Sample records for millennium personality structure

  1. Using the Millennium II simulation to test CDM predictions for the structure of massive galaxies

    NASA Astrophysics Data System (ADS)

    Cooper, Andrew P.; Kauffmann, Guinevere; Wang, Jing; White, Simon D. M.

    2013-07-01

    We have combined the semi-analytic galaxy formation model of Guo et al. (2011) with a novel particle-tagging technique to predict galaxy surface brightness profiles in a representative sample of ~1900 massive dark matter haloes (1012-1014 M⊙) from the Millennium II ΛCDM N body simulation. We focus on the outer regions of galaxies and stars accreted in mergers. Our simulations cover scales from the stellar haloes of Milky Way-like galaxies to the `cD envelopes' of groups and clusters, and resolve low surface brightness substructure such as the tidal streams of dwarf galaxies. We find that the spatial distribution of stars in low surface brightness regions is tightly correlated with DM halo mass and that collisionless merging during the hierarchical assembly of galaxies largely determines the structure of spheroidal stellar components. Our ΛCDM model agrees well with the available data.

    STING Millennium Suite (SMS) is a new web-based suite of programs and databases providing visualization and a complex analysis of molecular sequence and structure for the data deposited at the Protein Data Bank (PDB). SMS operates with a collection of both publicly available data (PDB, HSSP, Prosite) and its own data (contacts, interface contacts, surface accessibility). Biologists find SMS useful because it provides a variety of algorithms and validated data, wrapped-up in a user friendly web interface. Using SMS it is now possible to analyze sequence to structure relationships, the quality of the structure, nature and volume of atomic contacts of intra and inter chain type, relative conservation of amino acids at the specific sequence position based on multiple sequence alignment, indications of folding essential residue (FER) based on the relationship of the residue conservation to the intra-chain contacts and Calpha-Calpha and Cbeta-Cbeta distance geometry. Specific emphasis in SMS is given to interface forming residues (IFR)-amino acids that define the interactive portion of the protein surfaces. SMS may simultaneously display and analyze previously superimposed structures. PDB updates trigger SMS updates in a synchronized fashion. SMS is freely accessible for public data at http://www.cbi.cnptia.embrapa.br, http://mirrors.rcsb.org/SMS and http://trantor.bioc.columbia.edu/SMS. PMID:12824333

  7. Personality trait structure as a human universal.

    PubMed

    McCrae, R R; Costa, P T

    1997-05-01

    Patterns of covariation among personality traits in English-speaking populations can be summarized by the five-factor model (FFM). To assess the cross-cultural generalizability of the FFM, data from studies using 6 translations of the Revised NEO Personality Inventory (P.T. Costa & R. R. McCrae, 1992) were compared with the American factor structure. German, Portuguese, Hebrew, Chinese, Korean, and Japanese samples (N = 7,134) showed similar structures after varimax rotation of 5 factors. When targeted rotations were used, the American factor structure was closely reproduced, even at the level of secondary loadings. Because the samples studied represented highly diverse cultures with languages from 5 distinct language families, these data strongly suggest that personality trait structure is universal. PMID:9145021

  8. The structure of phenotypic personality traits.

    PubMed

    Goldberg, L R

    1993-01-01

    This personal historical article traces the development of the Big-Five factor structure, whose growing acceptance by personality researchers has profoundly influenced the scientific study of individual differences. The roots of this taxonomy lie in the lexical hypothesis and the insights of Sir Francis Galton, the prescience of L. L. Thurstone, the legacy of Raymond B. Cattell, and the seminal analyses of Tupes and Christal. Paradoxically, the present popularity of this model owes much to its many critics, each of whom tried to replace it, but failed. In reaction, there have been a number of attempts to assimilate other models into the five-factor structure. Lately, some practical implications of the emerging consensus can be seen in such contexts as personnel selection and classification. PMID:8427480

  9. Exploratory structural equation modeling of personality data.

    Booth, Tom; Hughes, David J

    2014-06-01

    The current article compares the use of exploratory structural equation modeling (ESEM) as an alternative to confirmatory factor analytic (CFA) models in personality research. We compare model fit, factor distinctiveness, and criterion associations of factors derived from ESEM and CFA models. In Sample 1 (n = 336) participants completed the NEO-FFI, the Trait Emotional Intelligence Questionnaire-Short Form, and the Creative Domains Questionnaire. In Sample 2 (n = 425) participants completed the Big Five Inventory and the depression and anxiety scales of the General Health Questionnaire. ESEM models provided better fit than CFA models, but ESEM solutions did not uniformly meet cutoff criteria for model fit. Factor scores derived from ESEM and CFA models correlated highly (.91 to .99), suggesting the additional factor loadings within the ESEM model add little in defining latent factor content. Lastly, criterion associations of each personality factor in CFA and ESEM models were near identical in both inventories. We provide an example of how ESEM and CFA might be used together in improving personality assessment. PMID:24682748

    We describe the concept, strategy, and initial results of the Millennium Villages Project and implications regarding sustainability and scalability. Our underlying hypothesis is that the interacting crises of agriculture, health, and infrastructure in rural Africa can be overcome through targeted public-sector investments to raise rural productivity and, thereby, to increased private-sector saving and investments. This is carried out by empowering impoverished communities with science-based interventions. Seventy-eight Millennium Villages have been initiated in 12 sites in 10 African countries, each representing a major agroecological zone. In early results, the research villages in Kenya, Ethiopia, and Malawi have reduced malaria prevalence, met caloric requirements, generated crop surpluses, enabled school feeding programs, and provided cash earnings for farm families.

    Derived from Hipparcos and Tycho observations, the Millennium Star Atlas is a set of 1548 charts covering the entire sky to about magnitude 11. It stands apart from all previous printed atlases in completeness to magnitude 10 and in uniformity around the sky. The generous chart scale has made possible a number of innovations never before seen in a star atlas: arrows on high-proper-motion stars, double-star ticks conveying separation and position angle for a specific modern epoch, distance labels for nearby stars, and variable stars coded by amplitude, period, and type. Among the nonstellar objects plotted, more than 8000 galaxies are shown with aspect ratio and orientation.

  16. State Effect of Traumatic Experience on Personality Structure

    2012-01-01

    Objective Personality is defined as the trait-like qualities of a person. However, it has been recently suggested that the state effect of a situation leads to changes in scores on personality assessments. We predicted that traumatic experiences would induce changes not only in personality scores but also in the factor structures of personality assessments. Methods MethodsaaWe conducted a cross-sectional, case-controlled study using two data sets: a traumatized adolescent sample (n=71) and a non-traumatized adolescent sample (n=296). Personality factor structures were compared between the two samples using exploratory factor analyses for 25 lower-ordered subscales of the Temperament and Character Inventory (TCI). In the non-traumatized sample, evaluation of the scree plot suggested a five-factor solution supporting TCI's original seven-factor model. Results The traumatized sample showed a three-factor structure representing a biological factor, a social factor and an existential factor. This decrease in number of personality factors was caused by strengthened correlations among personality subscales related to coping with traumatic situations. Cloninger's psychobiological model of personality (i.e., temperament-character) was adequate in capturing personality traits of non-traumatized adolescents, but the tripartite view of existential psychology (i.e., body-mind-spirit) clearly corresponded to the factor structure of the traumatized adolescents. Conclusion The three-factor solution of the present traumatized group is consistent with the tripartite model of personality (i.e., body-mind-spirit), while the five-factor solution of the non-traumatized group corresponds to Cloninger's seven-factor model. This is the first study to describe the state effects of traumatic experiences on personality structure. PMID:23251200

    2015-01-01

    This study explored how individuals apply features of personality disorders (PDs) to peers. Members of groups nominated peers who exhibited symptoms for each of the 10 PDs in the DSM–IV. Data were gathered in 2 samples: 1st-year college students (n = 1,440) and Air Force recruits (n = 2,075). The peer method reliably identified group members exhibiting specific PD features. Factor analyses identified a clearly interpretable structure relevant to the pathological personality constructs being assessed. The structure replicated well across samples and showed expected relationships to broader models of normal personality. However, cross-method correlations of factor scores were only moderate, suggesting that peer reports are reliably different from self-reports regarding the presence of pathological personality traits.

  2. Dispositional empathy and the hierarchical structure of personality.

    PubMed

    Mooradian, Todd A; Davis, Mark; Matzler, Kurt

    2011-01-01

    Personality psychology has recognized a fundamental 5-factor structure that has integrated and organized theory and research. Nevertheless, personality-like differences beyond that structure have been identified. In heretofore unrelated research, dispositional empathy has been an essential construct in understanding human development, behavior, and interpersonal relationships. Addressing a gap in the literature, we map multidimensional dispositional empathy into 2 versions of the 5-factor space. Empathic concern is closely related to agreeableness, and personal distress is closely related to neuroticism. Perspective taking has complex, interstitial relationships with the 5 factors. In contrast, fantasy is not well explained by the 5 factors. We discuss the implications of these findings for understanding dispositional empathy and for understanding the 5-factor structure, its correlates in emotional processes and experiences, and its limits.

  3. The impact of acquiescence on the evaluation of personality structure.

    PubMed

    Rammstedt, Beatrice; Farmer, Richard F

    2013-12-01

    Acquiescence, or the tendency to respond to descriptions of conceptually distinct personality attributes with agreement/affirmation (acceptance acquiescence) or disagreement/opposition (counter-acquiescence), has been widely recognized as a source of bias that can substantially alter interitem correlations within scales. Acquiescence is also known to operate differently among some groups of persons; it is, for example, more pronounced among individuals with less formal education. Consequently, the biasing effects of acquiescence are of particular concern when the dimensionality underlying the item set of a measure is examined with representative samples comprised of persons with varying levels of educational attainment and evaluated with correlation-based statistical methods such as factor analysis. In the present study, we extended our earlier research by investigating the biasing effect of acquiescence on personality factor structures derived from the full-scale version of the Big Five Inventory (BFI) when administered to a large sample (N = 1,427) selected to be representative of Germany's adult population. Consistent with previous findings based on a short-scale version of the BFI, factor analyses of the unadjusted BFI item set failed to replicate the expected Big Five-factor structure in the low/medium and high educational groups, with distortions in factor structure more pronounced in the former group. Once acquiescence was controlled in the item responses for both groups, however, the obtained factor structures were consistent with the Big Five framework. The implications of acquiescence on the evaluation of the factor structure of personality inventories and for the validity of personality assessments are discussed. PMID:23815112

    2016-04-01

    We described the development of a taxonomy of Persian personality-descriptive terms in two studies. In Study 1, judges scanned Persian dictionaries and several Persian novels for person-descriptive terms. The resulting set of person-descriptive terms was classified into different categories of description, including the category of dispositional trait-descriptive adjectives. Of the 544 most familiar traits, 126 traits were selected to collect self-ratings. In Study 2, self-ratings were provided by 2400 students. Ratings were factor analysed (Principal Components Analysis) followed by Varimax rotation. Factor structures with two to six factors were discussed. The two-factor structure and the three-factor structure confirm the Big Two and the Big Three, respectively. Of the structures with five and six factors, the five-factor structure appears to be the more appropriate choice, with the factors labelled Morality, Positive versus Negative Emotionality, Achievement, Thoughtfulness and Affection. Gender differences were measured on both the five-factor structure and the six-factor structure. The discussion section emphasised both cross-cultural commonalities and cultural deviations in reference to the Big Five. PMID:25534020

    NASA's New Millennium Space Technology 9 (ST-9) mission is the latest of a series of in-space technology validation activities that began in 1996 with Deep Space 1. ST-9 is an integrated system validation project and part of New Millennium Program effort to identify the technological capabilities needed for future space science missions and the technology advances that require validation in deep space to help provide those capabilities. The ST-9 mission will validate one of five technology capabilities that NASA Associate Administrator has selected as candidates. The five technology capabilities under consideration are of great relevance to the full breadth of the NASA's Space Science endeavor and are based on input from the space science community for guidance and concurrence. NASA prepared a NASA Research Announcement (NRA) that solicited proposals for technology advances to provide needed capability for the following technology capability areas: 1) Solar sail capability-design metrics, scaling, deployment, propulsion and attitude control. 2) Large Space Telescope-structure and control dynamics, materials, structures, actuators, controls for fabrication, packaging and deployment, optical correction and active figure control, thermal control at cryogenic temperatures. 3) Formation Flying- autonomous operations, intersatellite communications, spacecraft formation control, and relative position estimation. 4) Aerocapture- system and performance modeling, aerodynamics and aerothermodynamics, thermal protection systems and structures, and guidance, navigation, and control. 5) Pinpoint Landing and Hazard Avoidance-sensors/algorithms for guidance and navigation, aerodynamic/propulsive maneuvering system options, terrain sensing and hazard recognition systems, and terrain sensors. The technology providers were selected to provide needed technology advances in these areas in FY 2005. One these five technologies capability areas will be selected in a timeframe

    2000-01-01

    The New Millennium Program (NMP) is a NASA technology program that focuses on the validation of advanced spacecraft and instrumentation technologies in space. This program specifically seeks technologies that could significantly benefit future space and Earth science missions by enabling new science capabilities and reducing life cycle costs. These technologies must also require a validation in space to mitigate risks to the first science users, and provide cross-cutting benefits to both NASA's Earth and Space Science enterprises. The NASA Office of Earth Science (OES) directed the NMP to focus the third Earth Observing mission, E03, on innovative measurement concepts that would facilitate remote sensing observations from orbits beyond conventional low-Earth orbit (LEO). These orbits include geosynchronous orbits, highly elliptical orbits, mid-Earth and high-Earth orbits, and other unique vantage points such as L1 and L2. To maximize the input from the Earth science community, a NASA Research Announcement (NRA) was released to solicit innovative measurement concepts for this NMP flight. Because the NMP is a technology validation program, rather than a conventional science program, the NRA required that these measurement concepts employ revolutionary technologies and/or measurement strategies that will enable future science missions from orbits beyond LEO. Another requirement was that a validation in space was needed to reduce real or perceived risks of this concept to future science users. The proposals submitted in response to this NRA were peer reviewed by the NASA OES. The measurement concepts selected through this process will be summarized in this presentation. The E03 measurement concept NRA did not solicit complete mission concepts or flight hardware. Instead, the selected investigators will join integrated project formulation teams to define the mission for the demonstration of the measurement technique and participate in mission design trades and

    2016-01-01

    We demonstrate that observer-rated factor structure of personality in centenarians is congruent with the normative structure. Prevalence of cognitive impairment, which has previously been linked to changes in personality in younger samples, is high in this age group, requiring observer ratings to obtain valid data in a population-based context. Likewise, the broad range of cognitive functioning necessitates synthesis of results across multiple measures of cognitive performance. Data from 161 participants in the Georgia Centenarian Study (GCS, MAge = 100.3 years, 84% women, 20% African American, 40% community-dwelling, 30% low cognitive functioning) support strong overall correspondence with reference structure (full sample: .94; higher cognitive functioning: .94; lower cognitive functioning: .90). Centenarians with lower cognitive functioning are higher on neuroticism and lower on openness to experience, agreeableness, and conscientiousness. Facet-level differences (higher N1–N6: anxiety, hostility, depression, self-consciousness, impulsiveness, vulnerability to stress; lower E1: warmth, lower O4–O6: actions, ideas, values; lower A1, A3, A4: trust, altruism, compliance; C1, C5: competence, self-discipline) are also observed. Multivariate factor-level models indicate only neuroticism of the five broad factors predicts membership in cognitively impaired group; facet-level models showed that lower-order scales from three of the five domains were significant. Centenarians with: higher self-consciousness (N4), impulsiveness (N5), and deliberation (C6), but lower ideas (O5), compliance (A4), and self-discipline (C5) were more likely to be in the lower cognitive functioning category. Results present first normative population-based data for personality structure in centenarians and offer intriguing possibilities for the role of personality in cognitive impairment centered on neuroticism.

    2010-01-01

    We report an investigation of the genesis and interpretation of simple structure in personality data using two very different self-reported data sets. The first consists of a set of relatively unselected lexical descriptors, whereas the second is based on responses to a carefully constructed instrument. In both data sets, we explore the degree of simple structure by comparing factor solutions to solutions from simulated data constructed to have either strong or weak simple structure. The analysis demonstrates that there is little evidence of simple structure in the unselected items, and a moderate degree among the selected items. In both instruments, however, much of the simple structure that could be observed originated in a strong dimension of positive vs. negative evaluation. PMID:20694168

    1996-12-31

    The New Millennium Program (NMP) has been established to accelerate the infusion of breakthrough technologies into NASA space science missions. The goal of this technology infusion is to fulfill the NASA vision of frequent, low-cost missions to deep space and to plant Earth. Power is one of the most important keys to cost-effective space science missions. The power subsystem comprises over 25 percent of the mass of a typical space orbiter type spacecraft. The problems of power will become even more acute in the new millennium as deep space missions are asked to go farther from the Sun and get to their destinations faster. Several power technology proposals were submitted to the NMP through its Modular and Multifunctional Systems Integrated Product Development Team (IPDT). The proposals described in this paper received the most consideration and in several cases resulted in the technology being selected for flight on one of the NMP missions. The technologies discussed here are: SCARLET array, Light Flexible array, lithium ion battery, cold temperature battery, inflatable concentrators and a related technology -- Multifunctional Structures.

    This symposium identified the major challenges in biomedical research that will benefit from bioengineering applications. Attention was focused on the important role that bioengineers will play in future advances in biomedical research. There was considerable discussion about how to integrate bioengineering with biological research in meeting the challenges of the twenty-first century. Symposium presenters showcased the accomplishments of NIH-funded bioengineering researches and increased the visibility of bioengineering to NIH leaders, staff, and members of the intramural and extramural research community. Recommendations were also made for future NIH-funded research projects. Attention was also placed on how basic bioengineering research can lead to commercialization of new health care technology and therefore maintain the nation's leadership in this important area. New products, from biotechnology and novel devices for diagnosis and treatment, are marketed through interactions between universities, medical centers, small start-up firms, and larger, more established companies. In the United States the gross revenue of the bioengineering private sector industry involved in the manufacture of health care products already exceeds $40 billion. More then 750 persons attended this bioengineering symposium. Over 110 scientific posters and exhibits relating to biology and medicine were presented. They provided a forum for showcasing NIH-funded bioengineering projects and fostered future collaboration among academic investigators, industry, and members of the small business community. The contributions of Pugwash bioengineer, Maciej Natecz, a member of the Polish Academy of Sciences, was recognized by the Conference Planning Committee. He was honored for his work in nuclear disarmament. Indian medical scientists should note that this symposium provided a framework for the development of technology in biomedical sciences during the Twenty-First Century. Major

    1998-07-01

    This article prognosticates where periodontology will be in the next millennium. The forecasting of such events is wrought with confusion because such predictions are shadowed by bias, dogmatism, prejudice, experiences, and opinions from either a closed or open mind. The results of the survey from 101 periodontists reflect opinions from varied backgrounds, years of clinical experience, and individual levels of success or failure. The responses cannot be tested for accuracy or duplicated by another survey except to wait out the test of time for the year 2025. Clinicians will be challenged to make decisions on accepting new techniques and concepts as these are brought into the therapeutic fold of periodontics. The clinician will be met with new possibilities as a paradigm shift is inevitable for periodontal practice in the next millennium. After all, who would have thought in the 1960s, the soft tissue augmentation era, that 22 years later in 1982, the regeneration of the lost attachment apparatus (alveolar bone, cementum, and periodontal ligament) would become a reality. This survey strongly suggests that by the end of the first quarter of the twenty-first century, local delivery of antimicrobials, growth and differentiation factors, and root biomodification agents will have a major impact on the practice of periodontics. One thing is certain, in the next millennium, considering the responses from this survey, a new era in periodontics will be here. By the year 2025, the research, development, and dissemination of new periodontal knowledge will be beyond the imagination from what was considered usual and customary for the twentieth century.

    During the 20th century our understanding of genetics and the processes of gene expression have undergone revolutionary change. Improved technology has identified the components of the living cell, and knowledge of the genetic code allows us to visualize the pathway from genotype to phenotype. We can now sequence entire genes, and improved cloning techniques enable us to transfer genes between organisms, giving a better understanding of their function. Due to the improved power of analytical tools databases of sequence information are growing at an exponential rate. Soon complete sequences of genomes and the three-dimensional structure of all proteins may be known. The question we face in the new millennium is how to apply this data in a meaningful way. Since the genes carry the specification of an organism, and because they also record evolutionary changes, we need to design a theoretical framework that can take account of the flow of information through biological systems.

    In the first study, we administered the 40-item Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988) to 843 female and 843 male college students, most of whom were Euro-American, to comprehensively assess the NPI factor structure using confirmatory factor analysis. Initial exploratory common factor analyses (N = 724) revealed a 2-factor model (Leadership/Authority and Exhibitionism/Entitlement). Subsequently, we used confirmatory factor analysis in a separate sample (N = 724) to evaluate the Emmons (1987) 4-factor model, the Raskin and Terry (1988) 7-factor model, the Kubarych, Deary, and Austin (2004) 2- and 3-factor models, and our 2-factor model. Finally, we assessed construct validity by correlating the scale scores with the Five-factor model of personality in an independent sample (N = 238). The 2-factor models for the NPI we obtained in this study and by Kubarych et al. (2004) appeared to be the most parsimonious models, with both a good fit to the data and satisfactory internal consistency values; so they are recommended for use. However, additional NPI research is needed to rescale, modify, or omit several NPI items and develop gender-equivalent items. PMID:18925501

    Millon's (1987) circular model of personality disorders was examined in a large sample of psychiatric patients (N = 2,366) who completed the Millon Clinical Multiaxial Inventory-III (MCMI-III; Millon, 1997) as part of routine assessment after presentation for treatment. Principal components analyses were conducted to identify the first two dimensions in MCMI-III base rate scores, weighted and unweighted raw scores, and nonoverlapping scale scores. Similar analyses were made on these scores when acquiescence was partialled out. Circular plots of the scales were examined against Millon's hypothesized arrangement and the model was tested using confirmatory factor analysis. Results replicated those of Strack, Lorr, and Campbell (1990) with the MCMI-II. Millon's horizontal Impassive-Expressive dimension was recovered in both regular and residual scores but the vertical axis appeared to represent an Impulsivity-Compulsivity dimension rather than the Autonomous-Enmeshed continuum envisioned by Millon. Although scale order followed Millon's predictions for the most part, a number of departures from theoretical expectations were noted and none of the score sets yielded a good fit to the hypothetical structure. Millon's model appears to have promise as a circumplex that can encompass all of the personality disorders but changes are needed to rectify discrepancies between the theory and empirical findings.

  3. A Fairbairnian structural analysis of the narcissistic personality disorder.

    PubMed

    Celani, David P

    2014-06-01

    Fairbairn's structural theory is based on the developing child's need to dissociate actual events between himself or herself and his or her objects that are excessively rejecting in order to contine an uninterrupted, pristine attachment to them. This eventuates in three selves in relation to three objects: One pair is conscious (the central ego which relates to the ideal object), while the other two pairs (the antilibidinal ego, which relates to the rejecting object, and the libidinal ego, which relates to the exciting object) are mostly held in the unconscious. Fairbairn saw the fluid relationship between the two split-off pairs of unconscious part selves and the conscious central ego as the primary dynamic of the human personality. The author proposes a specific variation in Fairbairn's structural theory to account for the development of narcissism. Specifically, this disorder is viewed as the result of a developmental history in which the child finds himself or herself in an exceedingly hostile interpersonal environment that precludes the child from using an idealized version either of his or her parental objects as the "exciting object." The child therefore substitutes a grandiose view of himself or herself as the exciting object. This defense deflects external influences and replaces relationships with external objects with a closed internal world that is comprised of an admiring part-self basking in reflected love from its relationship with an exciting part-object.

    Personal naming practices exist in all human groups and are far from random. Rather, they continue to reflect social norms and ethno-cultural customs that have developed over generations. As a consequence, contemporary name frequency distributions retain distinct geographic, social and ethno-cultural patterning that can be exploited to understand population structure in human biology, public health and social science. Previous attempts to detect and delineate such structure in large populations have entailed extensive empirical analysis of naming conventions in different parts of the world without seeking any general or automated methods of population classification by ethno-cultural origin. Here we show how ‘naming networks’, constructed from forename-surname pairs of a large sample of the contemporary human population in 17 countries, provide a valuable representation of cultural, ethnic and linguistic population structure around the world. This innovative approach enriches and adds value to automated population classification through conventional national data sources such as telephone directories and electoral registers. The method identifies clear social and ethno-cultural clusters in such naming networks that extend far beyond the geographic areas in which particular names originated, and that are preserved even after international migration. Moreover, one of the most striking findings of this approach is that these clusters simply ‘emerge’ from the aggregation of millions of individual decisions on parental naming practices for their children, without any prior knowledge introduced by the researcher. Our probabilistic approach to community assignment, both at city level as well as at a global scale, helps to reveal the degree of isolation, integration or overlap between human populations in our rapidly globalising world. As such, this work has important implications for research in population genetics, public health, and social science adding new

    Wooden circular structures, presumed archaeologically as a structure related with ritual of ancient people in the Final Jomon period, are specific to archaeological sites excavated mainly in the coastal region around Noto peninsula, central Japan. So far, only few attempts have been made at chronological studies on these wooden structures. 14C dating has been attempted to wooden poles forming the structures, which had been excavated at the Mawaki archaeological site, Ishikawa prefecture, central Japan, to examine construction period of the structures. It was revealed that these structures were constructed in the Final Jomon period, most probably within 900-400 cal BC. In addition, we have tried wiggle matching of 14C ages for several annual rings separated from three and two poles that were constituting two circular structures, the oldest and the newest ones. 14C dates of annual rings measured with AMS were wiggle-matched to IntCal04 data sets by Bayesian statistics. The results indicated that the construction period of these wooden structures can be placed within ca. 820-680 cal BC, being narrowed by about 350 calendar years successfully.

    The schizotypal personality questionnaire (SPQ) is used to characterize schizotypy, a complex construct helpful for the investigation of schizophrenia-related psychopathology and putative endophenotypes. The SPQ factor structure at item level has been rarely replicated and no study had tested a bifactor model of the SPQ so far. The unidimensional, the correlated, the second-order and the bifactor models of the SPQ were tested to evaluate whether the items converge into a major single factor defining the schizotypy-proneness of the participants, to be used for grouping purpose. Parallel principal component analysis (PCA) and confirmatory factor analysis (CFA) were used to determine the optimal number of factors and components in a cross-sectional, survey design involving 649 college students (males: 47%). The first-order, nine-subscale model was confirmed by CFA in the whole sample. The best evidence from parallel PCA in the training set was in favor of a two-factor model; the bifactor implementation of this model showed good fit in the subsequent CFA. Two main dimensions of positive and negative symptoms underlie schizotypy in non-clinical samples, entailing specific risk of psychosis. On a measurement level, the study provided support for the use of the total scores of the SPQ to characterize schizotypy. PMID:26607431

    The spotlight on borderline personality disorder (BPD) has been growing in recent years, with the number of papers discussing potential causes and triggers of the disorder rapidly on the increase. Also on the increase, though still lacking sufficient numbers to produce well-supported hypotheses, are studies employing neuroimaging techniques as investigative tools in BPD. In this review, we investigate the current state and findings of neuroimaging studies in BPD, focusing in particular, on the studies examining structural, functional, and neurometabolic abnormalities in the disorder. Some suspected trends in the data are highlighted, including reductions in the hippocampi and amygdalae of BPD patients compared to healthy controls, exaggerated amygdala activity in BPD patients when confronted with emotion-related stimulus, and negative correlations between increases in left amygdalar creatine and reductions in amygdalar volume, reductions in absolute N-acetylaspartate concentration in the dorsolateral prefrontal cortex of BPD patients, and increases in glutamate concentration in the anterior cingulate cortices of BPD patients. We also discuss the limitations of some of the current studies including hindrances due to sample effects and techniques used and the potential of future neuroimaging research in BPD. PMID:22252376

    Increasing evidence indicates that normal and abnormal personality can be treated within a single structural framework. However, identification of a single integrated structure of normal and abnormal personality has remained elusive. Here, a constructive replication approach was used to delineate an integrative hierarchical account of the structure of normal and abnormal personality. This hierarchical structure, which integrates many Big Trait models proposed in the literature, replicated across a meta-analysis as well as an empirical study, and across samples of participants as well as measures. The proposed structure resembles previously suggested accounts of personality hierarchy and provides insight into the nature of personality hierarchy more generally. Potential directions for future research on personality and psychopathology are discussed. PMID:15631580

    Species comparisons of personality structure (i.e. how many personality dimensions and the characteristics of those dimensions) can facilitate questions about the adaptive function of personality in nonhuman primates. Here we investigate personality structure in the brown capuchin monkey (Sapajus apella), a New World primate species, and compare this structure to those of chimpanzees (Pan troglodytes), orangutans (Pongo spp.), and rhesus macaques (Macaca mulatta). Brown capuchins evolved behavioral and cognitive traits that are qualitatively similar to those of great apes, and individual differences in behavior and cognition are closely associated with differences in personality. Thus, we hypothesized that brown capuchin personality structure would overlap more with great apes than with rhesus macaques. We obtained personality ratings from seven sites on 127 brown capuchin monkeys. Principal-components analysis identified five personality dimensions (Assertiveness, Openness, Neuroticism, Sociability, and Attentiveness), which were reliable across raters and, in a subset of subjects, significantly correlated with relevant behaviors up to a year later. Comparisons between species revealed that brown capuchins and great apes overlapped in personality structure, particularly chimpanzees in the case of Neuroticism. However, in some respects (i.e. capuchin Sociability and Openness) the similarities between capuchins and great apes were not significantly greater than those between capuchins and rhesus macaques. We discuss the relevance of our results to brown capuchin behavior, and the evolution of personality structure in primates. PMID:23668695

    Simulations of galaxy evolution aim to capture our current understanding as well as to make predictions for testing by future experiments. Simulations and observations are often compared in an indirect fashion: physical quantities are estimated from the observational data and compared to models. However, many applications can benefit from a more direct approach, where the observing process is also simulated, so that the models are seen fully from the observer's perspective. To facilitate this, we have developed the Millennium Run Observatory (MRObs), a theoretical virtual observatory which uses virtual telescopes to `observe' semi-analytic galaxy formation simulations based on the suite of Millennium Run (MR) dark matter simulations. The MRObs produces data that can be processed and analysed using the standard observational software packages developed for real observations. At present, we produce images in 40 filters covering the rest-frame ultraviolet to infrared for two stellar population synthesis models, for three different models of absorption by the intergalactic medium, and in two cosmologies (Wilkinson Microwave Anisotropy Probe year 1 and 7). Galaxy distributions for a large number of mock light cones can be `observed' using models of major ground- and space-based telescopes. The data include light cone catalogues linked to structural properties of galaxies, pre-observation model images, mock telescope images and Source Extractor products that can all be traced back to the higher level dark matter, semi-analytic galaxy and light cone catalogues available in the MR data base. Here, we describe our methods and announce a first public release of simulated observations that emulate a large number of extragalactic surveys [e.g. Sloan Digital Sky Survey, Canada-France-Hawaii Telescope Legacy Survey (CFHT-LS), Great Observatories Origins Deep Survey (GOODS), GOODS/Early Release Science (ERS), Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS

    For the past 43 years, NASA has devoted its facilities, labor force, and expertise to sharing the abundance of technology developments used for its missions with the nation's industries. These countless technologies have not only successfully contributed to the growth of the U.S. economy, but also to the quality of life on Earth. For the past 25 years, NASA's Spinoff publication has brought attention to thousands of technologies, products, and services that were developed as a direct result of commercial partnerships between NASA and the private business sector. Many of these exciting technologies included advances in ceramics, computer technology, fiber optics, and remote sensing. New and ongoing research at the NASA field centers covers a full spectrum of technologies that will provide numerous advantages for the future, many of which have made significant strides in the commercial market. The NASA Commercial Technology Network plays a large role in transferring this progress. By applying NASA technologies such as data communication, aircraft de-icing technologies, and innovative materials to everyday functions, American consumers and the national economy benefit. Moving forward into the new millennium, these new technologies will further advance our country's position as the world leader in scientific and technical innovation. These cutting-edge innovations represent the investment of the U.S. citizen in the Space Program. Some of these technologies are highlighted in Spinoff 2001, an example of NASA's commitment to technology transfer and commercialization assistance. This year's issue spotlights the commercial technology efforts of NASA's John F. Kennedy Space Center. Kennedy's extensive network of commercial technology opportunities has enabled them to become a leader in technology transfer outreach. This kind of leadership is exemplified through Kennedy's recent partnership with the State of Florida, working toward the development of the Space Experiment

    As the century has just changed for the Western calendar it should be borne in mind that for a vast part of the world the centuries are rolling at a different time and under different conditions. So, although we live and trade in a "global village", we are yet divided by time, space, and ideologies. The hope is that the 21st century will enable us to have a closer look at each other and that the global networks, the web sites, and the electronic mailing systems, will work as a bridge rather than as a new means of widening the gaps. This article is a plea for a better understanding of the different priorities and views that Islamist women have of themselves, of their place in history, and what it is that they need to fight for. It is also a call for the universality of sisterhood and a wish that the solidarity that was forged in the latter part of the 20th century will not be fragmented into smithereens in the new millennium.

  1. Use of structured personality survey techniques to indicate operator response to stressful situations

    SciTech Connect

    Waller, M.A.

    1990-01-01

    Under given circumstances, a person will tend to operate in one of four dominant orientations: (1) to perform tasks; (2) to achieve consensus; (3) to achieve understanding, or (4) to maintain structure. Historically, personality survey techniques, such as the Myers-Briggs type indicator, have been used to determine these tendencies. While these techniques can accurately reflect a person's orientation under normal social situations, under different sets of conditions, the same person may exhibit other tendencies, displaying a similar or entirely different orientation. While most do not exhibit extreme tendencies or changes of orientation, the shift in personality from normal to stressful conditions can be rather dramatic, depending on the individual. Structured personality survey techniques have been used to indicate operator response to stressful situations. These techniques have been extended to indicate the balance between orientations that the control room team has through the various levels of cognizance.

    Smart houses are considered a good alternative for the independent life of older persons and persons with disabilities. Numerous intelligent devices, embedded into the home environment, can provide the resident with both movement assistance and 24-h health monitoring. Modern home-installed systems tend to be not only physically versatile in functionality but also emotionally human-friendly, i.e., they may be able to perform their functions without disturbing the user and without causing him/her any pain, inconvenience, or movement restriction, instead possibly providing him/her with comfort and pleasure. Through an extensive survey, this paper analyzes the building blocks of smart houses, with particular attention paid to the health monitoring subsystem as an important component, by addressing the basic requirements of various sensors implemented from both research and clinical perspectives. The paper will then discuss some important issues of the future development of an intelligent residential space with a human-friendly health monitoring functional system. PMID:15218937

    Wakeling, J.

    There are many new satellite communication systems that are either on the verge of commercial service or in the advanced planning and design stages for launch in the next millennium. Many will address what are considered to be new markets for satellites, using services and applications originally developed for terrestrial networks. Many of these services are network oriented and this will require a step change in the way that the satellite resource is managed if these systems are to succeed. This paper discusses these issues and offers some thoughts on what additional future services this change in approach may generate in the next millennium.

  6. Empirical, theoretical, and practical advantages of the HEXACO model of personality structure.

    PubMed

    2007-05-01

    The authors argue that a new six-dimensional framework for personality structure--the HEXACO model--constitutes a viable alternative to the well-known Big Five or five-factor model. The new model is consistent with the cross-culturally replicated finding of a common six-dimensional structure containing the factors Honesty-Humility (H), Emotionality (E), eExtraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to Experience (O). Also, the HEXACO model predicts several personality phenomena that are not explained within the B5/FFM, including the relations of personality factors with theoretical biologists' constructs of reciprocal and kin altruism and the patterns of sex differences in personality traits. In addition, the HEXACO model accommodates several personality variables that are poorly assimilated within the B5/FFM. PMID:18453460

    The epidemiology of deaths due to vaccine-preventable diseases has been significantly and positively altered through the use of vaccines. Despite this, significant challenges remain in vaccine development and use in the third millennium. Both new (Ebola, Chikungunya, Zika, and West Nile) and re-emerging diseases (measles, mumps, and influenza) require the development of new or next-generation vaccines. The global aging of the population, and accumulating numbers of immunocompromised persons, will require new vaccine and adjuvant development to protect large segments of the population. After vaccine development, significant challenges remain globally in the cost and efficient use and acceptance of vaccines by the public. This article raises issues in these two areas and suggests a way forward that will benefit current and future generations. PMID:27039875

  10. Diverse Family Structures and the Care of Older Persons.

    2015-09-01

    Demographic and social trends lead to a variety of micro-level and internal structural contexts that influence caregiving in families with older members. The results of macro-level changes have received little focused attention in the aging literature, where much of the caregiving research has addressed issues within the context of traditional family structure. Yet the conventional nuclear family model is increasingly uncommon as new, pluralistic models of family life are emerging in contemporary society. The majority of elder care is provided by relatives, albeit with varying patterns of involvement and responsibility across family structures. Both conventional and pluralistic families face challenges in meeting the care needs of their oldest members, leaving some older adults at risk of having unmet needs. Additional research on family risk and resilience related to the care of older relatives is warranted, particularly with respect to pluralistic models of family life. PMID:26300190

    The University Personality Inventory, a mental health instrument for college students, is frequently used for screening in China. However, its unidimensionality has been questioned. This study examined its dimensions to provide more information about the specific mental problems for students at risk. Four subsamples were randomly created from a sample (N = 6,110; M age = 19.1 yr.) of students at a university in China. Principal component analysis with Promax rotation was applied on the first two subsamples to explore dimension of the inventory. Confirmatory factor analysis was conducted on the third subsample to verify the exploratory dimensions. Finally, the identified factors were compared to the Symptom Checklist-90 (SCL-90) to support validity, and sex differences were examined, based on the fourth subsample. Five factors were identified: Physical Symptoms, Cognitive Symptoms, Emotional Vulnerability, Social Avoidance, and Interpersonal Sensitivity, accounting for 60.3% of the variance. All the five factors were significantly correlated with the SCL-90. Women scored significantly higher than men on Cognitive Symptoms and Interpersonal Sensitivity. PMID:25933045

    The aim of this study was to explore the relations between gambling, brain emotion systems, personality, self/other perception, and hopelessness in an Italian community. Dimensions of gambling, positive and negative emotions, self/other perception, personality and hopelessness were assessed in a community sample of 235 adults aged 19-59 years. Two structural models were tested. We found a significant correlation between problem gambling and impulsivity, which in association with aggressivity and negative personality dimensions may help explain the psychopathology factor, i.e. a latent variable involving neurotic personality, hopelessness, high sensation seeking, low metacognitive responsiveness, and disorganized patterns of interpersonal relationships. These results contribute to develop a theoretical framework of gambling in relation with personality factors and provide a new approach for clinical intervention of problem gambling that relies on a solid multidimensional perspective.

