The elusive task of defining the character of γδ T cells has been an evolving process for immunologists since stumbling upon their existence during the molecular characterization of the α and β T cell receptor genes of their better understood brethren. Defying the categorical rules used to distinctly characterize lymphocytes as either innate or adaptive in nature, γδ T cells inhabit a hybrid world of their own. At opposing ends of the simplified spectrum of modes of antigen recognition used by lymphocytes, natural killer and αβ T cells are particularly well equipped to respond to the 'missing self' and the 'dangerous non-self', respectively. However, between these two reductive extremes, we are chronically faced with the challenge of making peace with the 'safe non-self' and dealing with the inevitable 'distressed self', and it is within this more complex realm γδ T cells excel thanks to their highly empathetic nature. This review gives an overview of the latest insights revealing the unfolding story of human γδ T cells, providing a biographical sketch of these unique lymphocytes in an attempt to capture the essence of their fundamental nature and events that influence their life trajectory. What hangs in their balance is their nuanced ability to differentiate the friends from the foe and the pathological from the benign to help us adapt swiftly and efficiently to life's many stresses.

The Biographical Encyclopedia of Astronomers is a unique and valuable resource for historians and astronomers alike. It includes approx. 1850 biographical sketches on astronomers from antiquity to modern times. It is the collective work of 430 authors edited by an editorial board of 8 historians and astronomers. This reference provides biographical information on astronomers and cosmologists by utilizing contemporary historical scholarship. The fully corrected and updated second edition adds approximately 300 biographical sketches. Based on ongoing research and feedback from the community, the new entries will fill gaps and provide expansions. In addition, greater emphasis on Russo phone astronomers and radio astronomers is given. Individual entries vary from 100 to 1500 words, including the likes of the super luminaries such as Newton and Einstein, as well as lesser-known astronomers like Galileo's acolyte, Mario Guiducci.

Full Text Available The modern world is interpreted and described in terms of an autobiographical society, in which the fundamental issues of human life are resolved in the process of an individual decision and being involved in a peculiar type of a dialog. This dialog is more and more often a dialog with oneself and an author’s vision of the world created in the confrontation with virtual reality. In this epoch context the biography is taken into account as a tool for perceiving, understanding and describing the change of the world and the human’s place in the world. Even though, the biography has functioned in social life forever, only now with the epoch of individualization, and then virtualization of life, its formative character has been noticed. Who is the subject of (autobiography? Who is it aimed at as a message and testimony of life? How is it created? Why is it constructed? Who is it constructed by? And then the questions which are behind the autobiography in the theoretical sense – What is life? How do we discover it? What is the link between telling about life and living the life? How is the telling (living about a life connected with culture and history? How does reading (interpreting about life connect with telling about life and the truth about life? Social development phases coupled with transformations within biographical reflection have been distinguished: life in a traditional world – the culture of telling about life; the birth of individualism (the individualization of experience – the culture of describing life; the discovery of identity – the culture of reading about life; life in the net and cyberspace – the culture of constructing life; the new communalism – the culture of seeking the meaning of life. Every stage of biographical reflection enables us to distinguish new forms of creating, understanding and using it in both the humanities and social life, but also in ordinary people’s life.

Full Text Available The article deals with political socialization with particular consideration of open and closed processes of biographical politicization, i.e. biographical alienation. Based on narrative-biographical and theme-oriented interviews with two survivors of the Holocaust, processes of consciousness are analyzed. Henri LEFEBVRE refers in the chapter "the lived and the living" in his third volume of the "Critique of Everyday Live" (1975 to the complexity of processes of consciousness. According to LEFEBVRE there is a dialectic between the "lived" and the "living", thus the "lived" cannot be characterized only as past actions but as past experiences, constituting dialectically the present—the "living." For LEFEBVRE there is an inescapable conflict between past experiences and present life, i.e. the past could be seen as a constituting part of the conditions of individual (and societal present consciousness. Following this line of thought, one could state that to analyze former biographical (extraordinary experiences, i.e. "the lived," is crucial to better understanding of the constitutional conditions of processes of political socialization. Thus former extraordinary biographical experiences might have an essential impact on political socialization and, therefore, on political attitudes.

In a variety of application areas, the use of simulation steering in decision making is limited at best. Research focusing on this problem suggests that most user interfaces are too complex for the end user. Our goal is to let users create and investigate multiple, alternative scenarios without the need for special simulation expertise. To simplify the specification of parameters, we move from a traditional manipulation of numbers to a sketch-based input approach. Users steer both numeric parameters and parameters with a spatial correspondence by sketching a change onto the rendering. Special visualizations provide immediate visual feedback on how the sketches are transformed into boundary conditions of the simulation models. Since uncertainty with respect to many intertwined parameters plays an important role in planning, we also allow the user to intuitively setup complete value ranges, which are then automatically transformed into ensemble simulations. The interface and the underlying system were developed in collaboration with experts in the field of flood management. The real-world data they have provided has allowed us to construct scenarios used to evaluate the system. These were presented to a variety of flood response personnel, and their feedback is discussed in detail in the paper. The interface was found to be intuitive and relevant, although a certain amount of training might be necessary.

Accurately drawing 3D objects is difficult for untrained individuals, as it requires an understanding of perspective and its effects on geometry and proportions. Step-by-step tutorials break the complex task of sketching an entire object down into easy-to-follow steps that even a novice can follow. However, creating such tutorials requires expert knowledge and is time-consuming. As a result, the availability of tutorials for a given object or viewpoint is limited. How2Sketch (H2S) addresses this problem by automatically generating easy-to-follow tutorials for arbitrary 3D objects. Given a segmented 3D model and a camera viewpoint, H2S computes a sequence of steps for constructing a drawing scaffold comprised of geometric primitives, which helps the user draw the final contours in correct perspective and proportion. To make the drawing scaffold easy to construct, the algorithm solves for an ordering among the scaffolding primitives and explicitly makes small geometric modifications to the size and location of the object parts to simplify relative positioning. Technically, we formulate this scaffold construction as a single selection problem that simultaneously solves for the ordering and geometric changes of the primitives. We generate different tutorials on man-made objects using our method and evaluate how easily the tutorials can be followed with a user study.

Computer aided design is vitally important for the modern industry, particularly for the creative industry. Fashion industry faced intensive challenges to shorten the product development process. In this paper, a methodology is proposed for sketch design based on interactive genetic algorithms. The sketch design system consists of a sketch design model, a database and a multi-stage sketch design engine. First, a sketch design model is developed based on the knowledge of fashion design to describe fashion product characteristics by using parameters. Second, a database is built based on the proposed sketch design model to define general style elements. Third, a multi-stage sketch design engine is used to construct the design. Moreover, an interactive genetic algorithm (IGA) is used to accelerate the sketch design process. The experimental results have demonstrated that the proposed method is effective in helping laypersons achieve satisfied fashion design sketches.

Full Text Available Este artigo procura traçar o percurso profissional de Eliezer Schneider, um dos primeiros brasileiros com formação acadêmica em Psicologia. Formado em Direito em 1939, pela Faculdade Nacional de Direito da antiga Universidade do Brasil (hoje UFRJ, prestou concurso para o Instituto de Psicologia daquela universidade, onde ingressou em 1941. Poucos anos depois, obteve o título de Mestre em Psicologia pela Universidade de Iowa (EUA com tese sobre as teorias emergentistas da personalidade, orientada pelo professor Gustavo Bergman. Da experiência nessa Universidade permaneceu seu interesse pelo behaviorismo, menos talvez por sua metodologia do que por sua ênfase nas situações ambientais como determinantes do comportamento humano. Seu interesse pela Psicologia, segundo seu próprio relato, surgiu com o estudo do Direito - como entender o criminoso, como caracterizar a inimputabilidade? Sua principal influência, contudo, se encontra na formação de toda uma geração de professores de Psicologia Social que, com ele, aprendemos a estender nosso olhar além do paradigma individualista e intimista que caracteriza nossa Psicologia.This article presents the professional trajectory of Eliezer Schneider, one of the first Brazilians with academic training in Psychology. Graduated in Law, in 1939, by National College of Law of the old University of Brazil (nowadays Federal University of Rio de Janeiro, he applied to a position at the Institute of Psychology of that University, being hired in 1941. Few years later, he got the Master degree by University of Iowa (USA, with a thesis about the emergentist theories of personality, under the supervision of Gustavo Bergman. Due to his experience at that University, Schneider kept his interest in behaviorism alive, perhaps not so for its methodology but for its emphasis in environmental situations as determinants of human behavior. His interest in Psychology, according to his own report, began with Law studies - how to understand the criminal, how to characterize his/her unliability? However, his main contribution relates to the training of a whole generation of Social Psychology teachers, who have learned, with him, to extend our sight beyond the paradigm of individualism and intimacy that identifies our Psychology.

Raymond Alan Plumb was born on 30 March 1948 in Ripon, Yorkshire, United Kingdom. He is not known for talking about his childhood, but we do know that he liked to sing and was part of a group called the Avocets. Alan did his undergraduate degree in Manchester, obtaining his BS Physics with I Honors in 1969. He was offered a fellowship to do his PhD at Cambridge, but he had a negative reaction to a visit there and decided to stay at Manchester, where he pursued his studies in Astronomy, completing his PhD in 1972. With a highly disengaged thesis advisor, Alan was largely self-taught as a graduate student. He studied planetary atmospheres. Toward the end of his studies, Alan participated in a summer school organized by Steve Thorpe in Bangor,Wales, where he came into contact with the broader international community in geophysical fluid dynamics. Raymond Hide became particularly influential and became Alan's mentor at the UK Meteorological Office (UKMO), where Alan worked for 4 years after receiving his PhD. Another key early influence whom Alan met then was Michael McIntyre. McIntyre's interest and encouragement were very important to Alan at that early time and would continue to be so in later years, including after his move to Australia.
On the basis of mostly unpublished sources, the author reconstructs the life of the Hungarian writer Viktor von Dirsztay (1884?-1935) who was personally acquainted with many expressionist artists and writers, e. g. with Karl Kraus, Oskar Kokoschka, Herwarth Walden, Walter Hasenclever, Hermann Broch and Arthur Schnitzler. This association puts Freud into closer proximity with the cultural avantgarde of his times than previously realized. Between 1910 and 1920 Dirsztay underwent several phases of analysis with Freud; then he was treated by Theodor Reik. The overall length of his analysis with Freud is almost unparalleled. The article discusses whether and in which way Dirsztay's writings might have been influenced by his analyses and how Freud and Reik might have drawn upon their experiences with this patient. It is argued that likely references can be discovered in both authors' theories of masochism. There is an intriguing late remark of Dirsztay's that he was "ruined by analysis".

Raissa L. Berg had a remarkable career in many respects and an impact on the study of phenotypic integration that continues to increase over 50 years after the publication of her seminal paper in that area. She was born and lived most of her life in Russia, with most of her research focused on measuring spontaneous mutation rates in Drosophila. She was forced to abandon this work during the height of Lysenko's power in Russia, so she turned temporarily to the study of correlation patterns in plants; ironically, this work has had a more enduring impact than her main body of research. She showed that floral and vegetative traits become decoupled into separate correlation 'pleiades' in plants with specialized pollinators, but floral and vegetative traits remain correlated in plants that have less specialized pollination. Unfortunately, her plant work is often mis-cited as providing evidence for increased correlations among floral traits due to selection by pollinators for functional integration, a point she never made and one that is not supported by her data. Still, many studies of correlation pleiades have been conducted in plants, with the results mostly supporting Berg's hypothesis, although more studies on species with generalized pollination are needed. © 2014 The Author(s) Published by the Royal Society.

Full Text Available The paper discusses the importance of biographical approach to managing human resources, which is especially important in the first, anticipatory stage of organizational socialization, in which interview for the job is performed. Biographical principle is based on a broader and more complex approach to the candidate, which enables him to present his working career, personal qualities, professional knowledge and skills, social skills, interests and aspirations. Biographical approach allows an individual who has applied for a certain job to reflect, identify and present their work and life path in their own way.. The organization, in turn, through the biographical method receives valid information to predict the future behavior of candidates and their performance.

The books and maps we read, the posters we pin on our walls, the TV sets and computer monitors we spend hours watching, the white (or black) boards we use to teach, all reduce our world into planar images. As a result, and through years of oblivious practice, our brain is conditioned to understand the world in two dimensions (2D) only. As structural geologists, we know that the most challenging aspect of teaching and learning structural geology is that we need to be able to mentally manipulate 2D and three-dimensional (3D) objects. Although anyone can learn through practice the art of spatial visualisation, the fact remains that the initial stages of learning structural geology are for many students very challenging, as we naively use 2D images to teach 3D concepts. While interactive 3D holography is not far away, some inexpensive tools already exist allowing us to generate interactive computer images, the free rotation, scaling and manipulation of which can help students to quickly grasp the geometry and internal architecture of 3D objects. Recently, I have experimented with SketchUp (works on Mac and Windows). SketchUp was initially released in 2000 by @Last Software, as a 3D modelling tool for architects, designers and filmmakers. It was acquired by Google in 2006 to further the development of GoogleEarth. Google released SketchUp for free, and provided a portal named 3D Warehouse for users to share their models. Google sold SketchUp to Trimble Navigation in 2012, which added Extension Warehouse for users to distribute add-ons. SketchUp models can be exported in a number of formats including .dae (digital asset exchange) useful to embed interactive 3D models into iBooks and html5 documents, and .kmz (keyhole markup language zipped) to embed interactive 3D models and cross-sections into GoogleEarth. SketchUp models can be exported into 3D pdf through the add-on SimLab, and .stl for 3D printing through the add-on SketchUp STL. A free licence is available for

Sketching is a valuable field technique to support a person's observation, recording, interpretation and communication of important features in both natural and human-made landscapes. The Singapore geography syllabus employs an inquiry approach and encourages sketching as a fundamental geographical skill. Sketching allows the learner to connect with the world through a personal and kinesthetic experience. The Earth Observatory of Singapore collaborates with the Singapore Geography Teachers' Association, Urban Sketchers, and National Institute of Education professional development to give teachers both basic sketching skills and the opportunity to develop those skills in a scaffolded environment. In Singapore, geography and geology skills overlap in content area of coastal processes, climate change, and plate tectonics with its associated natural hazards such as volcanoes, earthquakes, and tsunami. Both disciplines are interested in how people live on the Earth. Likewise, basic skills such as observing, classifying, measuring, and communicating cut across disciplines of social and natural sciences in order to analyze, synthesize, and evaluate information about the world. Hence, sketching, commonly considered an art skill, is used to further scientific thinking. This somewhat unique collaboration to develop sketching in teachers is based on the long tradition of sketches in geological field work, the newly popular urban sketching community, and professional development by a professional organization and the Singapore National Institute of Education. Workshops provide technique as well as opportunities for sketching with experts in different areas relevant to the geography curriculum.

Grounding the argument in critical theory, social studies and museum theory, the article explores the narrative function of objects in biographical exhibitions by addressing the social significance of objects in relation to biography and their relevance when presented into an exhibition display. Central is the concept of objects as ‘biographical relics’ that are culturally fetishized in biographical narratives. This raises questions about biographical reliability and the cultural role that such objects plays in exhibition narratives as bearers of reality and as metonymical icons of the biographical subject. The article considers examples of biographical exhibitions of diverse figures such as Gregor Mendel, Madame de Pompadour and Roland Barthes, and the role that personal items, but also portraits and photographs, play in them.

Soon after you begin studying the sky through your small telescope or binoculars, you will probably be encouraged by others to make sketches of what you see. Sketching is a time-honored tradition in amateur astronomy and dates back to the earliest times, when telescopes were invented. Even though we have lots of new imaging technologies nowadays, including astrophotography, most observers still use sketching to keep a record of what they see, make them better observers, and in hopes of perhaps contributing something to the body of scientific knowledge about the Moon. Some even sketch because it satisfies their artistic side. The Moon presents some unique challenges to the astronomer-artist, the Moon being so fond of tricks of the light. Sketching the Moon: An Astronomical Artist’s Guide, by five of the best lunar observer-artists working today, will guide you along your way and help you to achieve really high-quality sketches. All the major types of lunar features are covered, with a variety of sketching te...

Our research group has reconstructed why the board certified urologists Werner Forssmann (1904-1979) and Charles Huggins (1901-1997) received the Nobel Prize in physiology or medicine (1956, and 1966, respectively). But the history of "Urology and the Nobel Prize" is in fact more multifaceted than the success stories of these two laureates suggest. James Israel (1848-1926), Berlin, Félix Guyon (1831-1920), Paris, Peter J. Freyer (1852-1921), London and Edwin Beer (1876-1938), New York were nominated for the award during the first three decades of the 20th century. Their candidacies mirror trends among leading urologists during the time when urology became a specialty in its own right.

Humans have always used sketches to explain the visual world. It is a simple and straight- forward mean to communicate new ideas and designs. Consequently, as in almost every aspect of our modern life, the relatively recent major developments in computer science have highly contributed to enhancing individual sketching experience. The literature of sketch related research has witnessed seminal advancements and a large body of interest- ing work. Following up with this rich literature, this dissertation provides a holistic study on sketches through three proposed novel models including sketch analysis, transfer, and geometric representation. The first part of the dissertation targets sketch authorship recognition and analysis of sketches. It provides answers to the following questions: Are simple strokes unique to the artist or designer who renders them? If so, can this idea be used to identify authorship or to classify artistic drawings? The proposed stroke authorship recognition approach is a novel method that distinguishes the authorship of 2D digitized drawings. This method converts a drawing into a histogram of stroke attributes that is discriminative of authorship. Extensive classification experiments on a large variety of datasets are conducted to validate the ability of the proposed techniques to distinguish unique authorship of artists and designers. The second part of the dissertation is concerned with sketch style transfer from one free- hand drawing to another. The proposed method exploits techniques from multi-disciplinary areas including geometrical modeling and image processing. It consists of two methods of transfer: stroke-style and brush-style transfer. (1) Stroke-style transfer aims to transfer the style of the input sketch at the stroke level to the style encountered in other sketches by other artists. This is done by modifying all the parametric stroke segments in the input, so as to minimize a global stroke-level distance between the input and

The goal of this study was to explore two accounts for why sketching during learning from text is helpful: (1) sketching acts like other constructive strategies such as self-explanation because it helps learners to identify relevant information and generate inferences; or (2) that in addition to these general effects, sketching has more specific benefits due to the pictorial representation that is constructed. Seventy-three seventh-graders (32 girls, M = 12.82 years) were first taught how to either create sketches or self-explain while studying science texts. During a subsequent learning phase, all students were asked to read an expository text about the greenhouse effect. Finally, they were asked to write down everything they remembered and then answer transfer questions. Strategy quality during learning was assessed as the number of key concepts that had either been sketched or mentioned in the self-explanations. The results showed that at an overall performance level there were only marginal group differences. However, a more in-depth analysis revealed that whereas no group differences emerged for students implementing either strategy poorly, the sketching group clearly outperformed the self-explanation group for students who applied the strategies with higher quality. Furthermore, higher sketching quality was strongly related to better learning outcomes. Thus, the study's results are more in line with the second account: Sketching can have a beneficial effect on learning above and beyond generating written explanations; at least, if well deployed.

A biographical conception of neurosis requires a dynamical perspective of personality which may be defined as the relative stability of a person in time. The life-cycle is not merely a sequence of data but a complex pattern which can be reconstructed by all semiotic systems. But the ordinary all-purpose language is to be preferred because of its flexibility to fit even very complicated state of affairs. The narration of a life-cycle does not end in a unique version but a multiplicity of legitimate narratives. The unity of all these versions is conceived as paradigma, that means a set of similar examples. The extensional set of the paradigma shows a kind of order which may be characterized intensionally by a rule or a sense. The seeming irrationality of a neurotic symptom is caused by its belonging to a different paradigma for which there is a sense. Psychotherapy is an attempt to give the seeming irrational symptoms a specific sense and to change it in a second step.

Full Text Available A precondition for any hermeneutic analysis of biographies is that the interview partners generate life history narratives. The same applies to a counseling practice that is sensitized by biographical analysis. On the one hand, clients' narratives of their own experiences provide the counselor with information on their biographical self-constructions and the processes of the sedimentation of the experiences of their life history. On the other hand, such narratives are not only of diagnostic use for the counselor, but also contribute to the clients' self-understanding. The author works in a psychosocial counseling center for university students. The article describes the transfer and potential of a style of counseling which encourages and is sensitized by biographical narratives in the context of an institution with a specific task.

Full Text Available Historical discourse is covered with ‘blind spots’ when dealing with historical role, active contribution, and participation in general of women. This emptiness is ever more obvious with regard to categories of women alternative to the mainstream gender model. While generally women artists as internally undifferentiated and amorphous gender monolith are purely represented within art history and research of art practice, non-hetero-normative women as a deviating minority are just ‘invisible’. It’s not only about the heteronormativism and heterosexism of the mainstream art history but also about phobias of feminist theory. The basic question is when, how and why the biographical approach in art analysis remains unresponsive to biographical specifics outside the socially affirmative mainstream, and why is it important in the biographical optic to detect lost elements through sharper-focused lance.

In this paper,we address the face sketch recognition problem. Firstly, we utilize the eigenface algorithm to convert a sketch image into a synthesized sketch face image. Subsequently, considering the low-level vision problem in synthesized face sketch image .Super resolution reconstruction algorithm based on CNN(convolutional neural network) is employed to improve the visual effect. To be specific, we uses a lightweight super-resolution structure to learn a residual mapping instead of directly mapping the feature maps from the low-level space to high-level patch representations, which making the networks are easier to optimize and have lower computational complexity. Finally, we adopt LDA(Linear Discriminant Analysis) algorithm to realize face sketch recognition on synthesized face image before super resolution and after respectively. Extensive experiments on the face sketch database(CUFS) from CUHK demonstrate that the recognition rate of SVM(Support Vector Machine) algorithm improves from 65% to 69% and the recognition rate of LDA(Linear Discriminant Analysis) algorithm improves from 69% to 75%.What'more,the synthesized face image after super resolution can not only better describer image details such as hair ,nose and mouth etc, but also improve the recognition accuracy effectively.

This article is an attempt to highlight the importance of biographic research to South African nursing. The writer believes that a particular attention should be paid to the contributions of South African Black/African nurse practitioners. South Africa has produced remarkable African nurses: they range from nurse Professors and Head of the University Nursing Departments to clinical nursing specialists and nursing administrators. The writer--having used the biographical approach in his Doctoral thesis--will highlight some practical and professional issues around biographic research. For the purpose of this publication, however, discussion will be confined to defining biographic research, reviewing different types of biographies, and discussing the value of the biographical research. Furthermore, the writer will identify some biographic concepts, examine their relationships, draw inferences and (hopefully) emerge with an increased understanding of the impact of biography as scientific concept.

We present our research results in the Geoillustrator project. The project has been going for four years and is ending in March. It was aimed at developing a rapid sketching tool for generating geological illustrations and animations for understanding the processes that have led to a current subsurface configuration. The sketching tool facilitates effective dissemination of ideas, e.g. through generation of interactive geo-scientific illustrations for interdisciplinary communication and communication to decision makers, media and lay persons. This can improve work processes in early phases of oil and gas exploration where critical decisions have to be taken based on limited information. It is a challenge for involved specialists in early exploration phases to externalize their ideas, and effectively achieve consensus in multidisciplinary working groups. In these work processes, a tool for rapid sketching of geology would be very useful for expressing geological hypotheses and creating and comparing different evolution scenarios. Often, decisions are influenced by factors that are not relevant, e.g. the geologists who produce the most polished illustrations of their hypothesis have a higher probability for getting their theories through to decision makers as it is more clearly communicated. This results in a competitive advantage for geologists who are skilled in creating illustrations. Having a tool that would lift the ability of all geologists to express their ideas to an equal level would result in more alternatives and better foundation for decision making. Digital sketching will also allow capturing otherwise lost material which can constitute a large amount of mental work and ideas. The results of sketching are currently scrapped as paper or erased from the blackboard or exist only as rough personal sketches. By using a digital sketching tool, the sketches can be exported to a form usable in modelling tools used in later phases of exploration. Currently, no

Science, technology, engineering, and mathematics (STEM) disciplines commonly illustrate 3D relationships in diagrams, yet these are often challenging for students. Failing to understand diagrams can hinder success in STEM because scientific practice requires understanding and creating diagrammatic representations. We explore a new approach to improving student understanding of diagrams that convey 3D relations that is based on students generating their own predictive diagrams. Participants' comprehension of 3D spatial diagrams was measured in a pre- and post-design where students selected the correct 2D slice through 3D geologic block diagrams. Generating sketches that predicated the internal structure of a model led to greater improvement in diagram understanding than visualizing the interior of the model without sketching, or sketching the model without attempting to predict unseen spatial relations. In addition, we found a positive correlation between sketched diagram accuracy and improvement on the diagram comprehension measure. Results suggest that generating a predictive diagram facilitates students' abilities to make inferences about spatial relationships in diagrams. Implications for use of sketching in supporting STEM learning are discussed. Copyright © 2016 Cognitive Science Society, Inc.

Saving of toner/ink consumption is an important task in modern printing devices. It has a positive ecological and social impact. We propose technique for converting print-job pictures to a recognizable and pleasant color sketches. Drawing a "pencil sketch" from a photo relates to a special area in image processing and computer graphics - non-photorealistic rendering. We describe a new approach for automatic sketch generation which allows to create well-recognizable sketches and to preserve partly colors of the initial picture. Our sketches contain significantly less color dots then initial images and this helps to save toner/ink. Our bio-inspired approach is based on sophisticated edge detection technique for a mask creation and multiplication of source image with increased contrast by this mask. To construct the mask we use DoG edge detection, which is a result of blending of initial image with its blurred copy through the alpha-channel, which is created from Saliency Map according to Pre-attentive Human Vision model. Measurement of percentage of saved toner and user study proves effectiveness of proposed technique for toner saving in eco-friendly printing mode.

Full Text Available This paper proposes a simple framework for face photo-sketch synthesis. We first describe the shadow details on faces and extract the prominent facial feature by two-scale decomposition using bilateral filtering. Then, we enhance the hair and some unapparent facial feature regions by combining the edge map and hair color similarity map. Finally, we obtain the face photo sketch by adding the results of the two processes. Compared with current methods, the proposed framework demands non feature localization, training or iteration process, creating vivid hair in sketch synthesis, and process arbitrary lighting conditions of input images, especially for complex self-shadows. And more importantly, it can be easily expanded to natural scene. The effectiveness of the presented framework is evaluated on a variety of databases.
Full Text Available Sounds in our environment like voices, animal calls or musical instruments are easily recognized by human listeners. Understanding the key features underlying this robust sound recognition is an important question in auditory science. Here, we studied the recognition by human listeners of new classes of sounds: acoustic and auditory sketches, sounds that are severely impoverished but still recognizable. Starting from a time-frequency representation, a sketch is obtained by keeping only sparse elements of the original signal, here, by means of a simple peak-picking algorithm. Two time-frequency representations were compared: a biologically grounded one, the auditory spectrogram, which simulates peripheral auditory filtering, and a simple acoustic spectrogram, based on a Fourier transform. Three degrees of sparsity were also investigated. Listeners were asked to recognize the category to which a sketch sound belongs: singing voices, bird calls, musical instruments, and vehicle engine noises. Results showed that, with the exception of voice sounds, very sparse representations of sounds (10 features, or energy peaks, per second could be recognized above chance. No clear differences could be observed between the acoustic and the auditory sketches. For the voice sounds, however, a completely different pattern of results emerged, with at-chance or even below-chance recognition performances, suggesting that the important features of the voice, whatever they are, were removed by the sketch process. Overall, these perceptual results were well correlated with a model of auditory distances, based on spectro-temporal excitation patterns (STEPs. This study confirms the potential of these new classes of sounds, acoustic and auditory sketches, to study sound recognition.

