Thesis with Row Frequencies (RF) and Column Frequencies (CF)………………………...173 SAMPLING BIASES AND NEW WAYS OF ADDRESSING THE SIGNIFICANCE OF TRAUMA IN NEANDERTALS by Virginia Hutton Estabrook A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Anthropology) in The University of Michigan 2009 Doctoral Committee: Professor Milford H. Wolpoff, Chair Professor A. Roberto Frisancho Professor John D. Speth Associate Professor Thomas R. Gest Associate Professor Rachel Caspari, Central Michigan University © Virginia Hutton Estabrook 2009 To my father who read to me my first stories of prehistory ii ACKNOWLEDGEMENTS There are so many people whose generosity and inspiration made this dissertation possible. Chief among them is my husband, George Estabrook, who has been my constant cheerleader throughout this process. I would like to thank my committee for all of their help, insight, and time. I am truly fortunate in my extraordinary advisor and committee chair, Milford Wolpoff, who has guided me throughout my time here at Michigan with support, advice, and encouragement (and nudging). I am deeply indebted to Tom Gest, not only for being a cognate par excellence, but also for all of his help and attention in teaching me gross anatomy. Rachel Caspari, Roberto Frisancho, and John Speth gave me their attention for this dissertation and also offered me wonderful examples of academic competence, graciousness, and wit when I had the opportunity to take their classes and/or teach with them as their GSI. All photographs of the Krapina material, regardless of photographer, are presented with the permission of J. Radovčić and the Croatian Natural History Museum. My research would not have been possible without generous grants from Rackham, the International Institute, and the Department of Anthropology. Nor would it iii have been possible without the local hosting of Jakov and Davorka Radovčić in Zagreb and Eugenia Cunha and Paulo Gama Mota in Coimbra. Like every other Anthropology graduate student, I have accepted Laurie Marx as my personal savior and many very bad things would have happened were it not for her help. Finally, I would not have ever been involved in the field of Anthropology were it not for the inspiration and support of many people throughout my life. These include my grandfather with whom I collected “artifacts” from our beach before I ever set foot in a classroom, my parents who constantly provided me with opportunities to explore my interests, amazing high school teachers like Peter Perhonis and Charlie Flanagan who took me seriously, wonderful professors at Bryn Mawr like Rick Davis who convinced me that Anthropology was the most wonderful and fascinating major a person could have, Douglas Ubelaker who taught me osteology and pointed me towards issues of preservation and sampling biases in the analysis of trauma, Janet Monge whose mentorship and generosity has been incredibly important to me throughout my time as her student (which I will always be), my professors and fellow graduate students at Michigan who have been some of the smartest people I have ever met and whose company I have enjoyed and been constantly inspired by, especially Steve Pastner, whose wonderful drawing graces the frontispiece, Beverly Strassmann, Loring Brace, Andy Merriwether, Meghan Howey, Liz Bridges, Daphne Gallagher, Steven Dueppen, Kay Grennan, Anna Williams, and Theo Morrow, and, finally, my dear daughter, Elizabeth, whose smiles are my sunshine on the dark, cold and dreary Ann Arbor days. iv TABLE OF CONTENTS DEDICATION……………………………………………………………………..........ii ACKNOWLEDGEMENTS……..……………………………………………...............iii LIST OF FIGURES……………..……………………………………………………..viii LIST OF TABLES…...………………………………………………………………….ix LIST OF APPENDICES.....……………………..……………….………………….... xv ABSTRACT…………………………………………………………………………….xvi CHAPTER I.

    VIRGINIA LAW REVIEW ASSOCIATION VIRGINIA LAW REVIEW ONLINE VOLUME 103 DECEMBER 2017 94–102 ESSAY ACT-SAMPLING BIAS AND THE SHROUDING OF REPEAT OFFENDING Ian Ayres, Michael Chwe and Jessica Ladd∗ A college president needs to know how many sexual assaults on her campus are caused by repeat offenders. If repeat offenders are responsible for most sexual assaults, the institutional response should focus on identifying and removing perpetrators. But how many offenders are repeat offenders? Ideally, we would find all offenders and then see how many are repeat offenders. Short of this, we could observe a random sample of offenders. But in real life, we observe a sample of sexual assaults, not a sample of offenders. In this paper, we explain how drawing naive conclusions from “act sampling”—sampling people’s actions instead of sampling the population—can make us grossly underestimate the proportion of repeat actors. We call this “act-sampling bias.” This bias is especially severe when the sample of known acts is small, as in sexual assault, which is among the least likely of crimes to be reported.1 In general, act sampling can bias our conclusions in unexpected ways. For example, if we use act sampling to collect a set of people, and then these people truthfully report whether they are repeat actors, we can overestimate the proportion of repeat actors. * Ayres is the William K. Townsend Professor at Yale Law School; Chwe is Professor of Political Science at the University of California, Los Angeles; and Ladd is the Founder and CEO of Callisto. 1 David Cantor et al., Report on the AAU Campus Climate Survey on Sexual Assault and Sexual Misconduct, Westat, at iv (2015) [hereinafter AAU Survey], (noting that a relatively small percentage of the most serious offenses are reported) https://perma.cc/5BX7-GQPU; Nat’ Inst.