    I describe my gradually evolving role as a scientist from my birth in Frankfurt (Germany) to my education in the UK, my post-doc years and my experiences as an independent investigator at Purdue University1. I discuss the significance of my post-doctoral work in Minnesota where I had my first encounter with an electronic computer and subsequently in Cambridge where I participated in the first structure determination of proteins. After six years back in England my family moved to Indiana (USA) where my home remains to this day. At Purdue University I first studied the structure of enzymes and in the process I discovered the organization and slow evolution of protein domains, each with a specific function. With this success I started what had been on my mind already for a long time, namely the structural analysis of viruses. Initially we studied plant viruses but then switched to small RNA animal viruses, discovering that some plant and animal RNA viruses have closely similar structures and therefore presumably had a common evolutionary origin. Next I became interested in somewhat larger viruses that had lipid membrane envelopes. In turn that has led to the study of very large dsDNA viruses as big as small bacteria as well as studies of bacterial viruses that require complex molecular motors for different parts of their life cycle. While developing crystallographic techniques for the study of viruses it has become progressively more apparent that electron microscopy is an important new tool that is likely to eclipse x-ray crystallography in the next decade.

    Although paranoid personality is one of the most commonly diagnosed personality disorders and is associated with numerous negative life consequences, relatively little is known about the structural properties of this condition. This study examines whether paranoid personality traits represent a latent dimension or a discrete class (i.e., taxon). In Study 1, the authors conducted taxometric analyses of paranoid personality disorder criteria in a sample of 731 patients participating in the Collaborative Longitudinal Study of Personality Disorders project (Gunderson et al., 2000) who had been administered a semistructured diagnostic interview for personality disorders according to criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994). In Study 2, the authors conducted parallel analyses of the Paranoia scale of the Personality Assessment Inventory (PAI; L. C. Morey, 2007), using data from the PAI community and clinical normative databases. Analyses across both self-report and interview-based indicators offered compelling support for a dimensional structure. Additionally, analyses of external correlates in these data sets suggested that dimensional models demonstrated stronger validity coefficients with criterion measures than did dichotomous models.

    Studies addressing brain correlates of emotional personality have remained sparse, despite the involvement of emotional personality in health and well-being. This study investigates structural and functional brain correlates of psychological and physiological measures related to emotional personality. Psychological measures included neuroticism, extraversion, and agreeableness scores, as assessed using a standard personality questionnaire. As a physiological measure we used a cardiac amplitude signature, the so-called Eκ value (computed from the electrocardiogram) which has previously been related to tender emotionality. Questionnaire scores and Eκ values were related to both functional (eigenvector centrality mapping, ECM) and structural (voxel-based morphometry, VBM) neuroimaging data. Functional magnetic resonance imaging (fMRI) data were obtained from 22 individuals (12 females) while listening to music (joy, fear, or neutral music). ECM results showed that agreeableness scores correlated with centrality values in the dorsolateral prefrontal cortex, the anterior cingulate cortex, and the ventral striatum (nucleus accumbens). Individuals with higher Eκ values (indexing higher tender emotionality) showed higher centrality values in the subiculum of the right hippocampal formation. Structural MRI data from an independent sample of 59 individuals (34 females) showed that neuroticism scores correlated with volume of the left amygdaloid complex. In addition, individuals with higher Eκ showed larger gray matter volume in the same portion of the subiculum in which individuals with higher Eκ showed higher centrality values. Our results highlight a role of the amygdala in neuroticism. Moreover, they indicate that a cardiac signature related to emotionality (Eκ) correlates with both function (increased network centrality) and structure (grey matter volume) of the subiculum of the hippocampal formation, suggesting a role of the hippocampal formation for emotional

  20. Requirements for a reliable millennium temperature reconstruction

    2014-05-01

    Quantitative temperature reconstructions are hampered by several problems. Proxy records are sparse which is witnessed by the fact that roughly half of all available high-resolution millennia-long proxy data have been published in the last five years. Moreover, proxies are inhomogeneously distributed around the globe and they often have coarse temporal resolution. The period of overlap between proxies and instrumental observations - the calibration period - is brief and dominated by a strong warming trend. Furthermore, proxies are often only weakly correlated to temperature and it is common that some form of screening procedure is applied to select only informative proxies. We study the influence of these limitations on the reliability of temperature reconstructions for the previous millennium. This influence depends on the spatial and temporal correlation structure of the surface temperature field. It also depends on the reconstruction methodology. We use gridded surface temperature data from GISTEMP and HadCRUT4 to investigate the geographical distribution of the spatial decorrelation length and of the temporal decorrelation time. The spatial decorrelation length varies with more than a factor of 5 with the largest values in the region dominated by the El Nino-Southern Oscillation. The temporal decorrelation time varies less with typical values of 1-2 years over land and 2-5 years over ocean. We also investigate the correlations between proxies and local temperatures (using the 91 proxies from Christiansen and Ljungqvist 2012) and between local temperatures and the NH mean temperature. These correlations have typical values around 0.3 but cover a wide range from weakly negative to larger than 0.8. The results outlined above allow us to identify regions where the effect of the lack of proxies is most important. They also inform us on the consequences of the short calibration period and on the influence of the recent trend. Finally, we demonstrate the effect of a

    2013-01-01

    Objective: To examine the joint hierarchical structure of two measures of adolescent personality pathology within a community sample of Canadian adolescents. Method: Self-reported data on demographic information and pathological personality traits were obtained from 144 youth (Mage = 16.08 years, SD = 1.30). Personality pathology was measured using the youth-version of the Schedule for Nonadaptive and Adaptive Personality (SNAP-Y; Linde, Stringer, Simms, & Clark, in press) and the Dimensional Personality Symptom Item Pool (DIPSI; De Clercq, De Fruyt, Van Leeuwen, & Mervielde, 2006). Lower-order scales were subjected to structural hierarchical analyses. Results: Scales from the two measures were complementary in defining higher-order traits. Traits at the 4-factor level of the hierarchy (Need for Approval, Disagreeableness, Detachment, and Compulsivity) showed similarities and differences with previous results in adults. Conclusions: The current investigation integrated top-down and bottom-up measures for a comprehensive account of the higher-order hierarchy of adolescent personality pathology. Results are discussed in the context of convergence across approaches and in comparison with previous findings in adult samples. PMID:23970908

    2013-01-01

    Background The assessment of personality organization and its observable behavioral manifestations, i.e. personality functioning, has a long tradition in psychodynamic psychiatry. Recently, the DSM-5 Levels of Personality Functioning Scale has moved it into the focus of psychiatric diagnostics. Based on Kernberg’s concept of personality organization the Structured Interview of Personality Organization (STIPO) was developed for diagnosing personality functioning. The STIPO covers seven dimensions: (1) identity, (2) object relations, (3) primitive defenses, (4) coping/rigidity, (5) aggression, (6) moral values, and (7) reality testing and perceptual distortions. The English version of the STIPO has previously revealed satisfying psychometric properties. Methods Validity and reliability of the German version of the 100-item instrument have been evaluated in 122 psychiatric patients. All patients were diagnosed according to the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) and were assessed by means of the STIPO. Moreover, all patients completed eight questionnaires that served as criteria for external validity of the STIPO. Results Interrater reliability varied between intraclass correlations of .89 and 1.0, Crohnbach’s α for the seven dimensions was .69 to .93. All a priori selected questionnaire scales correlated significantly with the corresponding STIPO dimensions. Patients with personality disorder (PD) revealed significantly higher STIPO scores (i.e. worse personality functioning) than patients without PD; patients cluster B PD showed significantly higher STIPO scores than patients with cluster C PD. Conclusions Interrater reliability, Crohnbach’s α, concurrent validity, and differential validity of the STIPO are satisfying. The STIPO represents an appropriate instrument for the assessment of personality functioning in clinical and research settings. PMID:23941404

    Certain configurations of massive structures projected along the line of sight (LOS) maximize the number of detections of gravitationally lensed z ∼ 10 galaxies. We characterize such LOSs with the étendue σ{sub μ}, the area in the source plane magnified over some threshold μ. We use the Millennium I and Millennium XXL cosmological simulations to determine the frequency of high σ{sub μ} beams on the sky, their properties, and efficient selection criteria. We define the best beams as having σ{sub μ>3} > 2000 arcsec{sup 2}, for a z ∼ 10 source plane, and predict 477 ± 21 such beams on the sky. The total mass in the beam and σ{sub μ>3} are strongly correlated. After controlling for total mass, we find a significant residual correlation between σ{sub μ>3} and the number of cluster-scale halos (>10{sup 14} M {sub ☉} h {sup –1}) in the beam. Beams with σ{sub μ>3} > 2000 arcsec{sup 2}, which should be best at lensing z ∼ 10 galaxies, are 10 times more likely to contain multiple cluster-scale halos than a single cluster-scale halo. Beams containing an A1689-like massive cluster halo often have additional structures along the LOS, including at least one additional cluster-scale (M {sub 200} > 10{sup 14} M {sub ☉} h {sup –1}) halo 28% of the time. Selecting beams with multiple, massive structures will lead to enhanced detection of the most distant and intrinsically faint galaxies.

  13. Nuclear energy for the third millennium

    SciTech Connect

    Teller, E.

    1997-10-01

    The major energy sources of today are expected to last for only a small fraction of the millennium starting three years hence. In the plans of most people, nuclear energy has been ruled out for four separate reasons: 1. The danger of radioactivity from a reactor accident or from reactor products during a long period after reactor shutdown; 2. The proposed fuels, U-235 and also Pu-239, as obtained by presently available procedures will serve only for a limited duration; 3. Energy from nuclear reactors will be more expensive than costs of present alternatives; 4. The possibility of misusing the products for military purposes is an unacceptable danger. The development described below 1 attempts to meet all four objections. Specifically, we propose a structure as an example of future reactors that is deployed two hundred meters underground in loose and dry earth. The reactor is designed to function for thirty years, delivering electrical power on demand up to a level of thousand electrical megawatts. From the time that the reactor is started to the time of its shutdown thirty years later, the functioning is to be completely automatic. This is an obviously difficult condition to fulfill. The most important factor in making it possible is to design and operate the reactor without moving mechanical parts. At the start, the reactor functions on thermal neutrons within a structure containing uranium enriched in U-235 or having an addition of plutonium. That part of the reactor is to deliver energy for approximately one year after which a neighboring portion of the reactor containing thorium has been converted into Th-233 which rather rapidly decays into fissile U-233. This part of the assembly works on fission by fast neutrons. It will heat-up if insufficient thermal energy is withdrawn from the reactor`s core, under the negative feedback action of engineered-in thermostats. Indeed, these specifically designed thermostatic units absorb neutrons if excessive reactor core

    Blais, Mark A; Malone, Johanna C

    2013-05-01

    The revisions proposed for the DSM-5 would greatly alter how personality pathology is conceptualized, assessed, and diagnosed. One aspect of the proposed changes, elimination of four current personality disorders, has raised considerable controversy. The present study attempts to inform this debate by exploring clinicians' views of the structure of Personality Disorders using the current diagnostic system, the DSM-IV. An exploratory factor analysis was conducted on the DSM-IV Personality Disorder criteria using clinician ratings for 280 patients. The factor analysis revealed eight clear and meaningful factors. The eight factors contained all six personality disorders proposed for retention in DSM-5 but also contained clear representations of two disorders (Paranoid and Schizoid) identified for removal from the system. These conditions appear to have clinical utility and their removal may have unintended negative consequences in clinical practice. Dependent and Avoidant criteria also merged to form a new construct with interesting clinical implications. These findings provide new insights into the complex typologies clinicians employ when applying the DSM-IV system to personality disordered patients. Lastly we argue that successful refinement of clinically significant constructs, like diagnostic systems, requires a balanced appraisal of evidence for clinical utility as well as external and internal validity.

    In this article, we describe the development and preliminary psychometric properties of the Structured Interview of Personality Organization (STIPO), a semistructured interview designed for the dimensional assessment of identity, primitive defenses, and reality testing, the three primary content domains in the model of personality health and disorder elaborated by Kernberg (1984; Kernberg & Caligor, 2005). Results of this investigation, conducted in a clinical sample representing a broad range of personality pathology, indicate that identity and primitive defenses as operationalized in the STIPO are internally consistent and that interrater reliability for all 3 content domains is adequate. Validity findings suggest that the assessment of one's sense of self and significant others (Identity) is predictive of measures of positive and negative affect, whereas the maladaptive ways in which the subject uses his or her objects for purposes of regulating one's self experience (Primitive Defenses) is predictive of measures of aggression and personality disorder traits associated with cluster B personality disorders. We discuss implications of these findings in terms of the theory-driven and trait-based assessment of personality pathology. PMID:20013454

    Here, two studies seek to characterize a parsimonious common-denominator personality structure with optimal cross-cultural replicability. Personality differences are observed in all human populations and cultures, but lexicons for personality attributes contain so many distinctions that parsimony is lacking. Models stipulating the most important attributes have been formulated by experts or by empirical studies drawing on experience in a very limited range of cultures. Factor analyses of personality lexicons of nine languages of diverse provenance (Chinese, Korean, Filipino, Turkish, Greek, Polish, Hungarian, Maasai, and Senoufo) were examined, and their common structure was compared to that of several prominent models in psychology. A parsimonious bivariate model showed evidence of substantial convergence and ubiquity across cultures. Analyses involving key markers of these dimensions in English indicate that they are broad dimensions involving the overlapping content of the interpersonal circumplex, models of communion and agency, and morality/warmth and competence. These "Big Two" dimensions-Social Self-Regulation and Dynamism-provide a common-denominator model involving the two most crucial axes of personality variation, ubiquitous across cultures. The Big Two might serve as an umbrella model serving to link diverse theoretical models and associated research literatures. PMID:23301793

    With the Millennium Development Goals (MDGs) showing uneven progress, this review identifies possible limitations arising from the MDG framework itself rather than extrinsic issues. A multidisciplinary literature review was conducted with a focus on limitations in the formulation of the MDGs, their structure, content and implementation. Of 1837 MDG-related articles, 90 met criteria for analysis. Articles describe MDGs as being created by only a few stakeholders without adequate involvement by developing countries and overlooking development objectives previously agreed upon. Others claim MDGs are unachievable and simplistic, not adapted to national needs, do not specify accountable parties and reinforce vertical interventions. While MDGs have promoted increased health and well-being in many countries by recognising and deliberating on the possible constraints of the MDG framework, the post-2015 agenda may have even greater impact.

This was the main focus of the Dubai International Conference on Water Resources and Integrated Management in the Third Millennium in Dubai, United Arab Emirates, 2-6 February 2002. The invited forum attracted an eclectic mix of international thinkers from five continents. Presentations and discussions on hydrology policy/property rights, and management strategies focused mainly on problems of water supply, irrigation, and/or ecosystems.

    A broadband modem/channelizer test set developed by NASA Lewis Research Center is discussed. The test set is a fully programmable, bit-error-rate (BER) test set designed for broadband modem-only and multichannel demultiplexer/demodulator characterization. It is currently configured for testing a multichannel demultiplexer/demodulator and was developed for the Advanced Research and Projects Agency under a Technology Reinvestment Program Cooperative Agreement entitled 'Millennium: 21st Century Broadband Digital Telecommunications Technology.' The test set can easily be modified to provide testing of other modems and multichannel demultiplexer/demodulator systems and is available to industry for such testing.

    With the subtle but occasionally vital exception of vaccination-induced immunity to many of the major infectious diseases, no human today is other than virtually identical biologically to those who greeted the dawn of the Second Millennium, nearly 1000 years ago. Culturally, however, we of the West are quite highly evolved from our ancestors of a millennium ago, primarily due to the advent of means for communicating with ever smaller latencies and ever higher bandwidths over ever greater distances in space and time: printed documents have been supplemented in succession by telephony, radio, video and, just now, the first personal communications sets. Also, within a fraction of a human lifetime from the present moment, the first prosthesis for the human brain has appeared and just very recently has become quite ubiquitous: digital computing systems. We are hardly members of the same species, culturally speaking; people of 1000 years ago would be truly and utterly lost in our communications-intensive civilization, and even a highly educated person from those times would swear that a personal computer equipped with a wireless communications module was as at least a familiar, if not a golem. Conversely, a computer-using person from our own times somehow translated back to 1000 A.D. would likely find the profound isolation and the ``informational slowness`` of life then to be acutely intolerable, certainly to a far greater extent than would a citizen of the High Middle Ages translated back to Augustus Caesar`s Rome.

  2. The lexical approach to the study of personality structure: toward the identification of cross-culturally replicable dimensions of personality variation.

    The structure of personality variation is discussed from the perspective of the lexical approach, which is based on the examination of relations among personality-descriptive adjectives that are indigenous to various languages. The results of this approach--which reveal a cross-culturally replicated set of six dimensions--are described. Specifically, the obtained structure corresponds rather closely to the Five-Factor Model, but differs from that model in the nature of the Agreeableness and Emotionality/Neuroticism factors and also in the existence of a sixth factor known as Honesty-Humility. It is suggested that the emergence of this structure provides support for attempts to establish a cross-culturally generalizable structural model that could summarize normal and abnormal personality variation.

    The present research was conducted to map the hierarchical structure of youths' personality traits, to identify the foundational level of this structure, and to test whether the meanings of some youth personality dimensions shift with age. We addressed these issues by analyzing personality parent reports describing a cross-sectional sample of 16,000 children, adolescents, and young adults (ages 3 to 20). These parent reports were made using a broadband measure of youths' personal characteristics, the common-language California Child Q-Set. Analyses of the full sample and comparisons of 16 age groups supported three main conclusions. First, the hierarchical structure of youths' personality traits both resembles and differs from the adult personality hierarchy in important ways. Second, a set of six dimensions--Extraversion, Agreeableness, Conscientiousness, Neuroticism, Openness to Experience, and Activity--may constitute the foundational level of the youth personality hierarchy from middle childhood through adolescence. This "Little Six" structure represents a union of the most prominent personality and temperament dimensions. Third, the meanings of some youth personality dimensions (e.g., Activity, Conscientiousness) shift systematically with age. These findings advance our understanding of when and how personality structure develops during the first two decades of life. PMID:23734942

    Thames Water is working with the New Millennium Experience Company to provide a water recycling system for the Millennium Dome which will supply 500 m3/d of reclaimed water for WC and urinal flushing. The system will treat water from three sources: rainwater--from the Dome roof greywater--from handbasins in the toilet blocks groundwater--from beneath the Dome site The treatment technologies will range from "natural" reedbeds for the rainwater, to more sophisticated options, including biological aerated filters and membranes for the greywater and groundwater. Pilot scale trials were used to design the optimum configuration. In addition to the recycling system, water efficient devices will be installed in three of the core toilet blocks as part of a programme of research into the effectiveness of conservation measures. Data on water usage and customer behaviour will be collected via a comprehensive metering system. Information from the Dome project on the economics and efficiency of on-site recycling at large scale and data on water efficient devices, customer perception and behaviour will be of great value to the water industry. For Thames Water, the project provides vital input to the development of future water resource strategies. PMID:11436793

    Soil redistribution plays an important role in the transport of carbon and nutrients between terrestrial ecosystems. However, quantification of soil redistribution and its effects on the global biogeochemical cycles is currently unknown. This study aims at developing new tools and methods to represent soil redistribution on a global scale, and contribute to the quantification of anthropogenic disturbances to the biogeochemical cycles. We present a new large-scale coarse resolution sediment budget model that can simulate spatial patterns and long-term trends in soil redistribution in floodplains and on hillslope, resulting from external forces such as climate and land use change. First, we validated the model for the Rhine catchment using observed Holocene sediment storage data and observed scaling behavior between sediment storage and catchment area. Then, we applied the model on 20 large river catchments globally, using climate and land cover data from the Max Planck Institute Earth System Model (MPI-ESM) for the last millennium (850 - 2005AD). We show that the model can reproduce current observed sediment yields if uncertainty in the observations is taken into account. Furthermore, we find that the change in erosion rates during the last millennium resulted in a significant increase in sediment storage for different global catchments. We identify land use change as the main driver behind this change in sediment storage. Finally, catchments characteristics, such as area and slope, play an important role in buffering or amplifying the effect of land use and other external forces on the change in erosion and sediment storage.

    Hurricanes are a persistent socio-economic hazard for countries situated in and around the Main Development Region (MDR) of Atlantic tropical cyclones. Climate-model simulations have attributed their interdecadal variability to changes in solar and volcanic activity, Saharan dust flux, anthropogenic greenhouse gas and aerosol emissions and heat transport within the global ocean conveyor belt. However, the attribution of hurricane activity to specific forcing factors is hampered by the short observational record of Atlantic storms. Here, we present the Extended Hurricane Activity (EHA) index, the first empirical reconstruction of Atlantic tropical cyclone activity for the last millennium, derived from a high-resolution lake sediment geochemical record from Jamaica. The EHA correlates significantly with decadal changes in tropical Atlantic sea surface temperatures (SSTs; r = 0.68 1854-2008), the Accumulated Cyclone Energy index (ACE; r = 0.90 1851-2010), and two annually-resolved coral-based SST reconstructions (1773-2008) from within the MDR. Our results corroborate evidence for the increasing trend of hurricane activity during the Industrial Era; however, we show that contemporary activity has not exceeded the range of natural climate variability exhibited during the last millennium.

    Research on the factor structure of psychopathy has yielded mixed results, supporting anywhere from one to three factors. Additionally, most of this research has used all-male samples, and the possibility of structural invariance across gender has not been examined. Using a mixed-gender sample of 360 undergraduates, the factor structure of the Psychopathic Personality Inventory-Revised was examined using confirmatory factor analysis and multiple group analysis. One-, two-, and three-factor models were tested and compared with each other. When males and females were combined, none of the three models provided adequate fit to the data. Multiple group analyses revealed partial invariance across gender for all three models. Model comparison criteria supported use of both the one- and two-factor models, taking into account variable factor structure across gender. The importance of considering structural differences based on biological sex when assessing psychopathic traits is discussed. PMID:21490056

    The Millennium Villages Project (MVP), based at The Earth Institute at Columbia University, is a bottom-up, community led approach to show how villages in developing countries can get out of the poverty trap that afflicts more than a billion people worldwide. With well-targeted, practical inputs can help the community invest in a path leading to self-sustaining development. There are 80 Millennium Villages clustered in 10 countries throughout sub-Saharan Africa. MVP is an important development process for empowering communities to invest in a package of integrated interventions aiming to increase food production, improve access to safe water, health care, education and infrastructure. The process benefits from synergies of the integrated approach and relies on community leadership as empowered by proven technological inputs. MVP is committed to a science-based approach to assess and monitor the progress of the communities towards clear objectives; the Millennium Development Goals (MDGs) and to do so with mechanisms that are scalable and sustainable. This approach offers much more than simply collecting and analyzing data since the mechanism used for recording progress would provide a bridge over the divide which separates the haves and the have-nots (by facilitating the sharing of solutions from one community to another bidirectionally). By so doing, it allows people to enhance their own futures in a sustainable manner. Solutions found in one community are transferable to similar communities in other MVP villages. To achieve this goal, the MVP requires an information and communication system which can provide both necessary infrastructure for monitoring and evaluation, and tools for communicating among the villages, cities and countries. This system is called the Millennium Global Village-Net (MGV-Net). It takes advantage of the latest in open source software (OpenMRS), databases (MySQL), interface terminology, a centralized concept dictionary, and uses appropriate

    Acquiescence, or the tendency to respond to descriptions of conceptually distinct personality attributes with agreement/affirmation, constitutes a major challenge in personality assessment. The aim of this study was to shed light on cognitive ability as a potential source of individual differences in acquiescent responding. We hypothesized that respondents with lower cognitive ability exhibit stronger acquiescent response tendencies than respondents with higher cognitive ability and that this leads to problems in establishing the Big Five structure by means of principal component analyses (exploratory factor analysis was not applicable to these data) in the former group. Further, we hypothesized that after controlling for acquiescence by using mean-corrected instead of raw item scores, the Big Five structure holds even among respondents with lower cognitive ability. Analyses in a sample of 1,071 German adults aged 56 to 75 years using the Digit Symbol Substitution Test as a measure of cognitive ability and the BFI-10, a 10-item abbreviated version of the Big Five Inventory, as a measure of personality, corroborated these hypotheses. These findings suggest that lower cognitive ability and age-related declines in cognitive functioning more specifically are associated with higher acquiescence, which in turn leads to problems in establishing the Big Five structure among individuals with lower cognitive ability that should be addressed by controlling for acquiescence.

    On its opening day the London Millennium footbridge experienced unexpected large amplitude wobbling subsequent to the migration of pedestrians onto the bridge. Modeling the stepping of the pedestrians on the bridge as phase oscillators, we obtain a model for the combined dynamics of people and the bridge that is analytically tractable. It provides predictions for the phase dynamics of individual walkers and for the critical number of people for the onset of oscillations. Numerical simulations and analytical estimates reproduce the linear relation between pedestrian force and bridge velocity as observed in experiments. They allow prediction of the amplitude of bridge motion, the rate of relaxation to the synchronized state and the magnitude of the fluctuations due to a finite number of people. PMID:17358316

    It is well known that the history of battery electric vehicles (EVs) is a long one that covers a period in excess of one hundred years. It is also well known that, in their early days, these vehicles were capable of out-performing their contemporary internal combustion-engined (ICEV) equivalents in terms of speed and acceleration. Since those days, and indeed until quite recently, there has been a quite remarkable difference between the vast strides made in developing ICEVs in general and cars in particular, and the relatively small improvements made in the capabilities of EVs. It is now being argued that this must change and the purpose of this paper is to consider the extent to which it is practical to expect such a change, on a large scale, in the early part of the next millennium.

All three areas of radiation damage will be considered -- total dose, displacement effects, and single event effects. Each of these areas will be discussed in turn. First an overview and background will be provided on the historical understanding of the damage mechanism. Then there will be a discussion of recent enhancements to the understanding of those mechanisms and an up-to-date picture provided of the current state of knowledge. Next the potential impact of each of these damage mechanisms on devices in emerging technologies and how the mechanisms may be used to understand device performance will be described, with an emphasis on those likely to be of importance in the new millennium. Finally some additional thoughts will be presented on how device scaling expected into the next century may impact radiation hardness.

    Malaria, as a key disease of poverty, was singled out for special attention in the Millennium Project of 2000. Recent data suggest that malaria incidence and mortality are now declining all over the world. While these figures are cause for celebration, they must be interpreted carefully and with caution, particularly in relation to Africa. There are daunting challenges ahead for those working to achieve malaria eradication, not least of which is the poor quality of the data on which the work is based. In the absence of an affordable and fully effective vaccine, international funding for malaria control needs to be escalated still further. The money is essential to pay for universal access to a set of simple and proven interventions which would save the lives of millions of children over the next 15 years. PMID:25613970

    The paper gives the extension of the Schmidt-Kuhlmann method for reciprocating compressor pipeline systems having a tree-structure, consisting of receivers and pipes with an optional number of branchings. It gives a generalized algorithm which makes it possible to mechanize program constructing for the purpose of determining acoustic natural frequencies of complex structures, and it illustrates the use of personal computers—besides the actual numerical calculations—for automatic program-writing as well. The program developed is very useful in design practice for determining the effects caused by modification of the geometric dimensions, and it permits one to shift and avoid harmful acoustic resonances in preliminary planning.

    NASA's New Millennium Program is intended to validate advanced technologies in space and thus lower the risk for the first mission user. The New Millennium ST6 project has developed two advanced, experimental technologies for use on spacecraft of the future. These technologies are the Autonomous Sciencecraft Experiment and the Inertial Stellar Compass. These technologies will improve a spacecraft's ability to: 1) Make intelligent decisions on what information to gather and send back to the ground 2) Determine its own attitude and adjust its pointing. The significance of these technologies is in making the space missions less dependent on operators on the ground and shift the decision making to the spacecraft itself. Future missions using these technologies will be able to reduce the size of the ground crew lowering the mission cost or allowing to deploy resources on other aspects of the mission. Autonomous pointing and science gathering will also allow the spacecraft to react to ephemeral events that otherwise could not be detected in time due to long communication times from deep space. Sciencecraft technology involves feature and change detection, continuous planning technology, and robust execution. It is equipped with software that checks spacecraft performance and has resources to prevent errors. The Inertial Stellar Compass will enable a spacecraft to continuously determine its attitude and recover its orientation after a temporary malfunction or power loss. This is done by the "marriage" of a miniaturized star camera and gyro system. Compass technology uses an active pixel sensor in a star-tracking camera and a three-axis system of microelectromechanical gyros. These technologies will revolutionize future NASA spacecraft and allow mission resources to focus on science goals. This work done at JPL under contract with NASA

    In a year that will probably be remembered almost as much for books about the millennium as for the turn of 2000 A.D itself, Patrick Moore's Millennium Yearbook celebrates.....well, the wrong millennium! This thoroughly entertaining book - which is for everyone, not just astronomers - contains articles on King Alfred's chronological work, reviews of the new Star Catalogue by the Arab Al-Sufi and the latest edition of Ptolemy's Almagast. And foreshadowing the change to metric units by 1000 years, the book uses arabic numbers instead of Roman - but there is a conversion table if you have trouble with the idea of "zero" and prefer the older system.

    2002-07-01

    Three studies examined global self-esteem in relation to structural models of personality and affectivity. In every study, self-esteem was strongly negatively correlated with Neuroticism/Negative Affectivity and moderately to strongly related to Extraversion/Positive Affectivity. Additional findings, however, revealed that self-esteem is better viewed at the lower order level. For instance, global self-esteem correlated -.79 with the Depression facet of the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992) in Study 3. Moreover, confirmatory factor analyses produced very strong correlations between self-esteem and depression in both Study 2 (r = -.82) and Study 3 (r = -.86). Taken together, the data suggest that global self-esteem measures define one end of a bipolar continuum, with trait indicators of depression defining the other. PMID:12088125

    We examined properties of culture-level personality traits in ratings of targets (N = 5,109) aged 12 to 17 in 24 cultures. Aggregate scores were generalizable across gender, age, and relationship groups and showed convergence with culture-level scores from previous studies of self-reports and observer ratings of adults, but they were unrelated to national character stereotypes. Trait profiles also showed cross-study agreement within most cultures, eight of which had not previously been studied. Multidimensional scaling showed that Western and non-Western cultures clustered along a dimension related to Extraversion. A culture-level factor analysis replicated earlier findings of a broad Extraversion factor, but generally resembled the factor structure found in individuals. Continued analysis of aggregate personality scores is warranted. PMID:20573127

    The purposes of this research were to first examine the evidence regarding the factor structure of educational achievement tests in the context of two theoretical models of cognitive ability (psychometric g and mutualism) that have been proposed to explain this structure as well as the underlying processes that may be responsible for its emergence in dimensionality studies. Then, the factor structure underlying a sample of the standardized educational achievement tests used by California in its statewide school accountability program was compared to those emerging from a selection of behavioral and personality assessments. As expected, the educational achievement tests exhibited a strong and uniformly positive manifold resulting in greater unidimensionality as evidenced by a dominant general factor in bi-factor analysis then either the personality or behavioral assessments. The implications of these structural differences are discussed with respect to the two theoretical perspective as well as in the context of formative and summative educational inferences in particular, and the school accountability and reform movement in general.

  9. An alternative "description of personality": the big-five factor structure.

    PubMed

    Goldberg, L R

    1990-12-01

    In the 45 years since Cattell used English trait terms to begin the formulation of his "description of personality," a number of investigators have proposed an alternative structure based on 5 orthogonal factors. The generality of this 5-factor model is here demonstrated across unusually comprehensive sets of trait terms. In the first of 3 studies, 1,431 trait adjectives grouped into 75 clusters were analyzed; virtually identical structures emerged in 10 replications, each based on a different factor-analytic procedure. A 2nd study of 479 common terms grouped into 133 synonym clusters revealed the same structure in 2 samples of self-ratings and in 2 samples of peer ratings. None of the factors beyond the 5th generalized across the samples. In the 3rd study, analyses of 100 clusters derived from 339 trait terms suggest their potential utility as Big-Five markers in future studies. PMID:2283588

    This work presents a protein structure that has been designed purely for aesthetic reasons, symbolizing decades of coiled-coil research and praising its most fundamental model system, the GCN4 leucine zipper. The GCN4 leucine zipper is a highly stable coiled coil which can be tuned to adopt different oligomeric states via mutation of its core residues. For these reasons it is used in structural studies as a stabilizing fusion adaptor. On the occasion of the 50th birthday of Andrei N. Lupas, we used it to create the first personalized protein structure: we fused the sequence ANDREI-N-LVPAS in heptad register to trimeric GCN4 adaptors and determined its structure by X-ray crystallography. The structure demonstrates the robustness and versatility of GCN4 as a fusion adaptor. We learn how proline can be accommodated in trimeric coiled coils, and put the structure into the context of the other GCN4-fusion structures known to date. PMID:24486584

    The Minnesota Multiphasic Personality Inventory-2-Restructured Form (Ben-Porath & Tellegen, 2008 ) Restructured Clinical scales and Higher Order scales were linked to the Millon Clinical Multiaxial Inventory-III (Millon, Millon, Davis, & Grossman, 2009 ) personality disorder scales and clinical syndrome scales in a Flemish/Dutch sample of psychiatric inpatients and outpatients, substance abuse patients, correctional inmates, and forensic psychiatric patients (N = 968). Structural validity of psychopathology and personality disorders as conceptualized by both instruments was investigated by means of principal component analysis. Results reveal a higher order structure with 4 dimensions (internalizing disorders, externalizing disorders, paranoid ideation/thought disturbance, and pathological introversion) that parallels earlier research on pathological personality dimensions as well as research linking pathological personality traits with mental disorders. Theoretical and clinical implications are considered. PMID:22338624

    A new generation of sensor rich, massively distributed, autonomous systems are being developed that have the potential for profound social, environmental, and economic change. These include networked building energy systems, autonomous space probes, chemical plant control systems, satellite constellations for remote ecosystem monitoring, power grids, biosphere-like life support systems, and reconfigurable traffic systems, to highlight but a few. To achieve high performance, these immobile robots (or immobots) will need to develop sophisticated regulatory and immune systems that accurately and robustly control their complex internal functions. To accomplish this, immobots will exploit a vast nervous system of sensors to model themselves and their environment on a grand scale. They will use these models to dramatically reconfigure themselves in order to survive decades of autonomous operations. Achieving these large scale modeling and configuration tasks will require a tight coupling between the higher level coordination function provided by symbolic reasoning, and the lower level autonomic processes of adaptive estimation and control. To be economically viable they will need to be programmable purely through high level compositional models. Self modeling and self configuration, coordinating autonomic functions through symbolic reasoning, and compositional, model-based programming are the three key elements of a model-based autonomous systems architecture that is taking us into the New Millennium.

    The UK Millennium Cohort Study (MCS) is an observational, multidisciplinary cohort study that was set up to follow the lives of children born at the turn of the new century. The MCS is nationally representative and 18 552 families (18 827 children) were recruited to the cohort in the first sweep. There have currently been five main sweeps of data collection, at ages 9 months and 3, 5, 7 and 11 years. A further sweep of data collection is planned for age 14 years. A range of health-related data have been collected as well as measures concerning child development, cognitive ability and educational attainment. The data also include a wealth of information describing the social, economic and demographic characteristics of the cohort members and their families. In addition, the MCS data have been linked to administrative data resources including health records. The MCS provides a unique and valuable resource for the analysis of health outcomes and health inequalities. The MCS data are freely available to bona fide researchers under standard access conditions via the UK Data Service (http://ukdataservice.ac.uk) and the MCS website provides detailed information on the study (http://www.cls.ioe.ac.uk/mcs).

  15. Challenges of toxicology for the millennium.

    Wong, S H

    2000-02-01

    In meeting the challenges of toxicology, clinical and forensic toxicologists should expand their services and engage in research and development to meet changing needs. Expanding roles could potentially derive from the threat of terrorism, genotyping for interpretation of potential toxic drug interactions, and criminalistic testings. At the threshold of the next millennium, terrorism via weapons of mass destruction (WMD) has migrated from the war zones to civilian settings. These WMD may be in the form of nuclear, biological, and chemical devices (NBC). Recently, the possible use of chemical/biological weapons in the Middle East conflicts, the use of sarin in a Tokyo subway station, and the unregulated availability of nuclear fuel in some countries all have heightened the potential for international and domestic NBC. In preparation for NBC, both government and civilians in major American cities have been trained for safe handling of patients and casualties. Forensic and clinical toxicologists should be knowledgeable about the clinical pharmacology, safe samples processing, and possible screening and/or analysis of samples exposed to or containing: vesicants; cyanide; and nerve, riot control, and pulmonary agents. These samples may be transported for further analysis and confirmed by designated central laboratories. In criminal/correctional settings, toxicologists should engage in quality assurance and consultation with attorneys, judges, and correctional professionals. With the emergence of pharmacogenetics, genotyping may enhance rational drug therapy for enhanced patient care, and may explain adverse or fatal drug reactions in postmortem analysis. PMID:10688259

    The "Photochemical Phenomenology Model for the New Millennium" project tackles the issue of reengineering and extension of validated physics-based modeling capabilities ("legacy" computer codes) to application-oriented software for use in science and science-support activities. While the design and architecture layouts are in terms of general particle distributions involved in scattering, impact, and reactive interactions, initial Photochemical Phenomenology Modeling Tool (PPMT) implementations are aimed at construction and evaluation of photochemical transport models with rapid execution for use in remote sensing data analysis activities in distributed systems. Current focus is on the Composite Infrared Spectrometer (CIRS) data acquired during the CASSINI flyby of Jupiter. Overall, the project has stayed on the development track outlined in the Year 1 annual report and most Year 2 goals have been met. The issues that have required the most attention are: implementation of the core photochemistry algorithms; implementation of a functional Java Graphical User Interface; completion of a functional CORBA Component Model framework; and assessment of performance issues. Specific accomplishments and the difficulties encountered are summarized in this report. Work to be carried out in the next year center on: completion of testing of the initial operational implementation; its application to analysis of the CASSINI/CIRS Jovian flyby data; extension of the PPMT to incorporate additional phenomenology algorithms; and delivery of a mature operational implementation.

