An exploratory study of the effects of mindfulness on perceived levels of stress among school-children from lower socioeconomic backgrounds
Children from lower socioeconomic backgrounds are at increased risk of experiencing
stress and associated social-emotional difficulties and behavioural problems, which can
undermine academic performance and lead to school drop-out. Previous studies
investigating the effects of mindfulness have evidenced positive outcomes among
children pertaining to enhanced well-being, school-based competence and decreased
levels of stress and anxiety. However, these studies have typically examined teacher’s
perceptions of change or quantitative outcomes without consideration of children’s
experiences. The present study employs an interpretative qualitative approach to gain a
greater understanding of children’s experiences of mindfulness in dealing with stress. A
5-week school-based mindfulness program was performed with 63 primary school
children at risk of social exclusion in education. Interviews were undertaken with 16
children and 2 teachers. Thematic analysis identified five key themes labelled
conceptualisation of stress, awareness, self-regulation, classroom regulations and
addressing future stress. Quantitative measures of children’s perceived stress levels
evaluated at baseline and follow-up also revealed significant reductions post
intervention. These findings offer support for the incorporation of mindfulness
interventions into the school curriculum, as a means of empowering children to address
stress in their lives and improving full participation in the education system.peer-reviewe
Resolving Conflict through Explicit Bargaining
This article analyzes the impact of conciliatory initiatives on conflict resolution in two-party bargaining. It specifically develops and tests a theory of unilateral initiatives derived from Osgood\u27s (1962) notion of Graduated and Reciprocated Initiatives in Tension Reduction (GRIT). The major propositions of the theory indicate that, given a pattern of mutual resistance or hostility, unilateral initiatives and tit-for-tat retaliation in response to punitive action will produce more conciliation and less hostility by an opponent. To test the theory, a bargaining setting was created in a laboratory experiment in which parties exchanged offers and counteroffers on an issue across a number of rounds while also having the option to engage in punitive action against one another. The results indicated that (1) unilateral initiatives produced more concession making and less hostility than a reciprocity strategy, and (2) tit-for-tat retaliation heightened hostility initially but reduced it over time. The article suggests some general, abstract conditions under which two parties in conflict can produce conciliation and reach agreements without the intervention of third parties

Improving shop floor visualization and metrics
Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management; and, (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering; in conjunction with the Leaders for Global Operations Program at MIT, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 55-57).Within the Technical Operations division of Novartis Pharmaceuticals, there is an aggressive vision to be the "Toyota" of the Pharma Industry by 2010. To accomplish this, PharmOps Switzerland has embraced operational excellence, IQP (Innovation, Quality, and Productivity). Still, there is more that the site, and more specifically manufacturing, can do to fully realize the benefits of adopting all aspects of IQP. Currently, there is a lack of adequate visualization on the shop floor. The current status and schedule of production cannot be quickly seen at the tools where the work is being performed. This thesis focuses is on improving the visualization and creating a set of KPIs (Key Performance Indicators) and visual displays that will improve performance Change, especially cultural, is difficult and takes considerable time and effort. Even when changes are implemented slowly with small iterations, it might not be well received. Without a strong culture of continuous improvement, teams may not perceive that there are things that can be improved. Historical metrics are comfortable and useful to the shop floor. Visual metrics have improved communication.by Maureen E. Lawler.S.M.M.B.A
New Rare Earth Element Abundance Distributions for the Sun and Five r-Process-Rich Very Metal-Poor Stars
We have derived new abundances of the rare-earth elements Pr, Dy, Tm, Yb, and
Lu for the solar photosphere and for five very metal-poor, neutron-capture
r-process-rich giant stars. The photospheric values for all five elements are
in good agreement with meteoritic abundances. For the low metallicity sample,
these abundances have been combined with new Ce abundances from a companion
paper, and reconsideration of a few other elements in individual stars, to
produce internally-consistent Ba, rare-earth, and Hf (56<= Z <= 72) element
distributions. These have been used in a critical comparison between stellar
and solar r-process abundance mixes.Comment: 48 pages, 11 figures, 12 tables: To appear in the Astrophysical

