    The main objective of the ExoMars 2020 mission is to search for signs of past and/or present life on Mars. Toward this goal, a rover was designed to investigate the shallow subsurface which is the most likely place where signs of life may be preserved, beneath the hostile surface of Mars. The rover of the ExoMars 2020 mission has on board a polarimetric ground penetrating radar called WISDOM (Water Ice Subsurface Deposits Observation on Mars). Thanks to its large frequency bandwidth of 2.5 GHz, WISDOM is able to probe down to a depth of approximately 3 m on sedimentary rock with a vertical resolution of a few centimeters.The main scientific objectives of WISDOM are to characterize the shallow subsurface of Mars, to help understand the local geological context and to identify the most promising location for drilling. The WISDOM team is currently working on the preparation of the scientific return of the ExoMars 2020 mission. In particular, tools are developed to interpret WISDOM experimental data and, more specifically, to extract information from the radar signatures of expected buried reflectors. Insights into the composition of the ground (through the retrieval of its permittivity) and the geological context of the site can be inferred from the radar signature of buried rocks since the shape and the density of rocks in the subsurface is related to the geological processes that have shaped and placed them there (impact, fluvial processes, volcanism). This paper presents results obtained by automatic detection of structures of interest on a radargram, especially radar signature of buried rocks. The algorithm we developed uses a neural network to identify the position of buried rocks/blocs and then a Hough transform to characterize each signature and to estimate the local permittivity of the medium. Firstly, we will test the performances of the algorithm on simulated data constructed with a 3D FDTD code. This code allows us to simulate radar operation in realistic

    Full Text Available Objective Measurement of Wisdom within a short period of time is vital for both the public interest (e.g., understanding a presidential election and research (e.g., testing factors that facilitate wisdom development. A measurement of emotion associated with wisdom would be especially informative; therefore, a novel Thin-Slice measurement of wisdom was developed based on the Berlin Paradigm. For about 2 min, participants imagined the lens of a camera as the eyes of their friend/teacher whom they advised about a life dilemma. Verbal response and facial expression were both recorded by a camera: verbal responses were then rated on both the Berlin Wisdom criteria and newly developed Chinese wisdom criteria; facial expressions were analyzed by the software iMotion FACET module. Results showed acceptable inter-rater and inter-item reliability for this novel paradigm. Moreover, both wisdom ratings were not significantly correlated with Social desirability, and the Berlin wisdom rating was significantly negatively correlated with Neuroticism; feeling of surprise was significantly positively correlated with both wisdom criteria ratings. Our results provide the first evidence of this Thin-slice Wisdom Paradigm’s reliability, its immunity to social desirability, and its validity for assessing candidates’ wisdom within a short timeframe. Although still awaiting further development, this novel Paradigm contributes to an emerging Universal Wisdom Paradigm applicable across cultures.

    Full Text Available In psychology, wisdom gradually received more and more interest form researchers. The first who have directed their attention to this area were the Greek philosophers, but gradually theoretical models were developed based on empirical data and components that explain the development of wisdom. In this paper, we used Ardelt's approach, which takes into account both the eastern and western approaches regarding wisdom. Within a sample of students (N = 100, mean age = 24, SD = 6.44, wisdom was investigated in relation to several phenomena that could be involved in the development of wisdom and wisdom processes. Thus, wisdom is studied in relation to general metacognition, moral metacognition, cognitive empathy, emotional empathy, irrationality and cognitive flexibility. The results were found to be in accordance with the hypothesis of affective empathy, identifying a significant positive relationship between the two variables. One must consider that the rest of the correlations were negative and significant, thus drawing attention to other possible factors that might be important in describing wisdom. Variables evaluated were found to explain the variance of wisdom.

    2017-03-01

    Full Text Available Purpose – A fundamental problem for intelligent manufacturing is to equip the agents with the ability to automatically make judgments and decisions. This paper aims to introduce the basic principle for intelligent crowds in an attempt to show that crowd wisdom could help in making accurate judgments and proper decisions. This further shows the positive effects that crowd wisdom could bring to the entire manufacturing process. Design/methodology/approach – Efforts to support the critical role of crowd wisdom in intelligent manufacturing involve theoretical explanation, including a discussion of several prevailing concepts, such as consumer-to-business (C2B, crowdfunding and an interpretation of the contemporary Big Data mania. In addition, an empirical study with three business cases was conducted to prove the conclusion that our ideas could well explain the current business phenomena and guide the future of manufacturing. Findings – This paper shows that crowd wisdom could help make accurate judgments and proper decisions. It further shows the positive effects that crowd wisdom could bring to the entire manufacturing process. Originality/value – The paper highlights the importance of crowd wisdom in manufacturing with sufficient theoretical and empirical analysis, potentially providing a guideline for future industry.

  10. Researching Practice Wisdom in Social Work

    Full Text Available Researching practice wisdom in social work Social workers, as skilled helpers who make professional decisions using intuitive actions rather than by following defined rules, deserve better recognition for their practice wisdom. However, since there is a tendency amongst practitioners who adhere to the evidence-based paradigm to disregard practitioners’ knowledge, empirical research on practice wisdom in social work needs to be encouraged. The author argues that the lack of a sound methodology hinders the development of such an invaluable asset for practitioners. It is suggested that a heuristic paradigm that embraces the concepts of tacit knowing, intuition and indwelling will provide a way forward towards recognizing the importance of social workers’ practice wisdom.

  11. The Relationship between Mental and Somatic Practices and Wisdom.

    Directory of Open Access Journals (Sweden)

    Patrick B Williams

    Full Text Available In this study we sought to explore how experience with specific mental and somatic practices is associated with wisdom, using self-report measures of experience and wisdom. We administered standard surveys to measure wisdom and experience among four groups of practitioners of mental and somatic practices, namely, meditators, practitioners of the Alexander Technique, practitioners of the Feldenkrais Method, and classical ballet dancers. We additionally administered surveys of trait anxiety and empathy to all participants to explore possible mediating relationships of experience and wisdom by characteristics thought to be components of wisdom. Wisdom was higher on average among meditation practitioners, and lowest among ballet dancers, and this difference held when controlling for differences in age between practices, supporting the view that meditation is linked to wisdom and that ballet is not. However, we found that increased experience with meditation and ballet were both positively associated with wisdom, and that lowered trait anxiety mediated this positive association among meditation practitioners, and, non-significantly, among ballet dancers. These results suggest that not all practices that are purported to affect mental processing are related to wisdom to the same degree and different kinds of experience appear to relate to wisdom in different ways, suggesting different mechanisms that might underlie the development of wisdom with experience.

  12. Psalm 26 and Proverbs: Tracing wisdom themes

    Directory of Open Access Journals (Sweden)

    Annette Potgieter

    2014-01-01

    Full Text Available The discernment of Psalm 26 as a cultic psalm has prevented noticing vital connections with wisdom literature. These connections with Proverbs and other known wisdom psalms provide clues for the composition of Psalm 26 to be set in the post-exilic period. The way in which wisdom literature is used conveys the religious ethos and daily life of a community. The fact that the wisdom character of Psalm 26 has been overlooked can be viewed as one of the main reasons why Psalm 26 has been interpreted solely in a cultic setting. The sapiential influence of this psalm has been confused to only reflect the cultic aspects. The psalmist wants to live a life according to wisdom as he seeks the rewards of being close to Yahweh.

    Full Text Available En Russie, chaque année, les déversements de pétrole représentent un cinquième de la production totale. Les plus importants se produisent dans le domaine périglaciaire où le milieu naturel est d’une extrême fragilité. Les pipelines sont soumis à de rudes conditions notamment à la corrosion et aux processus cryogéniques. Le risque de rupture augmente en conséquence. La surveillance des déversements d’hydrocarbures, contrainte par l’immensité et la fréquente inaccessibilité du réseau de pipelines, peut être réalisée par le recours à la télédétection. L’objectif de ce travail est de fournir, à travers l’exemple de la catastrophe d’Usinsk (Rép. de Komi survenue en 1994, des outils d’analyse des images radar. Outre leur capacité à s’affranchir du couvert nuageux, les capteurs radar apportent des informations complémentaires à celles fournies par des capteurs optiques. L’exploitation thématique de ces images est rendue difficile par un certain nombre de facteurs perturbateurs tels que les caractéristiques propres du capteur, la direction de visée, la topographie et le phénomène de chatoiement (speckle. Le travail présenté montre lele prépondérant joué par ces corrections qui permettent de disposer de données quantitatives comparables d’une date à une autre. La méthode mise au point ici pour le suivi temporel de l’épanchement de pétrole d’Usinsk à partir de trois images radar, est discutée notamment dans ses limites et son aspect opérationnel possible.

    Wisdom is a complex phenomenon: it finds its home primarily but not exclusively in theology, philosophy, psychology, education--that is, in the humanities--and in life itself. In a paradoxical manner, wisdom finds its home in the world of the unanswerable, where there are no empirical proofs and no obvious answers. Wisdom actually finds its place…

  18. Job and Ecclesiastes as (postmodern? wisdom in revolt

    Directory of Open Access Journals (Sweden)

    Leon A. Roper

    2013-09-01

    Full Text Available This article will be concerned with the question whether the books of Job and Ecclesiastes can be viewed as (postmodern wisdom in revolt or not. Three questions underlie this title: firstly, are the books of Job and Ecclesiastes wisdom books? Secondly, if so, is their wisdom revolutionary in nature? And thirdly, are there any similarities between the thoughts of Job and Ecclesiastes on the one hand and that of postmodern thinkers on the other hand? It will be argued that there are various similarities to be cited between the ideas of the ancient wisdom writers of Job and Ecclesiastes and more recent postmodern thinkers. This does not, however, necessarily justify a postmodern tag for the books of Job and Ecclesiastes, but points to a similarity in thought development between the ancient societies of Job and Ecclesiastes and the present-day societies. Such similarities are viewed as a clear indication of the meaningful role which Old Testament wisdom, or wisdom in revolt for that matter, can play in current intellectual and theological debates.

  19. Wisdom teeth: mankind's future third vice-teeth?

    The third molar teeth (wisdom teeth) represent the last eruption of the teeth in the human dentition. Throughout evolution, the mandible has had a tendency to decrease in size; the third molar teeth are often impacted, resulting in incomplete tooth eruption that often causes clinical pericoronitis, dental caries, and pericemental abscess. Therefore, the wisdom teeth are often extracted. Moreover, wisdom teeth are often removed for clinical orthodontic treatment. On the other hand, tooth loss due to periodontal disease, dental caries, trauma, or a variety of genetic disorders continues to affect people's lives. Autologous tissues for dental tissue regeneration that could replace lost teeth could provide a vital alternative to currently available clinical treatments. To pursue this goal, we hypothesize that human third molar tooth buds can be obtained during development. Human wisdom tooth germination tissue could then be placed into an embryonic stem cell bank for storage. When the donor's other teeth are missing, embryonic stem cell and tissue engineering technologies, will permit the restoration of the missing teeth. Therefore wisdom teeth will be mankind's future third vice-teeth.

    2013-01-01

    Wisdom is a field of growing interest both inside and outside academic psychology, and researchers are increasingly interested in using measures of wisdom in their work. However, wisdom is a highly complex construct, and its various operationalizations are based on quite different definitions. Which measure a researcher chooses for a particular research project may have a strong influence on the results. This study compares four well-established measures of wisdom—the Self-Assessed Wisdom Scale (Webster, 2003, 2007), the Three-Dimensional Wisdom Scale (Ardelt, 2003), the Adult Self-Transcendence Inventory (Levenson et al., 2005), and the Berlin Wisdom Paradigm (Baltes and Smith, 1990; Baltes and Staudinger, 2000)—with respect to content, reliability, factorial structure, and construct validity (relationships to wisdom nomination, interview-based wisdom ratings, and correlates of wisdom). The sample consisted of 47 wisdom nominees and 123 control participants. While none of the measures performed “better” than the others by absolute standards, recommendations are given for researchers to select the most suitable measure for their substantive interests. In addition, a “Brief Wisdom Screening Scale” is introduced that contains those 20 items from the three self-report scales that were most highly correlated with the common factor across the scales.

    Ancient wisdom informs traditional knowledges that guide Indigenous communities on how to interact with the world. These knowledges and the ancient wisdom have been the life-giving forces that have prevented the complete genocide of Indigenous peoples, and is also the wisdom that is rejuvenating ancient ways that will take the world into a future that embraces the seventh generation philosophy.. Western scientists and agency representatives are learning from the work and wisdom of Native Americans. This presentation will share the ways in which the representatives of two Tribes along the coast of Louisiana have been helping to educate and apply their work with Western scientists.

    Science.gov (United States)

    Pesut, Daniel J; Thompson, Sarah A

    The purpose of this article is to discuss insights derived from adult cognitive developmental theories and relate the insights to vertical leadership development in academic nursing contexts. Equipped with developmental understanding, academic leaders are in a better position to support the vertical leadership development of one's self, faculty, peers, and colleagues. From a cognitive developmental perspective, the authors' reason as leaders develop, grow, and evolve, sense making becomes more sophisticated and nuanced resulting in the development of wisdom. Leadership wisdom is a function of horizontal (acquisition of information, skills, and competencies) and vertical development (the development of more complex and sophisticated ways of thinking). Ways to enhance vertical development, and sense making to cultivate wisdom are discussed. Principles and practices that promote vertical development in self and others deepens performance expectations of those in the academy and supports personal professional development and organizational success.

    2016-07-01

    Full Text Available Wisdom is a unique personal attribute, mostly discussed in humanistic disciplines. Over the course of the last 30 years, the concept of wisdom has found a place in the psychological literature as well. Yet we still do not have a clear definition of it. Hence the main purpose of this article is to provide an overview of definitions of wisdom. Those proposed in the recent past can be categorized into four groupings: firstly, wisdom can be defined as a composite of competences or personality factors; secondly, it can be identified with that which counts as a positive outcome in respect of a person’s psychosocial development; thirdly, it can be regarded as a system of knowledge about the meaning and conduct of life; fourthly, it can be defined as a process emerging in real-life contexts. Finally, a very large majority of authors assume that wisdom depends on one’s having an unusually well-integrated personality structure.

    2018-02-07

    This study examined the development of wisdom within the context of difficult life events (DLEs), and the importance of individuals and their social environments in this process of growth. Social support has long been studied in adulthood, yet less is known about the ways social transactions can promote wisdom. Semi-structured interviews were conducted with men (n = 14) and women (n = 36), ages 56-91 years (M = 71.71; SD = 8.8) who described a DLE and how they coped with it. The analysis was guided by constructivist grounded theory. DLEs included those from childhood through later life. When personal meaning was disrupted by adversity, the social environment played a key role in facilitating new perspectives that corresponded with aspects of wisdom: self-knowledge, compassion, comfort with uncertainty, and accepting complexity. Wisdom is often studied as an individual characteristic, but this study highlighted the relevance of a social ecological perspective to understanding how wisdom development is also facilitated through social transactions. © The Author(s) 2018.

  11. Faith and wisdom in science

    CERN Document Server

    McLeish, Tom

    2014-01-01

    "Do you have wisdom to count the clouds?" asks the voice of God from the whirlwind in the stunningly beautiful catalogue of nature-questions from the Old Testament Book of Job. Tom McLeish takes a scientist's reading of this ancient text as a centrepiece to make the case for science as a deeply human and ancient activity, embedded in some of the oldest stories told about human desire to understand the natural world. Drawing on stories from the modern science of chaos and uncertainty alongside medieval, patristic, classical and Biblical sources, Faith and Wisdom in Science challenges much of the current 'science and religion' debate as operating with the wrong assumptions and in the wrong space. Its narrative approach develops a natural critique of the cultural separation of sciences and humanities, suggesting an approach to science, or in its more ancient form natural philosophy - the 'love of wisdom of natural things' - that can draw on theological and cultural roots. Following the theme of pain in human con...

  12. "Gratitude is with me all the time": how gratitude relates to wisdom.

    Science.gov (United States)

    König, Susanne; Glück, Judith

    2014-09-01

    This study investigated the relationship of gratitude to wisdom. Both constructs are conceptually related to self-reflectivity, but they differ in their emphasis on extrapersonal resources. Previous wisdom research has focused mainly on intrapersonal capacities. In Study 1, 47 wisdom nominees and 47 control participants were interviewed about their most difficult and best life event and filled out a questionnaire on sources of gratitude. Study 2 was a quantitative study (N = 443) of the relationship between a wisdom scale and scale measures and individual sources of gratitude. Significantly more wisdom nominees expressed feelings of gratitude spontaneously in their interview. Wisdom nominees reported gratitude for their life in general, religion, and partner more often than control participants. In Study 2, wisdom was related to all gratitude scales and to similar sources of gratitude as in Study 1. Both studies found gender differences in gratitude but not wisdom. Two important implications of these findings are that wisdom entails an appreciation of life and its experiences, especially the growth opportunities that may result from negative events, and that there may be substantial differences between male and female pathways to wisdom. © The Author 2013.

    2013-12-01

    With increasing longevity and a growing focus on successful aging, there has been a recent growth of research designed to operationalize and assess wisdom. We aimed to (1) investigate the degree of overlap among empirical definitions of wisdom, (2) identify the most commonly cited wisdom subcomponents, (3) examine the psychometric properties of existing assessment instruments, and (4) investigate whether certain assessment procedures work particularly well in tapping the essence of subcomponents of the various empirical definitions. We searched PsychINFO-indexed articles published through May 2012 and their bibliographies. Studies were included if they were published in a peer-reviewed journal and (1) proposed a definition of wisdom or (2) discussed the development or validation of an instrument designed to assess wisdom. Thirty-one articles met inclusion criteria. Despite variability among the 24 reviewed definitions, there was significant overlap. Commonly cited subcomponents of wisdom included knowledge of life, prosocial values, self-understanding, acknowledgment of uncertainty, emotional homeostasis, tolerance, openness, spirituality, and sense of humor. Published reports describing the psychometric properties of nine instruments varied in comprehensiveness but most measures were examined for selected types of reliability and validity, which were generally acceptable. Given limitations of self-report procedures, an approach integrating multiple indices (e.g., self-report and performance-based measures) may better capture wisdom. Significant progress in the empirical study of wisdom has occurred over the past four decades; however, much needs to be done. Future studies with larger, more diverse samples are needed to determine the generalizability, usefulness, and clinical applicability of these definitions and assessment instruments. Such work will have relevance for the fields of geriatrics, psychiatry, psychology, sociology, education, and public health

  14. WISDOM VALUESIN THE BANJARESE PROVERBS

    2015-09-01

    Full Text Available This study is aimed to reveal parts of Banjarese proverbs which contain wisdom values, to find kinds of wisdom values represented through the Banjarese proverbs, and to reveal social contexts influencing the producing and interpreting process of the proverbs. The data of this study are gathered and selected from several literatures of Banjarese which are then analyzed using critical linguistics.  The results of this study show that the parts which contain the wisdom values of the Banjarese people are the clues of interpretation. The wisdom values are also related to the good and the bad behaviours of Banjarese people. It is also found that Islam, as the religion followed by the majority of the Banjarese people, influences the Banjarese culture and Banjarese proverbs. Studi ini bertujuan untuk mencari tahu bagian mana saja dari peribahasa bahasa Banjar yang mengandung nilai kerarifan, menemukan bentuk nilai kearifan didalamnya, dan mengetahui apakah terdapat suatu konteks social yang mempengaruhi proses pembentukan dan penginterpetasian peribahasa itu sendiri. Data dalam studi ini dirangkum dari beberapa literatur yang ditulis oleh orang Banjar sendiri yang dipilih dengan alasan hanya literatur tersebut lah yang tersedia pada waktu studi ini dibuat. Data tersebut kemudian dianalisa dengan metode linguistic kritis. Studi ini menunjukkan bagian dari peribahasa Banjar yang cenderung mengandung nilai kearifan adalah penanda interpretasi. Hasil studi ini juga menunjukkan nilai kearifan dalam peribahasa Banjar terkait dengan sikap yang tidak patut ditiru dan sikap yang pantas untuk diikuti. Dan diasumsikan juga bahwa agama islam, yang terhitung sebagai agama yang dipeluk mayoritas penduduk Banjar, ternyata memiliki pengaruh terhadap kebudayaan dan peribahasa Banjar.

  15. We-ness and the Cultivation of Wisdom in Couple Therapy.

    Wisdom has played a key role in the attempt to understand the positive nature of human behavior since the time of Aristotle. In the past decade, psychology and related fields have experienced an expanding interest in the empirical and theoretical pursuit of wisdom. The relational dimension of wisdom has received less attention, although it may be viewed as embedded in the practice of all couple therapists. This article integrates previous work on resilience and positive functioning in committed partnerships and proposes relational wisdom to be a master virtue of relationship development, one that can be cultivated across the lifespan of the partnership. The aspects of relational wisdom such as self-reflection, attunement to self and other, balancing conflicting partner aims, the interpretation of rules and principles in light of the uniqueness of each situation and the capacity to learn from experience point to couples therapy as an ideal context for such skill building. Wisdom is built through dialog and the resulting individual and couple stories can serve as touchstones to what is most precious and vital in the relationship as well as guides for action through challenges and conflict. A clinical case is described to illustrate selected aspects of relational wisdom and implications for therapeutic practice. © 2015 Family Process Institute.

Dans le cadre de l'utilisation de ces instruments pour l'acquisition de données en mer, afin de quantifier les vagues ou la houle, des visualisations annexes, involontaires à l'origine, ont été réalisées. C'est le cas, par exemple, de certains fonds marins, que l'on peut voirlorsque quelques éléments opérationnels sont bien choisis. De plus, une certaine idée de leur morphologie peut être atteinte. Divers exemples sont présentés dans le cas de faibles fonds. Une approche des causes de cette visualisation est proposée, les grandes limites en sont fixées. Side-looking radars are remote-sensing instruments providing images of the ground surface overflown in almost all weather, i. e. day or night, with clear weather or through mist, fog, clouds or rain. These equipments, previously used to quantify sea waves and swell produced, in sonie cases, a noise which was later understood as being a signal, an expression of sea bottom features. This is the case, for example, for sonie sea floors which can be seenwhen a few operational elements have been carefully chosen. Likewise, some idea of the morphology of sea floors can be obtained. This article gives different examples for shallow depths. An approach to the causes of this visualization is proposed, and the major limitations are determined.

  17. Psalm 32 as a wisdom intertext

    2014-10-01

    Full Text Available Psalm 32 is considered by the majority of investigators to be a psalm of thanksgiving with a mix of wisdom poetry. In this article, the thesis is defended that it was devised from the beginning as a wisdom-teaching psalm although it simulates the form of a psalm of thanksgiving in certain respects. The case for this is argued on the basis of the complete integration of its parts, as well as its similarity to Proverbs 28:13–14 and some other wisdom texts. The aim of the psalmist seems to have been to argue (on the basis of a personal experience that stubbornness in accepting the guilt of sin causes suffering, but that Yahweh is eager to restore an intimate relationship with those worshippers who confess their guilt and are willing to accept his guidance on the way of life.

    2014-01-01

    Objectives. This study investigated the relationship of gratitude to wisdom. Both constructs are conceptually related to self-reflectivity, but they differ in their emphasis on extrapersonal resources. Previous wisdom research has focused mainly on intrapersonal capacities. Method. In Study 1, 47 wisdom nominees and 47 control participants were interviewed about their most difficult and best life event and filled out a questionnaire on sources of gratitude. Study 2 was a quantitative study (N = 443) of the relationship between a wisdom scale and scale measures and individual sources of gratitude. Results. Significantly more wisdom nominees expressed feelings of gratitude spontaneously in their interview. Wisdom nominees reported gratitude for their life in general, religion, and partner more often than control participants. In Study 2, wisdom was related to all gratitude scales and to similar sources of gratitude as in Study 1. Both studies found gender differences in gratitude but not wisdom. Discussion. Two important implications of these findings are that wisdom entails an appreciation of life and its experiences, especially the growth opportunities that may result from negative events, and that there may be substantial differences between male and female pathways to wisdom.

    2015-03-01

    Full Text Available The capacity for perspective taking is thought to be linked to psychological development and to wisdom. This article draws from psychological, contemplative, cross-cultural, and philosophical disciplines to create an inventory of perspectival skills and their possible relationships to wisdom. The nature of perspectives is explored, as are the characteristics of healthy perspectives, and the factors—such as developmental stage, assumptions, and state of mind—that determine the number and kinds of available perspectives. The article then examines rare postconventional perspectival capacities such as the ability to integrate multiple perspectives, to adopt higher order metaperspectives, and to experience transperspectival “pure awareness.” Fifteen kinds of wise perspectives and perspectival skills are suggested. Finally, the article reviews psychological, relational, contemplative, philosophical, and educational methods thought to foster perspectival skills and wisdom.

    There has been mixed evidence for age differences in wisdom-related knowledge across the adult life span. This study investigated two potential moderators of the link between age and wisdom-related knowledge: the wisdom criteria and the wisdom tasks. To test these moderators, 40 younger and 40 older participants completed four wisdom tasks differing in context-richness. Independent trained raters coded the resulting think-aloud protocols in terms of value relativism, as defined in the Berlin wisdom paradigm, and perspective taking, as defined by Grossmann. The type of task did not show any main or interaction effects on the present two wisdom criteria. However, age differences in the two wisdom criteria were multidirectional: whereas perspective taking did not differ by age group, value relativism was lower in older than younger adults. In addition, value relativism, but not perspective taking, was related to measures of fluid and crystallized intelligence, whereas perspective taking, but not value relativism, was related to a measure of life investment. This study provides evidence for the idea that value relativism and perspective taking are two distinct facets of wisdom-related knowledge. Implications for future age-comparative research interested in wisdom are discussed. © The Author(s) 2017. Published by Oxford University Press on behalf of The Gerontological Society of America.

