Investigation of the origin of shallow gas in Outer Moray Firth open blocks 15/20c 15/25d (seabed-400 milliseconds two way time)
1. Interpretations of the BGS shallow seismic data and commercial site investigation data show that gas is seeping from seabed in three large active pockmark complexes in approximately 150m or more water depth. The Challenger pockmark complex is in the north of block 15 / 25d, the Scanner pockmark complex is in the south of block 15 / 25d and the Scotia pockmark complex is adjacent and northeast of the Scanner pockmark.
2. A review of the peer-reviewed scientific publications indicates that the majority of the arguments, based on isotopic analyses, are for a predominantly biological origin for the gas seeping from the active pockmarks. There is not, however, a secure scientific consensus as to whether there is a primary origin for the gas. Thus the possibilities are that the gas originates from a shallow biogenic source, a deep thermogenic source or from mixtures of these sources.
3. Interpretations undertaken for this project indicate that gas seeping to seabed in the largest pockmarks is sited above the shoulders of buried sub-glacial channels. The gas seepages are fed from a laterally almost continuous blanket of buried gas-charged sediments situated between the sub-glacial channel margins at a depth interval of approximately 280-300ms two-way time (down to approximately120m below seabed).
4. An empirical conclusion is that loss of shallow gas from the gas-charged interval at approximately 280-300ms two-way time will cut off the supply of shallow gas to the active pockmarks.
5. The regional unconformity at the Crenulate Rreflector is the focus for shallow gas accumulation and it is a significant conduit for shallow gas ascending from depth to the east of the study area and into the study area
Composition in Theme and Variations Form
We decided to study theme and variations composition because we found that it is very relevant and applicable to what we are learning in our Music Theory class. Variations form is also accessible to listeners and beginning composers. We hope that after our presentation, those listening will feel more comfortable in listening to and creating their own piece Theme and Variations form is a standard form of musical composition where a simple, unembellished melody is used as a theme and then repeated several times with melodic, rhythmic, harmonic, or other variations. We will take a theme and variations piece, Mozart\u27s Ah! vous dirai je maman Twinkle Twinkle, Little Star KV 265, and analyze what the theme is, and how the composer used variations of that theme in the piece. We will demonstrate the variation form with an audio timeliner diagram and audio clip. After demonstrating the form, we will show how to compose a piece in variation form, using our own original composition
Preparing Family Caregivers to Recognize Delirium Symptoms in Older Adults After Elective Hip or Knee Arthroplasty
Objectives
To test the feasibility of a telephone-based intervention that prepares family caregivers to recognize delirium symptoms and how to communicate their observations to healthcare providers. Design
Mixed-method, pre–post quasi-experimental design. Setting
A Midwest Veterans Affairs Medical Center and a nonprofit health system. Participants
Forty-one family caregiver-older adult dyads provided consent; 34 completed the intervention. Intervention
Four telephone-based education modules using vignettes were completed during the 3 weeks before the older adult\u27s hospital admission for elective hip or knee replacement. Each module required 20 to 30 minutes. Measurements
Interviews were conducted before the intervention and 2 weeks and 2 months after the older adult\u27s hospitalization. A researcher completed the Confusion Assessment Method (CAM) and a family caregiver completed the Family Version of the Confusion Assessment Method (FAM-CAM) 2 days after surgery to assess the older adults for delirium symptoms. Results
Family caregivers’ knowledge of delirium symptoms improved significantly from before the intervention to 2 weeks after the intervention and was maintained after the older adult\u27s hospitalization. They also were able to recognize the presence and absence of delirium symptoms in the vignettes included in the intervention and in the older adult after surgery. In 94% of the cases, the family caregiver rating on the FAM-CAM approximately 2 days after the older adult\u27s surgery agreed with the researcher rating on the CAM. Family caregivers expressed satisfaction with the intervention and stated that the information was helpful. Conclusion
Delivery of a telephone-based intervention appears feasible. All family caregivers who began the program completed the four education modules. Future studies evaluating the effectiveness of the educational program should include a control group
