Dataciones geocronológicas preliminares en la Cuenca Cañadón Asfalto, Jurásico de Chubut, Argentina : Implicancias geológicas y paleontológicas

La Cuenca Cañadón Asfalto corresponde a una serie de depocentros aflorantes a lo largo del valle medio del río Chubut como parte de una cuenca de rift desarrollada probablemente desde el Triásico. Sin embargo, la posibilidad de contar con un control cronológico de los eventos, tanto geológicos como biológicos, que acontecieron en la época y representan uno de los mejores registros de la biota jurásica del mundo, ha sido incierta, habiendo estado los mismos únicamente referidos a restos de microfósiles. Recientemente, como parte de un proyecto mayor de relevamiento de los yacimientos paleontológicos del área, además de realizarse un remuestreo palinológico detallado, se ha iniciado una colección sistemática de intercalaciones de cenizas volcánicas en distintas secciones de la secuencia general. Presentamos aquí los primeros datos sobre algunas de estas intercalaciones, las cuales permiten establecer que los términos basales de la Formación Cañadón Asfalto, en el depocentro Cerro Cóndor, comenzaron a depositarse hacia fines del Jurásico Temprano (Toarciano), y probablemente continuaron durante casi todo el Jurásico Medio. Esto significa que, por ejemplo, la infrayacente Formación Lonco Trapial ha sido mayoritariamente depositada durante el Jurásico Temprano, probablemente en un lapso no demasiado prolongado tal como lo sugieren las paleofloras también del Jurásico Temprano preservadas inmediatamente por debajo de la misma. Por su parte, en aquellos depocentros donde se desarrolló la Formación Cañadón Calcáreo, la misma pareciera demostrar una cierta continuidad, con su sector basal iniciando su depositación en el Jurásico Tardío y probablemente culminando en el Cretácico Temprano. Asimismo, los centros de depositación septentrionales de la cuenca (ex Formación Cañadón Asfalto), parecen demostrar que su sedimentación transcurrió principalmente durante el Jurásico Temprano. Sobre esta base, la dinámica temporal en la depositación de sedimentitas jurásicas en la cuenca Cañadón Asfalto, debió haber estado sujeta a una constante reactivación de los márgenes y aperturas cuencales que muestran un tren relativamente coetáneo a lo largo de su historia.Sesiones libresFacultad de Ciencias Naturales y Muse

The Avon Longitudinal Study of Parents and Children - A resource for COVID-19 research: Questionnaire data capture November 2020 – March 2021

The Avon Longitudinal Study of Parents and Children (ALSPAC) is a prospective population-based cohort study which recruited pregnant women in 1990-1992 and has followed these women, their partners (Generation 0; G0) and their offspring (Generation 1; G1) ever since. The study has reacted rapidly and repeatedly to the coronavirus disease 2019 (COVID-19) pandemic, deploying online questionnaires throughout the pandemic. In November/December 2020, a fourth questionnaire was deployed asking about physical and mental health, lifestyle and behaviours, employment and finances. G0 participants were offered an online questionnaire between 17th November 2020 and 7th February 2021, while G1 participants were offered both online and paper questionnaires between 1st December 2020 and 19th March 2021. Of 15,844 invitations, 8,643 (55%) participants returned the questionnaire (3,101 original mothers [mean age 58.6 years], 1,172 original fathers/partners [mean age 61.5 years] and 4,370 offspring [mean age 28.4 years]). Of these 8,643 participants, 2,012 (23%) had not returned a previous COVID-19 questionnaire, while 3,575 (41%) had returned all three previous questionnaires. In this questionnaire, 300 participants (3.5%) reported a previous positive COVID-19 test, 110 (1.3%) had been told by a doctor they likely had COVID-19, and 759 (8.8%) suspected that they had had COVID-19. Based on self-reported symptoms, between October 2020 and February 2021 359 participants (4.2%) were predicted COVID-19 cases. COVID data is being complemented with linkage to health records and Public Health England pillar testing results as they become available. Data has been released as an update to the previous COVID-19 datasets. It comprises: 1) a standard dataset containing all participant responses to both questionnaires with key sociodemographic factors; and 2) as a composite release coordinating data from the existing resource, thus enabling bespoke research across all areas supported by the study. This data note describes the fourth questionnaire and the data obtained from it

Pro-active Meeting Assistants: Attention Please!

