Afterschool programs (ASPs) have potential to provide children moderate to vigorous physical activity (MVPA). The availability and types (e.g., free play or organized activities) of physical activity opportunities, their structure (e.g., presence of lines, elimination games), and staff behaviors (e.g., encouragement, engaged) can influence children's MVPA. This study explored these factors in 20 ASPs serving over 1,700 elementary-age children. The occurrence, types, and structure of physical activity opportunities, and staff behaviors were collected via the SOSPAN (System for Observing Staff Promotion of Physical Activity and Nutrition). A total of 4,660 SOSPAN scans were completed across 63 complete program days (1,733 during physical activity opportunities). Physical activity opportunities were observed on 60 program days across all 20 sites, with 73% of those opportunities classified as free play. ASPs scheduled an average of 66.3 minutes (range 15-150 minutes) of physical activity opportunities daily. Games played included basketball, tag, soccer, and football. Staff rarely engaged in physical activity promotion behaviors, and the structure of organized games discouraged MVPA. For example, staff verbally promoted physical activity in just 6.1% of scans, while organized games were more likely to involve lines and elimination. Professional development training may enhance staffs' physical activity promotion and the structure of activity opportunities. © 2015 Society for Public Health Education.

Career opportunities in clinical engineering.

PubMed

Morse, W A

1992-01-01

The varied career opportunities open to clinical engineers are described in this paper. Many of these opportunities are within the medical device industry in research, development, manufacturing design, regulatory activities, production, operations, sales, marketing, service, and management. Additional opportunities are available in hospitals, with the Veterans Administration, or working as an entrepreneur or a consultant. Each of these careers requires specific training and skills, and they all require a fundamental scientific knowledge of physical principles and mathematics. Research and management, however, require different educational preparation. The research emphasis should be on theoretical principles and creativity; the management emphasis should be on financial and labor problems. In all clinical engineering careers, the individual is a problem solver.

A narrative review of research on the effects of physical activity on people living with HIV and opportunities for health promotion in disadvantaged settings.

Ley, Clemens; Barrio, María Rato

2012-06-01

The article explores different types and effects of physical activity for people living with HIV. Considering the lack of studies done in African contexts and the disparity between research settings and natural settings, a narrative review of the literature was conducted and contextualised to South Africa. Various physical, psychological and social-cultural constraints impair the wellbeing of people living with HIV, in part by restricting their participation in physical activities. Apart from the well-studied immediate physiological benefits on health, we argue that physical-sportive group activities, such as sport or recreational games, can improve psychosocial factors and generate holistic health effects for people living with HIV. Group-activity effects could improve individuals' motivation and adherence to participating in physical activities, provided that positive interaction and non-stigmatisation are guaranteed. However, most studies in this field have been limited to the benefits of aerobic exercise and resistance training. There has been little research on the types and different effects of physical activity and adherence to physical activity of people living with HIV in African contexts. Based on an analysis of the different types and effects, we suggest opportunities for and challenges to implementing physical activities for people living with HIV, especially in disadvantaged settings, and also identify gaps in the research to date.

Fitzpatrick, Patricia, E-mail: p.fitzpatrick@uwinnipeg.c; Sinclair, A. John, E-mail: Jsincla@ms.umanitoba.c

This research examines complexities surrounding environmental impact assessment (EIA) in a multi-jurisdictional environment, with a specific focus on opportunities for public participation. With almost universal adoption of EIA, projects are increasingly subject to more than one assessment process. Thus there is demand to facilitate inter-jurisdictional coordination of EIAs. Canada has growing expertise with multijuristictional EIA that serves to illustrate the costs and opportunities associated with three different approaches to coordination: standardization, harmonization and substitution. Findings suggest that, although fraught with issues, harmonization is the most realistic approach for coordinating efforts. Harmonization has the potential to minimize duplication, avoid process uncertaintymore » and increase efficiency and effectiveness in EIA. Furthermore, the analysis demonstrates that a bilateral agreement between jurisdictions is the best approach to harmonization, so long as negotiation of the agreement includes opportunities for meaningful participation, and implementation includes activities designed to communicate the assessment responsibilities of each jurisdiction, activities and schedules to the public. The experience of participants of different coordinated EIAs in Canada serves as counsel for on-going and future efforts to facilitate inter-jurisdictional coordination.« less

Preschool settings vary greatly, and research has shown that interventions are more successful when they can be adapted to individual settings. This is a descriptive case study of how 2 teachers successfully adapted and implemented a preschool physical activity intervention. The Study of Health and Activity in Preschool Environments (SHAPES) was a 3-year physical activity intervention. A detailed case study of 2 high-implementing teachers was conducted. Multiple data sources included accelerometry, direct observation, teacher surveys, and intervention staff field notes. Teacher A focused on integrating physical activity into a wide range of activities, including parent and community events. Teacher B focused on high-intensity, structured activities. Both teachers supported the intervention, worked closely with intervention staff, and operated their classroom as an autonomous unit with support from their directors. Teacher A provided an average of 31.5, 78.0, and 67.5 min of physical activity opportunity per day of observation during years 1, 2, and 3. Teacher B provided an average of 2.7, 33.5, and 73.3 minutes of physical activity opportunity per day of observation. Successful implementation of physical activity interventions may look different in different contexts; thus, interventions should allow for flexible implementation. © 2015, American School Health Association.

Opportunities for market-based programs worldwide that reduce greenhouse gas emissions: Initial Observations from Missions to the Philippines, South Africa, and Mexico

Stanton-Hoyle, D.R.

1998-07-01

Globally, governments and industries are implementing innovative voluntary programs to reduce greenhouse gas emissions. Often these programs encourage groups to use cost effective technologies that capture market-based forces. These programs are successful because they capitalize on existing opportunities where both the environment and the participants can benefit (i.e., win-win opportunities). This paper documents efforts to investigate these kinds of win-win opportunities in three developing countries: the Philippines, South Africa, and Mexico. Initial observations are provided as fresh information from the field, drawing on six missions during the last nine months. Utility costs, interest rates, and overall economic health appear tomore » critically affect opportunities in each country. By contrast, details of heating, ventilating and air-conditioning (HVAC) design and local climate were often important differences between countries. These affect opportunities, for example, to achieve significant savings from cooling systems or not. Looking at the success of ESCOs was somewhat surprising. One might expect to see the most successful ESCO activity where utility costs are high and upgrade opportunities are plentiful (such as in the Philippines). This was not the case, however, as research in the Philippines did not reveal even one active ESCO contract yet. Design practices for new construction were in need of the same thing that helps US design teams do a better job of energy-efficient design, better communications between design team members. Finally, industrial firms were doing a variety of EE upgrades in each country, but this level of activity was relatively small compared to what should be cost effective.« less

