The complexities of failing (Social Work) students - a workshop for practice educators of Social Work students held at the University of Lincoln on Thursday 27th November 2014

This workshop for practice educators teaching social work students whilst on placement explored issues relating to failing students. Reasons why students might experience difficulties whilst on placement, early identification of problems, barriers to making a fail decision and resolution of concerns were discussed. The session considered how to evidence and articulate concerns in relation to HCPC Guidance on Conduct and Ethics for Students and the appropriate PCF levels and how to develop appropriate intervention plans, using the University's concerns process or Fitness to Practise procedures where necessary

Influence of hydrodynamics on the larval supply to hydrothermal vents on the East Pacific Rise

Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution June 2007Examination of the scales at which larval supply varies spatially and temporally, and correlation with concurrent physical observations can provide insights into larval transport mechanisms that contribute to structuring marine benthic communities. In order to facilitate field studies, this thesis first provides new morphological and genetic identifications for hydrothermal vent gastropod larvae along the northern East Pacific Rise. Daily and weekly variability in the supply of hydrothermal vent gastropod larvae to two hydrothermal vents, 1.6 km apart on the East Pacific Rise, were quantified concurrently with current velocity observations. The magnitude and temporal pattern of larval supply differed between vent sites, despite their close proximity. A strong correlation between along-axis flow and daily larval supply suggested that larval supply occurred primarily via along-axis transport between local sources 1-2 km apart. However, weekly larval supply appeared to be driven by larger spatial scales through losses associated with cross-axis flows and the passage of mesoscale eddies. Tracer movement within a quasi-geostrophic eddy model was consistent with the observations of decreased larval supply concurrent with an eddy observed via satellite altimetry. The tracer movement also indicated that deep eddy-induced flow could facilitate a long-distance dispersal event, enhancing dispersal between vents 100s km apart.Financial support was provided by a National Defense Science and Engineering Graduate Fellowship, the WHOI Academic Programs Office, a WHOI Ocean Venture Fund award, the Ocean Life Institute, the Deep Ocean Exploration Institute, and NSF grants OCE0424953 and NSF OCE9712233 to L.S.

First Nations Boil Water Advisories: New Methods and New Approaches for Risk Communication

When issuing drinking water advisories (such as boil water advisories, or BWAs) in First Nations, risk communicators must consider the unique historical, political, social and cultural context. A small number of studies have examined risk communication and message mapping in the First Nations context but First Nations drinking water-specific literature is scarce. A community-based participatory research (CBPR) project was conducted with two First Nations and their tribal council in Saskatchewan. The study examined the applicability of risk communication and message mapping in the First Nations context, with the overall goals of improving local risk communication practices and contributing to a First Nations drinking water risk communication framework. Using the Science in a Circle © model, the research partners developed a four-phase CBPR project, rooted in mutual respect for Indigenous and western science worldviews. Through a series of initial community meetings, the research team determined a novel method would be required to investigate boil water advisory communications using culturally appropriate methods. The Participatory Dot-Mapping Method enabled local leaders, experts and everyday community members to participate in all steps of the research process, including data interpretation. Using coloured dots on a map-like response board, participants from each community used coloured dots to note their main concerns, questions and information needs around BWAs. Current and potential BWA communication tactics were also evaluated. Age-coded dot colours showed differences between life stages or age groups. The results suggest effective risk communication must consider factors unique to each community. These include frequency of advisories and preferred methods of communication (e.g. radio, social media, interpersonal communication). Door-to-door flyers and social media alerts were more popular in one community, with youth and/or Elders showing more interest in other electronic alerts (e.g. text, email). Door-to-door flyers and local radio alerts were more popular in the other community. Like non-Indigenous communities, more research is needed to understand how frequency of boil water advisories should inform their communication, and/or what kinds of messages can improve communications of BWAs. Communities should consider health promotion and education activities around BWAs between advisories. Overall, the Science in a Circle © approach and the Participatory Dot-Mapping Method generated actionable local policy knowledge for First Nations and their agencies

