The image and advocacy of public health in American caricature and cartoons from 1860 to 1900.

PubMed Central

Hansen, B

1997-01-01

The decades just before and after the founding of the American Public Health Association in 1872 saw an efflorescence of political cartooning and caricature in national-circulation weeklies. Part of the political and social critique that cartoonists and their editors provided the public focused on needs or opportunities for preventing illness and accidents. This paper presents a small selection of editorial cartoons that agitated in support of public health activities over 4 decades. The goals are to illustrate several concerns that rose to national prominence in that era, to examine the kinds of imagery that newspapers and magazine editors offered their readers, and to observe how frequently the public was encouraged to see politicians and commercial interests as responsible for preventable health problems. This discussion focuses exclusively on propagandistic images, leaving aside the reportorial depictions of events in the news and the neutral illustrations of methods and machines in scientific and technical publications.

Moral theories in teaching applied ethics.

PubMed

Lawlor, Rob

2007-06-01

It is argued, in this paper, that moral theories should not be discussed extensively when teaching applied ethics. First, it is argued that, students are either presented with a large amount of information regarding the various subtle distinctions and the nuances of the theory and, as a result, the students simply fail to take it in or, alternatively, the students are presented with a simplified caricature of the theory, in which case the students may understand the information they are given, but what they have understood is of little or no value because it is merely a caricature of a theory. Second, there is a methodological problem with appealing to moral theories to solve particular issues in applied ethics. An analogy with science is appealed to. In physics there is a hope that we could discover a unified theory of everything. But this is, of course, a hugely ambitious project, and much harder than, for example, finding a theory of motion. If the physicist wants to understand motion, he should try to do so directly. We would think he was particularly misguided if he thought that, to answer this question, he first needed to construct a unified theory of everything.

French Crossings: II. Laughing Over Boundaries

PubMed Central

Jones, Colin

2016-01-01

Under the generic title, ‘French Crossings’, this Presidential Address explores the history of laughter in French society, and humour’s potential for trangressing boundaries. It focuses on the irreverent and almost entirely unknown book of comic drawings entitled Livre de caricatures tant Bonnes que mauvaises (Book of Caricatures, both Good and Bad), that was composed between the 1740s and the mid-1770s by the luxury Parisian embroiderer and designer, Charles-Germain de Saint-Aubin, and his friends and family. The bawdy laughter that the book seems intended to provoke gave it its nickname of the Livre de culs (Book of Arses). Yet despite the scatological character of many of the drawings, the humour often conjoined lower body functions with rather cerebral and erudite wit. The laughter provoked unsparingly targeted and exposed to ridicule the social elite, cultural celebrities and political leaders of Ancien Regime France. This made it a dangerous object, which was kept strictly secret. Was this humour somehow pre- or proto-Revolutionary? In fact, the work is so embedded in the culture of the Ancien Regime that 1789 was one boundary that the work signally fails to cross. PMID:27630375

Darwin and Religion: Correcting the Caricatures

NASA Astrophysics Data System (ADS)

Brooke, John Hedley

2010-05-01

Much has been written on the subject of Darwinism and religion, but rather less on the development of Darwin’s own thinking on religious matters and how it changed over time. What were his religious, or anti-religious, beliefs? Did he believe that his theory of evolution by natural selection was incompatible with belief in a Creator? Was it his revolutionary science that turned him into an agnostic? If not, what other considerations affected his judgment? The aim of this paper is to illuminate these questions and, in so doing, to correct some popular caricatures that frequently appear when the two words ‘science’ and ‘religion’ are juxtaposed. Darwin himself reflected deeply on the theological problem of suffering and justified his naturalism on the ground that it made the deity less directly responsible for the more repulsive features of creation. The deism that he espoused at the time of writing his Origin of Species also left its mark in his conviction that it would be demeaning to the deity to suggest that its purposes could not be achieved through natural causes. The diversity of the religious responses also corrects a common misperception that there was almost unanimous hostility from religious interests.

Producing Parsons' reputation: early critiques of Talcott Parsons' social theory and the making of a caricature.

PubMed

Owens, B Robert

2010-01-01

This article examines the critical responses to Talcott Parsons' first major work, The Structure of Social Action (1937), and his two subsequent books, Toward a General Theory of Action and The Social System (both 1951). Because Parsons' work was the subject of such virulent debate, we cannot fully understand Parsons' impact on the discipline of sociology without understanding the source and nature of those early criticisms. I trace the responses to Parsons, first through book reviews and private letters and then in the more substantial statements of C. Wright Mills, George Homans, and Alvin Gouldner, from the largely positive but superficial reception of Structure to the polemics that followed Parsons' 1951 works. In the late 1930s and 1940s, Parsons' reputation grew steadily but there remained no careful reception of Structure, fostering resentment toward Parsons in some quarters while precluding a sophisticated understanding of his work. After 1951, a few critics capitalized on that tension, writing sweeping rejections of Parsons' work that spoke to a much broader audience of sociologists. That dynamic, coupled with Parsons' own indifference toward his harshest critics, produced a situation in which many sociologists simply chose not to read Parsons in the 1950s and 1960s, reinforcing a caricature and distorting perceptions of Parsons' place in mid-twentieth-century American sociology.

As a keynote to a conference bringing together psychoanalysts and analytical psychologists, this paper addresses different mythic attitudes toward the unconscious, starting with the caricatures of Oedipus and Narcissus that the author feels Jung and Freud originally projected onto each other in the course of their quarrel. He moves on to the fairytale-like stories of Perseus and Beauty and the Beast to discover more complex images of the stance taken in relation to the unconscious by present-day analysts working within both the Jungian and the Freudian traditions.

The recent banking crises have made it clear that increasingly complex strategies for managing risk in individual banks have not been matched by corresponding attention to overall systemic risks. We explore some simple mathematical caricatures for ‘banking ecosystems’, with emphasis on the interplay between the characteristics of individual banks (capital reserves in relation to total assets, etc.) and the overall dynamical behaviour of the system. The results are discussed in relation to potential regulations aimed at reducing systemic risk. PMID:19864264

Neuron Bifurcations in an Analog Electronic Burster

NASA Astrophysics Data System (ADS)

Savino, Guillermo V.; Formigli, Carlos M.

2007-05-01

Although bursting electrical activity is typical in some brain neurons and biological excitable systems, its functions and mechanisms of generation are yet unknown. In modeling such complex oscillations, analog electronic models are faster than mathematical ones, whether phenomenologically or theoretically based. We show experimentally that bursting oscillator circuits can be greatly simplified by using the nonlinear characteristics of two bipolar transistors. Since our circuit qualitatively mimics Hodgkin and Huxley model neurons bursting activity, and bifurcations originating neuro-computational properties, it is not only a caricature but a realistic model.

Unpopular, overweight, and socially inept: reconsidering the stereotype of online gamers.

PubMed

Kowert, Rachel; Festl, Ruth; Quandt, Thorsten

2014-03-01

Online gaming has become an activity associated with a highly specific, caricatured, and often negative image. This "stereotype" has permeated the collective consciousness, as online gamers have become common caricatures in popular media. A lack of comprehensive demographic inquiries into the online gaming population has made it difficult to dispute these stereotypical characteristics and led to rising concerns about the validity of these stereotypes. The current study aims to clarify the basis of these negative characterizations, and determine whether online video game players display the social, physical, and psychological shortcomings stereotypically attributed them. Sampling and recruiting was conducted using a two-stage approach. First, a representative sample of 50,000 individuals aged 14 and older who were asked about their gaming behavior in an omnibus telephone survey. From this sample, 4,500 video game players were called for a second telephone interview, from which the current data were collected. Only those participants who completed all of the questions relating to video game play were retained for the current analysis (n=2,550). Between- and within-group analyses were enlisted to uncover differences between online, offline, and nongame playing communities across varying degrees of involvement. The results indicate that the stereotype of online gamers is not fully supported empirically. However, a majority of the stereotypical attributes was found to hold a stronger relationship with more involved online players than video game players as a whole, indicating an empirical foundation for the unique stereotypes that have emerged for this particular subgroup of video game players.

Enhancement of face recognition learning in patients with brain injury using three cognitive training procedures.

PubMed

Powell, Jane; Letson, Susan; Davidoff, Jules; Valentine, Tim; Greenwood, Richard

2008-04-01

Twenty patients with impairments of face recognition, in the context of a broader pattern of cognitive deficits, were administered three new training procedures derived from contemporary theories of face processing to enhance their learning of new faces: semantic association (being given additional verbal information about the to-be-learned faces); caricaturing (presentation of caricatured versions of the faces during training and veridical versions at recognition testing); and part recognition (focusing patients on distinctive features during the training phase). Using a within-subjects design, each training procedure was applied to a different set of 10 previously unfamiliar faces and entailed six presentations of each face. In a "simple exposure" control procedure (SE), participants were given six presentations of another set of faces using the same basic protocol but with no further elaboration. Order of the four procedures was counterbalanced, and each condition was administered on a different day. A control group of 12 patients with similar levels of face recognition impairment were trained on all four sets of faces under SE conditions. Compared to the SE condition, all three training procedures resulted in more accurate discrimination between the 10 studied faces and 10 distractor faces in a post-training recognition test. This did not reflect any intrinsic lesser memorability of the faces used in the SE condition, as evidenced by the comparable performance across face sets by the control group. At the group level, the three experimental procedures were of similar efficacy, and associated cognitive deficits did not predict which technique would be most beneficial to individual patients; however, there was limited power to detect such associations. Interestingly, a pure prosopagnosic patient who was tested separately showed benefit only from the part recognition technique. Possible mechanisms for the observed effects, and implications for rehabilitation, are discussed.

Caveat actor, Caveat emptor: some notes on some hazards of Tinseltown teaching.

PubMed

Greenberg, Harvey Roy

2009-06-01

The use of films in teaching psychiatry and psychotherapy remains problematic for a number of reasons. The bulk of films are made for commercial reasons, not for educational purposes. Scientific truth is often overshadowed by narrative requirement in films. In most 'mainstream' cinema and 'indie' productions, diagnostic accuracy is still seriously compromised by narrative considerations. Clinical reality continues to be undermined and overridden by the need--as makers see it--to tell a powerful story in aid of huge box office receipts. Therapists in films are also often caricatures and caution must be employed in using cinema in real-time individual therapy.

As they became more widely adopted in eighteenth- and nineteenth-century France, wet-nursing and wet-nurses appeared prominently in the iconography of the time. Such images turned negative as criticism against “mercenary breast-feeding” mounted. Over the nineteenth century in particular, wet-nurses were heavily featured in press caricatures: they were being mocked while described as simple-minded, dumb, greedy creatures, with proclivities ranging from a taste for garish attire, to sexual appetites fuelling trysts in public gardens with soldiers on leave. A representative sample of such images will be selected to highlight the codes and values underpinning this mockery.

Eugene Bleuler's four As.

PubMed

McNally, Kieran

2009-05-01

One hundred years have passed since Eugene Bleuler first coined the term schizophrenia. In that time, a simple mnemonic, the Four As, has come to distort his complex descriptive pathology. However, at no stage did Bleuler give precedence to the Four As or describe them in such a fashion. The Four As are a caricatured representation of Bleuler's schizophrenia that distorts the later conceptualization of schizophrenia. Despite historical attempts to signal this error, it remains virulent in the schizophrenia literature, masquerading as historical fact. This article corrects this distortion and clarifies the precise relationship of the Four As to Bleuler's thinking. It discusses their emergence and persistence, and draws attention to Bleuler's emphasis of other important symptoms--most notably splitting.

