Differences in the way local and regional interest groups perceive Sustainable Forest Management in regions with different forest use histories were studied using Southeastern Finland, the Mauricie in Quebec and Central Labrador in Canada as examples of regions with high, medium and low importance of commercial forestry. We present a conceptual model illustrating the cyclic interaction between the forest, cultural models about forests and forest management. We hypothesized that peoples' perceptions would be influenced by their cultural models about forests and would thus vary amongst regions with different forest use histories and among different interest groups. The weightings of the environmental, economic and social components of sustainability as well as themes important for each of the interest groups were elicited using individual listing of SFM indicators and group work aimed at developing a consensus opinion on a common indicator list. In Southeastern Finland the views of the different groups were polarized along the environment-economy axis, whereas in Central Labrador all groups were environmentally oriented. The social dimension was low overall except among the Metis and the Innu in Labrador. Only environmental groups were similar in all three research regions, the largest differences between regions were found among the forestry professionals in their weightings concerning economy and nature. As the importance of commercial forestry increased, a greater importance of economic issues was expressed whereas the opposite trend was observed for issues regarding nature. Also inter-group differences grew as the importance of commercial forestry increased in the region. Forest management and forest use can be seen as factors strongly influencing peoples' cultural models on forests.

Greater sage-grouse population trends across Wyoming

USGS Publications Warehouse

Edmunds, David; Aldridge, Cameron L.; O'Donnell, Michael; Monroe, Adrian

2018-01-01

The scale at which analyses are performed can have an effect on model results and often one scale does not accurately describe the ecological phenomena of interest (e.g., population trends) for wide-ranging species: yet, most ecological studies are performed at a single, arbitrary scale. To best determine local and regional trends for greater sage-grouse (Centrocercus urophasianus) in Wyoming, USA, we modeled density-independent and -dependent population growth across multiple spatial scales relevant to management and conservation (Core Areas [habitat encompassing approximately 83% of the sage-grouse population on ∼24% of surface area in Wyoming], local Working Groups [7 regional areas for which groups of local experts are tasked with implementing Wyoming's statewide sage-grouse conservation plan at the local level], Core Area status (Core Area vs. Non-Core Area) by Working Groups, and Core Areas by Working Groups). Our goal was to determine the influence of fine-scale population trends (Core Areas) on larger-scale populations (Working Group Areas). We modeled the natural log of change in population size ( peak M lek counts) by time to calculate the finite rate of population growth (λ) for each population of interest from 1993 to 2015. We found that in general when Core Area status (Core Area vs. Non-Core Area) was investigated by Working Group Area, the 2 populations trended similarly and agreed with the overall trend of the Working Group Area. However, at the finer scale where Core Areas were analyzed separately, Core Areas within the same Working Group Area often trended differently and a few large Core Areas could influence the overall Working Group Area trend and mask trends occurring in smaller Core Areas. Relatively close fine-scale populations of sage-grouse can trend differently, indicating that large-scale trends may not accurately depict what is occurring across the landscape (e.g., local effects of gas and oil fields may be masked by increasing larger populations).

VIP1 is very important/interesting protein 1 regulating touch responses of Arabidopsis.

PubMed

Tsugama, Daisuke; Liu, Shenkui; Takano, Tetsuo

2016-06-02

VIP1 (VIRE2-INTERACTING PROTEIN 1) is a bZIP transcription factor in Arabidopsis thaliana. VIP1 and its close homologs (i.e., Arabidopsis group I bZIP proteins) are present in the cytoplasm under steady conditions, but are transiently localized to the nucleus when cells are exposed to hypo-osmotic conditions, which mimic mechanical stimuli such as touch. Recently we have reported that overexpression of a repression domain-fused form of VIP1 represses the expression of some touch-responsive genes, changes structures and/or local auxin responses of the root cap cells, and enhances the touch-induced root waving. This raises the possibility that VIP1 suppresses touch-induced responses. VIP1 should be useful to further characterize touch responses of plants. Here we discuss 2 seemingly interesting perspectives about VIP1: (1) What factors are involved in regulating the nuclear localization of VIP1?; (2) What can be done to further characterize the physiological functions of VIP1 and other Arabidopsis group I bZIP proteins?

Stakeholder opinions on the assessment of MPA effectiveness and their interests to participate at Pacific Rim National Park Reserve, Canada.

PubMed

Heck, Nadine; Dearden, Philip; McDonald, Adrian; Carver, Steve

2011-04-01

As the number of marine protected areas (MPAs) is globally increasing, information is needed on the effectiveness of existing sites. Many protected area agencies however have limited resources and are unable to evaluate MPA effectiveness. An evaluation conducted entirely by the managing agency may also lack credibility. Long-term monitoring and evaluation programs should ideally offer opportunities for participation of diverse groups in the selection of evaluation indicators and their assessment. A participatory approach has the potential to enhance evaluation capacity, to increase credibility and acceptance of results, to strengthen relationships between managers and local stakeholders, and to address more locally relevant information. Using a case study approach, this paper investigates diverse stakeholder groups' opinions on the design of an evaluation and their interest to participate in an assessment. Respondents were most interested in the assessment of MPA achievements and outcome indicators. Most groups identified a range of government agencies and stakeholders that should participate in an assessment but only half of all respondents were interested to participate in monitoring activities. Most frequently mentioned limitations for more participation were a lack of time and money, but also governance shortcomings such as limited participation possibilities and not paying enough credit to stakeholders' input. Participation interest was also influenced by occupation, place of residency, and familiarity with the marine environment. Differences exist among stakeholders about suitable evaluators and preferred monitoring partners, which could affect the credibility of evaluation results and affect monitoring activities.

The development of education indicators for measuring quality in the English-speaking Caribbean: how far have we come?

PubMed

Bowe, Anica G

2015-02-01

Education evaluation has become increasingly important in the English-speaking Caribbean. This has been in response to assessing the progress of four regional initiatives aimed at improving the equity, efficiency, and quality of education. Both special interest groups and local evaluators have been responsible for assessing the progress of education and providing an overall synthesis and summary of what is taking place in the English-speaking Caribbean. This study employed content analysis to examine the indicators used in these education evaluation studies since the declaration of the Caribbean Plan of Action 2000-2015 to determine these indicators' appropriateness to the Caribbean context in measuring education progress. Findings demonstrate that the English-speaking Caribbean has made strides in operationalizing quality input, process, and output indicators; however quality outcome indicators beyond test scores are yet to be realized in a systematic manner. This study also compared the types of collaborative partnerships in conducting evaluation studies used by special interest groups and local evaluators and pinpointed the one that appears most suitable for special interest groups in this region.

Book clubs and discussion groups provide opportunities for hospital librarians to reach out to staff from all areas of their facilities while introducing them to literature reflecting participants' personal and professional interests. Librarians presenting these case studies have coordinated local book clubs where topics ranged from titles about the nature of healing, to leadership development, and patient-centered care. Some also included contemporary novels of interest to participants. No matter the setting or scope of material discussed, each group has provided unique networking opportunities for staff to meet others working in various departments of their facilities.

Automatic localization of the left ventricular blood pool centroid in short axis cardiac cine MR images.

PubMed

Tan, Li Kuo; Liew, Yih Miin; Lim, Einly; Abdul Aziz, Yang Faridah; Chee, Kok Han; McLaughlin, Robert A

2018-06-01

In this paper, we develop and validate an open source, fully automatic algorithm to localize the left ventricular (LV) blood pool centroid in short axis cardiac cine MR images, enabling follow-on automated LV segmentation algorithms. The algorithm comprises four steps: (i) quantify motion to determine an initial region of interest surrounding the heart, (ii) identify potential 2D objects of interest using an intensity-based segmentation, (iii) assess contraction/expansion, circularity, and proximity to lung tissue to score all objects of interest in terms of their likelihood of constituting part of the LV, and (iv) aggregate the objects into connected groups and construct the final LV blood pool volume and centroid. This algorithm was tested against 1140 datasets from the Kaggle Second Annual Data Science Bowl, as well as 45 datasets from the STACOM 2009 Cardiac MR Left Ventricle Segmentation Challenge. Correct LV localization was confirmed in 97.3% of the datasets. The mean absolute error between the gold standard and localization centroids was 2.8 to 4.7 mm, or 12 to 22% of the average endocardial radius.

Separating Judicial from Legislative Reasoning in Moral Dilemma Interviews.

PubMed

Langford, Peter E

1997-12-01

Unlike previous studies of the development of reasoning about moral dilemmas, the 2 studies reported separated judicial reasoning (the application of rules) from legislative reasoning (the justification of rules), as well as attending to other aspects of context, using a modification of the weakly interpretive scoring method of Langford and D'Cruz. This assigns justifications to relatively simple conceptually defined categories. Findings were in accord with substantially modified versions of the views of Piaget and Kohlberg, according to which legislative reasoning can be divided into 3 main types of stages in the period 7-21 years: heteronomy (Piaget) or egocentrism (Kohlberg); local groups (attention to group interests, harmony, and reciprocity in local groups), wider groups (attention to these thing in wider groups). Findings contradicted Gibbs's theory.

Stop, Collaborate, and Listen: Lessons Learned from Collaborating with a Houston Environmental Justice Organization

Johnson, C.; Arellano, Y.; Phartiyal, P.

2016-12-01

Scientists are increasingly showing interest in conducting research at the community level, yet community groups often struggle with lack of access to scientific information. Collaborations between the two are mutually beneficial: scientists can include assessment of societal implications in their research, and community-specific scientific evidence can be used by local groups to inform public decisions that benefit community interests. Recognizing the need for and utility of such partnerships, the Center for Science and Democracy at the Union of Concerned Scientists, a science-based policy and advocacy organization, partnered with Texas Environmental Justice Advocacy Services (TEJAS), an environmental justice organization based in Manchester in Houston, to provide the technical support and resources needed to strengthen TEJAS' advocacy work. Working closely with TEJAS, we connected community members with local experts, developed educational products to inform community members about environmental health risks in their neighborhoods, published a report highlighting chemical safety issues in the community, and assisted in constructing a community survey to assess residents' health concerns. The products were created with the intention of raising the profile of these issues with local government and regional EPA officials. This talk will discuss the projects done in collaboration with TEJAS, as well as important lessons learned that offer insight into best practices for other organizations and technical experts to partner with community groups on local projects.

An Institutional Community-Driven effort to Curate and Preserve Geospatial Data using GeoBlacklight

NASA Astrophysics Data System (ADS)

Petters, J.; Coleman, S.; Andrea, O.

2016-12-01

A variety of geospatial data is produced or collected by both academic researchers and non-academic groups in the Virginia Tech community. In an effort to preserve, curate and make this geospatial data discoverable, the University Libraries have been building a local implementation of GeoBlacklight, a multi-institutional open-source collaborative project to improve the discoverability and sharing of geospatial data. We will discuss the local implementation of Geoblacklight at Virginia Tech, focusing on the efforts necessary to make it a sustainable resource for the institution and local community going forward. This includes technical challenges such as the development of uniform workflows for geospatial data produced within and outside the course of research, but organizational and economic barriers must be overcome as well. In spearheading this GeoBlacklight effort the Libraries have partnered with University Facilities and University IT. The IT group manages the storage and backup of geospatial data, allowing our group to focus on geospatial data collection and curation. Both IT and University Facilities are in possession of localized geospatial data of interest to Viriginia Tech researchers that all parties agreed should be made discoverable and accessible. The interest and involvement of these and other university stakeholders is key to establishing the sustainability of the infrastructure and the capabilities it can provide to the Virginia Tech community and beyond.

The Implementation of the Food Safety Modernization Act and the Strength of the Sustainable Agriculture Movement.

PubMed

Wiseman, Samuel R

2015-01-01

In the wake of growing public concerns over salmonella outbreaks and other highly publicized food safety issues, Congress passed the FDA Food Safety Modernization Act in 2011, which placed more stringent standards on food growing and packaging operations. In negotiations preceding the Act's passage, farmers of local, sustainable food argued that these rules would unduly burden local agricultural operations or, at the extreme, drive them out of business by creating overly burdensome rules. These objections culminated in the addition of the Tester-Hagan Amendment to the Food Safety Modernization Act, which created certain exemptions for small farms. Proposed Food and Drug Administration (FDA) rules to implement the Act threatened to weaken this victory for small farm groups, however, prompting a loud response from small farmers and local food proponents. The FDA's second set of proposed rules, issued in September 2014 in response to these and other complaints, were, perhaps surprisingly, responsive to small farmers' concerns. Using comments submitted to the FDA, this article explores the responses of the agriculture industry and public health organizations, as well as small farm groups, consumers of local food, and sustainable agriculture interests (which, for simplicity, I alternately describe as comprising the "sustainable agriculture" or "small farm" movement), to three aspects of the FDA's proposed rules--involving manure application, on-farm packing activities, and exemptions for very small farms--to assess the strength of the sustainable agriculture movement. The rules involving manure application and on-farm packing, it turns out, reveal little about the independent political strength of the local food movement, as large industry groups also objected to these provisions. But for the third issue discussed here--exemptions for very small farms--the interests of sustainable agriculture groups were directly opposed to both industry and public health organizations, and yet prevailed. This suggests that the high salience of locavore and "slow food" issues might have allowed relatively small, dispersed interests to overcome traditional obstacles to political organization, and that the sustainable agriculture movement has indeed become an effective political force.

The Hubble diagram for a system within dark energy: influence of some relevant quantities

NASA Astrophysics Data System (ADS)

Saarinen, J.; Teerikorpi, P.

2014-08-01

Aims: We study the influence of relevant quantities, including the density of dark energy (DE), to the predicted Hubble outflow around a system of galaxies. In particular, we are interested in the difference between two models: 1) the standard ΛCDM model, with the everywhere constant DE density, and 2) the "Swiss cheese model", where the Universe is as old as the standard model and the DE density is zero on short scales, including the environment of the system. Methods: We calculated the current predicted outflow patterns of dwarf galaxies around the Local Group-like system, using different values for the mass of the group, the local DE density, and the time of ejection of the dwarf galaxies, which are treated as test particles. These results are compared with the observed Hubble flow around the Local Group. Results: The predicted distance-velocity relations around galaxy groups are not very sensitive indicators of the DE density, owing to the observational scatter and the uncertainties caused by the mass used for the group and a range in the ejection times. In general, the Local Group outflow data agree with the local DE density being equal to the global one, if the Local Group mass is about 4 × 1012 M⊙; a lower mass ≲ 2 × 1012 M⊙ could suggest a zero local DE density. The dependence of the inferred DE density on the mass is a handicap in this and other common dynamical methods. This emphasizes the need to use different approaches together, for constraining the local DE density.

Schools are uniquely positioned to influence the dietary habits of children, and farm-to-school programs can increase fruit and vegetable consumption among school-aged children. We assessed the feasibility of, interest in, and barriers to implementing farm-to-school activities in 7 school districts in Douglas County, Nebraska. We used a preassessment and postassessment survey to obtain data from 3 stakeholder groups: school food service directors, local food producers, and food distributors. We had a full-time farm-to-school coordinator who was able to engage multiple stakeholders and oversee the development and dissemination of a toolkit. We used descriptive statistics to make comparisons. Seven food service directors, 5 distributors identified by the food service directors, and 57 local producers (9 completed only the preassessment survey, 16 completed only the postassessment survey, and 32 completed both) completed various components of the assessment. Interest in pursuing farm-to-school activities to incorporate more local foods in the school lunch program increased during the 2-year project; mean interest in purchasing local foods by food service directors for their districts increased from 4.4 to 4.7 (on a scale of 1 to 5). Implementing farm-to-school programming in Douglas County, Nebraska, is feasible, although food safety and distribution is a main concern among food service directors. Additional research on feasibility, infrastructure, and education is recommended.

The necessary contradictions of 'community-led' health promotion: a case study of HIV prevention in an Indian red light district.

PubMed

Cornish, Flora; Ghosh, Riddhi

2007-01-01

Health promotion interventions with marginalised groups are increasingly expected to demonstrate genuine community participation in their design and delivery. However, ideals of egalitarian democratic participation are far removed from the starting point of the hierarchical and exploitative social relations that typically characterise marginalised communities. What scope is there for health promotion projects to implement ideals of community leadership within the realities of marginalisation and inequality? We examine how the Sonagachi Project, a successful sex-worker-led HIV prevention project in India, has engaged with the unequal social relations in which it is embedded. Our ethnographic study is based on observation of the Project's participatory activities and 39 interviews with a range of its stakeholders (including sex worker employees of the Project, non-sex-worker development professionals, brothel managers, sex workers' clients). The analysis shows that the project is deeply shaped by its relationships with non-sex-worker interest groups. In order to be permitted access to the red light district, it has had to accommodate the interests of local men's clubs and brothel managers. The economic and organisational capacity to run such a project has depended upon the direct input of development professionals and funding agencies. Thus, the 'community' that leads this project is much wider than a local grouping of marginalised sex workers. We argue that, given existing power relations, the engagement with other interest groups was necessary to the project's success. Moreover, as the project has developed, sex workers' interests and leadership have gained increasing prominence. We suggest that existing optimistic expectations of participation inhibit acknowledgement of the troubling work of balancing power relations. Rather than denying such power relations, projects should be expected to plan for them.

2013-01-01

Objective To determine whether advocacy targeted at local politicians leads to action to reduce the risk of pedestrian injury in deprived areas. Design Cluster randomised controlled trial. Setting 239 electoral wards in 57 local authorities in England and Wales. Participants 617 elected local politicians. Interventions Intervention group politicians were provided with tailored information packs, including maps of casualty sites, numbers injured and a synopsis of effective interventions. Main outcome measures 25–30 months post intervention, primary outcomes included: electoral ward level: percentage of road traffic calmed; proportion with new interventions; school level: percentage with 20 mph zones, Safe Routes to School, pedestrian training or road safety education; politician level: percentage lobbying for safety measures. Secondary outcomes included politicians’ interest and involvement in injury prevention, and facilitators and barriers to implementation. Results Primary outcomes did not significantly differ: % difference in traffic calming (0.07, 95%CI: −0.07 to 0.20); proportion of schools with 20 mph zones (RR 1.47, 95%CI: 0.93 to 2.32), Safe Routes to School (RR 1.34, 95%CI: 0.83 to 2.17), pedestrian training (RR 1.23, 95%CI: 0.95 to 1.61) or other safety education (RR 1.16, 95%CI: 0.97 to 1.39). Intervention group politicians reported greater interest in child injury prevention (RR 1.09, 95%CI 1.03 to 1.16), belief in potential to help prevent injuries (RR 1.36, 95%CI 1.16 to 1.61), particularly pedestrian safety (RR 1.55, 95%CI 1.19 to 2.03). 63% of intervention politicians reported supporting new pedestrian safety schemes. The majority found the advocacy information surprising, interesting, effectively presented, and could identify suitable local interventions. Conclusions This study demonstrates the feasibility of an innovative approach to translational public health by targeting local politicians in a randomised controlled trial. The intervention package was positively viewed and raised interest but changes in interventions were not statistically significance. Longer term supported advocacy may be needed.

Indirect costs of the interview tour can be prohibitive. The authors sought to assess the desire of interviewees to mitigate these costs through ideas such as sharing hotel rooms and transportation, willingness to stay with local students, and the preferred modality to coordinate this collaboration. A survey link was posted on the Uncle Harvey website and the Facebook profile page of fourth-year medical students from 6 different medical schools shortly after the 2014 match day. There were a total of 156 respondents to the survey. The majority of the respondents were postinterview medical students (65.4%), but preinterview medical students (28.2%) and current residents (6.4%) also responded to the survey. Most respondents were pursuing a field other than neurosurgery (75.0%) and expressed a desire to share a hotel room and/or transportation (77.4%) as well as stay in the dorm room of a medical student at the program in which they are interviewing (70.0%). Students going into neurosurgery were significantly more likely to be interested in sharing hotel/transportation (89.2% neurosurgery vs 72.8% nonneurosurgery; p = 0.040) and in staying in the dorm room of a local student when on interviews (85.0% neurosurgery vs 57.1% nonneurosurgery; p = 0.040) than those going into other specialties. Among postinterview students, communication was preferred to be by private, email identification-only chat room. Given neurosurgery resident candidates' interest in collaborating to reduce interview costs, consideration should be given to creating a system that could allow students to coordinate cost sharing between interviewees. Moreover, interviewees should be connected to local students from neurosurgery interest groups as a resource.

2013-01-01

Introduction Schools are uniquely positioned to influence the dietary habits of children, and farm-to-school programs can increase fruit and vegetable consumption among school-aged children. We assessed the feasibility of, interest in, and barriers to implementing farm-to-school activities in 7 school districts in Douglas County, Nebraska. Methods We used a preassessment and postassessment survey to obtain data from 3 stakeholder groups: school food service directors, local food producers, and food distributors. We had a full-time farm-to-school coordinator who was able to engage multiple stakeholders and oversee the development and dissemination of a toolkit. We used descriptive statistics to make comparisons. Results Seven food service directors, 5 distributors identified by the food service directors, and 57 local producers (9 completed only the preassessment survey, 16 completed only the postassessment survey, and 32 completed both) completed various components of the assessment. Interest in pursuing farm-to-school activities to incorporate more local foods in the school lunch program increased during the 2-year project; mean interest in purchasing local foods by food service directors for their districts increased from 4.4 to 4.7 (on a scale of 1 to 5). Conclusion Implementing farm-to-school programming in Douglas County, Nebraska, is feasible, although food safety and distribution is a main concern among food service directors. Additional research on feasibility, infrastructure, and education is recommended. PMID:24355103

1990-01-01

Community leaders in Atlanta, GA, the Detroit and Lansing, MI, areas, and San Francisco, CA, participated in a demonstration of techniques to disseminate information and increase public awareness of the recommendations from the Surgeon General's Workshop on Drunk Driving, held in December 1988. Local officials worked with the Public Health Service's Office for Substance Abuse Prevention, of the Alcohol, Drug Abuse, and Mental Health Administration, to educate and inform the public about the workshop recommendations as well as other alcohol-related concerns, and to encourage public involvement in their communities with the issue of alcohol-impaired driving and other alcohol-related concerns. With minimal assistance from Federal agencies and Washington-based health and public interest groups, the communities developed unique approaches to generating local television, radio, and newspaper coverage of an event that had originated as national news. The events demonstrated that, with minimal Federal resources and support, local groups can create media attention in conjunction with national news, and local media events can lead to successful community activism. The techniques can be applied by other community groups to gain sufficient news media attention to encourage the public to organize around issues of common concern. PMID:2113684

Fostering supportive community connections through mothers' groups and playgroups.

PubMed

Strange, Cecily; Fisher, Colleen; Howat, Peter; Wood, Lisa

2014-12-01

The aim of this study was to explore the ways that mothers' groups and playgroups support families with children aged 0-5 years and foster community connectedness in newer residential communities in Perth, Western Australia. The transition to parenthood is a time of increased support need. Changing community demography has resulted in a loss of traditional support structures and an increased need for local community initiatives to support families with young children. A qualitative descriptive design was used for this initial phase of a mixed methods sequential exploratory study. Data were collected between December 2011-August 2012. Interviews and focus groups conducted with 39 mothers provided insights from 16 mothers' groups and 13 playgroups. In addition, interviews were undertaken with three child health nurses and four local government early childhood staff. For the participants in this study, mothers' groups and playgroups provided opportunities to learn about parenting, to build a supportive network, to forge friendships and a connectedness to the local community. The families who relocated often experienced isolation until new groups and social networks were found. In general, where participation in mothers' groups and playgroups facilitated relationships with others from the local community, connectedness to that community was reported by participants to be enhanced. Mothers' groups and playgroups provide important community development opportunities and appear to help reduce potential isolation for mothers with young children. The findings are of interest to nurses and other health professionals working with families with young children. © 2014 John Wiley & Sons Ltd.

Strengthening community participation is needed to find solutions to encourage community more participate in reducing Green House Gas (GHG) from forest and peatland fire. This research aimed to identify stakeholders that have the role in forest and peatland fire control and to formulate strengthening model of community participation through community-based early warning fire. Stakeholder mapping and action research were used to determine stakeholders that had potential influence and interest and to formulate strengthening model of community participation in reducing GHG from forest and peatland fire. There was found that position of key players in the mapping of stakeholders came from the government institution. The existence of community-based fire control group can strengthen government institution through collaborating with stakeholders having strong interest and influence. Moreover, it was found several local knowledge in Kapuas District about how communities predict drought that have potential value for developing the community-based early warning fire system. Formulated institutional model in this research also can be further developed as a model institution in the preservation of natural resources based on local knowledge. In conclusion, local knowledge and community-based fire groups can be integrated within strengthening model of community participation in reducing GHG from forest and peatland fire.

The Pacific Northwest's Climate Impacts Group: Climate Science in the Public Interest

NASA Astrophysics Data System (ADS)

Mantua, N.; Snover, A.

2006-12-01

Since its inception in 1995, the University of Washington's Climate Impacts Group (CIG) (funded under NOAA's Regional Integrated Science and Assessments (RISA) Program) has become the leader in exploring the impacts of climate variability and climate change on natural and human systems in the U.S. Pacific Northwest (PNW), specifically climate impacts on water, forest, fish and coastal resource systems. The CIG's research provides PNW planners, decision makers, resource managers, local media, and the general public with valuable knowledge of ways in which the region's key natural resources are vulnerable to changes in climate, and how this vulnerability can be reduced. The CIG engages in climate science in the public interest, conducting original research on the causes and consequences of climate variability and change for the PNW and developing forecasts and decision support tools to support the use of this information in federal, state, local, tribal, and private sector resource management decisions. The CIG's focus on the intersection of climate science and public policy has placed the CIG nationally at the forefront of regional climate impacts assessment and integrated analysis.

Understanding textbook quality in the USA: How governments distort the market

NASA Astrophysics Data System (ADS)

Oliveira, João Batista

1995-11-01

Textbooks deliver education and shape the daily routines of classrooms. Even in countries where schools enjoy ample and various instructional resources, text-books are the single most important support for teachers and students. It is not surprising, then, that textbooks are a major concern of states, schools, teachers, parents, publishers, and the research community. But textbooks often become a scapegoat for educational evils. In the USA, government regulation, special interest groups, and publishers exert pressure on textbook policies and state and local adoption processes. The result: textbooks are published to conform to a market distorted by government regulation. This paper discusses how their quality is constrained by government and special interest groups that interfere with the natural course of regulations and markets.

Scalable Multicast Protocols for Overlapped Groups in Broker-Based Sensor Networks

NASA Astrophysics Data System (ADS)

Kim, Chayoung; Ahn, Jinho

In sensor networks, there are lots of overlapped multicast groups because of many subscribers, associated with their potentially varying specific interests, querying every event to sensors/publishers. And gossip based communication protocols are promising as one of potential solutions providing scalability in P(Publish)/ S(Subscribe) paradigm in sensor networks. Moreover, despite the importance of both guaranteeing message delivery order and supporting overlapped multicast groups in sensor or P2P networks, there exist little research works on development of gossip-based protocols to satisfy all these requirements. In this paper, we present two versions of causally ordered delivery guaranteeing protocols for overlapped multicast groups. The one is based on sensor-broker as delegates and the other is based on local views and delegates representing subscriber subgroups. In the sensor-broker based protocol, sensor-broker might lead to make overlapped multicast networks organized by subscriber's interests. The message delivery order has been guaranteed consistently and all multicast messages are delivered to overlapped subscribers using gossip based protocols by sensor-broker. Therefore, these features of the sensor-broker based protocol might be significantly scalable rather than those of the protocols by hierarchical membership list of dedicated groups like traditional committee protocols. And the subscriber-delegate based protocol is much stronger rather than fully decentralized protocols guaranteeing causally ordered delivery based on only local views because the message delivery order has been guaranteed consistently by all corresponding members of the groups including delegates. Therefore, this feature of the subscriber-delegate protocol is a hybrid approach improving the inherent scalability of multicast nature by gossip-based technique in all communications.

Kgalagadi Transfrontier Park and its land claimants: a pre- and post-land claim conservation and development history

NASA Astrophysics Data System (ADS)

Thondhlana, Gladman; Shackleton, Sheona; Muchapondwa, Edwin

2011-04-01

Kgalagadi Transfrontier Park is located in the Northern Cape Province of South Africa and neighbouring Botswana. The local communities on the South African side, the Khomani San (Bushmen) and Mier living adjacent to the park have land rights inside and outside the park. The path from a history of land dispossession to being land owners has created conservation challenges manifested through heightened inter- and intra-community conflicts. The contestations for land and tourism development opportunities in and outside the park have drawn in powerful institutions such as the governments, South African National Parks, private safari companies, local interest groups and NGOs against relatively powerless local communities. This has consequently attracted national and international interest since it may result in further marginalization of the communities who lack the power to negotiate resource access. Moreover, the social and political system of the San is romanticized while little is reported about the Mier, who are an integral part of the park management system. To make these issues more accessible to a growing audience of interested parties and to better understand present conservation and development challenges and opportunities, this paper synthesizes information on the pre- and post-land restitution history of the park and the adjacent communities.

Amino and Acetamide Functional Group Effects on the Ionization and Fragmentation of Sugar Chains in Positive-Ion Mass Spectrometry

NASA Astrophysics Data System (ADS)

Yamagaki, Tohru; Sugahara, Kohtaro; Watanabe, Takehiro

2014-01-01

To elucidate the influence of amino (-NH2) and acetamide (-NHCOCH3, -NAc) groups in sugar chains on their ionization and fragmentation, cycloamyloses (cyclodextrins, CyDs) and lacto-oligosaccharide are analyzed by MALDI TOF/TOF and ESI Q-TOF mass spectrometry. CyD derivatives substituted by amino or acetamide groups are ideal analytes to extract the function group effects, which are amino-CyD with one hexosamine (HexNH2) and acetamide-CyD with one N-acetyl hexosamine (HexNAc). Interestingly, the relative ion intensities and isotope-like patterns in their product ion spectra depend on the functional groups and ion forms of sugar chains. Consequently, the results indicate that a proton (H+) localizes on the amino group of the amino sugar, and that the proton (H+) induces their fragmentation. Sodium cation (Na+) attachment is independent from amino group and exerts no influence on their fragmentation patterns in amino group except for mono- and disaccharide fragment ions because there is the possibility of the reducing end effect. In contrast, a sodium cation localizes much more frequently on the acetamide group in acetamide-CyDs because the chemical species with HexNAc are stable. Thus, their ions with HexNAc are abundant. These results are consistent with the fragmentation of lacto-neo- N-tetraose and maltotetraose, suggesting that a sodium cation generally localizes much more frequently on the acetamide group in sugar chains.

Stakeholders' Engagement Methods for the Mining Social Responsibility Practice: Determination of Local Issues and Concerns Related to the Mines Operations in Northwest of the US.

NASA Astrophysics Data System (ADS)

Masaitis, A.

2014-12-01

Every year, all around the world, global environmental change affects the human habitat. This is effect enhanced by the mining operation, and creates new challenges in relationship between the mining and local community. The purpose of this project are developed the Stakeholders engagement evaluation plan which is currently developed in University of Nevada, Reno for the Emigrant mining project, located in the central Nevada, USA, and belong to the Newmont Mining Corporation, one of the gold production leader worldwide. The needs for this project is to create the open dialog between Newmont mining company and all interested parties which have social or environmental impacts from the Emigrant mine. Identification of the stakeholders list is first and one of the most difficult steps in the developing of mine social responsibility. Stakeholders' engagement evaluation plan must be based on the timing and available resources of the mining company, understanding the goals for the engagement, and on analyzes of the possible risks from engagement. In conclusion, the Stakeholders engagement evaluation plan includes: first, determinations of the stakeholders list, which must include any interested or effected by the mine projects groups, for example: state and local government representatives, people from local communities, business partners, environmental NGOs, indigenous people, and academic groups. The contacts and availability for communication is critical for Stakeholders engagement. Next, is to analyze characteristics of all these parties and determinate the level of interest and level of their influence on the project. The next step includes the Stakeholders matrix and mapping development, where all these information will be put together.After that, must be chosen the methods for stakeholders' engagement. The methods usually depends from the goals of engagement (create the dialog lines, collect the data, determinations of the local issues and concerns, or establish the negotiation process) and available resources as a time, people, budget. Is it very important here to recognize the possible risks from the engagement and establish the key massage for stakeholders. Finally, the engagement plan should be evaluated and can be implementing for the new social responsibility practice development.

Rank aggregation of local expert knowledge for conservation planning of the critically endangered saola.

Wilkinson, Nicholas M; Van Duc, Luong

2017-06-01

There has been much recent interest in using local knowledge and expert opinion for conservation planning, particularly for hard-to-detect species. Although it is possible to ask for direct estimation of quantities such as population size, relative abundance is easier to estimate. However, an expert's knowledge is often geographically restricted relative to the area of interest. Combining (or aggregating) experts' assessments of relative abundance is difficult when each expert only knows a part of the area of interest. We used Google's PageRank algorithm to aggregate ranked abundance scores elicited from local experts through a rapid rural-appraisal method. We applied this technique to conservation planning for the saola (Pseudoryx nghetinhensis), a poorly known bovid. Near a priority landscape for the species, composed of 3 contiguous protected areas, we asked groups of local people to indicate relative abundances of saola and other species by placing beans on community maps. For each village, we used this information to rank areas within the knowledge area of that village for saola abundance. We used simulations to compare alternative methods to aggregate the rankings from the different villages. The best-performing method was then used to produce a single map of relative abundance across the entire landscape, an area larger than that known to any one village. This map has informed prioritization of surveys and conservation action in the continued absence of direct information about the saola. © 2016 Society for Conservation Biology.

Blindness represents a unique model to study how visual experience may shape the development of brain organization. Exploring how the structure of the corpus callosum (CC) reorganizes ensuing visual deprivation is of particular interest due to its important functional implication in vision (e.g., via the splenium of the CC). Moreover, comparing early versus late visually deprived individuals has the potential to unravel the existence of a sensitive period for reshaping the CC structure. Here, we develop a novel framework to capture a complete set of shape differences in the CC between congenitally blind (CB), late blind (LB) and sighted control (SC) groups. The CCs were manually segmented from T1-weighted brain MRI and modeled by 3D tetrahedral meshes. We statistically compared the combination of local area and thickness at each point between subject groups. Differences in area are found using surface tensor-based morphometry; thickness is estimated by tracing the streamlines in the volumetric harmonic field. Group differences were assessed on this combined measure using Hotelling's T(2) test. Interestingly, we observed that the total callosal volume did not differ between the groups. However, our fine-grained analysis reveals significant differences mostly localized around the splenium areas between both blind groups and the sighted group (general effects of blindness) and, importantly, specific dissimilarities between the LB and CB groups, illustrating the existence of a sensitive period for reorganization. The new multivariate statistics also gave better effect sizes for detecting morphometric differences, relative to other statistics. They may boost statistical power for CC morphometric analyses.

Innovative drug delivery technologies based on smart hydrogels for localized on-demand drug delivery had aroused great interest. To acquire smart UV-crosslinkable chitosan hydrogel for NIR-triggered localized on-demanded drug release, a novel UV-crosslinkable and thermo-responsive chitosan was first designed and synthesized by grafting with poly N-isopropylacrylamide, acetylation of methacryloyl groups and embedding with photothermal carbon. The UV-crosslinkable unit (methacryloyl groups) endowed chitosan with gelation via UV irradiation. The thermo-responsive unit (poly N-isopropylacrylamide) endowed chitosan hydrogel with temperature-triggered volume shrinkage and reversible swelling/de-swelling behavior. The chitosan hybrid hydrogel embedded with photothermal carbon exhibited distinct NIR-triggered volume shrinkage (∼42% shrinkage) in response to temperature elevation as induced by NIR laser irradiation. As a demonstration, doxorubicin release rate was accelerated and approximately 40 times higher than that from non-irradiated hydrogels. The UV-crosslinkable and thermal-responsive hybrid hydrogel served as in situ forming hydrogel-based drug depot is developed for NIR-triggered localized on-demand release.

Use of the wavelet transform to investigate differences in brain PET images between patient groups

Ruttimann, Urs E.; Unser, Michael A.; Rio, Daniel E.; Rawlings, Robert R.

1993-06-01

Suitability of the wavelet transform was studied for the analysis of glucose utilization differences between subject groups as displayed in PET images. To strengthen statistical inference, it was of particular interest investigating the tradeoff between signal localization and image decomposition into uncorrelated components. This tradeoff is shown to be controlled by wavelet regularity, with the optimal compromise attained by third-order orthogonal spline wavelets. Testing of the ensuing wavelet coefficients identified only about 1.5% as statistically different (p < .05) from noise, which then served to resynthesize the difference images by the inverse wavelet transform. The resulting images displayed relatively uniform, noise-free regions of significant differences with, due to the good localization maintained by the wavelets, very little reconstruction artifacts.

Clustering of local group distances: Publication bias or correlated measurements? II. M31 and beyond

2014-07-01

The accuracy of extragalactic distance measurements ultimately depends on robust, high-precision determinations of the distances to the galaxies in the local volume. Following our detailed study addressing possible publication bias in the published distance determinations to the Large Magellanic Cloud (LMC), here we extend our distance range of interest to include published distance moduli to M31 and M33, as well as to a number of their well-known dwarf galaxy companions. We aim at reaching consensus on the best, most homogeneous, and internally most consistent set of Local Group distance moduli to adopt for future, more general use based on themore » largest set of distance determinations to individual Local Group galaxies available to date. Based on a careful, statistically weighted combination of the main stellar population tracers (Cepheids, RR Lyrae variables, and the magnitude of the tip of the red-giant branch), we derive a recommended distance modulus to M31 of (m−M){sub 0}{sup M31}=24.46±0.10 mag—adopting as our calibration an LMC distance modulus of (m−M){sub 0}{sup LMC}=18.50 mag—and a fully internally consistent set of benchmark distances to key galaxies in the local volume, enabling us to establish a robust and unbiased, near-field extragalactic distance ladder.« less

AdS/CFT and local renormalization group with gauge fields

NASA Astrophysics Data System (ADS)

Kikuchi, Ken; Sakai, Tadakatsu

2016-03-01

We revisit a study of local renormalization group (RG) with background gauge fields incorporated using the AdS/CFT correspondence. Starting with a (d+1)-dimensional bulk gravity coupled to scalars and gauge fields, we derive a local RG equation from a flow equation by working in the Hamilton-Jacobi formulation of the bulk theory. The Gauss's law constraint associated with gauge symmetry plays an important role. RG flows of the background gauge fields are governed by vector β-functions, and some of their interesting properties are known to follow. We give a systematic rederivation of them on the basis of the flow equation. Fixing an ambiguity of local counterterms in such a manner that is natural from the viewpoint of the flow equation, we determine all the coefficients uniquely appearing in the trace of the stress tensor for d=4. A relation between a choice of schemes and a virial current is discussed. As a consistency check, these are found to satisfy the integrability conditions of local RG transformations. From these results, we are led to a proof of a holographic c-theorem by determining a full family of schemes where a trace anomaly coefficient is related with a holographic c-function.

Local peoples' knowledge, aptitude, and perceptions of planning and management issues were investigated in Nanda Devi Biosphere Reserve (NDBR) in Uttaranchal State of India. Conflicts ensued between local inhabitants and the management authority due to lack of community participation. Although most respondents seem to claim the knowledge of the objectives of Nanda Devi Biosphere Reserve, the source of information indicates their interaction with the management authority is not frequent. While local population seem to agree on reduced intensity of agriculture with compensation equal to loss of net income, there is a perceptible difference in responses among different age groups. While the younger generation seems to agree to move away to other areas with suitable compensation packages, the older generation prefer those options that require some adjustments in use and access to natural resources. The option of ecotourism as a source of income is acceptable to most respondents, but young and old respondents disagreed about impact of such activity on social behavior of local inhabitants. Among those groups studied, only the "self-employed group" seem to be more interested in ecotourism in comparison to other occupation classes. Gender differences in perceptions are prominent with reference to development options. While the men preferred economic opportunities, the women preferred improved living conditions. An evaluation mechanism similar to the one described in this paper will be helpful to the management authority to assess and modify their management plans to mitigate conflicts with local people.

Surface hydration amplifies single-well protein atom diffusion propagating into the macromolecular core

The effect of surface hydration water on internal protein motion is of fundamental interest in molecular biophysics. Here, by decomposing the picosecond to nanosecond atomic motion in molecular dynamics simulations of lysozyme at different hydration levels into three components localized single-well diffusion, methyl group rotation, and nonmethyl jumps we show that the effect of surface hydration is mainly to increase the volume of the localized single-well diffusion. As a result, these diffusive motions are coupled in such a way that the hydration effect propagates from the protein surface into the dry core.

Travel determinants and multi-scale transferability of national activity patterns to local populations

Henson, Kriste M; Gou; ias, Konstadinos G

The ability to transfer national travel patterns to a local population is of interest when attempting to model megaregions or areas that exceed metropolitan planning organization (MPO) boundaries. At the core of this research are questions about the connection between travel behavior and land use, urban form, and accessibility. As a part of this process, a group of land use variables have been identified to define activity and travel patterns for individuals and households. The 2001 National Household Travel Survey (NHTS) participants are divided into categories comprised of a set of latent cluster models representing persons, travel, and land use.more » These are compared to two sets of cluster models constructed for two local travel surveys. Comparison of means statistical tests are used to assess differences among sociodemographic groups residing in localities with similar land uses. The results show that the NHTS and the local surveys share mean population activity and travel characteristics. However, these similarities mask behavioral heterogeneity that are shown when distributions of activity and travel behavior are examined. Therefore, data from a national household travel survey cannot be used to model local population travel characteristics if the goal to model the actual distributions and not mean travel behavior characteristics.« less

Quantifying density cues in grouping displays.

PubMed

Machilsen, Bart; Wagemans, Johan; Demeyer, Maarten

2016-09-01

Perceptual grouping processes are typically studied using sparse displays of spatially separated elements. Unless the grouping cue of interest is a proximity cue, researchers will want to ascertain that such a cue is absent from the display. Various solutions to this problem have been employed in the literature; however, no validation of these methods exists. Here, we test a number of local density metrics both through their performance as constrained ideal observer models, and through a comparison with a large dataset of human detection trials. We conclude that for the selection of stimuli without a density cue, the Voronoi density metric is preferable, especially if combined with a measurement of the distance to each element's nearest neighbor. We offer the entirety of the dataset as a benchmark for the evaluation of future, possibly improved, metrics. With regard to human processes of grouping by proximity, we found observers to be insensitive to target groupings that are more sparse than the surrounding distractor elements, and less sensitive to regularity cues in element positioning than to local clusterings of target elements.

2007-05-01

I would like to report the effort at Subaru Telescope informing general public what the Subaru is doing and what are the results. The challenge is in two areas, one that our funding agency and the headquarters are in Japan, therefore the distance service in Japanese is a must, while reaching out the local and international community in English is essential in creating awareness that can support our day-to-day operation in the long term. Therefore, the Public Information and Outreach Office at Subaru creates materials in two languages, gives lectures locally in English and remotely in Japanese, and conducts facility tours. Challenge two is the site itself. We have two facilities, one at sea level, the other at the top of Mauna Kea approximately 14,000 feet altitude. The base facility tour mostly accompanies the seminars or lectures held in the facility, including ones for students. The summit tour is offered to the general public via internet registration. Also we do strive to accommodate special requests from groups with specific interests. In the general public tours, we see schoolteachers, amateur astronomers, technically interested people, and people seeking something adventurous. The altitude of the site is a natural obstacle for access, and as a result, we meet very enthusiastic people who are able to overcome logistical challenges. Annual statistics from past years can be summarized as following: * Press release 10 to 20 times 2 languages *Web topics 30 times 2 languages *Summit tour (telescope site) 300+ groups, 1500 to 2000 visitors, including both the general public tours and special/VIP tours. All the facility tours are escorted by Subaru staff. *Base Facility visit by100 groups, as many as1000 participants. *Lectures: remote 15, local 50+ (including a special program of classroom visits), plus some out of the island lectures.

DangerTrack: A scoring system to detect difficult-to-assess regions.