Full Text Available The rebellious movement of Islamic State-Indonesian Islamic Army (DI/TII began from dissatisfaction towards the secular state of newly independent Indonesia. Abd. Qahhar Mudzakkar, the leader of DI/TII in Sulawesi and his followers revolted against the government, and subsequently formed their own Islamic government. Since Qahhar graduated from Muhammadiyah school, his theological basis in his cause to establishing an Islamc state is very prevalent. He believed that his Islamic state is to uphold the truth and to defend the religion of Allah. Thus whoever opposed his DI/TII movement would be considered infidel simply because of favoring or supporting the Indonesian government they considered secular and communist. His followers and supporters were preachers and clerics, who helped Qahhar by carrying out specific functions and positions in his Islamic state. In addition, those people played an important role in getting recognition and acceptance of Sulawesi muslim society for Islamic state campaign launched by Abdul Qahhar Mudzakkar. Without their involvement, DI/TII would never had been so popular among muslim community in Sulawesi.

Realization of precision medicine ideas requires significant research effort to be able to spot subtle differences in complex diseases at the molecular level to develop personalized therapies. It is especially important in many cases of highly heterogeneous cancers. Precision diagnostics and therapeutics of such diseases demands interrogation of vast amounts of biological knowledge coupled with novel analytic methodologies. For instance, pathway-based approaches can shed light on the way tumorigenesis takes place in individual patient cases and pinpoint to novel drug targets. However, comprehensive analysis of hundreds of pathways and thousands of genes creates a combinatorial explosion, that is challenging for medical practitioners to handle at the point of care. Here we extend our previous work on mapping clinical omics data to curated Resource Description Framework (RDF) knowledge bases to derive influence diagrams of interrelationships of biomarker proteins, diseases and signal transduction pathways for personalized theranostics. We present RDF Sketch Maps - a computational method to reduce knowledge complexity for precision medicine analytics. The method of RDF Sketch Maps is inspired by the way a sketch artist conveys only important visual information and discards other unnecessary details. In our case, we compute and retain only so-called RDF Edges - places with highly important diagnostic and therapeutic information. To do this we utilize 35 maps of human signal transduction pathways by transforming 300 KEGG maps into highly processable RDF knowledge base. We have demonstrated potential clinical utility of RDF Sketch Maps in hematopoietic cancers, including analysis of pathways associated with Hairy Cell Leukemia (HCL) and Chronic Myeloid Leukemia (CML) where we achieved up to 20-fold reduction in the number of biological entities to be analyzed, while retaining most likely important entities. In experiments with pathways associated with HCL a generated RDF

Bribes biographiques ou énoncés développés accompagnant ou non la photographie, ces écrits peuvent s’insérer dans les rubriques d’un journal de naissance du secteur de l’édition, être archivés dans un cahier au nom de l’enfant ou s’afficher sur Internet grâce au support électronique du blog. Plusieurs études qualitatives (FRANCIS, 2006, 2007, 2010 ont permis de croiser différents types de données : la structure et l’organisation de journaux de naissance, les textes réalisés par les futurs parents et parents, ainsi que des entretiens réalisés auprès des familles - parents et enfants - ayant pour objectif d’aborder les pratiques familiales autour de ces objets. Les résultats montrent que les écritures parentales donnent à voir des représentations sur la famille, l’enfance et le rôle du parent. A la frontière des « écritures du moi » et des « écrits pour autrui » (SIMONET-TENANT, 2001 ; LEJEUNE et BOGAERT, 2006 les journaux de naissance peuvent être définis comme des objets à connotation mémorielle.

Full Text Available Research purpose: Managers, when applying their leadership styles, are affected by some of their own traits. This article intends to compare the leadership styles of the managers of Zabol University of Medical Sciences with respect to Hersey and Blanchard model that was based on their biographical characteristics. Research design, approach and method: The research methodology is descriptive-causal and comparative. The data were collected from 300 individuals (124 female and 176 male participants. Main findings: No significant difference was observed between the directive, persuasive, participative and delegative leadership styles of male and female managers. However, there was a significant difference between the mean of the directive, persuasive, participative and delegative leadership styles of managers, considering their work experience, education level and field of study. Research limitations: The conservative atmosphere in university environments may affect the manager’s responses to the questionnaire; therefore, in the generalisation of the results, this issue should be taken into account. Practical implications: It is recommended to hold in-service courses for managers who have a lower education level or less work experience or have been graduated from the fields of study other than the Management major. It is also suggested to pay attention to the managers’ fields of study and managerial experiences at the time of employment. Contribution: This study enhances the quality of managers’ leadership style and consequently increases the productivity in university environments.

Entitled Portraits of the Eminent and Worthy Immortals of Zhejiang During the Ming Dynasty (You Ming yuyue san bu xiu tuzan 有明於越三不朽名賢圖贊 the book included the short biographies (with poetic panegyrics and portraits of 109 men and women of Zhang Dai’s hometown of Shaoxing, one of the epicentres of China’s élite cultural life. The book was organised according to the “Three Immortalities of Life”: moral force, meritorious service, and wise words. Zhang also included a number of his own friends and family members in this collection. This paper discusses aspects the relationship between text and image in this late-imperial Chinese work, both in the context of Zhang Dai’s practice as a biographer who had a strong visual sense and in regard to his particular historical plight as someone who had survived the collapse of one dynasty and who had lived on under its successor regime.

The infantry accounts for more than a quarter of the British Army but there is a lack of data about the social and educational background of its recruits. To provide an insight into British Army infantry recruits' personal, social and educational background prior to enlistment. The study sample consisted of infantry recruits who enlisted into the British Army School of Infantry. Each recruit completed a 95-item biographical questionnaire. Descriptive statistics were used to describe the sample in terms of demographic, physical, personal, social and educational attributes. The study sample consisted of 1000 male recruits. Over half of the recruits were consuming alcohol at a hazardous or harmful level prior to enlistment and 60% of recruits had used cannabis prior to joining the Army. Academic attainment was low, with the majority of recruits achieving GCSE grade C and below in most subjects, with 15% not taking any examinations. Over half the recruits had been in trouble with the police and either been suspended or expelled from school. Substance misuse and poor behaviour are highly prevalent among recruits prior to enlistment. Taken alongside existing evidence that some of these problems are commonplace among personnel in regular service, the assumption that the British Army infantry is, in itself, a cause of these behaviours should be questioned. © The Author 2015.

This paper presents further experiments on intelligent retrieval in our chest X-ray image database system using 'sketches'. First, in the previous sketch extraction procedure, vertical-location-invariant thresholding and shape-oriented smoothing are newly developed to improve the precision of lung borders and rib images in each sketch, respectively. Then, two new ways for image retrieval using sketches; (1) image-description retrieval and (2) pattern-matching retrieval, are proposed. In each retrieval way, a procedure for understanding picture queries input through a sketch is described in detail. (author)
Full Text Available The article proposes a general, empirically grounded model for analyzing biographical uncertainty. The model is based on findings from a qualitative-explorative study of transforming meanings of unemployment among young people in post-Soviet Lithuania. In a first step, the particular features of the uncertainty puzzle in post-communist youth transitions are briefly discussed. A historical event like the collapse of state socialism in Europe, similar to the recent financial and economic crisis, is a generator of uncertainty par excellence: it undermines the foundations of societies and the taken-for-grantedness of related expectations. Against this background, the case of a young woman and how she responds to the novel threat of unemployment in the transition to the world of work is introduced. Her uncertainty management in the specific time perspective of certainty production is then conceptually rephrased by distinguishing three types or levels of biographical uncertainty: knowledge, outcome, and recognition uncertainty. Biographical uncertainty, it is argued, is empirically observable through the analysis of acting and projecting at the biographical level. The final part synthesizes the empirical findings and the conceptual discussion into a stratification model of biographical uncertainty as a general tool for the biographical analysis of uncertainty phenomena.

Because of the difficulties involved in learning and using 3D modeling and rendering software, many scientists hire programmers or animators to create models and animations. This both slows the discovery process and provides opportunities for miscommunication. Working with multiple collaborators, a tool was developed (based on a set of design goals) to enable them to directly construct models and animations. SketchBio is presented, a tool that incorporates state-of-the-art bimanual interaction and drop shadows to enable rapid construction of molecular structures and animations. It includes three novel features: crystal-by-example, pose-mode physics, and spring-based layout that accelerate operations common in the formation of molecular models. Design decisions and their consequences are presented, including cases where iterative design was required to produce effective approaches. The design decisions, novel features, and inclusion of state-of-the-art techniques enabled SketchBio to meet all of its design goals. These features and decisions can be incorporated into existing and new tools to improve their effectiveness.
Full Text Available Ingmar Bergman (1918–2007 wrote his autobiography The Magic Lantern (Laterna magica, 1987 5 years after he had finished his film career with Fanny and Alexander, his last feature made for the cinema screen. This arguably marked the second stage of his strictly literary career, the first being his plays for the stage in the 1940s. The Magic Lantern is of interest from an intermedial perspective in its forthright theatricalization or cinematization of the written text and the self-conscious performativity of its authorial voice. Of particular interest is the way the narrator turns into a kind of distanciated autobiographical witness, which in turn reminds the reader of the inherent narrative split in the autobiographical genre between the enunciating subject speaking from the present, and the described subject, the younger self in the past. In doing so the narrator seems to turn language itself into a performative venue: the medium of words becomes a theatrical stage or a cinematically charged mise-en-scène for memory as such.This is of course not only stylistically elegant, for what can be more natural than a film- and theater director who, as the very title of the autobiography announces, turns memories into cinematic and theatrical performances? But even more interesting is the extent to which Bergman in doing so seems to conjur forth his biographical legend, reminding the reader of who is in charge of text: the narrator becomes the director of the text, so to speak, lighting and setting the stage.Besides this artful approach, Bergman also clearly fictionalized his life in other ways, which is corroborated by the private note books and original manuscripts that the writer of this paper has gained access to.

Full Text Available The paper focuses on the stages in the development of mind in adults related to biographical self-reflection. The hypothesis of the study was that biographical self-reflection affects meaning-making, self-regulation and adaptation in the adults. The sample consisted of 480 individuals aged 25—65 years. The study measured indicators of biographical self-reflection, social psychological adaptation, life meaningfulness and self-regu- lation. We have found that in the age period of 46-65 years there is a shift from self-reflection on the path of life to self-reflection on life experience, which reinforces the influence of biographical self-reflection on the meaningfulness of life and self-regulation in the adults. Our study also revealed increases in biographical self-reflection at the beginning of age crises in adulthood (30—35, 40—45, 55—60 years when, as a result of reflective analysis, the adult realizes the need for change in his/her life.
Full Text Available Hanif Kureishi’s 2014 novel, The Last Word, involves most of the author’s idiosyncratic themes, such as ethnicity, racism, sexual identity, examination of interpersonal relationships and the crucial role of the creative imagination in human life. Its focal concern, however, is to explore the process of writing a literary biography of a living person and the character and dynamics of the relationship between the biographer and his subject - a writer. As such, the novel can be taken as being representative of biographic metafiction, a subcategory of historiographic metafiction, which, following the postmodernist questioning of our ability to know and textually represent historical truth, presents biographic writing critically or even mockingly, rendering its enthusiastic practitioners’ efforts with ironic scepticism. The aim of this article is to present The Last Word as a particular example of biographic metafiction that has all the crucial features of this genre, yet which differs from its predecessors through the complexity and thoroughness of its portrayal of the biographer-biographee relationship.

The rapid growth of motion capture data increases the importance of motion retrieval. The majority of the existing motion retrieval approaches are based on a labor-intensive step in which the user browses and selects a desired query motion clip from the large motion clip database. In this work, a novel sketching interface for defining the query is presented. This simple approach allows users to define the required motion by sketching several motion strokes over a drawn character, which requires less effort and extends the users’ expressiveness. To support the real-time interface, a specialized encoding of the motions and the hand-drawn query is required. Here, we introduce a novel hierarchical encoding scheme based on a set of orthonormal spherical harmonic (SH) basis functions, which provides a compact representation, and avoids the CPU/processing intensive stage of temporal alignment used by previous solutions. Experimental results show that the proposed approach can well retrieve the motions, and is capable of retrieve logically and numerically similar motions, which is superior to previous approaches. The user study shows that the proposed system can be a useful tool to input motion query if the users are familiar with it. Finally, an application of generating a 3D animation from a hand-drawn comics strip is demonstrated.
Full Text Available As South Africa is witnessing a maturing AIDS epidemic, the experience and impact of the disease are written ever more firmly into the biographical self-constructions of the infected. In this article, I explore typical strategies of dealing with uncertainties arising from new challenges, after the shock of ontological insecurity ensuing from the diagnosis, has been overcome. The analysis is based on contrasting interpretations of problem-centered biographical interviews with HIV-positive South African women. In the process, results have been formulated in terms of hypotheses regarding links between biographical situatedness and strategies of action. The hypotheses have been validated through case comparisons. The article highlights personal transformation, social support and the search for normality as key aspects for understanding these strategies and spells out how these are enabled, constrained and shaped within the social domains of religion, AIDS activism and township youth culture.

Sketching as a scientific practice goes beyond the simple act of inscribing diagrams onto paper. Scientists produce a wide range of representations through sketching, as it is tightly coupled to model-based reasoning. Chemists in particular make extensive use of sketches to reason about chemical phenomena and to communicate their ideas. However, the chemical sciences have a unique problem in that chemists deal with the unseen world of the atomic-molecular level. Using sketches, chemists strive to develop causal mechanisms that emerge from the structure and behavior of molecular-level entities, to explain observations of the macroscopic visible world. Interpreting these representations and constructing sketches of molecular-level processes is a crucial component of student learning in the modern chemistry classroom. Sketches also serve as an important component of assessment in the chemistry classroom as student sketches give insight into developing mental models, which allows instructors to observe how students are thinking about a process. In this paper we discuss how sketching can be used to promote such model-based reasoning in chemistry and discuss two case studies of curricular projects, CLUE and The Connected Chemistry Curriculum, that have demonstrated a benefit of this approach. We show how sketching activities can be centrally integrated into classroom norms to promote model-based reasoning both with and without component visualizations. Importantly, each of these projects deploys sketching in support of other types of inquiry activities, such as making predictions or depicting models to support a claim; sketching is not an isolated activity but is used as a tool to support model-based reasoning in the discipline.

This essay explores ways to "write together" the awkwardly jointed histories of "science" and "me dicine"--but it also includes other "arts" (in the old sense) and technologies. It draws especially on the historiography of medicine, but I try to use terms that are applicable across all of science, technology, and medicine (STM). I stress the variety of knowledges and practices in play at any time and the ways in which the ensembles change. I focus on the various relations of "science" and "medicine," as they were understood for a succession of periods--from mainly agricultural societies, through industrial societies, to our biomedical present--trying to sketch a history that encompasses daily practices and understandings as well as major conceptual and technical innovations. The model is meant to facilitate inquiry across topics and across times, including those to come.

The objective of this paper was to provide an update on NASA s current tools for design and analysis of hybrid wing body (HWB) aircraft with an emphasis on Vehicle Sketch Pad (VSP). NASA started HWB analysis using the Flight Optimization System (FLOPS). That capability is enhanced using Phoenix Integration's ModelCenter(Registered TradeMark). Model Center enables multifidelity analysis tools to be linked as an integrated structure. Two major components are linked to FLOPS as an example; a planform discretization tool and VSP. The planform discretization tool ensures the planform is smooth and continuous. VSP is used to display the output geometry. This example shows that a smooth & continuous HWB planform can be displayed as a three-dimensional model and rapidly sized and analyzed.

In early or preparatory design stages, an architect or designer sketches out rough ideas, not only about the object or structure being considered, but its relation to its spatial context. This is an iterative process, where the sketches are not only the primary means for testing and refining ideas, but also for communicating among a design team and to clients. Hence, sketching is the preferred media for artists and designers during the early stages of design, albeit with a major drawback: sketches are 2D and effects such as view perturbations or object movement are not supported, thereby inhibiting the design process. We present an interactive system that allows for the creation of a 3D abstraction of a designed space, built primarily by sketching in 2D within the context of an anchoring design or photograph. The system is progressive in the sense that the interpretations are refined as the user continues sketching. As a key technical enabler, we reformulate the sketch interpretation process as a selection optimization from a set of context-generated canvas planes in order to retrieve a regular arrangement of planes. We demonstrate our system (available at http:/geometry.cs.ucl.ac.uk/projects/2016/smartcanvas/) with a wide range of sketches and design studies. © 2016 The Author(s) Computer Graphics Forum © 2016 The Eurographics Association and John Wiley & Sons Ltd.

Background Intensive care unit survivors face many physical and psychological difficulties during their recovery following discharge from hospital. These difficulties can significantly affect their quality of life. Healthcare providers and survivors' families often do not understand what recovery means in this population, which may affect the support provided. Aim To consider the potential of the biographical method in helping to create stories that illustrate recovery in intensive care survivors and other populations. Discussion This paper identifies how the biographical approach has provided survivors with a way to uncover the hidden parts of their lives through diaries and interviews, and reveal the hidden stories of intensive care survivorship and recovery. Conclusion The application of the biographical method enabled stories to be created that identified the disruption survivors encounter as they struggle to appear recovered. Implications for practice The biographical method can illuminate experiences uncaptured by other methods. This insight into recovery journeys can help healthcare practitioners and family members to understand and recognise the need for support during recovery.

Full Text Available The paper considers the first case of using polygraph («lie detector» in the history of Russia for diagnosing possible simulation of auto amnesia symptoms (biographical amnesia. In recent years, the number of cases of biographical amnesia have increased greatly. Today there are several scientific concepts to explain the amnesia of biographical information using a number of approaches. Some psychiatrists believe that the existence of specified disorder is false. The appeal of scientists to the method of psychophysiological research using the polygraph to diagnose possible simulation of auto amnesia is due to the fact that the object of such research is human memory, i.e. mental process of influenced by different types of amnesia. This paper describes basic provisions of carrying out technology research for diagnosing possible cases of simulating symptoms of biographical amnesia, highlighting the progress in detail, conditions and results of the performed experiment that showed that the functional status of the patient was unsuitable for using the polygraph. Therefore, to reach a conclusion about the simulation of the symptoms of the disease is not possible. The most probable causes of this result deal with the assumption about patient taking therapeutically potent drugs that produce a pronounced anti-anxiety effect. Reexamination after the expiration of pharmacological drug term is recommended. The paper is of practical interest to psychiatrists, experts in the field of medical and clinical psychology, polygraph practitioners.

Monte Carlo (MC) simulations are widely used in positron emission tomography (PET) for optimizing detector design, acquisition protocols, and evaluating corrections and reconstruction methods. PeneloPET is a MC code based on PENELOPE, for PET simulations which considers detector geometry, acquisition electronics and materials, and source definitions. While PeneloPET has been successfully employed and validated with small animal PET scanners, it required a proper validation with clinical PET scanners including time-of-flight (TOF) information. For this purpose, we chose the family of Biograph PET/CT scanners: the Biograph True-Point (B-TP), Biograph True-Point with TrueV (B-TPTV) and the Biograph mCT. They have similar block detectors and electronics, but a different number of rings and configuration. Some effective parameters of the simulations, such as the dead-time and the size of the reflectors in the detectors, were adjusted to reproduce the sensitivity and noise equivalent count (NEC) rate of the B-TPTV scanner. These parameters were then used to make predictions of experimental results such as sensitivity, NEC rate, spatial resolution, and scatter fraction (SF), from all the Biograph scanners and some variations of them (energy windows and additional rings of detectors). Predictions agree with the measured values for the three scanners, within 7% (sensitivity and NEC rate) and 5% (SF). The resolution obtained for the B-TPTV is slightly better (10%) than the experimental values. In conclusion, we have shown that PeneloPET is suitable for simulating and investigating clinical systems with good accuracy and short computational time, though some effort tuning of a few parameters of the scanners modeled may be needed in case that the full details of the scanners studied are not available.

knowledge of the greenhouse effect (e.g. direction of re-emission of infrared energy from greenhouse gas) are significantly more likely to be answered correctly by students who also produce expert-like concept sketch items than by students who don't include this aspect in their sketch and don't answer the multiple choice questions correctly. This difference is not as apparent for less technical multiple-choice questions (e.g. type of radiation emitted by Sun). Our findings explore the formation of student's mental models throughout different interventions and how well the different assessment techniques used in this study represent the student understanding of the overall concept.
Full Text Available Reinterpretation is one of the activities that occur in visualization the role of reinterpretation is restructuring half form idea and it can be performed with applying sketch as a useful tool and creation development evaluation communication and sharing of ideas can be facilitated by sketching. Reinterpretation basically is the outcome of the lateral thinking process. Investigating of the reinterpretation of some designers indicate that externalizing a design may not be the solitary approach of designing visually and for expert architects sketching is not a crucial action in the early stages of conceptual designing. Moreover experts could progress in design by thinking only. However novice students have problem in reinterpreting patterns in their mental image whether tools such as sketch could help in the better performance of the reinterpretation process. This paper raises a fundamental question that if the sketch of novice students can support their mental imagery in order to answer this question this paper uses documentary method to investigate the previous studies in this field. Finally in accordance to the weakness of novices sketches this study concluded that their sketches could not support their mental imagery.
This chapter introduces Teddy, a sketch-based modeling system to quickly and easily design freeform models such as stuffed animals and other rotund objects. The user draws several 2D freeform strokes interactively on the screen and the system automatically constructs plausible 3D polygonal surfaces. Our system supports several modeling operations, including the operation to construct a 3D polygonal surface from a 2D silhouette drawn by the user: it inflates the region surrounded by the silhouette making a wide area fat, and a narrow area thin. Teddy, our prototype system, is implemented as a Java program, and the mesh construction is done in real-time on a standard PC. Our informal user study showed that a first-time user masters the operations within 10 minutes, and can construct interesting 3D models within minutes. We also report the result of a case study where a high school teacher taught various 3D concepts in geography using the system.
Nobel laureate Erwin Schrödinger's What is Life? is one of the great science classics of the twentieth century. A distinguished physicist's exploration of the question which lies at the heart of biology, it was written for the layman, but proved one of the spurs to the birth of molecular biology and the subsequent discovery of the structure of DNA. The philosopher Karl Popper hailed it as a 'beautiful and important book' by 'a great man to whom I owe a personal debt for many exciting discussions'. It appears here together with Mind and Matter, his essay investigating a relationship which has eluded and puzzled philosophers since the earliest times. Schrodinger asks what place consciousness occupies in the evolution of life, and what part the state of development of the human mind plays in moral questions. Brought together with these two classics are Schrödinger's autobiographical sketches, published and translated here for the first time. They offer a fascinating fragmentary account of his life as a backgro...
Full Text Available Three major causes of the importance of entrepreneurship are making wealth, developing technology and creating productive employment. It is generally believed that a revolution is needed for entrepreneurship to take place in societies nowadays. Thus, the present study aims at investigation of the biographical characteristics and explanation of its relation to entrepreneurial spirit at Mazandaran university students. The data collection instrument was a related questionnaire with the reliability level of 0.90, and the collected data related to the examined variables were analyzed by using T-Student and ANOVA Tests. The results explained and determined that, except age, other biographical characteristics including gender, marital status, employment, birth arrangement, parents‟ education level, did not have any meaningful relationship with the entrepreneurial spirit. Finally, it is the presented summary of implications for managers such as suggestions on how the managers and authorities can improve the entrepreneurial spirit among students, as well as directions for further researches.

Full Text Available In the empirical part of the following paper, professional service is shown in the context of a biographical experience of a professional—a family law attorney. In terms of method, this undertaking is precarious. Its sense lies in gaining an understanding of the biographically and historically motivated potentials and limits of professional services. A differentiated look at professional services is facilitated when you know the stories out of which specific procedures have resulted. In overcoming the crude classification of "professionalized," "not professionalized," and "de-professionalized," it is possible to further differentiate theories of professionalization (Talcott PARSONS, Ulrich OEVERMANN, Fritz SCHÜTZE. Up until now detailed examinations are missing of the genesis of concrete professional acting, even though the topic has been worked out clearly, especially in studies of teachers' work.

This article analyses and theorises the practice of biographical storytelling of HIV-positive AIDS activists in South Africa. Combining research in illness narratives, studies of emotions in social activism and analysis of global health institutions in Africa, I explore how biographical self-narrations are deployed to facilitate access to resources and knowledge and thus acquire material and symbolic value. I illustrate my argument through the analysis of the case of an AIDS activist who became a professional biographical storyteller. Based on the analysis which I claim to represent wider dynamics in human-rights-based health activism in the Global South, I propose the concept of narrative economies by which I mean the set of exchange relationships within which biographical self-narrations circulate and produce social value for individuals and organisations. © 2015 Foundation for the Sociology of Health & Illness.