Mesoscopic description of random walks on combs

Méndez, Vicenç; Iomin, Alexander; Campos, Daniel; Horsthemke, Werner

2015-12-01

Combs are a simple caricature of various types of natural branched structures, which belong to the category of loopless graphs and consist of a backbone and branches. We study continuous time random walks on combs and present a generic method to obtain their transport properties. The random walk along the branches may be biased, and we account for the effect of the branches by renormalizing the waiting time probability distribution function for the motion along the backbone. We analyze the overall diffusion properties along the backbone and find normal diffusion, anomalous diffusion, and stochastic localization (diffusion failure), respectively, depending on the characteristics of the continuous time random walk along the branches, and compare our analytical results with stochastic simulations.

From Brain-Environment Connections to Temporal Dynamics and Social Interaction: Principles of Human Brain Function.

PubMed

Hari, Riitta

2017-06-07

Experimental data about brain function accumulate faster than does our understanding of how the brain works. To tackle some general principles at the grain level of behavior, I start from the omnipresent brain-environment connection that forces regularities of the physical world to shape the brain. Based on top-down processing, added by sparse sensory information, people are able to form individual "caricature worlds," which are similar enough to be shared among other people and which allow quick and purposeful reactions to abrupt changes. Temporal dynamics and social interaction in natural environments serve as further essential organizing principles of human brain function. Copyright © 2017 Elsevier Inc. All rights reserved.

Sophistry, the Sophists and modern medical education.

PubMed

Macsuibhne, S P

2010-01-01

The term 'sophist' has become a term of intellectual abuse in both general discourse and that of educational theory. However the actual thought of the fifth century BC Athenian-based philosophers who were the original Sophists was very different from the caricature. In this essay, I draw parallels between trends in modern medical educational practice and the thought of the Sophists. Specific areas discussed are the professionalisation of medical education, the teaching of higher-order characterological attributes such as personal development skills, and evidence-based medical education. Using the specific example of the Sophist Protagoras, it is argued that the Sophists were precursors of philosophical approaches and practices of enquiry underlying modern medical education.

A self-caricature of michelangelo buonarroti hidden in the portrait of vittoria colonna.

PubMed

de Campos, Deivis

2018-04-01

The specialized literature has described how the great anatomist par excellence, Michelangelo Buonarroti (1475-1564), like many other renowned artists of his time, included a self-portrait in many of his works. This article presents novel evidence that Michelangelo inserted his self-portrait into a sketch of his close friend, Vittoria Colonna (1490-1547). This work, made by Michelangelo in 1525, is currently in the collection of the British Museum in London, England. This self-portrait of Michelangelo can serve as a tool for analyzing the artist's probable bodily dimensions and even his state of health during this period of his life. Clin.

Commentary: surviving terrorist cells.

PubMed

Herzig, Rebecca M; Jain, Sarah Lochlann

2009-01-01

The use of violent imagery, war metaphors, and the "survivor" persona in relation to cancer research and treatment are examined, as are consumer-driven approaches to "working toward a cure." The authors ask, what are the cultural and environmental trade-offs of these types of rhetoric? The positions of good guys (survivors, researchers, consumers) versus the enemy (cancer) are critically evaluated. Of especial note is a recent print advertisement that, despite its arresting visual presence, delivers an exceedingly vague message. The authors conclude that the practice of medicine plays a pivotal role in these cultural determinations and that caricatured attributions of cellular violence ultimately divert critical attention from sustained scrutiny of the institutional, social, economic, and political processes that in fact may contribute to the forces that bear on causing cancer.

Post Civil War African American History: Brief Periods of Triumph, and Then Despair.

PubMed

Graff, Gilda

2016-01-01

During Reconstruction, which is often called the most progressive period in American history, African Americans made great strides. By 1868 African American men constituted a majority of registered voters in South Carolina and Mississippi, and by 1870 eighty-five percent of Mississippi's black jurors could read and write. However, Reconstruction was followed by approximately one hundred years of Jim Crow laws, lynching, disenfranchisement, sharecropping, unequal educational resources, terrorism, racial caricatures, and convict leasing. The Civil Rights Revolution finally ended that period of despair, but the era of mass incarceration can be understood as a reaction to the Civil Rights Movement. This article attempts to understand the persistence of racism in the United States from slavery's end until the present.

Lie integrable cases of the simplified multistrain/two-stream model for tuberculosis and dengue fever

Nucci, M. C.; Leach, P. G. L.

2007-09-01

We apply the techniques of Lie's symmetry analysis to a caricature of the simplified multistrain model of Castillo-Chavez and Feng [C. Castillo-Chavez, Z. Feng, To treat or not to treat: The case of tuberculosis, J. Math. Biol. 35 (1997) 629-656] for the transmission of tuberculosis and the coupled two-stream vector-based model of Feng and Velasco-Hernandez [Z. Feng, J.X. Velasco-Hernandez, Competitive exclusion in a vector-host model for the dengue fever, J. Math. Biol. 35 (1997) 523-544] to identify the combinations of parameters which lead to the existence of nontrivial symmetries. In particular we identify those combinations which lead to the possibility of the linearization of the system and provide the corresponding solutions. Many instances of additional symmetry are analyzed.

Focus: Darwin as a cultural icon.

PubMed

Secord, James A

2009-09-01

Since his death in 1882, if not before, Charles Darwin has been a key icon of the modern era. The bearded sage of Down House has been invoked in a wide range of contexts in the English-speaking world, from eugenics and social policy to debates about the implications of science for religious belief. The essays in this Focus section explore the Darwinian image in an unusual diversity of media, examining portrait photographs, portable sculptures,newspaper caricatures, cartoons, after-dinner drinking songs, and long-playing records. They suggest that Darwin's celebrity needs to be understood not as the outcome of the unique qualities of his life and work, but as an aspect of the emergence of the idea of the scientist, a process closely tied to the developing communication and entertainment industries of the late nineteenth and early twentieth centuries.

Nothing in the History of Spanish Anís Makes Sense, Except in the Light of Evolution

Delgado, Juan Antonio; Palma, Ricardo Luis

2011-02-01

We describe, discuss and illustrate a metaphoric parallel between the history of the most famous Spanish liqueur, " Anís del Mono" ( Anís of the Monkey), and the evolution of living organisms in the light of Darwinian theory and other biological hypotheses published subsequent to Charles Darwin's Origin of Species. Also, we report the use of a caricature of a simian Darwin with a positive connotation, perhaps the only one ever produced. We conclude that, like some species in the natural world, Anís of the Monkey has evolved, adapted, survived and become the fittest and most successful anís in the Spanish market and possibly the world. We hope this paper will contribute a new useful metaphor for the teaching of biological evolution.

British anti-vaccination propaganda.

Vandervelde, V D

1974-10-01

In April 1972, "Postal History International" published an article of mine concerning anti-vaccination caricature envelopes, which has led to some correspondence with readers and the discovery of several related items. It seems appropriate, therefore, to summarise the information in these pages, in the hope that this may bring forth knowledgeable comment from others. Details of any foreign propaganda of this sort would be particularly welcome. Meanwhile, this articles summarises what is known of the Society responsible for at least some of the British envelopes, and fills in a little of the historical background. The assistance of Mr. Ritchie Bodily is gratefully acknowledged, while the historical information was culled from the Newspaper Library of the British Museum at Colindale. Certain errors in the initial article can now be corrected, notably as to the name and location of the "persecuted man of Truth".

Some Preliminary Notes on an Empirical Test of Freud's Theory on Depression.

PubMed

Desmet, Mattias

2013-01-01

A review of the literature indicates that empirical researchers have difficulty translating Freud's theory on depression into appropriate research questions and hypotheses. In their attempt to do so, the level of complexity in Freud's work is often lost. As a result, what is empirically tested is no more than a caricature of the original theory. To help researchers avoid such problems, this study presents a conceptual analysis of Freud's theory of depression as it is presented in Mourning and Melancholia (Freud, 1917). In analyzing Freud's theory on the etiology of depression, it is essential to differentiate between (1) an identification with the satisfying and frustrating aspects of the love object, (2) the inter- and an intrapersonal loss of the love object, and (3) conscious and unconscious dynamics. A schematic representation of the mechanism of depression is put forward and a research design by which this schema can be empirically investigated is outlined.

Extraneous factors in judicial decisions

Danziger, Shai; Levav, Jonathan; Avnaim-Pesso, Liora

2011-01-01

Are judicial rulings based solely on laws and facts? Legal formalism holds that judges apply legal reasons to the facts of a case in a rational, mechanical, and deliberative manner. In contrast, legal realists argue that the rational application of legal reasons does not sufficiently explain the decisions of judges and that psychological, political, and social factors influence judicial rulings. We test the common caricature of realism that justice is “what the judge ate for breakfast” in sequential parole decisions made by experienced judges. We record the judges’ two daily food breaks, which result in segmenting the deliberations of the day into three distinct “decision sessions.” We find that the percentage of favorable rulings drops gradually from ≈65% to nearly zero within each decision session and returns abruptly to ≈65% after a break. Our findings suggest that judicial rulings can be swayed by extraneous variables that should have no bearing on legal decisions. PMID:21482790

Situating cognitive/socio-cognitive approaches to student learning in genetics

Kindfield, Ann C. H.

2009-03-01

In this volume, Furberg and Arnseth report on a study of genetics learning from a socio-cultural perspective, focusing on students' meaning making as they engage in collaborative problem solving. Throughout the paper, they criticize research on student understanding and conceptual change conducted from a cognitive/socio-cognitive perspective on several reasonable grounds. However, their characterization of work undertaken from this perspective sometimes borders on caricature, failing to acknowledge the complexities of the research and the contexts within which it has been carried out. In this commentary, I expand their characterization of the cognitive/socio-cognitive perspective in general and situate my own work on genetics learning so as to provide a richer view of the enterprise. From this richer, more situated view, I conclude that research from both perspectives and collaboration between those looking at learning from different perspectives will ultimately provide a more complete picture of science learning.

Message to complementary and alternative medicine: evidence is a better friend than power

PubMed Central

Vickers, Andrew J

2001-01-01

Background Evidence-based medicine (EBM) is being embraced by an increasing number of practitioners and advocates of complementary and alternative medicine (CAM). A significant constituency within CAM, however, appears to have substantive doubts about EBM and some are expressly hostile. Discussion Many of the arguments raised against EBM within the CAM community are based on a caricature radically at odds with established, accepted and published principles of EBM practice. Contrary to what has sometimes been argued, EBM is not cookbook medicine that ignores individual needs. Neither does EBM mandate that only proven therapies should be used. Before EBM, decisions on health care tended to be based on tradition, power and influence. Such modes usually act to the disadvantage of marginal groups. Conclusion By placing CAM on an equal footing with conventional medicine - what matters for both is evidence of effectiveness - EBM provides an opportunity for CAM to find an appropriate and just place in health care.

Modeling source-filter interaction in belting and high-pitched operatic male singing

PubMed Central

Titze, Ingo R.; Worley, Albert S.

2009-01-01

Nonlinear source-filter theory is applied to explain some acoustic differences between two contrasting male singing productions at high pitches: operatic style versus jazz belt or theater belt. Several stylized vocal tract shapes (caricatures) are discussed that form the bases of these styles. It is hypothesized that operatic singing uses vowels that are modified toward an inverted megaphone mouth shape for transitioning into the high-pitch range. This allows all the harmonics except the fundamental to be “lifted” over the first formant. Belting, on the other hand, uses vowels that are consistently modified toward the megaphone (trumpet-like) mouth shape. Both the fundamental and the second harmonic are then kept below the first formant. The vocal tract shapes provide collective reinforcement to multiple harmonics in the form of inertive supraglottal reactance and compliant subglottal reactance. Examples of lip openings from four well-known artists are used to infer vocal tract area functions and the corresponding reactances. PMID:19739766

An Unholy Mess: Why 'The Sanctity of Life Principle' Should Be Jettisoned.