    The joint likelihood of observable cluster signals reflects the astrophysical evolution of the coupled baryonic and dark matter components in massive halos, and its knowledge will enhance cosmological parameter constraints in the coming era of large, multiwavelength cluster surveys. We present a computational study of intrinsic covariance in cluster properties using halo populations derived from Millennium Gas Simulations (MGS). The MGS are re-simulations of the original 500 h -1 Mpc Millennium Simulation performed with gas dynamics under two different physical treatments: shock heating driven by gravity only (GO) and a second treatment with cooling and preheating (PH). We examine relationships among structural properties and observable X-ray and Sunyaev-Zel'dovich (SZ) signals for samples of thousands of halos with M 200 >= 5 × 1013 h -1 M sun and z < 2. While the X-ray scaling behavior of PH model halos at low redshift offers a good match to local clusters, the model exhibits non-standard features testable with larger surveys, including weakly running slopes in hot gas observable-mass relations and ~10% departures from self-similar redshift evolution for 1014 h -1 M sun halos at redshift z ~ 1. We find that the form of the joint likelihood of signal pairs is generally well described by a multivariate, log-normal distribution, especially in the PH case which exhibits less halo substructure than the GO model. At fixed mass and epoch, joint deviations of signal pairs display mainly positive correlations, especially the thermal SZ effect paired with either hot gas fraction (r = 0.88/0.69 for PH/GO at z = 0) or X-ray temperature (r = 0.62/0.83). The levels of variance in X-ray luminosity, temperature, and gas mass fraction are sensitive to the physical treatment, but offsetting shifts in the latter two measures maintain a fixed 12% scatter in the integrated SZ signal under both gas treatments. We discuss halo mass selection by signal pairs, and find a minimum mass

    This short review, with a bit of historical aspect and a strong personal bias and emphases on open questions, is focusing on the (macro-)organization and structural-functional flexibilities of the photosynthetic apparatus of oxygenic photosynthetic organisms at different levels of the structural complexity-selected problems that have attracted most my attention in the past years and decades. These include (i) the anisotropic organization of the pigment-protein complexes and photosynthetic membranes-a basic organizing principle of living matter, which can, and probably should be adopted to intelligent materials; (ii) the organization of protein complexes into chiral macrodomains, large self-assembling highly organized but structurally flexible entities with unique spectroscopic fingerprints-structures, where, important, high-level regulatory functions appear to 'reside'; (iii) a novel, dissipation-assisted mechanism of structural changes, based on a thermo-optic effect: ultrafast thermal transients in the close vicinity of dissipation of unused excitation energy, which is capable of inducing elementary structural changes; it makes plants capable of responding to excess excitation with reaction rates proportional to the overexcitation above the light-saturation of photosynthesis; (iv) the 3D ultrastructure of the granum-stroma thylakoid membrane assembly and other multilamellar membrane systems, and their remodelings-associated with regulatory mechanisms; (v) the molecular organization and structural-functional plasticity of the main light-harvesting complex of plants, in relation to their crystal structure and different in vivo and in vitro states; and (vi) the enigmatic role of non-bilayer lipids and lipid phases in the bilayer thylakoid membrane-warranting its high protein content and contributing to its structural flexibility.

    The vast majority of empirical research in the behavioral sciences is based on the analysis of between-person variation. In contrast, much of applied psychology is concerned with the analysis of variation within individuals. Furthermore, the mechanisms specified by psychological theories generally operate within, rather than across, individuals. This disconnect between research practice, applied demands, and psychological theories constitutes a major threat to the conceptual integrity of the field. Following groundbreaking earlier work, we propose a conceptual framework that distinguishes within-person (WP) and between-person (BP) sources of variation in psychological constructs. By simultaneously considering both sources of variation, it is shown how to identify possible reasons for nonequivalence of BP and WP structures as well as establishing areas of convergence. For this purpose, we first introduce the concept of conditional equivalence as a way to study partial structural equivalence of BP and WP structures in the presence of unconditional nonequivalence. Second, we demonstrate the construction of likelihood planes to explore the causes of structural nonequivalence. Third, we examine 4 common causes for unconditional nonequivalence-autoregression, subgroup differences, linear trends, and cyclic trends-and demonstrate how to account for them. Fourth, we provide an empirical example on BP and WP differences in attentiveness. PMID:26735189

    Personal health records (PHRs) provide patient-centric healthcare by making health records accessible to patients. In China, it is very difficult for individuals to access electronic health records. Instead, individuals can easily obtain the printed copies of their own medical records, such as prescriptions and lab test reports, from hospitals. In this paper, we propose a practical approach to extract structured data from printed medical records photographed by mobile phones. An optical character recognition (OCR) pipeline is performed to recognize text in a document photo, which addresses the problems of low image quality and content complexity by image pre-processing and multiple OCR engine synthesis. A series of annotation algorithms that support flexible layouts are then used to identify the document type, entities of interest, and entity correlations, from which a structured PHR document is built. The proposed approach was applied to real world medical records to demonstrate the effectiveness and applicability. PMID:26958219

    This study addressed whether personality ratings using a 43 adjective questionnaire based on the Five-Factor Model generalized from a sample of 202 zoo-housed chimpanzees to a sample of 175 chimpanzees housed in Yerkes National Primate Research Center. Mean interrater reliabilities of adjectival ratings were lower for the chimpanzees housed in Yerkes. In addition, rank order of the interrater reliabilities of items differed between settings. To compare factor structure, we first examined whether we could replicate the original six factor structure found in an earlier study of 100 zoo chimpanzees using principal factors analysis in the Yerkes sample and 102 new zoo chimpanzees. The dominance, extraversion, conscientiousness, and agreeableness factors were clearly replicated in the Yerkes sample and the 102 new zoo chimpanzees. The Neuroticism and Openness factors did not replicate in the Yerkes sample, but they also did not replicate in the new zoo chimpanzees. These findings suggest the need to sample more adjectives representing neuroticism and openness in future versions of the questionnaire. We next sought to determine whether factor structure, as determined by principal components analysis, remained invariant across the two settings. This analysis revealed dominance, extraversion, conscientiousness, and agreeableness factors in both settings and a high level of congruence between the zoo and Yerkes samples for these factors. Finally, we tested whether factor scores in the two samples were similarly related to age and sex. With the exception of differences in age effects for dominance and agreeableness, age, and sex effects were consistent across samples. These findings suggest that, whereas there may be differences in the ease with which ratings are made, personality structure, and development are largely consistent across widely differing settings.

    Much debate in schizotypal research has centred on the factor structure of the Schizotypal Personality Questionnaire (SPQ), with research variously showing higher-order dimensionality consisting of two to seven dimensions. In addition, cross-cultural support for the stability of those factors remains limited. Here, we examined the factor structure of the SPQ among British and Trinidadian adults. Participants from a White British subsample (n = 351) resident in the UK and from an African Caribbean subsample (n = 284) resident in Trinidad completed the SPQ. The higher-order factor structure of the SPQ was analysed through confirmatory factor analysis, followed by multiple-group analysis for the model of best fit. Between-group differences for sex and ethnicity were investigated using multivariate analysis of variance in relation to the higher-order domains. The model of best-fit was the four-factor structure, which demonstrated measurement invariance across groups. Additionally, these data had an adequate fit for two alternative models: (a) 3-factor and (b) modified 4-factor model. The British subsample had significantly higher scores across all domains than the Trinidadian group, and men scored significantly higher on the disorganised domain than women. The four-factor structure received confirmatory support and, importantly, support for use with populations varying in ethnicity and culture. PMID:25699263

    There are few brief measures of identity disturbance for use in clinical practice that have been subject to any cross-cultural validation. This study investigated the construct validity of the Personality Structure Questionnaire (PSQ) in Italian clinical (N = 237) and community (N = 296) samples. Confirmatory factor analysis was conducted to investigate the internal structure of the PSQ. A 3-factor structure (i.e., differing self-states, mood variability, and behavioral loss of control) including a second-order factor provided the best fit to the data. This structure was demonstrated to be invariant across sex and clinical diagnosis, with clinical diagnosis significantly predicting increased PSQ scores. A global PSQ score of between 26 and 28 was found to be an appropriate cutoff for assisting in diagnostic processes. The clinical implication of the study is that quantitative assessment of identity disturbance can be rapidly achieved via the PSQ, usefully supplementing necessary diagnostic and formulation work.

    Smith College has recently established the Louise B. and Edmund J. Kahn Liberal Arts Institute to foster interdisciplinary scholarship among the faculty. In the 1999-2000 academic year, the Kahn Institute is sponsoring a project entitled "Star Messenger: Galileo at the Millennium." The project will explore the impact of the astronomical discoveries of Galileo and his contemporaries on the Renaissance world-view and also use Galileo's experience as a lens for examining scientific and cultural developments at the symbolic juncture represented by the year 2000. Seven faculty fellows and 10-12 student fellows will participate in a year-long colloquium pursuing these themes, aided by the participation of some five Visiting Fellows. The inaugural public event will be a symposium on the historical Galileo, with presentation by three noted scholars, each of whom will return to campus for a second meeting with the Kahn colloquium. Additional events will include an exhibit of prints, artifacts, and rare books related to Galileo and his time, an early music concert featuring music composed by Galileo's father, and a series of other events sponsored by diverse departments and programs, all related to the broad themes of the Galileo project. The culminating events will be the premiere of a new music theater work, which will encapsulate the insights of the colloquium about human reactions to novel insights about the world, and a symposium presenting the research results of faculty and student fellows. The symposium will feature a capstone lecture by an visionary scholar projecting the implication of historical and contemporary trends into the future.

    New Space Industries For the Next Millennium is a final report of the findings from the New Space Industries Workshop held in Washington, DC, in February 1998. The primary purpose of this workshop was to identify what must be done to develop new markets, and to generate plans, milestones and new organizational relationships designed to facilitate the goal of space development. This document provides a summary report on the results of that workshop and is not intended as a statement of NASA or government policy. Previous studies had shown great potential for the development of new markets in space (e.g., travel and entertainment, space solar power, satellite and space transfer services, research and development in space, space manufacturing, and space resources), and a great need for coordination and formation of infrastructures (e.g., space transportation, space business parks, and space utilities), to facilitate the growth of new space businesses. The New Space Industries Workshop brought together government, academia, and industry participants from several previous studies and other professionals interested in the development of space for commercial purposes. Their participation provided input into the role of government and industry in space development as well as the technology needs that will enable space development. The opening of the frontier of space, not just to government missions but to private individuals and commercial business, is a challenge of overarching importance. It is our hope that the workshop and this final report continue in earnest the process of identifying and overcoming the barriers to large-scale public access and development of space in the early years of the next century.

    In today's modern, industrialized and affluent countries, like Japan and Australia, better living conditions and hygiene, plentiful nutritious food and rapid advances in biology and medical technologies have helped to bring about dramatic improvements in child health. The previous heavy burdens of infections and undernutrition have been eliminated or can now be controlled or effectively treated. In these countries, child health standards are higher than ever and expectation of life at birth is much higher than in the past. Some of the technological advances that have helped bring about this transformation are immunization, antimicrobial therapy, successful treatment of childhood leukemias, transplantation of vital organs and implementation of genetic diagnosis and gene therapy. The use of genetically modified foods and the prospects for cloning of humans are areas of intense interest and controversy. However, these advances have their disadvantages (e.g. antibiotic-induced drug resistance). Urbanization has encouraged the 'westernization' of dietary patterns and the long-term 'lifestyle diseases' that can follow in adults. Accidents, violence and drug abuse are major problems in many parts of the world. Changes in attitudes to sexuality and the spread of HIV/AIDS is another major problem, especially in Africa and Asia. Environmental pollution and the degradation of agricultural lands, rivers and seas are also important. Ironically, standards of child health and the prospects for long life in countries like Japan are better than ever before, but social and environmental changes are presenting children and their carers with new and unanswered challenges as we enter the 21 st century and the new millennium.

    This paper illustrates the use of composite first person narrative interpretive methods, as described by Todres, across a range of phenomena. This methodology introduces texture into the presently understood structures of phenomena and thereby creates new understandings of the phenomenon, bringing about a form of understanding that is relationally alive that contributes to improved caring practices. The method is influenced by the work of Gendlin, Heidegger, van Manen, Gadamer, and Merleau-Ponty. The method's applicability to different research topics is demonstrated through the composite narratives of nursing students learning nursing practice in an accelerated and condensed program, obese female adolescents attempting weight control, chronically ill male parolees, and midlife women experiencing distress during menopause. Within current research, these four phenomena have been predominantly described and understood through quantified articulations that give the reader a structural understanding of the phenomena, but the more embodied or “contextual” human qualities of the phenomena are often not visible. The “what is it like” or the “unsaid” aspects of such human phenomena are not clear to the reader when proxies are used to “account for” a variety of situated conditions. This novel method is employed to re-present narrative data and findings from research through first person accounts that blend the voices of the participants with those of the researcher, emphasizing the connectedness, the “we” among all participants, researchers, and listeners. These re-presentations allow readers to develop more embodied understandings of both the texture and structure of each of the phenomena and illustrate the use of the composite account as a way for researchers to better understand and convey the wholeness of the experience of any phenomenon under inquiry.

    We examine the correlational structure of the personality disorder (PD) scales from the MCMI-III (Millon, 1994) among 614 college students. The correlation matrix from our nonclinical sample was highly similar to the clinical sample matrices reported by Millon (1994). Further analyses revealed that the correlation matrices from a variety of MCMI data sets are generally similar to one another, but are only moderately similar to PD correlation matrices based on other assessment techniques. PD correlation matrices based on different assessment techniques are generally not very similar to one another. Two-, 3-, and 4-factor solutions for the MCMI-III PD scales are reported and provide a framework for integrating apparently conflicting findings from previous work. The 4-factor solution was most meaningful and was consistent with the 5-factor model of PD. PMID:9501485

    2016-08-01

    Person-oriented approaches to clinical research aim to uncover subgroups of patients with different patterns of clinically relevant variables. Such approaches, however, are not yet widely employed in clinical neuroimaging research. This paper demonstrates an accessible approach to person-oriented research using model-based clustering in high-dimensional structural neuroimaging data. Cortical thickness measurements for 369 older adults (182 women, 187 men) were obtained from the Alzheimer's Disease Neuroimaging Initiative. Model-based cluster analysis was performed on these imaging variables and then validated using variables that were not used in the clustering process. Variable selection identified two specific regions that contributed to cluster formation: the left and right entorhinal cortices. Two subgroups were uncovered: a "typical" cluster with higher entorhinal thickness (M=3.59mm, 95% confidence interval=3.57, 3.62), and an "atypical" cluster with relatively lower thickness (M=2.84mm, 95% confidence interval=2.75, 2.92). Members of the atypical cluster also had lower hippocampal volumes, memory scores, and executive function scores, and were also more likely to be clinically classified as cognitively impaired. These findings demonstrate the utility of model-based clustering of structural neuroimaging data in studies of ageing. The role of the entorhinal cortices in cluster formation is consistent with the known pathological substrate of Alzheimer's disease. The entorhinal cortices are implicated in the early genesis of the disease and atrophy of these regions is strongly associated with the cognitive phenotype. Overall, this approach can be readily applied to future neuroimaging investigations. PMID:27056675

    For many decades the practice of radiology grew slowly in America and was largely a secondary function under the control of hospitals. In more recent times it has vastly expanded its array of diagnostic, interventional, and therapeutic abilities. There is increasing consumer logic for direct access. Motivations have grown to create large independent entities with broadly diverse capabilities in order to succeed in the new millennium. Most regional markets are evolving rapidly in terms of managed care penetration, health system formation, physician practice consolidation and aggressive purchaser behavior by employers and consumers. To understand the enormity of healthcare evolution, it is useful to look at the industry's paradigm shifts in recent decades. Virtually every aspect of organizational infrastructure, delivery approaches, and the business environment has evolved markedly during the past fifty years. These changes will accelerate. To succeed financially, radiology groups must strengthen their market positions, technical capabilities, continuums of care and geographic dominance. Equally important is the wisdom of diversifying incomes into related services and businesses that provide additional related revenues. Key factors for successful development include facility market growth, full coverage of managed care contracts, high efficiency and aggressive diversification. A fully evolved system generates significant revenues and profitability by protecting and strengthening its financial position in this environment. That is accomplished through the development of strategically located radiology groups, aggressive alliances with medical practices in allied disciplines, and managed radiology departments and facilities for partner health systems. Organizational success ultimately depends on the ability to accept capitated payments under risk-bearing arrangements. The strategic business plan should be organized with the appropriate levels of detail needed to

    NASA's New Millennium Program (NMP) is formulating the Space Technology 8 (ST8) subsystem demonstration mission, which will qualify, on a single spacecraft provided by Orbital Sciences Corporation, four technologies: Thermal Loop, a miniature loop heat pipe system with multiple evaporators; SAILMAST, a gossamer mast; Ultraflex 175, an ultra-lightweight, deployable solar array; and Dependable Multiprocessor, a fault-tolerant COTS processor for onboard science computing. These technologies have been identified by NMP, with input from the space science community, as necessary to enable future NASA space science missions. Examples of previous enabling technologies demonstrated by NMP are the ion engines on Deep Space 1 and the Autonomous Sciencecraft Experiment demonstrated by ST6. The Thermal Loop, provided by NASA's Goddard Space Flight Center will demonstrate that a loop heat pipe with multiple evaporators and condensers can transport large heat loads over long distances without external pumping. It is expected that this technology will enable more precise temperature control decreasing the mass, power, and volume of small remote sensing and surface-based spacecraft. The SAILMAST experiment is a deployable gossamer mast technology, which will validate its load-carrying characteristics by correlating in-flight measurements with analytical predictions. It will enable a new class of missions, which employ solar sail propulsion technology. The Ultraflex 175 will demonstrate the next generation in ultra-lightweight fan-folded flexible solar arrays, providing ultra-high specific power (170-220 W/kg BOL), ultracompact stowage volume (>33 W/m3), and high deployed stiffness. The result is less mass and volume needed for power generation on future spacecraft. The Dependable Multiprocessor will integrate commercial-off-the-shelf (COTS) processing components and fault-tolerant control algorithms to provide an adaptable, high-performance, on-board science processing platform.

    Sanger, A C

    1998-01-01

    In order to take the fight for reproductive rights into the next millennium, women in the US must be reminded of what life was like for women when contraception and abortion were illegal, and the silent majority of women who accept that abortion is a private decision must be marshalled to express their views politically. In the US, abortion was allowed until the mid- to late-1800s when Protestant leaders feared that Protestant births were being outnumbered by births to Irish Roman Catholic immigrants. There was only minimal organized opposition to abortion during the period when it was illegal and millions of women were dying as a result. An estimated 30,000 women died each year of illegal abortion in the US, and by the 1960s, illegal abortion was the greatest killer of women of reproductive age. Organized medicine, which witnessed these tragedies, never rallied to assure women quality reproductive health care. In fact, one of the first projects of the American Medical Association (AMA) was an anti-abortion campaign designed to put competitors out of business. The AMA waited until 1937 to endorse contraception and until the late 1960s to make efforts to legalize abortion. In 1997, the AMA again abandoned women by supporting the ban on late-term abortions. Pro-choice forces should prioritize the promotion of technological advances that will allow women to control conception and abortion. The means of achieving medical abortion and emergency contraception should be available in every physician's office and should be covered by every health insurance scheme. Reproductive health advocates must also work to inspire honesty about sex and sexuality in our sexually-obsessed, sexually-repressed society. Sex education in Denmark has nearly obliterated adolescent pregnancy and led to an 80% decline in the abortion rate over 30 years. In the US, nearly half of women have an abortion, and anti-abortion advocates should face the reality that their wives, daughters, mothers, and

  20. Teaching bioethics in the new millennium: holding theories accountable to actual practices and real people.

    PubMed

    Tong, Rosemarie

    2002-08-01

    Teaching bioethics in the new millennium requires its practitioners to confront a wide area of methodological alternatives. This essay chronicles the author's journey from the principlism of Beauchamp and Childress, through narrative and postmodern bioethics, to a complex feminist critique of postmodern bioethics that emphasizes functional human capabilities and the creation of structures that can facilitate free discussion of those capabilities and how best to realize them. Teaching bioethics concerns not only the acknowledgement of differences but also reminding ourselves of our samenesses. Sustained Habermasian democratic conversations might help us to escape the narrow confines of a postmodern bioethics of moral strangers for a richer world of moral friends. PMID:12221502

    Genome-Wide Association Studies (GWAS), whole genome sequencing, and high-throughput omics techniques have generated vast amounts of genotypic and molecular phenotypic data. However, these data have not yet been fully explored to improve the effectiveness and efficiency of drug discovery, which continues along a one-drug-one-target-one-disease paradigm. As a partial consequence, both the cost to launch a new drug and the attrition rate are increasing. Systems pharmacology and pharmacogenomics are emerging to exploit the available data and potentially reverse this trend, but, as we argue here, more is needed. To understand the impact of genetic, epigenetic, and environmental factors on drug action, we must study the structural energetics and dynamics of molecular interactions in the context of the whole human genome and interactome. Such an approach requires an integrative modeling framework for drug action that leverages advances in data-driven statistical modeling and mechanism-based multiscale modeling and transforms heterogeneous data from GWAS, high-throughput sequencing, structural genomics, functional genomics, and chemical genomics into unified knowledge. This is not a small task, but, as reviewed here, progress is being made towards the final goal of personalized medicines for the treatment of complex diseases. PMID:24830652

  7. Identifying with fictive characters: structural brain correlates of the personality trait ‘fantasy’

    PubMed Central

    Hänggi, Jürgen; Jancke, Lutz

    2014-01-01

    The perception of oneself as absorbed in the thoughts, feelings and happenings of a fictive character (e.g. in a novel or film) as if the character’s experiences were one’s own is referred to as identification. We investigated whether individual variation in the personality trait of identification is associated with individual variation in the structure of specific brain regions, using surface and volume-based morphometry. The hypothesized regions of interest were selected on the basis of their functional role in subserving the cognitive processing domains considered important for identification (i.e. mental imagery, empathy, theory of mind and merging) and for the immersive experience called ‘presence’. Controlling for age, sex, whole-brain volume and other traits, identification covaried significantly with the left hippocampal volume, cortical thickness in the right anterior insula and the left dorsal medial prefrontal cortex, and with gray matter volume in the dorsolateral prefrontal cortex. These findings show that trait identification is associated with structural variation in specific brain regions. The findings are discussed in relation to the potential functional contribution of these regions to identification. PMID:24464847

    A wealth of research has underscored the strong relationship between PCL-R scores and recidivism. However, mounting criticism cites the PCL-R's cumbersome administration procedures and failure to adequately measure core features associated with the construct of psychopathy (Skeem, Polaschek, Patrick, & Lilienfeld, 2011). In light of these concerns, this study examined the PPI and the PPI-R, which were designed to measure core personality features associated with psychopathy (Lilienfeld & Andrews, 1996; Lilienfeld & Widows, 2005). Study one examined the PPI relative to the PCL-R and examined its factor structure. The instruments shared few significant correlations and neither the PCL-R nor the PPI significantly predicted recidivism. Study two examined the PPI-R relative to the PCL-R, the PPI, both history of violence and future criminal activity and measure of related constructs. The PPI-R was significantly correlated with measures of empathy and criminal thinking and the factors were related to a history of violence and predicted future violent criminal behavior.

  10. The Recaptured Scale Technique: A Method for Testing the Structural Robustness of Personality Scales.

    Tellegen and Waller advocated a complex and time-consuming scale construction method that they called "exploratory test construction." Scales that are constructed by this method-such as the Multidimensional Personality Questionnaire (MPQ)-are presumed to be more "psychologically coherent" and "robust" than scales constructed by other means. Using a novel procedure that we call the "recaptured scale technique," we tested this conjecture by conducting a megafactor analysis on data from the 411 adult participants of the Minnesota Study of Twins Reared Apart who completed the MPQ, the MMPI, and the CPI. We extracted and obliquely rotated 21 factors from a matrix of gender-corrected tetrachoric correlations for the 1,102 nonredundant items of the three omnibus inventories. Robustness of the 11 MPQ scales was assessed by the degree to which these factors recaptured the MPQ item groupings. Our results showed that nine factors were clearly recognizable as MPQ scales and two additional factors represented a bifurcation of an MPQ scale. A higher-order factor analysis of all 21 factor scales yielded five factors that clearly resembled the Big Five. Our results provide strong support for (a) the method of exploratory test construction, (b) the structural robustness of most MPQ scales, and PMID:27191377

    In Ref. [1] we proposed an analogy between the thermal Boltzmann-Gibbs probability distribution of energy in physics and the probability distribution of money in economics in statistical equilibrium. In Ref. [2] we find that the probability distribution of personal income in the USA has a well-defined two-class structure. The majority of population (97-99%) belongs to the lower class characterized by the exponential Boltzmann-Gibbs (``thermal'') distribution, whereas the upper class (1-3% of population) has a Pareto power-law (``superthermal'') distribution. By analyzing the income data for 1983--2001 from IRS, we show that the ``thermal'' part is stationary in time, save for a gradual increase of the effective temperature, whereas the nonequilibrium ``superthermal'' tail swells and shrinks following the stock market. We discuss the concept of equilibrium inequality in a society, based on the principle of maximal entropy, and quantitatively show that it applies to the majority of the US population. [] [1] A.

    Current DSM-based instruments for personality disorders (PDs) limit the investigation of the course and outcome of treatment of these disorders. This study examined the validity of the Shedler-Westen Assessment Procedure-200 (SWAP-200) and the Structured Clinical Interview for DSM-IV Axis II PD (SCID-II) in a sample of forensic PD patients. Results based on 66 participants indicated that the SWAP-200 Q-factors reduced the frequency of diagnostic comorbidity of PD categories by half compared with the SCID-II. Only the SWAP-200's Antisocial PD category showed good convergent and discriminant validity with respect to other instruments describing aspects of PD. The validity of the cutoff score for severe antisocial PD was confirmed, and this category predicted severe incidents in the hospital at 1 year of follow-up. A violence risk scale was constructed, which differentiated violent and nonviolent offenders. The results support the validity of the SWAP-200 and its potential clinical utility with forensic PD patients. PMID:24511901

    Personal Web usage (PWU) represents a tension between employers and employees as employers generally regard employees' PWU as negative and employees see many PWU behaviors as acceptable. Employers attempt to limit PWU primarily through electronic monitoring and Internet usage policies. Employees, however, find PWU not only permissible, but also useful and rationalize these workplace behaviors. While researchers identified many PWU behaviors, the underlying structure of the phenomenon is not clearly understood. In this article, we offer a comprehensive new definition of PWU, and develop an empirically grounded classification of PWU framed by psychological contract theory and based on two studies. Using multidimensional scaling techniques and cluster analysis, we identified four clusters of PWU behaviors-work/family, hedonic, self-development, and citizenship. The results provide information as to what constitutes the domain of PWU, and how various usages are related to one another via the dimensions of individual and organizational benefits. We offer directions for future work and suggest how our work might be useful to practitioners. PMID:21728817

    There is no agreement on the pluri-decadal expression of El Niño-Southern Oscillation (ENSO) in the Pacific over the last millennium. Marine records from the Peruvian margin indicate humid conditions (El Niño-like mean conditions) over the Little Ice Age, while precipitation records from the eastern equatorial Pacific infer arid conditions (La Niña-like mean conditions) for the same period. We here studied diatom assemblages, nitrogen isotopes, and major and minor elements at the lamination level in three laminated trigger cores located between 11°S and 15°S on the Peruvian shelf within the oxygen minimum zone (OMZ) to reconstruct precipitation and ocean productivity at the multiannual to multidecadal timescales over the last millennium. We respected the sediment structure, thus providing the first records of the mean climatic conditions at the origin of the lamination deposition, which ones represent several years. Light laminations were deposited under productive and dry conditions, indicative of La Niña-like mean conditions in the system, while dark laminations were deposited under non-productive and humid conditions, representative of El Niño-like mean conditions. La Niña-like mean conditions were predominant during the Medieval Warm Period (MWP; 1000-600 years BP) and Current Warm Period (CWP; 150 years BP to present), while El Niño-like mean conditions prevailed over the Little Ice Age (LIA; 600-150 years BP). We provide evidence for persistent multidecadal variations in productivity over the last millennium, which were disconnected from the mean climate state. Multidecadal variability has been stronger over the last 450 years concomitantly to increased variability in the NAO index. Two intervals of strong multidecadal variability were also observed over the MWP, congruent to decreased solar irradiance and increased volcanic activity.

    The goal of human genome re-sequencing is obtaining an accurate assembly of an individual's genome. Recently, there has been great excitement in the development of many technologies for this (e.g. medium and short read sequencing from companies such as 454 and SOLiD, and high-density oligo-arrays from Affymetrix and NimbelGen), with even more expected to appear. The costs and sensitivities of these technologies differ considerably from each other. As an important goal of personal genomics is to reduce the cost of re-sequencing to an affordable point, it is worthwhile to consider optimally integrating technologies. Here, we build a simulation toolbox that will help us optimally combine different technologies for genome re-sequencing, especially in reconstructing large structural variants (SVs). SV reconstruction is considered the most challenging step in human genome re-sequencing. (It is sometimes even harder than de novo assembly of small genomes because of the duplications and repetitive sequences in the human genome.) To this end, we formulate canonical problems that are representative of issues in reconstruction and are of small enough scale to be computationally tractable and simulatable. Using semi-realistic simulations, we show how we can combine different technologies to optimally solve the assembly at low cost. With mapability maps, our simulations efficiently handle the inhomogeneous repeat-containing structure of the human genome and the computational complexity of practical assembly algorithms. They quantitatively show how combining different read lengths is more cost-effective than using one length, how an optimal mixed sequencing strategy for reconstructing large novel SVs usually also gives accurate detection of SNPs/indels, how paired-end reads can improve reconstruction efficiency, and how adding in arrays is more efficient than just sequencing for disentangling some complex SVs. Our strategy should facilitate the sequencing of human genomes at

    Posttraumatic stress disorder (PTSD) is associated with aggressive behavior in veterans, and difficulty controlling aggressive urges has been identified as a primary postdeployment readjustment concern. Yet only a fraction of veterans with PTSD commit violent acts. The goals of this study were to (1) examine the higher-order factor structure of Personality Assessment Inventory (PAI) scales in a sample of U.S. military veterans seeking treatment for PTSD; and (2) to evaluate the incremental validity of higher-order latent factors of the PAI over PTSD symptom severity in modeling aggression. The study sample included male U.S. Vietnam (n = 433) and Iraq/Afghanistan (n = 165) veterans who were seeking treatment for PTSD at an outpatient Veterans Affairs (VA) clinic. Measures included the Clinician Administered PTSD Scale, the PAI, and the Conflict Tactics Scale. The sample was randomly split into two equal subsamples (n’s = 299) to allow for cross-validation of statistically derived factors. Parallel analysis, variable clustering analysis, and confirmatory factor analyses were used to evaluate the factor structure, and regression was used to examine the association of factor scores with self-reports of aggression over the past year. Three factors were identified: internalizing, externalizing, and substance abuse. Externalizing explained unique variance in aggression beyond PTSD symptom severity and demographic factors, while internalizing and substance abuse did not. Service era was unrelated to reports of aggression. The constructs of internalizing versus externalizing dimensions of PTSD may have utility in identifying characteristics of combat veterans in the greatest need of treatment to help manage aggressive urges.

    A series of surveys were carried out to characterize the physical and biological parameters of the Millennium Atoll lagoon during a research expedition in April of 2009. Millennium is a remote coral atoll in the Central Pacific belonging to the Republic of Kiribati, and a member of the Southern Line Islands chain. The atoll is among the few remaining coral reef ecosystems that are relatively pristine. The lagoon is highly enclosed, and was characterized by reticulate patch and line reefs throughout the center of the lagoon as well as perimeter reefs around the rim of the atoll. The depth reached a maximum of 33.3 m in the central region of the lagoon, and averaged between 8.8 and 13.7 m in most of the pools. The deepest areas were found to harbor large platforms of Favia matthaii, which presumably provided a base upon which the dominant corals (Acropora spp.) grew to form the reticulate reef structure. The benthic algal communities consisted mainly of crustose coralline algae (CCA), microfilamentous turf algae and isolated patches of Halimeda spp. and Caulerpa spp. Fish species richness in the lagoon was half of that observed on the adjacent fore reef. The lagoon is likely an important nursery habitat for a number of important fisheries species including the blacktip reef shark and Napoleon wrasse, which are heavily exploited elsewhere around the world but were common in the lagoon at Millennium. The lagoon also supports an abundance of giant clams (Tridacna maxima). Millennium lagoon provides an excellent reference of a relatively undisturbed coral atoll. As with most coral reefs around the world, the lagoon communities of Millennium may be threatened by climate change and associated warming, acidification and sea level rise, as well as sporadic local resource exploitation which is difficult to monitor and enforce because of the atoll's remote location.

    Basing hypotheses on interpretations of 12 personality factors most replicated in 10 past researches with children, this experiment sets up about eight subtests as specific markers for each. Ninety-five tests, taking eight hours in all, were administered to 394 14-16-year olds. A majority of the personality pattern hypotheses were sustained factor analytically by evidence on number of factors, significance of unique simple structure reached, and goodness of identifying match (chi-square test). Concept validities can be obtained for some six of the factors rivalling those for intelligence tests. A brief discussion is given of the bearing of the present results upon theoretical explanations of the given source traits, including extraversion, and it is pointed out that the psychological meaning of most, for personality research, is as important, in variance terms, as for the one or two, such as anxiety and extraversion, which have tended to monopolize discussion.

    Background Law enforcement can shape HIV risk behaviours and undermine strategies aimed at curbing HIV infection. Little is known about factors that increase vulnerability to police victimization in Mexico. This study identifies correlates of police or army victimization (i.e., harassment or assault) in the past 6 months among patients seeking care at a free clinic in Tijuana, Mexico. Methods From January to May 2013, 601 patients attending a binational student-run free clinic completed an interviewer-administered questionnaire. Eligible participants were: (1) ≥18 years old; (2) seeking care at the clinic; and (3) spoke Spanish or English. Multivariate logistic regression analyses identified factors associated with police/army victimization in the past 6 months. Results More than one-third (38%) of participants reported victimization by police/army officials in the past 6 months in Tijuana. In multivariate logistic regression analyses, males (Adjusted Odds Ratio (AOR): 3.68; 95% CI: 2.19–6.19), tattooed persons (AOR: 1.56; 95% CI: 1.04–2.33) and those who injected drugs in the past 6 months (AOR: 2.11; 95% CI: 1.29–3.43) were significantly more likely to report past 6-month police/army victimization. Recent feelings of rejection (AOR: 3.80; 95% CI: 2.47–5.85) and being denied employment (AOR: 2.23; 95% CI: 1.50–3.32) were also independently associated with police/army victimization. Conclusion Structural interventions aimed at reducing stigma against vulnerable populations and increasing social incorporation may aid in reducing victimization events by police/army in Tijuana. Police education and training to reduce abusive policing practices may be warranted. PMID:25281235

    The sunspot number is the longest running direct index of solar activity, with direct measurements starting in 1610. For many purposes, e.g., for comparisons with climate indices, it is still too short. We present a reconstruction of the cycle-averaged sunspot number over the last millennium based on 10Be concentrations in Greenland and Antarctic ice cores. As intermediate steps of the method, we also reconstruct the cosmic ray flux at Earth and the Sun's open magnetic flux. The reconstructions are validated by comparison with direct measurements or independent reconstructions. We also compare with records of global climate, in particular with the global temperature ("hockey stick") curve of Mann et al (1998). A reasonable agreement is found for the entire millennium, excluding only the last decades, when the two curves start diverging from each other.

    Dispersal is one of the most fundamental components of ecology, and affects processes as diverse as population growth, metapopulation dynamics, gene flow and adaptation. Although the act of moving from one habitat to another entails major costs to the disperser, empirical and theoretical studies suggest that these costs can be reduced by having morphological, physiological or behavioural specializations for dispersal. A few recent studies on different systems showed that individuals exhibit personality-dependent dispersal, meaning that dispersal tendency is associated with boldness, sociability or aggressiveness. Indeed, in several species, dispersers not only develop behavioural differences at the onset of dispersal, but display these behavioural characteristics through their life cycle. While personality-dependent dispersal has been demonstrated in only a few species, we believe that it is a widespread phenomenon with important ecological consequences. Here, we review the evidence for behavioural differences between dispersers and residents, to what extent they constitute personalities. We also examine how a link between personality traits and dispersal behaviours can be produced and how personality-dependent dispersal affects the dynamics of metapopulations and biological invasions. Finally, we suggest future research directions for population biologists, behavioural ecologists and conservation biologists such as how the direction and the strength of the relationship between personality traits and dispersal vary with ecological contexts.

    It has been proved that Adolf Hitler suffered from idiopathic Parkinson's disease. No indication for postencephalitic parkinsonism was found in the clinical symptoms or the case history. Professor Max de Crinis established his diagnosis of Parkinson's disease in Hitler early in 1945 and informed the SS leadership, who decided to initiate treatment with a specially prepared 'antiparkinsonian mixture' to be administered by a physician. However, Hitler never received the mixture, this implies that the SS intended to remove the severely diseased 'Leader'. Two different character traits can be analysed in Hitler's personality: on the one hand the typical premorbid personality of parkinsonian patients with uncorrectable mental rigidity, extreme inflexibility and insupportable pedantry. On the other an antisocial personality disorder with lack of ethical and social values, a deeply rooted tendency to betray others and to deceive himself and uncontrollable emotional reactions. This special combination in Hitler's personality resulted in the uncritical conviction of his mission and an enormous driving for recognition. The neuropsychiatric analysis of Hitler's personality could lead to a better explanation of the pathological traits of one of the most conspicuous historical personalities. PMID:10053222

    Earth Orbiter 1 (EO-1) is the first in a series of Earth Orbiter spacecraft for NASA's New Millennium Program (NMP). Government, academia and industry have been teamed together to develop the EO-1 spacecraft. The mission, instruments, NMP technologies, and spacecraft subsystems are discussed. The remote sensing science instruments which will be flown on the EO-1 spacecraft are the Advanced Land Imager and the Atmospheric Corrector. The NMP technologies planned for spaceflight validation by EO-1 include an X-band phased array antenna, a pulsed plasma thruster, a high-rate fiber optic data bus, a lightweight flexible solar array, formation flight with Landsat-7, and carbon-carbon thermal radiators. The data subsystem contains several new technologies. Other subsystems include attitude control, power, RF communications, structure and mechanisms, and thermal subsystem. The EO-1 mission is a good example of the faster-better-cheaper philosophy that NASA has adopted for its spacecraft, and paves the way for constructing future spacecraft in the new millennium.