Rebuilding a Vent Community: Lessons from the EPR Integrated Study Site

The discovery of a seafloor eruption at the East Pacific Rise (EPR ) in 1991 presented an opportunity to examine the colonization and assembly of macrofaunal communities at newly formed diffuse-flow vents as well as to document the changes in community composition (Shank et al., 1998) in the context of temperature variation (Scheirer et al., 2006) and fluid chemistry (Von Damm and Lilley, 2004). The eruption site became a focus of the Ridge 2000 EPR Integrated Study Site (ISS) established to facilitate studies of the interaction of biological, geochemical, and/or physical processes associated with seafloor spreading. A second seafloor eruption in 2005–2006 provided opportunities to not only observe changes in community composition and environmental conditions, but also to deploy colonization substrata and other specialized equipment from “time zero.” Here we focus on how larval dispersal and recruitment contribute to the establishment of hydrothermal vent communities

Larval Dispersal: Vent Life in the Water Column

Visually striking faunal communities of high abundance and biomass cluster around hydrothermal vents, but these animals don’t spend all of their lives on the seafloor. Instead, they spend a portion of their lives as tiny larvae in the overlying water column. Dispersal of larvae among vent sites is critical for population maintenance, colonization of new vents, and recolonization of disturbed vents. Historically, studying larvae has been challenging, especially in the deep sea. Advances in the last decade in larval culturing technologies and more integrated, interdisciplinary time-series observations are providing new insights into how hydrothermal vent animals use the water column to maintain their populations across ephemeral and disjunct habitats. Larval physiology and development are often constrained by evolutionary history, resulting in larvae using a diverse set of dispersal strategies to interact with the surrounding currents at different depths. These complex biological and oceanographic interactions translate the reproductive output of adults in vent communities into a dynamic supply of settling larvae from sources near and far

15-An Archaeological Survey in Pavilion and Schoolcraft Townships, Kalamazoo County, Michigan

During the 1984 field season, Dr. William Cremin and the Western Michigan University archaeological field school continued the program of site location survey that had been initiated two years earlier in Pavilion Township (T3S RlOW), Kalamazoo County, Michigan. In addition, a small area flanking the north end of Barton Lake in nearby Schoolcraft Township (T4S RllW) was similarly evaluated. With the cooperation of numerous area landowners and local artifact collectors, almost 40 parcels of land aggregating 361 ha in Pavilion and 33 ha in Schoolcraft townships were surveyed by means of surface reconnaissance procedures. There follows a report of our survey activity, including descriptions of the archaeological sites that were recorded and collected and recommendations regarding the proper disposition of several \u27\u27problem\u27\u27 sites; the latter reflect in one instance disagreement among the documentary sources as to the location of a burial mound and in a second the erroneous recording of a natural feature on the landscape as a cultural phenomenon (i.e. burial mound)

Persistent effects of disturbance on larval patterns in the plankton after an eruption on the East Pacific Rise

The definitive version was published in Marine Ecology Progress Series 491 (2013): 67-76, doi:10.3354/meps10463.To predict how benthic communities will respond to disturbance, it is necessary to understand how disturbance affects the planktonic larval supply available to recolonize the area. Deep-sea hydrothermal vent fauna along the East Pacific Rise (EPR) experience frequent local extinctions due to tectonic and magmatic events, but the effects on regional larval abundance and diversity are unknown. We had been monitoring larvae at 9° 50' N on the EPR prior to the 2006 eruption and were able to resume collections shortly afterward. We found that many species that were common before the eruption became significantly less so afterward, whereas a few other species experienced a transient spike in abundance. Surprisingly, overall species richness in the plankton was high 9 mo after the eruption, but then decreased sharply after 1 yr and had not returned to pre-eruption levels after 2 yr. These results suggest that recovery from disturbance may continue to be affected by limited larval supply even several years after a disturbance event. This delay in recovery means that larvae of pioneer species may dominate potential colonists, even after benthic habitats have transitioned to conditions that favor later-successional species. Moreover, the combined effects of natural and anthropogenic disturbance (e.g. mining) would be likely to cause more profound and long-lasting changes than either event alone. Our results indicate that we do not have sufficient data to predict the timing of recovery after disturbance in the deep sea, even in a well-studied vent system.Support was provided by National Science Foundation Grant OCE-0424953 and a Woods Hole Oceanographic Institution grant from the Deep Ocean Exploration Institute