Dolgalev, Igor; Sedlazeck, Fritz; Busby, Ben

2017-01-01

Over recent years, multiple groups have shown that a large number of structural variants, repeats, or problems with the underlying genome assembly have dramatic effects on the mapping, calling, and overall reliability of single nucleotide polymorphism calls. This project endeavored to develop an easy-to-use track for looking at structural variant and repeat regions. This track, DangerTrack, can be displayed alongside the existing Genome Reference Consortium assembly tracks to warn clinicians and biologists when variants of interest may be incorrectly called, of dubious quality, or on an insertion or copy number expansion. While mapping and variant calling can be automated, it is our opinion that when these regions are of interest to a particular clinical or research group, they warrant a careful examination, potentially involving localized reassembly.

Percolation of localized attack on complex networks

2015-02-01

The robustness of complex networks against node failure and malicious attack has been of interest for decades, while most of the research has focused on random attack or hub-targeted attack. In many real-world scenarios, however, attacks are neither random nor hub-targeted, but localized, where a group of neighboring nodes in a network are attacked and fail. In this paper we develop a percolation framework to analytically and numerically study the robustness of complex networks against such localized attack. In particular, we investigate this robustness in Erdős-Rényi networks, random-regular networks, and scale-free networks. Our results provide insight into how to better protect networks, enhance cybersecurity, and facilitate the design of more robust infrastructures.

Efficacy of identifying neural components in the face and emotion processing system in schizophrenia using a dynamic functional localizer.

PubMed

Arnold, Aiden E G F; Iaria, Giuseppe; Goghari, Vina M

2016-02-28

Schizophrenia is associated with deficits in face perception and emotion recognition. Despite consistent behavioural results, the neural mechanisms underlying these cognitive abilities have been difficult to isolate, in part due to differences in neuroimaging methods used between studies for identifying regions in the face processing system. Given this problem, we aimed to validate a recently developed fMRI-based dynamic functional localizer task for use in studies of psychiatric populations and specifically schizophrenia. Previously, this functional localizer successfully identified each of the core face processing regions (i.e. fusiform face area, occipital face area, superior temporal sulcus), and regions within an extended system (e.g. amygdala) in healthy individuals. In this study, we tested the functional localizer success rate in 27 schizophrenia patients and in 24 community controls. Overall, the core face processing regions were localized equally between both the schizophrenia and control group. Additionally, the amygdala, a candidate brain region from the extended system, was identified in nearly half the participants from both groups. These results indicate the effectiveness of a dynamic functional localizer at identifying regions of interest associated with face perception and emotion recognition in schizophrenia. The use of dynamic functional localizers may help standardize the investigation of the facial and emotion processing system in this and other clinical populations.

Although general hypothermia is recognized as a clinically applicable neuroprotective intervention, acute moderate local hypothermia post contusive spinal cord injury (SCI) is being considered a more effective approach. Previously, we have investigated the feasibility and safety of inducing prolonged local hypothermia in the central nervous system of a rodent model. Here, we aimed to verify the efficacy and neuroprotective effects of 5 and 8 hours of local moderate hypothermia (30±0.5°C) induced 2 hours after moderate thoracic contusive SCI in rats. Rats were induced with moderate SCI (12.5 mm) at its T8 section. Local hypothermia (30±0.5°C) was induced 2 hours after injury induction with an M-shaped copper tube with flow of cold water (12°C), from the T6 to the T10 region. Experiment groups were divided into 5-hour and 8-hour hypothermia treatment groups, respectively, whereas the normothermia control group underwent no hypothermia treatment. The neuroprotective effects were assessed through objective weekly somatosensory evoked potential (SSEP) and motor behavior (basso, beattie and bresnahan Basso, Beattie and Bresnahan (BBB) scoring) monitoring. Histology on spinal cord was performed until at the end of day 56. All authors declared no conflict of interest. This work was supported by the Singapore Institute for Neurotechnology Seed Fund (R-175-000-121-733), National University of Singapore, Ministry of Education, Tier 1 (R-172-000-414-112.). Our results show significant SSEP amplitudes recovery in local hypothermia groups starting from day 14 post-injury onward for the 8-hour treatment group, which persisted up to days 28 and 42, whereas the 5-hour group showed significant improvement only at day 42. The functional improvement plateaued after day 42 as compared with control group of SCI with normothermia. This was supported by both 5-hour and 8-hour improvement in locomotion as measured by BBB scores. Local hypothermia also observed insignificant changes in its SSEP latency, as compared with the control. In addition, 5- and 8-hour hypothermia rats' spinal cord showed higher percentage of parenchyma preservation. Early local moderate hypothermia can be induced for extended periods of time post SCI in the rodent model. Such intervention improves functional electrophysiological outcome and motor behavior recovery for a long time, lasting until 8 weeks. Copyright © 2017 Elsevier Inc. All rights reserved.

Haemangiopericytomas are a group of aggressive soft tissue sarcomas that originate from the pericytes in the walls of capillaries. Local invasion of the surrounding structures is not uncommon. Symptoms depend on the location, size and grade of tumour. Coexistence with a benign tumour in the same location is very rare. We report an interesting case of occipital scalp lipoma with an underlying torcular haemangiopericytoma and skull defect. PMID:23761505

Ethnic variations that may influence the preferences and outcomes associated with prostate cancer treatment are not well delineated. Our objective was to evaluate prospectively preferences, optimism, involvement in care, and quality of life (QOL) in black and white veterans newly diagnosed with localized prostate cancer. A total of 95 men who identified themselves as black/African-American or white who had newly diagnosed, localized prostate cancer completed a "time trade-off" task to assess utilities for current health and mild, moderate, and severe functional impairment; importance rankings for attributes associated with prostate cancer (eg, urinary function); and baseline and follow-up measures of optimism, involvement in care, and QOL. Interviews were scheduled before treatment, and at 3 and 12 months after treatment. At baseline, both blacks and whites ranked pain, bowel, and bladder function as their most important concerns. Optimism, involvement in care, and QOL were similar. Utilities for mild impairment were lower for blacks than whites, but were similar for moderate and severe problems. Decline in QOL at 3 and 12 months compared to baseline occurred for both groups. However, even with adjustment for marital status, education level, and treatment, blacks had less increase in nausea and vomiting and more increase in difficulty with sexual interest and weight gain compared with whites. Black and white veterans entered localized prostate cancer treatment with similar priorities, optimism, and involvement in care. Quality-of-life declines were common to both groups during the first year after diagnosis, but ethnic variation occurred with respect to nausea and vomiting, sexual interest, and weight gain.

Recent advances in computing resources have increased interest in systems modeling and population health. While group model building (GMB) has been effectively applied in developing system dynamics models (SD), few studies have used GMB for developing an agent-based model (ABM). This article explores the use of a GMB approach to develop an ABM focused on food insecurity. In our GMB workshops, we modified a set of the standard GMB scripts to develop and validate an ABM in collaboration with local experts and stakeholders. Based on this experience, we learned that GMB is a useful collaborative modeling platform for modelers and community experts to address local population health issues. We also provide suggestions for increasing the use of the GMB approach to develop rigorous, useful, and validated ABMs.

The creation of a new Department of Health in Washington State in 1989 provided an opportunity for analysis of the many forces beyond the pressure of interest groups leading to such a change. Interviews with key actors from executive and legislative branches of state government, local government, and interested health organizations were conducted to uncover the full scope considered for the new department, and the interactions that led to the final, narrower entity. A process model based on these findings is presented as a useful tool for those seeking to improve public health at the state level through changes in the organizational units responsible for health activities.

To meet increasing health demands, increasing the proportion of local graduates entering general practice is imperative. Students entering or exiting The University of Auckland's medical programme from 2006 to 2008 were invited to complete a tracking project survey. Levels of interest in general practice were determined along with characteristics associated with a greater or lesser interest in this career. 712 students replied--a response rate of 80%. At entry, 40% of students had a strong interest in a career in general practice, and at exit, 29% (P =0.003). A quarter at each time point had no interest. The proportion of domestic students born outside NZ or Australia was 160/376 (42.5%). There were significantly higher levels of interest in general practice among females, students born in NZ, and those from outside Auckland--especially rural origin. Flexibility in career was more important to students with a strong interest in general practice than those with no interest. Auckland medical students have levels of interest in general practice comparable with international data. Increasing this interest further may require admission of a greater proportion of students from those groups with higher interest levels, greater emphasis on the positive aspects of general practice, and on GPs as equals to other specialists.

Objective To characterize contemporary attitudes toward global health amongst board-certified obstetricians-gynecologists (Ob-Gyns) in the US. Methods A questionnaire was mailed to members of the American College of Obstetricians and Gynecologists. Respondents were stratified by interest and experience in global health and group differences were reported. Results A total of 202 of 400 (50.5%) surveys were completed; and 67.3% ( n = 136) of respondents expressed an interest in global health while 25.2% ( n = 51) had experience providing healthcare abroad. Personal safety was the primary concern of respondents (88 of 185, 47.6%), with 44.5% (57 of 128) identifying 2 weeks as an optimal period of time to spend abroad. The majority (113 of 186, 60.8%) cited hosting of local physicians in the US as the most valuable service to developing a nation's healthcare provision. Conclusion Despite high interest in global health, willingness to spend significant time abroad was limited. Concerns surrounding personal safety dovetailed with the belief that training local physicians in the US provides the most valuable service to international efforts. These attitudes and concerns suggest novel solutions will be required to increase involvement of Ob-Gyns in global women's health.

A research question was posed to us by a local HIV-resource organization interested in exploring the educational and service needs of those unreached. In order to properly address this inquiry, we developed a community-based participatory research by training peer-led volunteers to facilitate focus-group discussions within Aboriginal and refugees participants following an interview guide. We gathered Aboriginal people and refugees separated into three focus groups each, enrolling a total of 41 self-identified HIV-positive, 38 males. The discussions were tape recorded upon consent and lasted between 59 and 118 minutes. We analyzed the thematic information collected interactively through constant comparison. The qualitative data leading to categories, codes, and themes formed the basis for the spatial representation of a conceptual mapping. Both groups shared similar struggles in living with HIV and in properly accessing local nonmedical HIV resources and discussed their concerns towards the need for empowerment and support to take control of their health.

Vernal pools, a variety of ephemeral wetlands, are threatened in many areas of the United States. As habitat fragmentation and degradation increase, some vernal pool amphibian species are declining in numbers. Uneven implementation of state regulations further hampers effective conservation. To prevent further species decline and vernal pool loss, we evaluated alternatives for improving vernal pool conservation. We used transcripts from a recent vernal pool conference, interviews with members of relevant interest groups, and a literature review to determine opportunities for and constraints on improving vernal pool conservation policy. Participants from different interest groups had very diverse views about appropriate protection strategies. We have examined these different perspectives and alternatives and offer policy recommendations on both the state and local level. These recommendations can foster awareness of vernal pools as unique habitats, increase protection of these areas, and expand citizen participation in the vernal pool regulatory process.

Radical Radiotherapy constitutes a useful therapeutic option for localized prostate cancer. Almost one third of prostate cancer patients choose this alternative to treat the disease. Despite modifications in the technique as intensity modulation, 3D conformational radiotherapy or computer-assisted brachytherapy, a significant percentage of these patients will show an increase in PSA values after radiation. Local relapse without distant disease and PSA less than 10 ng/ml are candidates for salvage therapy. Cryotherapy has already become a curative treatment option in this group of patients. Recent technological as well as surgical advances in salvage-cryotherapy have reduced dramatically complications and progressively increase the interest on this alternative.

Changes in Publication-Based Academic Interest in Local Anesthetics Over the Past 50 Years.

PubMed

Vlassakov, Kamen V; Kissin, Igor

2016-07-01

To present the history of changes in academic interest in local anesthetics quantitatively. The changes in publication-based academic interest in local anesthetics were assessed using information from the database of PubMed. The assessment was mostly based on the following indices: general popularity index (GPI), representing the proportion of articles on a drug relative to all articles in the field of regional anesthesia, and specific popularity index (SPI), representing the proportion of articles on a drug relative to all articles in one of the four forms of regional anesthesia: local anesthesia, spinal anesthesia, epidural anesthesia, and peripheral nerve blocks. The most important general feature of the changes in publication-based academic interest in local anesthetics for the past 50 years was the concentration of this interest on a very limited number of drugs. By 2010-2014, only three anesthetics demonstrated the GPI value above 4.0: bupivacaine (10.1), lidocaine (10.0), and ropivacaine (4.6). All other local anesthetics had GPI declining mostly to less than 1.0 (2010-2014). The rate of change in publication-based academic interest was very slow in both its increase and decline. The most profound change in publication-based academic interests was caused by the introduction of bupivacaine. During a 20-year period (from 1965-1969 to 1985-1989), bupivacaine's GPI increased from 1.3 to 12.9. A slowly developing concentration of publication-based academic interest on a very limited number of local anesthetics was the dominant feature related to this class of anesthetic agents.

Daniels, M.; Kerlin, S.; Arscott, D.

2017-12-01

Citizen-based watershed monitoring has historically lacked scientific rigor and geographic scope due to limitation in access to watershed-level data and the high level skills and resources required to adequately model watershed dynamics. Public access to watershed information is currently routed through a variety of governmental data portals and often requires advanced geospatial skills to collect and present in useable forms. At the same time, tremendous financial resources are being invested in watershed restoration and management efforts, and often these resources pass through local stakeholder groups such as conservation NGO, watershed interest groups, and local municipalities without extensive hydrologic knowledge or access to sophisticated modeling resources. Even governmental agencies struggle to understand how to best steer or prioritize restoration investments. A new app, Model My Watershed, was built to improve access to watershed data and modeling capabilities in a fast, accessible, free web-app format. Working across the contiguous United States, the Model My Watershed app provides land cover, soils, aerial imagery and relief, watershed delineation, and stream network delineation. Users can model watersheds or areas of interest and create management scenarios to evaluate implementation of land cover changes and best management practice implementation with both hydrologic and water quality outputs that meet TMDL regulatory standards.

Stakeholder perspectives on land-use strategies for adapting to climate-change-enhanced coastal hazards: Sarasota, Florida

2010-01-01

Sustainable land-use planning requires decision makers to balance community growth with resilience to natural hazards. This balance is especially difficult in many coastal communities where planners must grapple with significant growth projections, the persistent threat of extreme events (e.g., hurricanes), and climate-change-driven sea level rise that not only presents a chronic hazard but also alters the spatial extent of sudden-onset hazards such as hurricanes. We examine these stressors on coastal, long-term land-use planning by reporting the results of a one-day community workshop held in Sarasota County, Florida that included focus groups and participatory mapping exercises. Workshop participants reflected various political agendas and socioeconomic interests of five local knowledge domains: business, environment, emergency management and infrastructure, government, and planning. Through a series of alternating domain-specific focus groups and interactive plenary sessions, participants compared the county 2050 comprehensive land-use plan to maps of contemporary hurricane storm-surge hazard zones and projected storm-surge hazard zones enlarged by sea level rise scenarios. This interactive, collaborative approach provided each group of domain experts the opportunity to combine geographically-specific, scientific knowledge on natural hazards and climate change with local viewpoints and concerns. Despite different agendas, interests, and proposed adaptation strategies, there was common agreement among participants for the need to increase community resilience to contemporary hurricane storm-surge hazards and to explore adaptation strategies to combat the projected, enlarged storm-surge hazard zones.

Localization of a bacterial group II intron-encoded protein in eukaryotic nuclear splicing-related cell compartments.

Some bacterial group II introns are widely used for genetic engineering in bacteria, because they can be reprogrammed to insert into the desired DNA target sites. There is considerable interest in developing this group II intron gene targeting technology for use in eukaryotes, but nuclear genomes present several obstacles to the use of this approach. The nuclear genomes of eukaryotes do not contain group II introns, but these introns are thought to have been the progenitors of nuclear spliceosomal introns. We investigated the expression and subcellular localization of the bacterial RmInt1 group II intron-encoded protein (IEP) in Arabidopsis thaliana protoplasts. Following the expression of translational fusions of the wild-type protein and several mutant variants with EGFP, the full-length IEP was found exclusively in the nucleolus, whereas the maturase domain alone targeted EGFP to nuclear speckles. The distribution of the bacterial RmInt1 IEP in plant cell protoplasts suggests that the compartmentalization of eukaryotic cells into nucleus and cytoplasm does not prevent group II introns from invading the host genome. Furthermore, the trafficking of the IEP between the nucleolus and the speckles upon maturase inactivation is consistent with the hypothesis that the spliceosomal machinery evolved from group II introns.

Hospitals and local health departments (LHDs) are under policy requirements from the Affordable Care Act and accreditation standards through the Public Health Accreditation Board. Tax exempt hospitals must perform a community health needs assessment (CHNA), similar to the community health assessment (CHA) required for LHDs. These efforts have led to a renewed interest in hospitals and LHDs working together to achieve common goals. The purpose of this study is to gain a better understanding of levels of joint action leading toward collaboration between LHDs and hospitals and describe collaboration around CHAs. Local health departments were selected on the basis of reporting collaboration (n = 26) or unsure about collaboration (n = 29) with local hospitals. Local health departments were surveyed regarding their relationship with local hospitals. For LHDs currently collaborating with a hospital, a collaboration continuum scale was calculated. Appropriate nonparametric tests, chi-squares, and Spearman's rank correlations were conducted to determine differences between groups. A total of 44 LHDs responded to the survey (80.0%). Currently collaborating LHDs were more likely to be interested in accreditation and to refer to their CHA 5 or more times a year compared to the unsure LHDs. In the analysis, a collaboration continuum was created and is positively correlated with aspects of the CHA and CHA process. This study is the first attempt to quantify the level of collaboration between LHDs and hospitals around CHAs. Better understanding of the levels of joint action required may assist LHDs in making informed decisions regarding deployment of resources on the path to accreditation.

This article provides an overview of methods and cross-site insights of a 5-year research and capacity building initiative conducted between 2006 and 2011 in six countries of South Asia (India, Sri Lanka) and South-East Asia (Indonesia, Myanmar, Philippines, Thailand).The initiative managed an interdisciplinary investigation of ecological, biological, and social (i.e., eco-bio-social) dimensions of dengue in urban and peri-urban areas, and developed community-based interventions aimed at reducing dengue vector breeding and viral transmission. The multicountry study comprised interdisciplinary research groups from six leading Asian research institutions. The groups conducted a detailed situation analysis to identify and characterize local eco-bio-social conditions, and formed a community-of-practice for EcoHealth research where group partners disseminated results and collaboratively developed site-specific intervention tools for vector-borne diseases. In sites where water containers produced more than 70% of Aedes pupae, interventions ranged from mechanical lid covers for containers to biological control. Where small discarded containers presented the main problem, groups experimented with solid waste management, composting and recycling schemes. Many intervention tools were locally produced and all tools were implemented through community partnership strategies. All sites developed socially and culturally appropriate health education materials. The study also mobilised and empowered women's, students' and community groups and at several sites organized new volunteer groups for environmental health. The initiative's programmes showed significant impact on vector densities in some sites. Other sites showed varying effect - partially attributable to the 'contamination' of control groups - yet led to significant outcomes at the community level where local groups united around broad interests in environmental hygiene and sanitation. The programme's findings are relevant for defining efficient, effective and ecologically sound vector control interventions based on local evidence and in accordance with WHO's strategy for integrated vector management.

Matching marine reserve design to reserve objectives.

PubMed Central

Halpern, Benjamin S; Warner, Robert R

2003-01-01

Recent interest in using marine reserves for marine resource management and conservation has largely been driven by the hope that reserves might counteract declines in fish populations and protect the biodiversity of the seas. However, the creation of reserves has led to dissension from some interested groups, such as fishermen, who fear that reserves will do more harm than good. These perceived differences in the effect of marine reserves on various stakeholder interests has led to a contentious debate over their merit. We argue here that recent findings in marine ecology suggest that this debate is largely unnecessary, and that a single general design of a network of reserves of moderate size and variable spacing can meet the needs and goals of most stakeholders interested in marine resources. Given the high fecundity of most marine organisms and recent evidence for limited distance of larval dispersal, it is likely that reserves can both maintain their own biodiversity and service nearby non-reserve areas. In particular, spillover of larger organisms and dispersal of larvae to areas outside reserves can lead to reserves sustaining or even increasing local fisheries. Ultimately, the success of any reserve network requires attention to the uncertainty and variability in dispersal patterns of marine organisms, clear statements of goals by all stakeholder groups and proper evaluation of reserve performance.

An artifacts removal post-processing for epiphyseal region-of-interest (EROI) localization in automated bone age assessment (BAA)

PubMed Central

2011-01-01

Background Segmentation is the most crucial part in the computer-aided bone age assessment. A well-known type of segmentation performed in the system is adaptive segmentation. While providing better result than global thresholding method, the adaptive segmentation produces a lot of unwanted noise that could affect the latter process of epiphysis extraction. Methods A proposed method with anisotropic diffusion as pre-processing and a novel Bounded Area Elimination (BAE) post-processing algorithm to improve the algorithm of ossification site localization technique are designed with the intent of improving the adaptive segmentation result and the region-of interest (ROI) localization accuracy. Results The results are then evaluated by quantitative analysis and qualitative analysis using texture feature evaluation. The result indicates that the image homogeneity after anisotropic diffusion has improved averagely on each age group for 17.59%. Results of experiments showed that the smoothness has been improved averagely 35% after BAE algorithm and the improvement of ROI localization has improved for averagely 8.19%. The MSSIM has improved averagely 10.49% after performing the BAE algorithm on the adaptive segmented hand radiograph. Conclusions The result indicated that hand radiographs which have undergone anisotropic diffusion have greatly reduced the noise in the segmented image and the result as well indicated that the BAE algorithm proposed is capable of removing the artifacts generated in adaptive segmentation.

The Quillcapampa la Antigua site in Peru's Sihuas Valley is a settlement from Peru's Middle Horizon (600-100 A.D.). Archaeological interest in the area stems from the question of whether ancient civilizations were able to have extensive state control of distant groups, or whether state influence occurred through less direct ties (e.g., marriage, religion, or trade). Our geophysical surveys are preliminary to archaeological digging in the area. Ground-penetrating radar and magnetometry attempt to locate areas of interest for focused archaeological excavation, characterize the design of architectural remains and burial mounds in the area, and allow archaeologists to interpret the amount of influence the Wari civilization had on the local residents.

Current work highlights the computational aspects of MHD Carreau nanofluid flow over an inclined stretching cylinder with convective boundary conditions and Joule heating. The mathematical modeling of physical problem yields nonlinear set of partial differential equations. A suitable scaling group of variables is employed on modeled equations to convert them into non-dimensional form. The integration scheme Runge-Kutta-Fehlberg on the behalf of shooting technique is utilized to solve attained set of equations. The interesting aspects of physical problem (linear momentum, energy and nanoparticles concentration) are elaborated under the different parametric conditions through graphical and tabular manners. Additionally, the quantities (local skin friction coefficient, local Nusselt number and local Sherwood number) which are responsible to dig out the physical phenomena in the vicinity of stretched surface are computed and delineated by varying controlling flow parameters.

Stakeholder engagement in dredged material management decisions.

Dredging and disposal issues often become controversial with local stakeholders because of their competing interests. These interests tend to manifest themselves in stakeholders holding onto entrenched positions, and deadlock can result without a methodology to move the stakeholder group past the status quo. However, these situations can be represented as multi-stakeholder, multi-criteria decision problems. In this paper, we describe a case study in which multi-criteria decision analysis was implemented in a multi-stakeholder setting in order to generate recommendations on dredged material placement for Long Island Sound's Dredged Material Management Plan. A working-group of representatives from various stakeholder organizations was formed and consulted to help prioritize sediment placement sites for each dredging center in the region by collaboratively building a multi-criteria decision model. The resulting model framed the problem as several alternatives, criteria, sub-criteria, and metrics relevant to stakeholder interests in the Long Island Sound region. An elicitation of values, represented as criteria weights, was then conducted. Results show that in general, stakeholders tended to agree that all criteria were at least somewhat important, and on average there was strong agreement on the order of preferences among the diverse groups of stakeholders. By developing the decision model iteratively with stakeholders as a group and soliciting their preferences, the process sought to increase stakeholder involvement at the front-end of the prioritization process and lead to increased knowledge and consensus regarding the importance of site-specific criteria.

Morphometry Based on Effective and Accurate Correspondences of Localized Patterns (MEACOLP)

Wang, Hu; Ren, Yanshuang; Bai, Lijun; Zhang, Wensheng; Tian, Jie

2012-01-01

Local features in volumetric images have been used to identify correspondences of localized anatomical structures for brain morphometry. However, the correspondences are often sparse thus ineffective in reflecting the underlying structures, making it unreliable to evaluate specific morphological differences. This paper presents a morphometry method (MEACOLP) based on correspondences with improved effectiveness and accuracy. A novel two-level scale-invariant feature transform is used to enhance the detection repeatability of local features and to recall the correspondences that might be missed in previous studies. Template patterns whose correspondences could be commonly identified in each group are constructed to serve as the basis for morphometric analysis. A matching algorithm is developed to reduce the identification errors by comparing neighboring local features and rejecting unreliable matches. The two-sample t-test is finally adopted to analyze specific properties of the template patterns. Experiments are performed on the public OASIS database to clinically analyze brain images of Alzheimer's disease (AD) and normal controls (NC). MEACOLP automatically identifies known morphological differences between AD and NC brains, and characterizes the differences well as the scaling and translation of underlying structures. Most of the significant differences are identified in only a single hemisphere, indicating that AD-related structures are characterized by strong anatomical asymmetry. In addition, classification trials to differentiate AD subjects from NC confirm that the morphological differences are reliably related to the groups of interest. PMID:22540000

To assess the interest of robotic-assisted laparoscopy in the context of deep infiltrating endometriosis and to investigate perioperative results. From November 2008 to April 2012, 164 women with stage IV endometriosis who underwent robotic-assisted laparoscopy (DA VINCI Intuitive Surgical System(®)) were included by eight international participating clinical centers. Patients were divided in 4 groups according to the localization of the nodule(s): rectum (n=88), bladder (n=23), ureter and uterosacral ligaments (n=115) et hysterectomy (n=28). We evaluated the procedures performed, the duration of intervention, the complications, the recurrence and the impact on fertility. In the rectum group, there was a laparotomy conversion, 2 sutured rectal injuries and a red cells blood transfusion. In the bladder group, there was a vesicovaginal hematoma and a prolongated intermittent self-catheterization. In the ureter and uterosacral ligaments group, there was 2 ureteral fistulas and there was no complication in the hysterectomy group. This study is the largest series published in the literature on robotic-assisted laparoscopy for deep infiltrating endometriosis. The interest of robotic-assisted laparoscopy in deep infiltrating endometriosis seems to be promising while no increase in surgical time, blood loss, and intra- and postoperative complications were observed.

Delivering on a gendered definition of health needs in local government budgeting: experiences and concepts.

PubMed

Buyana, K

2009-10-01

Local governments are granted budgetary power in the Local Governments Act of the Republic of Uganda, which allows for local-level participation and flexibility in the allocation of financial grants channelled annually from central to local governments. The act prescribes a legal mandate to allocate public resources based on local priorities including the health needs of women compared with men. This study investigated the responsiveness of local government budgeting to the health needs of women as compared to men. A qualitative study was conducted in Mpigi district using a set of data collection methods including: a) three (3) focus group discussions with 8 female and 8 male respondents in each group; b) face-to-face interviews with a random sample of 120 households, 75% of which were male-headed and 25% female-headed ; c) key informant interviews with a sample of 10 administrative officers in Mpigi district ; and d) desk-review of the Mpigi district Budget Framework Paper. Health needs consist of the daily requirements, which, arise out of common disease infections and the socioeconomic constraints that affect the well-being of women and men. However, the primary concern of the district health sector is disease control measures, without emphasis on the differing socio-economic interests of women as compared to men. Local government budgeting, therefore, does not reflect the broad community-wide understanding of health needs. Local government budgeting should be informed by a two-fold framework for the gendered definition of health needs. The two-fold framework combines both disease-based health needs and socio-economic needs of women as compared to men.

Autonomous vehicles are becoming an essential tool in a wide range of environmental applications that include ambient data acquisition, remote sensing, and mapping of the spatial extent of pollutant spills. Among these applications, pollution source localization has drawn increasing interest due to its scientific and commercial interest and the emergence of a new breed of robotic vehicles capable of operating in harsh environments without human supervision. The aim is to find the location of a region that is the source of a given substance of interest (e.g. a chemical pollutant at sea or a gas leakage in air) using a group of cooperative autonomous vehicles. Motivated by fast paced advances in this challenging area, this paper surveys recent advances in searching techniques that are at the core of environmental monitoring strategies using autonomous vehicles.

The European Commission encourages integrating ecosystem-based approaches in the portfolio of adaptation strategies also in the urban areas. However, the renewed interest in the environmental benefits from green infrastructures coexists with the marginality with which they are treated in practice and, especially, where soil is concerned. Despite its critical functions, soils in cities have often been neglected. In fact, urban soil issues rarely get society attention or even from our policy makers. But, how to make urban soils visible?. From academia we need to extend our communication and networking abilities to engage citizens with projects related to urban soils. Through the Climate-KIC's professional placement programme, Pioneers into Practice, we were able to connect with stakeholders with widely different interests, and engage a broad range of opinions and comments on local circumstances and needs in a semi-quantitative form. Methodology included an actor analysis, an actor network map and a set of semi-structured actor interviews. This involved a local stakeholder network establishment. This stakeholder network reaches out beyond the usual suspects we would expect to partner and it is represented by the following groups: local administration, local governmental services (e.g., forestry and agriculture extension), relevant non-governmental organizations (e.g., dedicated to environment or development) at local level, planners, developers, and individuals (e.g., long-term local residents). The approach is focused on the non-technical barriers to success, whether they are social, institutional, financial, behavioral or regulatory, and how to overcome them. In this context, of a raising environmental awareness, the principal response from interviews demonstrated strong support for a strategic approach to soil management at the urban core and the countryside fringe. Herein, the contribution of urban soils to the provision of ecosystem services, in the framework of the Payments for Ecosystem Services (PES), aroused a great deal of interest among the different stakeholders interviewed. However, the low level of community awareness and understanding of threats to soil natural capital and the long-term consequences of this were also recognized.

Exciton Localization and Optical Emission in Aryl-Functionalized Carbon Nanotubes

Recent spectroscopic studies have revealed the appearance of multiple low-energy peaks in the fluorescence of single-walled carbon nanotubes (SWCNTs) upon their covalent functionalization by aryl groups. The photophysical nature of these low energy optical bands is of significant interest in the quest to understand their appearance and to achieve their precise control via chemical modification of SWCNTs. This theoretical study explains the specific energy dependence of emission features introduced in chemically functionalized (6,5) SWCNTs with aryl bromides at different conformations and in various dielectric media. Calculations using density functional theory (DFT) and time dependent DFT (TD-DFT) show that the specificmore » isomer geometry—the relative position of functional groups on the carbon-ring of the nanotube—is critical for controlling the energies and intensities of optical transitions introduced by functionalization, while the dielectric environment and the chemical composition of functional groups play less significant roles. Furthermore, the predominant effects on optical properties as a result of functionalization conformation are rationalized by exciton localization on the surface of the SWCNT near the dopant sp3-defect but not onto the functional group itself.« less

Network-based analyses of deviant brain function have become extremely popular in psychiatric neuroimaging. Underpinning brain network analyses is the selection of appropriate regions of interest (ROIs). Although ROI selection is fundamental in network analysis, its impact on detecting disease effects remains unclear. We investigated the impact of parcellation choice when comparing results from different studies. We investigated the effects of anatomical (AAL) and literature-based (Dosenbach) parcellation schemes on comparability of group differences in 35 female patients with anorexia nervosa and 35 age- and sex-matched healthy controls. Global and local network properties, including network-based statistics (NBS), were assessed on resting state functional magnetic resonance imaging data obtained at 3T. Parcellation schemes were comparably consistent on global network properties, while NBS and local metrics differed in location, but not metric type. Location of local metric alterations varied for AAL (parietal and cingulate cortices) versus Dosenbach (insula, thalamus) parcellation approaches. However, consistency was observed for the occipital cortex. Patient-specific global network properties can be robustly observed using different parcellation schemes, while graph metrics characterizing impairments of individual nodes vary considerably. Therefore, the impact of parcellation choice on specific group differences varies depending on the level of network organization. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The Impact of an Informal Science Program on Students' Science Knowledge and Interest

NASA Astrophysics Data System (ADS)

Zandstra, Anne Maria

In this sequential explanatory mixed methods study, quantitative and qualitative data were used to measure the impact of an informal science program on eleventh grade students' science knowledge and interest. The local GEAR UP project has been working for six years with a cohort of students who were in eleventh and twelfth grade during the time of the study. Participants of this study were 122 eleventh grade students from this cohort. In the first, quantitative phase, state standardized test scores and a modified version of the Test of Science Related Attitudes (TOSRA) were used to measure participants' science knowledge and interest respectively. The findings of the quantitative phase revealed a small but significant correlation between students' attendance at the program elements (in total number of hours) and their science knowledge. In addition, small but significant correlations were found between (1) students' attendance at the mathematics program element and their total interest scores, (2) their mathematics attendance and the career interest subscore, and (3) their total attendance and the normality of scientist subscore. The qualitative data in the second phase consisted of focus group interviews with fourteen of the participants. Results of this phase showed that the majority of the focus group participants agreed that they had learned something from the GEAR UP field trips and half of them thought the field trips had impacted their grades and test scores. Furthermore, a majority of the focus group participants concurred that their experiences in the field trips had increased their interest in science. The purpose of the qualitative phase of this study was to provide explanations for the results of the quantitative phase. Explanations for the correlation between attendance and knowledge were that the field trips covered the same content as the formal science classes and that students learned more because they perceived the field trips as fun and hands-on. The correlations between attendance and interest were explained by the fact that students had the opportunity to see interesting aspects of science and interact with real scientists during the field trips.

Functional equations for orbifold wreath products

NASA Astrophysics Data System (ADS)

Farsi, Carla; Seaton, Christopher

2017-10-01

We present generating functions for extensions of multiplicative invariants of wreath symmetric products of orbifolds presented as the quotient by the locally free action of a compact, connected Lie group in terms of orbifold sector decompositions. Particularly interesting instances of these product formulas occur for the Euler and Euler-Satake characteristics, which we compute for a class of weighted projective spaces. This generalizes results known for global quotients by finite groups to all closed, effective orbifolds. We also describe a combinatorial approach to extensions of multiplicative invariants using decomposable functors that recovers the formula for the Euler-Satake characteristic of a wreath product of a global quotient orbifold.

Aim of the study: Investigation, whether water-filtered infrared-A (wIRA) irradiation during moderate bicycle ergometer endurance exercise has effects especially on local fat reduction and on weight reduction beyond the effects of ergometer exercise alone. Methods: Randomised controlled study with 40 obese females (BMI 30-40 (median: 34.5), body weight 76-125 (median: 94.9) kg, age 20-40 (median: 35.5) years, isocaloric nutrition), 20 in the wIRA group and 20 in the control group. In both groups each participant performed 3 times per week over 4 weeks for 45 minutes bicycle ergometer endurance exercise with a constant load according to a lactate level of 2 mmol/l (aerobic endurance load, as determined before the intervention period). In the wIRA group in addition large parts of the body (including waist, hip, and thighs) were irradiated during all ergometries of the intervention period with visible light and a predominant part of water-filtered infrared-A (wIRA), using the irradiation unit “Hydrosun® 6000” with 10 wIRA radiators (Hydrosun® Medizintechnik, Müllheim, Germany, radiator type 500, 4 mm water cuvette, yellow filter, water-filtered spectrum 500-1400 nm) around a speed independent bicycle ergometer. Main variable of interest: change of “the sum of circumferences of waist, hip, and both thighs of each patient” over the intervention period (4 weeks). Additional variables of interest: body weight, body mass index BMI, body fat percentage, fat mass, fat-free mass, water mass (analysis of body composition by tetrapolar bioimpedance analysis), assessment of an arteriosclerotic risk profile by blood investigation of variables of lipid metabolism (cholesterol, triglycerides, high density lipoproteins HDL, low density lipoproteins LDL, apolipoprotein A1, apolipoprotein B), clinical chemistry (fasting glucose, alanin-aminotransferase ALT (= glutamyl pyruvic transaminase GPT), gamma-glutamyl-transferase GGT, creatinine, albumin), endocrinology (leptin, adiponectin (= adipo Q), homocysteine, insulin). All variables were at least measured before and after the intervention period. Ergometry (ECG, blood pressure behaviour, lactate curve with power at 2, 3 and 4 mmol/l) before the intervention period. In addition: nutrition training ahead of and during the intervention period with a nutrition protocol over one week for assessment of the daily energy intake; calculation of basic metabolic rate and total energy requirement. Assessment of undesired effects. Only methods of non-parametric statistics were used, both descriptive (median, percentiles of 25 and 75 (= interquartile range), minimum, maximum) and confirmatory (two-sided Mann-Whitney U test for unpaired samples for the only one main variable of interest). Total error probability: .05 (5%). An intention to treat analysis ITT with last observed carry forward method was used preferably (presented results) and in addition an on treatment analysis OT. Only 2 (treatment group) and 4 (control group) drop-outs occurred (mostly due to lack of time). Results: The “sum of circumferences of waist, hip, and both thighs of each patient” decreased during the 4 weeks significantly more (p<.001) in the wIRA group than in the control group: medians and interquartile ranges: -8.0 cm (-10.5 cm/-4.1 cm) vs. -1.8 cm (-4.4 cm/0.0 cm). As well “body weight of each patient” decreased during the 4 weeks markedly more in the wIRA group than in the control group: medians and interquartile ranges: -1.9 kg (-4.0 kg/0.0 kg) vs. 0.0 kg (-1.5 kg/+0.4 kg); median of body weight changed from 99.3 kg to 95.6 kg (wIRA) vs. 89.9 kg to 89.6 kg (control). A similar effect showed the body mass index BMI. Blood variables of interest remained unchanged or showed some slight improvements during the treatment period, concerning most variables with no obvious differences between the two groups; insulin showed a slight trend to decrease in the wIRA group and to increase in the control group. Undesired effects of the treatment were not seen. Discussion: The results of the study suggest, that wIRA – during moderate bicycle ergometer endurance exercise as lipolytic stimulus – increases local lipolysis with a local fat reduction (thighs) in the otherwise bradytrophic fatty tissue. The presumably underlying mechanisms of wIRA have already been proven: wIRA acts both by thermal effects and by non-thermal effects. Thermal effects of wIRA are the generation of a therapeutic field of warmth with the increase of tissue temperature, tissue oxygen partial pressure, and tissue blood flow, and by this regional metabolism. As fatty tissue normally has a slow metabolism (bradytrophic and hypothermic tissue) with a low rate of lipolysis, wIRA can increase lipolysis in fatty tissue and the mobilized fats are burned in musculature during the ergometer exercise. Conclusion: The results of the study indicate, that wIRA irradiation during moderate ergometer endurance exercise can be used – in combination with an appropriate nutrition – to improve body composition, especially local fat distribution, and the reduction of fat and body weight in obese persons.

We demonstrate an analytical prescription of demonstrating the flat band [FB] states in a fractal incorporated kagomé type network that can give rise to a countable infinity of flat non-dispersive eigenstates with a multitude of localization area. The onset of localization can, in principle, be delayed in space by an appropriate choice of energy regime. The length scale, at which the onset of localization for each mode occurs, can be tuned at will following the formalism developed within the framework of real space renormalization group. This scheme leads to an exact determination of energy eigenvalue for which one can havemore » dispersionless flat electronic bands. Furthermore, we have shown the effect ofuniform magnetic field for the same non-translationally invariant network model that has ultimately led to an‘apparent invisibility’ of such staggered localized states and to generate absolutely continuous sub-bands in the energy spectrum and again an interesting re-entrant behavior of those FB states.« less

Local Kernel for Brains Classification in Schizophrenia

NASA Astrophysics Data System (ADS)

Castellani, U.; Rossato, E.; Murino, V.; Bellani, M.; Rambaldelli, G.; Tansella, M.; Brambilla, P.

In this paper a novel framework for brain classification is proposed in the context of mental health research. A learning by example method is introduced by combining local measurements with non linear Support Vector Machine. Instead of considering a voxel-by-voxel comparison between patients and controls, we focus on landmark points which are characterized by local region descriptors, namely Scale Invariance Feature Transform (SIFT). Then, matching is obtained by introducing the local kernel for which the samples are represented by unordered set of features. Moreover, a new weighting approach is proposed to take into account the discriminative relevance of the detected groups of features. Experiments have been performed including a set of 54 patients with schizophrenia and 54 normal controls on which region of interest (ROI) have been manually traced by experts. Preliminary results on Dorso-lateral PreFrontal Cortex (DLPFC) region are promising since up to 75% of successful classification rate has been obtained with this technique and the performance has improved up to 85% when the subjects have been stratified by sex.

Systematizing the production of environmental plans: an Australian example

NASA Astrophysics Data System (ADS)

Davis, J. Richard

1985-09-01

Environmental planning legislation in New South Wales now requires local government authorities to draw up statutory plans that take into account, among other concerns, both the biophysical and the social environmental issues within their jurisdictions. The SIRO-PLAN method of plan production provides a systematic mechanism for fulfilling this requirement. This article describes the application of the method by planning researchers over 18 months to the production of a Local Environmental Plan for a rural local government in New South Wales. The policy formulation, the purposive data collection, and the deliberate adjustment of plans in order to recognize interest group requirements were all found to be valuable features of the method, while the translation of the ultimately chosen land-use plan into the explicit regulatory controls available to the local government authority was found to require further refinement. The capacity of SIRO-PLAN to quantify the resolution of competing environmental concerns in the final plan, although of value to planning researchers, proved too arcane for traditionally trained planners.

A public health project is described which used social marketing philosophy and techniques to find out how to help facilitate breast-feeding in public places and for mothers returning to work. As part of a strategy to increase local breast-feeding rates, Brighton and Hove Healthy City Partnership, representing the local Primary Care Trust, City Council and the business, academic and voluntary sectors, worked with a social marketing consultancy. The consultancy carried out a literature review and qualitative research that used creative engagement methods to consult with local people. The consultations were with key stakeholders, mothers, and groups traditionally less interested in the subject of breast-feeding, such as employers, elderly people, teenage boys, and fathers. The qualitative research generated in-depth insight and soundly-based, practical recommendations for facilitating breast-feeding. The social marketing approach helped to establish that any ensuing policies and practices would be acceptable to a wide range of the local population.

The dynamic nature of tissue temperature and the subcutaneous properties, such as blood flow, fatness, and metabolic rate, leads to variation in local skin temperature. Therefore, we investigated the effects of using multiple regions of interest when calculating weighted mean skin temperature from four local sites. Twenty-six healthy males completed a single trial in a thermonetural laboratory (mean ± SD): 24.0 (1.2)°C; 56 (8%) relative humidity; <0.1 m/s air speed). Mean skin temperature was calculated from four local sites (neck, scapula, hand and shin) in accordance with International Standards using digital infrared thermography. A 50 mm × 50 mm, defined by strips of aluminium tape, created six unique regions of interest, top left quadrant, top right quadrant, bottom left quadrant, bottom right quadrant, centre quadrant and the entire region of interest, at each of the local sites. The largest potential error in weighted mean skin temperature was calculated using a combination of a) the coolest and b) the warmest regions of interest at each of the local sites. Significant differences between the six regions interest were observed at the neck (P<0.01), scapula (P<0.001) and shin (P<0.05); but not at the hand (P = 0.482). The largest difference (± SEM) at each site was as follows: neck 0.2 (0.1)°C; scapula 0.2 (0.0)°C; shin 0.1 (0.0)°C and hand 0.1 (0.1)°C. The largest potential error (mean ± SD) in weighted mean skin temperature was 0.4 (0.1)°C (P<0.001) and the associated 95% limits of agreement for these differences was 0.2-0.5 °C. Although we observed differences in local and mean skin temperature based on the region of interest employed, these differences were minimal and are not considered physiologically meaningful.