    The Last Millennium simulation of the Community Climate System Model version 4 (CCSM4) reproduces many large-scaled climate patterns suggested by historical and proxy-data records including cooling from the Medieval Climate Anomaly to the Little Ice Age, a "hockey-stick" pattern of surface temperature changes from 850-2005, and a broad cooling with a delayed La Niña-type of pattern in the tropical Pacific response to large volcanic events. Atmospheric modes, one oceanic mode (the Pacific Decadal Oscillation), and one ocean-atmosphere coupled mode (the El Niño-Southern Oscillation) of variability show little or no change in their variances, teleconnection patterns and spectra between the Last Millennium simulation and the 1850 non-transient control run. Two oceanic modes, the Atlantic Multidecadal Oscillation and the Atlantic Meridional Overturning Circulation have higher variances and increased power at low frequencies in the Last Millennium simulation compared with the control run, suggesting long-term oceanic response to natural solar and volcanic forcings.

  11. Telepathology: a diagnostic tool for the millennium?

    PubMed

    2000-05-01

    Many developments in science have their origins in science fiction and telepathology is no exception. The concept was first illustrated in 1924 in the magazine 'Radio News'. It was not until 1980, however, that the first working telepathology system was demonstrated. Although the system was shown to work, it required special hardware, dedicated software and special microwave transmission links to be installed. Little interest was shown worldwide because of the very high cost and the inability of many people to replicate such a system. Ten years later, the personal computer (PC) was able to provide more than adequate performance at low cost for both image display quality and speed, and the development of video technology had resulted in high quality images being produced by television cameras that were now easily affordable. Microscopes were also relatively cheaper. Thus, by 1993 or 1994, all the hardware necessary to produce a telepathology system was available at reasonable cost. Telepathology can now be used for remote primary diagnosis, remote referral to a specialist pathologist, remote teaching, remote presentation of post-mortem or microscopic findings, quality assurance image circulation and feedback, and consensus diagnosis for pathological review in clinical trials. There are two residual problems. The first concerns the speed of data transmission, commonly referred to as the bandwidth. The second is that the software provided by most of the manufacturers and suppliers of these systems is not entirely suitable to the task and the systems are not interoperable. It is clear that the approach of the manufacturers is at present unlikely to produce telepathology systems which pathologists feel comfortable in using. A somewhat different approach is illustrated by the accompanying article in this issue from the Berlin group, where a relatively simple Java-based applet and the Internet are used to allow single or multiple users to view slides on a robotic

It measures the frequencies of pertinent personal and occupational factors, and uses multivariate analysis to explore relationships between these factors. RESULTS. Most physicians in Estonia are women and work in urban settings. About half of the physicians work in hospitals, and one third work in large outpatient clinics called polyclinics. About one third work in primary care. Gender affects education, specialty, type of workplace, and administrative duties; nationality affects education and administrative duties. CONCLUSIONS. The Soviet system of health care derived its professional structure from a combination of personal and occupational factors. Those considering options for reform of the health care systems of the newly independent states that once constituted the Soviet Union should appreciate the nature of these structural forces.

  13. Structured Decision-Making: Using Personalized Medicine to Improve the Value of Cancer Care

    Cancer care is often inconsistently delivered with inadequate incorporation of patient values and objective evidence into decision-making. Utilization of time limited trials of care with predefined decision points that are based on iteratively updated best evidence, tools that inform providers about a patient’s experience and values, and known information about a patient’s disease will allow superior matched care to be delivered. Personalized medicine does not merely refer to the incorporation of genetic information into clinical care, it involves utilization of the wide array of data points relevant to care, many of which are readily available at the bedside today. By pushing uptake of personalized matching available today, clinicians can better address the triple aim of improved health, lowers costs, and enhanced patient experience, and we can prepare the health care landscape for the iterative inclusion of progressively more sophisticated information as newer tests and information become available to support the personalized medicine paradigm.

    Although cognitive and personality studies have observed gender differences in narcissism, the neural bases of these differences remain unknown. The current study combined the voxel-based morphometry and resting state functional connectivity (rsFC) analyses to explore the sex-specific neural basis of narcissistic personality. The VBM results showed that the relationship between narcissistic personality and regional gray matter volume (rGMV) differed between sexes. Narcissistic scores had a significant positive correlation with the rGMV of the right SPL in females, but not in males. Further analyses were conducted to investigate the sex-specific relationship between rsFC and narcissism, using right SPL/frontal eye fields (FEF) as the seed regions (key nodes of the dorsal attention network, DAN). Interestingly, decreased anticorrelations between the right SPL/FEF and areas of the precuneus and middle frontal gyrus (key nodes of the the default mode network, DMN) were associated with higher narcissistic personality scores in males, whereas females showed the opposite tendency. The findings indicate that gender differences in narcissism may be associated with differences in the intrinsic and dynamic interplay between the internally-directed DMN and the externally-directed TPN. Morphometry and functional connectivity analyses can enhance our understanding of the neural basis of sex-specific narcissism. PMID:26109334

  17. Investigating the structure of semantic networks in low and high creative persons

    According to Mednick's (1962) theory of individual differences in creativity, creative individuals appear to have a richer and more flexible associative network than less creative individuals. Thus, creative individuals are characterized by “flat” (broader associations) instead of “steep” (few, common associations) associational hierarchies. To study these differences, we implement a novel computational approach to the study of semantic networks, through the analysis of free associations. The core notion of our method is that concepts in the network are related to each other by their association correlations—overlap of similar associative responses (“association clouds”). We began by collecting a large sample of participants who underwent several creativity measurements and used a decision tree approach to divide the sample into low and high creative groups. Next, each group underwent a free association generation paradigm which allowed us to construct and analyze the semantic networks of both groups. Comparison of the semantic memory networks of persons with low creative ability and persons with high creative ability revealed differences between the two networks. The semantic memory network of persons with low creative ability seems to be more rigid, compared to the network of persons with high creative ability, in the sense that it is more spread out and breaks apart into more sub-parts. We discuss how our findings are in accord and extend Mednick's (1962) theory and the feasibility of using network science paradigms to investigate high level cognition. PMID:24959129

    2015-01-01

    Psychopathy is a complex personality disorder characterized by affective, interpersonal, and behavioral dimensions. Although features of psychopathy have been extended downwardly to earlier developmental periods, there is a discerning lack of studies that have focused on critically important issues such as longitudinal invariance and stability/change in these features across time. The current study examines these issues using a large sample of male adolescent offenders (N = 1,170) assessed across 7 annual time points during the transition into emerging adulthood (ages ~ 17 to 24 years). Findings demonstrated that features of psychopathy remained longitudinally invariant across this developmental period, and showed temporally consistent and theoretically coherent associations with other measures of personality, psychopathology, and criminal behaviors. Results also demonstrated that mean levels of psychopathic personality features tended to decrease into emerging adulthood and showed relatively modest rank-order stability across assessments with 7-year lags. These findings suggest that reductions in maladaptive personality features seem to parallel the well-documented decreases in offending that occur during the early 20s. PMID:24978692

    This study compared a series of higher-order models encompassing symptoms of both clinical and personality disorders. The final model was then correlated with a latent variable model of normal personality traits. A total of 420 undergraduates completed a battery of self-report symptom and personality questionnaires, with informant-reports and diagnostic interviews provided by overlapping subsamples. A three-level model with two factors at the highest level and four factors at the second level was the best fitting model. The higher-order internalizing and externalizing factors were then correlated with 30 latent personality facets. Results demonstrate an elevation on the neuroticism facets for the higher-order internalizing factor, along with low positive emotions, low actions, and low competence. The higher-order externalizing factor was negatively associated with most conscientiousness and agreeableness factors, while showing an elevation on excitement-seeking, impulsivity, and angry hostility. Future studies should replicate these models with the inclusion of more low base-rate disorders (i.e., psychosis). PMID:25893555

    In a recent contribution, Bahl and Baumgardt investigated the incidence of planar alignments of satellite galaxies in the Millennium-II simulation and concluded that vast, thin planes of dwarf galaxies, similar to that observed in the Andromeda galaxy (M31), occur frequently by chance in Λ-cold dark matter cosmology. However, their analysis did not capture the essential fact that the observed alignment is simultaneously radially extended, yet thin, and kinematically unusual. With the caveat that the Millennium-II simulation may not have sufficient mass resolution to identify confidently simulacra of low-luminosity dwarf galaxies, we re-examine that simulation for planar structures, using the same method as employed by Ibata et al. on the real M31 satellites. We find that 0.04% of host galaxies display satellite alignments that are at least as extreme as the observations, when we consider their extent, thickness, and number of members rotating in the same sense. We further investigate the angular momentum properties of the co-planar satellites, and find that the median of the specific angular momentum derived from the line-of-sight velocities in the real M31 structure (1.3 × 10{sup 4} km s{sup –1} kpc) is very high compared to systems drawn from the simulations. This analysis confirms that it is highly unlikely that the observed structure around the Andromeda galaxy is due to a chance occurrence. Interestingly, the few extreme systems that are similar to M31 arise from the accretion of a massive sub-halo with its own spatially concentrated entourage of orphan satellites.

    2014-05-01

    The Earth's climate system is driven by a complex interplay of internal chaotic dynamics and natural and anthropogenic external forcing. Recent instrumental data have shown a remarkable degree of asynchronicity between Northern Hemisphere and Southern Hemisphere temperature fluctuations, thereby questioning the relative importance of internal versus external drivers of past as well as future climate variability. However, large-scale temperature reconstructions for the past millennium have focused on the Northern Hemisphere, limiting empirical assessments of inter-hemispheric variability on multi-decadal to centennial timescales. Here, we introduce a new millennial ensemble reconstruction of annually resolved temperature variations for the Southern Hemisphere based on an unprecedented network of terrestrial and oceanic palaeoclimate proxy records. In conjunction with an independent Northern Hemisphere temperature reconstruction ensemble, this record reveals an extended cold period (1594-1677) in both hemispheres but no globally coherent warm phase during the pre-industrial (1000-1850) era. The current (post-1974) warm phase is the only period of the past millennium where both hemispheres are likely to have experienced contemporaneous warm extremes. Our analysis of inter-hemispheric temperature variability in an ensemble of climate model simulations for the past millennium suggests that models tend to overemphasize Northern Hemisphere-Southern Hemisphere synchronicity by underestimating the role of internal ocean-atmosphere dynamics, particularly in the ocean-dominated Southern Hemisphere. Our results imply that climate system predictability on decadal to century timescales may be lower than expected based on assessments of external climate forcing and Northern Hemisphere temperature variations alone.

  12. Northern high latitude climate variability of the last millennium

    NASA Astrophysics Data System (ADS)

    Andres, Heather J.

    This work explores the causes of northern high-latitude climate variations over the last millennium, and industrial and future periods. Attribution studies are performed on a suite of global climate simulations, and four historical reconstructions of Greenland surface temperatures and precipitation (two of which are new to this work). The simulations followed the protocols of the Palaeoclimate Modelling Intercomparison Project 3 and Coupled Model Intercomparison Project 5. At least half of the multi-decadal variability in simulated Greenland climate variations over the last millennium is reproduced by a linear, empirically-generated model including terms for volcanic emissions, solar insolation changes (including total solar irradiance and orbital components) and an index associated with latitudinal shifts in the North Atlantic jet. Empirical model parameters are obtained by regressing simulated Greenland temperatures and precipitation against time series for each of the response variables. Greenhouse gas radiative forcing changes are unimportant to simulated Greenland conditions over the last millennium, although they dominate after the mid-20th century. Most of the historical Greenland climate reconstructions are restricted to the industrial period, due to a lack of spatially-comprehensive climate records. They exhibit substantial differences in the timing, phasing and amplitudes of past climate variations, due to regional sensitivities in the source data and the reconstruction methodologies. Reconstructions indicate that Greenland temperatures did not begin to follow hemispheric greenhouse gas warming patterns until the mid-1990s. This discrepancy indicates either that the warming hiatus was associated with internal climate variability, or that the simulations are missing processes important to Greenland climate. For example, indirect effects of anthropogenic aerosols are not captured in the climate model employed here. All of the external climate forcings

    Soon after the crowd streamed on to London's Millennium Bridge on the day it opened, the bridge started to sway from side to side: many pedestrians fell spontaneously into step with the bridge's vibrations, inadvertently amplifying them. Here we model this unexpected and now notorious phenomenon - which was not due to the bridge's innovative design as was first thought - by adapting ideas originally developed to describe the collective synchronization of biological oscillators such as neurons and fireflies. Our approach should help engineers to estimate the damping needed to stabilize other exceptionally crowded footbridges against synchronous lateral excitation by pedestrians.

    As the new millennium dawns, Australian society is becoming more post-modern, whereas the medical system remains increasingly modernist in its outlook. In this article, we discuss the emerging prevalence of post-modernism and examine current medical education and practice strategies, such as evidence-based medicine, from a post-modern perspective. We argue that if medicine does not respond to the ideas of post-modernism, which challenges the concepts of truth and our ability to be objective, it may become increasingly irrelevant to the needs of a changing society.

    Archaeological and soil-stratigraphic data define the origin, growth, and collapse of Subir, the third millennium rain-fed agriculture civilization of northern Mesopotamia on the Habur Plains of Syria. At 2200 B.C., a marked increase in aridity and wind circulation, subsequent to a volcanic eruption, induced a considerable degradation of land-use conditions. After four centuries of urban life, this abrupt climatic change evidently caused abandonment of Tell Leilan, regional desertion, and collapse of the Akkadian empire based in southern Mesopotamia. Synchronous collapse in adjacent regions suggests that the impact of the abrupt climatic change was extensive.

    2016-05-01

    Research on the structure of children's affect is limited. It is possible that children's perception of their own affect might be less differentiated than that of adults. Support for the 2-factor model of positive and negative affect and the pleasure-arousal model suggests that children in middle childhood can distinguish positive and negative affect as well as valence and arousal. Whether children are able to differentiate further aspects of affect, as proposed by the 3-dimensional model of affect (good-bad mood, alertness-tiredness, calmness-tension), is an unresolved issue. The aim of our study was the comparison of these 3 affect models to establish how differentiated children experience their affect and which model best describes affect in children. We examined affect structures on the between- and within-person level, acknowledging that affect varies across time and that no valid interpretation of either level is feasible if both are confounded. For this purpose, 214 children (age 8-11 years) answered affect items once a day for 5 consecutive days on smartphones. We tested all affect models by means of 2-level confirmatory factor analysis. Although all affect models had an acceptable fit, the 3-dimensional model best described affect in children on both the within- and between-person level. Thus, children in middle childhood can already describe affect in a differentiated way. Also, affect structures were similar on the within- and between-person level. We conclude that in order to acquire a thorough picture of children's affect, measures for children should include items of all 3 affect dimensions. (PsycINFO Database Record PMID:26280488

    This study sought to confirm a multi-factor model of Obsessive-compulsive personality disorder (OCPD) in a Hispanic outpatient sample and to explore associations of the OCPD factors with aggression, depression, and suicidal thoughts. One hundred and thirty monolingual, Spanish-speaking participants were recruited from a community mental health center and were assessed by bilingual doctoral level clinicians. OCPD was highly prevalent (26%) in this sample. Multi-factor models of OCPD were tested and the two factors - perfectionism and interpersonal rigidity - provided the best model fit. Interpersonal rigidity was associated with aggression and anger while perfectionism was associated with depression and suicidal thoughts. PMID:20227063

    Purpose To report preliminary comparisons of developing structural characteristics associated with fictional and personal narratives in school-age African American children. Method Forty-three children, grades two through five, generated a fictional and a personal narrative in response to a wordless-book elicitation task and a story-prompt task, respectively. Narratives produced in these two contexts were characterized for macrostructure, microstructure, and dialect density. Differences across narrative type and grade level were examined. Results Statistically significant differences between the two types of narratives were found for both macrostructure and microstructure but not for dialect density. There were no grade-related differences in macrostructure, microstructure, or dialect density. Conclusion The results demonstrate the complementary role of fictional and personal narratives for describing young children's narrative skills. Use of both types of narrative tasks and descriptions of both macrostructure and macrostructure may be particularly useful for characterizing the narrative abilities of young school-age African American children, for whom culture-fair methods are scarce. Further study of additional dialect groups is warranted. PMID:23633645

    Division of labor is a defining characteristic of social insects and fundamental to their ecological success.

    Division of labor is a defining characteristic of social insects and fundamental to their ecological success.

    High Performance Computing facilities face increased pressures to survive and thrive in the next millennium. HPC facilities must combine effective techniques of the past with innovative methods of the future. This tutorial explores requirements and pressures on HPC centers, and presents effective methods being employed and new approaches to employ to overcome these challenges. Topics include: The current state of HPC computing and projections; System management that allows MPPs running many large jobs to achieve greater than 90% utilization of CPUs; Archive storage issues of improving transfer bandwidth and practical advice for running Terabyte archives; Innovations for client services to ensure the ''intellectual resource'' is equally val2048by clients as the systems; Introduce the Effective System Performance Test a new way to objectively measure and compare not just system performance (e.g. sustained performance of applications) but also system effectiveness (e.g. how many system resources, especially CPU time can really be used by the workload over time); Integrating production with a good is critical to maintaining a robust HPC facility: The tutorial will address how to achieve and maintain this delicate balance. It explores what a facility needs to do to thrive in the new millennium.

    Within the Central Asian Climate Dynamics project (CADY), we aim to apply multiproxy reconstructions and climate models to analyse and (semi)quantify the Last Millennium climate variability and regional hydrology in Central Asia. In this context, we have used simulations of the uncoupled atmosphere version of global COSMOS Model (ECHAM5) in T31L19 spatial resolution within the Last Millennium; Medieval Warm Period (MWP; 900-1100 AD), the Little Ice Age (LIA; 1515-1715 AD) and after industrialization (REC; 1800-2000 AD) to drive the COSMO-CLM regional climate model at its lateral boundaries for 30 year time-slices based on the definition of extreme spells in the past climate. The Palmer Drought Severity Index over Central Asia has been calculated for both global and regional simulations. The simulated PDSI from COSMO-CLM driven by ERA-INTERIM data shows very good agreements compared to observations (PDSI from Dai et al., 2004) in space-time-frequency. Based on the EOF analysis, the simulated drought patterns are well captured compared to the reconstructed PDSI from Cook et al., 2010 ( pattern correlation = 0.68 (0.83) for LIA(REC) at a 99% significance level). Further, historical droughts can be identified by the simulated PDSI (e.g. Ming Dynasty Drought and The Great Drought). The Principal Components of simulated PDSI also show significant correlations with SST anomalies for the period from 1856 to 2000.

    Objective Research has demonstrated poor agreement between clinician-assigned personality disorder (PD) diagnoses and those generated by self-report questionnaires and semi-structured diagnostic interviews. No research has compared prospectively the predictive validity of these methods. We investigated the convergence of these three diagnostic methods and tested their relative and incremental validity in predicting independent, multi-method assessments of psychosocial functioning performed prospectively over five years. Method Participants were 320 patients in the Collaborative Longitudinal Personality Disorders Study (CLPS) diagnosed with PDs by therapist, self-report, and semi-structured interview at baseline. We examined the relative incremental validity of therapists’ naturalistic ratings relative to these other diagnostic methods for predicting psychosocial functioning at five-year follow-up. Results Hierarchical linear regression analyses revealed that both the self-report questionnaire and semi-structured interview PD diagnoses had significant incremental predictive validity over the PD diagnoses assigned by a treating clinician. Although in some cases the clinicians’ ratings for individual PDs did have validity for predicting subsequent functioning, they did not generally provide incremental prediction beyond the other methods. These findings remained robust in a series of analyses restricted to a subsample of therapist ratings based on clinical contact of one year or greater. Conclusions These results from a large clinical sample echo previous research documenting limited agreement between clinicians’ naturalistic PD diagnoses and those from self-report and semi-structured interview methods. They extend prior work by providing the first evidence about the relative predictive validity of these different methods. Our findings challenge the validity of naturalistic PD diagnoses and suggest the use of structured diagnostic instruments. PMID:23647282

  10. Hemispherically Asymmetric Volcanic Forcing of Tropical Hydroclimate During the Last Millennium

    Volcanic aerosols exert the most important natural radiative forcing of the last millennium. State-of-the-art paleoclimate simulations of this interval are typically forced with diverse spatial patterns of volcanic forcing, leading to different responses in tropical hydroclimate. Recently, theoretical considerations relating the intertropical convergence zone (ITCZ) position to the demands of global energy balance have emerged in the literature, allowing for a connection to be made between the paleoclimate simulations and recent developments in the understanding of ITCZ dynamics. These energetic considerations aid in explaining the well-known historical, paleoclimatic, and modeling evidence that the ITCZ migrates away from the hemisphere that is energetically deficient in response to asymmetric forcing. Here we use two separate general circulation model (GCM) suites of experiments for the last millennium to relate the ITCZ position to asymmetries in prescribed volcanic sulfate aerosols in the stratosphere and related asymmetric radiative forcing. We discuss the ITCZ shift in the context of atmospheric energetics and discuss the ramifications of transient ITCZ migrations for other sensitive indicators of changes in the tropical hydrologic cycle, including global streamflow. For the first time, we also offer insight into the large-scale fingerprint of water isotopologues in precipitation (delta sup 18 Op) in response to asymmetries in radiative forcing. The ITCZ shifts away from the hemisphere with greater volcanic forcing. Since the isotopic composition of precipitation in the ITCZ is relatively depleted compared to areas outside this zone, this meridional precipitation migration results in a large-scale enrichment (depletion) in the isotopic composition of tropical precipitation in regions the ITCZ moves away from (toward). Our results highlight the need for careful consideration of the spatial structure of volcanic forcing for interpreting volcanic signals in

  11. Personal protection: vicarious liability as applied to the various business structures.

    2008-01-01

    Within the field of midwifery, the issue of vicarious liability has become an emerging issue. The doctrine of respondeat superior imputes liability to an employer without direct negligence. While the issue of vicarious liability has been explored in the past, those studies were focused on the vicarious liability of certified nurse-midwives/certified midwives (CNMs/CMs) for the negligence of their employees. This article explores the issue of vicarious liability under the doctrine of respondeat superior as applied within a practice consisting of two or more co-owners. This issue is of heightened importance, because CNMs/CMs increasingly enter into ventures with other CNMs/CMs in order to pool their resources. Many CNMs/CMs unsuspectingly assume the risks for the malpractice of their colleagues. This increased risk can be minimized by forming their practice as a limited liability entity, thus avoiding personal liability for the malpractice of their co-owner(s). PMID:18308265

    Multidrug and toxin extrusion (MATE; SLC47A) proteins are membrane transporters mediating the excretion of organic cations and zwitterions into bile and urine and thereby contributing to the hepatic and renal elimination of many xenobiotics. Transported substrates include creatinine as endogenous substrate, the vitamin thiamine and a number of drug agents with in part chemically different structures such as the antidiabetic metformin, the antiviral agents acyclovir and ganciclovir as well as the antibiotics cephalexin and cephradine. This review summarizes current knowledge on the structural and molecular features of human MATE transporters including data on expression and localization in different tissues, important aspects on regulation and their functional role in drug transport. The role of genetic variation of MATE proteins for drug pharmacokinetics and drug response will be discussed with consequences for personalized medicine. PMID:27165417

    The internal working model of attachment has been assessed through attachment interviews and story-stems that exhibit differentiated patterns in adult and child narratives. This study examined variation in length and structure of children's independent personal narratives by attachment representations, discriminating between insecure-avoidant and insecure-ambivalent, and we tested attachment insecurity as a predictor of developmental delay in narrative discourse. Sixty-five preschool-age children completed the Attachment Story Completion Task-Revised and recalled three recent past events. Secure children told longer personal narratives than both avoidant and ambivalent children, and secure children's narrative structure was more coherent than that of ambivalent children but not avoidant children. Likewise, the two insecure categories differentially predicted delayed discourse. Ambivalent children were 10 times more likely to exhibit delayed discourse than secure children, whereas avoidant children were not at significantly greater risk. Differential developmental outcomes of avoidant and ambivalent children are discussed and conclusions are drawn about the role of child attachment in storing, accessing and communicating memories about everyday lived experiences.

    The objective of this project was to develop a user-friendly interactive computer program to be used as an analytical tool by structural designers. Its intent was to do preliminary, approximate stress analysis to help select or verify sizing choices for composite structural members. The approach to the project was to provide a subroutine which uses classical lamination theory to predict an effective elastic modulus for a laminate of arbitrary material and ply orientation. This effective elastic modulus can then be used in a family of other subroutines which employ the familiar basic structural analysis methods for isotropic materials. This method is simple and convenient to use but only approximate, as is appropriate for a preliminary design tool which will be subsequently verified by more sophisticated analysis. Additional subroutines have been provided to calculate laminate coefficient of thermal expansion and to calculate ply-by-ply strains within a laminate.

    Summary The University Personality Inventory, a mental health instrument for college students, is frequently used for screening in China. However, its unidimensionality has been questioned. This study examined its dimensions to provide more information about the specific mental problems for students at risk. Four subsamples were randomly created from a sample (N = 6,110; M age = 19.1 yr.) of students at a university in China. Principal component analysis with Promax rotation was applied on the first two subsamples to explore dimension of the inventory. Confirmatory factor analysis was conducted on the third subsample to verify the exploratory dimensions. Finally, the identified factors were compared to the Sympton Checklist–90 (SCL–90) to support validity, and sex differences were examined, based on the fourth subsample. Five factors were identified: Physical Symptoms, Cognitive Symptoms, Emotional Vulnerability, Social Avoidance, and Interpersonal Sensitivity, accounting for 60.3% of the variance. All the five factors were significantly correlated with the SCL–90. Women significantly scored higher than men on Cognitive Symptoms and Interpersonal Sensitivity. PMID:25933045

    Psychedelic agents have a long history of use by humans for their capacity to induce profound modifications in perception, emotion and cognitive processes. Despite increasing knowledge of the neural mechanisms involved in the acute effects of these drugs, the impact of sustained psychedelic use on the human brain remains largely unknown. Molecular pharmacology studies have shown that psychedelic 5-hydroxytryptamine (5HT)2A agonists stimulate neurotrophic and transcription factors associated with synaptic plasticity. These data suggest that psychedelics could potentially induce structural changes in brain tissue. Here we looked for differences in cortical thickness (CT) in regular users of psychedelics. We obtained magnetic resonance imaging (MRI) images of the brains of 22 regular users of ayahuasca (a preparation whose active principle is the psychedelic 5HT2A agonist N,N-dimethyltryptamine (DMT)) and 22 controls matched for age, sex, years of education, verbal IQ and fluid IQ. Ayahuasca users showed significant CT differences in midline structures of the brain, with thinning in the posterior cingulate cortex (PCC), a key node of the default mode network. CT values in the PCC were inversely correlated with the intensity and duration of prior use of ayahuasca and with scores on self-transcendence, a personality trait measuring religiousness, transpersonal feelings and spirituality. Although direct causation cannot be established, these data suggest that regular use of psychedelic drugs could potentially lead to structural changes in brain areas supporting attentional processes, self-referential thought, and internal mentation. These changes could underlie the previously reported personality changes in long-term users and highlight the involvement of the PCC in the effects of psychedelics. PMID:25637267

    Aims This study examined the personality traits of negative emotionality and constraint and the ability to resist drinking during negative affective states as correlates of solitary drinking in adolescence. We hypothesized that higher levels of negative emotionality and lower levels of constraint would predict solitary drinking and that these relationships would be mediated by the ability to resist drinking in response to negative emotions. Design Structural equation modeling was used to fit a path model from the personality traits of negative emotionality and constraint to solitary drinking status through intermediate effects on the ability to resist drinking during negative emotions using cross-sectional data. Setting Clinical and community settings in Pennsylvania, USA. Participants The sample included 761 adolescent drinkers (mean age = 17.1). Measurements Adolescents completed the Lifetime Drinking History, the Multidimensional Personality Questionnaire, the Constructive Thinking Inventory and the Situational Confidence Questionnaire. Findings The path model provided a good fit to the data. The association between trait negative emotionality and solitary drinking was fully mediated by adolescents' ability to resist drinking during negative affective states (b = 0.05, P = 0.01). In contrast, constraint had a direct effect on solitary drinking (odds ratio (OR) = 0.79, b = –0.23, P<0.01), as well as an indirect effect through the ability to resist drinking during negative affective states (b = –0.03, P = 0.02). Conclusions The ability to resist drinking while experiencing negative feelings or emotions may be an important underlying mechanism linking trait negative emotionality (a tendency toward depression, anxiety and poor reaction to stress) and constraint (lack of impulsiveness) to adolescent solitary drinking.

    Lead is one of the industrially heavy metals that caused adverse effects on male reproductive system among battery factory workers, but information on the possible impact of lead on the structural integrity of sperm cell is limited. Thus present study was undertaken to assess the structural details of human spermatozoa of lead acid battery factory workers. Blood and semen samples were collected from total 80 workers (7-15 years exposure) and 40 non-occupationally exposed control subjects. The lead exposed battery factory workers showed lowering (P < 0.001) of sperm count, density, motility and semen volume along with an increase incidence of sperm abnormality and prolong liquefaction time. Structural alteration of sperm cell was prevalent among the exposed population as evidenced by significantly (P < 0.001) low sperm viability, low hypoosmotic swelling test (HOST) percentage, high lipid peroxidation of sperm membrane with concomitant alterations of seminal plasma total and dehydro ascorbate level. Sharp depressions, membrane folding and granularity at sperm head surfaces were observed by scanning electron microscopy (SEM). Both blood lead and semen lead was significantly (P < 0.001) higher among the factory workers. Thus it appears plausible that lead may reduce the antioxidant level in seminal plasma and enhance the lipid peroxidative changes in sperm membrane leading to concomitant structural damage of sperm cell surface in the workers employed in lead acid battery factories.

    The last total solar eclipse of the millennium will be observed from Turkey which bridges two continents and has been the cradle of so many past civilizations. Wouldn't you like to witness this magnificent event in the mystic ambiance of central Anatolia which offers its guests Turkish hospitality and a lot of historical examples of paganism, Christianity and Islam. Among the countries from which the eclipse will be visible, Turkey seems to be one of the most suitable countries in terms of its climate and observational facilities. Kandilli Observatory and Earthquake Research Institute has arranged fieldwork on the eclipse path to determine the suitable points for the observations. The shadow of the moon will be first seen from the Black Sea coast at 14:20 L.T. It will then pass through central Anatolia and will leave Turkey from south-east at 14:42 L.T.

  5. Questions of identity in the millennium round of Commonwealth censuses.

    Christopher, A J

    2006-11-01

    All Commonwealth census authorities have posed questions about identity in the millennium round of enumerations. The most controversial issue has been ethnicity. No universal definition or classification system has been devised and each of the 71 states and dependencies has tended to pursue the enquiry in virtual isolation from its neighbours. The attempt to describe the population in terms of race and ethnicity has been inherited from the colonial era. More recently the requirements of monitoring affirmative-action programmes in multicultural populations have resulted in the introduction or refinement of questions on these categories. A few states-a small minority of Commonwealth countries-remain hostile to such enquiries. Where the issues of race and identity are not pursued, questions of nationality, language, and religion often fill the gaps left, adding further refinements to the definition of identity. An examination of current questioning about identity in Commonwealth censuses reveals a highly complex picture. PMID:17060057

    An intelligent robot is a remarkably useful combination of a manipulator, sensors and controls. The current use of these machines in outer space, medicine, hazardous materials, defense applications and industry is being pursued with vigor but little funding. In factory automation such robotics machines can improve productivity, increase product quality and improve competitiveness. The computer and the robot have both been developed during recent times. The intelligent robot combines both technologies and requires a thorough understanding and knowledge of mechatronics. In honor of the new millennium, this paper will present a discussion of futuristic trends and predictions. However, in keeping with technical tradition, a new technique for 'Follow the Leader' will also be presented in the hope of it becoming a new, useful and non-obvious technique.

    The Millennium Development Goals have galvanized efforts to improve child survival (MDG-4) and maternal health (MDG-5). There has been important progress on both MDGs at global level, although it now appears that few countries will reach them by the target date of 2015. There are known and efficacious interventions to address most of the major causes of these deaths, but important gaps remain. The biggest challenge is to ensure that all women and children have access to life-saving interventions. Current levels of intervention coverage are too low, representing missed opportunities. Providing services at the community level is an important emerging priority, but preventing maternal and neonatal deaths also requires access to health facilities. Readers of the Medicine for Global Health collection in BMC Medicine are urged to make maternal and child health one of their key concerns, even if they work on other topics. PMID:24228742

    NASA's New Millennium Program (NMP) seeks to advance space exploration by providing an in-space validating mechanism to verify the maturity of promising advanced technologies that cannot be adequately validated with Earth-based testing alone. In meeting this objective, NMP uses NASA Technology Readiness Levels (TRL) as key indicators of technology advancement and assesses development progress against this generalized metric. By providing an opportunity for in-space validation, NMP can mature a suitable advanced technology from TRL 4 (component and/or breadboard validation in laboratory environment) to a TRL 7 (system prototype demonstrated in an Earth-based space environment). Spaceflight technology comprises a myriad of categories, types, and functions, and as each individual technology emerges, a consistent interpretation of its specific state of technological advancement relative to other technologies is problematic.

The mission goals are to demonstrate the research-quality science capability of the ST-5 spacecraft; to operate the three spacecraft as a constellation; and to design, develop and flight-validate three capable microsatellites with new technologies. ST-5 will be launched by a Pegasus XL into an elliptical polar (sun-synchronous) orbit. The three-month flight demonstration phase, beginning in March 2006, will validate the ability to perform science measurements, as well as the technologies and constellation operations. ST-5's technologies and concepts will enable future microsatellite science missions.

  12. Exocrine drainage in vascularized pancreas transplantation in the new millennium

    The history of vascularized pancreas transplantation largely parallels developments in immunosuppression and technical refinements in transplant surgery. From the late-1980s to 1995, most pancreas transplants were whole organ pancreatic grafts with insulin delivery to the iliac vein and diversion of the pancreatic ductal secretions to the urinary bladder (systemic-bladder technique). The advent of bladder drainage revolutionized the safety and improved the success of pancreas transplantation. However, starting in 1995, a seismic change occurred from bladder to bowel exocrine drainage coincident with improvements in immunosuppression, preservation techniques, diagnostic monitoring, general medical care, and the success and frequency of enteric conversion. In the new millennium, pancreas transplants are performed predominantly as pancreatico-duodenal grafts with enteric diversion of the pancreatic ductal secretions coupled with iliac vein provision of insulin (systemic-enteric technique) although the systemic-bladder technique endures as a preferred alternative in selected cases. In the early 1990s, a novel technique of venous drainage into the superior mesenteric vein combined with bowel exocrine diversion (portal-enteric technique) was designed and subsequently refined over the next ≥ 20 years to re-create the natural physiology of the pancreas with first-pass hepatic processing of insulin. Enteric drainage usually refers to jejunal or ileal diversion of the exocrine secretions either with a primary enteric anastomosis or with an additional Roux limb. The portal-enteric technique has spawned a number of newer and revisited techniques of enteric exocrine drainage including duodenal or gastric diversion. Reports in the literature suggest no differences in pancreas transplant outcomes irrespective of type of either venous or exocrine diversion. The purpose of this review is to examine the literature on exocrine drainage in the new millennium (the purported

    Persistent problems in emotional regulation and interpersonal relationships in borderline patients can be understood as developing from difficulties in early dyadic regulation with primary caregivers. Early attachment patterns are a relevant causal factor in the development of Borderline Personality Disorder (BPD). Links between attachment issues, early history of neglect, and traumatic experiences, and symptoms observed in patients with BPD as per the DSM-5 classification (American Psychiatric Association: Diagnostic and statistical manual of mental disorders: DSM-5 (Fifth ed.). Washington, D.C; (2013)) are described in this article, while delineating possible pathways from attachment disruptions to the specific symptomatology of these patients. The theory of structural dissociation of the personality (TSDP) provides an essential framework for understanding the processes that may lead from insecure early attachment to the development and maintenance of BPD symptoms. Dyadic parent-child interactions and subsequent modulation of emotion in the child and future adult are considered closely related, but other factors in the development of BPD, such as genetic predisposition and traumatic experiences, should also be considered in conceptualizing and organizing clinical approaches based on a view of BPD as a heterogeneous disorder.

    The case of a 30-year-old woman with five distinct personalities is presented. The patient was treated, using a system of structured video taped sodium amobarbital interviews, in which areas to be explored were developed in psychotherapy. Tapes were played for the patient after each session. The taped material was used as the basis for psychotherapeutic investigation. The patient evidenced many of the features previously reported in cases of multiple personality, specifically: being the product of an unwanted pregnancy in a repressively rigid family; emotional distancing by one parent; strong sibling rivalry with an adopted sib; family history of mental illness; a traumatic first sexual experience (rape); a marriage to a maladjusted individual in an attempt to escape the parental home; a high internalized standard of performance and an inability to display anger or negative feelings toward the parents. In the course of treatment, the patient's personalties fused and she was able to accept each component as part of herself. No further fragmentation has occurred during the year following discharge. The therapy technique minimized dependency, and the possiblity of addiction to amobarbital interviews permitted more active patient therapy involvement, and set clear-cut goals and expectations for improvement before further amobarbital interviews could be conducted.

