Final report of the social pedagogy pilot programme: development and implementation

In 2008, the government commissioned Thomas Coram Research Unit, Institute of Education University of London to develop and implement a pilot programme in order to determine the impact of, and best method for, introducing a social pedagogic approach in residential children’s homes in line with the Care Matters White Paper’s commitment (DCSF 2007). The intentions were modest - to make some ‘ripples’ in the world of residential childcare. This report is of the development and implementation part of the pilot programme. There are around 2,000 children’s homes in England, run by private for profit, independent and public sector employers and around 6,500 young people are in residence at any one time (SFR 2009). Since 2002, children’s homes, as with other services for children, have been regulated by, and inspected against, national minimum standards, which, although not intended to be a benchmark of practice, or representing standardisation of provision (DH 2002), arguably implied just that. Clough, Bullock and Ward (2006) viewed the requirement to meet bureaucratic standards as risking the undervaluing of important and complex issues of quality and process. It was in this context that the pilot programme took place. As an established tradition in continental Europe, social pedagogy is often understood as ‘education in its broadest sense’ (Petrie et al. 2009) - an educational approach to social issues. Its breadth can be seen in its concern for the whole person as emotional, thinking and physical beings, promoting their active engagement in decisions about their own lives and as members of society. It is a discipline that takes account of the complexity of different social contexts. In continental European countries social pedagogues typically have a bachelor’s degree, combining academic knowledge, with practical, organisational and communication skills and often, the expressive arts and/or outdoor adventure/ environmental activities. Social pedagogues working in residential care in continental European countries expect to exercise a range of responsibilities both inward looking to the home itself and outward looking to the interface between the children’s home and the wider society to which the young person belongs. The pilot programme was designed around three groups of children’s homes or ‘pilot sites’ with differing social pedagogic input, ranging from social pedagogues trained overseas but working to residential care worker job titles, to social pedagogues working to social pedagogue job titles with, in addition, part of their time devoted to training and awareness raising activities. Children’s homes were selected for their stated support of the programme objectives and their willingness to learn about social pedagogy from the social pedagogues. Forty eight social pedagogues were recruited through employer’s recruitment procedures although some left before the end of the programme period

Development of scenarios for land cover, population density, impervious cover, and conservation in New Hampshire, 2010–2100

Future changes in ecosystem services will depend heavily on changes in land cover and land use, which, in turn, are shaped by human activities. Given the challenges of predicting long-term changes in human behaviors and activities, scenarios provide a framework for simulating the long-term consequences of land-cover change on ecosystem function. As input for process-based models of terrestrial and aquatic ecosystem function, we developed scenarios for land cover, population density, and impervious cover for the state of New Hampshire for 2020–2100. Key drivers of change were identified through information gathered from six sources: historical trends, existing plans relating to New Hampshire’s land-cover future, surveys, existing population scenarios, key informant interviews with diverse stakeholders, and input from subject-matter experts. Scenarios were developed in parallel with information gathering, with details added iteratively as new questions emerged. The final scenarios span a continuum from spatially dispersed development with a low value placed on ecosystem services (Backyard Amenities) to concentrated development with a high value placed on ecosystem services (the Community Amenities family). The Community family includes two population scenarios (Large Community and Small Community), to be combined with two scenarios for land cover (Protection of Wildlands and Promotion of Local Food), producing combinations that bring the total number of scenarios to six. Between Backyard Amenities and Community Amenities is a scenario based on linear extrapolations of current trends (Linear Trends). Custom models were used to simulate decadal change in land cover, population density, and impervious cover. We present raster maps and proportion of impervious cover for HUC10 watersheds under each scenario and discuss the trade-offs of our translation and modeling approach within the context of contemporary scenario projects

High-Resolution Identification of Multiple Salmonella Serovars in a Single Sample by Using CRISPR-SeroSeq

Salmonella enterica is represented by \u3e2,600 serovars that can differ in routes of transmission, host colonization, and in resistance to antimicrobials. S. enterica is the leading bacterial cause of foodborne illness in the United States, with well-established detection methodology. Current surveillance protocols rely on the characterization of a few colonies to represent an entire sample; thus, minority serovars remain undetected. Salmonella contains two CRISPR loci, CRISPR1 and CRISPR2, and the spacer contents of these can be considered serovar specific. We exploited this property to develop an amplicon-based and multiplexed sequencing approach, CRISPR-SeroSeq (serotyping by sequencing of the CRISPR loci), to identify multiple serovars present in a single sample. Using mixed genomic DNA from two Salmonella serovars, we were able to confidently detect a serovar that constituted 0.01% of the sample. Poultry is a major reservoir of Salmonella spp., including serovars that are frequently associated with human illness, as well as those that are not. Numerous studies have examined the prevalence and diversity of Salmonella spp. in poultry, though these studies were limited to culture-based approaches and therefore only identified abundant serovars. CRISPR-SeroSeq was used to investigate samples from broiler houses and a processing facility. Ninety-one percent of samples harbored multiple serovars, and there was one sample in which four different serovars were detected. In another sample, reads for the minority serovar comprised 0.003% of the total number of Salmonella spacer reads. The most abundant serovars identified were Salmonella enterica serovars Montevideo, Kentucky, Enteritidis, and Typhimurium. CRISPR-SeroSeq also differentiated between multiple strains of some serovars. This high resolution of serovar populations has the potential to be utilized as a powerful tool in the surveillance of Salmonella species

Crystallographic and Compositional Dependence of Thermodynamic Stability of [Co(II), Cu(II), and Zn(II)] in 2-Methylimidazole-Containing Zeolitic Imidazolate Frameworks.