Localization of charge carriers in crystalline solids has been the subject of numerous investigations over more than half a century. Materials that show a metal-insulator transition without a structural change are therefore of interest. Mechanisms leading to metal-insulator transition include electron correlation (Mott transition) or disorder (Anderson localization), but a clear distinction is difficult. Here we report on a metal-insulator transition on increasing annealing temperature for a group of crystalline phase-change materials, where the metal-insulator transition is due to strong disorder usually associated only with amorphous solids. With pronounced disorder but weak electron correlation, these phase-change materials form an unparalleled quantum state of matter. Their universal electronic behaviour seems to be at the origin of the remarkable reproducibility of the resistance switching that is crucial to their applications in non-volatile-memory devices. Controlling the degree of disorder in crystalline phase-change materials might enable multilevel resistance states in upcoming storage devices.

Qualitative data that explored the connection between salmon and well-being were collected and collaboratively reviewed with a community work group and analyzed using thematic analysis. Findings were used to co-design the nutrition intervention. Formative research Thndings and ongoing collaboration between academic and community partners informed the Thnal intervention design. Because people's behaviors and interactions with culturally signiThcant foods are embedded in cultural perceptions and local contexts, it is important for nutrition interventions to address local perceptions of these foods.

Friends-of-friends galaxy group finder with membership refinement. Application to the local Universe

Context. Groups form the most abundant class of galaxy systems. They act as the principal drivers of galaxy evolution and can be used as tracers of the large-scale structure and the underlying cosmology. However, the detection of galaxy groups from galaxy redshift survey data is hampered by several observational limitations. Aims: We improve the widely used friends-of-friends (FoF) group finding algorithm with membership refinement procedures and apply the method to a combined dataset of galaxies in the local Universe. A major aim of the refinement is to detect subgroups within the FoF groups, enabling a more reliable suppression of the fingers-of-God effect. Methods: The FoF algorithm is often suspected of leaving subsystems of groups and clusters undetected. We used a galaxy sample built of the 2MRS, CF2, and 2M++ survey data comprising nearly 80 000 galaxies within the local volume of 430 Mpc radius to detect FoF groups. We conducted a multimodality check on the detected groups in search for subgroups. We furthermore refined group membership using the group virial radius and escape velocity to expose unbound galaxies. We used the virial theorem to estimate group masses. Results: The analysis results in a catalogue of 6282 galaxy groups in the 2MRS sample with two or more members, together with their mass estimates. About half of the initial FoF groups with ten or more members were split into smaller systems with the multimodality check. An interesting comparison to our detected groups is provided by another group catalogue that is based on similar data but a completely different methodology. Two thirds of the groups are identical or very similar. Differences mostly concern the smallest and largest of these other groups, the former sometimes missing and the latter being divided into subsystems in our catalogue. The catalogues are available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/588/A14

No evidence of a clinically important effect of adding local infusion analgesia administrated through a catheter in pain treatment after total hip arthroplasty

PubMed Central

2011-01-01

Background and purpose Postoperative analgesia after primary total hip arthroplasty (THA) using opioids is associated with troublesome side effects such as nausea and dizziness, and epidural analgesic means delayed mobilization. Thus, local infiltration analgesia (LIA) during surgery prolonged with local infusion analgesia (LINFA) into the soft tissue in the hip region through a catheter in the first postoperative days has gained major interest in THA fast-track settings within a short period of time. LIA at the time of surgery is a validated treatment. We investigated the additional effect of giving postoperative LINFA after THA in patients already having LIA during surgery. Patients and methods 60 consecutive patients undergoing non-cemented THA were randomized into two groups in a double-blind and controlled study. During surgery, all patients received standardized pain treatment with LIA. Postoperatively, they were treated either with a solution of Ropivacain, Ketorolac, and Adrenaline (LINFA group) or placebo (placebo group) administered through a catheter to the hip 10 and 22 h after surgery. Pain score, opioid consumption, and length of stay (LOS) were evaluated. Results After adjustment for multiple testing, there was no statistically significant postoperative difference between the LINFA group and the placebo group regarding pain and tiredness. We found some evidence of a short-term effect on nausea and vomiting. Opioid consumption and length of stay were similar in the two groups. Interpretation We found some evidence of a short-term effect of LINFA on nausea and vomiting, but no evidence of an effect on postoperative pain and tiredness. Thus, LINFA cannot be recommended as a standard pain treatment in patients with THA. PMID:21619503

To examine the involvement of stakeholders in the implementation of a local policy of integrative practices. Qualitative study conducted in the city of Recife, Northeastern Brazil. Data was collected from local health board records between 2004 and 2009, interviews with managers and key informants and focus groups with providers and users. The analysis was performed using the condensation of meaning model. The results were grouped into four categories of stakeholders according to their influence and interest, namely: subjects; population; leaders; and players. Five years after the policy was implemented in Recife, only a single service offered integrative practices. The population, or users, did not have any effective involvement and did not make any contributions to the policy, and health providers, despite their willingness to participate in the process, were not involved. The leaders included the local health board, managers and medical organizations; the latter two were also players as they were effectively involved in the formulation of the policy. The involvement of few stakeholders in the formulation of an integrative practice policy makes it difficult its implementation and widens the gap between formulation and implementation, hindering the achievement of expected results.

Spatial cognition in autism spectrum disorders: superior, impaired, or just intact?

PubMed

Edgin, Jamie O; Pennington, Bruce F

2005-12-01

The profile of spatial ability is of interest across autism spectrum disorders (ASD) because of reported spatial strengths in ASD and due to the recent association of Asperger's syndrome with Nonverbal Learning Disability. Spatial functions were examined in relation to two cognitive theories in autism: the central coherence and executive function (EF) theories. Performance on spatial tasks, EFs, and global/local processing was compared in children with ASD and controls. While the ASD group had faster reaction times on the Embedded Figures task, spatial performance was intact, but not superior, on other tasks. There was no evidence for impairments in EF or in processing global/local information, therefore contradicting these two theories. The implications of these results for these two theories are discussed.

Public participation in the development of flood risk management and river basin management plans are explicit components of both the Water Framework and Floods Directives. At the local level, involving communities in land and water management has been found to (i) aid better environmental decision making, (ii) enhance social, economic and environmental benefits, and (iii) increase a sense of ownership. Facilitating the access and exchange of information on the local environment is an important part of this new approach to the land and water management process, which also includes local community stakeholders in decisions about the design and content of the information provided. As part of the Natural Environment Research Council's pilot Environment Virtual Observatory (EVO), the Local Level group are engaging with local community stakeholders in three different catchments in the UK (the rivers Eden, Tarland and Dyfi) to start the process of developing prototype visualisation tools to address the specific land and water management issues identified in each area. Through this local collaboration, we will provide novel visualisation tools through which to communicate complex catchment science outcomes and bring together different sources of environmental data in ways that better meet end-user needs as well as facilitate a far broader participatory approach in environmental decision making. The Local Landscape Visualisation Tools are being evolved iteratively during the project to reflect the needs, interests and capabilities of a wide range of stakeholders. The tools will use the latest concepts and technologies to communicate with and provide opportunities for the provision and exchange of information between the public, government agencies and scientists. This local toolkit will reside within a wider EVO platform that will include national datasets, models and state of the art cloud computer systems. As such, local stakeholder groups are assisting the EVO's development and participating in local decision making alongside policy makers, government agencies and scientists.

To investigate and localize the sources of spontaneous, scalp-recorded theta activity in patients with partial epilepsy (PE). Nine patients with beginning, untreated PE (Group 1), 31 patients with already treated PE (Group 2), and 14 healthy persons were investigated by means of spectral analysis and LORETA, low resolution electromagnetic tomography (1 Hz very narrow band analysis, age-adjusted, Z-scored values). The frequency of main interest was 4-8 Hz. Group analysis: Group 1 displayed bilateral theta maxima in the temporal theta area (TTA), parietal theta area (PTA), and frontal theta area (FTA). In Group 2, theta activity increased all over the scalp as compared to the normative mean (Z=0) and also to Group 1. Maximum activity was found in the TTA, PTA, and FTA. However, in the PTA and FTA the centers of the abnormality shifted towards the medial cortex. Individual analysis: all the patients showed preferential activation (maximum Z-values) within one of the three theta areas. EEG activity in the theta band is increased in anatomically meaningful patterns in PE patients, which differs from the anatomical distribution of theta in healthy persons. The findings contribute to our understanding of the sources of theta rhythms and the pathophysiology of PE. Copyright 2010 International Federation of Clinical Neurophysiology.

Background We explored rural African American youths' perceptions about the role of community social institutions in addressing HIV. Methods We conducted four focus groups with African Americans aged 16 to 24 years in two rural counties in North Carolina. Groups were stratified by gender and risk status. We used a grounded theory approach to content analysis. Results Participants identified four social institutions as primary providers of HIV-related health promotion efforts: faith organizations, schools, politicians, and health agencies. They reported perceiving a lack of involvement in HIV prevention by faith-based organizations, constraints of abstinence-based sex education policies, politicians' lack of interest in addressing broader HIV determinants, and inadequacies in health agency services, and viewed all of these as being counter-productive to HIV prevention efforts. Conclusions youth have important insights about local social institutions that should be considered when designing HIV prevention interventions that partner with local organizations. PMID:20453373

This paper describes a Group Model Building (GMB) initiative that was designed to discuss the various potential effects that an offshore wind-farm may have on its local ecology and socioeconomic development. The representatives of various organizations in the study area, Lu-Kang, Taiwan, have held several meetings, and structured debates have been organized to promote the emergence of a consensual view on the main issues and their implications. A System Dynamics (SD) model has been built and corrected iteratively with the participants through the GMB process. The diverse interests within the group led the process toward the design of multifunctional wind-farms with different modalities. The scenario analyses, using the SD model under various policies, including no wind-farm policy, objectively articulates the vision of the local stakeholders. The results of the SD simulations show that the multifunctional wind-farms may have superior economic effects and the larger wind-farms with bird corridors could reduce ecological impact. However, the participants of the modeling process did not appreciate any type of offshore wind-farm development when considering all of the identified key factors of social acceptance. The insight gained from the study can provide valuable information to actualize feasible strategies for the green energy technique to meet local expectations. Copyright © 2012 Elsevier B.V.

STAR FORMATION IN DWARF GALAXIES OF THE NEARBY CENTAURUS A GROUP

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cote, Stephanie; Draginda, Adam; Skillman, Evan D.

2009-10-15

We present H{alpha} narrow-band imaging of 17 dwarf irregular (dI) galaxies in the nearby Centaurus A Group. Although all large galaxies of the group are or recently have been through a period of enhanced star formation, the dIs have normal star formation rates (SFRs) and do not contain a larger fraction of dwarf starbursts than other nearby groups such as the Sculptor Group or the Local Group. Most of the galaxies in the group now have fairly accurately known distances, which enables us to obtain relative distances between dIs and larger galaxies of the group. We find that the dImore » SFRs do not depend on local environment, and in particular they do not show any correlation with the distance of the dI to the nearest large galaxy of the group. There is a clear morphology-density relation in the Centaurus A Group, similar to the Sculptor Group and Local Group, in the sense that dwarf ellipticals (dEs)/dwarf spheroidals (dSphs) tend to be at small distances from the more massive galaxies of the group, while dIs are on average at larger distances. We find four transition dwarfs in the Group, dwarfs that show characteristics of both dE/dSphs and dIs, and which contain cold gas but no current star formation. Interestingly, the transition dwarfs have an average distance to the more massive galaxies, which is intermediate between those of the dEs/dSphs and dIs and which is quite large: 0.54 {+-} 0.31 Mpc. This large distance poses some difficulty for the most popular scenarios proposed for transforming a dI into a dE/dSph (ram-pressure with tidal stripping or galaxy harassment). If the observed transition dwarfs are indeed missing links between dIs and dE/dSphs, their relative isolation makes it less likely to have been produced by these mechanisms. An inhomogeneous intergalactic medium containing higher density clumps would be able to ram-pressure strip the dIs at larger distances from the more massive galaxies of the group.« less

Background Positive "dynamic spot sign" has been proven to be a potential risk factor for acute intracerebral hemorrhage (ICH) expansion, but local perfusion change has not been quantitatively investigated. Purpose To quantitatively evaluate perfusion changes at the ICH area using computed tomography perfusion (CTP) imaging. Material and Methods Fifty-three patients with spontaneous ICH were recruited. Unenhanced computed tomography (NCCT), CTP within 6 h, and follow-up NCCT were performed for 21 patients in the "spot sign"-positive group and 32 patients in the control group. Cerebral perfusion change was quantitatively measured on regional cerebral blood flow/regional cerebral blood volume (rCBF/rCBV) maps. Regions of interest (ROIs) were set at the "spot-sign" region and the whole hematoma area for "spot-sign"-positive cases, and at one of the highest values of three interested areas and the whole hematoma area for the control group. Hematoma expansion was determined by follow-up NCCT. Results For the "spot-sign"-positive group, the average rCBF (rCBV) values at the "spot-sign" region and the whole hematoma area were 21.34 ± 15.24 mL/min/100 g (21.64 ± 21.48 mL/100g) and 5.78 ± 6.32 mL/min/100 g (6.07 ± 5.45 mL/100g); for the control group, the average rCBF (rCBV) values at the interested area and whole hematoma area were 2.50 ± 1.83 mL/min/100 g (3.13 ± 1.96 mL/100g) and 3.02 ± 1.80 mL/min/100 g (3.40 ± 1.44 mL/100g), respectively. Average rCBF and rCBV values of the "spot-sign" region were significantly different from other regions ( P < 0.001; P = 0.004). The average volumes of hematoma expansion in the "spot-sign"-positive and control groups were 25.24 ± 19.38 mL and -0.41 ± 1.34 mL, respectively. Conclusion The higher perfusion change at ICH on CTP images may reflect the contrast extravasation and be associated with the hematoma expansion.

Following the Safe and Sustainable review of Paediatric Services in 2012/2013, National Health Service England recommended that local paediatric cardiology services should be provided by specially trained paediatricians with expertise in cardiology in all non-specialist hospitals. To understand the variation in local paediatric cardiology services provided across district general hospitals in the United Kingdom. An internet-based questionnaire was sent out via the Paediatrician with Expertise in Cardiology Special Interest Group and the Neonatologists with Interest in Cardiology and Haemodynamics contact databases and the National Health Service directory. Non-responders were followed-up via telephone. The response rate was 80% (141 of 177 hospitals), and paediatricians with expertise in cardiology were available in 68% of those. Local cardiology clinics led by paediatricians with expertise in cardiology were provided in 96 hospitals (68%), whereas specialist outreach clinics were held in 123 centres (87%). A total of 11 hospitals provided neither specialist outreach clinics nor any local cardiology clinics led by paediatricians with expertise in cardiology. Paediatric echocardiography services were provided in 83% of the hospitals, 12-lead electrocardiogram in 96%, Holter electrocardiogram in 91%, and exercise testing in only 47% of the responding hospitals. Telemedicine facilities were established in only 52% of the centres, where sharing echocardiogram images via picture archiving and communication system was used most commonly. There has been a substantial increase in the availability of paediatricians with expertise in cardiology since 2008. Most of the hospitals are well-supported by specialist cardiology centres via outreach clinics; however, there remains significant variation in the local paediatric cardiology services provided across district general hospitals in the United Kingdom.

The exact alterations of the immune system after polytrauma leading to sepsis and multiple-organ failure are poorly understood. Thus, the early local and systemic inflammatory and apoptotic response was characterized in a new polytrauma model and compared with the alterations seen after single or combined injuries. Anesthetized C57BL/6 mice were subjected to either blunt bilateral chest trauma (Tx), closed head injury, right femur fracture including contralateral soft tissue injury, or a combination of injuries (PTx). After 2 hours or 6 hours, animals were sacrificed, and the systemic as well as the local pulmonary immune response (bronchoalveolar lavage [BAL]/plasma cytokines, lung myeloperoxidase [MPO] activity, and alveolocapillary barrier dysfunction) were evaluated along with lung/brain apoptosis (lung caspase 3 Western blotting, immunohistochemistry, and polymorphonuclear leukocytes [PMN] Annexin V). Hemoglobin, PO2 saturation, and pH did not differ between the experimental groups. Local BAL cytokines/chemokines were significantly increased in almost all groups, which included Tx. There was no further enhancement of this local inflammatory response in the lungs in case of PTx. At 2 hours, all groups except sham and closed head injury alone revealed an increased activity of lung MPO. However, 6 hours after injury, lung MPO remained increased only in the PTx group. Increased BAL protein levels were found, reflecting enhanced lung leakage in all groups with Tx 6 hours after trauma. Only after PTx was neutrophil apoptosis significantly decreased, whereas lung caspase 3 and plasma interleukin 6/keratinocyte chemoattractant (KC) were substantially increased. The combination of different injuries leads to an earlier systemic inflammatory response when compared with the single insults. Interestingly, only after PTx but not after single or double hits was lung apoptosis increased, and PMN apoptosis was decreased along with a prolonged presence of neutrophils in the lungs, which may therefore represent a possible pathomechanism for lung injury after polytrauma.

*INTRODUCTION AND ACKNOWLEDGMENTS* Karst aquifer systems are present throughout parts of the United States and some of its territories. The complex depositional environments that form carbonate rocks combined with post-depositional tectonic events and the diverse climatic regimes under which these rocks were formed result in unique hydrologic systems. The dissolution of calcium carbonate and the subsequent development of distinct and beautiful landscapes, caverns, and springs have resulted in some karst areas of the United States being designated as national or state parks and commercial caverns. Karst aquifers and landscapes that form in tropical areas, such as the north coast of Puerto Rico, differ greatly from karst areas in more arid climates, such as central Texas or western South Dakota. Many of these public and private lands contain unique flora and fauna associated with the hydrologic systems in these karst areas. As a result, multiple Federal, State, and local agencies have an interest in the study of karst terrains. Carbonate sediments and rocks (limestone and dolomite) are composed of greater than 50 percent carbonate minerals and the predominant carbonate mineral is calcium carbonate or limestone (CaCO3). Unlike terrigenous clastic sedimentation, the depositional processes that produce carbonate rocks are complex, involving both biological and physical processes. These depositional processes impact greatly the development of permeability of the sediments. Carbonate minerals readily dissolve or precipitate depending on the chemistry of the water flowing through the rock, thus the study of both marine and meteoric diagenesis of carbonate sediments is multidisciplinary. Even with a better understanding of the depositional environment and subsequent diagenesis, the dual porosity nature of karst aquifers presents challenges to scientists attempting to study ground-water flow and contaminant transport. Many of the major springs and aquifers in the United States are developed in carbonate rocks and karst areas. These aquifers and the springs that discharge from them, serve as major water-supply sources and as unique biological habitats. Commonly, there is competition for the water resources of karst aquifers, and urban development in karst areas can impact the ecosystem and water quality of these aquifers. The concept for developing a Karst Interest Group evolved from the November 1999 National Ground-Water Meeting of the U.S. Geological Survey (USGS), Water Resources Division. As a result, the Karst Interest Group was formed in 2000. The Karst Interest Group is a loose-knit grass-roots organization of USGS employees devoted to fostering better communication among scientists working on, or interested in, karst hydrology studies. The mission of the Karst Interest Group is to encourage and support interdisciplinary collaboration and technology transfer among USGS scientists working in karst areas. Additionally, the Karst Interest Group encourages cooperative studies between the different disciplines of the USGS and other Department of Interior agencies and university researchers or research institutes. The first Karst Interest Group workshop was held in St. Petersburg, Florida, February 13-16, 2001, in the vicinity of karst features of the Floridan aquifer system. The proceedings of that first meeting, Water-Resources Investigations Report 01-4011 are available online at: http://water.usgs.gov/ogw/karst/ The second Karst Interest Group workshop was held August 20-22, 2002, in Shepherdstown, West Virginia, in close proximity to the carbonate aquifers of the northern Shenandoah Valley. The proceedings of the second workshop were published in Water-Resources Investigations Report 02-4174, which is available online at the previously mentioned website. The third workshop of the Karst Interest Group was held September, 12-15, 2005, in Rapid City, South Dakota, which is in close proximity to karst features

2014-12-01

Florida International University (FIU), the State University of Florida in Miami is a large enrollment, federally recognized Minority Serving Institution with over 70% of the undergraduate population coming from groups underrepresented in the geoscience workforce. Recruiting local students into the geosciences is challenging because geology is not well integrated into the local school curriculum, the geology is poorly exposed in the low-relief south Florida region and many first generation college students are reluctant to enter unfamiliar fields. We describe and present preliminary findings from Growing Community Roots for the Geosciences in Miami, FL, a 2-year, NSF funded project run by the Department of Earth and Environment at FIU which aims to inform students enrolled in the local middle and high schools to educational and career opportunities in the geosciences. The project takes a multi-faceted approach which includes direct outreach through social media platforms and school visits, a 1-week workshop for middle school teachers and a 2-week summer camp aimed at high school students. An outreach team of undergraduate geoscience majors were recruited to build and maintain informational resources on Facebook, Instagram, Twitter and Google Plus and to accompany FIU faculty on visits to local middle schools and high schools. Both the teacher workshop and the summer camp included lectures on geoscience careers, fundamental concepts of solid earth and atmospheric science, hands on exercises with earth materials, fossils and microscopy, exercises with Google Earth imagery and GIS, and field trips to local geological sites and government facilities. Participants were surveyed at the beginning of the programs on their general educational background in math and science and their general attitudes of and interest in geoscience careers. Post program surveys showed significant increases in the comfort of teaching topics in geoscience among teachers and an increased interest in majoring in geoscience among students. On the final day of the programs, participants were queried on better ways of interesting high school to major in geoscience. Suggestions included visits by faculty and college students to high schools and using social media to promote events and activities.

A Survey of the Medical Needs of a Group of Small Factories*

PubMed Central

Lee, W. R.

1962-01-01

The present interest in medical services for small factories is matched by the limited objective information which is available on the demand for and needs of such services. As a teaching project, a survey was made of factories with between 30 and 200 employees on an estate in the North West where there was no organized medical service. Unfortunately, time allowed only 22 factories to be visited. The findings, therefore, are regarded as indicative rather than conclusive, but this does not detract from their interest. Factories were visited by two or three postgraduate students who completed a questionnaire designed to standardize their findings. The questionnaire is included as an appendix to this paper. Regarding the demand for medical services, four of the 22 factories were subsidiaries of larger organizations and had part-time medical advice, 14 expressed no interest even if this would have involved no financial commitment, and the remaining four were interested for differing reasons. The needs of the factories in this context were found to be, first, advice and perhaps better supervision of non-mechanical hazards and, secondly, supervision of the first aid arrangements. From the ambulance journey records of the local authority there appeared to be no great demand for local casualty facilities. To meet these needs it is suggested that the functions of the appointed factory doctor might be modified to include wider supervision of non-mechanical hazards and supervision of first aid arrangements. It is also suggested that the National Health Service should form the basis for dealing with those cases requiring more than first aid. PMID:14463582

The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane) from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups) with no treatment (control group) or opioid administration (opioid group) where the outcomes of interest were postoperative pain intensity, rescue analgesic consumption, or adverse effects (sedation, nausea and vomiting, bad dream, worsening sleep pattern, and hallucination) 0-24 hours after leaving the operation room were included in the analysis. The pain score reported by the physician during first 4 hours and need for analgesics during 24 hours postoperatively was significantly decreased in the ketamine group versus control group and was similar with the opioid group. In addition, there was no significant difference between ketamine and control groups for adverse effects during 24 hours postoperatively. In the subgroup analyses (systemic and local administration) regarding pain related measurements, peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity and need for analgesics. Preoperative administration of ketamine systemically or locally could provide pain relief without side-effects in children undergoing tonsillectomy. However, considering the insufficient evaluation of efficacy of ketamine according to the administration methods and high heterogeneity in some parameters, further clinical trials with robust research methodology should be conducted to confirm the results of this study.

The paper highlights key trajectories and outcomes of the recent policy developments toward integrated health care delivery systems in Quebec and Ontario in the primary care sector and in the development of regional networks of health and social services. It particularly explores how policy legacies, interests and cultures may be mitigated to develop and sustain different models of integrated health care that are pertinent to the local contexts. In Quebec, three decades of iterative developments in health and social services evolved in 2005 into integrated centres for health and social services at the local levels (CSSSs). Four integrated university-based health care networks provide ultra-specialised services. Family Medicine Groups and network clinics are designed to enhance access and continuity of care. Ontario's Family Health Teams (2004) constitute an innovative public funding for private delivery model that is set up to enhance the capacity of primary care and to facilitate patient-based care. Ontario's Local Health Integration Networks (LHINs) with autonomous boards of provider organisations are intended to coordinate and integrate care. Integration strategies in Quebec and Ontario yield clinical autonomy and power to physicians while simultaneously making them key partners in change. Contextual factors combined with increased and varied forms of physician remunerations and incentives mitigated some of the challenges from policy legacies, interests and cultures. Virtual partnerships and accountability agreements between providers promise positive but gradual movement toward integrated health service systems.

Luminescent Rhenium(I) and Iridium(III) Polypyridine Complexes as Biological Probes, Imaging Reagents, and Photocytotoxic Agents.

Although the interactions of transition metal complexes with biological molecules have been extensively studied, the use of luminescent transition metal complexes as intracellular sensors and bioimaging reagents has not been a focus of research until recently. The main advantages of luminescent transition metal complexes are their high photostability, long-lived phosphorescence that allows time-resolved detection, and large Stokes shifts that can minimize the possible self-quenching effect. Also, by the use of transition metal complexes, the degree of cellular uptake can be readily determined using inductively coupled plasma mass spectrometry. For more than a decade, we have been interested in the development of luminescent transition metal complexes as covalent labels and noncovalent probes for biological molecules. We argue that many transition metal polypyridine complexes display triplet charge transfer ((3)CT) emission that is highly sensitive to the local environment of the complexes. Hence, the biological labeling and binding interactions can be readily reflected by changes in the photophysical properties of the complexes. In this laboratory, we have modified luminescent tricarbonylrhenium(I) and bis-cyclometalated iridium(III) polypyridine complexes of general formula [Re(bpy-R(1))(CO)3(py-R(2))](+) and [Ir(ppy-R(3))2(bpy-R(4))](+), respectively, with reactive functional groups and used them to label the amine and sulfhydryl groups of biomolecules such as oligonucleotides, amino acids, peptides, and proteins. Additionally, using a range of biological substrates such as biotin, estradiol, and indole, we have designed luminescent rhenium(I) and iridium(III) polypyridine complexes as noncovalent probes for biological receptors. The interesting results generated from these studies have prompted us to investigate the possible applications of luminescent transition metal complexes in intracellular systems. Thus, in the past few years, we have developed an interest in the cytotoxic activity, cellular uptake, and bioimaging applications of these complexes. Additionally, we and other research groups have demonstrated that many transition metal complexes have facile cellular uptake and organelle-localization properties and that their cytotoxic activity can be readily controlled. For example, complexes that can target the nucleus, nucleolus, mitochondria, lysosomes, endoplasmic reticulum, and Golgi apparatus have been identified. We anticipate that this selective localization property can be utilized in the development of intracellular sensors and bioimaging reagents. Thus, we have functionalized luminescent rhenium(I) and iridium(III) polypyridine complexes with various pendants, including molecule-binding moieties, sugar molecules, bioorthogonal functional groups, and polymeric chains such as poly(ethylene glycol) and polyethylenimine, and examined their potentials as biological reagents. This Account describes our design of luminescent rhenium(I) and iridium(III) polypyridine complexes and explains how they can serve as a new generation of biological reagents for diagnostic and therapeutic applications.

In Aotearoa New Zealand, Māori aspirations around land and water conflict with settler interests. As indigenous people, Māori struggle to enact agency over resources, despite Treaty (Treaty of Waitangi/Te Tiriti o Waitangi is an 1840 agreement between Maori and the crown) settlement processes returning some lands. Returns are complex since changes wrought by dispossession may be extreme, requiring multiple stakeholder engagements. Tāngonge, a heavily modified wetland, in northern Aotearoa New Zealand has been the subject of iwi (tribe or tribes) claims since the 1890s. Reparation processes have returned significant areas surrounding Tāngonge to key iwi, Te Rarawa and Ngāi Takoto, who formed the Tāngonge Restoration Group to plan management and restoration. The vision of the iwi is to restore Tangonge as a wetland to rekindle usage by manawhenua (people with demonstrated authority and tribal links to the area in question) and local communities. However, perceived Māori privilege, distrust in Māori praxis and fear of alienation of stakeholders mean the situation presents challenges as well as opportunities. Understanding that various parties view knowledge in particular ways, the Restoration Group sought to juxtapose technical data and manawhenua knowledge about Tāngonge. Hydrology findings and local aspirations were aligned to produce ideas for actions that encompassed the broad concerns. This integration of knowledge provides strategic steps for working with administrative authorities who have historical and ongoing interests.

Five radio shows; a full-page color spread in the campus newspaper; YouTube videos; an interactive activity at the local children's museum; a star party for a dorm; children's books; an outing with Boy Scouts. This is just a sampling of group projects planned and executed in a single semester by students in an introductory course for non-science majors. Everyone in the class joins a group self-organized around common interests to produce a product or activity that communicates some aspect of astronomy to a segment of the general population. These projects give the students a creative outlet to merge some of their outside interests with the course material, a practical exposure to scientific communication, an opportunity for peer instruction including peer evaluation, and a chance to hone their skills in managing group dynamics. The semester long effort begins with everyone in the class submitting individual ideas for subjects and presentation methods. After these ideas are categorized, students begin organizing the groups on a web discussion board. They articulate learning goals for the intended audience and describe how they plan to evaluate the success of the project and the attainment of these goals. The group members seek outside advice from people in other groups during one week of the course discussion section. They submit a progress report and then a first draft, the latter also sent to a different group for review. After feedback from the instructor and a week of the teaching assistant's (TA's) office hours devoted to scheduled meetings with each group, the students draft the final versions or make presentations near the end of the semester.

The Star Cluster System in the Local Group Starburst Galaxy IC 10

We present a survey of star clusters in the halo of IC 10, a starburst galaxy in the Local Group, based on Subaru R-band images and NOAO Local Group Survey UBVRI images. We find five new star clusters. All of these star clusters are located far from the center of IC 10, while previously known star clusters are mostly located in the main body. Interestingly, the distribution of these star clusters shows an asymmetrical structure elongated along the east and southwest directions. We derive UBVRI photometry of 66 star clusters, including these new star clusters, as well as previously known star clusters. Ages of the star clusters are estimated from a comparison of their UBVRI spectral energy distribution with the simple stellar population models. We find that the star clusters in the halo are all older than 1 Gyr, while those in the main body have various ages, from very young (several Myr) to old (\\gt 1 Gyr). The young clusters (\\lt 10 Myr) are mostly located in the Hα emission regions and are concentrated on a small region at 2\\prime\\prime in the southeast direction from the galaxy center, while the old clusters are distributed in a wider area than the disk. Intermediate-age clusters (∼100 Myr) are found in two groups. One is close to the location of the young clusters and the other is at ∼ 4\\prime\\prime from the location of the young clusters. The latter may be related to past mergers or tidal interaction.

"I Think I Can . . . Maybe I Can . . . I Can't": Social Work Women and Local Elected Office.

Meehan, Patrick

2018-04-01

If women are more interested in running for office, it should be observable in MSW students. Not only are the majority of students women, but they have experienced a dramatic change in political fortunes within the last year. However, the 2016 election may be leading women to doubt their qualifications to run. Using survey data from 545 MSW students and 200 law students, this study considers how interested women are in running for office and what barriers they perceive to doing so. Results suggest that women in MSW programs were significantly more interested in running for local office (city council, school board, county commission) than women in law school. At the same time, women in MSW programs were significantly more likely to doubt their qualifications to run for local office, which significantly decreased their interest in running. Content analysis revealed that women felt this way because they did not believe they had the knowledge and experience to run for local office. These results suggest that field placements in political offices might be a way to provide women in MSW programs with knowledge and experience that increases their sense of qualification to run for local office.

'Those were taken away and given money': power and reward expectations' influence in the selection of village health teams in rural Uganda.

PubMed

Turinawe, Emmanueil B

2016-01-01

With the renewed call for community participation in health interventions after the Alma Ata Declaration, interest has been raised in volunteer community health workers (CHWs) acting as representatives of local communities. The present study interrogates the dynamic interface between local communities and the government in the selection of CHW volunteers in a rural community. Data were collected through participant observation of community events, 35 in-depth interviews, 20 focus groups and 15 informal conversations. A review of documents about Luwero district was also an important source of data. Ambiguous national guidelines and poor supervision of the selection process enabled the powerful community leaders to influence the selection of village health teams (VHTs). Intended to achieve community involvement, the selection process produced a disconnect in the local community where many members saw the selected VHTs as having been 'taken away'. Community involvement in the selection of VHTs took a form that, instead of empowering the local community, reinforced the responsibility of those in power and thus maintained the asymmetrical status quo.

The development of new materials often dependents on the theoretical foundations which study the microscopic matter, i.e., the way atoms interact and create distinct configurations. Among the interesting materials, those with partially filled d or f orbitals immersed in nonmagnetic metals have been described by the Anderson model, which takes into account Coulomb correlation (U) when a local level (energy Ed) is doubled occupied, and an electronic hybridization between local levels and conduction band states. In addition, here we include a correlated hybridization term, which depends on the local-level occupation number involved. This term breaks particle-hole symmetry (even when U + 2Ed = 0), enhances charge fluctuations on local levels and as a consequence strongly modifies the crossover between the Hamiltonian fixed-points, even suppressing one or other. We exemplify these behaviors showing data obtained from the Numerical Renormalization Group (NRG) computation for the impurity temperature-dependent specific heat, entropy and magnetic susceptibility. The interleaving procedure is used to recover the continuum spectrum after the NRG-logarithmic discretization of the conduction band. Fundação de Amparo à Pesquisa do Estado de São Paulo - FAPESP.

Primary care perceptions of neurology and neurology services.

Neurophobia (fear of neural sciences) and evaluation of independent sector contracts in neurology have seldom been examined among general practitioners (GPs). A questionnaire determined GPs' perceptions of neurology compared with other medical specialties. GP experiences of neurology services with independent sector companies and the local National Health Service (NHS) were compared. Areas of potential improvement in NHS neurology services were recorded from thematic analyses. Among 76 GPs neurology was perceived to be as interesting as other medical specialties. GPs reported less knowledge, more difficulty and less confidence in neurology compared with other medical specialties. There was a preference for a local NHS neurology service (p<0.001), which was easier to contact (p<0.001) and provided better follow-up. GPs reported that local neurology services provided better patient satisfaction. GPs prefer local NHS neurology services to independent sector contracts. GPs' evaluations should inform commissioning of neurology services. Combating neurophobia should be an integral part of responsive commissioning. Published by the BMJ Publishing Group Limited.

Extensive sequence-influenced DNA methylation polymorphism in the human genome

PubMed Central

2010-01-01

Background Epigenetic polymorphisms are a potential source of human diversity, but their frequency and relationship to genetic polymorphisms are unclear. DNA methylation, an epigenetic mark that is a covalent modification of the DNA itself, plays an important role in the regulation of gene expression. Most studies of DNA methylation in mammalian cells have focused on CpG methylation present in CpG islands (areas of concentrated CpGs often found near promoters), but there are also interesting patterns of CpG methylation found outside of CpG islands. Results We compared DNA methylation patterns on both alleles between many pairs (and larger groups) of related and unrelated individuals. Direct observation and simulation experiments revealed that around 10% of common single nucleotide polymorphisms (SNPs) reside in regions with differences in the propensity for local DNA methylation between the two alleles. We further showed that for the most common form of SNP, a polymorphism at a CpG dinucleotide, the presence of the CpG at the SNP positively affected local DNA methylation in cis. Conclusions Taken together with the known effect of DNA methylation on mutation rate, our results suggest an interesting interdependence between genetics and epigenetics underlying diversity in the human genome.

We present a family of scale-invariant local shape features formed by chains of k connected, roughly straight contour segments (kAS), and their use for object class detection. kAS are able to cleanly encode pure fragments of an object boundary, without including nearby clutter. Moreover, they offer an attractive compromise between information content and repeatability, and encompass a wide variety of local shape structures. We also define a translation and scale invariant descriptor encoding the geometric configuration of the segments within a kAS, making kAS easy to reuse in other frameworks, for example as a replacement or addition to interest points. Software for detecting and describing kAS is released on lear.inrialpes.fr/software. We demonstrate the high performance of kAS within a simple but powerful sliding-window object detection scheme. Through extensive evaluations, involving eight diverse object classes and more than 1400 images, we 1) study the evolution of performance as the degree of feature complexity k varies and determine the best degree; 2) show that kAS substantially outperform interest points for detecting shape-based classes; 3) compare our object detector to the recent, state-of-the-art system by Dalal and Triggs [4].

Nonlocal quantum effective actions in Weyl-Flat spacetimes

2018-06-01

Virtual massless particles in quantum loops lead to nonlocal effects which can have interesting consequences, for example, for primordial magnetogenesis in cosmology or for computing finite N corrections in holography. We describe how the quantum effective actions summarizing these effects can be computed efficiently for Weyl-flat metrics by integrating the Weyl anomaly or, equivalently, the local renormalization group equation. This method relies only on the local Schwinger-DeWitt expansion of the heat kernel and allows for a re-summation of the anomalous leading large logarithms of the scale factor, log a( x), in situations where the Weyl factor changes by several e-foldings. As an illustration, we obtain the quantum effective action for the Yang-Mills field coupled to massless matter, and the self-interacting massless scalar field. Our action reduces to the nonlocal action obtained using the Barvinsky-Vilkovisky covariant perturbation theory in the regime R 2 ≪ ∇2 R for a typical curvature scale R, but has a greater range of validity effectively re-summing the covariant perturbation theory to all orders in curvatures. In particular, it is applicable also in the opposite regime R 2 ≫ ∇2 R, which is often of interest in cosmology.

Growing Community Roots for the Geosciences is a 2-year pilot recruitment project run by the Department of Earth and Environment at Florida International University (FIU) and funded by the NSF OEDG (Opportunities for Enhancing Diversity in the Geosciences) program. FIU, the State University of Florida in Miami is a federally recognized Minority Serving Institution with over 70% of the undergraduate population coming from groups underrepresented in the geoscience workforce. The goal of this project is to inform students enrolled in the local middle and high schools to career opportunities in the geosciences and to promote pathways for underrepresented groups to university geoscience degree programs. The first year's program included a 1-week workshop for middle school teachers and a 2-week summer camp aimed at high school students in the public school system. The teacher workshop was attended by 20 teachers who taught comprehensive and physical science in grades 6-8. It included lectures on geoscience careers, fundamental concepts of solid earth and atmospheric science, hands on exercises with earth materials, fossils and microscopy, interpretation of landform with Google Earth imagery, and a field trip to a local working limestone quarry. On the first day of the workshop, participants were surveyed on their general educational background in science and their familiarity and comfort with teaching basic geoscience concepts. On the final day, the teachers participated in a group discussion where we discussed how to make geoscience topics and careers more visible in the school curriculum. The 2-week summer camp was attended by 21 students entering grades 9-12. The program included hands on exercises on geoscience and GIS concepts, field trips to local barrier islands, the Everglades, a limestone quarry and a waste to energy facility, and tours of the NOAA National Hurricane Center and the FIU SEM lab. Participants were surveyed on their general educational background in math and science as well as their general interest in geoscience careers. In separate focus groups, participants were queried on better ways of interesting high school students in geoscience majors. Suggestions included visits by faculty and college students to high schools and using social media promote events and activities

Mass fatality incidents can overwhelm local, state and national resources quickly. Dental hygienists are widely distributed and have the potential to increase response teams' capacity. However, appropriate training is required. The literature is void of addressing this type of training for dental hygienists and scant in dentistry. Hence, the purpose of this study was to assess one facet of such training: Whether the use of multimedia is likely to enhance educational outcomes related to mass fatality training. A randomized, double-blind, pre- and post-test design was used to evaluate the effectiveness of comparable educational modules for 2 groups: a control group (n=19) that received low media training and a treatment group (n=20) that received multimedia training. Participants were second-year, baccalaureate dental hygiene students. Study instruments included a multiple-choice examination, a clinical competency-based radiology lab scored via a standardized rubric, and an assessment of interest in mass fatality education as a specialty. ANOVA was used to analyze results. Participants' pre- and post-test scores and clinical competency-based radiology lab scores increased following both educational approaches. Interest in mass fatality training also increased significantly for all participants (p=0.45). There was no significant difference in pre- and post-test multiple choice scores (p=0.6455), interest (p=0.9133) or overall competency-based radiology lab scores (p=0.997) between groups. Various educational technique may be effective for mass fatality training. However, mass fatality training that incorporates multimedia is an appropriate avenue for training instruction. Continued research about multimedia's role in this specialty area is encouraged. Copyright © 2015 The American Dental Hygienists’ Association.

Differences in change blindness to real-life scenes in adults with autism spectrum conditions.

People often fail to detect large changes to visual scenes following a brief interruption, an effect known as 'change blindness'. People with autism spectrum conditions (ASC) have superior attention to detail and better discrimination of targets, and often notice small details that are missed by others. Together these predict people with autism should show enhanced perception of changes in simple change detection paradigms, including reduced change blindness. However, change blindness studies to date have reported mixed results in ASC, which have sometimes included no differences to controls or even enhanced change blindness. Attenuated change blindness has only been reported to date in ASC in children and adolescents, with no study reporting reduced change blindness in adults with ASC. The present study used a change blindness flicker task to investigate the detection of changes in images of everyday life in adults with ASC (n = 22) and controls (n = 22) using a simple change detection task design and full range of original scenes as stimuli. Results showed the adults with ASC had reduced change blindness compared to adult controls for changes to items of marginal interest in scenes, with no group difference for changes to items of central interest. There were no group differences in overall response latencies to correctly detect changes nor in the overall number of missed detections in the experiment. However, the ASC group showed greater missed changes for marginal interest changes of location, showing some evidence of greater change blindness as well. These findings show both reduced change blindness to marginal interest changes in ASC, based on response latencies, as well as greater change blindness to changes of location of marginal interest items, based on detection rates. The findings of reduced change blindness are consistent with clinical reports that people with ASC often notice small changes to less salient items within their environment, and are in-line with theories of enhanced local processing and greater attention to detail in ASC. The findings of lower detection rates for one of the marginal interest conditions may be related to problems in shifting attention or an overly focused attention spotlight.

Many countries have demonstrated interest in expanding their medical tourism sectors because of its potential economic and health system benefits. However, medical tourism poses challenges to the equitable distribution of health resources between international and local patients and private and public medical facilities. Currently, very little is known about how medical tourism is perceived among front line workers and users of health systems in medical tourism 'destinations'. Barbados is one such country currently seeking to expand its medical tourism sector. Barbadian nurses and health care users were consulted about the challenges and benefits posed by ongoing medical tourism development there. Focus groups were held with two stakeholder groups in May, 2013. Nine (n = 9) citizens who use the public health system participated in the first focus group and seven (n = 7) nurses participated in the second. Each focus group ran for 1.5 hours and was digitally recorded. Following transcription, thematic analysis of the digitally coded focus group data was conducted to identify cross-cutting themes and issues. Three core concerns regarding medical tourism's health equity impacts were raised; its potential to 1) incentivize migration of health workers from public to private facilities, 2) burden Barbados' lone tertiary health care centre, and 3) produce different tiers of quality of care within the same health system. These concerns were informed and tempered by the existing a) health system structure that incorporates both universal public healthcare and a significant private medical sector, b) international mobility among patients and health workers, and c) Barbados' large recreational tourism sector, which served as the main reference in discussions about medical tourism's impacts. Incorporating these concerns and contextual influences, participants' shared their expectations of how medical tourism should locally develop and operate. By engaging with local health workers and users, we begin to unpack how potential health equity impacts of medical tourism in an emerging destination are understood by local stakeholders who are not directing sector development. This further outlines how these groups employ knowledge from their home context to ground and reconcile their hopes and concerns for the impacts posed by medical tourism.

