why is it relevant? Because a quick look at the June 2002 edition of New Zealand’s Journal of Psychology will show you that the wellbeing measures being used in this country are not responsive to the needs of Māori, are not based on Māori concepts or Constructs, do not facilitate Māori participation in te ao Māori and do not provide pathways through which Māori can develop a positive Māori identity. It is highly unlikely that the tools which psychologists use to measure wellbeing among Māori will help Māori to experience whānau ora and that, as we all know, is the paramount health objective for Māori (Ministry of Health, 2002). In this regard, it would seem that the powers that be in psychology are failing to meet their Treaty obligations to Māori. Therefore, Hōmai te Waiora ki Ahau simply aims to assist change. This presentation will briefly describe the context of the development of this measure, the methodologies used to develop this tool, the outcomes of a small pilot-study, and current challenges and future directions for Hōmai te Waiora ki Ahau

Tenure reform and presidential power: The single, six-year term proposal"

During the twentieth century, a series of rapid changes transformed the office of the presidency, affecting not only its raw power and influence upon other political institutions but also, crucially for an office defined as much by image as by constitutional authority, its status in the eyes of the American public and news media. From the turn-of-the-century administration of Theodore Roosevelt to the Lyndon Johnson presidency in the 1960s, George Reedy notes, “commitment to the presidential concept” by politicians, voters and the news media became so pronounced that Americans were "virtually incapable of thinking of the United States in other terms."1 Progressives frequently encouraged the trend toward greater presidential influence as a useful means of bypassing entrenched conservatism in national and state legislatures but many on the political right were disturbed by the expansion of executive power, viewing it as both cause and consequence of liberal interventionism and as a threat to the equilibrium of constitutional government

Tau functions for the Dirac operator on the cylinder

The goal of the present paper is to calculate the determinant of the Dirac operator with a mass in the cylindrical geometry. The domain of this operator consists of functions that realize a unitary one-dimensional representation of the fundamental group of the cylinder with $n$ marked points. The determinant represents a version of the isomonodromic $\tau$-function, itroduced by M. Sato, T. Miwa and M. Jimbo. It is calculated by comparison of two sections of the $\mathrm{det}^*$-bundle over an infinite-dimensional grassmannian. The latter is composed of the spaces of boundary values of some local solutions to Dirac equation. The principal ingredients of the computation are the formulae for the Green function of the singular Dirac operator and for the so-called canonical basis of global solutions on the 1-punctured cylinder. We also derive a set of deformation equations satisfied by the expansion coefficients of the canonical basis in the general case and find a more explicit expression for the $\tau$-function in the simplest case $n=2$.Comment: 32 pages, 5 figure