This paper gives an overview of pro-active meeting assistants, what they are and when they can be useful. We explain how to develop such assistants with respect to requirement definitions and elaborate on a set of Wizard of Oz experiments, aiming to find out in which form a meeting assistant should operate to be accepted by participants and whether the meeting effectiveness and efficiency can be improved by an assistant at all.

Toward data-based clinical decision making for adults with challenging behavior using the Behavior Problems Inventory-Short Form (BPI-S)

Purpose: The Behavior Problems Inventory-Short Form (BPI-S) is a shorter version of the Behavior Problems Inventory-01. In this paper, BPI-S population norms are reported from a total administrative population of adults with intellectual disability (ID). To facilitate the use of the BPI-S in clinical services to assess behavior change, the purpose of this paper is to describe how to use BPI-S clinically significant and reliable change (RC) scores. Design/methodology/approach: Data were gathered on 265 adults with ID known to services. Proxy informants completed the BPI-S on challenging behaviors over the previous six months. Clinically significant cut-off values and RC scores were calculated using the Jacobson and Truax’s (1991) method. Findings: BPI-S clinical reference data are presented to provide benchmarks for individual and group comparisons regarding challenging behavior. Examples demonstrate how to use clinical norms to determine change. Practical implications: Behavior change is a major goal of researchers and practitioners. Data from the present study can make the BPI-S a valuable tool for determining change in challenging behavior following service input or intervention. Originality/value: Whilst well used in research, the BPI-S may be less extensively used in practice. This present study provides data to enable researchers and practitioners to use the BPI-S more widely in assessing clinical outcomes, such as intervention research and service evaluation

Faster with CLEAN - An exploration of the effects of applying a nonlinear deconvolution method to a novel radiation mapper

This paper examines the suitability and potential of reducing the acquisition requirements of a novel radiation mapper through the application of the non-linear deconvolution technique, CLEAN. The radiation mapper generates a threshold image of the target scene, at a user defined distance, using a single pixel detector manually scanned across the scene. This paper provides a discussion of the factors involved and merits of incorporating CLEAN into the system. In this paper we describe the modifications to the system for the generation of an intensity map and the relationship between resolution and acquisition time for a target scene. The factors influencing image fidelity for a scene are identified and discussed with the impact on fill-factor of the intensity image, which in turn determines the ability of the operator to accurately identify features of the radiation source within a target scene. The CLEAN algorithm and its variants have been extensively developed by the radio astronomy community to improve the image fidelity of data collected by sparse interferometric arrays. However, the algorithm has demonstrated surprising adaptability including terrestrial imagery, as detailed in Taylor et al. SPIE 9078-19 and Bose et al., IEEE 2002. CLEAN can be applied directly to raw data via a bespoke algorithm. However, this investigation is a proof-of-concept and thus requires a well tested verification method. We have opted to use the public ally available implementation of CLEAN found in the Common Astronomy Software Applications (CASA) package. The use of CASA for this purpose dictates the use of simulated input data and radio astronomy standard parameters. Finally, this paper presents the results of applying CLEAN to our simulated target scene, with a discussion of the potential merits a bespoke implementation would yield

Challenging behaviours in adults with an intellectual disability: A total population study and exploration of risk indices

Objectives Considerable variation has been reported in the prevalence and correlates of challenging behaviour (CB) in adults with intellectual disabilities (ID). To provide a robust estimate of prevalence, we identified the entire administrative population of adults with ID in a defined geographical area and used a behaviour assessment tool with good psychometric properties. Methods Data from 265 adults who were known to services were collected using a demographic survey tool and the Behavior Problems Inventory – Short Form. The prevalence of self‐injurious, aggressive/destructive, stereotyped, and overall CB was evaluated. We explored the potential of developing cumulative risk indices (CRI) to inform longitudinal research and clinical practice. Results The prevalence of overall CB was 18.1% (95% CI: 13.94–23.19%). The prevalence of self‐injurious behaviour was 7.5% (95% CI: 4.94–11.37%), aggressive–destructive behaviour 8.3% (95% CI: 5.54–12.25%), and stereotyped behaviour 10.9% (95% CI: 7.73–15.27%). Communication problems and severity of ID were consistently associated with higher risk of CBs. CRIs were significantly associated with CBs, and the five methods of CRI development produced similar results. Conclusions Findings suggest a multi‐element response to CB is likely to be required that includes interventions for communication and daytime activity. Exploratory analyses of CRIs suggested these show promise as simple ways to capture cumulative risk in this population. Subject to longitudinal replication, such a tool may be especially useful in clinical practice to identify adults who are priority for interventions and predict future demand on services