As potential candidates for deep-UV nonlinear optical (NLO) crystals, borosilicates and borogermanates, which contain NLO-active groups such as B-O, Si-O, and Ge-O groups, have fascinated many material scientists' research enthusiasm. In this paper, the electronic structures and optical properties of two isostructural noncentrosymmetric crystals LaBRO{sub 5} (R = Si and Ge) have been studied by the first-principles method. Combined with the analyses of the SHG-density and the localized electron-density difference, contributions of the constituent tetrahedra to the total NLO responses are investigated. Eventually, BO{sub 4} and GeO{sub 4} groups give nearly equal contributions to the SHG effect of LaBGeO{sub 5}, but formore » LaBSiO{sub 5}, SiO{sub 4} groups express stronger SHG response than that of BO{sub 4}. Such interesting conclusion is consistent with the distortion index analyses and dipole moment.« less

'Between a rock and a hard place': applied anthropology and AIDS research on a commercial farm in Zambia.

Bond, V

1997-01-01

Fieldwork on a commercial farm in southern Zambia, which was aimed at designing an HIV prevention program for farm workers, gradually exposed the nature of sexual liaisons between young girls, coming to work on the farm from the surrounding villages, and older migrant men workers. Before completing fieldwork, the anthropologist voiced her concern about the implications of these liaisons for the spread of STDs and HIV with the local rural community, farm management and farm workers. The immediate outcome of her intercessions was the decision by management to sack under-age workers. Although some members of the local community, including local research assistants, and some managers and workers welcomed this decision, others were angered by it. Caught between interest groups and conflicting guidelines, the anthropologist, it is argued, was in a no-win situation, 'between a rock and a hard place'. The paper proposes that the application of anthropological ethics in AIDS research needs some re-evaluation.

Recent Local and State Action in Arizona to Maintain Sky Quality

NASA Astrophysics Data System (ADS)

Hall, Jeffrey C.; Shankland, P. D.; Green, R. F.; Jannuzi, B.

2014-01-01

The large number of observatories in Arizona has led to the development of a number of lighting control ordinances around the state, some quite strict. Several factors are now contributing to an increased need for active effort at the local, County, and State levels in maintaining the quality of these codes; these factors include an expansion of competing interests in the state, the increasing use of LED lighting, and the potential for major new investments through projects such as the Cherenkov Telescope Array (CTA) and enhancements to the Navy Precision Optical Interferometer. I will review recent strategies Arizona's observatories have used to effect maintenance of ordinances and preserve sky quality; cases include (1) a statewide effort in 2012 to curb a proliferation of electronic billboards and (2) engagement of a broad group of local, County, and State officials, as well as individuals from the private sector, in support of projects like CTA, including awareness of and support for dark-sky preservation.

Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF.

Background and objectives The goal of this meta-analysis study was to perform a systematic review of the literature on the effects of ketamine on postoperative pain following tonsillectomy and adverse effects in children. Subjects and Methods Two authors independently searched three databases (MEDLINE, SCOPUS, Cochrane) from their inception of article collection to February 2014. Studies that compared preoperative ketamine administration (ketamine groups) with no treatment (control group) or opioid administration (opioid group) where the outcomes of interest were postoperative pain intensity, rescue analgesic consumption, or adverse effects (sedation, nausea and vomiting, bad dream, worsening sleep pattern, and hallucination) 0–24 hours after leaving the operation room were included in the analysis. Results The pain score reported by the physician during first 4 hours and need for analgesics during 24 hours postoperatively was significantly decreased in the ketamine group versus control group and was similar with the opioid group. In addition, there was no significant difference between ketamine and control groups for adverse effects during 24 hours postoperatively. In the subgroup analyses (systemic and local administration) regarding pain related measurements, peritonsillar infiltration of ketamine was more effective in reducing the postoperative pain severity and need for analgesics. Conclusion Preoperative administration of ketamine systemically or locally could provide pain relief without side-effects in children undergoing tonsillectomy. However, considering the insufficient evaluation of efficacy of ketamine according to the administration methods and high heterogeneity in some parameters, further clinical trials with robust research methodology should be conducted to confirm the results of this study.

Mitochondrial DNA (mtDNA) analysis has proved useful in studies of recent human evolution and the genetic affinities of human groups of different geographical regions. As part of an extensive survey of mtDNA diversity in present-day Pacific populations, we obtained sequence information of the hypervariable mtDNA control region of 452 individuals from various localities in the western Pacific. The mtDNA types fell into three major groups which reflect the settlement history of the area. Interestingly, we detected an extremely rare point mutation at high frequency in the small island of Nguna in the Melanesian archipelago of Vanuatu. Phylogenetic analysis of the mtDNA data indicated that the mutation was present in individuals of separate mtDNA lineages. We propose that the multiple occurrence of a rare mutation event in one isolated locality is highly improbable, and that recombination between different mtDNA types is a more likely explanation for our observation. If correct, this conclusion has important implications for the use of mtDNA in phylogenetic and evolutionary studies. PMID:10189712

The purpose was to conduct focus groups with Hispanic employees to obtain input into adaptation of previous DSME interventions for use as a workplace diabetes prevention program. From a list of interested Hispanic employees who attended a local health fair (n = 68), 36 were randomly selected to participate in focus groups held during supper mealtime breaks. An experienced bilingual moderator directed the sessions, using interview guidelines developed by the research team. Participants' ages ranged from 22 to 65 years (mean = 50.4, n = 36, SD = 10.7), 7 males and 29 females attended, and 53% had type 2 diabetes mellitus (T2DM). Employees expressed a keen interest in diabetes classes and recommended a focus on preparing healthier Hispanic foods. Primary barriers to promoting healthier lifestyles were work schedules; many employees worked 2 part-time or full-time jobs. Administrators and direct supervisors of the employees were highly supportive of a workplace diabetes prevention program. The consistent message was that a workplace program would be the ideal solution for Hispanic employees to learn about diabetes and healthy behaviors, given their busy schedules, family responsibilities, and limited resources. If found to be effective, such a workplace program would be generalizable to other service employees who have disproportionate diabetes rates. © 2015 The Author(s).

Enacting localist health policy in the English NHS: the 'governing assemblage' of Clinical Commissioning Groups.

PubMed

Hammond, Jonathan; Coleman, Anna; Checkland, Kath

2018-01-01

Objectives The Health and Social Care Act 2012 introduced Clinical Commissioning Groups to take responsibility for commissioning (i.e. planning and purchasing) the majority of services for local populations in the English NHS. Constituted as 'membership organizations', with membership compulsory for all GP practices, Clinical Commissioning Groups are overseen by, and are accountable to, a new arm's-length body, NHS England. This paper critically engages with the content and policy narrative of the 2012 Act and explores this in relation to the reality of local policy enactment. Methods Set against a careful review of the 2012 Act, a case study of a nascent Clinical Commissioning Groups was conducted. The research included observations of Clinical Commissioning Group meetings and events (87 h), and in-depth interviews (16) with clinical commissioners, GPs, and managers. Results The 2012 Act was presented as part of a broader government agenda of decentralization and localism. Clinical Commissioning Group membership organizations were framed as a means of better meeting the needs and preferences of local patients and realizing a desirable increase in localism. The policy delineated the 'governing body' and 'the membership', with the former elected from/by the latter to oversee the organization. 'The membership' was duty bound to be 'good', engaged members and to represent their patients' interests. Fieldwork with Notchcroft Clinical Commissioning Group revealed that Clinical Commissioning Groups' statutory duty to NHS England to 'ensure the continuous improvement' of GP practice members involved performance scrutiny of GP practices. These governance processes were carried out by a varied cast of individuals, many of whom did not fit into the binary categorization of membership and governing body constructed in the policy. A concept, the governing assemblage, was developed to describe the dynamic cast of people involved in shaping the work and direction of the Clinical Commissioning Group, many of whom were unelected and of uncertain status. This was of particular significance in Notchcroft Clinical Commissioning Group because the organization explicitly pursued a governance system based on developing positions of consensus. The governing assemblage concept is valuable in articulating the actual practices of Clinical Commissioning Group governance, how these relate to the normative content of the 2012 Act, and the tensions that emerge. Conclusions The governing assemblage concept provided clarity in discussion of the dynamics of organizational governance in Notchcroft Clinical Commissioning Group, which did not follow the simple template articulated in the 2012 Act. The concept merits application in the study of other Clinical Commissioning Groups and may prove valuable in illuminating governance processes within a range of other health care organizations in different contexts. The governing assemblage holds promise for the analysis of ongoing changes to NHS organization, as well as international health care organizations such as accountable care organizations in the US.

Will dengue vaccines be used in the public sector and if so, how? Findings from an 8-country survey of policymakers and opinion leaders.

2013-01-01

A face-to-face survey of 158 policymakers and other influential professionals was conducted in eight dengue-endemic countries in Asia (India, Sri Lanka, Thailand, Vietnam) and Latin America (Brazil, Colombia, Mexico, Nicaragua) to provide an indication of the potential demand for dengue vaccination in endemic countries, and to anticipate their research and other requirements in order to make decisions about the introduction of dengue vaccines. The study took place in anticipation of the licensure of the first dengue vaccine in the next several years. Semi-structured interviews were conducted on an individual or small group basis with government health officials, research scientists, medical association officers, vaccine producers, local-level health authorities, and others considered to have a role in influencing decisions about dengue control and vaccines. Most informants across countries considered dengue a priority disease and expressed interest in the public sector use of dengue vaccines, with a major driver being the political pressure from the public and the medical community to control the disease. There was interest in a vaccine that protects children as young as possible and that can fit into existing childhood immunization schedules. Dengue vaccination in most countries surveyed will likely be targeted to high-risk areas and begin with routine immunization of infants and young children, followed by catch-up campaigns for older age groups, as funding permits. Key data requirements for decision-making were additional local dengue surveillance data, vaccine cost-effectiveness estimates, post-marketing safety surveillance data and, in some countries vaccine safety and immunogenicity data in the local population. The lookout for the public sector use of dengue vaccines in the eight countries appears quite favorable. Major determinants of whether and when countries will introduce dengue vaccines include whether WHO recommends the vaccines, their price, the availability of external financing for lower income countries, and whether they can be incorporated into countries' routine immunization schedules.

Affective neural response to restricted interests in Autism Spectrum Disorders

Background Restricted interests are a class of repetitive behavior in autism spectrum disorders (ASD) whose intensity and narrow focus often contribute to significant interference with daily functioning. While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. Methods We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. Results While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. Conclusions While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals’ own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD. PMID:24117668

Ethical practices in ecological field research differ from those in laboratory research in more than the technical setting and the important distinction between population-level and individual-based concerns. The number of stakeholders affected by the conduct of field research is far larger; private landholders, public water utilities, public land managers, local industries, and communities large and small are only some of those who may be impacted. As research review boards move to establish specific ethical practices for field biologists, the process of identifying appropriate standards will affect the degree to which research will ultimately be disrupted. Standards that lead to research protocols that alienate key interests are not likely to be sustainable. Already, standards that have conflicted with the primary values of a key interest have resulted in disruptions to research and scientific progress. One way to manage this problem of deeply competing interests is to avoid the deepest offenses to any relevant interest group in the design of a proposed study. This is an application of the precautionary principle and is likely to generate a more sustainable balance among competing interests. Unfortunately, this process is also likely to be a never-ending, consensus-seeking process. Fortunately, scientists can have enormous influence on the process if they choose to engage in it early. If scientists use their expertise to function as honest brokers among affected interests, their own interest in scientific research progress is likely to be better met.

Bringing Seismological Research into the School Setting

One of the primary goals of educational seismology programs is to bring inquiry-based research to the middle- and high-school classroom setting. Although it is often stated as a long-term goal of science outreach programs, in practice there are many barriers to research in the school setting, among them increasing emphasis on test-oriented training, decreasing interest and participation in science fairs, limited teacher confidence and experience for mentoring research, insufficient student preparedness for research projects, and the short term of university involvement (typically limited to brief one-day encounters). For the past three+ years we have tried to address these issues through a focused outreach program we have called the PEPP Research Fellows Program. This is treated as an honors program in which high school teachers in our group nominate students with interests in science careers. These students are invited to participate in the program, and those who elect to take part participate in a one-day education and training session in the fall. Rather than leave research projects completely open, we direct the students at toward one of two specific, group-oriented projects (in our case, one focusing on local recordings of mining explosions, and a second on teleseismic body-wave analysis), but we encourage them to act as independent researchers and follow topics of interest. The students then work on seismic data from the local educational network or from the IRIS facilities. Following several months of informal interaction with teachers and students (email, web conferencing, etc.), we bring the students and teachers to our university for a weekend research symposium in the spring. Students present their work in oral or poster form and prizes are given for the best papers. Projects range from highly local projects (records of seismic noise at school X) to larger-scale regional projects (analysis of teleseismic P-wave delays at PEPP network stations) From 20 to 40 students and teachers have participated in the program in the past three years and independent work by students has been outstanding including several students' work that have won awards at regional and national science fairs. The program is feasible because we had a pool of dedicated teachers with experience in using seismographs in schools as a legacy of the Princeton Earth Physics Program (PEPP). It provides a model for focused outreach to top science students to give them an early research experience.

Guided-Inquiry Lessons Raise Scores on the Sixth Grade Georgia Science Test

Page, Purlie M.

At the local level, G Middle School has the highest district-wide percentage of 6th grade science students who are not meeting standards. It is imperative that G middle school take corrective action to reduce the number of students failing to meet state science standards. Dewey's theory of conceptual framework, which involves knowledge constructed on a person's personal experience and mind activity through active forms of learning, guided this study. The goal of the study was to determine whether inquiry-based science modules produce greater 6th grade science achievement, as measured by an equivalent instrument of the science section of the Georgia Criterion-Referenced Competency Test, when compared to traditional instruction among eastern Georgia 6th graders. The sample consisted of 230 students in the nonintervention group and 119 students in the intervention group. All students were from intact classes. At the end of the intervention, an independent t test was conducted to analyze the scores. According to the study t test, (t = 12.33, df = 304.56, p < 0.05), the difference between the means was statistically significant. This project's potential impact on social change includes increasing student motivation towards, comprehension of, and interest in science concepts. At the local level, these inquiry lessons can be shared with science teachers across grade levels and within the district to improve county-wide science scores. An increase in student interest and comprehension of science concepts could ultimately lead to the United States producing more students in the fields of science, technology, engineering, and mathematics (STEM) education.

At first glance this NASA/ESA Hubble Space Telescope image seems to show an array of different cosmic objects, but the speckling of stars shown here actually forms a single body — a nearby dwarf galaxy known as Leo A. Its few million stars are so sparsely distributed that some distant background galaxies are visible through it. Leo A itself is at a distance of about 2.5 million light-years from Earth and a member of the Local Group of galaxies; a group that includes the Milky Way and the well-known Andromeda galaxy. Astronomers study dwarf galaxies because they are very numerous and are  simpler in structure than their giant cousins. However, their small size makes them difficult to study at great distances. As a result, the dwarf galaxies of the Local Group are of particular interest, as they are close enough to study in detail. As it turns out, Leo A is a rather unusual galaxy. It is one of the most isolated galaxies in the Local Group, has no obvious structural features beyond being a roughly spherical mass of stars, and shows no evidence for recent interactions with any of its few neighbours. However, the galaxy’s contents are overwhelmingly dominated by relatively young stars, something that would normally be the result of a recent interaction with another galaxy. Around 90% of the stars in Leo A are less than eight billion years old — young in cosmic terms! This raises a number of intriguing questions about why star formation in Leo A did not take place on the “usual” timescale, but instead waited until it was good and ready.

Prince Albert, Saskatchewan, is experiencing a substance use and addiction crisis with devastating consequences. To engage local stakeholders on substance use and addiction issues, nurse researchers at the University of Saskatchewan, Prince Albert Campus, planned and organized a one-day community engagement and knowledge exchange forum. The forum provided the opportunity for interested community groups, members and individuals to share their experiences and to explore novel ways to prevent and respond to the substance abuse and addiction challenges in the region. Participants included community leaders, people and families living with addiction, service providers, local stakeholders, health professionals, researchers and Indigenous Elders. This paper describes the process and outcomes of this event and describes the role of nurse scholars in leading these efforts. © 2017 Longwoods Publishing.

The current study examined younger and older adults' error detection accuracy, prediction calibration, and postdiction calibration on a proofreading task, to determine if age-related differences would be present in this type of common error detection task. Participants were given text passages, and were first asked to predict the percentage of errors they would detect in the passage. They then read the passage and circled errors (which varied in complexity and locality), and made postdictions regarding their performance, before repeating this with another passage and answering a comprehension test of both passages. There were no age-related differences in error detection accuracy, text comprehension, or metacognitive calibration, though participants in both age groups were overconfident overall in their metacognitive judgments. Both groups gave similar ratings of motivation to complete the task. The older adults rated the passages as more interesting than younger adults did, although this level of interest did not appear to influence error-detection performance. The age equivalence in both proofreading ability and calibration suggests that the ability to proofread text passages and the associated metacognitive monitoring used in judging one's own performance are maintained in aging. These age-related similarities persisted when younger adults completed the proofreading tasks on a computer screen, rather than with paper and pencil. The findings provide novel insights regarding the influence that cognitive aging may have on metacognitive accuracy and text processing in an everyday task.

Cellular structures are of growing interest for industry, and are of particular importance for lightweight applications. In this paper, a special case of metal matrix composite foams (MMCs) is investigated. The investigated foams are composed of austenitic steel exhibiting transformation induced plasticity (TRIP) and magnesia partially stabilized zirconia (Mg-PSZ). Both components exhibit martensitic phase transformation during deformation, thus generating the potential for improved mechanical properties such as strength, ductility, and energy absorption capability. The aim of these investigations was to show that stress-assisted phase transformations within the ceramic reinforcement correspond to strong local deformation, and to determine whether they canmore » trigger martensitic phase transformations in the steel matrix. To this end, in situ interrupted compression experiments were performed in an X-ray computed tomography device (XCT). By using a recently developed registration algorithm, local deformation could be calculated and regions of interest could be defined. Corresponding cross sections were prepared and used to analyze the local phase composition by electron backscatter diffraction (EBSD). The results show a strong correlation between local deformation and phase transformation. - Graphical abstract: Display Omitted - Highlights: • In situ compressive deformation on MMC foams was performed in an XCT. • Local deformation fields and their gradient amplitudes were estimated. • Cross sections were manufactured containing defined regions of interest. • Local EBSD phase analysis was performed. • Local deformation and local phase transformation are correlated.« less

Colonoscopy for colorectal cancer (CRC) has a localization error rate as high as 21 %. Such errors can have substantial clinical consequences, particularly in laparoscopic surgery. The primary objective of this study was to compare accuracy of tumor localization at initial endoscopy performed by either the operating surgeon or non-operating referring endoscopist. All patients who underwent surgical resection for CRC at a large tertiary academic hospital between January 2006 and August 2014 were identified. The exposure of interest was the initial endoscopist: (1) surgeon who also performed the definitive operation (operating surgeon group); and (2) referring gastroenterologist or general surgeon (referring endoscopist group). The outcome measure was localization error, defined as a difference in at least one anatomic segment between initial endoscopy and final operative location. Multivariate logistic regression was used to explore the association between localization error rate and the initial endoscopist. A total of 557 patients were included in the study; 81 patients in the operating surgeon cohort and 476 patients in the referring endoscopist cohort. Initial diagnostic colonoscopy performed by the operating surgeon compared to referring endoscopist demonstrated statistically significant lower intraoperative localization error rate (1.2 vs. 9.0 %, P = 0.016); shorter mean time from endoscopy to surgery (52.3 vs. 76.4 days, P = 0.015); higher tattoo localization rate (32.1 vs. 21.0 %, P = 0.027); and lower preoperative repeat endoscopy rate (8.6 vs. 40.8 %, P < 0.001). Initial endoscopy performed by the operating surgeon was protective against localization error on both univariate analysis, OR 7.94 (95 % CI 1.08-58.52; P = 0.016), and multivariate analysis, OR 7.97 (95 % CI 1.07-59.38; P = 0.043). This study demonstrates that diagnostic colonoscopies performed by an operating surgeon are independently associated with a lower localization error rate. Further research exploring the factors influencing localization accuracy and why operating surgeons have lower error rates relative to non-operating endoscopists is necessary to understand differences in care.

Social accountability has to be configured according to the context in which it operates. This paper aimed to identify local contextual factors in two health zones in the Democratic Republic of the Congo and discuss their possible influences on shaping, implementing and running social accountability initiatives. Data on local socio-cultural characteristics, the governance context, and socio-economic conditions related to social accountability enabling factors were collected in the two health zones using semi-structured interviews and document reviews, and were analyzed using thematic analysis. The contexts of the two health zones were similar and characterized by the existence of several community groups, similarly structured and using similar decision-making processes. They were not involved in the health sector's activities and had no link with the health committee, even though they acknowledged its existence. They were not networked as they focused on their own activities and did not have enough capacity in terms of social mobilization or exerting pressure on public authorities or providers. Women were not perceived as marginalized as they often occupied other positions in the community besides carrying out domestic tasks and participated in community groups. However, they were still subject to the local male dominance culture, which restrains their involvement in decision-making, as they tend to be less educated, unemployed and suffer from a lack of resources or specific skills. The socio-economic context is characterized by subsistence activities and a low employment rate, which limits the community members' incomes and increases their dependence on external support. The governance context was characterized by imperfect implementation of political decentralization. Community groups advocating community rights are identified as "political" and are not welcomed. The community groups seemed not to be interested in the health center's information and had no access to media as it is non-existent. The local contexts in the two health zones seemed not to be supportive of the operation of social accountability initiatives. However, they offer starting points for social accountability initiatives if better use is made of existing contextual factors, for instance by making community groups work together and improving their capacities in terms of knowledge and information.

A demographic survey of unwanted horses in Ireland 2005-2010

PubMed Central

2012-01-01

Background The Irish Horse Industry expanded during the Celtic Tiger boom years, then contracted in the current economic recession. High value horses were traditionally controlled through sale at public auction, private sales and sales to dealers; these are now also being reduced by decreases in production (> 40%), and increases in retirement, re-homing, euthanasia and disposal through Category 2 plants and abattoirs. The absence or banning of horse abattoirs has been shown to have very significant welfare social and economic consequences in the USA. This study described the currently available data on the demographics of unwanted horses in Ireland from 2005 to 2010. Results The majority of horses euthanised by practicing veterinarians are destroyed on medical grounds but the number euthanised at the request of welfare groups and the state, as well as welfare related calls and the number of horses involved in these calls and subsequent visits is increasing reflecting the increasing involvement of the veterinary profession in equine welfare. Welfare groups have limited resources and do not have a tradition of recording data, but they too have reported increasing calls, visits and numbers of horses per visit. Welfare groups provide significant service to equine welfare and the community. Local Authorities report similar trends. Over 300 horses were found dead or required immediate or subsequent euthanasia following welfare group and local authority visits in 2010, which is of national concern. The majority of local authority interfaces with unwanted horses are with urban (60%) rather than rural (40%) horses. Mortality figures are poor indicators of non-fatal neglect. More horses were admitted into the care of local authorities than welfare groups, reflecting significant state and taxpayer investment in the control of low value horses. Category 2 plants and abattoirs represent a significant state investment in licensing and control in the national interest. Abattoirs provide an increasingly important and essential service for the disposal of unwanted horses. Despite the increase in unwanted horses, Ireland is a minority contributor to the EU slaughter total. Conclusions There is a need for annual demographic data compilation and review of the numbers of unwanted horses and ponies within the horse industry to assist policy makers and legislators.

Collective behavior in animal groups: theoretical models and empirical studies

PubMed Central

Giardina, Irene

2008-01-01

Collective phenomena in animal groups have attracted much attention in the last years, becoming one of the hottest topics in ethology. There are various reasons for this. On the one hand, animal grouping provides a paradigmatic example of self-organization, where collective behavior emerges in absence of centralized control. The mechanism of group formation, where local rules for the individuals lead to a coherent global state, is very general and transcends the detailed nature of its components. In this respect, collective animal behavior is a subject of great interdisciplinary interest. On the other hand, there are several important issues related to the biological function of grouping and its evolutionary success. Research in this field boasts a number of theoretical models, but much less empirical results to compare with. For this reason, even if the general mechanisms through which self-organization is achieved are qualitatively well understood, a quantitative test of the models assumptions is still lacking. New analysis on large groups, which require sophisticated technological procedures, can provide the necessary empirical data. PMID:19404431

Building Climate Literacy Through Strategic Partnerships

2012-12-01

One of the challenges of developing climate science literacy is establishing the relevance of both climate science and climate change at a local community level. By developing partnerships with community-based informal science education providers, we are able to build our climate science and climate change content into existing programs. Employing a systems science approach facilitates these partnerships as our systems science program links with a range of topics, demonstrating the multiple connections between climate, our communities and our daily lives. Merging hands on activities, collaborative projects, and new technology, we encourage learning through doing by engaging participants in active exploration of climate science concepts. Many informal education venues operating locally, from large science museums to small grass-roots community groups, provide ongoing opportunities to connect with students. Through our collaborations we have worked with various types and sizes of non-classroom science providers including: the Intrepid Sea, Air and Space Museum "Greater Opportunities Advancing Leadership and Science" camps for high school girls, Hudson River Park Trust 'Science on the River' events, the annual New York City World Science Festival, and the AAUW's annual STEM Super Scholars Workshops among others. This range of venues has enabled us to reach various ages, backgrounds and interests advancing climate literacy in a number of forums. Major outcomes of these efforts are: (1) Building capacity with community groups: Many local organizations running community programs do not have in-house science expertise. Both science educators and local organization benefit from these collaborations. Science educators and scientists provide up to date climate science information to the community groups while these programs establish strong working relationships between our research and the local community. (2) Developing climate science literacy and lifelong learning: We have delivered climate science in a variety of ways, each designed to connect the participants with a fundamental science concept while building excitement for the topic and facilitating learning in a non-traditional setting. Our approaches range from launching teams of young people into experiments exploring glacial physics through free-choice inquiry opportunities, to enlisting undergraduate science students in working with the participants demonstrating glacial motion and measurement through engaging technology such as Kinect Xbox 360 sensors, to short single concept hands-on activities designed to deliver a specific climate 'take home' message. (3) Generating a local connection to climate science and impacts: Working with local informal education groups we connect climate topics to community-based issues and 'hot topics' such as sustainable planning, waterfront erosion, storm surge impacts, and local sea level rise projections. Partnering with community based informal education providers allows us to expand our offerings to reach a wider audience of young people, and to connect more directly with our local community. We are excited by the potential in these partnerships to connect students with climate science and develop not only a climate literate group of young people, but also lifelong science learners.

The Space Science and Applications group (ISR-1) in the Intelligence and Space Research (ISR) division at the Los Alamos National Laboratory lead a number of space science missions for civilian and defense-related programs. In support of these missions the group develops sensors capable of detecting nuclear emissions and measuring radiations in space including γ-ray, X-ray, charged-particle, and neutron detection. The group is involved in a number of stages of the lifetime of these sensors including mission concept and design, simulation and modeling, calibration, and data analysis. These missions support monitoring of the atmosphere and near-Earth space environment for nuclear detonations as well as monitoring of the local space environment including space-weather type events. Expertise in this area has been established over a long history of involvement with cutting-edge projects continuing back to the first space based monitoring mission Project Vela. The group's interests cut across a large range of topics including non-proliferation, space situational awareness, nuclear physics, material science, space physics, astrophysics, and planetary physics.

Comparison of genetic diversity between Canadian adapted genotypes and exotic germplasm of soybean.

PubMed

Iquira, Elmer; Gagnon, Eric; Belzile, François

2010-05-01

Soybean (Glycine max (L.) Merr.) was domesticated in China and the greatest genetic diversity for this species is found in Asia. In contrast, in North America, soybean cultivars trace back to a small number of plant introductions from Asia and genetic diversity is typically quite limited. The purpose of this work was to measure and compare the genetic diversity in two sets of soybean lines. The first set (termed "local") was composed of 100 lines used in a private breeding program in Quebec. The second set (termed "exotic") was composed of 200 lines from elsewhere in the world (but mostly from Asia) and included a few lines of Glycine soja, the wild progenitor of cultivated soybean. Almost all the genotypes belonged to maturity groups between 000 and II. A total of 39 microsatellites (SSRs) were used to genotype the two collections. The number of alleles per locus was almost twice as great in the exotic set compared with the local set. Also, the number of "unique" alleles, i.e., those uniquely present in one set and absent in the other, was almost fivefold greater (191 vs. 37) in a subset of 108 exotic lines with good adaptation than among the local set. A genetic distance matrix, a UPGMA cluster analysis, and a principal coordinate analysis were conducted based on the SSR data. These analyses all indicated that the exotic set was much more diverse and formed a clearly distinct group from the local set. Interestingly, some of the lines showing the best adaptation to local conditions were quite distinctive in terms of their genotype and could potentially contribute useful novel genetic variation within the breeding program.

Conserved Quantities in General Relativity: From the Quasi-Local Level to Spatial Infinity

Chen, Po-Ning; Wang, Mu-Tao; Yau, Shing-Tung

2015-08-01

We define quasi-local conserved quantities in general relativity by using the optimal isometric embedding in Wang and Yau (Commun Math Phys 288(3):919-942, 2009) to transplant Killing fields in the Minkowski spacetime back to the 2-surface of interest in a physical spacetime. To each optimal isometric embedding, a dual element of the Lie algebra of the Lorentz group is assigned. Quasi-local angular momentum and quasi-local center of mass correspond to pairing this element with rotation Killing fields and boost Killing fields, respectively. They obey classical transformation laws under the action of the Poincaré group. We further justify these definitions by considering their limits as the total angular momentum and the total center of mass of an isolated system. These expressions were derived from the Hamilton-Jacobi analysis of the gravitational action and thus satisfy conservation laws. As a result, we obtained an invariant total angular momentum theorem in the Kerr spacetime. For a vacuum asymptotically flat initial data set of order 1, it is shown that the limits are always finite without any extra assumptions. We also study these total conserved quantities on a family of asymptotically flat initial data sets evolving by the vacuum Einstein evolution equation. It is shown that the total angular momentum is conserved under the evolution. For the total center of mass, the classical dynamical formula relating the center of mass, energy, and linear momentum is recovered, in the nonlinear context of initial data sets evolving by the vacuum Einstein evolution equation. The definition of quasi-local angular momentum provides an answer to the second problem in classical general relativity on Penrose's list (Proc R Soc Lond Ser A 381(1780):53-63, 1982).

Originally an educational project at the University of Michigan in the early 1990s, the Weather Underground transformed into the highly successful commercial Internet weather web site, wunderground.com, in 1995. I give an overview of the science communication experiences learned during my 25-year experience with the Weather Underground. Some lessons learned: Find your own unique voice. Be entertaining; don't be such a scientist. Tell stories. Earn people's trust. Use colorful graphs, images that show people, historical events, or scenes of local interest to illustrate your message. Be careful with criticism. Allow your audience to participate. Enrich people's experience by turning them on to other groups that offer unique and interesting information. Collaborate with other communicators with the goal of providing the public with simple, clear messages, repeated by a variety of trusted sources.

Forty-three ongoing technology transfer programs in Federal agencies other than NASA were selected from over 200 current Federal technology transfer activities. Selection was made and specific technology transfer mechanisms utilized. Detailed information was obtained on the selected programs by reviewing published literature, and conducting telephone interviews with each program manager. Specific information collected on each program includes technology areas; user groups, mechanisms employed, duration of program, and level of effort. Twenty-four distinct mechanisms are currently employed in Federal technology transfer activities totaling $260 million per year. Typical applications of each mechanism were reviewed, and caveats on evaluating program effectiveness were discussed. A review of recent federally funded research in technology transfer to state and local governments was made utilizing the Smithsonian Science Information Exchange, and abstracts of interest to NASA were selected for further reference.

Addressing global sustainability challenges--including climate change, resource depletion, and ecosystem loss--is beyond the individual capabilities of even the largest companies. To tackle these threats, and unleash new value, companies and other stakeholders must collaborate in new ways that treat fragile and complex ecosystems as a whole. In this article, the authors draw on cases including the Latin American Water Funds Partnership, the Sustainable Apparel Coalition (led by Nike, Patagonia, and Walmart), and Action to Accelerate Recycling (a partnership between Alcoa, consumer packaged goods companies, and local governments, among others) to describe four new collaboration models that create shared value and address environmental protection across the value stream. Optimal collaborations focus on improving either business processes or outcomes. They start with a small group of key organizations, bring in project management expertise, link self-interest to shared interest, encourage productive competition, create quick wins, and, above all, build and maintain trust.

Individual interest, something that persists regardless of the situation, and situational interest, finding personal value in an educational context, have not been studied in medical student education. To determine if individualized case discussions enhance interest in pediatric medicine. During the 2008/2009 academic year, 88 clerkship students participated in clinical case discussions. At orientation, students completed an Interest in Pediatrics (IIP) questionnaire, responding 1 = strongly disagree to 5 = strongly agree. Intervention and control groups were randomly assigned. The intervention group personalized cases to students' medical specialty interests. The control group discussed the case presentation. Groups met twice during the 8-week clerkships, completing a post-IIP at the end of the clerkship. Intervention group interest increased from pre-IIP, mean = 3.64, to post-IIP, mean = 4.22 (z = -2.994, p < 0.05, r = -0.44). On post-IIP, application of pediatric medicine increased for both groups; the intervention group was most significant from pre-IIP, mean = 1.09, to post-IIP, mean = 4.33 (z = -6.038, p < 0.05, r = -0.88). Enhanced interest in pediatrics from the intervention group indicates that creating a learning environment personally relevant to students' careers facilitates interest to learn.

Symmetry Analysis of Gauge-Invariant Field Equations via a Generalized Harrison-Estabrook Formalism.

NASA Astrophysics Data System (ADS)

Papachristou, Costas J.

The Harrison-Estabrook formalism for the study of invariance groups of partial differential equations is generalized and extended to equations that define, through their solutions, sections on vector bundles of various kinds. Applications include the Dirac, Yang-Mills, and self-dual Yang-Mills (SDYM) equations. The latter case exhibits interesting connections between the internal symmetries of SDYM and the existence of integrability characteristics such as a linear ("inverse scattering") system and Backlund transformations (BT's). By "verticalizing" the generators of coordinate point transformations of SDYM, nine nonlocal, generalized (as opposed to local, point) symmetries are constructed. The observation is made that the prolongations of these symmetries are parametric BT's for SDYM. It is thus concluded that the entire point group of SDYM contributes, upon verticalization, BT's to the system.

Restricted interests are a class of repetitive behavior in autism spectrum disorders (ASD) whose intensity and narrow focus often contribute to significant interference with daily functioning. While numerous neuroimaging studies have investigated executive circuits as putative neural substrates of repetitive behavior, recent work implicates affective neural circuits in restricted interests. We sought to explore the role of affective neural circuits and determine how restricted interests are distinguished from hobbies or interests in typical development. We compared a group of children with ASD to a typically developing (TD) group of children with strong interests or hobbies, employing parent report, an operant behavioral task, and functional imaging with personalized stimuli based on individual interests. While performance on the operant task was similar between the two groups, parent report of intensity and interference of interests was significantly higher in the ASD group. Both the ASD and TD groups showed increased BOLD response in widespread affective neural regions to the pictures of their own interest. When viewing pictures of other children's interests, the TD group showed a similar pattern, whereas BOLD response in the ASD group was much more limited. Increased BOLD response in the insula and anterior cingulate cortex distinguished the ASD from the TD group, and parent report of the intensity and interference with daily life of the child's restricted interest predicted insula response. While affective neural network response and operant behavior are comparable in typical and restricted interests, the narrowness of focus that clinically distinguishes restricted interests in ASD is reflected in more interference in daily life and aberrantly enhanced insula and anterior cingulate response to individuals' own interests in the ASD group. These results further support the involvement of affective neural networks in repetitive behaviors in ASD. © 2013 The Authors.

Anomalous van der Waals-Casimir interactions on graphene: A concerted effect of temperature, retardation, and non-locality

Dispersion forces play a major role in graphene, largely influencing adhesion of adsorbate moieties and stabilization of functional multilayered structures. However, the reliable prediction of dispersion interactions on graphene up to the relevant ˜10 nm scale is an extremely challenging task: in fact, electromagnetic retardation effects and the highly non-local character of π electrons can imply sizeable qualitative variations of the interaction with respect to known pairwise approaches. Here we address both issues, determining the finite-temperature van der Waals (vdW)-Casimir interaction for point-like and extended adsorbates on graphene, explicitly accounting for the non-local dielectric permittivity. We find that temperature, retardation, and non-locality play a crucial role in determining the actual vdW scaling laws and the stability of both atomic and larger molecular adsorbates. Our results highlight the importance of these effects for a proper description of systems of current high interest, such as graphene interacting with biomolecules, and self-assembly of complex nanoscale structures. Due to the generality of our approach and the observed non-locality of other 2D materials, our results suggest non-trivial vdW interactions from hexagonal mono-layered materials from group 14 of the periodic table, to transition metal dichalcogenides.

Local Health Department Capacity for Community Engagement and Its Implications for Disaster Resilience

Sell, Tara Kirk; Morhard, Ryan

2013-01-01

Over the past decade, community engagement has become a central tenet of US federal doctrine on public health emergency preparedness. Little is known, however, about how the vision of a ready, aware, and involved populace has translated into local practice, or which conditions thus far have advanced community involvement in what is typically considered the province of government authorities and emergency professionals. In 2011-12, to help close that knowledge gap, investigators carried out semistructured qualitative interviews with practitioners (N=25) from 7 local health departments about which conditions have advanced or inhibited community engagement in public health emergency preparedness. Among the organizational factors identified as enabling local health departments' involvement of community residents and groups in emergency preparedness were a supportive agency leadership and culture, sufficient staffing and programmatic funding, interested and willing partners, and external triggers such as federal grants and disaster experiences that spotlighted the importance of community relationships to effective response. Facing budget and staff cuts, local health departments feel increasingly constrained in efforts to build trusted and lasting preparedness ties with community partners. At the same time, some progress in preparedness partnerships may be possible in the context of agency leadership, culture, and climate that affirms the value of collaboration with the community.

Intra-operative, peri-articular injection of local anaesthesia is an increasingly popular way of controlling pain following total knee replacement. At the same time, the problems associated with allogenic blood transfusion have led to interest in alternative methods for managing blood loss after total knee replacement, including the use of auto-transfusion of fluid from the patient's surgical drain. It is safe to combine peri-articular infiltration with auto-transfusion from the drain. We performed a randomised clinical trial to compare the concentration of local anaesthetic in the blood and in the fluid collected in the knee drain in patients having either a peri-articular injection or a femoral nerve block. Clinically relevant concentrations of local anaesthetic were found in the fluid from the drains of patients having peri-articular injections (4.92 μg/ml (sd 3.151)). However, none of the patients having femoral nerve blockade had detectable levels. None of the patients in either group had clinically relevant concentrations of local anaesthetic in their blood after re-transfusion. The evidence from this study suggests that it is safe to use peri-articular injection in combination with auto-transfusion of blood from peri-articular drains during knee replacement surgery.

Radical prostatectomy (RP), external beam radiation (XRT) and brachytherapy (BTX) are the most commonly used treatments for localized prostate cancer. We studied whether patient personality influences treatment choice and overall treatment satisfaction. From 1998 to 2002, 219 consecutive patients treated with RP (n = 74), XRT (n = 73), or BTX (n = 72) at our institution who remained free of biochemical recurrence were sent the Big Five Inventory (BFI) and a satisfaction/treatment participation questionnaire. We compared personality, satisfaction and participation scores between the three groups. Correlation between personality and satisfaction was determined. Multivariate regression was used to determine association between personality and satisfaction/participation after controlling for patient- and disease-related factors. Higher mean satisfaction and participation scores were observed within the RP and XRT groups, respectively (P = NS). No significant differences in personality were observed between groups. XRT patients tended to have higher extroversion, openness and agreeability scores, while RP patients tended to be more neurotic and conscientious (all P = NS). After controlling for other factors, a negative correlation was found between openness scores and satisfaction and a positive correlation between conscientiousness scores and satisfaction. Specific personality traits were associated with interest in participation in care for both RP and BTX patients but not for XRT patients. There are mild variations in personality as measured by the BFI between patients undergoing treatment for localized prostate cancer. Certain BFI-measured personality traits may be associated with levels of satisfaction following therapy. Disease concerns and provider recommendations may override the influence of personality in the decision-making process.

A quantitative method is presented for studying the pattern of metabolic activity in a set of Positron Emission Transaxial Tomography (PETT) images. Using complex Fourier coefficients as a feature vector for each image, cluster, principal components, and discriminant function analyses are used to empirically describe metabolic differences between control subjects and patients with DSM III diagnosis for schizophrenia or endogenous depression. We also present data on the effects of neuroleptic treatment on the local cerebral metabolic rate of glucose utilization (LCMRGI) in a group of chronic schizophrenics using the region of interest approach. 15 references, 4 figures, 3 tables.

Although much is understood about barriers to healthy food consumption in low-income, urban communities, knowledge regarding the crucial next step of building feasible, community-supported approaches to address those barriers remains limited. This qualitative study used in-depth interviews (n = 20), focus groups (n = 2), and participant observations (n = 3) to identify strategies to promote locally grown produce from an urban food security project, Produce From the Park (PFP), an urban farm. Informants included community organization representatives and residents from low-income neighborhoods in a mid-Atlantic city. Informants identified structural and cultural barriers to purchasing healthy food, including price, location, food culture, and lack of interest. Participants proposed a number of strategies, such as distribution through mobile food carts and farm stands, marketing new foods through taste tests and cooking demonstrations, and youth mentorship. Informants also described their perceptions of the local urban farm and suggested ways to increase community buy-in. Strategies mentioned were inexpensive and incorporated cultural norms and local assets. These community perspectives can provide insights for those promoting healthy eating in urban African American communities through urban food security projects.

This article describes the approach of the KIWAKKUKI women's group in helping to change sex behavior among youth and to inform community women's groups in Moshi, Tanzania. The group concluded after four years of experience that people change risky sexual behavior most when participatory methods based on local culture are used in educational programs. KIWAKKUKI established discussion groups for primary and secondary school students in the schools. The approach included use of videos, clothboards, chalkboards, and sometimes role plays. The mothers engaged in discussions with children other than their own, which reduced some embarrassment. Sex education discussion groups were also conducted among church youth and community women's groups. Monthly meetings drew a membership of about 356 persons, of whom 30-50 were trainers and advocates. Some of the topics of conversation were knowledge about physical bodies and personalities, assertiveness and the ability to say "no," laws and regulations relating to marriage, inheritance, sexual harassment, abuse, and AIDS. Other topics focused on the cultural understanding of circumcision, teeth extraction, wife inheritance, and women's income generation. The basic premise of their operation is empowerment of women and the belief that women can make a difference in changing culture. Men, who indicated an interest in forming a group, were redirected to their own group formation.

Background Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Methodology/Principal Findings Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Conclusions/Significance Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF. PMID:26849126

Primary endpoint was to report polypharmacy distribution in the general population vs ≥65 years old people and to examine the frequency of drug-drug interactions (DDIs) in the Health Local Unit of Palermo, Italy, in relationship with patients' age. Drug prescription data for the year 2014 were extracted from the database of the Local Health Unit of Palermo Province, Italy. Patients were divided into five age groups (0-13, 14-64, 65-69, 70-74, and ≥75 year old). The detection of potential DDIs in polypharmacy profiles was performed with NavFarma software (Infologic srl, Padova, Italia), with DDI classification provided by tool Micromedex Drug Reax (Truven Health Analitics, Michigan, USA). We analyzed data of 1,324,641 patients, and 15,801,191 medical prescription were recorded; of these, 11,337,796 regarded chronic conditions. The drug prescriptions reached the highest values in the 65-69 and 70-74 age groups (p = 0.005 and p = 0.008 vs age 14-64 respectively). An overall amount of 6,094,373 DDIs were detected, of which 47,173 were contraindicated. Median number of DDIs was higher in 65-69 and 70-74 age groups (p = 0.008 and p = 0.012 vs age 14-64, respectively). Regarding contraindicated DDIs a significant difference was detected comparing 14-64 vs ≥65 age groups (p = 0.010 vs 65-69 group, p = 0.005 vs 70-74 group and ≥75 group). Polypharmacy is a phenomenon acquiring increasing dimensions also in our province. It interests particularly the older subjects, and assumes a dramatic accent when it is put in relationship with the frequency of DDIs. A proactive vigilance about potential life threatening drug interactions is mandatory.

