Determination of Critical Separation Distance Between Dwellings in Informal Settlements Fire
Authors: Wang Yu , Gibson Lesley , Beshir Mohamed , Rush David 
Published: January 2021

AbstractApproximately one billion people across the globe are living in informal settlements with a large potential fire risk. Due to the high dwelling density, a single informal settlement dwelling fire may result in a very serious fire disaster leaving thousands of people homeless. In this work, a simple physics-based theoretical model was employed to assess the critical fire separation distance between dwellings. The heat flux and ejected flame length were obtained from a full-scale dwelling tests with ISO 9705 dimension (3.6 m × 2.4 m × 2.4 m) to estimate the radiation decay coefficient of the radiation heat flux away from the open door. The ignition potential of combustible materials in adjacent dwellings are analyzed based on the critical heat flux from cone calorimeter tests. To verify the critical distance in real informal settlement fire, a parallel method using aerial photography within geographic information systems (GIS), was employed to determine the critical separation distances in four real informal settlement fires of 2014–2015 in Masiphumelele, Cape Town, South Africa. The fire-spread distances were obtained as well through the real fires. The probabilistic analysis was conducted by Weibull distribution and logistic regression, and the corresponding separation distances were given with different fire spread probabilities. From the experiments with the assumption of no interventions and open doors and windows, it was established that the heat flux would decay from around 36 kW/m2 within a distance of 1.0 m to a value smaller than 5 kW/m2 at a distance of 4.0 m. Both experiments and GIS results agree well and suggest the ignition probabilities at distances of 1.0 m, 2.0 m and 3.0 m are 97%, 52% and 5% respectively. While wind is not explicitly considered in the work, it is implicit within the GIS analyses of fire spread risk, therefore, it is reasonable to say that there is a relatively low fire spread risk at distances greater than 3 m. The distance of 1.0 m in GIS is verified to well and conservatively predict the fire spread risk in the informal settlements.
Into the Contact Zones of Heritage Diplomacy: Local Realities, Transnational Themes and International Expectations
Authors: Chalcraft Jasper 
Published: January 2021

AbstractHeritage is increasingly promoted as a tool for economic and social development to help rebuild societies that have suffered conflict and deep social trauma. Heritage diplomacy is an emergent form of cultural relations that forms a ‘contact zone’ between different stakeholders and divergent expectations. This paper explores some aspects of this field of heritage diplomacy and develops a basic typology by contrasting the tension between the uses of ‘charismatic heritage diplomacy’ and more ‘careful heritage diplomacy’. It examines differences between local realities and international expectations of heritage by bringing together two case studies: one from a Creative Europe–funded project where civil society actors develop strategies for working with the difficult heritage that lies behind nationalist myths, and the other from a British Council–funded programme dealing with endangered heritage in the MENA region. Critical studies of heritage-making often pitch the local against the international, with grassroot activities contrasted with international rhetoric surrounding heritage places, objects and practices. However, this dichotomy can mask other actors and social dynamics, not least the subtleties of how the collective traumas of conflict play out in the cultural field. The idea of heritage diplomacy as a ‘contact zone’ (Clifford 1997) highlights that heritage-making in (post-)conflict cultural relations is an ontological encounter between international agents and the traumatised communities for whom the stakes are, inevitably, higher. Mediated through the transnational best practices of heritage professionals, and through the visible pragmatism of civil society heritage activists, the impacts of heritage-making nevertheless remain complicated and entangled.
Personalized Goals for Positive Behavioral Support: Engaging Directly with Children who have Intellectual and Developmental Disabilities
Authors: Gore Nick James , McGill Peter , Hastings Richard Patrick 
Published: January 2021

AbstractStakeholder involvement is fundamental to Positive Behavioral Support yet research in this area rarely obtains views of children with Intellectual and Developmental Disabilities. This study aimed to develop and demonstrate a means of engaging directly with children to identify personalized goals and priorities for their future support. An augmented communication approach was used to facilitate interviews with children who had a range of disabilities and displayed behavior that challenges. The interviewer asked children about activities, their own behavior, a caregiver’s behavior, and quality of life to focus future potential assessment and intervention. We completed interviews in at least some areas with 9 out of 14 children. Children prioritized goals for future support and evidenced insight into behavior, needs, and preferences. These findings have promising implications for further direct engagement of children with disabilities throughout a support pathway to achieve outcomes rich in social validity.

