  3. [Who shot Erik XIV?].

    Though Sweden was still at war with Denmark a revolution took place in 1568 and King Erik XIV was dethroned by his brothers Johan (John) and Karl (Charles). The situation was chaotic and the brothers didn't know how to dispose of the King. To execute or to expatriate him was far too dangerous, consequently remained to keep him imprisoned. This solution to the problem was not without hazards since Erik had many friends who repeatedly tried to free him. The former king, however, also had many enemies, one of whom was Olof Gustafsson Stenbock a man who was responsible for the guarding of Erik. Olof Gustafsson had himself been sentenced to death by King Erik but been reprieved. His brother Abraham Gustafsson Stenbock was on the other hand executed on the order of the King. On the 19th September 1569 Olof Gustafsson visited the imprisoned king, who rushed to his feet, attacking Olof Gustafsson. Olof retreated, took out his gun and shot the King in his left forearm. The King survived 8 years with a badly wounded arm which probably was of no use to him. In this article I have tried to put together all pieces of evidence to prove that the King really was shot. This includes old tales as well as written evidence and facts brought to light during the latest examination of King Erik's remains. This investigation was done in 1958 by professor Carl-Herman Hjortsjö and his collaborators. At the opening of the sarcophagi a defect healed fracture on the left humerus was still clearly visible. Many facts in this article originate from works by L.-I. Jönsson who in a very thorough and accurate way tried to reconstruct this interesting and exciting historical crime. PMID:11624765

    The work and legacy of Erik Erikson are described in this brief outline of his career, his theories, and his impact on psychoanalysis, psychology, history, and the broader culture. His conception of the adolescent task-weaving internal tastes, talents, and values together with elements of one's life history and the demands of one's culture into a coherent identity-has had profound effects on developmental psychology and the way in which sophisticated youth construct and describe their lives. His extension of development through adulthood and old age established the field of life course development. His emphasis on the impact of history and culture on development was a critical element in the developing field of ego psychology. Many of his major contributions can be fruitfully understood in the context of his personal history and individual qualities. PMID:9256525

    In his psychohistorical biographies of Luther and Gandhi, Erik Erikson proposed that great issues of a particular time and place, as experienced by sensitive and creative individuals who are working to resolve their inner conflicts within these contexts, could find solutions that transcend themselves and yield conceptualizations that transform the world. Although Erikson was able to create a conceptualization of the adolescent task of establishing a coherent identity, one that gave voice to the aspirations and frustrations of the rebellious student movements of the 1960s, he was never able, over his lifetime, to resolve his own identity issues. Was he Dane or German, American or Scandinavian, Jew or Christian or both? His lifelong back-and-forths on this struggle are chronicled.

    Kivnick, Helen Q; Wells, Courtney K

    2014-02-01

    Erik H. Erikson published his groundbreaking theory of 8 stages of lifelong psychosocial development in 1950. His theory expanded psychoanalytic concepts of psychosexual development to include the importance of social dynamics; it transcended then-current thinking that psychological development culminated in early adulthood, acknowledging that systematic human development continues throughout the entire life cycle. The theory made Erikson a pioneer in developmental psychology. His last authored book, Vital Involvement in Old Age, rearticulated and elaborated 3 principles that, in different words, are rooted in his original theory of healthy life cycle development: (1) Dynamic Balance of Opposites; (2) Vital Involvement; and (3) Life in Time. Using a lens informed by knowledge gained over the past 30 years and by reflections of one of the original researchers on that project, the current manuscript seeks to spark new interest in Erikson's late-life contribution. It explains the principles in new detail, links them to relevant research, and suggests ways they could enable Erikson's ideas to further enrich gerontological practice and research.

    PubMed

    2011-12-01

    This article makes the case that Erik H. Erikson developed a form of psychoanalytic discourse-the verbal portrait-which, although not unprecedented, became a focal feature of his work, and the testing ground for the cogency of his major contribution to psychoanalysis (the concept of identity). It suggests that Erikson was inspired to develop the verbal portrait because he came to psychoanalysis from art and was, in fact, a portrait artist. Drawing especially on the work of Richard Brilliant, it presents the view that a portrait is a portrayal of the subject's identity and goes on to show how Erikson's memorial to the cultural anthropologist Ruth Benedict is representative of the verbal portrait.

    2008-09-01

    Erik H. Erikson wrote three articles when he was in his late-twenties and an up-and-coming member of the psychoanalytic community in Vienna. At the time he wrote these articles, he was in a training psychoanalysis with Anna Freud, teaching at the Heitzing School in Vienna, and learning the Montessori method of teaching. These articles focus on the loss of primary narcissism and the development of the superego (or punitive conscience) in early childhood, especially through the child's conflict with maternal authority. They support the idea that melancholia, with its internalized rage against the mother, is the inevitable outcome of the loss of primary narcissism. I note, however, that the third of these articles makes a case for the restorative role of humor, especially when Freud's view that humor is a function of the superego is taken into account.

  17. [Erik Vio, surgeon from Rijeka at history's crossroad].

    PubMed

    Lazzarich, Marinko

    2016-08-01

    The fact that many famous denizens of Rijeka belong to different nationalities confirms this city's historic multicultural image. The life story of Erik Vio (1910-1966), renowned surgeon of international reputation, reflects the fate of many displaced residents of Rijeka who left to live in exile. After graduating in Rome, Vio worked as a medical doctor in Hong Kong for almost three decades. The question is weather a surgeon from Rijeka chose to live in Hong Kong because it reminded him of his hometown? The author finds the root of this thesis in Vio's novel The Pathways of Freedom (˝Irwege der Freiheit˝, Köln 1978), a particular medical-philosophic diagnosis of the contemporary civilization's spiritual state. Rare fragments dedicated to Rijeka confirm Vio's actual detachment; faced with his own identity, but also with the others' with whom he shared his living space, a surgeon from Rijeka became a true citizen of the world and at the same time a stateless person with no roots of his own. Through the projection of Hong Kong one can detect the novel's identification backbone: writer's provocation of the ideological perspective on socio-cultural relations. By engaging in the interpretation of Vio's The Pathways of Freedom the author seeks to dissect a sociological dimension of descriptions of dual identities in border space. This leads to the issue of understanding and tolerance toward the others. PMID:27598959

  2. The mother relationship and artistic inhibition in the lives of Leonardo da Vinci and Erik H. Erikson.

    PubMed

    Capps, Donald

    2008-12-01

    In four earlier articles, I focused on the theme of the relationship of melancholia and the mother, and suggested that the melancholic self may experience humor (Capps, 2007a), play (Capps, 2007b), dreams (Capps, 2008a), and art (Capps, 2008b) as restorative resources. I argued that Erik H. Erikson found these resources to be valuable remedies for his own melancholic condition, which had its origins in the fact that he was illegitimate and was raised solely by his mother until he was three years old, when she remarried. In this article, I focus on two themes in Freud's Leonardo da Vinci and a memory of his childhood (1964): Leonardo's relationship with his mother in early childhood and his inhibitions as an artist. I relate these two themes to Erikson's own early childhood and his failure to achieve his goal as an aspiring artist in his early twenties. The article concludes with a discussion of Erikson's frustrated aspirations to become an artist and his emphasis, in his psychoanalytic work, on children's play.

  4. Threshold of the volcanic forcing that leads the El Niño-like warming in the last millennium: results from the ERIK simulation

    2016-06-01

    In order to examine the threshold of the volcanic forcing that leads to the El Niño-like warming, we analyze a millennium ERIK simulation (AD 1000-1850) forced by three external forcings including greenhouse gases, solar forcing and volcanic eruptions using the ECHO-G coupled climate model. It is found that there exists a threshold of the volcanic forcing above 15 W/m2 to lead the El Niño-like warming in the climate model. When the volcanic forcing is above this threshold forcing, then the intensity of the Inter-tropical Convergence Zone (ITCZ) is weakened and its position is shifted to the south. This might be associated with the processes of less evaporation in the subtropical cloudless region by a cooling due to the reduction of net surface shortwave radiation. Concurrently, a weakening of ITCZ is associated with a weakening of the trade winds and the subsequent Bjerknes feedback causes El Niño-like warming. Therefore, El Niño-like warming events can occur when volcanic eruption is above threshold forcing, implying that there exists a certain level of radiative forcing change which is capable of changing the state of tropical Pacific sea surface temperature. The last millennium simulation of Paleoclimate Modeling Intercomparison Project Phase 3 climate models also indicates that there may exist a threshold forcing to lead the El Niño-like warming, which has been also discussed in the present study.

  5. Multi-proxy evidence for climate and North Atlantic Deep Water variability spanning the mid to late Holocene at the Erik sediment drift

    NASA Astrophysics Data System (ADS)

    2012-12-01

    The origin of Holocene abrupt climate changes like the 8.2 ka BP event, the 4.2 ka BP anomaly and the Little Ice Age, and in particular the role of ocean dynamics in these events, is a matter of considerable debate. The paucity of marine records capable of portraying both climate and North Atlantic Deep Water (NADW) properties during these anomalies has confounded efforts to determine how, or even if, deep ocean ventilation changed at these times. To elucidate the timing, magnitude, and nature of climate and deep-water changes spanning the mid to late Holocene we have generated a suite of high-resolution multi proxy records in cores MD03-2665 and GS06-144-MC03 (57°26.56N, 48°36.60W, 3440 m water depth) from the Erik Drift. The Holocene in this core is represented by ~5.6 m of sediment, and previous studies (Kleiven et al., 2008) demonstrate that the site is sensitively situated and provides the temporal fidelity to detect abrupt climate and deep circulation events. We reconstruct the bottom water physical and chemical properties of the deep overflowing branches from the Nordic Seas using oxygen and carbon isotopes of benthic foraminifera, whereas changes in the vigor of near bottom flow are inferred from size variations in mean sortable silt. Changes in North Atlantic hydrography are portrayed using records of planktonic foraminiferal isotopes and assemblage counts, ice-rafted debris counts, as well as modern analog technique sea surface temperature estimations. Major elements are also obtained throughout the core by XRF scanning. The planktonic foraminiferal oxygen isotopic and sea surface temperature reconstructions from 7 to 0 ka BP exhibit a distinct sequence of multi-centennial to millennial-scale cooling events. The first of these prominent coolings that characterize the late Holocene is initiated ~4.6 ka BP, and culminates at 4.0 ka BP. Similarly strong coolings occur between 2.9-2.5ka and at the onset of the Little Ice Age at ~0.5 ka BP (1450 AD). Many of

  9. Homosexual mutuality: variation on a theme by Erik Erikson.

    PubMed

    Sohier, R

    The exploratory descriptive study described here was conducted in order to produce the initial empirical evidence to support reformulation of the theoretical construct of heterosexual mutuality (Erikson, 1975). Six persons were interviewed in depth on tape in order to locate them on one of four identity statuses constructed by Marcia (1964, 1966, 1973). The tool was modified and extended to meet the purposes of the study. The questions are directed toward illumination of conflictual moments in the life cycle when the ability to make appropriate decisions engenders character growth, and supports the personality integration of adulthood. An ability to make decisions results in personality integration. The small study provides evidence that there exists a homosexual mutuality (contrary to Erikson's position) which is no less valuable than heterosexual mutuality, and forms an equal basis for adult personality integration.

    This anniversary Classic Text, the 'Introduction' from Strömgren's 'Episodic Psychoses', provides a comprehensive, concise and erudite exposition of the history, nosography and nosology of these conditions. Strömgren traces the origin of this term and concepts back to Magnan's degeneration psychoses and associated 'syndromes épisodiques'. Especially inspired by 'the psychogenic psychosis' (1916), the seminal work by his mentor, August Wimmer, he convincingly shows that the episodic psychoses constitute an intermediate link between the degeneration psychoses, now an obsolete term, and the psychogenic psychoses, reactive psychoses and brief reactive psychoses, which in their own right have been a bone of contention in international psychiatry for many decades and an obstacle in achieving consensus in international psychiatric classification.

    The author reconsiders Erikson's 'Dream specimen' paper as a forerunner of subsequent reader-response criticism, constructive writings on the exploration of countertransference and our contemporary debates about the constructions of meaning in the analytic and literary situations. He regards Erikson as deconstructing our interpretive efforts with texts and with patients; we are to move away from an interpretive process in which we pin down meanings towards opening up the ongoing exploration of multiple meanings. By emphasising self-reflexive questioning and joyful play between texts and readers and analysands and analysts, Erikson contributed to opening up the pleasures of both psychoanalysis and literary criticism. Although he wonders whether Erikson may have wished to move his own creativity beyond conflict, the author heartily endorses his encouraging us to enjoy playing with our materials--texts, dreams and analyses.

  20. A "Curling teacher" in mathematics education: teacher identities and pedagogy development

    NASA Astrophysics Data System (ADS)

    Andersson, Annica

    2011-12-01

    In this article, I outline processes that supported or hindered Elin, a mathematics teacher, to engage in pedagogy development. In a setting inspired by critical mathematics education, Elin was encouraged to bring societal themes into her upper secondary teaching so that mathematics was connected to social science subjects. A classroom environment was set up in which classroom discourses supported students' negotiations about their learning of mathematics. In this new pedagogical discourse, projects were introduced that while addressing the mandated mathematical topics of the curriculum, changed some key elements in how mathematics had been previously taught as well as the relationships between participants. Elin's narrated identities provided ways to understand shifts in Elin's ways of acting when gradually transforming her teaching. Elin's identities illuminated how she became aware of herself, her teaching organisation and her different ways of interacting with students. She identified and acted upon her perceptions of the new possibilities and different responsibilities that actors in mathematics classrooms have. Elin's fluctuating teacher identities reveal why she struggled at times and how she was constrained in becoming the teacher she wanted to become.

    1987-07-01

    The Panasonic UD-801 TLDs used in the U.S. Nuclear Regulatory Commission's environmental monitoring program are calibrated using the Williston Elin Model 2001 Irradiator. This article describes the procedure used to calibrate this irradiator for the delivery of exposures in the range of 40 to 1200 mR. A select group of TLDs, another source, and an NBS-calibrated ion chamber were used to perform a secondary calibration of the WE-2001. Extraneous exposure contributions (background radiation from the irradiator's source and exposure occurring during TLD travel into and out of the irradiation chamber) were measured and evaluated. The WE-2001 TLD Irradiator was calibrated to a total uncertainty of {plus minus}3.2%; however, TLD travel time exposures were found to be quite significant for the short irradiation times typically used in environmental applications.

    The acute phase response is initiated in response to infection or physical trauma and is characterized by an increase in the levels of some plasma proteins. Here, Erik Hack and colleagues suggest that the combined actions of two of these acute phase proteins, secretory phospholipase A2 and C-reactive protein, may serve to promote phagocytosis of injured cells and tissue debris, thereby enhancing inflammation and tissue damage.

  18. Remote Correlation of Paleoceanographic Events in the Northern Parts of Bering and Barents Seas during the Termination I and Early Holocene

    Ivanova, E. V.; Ovsepyan, E.; Murdmaa, I.; de Vernal, A.; Risebrobakken, B.; Seitkalieva, E.; Radionova, E.; Alekhina, G.

    2014-12-01

    The Barents and Bering seas are closely linked to the High Arctic and to the THC by marine gateways as well as by land-sea and ocean-atmosphere interactions. Our multi-proxy time series demonstrate that these remote seas exhibited dramatic changes during the deglaciation through a succession of global and regional paleoceanographic events including the beginning of Termination I (BT1), Heinrich-1 or Oldest Dryas (OD), Bølling-Allerød (B/A), Younger Dryas (YD) and early Holocene (EH). In the NW Barents Sea, the increased subsurface-to-bottom Atlantic water inflow via the Kvitøya-Erik Eriksen trough (cores S 2519 and S 2528) is inferred at the late OD, late B/A and late YD/EH transition. These events are generally coupled with the strengthened AMOC. A remarkable sea surface warming and sea ice retreat are documented at ~ 13 ka BP. Surface warming and strong Atlantic water inflow were followed by intense iceberg calving in the Erik Eriksen Trough as indicated by the high IRD content of Core S-2519. The rock fragments are unsorted and mainly angular suggesting their ice-rafted (likely iceberg-rafted) origin. Svalbard glaciers apparently derived the material dominated by black schistous mudstones, hard limestones with coral remains, fine-grained sandstones from nearby islands, and icebergs spread it in the Kvitøya-Erik Eriksen Trough during the early deglaciation. The ice rafted coarse terrigenous material supply during the BT1 is also suggested for the NW Bering Sea. In the NW Pacific, NW Bering Sea and Sea of Okhotsk, surface bioproductivity peaked at B/A and EH mainly due to the global warming, enhanced nutrient supply by surface currents from the flooded northeastern shelf, intensified vertical mixing and water exchange through the opened straits. Oxygen-depleted bottom water at intermediate depths characterized several locations including the NW Bering Sea (Core SO201-2-85KL).