MRSA Nasal Carriage Patterns and the Subsequent Risk of Conversion between Patterns, Infection, and Death
Background: Patterns of methicillin-resistant S. aureus (MRSA) nasal carriage over time and across the continuum of care settings are poorly characterized. Knowledge of prevalence rates and outcomes associated with MRSA nasal carriage patterns could help direct infection prevention strategies. The VA integrated health-care system and active surveillance program provides an opportunity to delineate nasal carriage patterns and associated outcomes of death, infection, and conversion in carriage. Methods/Findings: We conducted a retrospective cohort study including all patients admitted to 5 acute care VA hospitals between 2008–2010 who had nasal MRSA PCR testing within 48 hours of admission and repeat testing within 30 days. The PCR results were used to define a baseline nasal carriage pattern of never, intermittently, or always colonized at 30 days from admission. Follow-up was up to two years and included acute, long-term, and outpatient care visits. Among 18,038 patients, 91.1%, 4.4%, and 4.6% were never, intermittently, or always colonized at the 30-day baseline. Compared to non-colonized patients, those who were persistently colonized had an increased risk of death (HR 2.58; 95% CI 2.18;3.05) and MRSA infection (HR 10.89; 95% CI 8.6;13.7). Being in the non-colonized group at 30 days had a predictive value of 87% for being non-colonized at 1 year. Conversion to MRSA colonized at 6 months occurred in 11.8% of initially non-colonized patients. Age >70 years, long-term care, antibiotic exposure, and diabetes identified >95% of converters. Conclusions: The vast majority of patients are not nasally colonized with MRSA at 30 days from acute hospital admission. Conversion from non-carriage is infrequent and can be risk-stratified. A positive carriage pattern is strongly associated with infection and death. Active surveillance programs in the year following carriage pattern designation could be tailored to focus on non-colonized patients who are at high risk for conversion, reducing universal screening burden

Relationships of Sun-Protection Habit Strength with Sunscreen Use During Outdoor Sport and Physical Activity
The objective of this cross-sectional questionnaire study was to assess associations of a self-report index of sun protection habit strength with sunscreen use in sporting environments and outdoor physical activity. Participants (n = 234) in field hockey, soccer, tennis and surf sports in Queensland, Australia, completed a self-administered survey on sun protection during organized sport, and during general outdoor physical activity during 2005/2006. The sun protection habit strength index was dichotomized into two categories. Multinomial logistic regression analyses assessed the associations of low versus high sun protection habit strength with three categories of sunscreen use (no or rare use; inadequate use; and adequate use). Compared to participants with low sun protection habit strength, those with high sun protection habit strength had significantly greater odds of any sunscreen use during organized sport and during general outdoor physical activity. This association was strongest for adequate sunscreen use in both settings. In conclusion, this study suggests that the measure of sun protection habit strength is a potentially useful assessment tool for future sun protection studies
Need for Aeromedical Evacuation High-Level Containment Transport Guidelines
Circumstances exist that call for the aeromedical evacuation high-level containment transport (AE-HLCT) of patients with highly hazardous communicable diseases. A small number of organizations maintain AE-HLCT capabilities, and little is publicly available regarding the practices. The time is ripe for the development of standards and consensus guidelines involving AE-HLCT
Correlates of pedometer use: Results from a community-based physical activity intervention trial (10,000 Steps Rockhampton)
Background: Pedometers have become common place in physical activity promotion, yet little information exists on who is using them. The multi-strategy, community-based 10,000 Steps Rockhampton physical activity intervention trial provided an opportunity to examine correlates of pedometer use at the population level. Methods: Pedometer use was promoted across all intervention strategies including: local media, pedometer loan schemes through general practice, other health professionals and libraries, direct mail posted to dog owners, walking trail signage, and workplace competitions. Data on pedometer use were collected during the 2-year follow-up telephone interviews from random population samples in Rockhampton, Australia, and a matched comparison community (Mackay). Logistic regression analyses were used to determine the independent influence of interpersonal characteristics and program exposure variables on pedometer use. Results: Data from 2478 participants indicated that 18.1% of Rockhampton and 5.6% of Mackay participants used a pedometer in the previous 18-months. Rockhampton pedometer users (n = 222) were more likely to be female (OR = 1.59, 95% CI: 1.11, 2.23), aged 45 or older (OR = 1.69, 95% CI: 1.16, 2.46) and to have higher levels of education (university degree OR = 4.23, 95% CI: 1.86, 9.6). Respondents with a BMI > 30 were more likely to report using a pedometer (OR = 1.68, 95% CI: 1.11, 2.54) than those in the healthy weight range. Compared with those in full-time paid work, respondents in 'home duties' were significantly less likely to report pedometer use (OR = 0.18, 95% CI: 0.06, 0.53). Exposure to individual program components, in particular seeing 10,000 Steps street signage and walking trails or visiting the website, was also significantly associated with greater pedometer use. Conclusion: Pedometer use varies between population subgroups, and alternate strategies need to be investigated to engage men, people with lower levels of education and those in full-time 'home duties', when using pedometers in community-based physical activity promotion initiatives