    Full Text Available Daniel, Hananiah, Misael, and Azariah were young Jewish people who had been taken to Babylon in captivity. They truly obeyed God in their daily life and did not defile themselves with the king’s food and wine. God honored their decision so He gave them wisdom, that is intellectual ability (knowledge and understanding of all kinds of literature and learning and understanding visions and dreams of all kinds. Their response to the wisdom from God was having a good life style, submitting to God, and carrying burdens. To continue the wisdom from God, they lived in unity, depended on God and had God’s spirit in them. In doing their job, they spoke with wisdom and tact and worked honestly. In working with the king, they made a courageous decision not to worship the image of god and not to follow the king’s command. In the king’s palace, Daniel did not think for himself only, but had a burden to pray for Jerusalem, represent his nation before God, and fast for the future.

    Full Text Available This paper presents the results of qualitative study aimed to explore the relationship between the perception of behaviors that support people development, core coaching competences and values supporting them, and wisdom-related values. Our hypothesis was that the reflection on empowering behaviors focuses managers’ attention on wisdom-related values that are very close to the core values of coaching and therefore facilitate their progress towards wisdom-related performance. Sample consisted of 306 managers (N = 306 interviewed in 28 groups (N = 28 within leadership development programs in Russia, Ukraine and France from 2008 to 2016. We used the open-ended questions method and qualitative content analysis. The results showed high homogeneity of responses and high degree compatibility between behaviors quoted by respondents and the International Coach Federation core competences. In the second part of the study the responses were analyzed from the point of view of beliefs and values that can support desired developmentally focused / coaching behaviors, and compared the outcome with the existing concepts of wisdom. The study confirmed that the professional training in coaching leads to the cumulative development of wisdom (wisdom-related values, wisdom-related knowledge, wisdom-related performance because the core of the system of coaching values fundamentally coincide with wisdom-related values.

Exemplars also underwent lengthy semi-structured interviews to assess their lives, qualities, and understanding of wisdom. Interviews were analyzed for their significant themes. Results of this study suggest that exemplars of wisdom are humble, spiritual, mindful, insightful, tell the truth, and are open to experiences. They have meaningful, long-term relationships with mentors and loved ones. Exemplars are deeply influential in the lives of others and have very high life satisfaction. The 2 predominant definitions of wisdom given by exemplars were that wisdom is practical and comes from the unknown. Exemplars offered multiple strategies for the cultivation of wisdom-related processes, primarily the relationship with a mentor. Future research may clarify an emerging relationship between transcendent and practical wisdom.

    Full Text Available Theology, through its history, has always been related to Philology, because its source is the Holy Scriptures. This reason has stimulated my further consideration of the exegeta Gerhard von Rad “Wisdom in Israel” a “symbol” of modern interest for the Wisdom books. Inserted in the philologic German trend of the history of tradition and history of editing and forms, it is opposed to positivists interpretation and installs a new comprehension of the OT traditions. Its hermeneutica, without deteriorating the historical criticism, gives first hand priority to the message that the scriptural brands patentize as a twist of an organization in constant growth. However, the love of live words, which is considered by the philologist, make him capable to have a wide effect of the methodological tools, and in this way; unravel the secrets of the world of wisdom. Now in the threshold of Christianism, Wisdom books prepare the adequate opening to receive the “new Wine” in “new containers”. Also, today, philology and wisdom summon us to go along with this moment of the History of Salvation with the necessary instruments and ancient breeding by old and modern wisemen.

    2014-10-23

    ABSTRACT Background: Previous research on wisdom has suggested that wisdom is comprised of cognitive, reflective, and affective components and has developed and validated wisdom measures based on samples from Western countries. To apply the measurement to Eastern cultures, the present study revised an existing wisdom scale, the three-dimensional wisdom scale (3D-WS, Ardelt, 2003) for the Korean cultural context. Methods: Participants included 189 Korean heritage adults (age range 19-96) living in Los Angeles. We added a culturally specific factor of wisdom to the 3D-WS: Modesty and Unobtrusiveness (Yang, 2001), which captures an Eastern aspect of wisdom. The structure and psychometrics of the scale were tested. By latent cluster analysis, we determined acculturation subgroups and examined group differences in the means of factors in the revised wisdom scale (3D-WS-K). Results: Three factors, Cognitive Flexibility, Viewpoint Relativism, and Empathic Modesty were found using confirmatory factor analysis. Respondents with high biculturalism were higher on Viewpoint Relativism and lower on Empathic Modesty. Conclusion: This study discovered that a revised wisdom scale had a distinct factor structure and item content in a Korean heritage sample. We also found acculturation influences on the meaning of wisdom.

    2015-03-01

    Full Text Available How leaders experience wisdom is important to our understanding of leadership behavior as well as to our overall understanding of leadership. The article explores qualitative findings that may advance academic discourse and research at the intersection between leadership, wisdom, and constructive-developmental theory. The present study examined how 12 executive leaders who assessed at the conventional and post-conventional stages of adult development experience wisdom. It is significant in that it addresses a gap in the literature between wisdom and constructive-developmental theory. Semi-structured interviews were conducted to determine how executive leaders understand their leadership role in terms of the cognitive, reflective, and affective domains of wisdom. Contrary to research that defines and operationalizes wisdom as the integration of these domains, findings indicate that participants experience wisdom in one or more of the domains of wisdom. Participants were also assessed for their meaning-making capacity to determine their stage of development using the SCTi-Map instrument. Contrary to research in constructive-developmental theory that suggests that post-conventional levels of development may equate to higher levels of wisdom, findings also indicate that there was no significant difference between how leaders describe their propensity for wisdom and their measured adult stage of development. Leaders who assessed at both the conventional and post-conventional stages of development described a propensity for wisdom. Analysis of participant responses suggests that the wisdom, in all its complexity, has its own trajectory and therefore necessitates inquiry into the lines of human development to include integral perspectives associated with spiritual, emotional, and psychosocial measures. The results of this study indicate the potential for additional research that explores wisdom in the context of both adult lines and adult stages of

    2017-06-01

    Full Text Available The author argues that love should play a central role in philosophy (and ethics. In the past, philosophical practice has been too narrowly defined by theory and explanation. Although unquestionably important, they do not belong to the very core of our philosophizing. Philosophy is primarily a way of life, centered on the soul and the development of our humanity – in its most diverse aspects and to its utmost potential. For such a life to be possible, love must play a central role in philosophy and philosophy should be understood not in the traditional sense as “the love of wisdom,” but in a new way – as the wisdom of love.

    Full Text Available Management of watersheds becomes part of a government program. This was conducted to anticipate the floods that hit the settlement. But the program is hard to do without the active role of the community, therefore the communication activities were undertaken based on local wisdom. The purpose of this paper is to find out about the environmental communication based on local wisdom in the Citarum Watershed. The method used is in the form of interviews and participant observation. As for the results obtained are: local wisdom is utilized by the environment actuator in the Citarum watershed management in the form of the proverb, rituals, and the environment preservation. Local wisdom by the environment actuator is meant as a way in, and domain in conducting environmental communication. In addition, local wisdom considered by the environment actuator as the ethic to be met in interacts with the target communities. Implementation of environmental communication activities with local wisdom based on the Citarum is done through a personal approach to some of the social and religious figures by using the communication channels of the group in the forum -the farmers group, majelis ta’lim, and community empowerment, which proceeds in a dialogical way to reach mutual agreement based on mutual trust among the participants of the environmental communication

    2012-01-01

    At both a micro-information level and a macro-societal level, the concepts of “knowledge” and “wisdom” are complementary – in both decisions and in social structures and institutions.  At the decision level, knowledge is concerned with how to make a proper choice of means, where “best” is measured as the efficiency toward achieving an end.  Wisdom is concerned with how to make a proper choice of ends  that attain “best” values. At a societal level, knowledge is managed through science/technology and innovation.  And while science/technology is society's way to create new means with high efficiencies, they reveal nothing about values.  Technology can be used for good or for evil, to make the world into a garden or to destroy all life.  It is societal wisdom which should influence the choice of proper ends -- ends to make the world a garden. How can society make progress in wisdom as well as knowledge?  Historically, the disciplines of the physical sciences and biology have provided sci...

    Full Text Available In the present work I approach a topic of great complexity, always anchored in social actuality because it addresses to an extremely sensitive area in which law is intertwined with the human wisdom. I start from the reality that human spiritual balance as an obvious sign of human wisdom can be maintained in a secured social balance of the social order, as a manifestation of this virtue at a community level. I insist on the interferences between universal and social order in which is enrolled as an individual component the legal order. The specificity of this latter form of the inter-human relations is ensured by the peculiar physiognomy of law rules. There are rules of human behaviour which although present some own features to other social norms (generality, impersonality, typicality, these stand out by their obligation which allows, when necessary, to be done using coercive state power. Both creation and especially interpretation and application of the law rules, involves the legislature wisdom, to impose people legal orders which to order and discipline their relations with the environment in which they live and other members of human community so as to make possible a social balance and harmonious coexistence of humans. Legal order gives concreteness and expression to some fundamental valences of law: justice, equity and righteousness. Therefore, in the vast majority of live situations, especially in cases in which norms of law express “the will of the many”, they convince through their correctness and validity, harmonizing with the interests and aspirations of those whom are addressed, which exclude the intervention of human coercive force. Here, is a sign of human wisdom. But also as a sign of human wisdom can be considered appropriate and necessary the coercive intervention of the state, when the violation of a right occurred, the social order (also the legal one being more or less disturbed. In these situations, law intervention is

    Scientists have traditionally collected data on whether a population is increasing, decreasing, or staying the same, but such studies are often limited by geographic scale and time frame. This means that for many species, understanding of trends comes from only part of their ranges at particular periods. Working with citizen scientists has the potential to overcome these limits. Citizen science has the added benefit of exposing citizens to the scientific process and engaging them in management outcomes. We examined a different way of using citizen scientists (instead of data collection). We asked community members to answer a question directly and thus examined whether community wisdom can inform conservation. We reviewed the results of 3 mail-in surveys that asked community members to say whether they thought koala populations were increasing, decreasing, or staying the same. We then compared the survey results with population trends derived from more traditional research. Population trends identified through community wisdom were similar to the trends identified by traditional research. The community wisdom surveys, however, allowed the question to be addressed at much broader geographical scales and time frames. Studies that apply community wisdom have the benefit of engaging a broad section of the community in conservation research and education and therefore in the political process of conserving species. © 2016 Society for Conservation Biology.

    Full Text Available This article focuses on a research project that was designed to inquire into the cultivation of wisdom in the classroom in the context of a newly implemented school subject called Glück (English: happiness. Glück was introduced in order to make a difference in traditional mainstream schooling as a reaction to school curricula that emphasize data and knowledge transfer. It is different and new because it embraces the kind of learning that includes the senses, the mind, body, spirit and the guts. Its multidimensional approach makes an attempt to validate a renunciation of the reductionistic perspective of traditional and contemporary schooling. How it is implemented served as a transformational process through a set of experiential exercises, group discussions, contemplative practices, teamwork etc. It is my aim to give an insight into what I understood as an alternative learning arena embedded in a traditional schooling system and the implications for further development beyond the transfer of data and information in adolescents. Zooming in on Glück, I aim to provide some perspectives on how key experiences and the reflection upon them can lead to the cultivation of wisdom. The understanding of cultivating wisdom I have gained from this study is that it is a dynamic process where the creation of new structures of meaning making emerge through the interaction with others, with oneself and the reflection upon one’s own interior processes that can help unfold, know how to use and refine tacit knowledge. Part of this process is actively discovering and transforming complex information in order to embody it and make it one’s own. Due to the assumption that traditional schooling mostly puts an emphasis on conveying informational knowledge (Hart, 2009; Sternberg, 2001 (to the more or less attentive students and another assumption that wisdom is often seen in connection to age, this article makes an attempt to give an alternative perspective.

    Full Text Available Muḥmood Sami al Barodi is a famous poet who was named the Resurrector of poetry in the early times when many poets of the old era were the cause of the decline in poetry. His poems had been studied from many aspects and by many scholars but no one ever spoke about al Barodi’s writings about wisdom. This article is focusing on the verses and poems that focus on the meaning of wisdom and everything that relate to it. He talked about the importance of wisdom in the poems as he encouraged the other poets to give attention to this meaning. Some published books and articles helped me write this article but I haven’t found any of them that gave this point enough significance though his poetry is full of verses about wisdom and so I chose to write about it..

    Full Text Available The goal of the article is to study factors that determine a necessity of expansion of the essence of the “human capital” notion in the context of changing priorities of economic growth and transition to the “wisdom society”. The article reveals, in the result of the analysis, that wisdom becomes the priority at the modern stage of social and economic development and the main challenge – leaving the limits of the “knowledge society” and developing into the “wisdom society”. Consequently, the humanitarian economy (“wisdom economy” is shown as the main direction of development of the economic science. Moreover, the article shows that the concept of human capital should be expanded with consideration of specific features of the wisdom society. The article offers to understand the human capital as an aggregate of knowledge, skills, motivations (according to Becker plus wisdom (happiness, imperative of values and subjectness. Prospects of further studies are connected with the search for methods of measurement of such a difficult to measure property as “happiness”, comparison of the heuristic potential of the existing indices and, possibly, their specification or development of new ones.

    Full Text Available Radar sensor networks, including bi- and multi-static radars, provide several operational advantages, like reduced vulnerability, good system flexibility and an increased radar cross-section. However, radar-to-radar interference suppression is a major problem in distributed radar sensor networks. In this paper, we present a cross-matched filtering-based radar-to-radar interference suppression algorithm. This algorithm first uses an iterative filtering algorithm to suppress the radar-to-radar interferences and, then, separately matched filtering for each radar. Besides the detailed algorithm derivation, extensive numerical simulation examples are performed with the down-chirp and up-chirp waveforms, partially overlapped or inverse chirp rate linearly frequency modulation (LFM waveforms and orthogonal frequency division multiplexing (ODFM chirp diverse waveforms. The effectiveness of the algorithm is verified by the simulation results.

  20. The Conceptual Review of Interaction between Corporate Wisdom and Corporate Entrepreneurship

    2017-12-01

    Full Text Available Wisdom is an important point of view in the literature as the highest desired attainment of knowledge management and a new goal. Wisdom is a mysterious concept existing at the top of the hierarchy of data, information, and knowledge that occurs by the evolving of knowledge with experience and thought. This concept constitutes institutional wisdom when dealt with on an institutional basis. Today's competition conditions move corporate wisdom understanding on the agenda due to the insufficiency of traditional knowledge management approach towards sustainable targets and keeping the business vulnerable to rapidly changing conditions. Entrepreneurship is one of the most popular phenomena influenced by the developments in knowledge management. Entrepreneurship necessitates the creation of value by seeing opportunities, reaching different information before others, and using it differently from others, thereby becoming a member of the information society. Entrepreneurship processes aiming to create value through transformation and innovation studies in an existing organization are called "corporate entrepreneurship". Corporate entrepreneurship is a capability that enables businesses to gain competitive advantage through conscious efforts which actuate internal and external initiatives against changing conditions and uncertainties. It is thought that the factors of corporate wisdom understanding are interacting with elements of corporate entrepreneurship. In this study, a conceptual review is carried out in order to reveal the mentioned interaction, to take all dimensions of the elements which the concepts are based on.

  2. Wisdom of the Body in Sport and Exercise Practices

    2017-10-01

    Full Text Available Two alternative ancient views on medicine and health can be distinguished in western antiquity: first, that the knowledge of the doctor is sufficient, and second, that health is primarily a consequence of adapting one’s own life to the wisdom of the body. The body works according to its own laws, has its own “logic,” and speaks its own language. Therefore, listening to the body can be an important source of information for a healthy human life. The body is not merely an object for human manipulation and “the prison of the soul,” but a source of learning and knowledge. It seems that people rarely listen to their own bodies; however, the ancient wisdom of listening to the body is still present and cultivated in modern sports training. Good athletes and trainers are the ones who learn from the body and recognize its messages. In this article, we focus on four aspects of wisdom of the body, presented through four virtues: prudence, justice, fortitude, and temperance. The body teaches us temperance and justice; for example, when someone exaggerates too much, the body produces the feeling of pain. The body is a source of fortitude and persistence when rest and healing is needed. The body is a source of prudence or truth about oneself when we face the physical demands of sport. Therefore, through modern sports practices, the perennial wisdom of the body is still accessible to the modern man.

    This study examined whether gender moderated the association between age cohort and the cognitive, reflective, and compassionate dimensions of wisdom, using an Iranian sample of 439 adults from three age cohorts: young (18-34), middle-aged (35-54), and older (55 and above). Results indicated that the interaction effect between gender and age cohort was significant for three-dimensional wisdom and all three wisdom dimensions. Compared with younger women and older men, older women tended to have less education and to score lower on the cognitive wisdom dimension, but they had similar average scores as older men on the compassionate wisdom dimension. Overall, the association between age and wisdom was only positive for men, due mainly to the positive relation between age and the reflective and compassionate wisdom dimensions for men after adjusting for education. The results are interpreted with reference to generation gaps, socialization of men versus women, and life experiences and opportunities. © The Author(s) 2015.

  7. Humor as Wisdom for Reframing Life.

    2018-04-01

    Human beings inevitably experience anxiety but attempt to avoid facing it through various forms of self-deception. This avoidance can lead to pathological symptoms. Young and middle-aged adults may be especially susceptible to suffering from anxiety because they are often single-mindedly pursuing means of achieving security. For these and others who fail to embrace life with warm enthusiasm, humor can serve to alleviate stress. This article views humor as a characteristic disposition of older adults-their humor signifying a sense of integrity and wisdom that often accompanies the aging process. Humor binds together feelings of despair and joy and contributes to a faithful reframing of faith and life. This article proposes that individuals acquire humor by perceiving the world as if on a journey to an exotic new place, seeing with new eyes even the most mundane of everyday objects and events. This capacity to perceive beauty in the ordinary world reflects a wisdom of older adults potentially available even to the young.

    2013-10-01

    To illustrate through the interpretation of one representative nurse manager's narrative how the methodology of practice articulation gives language to the ways practical wisdom develops in leadership practice and facilitates learning. Patricia Benner's corpus of research has demonstrated that reflection on clinical narratives comes closer than other pedagogical methods to replicating and enhancing the experiential learning required for the development of practical wisdom. Using Benner's methodology of practice articulation, 91 nurse managers wrote and read to a peer group a narrative of their lived experience in the role. The groups interpreted the narratives to extract the skilled knowledge and ethics embedded in the practice of the nurse manager authors. One narrative was chosen for this paper because it is a particularly clear exemplar of how practical wisdom develops in nurse manager practice. Articulating and reflecting on experiential learning led to an understanding of how practical wisdom developed in one nurse manager's practice. Interpretation of the narrative of one nurse manager illustrated how reflection on a complex ethical dilemma was a source of character development for the individual and the peer group. Describing and interpreting how practical wisdom develops for individual nurse managers can be a source of learning for the narrative author and other role incumbents who need to make sound decisions and take prudent action in ethically challenging situations. © 2013 John Wiley & Sons Ltd.

    Lee, Michael D; Zhang, Shunan; Shi, Jenny

    2011-07-01

    In The Price Is Right game show, players compete to win a prize, by placing bids on its price. We ask whether it is possible to achieve a "wisdom of the crowd" effect, by combining the bids to produce an aggregate price estimate that is superior to the estimates of individual players. Using data from the game show, we show that a wisdom of the crowd effect is possible, especially by using models of the decision-making processes involved in bidding. The key insight is that, because of the competitive nature of the game, what people bid is not necessarily the same as what they know. This means better estimates are formed by aggregating latent knowledge than by aggregating observed bids. We use our results to highlight the usefulness of models of cognition and decision-making in studying the wisdom of the crowd, which are often approached only from non-psychological statistical perspectives.

    Kamli, Emna

    Les radars hautes-frequences (RHF) mesurent les courants marins de surface avec une portee pouvant atteindre 200 kilometres et une resolution de l'ordre du kilometre. Cette etude a pour but de caracteriser la performance des RHF, en terme de couverture spatiale, pour la mesure des courants de surface en presence partielle de glace de mer. Pour ce faire, les mesures des courants de deux radars de type CODAR sur la rive sud de l'estuaire maritime du Saint-Laurent, et d'un radar de type WERA sur la rive nord, prises pendant l'hiver 2013, ont ete utilisees. Dans un premier temps, l'aire moyenne journaliere de la zone ou les courants sont mesures par chaque radar a ete comparee a l'energie des vagues de Bragg calculee a partir des donnees brutes d'acceleration fournies par une bouee mouillee dans la zone couverte par les radars. La couverture des CODARs est dependante de la densite d'energie de Bragg, alors que la couverture du WERA y est pratiquement insensible. Un modele de fetch appele GENER a ete force par la vitesse du vent predite par le modele GEM d'Environnement Canada pour estimer la hauteur significative ainsi que la periode modale des vagues. A partir de ces parametres, la densite d'energie des vagues de Bragg a ete evaluee pendant l'hiver a l'aide du spectre theorique de Bretschneider. Ces resultats permettent d'etablir la couverture normale de chaque radar en absence de glace de mer. La concentration de glace de mer, predite par le systeme canadien operationnel de prevision glace-ocean, a ete moyennee sur les differents fetchs du vent selon la direction moyenne journaliere des vagues predites par GENER. Dans un deuxieme temps, la relation entre le ratio des couvertures journalieres obtenues pendant l'hiver 2013 et des couvertures normales de chaque radar d'une part, et la concentration moyenne journaliere de glace de mer d'autre part, a ete etablie. Le ratio des couvertures decroit avec l'augmentation de la concentration de glace de mer pour les deux types

  16. Diverticular Disease: Reconsidering Conventional Wisdom

    Science.gov (United States)

    Peery, Anne F.; Sandler, Robert S.

    2013-01-01

    Colonic diverticula are common in developed countries and complications of colonic diverticulosis are responsible for a significant burden of disease. Several recent publications have called into question long held beliefs about diverticular disease. Contrary to conventional wisdom, studies have not shown that a high fiber diet protects against asymptomatic diverticulosis. The risk of developing diverticulitis among individuals with diverticulosis is lower than the 10–25% commonly quoted, and may be as low as 1% over 11 years. Nuts and seeds do not increase the risk of diverticulitis or diverticular bleeding. It is unclear whether diverticulosis, absent diverticulitis or overt colitis, is responsible for chronic gastrointestinal symptoms or worse quality of life. The role of antibiotics in acute diverticulitis has been challenged by a large randomized trial that showed no benefit in selected patients. The decision to perform elective surgery should be made on a case-by-case basis and not routinely after a second episode of diverticulitis, when there has been a complication, or in young people. A colonoscopy should be performed to exclude colon cancer after an attack of acute diverticulitis but may not alter outcomes among individuals who have had a colonoscopy prior to the attack. Given these surprising findings, it is time to reconsider conventional wisdom about diverticular disease. PMID:23669306

    AMGA is a gLite-metadata catalogue service designed to offer access to metadata for files stored on the Grid. We evaluated AMGA to analyze whether it is suitable for the WISDOM environment, where thousands of jobs access it simultaneously to get metadata describing docking results and the status of jobs. In this work, we address performance issues on AMGA and propose new techniques to improve AMGA performance in the WISDOM environment. In the WISDOM environment, thousands of job agents distributed on the Grid may have access to an AMGA server simultaneously (1) to take docking tasks out of the AMGA server to execute on the machine that they are sitting, (2) to get the related ligand and target information, and (3) to store the docking results. The docking tasks take about 10 to 30 minutes to finish depending on the machine that they run and the docking configuration. We have carried out some performance analysis on the current AMGA implementation. Due to the overhead required to handle GSI/SSL connection on t...

    2016-01-01

    This article argues that it is necessary to go back to Potter's proposal to rediscover a concept of bioethics wider than medical ethics, and strongly connected to environmental ethics. The two disciplines share, among others, the following dimensions: the consciousness of the sin as a consequence of recent technological developments; the need for a salvation; the need for a science of survival; wisdom as a possible solution. Referring to the latter, the work of Van Rennselaer Potter (father of bioethics) and Arne Næss (father of deep ecology, and in a broader sense, of environmental ethics) are particularly linked: it seems that wisdom should be the virtue providing answers about our way of dwelling the world. Finally, we will argue about the need for a practical wisdom (phronesis) for the future of environmental ethics.

