    The success of a rabies control strategy depends on the commitment and collaboration of dog owners. In this study the theory of planned behaviour (TPB) was used to identify the factors, which are associated with the intention of dog owners to participate in rabies control measures in the Manggarai and Sikka regencies of Flores Island, Indonesia. Questionnaires were administered to 450 dog owners from 44 randomly selected villages in the two regencies. Ninety-six percent of the dog owners intended to participate in a free-of-charge vaccination campaign. The intention decreased to 24% when dog owners were asked to pay a vaccination fee equal to the market price of the vaccine (Rp 18.000 per dose=US$2). Approximately 81% of the dog owners intended to keep their dogs inside their house or to leash them day and night during a period of at least three months in case of an incidence of rabies in the dog population within their village. Only 40% intended to cull their dogs in case of a rabies incident within their village. Using multivariable logistic regression analysis, the attitude item 'vaccinating dogs reduces rabies cases in humans', and the perceived behavioural control items 'availability of time' and 'ability to confine dogs' were shown to be significantly associated with the intention to participate in a free-of-charge vaccination campaign. The attitude item 'culling dogs reduces rabies cases in humans' was significantly associated with the intention to participate in a culling measure. The attitude item 'leashing of dogs reduces human rabies cases' and perceived behavioural controls 'availability of time' and 'money to buy a leash' were associated with the intention to leash dogs during a rabies outbreak. As the attitude variables were often significantly associated with intention to participate in a rabies control measure, an educational rabies campaign focusing on the benefit of rabies control measures is expected to increase the intention of dog owners to

  7. A Robust Load Shedding Strategy for Microgrid Islanding Transition

    A microgrid is a group of interconnected loads and distributed energy resources. It can operate in either gridconnected mode to exchange energy with the main grid or run autonomously as an island in emergency mode. However, the transition of microgrid from grid-connected mode to islanded mode is usually associated with excessive load (or generation), which should be shed (or spilled). Under this condition, this paper proposes an robust load shedding strategy for microgrid islanding transition, which takes into account the uncertainties of renewable generation in the microgrid and guarantees the balance between load and generation after islanding. A robust optimization model is formulated to minimize the total operation cost, including fuel cost and penalty for load shedding. The proposed robust load shedding strategy works as a backup plan and updates at a prescribed interval. It assures a feasible operating point after islanding given the uncertainty of renewable generation. The proposed algorithm is demonstrated on a simulated microgrid consisting of a wind turbine, a PV panel, a battery, two distributed generators (DGs), a critical load and a interruptible load. Numerical simulation results validate the proposed algorithm.

  8. Epidemiological transition in Easter Island (1914-1996).

    2000-05-01

    This study describes the mortality patterns during the present century (1914-1996) and investigates the epidemiological transition in a single community, Easter Island (Rapanui), the geographically most isolated inhabited island. Mortality patterns were reconstructed from civil records and included deaths of all island residents. The mean annual number of deaths is 9.3. A steady decline in the mortality rate linked to rapid modernization is the most relevant general trait. Although a small mortality crisis was detected in 9 years of the period studied, there was no significant seasonality in the deaths, possibly due to little climatic variation. The most serious sanitary problem was leprosy, endemic on the island from the end of the 19(th) century. Sanitary improvements, on one hand, and the effective breakdown of isolation, on the other, brought about the eradication of leprosy and the beginning of an epidemiological transition. In the latter years of the study, there was an increasing prevalence of degenerative diseases, connected, in part, with changes in the age structure of the population caused by the decline of mortality. A correspondence analysis shows the relationships between causes of death and age, and makes clear the different incidence of disease by age. The infant mortality rates were lower than in the Chilean population. Am. J. Hum. Biol. 12:371-381, 2000. Copyright 2000 Wiley-Liss, Inc.

    First generation students transitioning to college experience specific challenges that impact on their engagement in physical activity. Furthermore, this population experiences a context disruption that provides a unique opportunity to examine whether intention and habit predict physical activity. The aim of the current research was to determine the efficacy of the theory of planned behavior in the prediction of intention and behavior within this population, and to determine whether habit contributes to the prediction of physical activity. In this observational study, a convenience sample of first generation college students (N = 101) completed measures of theory of planned behavior variables and habit strength at Time 1, and one week later reported physical activity. The theory of planned behavior was partially supported in this context, as intention was the only significant predictor of behavior. Habit strength accounted for additional variance in physical activity but did not moderate the relationship between intention and behavior. The hypothesized model accounted for 46.9% of the variance in physical activity, and intention (β = .455) and habit (β = .364) were significant predictors. Intention and habit exert independent effects on physical activity within this population, and are both suitable targets for intervention.

    A relatively under-researched question is whether there is a possibility of influencing environmentally aware tourists regarding ecotourism at destinations that continue to develop under a pattern of mass `seaside' tourism. Our objective was to assess the pro-environmental intentions of visitors at two small Greek islands, which are within a Natura 2000 site, specifically Paxoi and Antipaxoi. Intentions involved willingness to receive information about the protected area, willingness to accept pro-environmental limitations on recreational experience, and willingness-to-pay a conditional environmental conservation value added tax. In addition, we aimed to identify determinants of visitor pro-environmental intentions among visitor and visit characteristics, visitor satisfaction, and self-reported environmental knowledge, as well as anticipated outcomes of tourism development and suggestions for protected area management. We randomly collected 324 usable questionnaires during the summer season; 242 (74.69 %) by Greek visitors and 82 (25.31 %) by foreign visitors. Visitor satisfaction was quite high; however, visitors reported low levels of environmental knowledge. Our findings showed that the unique characteristics of the destination were not salient among visitors and that there is a lack of effective outreach campaigns, interpretation, and on-site environmental education programs. However, our study revealed high levels of visitor pro-environmental intentions that might support the promotion of ecotourism on the two islands. We provide recommendations based on determinants of visitor pro-environmental intentions, which might assist towards advancing visitor participation in environmental education projects, environmentally responsible behavior among visitors, and financial contribution to environmental conservation by visitors.

    2016-01-01

    The so-called island model of protein structural transition holds that hydrophobic interactions are the key to both the folding and function of proteins. Herein, the genesis and statistical mechanical basis of the island model of transitions are reviewed, by presenting the results of simulations of such transitions. Elucidating the physicochemical mechanism of protein structural formation is the foundation for understanding the hierarchical structure of life at the microscopic level. Based on the results obtained to date using the island model, remaining problems and future work in the field of protein structures are discussed, referencing Professor Saitô’s views on the hierarchic structure of science.

    Graphical abstract: - Highlights: • All Fe{sub 13}Ge{sub 8} islands will grow into Ge(0 0 1) substrate at temperatures from 350 to 675 °C. • Shape transition occurred from kinetically constrained to equilibrium regime. • All endotaxial islands can be clarified into two types. • The mechanisms of endotaxial growth and shape transition have been rationalized. - Abstract: A comprehensive study of Fe grown on Ge(0 0 1) substrates has been conducted at elevated temperatures, ranging from 350 to 675 °C. All iron germinide islands, with the same Fe{sub 13}Ge{sub 8} phase, grow into the Ge substrate with the same epitaxial relationship. Shape transition occurs from small square islands (low temperatures), to elongated orthogonal islands or orthogonal nanowires (intermediate temperatures), and then finally to large square orthogonal islands (high temperatures). According to both transmission electron microscopy (TEM) and atomic force microscopy (AFM) investigations, all islands can be defined as either type-I or type-II. Type-I islands usually form at kinetically constrained growth regimes, like truncated pyramids. Type-II islands usually appear at equilibrium growth regimes forming a dome-like shape. Based on a simple semi-quantitative model, type-II islands have a lower total energy per volume than type-I, which is considered as the dominant mechanism for this type of shape transition. Moreover, this study not only elucidates details of endotaxial growth in the Fe–Ge system, but also suggests the possibility of controlled fabrication of temperature-dependent nanostructures, especially in materials with dissimilar crystal structures.

    The inertial sliding of physisorbed submonolayer islands on crystal surfaces contains unexpected information on the exceptionally smooth sliding state associated with incommensurate superlubricity and on the mechanisms of its disappearance. Here, in a joint quartz crystal microbalance and molecular dynamics simulation case study of Xe on Cu(111), we show how superlubricity emerges in the large size limit of naturally incommensurate Xe islands. As coverage approaches a full monolayer, theory also predicts an abrupt adhesion-driven two-dimensional density compression on the order of several per cent, implying a hysteretic jump from superlubric free islands to a pressurized commensurate immobile monolayer. This scenario is fully supported by the quartz crystal microbalance data, which show remarkably large slip times with increasing submonolayer coverage, signalling superlubricity, followed by a dramatic drop to zero for the dense commensurate monolayer. Careful analysis of this variety of island sliding phenomena will be essential in future applications of friction at crystal/adsorbate interfaces.

  4. Dynamic effect of overhangs and islands at the depinning transition in two-dimensional magnets.

    2010-09-01

    With the Monte Carlo methods, we systematically investigate the short-time dynamics of domain-wall motion in the two-dimensional random-field Ising model with a driving field (DRFIM). We accurately determine the depinning transition field and critical exponents. Through two different definitions of the domain interface, we examine the dynamics of overhangs and islands. At the depinning transition, the dynamic effect of overhangs and islands reaches maximum. We argue that this should be an important mechanism leading the DRFIM model to a different universality class from the Edwards-Wilkinson equation with quenched disorder.

    2016-03-01

    The turnover rate of new graduate nurses in Korea is twice that of all Korean nurses; job/work environment satisfaction is a known risk factor. The authors examined these factors in new graduate nurses at various transition periods. A cross-sectional survey was conducted using stratified sampling from nine regions of Korea, and 443 new graduate nurses were enrolled. Job/work environment satisfaction and turnover intention were measured. Stepwise multiple regression analysis identified the factors affecting turnover intention. The factors differed through the transition periods. At 0 to 6 months, the factors were work schedule, desired hospital, orientation duration, becoming part of a team, professional development, and practical support; at 7 to 12 months, the factors were work schedule and desired hospital; and at 13 to 18 months, the factor was professional development, which accounted for 31%, 22.9%, and 12.6%, respectively, of the reasons for turnover intention. Reducing turnover intention requires consideration of the influential factors at each transition period. Copyright 2016, SLACK Incorporated.

    The isolated population of the Island of Susak was thoroughly studied by a multidisciplinary team of the Croatian Academy of Sciences and Arts in early 1950's. Recently, a team of scientists revisited the island. This paper describes the main characteristics of the transition process during which a massive exodus occurred with 90% of the island's population migrating to New Jersey, USA. We summarise the differences in lifestyle, economy, social structure and sense of identity between the historic (1950's) and contemporary (2001) Susak population. We applied contemporary methods (analysis of microsatellite DNA polymorphisms) to investigate local myths about extreme levels of inbreeding and genetic homogeneity among the Susak islanders. Analysis of short-tandem-repeat (STR) loci showed that Susak displayed characteristics of a small homogeneous breeding isolate. The average heterozygosity was found to be low compared to outbred populations. The signature of a recent severe bottleneck could be detected. Analysis of 8 markers located on Xq13-21 in 71 individuals suggested extensive level of linkage disequilibrium (LD). A migrant study was designed to investigate the effects of large environmental changes (Susak vs. USA) and inbreeding (Susak vs. Croatian general population) on some biologically important quantitative traits, such as blood pressure and serum lipids. The results confirmed the positive correlation between inbreeding level and blood pressure that has been reported in the literature on several occasions. The last remnants of this traditional island community will soon be lost forever.

  9. Association of Transition Readiness to Intentional Self-Regulation and Hopeful Future Expectations in Youth With Illness.

    Little is known about how transition readiness relates to other developmental skills of adolescence in youth with chronic illness. Better understanding of how transition readiness relates to these other developmental skills could lead to a broader array of tools to improve transition readiness. Intentional self-regulation (ISR) and hopeful future expectations (HFE) are 2 developmental skills of adolescence that improve with participation in developmental programming and thus are modifiable. We explored associations between transition readiness, as measured by the Transition Readiness Assessment Questionnaire 29 (TRAQ-29) and ISR and HFE in youth with chronic illness recruited from a variety of subspecialty clinics from a major southeast medical center. A total of 71 adolescents with chronic illness were included in the analysis. The TRAQ-29 Self-Advocacy domain showed positive associations to both ISR (P = .03) and HFE (P = .009). In addition, the TRAQ-29 overall had positive associations to HFE (P = .04). The significant associations between TRAQ-29 Self-Advocacy domain scores and ISR and HFE suggest that transition readiness is developing within the context of other developmental areas in adolescence. More work is needed to see if the programming that improves these other developmental skills might also improve transition readiness. Copyright © 2016 Academic Pediatric Association.

    In/Si(111) has been studied with spot profile analysis low-energy electron diffraction, scanning tunneling microscope, and first-principles total energy calculations to identify its growth morphology at low temperatures. Of the different substrate interfaces used, only In growth on Si(111)- Pb-{alpha}-{radical}3 x {radical}3 has resulted in uniform height fcc (111) four-layer islands. A transition to the bulk bct (101) oriented islands is favored at higher temperatures T>250K and/or larger coverages {Theta} > 5ML. These results suggest two stabilizing effects for the preferred morphologies, i.e., quantum size effects and orientation dependent surface and interface energies. These stabilizing effects are supported from first-principles calculations.

    Introduction Tobacco smoking is a very significant behavioural risk factor for the health of Australian Aboriginal and Torres Strait Islanders, and is embedded as a social norm. With a focus on women of childbearing age, and men of similar age, this project aims to determine how Aboriginal and Torres Strait Islander smokers assess smoking risks and how these assessments contribute to their intentions to quit. The findings from this pragmatic study should contribute to developing culturally targeted interventions. Methods and analysis A cross-sectional study using quantitative and qualitative data. A total of 120 Aboriginal and Torres Strait Islander community members aged 18–45 years will be recruited at community events and through an Aboriginal Community Controlled Health Service (ACCHS). Participants will be interviewed using a tablet computer or paper survey. The survey instrument uses modified risk behaviour scales, that is, the Risk Behaviour Diagnosis (RBD) scale and the Smoking Risk Assessment Target (SRAT) (adapted from the Risk Acceptance Ladder) to determine whether attitudes of Aboriginal and Torres Strait Islander smokers to health risk messages are predictors of intentions to quit smoking. The questionnaire will be assessed for face and content validity with a panel of Indigenous community members. The internal consistency of the RBD subscales and their patterns of correlation will be explored. Multivariate analyses will examine predictors of intentions to quit. This will include demographics such as age, gender, nicotine dependence, household smoking rules and perceived threat from smoking and efficacy for quitting. The two risk-assessment scales will be examined to see whether participant responses are correlated. Ethics and dissemination The Aboriginal Health & Medical Research Council Ethics Committee and university ethics committees approved the study. The results will be published in a peer-reviewed journal and a community report will be

    The report contains a description of the elements and recommendations of a transportation study of the islands of St. Thomas, St. Croix, and St. John in the U.S. Virgin Island archipelago. St. Thomas transit recommendations included the purchase of new buses, the construction of new maintenance facilities, a substantial increase in service levels, and an open competition for management and operation of the service. For St. Croix, a subsidized taxivan service was recommended on a trial basis on three routes; highway recommendations included an increase in roadway capacity along the Charlotte Amalie waterfront and reconstruction of critical intersections. Traffic engineering improvements, and the implementation of a paid on-street parking program were recommended for St. Thomas. Reconstruction of major intersections, several turning movement enhancements, construction of the long-proposed Christiansted bypass, the expression of off-street parking lots in Christiansted, and on-street parking management changes were recommended for St. Croix. The study endorsed current Department of Public Works plans to rehabilitate sections of major roadways on St. John. Of an institutional nature, it was recommended that a new governmental instrumentality be created to oversee mass transportation (including ferries), parking, and taxi services. Several possible sources of added revenue were discussed as potential means of providing the funding for the needed improvements.

  15. Fertility intentions and risk management: exploring the fertility decline in Eastern Europe during transition.

    PubMed

    Rodin, Johnny

    2011-03-01

    Between 1985 and 1995, fertility in Eastern Europe declined from 2.2 children per woman to merely 1.5 on region-average. Previous research has emphasized mainly the economic turmoil during transition or the influx of new ideas regarding fertility and family relations. This article suggests that applying a risk management perspective on fertility patterns may put additional light on the reasons behind the fertility decline in post-communist Europe. The complexity of modern social systems has made people increasingly dependent on the state for risk evaluation and risk management. The article formulates the hypothesis that transition itself disrupted the mental models that helped people to navigate among the risks associated to having and raising children. Left to their own devices, women in Eastern Europe became more inclined to postpone childbirth or discard this option altogether.

    Plasma-assisted molecular-beam epitaxial growth of InN on GaN(0001) is investigated. Both layer-by-layer and Stranski-Krastanov (SK) growth modes are observed under different growth windows. Strain relaxation is studied by real-time recording of the in-plane lattice spacing evolutions on RHEED pattern, which suggest a gradual relaxation of the strain in InN film commenced during the first bilayer (BL) deposition and almost completed after 2-4 BLs. For SK growth, 3D islanding initiates after the strain has mostly been relieved, presumably by dislocations. Based on statistical analysis, the shape transitions of 3D islands are firstly observed in the III-nitrides system. The InN islands transform gradually from pyramids to platelets with increasing of In flux. Under In-rich growth condition, the reverse trend of island shape evolution dependence on volume size, compared with Equilibrium Crystal Shape (ECS) theory, is induced by the Indium self-surfactant effects, in which Indium adlayer on the top surface of InN islands will depress the thermodynamic driving force for the vertical growth of 3D islands. Lateral growth of 3D islands is not only the result of kinetic process but also favored by thermodynamics while Indium self-surfactant exist.

  17. Neotectonics and basin development at a continental/island arc transition in the Western Alaska Peninsula shelf

    Newcomb, K.R.

    A transition in shelf structure occurs between the eastern Alaska Peninsula and the Aleutians. In the east, compressive structures striking parallel to the margin characterize the outer shelf off of Kodiak, Chirikov, and Semidi Islands. Further to the west, multichannel seismic (MSC) data exhibit a systematic transition in style of deformation and orientation of recently active structures in the shelf region of the Shumagin and Sanak Islands. In this area, deformation near the trench slope break is manifested by drapelike folds and normal faults striking parallel to the margin. In contrast, further west between the Shumagin and Sanak Island, MCS profiles for the shelf region reveal basement-involved extensional structures transverse to the margin that have controlled the development of the Sanak and East Sanak Basis. These fault bounded basins have hanging wall sequences with syndepositional rotational displacements over normal faults, indicating a protracted history of extensional faulting and basin subsidence. Present displacement is indicated by the effects of many of the faults upon the uppermost basin and shelf strata, which in some cases offset the sea floor. The aforementioned systematic change in shelf structure of the Alaska Peninsula is coincident with an arcward shift in bathymetric contours of the trench and slope. This transition zone, from margin-parallel compressive structures in the east, to margin-transverse extensional structures in the west, coincides with the continental to island arc transition in the North American plate that reflects the ancient Beringian margin of western Alaska.

    Abstract Background This paper describes an occurence dataset, also including numerical abundance and biomass data, pertaining to the macrobenthic molluscan assemblages from a marine - lagoonal environmental transition. The study system was the soft-substrate benthoscape of the area of the Kalloni solar saltworks (Lesvos Island, Greece). Specifically, the study area extended from the infralittoral zone of the inner Kalloni Gulf (marine habitat) to the bottoms of the first two evaporation ponds of the Kalloni solar saltworks (lagoonal habitat). Bottom sediment samples (3 replicates) were collected with a Van Veen grab sampler (0.1 m2) at four sampling sites, along a 1.5 km long line transect that spanned the marine - lagoonal environmental transition. A total of four surveys were carried out seasonally in 2004.  A total of 39,345 molluscan individuals were sorted out of the sediment samples and were identified to 71 species, belonging to the Gastropoda (36), Bivalvia (34) and Scaphopoda (1) classes. Numerical abundance and wet biomass (with shells) data are included in the dataset. New information The dataset described in the present paper partially fills a significant gap in the scientific literature: Because ecological research of coastal lagoons has seldom explicitly considered the marine - lagoonal habitats interface, there are no openly accessible datasets pertaining to the particular structural component of the transitional waters benthoscapes of the Mediterranean Sea. Such datasets could prove valuable in the research of the structure and functioning of transitional waters benthoscapes. The present dataset is available as a supplementary file (Suppl. material 1) and can also be accessed at http://ipt.medobis.eu/resource?r=kalloni_saltworks_phd. PMID:27932914

    The authors report the behavior of the earth's magnetic field for a transition recorded in lavas at the volcanic island of Huahine in French Polynesia, south-central Pacific Ocean. Detailed intermediate fields are observed that record an apparent N-N excursion. The available K-Ar ages indicate that most volcanic rocks of the southern part of Huahine erupted at a time close to the Kaena subchron. Gaps in the paleomagnetic sampling or a hiatus in the volcanic activity during the Kaena event may have led to the partial record of a complete polarity transition, missing the fully reversed state. Nevertheless, numerous flows have recorded intermediate fields that somewhat constrain reversal models. The low intensities of magnetization associated with the intermediate directions suggest that the transitional field has mainly low intensities. The beginning of the transition shows inclination steepening, consistent with a zonal model of geomagnetic field reversal based on an axial quadrupole. Large deviations from a north-south planar distribution of the intermediate directions show that non axisymmetrical nondipolar fields are important in the middle of the transition.

    Understanding people's social lived experiences of chronic illness is fundamental to improving health service delivery and health outcomes, particularly in relation to self-management activity. In explorations of social lived experiences this paper uncovers the ways in which Aboriginal and Torres Strait Islander people with chronic illness experience informal unsolicited support from peers and family members. Nineteen Aboriginal and Torres Islander participants were interviewed in the Serious and Continuing Illness Policy and Practice Study (SCIPPS). Participants were people with Type 2 diabetes (N = 17), chronic obstructive pulmonary disease (N = 3) and/or chronic heart failure (N = 11) and family carers (N = 3). Participants were asked to describe their experience of having or caring for someone with chronic illness. Content and thematic analysis of in-depth semi-structured interviews was undertaken, assisted by QSR Nvivo8 software. Participants reported receiving several forms of unsolicited support, including encouragement, practical suggestions for managing, nagging, growling, and surveillance. Additionally, participants had engaged in 'yarning', creating a 'yarn' space, the function of which was distinguished as another important form of unsolicited support. The implications of recognising these various support forms are discussed in relation to responses to unsolicited support as well as the needs of family carers in providing effective informal support. Certain locations of responsibility are anxiety producing. Family carers must be supported in appropriate education so that they can provide both solicited and unsolicited support in effective ways. Such educational support would have the added benefit of helping to reduce carer anxieties about caring roles and responsibilities. Mainstream health services would benefit from fostering environments that encourage informal interactions that facilitate learning and support in a relaxed atmosphere.

    The stability of a strained cuboidal island deposited on a substrate has been numerically investigated by means of finite element simulations in the case where the structure is submitted to misfit strain resulting from the lattice mismatch between the island and the substrate. In the hypothesis where the surface energy is isotropic, it is found that, depending on the island volume, the formation of a truncated or inverted truncated pyramid can be favored by the misfit strain with respect to the cuboidal shape. A shape diagram is finally provided as a function of the misfit strain and island volume.

    To examine the independent and combined effects of Theory of Planned Behavior (TPB) variables and trait self-control (TSC) in the prediction of fruit and vegetable consumption (FVC) among first-year university students. Seventy-six first-year undergraduate university students. In their first week of class (September 2011), participants completed baseline measures of TSC, attitudes, subjective norms, perceived behavioral control, and intentions about their FVC. One week later, students completed a 7-day food recall, from which daily FVC was calculated. Baseline attitudes and perceived behavioral control predicted intentions (adjR(2) = .58). Intentions and TSC predicted FVC (adjR(2) = .24). The TPB may be a useful framework on which to base a FVC intervention for first-year undergraduate students; however, focusing solely on increasing positive intentions to consume FVC will not necessarily translate into FVC behavior, as other personal- and environmental-level variables may play a role.

Combining low energy electron microscopy, atomic force microscopy, kinetic Monte Carlo simulations, and an analytic model based on reaction and diffusion at the solid interface, we show that the shape of the nanopits depend on the ratio R/x{sub s} with R the Si island radius and x{sub s} the oxygen diffusion-length at the Si/SiO{sub 2} interface. For small R/x{sub s}, nanopits exhibit a single-well V-shape, while a double-well W-shape is found for larger R/x{sub s}. The analysis of the transition reveals that x{sub s}∼60 nm at T≈1000 °C.

    A coupled paleomagnetic/dating investigation has been conducted on a sequence of 25 successive lava flows, emplaced during the upper transition of the Jaramillo subchron in Tenerife, Canary Islands. This sequence is located along the western wall of the Güímar collapse scar, in the south central part of the island. Nine flows distributed throughout this sequence were dated using unspiked K/Ar and 40Ar/39Ar methods. They bracket the section between 1009±22 ka and 971±21 ka (2σ). A first group of 8 flows at the bottom of the sequence is characterized by normal polarity with paleointensity values of the order of present-day field intensity in the Canary Islands. The virtual geomagnetic poles (VGP) of these 8 flows describe a short loop at high latitudes. Seven overlying flows are transitional in directions and dated between 991±14 ka and 1002±11 ka consistently with published ages of the upper Jaramillo reversal. This second group of flows is characterized by low paleointensity values (around 8-12 μT) that are less than 30% of the present dipole value in Tenerife. The VGPs of the first two transitional flows lie over northeastern Pacific whereas the five following transitional flows have all negative inclinations and their VGPs lie initially over East Antarctica, then describe a northward loop almost reaching New Zealand. The final group of ten flows yield intensities varying between 20 and 35 μT and VGPs close to the southern pole with two of them describing a small amplitude second loop to southeastern Pacific. Assuming a constant extrusion rate as a very first approximation, the distribution of the obtained ages suggests a duration of 7.6±5.6 ka for the transitional interval. The obtained transitional positions of VGPs are consistent with the path reported for the same reversal from North Atlantic sediments but are different from the only other volcanic record from Tahiti. The intensity low characterizing the transitional interval remains the best tie

    We present results from a study of a partial magnetic polarity transition record from a 9.7 Ma 40Ar/39Ar dated volcanic section on the island of Gomera (Canary Islands, Spain). The record provides results that bear on the debate over whether long-term persistent features of field behaviour exist during transitions. The sampled section, containing more than 20 flows, begins after the onset of the transition. The nine lowermost flows in the section, which are all transitional, yield virtually identical directions and similar low paleointensities. Following the recovery of virtual geomagnetic pole positions (VGPs) to near the spin axis, paleointensities progress to very high values. Transitional directions lay due west, reflecting the presence of a non-zonal intermediate field. VGPs for these flows cluster in the west Atlantic, which according to Hoffman would correspond to a zone of fastest P-wave propagation in the lower mantle and to a radial flux centre of the present-day non-dipole field. Hoffman had noted a similar occurrence at two other locations. He found that in a select set of volcanic records VGPs tended to group over two areas (Australia and South America), which also corresponded to fast P-wave and non-dipole field anomalies. Given the discontinuous and irregular character typical of volcanic sequences, it is natural to question whether these clusters are merely artefacts of episodic volcanism or actually reflect standstills of the reversing field. We address this question for our record by comparing chemical and magnetomineralogic characteristics of the flows. We find that all of the transitional flows have very similar chemical and rock magnetic properties. Furthermore, these flows differ significantly from the overlying reverse flows, which give distinctly different values and much greater flow-to-flow variation. From this we conclude that the packet of transitional flows was derived from the same source and had erupted over a relatively short period

    This paper reports an experimental observation of spontaneous transition of the core radial electric field to a large positive value (E(r) similar to 5 kV m(-1)), with a strong electric-field shear (similar to 700 kV m(-2)) in a low temperature (T(e) similar to 10 eV) radio frequency generated argon plasma in the H-1NF heliac stellarator. The transition, which seems to be driven by a spontaneous excitation of m = 2 magnetic islands near the core, is associated with a localized increase in the plasma density and excitation of coherent low frequency (similar to 3 kHz) oscillations possibly due to unstable E(r) shear driven modes. Evidence suggests development of the core electron-root scenario, which previously has been observed only at high temperature electron cyclotron heated plasmas.