PubMed

Jones, David Albert

2016-11-01

The aim of this article is to present an account of an important element of medical ethics and law which is widely cited but is often confused. This element is most frequently referred to as 'the principle of the sanctity of life', and it is often assumed that this language has a religious provenance. However, the phrase is neither rooted in the traditions it purports to represent nor is it used consistently in contemporary discourse. Understood as the name of an established 'principle' the 'sanctity of life' is virtually an invention of the late twentieth century. The language came to prominence as the label of a position that was being rejected: it is the name of a caricature. Hence there is no locus classicus for a definition of the terms and different authors freely apply the phrase to divergent and contradictory positions. Appeal to this 'principle' thus serves only to perpetuate confusion. This language is best jettisoned in favour of clearer and more traditional ethical concepts.

Chitrachanchala (pictures of unstable mind): mental health themes in Kannada cinema.

Regional movies in India play an important role in portraying mental illness and also depict awareness and attitudes of society towards people with mental health problems. Kannada (the language spoken by 50 million people from the state of Karnataka in South India) cinema has produced a range of movies depicting conditions ranging from psychosis to personality disorders. However, the descriptions of mental illness in several of these movies is vague and often stigmatizing. Some landmark films have involved psychiatrists in producing and directing the movies, including helping with the story line, which have added value to these films. Despite Karnataka being home to some of the important psychiatrists in the country and to some of the most famous and advanced mental health training and treatment centres, depictions of treatment and the portrayal of psychiatrists continues to be caricatured. As is true of many parts of India, treatment methods are often magico-religious, which is what Kannada cinema also reflects.

Who's Missing the Point? A Commentary on Claims that Autistic Persons Have a Specific Deficit in Figurative Language Comprehension.

2012-01-01

It's become a caricature of autistic persons that they don't understand figurative language. Despite empirical evidence to the contrary, three of the four contributions to this special issue endorse this stereotype without question. And all four contributions attribute this supposed deficit to even shakier fallacies, such as the controversial claim that autistic people lack empathy or a 'theory of mind.' In this commentary, we begin by reviewing the literature more exhaustively than the other contributions, and we highlight a point that they missed: Autistic persons are likely to have difficulty comprehending figurative language if they also have difficulty comprehending language in general. There doesn't seem to be a specific deficit in figurative language unique to autism. We also tackle the claim that autistic people lack empathy. And we question the existence of a 'theory of mind area,' while demonstrating the pitfalls that ensnarl researchers when they strain to interpret differences between autistic and non-autistic brain activity as solely autistic deficits.

Face-space: A unifying concept in face recognition research.

2016-10-01

The concept of a multidimensional psychological space, in which faces can be represented according to their perceived properties, is fundamental to the modern theorist in face processing. Yet the idea was not clearly expressed until 1991. The background that led to the development of face-space is explained, and its continuing influence on theories of face processing is discussed. Research that has explored the properties of the face-space and sought to understand caricature, including facial adaptation paradigms, is reviewed. Face-space as a theoretical framework for understanding the effect of ethnicity and the development of face recognition is evaluated. Finally, two applications of face-space in the forensic setting are discussed. From initially being presented as a model to explain distinctiveness, inversion, and the effect of ethnicity, face-space has become a central pillar in many aspects of face processing. It is currently being developed to help us understand adaptation effects with faces. While being in principle a simple concept, face-space has shaped, and continues to shape, our understanding of face perception.

Human heart by art.

Tamir, Abraham

2012-11-01

Heart is of great importance in maintaining the life of the body. Enough to stop working for a few minutes to cause death, and hence the great importance in physiology, medicine, and research. This fact was already emphasized in the Bible in the Book of Proverbs, chapter 4 verse 23: "Keep your heart with all diligence, for out of it is the wellspring of life." Art was able to demonstrate the heart from various aspects; realistically, as done by Leonardo de Vinci who demonstrated the halves of the heart and its blood vessels. Symbolically, as a source of life, the heart was demonstrated by the artist Mrs. Erlondeiel, as a caricature by Salvador Dali, as an open heart by Sawaya, etc. Finally, it should be emphasized that different demonstrations of the human heart by many artworks make this most important organ of our body (that cannot be seen from outside) more familiar and clearer to us. And this is the purpose of this article-to demonstrate the heart through a large number of artworks of different kinds.

Education, Enlightenment and Positivism: The Vienna Circle's Scientific World-Conception Revisited

NASA Astrophysics Data System (ADS)

Uebel, Thomase.

The scientific world-conception is properly understood as an enlightenment philosophy only if the current reassessment of the historical Vienna Circle(as opposed to the caricature still prevalent in the popular philosophical imagination) is once more extended to comprehend not only its thorough-going epistemological anti-foundationalism, but also the voluntarist point of its ethical`non-cognitivism'. That is to say, the scientific world-conception is properly understood as the opposite of village positivism only if it is recognized that it has an `other' and that the scientific world-conception was meant by its proponents to perform its enlightenment work only in conjunction with that other of scientific reason - ethical will and willing. Scientific reason cannot determine all there is to determine, it cannot determine the will. In this sense, there was, pace village positivism, more than scientific reason dreamt of. Scientific reason was not made absolute: rather, its (self-) clarification was required if a satisfactory view of its place in `life' was to be attained.

Chinese men and women in the United States and Hong Kong: body and self-esteem ratings as a prelude to dieting and exercise.

Davis, C; Katzman, M A

1998-01-01

The present study compared the body and weight satisfaction, self-esteem, and depression of Chinese male and female university students in Hong Kong and the United States and assessed the impact of these ratings on compensatory behavior such as dieting and exercise. Self-report measures were administered to 501 Chinese participants in the language of their university's locale. Females reported significantly more body dissatisfaction and depression, and males reported greater weight dissatisfaction (the majority of men wishing to be larger). Overall, Chinese subjects in Hong Kong reported significantly more body and weight dissatisfaction, lower self-esteem, higher depression, more dieting, and less exercise as compared to their counterparts in the United States. Asian students in this study mirrored gendered patterns previously reported in Caucasian samples with respect to the relation of body image, self-esteem, and mood. For both sexes, there appeared to be a caricatured mimicking of the bodies perceived to be associated with the dominant culture--men wanted to be larger while the women wanted to be even more petite.

Teaching intelligent design or sparking interest in science? What players do with Will Wright's Spore

Owens, Trevor

2012-12-01

The 2008 commercial video game Spore allowed more than a million players to design their own life forms. Starting from single-celled organisms players played through a caricature of natural history. Press coverage of the game's release offer two frames for thinking about the implications of the game. Some scientists and educators saw the game as a troubling teacher of intelligent design, while others suggested it might excite public interest in science. This paper explores the extent to which these two ways of thinking about the game are consistent with what players have done with the game in its online community. This analysis suggests that, at least for the players participating in this community, the game has not seduced them into believing in intelligent design. Instead the activities of these players suggest that the game has played a catalytic role in engaging the public with science. These findings indicate that designers of educational games may wish to consider more deeply tensions between prioritizing accuracy of content in educational games over player engagement.

Towards a strategy for older people in Ireland.

PubMed

O'Shea, E

2007-09-01

This paper makes the case for the development of a new National Strategy for Older People in Ireland. The new Strategy should be holistic and focus on all aspects of older people's lives. New opportunities for older people to maximize their capabilities in economic, social and civic life should be created and supported. If these opportunities are to arise, ageist attitudes need to be confronted and defeated. Older people should be treated as individuals, their preferences respected and their autonomy guaranteed. The vulnerability of older people should be protected where warranted, particularly in respect to the regulation of long-stay care. But it is equally important not to stereotype all older people as vulnerable and constantly in need of intervention and support. That is not the reality and repeatedly caricaturing older people as dependent is ageist in itself. Older people have to capacity to contribute much more to society than we currently allow them, in relation to work, volunteering, wisdom and culture. This paper provides the framework for the emergence of a new Strategy which will facilitate a much more significant role for older people in Irish society.

The lung sound auscultation is a part of everyday practice of most physicians. This skill used to be in practice in antique times, but it did not gain any particular attention until the beginning of the 19th century when Laennec systematized his observations, so that the method became generally accepted as the means of examining the patient. Today the stethoscope has almost become the symbol of medical profession, and without it no worthy caricature on behalf of a physician is possible. In this article except short historical review of the lung auscultation, the new technical innovations, including the use of computers which have led to new insights into the characteristics of the lung sounds in health and disease have been shown. Indeed, the technical innovations have insured more accurate measurement of all characteristics of lung sounds, and in connection with this enabled the coining of new terms, especially for adventitious lung sounds. As the whole civilized world has agreed upon the terminology, in the radiance of the above mentioned we are also proposing new terminology for adventitious lung sounds.

Polanski, F

2014-06-01

The focus of this study was the collective images of aging that were unconsciously used despite rationally led social discourse on aging. Hypothesized was that despite changes in aging over the last 50 years these images went unaltered and thereby negative stereotypes of previous generations were maintained. In an effort to verify this hypothesis images of aging in cartoons were empirically examined, a first in the field of German language. Using a social scientific operationalization of age stereotypes and culturally historical topoi as a basis, a content analysis was conducted on 2,546 cartoons (with 8,882 characters) from the years 1960-1964 and 2007. In general both young and old age are equally encoded with negative connotations by deficient characteristics and acknowledged stereotypes partially significantly more often in the cartoons from 2007 than from 1960-1964. The last 50 years have seen no substantial changes in the images of aging as depicted by magazine and newspaper cartoons. Humor requires more frequent analysis as it often unconsciously reveals socially unacceptable images of aging, even those embedded in science.

What Mary Toft Felt: Women’s Voices, Pain, Power and the Body

PubMed Central

2015-01-01

In autumn 1726, Mary Toft began to deliver rabbits in Godalming, Surrey. The case became a sensation and was reported widely in newspapers, popular pamphlets, poems and caricatures. Toft was attended by at least six different doctors, some members of the Royal College of Physicians or attached to the Royal Court, but no doctor declared the affair a hoax until Toft herself confessed on 7 December 1726. This article focuses on Toft’s three surviving confessions in order to explore not the doctors or even wider representations of the affair but instead the person of Mary Toft herself. These rare sources give rare insight into one woman’s experiences of reproduction in the early eighteenth century. The essay engages with recent work on recovering women’s voices in the past, reconstructing Mary Toft’s words and her embodied and affective experience of the affair. These documents suggest a revision to our understanding of the hoax of 1726, one that situates the affair not in the context of the scientific revolution and Enlightenment or the assumption of men’s control over midwifery, but instead in the context of power dynamics amongst women in the practices of early-modern reproduction and birth.

Vindicating virtue: a critical analysis of the situationist challenge against Aristotelian moral psychology.

PubMed

Croom, Adam M

2014-03-01

This article provides a critical analysis of the situationist challenge against Aristotelian moral psychology. It first outlines the details and results from four paradigmatic studies in psychology that situationists have heavily drawn upon in their critique of the Aristotelian conception of virtuous characteristics, including studies conducted by Hartshorne and May (1928), Darley and Batson (Journal of Personality and Social Psychology 27:100-108, 1973), Isen and Levin (Journal of Personality and Social Psychology 21:384-388, 1972), and Milgram (Journal of Abnormal and Social Psychology 67:371-378, 1963). It then presents ten problems with the way situationists have used these studies to challenge Aristotelian moral psychology. After challenging the situationists on these grounds, the article then proceeds to challenge the situationist presentation of the Aristotelian conception, showing that situationists have provided an oversimplified caricature of it that goes against the grain of much Aristotelian text. In evaluating the situationist challenge against the actual results from empirical research as well as primary Aristotelian text, it will be shown that the situationist debate has advanced both an extreme, untenable view about the nature of characteristics and situations, as well as an inaccurate presentation of the Aristotelian view.

