No full textMemorandum of understanding from Fred J. Haller to Block Manager regarding new process for baby formula at Heart Mountain incarceration camp.The Japanese American Archival Collection documents the people, places, and daily life of Japanese Americans, primarily those who lived in the once thriving community of pre-war Florin in the Sacramento region, as well as the conditions in American incarceration camps during World War II. The approximately 7,000 original items include personal and official letters, photographs, diaries, arts and crafts, newsletters, textiles, camps artifacts, yearbooks and other publications
The Felix: An Island Tale
No full textThis paperback book of 149 pages is in the same format as Fables from an Island by the same author from 1981. It was available on eBay at the same time and promoted as fables from an island. I have read the prologue and first chapter and found them involving. I want to go on with this book about a handsome young islander who went off to World War II and came back mentally and physically damaged. The title page is signed by J. Stella Sonier. While there are no fables here, this book is a valuable complement to the earlier book by Sonier. And I hope it will find another reader--like me--sometime in the future.Signed by J. Stella SonierJ.

A survey of blockholders and corporate control
No full textThe author surveys the empirical literature on large-percentage shareholders in public corporations, focusing on four key issues: the prevalence of blockholders; the motivation for block ownership; the effect of blockholders on executive compensation, leverage, the incidence of takeovers, and a wide range of corporate decisions; and the effect of blockholders on firm value. A central finding of this study is that there is little reason for policymakers or small investors to fear large-percentage shareholders in general, especially when the blockholders are active in firm management.Stockholders ; Corporate governance
Additive block diagonal preconditioning for block two-by-two linear systems of skew-Hamiltonian coefficient matrices
No full textFor a class of block two-by-two systems of linear equations with certain skew-Hamiltonian coefficient matrices, we construct additive block diagonal preconditioning matrices and discuss the eigen-properties of the corresponding preconditioned matrices. The additive block diagonal preconditioners can be employed to accelerate the convergence rates of Krylov subspace iteration methods such as MINRES and GMRES. Numerical experiments show that MINRES preconditioned by the exact and the inexact additive block diagonal preconditioners are effective, robust and scalable solvers for the block two-by-two linear systems arising from the Galerkin finite-element discretizations of a class of distributed control problems
Block Graphs in Practice
No full textMotivated by the rapidly increasing size of genomic databases, code repositories and versioned texts, several compression schemes have been proposed that work well on highly-repetitive strings and also support fast random access: e.g., LZ-End, RLZ, GDC, augmented SLPs, and block graphs. Block graphs have good worst-case bounds but it has been an open question whether they are practical. We describe an implementation of block graphs that, for several standard datasets, provides better compression and faster random access than competing schemes.Peer reviewe
Inducing Fe moment in LaFeSi with p-block element substitution
No full textWe studied the LaFeSi phase using density functional theory based full-potential linearized augmented plane wave (FP-LAPW) method. Specifically we examined the effect of p-element substitution on the stability and magnetic properties focusing on pathways to induce Fe magnetic moments. We demonstrate that either partial or complete substitutions at the Si 2 c-site by several p-block elements lead to non-zero Fe moments. Our theoretical study shows that partially substituted LaFeSi 1-y Ga y and LaFeSi 1-y Al y are more thermodynamically stable than the fully substituted LaFeGa and LaFeAl. We also found that the P substitutions, either partial or complete, have the most negative formation energies, however the compounds containing phosphorus are non-magnetic. Our work highlights a pathway toward manipulations of the otherwise quenched Fe-moments in LaFeSi-related compounds and help in advancing the potential magnetic functionalities of LaFeX compounds.This article is published as Chouhan, Rajiv K., Tyler J.

Professional Development for New Middle School Teachers to Use Constructivist Pedagogy in the Block Period
No full textIn the 1980s and 1990s, publications like A Nation at Risk and Prisoners of Time were highly critical of the American public school system. In response, school administrators reviewed their master schedules to evaluate how time was scheduled and the majority of them chose block scheduling to secure longer, uninterrupted periods of instructional time. Upon implementing block scheduling, schools noted a need for a change in pedagogy. Constructivist teaching, shown to be effective with multiple ages, has become a preferred pedagogy for elementary and middle school teachers during a block period. The review of literature includes a description of the forces behind block scheduling and provides a background of constructivist theory and teaching practices based on the writings of Jean Piaget and Lev Vygotsky. Combining constructivist teaching with block scheduling creates an environment conducive to young adolescent learning; however, properly preparing teachers through professional development is key to effective implementation. The purpose of this action research study was to facilitate the professional growth of new teachers by providing job embedded professional development opportunities that were grounded in constructivist practices and demonstrated to be effective with young adolescent learners while teaching in a block period.Ed.

Nested row-column designs for near-factorial experiments with two treatment factors and one control treatment
No full textThe authors also thank Queen Mary, University of London, the University of St Andrews and the Poznan University of Life Sciences for financial support. The second author was also supported by the British-Polish Young Scientists Programme, grant WAR/342/116.This paper presents some methods of designing experiments in a block design with nested rows and columns. The treatments consist of all combinations of levels of two treatment factors, with an additional control treatment.Peer reviewe

How can potatoes be smartly cultivated with biochar as a soil nutrient amendment technique in Atlantic Canada?
No full textThe question if biochar is a suitable soil nutrient amendment for potato cultivation in the Atlantic Canada is yet to be answered. The objective of this study was to answer this question. Three replicates of twelve lysimeters, each 8000 cm2, were packed with an Atlantic Canada representative soil to cultivate potatoes with four treatments of soil amendments (T1 = control [no added nutrients], T2 = B [biochar], T3 = F [synthetic fertilizer @ recommended NPK], and T4 = B + F [biochar + recommended NPK]) under a completely randomized block design with factorial arrangements. Chemical analyses of soils were conducted for physical, hydrological, and chemical (including concentration of macro- and micro-nutrients) prior to and after the completion experiments to evaluate soil fertility and its resulting effects on crop yield. The biochar amendment improved soil micro- and macro-nutrients. Soil organic matter, pH, and cation exchange capacity (ECE) significantly increased by application of biochar. The maximum potato yield of 30,467.4 kg h−1 was achieved by the combined application of biochar and synthetic fertilizer as this combination resulted in the maximum net benefit (– 2621.49 ha−1. It is therefore concluded that biochar amendment of soils resembling to that of the Atlantic Canada representative soil used in this study, with a mix of recommended NPK for, can formulate a smart precision farming nutrient management technique for this region subject to the field trials and replicate experimental treatments for more than three times
