Edward Robinson First page of article [source] The Prevalence of Lying in America: Three Studies of Self-Reported LiesHUMAN COMMUNICATION RESEARCH, Issue 1 2010Kim B. Serota This study addresses the frequency and the distribution of reported lying in the adult population. A national survey asked 1,000 U.S. adults to report the number of lies told in a 24-hour period. Sixty percent of subjects report telling no lies at all, and almost half of all lies are told by only 5% of subjects; thus, prevalence varies widely and most reported lies are told by a few prolific liars. The pattern is replicated in a reanalysis of previously published research and with a student sample. Substantial individual differences in lying behavior have implications for the generality of truth,lie base rates in deception detection experiments. Explanations concerning the nature of lying and methods for detecting lies need to account for this variation. L'importance du mensonge aux États-Unis : trois études de mensonges auto-déclarés Kim B. Serota, Timothy R. Levine, Franklin J. Boster Cette étude aborde la fréquence et la distribution des mensonges déclarés par la population adulte. Un sondage national a demandéŕ 1 000 adultes américains de déclarer le nombre de mensonges racontés dans une période de 24 heures. 60 % des sujets ont rapporté ne pas avoir dit de mensonge du tout et prčs de la moitié de ces mensonges sont racontés par 5 % des sujets. L'importance des mensonges varie donc largement et la plupart des mensonges déclarés sont formulés par un petit nombre de menteurs prolifiques. Cette tendance se retrouve également dans une nouvelle analyse de recherches déjŕ publiées et dans l'échantillon étudiant. Des différences individuelles importantes dans les comportements mensongers ont également des conséquences pour la généralité d'un taux de référence vérité,mensonge dans les expériences de détection de la tromperie. Les explications concernant la nature du mensonge et les méthodes de détection de mensonges doivent prendre en compte cette variation. Mots clés : tromperie, mensonge, différences individuelles The Prevalence of Lying in America: Three Studies of Self-Reported Lies Research Question: This study addresses the frequency and the distribution of reported lying in the adult population. Significance: In the deception literature, consensus is that most people lie on a daily basis. Yet this view is founded on very little empirical evidence. This research tests the question of lying prevalence. Method: Survey research techniques and descriptive analysis are used to establish base rates and frequency distributions for reported lying behavior. Data source: A national survey asked 1,000 U.S. adults to report the number of lies told in a 24 hour period. Cross-validation is provided by re-analysis of previously reported diary and experimental data and by replication using a sample of 225 students. Findings: The oft-repeated average (arithmetic mean) of one to two lies per day is replicated but the study finds the distribution is highly skewed. On a typical day, 60% of subjects report telling no lies at all, and almost half or all lies are told by only 5% of subjects; thus, prevalence varies widely and most reported lies are told by a few prolific liars. The pattern is replicated in the re-analysis of previously published research and with the student sample. Implications: The findings of a highly skewed distribution render the average number of lies per day misleading. Substantial individual differences in lying behavior also have implications for the generality of truth-lie base-rates in deception detection experiments. Explanations concerning the nature of lying and methods for detecting lies need to account for this variation. Keywords: deception, lies, lying, communication, individual differences Die Prävalenz von Lügen in Amerika. Drei Studien zu selbstberichteten Lügen Forschungsfrage: Diese Studie untersucht die Häufigkeit und Verteilung von Lügen in der erwachsenen Bevölkerung. Zentralität: In der Literatur zu Täuschung besteht Konsens darüber, dass Menschen täglich Lügen. Allerdings basiert diese Feststellung auf wenigen empirischen Daten. Diese Untersuchung testet die Frage nach der Prävalenz von Lügen. Methode: Umfrage und beschreibende Analyse wurden angewandt, um eine Basisrate und Häufigkeitsdistribution für selbstberichtetes Lügenverhalten zu gewinnen. Datenquelle: In einer nationalen Umfrage wurden 1.000 US-amerikanische Erwachsene zur Zahl der Lügen befragt, die sie in 24 Stunden erzählten. Validiert wurden diese Aussagen durch eine erneute Analyse von bereits dokumentierten Tagebuchdaten und Experimentaldaten und durch die Replikation mit einer Stichprobe von 225 Studierenden. Ergebnisse: Der oft wiederholte Durchschnitt (arithmetische Mittel) von ein bis zwei Lügen pro Tag wurde in der Studie repliziert, allerdings zeigte sich auch, dass diese Verteilung schief ist. 60% der Befragten gaben an, an einem typischen Tag keine Lügen zu erzählen, fast die Hälfte aller Lügen wird von nur 5% der Befragten erzählt; die Prävalenz variiert stark und die meisten der berichteten Lügen werden durch wenige produktive Lügner erzählt. Dieses Muster wurde bei einer erneuten Analyse von vorher publizierten Daten und in der Studentenstichprobe repliziert. Implikationen: Die Ergebnisse dieser stark schiefen Verteilung zeigen, dass die durchschnittliche Zahl von Lügen pro Tag irreführend ist. Substantielle individuelle Unterschiede im Lügenverhalten haben Implikationen für die Verallgemeinerbarkeit von Wahrheit-Lüge-Basisraten in Täuschungserfassungs-Experimenten. Erklärungen zur Natur von Lügen und Methoden zur Erfassung von Lügen müssen diese Variation bedenken.