Full Text Available Article is devoted to poetics of biographical and memorialistic genres of XX century, especially to the analysis of such forms of laughter as irony and parody. The basic idea is concerned with fiction of the authors, which seek to destroy Genesis and alter reality, which in no way satisfied with the artists.The purpose of the article is identifying of the specifics of literary and imaginative reconstruction of historical events in the novels of M. Kuzmin and Sasha Sokolov by analyzing specifications of its narration.Method or the methodology of work: Among research material are M. Kuzmin’s novel "A wonderful life of Joseph Balsamo, count Cagliostro" and Sasha Sololov’s novel "Palisandria". Analyzing the texts of works on the researched topic were used comparative-historical, historical-biographical and structural methods.Results: Our study suggests that irony and parody in biographical and memorialistic genres of XX century have integrated, multifunctional meaning. Analysis of the novels allows us to observe the transformation of traditional biographical memorialistic narration into the grotesque model of the reality. There are interesting observations of the functioning in the works such approaches as parody, travesty, illogic, allegory, etc. As a result of the use of similar artistic techniques the novels become metatext about human nature in generalPractical implications: The results of our research can be used for lectures on the history of Russian literature of XXth century, in the course "History of Russian Literature" at faculties and departments of Russian Philology institutes and universities.
Full Text Available Because of the growing number of right wing extremist youths in Germany, it has become increasingly necessary in social work to develop forms of professional practice, which deal with the orientations of these adolescents in an effective way. Current social work concepts of the work with right wing extremist youth ("accepting" versus "confrontational" approaches tend to isolate specific aspects of the problem and thus remain inadequate. Notably, there exists a lack of understanding of the complex interrelationships of right wing extremist orientations emerging from biographical processes as well as family history and social conditions, consequently creating an inability to effectively cope with these issues. This article is based on a study of the group dynamics in right wing milieus of adolescents and about the processes. It focuses especially on girls and young women (KÖTTIG, 2004. On the basis of case examples, an attempt will be made to show that the above-mentioned social work concepts are too narrow and that a "holistic," i.e. a biographical, perspective leads to deeper insights into right wing extremist orientations and activities. A biographical understanding of cases can lead to the discovery of starting points for social work interventions and can generate a process of self-understanding among the girls and young women as well. Such types of assistance make it possible for them to reflect on their political orientations in such a way that remaining in the neo-Nazi milieu can lose importance for them. A biographical approach lends itself to a transfer between doing research in the social sciences and casework in social work. URN: urn:nbn:de:0114-fqs080124

The therapeutic potential of nonpharmacologic interventions using biographical approaches at the end of life (EoL) is being increasingly recognized, but less attention is paid to processes impeding realization of this potential. In this article, Swedish and Australian researchers reflect on and problematize experiences using one biographical approach, dignity therapy (DT), in EoL care in Sweden. We use this as an example, focusing on critical examination of the process of applying DT in practice, examining frictions experienced in recruiting participants, collecting the data, and creating a biography. We discuss issues regarding agency, which became evident in the recruitment process and choices made about participation, and the power differentials manifested in the interactive process of eliciting stories and crafting them into a final product. We also raise salient questions about how research and practice with biographical approaches in EoL care might better build on and further existing knowledge to better reflect the complexities of everyday life. © The Author(s) 2014.

We present the general structure of a multi-annual research project. Our general expectancy concerns the possibilities of arts psychotherapy as a means of launching the blocked process of subjectivation with people suffering from exclusion, precarity and marginalization. The research project follows a complex research design with a sequential strategy, the first part consisting in an integrated psychosocial and clinical study using a mixed methodology. We constructed special rating scales for the analysis of the data of a semi-structured biographical interview and also for the holistic interpretation of the Rotter Blank Sentences Test, separating the associations to sentences beginning with the third and first person. The correlations between two sets of variables (biographical interview and Rotter test) were computed for the total experimental group (N=206), and for clinical subgroups. We shall analyse the matrices of correlations (Spearman's Rho) with the help of optimal scaling procedures (OVERALS). The links between traumatic biographical events and responses to the 3rd, respectively 1st person items of the Rotter test are interpreted in terms of unconscious versus conscious psychological processes and allow us analysing the expression of defence mechanisms and coping strategies. The results of the study are discussed in the light of the recent traumatogenic hypothesis of borderline functioning.
"In light of the challenges of globalization, hybridization of cultures, and transnational migration movements worldwide, some central deficits of socialization theory have been identified.

We study the problem of fine-grained sketch-based image retrieval. By performing instance-level (rather than category-level) retrieval, it embodies a timely and practical application, particularly with the ubiquitous availability of touchscreens. Three factors contribute to the challenging nature of the problem: (i) free-hand sketches are inherently abstract and iconic, making visual comparisons with photos difficult, (ii) sketches and photos are in two different visual domains, i.e. black and white lines vs. color pixels, and (iii) fine-grained distinctions are especially challenging when executed across domain and abstraction-level. To address these challenges, we propose to bridge the image-sketch gap both at the high-level via parts and attributes, as well as at the low-level, via introducing a new domain alignment method. More specifically, (i) we contribute a dataset with 304 photos and 912 sketches, where each sketch and image is annotated with its semantic parts and associated part-level attributes. With the help of this dataset, we investigate (ii) how strongly-supervised deformable part-based models can be learned that subsequently enable automatic detection of part-level attributes, and provide pose-aligned sketch-image comparisons. To reduce the sketch-image gap when comparing low-level features, we also (iii) propose a novel method for instance-level domain-alignment, that exploits both subspace and instance-level cues to better align the domains. Finally (iv) these are combined in a matching framework integrating aligned low-level features, mid-level geometric structure and high-level semantic attributes. Extensive experiments conducted on our new dataset demonstrate effectiveness of the proposed method.

Learning by lecture is a passive experience. Many innovative techniques have been presented to stimulate students to assume a more active attitude toward learning. In this study, simultaneous sketch drawing, as an interactive learning technique was applied to teach anatomy to the medical students. We reconstructed a fun interactive model of teaching anatomy as simultaneous anatomic sketching. To test the model's instruction effectiveness, we conducted a quasi- experimental study and then the students were asked to write their learning experiences in their portfolio, also their view was evaluated by a questionnaire. The results of portfolio evaluation revealed that students believed that this method leads to deep learning and understanding anatomical subjects better. Evaluation of the students' views on this teaching approach was showed that, more than 80% of the students were agreed or completely agreed with this statement that leaning anatomy concepts are easier and the class is less boring with this method. More than 60% of the students were agreed or completely agreed to sketch anatomical figures with professor simultaneously. They also found the sketching make anatomy more attractive and it reduced the time for learning anatomy. These number of students were agree or completely agree that the method help them learning anatomical concept in anatomy laboratory. More than 80% of the students found the simultaneous sketching is a good method for learning anatomy overall. Sketch drawing, as an interactive learning technique, is an attractive for students to learn anatomy.

Full Text Available Freehand sketching – as one of the methods to discover cities – plays main role to understand the image of the heritage city. It is considered as an important tool to analyze and document heritage buildings. The image produced by freehand sketching heightens awareness of these buildings. Previous studies conducted on the methods of architectural heritage documentation revealed that very little researches have been undertaken to use freehand sketching in the process of data survey and documentation. These researches break the deadlock in the textual documents and express the human experience clearly unlike other methods of documentation. Therefore, this article intends to document ten heritage buildings in the study area, Gamal Abdel Nasser street, Alexandria city, Egypt. – One of the most ancient streets in Alexandria that still maintain its old character and identity – using analytical freehand sketches, the sketches and analysis was created by the researcher. The results showed that these buildings seem homogeneous and have a common character despite their different architectural styles which means it respects each other within building regulations. Briefly, the results help to find out how freehand sketching successfully analyzes these buildings that assist the architects and planners to understand the design principles used in ancient times.

Full Text Available As background to the study, the article highlights the use of biographical surveys as a recent application in the field of sexuality; for this reason it has been an approach little used to understand socio-sexual events and transitions in men or women engaging in homoerotic practices. In this study, a retrospective survey (biographical of 408 men and 301 women between 18 and 55 years of age engaging in homoerotic practices was applied in the Colombian Coffee Axis in 2012. The information was analyzed using birth and pairing variables, a key strategy for interpreting biographical information. A review was also done of the press and literature for 1921-1985 with regards to homoeroticism. The findings show that until the 1960s, the written press in the Coffee Axis had few references to homosexuality, and any that were made were associated with loss of moral and good customs, with a call to the authorities to exercise control. In the Seventies the transvestite body emerges, associated with transgression of gender and criminality. Subsequently, the 1985-2011 period is marked by a strong institutionalization of erotic and affective life, expressed in the growing preponderance of gay bars and the internet as a setting that configures socio-sexual interactions. Similarly, there is a trend to a shorter duration of relationships between people of the same sex. In terms of pairing, 63% of women have sexual biographies permeated by heterosexuality; in men this proportion reaches 40%; men are more monogamous when they establish a same sex relationship than women (86.5% vs. 74.5 %. In it’s conclusions the study highlights the complex network of homoeroticism in a particular region, where diverse sexual practices, simultaneous and sometimes non-exclusive, interweave; this implies the overcoming of the dichotomous view of homoeroticism and heterosexuality as isolated camps.
Full Text Available In this paper three experiments and corresponding model simulations are reported that investigate the priming of famous name recognition in order to explore the structure of the part of the semantic system dealing with people. Consistent with empirical findings, novel computational simulations using Burton et al.'s interactive activation and competition model point to a conceptual distinction between how priming is initiated in single- and double-familiarity tasks, indicating that priming should be weaker or non-existent for the single-familiarity task. Experiment One demonstrates that, within a double-familiarity framework using famous names, categorial and associative priming are reliable effects. Pushing the model to the limit, it predicts that pairs of celebrities who are neither associatively- nor categorially-related but who share single biographical features, both died in a car crash for example, should prime each other. Experiment Two investigated this in a double familiarity task but the effect was not observed. We therefore simulated and realized a pairwise learning task that was conceptually similar to the double-familiarity decision task but allowed to strengthen the underlying connections. Priming based on a single biographical feature could be found both in simulations and the experiment. The effect was not due to visual or name similarity which were controlled for and participants did not report using the biographical links between the people to learn the pairs. The results are interpreted to lend further support to structural models of the memory for persons. Furthermore, the results are consistent with the idea that episodic features known about people are stored in semantic memory and are automatically activated when encountering that person.
Full Text Available This article deals with the problem of biographic parallelism as a basis for typological research. The main task is to find out similarities and differences in the works by George Orwell and Ivan Bahrianyi, all of them being based of the real facts from the writers' lives. The peculiarities of the literary interpretation of the biography of the both authors become the comparative basis for revealing of the common processes in their works. The research sheds the light on the interdependence between authors' motivations and its literary results. It also highlights the problem of genres chosen by the writers and of the dependence of this choice on the biographic facts usage. The article compares the genres of the authors' works from the point of view of their artistic motivation. The subject under study includes such books of the authors as “Burmese Days”, “Keep the Aspidistra Flying” and other by George Orwell, as well as “The Getsyman Garden”, “The Hunters and the Hunted” and others by Ivan Bahrianyi. It deals with the problem of the influence of the writers' biographic facts on their creation of the literary images and characters, as well as on the plots of the stories. The similarities between authors and their characters are revealed and this allows us to say that writers used their own lives as a source of inspiration and artistic motivation for the sake of making their stories credible. The article also raises the question of the nature of the writers' characters with authors' being their possible prototypes. In general, the article studies the parallels of George Orwell and Ivan Bahrianyi lives, trying to prove their compatibility in the typological field while both use their biographies as a creative method.

We present DrawFromDrawings, an interactive drawing system that provides users with visual feedback for assistance in 2D drawing using a database of sketch images. Following the traditional imitation and emulation training from art education, DrawFromDrawings enables users to retrieve and refer to a sketch image stored in a database and provides them with various novel strokes as suggestive or deformation feedback. Given regions of interest (ROIs) in the user and reference sketches, DrawFromDrawings detects as-long-as-possible (ALAP) stroke segments and the correspondences between user and reference sketches that are the key to computing seamless interpolations. The stroke-level interpolations are parametrized with the user strokes, the reference strokes, and new strokes created by warping the reference strokes based on the user and reference ROI shapes, and the user study indicated that the interpolation could produce various reasonable strokes varying in shapes and complexity. DrawFromDrawings allows users to either replace their strokes with interpolated strokes (deformation feedback) or overlays interpolated strokes onto their strokes (suggestive feedback). The other user studies on the feedback modes indicated that the suggestive feedback enabled drawers to develop and render their ideas using their own stroke style, whereas the deformation feedback enabled them to finish the sketch composition quickly.

A total of 750 teachers from 16 government and non-government schools from areas of contrasted socio-economic status (SES) responded to a questionnaire designed to investigate associations between selected aspects of burnout among teachers working in secondary schools in Victoria, Australia. By comparing high and low burnout groups on biographic, psychological and work pattern variables, differences between teachers experiencing high and low levels of burnout were identified. Multiple regression analyses assessed the relative importance of these variables in accounting for the variance in each of the three burnout subscales. School type was related to perceptions of stress and burnout. Higher levels of burnout were associated with poorer physical health, higher rates of absenteeism, lower self-confidence and more frequent use of regressive coping strategies. Teachers classified as experiencing high levels of burnout attributed most of the stress in their lives to teaching and reported low levels of career commitment and satisfaction. Further, teachers who recorded high levels of burnout were characterised by lower levels of the personality disposition of hardiness, lower levels of social support, higher levels of role stress and more custodial pupil control ideologies than their low-burnout counterparts. Psychological variables were found to be more significant predictors of burnout than biographical variables.

In this article we draw on Bury's theory of biographical disruption to discuss the meanings of, and emotional experiences related to, being diagnosed with breast cancer among southern Thai women. Qualitative methods, including in-depth interviewing and drawing methods, were used to collect data from 20 women with breast cancer. The women perceived breast cancer to be a rhok raai; an evil or dread disease. They believed that breast cancer would lead to death. The disruption in their biography occurred when they detected abnormalities indicating breast cancer. The women's narratives revealed their chaotic lives upon this diagnosis and the news precipitated in them shock, fear, anxiety and loss of hope. Although they experienced chaos and disruption, the women cultivated strategies that helped them cope with their experiences by accepting their fate and adhering to Buddhist beliefs and practices. Through their narratives of biographical disruption, the women in our study offer healthcare providers knowledge that could lead to an appreciation of their needs and concerns. This knowledge is crucial for health professionals who wish to provide emotional support to women who have been diagnosed with breast cancer in Thailand and elsewhere. © 2015 Foundation for the Sociology of Health & Illness.

Full Text Available The novel El jinete polaco by Antonio Muñoz Molina is a highly complex work in which the narrator mixes multiple plotlines in an effort to recreate or remember part of his family past. In the process, the collective memory of the town and people of Mágina (an allegoric space that represents the peasant life of the olive growers of southern Spain appears as a rich and contradictory montage of dreams and failures. And in a third level of discourse, the recent past of Spain also emerges through the main historic al events: the civil war, the protracted military government, and the economic development and current consolidation of democracy. In order to achieve this complex and ambitious narrative project, in El jinete polaco time is not represented as uninterrupted historical timeline but as the rich mixture of the simultaneous experiences of different life courses in terms of both values and cultural patterns in order to understand how the rapid social change affects relations between the various age groups. In other words, time is constructed as a synthesis of the biographical dimension within collective memory and major historical events. This paper seeks to point out the similarities and differences between biographical discourse, collective memory and history.
CO 0 2 -radicals stabilised in SrCO 3 are examined as an example of disorder in diamagnetic matrices containing isolated paramagnetic centers. The genesis, stabilisation and further recombination of CO - 2 is connected with a specific biographical disorder in SrCO 3 , depending on the rate of decomposition of the initial SrC 2 O 4 .H 2 O. Depending on the electronic configuration of the EPR-active ion and the structure of the matrix (interionic distances and angles between them), the biographical and intrinsic disorder may influence different parameters of the exchange-narrowed EPR singlet line. For example, Co 3 O 4 has a rigid structure, varying slightly with the preparation temperature. The disorder affects only the local zero-field splittings of the 4 A 2 state of the Co 2+ -ions, the exchange field being insensitive to it. In the more flexible structure of Fe 2 (MoO 4 ) 3 , the disorder due to small deviations from stoichiometry changes the exchange field between Fe(III) ions, while the second moment of the EPR line remains constant.

Full Text Available In this paper we present an efficient technique for sketch-based 3D modeling using automatically extracted image features. Creating a 3D model often requires a drawing of irregular shapes composed of curved lines as a starting point but it is difficult to hand-draw such lines without introducing awkward bumps and edges along the lines. We propose an automatic alignment of a user׳s hand-drawn sketch lines to the contour lines of an image, facilitating a considerable level of ease with which the user can carelessly continue sketching while the system intelligently snaps the sketch lines to a background image contour, no longer requiring the strenuous effort and stress of trying to make a perfect line during the modeling task. This interactive technique seamlessly combines the efficiency and perception of the human user with the accuracy of computational power, applied to the domain of 3D modeling where the utmost precision of on-screen drawing has been one of the hurdles of the task hitherto considered a job requiring a highly skilled and careful manipulation by the user. We provide several examples to demonstrate the accuracy and efficiency of the method with which complex shapes were achieved easily and quickly in the interactive outline drawing task.

Full Text Available Communications for information synchronization during the conceptual design phase require designers to employ more intuitive digital design tools. This paper presents findings of a feasibility study for using VR 3D sketching interface in order to replace current non-intuitive CAD tools. We used a sequential mixed method research methodology including a qualitative case study and a cognitive-based quantitative protocol analysis experiment. Foremost, the case study research was conducted in order to understand how novice designers make intuitive decisions. The case study documented the failure of conventional sketching methods in articulating complicated design ideas and shortcomings of current CAD tools in intuitive ideation. The case study’s findings then became the theoretical foundations for testing the feasibility of using VR 3D sketching interface during design. The latter phase of study evaluated the designers’ spatial cognition and collaboration at six different levels: "physical-actions", "perceptualactions", "functional-actions", "conceptual-actions", "cognitive synchronizations", and "gestures". The results and confirmed hypotheses showed that the utilized tangible 3D sketching interface improved novice designers’ cognitive and collaborative design activities. In summary this paper presents the influences of current external representation tools on designers’ cognition and collaboration as well as providing the necessary theoretical foundations for implementing VR 3D sketching interface. It contributes towards transforming conceptual architectural design phase from analogue to digital by proposing a new VR design interface. The paper proposes this transformation to fill in the existing gap between analogue conceptual architectural design process and remaining digital engineering parts of building design process hence expediting digital design process.

In this article, I interrogate the changing forms that may be fundamental to transformative learning and how these are best chronicled and understood. Drawing on auto/biographical narrative research, I challenge the continuing primacy of a kind of overly disembodied, decontextualized cognition as the basis of transformation. Notions of epistemic…
The quantitative and the qualitative results were complementary in demonstrating the effectiveness of the biographic-narrative intervention. As predicted, there was a specific treatment effect with a significant and stable improvement in QoL. Analysis of the semi-structured interviews indicated that through the approach the participants’ sense of self changed. The findings provide foundations for future work into intervention.

Personal identity depends on synchronic coherence and diachronic continuity of the self. Autobiographical remembering and autobiographical knowledge as well as the stability of bodily integrity, of social roles, of significant others and of physical and sociocultural environment have been suggested as supporting a pre-reflective sense of self-continuity. Stark biographical discontinuities or disruptions in these areas may destabilise the sense of self-continuity. To test the hypothesis that autobiographical reasoning in life narratives helps to compensate the effects of biographical discontinuities on the sense of self-continuity, life narratives of a lifespan sample with the ages of 16, 20, 24, 28, 44 and 69 (N = 150, 78 female) were investigated. Results confirm that if, and only if there have been biographical disruptions in the past four years, then autobiographical reasoning correlates positively with a sense of self-continuity. The findings contradict the thesis that mere remembering of past episodes is sufficient to maintain a sense of self-continuity under conditions of biographical change.
Full Text Available Pierre Mertens’ novel Les éblouissements, published in 1987, is a fictionalised biography of a famous German poet Gottfried Benn, who made the biggest mistake of his life agreeing to support the National Socialist regime during several months. Mertens reconstructs the poet’s life trying to understand the reasons of his commitment, considered by the intellectuals of that time to be a betrayal. Mertens’ text is an illustration of the relationship between the individual and the historical past and, at the same time, an example of problemising the biographical factor in relation to Great History. Playing with the double signification of the word ‘éblouissement’, the novelist offers his own interpretation of the German poet’s double life.

In one of the first open diffusion experiments with young children, a tool-use task that afforded multiple methods to extract an enclosed reward and a child model habitually using one of these methods were introduced into different playgroups. Eighty-eight children, ranging in age from 2 years 8 months to 4 years 5 months, participated. Measures were taken of how alternative methods and success in extracting rewards spread across the different groups. Additionally, the biographic, social, cognitive, and temperamental predictors of social learning were investigated. Variations in social learning were related to age, popularity, dominance, impulsivity, and shyness, while other factors such as sex, theory of mind, verbal ability, and even imitativeness showed little association with variance in children's information acquisition. © 2012 The Authors.

This paper is located within work in urban studies about the significance of contact with difference as a means for reducing prejudice and achieving social change. Recent approaches, influenced by theories of affect, have emphasised non-conscious everyday negotiations of difference in the city. In this paper it is argued that such approaches lose sight of the significance of the subject: of the reflective judgements of ‘others’ made by individuals; of our ability to make decisions around the control of our feelings and identifications; and of the significance of personal pasts and collective histories in shaping the ways we perceive and react to encounters. Rather, this paper uses a biographical approach focusing on interviewees’ narratives of encounter. Through its attention to processes of mobility and emplacement, it contributes to debates about when contact with difference matters by highlighting the importance of everyday social normativities in the production of moral dispositions.

Full Text Available This article focuses on the biographical dimension of the processes of developing political awareness and the significance for consistency in political action. It is based on a single case study which was developed within an oral history project in the 1980s. A new reconstruction of a worker's narrative about his refusal to serve in the army and subsequent flight during the National-Socialist period shows how personal desires for change and institutionalized political patterns of interpretation and action are intertwined. The protagonist could cope with times of extremely restricted latitude for action, as was the case in the Nazi era, acquiring personal learning or crisis management skills as long as there was hope for future emancipation and social integration. In the postwar period the dissipation of this perspective lead to a reduction in his individual ability to take political action. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1102118

The term "nonorganic hearing loss" (NOHL) (pseudohypacusis, functional or psychogenic hearing loss) describes a hearing loss without a detectable corresponding pathology in the auditory system. It is characterized by a discrepancy between elevated pure tone audiometry thresholds and normal speech discrimination. The recommended audiological management of NOHL in children comprises history taking, diagnosis, and counseling. According to the literature, prognosis depends on the severity of the patient's school and/or personal problems. Routine referral to a child psychiatrist is discussed as being controversial. The clinical history of 34 children with NOHL was retrospectively evaluated. In 15 children, follow up audiometry was performed. Results of biographical history, subjective and objective audiometry, additional speech and language assessment, psychological investigations and follow up audiometry are presented and discussed. The prevalence of NOHL was 1.8% in children with suspected hearing loss. Mean age at diagnosis was 10.8 years. Girls were twice as often affected as boys. Patient history showed a high prevalence of emotional and school problems. Pre-existing organic hearing loss can be worsened by nonorganic causes. Children with a fast recovery of hearing thresholds (n=6) showed a high rate (4/6) of family, social and emotional problems. In children with continuous threshold elevation (n=9), biographical history showed no recognizable or obvious family, social or emotional problems; learning disability (4/9) was the most frequently presented characteristic. Due to advances in objective audiometry, the diagnosis of NOHL is less challenging than management and counseling. Considering the high frequency of personal and school problems, a multidisciplinary setting is helpful. On the basis of our results, drawing conclusions from hearing threshold recovery on the severity of underlying psychic problems seems inappropriate. As a consequence, a referral to a

Full Text Available This study aims to describe the sketches of Minangkabau society before independence as reflected in Nur St. Iskandar’s and Hamka’s novels. In Iskandar’s novel, a good character in society is a Western educated person who is an employer at the Dutch office. In Hamka’s novel, a good character of society is one holding religious (Islam education and working as an entrepreneur. Both characters reflect a social group who tends to demonstrate rationality and good attitude, but opposes any tradition that contradicts religion (Islam. The life sketches reflected in Nur St. Iskandar’s and Hamka’s novels also have impacts on the Minangkabau societies’ way of thinking.
Generation of shear waves in shallow seismic investigations (those to depths usually less than 100 m) can be accomplished by horizontally striking with a hammer either the end of a wood plank or metal structure embedded at the ground surface. The dimensioned sketches of this report are of a steel, hammer-impact, spiked-base, shear-wave source. It has been used on outcrops and in a desert environment and for conducting experiments on the effect of rotating source direction.

How to effectively retrieve desired 3D models with simple queries is a long-standing problem in computer vision community. The model-based approach is quite straightforward but nontrivial, since people could not always have the desired 3D query model available by side. Recently, large amounts of wide-screen electronic devices are prevail in our daily lives, which makes the sketch-based 3D shape retrieval a promising candidate due to its simpleness and efficiency. The main challenge of sketch-based approach is the huge modality gap between sketch and 3D shape. In this paper, we proposed a novel deep correlated holistic metric learning (DCHML) method to mitigate the discrepancy between sketch and 3D shape domains. The proposed DCHML trains two distinct deep neural networks (one for each domain) jointly, which learns two deep nonlinear transformations to map features from both domains into a new feature space. The proposed loss, including discriminative loss and correlation loss, aims to increase the discrimination of features within each domain as well as the correlation between different domains. In the new feature space, the discriminative loss minimizes the intra-class distance of the deep transformed features and maximizes the inter-class distance of the deep transformed features to a large margin within each domain, while the correlation loss focused on mitigating the distribution discrepancy across different domains. Different from existing deep metric learning methods only with loss at the output layer, our proposed DCHML is trained with loss at both hidden layer and output layer to further improve the performance by encouraging features in the hidden layer also with desired properties. Our proposed method is evaluated on three benchmarks, including 3D Shape Retrieval Contest 2013, 2014, and 2016 benchmarks, and the experimental results demonstrate the superiority of our proposed method over the state-of-the-art methods.

Full Text Available A system for retrieving video sequences created by tracking humans in a smart environment, by using spatial queries, is presented. Sketches made with a pointing device on the floor layout of the environment are used to form queries corresponding to locomotion patterns. The sketches are analyzed to identify the type of the query. Directional search algorithms based on the minimum distance between points are applied for finding the best matches to the sketch. The results are ranked according to the similarity and presented to the user. The system was developed in two stages. An initial version of the system was implemented and evaluated by conducting a user study. Modifications were made where appropriate, according to the results and the feedback, to make the system more accurate and usable. We present the details of the initial system, the user study and the results, and the modifications thus made. The overall accuracy of retrieval for the initial system was approximately 93%, when tested on a collection of data from a real-life experiment. This is improved to approximately 97% after the modifications. The user interaction strategy and the search algorithms are usable in any environment for automated retrieval of locomotion patterns. The subjects who evaluated the system found it easy to learn and use. Their comments included several prospective applications for the user interaction strategy, providing valuable insight for future directions.

We present Visualization-by-Sketching, a direct-manipulation user interface for designing new data visualizations. The goals are twofold: First, make the process of creating real, animated, data-driven visualizations of complex information more accessible to artists, graphic designers, and other visual experts with traditional, non-technical training. Second, support and enhance the role of human creativity in visualization design, enabling visual experimentation and workflows similar to what is possible with traditional artistic media. The approach is to conceive of visualization design as a combination of processes that are already closely linked with visual creativity: sketching, digital painting, image editing, and reacting to exemplars. Rather than studying and tweaking low-level algorithms and their parameters, designers create new visualizations by painting directly on top of a digital data canvas, sketching data glyphs, and arranging and blending together multiple layers of animated 2D graphics. This requires new algorithms and techniques to interpret painterly user input relative to data "under" the canvas, balance artistic freedom with the need to produce accurate data visualizations, and interactively explore large (e.g., terabyte-sized) multivariate datasets. Results demonstrate a variety of multivariate data visualization techniques can be rapidly recreated using the interface. More importantly, results and feedback from artists support the potential for interfaces in this style to attract new, creative users to the challenging task of designing more effective data visualizations and to help these users stay "in the creative zone" as they work.