From the doctor's workshop to the iron cage? Evolving modes of physician control in US health systems.

PubMed

Kitchener, Martin; Caronna, Carol A; Shortell, Stephen M

2005-03-01

As national health systems pursue the common goals of containing expenditure growth and improving quality, many have sought to replace autonomous modes (systems) of physician control that rely on initial professional training and subsequent peer review. A common approach has involved extending bureaucratic modes of physician control that employ techniques such as hierarchical coordination and salaried positions. This paper applies concepts from studies of professional work to frame an empirical analysis of emergent bureaucratic modes of physician control in US hospital-based systems. Conceptually, we draw from recent studies to update Scott's (Health Services Res. 17(3) (1982) 213) typology to specify three bureaucratic modes of physician control: heteronomous, conjoint, and custodial. Empirically, we use case study evidence from eight US hospital-based systems to illustrate the heterogeneity of bureaucratic modes of physician control that span each of the ideal types. The findings indicate that some influential analysts perpetuate a caricature of bureaucratic organization which underplays its capacity to provide multiple modes of physician control that maintain professional autonomy over the content of work, and present opportunities for aligning practice with social goals.

Somatotyping using 3D anthropometry: a cluster analysis.

Olds, Tim; Daniell, Nathan; Petkov, John; David Stewart, Arthur

2013-01-01

Somatotyping is the quantification of human body shape, independent of body size. Hitherto, somatotyping (including the most popular method, the Heath-Carter system) has been based on subjective visual ratings, sometimes supported by surface anthropometry. This study used data derived from three-dimensional (3D) whole-body scans as inputs for cluster analysis to objectively derive clusters of similar body shapes. Twenty-nine dimensions normalised for body size were measured on a purposive sample of 301 adults aged 17-56 years who had been scanned using a Vitus Smart laser scanner. K-means Cluster Analysis with v-fold cross-validation was used to determine shape clusters. Three male and three female clusters emerged, and were visualised using those scans closest to the cluster centroid and a caricature defined by doubling the difference between the average scan and the cluster centroid. The male clusters were decidedly endomorphic (high fatness), ectomorphic (high linearity), and endo-mesomorphic (a mixture of fatness and muscularity). The female clusters were clearly endomorphic, ectomorphic, and the ecto-mesomorphic (a mixture of linearity and muscularity). An objective shape quantification procedure combining 3D scanning and cluster analysis yielded shape clusters strikingly similar to traditional somatotyping.

A plea for virtue in ethics.

2012-01-01

Comments on the original article, "Nonrational processes in ethical decision making" by M. D. Rogerson et al (see record 2011-19198-001). The current authors suggest that Rogerson, Gottlieb, Handelsman, Knapp, and Younggren (October 2011) presumed that the only ethical theories available for grounding decision-making models are of the rational, neoliberal variety. Rogerson et al stated, "Contextual, interpersonal, and intuitive factors are inextricably linked and inexorably influential in the process of ethical decision making. Ethical theory would benefit from encompassing these subtle yet powerful forces" (Rogerson et al., 2011, p. 616). They sought to augment these models with a cluster of contextual considerations, appending to them accounts of emotion, context, and intuition. First, notwithstanding the theories attributed to (the caricature of) Kant and his ilk, there are several ethical theories that include an account of what Rogerson et al. (2011) consider to be "nonrational" processes. From feminist theories to narrative ethics, sophisticated contextual theories have been developed and are readily available. Second, we question whether thick contextual considerations can simply be tacked on to extant models of decision making originally built upon a philosophical foundation that assumes a rational, autonomous agent who deliberates independently and logically.

Costentin, J

2008-08-01

Today, the main route of introduction of tetrahydrocannabinol (THC), the main active substance of cannabis, into the human body is via the lungs, from smokes produced by combustion of a haschich-tobacco mixture. The use of a water pipe (nargileh-like) intensifies its fast supply to the body. THC reaches the brain easily where it stimulates CB1 receptors; their ubiquity underlies a wide variety of effects. THC disappears from extracellular spaces by dissolving in lipid rich membranes, and not by excretion from the body. This is followed by a slow release, leading to long lasting effects originating from brain areas containing a large proportion of spare receptors ("reserve receptors"). Far from mimicking the effects of endocannabinoids, THC caricatures and disturbs them. It induces both psychical and physical dependencies, but the perception of withdrawal is weak on account of its very slow elimination. THC disturbs cognition. Acutely, it develops anxiolytic- and antidepressant-like effects, which causes a lot of users to abuse THC, thus leading to a tolerance (desensitization of CB1 receptors) making anxiety and depression to reappear more intensely than originally. THC has close relationships with schizophrenia. It incites to tobacco, alcohol and heroine abuses.

Obesity and nutritional behavior within a historical perspective.

PubMed

Conti, A A; Lippi, D; Gensini, G F

2004-06-01

Obesity is an ever increasing pathological condition in Western countries. Genetic, metabolic, social and cultural factors play different roles in the varying pictures of obesity, together with nutritional behavior. This research proposes to formulate a comparison through the literary sources of the classical world, so as to determine the modalities with which obesity and nutritional habits have been perceived in the past. In Greek and Roman art, obesity often assumed the characteristics of caricature and of satire, confirmed by the elaboration of the stereotype of the sponger. Obesity generated irony and sarcasm; meanwhile the figure of the tyrant too was modelled on the physical type of the obesus, in whom the vice both of alimentary and sexual excess was concentrated. The evaluation of obesity, in the course of the time, has seen alternate phases, that propose different physical models and elaborate different aesthetical canons, but always closely related to a strong social factor as a distinctive sign: opulence. Nowadays obesity is seen, on the contrary, as an ever increasing nutritional disorder, both in prevalence and in incidence, and, to the ideal of the fat subject, very recent years have progressively substituted a different aesthetic typology, also because hyperalimentation has been qualified as a concomitant cause for a number of degenerative disorders.

Adalbert J. Volck (1828-1912): Confederate dentist, artist and anti-Lincoln satirist.

Dr. Adalbert Volck, a native of Bavaria, Germany, was a man of many talents: he was a skilled, innovative and versatile dentist, artist, artisan, craftsman, and a Confederate Civil War cartoonist and caricaturist. In 1848, after participating in a national revolution gone sour, Volck emigrated to the U.S. In 1852, Volck received his DDS degree from the Baltimore College of Dental Surgery, and subsequently, he established a life-long residency and dental practice in Baltimore. Dr. Volck gave staunch support to the spirit and force of organized dentistry. Among his professional accomplishments was his work in the early development of dental porcelain restorations. Although he was a non-combatant in the U.S. Civil War, Volck demonstrated his loyalty to the Southern cause by becoming a blockade runner; smuggler of drugs and medical supplies; "safe house" operator for Confederate soldiers and agents; Rebel spy; and personal courier for Jefferson Davis (the President of the Confederacy). The popular anti-Confederacy political cartoons of the great Thomas Nast inspired Volck to execute similar lampoons against the Union. Early in the war, Volck, through his caricatures, attacked the person and policies of President Lincoln and his Northern leaders. By using irony, sarcasm and ridicule, Volck attempted to sway popular sentiment toward the South.

"Fat is your fault". Gatekeepers to health, attributions of responsibility and the portrayal of gender in the Irish media representation of obesity.

We investigated the representation of obesity in the Irish media by conducting an inductive thematic analysis on newspaper articles (n=346) published in 2005, 2007 and 2009 sampled from six major publications. The study analysed the media's construction of gender in discussions of obesity and associated attributions of blame. Three dominant themes are discussed: the caricatured portrayal of gender, women as caregivers for others, and emotive parent-blaming for childhood obesity. Men were portrayed as a homogenous group; unaware and unconcerned about weight and health issues. Dieting and engaging in preventative health behaviours were portrayed as activities exclusively within the female domain and women were depicted as responsible for encouraging men to be healthy. Parents, specifically mothers, attracted much blame for childhood obesity and media messages aimed to shame and disgrace parents of obese children through use of emotive and evocative language. This portrayal was broadly consistent across media types and served to reinforce traditional gender roles by positioning women as primarily responsible for health. This analysis offers the first qualitative investigation into the Irish media discourse on obesity and indicates a rather traditional take on gender roles in diet and nutrition.

To analyze discourses on workplace psychological harassment in print media. Documental study on workplace psychological harassment that analyzed news stories published in three major newspapers of the State of São Paulo (southeastern Brazil) between 1990 and 2008. Discourse analysis was performed to identify discursive practices that reflect the phenomenon of psychological harassment in today's society, explanations for its occurrence and impact on workers' health. RESULT ANALYSIS: This theme emerged in the media through the dissemination of books, academic research production and laws. It was initially published in general news then in jobs and/or business sections. Discourses on compensation and precautionary business practices and coping strategies are widespread. Health-related aspects are foregone under the prevailing money-based rationale. Corporate cultures are permissive regarding psychological harassment and conflicts are escalated while working to achieve goals and results. Indifference, embarrassment, ridicule and demean were common in the news stories analyzed. The causal explanations of workplace harassment tend to have a psychological interpretation with emphasis on individual and behavioral characteristics, and minimizing a collective approach. The discourses analyzed trivialized harassment by creating caricatures of the actors involved. People apprehend its psychological content and stigmatization which contributes to making workplace harassment an accepted practice and trivializing work-related violence.

Jean-Martin Charcot and art: relationship of the "founder of neurology" with various aspects of art.

Jean-Martin Charcot (1825-1893), the "father of neurology" in France and much beyond, was also the man who established academic psychiatry in Paris, differentiating it from clinical alienism. In his teaching, he used artistic representations from previous centuries to illustrate the historical developments of hysteria, mainly with the help of his pupil Paul Richer. Charcot liked to draw portraits (in particular, sketches of colleagues during boring faculty meetings and students' examinations), caricatures of himself and others, church sculptures, landscapes, soldiers, etc. He also used this skill in his clinical and scientific work; he drew histological or anatomic specimens, as well as patients' features and demeanor. His most daring artistic experiments were drawing under the influence of hashish. Charcot's tastes in art were conservative; he displayed no affinity for the avant-gardes of his time, including impressionism, or for contemporary musicians, such as César Franck or Hector Berlioz. Léon Daudet, son of Charcot's former friend and famous writer Alphonse Daudet, described Charcot's home as a pseudo-gothic kitsch accumulation of heteroclite pieces of furniture and materials. However, as Henry Meige wrote a few years after his mentor's death, Charcot the artist remains "inseparable from Charcot the physician." © 2013 Elsevier B.V. All rights reserved.