  13. A Re-Interpretation of the 'Two-child Norm' in Post-Transitional Demographic Systems: Fertility Intentions in Taiwan.

    PubMed

    Basten, Stuart; Verropoulou, Georgia

    2015-01-01

    Taiwan currently has one of the lowest fertility rates in the world, leading to projections of rapid population ageing and decline. In common with other territories in Pacific Asia, policies designed to support childbearing have recently been introduced. Some optimism for the future success of these policies has been drawn from the fact that the 'ideal' number of children stated in Taiwanese surveys is over two. In this way, Taiwan appears to fit the 'two-child norm' model identified for Europe and North America. Furthermore, this feature has led commentators to state that Taiwan is not in a 'low fertility trap'-where positive feedback mechanisms emanating from the normalisation of small families, slow economic growth and ageing/declining population mean attempts to increase fertility become ever less likely to succeed. Using a recent national representative survey, and arguing that 'intentions' are a more reliable guide to understanding the circumstances of family formation, this paper explores fertility intentions in Taiwan with a special focus on women at parity one and parity two. This will form the first full-length examination of fertility intentions in Taiwan published in English and one of the few studies of Pacific Asia that reports a micro-level analysis. We argue that using intentions should provide a better 'barometer' of attitudes towards childbearing in Taiwan, and that through micro-level analysis, we can better identify the predictors of intentions that could, in turn, provide useful clues both for projections as well as shaping policy responses. While we found some evidence for a 'two-child norm' among childless women, this could be an unrealistic ideal. This is supported by the fact that a majority of women with one child do not intend to have another.

  14. Shape transitions and island nucleation for Si/Ge molecular beam epitaxy on stripe-patterned Si (001) substrate

    2009-09-15

    Si and Ge growth on the stripe patterned Si (001) substrates is studied using scanning tunneling microscopy. During Si buffer growth, the stripe morphology rapidly evolves from multifaceted ''U'' to ''V''-shaped forms. This involves successive transitions between different low energy (11n) side facets, where n continuously decreases from n=3 to 20. Ge growth on such stripes induces the formation of a pronounced side wall ripple structure when the Ge thickness exceeds three monolayers. This ripple structure consists of alternating (105) microfacets oriented perpendicularly to the stripes. Depending of the side wall geometry, Ge nanoislands subsequently nucleate either on the side walls or at the bottom of grooves. The latter only occurs for ''V''-shaped stripes, where the side wall ripples extend all the way from the top to the bottom of the grooves, allowing efficient downward mass transport. For multifaceted ''U'' stripes, the side wall ripples are interrupted by steeper side wall segments such that mounds and subsequently, pyramids and domes grow on the side walls instead of at the bottom of the grooves. The island shapes strongly depend on their position on the pattern topography, which also affects the critical coverage for island nucleation as well as for the transition from pyramids to domes. The mechanisms for nucleation at different positions are clarified by detailed analysis and the role of kinetic as well as energetic factors identified.

    A molecular dynamics simulation case study of Xe on Cu(111) reveals unexpected information on the exceptionally smooth sliding state associated with incommensurate superlubricity which is argued to emerge in the large size limit of naturally incommensurate Xe islands. As coverage approaches a full monolayer, theory predicts an abrupt adhesion-driven two-dimensional density compression on the order of several per cent, implying a hysteretic jump from superlubric free islands to a pressurized sqrt()x sqrt()commensurate (and pinned, and therefore immobile) monolayer. These results match with recent quartz crystal microbalance data which show remarkably large slip times with increasing submonolayer coverage, signalling superlubricity, followed by a dramatic drop to zero for the dense commensurate monolayer. Careful analysis of this variety of island sliding phenomena should be essential in future applications of friction at crystal/adsorbate interfaces. Matching experimental work by M. Pierno, L.

  1. Transition of Mount Etna lavas from a mantle-plume to an island-arc magmatic source.

    2001-08-30

    Mount Etna lies near the boundary between two regions that exhibit significantly different types of volcanism. To the north, volcanism in the Aeolian island arc is thought to be related to subduction of the Ionian lithosphere. On Sicily itself, however, no chemical or seismological evidence of subduction-related volcanism exists, and so it is thought that the volcanism-including that on Mount Etna itself-stems from the upwelling of mantle material, associated with various surface tectonic processes. But the paucity of geological evidence regarding the primary composition of magma from Mount Etna means that its source characteristics remain controversial. Here we characterize the trace-element composition of a series of lavas emitted by Mount Etna over the past 500 kyr and preserved as melt inclusions inside olivine phenocrysts. We show that the compositional change in primary magmas from Mount Etna reflects a progressive transition from a predominantly mantle-plume source to one with a greater contribution from island-arc (subduction-related) basalts. We suggest that this is associated with southward migration of the Ionian slab, which is becoming juxtaposed with a mantle plume beneath Sicily. This implies that the volcanism of Mount Etna has become more calc-alkaline, and hence more explosive, during its evolution.

The June 5th/6th transit of Venus was one such event. In celebration, nine astronomy postdocs from the Chilean mainland traveled to Easter Island to lead a series of astronomy outreach activities over three days, culminating in a transit-viewing event. Our team dubbed "Equipo Hetu'u" or "Team Star" in the Rapa Nui (Easter Island native) language spent two days giving astronomy talks and doing hands-on demonstrations at the Museo Antropologico P. Sebastian Englert. In the final day-and-a-half leading up to the transit, we visited the science classes in the majority of the schools on the island, in order to spread the message about the once-in-a-lifetime transit event, highlighting how we planned on using it to measure the distance to the Sun. We estimate over 25% 1500 people) of this remote island participated in one or more of our organized activities. Our experience with this project is an excellent lesson on how to organize, lead, and fully execute a major outreach endeavor that inspires hundreds with minimal resources (save the spectacular event provided by the cosmos).

With data on two cohabiting cohorts from the NSFG 1995 and 2006–10, the current study finds that marriage rates among cohabitors have declined steeply among those with no college degree, resulting in growing educational disparities over time. Moreover, there are no differences in marital intentions by education (or race-ethnicity) among recent cohabitors. We discuss how findings of this study speak to the changes in the dynamics of social stratification system in the United States and suggest that institutional and material constraints are at least as important as ideational accounts in understanding family change and family behavior of contemporary young adults.

    While HIV rates are low for Asian/Pacific Islanders (APIs), they have been increasing, especially for API women in the USA. We conducted a cross-sectional study with 299 young API women (18-24 years old) in the Inland Empire region of Southern California to better understand their intention for HIV testing and their perceptions about HIV/AIDS. Data analyses included descriptive statistics, bivariate exploration for model building and multivariate analyses to determine variables associated with HIV-testing intentions. Results suggest that more lifetime sexual partners, greater perceived gender susceptibility, higher HIV/AIDS knowledge, sexually active, more positive attitudes about HIV testing and higher self-perceptions/experiences related to risk contribute to stronger intentions for HIV testing in young API women. Findings from this study will contribute to the limited literature on HIV/AIDS in API women and provide information that can be used for developing and implementing culturally appropriate programs that encourage HIV prevention and testing in this population.

    A detailed study of 43 lava flows comprising two stratigraphic sequences exposed along the north and south walls of Barranco de los Tilos on the island of La Palma, Canary Islands, reveals a complex, temporally segmented record of geodynamo behavior that contains no less than three distinct geomagnetic events. The Matuyama-Brunhes (M-B) reversal is recorded in five transitionally magnetized lava flows from the north (TN) section. The isochrons obtained from three of the lower four M-B lavas are defined by 14 incremental heating experiments that, together with a previous age determination, yielded a weighted mean of 798.4 ± 6.2 ka (all uncertainties ±2σ). In addition, a 780.3 ± 10.3 ka isochron was determined for the overlying transitionally magnetized flow, indicating that it was erupted during a distinctly younger portion of the transition. Near the base of the south (TS) section one finds a sequence of weakly magnetized flows associated with virtual geomagnetic pole (VGP) positions in the southwest Indian Ocean between latitudes 56°S and 65°S, suggesting instability of the geomagnetic field beyond that of typical secular variation. 40Ar/39Ar isochrons from three of these flows, defined by 11 separate incremental heating experiments, gave a weighted mean of 822.2 ± 8.7 ka. This anomalous field behavior recorded 24 ± 11 kyr prior to the M-B reversal may coincide with an event featured in several marine sediment records. Directly above two normal polarity flows (40Ar/39Ar isochrons of 751.9 ± 18.1 ka and 675.0 ± 15.7 ka) are nine transitionally magnetized lavas having magnetization directions associated with low to midlatitude VGPs spanning 23°-60°N. These flows are then capped by a single flow possessing normal polarity. Based on 12 incremental heating experiments, 40Ar/39Ar isochrons of five of these nine lavas, along with the uppermost flow, gave a weighted mean age of 580.2 ± 7.8 ka for this period of transitional to normal field behavior.

    The exceptionally large gold resource at Ladolam (>1,300 metric tons of gold), Lihir Island, resulted from the transition of an early-stage, low-grade porphyry gold system to a low-sulfidation epithermal gold event. This transition was probably triggered by rapid decompression during the partial slope failure of Luise stratovolcano and accompanied by the ingress of seawater. The original porphyry stage is indicated by remnant hydrothermal breccia clasts of strongly biotite-magnetite altered monzodiorite with disseminated pyrite ± chalcopyrite and poorly developed pyrite ± quartz stockwork veins. The breccias are overprinted by biotite-magnetite alteration and their matrix is strongly mineralized with disseminated auriferous pyrite. The breccias are cut by late-stage epithermal quartz-chalcedony-illite-adularia-pyrite veins and associated illite-adularia alteration that locally contain bonanza gold grades of up to 120 g/t. Isotope data suggest a magmatic source of sulfur in the gold-bearing fluids at Ladolam.

  7. Production of Carbon Dioxide From Sub-aerially Exposed Continental Shelves and Oceanic Islands During Glacial Periods Since the Middle Pleistocene Climatic Transition

    The EPICA Dome C ice core has yielded an 800,000-year record of atmospheric carbon dioxide composition from the Middle Pleistocene climatic transition to the present day. In this record, there is a sharp increase in carbon dioxide immediately following the glacial maxima during the glacial periods which to date remains difficult to explain. We will present evidence to show that sub-aerially exposed continental shelves and oceanic islands may be at least partly responsible for the production of the missing carbon dioxide. In exposed siliciclastic-dominated shelves and oceanic islands, acid-sulphate soil development would lead to the release of carbon dioxide. On the other hand, in exposed carbonate-dominated shelves and oceanic islands, karstification would also lead to the release of carbon dioxide. Selected cores from continental shelves and oceanic islands will be used to support this claim. Further studies on cores obtained from other continental shelves and oceanic islands would facilitate the estimation of carbon dioxide loss through comparison between Holocene marine deposits and their pre-Holocene counterparts. Additionally, information on the vegetation history of exposed shelves and oceanic islands during glacial periods may be obtainable to supplement our knowledge gap on past changes in the biological pump.

    Photophysiological variability and its influence on primary production were studied in the NW Africa-Canary Islands coastal transition zone. The region showed strong mesoscale activity, in which upwelling filaments and island eddies interacted to cause significant vertical displacements of the deep chlorophyll maximum (DCM). Oligotrophic stations both in the open ocean and within anticyclonic eddies were characterised by low values of integrated chlorophyll (33 ± 4 mg chl a m- 2) and dominance of pico- and nanophytoplankton, while stations associated with filaments and cyclonic eddies showed moderate chl a values (50 ± 17 mg m- 2). Shelf stations affected by upwelling exhibited the highest chl a (112 ± 36 mg m- 2) with microphytoplankton dominance. Photosynthetic variables in the three groups of stations showed similar depth gradients, with maximum photosynthetic rates (PmB) decreasing with depth and maximum quantum yields (ϕm) increasing with depth. However, the increase with depth of ϕm was not so evident in shelf waters where nutrients were not depleted at the surface. Primary production (PP) displayed a coast-ocean gradient similar to that of chl a, with highest values (2.5 ± 1.2 g C m- 2 d- 1) at the eutrophic shelf stations and lowest (0.36 ± 0.11 g C m- 2 d- 1) at the oligotrophic stations. Nevertheless, integrated PP at the oligotrophic stations was not related to integrated chl a concentration but was positively (r = 0.95) correlated to carbon fixation at the DCM and negatively (r = - 0.85) correlated to the depth of the DCM, suggesting that light, and not phytoplankton biomass, was the main factor controlling PP in oligotrophic environments. It is concluded that downward displacements of the DCM, either by convergence fronts or downwelling at the core of anticyclones can significantly reduce PP in the oligotrophic ocean.

    The northern coast of Ellesmere Island in the Canadian high Arctic (latitude 83N, longitude 75 W) contains a diverse range of lakes in which persistent ice plays a major role in their ecosystem structure and dynamics. Five meromictic lakes occur in this area and are the result of isostatic uplift trapping basins of seawater, subsequently overlain by low conductivity melt-water. The lakes are protected from wind-induced mixing by thick ice cover though most or all of the year. As a result they are highly stratified with strong vertical gradients in biogeochemical properties and in biological community structure. Our recent measurements indicate that this ice cover is now being lost during warm summers, and the lakes are passing across an abrupt transition in their physical regime that may ultimately have strong impacts on their chemical and biological properties. A 440 sq. km expanse of ice (Ward Hunt Ice Shelf ) extends off the coast of Ellesmere Island and acts as a dam for inflowing meltwater to the surface of a deep fiord (Disraeli Fiord). The resultant 'epishelf lake' (freshwater overlying saltwater connected the sea) contains a complex microbial food web that supports higher trophic levels including zooplankton and probably fish. The ice shelf itself is covered by numerous elongate (up to 15 km long) meltwater lakes. These unique ecosystems are currently undergoing rapid change with the break-up and loss of integrity of the ice shelf. Large sections of the Ward Hunt Ice Shelf have been lost by calving, and most of the Disraeli Fiord epishelf lake has drained away through a central fissure that developed over the period 2001-3. Pronounced habitat loss is accompanying small shifts in the northern Ellesmere temperature regime, underscoring the importance of threshold effects in the cryosphere, and the extreme sensitivity of cryo-ecosystems to climate forcing.

    Essentially, the term 'biobank' can be defined in different ways. Taking the UK Biobank's experience as the main example, the Taiwan Biobank aims to collect the DNA of a large group of people on the population base and track their health and lifestyle for at least 10 years. It is hoped that the information collected, regarding the mechanisms underlying how genes and environmental factors interact with each other to make us ill, will benefit the society in various ways, including the exploration of a new generation of treatments, support to preventive medicine discovery and also the possible benefits for the promotion of evolving public health-related industries in Taiwan. However, the involvement of large-scale population base gene data collection also triggered serious ethical, legal and social issues. In Taiwan, the challenge is even more serious than for any other biobanking experiences that have occurred previously. Among all the ethical, legal and social issues, the convergence of aboriginal people protection provided under Taiwan's Constitution imposes on the research team an obligation to create an innovative Ethical & Legal Governance Framework adaptable to the unique social background of Taiwan, including a workable public consultation/communication mechanism. In early 2005, the creation of the 'Taiwan Biobank' has been included as a part of Taiwan's strategic development in promoting the country as an island of biomedicine. In this report, the ideology, the goals and special features, government strategy, visions and, in particular, the ethical, legal and social issue planning of the Taiwan Biobank will be briefly introduced and reviewed.

  11. Causal networks or causal islands? The representation of mechanisms and the transitivity of causal judgment

    PubMed Central

    Johnson, Samuel G. B.; Ahn, Woo-kyoung

    2014-01-01

    Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we used causal transitivity—the inference given A causes B and B causes C that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory (e.g., exercising, becoming thirsty, drinking water) led to transitive causal judgments. On the other hand, chains schematized as multiple chunks (e.g., having sex, becoming pregnant, becoming nauseous) led to intransitive judgments despite strong intermediate links (Experiments 1–3). Normative accounts of causal intransitivity could not explain these intransitive judgments (Experiments 4–5). PMID:25556901

    2009-07-15

    The kinetics of the growth of Ge superdomes and their facets on Si(001) surfaces are analyzed as a function of deposited Ge thickness for different growth temperatures and at a low growth rate by in situ grazing-incidence small-angle x-ray scattering in combination with in situ grazing-incidence x-ray diffraction. At a low growth rate, intermixing is found to be enhanced and superdomes are formed already at lower coverages than previously reported. In addition, we observe that at the dome-to-superdome transition, a large amount of material is transferred into dislocated islands, either by dome coalescence or by anomalous coarsening. Once dislocated islands are formed, island coalescence is a rare event and introduction of dislocations is preferred. The superdome growth is thus stabilized by the insertion of dislocations during growth.

    Homologous ARM susceptibility (κARM) and magnetic susceptibility (κ) records from u-channel samples of five short cores (TAN0712 cores 14, 15, 17, 23, 27) record the Pleistocene - Holocene transition off the West Coast of the South Island, New Zealand. Cores were collected in water depths ranging from 880-2817 m. Cores 14, 15 and 17 are situated along the north levee of Moeraki Canyon. Cores 15 and 17 are kasten cores that record a relatively homogeneous concentration of single domain (SD) grains. Core 14 is a piston core slightly closer to the edge of Moeraki Canyon. From end of core (EOC) at 3.2 m to 0.75 m, the dominance of κ indicates coarse, multi-domain (MD) magnetic grains; however, low κ units (10-20 cms thick) occur at a mean interval of 0.71 m (n=3). Cores 23 and 27 are situated on the north-west margin of Milford Basin. Variations in magnetic mineral concentration in core 23 occur approximately every 26 cm. Fast Fourier Transform analysis confirms the 26 cm cycle, although it has relatively low spectral power. Core 27 also has a short interval of variable concentration. This variation in 'magnetisability' is inferred to result from fluctuating carbonate concentrations during the glacial period leading up to the Last Glacial Maximum (LGM). All three longer piston cores (27, 23, 14) contain a coarse MD interval ranging from 0.35-1 m in thickness, which we infer to represent influx of outwash at the termination of the LGM. Overlying this interval, all five cores display a consistent SD signal inferred to represent hemipelagic sedimentation during the Holocene. Possible geomagnetic excursions are recorded in four of the cores. An inclination transition to 34.2∘ combined with a 180∘ declination transition and NRM intensity low at 0.35-0.39 m in core 17 suggests a true geomagnetic excursion. Core 15 also has inclination shallowing and an intensity low at 0.45 m. An older excursion in core 27 at 2.54-2.69 m and in core 14 at ~2.8 m may correlate. The

    This paper examines factors influencing behavioural change among smallholder farmers towards adaptation to climate change in transitional climatic zones of Africa, specifically, Hwedza District in Zimbabwe. Data for this study were collected from 400 randomly-selected smallholder farmers, using a structured questionnaire, focus group discussions and key informant interviews. The study used an ordered logit model to examine the factors that influence smallholder farmers' behavioural intention towards adaptation to climate change. Results from the study show that the gender of the household head, access to extension services on crop and livestock production, access to climate information, membership to social groups and experiencing a drought have a positive influence on farmers' attitude towards adaptation to climate change and variability. The study concluded that although the majority of smallholder farmers perceive that the climate is changing, they continue to habour negative attitudes towards prescribed climate change adaptation techniques. This study recommends more education on climate change, as well as adaptation strategies for both agricultural extension workers and farmers. This can be complemented by disseminating timely climate information through extension officers and farmers' groups. Copyright © 2017 Elsevier Ltd. All rights reserved.

  17. Chilled margin fragmentation as a trigger for transition from Strombolian to phreatomagmatic explosive activity at Cova de Paul Crater, Santo Antao, Cape Verde Islands

    2013-07-01

    Sudden transitions from effusive or mildly explosive eruptions to violent phreatomagmatic explosive activity can occur at high-elevation vents on oceanic island volcanoes. Here, we describe near-vent deposits around the large Cova de Paul crater on Santo Antao, Cape Verde Islands, which provide insights into the transition from Strombolian magmatic to violently explosive phreatomagmatic activity during one such eruption. The Strombolian deposits change from welded spatter to bedded clinkery scoria to angular blocky scoria, and contain a distinct population of strongly banded, low-vesicularity angular sub-glassy clasts with strongly prolate vesicles. These sub-glassy clasts also form a discrete layer of larger blocks at the transition to the overlying phreatomagmatic deposits. They are compositionally identical to the Strombolian scoria and are interpreted to be fragments of flow-banded chilled margins from the walls of the eruptive conduit. The layer of large sub-glassy blocks records disintegration and expulsion of the chilled margins at the transition to phreatomagmatic activity. We interpret the sequence from spatter through clinkery scoria to blocky scoria as recording an increase in groundwater inflow into the conduit from pressurised aquifers, but at coolant input ratios below those required for explosions. The shattering of the chilled margins to produce the bed of large sub-glassy blocks appears to have allowed a much greater water flow into the conduit, leading to the phreatomagmatic explosive phase of the eruption.

  20. Timing of the Northern Prince Gustav Ice Stream retreat and the deglaciation of northern James Ross Island, Antarctic Peninsula during the last glacial-interglacial transition

    The Northern Prince Gustav Ice Stream located in Prince Gustav Channel, drained the northeastern portion of the Antarctic Peninsula Ice Sheet during the last glacial maximum. Here we present a chronology of its retreat based on in situ produced cosmogenic 10Be from erratic boulders at Cape Lachman, northern James Ross Island. Schmidt hammer testing was adopted to assess the weathering state of erratic boulders in order to better interpret excess cosmogenic 10Be from cumulative periods of pre-exposure or earlier release from the glacier. The weighted mean exposure age of five boulders based on Schmidt hammer data is 12.9 ± 1.2 ka representing the beginning of the deglaciation of lower-lying areas (< 60 m a.s.l.) of the northern James Ross Island, when Northern Prince Gustav Ice Stream split from the remaining James Ross Island ice cover. This age represents the minimum age of the transition from grounded ice stream to floating ice shelf in the middle continental shelf areas of the northern Prince Gustav Channel. The remaining ice cover located at higher elevations of northern James Ross Island retreated during the early Holocene due to gradual decay of terrestrial ice and increase of equilibrium line altitude. Schmidt hammer R-values are inversely correlated with 10Be exposure ages and could be used as a proxy for exposure history of individual granite boulders in this region and favour the hypothesis of earlier release of boulders with excessive 10Be concentrations from glacier directly at this site. These data provide evidences for an earlier deglaciation of northern James Ross Island when compared with other recently presented cosmogenic nuclide based deglaciation chronologies, but this timing coincides with rapid increase of atmospheric temperature in this marginal part of Antarctica.

  9. A Re-Interpretation of the ‘Two-child Norm’ in Post-Transitional Demographic Systems: Fertility Intentions in Taiwan

    PubMed Central

    2015-01-01

    Taiwan currently has one of the lowest fertility rates in the world, leading to projections of rapid population ageing and decline. In common with other territories in Pacific Asia, policies designed to support childbearing have recently been introduced. Some optimism for the future success of these policies has been drawn from the fact that the ‘ideal’ number of children stated in Taiwanese surveys is over two. In this way, Taiwan appears to fit the ‘two-child norm’ model identified for Europe and North America. Furthermore, this feature has led commentators to state that Taiwan is not in a ‘low fertility trap’–where positive feedback mechanisms emanating from the normalisation of small families, slow economic growth and ageing/declining population mean attempts to increase fertility become ever less likely to succeed. Using a recent national representative survey, and arguing that ‘intentions’ are a more reliable guide to understanding the circumstances of family formation, this paper explores fertility intentions in Taiwan with a special focus on women at parity one and parity two. This will form the first full-length examination of fertility intentions in Taiwan published in English and one of the few studies of Pacific Asia that reports a micro-level analysis. We argue that using intentions should provide a better ‘barometer’ of attitudes towards childbearing in Taiwan, and that through micro-level analysis, we can better identify the predictors of intentions that could, in turn, provide useful clues both for projections as well as shaping policy responses. While we found some evidence for a ‘two-child norm’ among childless women, this could be an unrealistic ideal. This is supported by the fact that a majority of women with one child do not intend to have another. PMID:26291083

    1995-01-01

    We have been investigating the implications of using abstractions based on intent rather than the aggregation and information-hiding abstractions commonly used in software en- gineering: Cognitive psychologists have shown that intent abstraction is consistent with human problem-solving processes. We believe that new types of specifications and designs based on this concept can assist in understanding and specifying requirements, capturing the most important design rationale information in an efficient and economical way, and supporting the process of identifying and analyzing required changes to minimize the introduction of errors. The goal of hierarchical abstraction is to allow both top-down and bottom-up reasoning about a complex system. In computer science, we have made much use of (1) part-whole abstractions where each level of a hierarchy represents an aggregation of the components at a lower level and of (2) information-hiding abstractions where each level contains the same conceptual information but hides some details about the concepts, that is, each level is a refinement of the information at a higher level.

    STS072-732-072 (11-20 Jan. 1996) --- Three of the nineteen Galapagos Islands are visible in this image, photographed from the Earth-orbiting Space Shuttle Endeavour. The Galapagos Islands are located 600 miles (1,000 kilometers) to the west of Ecuador. The largest of the islands, Isabela, is at center (north is toward the upper right corner). The numerous circular features on the island, highlighted by clouds, are volcanoes. The Galapagos Islands owe their existence to a hot spot, or persistent heat source in the mantle, which also is located over a rift, or place where plates are separating and new crust is being created. The rift is located between the Cocos and Nazca Plates. The dark linear features on the islands are lava flows from past eruptions. The island to the left of Isabela is Fernandina, while the island to the right is San Salvador. The Galapagos Islands were visited by the English naturalist Charles Darwin in 1835.