    Practical wisdom, understood as knowing how to be or act in any present situation with clients, is believed to be an essential part of the knowledge needed to be a professional mental health worker. Exploring processes of adapting, extending knowledge and refining tacit knowledge grounded in mental health workers' experiences with being in practice may bring awareness of how mental health workers reflect, learn and practice professional 'artistry'. The aim of the article was to explore mental health workers' processes of development and learning as they appeared in focus groups intended to develop practical wisdom. The main research question was 'How might the processes of development and learning contribute to developing practical wisdom in the individual as well as in the practice culture?' The design was multi-stage focus groups, and the same participants met four times. A phenomenological hermeneutical method for researching lived experience guided the analysis. Eight experienced mental health workers representing four Norwegian municipalities participated. The research context was community-based mental health services. The study was reported to Norwegian Social Data Services, and procedures for informed consent were followed. Two examples of processes of re-evaluation of experience (Association, Integration, Validation, Appropriation and Outcomes and action) were explored. The health workers had developed knowledge in previous encounters with clients. In sharing practice experiences, this knowledge was expressed and developed, and also tested and validated against the aims of practice. Discussions led to adapted and extended knowledge, and as tacit knowledge was expressed it could be used actively. Learning to reflect, being ready to be provoked and learning to endure indecisiveness may be foundational in developing practical wisdom. Openness is demanding, and changing habits of mind is difficult. Reflection on, and confrontation with, set practices are

    Social groups can be remarkably smart and knowledgeable when their averaged judgements are compared with the judgements of individuals. Already Galton [Galton F (1907) Nature 75:7] found evidence that the median estimate of a group can be more accurate than estimates of experts. This wisdom of crowd effect was recently supported by examples from stock markets, political elections, and quiz shows [Surowiecki J (2004) The Wisdom of Crowds]. In contrast, we demonstrate by experimental evidence (N = 144) that even mild social influence can undermine the wisdom of crowd effect in simple estimation tasks. In the experiment, subjects could reconsider their response to factual questions after having received average or full information of the responses of other subjects. We compare subjects’ convergence of estimates and improvements in accuracy over five consecutive estimation periods with a control condition, in which no information about others’ responses was provided. Although groups are initially “wise,” knowledge about estimates of others narrows the diversity of opinions to such an extent that it undermines the wisdom of crowd effect in three different ways. The “social influence effect” diminishes the diversity of the crowd without improvements of its collective error. The “range reduction effect” moves the position of the truth to peripheral regions of the range of estimates so that the crowd becomes less reliable in providing expertise for external observers. The “confidence effect” boosts individuals’ confidence after convergence of their estimates despite lack of improved accuracy. Examples of the revealed mechanism range from misled elites to the recent global financial crisis. PMID:21576485

    Introduction: Personal wisdom has demonstrated important implications for the health of individuals. The aim of the present study was to validate a Spanish version of the Three-Dimensional Wisdom Scale (3D-WS), exploring the structure of a possible general factor, and assessing its explanatory power on psychological health-related variables. Methods: A cross-sectional study design was used, with a total sample of 624 Spanish participants recruited on the Internet and randomly split into two halves. The following instruments were applied: 3D-WS, Purpose in Life (PIL), Multidimensional State Boredom Scale (MSBS), Positive and Negative Affect Scale (PANAS), and Difficulties in Emotion Regulation Scale (DERS). Factorial structures were analyzed through exploratory and confirmatory factor analysis (EFA and CFA), and the general factor was characterized by using bifactor models. The explanatory power of the 3D-WS was established by multiple regression. Results: The original long and short versions of the 3D-WS were not replicated in the first subsample using EFA, and there was a high rate of cross-loadings. Thus, a new short 3D-WS was proposed by ordering the original items according to factorial weights. This three-correlated-factor (reflective, cognitive, and affective) proposal was tested by means of CFA in the second subsample, with adequate psychometrics and invariance, and a good fit (χ 2 /df = 1.98; CFI = 0.946; RMSEA = 0.056; 90% CI = 0.040-0.072). A bifactor structure, in which the reflective trait of wisdom was integrated into a general factor (G-Reflective) improved the model fit (χ 2 /df = 1.85; CFI = 0.959; RMSEA = 0.052; 90% CI = 0.035-0.070). The explained common variance of G-Reflective was 0.53; therefore, the new short 3D-WS should not be considered essentially unidimensional. The new short 3D-WS showed positive relationships with the PIL and PANAS-positive, and negative associations with the MSBS, PANAS-negative and DERS, contributing to explain all

    Full Text Available The WeIzmann Supercooled Droplets Observation on Microarray (WISDOM is a new setup for studying ice nucleation in an array of monodisperse droplets for atmospheric implications. WISDOM combines microfluidics techniques for droplets production and a cryo-optic stage for observation and characterization of freezing events of individual droplets. This setup is designed to explore heterogeneous ice nucleation in the immersion freezing mode, down to the homogeneous freezing of water (235 K in various cooling rates (typically 0.1–10 K min−1. It can also be used for studying homogeneous freezing of aqueous solutions in colder temperatures. Frozen fraction, ice nucleation active surface site densities and freezing kinetics can be obtained from WISDOM measurements for hundreds of individual droplets in a single freezing experiment. Calibration experiments using eutectic solutions and previously studied materials are described. WISDOM also allows repeatable cycles of cooling and heating for the same array of droplets. This paper describes the WISDOM setup, its temperature calibration, validation experiments and measurement uncertainties. Finally, application of WISDOM to study the ice nucleating particle (INP properties of size-selected ambient Saharan dust particles is presented.

    2013-07-01

    Full Text Available The article revisits the thesis of Walter Beyerlin from 1980 that Psalm 52 is a paraenetic- didactic Wisdom poem from the late Persian period. Beyerlin reached his conclusion from a comparison of Psalm 52 with post-exilic Wisdom psalms such as Psalms 37, 49, and 73. The direct literary influence that Psalm 52 received from the book of Proverbs and the motifs it shares with Jeremiah 9 are investigated here, since the author contends that the Wisdom influence on the Psalm was even greater than Beyerlin had envisaged. The article comes to the conclusion that the author(s of the Psalm attempted to compose a psalm by establishing a network of allusions to a corpus of authoritative texts, inter alia, the Wisdom psalms. The end product is a brilliant composition which interprets the teaching of Proverbs for the needs of a group of Jewish believers who probably lived at the end of the Persian period.

    Full Text Available World life expectancy is increasing and many populations will begin to age rapidly. The impeding prevalence of a greater number of older people living longer lives will have significant social and economic implications. It is important to understand how older people make economic and social decisions. Aging can be associated with a ‘phenomenon of decline’ and also greater wisdom. This paper seeks to examine the relationship between wisdom and aging. It reviews and connects the behavioral sciences and neuroscience literature on age differences in the following social and economic decision making domains that represent subcomponents of wisdom: 1 prosocial behavior in experimental economic games and competitive situations, 2 resolving social conflicts, 3 emotional homeostasis, 4 self-reflection, 5 dealing effectively with uncertainty in the domains of risk, ambiguity and intertemporal choice. Overall, we find a lack of research into how older people make economic and social decisions. There is, however, some evidence that older adults outperform young adults on certain subcomponents of wisdom, but the exact relationship between old age and each subcomponent remains unclear. A better understanding of these relationships holds the potential to alleviate a wide range of mental health problems, and has broad implications for social policies aimed at the elderly.

  18. Metaphors in the Wisdom Literature of the Hebrew Bible and Contemporary Art

    Directory of Open Access Journals (Sweden)

    Bálint Károly Zabán

    2016-08-01

    Full Text Available Biblical wisdom literature is a treasure-trove of powerful metaphors. This article presents a sample of these metaphors and their significant impact on contemporary artwork. The impact is characterized by both appropriation and adaptation, similitude and analogy, respectively. The highlighted metaphors are not merely catalogued but, more or less, analyzed with regard to relevant contemporary artwork. This augments the importance of contemporary biblical literacy analysis and uses it as one of the tools by which it is possible to gauge the impact and interaction, in this case, of the metaphor-world of the wisdom tradition on contemporary art. More importantly, however, this study underscores the relevance of these metaphors for biblical exegesis, hermeneutics, and theology. The analysis of the reception of these metaphors in contemporary artworks undergirds and informs the process of interpretation. The reception of these metaphors in their contemporary art contexts is best understood within the framework of imagery and imagistic language. Metaphor, as a subset of imagery and imagistic language, is foundational for the examined wisdom books, Proverbs, Job, and Qoheleth, and for the relevant contemporary artwork, alike. Moreover, metaphor also constitutes a bridge between the ancient and contemporary context. With this backdrop in mind, this article argues for the necessity of exploring the connections between these wisdom books, metaphor studies, and contemporary artwork.

    Full Text Available Abstract In their commentary, Dar and Frenk call into question the validity of all published data that describe the onset of nicotine addiction. They argue that the data that describe the early onset of nicotine addiction is so different from the conventional wisdom that it is irrelevant. In this rebuttal, the author argues that the conventional wisdom cannot withstand an application of the scientific method that requires that theories be tested and discarded when they are contradicted by data. The author examines the origins of the threshold theory that has represented the conventional wisdom concerning the onset of nicotine addiction for 4 decades. The major tenets of the threshold theory are presented as hypotheses followed by an examination of the relevant literature. Every tenet of the threshold theory is contradicted by all available relevant data and yet it remains the conventional wisdom. The author provides an evidence-based account of the natural history of nicotine addiction, including its onset and development as revealed by case histories, focus groups, and surveys involving tens of thousands of smokers. These peer-reviewed and replicated studies are the work of independent researchers from around the world using a variety of measures, and they provide a consistent and coherent clinical picture. The author argues that the scientific method demands that the fanciful conventional wisdom be discarded and replaced with the evidence-based description of nicotine addiction that is backed by data. The author charges that in their attempt to defend the conventional wisdom in the face of overwhelming data to the contrary, Dar and Frenk attempt to destroy the credibility of all who have produced these data.

    Full Text Available In this paper, the definition and the key features of Software Radar, which is a new concept, are proposed and discussed. We consider the development of modern radar system technology to be divided into three stages: Digital Radar, Software radar and Intelligent Radar, and the second stage is just commencing now. A Software Radar system should be a combination of various modern digital modular components conformed to certain software and hardware standards. Moreover, a software radar system with an open system architecture supporting to decouple application software and low level hardware would be easy to adopt "user requirements-oriented" developing methodology instead of traditional "specific function-oriented" developing methodology. Compared with traditional Digital Radar, Software Radar system can be easily reconfigured and scaled up or down to adapt to the changes of requirements and technologies. A demonstration Software Radar signal processing system, RadarLab 2.0, which has been developed by Tsinghua University, is introduced in this paper and the suggestions for the future development of Software Radar in China are also given in the conclusion.

    Full Text Available Three questions form the basis of this analysis of the relationship of the Epistle of James to the traditions of wisdom, eschatology and apocalypticism. What kind of traditions are involved in James? What is the world view of James? What audience or community is presupposed by this writing? Foremost is the connection that James demonstrates to the wisdom tradition evident in the Old Testament and extratestamental literature. In particular two types of wisdom tradition are noted in James: practical wisdom advice as expressed in short sayings, wisdom instructions and admonitions and reflection on the nature of wisdom (1:5-8; 2:1-7; and 3:13-18 as coming from God. Finally, the question of how much apocalyptic symbolism is evident in the eschatological world view of the epistle is addressed.

  10. The tacit care knowledge in reflective writing – a practical wisdom

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Background: The Norwegian municipal welfare system provides home healthcare and residential services to a growing population of older people. The skills and competence of the personnel providing these services need to keep pace with demand, and continuing education is vital. A concern, though, is the way positivist knowledge permeates both education and healthcare services; recognising other types of knowledge, such as tacit knowledge together with practical wisdom, is important to complement the focus on evidence-based practice. Aims and objectives: This article addresses the need for healthcare professionals to develop open-minded reflection in writing and in action, as keys to expressing tacit knowledge and thus making it more visible. Moreover, tacit knowledge may also represent practical wisdom, or ‘phronesis’. The aim is to bring forward examples of the often invisible and unrecognised expertise held by experienced nurses and other healthcare professionals. Method: This discussion paper is based on reflection notes written by students doing continuing education in advanced gerontology. Some of the situational dilemmas that students bring forward in their texts are retold, and these stories represent traces of tacit care knowledge, and practical wisdom or phronesis. Findings: Reflection may strengthen students’ ethical autonomy and imagination, which is important in healthcare professionals’ caregiving. Reflective writing is part of the educational pathway and contributes to the development of personal tacit knowledge and wisdom. The experiences put forward in the student’s stories become part of their ability to act and care; this embodied knowledge is understood as part of what phronesis might be. Implications for practice: Fostering healthcare professionals’ self-awareness through reflection can help them come to a realisation and understanding that opens up new alternatives for action Reflection may increase awareness of

    The change in coexistence pattern of elements (antagonism-synergism) in conditions of excessive level of toxic element is observed in many biological samples. The aim of this study was to establish the cadmium and zinc content in hard tissues of retained wisdom teeth of smokers and non-smokers and to find out if active exposure to cigarette smoke has an influence on coexistence of both metals in these tissues. Material consisted of 127 retained wisdom teeth (65 from smokers and 62 from non-smokers). Cadmium and zinc contents were determined by means of atomic absorption spectrometry. We found out that retained wisdom tooth from smokers exhibited higher cadmium and zinc contents compared to non-smokers' teeth. Moreover, coexistence pattern of cadmium and zinc in teeth depends on exposure to heavy metals and exhibits strong synergism in smokers.

    This paper presents a demonstration of how Local Area Weather Radar (LAWR) X-band measurements can be combined with meteorological C–band measurements into a single radar product. For this purpose, a blending method has been developed which combines the strengths of the two radar systems. Combining...... the two radar types achieves a radar product with both long range and high temporal resolution. It is validated that the blended radar product performs better than the individual radars based on ground observations from laser disdrometers. However, the data combination is challenged by lower performance...... of the LAWR. Although both radars benefits from the data combination, it is also found that advection based temporal interpolation is a more favourable method for increasing the temporal resolution of meteorological C–band measurements....

  18. The Effects of the MORE Wisdom Resources on Spousal Caregivers' Life Satisfaction: An Application of the Resilience Model.

    Science.gov (United States)

    Kim, Seungyoun; Knight, Bob G

    2017-01-01

    Models of resilience suggest that psychosocial resources and their interactions facilitate resilience while experiencing life challenges of caregiving. The MORE wisdom resources (sense of Mastery, Openness to experience, Reflective attitude, and Emotion regulation) have been suggested as possible personal resources of resilience that predict positive health outcomes of caregivers. Applying a model of resilience, this study examined the direct and indirect effects of the three of the MORE wisdom resources (sense of Mastery, Openness to experience, and Emotion regulation) on caregiving spouses' life satisfaction and perceived physical health. Using data from the survey of Midlife in the United States, caregiving spouses (n = 114) and matched non-caregivers (n = 114) were included. We compared the direct and indirect effects of the wisdom resources on life satisfaction and physical health between the two groups. The simple mediation model proposed in 2008 by Preacher and Hayes revealed that openness to experience was directly associated with better life satisfaction among caregiving spouses. Sense of mastery and emotion regulation had indirect effects on life satisfaction through spousal support. The effects the wisdom resources on caregiving spouses' perceived physical health were not found. This study demonstrated that the three of the MORE wisdom resources are possible personal resilience factors influencing life satisfaction among caregiving spouses. Moreover, the study showed how spousal support mediates the relationship between the wisdom resources and life satisfaction. Interventions aiming to increase life satisfaction among caregiving spouses should focus on increasing both personal and environmental resources and strengthening the relationship of the caregiver and care recipient.

  19. The implementation of local wisdom in reducing natural disaster risk: a case study from West Sumatera

    2018-01-01

    The purpose of this paper is to introduce some local wisdoms in West Sumatra and propose their challenges that modern values have degraded its knowledge. In a contemporary context, traditional stories (written and oral stories) still relevant to be used and internalized in disaster risk reduction. Traditional knowledge or local wisdom is a system of knowledge derived from long experienced process in the past, adopted and handed over to next generation through evolutionary process. Indigenous or traditional knowledge can be practiced in understanding the nature of natural disaster, to propose the best action in mitigation, to respond in emergency phase, and to suggest more option for recovery process based on previous experience. The paper based on four weeks field research in west Sumatra which is known with their natural hazards due to its geographical location. In the beginning, this paper discusses the nature of local wisdom and how it can be matched in disaster management, then continues to the specific case how the traditional stories in West Sumatera can be internalized and integrated with contemporary disaster risk reduction. This paper proves that local wisdom can be useful as an effective instrument to deal with natural disaster or natural hazard.

  2. Teaching practical wisdom in medicine through clinical judgement, goals of care, and ethical reasoning.

    Kaldjian, Lauris Christopher

    2010-09-01

    Clinical decision making is a challenging task that requires practical wisdom-the practised ability to help patients choose wisely among available diagnostic and treatment options. But practical wisdom is not a concept one typically hears mentioned in medical training and practice. Instead, emphasis is placed on clinical judgement. The author draws from Aristotle and Aquinas to describe the virtue of practical wisdom and compare it with clinical judgement. From this comparison, the author suggests that a more complete understanding of clinical judgement requires its explicit integration with goals of care and ethical values. Although clinicians may be justified in assuming that goals of care and ethical values are implicit in routine decision making, it remains important for training purposes to encourage habits of clinical judgement that are consciously goal-directed and ethically informed. By connecting clinical judgement to patients' goals and values, clinical decisions are more likely to stay focused on the particular interests of individual patients. To cultivate wise clinical judgement among trainees, educational efforts should aim at the integration of clinical judgement, communication with patients about goals of care, and ethical reasoning. But ultimately, training in wise clinical judgement will take years of practice in the company of experienced clinicians who are able to demonstrate practical wisdom by example. By helping trainees develop clinical judgement that incorporates patients' goals of care and ethical reasoning, we may help lessen the risk that 'clinical judgement' will merely express 'the clinician's judgement.'

  3. Relationship among Patience, Gratitude and Wisdom according to Maturidi

    Full Text Available Patience is in the face of hardships and troubles experienced, and showing steadiness by turning negative situations into positive ones; gratitude is shown for the blessings and goodness coming from God or man and is expressed in words and phrases. One of ahl al-Sunnah scholars, Abu Mansur al-Maturidite (ö. 333 / 944 also used gratitude and patience concepts close to each other although there is a nuance. And patience is used for accepting the calamities and scourges, gratitude is used for accepting the blessings from God. Not only God tested Adam whether he will approach the forbidden tree, but also He is testing Adam‘s sons in every state and situation with patience and gratitude. This trial takes place with the servant‘s patience towards calamities and scourges and his/her gratitude for the blessings. Whatever the servant is exposed to is the necessity of wisdom and a secret reason. Thus, Maturidite influenced the subsequent scholars with his wisdom view on patience and gratitude. This study will evaluate the views of Maturidi on patience and gratitude.

    Full Text Available Tomato is a climacteric fruit, which is characterized by ripening-related increase of respiration and elevated ethylene synthesis. Ethylene is the key hormone in ripening process of climacteric fruits. The objective of this research is to study the expression of three ethylene synthesis genes: LeACO1, LeACS1A, LeACS2, and a housekeeping gene LeGAPDH in ripening tomato fruit. Specific primers have been designed to amplify complementary DNA fragment of LeGAPDH (143 bp, LeACO1 (240 bp, LeACS1A (169 bp, and LeACS2 (148 bp using polymerase chain reaction. Nucleotide BLAST results of the complementary DNA fragments show high similarity with LeGAPDH (NM_001247874.1, LeACO1 (NM_001247095.1, LeACS1A (NM_001246993.1, LeACS2 (NM_001247249.1, respectively. Expression study showed that LeACO1, LeACS1A, LeACS2, and LeGAPDH genes were expressed in ripening tomato fruit. Isolation methods, reference sequences, and primers used in this study can be used in future experiments to study expression of genes responsible for ethylene synthesis using quantitative polymerase chain reaction and to design better strategy for controlling fruit ripening in agroindustry.

  5. Cross Validation of Rain Drop Size Distribution between GPM and Ground Based Polarmetric radar

    Chandra, C. V.; Biswas, S.; Le, M.; Chen, H.

    2017-12-01

    Dual-frequency precipitation radar (DPR) on board the Global Precipitation Measurement (GPM) core satellite has reflectivity measurements at two independent frequencies, Ku- and Ka- band. Dual-frequency retrieval algorithms have been developed traditionally through forward, backward, and recursive approaches. However, these algorithms suffer from "dual-value" problem when they retrieve medium volume diameter from dual-frequency ratio (DFR) in rain region. To this end, a hybrid method has been proposed to perform raindrop size distribution (DSD) retrieval for GPM using a linear constraint of DSD along rain profile to avoid "dual-value" problem (Le and Chandrasekar, 2015). In the current GPM level 2 algorithm (Iguchi et al. 2017- Algorithm Theoretical Basis Document) the Solver module retrieves a vertical profile of drop size distributionn from dual-frequency observations and path integrated attenuations. The algorithm details can be found in Seto et al. (2013) . On the other hand, ground based polarimetric radars have been used for a long time to estimate drop size distributions (e.g., Gorgucci et al. 2002 ). In addition, coincident GPM and ground based observations have been cross validated using careful overpass analysis. In this paper, we perform cross validation on raindrop size distribution retrieval from three sources, namely the hybrid method, the standard products from the solver module and DSD retrievals from ground polarimetric radars. The results are presented from two NEXRAD radars located in Dallas -Fort Worth, Texas (i.e., KFWS radar) and Melbourne, Florida (i.e., KMLB radar). The results demonstrate the ability of DPR observations to produce DSD estimates, which can be used subsequently to generate global DSD maps. References: Seto, S., T. Iguchi, T.

    1983-01-01

    Airborne radar approach (ARA) concepts are being investigated as a part of NASA's Rotorcraft All-Weather Operations Research Program on advanced guidance and navigation methods. This research is being conducted using both piloted simulations and flight test evaluations. For the piloted simulations, a mathematical model of the airborne radar was developed for over-water ARAs to offshore platforms. This simulated flight scenario requires radar simulation of point targets, such as oil rigs and ships, distributed sea clutter, and transponder beacon replies. Radar theory, weather radar characteristics, and empirical data derived from in-flight radar photographs are combined to model a civil weather/mapping radar typical of those used in offshore rotorcraft operations. The resulting radar simulation is realistic and provides the needed simulation capability for ongoing ARA research.

    We have now entered the age of wisdom to leave the era of hunters and gatherers, an agricultural and industrial age, information and knowledge workers. Today, if someone managed efficiently will produce high income and developing countries. Change from one era to another will generate more revenues with high risk to workers lost their jobs. Most valuable asset of an organization in 20 th century is knowledge workers and their productivity. Their mind set must be converted into a comprehensive human paradigm with levels of compliance and maximum job contribution is required. Similarly, talent management and self-potential of the staff also are needed. The problem is most of the current management system still strongly tied to the industrial era. A transformation had to be implemented to use the wisdom of the time management system. Corporate nature based on true, honesty, fairness, knowing one, focus on the contribution and universal spiritual and eternal nature is very much needed. (author)

  10. WISDOM: A GIS-based supply demand mapping tool for woodfuel management

    International Nuclear Information System (INIS)

    Masera, Omar; Ghilardi, Adrian; Drigo, Rudi; Angel Trossero, Miguel

    2006-01-01

    In this paper, it is argued that adequately assessing the implications of the current patterns of woodfuel production and use, and the sustainable potentials of woodfuel resources, requires a holistic view and a better knowledge of the spatial patterns of woodfuel supply and demand. There is a need to conduct multi-scale spatially explicit analyses of woodfuel supply and demand that are able to articulate local heterogeneity at the regional and national levels. Studies that provide full-country coverage and are based on consistent integration of data at lower geographical scales are woefully lacking. This paper describes the Woodfuel Integrated Supply/Demand Overview Mapping model (WISDOM). This is a GIS-based tool, aimed at analyzing woodfuel demand and supply spatial patterns from a new perspective that includes: (a) the assembling of existing but dispersed information into single data sets, (b) a modular integration of these data sets, based on the analysis of key variables associated with woodfuel demand and supply patterns, and (c) a multiple-scale and spatially explicit representation of the results, in order to rank or highlight areas in which several criteria of interest coincide. The final objective of WISDOM is to assess the sustainability of woodfuel as a renewable and widespread energy source, while supporting strategic planning and policy formulation. Three case studies for Mexico, Slovenia, and Senegal illustrate the practical implementation and innovative results of using WISDOM. (author)

    2014-09-01

    The radar experiment connects the geometry of spacetime with an observers measurement of spatial length. We investigate the radar experiment on Finsler spacetimes which leads to a general definition of radar orthogonality and radar length. The directions radar orthogonal to an observer form the spatial equal time surface an observer experiences and the radar length is the physical length the observer associates to spatial objects. We demonstrate these concepts on a forth order polynomial Finsler spacetime geometry which may emerge from area metric or premetric linear electrodynamics or in quantum gravity phenomenology. In an explicit generalization of Minkowski spacetime geometry we derive the deviation from the Euclidean spatial length measure in an observers rest frame explicitly.

    Perry, Tam E.; Hassevoort, Luke; Ruggiano, Nicole; Shtompel, Natalia

    2014-01-01

    According to Erik Erikson’s theory on the stages of human development, achieving wisdom later in life involves revisiting previous crises and renewing psychosocial accomplishments. However, few studies have used Erikson’s theory as a framework for examining how older adults self-manage physical and mental health changes that commonly occur later in life. This paper presents findings from two qualitative studies that demonstrate how older adults apply wisdom in new domains. Specifically, it was found that older adults (1) reasserted autonomy by initiating creative problem solving; and 2) applied skills gained from productive activities earlier in life to new health-related problems that arise later in life. These findings highlight the importance of engaging older adults to repurpose their life skills, and thus reapply wisdom to new areas of their lives. Implications for practice are discussed.

    Full Text Available One of the existing natural and environmental uses in Aceh (Indonesia is tourism. One of the aspects that determine the development and sustainability of tourism is the institutional and community aspects. Sustainable tourism is a picture of the ecosystem sustainability and socio-economic development of the community. This study aims to reveal and find local wisdom practices and explore local knowledge owned by Sabang Island community in the management and conservation of the environment so as to support the realization of sustainable tourism. This study uses rationalistic paradigm and uses qualitative research method. The data that has been collected is analyzed descriptively. Local wisdom and local knowledge are reflected in how society has a unique way of looking at and understanding nature and interacting with it. In the Aceh community, there are customary institutions that regulate the rules or interactions of the community with the environment, including “panglima laot”, “keujreun blang”, “peutua seuneubok”, “pawang glee or peutua uteun”, “haria peukan” and “syahbanda”. Local wisdom and local knowledge have great potential in maintaining, preserving and sustainability of the environment used by communities to meet their living needs. Ecological, social and religious intelligence formed through local wisdom and local knowledge can be an aspect in maintaining environmental sustainability in order to build sustainable tourism on Sabang Island.