Novice designers produced a sequence of sketches while inventing a logo for a novel brand of soft drink. The sketches were scored for the presence of specific objects, their local features and global composition. Self-assessment scores for each sketch and art critics' scores for the end products were collected. It was investigated whether the design evolves in an essentially random fashion or according to an overall heuristic. The results indicated a macrostructure in the evolution of the design, characterized by two stages. For the majority of participants, the first stage is marked by the introduction and modification of novel objects and their local and global aspects; the second stage is characterized by changes in their global composition. The minority that showed the better designs has a different strategy, in which most global changes were made in the beginning. Although participants did not consciously apply these strategies, their self-assessment scores reflect the stages of the process. 2005 Lawrence Erlbaum Associates, Inc.

Integrated clinical whole-body PET/MR systems were introduced in 2010. In order to bring this technology into clinical usage, it is of great importance to compare the performance with the well-established PET/CT. The aim of this study was to evaluate PET performance, with focus on image quality, on Siemens Biograph mMR (PET/MR) and Siemens Biograph mCT (PET/CT). A direct quantitative comparison of the performance characteristics between the mMR and mCT system was performed according to National Electrical Manufacturers Association (NEMA) NU 2-2007 protocol. Spatial resolution, sensitivity, count rate and image quality were evaluated. The evaluation was supplemented with additional standardized uptake value (SUV) measurements. The spatial resolution was similar for the two systems. Average sensitivity was higher for the mMR (13.3 kcps/MBq) compared to the mCT system (10.0 kcps/MBq). Peak noise equivalent count rate (NECR) was slightly higher for the mMR (196 kcps @ 24.4 kBq/mL) compared to the mCT (186 kcps @ 30.1 kBq/mL). Scatter fractions in the clinical activity concentration range yielded lower values for the mCT (34.9 %) compared to those for the mMR (37.0 %). Best image quality of the systems resulted in approximately the same mean hot sphere contrast and a difference of 19 percentage points (pp) in mean cold contrast, in favour of the mCT. In general, point spread function (PSF) increased hot contrast and time of flight (TOF) increased both hot and cold contrast. Highest hot contrast for the smallest sphere (10 mm) was achieved with the combination of TOF and PSF on the mCT. Lung residual error was higher for the mMR (22 %) than that for the mCT (17 %), with no effect of PSF. With TOF, lung residual error was reduced to 8 % (mCT). SUV was accurate for both systems, but PSF caused overestimations for the 13-, 17- and 22-mm spheres. Both systems proved good performance characteristics, and the PET image quality of the mMR was close to that of the m

Full Text Available The musical production of Claudio Santoro between 1947 and 1957, the period in which he embarked on four trips to Eastern Europe and former countries of the Soviet Union, is generally linked by musicology to the nationalist-popular thematic in relationship to the dominant strand on the eastern side of the Iron Curtain known as "socialist realism". Nevertheless, in this article we reflect on how Santoro's epistolary and autobiographical writing that articulates some of his musical pieces--without disregard to the this aesthetic-ideological connection--promoted in fact a triple imbrication: the reiteration of neoclassical elements; the insertion of musical expressions associated to subalternized groups in Brazil (“batuques”, “frevos”, etc. from the viewpoint of the exotic and/or the folklore; and the concomitance of everyday urban and industrial sounds on his cinematic soundtracks. Accordingly, Claudio Santoro represents a composer of singular importance, because through him it is possible to interpret the combinatory possibilities of music, sometimes quite unusual and performative in its relationship to culture, history and biographical pathways. To carry out such an analysis, this article referred to letters sent by Claudio Santoro to the musician and composer Nadia Boulanger and Louis Saguer respectively, now archived in the National Library of France, along with extracts from his unedited autobiography recorded in the 1980's, and an interview he gave in the 1970’s – these last two being under the custody of Santoro's family.

The main purpose of this empirical study is to investigate the extent in which how the biographical profiles (age, gender, marital status, education levels, occupation (males and females, children and tenure can influence vulnerability and disasters in these informal settlements. A quantitative research design was adopted and a survey method was used, whereby questionnaires were administered by the researcher to a population of 240, whereby, 140 questionnaires were completed generating a response rate of 63.6%. The findings of this study reveals that the majority of the respondents in the Foreman and Kennedy Road informal settlements are black, poverty stricken, unemployed and who are suffered economic difficulties that make them highly vulnerable to disasters. This study will act an advisory role to the decision-makers as the research findings shows that in the foreseeable future in South Africa, informal settlements will be an intergral feature of formal housing, which requires urban planners to include such settlements to housing planning.

The experience and meaning of tooth loss and replacement has varied historically and culturally but has received relatively little attention from social scientists. Our study set out to understand these experiences in the context of the arrival of newer, dental implant treatments. Semi-structured qualitative interviews were carried out with 39 men and women who had experienced tooth loss and replacement. A thematic analysis was sensitised by previous sociological work on chronic illness, particularly Bury's notion of biographical disruption. We found that while for some individuals the loss of a tooth was relatively insignificant, for others it was devastating and disruptive. In seeking to understand this difference, the concept of biographical disruption was a helpful analytical tool. Our analysis identified two forms of disruption. The first related to the meanings of tooth loss (the neglected mouth) and denture wearing (a marker of old age). The second, embodied, disruption concerned the relationship between the self and mouth in those wearing dentures (the invaded, unreliable mouth) and could occur even where tooth loss and denture wearing had been biographically anticipated. © 2013 The Authors.

Building on Michael Bury's "biographical disruption" and Kathy Charmaz's "loss of self," which describe the deteriorative impacts of chronic illness on perceptions of selfhood, I propose "biographical illumination"-a transformed conceptualization of self and identity that is facilitated by but extends beyond medical meaning, enriching personal biography and social relationships. The concept is perhaps most applicable to experiences with neurological and neurodevelopmental conditions in which brain difference and personhood are perceived to be closely intertwined. In this study, biographical illumination is used to describe the experiences of autistic adults who learned of their Autism Spectrum Disorder (ASD) diagnosis during teen years or adulthood. Through an ASD lens, participants found explanation for their atypicality and developed a more valued self-concept. Learning of the condition did not disrupt their biography; rather, it became integral to and constitutive of it. With a new self-concept, participants re-gauged personal expectations for normalization and accessed communities of alike others, forging relationships that affirmed identity.

People with aphasia experience a pronounced decrease in quality of life (QoL). Beyond that identity negotiation is hindered, which is crucial for QoL. Biographic-narrative approaches use life story telling to support identity (re)development after disruptive events like stroke. Because of the language deficits inherent in aphasia such 'talk-based' approaches have to be modified for an optimal use. To evaluate an adapted interdisciplinary biographic-narrative intervention using quantitative measures of health-related quality of life (HRQL) and mood. Additionally, semi-structured interviews were conducted to gain a deeper understanding of identity development processes in people with aphasia. Twenty-seven participants with various types of chronic aphasia were enrolled. The biographic narrative intervention consisted of five face-to-face in-depth interviews and seven group sessions conducted over 10 weeks in a mixed-method design with pre- and post-tests and a follow-up assessment 3 months post-intervention. For quantitative evaluation the Aachen Life Quality Inventory (ALQI), the Satisfaction with Life Scale (SWLS) and the Visual Analog Mood Scales (VAMS) were used. Semi-structured interviews were conducted post-treatment, including questions concerning the participants' experiences with the intervention and identity change. Results were analysed using interpretative principles from Grounded Theory. For all 27 participants, we found significant and stable growth in HRQL. Self-reported states of mood also improved. As expected, overall cognitively based life satisfaction did not change. The interviews revealed two main categories: 'evaluation of the face-to-face interviews' and 'evaluation of the group sessions'. Further analysis found four overlapping main themes which were identified as identity issues: agency, control, disease concept and doing things. Our quantitative and qualitative results demonstrated the benefits associated with the biographic

Full Text Available In September 1928 Anton Webern wrote to publisher Emil Hertzka to report on the composition of a work “in the spirit of some of Bach’s Brandenburg Concertos.” In June 1934 that work stood completed as the Concerto for Nine Instruments, Op. 24. While Op. 24 has been celebrated as a paradigmatic example of Webern’s forward-looking serial techniques, it simultaneously exhibits a strong neoclassical influence, as Kathryn Bailey (1991 has demonstrated in her study of sonata and ritornello principles in the Concerto’s first movement. Neoclassical models may have also played a role in dramatically shifting conceptions of instrumentation and genre evident in sketches from the work’s extended period of composition, during which time it transformed from a piece for large symphonic orchestra, to a concerto for solo piano with orchestral accompaniment, to a concerto grosso with a continuo-like piano part. The dramatic shifts found in the sketches are best understood in relation to Webern’s compositional activities in the decade preceding Op. 24. During this period, Webern revised several of his pre-World War I orchestral compositions, reducing the size and diversity of the ensembles with an eye towards Fasslichkeit (“comprehensibility”; a similar goal motivated the arrangements he produced for Arnold Schoenberg’s Society for Private Musical Performances. When considered alongside an instrumentation-centric view of the sketches for Op. 24, these activities suggest an intriguing view of the Concerto. If its twelve-tone row marks Op. 24 as an apex of Webern’s serial technique, its instrumentation makes it an apex of his neoclassicism.In September 1928 Anton Webern wrote to publisher Emil Hertzka to report on the composition of a work “in the spirit of some of Bach’s Brandenburg Concertos.” In June 1934 that work stood completed as the Concerto for Nine Instruments, Op. 24.

As astronomy teaching faculty are changing their teaching strategies from those less desirable approaches that allow students to passively listen to professor-centered, information-lectures to more desirable, active-student engagement classrooms characterized by active learning, ASTRO 101 professors are looking for more ways to help students learn to participate in authentic scientific practices. This is consistent with notion advocated by the NRC that students should practice scientific thinking, scientific discourse, and scientific practices while learning science. Noticing that much informal scientific discussion is mediated by sketches—such as those occasionally lively discussions held after hours during scientific conferences—scholars at the CAPER Center for Astronomy & Physics Education Research have been piloting a series of active learning tasks where students are challenged to create scientific drawings to illustrate their understanding of astronomical phenomena or structures. Known informally as ScienceSKETCHES, examples of these tasks challenge students to illustrate: the spectral curve differences between high and low mass stars; the differences among galaxy shapes; the distribution of stars for the Andromeda Galaxy in terms of luminosity versus temperature; old and young planetary surfaces; or the relationships between distances and speeds of orbiting objects. Although our initial testing has focused on predominately on paper and pencil tasks, with the occasional cell phone picture of a ScienceSKETCH being texted to the professor, the electronic-based teaching world is nearly ready to support these sorts of drawing tasks. Already, the ability to complete and submit scientific sketches is becoming commonplace across electronic learning platforms, including shared white-boarding in many desktop videoconferencing systems, and handheld device learning systems for interactive classrooms, like those from Learning Catalytics, among many others.

A nursing career can last for more than 40 years, during which continuing professional development is essential. Nurses participate in a variety of learning activities that correspond with their developmental motives. Lifespan psychology shows that work-related motives change with age, leading to the expectation that motives for continuing professional development also change. Nevertheless, little is known about nurses' continuing professional development strategies in different age groups. To explore continuing professional development strategies among younger, middle-aged, and older nurses. A qualitative study using semi-structured interviews, from a biographical perspective. Data were analysed using a vertical process aimed at creating individual learning biographies, and a horizontal process directed at discovering differences and similarities between age groups. Twenty-one nurses in three age groups from general and academic hospitals in the Netherlands. In all age groups, daily work was an important trigger for professional development on the ward. Performing extra or new tasks appeared to be an additional trigger for undertaking learning activities external to the ward. Learning experiences in nurses' private lives also contributed to their continuing professional development. Besides these similarities, the data revealed differences in career stages and private lives, which appeared to be related to differences in continuing professional development strategy; 'gaining experience and building a career' held particularly true among younger nurses, 'work-life balance' and 'keeping work interesting and varied' to middle-aged nurses, and 'consistency at work' to older nurses. Professional development strategies can aim at performing daily patient care, extra tasks and other roles. Age differences in these strategies appear to relate to tenure, perspectives on the future, and situations at home. These insights could help hospitals to orientate continuing

Full Text Available We present a new structural method of sketched symbol recognition, which aims to recognize a hand-drawn symbol before it is fully completed. It is invariant to scale, stroke number, and order. We also present two novel descriptors to represent the spatial distribution between two primitives. One is invariant to rotation and the other is not. Then a symbol is represented as a set of descriptors. The distance between the input symbol and the template one is calculated based on the assignment problem. Moreover, a fast nearest neighbor (NN search algorithm is proposed for recognition. The method achieves a satisfactory recognition rate in real time.

We argue this can be seen as a balance between different levels of socio-technical complexity – ranging from micro perspectives...
Full Text Available Knowledge dissemination is an emerging issue in population studies, both in terms of ethics and data quality. The challenge is especially important in long term follow-up surveys and it requires methodological imagination when the population is illiterate. The paper presents the dissemination project developed in a demographic surveillance system implemented in rural Mali over the last 20 years. After basic experience of document transfer, the feedback strategy was developed through audiovisual shows and theatre sketches. The advantages and drawbacks of these media are discussed, in terms of scientific communication and the construction of dialogue with the target population.
The paper attempts to sketch out four distinct epistemological positions toward the player, who is understood as derived from play and game. To map out the problem field, two equally challenged positions toward computer game play are observed, emerging from inadequate treatment of the differences...... of playing a game is seen as independent of what goes on in the player’s mind (actually, the player might not even be the true subject of the game). Similar polarities are postulated regarding a game; from an exclusive viewpoint .game. is a signifying shorthand for objects, which, when observed from...

Aim: the new PET/CT biograph sensation 16 (BS16) tomographs have faster detector electronics which allow a reduced timing coincidence window and an increased lower energy threshold (from 350 to 400 keV). This paper evaluates the performance of the BS16 PET scanner before and after the Pico-3D electronics upgrade. Methods: four NEMA NU 2-2001 protocols, (i) spatial resolution, (ii) scatter fraction, count losses and random measurement, (iii) sensitivity, and (iv) image quality, have been performed. Results: a considerable change in both PET count-rate performance and image quality is observed after electronics upgrade. The new scatter fraction obtained using Pico-3D electronics showed a 14% decrease compared to that obtained with the previous electronics. At the typical patient background activity (5.3 kBq/ml), the new scatter fraction was approximately 0.42. The noise equivalent count-rate (R NEC ) performance was also improved. The value at which the R NEC curve peaked, increased from 3.7 . 10 4 s -1 at 14 kBq/ml to 6.4 . 10 4 s -1 at 21 kBq/ml (2R-NEC rate). Likewise, the peak true count-rate value increased from 1.9 . 10 5 s -1 at 22 kBq/ml to 3.4 . 10 5 s -1 at 33 kBq/ml. An average increase of 45% in contrast was observed for hot spheres when using AW-OSEM (4ix8s) as the reconstruction algorithm. For cold spheres, the average increase was 12%. Conclusion: the performance of the PET scanners in the BS16 tomographs is improved by the optimization of the signal processing. The narrower energy and timing coincidence windows lead to a considerable increase of signal-to-noise ratio. The existing combination of fast detectors and adapted electronics in the BS16 tomographs allow imaging protocols with reduced acquisition time, providing higher patient throughput. (orig.)

Geant4 application for tomographic emission (GATE) is a generic Monte Carlo simulation platform based on a general-purpose code GEANT4 and designed to simulate positron emission tomography (PET) and single photon emission tomography systems. Monte Carlo simulations are used in nuclear medicine to model imaging systems and develop and assess tomographic reconstruction algorithms and correction methods for improved image quantification. The purpose of this study is to validate two GATE models of the commercial available PET scanner HR+ and the PET/CT Biograph 2. The geometry of the system components has been described in GATE, including detector ring, crystal blocks, PMTs etc. The energy and spatial resolution of the scanners as given by the manufacturers have been taken into account. The GATE simulated results are compared directly to experimental data obtained using a number of NEMA NU-2-2001 performance protocols, including spatial resolution, sensitivity and scatter fraction. All the respective phantoms are precisely modeled. Furthermore, an approximate dead-time model both at the level of single and coincidence events was developed so that the simulated count rate curve can satisfactorily match the experimental count rate performance curve for each scanner In addition a software tool was developed to build the sinograms from the simulated data and import them into the software for tomographic image reconstruction where the reconstruction algorithm of FBP3DRP was applied. An agreement of less than 0.8 mm was obtained between the spatial resolution of the simulated system and the experimental results. Also the simulated scatter fraction for the NEMA NU 2-2001 scatter phantom matched the experimental results to within 3% of measured values. Finally the ratio of the simulated sensitivities with sources radially offset 0 and 10 cm from the central axis of each of the two scanners reaches an agreement of less than 1% between the simulated and experimental values.

Full Text Available Recently, inspired by the power of deep learning, convolution neural networks can produce fantastic images at the pixel level. However, a significant limiting factor for previous approaches is that they focus on some simple datasets such as faces and bedrooms. In this paper, we propose a multiscale deep neural network to transform sketches into Chinese paintings. To synthesize more realistic imagery, we train the generative network by using both L1 loss and adversarial loss. Additionally, users can control the process of the synthesis since the generative network is feed-forward. This network can also be treated as neural style transfer by adding an edge detector. Furthermore, additional experiments on image colorization and image super-resolution demonstrate the universality of our proposed approach.

The reconstruction of 3D objects from 2D line drawings is regarded as one of the key topics in the field of computer vision. The ongoing research is mainly focusing on the reconstruction of 3D objects that are mapped only from 2D straight lines, and that are symmetric in nature. Commonly, this approach only produces basic and simple shapes that are mostly flat or rather polygonized in nature, which is normally attributed to inability to handle curves. To overcome the above-mentioned limitations, a technique capable of handling non-symmetric drawings that encompass curves is considered. This paper discusses a novel technique that can be used to reconstruct 3D objects containing curved lines. In addition, it highlights an application that has been developed in accordance with the suggested technique that can convert a freehand sketch to a 3D shape using a mobile phone.

Full Text Available The paper A Dane writes about Chopin. Peer Hultberg’s “Preludes” as an example of a contemporary Danish biographical novel concerns the condition of a contemporary Danish biographical novel. The main focus is put on Peer Hultberg’s work Preludes on the famous Polish composer, Fryderyk Chopin. The author of the paper uses the definition of a biographical novel as Maria Jasinska understands it, and the definition of a modernist literary novel by Stephen J. Walton. The article also addresses other contemporary biographical novels written in Scandinavia. Its main aim is to examine in what respects Hultberg’s novel deviates from the standards of a modernist biographical novel. The research is based on four criteria: focus put on one character, chronological structure of the narration, including all life stages, presence of the milestones in the protagonist’s professional career and appearance of authentic characters in the novel’s plot. As it turns out, Preludes hardly fulfills any of the above-mentioned requirements. Although the protagonist is clearly defined, the polyphonic structure of the narration makes it difficult to focus on one character only. The chronological composition is present, but the plot does not include any of the milestones in the composer’s career, since the novel only concerns his childhood. As to authentic characters, they play a peripheral role in the novel’s plot. One can therefore assume that Peer Hultberg’s Preludes is a postmodernist biographical novel, where a fragment replaces the whole, and one stage of life, namely childhood, is capable of telling a story of the origin of genius.
Full Text Available Sketch-based interfaces provide a powerful, natural and intuitive way for users to interact with an application. By combining a sketch-based interface with a physically simulated environment, an application offers the means for users to rapidly sketch a set of objects, like if they are doing it on piece of paper, and see how these objects behave in a simulation. In this paper we present SketchyDynamics, a library that intends to facilitate the creation of applications by rapidly providing them a sketch-based interface and physics simulation capabilities. SketchyDynamics was designed to be versatile and customizable but also simple. In fact, a simple application where the user draws objects and they are immediately simulated, colliding with each other and reacting to the specified physical forces, can be created with only 3 lines of code. In order to validate SketchyDynamics design choices, we also present some details of the usability evaluation that was conducted with a proof-of-concept prototype

Few studies on individuals with Down syndrome (DS) have explored how they learn space. The present study examines space learning from verbal descriptions in individuals with DS, and explores the role of external cues (such as a sketch map). Twenty-eight individuals with DS and 28 matched typically-developing (TD) children listened to route or survey descriptions with or without seeing a corresponding sketch map (Description+Sketch Map [D+SM] and Description alone [D], respectively). After hearing each description, they performed tasks that involved recognizing, arranging sequentially, and locating landmarks. The results showed that individuals with DS performed less well in recognizing landmarks and arranging them sequentially. The D+SM condition produced general benefits in both groups' accuracy, though the improvement in locating landmarks was greater in the TD than in the DS group. In both groups, the D+SM condition prompted a better performance than the D condition when participants arranged landmarks sequentially after hearing a description from a route perspective, but not from a survey perspective. Overall, our results show that individuals with DS benefited when a spatial description was associated with a corresponding sketch map, albeit to a lesser degree than TD children. The findings are discussed in the light of the literature on DS and on spatial cognition in the TD domain. Copyright © 2017 Elsevier Ltd. All rights reserved.

To explore traumatic brain injury (TBI) as a biographical disruption and to study the reconstruction of everyday occupations and work participation among individuals with mild TBI. Seven focus groups were conducted with 12 women and 8 men (22-60 years) who had sustained mild TBI and participated in a return-to-work program. Interviews were analyzed using qualitative content analysis. Four interrelated themes emerged: disruption of occupational capacity and balance; changes in self-perceptions; experience of time; and occupational adjustment and reconstruction. The meaning of the impairments lies in their impact on the individual's everyday occupations. The abandonment of meaningful daily occupations and the feeling of not recognizing oneself were experienced as threats to the sense of self. Successful integration of the past, present and future was paramount to continuing life activities. The unpredictability of the future seemed to permeate the entire process of adjustment and reconstruction of daily life. Our findings show that the concept of time is important in understanding and supporting the reconstruction of daily life after TBI. The fundamental work of rehabilitation is to ameliorate the disruptions caused by the injury, restoring a sense of personal narrative and supporting the ability to move forward with life. Implications for Rehabilitation Individuals with a protracted recovery after a mild traumatic brain injury must reconstruct a new way of being and acting in the world to achieve biographical continuity. The perceived anxiety regarding changes in self and occupational identity, as well as loss of control over the future, can be attenuated through informational sessions during the hospital stay and at follow-up visits. The significant personal costs of returning to full-time employment too early indicate the need for early and ongoing vocational support in achieving a successful return to work.

When examining complex problems, such as the folding of proteins, coarse grained descriptions of the system drive our investigation and help us to rationalize the results. Oftentimes collective variables (CVs), derived through some chemical intuition about the process of interest, serve this purpose. Because finding these CVs is the most difficult part of any investigation, we recently developed a dimensionality reduction algorithm, sketch-map, that can be used to build a low-dimensional map of a phase space of high-dimensionality. In this paper we discuss how these machine-generated CVs can be used to accelerate the exploration of phase space and to reconstruct free-energy landscapes. To do so, we develop a formalism in which high-dimensional configurations are no longer represented by low-dimensional position vectors. Instead, for each configuration we calculate a probability distribution, which has a domain that encompasses the entirety of the low-dimensional space. To construct a biasing potential, we exploit an analogy with metadynamics and use the trajectory to adaptively construct a repulsive, history-dependent bias from the distributions that correspond to the previously visited configurations. This potential forces the system to explore more of phase space by making it desirable to adopt configurations whose distributions do not overlap with the bias. We apply this algorithm to a small model protein and succeed in reproducing the free-energy surface that we obtain from a parallel tempering calculation. PMID:22427357

Full Text Available Archaeological research provides the widest opportunity for researchers to analyse various aspects and disciplines appropriate to the subject and the object of choice. Subject and object selection is the work of exploration artefacts found in particular sites and archaeological heritage. Exploration and excavation on of a world heritage site such as Lenggong enables researchers to uncover various archaeological artefacts that are rich and meaningful. To find evidence of the strength and benefits of an artefact, further studies on each artefact should be carried out continuously. This essay will track the wisdom of the ancient artists use to produce paintings in a limestone cave in Lenggong, Perak, using spray techniques. Some artefacts that are identified as cave paintings show a very interesting sketch technique that are unique and special. This essay will also examine some of the cave paintings in other caves in Perak and also other caves in several countries as comparison. Studies involving cave paintings in Malaysia are new compared to Western countries. Thus, the study of one of the technique which is spray technique can open the eyes of the audience to acknowledge and recognise the ancient heritage. It also hoped that this study is able to increase the body of knowledge that goes beyond the boundaries of the arts district and the country.
Full Text Available This paper presents a functional design sketch for the resource management module of a highly scalable collaborative system. Small and medium enterprises require such tools in order to benefit from and develop innovative business ideas and technologies. As computing power is a modern increasing demand and no easy and cheap solutions are defined, especially small companies or emerging business projects abide a more accessible alternative. Our work targets to settle a model for how P2P architecture can be used as infrastructure for a collaborative system that delivers resource access services. We are focused on finding a workable collaborative strategy between peers so that the system offers a cheap, trustable and quality service. Thus, in this phase we are not concerned about solutions for a specific type of task to be executed by peers, but only considering CPU power as resource. This work concerns the resource management module as a part of a larger project in which we aim to build a collaborative system for businesses with important resource demands

Full Text Available This paper examines the way authors of three medieval Islamic biographical dictionaries portrayed the lives, behavior and characteristics of three key figures of Greco-Roman medicine, Asclepius, Hippocrates and Galen. Particular attention was given to the vocabulary and phrasing used in the biographies, and associations with other literary genres or figures. An analysis of these biographies demonstrates a significant resemblance between the portrayal of these Greco-Roman physicians and the lives of prophetic figures in Islam, and especially that of the Prophet Muḥammad. In addition, these biographies align with features attributed to pious Muslims. This study demonstrates that Muslim biographers constructed these biographies as part of a general tendency to associate medicine with Islam, and the origins of medical knowledge with prophetic wisdom. This study mantains that the connotations and use of this particular terminology allows for a positive view of the science of medicine in these Islamic compositions in which they were included.Este artículo analiza la manera en que los autores de tres diccionarios biográficos islámicos medievales retrataron la vida y características de las tres figuras más destacadas de la medicina greco-romana: Asclepio, Hipócrates y Galeno.

The Biographical Personality Interview (BPI) is a research instrument for the retrospective assessment of premorbid personality traits of psychiatric patients. Its construction is based on results of a series of investigations in which biographical data from psychiatric case notes were analysed with respect to premorbid personality traits. In order to avoid methodological shortcomings of the utilisation of clinical records, an interview technique was developed. It is applied by two independent, specially trained investigators who are kept "blind" regarding any clinical data of the subject under study. One of them has to conduct the interview of a clinically remitted patient and to provide an interview protocol, the other one has to rate personality traits from that protocol along a large series of purely descriptive items. Sum scores for six personality structures ("types") are calculated and the case is then assigned to the intra-individually dominating personality type according to the highest of these scores.