    Although it is widely accepted that oceanic island basalts (OIB) sample geochemically distinct mantle reservoirs including recycled oceanic crust, the composition, age, and locus of these reservoirs remain uncertain. OIB with highly radiogenic Pb isotope signatures are grouped as HIMU (high-μ, with μ = 238U/204Pb), and exhibit unique Hf-Nd isotopic characteristics, defined as ΔɛHf, deviant from a terrestrial igneous rock array that includes all other OIB types. Here we combine new Hf isotope data with previous Nd-Pb isotope measurements to assess the coupled, time-integrated Hf-Nd-Pb isotope evolution of the most extreme HIMU location (Mangaia, French Polynesia). In comparison with global MORB and other OIB types, Mangaia samples define a unique trend in coupled Hf-Nd-Pb isotope co-variations (expressed in 207Pb/206Pb vs. ΔɛHf). In a model employing subducted, dehydrated oceanic crust, mixing between present-day depleted MORB mantle (DMM) and small proportions (˜5%) of a HIMU mantle endmember can re-produce the Hf-Nd-Pb isotope systematics of global HIMU basalts (sensu stricto; i.e., without EM-1/EM-2/FOZO components). An age range of 3.5 to <2 Ga is required for HIMU endmember(s) that mix with DMM to account for the observed present-day HIMU isotope compositions, suggesting a range of age distributions rather than a single component in the mantle. Our data suggest that mixing of HIMU mantle endmembers and DMM occurs in the mantle transition zone by entrainment in secondary plumes that rise at the edge of the Pacific Large Low Seismic Velocity Zone (LLSVP). These create either pure HIMU (sensu stricto) or HIMU affected by other enriched mantle endmembers (sensu lato). If correct, this requires isolation of parts of the mantle transition zone for >3 Gyr and implies that OIB chemistry can be used to test geodynamic models.

    MacArthur and Wilson's theory of island biogeography predicts that island species richness should increase with island area. This prediction generally holds among large islands, but among small islands species richness often varies independently of island area, producing the so-called ‘small-island effect’ and an overall biphasic species–area relationship (SAR). Here, we develop a unified theory that explains the biphasic island SAR. Our theory's key postulate is that as island area increases, the total number of immigrants increases faster than niche diversity. A parsimonious mechanistic model approximating these processes reproduces a biphasic SAR and provides excellent fits to 100 archipelago datasets. In the light of our theory, the biphasic island SAR can be interpreted as arising from a transition from a niche-structured regime on small islands to a colonization–extinction balance regime on large islands. The first regime is characteristic of classic deterministic niche theories; the second regime is characteristic of stochastic theories including the theory of island biogeography and neutral theory. The data furthermore confirm our theory's key prediction that the transition between the two SAR regimes should occur at smaller areas, where immigration is stronger (i.e. for taxa that are better dispersers and for archipelagos that are less isolated).

    The purpose of this study is to describe the Miocene-Pliocene microfaunal development, and to discuss its palaeoenvironmental and palaeogeographical significance. The studied section (Kalamaki section) is located in the eastern part of Zakynthos Island (western Greece). Details on lithology and stratigraphy of the section are given in Dermitzakis (1978) and Nikolaou (1986). Planktonic species indicate that sediments span the interval which corresponds to MPL1 Zone (Zanclean, early Pliocene) which is in accordance with the biostratigraphic configuration of Rouchy et al. (1992) and Pierre et al. (2006). The studied interval is characterized by the Sphaeroidinellopsis Acme Zone and the presence of Globorotalia margaritae. The recognized succession of microfossil assemblages serves to interpret the evolution of some palaeoenvironmental factors (waterdepth, salinity and oxygen content), whereas the planktonic foraminiferal zonation allows an age assignment to the events. During the Late Messinian brackish conditions became dominant. The early Pliocene is characterized by a sudden return to well oxygenated, open marine, outer shelf conditions. At the basal part of the record, the high abundance of the 'shallow water component' of the benthic foraminiferal fauna indicates a well-vegetated environment with either normal marine salinity or a tendency to hyposalinity (e.g. Murray, 2006). Open marine conditions are indicated by the diversity of benthic and planktonic foraminifera. The abundance of Lenticulina spp., Cibicidoides pseudoungerianus, Planulina ariminensis, Pullenia, Gyroidina, and the virtual absence of Cibicidoides dutemplei and other typical shelf-taxa, suggest an upper bathyal waterdepth of 300-400 m (cf. Pujos, 1976; Jorissen, 1988). Partly, the abundance of Cibicidoides pseudoungerianus, Bulimina costata and Uvigerina peregrina reflect fluctuations in oxygen content of the bottom waters. However, extreme conditions were never reached during deposition. The

    The rise of cohabitation in family process among American young adults and declining rates of marriage among cohabitors are considered by some scholars as evidence for the importance of society-wide ideational shifts propelling recent changes in family. With data on two cohabiting cohorts from the NSFG 1995 and 2006-2010, the current study finds that marriage rates among cohabitors have declined steeply among those with no college degree, resulting in growing educational disparities over time. Moreover, there are no differences in marital intentions by education (or race/ethnicity) among recent cohabitors. We discuss how findings of this study speak to the changes in the dynamics of social stratification system in the United States and suggest that institutional and material constraints are at least as important as ideational accounts in understanding family change and family behavior of contemporary young adults.

    During the Atlantic Stratocumulus Transition Experiment (ASTEX) in June 1992, simultaneous measurements were made with a vertically pointing cloud sensing radar and a microwave radiometer. The radar measurements are used to estimate stratus cloud drizzle and turbulence parameters. In addition, with the microwave radiometer measurements of reflectivity, we estimated the profiles of cloud liquid water and effective radius. We used radar data for computation of vertical profiles of various drizzle parameters such as droplet concentration, modal radius, and spread. A sample of these results is shown in Figure 1. In addition, in non-drizzle clouds, with the radar and radiometer we can estimate the verticle profiles of stratus cloud parameters such as liquid water concentration and effective radius. This is accomplished by assuming a droplet distribution with droplet number concentration and width constant with height.

    The original intent of the study was to develop a first-order synopsis of island hydrology with an integrated geologic basis on a global scale. As the study progressed, the aim was broadened to provide a framework for subsequent assessments on large regional or global scales of island resources and impacts on those resources that are derived from global changes. Fundamental to the study was the development of a comprehensive framework?a wide range of parameters that describe a set of 'saltwater' islands sufficiently large to Characterize the spatial distribution of the world?s islands; Account for all major archipelagos; Account for almost all oceanically isolated islands, and Account collectively for a very large proportion of the total area of the world?s islands whereby additional islands would only marginally contribute to the representativeness and accountability of the island set. The comprehensive framework, which is referred to as the ?Primary Island Set,? is built on 122 parameters that describe 1,000 islands. To complement the investigations based on the Primary Island Set, two supplemental island sets, Set A?Other Islands (not in the Primary Island Set) and Set B?Lagoonal Atolls, are included in the study. The Primary Island Set, together with the Supplemental Island Sets A and B, provides a framework that can be used in various scientific disciplines for their island-based studies on broad regional or global scales. The study uses an informal, coherent, geophysical organization of the islands that belong to the three island sets. The organization is in the form of a global island chain, which is a particular sequential ordering of the islands referred to as the 'Alisida.' The Alisida was developed through a trial-and-error procedure by seeking to strike a balance between 'minimizing the length of the global chain' and 'maximizing the chain?s geophysical coherence.'

    An uncommon bloom occurred in the western equatorial Pacific near 170°E, during the transition between El Niño and La Niña conditions in 1998. Previous studies attributed this bloom to large-scale wind-driven upwelling and vertical mixing, but they do not explain its particular location that coincided with the presence of small coral atolls: Gilbert Islands, Republic of Kiribati. In this study combining satellite and in-situ data with a regional physical model, we assess the impact of Kiribati Islands on the different bloom phases. We show how the islands disrupted the dynamics and the nutrient fields in this region, in such a way that bloom-favorable conditions could be created [1].

    ABSTRACT OBJECTIVE To investigate the reasons for family medicine graduates’ career choices. DESIGN Qualitative study using focus groups and one-on-one interviews. SETTING University of Calgary in Alberta. PARTICIPANTS Seventeen male and female second-year family medicine residents, representing a range of ages and areas of origin, enrolled in the 2004 urban and rural south streams of the family medicine residency program at the University of Calgary. METHOD During the final month of training, 2 focus groups were conducted to determine graduating students’ career choices and the reasons for them. After focus-group data were analyzed, a questionnaire was constructed and subsequently administered to participants during face-to-face or telephone interviews. MAIN FINDINGS Most residents initially planned to do urban locums in order to gain experience. In the long term, they planned to open practices in urban areas for lifestyle and family reasons. Many residents from the rural stream had no long-term plans to establish rural practices. Most residents said they felt prepared for practice, but many indicated that an optional third year of paid training, with an emphasis on emergency medicine, obstetrics, and pediatrics, would be desirable. Reasons cited for not practising in rural areas were related to workload, lifestyle issues, family obligations, and perceived lack of medical support in the community. Only 4 female graduates and 1 male graduate intended to practise obstetrics. The main reason residents gave for this was inadequate training in obstetrics during residency. Finances were cited as a secondary reason for many choices, and might in fact be more important than at first apparent. CONCLUSION Despite its intention to recruit family medicine graduates to rural areas and to obstetrics, the University of Calgary residency training program was not successful in recruiting physicians to these areas. The program likely needs to re-examine the effectiveness of

    Derivation of highly silica-undersaturated lavas such as olivine melilitites and melilite nephelinites from the mantle has been attributed to the effects of CO2. However, experimental studies have so far failed to demonstrate equilibrium of melilititic melts with a four-phase peridotite assemblage. Instead, the liquidus mineralogy of these silica-undersaturated magmas at high-pressures appears to be dominated by cpx1. Although, experimental partial melts from natural peridotite+CO2 span a continuum from carbonatite to alkali-basalts2, ocean-island melilitites have distinctly higher TiO2, FeO*, and CaO/(CaO+MgO)3,4 than compositions derived thus far from a carbonated lherzolite source. Partial melting experiments of a nominally anhydrous, natural eclogite with a small amount of added carbonate (SLEC1; 5 wt.% bulk CO2) were performed to investigate the transition between carbonate and silicate melts with increasing temperature. Experiments were conducted in a piston cylinder at 3 GPa from 1050 to 1400 ° C. Garnet and cpx appear in all the experiments and ilmenite is observed from 1075 to ˜1200 ° C. An Fe-bearing calcio-dolomitic melt is present from the solidus (1050-1075 ° C) up to 1375 ° C. Beginning at 1275 ° C, it coexists with a silica-poor silicate melt. Textural criteria indicate only a single CO2-rich silicate melt phase at 1400 ° C, coexisting with garnet and minor cpx. The liquidus temperature is estimated to be ˜1415 ° C from the melt fraction-temperature trend. With increasing temperature, the carbonate melt becomes richer in SiO2 ( ˜2 to 5 wt.%) and Al2O3 ( ˜0.75 to 2.25 wt.%) and poorer in CaO ( ˜30 to 25 wt.% from ˜1200 to 1375 ° C). Compositions of silicate partial melts change systematically with increasing temperature, increasing in SiO2 ( ˜36 to 41 wt.%), Al2O3 ( ˜4.5 to 9.5 wt.%), MgO ( ˜9.5 to 13 wt.%), CaO ( ˜8 to 14 wt.%) and decreasing in TiO2 ( ˜14 to 2.5 wt.%), FeO ( ˜20 to 13 wt.%), Na2O ( ˜3.3 to 1.7 wt.%).

    The volcanic activity that built up the Monte dei Porri stratocone (Salina Island) was reconstructed using new stratigraphic data, which allowed seven eruption units to be distinguished. Alternating Strombolian/Vulcanian to sub-Plinian/Plinian explosive and effusive activity emplaced fall and pyroclastic density current deposits and lava flows that formed the volcanic cone. The minimum erupted bulk volumes were assessed at 100 × 106 m3 each for EU1, EU2, EU3 and EU6, while that of EU4 is ca. 200 × 106 m3. Rough estimation of EU7 volume yields values around 150 × 106 m3. The calculation of volume was not possible for the EU5 deposits. The magmas that fed the different eruption units of the Monte dei Porri succession range in composition from basalt to andesite, with the exception of dacites erupted in the initial phase of activity. SEM image analyses on coarse ash from the different pyroclastic units suggest that hydromagmatic fragmentation cannot be the cause of the large variations in explosivity observed throughout the stratigraphic succession. Based on the lithic component of pyroclastic deposits and xenolith contents of lava flows, the plumbing system that fed the different eruption units of Monte dei Porri was split into a deep magma storage level (15-20 km) and shallower magma batches (3-5 km). Our calculations indicate that the volumes of erupted material can account for magmatic triggering (injection of new magma) of eruptive units from the shallower feeding system, but they are not sufficient for suggesting magmatic initiation of the eruption units from the deeper feeding system. It is therefore assumed that the eruptions from the deep magma reservoir necessitate a favourable lithostatic stress, likely calling for a reduction of the local tectonic forces. A qualitative model explaining the eruptive style transitions among and within the different eruption units is presented, taking into account the relation between magmatic overpressure and lithostatic

    Both Brentano and Merleau-Ponty have developed an account of intentionality, which nevertheless differ profoundly in the following respect. According to Brentano, intentionality mainly is a matter of mental presentations. This marks the beginning of phenomenology's difficult relation with the nature of the intentional reference. Merleau-Ponty, on the other hand, has situated intentionality on the level of the body, a turn which has important implications for the nature of intentionality. Intentionality no longer is primarily based on having (re)presentations, but is rooted in the dynamics of the living body. To contrast those approaches enables us to make clear in what way intentionality is studied nowadays. On the one hand, intentionality is conceived of as a matter of formal-syntactical causality in cognitive science, and in particular in classical-computational theory. On the other hand, a interactivist approach offers a more Merleau-Ponty-like point of view, in which autonomy, embodiment and interaction are stressed.

  12. Conduit Wall Failure as a Trigger for Transition From Strombolian to Phreatomagmatic Explosive Activity in the Cova de Paúl Crater Eruption on Santo Antão, Cape Verde Islands

    Episodes of hazardous phreatomagmatic explosive activity, including Surtseyan activity, occur within otherwise less dangerous effusive to mildly explosive magmatic eruptions at high-elevation vents on many oceanic island volcanoes. The water driving these explosions is sourced from freshwater aquifers within the volcanic edifices. Understanding volcanic and geophysical precursors to, and mechanisms of, the (frequently abrupt) transitions to explosive activity is required as a basis for effective warning and mitigation of the resulting hazards. Here we describe near-vent deposits around the large Cova de Paúl crater on the island of Santo Antão, Cape Verde Islands, which provide some insights into a transition from mild magmatic to violently explosive phreatomagmatic activity in one such eruption. This pre-historic but well-preserved crater formed in a single eruption that produced extensive low-temperature, lithic-rich phreatomagmatic pyroclastic flows and surge deposits; these are interbedded in proximal outcrops with airfall breccia and ash beds containing varying proportions of lithic and juvenile clasts, pointing to a series of climactic explosions within an extended period of milder explosive activity of broadly Surtseyan type. Prior to the transition to phreatomagmatic activity, the eruption had been characterized by mild Strombolian activity that produced scoria and spatter deposits of broadly tephritic composition. The Strombolian deposits contain a distinct population of strongly banded, low-vesicularity angular clasts with strongly prolate vesicles and a notably glassy appearance. These became markedly larger and more abundant just below the transition to the phreatomagmatic deposits. Comparisons of these clasts with the Strombolian scoria suggest that they are fragments of flow-banded chilled margins from the walls of the eruptive conduit. Thermal shattering of these margins to produce the angular glassy clasts may record the onset of groundwater flow

    2017-09-27

    Remote, rugged and extraordinarily beautiful, Alaska’s Aleutian Islands are best known for wildlife reserves, military bases, fishing, furs and fog. The sprawling volcanic archipelago was brought into the spotlight by the Russian-supported expedition of Alexey Chirikov and Vitus Bering in 1741, and soon became controlled by the Russian-American Fur Company. In 1867 the United States purchased Alaska, including the Aleutian Islands, from Russia. By 1900 the port in Unalaska was well established as a shipping port for Alaska gold. The archipelago sweeps about 1,200 miles (1,800 km) from the tip of the Alaskan Peninsula to Attu, the most westward island. Four major island groups hold 14 large islands, about 55 smaller islands, and a large number of islets, adding up to roughly 150 islands/islets in total. This chain separates the Bering Sea (north) from the Pacific Ocean (south) and the islands are connected by the Marine Highway Ferry – at least as far as Unalaska. For the most remote islands, such as birding paradise of Attu, the western-most Aleutian Island, travel becomes trickier and relies primarily on custom charter. The Moderate Resolution Imaging Spectroradiometer (MODIS) flew over the region and captured this spectacular true-color image of the eastern Aleutian Islands on May 15, 2014. In this image, the Alaskan Peninsula protrudes from the mainland and sweeps to the southwest. The first set of islands are called the Fox Island group. Unalaska Island is part of this group and can be identified, with some imagination, as an island formed in the shape of a flying cherub, with two arms (peninsulas) outstretched towards the northeast, seemingly reaching for the round “balls” of Akutan and Akun Islands. The smallest islands in the west of the image belong to the group known as the Islands of Four Mountains. The Aleutians continue far to the west of this image. Fog surrounds the Aleutians, stretching from just off the southwestern Alaska mainland to the

The Galapagos Islands, which are part of Ecuador, sit in the Pacific Ocean about 1000 km (620 miles) west of South America. As the three craters on the largest island (Isabela Island) suggest, the archipelago was created by volcanic eruptions, which took place millions of years ago. Unlike most remote islands in the Pacific, the Galapagos have gone relatively untouched by humans over the past few millennia. As a result, many unique species have continued to thrive on the islands. Over 95 percent of the islands' reptile species and nearly three quarters of its land bird species cannot be found anywhere else in the world. Two of the more well known are the Galapagos giant tortoise and marine iguanas. The unhindered evolutionary development of the islands' species inspired Charles Darwin to begin The Origin of Species eight years after his visit there. To preserve the unique wildlife on the islands, the Ecuadorian government made the entire archipelago a national park in 1959.

  17. An intentional interpretive perspective

    2004-01-01

    To the extent that the concept of intention has been addressed within behavior analysis, descriptions of intention have been general and have not specifically included important distinctions that differentiate a behavior-analytic approach from vernacular definitions of intention. A fundamental difference between a behavior-analytic approach and most other psychological approaches is that other approaches focus on the necessity of intentions to explain behavior, whereas a behavior-analytic approach is directed at understanding the interplay between behavior and environment. Behavior-analytic interpretations include the relations between the observer's behavior and the environment. From a behavior-analytic perspective, an analysis of the observer's interpretations of an individual's behavior is inherent in the subsequent attribution of intention. The present agenda is to provide a behavior-analytic account of attributing intention that identifies the establishing conditions for speaking of intention. Also addressed is the extent to which we speak of intentions when the observed individual's behavior is contingency shaped or under instructional control. PMID:22478417

    Akpatok Island lies in Ungava Bay in northern Quebec, Canada. Accessible only by air, Akpatok Island rises out of the water as sheer cliffs that soar 500 to 800 feet (150 to 243 m) above the sea surface. The island is an important sanctuary for cliff-nesting seabirds. Numerous ice floes around the island attract walrus and whales, making Akpatok a traditional hunting ground for native Inuit people.

  20. Thickness of the oceanic crust and the mantle transition zone in the vicinity of the Tristan da Cunha hot spot estimated from ocean-bottom and ocean-island seismometer receiver functions

    According to classical plume theory, the Tristan da Cunha hotspot is thought to have played a major role in the rifting of the South Atlantic margins and the creation of the aseismic Walvis Ridge by impinging at the base of the continental lithosphere shortly before or during the breakup of the South Atlantic margins. However, Tristan da Cunha is enigmatic as it cannot be clearly identified as a hot spot but may also be classified as a more shallow type of anomaly that may actually have been caused by the opening of the South Atlantic. The equivocal character of Tristan da Cunha is largely due to a lack of geophysical and petrological data in this region. We therefore staged a multi-disciplinary geophysical study of the region by acquiring passive marine electromagnetic and seismic data, and bathymetric data within the framework of the SPP1375 South Atlantic Margin Processes and Links with onshore Evolution (SAMPLE) funded by the German Science foundation. The experiment included two ship expeditions onboard the German R/V MARIA S. MERIAN in 2012 and 2013. In our contribution we will present results on the thickness of the oceanic crust in the vicinity of the Tristan da Cunha archipelago derived from ocean-bottom seismometer data. Using the Ps receiver function method we estimate a thickness of 5 to 7 km for the oceanic crust at 17 ocean-bottom stations surrounding the islands in an area where the ocean floor has an age of approximately 10 to 30 Ma (from west to east). This indicates normal to slightly lowered magmatic activity at the mid-ocean ridge during the crust formation. There seems to be no major contribution of a mantle plume to the melting conditions at the ridge, which should cause the formation of thickened oceanic crust. The magmatic activity at the archipelago and surrounding seamounts seems to have only local effects on the crustal thickness. Furthermore, we imaged the mantle transition zone discontinuities analysing receiver functions at the

    Background: Suicide and suicidal attempt are an important cause of mortality and denotes severe morbidity among the population. Successful suicide attempt is associated with previous suicide attempts. Identifying factors in suicide attempters will help in formulating a comprehensive response to these issues. Objective: To identify the sub group who are more vulnerable and the factors associated with this group. Setting and Design: A cross sectional observational study of this sub group was carried out. Material and Methods: study was conducted on patients who were referred to the Psychiatry department for attempted suicide. They were assessed to identify those with high suicidal intent and study the factors associated with high suicidal intent. Statistics: Epiinfo by CDC was used to analyze the results. Results: High intent was associated with history of psychiatric illness, history of previous attempts and family history of suicidal attempts. Conclusions: A sub group was identified which had a high intent and possibly higher chance of repeating an attempt. PMID:28031588

    The mainstream theories and models of the physical sciences, including neuroscience, are all consistent with the principle of causality. Wholly causal explanations make sense of how things go, but are inherently value-neutral, providing no objective basis for true beliefs being better than false beliefs, nor for it being better to intend wisely than foolishly. Dennett (1987) makes a related point in calling the brain a syntactic (procedure-based) engine. He says that you cannot get to a semantic (meaning-based) engine from there. He suggests that folk psychology revolves around an intentional stance that is independent of the causal theories of the brain, and accounts for constructs such as meanings, agency, true belief, and wise desire. Dennett proposes that the intentional stance is so powerful that it can be developed into a valid intentional theory. This article expands Dennett’s model into a principle of intentionality that revolves around the construct of objective wisdom. This principle provides a structure that can account for all mental processes, and for the scientific understanding of objective value. It is suggested that science can develop a far more complete worldview with a combination of the principles of causality and intentionality than would be possible with scientific theories that are consistent with the principle of causality alone.

  11. The Embodiment of Intentionality

    NASA Astrophysics Data System (ADS)

    Jordan, J. Scott

    Historically, the concept intentionality referred to the apparent directedness of human consciousness. Given experimental psychology's turn-of-the-century shift from consciousness to behavior, intentionality is now treated as the pre-specification of motor output, while consciousness is considered a post-stimulus, attention-attenuated input phenomenon. The present contribution challenges this approach by presenting data that indicate perception to be just as intentional as action. An alternative approach to intentionality and consciousness is then proposed, which conceptualizes organisms as energy-transformation systems that emerged, phylogenetically, via the struggle for available energy. Such systems are able to sustain themselves (i.e., survive) because they are autocatalytic; their transformation states produce products that feed back into the system as fuel. In addition, such systems are embodiments; their internal transformation states constitute encapsulations (i.e., internalizations) of transformation states that used to exist outside of the organism. Given this notion of autocatalytic embodiment, the following points are argued: (1) such systems are inherently intentional (i.e., end-directed), for the only way they can remain intact (i.e., alive) is via the active, continuous offset of perturbation to the autocatalytic transformation states that sustain them, and (2) the 'feels' traditionally referred to as consciousness, derive from the embedded, embodied, end-directed 'of-ness' inherent in all autocatalytic systems.

    On December 12, 1992, at 5:30 A.M. GMT, an earthquake of magnitude Ms 7.5 struck the eastern region of Flores Island, Indonesia (Figure 1), a volcanic island located just at the transition between the Sunda and Banda Island arc systems. The local newspaper reported that 25-m high tsunamis struck the town of Maumere, causing substantial casualties and property damage. On December 16, television reports broadcast in Japan via satellite reported that 1000 people had been killed in Maumere and twothirds of the population of Babi Island had been swept away by the tsunamis.The current toll of the Flores earthquake is 2080 deaths and 2144 injuries, approximately 50% of which are attributed to the tsunamis. A tsunami survey plan was initiated within 3 days of the earthquake, and a cooperative international survey team was formed with four scientists from Indonesia, nine from Japan, three from the United States, one from the United Kingdom, and one from Korea.

    New York City (NYC) jails are the epicenter of an epidemic that overwhelmingly affects Black and Hispanic men and offer a significant opportunity for public health intervention. The NYC Department of Health and Mental Hygiene instituted population based approaches to identify the HIV-infected, initiate discharge planning at jail admission, and facilitate post-release linkages to primary care. Using a caring and supportive 'warm transitions' approach, transitional care services are integral to continuity of care. Since 2010, over three-quarters of known HIV-infected inmates admitted to jails received discharge plans; 74 % of those released were linked to primary care. The EnhanceLink initiative's new Health Liaison, a lynchpin role, facilitated 250 court-led placements in medical alternatives to incarceration. Transitional care coordination programs are critical to facilitate continuity of care for people with chronic health conditions including the HIV-infected returning home from jail and for the public health of the communities to which they return.

  16. Barrier island bistability induced by biophysical interactions

    2015-02-01

    Barrier islands represent about 10% of the world’s coastline, sustain rich ecosystems, host valuable infrastructure and protect mainland coasts from storms. Future climate-change-induced increases in the intensity and frequency of major hurricanes and accelerations in sea-level rise will have a significant impact on barrier islands--leading to increased coastal hazards and flooding--yet our understanding of island response to external drivers remains limited. Here, we find that island response is intrinsically bistable and controlled by previously unrecognized dynamics: the competing, and quantifiable, effects of storm erosion, sea-level rise, and the aeolian and biological processes that enable and drive dune recovery. When the biophysical processes driving dune recovery dominate, islands tend to be high in elevation and vulnerability to storms is minimized. Alternatively, when the effects of storm erosion dominate, islands may become trapped in a perpetual state of low elevation and maximum vulnerability to storms, even under mild storm conditions. When sea-level rise dominates, islands become unstable and face possible disintegration. This quantification of barrier island dynamics is supported by data from the Virginia Barrier Islands, USA and provides a broader context for considering island response to climate change and the likelihood of potentially abrupt transitions in island state.

The image shows the islands of Oahu, Molokai, Lanai, Maui, and Kahoolawe. The prevailing Pacific trade winds bring higher levels of rainfall to the eastern slopes of the islands, leading to a greater abundance of vegetation on the windward coasts. The small change in observation angle across the nadir camera's field-of- view causes the right-hand portion of the image to be more affected by Sun glint, making the ocean surface appear brighter. Oahu is the westernmost of the islands seen in this image. Waikiki Beach and the city of Honolulu are located on the southern shore, to the west of Diamond Head caldera. MISR is one of several Earth-observing instruments on the Terra satellite, launched in December 1999.