AbstractInfluenza is a potential cause of severe disease in the immunocompromised. Patients with hypogammaglobulinemia, in spite of adequate replacement therapy, are at risk of significant morbidity and adverse outcomes. A seasonal vaccine is the primary prophylactic countermeasure to limit disease. The aim of this study was to evaluate the attitude, knowledge, and influenza vaccine uptake among Irish patients receiving immunoglobulin replacement therapy (IgRT), as well as uptake in co-habitants. Fifty-seven percent of patients receiving IgRT at a regional immunology referral center completed a questionnaire evaluation. Seventy-six percent of IgRT patients received the influenza vaccine for the 2019 season. Ninety-eight percent recognized that influenza could be prevented with vaccination, and 81% deemed it a safe treatment. Ninety-three percent correctly identified that having a chronic medical condition, independent of age, was an indication for vaccination. Despite excellent compliance and knowledge, many were not aware that vaccination was recommended for co-habitants, and only 24% had full vaccine coverage at home. Those who received advice regarding vaccination of household members had higher rates of uptake at home. This study demonstrates awareness and adherence to seasonal influenza vaccine recommendations among patients receiving IgRT. Over three quarters felt adequately informed, the majority stating physicians as their information source. We identified an easily modifiable knowledge gap regarding vaccination of household members. This data reveals a need to emphasize the importance of vaccination for close contacts of at-risk patients, to maintain optimal immunity and health outcome.
Identifying and Responding to the Complex Needs of Domestic Violence Housing Practitioners at the Onset of the COVID-19 Pandemic

Published: January 2021

AbstractThe social, financial, and emotional repercussions of the COVID-19 pandemic has left many organizations that support survivors of intimate partner violence questioning how to maintain core services while addressing compounding individual, organizational, and public health issues. Stay-at-home orders and other COVID-19 mitigation strategies have resulted in reduced shelter availability and increased intimate partner violence rates. Coupled with the economic impact of the pandemic, these factors have threatened financial and housing stability. To better understand these challenges and provide immediate support, The National Alliance for Safe Housing (NASH) co-hosted a peer support call to provide a virtual platform for practitioners to ask questions, discuss challenges, and share strategies for quality service provision during the COVID-19 pandemic. Over 800 practitioners from across the United States participated in the NASH call, most of whom were advocates, program directors, and managers. NASH gathered data on practitioners’ needs from a brief survey from the registration form analyzed using conventional inductive content analysis. Practitioners’ primary concerns were situated within eight questions, which we categorized into four meta-categories: (1) managing residential housing programs; (2) getting survivors materials resources; (3) keeping staff safe; and (4) maintaining organizational operations. The paper concludes with community-grounded and empirically supported practice recommendations aligned with practitioners’ expressed needs.

AbstractThe releasing of transgenic soybeans (Glycine max (L.) Merr.) into farming systems raises concerns that transgenes might escape from the soybeans via pollen into their endemic wild relatives, the wild soybean (Glycine soja Sieb. et Zucc.). The fitness of F1 hybrids obtained from 10 wild soybean populations collected from China and transgenic glyphosate-resistant soybean was measured without weed competition, as well as one JLBC-1 F1 hybrid under weed competition. All crossed seeds emerged at a lower rate from 13.33–63.33%. Compared with those of their wild progenitors, most F1 hybrids were shorter, smaller, and with decreased aboveground dry biomass, pod number, and 100-seed weight. All F1 hybrids had lower pollen viability and filled seeds per plant. Finally, the composite fitness of nine F1 hybrids was significantly lower. One exceptional F1 hybrid was IMBT F1, in which the composite fitness was 1.28, which was similar to that of its wild progenitor due to the similarities in pod number, increased aboveground dry biomass, and 100-seed weight. Under weed competition, plant height, aboveground dry biomass, pod number per plant, filled seed number per plant, and 100-seed weight of JLBC-1 F1 were lower than those of the wild progenitor JLBC-1. JLBC-1 F1 hybrids produced 60 filled seeds per plant. Therefore, F1 hybrids could emerge and produce offspring. Thus, effective measures should be taken to prevent gene flow from transgenic soybean to wild soybean to avoid the production F1 hybrids when releasing transgenic soybean in fields in the future.
Variation of pectineus muscle forming a hiatus
Authors: Kim Hankyu , Nam Yong Seok 
Published: January 2021