Intimate partner violence (IPV) is a serious social issue which affects the medium- and long-term health outcomes of many individuals worldwide. The cost of IPV on the physical and psychological well-being of individuals, in addition to its wider economic costs in responding to abused persons, is significant. Presently, there is a lack of understanding about the nature of female-initiated IPV and how men account for their experiences of it. This study examined male victims' life stories of their IPV experiences from their intimate partners. Using the biographical narrative interpretive method, three cases were analyzed from a social constructionist perspective to examine what narrative strategies men used to account for their experiences of being abused by their female partners. Three dominant narrative strategies were used by respondents: the fatherhood narrative, the good husband narrative, and the abuse narrative. The abuse narrative had a unique narrative form, which reflected respondents' disassociation between their identities as men and also as abused persons. Dominant conflicting discourses of masculinity and intimate partner abuse disadvantaged men in identifying IPV and secondly in responding appropriately. This study found that men prefer to use dominant discursive identities as legitimate means from which to disclose IPV experiences. The findings from this study illustrate that broad questioning by professionals regarding fatherhood may be most helpful in promoting disclosures of IPV if this is suspected. © The Author(s) 2014.

The model integrates two seemingly irreconcilable research traditions: The addiction/disease model in medical-psychological research investigates dysfunctionality of gaming in pathological gamers. Game studies focus on functionality of in-game behavior and establish gamer typologies based on gaming motives. By adding the biographical context to game studies, but keeping the gamer's perspective, we show that gamers whose lives become dominated by gaming may know what they want and "virtually" get it, but still not "really" get it in the long term. "Compensatory" gaming does not, thus, equal unproblematic or "non-addicted" gaming. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs150387
The article is an attempt of a new outlook first of all upon scientific output of many years' (the years 1878 - 1909) lecturer on Russian State Law in the Imperial University of Warsaw--Aleksandr Lwowicz Błok. Historians of literature, researchers of life and output of the scientist's son, an eminent poet-symbolist Aleksandr A. Błok, to a high degree were able to reconstruct lot of life and vicissitudes of the Warsaw professor. Thanks to the preserved university archival materials it was possible to add many details to Błok's biography, especially concerning his professional problems. They were connected with dramatic events in personal life of the professor. According to relations of the part of his university co-workers and students, the circumstances even brought about the symptoms of the mental illness. Prematurely elderly he was a man deeply miserable, lonely and deprived of understanding by associates. Up till now his scientific output has not been described precisely enough. Not numerous memories of his contemporaries (Szymon Askenazy, Nikołaj Dubrowskij) and even inconspicuous modern researches of the Polish (Janusz Woliński) brought about, in the author's opinion, too simplified and schematic character-sketch of Błok as a Russificator and nationalist, mediocre scholar and much worse lecturer. A scientific output of Błok is, indeed, inostensible--he published 2 books only--Master's thesis entitled: Władza państwowa w społeczeństwie europejskim. Poglad na polityczna teorie Lorenza Steina i na francuska rzeczywistość polityczna (1880) [State Authority in European Society.

Two sunspot observations recorded by the Mexican Felipe de Zúñiga y Ontiveros have been revealed from a manuscript. One sunspot group was recorded on 9th January 1777 and four sunspot groups on 29th December 1777. Both records were taken during the observation of solar eclipses from Mexico City and their description also included sketches of the solar disk with sunspots. The sunspot group corresponding to 9th January was also observed by Erasmus Lievog. The observation on 29th December 1777 is the only record corresponding to this date.

The pin power reconstruction model was incorporated in the 3-D nodal kinetics code SKETCH-INS in order to produce accurate calculation of three-dimensional pin power distributions throughout the reactor core. In order to verify the employed pin power reconstruction model, the PWR MOX/UO_2 core transient benchmark problem was analyzed with the coupled code system SKETCH-INS/TRACE by incorporating the model and the influence of pin power reconstruction model was studied. SKETCH-INS pin power distributions for 3 benchmark problems were compared with the PARCS solutions which were provided by the host organisation of the benchmark. SKETCH-INS results were in good agreement with the PARCS results. The capability of employed pin power reconstruction model was confirmed through the analysis of benchmark problems. A PWR control rod ejection benchmark problem was analyzed with the coupled code system SKETCH-INS/ TRACE by incorporating the pin power reconstruction model. The influence of pin power reconstruction model was studied by comparing with the result of conventional node averaged flux model. The results indicate that the pin power reconstruction model has significant effect on the pin powers during transient and hence on the fuel enthalpy

Full Text Available This paper presents the results of a preliminary protocol study of the cognitive behaviour of architectural designers during the design process. The aim is to better understand the similarities and differences in cognitive behaviour using Sequential Mixed Media (SMM and Alternative Mixed Media (AMM approaches, and how switching between media may impact on design processes. Two participants with at least one-year’s professional design experience and a Bachelor of Design degree, and competence in both sketching and computer-aid design (CAD modelling participated in the study. Video recordings of participants working on different projects were coded using the Function-Behaviour-Structure (FBS coding scheme. Participants were also interviewed and their explanations about their switching behaviours were categorised into three types: S→C, S/C↹R and C→S. Preliminary results indicate that switching between media may influence how designers identify problems and develop solutions. In particular, two design issues were identified. These relate to the FBS coding scheme, where structure (S and behaviour derived from structure (Bs, change to documentation (D after switching from sketching to CAD modelling (S→C. These switches make it possible for designers to integrate both approaches into one design medium and facilitate their design processes in AMM design environments.

While growing up in Cedar Rapids, Iowa, Milton Wright, The Wright Brothers Father, liked to purchase toys for his sons that he hoped would stimulate their imagination. One of the most memorable gifts was a toy helicopter that was designed by the French aeronautical experimenter Alphonse P naud. Milton gave his sons this gift in 1878, and, though it was a simple device with a stick bound to a four-blade rotor set in a spindle, it had the intended effect it caused them to dream. Twenty-five years separated the gift of this toy and their invention of the airplane, yet the Wright brothers were convinced it had exerted an important influence. Tom Crouch argued in The Bishop's Boys that toys like these perfectly illustrated the significance of play for technological innovation. He wrote, rotary-wing toys were to intrigue and inspire generations of children, a few of whom would, as adults, attempt to realize the dream of flight for themselves. If the first powered flight on 17 December 1903 represented a childhood dream realized, it was only the first step in the rapid evolution of the airplane from their flimsy kite-like contraption of wood and cloth to jet airliners and rockets in space. And, as extraordinary as the achievement of powered flight seemed in 1903, before the end of the century, space travel also would become a dream realized. Soviet astronaut Yuri Gagarin first circumnavigated Earth in April 1961, and, eight years later, American astronauts took the first steps for humankind on the Moon. It is with great pleasure that we introduce Realizing the Dream: Biographical Essays in Honor of the Centennial of Flight. These essays in celebration of the Wright brothers first flight 100 years ago grew out of presentations by a group of prominent scholars in 2003 at a conference sponsored by the NASA History Division and held at the Great Lakes Science Center in Cleveland, Ohio. The volume focuses on the careers of some of the many men and women who helped to realize

The Siemens Biograph TruePoint TrueV (B-TPTV) positron emission tomography (PET) scanner performs 3D PET reconstruction using a system matrix with point spread function (PSF) modeling (called the True X reconstruction). PET resolution was dramatically improved with the True X method. In this study, we assessed the spatial resolution and image quality on a B-TPTV PET scanner. In addition, we assessed the feasibility of animal imaging with a B-TPTV PET and compared it with a microPET R4 scanner. Spatial resolution was measured at center and at 8 cm offset from the center in transverse plane with warm background activity. True X, ordered subset expectation maximization (OSEM) without PSF modeling, and filtered back-projection (FBP) reconstruction methods were used. Percent contrast (% contrast) and percent background variability (% BV) were assessed according to NEMA NU2-2007. The recovery coefficient (RC), non-uniformity, spill-over ratio (SOR), and PET imaging of the Micro Deluxe Phantom were assessed to compare image quality of B-TPTV PET with that of the microPET R4. When True X reconstruction was used, spatial resolution was RC with True X reconstruction was higher than that with the FBP method and the OSEM without PSF modeling method on the microPET R4. The non-uniformity with True X reconstruction was higher than that with FBP and OSEM without PSF modeling on microPET R4. SOR with True X reconstruction was better than that with FBP or OSEM without PSF modeling on the microPET R4. This study assessed the performance of the True X reconstruction. Spatial resolution with True X reconstruction was improved by 45 % and its % contrast was significantly improved compared to those with the conventional OSEM without PSF modeling reconstruction algorithm. The noise level was higher than that with the other reconstruction algorithm. Therefore, True X reconstruction should be used with caution when quantifying PET data.

Edward Teller died on September 9, 2003 in Stanford, California at the age of 95. He was both one of the great theoretical physicists of the twentieth century and a leading figure in the development of nuclear weapons and broader defense advocacy. Teller's work in physics, spanning many decades of the twentieth century, includes some of the most fundamental insights in the quantum behaviors of molecules and their spectra, nuclei, surfaces, solid state and spin systems, and plasmas. In the defense arena, Teller is best known for his key insight that made thermonuclear weapons possible. Teller was both a great scientific collaborator and physics teacher at all levels, known for his openness, generosity, personal warmth, and powerful physical intuition. Many of his graduate students went on to illustrious careers.

Abstract Microbes are the oldest and most widespread, phylogenetically and metabolically diverse life forms on Earth. However, they have been discovered only 334 years ago, and their diversity started to become seriously investigated even later. For these reasons, microbial studies that unveil novel microbial lineages and processes affecting or involving microbes deeply (and repeatedly) transform knowledge in biology. Considering the quantitative prevalence of taxonomically and functionally unassigned sequences in environmental genomics data sets, and that of uncultured microbes on the planet, we propose that unraveling the microbial dark matter should be identified as a central priority for biologists. Based on former empirical findings of microbial studies, we sketch a logic of discovery with the potential to further highlight the microbial unknowns. PMID:29420719
A general approach to the reduction of the equations of systems composed of many subsystems of equations for, in general, few order parameters at instability points is sketched. As special case generalized Ginzburg-Landau equations are obtained. Recent results based on these equations, showing pattern formation in the convection instability and flames, are presented. Bifurcations from tori to other tori are treated, and some general conclusions are drawn. Analogies between fluid dynamics and lasers which led to the prediction of laser light chaos by Haken (1975) are pointed out. Finally the suspension of a class of discrete one-dimensional maps is discussed and explicitly presented for a typical case. 21 references.

Worldwide discrepancies in the classification, terminology and diagnosis of mental disorders have induced efforts for unification after World War II. This led to the introduction of an operational diagnostic approach according to strict criteria, at the same time taking into account the comorbidity of disorders. However, this approach is still not routinely used. The consequences of this deficiency are demonstrated here by an example from biographical research referring to the Bavarian King Ludwig II. The study is based on an extensive search of the relevant literature. Although the pathography of this Bavarian king is well documented, the diagnoses published between 1910 and 2010 by altogether 21 specialists, are distributed rather chaotically over 24 diagnostic categories of the ICD-10. Merely in the (probably wrong) diagnosis of a schizophrenic psychosis is there agreement among half of the authors. This is concordant with the expert diagnosis of paranoia by von Gudden and his colleagues (1886) when considering the then contemporary concept of the disorder. According to modern diagnostic principles almost half of the 24 diagnoses can be confirmed. The others have to be regarded as false diagnoses. The conclusion is that modern principles of the diagnosis of mental disorders should be applied according to internationally accepted diagnostic manuals. This approach should be used in, but is not exclusive to, biographical research. Precondition is, of course, the exact knowledge and careful application of these principles.

The Best Estimate Plus Uncertainty (BEPU) method has been prepared for the regulatory cross-check analysis at Japan Nuclear Energy Safety Organization (JNES) on base of the three-dimensional neutron-kinetics/thermal-hydraulics coupled code SKETCH-INS/TRACE5.0. In the preparation, TRACE5.0 is verified against the large-scale thermal-hydraulic tests carried out with NUPEC facility. These tests were focused on the pressure drop of steam-liquid two phase flow and void fraction distribution. From the comparison of the experimental data with other codes (RELAP5/MOD3.3 and TRAC-BF1), TRACE5.0 was judged better than other codes. It was confirmed that TRACE5.0 has high reliability for thermal hydraulics behavior and are used as a best-estimate code for the statistical safety evaluation. Next, the coupled code SKETCH-INS/TRACE5.0 was applied to turbine trip tests performed at the Peach Bottom-2 BWR4 Plant. The turbine trip event shows the rapid power peak due to the voids collapse with the pressure increase. The analyzed peak value of core power is better simulated than the previous version SKETCH-INS/TRAC-BF1. And the statistical safety evaluation using SKETCH-INS/TRACE5.0 was applied to the loss of load transient for examining the influence of the choice of sampling method. (author)

The Biographical Personality Interview (BPI) was applied to 179 subjects (158 psychiatric patients and 21 probands from the general population); 100 patients and 20 healthy controls served as a validation sample; the others had been interviewed during the training period or did not meet the inclusion criteria for the validation of the BPI. The acceptance of the interview was high, the inter-rater reliability of the ratings of premorbid personality structures ("types") varied between 0.81 and 0.88 per type. Concurrent validity of the typological constructs as assessed by means of the BPI was inferred from the intercorrelations of type scores and correlations of these scores with questionnaire data and proved to be adequate. Clinical validity of the assessment was indicated by statistically significant differences between diagnostic groups. Problems and further developments of the instrument and its application are discussed.
Personality, biographical characteristics, and job interview success: a longitudinal study of the mediating effects of interviewing self-efficacy and the moderating effects of internal locus of causality.
Tay, Cheryl; Ang, Soon; Van Dyne, Linn
In this study, the authors developed and tested a model of performance in job interviews that examines the mediating role of interviewing self-efficacy (I-SE; job applicants' beliefs about their interviewing capabilities) in linking personality and biographical background with interview success and the moderating role of locus of causality attributions in influencing the relationship between interview success and subsequent I-SE. The authors tested their model (over 5 months' duration) with matched data from 229 graduating seniors, firms, and university records. Hierarchical regression analyses demonstrated I-SE mediated the effects of Extraversion, Conscientiousness, and leadership experience on interview success. Locus of causality attributions for interview outcomes moderated the relationship between interview success and subsequent I-SE. Theoretical and practical implications are discussed.
Full Text Available This reader contains analyses of gender constructions in East and West Germany from biographical perspectives. It is based on narrative interviews with women and men living in the former East and West. By means of case reconstructions and case comparisons the authors reveal how individuals deal actively with specific societal gender roles. Historical differences between women's movement and feminism in East Germany versus West Germany are knowledgeably described. The book offers a very complex and multilayered theoretical and empirical construction of gender in its diverse dimensions, but men's biographies and men's studies remain marginalized. Men's movements as well as the gay rights movement are blind spots. The gendering of work and the context of European unification are emphasized. URN: urn:nbn:de:0114-fqs0602353

To further examine how factors such as those identified from the Phase I NMT study, and the modeling framework developed under that effort could be applied to local/regional level planning activities, FHWA decided to pursue a Phase II study. It was determined that a small geographic area with more detailed local data would be necessary. Although Washington D.C. was not one of the 2009 NHTS add-ons, it did conduct a household travel survey of 11,000 households in 2007-2008. The National Capital Region Transportation Planning Board at the Metropolitan Washington Council of Governments (MWCOG) conducted the household travel survey. The data coverage under the MWCOG survey is much higher than that of the NHTS. As a part of the Phase II study, a prototype of a Geographic Information System (GIS)-based sketch planning visualization tool was also to be developed. The intent was to use a neighborhood in the Washington D.C. region as a case study for this prototype application.

Full Text Available It discusses the meanings given by 14 physical education teachers about their experiences with the continued formation process. It is a (auto biographical narrative research, which used focal groups and interviews as tools for compiling the data. The colaborators are six male teachers and eight female teachers of municipal networks from Serra, Vitoria and Viana municipalities in the metropolitan region of Vitória, ES. The analyzes indicate that the assigned meanings are related to the collective need to reorganize institutional provided formations in dialogue with the political interests of teachers and the specificity of Physical Education as a curriculum component. In general, teachers consider the formation focused on practice and in the teaching profession as those that best reflect their expectations. The practice appears as a know-how to be appropriate from continued formetion to be experienced in school; a knowledge that, when apprehended, is reframed to produce other experiences.

The basic Geometry skills are needed by the students to solve the geometrical tasks in daily life. There are five aspects of the Geometry ability based on the Hoffer’s theory. They are visual, verbal, drawing, logical, and application. These are the abilities that the students in junior high school level need to master. The purpose of this study is to find out and describe the effectiveness of the interactive media supported by Google SketchUp to improve the students’ basic Geometry skills based on Hoffer’s theory. The subject in this research is 30 students from class 9E in Junior High School of Mojogedang 1, Karanganyar regency. This study uses a pre-test and post-test experiment and analyzed with the t-test hypothesis with the significant level of 5%. The result of this study can be seen from the diffeence average score between the pre-test and post-test, which shows a significance difference. It means that through the interactive media supported by Google SketchUp, the students’ five basic abilities are improved. Therefore, it can be concluded that the interactive media supported by Google SketchUp is potential and can be used to help the students in improving their basic Geometry skills based on Hoffer’s theory.
Full Text Available The speed and pen-pressure while sketching a spiral are lower among Parkinson’s disease (PD patients with higher severity of the disease. However, the correlation between these features and the severity level (SL of PD has been reported to be 0.4. There is a need for identifying parameters with a stronger correlation for considering this for accurate diagnosis of the disease. This study has proposed the use of the Composite Index of Speed and Pen-pressure (CISP of sketching as a feature for analyzing the severity of PD. A total of 28 control group (CG and 27 PD patients (total 55 participants were recruited and assessed for Unified Parkinson’s Disease Rating Scale (UPDRS. They drew guided Archimedean spiral on an A3 sheet. Speed, pen-pressure, and CISP were computed and analyzed to obtain their correlation with severity of the disease. The correlation of speed, pen-pressure, and CISP with the severity of PD was −0.415, −0.584, and −0.641, respectively. Mann–Whitney U test confirmed that CISP was suitable to distinguish between PD and CG, while non-parametric k-sample Kruskal–Wallis test confirmed that it was significantly different for PD SL-1 and PD SL-3. This shows that CISP during spiral sketching may be used to differentiate between CG and PD and between PD SL-1 and PD SL-3 but not SL-2.

To understand the true force of the facts of paleobotany as arguments for geology it is essential that their full biologic significance be grasped. It has therefore been deemed proper, in this introduction to the several tabular and systematic statements which will make up the bulk of the volume and bear chiefly upon the geological aspect of the subject, to consider certain of the more important biologic questions, in addition to the specially geologic ones, and to discuss, from an historical and developmental standpoint, some of the leading problems of modern phytology.

Furthermore, the author presents unknown information and pieces that help to understand more clearly their work in terracotta, fundamental in the transition from Mannerism toward Naturalism in Andalusian sculpture.
The aim of this study was to explore the connection between the nature of agitated behaviour and meaningful biographical experiences within two types of dementia in a moderate stadium. The two dementia types included Alzheimer Disease (SDAT) and Multi-infarction aphrenia (MID). Biographical narrative interviews with 26 nursing home residents suffering from dementia have been concluded. Topics were their first thirty years of life (based on a foreign anamnesis). The challenging behaviour has been observed systematically in nursing situations. The data has been evaluated with the comparative casuistics method (Jüttemann, 1990). The behaviour has been measured with the CMAI-scale before and also after having moved to a nursing home. Residents behaviour patterns can be divided into three biographical central characters: Life as finding, life as emotional disorder and life as struggle. Institutional characteristics: Loss of near rhythms of life, losing control over the personal area, experience of social isolation and certain characteristics from nurses: staff detractions and the exercise of nursing actions which appears threats contribute to the phenomena. A disparity is shown between the types of dementia in terms of patterns of demonstrated behaviour. In addition gender differences could be shown. The recognition of the phenomena by means of the CMAI-scale elucidate that the phenomena appears for the first time or is stronger after the resettlement to a nursing home. These findings can improve nurses' understanding of the phenomena within long-term care.

Stellar Formation brings together knowledge about the formation of stars. In seeking to determine the conditions necessary for star formation, this book examines questions such as how, where, and why stars form, and at what rate and with what properties. This text also considers whether the formation of a star is an accident or an integral part of the physical properties of matter. This book consists of 13 chapters divided into two sections and begins with an overview of theories that explain star formation as well as the state of knowledge of star formation in comparison to stellar structure

Galaxy formation is at the forefront of observation and theory in cosmology. An improved understanding is essential for improving our knowledge both of the cosmological parameters, of the contents of the universe, and of our origins. In these lectures intended for graduate students, galaxy formation theory is reviewed and confronted with recent observational issues. In lecture 1, the following topics are presented: star formation considerations, including IMF, star formation efficiency and star formation rate, the origin of the galaxy luminosity function, and feedback in dwarf galaxies. In lecture 2, we describe formation of disks and massive spheroids, including the growth of supermassive black holes, negative feedback in spheroids, the AGN-star formation connection, star formation rates at high redshift and the baryon fraction in galaxies.

Effective interagency and cross-sector coordination is essential to ecosystem based management which depends on processes characterized by collaboration and science-based information. Many technological barriers that exist in the development of science-based management plans are closely tied to process challenges, such as the sharing of data and information or the inclusion of parties with varied levels of technical experience. The Channel Islands National Marine Sanctuary has convened a diverse working group to develop recommendations for the management of marine shipping in and around the Santa Barbara Channel, as well as recommendations regarding research needs and outreach strategies. Working group members take a multi-issue approach with four distinct goals related to the reduction of ship strikes on whales, emissions and air quality, conflicting ocean uses, and issues of navigational safety. Members range from industry representatives, scientists, and multiple local and federal government entities. The recommended management plans will be based in the best-available science, and will build off of previous efforts, making this an interesting case study of adaptive management. In addition to support from the Sanctuary and professional facilitators, the group is using a decision-support platform, SeaSketch (safepassage.seasketch.org). SeaSketch is a web-based GIS that supports collaborative science-based marine spatial planning (MSP). Each feature supports a step of the MSP process, from data gathering, identification of data needs, the design of spatial plans, evaluation of those plans with analytics, and map-based forums that facilitate data-driven discussions. Working group members are able to access these tools to explore management options and collaborate remotely, in addition to using the platform during in-person meetings and webinars. Empowering diverse audiences to engage in the design of science-based plans is of key importance to developing ecosystem

Full Text Available This review provides a rough sketch of the evidence, gaps and promising directions in e-learning from 2000 onwards, with a particular focus on Canada. We searched a wide range of sources and document types to ensure that we represented, comprehensively, the arguments surrounding e-learning. Overall, there were 2,042 entries in our database, of which we reviewed 1,146, including all the Canadian primary research and all scholarly reviews of the literature. In total, there were 726 documents included in our review: 235 – general public opinion; 131 – trade/practitioners’ opinion; 88 – policy documents; 120 – reviews; and 152 – primary empirical research. The Argument Catalogue codebook included the following eleven classes of variables: 1 Document Source; 2 Areas/Themes of e-learning; 3 Value/Impact; 4 Type of evidence; 5 Research design; 6 Area of applicability; 7 Pedagogical implementation factors; 8 A-priori attitudes; 9 Types of learners; 10 Context; and 11 Technology Factors. We examined the data from a number of perspectives, including their quality as evidence. In the primary research literature, we examined the kinds of research designs that were used. We found that over half of the studies conducted in Canada are qualitative in nature, while the rest are split in half between surveys and quantitative studies (correlational and experimental. When we looked at the nature of the research designs, we found that 51% are qualitative case studies and 15.8% are experimental or quasi-experimental studies. It seems that studies that can help us understand “what works” in e-learning settings are underrepresented in the Canadian research literature. The documents were coded to provide data on outcomes of e-learning (we also refer to them as “impacts” of e-learning. Outcomes/impacts are the perceived or measured benefits of e-learning, whereas predictors are the conditions or features of e-learning that can potentially affect the

Full Text Available For policy making and spatial planning, information is needed about the impacts of climate change on natural ecosystems. To provide this information, commonly hydrological and ecological models are used.

The world's languages display important differences in their rhythmic organization; most particularly, different languages seem to privilege different phonological units (mora, syllable, or stress foot) as their basic rhythmic unit. There is now considerable evidence that such differences have important consequences for crucial aspects of language acquisition and processing. Several questions remain, however, as to what exactly characterizes the rhythmic differences, how they are manifested at an auditory/acoustic level and how listeners, whether adult native speakers or young infants, process rhythmic information. In this paper it is proposed that the crucial determinant of rhythmic organization is the variability in the auditory prominence of phonetic events. In order to test this auditory prominence hypothesis, an auditory model is run on two multi-language data-sets, the first consisting of matched pairs of English and French sentences, and the second consisting of French, Italian, English and Dutch sentences. The model is based on a theory of the auditory primal sketch, and generates a primitive representation of an acoustic signal (the rhythmogram) which yields a crude segmentation of the speech signal and assigns prominence values to the obtained sequence of events. Its performance is compared with that of several recently proposed phonetic measures of vocalic and consonantal variability.

Theoretical models of star formation are discussed beginning with the earliest stages and ending in the formation of rotating, self-gravitating disks or rings. First a model of the implosion of very diffuse gas clouds is presented which relies upon a shock at the edge of a galactic spiral arm to drive the implosion. Second, models are presented for the formation of a second generation of massive stars in such a cloud once a first generation has formed. These models rely on the ionizing radiation from massive stars or on the supernova shocks produced when these stars explode. Finally, calculations of the gravitational collapse of rotating clouds are discussed with special focus on the question of whether rotating disks or rings are the result of such a collapse. 65 references

There has been vast progress in our understanding of planetesimal formation over the past decades, owing to a number of laboratory experiments as well as to refined models of dust and ice agglomeration in protoplanetary disks. Coagulation rapidly forms cm-sized ''pebbles'' by direct sticking in collisions at low velocities (Güttler et al. 2010; Zsom et al. 2010). For the further growth, two model approaches are currently being discussed: (1) Local concentration of pebbles in nebular instabilities until gravitational instability occurs (Johansen et al. 2007). (2) A competition between fragmentation and mass transfer in collisions among the dusty bodies, in which a few ''lucky winners'' make it to planetesimal sizes (Windmark et al. 2012a,b; Garaud et al. 2013). Predictions of the physical properties of the resulting bodies in both models allow a distinction of the two formation scenarios of planetesimals. In particular, the tensile strength (i.e, the inner cohesion) of the planetesimals differ widely between the two models (Skorov & Blum 2012; Blum et al. 2014). While model (1) predicts tensile strengths on the order of ˜ 1 Pa, model (2) results in rather compactified dusty bodies with tensile strengths in the kPa regime. If comets are km-sized survivors of the planetesimal-formation era, they should in principle hold the secret of their formation process. Water ice is the prime volatile responsible for the activity of comets. Thermophysical models of the heat and mass transport close to the comet-nucleus surface predict water-ice sublimation temperatures that relate to maximum sublimation pressures well below the kPa regime predicted for formation scenario (2). Model (1), however, is in agreement with the observed dust and gas activity of comets. Thus, a formation scenario for cometesimals involving gravitational instability is favored (Blum et al. 2014).