Automatic honesty forgoing reward acquisition and punishment avoidance: a functional MRI investigation

2017-01-01

Recent neuroimaging investigations into human honesty suggest that honest moral decisions in individuals who consistently behave honestly occur automatically, without the need for active self-control. However, it remains unclear whether this observation can be applied to two different types of honesty: honesty forgoing dishonest reward acquisition and honesty forgoing dishonest punishment avoidance. To address this issue, a functional MRI study, using an incentivized prediction task in which participants were confronted with real and repeated opportunities for dishonest gain leading to reward acquisition and punishment avoidance, was conducted. Behavioral data revealed that the frequency of dishonesty was equivalent between the opportunities for dishonest reward acquisition and for punishment avoidance. Reaction time data demonstrated that two types of honest decisions in the opportunity for dishonest reward acquisition and punishment avoidance required no additional cognitive control. Neuroimaging data revealed that honest decisions in the opportunity for dishonest reward acquisition and those for punishment avoidance required no additional control-related activity compared with a control condition in which no opportunity for dishonest behavior was given. These results suggest that honesty flows automatically, irrespective of the concomitant motivation for dishonesty leading to reward acquisition and punishment avoidance. PMID:28746066

While some planetary scientists have extensive experience sharing their science with audiences, many can benefit from guidance on giving presentations or conducting activities for students. The Lunar and Planetary Institute (LPI) provides resources and trainings to support planetary scientists in their communication efforts. Trainings have included sessions for students and early career scientists at conferences (providing opportunities for them to practice their delivery and receive feedback for their poster and oral presentations), as well as separate communication workshops on how to engage various audiences. LPI has similarly begun coaching planetary scientists to help them prepare their public presentations. LPI is also helping to connect different audiences and their requests for speakers to planetary scientists. Scientists have been key contributors in developing and conducting activities in LPI education and public events. LPI is currently working with scientists to identify and redesign short planetary science activities for scientists to use with different audiences. The activities will be tied to fundamental planetary science concepts, with basic materials and simple modifications to engage different ages and audience size and background. Input from the planetary science community on these efforts is welcome. Current results and resources, as well as future opportunities will be shared.

A majority of preschool-aged children spend a significant portion of every weekday in a preschool or child care setting, where they typically participate in limited physical activity. This study determined if an ecologic physical activity intervention in preschools increases children's moderate- to vigorous-intensity physical activity (MVPA). RCT, with preschool as the unit of randomization and analysis. Child physical activity was measured by accelerometry. Mixed model analysis of covariance with preschool as a random variable was used to test the effects of the intervention on physical activity in the total group and in sex-specific subgroups. Data were collected in 2008-2010 and analyzed in 2012-2014. Children in 4-year-olds' classrooms in 16 preschools, pair matched and assigned to intervention or control groups. The intervention focused on increasing children's physical activity by changing instructional practices. Researchers trained preschool teachers to engage children in physical activity during (1) structured, teacher-led physical activity opportunities in the classroom; (2) structured and unstructured physical activity opportunities at recess; and (3) physical activity integrated into pre-academic lessons. Research staff encouraged teachers to adapt the intervention to their classrooms. Minutes/hour of MVPA during the preschool day. In an analytic sample of 379 children (188 intervention, 191 control), those in the intervention schools engaged in significantly more MVPA than children in control schools (7.4 and 6.6 minutes/hour, respectively). This difference remained significant after adjusting for parent education and length of the school day (half versus full day). In the sex-specific analyses, the difference was significant for girls (6.8 vs 6.1 minutes/hour of MVPA, respectively) but not for boys (7.9 vs 7.2 minutes/hour, respectively). A flexible ecologic physical activity intervention that trains teachers to provide children with opportunities to be active throughout the school day increased MVPA in preschool children.

Engaging Axiology: Enabling MeaningfulTransdisciplinary Collaboration in Adapted Physical Activity.

PubMed

Peers, Danielle

2018-07-01

In this article, I explore the concept of axiology in the context of adapted physical activity research and analyze its connection to the more commonly discussed paradigmatic assumptions of epistemology and ontology. Following methodological scholars, I argue for an acknowledgment of the pivotal role that axiology already plays in adapted physical activity research and for the potential interdisciplinary and transdisciplinary opportunities that could be enabled by engaging with axiology in more explicit ways. I discuss a number of potential axiological gaps between the field of adapted physical activity and disability communities, arguing that such differences may undermine attempts at doing meaningful transdisciplinary research with such communities. I offer strategies for bridging these axiological gaps, encouraging us to work together in axiologically reflexive ways in order to increase meaningful opportunities for more people with disabilities to be engaged in the movement-based activities and communities of their choice.

Physical activity in light of affordances in outdoor environments: qualitative observation studies of 3-5 years olds in kindergarten.

PubMed

Bjørgen, Kathrine

2016-01-01

This article examines the characteristic of affordances of different outdoor environments, related to the influences of children's physical activity levels. Qualitative observation studies in a Norwegian kindergarten were conducted of 3- to 5-year-olds into the natural environment and in the kindergarten's outdoor area. An ecological approach was important from both an analytical and theoretical point of view, using concepts from Gibson's (The ecological approach to visual perception. Houghton Mifflin Company, Bosten, 1979) theory of affordances. The concepts of affordances in an environment can explain children's movement behaviour. The findings reveal that situations with high physical activity levels among the children are more often created in natural environments than in the kindergarten's outdoor environment. Natural environments offer potential qualities that are a catalyst for physical activity. The study shows that certain characteristic of the physical outdoor environment are important for children's opportunities and inspiration for physical active play. The findings also show that social possibilities and opportunities, human interactions, in the environment have the greatest influence on the duration and intensity of physically active play. The need for knowledge on physical and social opportunities in outdoor environments, educational practice and the content of outdoor time in kindergartens should be given greater attention.

Acoustic change detection algorithm using an FM radio

Goldman, Geoffrey H.; Wolfe, Owen

2012-06-01

The U.S. Army is interested in developing low-cost, low-power, non-line-of-sight sensors for monitoring human activity. One modality that is often overlooked is active acoustics using sources of opportunity such as speech or music. Active acoustics can be used to detect human activity by generating acoustic images of an area at different times, then testing for changes among the imagery. A change detection algorithm was developed to detect physical changes in a building, such as a door changing positions or a large box being moved using acoustics sources of opportunity. The algorithm is based on cross correlating the acoustic signal measured from two microphones. The performance of the algorithm was shown using data generated with a hand-held FM radio as a sound source and two microphones. The algorithm could detect a door being opened in a hallway.

Finding disturbances in on-farm biogas production.