    Full text: A Workshop to extend the Involvement of Stakeholders in Decisions On restoration Management (WISDOM) will be held in Oxford in September 2003. The aim of the workshop is to promote awareness and interest in the wider application of stakeholder involvement in the formulation of strategies for the management of contaminated agricultural land and produce following a nuclear accident. A network of stakeholder groups has already been set up under the auspices of the European Communities 5th Framework Programme (FP5). The network, given the acronym FARMING, involves more than 100 stakeholders in UK, Finland, Belgium, Greece and France. Membership tends to be at a senior level and comprises a wide range of Government and non-government organizations, including the farming sector, the food, milk and water industries, consumers and green groups. The stakeholder groups have met regularly since 2001 and have advanced contingency planning and emergency response, both nationally and on a European basis. A compendium of countermeasure options produced by another FP5 project, STRATEGY, has helped provide stakeholders with a common focus for discussion and evaluation. The 2 1/2 day workshop comprises a mixture of invited and proffered papers as well as facilitated group discussions and plenary sessions that will address the following issues: lessons learnt from stakeholder engagement; influence of regional characteristics on countermeasure selection; practical aspects of countermeasure implementation; crisis management; maintaining consumer confidence; acceptability of intervention limits; social, ethical and economic consequences; future prospects for stakeholder networks. More than 30 FARMING stakeholders and facilitators have expressed an interest in attending the WISDOM workshop. GOs and NGOs will both be represented. There will also be representatives from the STRATEGY project and the European Commission. Invitations have been issued to representatives of a further

    Group decisions and even aggregation of multiple opinions lead to greater decision accuracy, a phenomenon known as collective wisdom. Little is known about the neural basis of collective wisdom and whether its benefits arise in late decision stages or in early sensory coding. Here, we use electroencephalography and multi-brain computing with twenty humans making perceptual decisions to show that combining neural activity across brains increases decision accuracy paralleling the improvements shown by aggregating the observers' opinions. Although the largest gains result from an optimal linear combination of neural decision variables across brains, a simpler neural majority decision rule, ubiquitous in human behavior, results in substantial benefits. In contrast, an extreme neural response rule, akin to a group following the most extreme opinion, results in the least improvement with group size. Analyses controlling for number of electrodes and time-points while increasing number of brains demonstrate unique benefits arising from integrating neural activity across different brains. The benefits of multi-brain integration are present in neural activity as early as 200 ms after stimulus presentation in lateral occipital sites and no additional benefits arise in decision related neural activity. Sensory-related neural activity can predict collective choices reached by aggregating individual opinions, voting results, and decision confidence as accurately as neural activity related to decision components. Estimation of the potential for the collective to execute fast decisions by combining information across numerous brains, a strategy prevalent in many animals, shows large time-savings. Together, the findings suggest that for perceptual decisions the neural activity supporting collective wisdom and decisions arises in early sensory stages and that many properties of collective cognition are explainable by the neural coding of information across multiple brains.

    The multiple-input multiple-output (MIMO) radar concept has drawn considerable attention recently. In the traditional single-input multiple-output (SIMO) radar system, the transmitter emits scaled versions of a single waveform. However, in the MIMO radar system, the transmitter transmits independent waveforms. It has been shown that the MIMO radar can be used to improve system performance. Most of the MIMO radar research so far has focused on the uniform array. However, i...

    2014-01-01

    Despite the centrality of time to the aging process, the well-being consequences of different temporal orientations for optimal aging are poorly understood. We investigate one underexamined area of temporal orientation, namely a balanced time perspective, in a large, lifespan sample from the Netherlands. Participants consisted of 512 Dutch adults ranging in age from 17 to 92 years (Mage = 46.46, SD = 21.37), including 186 male and 326 females. Participants completed a measure of balanced time perspective, mental health, and wisdom. RESULTS indicated that a balanced time perspective uniquely predicted both mental health and wisdom even after controlling for demographic, physical health, and personality variables. Younger adults tended to be more future-oriented relative to older adults while older adults tended to be more past-oriented relative to younger adults. Further, both midlife and younger adults were more likely to have a balanced time perspective relative to older adults. A balanced time perspective is associated with higher well-being and wisdom across the adult age span.

  19. The wisdom of nature in integrating science, ethics and the arts.

    Science.gov (United States)

    Moser, A

    2000-07-01

    This paper deals with an approach to the integration of science (with technology and economics), ethics (with religion and mysticism), the arts (aesthetics) and Nature, in order to establish a world-view based on holistic, evolutionary ethics that could help with problem solving. The author suggests that this integration is possible with the aid of "Nature's wisdom" which is mirrored in the macroscopic pattern of the ecosphere. The corresponding eco-principles represent the basis for unifying soft and hard sciences resulting in "deep sciences". Deduction and induction will remain the methodology for deep sciences and will include conventional experiments and aesthetic and sentient experiences. Perception becomes the decisive factor with the senses as operators for the building of consciousness through the subconscious. In this paper, an attempt at integrating the concepts of the "true", the "right" and the "beautiful" with the aid of Nature's wisdom is explained in more detail along with consequences.

    Clinical courses following two-stage mandibular wisdom tooth extraction (TMWTE) carried out for preventing postoperative mental nerve paresthesia (MNP) were analyzed. When panoramic X-ray showed overlapping of wisdom tooth root on the superior 1/2 or more of the mandibular canal, interruption of the white line of the superior wall of the canal, or diversion of the canal, CT examination was facilitated. In cases where contact between the tooth root and canal was demonstrated in CT examination, TMWTE was then selected after gaining the patient's consent. TMWTE consisted of removing more than a half of the tooth crown and tooth root extraction at the second step after 2-3 months. The clinical features of wisdom teeth extracted and postoperative courses including tooth movement and occurrence of MNP during two-stage MWTE were evaluated. TMWTE was carried out for 40 teeth among 811 wisdom teeth (4.9%) that were extracted from 2007 to 2009. Among them, complete procedures were accomplished in 39 teeth, and crown removal was performed insufficiently at the first-stage operation in one tooth. Tooth movement was detected in 37 of 40 cases (92.5%). No postoperative MNP was observed in cases in which complete two-stage MWTE was carried out, but one case with insufficient crown removal was complicated by postoperative MNP. Seven mild complications (dehiscence, cold sensitivity, etc.) were noted after the first-stage operation. Therefore, we conclude that TMWTE for high-risk cases assessed by X-ray findings is useful to avoid MNP after MWTE. (author)

  4. Theory of mind and wisdom: The development of different forms of perspective-taking in late adulthood.

    How does perspective-taking develop over the lifespan? This question has been investigated in two separate research traditions, dealing with theory of mind (ToM) and wisdom, respectively. Operating in almost complete isolation from each other, and using rather different conceptual approaches, these two traditions have produced seemingly contradictory results: While perspective-taking has been consistently found to decline in old age in ToM research, studies on wisdom have mostly found that perspective-taking remains constant or sometimes even increases in later adulthood. This study sought to integrate these two lines of research and clarify the seemingly contradictory patterns of findings by systematically testing for both forms of perspective-taking and their potential cognitive foundations. The results revealed (1) the dissociation in developmental patterns between ToM perspective-taking (declining with age) and wisdom-related perspective-taking (no decline with age) also held - documented here for the first time - in one and the same sample of younger versus older adults; (2) this dissociation was of limited generality: It did not (or only partly) hold once the material of the two types of tasks was more closely matched; and (3) the divergent developmental patterns of ToM perspective-taking versus wisdom-related perspective-taking could be accounted for to some degree by the fact that only TOM perspective-taking was related to developmental changes in fluid intelligence. © 2017 The British Psychological Society.

    Whether wisdom is a culturally-specific or universal construct is a matter of some debate (see Curnow 1999; Grossman et al. Psychological Science, 2012). This study compared similarities and differences in the factor structure of a measure of wisdom focused on self-transcendence in U.S. (n = 305, M(age) = 33.99) and Korean samples (n = 838, M(age) = 30.28), with ages ranging from 20 to 73). The Adult Self-Transcendence Inventory (ASTI; Levenson et al. International Journal of Aging and Human Development, 60, 127-143, 2005) has two factors, self-transcendence and alienation, the latter of which was included to differentiate between social withdrawals due to contemplative practices versus that due to depression. Confirmatory factor analyses found a partial scalar factorial invariance model fit the data best, indicating that the factor structure of the ASTI is largely equivalent and that the construct is comparable across the two cultures. Regression analyses showed that age and religiousness were related to self-transcendence and alienation. Education was related to self-transcendence only. The interaction between age and culture was significant on alienation; alienation was higher in mid-life Koreans but not in Americans, which may reflect either age or cohort effects. Thus, self-transcendence may be a more universal measure of wisdom than those based on pragmatics or cognitive functioning.

  8. The Strengths of Wisdom Provide Unique Contributions to Improved Leadership, Sustainability, Inequality, Gross National Happiness, and Civic Discourse in the Face of Contemporary World Problems

    Directory of Open Access Journals (Sweden)

    Igor Grossmann

    2018-04-01

    Full Text Available We present evidence for the strengths of the intellectual virtues that philosophers and behavioral scientists characterize as key cognitive elements of wisdom. Wisdom has been of centuries-long interest for philosophical scholarship, but relative to intelligence largely neglected in public discourse on educational science, public policy, and societal well-being. Wise reasoning characteristics include intellectual humility, recognition of uncertainty, consideration of diverse viewpoints, and an attempt to integrate these viewpoints. Emerging scholarship on these features of wisdom suggest that they uniquely contribute to societal well-being, improve leadership, shed light on societal inequality, promote cooperation in Public Goods Games and reduce political polarization and intergroup-hostility. We review empirical evidence about macro-cultural, ecological, situational, and person-level processes facilitating and inhibiting wisdom in daily life. Based on this evidence, we speculate about ways to foster wisdom in education, organizations, and institutions.

  9. Determination of radar MTF

    Chambers, D. [Lawrence Livermore National Lab., CA (United States)

    1994-11-15

    The ultimate goal of the Current Meter Array (CMA) is to be able to compare the current patterns detected with the array with radar images of the water surface. The internal wave current patterns modulate the waves on the water surface giving a detectable modulation of the radar cross-section (RCS). The function relating the RCS modulations to the current patterns is the Modulation Transfer Function (MTF). By comparing radar images directly with co-located CMA measurements the MTF can be determined. In this talk radar images and CMA measurements from a recent experiment at Loch Linnhe, Scotland, will be used to make the first direct determination of MTF for an X and S band radar at low grazing angles. The technical problems associated with comparing radar images to CMA data will be explained and the solution method discussed. The results suggest the both current and strain rate contribute equally to the radar modulation for X band. For S band, the strain rate contributes more than the current. The magnitude of the MTF and the RCS modulations are consistent with previous estimates when the wind is blowing perpendicular to the radar look direction.

    2005-01-01

    Java Radar Analysis Tool (JRAT) is a computer program for analyzing two-dimensional (2D) scatter plots derived from radar returns showing pieces of the disintegrating Space Shuttle Columbia. JRAT can also be applied to similar plots representing radar returns showing aviation accidents, and to scatter plots in general. The 2D scatter plots include overhead map views and side altitude views. The superposition of points in these views makes searching difficult. JRAT enables three-dimensional (3D) viewing: by use of a mouse and keyboard, the user can rotate to any desired viewing angle. The 3D view can include overlaid trajectories and search footprints to enhance situational awareness in searching for pieces. JRAT also enables playback: time-tagged radar-return data can be displayed in time order and an animated 3D model can be moved through the scene to show the locations of the Columbia (or other vehicle) at the times of the corresponding radar events. The combination of overlays and playback enables the user to correlate a radar return with a position of the vehicle to determine whether the return is valid. JRAT can optionally filter single radar returns, enabling the user to selectively hide or highlight a desired radar return.

    Greg Park argues that corporate superstars collapse not primarily due to poor products, inadequate market penetration, financial mismanagement or self-aggrandisement, but rather by a leadership lacking the fundamental values, principles, perspectives, attributes and capabilities for long term organisational survival. The resultant inadequate cognitive mental process of leadership invites inevitable failure, through loss of confidence, motivation, cohesion, advocacy and energy amongst the community of stakeholders. Collaborative wisdom is the existence within the dominant coalition of an organi

    Wisdom of the Martians of Science refers to five scientists whose brilliance contributed to shaping the modern world. John von Neumann was a pioneer of the modern computer; Theodore von Kármán was the scientist behind the US Air Force; Leo Szilard initiated the development of nuclear weapons; the Nobel laureate Eugene P Wigner was the world's first nuclear engineer; and Edward Teller was the father of the hydrogen bomb. They were born and raised in Budapest, were forced out of Hungary and then from Germany, they became Americans, and devoted themselves to the defense of the United States and the Free World. They contributed significant discoveries to fundamental science ranging from the properties of materials to the application of the symmetry principle in physics, to creating information theory, to game theory. The areas in which we can learn about their wisdom include applications of science to past, present and future real-world needs; defense; education; environment; human nature; humor; politics; rel...

    In the face of the black swan events which frequently happened globally, I take the earthquake of Ya'an, happened at 4.20 in Sichuan, as an example of my subject. The results indicate that the social responsibility of landscape architects is a post-disaster reconstruction of a material and spiritual homeland for victims and mental care for individuals, which specifically reflected in the process of rebuilding victims' sense of security. The reconstruction of a sense of security must follow certain ethics and moralities which embody the ecological wisdom. We take a typical case of Ya'an Lushan Snow Mountain Village-the earthquake distress area, we found the incidence of disease was up to 68.6% through the PTSD analysis, indicating the overall absence of a sense of security. To solve the problem and reconstruct people's mental and material homeland, the article discussed the strategies and solutions to post-disaster landscape design based on traditional ethical wisdom.

    Full Text Available This paper deals with a new through-the-wall (TTW radar demonstrator for the detection and the localisation of people in a room (in a noncooperative way with the radar situated outside but in the vicinity of the first wall. After modelling the propagation through various walls and quantifying the backscattering by the human body, an analysis of the technical considerations which aims at defining the radar design is presented. Finally, an ultrawideband (UWB frequency modulated continuous wave (FMCW radar is proposed, designed, and implemented. Some representative trials show that this radar is able to localise and track moving people behind a wall in real time.

  8. Development of Radar Control system for Multi-mode Active Phased Array Radar for atmospheric probing

    2016-07-01

    Modern multi-mode active phased array radars require highly efficient radar control system for hassle free real time radar operation. The requirement comes due to the distributed architecture of the active phased array radar, where each antenna element in the array is connected to a dedicated Transmit-Receive (TR) module. Controlling the TR modules, which are generally few hundreds in number, and functioning them in synchronisation, is a huge task during real time radar operation and should be handled with utmost care. Indian MST Radar, located at NARL, Gadanki, which is established during early 90's, as an outcome of the middle atmospheric program, is a remote sensing instrument for probing the atmosphere. This radar has a semi-active array, consisting of 1024 antenna elements, with limited beam steering, possible only along the principle planes. To overcome the limitations and difficulties, the radar is being augmented into fully active phased array, to accomplish beam agility and multi-mode operations. Each antenna element is excited with a dedicated 1 kW TR module, located in the field and enables to position the radar beam within 20° conical volume. A multi-channel receiver makes the radar to operate in various modes like Doppler Beam Swinging (DBS), Spaced Antenna (SA), Frequency Domain Interferometry (FDI) etc. Present work describes the real-time radar control (RC) system for the above described active phased array radar. The radar control system consists of a Spartan 6 FPGA based Timing and Control Signal Generator (TCSG), and a computer containing the software for controlling all the subsystems of the radar during real-time radar operation and also for calibrating the radar. The main function of the TCSG is to generate the control and timing waveforms required for various subsystems of the radar. Important components of the RC system software are (i) TR module configuring software which does programming, controlling and health parameter monitoring of the

    Mokole, Eric L.; Hansen, Pete

    The development of UWB radar over the last four decades is very briefly summarized. A discussion of the meaning of UWB is followed by a short history of UWB radar developments and discussions of key supporting technologies and current UWB radars. Selected UWB radars and the associated applications are highlighted. Applications include detecting and imaging buried mines, detecting and mapping underground utilities, detecting and imaging objects obscured by foliage, through-wall detection in urban areas, short-range detection of suicide bombs, and the characterization of the impulse responses of various artificial and naturally occurring scattering objects. In particular, the Naval Research Laboratory's experimental, low-power, dual-polarized, short-pulse, ultra-high resolution radar is used to discuss applications and issues of UWB radar. Some crucial issues that are problematic to UWB radar are spectral availability, electromagnetic interference and compatibility, difficulties with waveform control/shaping, hardware limitations in the transmission chain, and the unreliability of high-power sources for sustained use above 2 GHz.

    The success of radar sensors in several different application areas of interest depends on the knowledge of the backscatter of radar waves from the targets of interest, the variance of these interaction mechanisms with respect to changing measurement parameters, and the determination of the influence of he measuring systems on the results. The incidence-angle dependency of the radar cross section of different natural targets is derived. Problems involved by the combination of data gained with different sensors, e.g., MSS-, TM-, SPOTand SAR-images are analyzed. Radar cross-section values gained with ground-based radar spectrometers and spaceborne radar imaging, and non-imaging scatterometers and spaceborne radar images from the same areal target are correlated. The penetration of L-band radar waves into vegetated and nonvegetated surfaces is analyzed.

  17. Meteor detection on ST (MST) radars

    International Nuclear Information System (INIS)

    Avery, S.K.

    1987-01-01

    The ability to detect radar echoes from backscatter due to turbulent irregularities of the radio refractive index in the clear atmosphere has lead to an increasing number of established mesosphere - stratosphere - troposphere (MST or ST) radars. Humidity and temperature variations are responsible for the echo in the troposphere and stratosphere and turbulence acting on electron density gradients provides the echo in the mesosphere. The MST radar and its smaller version, the ST radar, are pulsed Doppler radars operating in the VHF - UHF frequency range. These echoes can be used to determine upper atmosphere winds at little extra cost to the ST radar configuration. In addition, the meteor echoes can supplement mesospheric data from an MST radar. The detection techniques required on the ST radar for delineating meteor echo returns are described

    A new dual-frequency (Ku and Ka band) nadir-pointing Doppler radar on the high-altitude NASA ER-2 aircraft, called the High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP), has collected data over severe thunderstorms in Oklahoma and Kansas during the Midlatitude Continental Convective Clouds Experiment (MC3E). The overarching motivation for this study is to understand the behavior of the dualwavelength airborne radar measurements in a global variety of thunderstorms and how these may relate to future spaceborne-radar measurements. HIWRAP is operated at frequencies that are similar to those of the precipitation radar on the Tropical Rainfall Measuring Mission (Ku band) and the upcoming Global Precipitation Measurement mission satellite's dual-frequency (Ku and Ka bands) precipitation radar. The aircraft measurements of strong hailstorms have been combined with ground-based polarimetric measurements to obtain a better understanding of the response of the Ku- and Ka-band radar to the vertical distribution of the hydrometeors, including hail. Data from two flight lines on 24 May 2011 are presented. Doppler velocities were approx. 39m/s2at 10.7-km altitude from the first flight line early on 24 May, and the lower value of approx. 25m/s on a second flight line later in the day. Vertical motions estimated using a fall speed estimate for large graupel and hail suggested that the first storm had an updraft that possibly exceeded 60m/s for the more intense part of the storm. This large updraft speed along with reports of 5-cm hail at the surface, reflectivities reaching 70 dBZ at S band in the storm cores, and hail signals from polarimetric data provide a highly challenging situation for spaceborne-radar measurements in intense convective systems. The Ku- and Ka-band reflectivities rarely exceed approx. 47 and approx. 37 dBZ, respectively, in these storms.

    2018-04-01

    Full Text Available Human settlements are social-economic-natural complex ecosystems centered on human activities and the most prominent site for the contradictions between humans and the environment. Taking Hongcun, a UNESCO World Heritage site in China, as an example, this paper analyzes the methods and effect of coupling man and nature in Hongcun, summarizes the ecological wisdom of dealing with the relationship between human and nature, and uses this wisdom to shed light on the planning, construction, and management of contemporary urban and rural settlements. Firstly, the study introduces the Human-Natural Intergraded Ecological Planning (HNIEP model’s hypothesis, explaining its foundation and potential principles or approaches. Secondly, using the case study of Hongcun to explain, support, and validate the HNIEP model and its framework, the study found that the unique planning and construction of Hongcun has greatly promoted ecosystem services, such as local microclimate regulation, rainwater runoff regulation, water conservation, landscape aesthetic, and engagement with nature. Thirdly, Hongcun reflects the concept of harmonious coexistence between human and nature, the wisdom of rational use of ecosystem structures, processes and functions, and the wisdom of coupling human activities with the living environment and natural ecosystem. Finally, the paper summarizes the enlightenment brought by both the HNIEP model and Hongcun wisdom to contemporary urban-rural planning and construction management.

  4. Time series for water levels in virtual gauge stations in the Amazon basin using satellite radar altimetry

    Directory of Open Access Journals (Sweden)

    Juan Gabriel León Hernández

    2009-01-01

    Full Text Available Using satellite altimeter radar technology for monitoring changes in water levels at continental scale is a relatively recent ad- vance. Several studies have demonstrated the interest being shown in applying this technology to monitoring the hydrographic patterns of large-scale basins worldwide. The current study presents the inference of time series representing changes in water le- vel for bodies of water by defining virtual gauge stations deduced for two very different rivers in terms of their biophysical and to- pographic characteristics; the two rivers were the Rio Negro in the Brazilian Amazon Basin and the Caqueta River on the Colombian side. The differences between the two rivers revealed the limits of satellite radar altimeter when applied to continental waters (±20cm and ±40 cm precision for Río Negro and Río Caquetá, respectively. However, applying this technology seems very promising, since new missions have been scheduled to be put into orbit by the end of 2008.

  8. Challenging the Conventional Wisdom: From Philosophy to Bioethics.

    Science.gov (United States)

    Miller, Franklin G

    2017-01-01

    Philosophy is a core discipline that has contributed importantly to bioethics. In this essay, the author traces his trajectory from philosophy to bioethics, oriented around the theme of challenging the conventional wisdom. Three topics are discussed to illustrate this theme: the ethics of randomized trials, determination of death and organ transplantation, and pragmatism as a method of bioethics. In addition, the author offers some general reflections on the relationship between philosophy and bioethics. Philosophy recovers itself when it ceases to be a device for dealing with the problems of philosophers and becomes a method, cultivated by philosophers, for dealing with the problems of men.-John Dewey (1917).

  9. Network dynamics of social influence in the wisdom of crowds.

    Science.gov (United States)

    Becker, Joshua; Brackbill, Devon; Centola, Damon

    2017-06-27

    A longstanding problem in the social, biological, and computational sciences is to determine how groups of distributed individuals can form intelligent collective judgments. Since Galton's discovery of the "wisdom of crowds" [Galton F (1907) Nature 75:450-451], theories of collective intelligence have suggested that the accuracy of group judgments requires individuals to be either independent, with uncorrelated beliefs, or diverse, with negatively correlated beliefs [Page S (2008) The Difference: How the Power of Diversity Creates Better Groups, Firms, Schools, and Societies ]. Previous experimental studies have supported this view by arguing that social influence undermines the wisdom of crowds. These results showed that individuals' estimates became more similar when subjects observed each other's beliefs, thereby reducing diversity without a corresponding increase in group accuracy [Lorenz J, Rauhut H, Schweitzer F, Helbing D (2011) Proc Natl Acad Sci USA 108:9020-9025]. By contrast, we show general network conditions under which social influence improves the accuracy of group estimates, even as individual beliefs become more similar. We present theoretical predictions and experimental results showing that, in decentralized communication networks, group estimates become reliably more accurate as a result of information exchange. We further show that the dynamics of group accuracy change with network structure. In centralized networks, where the influence of central individuals dominates the collective estimation process, group estimates become more likely to increase in error.

  11. Interception of LPI radar signals

    Science.gov (United States)

    Lee, Jim P.

    1991-11-01

    Most current radars are designed to transmit short duration pulses with relatively high peak power. These radars can be detected easily by the use of relatively modest EW intercept receivers. Three radar functions (search, anti-ship missile (ASM) seeker, and navigation) are examined to evaluate the effectiveness of potential low probability of intercept (LPI) techniques, such as waveform coding, antenna profile control, and power management that a radar may employ against current Electronic Warfare (EW) receivers. The general conclusion is that it is possible to design a LPI radar which is effective against current intercept EW receivers. LPI operation is most easily achieved at close ranges and against a target with a large radar cross section. The general system sensitivity requirement for the detection of current and projected LPI radars is found to be on the order of -100 dBmi which cannot be met by current EW receivers. Finally, three potential LPI receiver architectures, using channelized, superhet, and acousto-optic receivers with narrow RF and video bandwidths are discussed. They have shown some potential in terms of providing the sensitivity and capability in an environment where both conventional and LPI signals are present.

    We report on the experimental demonstration of an FMCW radar operating in the 25.7 - 26.6 GHz range with a repetition rate of 500 sweeps per second. The radar is able to track the breathing rate of an adult human from a distance of 1 meter. The experiments have utilized a 50 second recording window...... to accurately track the breathing rate. The radar utilizes a saw tooth modulation format and a low latency receiver. A breath tracking radar is useful both in medical scenarios, diagnosing disorders such as sleep apnea, and for home use where the user can monitor its health. Breathing is a central part of every...... radar chip which, through the use of a simple modulation scheme, is able to measure the breathing rate of an adult human from a distance. A high frequency output makes sure that the radar cannot penetrate solid obstacles which is a wanted feature in private homes where people therefore cannot measure...

  15. Radar meteor rates and solar activity

    1983-01-01

    The short-term variation of diurnal radar meteor rates with solar activity represented by solar microwave flux Fsub(10.7), and sunspots relative number Rsub(z), is investigated. Applying the superposed-epoch analysis to the observational material of radar meteor rates from Christchurch (1960-61 and 1963-65), a decrease in the recorded radar rates is found during days of enhanced solar activity. No effect of geomagnetic activity similar to the one reported for the Swedish and Canadian radar meteor data was found by the author in the Christchurch data. A possible explanation of the absence of the geomagnetic effect on radar meteor rates from New Zealand due to a lower echo ceiling height of the Christchurch radar is suggested. The variation of the atmospheric parameters as a possible cause of the observed variation in radar meteor rates is also discussed. (author)

    This is the second edition of the first and foremost book on this subject for self-study, training, and course work. Radar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver.