    The focus of this paper is on the adult who has adequately mastered the oedipal stage of psychosexual development and who presents with a sexual dysfunction. Drawing on the developmental sequence of Erik Erikson, the authors suggest that failure to address adequately an adult psychosocial crisis may result in sexual dysfunction. There may be both adult developmental deficits and regression to adolescent and adult stages previously negotiated. Both may be symptomatically represented by sexual dysfunction. The authors urge that the sexual and marital problems be evaluated within an adult developmental framework and that the therapy address the psychosocial issues which are appropriate to the developmental stage of the patient.

    Joan M. Erikson (1902-1997) was an artist, a writer, a mother, and the wife and collaborator of Erik H. Erikson (1902-1994), one of the most important and influential psychoanalysts in the world. The following is an edited dialogue on one of her favorite topics--The Importance of Play in Adulthood. It features her thoughts on the subject and reminiscences of the ways she played throughout her life. She muses on play in relation to humor, fun, the role of the fool, and more. The article was a project undertaken in the spirit of play and it will hopefully evoke further playful musings in the minds of readers.

    The spiritual journey of a Buddhist devotee is a continual exploration of the truth of interdependence which Siddhartha Gautama realized to become the Buddha, "the Enlightened One." On the morning of the enlightenment, the Buddha apprehended the truth that all things and all beings are interconnected and mutually dependent in time and space. One measure of the spiritual maturity of the Buddhist devotee is his or her appreciation for the profound responsibilities and gratitude we share for all things. To illustrate the significance of interdependence in our lives, the author turns to the wisdom contained inVital Involvement in Old Age by Erik and Joan Erikson and Helen Q. Kivnick.

    1992-09-01

    Engendering family life is a spiritual process (theosis) based on human ethological constants of gender difference and generational turnover. Recent studies on ethnicity suggest that such a process retrieves a primordial sense of the human species as a whole, "humankind." Families, especially in this broad sense, link together the living and the dead and, at their best, morally empower individuals who link their destinies to such a vision of creation and human health. Reference is made to work on human strengths and speciation by Erik Erikson and to that on maternal thinking by Sara Ruddick. A political program by which an ideology of "familism" can be made is offered.

    How can subordinates improve relations with their superiors? And how can superiors help their subordinates feel comfortable in what is often a tense relationship? These questions have usually been dealt with only indirectly in management circles. Yet the relationship is so threatening to many subordinates that they react in ways that are damaging to themselves and their ogranizations. Drawing heavily on the work of psychologist Erik Erikson, the authors present dilemmas that commonly confront the subordinate. They point out that being aware of these dilemmas can make them more manageable and then offer advice to superiors to aid subordinates in handling such situations.

    Akira Kurosawa's 1952 film about a man with a terminal gastric cancer introduces a discussion of hope and faith in the oncology patient. A psychodynamic relationship between hope and faith is explored, using Lawrence LeShan's research in cancer psychotherapy and Erik Erikson's lifespan developmental theory. LeShan describes a cancer personality characterized by hopeless despair, while Erikson formulates a psychogenetic framework for the development of hope and despair. Hope and faith are linked through the individual's earliest strivings toward basic trust in the world and his or her own self-efficacy. Accordingly, cancer psychotherapy may aim at restoring adult patients' faith in life and inner creative resources.

    In this article, Erik Erikson's and subsequent researchers' ideas on generativity are applied to "the clerical abuse crisis," in which 111 U.S. Roman Catholic bishops protected priests rather than safeguard children. The goal was to discover what psychological dispositions led bishops to act in the manner they did. A case is made that pre-existing tendencies coupled with an all-male, celibate environment and formation indoctrination led to deficits in psychological development, moral judgment and leadership capacity, revealing an Episcopal subculture characterized by pseudo-speciation and authoritism.

    In a recent publication, Erik Verlinde attempts to show that gravity should be viewed not as a fundamental force, but rather as an emergent thermodynamic phenomenon arising from an unspecified microscopic theory via equipartition and holography. We present a challenge to his reformulation of gravity. A detailed examination of Verlinde's derivation leads to a number of questions that severely weaken the claim that such a theory correctly reproduces Newton's laws or Einstein gravity. In particular, we find that neither Newtonian gravity nor the Einstein equations are uniquely determined using Verlinde's postulates.

    As the USA Health Care System undergoes transformation and transitions to value-based models it is critical for laboratory medicine/clinical pathology physicians to explore opportunities and find new ways to deliver value, become an integral part of the healthcare team. This is also essential for ensuring financial health and stability of the profession when the payment paradigm changes from fee-for-service to fee-for-performance. About 5 years ago we started searching for ways to achieve this goal. Among other approaches, the search included addressing the laboratory work-ups for specialists' referrals in the HarrisHealth System, a major safety net health care organization serving mostly indigent and underserved population of Harris County, TX. We present here our experience in improving the efficiency of laboratory testing for the referral process and in building a prototype of a diagnostic e-consult service using rheumatologic diseases as a starting point. The service incorporates algorithmic testing, integration of clinical, laboratory and imaging data, issuing structured comprehensive consultation reports, incorporating all the relevant information, and maintaining personal contacts and an e-line of communications with the primary providers and referral center personnel. Ongoing survey of providers affords testimony of service value in terms of facilitating their work and increasing productivity. Analysis of the cost effectiveness and of other value indicators is currently underway. We also discuss our pioneering experience in building pathology residents and fellows training in integrated diagnostic consulting service.

  16. An improved method of measuring tropospheric NO2, NO3, HO2, and RO2 by Matrix Isolation and Electronic Spin Resonance (MIESR)

    NASA Technical Reports Server (NTRS)

    1994-01-01

    The MIESR method consists of two steps (1) collection of the radicals present in the ambient air at 77K in a polycrystalline D2O matrix and (2) identification and quantification of the different radicals in the laboratory by Electron Spin Resonance spectroscopy. In step (1), the sampling efficiency for sampling NO2 and RO2 was determined to be greater than or equal to 95 percent, with a measured accuracy of plus or minus 5 percent. In step (2), after collection, the samples are maintained at 77 K and spectra are recorded in the laboratory using a standard 9.5 GHz ESR system (Varian E-line). About 50 individual scans of each spectrum are recorded and digitally averaged in order to improve the signal-to-noise ratio. The ESR-spectra are analyzed with a recently developed numerical procedure which was demonstrated to allow speciation of NO2, NO3, HO2, CH3C(O)O2, and the sum of the alkylperoxy radicals. The detection limit is 5ppt for HO2, RO2, and NO2 and 3ppt for NO3 due to its narrower ESR-linewidth.

    Sole carbon source utilization (SCSU) patterns and phospholipid fatty acid (PLFA) profiles were compared with respect to their potential to characterize root-inhabiting microbial communities of hydroponically grown crops. Sweet pepper (Capsicum annum cv. Evident), lettuce (Lactuca sativa cv. Grand Rapids), and four different cultivars of tomato (Lycopersicon esculentum cvs. Gitana, Armada, Aromata, and Elin) were grown in 1-L black plastic beakers placed in a cultivation chamber with artificial light. In addition to the harvest of the plants after 6 weeks, plants of one tomato cultivar, cv. Gitana, were also harvested after 4 and 8 weeks. The cultivation in this study was performed twice. Principal component analysis was used to analyze the data. Both characterization methods had the ability to discriminate between the root microflora of different plant species, cultivars, and one tomato cultivar at different ages. Differences in both SCSU patterns and PLFA profiles were larger between plant species than between cultivars, but for both methods the largest differences were between the two cultivations. Still, the differences between treatments were always due to differences in the same PLFAs in both cultivations. This was not the case for the SCSU patterns when different plant ages were studied. Furthermore, PLFA profiles showed less variation between replicates than did SCSU patterns. This larger variation observed among the SCSU data indicates that PLFA may be more useful to detect changes in the root microflora of hydroponically grown crops than the SCSU technique.

    In recent years new challenges have emerged in the telecommunications market resulting from the increase of network traffic and strong competition. Because of that, service providers feel constrained to replace expensive and complex IP-routers with a cheap and simple solution which guarantees the requested quality of services (QoS) with low cost. One of these solutions is to use the Ethernet technology as a switching layer, which results in using the cheap Ethernet services (E-Line, E-LAN and E-Tree) and to replace the expensive IP-routers. To achieve this migration step, new algorithms that support the available as well as the future services have to be developed. In this paper, we investigate the multicast protection issue. Three multicast protection algorithms based on the shared capacity between primary and backup solutions are proposed and evaluated. The blocking probability is used to evaluate the performance of the proposed algorithms. The sub-path algorithm resulted in a low blocking probability compared with the other algorithms.

    During the summer of 1979, geophysical work was done in the Lassen KGRA in northeastern California to assess the geothermal potential of the area. As part of the study, 68 audio-magnetotelluric (AMT) soundings were made and 2 telluric and self-potential (SP) profiles were done. The AMT station locations are shown. The scalar resistivities were contoured for 7.5 and 27 hertz data at north-south and east-west E-line orientations. The contour maps are complex, reflecting both lateral changes in geology and geothermal activity. The locations of the telluric and self-potential traverses are given. The profiles for traverse 1 show varied SP and telluric responses. The variations are probably geologically related with the drop in SP voltage and telluric resistivity on the east end of the traverse caused by a lateral lithology change. The profiles for traverse 2 show a sharp drop in SP voltage combined with a sharp increase in telluric resistivity near station 6. This could be associated with large-scale intrusive features (a ring dike) which trend to the northwest.

    In many Nordic countries more than half of the drinking water is produced using surface water. Artificial infiltration allows increasing water withdrawal from groundwater but may not be sustainable during longer periods. Here we report results from a one year study on changes in dissolved organic carbon concentration (DOC) and DOC character along the whole infiltration area starting with the stream water until the drinking water plant raw water intake. Both DOC, fluorescence spectroscopy and LC-OCD are used to understand the observed changes in the aquatic phase. Large seasonal changes close to the infiltration basin contrasts with stable conditions further away. Selective removal of terrestrial type of DOC is coherent using both analytical techniques. A simple empirical relationship between Humic like material and absorbance developed elsewhere also holds in this system (Köhler et al 2016). Fluorescence is a fast and promising tool for tracking changes in natural organic carbon character during artificial infiltration. References Stephan J.

    We study experimentally electron transport in 1 dimensional semiconductor nanowires (consisting of InAs and InP combinations) and carbon nanotubes. The wires are connected to superconducting source-drain contacts with gate electrodes in the substrate or on the surface. In the regime of weak coupling to the contacts we observe Coulomb blockade effects. We present level spectroscopy including a determination of the spin states. In the regime of strong coupling to the contacts interference effects are observed. In this regime and using superconducting contacts, we find supercurrents flowing through InAs-nanowires over micrometer length scales. The critical current is tunable by gate voltage, thus realizing so-called JOFETs (Josephson FETs) [1]. When we define quantum dots in between superconducting contacts the direction of the supercurrent is determined by the single electron spin state in the quantum dot [2,3]. 1.

    Accurate and complete reporting of study methods, results and interpretation are essential components for any scientific process, allowing end-users to evaluate the internal and external validity of a study. When animals are used in research, excellence in reporting is expected as a matter of continued ethical acceptability of animal use in the sciences. Our primary objective was to assess completeness of reporting for a series of studies relevant to mitigation of pain in neonatal piglets undergoing routine management procedures. Our second objective was to illustrate how authors can report the items in the Reporting guidElines For randomized controLled trials for livEstoCk and food safety (REFLECT) statement using examples from the animal welfare science literature. A total of 52 studies from 40 articles were evaluated using a modified REFLECT statement. No single study reported all REFLECT checklist items. Seven studies reported specific objectives with testable hypotheses. Six studies identified primary or secondary outcomes. Randomization and blinding were considered to be partially reported in 21 and 18 studies, respectively. No studies reported the rationale for sample sizes. Several studies failed to report key design features such as units for measurement, means, standard deviations, standard errors for continuous outcomes or comparative characteristics for categorical outcomes expressed as either rates or proportions. In the discipline of animal welfare science, authors, reviewers and editors are encouraged to use available reporting guidelines to ensure that scientific methods and results are adequately described and free of misrepresentations and inaccuracies. Complete and accurate reporting increases the ability to apply the results of studies to the decision-making process and prevent wastage of financial and animal resources.

    AIDS has a unique set of characteristics that makes group psychotherapy more complex than with other populations: (1) the threat of an early death, (2) a highly variable course of illness, and (3) stigma related to the illness and to the preexisting lifestyles of most patients. The specific ways in which the three factors seriously interfere with establishing and maintaining group cohesion are discussed, and clinical guidelines are suggested. In addition, a model for understanding and working with these and other issues in group psychotherapy, based on Erik Erikson's interpersonal theory of development, is presented. Finally, particular countertransferential difficulties are discussed in relation to the heightened emotionality common to AIDS psychotherapy groups. PMID:1938017

    Generativity is a concept first introduced by Erik Erikson as a part of his psychosocial theory which outlines eight stages of development in the human life. Generativity versus stagnation is the main developmental concern of middle adulthood; however, generativity is also recognized as an important theme in the lives of older adults. Building on the work of Erikson, McAdams and de St. Aubin (1992) developed a model explaining the generative process. The aims of this article are: (a) to explore the relationship between generativity and older adults as it appears in research literature; and (b) to examine McAdam's model and use it to explain the role of generativity in older adults who share life stories with gerontology students through an oral history project.

    Career changes in all vocations are relatively common in the forties age group due to a variety of factors which include a crisis period caused by polarities of Generativity versus Stagnation as conceptualized by Erik H. Erikson. Generativity is served not only by procreativity but also by guiding the next generation through teaching. The result can be the strength of Care. Stagnation can result in unhappiness, irrational and destructive behavior, or withdrawal. Concepts of young, old and mortality also come into focus. A successful career change from private practice to academic medicine depends upon a combination of power, opportunity, and character. To be successful, the change should be made for positive reasons and be based upon youthful concepts in the cold reality of the financial and intellectual challenges of a new and competitive career. If properly done, both the personal rewards and the contribution to future medical care can be quite positive.

  7. From Cicero to Cohen: developmental theories of aging, from antiquity to the present.

    2014-02-01

    Cicero's famous essay "On Old Age," written in ancient Rome, was one of the first detailed depictions of the challenges and opportunities posed by the aging process. Several modern developmental theories of the life cycle have echoed many of the themes of Cicero, including the existence of unfolding life stages with specific tasks and transitions. Freud's psychoanalytic theory of infantile sexuality provided a limited starting point, as well as a theoretical base for Erik Erikson's proposed eight stages of the life cycle. Unlike Freud, however, Erikson and others including Daniel Levinson, George Vaillant, and Carol Gilligan elaborated on forces in adult development that were distinct from early life experiences. Gene Cohen's theory of human potential phases took middle age as a starting point and proposed an extensive structure for late-life development based on emergent strengths including wisdom and creativity.

  8. On the origins of psychoanalytic psychohistory.

    2003-05-01

    This article examines the origins and early development of psychoanalytically inspired psychohistory from the late 1950s to the early 1970s. It focuses on Erik H. Erikson, Bruce Mazlish, and Robert Jay Lifton and illustrates their contributions to psychoanalytic psychohistory. Erikson, Mazlish, and Lifton were core members of the Wellfleet group, a research project originally funded by the American Academy of Arts and Sciences in 1965 to conceptualize the foundation of psychohistory. The article gives an account of the early history of the Wellfleet group and argues for specific historical reasons to explain why psychoanalytic psychohistory emerged on the East Coast of the United States in the late 1950s and early 1960s. A critique of the Wellfleet group in unpublished correspondence of Erich Fromm and David Riesman is also discussed.

