An Evaluation of English Crown Courts with and without Special Measures Implemented in Section 28 of the Youth Justice and Criminal Evidence Act

This series of studies was the first to evaluate the effects of the Section 28 pilot study on the treatment of vulnerable child witnesses in English Crown Courts. Section 28 of the Youth Justice and Criminal Evidence Act implemented mandatory Ground Rules Hearings, during which the judge, lawyers, and intermediary (if applicable) discussed appropriate accommodations to be made for child witnesses, following which the cross-examination could be pre-recorded. Analyses examined 43 cases that implemented the special measures (‘Section 28’ cases) and 44 cases that did not implement the special measures (‘Non-Section 28’ cases) that took place between 2012 and 2016. Analyses revealed that children in the Section 28 cases experienced less systemic delay than their counterparts. In addition, the trial preparation in the Section 28 cases was more thorough and this was associated with less risky questioning in the cross-examinations. However, younger children experienced longer delays and had fewer accommodations made for them than older children, regardless of condition. Additional analyses demonstrated that the forensic interviews replaced the evidence-in-chief in most cases almost entirely, with prosecutors asking few substantive questions. In the Section 28 cases, defense lawyers used fewer suggestive questions and asked less complex questions than Non-Section 28 defense lawyers. However, both types of lawyers still predominantly asked option-posing questions. Regardless of condition, defense lawyers asked fewer suggestive questions than their counterparts in other common-law countries and they asked younger children less complex questions. Results indicate that, although the Section 28 pilot study has not fixed all of the existing problems, it has significantly reduced systemic delay and improved the treatment of child witnesses in Crown Courts and thus should be rolled out nationally. As well, regardless of condition, English lawyers and judges seem receptive to recent special measures and appear to be effectively implementing them.Cambridge International Trus

THE ROLE OF EPHEMERAL STRATIFICATION, ANOXIA, AND ENTRAINMENT IN MEDIATING SPATIOTEMPORAL TROPHIC STATE DYNAMICS IN A LAKE MICHIGAN DROWNED RIVER MOUTH SYSTEM (MONA LAKE, MI)

Mona Lake, MI (a drowned river mouth system) has become eutrophic as result of cultural eutrophication. The integrated monitoring effort and subsequent modeling (LAKE2K) reported on here has shifted the management focus to internal phosphorus loads (60 percent of annual load, 90 percent of load during the stratified and anoxic period) as a necessary precursor to trophic state change. Sediment phosphorus release can yield extreme elevations (\u3e 1 mgSRP/L) of bottom water soluble reactive phosphorus (SRP), with blooms of potentially toxic cyanobacteria (largely Microcystis) occurring annually. Such blooms are ascribable to stochastic mixing and phosphorus entrainment to the surface waters, with entrainment forces shown to be significant as a result of this lakes geographic proximity to large fetch events across Lake Michigan. Intrusion events from Lake Michigan are shown to strengthen stratification in Mona Lake, increasing hypolimnetic phosphorus accumulation prior to mixing events. Hypothetical phosphorus reduction strategies applied to the calibrated model indicate treatment of internal loading and a 25 percent reduction in external loading would allow Mona Lake to remain below 20 ug/L total phosphorus (eutrophic threshold)

Characters with autism spectrum disorder in fiction : where are the women and girls?

Purpose Fiction has the potential to dispel myths and helps improve public understanding and knowledge of the experiences of under-represented groups. Representing the diversity of the population allows individuals to feel included, connected with and understood by society. Whether women and girls with autism spectrum disorder (ASD) are adequately and accurately represented in fictional media is currently unknown. The paper aims to discuss this issue. Design/methodology/approach Internet and library searches were conducted to identify female characters with ASD in works of fiction. Examples of such works were selected for further discussion based on their accessibility, perceived historical and cultural significance and additional characteristics that made the work particularly meaningful. Findings The search highlighted a number of female characters with ASD across a range of media, including books, television, film, theatre and video games. Many were written by authors who had a diagnosis of the condition themselves, or other personal experience. Pieces largely portrayed characters with traits that are highly recognised within the academic literature. However, some also appeared to endorse outdated myths and stereotypes. Existing works appear to preferentially portray high functioning autistic women, with limited representation of those whom also have intellectual disability. Originality/value This is the first exploration of the depiction of ASD in females within fiction. There is a need for more works of fiction responsibly depicting females with ASD, as this can help reduce stigma, develop public awareness and recognition and increase representation

The impact of multiple interviews on the accuracy and narrative coherence of children’s memories

This study investigated the accuracy and narrative coherence of children’s accounts of a staged event across two interviews in comparison to a control condition to discern between the effects of repeated recall and delay between interviews. Seventy-six 8–11-year-olds took part in a first aid training session. Half of the children were randomly assigned to be interviewed using open-ended questions twice, one week after the event and five weeks after the event, whilst the other half were interviewed only once, five weeks after the event. Supporting the hypotheses, children reported more details over the course of two interviews than in a single interview either 1-week or 5-weeks after the event, and details that remained consistent across the two interviews were more accurate than reminisced details. The increased completeness of children’s accounts in two interviews was accompanied by an increase in the use of markers of causal-temporal connectedness. The hypothesis regarding the negative effect of delay on the accuracy of children’s testimony was partially supported, as details reported in the first, 1-week interview were more accurate than details in the single 5-week interview. Results demonstrate that multiple interviews can increase the narrative coherence of children’s testimony without decreasing their accuracy

Total correlations and mutual information

In quantum information theory it is generally accepted that quantum mutual information is an information-theoretic measure of total correlations of a bipartite quantum state. We argue that there exist quantum states for which quantum mutual information cannot be considered as a measure of total correlations. Moreover, for these states we propose a different way of quantifying total correlations.Comment: 6 pages, 3 figures, published versio