    This descriptive qualitative study had the following objectives: identify the content and structure of social representations of quality of life and AIDS for persons living with the disease and analyze the structural relations between such representations. The sample included 103 persons with HIV in a municipality (county) in northern Rio de Janeiro State, Brazil. The methodology used free and hierarchical recall of words for the inductive terms "AIDS" and "quality of life for persons with AIDS", with analysis by the EVOC software. The probable core representation of AIDS was identified as: prejudice, treatment, family, and medications, with the same components identified for quality of life, plus healthy diet and work. We thus elaborated the hypothesis of joint, coordinated representational interaction, fitting the representations together, with implications for the symbolic grasp and quality of life for persons living with HIV. The findings provide backing for collective and individual health approaches to improve quality of life in this group. PMID:25760170

    Models of dream analysis either assume a continuum of waking and dreaming or the existence of two dissociated realities. Both approaches rely on different methodology. Whereas continuity models are based on content analysis, discontinuity models use a structural approach. In our study, we applied both methods to test specific hypotheses about continuity or discontinuity. We contrasted dream reports of congenitally deaf-mute and congenitally paraplegic individuals with those of non-handicapped controls. Continuity theory would predict that either the deficit itself or compensatory experiences would surface in the dream narrative. We found that dream form and content of sensorially limited persons was indifferent from those of non-handicapped controls. Surprisingly, perceptual representations, even of modalities not experienced during waking, were quite common in the dream reports of our handicapped subjects. Results are discussed with respect to feedforward mechanisms and protoconsciousness theory of dreaming. PMID:21147002

    The authors used the frameworks of reciprocal determinism and occupational socialization to study the effects of work characteristics (consisting of control and complexity of work) on personal initiative (PI)--mediated by control orientation (a 2nd-order factor consisting of control aspiration, perceived opportunity for control, and self-efficacy) and the reciprocal effects of PI on changes in work characteristics. They applied structural equation modeling to a longitudinal study with 4 measurement waves (N = 268) in a transitional economy: East Germany. Results confirm the model plus 1 additional, nonhypothesized effect. Work characteristics had a synchronous effect on PI via control orientation (full mediation). There were also effects of control orientation and of PI on later changes in work characteristics: As predicted, PI functioned as partial mediator, changing work characteristics in the long term (reciprocal effect); unexpectedly, there was a 2nd reciprocal effect of an additional lagged partial mediation of control orientation on later work characteristics.

    A finite element based programming system for minimum weight design of a truss-type structure subjected to displacement, stress, and lower and upper bounds on design variables is presented. The programming system consists of a number of independent processors, each performing a specific task. These processors, however, are interfaced through a well-organized data base, thus making the tasks of modifying, updating, or expanding the programming system much easier in a friendly environment provided by many inexpensive personal computers. The proposed software can be viewed as an important step in achieving a 'dummy' finite element for optimization. The programming system has been implemented on both large and small computers (such as VAX, CYBER, IBM-PC, and APPLE) although the focus is on the latter. Examples are presented to demonstrate the capabilities of the code. The present programming system can be used stand-alone or as part of the multilevel decomposition procedure to obtain optimum design for very large scale structural systems. Furthermore, other related research areas such as developing optimization algorithms (or in the larger level: a structural synthesis program) for future trends in using parallel computers may also benefit from this study.

    Objectives: Limited human resources are widely recognised as a barrier to achieve health-related Millennium Development Goals. Availability of medical supplies and suitably trained health personnel are crucial to ensuring a well-functioning medical supply system. The objective of this paper is to identify the factors which influence the availability of medical supplies within the health facilities of Vanuatu. Methods: A qualitative triangulated strategy using semi-structured interviews, observational workplace surveys and semi-structured focus groups was developed. This research was approved by the Human Ethics Committee of the University of Canberra and was funded through a direct grant from the United Nations Population Fund Suva, Pacific sub regional office. Results: During two weeks of data collection, 21 interviews were conducted, observational workplace surveys were completed in 19 facilities and 22 personnel participated in three focus groups across three provinces. The interviewees had a wide range of primary professional groupings and were representative of the Vanuatu health workforce. A complex array of medical supply issues are described from within the three tiered structure of the medical supply system. Conclusion: The results of this research have further informed our understanding of the competencies required by healthcare personnel to conduct medical supply management activities effectively in Pacific Island countries. As a result of this research, a platform is provided for the government of Vanuatu to engage development partners to work toward a sustainable medical supply system. PMID:23093895

  1. Personality and support for universal human rights: a review and test of a structural model.

    PubMed

    McFarland, Sam

    2010-12-01

    All individual differences that predict support for international human rights are first reviewed: support for human rights is linked most positively to "globalism" (other international and environmental concerns), "identification with all humanity," principled moral reasoning, benevolence, and dispositional empathy. It is related most negatively to ethnocentrism and its root dispositions, the social dominance orientation, and authoritarianism. Other correlates are also noted. Secondly, a structural model of the effects of authoritarianism, social dominance, ethnocentrism and identification with all humanity upon commitment to human rights is presented and tested. Across 2 studies (Study 1, N=218 nonstudent adults; Study 2, N=102 university students), ethnocentrism and identification with all humanity directly predicted human rights commitment. The effects of authoritarianism upon this commitment were fully mediated through enhanced ethnocentrism and reduced identification with all humanity. The effects of social dominance were similar, but its direct effect upon human rights commitment remained significant and was not, in the second study, mediated by reduced dispositional empathy.

    The staff of the International Commission on Missing Persons (ICMP) is attempting to undertake the largest mass human identification effort in history. Through the generosity of numerous governmental and private corporations the ICMP has established or is currently establishing a strong network of political allies, family outreach centers, and DNA laboratories throughout the former Yugoslavia. Furthermore, the ICMP is currently working to streamline current technology as well as employ new technology in its efforts to assist in identifying missing individuals. ICMP will continue to act as a link between the family associations in the region and will synchronize the work of the DNA identification process in the countries affected by the war in the regions of the former Yugoslavia. In the longer term, ICMP seeks to contribute to the closure of the missing persons issue, to raise awareness of the human dimension of the missing persons tragedy, and to preserve a shared and common memory of the missing in the former Yugoslavia.

    Rotations of 1 to 12 factors were compared by Goldberg's “bass-ackward” method, with or without initially holding constant one or more principal components. Two sets of data were employed: ratings by 320 undergraduates using 435 personality-descriptive adjectives, and 512 Oregon community members' responses to 184 scales from 8 personality inventories. Holding constant none or one or three initial factors made relatively little difference to the resulting structure. On the whole, that structure was not strongly hierarchical: allowing an additional dimension usually resulted in a new substantive dimension rather than in the splitting of an old one. PMID:25197156

  7. Design of RTPV generators integrated with new millennium spacecraft for outer solar system

    1996-03-01

    The National Aeronautics and Space Administration's recently inaugurated New Millennium program, with its emphasis on miniaturized spacecraft, has generated interest in a low-power (10- to 30-watt), low-mass, high-efficiency RTPV (Radioisotope Thermophotovoltaic) power system. This led to a Department of Energy (DOE)-sponsored design study of such a system, which was assigned to OSC (formerly Fairchild) personnel, who have been conducting similar studies of a 75-watt RTPV system with very encouraging results. The 75-watt design employed two 250-watt General Purpose Heat Source (GPHS) modules that DOE had previously developed and safety-qualified for various space missions. These modules were too large for the small RTPVs described in this paper. To minimize the need for new development and safety verification studies, OSC generated derivative designs for 125-watt and 62.5-watt heat source modules containing identical fuel pellets, clads, impact shell, and thermal insulation. OSC also generated a novel heat source support scheme to reduce the heat losses through the structural supports, and a new and much simpler radiator structure, employing no honeycombs or heat pipes. OSC's previous RTPV study had been based on the use of GaSb PV cells and spectrally selective IR filters that had been partially developed and characterized by Boeing (now EDTEK) personnel, who had supplied us with spectral data on filter reflectivities and cell quantum efficiencies. Because of the very encouraging results of our system design studies, OSC in the fall of 1994 initiated an experimental program at EDTEK to develop improved filters and cells, to demonstrate how much improvement can actually be achieved. OSC requested that first priority be given to filter improvements, because our system studies indicated that improved filters would have a much greater effect on system performance than cell improvements. By September 1995 EDTEK had achieved about 94% of the filter performance

    Member countries of the World Health Organization (WHO) met in Alma Ata (8-12 September 1978) to define and advocate the implementation of primary health care (PHC) worldwide, above all, in developing countries, which had a real need to review their strategies for meeting the health needs of their populations. They did not suspect that 20 years later the vision they displayed would remain undeniably relevant. Here we examine the similarities and points of convergence of their declaration about PHC with the Millennium Development Goals that seek today to reduce poverty across the world. An exhaustive and analytic literature review was conducted to collect those similarities. Further analysis of the definitions, objectives, principles and recommendations of the Alma Ata Declaration and the Millennium Declaration reveals multiple dependencies and fundamental points of similarity between these two representations. Almost all states have pledged to achieve the eight MDG by 2015: to eradicate extreme poverty and hunger, achieve universal primary education, promote gender equality and empower women, reduce child mortality, improve maternal health, combat HIV/AIDS, malaria and other diseases, ensure environmental sustainability, and develop a global partnership for development. The Alma Ata conference defined primary health care as essential health care, based on practical methods and techniques that are both scientifically sound and socially acceptable, universally accessible to all individuals and all families of the community, through their full participation and at a cost that the community and countries can afford at all stages of their development in the spirit of self-reliance and self-determination. It is an integral part of economic and social development. The following principles are involved in the achievement of both primary health care and the MDG: social equity, community participation, and intersectorality. Public health is an essential condition of poverty

    To predict the future of Celestial Mechanics and to investigate unsolved problems for the next millennium contradicts the nature of our field of science which is based on non-integrable and transcendental equations with short time predictability. The reliability and predictability in our field depend on several factors, most of them unpredictable. Numerical predictions depend on the development of computer technology, which is itself not predictable. New analytical approaches call for the genius of Newton. We must realize that between Ptolemaeus (100 178) and Copernicus (1473 1543) our field received little attention. Between 1700 and 1800 the explosion occurred (Newton, Euler, Laplace, Lagrange and Gauss) followed by the period of 1800 1900 associated with Hamilton, Hill, Jacobi, Poincaré and Tisserand. Can we expect anyone to make similar contributions in the next 1000 years? The entrance and emphasis of probability in our field certainly will continue. Speaking about bounds of trajectories instead of individual orbits gains significant popularity. Theory of stability and chaos are expected to receive more and more attention together with Poincare's conjectures concerning the denseness of periodic orbits in the set of bounded orbits. Planetary computations for long time have shown considerable advances, partly due to computer advances as well as the selection of the proper formulation of the problems. The preparation of “exact” short time ephemerides and qualitative long time predictions require initial conditions with small observational errors, the use of proper models (including relativity effects and non-conservative forces) and the use of correct values of astronomical constants. The results of such calculations in the future should include approximate estimations of errors in the outcome. The observations and orbital calculations of Earth-crossing asteroids should receive special attention along with development of various techniques of space dynamics

  10. Interpersonal Perceptions of the Five-Factor Model of Personality: An Examination Using the Structural Summary Method for Circumplex Data.

    Research investigating the structural convergence of the Interpersonal Circumplex (IPC; Wiggins, 1979, 1995) with the Five Factor Model (FFM; Costa & McCrae, 1992) of personality has predominantly focused on the traits of Agreeableness and Extraversion. The characteristics of the other three FFM traits: Neuroticism, Openness, and Conscientiousness are often regarded as largely intrapsychic. This study assessed interpersonal perceptions of the FFM traits emphasized in target descriptions by examining respondents' ratings of a target's interpersonal style. In an attempt to isolate the interpersonal aspects of each FFM trait, descriptions of fictional individuals were created that contained information relevant to being extremely high or low on a single FFM trait. Female and male versions were created to ensure gender has no effect on the interpersonal perceptions of the fictitious individual. The 462 participants received a paragraph description of an individual and were instructed to rate the individual on the Interpersonal Adjective Scales (IAS; Wiggins, 1995) based on the target description. Their responses were evaluated using Gurtman's (1994) structural summary approach to describe circumplex data. Based on the results for Extraversion and Agreeableness targets, the descriptions appear to be a valid approach in eliciting previous empirically supported interpersonal perceptions of the FFM. A 5 (Trait) x 2 (Polarity) x 2 (Gender) MANOVA found significant main effects for trait and polarity, and a significant trait x polarity interaction. No gender differences were found. The consistent fit of ratings data to the circumplexical cosine curve examined within the structural summaries supports propositions by several researchers that all FFM traits contain agentic and communal qualities as measured by the IAS.

    The Indian Ocean Dipole (IOD) climate mode interacts with the El Niño-Southern Oscillation and Asian monsoon systems to drive climatic extremes around the Indian Ocean region. Coral reconstructions of the interannual variability of the IOD since the 1850s show an intensification in the frequency and strength of the positive phase of the IOD in recent decades, as well as strengthening of the interconnection between the IOD and Asian monsoon systems. Reconstructions of the mean climate state across the tropical Indian Ocean since the mid-Holocene also demonstrate the dynamic nature of the mean configuration of tropical Indian Ocean climate, suggesting that the IOD variability and interactions observed on interannual time scales may also persist over century to millennial scales. Here we present new oxygen isotope (δ18O) records from modern Porites corals collected on a transect along Java-Sumatra coasts. These corals, located within the IOD upwelling zone, are used to identify the location where optimum information about the occurrence and magnitude of positive IOD events can be gained from single corals. Precisely-dated fossil corals from this location of optimum IOD variability are then used to reconstruct highly resolved windows of IOD variability during the last millennium, including intervals corresponding to the northern hemisphere Little Ice Age and Medieval Warm Period.

    The Millennium Ecosystem Assessment (MA) introduced a new framework for analyzing social–ecological systems that has had wide influence in the policy and scientific communities. Studies after the MA are taking up new challenges in the basic science needed to assess, project, and manage flows of ecosystem services and effects on human well-being. Yet, our ability to draw general conclusions remains limited by focus on discipline-bound sectors of the full social–ecological system. At the same time, some polices and practices intended to improve ecosystem services and human well-being are based on untested assumptions and sparse information. The people who are affected and those who provide resources are increasingly asking for evidence that interventions improve ecosystem services and human well-being. New research is needed that considers the full ensemble of processes and feedbacks, for a range of biophysical and social systems, to better understand and manage the dynamics of the relationship between humans and the ecosystems on which they rely. Such research will expand the capacity to address fundamental questions about complex social–ecological systems while evaluating assumptions of policies and practices intended to advance human well-being through improved ecosystem services.

    With the advent of the new Millennium, Picture Archive and Communications System (PACS) technology has matured to levels sufficient to support open systems based, regional implementations. This shifts the site-centric PACS paradigm into broader scale, impacting facilities, workflow, business plans and ultimately patient care on a regional basis. Prudent and effective management of a regional implementation is critical to overall project success based upon a number of competing influences fundamental to the PACS including network infrastructure, clinical workflow, acquisition modalities, planning documentation, site preparation, acceptance testing, project communication, interface integration issues, etc. Risk mitigation is possible by understanding and managing the interrelationships of these influences through a phased approach with embedded management controls. The overall phases of regional implementation are not unlike site-centric implementations, consisting of Discovery, Planning, Preparation, Installation; Acceptance and Warranty/Maintenance; however, details which manifest over time are what provide significant management challenges. When balanced using a culturally reinforced policy of open, frequent and hands-on communication, regional PACS projects can be successfully implemented maintaining budget, schedule and scope thresholds.

    The Millennium Development Goals (MDGs) are eight international development goals to be achieved by 2015 addressing poverty, hunger, maternal and child mortality, communicable disease, education, gender inequality, environmental damage and the global partnership. Most activities worldwide have focused on maternal and child health and communicable diseases, while less attention has been paid to environmental sustainability and the development of a global partnership. Up to now, several targets have been at least partially achieved: hunger reduction is on track, poverty has been reduced by half, living conditions of 200 million deprived people enhanced, maternal and child mortality as well as communicable diseases diminished and education improved. Nevertheless, some goals will not be met, particularly in the poorest regions, due to different challenges (e.g. the lack of synergies among the goals, the economic crisis, etc.). The post-2015 agenda is now under discussion. The new targets, whatever they will be called, should reflect today's political situation, health and environmental challenges, and an all-inclusive, intersectoral and accountable approach should be adopted.

    The first decade of the 21st century has seen significant development in the production of paleo proxies for the Asian monsoon, exemplified by the Monsoon Asian Drought Atlas that was comprised of more than 300 tree ring chronologies. Noteworthy among them is the Vietnamese cypress tree-ring record which reveals that the two worst droughts of the past 7 centuries, each more than a decade in length, coincided with the demise of the Khmer civilization at Angkor in the early 15th century CE. The 18th century was nearly as tumultuous a period across Southeast Asia, where several polities fell against a backdrop of epic decadal-scale droughts. At this time all of the region's charter states saw rapid realignment in the face of drought, famine, disease and a raft of related and unrelated social issues. Several other droughts, some more extreme but of lesser duration, punctuate the past millennium, but appear to have had little societal impact. Historical documentation is being used not only to provide corroborative evidence of tree-ring reconstructed climate extremes, but to attempt to understand the dynamics of the coupled human-natural systems involved, and to define what kinds of thresholds need to be reached before societies respond. This paleo perspective can assist our analyses of the role of climate extremes in the collapse or disruption of regional societies, a subject of increasing concern given the uncertainties surrounding projections for future climate across the highly populated areas of Asia.

    2012-03-01

    This report covers a millennium, from year 1000 when Sweden had only 0.4 million people until today's 9.4 million. In the 13th century, the first Swedish legal text about the mentally ill and the first hospital to treat them are documented. Control, care and cure of the ill have been shaped by social and cultural changes from time to time, e.g. King Gustav Vasa introduced a paradigm shift of care after the Reformation, when he altered Catholic buildings into state hospitals. He also ordered that medical texts should no longer be written in Latin but in Swedish. The first book dealing with mental illnesses was published in 1578. Laypersons ran the mental hospitals for centuries until the medical perspective and doctors were engaged in the 1800 s. To advance the hospital doctors' competence and skill, a Swedish Psychiatric Association was established in 1905. Severely psychotic patients could not be effectively treated until the introduction of chlorpromazine in the 1950s and there is still no cure available. Following the deinstitutionalization, from more than 35,000 beds 50 years ago down to about 4500 today, the request for outpatient treatment increased. Mandatory training in psychotherapies for all psychiatrists started in the 1970s. A major "psychiatry reform", with the hope of improving the situation for the mentally ill, and to reduce the stigma, was introduced in Sweden in 1995. The historic long-term effect of the reform cannot yet be fully evaluated. PMID:21770823

Replacement items in the PI-3 showed on average stronger item-total correlations and slightly improved facet reliabilities compared with the NEO-PI-R in both English- and non-English-speaking samples. NEO-PI-3 replacement items did not substantially affect scale means compared with the original scales. Analyses across and within cultures confirmed the intended factor structure of both versions when used to describe young adolescents. The authors discuss implications of these cross-cultural findings for the advancement of studies in adolescence and personality development across the lifespan. PMID:19419953

    The current study examines the relations among contemporary models of pathological and normal range personality traits. Specifically, we report on (a) conjoint exploratory factor analyses of the Computerized Adaptive Test of Personality Disorder static form (CAT-PD-SF) with the Personality Inventory for the DSM-5 (PID-5; Krueger et al., 2012) and NEO Personality Inventory-3 First Half (NEI-PI-3FH; McCrae & Costa, 2007), and (b) unfolding hierarchical analyses of the three measures in a large general psychiatric outpatient sample (N = 628; 64% Female). A five-factor solution provided conceptually coherent alignment among the CAT-PD-SF, PID-5, and NEO-PI-3FH scales. Hierarchical solutions suggested that higher-order factors bear strong resemblance to dimensions that emerge from structural models of psychopathology (e.g., Internalizing and Externalizing spectra). These results demonstrate that the CAT-PD-SF adheres to the consensual structure of broad trait domains at the five-factor level. Additionally, patterns of scale loadings further inform questions of structure and bipolarity of facet and domain level constructs. Finally, hierarchical analyses strengthen the argument for using broad dimensions that span normative and pathological functioning to scaffold a quantitatively derived phenotypic structure of psychopathology to orient future research on explanatory, etiological, and maintenance mechanisms.

    This study examined the factorial structure and diagnostic efficiency of the DSM-IV criteria for avoidant personality disorder (AVPD). Two hundred and twenty-eight consecutive outpatients (181 females and 47 males) with a primary diagnosis of binge eating disorder were reliably assessed with diagnostic interviews. Internal consistency of AVPD criteria was good, as suggested by coefficient alpha of 0.87, the pattern of inter-item correlations (range 0.41 to 0.64), and the lack of changes in alpha if any criteria are deleted. Exploratory factor analysis revealed a one-factor solution (56% of variance) supporting the unidimensionality of the AVPD criteria. Diagnostic efficiency indices (conditional probabilities, total predictive power, and kappa coefficients) were calculated for each AVPD criterion, for the entire study group and separately by gender. Overall, the best inclusion criterion was 'fears being ridiculed,' which was also the best predictor overall. These psychometric findings did not differ by gender. The findings support certain important aspects of the AVPD diagnosis. PMID:15350855

    The efficacy and mechanisms of therapeutic action are largely described by atomic bonds and interactions local to drug binding sites. Here we introduce global connectivity analysis as a high-throughput computational assay of therapeutic action - inspired by the Google page rank algorithm that unearths most ``globally connected'' websites from the information-dense world wide web (WWW). We execute short timescale (30 ps) molecular dynamics simulations with high sampling frequency (0.01 ps), to identify amino acid residue hubs whose global connectivity dynamics are characteristic of the ligand or mutation associated with the target protein. We find that unexpected allosteric hubs - up to 20Å from the ATP binding site, but within 5Å of the phosphorylation site - encode the Gibbs free energy of inhibition (ΔGinhibition) for select protein kinase-targeted cancer therapeutics. We further find that clinically relevant somatic cancer mutations implicated in both drug resistance and personalized drug sensitivity can be predicted in a high-throughput fashion. Our results establish global connectivity analysis as a potent assay of protein functional modulation. This sets the stage for unearthing disease-causal exome mutations and motivates forecast of clinical drug response on a patient-by-patient basis. We suggest incorporation of structure-guided genetic inference assays into pharmaceutical and healthcare Oncology workflows.

    A process involving the use of membrane bioreactor seeded with aerobic granular sludge (GMBR) was applied to the treatment of sewage containing pharmaceuticals and personal care products (PPCPs). The removal effects of five kinds of medicines in the reactor were investigated, and the microbial communities were constructed by polymerase chain reaction and denaturing gradient gel electrophoresis. We also determined the effects of different sludge retention and hydraulic retention times (SRT and HRT, respectively) and influent organic loading on GMBR's efficiency in processing sewage containing PPCPs. The removal effects of the GMBR on five PPCPs varied. Using the GMBR, the removal rates of prednisolone, naproxen and norfloxacin were 98.56, 84.02 and 87.85%, respectively. The removal rates of sulfamethoxazole and ibuprofen were 77.83 and 63.32%, respectively. In the system, PPCP drugs had relatively less effect on microbial diversity. A certain succession was observed in the structural variation of microbial species in the GMBR. Microorganisms that can degrade PPCPs gradually accumulated, and antibiotic-resistant microorganisms, such as Firmicutes sp., Aeromonas sp. and Nitrospira sp., served a key function in the treatment of sewage containing antibiotics. Long SRT and HRT during the GMBR process can facilitate the removal of most PPCPs. The system efficiently removed PPCPs at high influent organic loading. PMID:25099174

    Dementia is a global health issue and the effects on caregivers are substantial. The study aimed to examine the associations of burden, coping, self-efficacy with quality of life among family caregivers of persons with dementia in Singapore. Structured interviews were conducted in a convenience sample of 84 family caregivers caring and seeking clinical care for the persons with dementia in an outpatient clinic of a public hospital in Singapore. The outcome measures included the Family Burden Interview Schedule, Family Crisis Oriented Personal Evaluation Scale, General Perceived Self-Efficacy Scale, and World Health Organization Quality of Life Scale - Brief Version. In general, significant correlations were observed between the quality of life scores with coping strategy and family burden scores, but not between the coping strategy and family burden scores. Compared to demographic factors such as caregiver age and household income, psychosocial factors including family burden, coping strategies, and self-efficacy demonstrated greater association with quality of life in the participants. However, the dynamics of these associations will change with an increasing population of persons with dementia, decreasing nuclear family size, and predicted changes in family living arrangements for the persons with dementia in future. As such, it necessitates continuous study examining the needs and concerns of family caregivers and the relevance of ongoing interventions specific to caregivers of persons with dementia.

    An interview schedule was used to record the personality traits of 130 psychiatric patients, 65 with a primary clinical diagnosis of personality disorder and 65 with other diagnoses. The results were analysed by factor analysis and three types of cluster analysis. Factor analysis showed a similar structure of personality variables in both groups of patients, supporting the notion that personality disorders differ only in degree from the personalities of other psychiatric patients. Cluster analysis revealed five discrete categories; sociopathic, passive-dependent, anankastic, schizoid and a non-personality-disordered group. Of all the personality-disordered patients 63 per cent fell into the passive-dependent or sociopathic category. The results suggest that the current classification of personality disorder could be simplified. PMID:497619

    This presentation reviews the activities of the New Millennium Program (NMP) in validating advanced technologies for space missions. The focus of these breakthrough technologies are to enable new capabilities to fulfill the science needs, while reducing costs of future missions. There is a broad spectrum of NMP partners, including government agencies, universities and private industry. The DS-1 was launched on October 24, 1998. Amongst the technologies validated by the NMP on DS-1 are: a Low Power Electronics Experiment, the Power Activation and Switching Module, Multi-Functional Structures. The first two of these technologies are operational and the data analysis is still ongoing. The third program is also operational, and its performance parameters have been verified. The second program, DS-2, was launched January 3 1999. It is expected to impact near Mars southern polar region on 3 December 1999. The technologies used on this mission awaiting validation are an advanced microcontroller, a power microelectronics unit, an evolved water experiment and soil thermal conductivity experiment, Lithium-Thionyl Chloride batteries, the flexible cable interconnect, aeroshell/entry system, and a compact telecom system. EO-1 on schedule for launch in December 1999 carries several technologies to be validated. Amongst these are: a Carbon-Carbon Radiator, an X-band Phased Array Antenna, a pulsed plasma thruster, a wideband advanced recorder processor, an atmospheric corrector, lightweight flexible solar arrays, Advanced Land Imager and the Hyperion instrument

  7. Downscaling GCM-simulated precipitation for the last millennium

    2014-05-01

    Climate variability in the pre-instrumental period can be estimated either from climate proxy data or from numerical simulations. Both approaches still have considerable uncertainties and consistency tests are crucial for identifying robust features. One of the problems when comparing simulations with proxy-based reconstructions are potential scale mismatches. If the proxy-based reconstructions represent regional climate a direct comparison with simulated variables from global climate models, which in palaeoclimate applications are run with coarse resolutions, can lead to misleading results for two reasons: (i) the climate model might be biased even on large spatial scales, and (ii) small-scale spatial variability cannot be represented by the climate model. This problem can be expected to be particularly relevant for precipitation because of its high spatial variability. One way of addressing this problem is by applying downscaling techniques to the simulations. We have applied a statistical downscaling and correction method to precipitation from a simulation for the last millennium with the MPI for Meteorology Earth System Model, which uses ECHAM5-T31 as the atmosphere component. Our downscaling method, which is based on model output statistics (MOS), has been shown to outperform more standard (so-called perfect-prog) statistical downscaling methods when applied to simulated precipitation from the second half of the twentieth century, but it has not yet been applied to palaeoclimate simulations. Our aim is two-fold: to assess (a) whether downscaling using MOS yields additional information about long-term changes in regional climate and (b) to what extent the downscaled simulations may be in greater agreement with proxy-based reconstructions than raw model output. Two MOS downscaling methods, based on local scaling and principal component regression, are calibrated 'event-wise' (i.e. between contemporaneous sequences of simulated and observed events) using

  9. Primary surgery for differentiated thyroid cancer in the new millennium.

    PubMed

    Dralle, H; Machens, A

    2012-01-01

    Differentiated thyroid cancers (DTC) are malignancies of follicular cell derivation. Histopathologically and oncologically, DTC fall into two broad tumor categories: papillary (PTC) and follicular thyroid cancer (FTC). These major tumor categories, based on clinical manifestation and biological behavior, are further subdivided into low-risk [papillary microcarcinoma (mPTC); minimally invasive follicular cancer (MIFTC)] and high-risk DTC [PTC>1 cm or metastatic; MIFTC with histopathological angioinvasion; widely invasive FTC (WIFTC)]. Recently, a surgical approach has been adopted that differentiates between low-risk and high-risk DTC. The rationale behind this new concept is to better balance oncologic risk (high vs low) with the surgical morbidity attendant to the procedure (recurrent laryngeal nerve palsy and hypoparathyroidism). This surgical risk is larger with routine total thyroidectomy (TT) and central node dissection (CND) than with less than TT or TT without CND.Whereas TT with CND remains the treatment of choice for high-risk DTC with metastases, the extent of thyroid resection and lymph node dissection can be reduced in low-risk PTC and FTC without demonstrable loss of oncological benefit. In the new millennium, the surgical approach to DTC, especially low-risk PTC and FTC, has undergone considerable change, resulting in less extensive procedures. This risk-adapted strategy relies not only on the skillful histopathologic detection of multifocality in PTC and vascular invasion in MIFTC, but likewise necessitates diligent follow-up to spot and adequately treat local recurrences and distant metastases as they become clinically apparent.

    In many countries, governments pursue a policy of offering persons with disabilities greater opportunities for participation in society, based on the assumption that this will also improve their subjective well-being. Currently, however, it is not known whether this assumption is valid. In this study we relate the objective participation and the subjective well-being aspects of both disabled and non-disabled persons to an array of social and health-related determinants. Linear structural equation modelling of data of a sample selection of the Dutch population is analysed. The sample size is 5,826, including 642 respondents with physical disabilities. In terms of objective participation, the persons with disabilities are at a greater disadvantage as regards labour participation than is the case for social and cultural participation. When it comes to subjective well-being, we find that the persons with disabilities are more likely to lag behind in perceived physical health than in mental health and happiness. In a multivariate model relating objective participation to subjective health and happiness, correlations are much weaker than expected. It is striking to find that participation, perceived health and happiness are much less closely related than is often assumed. Their determinants differ widely in nature and strength. The empirical model leads to rejection of the hypothesis that higher participation by the persons with disabilities is associated with higher subjective well-being. PMID:17268932

    The Mediterranean region is a climatic transitional zone between the subtropical/monsoon regime and the temperate westerlies and is subject to forces acting upon the global climate system. Much knowledge about its climate over the last millennium is derived from terrestrial records, whereas changes in sea surface temperatures (SSTs) and in the dissolved inorganic carbon pool (DIC) are poorly known. We present continuous high-resolution reconstructions of SST and δ13CDIC in the eastern Mediterranean (EM) Sea, as inferred from oxygen and carbon isotope records from the skeletons of the reef builder gastropod Dendropoma sp. Spanning the past millennium, the SST reconstruction reveals a 250 year persistent warming trend during which the twentieth century was the warmest on record. Coupled with a distinct trend of 13CDIC depletion and superimposed upon decreased primary production, this climate reconstruction reflects a new state of the EM over the Anthropocene era that exceeds the natural variability of the last millennium.

    NASA's New Millennium Program (NMP) is designed to develop, test, and flight validate new, advanced technologies for planetary and Earth exploration missions, using a series of low cost spacecraft. Two of NMP's current missions include encounters with comets and asteroids. The Deep Space 1 mission was launched on October 24, 1998 and will fly by asteroid 1992 KD on July 29, 1999, and possibly Comet Wilson-Harrington and/or Comet Borrelly in 2001. The Space Technology 4/Champollion mission will be launched in April, 2003 and will rendezvous with, orbit and land on periodic Comet Tempel 1 in 2006. ST-4/Champollion is a joint project with CNES, the French space agency. The DS-1 mission is going well since launch and has already validated several major technologies, including solar electric propulsion (SEP), solar concentrator arrays, a small deep space transponder, and autonomous navigation. The spacecraft carries two scientific instruments: MICAS, a combined visible camera and UV and IR spectrometers, and PEPE, an ion and electron spectrometer. Testing of the science instruments is ongoing. Following the asteroid encounter in July, 1999, DS-1 will go on to encounters with one or both comets if NASA approves funding for an extended mission. The ST-4/Champollion mission will use an advanced, multi-engine SEP system to effect a rendezvous with Comet P/Tempel 1 in February, 2006, after a flight time of 2.8 years. After orbiting the comet for several months in order to map its surface and determine its gravity field, ST-4/Chainpollion will descend to the comet's surface and will anchor itself with a 3-meter long harpoon. Scientific experiments include narrow and wide angle cameras for orbital mapping, panoramic and near-field cameras for landing site mapping, a gas chromatograph/mass spectrometer, a combined microscope and infrared spectrometer, and physical properties probes. Cometary samples will be obtained from depths up to 1.4 meters. The spacecraft is solar powered

    2016-04-01

    Climate has varied considerably during the late Holocene and these changes left their traces in history (Medieval Climate Optimum, Little Ice Age). However, the relative magnitude of natural fluctuations due to internal variability of the Earth's climate system and to variations in the external forcing and the present global warming, attributed to anthropogenic greenhouse gases, is still under debate. Investigating the response to (mainly) natural forcing under climatic background conditions not too different from today is crucial for an improved understanding of climate variability, circulation, and regional connectivity. Simulations over the last millennium (LM) allow assessing climate variability on decadal and longer scales and provide information on predictability under forced and unforced conditions. In providing in-depth model evaluation with respect to observations and paleoclimatic reconstructions, LM simulations serve to understand origins and consequences of systematic model biases. PMIP4 Tier-1 includes the standard LM simulation covering 850 to 1849 CE and a subsequent "historical" (1850 - 2010 CE) experiment as a minimum requirement. In addition to changes in Earth's orbit and greenhouse gas concentrations, the models are forced by variations in solar irradiance, volcanic aerosol load, and anthropogenic land-cover. As part of Tier-2, the modeling groups are asked to provide additional simulations in the form of ensembles, single forcing experiments, as well as sensitivity runs using alternative forcing combinations. The extension of the simulations to cover the complete last two millennia (0 CE to present) is also part of Tier-2. We describe the experimental design of the LM simulations and discuss the protocol on new forcing and boundary conditions. We discuss recent advances in the reconstruction of solar, volcanic, and land-cover changes and their implementation in the CMIP6 models. PMIP4 aims to provide forcing datasets that are consistent with

    To better understand human and chimpanzee personality evolution, we obtained trait ratings of personality for 154 captive bonobos (~80% of the U.S. and European population). We found factors that we labeled Assertiveness, Conscientiousness, Openness, Agreeableness, Attentiveness, and Extraversion. The interrater reliabilities and test-retest reliabilities for these factors were comparable to those found in humans and other species. Using orthogonal targeted Procrustes rotations, we compared the bonobo dimensions with those of three samples of captive chimpanzees. Overall congruence coefficients indicated a fair degree of similarity; at the factor level, there was good evidence for Assertiveness, Conscientiousness, Openness, and Agreeableness in the chimpanzee samples; evidence for Attentiveness and Extraversion was poor. These findings suggest that, as expected given their close phylogenetic relationship, bonobo personality structure resembles chimpanzee personality structure in some respects. However, divergent evolution, perhaps as a result of socioecological differences between bonobos and chimpanzees, also appears to have shaped personality structure in these species. PMID:26209530

    In the prehistoric green Sahara of Holocene North Africa-in contrast to the Neolithic of Europe and Eurasia-a reliance on cattle, sheep and goats emerged as a stable and widespread way of life, long before the first evidence for domesticated plants or settled village farming communities. The remarkable rock art found widely across the region depicts cattle herding among early Saharan pastoral groups, and includes rare scenes of milking; however, these images can rarely be reliably dated. Although the faunal evidence provides further confirmation of the importance of cattle and other domesticates, the scarcity of cattle bones makes it impossible to ascertain herd structures via kill-off patterns, thereby precluding interpretations of whether dairying was practiced. Because pottery production begins early in northern Africa the potential exists to investigate diet and subsistence practices using molecular and isotopic analyses of absorbed food residues. This approach has been successful in determining the chronology of dairying beginning in the 'Fertile Crescent' of the Near East and its spread across Europe. Here we report the first unequivocal chemical evidence, based on the δ(13)C and Δ(13)C values of the major alkanoic acids of milk fat, for the adoption of dairying practices by prehistoric Saharan African people in the fifth millennium bc. Interpretations are supported by a new database of modern ruminant animal fats collected from Africa. These findings confirm the importance of 'lifetime products', such as milk, in early Saharan pastoralism, and provide an evolutionary context for the emergence of lactase persistence in Africa.

    Mwendera, E. J.

    An assessment of rural water supply and sanitation (RWSS) coverage in Swaziland was conducted in 2004/2005 as part of the Rural Water Supply and Sanitation Initiative (RWSSI). The initiative was developed by the African Development Bank with the aim of implementing it in the Regional Member Countries (RMCs), including Swaziland. Information on the RWSS sector programmes, costs, financial requirements and other related activities was obtained from a wide range of national documents, including sector papers and project files and progress reports. Interviews were held with staff from the central offices and field stations of Government of Swaziland (GOS) ministries and departments, non-governmental organizations (NGOs), bilateral and multilateral external support agencies, and private sector individuals and firms with some connection to the sector and/or its programmes. The assessment also involved field visits to various regions in order to obtain first hand information about the various technologies and institutional structures used in the provision of water supplies and sanitation services in the rural areas of the country. The results showed that the RWSS sector has made significant progress towards meeting the national targets of providing water and sanitation to the entire rural population by the year 2022. The assessment indicated that rural water supply coverage was 56% in 2004 while sanitation coverage was 63% in the same year. The results showed that there is some decline in the incidence of water-related diseases, such as diarrhoeal diseases, probably due to improved water supply and sanitation coverage. The study also showed that, with adequate financial resources, Swaziland is likely to achieve 100% coverage of both water supply and sanitation by the year 2022. It was concluded that in achieving its own national goals Swaziland will exceed the Millennium Development Goals (MDGs). However, such achievement is subject to adequate financial resources being

    Currently, little is known on how volcanic eruptions impact large-scale climate phenomena such as paleo-ITCZ position or South American summer monsoon behavior. In this paper, an analysis of observations and model simulations is employed to assess the influence of large volcanic eruptions on the climate of South America. This problem is considered both for historically recent volcanic episodes, for which more comprehensive global observations exist, as well as reconstructed volcanic events for the period 850 C.E. to present that are incorporated into the NASA GISS ModelE2-R simulation of the Last Millennium. An advantage of this model is its ability to explicitly track water isotopologues throughout the hydrologic cycle and simulating the isotopic imprint following a large eruption. This effectively removes a degree of uncertainty associated with error-prone conversion of isotopic signals into climate variables, and allows for a direct comparison between GISS simulations and paleoclimate proxy archives. Our analysis reveals that both precipitation and oxygen isotope variability respond with a distinct seasonal and spatial structure across South America following an eruption. During austral winter, the heavy oxygen isotope in precipitation is enriched, likely due to reduced moisture convergence in the ITCZ domain and reduced rainfall over northern South America. During austral summer, however, precipitation is depleted in heavy isotopes over Amazonia, despite reductions in rainfall, suggesting that the isotopic response is not a simple function of the "amount effect". During the South American monsoon season, the amplitude of the temperature response to volcanic forcing is larger than the rather weak and spatially less coherent precipitation signal, potentially masking the isotopic response to changes in the hydrologic cycle.