    How do we understand the intentions of other people? There has been a longstanding controversy over whether it is possible to understand others’ intentions by simply observing their movements. Here, we show that indeed movement kinematics can form the basis for intention detection. By combining kinematics and psychophysical methods with classification and regression tree (CART) modeling, we found that observers utilized a subset of discriminant kinematic features over the total kinematic pattern in order to detect intention from observation of simple motor acts. Intention discriminability covaried with movement kinematics on a trial-by-trial basis, and was directly related to the expression of discriminative features in the observed movements. These findings demonstrate a definable and measurable relationship between the specific features of observed movements and the ability to discriminate intention, providing quantitative evidence of the significance of movement kinematics for anticipating others’ intentional actions.

What this paper adds When new graduate nurses are satisfied with their jobs and pay and feel committed to the organization, the odds of turnover intent decrease. Increased seeking social support to cope with the transition from student to competent Registered Nurse is related to turnover intent. Older graduates (>30) are 4·5 times more likely to have turnover intent if they do not get their ward of choice. PMID:18352963

    2004-10-01

    A two-dimensional lattice-Boltzmann model (LBM) with fluid-fluid interactions was used to simulate first-order phase separation in a thin fluid film. The intermediate asymptotic time dependence of the mean island size, island number concentration, and polydispersity were determined and compared with the predictions of the distribution-kinetics model. The comparison revealed that the combined effects of growth, coalescence, and Ostwald ripening control the phase transition process in the LBM simulations. However, the overall process is dominated by coalescence, which is independent of island mass. As the phase transition advances, the mean island size increases, the number of islands decrease, and the polydispersity approaches unity, which conforms to the predictions of the distribution-kinetics model. The effects of the domain size on the intermediate asymptotic island size distribution, scaling form of the island size distribution, and the crossover to the long-term asymptotic behavior were elucidated.

    Nunn, Patrick D.; Kumar, Lalit; Eliot, Ian; McLean, Roger F.

    2016-12-01

    An earth-science-based classification of islands within the Pacific Basin resulted from the preparation of a database describing the location, area, and type of 1779 islands, where island type is determined as a function of the prevailing lithology and maximum elevation of each island, with an island defined as a discrete landmass composed of a contiguous land area ≥1 ha (0.01 km2) above mean high-water level. Reefs lacking islands and short-lived (<20 years) transient islands are not included. The principal aim of the classification is to assess the spatial diversity of the geologic and geomorphic attributes of Pacific islands. It is intended to be valid at a regional scale and based on two attributes: five types of lithology (volcanic, limestone, composite, continental, surficial) and a distinction between high and low islands. These attributes yielded eight island types: volcanic high and low islands; limestone high and low islands; composite high and low islands; reef (including all unconsolidated) islands; and continental islands. Most common are reef islands (36 %) and volcanic high islands (31 %), whereas the least common are composite low islands (1 %). Continental islands, 18 of the 1779 islands examined, are not included in maps showing the distribution of island attributes and types. Rationale for the spatial distributions of the various island attributes is drawn from the available literature and canvassed in the text. With exception of the few continental islands, the distribution of island types is broadly interpretable from the proximity of island-forming processes. It is anticipated the classification will become the basis for more focused investigation of spatial variability of the climate and ocean setting as well as the biological attributes of Pacific islands. It may also be used in spatial assessments of second-order phenomena associated with the islands, such as their vulnerability to various disasters, coastal erosion, or ocean pollution as

  10. Asymmetric shape transitions of epitaxial quantum dots

    NASA Astrophysics Data System (ADS)

    Wei, Chaozhen; Spencer, Brian J.

    2016-06-01

    We construct a two-dimensional continuum model to describe the energetics of shape transitions in fully faceted epitaxial quantum dots (strained islands) via minimization of elastic energy and surface energy at fixed volume. The elastic energy of the island is based on a third-order approximation, enabling us to consider shape transitions between pyramids, domes, multifaceted domes and asymmetric intermediate states. The energetics of the shape transitions are determined by numerically calculating the facet lengths that minimize the energy of a given island type of prescribed island volume. By comparing the energy of different island types with the same volume and analysing the energy surface as a function of the island shape parameters, we determine the bifurcation diagram of equilibrium solutions and their stability, as well as the lowest barrier transition pathway for the island shape as a function of increasing volume. The main result is that the shape transition from pyramid to dome to multifaceted dome occurs through sequential nucleation of facets and involves asymmetric metastable transition shapes. We also explicitly determine the effect of corner energy (facet edge energy) on shape transitions and interpret the results in terms of the relative stability of asymmetric island shapes as observed in experiment.

  12. Quantifying Barrier Island Recovery Following a Hurricane

    NASA Astrophysics Data System (ADS)

    Hammond, B.; Houser, C.

    2014-12-01

    Barrier islands are dynamic landscapes that are believed to minimize storm impact to mainland communities and also provide important ecological services in the coastal environment. The protection afforded by the island and the services it provides, however, depend on island resiliency in the face of accelerated sea level rise, which is in turn dependent on the rate of island recovery following storm events that may also change in both frequency and magnitude in the future. These changes in frequency may affect even large dunes and their resiliency, resulting in the island transitioning from a high to a low elevation. Previous research has shown that the condition of the foredune depends on the recovery of the nearshore and beach profile and the ability of vegetation to capture aeolian-transported sediment. An inability of the foredune to recover may result in mainland susceptibility to storm energy, inability for ecosystems to recover and thrive, and sediment budget instability. In this study, LiDAR data is used to quantify the rates of dune recovery at Fire Island, NY, the Outer Banks, NC, Santa Rosa Island, FL, and Matagorda Island, TX. Preliminary results indicate foredune recovery varies significantly both alongshore and in the cross-shore, suggesting that barrier island response and recovery to storm events cannot be considered from a strictly two-dimensional (cross-shore) perspective.

  17. Neogene to Quaternary stratigraphic evolution of the Antarctic Peninsula, Pacific Margin offshore of Adelaide Island: Transitions from a non-glacial, through glacially-influenced to a fully glacial state

    2017-09-01

    A detailed morphologic and seismic stratigraphic analysis of the continental margin offshore of Adelaide Island on the Pacific Margin of the Antarctic Peninsula (PMAP) is described based on the study of a regular network of reflection multichannel seismic profiles and swath bathymetry. We present an integrated study of the margin spanning the shelf to the continental rise, establish novel chronologic constraints and offer new interpretations on tectonic evolution and environmental changes affecting the PMAP. The stratigraphic stacking patterns record major shifts in the depositional style of the margin that outline three intervals in its evolution. The first non-glacial interval (Early Cretaceous to middle Miocene) encompasses a transition from an active to a passive margin (early Miocene). The second glacially-influenced interval (middle to late Miocene) is marked by pronounced aggradational sedimentary stacking and subsidence. Ice sheets advanced over the middle shelf of the margin at the end of this second interval, while the outer shelf experienced rare progradational events. The third, fully glaciated interval shows clear evidence of glacially dominated conditions on the margin. This interval divides into three minor stages. During the first stage (late Miocene to the beginning of the Pliocene), frequent grounded ice advances to the shelf break began, depositing an initial progradational unit. A major truncation surface marked the end of this stage, which coincided with extensive mass transport deposits at the base of the slope. During the second progradational glacial margin stage (early Pliocene to middle Pleistocene), stacking patterns record clearly prograding glacial sequences. The beginning of the third aggradational glacial margin stage (middle Pleistocene to present) corresponded to an important shift in global climate during the Mid-Pleistocene Transition. Morphosedimentary characteristics observed along the margin today began to develop during the

  19. Intention Seekers: Conspiracist Ideation and Biased Attributions of Intentionality

    2015-01-01

    Conspiracist beliefs are widespread and potentially hazardous. A growing body of research suggests that cognitive biases may play a role in endorsement of conspiracy theories. The current research examines the novel hypothesis that individuals who are biased towards inferring intentional explanations for ambiguous actions are more likely to endorse conspiracy theories, which portray events as the exclusive product of intentional agency. Study 1 replicated a previously observed relationship between conspiracist ideation and individual differences in anthropomorphisation. Studies 2 and 3 report a relationship between conspiracism and inferences of intentionality for imagined ambiguous events. Additionally, Study 3 again found conspiracist ideation to be predicted by individual differences in anthropomorphism. Contrary to expectations, however, the relationship was not mediated by the intentionality bias. The findings are discussed in terms of a domain-general intentionality bias making conspiracy theories appear particularly plausible. Alternative explanations are suggested for the association between conspiracism and anthropomorphism. PMID:25970175

    Purpose This study explores if and how adolescents’ pregnancy intentions relate to life situations and health-related behaviors prenatally and up to 2 years postpartum. Methods Adolescent girls who reported that they had “wanted a baby” (n = 75) as their reason for pregnancy were compared with those who reported that the pregnancy “just happened” (n = 79) at four separate time periods: prenatally, at 6 and 24 months postpartum, and at 18 months postpartum for teens who became pregnant again subsequent to the study pregnancy. Results Those who stated that they wanted a baby were more likely to be Hispanic, married, and out of school before becoming pregnant. They were less likely to receive welfare as their primary means of support and to have run away from home in the past than teens who stated that their pregnancy just happened. Self-reported reason for pregnancy was unrelated to repeat pregnancy by 18 months postpartum, but those who had wanted the study baby were less likely to undergo elective termination of a subsequent pregnancy and less likely to become pregnant by a different partner. The groups diverged at 24 months postpartum when those who wanted a baby were more likely to be married to the father of the baby, be financially supported by him, receive child care assistance from him, and have attempted or succeeded at breastfeeding the study child. Conclusion Self-reported reason for pregnancy reveals many important characteristics of pregnant adolescents both at the time of presentation and up to 2 years postpartum. Young women in this study who reported intentional pregnancy seem to fare better with regard to their financial status and their relationship with the father of the baby. PMID:10331837

    2014-01-01

    The "intentionality bias" refers to our automatic tendency to judge other people's actions to be intentional. In this experiment we extended research on this effect in two key ways. First, we developed a novel nonlinguistic task for assessing the intentionality bias. This task used video stimuli of ambiguous movements. Second, we investigated the relationship between the strength of this bias and schizotypy (schizophrenia-like symptoms in healthy individuals). Our results showed that the intentionality bias was replicated for the video stimuli and also that this bias is stronger in those individuals scoring higher on the schizotypy rating scales. Overall these findings lend further support for the existence of the intentionality bias. We also discuss the possible relevance of these findings for our understanding of certain symptoms of schizophrenic illness.

    2015-10-01

    Protective actions for hurricane threats are a function of the environmental and information context; individual and household characteristics, including cultural worldviews, past hurricane experiences, and risk perceptions; and motivations and barriers to actions. Using survey data from the Miami-Dade and Houston-Galveston areas, we regress individuals' stated evacuation intentions on these factors in two information conditions: (1) seeing a forecast that a hurricane will hit one's area, and (2) receiving an evacuation order. In both information conditions having an evacuation plan, wanting to keep one's family safe, and viewing one's home as vulnerable to wind damage predict increased evacuation intentions. Some predictors of evacuation intentions differ between locations; for example, Florida respondents with more egalitarian worldviews are more likely to evacuate under both information conditions, and Florida respondents with more individualist worldviews are less likely to evacuate under an evacuation order, but worldview was not significantly associated with evacuation intention for Texas respondents. Differences by information condition also emerge, including: (1) evacuation intentions decrease with age in the evacuation order condition but increase with age in the saw forecast condition, and (2) evacuation intention in the evacuation order condition increases among those who rely on public sources of information on hurricane threats, whereas in the saw forecast condition evacuation intention increases among those who rely on personal sources. Results reinforce the value of focusing hurricane information efforts on evacuation plans and residential vulnerability and suggest avenues for future research on how hurricane contexts shape decision making. © 2015 Society for Risk Analysis.

  10. Pine Island Glacier, Antarctica

    2001-01-01

    This pair of MISR images of the Pine Island Glacier in western Antarctica was acquired on December 12, 2000 during Terra orbit 5246. At left is a conventional, true-color image from the downward-looking (nadir) camera. The false-color image at right is a composite of red band data taken by the MISR forward 60-degree, nadir, and aftward 60-degree cameras, displayed in red, green, and blue colors, respectively. Color variations in the left (true-color) image highlight spectral differences. In the multi-angle composite, on the other hand, color variations act as a proxy for differences in the angular reflectance properties of the scene. In this representation, clouds show up as light purple. Blue to orange gradations on the surface indicate a transition in ice texture from smooth to rough. For example, the bright orange 'carrot-like' features are rough crevasses on the glacier's tongue. In the conventional nadir view, the blue ice labeled 'rough crevasses' and 'smooth blue ice' exhibit similar coloration, but the multi-angle composite reveals their different textures, with the smoother ice appearing dark purple instead of orange. This could be an indicator of different mechanisms by which this ice is exposed. The multi-angle view also reveals subtle roughness variations on the frozen sea ice between the glacier and the open water in Pine Island Bay.

    To the left of the 'icebergs' label are chunks of floating ice. Additionally, smaller icebergs embedded in the frozen sea ice are visible below and to the right of the label. These small icebergs are associated with dark streaks. Analysis of the illumination geometry suggests that these streaks are surface features, not shadows. Wind-driven motion and thinning of the sea ice in the vicinity of the icebergs is one possible explanation.

  13. Intentional systems: Review of neurodynamics, modeling, and robotics implementation

    2008-03-01

    We present an intentional neurodynamic theory for higher cognition and intelligence. This theory provides a unifying framework for integrating symbolic and subsymbolic methods as complementary aspects of human intelligence. Top-down symbolic approaches benefit from the vast experience with logical reasoning and with high-level knowledge processing in humans. Connectionist methods use bottom-up approach to generate intelligent behavior by mimicking subsymbolic aspects of the operation of brains and nervous systems. Neurophysiological correlates of intentionality and cognition include sequences of oscillatory patterns of mesoscopic neural activity. Oscillatory patterns are viewed as intermittent representations of generalized symbol systems, with which brains compute. These dynamical symbols are not rigid but flexible. They disappear soon after they emerged through spatio-temporal phase transitions. Intentional neurodynamics provides a solution to the notoriously difficult symbol grounding problem. Some examples of implementations of the corresponding dynamic principles are described in this review.

  16. Decoding Intention at Sensorimotor Timescales

    2014-01-01

    The ability to decode an individual's intentions in real time has long been a ‘holy grail’ of research on human volition. For example, a reliable method could be used to improve scientific study of voluntary action by allowing external probe stimuli to be delivered at different moments during development of intention and action. Several Brain Computer Interface applications have used motor imagery of repetitive actions to achieve this goal. These systems are relatively successful, but only if the intention is sustained over a period of several seconds; much longer than the timescales identified in psychophysiological studies for normal preparation for voluntary action. We have used a combination of sensorimotor rhythms and motor imagery training to decode intentions in a single-trial cued-response paradigm similar to those used in human and non-human primate motor control research. Decoding accuracy of over 0.83 was achieved with twelve participants. With this approach, we could decode intentions to move the left or right hand at sub-second timescales, both for instructed choices instructed by an external stimulus and for free choices generated intentionally by the participant. The implications for volition are considered. PMID:24523855

    Although empathic responses to stimuli with emotional contents may occur automatically, humans are capable to intentionally empathize with other individuals. Intentional empathy for others is even possible when they do not show emotional expressions. However, little is known about the neuronal mechanisms of this intentionally controlled empathic process. To investigate the neuronal substrates underlying intentional empathy, we scanned 20 healthy Chinese subjects, using fMRI, when they tried to feel inside the emotional states of neutral or angry faces of familiar (Asian) and unfamiliar (Caucasian) models. Skin color evaluation of the same stimuli served as a control task. Compared to a baseline condition, the empathy task revealed a network of established empathy regions, including the anterior cingulate cortex, bilateral inferior frontal cortex and bilateral anterior insula. The contrast of intentional empathy vs skin color evaluation, however, revealed three regions: the bilateral inferior frontal cortex, whose hemodynamic responses were independent of perceived emotion and familiarity and the right-middle temporal gyrus, whose activity was modulated by emotion but not by familiarity. These findings extend our understanding of the role of the inferior frontal cortex and the middle temporal gyrus in empathy by demonstrating their involvement in intentional empathy. PMID:21511824

    2009-06-01

    Electron acceleration via fast magnetic island coalescence that happens as quick magnetic reconnection triggering (QMRT) proceeds has been studied. We have carried out a three-dimensional full kinetic simulation of the Harris current sheet with a large enough simulation run for two magnetic islands coalescence. Due to the strong inductive electric field associated with the non-linear evolution of the lower-hybrid-drift instability and the magnetic island coalescence process observed in the non-linear stage of the collisionless tearing mode, electrons are significantly accelerated at around the neutral sheet and the subsequent X-line. The accelerated meandering electrons generated by the non-linear evolution of the lower-hybrid-drift instability are resulted in QMRT, and QMRT leads to fast magnetic island coalescence. As a whole, the reconnection triggering and its transition to large-scale structure work as an effective electron accelerator.

    2009-01-01

    This paper describes a control architecture and intent recognition approach for the real-time supervisory control of a powered lower limb prosthesis. The approach infers user intent to stand, sit, or walk, by recognizing patterns in prosthesis sensor data in real-time, without the need for instrumentation of the sound-side leg. Specifically, the intent recognizer utilizes time-based features extracted from frames of prosthesis signals, which are subsequently reduced to a lower dimensionality (for computational efficiency). These data are initially used to train intent models, which classify the patterns as standing, sitting, or walking. The trained models are subsequently used to infer the user’s intent in real-time. In addition to describing the generalized control approach, this paper describes the implementation of this approach on a single unilateral transfemoral amputee subject, and demonstrates via experiments the effectiveness of the approach. In the real-time supervisory control experiments, the intent recognizer identified all 90 activity mode transitions, switching the underlying middle level controllers without any perceivable delay by the user. The intent recognizer also identified six activity mode transitions, which were not intended by the user. Due to the intentional overlapping functionality of the middle level controllers, the incorrect classifications neither caused problems in functionality, nor were perceived by the user.

    The first comprehensive measurements of plasma flows and fluctuations nearby static magnetic islands driven by resonant magnetic perturbations are presented. These experiments were performed using multiple Langmuir probe arrays on the edge plasmas of the J-TEXT tokamak. Controlled variations of the island size and location are explored. This study aims to understand the interaction between turbulence and magnetic islands, and to elucidate magnetic island effects on edge turbulence and flow intensity profiles, edge electric fields, and thus confinement regime transitions. Turbulence and low frequency flows (LFFs) all drop inside the magnetic island, but increase at its boundary, as island width increases. The geodesic acoustic mode is damped in most of the edge area with magnetic islands. The sign of the radial electric field changes from negative to positive within the islands. The gradient of turbulent stresses vanishes at the island center, and becomes steeper at the boundaries of the islands. The particle transport induced by the turbulence is reduced inside the magnetic islands. The magnetic island effects on flows and turbulence can lead to an increase in LFFs and enhance Reynolds stresses near the last closed flux surface (LCFS). A stronger radial electric field layer can be formed near the LCFS when magnetic islands are present. The results suggest that magnetic islands can be used as a tool to enhance edge turbulence and flows, edge electric fields, and thus to trigger confinement regime transitions.

    The flood of scientific information increases the risk of research findings distortion. The authors brought attention to the possible pitfalls of statistical inference in biomedical research. Due to intentional or non-intentional errors in study design and size, data collection and inappropriate statistical analysis some of research findings are false or exaggerated. Researchers excessively motivated to publish all possible study results sometimes seek any possible way to achieve p-value less than 0.05. False-positive study results can be obtained in underpowered studies, excessive flexibility in study designs and participants recruitment, probing different control groups, creating special subgroups or changing statistical tests.

    2013-01-01

    Although significant advances have been made in our understanding of the neural basis of action observation and intention understanding in the last few decades by studies demonstrating the involvement of a specific brain network (action observation network; AON), these have been largely based on experimental studies in which people have been considered as strictly isolated entities. However, we, as social species, spend much more of our time performing actions interacting with others. Research shows that a person's position along the continuum of perceived social isolation/bonding to others is associated with a variety of physical and mental health effects. Thus, there is a crucial need to better understand the neural basis of intention understanding performed in interpersonal and emotional contexts. To address this issue, we performed a meta-analysis using of functional magnetic resonance imaging (fMRI) studies over the past decade that examined brain and cortical network processing associated with understanding the intention of others actions vs. those associated with passionate love for others. Both overlapping and distinct cortical and subcortical regions were identified for intention and love, respectively. These findings provide scientists and clinicians with a set of brain regions that can be targeted for future neuroscientific studies on intention understanding, and help develop neurocognitive models of pair-bonding.

    1988-01-01

    The development of offshore oil and gas resources in the Arctic waters of Alaska requires offshore structures which successfully resist the lateral forces due to moving, drifting ice. Ice islands are floating, a tabular icebergs, up to 60 meters thick, of solid ice throughout their thickness. The ice islands are thus regarded as the strongest ice features in the Arctic; fixed offshore structures which can directly withstand the impact of ice islands are possible but in some locations may be so expensive as to make oilfield development uneconomic. The resolution of the ice island problem requires two research steps: (1) calculation of the probability of interaction between an ice island and an offshore structure in a given region; and (2) if the probability if sufficiently large, then the study of possible interactions between ice island and structure, to discover mitigative measures to deal with the moving ice island. The ice island research conducted during the 1983-1988 interval, which is summarized in this report, was concerned with the first step. Monte Carlo simulations of ice island generation and movement suggest that ice island lifetimes range from 0 to 70 years, and that 85% of the lifetimes are less then 35 years. The simulation shows a mean value of 18 ice islands present at any time in the Arctic Ocean, with a 90% probability of less than 30 ice islands. At this time, approximately 34 ice islands are known, from observations, to exist in the Arctic Ocean, not including the 10-meter thick class of ice islands. Return interval plots from the simulation show that coastal zones of the Beaufort and Chukchi Seas, already leased for oil development, have ice island recurrences of 10 to 100 years. This implies that the ice island hazard must be considered thoroughly, and appropriate safety measures adopted, when offshore oil production plans are formulated for the Alaskan Arctic offshore. 132 refs., 161 figs., 17 tabs.

    This nearly vertical view of the Canary Archipelago (28.5N, 16.5W) shows five of the seven islands: Grand Canary, Tenerife, Gomera, Hierro and La Palma. The largest island in view is Tenerife. Island cloud wakes evident in this photo are the result of southerly winds giving rise to cloud banks on the lee side especially on Tenerife which has the highest volcanic peaks. Island water wakes and internal waves are also evident but not as apparent.

    The Diomede Islands consisting of the western island Big Diomede (also known as Imaqliq, Nunarbuk or Ratmanov Island), and the eastern island Little Diomede (also known as Krusenstern Island or Inaliq), are two rocky islands located in the middle of the Bering Strait between Russia and Alaska. The islands are separated by an international border and the International Date Line which is approximately 1.5 km from each island; you can look from Alaska into tomorrow in Russia. At the closest land approach between the United States, which controls Little Diomede, and Russia, which controls Big Diomede, they are 3 km apart. Little Diomede Island constitutes the Alaskan City of Diomede, while Big Diomede Island is Russia's easternmost point. The first European to reach the islands was the Russian explorer Semyon Dezhnev in 1648. The text of the 1867 treaty finalizing the sale of Alaska uses the islands to designate the border between the two nations.

    The image was acquired July 8, 2000, covers an area of 13.5 x 10.8 km, and is located at 65.8 degrees north latitude, 169 degrees west longitude.

    The percentage of endemic species of birds on islands increases with island area at a double logarithmic rate. This relation is apparently due to extinction, which is more rapid the smaller the island. The turnover resulting from extinction and replacement appears to be far more rapid than hitherto suspected.

    We know a great deal about the neurophysiological mechanisms supporting instrumental actions, i.e., actions designed to alter the physical state of the environment. In contrast, little is known about our ability to select communicative actions, i.e., actions directly designed to modify the mental state of another agent. We have recently provided novel empirical evidence for a mechanism in which a communicator selects his actions on the basis of a prediction of the communicative intentions that an addressee is most likely to attribute to those actions. The main novelty of those findings was that this prediction of intention recognition is cerebrally implemented within the intention recognition system of the communicator, is modulated by the ambiguity in meaning of the communicative acts, and not by their sensorimotor complexity. The characteristics of this predictive mechanism support the notion that human communicative abilities are distinct from both sensorimotor and linguistic processes. PMID:21151781

  3. Morality, Intentionality, and Intergroup Attitudes

    PubMed Central

    Killen, Melanie; Rizzo, Michael T.

    2015-01-01

    Morality is at the core of what it means to be social. Moral judgments require the recognition of intentionality, that is, an attribution of the target’s intentions towards another. Most research on the origins of morality has focused on intragroup morality, which involves applying morality to individuals in one’s own group. Yet, increasingly, there has been new evidence that beginning early in development, children are able to apply moral concepts to members of an outgroup as well, and that this ability appears to be complex. The challenges associated with applying moral judgments to members of outgroups includes understanding group dynamics, the intentions of others who are different from the self, and having the capacity to challenge stereotypic expectations of others who are different from the ingroup. Research with children provides a window into the complexities of moral judgment and raises new questions, which are ripe for investigations into the evolutionary basis of morality. PMID:25717199

  4. Poly(ethylene glycol) self-assembled monolayer island growth.

    Rundqvist, Jonas; Hoh, Jan H; Haviland, David B

    2005-03-29

    Here, we report a study of the morphology and growth dynamics of a self-assembled monolayer (SAM) of the amide containing poly(ethylene glycol) (PEG) thiol (CH3O(CH2CH2O)17NHCO(CH2)2SH) on atomically flat Au(111) surfaces. SAM growth from a 20 muM ethanolic solution reveals island growth through three distinct steps: island nucleation, island growth, and coalescence. The coalescence-step, filling voids in the SAM, is by far slowest. The fine structure study reveals dendritic island formation, an observation which can be explained by attractive intermolecular interactions and surface diffusion-limited aggregation. We have also observed a change in the island height, which peaks during the island growth phase. This height change can be associated with a molecular conformational transition.

    Situated 1670 km northeast of Sydney, Norfolk Island is an Australian Territory. It was permanently settled in 1856 by Pitcairn Islanders who were descendants of Tahitians and HMS Bounty mutineers. In 1979 Norfolk was granted limited self-government: the island elects a government that runs most of the island's affairs. In March, a local council replaced the local government, and the island was given closer financial ties to Australia. The image was acquired November 12, 2009, covers an area of 9 x 11 km, and is located at 29 degrees south, 168 degrees east. http://photojournal.jpl.nasa.gov/catalog/PIA19463

  7. Predictable evolution toward flightlessness in volant island birds

    Wright, Natalie A.; Steadman, David W.; Witt, Christopher C.

