    The distribution of sulphur, thio-sulphinates (pyruvic acid method), SSC, colour, fresh- and dry matter was analysed in three sections, base, centre, and tip, along the leaf tube of chives. Also the intensity of 28 sensory attributes was determined in these sections by a trained quantitative, descriptive panel. The sections differed in their mouthfeel attributes – centre and basis were juicier and crisper than the tips, which were strawy/fibrous and drier. At higher pyruvic acid and SSC concentrations in the tips, more punceny and sweetness was expected, but no increased values were found. Very low juiciness to convey pungent and sweet compounds and very low fresh matter related to leaf length were identified as possible reasons for this inconsistency

    Fluid management in acute kidney injury

    Get PDF
    Acute kidney injury (AKI) and fluids are closely linked through oliguria, which is a marker of the former and a trigger for administration of the latter. Recent progress in this field has challenged the physiological and clinical rational of using oliguria as a trigger for the administration of fluid and brought attention to the delicate balance between benefits and harms of different aspects of fluid management in critically ill patients, in particular those with AKI. This narrative review addresses various aspects of fluid management in AKI outlining physiological aspects, the effects of crystalloids and colloids on kidney function and the effect of various resuscitation and de-resuscitation strategies on the course and outcome of AKI.Peer reviewe

    Children's suggestibility in relation to their understanding about sources of knowledge

    In the experiments reported here, children chose either to maintain their initial belief about an object's identity or to accept the experimenter's contradicting suggestion. Both 3– to 4–year–olds and 4– to 5–year–olds were good at accepting the suggestion only when the experimenter was better informed than they were (implicit source monitoring). They were less accurate at recalling both their own and the experimenter's information access (explicit recall of experience), though they performed well above chance. Children were least accurate at reporting whether their final belief was based on what they were told or on what they experienced directly (explicit source monitoring). Contrasting results emerged when children decided between contradictory suggestions from two differentially informed adults: Three– to 4–year–olds were more accurate at reporting the knowledge source of the adult they believed than at deciding which suggestion was reliable. Decision making in this observation task may require reflective understanding akin to that required for explicit source judgments when the child participates in the task

    Delayed self-recognition in children with autism spectrum disorder.

    This study aimed to investigate temporally extended self-awareness (awareness of one’s place in and continued existence through time) in autism spectrum disorder (ASD), using the delayed self-recognition (DSR) paradigm (Povinelli et al., Child Development 67:1540–1554, 1996). Relative to age and verbal ability matched comparison children, children with ASD showed unattenuated performance on the DSR task, despite showing significant impairments in theory-of-mind task performance, and a reduced propensity to use personal pronouns to refer to themselves. The results may indicate intact temporally extended self-awareness in ASD. However, it may be that the DSR task is not an unambiguous measure of temporally extended self-awareness and it can be passed through strategies which do not require the possession of a temporally extended self-concept

    Transmission-dominated mid-infrared supermirrors with finesse exceeding 200 000

    We fabricate and characterize substrate-transferred single-crystal mirror coatings with 9.33 ±\pm 0.17 ppm of transmittance and 4.27 ±\pm 0.52 ppm of excess optical loss, corresponding to a transmission-loss dominated reflectance of 99.9986% at 4.45 μ\mum. For the first time, a cavity finesse > 200 000 is achieved in the mid-infrared.Comment: Sept 21: Minor revisions to conform to 2-page length requirement including abbr. refs.; Figure font sizes increase

    Is It Rational to Assume that Infants Imitate Rationally? A Theoretical Analysis and Critique

    Get PDF
    It has been suggested that preverbal infants evaluate the efficiency of others' actions (by applying a principle of rational action) and that they imitate others' actions rationally. The present contribution presents a conceptual analysis of the claim that preverbal infants imitate rationally. It shows that this ability rests on at least three assumptions: that infants are able to perceive others' action capabilities, that infants reason about and conceptually represent their own bodies, and that infants are able to think counterfactually. It is argued that none of these three abilities is in place during infancy. Furthermore, it is shown that the idea of a principle of rational action suffers from two fallacies. As a consequence, is it suggested that it is not rational to assume that infants imitate rationally. Copyright (C) 2012 S. Karger AG, Base

    Impaired Competence for Pretense in Children with Autism: Exploring Potential Cognitive Predictors.

    Get PDF
    Lack of pretense in children with autism has been explained by a number of theoretical explanations, including impaired mentalising, impaired response inhibition, and weak central coherence. This study aimed to empirically test each of these theories. Children with autism (n=60) were significantly impaired relative to controls (n=65) when interpreting pretense, thereby supporting a competence deficit hypothesis. They also showed impaired mentalising and response inhibition, but superior local processing indicating weak central coherence. Regression analyses revealed that mentalising significantly and independently predicted pretense. The results are interpreted as supporting the impaired mentalising theory and evidence against competing theories invoking impaired response inhibition or a local processing bias. The results of this study have important implications for treatment and intervention