PubMed

Antonio, Pereira-Querol Marco; Laura, Seppänen

2012-01-01

When implementing innovations, disturbances are very likely to take place. Disturbances are undesirable because they can lead to unwanted outcomes, such as economic losses and work overload to workers. However, they can be powerful opportunities for learning and re-designing innovations. Here, we will present activity theoretical tools for analyzing disturbances in a way that they could be used as learning opportunities. We illustrate the proposed tools by analyzing a disturbance that took place during the implementation of a project of biogas production. By interpreting the disturbance process with a network of activity systems, we found that on-farm disturbances were formed as ruptures, innovations and asynchronies originated in other activity systems. This finding suggests that disturbances are outcomes of the functioning of networks, rather than simple results of failure of individuals or technical devices. The proposed tools could be used in interventions to help practitioners and ergonomists to recognize the systemic and networked nature of problems, and therefore, realize that they may require the collaboration of actors from different activities. In this sense, disturbances may be turned into opportunities for learning and developing innovations. We conclude by discussing how the method could be used in ergonomic design and intervention.

A behavioral task with more opportunities for memory acquisition promotes the survival of new neurons in the adult dentate gyrus.

PubMed

Aasebø, Ida E J; Kasture, Ameya Sanjay; Passeggeri, Marzia; Tashiro, Ayumu

2018-05-09

It has been suggested that the dentate gyrus, particularly its new neurons generated via adult neurogenesis, is involved in memory acquisition and recall. Here, we trained rats in two types of Morris water maze tasks that are differentially associated with these two memory processes, and examined whether new neurons are differently affected by the two tasks performed during the second week of neuronal birth. Our results indicate that the task involving more opportunities to acquire new information better supports the survival of new neurons. Further, we assessed whether the two tasks differentially induce the expression of an immediate early gene, Zif268, which is known to be induced by neuronal activation. While the two tasks differentially induce Zif268 expression in the dentate gyrus, the proportions of new neurons activated were similar between the two tasks. Thus, we conclude that while the two tasks differentially activate the dentate gyrus, the task involving more opportunities for memory acquisition during the second week of the birth of new neurons better promotes the survival of the new neurons.

This paper discusses the association between the morphology of tree planting in urban riverside brown field and user activities. With the growth of popularity, the revitalisation of urban public space is also promising. This research used drone photography and mapping to systematically surveys sample sites. An original observation study of user activities proceed in four sample public spaces in Sheffield. The study results found there are huge popularity and duration difference of user activities between various tree planting morphologies and typologies. The public space with lawn and rounded by mature trees attracted most users with the most activity types; the neat and silent public space is the favourite choice of lunch and reading, meanwhile it got the longest activity duration; but the space with sparse morphology and small trees are more likely be forgotten and abandoned. This finding offered a great opportunity for urban public space revitalisation in post-industrial cities.

The informal network 'Active Learning in Engineering Education' (ALE) has been promoting Active Learning since 2001. ALE creates opportunity for practitioners and researchers of engineering education to collaboratively learn how to foster learning of engineering students. The activities in ALE are centred on the vision that learners construct their knowledge based on meaningful activities and knowledge. In 2014, the steering committee of the ALE network reinforced the need to discuss the meaning of Active Learning and that was the base for this proposal for a special issue. More than 40 submissions were reviewed by the European Journal of Engineering Education community and this theme issue ended up with eight contributions, which are different both in their research and Active Learning approaches. These different Active Learning approaches are aligned with the different approaches that can be increasingly found in indexed journals.

Different preferences or different opportunities? Explaining race differentials in the academic achievement of friends

PubMed Central

Flashman, Jennifer

2015-01-01

A popular explanation for race and ethnic disparities in academic achievement is that minorities are exposed to different peers and have different opportunities to make friends with high-achievers. Although we know that adolescents from different race and ethnic groups attend different schools and that they choose different friends, we do not know how these different opportunities affect the friends they make. This paper fills this gap by studying how the opportunities within adolescents’ schools affect race and ethnic differences in the academic characteristics of friends. Using data from the National Longitudinal Study of Adolescent Health and the conditional logit and opportunities framework, I account for adolescents’ different opportunities to make friends both within and across schools. Ignoring their different opportunities, Black and Latino adolescents’ nominated friends have significantly lower levels of achievement than white adolescents. After accounting for their different opportunities to make friends within and between schools, race and ethnic differences in the achievement characteristics of friends disappear. If Black and Latino adolescents’ opportunity structures were identical to white adolescents’, their probabilities of nominating high-achieving friends would not differ. PMID:23017858

We investigate cultural and structural sources of class differences in youth activity participation with interview, survey, and archival data. We find working- and middle-class parents overlap in parenting logics about participation, though differ in one respect: middle-class parents are concerned with customizing children's involvement in activities, while working-class parents are concerned with achieving safety and social mobility for children through participation. Second, because of financial constraints, working-class families rely on social institutions for participation opportunities, but few are available. Schools act as an equalizing institution by offering low-cost activities, allowing working-class children to resemble middle-class youth in school activities, but they remain disadvantaged in out-of-school activities. School influences are complex, however, as they also contribute to class differences by offering different activities to working- and middle-class youth. Findings raise questions about the extent to which differences in participation reflect class culture rather than the objective realities parents face.

2008-01-01

Background: Interactive video games are a popular alternative to physical activity in youth. One advancement in computer games are interactive games that use physical activity as a game playing controller, combining exercise and entertainment, or exertainment. Purpose: This study tested the reinforcing value and activity levels of interactive dance and bicycle race games in 18 overweight and 17 nonoverweight 8- to 12-year-old youth. Methods: Reinforcing value was studied using a behavioral choice paradigm that provided children the opportunity to respond on progressive ratio schedules of reinforcement for a choice of either playing the video dance or bicycle game using a handheld video game controller or one of three options: dancing or bicycling alone, dancing or bicycling while watching a video, or playing the interactive dance or bicycle game. Reinforcing value was defined in relationship to the amount of responding children engaged in for either choice. Results: Results showed the interactive dance game was more reinforcing than dancing alone or dancing while watching the video (p = .003), but there was no difference across bicycling conditions. Nonoverweight youth were more active when given the opportunity to play the interactive dance game than overweight children (p = .05). Conclusions: These results suggest that children may be motivated to be active when given the opportunity to play an interactive dance game. PMID:17447864

F-BOX proteins in cancer cachexia and muscle wasting: emerging regulators and therapeutic opportunities

PubMed Central

Sukari, Ammar; Muqbil, Irfana; Mohammad, Ramzi M.; Philip, Philip A.; Azmi, Asfar S.