Multimodal sparse reconstruction in guided wave imaging of defects in plates

NASA Astrophysics Data System (ADS)

Golato, Andrew; Santhanam, Sridhar; Ahmad, Fauzia; Amin, Moeness G.

2016-07-01

A multimodal sparse reconstruction approach is proposed for localizing defects in thin plates in Lamb wave-based structural health monitoring. The proposed approach exploits both the sparsity of the defects and the multimodal nature of Lamb wave propagation in plates. It takes into account the variation of the defects' aspect angles across the various transducer pairs. At low operating frequencies, only the fundamental symmetric and antisymmetric Lamb modes emanate from a transmitting transducer. Asymmetric defects scatter these modes and spawn additional converted fundamental modes. Propagation models are developed for each of these scattered and spawned modes arriving at the various receiving transducers. This enables the construction of modal dictionary matrices spanning a two-dimensional array of pixels representing potential defect locations in the region of interest. Reconstruction of the region of interest is achieved by inverting the resulting linear model using the group sparsity constraint, where the groups extend across the various transducer pairs and the different modes. The effectiveness of the proposed approach is established with finite-element scattering simulations of the fundamental Lamb wave modes by crack-like defects in a plate. The approach is subsequently validated with experimental results obtained from an aluminum plate with asymmetric defects.

Intracellular Localization of Arabidopsis Sulfurtransferases1

2004-01-01

Sulfurtransferases (Str) comprise a group of enzymes widely distributed in archaea, eubacteria, and eukaryota which catalyze the transfer of a sulfur atom from suitable sulfur donors to nucleophilic sulfur acceptors. In all organisms analyzed to date, small gene families encoding Str proteins have been identified. The gene products were localized to different compartments of the cells. Our interest concerns the localization of Str proteins encoded in the nuclear genome of Arabidopsis. Computer-based prediction methods revealed localization in different compartments of the cell for six putative AtStrs. Several methods were used to determine the localization of the AtStr proteins experimentally. For AtStr1, a mitochondrial localization was demonstrated by immunodetection in the proteome of isolated mitochondria resolved by one- and two-dimensional gel electrophoresis and subsequent blotting. The respective mature AtStr1 protein was identified by mass spectrometry sequencing. The same result was obtained by transient expression of fusion constructs with the green fluorescent protein in Arabidopsis protoplasts, whereas AtStr2 was exclusively localized to the cytoplasm by this method. Three members of the single-domain AtStr were localized in the chloroplasts as demonstrated by transient expression of green fluorescent protein fusions in protoplasts and stomata, whereas the single-domain AtStr18 was shown to be cytoplasmic. The remarkable subcellular distribution of AtStr15 was additionally analyzed by transmission electron immunomicroscopy using a monospecific antibody against green fluorescent protein, indicating an attachment to the thylakoid membrane. The knowledge of the intracellular localization of the members of this multiprotein family will help elucidate their specific functions in the organism. PMID:15181206

Aid in the midst of plenty: oil wealth, misery and advocacy in Angola.

PubMed

Le Billon, Philippe

2005-03-01

This paper examines advocacy initiatives by humanitarian and human rights organisations to address problems of governance in resource-rich and conflict-affected countries, focussing on the case of Angola. Humanitarian principles preclude the use of indiscriminate conditionality and point towards a cautious approach to advocacy aimed at assisting vulnerable populations. Furthermore, the relatively insignificant amount of aid supplied to resource-rich local authorities means that individual agencies have precious little leverage, especially when commercial interests rather than humanitarian or 'good governance' principles influence the priorities of bilateral donors. A context of resource wealth calls for: high levels of coordination and cooperation between human rights groups, aid agencies and donors; balanced use of conditionality, based on the drawing, by donors, of a clear distinction between emergency and development-oriented assistance; and a sustained effort to highlight the responsibilities of local authorities, foreign governments and businesses in meeting humanitarian and development objectives.

Heat and Health in a Changing Climate: Building a Decision Support Tool for California Public Health Officials

NASA Astrophysics Data System (ADS)

Steinberg, N.

2017-12-01

There is considerable interest in overlaying climate projections with social vulnerability maps as a mechanism for targeting community adaptation efforts. Yet the identification of relevant factors for adaptation- and resilience-based decisions remain a challenge. Our findings show that successful adaptation interventions are more likely when factors are grouped and spatially represented. By designing a decision-support tool that is focused on informing long-term planning to mitigate the public health impacts of extreme heat, communities can more easily integrate climate, land use, and population characteristics into local planning processes. The ability to compare risks and potential health impacts across census tracts may also position local practitioners to leverage scarce resources. This presentation will discuss the information gaps identified by planners and public health practitioners throughout California and illustrate the spatial variations of key health risk factors.

We introduce a method to obtain the specific heat of quantum impurity models via a direct calculation of the impurity internal energy requiring only the evaluation of local quantities within a single numerical renormalization group (NRG) calculation for the total system. For the Anderson impurity model we show that the impurity internal energy can be expressed as a sum of purely local static correlation functions and a term that involves also the impurity Green function. The temperature dependence of the latter can be neglected in many cases, thereby allowing the impurity specific heat Cimp to be calculated accurately from local static correlation functions; specifically via Cimp=(∂Eionic)/(∂T)+(1)/(2)(∂Ehyb)/(∂T), where Eionic and Ehyb are the energies of the (embedded) impurity and the hybridization energy, respectively. The term involving the Green function can also be evaluated in cases where its temperature dependence is non-negligible, adding an extra term to Cimp. For the nondegenerate Anderson impurity model, we show by comparison with exact Bethe ansatz calculations that the results recover accurately both the Kondo induced peak in the specific heat at low temperatures as well as the high-temperature peak due to the resonant level. The approach applies to multiorbital and multichannel Anderson impurity models with arbitrary local Coulomb interactions. An application to the Ohmic two-state system and the anisotropic Kondo model is also given, with comparisons to Bethe ansatz calculations. The approach could also be of interest within other impurity solvers, for example, within quantum Monte Carlo techniques.

The oxygen present in a human organism comes from numerous sources, but the major factor that causes variation in the isotopic composition of this element in a tissue is available drinking water. The isotopic ratio of oxygen in an organism's tissue, including that found in bones and teeth, reflects the isotopic oxygen composition typical for the area where a given individual developed and lived. Of particular interest with regard to this issue were a series of skeletons from the multiple grave discovered at the Funnel Beaker-Baden settlement at Bronocice (southern Poland). The question therefore arose whether the specimens buried in this grave were part of the local community. The oxygen isotope level was established using apatite isolated from bones or teeth. A femur and root dentine samples taken from permanent teeth were subjected to oxygen isotope analysis. The oxygen isotope level of the site was established on the basis of local water precipitation and measurements taken from the oxygen isotope concentration in apatite samples isolated from the bones of animals co-occurring with the studied human group. It has been found that the oxygen isotope levels in the bones and dentine of almost all the analysed specimens from the excavated site at Bronocice were within the established range for the area's environment, providing evidence for their local origin. Thus, it can be assumed that the analysed group inhabiting the macrosettlement at Bronocice during the Funnel Beaker phase of the Baden culture was most probably of local origin.

Minority business bidding for local government contracts: the complexity of availability.

PubMed

Bangs, Ralph L; Murrell, Audrey; Constance-Huggins, Monique

2007-01-01

While minority-business enterprises (MBEs) have gained some access to local government contracts during the last three decades, these firms continue to receive a small share of local government contract spending relative to the number of available firms. Researchers have suggested two general explanations for the low representation of MBEs in contract awards: (1) lack of qualifications and capacity among MBEs, and (2) public and private discrimination against MBEs in contracting processes. This study on prime contract opportunities in a Northern central city and county with a large minority population finds that low bid rates greatly contribute to the low MBE shares of prime contracts and that bidding is reduced by both local government processes and characteristics of the firms. Some implications of these findings are that local governments need to: (1) monitor MBE shares of prime contract bids by size of contract and use share of bids as one measure of program and organizational effectiveness; (2) identify MBEs that are qualified for prime contracts and encourage and help interested firms to submit competitive bids; and (3) ensure that local government policies and practices do not diminish access to information about prime contract opportunities for qualified and interested minority firms. Another implication is that bidders lists should not be a primary basis for determining MBE availability, since many qualified and interested MBEs do not bid because of perceived barriers in local government.

The connection among boundary layer phenomena, atmospheric pollutant dynamics and human health is an established fact, taking many different forms depending on local characteristics, including slope and position of relief and/or coastline, surface roughness, emission patterns. The problem is especially interesting in complex and coastal terrain, where concurrence of slope and sea induced local circulation interact reciprocally, yielding a complex pattern whose interpretation may go beyond pure modeling, and devise specific measurements among which the planetary boundary layer (PBL) height. An occasion for studying this important theme has been offered by Regione Molise and Valle del Biferno Consortium (COSIB), for the specific case of the industrial complex of Valle del Biferno, 3 km inland of Termoli, in Central Italy, on the Adriatic coast. The local government, sensitive to air quality and public health in the industrial area, together with COSIB has co-financed a research project aimed at gaining knowledge about local meteorology, PBL phenomena and atmospheric pollutant dispersion in the area. Expected results include new air quality monitoring and control methodologies in Valle del Biferno for a sustainable development in an environmentally respectful manner, at a site already characterized by a high environmental and landscape value. The research project, developed by ENEA, has began in 2007 and will conclude in December 2010. Project activities involve research group from Europe, the United States of America, and the Russian Federation. Scientific and practical results will be published and presented in occasion of the final workshop to be held on project conclusion. The scientific interest of Valle del Biferno case stems from the specific local characteristics at site. Given the valley orientation respect to mean synoptic circulation, local effects as sea and slope breezes are dominant, and a complex wind regime develops affecting local transport and diffusion of pollutants emitted in the area of the industrial complex. All effects studied, although influenced by local conditions, characterize not only this industrial area but all areas located along the coastline. This location is highly frequent in Italy and the World, as most industrial complexes in the World occur at coastal sites, where access to harbors and transport networks are facilitated. The Valle del Biferno case may then yield important data to many industrial sites.

Genotyping by sequencing is suitable for analysis of global diversity in maize. We showed the distinctiveness of flint maize inbred lines of interest to enrich the diversity of breeding programs. Genotyping-by-sequencing (GBS) is a highly cost-effective procedure that permits the analysis of large collections of inbred lines. We used it to characterize diversity in 1191 maize flint inbred lines from the INRA collection, the European Cornfed association panel, and lines recently derived from landraces. We analyzed the properties of GBS data obtained with different imputation methods, through comparison with a 50 K SNP array. We identified seven ancestral groups within the Flint collection (dent, Northern flint, Italy, Pyrenees-Galicia, Argentina, Lacaune, Popcorn) in agreement with breeding knowledge. Analysis highlighted many crosses between different origins and the improvement of flint germplasm with dent germplasm. We performed association studies on different agronomic traits, revealing SNPs associated with cob color, kernel color, and male flowering time variation. We compared the diversity of both our collection and the USDA collection which has been previously analyzed by GBS. The population structure of the 4001 inbred lines confirmed the influence of the historical inbred lines (B73, A632, Oh43, Mo17, W182E, PH207, and Wf9) within the dent group. It showed distinctly different tropical and popcorn groups, a sweet-Northern flint group and a flint group sub-structured in Italian and European flint (Pyrenees-Galicia and Lacaune) groups. Interestingly, we identified several selective sweeps between dent, flint, and tropical inbred lines that co-localized with SNPs associated with flowering time variation. The joint analysis of collections by GBS offers opportunities for a global diversity analysis of maize inbred lines.

Today's world is dominated by a wide range of informatics tools that are readily available to a wide range of stakeholders. There is growing recognition that the appropriate involvement of local communities in land and water management decisions can result in multiple environmental, economic and social benefits. Therefore, local stakeholder groups are increasingly being asked to participate in decision making alongside policy makers, government agencies and scientists. As such, addressing flooding issues requires new ways of engaging with the catchment and its inhabitants at a local level. To support this, new tools and approaches are required. The growth of cloud based technologies offers new novel ways to facilitate this process of exchange of information in earth sciences. The Environmental Virtual Observatory Pilot project (EVOp) is a new initiative from the UK Natural Environment Research Council (NERC) designed to deliver proof of concept for new tools and approaches to support the challenges as outlined above (http://www.evo-uk.org/). The long term vision of the Environmental Virtual Observatory is to: • Make environmental data more visible and accessible to a wide range of potential users including public good applications; • Provide tools to facilitate the integrated analysis of data, greater access to added knowledge and expert analysis and visualisation of the results; • Develop new, added-value knowledge from public and private sector data assets to help tackle environmental challenges. As part of the EVO pilot, an interactive cloud based tool has been developed with local stakeholders. The Local Landscape Visualisation Tool attempts to communicate flood risk in local impacted communities. The tool has been developed iteratively to reflect the needs, interests and capabilities of a wide range of stakeholders. This tool (assessable via a web portal) combines numerous cloud based tools and services, local catchment datasets, hydrological models and novel visualisation techniques. This pilot tool has been developed by engaging with different stakeholder groups in three catchments in the UK; the Afon Dyfi (Wales), the River Tarland (Scotland) and the River Eden (England). Stakeholders were interested in accessing live data in their catchments and looking at different land use change scenarios on flood peaks. Visualisation tools have been created which offer access to real time data (such as river level, rainfall and webcam images). Other tools allow land owners to use cloud based models (example presented here uses Topmodel, a rainfall-runoff model, on a custom virtual machine image on Amazon web services) and local datasets to explore future land use scenarios, allowing them to understand the associated flood risk. Different ways to communicate model uncertainty are currently being investigated and discussed with stakeholders. In summary the pilot project has had positive feedback and has evolved into two unique parts; a web based map tool and a model interface tool. Users can view live data from different sources, combine different data types together (data mash-up), develop local scenarios for land use and flood risk and exploit the dynamic, elastic cloud modelling capability. This local toolkit will reside within a wider EVO platform that will include national and global datasets, models and state of the art cloud computer systems.

The relationship between social capital (support, trust, patient awareness, and increased practice revenue) and local networks (university hospital) in communities has received little attention. The development of computer-based communication networks (social networks) has added a new dimension to the argument, posing the question of whether local networks can (re-)create social capital in local communities. This relationship is examined through a review of the literature on local networks and social capital and a surgeon's practice management from 1990 to 2001 with respect to repair of pectus chest deformities. With respect to pectus repair there was a consistent but small number of new referrals (15-20 new patients/year), lack of patient awareness (eight to 12 self-referred patients/year), and modest practice revenue. Since the inception of an Internet website (social network) dedicated to pectus repair in 1996 there has been increased social participation (n = 630 hits/year to the website); facilitation of spread of information through E-mail messages (n = 430 messages/year); and a greater participation of groups such as women, minorities, adults, and those with disability (n = 120 patients/year). The dissemination of information via the local network has also allowed an "outward movement" with increased participation by interconnecting communities (n = 698,300 global Internet participants based on statistical ratios). We conclude that local networks have enhanced social networks providing new grounds for the development of relationships based on choice and shared interest.

Sexual selection affects local extinction and turnover in bird communities

Predicting extinction risks has become a central goal for conservation and evolutionary biologists interested in population and community dynamics. Several factors have been put forward to explain risks of extinction, including ecological and life history characteristics of individuals. For instance, factors that affect the balance between natality and mortality can have profound effects on population persistence. Sexual selection has been identified as one such factor. Populations under strong sexual selection experience a number of costs ranging from increased predation and parasitism to enhanced sensitivity to environmental and demographic stochasticity. These findings have led to the prediction that local extinction rates should be higher for species/populations with intense sexual selection. We tested this prediction by analyzing the dynamics of natural bird communities at a continental scale over a period of 21 years (1975-1996), using relevant statistical tools. In agreement with the theoretical prediction, we found that sexual selection increased risks of local extinction (dichromatic birds had on average a 23% higher local extinction rate than monochromatic species). However, despite higher local extinction probabilities, the number of dichromatic species did not decrease over the period considered in this study. This pattern was caused by higher local turnover rates of dichromatic species, resulting in relatively stable communities for both groups of species. Our results suggest that these communities function as metacommunities, with frequent local extinctions followed by colonization. Anthropogenic factors impeding dispersal might therefore have a significant impact on the global persistence of sexually selected species.

Can the Discrepancy between Locally and Globally Derived Neutral Hydrogen Mass Functions be Explained by a Varying Value of M ⋆?

NASA Astrophysics Data System (ADS)

Minchin, Robert F.

2017-09-01

I investigate whether it is possible to reconcile the recent Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) observation that the neutral hydrogen mass function (HIMF) across different galactic densities has the same, non-flat, faint-end slope, with observations of isolated galaxies and many galaxy groups that show their HIMFs to have flat faint-end slopes. I find that a fairly simple model in which the position of the knee in the mass function of each individual group is allowed to vary is able to account for both of these observations. If this model reflects reality, the ALFALFA results point to an interesting “conspiracy” whereby the differing group HIMFs always sum up to form global HIMFs with the same faint-end slope in different environments. More generally, this result implies that global environmental HIMFs do not necessarily reflect the HIMFs in individual groups belonging to that environment and cannot be used to directly measure variations in group-specific HIMFs with environment.

The aim of this study is to describe clinical nurse specialists' characteristics, interest, confidence, motivators, and barriers in conducting research. This study was a descriptive, multicohort design. Clinical nurse specialists were recruited electronically through national and local organizations to complete anonymous surveys 3 times, over 3 years. Comparative analyses included χ and Kruskal-Wallis tests. Of 2052 responders (initial, n = 629; 18 months, n = 465; and 3 years, n = 958), mean (SD) participant age was 50.3 (9.3) years. Overall, 41.7% of participants were involved as principal or coinvestigators in research. Interest in conducting nursing research (on a 0-100 scale) was 61.1 (38.4) and was lowest among the 18-month time point participant group (score, 39.1 [32.2]) and highest at the 3-year time point (68.3, [30.7]; P < .001). Confidence in conducting research, discussion of statistics, and perceptions of motivators and barriers to conducting research did not differ across time period groups. Access to literature and mentors and research knowledge were the most prevalent barriers to conducting research. Less than 42% of clinical nurse specialists conducted research and the rate did not change between different time groups. Access and knowledge barriers to conducting research were prominent. Workplace leaders need to consider resources and support of academic educational opportunities to increase research conduct by clinical nurse specialists.

A systems approach for the development of a sustainable community--the application of the sensitivity model (SM).

Chan, Shih-Liang; Huang, Shu-Li

2004-09-01

Corresponding to the concept of 'Think globally, act locally and plan regionally' of sustainable development, this paper discusses the approach of planning a sustainable community in terms of systems thinking. We apply a systems tool, the sensitivity model (SM), to build a model of the development of the community of Ping-Ding, located adjacent to the Yang-Ming-Shan National Park, Taiwan. The major issue in the development of Ping-Ding is the conflict between environmental conservation and the development of a local tourism industry. With the involvement of local residents, planners, and interest groups, a system model of 26 variables was defined to identify characteristics of Ping-Ding through pattern recognition. Two scenarios concerning the sustainable development of Ping-Ding are simulated with interlinked feedbacks from variables. The results of the analysis indicate that the development of Ping-Ding would be better served by the planning of agriculture and the tourism industry. The advantages and shortfalls of applying SM in the current planning environment of Taiwan are also discussed to conclude this paper.

Visual Phonetic Processing Localized Using Speech and Non-Speech Face Gestures in Video and Point-Light Displays

The talking face affords multiple types of information. To isolate cortical sites with responsibility for integrating linguistically relevant visual speech cues, speech and non-speech face gestures were presented in natural video and point-light displays during fMRI scanning at 3.0T. Participants with normal hearing viewed the stimuli and also viewed localizers for the fusiform face area (FFA), the lateral occipital complex (LOC), and the visual motion (V5/MT) regions of interest (ROIs). The FFA, the LOC, and V5/MT were significantly less activated for speech relative to non-speech and control stimuli. Distinct activation of the posterior superior temporal sulcus and the adjacent middle temporal gyrus to speech, independent of media, was obtained in group analyses. Individual analyses showed that speech and non-speech stimuli were associated with adjacent but different activations, with the speech activations more anterior. We suggest that the speech activation area is the temporal visual speech area (TVSA), and that it can be localized with the combination of stimuli used in this study. PMID:20853377

Stakeholders are people with an interest in a topic. Internationally, stakeholder involvement in palliative care research and health technology assessment requires development. Stakeholder involvement adds value throughout research (from prioritising topics to disseminating findings). Philosophies and understandings about the best ways to involve stakeholders in research differ internationally. Stakeholder involvement took place in seven countries (England, Germany, Italy, Lithuania, the Netherlands, Norway and Poland). Findings informed a project that developed concepts and methods for health technology assessment and applied these to evaluate models of palliative care service delivery. To report on stakeholder involvement in the INTEGRATE-HTA project and how issues identified informed project development. Using stakeholder consultation or a qualitative research design, as appropriate locally, stakeholders in seven countries acted as 'advisors' to aid researchers' decision making. Thematic analysis was used to identify key issues across countries. A total of 132 stakeholders (82 professionals and 50 'lay' people) aged ⩾18 participated in individual face-to-face or telephone interviews, consultation meetings or focus groups. Different stakeholder involvement methods were used successfully to identify key issues in palliative care. A total of 23 issues common to three or more countries informed decisions about the intervention and comparator of interest, sub questions and specific assessments within the health technology assessment. Stakeholders, including patients and families undergoing palliative care, can inform project decision making using various involvement methods according to the local context. Researchers should consider local understandings about stakeholder involvement as views of appropriate and feasible methods vary. Methods for stakeholder involvement, especially consultation, need further development.

Implementation of graphic health warning labels on tobacco products in India: the interplay between the cigarette and the bidi industries.

To understand the competition between and among tobacco companies and health groups that led to graphical health warning labels (GHWL) on all tobacco products in India. Analysis of internal tobacco industry documents in the Legacy Tobacco Document Library, documents obtained through India's Right to Information Act, and news reports. Implementation of GHWLs in India reflects a complex interplay between the government and the cigarette and bidi industries, who have shared as well as conflicting interests. Joint lobbying by national-level tobacco companies (that are foreign subsidiaries of multinationals) and local producers of other forms of tobacco blocked GHWLs for decades and delayed the implementation of effective GHWLs after they were mandated in 2007. Tobacco control activists used public interest lawsuits and the Right to Information Act to win government implementation of GHWLs on cigarette, bidi and smokeless tobacco packs in May 2009 and rotating GHWLs in December 2011. GHWLs in India illustrate how the presence of bidis and cigarettes in the same market creates a complex regulatory environment. The government imposing tobacco control on multinational cigarette companies led to the enforcement of regulation on local forms of tobacco. As other developing countries with high rates of alternate forms of tobacco use establish and enforce GHWL laws, the tobacco control advocacy community can use pressure on the multinational cigarette industry as an indirect tool to force implementation of regulations on other forms of tobacco.

The Afro-Arabian Paleogene fossil record of Chiroptera is very poor. In North Africa and Arabia, this record is limited, thus far, to a few localities mainly in Tunisia (Chambi, late early Eocene), Egypt (Fayum, late Eocene to early Oligocene), and Sultanate of Oman (Taqah, early Oligocene). It consists primarily of isolated teeth or mandible fragments. Interestingly, these African fossil bats document two modern groups (Vespertilionoidea and Rhinolophoidea) from the early Eocene, while the bat fossil record of the same epoch of North America, Eurasia, and Australia principally includes members of the "Eochiroptera." This paraphyletic group contains all primitive microbats excluding modern families. In Algeria, the region of Brezina, southeast of the Atlas Mountains, is famous for the early Eocene El Kohol Formation, which has yielded one of the earliest mammalian faunas of the African landmass. Recent fieldwork in the same area has led to the discovery of a new vertebrate locality, including isolated teeth of Chiroptera. These fossils represent the oldest occurrence of Chiroptera in Africa, thus extending back the record of the group to the middle early Eocene (Ypresian) on that continent. The material consists of an upper molar and two fragments of lower molars. The dental character association matches that of "Eochiroptera." As such, although very fragmentary, the material testifies to the first occurrence of "Eochiroptera" in Algeria, and by extension in Africa. This discovery demonstrates that this basal group of Chiroptera had a worldwide distribution during the early Paleogene.

Documenting Differences between Early Stone Age Flake Production Systems: An Experimental Model and Archaeological Verification.

2015-01-01

This study investigates morphological differences between flakes produced via "core and flake" technologies and those resulting from bifacial shaping strategies. We investigate systematic variation between two technological groups of flakes using experimentally produced assemblages, and then apply the experimental model to the Cutting 10 Mid -Pleistocene archaeological collection from Elandsfontein, South Africa. We argue that a specific set of independent variables--and their interactions--including external platform angle, platform depth, measures of thickness variance and flake curvature should distinguish between these two technological groups. The role of these variables in technological group separation was further investigated using the Generalized Linear Model as well as Linear Discriminant Analysis. The Discriminant model was used to classify archaeological flakes from the Cutting 10 locality in terms of their probability of association, within either experimentally developed technological group. The results indicate that the selected independent variables play a central role in separating core and flake from bifacial technologies. Thickness evenness and curvature had the greatest effect sizes in both the Generalized Linear and Discriminant models. Interestingly the interaction between thickness evenness and platform depth was significant and played an important role in influencing technological group membership. The identified interaction emphasizes the complexity in attempting to distinguish flake production strategies based on flake morphological attributes. The results of the discriminant function analysis demonstrate that the majority of flakes at the Cutting 10 locality were not associated with the production of the numerous Large Cutting Tools found at the site, which corresponds with previous suggestions regarding technological behaviors reflected in this assemblage.

From Data Refuge to the Libraries+ Network: New Partnerships and Ideas for Ensuring Continued Access to Federal Data

NASA Astrophysics Data System (ADS)

Janz, M.

2017-12-01

Data Refuge began as concerns grew about the vulnerability of federal climate and environmental data. The project began by hosting a Data Rescue event that intended to educate attendees about the risks that exist for digital information, advocate for the many local uses of climate and environmental data, and create research copies of federal climate and environmental data that would be held off federal servers. This workflow was used by many other Data Rescue events over the next few months and caught the attention of many interested groups. Those groups included federal agencies, data managers and curators, open data and open government proponents, and librarians and archivists. The Data Refuge project team brought these stakeholders together at the Libraries+ Network meeting to talk about this complicated problem space and to encourage new partnerships to experiment with solutions. The team at University of Pennsylvania is working on federal, regional, and local projects that address some aspects of the problem while many other organizations and universities are working on others. This talk will serve as an update on those projects, the lessons learned from them, and the challenges that remain.

The best practices cover all phases of the wind energy development process - from the policies that allow for wind development, to the sustainable operation of a wind project, to the best practices for decommissioning a spent turbine - including applications for offshore wind. Each best practice describes the opportunities and challenges (pros and cons), and offers a case example that illustrates how that best practice is being utilized by a particular jurisdiction or wind project. The practices described in this publication were selected by amore » diverse group of interests from the Great Lakes Wind Collaborative that included environmental groups, industry, academia, and federal, state and local government regulators. The practices were identified through a year-long process that included a literature review, online survey and interviews with individuals from the public, private and non-profit sectors. Optimally, a suite of these best practices would be applied in an appropriate combination to fit the conditions of a particular wind project or a set of wind projects within a given locality or region.« less

Men's health promotion interventions: what have we learned from previous programmes.

2013-11-01

Concern persists in health-related literature about men's reduced life expectancy and higher premature death rates; this is often linked to difficulties in engaging with men as a client group. However, some innovative projects and programmes, often led by health visitors or other community based nurses, have developed successful health promotion work with men. This article collates existing tacit knowledge (previous learning) about men's health interventions by integrating interview data from nine practitioners who have established such initiatives with data from 35 men's health project reports to consider 'what works'. Five themes stood out as being significant across the data reviewed: using the right setting (often outside statutory services); ensuring the right approach (drawing on male-specific interests and language); actively listening to what local men say; appropriate training (initial and ongoing) for those involved in such work; and partnership working with local community groups, businesses and statutory service providers. While not a panacea for working with any and all men, these themes form a good basis for successful engagement with men and align well with what a recent review of health visitor interventions suggest works in helping bridge service provision-uptake gaps.

Objectives Clinical trials provide ‘gold standard’ evidence for policy, but insufficient locally relevant trials are conducted in low-income and middle-income countries. Local investigator-initiated trials could generate highly relevant data for national governments, but information is lacking on how to facilitate them. We aimed to identify barriers and enablers to investigator-initiated trials in Ethiopia to inform and direct capacity strengthening initiatives. Design Exploratory, qualitative study comprising of in-depth interviews (n=7) and focus group discussions (n=3). Setting Fieldwork took place in Ethiopia during March 2011. Participants Local health researchers with previous experiences of clinical trials or stakeholders with an interest in trials were recruited through snowball sampling (n=20). Outcome measures Detailed discussion notes were analysed using thematic coding analysis and key themes were identified. Results All participants perceived investigator-initiated trials as important for generating local evidence. System and organisational barriers included: limited funding allocation, weak regulatory and administrative systems, few learning opportunities, limited human and material capacity and poor incentives for conducting research. Operational hurdles were symptomatic of these barriers. Lack of awareness, confidence and motivation to undertake trials were important individual barriers. Training, knowledge sharing and experience exchange were key enablers to trial conduct and collaboration was unanimously regarded as important for improving capacity. Conclusions Barriers to trial conduct were found at individual, operational, organisational and system levels. These findings indicate that to increase locally led trial conduct in Ethiopia, system wide changes are needed to create a more receptive and enabling research environment. Crucially, the creation of research networks between potential trial groups could provide much needed practical collaborative support through sharing of financial and project management burdens, knowledge and resources. These findings could have important implications for capacity-strengthening initiatives but further research is needed before the results can be generalised more widely. PMID:24285629

A large number of health apps are available directly to consumers through app marketplaces. Little information is known, however, about how consumers search for these apps and which factors influence their uptake, adoption, and long-term use. The aim of this study was to understand what people look for when they search for health apps and the aspects and features of those apps that consumers find appealing. Participants were recruited from Northwestern University's Center for Behavioral Intervention Technologies' research registry of individuals with mental health needs. Most participants (n=811) completed a survey asking about their use and interest in health and mental health apps. Local participants were also invited to participate in focus groups. A total of 7 focus groups were conducted with 30 participants that collected more detailed information about their use and interest in health and mental health apps. Survey participants commonly found health apps through social media (45.1%, 366/811), personal searches (42.7%, 346/811), or word of mouth (36.9%, 299/811), as opposed to professional sources such as medical providers (24.6%, 200/811). From the focus groups, common themes related to uptake and use of health apps included the importance of personal use before adoption, specific features that users found desirable, and trusted sources either developing or promoting the apps. As the number of mental health and health apps continue to increase, it is imperative to better understand the factors that impact people's adoption and use of such technologies. Our findings indicated that a number of factors-ease of use, aesthetics, and individual experience-drove adoption and use and highlighted areas of focus for app developers and disseminators. ©Stephen M Schueller, Martha Neary, Kristen O'Loughlin, Elizabeth C Adkins.

ABSTRACT Introduction There is a growing interest in achieving higher survival rates with the lowest morbidity in localized prostate cancer (PC) treatment. Consequently, minimally invasive techniques such as low-dose rate brachytherapy (BT) and robotic-assisted prostatectomy (RALP) have been developed and improved. Comparative analysis of functional outcomes and quality of life in a prospective series of 51BT and 42Da Vinci prostatectomies DV Materials and Methods Comparative analysis of functional outcomes and quality of life in a prospective series of 93 patients with low-risk localized PC diagnosed in 2011. 51patients underwent low-dose rate BT and the other 42 patients RALP. IIEF to assess erectile function, ICIQ to evaluate continence and SF36 test to quality of life wee employed. Results ICIQ at the first revision shows significant differences which favour the BT group, 79% present with continence or mild incontinence, whereas in the DV group 45% show these positive results. Differences disappear after 6 months, with 45 patients (89%) presenting with continence or mild incontinence in the BT group vs. 30 (71%) in the DV group. 65% of patients are potent in the first revision following BT and 39% following DV. Such differences are not significant and cannot be observed after 6 months. No significant differences were found in the comparative analysis of quality of life. Conclusions ICIQ after surgery shows significant differences in favour of BT, which disappear after 6 months. Both procedures have a serious impact on erectile function, being even greater in the DV group. Differences between groups disappear after 6 months. PMID:28128908

Simultaneous control of emission localization and two-photon absorption efficiency in dissymmetrical chromophores

Tretiak, Sergei

2009-01-01

The aim of the present work is to demonstrate that combined spectral tuning of fluorescence and two-photon absorption (TPA) properties of multipolar chromophores can be achieved by introduction of slight electronic chemical dissymmetry. In that perspective, two novel series of structurally related chromophores have been designed and studied: a first series based on rod-like quadrupolar chromophores bearing different electron-donating (D) end groups and a second series based on three-branched octupolar chromophores built from a trigonal donating moiety and bearing various acceptor (A) peripheral groups. The influence of the electronic dissymmetry is investigated by combined experimental and theoretical studies of themore » linear and nonlinear optical properties of dissymmetric chromophores compared to their symmetrical counterparts. In both types of systems (i.e. quadrupoles and octupoles) experiments and theory reveal that excitation is essentially delocalized and that excitation involves synchronized charge redistribution between the different D and A moieties within the multipolar structure (i.e. concerted intramolecular charge transfer). In contrast, the emission stems only from a particular dipolar subunit bearing the strongest D or A moieties due to fast excitation localization after excitation prior to emission. Hence control of emission characteristics (polarization and emission spectrum) in addition to localization can be achieved by controlled introduction of electronic dissymmetry (i.e. replacement of one of the D or A end-groups by a slightly stronger D{prime} or A{prime} units). Interestingly dissymmetrical functionalization of both quadrupolar and octupolar compounds does not lead to significant loss in TPA responses and can even be beneficial due to the spectral broadening and peak position tuning that it allows. This study thus reveals an original molecular engineering route strategy allowing major TPA enhancement in multipolar structures due to concerted multidimensional ICT while providing for spatial control of emission localization. Such route could be extended to more intricate (dendritic) and multipolar systems (3D).« less

Group theoretical methods and wavelet theory: coorbit theory and applications

NASA Astrophysics Data System (ADS)

Feichtinger, Hans G.

2013-05-01

Before the invention of orthogonal wavelet systems by Yves Meyer1 in 1986 Gabor expansions (viewed as discretized inversion of the Short-Time Fourier Transform2 using the overlap and add OLA) and (what is now perceived as) wavelet expansions have been treated more or less at an equal footing. The famous paper on painless expansions by Daubechies, Grossman and Meyer3 is a good example for this situation. The description of atomic decompositions for functions in modulation spaces4 (including the classical Sobolev spaces) given by the author5 was directly modeled according to the corresponding atomic characterizations by Frazier and Jawerth,6, 7 more or less with the idea of replacing the dyadic partitions of unity of the Fourier transform side by uniform partitions of unity (so-called BUPU's, first named as such in the early work on Wiener-type spaces by the author in 19808). Watching the literature in the subsequent two decades one can observe that the interest in wavelets "took over", because it became possible to construct orthonormal wavelet systems with compact support and of any given degree of smoothness,9 while in contrast the Balian-Low theorem is prohibiting the existence of corresponding Gabor orthonormal bases, even in the multi-dimensional case and for general symplectic lattices.10 It is an interesting historical fact that* his construction of band-limited orthonormal wavelets (the Meyer wavelet, see11) grew out of an attempt to prove the impossibility of the existence of such systems, and the final insight was that it was not impossible to have such systems, and in fact quite a variety of orthonormal wavelet system can be constructed as we know by now. Meanwhile it is established wisdom that wavelet theory and time-frequency analysis are two different ways of decomposing signals in orthogonal resp. non-orthogonal ways. The unifying theory, covering both cases, distilling from these two situations the common group theoretical background lead to the theory of coorbit spaces,12, 13 established by the author jointly with K. Gröchenig. Starting from an integrable and irreducible representation of some locally compact group (such as the "ax+b"-group or the Heisenberg group) one can derive families of Banach spaces having natural atomic characterizations, or alternatively a continuous transform associated to it. So at the end function spaces of locally compact groups come into play, and their generic properties help to explain why and how it is possible to obtain (nonorthogonal) decompositions. While unification of these two groups was one important aspect of the approach given in the late 80th, it was also clear that this approach allows to formulate and exploit the analogy to Banach spaces of analytic functions invariant under the Moebius group have been at the heart in this context. Recent years have seen further new instances and generalizations. Among them shearlets or the Blaschke product should be mentioned here, and the increased interest in the connections between wavelet theory and complex analysis. The talk will try to summarize a few of the general principles which can be derived from the general theory, but also highlight the difference between the different groups and signal expansions arising from corresponding group representations. There is still a lot more to be done, also from the point of view of applications and the numerical realization of such non-orthogonal expansions.

Small-molecule control of protein function through Staudinger reduction

NASA Astrophysics Data System (ADS)

Luo, Ji; Liu, Qingyang; Morihiro, Kunihiko; Deiters, Alexander

2016-11-01

Using small molecules to control the function of proteins in live cells with complete specificity is highly desirable, but challenging. Here we report a small-molecule switch that can be used to control protein activity. The approach uses a phosphine-mediated Staudinger reduction to activate protein function. Genetic encoding of an ortho-azidobenzyloxycarbonyl amino acid using a pyrrolysyl transfer RNA synthetase/tRNACUA pair in mammalian cells enables the site-specific introduction of a small-molecule-removable protecting group into the protein of interest. Strategic placement of this group renders the protein inactive until deprotection through a bioorthogonal Staudinger reduction delivers the active wild-type protein. This developed methodology was applied to the conditional control of several cellular processes, including bioluminescence (luciferase), fluorescence (enhanced green fluorescent protein), protein translocation (nuclear localization sequence), DNA recombination (Cre) and gene editing (Cas9).

Exploring differences in stakeholders' perceptions of illegal bird trapping in Cyprus.

PubMed

Jenkins, Heather M; Mammides, Christos; Keane, Aidan

2017-11-28

Cyprus is recognised as a hotspot for illegal bird trapping in the Mediterranean basin. A consumer demand for the Eurasian blackcap (Sylvia atricapilla) is driving the use of non-selective trapping methods, resulting in the indiscriminate killing of millions of migratory birds. Efforts to tackle the issue have so far been characterised mostly by a top-down approach, focusing on legislation and enforcement. However, trapping levels are not decreasing and conflict between stakeholder groups is intensifying. To understand why efforts to stop illegal bird trapping have not been effective, we used semi-structured interviews to interview 18 local bird trappers and nine representatives from the pertinent environmental non-governmental organisations (NGOs) and the governmental agencies responsible for enforcing the legislation. We found distinct differences between the views of the local trapping community and the environmental NGOs, particularly on why trapping is occurring and its impact on the avifauna. This disparity has contributed to misrepresentations of both sides and a high degree of conflict, which is potentially proving counterproductive to conservation interventions. In addition, it appears that trappers are a heterogeneous group, likely driven by various motivations besides profit. We argue that stakeholders interested in reducing illegal bird trapping need to develop anti-poaching strategies that aim at minimising the disparity in the views, and subsequently the conflict, acknowledging also that trappers are not a homogenous group, as often treated.

Immigration reform in France and the United States: reflections and documentation.

PubMed

Wenden, C W; Costa-lascoux, J

1984-01-01

This paper analyzes similarities and dissimilarities in French and American efforts to come to grip with irregular migration. The symbolic importance of immigration reform is argued to be a key political concern in both nations, although the politics of immigration reform has assumed a more partisan flavor in France, particularly since the municipal elections of 1983. In France, the theme of control and security, associated with the notion of preventing "automatic" immigration which would endanger the cohesion of French society, was widely utilized for political ends prior to and after May 10, 1981 (the date of Francois Mitterand's investiture). The American government, on the other hand, is confronted with the unenviable task of obtaining a legislative consensus on legalization and employer sanctions through an approach seeking to harmonize and integrate the demands articulated by various groups: employers, unions, and alien and ethnic interest groups (principally Hispanic groups divided into a hierarchy along a recently arrived/established cleavage). The American situation most sharply differs from the French case in terms of the absence of a right/left political cleavage. The real effects of clandestine immigration are to be found at the local level. In France, as in the US, the ability of local actors to exert pressure raises the fear that legalization and sanctions will change little, except in terms of symbolic legitimacy.

On June 17--18, 1998, the Department of Energy`s (DOE) Office of Worker and Community Transition convened its sixth National Stakeholder Workshop at the Ramada Plaza Hotel Old Town in Alexandria, Virginia. Approximately 325 stakeholders attended representing DOE headquarters and field offices, contractors, labor organizations, state and local government, education and community interest groups. The meeting addressed the progress made on the issues and challenges identified at the last stakeholder`s meeting in Oakland, California on April 9--11, 1997. Also discussed were the full range of the Department`s work force issues and creative solutions to the inherent challenges of simultaneously implementing themore » Department`s post Cold-War mission, work force restructuring guidance, contract reform objectives, asset disposition, performance-based management requirements, and business process improvement policies. The format of the Workshop included several plenary sessions and a number of small group discussion sessions. The small group sessions focused on topics related to labor issues, work force restructuring, work force planning, community transition, and employee concerns. The sessions provided a wide range of views on worker and community transition issues. The plenary sessions of the Workshop included presentations on the following topics: welcome and introductions; opening remarks; building a better labor-management relationship; keynote speech from Secretary of Energy Federico Pena; meeting tomorrow`s challenges (early site closures); harnessing the contracting process to encourage local growth; and, the British experience in economic conversion.« less

Chemical composition of sedimentary rocks in California and Hawaii

USGS Publications Warehouse

Hill, Thelma P.

1981-01-01

A compilation of published chemical analyses of sedimentary rocks of the United States was undertaken by the U.S. Geological Survey in 1952 to make available scattered data that are needed for a wide range of economic and scientific uses. About 20,000-25,000 chemical analyses of sedimentary rocks in the United States have been published. This report brings together 2,312 of these analyses from California and Hawaii. The samples are arranged by general lithologic characteristics and locality. Indexes of stratigraphy, rock name, commercial uses, and minor elements are provided. The sedimentary rocks are classified into groups and into categories according to the chemical analyses. The groups (A through F2) are defined by a system similar to that proposed by Brian Mason in 1952, in which the main parameters are the three major components of sedimentary rocks: (1) uncombined silica, (2) clay (R203 ? 3Si02 ? nH20), and (3) calcium-magnesium carbonate. The categories are based on the degree of admixture of these three major components with other components, such as sulfate, phos- phate, and iron oxide. Common-rock, mixed-rock, and special-rock categories apply to rocks consisting of 85 percent or more, 50-84 percent, and less than 49 percent, respectively, of the three major components combined. Maps show distribution of sample localities by States; triangular diagrams show the lithologic characteristics and classification groups. Cumulative-frequency curves of each constituent in each classification group of the common-rock and mixed-rock categories are also included. The numerous analyses may not adequately represent the geochemical nature of the rock types and formations of the region because of sampling bias. Maps showing distribution of sample localities indicate that many of the localities are in areas where, for economic or other reasons, special problems attracted interest. Most of the analyzed rocks tended to be fairly simple in composition - mainly mixtures of just two of the three major components or a mixture of these and a fourth component such as phosphate, gypsum, or iron oxide.

Extracorporeal shock wave lithotripsy of gallstones with oral dissolution. Results in course of ten years in Czech Republic in correlation to indication criteria.

