nidottu
A How-To Guide for Conducting Common Fisheries-Related Analyses in RIntroductory Fisheries Analyses with R provides detailed instructions on performing basic fisheries stock assessment analyses in the R environment. Accessible to practicing fisheries scientists as well as advanced undergraduate and graduate students, the book demonstrates the flexibility and power of R, offers insight into the reproducibility of script-based analyses, and shows how the use of R leads to more efficient and productive work in fisheries science.The first three chapters present a minimal introduction to the R environment that builds a foundation for the fisheries-specific analyses in the remainder of the book. These chapters help you become familiar with R for basic fisheries analyses and graphics.Subsequent chapters focus on methods to analyze age comparisons, age-length keys, size structure, weight-length relationships, condition, abundance (from capture-recapture and depletion data), mortality rates, individual growth, and the stock-recruit relationship. The fundamental statistical methods of linear regression, analysis of variance (ANOVA), and nonlinear regression are demonstrated within the contexts of these common fisheries analyses. For each analysis, the author completely explains the R functions and provides sufficient background information so that you can confidently implement each method.Web Resource The author’s website at http://derekogle.com/IFAR/ includes the data files and R code for each chapter, enabling you to reproduce the results in the book as well as create your own scripts. The site also offers supplemental code for more advanced analyses and practice exercises for every chapter.

Dive into The Instructor, former Army intelligence officer T. R. Hendricks' fast paced, action-packed debut thriller that's Jack Reacher meets Survivorman, the first novel in the Derek Harrington series "Packed with action, tension, and humanity, The Instructor delivers." --Mark Greaney, #1 New York Times bestselling author of Burner, a Gray Man Novel Derek Harrington, retired Marine Force Recon and SERE instructor, is barely scraping by teaching the basics of wilderness survival. His fledgling bushcraft school is on the cusp of going out of business and expenses are piling up fast. His only true mission these days? To get his ailing father into a full care facility and to support his ex-wife and their son. When one of his students presents him with an opportunity too good to be true--$20,000 to instruct a private group for 30 days in upstate New York--Derek reluctantly takes the job, despite his reservations about the group's insistence on anonymity. But it isn't long before the training takes an unexpected turn--and a new offer is made. Reaching out to an FBI contact to sound his concerns, Derek soon finds himself in deep cover, deep in the woods, embroiled with a fringe group led by a charismatic leader who will stop at nothing to get what he wants. When what he wants becomes Derek's head, the teacher is pitted against his students as Derek races against time to stop what could very well be the first attack by the domestic terrorist cell. "A pulse-pounding thriller. . . Hendricks delivers on all cylinders " --Simon Gervais, former RCMP counterterrorism officer and bestselling author of The Last Protector

Principal Component and Correspondence Analyses Using R

Principal Component and Correspondence Analyses Using R

Herve Abdi; Derek Beaton

Springer International Publishing AG
2025
nidottu
With the right R packages, R is uniquely suited to perform Principal Component Analysis (PCA), Correspondence Analysis (CA), Multiple Correspondence Analysis (MCA), and metric multidimensional scaling (MMDS). The analyses depicted in this book use several packages specially developed for theses analyses and include (among others): the ExPosition suite, FactoMiner , ade4, and ca. The authors present each technique with one or several small examples that demonstrate how to enter the data, perform the standard analyses, and obtain professional quality graphics. Through explanations of the major options for how to carry out each method, readers can tailor the content of this book to their particular goals. Explanations include the effects of using particular packages. ExPosition is a great choice for the methods as it was written specifically for this book. However, options abound and are illustrated within unique scenarios. The first chapter includes installation of the packages. At the end of the book, a short appendix presents critical mathematical material for readers who want to go deeper into the theory.

Half a Century of Free Radical Chemistry

Half a Century of Free Radical Chemistry

Derek H. R. Barton; Shyamal I. Parekh

Cambridge University Press
1993
pokkari
This book describes the experience over 25 years of the senior author with the chemistry of organic free radicals. It begins with a mechanistic study of industrial importance on the pyrolysis of chlorinated alkanes. It continues with a theory on the biosynthesis of phenolate derived alkaloids involving phenolate radical coupling. There follows 20 years of practical work to prove the theory correct, especially in the case of morphine alkaloids. The book then describes the work on nitrile photolysis (Barton reaction) which involved the invention of new radical chemistry leading to a simple synthesis of the important hormone, aldosterone. There follows a description of the invention of an important new method for the deoxygenation of biologically important molecules, especially sugars and nucleosides, using radical chemistry applied to thiocarbonyl derivatives. Some years later, in a logical extension to carboxylic acids, another new reaction was invented which provides carbon, nitrogen, oxygen and other radicals under mild conditions. A final chapter summarizes recent applications of thiocarbonyl group derived radical reactions by other authors.

Russian Political Institutions

Russian Political Institutions

Derek J. R. Scott

TAYLOR FRANCIS LTD
2024
sidottu
First published in 1958, Russian Political Institutions is intended primarily to meet the need of university students for a good account of the political institutions of the Soviet Union in terms similar to those used in their study of other countries. Though the unique comprehensiveness of the Soviet state’s concerns, to which the book draws attention, precludes a formally comparative approach, the ways in which its business is done can be explained, as elsewhere, by the country’s circumstances and historical experience.The first chapter indicates something of these circumstances and experience and of the motives of the Soviet state. The second explains the way the distinctive institutional form of the Soviet state came into being and the process by which it assumed some of the conventional state machinery. The third examines this conventional state and its unconventional functions in a Russian Communist setting. The fourth concerns the structure and operation of the complex device called the Party. The fifth, in turn, examines the means evolved for the fulfillment of the state’s main task, the management of the fully nationalized economy as a single concern, and the other main systems of control, including the judicial system. The sixth chapter suggests briefly how priorities of tasks are decided upon, obligations determined, and their performance secured. This is a must read for students and scholars of Russian history and Soviet politics.