AbstractKnowledge of the anatomic variations in the pectineus muscle is important for vascular surgeons to minimize complications following surgical approach to the distal part of the deep femoral artery. During routine dissection of the thigh, variations in the bilateral pectineus muscles were identified in an 82-year-old male cadaver. On both sides, the superficial and deep layers of the pectineus were divided at its distal part, forming a triangular-shaped hiatus between them and the femur shaft. Distally, the tendon of the superficial part intermingled with the tendon of the adductor longus. The tendon of the deep part was inserted into the pectineal line. On the right side, the deep femoral artery and its first perforating artery passed through the hiatus. On the left side, the deep femoral artery pierced the hiatus, and then, the first perforating artery was branched from the deep femoral artery. No reported case has described a pectineal hiatus. The variations observed in this study are an ontogenetic vestige of the two different origins of the pectineus. The insertion of the superficial layer into the adductor longus tendon suggests a close relationship between these muscles during prenatal development. Surgeons should be aware of the variation to minimize injury to the pectineus muscle while approaching the deep femoral artery.
Natural kind terms again
Authors: Raatikainen Panu 
Published: January 2021

AbstractThe new externalist picture of natural kind terms due to Kripke, Putnam, and others has become quite popular in philosophy. Many philosophers of science have remained sceptical. Häggqvist and Wikforss have recently criticised this view severely. They contend it depends essentially on a micro-essentialist view of natural kinds that is widely rejected among philosophers of science, and that a scientifically reasonable metaphysics entails the resurrection of some version of descriptivism. It is argued in this paper that the situation is not quite as dark for the new theory of reference as many critics suggest. There are several distinct questions here which should not be conflated and ought to be dealt with one by one. Descriptivism remains arguably problematic.

Abstract
Embedding thread lift rhytidectomy, also known as “thread lifting” in China, with the natures of simple operation, less trauma and quick recovery, is progressively used in clinical practice as a new technology of face lifting. Herewith, a brief introduction of the previous advances of thread lifting techniques and materials in the facial beauty industry, combined with the discussion on various types of sutures, common complications, and the site of actions were provided. The main limitations of present thread lifting material include: (1) the use of non-absorbable sutures is liable to cause allergies and a series of complications; (2) the absorbable sutures are easily degradation, and people need to reshape in a relatively short period. Therefore, the high biocompatible spider silk was proposed as a novel material of thread lifting suture and related devices, the advantages and preliminary achievements on spider silk were also addressed.

Authors: FERREIRA FERNANDO 
Published: January 2021

AbstractIt is well-known that an element of a commutative ring with identity is nilpotent if, and only if , it lies in every prime ideal of the ring. A modification of this fact is amenable to a very simple proof mining analysis. We formulate a quantitative version of this modification and obtain an explicit bound. We present an application. This proof mining analysis is theleitmotiffor some comments and observations on the methodology of computational extraction. In particular, we emphasize that the formulation of quantitative versions of ordinary mathematical theorems is ofindependent interestfrom proof mining metatheorems.

AbstractObjective:A Canadian health authority implemented a multisectoral intervention designed to control severe acute respiratory coronavirus virus 2 (SARS-CoV-2) transmission during long-term care facility (LTCF) outbreaks. The primary objective was to evaluate the effectiveness of the intervention 14 days after implementation.Design:Quasi-experimental, segmented regression analysis.Intervention:A series of outbreak measures classified into 4 categories: case and contact management, proactive case detection, rigorous infection control practices and resource prioritization and stewardship.Methods:A mixed-effects segmented Poisson regression model was fitted to the incidence rate of coronavirus disease 2019 (COVID-19), calculated every 2 days, within each facility and case type (staff vs residents). For each facility, the outbreak time period was segmented into an early outbreak period (within 14 days of the intervention) and postintervention period (beyond 14 days following the intervention). Model outputs quantified COVID-19 incidence trend and rate changes between these 2 periods. A secondary model was constructed to identify effect modification by case type.Results:The significant upward trend in COVID-19 incidence rate during the early outbreak period (rate ratio [RR], 1.07; 95% confidence interval [CI], 1.03–1.11; P < .001) reversed during the postintervention period (RR, 0.73; 95% CI, 0.67–0.80; P < .001). The average trend did not differ by case type during the early outbreak period (P > .05) or the postintervention period (P > .05). However, staff had a 70% larger decrease in the average rate of COVID-19 during the postintervention period than residents (RR, 0.30; 95% CI, 0.10–0.88; P < .05).Conclusions:Our study provides evidence for the effectiveness of this intervention to reduce the transmission of COVID-19 in LTCFs. This intervention can be adapted and utilized by other jurisdictions to protect the vulnerable individuals in LTCFs.
A Permutation-Based Changepoint Technique for Monitoring Effect Sizes
Authors: Kent Daniel , Wilson James D. , Cranmer Skyler J. 
Published: January 2021