    2016-01-01

    Birds are prolific colonists of islands, where they readily evolve distinct forms. Identifying predictable, directional patterns of evolutionary change in island birds, however, has proved challenging. The “island rule” predicts that island species evolve toward intermediate sizes, but its general applicability to birds is questionable. However, convergent evolution has clearly occurred in the island bird lineages that have undergone transitions to secondary flightlessness, a process involving drastic reduction of the flight muscles and enlargement of the hindlimbs. Here, we investigated whether volant island bird populations tend to change shape in a way that converges subtly on the flightless form. We found that island bird species have evolved smaller flight muscles than their continental relatives. Furthermore, in 366 populations of Caribbean and Pacific birds, smaller flight muscles and longer legs evolved in response to increasing insularity and, strikingly, the scarcity of avian and mammalian predators. On smaller islands with fewer predators, birds exhibited shifts in investment from forelimbs to hindlimbs that were qualitatively similar to anatomical rearrangements observed in flightless birds. These findings suggest that island bird populations tend to evolve on a trajectory toward flightlessness, even if most remain volant. This pattern was consistent across nine families and four orders that vary in lifestyle, foraging behavior, flight style, and body size. These predictable shifts in avian morphology may reduce the physical capacity for escape via flight and diminish the potential for small-island taxa to diversify via dispersal. PMID:27071105

  8. Control of paleoshorelines by trench forebulge uplift, Loyalty Islands

    NASA Astrophysics Data System (ADS)

    Dickinson, William R.

    2013-07-01

    Unlike most tropical Pacific islands, which lie along island arcs or hotspot chains, the Loyalty Islands between New Caledonia and Vanuatu owe their existence and morphology to the uplift of pre-existing atolls on the flexural forebulge of the New Hebrides Trench. The configuration and topography of each island is a function of distance from the crest of the uplifted forebulge. Both Maré and Lifou are fully emergent paleoatolls upon which ancient barrier reefs form highstanding annular ridges that enclose interior plateaus representing paleolagoon floors, whereas the partially emergent Ouvea paleoatoll rim flanks a drowned remnant lagoon. Emergent paleoshoreline features exposed by island uplift include paleoreef flats constructed as ancient fringing reefs built to past low tide levels and emergent tidal notches incised at past high tide levels. Present paleoshoreline elevations record uplift rates of the islands since last-interglacial and mid-Holocene highstands in global and regional sea levels, respectively, and paleoreef stratigraphy reflects net Quaternary island emergence. The empirical uplift rates vary in harmony with theoretical uplift rates inferred from the different positions of the islands in transit across the trench forebulge at the trench subduction rate. The Loyalty Islands provide a case study of island environments controlled primarily by neotectonics.

  10. Generalized model of island biodiversity

    Kessler, David A.; Shnerb, Nadav M.

    2015-04-01

    The dynamics of a local community of competing species with weak immigration from a static regional pool is studied. Implementing the generalized competitive Lotka-Volterra model with demographic noise, a rich dynamics with four qualitatively distinct phases is unfolded. When the overall interspecies competition is weak, the island species recapitulate the mainland species. For higher values of the competition parameter, the system still admits an equilibrium community, but now some of the mainland species are absent on the island. Further increase in competition leads to an intermittent "disordered" phase, where the dynamics is controlled by invadable combinations of species and the turnover rate is governed by the migration. Finally, the strong competition phase is glasslike, dominated by uninvadable states and noise-induced transitions. Our model contains, as a special case, the celebrated neutral island theories of Wilson-MacArthur and Hubbell. Moreover, we show that slight deviations from perfect neutrality may lead to each of the phases, as the Hubbell point appears to be quadracritical.

  14. Intentional learning: A concept analysis.

    PubMed

    2017-07-19

    To use a concept analysis to determine a clear definition of the term "intentional learning" for use in nursing. The term intentional learning has been used for years in educational, business, and even nursing literature. It has been used to denote processes leading to higher order thinking and the ability to use knowledge in new situations; both of which are important skills to develop in nursing students. But the lack of a common, accepted definition of the term makes it difficult for nurse educators to base instruction and learning experiences on or to evaluate its overall effectiveness in educating students for diverse, fast-paced clinical practices. A concept analysis following the eight-step method developed by Walker and Avant (2011). Empirical and descriptive literature.  Five defining attributes were identified: (1) self-efficacy for learning, (2) active, effortful, and engaged learning, (3) mastery of goals where learning is the goal, (4) self-directed learning, and (5) self-regulation of learning. Through this concept analysis, nursing will have a clear definition of intentional learning. This will enable nurse educators to generate, evaluate, and test learning experiences that promote further development of intentional learning in nursing students. Nurses in practice will also be able to evaluate if the stated benefits are demonstrated and how this impacts patient care and outcomes. © 2017 Wiley Periodicals, Inc.

  19. The two sides of goal intentions: Intention self-concordance and intention strength as predictors of physical activity.

    PubMed

    Fuchs, Reinhard; Seelig, Harald; Göhner, Wiebke; Schlatterer, Martina; Ntoumanis, Nikos

    2017-01-01

    The present research introduces an extended conceptualisation of self-concordance, which is considered an attribute not only of goals, but also of goal intentions. Based on a corresponding operationalisation, we investigate the interplay of both intention strength and intention self-concordance in the prediction of physical activity. Data were taken from a longitudinal study of 134 obese people who were asked to fill out a questionnaire three times every six months. Physical activity and intention self-concordance were measured by validated scales. Intentions strength was assessed by an item typically employed in the extant literature. Logistic regression analyses and path analyses showed both intention strength and self-concordance to be significant predictors of changes in physical activity over time. Additional analyses found self-efficacy to be a significant predictor of intention strength and self-concordance; for outcome expectations this was not the case. Findings support the idea that intention strength and self-concordance are two critical facets of a goal intention that need to be considered in the prediction of physical activity participation. Whereas intention strength refers to the degree of determination with which a goal intention is adopted, self-concordance rather captures the quality of this intention.

The species list presented here includes the names of all ant species recorded from the islands that are available in the literature together with specimen records from several museum collections and new records from our 2008 Makira field expedition. All the names of described species presented are valid in accordance with the most recent Formicidae classification. In total, the checklist is composed of 237 species and subspecies (including 30 morphospecies) in 59 genera representing nine subfamilies. We report that the recent field expedition added 67 new species records to Makira and 28 new species records to the Solomon Islands. Our research recovered species occurrence records for 32 individual islands and five island groups. The five islands with the highest number of recorded species are: Makira (142 spp.), Guadalcanal (107 spp.), Malaita (70 spp.), Santa Isabel (68 spp.), and Rennell (66 spp.). Based on our results, we discuss the taxonomic composition of the archipelago's ant fauna, which islands are most in need of additional sampling, and the importance of establishing biodiversity baselines before environmental threats such as the invasive ant Wasmannia auropunctata cause irrevocable harm to the native biodiversity.

    Decoding the intentions of other people based on non-linguistic cues such as their body movement is a major requirement of many jobs. Whether it is maintaining security at an airport or negotiating with locals in a foreign country, there is a need to maximize the effectiveness of training or real-time performance in this decoding process. This review considers the potential utility of neuroergonomic solutions, and in particular, of electroencephalographic (EEG) methods for augmenting action understanding. Focus is given to body movements and hand-object interactions, where there is a rapid growth in relevant science. The interpretation of EEG-based signals is reinforced by a consideration of functional magnetic resonance imaging experiments demonstrating underlying brain mechanisms that support goal oriented action. While no EEG method is currently implemented as a practical application for enhancing the understanding of unspoken intentions, there are a number of promising approaches that merit further development.

This review considers the potential utility of neuroergonomic solutions, and in particular, of electroencephalographic (EEG) methods for augmenting action understanding. Focus is given to body movements and hand-object interactions, where there is a rapid growth in relevant science. The interpretation of EEG-based signals is reinforced by a consideration of functional magnetic resonance imaging experiments demonstrating underlying brain mechanisms that support goal oriented action. While no EEG method is currently implemented as a practical application for enhancing the understanding of unspoken intentions, there are a number of promising approaches that merit further development.

    Intentions, including their temporal properties and semantic content, are receiving increased attention, and neuroscientific studies in humans vary with respect to the topography of intention-related neural responses. This may reflect the fact that the kind of intentions investigated in one study may not be exactly the same kind investigated in the other. Fine-grained intention taxonomies developed in the philosophy of mind may be useful to identify the neural correlates of well-defined types of intentions, as well as to disentangle them from other related mental states, such as mere urges to perform an action. Intention-related neural signals may be exploited by brain-machine interfaces (BMIs) that are currently being developed to restore speech and motor control in paralyzed patients. Such BMI devices record the brain activity of the agent, interpret (“decode”) the agent’s intended action, and send the corresponding execution command to an artificial effector system, e.g., a computer cursor or a robotic arm. In the present paper, we evaluate the potential of intention concepts from philosophy of mind to improve the performance and safety of BMIs based on higher-order, intention-related control signals. To this end, we address the distinction between future-, present-directed, and motor intentions, as well as the organization of intentions in time, specifically to what extent it is sequential or hierarchical. This has consequences as to whether these different types of intentions can be expected to occur simultaneously or not. We further illustrate how it may be useful or even necessary to distinguish types of intentions exposited in philosophy, including yes- vs. no-intentions and oblique vs. direct intentions, to accurately decode the agent’s intentions from neural signals in practical BMI applications.

  13. Experimental Evaluation of PV Inverter Anti-Islanding with Grid Support Functions in Multi-Inverter Island Scenarios

    As PV and other DER systems are connected to the grid at increased penetration levels, island detection may become more challenging for two reasons: 1.) In islands containing many DERs, active inverter-based anti-islanding methods may have more difficulty detecting islands because each individual inverter's efforts to detect the island may be interfered with by the other inverters in the island. 2.) The increasing numbers of DERs are leading to new requirements that DERs ride through grid disturbances and even actively try to regulate grid voltage and frequency back towards nominal operating conditions. These new grid support requirements may directly or indirectly interfere with anti-islanding controls. This report describes a series of tests designed to examine the impacts of both grid support functions and multi-inverter islands on anti-islanding effectiveness. Crucially, the multi-inverter anti-islanding tests described in this report examine scenarios with multiple inverters connected to multiple different points on the grid. While this so-called 'solar subdivision' scenario has been examined to some extent through simulation, this is the first known work to test it using hardware inverters. This was accomplished through the use of power hardware-in-the-loop (PHIL) simulation, which allows the hardware inverters to be connected to a real-time transient simulation of an electric power system that can be easily reconfigured to test various distribution circuit scenarios. The anti-islanding test design was a modified version of the unintentional islanding test in IEEE Standard 1547.1, which creates a balanced, resonant island with the intent of creating a highly challenging condition for island detection. Three common, commercially available single-phase PV inverters from three different manufacturers were tested. The first part of this work examined each inverter individually using a series of pure hardware resistive-inductive-capacitive (RLC) resonant load

    Large market participants (LMPs) must often execute trades while keeping their intentions secret. Sometimes secrecy is required before trades are completed to prevent other traders from anticipating (and exploiting) the price impact of their trades. This is known as "front-running". In other cases, LMPs with proprietary trading strategies wish to keep their positions secret even after trading because their strategies and positions contain valuable information. LMPs include hedge funds, mutual funds, and other specialized market players.

    The natural occurrence of significant disturbances to the operation of insular ecosystems has tended to be downplayed in the development of island ecological theory. Despite the importance of events such as Hurricane Hugo, which in 1989 affected islands in the Caribbean, islands that are disturbed tend to be viewed as deviants from the `true path' described by equilibrium models. However, particularly with organisms of long generation times, it is questionable whether such models are applicable. This may be as important for wildlife managers to take account of as for theorists. Disturbance regime should be incorporated into island ecological models alongside other ecological factors structuring colonization patterns and turnover.

  19. Slow motion increases perceived intent

    Caruso, Eugene M.; Burns, Zachary C.; Converse, Benjamin A.

    To determine the appropriate punishment for a harmful action, people must often make inferences about the transgressor’s intent. In courtrooms and popular media, such inferences increasingly rely on video evidence, which is often played in “slow motion.” Four experiments (n = 1,610) involving real surveillance footage from a murder or broadcast replays of violent contact in professional football demonstrate that viewing an action in slow motion, compared with regular speed, can cause viewers to perceive an action as more intentional. This slow motion intentionality bias occurred, in part, because slow motion video caused participants to feel like the actor had more time to act, even when they knew how much clock time had actually elapsed. Four additional experiments (n = 2,737) reveal that allowing viewers to see both regular speed and slow motion replay mitigates the bias, but does not eliminate it. We conclude that an empirical understanding of the effect of slow motion on mental state attribution should inform the life-or-death decisions that are currently based on tacit assumptions about the objectivity of human perception.

  3. Thermodynamic model of coherent island formation on vicinal substrate

    A thermodynamic model has been proposed to address the formation of coherent island on the vicinal substrate. The morphological transition from square based island to elongated based one with various substrate misorientations is described. The initial stage of nucleation and growth process of islands in Stranski–Krastanow system is studied by taking into account the elastic deformations and the change of energy in the case of two-dimensional growth mode. The theoretical analysis shows the minimum nucleation barrier of island is on the decrease with increment of substrate misorientation, which means the nucleation of island on vicinal substrate is more favorable than that on flat substrate. By using the fitting data of experimental results done by Persichetti et al., [Phys. Rev. Lett. 104, 036104 (2010) and Phys. Rev. B 82, 121309(R) (2010)], we provide a meaningful explanation of the experimental observations.

    The first-order phase separation in a thin fluid film was simulated using a two-dimensional lattice-Boltzman model (LBM) with fluid-fluid interactions. The effects of the domain size on the intermediate asymptotic island size distribution were also discussed. It was observed that the overall process is dominated by coalescence which is independent of island mass. The results show that the combined effects of growth, coalescence, and Ostwald ripening control the phase transition process in the LBM simulations.

    1992-01-01

    The Hawaiian Islands are an ideal location to study basaltic sand provenance in that they are a series of progressively older basaltic shield volcanoes with arid to humid microclimates. Sixty-two sand samples were collected from beaches on the islands of Hawaii, Maui, Oahu and Kauai and petrographically analyzed. The major sand components are calcareous bioclasts, volcanic lithic fragments, and monomineralic grains of dense minerals and plagioclase. Proportions of these components vary from island to island, with bioclastic end members being more prevalent on older islands exhibiting well-developed fringing reef systems and volcanic end members more prevalent on younger, volcanically active islands. Climatic variations across the island of Hawaii are reflected in the percentage of weathered detritus, which is greater on the wetter, northern side of the island. The groundmass of glassy, basaltic lithics is predominantly black tachylite, with lesser brown sideromelane; microlitic and lathwork textures are more common than holohyaline vitric textures. Other common basaltic volcanic lithic fragments are holocrystalline aggregates of silt-sized pyroxene or olivine, opaque minerals and plagioclase. Sands derived from alkalic lavas are texturally and compositionally indistinguishable from sands derived from tholeiitic lavas. Although Hawaiian basaltic sands overlap in composition with magmatic arc-derived sands in terms of their relative QFL, QmPK and LmLvLs percentages, they are dissimilar in that they lack felsic components and are more enriched in lathwork volcanic lithic fragments, holocrystalline volcanic lithic fragments, and dense minerals.

    The ability to learn new tasks rapidly is a prominent characteristic of human behaviour. This ability relies on flexible cognitive systems that adapt in order to encode temporary programs for processing non-automated tasks. Previous functional imaging studies have revealed distinct roles for the lateral frontal cortices (LFCs) and the ventral striatum in intentional learning processes. However, the human LFCs are complex; they house multiple distinct sub-regions, each of which co-activates with a different functional network. It remains unclear how these LFC networks differ in their functions and how they coordinate with each other, and the ventral striatum, to support intentional learning. Here, we apply a suite of fMRI connectivity methods to determine how LFC networks activate and interact at different stages of two novel tasks, in which arbitrary stimulus-response rules are learnt either from explicit instruction or by trial-and-error. We report that the networks activate en masse and in synchrony when novel rules are being learnt from instruction. However, these networks are not homogeneous in their functions; instead, the directed connectivities between them vary asymmetrically across the learning timecourse and they disengage from the task sequentially along a rostro-caudal axis. Furthermore, when negative feedback indicates the need to switch to alternative stimulus–response rules, there is additional input to the LFC networks from the ventral striatum. These results support the hypotheses that LFC networks interact as a hierarchical system during intentional learning and that signals from the ventral striatum have a driving influence on this system when the internal program for processing the task is updated.

    Objective To identify psychosocial differences between sexually experienced male adolescents who indicate intentions to get someone pregnant and those who do not. Methodology Cross-sectional study of 101 sexually experienced adolescent males recruited from an STD clinic in northern California. Student’s t-tests and regressions examined psychosocial differences between males who reported any intention versus no intention to get someone pregnant in the next six months. ANOVAs examined differences among different combinations of pregnancy plans/likelihood. Results Adolescents’ reports of their plans for getting someone pregnant differed from their assessments of the likelihood that they would do so (χ2 = 24.33, df = 1, p < .0001). Attitudes toward pregnancy and participants’ mothers’ educational attainment differentiated those with clear pregnancy intentions (Planning, and Likely) from those with clear intentions to avoid pregnancy (Not Planning & Not Likely) Conclusions To reduce the rates of adolescent childbearing, males’ pregnancy intentions must be assessed and asked about in multiple ways.

  19. Distinct electrophysiological potentials for intention in action and prior intention for action.

    PubMed

    Vinding, Mikkel C; Jensen, Mads; Overgaard, Morten

    2014-01-01

    The role of conscious intention in relation to motoric movements has become a major topic of investigation in neuroscience. Traditionally, reports of conscious intention have been compared to various features of the readiness-potential (RP)--an electrophysiological signal that appears before voluntary movements. Experiments, however, tend to study intentions in immediate relation to movements (proximal intentions), thus ignoring other aspects of intentions such as planning or deciding in advance of movement (distal intentions). The current study examines the difference in electrophysiological activity between proximal intention and distal intention, using electroencephalography (EEG). Participants had to form an intention to move and then wait 2.5 sec before performing the actual movement. In this way, the electrophysiological activity related to forming a conscious intention was separated from any confounding activity related to automated motor activity. This was compared to conditions in which participants had to act as soon as they had the intention and a condition where participants acted upon an external cue 2.5 sec prior to movement. We examined the RP for the three conditions. No difference was found in early RP, but late RP differed significantly depending on the type of intention. In addition, we analysed signals during a longer time-interval starting before the time of distal intention formation until after the actual movement concluded. Results showed a slow negative electrophysiological "intention potential" above the mid-frontal areas at the time participants formed a distal intention. This potential was only found when the distal intention was self-paced and not when the intention was formed in response to an external cue. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2005-01-01

    To describe the job withdrawal intentions of a nationwide sample of Certified Pharmacy Technicians (CPhTs). Cross-sectional descriptive design. A random sample of 3,200 CPhTs whose names and contact information were acquired from the Pharmacy Technician Certification Board. Mailed survey. Responses to questions eliciting job withdrawal intentions, reasons for remaining/staying with the employer, and various quality of worklife attitudes. Employment intentions were regressed over quality of worklife and practice environment variables in a forward-conditional logistic regression procedure. Nearly 4 in 5 respondents indicated intentions to remain with the current employer during the next 12 months. Relationships with coworkers, good benefits, and work schedule were frequently cited as reasons to stay. Poor salary, lack of advancement opportunity, and insufficient staffing were cited frequently as factors among those indicating intentions to leave. Mean hourly wages differed among respondents with intention to leave due to salary, those not citing salary as a reason to remain or leave, and those citing salary as a reason for staying. Intention to remain was associated with higher pay, perceived employer support, number of years with the current employer, and lower career turnover intentions, with organizational commitment acting as a powerful mediator for all of the variables. Differences in CPhTs' future employment intentions were described more comprehensively by perceptions of the employing organization than by perceptions of managers/supervisors and coworkers or personal/work environment variables. Implications for pharmacy organizations are discussed.

  2. Assessing communicative intents: a situated pragmatics approach.

    Hewitt, L E

    2000-01-01

    The analysis of communicative intents is described as it has developed over time, beginning with J.L. Austin's work published in 1975. Recommendations for best practice are offered in which a situated approach is advocated. Key elements of this approach are a focus on contextual variables and open-ended, rather than list-oriented, assessments of range of intents. It is argued that intents must be assessed relative to the environment, with documentation of environmental variables such as barriers to communicative opportunity. Further, caution is urged in using lists of intents as the sole guide to analysis, because such lists serve to limit awareness of individual differences and multifunctionality of utterances.

  3. On "intention" in the definition of suicide.

    PubMed

    2006-10-01

    The need for a comprehensive nomenclature in suicidology is now well recognized. In this paper the focus is on the issue of intention, which is identified as an essential aspect of any definition of suicide and suicidal behavior primarily because of its distinction from accidental behavior. The distinction between the retrospective perspective of motives versus the prospective perspective of intentions is highlighted, and I argue that the latter is more closely related to suicidal behavior. Finally, while motives and intentions tend to be used together in research, there is a need for sound research to clarify the roles of intentions in order to better understand suicide and attempted suicide.

  8. Soils and vegetation of Santa Barbara Island, Channel Islands National Park, California, USA

    NASA Astrophysics Data System (ADS)

    Halvorson, William L.; Fenn, Dennis B.; Allardice, William R.

    1988-01-01

    The multifaceted development of an erosion surface on Santa Barbara Island, Channel Islands National Park, California, has led to this study of the relationship between soils and vegetation. A dry Mediterranean climate and past attempts at farming and introductions of alien species have led to vegetative degradation accompanied by both gully and surface erosion. Soil and vegetation analyses show this erosion to be in a location of transition. The soils are Typic Chromoxererts (Vertisol Order) with high clay, salinity, and sodium contents. The vegetation is ecotonal in nature, grading from a principally alien annual grassland with Avena fatua and Atriplex semibaccata to a shrub community dominated by the native Suaeda californica. Management toward revegetation and stabilization of this island ecosystem will be difficult with high clay, saline-sodic soils and disturbed vegetation.

  9. Dengue transmission in the small-island setting: investigations from the Caribbean island of Grenada.

    Schiøler, Karin L; Macpherson, Calum N

    2009-08-01

    The Caribbean region has experienced a major surge in dengue activity in recent decades. Yet, for many, and especially the smaller islands, the true extent and general epidemiology of dengue transmission remains unclear because of inadequate systems of surveillance and reporting. We established an active surveillance system supported by laboratory-based diagnosis on the small island of Grenada, from January 2001 through June 2002. The surveillance data provided evidence of three distinct modes of disease dynamics in the form of low endemic, pre-epidemic, and overt epidemic transmission of mostly benign dengue fever. A shift in serotype activity and modal age was evident during the noted transition, with the more densely populated south end of the island presenting the focus of transmission.

    Effectively transitioning science knowledge to useful applications relevant to space weather has become important. The effort to transition scientific knowledge to a useful application is not a research nor is it operations, but an activity that connects two. Successful transitioning must be an intentional effort with a clear goal and measureable outcome. This talk will present proven methodologies that have been demonstrated to be effective, and how in the current environment those can be applied to space weather transition efforts.

  13. RTGs on Transit

    NASA Astrophysics Data System (ADS)

    Dassoulas, John; McNutt, Ralph L.

    2007-01-01

    Transit, the US Navy's Navigation Satellite System was conceived at the Applied Physics Laboratory in 1957 by observing the Doppler shift while tracking Sputnik I. As spacecraft development proceeded there was concern about the ability of batteries to maintain the hermetic seal over a 5-year operational life requirement; therefore, alternate energy sources were investigated. The radioisotope thermoelectric generator (RTG) concept was pursued and resulted in the launch of SNAP 3s, providing partial power on both Transit 4A and 4B. SNAP 9s provided full power on three Transit 5BNs. All launches occurred in the early 1960s. When the U.S. conducted the high altitude nuclear test from Johnson Island, several spacecraft were lost due to artificial enhancement of charged particles in the Earth's magnetosphere resulting in rapid degradation of solar cell power production. This led to the decision to have both an RTG and Solar cell/battery design for Transit power systems; hence, a new RTG design, with a separable heat source and radiative coupling to the thermoelectric elements, was flown on TRIAD. This pioneering effort provided the impetus for future RTGs on interplanetary spacecraft. This paper describes the origin and purpose of the Transit program and provides details on the five satellites in that program that were powered by the first American RTGs used in space. The rationale and some of the challenges inherent in that use are also described.

The islands perturb the prevailing northeasterly winds producing extensive cloud wakes in the lee of the islands. Photo experts feel that atmospheric haze in the Hawaii wake is probably a result of the continuing eruptions of Kilauea volcano on the southeast coast. From the lower right corner in a diagonal directed upward to the north are the islands of Nihau, Kauai, Oahu, Molokai, Lanai, Maui, Kahoolawe, and Hawaii. This photo was shown during the post-flight press conference on October 11, 1988 by the STS-26 astronauts, who at one time during the flight wore Hawaiian attire to pay tribute to the working staff of the Hawaii tracking station.

  7. Transition from ultra-enriched to ultra-depleted primary MORB melts in a single volcanic suite (Macquarie Island, SW Pacific): Implications for mantle source, melting process and plumbing system

    NASA Astrophysics Data System (ADS)

    Husen, Anika; Kamenetsky, Vadim S.; Everard, John L.; Kamenetsky, Maya B.

    2016-07-01

    Compositional diversity of basalts forming the oceanic floor is attributed to a variety of factors such as mantle heterogeneities, melting conditions, mixing of individual melt batches, as well as fractionation and assimilation processes during magma ascent and emplacement. In this study the compositional range and origin of mid-ocean ridge basalts (MORB) is approached by petrological, mineralogical and geochemical studies of the Miocene Macquarie Island ophiolite, an uplifted part of the Macquarie Ridge at the boundary between the Australian and Pacific plates. In this study, earlier results on the enriched to ultra-enriched (La/Sm 1.4-7.9), isotopically homogeneous basaltic glasses are complemented by the compositions of olivine-phyric rocks, principal phenocrystic minerals and Cr-spinel hosted melt inclusions. Studied olivine, clinopyroxene and Cr-spinel phenocrysts are among the most primitive known for MORB (85-91 mol% forsterite in olivine, 81-91 Mg# in clinopyroxene, and 66-77 Mg# and 34-60 Cr# in spinel) and represent primary and near-primary compositions of their parental melts. Geochemical characteristics of the liquids parental to clinopyroxene (La/Sm 0.8-6.3) and Cr-spinel (La/Sm 0.4-5) partly overlap with those of the basaltic glasses, but also strongly advocate the role of depleted to ultra-depleted primary melts in the origin of the Macquarie Island porphyritic rocks. The trace element composition of olivine phenocrysts and the systematics of rare-earth elements in glasses, melt inclusions, and clinopyroxene provide evidence for a peridotitic composition of the source mantle. Our data supports the mechanism of fractional "dynamic" melting of a single mantle peridotite producing individual partial melt batches with continuously changing compositions from ultra-enriched towards ultra-depleted. The incipient enriched melt batches, represented by basaltic glasses in this study, may erupt without significant modification, whereas consecutively derived

  11. Complementary systems for understanding action intentions.

    PubMed

    de Lange, Floris P; Spronk, Marjolein; Willems, Roel M; Toni, Ivan; Bekkering, Harold

    2008-03-25

    How humans understand the intention of others' actions remains controversial. Some authors have suggested that intentions are recognized by means of a motor simulation of the observed action with the mirror-neuron system [1-3]. Others emphasize that intention recognition is an inferential process, often called "mentalizing" or employing a "theory of mind," which activates areas well outside the motor system [4-6]. Here, we assessed the contribution of brain regions involved in motor simulation and mentalizing for understanding action intentions via functional brain imaging. Results show that the inferior frontal gyrus (part of the mirror-neuron system) processes the intentionality of an observed action on the basis of the visual properties of the action, irrespective of whether the subject paid attention to the intention or not. Conversely, brain areas that are part of a "mentalizing" network become active when subjects reflect about the intentionality of an observed action, but they are largely insensitive to the visual properties of the observed action. This supports the hypothesis that motor simulation and mentalizing have distinct but complementary functions for the recognition of others' intentions.