Una encuesta nacional preguntó a 1,000 adultos Estadounidenses que reporten el número de mentiras contadas en un período de 24-horas. 60% de los sujetos reportaron que no dicen mentiras para nada, y casi la mitad son contadas por solo un 5% de los sujetos; así, la prevalencia varía enormemente y muchos reportaron que las mentiras son contadas por pocos mentirosos prolíficos. La pauta es replicada en el re-análisis de investigación previamente publicada y con una muestra de estudiantes. Las diferencias individuales sustanciales en el comportamiento mentiroso tienen implicaciones también para la generalidad del índice basado en la verdad-mentira en los experimentos de detección de decepción. Las explicaciones concernientes a la naturaleza de la mentira y los métodos de detección de mentiras necesitan responder a esta variación.

Potchen Abstract. Potchen EJ (Michigan State University, Michigan, USA). Prospects for progress in diagnostic imaging (Internal Medicine in the 21st Century). J Intern Med 2000; 247: 411,424. New fast-imaging MRI systems designed specifically for cardiac magnetic resonance enable new applications of noninvasive vascular imaging. The use of functional MRI and diffusion tensor imaging to map brain function and structure offers a new dimension to an understanding of the human condition. Clinical applications of functional MRI will influence many specialties including surgery, education, and rehabilitation. Functional imaging has the potential to visualize the regional concentration of specific proteins. This imaging at the level of molecules may be possible by use of a contrast material whose signal is changed by local enzymatic activity. The three-dimensional digital data collected in modern imaging techniques allow for virtual endoscopy in the respiratory, alimentary, and cardiovascular systems. Virtual endoscopy may replace many of the more invasive diagnostic methods in the near future. The measurement of clinical decision-making through observer performance studies better informs both the physician and the patient on how to improve upon the quality of clinical practice. These prospects for progress reinforce diagnostic imaging as a cornerstone in medical informatics. The history of creating images used in medicine reveals the invention of diagnostic tools which may provide new information but premature use can result in improper application of a poorly understood technology. Research into the use of new technology may be as important as the technology itself in improving the human condition.

MWF is a known cause of hypersensitivity pneumonitis (HP). Recent reports of outbreaks of hypersensitivity HP secondary to exposure to MWF are reported. Design Cases were identified through the Occupational Disease surveillance system in the State of Michigan and from referrals for evaluation to the Division of Occupational and Environmental Medicine at Michigan State University (MSU). Each patient underwent a clinical examination including an occupational history, lung function studies, radiographic imaging, and in some cases lung biopsies. Following the diagnosis of definite HP, an industrial hygiene investigation was carried out, which included a plant walk-through, and review of the "Injury and Illness" log. Air monitoring and microbial sampling results were reviewed. Results As part of Michigan's mandatory surveillance system for occupational illnesses, seven cases of suspected HP were identified in 2003,2004 from three facilities manufacturing automobile parts in Michigan. Each plant used semi-synthetic MWFs, and conducted a MWF management program including biocide additions. Two facilities had recently changed the MWF before the cases arose. Growth of mycobacteria was found in these two MWFs. Breathing zone samples for particulates of two employees in plant A (two cases) ranged from 0.48 to 0.56 mg/m3. In plant B (four cases), two employees' sampling results ranged from 0.10 to 0.14 mg/m3. No air sampling data were available from plant C. Conclusion Hypersensitivity pneumonitis due to exposure to MWFs is under-recognized by health care providers, and current surveillance systems are inadequate to provide a true estimate of its occurrence. HP arose from environments with exposures well below the Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for MWF, and in one case from exposures well below the National Institute of Occupational Safety and Health (NIOSH) recommended exposure limit (REL). The sporadic nature of reports of HP in relationship to MWF probably represents a combination of workplace changes that cause the disease and inadequate recognition and reporting of the disease when it does occur. Physician awareness of HP secondary to MWF and an effective medical surveillance program are necessary to better understanding the epidemiology and prevention of this disease. Am. J. Ind.