2016-01-01

Cancer cachexia is a debilitating metabolic syndrome accounting for fatigue, an impairment of normal activities, loss of muscle mass associated with body weight loss eventually leading to death in majority of patients with advanced disease. Cachexia patients undergoing skeletal muscle atrophy show consistent activation of the SCF ubiquitin ligase (F-BOX) family member Atrogin-1 (also known as MAFBx/FBXO32) alongside the activation of the muscle ring finger protein1 (MuRF1). Other lesser known F-BOX family members are also emerging as key players supporting muscle wasting pathways. Recent work highlights a spectrum of different cancer signaling mechanisms impacting F-BOX family members that feed forward muscle atrophy related genes during cachexia. These novel players provide unique opportunities to block cachexia induced skeletal muscle atrophy by therapeutically targeting the SCF protein ligases. Conversely, strategies that induce the production of proteins may be helpful to counter the effects of these F-BOX proteins. Through this review, we bring forward some novel targets that promote atrogin-1 signaling in cachexia and muscle wasting and highlight newer therapeutic opportunities that can help in the better management of patients with this devastating and fatal disorder.

The aim of this study was to develop an observer-rated measure of aesthetic, physical, social, and opportunity-related qualities of leisure activity settings for young people (with or without disabilities). Eighty questionnaires were completed by sets of raters who independently rated 22 community/home activity settings. The scales of the 32-item Measure of Environmental Qualities of Activity Settings (MEQAS; Opportunities for Social Activities, Opportunities for Physical Activities, Pleasant Physical Environment, Opportunities for Choice, Opportunities for Personal Growth, and Opportunities to Interact with Adults) were determined using principal components analyses. Test-retest reliability was determined for eight activity settings, rated twice (4-6wk interval) by a trained rater. The factor structure accounted for 80% of the variance. The Kaiser-Meyer-Olkin Measure of Sampling Adequacy was 0.73. Cronbach's alphas for the scales ranged from 0.76 to 0.96, and interrater reliabilities (ICCs) ranged from 0.60 to 0.93. Test-retest reliabilities ranged from 0.70 to 0.90. Results suggest that the MEQAS has a sound factor structure and preliminary evidence of internal consistency, interrater, and test-retest reliability. The MEQAS is the first observer-completed measure of environmental qualities of activity settings. The MEQAS allows researchers to assess comprehensively qualities and affordances of activity settings, and can be used to design and assess environmental qualities of programs for young people. © 2014 Mac Keith Press.

Objective To enumerate global health training activities in U.S. obstetrics and gynecology residency programs, and to examine the worldwide distribution of programmatic activity relative to the maternal and perinatal disease burden. Methods Using a systematic, Web-based protocol, we searched for global health training opportunities at all U.S. obstetrics and gynecology residency programs. Country-level data on disability-adjusted life years due to maternal and perinatal conditions were obtained from the Global Burden of Disease study. We calculated Spearman’s rank correlation coefficients to estimate the cross-country association between programmatic activity and disease burden. Results Of the 243 accredited U.S. obstetrics and gynecology residency programs, we identified 41 (17%) with one of several possible predefined categories of programmatic activity. Thirty-three residency programs offered their residents opportunities to participate in one or more elective-based rotations, eight offered extended field-based training, and 18 offered research activities. A total of 128 programmatic activities were dispersed across 64 different countries. At the country level, the number of programmatic activities had a statistically significant association with the total disease burden due to maternal (Spearman’s ρ=0.37; 95% confidence interval [CI], 0.14-0.57) and perinatal conditions (ρ=0.34; 95% CI, 0.10-0.54) but not gynecologic cancers (ρ=−0.24; 95% CI, −0.46 to 0.01). Conclusions There are few global health training opportunities for U.S. obstetrics and gynecology residents. These activities are disproportionately distributed among countries with greater burdens of disease. PMID:24104785

2017-07-01

Informal science learning has been found to have effects on students' science learning. Through the use of secondary data from a national assessment of 7410 middle school students in China, this study explores the relationship among five types of extracurricular science activities, learning interests, academic self-concept, and science achievement. Structural equation modelling was used to investigate the influence of students' self-chosen and school-organised extracurricular activities on science achievement through mediating interests and the academic self-concept. Chi-square tests were used to determine whether there was an opportunity gap in the student's engagement in extracurricular activities. The students' volunteer and school-organised participation in extracurricular science activities had a positive and indirect influence on their science achievement through the mediating variables of their learning interests and academic self-concept. However, there were opportunity gaps between different groups of students in terms of school location, family background, and especially the mother's education level. Students from urban areas with better-educated mothers or higher socioeconomic status are more likely to access diverse science-related extracurricular activities.

Donnelly, Lane F; Dorfman, Scott R; Jones, Jeremy; Bisset, George S

2017-10-18

To describe the process by which a radiology department moved from peer review to peer collaborative improvement (PCI) and review data from the first 16 months of the PCI process. Data from the first 16 months after PCI were reviewed: number of case reviews performed, number of learning opportunities identified, percentage yield of learning opportunities identified, type of learning opportunities identified, and comparison of the previous parameters between case randomly reviewed versus actively pushed (issues actively identified and entered). Changes in actively pushed cases were also assessed as volume per month over the 16 months (run chart). Faculty members were surveyed about their perception of the conversion to PCI. In all, 12,197 cases were peer reviewed, yielding 1,140 learning opportunities (9.34%). The most common types of learning opportunities for all reviewed cases included perception (5.1%) and reporting (1.9%). The yield of learning opportunities from actively pushed cases was 96.3% compared with 3.88% for randomly reviewed cases. The number of actively pushed cases per month increased over the course of the period and established two new confidence intervals. The faculty survey revealed that the faculty perceived the new PCI process as positive, nonpunitive, and focused on improvement. The study demonstrates that a switch to PCI is perceived as nonpunitive and associated with increased radiologist submission of learning opportunities. Active entering of identified learning opportunities had a greater yield and perceived value, compared with random review of cases. Copyright © 2017 American College of Radiology.

Urban environments offer students interesting opportunities to explore and examine how human modified landscapes influence biodiversity, nutrient cycling, and water quality. Students demanding applied field experiences from their undergraduate environmental science (ENVS) programs can be well served in urban settings. Here, we present strategies for integrating urban areas into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the intro level undergraduate ENVS class, we use our campus, the surrounding neighborhood and city as well as a nearby National Park for field exercises. Here we share lesson plans for field activities that can be completed with incoming undergraduate students, and show how these activities help students gain quantitative and investigative competency.

Marketing in home health care. A practical approach.

PubMed

Freitag, E M

1988-06-01

Home health marketing brings special problems and opportunities. One cannot rely on physical factors such as the physical plant and food service of a hospital or on the durability of a consumer product to judge home health. Opportunities exist within home health to identify activities that carry marketing value. Applying marketing principles to activities such as intake, customer service and public relations allows the home health agency to build referrals by meeting the wants and needs of the market. The home health organization needs to consider different wants and needs of those involved in the home health transaction: the decision maker, the purchaser, and the user. The success of the marketing function in meeting the organization's objectives will be aided by the placement of marketing at the senior management level.