Benes, J; Chmel, J; Blazek, O; Marecek, Z

2001-01-01

We compared the results of treatment of gallbladder stones by extracorporeal shock wave lithotripsy with dissolution during two periods to different criteria of indication. In the first period (1990-1991) we treated patients with stones up to 3 cm in diameter. In the second period (1992-1994) the indication included stones up to 1.5 cm with gallbladder contraction on cholecystography, which was also quantitatively determined by USG exceeding 60% of fasting volume. We used Czech made lithotriptors MEDILIT. The shock waves (SW) are produced by an underwater high voltage discharge and the concentration of SW is achieved by reflection. The localization of stones is performed by means of a sonographic probe. After stone localization usually 700 SW are applied to a patient lying in prone position. Oral dissolution was started in both groups of patients two weeks before shock wave application. Ursodeoxycholic acid and chenodeoxycholic were administered in doses of 7.5 mg/kg body weight/day. In the first group of 260 patients (average age 42), which had moderate indication criteria, disappearance of fragments during one year was found only in 148 (57%). The remaining patients were treated symptomatically or recommended to cholecystectomy. In a second group of 160 patients (average age 45), disappearance of fragments during one year was achieved in 125 (78%). We used stricter indication criteria and our results are much better compared to the first group. Only 208 patients from both groups were controlled for more 5 years, in 89 cases of this number was a recidivity of lithiasis and at 20 of them we indicated cholecystectomy, 22 of the patients refused to continue in the therapy, because the stones are asymptomatic. In our opinion, this therapy (ESWL combined with oral dissolution) is suitable in 7% patients with gallbladder stones. Its side effects are very small, practically negligible. It can be performed without general anaesthesia and on an out-patient basis. After the advent of laparoscopic cholecystectomy we observed diminished interest of both patients and their physicians for gallbladder ESWL, however, after it has reached a widespread use, a new interest in ESWL and dissolution therapy is emerging, which we attribute to its above-mentioned advantages.

Enacting cultural interests: how intergroup contact reduces prejudice by sparking interest in an out-group's culture.

PubMed

Brannon, Tiffany N; Walton, Gregory M

2013-10-01

In the present research, we examined the hypothesis that cues of social connectedness to a member of another social group can spark interest in the group's culture, and that such interest, when freely enacted, contributes to reductions in intergroup prejudice. In two pilot studies and Experiment 1, we found that extant and desired cross-group friendships and cues of social connectedness to an out-group member predicted increased interest in the target group's culture. In Experiments 2 and 3, we manipulated cues of social connectedness between non-Latino American participants and a Latino American (i.e., Mexican American) peer and whether participants freely worked with this peer on a Mexican cultural task. This experience reduced the participants' implicit bias against Latinos, an effect that was mediated by increased cultural engagement, and, 6 months later in an unrelated context, improved intergroup outcomes (e.g., interest in interacting with Mexican Americans; Experiment 4). The Discussion section addresses the inter- and intragroup benefits of policies that encourage people to express and share diverse cultural interests in mainstream settings.

An Agent-Based Simulation for Investigating the Impact of Stereotypes on Task-Oriented Group Formation

NASA Astrophysics Data System (ADS)

Maghami, Mahsa; Sukthankar, Gita

In this paper, we introduce an agent-based simulation for investigating the impact of social factors on the formation and evolution of task-oriented groups. Task-oriented groups are created explicitly to perform a task, and all members derive benefits from task completion. However, even in cases when all group members act in a way that is locally optimal for task completion, social forces that have mild effects on choice of associates can have a measurable impact on task completion performance. In this paper, we show how our simulation can be used to model the impact of stereotypes on group formation. In our simulation, stereotypes are based on observable features, learned from prior experience, and only affect an agent's link formation preferences. Even without assuming stereotypes affect the agents' willingness or ability to complete tasks, the long-term modifications that stereotypes have on the agents' social network impair the agents' ability to form groups with sufficient diversity of skills, as compared to agents who form links randomly. An interesting finding is that this effect holds even in cases where stereotype preference and skill existence are completely uncorrelated.

Cultivating a Network For Messaging About Climate Change Across an Urban System

NASA Astrophysics Data System (ADS)

Wertheim, J.

2014-12-01

Currently, some of the most promising efforts to address climate change are taking place at the scale of cities and municipalities. Large urban areas host an active population of organizations working to influence local environmental policies more rigorous than those at the state and national level. The composition of these groups is broadening as impacts of climate change are being recognized as relevant to more sectors within urban systems, from health centers to community leaders, leading more organizations to consider how they can raise awareness and gain support for their needs. The National Geographic Society, as part of the National Science Foundation (NSF)-funded Climate and Urban Systems Partnership (CUSP), has convened a pilot "community of practice" (CoP) consisting of organizations working at the local level in Washington, DC to communicate with audiences, from the general public to local government agencies, about ways that climate change is predicted to affect the city and what can be done about it. The purpose of the CoP was initially to help these groups coordinate their activities, share knowledge and resources, and to create a platform for ongoing collaborative learning. While the CoP is still evolving, it is clear that it has potential to provide even deeper and more meaningful support to these groups' efforts. Developing effective messaging about climate change across an urban system depends on the valuable insight these groups have into their audience's interests, beliefs, and knowledge, but it also requires a set of competencies that few members of the CoP hold. As conveners of the CoP, we have identified and prioritized those competencies and are developing a process for training CoP members to apply their expertise to implement empirically-based best practices in climate change messaging, public communication, and integration of data and visualizations. The process of training the group has the potential to both create a CoP that becomes a trusted resource for climate messaging activities in DC and an enduring network of professionals who identify participating in the group's ongoing work as essential to their own professional development

Collective Motion in Behaviorally Heterogeneous Systems

NASA Astrophysics Data System (ADS)

Copenhagen, Katherine

Collective motion is a widespread phenomenon in nature where individuals actively propel themselves, gather together and move as a group. Some examples of collective motion are bird flocks, fish schools, bacteria swarms, cell clusters, and crowds of people. Many models seek to understand the effects of activity in collective systems including things such as environmental disorder, density, and interaction details primarily at infinite size limits and with uniform populations. In this dissertation I investigate the effects of finite sizes and behavioral heterogeneity as it exists in nature. Behavioral heterogeneity can originate from several different sources. Mixed populations of individuals can have inherently different behaviors such as mutant bacteria, injured fish, or agents that prefer individualistic behavior over coordinated motion. Alternatively, agents may modify their own behavior based on some local environmental dependency, such as local substrate, or density. In cases such as mutant cheaters in bacteria or malfunctioning drones in swarms, mixed populations of behaviorally heterogeneous agents can be modelled as arising in the form of aligning and non-aligning agents. When this kind of heterogeneity is introduced, there is a critical carrying capacity of non-aligners above which the system is unable to form a cohesive ordered group. However, if the cohesion of the group is relaxed to allow for fracture, the system will actively sort out non-aligning agents the system will exist at a critical non-aligner fraction. A similar heterogeneity could result in a mixture of high and low noise individuals. In this case there is also a critical carry capacity beyond which the system is unable to reach an ordered state, however the nature of this transition depends on the model details. Agents which are part of an ordered collective may vary their behavior as the group changes environments such as a flock of birds flying into a cloud. Using a unique model of a flock where the group behaves as a rigid disk reveals interesting behaviors as the system crosses a boundary between interfaces. The collective rotates and reorients or becomes stuck on the boundary as it crosses. I also investigate the effects of variable behavior depending on local density, and find that a frustration driven transient rotational phase arises in clusters where agents with low local density move faster than those with high local density as in cell clusters. All together I have shown that behavioral heterogeneity in collective motion can lead to unique phases and behaviors that are not seen in their homogeneous counterparts.

Negotiation techniques to resolve western water disputes

USGS Publications Warehouse

Lamb, Berton L.; Taylor, Jonathan G.

1990-01-01

There is a growing literature on the resolution of natural resources conflicts. Much of it is practical, focusing on guidelines for hands-on negotiation. This literature can be a guide in water conflicts. This is especially true for negotiations over new environmental values such as instream flow. The concepts of competitive, cooperative, and integrative styles of conflict resolution are applied to three cases of water resource bargaining. Lessons for the effective use of these ideas include: break a large number of parties into small working groups, approach value differences in small steps, be cautious in the presence of an attentive public, keeps decisions at the local level, and understand the opponent's interests.

We derive the invariant measure on the manifold of multimode quantum Gaussian states, induced by the Haar measure on the group of Gaussian unitary transformations. To this end, by introducing a bipartition of the system in two disjoint subsystems, we use a parameterization highlighting the role of nonlocal degrees of freedom—the symplectic eigenvalues—which characterize quantum entanglement across the given bipartition. A finite measure is then obtained by imposing a physically motivated energy constraint. By averaging over the local degrees of freedom we finally derive the invariant distribution of the symplectic eigenvalues in some cases of particular interest for applications in quantum optics and quantum information.

Mapping approaches offer great potential for community-based participatory researchers interested in displaying youth perceptions and advocating for change. We describe a multi-layered approach for gaining local knowledge of neighborhood environments that engages youth as co-researchers and active knowledge producers. By integrating geographic information systems (GIS) with environmental audits, an interactive focus group, and sketch mapping, the approach provides a place-based understanding of physical activity resources from the situated experience of youth. Youth report safety and a lack of recreational resources as inhibiting physical activity. Maps reflecting youth perceptions aid policy-makers in making place-based improvements for youth neighborhood environments. PMID:25423245

Localized waves in three-component coupled nonlinear Schrödinger equation

2016-09-01

We study the generalized Darboux transformation to the three-component coupled nonlinear Schrödinger equation. First- and second-order localized waves are obtained by this technique. In first-order localized wave, we get the interactional solutions between first-order rogue wave and one-dark, one-bright soliton respectively. Meanwhile, the interactional solutions between one-breather and first-order rogue wave are also given. In second-order localized wave, one-dark-one-bright soliton together with second-order rogue wave is presented in the first component, and two-bright soliton together with second-order rogue wave are gained respectively in the other two components. Besides, we observe second-order rogue wave together with one-breather in three components. Moreover, by increasing the absolute values of two free parameters, the nonlinear waves merge with each other distinctly. These results further reveal the interesting dynamic structures of localized waves in the three-component coupled system.

In the early 1990s, St. Louis County had multiple foodservice worker-related hepatitis A outbreaks uncontrolled by standard outbreak interventions. Restaurant interest groups and the general public applied political pressure to local public health officials for more stringent interventions, including a mandatory vaccination policy. Local health departments can enact mandatory vaccination policies, but this has rarely been done. The study objectives were to describe the approach used to pass a mandatory vaccination policy at the local jurisdiction level and illustrate the outcome from this ordinance 15 years later. A case study design was used. In-depth, semi-structured interviews using guided questions were conducted in spring, 2015, with six key informants who had direct knowledge of the mandatory vaccination policy process. Meeting minutes and/or reports were also analyzed. A Poisson distribution analysis was used to calculate the rate of outbreaks before and after mandatory vaccination policy implementation. The policy appears to have reduced the number of hepatitis A outbreaks, lowering the morbidity and economic burden in St. Louis County. The lessons learned by local public health officials in passing a mandatory hepatitis A vaccination policy are important and relevant in today's environment. The experience and lessons learned may assist other local health departments when faced with the potential need for mandatory policies for any vaccine preventable disease.

Conservative surgery can be regarded as the standard treatment for most early stage breast tumors. However, a minority of patients treated with conservative surgery will present local or locoregional recurrence. Therefore, it is of interest to evaluate the possible factors associated with this recurrence. A population-based retrospective study using data from the Tumor Registry of Castellón (Valencia, Spain) of patients operated on for primary nonmetastatic breast cancer between January 2000 and December 2008 was designed. Kaplan-Meier curves and log-rank test to estimate 5-year local recurrence were used. Two groups of patients were defined, one with conservative surgery and another with nonconservative surgery. Cox multivariate analysis was conducted. The total number of patients was 410. Average local recurrence was 6.8%. In univariate analysis, only tumor size and lymph node involvement showed significant differences. On multivariate analysis, independent prognostic factors were conservative surgery (hazard ratio [HR] 4.62; 95% confidence interval [CI]: 1.12-16.82), number of positive lymph nodes (HR 1.07; 95% CI: 1.01-1.17) and tumor size (in mm) (HR 1.02; 95% CI: 1.01-1.06). Local recurrence after breast-conserving surgery is higher in tumors >2 cm. Although tumor size should not be a contraindication for conservative surgery, it should be a risk factor to be considered.

Fusion-based multi-target tracking and localization for intelligent surveillance systems

Rababaah, Haroun; Shirkhodaie, Amir

2008-04-01

In this paper, we have presented two approaches addressing visual target tracking and localization in complex urban environment. The two techniques presented in this paper are: fusion-based multi-target visual tracking, and multi-target localization via camera calibration. For multi-target tracking, the data fusion concepts of hypothesis generation/evaluation/selection, target-to-target registration, and association are employed. An association matrix is implemented using RGB histograms for associated tracking of multi-targets of interests. Motion segmentation of targets of interest (TOI) from the background was achieved by a Gaussian Mixture Model. Foreground segmentation, on other hand, was achieved by the Connected Components Analysis (CCA) technique. The tracking of individual targets was estimated by fusing two sources of information, the centroid with the spatial gating, and the RGB histogram association matrix. The localization problem is addressed through an effective camera calibration technique using edge modeling for grid mapping (EMGM). A two-stage image pixel to world coordinates mapping technique is introduced that performs coarse and fine location estimation of moving TOIs. In coarse estimation, an approximate neighborhood of the target position is estimated based on nearest 4-neighbor method, and in fine estimation, we use Euclidean interpolation to localize the position within the estimated four neighbors. Both techniques were tested and shown reliable results for tracking and localization of Targets of interests in complex urban environment.

Interest Rate Demands and Television Viewing-Is a Single Exposure More Influential Than Routine Viewing?

This study examined the impact of media consumption, and particularly exposure to television, on decisions regarding interest rate demands. One hundred and fifty-four participants were randomly divided into two groups: in the manipulation group, participants were exposed to a news clip about an Iranian nuclear attack on Israel, whereas in the control group, the participants were not exposed to the film. Both groups filled a questionnaires regarding their interest rate requirements in different situations, their media conception behaviors, and demographic questionnaires. Frequent routine viewing increased the interest rate demands only among participants in the manipulation group, but the manipulation itself did not have a significant effect on interest rate demands. The results are explained in terms of cultivation theory.

How Clean is your Local Air? Here's an app for that

Air quality is a vital element of our environment. Accurate and localized air quality information is critical for characterizing environmental impacts at the local and regional levels. Advances in location-aware handheld devices and air quality modeling have enabled a group of UAHuntsville scientists to develop a mobile app, LocalAQI, that informs users of current conditions and forecasts of up to twenty-four hours, of air quality indices. The air quality index is based on Community Multiscale Air Quality Modeling System (CMAQ). UAHuntsville scientists have used satellite remote sensing products as inputs to CMAQ, resulting in forecast guidance for particulate matter air quality. The CMAQ output is processed to compute a standardized air quality index. Currently, the air quality index is available for the eastern half of the United States. LocalAQI consists of two main views: air quality index view and map view. The air quality index view displays current air quality for the zip code of a location of interest. Air quality index value is translated into a color-coded advisory system. In addition, users are able to cycle through available hourly forecasts for a location. This location-aware app defaults to the current air quality of user's location. The map view displays color-coded air quality information for the eastern US with an ability to animate through the available forecasts. The app is developed using a cross-platform native application development tool, appcelerator; hence LocalAQI is available for iOS and Android-based phones and pads.

Local Dynamics of Acid- and Ion-containing Copolymer Melts

Winey, Karen; Middleton, Robert; Tarver, Jacob; Tyagi, Madhusudan; Soles, Christopher; Frischknecht, Amalie

Interest in acid- and ion-containing polymers arises in part from applications as single-ion conductors for selectively transporting a counter ion for battery applications. Structurally, the low dielectric constant of organic polymers and strong ionic interactions leads to ionic aggregation. Here the polymer backbone motion was investigated through quasi-elastic neutron scattering measurements (QENS) and compared with fully atomistic molecular dynamic simulations of precise poly(ethylene-acrylic acid) copolymers and their ionomers (pxAA-y%Li). The effect of carbon spacer length (x =9, 15, 21) between the acid groups and the degree of neutralization (y) with Li on PE backbone dynamics were considered. Systematic slowing in chain dynamics were observed with increasing neutralization where polymer dynamics appear constrained due to anchoring effects. Simulations provide complementary viewpoints indicating a gradient in chain dynamics as a distance away from acid groups. These results indicate that the addition of pendant acid groups inhibit typical PE backbone motion and the neutralized forms strongly suppress the fraction of mobile PE chain.

PROBLEM ADDRESSED The need for effective and accessible educational approaches by which family physicians can maintain practice competence in the face of an overwhelming amount of medical information. OBJECTIVE OF PROGRAM The practice-based small group (PBSG) learning program encourages practice changes through a process of small-group peer discussion—identifying practice gaps and reviewing clinical approaches in light of evidence. PROGRAM DESCRIPTION The PBSG uses an interactive educational approach to continuing professional development. In small, self-formed groups within their local communities, family physicians discuss clinical topics using prepared modules that provide sample patient cases and accompanying information that distils the best evidence. Participants are guided by peer facilitators to reflect on the discussion and commit to appropriate practice changes. CONCLUSION The PBSG has evolved over the past 15 years in response to feedback from members and reflections of the developers. The success of the program is evidenced in effect on clinical practice, a large and increasing number of members, and the growth of interest internationally. PMID:17872876

Link-prediction to tackle the boundary specification problem in social network surveys

De Wilde, Philippe; Buarque de Lima-Neto, Fernando

2017-01-01

Diffusion processes in social networks often cause the emergence of global phenomena from individual behavior within a society. The study of those global phenomena and the simulation of those diffusion processes frequently require a good model of the global network. However, survey data and data from online sources are often restricted to single social groups or features, such as age groups, single schools, companies, or interest groups. Hence, a modeling approach is required that extrapolates the locally restricted data to a global network model. We tackle this Missing Data Problem using Link-Prediction techniques from social network research, network generation techniques from the area of Social Simulation, as well as a combination of both. We found that techniques employing less information may be more adequate to solve this problem, especially when data granularity is an issue. We validated the network models created with our techniques on a number of real-world networks, investigating degree distributions as well as the likelihood of links given the geographical distance between two nodes.

Lethal coalitionary aggression and long-term alliance formation among Yanomamö men.

Some cross-cultural evidence suggests lethal coalitionary aggression in humans is the product of residence and descent rules that promote fraternal interest groups, i.e., power groups of coresident males bonded by kinship. As such, human lethal coalitions are hypothesized to be homologous to chimpanzee (Pan troglodytes) border patrols. However, humans demonstrate a unique metagroup social structure in which strategic alliances allow individuals to form coalitions transcending local community boundaries. We test predictions derived from the fraternal interest group and strategic alliance models using lethal coalition data from a lowland South American population, the Yanomamö. Yanomamö men who kill an enemy acquire a special status, termed unokai. We examine the social characteristics of co-unokais or men who jointly kill others. Analyses indicate co-unokais generally are (i) from the same population but from different villages and patrilines, (ii) close age mates, and (iii) maternal half-first cousins. Furthermore, the incident rate for co-unokai killings increases if men are similar in age, from the same population, and from different natal communities. Co-unokais who have killed more times in the past and who are more genetically related to each other have a higher probability of coresidence in adulthood. Last, a relationship exists between lethal coalition formation and marriage exchange. In this population, internal warfare unites multiple communities, and co-unokais strategically form new residential groups and marriage alliances. These results support the strategic alliance model of coalitionary aggression, demonstrate the complexities of human alliance formation, and illuminate key differences in social structure distinguishing humans from other primates.

There is little guidance regarding how to disclose researchers' financial interests to potential research participants. To determine what potential research participants want to know about financial interests, their capacity to understand disclosed information and its implications, and the reactions of potential research participants to a proposed disclosure statement. Sixteen focus groups in 3 cities, including 6 groups of healthy adults, 6 groups of adults with mild chronic illness, 1 group of parents of healthy children, 1 group of parents of children with leukemia or brain tumor, 1 group of adults with heart failure, and 1 group of adults with cancer. Focus group discussions covered a range of topics including financial relationships in clinical research, whether people should be told about them, and how they should be told. Audio-recordings of focus groups were transcribed, verified, and coded for analysis. Participants wanted to know about financial interests, whether or not those interests would affect their participation. However, they varied in their desire and ability to understand the nature and implications of financial interests. Whether disclosure was deemed important depended upon the risk of the research. Trust in clinicians was also related to views regarding disclosure. If given the opportunity to ask questions during the consent process, some participants would not have known what to ask; however, after the focus group sessions, participants could identify information they would want to know. Financial interests are important to potential research participants, but obstacles to effective disclosure exist.

Future nuclear steam supply systems (NSSSs) will be designed in an environment of powerful micro hardware and software and these systems will be linked by local area networks (LAN). With such systems, individual NSSS designers and design groups will establish and maintain local data bases to replace existing manual files and data sources. One such effort of this type in Combustion Engineering's (C-E's) NSSS engineering organization is the establishment of a data base of historical manufacturing, installation, and operating experience to provide designers with information to improve on current designs and practices. In contrast to large mainframe or minicomputer datamore » bases, which compile industry-wide data, the data base described here is implemented on a microcomputer, is design specific, and contains a level of detail that is of interest to system and component designers. DBASE III, a popular microcomputer data base management software package, is used. In addition to the immediate benefits provided by the data base, the development itself provided a vehicle for identifying procedural and control aspects that need to be addressed in the environment of local microcomputer data bases. This paper describes the data base and provides some observations on the development, use, and control of local microcomputer data bases in a design organization.« less

Human tuberculosis (TB) principally involves the lungs, where local immunity impacts on the load of Mycobacterium tuberculosis (M.tb). Because concomitants of local Th1 immunity are still under-explored in humans, we characterized immune responses in bronchoalveolar cells (BACs) and systemically in peripheral blood mononuclear cells (PBMCs) in persons with active pulmonary TB and in healthy community controls. PPD- and live M.tb-induced IFN-gamma-production were observed in CD4(+), CD8(+), gammadeltaTCR(+), and CD56(+) alveolar T cell subpopulations and NK cells (CD3(-)CD56(+)). IFN-gamma-producing CD4(+) T cells (mostly CD45RO(+)) were more abundant (p<0.05). M.tb-induced IL-12p70, but interestingly also IL-4, was increased (p<0.05) in BACs from TB patients. Constitutive expression of IL-12Rbeta1 and IL-12Rbeta2 mRNA in BACs and PBMCs and IFN-gammaR1 in BACs was similar in both study groups. Data were normalized to account for differences in proportions of alveolar T cells and macrophages in the study groups. IFN-gamma-production and its induction by IL-12R engagement occur virtually unimpaired in the bronchoalveolar spaces of patients with pulmonary TB. The reasons for the apparent failure to control M. tuberculosis growth during active pulmonary TB disease is unknown but could be the expression of locally acting immunosuppressive mechanisms that subvert the antimycobacterial effects of IFN-gamma.

Trichotillomania (hair-pulling disorder) is characterized by the repetitive pulling out of one's own hair, and is classified as an Obsessive-Compulsive Related Disorder. Abnormalities of the ventral and dorsal striatum have been implicated in disease models of trichotillomania, based on translational research, but direct evidence is lacking. The aim of this study was to elucidate subcortical morphometric abnormalities, including localized curvature changes, in trichotillomania. De-identified MRI scans were pooled by contacting authors of previous peer-reviewed studies that examined brain structure in adult patients with trichotillomania, following an extensive literature search. Group differences on subcortical volumes of interest were explored (t-tests) and localized differences in subcortical structure morphology were quantified using permutation testing. The pooled sample comprised N=68 individuals with trichotillomania and N=41 healthy controls. Groups were well-matched in terms of age, gender, and educational levels. Significant volumetric reductions were found in trichotillomania patients versus controls in right amygdala and left putamen. Localized shape deformities were found in bilateral nucleus accumbens, bilateral amygdala, right caudate and right putamen. Structural abnormalities of subcortical regions involved in affect regulation, inhibitory control, and habit generation, play a key role in the pathophysiology of trichotillomania. Trichotillomania may constitute a useful model through which to better understand other compulsive symptoms. These findings may account for why certain medications appear effective for trichotillomania, namely those modulating subcortical dopamine and glutamatergic function. Future work should study the state versus trait nature of these changes, and the impact of treatment.

To obtain a thorough understanding of the complexity and dynamics of the social determination of HIV infection among inhabitants of Cartagena, Colombia, as well as their views on necessary actions and priorities. In a five-year ethnography of HIV/AIDS in collaboration with 96 citizens of Cartagena, different methods and data collection techniques were used. Through 40 in-depth interviews and 30 life histories of inhabitants, the scenario of HIV vulnerability was summarized in a diagram. This diagram was evaluated and complemented through group discussions with key representatives of local governmental and nongovernmental organizations and with people who were interested in the epidemic or affected by it. The diagram illustrates the dynamic and complex interrelationships among structural factors (i.e., social determinants) of HIV infection, such as machismo; lack of work, money, and social services; local dynamics of the performance of the state; and international dynamics of the sexual tourism industry. On the basis of the diagram, groups of key representatives proposed prioritizing structural actions such as reducing socioeconomic inequalities and providing access to health care and education. The social determinants displayed in the diagram relate to historic power forces that have shaped vulnerable scenarios in Cartagena. Collaboration between participants and researchers generates conceptual frameworks that make it possible to understand and manage the complexity of HIV's social determination. This way of understanding effectively connects local inequalities with international flows of power such as sexual tourism and makes evident the strengths and limitations of current approaches to HIV prevention.

Associating attributes to pedestrians in a crowd is relevant for various areas like surveillance, customer profiling and service providing. The attributes of interest greatly depend on the application domain and might involve such social relations as friends or family as well as the hierarchy of the group including the leader or subordinates. Nevertheless, the complex social setting inherently complicates this task. We attack this problem by exploiting the small group structures in the crowd. The relations among individuals and their peers within a social group are reliable indicators of social attributes. To that end, this paper identifies social groups based on explicit motion models integrated through a hypothesis testing scheme. We develop two models relating positional and directional relations. A pair of pedestrians is identified as belonging to the same group or not by utilizing the two models in parallel, which defines a compound hypothesis testing scheme. By testing the proposed approach on three datasets with different environmental properties and group characteristics, it is demonstrated that we achieve an identification accuracy of 87% to 99%. The contribution of this study lies in its definition of positional and directional relation models, its description of compound evaluations, and the resolution of ambiguities with our proposed uncertainty measure based on the local and global indicators of group relation.

The identity and history of the indigenous groups who occupied the Lesser Antilles during the ceramic periods remain highly controversial. Although recent archaeological evidence has challenged hypotheses concerning the organization of human groups in this region, more biological data are needed to fully inform the discussion. Our study provides, to our knowledge, the first palaeogenetic data for Late Ceramic groups of the Guadeloupe archipelago, yielding crucial information concerning the identities of these groups. Despite the generally poor DNA preservation in the tested remains, we were able to retrieve Hypervariable Region 1 sequences from 11 individuals and mitochondrial single-nucleotide polymorphisms from 13 individuals. These novel data provide interesting preliminary results in favour of a common origin for all Saladoid Caribbean communities, i.e. the first ceramic groups of the region, as well as for a local continuity between the Saladoid and post-Saladoid groups. A combination of the genetic data obtained and several pieces of cultural evidence allows us to propose that two different groups inhabited the Guadeloupe archipelago during the Late Ceramic period, with the possible occupation of the La Désirade and Marie-Galante islands by groups affiliated with the Taíno communities. The working hypotheses proposed here appear consistent with recent archaeological evidence. PMID:25487339

Recent spectroscopic studies have revealed the appearance of multiple low-energy peaks in the fluorescence of single-walled carbon nanotubes (SWCNTs) upon their covalent functionalization by aryl groups. The photophysical nature of these low energy optical bands is of significant interest in the quest to understand their appearance and to achieve their precise control via chemical modification of SWCNTs. This theoretical study explains the specific energy dependence of emission features introduced in chemically functionalized (6,5) SWCNTs with aryl bromides at different conformations and in various dielectric media. Calculations using density functional theory (DFT) and time dependent DFT (TD-DFT) show that the specificmore » isomer geometry—the relative position of functional groups on the carbon-ring of the nanotube—is critical for controlling the energies and intensities of optical transitions introduced by functionalization, while the dielectric environment and the chemical composition of functional groups play less significant roles. Furthermore, the predominant effects on optical properties as a result of functionalization conformation are rationalized by exciton localization on the surface of the SWCNT near the dopant sp3-defect but not onto the functional group itself.« less

Boric acid (BA) has positive effects on bone tissue. In this study, the effects of BA on fracture healing were evaluated in an animal model. Standard closed femoral shaft fractures were created in 40 male Sprague-Dawley rats under general anesthesia. The rats were allocated into five groups (n = 8 each): group 1, control with no BA; groups 2 and 3, oral BA at doses of 4 and 8 mg/kg/day, respectively; group 4, local BA (8 mg/kg); and group 5, both oral and local BA (8 mg/kg/day orally and 8 mg/kg locally). After closed fracture creation, the fracture line was opened with a mini-incision, and BA was locally administered to the fracture area in groups 4 and 5. In groups 2, 3, and 5, BA was administered by gastric gavage daily until sacrifice. The rats were evaluated by clinical, radiological, and histological examinations. The control group (group 1) significantly differed from the local BA-exposed groups (groups 4 and 5) in the clinical evaluation. Front-rear and lateral radiographs revealed significant differences between the local BA-exposed groups and the control and other groups (p < 0.05). Clinical and radiological evaluations demonstrated adequate agreement between observers. The average histological scores significantly differed across groups (p = 0.007) and were significantly higher in groups 4 and 5 which were the local BA (8 mg/kg) and both oral and local BA (8 mg/kg/day orally and 8 mg/kg locally), respectively, compared to the controls. This study suggests that BA may be useful in fracture healing. Further research is required to demonstrate the most effective local dosage and possible use of BA-coated implants.

Biclustering as a method for RNA local multiple sequence alignment.

Biclustering is a clustering method that simultaneously clusters both the domain and range of a relation. A challenge in multiple sequence alignment (MSA) is that the alignment of sequences is often intended to reveal groups of conserved functional subsequences. Simultaneously, the grouping of the sequences can impact the alignment; precisely the kind of dual situation biclustering is intended to address. We define a representation of the MSA problem enabling the application of biclustering algorithms. We develop a computer program for local MSA, BlockMSA, that combines biclustering with divide-and-conquer. BlockMSA simultaneously finds groups of similar sequences and locally aligns subsequences within them. Further alignment is accomplished by dividing both the set of sequences and their contents. The net result is both a multiple sequence alignment and a hierarchical clustering of the sequences. BlockMSA was tested on the subsets of the BRAliBase 2.1 benchmark suite that display high variability and on an extension to that suite to larger problem sizes. Also, alignments were evaluated of two large datasets of current biological interest, T box sequences and Group IC1 Introns. The results were compared with alignments computed by ClustalW, MAFFT, MUCLE and PROBCONS alignment programs using Sum of Pairs (SPS) and Consensus Count. Results for the benchmark suite are sensitive to problem size. On problems of 15 or greater sequences, BlockMSA is consistently the best. On none of the problems in the test suite are there appreciable differences in scores among BlockMSA, MAFFT and PROBCONS. On the T box sequences, BlockMSA does the most faithful job of reproducing known annotations. MAFFT and PROBCONS do not. On the Intron sequences, BlockMSA, MAFFT and MUSCLE are comparable at identifying conserved regions. BlockMSA is implemented in Java.

This study examines the effect of history-based instruction on the topic of the atom on students' academic achievement and their interest in the history of science, investigating as well the relationship between student interest and academic achievement. The sample of the study consisted of two groups of freshman students from an undergraduate elementary science teachers program. The same chemistry instructor taught the groups, which were randomly assigned as an experimental and a control group. The students in the control group received traditional teacher-centered instruction, while the experimental group students were taught the topic of the atom using history-based instruction enriched with various sources of situational interest such as novelty, autonomy, social involvement, and knowledge acquisition (NASK). Data gathering instruments were the Atom Achievement Test and the History of Science Interest Scale, administered to both of the groups before and after the instruction. The data were analyzed with the independent-samples t test, the paired-samples t test, and one-way ANCOVA statistical analysis. The results showed that the history-based instruction including NASK was more effective than traditional instruction in improving the students' learning of the subject of the atom as well as in stimulating and improving students' interest in the history of science. Further, students with high interest displayed significantly better achievement than students with low interest. The better learning of the topic of the atom was more pronounced in the case of students with a high interest in the history of science compared to students with moderate or low interest.

Indonesia's road to universal health coverage: a political journey.

In 2013 Indonesia, the world's fourth most populous country, declared that it would provide affordable health care for all its citizens within seven years. This crystallised an ambition first enshrined in law over five decades earlier, but never previously realised. This paper explores Indonesia's journey towards universal health coverage (UHC) from independence to the launch of a comprehensive health insurance scheme in January 2014. We find that Indonesia's path has been determined largely by domestic political concerns – different groups obtained access to healthcare as their socio-political importance grew. A major inflection point occurred following the Asian financial crisis of 1997. To stave off social unrest, the government provided health coverage for the poor for the first time, creating a path dependency that influenced later policy choices. The end of this programme coincided with decentralisation, leading to experimentation with several different models of health provision at the local level. When direct elections for local leaders were introduced in 2005, popular health schemes led to success at the polls. UHC became an electoral asset, moving up the political agenda. It also became contested, with national policy-makers appropriating health insurance programmes that were first developed locally, and taking credit for them. The Indonesian experience underlines the value of policy experimentation, and of a close understanding of the contextual and political factors that drive successful UHC models at the local level. Specific drivers of success and failure should be taken into account when scaling UHC to the national level. In the Indonesian example, UHC became possible when the interests of politically and economically influential groups were either satisfied or neutralised. While technical considerations took a back seat to political priorities in developing the structures for health coverage nationally, they will have to be addressed going forward to achieve sustainable UHC in Indonesia.

Guarding against land-expropriation-related mass incidents (LERMIs): Practical evidence from China's local governments

China is faced with serious challenges brought by large-scale social protests in the period of rapid urbanization and profound social transition. In rural areas, the vast majority of mass incidents were related with land expropriation. In this paper, we intend to show how China's local governments guard against land-expropriation-related mass incidents (LERMIs) at the practical level. We first construct a comprehensive three-dimensional theoretic framework to define the boundary, to uncover the incentives, and to recognize the features of involved practices, then, on the basis of description evidenced by detailed data and/or cases, break various local practices down into two categories, the common local practices which refer to the nationwide top-down responses to the unified deployment by the central authority that aims to mitigate discontentment of land-deprived peasants and reduce the probabilities of conflicts through regulating land expropriation behavior and safeguarding economic interests and participation rights of affected peasants, and the specific local practices which point to the innovative local government behaviors with heterogeneity, in general, the tactical approaches to reduce the probabilities of disputes or conflicts evolving into group actions. We further argue that both of them follow a central tenet of instrumental orientation. As to the former, it is corroborated by local governments' paying more attention to promote the stylization and quantification in the aspects of regulating procedure, formulating and renewing compensation standards, resolving disputes, and evaluating risks, while the latter is mainly reflected from the outcome-orientation organization strategies to maintain overall stability in a relatively short term.

Simultaneous measurement of cerebral blood flow and mRNA signals: pixel-based inter-modality correlational analysis.

The analysis of pixel-based relationships between local cerebral blood flow (LCBF) and mRNA expression can reveal important insights into brain function. Traditionally, LCBF and in situ hybridization studies for genes of interest have been analyzed in separate series. To overcome this limitation and to increase the power of statistical analysis, this study focused on developing a double-label method to measure local cerebral blood flow (LCBF) and gene expressions simultaneously by means of a dual-autoradiography procedure. A 14C-iodoantipyrine autoradiographic LCBF study was first performed. Serial brain sections (12 in this study) were obtained at multiple coronal levels and were processed in the conventional manner to yield quantitative LCBF images. Two replicate sections at each bregma level were then used for in situ hybridization. To eliminate the 14C-iodoantipyrine from these sections, a chloroform-washout procedure was first performed. The sections were then processed for in situ hybridization autoradiography for the probes of interest. This method was tested in Wistar rats subjected to 12 min of global forebrain ischemia by two-vessel occlusion plus hypotension, followed by 2 or 6 h of reperfusion (n=4-6 per group). LCBF and in situ hybridization images for heat shock protein 70 (HSP70) were generated for each rat, aligned by disparity analysis, and analyzed on a pixel-by-pixel basis. This method yielded detailed inter-modality correlation between LCBF and HSP70 mRNA expressions. The advantages of this method include reducing the number of experimental animals by one-half; and providing accurate pixel-based correlations between different modalities in the same animals, thus enabling paired statistical analyses. This method can be extended to permit correlation of LCBF with the expression of multiple genes of interest.

Poor balance control and increased fall risk have been reported in people with diabetic peripheral neuropathy (DPN). Traditional body sway measures are unable to describe underlying postural control mechanism. In the current study, we used stabilogram diffusion analysis to examine the mechanism under which balance is altered in DPN patients under local-control (postural muscle control) and central-control (postural control using sensory cueing). DPN patients and healthy age-matched adults over 55 years performed two 15-second Romberg balance trials. Center of gravity sway was measured using a motion tracker system based on wearable inertial sensors, and used to derive body sway and local/central control balance parameters. Eighteen DPN patients (age = 65.4±7.6 years; BMI = 29.3±5.3 kg/m2) and 18 age-matched healthy controls (age = 69.8±2.9; BMI = 27.0±4.1 kg/m2) with no major mobility disorder were recruited. The rate of sway within local-control was significantly higher in the DPN group by 49% (healthy local-controlslope = 1.23±1.06×10-2 cm2/sec, P<0.01), which suggests a compromised local-control balance behavior in DPN patients. Unlike local-control, the rate of sway within central-control was 60% smaller in the DPN group (healthy central-controlslope-Log = 0.39±0.23, P<0.02), which suggests an adaptation mechanism to reduce the overall body sway in DPN patients. Interestingly, significant negative correlations were observed between central-control rate of sway with neuropathy severity (rPearson = 0.65-085, P<0.05) and the history of diabetes (rPearson = 0.58-071, P<0.05). Results suggest that in the lack of sensory feedback cueing, DPN participants were highly unstable compared to controls. However, as soon as they perceived the magnitude of sway using sensory feedback, they chose a high rigid postural control strategy, probably due to high concerns for fall, which may increase the energy cost during extended period of standing; the adaptation mechanism using sensory feedback depends on the level of neuropathy and the history of diabetes.

Systematic Review and Meta-Analysis OBJECTIVE.: To identify whether intramuscular local anesthetic infiltration prior to wound closure was effective in reducing postoperative pain and facilitating early discharge following lumbar spine surgery. Local anesthetic infiltration prior to wound closure may form part of the multimodal strategy for postoperative analgesia, facilitating early mobilization and discharge. Although there are a number of small studies investigating its utility, a quantitative meta-analysis of the data has never been performed. This review was conducted according the PRISMA statement and was registered with the PROSPERO database. Only randomized controlled trials were eligible for inclusion. Key outcomes of interest included time to first analgesic demand, total postoperative opiate usage in the first 24 hours, visual analogue score (VAS) at 1, 12 and 24 hours and postoperative length of stay. Eleven publications fulfilled the inclusion criteria. A total of 438 patients were include; 212 in the control group and 226 in the intervention group. Local anesthetic infiltration resulted in a prolonged time to first analgesic demand (mean difference (MD) 65.88 minutes, 95% confidence interval (95% CI) 23.70 to 108.06, P.0.002) as well as a significantly reduced postoperative opiate demand (M.D. -9.71 mg, 95% CI -15.07, -4.34, p = 0.0004). There was a small but statistically significant reduction in postoperative visual analogue score (VAS) at 1 hour (M.D. -0.87 95%CI -1.55, -0.20, p = 0.01), but no significant reduction at 12 or 24 hours (p = 0.93 and 0.85 respectively). This systematic review and meta-analysis provides evidence that postoperative intramuscular local anaesthetic infiltration reduces postoperative analgesic requirements and the time to first analgesic demands for patients undergoing lumbar spine surgery. Key research priorities include optimization of the choice and strength of local anaesthetic agent and health-economic analyses to strengthen the case for routine use of postoperative local anesthetics in lumbar spine surgery. 1.

Civil society (CS) strengthening is central to peacebuilding policies for divided, post-war societies. However, it has been criticized for creating internationalized organizations without local backing, unable to represent citizens’ interests. Based on in-depth empirical research in Bosnia-Herzegovina, this article focuses on the legitimacy of CS organizations (CSOs). It explores why legitimacy for donors rarely accompanies legitimacy for local actors. We hypothesized that whilst donors avoid supporting mono-ethnic organizations, seen as problematic for peacebuilding, ‘ethnicness’ may provide local legitimacy. However, our analysis of CSOs’ ethnicness nuances research characterizing organizations as either inclusive or divisive. Moreover, local legitimacy is not based on ethnicness per se, but CSOs’ ability to skilfully interact with ethnically divided constituencies and political structures. In addition, we offer novel explanations why few organizations enjoy both donor and local legitimacy, including local mistrust of donors’ normative frameworks and perceived lack of results. However, we also show that a combination of local and donor legitimacy is possible, and explore this rare but interesting category of organizations. PMID:28546640

2013-01-01

The capacity for subjects to learn to volitionally control localized brain activity using neurofeedback is actively being investigated. We aimed to investigate the ability of healthy volunteers to quickly learn to use visual feedback during real-time functional MRI (rtfMRI) to modulate brain activity within their anterior right insular cortex (RIC) localized during a blink suppression task, an approach of possible interest in the use of rtfMRI to reduce urges. The RIC region of interest (RIC-ROI) was functionally localized using a blink suppression task, and blood-oxygen level dependent (BOLD) signal changes within RIC-ROI used to create a constantly updating display fed back to the subject in the scanner. Subjects were instructed to use emotional imagery to try and increase activity within RIC-ROI during four feedback training runs (FB1-FB4). A "control" run (CNTRL) before training and a "transfer" run (XSFR) after training were performed without feedback to assess for baseline abilities and learning effects. Fourteen participants completed all neurofeedback training runs. At the group-level, increased BOLD activity was seen in the anterior RIC during all the FB runs, but a significant increase in the functionally defined RIC-ROI was only attained during FB2. In atlas-defined insular cortex ROIs, significant increases were seen bilaterally during the CNTRL, FB1, FB2, and FB4 runs. Increased activity within the insular cortices did not show lateralization. Training did, however, result in a significant increase in functional connectivity between the RIC-ROI and the medial frontal gyrus when comparing FB4 to FB1. Since neurofeedback training did not lead to an increase in BOLD signal across all feedback runs, we suggest that learning to control one's brain activity in this fashion may require longer or repeated rtfMRI training sessions.

Assessing Sustainable Developments in a Coastal Region: the Garolim Bay in the West Coast of Korea

Park, M. J.

2016-12-01

The Garolim Bay is a semi-enclosed bay located in the west coast of Korea and has a spring tidal range over 6 m. It is well known for vast tidal flats and healthy ecosystems that supports high productive and diverse marine lives. Due to its large tidal range it was considered favorable site for the construction of tidal power plant and went through controversies over decades. Local fishermen depending on their livelihood over generations strongly opposed the construction, so did the most environmental groups. They argued that construction of the tidal barrage at the entrance of the bay will reduce the tidal range resulting in increase of mud content of bottom sediments and disruption of marine lives. On the other hand, the power generation industry and some local residents supported the construction arguing that the tidal power is renewable energy and contributes to reduction of CO2 emission along with economic benefits from tourists' sightseeing of the tidal power plant. The application of the tidal power plant construction at the Garolim Bay was not approved by the Korean government due to the concerns of environmental impacts on the marine lives of the Garolim Bay region. This study briefly reviews developments associated with the tidal power plant construction in the Garolim Bay and considers how to approach the assessment of the sustainable development of the coastal region of the Garolim Bay in accordance with UN Sustainable Development Goals (SDG) 2030 with appropriate goals, targets and monitoring indicators. It will be of keen interests to policy makers of central and local governments as well as local residents to monitor and find out the benefits pursuing SDG in the Garolim Bay where conflicts of interests among stakeholders persisted, and may exemplify the case for other regions of similar situations.