    The dawning of this millennium broke new ground in life science and technology, presented us genomic and proteomic revolution, nanotechnology innovation, and high performance liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS) used for separating and identifying new chemical entities at pico-, or even femto-concentrations. Applications of these high technologies to the traditional Chinese medicine (TCM) opened a new chapter in the ancient medicine, and prompted us to re-evaluate the thousand-year-old phytomedicine- ginseng from current perspectives. We, therefore, collected the latest information (mostly within 10 years) on ginseng, and condensed the information into two parts of this review serial. The present part covers etymology of ginseng, its pharmacognosy (natural origin, physical appearance, chemical properties, and specie identification), its cultivation and processing-related metabolic changes in active ingredients, standardized analytical methods used for quality control of various ginseng products, modern analytical methods used to identify and classify more than 100 chemical entities (many were recently unfolded) derived from ginseng species and their metabolites. The global markets and production of ginseng and relevant government regulations are herein updated to exchange information and understandings about current people's uses and cultivation of ginseng. The second part of the review serial will classify all these 100 chemical entities separated from various ginseng species into different groups based on their structural similarities, and summarize bioactivities of these entities. The second part of the review serial will also focus on recent findings of ginseng pharmacology and its clinical trials for various diseases, and brief side effects of ginseng. PMID:19601793

  4. Millennium development health metrics: where do Africa’s children and women of childbearing age live?

    PubMed Central

    2013-01-01

    The Millennium Development Goals (MDGs) have prompted an expansion in approaches to deriving health metrics to measure progress toward their achievement. Accurate measurements should take into account the high degrees of spatial heterogeneity in health risks across countries, and this has prompted the development of sophisticated cartographic techniques for mapping and modeling risks. Conversion of these risks to relevant population-based metrics requires equally detailed information on the spatial distribution and attributes of the denominator populations. However, spatial information on age and sex composition over large areas is lacking, prompting many influential studies that have rigorously accounted for health risk heterogeneities to overlook the substantial demographic variations that exist subnationally and merely apply national-level adjustments. Here we outline the development of high resolution age- and sex-structured spatial population datasets for Africa in 2000-2015 built from over a million measurements from more than 20,000 subnational units, increasing input data detail from previous studies by over 400-fold. We analyze the large spatial variations seen within countries and across the continent for key MDG indicator groups, focusing on children under 5 and women of childbearing age, and find that substantial differences in health and development indicators can result through using only national level statistics, compared to accounting for subnational variation. Progress toward meeting the MDGs will be measured through national-level indicators that mask substantial inequalities and heterogeneities across nations. Cartographic approaches are providing opportunities for quantitative assessments of these inequalities and the targeting of interventions, but demographic spatial datasets to support such efforts remain reliant on coarse and outdated input data for accurately locating risk groups. We have shown here that sufficient data exist to map the

  7. North Atlantic summer storm tracks over Europe dominated by internal variability over the past millennium

    2016-08-01

    Certain large, sustained anomalies in European temperatures in the past millennium are probably the result of internal variation. Such internal variations can modulate regional temperatures away from the expected response to greenhouse gas forcing. Here we assess the causes of European summer temperature variability over the past millennium using temperature observations, simulations and reconstructions. We find multidecadal-mean summer temperatures have varied within a span of 1 K, largely controlled by external forcing. By contrast, we find subcontinental variations, described by the temperature contrast between northern and southern Europe (the meridional temperature gradient), vary with a span of 2 K, and are controlled by internal processes. These variations are the result of redistributions of precipitation and cloud cover linked to oscillations in the position of the summer storm track. In contrast to recent twentieth-century winter-time trends, variations of the summer storm track over the past millennium show a weak response to external forcing, and instead are dominated by stochastic internal variability. We argue that the response of European summer temperatures to anthropogenic greenhouse forcing is likely to be spatially modulated by the same stochastic internal processes that have caused periods of cool, wet summers in northern Europe over the last millennium.

  6. Comparison of simulated and reconstructed variations in East African hydroclimate over the last millennium

    NASA Astrophysics Data System (ADS)

    Klein, François; Goosse, Hugues; Graham, Nicholas E.; Verschuren, Dirk

    2016-07-01

    The multi-decadal to centennial hydroclimate changes in East Africa over the last millennium are studied by comparing the results of forced transient simulations by six general circulation models (GCMs) with published hydroclimate reconstructions from four lakes: Challa and Naivasha in equatorial East Africa, and Masoko and Malawi in southeastern inter-tropical Africa. All GCMs simulate fairly well the unimodal seasonal cycle of precipitation in the Masoko-Malawi region, while the bimodal seasonal cycle characterizing the Challa-Naivasha region is generally less well captured by most models. Model results and lake-based hydroclimate reconstructions display very different temporal patterns over the last millennium. Additionally, there is no common signal among the model time series, at least until 1850. This suggests that simulated hydroclimate fluctuations are mostly driven by internal variability rather than by common external forcing. After 1850, half of the models simulate a relatively clear response to forcing, but this response is different between the models. Overall, the link between precipitation and tropical sea surface temperatures (SSTs) over the pre-industrial portion of the last millennium is stronger and more robust for the Challa-Naivasha region than for the Masoko-Malawi region. At the inter-annual timescale, last-millennium Challa-Naivasha precipitation is positively (negatively) correlated with western (eastern) Indian Ocean SST, while the influence of the Pacific Ocean appears weak and unclear. Although most often not significant, the same pattern of correlations between East African rainfall and the Indian Ocean SST is still visible when using the last-millennium time series smoothed to highlight centennial variability, but only in fixed-forcing simulations. This means that, at the centennial timescale, the effect of (natural) climate forcing can mask the imprint of internal climate variability in large-scale teleconnections.

    Background and Objectives: PA is a multi-factorial behavior that is affected by interpersonal, intra personal, environmental and social factors. In this study we applied explanatory model to determine the total, indirect and direct impact of physical environment, personal factors and social support on PA among employed women. Methods: This study was a correlational cross-sectional study which was conducted to model total, indirect and direct impact of environmental, psychological and social factors on PA. A total of 200 women were chosen from Tabriz University by using convenience sampling method. Data about demographic characteristics, psychological variables, social and physical environment were gathered by using self-reported questionnaire and also the PA was measured by using the International PA Questionnaire and pedometer. Results: personal factors, physical and social environment, showed direct effects on PA. Social factors could be seen to have indirect effects on PA through their influence on personal factors such as pros, cons and self-efficacy; also physical environment had indirect effects on PA through social environment. The total effects of physical and social environment on PA type were respectively 0.17, 0.16 on walking, 0.05, 0.07 on moderate activity and 0.15, 0.18 on vigorous activity. Conclusions: Findings from this study indicated that social factors had indirect effects on walking, moderate and vigorous activity, especially through the effects on these factors of self-efficacy, physical environment, pros and cons, and the interactive role of individual, environmental and social impacts on PA. The current study identifies that psychological, physical and social factors could be shown to have direct and indirect influences on all forms of activity. The barriers of PA were the most predictor of this behavior, and based on results, it can be concluded that decreasing the barriers along with improving social and physical environment can lead to

    The present investigation examines how personal self-regulation (presage variable) and regulatory teaching (process variable of teaching) relate to learning approaches, strategies for coping with stress, and self-regulated learning (process variables of learning) and, finally, how they relate to performance and satisfaction with the learning process (product variables). The objective was to clarify the associative and predictive relations between these variables, as contextualized in two different models that use the presage-process-product paradigm (the Biggs and DEDEPRO models). A total of 1101 university students participated in the study. The design was cross-sectional and retrospective with attributional (or selection) variables, using correlations and structural analysis. The results provide consistent and significant empirical evidence for the relationships hypothesized, incorporating variables that are part of and influence the teaching-learning process in Higher Education. Findings confirm the importance of interactive relationships within the teaching-learning process, where personal self-regulation is assumed to take place in connection with regulatory teaching. Variables that are involved in the relationships validated here reinforce the idea that both personal factors and teaching and learning factors should be taken into consideration when dealing with a formal teaching-learning context at university.

    The Narcissistic Personality Inventory (NPI) is currently the most widely used measure of narcissism in social/personality psychology. It is also relatively unique because it uses a forced-choice response format. We investigate the consequences of changing the NPI's response format for item meaning and factor structure. Participants were randomly assigned to one of three conditions: 40 forced-choice items (n = 2,754), 80 single-stimulus dichotomous items (i.e., separate true/false responses for each item; n = 2,275), or 80 single-stimulus rating scale items (i.e., 5-point Likert-type response scales for each item; n = 2,156). Analyses suggested that the "narcissistic" and "nonnarcissistic" response options from the Entitlement and Superiority subscales refer to independent personality dimensions rather than high and low levels of the same attribute. In addition, factor analyses revealed that although the Leadership dimension was evident across formats, dimensions with entitlement and superiority were not as robust. Implications for continued use of the NPI are discussed. PMID:25616401

  12. Financing the Millennium Development Goals for health and beyond: sustaining the 'Big Push'

    PubMed Central

    2010-01-01

    Many of the Millennium Development Goals are not being achieved in the world's poorest countries, yet only five years remain until the target date. The financing of these Goals is not merely insufficient; current evidence indicates that the temporary nature of the financing, as well as challenges to coordinating its delivery and directing it to the most needy recipients, hinder achievement of the Goals in countries that may benefit most. Traditional approaches to providing development assistance for health have not been able to address both prevalent and emergent public health challenges captured in the Goals; these challenges demand sustained forms of financial redistribution through a coordinated mechanism. A global social health protection fund is proposed to address recurring failures in the modern aid distribution mechanism. Such a Fund could use established and effective strategies for aid delivery to mitigate many financial problems currently undermining the Millennium Development Goals initiative. PMID:20932274

    Tuberculous meningitis (TBM) is a very common infectious disease in the central nervous system. The delay of diagnosing and treating TBM will lead to high disability and mortality of TBM. Hence, it is very important to promptly diagnose TBM early. In this work, we proposed a new method for diagnosing TBM with CSF samples by using UV-Vis absorption spectroscopy. CSF samples from TBM patients and non-TBM persons were compared, and the sensitivity, specificity, accuracy, positive predictive value reached 83.6%, 69.8%, 77.2%, 76.1% respectively. Our work indicated investigation of CSF using UV-Vis absorption spectroscopy might become a potentially useful method for TBM diagnosis.

    Treatment options are limited for families in which the child has severe and intractable disturbances of emotion and behavior, in which there is suspected or confirmed maltreatment by the mother, and in which the mother has her own history of childhood neglect and abuse. This paper proposes a model for understanding maltreatment in mother-child dyads, drawing upon the developmental psychopathology, behavior, and trauma literatures. At the core of this model is the hypothesis that a mother's maltreating behavior arises from unconscious attempts to experientially avoid the reemergence of an attachment-related dissociative part of the personality that contains the distress arising from her own early experiences of attachment relationships. The implications of this model for therapy are considered. PMID:21967177

    The structure and psychometric characteristics of the NEO-PI-3, a more readable version of the NEO-PI-R, are examined and compared with NEO-PI-R characteristics using data from college student observer ratings of 5,109 adolescents aged 12 to 17 from 24 cultures. Replacement items in the PI-3 showed on average stronger item/total correlations and slightly improved facet reliabilities compared with the NEO-PI-R in both English- and non-English-speaking samples. NEO-PI-3 replacement items did not substantially affect scale means compared with the original scales. Analyses across and within cultures confirmed the intended factor structure of both versions when used to describe young adolescents. We discuss implications of these cross-cultural findings for the advancement of studies in adolescence and personality development across the lifespan. PMID:19419953

    This study updates and provides evidence for the dimensionality, reliability, and validity of a standard instrument for detection and measurement of schizotypy in non-clinical young adults. Schizotypy represents a set of traits on which both nonclinical and schizophrenia-spectrum populations vary meaningfully. These traits are linked to biological, cognitive, and social dimensions of serious mental illness (SMI), to clinical and subclinical variation in personal and social functioning, and to risk for SMI. Reliable and valid identification of schizotypal traits has important implications for clinical practice and research. Four consecutive independent samples of undergraduates were administered the SPQ-BR (N=2552). Confirmatory factor analyses suggested a minor item wording change improved reliability, and this Updated questionnaire was implemented for three-quarters of the sample (SPQ-BRU). A, single-order, nine-factor structure had acceptable psychometric properties. The best fitting second-order structure included four higher-order factors that distinguished Social Anxiety and Interpersonal factors. This differentiation was supported by differential relationships with treatment history. The Disorganized factor had the greatest unique relationship with personal and family treatment history. With few exceptions, factor loadings showed stability across samples. Overall, the higher-order and lower-order factors of schizotypy demonstrated reliability and convergent and discriminant validity; detailed psychometric data are presented in a supplement.

    2001-06-01

    As today's business leaders are all too aware, a new scientific or technological break-through can quickly transform an industry's competitive landscape. The upheaval is often traumatic for the companies involved, forcing them to rethink their strategies and redefine their boundaries. But an industry in flux also creates vast opportunities. To seize them, companies must see how the current upheavals will affect the future distribution of profits--and then reinvent themselves to capitalize on the new sources of value. In this interview with HBR senior editor David Champion, Mark Levin, the founder and CEO of Millennium Pharmaceuticals, describes his vision of the future of the pharmaceutical industry in the wake of the genetics revolution and new technologies that have altered the economics of drug development. No company, he argues, will create serious long-term value by staying in just one or two stages of the value of chain. That's why Millennium, which started out doing basis research into genes and proteins and selling its findings to pharmaceutical giants, has moved downstream - toward the patients who actually use and pay for the drugs. He explains why the research end has become less lucrative than the more mechanical tasks of identifying, testing, and manufacturing molecules. Levin talks about the changes Millennium has undergone since its inception in 1993-from 30 workers to more than 1,000, and from one end of the value chain to the other. He discusses the company's cultural transformations as well as the partnerships and acquisitions that have helped millennium become involved in every stage of the chain-from gene to patient. Levin's vigorous approach to balancing long-term strategy with short-term tactics offers important lessons to any executive facing an industry upheaval. PMID:11408971

    Most studies about the higher-order dimensions to be considered in order to parsimoniously describe Personality Disorders (PDs) have identified between two and four factors but there is still no consensus about their exact number. In this context, the cultural stability of these structures might be a criterion to be considered. The aim of this study was to identify stable higher-order structures of PD traits in a French-speaking African and Swiss sample (N = 2,711). All subjects completed the IPDE screening questionnaire. Using Everett's criterion and conducting a series of principal component analyses, a cross-culturally stable two- and four-factor structure were identified, associated with a total congruence coefficient of .98 and .94, respectively, after Procrustes rotation. Moreover, these two structures were also highly replicable across the four African regions considered, North Africa, West Africa, Central Africa, and Mauritius, with a mean total congruence coefficient of .97 and .87, respectively. The four-factor structure presented the advantage of being similar to Livesely's four components and of describing the ten PDs more accurately. PMID:19379094

    The North Atlantic Oscillation (NAO) is the major source of variability in winter atmospheric circulation in the Northern Hemisphere, with large impacts on temperature, precipitation and storm tracks, and therefore also on strategic sectors such as insurance, renewable energy production, crop yields and water management. Recent developments in dynamical methods offer promise to improve seasonal NAO predictions, but assessing potential predictability on multi-annual timescales requires documentation of past low-frequency variability in the NAO. A recent bi-proxy NAO reconstruction spanning the past millennium suggested that long-lasting positive NAO conditions were established during medieval times, explaining the particularly warm conditions in Europe during this period; however, these conclusions are debated. Here, we present a yearly NAO reconstruction for the past millennium, based on an initial selection of 48 annually resolved proxy records distributed around the Atlantic Ocean and built through an ensemble of multivariate regressions. We validate the approach in six past-millennium climate simulations, and show that our reconstruction outperforms the bi-proxy index. The final reconstruction shows no persistent positive NAO during the medieval period, but suggests that positive phases were dominant during the thirteenth and fourteenth centuries. The reconstruction also reveals that a positive NAO emerges two years after strong volcanic eruptions, consistent with results obtained from models and satellite observations for the Mt Pinatubo eruption in the Philippines.

    Continuous HIV treatment is necessary to ensure successful combined antiretroviral therapy (cART). The aim of this study was to evaluate the incidence of patient-initiated non-structured treatment interruptions in HIV-infected persons who inject drugs and who received a multidisciplinary comprehensive program, including medical HIV care, drug-dependence treatment and psychosocial support, at a drug outpatient addiction center. Non-structured treatment interruptions were defined as ≥30 consecutive days off cART without medical indication. During a median follow-up of 53.8 months, 37/132 (28 %) patients experienced the first non-structured treatment interruptions. The cumulative probability of cART interruption at 5 years was 31.2 % (95 % CI 22.4-40.0). Current drug use injection ≥1/day (HR 14.77; 95 % CI 5.90-36.96) and cART naive patients (HR 0.35, 95 % CI 0.14-0.93) were predictive factors for non-structured treatment interruptions. HIV care provided at a drug addiction center is a useful strategy to sustain continuous cART, however, drug abstinence is essential for the long-term maintenance of cART. PMID:26427376

    Many pharmaceuticals and personal care products (PPCPs) have been shown to be biotransformed in water treatment systems. However, little research exists on the effect of initial PPCP concentration on PPCP biotransformation or on the microbial communities treating impacted water. In this study, biological PPCP removal at various concentrations was assessed using laboratory columns inoculated with wastewater treatment plant effluent. Pyrosequencing was used to examine microbial communities in the columns and in soil from a soil aquifer treatment (SAT; a method of water treatment prior to reuse) site. Laboratory columns were supplied with different concentrations (0.25, 10, 100, or 1,000 μg liter−1) of each of 15 PPCPs. Five PPCPs (4-isopropyl-3-methylphenol [biosol], p-chloro-m-xylenol, gemfibrozil, ketoprofen, and phenytoin) were not removed at any tested concentrations. Two PPCPs (naproxen and triclosan) exhibited removals independent of PPCP concentration. PPCP removal efficiencies were dependent on initial concentrations for biphenylol, p-chloro-m-cresol, chlorophene, diclofenac, 5-fluorouracil, ibuprofen, and valproic acid, showing that PPCP concentration can affect biotransformation. Biofilms from sand samples collected from the 0.25- and 10-μg liter−1 PPCP columns were pyrosequenced along with SAT soil samples collected on three consecutive days of a wetting and drying cycle to enable comparison of these two communities exposed to PPCPs. SAT communities were similar to column communities in taxonomy and phylotype composition, and both were found to contain close relatives of known PPCP degraders. The efficiency of biological removal of PPCPs was found to be dependent on the concentration at which the contamination occurs for some, but not all, PPCPs. PMID:24509919

Published by John Wiley & Sons Ltd., 2014 Ophthalmology has been an early adopter of personalized medicine. Drawing on genomic advances to improve molecular diagnosis, such as next-generation sequencing, and basic and translational research to develop novel therapies, application of genetic technologies in ophthalmology now heralds development of gene replacement therapies for some inherited monogenic eye diseases. It also promises to alter prediction, diagnosis and management of the complex disease age-related macular degeneration. Personalized ophthalmology is underpinned by an understanding of the molecular basis of eye disease. Two important areas of focus are required for adoption of personalized approaches: disease stratification and individualization. Disease stratification relies on phenotypic and genetic assessment leading to molecular diagnosis; individualization encompasses all aspects of patient management from optimized genetic counseling and conventional therapies to trials of novel DNA-based therapies. This review discusses the clinical implications of these twin strategies. Advantages and implications of genetic testing for patients with inherited eye diseases, choice of molecular diagnostic modality, drivers for adoption of personalized ophthalmology, service planning implications, ethical considerations and future challenges are considered. Indeed, whilst many difficulties remain, personalized ophthalmology truly has the potential to revolutionize the specialty. PMID:24665880

    2010-10-10

    We study the topology of cosmic large-scale structure through the genus statistics, using galaxy catalogs generated from the Millennium Simulation and observational data from the latest Sloan Digital Sky Survey Data Release (SDSS DR7). We introduce a new method for constructing galaxy density fields and for measuring the genus statistics of its isodensity surfaces. It is based on a Delaunay tessellation field estimation (DTFE) technique that allows the definition of a piece-wise continuous density field and the exact computation of the topology of its polygonal isodensity contours, without introducing any free numerical parameter. Besides this new approach, we also employ the traditional approaches of smoothing the galaxy distribution with a Gaussian of fixed width, or by adaptively smoothing with a kernel that encloses a constant number of neighboring galaxies. Our results show that the Delaunay-based method extracts the largest amount of topological information. Unlike the traditional approach for genus statistics, it is able to discriminate between the different theoretical galaxy catalogs analyzed here, both in real space and in redshift space, even though they are based on the same underlying simulation model. In particular, the DTFE approach detects with high confidence a discrepancy of one of the semi-analytic models studied here compared with the SDSS data, while the other models are found to be consistent.

    1999-06-01

    In Otorhinolaryngology the endoscopic appraisal of luminal dimensions of the nose, the throat, the larynx and the trachea is a daily problem. Those concerned with endoscopy know, that endoscopes distort dimensions of examined anatomical structures. To draw conclusions on luminal dimensions from the endoscopic pictures additional measuring devices are required. We developed a new method of measuring luminal dimensions in rigid or flexible endoscopy. For this a laser beam directed radially marks the anatomical lumen of interest in the videoendoscopic vision. The laser ring becomes deformed according to the form of the cavity explored. By keeping the distance defined between the laser ring and the top of the endoscope, the endoscopic video image can be measured. A piece of software developed by us calculates from the pictures the cross sectional area as well as the extension of benign or malign stenosis of the cavity explored. The result of the endoscopic measuring procedure can be visualized 3D on a PC-monitor. We are going to demonstrate the result of our clinical experience in different otorhinolaryngological diseases with the new endoscopic measuring kit in comparison to standard endoscopy. A further perspective is the endoscopic measuring kit in comparison to standard endoscopy. A further perspective is the endoscopic assisted manufacturing (EAM) of anatomical adapted stents, tubes and cannules.

    2009-01-01

    Changes in bioavailability of phosphorus (P) during pedogenesis and ecosystem development have been shown for geogenic calcium phosphate (Ca-P). However, very little is known about long-term changes of biogenic Ca-P in soil. Long-term transformation characteristics of biogenic Ca-P were examined using anthropogenic soils along a chronosequence from centennial to millennial time scales. Phosphorus fractionation of Anthrosols resulted in overall consistency with the Walker and Syers model of geogenic Ca-P transformation during pedogenesis. The biogenic Ca-P (e.g., animal and fish bones) disappeared to 3% of total P within the first ca. 2,000 years of soil development. This change concurred with increases in P adsorbed on metal-oxides surfaces, organic P, and occluded P at different pedogenic time. Phosphorus K-edge X-ray absorption near-edge structure (XANES) spectroscopy revealed that the crystalline and therefore thermodynamically most stable biogenic Ca-P was transformed into more soluble forms of Ca-P over time. While crystalline hydroxyapatite (34% of total P) dominated Ca-P species after about 600-1,000 years, {Beta}-tricalcium phosphate increased to 16% of total P after 900-1,100 years, after which both Ca-P species disappeared. Iron-associated P was observable concurrently with Ca-P disappearance. Soluble P and organic P determined by XANES maintained relatively constant (58-65%) across the time scale studied. Conclusions - Disappearance of crystalline biogenic Ca-P on a time scale of a few thousand years appears to be ten times faster than that of geogenic Ca-P.

  15. A multi-proxy model-tested NAO reconstruction for the last millennium

    In this study, we propose a new last millennium reconstruction of the winter North Atlantic Oscillation (NAO), the dominant mode of atmospheric variability in the North Atlantic. For this purpose, we use a selection of 60 annually to decadally resolved proxy records from different archives (ice cores, tree rings, speleothems, and lake and ocean sediments), which are distributed around the Atlantic Ocean and continental boundaries. These records are selected for showing a significant correlation with the longest instrumental NAO time series. The reconstruction is based on a Principal Component Regression (PCR) technique using a subset of the initial predictors. Two pseudo-proxy studies based on the Twentieth Century Reanalysis (20CR) and the last millennium PMIP3 simulations are performed to validate the choice of proxies and therefore produce a model and reanalysis-consistent NAO. This is a novel approach in which proxy and model worlds are combined with the aim of improving the reliability of the reconstruction. An ensemble of reconstructions is additionally generated to explore the potential uncertainties inherent to the reconstruction method (i.e. calibration period, number of PCs retained, level of significance imposed, and data smoothing). Thus, we provide a robust benchmark that enables us to test recent hypotheses. For example, no persistent positive NAO phase is observed during medieval times, in clear contrast with the bi-proxy NAO reconstruction by Trouet et al (2009). Furthermore, no significant link between the winter NAO and the external forcings is identified, thus opposed to previous results with climate models. Finally, our millennial reconstruction depicts a remarkable shift around 1450 AD, characterised by a fast negative-to-positive NAO transition lying within the range of recent winter NAO excursions. This result supports that 20th century NAO variability is not unprecedent in the context of the last millennium, in line with the IPCC AR5.

    This paper presents a reconstruction of climate-driven environmental changes over the last millennium in Hornsund Fjord (Svalbard), based on sedimentological and micropalaeontological records. Our palaeo-investigation was supported by an analysis of foraminiferal ancient DNA (aDNA), focusing on the non-fossilized monothalamous species. The main climatic fluctuations during the last millennium were the Medieval Warm Period (MWP, AD 1000-1600), the Little Ice Age (LIA, AD 1600-1900) and the modern warming (MW, AD 1900 to present). Our study indicates that the environmental conditions in Hornsund during the MWP and the early LIA (before ˜ AD 1800) were relatively stable. The beginning of the LIA (˜ AD 1600) was poorly evidenced by the micropalaeontological record but was well marked in the aDNA data by an increased proportion of monothalamous foraminifera, especially Bathysiphon sp. The early LIA (˜ 1600 to ˜ AD 1800) was marked by an increase in the abundance of sequences of Hippocrepinella hirudinea and Cedhagenia saltatus. In the late LIA (after ˜ AD 1800), the conditions in the fjord became glacier-proximal and were characterized by increased meltwater outflows, high sedimentation and a high calving rate. This coincided with an increase in the percentages of sequences of Micrometula sp. and Vellaria pellucidus. During the MW, the major glacier fronts retreated rapidly to the inner bays, which limited the iceberg discharge to the fjord's centre and caused a shift in the foraminiferal community that was reflected in both the fossil and aDNA records. The palaeoceanographic changes in the Hornsund fjord over the last millennium were driven mainly by the inflow of shelf-originated water masses and glacial activity. However, the environmental changes were poorly evidenced in the micropalaeontological record, but they were well documented in our aDNA data. We considerably increased the number of potential proxy species by including monothalamous foraminifera in the

    Large-scale climate history of the past millennium reconstructed solely from tree-ring data is prone to underestimate the amplitude of low-frequency variability. In this paper, we aimed at solving this problem by utilizing a novel method termed "MDVM", which was a combination of the ensemble empirical mode decomposition (EEMD) and variance matching techniques. We compiled a set of 211 tree-ring records from the extratropical Northern Hemisphere (30-90°N) in an effort to develop a new reconstruction of the annual mean temperature by the MDVM method. Among these dataset, a number of 126 records were screened out to reconstruct temperature variability longer than decadal scale for the period 850-2000 AD. The MDVM reconstruction depicted significant low-frequency variability in the past millennium with evident Medieval Warm Period (MWP) over the interval 950-1150 AD and pronounced Little Ice Age (LIA) cumulating in 1450-1850 AD. In the context of 1150-year reconstruction, the accelerating warming in 20th century was likely unprecedented, and the coldest decades appeared in the 1640s, 1600s and 1580s, whereas the warmest decades occurred in the 1990s, 1940s and 1930s. Additionally, the MDVM reconstruction covaried broadly with changes in natural radiative forcing, and especially showed distinct footprints of multiple volcanic eruptions in the last millennium. Comparisons of our results with previous reconstructions and model simulations showed the efficiency of the MDVM method on capturing low-frequency variability, particularly much colder signals of the LIA relative to the reference period. Our results demonstrated that the MDVM method has advantages in studying large-scale and low-frequency climate signals using pure tree-ring data. PMID:26751947

    This paper presents the reconstruction of climate-driven environmental changes of the last millennium from Hornsund Fjord (Svalbard) based on sedimentological and micropalaeontological records. Our palaeo-investigation was supported by the analysis of foraminiferal ancient DNA (aDNA), focusing on non-fossilised monothalamous species. The main climatic fluctuations over the last millennium were the Medieval Warm Period (MWP, 1000-1600 AD), the Little Ice Age (LIA, 1600-1900 AD), and the Modern Warming (MW, 1900 AD-present). Our study indicated that environmental conditions in Hornsund during the MWP and the early LIA (before ~ 1800 AD) were relatively stable, resulting from the distant position of glaciers. The beginning of the LIA (~ 1600 AD) was poorly evidenced by the micropalaeontological record, but well marked in the aDNA data, by an increased proportion of monothalamous foraminifera, especially Bathysiphon sp. The early LIA (~ 1600- ~ 1800 AD) was marked by the increase in abundance of sequences of Hippocrepinella hirudinea and Cedhagenia saltatus. In the late LIA (after ~ 1800 AD), conditions in the fjord became glacier-proximal, characterised by increased meltwater outflows, high sedimentation and a high calving rate. This coincided with an increase in the percentages of sequences of Micrometula sp. and Vellaria pellucidus.

    The European summer heatwaves have been increasing in frequency and magnitude in the past decades. A higher confidence in future changes in such extremes necessitates to have a better knowledge about extremes behavior in the past climate. The last millennium is well documented in terms of climate forcings. Modelling efforts have provided a wealth of climate simulations covering the last millennium. We want to exploit such data in order to assess how models simulate extreme summer heatwaves. The surface temperature and precipitation are closely related to atmospheric patterns. It has been shown that rainy winter/spring seasons reduce the frequency of hot summer days whereas dry seasons can be followed by summers with high or low frequency of hot days. In this poster, we show the relation between winter/spring precipitation with the frequency of hot days in the 10 hottest summers in Europe and Southern Europe during the Medieval Warm Period (MWP 1150-1250), the Little Ice Age (LIA 1650-1750), and the historical-present period (1850-2005). We first focus on a millennium simulations with the IPSL model (IPSL-CM5). We use daily temperature, precipitation, and SLP data from CMIP5 (Coupled Model Intercomparison Project phase 5) and a couple of IPSL simulations with diferents forcings. Summer weather regimes has been computed as well for NCEP sea level pressure data in order to compare observations with the same period (1948-2005) in CMIP5 and IPSL simulations outputs. We discuss and present the results comparing the effects of hydrological deficits in the preceding season, and the occurrence of specific weather regimes, during the hottest summers over Europe and SouthWestern Europe. This analysis compares differents climate forcings simulations.

    Determining past changes in the amplitude, frequency and teleconnections of the El Niño-Southern Oscillation (ENSO) is important for understanding its potential sensitivity to future anthropogenic climate change. Palaeo-reconstructions from proxy records can provide long-term information of ENSO interactions with the background climatic state through time. However, it remains unclear how ENSO characteristics have changed on long timescales, and precisely which signals proxies record. Proxy interpretations are typically underpinned by the assumption of stationarity in relationships between local and remote climates, and often utilise archives from single locations located in the Pacific Ocean to reconstruct ENSO histories. Here, we investigate the long-term characteristics of ENSO and its teleconnections using the Last Millennium experiment of CMIP5 (Coupled Model Intercomparison Project phase 5; Taylor et al., 2012). We show that the relationship between ENSO conditions (NINO3.4) and local climates across the Pacific basin differs significantly for 100-year epochs defining the Last Millennium and the historical period 1906-2005. Furthermore, models demonstrate decadal- to centennial-scale modulation of ENSO behaviour during the Last Millennium. Overall, results suggest that the stability of teleconnections may be regionally dependent and that proxy climate records may reveal complex changes in teleconnected patterns, rather than large-scale changes in base ENSO characteristics. As such, proxy insights into ENSO may require evidence to be considered over large spatial areas in order to deconvolve changes occurring in the NINO3.4 region from those relating to local climatic variables. To obtain robust histories of the ENSO and its remote impacts, we recommend interpretations of proxy records should be considered in conjunction with palaeo-reconstructions from within the central Pacific.

    The millennium promises a dramatic politicisation of the food question. In addition to the prominent issues of food security, hunger and nutrition, bioengineering, food safety and quality, there are related issues of environmental sustainability, power, sovereignty and rights. All these issues are deeply implicated in the current corporate form of globalisation, which is transforming historic global arrangements by subordinating public institutions and the question of food security to private solutions. The present paper questions the self-evident association between globalisation and nutritional improvement. PMID:11681637

    Simulations of climate over the Last Millennium (850-1850 CE) have been incorporated into the third phase of the Paleoclimate Modelling Intercomparison Project (PMIP3). The drivers of climate over this period are chiefly orbital, solar, volcanic, changes in land use/land cover and some variation in greenhouse gas levels. While some of these effects can be easily defined, the reconstructions of solar, volcanic and land use-related forcing are more uncertain. We describe here the approach taken in defining the scenarios used in PMIP3, document the forcing reconstructions and discuss likely implications.

    In a developing country such as Pakistan, where illiteracy, poverty, gender differences, and health issues are prevalent, violence against women is a commonly observed phenomenon. The rising incidences of abuse among women indicate a need to introduce evidence-based community-derived interventions for meeting Millennium Developmental Goals by 2015. This article discusses the application of counseling, economic skills building, and microcredit programs as practical and effective interventions to improve the health outcomes of abused women and, therefore, improving maternal and child health in the Pakistani society.

    Objective: The categorical-dimensional status of DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) conduct disorder (CD) and antisocial personality disorder (ASPD) is a source of controversy. This study examined whether the underlying structure of DSM-IV CD and ASPD was dimensional or categorical (taxonic) among individuals with and without substance use disorders. Method: Using a national large representative survey of U.S. adults (n = 43,093), taxometric analyses of DSM-IV CD and ASPD diagnostic criteria were conducted on the total sample and among those with and without substance use disorders. Results: Results of three taxometric procedures were consistent in showing that the structures underlying DSM-IV CD and ASPD were clearly taxonic in the total sample and among individuals with and without substance use disorders. Comparison curve fit indices exceeded 0.57 for each model. Conclusions: Taxonic findings of the present study were in contrast to the dimensional results of prior taxometric research among incarcerated samples with substantial comorbidity of antisocial syndromes and substance use disorders. Results supported the categorical representation and diagnostic thresholds of ASPD and CD as defined in DSM-IV and DSM-5. That the structure of ASPD and CD may be taxonic suggests that further research on these disorders use group comparative designs in which samples with and without these disorders are compared in terms of sociodemographic and clinical correlates, comorbidity, and treatment utilization. The taxonic structure of ASPD and CD may contribute to future research on causal processes through which these antisocial syndromes develop. PMID:24766762

    How do we acquire a mental representation of our own face? Recently, synchronous, but not asynchronous, interpersonal multisensory stimulation (IMS) between one’s own and another person’s face was used to evoke changes in self-identification (enfacement illusion). We investigated the conscious experience of these changes with principal component analyses (PCA) that revealed that while the conscious experience during synchronous IMS focused on resemblance and similarity with the other’s face, during asynchronous IMS it focused on multisensory stimulation. Analyses on the identified common factor structure revealed significant quantitative differences between synchronous and asynchronous IMS on self-identification and perceived similarity with the other’s face. Experiment 2 revealed that participants with lower interoceptive sensitivity experienced stronger enfacement illusion. Overall, self-identification and body-ownership rely on similar basic mechanisms of multisensory integration, but the effects of multisensory input on their experience are qualitatively different, possibly underlying the face’s unique role as a marker of selfhood.

As on other occasions, this was reflected in the excellent collaboration between the National Radiologists' Union (SNR), the Italian Association of Medical Physics (AIFM) and the National Federation of Radiology Technicians (F.N.C.TSRM) in drafting the document. The document aims to highlight the potentialities and limitations in the use of Teleradiology and to provide a set of recommendations/guidelines, which are not, however, to be intended as strict, absolute rules. Because this field is continually evolving both in structural and regulatory terms, and because it is very difficult to establish universal criteria to rigidly define behavioural models for implementing and managing Teleradiology-related activities (which in any case fall into the category of radiological medical acts), the recommendations/guidelines proposed necessarily have an informative rather than prescriptive nature. The document starts by defining the meaning of the following currently used terms: Teleconsultation; Telediagnosis; Teledidactics. It then goes on to analyse the following aspects of Teleradiology: Technological requirements; Qualifications and training of Medical Personnel; Qualifications, training and competences of Radiology Technicians. Based on the regulations in force in Italy, these recommendations are structured in terms of rationale and possible professional issues arising from the use of Teleradiology. A section is devoted to data security and confidentiality, including legal implications, an area which is currently evolving and being studied in Italy and abroad. Finally, the professional liabilities of all the healthcare providers involved in Teleradiology (imprudence, incompetence, negligence) are outlined, as well as the responsibilities related to the necessary maintenance of equipment. The aim of the document is to propose recommendations/guidelines for the correct use and

    This study aimed to establish correlates of the dimensions of schizophrenia in the premorbid personality traits of patients. A sample of 112 patients of relatively recent illness onset who were admitted for a psychotic episode were assessed with a semistructured interview for schizophrenia. Positive and negative symptoms were evaluated with the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms at the time of hospital discharge; positive, negative, and disorganization scores were obtained from these scales. Premorbid personality was assessed blindly through a partially modified version of the Personality Assessment Schedule using interviews with the parents or a close relative. Schizoid traits were significantly associated with negative and positive dimensions. Sociopathic traits were related to the disorganization dimension. Trends toward significance were obtained between passive-dependent traits and the negative and disorganization dimensions, and between the schizotypal dimension and the positive dimension. Partial correlational analyses were used to control for the effect of the remaining personality dimensions on the above relationships. Schizoid premorbid traits were still significantly related to the negative dimension but to a lesser degree to the disorganization and positive dimensions. The association between sociopathic premorbid traits and the disorganization dimension remained significant. These results suggest the preexistence of a three-dimensional structure predisposing to psychoses within the premorbid personality; this structure is more evident in patients with short illness duration.