AbstractAcross the social sciences, scholars regularly pool effects over substantial periods of time, a practice that produces faulty inferences if the underlying data generating process is dynamic. To help researchers better perform principled analyses of time-varying processes, we develop a two-stage procedure based upon techniques for permutation testing and statistical process monitoring. Given time series cross-sectional data, we break the role of time through permutation inference and produce a null distribution that reflects a time-invariant data generating process. The null distribution then serves as a stable reference point, enabling the detection of effect changepoints. In Monte Carlo simulations, our randomization technique outperforms alternatives for changepoint analysis. A particular benefit of our method is that, by establishing the bounds for time-invariant effects before interacting with actual estimates, it is able to differentiate stochastic fluctuations from genuine changes. We demonstrate the method’s utility by applying it to a popular study on the relationship between alliances and the initiation of militarized interstate disputes. The example illustrates how the technique can help researchers make inferences about where changes occur in dynamic relationships and ask important questions about such changes.

The use of tonal coarticulation in segmentation of artificial language speech: A study with Mandarin listeners
Authors: Guo Zhe-Chen , Ou Shu-Chen 
Published: January 2021

AbstractTonal carryover assimilation, whereby a tone is assimilated to the preceding one, is conditioned by prosodic boundaries in a way suggesting that its presence may signal continuity or lack of a boundary. Its possibility as a speech segmentation cue was investigated in two artificial language (AL) learning experiments. Mandarin-speaking listeners identified the “words” of a three-tone AL (e.g., [pé.tī.kù]) after listening to six long speech streams in which the words were repeated continuously without pauses. The first experiment revealed that segmentation was disrupted in an “incongruent-cues” condition where tonal carryover assimilation occurred across AL word boundaries and conflicted with statistical regularities in the speech streams. Segmentation was neither facilitated nor inhibited in a “congruent-cues” condition where tonal carryover assimilation occurred only within the AL words in 27% of the repetitions and never across word boundaries. A null effect was again found for the congruent-cues condition of the second experiment, where all AL word repetitions carried tonal carryover assimilation. These findings show that tonal carryover assimilation is exploited to resolve segmentation problems when cues conflict. Its null effect in the congruent-cues conditions might be linked to cue redundancy and suggest that it is weighted low in the segmentation cue hierarchy.

AbstractWith the progress in science and technology, hazardous chemicals are becoming more essential in chemical products, industrial and agricultural production, and daily life. Hazardous chemicals have poisoning, corrosive, explosive, and combusting natures; once on fire, they can trigger a chain of catastrophic incidences, resulting in casualties, property loss, and environmental pollution and posing hazards to life and property. Using the “8–12” explosion of the Ruihai Logistics warehouse in Tianjin Port (Binhai New District, China), the present study analyzes the characteristics of trauma of the casualties in this accident and the emergency medical rescue strategies. The goals were to improve the ability of emergency rescue in such accidents and to save people’s lives and property to the maximum extent.
Indiana Court Denies Pharmaceutical's Claim Under Blood Shield Act
Authors: J.P.D.  
Published: January 2021

The Indiana Court of Appeals, in JKB, Sr. v. Armour Pharmaceutical Co. (No. 49A029506CV341, 1996 WL 22708 (Ind. Ct. App. Jan. 24, 1996)), held that the state's Blood Shield Act does not protect pharmaceutical companies that produce blood-derived products from product liability suits based on injuries attributable to tainted blood supplies. Blood shield statutes help to guarantee adequate blood supplies by limiting the liability of blood banks. This holding limits the defenses available to pharmaceutical companies sued under product liability theory.The defendant, Armour Pharmaceutical, produces and sells clotting factor agents, which are derived through plasmapheresis. Plasmapheresis is a costly and complex donation process through which the plasma and red blood cells of a donor's blood are separated. After separation, the process returns the red blood cells to the donor but retains the plasma.