Civic engagement and the transition to adulthood.

PubMed

Flanagan, Constance; Levine, Peter

2010-01-01

Constance Flanagan and Peter Levine survey research on civic engagement among U.S. adolescents and young adults. Civic engagement, they say, is important both for the functioning of democracies and for the growth and maturation it encourages in young adults, but opportunities for civic engagement are not evenly distributed by social class or race and ethnicity. Today's young adults, note the authors, are less likely than those in earlier generations to exhibit many important characteristics of citizenship, raising the question of whether these differences represent a decline or simply a delay in traditional adult patterns of civic engagement. Flanagan and Levine also briefly discuss the civic and political lives of immigrant youth in the United States, noting that because these youth make up a significant share of the current generation of young adults, their civic engagement is an important barometer of the future of democracy. The authors next survey differences in civic participation for youth from different social, racial, and ethnic backgrounds. They explore two sets of factors that contribute to a lower rate of civic engagement among low-income and minority young adults. The first is cumulative disadvantage-unequal opportunities and influences before adulthood, especially parental education. The second is different institutional opportunities for civic engagement among college and non-college youth during the young-adult years. Flanagan and Levine survey various settings where young adults spend time-schools and colleges, community organizations, faith-based institutions, community organizing and activism projects, and military and other voluntary service programs-and examine the opportunities for civic engagement that each affords. As the transition to adulthood has lengthened, say the authors, colleges have become perhaps the central institution for civic incorporation of younger generations. But no comparable institution exists for young adults who do not attend college. Opportunities for sustained civic engagement by year-long programs such as City Year could provide an alternative opportunity for civic engagement for young adults from disadvantaged families, allowing them to stay connected to mainstream opportunities and to adults who could mentor and guide their way.

Nature Elements and Fundamental Motor Skill Development Opportunities at Five Elementary School Districts in British Columbia

2017-01-01

The majority of Canadian children are not physically active enough for healthy development. School playgrounds are a primary location to promote physical activity and motor skill practice. The benefits of children’s play in nature have also been highlighted, but few studies have evaluated children’s access and exposure to nature for play on school grounds. This study examined children’s access to nature on school grounds and the opportunities afforded by those natural elements for motor skill practice. Results: Extensive naturescapes (multiple nature elements in one setting) were not common, and natural elements were limited, ranging from 1.97 to 5.71 elements/school. The most common element was a forested area (26.5% of all natural elements identified). In comparison to built structures, the number of natural elements was low. Some elements differed between school districts and appeared to be related to local geography and terrain (hilly, rocky terrain, tidal flats, etc.). Our assessment showed that naturescape elements afforded opportunities for the development of some key fundamental motor skills (FMS), specifically, locomotor and stability skills, but opportunities to develop manipulative skills were limited. To maximize potential FMS development, physical literacy, and psycho-social benefits, additional elements or more comprehensive multi-element naturescapes and facilitation (social or environmental) are recommended.

2016-01-01

Check-in records are usually available in social services, which offer us the opportunity to capture and analyze users’ spatial and temporal behaviors. Mining such behavior features is essential to social analysis and business intelligence. However, the complexity and incompleteness of check-in records bring challenges to achieve such a task. Different from the previous work on social behavior analysis, in this paper, we present a visual analytics system, Social Check-in Fingerprinting (Sci-Fin), to facilitate the analysis and visualization of social check-in data. We focus on three major components of user check-in data: location, activity, and profile. Visual fingerprints for location, activity, and profile are designed to intuitively represent the high-dimensional attributes. To visually mine and demonstrate the behavior features, we integrate WorldMapper and Voronoi Treemap into our glyph-like designs. Such visual fingerprint designs offer us the opportunity to summarize the interesting features and patterns from different check-in locations, activities and users (groups). We demonstrate the effectiveness and usability of our system by conducting extensive case studies on real check-in data collected from a popular microblogging service. Interesting findings are reported and discussed at last. PMID:27999398

The comparison of one-year recorded statistics on preembedded and postembedded activities demonstrated the effectiveness and impact of such an embedded librarian model.

Nursing electives: an innovative and creative learning opportunity.

PubMed

Peate, Ian

Nursing elective can provide the nurse (learner or registered nurse) with a host of new opportunities to experience and observe practice from a variety of different perspectives. The nursing elective should be planned well in advance and much time and thought should be given to preparing for this activity. There are a number of resources (human and material) available to help with the planning of the event and as such careful and thorough planning at an early stage can make the activity much more successful. The funding of the elective event needs to be thought about early on in the planning stage if this is likely to be an issue. Practical considerations, such as insurance cover, honorary contracts, travel and other documents must also be considered carefully. The elective opportunity has the potential to provide the individual with a unique experience, a chance to delve deeper in relation to a particular area of interest as well as potentially experiencing the provision of health care through an alternative lens. The success of the elective largely depends upon the amount of effort the individual puts into it.

Little is known about the association between environmental characteristics and types of physical activity in adolescents in a Latin American context. The aim of this study was to examine the association between perceived neighborhood environmental characteristics and different types of physical activity in 2,874 adolescents from Joao Pessoa, Paraiba State, Northeastern Brazil. The types of activity measured by questionnaire (≥10 min/day) included sports, physical exercises, active commuting and recreational activities. Neighborhood characteristics were measured by a 15-item scale. Multilevel analyses showed that adolescents who reported "having places they liked to go to" (OR = 1.41; 95%CI: 1.10-1.79) and "places with opportunities to practice" (OR = 1.29; 95%CI: 1.01-1.65) were more likely to play sports. "Seeing interesting things while walking" (OR = 1.24; 95%CI: 1.01-1.53) and "Seeing other adolescents engaged in physical activity" (OR = 1.47; 95%CI: 1,05-2,06) were associated with exercises. "Seeing other adolescents engaged in physical activity" (OR = 1.47; 95%CI: 1.18-1.82), "the neighborhood is not violent" (OR = 1.29; 95%CI: 1.04-1.60) and "having places they like to go to" (OR = 1.59; 95%CI: 1.13-2.25) were positively associated and "places with opportunities to practice" (OR = 0.79; 95%CI: 0.63-0.98) inversely related to active commuting. "Seeing other adolescents engaged in physical activities" (OR = 1.31; 95%CI: 1.05-1.63) and "seeing interesting things while walking" (OR = 1.26; 95%CI: 1.02-1.56) were associated with recreational activities. Neighborhood environmental characteristics associated with the physical activity vary with the type of practices adopted by adolescents.

