Close enough? professional closeness and safe caring
In countries around the world, residential child care has been rocked by scandals of abuse of children and young people by the people who were supposed to be caring for them. In the UK, in particular, the reaction to these revelations has been to implement a raft of measures that seek to ensure that nothing of the same nature or scale might happen again. However, there can be tensions between the implementation of such measures and the developmental and emotional needs of children and young people in residential care. In this paper, we outline recent policy and legislative developments and address some of the issues which we see as important in attempting to strike a balance between safe caring and quality caring, between professional closeness and abusive practice

âA productive and happy collaborationâ: maximising impact through project design
This case study describes a highly collaborative project created to develop an online self-assessment tool that offers students the opportunity to plan their preparedness to enter the work place named the Preparation for Placement Assessment Tool. The aim of the project was to develop an artefact that aidsall students to think about and prepare for placements, and more broadly to be work-ready. It also aims to help disabled students to identify and manage their individual needs. Working in collaboration with students is offered as an effective strategy for improving project outcomes and managing the tensions for academics of balancing research, teaching, learning and scholarly activities.This paper discusses the project background, design and delivery, which includes the engagement of a diverse mix of students, and the practice research methodologies used. Discussion focuses on the projectâs impact, particularly on the students involved. Four key factors: student power, methodology, the use of funding and slow burn are identified as significant for success
Depletion of atmospheric nitrate and chloride as a consequence of the Toba Volcanic Eruption
Continuous measurements of SO42â and electrical conductivity (ECM) along the GISP2 ice core record the Toba megaâeruption at a depth 2590.95 to 2091.25 m (71,000±5000 years ago). Major chemical species were analyzed at a resolution of 1 cm per sample for this section. An âŒ6âyear long period with extremely high volcanic SO42â coincident with a 94% depletion of nitrate and 63% depletion of chloride is observed at the depth of the Toba horizon. Such a reduction of chloride in a volcanic layer preserved in an ice core has not been observed in any previous studies. The nearly complete depletion of nitrate (to 5 ppb) encountered at the Toba level is the lowest value in the entire âŒ250,000 years of the GISP2 ice core record. We propose possible mechanisms to explain the depletion of nitrate and chloride resulting from this megaâeruption
Volcanic aerosol records and tephrochronology of the Summit, Greenland, ice cores
The recently collected Greenland Ice Sheet Project 2 (GISP2) and Greenland Ice Core Project ice cores from Summit, Greenland, provide lengthy and highly resolved records of the deposition of both the aerosol (H2SO4) and silicate (tephra) components of past volcanism. Both types of data are very beneficial in developing the hemispheric to global chronology of explosive volcanism and evaluating the entire volcanismâclimate system. The continuous time series of volcanic SO42â for the last 110,000 years show a strong relationship between periods of increased volcanism and periods of climatic change. The greatest number of volcanic SO42â signals, many of very high magnitude, occur during and after the final stages of deglaciation (6000â17,000 years ago), possibly reflecting the increased crustal stresses that occur with changing volumes of continental ice sheets and with the subsequent changes in the volume of water in ocean basins (sea level change). The increase in the number of volcanic SO42â signals at 27,000â36,000 and 79,000â85,000 years ago may be related to initial ice sheet growth prior to the glacial maximum and prior to the beginning of the last period of glaciation, respectively. A comparison of the electrical conductivity of the GISP2 core with that of the volcanic SO42â record for the Holocene indicates that only about half of the larger volcanic signals are coincident in the two records. Other volcanic acids besides H2SO4 and other SO42â sources can complicate the comparisons, although the threshold level picked to make such comparisons is especially critical. Tephra has been found in both cores with a composition similar to that originating from the Vatnaöldur eruption that produced the Settlement Layer in Iceland (midâA.D. 870s), from the Icelandic eruption that produced the Saksunarvatn ash (âŒ10,300 years ago), and from the Icelandic eruption(s) that produced the Z2 ash zone in North Atlantic marine cores (âŒ52,700 years ago). The presence of these layers provides absolute time lines for correlation between the two cores and for correlation with proxy records from marine sediment cores and terrestrial deposits containing these same tephras. The presence of both rhyolitic and basaltic shards in the Z2 ash in theGISP2 core and the composition of the basaltic grains lend support to multiple Icelandic sources (Torfajökull area and Katla) for the Z2 layer. Deposition of the Z2 layer occurs at the beginning of a stadial event, further reflecting the possibility of a volcanic triggering by the effects of changing climatic conditions
A Coding Scheme for Other-initiated Repair Across Languages
We provide an annotated coding scheme for other-initiated repair, along with guidelines for building collections and aggregating cases based on interactionally relevant similarities and differences. The questions and categories of the scheme are grounded in inductive observations of conversational data and connected to a rich body of work on other-initiated repair in conversation analysis. The scheme is developed and tested in a 12-language comparative project and can serve as a stepping stone for future work on other-initiated repair and the systematic comparative study of conversational structures