To study phenotype-genotype correlations, ErbB/Ras pathway tumors (transgenic for ErbB2, c-Neu, mutants of c-Neu, polyomavirus middle T antigene (PyV-mT), Ras, and bi-transgenic for ErbB2/Neu with ErbB3 and with progesterone receptor) from four different institutions were histopathologically compared with Wnt pathway tumors [transgenes Wnt1, Wnt10b, dominant-negative glycogen synthase kinase 3-β, β-Catenin, and spontaneous mutants of adenomatous polyposis coli gene (Apc)]. ErbB/Ras pathway tumors tend to form solid nodules consisting of poorly differentiated cells with abundant cytoplasm. ErbB/Ras pathway tumors also have scanty stroma and lack myoepithelial or squamous differentiation. In contrast, Wnt pathway tumors exhibit myoepithelial, acinar, or glandular differentiation, and, frequently, combinations of these. Squamous metaplasia is frequent and may include transdifferentiation to epidermal and pilar structures. Most Wnt pathway tumors form caricatures of elongated, branched ductules, and have well-developed stroma, inflammatory infiltrates, and pushing margins. Tumors transgenic for interacting genes such as protein kinase CK2α (casein kinase IIα), and the fibroblast growth factors (Fgf) Int2/Fgf3 or keratinocyte growth factor (Kgf/Fgf7) also have the Wnt pathway phenotype. Because the tumors from the ErbB/Ras and the Wnt pathway are so distinct and can be readily identified using routine hematoxylin and eosin sections, we suggest that pathway pathology is applicable in both basic and clinical cancer research.

The problem of electric and magnetic microfields inside finite spherical systems of stochastically moving ions and outside them is studied. The first possible field of applications is high temperature ion clusters created by laser fields [1]. Other possible applications are nearly spherical liquid systems at room-temperature containing electrolytes. Looking for biological applications we may also think about a cell which is a complicated electrolytic system or even a brain which is a still more complicated system of electrolytic currents. The essential model assumption is the random character of charges motion. We assume in our basic model that we have a finite nearly spherical system of randomly moving charges. Even taking into account that this is at best a caricature of any real system, it might be of interest as a limiting case, which admits a full theoretical treatment. For symmetry reasons, a random configuration of moving charges cannot generate a macroscopic magnetic field, but there will be microscopic fluctuating magnetic fields. Distributions for electric and magnetic microfields inside and outside such space- limited systems are calculated. Spherical systems of randomly distributed moving charges are investigated. Starting from earlier results for infinitely large systems, which lead to Holtsmark- type distributions, we show that the fluctuations in finite charge distributions are larger (in comparison to infinite systems of the same charge density).

Discrete Neural Correlates for the Recognition of Negative Emotions: Insights from Frontotemporal Dementia

2013-01-01

Patients with frontotemporal dementia have pervasive changes in emotion recognition and social cognition, yet the neural changes underlying these emotion processing deficits remain unclear. The multimodal system model of emotion proposes that basic emotions are dependent on distinct brain regions, which undergo significant pathological changes in frontotemporal dementia. As such, this syndrome may provide important insight into the impact of neural network degeneration upon the innate ability to recognise emotions. This study used voxel-based morphometry to identify discrete neural correlates involved in the recognition of basic emotions (anger, disgust, fear, sadness, surprise and happiness) in frontotemporal dementia. Forty frontotemporal dementia patients (18 behavioural-variant, 11 semantic dementia, 11 progressive nonfluent aphasia) and 27 healthy controls were tested on two facial emotion recognition tasks: The Ekman 60 and Ekman Caricatures. Although each frontotemporal dementia group showed impaired recognition of negative emotions, distinct associations between emotion-specific task performance and changes in grey matter intensity emerged. Fear recognition was associated with the right amygdala; disgust recognition with the left insula; anger recognition with the left middle and superior temporal gyrus; and sadness recognition with the left subcallosal cingulate, indicating that discrete neural substrates are necessary for emotion recognition in frontotemporal dementia. The erosion of emotion-specific neural networks in neurodegenerative disorders may produce distinct profiles of performance that are relevant to understanding the neurobiological basis of emotion processing.

Public health researchers repeatedly represent women as a group vulnerable to ill health. This has been particularly true in the field of HIV research, where women are disproportionately affected by HIV in terms of disease burden and the social effects of the epidemic. Although women have been the focus of many prevention and treatment programs, structural barriers to implementation of these targeted programs persist. In this article we explore how high HIV-burden communities in South Africa and Zambia engage with the concepts of "woman" and "HIV risk". The data are drawn from participatory storytelling activities completed with 604 participants across 78 group discussions between December 2012 and May 2013. During discussions we found that participants made use of the core archetypal caricatures of "goodness," "badness," and "vulnerability" when describing women's HIV risk. Community members shifted between these categories in their characterizations of women, as they acknowledged the multiple roles women play, internalized different stories about women, and sometimes shifted register in the same stories. Findings suggest that health implementers, in consultation with community members, should consider the multiple positions women occupy and how this impacts the wider community's understandings of women and "risk". This approach of taking on board community understandings of the complexity of HIV risk can inform the design and implementation of HIV prevention and care programs by rendering programs more focused and in-line with community needs.

Return of the living dead: Re-reading Pierre Flourens' contributions to neurophysiology and literature.

PubMed

Levinson, Sharman

2013-01-01

Historians of neurophysiology remember Marie Jean Pierre Flourens (1794-1867) for his experimental approach to nineteenth-century debates on cortical localization and, in particular, for his successful attacks on Frantz Joseph Gall's (1758-1828) phrenology (Gall and Spurzheim, 1810-19). Whereas Gall and his colleague, Johann Gaspar Spurzheim (1776-1832), posited correlations between features of the skull and brain development and claimed to have localized character traits, competencies and temperaments in specific cortical regions, Flourens advocated cerebral equipotentiality and provided empirical as well as philosophical grounds for his theories. Flourens has also been recognized for his contributions to the understanding of the cerebellum's role in the coordination of movement, the localization of a respiratory center in the medulla oblongata, the relationship between the semicircular canals and balance, the role of the periosteum in bone growth and regeneration, and finally, the anesthetic properties of chloroform. Less known to historians of neuroscience is the fact that Pierre Flourens was not only a neurophysiologist and Secrétaire Perpetuel of the French Académie des Sciences, he was also a member of the Académie Française, France's most prestigious literary academy. Examining Flourens' contributions as a writer and, at the same time, a prime target for criticism and caricature from journalists, yields a particularly interesting example of the problematic relations between different genres of science writing and their respective publics in mid-nineteenth-century France. © 2013 Elsevier B.V.

A time for men to pull together. A manifesto for the new politics of masculinity.

PubMed

Kimbrell, A

1991-01-01

This work asserts that men as a gender are being physically and psychically devastated by the prevailing socioeconomic system. American society empowers a small percentage of men, but it causes confusion and anxiety for the majority. Men are beginning to realize that they cannot properly relate to each other or understand exploitation until they understand the extent and nature of their dispossession by economic and political institutions. The oppression of men is mirrored in the growing incidence of male self-destruction, addiction, homelessness, and hopelessness. With the advent of industrialization, millions of men who had found fulfillment in husbandry of family, community, and land were forced into an industrial system whose ultimate goal was to turn man against man in the competitive system of modern society. The traditional male role was replaced with a new image of men as autonomous, efficient, self-interested, and disconnected from nature and community. As men become more and more powerless in their own lives, they are fed more and more media images of excessive, caricatured masculinity with which to identify. It is imperative that the increasing sense of personal liberation fostered by the men's movement be channeled into political action. A brief political platform for men would include actions centered on the family and children, protection of the environment, increasing male presence in classrooms and community activities involving children, health prevention, and dismantling the military-industrial establishment. A network of activists should be established to support the men's political agenda.

The effects of paradigmatic orientations of education research and discourse

NASA Astrophysics Data System (ADS)

Smithson, John Lawrence

This essay presents an examination of contemporary disputes over methodological and epistemological foundations underlying inquiry within the field of education research; investigating the obstacles to communication and understanding found in scholarly exchanges occurring across competing paradigmatic orientations. Terminological challenges to cross-paradigmatic communication are examined, identifying three specific terminological difficulties, referred to as homonym, contextual, and onti-stemic problems. Nicholas Burbules' model of dialogue, based upon characteristics of convergence, divergence, inclusive and critical traits, is adopted and applied to a sample of cross-paradigmatic exchanges found in recent educational research journals. Examination of those exchanges reveals certain strategies associated with cross-paradigmatic communication. These strategies, labeled as trivialization, caricaturization, and re-direction, are shown to be detrimental to the mutual understanding of the interlocutors. The model is then extended to address examples of paradigmatic orientations within methodological and epistemological contexts in order to consider the relationship between the various orientations represented in the literature of interest. Methodological and epistemological orientations are shown to be loosely coupled, with unexpected shifts in paradigmatic values found among researchers' methodological and epistemological commitments. Finally, the nature of the relationship between competing paradigmatic orientations is examined, with particular attention given to four types of incommensurability (ontological, linguistic, epistemological, and values incommensurability). I conclude that, though difficult, cross-paradigmatic communication is necessary in order to provide a multi-paradigmatic perspective that takes us beyond the fractured picture of educational phenomena available from current research approaches.

The portrayal of coma in contemporary motion pictures.

Coma has been a theme of screenplays in motion pictures, but there is no information about its accuracy. The authors reviewed 30 movies from 1970 to 2004 with actors depicting prolonged coma. Accurate depiction of comatose patients was defined by appearance, the complexity of care, accurate cause of coma and probability of awakening, and appropriate compassionate discussion between the physician and family members. Twenty-two key scenes from 17 movies were rated for accuracy by a panel of neurointensivists and neuroscience nurses and then were shown to 72 nonmedical viewers. Accuracy of the scenes was assessed using a Likert Scale. Coma was most often caused by motor vehicle accidents or violence (63%). The time in a comatose state varied from days to 10 years. Awakening occurred in 18 of 30 motion pictures (60%). Awakening was sudden with cognition intact, even after prolonged time in a coma. Actors personified "Sleeping Beauty" (eyes closed, beautifully groomed). Physicians appeared as caricatures. Only two movies had a reasonable accurate representation (Dream Life of Angels and Reversal of Fortune). The majority of the surveyed viewers identified inaccuracy of representation of coma, awakenings, and conversations on the experience of being in a coma, except in 8 of the 22 scenes (36%). Twenty-eight of the 72 viewers (39%) could potentially allow these scenes to influence decisions in real life. Misrepresentation of coma and awakening was common in motion pictures and impacted on the public perception of coma. Neurologic advice regarding prolonged coma is needed.

Most peer influence research examines socialization between adolescents and their best friends. Yet, adolescents also are influenced by popular peers, perhaps due to misperceptions of social norms. This research examined the extent to which out-group and in-group adolescents misperceive the frequencies of peers' deviant, health risk, and adaptive behaviors in different reputation-based peer crowds (Study 1) and the prospective associations between perceptions of high status peers' and adolescents' own substance use over 2.5 years (Study 2). Study 1 examined 235 adolescents' reported deviant (vandalism, theft), health risk (substance use, sexual risk), and adaptive (exercise, studying) behavior, and their perceptions of Jocks', Populars', Burnouts', and Brains' engagement in the same behaviors. Peer nominations identified adolescents in each peer crowd. Jocks and Populars were rated as higher status than Brains and Burnouts. Results indicated that peer crowd stereotypes are caricatures. Misperceptions of high status crowds were dramatic, but for many behaviors, no differences between Populars'/Jocks' and others' actual reported behaviors were revealed. Study 2 assessed 166 adolescents' substance use and their perceptions of popular peers' (i.e., peers high in peer perceived popularity) substance use. Parallel process latent growth analyses revealed that higher perceptions of popular peers' substance use in Grade 9 (intercept) significantly predicted steeper increases in adolescents' own substance use from Grade 9 to 11 (slope). Results from both studies, utilizing different methods, offer evidence to suggest that adolescents misperceive high status peers' risk behaviors, and these misperceptions may predict adolescents' own risk behavior engagement.

Face-selective regions show invariance to linear, but not to non-linear, changes in facial images.