  • Upper Pleistocene Human Remains from Vindija Cave, Croatia, Yugoslavia
    AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY 54~499-545(1981) Upper Pleistocene Human Remains From Vindija Cave, Croatia, Yugoslavia MILFORD H. WOLPOFF, FRED H. SMITH, MIRKO MALEZ, JAKOV RADOVCIC, AND DARKO RUKAVINA Department of Anthropology, University of Michigan, Ann Arbor, Michigan 48109 (MH.W.1,Department of Anthropology, University of Tennessee, Kmxuille, Tennessee 37916 (FHS.),and Institute for Paleontology and Quaternary Geology, Yugoslav Academy of Sciences and Arts, 41000 Zagreb, Yugoslavia (M.M., J.R., D.R.) KEY WORDS Vindija, Neandertal, South Central Europe, Modern Homo sapiens origin, Evolution ABSTRACT Human remains excavated from Vindija cave include a large although fragmentary sample of late Mousterian-associated specimens and a few additional individuals from the overlying early Upper Paleolithic levels. The Mousterian-associated sample is similar to European Neandertals from other regions. Compared with earlier Neandertals from south central Europe, this sam- ple evinces evolutionary trends in the direction of Upper Paleolithic Europeans. Compared with the western European Neandertals, the same trends can be demon- strated, although the magnitude of difference is less, and there is a potential for confusing temporal with regional sources of variation. The early Upper Paleo- lithic-associated sample cannot be distinguished from the Mousterian-associated hominids. We believe that this site provides support for Hrdlicka’s “Neandertal phase” of human evolution, as it was originally applied in Europe. The Pannonian Basin and surrounding val- the earliest chronometrically dated Upper leys of south central Europe have yielded a Paleolithic-associated hominid in Europe large and significant series of Upper Pleisto- (Smith, 1976a). cene fossil hominids (e.g. Jelinek, 1969) as well This report presents a detailed comparative as extensive evidence of their cultural behavior description of a sample of fossil hominids re- (e.g.

D. Fallacy Duda ofand Online J. L. Nobile Surveys MARK DAMIAN DUDA AND JOANNE L. NOBILE Responsive Management, Harrisonburg, Virginia, USA Internet or online surveys have become attractive to fish and wildlife agencies as an economical way to measure constituents’ opinions and attitudes on a variety of issues. Online surveys, however, can have several drawbacks that affect the scientific validity of the data. We describe four basic problems that online surveys currently present to researchers and then discuss three research projects conducted in collaboration with state fish and wildlife agencies that illustrate these drawbacks. Each research project involved an online survey and/or a corresponding random telephone survey or non- response bias analysis. Systematic elimination of portions of the sample population in the online survey is demonstrated in each research project (i.e., the definition of bias). One research project involved a closed population, which enabled a direct comparison of telephone and online results with the total population. Keywords Internet surveys, sample validity, SLOP surveys, public opinion, non- response bias Introduction Fish and wildlife and outdoor recreation professionals use public opinion and attitude sur- veys to facilitate understanding their constituents. When the surveys are scientifically valid and unbiased, this information is useful for organizational planning. Survey research, however, costs money.