Obesity during pregnancy is associated with increased risk of gestational diabetes mellitus (GDM) and other complications. Physical activity is a modifiable lifestyle factor that may help to prevent these complications but many women reduce their physical activity levels during pregnancy. Interventions targeting physical activity in pregnancy are on-going but few identify the underlying behaviour change mechanisms by which the intervention is expected to work. To enhance intervention effectiveness, recent tools in behavioural science such as the Theoretical Domains Framework (TDF) and COM-B model (capability, opportunity, motivation and behaviour) have been employed to understand behaviours for intervention development. Using these behaviour change methods, this study aimed to identify the enablers and barriers to physical activity in overweight and obese pregnant women. Semi-structured interviews were conducted with a purposive sample of overweight and obese women at different stages of pregnancy attending a public antenatal clinic in a large academic maternity hospital in Cork, Ireland. Interviews were recorded and transcribed into NVivo V.10 software. Data analysis followed the framework approach, drawing on the TDF and the COM-B model. Twenty one themes were identified and these mapped directly on to the COM-B model of behaviour change and ten of the TDF domains. Having the social opportunity to engage in physical activity was identified as an enabler; pregnant women suggested being active was easier when supported by their partners. Knowledge was a commonly reported barrier with women lacking information on safe activities during pregnancy and describing the information received from their midwife as 'limited'. Having the physical capability and physical opportunity to carry out physical activity were also identified as barriers; experiencing pain, a lack of time, having other children, and working prevented women from being active. A wide range of barriers and enablers were identified which influenced women's capability, motivation and opportunity to engage in physical activity with "knowledge" as the most commonly reported barrier. This study is a theoretical starting point in making a 'behavioural diagnoses' and the results will be used to inform the development of an intervention to increase physical activity levels among overweight and obese pregnant women.

F-BOX proteins in cancer cachexia and muscle wasting: Emerging regulators and therapeutic opportunities.

PubMed

Sukari, Ammar; Muqbil, Irfana; Mohammad, Ramzi M; Philip, Philip A; Azmi, Asfar S

2016-02-01

Cancer cachexia is a debilitating metabolic syndrome accounting for fatigue, an impairment of normal activities, loss of muscle mass associated with body weight loss eventually leading to death in majority of patients with advanced disease. Cachexia patients undergoing skeletal muscle atrophy show consistent activation of the SCF ubiquitin ligase (F-BOX) family member Atrogin-1 (also known as MAFBx/FBXO32) alongside the activation of the muscle ring finger protein1 (MuRF1). Other lesser known F-BOX family members are also emerging as key players supporting muscle wasting pathways. Recent work highlights a spectrum of different cancer signaling mechanisms impacting F-BOX family members that feed forward muscle atrophy related genes during cachexia. These novel players provide unique opportunities to block cachexia induced skeletal muscle atrophy by therapeutically targeting the SCF protein ligases. Conversely, strategies that induce the production of proteins may be helpful to counter the effects of these F-BOX proteins. Through this review, we bring forward some novel targets that promote atrogin-1 signaling in cachexia and muscle wasting and highlight newer therapeutic opportunities that can help in the better management of patients with this devastating and fatal disorder.

What Is Construed as Relevant Knowledge in Physics Teaching? Similarities and Differences in How Knowledge and Power Are Staged in Three Lower Secondary Classrooms

NASA Astrophysics Data System (ADS)

Lidar, Malena; Danielsson, Anna T.; Berge, Maria

2018-05-01

The content that is privileged in teaching has consequences for what the students are given the opportunity to learn and can thus be regarded as an aspect of power. We analyse power aspects in the teaching of physics by identifying actions that guide or direct other people's actions, and then analyse similarities and differences in different classrooms in terms of how governance is staged and what potential consequences this can have. The analyses are made on data from classroom activities, documented through video recordings and field notes, in three lower secondary schools in Y8 and Y9, respectively. At first glance, teachers from all three schools adhere to a traditional interpretation of a physics curriculum. But a more in-depth analysis shows that the students in the different classrooms are given quite dissimilar opportunities to participate in teaching and create relationships with the content. What appears to be a desirable way of acting offers different conditions for meaning-making. In an increasingly individualised society where people are expected to be active, reflective and make choices for their own personal good, the students in these three classrooms are offered very different conditions to practice and learn to take part in knowledge-making, connect physics content to their everyday life and exercise informed citizenship.

Internet of Things in Marketing: Opportunities and Security Issues

Abashidze, Irakli; Dąbrowski, Marcin

2016-12-01

Internet of Things (IoT) affects different areas of human activities: everyday life of ordinary citizens, work style of marketing teams, factories and even entire cities. Large companies try to implement the technology in their marketing strategy that reshapes not only communication style and product promotion but consumers' expectations, perceptions and requirements towards companies. IoT is expected to become a huge network that will encompass not only smart devices but significantly influence humans' behavior, in this particular case - decision making style in different phases of purchase process. Therefore, the need for comprehensive scientific research is necessary. The issue needs to be reviewed from various points of view, such as opportunities, advantages, disadvantages, legal and technical considerations. The paper is an attempt to review different aspects of using Internet of Things for marketing purposes, identify some of the major problems and present possible ways of solution.

Preschool-aged siblings of children with ASD are at high-risk (HR) for ASD and related challenges, but little is known about their emerging peer competence and friendships. Parents are the main providers of peer-relationship opportunities during preschool. Understanding parental challenges supporting early peer relationships is needed for optimal peer competence and friendships in children with ASD. We describe differences in peer relationships among three groups of preschool-aged children (15 HR-ASD, 53 HR-NonASD, 40 low-risk, LR), and examine parent support activities at home and arranging community-based peer activities. Children with ASD demonstrated precursors to poor peer competence and friendship outcomes. Parents in the HR group showed resilience in many areas, but providing peer opportunities for preschool-age children with ASD demanded significant adaptations.

2018-01-01

The Astronomy Department and McDonald Observatory at the University of Texas at Austin has and continues to offer a suite of different astronomy based K-12 teacher professional development programs. One of our longest running, and most successful programs, is reaching its 20th anniversary, the EXES Teacher Associate Program, which was started in 1998. The EXES Teacher Associate program features sustained and continued professional development opportunities for K-12 science and math educators. It consists of 6 times per year day-long meetings, coupled with other professional development opportunities provided at various times. In total, there are approximately 30 active members of the group currently, but more than 90 teachers have participated in this group over its 20 year history. The program has had astronomy education as its focus throughout its history, but different partnerships and collaborations with other programs have supported the group and have allowed for a variety of professional development opportunities and themes for educators to engage in. We will give an overview of this program, present evaluation data and teacher feedback related to program success and student impact, and highlight a few specific program opportunities that are unique and have been shown to be most impactful for participants.

What's wrong with hazard-ranking systems? An expository note.