Familiar face recognition is remarkably invariant across huge image differences, yet little is understood concerning how image-invariant recognition is achieved. To investigate the neural correlates of invariance, we localized the core face-responsive regions and then compared the pattern of fMR-adaptation to different stimulus transformations in each region to behavioural data demonstrating the impact of the same transformations on familiar face recognition. In Experiment 1, we compared linear transformations of size and aspect ratio to a non-linear transformation affecting only part of the face. We found that adaptation to facial identity in face-selective regions showed invariance to linear changes, but there was no invariance to non-linear changes. In Experiment 2, we measured the sensitivity to non-linear changes that fell within the normal range of variation across face images. We found no adaptation to facial identity for any of the non-linear changes in the image, including to faces that varied in different levels of caricature. These results show a compelling difference in the sensitivity to linear compared to non-linear image changes in face-selective regions of the human brain that is only partially consistent with their effect on behavioural judgements of identity. We conclude that while regions such as the FFA may well be involved in the recognition of face identity, they are more likely to contribute to some form of normalisation that underpins subsequent recognition than to form the neural substrate of recognition per se.

Jules Bernard Luys in Charcot's penumbra.

PubMed

Parent, Martin; Parent, André

2011-01-01

Jules Bernard Luys (1828-1897) is a relatively unknown figure in 19th century French neuropsychiatry. Although greatly influenced by Jean-Martin Charcot (1825-1893), Luys worked in the shadow of the 'master of La Salpêtrière' for about a quarter of a century. When he arrived at this institution in 1862, he used microscopy and photomicrography to identify pathological lesions underlying locomotor ataxia and progressive muscular atrophy. He later made substantial contributions to our knowledge of normal human brain anatomy, including the elucidation of thalamic organization and the discovery of the subthalamic nucleus. Luys's name has long been attached to the latter structure (corps de Luys), which is at the center of our current thinking about the functional organization of basal ganglia and the physiopathology of Parkinson's disease. As head of the Maison de santé d'Ivry, Luys developed a highly original view of the functional organization of the normal human brain, while improving our understanding of the neuropathological and clinical aspects of mental illnesses. In 1886, Luys left La Salpêtrière and became chief physician at La Charité hospital. Following Charcot, whom he considered as the father of scientific hypnotism, Luys devoted the last part of his career to hysteria and hypnosis. However, Luys ventured too deeply into the minefield of hysteria. He initiated experiments as unconventional as the distant action of medication, and became one of the most highly caricatured examples of the fascination that hysteria exerted upon neurologists as well as laypersons at the end of the 19th century.

This article gives a brief overview of women's access to journalism and communication training, status of women in the media, their needs for development of skills, and portrayal of women in the media, in Bangladesh, Nepal, Pakistan, India and Sri Lanka. 5 authors from those countries contributed sections subdivided into each of these subheadings. In India, women have access to training, but their positions in the media are limited. They are often falsely stereotyped, sensationalized or exploited, or totally absent. In Sri Lanka, however, women are closer to being equal to men, in terms of training, hiring and employment, although they tend to work in women's periodicals. Women are shown in most of the advertisements, and are generally portrayed as perpetually in pursuit of glamour, food, clothes and cosmetics. Media in Nepal are comparatively new; for example, television is only 1 year old. Therefore, opportunities for women are few, and men dominate the hierarchy. Women are portrayed in the media negatively or sensationally, and used extensively in commercials. Women's position in Pakistan is limited in the cities by purdah and in rural areas by the feudal heritage, in which women are chattel. A minority of women are enrolled in journalism schools a employed in the media: those are excelling. Women are often either idealized, abused or caricatured as interested only in consumption. Women have recently entered the journalism profession in Bangladesh, now totaling 24 women. Mores do not permit women to work at night or on outside assignments. The media are liberal in Bangladesh, airing news about dowry abuse and female oppression openly. In most of the countries, women tend to work only until marriage, or afterward are limited by domestic duties.

An Analysis of Waves Underlying Grid Cell Firing in the Medial Enthorinal Cortex.

2017-08-25

Layer II stellate cells in the medial enthorinal cortex (MEC) express hyperpolarisation-activated cyclic-nucleotide-gated (HCN) channels that allow for rebound spiking via an [Formula: see text] current in response to hyperpolarising synaptic input. A computational modelling study by Hasselmo (Philos. Trans. R. Soc. Lond. B, Biol. Sci. 369:20120523, 2013) showed that an inhibitory network of such cells can support periodic travelling waves with a period that is controlled by the dynamics of the [Formula: see text] current. Hasselmo has suggested that these waves can underlie the generation of grid cells, and that the known difference in [Formula: see text] resonance frequency along the dorsal to ventral axis can explain the observed size and spacing between grid cell firing fields. Here we develop a biophysical spiking model within a framework that allows for analytical tractability. We combine the simplicity of integrate-and-fire neurons with a piecewise linear caricature of the gating dynamics for HCN channels to develop a spiking neural field model of MEC. Using techniques primarily drawn from the field of nonsmooth dynamical systems we show how to construct periodic travelling waves, and in particular the dispersion curve that determines how wave speed varies as a function of period. This exhibits a wide range of long wavelength solutions, reinforcing the idea that rebound spiking is a candidate mechanism for generating grid cell firing patterns. Importantly we develop a wave stability analysis to show how the maximum allowed period is controlled by the dynamical properties of the [Formula: see text] current. Our theoretical work is validated by numerical simulations of the spiking model in both one and two dimensions.

Why did so many German doctors join the Nazi Party early?

2012-01-01

During the Weimar Republic in the mid-twentieth century, more than half of all German physicians became early joiners of the Nazi Party, surpassing the party enrollments of all other professions. From early on, the German Medical Society played the most instrumental role in the Nazi medical program, beginning with the marginalization of Jewish physicians, proceeding to coerced "experimentation," "euthanization," and sterilization, and culminating in genocide via the medicalization of mass murder of Jews and others caricatured and demonized by Nazi ideology. Given the medical oath to "do no harm," many postwar ethical analyses have strained to make sense of these seemingly paradoxical atrocities. Why did physicians act in such a manner? Yet few have tried to explain the self-selected Nazi enrollment of such an overwhelming proportion of the German Medical Society in the first place. This article lends insight into this paradox by exploring some major vulnerabilities, motives, and rationalizations that may have predisposed German physicians to Nazi membership-professional vulnerabilities among physicians in general (valuing conformity and obedience to authority, valuing the prevention of contamination and fighting against mortality, and possessing a basic interest in biomedical knowledge and research), economic factors and motives (related to physician economic insecurity and incentives for economic advancement), and Nazi ideological and historical rationalizations (beliefs about Social Darwinism, eugenics, and the social organism as sacred). Of particular significance for future research and education is the manner in which the persecution of Jewish physician colleagues was rationalized in the name of medical ethics itself. Giving proper consideration to the forces that fueled "Nazi Medicine" is of great importance, as it can highlight the conditions and motivations that make physicians susceptible to misapplications of medicine, and guide us toward prevention of future abuse.

Tensor network state correspondence and holography

NASA Astrophysics Data System (ADS)

Singh, Sukhwinder

2018-01-01

In recent years, tensor network states have emerged as a very useful conceptual and simulation framework to study quantum many-body systems at low energies. In this paper, we describe a particular way in which any given tensor network can be viewed as a representation of two different quantum many-body states. The two quantum many-body states are said to correspond to each other by means of the tensor network. We apply this "tensor network state correspondence"—a correspondence between quantum many-body states mediated by tensor networks as we describe—to the multi-scale entanglement renormalization ansatz (MERA) representation of ground states of one dimensional (1D) quantum many-body systems. Since the MERA is a 2D hyperbolic tensor network (the extra dimension is identified as the length scale of the 1D system), the two quantum many-body states obtained from the MERA, via tensor network state correspondence, are seen to live in the bulk and on the boundary of a discrete hyperbolic geometry. The bulk state so obtained from a MERA exhibits interesting features, some of which caricature known features of the holographic correspondence of String theory. We show how (i) the bulk state admits a description in terms of "holographic screens", (ii) the conformal field theory data associated with a critical ground state can be obtained from the corresponding bulk state, in particular, how pointlike boundary operators are identified with extended bulk operators. (iii) We also present numerical results to illustrate that bulk states, dual to ground states of several critical spin chains, have exponentially decaying correlations, and that the bulk correlation length generally decreases with increase in central charge for these spin chains.

Travelling waves in a model of quasi-active dendrites with active spines

Dendrites, the major components of neurons, have many different types of branching structures and are involved in receiving and integrating thousands of synaptic inputs from other neurons. Dendritic spines with excitable channels can be present in large densities on the dendrites of many cells. The recently proposed Spike-Diffuse-Spike (SDS) model that is described by a system of point hot-spots (with an integrate-and-fire process) embedded throughout a passive tree has been shown to provide a reasonable caricature of a dendritic tree with supra-threshold dynamics. Interestingly, real dendrites equipped with voltage-gated ion channels can exhibit not only supra-threshold responses, but also sub-threshold dynamics. This sub-threshold resonant-like oscillatory behaviour has already been shown to be adequately described by a quasi-active membrane. In this paper we introduce a mathematical model of a branched dendritic tree based upon a generalisation of the SDS model where the active spines are assumed to be distributed along a quasi-active dendritic structure. We demonstrate how solitary and periodic travelling wave solutions can be constructed for both continuous and discrete spine distributions. In both cases the speed of such waves is calculated as a function of system parameters. We also illustrate that the model can be naturally generalised to an arbitrary branched dendritic geometry whilst remaining computationally simple. The spatio-temporal patterns of neuronal activity are shown to be significantly influenced by the properties of the quasi-active membrane. Active (sub- and supra-threshold) properties of dendrites are known to vary considerably among cell types and animal species, and this theoretical framework can be used in studying the combined role of complex dendritic morphologies and active conductances in rich neuronal dynamics.

The Hoopla Over the Higgs Boson: A Window into the State of Science Journalism

NASA Astrophysics Data System (ADS)

Cho, Adrian

2012-10-01

On July 4, experimenters at the European particle physics laboratory, CERN, near Geneva, Switzerland, held a special seminar in which they reported that they had at last discovered something resembling the Higgs boson, the last missing piece in particle physicists' standard model. The event drew more than 100 journalists, including myself, and the days leading up to the seminar evolved in almost a caricature of a media circus. Rumors coursed across the internet, bloggers prognosticated about what would be reported, anonymous sources whispered confidence levels to eager reporters, and on the very eve of the seminar CERN's own press office inadvertently leaked a video explaining many of the details. At a post-seminar press conference, dozens of photographers and videographers swarmed Peter Higgs, the eponymous theorist from the University of Edinburgh. Higgs even had his own handler to help him fend off the press onslaught. It was all great fun, but for a traditional journalist the event highlighted the many open questions we journalists now face. In the age of blogs and Twitter, does anybody really care that journalists try to put together fair, balanced, and accessible accounts of events? Or are people just as happy to get their information directly from researchers through their blogs or the lab through its press office? Is being first out with the story the only measure of success these days, or is there still a market for deeper analysis? I'll use the Higgs hoopla as a lens to lay out the questions as I see them. I am hoping to get the answers of the members of the audience in a discussion.

Holistic Darwinism: the new evolutionary paradigm and some implications for political science.