Pseudotemporal invitations: 6- to 9-year-old maltreated children’s tendency to misinterpret invitations referencing “time” as solely requesting conventional temporal information

Forensic interviewers ask children broad input-free recall questions about individual episodes in order to elicit complete narratives, often asking about “the first time,” “the last time,” and “one time.” An overlooked problem is that the word “time” is potentially ambiguous, referring both to a particular episode and to conventional temporal information. We examined 191 6-9-year-old maltreated children’s responses to questions about recent events varying the wording of the invitations, either asking children to “tell me about” or “tell me what happened” one time/the first time/the last time the child experienced recent recurrent events. Additionally, half of the children were asked a series of “when” questions about recurrent events before the invitations. Children were several times more likely to provide exclusively conventional temporal information to “tell me about” invitations compared to “tell me what happened” invitations, and asking “when” questions before the invitations increased children’s tendency to give exclusively conventional temporal information. Children who answered a higher proportion of “when” questions with conventional temporal information were also more likely to do so in response to the invitations. The results suggest that children may often fail to provide narrative information because they misinterpret invitations using the word “time.

Private quantum decoupling and secure disposal of information

Given a bipartite system, correlations between its subsystems can be understood as information that each one carries about the other. In order to give a model-independent description of secure information disposal, we propose the paradigm of private quantum decoupling, corresponding to locally reducing correlations in a given bipartite quantum state without transferring them to the environment. In this framework, the concept of private local randomness naturally arises as a resource, and total correlations get divided into eliminable and ineliminable ones. We prove upper and lower bounds on the amount of ineliminable correlations present in an arbitrary bipartite state, and show that, in tripartite pure states, ineliminable correlations satisfy a monogamy constraint, making apparent their quantum nature. A relation with entanglement theory is provided by showing that ineliminable correlations constitute an entanglement parameter. In the limit of infinitely many copies of the initial state provided, we compute the regularized ineliminable correlations to be measured by the coherent information, which is thus equipped with a new operational interpretation. In particular, our results imply that two subsystems can be privately decoupled if their joint state is separable.Comment: Child of 0807.3594 v2: minor changes v3: presentation improved, one figure added v4: extended version with a lot of discussions and examples v5: published versio

Monogamy of entanglement and other correlations

It has been observed by numerous authors that a quantum system being entangled with another one limits its possible entanglement with a third system: this has been dubbed the "monogamous nature of entanglement". In this paper we present a simple identity which captures the trade-off between entanglement and classical correlation, which can be used to derive rigorous monogamy relations. We also prove various other trade-offs of a monogamy nature for other entanglement measures and secret and total correlation measures.Comment: 7 pages, revtex

Dredging fundamentally reshapes the ecological significance of 3D terrain features for fish in estuarine seascapes

Context: Landscape modification alters the condition of ecosystems and the structure of terrain, with widespread impacts on biodiversity and ecosystem functioning. Seafloor dredging impacts a diversity of flora and fauna in many coastal landscapes, and these processes also transform three-dimensional terrain features. The potential ecological significance of these terrain changes in urban seascapes has, however, not been investigated. Objectives: We examined the effects of terrain variation on fish assemblages in 29 estuaries in eastern Australia, and tested whether dredging changes how fish associate with terrain features. Methods: We surveyed fish assemblages with baited remote underwater video stations and quantified terrain variation with nine complementary metrics (e.g. depth, aspect, curvature, slope, roughness), extracted from bathymetry maps created with multi-beam sonar. Results: Fish diversity and abundance were strongly linked to seafloor terrain in both natural and dredged estuaries, and were highest in shallow waters and near features with high curvature. Dredging, however, significantly altered the terrain of dredged estuaries and transformed the significance of terrain features for fish assemblages. Abundance and diversity switched from being correlated with lower roughness and steeper slopes in natural estuaries to being linked to features with higher roughness and gentler slopes in dredged estuaries. Conclusions: Contrasting fish-terrain relationships highlight previously unrecognised ecological impacts of dredging, but indicate that plasticity in terrain use might be characteristic of assemblages in urban landscapes. Incorporating terrain features into spatial conservation planning might help to improve management outcomes, but we suggest that different approaches would be needed in natural and modified landscapes

Seafloor Terrain Shapes the Three-dimensional Nursery Value of Mangrove and Seagrass Habitats

Mangroves and seagrasses are important nurseries for many marine species, and this function is linked to the complexity and context of these habitats in coastal seascapes. It is also connected to bathymetric features that influence habitat availability, and the accessibility of refuge habitats, but the significance of terrain variation for nursery function is unknown. To test whether seafloor terrain influences nursery function, we surveyed fish assemblages from mangrove and seagrass habitats in 29 estuaries in eastern Australia with unbaited underwater cameras and quantified the surrounding three-dimensional terrain with a set of complementary surface metrics (that is, depth, aspect, curvature, slope, roughness) applied to sonar-derived bathymetric maps. Terrain metrics explained variability in assemblages in both mangroves and seagrasses, with differing effects for the entire fish assemblage and nursery species composition, and between habitats. Higher depth, plan curvature (concavity or convexity) and roughness (backscatter) were negatively correlated with abundance and diversity in mangroves and positively linked to abundance and diversity in seagrass. Mangrove nursery species (6 species) were most abundant in forests adjacent to flats with concave holes, rough substrates and low-moderate depths, whereas seagrass nursery species (3 species) were most abundant in meadows adjacent to deep channels with soft mounds and ledges. These findings indicate that seafloor terrain influences nursery function and demonstrate contrasting effects of terrain variation in mangroves and seagrass. We suggest that incorporating three-dimensional terrain into coastal conservation and restoration plans could help to improve outcomes for fisheries management, but contrasting strategies might be needed for different nursery habitats