A Descriptive Catalogue of the English Manuscripts of John Gower's Confessio Amantis

A Descriptive Catalogue of the English Manuscripts of John Gower's Confessio Amantis

Derek Pearsall; Linne R Mooney

D.S. Brewer
2021
sidottu
Winner of the 2022 John Hurt Fisher Award from the John Gower Society First comprehensive catalogue of the manuscripts of one of the most important medieval works, with full descriptions of their features. The Confessio Amantis is John Gower's major work in English, written around the time that his acquaintance Geoffrey Chaucer was writing the Canterbury Tales. Extant manuscripts are numerous. At the end of the nineteenth century G. C. Macaulay had described the forty manuscripts then known to survive in the introduction to his edition, but some of these descriptions were very brief, and of course the other nine of whose existence he was then unaware were not included. This descriptive catalogue of all of the surviving manuscripts containing the Confessio is the first work to bring together extensive detailed descriptions of its forty-nine complete manuscripts and numerous fragments and excerpts; it will enable scholars of Middle English literature and manuscript studies to compare features across the corpus of surviving manuscripts or read detailed descriptions of individual manuscripts. Each description in this catalogue covers the manuscript's contents, artwork, physical qualities such as size, material, collation, foliation, etc., as well as additions by later users and provenance. There is also a lengthy introduction giving an overview of the corpus, and appendices for reference to the current whereabouts of the manuscripts, fragments and excerpts, and listing Gower's Latin and French works that appear in some of the manuscripts. Eight colour illustrations provide context for discussions of the miniatures and illuminated borders of some manuscripts.

The Klansman’s Son

The Klansman’s Son

R. Derek Black

ABRAMS
2024
sidottu
From the former heir-apparent to white nationalism, The Klansman’s Son is an astonishing memoir of a childhood built on fear, of breaking from a community of hate. When coded language and creeping authoritarianism spread the ideas of white nationalists, this is an essential book with a powerful voice. Derek Black was raised to take over the white nationalist movement in the United States. Their father, Don Black, was a former Grand Wizard in the Ku Klux Klan and started Stormfront, the internet’s first white supremacist website—Derek built the kids’ page. David Duke, was also their close family friend and mentor. Racist hatred, though often wrapped up in respectability, was all Derek knew. Then, while in college in 2013, Derek publicly renounced white nationalism and apologized for their actions and the suffering that they had caused. The majority of their family stopped speaking to them, and they disappeared into academia, convinced that they had done so much harm that there was no place for them in public life. But in 2016, as they watched the rise of Donald Trump, they immediately recognized what they were hearing—the spread and mainstreaming of the hate they had helped cultivate—and they knew that they couldn’t stay silent. This is a thoughtful, insightful, and moving account of a singular life, with important lessons for our troubled times. Derek can trace a uniquely insider account of the rise of white nationalism, and how a child indoctrinated with hate can become an anti-racist adult. Few understand the ideology, motivations, or tactics of the white nationalist movement like Derek, and few have ever made so profound a change.

Toward a Long-term Strategy for Assuring Access in Key Strategic Regions

How does the Army plan to ensure its continued access to potential trouble spots around the world? The authors developed scenarios and conducted political-military games to determine what strategies, tactics, and capabilities potential adversaries might use to complicate U.S. access to key areas and how effective the U.S. counters to these tactics are. They were sanguine about the ability of the U.S. to prevail in the short-term but also identified several conc erns and suggested areas of improvement, including expanding the number of in-theater bases that might be available; enhancing the flexibility and deployability of U.S. forces to more austere bases; and upgrading detection, warning, and force protection measures.

Lopes: The English in Portugal 1383-1387

Lopes: The English in Portugal 1383-1387

Derek W. Lomax; R. J. Oakley

Aris Phillips Ltd
1988
sidottu
It is astonishing that this is the first English translation of these Chronicles , as they are undoubtably amongst the finest produced in the Middle Ages and treat an important episode in the Hundred Years War. Lopes' mastery of dramatic narrative and picturesque description, so ably captured in this translation, found a fit subject in the foreign interventions and the revolutionary changes that took place in the second half of the 14th century in Portugal. What makes Lopes virtually unique as an historian of that date is his insistence on the use of documentary sources as he explains in his prologue to The Chronicle of Dom Joao , something that he as the keeper of the Royal archives was able to practice so effectively. It seems fitting that Fernao Lopes' great work should appear in a dual language edition as a tribute to the six hundred years alliance, whose beginning he so vividly recalls between the English and Portuguese peoples.

Suspect Citizens

Suspect Citizens

Frank R. Baumgartner; Derek A. Epp; Kelsey Shoub

Cambridge University Press
2018
sidottu
Suspect Citizens offers the most comprehensive look to date at the most common form of police-citizen interactions, the routine traffic stop. Throughout the war on crime, police agencies have used traffic stops to search drivers suspected of carrying contraband. From the beginning, police agencies made it clear that very large numbers of police stops would have to occur before an officer might interdict a significant drug shipment. Unstated in that calculation was that many Americans would be subjected to police investigations so that a small number of high-level offenders might be found. The key element in this strategy, which kept it hidden from widespread public scrutiny, was that middle-class white Americans were largely exempt from its consequences. Tracking these police practices down to the officer level, Suspect Citizens documents the extreme rarity of drug busts and reveals sustained and troubling disparities in how racial groups are treated.