    1988-04-01

    Theoretical assumptions outlined by Erik Erikson on psychosocial crisis resolution hypothesizes that the positive resolution of the identity crisis is predictive of more mature intimacy formation. To test this hypothesis, college-aged late adolescents (48 subjects) completed interviews and selfreport instruments measuring identity formation and degree of intimacy along with daily records of social interactions for one week. Analyses indicated a complex association between identity and intimacy formation. Comparisons were made between the exploration and commitment process of identity and the measures of intimacy formation and social interaction measures. Numerous complex sex differences were observed with several interactions between gender, exploration, commitment, and intimacy context. Findings are discussed in terms of broadening future research direction beyond the simple study of the linkage of identity and intimacy.

    Hematopoietic stem cell transplantation (HSCT) is a widely practiced therapy for many life-threatening childhood disorders. The authors investigated the psychosocial effects of HSCT on siblings of pediatric HSCT patients (n = 44; 21 donors, 23 nondonors, ages 6 to 18 years). Donor siblings reported significantly more anxiety and lower self-esteem than did nondonors. Nondonors showed significantly more school problems. Approximately one third of all siblings reported moderate to severe posttraumatic stress. The study drew on the developmental theory of Erik Erikson and the psychosocial model of posttraumatic stress. As part of the study, the authors used the Measures of Psychosocial Development (MPD), a self-report measure based on Eriksonian constructs. The MPD was used to assess the psychosocial adjustment of 12 siblings who were adolescents (> or =13 years) at the time the study was conducted. In this article, findings are presented from the MPD as well as salient findings from the larger study.

The human development stages described by Erik Erikson are used to compare the growth stages of these two groups to the human sequence. It is hypothesized that both female-dominated groups began with an "infancy" period in the early 1900s characterized by the beginnings of identity and confidence in their respective groups. Both continued to develop through stages corresponding to the childhood stages characterized by Erikson and into the adolescent acting out stages as characterized by the demonstrations of the 1960s. Present and future trends are explored in relation to developmental stages, as well as to implications for the field of occupational therapy in education, theory, and practice.

  12. The application of a generativity model for older adults.

    Generativity is a concept first introduced by Erik Erikson as a part of his psychosocial theory which outlines eight stages of development in the human life. Generativity versus stagnation is the main developmental concern of middle adulthood; however, generativity is also recognized as an important theme in the lives of older adults. Building on the work of Erikson, McAdams and de St. Aubin (1992) developed a model explaining the generative process. The aims of this article are: (a) to explore the relationship between generativity and older adults as it appears in research literature; and (b) to examine McAdam's model and use it to explain the role of generativity in older adults who share life stories with gerontology students through an oral history project.

    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 article 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.

    In the New York Times bestselling book The Game: Penetrating the Secret Society of Pickup Artists (2006), the world was granted its first exclusive introduction to the steadily growing dating coach and pick-up artist community. Many of its most prominent authorities claim to use insights and information gleaned both through first-hand experience as well as empirical research in evolutionary psychology. One of the industry's most well-respected authorities, the illusionist Erik von Markovik, promotes a three-phase model of human courtship: Attraction, building mutual Comfort and Trust, and Seduction. The following review argues that many of these claims are in fact grounded in solid empirical findings from social, physiological and evolutionary psychology. Two texts which represent much of this literature are critiqued and their implications discussed. PMID:23253794

    Hematopoietic stem cell transplantation (HSCT) is a widely practiced therapy for many life-threatening childhood disorders. The authors investigated the psychosocial effects of HSCT on siblings of pediatric HSCT patients (n = 44; 21 donors, 23 nondonors, ages 6 to 18 years). Donor siblings reported significantly more anxiety and lower self-esteem than did nondonors. Nondonors showed significantly more school problems. Approximately one third of all siblings reported moderate to severe posttraumatic stress. The study drew on the developmental theory of Erik Erikson and the psychosocial model of posttraumatic stress. As part of the study, the authors used the Measures of Psychosocial Development (MPD), a self-report measure based on Eriksonian constructs. The MPD was used to assess the psychosocial adjustment of 12 siblings who were adolescents (> or =13 years) at the time the study was conducted. In this article, findings are presented from the MPD as well as salient findings from the larger study. PMID:15490868

    Theoretical assumptions outlined by Erik Erikson on psychosocial crisis resolution hypothesizes that the positive resolution of the identity crisis is predictive of more mature intimacy formation. To test this hypothesis, college-aged late adolescents (48 subjects) completed interviews and selfreport instruments measuring identity formation and degree of intimacy along with daily records of social interactions for one week. Analyses indicated a complex association between identity and intimacy formation. Comparisons were made between the exploration and commitment process of identity and the measures of intimacy formation and social interaction measures. Numerous complex sex differences were observed with several interactions between gender, exploration, commitment, and intimacy context. Findings are discussed in terms of broadening future research direction beyond the simple study of the linkage of identity and intimacy. PMID:24277583

  19. From Cicero to Cohen: developmental theories of aging, from antiquity to the present.

    Agronin, Marc E

    2014-02-01

    Cicero's famous essay "On Old Age," written in ancient Rome, was one of the first detailed depictions of the challenges and opportunities posed by the aging process. Several modern developmental theories of the life cycle have echoed many of the themes of Cicero, including the existence of unfolding life stages with specific tasks and transitions. Freud's psychoanalytic theory of infantile sexuality provided a limited starting point, as well as a theoretical base for Erik Erikson's proposed eight stages of the life cycle. Unlike Freud, however, Erikson and others including Daniel Levinson, George Vaillant, and Carol Gilligan elaborated on forces in adult development that were distinct from early life experiences. Gene Cohen's theory of human potential phases took middle age as a starting point and proposed an extensive structure for late-life development based on emergent strengths including wisdom and creativity.

    1984-03-01

    Career changes in all vocations are relatively common in the forties age group due to a variety of factors which include a crisis period caused by polarities of Generativity versus Stagnation as conceptualized by Erik H. Erikson. Generativity is served not only by procreativity but also by guiding the next generation through teaching. The result can be the strength of Care. Stagnation can result in unhappiness, irrational and destructive behavior, or withdrawal. Concepts of young, old and mortality also come into focus. A successful career change from private practice to academic medicine depends upon a combination of power, opportunity, and character. To be successful, the change should be made for positive reasons and be based upon youthful concepts in the cold reality of the financial and intellectual challenges of a new and competitive career. If properly done, both the personal rewards and the contribution to future medical care can be quite positive. PMID:6706448

    This article examines the origins and early development of psychoanalytically inspired psychohistory from the late 1950s to the early 1970s. It focuses on Erik H. Erikson, Bruce Mazlish, and Robert Jay Lifton and illustrates their contributions to psychoanalytic psychohistory. Erikson, Mazlish, and Lifton were core members of the Wellfleet group, a research project originally funded by the American Academy of Arts and Sciences in 1965 to conceptualize the foundation of psychohistory. The article gives an account of the early history of the Wellfleet group and argues for specific historical reasons to explain why psychoanalytic psychohistory emerged on the East Coast of the United States in the late 1950s and early 1960s. A critique of the Wellfleet group in unpublished correspondence of Erich Fromm and David Riesman is also discussed. PMID:12822567

    Leaf rust (Puccinia triticina Eriks.), stripe rust (Puccinia striiformis f. tritici Eriks.) and stem rust (Puccinia graminis f. sp. tritici) cause major production losses in durum wheat (Triticum turgidum L. var. durum). The objective of this research was to identify and map leaf, stripe and stem rust resistance loci from the French cultivar Sachem and Canadian cultivar Strongfield. A doubled haploid population from Sachem/Strongfield and parents were phenotyped for seedling reaction to leaf rust races BBG/BN and BBG/BP and adult plant response was determined in three field rust nurseries near El Batan, Obregon and Toluca, Mexico. Stripe rust response was recorded in 2009 and 2011 nurseries near Toluca and near Njoro, Kenya in 2010. Response to stem rust was recorded in field nurseries near Njoro, Kenya, in 2010 and 2011. Sachem was resistant to leaf, stripe and stem rust. A major leaf rust quantitative trait locus (QTL) was identified on chromosome 7B at Xgwm146 in Sachem. In the same region on 7B, a stripe rust QTL was identified in Strongfield. Leaf and stripe rust QTL around DArT marker wPt3451 were identified on chromosome 1B. On chromosome 2B, a significant leaf rust QTL was detected conferred by Strongfield, and at the same QTL, a Yr gene derived from Sachem conferred resistance. Significant stem rust resistance QTL were detected on chromosome 4B. Consistent interactions among loci for resistance to each rust type across nurseries were detected, especially for leaf rust QTL on 7B. Sachem and Strongfield offer useful sources of rust resistance genes for durum rust breeding.

    During the last 15 years, cleft lip and palate (CLP) patients with maxillary deficiency in the care of the Bergen CLP team have undergone an interceptive orthopedic treatment phase during the deciduous and mixed dentition period. The present study includes 68 patients who received maxillary transverse expansion by use of a modified quad-helix appliance and 98 cases given maxillary protraction by a facial mask. All cases were treated until an acceptable normal occlusion was attained. Lateral cephalograms were taken immediately before and after the active treatment periods. Sagittal changes of the soft-tissue profile during transverse expansion and protraction were analyzed separately for unilateral complete cleft lip and palate (UCLP) patients and bilateral complete cleft lip and palate (BCLP) patients. The soft-tissue profiles of the groups were compared to growth changes of noncleft age-matched children (NORM group). During the short period of maxillary transverse expansion (mean period, 3.5 months) no significant change of the soft-tissue profile was found, except in the protrusion of the lower lip in the BCLP group. During the period of maxillary protraction (mean periods, 12 months in the UCLP group and 15 months in the BCLP group) the soft-tissue profile improved significantly by reducing the characteristic tendency towards a concave profile in CLP patients with maxillary deficiency. Significant increases of the sagittal maxillomandibular lip relation (angle SS-N-SM: mean increase, 2.5 degrees) and the Holdaway-angle (H-angle: mean increase, 3.0 degrees) were found to be similar in the UCLP and BCLP groups. However, the use of different reference lines for evaluation of treatment effects upon the soft-tissue profile resulted in conflicting findings suggesting that anteriorly situated reference lines are more suitable for the evaluation of CLP patients. Thus, the esthetic line (E.line) indicated a favorable position of the lips after treatment; the subspinale

    This abstract will not blow you away, but speed-painting presenter Erik Wahl will certainly make a truly unique AAPM symposium that you will not want to miss. Along with clinical director John Bayouth and scientific leader Jeff Siewerdsen, this session will highlight innovation. To avoid being button pushers and irrelevant investigators of yesterday’s science, we must innovate. This is particularly challenging in the changing landscape of declining research funding and healthcare reimbursement. But all hope is not lost, Medical Physics is a field born out of innovation. As scientists we quickly translated the man-made and natural phenomena of radiation into a tool that could diagnose broken bones, locate foreign objects imbedded within the body, and treat a spectrum of diseases. As hyperbolae surrounding the curative powers of radiation overcame society, physicists continued their systematic pursuit of a fundamental understanding of radiation and applied their knowledge to enable the diagnostic and therapeutic power of this new tool. Health economics and the decline in research funding have put the Medical Physicist in a precarious position: how do we optimally participate in medical research and advanced patient care in the face of many competing needs? Today's diagnostic imaging and therapeutic approaches are tremendously sophisticated. Researchers and commercial vendors are producing technologies at a remarkable rate; to enable their safe and effective implementation Medical Physicists must work from a fundamental understanding of these technologies. This requires all of us, clinically practicing Medical Physicists, Researchers and Educators alike, to combine our training in scientific methods with innovation. Innovation is the key to our past, a necessity for our contemporary challenges, and critical for the future of Medical Physics. The keynote speakers for the 2014 AAPM Presidential Symposium session will address the way we approach these vitally important

    Erik Noji, mentioned, tongue in cheek, Noah as the first disaster manager during a lecture in 2005. The canonical description of "The Genesis Flood" does describe Noah as a master planner and executer of an evacuation of biblical proportions. After gaining knowledge of a potential catastrophic disaster he planned and executed an evacuation to mitigate the effects of the "Genesis Flood" by building the Ark and organizing a mass exodus. He had to plan for food, water, shelter, medical care, waste disposal and other needs of all the evacuees. Throughout history, management of large disasters was conducted by the military. Indeed, the military still plays a large role in disaster response in many countries, particularly if the response is overseas and prolonged. The histories of emergency preparedness, disaster management and disaster medicine have coevolved and are inextricably intertwined. While disaster management in one form or another existed as long as people started living together in communities, the development of disaster medicine took off with the emergence of modern medicine. Similar to disaster management, disaster medicine also has roots in military organizations.

    2002-01-01

    It all started in 1950 with the introduction of the first commercially available electromyography (EMG) system. From 1950 to 1973 was the era of the analog EMG systems: EMG signals were recorded, and subsequent analyses were carried out manually on film or paper. From 1973 to 1982, the first modular digital EMG systems were introduced. Dedicated analysis modules were introduced, but detailed analysis was still done on paper. In 1982, the first system controlled by a microprocessor was introduced. From 1982 to 1993, many new ways of analyzing EMG signals and basic reporting features were implemented in the EMG systems. Since 1993, personal computer technology has been used in EMG systems. Standard software and hardware components are used to record, analyze, and document EMG examinations. Since 1950, many people have influenced the development of new features in commercial EMG systems. However, within the last 3 decades, Erik Stålberg has always been in the forefront and has shown ways of implementing new methods for analyzing EMG activity or nerve signals. The development of new commercial EMG systems has been dependent on the technology introduced to the market at that particular period of time. This article only refers to systems that have been sold or are now being sold worldwide.

    2010-01-01

    The 1983 National Academy of Sciences report entitled "Changing Climate," authored by a committee of physical and social scientists chaired by William Nierenberg, was an early comprehensive review of the effects of human-caused increases in the levels of atmospheric CO2. Study of the events surrounding the committee's creation, deliberations, and subsequent report demonstrates that the conclusions of the report were the consensus of the entire committee and in line with the scientific consensus of the time. This result contraverts a 2008 paper in which Naomi Oreskes, Erik M. Conway, and Matthew Shindell asserted that the report contradicted a growing consensus about climate change, and that Nierenberg for political reasons deliberately altered the summary and conclusions of the report in a way that played down the concerns of the other physical scientists on the committee. Examining the production of the report and contextualizing it in contemporaneous scientific and political discussion, we instead show how it was a multi-year effort with work divided among the various members of the committee according to their expertise. The synthesis and conclusions were expressly a joint statement of the committee and were consistent with other assessments of that time expressing deep concern over the potential issues while stopping short of recommending major policy changes due to the uncertainties, and to a lack of good alternatives.

All panelists and the audience were asked to address the following questions • Current state-of-the-art efficiency of combined-cycle energy conversion technology is about 60%. Based on the trend of historical data, some forecast that second-law efficiency of energy conversion will reach 80% by the end of the century. What technologies are at sight that might hold this promise? • Nanotechnologies and microtechnologies point towards the development of microscopic heat engines? How do second law limitations map down to these scales? • Combustion is the principal way of converting the chemical energy of fossil fuels to thermal energy, but it is highly irreversible. Are there promising ways to reduce combustion irreversibility? Are fuel cells the only alternative to combustion?

    A fascinating chain of events led in 1941 to the formation of the Department of Physiology at the Royal Gymnastic Central Institute (GCI) in Stockholm, Sweden. Erik Hohwü Christensen, from the scientifically advanced Lindhard School in Copenhagen became its first professor. A central research question for him concerned determining the limiting factors for maximal physical performance in man. This was the academic setting where the sports interested medical student Bengt Saltin was introduced to exercise physiology. In the summer of 1959, he became involved in a study on intermittent vs continuous running. A doctoral project, with Per-Olof Åstrand as his tutor, resulted in 1964 as the thesis "Aerobic work capacity and circulation at exercise in man. With special reference to the effect of prolonged exercise and/or heat exposure". In the decade that followed, Saltin continued along that path. However, he also added a vital research line involving pioneering studies on skeletal muscles in the exercising man, a series of novel studies on the physiological demands in various sports, and studies of the effects of physical training within the general population.