  14. Mind-Wandering With and Without Intention.

    PubMed

    Seli, Paul; Risko, Evan F; Smilek, Daniel; Schacter, Daniel L

    2016-08-01

    The past decade has seen a surge of research examining mind-wandering, but most of this research has not considered the potential importance of distinguishing between intentional and unintentional mind-wandering. However, a recent series of papers have demonstrated that mind-wandering reported in empirical investigations frequently occurs with and without intention, and, more crucially, that intentional and unintentional mind-wandering are dissociable. This emerging literature suggests that, to increase clarity in the literature, there is a need to reconsider the bulk of the mind-wandering literature with an eye toward deconvolving these two different cognitive experiences. In this review we highlight recent trends in investigations of the intentionality of mind-wandering, and we outline a novel theoretical framework regarding the mechanisms underlying intentional and unintentional mind-wandering.

    1) To evaluate the design of the framework for computerized intention-based clinical practice guidelines; 2) to implement runtime features such as plan recognition and backtracking. To evaluate the design, we implemented the heart failure guideline into GASTINE, a tool for representing and executing intention-based clinical guidelines. Description of the current implementation of intention-based expressions in GASTINE and analysis of some generic shortcomings. Explanation of how these shortcomings are addressed. Presentation of how plan recognition and backtracking work and how they improve the system. The improved guideline system is rather flexible, i.e., it allows deviations from the guideline as long as they are in the spirit of the guideline. The recognition of actions as intended by the users facilitates a flexible decision support system. The intentions are used to explain why certain actions were suggested. Therefore it is assumed that showing the intention behind suggested actions provides a better insight into why these actions are advised.

  16. Third birth intentions and uncertainty in Canada.

    PubMed

    1998-01-01

    Using data from the 1995 Canadian General Society Survey (GSS-95), we study the intention to have a third child among a sample of women and men who have already had two children (N = 505). Our results show that 15 per cent of the respondents intend to have a third child. Nearly 20 per cent of the respondents are uncertain about their fertility intentions. We found that the same factors that predict intentions also predict uncertainty, and that the effects of these predictors are remarkably similar. In particular, intentions and uncertainty generally decline with age, but increase with regular church attendance, remarriage, and being Catholic. Unlike earlier studies, we found that the sex of previous children has virtually no impact on third-birth intentions or uncertainty.

    We investigated whether there is a relationship between burnout and work characteristics and retirement intentions from older workers. Data were taken from a survey held among Dutch older workers (50+) and their spouses (N=2,892). The results show that high workload, heavy physical work, and lack of challenge are related to burnout. No effect, however, was found for competence. Besides the effect of burnout, retirement intentions are related to the level of marital quality. Older workers who report a higher level of marital quality report a stronger intention to retire. Burnout and retirement intentions are related, but appear to be two different processes. While burnout can generally be explained by the work environment, nonwork related factors enhance our understanding of retirement intentions. This study shows that actual retirement is often preceded by feelings of burnout, in particular a mental detachment from work and feelings of exhaustion.

  18. Mind-Wandering With and Without Intention

    The past decade has seen a surge of research examining mind-wandering, but most of this research has not considered the potential importance of distinguishing between intentional and unintentional mind-wandering. However, a recent series of papers has demonstrated that mind-wandering reported in empirical investigations frequently occurs with and without intention, and more critically, that intentional and unintentional mind-wandering are dissociable. This emerging literature suggests that to increase clarity in the literature, there is a need to reconsider the bulk of the mind-wandering literature with an eye toward deconvolving these two different cognitive experiences. In this review, we highlight recent trends in investigations of the intentionality of mind-wandering and outline a novel theoretical framework regarding the mechanisms underlying intentional and unintentional mind-wandering.

  19. Mediator of moderators: temporal stability of intention and the intention-behavior relation.

    Intention certainty, past behavior, self-schema, anticipated regret, and attitudinal versus normative control all have been found to moderate intention-behavior relations. It is argued that moderation occurs because these variables produce "strong" intentions. Stability of intention over time is a key index of intention strength. Consequently, it was hypothesized that temporal stability of intention would mediate moderation by these other moderators. Participants (N = 185) completed questionnaire measures of theory of planned behavior constructs and moderator variables at two time points and subsequently reported their exercise behavior. Findings showed that all of the moderators, including temporal stability, were associated with significant improvements in consistency between intention and behavior. Temporal stability also mediated the effects of the other moderators, supporting the study hypothesis. Copyright 2003 Society for Personality and Social Psychology, Inc.

  20. Modeling Catastrophic Barrier Island Dynamics

    NASA Astrophysics Data System (ADS)

    Whitley, J. W.; McNamara, D.

    2012-12-01

    Barrier islands, thin strips of sand lying parallel to the mainland coastline, along the U.S. Atlantic and Gulf Coasts appear to have maintained their form for thousands of years in the face of rising sea level. The mechanisms that allow barrier islands to remain robust are transport of sediment from the ocean side of barriers to the top and backside during storms, termed island overwash, and the growth and alongshore propagation of tidal deltas near barrier island inlets. Dynamically these processes provide the necessary feedbacks to maintain a barrier island in an attractor that withstands rising sea level within a phase space of barrier island geometrical characteristics. Current barrier island configurations along the Atlantic and Gulf coasts exist among a wide range of storm climate and underlying geologic conditions and therefore the environment that forces overwash and tidal delta dynamics varies considerably. It has been suggested that barrier islands in certain locations such as those between Avon and Buxton (losing 76% of island width since 1852) and Chandeleur islands (losing 85% of its surface area since 2005) along the Atlantic and Gulf coasts, respectively, may be subject to a catastrophic shift in barrier island attractor states - more numerous inlets cutting barriers in some locations and the complete disappearance of barrier islands in other locations. In contrast to common models for barrier islands that neglect storm dynamics and often only consider cross-shore response, we use an alongshore extended model for barrier island dynamics including beach erosion, island overwash and inlet cutting during storms, and beach accretion, tidal delta growth and dune and vegetation growth between storms to explore the response of barrier islands to a wide range of environmental forcing. Results will be presented that show how barrier island attractor states are altered with variations in the rate of sea level rise, storminess, and underlying geology. We will

    The area south of the Queen Charlotte Islands and north of Vancouver Island is characterized by the transition from the Cascadia subduction zone to the Queen Charlotte transform fault zone. The tectonic setting involves the Pacific, North American, Juan de Fuca, and Explorer plates, and the Winona block, as well as the Queen Charlotte and Revere-Dellwood-Wilson faults, Explorer ridge, Nootka fault, and Cascadia subduction zone. On the basis of GPS campaign data from 1993 to 2008 we derive a crustal velocity field for North Vancouver Island and the adjacent mainland. This velocity data is the basis for interpretation of the tectonics of the transition from the convergent to transform boundaries. Our GPS data show significant shear velocities in the Bella Coola region, ~250 km inland from the Queen Charlotte fault, although there is no seismic activity in the area. We use geodynamic models to better understand the discrepancy between the GPS data and the seismic data. We use the GPS velocities to determine whether the measured deformation rates of northernmost Vancouver Island, related to its interaction with the Explorer Plate and possibly the Queen Charlotte transform margin, are transient or permanent. Geodynamic models are used to find out if deformation in the region including North Vancouver Island, Queen Charlotte Islands, and the adjacent mainland (Coast Shear Zone) is transient or long-term. To constrain the model, we use the rheology and structure of the region, with reasonable values for elastic thickness and viscosity. Two end-member models describing how the Pacific/North America plate convergence is accommodated off the Queen Charlotte Islands have been developed by others. They assume either internal crustal shortening or underthrusting of the Pacific plate. With the new GPS data we can further investigate which model explains the tectonic situation more appropriately. An earlier model strongly suggests an underthrusting fault fully locked down to 14

    The growth of Ge on Si(001) is investigated in situ at 500 and 600 deg. C, combining grazing incidence diffraction, multiple wavelength anomalous diffraction, and small angle scattering. This allows probing simultaneously the island shape, strain state, composition, and the transition from wetting layer to island growth. At 500 deg. C no intermixing occurs. The wetting layer is found to decrease by one atomic layer at the onset of island nucleation. At 600 deg. C interdiffusion plays an important role in strain relaxation leading to a more stable wetting layer. Small angle scattering yields the island morphology and shows the transition from pyramids to multifacetted domes.

    Previous research has shown that the degree to which individuals base their intentions on particular underlying cognitions (i.e., motives) significantly moderates the intention-behavior relationship. Studies have individually examined the moderating effect of intentions based on overall attitude, affective attitudes, injunctive norms, and moral norms. The present research used a within-persons approach to simultaneously test the moderating effects of intentions based on instrumental attitude, affective attitude, anticipated affective reactions, injunctive norms, descriptive norms, and moral norms on the intention-behavior relationship and the impact of controlling for intention stability, self-efficacy, and past behavior. Adults (N = 366) completed questionnaires assessing instrumental attitude, affective attitude, anticipated affective reactions, injunctive norms, descriptive norms, moral norms, self-efficacy and past behavior at baseline; intentions at baseline and 1-month follow-up; and behavior at 2-month follow-up for 20 health behaviors. The main outcome measures were the self-reported performance of 20 health behaviors. When tested simultaneously using multilevel modeling the only significant moderator of the intention-behavior relationship was the extent to which intentions were based on anticipated affective reactions (intentions more strongly based on anticipated affective reactions were significantly stronger predictors of behavior). This effect remained when we also controlled for intention stability (which also moderated the intention-behavior relationship), self-efficacy, and past behavior. Intentions based on anticipated affective reactions may be particularly important predictors of health behaviors. Studies manipulating such intentions to test their effects on behavior change are required. (c) 2016 APA, all rights reserved).

    Intentional burns injuries are associated with high mortality rates, and for survivors, high levels of physical and psychological morbidity. This study provides a comprehensive assessment of intentional burn admissions to the adult Burns Unit at Bir Hospital, Kathmandu, Nepal, during the period 2002-2013. A secondary data analysis of de-identified data of patients hospitalized at Bir Hospital, Kathmandu, with a burn during the period of 1 January 2002 to 31 August 2013. Socio-demographic, injury and psychosocial factors of patients with intentional and unintentional burns are described and compared. Chi-square tests, Fisher's exact test and Wilcoxon rank sum tests were used to determine statistical significance. There were a total of 1148 burn admissions of which 329 (29%) were for intentional burn, 293 (26%) were self-inflicted and 36 (3%) were due to assault. Mortality rates for intentional burns were approximately three times those for unintentional burns (60 vs. 22%). When compared to unintentional burns, patients with intentional burns were more likely to be female (79 vs. 48%), married (84 vs. 67%), younger (25 vs. 30 years), have more extensive burns (total body surface area, %: 55 vs. 25) and higher mortality (60 vs. 22%). Intentional burns were more likely to occur at home (95 vs. 67%), be caused by fire (96 vs. 77%), and kerosene was the most common accelerant (91 vs. 31%). A primary psychosocial risk factor was identified in the majority of intentional burn cases, with 60% experiencing adjustment problems/interpersonal conflict and 32% with evidence of a pre-existing psychological condition. A record of alcohol/substance abuse related to the patient or other was associated with a greater proportion of intentional burns when compared with unintentional burns (17 vs. 4%). The majority of intentional burn patients were female. Almost all intentional burns occurred in the home and were caused by fire, with kerosene the most common accelerant used. Underlying

    Background Low-income and racial/ethnic minority populations experience disproportionate colorectal cancer (CRC) burden and poorer survival. Novel behavioral strategies are needed to improve screening rates in these groups. Purpose To test a theoretically based “implementation intentions” intervention for improving CRC screening among unscreened adults in urban safety-net clinics. Design Randomized controlled trial. Setting/participants Adults (N=470) aged ≥50 years, due for CRC screening, from urban safety-net clinics were recruited. Intervention The intervention (conducted in 2009–2011) was delivered via touchscreen computers that tailored informational messages to decisional stage and screening barriers. The computer then randomized participants to generic health information on diet and exercise (Comparison group) or “implementation intentions” questions and planning (Experimental group) specific to the CRC screening test chosen (fecal immunochemical test or colonoscopy). Main outcome measures The primary study outcome was completion of CRC screening at 26 weeks based on test reports (analysis conducted in 2012–2013). Results The study population had a mean age of 57 years, and was 42% non-Hispanic African American, 28% non-Hispanic white, and 27% Hispanic. Those receiving the implementation intentions–based intervention had higher odds (AOR=1.83, 95% CI=1.23, 2.73) of completing CRC screening than the Comparison group. Those with higher self-efficacy for screening (AOR=1.57, 95% CI=1.03, 2.39), history of asthma (AOR=2.20, 95% CI=1.26, 3.84), no history of diabetes (AOR=1.86, 95% CI=1.21, 2.86), and reporting they had never heard that “cutting on cancer” makes it spread (AOR=1.78, 95% CI=1.16, 2.72) were more likely to complete CRC screening. Conclusions The results of this study suggest that programs incorporating an implementation intentions approach can contribute to successful completion of CRC screening even among very low-income and

    The symmetry-breaking phase transitions of the universe and of superfluid (3)He may lead to the formation of different states with different order parameters. In both cases the energy potential below the transition temperature has a complicated multidimensional profile with many local minima and saddle points, which correspond to different states. Consequently, not only topological defects, but also islands of different metastable states can be created. Using (3)He we can analyse the properties and experimental consequences of such transitions and, in particular, the first-order phase transition between the two low symmetry states.

    Individuals make choices in, and adjust to, a world of work that is often a moving target. Because work is so central to human functioning, and transitions in and out of work can have major mental health repercussions, the authors argue that applied psychologists in health services need to understand those transitions. This article focuses on the different types of transition throughout a person's working life and the resources needed at different stages to ensure the success of these transitions. The authors start by examining the roles of capability and adaptability in supporting and facilitating adjustment to work transitions and their relation to identity development. They then examine the role of social and institutional contexts in shaping work transitions and their outcomes. The authors focus on voluntary versus involuntary transitions and then broaden the lens in discussing the policy implications of research on work transitions.

    Heron Island is located at the sourthern end of Australia's 2,050 km-long Great Barrier Reef. Surrounded by coral reef and home to over 1000 species of fish, scuba divers and scientists alike are drawn to the island's resort and research station. The true-color image above was taken by Space Imaging's Ikonos satellite with a resolution of 4 meters per pixel-high enough to see individual boats tied up at the small marina. The narrow channel leading from the marina to the ocean was blasted and dredged decades ago, before the island became a national park. Since then the Australian government has implemented conservation measures, such as limiting the number of tourists and removing or recycling, instead of incinerating, all trash. One of the applications of remote sensing data from Ikonos is environmental monitoring, including studies of coral reef health. For more information about the island, read Heron Island.

    We used teleseismic receiver functions to map the seismic structure under the Samoan Islands in the southern Pacific Ocean. We acquired seismograms for the permanent seismic station, AFI, and for five temporary stations located across the island chain from the Samoan Lithospheric Integrated Seismic Experiment (SLISE). We used multiple-taper correlation and Markov chain Monte Carlo algorithms to calculate receiver functions for events with epicentral distance of 30° to 95° and examined the results in a frequency range of 1.0 - 5.0 Hz for crustal structure and 0.1 - 2.0 Hz for mantle structure. We identify complex crustal layering, including the interface between volcanic rocks and the ocean crust and a substantial underplated layer beneath the normal ocean crust. We find that the crust thins with decreasing age across the Samoan Islands and correlates with previous observations from gravity data (Workman, 2005). We additionally identify a velocity increase in the range of 50-100 km depth, potentially the Hales discontinuity. Deeper in the mantle, we observe transition zone thickness of 245-250 km across the island chain, which is within the margin of error for globally observed transition zone thickness. When migrated with IASP, transition zone discontinuity depths do appear deeper beneath the youngest island, indicating slower velocities and/or deeper discontinuity depths relative to the older islands in the system. We will provide improved constraints on transition zone discontinuity depths from ScS reverberations for all stations, and will place the crust and mantle results into a multi-disciplinary context, with comparisons to geochemical and surface observations.

    2014-01-01

    As sea level rises and hurricanes become more intense, barrier islands around the world become increasingly vulnerable to conversion from self-sustaining migrating landforms to submerging or subaqueous sand bodies. To explore the mechanism by which such state changes occur and to assess the factors leading to island disintegration, we develop a suite of numerical simulations for the Chandeleur Islands in Louisiana, U.S.A., which appear to be on the verge of this transition. Our results suggest that the Chandeleurs are likely poised to change state, leading to their demise, within decades depending on future storm history. Contributing factors include high rates of relative sea level rise, limited sediment supply, muddy substrate, current island position relative to former Mississippi River distributary channels, and the effects of changes in island morphology on sediment transport pathways. Although deltaic barrier islands are most sensitive to disintegration because of their muddy substrate, the importance of relative sea level rise rate in determining the timing of threshold crossing suggests that the conceptual models for deltaic barrier island formation and disintegration may apply more broadly in the future.

    Objective. The objective of this work was to quantitatively investigate the mechanisms underlying the performance gains of the recently reported ‘recalibrated feedback intention-trained Kalman Filter’ (ReFIT-KF). Approach. This was accomplished by designing variants of the ReFIT-KF algorithm and evaluating training and online data to understand the neural basis of this improvement. We focused on assessing the contribution of two training set innovations of the ReFIT-KF algorithm: intention estimation and the two-stage training paradigm. Main results. Within the two-stage training paradigm, we found that intention estimation independently increased target acquisition rates by 37% and 59%, respectively, across two monkeys implanted with multiunit intracortical arrays. Intention estimation improved performance by enhancing the tuning properties and the mutual information between the kinematic and neural training data. Furthermore, intention estimation led to fewer shifts in channel tuning between the training set and online control, suggesting that less adaptation was required during online control. Retraining the decoder with online BMI training data also reduced shifts in tuning, suggesting a benefit of training a decoder in the same behavioral context; however, retraining also led to slower online decode velocities. Finally, we demonstrated that one- and two-stage training paradigms performed comparably when intention estimation is applied. Significance. These findings highlight the utility of intention estimation in reducing the need for adaptive strategies and improving the online performance of BMIs, helping to guide future BMI design decisions.

    Locomotion intent prediction is essential for the control of powered lower-limb prostheses to realize smooth locomotion transitions. In this research, we develop a multi-sensor fusion based locomotion intent prediction system, which can recognize current locomotion mode and detect locomotion transitions in advance. Seven able-bodied subjects were recruited for this research. Signals from two foot pressure insoles and three inertial measurement units (one on the thigh, one on the shank and the other on the foot) are measured. A two-level recognition strategy is used for the recognition with linear discriminate classifier. Six kinds of locomotion modes and ten kinds of locomotion transitions are tested in this study. Recognition accuracy during steady locomotion periods (i.e., no locomotion transitions) is 99.71% ± 0.05% for seven able-bodied subjects. During locomotion transition periods, all the transitions are correctly detected and most of them can be detected before transiting to new locomotion modes. No significant deterioration in recognition performance is observed in the following five hours after the system is trained, and small number of experiment trials are required to train reliable classifiers.

    The promotion of home cooking is a strategy used to improve diet quality and health. However, modern home cooking typically includes the use of processed food which can lead to negative outcomes including weight gain. In addition, interventions to improve cooking skills do not always explain how theory informed their design and implementation. The Behaviour Change Technique (BCT) taxonomy successfully employed in other areas has identified essential elements for interventions. This study investigated the effectiveness of different instructional modes for learning to cook a meal, designed using an accumulating number of BCTs, on participant's perceived difficulty, enjoyment, confidence and intention to cook from basic ingredients. 141 mothers aged between 20 and 39 years from the island of Ireland were randomised to one of four conditions based on BCTs (1) recipe card only [control condition]; (2) recipe card plus video modelling; (3) recipe card plus video prompting; (4) recipe card plus video elements. Participants rated their enjoyment, perceived difficulty, confidence and intention to cook again pre, mid and post experiment. Repeated one-way factorial ANOVAs, correlations and a hierarchical regression model were conducted. Despite no significant differences between the different conditions, there was a significant increase in enjoyment (P < 0.001), confidence (P < 0.001) and intention to cook from basics again (P < 0.001) and a decrease in perceived difficulty (P = 0.001) after the experiment in all conditions. Intention to cook from basics pre-experiment, and confidence and enjoyment (both pre and post experiment) significantly contributed to the final regression model explaining 42% of the variance in intention to cook from basics again. Cooking interventions should focus on practical cooking and increasing participants' enjoyment and confidence during cooking to increase intention to cook from basic ingredients at home.

  17. Geohydrology of Enewetak Atoll islands and reefs

    Buddemeier, R.W.

    1981-05-06

    Extensive tidal studies in island wells and the lagoon at Enewetak Atoll have shown that island ground water dynamics are controlled by a layered aquifer system. The surface aquifer of unconsolidated Holocene material extends to a depth of approximately 15 m, and has a hydraulic conductivity K = 60 m/day. From 15 to 60 m (approximate lagoon depth) the reef structure consists of successive layers of altered Pleistocene materials, with bulk permeability substantially higher than that of the surface aquifer. Because of wave set-up over the windward reef and the limited pass area for outflow at the south end of the atoll, lagoon tides rise in phase with the ocean tides but fall later than the ocean water level. This results in a net lagoon-to-ocean head which can act as the driving force for outflow through the permeable Pleistocene aquifer. This model suggests that fresh water, nutrients or radioactive contaminants found in island ground water or reef interstitial water may be discharged primarily into the ocean rather than the lagoon. Atoll island fresh water resources are controlled by recharge, seawater dilution due to vertical tidal mixing between the surface and deeper aquifers, and by loss due to entrainment by the outflowing water in the deeper aquifers. Estimated lagoon-ot-ocean transit times through the deep aquifer are on the order of a few years, which corresponds well to the freshwater residence time estimates based on inventory and recharge. Islands in close proximity to reef channels have more fresh ground water than others, which is consistent with a locally reduced hydraulic gradient and slower flow through the Pleistocene aquifers.

The island is underlain by sedimentary rocks, cut by still-active faults. The streams follow a dendritic drainage system: there are many contributing streams (analogous to the twigs of a tree), which are then joined together into the tributaries of the main river (the branches and the trunk of the tree, respectively). They develop where the river channel follows the slope of the terrain.

    2004-01-01

    Restoration of natural habitat has become increasingly important over the last three decades in the United States, first as mitigation for development (especially in wetlands), and more recently in natural areas. This latter restoration has come about as land managing agencies have seen the need to reverse the impact of past land uses and agencies like the National Park Service have taken on the responsibility for less-than-pristine lands. Restorations have typically been carried out with little prior study and with no follow-up monitoring. On the Channel Islands, the need for restoration is great, but the desire is to base this restoration on sound ecological understanding. By conducting surveys, implementing long-term research and monitoring, and by conducting population and community dynamics research, the necessary data is obtained to arrive at such an understanding. Once management actions have been taken to effect restoration, monitoring is used to determine the success of those actions. The intention is to gain enough of an understanding of the islands' ecosystems that we can manage to restore, not just populations of native plants and animals, but also the processes of a naturally functioning ecosystem. ??

    In this paper, the growth mechanism and the morphologies of GaSb islands grown on Si (1 0 0) by low-pressure metal-organic chemical vapor deposition have been studied. It was observed the GaSb growth mode transited from SK to VW mode with time, while the islands migrated in VW mode on the surface. As growth time prolonging, the islands were coarsening consistent with the considerations of Ostwald ripening substituting for migration. And it was the similar coalescence process in the various interruption time. The formation of giant islands reduced the surface energy with the island-induced strain fields which drive the islands distribution evenly.

  4. Archaeoastronomy of Easter Island

    NASA Astrophysics Data System (ADS)

    Edwards, Edmundo

    Astronomer priests or "skywatchers" on Easter Island lived in stone towers that were used as observatories and built stone markers in the periphery that indicated the heliacal rising of certain stars that served to indicate the arrival of marine birds, turtles, the offshore fishing season, and times for planting and harvest. Petroglyphs related to such sites depict outriggers, fishhooks, pelagic fish, and turtles and supposedly represented a star map. In this chapter, we analyze a set of such skywatchers dwellings, and stone markers located upon the North coast of Easter Island that have astronomic orientations, its related petroglyphs, and the relations between these directions with their yearly activities and their ritual calendar.

    The Long Island Solar Farm (LISF) is a remarkable success story, whereby very different interest groups found a way to capitalize on unusual circumstances to develop a mutually beneficial source of renewable energy. The uniqueness of the circumstances that were necessary to develop the Long Island Solar Farm make it very difficult to replicate. The project is, however, an unparalleled resource for solar energy research, which will greatly inform large-scale PV solar development in the East. Lastly, the LISF is a superb model for the process by which the project developed and the innovation and leadership shown by the different players.