PubMed

Cox, Louis Anthony Tony

2009-07-01

Two commonly recommended principles for allocating risk management resources to remediate uncertain hazards are: (1) select a subset to maximize risk-reduction benefits (e.g., maximize the von Neumann-Morgenstern expected utility of the selected risk-reducing activities), and (2) assign priorities to risk-reducing opportunities and then select activities from the top of the priority list down until no more can be afforded. When different activities create uncertain but correlated risk reductions, as is often the case in practice, then these principles are inconsistent: priority scoring and ranking fails to maximize risk-reduction benefits. Real-world risk priority scoring systems used in homeland security and terrorism risk assessment, environmental risk management, information system vulnerability rating, business risk matrices, and many other important applications do not exploit correlations among risk-reducing opportunities or optimally diversify risk-reducing investments. As a result, they generally make suboptimal risk management recommendations. Applying portfolio optimization methods instead of risk prioritization ranking, rating, or scoring methods can achieve greater risk-reduction value for resources spent.

Compound annotation with real time cellular activity profiles to improve drug discovery.

PubMed

Fang, Ye

2016-01-01

In the past decade, a range of innovative strategies have been developed to improve the productivity of pharmaceutical research and development. In particular, compound annotation, combined with informatics, has provided unprecedented opportunities for drug discovery. In this review, a literature search from 2000 to 2015 was conducted to provide an overview of the compound annotation approaches currently used in drug discovery. Based on this, a framework related to a compound annotation approach using real-time cellular activity profiles for probe, drug, and biology discovery is proposed. Compound annotation with chemical structure, drug-like properties, bioactivities, genome-wide effects, clinical phenotypes, and textural abstracts has received significant attention in early drug discovery. However, these annotations are mostly associated with endpoint results. Advances in assay techniques have made it possible to obtain real-time cellular activity profiles of drug molecules under different phenotypes, so it is possible to generate compound annotation with real-time cellular activity profiles. Combining compound annotation with informatics, such as similarity analysis, presents a good opportunity to improve the rate of discovery of novel drugs and probes, and enhance our understanding of the underlying biology.

An Analysis of NSF Geosciences 2009 Research Experience for Undergraduate Site Programs

NASA Astrophysics Data System (ADS)

Sanchez, S. C.; Patino, L. C.; Rom, E. L.; Weiler, S. C.

2009-12-01

The Research Experience for Undergraduate (REU) Program at the U.S. National Science Foundation (NSF) provides undergraduate students the opportunity to conduct research at different institutions and in areas that may not be available in their home campuses. The Geosciences REU Sites foster research opportunities in areas closely aligned with undergraduate majors and facilitates discovery of the multidisciplinary nature of the Geosciences. The aim of this paper is to provide an overview of the Geosciences REU Site programs run in 2009. A survey requesting information on recruitment methods, student demographics, enrichment activities, and fields of research was sent to the Principal Investigators of each of the 50 active REU Sites; over 70% of the surveys were returned with the requested information. The internet is the most widely used mechanism to recruit participants, but the survey did not distinguish among different tools like websites, emails, social networks, etc. The admissions rate for REU Sites in Geosciences varies from less than 10% to 50%, with the majority of participants being rising seniors and juniors. A few Sites include rising sophomores. At least 40% of the participants come from non-PhD granting institutions. Among the participants, gender distribution is balanced, with a slightly larger number of female participants. Regarding ethnic diversity, the REU Sites reflect the difficulty of attracting diverse students into Geosciences as a discipline; more than 75% of the participants are Caucasian and Asian students. Furthermore, participants from minority-serving institutions constitute a small percentage of those taking part in these research experiences. The enrichment activities are very similar across the REU Sites, and mimic well activities common to the scientific community, including intellectual exchange of ideas (lab meetings, seminars, and professional meetings), networking and social activities. There are some clear similarities among REU Sites managed by the three divisions in the Directorate of Geosciences (e.g. recruitment tools, academic level of participants, and enrichment activities), but other aspects vary among the Sites managed by the different divisions (e.g. admissions rate, diversity, and distribution among research disciplines). The results from this survey will be used to examine strengths in the REU Sites in the Geosciences, opportunities that may be under utilized, and community needs to enhance this NSF wide program.

The Relevance of Sex Differences in Performance Fatigability

PubMed Central

Hunter, Sandra K.

2016-01-01

Performance fatigability differs between men and women for a range of fatiguing tasks. Women are usually less fatigable than men and this is most widely described for isometric fatiguing contractions, and some dynamic tasks. The sex difference in fatigability is specific to the task demands so that one mechanism is not universal, including any sex differences in skeletal muscle physiology, muscle perfusion and voluntary activation. However, there are substantial knowledge gaps about the task dependency of the sex differences in fatigability, the involved mechanisms and the relevance to clinical populations and with advanced age. The knowledge gaps are in part due to the significant deficits in the number of women included in performance fatigability studies despite a gradual increase in the inclusion of women over the last 20 years. Therefore, this review 1) provides a rationale for the limited knowledge about sex differences in performance fatigability, 2) summarizes the current knowledge on sex differences in fatigability and the potential mechanisms across a range of tasks, 3) highlights emerging areas of opportunity in clinical populations, and 4) suggests strategies to close the knowledge gap and understanding the relevance of sex differences in performance fatigability. The limited understanding about sex differences in fatigability in healthy and clinical populations, presents as a field ripe with opportunity for high impact studies. Such studies will inform on the limitations of men and women during athletic endeavors, ergonomic tasks and daily activities. Because fatigability is required for effective neuromuscular adaptation, sex differences in fatigability studies will also inform on optimal strategies for training and rehabilitation in both men and women.

"Because I am Muslim, I cannot wear a swimsuit": Muslim girls negotiate participation opportunities for physical activity.

PubMed

Hamzeh, Manal; Oliver, Kimberly L

2012-06-01

Drawing on the works of postcolonial critical feminist and Arab Muslim feminist scholars, we discuss in this paper how 4 muslim girls (ages 14- 17 years) negotiated their participation in opportunities for physical activity. Data collection methods included self mapping questionnaires, digital photos, private journal entries, and recordings of informal conversations. We discuss (a) how three discursive challenges emerged in veiling-off opportunities for physical activity, and (b) how the girls uncovered alternative ways of being physically active. To promote active life practices with muslim girls, we need to (a) navigate the diversity of young muslims within the intersecting discourses in their lives that potentially challenge their participation in physical activities, and (b) honor young muslims' choices while negotiating their chances of maintaining physical activities.

The educational value of Disaster Victim Identification (DVI) missions-transfer of knowledge.