    The annular region of enhanced radar reflectivity, known as the Bright Band (BB), occurs when the radar beam intersects a layer of melting hydrometeors. Radar reflectivity is related to rainfall through a power law equation and so this enhanced region can lead to overestimations of rainfall by a factor of up to 5, so it is important to correct for this. The BB region can be identified by using several techniques including hydrometeor classification and freezing level forecasts from mesoscale meteorological models. Advances in dual-polarisation radar measurements and continued research in the field has led to increased accuracy in the ability to identify the melting snow region. A method proposed by Kitchen et al (1994), a form of which is currently used operationally in the UK, utilises idealised Vertical Profiles of Reflectivity (VPR) to correct for the BB enhancement. A simpler and more computationally efficient method involves the formation of an average VPR from multiple elevations for correction that can still cause a significant decrease in error (Vignal 2000). The purpose of this research is to evaluate a method that relies only on analysis of measurements from an operational C-band polarimetric radar without the need for computationally expensive models. Initial results show that LDR is a strong classifier of melting snow with a high Critical Success Index of 97% when compared to the other variables. An algorithm based on idealised VPRs resulted in the largest decrease in error when BB corrected scans are compared to rain gauges and to lower level scans with a reduction in RMSE of 61% for rain-rate measurements.

    Full Text Available Le roman policier offre à l’étude du stéréotype une grande variété de redondances, lexicales et structurelles, qui permettent d’éclairer le concept même de genre, en fait issu du constat de stéréotypie. Il est également manifeste que contrairement aux idées reçues, les clichés font du texte policier un texte littéraire, parce qu’ils naissent d’images associées, distinctes de la réalité, qui révèlent d’ailleurs le cheminement même de l’écriture. Par ailleurs ces images jouent un rôle fondamental dans le plaisir du lecteur, comme dans les contes de fées de notre enfance. Les clichés ouvrent la porte des fantasmes : le stéréotype rejoignant l’archétype, les clichés policiers réactivent de nombreux mythes, le texte évoquant l’Autre Scène. Le constat de stéréotypie provoque l’écriture, en particulier parodique, et stimule le renouvellement et l’essaimage des clichés dans toutes sortes de textes, qui bénéficieront de la présence du déjà-lu, laquelle donne au lecteur une assise pour affronter l’inconnu et une expérience pour apprécier la nouveauté.

    In one embodiment, a radar communication system includes a plurality of radars having a communication range and being capable of operating at a sensing frequency and a reporting frequency, wherein the reporting frequency is different than the sensing frequency, each radar is adapted for operating at the sensing frequency until an event is detected, each radar in the plurality of radars has an identification/location frequency for reporting information different from the sensing frequency, a first radar of the radars which senses the event sends a reporting frequency corresponding to its identification/location frequency when the event is detected, and all other radars in the plurality of radars switch their reporting frequencies to match the reporting frequency of the first radar upon detecting the reporting frequency switch of a radar within the communication range. In another embodiment, a method is presented for communicating information in a radar system.

    2004-07-01

    In this paper, a novel radar management strategy technique suitable for RADAR/IRST track fusion, which is based on Fisher Information Matrix (FIM) and fuzzy stochastic decision approach, is put forward. Firstly, optimal radar measurements' scheduling is obtained by the method of maximizing determinant of the Fisher information matrix of radar and IRST measurements, which is managed by the expert system. Then, suggested a "pseudo sensor" to predict the possible target position using the polynomial method based on the radar and IRST measurements, using "pseudo sensor" model to estimate the target position even if the radar is turned off. At last, based on the tracking performance and the state of target maneuver, fuzzy stochastic decision is used to adjust the optimal radar scheduling and retrieve the module parameter of "pseudo sensor". The experiment result indicates that the algorithm can not only limit Radar activity effectively but also keep the tracking accuracy of active/passive system well. And this algorithm eliminates the drawback of traditional Radar management methods that the Radar activity is fixed and not easy to control and protect.

    Existing assessments of intellectual humility (IH)-a key component of wisdom-do not examine its manifestation in daily life while sufficiently focusing on the core idea of the construct: owning up to one's intellectual shortcomings. The present research sought to examine situational contingencies underlying daily manifestations of IH-relevant characteristics. We developed a trait version of the State-Trait IH Scale in two studies and subsequently examined daily manifestations of IH-relevant characteristics utilizing a contextualized state version of the State-Trait IH Scale in a 21-day experience sampling study. Here we tested how specific situational contingencies (associated with the context and the personality of the individual with whom participants engaged) influenced the manifestation of IH-relevant qualities. We found strong evidence for the validity of both versions of the scale. Specifically, the state measure exhibited high within-person variability, and aggregated state assessments were strongly correlated with the trait measure. Additionally, morality positively predicted manifestation of IH, while disagreeableness negatively predicted manifestation of IH. These results offer new directions for research on the expression of wisdom-related characteristics in daily life.

    2013-03-01

    Full Text Available What exactly is the difference between data and information? What is the difference between data quality and information quality; is there any difference between the two? And, what are knowledge and wisdom? Are there such things as knowledge quality and wisdom quality? As these primitives are the most basic axioms of information systems research, it is somewhat surprising that consensus on exact definitions seems to be lacking. This paper presents a theoretical and empirical exploration of the sometimes directly quoted, and often implied Data, Information, Knowledge, Wisdom (DIKW hierarchy and its quality dimension. We first review relevant literature from a range of perspectives and develop and contextualise a theoretical DIKW framework through semiotics. The literature review identifies definitional commonalities and divergences from a scholarly perspective; the theoretical discussion contextualises the terms and their relationships within a semiotic framework and proposes relevant definitions grounded in that framework. Next, rooted in Wittgenstein’s ordinary language philosophy, we analyse 20 online news articles for their uses of the terms and present the results of an online focus group discussion comprising 16 information systems experts. The empirical exploration identifies a range of definitional ambiguities from a practical perspective.

  13. The WISDOM Study: breaking the deadlock in the breast cancer screening debate.

    2017-01-01

    There are few medical issues that have generated as much controversy as screening for breast cancer. In science, controversy often stimulates innovation; however, the intensely divisive debate over mammographic screening has had the opposite effect and has stifled progress. The same two questions-whether it is better to screen annually or bi-annually, and whether women are best served by beginning screening at 40 or some later age-have been debated for 20 years, based on data generated three to four decades ago. The controversy has continued largely because our current approach to screening assumes all women have the same risk for the same type of breast cancer. In fact, we now know that cancers vary tremendously in terms of timing of onset, rate of growth, and probability of metastasis. In an era of personalized medicine, we have the opportunity to investigate tailored screening based on a woman's specific risk for a specific tumor type, generating new data that can inform best practices rather than to continue the rancorous debate. It is time to move from debate to wisdom by asking new questions and generating new knowledge. The WISDOM Study (Women Informed to Screen Depending On Measures of risk) is a pragmatic, adaptive, randomized clinical trial comparing a comprehensive risk-based, or personalized approach to traditional annual breast cancer screening. The multicenter trial will enroll 100,000 women, powered for a primary endpoint of non-inferiority with respect to the number of late stage cancers detected. The trial will determine whether screening based on personalized risk is as safe, less morbid, preferred by women, will facilitate prevention for those most likely to benefit, and adapt as we learn who is at risk for what kind of cancer. Funded by the Patient Centered Outcomes Research Institute, WISDOM is the product of a multi-year stakeholder engagement process that has brought together consumers, advocates, primary care physicians, specialists, policy

  15. Extended Target Recognition in Cognitive Radar Networks

    Directory of Open Access Journals (Sweden)

    Xiqin Wang

    2010-11-01

    Full Text Available We address the problem of adaptive waveform design for extended target recognition in cognitive radar networks. A closed-loop active target recognition radar system is extended to the case of a centralized cognitive radar network, in which a generalized likelihood ratio (GLR based sequential hypothesis testing (SHT framework is employed. Using Doppler velocities measured by multiple radars, the target aspect angle for each radar is calculated. The joint probability of each target hypothesis is then updated using observations from different radar line of sights (LOS. Based on these probabilities, a minimum correlation algorithm is proposed to adaptively design the transmit waveform for each radar in an amplitude fluctuation situation. Simulation results demonstrate performance improvements due to the cognitive radar network and adaptive waveform design. Our minimum correlation algorithm outperforms the eigen-waveform solution and other non-cognitive waveform design approaches.

    To make our cities weather ready and climate proof has become a fundamental societal issue in the context of an on-going urbanization and growing population density (http://www.nws.noaa.gov/com/weatherreadynation/). This is a challenging question in a region like Île-de-France, which corresponds to one of the largest, if not the largest, concentration of assets and infrastructures in Europe. More than ever, there is an urgent need to cross-fertilise research and operational hydrology, whereas they have both suffered from a long-lasting divorce (Schertzer et al., 2010). A preliminary step is to use the best available measurement technologies. In this presentation we discuss the potentials of the polarimetric X-band radar technology to measure small scale rainfalls in urban environment. Particularly intense rainy episodes have struck hard various regions of France during the period of May-June 2016, notably Ile-de-France and its neighbourhoods. The data collected during those days by the X-band radar of Ecole des Pont ParisTech (http://www.enpc.fr/hydrologie-meteorologie-et-complexite) allow to observe the fast aggregation of strong cells of small sizes in a multi-cellular thunderstorm. Certain cells make initially hardly more than a radar pixel (250m x 250m), while just three quarters of hour later they form a multi-cellular well-organised thunderstorm over tenths of kilometres. These observations have triggered the development of new methods of immediate forecast taking into account the multi-scale and strongly intermittent character of such rainfall fields to better manage the crises, particularly for strongly vulnerable urban systems. We present the results of the multifractal analysis and simulations of the polarimetric X-band radar data that first contribute to better understanding of the three-dimensional dynamics of such events, and then allows representing of how strong cores of haste precipitation contribute to the rainfall amounts striking the ground.

    Since the catastrophic Sumatra-Andaman tsunami took place in 2004, 16 other tsunamis have resulted in significant damage and 14 in casualties. We review the fundamental changes that have affected our command of tsunami issues as scientists, engineers and decision-makers, in the quest for improved wisdom in this respect. While several scientific paradigms have had to be altered or abandoned, new algorithms, e.g. the W seismic phase and real-time processing of fast-arriving seismic P waves, give us more powerful tools to estimate in real time the tsunamigenic character of an earthquake. We assign to each event a 'wisdom index' based on the warning issued (or not) during the event, and on the response of the population. While this approach is admittedly subjective, it clearly shows several robust trends: (i) we have made significant progress in our command of far-field warning, with only three casualties in the past 10 years; (ii) self-evacuation by educated populations in the near field is a key element of successful tsunami mitigation; (iii) there remains a significant cacophony between the scientific community and decision-makers in industry and government as documented during the 2010 Maule and 2011 Tohoku events; and (iv) the so-called 'tsunami earthquakes' generating larger tsunamis than expected from the size of their seismic source persist as a fundamental challenge, despite scientific progress towards characterizing these events in real time. © 2015 The Author(s).

    2014-12-01

    Software Defined Radio/Radar (SDR) platforms have become increasingly popular as researchers, hobbyists, and military seek more efficient and cost-effective means for radar construction and operation. SDR platforms, by definition, utilize a software-based interface for configuration in contrast to traditional, hard-wired platforms. In an effort to provide new and improved radar sensing capabilities, Penn State has been developing advanced instruments and technologies for future radars, with primary objectives of making such instruments more capable, portable, and more cost effective. This paper will describe the design and implementation of two low-cost radar systems and their deployment in ionospheric research at both low and mid-latitudes. One radar has been installed near Penn State campus, University Park, Pennsylvania (77.97°W, 40.70°N), to make continuous meteor observations and mid-latitude plasma irregularities. The second radar is being installed in Huancayo (12.05°S, -75.33°E), Peru, which is capable of detecting E and F region plasma irregularities as well as meteor reflections. In this paper, we examine and compare the diurnal and seasonal variability of specular, non- specular, and head-echoes collected with these two new radar systems and discuss sampling biases of each meteor observation technique. We report our current efforts to validate and calibrate these radar systems with other VHF radars such as Jicamarca and SOUSY. We also present the general characteristics of continuous measurements of E-region and F-region coherent echoes using these modern radar systems and compare them with coherent radar events observed at other geographic mid-latitude radar stations.

    The Soil Moisture Active Passive (SMAP) mission launched on Jan 31, 2015. The mission employs L-band radar and radiometer measurements to estimate soil moisture with 4% volumetric accuracy at a resolution of 10 km, and freeze-thaw state at a resolution of 1-3 km. Immediately following launch, there was a three month instrument checkout period, followed by six months of level 1 (L1) calibration and validation. In this presentation, we will discuss the calibration and validation activities and results for the L1 radar data. Early SMAP radar data were used to check commanded timing parameters, and to work out issues in the low- and high-resolution radar processors. From April 3-13 the radar collected receive only mode data to conduct a survey of RFI sources. Analysis of the RFI environment led to a preferred operating frequency. The RFI survey data were also used to validate noise subtraction and scaling operations in the radar processors. Normal radar operations resumed on April 13. All radar data were examined closely for image quality and calibration issues which led to improvements in the radar data products for the beta release at the end of July. Radar data were used to determine and correct for small biases in the reported spacecraft attitude. Geo-location was validated against coastline positions and the known positions of corner reflectors. Residual errors at the time of the beta release are about 350 m. Intra-swath biases in the high-resolution backscatter images are reduced to less than 0.3 dB for all polarizations. Radiometric cross-calibration with Aquarius was performed using areas of the Amazon rain forest. Cross-calibration was also examined using ocean data from the low-resolution processor and comparing with the Aquarius wind model function. Using all a-priori calibration constants provided good results with co-polarized measurements matching to better than 1 dB, and cross-polarized measurements matching to about 1 dB in the beta release.

    A new solid-state radar switchboard equipped with 16 input ports which will output data to 16 displays is presented. Each of the ports will handle a single two-dimensional radar input, or three ports will accommodate a three-dimensional radar input. A video switch card of the switchboard is used to switch all signals, with the exception of the IFF-mode-control lines. Each card accepts inputs from up to 16 sources and can pass a signal with bandwidth greater than 20 MHz to the display assigned to that card. The synchro amplifier of current systems has been eliminated and in the new design each PPI receives radar data via a single coaxial cable. This significant reduction in cabling is achieved by adding a serial-to-parallel interface and a digital-to-synchro converter located at the PPI.

    2013-06-01

    Full Text Available En Allemagne, en 1999, le Chancelier fédéral et son gouvernement ont quitté Bonn pour Berlin. Ce transfert du pouvoir est accompagné de celui d’une grande partie de l’appareil d’État et de la haute administration, et des fonctions qui leur sont traditionnellement attribuées comme la presse, les lobbys ou encore la diplomatie. Le déplacement du statut de capitale effective de l’Allemagne de Bonn à Berlin est le résultat des évolutions géopolitiques d’un pays ayant recouvré son unité et sa pleine et entière souveraineté. Installer le pouvoir exécutif et législatif à Berlin était une démarche hautement symbolique, visant à normaliser la position de l’ancienne capitale de la RDA et du IIIe Reich comme véritable centre politique de l’Allemagne. Or le déplacement des institutions fédérales n’est pas qu’un acte symbolique. Il entraîne également à l’échelle intra-urbaine des dynamiques très concrètes sur le tissu urbain et participe à la mise en place de nouvelles centralités dans la ville. En effet, le statut de capitale d’État prédestine l’agglomération à la coprésence de nombreuses fonctions urbaines spécifiques plus ou moins directement liées à l’exercice ou à la symbolique du pouvoir.

The typhoon center passed about 80 km southeast from the radar site. Mesoscale precipitating clouds developed due to warm-moist airmass transport from the typhoon, and passed over the MU radar site with easterly or southeasterly winds. We primarily present the wind behaviour including the vertical component which a conventional meteorological Doppler radar cannot directly observe, and discuss the relationship between the wind behaviour of the typhoon and the precipitating system. To investigate the dynamic structure of the typhoon, the observed wind was divided into radial and tangential wind components under the assumption that the typhoon had an axi-symmetric structure. Altitude range of outflow ascended from 1–3 km to 2–10 km with increasing distance (within 80–260 km range from the typhoon center, and in-flow was observed above and below the outflow. Outflow and inflow were associated with updraft and downdraft, respectively. In the tangential wind, the maximum speed of counterclockwise winds was confirmed at 1–2 km altitudes. Based on the vertical velocity and the reflectivity obtained with the MU radar and the C-band meteorological radar, respectively, precipitating clouds, accompanied by the wind behaviour of the typhoon, were classified into stratiform and convective precipitating clouds. In the stratiform precipitating clouds, a vertical shear of radial wind and the maximum speed of counterclockwise wind were observed. There was a strong reflectivity layer called a ‘bright band’ around the 4.2 km altitude. We confirmed strong updrafts and down-drafts below and above it, respectively, and the existence of a relatively dry layer around the bright band level from radiosonde

    Some of the radar altimetry profiles of Mercury obtained on the basis of data from the Arecibo Observatory are presented. In these measurements, the delay-Doppler method was used to measure altitudes along the Doppler equator, rather than to map radar reflectivity. The profiles, derived from observations made over a 6-yr period, provide extensive coverage over a restricted equatorial band and permit the identification of radar signatures for features as small as 50-km diameter craters and 1-km-high arcuate scarps. The data allowed identification of large-scale topographic features such as smooth plains subsidence zones and major highland regions

    The underground radar exploration is adopted to surveys of cavity under the road and buried pipes since the result of high resolution is obtained. However, the explorative depth of the radar is shallow, 2-3m in soil basement, and its applicable field has been limited. The continuous wave radar (FM-CW radar) was devised to get deeper explorative depth, but has been used for the geological structure survey such as the fault survey since it is lower in resolution as compared with the pulse radar. Therefore, to make use of characteristics of the continuous wave radar and enhance resolution in the shallow part, an experiment on buried pipes was conducted for the purpose of assessing and improving the FM-CW radar. In this processing, the wave form treatment used in the reflection method seismic survey was adopted for the radar survey. There are some problems, but it is effective to adopt the same algorithm to that used in the seismic survey to the radar exploration. The explorative depth was discussed from the damping rate of electromagnetic waves and dynamic range of facilities of the experimental site, and 7m was obtained. 5 figs., 1 tab.

    We investigate the possibility of detecting extensive air showers by the radar technique. Considering a bistatic radar system and different shower geometries, we simulate reflection of radio waves off the static plasma produced by the shower in the air. Using the Thomson cross-section for radio wave reflection, we obtain the time evolution of the signal received by the antennas. The frequency upshift of the radar echo and the power received are studied to verify the feasibility of the radar detection technique.

    Aggregating multiple non-expert opinions into a collective estimate can improve accuracy across many contexts. However, two sources of error can diminish collective wisdom: individual estimation biases and information sharing between individuals. Here, we measure individual biases and social influence rules in multiple experiments involving hundreds of individuals performing a classic numerosity estimation task. We first investigate how existing aggregation methods, such as calculating the arithmetic mean or the median, are influenced by these sources of error. We show that the mean tends to overestimate, and the median underestimate, the true value for a wide range of numerosities. Quantifying estimation bias, and mapping individual bias to collective bias, allows us to develop and validate three new aggregation measures that effectively counter sources of collective estimation error. In addition, we present results from a further experiment that quantifies the social influence rules that individuals employ when incorporating personal estimates with social information. We show that the corrected mean is remarkably robust to social influence, retaining high accuracy in the presence or absence of social influence, across numerosities and across different methods for averaging social information. Using knowledge of estimation biases and social influence rules may therefore be an inexpensive and general strategy to improve the wisdom of crowds. © 2018 The Author(s).

  2. Investigations on the sensitivity of a stepped-frequency radar utilizing a vector network analyzer for Ground Penetrating Radar

    Seyfried, Daniel; Schubert, Karsten; Schoebel, Joerg

    2014-12-01

    Employing a continuous-wave radar system, with the stepped-frequency radar being one type of this class, all reflections from the environment are present continuously and simultaneously at the receiver. Utilizing such a radar system for Ground Penetrating Radar purposes, antenna cross-talk and ground bounce reflection form an overall dominant signal contribution while reflections from objects buried in the ground are of quite weak amplitude due to attenuation in the ground. This requires a large dynamic range of the receiver which in turn requires high sensitivity of the radar system. In this paper we analyze the sensitivity of our vector network analyzer utilized as stepped-frequency radar system for GPR pipe detection. We furthermore investigate the performance of increasing the sensitivity of the radar by means of appropriate averaging and low-noise pre-amplification of the received signal. It turns out that the improvement in sensitivity actually achievable may differ significantly from theoretical expectations. In addition, we give a descriptive explanation why our appropriate experiments demonstrate that the sensitivity of the receiver is independent of the distance between the target object and the source of dominant signal contribution. Finally, our investigations presented in this paper lead to a preferred setting of operation for our vector network analyzer in order to achieve best detection capability for weak reflection amplitudes, hence making the radar system applicable for Ground Penetrating Radar purposes.

    The European Incoherent Scatter Radar in the Auroral Zone (EISCAT) is an intereuropean organization planning to install an incoherent scatter radar system in Northern Scandinavia. It is supported by Finland, France, Norway, Great Britain, Sweden and West Germany, and its headquarters is in Kiruna, Sweden. The radar is planned to be operating in 1979. In order to introduce students and young scientists to the incoherent scatter radar technique, a summer school was held in Tromsoe, from 5th to 13th June 1975. In these proceedings an introduction to the basic theory of fluctuations in a plasma is given. Some of the present incoherent scatter radars now in use are presented and special considerations with respect to the planned EISACT facility are discussed. Reviews of some recent results and scientific problems relevant to EISCAT are also presented and finally a presentation of some observational techniques complementary to incoherent scatter radars is included.

    Full Text Available The article deals with the notion of ars Dei (“art of God” in philosophical and theological thought of St. Augustine of Hippo. It is argued that ars Dei is not only an intelligent design or knowledge which God had with regard to his creation, but also the divine Wisdom and Word of God, in whom exist the eternal and unchangeable forms and reasons of all things, according to which God not only knows, but also creates everything. It is notified, that the notion of ars Dei reflects the Neo-Platonic notion of the universal Intellect (νοDς and also has an affi nity with the concept of the universal Logos, or “designing Logos” (τεχνικOς λMγος, as found in the works of Philo and in those of several Greek Fathers of the Church, as well as is a result of a development of the biblical notions of the Wisdom and Word of God, through whom all things were made. In the same time Augustine’s doctrine is truly without peer in contemporary philosophical and Patristic literature.

    Lerner, E. J.

    1985-02-01

    The problems encountered by laser and IR homing devices for guided munitions may be tractable with warhead-mounted mm-wave radars. Operating at about 100 GHz and having several kilometers range, mm-wave radars see through darkness, fog, rain and smoke. The radar must be coupled with an analyzer that discerns moving and stationary targets and higher priority targets. The target lock-on can include shut-off of the transmitter and reception of naturally-generated mm-waves bouncing off the target when in the terminal phase of the flight. Monopulse transmitters have simplified the radar design, although mass production of finline small radar units has yet to be accomplished, particularly in combining GaAs, ferrites and other materials on one monolithic chip.

  16. HF Radar Sea-echo from Shallow Water

    Directory of Open Access Journals (Sweden)

    Josh Kohut

    2008-08-01

    Full Text Available HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar echo is strongest. In this paper, we treat the situation when the radar echo is returned from ocean waves that interact with the ocean floor. Simulations are described which demonstrate the effect of shallow water on radar sea-echo. These are used to investigate limits on the existing theory and to define water depths at which shallow-water effects become significant. The second-order spectral energy increases relative to the first-order as the water depth decreases, resulting in spectral saturation when the waveheight exceeds a limit defined by the radar transmit frequency. This effect is particularly marked for lower radar transmit frequencies. The saturation limit on waveheight is less for shallow water. Shallow water affects second-order spectra (which gives wave information far more than first-order (which gives information on current velocities, the latter being significantly affected only for the lowest radar transmit frequencies for extremely shallow water. We describe analysis of radar echo from shallow water measured by a Rutgers University HF radar system to give ocean wave spectral estimates. Radar-derived wave height, period and direction are compared with simultaneous shallow-water in-situ measurements.

  20. 5 year radar-based rainfall statistics: disturbances analysis and development of a post-correction scheme for the German radar composite

    Science.gov (United States)

    Wagner, A.; Seltmann, J.; Kunstmann, H.

    2015-02-01

    A radar-based rainfall statistic demands high quality data that provide realistic precipitation amounts in space and time. Instead of correcting single radar images, we developed a post-correction scheme for long-term composite radar data that corrects corrupted areas, but preserves the original precipitation patterns. The post-correction scheme is based on a 5 year statistical analysis of radar composite data and its constituents. The accumulation of radar images reveals artificial effects that are not visible in the individual radar images. Some of them are already inherent to single radar data such as the effect of increasing beam height, beam blockage or clutter remnants. More artificial effects are introduced in the process of compositing such as sharp gradients at the boundaries of overlapping areas due to different beam heights and resolution. The cause of these disturbances, their behaviour with respect to reflectivity level, season or altitude is analysed based on time-series of two radar products: the single radar reflectivity product PX for each of the 16 radar systems of the German Meteorological Service (DWD) for the time span 2000 to 2006 and the radar composite product RX of DWD from 2005 through to 2009. These statistics result in additional quality information on radar data that is not available elsewhere. The resulting robust characteristics of disturbances, e.g. the dependency of the frequencies of occurrence of radar reflectivities on beam height, are then used as a basis for the post-correction algorithm. The scheme comprises corrections for shading effects and speckles, such as clutter remnants or overfiltering, as well as for systematic differences in frequencies of occurrence of radar reflectivities between the near and the far ranges of individual radar sites. An adjustment to rain gauges is also included. Applying this correction, the Root-Mean-Square-Error for the comparison of radar derived annual rain amounts with rain gauge data

  1. Low-Cost Mini Radar: Design Prototyping and Tests

    Directory of Open Access Journals (Sweden)

    Dario Tarchi

    2017-01-01

    Full Text Available Radar systems are largely employed for surveillance of wide and remote areas; the recent advent of drones gives the opportunity to exploit radar sensors on board of unmanned aerial platforms. Nevertheless, whereas drone radars are currently available for military applications, their employment in the civilian domain is still limited. The present research focuses on design, prototyping, and testing of an agile, low-cost, mini radar system, to be carried on board of Remotely Piloted Aircraft (RPAs or tethered aerostats. In particular, the paper faces the challenge to integrate the in-house developed radar sensor with a low-cost navigation board, which is used to estimate attitude and positioning data. In fact, a suitable synchronization between radar and navigation data is essential to properly reconstruct the radar picture whenever the platform is moving or the radar is scanning different azimuthal sectors. Preliminary results, relative to tests conducted in preoperational conditions, are provided and exploited to assert the suitable consistency of the obtained radar pictures. From the results, there is a high consistency between the radar images and the picture of the current environment emerges; finally, the comparison of radar images obtained in different scans shows the stability of the platform.