  19. Lost Mountain: a year in the vanishing wilderness; radical strip mining and the devastation of Appalachia

    The mountains of Appalachia are home to one of the great forests of the world - they predate the Ice Age and scientists refer to them as the 'rainforests' of North America for their remarkable density and species diversity. These mountains also hold the mother lode of American coal, and the coal mining industry has long been the economic backbone for families in a region hard-pressed for other job opportunities. But recently, a new type of mining has been introduced -'radical strip mining', aka 'mountaintop removal'- in which a team employing no more than ten men and some heavy machinery literally blast off the top of a mountain, dump it in the valley below, and scoop out the coal. Erik Reece chronicles the year he spent witnessing the systematic decimation of a single mountain, aptly named 'Lost Mountain'. A native Kentuckian and the son of a coal worker, Reece makes it clear that strip mining is neither a local concern nor a radical contention, but a mainstream crisis that encompasses every hot-button issue - from corporate hubris and government neglect, to class conflict and poisoned groundwater, to irrevocable species extinction and landscape destruction. Published excerpts of Lost Mountain are already driving headlines and legislative action in Kentucky.

  20. Erikson's concept of ego identity reconsidered.

    PubMed

    Wallerstein, R S

    1998-01-01

    This paper explores and attempts to explain the paradox that Erik Erikson--after Freud, undoubtedly the psychoanalyst best known, most deeply esteemed, and most widely influential in the sociohistorical surround of world culture--has at the same time never been properly integrated into the psychoanalytic mainstream, but has instead been marginalized, consigned to a persisting psychoanalytic limbo. Two successive contexts within the historical unfolding of psychoanalysis in America, the milieu in which Erikson worked, would seem to account for this neglect. First, Erikson's monumental contributions to our understanding of the psychosocial developmental process, of the epigenesis of the ego, of the phase-specific developmental tasks across the eight postulated stages of the life cycle, and of the intergenerational cogwheeling of the life cycles were made during the 1950s and 1960s and could not easily be integrated into the ego psychology metapsychological paradigm then monolithically regnant within American psychoanalysis. And, second, as a major paradigm shift took place in America, beginning in the 1970s, toward a more relational, interpersonal, and intersubjective framework, Erikson's contributions, couched as they were in the structural language of the ego psychology of his time, were overlooked and went unremarked as seminal precursors of the newly emerging emphases. The clear relationship of Erikson's concepts of (ego) identity to emerging conceptions of self in relation to objects was simply not noticed, and his work continues to this day to be neglected and unintegrated within psychoanalysis.

    The life course has become a topic of growing interest within the social sciences. Attempts to link this sub-discipline with life span developmental psychology have been called for but with little sign of success. In this paper, we seek to address three interlinked issues concerning the potential for a more productive interchange between life course sociology and life span psychology. The first is to try to account for the failure of these two sub-disciplines to achieve any deepening engagement with each other, despite the long-expressed desirability of that goal; the second is to draw attention to the scope for enriching the sociology of the life course through Erik Erikson’s model of life span development; and the last is the potential for linking Eriksonian theory with current debates within mainstream sociology about the processes involved in ‘individualisation’ and ‘self-reflexivity’ as an alternative entry point to bring together these two fields of work.

    Objective: According to Erik Erikson, the main task of adolescents is to solve the crisis of identity versus role confusion. Research has shown that a stable and strong sense of identity is associated with better mental health of adolescents. Good relationships with peers are also linked with better emotional and psychological well-being of adolescents. However, there is a lack of reviews of studies in the scientific literature examining the relationship between the adolescents’ identity development and relationships with peers. The aims of this article were to analyze links between adolescent identity development and relationships with peers identified from a literature review, summarize the results, and discuss the theoretical factors that may predict these relationships. Method: A systematic literature review. Results: Analysis of findings from the systematic literature review revealed that a good relationship with peers is positively related to adolescent identity development, but empirical research in this area is extremely limited. Conclusions: The links between adolescents’ identity development and their relationship with peers are not completely clear. The possible intermediate factors that could determine the relationship between adolescent identity development and their relationships with peers are discussed. Further empirical researches is needed in this area. PMID:27274745

  3. Symbolic loss in American adolescents: mourning in teenage cinema.

    2014-04-01

    I argue that the changing economic conditions in the contemporary world have caused a shift in religious and cultural values among American youth. This shift in cultural and religious values and practices is interpreted in this essay as an experience of symbolic loss, or a loss of socially shared historic ideals and symbols (Homans in Childhood and selfhood: essays on tradition, religion, and modernity in the psychology of Erik H. Erikson. Bucknell University Press, Lewisburg, pp 189-228, 2008). I argue that the symbolic loss among American youth can most clearly be seen in the contemporary horror film genre in America. I assess the popularity of this genre, its value structure and the psychosocial consequences of the symbolic losses experienced by American youth as witnessed in this film genre. I suggest two ways in which adolescents and adults can work to re-create cultural and religious meanings that both foster courage and serenity in the face of the profound despair that accompanies the rage and paranoia in the contemporary horror film genre.

    The author argues that the paucity of options for sanctioned rebellion in contemporary American society drive an ever-increasing number of idealistic youth in search of isolation in nature, where they construct what the author here calls "nature religions." These worldviews focus on purification of falsehood, ritualized through enduring extreme physical pain, social isolation, and extreme weather conditions in hopes of experiencing reality more authentically. The author argues that unemployment, limited vocational options, and the homogenization of American society are among the major catalysts for this ever-expanding breed of seekers, each of whom struggles with a negative tendency (a theoretical term created by Erik Erikson). Furthermore, the author argues that the emphasis in the nature religions on connection to nature is constructed to compensate for the lack of community and sense of human connectedness in contemporary American society. A representative case study from Jon Krakauer's (Into the wild; Doubleday, New York, 1996) Into the Wild is presented to illuminate and justify the argument made by the author for more institutionally housed options for sanctioned, licit rebellion to manage the negative tendency.

  5. A four-fold humanity: Margaret Mead and psychological types.

    PubMed

    Beginning in 1933, while working in New Guinea, Margaret Mead developed her so-called squares hypothesis. Mead never published its terms, though she made a brief comment on it in her autobiography, Blackberry Winter (1972), and the arguments found in Sex and Temperament in Three Primitive Societies (1935) and the research leading to Balinese Character (Bateson & Mead, 1942) bore its imprint. Beginning with William McDougall's distinction between temperament (innate predispositions) and character (learned organization of habit), Mead articulated a morphological approach to the interplay between biology and culture that yielded four primary and four intermediary personality types. Under specified but not inevitable circumstances, the conscious choices of a given people could render one or another of these types characteristic or predominantly stable within their population, giving each of the other types a definite relation to the dominant type and thereby the cultural ethos of its society. Persons of each type followed a developmental path specific to their type different both from that of other types and in its manifestations given the various relations of the individual's type to the dominant type. Mead's hypothesis was, therefore, a vision of the unity and diversity of a single human species as well as an approach to the differing psychological positioning of individuals in cultures. In examining Mead's hypothesis, this essay also takes up Mead's debts to several leading psychologists (McDougall, C. G. Jung, and Erik Erikson), and (provisionally) how her vision differed from that of Ruth Benedict.

    Mechanics for the nonmathematician-a modern approach For physicists, mechanics is quite obviously geometric, yet the classical approach typically emphasizes abstract, mathematical formalism. Setting out to make mechanics both accessible and interesting for nonmathematicians, Richard Talman uses geometric methods to reveal qualitative aspects of the theory. He introduces concepts from differential geometry, differential forms, and tensor analysis, then applies them to areas of classical mechanics as well as other areas of physics, including optics, crystal diffraction, electromagnetism, relativity, and quantum mechanics. For easy reference, Dr. Talman treats separately Lagrangian, Hamiltonian, and Newtonian mechanics-exploring their geometric structure through vector fields, symplectic geometry, and gauge invariance respectively. Practical perturbative methods of approximation are also developed. Geometric Mechanics features illustrative examples and assumes only basic knowledge of Lagrangian mechanics.

    2005-03-01

    This paper explores the potential of Bourdieu's approach to capital as a way of understanding class dynamics in contemporary capitalism. Recent rethinking of class analysis has sought to move beyond what Rosemary Crompton (1998) calls the 'employment aggregate approach', one which involves categorizing people into class groups according to whether they have certain attributes (e.g. occupations). Instead, recent contributions by Pierre Bourdieu, Erik Wright, Aage Sorensen, and Charles Tilly have concentrated on understanding the mechanisms that produce class inequalities. Concepts such as assets, capitals and resources (CARs) are often used to explain how class inequalities are produced, but there remain ambiguities and differences in how such terms are understood. This paper identifies problems faced both by game theoretical Marxism and by the rational choice approach of Goldthorpe in developing an adequate approach to CARs. It then turns to critically consider how elements of Bourdieu's approach, where his concept of capital is related to those of habitus and field, might overcome these weaknesses. Our rendering of his arguments leads us to conclude that our understanding of CARs might be enriched by considering how capital is distinctive not in terms of distinct relations of exploitation, but through its potential to accumulate and to be converted to other resources. This focus, we suggest, sidesteps otherwise intractable problems in CAR based approaches.

    To facilitate the detection of quantitative trait loci (QTLs) for partial resistance to oat crown rust, Puccinia coronata f. sp. avenae Eriks., a genetic map was generated in a population of 158 F(6)-derived oat recombinant inbred lines from a cross of a partial resistance line MN841801-1 by a susceptible cultivar selection 'Noble-2'. The map, developed using 230 marker loci, mostly restriction fragment length polymorphism and amplified fragment length polymorphism markers, spanned 1,509 cM (Haldane) arranged into 30 linkage groups of 2-18 markers each. Four consistently detected major QTLs for partial rust resistance, Prq1a, Prq1b, Prq2, and Prq7, and three minor QTLs, Prq3, Prq5, and Prq6, were found in tests involving three field and two greenhouse environments. In addition, two major QTLs for flowering time, Ftq1 and Ftq7, and five weaker QTLs, Ftq2, Ftq3, Ftq4, Ftq5, and Ftq6, were revealed. Overlapping of the map segments of Ftq1 and Prq1 and of Ftq7 and Prq7 suggested either linkage between the flowering time QTLs and resistance QTLs or a pleiotropic effect of the Ftq QTLs on rust resistance. Relatively low heritability estimates (0.30) obtained for partial resistance to crown rust in the field indicate a potential value for marker-assisted selection.

    In 1857, Adold Erik Nordenskiöld (1832-1901), a Finnish geographer and mineralogist, was forced to withdraw from his position at the University of Helsinki because of a conflict with the czarist officials in Finland. He then moved to Sweden, where he became one of the most celebrated explorers of his time. Most famous of his polar expeditions was the discovery of the Northeast Passage. Nordenskiöld made his voyage in the wooden steamship Vega in 1878-79.Vega started its voyage on June 22, 1878, and was directed in a course around Scandinavia and along the Siberian coast toward Bering Strait. Nordenskiöld's plan was to reach the Pacific Ocean during the summer months, but this was hindered by unfavorable ice conditions. At the end of September the sea was blocked by ice fields, and the Vega had to pass the winter on the northern coast of the Chukchi Peninsula (67°4‧49″N, 173°23‧2″W)—exasperatingly close to the open waters of Bering Strait. The ship could not set sail any sooner than the following July when the sea was free again. After visiting Japan, China, and Ceylon, the Vega passed through the Suez Canal and finally, on April 24, 1880, arrived at Stockholm.

    Crown rust, caused by Puccinia coronata Corda f. sp. avenae Eriks., is a serious menace in oats, for which resistance is an effective means of control. Wild diploid oat accessions are a source of novel resistances that first need to be characterised prior to introgression into locally adapted oat cultivars. A genetic analysis of resistance to crown rust was carried out in three diverse diploid oat accessions (CIav6956, CIav9020, PI292226) and two cultivars (Saia and Glabrota) of A. strigosa. A single major gene conditioning resistance to Australian crown rust pathotype (Pt) 0000-2 was identified in each of the three accessions. Allelism tests suggested that these genes are either the same, allelic, or tightly linked with less than 1 % recombination. Similarly, a single gene was identified in Glabrota, and possibly two genes in Saia; both cultivars previously reported to carry two and three crown rust resistance genes, respectively. The identified seedling resistance genes could be deployed in combination with other resistance gene(s) to enhance durability of resistance to crown rust in hexaploid oat. Current diploid and hexaploid linkage maps and molecular anchor markers (simple sequence repeat [SSR] and diversity array technology [DArT] markers) should facilitate their mapping and introgression into hexaploid oat.

    The entropic gravity scenario recently proposed by Erik Verlinde reproduced Newton's law of purely classical gravity yet the key assumptions of this approach all have quantum mechanical origins. As is typical for emergent phenomena in physics, the underlying, more fundamental physics often reveals itself as corrections to the leading classical behavior. So one naturally wonders: where is ħ hiding in entropic gravity? To address this question, we first revisit the idea of holographic screen as well as entropy and its variation law in order to obtain a self-consistent approach to the problem. Next we argue that as the concept of minimal length has been invoked in the Bekenstein entropic derivation, the generalized uncertainty principle (GUP), which is a direct consequence of the minimal length, should be taken into consideration in the entropic interpretation of gravity. Indeed based on GUP it has been demonstrated that the black hole Bekenstein entropy area law must be modified not only in the strong but also in the weak gravity regime where in the weak gravity limit the GUP modified entropy exhibits a logarithmic correction. When applying it to the entropic interpretation, we demonstrate that the resulting gravity force law does include sub-leading order correction terms that depend on ħ. Such deviation from the classical Newton's law may serve as a probe to the validity of entropic gravity.

    Erik Noji, mentioned, tongue in cheek, Noah as the first disaster manager during a lecture in 2005. The canonical description of "The Genesis Flood" does describe Noah as a master planner and executer of an evacuation of biblical proportions. After gaining knowledge of a potential catastrophic disaster he planned and executed an evacuation to mitigate the effects of the "Genesis Flood" by building the Ark and organizing a mass exodus. He had to plan for food, water, shelter, medical care, waste disposal and other needs of all the evacuees. Throughout history, management of large disasters was conducted by the military. Indeed, the military still plays a large role in disaster response in many countries, particularly if the response is overseas and prolonged. The histories of emergency preparedness, disaster management and disaster medicine have coevolved and are inextricably intertwined. While disaster management in one form or another existed as long as people started living together in communities, the development of disaster medicine took off with the emergence of modern medicine. Similar to disaster management, disaster medicine also has roots in military organizations. PMID:27437524

    Despite having lost two of its reaction wheels, the Kepler mission has proven itself still capable of making discoveries. Now in a mission extension called K2, in which radiation pressure from the Sun stabilizes the spacecraft, Kepler has continued to detect planets in distant solar systems. And one of its latest discoveries is an especially intriguing pair of Earth-sized planets transiting a small, cool star only ~200 light-years away Transiting Discoveries: Earth-sized planets that orbit close to their host stars are thought to be remarkably common. Theyre predicted to exist around more than a quarter of Sun-like stars, and to be nearly ubiquitous around the smaller, cooler M dwarfs. Unfortunately, systems with M-dwarf hosts are hard to find, since theyre often very faint; a large survey is needed to spot the few M dwarfs near enough to be easily detectable. Luckily, Kepler has risen to the occasion Calibrated photometry for the K2-21 system, with the planet transits marked by red and teal ticks. Best-fit light curves for the transits are shown in the lower panels. Click for a closer look [Petigura et al. 2015] In a recent paper, a team of scientists led by Erik Petigura (Hubble Fellow at the California Institute of Technology) reports the discovery of two new transiting, Earth-sized planets around nearby M dwarf K2-21. The team followed up with spectroscopy of the host star, which allowed them to estimate that the two planets, K2-21b and K2-21c, have radii roughly 1.6 and 1.9 times the radius of Earth. These sizes mean that they straddle the boundary between high-density, rocky planets and low-density planets with thick gaseous envelopes.Unique PlanetsOne unanswered question about close-in, small planets common around dwarfs is whether they form in situ, or form far from their host and migrate inward. K2-21b and c have orbital periods of approximately 9.3 and 15.5 days, which means they are very nearly in a 5:3 resonance. This may be evidence that they formed

We examine this entanglement in the data collected from the three teachers. In the three teachers stories the proposed dimensions of experience shift in prominence. We focus on Erik's reflections on his teaching experience as well as his bodily gestures in teaching biological concepts and explanations to the pupils in a classical classroom setting. We discuss how Jane embodies and enacts her own childhood relations to nature and natural phenomena, recent in-service training, teaching experience and continued enthusiastic relation to nature and natural phenomenon. We also discuss how Tina exhibits a continued entanglement of past ethical experience and present embodiment of dedication to do good for others. By carefully attending to the entanglement of the three dimensions—continuity, relation and setting—, we hope to offer insight into the complex ways in which the body factors into science teaching practices.