We report the first systematic study experimentally investigating the effect of changes to the divalent metal node on the thermodynamic stability of three-dimensional (3D) and two-dimensional (2D) zeolitic imidazolate frameworks (ZIFs) based on 2-methylimidazolate linkers. In particular, the comparison of enthalpies of formation for materials based on cobalt, copper, and zinc suggests that the use of nodes with larger ionic radius metals leads to the stabilization of the porous sodalite topology with respect to the corresponding higher-density diamondoid (dia)-topology polymorphs. The stabilizing effect of metals is dependent on the framework topology and dimensionality. With previous works pointing to solvent-mediated transformation of 2D ZIF-L structures to their 3D analogues in the sodalite topology, thermodynamic measurements show that contrary to popular belief, the 2D frameworks are energetically stable, thus shedding light on the energetic landscape of these materials. Additionally, the calorimetric data confirm that a change in the dimensionality (3D → 2D) and the presence of structural water within the framework can stabilize structures by as much as 40 kJ·mol-1, making the formation of zinc-based ZIF-L material under such conditions thermodynamically preferred to the formation of both ZIF-8 and its dense, dia-topology polymorph

Experimental Investigation of Thermodynamic Stabilization in Boron Imidazolate Frameworks (BIFs) Synthesized by Mechanochemistry.

This study experimentally explores the energetics for the formation of boron-imidazolate frameworks (BIFs), which are synthesized by mechanochemistry. The topologically similar frameworks employ the same tetratopic linker based on tetrakis(imidazolyl)boric acid but differ in the monovalent cation metal nodes. This permits assessment of the stabilizing effect of metal nodes in frameworks with sodalite (SOD) and diamondoid (dia) topologies. The enthalpy of formation from endmembers (metal oxide and linker), which define thermodynamic stability of the structures, has been determined by use of acid solution calorimetry. The results show that heavier metal atoms in the node promote greater energetic stabilization of denser structures. Overall, in BIFs the relation between cation descriptors (ionic radius and electronegativity) and thermodynamic stability depends on framework topology. Thermodynamic stability increases with the metallic character of the cation employed as the metal node, independent of the framework topology. The results suggest unifying aspects for thermodynamic stabilization across MOF systems

Structure and properties evolution with inorganic and organic acids of a new organo-chlorocadmate compound (C6H20N3)2[Cd2Cl10] : theoretical approach

This work was supported by the Ministry of Higher Education and Scientific Research of Tunisia.This work describes the theoretical studies of the reactivity, electrical and thermodynamic properties of a novel organo-chlorocadmate complex (C6H20N3)2[Cd2Cl10] and its inorganic and organic acid derivatives. The synthesis and crystal structure are described, with the compound crystallizing in the orthorhombic (Pnma) space group with unit cell parameters: a = 7.25494(11) Å, b = 29.3000(5) Å, c = 7.33927(13) Å. The semi-empirical calculations reveal that not only are all of the derivatives semiconductors, but also that the inclusion of acids in the structure alter the electrical and thermodynamic properties significantly, demonstrating a systematic and easy method for tuning the materials reactivity along with other desirable properties.PostprintPeer reviewe

The Mechanism behind Erosive Bursts in Porous Media

Erosion and deposition during flow through porous media can lead to large erosive bursts that manifest as jumps in permeability and pressure loss. Here we reveal that the cause of these bursts is the re-opening of clogged pores when the pressure difference between two opposite sites of the pore surpasses a certain threshold. We perform numerical simulations of flow through porous media and compare our predictions to experimental results, recovering with excellent agreement shape and power-law distribution of pressure loss jumps, and the behavior of the permeability jumps as function of particle concentration. Furthermore, we find that erosive bursts only occur for pressure gradient thresholds within the range of two critical values, independent on how the flow is driven. Our findings provide a better understanding of sudden sand production in oil wells and breakthrough in filtration.Comment: 7 pages, 8 figure

Dogs Produce Distinctive Play Pants: Confirming Simonet

Vocalizations in expressive, nonhuman animals can explain the evolution of human communication. A domain-specific play pant in dogs can signify a comparison to human laughter and can explain the development of interspecies empathy through social contagion. A prescreening survey captured demographic information about the guardian and the dog. Accepted pairs wore wireless microphones, transmitters, and a harness, while a camera captured video. Independent raters analyzed audio and video recordings across training, play and shared rest interactions via an ethogram and RavenLite. There is evidence that dogs produce a play pant. When interacting with their guardians, dogs produced more vocalizations during play than in training or shared rest. A one-way ANOVA resulted in significant differences regarding the presence of vocalizations during the three interactions (F2,39 = 5.897, p = 0.006). While a Tukey post hoc test revealed that fewer play pants were observed during training (0.875 ± 1.30 min, p = 0.018) and shared rest (0.875 ± 1.60 min, p = 0.013) as compared to play interactions (20.63 ± 29.14 min). By validating the canine play pant, our work is among the first to explore the evolution of laughter as a signal between species