  4. Radar efficiency and the calculation of decade-long PMSE backscatter cross-section for the Resolute Bay VHF radar

    Directory of Open Access Journals (Sweden)

    N. Swarnalingam

    2009-04-01

    Full Text Available The Resolute Bay VHF radar, located in Nunavut, Canada (75.0° N, 95.0° W and operating at 51.5 MHz, has been used to investigate Polar Mesosphere Summer Echoes (PMSE since 1997. PMSE are a unique form of strong coherent radar echoes, and their understanding has been a challenge to the scientific community since their discovery more than three decades ago. While other high latitude radars have recorded strong levels of PMSE activities, the Resolute Bay radar has observed relatively lower levels of PMSE strengths. In order to derive absolute measurements of PMSE strength at this site, a technique is developed to determine the radar efficiency using cosmic (sky noise variations along with the help of a calibrated noise source. VHF radars are only rarely calibrated, but determination of efficiency is even less common. Here we emphasize the importance of efficiency for determination of cross-section measurements. The significant advantage of this method is that it can be directly applied to any MST radar system anywhere in the world as long as the sky noise variations are known. The radar efficiencies for two on-site radars at Resolute Bay are determined. PMSE backscatter cross-section is estimated, and decade-long PMSE strength variations at this location are investigated. It was noticed that the median of the backscatter cross-section distribution remains relatively unchanged, but over the years a great level of variability occurs in the high power tail of the distribution.

    1995-01-01

    This report examines the possible degradations of radar performance that may be caused by the presence of a wind turbine generator within the radar coverage area. A brief literature survey reviews the previously published work, which is mainly concerned with degradation of broadcast TV reception. Estimates are made of wind turbine generator scattering cross-sections, and of the time and Doppler characteristics of the echo signals from representative wind turbine generator. The general characteristics of radar detection and tracking methods are described, and the behaviour of such systems in the presence of strong returns from a wind turbine generator (or an array of them) is discussed.

  8. New look at radar auroral motions

    During October 1974, three modifications were temporarily added to the NOAA radar auroral backscatter facility located at Anchorage, Alaska. These modifications included (1) a multiple azimuth antenna system. (2) an on-line computer for processing amplitude and mean Doppler profiles of the radar backscatter, and (3) a 13-baud Barker coder. In combination with the radar these modifications provided data relevant to understanding both the microscopic and the macroscopic nature of the radar aurora. Appreciable structure was often found in the Doppler velocity profiles of radar auroral irregularities. Doppler velocities of nearly 2000 m/s were observed. By combining scatter amplitude profiles and mean Doppler profiles from the five azimuths we have produced contour maps of the scatter intensity and the Doppler velocity. The scatter intensity maps often indicate appreciable temporal and spatial structure in the radar auroral irregularities, corroborating the results of Tsunoda et al. (1974). The mean Doppler contour maps indicate that there is also appreciable temporal and spatial structure in the flow velocities of radar auroral irregularities. At those times when there appears to be large-scale uniformity in the irregularity flow, the Doppler velocity varies with azimuth in a manner that is consistent with a cosine-dependent azimuthal variation

    The Comet Radar Explorer (CORE) is designed to perform a comprehensive and detailed exploration of the interior, surface, and inner coma structures of a scientifically impor-tant Jupiter family comet. These structures will be used to investigate the origins of cometary nuclei, their physical and geological evolution, and the mechanisms driving their spectacular activity. CORE is a high heritage spacecraft, injected by solar electric propulsion into orbit around a comet. It is capable of coherent deep radar imaging at decameter wavelengths, high resolution stereo color imaging, and near-IR imaging spectroscopy. Its primary objective is to obtain a high-resolution map of the interior structure of a comet nucleus at a resolution of ¿100 elements across the diameter. This structure shall be related to the surface geology and morphology, and to the structural details of the coma proximal to the nucleus. This is an ideal complement to the science from recent comet missions, providing insight into how comets work. Knowing the structure of the interior of a comet-what's inside-and how cometary activity works, is required before we can understand the requirements for a cryogenic sample return mission. But more than that, CORE is fundamental to understanding the origin of comets and their evolution in time. The mission is made feasible at low cost by the use of now-standard MARSIS-SHARAD reflec-tion radar imaging hardware and data processing, together with proven flight heritage of solar electric propulsion. Radar flight heritage has been demonstrated by the MARSIS radar on Mars Express (Picardi et al., Science 2005; Plaut et al., Science 2007), the SHARAD radar onboard the Mars Reconnaissance Orbiter (Seu et al., JGR 2007), and the LRS radar onboard Kaguya (Ono et al, EPS 2007). These instruments have discovered detailed subsurface structure to depths of several kilometers in a variety of terrains on Mars and the Moon. A reflection radar deployed in orbit about a comet

    2015-12-01

    By providing high-resolution quantitative precipitation information (QPI), weather radars have revolutionized hydrology in the last two decades. With the aid of GIS technology, radar-based quantitative precipitation estimates (QPE) have enabled routine high-resolution hydrologic modeling in many parts of the world. Given the ever-increasing need for higher-resolution hydrologic and water resources information for a wide range of applications, one may expect that the use of weather radar will only grow. Despite the tremendous progress, a number of significant scientific, technological and engineering challenges remain to realize its potential. New challenges are also emerging as new areas of applications are discovered, explored and pursued. The purpose of this special issue is to provide the readership with some of the latest advances, lessons learned, experiences gained, and science issues and challenges related to hydrologic applications of weather radar. The special issue features 20 contributions on various topics which reflect the increasing diversity as well as the areas of focus in radar hydrology today. The contributions may be grouped as follows:

  12. Classification of radar echoes using fractal geometry

    International Nuclear Information System (INIS)

    Azzaz, Nafissa; Haddad, Boualem

    2017-01-01

    Highlights: • Implementation of two concepts of fractal geometry to classify two types of meteorological radar echoes. • A new approach, called a multi-scale fractal dimension is used for classification between fixed echoes and rain echoes. • An Automatic identification system of meteorological radar echoes was proposed using fractal geometry. - Abstract: This paper deals with the discrimination between the precipitation echoes and the ground echoes in meteorological radar images using fractal geometry. This study aims to improve the measurement of precipitations by weather radars. For this, we considered three radar sites: Bordeaux (France), Dakar (Senegal) and Me lbourne (USA). We showed that the fractal dimension based on contourlet and the fractal lacunarity are pertinent to discriminate between ground and precipitation echoes. We also demonstrated that the ground echoes have a multifractal structure but the precipitations are more homogeneous than ground echoes whatever the prevailing climate. Thereby, we developed an automatic classification system of radar using a graphic interface. This interface, based on the fractal geometry makes possible the identification of radar echoes type in real time. This system can be inserted in weather radar for the improvement of precipitation estimations.

    2018-05-01

    This study is aimed to find out the type of threats of pottery as a local wisdom of Sitiwinangun Village. The study used qualitative approach which included observation, interviews, direct involvement and literature study as technique to collect the data. The data was analyzed by descriptive exploratory analysis. The finding results showed that the production of Sitiwinangun pottery, in the technique and motifs, were still produced according to the ancestors. Pottery has a closed-relationship to agrarian culture of Sitiwinangun's society. In cultivating season, the soil was used not only used to cultivate rice and palawija (crops planted as second crop in dry season) but it was also used to dig a layer of soil as the raw material of pottery. There were some potential threats on Sitiwinangun Pottery such as a reduction in raw material because of the land-settlement, slow regeneration, and consumers' preferred on household appliance made of plastic. Nevertheless, it never decreases the spirit of Sitiwinangun society to maintain the pottery as their local wisdom. They keep on their principle that the nature gives the value on their life and the value is an ancestral heritage that must be maintained in modern era in order to preserve the environment. Furthermore, the most important is that pottery is not only made as the functional object for human activity but it is made as the local knowledge of Sitiwinagun that very allows to be learnt intact and sustainable.

    2015-07-01

    Radar network can offer significant performance improvement for target detection and information extraction employing spatial diversity. For a fixed number of radars, the achievable mutual information (MI) for estimating the target parameters may extend beyond a predefined threshold with full power transmission. In this paper, an effective low probability of intercept (LPI) optimisation algorithm is presented to improve LPI performance for radar network. Based on radar network system model, we first provide Schleher intercept factor for radar network as an optimisation metric for LPI performance. Then, a novel LPI optimisation algorithm is presented, where for a predefined MI threshold, Schleher intercept factor for radar network is minimised by optimising the transmission power allocation among radars in the network such that the enhanced LPI performance for radar network can be achieved. The genetic algorithm based on nonlinear programming (GA-NP) is employed to solve the resulting nonconvex and nonlinear optimisation problem. Some simulations demonstrate that the proposed algorithm is valuable and effective to improve the LPI performance for radar network.

    Radar ISR does not always involve cooperative or even friendly targets. An adversary has numerous techniques available to him to counter the effectiveness of a radar ISR sensor. These generally fall under the banner of jamming, spoofing, or otherwise interfering with the EM signals required by the radar sensor. Consequently mitigation techniques are prudent to retain efficacy of the radar sensor. We discuss in general terms a number of mitigation techniques.

    The unmanned airborne (UAV) laser spectrum radar has played a leading role in remote sensing because the transmitter and the receiver are together at laser spectrum radar. The advantages of the integrated transceiver laser spectrum radar is that it can be used in the oil and gas pipeline leak detection patrol line which needs the non-contact reflective detection. The UAV laser spectrum radar can patrol the line and specially detect the swept the area are now in no man's land because most of the oil and gas pipelines are in no man's land. It can save labor costs compared to the manned aircraft and ensure the safety of the pilots. The UAV laser spectrum radar can be also applied in the post disaster relief which detects the gas composition before the firefighters entering the scene of the rescue.

Pour cela, nous allons d'abord définir le P2P, décrire en bref ces manifestations, et le différencier d'autres modalités d'échange intersubjectif tel que le marché, la hiérarchie, l'économie du don.Comme principale modalité P2P nous distinguons: Les processus de production P2P, comme troisième mode de production, qui n'est ni géré par un mode hiérarchique ou par l'état, ni répondant à des impératifs de profit ou qui sont modulés par le biais des prix. Les processus de gouvernance P2P, qui gouverne ces processus de production. Les formes de propriété P2P, qui sont destine a empecher l’appropriation prive de cette production pour le commun.Afin d’examiner les characteristiques de cette nouvelle dynamique sociale, nous utilisons la typologie intersubjective de l’anthropologue Alan Page Fisque, qui distingue: 1. l'échange égalitaire (Equality Matching, c..a.d l’economie du don. 2.

  11. Using phase for radar scatterer classification

    Science.gov (United States)

    Moore, Linda J.; Rigling, Brian D.; Penno, Robert P.; Zelnio, Edmund G.

    2017-04-01

    Traditional synthetic aperture radar (SAR) systems tend to discard phase information of formed complex radar imagery prior to automatic target recognition (ATR). This practice has historically been driven by available hardware storage, processing capabilities, and data link capacity. Recent advances in high performance computing (HPC) have enabled extremely dense storage and processing solutions. Therefore, previous motives for discarding radar phase information in ATR applications have been mitigated. First, we characterize the value of phase in one-dimensional (1-D) radar range profiles with respect to the ability to correctly estimate target features, which are currently employed in ATR algorithms for target discrimination. These features correspond to physical characteristics of targets through radio frequency (RF) scattering phenomenology. Physics-based electromagnetic scattering models developed from the geometrical theory of diffraction are utilized for the information analysis presented here. Information is quantified by the error of target parameter estimates from noisy radar signals when phase is either retained or discarded. Operating conditions (OCs) of signal-tonoise ratio (SNR) and bandwidth are considered. Second, we investigate the value of phase in 1-D radar returns with respect to the ability to correctly classify canonical targets. Classification performance is evaluated via logistic regression for three targets (sphere, plate, tophat). Phase information is demonstrated to improve radar target classification rates, particularly at low SNRs and low bandwidths.

  12. Pedestrian recognition using automotive radar sensors

    2012-09-01

    The application of modern series production automotive radar sensors to pedestrian recognition is an important topic in research on future driver assistance systems. The aim of this paper is to understand the potential and limits of such sensors in pedestrian recognition. This knowledge could be used to develop next generation radar sensors with improved pedestrian recognition capabilities. A new raw radar data signal processing algorithm is proposed that allows deep insights into the object classification process. The impact of raw radar data properties can be directly observed in every layer of the classification system by avoiding machine learning and tracking. This gives information on the limiting factors of raw radar data in terms of classification decision making. To accomplish the very challenging distinction between pedestrians and static objects, five significant and stable object features from the spatial distribution and Doppler information are found. Experimental results with data from a 77 GHz automotive radar sensor show that over 95% of pedestrians can be classified correctly under optimal conditions, which is compareable to modern machine learning systems. The impact of the pedestrian's direction of movement, occlusion, antenna beam elevation angle, linear vehicle movement, and other factors are investigated and discussed. The results show that under real life conditions, radar only based pedestrian recognition is limited due to insufficient Doppler frequency and spatial resolution as well as antenna side lobe effects.

Subsequently, the ORCS is defined in analogy to classical radar cross section (RCS. The unique features of the incident OAM-carrying field are analyzed. The scattered field is derived, and the analytical expressions of ORCSs for metal plate and cylinder targets are obtained. Furthermore, the ORCS and RCS are compared to illustrate the influences of OAM mode number, target size and signal frequency on the ORCS. Analytical studies demonstrate that the mirror-reflection phenomenon disappears and peak values of ORCS are in the non-specular direction. Finally, the ORCS features are summarized to show its advantages in radar target detection. This work can provide theoretical guidance to the design of OAM-based radar as well as the target detection and identification applications.

    The Cassini Radar's synthetic aperture radar (SAR) ambiguity analysis is unique with respect to other spaceborne SAR ambiguity analyses owing to the non-orbiting spacecraft trajectory, asymmetric antenna pattern, and burst mode of data collection. By properly varying the pointing, burst mode timing, and radar parameters along the trajectory this study shows that the signal-to-ambiguity ratio of better than 15 dB can be achieved for all images obtained by the Cassini Radar.

    The fields of radar polarimetry and optical polarimetry are compared. The mathematics of optic polarimetry are formulated such that a local right handed coordinate system is always used to describe the polarization states. This is not done in radar polarimetry. Radar optimum polarization theory is redeveloped within the framework of optical polarimetry. The radar optimum polarizations and optic eigenvalues of common scatterers are compared. In addition a novel definition of an eigenpolarization state is given and the accompanying mathematics is developed. The polarization response calculated using optic, radar and novel definitions is presented for a variety of scatterers. Polarimetric transformation provides a means to characterize scatters in more than one polarization basis. Polarimetric transformation for an ensemble of scatters is obtained via two methods: (1) the covariance method and (2) the instantaneous scattering matrix (ISM) method. The covariance method is used to relate the mean radar parameters of a +/-45^circ linear polarization basis to those of a horizontal and vertical polarization basis. In contrast the ISM method transforms the individual time samples. Algorithms are developed for transforming the time series from fully polarimetric radars that switch between orthogonal states. The transformed time series are then used to calculate the mean radar parameters of interest. It is also shown that propagation effects do not need to be removed from the ISM's before transformation. The techniques are demonstrated using data collected by POLDIRAD, the German Aerospace Research Establishment's fully polarimetric C-band radar. The differential phase observed between two copolar states, Psi_{CO}, is composed of two phases: (1) differential propagation phase, phi_{DP}, and (2) differential backscatter phase, delta. The slope of phi_{DP } with range is an estimate of the specific differential phase, K_{DP}. The process of estimating K_{DP} is complicated when

    We developed a compact radar for use on a small UAV to conduct measurements over the ice sheets in Greenland and Antarctica. It operates at center frequencies of 14 and 35 MHz with bandwidths of 1 MHz and 4 MHz, respectively. The radar weighs about 2 kgs and is housed in a box with dimensions of 20.3 cm x 15.2 cm x 13.2 cm. It transmits a signal power of 100 W at a pulse repletion frequency of 10 kHz and requires average power of about 20 W. The antennas for operating the radar are integrated into the wings and airframe of a small UAV with a wingspan of 5.3 m. We selected the frequencies of 14 and 35 MHz based on previous successful soundings of temperate ice in Alaska with a 12.5 MHz impulse radar [Arcone, 2002] and temperate glaciers in Patagonia with a 30 MHz monocycle radar [Blindow et al., 2012]. We developed the radar-equipped UAV to perform surveys over a 2-D grid, which allows us to synthesize a large two-dimensional aperture and obtain fine resolution in both the along- and cross-track directions. Low-frequency, high-sensitivity radars with 2-D aperture synthesis capability are needed to overcome the surface and volume scatter that masks weak echoes from the ice-bed interface of fast-flowing glaciers. We collected data with the radar-equipped UAV on sub-glacial ice near Lake Whillans at both 14 and 35 MHz. We acquired data to evaluate the concept of 2-D aperture synthesis and successfully demonstrated the first successful sounding of ice with a radar on an UAV. We are planning to build multiple radar-equipped UAVs for collecting fine-resolution data near the grounding lines of fast-flowing glaciers. In this presentation we will provide a brief overview of the radar and UAV, as well as present results obtained at both 14 and 35 MHz. Arcone, S. 2002.

    Full Text Available Dans le sport français, le fédéralisme s’est installé comme une évidence institutionnelle dès la fin du 19e siècle et le début du 20e siècle dans un pays qui pourtant ne se pense pas fédéral. En outre, si son apparition est liée à l’émergence du sport comme nouvelle pratique sociale à côté d’autres pratiques physiques plus traditionnelles, il s’est rapidement imposé comme la pierre angulaire de l’ordre sportif français. Près d’un siècle plus tard, son monopole institutionnel est bousculé voire «concurrencé». Ces constats d’ensemble nous amènent à nous interroger sur les raisons pour lesquelles le sport a épousé le modèle fédéral dans un pays non fédéral, mais aussi sur ses limites actuelles. Est-il encore le modèle approprié aux circonstances contemporaines ? A-t-il toujours sa place dans le système de gouvernance du sport ? Ou bien, a contrario, reste-t-il le dernier rempart légitime face aux excès du sport contemporain (dopage, violence, corruptions, déficits… ? À partir d’une approche socio-historique, il s’est agi dans cet article de reconstruire le fil de la généalogie du fédéralisme sportif tout en s’interrogeant sur ses perspectives. Au delà de la question du fédéralisme, c’est bien celle de la gouvernance du sport contemporain qui est posée.

    The data-information-knowledge-wisdom (DIKW) model has been widely adopted in nursing informatics. In this article, we examine the evolution of DIKW in nursing informatics while incorporating critiques from other disciplines. This includes examination of assumptions of linearity and hierarchy and an exploration of the implicit philosophical grounding of the model. Two guiding questions are considered: (1) Does DIKW serve clinical information systems, nurses, or both? and (2) What level of theory does DIKW occupy? The DIKW model has been valuable in advancing the independent field of nursing informatics. We offer that if the model is to continue to move forward, its role and functions must be explicitly addressed.

    2010-01-01

    This software enables easy comparison of ground- and space-based radar observations. The software was initially designed to compare ground radar reflectivity from operational, ground based Sand C-band meteorological radars with comparable measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite s Precipitation Radar (PR) instrument. The software is also applicable to other ground-based and space-based radars. The ground and space radar volume matching and comparison software was developed in response to requirements defined by the Ground Validation System (GVS) of Goddard s Global Precipitation Mission (GPM) project. This software innovation is specifically concerned with simplifying the comparison of ground- and spacebased radar measurements for the purpose of GPM algorithm and data product validation. This software is unique in that it provides an operational environment to routinely create comparison products, and uses a direct geometric approach to derive common volumes of space- and ground-based radar data. In this approach, spatially coincident volumes are defined by the intersection of individual space-based Precipitation Radar rays with the each of the conical elevation sweeps of the ground radar. Thus, the resampled volume elements of the space and ground radar reflectivity can be directly compared to one another.

    Nowadays, myths and superstitions are present in spite of scientific and technological developments, especially when trying to solve problems that escape human understanding. This study was aimed at determining the existence of superstitions and myths in the university community, investigating their origins, influences, adoption and credibility, correlating them with people's level of knowledge. It is a descriptive/analytical research conducted at Teaching Units in the Area of Health of the Federal University of Goiás. The technique of content analysis was utilized for data analysis. Two categories have been created: Personal Attitudes related to Superstitions and Influences and Destruction of Superstitions. It was found out that there is a clash between popular and scientific knowledge, either leading to the exclusion of popular wisdom, to its 'veiled' maintenance, or even to an alliance between the two types of knowledge.

    A review of the experimental and theoretical background to the Condor equatorial electrojet compaign is followed by the presentation and discussion of VHF radar interferometer and HF radar backscatter data taken concurrently with two rocket in situ experiments reported in companion papers (Pfaff et al., this issue (a, b). Both experiments were conducted in strongly driven periods with the on-line radar interferometer displaying signatures of what has been interpreted in earlier radar work (Kudeki et al., 1982) as kilometer scale gradient drift waves. Low-frequency density fluctuations detected by in situ rocket sensors confirm the earlier interpretation. VHF radar/rocket data comparisons also indicate the existence of a turbulent layer in the upper portion of the daytime electrojet at about 108 km altitude driven purely by the two-stream instability. Nonlinear mode coupling of linearly growing two-stream waves to linearly damped 3-m vertical modes could account for the radar echoes scattered from this layer, which showed no indication of large-scale gradient drift waves. Nonlinear mode coupling may therefore compete with the wave-induced anomalous diffusion mechanism proposed recently by Sudan (1983) for the saturation of directly excited two-stream waves. Nighttime radar data show a bifurcated layer with the two parts having comparable echo strength but oppositely directed zonal drift velocities. The lower layer shows narrow backscatter spectra; the upper layer is characterized by kilometer scale waves and vertically propagating type 1 waves

    The Near-Earth Asteroid (NEA) population ranges in size from a few meters to more than 10 kilometers. NEAs have a wide variety of taxonomic classes, surface features, and shapes, including spheroids, binary objects, contact binaries, elongated, as well as irregular bodies. Using the Arecibo Observatory planetary radar system, we have measured apparent rotation rate, radar reflectivity, apparent diameter, and radar albedos for over 350 NEAs. The radar albedo is defined as the radar cross-section divided by the geometric cross-section. If a shape model is available, the actual cross-section is known at the time of the observation. Otherwise we derive a geometric cross-section from a measured diameter. When radar imaging is available, the diameter was measured from the apparent range depth. However, when radar imaging was not available, we used the continuous wave (CW) bandwidth radar measurements in conjunction with the period of the object. The CW bandwidth provides apparent rotation rate, which, given an independent rotation measurement, such as from lightcurves, constrains the size of the object. We assumed an equatorial view unless we knew the pole orientation, which gives a lower limit on the diameter. The CW also provides the polarization ratio, which is the ratio of the SC and OC cross-sections.We confirm the trend found by Benner et al. (2008) that taxonomic types E and V have very high polarization ratios. We have obtained a larger sample and can analyze additional trends with spin, size, rotation rate, taxonomic class, polarization ratio, and radar albedo to interpret the origin of the NEAs and their dynamical processes. The distribution of radar albedo and polarization ratio at the smallest diameters (≤50 m) differs from the distribution of larger objects (>50 m), although the sample size is limited. Additionally, we find more moderate radar albedos for the smallest NEAs when compared to those with diameters 50-150 m. We will present additional trends we

    Using radar and lidar data, the aim is to improve 3D rendering of terrain, including digital elevation models (DEM) and estimates of vegetation height and biomass in a variety of forest types and terrains. The 3D mapping of vegetation structure and the analysis are useful to determine the role of forest in climate change (carbon cycle), in providing habitat and as a provider of socio-economic services. This in turn will lead to potential for development of more effective land-use management. The first part of the project was to characterize the Shuttle Radar Topography Mission DEM error with respect to ICESat/GLAS point estimates of elevation. We investigated potential trends with latitude, canopy height, signal to noise ratio (SNR), number of LiDAR waveform peaks, and maximum peak width. Scatter plots were produced for each variable and were fitted with 1st and 2nd degree polynomials. Higher order trends were visually inspected through filtering with a mean and median filter. We also assessed trends in the DEM error variance. Finally, a map showing how DEM error was geographically distributed globally was created.

    Radar facies analysis provides a way of interpreting the large-scale structure of the subsurface from ground-penetrating radar (GPR) data. Radar facies are often distinguished from each other by the presence of patterns, such as flat-lying, dipping, or chaotic reflections, in different regions of a radar image. When these patterns can be associated with radar facies in a repeated and predictable manner we refer to them as `radar textures'. While it is often possible to qualitatively differentiate between radar textures visually, pattern recognition tools, like neural networks, require a quantitative measure to discriminate between them. We investigate whether currently available tools, such as instantaneous attributes or metrics adapted from standard texture analysis techniques, can be used to improve the classification of radar facies. To this end, we use a neural network to perform cross-validation tests that assess the efficacy of different textural measures for classifying radar facies in GPR data collected from the William River delta, Saskatchewan, Canada. We found that the highest classification accuracies (>93%) were obtained for measures of texture that preserve information about the spatial arrangement of reflections in the radar image, e.g., spatial covariance. Lower accuracy (87%) was obtained for classifications based directly on windows of amplitude data extracted from the radar image. Measures that did not account for the spatial arrangement of reflections in the image, e.g., instantaneous attributes and amplitude variance, yielded classification accuracies of less than 65%. Optimal classifications were obtained for textural measures that extracted sufficient information from the radar data to discriminate between radar facies but were insensitive to other facies specific characteristics. For example, the rotationally invariant Fourier-Mellin transform delivered better classification results than the spatial covariance because dip angle of the

  15. Forecasting elections with mere recognition from small, lousy samples: A comparison of collective recognition, wisdom of crowds, and representative polls

    Full Text Available We investigated the extent to which the human capacity for recognition helps to forecast political elections: We compared naive recognition-based election forecasts computed from convenience samples of citizens' recognition of party names to (i standard polling forecasts computed from representative samples of citizens' voting intentions, and to (ii simple---and typically very accurate---wisdom-of-crowds-forecasts computed from the same convenience samples of citizens' aggregated hunches about election results. Results from four major German elections show that mere recognition of party names forecast the parties' electoral success fairly well. Recognition-based forecasts were most competitive with the other models when forecasting the smaller parties' success and for small sample sizes. However, wisdom-of-crowds-forecasts outperformed recognition-based forecasts in most cases. It seems that wisdom-of-crowds-forecasts are able to draw on the benefits of recognition while at the same time avoiding its downsides, such as lack of discrimination among very famous parties or recognition caused by factors unrelated to electoral success. Yet it seems that a simple extension of the recognition-based forecasts---asking people what proportion of the population would recognize a party instead of whether they themselves recognize it---is also able to eliminate these downsides.