    The wheat (Triticum aestivum L.) stem rust (Puccinia graminis Pers.:Pers. f.sp. tritici Eriks. and Henn.) resistance gene SrWld1 conditions resistance to all North American stem rust races and is an important gene in hard red spring (HRS) wheat cultivars. A sexually recombined race having virulence to SrWld1 was isolated in the 1980s. Our objective was to determine the genetics of resistance to the race. The recombinant race was tested with the set of stem rust differentials and with a set of 36 HRS and 6 durum cultivars. Chromosomal location studies in cultivars Len, Coteau, and Stoa were completed using aneuploid analysis, molecular markers, and allelism tests. Stem rust differential tests coded the race as TPPKC, indicating it differed from TPMKC by having added virulence on Sr30 as well as SrWld1. Genes effective against TPPKC were Sr6, Sr9a, Sr9b, Sr13, Sr24, Sr31, and Sr38. Genetic studies of resistance to TPPKC indicated that Len, Coteau, and Stoa likely carried Sr9b, that Coteau and Stoa carried Sr6, and Stoa carried Sr24. Tests of HRS and durum cultivars indicated that five HRS and one durum cultivar were susceptible to TPPKC. Susceptible HRS cultivars were postulated to have SrWld1 as their major stem rust resistance gene. Divide, the susceptible durum cultivar, was postulated to lack Sr13. We concluded that although TPPKC does not constitute a threat similar to TTKSK and its variants, some cultivars would be lost from production if TPPKC became established in the field.

    Employment relations, as a theoretical framework for social class, represent a complementary approach to social stratification. Employment relations introduce social relations of ownership and control over productive assets to the analysis of inequalities in economic (e.g., income), power (occupational hierarchy), and cultural (e.g., education) resources. The objectives of this paper are to briefly clarify the theoretical background on socio-economic indicators used in social epidemiology and to conduct a review of empirical studies that adopt relational social class indicators in the socio-epidemiological literature. Measures of employment relations in social determinants of health research can be classified within two major conceptual frameworks: 1) "Neo-Weberian", like the National Statistics Socio-Economic Classification (NS-SEC) which is widely used in the United Kingdom; and 2) "Neo-Marxian", like Erik O. Wright's social class indicators, which are being used by social epidemiologists in the Americas and Europe. Our review of empirical findings (49 articles found) reveals that the relation between employment relations and health does not necessarily imply a graded relationship. For example, small employers can exhibit worse health than highly skilled workers, and supervisors can display worse health than frontline workers. The policy implications of employment relations research are therefore different, and complement those of income or education health gradient studies. While the latter studies tend to emphasize income redistribution policy options, employment relations implicate other factors such as workplace democracy and social protection. Our analysis confirms that the current transformation of employment relations calls for new social class concepts and measures to explain social inequalities in health and to generate policies to reduce them.

    At the 7th Annual Congress of the European Association for Haemophilia and Allied Disorders (EAHAD) held in Brussels, Belgium, in February 2014, Pfizer sponsored a satellite symposium entitled: "Pharmacokinetics, phenotype and product choice in haemophilia B: How to strike a balance?" Co-chaired by Cedric Hermans (Cliniques Universitaires Saint Luc, Brussels, Belgium) and Mike Laffan (Imperial College, London, UK), the symposium provided an opportunity to debate whether pharmacokinetic (PK) parameters are good surrogates for clinical efficacy for haemophilia B in clinical practice, consider the perceptions and evidence of disease severity, and examine how these considerations can inform approaches to balancing the potential risks and benefits of the currently available treatment options for haemophilia B. PK parameters are routinely measured in clinical practice and are a requirement of regulatory bodies to demonstrate the clinical efficacy of products; however, the relationship between measured PK parameters and clinical efficacy is yet to be determined, an issue that was debated by Gerry Dolan (University Hospital, Queen's Medical Centre, Nottingham, UK) and Erik Berntorp (Lund University, Malmö Centre for Thrombosis and Haemostasis, Malmö, Sweden). Elena Santagostino (Universita degli Studi di Milano, Milano, Italy) reviewed how differing perceptions on the severity of haemophilia B compared with haemophilia A may have an impact on clinical decision-making. Finally, Andreas Tiede (Hannover Medical School, Hannover, Germany), examined the considerations for balancing the potential risks and benefits of the currently available treatment options for haemophilia B. Although the pathophysiology of haemophilia B has been widely studied and is largely understood, continued investigation and discussion around the optimal management course and appropriate therapeutic choice is warranted.

  6. Evaluating the Risks of High Altitude Travel in Chronic Liver Disease Patients.

    Luks, Andrew M., and Erik R. Swenson. Clinician's Corner: Evaluating the risks of high altitude travel in chronic liver disease patients. High Alt Med Biol 16:80-88, 2015.--With improvements in the quality of health care, people with chronic medical conditions are experiencing better quality of life and increasingly participating in a wider array of activities, including travel to high altitude. Whenever people with chronic diseases travel to this environment, it is important to consider whether the physiologic responses to hypobaric hypoxia will interact with the underlying medical condition such that the risk of acute altitude illness is increased or the medical condition itself may worsen. This review considers these questions as they pertain to patients with chronic liver disease. While the limited available evidence suggests there is no evidence of liver injury or dysfunction in normal individuals traveling as high as 5000 m, there is reason to suspect that two groups of cirrhosis patients are at increased risk for problems, hepatopulmonary syndrome patients, who are at risk for severe hypoxemia following ascent, and portopulmonary hypertension patients who may be at risk for high altitude pulmonary edema and acute right ventricular dysfunction. While liver transplant patients may tolerate high altitude exposure without difficulty, no information is available regarding the risks of long-term residence at altitude with chronic liver disease. All travelers with cirrhosis require careful pre-travel evaluation to identify conditions that might predispose to problems at altitude and develop risk mitigation strategies for these issues. Patients also require detailed counseling about recognition, prevention, and treatment of acute altitude illness and may require different medication regimens to prevent or treat altitude illness than used in healthy individuals.

  7. No room at the inn: a snapshot of an American emergency room.

    PubMed

    Olson, E J

    1994-01-01

    The emergency rooms of American hospitals have frequently become the principal suppliers of nonurgent primary care to the under- and uninsured. Canvassing published reports and using original data obtained from a representative urban hospital, Erik Olson examines the demographics of the American emergency room and analyzes its finances. The costs of providing primary care are shifted, to the extent possible, to those who can pay. The result is escalating health care costs and a deterioration of quality of care due to overcrowding, leading some hospitals to close their emergency rooms and others to turn away ambulances or "dump" patients who still require critical care. Mr. Olson explains that state antidumping laws and the federal COBRA statute have been ineffective at stemming these practices in the face of severe economic pressure to continue them. Pointing out that emergency rooms are an excessively expensive method of treating uninsured nonemergency patients, he proposes a system of primary care clinics created through a public/private partnership between municipalities and existing private health care providers. The partnership is designed to maintain a high standard of care at the clinics. As an incentive to stimulate the appearance of such clinics, a tax would be imposed on private health care providers; the tax on a given provider would be reduced to the extent that provider subsidizes a local primary care clinic that offers universal coverage, regardless of insurance status. Because the existence of such clinics would reduce inefficient use of hospital emergency rooms, in the long run hospitals should find it less expensive to finance local primary care clinics than to continue to sustain unreimbursed expenses due to improper use of their emergency departments.

    Short-range interatomic interactions govern many bio-molecular processes. Therefore, identifying close interaction partners in ensemble data is an essential task in structural biology and computational biophysics. A contact search can be cast as a typical range search problem for which efficient algorithms have been developed. However, none of those has yet been adapted to the context of macromolecular ensembles, particularly in a molecular dynamics (MD) framework. Here a set-decomposition algorithm is implemented which detects all contacting atoms or residues in maximum O(Nlog(N)) run-time, in contrast to the O(N2) complexity of a brute-force approach.

  9. Where are you sucking from? Using Stable Isotopes to understand Host Specificity in two Hemiparasitic plants above the tree line in Northern Sweden

    2012-12-01

    By Alejandro Macias, Erik Hobbie, Ruth Varner, Kaitlyn Steele Hemiparasites are known to suck nutrients from nearby plants but their host specificity is not well understood. Hemiparasites are ecosystem engineers, limiting surrounding plant's growth, and decreasing local biodiversity. To better understand this phenomenon, the host specificities of two hemiparasitic angiosperms, Bartsia alpina , and Pedicularis lapponica were studied above the tree line along an elevational gradient in Sweden. B. alpina specialized in wetter environments, as indicated by their higher δ13C signature, and their growth among Salixsp.Betula nana, Bistorta vivipara, Viola biflora, Geranium sp., and Trollious europaeus. P. lapponica was common in drier, less species rich environments, known as heaths, where B. nana, Empetrum negrum, Phyllodoce coeruela, Vaccinium myrtillus and Vaccinium vitis-idaea are the most common species. P. lapponica had higher foliage δ13C due to its better water-use efficiency in a dry environment. Field survey data and δN15 values of both the foliage of the parasitic plants and their potential hosts were used to determine host specificity. Since the δN15 value of the hemiparasitic plant and its host are similar due to parasitism, it was determined that P. lapponica had a preference for plants with an ericoid mycorrhizal association, such as Vaccinium sp, and E. negrum, but not for the common P. coeruela. This does not support the idea found in the literature that P. lapponica has a preference for grasses. B. alpina was less host specific, associating with non-mycorrhizal, ericoid, and ectomycorhizal plants, such as Carex sp, Vaccinium sp., and S. lapponum. The ectomycorrhizal species, Salix sp., and B. nana, were both potential hosts for B. alpina and P. lapponica due to their presence among them. However, the isotopic data revealed that B. alpina had a preference for Salix sp., and P. lapponica had a preference for B. nana.

    In the present structural concept, the Kocaeli Peninsula, as a part of the Istanbul Zone, was in Triassic times part of an Eurasian fragment on the northern edge of the northernmost Tethys branch. The Triassic sequence, exposed in the Kocaeli Peninsula (NW Turkey), represents well dated transgressive and regressive marine deposits. This "Kocaeli Triassic", being regarded as an important Triassic sequence has attracted the attention of a large number of scientists. The Kocaeli Triassic encompasses six formations: The red coloured Scythian Kapaklı Formation is barren and shows regressive features, resembling the underlying Permian facies; The Erikli Formation is the first marine deposition of Scythian age. The Late Scythian Demirciler Formation consists of micritic and dolomitic limestone. The unit shows bioturbation in the clayey limestone-limestone sequence. Covering a karstic surface, the Anisian Ballıkaya Formation consists of dolomite, dolomitic limestone and limestone, follow by the Tepeköy Formation that shows 4 different lithologies. At base, Anisian grey nodular and red nodular limestones equals the nodular limestones of the Kazmalı Formation laterally; The Late Anisian-Ladinian Ammonitico Rosso facies. The upper part consists of Carnian shale with Halobia and grey-green marls. Restricted to the Çerkeşli region, the Çerkeşli Formation consists of a pebbly limestones, as a lateral equivalent of the Tepeköy Formation. The Anisian platform conodonts include new taxa that are described. We also focus on several new ramiforms, adding to the multi-elemental and taxonomic diversities. The revised Anisian conodont biostratigraphy is presented. Key Words: Triassic, Anisian, Conodont, Kocaeli

  11. Herbert Olivecrona: founder of Swedish neurosurgery.

    PubMed

    Ljunggren, B

    1993-01-01

    Herbert Olivecrona (1891-1980) singlehandedly founded Swedish neurosurgery. At the International Congress in Neurology in Bern in August, 1931, Harvey Cushing invited the cream of the world's medical society to a private banquet. Among the 28 specially invited guests was Herbert Olivecrona. At 40 years old, Olivecrona took his seat with pioneers such as Otfrid Foerster, Percival Bailey, Hugh Cairns, Geoffrey Jefferson, and Sir Charles Sherrington. This suggests that Cushing was impressed by the Swedish aristocrat's didactic deeds when he visited the Serafimer Hospital in Stockholm 2 years earlier. During the mid-1920's, the radiologist Erik Lysholm greatly improved the technique of ventriculography and, challenged by Olivecrona, his diagnostic neuroradiology became of superior quality. In the early 1930's, utilizing technical innovations of his own, Lysholm became a master at demonstrating and localizing posterior fossa tumors, which Olivecrona then operated on. Olivecrona's clinic became the mecca to which many scholars, thirsting for more knowledge, went on a pilgrimage. The international reputation of the clinic was founded, not on epoch-making discoveries, but by the resolute and practical application of methods already launched elsewhere and the exemplary organization that Olivecrona had established in collaboration with Lysholm. In spite of hardships and primitive working conditions, the clinic at the Serafimer Hospital gradually developed into the ideal prototype for a modern neurosurgical department. Olivecrona trained many colorful personalities who later were to lay the foundation for neurosurgery in their home countries; these included Wilhelm Tönnis of Germany, Edvard Busch of Denmark, and Aarno Snellman of Finland. Olivecrona was a true pioneer who made major contributions in practically all fields of conventional neurosurgery.

    Stem rust, caused by Puccinia graminis Pers. f. sp. tritici Eriks. and E. Henn. (Pgt), is one of the most destructive diseases of wheat. Races of the pathogen in the "Ug99 lineage" are of international concern due to their virulence for widely used stem rust resistance genes and their spread throughout Africa. Disease resistant cultivars provide one of the best means for controlling stem rust. To identify quantitative trait loci (QTL) conferring resistance to African stem rust race TTKSK at the seedling stage, we evaluated an association mapping (AM) panel consisting of 230 tetraploid wheat accessions under greenhouse conditions. A high level of phenotypic variation was observed in response to race TTKSK in the AM panel, allowing for genome-wide association mapping of resistance QTL in wild, landrace, and cultivated tetraploid wheats. Thirty-five resistance QTL were identified on all chromosomes, and seventeen are of particular interest as identified by multiple associations. Many of the identified resistance loci were coincident with previously identified rust resistance genes; however, nine on chromosomes 1AL, 2AL, 4AL, 5BL, and 7BS may be novel. To validate AM results, a biparental population of 146 recombinant inbred lines was also considered, which derived from a cross between the resistant cultivar "Cirillo" and susceptible "Neodur." The stem rust resistance of Cirillo was conferred by a single gene on the distal region of chromosome arm 6AL in an interval map coincident with the resistance gene Sr13, and confirmed one of the resistance loci identified by AM. A search for candidate resistance genes was carried out in the regions where QTL were identified, and many of them corresponded to NBS-LRR genes and protein kinases with LRR domains. The results obtained in the present study are of great interest as a high level of genetic variability for resistance to race TTKSK was described in a germplasm panel comprising most of the tetraploid wheat sub-species.

    A live show on any subject that includes experiments and continuous interaction with the audience is a well known approach for EPO activities that many are carrying out all over. We present such an initiative with some added ingredients such as interdisciplinarity, the use of movie clips, and especially the debate between the two presenters, a debate that is all the more attractive to the public if it not fully staged but closely represents their actual points of view. José Montesinos, from the "Orotava" Canarian Foundation for the History of Science, is and plays the role of the more mature math professor who has grown weary of the overrated value given in science to mathematics and its consequences. This poses a constant challenge to his colleague, Erik Stengler, from the Science Museum of Tenerife, the young down-to-earth hands-on scientist, who defends the usual view that science and technology are to be judged by their achievements, which have brought about the advancement of modern society. With this approach and as a collaboration between our institutions, we have produced and toured highly successful activities on: Einstein and Relativity (from 2005 to 2008, "Einstein Goes To School," including a theatre play); circularity, the number π, forces of inertia and the Newtonian revolution (in 2008/2009, "The Tension Between Circularity and The Straight Line"); and the foundations of modern astronomy (in 2009/2010 "Kepler and Galileo, Messengers of the Stars"). Audiences were very varied - students, adult students, general public, prison inmates, teachers - and all appreciated the presentations as fun, thought-provoking and highly motivating, and valued especially the interdisciplinary character of the activity. Movie clips have shown to be especially useful to recover the attention of the young when they lose the thread due to the short attention spans they presently have.