    The centennial-millennial variation of the East Asian summer monsoon (EASM) precipitation over the past 1000 years was investigated through the analysis of a millennium simulation of the coupled ECHO-G model. The model results indicate that the centennial-millennial variation of the EASM is essentially a forced response to the external radiative forcing (insolation, volcanic aerosol, and green house gases). The strength of the response depends on latitude; and the spatial structure of the centennial-millennial variation differs from the interannual variability that arises primarily from the internal feedback processes within the climate system. On millennial time scale, the extratropical and subtropical precipitation was generally strong during Medieval Warm Period (MWP) and weak during Little Ice Age (LIA). The tropical rainfall is insensitive to the effective solar radiation forcing (insolation plus radiative effect of volcanic aerosols) but significantly responds to the modern anthropogenic radiative forcing. On centennial time scale, the variation of the extratropical and subtropical rainfall also tends to follow the effective solar radiation forcing closely. The forced response features in-phase rainfall variability between the extratropics and subtropics, which is in contrast to the anti-correlation on the interannual time scale. Further, the behavior of the interannual-decadal variation in the extratropics is effectively modulated by change of the mean states on the millennial time scale, suggesting that the structure of the internal mode may vary with significant changes in the external forcing. These findings imply that on the millennial time scale, (a) the proxy data in the extratropical EA may more sensitively reflect the EASM rainfall variations, and (b) the Meiyu and the northern China rainfall provide a consistent measure for the EASM strength.

    In this paper we assess South American Monsoon System (SAMS) variability throughout the Last Millennium as depicted by the Coupled Modelling Intercomparison Project version 5/Paleo Modelling Intercomparison Project version 3 (CMIP5/PMIP3) simulations. High-resolution proxy records for the South American monsoon over this period show a coherent regional picture of a weak monsoon during the Medieval Climate Anomaly period and a stronger monsoon during the Little Ice Age (LIA). Due to the small forcing during the past 1000 years, CMIP5/PMIP3 model simulations do not show very strong temperature anomalies over these two specific periods, which in turn do not translate into clear precipitation anomalies, as suggested by rainfall reconstructions in South America. However, with an ad-hoc definition of these two periods for each model simulation, several coherent large-scale atmospheric circulation anomalies were identified. The models feature a stronger Monsoon during the LIA associated with: (i) an enhancement of the rising motion in the SAMS domain in austral summer, (ii) a stronger monsoon-related upper-troposphere anticyclone, (iii) activation of the South American dipole, which results to a certain extent in a poleward shift in the South Atlantic Convergence Zone and (iv) a weaker upper-level sub tropical jet over South America, this providing important insights into the mechanisms of these climate anomalies over South America during the past millennium.

    Background Achieving sustainable economic and social growth through advances in health is crucial in Latin America within the framework of the United Nations Millennium Development Goals. Discussion Health-related Millennium Development Goals need to incorporate a multidimensional approach addressing the specific epidemiologic profile for each region of the globe. In this regard, addressing the cycle of destitution and suffering associated with infection with Trypanosoma cruzi, the causal agent of Chagas disease of American trypanosomiasis, will play a key role to enable the most impoverished populations in Latin America the opportunity to achieve their full potential. Most cases of Chagas disease occur among forgotten populations because these diseases persist exclusively in the poorest and the most marginalized communities in Latin America. Summary Addressing the cycle of destitution and suffering associated with T. cruzi infection will contribute to improve the health of the most impoverished populations in Latin America and will ultimately grant them with the opportunity to achieve their full economic potential.

    The South Asian summer monsoon (SASM) is a major atmospheric synoptic climate system affecting nearly a quarter of the human population. Climate proxy data derived from tree rings, ice cores, speleothems, and other sources can all contribute to an understanding of SASM variability prior to instrumental period. Here, we develop an optimal information extraction (OIE) method, which we use to reconstruct the SASM index (SASMI) over the last millennium using 15 tree-ring chronologies. The record generated is significantly correlated (r = 0.7, p < 0.01) with the instrumental SASMI record on annual timescales; this correlation is higher than that obtained in any previous study. The reconstructed SASMI captures 18 of 26 (69%) reordered historical famine events in India over the last millennium; notably, 11 of 16 short events with durations of 1–3 years are accurately depicted in our reconstruction. Moreover, the reconstructed SASMI is positively correlated with variations in total solar irradiance (TSI) on multi-decadal timescales implying that variations in solar activity may influence the SASM. Based on the response of SASM to 34 significant volcanic events using the superposed epoch analysis, the volcanic forcing may drive a weak SASM in the second year of an eruption. PMID:25338702

    Knowledge of natural long-term drought variability is essential for water resource management and planning, especially in arid and sub-arid regions of the world. In the eastern Qilian Mountains of China, long-term drought variability based on high-resolution proxy records such as tree-ring data are still scarce to date. Here we present a new tree-ring chronology from the eastern Qilian Mountains which provides a valuable 1,002-year record (1009-2010 CE) of drought variability. The new reconstruction of June-July 5-month scale standardized precipitation and evapotranspiration index is the first millennium tree-ring estimate of past climate developed in the eastern Qilian Mountains. The record shows that this region has experienced several persistent droughts and pluvials over the past millennium, with significantly drier climate during the fifteenth century and dramatic wetting since the nineteenth century. The low frequency generally agrees with other nearby studies based on both tree-ring data and other proxy data.

    The Pacific ocean-atmosphere system exerts an important influence on the climate of Asia and North America, but the limited length of the observational record prevents a complete understanding of its bidecadal and multidecadal time scales. Paleoclimate reconstructions provide one source of information on longer time scales, although they differ in their estimation of the behavior of the Pacific decadal oscillation (PDO) prior to the instrumental period. Forced general circulation model simulations offer complementary long-term perspectives on both the history and dynamics of this important mode of variability. Here, we analyze the PDO in the ensemble of CMIP5/PMIP3 last millennium (past1000 + historical) simulations. We evaluate the modeled spatial, temporal, and spectral characteristics of this mode, as well as teleconnections between North Pacific variability and global climate. All models produce a mode of North Pacific variability over the last millennium with spatial patterns and spectral power density similar to observations. CCSM, FGOALS, and IPSL best reproduce observed spatial patterns, spectral characteristics, and teleconnections to terrestrial regions used in paleoclimate proxy reconstructions. In these simulations, the PDO shows no consistent response to solar or volcanic forcing.

    This study investigates the millennium water vapour drop, the abrupt and severe water vapour decline in the stratosphere beginning in year 2000, by means of various simulations using the Chemistry-Climate Model (CCM) EMAC. Since the beginning 1980s, balloon borne stratospheric water vapour measurements and corresponding satellite measurements starting in the early 1990s indicated a long-term steady increase of water vapour concentrations. However, the multi-year data sets also show significant fluctuations on different time scales. In the year 2000, an extraordinary sudden drop of stratospheric water vapour concentration has been observed followed by persistent low values for several years. Solomon et al. (2010) showed that this drop slowed down the rate of increase in global surface temperature over the following decade by about 25%. So far, the stratospheric water vapour variations observed by satellite from 1992 to 2012 are not reproduced by CCM simulations forced by observed changes in sea surface temperatures, greenhouse gases and ozone-depleting substances (Gettelman et al., 2010, Randel and Jensen, 2013). However, the CCM EMAC is able to reproduce the signature and pattern of the water vapour disturbances in agreement with those derived from observations. In this paper we present results of a hierarchy of simulations with the CCM EMAC, demonstrating that it is possible to retrace the observed water vapour fluctuations in the stratosphere (incl. the millennium drop), if suitable inner and outer boundary conditions are applied.

    The South Asian summer monsoon (SASM) is a major atmospheric synoptic climate system affecting nearly a quarter of the human population. Climate proxy data derived from tree rings, ice cores, speleothems, and other sources can all contribute to an understanding of SASM variability prior to instrumental period. Here, we develop an optimal information extraction (OIE) method, which we use to reconstruct the SASM index (SASMI) over the last millennium using 15 tree-ring chronologies. The record generated is significantly correlated (r = 0.7, p < 0.01) with the instrumental SASMI record on annual timescales; this correlation is higher than that obtained in any previous study. The reconstructed SASMI captures 18 of 26 (69%) reordered historical famine events in India over the last millennium; notably, 11 of 16 short events with durations of 1-3 years are accurately depicted in our reconstruction. Moreover, the reconstructed SASMI is positively correlated with variations in total solar irradiance (TSI) on multi-decadal timescales implying that variations in solar activity may influence the SASM. Based on the response of SASM to 34 significant volcanic events using the superposed epoch analysis, the volcanic forcing may drive a weak SASM in the second year of an eruption. PMID:25338702

  2. Emerging diseases and implications for Millennium Development Goals in Africa by 2015 - an overview.

    Emerging zoonotic diseases have assumed increasing fundamental importance in both public and animal health, as the last few years have seen a steady increase of new cases, each emerging from an unsuspected geographic area and causing serious problems, often leading to mortalities among animals and humans. The reasons for disease emergence or re-emergence are multiple and include certain major factors, such as expansion of the human population, climate change and globalisation of trade. Further contributing issues, such as the increased movement of animal species, microbial evolution, ecological disruption, changes in human behaviour, all imply that emerging diseases will not only continue to occur, but the rate of their emergence will also increase. These will constitute constraints for the attainment of the Millennium Development Goals by African Governments by 2015. There is no doubt that the current trend calls for more and stronger partnerships between national and international organisations, veterinary and medical communities, environmentalists, academics and policy-makers of various governments on the continent within the context of the global 'One Health' movement. This article attempts to analyse the impact of emerging diseases and the implications for the achievement of the Millennium Development Goals in Africa by the year 2015. PMID:20560123

    Solar irradiance changes are thought to play an important role in natural climate variability. How solar activities affected hydrological changes in westerly-controlled arid central Asia (ACA) on decadal/centennial timescales remains poorly investigated, due to lack of high-quality records. Here we present high-resolution multi-proxy records of lake level changes, and thus effective moisture fluctuations, over the last millennium, from a shoreline sediment core retrieved from Lake Manas, northwestern China. Besides generally confirmed relatively wet conditions during the cool Little Ice Age, records of the geophysical and geochemical indicators, including lightness, calcium counts, and C37 alkenone contents, consistently show substantial and frequent lake level fluctuations, and more importantly, resemble solar irradiance changes. Further, the ~11-year Schwabe cycle, ~70-100-year Gleissberg cycle, and relatively weak spectral power in between, as characters in the sunspot number record, together with the ~200-year Suess-de Vries cycle revealed in the reconstructed total solar irradiance records, are all evident in the higher-resolution calcium and lightness records. Together, our records clearly demonstrate solar imprints on effective moisture fluctuations in ACA over the last millennium, and the occurrence of the Schwabe cycle even during the solar minima.

    Goddard Institute for Space Studies (GISS)-E2-R sampled the broadest range of boundary conditions for simulations of the last millennium, with a dozen different experiments sampling three different volcanic forcing scenarios, three anthropogenic land use change scenarios, and three different solar (TSI) scenarios. This suite of experiment yields 15,000 years of simulations for the last millennium. Here the forcings of these experiments are distilled down into basic fingerprints of each type of change - volcanic, solar, and, anthropogenic land use - to test whether it is feasible to detect these climate changes in various proxy archives. I will illustrate the difficulty in the detection of any of these changes in individual proxy archives, and establish the minimum critieria (given a perfect simulation) to identify solar minima, volcanic eruptions, and large changes in land use. Further, preliminary new results to illustrate the impact of various degrees of sophistication in applying volcanic forcing on the resultant climate signal will be presented. We will also study the impact of atmospheric composition on climate, by presenting results from atmosphere-only model simulations with the GISS-E2 model, which includes interactive gas-phase chemistry and aerosols at decadal-scale time slices, driven by the millennial-length coupled atmosphere-ocean simulations.

    The NASA Lewis Research Center continues to demonstrate its expertise in the development and implementation of advanced space power systems. For example, during the past year, the NASA New Millennium Program selected the Solar Concentrator Array with Refractive Linear Element Technology (SCARLET) photovoltaic array as the power system for its Deep Space-1 (DS-1) mission. This Jet Propulsion Laboratory (JPL) managed DS-1 mission, which represents the first operational flight of a photovoltaic concentrator array, will provide a baseline for the use of this technology in a variety of future government and commercial applications. SCARLET is a joint NASA Lewis/Ballistic Missile Defense Organization program to develop advanced photovoltaic array technology that uses a unique refractive concentrator design to focus sunlight onto a line of photovoltaic cells located below the optical element. The general concept is based on previous work conducted at Lewis under a Small Business Innovation Research (SBIR) contract with AEC-Able Engineering, Inc., for the Multiple Experiments to Earth Orbit and Return (METEOR) spacecraft. The SCARLET II design selected by the New Millennium Program is a direct adaptation of the smaller SCARLET I array built for METEOR. Even though SCARLET I was lost during a launch failure in October 1995, the hardware (designed, built, and flight qualified within 6 months) provided invaluable information and experience that led to the selection of this technology as the primary power source for DS-1.

    Biomedical interventions promise achievement of health-related Millennium Development Goals provided social-, capacity- and knowledge-based constraints to scaling up and reaching marginalized people at risk, are addressed, and balance between prevention and treatment is struck. We argue for a new approach: multi-stakeholder capacity building and learning for empowerment: MuSCLE. MuSCLE is used as a way to frame three systemic weaknesses in traditional health science and policy approaches: 1) a lack of engagement with people at risk to build a collective understanding of the contexts of health problems; 2) a lack of multi-criteria evaluation of alternative interventions; and 3) a lack of attention paid to integrated capacity building. The MuSCLE framework responds in three ways: 1) Participatory assessment of the ecological, socio-cultural, economic and political contexts of health, identifying priorities using risk and vulnerability science, and modeling drivers; 2) Selection among intervention alternatives that makes ecological, socio-cultural, economic and political tradeoffs transparent; and 3) Integrated capacity building for sustainable and adaptive interventions. Literature and field lessons support the argument, and guidelines are set down. A MuSCLE approach argues for a transformation in health science and policy in order to achieve Millennium Development Goals for health. PMID:17399849

    Numerous health legislations concerning child mortality, maternal health and life-threatening diseases such as polio and tuberculosis are crafted in the health sector of Pakistan. A critical assessment of health legislations points to their in-effective or sub-optimal implementation. By engaging with the concept of public law, there is a strong relationship of public health and health legislations. While the basic purpose of health legislations is to craft and enforce essential health legislations for improving public health, an examination of health legislations across Pakistan indicate an extensive health engagement which is facing certain challenges indicating traditional health practices, enforcement constraints arising due to political compulsions and complexities, and systematic problems in the health sector, reflecting issue of governance. Through focus group discussions and in-depth interviews held with policy-makers, senior health officials private health entities and parliamentarian tasks forces on millennium development goals, this study engages with health-sector legislations. In so doing, it focuses on the problematic health sector and interventions. It is observed that unless an overarching legislative framework and a shift from programmatic approach to a human rights approach is adopted, the targets of millennium development goals 4, 5 and 6 would remain off-track in Pakistan.

    To investigate ocean variability during the last millennium in the Western Gulf of Maine (GOM), we collected a 142-year-old living bivalve ( Arctica islandica L.) in 2004, and three fossil A. islandica shells (calibrated 14CAMS = 1030 ± 78 ad; 1320 ± 45 ad; 1357 ± 40 ad) for stable isotope and growth increment analysis. A statistically significant relationship exists between modern GOM temperature records [shell isotope-derived (30 m) ( r = -0.79; P < 0.007), Prince 5 (50 m) ( r = -0.72; P < 0.019), Boothbay Harbor SST ( r = -0.76; P < 0.011)], and Labrador Current (LC) transport data from the Eastern Newfoundland Slope during 1993-2003. In all cases, as LC transport increased, GOM water temperatures decreased the following year. Decadal trends in the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO) influence GOM water temperatures in the most recent period, with water temperatures decreasing during NAO and AMO negative modes most likely linked to LC transport and Gulf Stream interaction. Mean shell-derived isotopic changes (δ18Oc) during the last 1,000 years were +0.47‰ and likely reflect a 1-2°C cooling from 1000 ad to present. Based on these results, we suggest that observed cooling in the GOM during the last millennium was due to increased transport and/or cooling of the LC, and decreased Gulf Stream influence on the GOM.

    2000-01-01

    The MicroPLB (personal locator beacon) is a search and rescue satellite-aided tracking (SARSAT) transmitter. When activated it emits a distress signal to a constellation of internationally operated satellites. The endangered person's identity and location anywhere on Earth is automatically forwarded to central monitoring stations around the world. It is accurate to within just a few meters. The user uses the device to download navigation data from a global positioning satellite receiver. After the download is complete, the MicroPLB functions as a self-locating beacon. Also, it is the only PLB to use a safe battery. In the past, other PLB devices have used batteries that have enough volatility to explode with extreme force. It was developed by Microwave Monolithic, Inc. through SBIR funding from Glenn Research Center and Goddard Space Flight Center.

    Background. Investigations in the field of gender identity disorder (GID) have been mostly related to psychiatric comorbidity and severe psychiatric disorders, but have focused less on personality and personality disorders (PDs). Aims. The aim of the study was to assess the presence of PDs in persons with GID as compared to cisgendered (a cisgender person is a person who is content to remain the gender they were assigned at birth) heterosexuals, as well as to biological sex. Methods. The study sample consisted of 30 persons with GID and 30 cisgendered heterosexuals from the general population. The assessment of PDs was conducted by application of the self-administered Structured Clinical Interview for DSM-IV Axis II PDs (SCID-II). Results. Persons with GID compared to cisgender heterosexuals have higher presence of PDs, particularly Paranoid PD, avoidant PDs, and comorbid PDs. In addition, MtF (transwomen are people assigned male at birth who identify as women) persons are characterized by a more severe psychopathological profile. Conclusions. Assessment of PDs in persons with GID is of great importance as it comprises a key part of personalized treatment plan tailoring, as well as a prognostic factor for sex-reassignment surgery (SRS) outcome.

  13. Sensitivity of Asian climate change to radiative forcing during the last millennium in a multi-model analysis

    2016-04-01

    The outputs of last millennium (A.D. 850-1850) experiments from seven climate models of the Paleoclimate Modeling Intercomparison Project 3, have been used to analyze decadal to centennial climatic variations over Asia, including the Indian monsoon, the East Asian monsoon and the westerly jet. In particular, the differences between the Medieval Warm Period (MWP, A.D. 901-1200) and the Little Ice Age (LIA, A.D. 1551-1850) are focused on. Statistically, significant temperature contrasts between the MWP and LIA are simulated by all of the models, and larger temperature deviations occur during colder periods. Although discrepancies exist, stronger Indian and East Asian summer monsoon circulations, as well as a stronger Asian westerly jet stream in winter, are found during the MWP compared to the LIA, in most of the models. These changes primarily originate from different atmospheric thermal structures over the two periods, which occur in response to the external radiative forcings. However, the monsoon-associated precipitation is quite complicated, with distinctly different patterns simulated among the models. There are phase differences in the multi-decadal variability of precipitation among the models, which consistently fail to detect a weakening in the precipitation at the minima of the radiative forcings. Only limited models are able to simulate the quasi-100-year solar cycles in the changes of precipitation over India and East Asia. Thus, although the climate system is certainly affected by external radiative forcings, our results imply that the natural forcings may not exert such a substantial influence on the Asian monsoon rainfall, or the models may underestimate the response.

    2015-04-01

    Changes in the climate mean state are expected to influence society, but the socio-economic sensitivity to extreme events might be even more severe. Whether or not the current frequency and severity of extreme events is a unique characteristic of anthropogenic-driven climate change can be assessed by putting the observed changes in a long-term perspective. In doing so, early instrumental series and proxy archives are a rich source to investigate also extreme events, in particular during the last millennium, yet they suffer from spatial and temporal scarcity. Therefore, simulations with coupled general circulation models (GCMs) could fill such gaps and help in deepening our process understanding. In this study, an overview of past and current efforts as well as challenges in modelling paleo weather and extreme events is presented. Using simulations of the last millennium we investigate extreme midlatitude cyclone characteristics, precipitation, and their connection to large-scale atmospheric patterns in the North Atlantic European region. In cold climate states such as the Maunder Minimum, the North Atlantic Oscillation (NAO) is found to be predominantly in its negative phase. In this sense, simulations of different models agree with proxy findings for this period. However, some proxy data available for this period suggests an increase in storminess during this period, which could be interpreted as a positive phase of the NAO - a superficial contradiction. The simulated cyclones are partly reduced over Europe, which is consistent with the aforementioned negative phase of the NAO. However, as the meridional temperature gradient is increased during this period - which constitutes a source of low-level baroclincity - they also intensify. This example illustrates how model simulations could be used to improve our proxy interpretation and to gain additional process understanding. Nevertheless, there are also limitations associated with climate modeling efforts to

  9. High-Resolution Reconstructions of Temperature and Precipitation During the Last Millennium from Lake Tanganyika, Africa

    Mayes, M.; Tierney, J.; Huang, Y.; Russell, J.

    2008-12-01

    Though numerous syntheses of high-resolution paleoclimate data have documented temperature changes associated with the Medieval Period, the Little Ice Age, and the Industrial era in north temperate regions, few records of temperature variability exist for the Southern Hemisphere (Mann and Jones, 2003, GRL doi: 10.1029/2003GL017814). Here, we present a new, high-resolution record of terrestrial temperature and rainfall from southeast tropical Africa, based upon organic geochemical analyses of annually laminated sediment cores from Lake Tanganyika, East Africa, providing the first millennium-long, high-resolution record of temperature from the East African tropics. Extending to 700CE with decadal resolution, the record uses the TEX86 paleothermometer and hydrogen stable isotope ratios (dD) of leaf waxes, which have been shown to reflect temperature and hydrologic conditions in Tanganyika, respectively (Tierney 2008, Science). The TEX86-based temperature reconstruction shows that Tanganyika temperatures were relatively warm at 700CE, cooler from 800-1000CE, and then warmer again between approximately 1050-1300CE. The latter warm interval is coincident with periods of warmer temperatures documented in the Northern Hemisphere. Yet temperatures are highly variable within the Little Ice Age (~1450-1800CE) and do not cool substantially relative to older time periods, in contrast to north temperate regions. Pronounced warming from approximately 1850 to the present is unprecedented in comparison to patterns of temperature variability during the previous centuries. The temperature variability documented here does not seem to correspond strongly to lake level fluctuations in Tanganyika over the past millennium (Cohen et al., 2005, JoPL, doi 10.1007/s10933-005- 2422-4), suggesting that Southeast African climate variability is more complex than alternating cycles of warm/wet and cool/dry conditions. dD analyses document considerable hydrologic variability over the past

    2006-12-01

    The reconstructed temperature anomalies in the eastern China were compared with the output from a 1000- year model simulation in an attempt to evaluate the model's regional simulation skills and to understand the causes of climate change in China over the last millennium. The reconstructed data are the winter half-year temperature anomalies in the central region of eastern China (25°-40'N, east of 105°E) for the last 1000 years with a 30-year resolution. The model used is the global atmosphere-ocean coupled climate model, ECHO-G, which was driven by time-varying external forcings including solar radiation, volcanic eruptions, and greenhouse gas concentrations (CO2 and CH4) for the same period. The correlation coefficient between the simulated and reconstructed time series is 0.37, which is statistically significant at a confidence level of 97.5%. The Medieval Warm Period (MWP) during 1000£­1300 A.D., the Little Ice Age (LIA) during 1300£­1850 A.D. and the modern warming period after 1900 A.D. are all recognizable from both the simulated and reconstructed temperatures. The anomalies associated with the LIA and the modern warming simulated by the model is in good consistency with the reconstructed counterpart. In particular during the Maunder sun-spot minimum (1670£­1710 A.D.), both the simulated and reconstructed temperature anomalies reach their minima without any phase difference. But in the earlier MWP, significant discrepancies exist between the simulation and the reconstruction, which might reflect the degrading quality of the reconstruction data. The range of the simulated anomalies (1.62 K) is comparable with that of reconstructed (2.0 K). Diagnosis of the model results indicates that, during the last millennium, variations in solar radiation and volcanic activity are the main controlling factors on regional temperature change, while in the recent 100 years, the change of the concentration of greenhouse gases plays most important role in explaining

  12. Coherent anti-phasing between solar forcing and tropical Pacific climate over the past millennium: derivation and implications

    NASA Astrophysics Data System (ADS)

    Using a compilation of the most recent, high-resolution proxy data from the tropics, and a state-of-the-art climate reconstruction technique (RegEM iTTLS; Emile-Geay et al, submitted), we reconstruct sea-surface temperature (SST) in the central equatorial Pacific (NINO3.4 region) over the past millennium. Using frozen network experiments and pseudoproxy validation, the reconstruction is found skillful back to 1150 C.E., with inevitable amplitude reduction before 1500 C.E. due to the paucity of proxy predictors. Despite this caveat, wavelet coherency analysis reveals a marked anticorrelation between solar forcing (as estimated from cosmogenic isotope concentrations; Bard et al., 2007; Steinhilber et al., 2009) and the reconstructed NINO3.4 in the ~sim205-year spectral range (DeVries cycle). The phase angle between both signals is 156 ± 33o in this range, indicating that periods of high solar irradiance coincide with cool conditions in the NINO3.4 region, with time lag of 14 ± 19 years. We find this result robust to the reconstruction method, estimate of solar forcing, or analysis method used to estimate the phasing. We then discuss the implication of this result for the response of tropical Pacific climate to radiative forcing. While the anti-phasing seems to favor the ``ocean dynamical thermostat'' hypothesis of Clement et al [1996], this feedback appears subdued in most IPCC-class coupled general circulation models (CGCMs), where it is almost completely compensated by changes in the Pacific trade winds, linked to changes in the vertical structures of atmospheric moisture and temperature (Knutson & Manabe 1995; Held & Soden 2006; Vecchi et al. 2006). If the reconstruction is correct that past NINO3.4 SSTs have varied out of phase with solar irradiance on bicentennial scales, this would pose a new challenge both for CGCM simulations and for our understanding of the equatorial Pacific response to radiative forcing Clement, A.

    The NASA Solar Electric Propulsion Technology Applications Readiness Program (NSTAR) will provide a single-string primary propulsion system to NASA's New Millennium Deep Space 1 Mission which will perform comet and asteroid flybys in the years 1999 and 2000. The propulsion system includes a 30-cm diameter ion thruster, a xenon feed system, a power processing unit, and a digital control and interface unit. A total of four engineering model ion thrusters, three breadboard power processors, and a controller have been built, integrated, and tested. An extensive set of development tests has been completed along with thruster design verification tests of 2000 h and 1000 h. An 8000 h Life Demonstration Test is ongoing and has successfully demonstrated more than 6000 h of operation. In situ measurements of accelerator grid wear are consistent with grid lifetimes well in excess of the 12,000 h qualification test requirement. Flight hardware is now being assembled in preparation for integration, functional, and acceptance tests.

  14. The worst North American drought year of the last millennium: 1934

    During the summer of 1934, over 70% of western North America experienced extreme drought, placing this summer far outside the normal range of drought variability and making 1934 the single worst drought year of the last millennium. Strong atmospheric ridging along the West Coast suppressed cold season precipitation across the Northwest, Southwest, and California, a circulation pattern similar to the winters of 1976-1977 and 2013-2014. In the spring and summer, the drying spread to the Midwest and Central Plains, driven by severe precipitation deficits downwind from regions of major dust storm activity, consistent with previous work linking drying during the Dust Bowl to anthropogenic dust aerosol forcing. Despite a moderate La Niña, contributions from sea surface temperature forcing were small, suggesting that the anomalous 1934 drought was primarily a consequence of atmospheric variability, possibly amplified by dust forcing that intensified and spread the drought across nearly all of western North America.

  15. Implications of high amplitude atmospheric CO2 fluctuations on past millennium climate change

    Stomatal frequency analysis of leaves of land plants preserved in peat and lake deposits can provide a proxy record of pre-industrial atmospheric CO2 concentration complementary to measurements in Antarctic ice cores. Stomatal frequency based CO2 trends from the USA and NW European support the presence of significant CO2 variability during the first half of the last millennium (Kouwenberg et al., 2005; Wagner et al., 2004; van Hoof et al., 2008). The timing of the most significant perturbation in the stomata records (1200 AD) is in agreement with an observed CO2 fluctuation in the D47 Antarctic ice-core record (Barnola et al., 1995; van Hoof et al., 2005). The amplitude of the stomatal frequency based CO2 changes (> 34ppmv) exceeds the maximum amplitude of CO2 variability in the D47 ice core (< 10 ppmv). A modelling experiment taking into account firn-densification based smoothing processes in the D47 ice core proved, however, that the amplitude difference between the stomata record and the D47 ice-core can be explained by natural smoothing processes in the ice (van Hoof et al., 2005). This observation gives credence to the existence of high-amplitude CO2 fluctuations during the last millennium and suggests that high resolution ice core CO2 records should be regarded as a smoothed representation of the atmospheric CO2 signal. In the present study, potential marine and terrestrial sources and sinks associated with the observed atmospheric CO2 perturbation will be discussed. The magnitude of the observed CO2 variability implies that inferred changes in CO2 radiative forcing are of a similar magnitude as variations ascribed to other forcing mechanisms (e.g. solar forcing and volcanism), therefore challenging the IPCC concept of CO2 as an insignificant preindustrial climate forcing factor.

  18. Sutherland's legacy in the new millennium: the osteopathic cranial model and modern osteopathy.

    Bordoni, Bruno; Zanier, Emiliano

    2015-01-01

    The concept of cranial osteopathy was introduced by W. G. Sutherland, DO, and became the foundation for setting the rules for use of skull palpation and many other techniques in the many types of dysfunctional patterns that craniosacral therapy treats. Sutherland's theories enabled modern osteopathy to develop and improve. The mechanism of primary respiration as well as the motion of neurocranial and viscerocranial sutures are phenomena intrinsic to the field and can be found in every living organism, independent of thoracic breathing and cardiac impulse. The sphenobasilar synchondrosis (ie, the joint between the base of the occiput and the body of the sphenoid bone) is the pillar supporting the concepts of craniosacral therapy. This article compares the cranial model devised by Sutherland with the present, relevant scientific research, aiming at clarifying the possibility of applying the craniosacral model in the new millennium.

    Despite numerous investigations, the dynamical origins of the Medieval Climate Anomaly and the Little Ice Age remain uncertain. A major unresolved issue relating to internal climate dynamics is the mode and tempo of Atlantic meridional overturning circulation variability, and the significance of decadal-to-centennial scale changes in Atlantic meridional overturning circulation strength in regulating the climate of the last millennium. Here we use the time-constrained high-resolution local radiocarbon reservoir age offset derived from an absolutely dated annually resolved shell chronology spanning the past 1,350 years, to reconstruct changes in surface ocean circulation and climate. The water mass tracer data presented here from the North Icelandic shelf, combined with previously published data from the Arctic and subtropical Atlantic, show that surface Atlantic meridional overturning circulation dynamics likely amplified the relatively warm conditions during the Medieval Climate Anomaly and the relatively cool conditions during the Little Ice Age within the North Atlantic sector.

    The last Millennium is the best documented climate period affected by variations in external forcing and internal dynamics in a highly nonlinear climate system. According to that the Indian Monsoon and its high variability on different time scales plays an important role, studied in the interdisciplinary HIMPAC project (Himalaya - Modern and Past Climates). In order to understand the driving mechanisms, feedbacks and amplifiers regarding the monsoon variability of the last 1.200 years, the five ensemble members of the full forced simulation of the Millennium experiment (Jungclaus et al., 2010), using the coupled COSMOS Earth System Model (ECHAM5/JSBACH-MPIOM/HAMOCC) in a T31L19 spatial resolution, have been statistically analysed to detect strong wet and dry periods of monsoon rainfall within the All India Monsoon Rainfall Region. Later the selected periods of extreme rainfall events have been simulated in a higher spatial resolution with the atmosphere-only model ECHAM5 in a T63L31 spatial resolution. The focus is on the monsoon variability of the selected 200-years long time slices within the Medieval Climate Optimum (MWP; 900-1100 AD), the Little Ice Age (LIA; 1515-1715 AD) and the Preindustrial (PI; 1800-2000 AD). The relative annual rainfall anomalies simulated by ECHAM5 model show drier (wetter) conditions over India during the MWP (LIA) compared to the PI. The spatial EOF variance patterns of the summer monsoon rainfall in the MWP are more pronounced in the lower resolved T31L19 Millennium simulation according to the higher amount of simulated rainfall whereas the differentiation of the patterns is better in the T63L31 ECHAM5 simulation especially in the Himalayas due to the better representation of the mountains. Furthermore the simulations have been also compared with paleoclimatic reconstructions based on proxy data from different archives (Bhattacharya et al., 2007, Chauhan et al., 2000, Denniston et al., 2000, Ely et al., 1999, Kar et al., 2002, Ponton

    Portion sizes of foods have been noticably increasing in recent years, but when did this trend begin? If art imitates life and if food portions have been generally increasing with time, we might expect this trend to be reflected in paintings that depict food. Perhaps the most commonly painted meal has been that of Jesus Christ's Last Supper, chronicled in the New Testament of the Bible. A CAD-CAM analysis of the relative food-to-head ratio in 52 representative paintings of the Last Supper showed that the relative sizes of the main dish (entree) (r=0.52, P=0.002), bread (r=0.30, P=0.04), and plates (r=0.46, P=0.02) have linearly increased over the past millennium.

    2014-11-01

    The Indian Ocean Zonal Mode (IOZM) has gained considerable attention in the past decade due to its role in causing widespread flooding and droughts in the continents and islands surrounding the Indian Ocean. The IOZM has also been observed to vary on a low-frequency (multi-decadal) basis, making its behavior important to understand both for mid-range 21st century climate prediction and for paleoclimate studies. Despite efforts to reconstruct the IOZM using corals and other high-resolution proxies, nonstationarities in the response of paleoclimate proxies to the IOZM have also been noted, raising the possibility that the IOZM may be difficult to reconstruct or to predict in the long-term. It is therefore critical to assess the low-frequency component of the IOZM in observed, modeled, and paleoclimate data from the Indian Ocean region in order to identify nonstationary behavior and to assess its role in low-frequency climate variations. We present an analysis of low-frequency and nonstationary behavior in the IOZM on multi-decadal to centennial timescales using a combination of modeled, observed, and proxy reconstructions of δ18O/δDprecip. In order to assess multiple timescales of low-frequency variability, we focus on two key time periods: the historical period (1870-2003), and the past millennium (1000 C.E.-present). We find significant nonstationarities in the relationships between the IOZM, precipitation amount, and δ18Oprecip/δDprecip during the historical period. These relationships vary on a multi-decadal basis in our model and in observed/reanalysis datasets. Air-sea interactions in the Indo-Pacific Warm Pool and teleconnections to the Pacific Ocean, as well as the phase of the IOZM itself, may contribute to this nonstationary behavior. We examine the potential ramifications of nonstationary IOZM behavior using a synthesis of spatially distributed proxy archives of δ18Oprecip/δDprecip from both sides of the IOZM region spanning the past millennium.

New second-generation antihistamines, which act as good symptomatic drugs, emerged and were commercialized over the last decade. Old and new drugs that may interfere with the pathophysiology of the disease, such as cyclosporine and omalizumab have been developed and used as treatments. The purpose of this article is to describe the current state of knowledge on aspects of chronic urticaria such as, pathophysiology, diagnosis and the current therapeutic approach proposed in the literature.

    This study examines the extent and type of sexually harassing behavior or intimidations unmarried adolescent girls experienced on their way to school, college or social visits and type of perpetrators in victims' view in rural Bangladesh using data of the 2004 National Nutrition Programme baseline survey. The survey collected self-reported data on sexual harassments of 5,106 girls aged 13-19 years selected randomly. Results reveal that gendered harassments were experienced by 35% of the girls, unwanted sexual attentions by 34%, and sexual intimidations by 14%, yielding prevalence of sexual harassments of any type 43%. Higher girls' education and household economic status heightened their risks of being harassed. Perpetrators were male young spoilt bullies (64%), neighborhood youths (30%), students (22%) and hoodlums (6%). High prevalence of sexual harassments mirrors vulnerability of adolescent girls in the community and deserves to be tackled to achieve millennium development goals (MDGs) in gender equality in health and social development.

    The world has made substantial progress in reducing maternal and child mortality, but many countries are projected to fall short of achieving their Millennium Development Goals (MDGs) 4 and 5 targets. The major objective of this paper is to examine progress in Pakistan in reducing maternal and child mortality and malnutrition over the last two decades. Data from recent national and international surveys suggest that Pakistan lags behind on all of its MDGs related to maternal and child health and, for some indicators especially related to nutrition, the situation has worsened from the baseline of 1990. Progress in addressing key social determinants such as poverty, female education and empowerment has also been slow and unregulated population growth has further compromised progress. There is a need to integrate the various different sectors and programmes to achieve the desired results effectively and efficiently as many of the determinants and influencing factors are outside the health sector.

    National professional associations of obstetrics and gynecology characteristically begin as learned societies holding regular conferences for the presentation and discussion of new research results, and progress to regulating the activities of their members in the public interest (e.g. admission examinations, setting standards). However, they can offer much more to their nation's health by contributing directly to improvements in health care and influencing governmental decisions in favor of the health of women and babies. The International Federation of Gynecology and Obstetrics (FIGO), through the Leadership in Obstetrics and Gynecology for Impact and Change (LOGIC) initiative, is developing the capacity of national professional associations in Africa and Asia, so that they can contribute to improving clinical practice and influence national health policy toward achieving Millennium Development Goal 5.