  • Levy, Marc A., “Sampling Bias Does Not Exaggerate Climate-Conflict Claims,” Nature Climate Change 8,6 (442)
    Levy, Marc A., “Sampling bias does not exaggerate climate-conflict claims,” Nature Climate Change 8,6 (442) https://doi.org/10.1038/s41558-018-0170-5 Final pre-publication text To the Editor – In a recent Letter, Adams et al1 argue that claims regarding climate-conflict links are overstated because of sampling bias. However, this conclusion rests on logical fallacies and conceptual misunderstanding. There is some sampling bias, but it does not have the claimed effect. Suggesting that a more representative literature would generate a lower estimate of climate- conflict links is a case of begging the question. It only make sense if one already accepts the conclusion that the links are overstated. Otherwise it is possible that more representative cases might lead to stronger estimates. In fact, correcting sampling bias generally does tend to increase effect estimates2,3. The authors’ claim that the literature’s disproportionate focus on Africa undermines sustainable development and climate adaptation rests on the same fallacy. What if the climate-conflict links are as strong as people think? It is far from obvious that acting as if they were not would somehow enhance development and adaptation. The authors offer no reasoning to support such a claim, and the notion that security and development are best addressed in concert is consistent with much political theory and practice4,5,6. Conceptually, the authors apply a curious kind of “piling on” perspective in which each new paper somehow ratchets up the consensus view of a country’s climate-conflict links, without regard to methods or findings. Consider the papers cited as examples of how selecting cases on the conflict variable exaggerates the link.

  • 10. Sample Bias, Bias of Selection and Double-Blind
    SEC 4 Page 1 of 8 10. SAMPLE BIAS, BIAS OF SELECTION AND DOUBLE-BLIND 10.1 SAMPLE BIAS: In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others. It results in abiased sample, a non-random sample[1] of a population (or non-human factors) in which all individuals, or instances, were not equally likely to have been selected.[2] If this is not accounted for, results can be erroneously attributed to the phenomenon under study rather than to the method of sampling. Medical sources sometimes refer to sampling bias as ascertainment bias.[3][4] Ascertainment bias has basically the same definition,[5][6] but is still sometimes classified as a separate type of bias Types of sampling bias Selection from a specific real area. For example, a survey of high school students to measure teenage use of illegal drugs will be a biased sample because it does not include home-schooled students or dropouts. A sample is also biased if certain members are underrepresented or overrepresented relative to others in the population. For example, a "man on the street" interview which selects people who walk by a certain location is going to have an overrepresentation of healthy individuals who are more likely to be out of the home than individuals with a chronic illness. This may be an extreme form of biased sampling, because certain members of the population are totally excluded from the sample (that is, they have zero probability of being selected).

  • Cognitive Biases in Software Engineering: a Systematic Mapping Study
    Cognitive Biases in Software Engineering: A Systematic Mapping Study Rahul Mohanani, Iflaah Salman, Burak Turhan, Member, IEEE, Pilar Rodriguez and Paul Ralph Abstract—One source of software project challenges and failures is the systematic errors introduced by human cognitive biases. Although extensively explored in cognitive psychology, investigations concerning cognitive biases have only recently gained popularity in software engineering research. This paper therefore systematically maps, aggregates and synthesizes the literature on cognitive biases in software engineering to generate a comprehensive body of knowledge, understand state of the art research and provide guidelines for future research and practise. Focusing on bias antecedents, effects and mitigation techniques, we identified 65 articles (published between 1990 and 2016), which investigate 37 cognitive biases. Despite strong and increasing interest, the results reveal a scarcity of research on mitigation techniques and poor theoretical foundations in understanding and interpreting cognitive biases. Although bias-related research has generated many new insights in the software engineering community, specific bias mitigation techniques are still needed for software professionals to overcome the deleterious effects of cognitive biases on their work. Index Terms—Antecedents of cognitive bias. cognitive bias. debiasing, effects of cognitive bias. software engineering, systematic mapping. 1 INTRODUCTION OGNITIVE biases are systematic deviations from op- knowledge.

  • Correcting Sampling Bias in Non-Market Valuation with Kernel Mean Matching
    CORRECTING SAMPLING BIAS IN NON-MARKET VALUATION WITH KERNEL MEAN MATCHING Rui Zhang Department of Agricultural and Applied Economics University of Georgia [email protected] Selected Paper prepared for presentation at the 2017 Agricultural & Applied Economics Association Annual Meeting, Chicago, Illinois, July 30 - August 1 Copyright 2017 by Rui Zhang. All rights reserved. Readers may make verbatim copies of this document for non-commercial purposes by any means, provided that this copyright notice appears on all such copies. Abstract Non-response is common in surveys used in non-market valuation studies and can bias the parameter estimates and mean willingness to pay (WTP) estimates. One approach to correct this bias is to reweight the sample so that the distribution of the characteristic variables of the sample can match that of the population. We use a machine learning algorism Kernel Mean Matching (KMM) to produce resampling weights in a non-parametric manner. We test KMM’s performance through Monte Carlo simulations under multiple scenarios and show that KMM can effectively correct mean WTP estimates, especially when the sample size is small and sampling process depends on covariates. We also confirm KMM’s robustness to skewed bid design and model misspecification. Key Words: contingent valuation, Kernel Mean Matching, non-response, bias correction, willingness to pay 2 1. Introduction Nonrandom sampling can bias the contingent valuation estimates in two ways. Firstly, when the sample selection process depends on the covariate, the WTP estimates are biased due to the divergence between the covariate distributions of the sample and the population, even the parameter estimates are consistent; this is usually called non-response bias.