    The CTBTO's International Data Centre is in the process of developing the next generation software to perform the automatic association step. The NetVISA software uses a Bayesian approach with a forward physical model using probabilistic representations of the propagation, station capabilities, background seismicity, noise detection statistics, and coda phase statistics. The software has been in development for a few years and is now reaching the stage where it is being tested in a realistic operational context. An interactive module has been developed where the NetVISA automatic events that are in addition to the Global Association (GA) results are presented to the analysts. We report on a series of tests where the results are examined and evaluated by seasoned analysts. Consistent with the statistics previously reported (Arora et al., 2013), the first test shows that the software is able to enhance analysis work by providing additional event hypothesis for consideration by analysts. A test on a three-day data set was performed and showed that the system found 42 additional real events out of 116 examined, including 6 that pass the criterion for the Reviewed Event Bulletin of the IDC. The software was functional in a realistic, real-time mode, during the occurrence of the fourth nuclear test claimed by the Democratic People's Republic of Korea on January 6th, 2016. Confirming a previous statistical observation, the software found more associated stations (51, including 35 primary stations) than GA (36, including 26 primary stations) for this event. Nimar S.

    Presents an obituary for Mollie Stevens Smart (1916-2012). Mollie attended the University of Toronto, from which she graduated with honors in psychology at age 20 in 1936. She studied and worked at the Merrill-Palmer Institute in Detroit, earning a master's degree in child development from the University of Michigan in 1941. She earned her doctorate in educational psychology at the University of Delhi in 1969. An author, teacher, and mentor, Mollie won Fulbright research grants to India and New Zealand and lectured in the United States, India, New Zealand, Canada, and China. She wrote 26 books, most co-authored with her husband, Russell (Rus) C. Smart. Beginning in the 1940s, when Freudian theory had a strong grip on the popular view of child development, the books placed the developing child in the context of family and community systems. The Smarts' best-selling college textbook Children: Development and Relationships (1967, 1973, 1977, 1982) was based on the theories of Erik Erikson and Jean Piaget. Mollie was a member of the American Psychological Association throughout her professional career and held memberships also in the Society for Research in Child Development, the National Council on Family Relations, the Groves Conference on Marriage and Family, and the Fulbright Association. After moving to Ridgefield, Washington, in 2003 with her daughter Ellen following Rus's death in 1996, she applied her great knowledge to advise a community-based organization that serves the needs of new babies born into destitute families. Mollie died at home in Ridgefield on October 22, 2012, at age 96.

  16. Child's play: the creativity of older adults.

    Capps, Donald

    2012-09-01

    In this article, I discuss Paul W. Pruyser's view presented in his article "An Essay on Creativity" (Pruyser in Bull Menninger Clin 43:294-353, 1979) that creative persons manifest early childhood qualities of playfulness, curiosity, and pleasure seeking and that adaptation is itself a form of creativity. I then discuss his article "Creativity in Aging Persons" (Pruyser in Bull Menninger Clin 51:425-435, 1987) in which he presents his view that aging itself is a potentially creative process, that creativity among older adults is not limited to the talented few, and that older adulthood has several specific features that are conducive to creativity. Significant among these features are object loss (especially involving human relationships) and functional loss (due to the vicissitudes of aging). Noting his particular emphasis on object loss and its role in late-life creativity, I focus on functional loss, and I emphasize the importance of adaptation in sustaining the creativity of older adults who experience such loss. I illustrate this adaptation by considering well-known painters who in late life suffered visual problems common to older adults. I suggest that in adapting to their visual problems these artists drew on the early childhood qualities (playfulness, curiosity and pleasure seeking) that all creative persons possess and that they are therefore illustrative for other older adults who are experiencing functional losses. I conclude with Erik H. Erikson's (Toys and reasons: stages in the ritualization of experience, W. W. Norton, New York, 1977) and Paul W. Pruyser's (Pastor Psychol 35:120-131, 1986) reflections on the relationship between seeing and hoping.

    After selecting five representative European psychoanalytic thinkers, all of whom emigrated to the United States, this essay surveys their earliest perceptions and interpretations of the historical and psychological roots of Fascism, with particular emphasis on anti-Semitism. My samples almost all derive from the period before, during, and immediately after World War II. In examining the writings of Otto Fenichel, Ernst Simmel, Erik Homburger Erikson, Rudolf Loewenstein and Bruno Bettelheim, it discusses the various environmental and psychological dimensions of their understandings of racial prejudice. The paper argues that each thinker attempted to integrate historical, sociological, cultural and clinical factors into their psychodynamic formulations about the individual and group mind of the Fascist anti-Semite. This generation of psychoanalysts explained Fascist anti-Semitism by exploring the mechanisms of projection, the process of massive splitting mechanisms of the group mind, fantasies of delinquent adolescent aggrandizement in Hitler, sado-masochistic and perverse oedipal dynamics, and a macabre identification with the torturers on the part of Jewish inmates in the concentration camps, that obliterated the individual's sense of autonomy and capacity to respond morally. The paper points out the pronounced ambivalence of this generation of Jewish analysts and intellectuals toward their own Jewish backgrounds and sense of themselves as Jews. It also argues that this generation muted its left-wing and socialist political tendencies once they arrived in America, taking a turn against politics. It suggests that some of the features of this Jewish ambivalence can be seen in the exploration of a so-called "Jewish psychology," itself a disguised form of racism, a derivative of projection, which may have had rather negative and authoritarian consequences for the psychoanalytic movement in America.

    1967-01-01

    Uredospores of Puccinia graminis (Pers.) tritici (Eriks. and Henn.) were uniformly labeled with 14C by permitting the host (Triticum aestivum L.) to carry out photosynthesis in 14CO2 during the process of spore production by the obligate parasite. The use of 14C labeled spores provided advantages in a study of the utilization of endogenous substrates at frequent intervals with small amounts of spores under conditions conducive to germination. Because of previous uncertainties about the nature of the substrates of importance to germination, a detailed study of carbohydrate and lipid components, both in the spores and in the germination medium, was made during the first 7 hours after placing the spores on aqueous media. Diethyl ether and 80% ethanol soluble metabolites each constituted approximately 20% of the total spore carbon. During the first hour nearly 60% of the 80% alcohol solubles disappeared from the spores while the total ether soluble material did not change appreciably. A significant part of the 80% ethanol soluble materials appeared in the germination medium. During germination and germ tube extension, there was rapid utilization of trehalose, arabitol and mannitol even though appreciable amounts of these materials were present as exogenous pools in the germination medium. Although the total amounts of ether soluble components did not change as drastically as the carbohydrate fraction, there was extensive utilization of palmitic, oleic, linolenic and 9,10-epoxyoctadecanoic acids. The results indicate that the germination process in spores of obligate parasites is not based solely on the utilization of lipids and some possible roles of the changes in internal and external pools of soluble carbohydrates are discussed.

Bengt was born in a rural village of Bjarnum in southern Sweden, located near forest and is known for its furniture making. He migrated to USA at the age of 35 and was recruited by Dr. Samuel Hellman to lead a group of physicists that became the “mecca of medical physics” known as the Joint Center of Radiation Therapy (JCRT) at Harvard Medical School in Boston. Bengt mentored some of the best physicists in the country, and many of our modern treatments go back to the early days of research at the JCRT. These accomplishments, dating from 1969–1989, include: dose optimization using computer control; soft wedges; stereotactic radiosurgery (SRS); total-body irradiation (TBI); CT-planning; and radiation dosimetry. Bengt worked at Brown University in Rhode Island and at the University of Pennsylvania in Philadelphia, where he provided major contributions in radiation dosimetry, specifically with the head scatter model. He advocated superior calculation algorithm through the Helax treatment planning system that was on par from most commercial systems. Bengt served as AAPM president in 1979 and was a recipient of the Coolidge Award in 1998. He had a lifelong love of nature, retiring in 2000 from the University of Pennsylvania to take care of his 200 acres of homestead forest in Maine. His legacy continues through his contributions to radiation dosimetry. This session, on small field dosimetry, is a small tribute to his memory.

    During the last years the use of paleoclimate simulations with models of different complexity has become an usual tool in paleoclimate studies. Progress in understanding climate variability leans on simulation and reconstruction efforts. Exercises blending both approaches present a great potential for answering questions relevant for both the simulation and reconstruction of past climate, and depend on the specific peculiarities of proxies and methods involved in climate reconstructions, as well as on the realism and limitations of model simulations. Most of paleoclimate integrations available in the literature covering the last millennium have been performed with relative rough resolution which does not allow to analyze regional climate features that can be of interest in the context of proxies evidence. In this work we present a new high resolution (30 km) regional climate simulation over the Iberian Peninsula of the last five. The regional simulations were performed with a climate version of the MM5 model coupled to the Noah LSM. The driving conditions used follow the Erik1 experiment, performed with the ECHO-G global circulation model. The results indicate that the seasonal modes of variation for near surface air temperature and precipitation obtained within the regional paleoclimate experiment are consistent with the obtained using the observational databases and equivalent to regional climate integrations driven by reanalysis data. On the other hand, the main modes of variation show strong signals in historical periods such as the Maunder and Dalton Minimum. Finally, some preliminary comparisons between the global and the regional model against reconstructions are also reported in this contribution.

  3. Polyimide Foams Offer Superior Insulation

    2012-01-01

    At Langley Research Center, Erik Weiser and his colleagues in the Advanced Materials and Processing Branch were working with a new substance for fabricating composites for use in supersonic aircraft. The team, however, was experiencing some frustration. Every time they tried to create a solid composite from the polyimide (an advanced polymer) material, it bubbled and foamed. It seemed like the team had reached a dead end in their research - until they had another idea. "We said, This isn t going to work for composites, but maybe we could make a foam out of it," Weiser says. "That was kind of our eureka moment, to see if we could go in a whole other direction. And it worked." Weiser and his colleagues invented a new kind of polyimide foam insulation they named TEEK. The innovation displayed a host of advantages over existing insulation options. Compared to other commercial foams, Weiser explains, polyimide foams perform well across a broad range of temperatures, noting that the NASA TEEK foams provide effective structural insulation up to 600 F and down to cryogenic temperatures. The foam does not burn or off-gas toxic fumes, and even at -423 F - the temperature of liquid hydrogen - the material stays flexible. The inventors could produce the TEEK foam at a range of densities, from 0.5 pounds per cubic foot up to 20 pounds per cubic foot, making the foam ideal for a range of applications, including as insulation for reusable launch vehicles and for cryogenic tanks and lines. They also developed a unique, friable balloon format for manufacturing the foam, producing it as hollow microspheres that allowed the foam to be molded and then cured into any desired shape - perfect for insulating pipes of different sizes and configurations. The team s originally unplanned invention won an "R&D 100" award, and a later form of the foam, called LaRC FPF-44 (Spinoff 2009), was named "NASA Invention of the Year" in 2007.

    Presents an obituary for Mollie Stevens Smart (1916-2012). Mollie attended the University of Toronto, from which she graduated with honors in psychology at age 20 in 1936. She studied and worked at the Merrill-Palmer Institute in Detroit, earning a master's degree in child development from the University of Michigan in 1941. She earned her doctorate in educational psychology at the University of Delhi in 1969. An author, teacher, and mentor, Mollie won Fulbright research grants to India and New Zealand and lectured in the United States, India, New Zealand, Canada, and China. She wrote 26 books, most co-authored with her husband, Russell (Rus) C. Smart. Beginning in the 1940s, when Freudian theory had a strong grip on the popular view of child development, the books placed the developing child in the context of family and community systems. The Smarts' best-selling college textbook Children: Development and Relationships (1967, 1973, 1977, 1982) was based on the theories of Erik Erikson and Jean Piaget. Mollie was a member of the American Psychological Association throughout her professional career and held memberships also in the Society for Research in Child Development, the National Council on Family Relations, the Groves Conference on Marriage and Family, and the Fulbright Association. After moving to Ridgefield, Washington, in 2003 with her daughter Ellen following Rus's death in 1996, she applied her great knowledge to advise a community-based organization that serves the needs of new babies born into destitute families. Mollie died at home in Ridgefield on October 22, 2012, at age 96. PMID:24016121

    As a SETI Institute PI from 1996-1998, Erik Asphaug studied impact and tidal physics and other geophysical processes associated with small (low-gravity) planetary bodies. This work included: a numerical impact simulation linking basaltic achondrite meteorites to asteroid 4 Vesta (Asphaug 1997), which laid the groundwork for an ongoing study of Martian meteorite ejection; cratering and catastrophic evolution of small bodies (with implications for their internal structure; Asphaug et al. 1996); genesis of grooved and degraded terrains in response to impact; maturation of regolith (Asphaug et al. 1997a); and the variation of crater outcome with impact angle, speed, and target structure. Research of impacts into porous, layered and prefractured targets (Asphaug et al. 1997b, 1998a) showed how shape, rheology and structure dramatically affects sizes and velocities of ejecta, and the survivability and impact-modification of comets and asteroids (Asphaug et al. 1998a). As an affiliate of the Galileo SSI Team, the PI studied problems related to cratering, tectonics, and regolith evolution, including an estimate of the impactor flux around Jupiter and the effect of impact on local and regional tectonics (Asphaug et al. 1998b). Other research included tidal breakup modeling (Asphaug and Benz 1996; Schenk et al. 1996), which is leading to a general understanding of the role of tides in planetesimal evolution. As a Guest Computational Investigator for NASA's BPCC/ESS supercomputer testbed, helped graft SPH3D onto an existing tree code tuned for the massively parallel Cray T3E (Olson and Asphaug, in preparation), obtaining a factor xIO00 speedup in code execution time (on 512 cpus). Runs which once took months are now completed in hours.

  6. Toward a molecular programming language for algorithmic self-assembly

    NASA Astrophysics Data System (ADS)

    Patitz, Matthew John

    Self-assembly is the process whereby relatively simple components autonomously combine to form more complex objects. Nature exhibits self-assembly to form everything from microscopic crystals to living cells to galaxies. With a desire to both form increasingly sophisticated products and to understand the basic components of living systems, scientists have developed and studied artificial self-assembling systems. One such framework is the Tile Assembly Model introduced by Erik Winfree in 1998. In this model, simple two-dimensional square 'tiles' are designed so that they self-assemble into desired shapes. The work in this thesis consists of a series of results which build toward the future goal of designing an abstracted, high-level programming language for designing the molecular components of self-assembling systems which can perform powerful computations and form into intricate structures. The first two sets of results demonstrate self-assembling systems which perform infinite series of computations that characterize computably enumerable and decidable languages, and exhibit tools for algorithmically generating the necessary sets of tiles. In the next chapter, methods for generating tile sets which self-assemble into complicated shapes, namely a class of discrete self-similar fractal structures, are presented. Next, a software package for graphically designing tile sets, simulating their self-assembly, and debugging designed systems is discussed. Finally, a high-level programming language which abstracts much of the complexity and tedium of designing such systems, while preventing many of the common errors, is presented. The summation of this body of work presents a broad coverage of the spectrum of desired outputs from artificial self-assembling systems and a progression in the sophistication of tools used to design them. By creating a broader and deeper set of modular tools for designing self-assembling systems, we hope to increase the complexity which is

    Stem rust (Puccinia graminis f. sp. tritici Eriks. & E. Henn.) (the causal agent of wheat stem rust) race Ug99 (also designated TTKSK) and its derivatives have defeated several important stem rust resistance genes widely used in wheat (Triticum aestivum L.) production, rendering much of the worldwide wheat acreage susceptible. In order to identify new resistance sources, a large collection of wheat relatives and genetic stocks maintained at the Wheat Genetic and Genomic Resources Center was screened. The results revealed that most accessions of the diploid relative Dasypyrum villosum (L.) Candargy were highly resistant. The screening of a set of wheat-D. villosum chromosome addition lines revealed that the wheat-D. villosum disomic addition line DA6V#3 was moderately resistant to race Ug99. The objective of the present study was to produce and characterize compensating wheat-D. villosum whole arm Robertsonian translocations (RobTs) involving chromosomes 6D of wheat and 6V#3 of D. villosum through the mechanism of centric breakage-fusion. Seven 6V#3-specific EST-STS markers were developed for screening F(2) progeny derived from plants double-monosomic for chromosomes 6D and 6V#3. Surprisingly, although 6D was the target chromosome, all recovered RobTs involved chromosome 6A implying a novel mechanism for the origin of RobTs. Homozygous translocations (T6AS·6V#3L and T6AL·6V#3S) with good plant vigor and full fertility were selected from F(3) families. A stem rust resistance gene was mapped to the long arm 6V#3L in T6AS·6V#3L and was designated as Sr52. Sr52 is temperature-sensitive and is most effective at 16°C, partially effective at 24°C, and ineffective at 28°C. The T6AS·6V#3L stock is a new source of resistance to Ug99, is cytogenetically stable, and may be useful in wheat improvement.