To understand the meaning of the term Systems Medicine and to distinguish it from seemingly related other expressions currently in use, such as precision, personalized, -omics, or big data medicine, its underlying history and development into present time needs to be highlighted. Having this development in mind, it becomes evident that Systems Medicine is a genuine concept as well as a novel way of tackling the manifold complexity that occurs in nowadays clinical medicine-and not just a rebranding of what has previously been done in the past. So looking back it seems clear to many in the field that Systems Medicine has its origin in an integrative method to unravel biocomplexity, namely, Systems Biology. Here scientist by now gained useful experience that is on the verge toward implementation in clinical research and practice.Systems Medicine and Systems Biology have the same underlying theoretical principle in systems-based thinking-a methodology to understand complexity that can be traced back to ancient Greece. During the last decade, however, and due to a rapid methodological development in the life sciences and computing/IT technologies, Systems Biology has evolved from a scientific concept into an independent discipline most competent to tackle key questions of biocomplexity-with the potential to transform medicine and how it will be practiced in the future. To understand this process in more detail, the following section will thus give a short summary of the foundation of systems-based thinking and the different developmental stages including systems theory, the development of modern Systems Biology, and its transition into clinical practice. These are the components to pave the way toward Systems Medicine.
Modern observational techniques are still not powerful enough to directly view planet formation, and so it is necessary to rely on theory. However, observations do give two important clues to the formation process. The first is that the most primitive form of material in interstellar space exists as a dilute gas. Some of this gas is unstable against gravitational collapse, and begins to contract. Because the angular momentum of the gas is not zero, it contracts along the spin axis, but remains extended in the plane perpendicular to that axis, so that a disk is formed. Viscous processes in the disk carry most of the mass into the center where a star eventually forms. In the process, almost as a by-product, a planetary system is formed as well. The second clue is the time required. Young stars are indeed observed to have gas disks, composed mostly of hydrogen and helium, surrounding them, and observations tell us that these disks dissipate after about 5 to 10 million years. If planets like Jupiter and Saturn, which are very rich in hydrogen and helium, are to form in such a disk, they must accrete their gas within 5 million years of the time of the formation of the disk. Any formation scenario one proposes must produce Jupiter in that time, although the terrestrial planets, which don't contain significant amounts of hydrogen and helium, could have taken longer to build. Modern estimates for the formation time of the Earth are of the order of 100 million years. To date there are two main candidate theories for producing Jupiter-like planets. The core accretion (CA) scenario supposes that any solid materials in the disk slowly coagulate into protoplanetary cores with progressively larger masses. If the core remains small enough it won't have a strong enough gravitational force to attract gas from the surrounding disk, and the result will be a terrestrial planet. If the core grows large enough (of the order of ten Earth masses), and the disk has not yet dissipated, then
The article sketches the history of naukoznawstwo (literally meaning the science connoisseurship or the science of science or science studies) in Poland from the 1910s to the end of the Cold War (1991), and the recovery of full political independence in 1993. It outlines the changing research perspectives of this interdisciplinary field of knowledge in Poland against a background of changing political conditions caused by the reconfigurations of the political order. The first part of the article concerns the period from the 1910s, when Poland was occupied by Russia, Prussia, and Austria, through the regaining of independence by Poland in 1918, the reconstruction of the state in 1918-1939; the second part--World War II; the third part--the period from the initial period of Soviet dominance (1944-1954) in Poland and simultaneously the beginnings of the Cold War (1947-1954), the period 1955-1956 (when the Polish state was liberated from Sovietization), through the different political crises in October 1956, March 1968, December 1970, and June 1976, to the emergence of the Independent Self-governing Trade Union Solidarity in September 1980, the end of the Cold War (1991), and the recovery of full political independence in 1993. The article outlines the fundamental achievements of prominent Polish scholars (among others K. Twardowski, M. Ossowska, S. Ossowski, T. Kotarbiński, K. Ajdukiewicz, S. Michalski, F. Znaniecki, B.

This second edition of Galaxy Formation is an up-to-date text on astrophysical cosmology, expounding the structure of the classical cosmological models from a contemporary viewpoint. This forms the background to a detailed study of the origin of structure and galaxies in the Universe. The derivations of many of the most important results are derived by simple physical arguments which illuminate the results of more advanced treatments. A very wide range of observational data is brought to bear upon these problems, including the most recent results from WMAP, the Hubble Space Telescope, galaxy surveys like the Sloan Digital Sky Survey and the 2dF Galaxy Redshift Survey, studies of Type 1a supernovae, and many other observations.
The current debate on the origin and evolution of galaxies is reviewed and evidence to support the so-called 'isothermal' and 'adiabatic' fluctuation models considered. It is shown that new theories have to explain the formation of both spiral and elliptical galaxies and the reason for their differences. It is stated that of the most recent models the best indicates that rotating spiral galaxies are formed naturally when gas concentrates in the centre of a great halo and forms stars while ellipticals are explained by later interactions between spiral galaxies and merging, which can cancel out the rotation while producing an elliptical galaxy in which the stars, coming from two original galaxies, follow very elliptical, anisotropic orbits.

Habits, both good ones and bad ones, are pervasive in animal behavior. Important frameworks have been developed to understand habits through psychological and neurobiological studies. This work has given us a rich understanding of brain networks that promote habits, and has also helped us to understand what constitutes a habitual behavior as opposed to a behavior that is more flexible and prospective. Mounting evidence from studies using neural recording methods suggests that habit formation is not a simple process. We review this evidence and take the position that habits could be sculpted from multiple dissociable changes in neural activity. These changes occur across multiple brain regions and even within single brain regions. This strategy of classifying components of a habit based on different brain signals provides a potentially useful new way to conceive of disorders that involve overly fixed behaviors as arising from different potential dysfunctions within the brain's habit network.

It was published in 1943, and in our opinion it was the first serious article on thermal biology of reptiles, which should consider the beginning of the researches in this scientific field. In 1940-s Serafima S.Lieberman and Nina V.Pokrovskaya were the students of the biological faculty of Moscow state University and worked in the Department of vertebrate zoology. Together with the whole country, they bravely endured the difficulties of the great Patriotic war and, as best they could, contributed to the victory. Their scientific supervisors were the remarkable biologists who worked at the same Department: A. M. Sergeev, Prof. A. N. Formozov and Prof. B. S. Matveev, and that perhaps helped their work to become so important. Later, however, they did not link their activities with Herpetology and worked in other fields of biology. Sima Lieberman and Nina Pokrovskaya were warm friends all their lives. Their children and grandchildren maintain good relations up today.
Full Text Available Tendaguru is one of the most important dinosaur localities in Africa. The Tendaguru Beds have produced a diverse Late Jurassic (Kimmeridgian to Tithonian dinosaur assemblage, including sauropods (Brachiosaurus, Barosaurus, Dicraeosaurus, Janenschia, theropods (e.g., Elaphrosaurus, Ceratosaurus, Allosaurus, and ornithischians (Kentrosaurus, Dryosaurus. Contrary to the well studied skeletal anatomy of the Tendaguru dinosaurs, the available taphonomic information is rather limited, and a generally accepted taphonomic model has not yet been established. Assessment of unpublished excavation sketches by the German Tendaguru expedition (1909–1913 document bone assemblages of sauropod and ornithischian dinosaurs from the Middle Saurian Bed, Upper Saurian Bed, and the Transitional Sands above the Trigonia smeei Bed, and shed some light on the taphonomy of the Tendaguru dinosaurs. Stages of disarticulation range from incomplete skeletons to solitary bones, and strongly argue for carcass decay and post-mortem transport prior to burial. The sauropod bone accumulations are dominated by adult individuals, and juveniles are rare or missing. The occurrence of bones in different superimposed dinosaur-bearing horizons indicates that skeletal remains were accumulated over a long time span during the Late Jurassic, and the majority of the bone accumulations are probably attritional. These accumulations are likely to have resulted from long-term bone imput due to normal mortality events caused by starvation, seasonal drought, disease, old age and weakness. The depositional environment of the Middle and Upper Saurian Bed was mainly limnic to brackish in origin, while the palaeoenvironment of the Transitional Sands was marginal marine. Tendaguru zählt zu den bedeutendsten Dinosaurier-Lagerstätten Afrikas.

Através de indicadores relativos ao número, à identidade e à sequência de parceiros sexuais ao longo da vida, identificaram-se vários perfis de biografia sexual, desde formas de sexualidade ocasional e de recurso ao sexo pago, mais associadas aos homens, a perfis de parceiro único, mais comuns entre as mulheres. A realização de análises de regressão linear permitiu avaliar o impacto preditivo das biografias sexuais sobre o uso do preservativo e os comportamentos de prevenção. Os dados mostram que as biografias sexuais são importantes para explicar a prevalência do uso de preservativo nas relações com diferentes parceiros. Por outro lado, o receio da infecção e os conhecimentos sobre as formas de transmissão do HIV influenciam a mobilização cognitiva de estratégias de prevenção e de mudança de comportamentos. Todavia, o uso do preservativo parece mais dependente do curso de vida sexual e das interações situadas entre parceiros.On the basis of a representative survey carried out in 2007 of the Portuguese population aged between 18 and 65, this study investigates the impact of factors during the course of sexual life on risk-taking behavior and perceptions among 3055 heterosexual men and women.

We discovered different profiles, from systematic occasional partnerships and use of paid sex, more frequent among men, to the single partner profile, which is more prevalent among women. By carrying out several linear regression analyses, we were able to evaluate the predictive impact of biographical

Donald E. White was a leading scientist for the U.S. Geological Survey, where his career was devoted almost entirely to the study of hydrothermal processes in the Earth’s crust, from the dual perspectives of active geothermal systems and of extinct hydrothermal systems now represented only by ore deposits and alteration patterns. White was devoted to analyzing the mechanisms by which ore-forming metals are concentrated, transported, and deposited. His early work on antimony deposits and on mercury transport led to the understanding that these elements, as well as some precious metals, were concentrated in hydrothermal convection systems characterized by dilute chloride waters of predominantly meteoric origin. He concluded, on the other hand, that base metals required more concentrated brines, as was impressively confirmed in the early 1960s by the discovery of the metal-rich fluids of the Salton Sea geothermal system and subsequently by the recognition of sulfide-depositing hydrothermal systems on the sea floor. His studies of active hot-spring systems elucidated the principles of geyser activity and provided the scientific foundation for research programs aimed at the understanding of geothermal systems throughout the world.

It is illustrated that a theoretical understanding of the formation and evolution of galaxies depends on an understanding of star formation, and especially of the factors influencing the rate of star formation. Some of the theoretical problems of star formation in galaxies, some approaches that have been considered in models of galaxy evolution, and some possible observational tests that may help to clarify which processes or models are most relevant are reviewed. The material is presented under the following headings: power-law models for star formation, star formation processes (conditions required, ways of achieving these conditions), observational indications and tests, and measures of star formation rates in galaxies. 49 references

Full Text Available Biomethanation is a mature technology for fuel production. Fourth generation biofuels research will focus on sequestering CO2 and providing carbon-neutral or carbon-negative strategies to cope with dwindling fossil fuel supplies and environmental impact. Formate is an important intermediate in the methanogenic breakdown of complex organic material and serves as an important precursor for biological fuels production in the form of methane, hydrogen, and potentially methanol. Formate is produced by either CoA-dependent cleavage of pyruvate or enzymatic reduction of CO2 in an NADH- or ferredoxin-dependent manner. Formate is consumed through oxidation to CO2 and H2 or can be further reduced via the Wood-Ljungdahl pathway for carbon fixation or industrially for the production of methanol. Here, we review the enzymes involved in the interconversion of formate and discuss potential applications for biofuels production.

of how the opponent format and relationships impact a game are almost absent in current research. Thus, this paper aims to elucidate how the perception of a competition differs, depending on the opponent format, by presenting a game mechanic framework. The paper furthermore presents an interactive...... football-training platform, as well as games designed to explore the different opponent formats. The games are qualitatively evaluated to illuminate the qualities of and distinctions between different types of opponent formats, proposed by the framework terminology....

today is less about exercising the authority of an office and more about embodying authenticity. I argue that traditional homiletic education can benefit from implementing a learner-centered approach to teaching moving from sermon formation towards preacher formation, in order to develop and train...... preachers. This involves a learning strategy to ministry where theological skills, pastoral competences, and own personality are interwoven. Teaching here means facilitating a room of learning where teacher’s power and control is reduced, allowing the preacher to reflect upon own practice without being...... judged, evaluated, or critiqued. In this paper, I explain how a learner-centered approach to education works in practice and show how pastors experience the teaching method and the congregations’ positive response to their improvements. I shall present the results of a focus-group interview with pastors...

For resources to be shared, sites must be able to exchange basic accounting and usage data in a common format. This document describes a common format which enables the exchange of basic accounting and usage data from different resources. This record format is intended to facilitate the sharing of usage information, particularly in the area of the accounting of jobs, computing, memory, storage and cloud usage but with a structure that allows an easy extension to other resources. This document describes the Usage Record components both in natural language form and annotated XML. This document does not address how these records should be used, nor does it attempt to dictate the format in which the accounting records are stored. Instead, it denes a common exchange format. Furthermore, nothing is said regarding the communication mechanisms employed to exchange the records, i.e. transport layer, framing, authentication, integrity, etc.

National audience; The range of approaches used for clothing virtual characters is large: for incidental characters, the clothing may be no more than a texture map. For lead characters in feature films, full-fledged physical simulation of detailed cloth models may be used. And in the midrange, simple skinning techniques, combined with texture mapping, are common, providing some deformation of clothing as the character moves, but no physical realism. There are three problems one can associate ...
Full Text Available He word “learning” has the endless meanings. The learning occurs not only from knowledge but also as knowledge. Learning in this sense depends not only on our initiative. We cannot just resolve to learn. The whole reliable order can reach deadlock.. The old reliable knowledge and ability mismatchwhile we do not yet have any new possibility. Learning in this sense means a kind of “awakening”, in statu nascendi as the response to a challenge. Thus the condition of learning is sensitiveness to the other or to something, while it is possible via agreement that is not always disposed to us because of our peculiar attitudes. We always think more than we can express. Inevitably, we can do more than we anticipate. Only after the other takes this surplus the knowledge and the ability correspond to reality before they are realized. In learning we are met by another, to which we answer as to something.. This Something is always outstripping the meanings and aspirations. That is why this learning in true sense begins not in us. The destiny of every experience concerning us depends on this, while we cannot anticipate it exactly. Thus, the sense of in statu nascendi corresponds to the saying modo praeterito.
Medical Humanities the journal started life in 2000 as a special edition of the JME. However, the intellectual taproots of the medical humanities as a field of enquiry can be traced to two developments: calls made in the 1920s for the development of multidisciplinary perspectives on the sciences that shed historical light on their assumptions, methods and practices; refusals to assimilate all medical phenomena to a biomedical worldview. Medical humanities the term stems from a desire to situate the significance of medicine as a product of culture. But despite growing usage over half a century the term defies a unifying encapsulation and continues to conjure up a multitude of discourse communities, including scholars working at the interfaces of health and humanities, arts and health, and medical education and bioethics. The field is intellectually capacious and polymorphous, forming and reforming around critical new research questions and teaching tasks spanning disciplines.

Due to the massive use of Internet together with the proliferation of media devices, content based image retrieval has become an active discipline in computer science. A common content based image retrieval approach requires that the user gives a regular image (e.g, a photo) as a query. However, having a regular image as query may be a serious problem. Indeed, people commonly use an image retrieval system because they do not count on the desired image. An easy alternative way t...

The relationship between observable responses and the latent constructs they are purported to measure has received considerable attention recently, with particular focus on what has become known as formative measurement. This alternative to reflective measurement in the area of theory-testing research is examined in the context of the potential for interpretational confounding and a construct's ability to function as a point variable within a larger model. Although these issues have been addressed in the traditional reflective measurement context, the authors suggest that they are particularly relevant in evaluating formative measurement models. On the basis of this analysis, the authors conclude that formative measurement is not an equally attractive alternative to reflective measurement and that whenever possible, in developing new measures or choosing among alternative existing measures, researchers should opt for reflective measurement. In addition, the authors provide guidelines for researchers dealing with existing formative measures. Copyright 2007 APA, all rights reserved.
Isothermal (i.e. time dependent) martensite formation in steel was first observed in the 40ies of the XXth century and is still treated as an anomaly in the description of martensite formation which is considered as a-thermal (i.e. independent of time). Recently, the clarification of the mechanism...... of lattice strains provided fundamental information on the state of stress in the material and clarified the role of the strain energy on martensite formation. Electron backscatter diffraction revealed that the microstructure of the material and the morphology of martensite were independent on the cooling...... leading to isothermal kinetics acquired new practical relevance because of the identification of isothermal martensite formation as the most likely process responsible for enhanced performances of sub-zero Celsius treated high carbon steel products. In the present work, different iron based alloys...

This well stimulation method comprises introducing through the well bore a low-penetrating, dilatant fluid, and subjecting the fluid to sufficient pressure to produce fractures in the formation. The fluid is permitted to remain in contact with the formation so as to become diluted by the formation fluids, and thereby lose its properties of dilatancy. Also, a penetrating fluid, containing a propping agent suspended therein, in introduced into contact with the fractures at a pressure substantially reduced with respect to that pressure which would have been required, prior to the fracturing operation performed using the low-penetrating dilatant fluid. The propping agent is deposited within the fractures, and thereafter, fluid production is resumed from the fractured formation. (2 claims)
Low-mass stars form through a process known as disk accretion, eating up material that orbits in a disk around them. It turns out that the same mechanism also describes the formation of more massive stars.

The research in this study identified formate dehydrogenase, an enzyme that plays a metabolic role on the periphery of one-carbon metabolism, has an unusual localization in Arabidopsis thaliana and that the enzyme has an unusual kinetic plasticity. These properties make it possible that this enzyme could be engineered to attempt to engineer plants with an improved photosynthetic efficiency. We have produced transgenic Arabidopsis and tobacco plants with increased expression of the formate dehydrogenase enzyme to initiate further studies.
Blister formation in metals has been observed during bombardment with inert-gas ions in the energy range between 1 and 2000 keV at doses of about 10 17 to 10 19 cm -2 . The changes in surface topography and the erosion yields were mainly studied in the scanning electron microscope (SEM). Additionally the release of the implanted gas during blister formation was observed. Recently measurements on single crystals were performed determining simultaneously the implantation profile, the total amount of trapped ions, the depth distribution of the induced lattice damage and the thickness of the covers of the blisters. In several stages of the formation process of blisters the implanted layer was observed in the transmission electron microscope (TEM) showing the formation of gas bubbles. Using the results of all these measurements in this review an attempt is made to develop a model of blister formation combining the effects of hydrostatic pressure in the gas bubbles and lateral stress due to volume swelling.

The vascular system developed early in evolution. It is required in large multicellular organisms for the transport of nutrients, oxygen, and waste products to and from tissues. The vascular system is composed of hollow tubes, which have a high level of complexity in vertebrates. Vasculogenesis describes the de novo formation of blood vessels, e.g., aorta formation in vertebrate embryogenesis. In contrast, angiogenesis is the formation of blood vessels from preexisting ones, e.g., sprouting of intersomitic blood vessels from the aorta. Importantly, the lumen of all blood vessels in vertebrates is lined and formed by endothelial cells. In both vasculogenesis and angiogenesis, lumen formation takes place in a cord of endothelial cells. It involves a complex molecular mechanism composed of endothelial cell repulsion at the cell-cell contacts within the endothelial cell cords, junctional rearrangement, and endothelial cell shape change. As the vascular system also participates in the course of many diseases, such as cancer, stroke, and myocardial infarction, it is important to understand and make use of the molecular mechanisms of blood vessel formation to better understand and manipulate the pathomechanisms involved.

We show that in a standardized in vitro flow system unencapsulated variants of genetically diverse lineages of Neisseria meningitidis formed biofilms, that could be maintained for more than 96 h. Biofilm cells were resistant to penicillin, but not to rifampin or ciprofloxacin. For some strains......, microcolony formation within biofilms was observed. Microcolony formation in strain MC58 depended on a functional copy of the pilE gene encoding the pilus subunit pilin, and was associated with twitching of cells. Nevertheless, unpiliated pilE mutants formed biofilms showing that attachment and accumulation......X alleles was identified among genetically diverse meningococcal strains. PilX alleles differed in their propensity to support autoaggregation of cells in suspension, but not in their ability to support microcolony formation within biofilms in the continuous flow system....
When nitrogen was selected as the glovebox atmosphere for the Replacement Tritium Facility (RTF) at the Savannah River Site (SRS), a concern was raised as to the possibility of tritiated ammonia formation in the gloveboxes. Experimental data were produced to study the tritiated ammonia formation rate in a tritium and nitrogen mixture. A rate equation that closely simulates the experimental data was developed. This rate equation can be used to calculate the formation of tritiated ammonia from different concentrations of tritium and nitrogen. The reaction of T 2 and N 2 to form NT 3 is a slow process, particularly when the tritium concentration is low. The reaction requires weeks or months to reach radiochemical equilibrium dependent on the concentrations of the reactants. 4 refs., 6 figs., 1 tab

The rapidly expanding field of galaxy formation lies at the interface between astronomy, particle physics, and cosmology. Covering diverse topics from these disciplines, all of which are needed to understand how galaxies form and evolve, this book is ideal for researchers entering the field. Individual chapters explore the evolution of the Universe as a whole and its particle and radiation content; linear and nonlinear growth of cosmic structure; processes affecting the gaseous and dark matter components of galaxies and their stellar populations; the formation of spiral and elliptical galaxies; central supermassive black holes and the activity associated with them; galaxy interactions; and the intergalactic medium. Emphasizing both observational and theoretical aspects, this book provides a coherent introduction for astronomers, cosmologists, and astroparticle physicists to the broad range of science underlying the formation and evolution of galaxies.

Planets form in gaseous protoplanetary disks surrounding newborn stars. As such, the most direct way to learn how they form from observations, is to directly watch them forming in disks. In the past, this was very difficult due to a lack of observational capabilities; as such, planet formation was largely a subject of pure theoretical astrophysics. Now, thanks to a fleet of new instruments with unprecedented resolving power that have come online recently, we have just started to unveil features in resolve images of protoplanetary disks, such as gaps and spiral arms, that are most likely associated with embedded (unseen) planets. By comparing observations with theoretical models of planet-disk interactions, the masses and orbits of these still forming planets may be constrained. Such planets may help us to directly test various planet formation models. This marks the onset of a new field — observational planet formation. I will introduce the current status of this field.

This chapter proposes that organizational strategy formation should be characterized theoretically as a process that is subject to several interacting forces, rather than represented by separate discrete decisionmodels or theoretic perspectives, as is commonly done in the strategic management...... literature. Based on an extensive review of relevant theory and empirical work in strategic decision-making, organizational change theory, cognitive and social psychology, and strategy processes, seven kinds of ''forces'' - rational, imposed, teleological, learning, political, heuristic, and social...... - are identified as interacting in and having significant influence on the strategy formation process. It is further argued that by applying a holistic ''forces-view'' of the significant and interacting influences on strategy formation, we can better understand the dynamics and challenges in managing the process...
The first step in the standard model for planet formation is the growth of gravitationally bound bodies called ``planetesimals'' from dust grains in a protoplanetary disk. Currently, we do not know how planetesimals form, how long they take to form, or what their sizes and mechanical properties are. The goal of this proposal is to assess how these uncertainties affect subsequent stages of planetary growth and the kind of planetary systems that form. The work will address three particular questions: (i) Can the properties of small body populations in the modern Solar System constrain the properties of planetesimals? (ii) How do the properties of planetesimals affect the formation of giant planets? (iii) How does the presence of a water ice condensation front (the ``snow line'') in a disk affect planetesimal formation and the later stages of planetary growth? These questions will be examined with computer simulations of planet formation using new computer codes to be developed as part of the proposal. The first question will be addressed using a statistical model for planetesimal coagulation and fragmentation. This code will be merged with the proposer's Mercury N-body integrator code to model the dynamics of large protoplanets in order to address the second question. Finally, a self- consistent model of disk evolution and the radial transport of water ice and vapour will be added to examine the third question. A theoretical understanding of how planets form is one of the key goals of NASA and the Origins of Solar Systems programme. Researchers have carried out many studies designed to address this goal, but the questions of how planetesimals form and how their properties affect planet formation have received relatively little attention. The proposed work will help address these unsolved questions, and place other research in context by assessing the importance of planetesimal origins and properties for planet formation.