  • New Fossils from Jebel Irhoud, Morocco and the Pan-African Origin of Homo Sapiens Jean-Jacques Hublin1,2, Abdelouahed Ben-Ncer3, Shara E
    LETTER doi:10.1038/nature22336 New fossils from Jebel Irhoud, Morocco and the pan-African origin of Homo sapiens Jean-Jacques Hublin1,2, Abdelouahed Ben-Ncer3, Shara E. Bailey4, Sarah E. Freidline1, Simon Neubauer1, Matthew M. Skinner5, Inga Bergmann1, Adeline Le Cabec1, Stefano Benazzi6, Katerina Harvati7 & Philipp Gunz1 Fossil evidence points to an African origin of Homo sapiens from a group called either H. heidelbergensis or H. rhodesiensis. However, a the exact place and time of emergence of H. sapiens remain obscure because the fossil record is scarce and the chronological age of many key specimens remains uncertain. In particular, it is unclear whether the present day ‘modern’ morphology rapidly emerged approximately 200 thousand years ago (ka) among earlier representatives of H. sapiens1 or evolved gradually over the last 400 thousand years2. Here we report newly discovered human fossils from Jebel Irhoud, Morocco, and interpret the affinities of the hominins from this site with other archaic and recent human groups. We identified a mosaic of features including facial, mandibular and dental morphology that aligns the Jebel Irhoud material with early or recent anatomically modern humans and more primitive neurocranial and endocranial morphology. In combination with an age of 315 ± 34 thousand years (as determined by thermoluminescence dating)3, this evidence makes Jebel Irhoud the oldest and richest African Middle Stone Age hominin site that documents early stages of the H. sapiens clade in which key features of modern morphology were established. Furthermore, it shows that the evolutionary processes behind the emergence of H. sapiens involved the whole African continent. In 1960, mining operations in the Jebel Irhoud massif 55 km south- east of Safi, Morocco exposed a Palaeolithic site in the Pleistocene filling of a karstic network.

  • Quantifying Aristotle's Fallacies
    mathematics Article Quantifying Aristotle’s Fallacies Evangelos Athanassopoulos 1,* and Michael Gr. Voskoglou 2 1 Independent Researcher, Giannakopoulou 39, 27300 Gastouni, Greece 2 Department of Applied Mathematics, Graduate Technological Educational Institute of Western Greece, 22334 Patras, Greece; [email protected] or [email protected] * Correspondence: [email protected] Received: 20 July 2020; Accepted: 18 August 2020; Published: 21 August 2020 Abstract: Fallacies are logically false statements which are often considered to be true. In the “Sophistical Refutations”, the last of his six works on Logic, Aristotle identified the first thirteen of today’s many known fallacies and divided them into linguistic and non-linguistic ones. A serious problem with fallacies is that, due to their bivalent texture, they can under certain conditions disorient the nonexpert. It is, therefore, very useful to quantify each fallacy by determining the “gravity” of its consequences. This is the target of the present work, where for historical and practical reasons—the fallacies are too many to deal with all of them—our attention is restricted to Aristotle’s fallacies only. However, the tools (Probability, Statistics and Fuzzy Logic) and the methods that we use for quantifying Aristotle’s fallacies could be also used for quantifying any other fallacy, which gives the required generality to our study. Keywords: logical fallacies; Aristotle’s fallacies; probability; statistical literacy; critical thinking; fuzzy logic (FL) 1. Introduction Fallacies are logically false statements that are often considered to be true. The first fallacies appeared in the literature simultaneously with the generation of Aristotle’s bivalent Logic. In the “Sophistical Refutations” (Sophistici Elenchi), the last chapter of the collection of his six works on logic—which was named by his followers, the Peripatetics, as “Organon” (Instrument)—the great ancient Greek philosopher identified thirteen fallacies and divided them in two categories, the linguistic and non-linguistic fallacies [1].
