    Recent research suggests that essential oils of a certain quality can enhance memory consolidation and cognitive performance. The present study examined whether the essential oils rosemary and peppermint were powerful enough to significantly improve short-term memory in recall and recognition tasks. Participants were in a room with a device that diffused a scent or water (no scent) for ten minutes prior to their entry. The participants viewed word lists and were later tested for accuracy in terms of recall and recognition. Results from a one-way analyses of variance demonstrated that peppermint and rosemary did not significantly improve short-term memory or mood. Stipulations showed marginally significant and significant results in post-hoc analyses

    The Case of Intellectual Disability vs. the Death Penalty: A Foucauldian Analysis of Georgia’s Beyond a Reasonable Doubt Standard of Proof

    Get PDF
    Georgia was the first state in the United States to ban the execution of persons with intellectual disability, and did so 14 years prior to the federal mandate in Atkins v. Virginia (2002). In doing so, it became and remains the only state to invoke the highest of standards, beyond a reasonable doubt. When states use a standard higher than the lowest of three, defendants raising the claim of intellectual disability are placed at an increased risk for rights violations that may include lack of due process, the imposition of cruel and unusual punishment, and finally, in the extinction of life. The purpose of this case study is to analyze the 2013 legislative informational hearing hosted by the Georgia House of Representatives Non-Civil Judiciary committee on the state’s standard of proof using Foucault’s medico-judicial perspective. Based on this analysis, the second purpose of the study is to propose a position of advocacy and respective strategy for changing Georgia’s standard of proof of intellectual disability. Lastly, this article recommends a strategy of leveraging the medical model of intellectual disability in the criminal justice context as an instrument for diminishing the risk for unlawful execution and enhancing the securement of accommodations while in state penal custody, as per federal law.Keywords: Intellectual disability; death penalty; medico-judicial discourse; standard of proof; beyond a reasonable doubt; impressionist narrativ

    MILES extended: Stellar population synthesis models from the optical to the infrared

    Get PDF
    We present the first single-burst stellar population models which covers the optical and the infrared wavelength range between 3500 and 50000 Angstrom and which are exclusively based on empirical stellar spectra. To obtain these joint models, we combined the extended MILES models in the optical with our new infrared models that are based on the IRTF (Infrared Telescope Facility) library. The latter are available only for a limited range in terms of both age and metallicity. Our combined single-burst stellar population models were calculated for ages larger than 1 Gyr, for metallicities between [Fe/H] = -0.40 and 0.26, for initial mass functions of various types and slopes, and on the basis of two different sets of isochrones. They are available to the scientific community on the MILES web page. We checked the internal consistency of our models and compared their colour predictions to those of other models that are available in the literature. Optical and near infrared colours that are measured from our models are found to reproduce the colours well that were observed for various samples of early-type galaxies. Our models will enable a detailed analysis of the stellar populations of observed galaxies.Comment: 9 pages, 10 figures, published in A&

    Probabilistic assessment of footbridge response to single walkers

    Get PDF
    Among the load scenarios considered for the serviceability assessment of human-induced footbridge vibration, is that of the transient action of a single pedestrian or a small group of pedestrians. Although such action is stochastic due to the variability of gait parameters, available Codes and Guidelines all assume it is deterministic and equal to that coming from the “worst pedestrian ever” for the given footbridge. This approach is sound from an engineering point of view but does not allow control of the probability of failure. The present work deals with a reliability-based procedure for the serviceability assessment of the footbridge peak characteristic accelerations due to pedestrian induced actions. Based on the results obtained incorporating the effects of the inter-subject variability of gait parameters and of the uncertainties in footbridge dynamic properties, a design response spectrum is proposed for both vertical and lateral vibrations. The proposed procedure lends itself for immediate Code implementation

    Load-carrying capacity of compressed wall-like RC columns strengthened with FRP

    The analytical prediction of the effectiveness of fiber-reinforced polymer (FRP) in the confinement of a rectangular reinforced concrete (RC) column with a high aspect ratio (wall-like) still has an uncertain solution. In this paper, a numerical investigation of the axial response of RC wall-like columns strengthened with FRP systems was developed. Analytical solutions proposed in the literature for the assessment of the axial load capacity were presented and compared with each other and with the available experimental results. Moreover, non-linear finite element analysis was carried out, and the results were discussed, providing a simple model for the assessment of the axial compressive strength of wall-like RC columns strengthened with FRP

    The Relationship between Wind Pressure and Pressure Coefficients for the Definition of Wind Loads on Buildings

