Understanding Doubly Center-Embedded Sentences Through Contrastive Focus

A production and comprehension-judgment experiment examined the relationship between prosody and comprehensibility in doubly center-embedded relative clause constructions in English. Lexically identical sentences with contrastive emphasis on NP1, NP2, or VP1, and a baseline version for comparison, were read aloud for recording and judged for comprehensibility. Contrast on NP2 and VP1 yielded higher comprehensibility judgments compared to baseline than contrast on NP1 compared to baseline. This was contrary to the prediction that contrast on NP1 would encourage the prosodic pattern NP1 || RC || VP3, which in previous work has been reported to be optimal for comprehension. Several explanations for this outcome are considered, including the possibility that contrastive focus does not reliably induce a following prosodic boundary if phrase lengths are not supportive of it

Manipulating TLR signaling increases the anti-tumor T Cell response induced by viral cancer therapies

The immune response plays a key role in enhancing the therapeutic activity of oncolytic virotherapies. However, to date, investigators have relied on inherent interactions between the virus and the immune system, often coupled to the expression of a single cytokine transgene. Recently, the importance of TLR activation in mediating adaptive immunity has been demonstrated. We therefore sought to influence the type and level of immune response raised after oncolytic vaccinia therapy through manipulation of TLR signaling. Vaccinia naturally activates TLR2, associated with an antibody response, whereas a CTL response is associated with TLR3-TRIF-signaling pathways. We manipulated TLR signaling by vaccinia through deglycosylation of the viral particle to block TLR2 activation and expression of a TRIF transgene. The resulting vector displayed greatly reduced production of anti-viral neutralizing antibody as well as an increased anti-tumor CTL response. Delivery in both naive and pre-treated mice was enhanced and immunotherapeutic activity dramatically improved

Utilisation of chimeric lyssaviruses to assess vaccine protection against highly divergent lyssaviruses

Lyssaviruses constitute a diverse range of viruses with the ability to cause fatal encephalitis known as rabies. Existing human rabies vaccines and post exposure prophylaxes (PEP) are based on inactivated preparations of, and neutralising antibody preparations directed against, classical rabies viruses, respectively. Whilst these prophylaxes are highly efficient at neutralising and preventing a productive infection with rabies virus, their ability to neutralise other lyssaviruses is thought to be limited. The remaining 15 virus species within the lyssavirus genus have been divided into at least three phylogroups that generally predict vaccine protection. Existing rabies vaccines afford protection against phylogroup I viruses but offer little to no protection against phylogroup II and III viruses. As such, work involving sharps with phylogroup II and III must be considered of high risk as no PEP is thought to have any effect on the prevention of a productive infection with these lyssaviruses. Whilst rabies virus itself has been characterised in a number of different animal models, data on the remaining lyssaviruses are scarce. As the lyssavirus glycoprotein is considered to be the sole target of neutralising antibodies we generated a vaccine strain of rabies using reverse genetics expressing highly divergent glycoproteins of West Caucasian Bat lyssavirus and Ikoma lyssavirus. Using these recombinants, we propose that recombinant vaccine strain derived lyssaviruses containing heterologous glycoproteins may be a suitable surrogate for wildtype viruses when assessing vaccine protection for the lyssaviruses

Overview of the BlockNormal Event Trigger Generator

In the search for unmodeled gravitational wave bursts, there are a variety of methods that have been proposed to generate candidate events from time series data. Block Normal is a method of identifying candidate events by searching for places in the data stream where the characteristic statistics of the data change. These change-points divide the data into blocks in which the characteristics of the block are stationary. Blocks in which these characteristics are inconsistent with the long term characteristic statistics are marked as Event-Triggers which can then be investigated by a more computationally demanding multi-detector analysis.Comment: GWDAW-8 proceedings, 6 pages, 2 figure

Recognising barriers to implementation of Blue-Green infrastructure: a Newcastle case study

There is a recognised need for a fundamental change in how the UK manages urban water and flood risk in response to increasingly frequent rainfall events coupled with planned urban expansion. Approaches centred on ‘living with and making space for water’ are increasingly adopted internationally. Nonetheless, widespread implementation of Blue-Green infrastructure (BGI) is currently hampered by barriers that impede uptake and innovation. We investigate the barriers to implementation of BGI in Newcastle, UK, through a series of semi-structured interviews with professional stakeholders. We identify and categorise 17 types of barrier and identify targeted strategies to overcome the dominant barriers. We recommend promotion of BGI’s capacity to meet the objectives of multiple organisations and Local Authority departments, in addition to managing urban water. We conclude that strong business cases, supported by monetised evidence of benefits, and collaborative, inter-agency working could advance implementation of BGI within the current flood risk management legislation

Long-term effects of allergen sensitization and exposure in adult asthma: a prospective study.