    July-to-October temperature variations are reconstructed for the last 800 years based on tree-ring widths from the Cazorla Range. Annual tree-ring width at this site has been found to be negatively correlated with temperature of the previous summer. This relationship is genuine, metabolically plausible, and cannot be explained as an indirect correlation mediated by hydroclimate. The resulting reconstruction (NCZ Tjaso ) represents the southernmost annually resolved temperature record based on tree-rings in Europe and provides detailed information on the regional climate evolution during the Late Holocene in the southeast of the Iberian Peninsula. The tree-ring based temperature reconstruction of Cazorla Range reveals predominantly warm summer temperatures during the transition between the Medieval Climate Anomaly (MCA) and the Little Ice Age (LIA) from the 13th to the mid of the sixteenth century. The LIA spanned a slightly longer time (1500-1930 CE) than in other European summer temperature reconstructions from the Alps and Pyrenees. The twentieth century, though warmer than the preceding centuries, does not show unprecedented warmth in the last 800 years. Three ensembles of climate simulations conducted with two global atmosphere-ocean general circulation climate models (GCMs), considering different external forcings, were used for comparison: ECHO-G (Erik) and MPI-ESM (E1 and E2). Additionally, individual simulations were available from GCM included in the fifth Coupled Model Intercomparison Project, as well as single-forcing simulations performed with MPI-ESM. The comparison of the reconstructed and simulated temperatures revealed a close agreement of NCZ Tjaso with the simulations performed with total solar irradiance forcing with wider amplitude. Furthermore, the correlations with single-forcing simulations suggest volcanism as the main factor controlling preindustrial summer temperature variations in the Cazorla Range over the last five centuries.

    2010-11-01

    This table shows coordinates and identifications for 1930 stars in northern Cygnus ('Northern Coalsack' region) classified by Erik Vanas in an early spectral survey. In the source paper, the stars were identified by BD number (part I of the catalogue) and by approximate coordinates for fainter non-BD stars (part II of the catalogue). The spectral types were determined from scans of objective-prism plates (~260Å/mm). Accurate coordinates of the BD stars were derived mainly from the Tycho-2 catalogue. The non-BD stars had to be identified one-by-one from DSS images via SkyView, usually unambiguous, and coordinates found in VizieR. For the non-BD stars, the acronym [V39] was used. For pairs or crowded stars, 2MASS positions are sometimes used. Where the type applies to a near-equal double star, the coordinates are for the mid-point between the two stars (rounded to 1" precision), and the magnitude is for the combined light. The original Vanas photo-blue magnitudes are somewhat uncertain, probably including a color term. Instead standard V magnitudes from Tycho-2 or from the TASS MkIV survey (Cat. II/271) are supplied. The Vanas spectral types are formally on the 'Uppsala' system, which includes the strength of the CN band to distinguish dwarfs and giants among types later than G5. These are shown in modern MK notation. The scheme also includes a pseudo-luminosity class for hot stars based largely on the width of the Balmer lines. Since the He lines were not involved in the classification, the system loses resolution (or 'granularity') for types earlier than A0. There is also the danger at this dispersion of mistaking a late-B supergiant for an early-B dwarf. From consideration of his descriptions of the spectra, and also comparison with types from modern sources for the same stars, these 'Greek-lettered' types were transformed in modern notation as: * types 'A0μ' given as A0V * types 'A0σ' and 'A0σ+' given as B8 * types 'B{tau}-' given as B, and are mainly B3 to B

    Wim J. de Lange, Geert F. Prinsen, Jacco H. Hoogewoud, Ab A Veldhuizen, Joachim Hunink, Erik F.W. Ruijgh, Timo Kroon Nationwide modeling aims to produce a balanced distribution of climate change effects (e.g. harm on crops) and possible compensation (e.g. volume fresh water) based on consistent calculation. The present work is based on the Netherlands Hydrological Instrument (NHI, www.nhi.nu), which is a national, integrated, hydrological model that simulates distribution, flow and storage of all water in the surface water and groundwater systems. The instrument is developed to assess the impact on water use on land-surface (sprinkling crops, drinking water) and in surface water (navigation, cooling). The regional expertise involved in the development of NHI come from all parties involved in the use, production and management of water, such as waterboards, drinking water supply companies, provinces, ngo's, and so on. Adequate prediction implies that the model computes changes in the order of magnitude that is relevant to the effects. In scenarios related to drought, adequate prediction applies to the water demand and the hydrological effects during average, dry, very dry and extremely dry periods. The NHI acts as a part of the so-called Deltamodel (www.deltamodel.nl), which aims to predict effects and compensating measures of climate change both on safety against flooding and on water shortage during drought. To assess the effects, a limited number of well-defined scenarios is used within the Deltamodel. The effects on demand of fresh water consist of an increase of the demand e.g. for surface water level control to prevent dike burst, for flushing salt in ditches, for sprinkling of crops, for preserving wet nature and so on. Many of the effects are dealt with by regional and local parties. Therefore, these parties have large interest in the outcome of the scenario analyses. They are participating in the assessment of the NHI previous to the start of the analyses

    Pervasive developmental disorders (PDD) are characterized by two essential symptoms: impairment in social interaction, and restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. PDD include autistic disorder, Asperger's disorder, and PDD-Not Otherwise Specified (PDD-NOS). These three disorders are sometimes termed autism spectrum disorders. A recent epidemiological survey demonstrated that the rate of PDD may be almost 1% and that many PDD cases might not be diagnosed properly in childhood. Erik Erikson described eight stages of psychosocial development through which a normally developing human should pass from infancy to adulthood. In the theory, an adolescent shows 'Identity vs. Role Confusion'. It has been reported that individuals with PDD often have identity crises which sometimes include gender dysphoria. This phenomenon might be related to the so-called identity diffusion in youth. When they reach their young youth, it has been said that subjects with PDD realize their uniqueness and differences compared to others, and, as a result, they may develop confusion of identity which could be exhibited as gender identity disorder. A recent study demonstrated that, amongst 204 children and adolescents who visited a GID clinic in the Netherlands, 7.8% were diagnosed with autism spectrum disorders after a careful diagnostic procedure by a multi-disciplinary team. Taken together, PDD and GID seem closely related to each other. In this paper, we present four PDD cases with gender dysphoria and related symptoms: 1) a girl with PDD who repeatedly asserted gender identity disorder (GID) symptoms in response to social isolation at school, 2) a junior high school boy with PDD and transvestism, 3) a boy diagnosed with Asperger's disorder who developed a disturbance of sexual orientation, and 4) a boy with Asperger's disorder and comorbid childhood GID. Many of the clinical symptoms related to gender dysphoria might be explained by the

    Primary socialization theory as formulated by Oetting and his associates emphasizes the transmission of societal norms during childhood and adolescence within society's three major socializing agencies: family, school, and small, intimate peer groups. The norms thus transmitted may be prosocial or deviant, with prosocial norms more likely to be transmitted through strong bonds to healthy families or schools. Personality traits and other personal characteristics influence negative outcomes, such as deviance or drug use, only to the extent that they interfere with socialization to family or school. Our own research does not address primary socialization theory directly in that we have not focused on the transmission of norms per se as central. Nevertheless, we have studied social factors, personality factors, and various psychopathologies as etiological for deviance and substance use. By and large our research has supported the hypotheses of primary socialization theory, even extending them in specific areas, such as the importance of family influences as etiological. Our work has also emphasized the significance of rebelliousness and impulse control in this regard. Like all large-scale theories which necessarily abstract from the totality and diversity of human behavior, primary socialization theory leaves some gaps requiring further elucidation. Among these is its ethnocentric and temporocentric perspective, but even within this perspective it understates the difficulties for adolescents in making a successful transition to adult social roles (Kingley Davis) and in establishing a unique identity independent of parents (Erik H. Erikson). Also, it generally ignores the salience of the youth culture as rebellious against the older generation, a particularly important characteristic of modern society. And finally, it should cover the process of "maturing out" of deviance, which perhaps results in a reaffirmation of the legitimacy of norms transmitted earlier, and it

    We request DDT time to observe transits of two super-Neptune planets orbiting a bright G star, EPIC 203371098. Erik Petigura has brought to our attention a particularly interesting K2 discovery that consists of two sub-Saturn-sized planets (5.9 RE and 7.8 RE) orbiting EPIC-203371098, a bright G star (K = 9.2). The orbital periods of the planets are 20.9 d and 42.4 d, respectively. The planets have sizes between that of Neptune and Saturn; sizes not represented among the Solar System planets. Due to the brightness of the host star, this system is an ideal laboratory to study this new class of planets. Over the past two months, our team has conducted radial velocity (RV) follow up of EPIC-203371098 with Keck/HIRES. Our preliminary measurements suggest these planets have low densities, ~0.6 g/cc and ~0.4 g/cc, respectively. Low planet masses translate into larger atmospheric scale heights, which sets the amplitude of the features in planet transmission spectra. The apparent commensurability of their orbits suggest that this is a resonant system where transit timing variations may be particularly large. Our Spitzer observations, compared with the previous K2 first epoch observations, can provide initial evidence for TTVs and set the stage for future campaigns from Spitzer and other telescopes which will independently determine the planetary masses; they will also pin down the ephemerides of these interesting planets - including the hard to capture orbital eccentricity - for possible JWST study.It is important to carry out these observations in the upcoming apparition of this star in the October-December time frame because multiple observations are required for accurate studies of TTVs, and to prevent secular errors in timing from building up to a point where the system is hard to recover. The size of these planets and the brightness of the star shows us that we will achieve S/N>20 per transit on each planet.We will propose to observe one transit of each planet

    Stem rust, caused by Puccinia graminis Pers. f. sp. tritici Eriks. and E. Henn. (Pgt), is one of the most destructive diseases of wheat. Races of the pathogen in the “Ug99 lineage” are of international concern due to their virulence for widely used stem rust resistance genes and their spread throughout Africa. Disease resistant cultivars provide one of the best means for controlling stem rust. To identify quantitative trait loci (QTL) conferring resistance to African stem rust race TTKSK at the seedling stage, we evaluated an association mapping (AM) panel consisting of 230 tetraploid wheat accessions under greenhouse conditions. A high level of phenotypic variation was observed in response to race TTKSK in the AM panel, allowing for genome-wide association mapping of resistance QTL in wild, landrace, and cultivated tetraploid wheats. Thirty-five resistance QTL were identified on all chromosomes, and seventeen are of particular interest as identified by multiple associations. Many of the identified resistance loci were coincident with previously identified rust resistance genes; however, nine on chromosomes 1AL, 2AL, 4AL, 5BL, and 7BS may be novel. To validate AM results, a biparental population of 146 recombinant inbred lines was also considered, which derived from a cross between the resistant cultivar “Cirillo” and susceptible “Neodur.” The stem rust resistance of Cirillo was conferred by a single gene on the distal region of chromosome arm 6AL in an interval map coincident with the resistance gene Sr13, and confirmed one of the resistance loci identified by AM. A search for candidate resistance genes was carried out in the regions where QTL were identified, and many of them corresponded to NBS-LRR genes and protein kinases with LRR domains. The results obtained in the present study are of great interest as a high level of genetic variability for resistance to race TTKSK was described in a germplasm panel comprising most of the tetraploid wheat sub

For the interpretation of the maps we used results, obtained during the work on Russian Federal Program "Integration" (grant #B-0038). The coordinates of plots of survey were measured with GPS, and magnetic maps included in GIS with help of MapInfo software. We would like to express our appreciation to Dr. Finn Erik Kramer (Sophienborg Nordsjællandsk Folkmuseum, Denmark) for perfect organisation of the survey and NORDEA Bank, Denmark sponsored the work.

    a limited area domain. These models are often used in climate change projections, as they have proven to be able to improve several aspects of the GCM simulations. An important caveat in the use of models to simulate the past climate is the fact that the model has its own internal variability. For this reason, the evolution of the simulated climate has an important charge of uncertainty. In particular, it is not easy to assess whether a simulated cold period is driven by variations in the external forcings (and thus it makes sense when compared with proxy reconstructions) or simply due to a natural fluctuation of the simulation. Regarding this issue, ensembles of simulations may help to assess the internal variability of models. However this kind of ensembles are rare nowadays due to the huge computational cost involved. In this study we present a comparison between two simulations of the past climate performed with a climate version of the regional model MM5. The model domain covers the Iberian Peninsula with a a spatial resolution of 30 km. Both RCM simulations are driven by paleo experiments, ERIK1 and ERIK2, performed with the GCM model ECHOG for the last millennium. Both simulations were forced by the same reconstructions of the evolution of solar power, big volcano events and evolution in the concentration of Greenhouse Gases. The only difference between the two simulations is therefore the initial condition in the GCM. This leads nevertheless to a different evolution of the simulated climate, due to the internal variability of the model. The results indicate that MM5 is capable of improving the reliability of the GCM simulations, in particular the mean values and the variability of precipitation and near-surface temperature. The intercomparison between the two simulations also depicts a number of cold and warm periods that are simultaneous in both experiments; these periods match with some well known cold periods, such as the Maunder Minimum.

    few minor light chemical elements, have all been created by the various generations of stars. [2] As every rainbow demonstrates, white light can be split up into different colours. Astronomers artificially split up the light they receive from distant objects into its different colours (or wavelengths). However, where we distinguish seven rainbow colours, astronomers map hundreds of finely nuanced colours, producing a spectrum - a record of the different amounts of light the object emits in each narrow colour band. The details of the spectrum - more light emitted at some colours, less light at others - provide tell-tale signs about the chemical composition of the matter producing the light. [3] The Dwarf galaxies Abundances and Radial-velocities Team (DART) has members from institutes in nine different countries. More information This research was presented in a paper to appear in Astronomy and Astrophysics ("The NIR Ca II triplet at low metallicity", E. Starkenburg et al.). Another paper is also in preparation (Tafelmeyer et al.) that presents the UVES measurements of several primitive stars. The team is composed of Else Starkenburg, Eline Tolstoy, Amina Helmi, and Thomas de Boer (Kapteyn Astronomical Institute, University of Groningen, the Netherlands), Vanessa Hill (Laboratoire Cassiopée, Université de Nice Sophia Antipolis, Observatoire de la Côte d'Azur, CNRS, France), Jonay I.

    Author: Ramona Bergman, Yvonne Andersson-Sköld, Lars Nyberg, Magnus Johansson, Erik Persson Preventive actions can be, and are frequently, taken to reduce accidents and their consequences in different ways. The MSB funded research programme "Effects of Society's Security actions" (ESS, 2009-2013) aims to study the relationship between such actions and their effects. The program is divided into three subgroups: Frequent accidents Natural hazards (such as flooding, erosion and landslide) Chemical and landfill accidents The results presented here covers natural hazards with focus on land slides and flooding. The results are based on Swedish/Scandinavian contexts. Natural events such as erosion, flooding and land slides are common, but the number of accidents (events causing severe negative impact) is rare. Therefore, in such analysis there is limited data and other information available which can be used for example in statistical analysis of actions and their effects. Instead, the analysis must be based on other information. Therefore, the analysis may have to include aspects that only can be assessed by scenario and "what-if" analyses. In this project the main method has been interviews with officials in Swedish municipalities and national agencies in Sweden and Norway. The two levels are chosen since policies are taken on national (or international) level, while the key actions and actors are on the municipal level. The interviews cover experiences and potential scenarios. In all municipalities, one politician and officials working with planning and rescue service have been interviewed. The study covers hazard and risk mapping, follow up of such maps, physical planning and lessons learned from previous events and activities. The final outcome of the research will be a review of what is found to be well functioning, identification of weak points and recommendations for the management of landslides, erosion and flooding. The present results indicate that hazard

    advantages of this technique are that no solvents, etchants or photoresist come into contact with the YBCO, hence this technique has a potential for operational-asgrown devices. In summary, it is now possible to produce YBCO films with structural and DC electrical properties which rival the most optimized c-axis epitaxial YBCO films on MgO, SrTiO3 and LaAlO3. Preliminary measurements of microwave properties appear promising.