    Get PDF
    Wind induced pressures on buildings are the product of a velocity pressure and a pressure coefficient. The way in which these two quantities are calculated has changed over the years, and Design Codes have been modified accordingly. This paper tracks the evolution of the approach to wind loading of buildings from the practice in the 1950s, mainly referring to the Swiss Code SIA, to the most recent advances including probabilistic methods, internet databases, and advanced modelling of meteorological phenomena

    Public Perceptions of the Stigmatization of Wrongly Convicted Individuals: Findings from Semi-Structured Interviews

    Get PDF
    Many exonerees report stigmatizing experiences and difficulties securing gainful employment post-incarceration. Although researchers have begun to investigate public perceptions of wrongful conviction, there remains a dearth of knowledge about public perceptions of exonerees. To provide insight into how the public perceives exonerees, face-to-face interviews were conducted with members (n=30) of a suburban city in South Central Ontario. Data analysis included a constructed grounded approach to reveal emergent themes in the transcripts. All interviewees acknowledged that wrongly convicted individuals are stigmatized by the public and that this can have negative effects in many of their lived experiences. In addition, findings of this exploratory study suggest that some interviewees, indirectly or directly, stigmatize exonerees in their responses while being interviewed—lending insight into how the public views and reacts to exonerees. Findings and policy implications are theoretically framed in Erving Goffman’s (1963) seminal work on stigma. Implications include the potential role of research and education in informing community members, and all levels of government, about wrongful convictions in general, and the negative implications of stigma, in particular

    The star formation activity in cosmic voids

    Get PDF
    Using a sample of cosmic voids identified in the Sloan Digital Sky Survey Data Release 7, we study the star formation activity of void galaxies. The properties of galaxies living in voids are compared with those of galaxies living in the void shells and with a control sample, representing the general galaxy population. Void galaxies appear to form stars more efficiently than shell galaxies and the control sample. This result cannot be interpreted as a consequence of the bias towards low masses in underdense regions, as void galaxy subsamples with the same mass distribution as the control sample also show statistically different specific star formation rates. This highlights the fact that galaxy evolution in voids is slower with respect to the evolution of the general population. Nevertheless, when only the star-forming galaxies are considered, we find that the star formation rate is insensitive to the environment, as the main sequence is remarkably constant in the three samples under consideration. This fact implies that environmental effects manifest themselves as fast quenching mechanisms, while leaving the non-quenched galaxies almost unaffected, as their star formation activity is largely regulated by the mass of their halo. We also analyse galaxy properties as a function of void-centric distance and find that the enhancement in the star formation activity with respect to the control sample is observable up to a radial distance 1.5Rvoid. This result can be used as a suitable definition of void shells. Finally, we find that larger voids show an enhanced star formation activity in the shells with respect to their smaller counterparts, which could be related to the different dynamical evolution experienced by voids of different size

    Feasibility analysis for floating offshore wind energy

    Purpose The assessment of the economic feasibility of foating ofshore wind farms (FOWFs) plays an important role in the future possible spreading of this challenging technology in the wind power industry. The use of specifc economic analyses is fundamental to point out the potential of FOWFs and to sustain their technical value. Within this topic, the implementation of the FOWF life cycle cost model and producibility analysis in a geographic information system is developed, with the aim of carrying out a feasibility analysis at the territorial scale, for diferent types of foater. Moreover, a simplifed model for a quick life cycle cost assessment is proposed and calibrated. Methods The available cost model is frst validated comparing the costs of FOWFs based on diferent foaters (Semi-Submersible Platform—SSP, Spar Buoy—SB and Tension Leg Platform—TLP) with corresponding results available in the literature. Then, it is implemented in QGIS to be used for territorial-scale analyses and sensitivity analyses of the cost parameters. A feasibility analysis is developed through the main fnancial parameters. Finally, the results are then used to calibrate a simplifed version of the cost model that depends on three main parameters, namely distance to shore, distance from the port of operation and bathymetry. Results and discussion The FOWF cost values are found to be in good agreement with those coming from analytical methods similar to the one from the authors. However, some discrepancies with those based on average costs are observed. Then, the results of the sensitivity analysis are presented as life cycle cost maps, giving an overall picture of the variation of the total cost of FOWF installations on a reference domain. The results show that among the three types of foaters considered here, the SSP proved to be the most promising one, giving lower costs than the SB and the TLP. Moreover, a good agreement between the results in terms of total cost of FOWFs calculated with the analytical and simplifed models for SSPs, SBs and TLPs is observed. Finally, the feasibility analysis showed that the fnancial parameters are more infuenced by the wind speed than by the cost of the farm. Conclusions The paper aims to provide guidance on how to carry out feasibility analyses of a specifc site for FOWF installation, thus supporting decision-making procedures. The approach and the results presented here are meant for use in the early stage of the decision-making process, as a tool for the assessment of the economic feasibility of FOWFs installation