BACKGROUND: : We investigated the effects of sensitization and exposure to common domestic allergens on longitudinal changes in lung function and bronchial hyperresponsiveness. METHODS: : Subjects attended 2 visits that were 4 years apart. Skin prick testing was performed and household dust samples were collected for quantification of mite, dog, and cat allergens at baseline. Measurements of lung function, exhaled nitric oxide, and bronchial hyperresponsiveness were completed at both visits. RESULTS: : Dust samples were collected in 165 of the 200 subjects completing both visits. Mean length of follow-up was 47 months. Bronchial hyperresponsiveness, measured at both visits in 86 subjects, deteriorated in those exposed to high mite allergen levels compared with those not exposed [mean (95% CI) doubling dose change PD20 = -0.44 (-1.07 to 0.19) vs 0.82 (0.27 to 1.36)], but improved in those exposed to high dog allergen levels compared with those not exposed [1.10 (0.33 to 1.86) vs 0.10 (-0.39 to 0.58)]. The associations were significant in the multivariate models. Cat allergen exposure was not associated with any changes in lung function, exhaled nitric oxide, or bronchial hyperresponsiveness. CONCLUSIONS: : In a 4-year prospective cohort of persons with asthma, exposure to high levels of dust mite allergens at baseline was associated with a subsequent increase in bronchial hyperresponsiveness

Learning and Action Alliance framework to facilitate stakeholder collaboration and social learning in urban flood risk management

Flood and water management governance may be enhanced through partnership working, intra- and cross-organisational collaborations, and wide stakeholder participation. Nonetheless, barriers associated with ineffective communication, fragmented responsibilities and ‘siloed thinking’ restrict open dialogue and discussion. The Learning and Action Alliance (LAA) framework may help overcome these barriers by enabling effective engagement through social learning, and facilitating targeted actions needed to deliver innovative solutions to environmental problems. By increasing the adaptive capacity of decision-makers and participants, social learning through LAAs may lead to concerted action and sustained processes of behavioural change. In this paper, we evaluate the LAA framework as a catalyst for change that supports collaborative working and facilitates transition to more sustainable flood risk management. We use a case study in Newcastle-upon-Tyne, UK, to demonstrate how the LAA framework brought together disparate City stakeholders to co-produce new knowledge, negotiate innovative actions and, ultimately, work towards implementing a new vision for sustainable urban flood risk management. The shared vision of Newcastle as a ‘Blue-Green City’ that emerged is founded on a strong platform for social learning which increased organisations’ and individuals’ capacities to manage differences in perspectives and behaviours, reframe knowledge, and make collective decisions based on negotiation and conflict resolution. Broad recommendations based on lessons learned from the Newcastle LAA are presented to aid other cities and regions in establishing and running social learning platforms

Aligning ancient and modern approaches to sustainable urban water management in China: Ningbo as a ‘Blue-Green City’ in the ‘Sponge City’ Campaign

Modern urban flood and water management emphasises holistic strategies that reduce flood risk while providing co- benefits to urban economies, societies and environments. The ‘Blue‐Green City’ concept provides a viable framework for putting this into practice. Ningbo, is a coastal city with high flood risk, whose history as a Chinese ‘water town’ demonstrates that approaches to water management implicit to the ‘Blue‐Green’ concept were practiced in ancient times, and lessons can be learned from these applications. Furthermore, recent launch of the ‘Sponge City’ campaign by China's National Government demonstrates the political will to implement sustainable flood and water management in ways consistent with the ‘Blue‐Green’ ideals. Selection of Ningbo for a pilot project presents the opportunity to integrate new ‘Sponge city’ approaches with ancient ‘Blue‐Green’ principles, within the contexts of both new urban development and retrofit. Reinventing traditional approaches to urban water management and governance offers the possibility of maintaining flood risk at acceptable levels without constraining urban growth in China and other countries experiencing rapid urban development

Acoustic measurement and morphological features of organic sediment deposits in combined sewer networks

The performance of sewer networks has important consequences from an environmental and social point of view. Poor functioning can result in flood risk and pollution at a large scale. Sediment deposits forming in sewer trunks might severely compromise the sewer line by affecting the flow field, reducing cross-sectional areas, and increasing roughness coefficients. In spite of numerous efforts, the morphological features of these depositional environments remain poorly understood. The interface between water and sediment remains inefficiently identified and the estimation of the stock of deposit is frequently inaccurate. In part, this is due to technical issues connected to difficulties in collecting accurate field measurements without disrupting existing morphologies. In this paper, results from an extensive field campaign are presented; during the campaign a new survey methodology based on acoustic techniques has been tested. Furthermore, a new algorithm for the detection of the soil-water interface, and therefore for the correct esteem of sediment stocks is proposed. Finally, results in regard to bed topography, and morphological features at two different field sites are presented and reveal that a large variability in bed forms is present along sewer networks