The spatial distribution of Galaxies and Galaxy congestions in the southern galactic hemisphere is studied. The rich galaxy congestions, containing many elliptic Galaxies and radiogalaxies, are linked with each other by chains of scanty congestions with moderate content of elliptic Galaxies and radiogalaxies. The flat formation, linking the density pikes and the intermediate chains, can reasonably be called supercongestion. In the central region of supercongestions there is a thin layer of Galaxies consisting of only spiral Galaxies. The neighbouring supercongestions touch each other, while the intersupercongestion space contains no Galaxy congestions and almost no Galaxies. It is shown that such a structure was, apparently, formed before the formation of Galaxies
The present theories of galaxy formation are reviewed. The relation between peculiar velocities and the correlation function of galaxies points to the possibility that galaxies do not form uniformly everywhere. Scale invariant properties of the cluster-cluster correlations are discussed. Comparing the correlation functions in a dimensionless way, galaxies appear to be stronger clustered, in contrast with the comparison of the dimensional amplitudes of the correlation functions. Theoretical implications of several observations as Lyman-α clouds, correlations of faint galaxies are discussed. None of the present theories of galaxy formation can account for all facts in a natural way. 29 references

Full Text Available Research objective: to introduce into academic circulation previously unknown source on the Golden Horde history. Research materials: biographical dictionary of Taqi al-Din al-Maqrizi (766/1365 – 845/1441 “Kitab al-Muqaffa al-Kabir” (The Great Rhymed Book. Results and novelty of the research: This article contains materials from the works of historians engaged in the narrative biography, which V.G. Tiesenhausen did not include in his “Collection of Materials on the Golden Horde history (extract from Arab writings”, although their writings contain very valuable information about the Golden Horde History. Research novelty consists in the fact that the author of this article presents one paragraph from biographical dictionary of Taqi al-Din al-Maqrizi, whose article number 421 provides information about a scholar from Saray – Mawlana Zada al-Sarayi. The author provides its translation and commentary referring to the more than ten medieval Arab sources. After receiving basic education at home, Mawlana Zada al-Sarayi traveled to many Eastern countries in search of knowledge and after having received high recognition he settled in Cairo as a teacher of Sharia Sciences. Despite the fact that his life was interrupted at an early age (36 years, he left a deep mark in science. His son Muhibbu al-Din (Cairo, 791/1389 – Mecca, Friday, the 3rd of Dhu al-Hijjah 859/13 November 1455 also became a great scholar as well as an imam of Sultan al-Ashraf Barsbay himself and other sultans after him. Nisba al-Sarayi sounded on the lips of the Ulema of the East as a symbol of learnedness and high temper. As a result of research it must be said that the study of life of Mawlana Zada al-Sarayi (754/1353 – 791/1389 and the number of migrants from Desht-i Kipchak in Egypt will help researchers in a deeper and more detailed study of the Golden Horde history.
The solution for electrostatic potential within a simply modeled tandem mirror thermal barrier is seen to exhibit a sheath at each edge of the cell. The formation of the sheath requires ion collisionality and the analysis assmes that the collisional trapping rate into the barrier is considerably slower than the barrier pump rate
We consider the formation of point and line topological defects (monopoles and strings) from a general point of view by allowing the probability of formation of a defect to vary. To investigate the statistical properties of the defects at formation we give qualitative arguments that are independent of any particular model in which such defects occur. These arguments are substantiated by numerical results in the case of strings and for monopoles in two dimensions. We find that the network of strings at formation undergoes a transition at a certain critical density below which there are no infinite strings and the closed-string (loop) distribution is exponentially suppressed at large lengths. The results are contrasted with the results of statistical arguments applied to a box of strings in dynamical equilibrium. We argue that if point defects were to form with smaller probability, the distance between monopoles and antimonopoles would decrease while the monopole-to-monopole distance would increase. We find that monopoles are always paired with antimonopoles but the pairing becomes clean only when the number density of defects is small. A similar reasoning would also apply to other defects
The presently fashionable ideas for galaxy formation are reviewed briefly, and it is concluded that the standard isothermal heirarchy fits the available data best. A simple infall picture is presented which explains many of the observed properties of disk galaxies. (orig.)

Chlorination is the most important method of disinfection in Malaysia which aims at ensuring an acceptable and safe drinking water quality. The dosing of chlorine to surface water containing ammonia and nitrogen compounds may form chloramines in the treated water. During this reaction, inorganic and organic chloramines are formed. The recommended maximum acceptable concentration (MAC) for chloramines in drinking water is 3000 μg/L. The production of monochloramine, dichloramine and trichloramine is highly dependent upon pH, contact time and the chlorine to ammonia molar ratio. The purpose of this study is to examine the formation of chloramines that occur upon the chlorination during the treatment process. Chloramines were determined using the N,N-diethyl-p-phenylenediamine (DPD) colorimetric method. The influences of ammonia, pH and chlorine dosage on the chloramines formation were also studied. This paper presents a modeling approach based on regression analysis which is designed to estimate the formation of chloramines. The correlation between the concentration of chloramines and the ammonia, pH and chlorine dosage was examined. In all cases, the quantity of chloramines formed depended linearly upon the amount of chlorine dosage. On the basis of this study it reveals that the concentration of chloramines is a function of chlorine dosage and the ammonia concentration to the chlorination process. PH seems to not significantly affect the formation of chloramines. (author)

Experiments on both stationary and propagating double layers and a related analytical model are described. Stationary double layers were produced in a multiple plasma device, in which an electron drift current was present. An investigation of the plasma parameters for the stable double layer condition is described. The particle distribution in the stable double layer establishes a potential profile, which creates electron and ion beams that excite plasma instabilities. The measured characteristics of the instabilities are consistent with the existence of the double layer. Propagating double layers are formed when the initial electron drift current is large. Ths slopes of the transition region increase as they propagate. A physical model for the formation of a double layer in the experimental device is described. This model explains the formation of the low potential region on the basis of the space charge. This space charge is created by the electron drift current. The model also accounts for the role of ions in double layer formation and explains the formation of moving double layers. (Auth.)
Full Text Available The formation of life competences is the result of a quality education that prepares students to meet the challenges of a fast moving world where equality and equal opportunities should constitute premises of education; training them is a challenge teachers to assume new generations contribute actively to a better world. In Cuba are important research on the formation of communication competences and self-regulated learning in primary school. The paper shows the result of an investigation that provides a methodology for the formation of life competences in primary school education, used as an essential pathway research activity. The methodological approach of research has a quantitative approach and an explanatory scope to establish and make sense of understanding the causal relationship between the direction of research activity and training of life competences. Theoretical, empirical and mathematical-statistical, for characterizing the initial state, processing of results and analysis: research methods are used. The application of the methodology for the formation of life competences makes teachers lead the teaching-learning process with a research and transforming teaching concept, where the school is the protagonist of their learning and causes changes in their performances, which are evident in the formed competences related to effective and affective communication; the solution of problems related to life; the use of means in obtaining the knowledge and the expression of a behavior consistent with school and social demands. The effectiveness of the methodology confirms that there is a causal relationship between the direction of research activity by teachers and the formation of life competences in school.
(Released 10 April 2002) The Science This THEMIS visible image was acquired near 7o S, 172o W (188o E) and shows a remarkable martian geologic deposit known as the Medusae Fossae Formation. This Formation, seen here as the raised plateau in the upper two-thirds of the image, is a soft, easily eroded deposit that extends for nearly 1,000 km along the equator of Mars. In this region the deposit has been heavily eroded by the wind to produce a series of linear ridges called yardangs. These parallel ridges point in direction of the prevailing winds that carved them, and demonstrate the power of martian winds to sculpt the dry landscape of Mars. The Medusae Fossae Formation has been completely stripped from the surface in the lower third of the image, revealing a harder layer below that is more resistant to wind erosion. The easily eroded nature of the Medusae Fossae Formation suggests that it is composed of weakly cemented particles, and was most likely formed by the deposition of wind-blown dust or volcanic ash. Several ancient craters that were once completely buried by this deposit are being exposed, or exhumed, as the overlying Medusae Formation is removed. Very few impact craters are visible on this Formation, indicating that the surface seen today is relatively young, and that the processes of erosion are likely to be actively occurring. The Story Medusa of Greek mythology fame, the name-giver to this region, had snaky locks of hair that could turn a person to stone. Wild and unruly, this monster of the underworld could certainly wreak havoc on the world of the human imagination. As scary as she was, Medusa would have no advantage over the fierce, masterful winds blowing across Mars, which once carved the streaky, terrain at the top of this image. Wild and whipping, these winds have slowly eroded away the 'topsoil,' revealing ancient craters and other surface features they once covered. The loosely cemented particles of this 'topsoil' are likely made up of dust

The measured breakdown curves for H 2 , A and He are compared with the predictions of a simple model with reasonable agreement. The influence of stray magnetic fields in the plasma formation is investigated and conditions are chosen to facilitate the breakdown. The time profile of loop voltage and plasma current for shots with plasma equilibrium are shown. A comparison is made between experimental results and analytical-numerical model for tokamaks discharges with ohmic heating. Reasonable agreement is obtained when Z, effective atomic number, is assumed as a parameter. (Author) [pt

A theoretical study of the formation of a coronal cavity and its relation to a quiescent prominence is presented. It is argued that the formation of a cavity is initiated by the condensation of plasma which is trapped by the coronal magnetic field in a closed streamer and which then flows down to the chromosphere along the field lines due to lack of stable magnetic support against gravity. The existence of a coronal cavity depends on the coronal magnetic field strength; with low strength, the plasma density is not high enough for condensation to occur. Furthermore, we suggest that prominence and cavity material is supplied from the chromospheric level. Whether a coronal cavity and a prominence coexist depends on the magnetic field configuration; a prominence requires stable magnetic support

We present a model for the formation of the recently-discovered TRAPPIST-1 planetary system. In our scenario planets form in the interior regions, by accretion of mm to cm-size particles (pebbles) that drifted from the outer disk. This scenario has several advantages: it connects to the observation that disks are made up of pebbles, it is efficient, it explains why the TRAPPIST-1 planets are ˜Earth mass, and it provides a rationale for the system's architecture.

While interest in developing strategic alliances within the food system continues to increase, there remains considerable risk when firms adopt such a cooperative strategy. The risk is due in part to the lack of concrete guidelines that illustrate the steps or stages of alliance development and the important strategic and operational decisions required at each stage. The existence of such guidelines would facilitate alliance formation and enable managers and researchers to better understand a...
Full Text Available The contemporaneity is characterized by instability and diversity calling into question certainties and truths proposed in modernity. We recognize that the reality of things and phenomena become effective as a set of events, interactions, retroactions and chances. This different frame extends the need for revision of the epistemological foundations that sustain educational practices and give them sense. The complex thinking is an alternative option for acting as a counterpoint to classical science and its reductionist logic and knowledge compartmentalization, as well as to answer to contemporary epistemological and educational challenges. It aims to associate different areas and forms of knowledge, without, however merge them, distinguishing without separating the several disciplines and instances of the realities. This study, in theoretical references, highlights the relevance of complex approaches to support formative experiences because also able to produce complexities in reflections about educational issues. We conclude that formative possibilities from complexity potentialize the resignification of human’s conception and the understanding of its singularity in interdependence; The understanding that pedagogical and educational activities is a constant interrogation about the possibilities of knowing the knowledge and reframe learning, far beyond knowing its functions and utilitarian purposes; and, as a formative possibility, places us on the trail of responsibility, not as something eventual, but present and indicative of freedom to choose to stay or go beyond.

Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets. This information helps to guide numerical models for the three stages of planet formation from dust to planetesimals (~10(6) y), followed by planetesimals to embryos (lunar to Mars-sized objects; few 10(6) y), and finally embryos to planets (10(7)-10(8) y). Defining the role of turbulence in the early nebula is a key to understanding the growth of solids larger than meter size. The initiation of runaway growth of embryos from planetesimals ultimately leads to the growth of large terrestrial planets via large impacts. Dynamical models can produce inner Solar System configurations that closely resemble our Solar System, especially when the orbital effects of large planets (Jupiter and Saturn) and damping mechanisms, such as gas drag, are included. Experimental studies of terrestrial planet interiors provide additional constraints on the conditions of differentiation and, therefore, origin. A more complete understanding of terrestrial planet formation might be possible via a combination of chemical and physical modeling, as well as obtaining samples and new geophysical data from other planets (Venus, Mars, or Mercury) and asteroids.

This method of propping fractured formations results in high conductivities. In the method, certain naturally occurring crystals are used as propping agents. Suitable crystals include garnet, corundum, zircon, rutile, high-temperature quartz, and other minerals which have Moh's hardness values of about 6 or greater and weather out as individual crystals of about 40 mesh or larger. These are said to result in permeabilities significantly higher than those obtained with ordinary quartz sand, metallic shot, glass beads, plastic particles, walnut hulls, or similar materials.

A study of the structure of superclusters in the Southern galactic hemisphere using Zwicky clusters as principal tracers of the large-scale structure of the Universe is reported. The data presented suggest that the formation of galaxies was a two stage process involving larger spatial dimensions than earlier workers have postulated. In the first stage proto-superclusters and big holes had to form from the non-dissipative dark matter while in the second hot gas, by cooling and settling down into the potential wells caused by dark matter, will form galaxies and clusters of galaxies.

The formation of slums need not be inevitable with rapid urbanization. Such an argument appears to be contradicted by evidence of large slum populations in a large number of developing countries and particularly in rapidly urbanizing regions like Asia. The evidence discussed suggests that city authorities faced with rapid urban development lack the capacity to cope with the diverse demands for infrastructural provision to meet economic and social needs. Not only are strategic planning and intervention major issues in agenda to manage rapid urbanization, but city governments are not effectively linking the economic development trajectory to implications for urban growth and, hence, housing needs. In the following discussion, a case study is presented in support of the argument that city governments have to first recognize and then act to establish the link that is crucial between economic development, urban growth, and housing. This is the agendum that has been largely neglected by city and national governments that have been narrowly focused on economic growth with the consequent proliferation of slum formation as a housing solution.

It seemed appropriate to devote the 1980 School to the origin of the solar system and more particularly to the formation of planetary systems (dynamic accretion processes, small bodies, planetary rings, etc...) and to the physics and chemistry of planetary interiors, surface and atmospheres (physical and chemical constraints associated with their formation). This Summer School enabled both young researchers and hard-nosed scientists, gathered together in idyllic surroundings, to hold numerous discussions, to lay the foundations for future cooperation, to acquire an excellent basic understanding, and to make many useful contacts. This volume reflects the lectures and presentations that were delivered in this Summer School setting. It is aimed at both advanced students and research workers wishing to specialize in planetology. Every effort has been made to give an overview of the basic knowledge required in order to gain a better understanding of the origin of the solar system. Each article has been revised by one or two referees whom I would like to thank for their assistance. Between the end of the School in August 1980 and the publication of this volume in 1982, the Voyager probes have returned a wealth of useful information. Some preliminary results have been included for completeness

We describe a 1,400 million-year old (Ma) iron formation (IF) from the Xiamaling Formation of the North China Craton. We estimate this IF to have contained at least 520 gigatons of authigenic Fe, comparable in size to many IFs of the Paleoproterozoic Era (2,500–1,600 Ma). Therefore, substantial IFs formed in the time window between 1,800 and 800 Ma, where they are generally believed to have been absent. The Xiamaling IF is of exceptionally low thermal maturity, allowing the preservation of organic biomarkers and an unprecedented view of iron-cycle dynamics during IF emplacement. We identify tetramethyl aryl isoprenoid (TMAI) biomarkers linked to anoxygenic photosynthetic bacteria and thus phototrophic Fe oxidation. Although we cannot rule out other pathways of Fe oxidation, iron and organic matter likely deposited to the sediment in a ratio similar to that expected for anoxygenic photosynthesis. Fe reduction was likely a dominant and efficient pathway of organic matter mineralization, as indicated by organic matter maturation by Rock Eval pyrolysis combined with carbon isotope analyses: Indeed, Fe reduction was seemingly as efficient as oxic respiration. Overall, this Mesoproterozoic-aged IF shows many similarities to Archean-aged (>2,500 Ma) banded IFs (BIFs), but with an exceptional state of preservation, allowing an unprecedented exploration of Fe-cycle dynamics in IF deposition.
Full Text Available Enamel formation requires consecutive stages of development to achieve its characteristic extreme mineral hardness. Mineralization depends on the initial presence then removal of degraded enamel proteins from the matrix via endocytosis. The ameloblast membrane resides at the interface between matrix and cell. Enamel formation is controlled by ameloblasts that produce enamel in stages to build the enamel layer (secretory stage and to reach final mineralization (maturation stage. Each stage has specific functional requirements for the ameloblasts. Ameloblasts adopt different cell morphologies during each stage. Protein trafficking including the secretion and endocytosis of enamel proteins is a fundamental task in ameloblasts. The sites of internalization of enamel proteins on the ameloblast membrane are specific for every stage. In this review, an overview of endocytosis and trafficking of vesicles in ameloblasts is presented. The pathways for internalization and routing of vesicles are described. Endocytosis is proposed as a mechanism to remove debris of degraded enamel protein and to obtain feedback from the matrix on the status of the maturing enamel.

An international network of co-operating data centres is described who maintain identical data bases which are simultaneously updated by an agreed data exchange procedure. The agreement covers ''data exchange formats'' which are compatible to the centres' internal data storage and retrieval systems which remain different, optimized at each centre to the available computer facilities and to the needs of the data users. Essential condition for the data exchange is an agreement on common procedures for the data exchange is an agreement on common procedures for the data compilation, including critical data analysis and validation. The systems described (''EXFOR'', ''ENDF'', ''CINDA'') are used for ''nuclear reaction data'', but the principles used for data compilation and exchange should be valid also for other data types.

Anyone who has ever used baking soda instead of baking powder when trying to make a cake knows a simple truth: ingredients matter. The same is true for planet formation. Planets are made from the materials that coalesce in a rotating disk around young stars - essentially the "leftovers" from when the stars themselves formed through the gravitational collapse of rotating clouds of gas and dust. The planet-making disk should therefore initially have the same gas-to-dust ratio as the interstellar medium: about 100 to 1, by mass. Similarly, it seems logical that the elemental composition of the disk should match that of the star, reflecting the initial conditions at that particular spot in the galaxy.

The formation of a small incendiary spark at atmospheric pressure is identified with the transition from a weakly to a strongly ionized plasma. It is shown that initial gaseous ionization produced by avalanches and/or streamers always creates a high-temperature ideal electron gas that can shield the applied voltage difference and reduce ionization in the volume of the gas. The electron gas is collision dominated but able to maintain its high temperature, for times long compared to discharge events, through long-range Coulomb forces. In fact, electrons in the weakly ionized plasma constitute a collisionless independent fluid with a thermodynamic state that can be affected directly by field or density changes. Accordingly, with metal electrodes, cathode spot emission is always associated with the transition to a strongly ionized plasma. Neutral heating can be accomplished in two different ways. Effective dispersal of the electrons from the cathode leads to electron heating dominated by diffusion effects. Conversely, a fast rate of emission or rapid field changes can produce nonlinear wave propagation. It is shown that solitary waves are possible, and it is suggested that some spark transitions are associated with shock waves in the collisionless electron gas. In either the diffuse or nonlinear regime, neutral gas heating is controlled by collisions of ions with isotropic thermal electrons. This interaction is always subsequent to changes in state of the electron gas population. The basic results obtained should apply to all sparks

Radiographic imaging continues to be a key diagnostic in many areas at Los Alamos National Laboratory (LANL). Radiographic recording systems have taken on many form, from high repetition-rate, gated systems to film recording and storage phosphors. Some systems are designed for synchronization to an accelerator while others may be single shot or may record a frame sequence in a dynamic radiography experiment. While film recording remains a reliable standby in the radiographic community, there is growing interest in investigating electronic recording for many applications. The advantages of real time access to remote data acquisition are highly attractive. Cooled CCD camera systems are capable of providing greater sensitivity with improved signal-to-noise ratio. This paper begins with a review of performance characteristics of the Bechtel Nevada large format imaging system, a gated system capable of viewing scintillators up to 300 mm in diameter. We then examine configuration alternatives in lens coupled and fiber optically coupled electro-optical recording systems. Areas of investigation include tradeoffs between fiber optic and lens coupling, methods of image magnification, and spectral matching from scintillator to CCD camera. Key performance features discussed include field of view, resolution, sensitivity, dynamic range, and system noise characteristics

The relations between star formation and gas have received renewed attention. We combine studies on scales ranging from local (within 0.5 kpc) to distant galaxies to assess what factors contribute to star formation. These include studies of star forming regions in the Milky Way, the LMC, nearby galaxies with spatially resolved star formation, and integrated galaxy studies. We test whether total molecular gas or dense gas provides the best predictor of star formation rate. The star formation ``efficiency," defined as star formation rate divided by mass, spreads over a large range when the mass refers to molecular gas; the standard deviation of the log of the efficiency decreases by a factor of three when the mass of relatively dense molecular gas is used rather than the mass of all the molecular gas. We suggest ways to further develop the concept of "dense gas" to incorporate other factors, such as turbulence.

STUDIES OF PARACRYSTAL FORMATION BY COLUMN PURIFIED LIGHT MEROMYOSIN (LMM) PREPARED IN A VARIETY OF WAYS LED TO THE FOLLOWING CONCLUSIONS: (a) different portions of the myosin rod may be coded for different stagger relationships. This was concluded from observations that paracrystals with different axial repeat periodicities could be obtained either with LMM framents of different lengths prepared with the same enzyme, or with LMM fragments of identical lengths but prepared with different enzymes. (b) Paracrystals with a 14-nm axial repeat periodicity are most likely formed by the aggregation of sheets with a 44-nm axial repeat within the sheets which are staggered by 14 nm. All of the axial repeat patterns expected from one sheet or aggregates of more than one sheet, on this basis, were observed in the same electron micrograph. (c) C-protein binding probably occurs preferentially to LMM molecules related in some specific way. This was concluded from the observation that the same axial repeat pattern was obtained in paracrystals formed from different LMM preparations in the presence of C-protein, regardless of differences in the axial repeat obtained in the absence of C-protein. (d) Nucleic acid is responsible for the 43-nm axial repeat patterns observed in paracrystals formed by the ethanol-resistant fraction of LMM. In the absence of nuclei acid, paracrystals with a 14nm axial repeat are obtained. (e) The 43-nm axial repeat pattern observed with the ethanol-resistant fraction of LMM is different for LMM preparations obtained by trypsin and papain digestions.

Using atomic force microscopy, we find that the surface morphology of a dissolving aluminum anode in a commercial electropolishing electrolyte can exhibit both highly regular and randomly packed stripe and hexagonal patterns with amplitudes of about 5 nm and wavelengths of 100 nm. The driving instability of this pattern formation phenomenon is proposed to be the preferential adsorption of polar or polarizable organic molecules on surface ridges where the contorted double layer produces a higher electric potential gradient. The enhanced relative coverage shields the anode and induces a smaller dissolution rate at the ridges. The instability is balanced by surface diffusion of the adsorbate to yield a length scale of 4π(D s /k d ) 1/2 , where D s is the surface diffusivity and k d is the desorption coefficient of the adsorbate, which correlates well with the measured wavelength. A long-wavelength expansion of the double-layer field yields an interface evolution equation that reproduces all of the observed patterns. In particular, bifurcation analysis and numerical simulation yield a single voltage-dependent dimensionless parameter ξ that measures a balance between smoothing of adsorbate concentration by electric-field-dependent surface diffusion and fluctuation due to interfacial curvature and stretching. Randomly oriented stripes are favored at large ξ (low voltage), while random hills dominate at small ξ (high voltage) with perfectly periodic stripes and hexagonal hill patterns within a small window near ξ=1. These predictions are in qualitative and quantitative agreement with our measurements. copyright 1997 The American Physical Society

Information that is congruent with existing knowledge (a schema) is usually better remembered than less congruent information. Only recently, however, has the role of schemas in memory been studied from a systems neuroscience perspective. Moreover, incongruent (novel) information is also sometimes better remembered. Here, we review lesion and neuroimaging findings in animals and humans that relate to this apparent paradoxical relationship between schema and novelty. In addition, we sketch a framework relating key brain regions in medial temporal lobe (MTL) and medial prefrontal cortex (mPFC) during encoding, consolidation and retrieval of information as a function of its congruency with existing information represented in neocortex. An important aspect of this framework is the efficiency of learning enabled by congruency-dependent MTL-mPFC interactions. Copyright © 2012 Elsevier Ltd. All rights reserved.

Formation of interstellar anions: M.L. Senent. The recent detection of negative charged species in the ISM1 has instigated enthusiasm for anions in the astrophysical community2. Many of these species are new and entail characterization. How they are formed in astrophysical sources is a question of major relevance. The anion presence in ISM was first predicted theoretically on the basis of electron affinities and on the negative linear chain molecular stabilities. Although very early, they were considered in astrochemical models3-4, their discovery is so recent because their abundances seem to be relatively low. These have to be understood in terms of molecular stabilities, reaction probabilities and radiative and collisional excitations. Then, we present our theoretical work on even carbon chains type Cn and CnH (n=2,4,6) focused to the understanding of anion abundances. We use highly correlated ab initio methods. We performed spectroscopic studies of various isomers that can play important roles as intermediates5-8. In previous papers9-10, we compared C2H and C2H- collisional rates responsible for observed line intensities. Actually, we study hydrogen attachment (Cn +H → CnH and Cn- +H → CnH-) and associative detachment processes (Cn- +H → CnH +e-) for 2, 4 and 6 carbon atom chains11.

This book systematically describes the concepts and principles for multi-satellite relative motion, passive and near passive formation designs, trajectory planning and control for fuel optimal formation maneuvers, and formation flying maintenance control design. As such, it provides a sound foundation for researchers and engineers in this field to develop further theories and pursue their implementations. Though satellite formation flying is widely considered to be a major advance in space technology, there are few systematic treatments of the topic in the literature. Addressing that gap, the book offers a valuable resource for academics, researchers, postgraduate students and practitioners in the field of satellite science and engineering.

We develop a simple semianalytic model of the star formation rate as a function of time. We estimate the star formation rate for a wide range of values of the cosmological constant, spatial curvature, and primordial density contrast. Our model can predict such parameters in the multiverse, if the underlying theory landscape and the cosmological measure are known.

Full Text Available We have developed a unified format for phylogenetic placements, that is, mappings of environmental sequence data (e.g., short reads into a phylogenetic tree. We are motivated to do so by the growing number of tools for computing and post-processing phylogenetic placements, and the lack of an established standard for storing them. The format is lightweight, versatile, extensible, and is based on the JSON format, which can be parsed by most modern programming languages. Our format is already implemented in several tools for computing and post-processing parsimony- and likelihood-based phylogenetic placements and has worked well in practice. We believe that establishing a standard format for analyzing read placements at this early stage will lead to a more efficient development of powerful and portable post-analysis tools for the growing applications of phylogenetic placement.
A technique is provided for assaying the formations surrounding a borehole for uranium. A borehole logging tool cyclically irradiates the formations with neutrons and responds to neutron fluxes produced during the period of time that prompt neutrons are being produced by the neutron fission of uranium in the formations. A borehole calibration tool employs a steady-state (continuous output) neutron source, firstly, to produce a response to neutron fluxes in models having known concentrations of uranium and, secondly, to to produce a response to neutron fluxes in the formations surrounding the borehole. The neutron flux responses of the borehole calibration tool in both the model and the formations surrounding the borehole are utilized to correct the neutron flux response of the borehole logging tool for the effects of epithermal/thermal neutron moderation, scattering, and absorption within the borehole itself
Geologic factors of hydrogenic uranium deposit formation are considered. Structural, formation and lithological-facies factors of deposit formation, connected with zones of stratal oxidation, are characterized. Peculiarities of deposit localization, connected with orogenic structures of Mesozoic and lenozoic age, are described. It is noted that deposits of anagenous group are widely spread in Paleozoic formations, infiltration uranium deposits are localized mainly in Cenozoic sediments, while uranium mineralization both anagenous and infiltration groups are widely developed in Mesozoic sediments. Anagenous deposits were formed in non-oxygen situation, their age varies from 200 to 55 mln years. Infiltration deposit formation is determined by asymmetric oxidation zonation, their age varies from 10 - 40 mln years to dozens of thousand years [ru
Autobiographical reasoning is the activity of creating relations between different parts of one's past, present, and future life and one's personality and development. It embeds personal memories in a culturally, temporally, causally, and thematically coherent life story. Prototypical autobiographical arguments are presented. Culture and socializing interactions shape the development of autobiographical reasoning especially in late childhood and adolescence. Situated at the intersection of cognitive and narrative development and autobiographical memory, autobiographical reasoning contributes to the development of personality and identity, is instrumental in efforts to cope with life events, and helps to create a shared history.