[source] Comparative sugar recovery and fermentation data following pretreatment of poplar wood by leading technologiesBIOTECHNOLOGY PROGRESS, Issue 2 2009Charles E. Wyman Abstract Through a Biomass Refining Consortium for Applied Fundamentals and Innovation among Auburn University, Dartmouth College, Michigan State University, the National Renewable Energy Laboratory, Purdue University, Texas A&M University, the University of British Columbia, and the University of California at Riverside, leading pretreatment technologies based on ammonia fiber expansion, aqueous ammonia recycle, dilute sulfuric acid, lime, neutral pH, and sulfur dioxide were applied to a single source of poplar wood, and the remaining solids from each technology were hydrolyzed to sugars using the same enzymes. Identical analytical methods and a consistent material balance methodology were employed to develop comparative performance data for each combination of pretreatment and enzymes. Overall, compared to data with corn stover employed previously, the results showed that poplar was more recalcitrant to conversion to sugars and that sugar yields from the combined operations of pretreatment and enzymatic hydrolysis varied more among pretreatments. However, application of more severe pretreatment conditions gave good yields from sulfur dioxide and lime, and a recombinant yeast strain fermented the mixed stream of glucose and xylose sugars released by enzymatic hydrolysis of water washed solids from all pretreatments to ethanol with similarly high yields. An Agricultural and Industrial Advisory Board followed progress and helped steer the research to meet scientific and commercial needs. © 2009 American Institute of Chemical Engineers Biotechnol. Prog., 2009 [source] The Problem of Media HabitsCOMMUNICATION THEORY, Issue 2 2010Robert LaRose To what extent is repeated media consumption behavior a matter of habit rather than continuing and active self-instruction? The physiological and cognitive origins of habits are examined in the context of current research in neurology and social psychology. The result is a reconceptualization of media habits along a continuum from consciously enacted behaviors to those that are activated automatically by external stimuli. Communication research perspectives of the role of habits in media consumption are critically reviewed. From this analysis, habits emerge as automatic thought processes that are powerful predictors of media behavior and a model of habitual media consumption is proposed. Le problčme des habitudes médiatiques Robert LaRose Dans quelle mesure la répétition d'un comportement de consommation médiatique est-elle une affaire d'habitude plutôt qu'un choix continu et actif? Les origines physiologiques et cognitives des habitudes sont étudiées dans le contexte de la recherche actuelle en neurologie et en psychologie sociale. Il en résulte une reconceptualisation des habitudes médiatiques selon un continuum allant des comportements conscients ŕ ceux qui sont automatiquement activés par des stimulus extérieurs. Les perspectives de la recherche en communication sur le rôle des habitudes dans la consommation médiatique sont passées en revue d'un ,il critique. De cette analyse, les habitudes émergent comme étant des processus de pensée automatiques qui sont de forts prédicteurs des comportements médiatiques. Un modčle de la consommation médiatique habituelle est proposé. Das Problem von Mediengewohnheiten Robert LaRose Inwiefern ist ein wiederholtes Medienkonsumverhalten eine Frage der Gewohnheit und nicht der ständigen aktiven Selbstkonstruktion? Im Kontext aktueller Forschung in der Neurologie und Sozialpsychologie werden die physiologischen und kognitiven Ursprünge von Gewohnheiten betrachtet. Das Ergebnis ist eine Neukonzeptualisierung von Mediengewohnheiten entlang eines Kontinuums von bewusst ausgeführten Verhaltensweisen hin zu jenen Verhaltensweisen, die automatisch von externalen Stimuli aktiviert werden. Die Perspektive der Kommunikationsforschung zur Rolle von Gewohnheiten bei der Mediennutzung wird kritisch untersucht. Basierend auf dieser Analyse entstehen Gewohnheiten als automatische Gedankenprozesse, die wiederum starke Prädiktoren für Medienverhalten sind. Ein Modell der habitualisierten Mediennutzung wird vorgeschlagen. El Problema de los Hábitos de los Medios Robert LaRose Department of Telecommunication, Information Studies, and Media, Michigan State University, East Lansing, MI 48824, USA Resumen żHasta qué punto el comportamiento repetitivo de consumo de los medios es un asunto de hábito en vez de auto instrucción continúa y activa? Los orígenes psicológicos y cognitivos de los hábitos son examinados en el contexto de la investigación corriente en neurología y psicología social. El resultado es una reconceptualización de los hábitos de los medios a través de un continuo entre los comportamientos conscientemente representados y aquellos que son automáticamente activados por estímulos externos. Las perspectivas de la investigación en comunicación sobre el rol de los hábitos de consumo de los medios son revisados críticamente. De este análisis, los hábitos emergen como procesos de pensamiento automático los cuales son vaticinadores poderosos del comportamiento de los medios y un modelo de consumo habitual de los medios es propuesto.