Conditions for the Emergence of Shared Norms in Populations with Incompatible Preferences

2014-01-01

Understanding norms is a key challenge in sociology. Nevertheless, there is a lack of dynamical models explaining how one of several possible behaviors is established as a norm and under what conditions. Analysing an agent-based model, we identify interesting parameter dependencies that imply when two behaviors will coexist or when a shared norm will emerge in a heterogeneous society, where different populations have incompatible preferences. Our model highlights the importance of randomness, spatial interactions, non-linear dynamics, and self-organization. It can also explain the emergence of unpopular norms that do not maximize the collective benefit. Furthermore, we compare behavior-based with preference-based punishment and find interesting results concerning hypocritical punishment. Strikingly, pressuring others to perform the same public behavior as oneself is more effective in promoting norms than pressuring others to meet one’s own private preference. Finally, we show that adaptive group pressure exerted by randomly occuring, local majorities may create norms under conditions where different behaviors would normally coexist. PMID:25166137

Octameric silsesquioxanes (RSiO(1.5))(8) are versatile and interesting nano building blocks, suitable for the synthesis of nanocomposites with controlled porosity. In this paper, we revisit the (29)Si and (13)C solid state NMR spectroscopy for this class of materials, by using GIPAW (gauge including projected augmented wave) first principles calculations [Pickard & Mauri, Phys. Rev. B, 2001, 63, 245101]. Full tensorial data, including the chemical shift anisotropies (CSA) and the absolute orientation of the corresponding principal axes systems (PAS), were calculated. Subsequent averaging of the calculated tensors (due to fast reorientation of the R groups around the Si-C bonds) allowed for the interpretation of the strong reduction of CSA and dipolar couplings for these derivatives. Good agreement was observed between the averaged calculated data and the experimental parameters. Interesting questions related to the interplay between X-ray crystallography and solid state NMR are raised and will be emphasized.

Because secretive marsh birds are difficult to detect, population status and habitat use for these birds are not well known. We conducted repeated surveys for secretive marsh birds across 264 sites in the Upper Mississippi River and Great Lakes Joint Venture region to estimate abundance, occupancy, and detection probabilities during the 2008 and 2009 breeding seasons. We identified species groups based on observed species co-occurrences. Two species, least bittern Ixobrychus exilis and American bittern Botaurus lentiginosus, co-occurred with other species less often than expected by chance, and two species groups, rails (Virginia rail Rallus limicola and sora Porzana carolina) and open-water birds (pied-billed grebe Podilymbus podiceps, common moorhen Gallinula chloropus, and American coot Fulica americana; coots were only surveyed in 2009), co-occurred more often than expected by chance. These groupings were consistent between years. We then estimated the relation of these species and groups to landscape and local site characteristics by using zero-inflated abundance models that accounted for incomplete detection. At the landscape level (5-km radius), the amount of emergent herbaceous wetland was positively associated with least bittern occupancy, whereas the amount of woody wetland was negatively associated with least bittern, rail, and open-water bird occupancy. At the local level, habitat variables that were associated with abundance were not consistent among groups or between years, with the exception that both least bitterns and open-water birds had a strong positive association between abundance and water-vegetation interspersion. Land managers interested in marsh bird management or conservation may want to consider focusing efforts on landscapes with high amounts of emergent herbaceous wetland and low amounts of woody wetland, and managing for high amounts of water-vegetation interspersion within the wetland.

Controlling Androgen receptor nuclear localization by dendrimer conjugates

NASA Astrophysics Data System (ADS)

Wang, Haoyu

Androgen Receptor (AR) antagonists, such as bicalutamide and flutamide have been used widely in the treatment of prostate cancer. Although initial treatment is effective, prostate cancer cells often acquire antiandrogen resistance with prolonged treatment. AR over-expression and AR mutations contribute to the development of antiandrogen resistant cancer. Second generation antiandrogens such as enzalutamide are more effective and show reduced AR nuclear localization. In this study, derivatives of PAN52, a small molecule antiandrogen previously developed in our lab, were conjugated to the surface of generation 4 and generation 6 PAMAM dendrimers to obtain antiandrogen PAMAM dendrimer conjugates (APDC). APDCs readily enter cells and associate with AR in the cytoplasm. Due to their large size and positive charge, they can not enter the nucleus, thus retaining AR in the cytoplasm. In addition, APDCs are effective in decreasing AR mediated transcription and cell proliferation. APDC is the first AR antagonists that inhibit DHT-induced nuclear localization of AR. By inhibiting AR nuclear localization, APDC represents a new class of antiandrogens that offer an alternative approach to addressing antiandrogen-resistant prostate cancer. Lysine post-translational modification of AR Nuclear Localization Sequence (NLS) has great impact on AR cellular localization. It is of interest to understand which modifications modulate AR translocation into the nucleus. In this study, we prepared dendrimer-based acetyltransferase mimetic (DATM), DATM is able to catalytically acetylate AR in CWR22Rv1 cells, which will be a useful tool for studying AR modification effect on AR cellular localization. Derivatives of DATM, which transfer other chemical groups to AR, can be prepared similarly, and with more dendrimer based AR modification tools prepared in future, we will be able to understand and control AR cellular localization through AR modification.

The focus and funding of US healthcare is evolving from volume to value-based, and healthcare leaders, managers, payers, and researchers are increasingly focusing on managing populations of patients. Simultaneously, there is increasing interest in getting "upstream" from disease management to promote health and prevent disease. Hence, the term "population health" has both clinical and community-based connotations relevant to the tripartite mission of US medical schools. To seek broad input for the strategic development of the Department of Population Health in a new medical school at a tier 1 research university. Focus groups with facilitated consensus development. Eighty-one persons representing the Dell Medical School and other schools at the University of Texas at Austin, city/county government, community nonprofit organizations, and faculty from other local university schools along with selected national academic leaders. Focus groups with subsequent consensus development of emphases identified premeeting by participants by e-mail exchanges. The resulting departmental strategic plan included scope of work, desired characteristics of leaders, and early impact activities in seven areas of interest: community engagement and health equity, primary care and value-based health, occupational and environment medicine, medical education, health services and community-based research, health informatics and data analysis, and global health. Medical schools should have a primary focus in population, most effectively at the departmental level. Engaging relevant academic and community stakeholders is an effective model for developing this emerging discipline in US medical schools.

Predictors of patrol officer interest in cybercrime training and investigation in selected United States police departments.

PubMed

Holt, Thomas J; Bossler, Adam M

2012-09-01

Cybercrime has created substantial challenges for law enforcement, particularly at the local level. Most scholars and police administrators believe that patrol officers need to become more effective first responders to cybercrime calls. The evidence illustrates, however, that many patrol officers are neither adequately prepared nor strongly interested in taking an active role in addressing cybercrime at the local level. This study, therefore, examined the factors that predicted patrol officer interest in cybercrime training and investigations in two southeastern U.S. cities. The study specifically examined the relationship between demographics, cybercrime exposure, computer training, computer proficiency, Internet and cybercrime perceptions, and views on policing cybercrime with officer interest in cybercrime investigation training and conducting cybercrime investigations in the future. Officer views on policing cybercrime, particularly whether they valued cybercrime investigations and believed that cybercrime would dramatically change policing, along with their computer skills, were the strongest predictors of interest in cybercrime efforts. Officers who had received previous computer training were less interested in additional training and conducting investigations. These findings support the argument that more command and departmental meetings focusing on the value of investigating these types of crime need to be held in order to increase officer interest.

Resilience at the border: traditional botanical knowledge among Macedonians and Albanians living in Gollobordo, Eastern Albania

PubMed Central

2014-01-01

Background Ethnobotany in South-Eastern Europe is gaining the interest of several scholars and stakeholders, since it is increasingly considered a key point for the re-evaluation of local bio-cultural heritage. The region of Gollobordo, located in Eastern Albania and bordering the Republic of Macedonia, is of particular interest for conducting ethnobiological studies, since it remained relatively isolated for the larger part of the 20th Century and is traditionally inhabited by a majority of ethnic Macedonians and a minority of Albanians (nowadays both sharing the Muslim faith). Methods An ethnobotanical survey focused on local food, medicinal, and veterinary plant uses was conducted with 58 participants using open and semi-structured interviews and via participant observation. Results We recorded and identified 115 taxa of vascular plants, which are locally used for food, medicinal, and veterinary purposes (representing 268 total plant reports). The Macedonian Traditional Ecological Knowledge (TEK) was greater than the Albanian TEK, especially in the herbal and ritual domains. This phenomenon may be linked to the long socio-cultural and linguistic isolation of this group during the time when the borders between Albania and the former Yugoslavia were completely closed. Moreover, the unusual current food utilisation of cooked potatoes leaves, still in use nowadays among Macedonians, could represent the side effect of an extreme adaptation that locals underwent over the past century when the introduction of the potato crop made new strategies available for establishing stable settlements around the highest pastures. Additionally, the difference in use of Helichrysum plicatum, which is popular in the local Macedonian folk medicine but absent among Albanians, confirms the particular significance of this taxon as it relates to the yellow colour of its flowers in South Slavic folklore. Conclusion Botanical studies with an ethnographic approach are crucial for understanding patterns of use of plants within given cultures. Importantly, such studies can also allow for analysis of the dynamics of change in these TEK patterns over the time. The results of this study may be important as baseline data set to be used in rural development programs in Gollobordo, aimed at fostering community-based strategies of management of natural resources.

Money versus mission at an African-American medical school: Knoxville College Medical Department, 1895-1900.

PubMed

Savitt, T L

2001-01-01

Knoxville College Medical Department (KCMD) was, to all appearances, a missionary medical school established in 1895 by a small black Presbyterian college in the Tennessee mountains to train African-American physicians. In reality, it functioned as a proprietary medical school organized and operated by a group of local white physicians who were more interested in making money than in furthering the school's mission of educating black Christian physicians. KCMD limped along until 1900 when the college's new president reported to the trustees about the white faculty's greed, irreligious behavior, poor teaching, and bad medical reputation, and about how the presence of the medical school on campus undermined the college's overall mission. KCMD graduated two students before closing its doors in 1900. A group of faculty then reopened the school off-campus as the Knoxville Medical College. That school closed in 1910.

How multiagency partnerships can successfully address large-scale pollution problems: a Hawaii case study.

Donohue, Mary J

2003-06-01

Oceanic circulation patterns deposit significant amounts of marine pollution, including derelict fishing gear from North Pacific Ocean fisheries, in the Hawaiian Archipelago [Mar. Pollut. Bull. 42(12) (2001) 1301]. Management responsibility for these islands and their associated natural resources is shared by several government authorities. Non-governmental organizations (NGOs) and private industry also have interests in the archipelago. Since the marine debris problem in this region is too large for any single agency to manage, a multiagency marine debris working group (group) was established in 1998 to improve marine debris mitigation in Hawaii. To date, 16 federal, state, and local agencies, working with industry and NGOs, have removed 195 tons of derelict fishing gear from the Northwestern Hawaiian Islands. This review details the evolution of the partnership, notes its challenges and rewards, and advocates its continued use as an effective resource management tool.

Pinus pinaster Ait. is a major resin producing species in Spain. Genetic linkage mapping can facilitate marker-assisted selection (MAS) through the identification of Quantitative Trait Loci and selection of allelic variants of interest in breeding populations. In this study, we report annotated genetic linkage maps for two individuals (C14 and C15) belonging to a breeding program aiming to increase resin production. We use different types of DNA markers, including last-generation molecular markers. We obtained 13 and 14 linkage groups for C14 and C15 maps, respectively. A total of 211 and 215 markers were positioned on each map and estimated genome length was between 1,870 and 2,166 cM respectively, which represents near 65% of genome coverage. Comparative mapping with previously developed genetic linkage maps for P. pinaster based on about 60 common markers enabled aligning linkage groups to this reference map. The comparison of our annotated linkage maps and linkage maps reporting QTL information revealed 11 annotated SNPs in candidate genes that co-localized with previously reported QTLs for wood properties and water use efficiency. This study provides genetic linkage maps from a Spanish population that shows high levels of genetic divergence with French populations from which segregating progenies have been previously mapped. These genetic maps will be of interest to construct a reliable consensus linkage map for the species. The importance of developing functional genetic linkage maps is highlighted, especially when working with breeding populations for its future application in MAS for traits of interest.

The US Coast Guard Academy, an undergraduate military Academy, in New London CT, provides STEM education programs to the local community that engage the public on hot topics in ocean sciences. Outreach efforts include classroom, lab, and field-based activities at the Academy as well as at local schools. In one course, we partner with a STEM high school collecting fish and environmental data on board a research vessel and subsequently students present the results of their project. In another course, cadets develop and present interactive demonstrations of marine science to local school groups. In addition, the Academy develops In another course, cadets develop and present interactive demonstrations of marine science to local school groups. In addition, the Academy develops and/or participates in outreach programs including Science Partnership for Innovation in Learning (SPIL), Women in Science, Physics of the Sea, and the Ocean Exploration Trust Honors Research Program. As part of the programs, instructors and cadets create interactive and collaborative activities that focus on hot topics in ocean sciences such as oil spill clean-up, ocean exploration, tsunamis, marine biodiversity, and conservation of aquatic habitats. Innovative science demonstrations such as real-time interactions with the Exploration Vessel (E/V) Nautilus, rotating tank simulations of ocean circulation, wave tank demonstrations, and determining what materials work best to contain and clean-up oil, are used to enhance ocean literacy. Children's books, posters and videos are some creative ways students summarize their understanding of ocean sciences and marine conservation. Despite time limitations of students and faculty, and challenges associated with securing funding to keep these programs sustainable, the impact of the programs is overwhelmingly positive. We have built stronger relationships with local community, enhanced ocean literacy, facilitated communication and mentorship between young students and scientists, and encouraged interest of underrepresented minorities in STEM education.

Purpose To investigate the impact of the Orthopaedic Surgery and Sports Medicine Interest Group (OSSMIG) on medical student interest and confidence in core musculoskeletal (MSK) concepts through supplemental education and experiences at a single tertiary, academic institution. Methods Medical student OSSMIG members at various levels of training were anonymously surveyed at the beginning and end of the 2014–2015 academic year. Results Eighteen (N=18) medical student interest group members completed the survey. Significant improvement in their level of training was observed with regard to respondents’ self-assessed competence and confidence in MSK medicine (p<0.05). Additionally, respondents’ attitudes toward exposure and support from the interest group were significantly higher than those provided by the institution (p<0.05). Members believed OSSMIG increased interest in MSK medicine, improved confidence in their ability to perform orthopedics-related physical exams, strengthened mentorship with residents and attendings, and developed a connection with the Department of Orthopedic Surgery and its residents (median “Strongly Agree”, interquartile range one and two scale items). Conclusion Since its inception 8 years ago, OSSMIG has been well received and has positively impacted University of Washington School of Medicine students through various interventions. Surgical interest groups should target both the students interested in primary care and surgery. Medical schools can provide additional exposure to MSK medicine by leveraging interest groups that provide early clinical experiences and supplementary instruction. PMID:28814909

Adaptation as a political process: adjusting to drought and conflict in Kenya's drylands.

PubMed

Eriksen, Siri; Lind, Jeremy

2009-05-01

In this article, we argue that people's adjustments to multiple shocks and changes, such as conflict and drought, are intrinsically political processes that have uneven outcomes. Strengthening local adaptive capacity is a critical component of adapting to climate change. Based on fieldwork in two areas in Kenya, we investigate how people seek to access livelihood adjustment options and promote particular adaptation interests through forming social relations and political alliances to influence collective decision-making. First, we find that, in the face of drought and conflict, relations are formed among individuals, politicians, customary institutions, and government administration aimed at retaining or strengthening power bases in addition to securing material means of survival. Second, national economic and political structures and processes affect local adaptive capacity in fundamental ways, such as through the unequal allocation of resources across regions, development policy biased against pastoralism, and competition for elected political positions. Third, conflict is part and parcel of the adaptation process, not just an external factor inhibiting local adaptation strategies. Fourth, there are relative winners and losers of adaptation, but whether or not local adjustments to drought and conflict compound existing inequalities depends on power relations at multiple geographic scales that shape how conflicting interests are negotiated locally. Climate change adaptation policies are unlikely to be successful or minimize inequity unless the political dimensions of local adaptation are considered; however, existing power structures and conflicts of interests represent political obstacles to developing such policies.

To describe the knowledge of, and experience with, the Interest Group in Family Medicine (IgFM) at the University of Toronto, among undergraduate medical students; to explore the effects of the IgFM on undergraduate medical students; and to help determine future directions for the IgFM and other family medicine interest groups in Canada. Qualitative descriptive design and focus groups. The Faculty of Medicine at the University of Toronto in Ontario. A total of 45 students in the undergraduate medical school program at the University of Toronto participated in this study. Approximately equal numbers of students from each year were represented in the sample. Focus groups were conducted to determine students' knowledge of, experiences with, and perspectives on the IgFM. The focus groups were audiotaped and transcribed verbatim. Transcripts were coded and analyzed for themes using qualitative content analysis. Data were collected until saturation of emerging themes was reached. The students were generally knowledgeable about the IgFM and many had attended IgFM events. The IgFM had different effects on students depending on their level of interest in family medicine (FM). For those already interested in FM, the IgFM helped to maintain and support that interest. For students still undecided about their career choices, the IgFM helped to support continued interest in FM by dispelling negative myths about the discipline, providing positive peer influences, and supplying information about careers in FM. For students not interested in FM, the IgFM provided helpful information about the discipline. Students also had many useful suggestions regarding the future direction of the IgFM. The IgFM has been successful in increasing medical student exposure to FM and in supporting students' interest in this discipline. Information from this study also provides strategies for future direction to the IgFM and other family medicine interest groups in Canada and the United States.

While teachers have traditionally used the interesting objects to increase student attention in the classroom, evidence supporting the effectiveness of this method is lacking. The present study investigated the influence of different stimulus attributes for typical developing students and for students with attention deficit/hyperactivity disorder (ADHD) and dyslexia. Thirty children with ADHD, 30 children with dyslexia, and 30 typical developing students were tested using a measuring tool that was constructed by the authors to assess their sustained attention and selective attention on the geometric-figure assessment and the interesting-figure assessment. The geometric-figure assessment included a square, circle, trapezium, and triangle; and the interesting-figure assessment included a house, cat, hand, and tree. While the typical developing group showed better selective attention on the geometric-figure assessment, there was no difference between the dyslexic group and the ADHD group with respect to selective attention. Furthermore, the typical developing and dyslexic groups did not differ in the geometric-figure assessment in sustained attention and were both better in this area than the ADHD group. In the interesting-figure assessment, the typical developing and dyslexic groups performed similarly in sustained attention, but selective attention of the dyslexic group improved more than the ADHD group, similar to the typical developing group. Both selective attention of the dyslexic group and sustained attention of the ADHD group showed positive significant differences in the interesting-figure assessment, but sustained attention of the dyslexic group and selective attention of the ADHD group showed little difference in the interesting-figure assessment. Surprisingly, the typical developing group did not show any significant difference in the interesting-figure assessment, possibly because they had previously demonstrated a ceiling effect in the geometric-figure assessment.

Update on ropivacaine.

Wang, R D; Dangler, L A; Greengrass, R A

2001-12-01

Long-acting local anaesthetics are primarily used in the practice of anaesthesia, particularly in regional anaesthesia and analgesia. Ropivacaine is a new long-acting local anaesthetic that has been the focus of interest because of its increased cardiovascular safety compared with bupivacaine. Other advantages of ropivacaine over bupivacaine include a greater sensorimotor differential block and shorter elimination half-life (t(1/2)), with a lower potential for accumulation. The most important attribute of ropivacaine, however, is its increased margin of safety compared with bupivacaine when given in equal doses. Many post-marketing studies have focused on the comparisons of efficacy in blocks and toxicity profiles of bupivacaine versus ropivacaine. Recent animal toxicity studies confirm the results of original studies showing that ropivacaine has less cardiovascular toxicity than bupivacaine with respect to direct myocardial depression, success of resuscitation and arrhythmogenic potential when given in equal doses. Reduced cardiotoxicity may be a distinct characteristic of ropivacaine. A review of current literature suggests that, at clinically relevant doses, ropivacaine provides the lowest potential risk of cardiotoxicity for inadvertent intravascular injection. Studies are currently under way comparing ropivacaine with levobupivacaine, the latest addition to the group of long-acting local anaesthetics.

Exact correlators on the Wilson loop in N=4 SYM: localization, defect CFT, and integrability

NASA Astrophysics Data System (ADS)

Giombi, Simone; Komatsu, Shota

2018-05-01

We compute a set of correlation functions of operator insertions on the 1 /8 BPS Wilson loop in N=4 SYM by employing supersymmetric localization, OPE and the Gram-Schmidt orthogonalization. These correlators exhibit a simple determinant structure, are position-independent and form a topological subsector, but depend nontrivially on the 't Hooft coupling and the rank of the gauge group. When applied to the 1 /2 BPS circular (or straight) Wilson loop, our results provide an infinite family of exact defect CFT data, including the structure constants of protected defect primaries of arbitrary length inserted on the loop. At strong coupling, we show precise agreement with a direct calculation using perturbation theory around the AdS2 string worldsheet. We also explain the connection of our results to the "generalized Bremsstrahlung functions" previously computed from integrability techniques, reproducing the known results in the planar limit as well as obtaining their finite N generalization. Furthermore, we show that the correlators at large N can be recast as simple integrals of products of polynomials (known as Q-functions) that appear in the Quantum Spectral Curve approach. This suggests an interesting interplay between localization, defect CFT and integrability.

Particle-hole symmetry, many-body localization, and topological edge modes

NASA Astrophysics Data System (ADS)

Vasseur, Romain; Friedman, Aaron J.; Parameswaran, S. A.; Potter, Andrew C.

We study the excited states of interacting fermions in one dimension with particle-hole symmetric disorder (equivalently, random-bond XXZ chains) using a combination of renormalization group methods and exact diagonalization. Absent interactions, the entire many-body spectrum exhibits infinite-randomness quantum critical behavior with highly degenerate excited states. We show that though interactions are an irrelevant perturbation in the ground state, they drastically affect the structure of excited states: even arbitrarily weak interactions split the degeneracies in favor of thermalization (weak disorder) or spontaneously broken particle-hole symmetry, driving the system into a many-body localized spin glass phase (strong disorder). In both cases, the quantum critical properties of the non-interacting model are destroyed, either by thermal decoherence or spontaneous symmetry breaking. This system then has the interesting and counterintuitive property that edges of the many-body spectrum are less localized than the center of the spectrum. We argue that our results rule out the existence of certain excited state symmetry-protected topological orders.

Local renormalization group functions from quantum renormalization group and holographic bulk locality

DOE Office of Scientific and Technical Information (OSTI.GOV)

Nakayama, Yu

Here, the bulk locality in the constructive holographic renormalization group requires miraculous cancellations among various local renormalization group functions. The cancellation is not only from the properties of the spectrum but from more detailed aspects of operator product expansions in relation to conformal anomaly. It is remarkable that one-loop computation of the universal local renormalization group functions in the weakly coupled limit of the N = 4 super Yang-Mills theory fulfils the necessary condition for the cancellation in the strongly coupled limit in its SL(2, Z) duality invariant form. From the consistency between the quantum renormalization group and the holographicmore » renormalization group, we determine some unexplored local renormalization group functions (e.g. diffusive term in the beta function for the gauge coupling constant) in the strongly coupled limit of the planar N = 4 super Yang-Mills theory.« less

Inflammatory fibrotic disorders have been of high interest both for dermatologists and rheumatologists. Although the phenotypic end stage of this group of diseases is ultimately the same, namely fibrosis, patients present with different clinical features and are often treated with distinct therapeutic modalities. This review addresses whether there is evidence for different underlying molecular pathways in the various inflammatory fibrotic diseases such as localized scleroderma, pediatric lichen sclerosus, adult lichen sclerosus, eosinophilic fasciitis and systemic sclerosis. To investigate this, a large number of gene expression microarray studies performed on skin or fibroblasts from patients with these aforementioned diseases were described, (re-)analysed, and compared. As suspected by the heterogeneous phenotype, most diseases showed unique gene expression features. Intriguingly, a clear overlap was observed between adult and pediatric lichen sclerosus and localized scleroderma, in antigen processing and the interferon pathway. Delineating the cause and consequence of these pathways may generate novel tools to better characterize and more effectively treat these patients.

Combining near-field scanning optical microscopy with spectral interferometry for local characterization of the optical electric field in photonic structures.

PubMed

Trägårdh, Johanna; Gersen, Henkjan

2013-07-15

We show how a combination of near-field scanning optical microscopy with crossed beam spectral interferometry allows a local measurement of the spectral phase and amplitude of light propagating in photonic structures. The method only requires measurement at the single point of interest and at a reference point, to correct for the relative phase of the interferometer branches, to retrieve the dispersion properties of the sample. Furthermore, since the measurement is performed in the spectral domain, the spectral phase and amplitude could be retrieved from a single camera frame, here in 70 ms for a signal power of less than 100 pW limited by the dynamic range of the 8-bit camera. The method is substantially faster than most previous time-resolved NSOM methods that are based on time-domain interferometry, which also reduced problems with drift. We demonstrate how the method can be used to measure the refractive index and group velocity in a waveguide structure.

Communities of practice (CoPs) are among the professional development strategies most widely used in such fields as management and education. Though the approach has elicited keen interest, knowledge pertaining to its conceptual underpinnings is still limited, thus hindering proper assessment of CoPs' effects and the processes generating the latter. To address this shortcoming, this paper presents a conceptual model that was developed to evaluate an initiative based on a CoP strategy: Health Promotion Laboratories are a professional development intervention that was implemented in local public health organizations in Montreal (Quebec, Canada). The model is based on latest theories on work-group effectiveness and organizational learning and can be usefully adopted by evaluators who are increasingly called upon to illuminate decision-making about CoPs. Ultimately, validation of this conceptual model will help advance knowledge and practice pertaining to CoPs as well as professional and organizational development strategies in public health.

The conference was committed to community outreach, and we were delighted to ``pop-up'' in Chicago neighborhoods with a science program geared for children ages 6-18. We reached over 675 ``neighbors'' at 30 libraries citywide. The presentations were so successful that the libraries plan to host more presentations offered by Fermilab during the school year. We describe our experience as a model adaptable for other meetings and conferences or as part of a university outreach program and in partnership with other venues such park districts.

Biogeographic affinity helps explain productivity-richness relationships at regional and local scales

USGS Publications Warehouse

Harrison, S.; Grace, J.B.

2007-01-01

The unresolved question of what causes the observed positive relationship between large-scale productivity and species richness has long interested ecologists and evolutionists. Here we examine a potential explanation that we call the biogeographic affinity hypothesis, which proposes that the productivity-richness relationship is a function of species' climatic tolerances that in turn are shaped by the earth's climatic history combined with evolutionary niche conservatism. Using botanical data from regions and sites across California, we find support for a key prediction of this hypothesis, namely, that the productivity-species richness relationship differs strongly and predictably among groups of higher taxa on the basis of their biogeographic affinities (i.e., between families or genera primarily associated with north-temperate, semiarid, or desert zones). We also show that a consideration of biogeographic affinity can yield new insights on how productivity-richness patterns at large geographic scales filter down to affect patterns of species richness and composition within local communities. ?? 2007 by The University of Chicago.

Gilbert, Gregory S; Magarey, Roger; Suiter, Karl; Webb, Campbell O

2012-01-01

Assessing risk from a novel pest or pathogen requires knowing which local plant species are susceptible. Empirical data on the local host range of novel pests are usually lacking, but we know that some pests are more likely to attack closely related plant species than species separated by greater evolutionary distance. We use the Global Pest and Disease Database, an internal database maintained by the United States Department of Agriculture Animal and Plant Health Inspection Service – Plant Protection and Quarantine Division (USDA APHIS-PPQ), to evaluate the strength of the phylogenetic signal in host range for nine major groups of plant pests and pathogens. Eight of nine groups showed significant phylogenetic signal in host range. Additionally, pests and pathogens with more known hosts attacked a phylogenetically broader range of hosts. This suggests that easily obtained data – the number of known hosts and the phylogenetic distance between known hosts and other species of interest – can be used to predict which plant species are likely to be susceptible to a particular pest. This can facilitate rapid assessment of risk from novel pests and pathogens when empirical host range data are not yet available and guide efficient collection of empirical data for risk evaluation.

Does decentralisation enhance a school's role of promoting social cohesion? Bosnian school leaders' perceptions of school governance

NASA Astrophysics Data System (ADS)

Komatsu, Taro

2014-05-01

This study seeks to understand whether and how decentralised school governance in Bosnia and Herzegovina (BiH) enhances the schools' role of promoting social cohesion. This includes increasing "horizontal" trust among different ethnic groups and "vertical" trust between civilians and public institutes. The study examined secondary school leaders' perceptions regarding school board influence on social cohesion policies and practices, their interactions with school board members, and their accountability to the school-based governing body. The results show that school leaders and school boards, supposedly representing the interests of local stakeholders, did not appear to be actively engaged in the deliberate process of promoting social cohesion. While school directors tended to view themselves as being independent from the school boards, ethnically diverse school boards provided important support to proactive school leaders for their inter-group activities. Given that the central level is not providing initiatives to promote social cohesion and that BiH citizens appear to generally support social cohesion, decentralised school governance has the potential to improve social trust from the bottom up. To promote participatory school governance, the study recommends that BiH school leaders should be provided with opportunities to re-examine and redefine their professional accountability and to assist local stakeholders to improve their involvement in school governance.

The nucleotide excision repair (NER) disorder xeroderma pigmentosum (XP) is characterized by sun (UV) sensitivity, predisposition to skin cancer, and extensive genetic heterogeneity. Recently, we reported the cloning and analysis of three human NER genes, XPC, HHR23A, and HHR23B. The previously cloned XPC gene is involved in the common XP complementation group C, which is defective in excision repair of nontranscribed sequences in the genome. The XPC protein was found to be complexed with the product of HHR23B, one of the two human homologs of the Saccharomyes cerevisiae NER gene RAD23. Here we present the chromosomal localization by in situmore » hybridization using haptenized probes of all three genes. The HHR23A gene was assigned to chromosome 19p13.2. Interestingly, the HHR23B and XPC genes, the product of which forms a tight complex, were found to colocalize on band 3p25.1. Pulsed-field gel electrophoresis revealed that the HHR23B and XPC genes possibly share a MluI restriction fragment of about 625 kb. Potential involvement of the HHR23 genes in human genetic disorders is discussed. 53 refs., 4 figs., 2 tabs.« less

Helping women traders. Organizing for change: Nigeria.

PubMed

Obadina, E

1995-01-01

In Nigeria, the World Bank developed a pilot project, the Women's Management Training Outreach Programme (WMTOP), to improve the managerial skills of illiterate and semiliterate rural business women and farmers. In 1993, WMTOP chose the Country Women's Association of Nigeria (COWAN) for training. The result for a local group of cooperative kola nut traders was improved time management techniques, a more profitable division of labor, and the ability to keep better written financial records. WMTOP has taught women from 58 local groups (reaching 2600 women) the principles of human resource management, finance and credit, microproject management, and marketing. Although participants praise the project, a lack of money for business expansion continues to hold the women back from real success. Funding for WMTOP comes from the Economic Development Institute of the World Bank, which exists primarily to train government functionaries. This extension to include nongovernmental organizations in the training program is a result of the World Bank's effort to promote self-sufficiency. WMTOP attempts to take the program directly to the women, and the trainers live with the trainees in their home villages during the follow-up sessions. All of the WMTOP materials have been translated into Yoruba to eliminate misunderstandings. WMTOP seed money will end in 1996, but there is hope that this positive program will interest donors.

This study aims to describe the association between dietary habits and weight status and the interest in food and science. We examined in a cross-sectional study 525 children aged between 8 and 18 years, who attended the Brussels Food Fair or the Belgian Science Day in 2013. They were divided into three groups: special interest in science, special interest in food, and a general control group. They completed a questionnaire, and body parameters were measured. The weight status of the children was identified using the growth charts and the calculated BMI. In total, 525 children were included: 290 children in the reference group, 194 in the food group, and 41 in the science group. The prevalence of overweight and obesity was 28% in the general control group, 14% in the food group, and 15% in the science group. Breakfast and dinner were skipped more often by children with overweight or obesity. Children from the food and science groups had more sweets and meat, had less fruit, and skipped less meals. In our study, 28% of the reference group had overweight or obesity. The children with special interest in food or science differed from the control group.

Evaluation of the performance of diagnosis-related groups and similar casemix systems: methodological issues.

PubMed

Palmer, G; Reid, B

2001-05-01

With the increasing recognition and application of casemix for managing and financing healthcare resources, the evaluation of alternative versions of systems such as diagnosis-related groups (DRGs) has been afforded high priority by governments and researchers in many countries. Outside the United States, an important issue has been the perceived need to produce local versions, and to establish whether or not these perform more effectively than the US-based classifications. A discussion of casemix evaluation criteria highlights the large number of measures that may be used, the rationale and assumptions underlying each measure, and the problems in interpreting the results. A review of recent evaluation studies from a number of countries indicates that considerable emphasis has been placed on the predictive validity criterion, as measured by the R2 statistic. However, the interpretation of the findings has been affected greatly by the methods used, especially the treatment and definition of outlier cases. Furthermore, the extent to which other evaluation criteria have been addressed has varied widely. In the absence of minimum evaluation standards, it is not possible to draw clear-cut conclusions about the superiority of one version of a casemix system over another, the need for a local adaptation, or the further development of an existing version. Without the evidence provided by properly designed studies, policy-makers and managers may place undue reliance on subjective judgments and the views of the most influential, but not necessarily best informed, healthcare interest groups.

Converging evidence for abnormalities of the prefrontal cortex and evaluation of midsagittal structures in pediatric PTSD: an MRI study

Objective Volumetric imaging research has shown abnormal brain morphology in posttraumatic stress disorder (PTSD) when compared to controls. We present results on a study of brain morphology in the prefrontal cortex (PFC) and midline structures, via indices of gray matter volume and density, in pediatric PTSD. We hypothesized that both methods would demonstrate aberrant morphology in the PFC. Further, we hypothesized aberrant brainstem anatomy and reduced corpus collosum volume in children with PTSD. Methods Twenty-four children (aged 7-14) with history of interpersonal trauma and 24 age, and gender matched controls underwent structural magnetic resonance imaging. Images of the PFC and midline brain structures were first analyzed using volumetric image analysis. The PFC data were then compared with whole-brain voxel-based techniques using statistical parametric mapping (SPM). Results The PTSD group showed significant increased gray matter volume in the right and left inferior and superior quadrants of the prefrontal cortex and smaller gray matter volume in pons, and posterior vermis areas by volumetric image analysis. The voxel-byvoxel group comparisons demonstrated increased gray matter density mostly localized to ventral PFC as compared to the control group. Conclusions Abnormal frontal lobe morphology, as revealed by separate-complementary image analysis methods, and reduced pons and posterior vermis areas are associated with pediatric PTSD. Voxel-based morphometry may help to corroborate and further localize data obtained by volume of interest methods in PTSD. PMID:19349151

MIDAS: Regionally linear multivariate discriminative statistical mapping.

PubMed

Varol, Erdem; Sotiras, Aristeidis; Davatzikos, Christos

2018-07-01

Statistical parametric maps formed via voxel-wise mass-univariate tests, such as the general linear model, are commonly used to test hypotheses about regionally specific effects in neuroimaging cross-sectional studies where each subject is represented by a single image. Despite being informative, these techniques remain limited as they ignore multivariate relationships in the data. Most importantly, the commonly employed local Gaussian smoothing, which is important for accounting for registration errors and making the data follow Gaussian distributions, is usually chosen in an ad hoc fashion. Thus, it is often suboptimal for the task of detecting group differences and correlations with non-imaging variables. Information mapping techniques, such as searchlight, which use pattern classifiers to exploit multivariate information and obtain more powerful statistical maps, have become increasingly popular in recent years. However, existing methods may lead to important interpretation errors in practice (i.e., misidentifying a cluster as informative, or failing to detect truly informative voxels), while often being computationally expensive. To address these issues, we introduce a novel efficient multivariate statistical framework for cross-sectional studies, termed MIDAS, seeking highly sensitive and specific voxel-wise brain maps, while leveraging the power of regional discriminant analysis. In MIDAS, locally linear discriminative learning is applied to estimate the pattern that best discriminates between two groups, or predicts a variable of interest. This pattern is equivalent to local filtering by an optimal kernel whose coefficients are the weights of the linear discriminant. By composing information from all neighborhoods that contain a given voxel, MIDAS produces a statistic that collectively reflects the contribution of the voxel to the regional classifiers as well as the discriminative power of the classifiers. Critically, MIDAS efficiently assesses the statistical significance of the derived statistic by analytically approximating its null distribution without the need for computationally expensive permutation tests. The proposed framework was extensively validated using simulated atrophy in structural magnetic resonance imaging (MRI) and further tested using data from a task-based functional MRI study as well as a structural MRI study of cognitive performance. The performance of the proposed framework was evaluated against standard voxel-wise general linear models and other information mapping methods. The experimental results showed that MIDAS achieves relatively higher sensitivity and specificity in detecting group differences. Together, our results demonstrate the potential of the proposed approach to efficiently map effects of interest in both structural and functional data. Copyright © 2018. Published by Elsevier Inc.

Lattice-Assisted Spectroscopy: A Generalized Scanning Tunneling Microscope for Ultracold Atoms.

We propose a scheme to measure the frequency-resolved local particle and hole spectra of any optical lattice-confined system of correlated ultracold atoms that offers single-site addressing and imaging, which is now an experimental reality. Combining perturbation theory and time-dependent density matrix renormalization group simulations, we quantitatively test and validate this approach of lattice-assisted spectroscopy on several one-dimensional example systems, such as the superfluid and Mott insulator, with and without a parabolic trap, and finally on edge states of the bosonic Su-Schrieffer-Heeger model. We highlight extensions of our basic scheme to obtain an even wider variety of interesting and important frequency resolved spectra.

Single-photon tomographic determination of regional cerebral blood flow in epilepsy

Using a single-photon emission computed tomographic scanner (SPECT) the authors determined regional cerebral blood flow (rCBF) with inhaled xenon-133, a noninvasive procedure. Studies were performed in 40 normal individuals, and these were compared with rCBF determinations in 51 patients with seizure disorders. Although positive results were obtained in 15 of 16 patients with mass lesions, the group of principal interest comprised 25 patients suffering from ''temporal lobe'' epilepsy. Only one of these had a positive x-ray computed tomogram, but 16 had positive findings on rCBF study. These findings included increased local blood flow in the ictal state and reduced flowmore » interictally.« less

Monoterpenes, the major components of essential oils, belong to the group of isoprenoids containing ten carbon atoms. Being widely distributed in the plant kingdom they are extensively used in cuisine and human health care products. Studies have shown that both natural monoterpenes and their synthetic derivatives are endowed with various pharmacological properties including antifungal, antibacterial, antioxidant, anticancer, antiarrhythmic, anti-aggregating, local anesthetic, antinociceptive, anti-inflammatory, antihistaminic and anti-spasmodic activities. Monoterpenes act also as regulators of growth, heat, transpiration, tumor inhibitors, inhibitors of oxidative phosphorylation, insect repellants, feline and canine attractants and antidiabetics. These interesting activities which might be potentially used not only in pharmaceutical, but also food and cosmetic industries are discussed below.

Integrating Native knowledge and community perspectives in geoscience research and education

2010-12-01

Multiple perspectives are being incorporated in geoscience research and education exemplified by ongoing projects at the University of Alaska Fairbanks. This presentation will highlight two such projects. In the Seasons and Biomes project, that monitors seasons through global learning communities, in an effort to increase K-12 student understanding of Earth as a system and the environmental changes occurring in their local environment, students are accessing different knowledge systems in their studies. During professional development workshops for K-12 teachers, Alaska Native elders and community experts have been invited to be part of the scientist-educator team to help teachers engage their students in geoscience studies. Teachers learn and practice scientific measurement protocols in investigations such as atmosphere/weather, phenology and hydrology, learn about increasing their observation skills and systems thinking and how to engage and guide their students in environmental investigations. Native elders have been involved in classroom projects to help students understand what changes have occurred and currently occurring in their villages. They have also been involved in projects where small groups of students have conducted investigations under their guidance and the teachers’/scientists’ guidance. A student group from Shageluk, Alaska, successfully completed their study on effects of environmental changes and fire, and was invited and funded along with their Native mentor, to present their findings at an international student conference. In the Stakeholders and Climate Change project, fieldwork, meetings and numerous interviews have been conducted with Tanana, Ft. Yukon, and Chalkyitsik elders and middle-aged travelers and subsistence users. These video-taped interviews have been transcribed, digitized and processed into a draft Alaska Stakeholders and Climate Change/Project Jukebox website using Drupal CMA to create and maintain dynamic content and XSLT to create synchronized transcription. Interviews also have been analyzed and sorted according to 6 emerging themes: weather, rivers and lakes, fire, permafrost, plants and animals, and seasonality. Additionally, an interview “sampler” has been produced in DVD format for sharing with communities. This past February, we conducted a Stakeholders and Climate Change Workshop that melded local and indigenous observations and scientific research. Residents of Fort Yukon, Chalkyitsik and Tanana, Alaska and IARC and other UAF scientists met for two days to discuss changes in weather, climate, seasonality and the effects on landscape, subsistence resources and activities. Participating scientists were stimulated by the questions and observations of local residents and are interested in how their knowledge and future investigations might align more directly with local concerns. Local residents were appreciative of attention to their climate change concerns and are particularly interested in how their observations link to scientific explanations and to climate change forecasts for their specific location and getting climate change information out to communities and schools.

Meditation has lately received considerable interest from cognitive neuroscience. Studies suggest that daily meditation leads to long lasting attentional and neuronal plasticity. We present changes related to the attentional systems before and after a 3 month intensive meditation retreat. We used three behavioral psychophysical tests - a Stroop task, an attentional blink task, and a global-local letter task-to assess the effect of Isha yoga meditation on attentional resource allocation. 82 Isha yoga practitioners were tested at the beginning and at the end of the retreat. Our results showed an increase in correct responses specific to incongruent stimuli in the Stroop task. Congruently, a positive correlation between previous meditation experience and accuracy to incongruent Stroop stimuli was also observed at baseline. We also observed a reduction of the attentional blink. Unexpectedly, a negative correlation between previous meditation experience and attentional blink performance at baseline was observed. Regarding spatial attention orientation as assessed using the global-local letter task, participants showed a bias toward local processing. Only slight differences in performance were found pre- vs. post- meditation retreat. Biasing toward the local stimuli in the global-local task and negative correlation of previous meditation experience with attentional blink performance is consistent with Isha practices being focused-attention practices. Given the relatively small effect sizes and the absence of a control group, our results do not allow clear support nor rejection of the hypothesis of meditation-driven neuronal plasticity in the attentional system for Isha yoga practice.