Full Text Available In this paper, I explore the relationship between an artifact's biography and the raw material from which it was made. Specifically, I discuss the biographies of groundstone tools from five Late Neolithic and Chalcolithic (3500-2000 BC sites in lowland Portugal. An analysis of the formal and material characteristics of tools (totalling over 1300 from these sites indicates that the raw material from which a tool was made not only constrained the form and function of that tool, but also determined, to a large extent, whether that tool would be recycled and the context (settlement V5. burial in which that tool would be ultimately deposited. I suggest that both the material properties and the socio-symbolic associations of different raw materials might explain the biographies of the artifacts from which they were made.
En este trabajo, exploro las relaciones entre la biografía del artefacto y la materia prima a partir de la cual se hizo. Específicamente discuto las biografías de los útiles de piedra pulimentada de cinco sitios del Neolítico Final y Calcolítico (3500-2000 AC de las tierras bajas portuguesas. El análisis de las características formales y materiales de los útiles (unos 1300 en total de estos sitios indica que la materia prima a partir de la cual se hizo un utensilio no sólo limitó su forma y función, sino que también determinó, en gran medida, si sería reciclado y el contexto (poblado vs enterramiento en el que sería finalmente depositado. Sugiero que tanto las propiedades materiales como las asociaciones socio-simbólicas de las diferentes materias primas a partir de las cuales se hicieron los artefactos pueden explicar sus biografías.

Full Text Available Background: Employability is the capacity of employees to acquire transferable competencies and individual capacities that enable them to adapt to, be innovative in and steer their own careers in a dynamic work environment. It is clear that employers would thus look for employees who are capable of proactive adjustment and action-oriented behaviours. Aim: The aim of the study was to determine whether significant differences exist in the employability attributes of individuals from different gender, race and age groups and if so, how should such a diverse workforce should be managed. Setting: This study was conducted at a distance education institution. The sample of respondents consisted of adult learners who are pursuing further distance learning studies in the economic and management sciences field in South Africa. Methods: Correlational and inferential statistical analyses were used. A stratified random sample of 1102 mainly black and female adult learners participated in the study. Results: The employability attributes framework identified three categories of employability: interpersonal, intrapersonal and career attributes. The research indicated that significant differences exist between gender, race and age groups with regard to employability. Male and female participants differed significantly with regard to entrepreneurial orientation, proactivity and career resilience. The various race groups differed considerably regarding cultural competence and sociability of individuals. Participants older than 50 years scored the highest on self-efficacy. Conclusion and implications: The findings of this research could ensure that previously disadvantaged individuals are not further marginalised because of a lack of employability attributes and that the required employability attributes can be cultivated to ensure advancement and success in the work place.

Particle physicist Martin Lewis Perl was recognized worldwide for his discovery of the τ (tau) lepton. For that achievement he received the 1982 Wolf Prize and shared the 1995 Nobel Prize in Physics. He was also a Fellow of the American Physical Society and a member of the National Academy of Sciences (elected 1981). Martin's distinctive approach to scientific investigation had its origins in his upbringing and in the influence of I. I. Rabi, his graduate advisor at Columbia University. After coming to Stanford University in 1963, Martin sought to understand why there should be two and only two families of leptons: the electron and its associated neutrino; and the muon and the muon neutrino. His discovery of the τ provided evidence for a third family of fundamental leptons. The bottom quark was discovered shortly afterward at the Fermi National Accelerator Laboratory, providing evidence for a third family of quarks. Direct evidence for the τ neutrino came later, thereby completing the third lepton generation, while the discovery of the top quark in 1995 completed the third generation of quarks. These achievements established leptons and quarks as fundamental constituents of matter and, along with the fundamental forces, provided the experimental basis of the "Standard Model," our picture of how all matter is made up and how its components interact. Why there are three and only three families of leptons and quarks remains an unsolved mystery to this day.

Full Text Available In the second half of the 19th century, in Portugal, an elite of men of science and technology, who had previously contacted with the saint-simonianist ideology, led the implementation of the public works programme historically known as Fontismo (after its main promoter, Fontes Pereira de Melo. One of the members of that elite was engineer Manuel Afonso de Espregueira. In this paper we will write his biographical sketch, using Marcel Mauss’s concept of persona, reconfigured as scientific persona – created in particular for the biographical analysis of persons of science and technology. We will read on a varied array of primary sources, spread across sundry archives and libraries, in order to accompany the life path of Espregueira and characterize his academic, technical/professional and political course. In the end, we aim to illustrate the relevance of Espregueira’s career for the public works agenda of Fontismo and for the formation of the persona of the Portuguese engineer of the 19th century.

This invention concerns a process for fracturing underground formations and has as one object the mixing of viscous compositions. Through a borehole, a fluid is injected into the formation. This fluid contains a complex prepared by the reaction of an aliphatic quaternary ammonium compound with a water-soluble compound chosen from monosaccharides, disaccharides, trisaccharides, polysaccharides, and synthetic hydroxylated polymers with long chains. These complexes are formed at temperatures between 20/sup 0/ and 205/sup 0/C. The process also includes production of formation fluid into the borehole.

Memory formation and storage require long-lasting changes in memory-related neuronal circuits. Recent evidence indicates that DNA methylation may serve as a contributing mechanism in memory formation and storage. These emerging findings suggest a role for an epigenetic mechanism in learning and long-term memory maintenance and raise apparent conundrums and questions. For example, it is unclear how DNA methylation might be reversed during the formation of a memory, how changes in DNA methylation alter neuronal function to promote memory formation, and how DNA methylation patterns differ between neuronal structures to enable both consolidation and storage of memories. Here we evaluate the existing evidence supporting a role for DNA methylation in memory, discuss how DNA methylation may affect genetic and neuronal function to contribute to behavior, propose several future directions for the emerging subfield of neuroepigenetics, and begin to address some of the broader implications of this work.
Full Text Available Motivated by the idea of multiplexed model predictive control (MMPC, this paper introduces a new framework for unmanned aerial vehicles (UAVs formation flight and coordination. Formulated using MMPC approach, the whole centralized formation flight system is considered as a linear periodic system with control inputs of each UAV subsystem as its periodic inputs. Divided into decentralized subsystems, the whole formation flight system is guaranteed stable if proper terminal cost and terminal constraints are added to each decentralized MPC formulation of the UAV subsystem. The decentralized robust MPC formulation for each UAV subsystem with bounded input disturbances and model uncertainties is also presented. Furthermore, an obstacle avoidance control scheme for any shape and size of obstacles, including the nonapriorily known ones, is integrated under the unified MPC framework. The results from simulations demonstrate that the proposed framework can successfully achieve robust collision-free formation flights.

We present ASDF, the Adaptable Seismic Data Format, a modern and practical data format for all branches of seismology and beyond. The growing volume of freely available data coupled with ever expanding computational power opens avenues to tackle larger and more complex problems. Current bottlenecks include inefficient resource usage and insufficient data organization. Properly scaling a problem requires the resolution of both these challenges, and existing data formats are no longer up to the task. ASDF stores any number of synthetic, processed or unaltered waveforms in a single file. A key improvement compared to existing formats is the inclusion of comprehensive meta information, such as event or station information, in the same file. Additionally, it is also usable for any non-waveform data, for example, cross-correlations, adjoint sources or receiver functions. Last but not least, full provenance information can be stored alongside each item of data, thereby enhancing reproducibility and accountability. Any data set in our proposed format is self-describing and can be readily exchanged with others, facilitating collaboration. The utilization of the HDF5 container format grants efficient and parallel I/O operations, integrated compression algorithms and check sums to guard against data corruption. To not reinvent the wheel and to build upon past developments, we use existing standards like QuakeML, StationXML, W3C PROV and HDF5 wherever feasible. Usability and tool support are crucial for any new format to gain acceptance. We developed mature C/Fortran and Python based APIs coupling ASDF to the widely used SPECFEM3D_GLOBE and ObsPy toolkits.

This article examines nutrition labeling history as well as the findings of nine research studies of nutrition labeling formats. Nutrition labeling regulations were announced in 1973 and have been periodically amended since then. In response to requests from consumers and health care professionals for revision of the labeling system, the Food and Drug Administration initiated a three-phase plan for reform of nutrition labeling in 1990. President Bush signed the Nutrition Labeling and Education Act in November 1990. Literature analysis revealed that only nine studies with an experimental design have focused on nutrition labeling since 1971. Four were conducted before 1975, which was the year that nutrition labeling was officially implemented, two were conducted in 1980, and three were conducted after 1986. Only two of the nine studies supported the traditional label format mandated by the Code of Federal Regulations, and one study partially supported it. Four of the nine studies that evaluated graphic presentations of nutrition information found that consumer comprehension of nutrition information was improved with a graphic format for nutrition labeling: three studies supported the use of bar graphs and one study supported the use of a pie chart. Full disclosure (ie, complete nutrient and ingredient labeling) was preferred by consumers in two of the three studies that examined this variable. The third study supported three types of information disclosure dependent upon socioeconomic class. In those studies that tested graphics, a bar graph format was significantly preferred and showed better consumer comprehension than the traditional format.

Full Text Available The paper considers automation problems of the interface formation between a table and a relational database. The task description is formalized and the description of the existing approaches to formation of data representations on an example of widely widespread CASE-tools is submitted. The definition of intermediate data representation as a ”join table” is offered, which is used for maintenance of correctness of data representation formation, and also is necessary for direct and inverse data transformations. On the basis of lossless join property and realized dependencies, the concept and a way of context formation of the application and restrictions is introduced. The considered material is further used for constructing an inverse data transformation from tabular presentation into a relational one. On the basis of relationships properties on a database scheme, the partial order on the relations is established, and the restriction of acyclic databases schemes is introduced. The received results are further used at the analysis of principles of formation of inverse data transformation, and the basic details of such a transformation algorithm are considered.

An educator's view would be that formative assessment has an important role in the learning process. This study was carried out to obtain a student perspective of the place of formative assessment in the curriculum. Final-year medical students at Royal Prince Alfred Hospital took part in four teaching sessions, each structured to integrate teaching with assessment. Three assessment methods were used; the group objective structured clinical examination (G-OSCE), structured short answer (SSA) questions and a pre/post-test multiple choice questionnaire (MCQ). Teaching sessions were conducted on the subject areas of traumatology, the 'acute abdomen', arterial disorders and cancer. Fifty-five students, representing 83% of those who took part in the programme, responded to a questionnaire where they were asked to rate (on a 5-point Likert scale) their response to general questions about formative assessment and 13 specific questions concerning the comparative value of the three assessment modalities. Eighty-nine per cent of respondents felt that formative assessment should be incorporated into the teaching process. The SSA assessment was regarded as the preferred modality to reinforce previous teaching and test problem-solving skills. The MCQ was the least favoured assessment method. The effect size variable between the total scores for the SSA and MCQ was 0.64. The variable between G-OSCE and SSA/MCQ was 0.26 and 0.33 respectively. Formative assessment is a potentially powerful method to direct learning behaviour. Students should have input into the methods used.

Planetesimals are the precursors to planets, and understanding their formation is an essential step towards developing a complete theory of planet formation. For small solid particles (e.g., dust grains) to coagulate into planetesimals, however, requires that these particles grow beyond centimeter sizes; with traditional coagulation physics, this is very difficult. The streaming instability, which is a clumping process akin to the pile-up of cars in a traffic jam, generates sufficiently high solid densities that the mutual gravity between the clumped particles eventually causes their collapse towards planetesimal mass and size scales. Exploring this transition from dust grains to planetesimals is still in its infancy but is extremely important if we want to understand the basics of planet formation. Here, I present a series of high resolution, first principles numerical simulations of potoplanetary disk gas and dust to study the clumping of particles via the streaming instability and the subsequent collapse towards planetesimals. These simulations have been employed to characterize the planetesimal population as a function of radius in protoplanetary disks. The results of these simulations will be crucial for planet formation models to correctly explain the formation and configuration of solar systems.

We compare the evolutions of new markets in China for gas......-powered two-wheeled vehicles (G2WVs) based (initially) on closed-system proprietary architectures and for electric-powered two-wheeled vehicles (E2WVs) based on open-system modular architectures. We draw on this comparison to suggest ways in which the use of the two different kinds of architectures...... as the basis for new kinds of products may result in very different patterns and speeds of new market formation. We then suggest some key implications of the different dynamics of market formation associated with open-system modular architectures for both the competence-based strategic management (CBSM...
Cosmic strings have become increasingly popular candidates as seeds for the formation of structure in the universe. This scenario, remains a serious cosmogonical model despite close scrutiny. In constrast, magnetic monopoles and domain walls - relic topological defects as are cosmic strings - are disastrous for cosmology if they are left over from the early universe. The production of heavy cosmic strings is speculative, as it depends on the details of ultrahigh energy physics. Fortunately, speculation about cosmic strings is not entirely idle because, if they exist and are heavy enough to seed galaxy formation, cosmic strings can be detected astronomically. Failure to detect cosmic strings would impose some constraints on grand unified theories (GUTs); their discovery would have exciting consequences for high energy physics and cosmology. This article reviews the basic physics of nonsuperconducting cosmic strings, highlighting the field theory aspects, and provides a progress report on calculations of structure formation with cosmic strings
Commercially successful programme ideas are often imitated or adapted. Television formats, in particular, are routinely copied. Starting from radio formats in the 1950s to game shows and reality programme formats of today, producers have accused others of “stealing”. Although formats constitute one of the most important exports for British TV producers, there is still no certainty about the legal protection of TV formats from copycat versions. Since TV formats fail to fall neatly within the d...

During the treatment of dental caries that has not penetrated the tooth pulp, maintenance of as much unaffected dentine as possible is a major goal during the physical removal of decayed mineral. Damage to dentine leads to release of fossilized factors (transforming growth factor-β [TGF-β] and bone morphogenic protein [BMP]) in the dentine that are believed to stimulate odontoblasts to secrete new "tertiary" dentine (reactionary dentine). This is formed on the pulpal surface of existing dentine and rethickens the dentine. We have previously shown that activation of Wnt/β-catenin signaling is pivotal for tooth repair in exposed pulp injury, and the pathway can be activated by small-molecule GSK-3 antagonists, resulting in enhanced reparative dentine formation. Here, we use a nonexposed pulp injury model to investigate the mechanisms of reactionary dentine formation in vivo, using small molecules to modulate the Wnt/β-catenin, TGF-β, and BMP pathways. We found that a local increase of Wnt activation at the injury site enhances reactionary dentine secretion. In addition, inhibition of TGF-β, BMP, or Wnt pathways does not impede reactionary dentine formation, although inhibition of TGF-β and/or BMP signaling does result in more disorganized, nontubular reactionary dentine. This suggests that Wnt/β-catenin signaling plays no major role in the formation of reactionary dentine, but in common with reparative dentine formation, exogenous elevation of Wnt/β-catenin signaling can enhance tertiary dentine formation. Release of latent TGF-β or BMPs from dentine is not required for the deposition of mineral to form reactionary dentine but does play a role in its organization.

Luciano Mendes de Almeida (1930-2006, bispo-auxiliar de São Paulo e arcebispo de Mariana, secretário e presidente da CNBB além de vice-presidente do CELAM, à sua própria trajetória biográfica. Verifica-se que, se cotejada com balizas culturais contemporâneas, tal configuração de si porta contornos aparentemente paradoxais: ao invés de fortalecer uma identidade pessoal, ela pressupõe uma dinâmica antropológico-religiosa de autoesvaziamento, concomitante a uma atuação mediadora em prol de relações ternárias entre Deus, os sujeitos e si mesmo, processo denominado por D. Luciano como “interiorização da figura Jesus Cristo”. Com o suporte teórico provindo da semiótica e da história religiosa, tal interiorização é aqui compreendida como um programa narrativo específico, que adquiriu formas singulares ao longo dos séculos, com destaque à espiritualidade inaciana, mas preservando sua concepção como um agir, pela fé, em nome da competência atribuída a um Outro. Sugere-se ainda que, na atualidade, a interiorização possa ser aproximada do relato de testemunho, face ao engajamento ético por ela suscitado, que reconfigura o sujeito no compartilhar de experiências vividas e postas em discurso.

Radioactive waste disposal into geological formation is based on the capacity of rocks to confine radioactivity for a long period of time. Radionuclide migration from the repository to the environment depends on different mechanisms and phenomena whose two main ones are groundwater flow and the retention and ion-exchange property of rocks. Many studies are underway presently in EEC countries concerning hydrodynamic characteristics of deep geological formations as well as in radionuclide retention capacity and modelling. Important results have already been achieved which show the complexity of some phenomena and further studies shall principally be developed taking into account real conditions of the repository and its environment

Debris-covered glaciers are prone to the formation of a number of supraglacial geomorphological features, and generally speaking, their upper surfaces are far from level surfaces. Some of these features are due to radiation screening or enhancing properties of the debris cover, but theoretical explanations of the consequent surface forms are in their infancy. In this paper we consider a theoretical model for the formation of "ice sails", which are regularly spaced bare ice features which are found on debris-covered glaciers in the Karakoram.

The formation of galaxies is one of the greatest puzzles in astronomy, the solution is shrouded in the depths of space and time, but has profound implications for the universe we observe today. The book discusses the beginnings of the process from cosmological observations and calculations, considers the broad features of galaxies that we need to explain and what we know of their later history. The author compares the competing theories for galaxy formation and considers the progress expected from new generations of powerful telescopes both on earth and in space. In this second edition the author has retained the observationally-based approach of the first edition, a feature which was particularly well-reviewed: Writing in Nature, Carlton Baugh noted in February 2003 that “It is refreshing, in a market dominated by theorists, to come across a book on galaxy formation written from an observational perspective. The Road to Galaxy Formation should prove to be a handy primer on observations for graduate student...

This paper presents a model of partnership formation. A number of agents want to conduct some business or other activities. Agents may act alone or seek a partner for cooperation and need in the latter case to consider with whom to cooperate and how to share the profit in a collaborative and
Is it true that all formative influence is unethical, and that we ought to avoid influencing children (and indeed anyone at all)? There are more or less defensible versions of this doctrine, and we shall follow some of the strands of argument that lead to this conclusion. It seems that in maintaining that all influence is immoral, one commits…

Stationary luminescence spectra of disordered solid solutions can be accounted by the model of localized excitons. Detailed analysis of the long time decay kinetics of luminescence shows that exciton formation in these systems is in great extent due to the bimolecular reaction of separated carrie...

This thesis presents mantle convection numerical simulations of supercontinent formation. Approximately 300 million years ago, through the large-scale subduction of oceanic sea floor, continental material amalgamated to form the supercontinent Pangea. For 100 million years after its formation, Pangea remained relatively stationary, and subduction of oceanic material featured on its margins. The present-day location of the continents is due to the rifting apart of Pangea, with supercontinent dispersal being characterized by increased volcanic activity linked to the generation of deep mantle plumes. The work presented here investigates the thermal evolution of mantle dynamics (e.g., mantle temperatures and sub-continental plumes) following the formation of a supercontinent. Specifically, continental insulation and continental margin subduction are analyzed. Continental material, as compared to oceanic material, inhibits heat flow from the mantle. Previous numerical simulations have shown that the formation of a stationary supercontinent would elevate sub-continental mantle temperatures due to the effect of continental insulation, leading to the break-up of the continent. By modelling a vigorously convecting mantle that features thermally and mechanically distinct continental and oceanic plates, this study shows the effect of continental insulation on the mantle to be minimal. However, the formation of a supercontinent results in sub-continental plume formation due to the re-positioning of subduction zones to the margins of the continent. Accordingly, it is demonstrated that continental insulation is not a significant factor in producing sub-supercontinent plumes but that subduction patterns control the location and timing of upwelling formation. A theme throughout the thesis is an inquiry into why geodynamic studies would produce different results. Mantle viscosity, Rayleigh number, continental size, continental insulation, and oceanic plate boundary evolution are

The compact multi-transiting planet systems discovered by Kepler challenge planet formation theories. Formation in situ from disks with radial mass surface density, Σ, profiles similar to the minimum mass solar nebula but boosted in normalization by factors ≳ 10 has been suggested. We propose that a more natural way to create these planets in the inner disk is formation sequentially from the inside-out via creation of successive gravitationally unstable rings fed from a continuous stream of small (∼cm-m size) 'pebbles', drifting inward via gas drag. Pebbles collect at the pressure maximum associated with the transition from a magnetorotational instability (MRI)-inactive ('dead zone') region to an inner MRI-active zone. A pebble ring builds up until it either becomes gravitationally unstable to form an ∼1 M ⊕ planet directly or induces gradual planet formation via core accretion. The planet may undergo Type I migration into the active region, allowing a new pebble ring and planet to form behind it. Alternatively, if migration is inefficient, the planet may continue to accrete from the disk until it becomes massive enough to isolate itself from the accretion flow. A variety of densities may result depending on the relative importance of residual gas accretion as the planet approaches its isolation mass. The process can repeat with a new pebble ring gathering at the new pressure maximum associated with the retreating dead-zone boundary. Our simple analytical model for this scenario of inside-out planet formation yields planetary masses, relative mass scalings with orbital radius, and minimum orbital separations consistent with those seen by Kepler. It provides an explanation of how massive planets can form with tightly packed and well-aligned system architectures, starting from typical protoplanetary disk properties.

There has been great concern about dioxins-polychlorinated dibenzo dioxins (PCDDs), polychlorinated dibenzo furans (PCDFs), and polychlorinated biphenyls (PCBs)-causing contamination in the environment because the adverse effects of these chemicals on human health have been known for many years. Possible dioxin-contamination has received much attention recently not only by environmental scientists but also by the public, because dioxins are known to be formed during the combustion of industrial and domestic wastes and to escape into the environment via exhaust gases from incinerators. Consequently, there is a pressing need to investigate the formation mechanisms or reaction pathways of these chlorinated chemicals to be able to devise ways to reduce their environmental contamination. A well-controlled small-scale incinerator was used for the experiments in the core references of this review. These articles report the investigation of dioxin formation from the combustion of various waste-simulated samples, including different kinds of paper, various kinds of wood, fallen leaves, food samples, polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC), polyvinylidene chloride, polyethylene tetraphthalate (PET), and various kinds of plastic products. These samples were also incinerated with inorganic chlorides (NaCl, KCl, CuCI2, MgCl2, MnCl2, FeCl2, CoCl2, fly ash, and seawater) or organic chlorides (PVC, chlordane, and pentachlorophenol) to investigate the role of chlorine content and/or the presence of different metals in dioxin formation. Some samples, such as newspapers, were burned after they were impregnated with NaCl or PVC, as well as being cocombusted with chlorides. The roles of incineration conditions, including chamber temperatures, O2 concentrations, and CO concentrations, in dioxin formation were also investigated. Dioxins (PCDDs, PCDFs, and coplanar-PCBs) formed in the exhaust gases from a controlled small-scale incinerator, where experimental waste

We study the effect of adaptivity on a social model of opinion dynamics and consensus formation. We analyse how the adaptivity of the network of contacts between agents to the underlying social dynamics affects the size and topological properties of groups and the convergence time to the stable final state. We find that, while on static networks these properties are determined by percolation phenomena, on adaptive networks the rewiring process leads to different behaviors: adaptive rewiring fosters group formation by enhancing communication between agents of similar opinion, though it also makes possible the division of clusters. We show how the convergence time is determined by the characteristic time of link rearrangement. We finally investigate how the adaptivity yields nontrivial correlations between the internal topology and the size of the groups of agreeing agents

The principles and technical aspects of track formation in insulating solids are first described. The characteristics of dialectic track detection are discussed from the technical point of view: the nature of the detectors, the chemical treatment, the sensitivity and the environmental conditions of use. The applications are reviewed. The principle of each type of applied research is described and then the applications are listed. When used as a detector, nuclear tracks can provide valuable information in a number of fields: element content determination and wrapping, imaging, radiation dosimetry, environmental studies, technological uses and miscellaneous other applications. The track-formation process can also be used for making well-defined holes; this method allows other applications which are also described. Finally, some possible future applications are mentioned.

A preliminary survey was conducted of the thermonuclear energy release expected during star formation. The destruction of primordial deuterium provides substantial amounts of energy at surprisingly low temperatures, and must be considered in any meaningful treatment of star formation carried to stages in which the internal temperature exceeds a few hundred thousand degrees. Significant energy generation from consumption of initial lithium requires higher temperatures, of the order of a few million degrees. Depletion of primordial beryllium and boron may never provide an important energy source. The approach to equilibrium of the carbon--nitrogen cycle is dominant at temperatures approaching those characteristic of the central regions of main sequence stars. The present calculation should serve as a useful guide in choosing those nuclear processes to be included in a more detailed study. 8 figures, 2 tables
Network coevolution, the process of network topology evolution in feedback with dynamical processes over the network nodes, is a common feature of many engineered and natural networks. In such settings, the change in network topology occurs at a comparable time scale to nodal dynamics. Coevolutionary modeling offers the possibility to better understand how and why network structures emerge. For example, social networks can exhibit a variety of structures, ranging from almost uniform to scale-free degree distributions. While current models of network formation can reproduce these structures, coevolutionary modeling can offer a better understanding of the underlying dynamics. This paper presents an overview of recent work on coevolutionary models of network formation, with an emphasis on the following three settings: (i) dynamic flow of benefits and costs, (ii) transient link establishment costs, and (iii) latent preferential attachment.

Quasar mode feedback is thought to be a crucial ingredient in galaxy formation for luminous merging and star-bursting systems at high redshift. The energy from the active nucleus should cause significant gas outflows, reducing the available free gas reservoir for future star formation. It is currently unknown which observational state best corresponds to the stage at which this "blowout" should occur. We intend to test one possible source population for this transition phase, by studying the molecular gas content in a small, statistically complete sample of 3 K-band selected reddened quasars from the AUS survey. All lie in the redshift range 2

An incompetent formation is consolidated and left permeable by first injecting a solidifiable liquid resin, and following this by an organic liquid to set the resin. The liquid resin used may be 3 (glycidyloxy) propyl trimethoxysilane in sufficient concentration to considerably increase the compressive strength of the consolidated zone. The silane may be used in a ratio of between 0.5 and 5% of the total volume of the liquid resin. The liquid resin used may be a phenol-formaldehyde condensation product dispersed in an aliphatic alcohol with from 1 to 4 carbon atoms. The liquid resin used may be an epoxy containing a hardener. The resin may be displaced into the formation by a liquid hydrocarbon. (5 claims)

Full Text Available The article examines the potentials of the concept of othering to describe identity formation among ethnic minorities. First, it outlines the history of the concept, its contemporary use, as well as some criticisms. Then it is argued that young ethnic minority men in Denmark are subject to intersectional othering, which contains elements of exoticist fascination of the other. On the basis of ethnographic material, it is analysed how young marginalized ethnic minority men react to othering. Two types of reactions are illustrated: 1 capitalization on being positioned as the other, and 2 refusing to occupy the position of the other by disidentification and claims to normality. Finally, it is argued that the concept of othering is well suited for understanding the power structures as well as the historic symbolic meanings conditioning such identity formation, but problematic in terms of agency.