PubMed

Corning, Peter A

2008-03-01

Holistic Darwinism is a candidate name for a major paradigm shift that is currently underway in evolutionary biology and related disciplines. Important developments include (1) a growing appreciation for the fact that evolution is a multilevel process, from genes to ecosystems, and that interdependent coevolution is a ubiquitous phenomenon in nature; (2) a revitalization of group selection theory, which was banned (prematurely) from evolutionary biology over 30 years ago (groups may in fact be important evolutionary units); (3) a growing respect for the fact that the genome is not a "bean bag" (in biologist Ernst Mayr's caricature), much less a gladiatorial arena for competing selfish genes, but a complex, interdependent, cooperating system; (4) an increased recognition that symbiosis is an important phenomenon in nature and that symbiogenesis is a major source of innovation in evolution; (5) an array of new, more advanced game theory models, which support the growing evidence that cooperation is commonplace in nature and not a rare exception; (6) new research and theoretical work that stresses the role of nurture in evolution, including developmental processes, phenotypic plasticity, social information transfer (culture), and especially the role of behavioral innovations as pacemakers of evolutionary change (e.g., niche construction theory, which is concerned with the active role of organisms in shaping the evolutionary process, and gene-culture coevolution theory, which relates especially to the dynamics of human evolution); (7) and, not least, a broad effort to account for the evolution of biological complexity--from major transition theory to the "Synergism Hypothesis." Here I will briefly review these developments and will present a case for the proposition that this paradigm shift has profound implications for the social sciences, including specifically political theory, economic theory, and political science as a discipline. Interdependent superorganisms, it turns out, have played a major role in evolution--from eukaryotes to complex human societies.

Raising voices: How sixth graders construct authority and knowledge in argumentative essays

NASA Astrophysics Data System (ADS)

Monahan, Mary Elizabeth

This qualitative classroom-based study documents one teacher-researcher's response to the "voice" debate in composition studies and to the opposing views expressed by Elbow and Bartholomae. The author uses Bakhtin's principle of dialogism, Hymes's theory of communicative competence, as well as Ivanic's discussion of discoursally constructed identities to reconceptualize voice and to redesign writing instruction in her sixth grade classroom. This study shows how students, by redefining and then acting on that voice pedagogy in terms that made sense to them, shaped the author's understanding of what counts as "voiced" writing in non-narrative discourse. Based on a grounded-theory analysis of the twenty-six sixth graders' argumentative essays in science, the author explains voice, not as a property of writers or of texts, but as a process of "knowing together"---a collaborative, but not entirely congenial, exercise of establishing one's authority by talking with, against, and through other voices on the issue. As the results of this study show, the students' "I-Ness" or authorial presence within their texts, was born in a nexus of relationships with "rivals," "allies" and "readers." Given their teacher's injunctions to project confidence and authority in argumentative writing, the students assumed fairly adversarial stances toward these conversational partners throughout their essays. Exaggerating the terms for voiced writing built into the curriculum, the sixth graders produced essays that read more like caricatures than examples of argumentation. Their displays of rhetorical bravado and intellectual aggressiveness, however offsetting to the reader, still enabled these sixth graders to composed voiced essays. This study raises doubts about the value of urging students to sound like their "true selves" or to adopt the formal registers of academe. Students, it seems clear, stand to gain by experimenting with a range of textual identities. The author suggests that voice, as a dialogic process, involves a struggle for meaning---in concert, but also very much in conflict with---other speakers and their intentions.

Primary aldosteronism could exert a negative feedback on prorenin secretion, of possibly different magnitude, whether it is related to an aldosterone-producing adenoma (APA) or an idiopathic hyperaldosteronism (IHA). The objectives of this study were to evaluate the level of prorenin in three subgroups: APA, IHA, and essential hypertension; and the performance of the aldosterone-to-prorenin ratio (APR) for the diagnosis of an APA. Seven hundred and forty-six hypertensive patients with a standardized work-up, including a prorenin measurement, were considered. Ninety-six patients without neutral treatment and 38 patients with other forms of secondary hypertension were excluded. APA and IHA were categorized according to computed tomography scan, adrenal venous sampling, pathological analysis and improvement of hypertension after surgery. Thirty-five patients had a diagnosis of APA, 57 of IHA and 504 of essential hypertension. Prorenin was lower in APA and IHA than in essential hypertension (32.9, 40.4 and 50.3  pg/ml, respectively; P < 0.001). APR was higher in patients with APA and IHA than in those with essential hypertension (24.0, 11.8, and 4.0  pmol/l per pg/ml, respectively; P < 0.001). The APR was more discriminant than the aldosterone-to-renin ratio to identify APA compared to IHA (area under the receiver operating curve at 0.750 and 0.639, respectively; P = 0.04). The optimal cut-off values were 22  pmol/l per pg/ml for APR (sensitivity 57.0%, specificity 93.0%) and 440  pmol/l per pg/ml for aldosterone-to-renin ratio (sensitivity 54.3%, specificity 82.5%). Primary aldosteronism and particularly its most caricatural form, that is APA, seems associated with a lower level of prorenin than essential hypertension. The APR could be included in the diagnostic strategy of APA.

Multidimensional representations: The knowledge domain of germs held by students, teachers and medical professionals

NASA Astrophysics Data System (ADS)

Rua, Melissa Jo

The present study examined the understandings held by 5th, 8th, and 11th-grade students, their teachers and medical professionals about germs. Specifically, this study describes the content and structure of students' and adults' conceptions in the areas of germ contraction, transmission, and treatment of infectious and non-infectious diseases caused by microorganisms. Naturalistic and empirical research methods were used to investigate participants' conceptions. Between and within group similarities were found using data from concept maps on the topic "flu," drawings of germs, a 20 word card sort related to germs and illness, and a semi-structured interview. Concept maps were coded according to techniques by Novak and Gowan (1984). Drawings of germs were coded into four main categories (bacteria, viruses, animal cell, other) and five subcategories (disease, caricature, insect, protozoa, unclassified). Cluster patterns for the card sorts of each group were found using multidimensional scaling techniques. Six coding categories emerged from the interview transcripts: (a) transmission, (b) treatment, (c) effect of weather on illness, (d) immune response, (e) location of germs, and (f) similarities and differences between bacteria and viruses. The findings showed students, teachers and medical professionals have different understandings about bacteria and viruses and the structures of those understandings vary. Gaps or holes in the participants knowledge were found in areas such as: (a) how germs are transmitted, (b) where germs are found, (c) how the body transports and uses medicine, (d) how the immune system functions, (e) the difference between vaccines and non-prescription medicines, (f) differences that exist between bacteria and viruses, and (g) bacterial resistance to medication. The youngest students relied heavily upon personal experiences with germs rather than formal instruction when explaining their conceptions. As a result, the influence of media was evident in the students' understandings and images of microbes. Students also viewed germs as a human problem rather than seeing microorganisms as an independent member of the ecosystem. Teachers' explanations about germs varied in explicitness based on the grade level they taught while medical professionals based their understandings on formal knowledge and tended to use explicit technical language in their explanations of the phenomena.

[The jokes are vectors of stereotypes. Example of the medical profession from 220 jokes].

Sociological studies have shown the link between humor and unconscious ideas that we have of the society in which we evolve. We conducted a survey to answer the question: "What were the stereotypes of our medical profession that emerge from a transcript of jokes collected in a medical population?" Recruitment of the source population (doctors and medical students) was done through different personal and professional mailing lists, Twitter, Facebook, medical press. The inclusion period was six weeks (from June 6 to July 14, 2013). Each physician recruited received the link to our blog: http://humourmedical.overblog.com which contained a link to the questionnaire. Physicians responded to the following proposition: "tell the joke involving doctors you laugh the most". Analysis of jokes was made by three investigators. Firstly, two investigators (DM and CP) and pooled of results to generate a stereotype for each joke. Then a triangulation was made with a third investigator (BG), to determine the final stereotype. Five hundred and twelve jokes have been collected on the site and 448 were included in the analysis, representing 220 jokes. The gender of respondents was 284 men (63%) and 164 women (37%), a ratio of 1.7. One hundred and fifty-six different stereotypes were classified into six themes: 46 stereotypes 'the vicissitudes of the medical profession'; 45 'hospital', the war of the block; 34 'personality traits doctor'; 14 'psychiatrist'; 12 'physician and sexuality'; 5 'medical studies and carabin woes'. Anesthetists were represented as lazy, inveterate coffee drinkers and less awakened than their sleeping patients. Surgeons were seen as megalomaniacal, tyrannical with other professions, operating without thinking, as their brain down to a neuron. Medical students appeared docile and absurd. Psychiatrists were as crazy as their patients, sometimes passing them to the consultation and looking only at their past relationship. Other stereotypes of doctors were used: the venality, the salacious, cynicism. We showed that the stereotypes contained in the medical jokes were quite caricatured and portrayed an unflattering picture of doctors in general. These traits were necessarily marked to emphasize the humorous effect of a joke. We have not entered into the reality of these stereotypes or their social role in the relationship between doctors.

Chemical oscillators in structured media.

Evolution is a characteristic feature of living systems, and many fundamental processes in life, including the cell cycle, take place in a periodic fashion. From a chemistry perspective, these repeating phenomena suggest the question of whether reactions in which concentrations oscillate could provide a basis and/or useful models for the behavior of organisms, and perhaps even their ability to evolve. In this Account, we examine several aspects of the behavior of the prototype oscillating chemical reaction, the Belousov-Zhabotinsky (BZ) system, carried out in microemulsions, arrays of micrometer-sized aqueous droplets suspended in oil, or hydrogels. Each of these environments contains elements of the compartmentalization that likely played a role in the development of the first living cells, and within them we observe behaviors not found in the BZ reaction in simple aqueous solution. Several of these phenomena resemble traits displayed by living organisms. For example, the nanodroplets in a BZ microemulsion "communicate" with each other through a phenomenon analogous to quorum sensing in bacteria to produce a remarkable variety of patterns and waves on length scales 10(5) times the size of a single droplet. A photosensitive version can "remember" an imposed image. Larger, micrometer-sized droplets exhibit similarly rich behavior and allow for the observation and control of individual droplets. These droplets offer promise for building arrays capable of computation by varying the strength and sign of the coupling between drops. Gels that incorporate a BZ catalyst and are immersed in a solution containing the BZ reactants change their shape and volume in oscillations that follow the variation in the redox state of the catalyst. Using this phenomenon, we can construct phototactic gel "worms" or segments of gel that attract one another. Whether such systems will provide more realistic caricatures of life, and whether they can serve as useful materials will largely depend on the successful integration of various properties, including communication, motion, and memory, which we observed in separate experiments. Theoretical approaches that couple reaction and diffusion processes to mechanical and other material properties are likely to play a key role in this integration, and we describe one such approach. The evolution of systems of coupled chemical oscillators presents another challenge to the development of these systems, but one that we expect to be solved.

Roadmap for Scaling and Multifractals in Geosciences: still a long way to go ?