  16. Development Of Signal Detection For Radar Navigation System

    2017-09-01

    Full Text Available This paper aims to evaluate the performance of target detection in the presence of sea clutter. Radar detection of a background of unwanted clutter due to echoes from sea clutter or land is a problem of interest in the radar field. Radar detector has been developed by assuming the radar clutter is Gaussian distributed. However as technology emerges the radar distribution is seen to deviates from the Gaussian assumption. Thus detectors designs based on Gaussian assumption are no longer optimum for detection in non-Gaussian nature. The theory of target detection in Gaussian distributed clutter has been well established and the closed form of the detection performances can be easily obtained. However that is not the case in non-Gaussian clutter distributions. The operation of radar detection is determined by radar detection theory with different types of Swerling target models such as Swerling I II III IV and V. By using MATLAB these signal detection techniques are developed.

  19. Observation of snowfall with a low-power FM-CW K-band radar (Micro Rain Radar)

    Science.gov (United States)

    Kneifel, Stefan; Maahn, Maximilian; Peters, Gerhard; Simmer, Clemens

    2011-06-01

    Quantifying snowfall intensity especially under arctic conditions is a challenge because wind and snow drift deteriorate estimates obtained from both ground-based gauges and disdrometers. Ground-based remote sensing with active instruments might be a solution because they can measure well above drifting snow and do not suffer from flow distortions by the instrument. Clear disadvantages are, however, the dependency of e.g. radar returns on snow habit which might lead to similar large uncertainties. Moreover, high sensitivity radars are still far too costly to operate in a network and under harsh conditions. In this paper we compare returns from a low-cost, low-power vertically pointing FM-CW radar (Micro Rain Radar, MRR) operating at 24.1 GHz with returns from a 35.5 GHz cloud radar (MIRA36) for dry snowfall during a 6-month observation period at an Alpine station (Environmental Research Station Schneefernerhaus, UFS) at 2,650 m height above sea level. The goal was to quantify the potential and limitations of the MRR in relation to what is achievable by a cloud radar. The operational MRR procedures to derive standard radar variables like effective reflectivity factor ( Z e) or the mean Doppler velocity ( W) had to be modified for snowfall since the MRR was originally designed for rain observations. Since the radar returns from snowfall are weaker than from comparable rainfall, the behavior of the MRR close to its detection threshold has been analyzed and a method is proposed to quantify the noise level of the MRR based on clear sky observations. By converting the resulting MRR- Z e into 35.5 GHz equivalent Z e values, a remaining difference below 1 dBz with slightly higher values close to the noise threshold could be obtained. Due to the much higher sensitivity of MIRA36, the transition of the MRR from the true signal to noise can be observed, which agrees well with the independent clear sky noise estimate. The mean Doppler velocity differences between both radars

    2005-01-01

    The last decade of the evolution of radar was heavily influenced by the rapid increase in the information processing capabilities. Advances in solid state radio HF devices, digital technology, computing architectures and software offered the designers to develop very efficient radars. In designing modern radars the emphasis goes towards the simplification of the system hardware, reduction of overall power, which is compensated by coding and real time signal processing techniques. Radars are commonly employed in geophysical radio soundings like probing the ionosphere; stratosphere-mesosphere measurement, weather forecast, GPR and radio-glaciology etc. In the laboratorio di Geofisica Ambientale of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Rome, Italy, we developed two pulse compression radars. The first is a HF radar called AIS-INGV; Advanced Ionospheric Sounder designed both for the purpose of research and for routine service of the HF radio wave propagation forecast. The second is a VHF radar called GLACIORADAR, which will be substituting the high power envelope radar used by the Italian Glaciological group. This will be employed in studying the sub glacial structures of Antarctica, giving information about layering, the bed rock and sub glacial lakes if present. These are low power radars, which heavily rely on advanced hardware and powerful real time signal processing. Additional information is included in the original extended abstract.

  2. UAV-Borne Profiling Radar for Forest Research

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Microwave Radar is an attractive solution for forest mapping and inventories because microwave signals penetrates into the forest canopy and the backscattering signal can provide information regarding the whole forest structure. Satellite-borne and airborne imaging radars have been used in forest resources mapping for many decades. However, their accuracy with respect to the main forest inventory attributes substantially varies depending on the wavelength and techniques used in the estimation. Systems providing canopy backscatter as a function of canopy height are, practically speaking, missing. Therefore, there is a need for a radar system that would enable the scientific community to better understand the radar backscatter response from the forest canopy. Consequently, we undertook a research study to develop an unmanned aerial vehicle (UAV-borne profiling (i.e., waveform radar that could be used to improve the understanding of the radar backscatter response for forestry mapping and inventories. A frequency modulation continuous waveform (FMCW profiling radar, termed FGI-Tomoradar, was introduced, designed and tested. One goal is the total weight of the whole system is less than 7 kg, including the radar system and georeferencing system, with centimetre-level positioning accuracy. Achieving this weight goal would enable the FGI-Tomoradar system to be installed on the Mini-UAV platform. The prototype system had all four linear polarization measuring capabilities, with bistatic configuration in Ku-band. In system performance tests in this study, FGI-Tomoradar was mounted on a manned helicopter together with a Riegl VQ-480-U laser scanner and tested in several flight campaigns performed at the Evo site, Finland. Airborne laser scanning data was simultaneously collected to investigate the differences and similarities of the outputs for the same target area for better understanding the penetration of the microwave signal into the forest canopy

    Qu'est-ce que la matière ? Voilà une question à laquelle il pourrait sembler facile de répondre car il n'est rien de plus concret que la matière. Et pourtant, la réponse qu'en donne la physique contemporaine est pour le moins déconcertante ! Le concept-même de particules, briques élémentaires de la matière, s'est volatilisé, dissout dans des objets mathématiques abstraits et abscons pour les non-initiés. Plus nos théories sont précises et plus l'image qu'elles nous renvoient est insaisissable. En un siècle, la représentation des particules s'est métamorphosée en nuages de probabilité portés par des champs quantiques régis par des symétries confinées dans des espaces abstraits.

    Scheffer, Louis K.

    2014-01-01

    Interstellar radar is a potential intermediate step between passive observation of exoplanets and interstellar exploratory missions. Compared with passive observation, it has the traditional advantages of radar astronomy. It can measure surface characteristics, determine spin rates and axes, provide extremely accurate ranges, construct maps of planets, distinguish liquid from solid surfaces, find rings and moons, and penetrate clouds. It can do this even for planets close to the parent star. Compared with interstellar travel or probes, it also offers significant advantages. The technology required to build such a radar already exists, radar can return results within a human lifetime, and a single facility can investigate thousands of planetary systems. The cost, although too high for current implementation, is within the reach of Earth's economy.

    The Kyoto Meteor Radar is a monostatic coherent pulsed Doppler radar operating on the frequency of 31.57 MH. The system is computer controlled and uses radio interferometry for echo height determination. The antenna, an improvement, can be directed either to the north or the east. The system has been continuously collecting data on winds at meteor heights by radar observation. The meteor echo rate was also measured, the echo rate distribution with height and the daily variation in height integrated echo rate are discussed. Investigations of atmospheric tides are being pursued by cooperative observations. A novel approach to the study of gravity waves was attempted using the meteor radar which is able to detect the horizontal propagation of the waves by observing the changing phase through the region illuminated by the radar

    In this study, it was tested whether deep and shallow breathing has an effect on the cardiopulmonary radar cross-section (RCS). Continuous wave radar with quadrature architecture at 2.4GHz was used to test 2 human subjects breathing deep and shallow for 30 seconds each while seated 2 meters away from the radar. A retro-reflective marker was placed on the sternum of each subject and measured by infrared motion capture cameras to accurately track displacement of the chest. The quadrature radar outputs were processed to find the radius of the arc on the IQ plot using a circle-fitting algorithm. Results showed that the effective RCS ratio of deep to shallow breathing for subjects 1 and 2 was 6.99 and 2.24 respectively.

  17. Architecture for a 1-GHz Digital RADAR

    Mallik, Udayan

    2011-01-01

    An architecture for a Direct RF-digitization Type Digital Mode RADAR was developed at GSFC in 2008. Two variations of a basic architecture were developed for use on RADAR imaging missions using aircraft and spacecraft. Both systems can operate with a pulse repetition rate up to 10 MHz with 8 received RF samples per pulse repetition interval, or at up to 19 kHz with 4K received RF samples per pulse repetition interval. The first design describes a computer architecture for a Continuous Mode RADAR transceiver with a real-time signal processing and display architecture. The architecture can operate at a high pulse repetition rate without interruption for an infinite amount of time. The second design describes a smaller and less costly burst mode RADAR that can transceive high pulse repetition rate RF signals without interruption for up to 37 seconds. The burst-mode RADAR was designed to operate on an off-line signal processing paradigm. The temporal distribution of RF samples acquired and reported to the RADAR processor remains uniform and free of distortion in both proposed architectures. The majority of the RADAR's electronics is implemented in digital CMOS (complementary metal oxide semiconductor), and analog circuits are restricted to signal amplification operations and analog to digital conversion. An implementation of the proposed systems will create a 1-GHz, Direct RF-digitization Type, L-Band Digital RADAR--the highest band achievable for Nyquist Rate, Direct RF-digitization Systems that do not implement an electronic IF downsample stage (after the receiver signal amplification stage), using commercially available off-the-shelf integrated circuits.

    Stephen M. Wesson

    2004-01-01

    Full Text Available There are various quality problems associated with radar rainfall data viewed in images that include ground clutter, beam blocking and anomalous propagation, to name a few. To obtain the best rainfall estimate possible, techniques for removing ground clutter (non-meteorological echoes that influence radar data quality on 2-D radar rainfall image data sets are presented here. These techniques concentrate on repairing the images in both a computationally fast and accurate manner, and are nearest neighbour techniques of two sub-types: Individual Target and Border Tracing. The contaminated data is estimated through Kriging, considered the optimal technique for the spatial interpolation of Gaussian data, where the 'screening effect' that occurs with the Kriging weighting distribution around target points is exploited to ensure computational efficiency. Matrix rank reduction techniques in combination with Singular Value Decomposition (SVD are also suggested for finding an efficient solution to the Kriging Equations which can cope with near singular systems. Rainfall estimation at ground level from radar rainfall volume scan data is of interest and importance in earth bound applications such as hydrology and agriculture. As an extension of the above, Ordinary Kriging is applied to three-dimensional radar rainfall data to estimate rainfall rate at ground level. Keywords: ground clutter, data infilling, Ordinary Kriging, nearest neighbours, Singular Value Decomposition, border tracing, computation time, ground level rainfall estimation

    Texture is seen as an important spatial feature useful for identifying objects or regions of interest in an image. While textural features have been widely used in analyzing a variety of photographic images, they have not been used in processing radar images. A procedure for extracting a set of textural features for characterizing small areas in radar images is presented, and it is shown that these features can be used in classifying segments of radar images corresponding to different geological formations.

  4. Radar detection of ultra high energy cosmic rays

    Science.gov (United States)

    Myers, Isaac J.

    TARA (Telescope Array Radar) is a cosmic ray radar detection experiment co-located with Telescope Array, the conventional surface scintillation detector (SD) and fluorescence telescope detector (FD) near Delta, UT. The TARA detector combines a 40 kW transmitter and high gain transmitting antenna which broadcasts the radar carrier over the SD array and in the FD field of view to a 250 MS/s DAQ receiver. Data collection began in August, 2013. TARA stands apart from other cosmic ray radar experiments in that radar data is directly compared with conventional cosmic ray detector events. The transmitter is also directly controlled by TARA researchers. Waveforms from the FD-triggered data stream are time-matched with TA events and searched for signal using a novel signal search technique in which the expected (simulated) radar echo of a particular air shower is used as a matched filter template and compared to radio waveforms. This technique is used to calculate the radar cross-section (RCS) upper-limit on all triggers that correspond to well-reconstructed TA FD monocular events. Our lowest cosmic ray RCS upper-limit is 42 cm2 for an 11 EeV event. An introduction to cosmic rays is presented with the evolution of detection and the necessity of new detection techniques, of which radar detection is a candidate. The software simulation of radar scattering from cosmic rays follows. The TARA detector, including transmitter and receiver systems, are discussed in detail. Our search algorithm and methodology for calculating RCS is presented for the purpose of being repeatable. Search results are explained in context of the usefulness and future of cosmic ray radar detection.

  5. Low Complexity Receiver Design for MIMO-Radar

    KAUST Repository

    2012-09-08

    In this work, an algorithm for the multiple-input multiple-output (MIMO) radar is proposed. It has low computational complexity compared to the available schemes, and relatively low side-lobe-levels in the receive beampattern compared to the phased-array and MIMO-radar. In the proposed algorithm, the received signal vector of MIMO-radar is divided into sub-vectors, and each sub-vector is multiplied with the corresponding weight vector. The number of sub-vectors and weight vectors are optimally found to maximise the received signal power from the target of interest direction. The proposed scheme can be effectively applied in passive radars to minimise the side-lobe levels and place deep nulls for interferers in the receive beampattern. Simulation results show that the proposed scheme has relatively lower side lobe levels and better detection capabilities compared to MIMO-radar and phased-array.

    There has been research interest in using radar for contactless measurements of the human heartbeat for several years. While many systems have been demonstrated, not much attention have been given to the actual physical causes of why this work. The consensus seems to be that the radar senses small body movements correlated with heartbeats, but whether only the movements of the body surface or reflections from internal organs are also monitored have not been answered definitely. There has recently been proposed another theory that blood perfusion in the skin could be the main reason radars are able to detect heartbeats. In this paper, an experimental approach is given to determine the physical causes. The measurement results show that it is the body surface reflections that dominate radar measurements of human heartbeats.

    Measurements of the wind and turbulent regions from the surface to 16 km by the FPS-11 radar/jimsphere system are reported with particular attention given to the use of these turbulence and wind assessments to validate the NASA 50-MHz radar wind profiler. Wind profile statistics were compared at 150-m wavelengths, a wavelength validated from 20 jimspheres, simultaneously tracked by FPS-16 and FPQ-14 radar, and the resulting analysis of auto spectra, cross-spectra, and coherence squared spectra of the wind profiles. Results demonstrate that the NASA prototype wind profiler is an excellent monitoring device illustrating the measurements of the winds within 1/2 hour of launch zero.

  11. To See the Unseen: A History of Planetary Radar Astronomy

    Science.gov (United States)

    Butrica, Andrew J.

    1996-01-01

    This book relates the history of planetary radar astronomy from its origins in radar to the present day and secondarily to bring to light that history as a case of 'Big Equipment but not Big Science'. Chapter One sketches the emergence of radar astronomy as an ongoing scientific activity at Jodrell Bank, where radar research revealed that meteors were part of the solar system. The chief Big Science driving early radar astronomy experiments was ionospheric research. Chapter Two links the Cold War and the Space Race to the first radar experiments attempted on planetary targets, while recounting the initial achievements of planetary radar, namely, the refinement of the astronomical unit and the rotational rate and direction of Venus. Chapter Three discusses early attempts to organize radar astronomy and the efforts at MIT's Lincoln Laboratory, in conjunction with Harvard radio astronomers, to acquire antenna time unfettered by military priorities. Here, the chief Big Science influencing the development of planetary radar astronomy was radio astronomy. Chapter Four spotlights the evolution of planetary radar astronomy at the Jet Propulsion Laboratory, a NASA facility, at Cornell University's Arecibo Observatory, and at Jodrell Bank. A congeries of funding from the military, the National Science Foundation, and finally NASA marked that evolution, which culminated in planetary radar astronomy finding a single Big Science patron, NASA. Chapter Five analyzes planetary radar astronomy as a science using the theoretical framework provided by philosopher of science Thomas Kuhn. Chapter Six explores the shift in planetary radar astronomy beginning in the 1970s that resulted from its financial and institutional relationship with NASA Big Science. Chapter Seven addresses the Magellan mission and its relation to the evolution of planetary radar astronomy from a ground-based to a space-based activity. Chapters Eight and Nine discuss the research carried out at ground

    Phased Array Weather Radar (PAWR) was firstly developed in 2012 by Osaka University and Toshiba under a grant of NICT using the Digital Beamforming Technique, and showed a impressive thunderstorm behavior with 30 second resolution. After that development, second PAWR was installed in Kobe city about 60 km away from the first PAWR site, and Tokyo Metropolitan University, Osaka Univeristy, Toshiba and the Osaka Local Government started a new project to develop the Osaka Urban Demonstration Network. The main sensor of the Osaka Network is a 2-node Phased Array Radar Network and lightning location system. Data products that are created both in local high performance computer and Toshiba Computer Cloud, include single and multi-radar data, vector wind, quantitative precipitation estimation, VIL, nowcasting, lightning location and analysis. Each radar node is calibarated by the baloon measurement and through the comparison with the GPM (Global Precipitation Measurement)/ DPR (Dual Frequency Space borne Radar) within 1 dB. The attenuated radar reflectivities obtained by the Phased Array Radar Network at X band are corrected based on the bayesian scheme proposed in Shimamura et al. [2016]. The obtained high resolution (every 30 seconds/ 100 elevation angles) 3D reflectivity and rain rate fields are used to nowcast the surface rain rate up to 30 minutes ahead. These new products are transferred to Osaka Local Government in operational mode and evaluated by several section in Osaka Prefecture. Furthermore, a new Phased Array Radar with polarimetric function has been developed in 2017, and will be operated in the fiscal year of 2017. In this presentation, Phased Array Radar, network architecuture, processing algorithm, evalution of the social experiment and first Multi-Prameter Phased Array Radar experiment are presented.

  20. Radar investigations at the Saltsjoetunnel - predictions and validation

    Olsson, Olle; Palmqvist, Kai

    1989-01-01

    Borehole radar investigations have been performed in two boreholes drilled along the extent of the Saltsjoe tunnel in Stockholm, Sweden. The objective of the project was to test investigate the capabilities of the borehole radar technique to predict geological structures prior to tunnel excavation. Singlehole and crosshole radar measurements were made in the two boreholes which outlined and equilateral triangle. The crosshole data was used to produce tomograms showing the distribution of radar attenuation and slowness (inverse of velocity) in the plane between the boreholes. The radar model of the site contained one major feature which was identified as a fracture zone. The intersection of the fracture zone with the tunnel was extrapolated from the radar data and found to be in agreement with observations in the tunnel. At the intersection of the fracture zone with the tunnel grouting had to be applied. It has also been found that the radar identifies a number of smaller features which are of practically no significance with respect to tunnel construction. There is general agreement between the radar model of the site and the geologic-tectonic model of the site. This project has demonstrated the capability of the boreholes radar technique to predict the existence, location, and orientation of geologic features (e.g. fracture zones) which can be of significance to the cost and safety when excavating a tunnel. However, further development is needed to be able to use the technique cost effectively for continuous prediction ahead of the tunnel front. (authors) (17 figs., 1 tab.)

    2010-01-01

    In searching for different patterns of practice, lifestyle, and environment supportive of optimal health, we look to our elders around the world, who in the wisdom that has sustained them, we learn from with careful attention. Thirty-seven elders who live by their traditions participated in the present study. They assisted in the refinement of the methodology and collections and preparation of these data. These participants are well-respected, representative elders and traditional healers of their regions. These data, from study sites of the Eastern Afromontane and Albertine Rift region of Ethiopia, Africa; the Maya Mountains region of Belize, Central America; the Western Ghats region of India; and the Appalachian Mountains region of the United States, were grouped into three major categories: (1) philosophy, attitudes, and outlook, (2) lifestyle practices, and (3) dietary and nutritional practices. These elders demonstrate a relatively comprehensive but simple set of practices that can enhance our vitality and promote longevity sustainably. In essence, these practices, or practice wisdom, of our longest living elders, promote propagation of healthful lifestyles by following traditional ways and taking care of body, mind, spirit and our environment. Further field research among a larger cohort is required to fully generalize the findings of this study, but much of it is consistent with what we already know should be done. These data begin illustration of practice wisdom for implementation and serve to engage our universities, our hospitals, our industries, and our students, who we must position toward social change.

    Radar, Sonar, and Holography: An Introduction provides an introduction to the technology of radar and sonar. Because the new science of holography is affecting both these fields quite strongly, the book includes an explanation of the fundamental principles underlying this new art (including the subjects of wave coherence, interference, and diffraction) and of the hologram process itself. Finally, numerous examples are discussed which show how holography is providing new horizons to radar and sonar systems. The book thus also provides a simple approach to the new technology of holography. The

  6. Detecting and mitigating wind turbine clutter for airspace radar systems.

    2013-01-01

    It is well recognized that a wind turbine has a large radar cross-section (RCS) and, due to the movement of the blades, the wind turbine will generate a Doppler frequency shift. This scattering behavior may cause severe interferences on existing radar systems including static ground-based radars and spaceborne or airborne radars. To resolve this problem, efficient techniques or algorithms should be developed to mitigate the effects of wind farms on radars. Herein, one transponder-based mitigation technique is presented. The transponder is not a new concept, which has been proposed for calibrating high-resolution imaging radars. It modulates the radar signal in a manner that the retransmitted signals can be separated from the scene echoes. As wind farms often occupy only a small area, mitigation processing in the whole radar operation will be redundant and cost inefficient. Hence, this paper uses a transponder to determine whether the radar is impacted by the wind farms. If so, the effects of wind farms are then mitigated with subsequent Kalman filtering or plot target extraction algorithms. Taking airborne synthetic aperture radar (SAR) and pulse Doppler radar as the examples, this paper provides the corresponding system configuration and processing algorithms. The effectiveness of the mitigation technique is validated by numerical simulation results.

    The various embodiments presented herein relate to utilizing an operational single-channel radar to collect and process synthetic aperture radar (SAR) and ground moving target indicator (GMTI) imagery from a same set of radar returns. In an embodiment, data is collected by randomly staggering a slow-time pulse repetition interval (PRI) over a SAR aperture such that a number of transmitted pulses in the SAR aperture is preserved with respect to standard SAR, but many of the pulses are spaced very closely enabling movers (e.g., targets) to be resolved, wherein a relative velocity of the movers places them outside of the SAR ground patch. The various embodiments of image reconstruction can be based on compressed sensing inversion from undersampled data, which can be solved efficiently using such techniques as Bregman iteration. The various embodiments enable high-quality SAR reconstruction, and high-quality GMTI reconstruction from the same set of radar returns.

  11. A Dual-Wavelength Radar Technique to Detect Hydrometeor Phases

    Science.gov (United States)

    Liao, Liang; Meneghini, Robert

    2016-01-01

    This study is aimed at investigating the feasibility of a Ku- and Ka-band space/air-borne dual wavelength radar algorithm to discriminate various phase states of precipitating hydrometeors. A phase-state classification algorithm has been developed from the radar measurements of snow, mixed-phase and rain obtained from stratiform storms. The algorithm, presented in the form of the look-up table that links the Ku-band radar reflectivities and dual-frequency ratio (DFR) to the phase states of hydrometeors, is checked by applying it to the measurements of the Jet Propulsion Laboratory, California Institute of Technology, Airborne Precipitation Radar Second Generation (APR-2). In creating the statistically-based phase look-up table, the attenuation corrected (or true) radar reflectivity factors are employed, leading to better accuracy in determining the hydrometeor phase. In practice, however, the true radar reflectivities are not always available before the phase states of the hydrometeors are determined. Therefore, it is desirable to make use of the measured radar reflectivities in classifying the phase states. To do this, a phase-identification procedure is proposed that uses only measured radar reflectivities. The procedure is then tested using APR-2 airborne radar data. Analysis of the classification results in stratiform rain indicates that the regions of snow, mixed-phase and rain derived from the phase-identification algorithm coincide reasonably well with those determined from the measured radar reflectivities and linear depolarization ratio (LDR).

    If the borehole radar is utilized for detection of buried pipes, the underground radar measurement becomes possible even in the situation where the mesurement on the earth surface is difficult, for example, such a place as under the road where there is much traffic. However, since buried pipes are horizontally installed and the existing borehole radar can send/receive only vertical polarization, the measurement conducted comes to be poor in efficiency from a viewpoint of the polarization utilization. Therefore, by introducing the polarimetric borehole radar to the detection of buried pipes, a basic experiment was conducted for the effective detection of horizontal buried pipes. Proposing the use of a slot antenna which can send/receive horizontal polarization in borehole in addition to a dipole antenna which sends/receives vertical polarization, developed was a step frequency type continuous wave radar of a network analyzer basis. As a result of the experiment, it was confirmed that reflection from buried pipes is largely dependent on polarization. Especially, it was found that in the slot dipole cross polarization mesurement, reflection from buried pipes can be emphasized. 4 refs., 5 figs.