Functional Maps of Neocortical Local Circuitry

Thomson, Alex M.; Lamy, Christophe

2007-01-01

This review aims to summarize data obtained with different techniques to provide a functional map of the local circuit connections made by neocortical neurones, a reference for those interested in cortical circuitry and the numerical information required by those wishing to model the circuit. A brief description of the main techniques used to study circuitry is followed by outline descriptions of the major classes of neocortical excitatory and inhibitory neurones and the connections that each layer makes with other cortical and subcortical regions. Maps summarizing the projection patterns of each class of neurone within the local circuit and tables of the properties of these local circuit connections are provided. This review relies primarily on anatomical studies that have identified the classes of neurones and their local and long distance connections and on paired intracellular and whole-cell recordings which have documented the properties of the connections between them. A large number of different types of synaptic connections have been described, but for some there are only a few published examples and for others the details that can only be obtained with paired recordings and dye-filling are lacking. A further complication is provided by the range of species, technical approaches and age groups used in these studies. Wherever possible the range of available data are summarised and compared. To fill some of the more obvious gaps for the less well-documented cases, data obtained with other methods are also summarized. PMID:18982117

An important challenge in Web-based health promotion is to increase the reach of the target audience by taking the target groups' desires into consideration. Data from 505 members of a Dutch Internet panel (representative for Dutch Internet users) were used to asses the target group's interests and needs. 28% participated in Web-based tailored lifestyle programs, 57% expressed an interest in such programs, and 15% expressed no interest. Interest in Web-based programs was predominantly caused by a general interest in lifestyle and online tests. Participation in Web-based tailored lifestyle programs should not take more than 17 minutes per occasion. 84% were interested in follow-up testing after the initial participation. Responders were particularly interested in physical activity and nutrition. Hardly anyone was willing to pay for participation. The results from this study support the use of Web-based tailored lifestyle programs in behavior change efforts.

Preprocessing of region of interest localization based on local surface curvature analysis for three-dimensional reconstruction with multiresolution

NASA Astrophysics Data System (ADS)

Li, Wanjing; Schütze, Rainer; Böhler, Martin; Boochs, Frank; Marzani, Franck S.; Voisin, Yvon

2009-06-01

We present an approach to integrate a preprocessing step of the region of interest (ROI) localization into 3-D scanners (laser or stereoscopic). The definite objective is to make the 3-D scanner intelligent enough to localize rapidly in the scene, during the preprocessing phase, the regions with high surface curvature, so that precise scanning will be done only in these regions instead of in the whole scene. In this way, the scanning time can be largely reduced, and the results contain only pertinent data. To test its feasibility and efficiency, we simulated the preprocessing process under an active stereoscopic system composed of two cameras and a video projector. The ROI localization is done in an iterative way. First, the video projector projects a regular point pattern in the scene, and then the pattern is modified iteratively according to the local surface curvature of each reconstructed 3-D point. Finally, the last pattern is used to determine the ROI. Our experiments showed that with this approach, the system is capable to localize all types of objects, including small objects with small depth.

Defects and oxidation of group-III monochalcogenide monolayers

NASA Astrophysics Data System (ADS)

Guo, Yu; Zhou, Si; Bai, Yizhen; Zhao, Jijun

2017-09-01

Among various two-dimensional (2D) materials, monolayer group-III monochalcogenides (GaS, GaSe, InS, and InSe) stand out owing to their potential applications in microelectronics and optoelectronics. Devices made of these novel 2D materials are sensitive to environmental gases, especially O2 molecules. To address this critical issue, here we systematically investigate the oxidization behaviors of perfect and defective group-III monochalcogenide monolayers by first-principles calculations. The perfect monolayers show superior oxidation resistance with large barriers of 3.02-3.20 eV for the dissociation and chemisorption of O2 molecules. In contrast, the defective monolayers with single chalcogen vacancy are vulnerable to O2, showing small barriers of only 0.26-0.36 eV for the chemisorption of an O2 molecule. Interestingly, filling an O2 molecule to the chalcogen vacancy of group-III monochalcogenide monolayers could preserve the electronic band structure of the perfect system—the bandgaps are almost intact and the carrier effective masses are only moderately disturbed. On the other hand, the defective monolayers with single vacancies of group-III atoms carry local magnetic moments of 1-2 μB. These results help experimental design and synthesis of group-III monochalcogenides based 2D devices with high performance and stability.

Wang, Jordan V; Korta, Dorota Z; Keller, Matthew

2017-11-15

This commentary addresses the increasingly competitive nature of applying to dermatology residency programs and how both interest groups in medical schools and their dermatology departments can help to better prepare applicants. As previous literature argued that dermatology has been underemphasized in medical school curricula, we propose five fundamental options that interest groups can implement in order to offer increased exposure to our field in medical training. Furthermore, with therecent trend of many schools conferring certificates in various specialized concentrations, we also discuss interest groups pioneering certificate-grantingprograms in dermatology competency. The pros and cons of having a recognized certificate program in dermatology are presented.

Interest in nephrology careers among internal medicine residents in the United States is declining. Our objective was to assess the impact of the presence of a nephrology fellowship training program on perceptions and career interest in nephrology among internal medicine residents. A secondary objective was to identify commonly endorsed negative perceptions of nephrology among internal medicine residents. This was a repeated cross-sectional survey of internal medicine residents before (Group 1) and 3 years after (Group 2) the establishment of nephrology fellowship programs at two institutions. The primary outcome was the percentage of residents indicating nephrology as a career interest in Group 1 vs. Group 2. Secondary outcomes included the frequency that residents agreed with negative statements about nephrology. 131 (80.9%) of 162 residents completed the survey. 19 (14.8%) residents indicated interest in a nephrology career, with 8 (6.3%) indicating nephrology as their first choice. There was no difference in career interest in nephrology between residents who were exposed to nephrology fellows during residency training (Group 2) and residents who were not (Group 1). The most commonly endorsed negative perceptions of nephrology were: nephrology fellows have long hours/burdensome call (36 [28.1%] of residents agreed or strongly agreed), practicing nephrologists must take frequent/difficult call (35 [27.6%] agreed or strongly agreed), and nephrology has few opportunities for procedures (35 [27.3%] agreed or strongly agreed). More residents in Group 2 agreed that nephrology is poorly paid (8.9% in Group 1 vs. 20.8% in Group 2, P = 0.04), whereas more residents in Group 1 agreed that nephrologists must take frequent/difficult call (40.0% in Group 1 vs. 18.1% in Group 2, P = 0.02). The initiation of a nephrology fellowship program was not associated with an increase in internal medicine residents' interest in nephrology careers. Residents endorsed several negative perceptions of nephrology, which may affect career choice.

To assess the clinical effectiveness and cost effectiveness of a policy to provide breastfeeding groups for pregnant and breastfeeding women. Cluster randomised controlled trial with prospective mixed method embedded case studies to evaluate implementation processes. Primary care in Scotland. Pregnant women, breastfeeding mothers, and babies registered with 14 of 66 eligible clusters of general practices (localities) in Scotland that routinely collect breastfeeding outcome data. Localities set up new breastfeeding groups to provide population coverage; control localities did not change group activity. any breast feeding at 6-8 weeks from routinely collected data for two pre-trial years and two trial years. any breast feeding at birth, 5-7 days, and 8-9 months; maternal satisfaction. Between 1 February 2005 and 31 January 2007, 9747 birth records existed for intervention localities and 9111 for control localities. The number of breastfeeding groups increased from 10 to 27 in intervention localities, where 1310 women attended, and remained at 10 groups in control localities. No significant differences in breastfeeding outcomes were found. Any breast feeding at 6-8 weeks declined from 27% to 26% in intervention localities and increased from 29% to 30% in control localities (P=0.08, adjusted for pre-trial rate). Any breast feeding at 6-8 weeks increased from 38% to 39% in localities not participating in the trial. Women who attended breastfeeding groups were older (P<0.001) than women initiating breast feeding who did not attend and had higher income (P=0.02) than women in the control localities who attended postnatal groups. The locality cost was pound13 400 (euro14 410; $20 144) a year. A policy for providing breastfeeding groups in relatively deprived areas of Scotland did not improve breastfeeding rates at 6-8 weeks. The costs of running groups would be similar to the costs of visiting women at home. Current Controlled Trials ISRCTN44857041.

The aim of this study was to develop a presurgical magnetoencephalography (MEG) protocol to localize and lateralize expressive and receptive language function as well as verbal memory in patients with epilepsy. Two simple language tasks and a different analytical procedure were developed. Ten healthy participants and 13 epileptic patients completed two language tasks during MEG recording: a verbal memory task and a verbal fluency task. As a first step, principal component analyses (PCA) were performed on source data from the group of healthy participants to identify spatiotemporal factors that were relevant to these paradigms. Averaged source data were used to localize areas activated during each task and a laterality index (LI) was computed on an individual basis for both groups, healthy participants and patients, using sensor data. PCA revealed activation in the left temporal lobe (300 ms) during the verbal memory task, and from the frontal lobe (210 ms) to the temporal lobe (500 ms) during the verbal fluency task in healthy participants. Averaged source data showed activity in the left hemisphere (250-750 ms), in Wernicke's area, for all participants. Left hemisphere dominance was demonstrated better using the verbal memory task than the verbal fluency task (F1,19=4.41, p=0.049). Cohen's kappa statistic revealed 93% agreement (k=0.67, p=0.002) between LIs obtained from MEG sensor data and fMRI, the IAT, electrical cortical stimulation or handedness with the verbal memory task for all participants. At 74%, agreement results for the verbal fluency task did not reach statistical significance. Analysis procedures yielded interesting findings with both tasks and localized language-related activation. However, based on source localization and laterality indices, the verbal memory task yielded better results in the context of the presurgical evaluation of epileptic patients. The verbal fluency task did not add any further information to the verbal memory task as regards language localization and lateralization for most patients and healthy participants that would facilitate decision making prior to surgery.

Cooking over open fires using solid fuels is both common practice throughout much of the world and widely recognized to contribute to human health, environmental, and social problems. The public health burden of household air pollution includes an estimated four million premature deaths each year. To be effective and generate useful insight into potential solutions, cookstove intervention studies must select cooking technologies that are appropriate for local socioeconomic conditions and cooking culture, and include interdisciplinary measurement strategies along a continuum of outcomes. REACCTING (Research on Emissions, Air quality, Climate, and Cooking Technologies in Northern Ghana) is an ongoing interdisciplinary randomized cookstove intervention study in the Kassena-Nankana District of Northern Ghana. The study tests two types of biomass burning stoves that have the potential to meet local cooking needs and represent different "rungs" in the cookstove technology ladder: a locally-made low-tech rocket stove and the imported, highly efficient Philips gasifier stove. Intervention households were randomized into four different groups, three of which received different combinations of two improved stoves, while the fourth group serves as a control for the duration of the study. Diverse measurements assess different points along the causal chain linking the intervention to final outcomes of interest. We assess stove use and cooking behavior, cooking emissions, household air pollution and personal exposure, health burden, and local to regional air quality. Integrated analysis and modeling will tackle a range of interdisciplinary science questions, including examining ambient exposures among the regional population, assessing how those exposures might change with different technologies and behaviors, and estimating the comparative impact of local behavior and technological changes versus regional climate variability and change on local air quality and health outcomes. REACCTING is well-poised to generate useful data on the impact of a cookstove intervention on a wide range of outcomes. By comparing different technologies side by side and employing an interdisciplinary approach to study this issue from multiple perspectives, this study may help to inform future efforts to improve health and quality of life for populations currently relying on open fires for their cooking needs.

The essential tension between leadership and power: when leaders sacrifice group goals for the sake of self-interest.

PubMed

Maner, Jon K; Mead, Nicole L

2010-09-01

Throughout human history, leaders have been responsible for helping groups attain important goals. Ideally, leaders use their power to steer groups toward desired outcomes. However, leaders can also use their power in the service of self-interest rather than effective leadership. Five experiments identified factors within both the person and the social context that determine whether leaders wield their power to promote group goals versus self-interest. In most cases, leaders behaved in a manner consistent with group goals. However, when their power was tenuous due to instability within the hierarchy, leaders high (but not low) in dominance motivation prioritized their own power over group goals: They withheld valuable information from the group, excluded a highly skilled group member, and prevented a proficient group member from having any influence over a group task. These self-interested actions were eliminated when the group was competing against a rival outgroup. Findings provide important insight into factors that influence the way leaders navigate the essential tension between leadership and power.

Novel guanidine-containing molecular transporters based on lactose scaffolds: lipophilicity effect on the intracellular organellar selectivity.

PubMed

Biswas, Goutam; Jeon, Ock-Youm; Lee, Woo Sirl; Kim, Dong-Chan; Kim, Kyong-Tai; Lee, Suho; Chang, Sunghoe; Chung, Sung-Kee

2008-01-01

We have synthesized two lactose-based molecular transporters, each containing seven guanidine residues attached to the lactose scaffold through omega-aminocarboxylate linker chains of two different lengths, and have examined their cellular uptakes and intracellular and organellar localizations in HeLa cells, as well as their tissue distributions in mice. Both molecular transporters showed higher cellular uptake efficiencies than Arg8, and wide tissue distributions including the brain. Mitochondrial localization is of special interest because of its potential relevance to "mitochondrial diseases". Interestingly, it has been found that the intracellular localization sites of the G7 molecular transporters-namely either mitochondria or lysosomes and endocytic vesicles-are largely determined by the linker chain lengths, or their associated lipophilicities.

Hybrid cochlear implantation: quality of life, quality of hearing, and working performance compared to patients with conventional unilateral or bilateral cochlear implantation.

The objective of the present study is to evaluate the effect of hybrid cochlear implantation (hCI) on quality of life (QoL), quality of hearing (QoH), and working performance in adult patients, and to compare the long-term results of patients with hCI to those of patients with conventional unilateral cochlear implantation (CI), bilateral CI, and single-sided deafness (SSD) with CI. Sound localization accuracy and speech-in-noise test were also compared between these groups. Eight patients with high-frequency sensorineural hearing loss of unknown etiology were selected in the study. Patients with hCI had better long-term speech perception in noise than uni- or bilateral CI patients, but the difference was not statistically significant. The sound localization accuracy was equal in the hCI, bilateral CI, and SSD patients. QoH was statistically significantly better in bilateral CI patients than in the others. In hCI patients, residual hearing was preserved in all patients after the surgery. During the 3.6-year follow-up, the mean hearing threshold at 125-500 Hz decreased on average by 15 dB HL in the implanted ear. QoL and working performance improved significantly in all CI patients. Hearing outcomes with hCI are comparable to the results of bilateral CI or CI with SSD, but hearing in noise and sound localization are statistically significantly better than with unilateral CI. Interestingly, the impact of CI on QoL, QoH, and working performance was similar in all groups.

The federal government has traditionally given local school districts an indirect subsidy by allowing them to issue tax-exempt bonds. Because the bondholders pay no tax on the interest income, they are willing to take a bond bearing interest at, say, 4.5% rather than 6%. Such lower interest is great for the school district because it saves the…

2014-03-12

Six Medicago species were investigated to characterize and valorize plant genetic resources of pastoral interest in Morocco. Samples were obtained from the core collection of the South Australian Research and Development Institute (SARDI). The transferability of single sequence repeat markers of Medicago truncatula was successful with 97.6% efficiency across the five species. A total of 283 alleles and 243 genotypes were generated using seven SSR markers, confirming the high level of polymorphism that is characteristic of the Medicago genus, despite a heterozygosity deficit (HO = 0.378; HE = 0.705). In addition, a high level of gene flow was revealed among the species analyzed with significant intra-specific variation. The unweighted pair group method with arithmetic mean dendrogram generated by the dissimilarity matrix revealed that M. polymorpha and M. orbicularis are closely related, and that M. truncatula is likely the ancestral species. The Pearson correlation index revealed no significant correlations between the geographic distribution of the Moroccan species and genetic similarities, indicating local adaptation of these species to different ecological environments independent of their topographical proximities. The substantial genetic variation observed was likely due to the predominance of selfing species, the relative proximity of prospected sites, human impacts, and the nature of the SARDI core collections, which are selected for their high genetic diversity. The results of this first report on Moroccan Medicago species will be of great interest for establishing strategies aiming at reasonable management and selection programs for local and Mediterranean germplasm in the face of increasing environmental change.

Implementation of graphic health warning labels on tobacco products in India: the interplay between the cigarette and the bidi industries

Objectives To understand the competition between and among tobacco companies and health groups that led to graphical health warning labels (GHWL) on all tobacco products in India. Methods Analysis of internal tobacco industry documents in the Legacy Tobacco Document Library, documents obtained through Indias Right to Information ‘ Act, and news reports. Results Implementation of GHWLs in India reflects a complex interplay between the government and the cigarette and bidi industries, who have shared as well as conflicting interests. Joint lobbying by national-level tobacco companies (that are foreign subsidiaries of multinationals) and local producers of other forms of tobacco blocked GHWLs for decades and delayed the implementation of effective GHWLs after they were mandated in 2007. Tobacco control activists used public interest lawsuits and the Right to Information Act to win government implementation of GHWLs on cigarette, bidi and smokeless tobacco packs in May 2009 and rotating GHWLs in December 2011. Conclusions GHWLs in India illustrate how the presence of bidis and cigarettes in the same market creates a complex regulatory environment. The government imposing tobacco control on multinational cigarette companies led to the enforcement of regulation on local forms of tobacco. As other developing countries with high rates of alternate forms of tobacco use establish and enforce GHWL laws, the tobacco control advocacy community can use pressure on the multinational cigarette industry as an indirect tool to force implementation of regulations on other forms of tobacco.

Blaha, C.; Goetz, J.; Johnson, T.

2011-09-01

Through our International Year of Astronomy outreach effort, we established a sustainable astronomy program and curriculum in the Northfield, Minnesota community. Carleton College offers monthly open houses at Goodsell Observatory and donated its recently "retire" observing equipment to local schools. While public evenings continue to be popular, the donated equipment was underutilized due to a lack of trained student observing assistants. With sponsorship from NASA's IYA Student Ambassador program, the sustainable astronomy project began in 2009 to generate greater interest in astronomy and train middle school and high school students as observing assistants. Carleton physics majors developed curricular materials and instituted regular outreach programs for grades 6-12. The Northfield High School Astronomy Club was created, and Carleton undergraduates taught high school students how to use telescopes and do CCD imaging. During the summer of 2009, Carleton students began the Young Astronomers Summer Experience (YASE) program for middle school students and offered a two-week, astronomy-rich observing and imaging experience at Goodsell Observatory. In concert with NASA's Summer of Innovation initiative, the YASE program was offered again in 2010 and engaged a new group of local middle school students in hands-on scientific experiments and observing opportunities. Members of the high school astronomy club now volunteer as observing assistants in the community and graduates of the YASE programs are eager to continue observing as members of a public service astronomy club when they enter the Northfield High School. These projects are training future scientists and will sustain the public's interest in astronomy long after the end of IYA 2009.

Nursing leadership succession planning in Veterans Health Administration: creating a useful database.

PubMed

Weiss, Lizabeth M; Drake, Audrey

2007-01-01

An electronic database was developed for succession planning and placement of nursing leaders interested and ready, willing, and able to accept an assignment in a nursing leadership position. The tool is a 1-page form used to identify candidates for nursing leadership assignments. This tool has been deployed nationally, with access to the database restricted to nurse executives at every Veterans Health Administration facility for the purpose of entering the names of developed nurse leaders ready for a leadership assignment. The tool is easily accessed through the Veterans Health Administration Office of Nursing Service, and by limiting access to the nurse executive group, ensures candidates identified are qualified. Demographic information included on the survey tool includes the candidate's demographic information and other certifications/credentials. This completed information form is entered into a database from which a report can be generated, resulting in a listing of potential candidates to contact to supplement a local or Veterans Integrated Service Network wide position announcement. The data forms can be sorted by positions, areas of clinical or functional experience, training programs completed, and geographic preference. The forms can be edited or updated and/or added or deleted in the system as the need is identified. This tool allows facilities with limited internal candidates to have a resource with Department of Veterans Affairs prepared staff in which to seek additional candidates. It also provides a way for interested candidates to be considered for positions outside of their local geographic area.

Classroom Simulation of United Nations Conference on Climate Change

Hastings, D. W.

2009-12-01

Global climate change is widely recognized as the most important environmental problem today that requires complex, global solutions with international cooperation. Teaching the science of climate change is relatively simple compared to the challenges of determining solutions to this problem. It is important for students to learn that solutions do exist and that international negotiations are underway to achieve reductions. What are the (policy) solutions to this vexing problem, which countries should take responsibility, and specifically how can this be done? In the final week of an advanced undergraduate environmental science class: Global Environmental Change, students engage in a week-long classroom simulation of the annual United Nations Framework Convention on Climate Change Conference of the Parties (UNFCCC/COP). Small groups of students represent one nation that has a particular, and important, interest in the negotiations. Each group researches the positions their country has with respect to the negotiations, determines their possible allies, and who might have interests that are in conflict with their country. While NGOs such as environmental organizations and industry groups are not formally represented, I include some of these groups since they are influential and provide interesting insight into different interests. For simplicity, about 8-10 nations and NGOs are included. In preparation for the conference, students produce a background paper and draft resolution. At the end of the conference, they refine these documents to produce an updated position paper and resolution on how to mitigate global warming. Students are asked to focus on: 1. How much to change global greenhouse gas emissions over the next decade and over the next century; 2. How much of these emission reductions their country should be responsible for; 3. How will their country meet these goals? They must focus on whether and how to implement two mechanisms: a) Clean Development Mechanisms (specifically whether forests should be used as a carbon sink); and b) emissions trading. Informal negotiations (often at a local café) are included in an effort to make the process more realistic. Fact or Fiction? This exercise is largely on reality, but some of it will be fictitious. While I encourage students to base arguments and proposals on real, documented information I encourage them to develop creative and innovative proposals. This exercise relies on educational material and resources designed for Model United Nations simulations; numerous on-line resources are available for students. At the end of the exercise both science and non-science students have enjoyed immersing themselves in challenging questions that confronts all practitioners of climate policy. This approach gives traditional science students an opportunity to experience the challenges and problems associated with implementing policy solutions, and allows those with interests in policy to explore their interests in depth. Rather than a static, text-oriented approach, students engage in active learning, which is appropriate for this quickly evolving subject. Details of classroom logistics, assessment tools, and handouts will be provided.

Parallel and competitive processes in hierarchical analysis: perceptual grouping and encoding of closure.

PubMed

Han, S; Humphreys, G W; Chen, L

1999-10-01

The role of perceptual grouping and the encoding of closure of local elements in the processing of hierarchical patterns was studied. Experiments 1 and 2 showed a global advantage over the local level for 2 tasks involving the discrimination of orientation and closure, but there was a local advantage for the closure discrimination task relative to the orientation discrimination task. Experiment 3 showed a local precedence effect for the closure discrimination task when local element grouping was weakened by embedding the stimuli from Experiment 1 in a background made up of cross patterns. Experiments 4A and 4B found that dissimilarity of closure between the local elements of hierarchical stimuli and the background figures could facilitate the grouping of closed local elements and enhanced the perception of global structure. Experiment 5 showed that the advantage for detecting the closure of local elements in hierarchical analysis also held under divided- and selective-attention conditions. Results are consistent with the idea that grouping between local elements takes place in parallel and competes with the computation of closure of local elements in determining the selection between global and local levels of hierarchical patterns for response.

Recently there has been a growing interest in studying multiplex networks where individuals are structured in multiple network layers. Previous agent-based simulations of games on multiplex networks reveal rich dynamics arising from interdependency of interactions along each network layer, yet there is little known about analytical conditions for cooperation to evolve thereof. Here we aim to tackle this issue by calculating the evolutionary dynamics of cooperation in group-structured populations with two layers of interactions. In our model, an individual is engaged in two layers of group interactions simultaneously and uses unrelated strategies across layers. Evolutionary competition of individuals is determined by the total payoffs accrued from two layers of interactions. We also consider migration which allows individuals to move to a new group within each layer. An approach combining the coalescence theory with the theory of random walks is established to overcome the analytical difficulty upon local migration. We obtain the exact results for all “isotropic” migration patterns, particularly for migration tuned with varying ranges. When the two layers use one game, the optimal migration ranges are proved identical across layers and become smaller as the migration probability grows. PMID:26632251

It is well known that pressure causes profound changes in the properties of atoms and chemical bonding, leading to the formation of many unusual materials. Here we systematically explore all stable calcium carbides at pressures from ambient to 100 GPa using variable-composition evolutionary structure predictions. We find that Ca 5C 2, Ca 2C, Ca 3C 2, CaC, Ca 2C 3, and CaC 2 have stability fields on the phase diagram. Among these, Ca2C and Ca2C3 are successfully synthesized for the first time via high-pressure experiments with excellent structural correspondence to theoretical predictions. Of particular significance are the base-centered monoclinic phasemore » (space group C 2/m) of Ca 2C, a quasi-two-dimensional metal with layers of negatively charged calcium atoms, and the primitive monoclinic phase (space group P21/c) of CaC with zigzag C 4 groups. Interestingly, strong interstitial charge localization is found in the structure of R-3m-Ca 5C 2 with semimetallic behaviour.« less

Composite operator and condensate in the S U (N ) Yang-Mills theory with U (N -1 ) stability group

Recently, some reformulations of the Yang-Mills theory inspired by the Cho-Faddeev-Niemi decomposition have been developed in order to understand confinement from the viewpoint of the dual superconductivity. In this paper we focus on the reformulated S U (N ) Yang-Mills theory in the minimal option with U (N -1 ) stability group. Despite existing numerical simulations on the lattice we perform the perturbative analysis to one-loop level as a first step towards the nonperturbative analytical treatment. First, we give the Feynman rules and calculate all renormalization factors to obtain the standard renormalization group functions to one-loop level in light of the renormalizability of this theory. Then we introduce a mixed gluon-ghost composite operator of mass dimension 2 and show the Bechi-Rouet-Stora-Tyutin invariance and the multiplicative renormalizability. Armed with these results, we argue the existence of the mixed gluon-ghost condensate by means of the so-called local composite operator formalism, which leads to various interesting implications for confinement as shown in preceding works.

Non-compact Groups, Coherent States, Relativistic Wave Equations and the Harmonic Oscillator II: Physical and Geometrical Considerations

NASA Astrophysics Data System (ADS)

Cirilo-Lombardo, Diego Julio

2009-04-01

The physical meaning of the particularly simple non-degenerate supermetric, introduced in the previous part by the authors, is elucidated and the possible connection with processes of topological origin in high energy physics is analyzed and discussed. New possible mechanism of the localization of the fields in a particular sector of the supermanifold is proposed and the similarity and differences with a 5-dimensional warped model are shown. The relation with gauge theories of supergravity based in the OSP(1/4) group is explicitly given and the possible original action is presented. We also show that in this non-degenerate super-model the physic states, in contrast with the basic states, are observables and can be interpreted as tomographic projections or generalized representations of operators belonging to the metaplectic group Mp(2). The advantage of geometrical formulations based on non-degenerate super-manifolds over degenerate ones is pointed out and the description and the analysis of some interesting aspects of the simplest Riemannian superspaces are presented from the point of view of the possible vacuum solutions.

Lessons learned from recent geomagnetic disturbance model validation activities

2017-12-01

Due to concerns pertaining to geomagnetically induced current impact on ground-based infrastructure, there has been significantly elevated interest in applying models for local geomagnetic disturbance or "delta-B" predictions. Correspondingly there has been elevated need for testing the quality of the delta-B predictions generated by the modern empirical and physics-based models. To address this need, community-wide activities were launched under the GEM Challenge framework and one culmination of the activities was the validation and selection of models that were transitioned into operations at NOAA SWPC. The community-wide delta-B action is continued under the CCMC-facilitated International Forum for Space Weather Capabilities Assessment and its "Ground Magnetic Perturbations: dBdt, delta-B, GICs, FACs" working group. The new delta-B working group builds on the past experiences and expands the collaborations to cover the entire international space weather community. In this paper, we discuss the key lessons learned from the past delta-B validation exercises and lay out the path forward for building on those experience under the new delta-B working group.

Parametrization of local CR automorphisms by finite jets and applications

NASA Astrophysics Data System (ADS)

Lamel, Bernhard; Mir, Nordine

2007-04-01

For any real-analytic hypersurface Msubset {C}^N , which does not contain any complex-analytic subvariety of positive dimension, we show that for every point pin M the local real-analytic CR automorphisms of M fixing p can be parametrized real-analytically by their ell_p jets at p . As a direct application, we derive a Lie group structure for the topological group operatorname{Aut}(M,p) . Furthermore, we also show that the order ell_p of the jet space in which the group operatorname{Aut}(M,p) embeds can be chosen to depend upper-semicontinuously on p . As a first consequence, it follows that given any compact real-analytic hypersurface M in {C}^N , there exists an integer k depending only on M such that for every point pin M germs at p of CR diffeomorphisms mapping M into another real-analytic hypersurface in {C}^N are uniquely determined by their k -jet at that point. Another consequence is the following boundary version of H. Cartan's uniqueness theorem: given any bounded domain Ω with smooth real-analytic boundary, there exists an integer k depending only on partial Ω such that if H\\colon Ωto Ω is a proper holomorphic mapping extending smoothly up to partial Ω near some point pin partial Ω with the same k -jet at p with that of the identity mapping, then necessarily H=Id . Our parametrization theorem also holds for the stability group of any essentially finite minimal real-analytic CR manifold of arbitrary codimension. One of the new main tools developed in the paper, which may be of independent interest, is a parametrization theorem for invertible solutions of a certain kind of singular analytic equations, which roughly speaking consists of inverting certain families of parametrized maps with singularities.

To explore the views of school nurses regarding mental health problems in young people and their potential for engaging in mental health work with this client group. Mental health problems in children and young people are an important public health issue. Universal children's services play a key role in identifying and managing these problems and, while school nurses have an important function in this work, little is known about their views on this aspect of their role. A qualitative research design employing focus group methodology. School nurses (n = 33) were purposively sampled from four school nursing teams in two English cities for a series of focus groups. The focus group data were audio-recorded, transcribed and subsequently analysed using 'framework'. Four principal themes emerged from the data. In these themes, school nurses were found to value their involvement with the mental health of young people, recognising this as an important area of practice. Several obstacles to their work in this area were identified: heavy workloads, professional rivalries, a lack of confidence and limited education and training opportunities. The importance of support from local specialist mental health teams was emphasised. School nurses can be engaged in mental health work though, as public health specialists, their role should focus on health promotion, assessment, signposting and early intervention activities. To facilitate mental health work, school nurses are able to draw on established interpersonal skills and supportive networks; however, workload and a lack of confidence need to be managed and it is important that they are supported by constructive relationships with local specialist mental health teams. This study has implications for nurses and healthcare practitioners interested in enhancing the mental health of children and young people in school settings. © 2011 Blackwell Publishing Ltd.

Objective We hypothesized that compared to healthy controls, long-term abstinent substance dependent individuals (SDI) will differ in their effective connectivity between large-scale brain networks and demonstrate increased directional information from executive control to interoception-, reward-, and habit-related networks. In addition, using graph theory to compare network efficiencies we predicted decreased small-worldness in SDI compared to controls. Methods 50 SDI and 50 controls of similar sex and age completed psychological surveys and resting state fMRI. fMRI results were analyzed using group independent component analysis; 14 networks-of-interest (NOI) were selected using template matching to a canonical set of resting state networks. The number, direction, and strength of connections between NOI were analyzed with Granger Causality. Within-group thresholds were p<0.005 using a bootstrap permutation. Between group thresholds were p<0.05, FDR-corrected for multiple comparisons. NOI were correlated with behavioral measures, and group-level graph theory measures were compared. Results Compared to controls, SDI showed significantly greater Granger causal connectivity from right executive control network (RECN) to dorsal default mode network (dDMN) and from dDMN to basal ganglia network (BGN). RECN was negatively correlated with impulsivity, behavioral approach, and negative affect; dDMN was positively correlated with impulsivity. Among the 14 NOI, SDI showed greater bidirectional connectivity; controls showed more unidirectional connectivity. SDI demonstrated greater global efficiency and lower local efficiency. Conclusions Increased effective connectivity in long-term abstinent drug users may reflect improved cognitive control over habit and reward processes. Higher global and lower local efficiency across all networks in SDI compared to controls may reflect connectivity changes associated with drug dependence or remission and requires future, longitudinal studies to confirm.

H II regions in the dwarf galaxy UGC-A 86

Miller, Bryan W.; Hodge, Paul

1993-01-01

The uncertain nature of the dwarf irregular galaxy UGC-A 86 (VIIZw009) makes it a very interesting object for studying star formation at the low end of the galaxy luminosity function. Saha and Hoessel (1991) find that this object is composed of two main parts, one of which appears more resolved than the other. The more resolved component has an excess of blue stars, suggesting that it is currently undergoing star formation. Thus, they argue that UGC-A 86 could be either a superposition of unrelated galaxies, two interacting galaxies, or a single galaxy. However, surface photometry performed by Richter et al. (1991) indicates that it is a single galaxy with an exponential luminosity profile. Richter et al. also find UGC-A 86 to be extremely dusty and to be associated with the infrared source IRAS 3550+6657. The uncertainty is compounded by the large ambiguity in the distance, though a heliocentric H1 velocity of 80 plus or minus 7 km s(sup -1) suggests that it is either a member of the Local Group or perhaps the IC 342 group. A distance of 1.5 Mpc and a reddening of E(B - V) = 0.65 is adopted. UGC-A 86 in H-alpha was observed in order to measure its current star formation rate. This is part of a larger project to study the star formation rates and histories of a complete sample of dwarf galaxies in the Local Group and other nearby groups. The H region luminosity function and size distribution for UGC-A 86 are presented and compared with previous observations of similar dwarf galaxies.

Characterizing the galaxy populations within different environments in the RCS2319 supercluster

NASA Astrophysics Data System (ADS)

Delahaye, Anna; Webb, Tracy

We present the results of a multi-wavelength photometric study of the high redshift supercluster RCS2319+00. RCS2319+00 is a high-redshift (z ~ 0.9) supercluster comprising three spectroscopically confrmed cluster cores discovered in the Red Sequence Cluster Survey (RCS) (Gladders & Yee 2005). Core proximities and merger rates estimate coalescence into a 1015 M ⊙ cluster by z ~ 0.5 (Gilbank et al. 2008). Spectroscopic studies of the system have revealed over 300 supercluster members located in the cores and several infalling groups (Faloon et al. 2013). RCS2319 presents a diverse range of dynamical systems and densities making it an ideal laboratory in which to study the effects of environment on galaxy properties. Imaging in optical and near infrared (griz' from MegaCam, JK s from WIRCam, both at CFHT), as well as 3.6 μm and 4.5μm from IRAC have enabled the assembly of a large photometric catalogue. Coupled with an extensive spectroscopic survey (Faloon et al. 2013) providing nearly 2400 redshifts across the field, photometric redshifts were determined using the template fitting code EAZY (Brammer et al. 2008). Nearly 80 000 photometric redshifts were measured providing a sample of nearly 3000 cluster members. To investigate effects of global environment, analysis was done utilizing a friend-of-friends group finding algorithm identifying several large and small infalling groups along with the three cluster cores. The cores are found to be dominated by massive, red galaxies and the field galaxies are populated by low mass, blue galaxies, as is the case in the local universe. Interestingly, the large groups exhibit intermediate properties between field and core populations, suggesting possible pre-processing as they are being accreted into the core halos. Relative fifth-nearest neighbour overdensity, log(1+δ5), is used as a proxy for local environment to investigate environmental dependence on galaxy colour. While there is an overall dependence of colour on local density, when controlled for stellar mass the dependence largely disappears. Indeed, galaxy mass is the dominant factor in determining colour, with local density a secondary effect only noticeable in lower mass galaxies at the 3 σ level for both colour and red fraction. RCS2319+00 presents a rare opportunity to probe many different densities and environments all located within the same object. We're able to investigate how galaxy evolution is affected by the environment, from field galaxies to infalling to groups to dense cluster cores, as well as the different density regions within each environment.

Psychiatry student interest groups: what they are and what they could be.

Reardon, Claudia L; Dottl, Susan; Krahn, Dean

Medical student interest groups across all specialties help students explore various specialties. There are no published reports on psychiatry student interest group (PSIG) curricula. The aim was to develop elements of a curriculum for such groups, based on data elicited from medical students and faculty members through a multi-institutional online survey. The authors electronically surveyed 172 United States psychiatric residency training directors to determine the activities they felt to be important for inclusion in PSIG curricula. Similarly, they surveyed U.S. medical student PSIG leaders to ascertain the activities they felt important to include in such groups, and the current content of their groups. Authors received responses from 64 program directors and 44 PSIG leaders. Based on integration of the results of both surveys, and the practices of existing groups, they propose elements of a curriculum for PSIGs. Medical student PSIG leaders are particularly interested in activities that involve residents. Other curricular topics of interest both to students and training directors include those that focus on student/physician mental health and various psychiatry subspecialties or practice settings. Training directors are willing to be involved with a wide variety of PSIG activities. The results of these surveys should help to guide PSIG leaders and faculty members in optimizing their PSIG curricula by helping them to include those activities felt to be of most interest by students and of most relevance by training directors.

To determine the effectiveness of three different local injection modalities in the treatment of lateral epicondilitis. In a prospective randomized study on lateral epicondilitis, 75 patients were divided into three equal groups A, B and C (n = 25) and were treated using three different method of local injection. The patients in group A were treated with local injection of a steroid (1 mL triamcinolone) combined with local anaesthetic (1 mL lidocaine), those in group B were treated with injection of local anaesthetic (1 mL lidocaine) combined with peppering technique and those in group C with local injection of a steroid (1 mL triamcinolone) combined with local anaesthetic (1 mL lidocaine) and peppering technique. The outcome was defined by measuring the elbow pain during the activity using a 10-cm visual analogue scale (VAS) and satisfaction with the treatment using a scoring system based on the criteria of the Verhaar et al. at 3 weeks and 6 months after the injection and compared with the pre-treatment condition. There were significant (P = 0.006) differences in the successful outcomes between the three groups at 6 months. In group C in which local steroid + peppering injection technique were used; excellent results were obtained in 84% of patients comparing to 36% and 48% for patients in groups A and B, respectively. The successful outcomes were statistically higher in group C comparing to group A (P = 0.002) and group B (P = 0.011). In all groups, there was a significantly lower pain (VAS) at the 3-week and 6-month follow-ups comparing to the pre-treatment condition. VAS measured at 6-month follow-up were significantly lower in group C comparing to other groups (P = 0.002). In the treatment of lateral epicondilitis, combination of corticosteroid injections with peppering is more effective than corticosteroid injections or peppering injections alone and produces better clinical results.

[Health councils, intergovernmental commissions, and interest groups in the Unified Health System

PubMed

Ribeiro

1997-01-01

Health councils have developed in Brazil in keeping with arrangements under the 1988 Constitution, and the logic of their political consensus has expanded among interest groups relevant to public policy. Collegiate bodies, such as intergovernmental commissions, represent an extension of that logic to executive relationships and also express political intermediation by expertise, following the tradition of the European Welfare State. The state technical bureaucracy has thus developed a remarkable role in policy-making and in State-level modeling of interest groups. This article argues that such collegiate bodies should be analyzed through State action and defines two models for health councils. One, the vocal political model, is characterized by a prevalence of outspoken denunciation and an overload of demands on the political agenda. The other, the consensus model, expresses self-limitation amongst interest groups in drafting demands. These models are not hierarchically fixed and are usually linked to the political platforms of interest groups participating in the collegiate bodies.

Closure of a local public hospital in Korea: focusing on the organizational life cycle

Just as living organisms have a creation-maintenance-extinction life cycle, organizations also have a life cycle. Private organizations will not survive if they fail to acquire necessary resources through market competition. Public organizations, however, continue to survive because the government has provided financial support in order to enhance public interest. Only a few public organizations in Korea have closed. With the introduction of new public management since the economic crisis in 1997, however, public organizations have had to compete with private organizations. Public hospitals are not free to open or close their business. They are also controlled by the government in terms of their prices, management, budgets, and operations. As they pursue public interest by fulfilling the government’s order such as providing free or lower-priced care to the vulnerable population, they tend to provide a lower quality of care and suffer a financial burden. Employing a case study analysis, this study attempts to understand the external environment that local public hospitals face. The fundamental problem of local public hospitals in Korea is the value conflict between public interest and profitability. Local public hospitals are required to pursue public interest by assignment of a public mission including building a medical safety net for low-income patients and managing nonprofitable medical facilities and emergent health care situations. At the same time, they are required to pursue profitability by achieving high-quality care through competition and the operation of an independent, self-supporting system according to private business logic. Under such paradoxical situations, a political decision may cause an unexpected result. PMID:29355194

To investigate medical students' career choice motivation and its relationship with their academic interest and performance. We conducted a cross-sectional study in a sample (n=207) of medical students at a private medical school in Korea, stratified by year of medical course. Data about participant demographics, career choice motivation and academic interest were collected using a self-report questionnaire. The item on career choice motivation enquired about the respondents' main reason for applying for medical school among 8 possible response options, which comprised two components of career choice motivation: intrinsic and extrinsic. The participants' levels of academic interest were measured in a Likert-type question. Participants' academic interest and Grade Point Averages (GPAs) were compared across the groups of different career motivations along with analyses of their admission scores for baseline comparisons. A total of 195 students completed the questionnaire (94%response rate). Seventy-four percent, (n=145; the intrinsic group) of the participants chose reasons related to intrinsic motivation, 22% (n=42; the extrinsic group) chose reasons pertaining to extrinsic motivation, and 4% (n = 8) chose other reasons for applying to medical school. The intrinsic group outperformed the extrinsic group in their GPAs, although their prior academic achievements did not differ significantly. The intrinsic group showed significantly higher levels of academic interest and also performed better in the admission interviews. Our study illustrates differences in medical students' academic interest and performance across career choice motivations. Further research is warranted to establish the predictive power of medical students' career choice motivation and academic interest on their academic performance.

Previous studies regarding the effects of some local anaesthetics have suggested that these agents can cause genetic damage. However, they have not been tested for genotoxicity related to repetitive administration. The aim of this study was to evaluate the genotoxic potential of local anaesthetics upon repetitive administration. 80 male Wistar rats were divided into: group A - 16 rats intraperitoneally injected with lidocaine hydrochloride 2%; group B - 16 rats IP injected with mepivacaine 2%; group C - 16 rats intraperitoneally injected with articaine 4%; group D - 16 rats IP injected with prilocaine 3% (6.0mg/kg); group E - 8 rats subcutaneously injected with a single dose of cyclophosphamide; and group F - 8 rats intraperitoneally injected with saline. Eight rats from groups A to D received a single dose of anaesthetic on Day 1 of the experiment; the remaining rats were dosed once a day for 5 days. The median number of micronuclei in the local anaesthetics groups exposed for 1 or 5 days ranged from 0.00 to 1.00, in the cyclophosphamide-exposed group was 10.00, and the negative control group for 1 and 5 days was 1.00 and 0.00, respectively (p<0.0001). A significant difference in the number of micronuclei was observed between the cyclophosphamide group and all local anaesthetic groups (p=0.0001), but not between the negative control group and the local anaesthetic groups (p>0.05). No genotoxicity effect was observed upon repetitive exposure to any of the local anaesthetics evaluated. Copyright © 2013 Sociedade Brasileira de Anestesiologia. Publicado por Elsevier Editora Ltda.

To investigate how local television news reported on health system reform during the week President Clinton presented his health system reform bill. Retrospective content analysis of the 1342-page Health Security Act of 1993, the printed text of President Clinton's speech before Congress on September 22, 1993, and a sample of local television news stories on health system reform broadcast during the week of September 19 through 25, 1993. The state of California. During the week, 316 television news stories on health system reform were aired during the 166 local news broadcasts sampled. Health system reform was the second most frequently reported topic, second to stories on violent crime. News stories on health system reform averaged 1 minute 38 seconds in length, compared with 57 seconds for violent crime. Fifty-seven percent of the local news stories focused on interest group politics. Compared with the content of the Health Security Act, local news broadcasts devoted a significantly greater portion of their stories to financing, eligibility, and preventive services. Local news stories gave significantly less attention to cost-saving mechanisms, long-term care benefits, and changes in Medicare and Medicaid, and less than 2% of stories mentioned quality assurance mechanisms, malpractice reform, or new public health initiatives. Of the 316 televised news stories, 53 reported on the president's speech, covering many of the same topics emphasized in the speech (financing, organization and administration, and eligibility) and de-emphasizing many of the same topics (Medicare and Medicaid, quality assurance, and malpractice reform). Two percent of the president's speech covered partisan politics; 45% of the local news stories on the speech featured challenges from partisan politicians. Although health system reform was the focus of a large number of local television news stories during the week, in-depth explanation was scarce. In general, the news stories provided superficial coverage framed largely in terms of the risks and costs of reform to specific stakeholders.