    Any assessment of future climate change requires knowledge of the full range of natural variability in the El Niño/Southern Oscillation (ENSO) phenomenon. Here we splice together fossil-coral oxygen isotopic records from Palmyra Island in the tropical Pacific Ocean to provide 30-150-year windows of tropical Pacific climate variability within the last 1,100 years. The records indicate mean climate conditions in the central tropical Pacific ranging from relatively cool and dry during the tenth century to increasingly warmer and wetter climate in the twentieth century. But the corals also document a broad range of ENSO behaviour that correlates poorly with these estimates of mean climate. The most intense ENSO activity within the reconstruction occurred during the mid-seventeenth century. Taken together, the coral data imply that the majority of ENSO variability over the last millennium may have arisen from dynamics internal to the ENSO system itself. PMID:12867972

Although Gratzel began his research well before nanotechnology had the "buzz" that it does today, the mesoscopic thin films he has developed have paved the way for generations of scientists to exploit the nanoscale for energy conversion. In addition to practical application, his research has led to a deeper understanding of photoinitiated charge-transfer processes at semiconductor interfaces.

    While tree ring and lake sediment core studies have revealed a great deal about North Pacific (e.g. Alaska) surface temperature variability over the past millennium, we do not have an equivalent understanding of North Pacific hydroclimate variability or temperatures at high elevations. A millennial-length precipitation proxy record is needed to place late 20th century Alaskan precipitation increases into longer context, and to evaluate hydroclimate changes during the Little Ice Age and Medieval Climate Anomaly. High-elevation summer temperature records would be valuable for understanding the sensitivity of Alaskan glaciers to past warm and cool periods. Here we present an overview of the new Denali Ice Core record collected from the summit plateau (4000 m a.s.l.) of Mt. Hunter (63° N, 151° W) in Denali National Park, Alaska. Two parallel ice cores were collected to bedrock (208 m in length) in May-June 2013, sampled using the Dartmouth continuous melter system, and analyzed for major ions, trace elements, particle concentration and size distribution, and stable isotope ratios at Dartmouth and the Universities of Maine and New Hampshire. The cores are dated using robust annual oscillations in dust elements, methanesulfonate, ammonium, and stable isotopes, and validated using major volcanic eruptions recorded as sulfate, chloride and heavy metal spikes, and the 1963 nuclear weapons testing 137Cs spike. Preliminary analyses indicate a significant increase in both summer temperature and annual accumulation over the 20th century, and significant relationships with major ocean-atmospheric modes including the Pacific Decadal Oscillation. We compare the new Denali record to the Eclipse Icefield and Mt. Logan ice core records and develop composite records of North Pacific hydroclimate and atmospheric circulation variability over the past millennium.

    El Niño-Southern Oscillation is the major source of interannual rainfall variability in the Australian region, with the strongest influence over eastern Australia. The strength of this regional ENSO-rainfall teleconnection varies in the observational record. Climate model simulations of the "last millennium" (850-1850 C.E.) can be used to quantify the natural variability of the relationship between ENSO and Australian rainfall on decadal and longer time scales, providing a baseline for evaluating future projections. In this study, historical and last millennium (LM) simulations from six models were obtained from the Coupled Model Intercomparison Project Phase 5 and Palaeoclimate Modelling Intercomparison Project Phase 3. All models reproduce the observed negative correlation between September to February (SONDJF) eastern Australian rainfall and the NINO3.4 index, with varying skill. In the LM simulations, all models produce decadal-scale cooling over eastern Australia in response to volcanic forcing, as well as a long-term cooling trend. Rainfall variability over the same region is not strongly driven by external forcing, with each model simulating rainfall anomalies of different phase and magnitude. SONDJF eastern Australian rainfall is strongly correlated with ENSO in the LM simulations for all models, although some models simulate periods when the teleconnection weakens substantially for several decades. Changes in ENSO variance play a role in modulating the teleconnection strength, but are not the only factor. The long-term average spatial pattern of the ENSO-Australian rainfall teleconnection is similar in the LM and historical simulations, although the spatial pattern varies over time in the LM simulations.

    Recent severe El Niño-Southern Oscillation (ENSO) events have highlighted the importance of understanding the mechanisms driving ENSO variability and how ENSO relates to extreme precipitation anomalies. Expanding the record of ENSO-driven precipitation anomalies over the last millennium through paleoclimate reconstructions illuminates how ENSO has varied in the past through periods of relatively enhanced and reduced radiative forcing, namely the Medieval Climate Anomaly (MCA) and the Little Ice Age (LIA). Modern precipitation anomalies in East Java, Indonesia are strongly correlated to variations in ENSO, where La Niña events correspond to positive precipitation anomalies (Hendon, 2003, Journal of Climate). We present the first record of runoff events from lake sediment deposits in East Java, Indonesia spanning the last millennium, which historically occur during strong La Niña events. Our record reveals significant variations in East Java flooding frequency, with more frequent floods occurring from 850 to 1350 CE and after 1800 CE. This pattern is also observed in surface runoff records from the eastern tropical Pacific (Moy et al., 2002, Nature; Conroy et al., 2008, Quaternary Science Reviews), which lie in a region where modern positive precipitation anomalies are closely tied to El Niño events. Extreme rainfall events occurring on both sides of the tropical Pacific on centennial timescales may indicate that both El Niño and La Niña activity were higher during the Medieval Climate Anomaly and the most recent two centuries, when radiative forcing was high, and that ENSO activity was reduced during the Little Ice Age, when radiative forcing was weak.

    Determining past changes in the amplitude, frequency and teleconnections of the El Nio Southern Oscillation (ENSO) is important for understanding its potential sensitivity to future anthropogenic climate change. Palaeo-reconstructions from proxy records provide long-term information of ENSO interactions with the background climatic state through time. However, it remains unclear how ENSO characteristics have changed through time, and precisely which signals proxies record. Proxy interpretations are underpinned by the assumption of stationarity in relationships between local and remote climates, and often utilise archives from single locations located in the Pacific Ocean to reconstruct ENSO histories. Here, we investigate the stationarity of ENSO teleconnections using the Last Millennium experiment of CMIP5 (Coupled Model Intercomparison Project phase 5) (Taylor et al., 2012). We show that modelled ENSO characteristics vary on decadal- to centennial-scales, resulting from internal variability and external forcings, such as tropical volcanic eruptions. Furthermore, the relationship between ENSO conditions and local climates across the Pacific basin varies throughout the Last Millennium. Results show the stability of teleconnections is regionally dependent and proxies may reveal complex changes in teleconnected patterns, rather than large-scale changes in base ENSO characteristics. As such, proxy insights into ENSO likely require evidence to be synthesised over large spatial areas in order to deconvolve changes occurring in the NINO3.4 region from those pertaining to proxy-relevant local climatic variables. To obtain robust histories of the ENSO and its remote impacts, we recommend interpretations of proxy records should be considered in conjunction with palaeo-reconstructions from within the Central Pacific

    A new tree-ring reconstruction of the Palmer Drought Severity Index (PDSI) for Mesoamerica from AD 771 to 2008 identifies megadroughts more severe and sustained than any witnessed during the twentieth century. Correlation analyses indicate strong forcing of instrumental and reconstructed June PDSI over Mesoamerica from the El Niño/Southern Oscillation (ENSO). Spectral analyses of the 1,238-year reconstruction indicate significant concentrations of variance at ENSO, sub-decadal, bi-decadal, and multidecadal timescales. Instrumental and model-based analyses indicate that the Atlantic Multidecadal Oscillation is important to warm season climate variability over Mexico. Ocean-atmospheric variability in the Atlantic is not strongly correlated with the June PDSI reconstruction during the instrumental era, but may be responsible for the strong multidecadal variance detected in the reconstruction episodically over the past millennium. June drought indices in Mesoamerica are negatively correlated with gridded June PDSI over the United States from 1950 to 2005, based on both instrumental and reconstructed data. Interannual variability in this latitudinal moisture gradient is due in part to ENSO forcing, where warm events favor wet June PDSI conditions over the southern US and northern Mexico, but dryness over central and southern Mexico (Mesoamerica). Strong anti-phasing between multidecadal regimes of tree-ring reconstructed June PDSI over Mesoamerica and reconstructed summer (JJA) PDSI over the Southwest has also been detected episodically over the past millennium, including the 1950-1960s when La Niña and warm Atlantic SSTs prevailed, and the 1980-1990s when El Niño and cold Atlantic SSTs prevailed. Several Mesoamerican megadroughts are reconstructed when wetness prevailed over the Southwest, including the early tenth century Terminal Classic Drought, implicating El Niño and Atlantic SSTs in this intense and widespread drought that may have contributed to social

    The salinity and temperature of the Florida Current are key parameters affecting the transport of heat into the North Atlantic, yet little is known about their variability on centennial timescales. Here we report replicated, high-resolution foraminiferal records of Florida Current surface hydrography for the last millennium from two coring sites, Dry Tortugas and the Great Bahama Bank. The oxygen isotopic composition of Florida Current surface water (δ18Ow) near Dry Tortugas increased 0.4‰ during the course of the Little Ice Age (LIA) (˜1200-1850 A.D.), equivalent to a salinity increase of 0.8-1.5. On the Great Bahama Bank, where surface waters are influenced by the North Atlantic subtropical gyre, δ18Ow increased by 0.3‰ during the last 200 years. Although a portion (˜0.1‰) of this shift may be an artifact of anthropogenically driven changes in surface water ΣCO2, the remaining δ18Ow signal implies a 0.4-1 increase in salinity after 200 years B.P. The simplest explanation of the δ18Ow data is southward migration of the Atlantic Hadley circulation during the LIA. Scaling of the δ18Ow records to salinity using the modern low-latitude δ18Ow-S slope produces an unrealistic reversal in the salinity gradient between the two sites. Only if δ18Ow is scaled to salinity using a high-latitude δ18Ow-S slope can the records be reconciled. Variable atmospheric 14C paralleled Dry Tortugas δ18Ow, suggesting that solar irradiance paced centennial-scale migration of the Inter-Tropical Convergence Zone and changes in Florida Current salinity during the last millennium.

    The last Millennium is the best documented climate period affected by variations in external forcing and an internal variability in the highly nonlinear climate system. According to that the Indian Summer Monsoon and its high variability on different time scales plays an important role, studied in the interdisciplinary HIMPAC project (Himalaya - Modern and Past Climates). In order to understand the forcing mechanisms, feedbacks and amplifiers concerning monsoon variability of the last 1000 years, the five ensemble members of the full forced simulation of the Millennium experiment (Jungclaus, J. et al., 2010), using the coupled COSMOS Earth System Model (ECHAM5/JSBACH-MPIOM/HAMOCC) in a T31L19 spatial resolution, have been statistically analyzed to detect strong wet and dry periods of monsoonal rainfall due to interannual rainfall anomalies and special monsoon indices within the South Asian Monsoon region. Later the selected periods of extreme rainfall events have been simulated in a higher spatial resolution with the uncoupled atmosphere version of COSMOS Earth System Model (ECHAM5) in a T63L31 resolution. The focus is on the monsoon variability of 200-years-long time slices within the Medieval Climate Optimum (900-1100 AD), the Little Ice Age (1500-1700 AD) and the Preindustrial (1800-2000). A comparison with paleoclimatic reconstructions from Dandak and Jhumar cave record (Sinha, A. et al., 2011) helps to verify the model results, and the model has been used to check the consistency of the proxy data. I addition high resolution regional climate model simulations with COSMO-CLM will be carried out for the selected time slices driven by the ECHAM5 simulation results.

    Pakistan has third highest burden of maternal and children mortality across the globe. This grim situation is further intensified by flaws of planning and implementation set forth in health sector. Natural calamities (earth quakes, floods), disease outbreaks and lack of awareness in different regions of country also further aggravate this situation. Despite of all these limitations, under the banner of Millennium Development Goals (MDGs) a special focus and progress in addressing maternal health issue (set as goal 5) has been made over the last decade. In this review, improvement and short falls pertaining to Goal 5 Improve maternal health have been analyzed in relation to earlier years. A decline in maternal mortality ratio (MMR) (490 maternal deaths in 1990 to 260 maternal deaths per 100,000 women in 2010) is observed. Reduction in MMR by three quarters was not achieved but a decline from very high mortality to high mortality index was observed. Increase usage of contraceptives (with contraceptive prevalence rate of 11.8 in 1990 to 37 in 2013) also shed light on women awareness about their health and social issues. Based on progress level assessment (WHO guidelines),access of Pakistani women to universal reproductive health unit falls in moderate category in 2010 as compared to earlier low access in 1990. From the data it looks that still a lot of effort is required for achieving the said targets. However, keeping in view all challenges, Pakistan suffered in the said duration, like volatile peace, regional political instability, policy implementation constrains, population growth, this slow but progressive trend highlight a national resilience to address the havoc challenge of maternal health. These understandings and sustained efforts will significantly contribute a best possible accomplishment in Millennium Development Goal 5 by 2015. PMID:25252492

    We use proxy data and modeled data from 1000 year model simulations with a variety of climate forcings to examine the occurrence of severe event of persistent drought over eastern China during the last millennium and diagnose the mechanisms. Results show that the model was able to roughly simulate most of these droughts over the study area during the last millennium such as those that occurred during the periods of 1123-1152, 1197-1223, 1353-1363, 1428-1449, 1479-1513, and 1632-1645. Our analyses suggest that these six well-captured droughts may caused by the East Asian summer monsoon (EASM) weakening. Study on the wavelet transform and spectral analysis reveals these events occurred all at the statistically significant 15-35-year timescale. A modeled data intercomparison suggests the possibility that solar activity may be the primary driver in the occurrence of the 1129-1144, 1354-1365, 1466-1491 and 1631-1648 droughts as identified by the model. However another possibility that these events may be related to internal variability cannot be excluded. Although the El Niño-Southern Oscillation (ENSO) plays an important role in monsoon variability, a temporally consistent relationship between the droughts and SST pattern in the Pacific Ocean could not be found either in the modeled or proxy data. Our analyses also indicate that large volcanic eruptions play a role as an amplifier in the drought of 1631-1648 and caused the droughts of 1830-1853 and 1958-1976, which was identified by the model.

  1. Enhanced Formation Flying for the Earth Observing-1 (EO-1) New Millennium Mission

    With scientific objectives for Earth observation programs becoming more ambitious and spacecraft becoming more autonomous, the need for new technical approaches on the feasibility of achieving and maintaining formations of spacecraft has come to the forefront. The trend to develop small low cost spacecraft has led many scientists to recognize the advantage of flying several spacecraft in formation, an example of which is shown in the figure below, to achieve the correlated instrument measurements formerly possible only by flying many instruments on a single large platform. Yet, formation flying imposes additional complications on orbit maintenance, especially when each spacecraft has its own orbit requirements. However, advances in automation proposed by GSFC Codes 550 and 712 allow more of the burden in maneuver planning and execution to be placed onboard the spacecraft, mitigating some of the associated operational concerns. The purpose of this analysis is to develop the fundamentals of formation flying mechanics, concepts for understanding the relative motion of free flying spacecraft, and an operational control theory for formation maintenance of the Earth Observing-1 (EO-l) spacecraft that is part of the New Millennium. Results of this development can be used to determine the appropriateness of formation flying for a particular case as well as the operational impacts. Applications to the Mission to Planet Earth (MTPE) Earth Observing System (EOS) and New Millennium (NM) were highly considered in analysis and applications. This paper presents the proposed methods for the guidance and control of the EO-1 spacecraft to formation fly with the Landsat-7 spacecraft using an autonomous closed loop three axis navigation control, GPS, and Cross link navigation support. Simulation results using various fidelity levels of modeling, algorithms developed and implemented in MATLAB, and autonomous 'fuzzy logic' control using AutoCon will be presented.

    OBJECTIVES: Functional gastrointestinal disorders occur more frequently among deployed veterans, although studies evaluating the relative impact of risk factors, including stress and antecedent infectious gastroenteritis (IGE), are limited. We examined risk factors for new-onset irritable bowel syndrome (IBS) among active duty participants in the military's Millennium Cohort Study. METHODS: Medical encounter data from 2001 to 2009, limited to Cohort members on active duty, were used to identify incident IBS cases (any and highly probable). IGE was identified using medical encounter or self-report. Covariate data were obtained from the Millennium Cohort Study surveys and analyzed using Cox proportional hazards methods. RESULTS: Overall, 41,175 Cohort members met the eligibility criteria for inclusion and 314 new-onset cases of IBS were identified among these. Significant risk factors (adjusted hazard ratio, 95% confidence interval) included antecedent IGE (2.05, 1.53–2.75), female gender (1.96, 1.53–2.52), number of life stressors (1: 1.82, 1.37–2.41; 2: 2.86, 2.01–4.06; 3+: 6.69, 4.59–9.77), and anxiety syndrome (1.74, 1.17–2.58). Limited to highly probable IBS, a stronger association with antecedent IGE was observed, particularly when based on medical encounter records (any IGE: 2.20, 1.10–4.43; medical encounter IGE only: 2.84, 1.33–6.09). Precedent anxiety or depression and IGE interacted with increased IBS risk compared with IGE alone. CONCLUSIONS: These results confirm previous studies on the association between sociodemographic or life stressors and IBS. IGE was significantly associated with IBS risk. Whether deployed or not, US service members often encounter repeated exposure to high levels of stress, which, combined with other environmental factors such as IGE, may result in long-term debilitating functional gastrointestinal disorders.

    El Niño-Southern Oscillation is the major source of interannual rainfall variability in the Australian region, with the strongest influence over eastern Australia. The strength of this regional ENSO-rainfall teleconnection varies in the observational record. Climate model simulations of the "last millennium" (850-1850 C.E.) can be used to quantify the natural variability of the relationship between ENSO and Australian rainfall on decadal and longer time scales, providing a baseline for evaluating future projections. In this study, historical and last millennium (LM) simulations from six models were obtained from the Coupled Model Intercomparison Project Phase 5 and Palaeoclimate Modelling Intercomparison Project Phase 3. All models reproduce the observed negative correlation between September to February (SONDJF) eastern Australian rainfall and the NINO3.4 index, with varying skill. In the LM simulations, all models produce decadal-scale cooling over eastern Australia in response to volcanic forcing, as well as a long-term cooling trend. Rainfall variability over the same region is not strongly driven by external forcing, with each model simulating rainfall anomalies of different phase and magnitude. SONDJF eastern Australian rainfall is strongly correlated with ENSO in the LM simulations for all models, although some models simulate periods when the teleconnection weakens substantially for several decades. Changes in ENSO variance play a role in modulating the teleconnection strength, but are not the only factor. The long-term average spatial pattern of the ENSO-Australian rainfall teleconnection is similar in the LM and historical simulations, although the spatial pattern varies over time in the LM simulations.

    The introduction of dairying was a critical step in early agriculture, with milk products being rapidly adopted as a major component of the diets of prehistoric farmers and pottery-using late hunter-gatherers. The processing of milk, particularly the production of cheese, would have been a critical development because it not only allowed the preservation of milk products in a non-perishable and transportable form, but also it made milk a more digestible commodity for early prehistoric farmers. The finding of abundant milk residues in pottery vessels from seventh millennium sites from north-western Anatolia provided the earliest evidence of milk processing, although the exact practice could not be explicitly defined. Notably, the discovery of potsherds pierced with small holes appear at early Neolithic sites in temperate Europe in the sixth millennium BC and have been interpreted typologically as 'cheese-strainers', although a direct association with milk processing has not yet been demonstrated. Organic residues preserved in pottery vessels have provided direct evidence for early milk use in the Neolithic period in the Near East and south-eastern Europe, north Africa, Denmark and the British Isles, based on the δ(13)C and Δ(13)C values of the major fatty acids in milk. Here we apply the same approach to investigate the function of sieves/strainer vessels, providing direct chemical evidence for their use in milk processing. The presence of abundant milk fat in these specialized vessels, comparable in form to modern cheese strainers, provides compelling evidence for the vessels having being used to separate fat-rich milk curds from the lactose-containing whey. This new evidence emphasizes the importance of pottery vessels in processing dairy products, particularly in the manufacture of reduced-lactose milk products among lactose-intolerant prehistoric farming communities.

    We present the first millennial-length gridded field reconstruction of annual temperature for China, and analyze the reconstruction for spatiotemporal changes and associated uncertainties, based on a network of 415 well-distributed and accurately dated climatic proxy series. The new reconstruction method is a modified form of the point-by-point regression (PPR) approach. The main difference is the incorporation of the "composite plus scale" (CPS) and "Regularized errors-in-variables" (EIV) algorithms to allow for the assimilation of various types of the proxy data. Furthermore, the search radius is restricted to a grid size; this restriction helps effectively exclude proxy data possibly correlated with temperature but belonging to a different climate region. The results indicate that: 1) the past temperature record in China is spatially heterogenic, with variable correlations between cells in time; 2) the late 20th century warming in China probably exceeds mean temperature levels at any period of the past 1000 years, but the temperature anomalies of some grids in eastern China during the Medieval climate anomaly period are warmer than during the modern warming; 3) the climatic variability in the eastern and western regions of China was not synchronous during much of the last millennium, probably due to the influence of the Tibetan Plateau. Our temperature reconstruction may serve as a reference to test simulation results over the past millennium, and help to finely analyze the spatial characteristics and the driving mechanism of the past temperature variability. However, the lower reconstruction skill scores for some grid points underline that the present set of available proxy data series is not yet sufficient to accurately reconstruct the heterogeneous climate of China in all regions, and that there is the need for more highly resolved temperature proxies, particularly in the Tibetan Plateau.

    BORDERLINE PERSONALITY DISORDER (BPD) IS A COMPLEX AXIS II Phenomenon that is typically described in a psychological or psychiatric context. In this article, we translate the various aspects of BPD to the primary care setting. Previous work in this area has explored specific relationships between BPD and individual medical disorders or between BPD and general somatic symptoms, but the synthesis of these findings and their augmentation with cogent psychological theory is new to the field. Specifically, we highlight the prevalence rate of BPD in the primary care setting, the effects on healthcare utilization, the themes of somatic preoccupation and somatization disorder, several medical syndromes that illustrate the dynamics of the disorder in the medical setting, and the relationship of BPD to disability. We believe that the BPD concept needs to extend beyond its traditional psychological/psychiatric borders to include the subset of BPD patients with somatic symptoms who are seen in primary care settings.

    IMPORTANCE Persons with type 2 diabetes mellitus (T2DM) are at increased risk for decline in cognitive function, reduced brain volume, and increased white matter lesions in the brain. Poor control of blood pressure (BP) and lipid levels are risk factors for T2DM-related cognitive decline, but the effect of intensive treatment on brain function and structure is unknown. OBJECTIVE To examine whether intensive therapy for hypertension and combination therapy with a statin plus a fibrate reduces the risk of decline in cognitive function and total brain volume (TBV) in patients with T2DM. DESIGN, SETTING, AND PARTICIPANTS A North American multicenter clinical trial including 2977 participants without baseline clinical evidence of cognitive impairment or dementia and with hemoglobin A1c (HbA1c) levels less than 7.5% randomized to a systolic BP goal of less than 120 vs less than 140 mm Hg (n = 1439) or to a fibrate vs placebo in patients with low-density lipoprotein cholesterol levels less than 100 mg/dL (n = 1538). Participants were recruited from August 1, 2003, through October 31, 2005, with the final follow-up visit by June 30, 2009. MAIN OUTCOME MEASURES Cognition was assessed at baseline and 20 and 40 months. A subset of 503 participants underwent baseline and 40-month brain magnetic resonance imaging to assess for change in TBV and other structural measures of brain health. RESULTS Baseline mean HbA1c level was 8.3%; mean age, 62 years; and mean duration of T2DM, 10 years. At 40 months, no differences in cognitive function were found in the intensive BP-lowering trial or in the fibrate trial. At 40 months, TBV had declined more in the intensive vs standard BP-lowering group (difference, −4.4 [95% CI, −7.8 to −1.1] cm3; P = .01). Fibrate therapy had no effect on TBV compared with placebo. CONCLUSIONS AND RELEVANCE In participants with long-standing T2DM and at high risk for cardiovascular events, intensive BP control and fibrate therapy in the presence of

    Whole human genome sequencing of individuals is becoming rapid and inexpensive, enabling new strategies for using personal genome information to help diagnose, treat, and even prevent human disorders for which genetic variations are causative or are known to be risk factors. Many of the exploding number of newly discovered genetic variations alter the structure, function, dynamics, stability, and/or interactions of specific proteins and RNA molecules. Accordingly, there are a host of opportunities for biochemists and biophysicists to participate in (1) developing tools to allow accurate and sometimes medically actionable assessment of the potential pathogenicity of individual variations and (2) establishing the mechanistic linkage between pathogenic variations and their physiological consequences, providing a rational basis for treatment or preventive care.

    In the Northern Caucasus, glacier and climatic variations over the past centuries remain insufficiently documented. In this review, we summarized the high-resolution information on glacier and climate fluctuations in the region for the past millennium and provided a synthesis of these two lines of evidence with respect to regional climate change. The key areas considered in the paper are the Elbrus area, the Teberda and Arkhyz valleys in the Western Caucasus and the Cherek Bezengiisky and Tsey valleys in the Eastern Caucasus, where the most paleoclimatic evidence has been retrieved. We focused on the fluctuation records of the ten glaciers that are best documented. To reconstruct changes in glacier length in the past, we used aerial photos, optical space images, repeated photographs and old maps. The ages of moraines were defined with the help of instrumental records, historical images, old maps, and tree-ring dating. Lichenometry was used as a supplementary tool to determine the relative ages of glacial landforms. We reviewed the collection of control points used for the lichenometric curves and determined the time limit of potential use of this method in the Caucasus to be up to one millennium. High-resolution tree-ring-based hydroclimatic reconstructions in the Northern Caucasus are presented based on the reconstruction of June-September temperature (1595-2012 CE), the mass balance reconstruction of the Garabashi Glacier (1800-2008 CE) and the runoff of the Teberda River (low-frequency variations) for May, July and August for 1850-2005 CE. The synthesis of all the available paleoclimatic records revealed several distinct climatic periods. Evidence of a warm interval (traditionally referred to as the "Arkhyz break in glaciation") preceding the Little Ice Age (LIA) in the Caucasus is based on archeological, palynological, geochemical and pedological data. However, the conclusions concerning the duration and magnitude of this warming are still vague due to the low

    High resolution multi-proxy studies of a core from Baulárvallavatn, western Iceland provide a record of climatic changes since the deposition of the Landnám tephra deposited in AD870±2. Derivation of the climate record has encountered a series of issues relating both to chronology and to proxy interpretation; but a millennial sequence of chironomid-based temperature change has been produced. Chronologically problems relate both to radiocarbon dating and tephrochronology. The lake is surrounded by loessial soils that have suffered from erosion, especially following settlement (the sedimentation rate in the lake has increased from 0.014mm yr-1 pre-settlement to 0.05mm yr-1 post-settlement). This has involved redeposition of both old carbon and tephra shards from earlier eruptions into the sediment. Thus post-Landnám radiocarbon dates are all relatively uniform between 2405-2155±30 BP. The high background levels of tephra made determination of specific post-Landnám horizons extremely difficult. Following over 550 individual shard analyses, and coupled with 137Cs dating of the uppermost sediments an age depth model was produced for the last millennium to provide a chronology for the climate proxies. Chironomid analyses at a resolution of c.10 yrs per sample showed a climatic response that is seen in the first axis of the PCA, rather than the Icelandic chironomid-July air temperature transfer function. The PCA axis correlates with winter/spring and autumn temperatures, possibly reflecting a response to summer season length rather than the expected response to July temperature. However, this has yet to be calibrated in more specific quantitative terms. The core was also subjected to ITRAX scanning; which identified key tephra horizons and reflected the relative consistency of sediment deposition over the last millennium. Oxygen isotope analyses of a limited number of diatom samples have also been undertaken and are the subject of continued research, as is diatom

    An invaluable reference for any student, scientist or administrator, using small telescopes for research. An essential collection of data and opinions for those charged with setting scientific and funding priorities. This three-volume set, The Future of Small Telescopes in the New Millennium details the essential roles that small telescopes should play in 21st century science and how their future productivity can be maximized. Over 70 experts from all corners of the international astronomical community have created a definitive reference on the present and future of "big science with small telescopes." Despite highly publicized closures of telescopes smaller than 4-m in aperture at national facilities and their omission from national science priority studies, the oft-lamented demise of the small telescope has been greatly exaggerated. In fact, the future of these workhorses of astronomy will be brighter than ever if creative steps are taken now. This three-volume set defines the essential roles that small telescopes should play in 21st century science and the ways in which a productive future for them can be realized. A wide cross-section of the astronomical community has contributed to a definitive assessment of the present and a vision for the future. Volume 1: Perceptions, Productivities, and Policies Beginning with a summary of recent national scientific priority-setting efforts, Volume 1 examines the public's and the astronomical community's own perceptions of and misconceptions about small telescope productivity. These shape the future scientific research that will be done with telescopes smaller than 4-m in aperture, and the number of astronomers that will have access to them. The Future of Small Telescopes in the New Millennium is a fundamental resource for those looking to undertake new projects with small telescopes, for those that are responsible for their operation, and for those called upon to help set scientific priorities for the coming decade.

    Paleoceanographic data show large inter-decadal cold excursions in sea-surface temperatures (SSTs) in the western subpolar gyre region and north of Iceland throughout the last millennium. A series of such events could have contributed to demise the Norse settlements over Greenland during the 13th to the 15th century due to associated deteriorating environmental conditions in the region. However, spatial extent, attribution and mechanism(s) of these cold events are not known. In this contribution, we use climate model simulations to clarify the role of the ocean and of coupled ocean-atmosphere dynamics in triggering these cold events, and to assess whether they can be explained by internal climate variability alone. Specifically, we investigate the North Atlantic-Arctic climate variability in a 1000-year control run describing an unperturbed pre-industrial climate, and in a 3-member ensemble of full-forcing transient simulations of the last millennium. Simulations are performed with the Max Planck Institute-Earth System Model for paleo-applications. In the control and transient simulations, we identified cold events of similar amplitude and duration to the reconstructed data. Spatial patterns and temporal evolutions of simulated cold events are similar in both simulation types. In the transient runs, furthermore, they do not robustly coincide with periods of strong external forcing (e.g. of major volcanic eruptions). We therefore conclude that such events can emerge because of internally-generated regional climate variability alone. Local ocean-atmosphere coupled processes in the North Atlantic subpolar gyre region appear as key part of the mechanism of simulated cold events. In particular, they are typically associated with the onset of prolonged positive sea-level pressure anomalies over the North Atlantic and associated weaker and south-eastward displaced subpolar gyre.

    We use proxy data and model data from 1000-yr model simulations with a variety of climate forcings to examine the occurrence of severe events of persistent drought over eastern China during the last millennium and diagnose the mechanisms. Results show that the model was able to simulate many aspects of the low-frequency (periods greater than 10 yr) variations of precipitation over eastern China during the last millennium, including much of the severe persistent droughts such as the 1130s drought, 1200s drought, 1350s drought, 1430s drought, 1480s drought and the drought of the late 1630s-mid 1640s. These six droughts both identified in the proxy data and model data are consistent with each other in terms of drought intensity, duration, and spatial coverage. Our analyses suggest that monsoon circulation can lock into a drought-prone mode that may last for years to decades and supports the suggestion that generally reduced monsoon in East Asia were associated with the land-sea thermal contrast. Study on the wavelet transform and spectral analysis reveals six well-captured events occurred all at the drought stages of statistically significant 15-35 yr time scale. A model data inter-comparison suggests that the solar activity are the primary driver of the 1130s drought, 1350s drought, 1480s drought and the drought of the late 1630s-mid 1640s occurrence, while the drought of 1430s was mainly caused by the internal variability of the climate system. Although the El-Niño Southern Oscillation (ENSO) plays an important role in monsoon variability, a temporally consistent relationship between the droughts and SST pattern in Pacific Oceans could not be found in the model. Our analyses also indicate that large volcanic eruptions play as amplifier in the drought of 1635-1645 and caused the model overestimates the decreasing trends in summer precipitation over eastern China during the mid-1830s and the mid-1960s.

    Investigations of past climate using fully coupled comprehensive Earth System Models are restricted by the large computational costs of these simulations. Here we present first results from an on-going simulation with the MPI-ESM-P starting in year 100 BC. The simulation is forced with changes in orbital forcing and long-term solar variations augmented by a synthetic 11-year cycle including an interactive ozone cycle. For the first time also changes in volcanic activity are implemented based on the reconstruction method by Crowley and Unterman (2012). The basis of the extended volcanic forcing in terms of aerosol optical depth and effective radius are new sulfate estimations from ice cores from Greenland (NEEM) and Antarctica (WAIS) presented by Sigl et al. (2013). Because the NEEM record only reaches back as far as 79 AD, the time until 100 BC was filled by earlier information contained in the Dye 3 and GRIP record (Clausen et al., 1997). Compared to the 2nd millennium AD, the first millennium does however show a considerably reduced amount of large explosive tropical eruptions. On hemispheric and global scale the large outbreaks around the years 530 and 740 AD are well reflected as negative temperature anomalies. The 79 AD Vesuvius eruption does not however produce a pronounced hemispheric signal. The amount of sulphate ejected into the stratosphere may have been too low for a sustained hemispheric-scale cooling. The large eruption of 530 AD (so called 'mystic cloud') is however well reflected within the temperature evolution and is more pronounced over the northern hemisphere during summertime. On longer, multi-centennial, time scales, global temperatures show a slight decrease. This decrease is more pronounced over the NH hemisphere during JJA and is caused by the decline in the TOA short wave incoming radiation. Over the extratropical SH changes in orbital forcing are not reflected in temperature trends as clearly as over the NH due to the larger oceanic and

    An invaluable reference for any student, scientist or administrator, using small telescopes for research. An essential collection of data and opinions for those charged with setting scientific and funding priorities. This three-volume set, The Future of Small Telescopes in the New Millennium details the essential roles that small telescopes should play in 21st century science and how their future productivity can be maximized. Over 70 experts from all corners of the international astronomical community have created a definitive reference on the present and future of "big science with small telescopes." Despite highly publicized closures of telescopes smaller than 4-m in aperture at national facilities and their omission from national science priority studies, the oft-lamented demise of the small telescope has been greatly exaggerated. In fact, the future of these workhorses of astronomy will be brighter than ever if creative steps are taken now. This three-volume set defines the essential roles that small telescopes should play in 21st century science and the ways in which a productive future for them can be realized. A wide cross-section of the astronomical community has contributed to a definitive assessment of the present and a vision for the future. Volume 2: The Telescopes We Use Small cost-effective optical-, radio- and space-based facilities face similar problems in scientific prioritization and funding. Volume 2 highlights how current small facilities are evolving to meet the scientific priorities and economical realities of the 21st century through standardization of instrumentation, use of off-the-shelf technology, specialization, optical improvements, new modes of scheduling, automation, and internet access. The Future of Small Telescopes in the New Millennium is a fundamental resource for those looking to undertake new projects with small telescopes, for those that are responsible for their operation, and for those called upon to help set scientific

    During the period between the mid-1990s and late 2000s Australia had suffered one of the worst droughts on record. Severe rainfall deficits affected great part of southeast Australia, causing widespread drought conditions and catastrophic bushfires. The "Millennium Drought", as it was called, was unusual in terms of its severity, duration and extent, leaving important environmental and financial damages. One of the most important drivers of Australia climate variability is the Indian Ocean dipole (IOD), that is a coupled ocean and atmosphere phenomenon in the equatorial Indian Ocean. The IOD is measured by an index (DMI) that is the difference between sea surface temperature (SST) anomalies in the western and eastern equatorial Indian Ocean. Its positive phase is characterized by lower than normal sea surface temperatures in the tropical eastern coast, and higher than normal in the tropical western Indian Ocean. Extreme positive IOD (pIOD) events are associated to severe droughts in countries located over the eastern Indian Ocean, and to severe floods in the western tropical ones. Recent research works projected that the frequency of extreme pIOD events will increase significantly over the twenty-first century and consequently, the frequency of extreme climate conditions in the zones affected by it. In this work we study the dynamics of the Indian Ocean for the period of 1979-2014, by using climate networks of skin temperature and humidity (reanalysis data). Annual networks are constructed by creating links when the Pearson correlation coefficient between two nodes is greater than a specific value. The distance distribution Pd(k), that indicates the fraction of pairs of nodes at distance k, is computed to characterize the dynamics of the network by using Information Theory quantifiers. We found a clear change in the Indian Ocean dynamics and an increment in the network's similarities quantified by the Jensen-Shannon divergence in the late 1990s. We speculate that

    Oceanic heat transport variations, carried by the northward flowing Atlantic Water, strongly influence Arctic sea-ice distribution, ocean-atmosphere exchanges, and pan-Arctic temperatures. Paleoceanographic reconstructions from marine sediments near Fram Strait have documented a dramatic increase in Atlantic Water temperatures over the 20th century, unprecedented in the last millennium. Here we present results from Earth system model simulations over the last millennium that reproduce and explain reconstructed integrated quantities such as pan-Arctic temperature evolution during the pre-industrial millennium as well as the exceptional Atlantic Water warming in Fram Strait in the 20th century. The associated increase in ocean heat transfer to the Arctic can be traced back to changes in the ocean circulation in the sub-polar North Atlantic. An interplay between a weakening overturning circulation and a strengthening sub-polar gyre as a consequence of 20th century global warming is identified as driving mechanism for the pronounced warming along the Atlantic Water path toward the Arctic. Simulations covering the late Holocene provide a reference frame that allows us to conclude that the changes during the last century are unprecedented in the last 1150 years and that they cannot be explained by internal variability or natural forcing alone.

    Abrupt climate changes and fluctuations over short time scales are superimposed on long-term climate changes. Understanding rapid climate fluctuations at the decadal time scale over the past millennium will enhance our understanding of patterns of climate variability and aid in forecasting climate changes in the future. In this study, climate changes on the southeastern Tibetan Plateau over the past millennium were determined from a 4.82-m-long sediment core from Basomtso Lake. At the centennial time scale, the Medieval Climate Anomaly (MCA), Little Ice Age (LIA) and Current Warm Period (CWP) are distinct in the Basomtso region. Rapid climate fluctuations inferred from five episodes with higher sediment input and likely warmer conditions, as well as seven episodes with lower sediment input and likely colder conditions, were well preserved in our record. These episodes with higher and lower sediment input are characterized by abrupt climate changes and short time durations. Spectral analysis indicates that the climate variations at the centennial scale on the southeastern Tibetan Plateau are influenced by solar activity during the past millennium. PMID:27091591