    The work described in this report represents the first phase of a planned three-phase project designed to develop a radar system for monitoring waste canisters stored in a thick layer of bedded salt at the Waste Isolation Pilot Plant near Carlsbad, New Mexico. The canisters will be contained in holes drilled into the floor of the underground waste storage facility. It is hoped that these measurements can be made to accuracies of +-5 cm and +-2/sup 0/, respectively. The initial phase of this project was primarily a feasibility study. Its principal objective was to evaluate the potential effectiveness of the radar method in the planned canister monitoring application. Its scope included an investigation of the characteristics of radar signals backscattered from waste canisters, a test of preliminary data analysis methods, an assessment of the effects of salt and bentonite (a proposed backfill material) on the propagation of the radar signals, and a review of current ground-penetrating radar technology. A laboratory experiment was performed in which radar signals were backscattered from simulated waste canisters. The radar data were recorded by a digital data acquisition system and were subsequently analyzed by three different computer-based methods to extract estimates of canister location and tilt. Each of these methods yielded results that were accurate within a few centimeters in canister location and within 1/sup 0/ in canister tilt. Measurements were also made to determine the signal propagation velocities in salt and bentonite (actually a bentonite/sand mixture) and to estimate the signal attenuation rate in the bentonite. Finally, a product survey and a literature search were made to identify available ground-penetrating radar systems and alternative antenna designs that may be particularly suitable for this unique application. 10 refs., 21 figs., 4 tabs.

In our history from a black perspective, Christianity arrived through violent conquest from the west. Evidentially, this faith coincided with wars of dispossession and the ultimate defeat of black Africans. It is difficult to separate the violent defeat of black Africans from the arrival of Christian faith. This well-known statement within the circles of black Theology of liberation: When the white man arrived in our land he said, �let us pray and after prayer, when we opened our eyes, our land was taken and only the Bible was left in our hands,� captures the black sentiment of this history. Ironically, it was this Bible that black Africans used to wage their struggle for liberation up to the demise of apartheid in 1994.Nonetheless, political liberation is not enough as the struggle for economic liberation

    Operating weather radars in high-mountain regions faces the following well-known dilemma: (1) installing radar on top of mountains allows for the detection of severe summer convective events over 360° but may give poor QPE performance during a very significant part of the year when the 0°C isotherm is located below or close to the radar altitude; (2) installing radar at lower altitudes may lead to better QPE over sensitive areas such as cities located in valleys, but at the cost of reduced visibility and detection capability in other geographical sectors. We have the opportunity to study this question in detail in the region of Grenoble (an Alpine city of 500 000 inhabitants with an average altitude of 210 m asl) with a pair of X-band polarimetric weather radars operated respectively by Meteo-France on top of Mount Moucherotte (1920 m asl) and by IGE on the Grenoble Campus (213 m asl). The XPORT radar (IGE) performs a combination of PPIs at elevations of 3.5, 7.5, 15 and 25° complemented by two RHIs in the vertical plane passing by the two radar sites, in order to document the 4D precipitation variability within the Grenoble intermountain valley. In the proposed communication, preliminary results of this experiment (started in September 2016) will be presented with highlights on (1) the calibration of the two radar systems, (2) the characterization of the melting layer during significant precipitation events (>5mm/day) occurring in autumn, winter and spring; (3) the simulation of the relative effects of attenuation and non-uniform beam filling at X-band and (4) the possibility to use the mountain returns for quantifying the attenuation by the rain and the melting layer.

    Across Europe more than 110 weather radars are in operation. More than 60 of them are Doppler radars and this number is increasing steadily. Doppler systems are becoming an operational standard. Most systems operate in C-band, with the exception of the Spanish radar network which is composed of S-band Doppler radars. Radar product composites are available for Scandinavia and Central Europe. National networks exist for the UK, France and Spain. Europe further is fortunate to have 8 polarimetric Doppler radars used mainly for research. In Italy some of those systems are used also for operational nowcasting applications for dedicated customers. The Chilbolton multiparameter Doppler radar operates at S-band. (orig.)

However, the work so far has been focused on the rainfall data from traditional raingauges. Weather radar is a modern technology which could provide high resolution rainfall in time and space. In this study, a comparison in rainfall runoff modelling between the raingauge and weather radar has been carried out. The data were collected from Brue catchment in Southwest of England, with 49 raingauges covering 136 km2 and two C-band weather radars. This raingauge network is extremely dense (for research purposes and does not represent the usual raingauge density in operational flood forecasting systems. The ANN models were set up with both lumped and spatial rainfall input. The results showed that raingauge data outperformed radar data in all the events tested, regardless of the lumped and spatial input.

    The main objectives of the study were: to determine the effects of siting wind turbines adjacent to primary air traffic control radar; to gather the information required for the generation of guidelines by civil, military and wind farm developer stakeholders; to determine the extent to which the design of wind turbines influences their effects on radar systems and to determine the extent to which design of the radar processing influences the effects of wind turbines on radar systems. A computer model was developed to predict the Radar Cross Section (RCS) of wind turbines and understand the interaction of radar energy and turbines. The model was designed to predict and simulate the impact of wind farms on the primary radar display. Validation of the model was carried out in a full-scale trial and modelling process, with data collected from a number of sources. The model was validated against a single turbine scenario and showed an accurate prediction capability. Further validation of the model could be gained through a multiple turbine trial. The knowledge gained from the development and validation of the predictive computer model has been used to conduct a sensitivity analysis (of the sub-elements of the radar and wind farm interaction) and to compile a list of the key factors influencing the radar signature of wind turbines. The result is a more detailed quantification of the complex interactions between wind turbines and radar systems than was previously available. The key findings of how the design, size and construction materials of wind turbines affect RCS are summarised.

    Subcutaneous emphysema is a rare complication in oral surgery. In most cases, it resolves spontaneously. However, air might disperse into deeper facial spaces causing life-threatening complications such as compression of the tracheobronchial tree or the development of pneumomediastinum. Moreover, microorganisms might spread from the oral cavity into deeper spaces. Hence, rapid diagnosis of subcutaneous emphysema is important. Characteristic signs are both a shiftable swelling and crepitation. In this case report, a 30-year-old man, suffering from the Gilles de la Tourette Syndrome, with a distinct subcutaneous emphysema after bilateral surgical wisdom tooth extraction is presented. Induced by a specific motor tic, air accumulated from the periorbital through to the parapharyngeal region. Applying a 10-cm-long Redon drainage tube as air valve, 10 days after wisdom teeth extraction, the patient was asymptomatic with complete resolution of the emphysema.

    Full Text Available Passive radar is a topic anti stealth technology with simple structure, and low cost. Radiation source model, signal transmission model, and target detection are the key points of passive radar technology research. The paper analyzes the characteristics of EBPSK signal modulation and target detection method aspect of spaceborne radiant source. By comparison with other satellite navigation and positioning system, the characteristics of EBPSK satellite passive radar system are analyzed. It is proved that the maximum detection range of EBPSK satellite signal can satisfy the needs of the proposed model. In the passive radar model, sparse representation is used to achieve high resolution DOA detection. The comparison with the real target track by simulation demonstrates that effective detection of airborne target using EBPSK satellite passive radar system based on sparse representation is efficient.

    Researchers developed a radar-echo model for Mars based on 12.6 cm continuous wave radio transmissions backscattered from the planet. The model broadly matches the variations in depolarized and polarized total radar cross sections with longitude observed by Goldstone in 1986 along 7 degrees S. and yields echo spectra that are generally similiar to the observed spectra. Radar map units in the model include an extensive cratered uplands unit with weak depolarized echo cross sections, average thermal inertias, moderate normal refelectivities, and moderate rms slopes; the volcanic units of Tharsis, Elysium, and Amazonis regions with strong depolarized echo cross sections, low thermal inertia, low normal reflectivities, and large rms slopes; and the northern planes units with moderate to strong depolarized echo cross sections, moderate to very high thermal inertias, moderate to large normal reflectivities, and moderate rms slopes. The relevance of the model to the interpretation of radar echoes from Mars is discussed

  20. The place of practical wisdom in science education: what can be learned from Aristotelian ethics and a virtue-based theory of knowledge

    Salloum, Sara

    2017-06-01

    This conceptual paper aims to characterize science teachers' practical knowledge utilizing a virtue-based theory of knowledge and the Aristotelian notion of phronesis/practical wisdom. The article argues that a greater understanding of the concept of phronesis and its relevance to science education would enrich our understandings of teacher knowledge, its development, and consequently models of teacher education. Views of teacher knowledge presented in this paper are informed by philosophical literature that questions normative views of knowledge and argues for a virtue-based epistemology rather than a belief-based one. The paper first outlines general features of phronesis/practical wisdom. Later, a virtue-based view of knowledge is described. A virtue-based view binds knowledge with moral concepts and suggests that knowledge development is motivated by intellectual virtues such as intellectual sobriety, perseverance, fairness, and humility. A virtue-based theory of knowledge gives prominence to the virtue of phronesis/practical wisdom, whose primary function is to mediate among virtues and theoretical knowledge into a line of action that serves human goods. The role of phronesis and its relevance to teaching science are explained accordingly. I also discuss differences among various characterizations of practical knowledge in science education and a virtue-based characterization. Finally, implications and further questions for teacher education are presented.

    1994-01-01

    This spaceborne radar image shows a segment of the Columbia River as it passes through the area of Wenatchee, Washington, about 220 kilometers (136 miles) east of Seattle. The Wenatchee Mountains, part of the Cascade Range, are shown in green at the lower left of the image. The Cascades create a 'rain shadow' for the region, limiting rainfall east of the range to less than 26 centimeters (10 inches) per year. The radar's ability to see different types of vegetation is highlighted in the contrast between the pine forests, that appear in green and the dry valley plain that shows up as dark purple. The cities of Wenatchee and East Wenatchee are the grid-like areas straddling the Columbia River in the left center of the image. With a population of about 60,000, the region produces about half of Washington state's lucrative apple crop. Several orchard areas appear as green rectangular patches to the right of the river in the lower right center. Radar images such as these can be used to monitor land use patterns in areas such as Wenatchee, that have diverse and rapidly changing urban, agricultural and wild land pressures. This image was acquired by Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the space shuttle Endeavour on October 10, 1994. The image is 38 kilometers by 45 kilometers (24 miles by 30 miles) and is centered at 47.3 degrees North latitude, 120.1 degrees West longitude. North is toward the upper left. The colors are assigned to different radar frequencies and polarizations of the radar as follows: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted, vertically received; and blue is C-band, horizontally transmitted, vertically received. SIR-C/X-SAR, a joint mission of the German, Italian, and United States space agencies, is part of NASA's Mission to Planet Earth.

    Full Text Available Le premier geste de l’espace architectural est d’accueillir nos corps humains. En leur offrant un espacement à habiter, il leur permet de s’abriter, de se mouvoir et de se rencontrer. L’homme et l’architecture s’affectent l’un l’autre. Nombreux sont les architectes qui interrogent cette coexistence car, renouveler la pensée de l’espace nécessite de reconsidérer le corps humain. L’étude des relations entre le corps et l’espace chez trois architectes français sera l’occasion d’évoquer les écarts et les convergences entre l’homme et l’architecture. L’œuvre de Le Corbusier, protagoniste du mouvement moderne, maintient ainsi une distance entre un corps machinisé et un espace idéal. Marquée par un mode de pensée dualiste, l’architecture de Le Corbusier annonce toutefois son propre dépassement, dépassement que Claude Parent et Henri Gaudin opèreront par la suite à leur manière, le premier en introduisant l’oblique et la déstabilisation du corps, le second en transgressant la limite de l’espace et du corps pour envisager leur porosité réciproque. Finalement, c’est la manière dont l’homme appréhende l’espace avec son corps qui est questionnée par ces trois architectes, de la prégnance du visuel à son évincement.

  4. Beware of ligand efficiency (LE): understanding LE data in modeling structure-activity and structure-economy relationships.

    On the one hand, ligand efficiency (LE) and the binding efficiency index (BEI), which are binding properties (B) averaged versus the heavy atom count (HAC: LE) or molecular weight (MW: BEI), have recently been declared a novel universal tool for drug design. On the other hand, questions have been raised about the mathematical validity of the LE approach. In fact, neither the critics nor the advocates are precise enough to provide a generally understandable and accepted chemistry of the LE metrics. In particular, this refers to the puzzle of the LE trends for small and large molecules. In this paper, we explain the chemistry and mathematics of the LE type of data. Because LE is a weight metrics related to binding per gram, its hyperbolic decrease with an increasing number of heavy atoms can be easily understood by its 1/MW dependency. Accordingly, we analyzed how this influences the LE trends for ligand-target binding, economic big data or molecular descriptor data. In particular, we compared the trends for the thermodynamic ∆G data of a series of ligands that interact with 14 different target classes, which were extracted from the BindingDB database with the market prices of a commercial compound library of ca. 2.5 mln synthetic building blocks. An interpretation of LE and BEI that clearly explains the observed trends for these parameters are presented here for the first time. Accordingly, we show that the main misunderstanding of the chemical meaning of the BEI and LE parameters is their interpretation as molecular descriptors that are connected with a single molecule, while binding is a statistical effect in which a population of ligands limits the formation of ligand-receptor complexes. Therefore, LE (BEI) should not be interpreted as a molecular (physicochemical) descriptor that is connected with a single molecule but as a property (binding per gram). Accordingly, the puzzle of the surprising behavior of LE is explained by the 1/MW dependency. This effect

    Radar altimetry is very much a technique expanding its applications. If quite a lot of efforts have been made for oceanography users (including easy-to-use data), the use of those data for cryosphere application, especially with the new ESA CryoSat-2 mission data is still somehow tedious, especially for new Altimetry data products users. ESA and CNES thus had the Basic Radar Altimetry Toolbox developed a few years ago, and are improving and upgrading it to fit new missions and the growing number of altimetry uses. The Basic Radar Altimetry Toolbox is an "all-altimeter" collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data. The software is able: - to read most distributed radar altimetry data, from ERS-1 & 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, Jason- 2, CryoSat and the future Saral missions, - to perform some processing, data editing and statistic, - and to visualize the results. It can be used at several levels/several ways: - as a data reading tool, with APIs for C, Fortran, Matlab and IDL - as processing/extraction routines, through the on-line command mode - as an educational and a quick-look tool, with the graphical user interface As part of the Toolbox, a Radar Altimetry Tutorial gives general information about altimetry, the technique involved and its applications, as well as an overview of past, present and future missions, including information on how to access data and additional software and documentation. It also presents a series of data use cases, covering all uses of altimetry over ocean, cryosphere and land, showing the basic methods for some of the most frequent manners of using altimetry data. It is an opportunity to teach remote sensing with practical training. It has been available from April 2007, and had been demonstrated during training courses and scientific meetings. About 1200 people downloaded it (Summer 2010), with many "newcomers" to altimetry among them, including teachers

    A dense weather radar network is an emerging concept advanced by the Center for Collaborative Adaptive Sensing of the Atmosphere (CASA). Using multiple radars observing over a common will create different data outcomes depending on the characteristics of the radar units employed and the network topology. To define this a general framework is developed to describe the radar network space, and formulations are obtained that can be used for weather radar network characterization. Current weather radar surveillance networks are based upon conventional sensing paradigm of widely-separated, standalone sensing systems using long range radars that operate at wavelengths in 5-10 cm range. Such configuration has limited capability to observe close to the surface of the earth because of the earth's curvature but also has poorer resolution at far ranges. The dense network radar system, observes and measures weather phenomenon such as rainfall and severe weather close to the ground at higher spatial and temporal resolution compared to the current paradigm. In addition the dense network paradigm also is easily adaptable to complex terrain. Flooding is one of the most common natural hazards in the world. Especially, excessive development decreases the response time of urban watersheds and complex terrain to rainfall and increases the chance of localized flooding events over a small spatial domain. Successful monitoring of urban floods requires high spatiotemporal resolution, accurate precipitation estimation because of the rapid flood response as well as the complex hydrologic and hydraulic characteristics in an urban environment. This paper reviews various aspects in radar rainfall mapping in urban coverage using dense X-band dual-polarization radar networks. By reducing the maximum range and operating at X-band, one can ensure good azimuthal resolution with a small-size antenna and keep the radar beam closer to the ground. The networked topology helps to achieve satisfactory

    2006-06-01

    Full Text Available Le « peer to peer » est la dynamique intersubjective caractéristique des réseaux distribués. Le but de cet essai est de montrer qu’il s’agit d’une véritable nouvelle forme d’organisation sociale, apte à produire et échanger des biens, à créer de la valeur. Celle-ci est la conséquence d’un nouvel imaginaire social, et possède le potentiel de devenir le pilier d’un nouveau mode d’économie politique, voire d’un nouveau type de civilisation. Pour cela, nous allons d’abord définir le P2P, décrire en bref ces manifestations, et le différencier d’autres modalités d’échange intersubjectif tel que le marché, la hiérarchie, l’économie du don. Comme principale modalité P2P nous distinguons: Les processus de production P2P, comme troisième mode de production, qui n’est ni géré par un mode hiérarchique ou par l’état, ni répondant à des impératifs de profit ou qui sont modulés par le biais des prix. Les processus de gouvernance P2P, qui gouverne ces processus de production. Les formes de propriété P2P, qui sont destine a empecher l’appropriation prive de cette production pour le commun. Afin d’examiner les characteristiques de cette nouvelle dynamique sociale, nous utilisons la typologie intersubjective de l’anthropologue Alan Page Fisque, qui distingue: 1. l’échange égalitaire (Equality Matching, c..a.d l’economie du don. 2. La relation d’autorité (Authority Ranking tel qu’elle s’exprime dans le mode hierarchique. 3. le marché (Market Pricing. 4. la participation commune (Communal Shareholding. En conclusion, nous examinons les possibilites d’expansion de ce nouveau mode sociale et son insertion dans l’economie capitaliste, en nous nous posons la question: le P2P peut-il etre concu comme alternative sociale et economique aux modeles existants. Abstract: “Peer to peer” is hypothesized as a new social formation with intersubjective dynamics characteristic of distributed

  12. Herbal Wisdom: memory and migration

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Within contemporary Western herbal medicine, traditional knowledge and modern science are combined to provide a unique meeting of patient, practitioner and plant. In the Australian context, herbalists have based their practice on knowledge which originates from the traditions of Europe, and has more recently been influenced by traditional medicine from Asia. The combination of these diverse ways of knowing—traditional and modern, Eastern and Western—means herbal practitioners are influenced by ancient philosophy alongside phytochemistry and biomedical sciences. The challenge for herbal medicine today is that faced by all living (as opposed to ossified traditions: how is a practice forged which retains what is valuable from the past while establishing relevance to the 21st century? We illustrate these issues in the context of the conference theme of ‘food for thought’ and consider medicinal plants which are used for the improvement of cognition. We focus on the therapeutic use of common herbs from the Eastern and Western traditions and present the scientific research which shows their ability to facilitate cognitive function and the laying down of memory. We also tell their traditional stories which indicate that these actions have been recognised and utilised for centuries. We go on to demonstrate, via case studies, the clinical application of this knowledge and in particular the importance of ancient practice of synergistic prescribing which occurs when a number of herbs are prescribed together in a formula. Scientific understanding of the basis of this practice is being developed which further complements and validates traditional herbal wisdom.

    Widdershoven, Guy A M; Ruissen, Andrea; van Balkom, Anton J L M; Meynen, Gerben

    2017-06-01

    The concept of competence is central to healthcare because informed consent can only be obtained from a competent patient. The standard approach to competence focuses on cognitive abilities. Several authors have challenged this approach by emphasising the role of emotions and values. Combining cognition, emotion and values, we suggest an approach which is based on the notion of practical wisdom. This focuses on knowledge and on determining what is important in a specific situation and finding a balance between various values, which are enacted in an individual's personal life. Our approach is illustrated by two cases of patients with obsessive-compulsive disorder. Published by the BMJ Publishing Group Limited.

    Full Text Available Le scientifique promet la vérité sans être en mesure d'accomplir sa promesse tandis que l'écrivain promet de mentir mais par son mensonge, il fait plus que mentir. Il ne dit certainement pas la vérité, car la vérité n'est pas sa préoccupation première. Voilà comment nous pouvons résumer les deux attitudes, condamnées à un antagonisme stérile par l'attitude positiviste moderne. Compte tenu donc de l'intention fondatrice de la science, de sa promesse donc originaire et fondatrice, la science doit dire la vérité et rien que la vérité. Ce qui, de l'aveu même de cette même science, est impossible. [...] La littérature se permet de reconstruire des mondes par-delà le vrai et le faux. [...] Un récit littéraire ne demande pas la consécration de la vérité, ne demande pas à être suivi parce que vrai, n'impose rien et n'attend rien. Sa vraie destinée est l'errance et sa vraie conscience est celle de sa dissémination. Celui qui renonce à la prétention de vérité renonce en même temps à la volonté de dominer. Dominer signifie créer un espace de vérité dans lequel celui qui énonce la vérité est le maître légitime de ceux qui sont dans le champ de la conception du monde dont cette vérité est la pierre angulaire.

Par quel mystère le langage mathématique, pure création de l'esprit humain, se révèle-t-il aussi performant pour nous décrire les phénomènes physiques, de l'infiniment petit à l'infiniment grand ?

  8. Power centroid radar and its rise from the universal cybernetics duality

    Science.gov (United States)

    Feria, Erlan H.

    2014-05-01

    Power centroid radar (PC-Radar) is a fast and powerful adaptive radar scheme that naturally surfaced from the recent discovery of the time-dual for information theory which has been named "latency theory." Latency theory itself was born from the universal cybernetics duality (UC-Duality), first identified in the late 1970s, that has also delivered a time dual for thermodynamics that has been named "lingerdynamics" and anchors an emerging lifespan theory for biological systems. In this paper the rise of PC-Radar from the UC-Duality is described. The development of PC-Radar, US patented, started with Defense Advanced Research Projects Agency (DARPA) funded research on knowledge-aided (KA) adaptive radar of the last decade. The outstanding signal to interference plus noise ratio (SINR) performance of PC-Radar under severely taxing environmental disturbances will be established. More specifically, it will be seen that the SINR performance of PC-Radar, either KA or knowledgeunaided (KU), approximates that of an optimum KA radar scheme. The explanation for this remarkable result is that PC-Radar inherently arises from the UC-Duality, which advances a "first principles" duality guidance theory for the derivation of synergistic storage-space/computational-time compression solutions. Real-world synthetic aperture radar (SAR) images will be used as prior-knowledge to illustrate these results.

    Okamoto, Ken'ichi; Ihara, Toshio; Kumagai, Hiroshi

    The active array radar was selected as a reliable candidate for the TRMM (Tropical Rainfall Measuring Mission) precipitation radar after the trade off studies performed by Communications Research Laboratory (CRL) in the US-Japan joint feasibility study of TRMM in 1987-1988. Main system parameters and block diagram for TRMM precipitation radar are shown as the result of feasibility study. CRL developed key devices for the active array precipitation radar such as 8-element slotted waveguide array antenna, the 5 bit PIN diode phase shifters, solid state power amplifiers and low noise amplifiers in 1988-1990. Integration of these key devices was made to compose 8-element Bread Board Model of TRMM precipitation radar.

  11. Rejecting conventional wisdom: how academic medical centers can regain their leadership positions.

    Science.gov (United States)

    Krauss, K; Smith, J

    1997-07-01

    Academic medical centers (i.e., medical schools and their principal hospitals) are following very similar strategies in attempts to secure their futures. It is likely that these undifferentiated strategies will fail, since most of them have been copied from the lower-cost, geographically better-positioned hospitals and health systems. Despite a wealth of innovative, entrepreneurial talent and the potential to reshape the world that AMCs live in, most AMCs are in reactive modes. Future directions and strategies are almost always shaped, forced, and justified by external pressures. The major problem with the strategic plans of most AMCs is that they are based on conventional industry wisdom. Strategic plans tend not to be analytically driven. The insight and understanding of those factors that drive the demand for AMCs' services and determine the performances of AMCs are lacking. The authors note some questions that are critical to the formulation of strategies for AMCs. For example, how can the research mission be changed from a cost-based to a value-based endeavor? Most AMCs cannot answer these questions, and if they do address them in the planning process, they do so superficially. Several examples of the factors that need to be understood are also given, such as patients' purposes and needs in seeking specialty care. Alternative strategies are listed, such as maintaining and exploiting the economic irrationality of the market rather than acting as if it were economically rational or forcing it to become so. Last, the authors outline the scope of the changes that are required and urge AMCs to reject conventional wisdom, determine their own unique situations, and work from there.

  13. Single Frequency Network Based Distributed Passive Radar Technology

    Wan Xian-rong

    2015-01-01

    Full Text Available The research and application of passive radar are heading from single transmitter-receiver pair to multiple transmitter-receiver pairs. As an important class of the illuminators of opportunity, most of modern digital broadcasting and television systems work on Single Frequency Network (SFN, which intrinsically determines that the passive radar based on such illuminators must be distributed and networked. In consideration of the remarkable working and processing mode of passive radar under SFN configuration, this paper proposes the concept of SFN-based Distributed Passive Radar (SDPR. The main characteristics and key problems of SDPR are first described. Then several potential solutions are discussed for part of the key technologies. The feasibility of SDPR is demonstrated by preliminary experimental results. Finally, the concept of four network convergence that includes the broadcast based passive radar network is conceived, and its application prospects are discussed.

  14. Experimentelles FMCW-Radar zur hochfrequenten Charakterisierung von Windenergieanlagen

    Science.gov (United States)

    Schubert, Karsten; Werner, Jens; Schwartau, Fabian

    2017-09-01

    During the increasing dissemination of renewable energy sources the potential and actual interference effects of wind turbine plants became obvious. Turbines reflect the signals of weather radar and other radar systems. In addition to the static radar echoes, in particular the Doppler echoes are to be mentioned as an undesirable impairment Keränen (2014). As a result, building permit is refused for numerous new wind turbines, as the potential interference can not be reliably predicted. As a contribution to the improvement of this predictability, measurements are planned which aim at the high-frequency characterisation of wind energy installations. In this paper, a cost-effective FMCW radar is presented, which is operated in the same frequency band (C-band) as the weather radars of the German weather service. Here, the focus is on the description of the hardware design including the considerations used for its dimensioning.