    The Canarian Archipelago is an oceanic island volcanic chain with a long-standing history of volcanic activity (> 40 Ma). It is located off the NW coast of the African continent, lying over a transitional crust of the Atlantic African passive margin. At least 12 eruptions have been occurred on the islands of Lanzarote, Tenerife and La Palma in the last 500 years. Volcanism manifest predominantly as basaltic strombolian monogenetic activity (whole archipelago) and central felsic volcanism (active only in Tenerife Island). We concentrate our studies in the two most active islands, Tenerife and La Palma. In these islands, we tested different methodologies of geodetic monitoring systems. We use a combination of ground- and space-based techniques. At Tenerife Island, a differential interferometric study was performed to detect areas of deformation. DInSAR detected two clear areas of deformation, using this results a survey-based GPS network was designed and optimized to control those deformations and the rest of the island. Finally, using SBAS DInSAR results weak spatial long- wavelength subsidence signals has been detected. At La Palma, the first DInSAR analysis have not shown any clear deformation, so a first time series analysis was performed detecting a clear subsidence signal at Teneguia volcano, as for Tenerife a GPS network was designed and optimized taking into account stable and deforming areas. After several years of activities, geodetic results served to study ground deformations caused by a wide variety of sources, such as changes in groundwater levels, volcanic activity, volcano-tectonics, gravitational loading, etc. These results proof that a combination of ground-based and space-based techniques is suitable tool for geodetic volcano monitoring in Canary Islands. Finally, we would like to strength that those results could have serious implications on the continuous geodetic monitoring system design and implementation for the Canary Islands which is under

    Teeth from 38 aboriginal remains of La Palma (Canary Islands) were analyzed for external and endogenous mitochondrial DNA control region sequences and for diagnostic coding positions. Informative sequences were obtained from 30 individuals (78.9%). The majority of lineages (93%) were from West Eurasian origin, being the rest (7%) from sub-Saharan African ascription. The bulk of the aboriginal haplotypes had exact matches in North Africa (70%). However, the indigenous Canarian sub-type U6b1, also detected in La Palma, has not yet been found in North Africa, the cradle of the U6 expansion. The most abundant H1 clade in La Palma, defined by transition 16260, is also very rare in North Africa. This means that the exact region from which the ancestors of the Canarian aborigines came has not yet been sampled or that they have been replaced by later human migrations. The high gene diversity found in La Palma (95.2±2.3), which is one of the farthest islands from the African continent, is of the same level than the previously found in the central island of Tenerife (92.4±2.8). This is against the supposition that the islands were colonized from the continent by island hopping and posterior isolation. On the other hand, the great similarity found between the aboriginal populations of La Palma and Tenerife is against the idea of an island-by-island independent maritime colonization without secondary contacts. Our data better fit to an island model with frequent migrations between islands. PMID:19337312

    Human intentional communication is marked by its flexibility and context sensitivity. Hypothesized brain mechanisms can provide convincing and complete explanations of the human capacity for intentional communication only insofar as they can match the computational power required for displaying that capacity. It is thus of importance for cognitive neuroscience to know how computationally complex intentional communication actually is. Though the subject of considerable debate, the computational complexity of communication remains so far unknown. In this paper we defend the position that the computational complexity of communication is not a constant, as some views of communication seem to hold, but rather a function of situational factors. We present a methodology for studying and characterizing the computational complexity of communication under different situational constraints. We illustrate our methodology for a model of the problems solved by receivers and senders during a communicative exchange. This approach opens the way to a principled identification of putative model parameters that control cognitive processes supporting intentional communication. PMID:21747765

    Domestic goats, Capra hircus, were intentionally introduced to numerous oceanic islands beginning in the sixteenth century. The remarkable ability of C. hircus to survive in a variety of conditions has enabled this animal to become feral and impact native ecosystems on islands throughout the world. Direct ecological impacts include consumption and trampling of native plants, leading to plant community modification and transformation of ecosystem structure. While the negative impacts of feral goats are well-known and effective management strategies have been developed to control this invasive species, large populations persist on many islands. This review summarizes the impacts of feral goats on Pacific island ecosystems, and the management strategies available to control this invasive species.

    While recently there have been renewed interest in women's childbearing intentions, the authors sought to bring needed research attention to understanding men's childbearing intentions. Nationally representative data from the 2006-2010 National Survey of Family Growth (NSFG) was used to examine pregnancy intentions and happiness for all births reported by men in the 5 years preceding the interview. We used bivariate statistical tests of associations between intention status, happiness about the pregnancy, and fathers' demographic characteristics, including joint race/ethnicity and union status subgroups. Multivariate logistic regressions were used to calculate adjusted odds ratios of a birth being intended, estimated separately by father's union status at birth. Using comparable data and measures from the male and female NSFG surveys, we tested for gender differences intentions and happiness, and examined the sensitivity of our results to potential underreporting of births by men. Nearly four out of ten of births to men were reported as unintended, with significant variation by men's demographic traits. Non-marital childbearing was more likely to be intended among Hispanic and black men. Sixty-two percent of births received a 10 on the happiness scale. Happiness about the pregnancy varied significantly by intention status. Men were significantly happier than women about the pregnancies, with no significant difference in intention status. Potential underreporting of births by men had little impact on these patterns. This study brings needed focus to men's childbearing intentions and improves our understanding of the context of their role as fathers. Men need to be included in strategies to prevent unintended pregnancy.

  18. Christmas Island birds returning

    NASA Astrophysics Data System (ADS)

    Six months after their mass exodus, birds are beginning to return to Christmas Island. Roughly 17 million birds, almost the entire adult bird population, either perished or fled their mid-Pacific atoll home last autumn, leaving behind thousands of nestlings to starve (Eos, April 5, 1983, p. 131). It is believed that the strong El Niño altered the ecology of the surrounding waters and forced the birds to flee. Christmas Island is the world's largest coral atoll.“Ocean and atmosphere scientists are unsure of future directions for the El Niño conditions and cannot now predict what will happen to the birds in the coming months,” said Ralph W. Schreiber, curator of ornithology at the Natural History Museum of Los Angeles County in California. Heisthe ornithologist who discovered the disappearance. “The recovery of the bird populations depends on the food supply in the waters surrounding the island.” The island's birds feed exclusively on small fish and squid.

  6. Multidecadal shoreline changes of atoll islands in the Marshall Islands

    NASA Astrophysics Data System (ADS)

    2012-12-01

    Atoll islands are considered highly vulnerable to the impacts of continued sea level rise. One of the most commonly predicted outcomes of continued sea level rise is widespread and chronic shoreline erosion. Despite the widespread implications of predicted erosion, the decadal scale changes of atoll island shorelines are poorly resolved. The Marshall Islands is one of only four countries where the majority of inhabited land is comprised of reef and atoll islands. Consisting of 29 atolls and 5 mid-ocean reef islands, the Marshall Islands are considered highly vulnerable to the impacts of sea level rise. A detailed analysis of shoreline change on over 300 islands on 10 atolls was undertaken using historic aerial photos (1945-1978) and modern high resolution satellite imagery (2004-2012). Results highlight the complex and dynamic nature of atoll islands, with significant shifts in shoreline position observed over the period of analysis. Results suggest shoreline accretion is the dominant mode of change on the islands studied, often associated with a net increase in vegetated island area. However, considerable inter- and intra-atoll variability exists with regards to shoreline stability. Findings are discussed with respect to island morphodynamics and potential hazard mitigation and planning responses within atoll settings.

    Demand for primary care services is rising. Nurse practitioners (NPs) serve vital roles in meeting primary care demands. Workforce planning requires understanding NP retirement intentions. This study examines factors that relate to NPs, aged 55 years and older, and their intent to retire within 5 years. We used the 2012 National Sample Survey of Nurse Practitioners to examine the relationship between NP demographic characteristics (gender, race/ethnicity, marital status, nursing degree), work environment characteristics (part-time vs. full-time status, primary or specialty care, earnings, job satisfaction), and intent to retire. Descriptive, bivariate, and multivariate analyses were conducted. A total of 3171 working NPs, 55 years of age and older, were included. Fifty-nine percent of NPs 60 years and older and 15% of NPs 55-59 intend to retire in the next 5 years. Working part-time and having less than a master's degree were associated with intent to retire. Being "very satisfied" with one's job was related to lower odds of intent to retire versus being "satisfied." Being "dissatisfied" with one's job and working in primary care were related to intending to retire for the NPs 55-59. Given the relationship between higher job satisfaction and lower intent to retire, efforts to increase NPs' job satisfaction may result in less early retirement. ©2016 American Association of Nurse Practitioners.

  8. Context-Aware Online Commercial Intention Detection

    NASA Astrophysics Data System (ADS)

    Hu, Derek Hao; Shen, Dou; Sun, Jian-Tao; Yang, Qiang; Chen, Zheng

    With more and more commercial activities moving onto the Internet, people tend to purchase what they need through Internet or conduct some online research before the actual transactions happen. For many Web users, their online commercial activities start from submitting a search query to search engines. Just like the common Web search queries, the queries with commercial intention are usually very short. Recognizing the queries with commercial intention against the common queries will help search engines provide proper search results and advertisements, help Web users obtain the right information they desire and help the advertisers benefit from the potential transactions. However, the intentions behind a query vary a lot for users with different background and interest. The intentions can even be different for the same user, when the query is issued in different contexts. In this paper, we present a new algorithm framework based on skip-chain conditional random field (SCCRF) for automatically classifying Web queries according to context-based online commercial intention. We analyze our algorithm performance both theoretically and empirically. Extensive experiments on several real search engine log datasets show that our algorithm can improve more than 10% on F1 score than previous algorithms on commercial intention detection.

    When a magnetic island is embedded in toroidally symmetric tokamaks, the toroidal symmetry in |B| is broken [K. C. Shaing, Phys. Rev. Lett. 87, 245003 (2001)]. Here, B is the magnetic field. This broken symmetry induces an additional bootstrap current density in the vicinity of the island. It is illustrated that this island induced bootstrap current density modifies the island evolution equation and imposes a lower limit on the absolute value of the tearing mode stability parameter {delta}{sup '} for the island to be unstable. This lower limit depends on the local poloidal plasma beta {beta}{sub p}, the ratio of the plasma pressure to the poloidal magnetic field pressure. If {beta}{sub p} is high enough, the magnetic island is stable. This mechanism provides an alternative route to stabilize the island.

    2012-01-01

    Although forming implementation intentions (Gollwitzer, 1999) has been demonstrated to generally improve prospective memory, the underlying cognitive mechanisms are not completely understood. It has been proposed that implementation-intention encoding encourages spontaneous retrieval (McDaniel & Scullin, 2010). Alternatively one could assume the positive effect of implementation-intention encoding is caused by increased or more efficient monitoring for target cues. To test these alternative explanations and to further investigate the cognitive mechanisms underlying implementation-intention benefits, in two experiments participants formed the intention to respond to specific target cues in a lexical decision task with a special key, but then had to suspend this intention during an intervening word-categorisation task. Response times on trials directly following the occurrence of target cues in the intervening task were significantly slower with implementation-intention encoding than with standard encoding, indicating that spontaneous retrieval was increased (Experiment 1). However, when activation of the target cues was controlled for, similar slowing was found with both standard and implementation-intention encoding (Experiment 2). The results imply that implementation-intention encoding as well as increased target-cue activation foster spontaneous retrieval processes.

    The rate of thermal transitions in a kagome spin ice element is calculated using harmonic transition state theory for magnetic systems. Each element consists of six prolate magnetic islands. Minimum energy paths on the multidimensional energy surface are found to estimate activation energy. Vibrational frequencies are also calculated to estimate the rate of the various transitions. An overall transition rate between equivalent ground states is calculated by using the stationary state approximation including all possible transition paths. The resulting transition rate is in a good agreement with experimentally measured lifetime.

  16. Analysis of using EMG and mechanical sensors to enhance intent recognition in powered lower limb prostheses

    2014-10-01

    Objective. The purpose of this study was to determine the contribution of electromyography (EMG) data, in combination with a diverse array of mechanical sensors, to locomotion mode intent recognition in transfemoral amputees using powered prostheses. Additionally, we determined the effect of adding time history information using a dynamic Bayesian network (DBN) for both the mechanical and EMG sensors. Approach. EMG signals from the residual limbs of amputees have been proposed to enhance pattern recognition-based intent recognition systems for powered lower limb prostheses, but mechanical sensors on the prosthesis—such as inertial measurement units, position and velocity sensors, and load cells—may be just as useful. EMG and mechanical sensor data were collected from 8 transfemoral amputees using a powered knee/ankle prosthesis over basic locomotion modes such as walking, slopes and stairs. An offline study was conducted to determine the benefit of different sensor sets for predicting intent. Main results. EMG information was not as accurate alone as mechanical sensor information (p < 0.05) for any classification strategy. However, EMG in combination with the mechanical sensor data did significantly reduce intent recognition errors (p < 0.05) both for transitions between locomotion modes and steady-state locomotion. The sensor time history (DBN) classifier significantly reduced error rates compared to a linear discriminant classifier for steady-state steps, without increasing the transitional error, for both EMG and mechanical sensors. Combining EMG and mechanical sensor data with sensor time history reduced the average transitional error from 18.4% to 12.2% and the average steady-state error from 3.8% to 1.0% when classifying level-ground walking, ramps, and stairs in eight transfemoral amputee subjects. Significance. These results suggest that a neural interface in combination with time history methods for locomotion mode classification can enhance intent

    Powered lower limb prostheses, capable of multiple locomotion modes, are being developed for transfemoral amputees. Current devices do not seamlessly transition between modes such as level walking, stairs and slopes. The purpose of this study was to develop an intent recognition system and test its performance across five different modes. A Dynamic Bayesian Network (DBN) was used for classification of neural and mechanical signals while four amputees completed a circuit containing level-walking, ramp ascent, ramp descent, stair ascent and stair descent. Our results indicate that transitional and steady-state stair steps had a high recognition rate (>99%), while ramp steps were significantly more difficult to classify (p<0.01) (13.7% error on transition steps and 1.3% on steady-state steps). With all five modes trained into the same system, the transitional error rate was 11.3%. Transitional error could be reduced by 31% by training the ramp ascent mode as level walking, and 92% by training both ramp ascent and descent as level walking. This is a viable solution when the level-walking mode can accommodate ramp modes which is currently the case with the ramp ascent. The high recognition rates for recognizing stairs shown in this study demonstrates the potential for an intent recognition system using neural information to allow amputees to naturally transition between locomotion modes on powered prostheses.

    The study examined the impact of precollege drinking intentions on college heavy episodic drinking (HED) in a sample of women making the transition from high school to college. We hypothesized that the effects of drinking intentions on college first and second semester HED would be mediated by first semester social norms and drinking pressure. High school seniors (n = 416) recruited from the community were assessed at the time of high school graduation and at the end of the first and second semesters of college. The hypothesized model was supported. After controlling for high school HED, precollege drinking intentions predicted first semester descriptive and injunctive social norms and social pressure to drink. Social influence variables were associated with higher frequency HED in the first semester, which in turn predicted higher frequency HED in the second semester. Results suggest that precollege drinking intentions, independent of high school HED, may influence selection of college social environments and play a significant role in actual college HED. Assessment and targeting of these intentions may aid in prevention of college HED.

    Internationally pre-registration education programs have ranged from entirely specialist to entirely generalist with varying degrees of specialty preparation in between. Students in generalist programs with specialty practice options may benefit from novel pedagogical approaches, such as intentional learning, to ease the transition from generalist to specialist practice. The purpose of this qualitative descriptive study was to understand undergraduate students' experiences of intentional learning in a 4-week consolidated cardiac specialty practicum. Eight students (7 females, 1 male) participated in a combination of weekly Blackboard discussions and an end-of-practicum focus group and completed a competency self-rating. Students had marred expectations about the integration of intentional learning in their specialty practice experience. They reflected advantages and disadvantages of both intentional and total patient care learning models but worked with their instructor to find the right balance that maximized learning. Students identified features that maximized intentional learning including open-ended questions, using learning versus workspaces, receiving feedback, and integrating peer interaction. Despite advancing their confidence and competence in specialty practice students remained anxious about their ability to assume the role of the graduate nurse in a years' time. Preparing a generalist nurse for the workforce needs to be balanced with meeting students' needs and increasing professional demands for specialty experiences in undergraduate nurse education programs.

  2. Islands Containing Slowly Hydrolyzable GTP Analogs Promote Microtubule Rescues

    2012-01-01

    Microtubules are dynamic polymers of GTP- and GDP-tubulin that undergo stochastic transitions between growing and shrinking phases. Rescues, the conversion from shrinking to growing, have recently been proposed to be to the result of regrowth at GTP-tubulin islands within the lattice of growing microtubules. By introducing mixed GTP/GDP/GMPCPP (GXP) regions within the lattice of dynamic microtubules, we reconstituted GXP islands in vitro (GMPCPP is the slowly hydrolyzable GTP analog guanosine-5′-[(α,β)-methyleno]triphosphate). We found that such islands could reproducibly induce rescues and that the probability of rescue correlated with both the size of the island and the percentage of GMPCPP-tubulin within the island. The islands slowed the depolymerization rate of shortening microtubules and promoted regrowth more readily than GMPCPP seeds. Together, these findings provide new mechanistic insights supporting the possibility that rescues could be triggered by enriched GTP-tubulin regions and present a new tool for studying such rescue events in vitro.

    Easter Island is a small island of 180 km2, located 3,800 km from the Chilean coast and one of the most isolated inhabited places in the world. Since the mid-twentieth century, it has been undergoing an epidemiological transition in relation to the causes of death, from a predominance of infectious to non-communicable diseases (NCDs) such as cardiovascular ailments and cancer. The aim of this study is to describe the causes of death to Easter Island between 2000 and 2012, so the statistical records of Hanga Roa Hospital and death certificates were reviewed. The period under review of 13 years there was a total of 252 deaths, an average to 19.3 deaths per year. The most frequent causes of death found in the general population of Easter Island were cardiovascular diseases (25.4%), followed by neoplasms (23.4%), accidents (18.6%). Related to Rapa Nui people, cardiovascular and neoplastic diseases (both 26.7%) predominate, while in the population without belonging to the ethnic group the main causes were traumatic (25%) and cardiovascular (22.2%). Comparing the leading causes of death of Easter Island with mainland Chile, it can be seen how they resemble. Taking the island death profile, it is necessary to work on public health strategies aimed to this, considering that some of the causes are completely preventable.

    During the fall of 2005, we interviewed a sample of 103 young men aged 18 to 21 imprisoned at a young offender's prison in England. Drawing on the theory of planned behavior, as well as the theory of cognitive transformation, our purpose was to investigate prisoners' reports of their likelihood of reoffending following release from prison. Primary explanatory factors included measures of attitudes, behavioral control, and subjective norms. Attitudes measured inmates' plans of what they would do following release. Behavioral control variables included indicators of life control and self-efficacy. Subjective norms measured the number of peers inmates reported ever being imprisoned. Prison activities and background characteristics were also modeled. The data were analyzed using regression techniques and structural equation modeling. Intentions to stay out of trouble were most strongly associated with self-efficacy and the number of imprisoned friends reported. Intentions were also associated with the specificity of postrelease plans and life control. Offenders' feelings of life control were stronger among those who had more frequent contact with family members and friends while in prison. Employment prior to prison and family relationships were predictive of contacts with family and friends in prison. Specific policies consistent with our findings include encouragement of contact with family members and friends. In addition, interventions that help offenders make specific plans and increase feelings of control and self-efficacy have promise in helping released offenders successfully complete the transition from prison to the community.

    To examine the self-reported pregnancy intentions of the male partners of expectant adolescent mothers, the accuracy of adolescent mothers' perceptions of their partner's pregnancy intentions, and the concordance between young mothers' and fathers' pregnancy intentions. This cross-sectional pilot study collected interview data from expectant adolescent mothers and their male partners. Data were collected in participants' homes. 35 expectant couples were interviewed separately. Most participants were African American (89% of mothers, 74% of fathers). 69% of mothers were 17-18 years old, and half of the fathers were ≥19. Parents responded to survey questions adapted from the Center for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System Questionnaire. 44% of fathers reported wanting their partner to get pregnant. Another 15% were ambivalent. A kappa statistic of 0.12 (P = .33) indicated very little "accuracy" of mothers' perceptions of their partners' pregnancy intentions. Further, there was low concordance between the pregnancy intentions of mothers and fathers. Young fathers who wanted or were ambivalent about pregnancy were significantly more likely to use no contraception or withdrawal. For a notable number of minority couples, adolescent mothers do not have an accurate perception of their partners' pregnancy intentions and use contraceptive methods that are not within their control. These findings indicate that teen pregnancy prevention interventions must target young males in addition to females and sexually active adolescents should be encouraged to discuss pregnancy intentions with each other.

    2007-01-01

    A double-blind, randomized, placebo-controlled experiment investigated whether chocolate exposed to "good intentions" would enhance mood more than unexposed chocolate. Individuals were assigned to one of four groups and asked to record their mood each day for a week by using the Profile of Mood States. For days three, four and five, each person consumed a half ounce of dark chocolate twice a day at prescribed times. Three groups blindly received chocolate that had been intentionally treated by three different techniques. The intention in each case was that people who ate the chocolate would experience an enhanced sense of energy, vigor, and well-being. The fourth group blindly received untreated chocolate as a placebo control. The hypothesis was that mood reported during the three days of eating chocolate would improve more in the intentional groups than in the control group. Stratified random sampling was used to distribute 62 participants among the four groups, matched for age, gender, and amount of chocolate consumed on average per week. Most participants lived in the same geographic region to reduce mood variations due to changes in weather, and the experiment was conducted during one week to reduce effects of current events on mood fluctuations. On the third day of eating chocolate, mood had improved significantly more in the intention conditions than in the control condition (P = .04). Analysis of a planned subset of individuals who habitually consumed less than the grand mean of 3.2 ounces of chocolate per week showed a stronger improvement in mood (P = .0001). Primary contributors to the mood changes were the factors of declining fatigue (P = .01) and increasing vigor (P = .002). All three intentional techniques contributed to the observed results. The mood-elevating properties of chocolate can be enhanced with intention.

    Santa Rosa Island (SRI) is the second-largest of the California Channel Islands. It is one of 4 east–west aligned islands forming the northern Channel Islands chain, and one of the 5 islands in Channel Islands National Park. The landforms, and collections of landforms called landscapes, of Santa Rosa Island have been created by tectonic uplift and faulting, rising and falling sea level, landslides, erosion and deposition, floods, and droughts. Landscape features, and areas delineating groups of related features on Santa Rosa Island, are mapped, classified, and described in this paper. Notable landscapes on the island include beaches, coastal plains formed on marine terraces, sand dunes, and sand sheets. In this study, the inland physiography has been classified into 4 areas based on relief and degree of fluvial dissection. Most of the larger streams on the island occupy broad valleys that have been filled with alluvium and later incised to form steep- to vertical-walled arroyos, or barrancas, leaving a relict floodplain above the present channel. A better understanding of the processes and mechanisms that created these landscapes enhances visitors’ enjoyment of their surroundings and contributes to improving land and resource management strategies in order to optimize and balance the multiple goals of conservation, preservation, restoration, and visitor experience.

    Raman studies are reported of vanadium dioxide grown on sapphire substrates with morphology ranging from island to continuous layer. Temperatures corresponding to the onset of the structural phase transition and the insulator to metal transition are estimated based on the shifts and disappearance of the phonons, respectively. Minimum dimension h, corresponding to island height or layer thickness, plays a critical role in the transformation. The transition temperature and width exhibit 1/h dependence consistent with finite-size effects related to martensitic nucleation. The length scale below which the finite size effects are important is found to be ˜300 nm.

    With growing awareness that sustainable consumption is important for quality of life on earth, many individuals intend to act more sustainably. In this regard, interest in reducing meat consumption is on the rise. However, people often do not translate intentions into actual behavior change. To address this intention-behavior gap, we tested the self-regulation strategy of mental contrasting with implementation intentions (MCII). Here, people identify and imagine a desired future and current obstacles standing in its way. They address the obstacles with if-then plans specifying when, where, and how to act differently. In a 5-week randomized controlled experimental study, we compared an information + MCII intervention with an information-only control intervention. As hypothesized, only MCII participants’ intention of reducing their meat consumption was predictive of their actual reduction, while no correspondence between intention and behavior change was found for control participants. Participants with a moderate to strong intention to reduce their meat consumption reduced it more in the MCII than in the control condition. Thus, MCII helped to narrow the intention-behavior gap and supported behavior change for those holding moderate and strong respective intentions. PMID:27199840

    Except for the loss of its ring of ejecta, the crater at the leading edge of this streamlined island in Kasei Vallis, imaged here by NASA Mars Odyssey, shows no hint of the catastrophic floods that passed by it. Kasei Vallis is one of several major outflow channel systems that were active over 3 billion years ago. The intense floods scoured the landscape, eroding craters and producing streamlined islands. But in a close-up view, the evidence for these floods is not apparent. This true of the most similar terrestrial example, the channeled scablands of eastern Washington which also were formed by a catastrophic flood. http://photojournal.jpl.nasa.gov/catalog/PIA04022

  20. The readiness potential reflects intentional binding

    2014-01-01

    When a voluntary action is causally linked with a sensory outcome, the action and its consequent effect are perceived as being closer together in time. This effect is called intentional binding. Although many experiments were conducted on this phenomenon, the underlying neural mechanisms are not well understood. While intentional binding is specific to voluntary action, we presumed that preconscious brain activity (the readiness potential, RP), which occurs before an action is made, might play an important role in this binding effect. In this study, the brain dynamics were recorded with electroencephalography (EEG) and analyzed in single-trials in order to estimate whether intentional binding is correlated with the early neural processes. Moreover, we were interested in different behavioral performance between meditators and non-meditators since meditators are expected to be able to keep attention more consistently on a task. Thus, we performed the intentional binding paradigm with 20 mindfulness meditators and compared them to matched controls. Although, we did not observe a group effect on either behavioral data or EEG recordings, we found that self-initiated movements following ongoing negative deflections of slow cortical potentials (SCPs) result in a stronger binding effect compared to positive potentials, especially regarding the perceived time of the consequent effect. Our results provide the first direct evidence that the early neural activity within the range of SCPs affects perceived time of a sensory outcome that is caused by intentional action. PMID:24959135

    It has been recently reported that the electrical charge in a semiconductive carbon nanotube is not evenly distributed, but rather it is divided into charge "islands." This paper links the aforementioned phenomenon to tunneling and provides further insight into the higher rate of tunneling processes, which makes tunneling devices attractive. This paper also provides a basis for calculating the charge profile over the length of the tube so that nanoscale devices' conductive properties may be fully exploited.

    The Republic of Vanuatu, similar to other South Pacific island nations, is undergoing a rapid health transition as a consequence of modernization. The pace of modernization is uneven across Vanuatu's 63 inhabited islands, resulting in differential impacts on overall body composition and prevalence of obesity among islands, and between men and women. In this study, we investigated (1) how modernization impacts body composition between adult male and female Melanesians living on four islands of varying economic development in Vanuatu, and (2) how body composition differs between adult Melanesians and Polynesians living on rural islands in Vanuatu. Anthropometric measurements were taken on adult male and female Melanesians aged 18 years and older (n = 839) on the islands of Ambae (rural), Aneityum (rural with tourism), Nguna (rural with urban access), and Efate (urban) in Vanuatu, in addition to Polynesian adults on Futuna (rural). Mean measurements of body mass and fatness, and prevalence of obesity, were greatest on the most modernized islands in our sample, particularly among women. Additionally, differences between men and women became more pronounced on islands that were more modernized. Rural Polynesians on Futuna exhibited greater body mass, adiposity, and prevalence of obesity than rural Melanesians on Ambae. We conclude that Vanuatu is undergoing an uneven and rapid health transition resulting in increased prevalence of obesity, and that women are at greatest risk for developing obesity-related chronic diseases in urbanized areas in Vanuatu. © 2015 Wiley Periodicals, Inc.