NASA Astrophysics Data System (ADS)

Schertzer, Daniel; Lovejoy, Shaun

2010-05-01

The interest in scale symmetries (scaling) in Geosciences has never lessened since the first pioneering EGS session on chaos and fractals 22 years ago. The corresponding NP activities have been steadily increasing, covering a wider and wider diversity of geophysical phenomena and range of space-time scales. Whereas interest was initially largely focused on atmospheric turbulence, rain and clouds at small scales, it has quickly broadened to much larger scales and to much wider scale ranges, to include ocean sciences, solid earth and space physics. Indeed, the scale problem being ubiquitous in Geosciences, it is indispensable to share the efforts and the resulting knowledge as much as possible. There have been numerous achievements which have followed from the exploration of larger and larger datasets with finer and finer resolutions, from both modelling and theoretical discussions, particularly on formalisms for intermittency, anisotropy and scale symmetry, multiple scaling (multifractals) vs. simple scaling,. We are now way beyond the early pioneering but tentative attempts using crude estimates of unique scaling exponents to bring some credence to the fact that scale symmetries are key to most nonlinear geoscience problems. Nowadays, we need to better demonstrate that scaling brings effective solutions to geosciences and therefore to society. A large part of the answer corresponds to our capacity to create much more universal and flexible tools to multifractally analyse in straightforward and reliable manners complex and complicated systems such as the climate. Preliminary steps in this direction are already quite encouraging: they show that such approaches explain both the difficulty of classical techniques to find trends in climate scenarios (particularly for extremes) and resolve them with the help of scaling estimators. The question of the reliability and accuracy of these methods is not trivial. After discussing these important, but rather short term issues, we will point out more general questions, which can be put together into the following provocative question: how to convert the classical time evolving deterministic PDE's into dynamical multifractal systems? We will argue that this corresponds to an already active field of research, which include: multifractals as generic solutions of nonlinear PDE (exact results for 1D Burgers equation and a few other caricatures of Navier-Stokes equations, prospects for 3D Burgers equations), cascade structures of numerical weather models, links between multifractal processes and random dynamical systems, and the challenging debate on the most relevant stochastic multifractal formalism, whereas there is already a rather general consent about the deterministic one.

Chemical Achievers: The Human Face of the Chemical Sciences (by Mary Ellen Bowden)

Chemical Heritage Foundation: Philadelphia, PA, 1997. viii + 180 pp. 21.6 x 27.8 cm. ISBN 0-941901-15-1. Paper. 20.00 (10.00 for high school teachers who provide documentation). At a 1991 summer workshop sponsored by the Chemical Heritage Foundation and taught by Derek A. Davenport and William B. Jensen, high school and college teachers of introductory chemistry requested a source of pictorial material about famous chemical scientists suitable as a classroom aid. CHF responded by publishing this attractive, inexpensive paperback volume, which reflects the considerable research effort needed to locate appropriate images and to write the biographical essays. Printed on heavy, glossy paper and spiral bound to facilitate conversion to overhead transparencies, it contains 157 images from pictorial collections at CHF and many other institutions on two types of achievers: the historical "greats" most often referred to in introductory courses, and scientists who made contributions in areas of the chemical sciences that are of special relevance to modern life and the career choices students will make. The pictures are intended to provide the "human face" of the book's subtitle- "to point to the human beings who had the insights and made the major advances that [teachers] ask students to master." Thus, for example, Boyle's law becomes less cold and abstract if the student can connect it with the two portraits of the Irish scientist even if his face is topped with a wig. Marie Curie can be seen in the role of wife and mother as well as genius scientist in the photographs of her with her two daughters, one of whom also became a Nobel laureate. And students are reminded of the ubiquity of the contribution of the chemical scientists to all aspects of our everyday life by the stories and pictures of Wallace Hume Carothers' path to nylon, Percy Lavon Julian's work on hormones, and Charles F. Chandler and Rachel Carson's efforts to preserve the environment. In addition to portraits (formal and informal, familiar and unfamiliar), caricatures, apparatus, patent drawings, models, manuscripts, memoranda, laboratories, and plants and buildings are featured. The book presents many images of chemists in the work settings where they actually made their discoveries. The quaint pictures of Chandler with his wash bottle, William H. Walker with his slide rule, Carl Djerassi peering at a flask without goggle protection, and Edward Goodrich Acheson with his omnipresent cigar evoke a bygone era that will induce nostalgia in instructors and curiosity or disbelief in students. Many of the 80 featured chemists are minority scientists; 10 are women (Dorothy Crowfoot Hodgkin, Marie Curie, Iréne Joliot-Curie, Mme. Lavoisier, Rosalind Franklin, Stephanie L. Kwolek, Ellen Swallow Richards, Alice Hamilton, Rachel Carson, and Julia Brainerd Hall, whose role in her brother Charles Martin Hall's development of the electrolytic production of metal is underappreciated), and three are African-Americans (Percy Lavon Julian, Walter Lincoln Hawkins, and Henry Aaron Hill). The book's 11 sections, each prefaced with a short, helpful summary, and the number of scientists profiled in each are Forerunners, 4; Theory and Production of Gases, 4; Electrochemistry and Electrochemical Industries, 12; The Path to the Periodic Table, 9; Atomic and Nuclear Structure, 9; Chemical Synthesis, Structure, and Bonding, 9; Pharmaceuticals and the Path to Biomolecules, 10; Petroleum and Petrochemicals, 4; Plastics and Other Polymers, 6; Chemical Engineering (most of whose practitioners were unfamiliar to me), 6; and Human and Natural Environmental Concerns, 7. An extensive bibliography (five double-column pages), arranged according to these sections, includes books, articles, dissertations, collections, and oral histories. Items as recent as 1997 and even a 1998 book in press are cited. An index (three triple-column pages) facilitates location of material. Chemical Achievers is to some extent similar to Henry Monmouth Smith's long-out-of-print Torchbearers of Chemistry (Academic Press, 1949), but the quality of the illustrations and paper are much better and the text is much more detailed. The book is virtually error-free; the only one that I spotted was the misspelling of O. Bertrand Ramsay's name as Ramsey.

Virtual reality - whose reality? There is an old joke about a farmer who wanted to improve his milk yields and employed an engineer, a psychologist and a physicist to make suggestions. They all went away for a month and came back with their proposals. The engineer had measured the size of the milking stalls, the ambient temperature and the milking process. She suggested a modest rise in ambient temperature and an alteration in the pumping equipment. The psychologist decided to paint the stalls green and play a tape-recording of birdsong to the cows to make them feel more content and release their milk more easily. The physicist explained that he had decided to look at things more fundamentally: 'Let us assume that the cow is a sphere' ... he began. And that's the joke. Some people think that this is the funniest thing out - a physicist can't recognize a cow when they see one. What troubles me is that I didn't get the joke straight away. I am so used to the language and the often-ludicrous assumptions in physics that it did not seem particularly strange or funny. What did you think? The joke, for me, illustrates the essence of our problem in physics teaching. In a very real way, physics is about another world. It isn't about the real world in which ordinary people live, and they know it. Physics has its own language, its own laws and its own values. Depleted uranium has been in the news of late. It is interesting to compare the casual way in which physics teachers have discussed the possibilitiy that one atom of uranium can kill someone with the shock-horror reporting of this fact in the press. We are caricatured, sometimes for good reason, being callous, calculating, cold people - out of touch with the things that really matter. And then there's that other 'real world' - of really tough people who make serious money. Our friends who work out in the worlds of commerce and industry like to mutter, with some superiority, that teachers would never survive in the real world. So here we are, buffered from the 'reality' of commerce by kind managers, left to teach equations at the expense of moral standards ... Excuse me! Physics is the only subject that confronts real reality head on. Physics is all about how this world, this Universe, this reality works. Moral laws, government legislation and theories of economics are all well, and sometimes good, but they take place within this space we call Our Universe. Physics is real This issue of Physics Education contains lots of excellent suggestions for practical work - demonstrations of what happens, and suggestions for investigations. I hope that readers will find them useful and maybe share some good ideas of their own. We are dealing with stuff that actually happens, and that is what makes physics both significant and attractive. The joke I really hate runs 'If it moves it's biology, if it smells it's chemistry and if it doesn't work it's physics'. This is rubbish: gravity always works, in my experience, physics never gets it wrong. In the classroom, maybe a piece of equipment is broken, or the technician forgot the batteries, but we can never say truthfully that 'the experiment didn't work'. Virtual physics Last week a school governor challenged me to justify the cost of so much laboratory space and equipment when, nowadays, so much can be done using computers. Probably the best 'virtual physics' currently available is on CD-ROM. In this issue of Physics Education we have concentrated on CDs for our review section. There is lots of good material out there which can enhance our teaching with wonderful images, immediate feedback for students, and the possibility of continuously monitored differentiated work but, as I explained to the governor, I don't want to teach virtual physics - physics is very firmly, fairly and squarely in this real world (which may, of course, approximate to a sphere ... .).

Fifty years of Jaynes-Cummings physics

Greentree, Andrew D.; Koch, Jens; Larson, Jonas

2013-11-01

This special issue commemorates the 50th anniversary of the seminal paper published by E T Jaynes and F W Cummings [1], the fundamental model which they introduced and now carries their names, and celebrates the remarkable host of exciting research on Jaynes-Cummings physics throughout the last five decades. The Jaynes-Cummings model has been taking the prominent stance as the 'hydrogen atom of quantum optics' [2]. Generally speaking, it provides a fundamental quantum description of the simplest form of coherent radiation-matter interaction. The Jaynes-Cummings model describes the interaction between a single electromagnetic mode confined to a cavity, and a two-level atom. Energy is exchanged between the field and the atom, which leads directly to coherent population oscillations (Rabi oscillations) and superposition states (dressed states). Being exactly solvable, the Jaynes-Cummings model serves as a most useful toy model, and as such it is a textbook example of the physicists' popular strategy of simplifying a complex problem to its most elementary constituents. Thanks to the simplicity of the Jaynes-Cummings model, this caricature of coherent light-matter interactions has never lost its appeal. The Jaynes-Cummings model is essential when discussing experiments in quantum electrodynamics (indeed the experimental motivation of the Jaynes-Cummings model was evident already in the original paper, dealing as it does with the development of the maser), and it has formed the starting point for much fruitful research ranging from ultra-cold atoms to cavity quantum electrodynamics. In fact, Jaynes-Cummings physics is at the very heart of the beautiful experiments by S Haroche and D Wineland, which recently earned them the 2012 Nobel Prize in physics. Indeed, as with most significant models in physics, the model is invoked in settings that go far beyond its initial framework. For example, recent investigations involving multi-level atoms, multiple atoms [3, 4], multiple electromagnetic modes, arrays of coupled cavities [5-7], and optomechanical systems [8] have further enriched the physics of the Jaynes-Cummings model. From the early interests in masers and the consistent quantum description of radiation and atom-photon interaction, the Jaynes-Cummings model has evolved into a cornerstone of quantum state engineering [9]. The authors of this editorial had not been born when Jaynes and Cummings wrote their remarkable paper. It is, therefore, a special honour for us to be able to draw the reader's attention to the accompanying reminiscence contributed by Frederick Cummings where he gives us a glimpse of the early history of the Jaynes-Cummings model from his perspective [11]. By now, the original 1963 paper by Jaynes and Cummings has gathered numerous citations and, at the time of writing, the number of articles involving Jaynes-Cummings physics is approaching 15 000.1 This special issue does not attempt to review this impressive wealth of research. The interested reader, however, is urged to consult the definitive article by Shore and Knight [10] for a comprehensive review of the first 30 years of Jaynes-Cummings physics. The collection of 26 papers presented in this issue, showcases a snapshot of some of the most recent and continuing research devoted to Jaynes-Cummings physics. We begin our special issue with Professor Cumming's recollections [11]. We then have six papers on quantum information aspects of the Jaynes-Cummings model [12-17]. The next topic includes seven papers on the Dicke and generalized Jaynes-Cummings models [18-24], followed by six papers on circuit QED, which is one of the most important experimental frameworks for Jaynes-Cummings systems [25-30]. Finally, we have six papers on the extension to many cavities, the Jaynes-Cummings-Hubbard model [31-36]. The snapshot of research captured in this special issue illustrates the unifying language provided by the Jaynes-Cummings model, tying together research in a number of subfields in physics. Jaynes-Cummings physics started with the diagonalization of a 2 × 2 matrix, as Frederick Cummings points out. There is no doubt that this elegance of simplicity will continue to guide exciting new research in the decades to come.