Languages learning at Key Stage 2: a longitudinal study
This is the final report of a 3 year longitudinal study of the teaching of French, German and Spanish at Key Stage 2, funded from 2006-2009 by the Department for Children Schools and Families. The report covers the attitudes of teachers and children towards languages; the organisation and administration of languages within primary schools; current practice in the teaching of languages; the development of children's intercultural understanding; children's attainment in target language oracy and literacy; and concludes with a discussion of the future sustainability of languages in the primary curriculum and steps needed to secure this
Perceived Readiness for Hospital Discharge in Adult Medical-Surgical Patients
Purpose: The purpose of the study was to identify predictors and outcomes of adult medical-surgical patients\u27 perceptions of their readiness for hospital discharge. Design: A correlational, prospective, longitudinal design with path analyses was used to explore relationships among transition theory-related variables. Setting: Midwestern tertiary medical center. Sample: 147 adult medical-surgical patients. Methods: Predictor variables included patient characteristics, hospitalization factors, and nursing practices that were measured prior to hospital discharge using a study enrollment form, the Quality of Discharge Teaching Scale, and the Care Coordination Scale. Discharge readiness was measured using the Readiness for Hospital Discharge Scale administered within 4 hours prior to discharge. Outcomes were measured 3 weeks postdischarge with the Post-Discharge Coping Difficulty Scale and self-reported utilization of health services. Findings: Living alone, discharge teaching (amount of content received and nurses\u27 skill in teaching delivery), and care coordination explained 51% of readiness for discharge score variance. Patient age and discharge readiness explained 16% of variance in postdischarge coping difficulty. Greater readiness for discharge was predictive of fewer readmissions. Conclusions: Quality of the delivery of discharge teaching was the strongest predictor of discharge readiness. Study results provided support for Meleis\u27 transitions theory as a useful model for conceptualizing and investigating the discharge transition. Implications for Practice: The study results have implications for the CNS role in patient and staff education, system building for the postdischarge transition, and measurement of clinical care outcomes

Tracing an ethic of care in the policy and practice of the Troubled Families Programme
Drawing upon the Trace method developed by Selma Sevenhuijsen (2004), this paper has traced the discourse constructed in two key Troubled Families Programme (TFP) policy documents through the lens of care ethics, highlighting tensions between ‘care’ and ‘justice’ orientations in the neoliberal family intervention model. It is argued that whilst the family intervention model advocated has the potential to provide families with support underpinned by an ethic of care, the TFP's managerialist tendencies also create challenges to the integration of care ethics within such services. Given that the programme's financial framework generates considerable opportunity for local variation in policy implementation, the ethics of care offer a valuable moral framework by which to evaluate local practice. Moreover, engaging with a distinctly feminist ethic of care renders visible to family support services the inequalities produced through the gendered distribution of ‘caring’ responsibilities, and highlights the need for interventions to address rather than reinforce these inequalities
Parkinson\u27s disease and the gastrointestinal microbiome
Recently, there has been a surge in awareness of the gastrointestinal microbiome (GM) and its role in health and disease. Of particular note is an association between the GM and Parkinson’s disease (PD) and the realisation that the GM can act via a complex bidirectional communication between the gut and the brain. Compelling evidence suggests that a shift in GM composition may play an important role in the pathogenesis of PD by facilitating the characteristic ascending neurodegenerative spread of α-synuclein aggregates from the enteric nervous system to the brain. Here, we review evidence linking GM changes with PD, highlighting mechanisms supportive of pathological α-synuclein spread and intestinal inflammation in PD. We summarise existing patterns and correlations seen in clinical studies of the GM in PD, together with the impacts of non-motor symptoms, medications, lifestyle, diet and ageing on the GM. Roles of GM modulating therapies including probiotics and faecal microbiota transplantation are discussed. Encouragingly, alterations in the GM have repeatedly been observed in PD, supporting a biological link and highlighting it as a potential therapeutic target