  5. Rethinking Uncertainty: What Does the Public Need to Know?

    NASA Astrophysics Data System (ADS)

    Oreskes, N.

    2012-12-01

    The late Steven Schneider is often quoted as addressing the double-bind of science communication: that to be a good scientist one has to be cautious and acknowledge uncertainty, but to reach the media and the public one has to be bold, incautious, and even a bit dramatic. Here, I focus on a related but different double-bind: the double bind of responding to doubt. In our recent book, Merchants of Doubt, Erik M. Conway and I showed how doubt-mongers exploited scientific uncertainty as a political strategy to confuse the public and delay action on a range of environmental issues from the harms of tobacco to the reality of anthropogenic climate change. This strategy is effective because it appeals to lay people, journalists,' and even fellow scientists' sense of fair play—that it is right to hear "both sides" of an issue. Scientists are then caught in a double-bind: refusing to respond seems smug and elitist, but responding scientifically seems to confirm that there is in fact a scientific debate. Doubt-mongering is also hard to counter because our knowledge is, in fact, uncertain, so when we communicate in conventional scientific ways, acknowledging the uncertainties and limits in our understanding, we may end up reinforcing the uncertainty framework. The difficulty is exacerbated by the natural tendency of scientists to focus on novel and original results, rather than matters that are well established, lest we be accused of lacking originality or of taking credit for other's work. The net result is the impression among lay people that our knowledge is very likely to change and therefore a weak basis for making public policy decision. History of science, however, suggests a different picture: we know that a good deal of scientific knowledge has proved temporally robust and has provided a firm basis for effective public policy. Action on earlier environmental issues such as DDT and acid rain, guided by scientific knowledge, has worked to limit environmental damage

    particularly address the key issues associated with x-pinches, which include radiation transport, energetic particle transport, supersonic jet formation, using state-of-the-art compact pulsed power drivers. All the primary objectives of the proposed work were met. These objectives include: • Understanding of the fundamental physics of hot and dense plasma formation, implosion to less than 1 µm size due to the radiation enhanced collapse and energetic electron heating, • Study of the jet formation mechanism, which is of interest due to the astrophysical jets and deposition of energy by energetic electrons in jets, • Characterization of an x-pinch as a point x-ray source for the phase contrast radiography of beryllium cryogenic targets for the National Ignition Facility (NIF) experiments. The work carried out included a strong educational component involving both undergraduate and graduate students. Several undergraduate students from University of California San Diego participated in this project. A post-doctoral fellow, Dr. Simon Bott and two graduate students, David Haas and Erik Shipton contributed to every aspect of this project. The success of the project can be judged from the fact that fifteen peer-reviewed papers were published in high quality journals. In addition several presentations were made to a number of scientific meetings.

    Two science teachers accompanied an international scientific party of the Integrated Ocean Drilling Program on a 6-week expedition to the high Arctic Ocean this summer. Kathy Couchon, a middle school science teacher from Narragansett, RI, was sponsored by the NSF-funded ARMADA Project (www.armadaproject.org), directed by the Office of Marine Programs at the University of Rhode Island. Erik Zetterberg, a high school teacher from Sweden, was sponsored by the Swedish Polar Research Secretariat. The purpose of the expedition was to collect rock and sediment cores in order to reconstruct environmental and climatic conditions in the polar region over the past 60 million years. The $12.5M expedition involved over 200 people from more than 10 countries, three icebreakers, and two helicopters. Cores collected on one vessel were transferred to a laboratory on another, where 20 scientists analyzed microfossils as well as sedimentology, chemistry, and lithology. The teachers participated early in all aspects of the expedition, including coring operations, helicopter flights for ice reconnaissance, laboratory work, and science meetings. Formal education, such as learning how to prepare sediment samples for micropaleontological analysis, was complemented by informal education during one-on-one conversations with scientists over meals, or in social gatherings. The teachers posted reports regularly on websites (e.g., http://tea.rice.edu tea_cuchonfrontpage.html) and participated in a teleconference via Iridium satellite phone. When asked to compare preconceived notions with actual experience, the teachers noted the following: (1) there are many things that scientists don't know (and they are often the first to admit this); (2) the excitement of scientific exploration and discovery does not diminish with age and experience; (3) teamwork among the scientists was greater than expected, and competition among individuals was not observed; and (4) much in the natural world is unknown

    an important example. Understanding surface solar 'dimming' and 'brightening' trends in the context of past and current changes in the water cycle are discussed in a guest editorial by Wild and Liepert (2010). The key roles anthropogenic aerosols can play on a regional scale are discussed by Lau et al (2010) through their study of the regional impact of absorbing aerosols on warming and snow melt over the Himalayas. The overarching goal of climate prediction is to provide reliable, probabilistic estimates of future changes. Relating hydrological responses back to a sound physical basis, the motivation for this special focus issue, is paramount in building confidence in anticipated changes, especially in the global water cycle. We are grateful to the reviewers and the journal editorial board for making this focus issue possible.

    % followed by concrete dust, plastic crumbs, other man made materials, clay and other minerals. The major part of the mineralogical composition was dominated by Montmorillonite and Kaolinite as is it expected to be in the Mount Carmel soils. Pyroxene and Olivine are also typical to the mineralogy of the Mount Carmel were there are several known magmatic eruption areas of Scoria and Basalt. There is a high frequency of Actinolite (Ca2(Mg,Fe)5(Si8O22)(OH)2), Amphibole family (2.5%) that is typical to metamorphic rocks that are not to be found in the Mount Carmel region. Some of the mineral found in the analysis is of marine origin like Syngenite (K2Ca(SO4)2(H2O)) and Blodite (Na2Mg(SO4)24(H2O)) as the area was created under the Mediterranean Sea and is still influence by it. None of the endmembers were detected only once, the lowest frequency was 4 times for Cyanide-Cadmium (Cd(CN)2) and Andalusite (Al2SiO5). The results of the soils pH, measured electrometrically and the particle size distribution, measured by Laser diffraction, indicate there is no big different between the samples particle size distribution and the pH values of the samples but they are not significantly different from the expected, except for the OM percentage which is significantly higher in most samples. The suggested method was very effective for tracing the man-made substances, we could find concrete and asphalt, plastic and synthetic polymers after they were assimilated, broken down and decomposed into soil particles. By the top-down unmixing method we did not limit the substances we characterize and so we could detect unexpected materials and contaminants. Gómez-Baggethun, Erik and David N. Barton. 2013.

    , together comprising about 100 scientists from universities and scientific institutes, and led by Professor Erik Hoeg (Copenhagen University Observatory, Denmark), Professor Jean Kovalevsky (Observatoire de la C.te d'Azur, France), Dr. Lennart Lindegren (Lund Observatory, Sweden) and Dr. Catherine Turon (Observatoire de Meudon, France). Final accuracies on the stellar positions, distances and annual motions measured by Hipparcos, are in the range 1-2 milli-arcsec (i.e. 1-2 thousandths of a second of arc, equivalent to the angular size of a golf ball viewed from the other side of the Atlantic Ocean). Distances of stars many millions of times further away than our own Sun are being measured, and their velocities are being measured with accuracies of a few hundred metres per second. A further million stars will be contained in the accompanying Tycho Catalogue, with positions not as accurate as those derived from the main experiment, although still considerably more accurate than those measurable from the ground. At the heart of the satellite was an extremely accurate optical telescope, which measured the separations between stars in different parts of the sky as the satellite turned slowly around its axis. The telescope mirrors on Hipparcos were so accurately polished that, if scaled up to the size of the Atlantic Ocean, deviations of the surface would nowhere exceed 10 cm in height. The global positional accuracies determined by Hipparcos are impossible to achieve from the Earth's surface, where the atmosphere, the temperature variations, instrument flexure, and the absence of all- sky visibility provide insurmountable barriers to ground-based observers. The Hipparcos results will represent a milestone in mankind's understanding of the structure and evolution of our Galaxy, and an invaluable legacy to future generations of astronomers.

    been removed here. These observations provide the long-sought missing pieces of the puzzle to get a clear overview of the solar neighbourhood. They effectively mark the conclusion of a project started more than twenty years ago.. In fact, this work marks the fulfilment of an old dream by Danish astronomer Bengt Strömgren (1908-1987), who pioneered the study of the history of the Milky Way through systematic studies of its stars. Already in the 1950's he designed a special system of colour measurements to determine the chemical composition and ages of many stars very efficiently. And the Danish 50-cm and 1.5-m telescopes at the ESO La Silla Observatory (Chile) were constructed to make such projects possible. Another Danish astronomer, Erik Heyn Olsen made the first step in the 1980's by measuring the flux (light intensity) in several wavebands (in the "Strömgren photometric system") of 30,000 A, F and G stars over the whole sky to a fixed brightness limit. Next, ESA's Hipparcos satellite determined precise distances and velocities in the plane of the sky for these and many other stars. The missing link was the motions along the line of sight (the so-called radial velocities). They were then measured by the present team from the Doppler shift of spectral lines of the stars (the same technique that is used to detect planets around other stars), using the specialized CORAVEL instrument.

    the Tycho results on a million stars with positions of the same stars observed from the ground during the past 100 years, to measure their motions across the sky. The Danish astronomer Erik Hog is a worthy heir of Tycho Brahe. He adopted a star mapper, installed in Hipparcos for checking the telescope's aim, as an additional source of astrometric data. From Copenhagen University Observatory he led the multinational Tycho Data Analysis Consortium (TDAC) which produced the Tycho Catalogue. "A million million bits of data came from our star mapper in Hipparcos," Hog remarks. "We nearly drowned in the torrent when we started. So we limited the Tycho Catalogue to one million stars, in order to keep up with the work on the Hipparcos Catalogue. With more experience and faster computers, and based on the Hipparcos and Tycho Catalogues, we've started work on a Second Tycho Catalogue of three million stars. We hope to have it ready by 1999."

    institute directed by Professor Wolfgang Ernst. The story of how this particular collaboration developed is interesting because it illustrates again how important personal contacts and social interactions are in the progress of science. In 2007 I was contacted by Bodil Holst, then of the TU-Graz and now at the Technical University of Bergen in Norway, about the possibility of having one of her very bright graduate students visit Clemson for a few months as a part of his work in analyzing some He atom scattering data that they had taken on silica glass surfaces. A decade earlier Holst had been a postdoctoral research associate at the Toennies laboratory in Göttingen during several of the summers I was also there and, although we never worked directly together at that time, we had many interesting discussions about science and other subjects. The student, Wolfram Steurer, arrived in Clemson in the middle of the fall semester with his belongings in a bag that was smaller than the guitar he carried strapped over his back. He immediately created for himself a place in our department, and by the time he left three months later we had developed some rudimentary ideas of how to analyze the data he had, and we also suspected that this data might reveal some new aspects of the dynamics of glass surfaces that had not been realized before. Wolfram delved into this problem with a vengeance, and shortly afterwards we began a series of papers involving Holst, Ernst and Steurer and the Graz graduate students, Andreas Apfolter and Mattias Koch, as well as Elin Søndergård of the French CNRS laboratory located at the St Gobain Corporation's research facilities in Paris. It was this initial contact with Holst a decade earlier that eventually led to a productive period of research on glass surfaces, something that I would have never predicted beforehand, but a collaboration that shows every sign of continuing into the future to produce new and interesting results. So, this brings the history

    perspective, when the results are delivered to them at the end of March 1996. The final product of the Hipparcos mission, a monumental 14-volume catalogue, with page upon page of astronomical results of unprecedented accuracy, will be published by ESA and the scientific teams at the end of March 1997. The four leaders of he European scientific teams, who have been involved in the project since its earliest days, announced hat he Hipparcos and Tycho Catalogues have passed all he test that they have been able to devise to assess he quality of he data. Professor Jean Kovalevsky (Observatoire de la Cote d'Azur, Grasse, France), Dr Lennart Lindegren (Lund Observatory, Sweden), Professor Erik Hog (Copenhagen Observatory, Denmark), and Dr Catherine Turon (Observatoire de Paris-Meudon), and other scientific representatives from the ESA member states, are delighted with he latest developments. "There will be thousands of direct and indirect users of the Hipparcos results over the coming years", said Catherine Turon who lead the team responsible for putting together the satellite's observing programme, "and they will not only have access to a magnificent catalogue, but one which has been finalised somewhat more rapidly than our expectations before launch ". Some ten thousand known double star systems have been observed by Hipparcos, and nearly ten thousand more have been discovered for the first time. In these binary systems, two stars orbit around each other, and Hipparcos promises to provide measurements of the masses of he stars in such systems, information which is impossible to determine in any other way. "Many of our scientific colleagues who have waited patiently for the results of this mission will be astonished with what the final catalogue contains" said Professor Hog, originator of he Tycho Catalogue concept, and one of the hiving forces behind the mission. In thousands of cases, the stars are seen to be variable by Hipparcos. In these cases, the light output from he star

    )This afternoon breakout session included a drinking-from-the-firehose set of short talks that covered everything from source-code management and software testing to building communities that create sustainable code. First, Kenza Arraki discussed software such as Git to do version control to keep track of code changes. (Version Control is my (science) New Years Resolution, so I was happy to learn that there is aCodeAcademy tutorial for Git!). Next up, AdrianPrice-Whelan described the merits of software testing and suggests that we actually do Test-driven development where we write tests for the code first, then write code, run tests and debug until tests all pass. Erik Tollerud spoke on Why Document code and how you might convince yourself to do so (documenting code is another good science New Years Resolution!) The most important rule is to always document as you code because you wont ever go back! Bruce Berriman described the best practices for code release, including, importantly, licensing it and describing it well (with tutorials, examples). Matthew Turk reminded us the importance of building community around code development. Robert Nemiroff ended the talks with a discussion of what to do withdeadcodes. The lowest bar? Put it in your Dropbox and share it with your collaborators and students!For more info on all of these topics and more, consider attending a Software Carpentry workshop.

    formation rate at this early stage of the evolution of the galaxy. Notes [1] 1 billion = 1,000 million. [2] These figures indicate the percentage of the photons from a celestial object entering the UVES spectrograph slit that are effectively registered by the detectors. For comparison, astronomical spectrographs constructed in the early 1990's only reached efficiencies of the order of 5% and 10% in these wavebands, respectively. The very effective performance of UVES thus signifies another important gain (in addition to that caused by the large mirror of KUEYEN), allowing comparatively fainter objects to be observed, or shorter integration times in the case of brighter objects. [3] The "spectral resolution" indicates the amount of spectral detail that is registered. The number is calculated as the wavelength of observation, divided by the smallest wavelength difference at which two spectral lines can still be resolved. A resolution of 115,000 at the wavelength of H-alpha, a prominent hydrogen emission line at 656.2 nm in the red spectral region, thus corresponds to the possibility of recording individual spectral features that are only 0.006 nm apart (or a velocity difference of about 0.26 km/sec). [4] The UVES Instrument Science Team was constituted at the end of 1992 and is composed by Bengt Gustafsson (Uppsala Observatory, Sweden), Herman Hensberge (Royal Observatory, Bruxelles, Belgium), Paolo Molaro (Trieste Astronomical Observatory, Italy) and Poul Erik Nissen (Chairman, Aarhus University, Denmark). The team members followed the development of the instrument from the early design phase to its installation at Paranal, providing timely advice on all science-related matters. Antoinette Songaila (Hawaii, USA) and Francesco Bertola (Padova, Italy) also contributed to the first evaluation of the data. A.