    Few environments on Earth are changing more dramatically than the Arctic. Sea ice retreat and thinning is unprecedented in the period of the satellite record. Surface air temperatures are the warmest in centuries. The biology of Arctic lakes is changing like never before in millennia. Everything is pointing to the meltdown predicted by climate model simulations for the next 100 years. At the same time, the Arctic remains one of the most pristine and beautiful places on Earth. For both those who know the Arctic and those who want to know it, this book is worth its modest price. There is much more to the Arctic than its islands, but there's little doubt that Greenland and the major northern archipelagos can serve as a great introduction to the environment and magnificence of the Arctic. The book uses the islands of the Arctic to give a good introduction to what the Arctic environment is all about. The first chapter sets the stage with an overview of the geography of the Arctic islands, and this is followed by chapters that cover many key aspects of the Arctic: the geology (origins), weather and climate, glaciers, ice sheets, sea ice, permafrost and other frozen ground issues, coasts, rivers, lakes, animals, people, and environmental impacts. The material is pitched at a level well suited for the interested layperson, but the book will also appeal to those who study the science of the Arctic.

  7. Self-Organizing Systems Show Apparent Intentionality

    Tschacher, Wolfganfg; Dauwalder, Jean-Pierre; Haken, Hermann

    Cognitive science is frequently confronted with mind-body issues—is there a way by which the mentalist and the physical approaches to cognition can be integrated? Can the intentional attributes of mind be understood in physical terms? We propose that synergetics, the theory of nonlinear complex systems, offers steps towards a possible solution to this notorious problem. In particular, we claim that an essential property of self-organized pattern formation lies in its functionality, i.e. the ability to respond and adapt 'meaningfully' to environmental constraints. Patterns become functional because they consume the gradients that caused their evolution, and, in addition, they consume them in the most efficient manner. This makes synergetic pattern formation appear 'intentional'. Therefore, we suggest that self-organization phenomena may be considered basic explanations of the adaptive, intentional, and purposive behavior of many complex systems, in particular cognitive systems.

    Turnover of nurse faculty is an increasingly important issue in nursing as the available number of qualified faculty continues to decrease. Understanding the factors that contribute to turnover is important to academic administrators to retain and recruit qualified nursing faculty. The purpose of this study was to examine predictors of turnover intention in nurse faculty working in departments and schools of nursing in Carnegie Doctoral/Research Universities-Extensive, public and private, not-for-profit institutions. The multidimensional model of organizational commitment was used to frame this study. The predictor variables explored were organizational climate, organizational commitment, work role balance, role ambiguity, and role conflict. The work roles examined were research, teaching, and service. Logistical regression was performed to examine the predictors of turnover intention. Organizational climate intimacy and disengagement, affective and continuance organizational commitment, and role ambiguity were shown to predict turnover intention in nurse faculty.

    This study examined the role that illness perceptions, attitudes toward depression treatments, and subjective norms played in Latino immigrants’ intentions to seek depression care. Ninety-five Latino immigrant patients were presented a vignette depicting an individual with major depression and interviewed about their intentions to seek care if confronted with a similar situation. Patients’ preferences were to rely on informal sources of care first, and then turn to formal sources to cope with depression. Findings showed Latinos immigrants’ help-seeking intentions for depression were a function of their views of depression, attitudes toward their doctors’ interpersonal skills, and social norms related to seeking professional care after controlling for demographics, health insurance status, acculturation, clinical characteristics, perceived barriers to care, and past service use.

    Alien species, one of the biggest threats to natural ecosystems worldwide, are of particular concern for oceanic archipelagos such as Galápagos. To enable more effective management of alien species, we reviewed, collated and analysed all available records of alien species for Galápagos. We also assembled a comprehensive dataset on pathways to and among the Galápagos Islands, including tourist and resident numbers, tourist vessels, their itineraries and visitation sites, aircraft capacity and occupancy, air and sea cargo and biosecurity interceptions. So far, 1,579 alien terrestrial and marine species have been introduced to Galápagos by humans. Of these, 1,476 have become established. Almost half of these were intentional introductions, mostly of plants. Most unintentional introductions arrived on plants and plant associated material, followed by transport vehicles, and commodities (in particular fruit and vegetables). The number, frequency and geographic origin of pathways for the arrival and dispersal of alien species to and within Galápagos have increased over time, tracking closely the increase in human population (residents and tourists) on the islands. Intentional introductions of alien species should decline as biosecurity is strengthened but there is a danger that unintentional introductions will increase further as tourism on Galápagos expands. This unique world heritage site will only retain its biodiversity values if the pathways for invasion are managed effectively.

    Nanohoneycomb (NHC) amorphous Bi thin films, made by thermal evaporation onto substrates that contain a nanometer-scale array of holes and regular surface height variations, exhibit an insulating phase of localized Cooper pairs. Recently, we described how thickness variations induced by the substrate height variations can give rise to superconducting island formation.ootnotetextHollen et. al., Phys. Rev. B, 84(6), August 2011. This work is supported by the AAUW, the NSF through Grant No. DMR-0605797 and No. DMR-0907357, by the AFRL, and by the ONR. Here, we will present an extension of this analysis to suggest how the island sizes evolve through the magnetic field-driven superconductor-insulator transition. Using this islanding picture, we will discuss the applicability of a granular array model to explain the appearance and behavior of the CPI phase in these films. Finally, we will discuss recent experimental tests of this proposal for thickness-undulation-driven Cooper pair localization.

  14. Nurses' intentions to give lifestyle support.

    PubMed

    McKenzie, Karen

    Models of behaviour change can help identify factors that influence health behaviours such as eating a healthy diet and physical activity. The Theory of Planned Behaviour has been shown to be relatively effective at predicting people's intention to engage in health-related behaviours. More recent research has explored whether it can help predict the intentions of one group of people to support another group to engage in healthy behaviour. This has implications for nurses, who are often facilitators of patient health. This article gives an overview of the model and discusses its potential implications for nurses.

    Easter Island (Rapa Nui) provides a model of human-induced environmental degradation. A reliable chronology is central to understanding the cultural, ecological, and demographic processes involved. Radiocarbon dates for the earliest stratigraphic layers at Anakena, Easter Island, and analysis of previous radiocarbon dates imply that the island was colonized late, about 1200 A.D. Substantial ecological impacts and major cultural investments in monumental architecture and statuary thus began soon after initial settlement.

    2014-08-01

    Non-intentional and deliberate burns in India and other developing countries present particular challenges of prevention and treatment. This exploratory study sought improved understanding of burns in order to inform treatment and prevention. It gathered data in 2011/2012 on burns from the hospital registry (N=768) of a government hospital in India and from interviews with women patients (N=60) admitted to the burns ward. Analysis indicated that: (1) the conditions that facilitate intentional and non-intentional burns are similar, but intentional burns involve additional contributory factors; (2) a high proportion of patients subjected to burns are young women in domestic situations; and (3) a higher proportion of their TBSA was burned, with consequent higher mortality than for men. It was concluded that: (1) Haddon's matrix and the situational crime prevention framework of criminology assist in understanding the etiology of intentional burns and in identifying preventive measures; (2) social service and criminal justice agencies have important roles in dealing with victims of intentional burns during and after treatment; (3) full account should be taken of gender-related physical, psychological and family factors in planning treatment; and (4) maintaining careful records of burns cases is vital for estimating the prevalence and incidence of intentional injuries.

  3. Island biogeography of the Anthropocene.

    Helmus, Matthew R; Mahler, D Luke; Losos, Jonathan B

    2014-09-25

    For centuries, biogeographers have examined the factors that produce patterns of biodiversity across regions. The study of islands has proved particularly fruitful and has led to the theory that geographic area and isolation influence species colonization, extinction and speciation such that larger islands have more species and isolated islands have fewer species (that is, positive species-area and negative species-isolation relationships). However, experimental tests of this theory have been limited, owing to the difficulty in experimental manipulation of islands at the scales at which speciation and long-distance colonization are relevant. Here we have used the human-aided transport of exotic anole lizards among Caribbean islands as such a test at an appropriate scale. In accord with theory, as anole colonizations have increased, islands impoverished in native species have gained the most exotic species, the past influence of speciation on island biogeography has been obscured, and the species-area relationship has strengthened while the species-isolation relationship has weakened. Moreover, anole biogeography increasingly reflects anthropogenic rather than geographic processes. Unlike the island biogeography of the past that was determined by geographic area and isolation, in the Anthropocene--an epoch proposed for the present time interval--island biogeography is dominated by the economic isolation of human populations.

  4. Cognitive Constraints and Island Effects

    2012-01-01

    Competence-based theories of island effects play a central role in generative grammar, yet the graded nature of many syntactic islands has never been properly accounted for. Categorical syntactic accounts of island effects have persisted in spite of a wealth of data suggesting that island effects are not categorical in nature and that non-structural manipulations that leave island structures intact can radically alter judgments of island violations. We argue here, building on work by Deane, Kluender, and others, that processing factors have the potential to account for this otherwise unexplained variation in acceptability judgments. We report the results of self-paced reading experiments and controlled acceptability studies which explore the relationship between processing costs and judgments of acceptability. In each of the three self-paced reading studies, the data indicate that the processing cost of different types of island violations can be significantly reduced to a degree comparable to that of non-island filler-gap constructions by manipulating a single non-structural factor. Moreover, this reduction in processing cost is accompanied by significant improvements in acceptability. This evidence favors the hypothesis that island-violating constructions involve numerous processing pressures that aggregate to drive processing difficulty above a threshold so that a perception of unacceptability ensues. We examine the implications of these findings for the grammar of filler-gap dependencies.* PMID:22661792

  5. Spatial localization of resistive drift wave structure in tokamak edge plasmas with an embedded magnetic island

    Resistive drift wave instability is investigated numerically in tokamak edge plasma confined by sheared slab magnetic field geometry with an embedded magnetic island. The focus is on the structural characteristics of eigenmode inside the island, where the density profile tends to be flattened. A transition of the dominant eigenmode occurs around a critical island width w{sub c}. For thin islands with a width below w{sub c}, two global long wavelength eigenmodes with approximately the same growth rate but different eigenfrequency are excited, which are stabilized by the magnetic island through two-dimensional mode coupling in both x and y (corresponding to radial and poloidal in tokamak) directions. On the other hand, a short wavelength eigenmode, which is destabilized by thick islands with a width above w{sub c}, dominates the edge fluctuation, showing a prominent structural localization in the region between the X-point and the O-point of the magnetic island. The main destabilization mechanism is identified as the mode coupling in the y direction, which is similar to the so-called toroidal coupling in tokamak plasmas. These three eigenmodes may coexist in the drift wave fluctuation for the island with a width around w{sub c}. It is demonstrated that the structural localization results mainly from the quasilinear flattening of density profile inside the magnetic island.

  6. Spontaneous healing and growth of locked magnetic island chains in toroidal plasmas

    2012-11-15

    Recent experiments have demonstrated that locked magnetic island chains in stellarator plasmas spontaneously heal under certain conditions, and spontaneously grow under others. A formalism initially developed to study magnetic island dynamics in tokamak plasmas is employed to investigate this phenomenon. It is found that island healing/growth transitions can be caused either by a breakdown in torque balance in the vicinity of the island chain, or by an imbalance between the various terms in the island width evolution equation. The scaling of the healing/growth thresholds with the standard dimensionless plasma parameters {beta}, {nu}{sub *}, and {rho}{sub *} is determined. In accordance with the experimental data, it is found that island healing generally occurs at high {beta} and low {nu}{sub *}, and island growth at low {beta} and high {nu}{sub *}. In further agreement, it is found that island healing is accompanied an ion poloidal velocity shift in the electron diamagnetic direction, and island growth by a velocity shift in the ion diamagnetic direction. Finally, it is found that there is considerable hysteresis in the healing/growth cycle, as is also seen experimentally.

  7. Tree island pattern formation and alternative equilibria in the Florida Everglades

    NASA Astrophysics Data System (ADS)

    The tree islands of the Florida Everglades are patterned ecogeomorphic features where elevated woody vegetation patches are surrounded by wet marsh filled with herbaceous vegetation. This wet savanna landscape exhibits an uneven distribution of soil resources with enhanced soil phosphorus concentrations underlying elevated tree islands. In contrast, the surrounding low lying marsh has low phosphorous availability. This patchy patterned landscape sustains high levels of biodiversity, but the processes determining the stability and resilience of the patterned tree island landscape remains poorly understood. In particular, it is unclear what controls the relation between individual form and processes within a tree island and the spatial organization of tree islands on the landscape. To this end, a process-based model that relates vegetation dynamics to nutrients and soil accretion/loss through ecogeomorphic feedbacks and interactions with hydrologic drivers was developed. The model reveals that the stable coexistence of tree islands and marshes emerges as an effect of their both being (meta-) stable states of the system. Self organization of patterns on the landscape occurs within a subset of the parameter space. As such, tree islands are found to have only a limited resilience. Change in hydroperiod and or vegetation cover can result in an rapid shift to a stable marsh state. Under certain hydrologic conditions this state can become destabilized and promote once again ontogenesis of tree islands. As such, the tree island susceptibility to a rapid (slow) transition between alternative equilibria needs to be accounted for while developing a plan for their management, conservation and restoration.

  8. Promoting the translation of intentions into action by implementation intentions: behavioral effects and physiological correlates

    2015-01-01

    The present review addresses the physiological correlates of planning effects on behavior. Although intentions to act qualify as predictors of behavior, accumulated evidence indicates that there is a substantial gap between even strong intentions and subsequent action. One effective strategy to reduce this intention–behavior gap is the formation of implementation intentions that specify when, where, and how to act on a given goal in an if-then format (“If I encounter situation Y, then I will initiate action Z!”). It has been proposed that implementation intentions render the mental representation of the situation highly accessible and establish a strong associative link between the mental representations of the situation and the action. These process assumptions have been examined in behavioral research, and in physiological research, a field that has begun to investigate the temporal dynamics of and brain areas involved in implementation intention effects. In the present review, we first summarize studies on the cognitive processes that are central to the strategic automation of action control by implementation intentions. We then examine studies involving critical samples with impaired self-regulation. Lastly, we review studies that have applied physiological measures such as heart rate, cortisol level, and eye movement, as well as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) studies on the neural correlates of implementation intention effects. In support of the assumed processes, implementation intentions increased goal attainment in studies on cognitive processes and in critical samples, modulated brain waves related to perceptual and decision processes, and generated less activity in brain areas associated with effortful action control. In our discussion, we reflect on the status quo of physiological research on implementation intentions, methodological and conceptual issues, related research, and propose future

  9. Relational care: learning to look beyond intentionality to the 'non-intentional' in a caring relationship.

    PubMed

    Greenwood, Dennis

    2007-10-01

    This paper considers the implications for nursing practice of what the continental philosopher Emmanuel Levinas described as the 'non-intentional'. The place of the non-intentional emerges from a critique of Buber's conception of the 'I-Thou' and the 'I-It' relations, and is revealed to a person in the moments prior to the grasping of conscious understanding. A specific incident that took place between a nurse and a person diagnosed with dementia is described and then used to illustrate an exploration of the 'I-Thou' relation and then the non-intentional. The nurse practitioner's pre-understandings of the term dementia are shown to have hindered the emergence of an 'I-Thou' relation and the possibility of a non-intentional glimpse of the otherness of the other. It is suggested here that the plausible associations that become synonymous with a diagnosis like dementia detract from attentiveness to another 'person'. The more tangible an understanding of another person becomes, the less likely it is that a person can really experience the other as separate to their perception of them. The implications for practitioner education and learning in relation to the non-intentional are considered, in particular the need to reflect on the immediacy of the feelings experienced in a relationship. The non-intentional highlights how 'I', as a nurse practitioner, can exclude the other by imposing an understanding on what is seen and experienced in relation to another person. The 'I' prioritizes intentional understanding and so obscures the importance of the spontaneous response to the tear in the eye of the other, which is the basis for Levinas's conception of the non-intentional. The spontaneity of the non-intentional is what Levinas believed confirmed the separateness and autonomy of the other and consequently should be the basis for a therapeutic nursing relationship with a patient.

    1988-01-01

    1 area of intra-Caribbean migration that has been overlooked is the "migration transition"--the transformation of rapidly modernizing societies from net labor exporters to net labor importers. This article assembles 8 case studies to 1) briefly present a spectrum of migration experiences in the Caribbean, 2) uncover some transitions under way, 3) pinpoint the forces that underlie the migration transition, and 4) point out some of the more important policy implications of labor migration reversals. The 8 island societies sampled for illustration purposes include 1) the Bahamas and the US Virgin Islands as post-migration transition societies (Zelinsky's advanced society), 2) the British Virgin Islands and the Cayman Islands as undergoing transition (Zelinsky's late transitional society), and 3) Anguilla, St. Kitts-Nevis, Turks and Caicos, and Montserrat as premigration transition societies (Zelinsky's early transitional society). Population data for the islands were derived primarily from the West Indian censuses and government statistics. These 8 historical sketches reveal certain commonalities. All are at various stages in a long-term economic restructuring to displace traditional staple crops with more income elastic, high value export services. In such societies, population growth and progress along the migration transition is an increasing function of this kind of successful export substitution. In addition, along the migration and economic transitions, such insular economies exhibit a relatively large public sector (20-30% of all activity), declining unemployment, increasing fiscal autonomy, and are committed to a development strategy remarkably similar to the "successful" model of the Bahamas and the US Virgin Islands. Cursory evidence suggests that, because of intersectoral competition for land and labor, there is an inverse relationship between farm effort/manufacturing employment and tourism intensity. This review suggests that small islands undergoing

    On January 16, 2002, lava that had begun flowing on January 5 from the Piton de la Fournaise volcano on the French island of Reunion abruptly decreased, marking the end of the volcano's most recent eruption. These false color MODIS images of Reunion, located off the southeastern coast of Madagascar in the Indian Ocean, were captured on the last day of the eruption (top) and two days later (bottom). The volcano itself is located on the southeast side of the island and is dark brown compared to the surrounding green vegetation. Beneath clouds (light blue) and smoke, MODIS detected the hot lava pouring down the volcano's flanks into the Indian Ocean. The heat, detected by MODIS at 2.1 um, has been colored red in the January 16 image, and is absent from the lower image, taken two days later on January 18, suggesting the lava had cooled considerably even in that short time. Earthquake activity on the northeast flank continued even after the eruption had stopped, but by January 21 had dropped to a sufficiently low enough level that the 24-hour surveillance by the local observatory was suspended. Reunion is essentially all volcano, with the northwest portion of the island built on the remains of an extinct volcano, and the southeast half built on the basaltic shield of 8,630-foot Piton de la Fournaise. A basaltic shield volcano is one with a broad, gentle slope built by the eruption of fluid basalt lava. Basalt lava flows easily across the ground remaining hot and fluid for long distances, and so they often result in enormous, low-angle cones. The Piton de la Fournaise is one of Earth's most active volcanoes, erupting over 150 times in the last few hundred years, and it has been the subject of NASA research because of its likeness to the volcanoes of Mars.

  15. The emergence of volcanic oceanic islands on a slow-moving plate: The example of Madeira Island, NE Atlantic

    The transition from seamount to oceanic island typically involves surtseyan volcanism. However, the geological record at many islands in the NE Atlantic—all located within the slow-moving Nubian plate—does not exhibit evidence for an emergent surtseyan phase but rather an erosive unconformity between the submarine basement and the overlying subaerial shield sequences. This suggests that the transition between seamount and island may frequently occur by a relative fall of sea level through uplift, eustatic changes, or a combination of both, and may not involve summit volcanism. In this study, we explore the consequences for island evolutionary models using Madeira Island (Portugal) as a case study. We have examined the geologic record at Madeira using a combination of detailed fieldwork, biostratigraphy, and 40Ar/39Ar geochronology in order to document the mode, timing, and duration of edifice emergence above sea level. Our study confirms that Madeira's subaerial shield volcano was built upon the eroded remains of an uplifted seamount, with shallow marine sediments found between the two eruptive sequences and presently located at 320-430 m above sea level. This study reveals that Madeira emerged around 7.0-5.6 Ma essentially through an uplift process and before volcanic activity resumed to form the subaerial shield volcano. Basal intrusions are a likely uplift mechanism, and their emplacement is possibly enhanced by the slow motion of the Nubian plate relative to the source of partial melting. Alternating uplift and subsidence episodes suggest that island edifice growth may be governed by competing dominantly volcanic and dominantly intrusive processes.

Our study confirms that Madeira's subaerial shield volcano was built upon the eroded remains of an uplifted seamount, with shallow marine sediments found between the two eruptive sequences and presently located at 320–430 m above sea level. This study reveals that Madeira emerged around 7.0–5.6 Ma essentially through an uplift process and before volcanic activity resumed to form the subaerial shield volcano. Basal intrusions are a likely uplift mechanism, and their emplacement is possibly enhanced by the slow motion of the Nubian plate relative to the source of partial melting. Alternating uplift and subsidence episodes suggest that island edifice growth may be governed by competing dominantly volcanic and dominantly intrusive processes.

  17. Archipelago-Wide Island Restoration in the Galápagos Islands: Reducing Costs of Invasive Mammal Eradication Programs and Reinvasion Risk

    PubMed Central

    Carrion, Victor; Donlan, C. Josh; Campbell, Karl J.; Lavoie, Christian; Cruz, Felipe

    2011-01-01

    Invasive alien mammals are the major driver of biodiversity loss and ecosystem degradation on islands. Over the past three decades, invasive mammal eradication from islands has become one of society's most powerful tools for preventing extinction of insular endemics and restoring insular ecosystems. As practitioners tackle larger islands for restoration, three factors will heavily influence success and outcomes: the degree of local support, the ability to mitigate for non-target impacts, and the ability to eradicate non-native species more cost-effectively. Investments in removing invasive species, however, must be weighed against the risk of reintroduction. One way to reduce reintroduction risks is to eradicate the target invasive species from an entire archipelago, and thus eliminate readily available sources. We illustrate the costs and benefits of this approach with the efforts to remove invasive goats from the Galápagos Islands. Project Isabela, the world's largest island restoration effort to date, removed >140,000 goats from >500,000 ha for a cost of US$10.5 million. Leveraging the capacity built during Project Isabela, and given that goat reintroductions have been common over the past decade, we implemented an archipelago-wide goat eradication strategy. Feral goats remain on three islands in the archipelago, and removal efforts are underway. Efforts on the Galápagos Islands demonstrate that for some species, island size is no longer the limiting factor with respect to eradication. Rather, bureaucratic processes, financing, political will, and stakeholder approval appear to be the new challenges. Eradication efforts have delivered a suite of biodiversity benefits that are in the process of revealing themselves. The costs of rectifying intentional reintroductions are high in terms of financial and human resources. Reducing the archipelago-wide goat density to low levels is a technical approach to reducing reintroduction risk in the short-term, and is being

  19. Islands and Non-islands in Native and Heritage Korean.

    To a large extent, island phenomena are cross-linguistically invariable, but English and Korean present some striking differences in this domain. English has wh-movement and Korean does not, and while both languages show sensitivity to wh-islands, only English has island effects for adjunct clauses. Given this complex set of differences, one might expect Korean/English bilinguals, and especially heritage Korean speakers (i.e., early bilinguals whose L2 became their dominant language during childhood) to be different from native speakers, since heritage speakers have had more limited exposure to Korean, may have had incomplete acquisition and/or attrition, and may show significant transfer effects from the L2. Here we examine islands in heritage speakers of Korean in the U.S. Through a series of four formal acceptability experiments comparing these heritage speakers with native speakers residing in Korea, we show that the two groups are remarkably similar. Both show clear evidence for wh-islands and an equally clear lack of adjunct island effects. Given the very different linguistic environment that the heritage speakers have had since early childhood, this result lends support to the idea that island phenomena are largely immune to environmental influences and stem from deeper properties of the processor and/or grammar. Similarly, it casts some doubt on recent proposals that islands are learned from the input.

    The phenomenon of urban heat island was investigated by the use of LANDSAT Thematic Mapper data sets collected over the metropolitan area of Washington DC (U.S.). By combining the retrieved spectral albedos and temperatures, urban modification on radiation budgets of five surface categories were analyzed. The surface radiation budget imagery of the area show that urban heating is attributable to a large heat flux from the rapidly heating surfaces of asphalt, bare soil and short grass. In summer, symptoms of diurnal heating begin to appear by mid morning and can be about 10 degrees warmer than nearby woodlands in summer.

    The submental island flap is a reliable source of skin of excellent colour, contour and texture match for facial resurfacing and leaves a well hidden donor site. The flap is safe, rapid and simple to raise. We report on its use in 12 cases of facial or intraoral reconstruction. Complications were few. However, there was one case of complete flap loss following its use in a reverse flow manner, due to the presence of an unreported, but constant, valve in the venous system of the face. We believe this flap to be a worthwhile addition to the existing surgical armamentarium.

    Disease screening instruments used for secondary prevention can facilitate early determination and treatment of pathogenic factors, effectively reducing disease incidence, mortality rates, and health complications. Therefore, people should be encouraged to receive health examinations for discovering potential pathogenic factors before symptoms occur. Here, we used the health belief model as a foundation and integrated social psychological factors and investigated the factors influencing health examination behavioral intention among the public in Taiwan. In total, 388 effective questionnaires were analyzed through structural model analysis. Consequently, this study yielded four crucial findings: (1) The established extended health belief model could effectively predict health examination behavioral intention; (2) Self-efficacy was the factor that most strongly influenced health examination behavioral intention, followed by health knowledge; (3) Self-efficacy substantially influenced perceived benefits and perceived barriers; (4) Health knowledge and social support indirectly influenced health examination behavioral intention. The preceding results can effectively increase the acceptance and use of health examination services among the public, thereby facilitating early diagnosis and treatment and ultimately reducing disease and mortality rates.

    Wilson et al. draw our attention to the problem of a science of intentional change. We stress the connection between their approach and existing paradigms for learning and goal generation that have been developed in machine learning, artificial intelligence, and psychology. These paradigms outline the structural principles of a domain-general and teleologically open agent.

  20. Rain on small tropical islands

    A high-resolution rainfall climatology based on observations from the Tropical Rainfall Measuring Mission's Precipitation Radar (PR) instrument is used to evaluate the influence of small tropical islands on climatological rainfall. Islands with areas between one hundred and several thousand km2 are considered in both the Indo-Pacific Maritime Continent and Caribbean regions. Annual mean climatological (1997-2007) rainfall over each island is compared with that over the surrounding ocean region, and the difference is expressed as a percentage. In addition to total rainfall, rain frequency and intensity are also analyzed. Results are stratified into two 12 h halves of the diurnal cycle as well as eight 3 h periods, and also by a measure of each island's topographic relief. In both regions, there is a clear difference between larger islands (areas of a few hundred km2 or greater) and smaller ones. Both rain frequency and total rainfall are significantly enhanced over larger islands compared to the surrounding ocean. For smaller islands the enhancement is either negligibly small, statistically insignificant, or, in the case of Caribbean rain frequency, negative. The enhancement in total rainfall over larger islands is partly attributable to greater frequency and partly to greater intensity. A diurnal cycle in island enhancement is evident in frequency but not intensity, except over small Caribbean islands where the converse is true. For the larger islands, higher orography is associated with greater rainfall enhancements. The orographic effect is larger (percentagewise) in the Caribbean than in the Maritime Continent. Orographic precipitation enhancement manifests more strongly as increased frequency of precipitation rather than increased intensity and is present at night as well as during the day. The lack of a clear diurnal cycle in orographic enhancement suggests that much of the orographic rainfall enhancement is attributable to mechanically forced upslope flow