PubMed

Winskog, Calle; Tonkin, Anne; Byard, Roger W

2012-06-01

Transfer of knowledge is the cornerstone of any educational organisation, with senior staff expected to participate in the training of less experienced colleagues and students. Teaching in the field is, however, slightly different, and a less theoretical approach is usually recommended. In terms of Disaster Victim Identification (DVI) activities, practical work under supervision of a field team stimulates tactile memory. A more practical approach is also useful when multiple organizations from a variety of countries are involved, as language barriers make it easier to manually show someone how to solve a problem, instead of attempting to explain complex concepts verbally. "See one, do one, teach one" is an approach that can be used to ensure that teaching is undertaken with the teacher grasping the essentials of a situation before passing on the information to someone else. The key principles of adult learning that need to be applied to DVI situations include the following: participants need to know why they are learning and to be motivated to learn by the need to solve problems; previous experience must be respected and built upon and learning approaches should match participants' background and diversity; and finally participants need to be actively involved in the learning process. Active learning involves the active acquisition of knowledge and/or skills during the performance of a task and characterizes DVI activities. Learning about DVI structure, activities and responsibilities incorporates both the learning of facts ("declarative knowledge") and practical skills ("procedural knowledge"). A fundamental requirement of all DVI exercises should be succession planning with involvement of less experienced colleagues at every opportunity so that essential teaching and learning opportunities are maximized. DVI missions provide excellent teaching opportunities and international agencies have a responsibility to teach less experienced colleagues and local staff during deployment.

Assessing Brain–Muscle Connectivity in Human Locomotion through Mobile Brain/Body Imaging: Opportunities, Pitfalls, and Future Directions

PubMed Central

Gennaro, Federico; de Bruin, Eling D.

2018-01-01

Assessment of the cortical role during bipedalism has been a methodological challenge. While surface electroencephalography (EEG) is capable of non-invasively measuring cortical activity during human locomotion, it is associated with movement artifacts obscuring cerebral sources of activity. Recently, statistical methods based on blind source separation revealed potential for resolving this issue, by segregating non-cerebral/artifactual from cerebral sources of activity. This step marked a new opportunity for the investigation of the brains’ role while moving and was tagged mobile brain/body imaging (MoBI). This methodology involves simultaneous mobile recording of brain activity with several other body behavioral variables (e.g., muscle activity and kinematics), through wireless recording wearable devices/sensors. Notably, several MoBI studies using EEG–EMG approaches recently showed that the brain is functionally connected to the muscles and active throughout the whole gait cycle and, thus, rejecting the long-lasting idea of a solely spinal-driven bipedalism. However, MoBI and brain/muscle connectivity assessments during human locomotion are still in their fledgling state of investigation. Mobile brain/body imaging approaches hint toward promising opportunities; however, there are some remaining pitfalls that need to be resolved before considering their routine clinical use. This article discusses several of these pitfalls and proposes research to address them. Examples relate to the validity, reliability, and reproducibility of this method in ecologically valid scenarios and in different populations. Furthermore, whether brain/muscle connectivity within the MoBI framework represents a potential biomarker in neuromuscular syndromes where gait disturbances are evident (e.g., age-related sarcopenia) remains to be determined.

Light Activated Escape Circuits: A Behavior and Neurophysiology Lab Module using Drosophila Optogenetics

PubMed Central

Titlow, Josh S.; Johnson, Bruce R.; Pulver, Stefan R.

2015-01-01

The neural networks that control escape from predators often show very clear relationships between defined sensory inputs and stereotyped motor outputs. This feature provides unique opportunities for researchers, but it also provides novel opportunities for neuroscience educators. Here we introduce new teaching modules using adult Drosophila that have been engineered to express csChrimson, a red-light sensitive channelrhodopsin, in specific sets of neurons and muscles mediating visually guided escape behaviors. This lab module consists of both behavior and electrophysiology experiments that explore the neural basis of flight escape. Three preparations are described that demonstrate photo-activation of the giant fiber circuit and how to quantify these behaviors. One of the preparations is then used to acquire intracellular electrophysiology recordings from different flight muscles. The diversity of action potential waveforms and firing frequencies observed in the flight muscles make this a rich preparation to study the ionic basic of cellular excitability. By activating different cells within the giant fiber pathway we also demonstrate principles of synaptic transmission and neural circuits. Beyond conveying core neurobiological concepts it is also expected that using these cutting edge techniques will enhance student motivation and attitudes towards biological research. Data collected from students and educators who have been involved in development of the module are presented to support this notion. PMID:26240526

The role of emergency medicine clerkship e-Portfolio to monitor the learning experience of students in different settings: a prospective cohort study.

2018-04-12

Although emergency departments provide acute care learning opportunities for medical students, student exposure to recommended curriculum presentations and procedures are limited. In this perspective, clinical environments providing learning opportunities for students should be monitored as part of an ongoing quality improvement process. This study aims to analyze student exposures and their involvement levels in two different hospitals (Tawam and Al Ain) so as to improve the teaching and learning activities. This is a prospective study on all 76 final year medical students' electronic logbooks (e-Portfolio) of the academic year 2016/2017. Students recorded 5087 chief complaints and 3721 procedures. The average patient and procedure exposure in a shift per student in Al Ain Hospital compared with Tawam Hospital were 7.2 vs 6.4 and 5.8 vs 4.3, respectively. The highest full involvement with presentations was seen in the pediatric unit (67.1%, P < 0.0001). Urgent care shifts demonstrated the highest area of "full involvement" with procedures for our students (73.2%, P < 0.0001). Students' highest involvement with presentations and procedures were found during the night shifts (P < 0.0001, 66.5 and 75.1%, respectively). The electronic portfolio has proven to be a very useful tool in defining the learning activities of final year medical students during their emergency medicine clerkship and in comparing activities in two different clinical settings. Data collected and analyzed using this e-Portfolio has the potential to help medical educators and curriculum designers improve emergency medicine teaching and learning activities.

Beyond Watches and Chocolate-Global Mental Health Elective in Switzerland.

Schneeberger, Andres R; Weiss, Andrea; von Blumenthal, Suzanne; Lang, Undine E; Huber, Christian G; Schwartz, Bruce J

2016-08-01

Despite increasing interest in global mental health training opportunities, only a few psychiatry residency programs offer global mental health training experiences in developing countries and even fewer programs offer it in other first-world countries. The authors developed a global mental health elective giving US psychiatry residents the opportunity to visit Switzerland to study and experience the mental health care system in this European country. This elective focuses on four major learning objectives: (1) the system of training and curriculum of postgraduate psychiatry education in Switzerland, (2) clinical and organizational aspects of Swiss mental health, (3) administrative aspects of Swiss mental health care delivery, and (4) scholarly activity. This program was uniquely tailored for psychiatry residents. The preliminary experiences with US psychiatry residents show that they value this learning experience, the opportunity to access a different mental health care system, as well as the potential to build international connections with peers.

Are some health professionals more cognizant of clinical governance development concepts than others? Findings from a New Zealand study.

PubMed

Gauld, Robin; Horsburgh, Simon

2016-06-01

Clinical governance has been promoted in recent years as core to improving patient safety. Effective clinical governance requires partnerships between 'management' and health professionals as well as equal involvement of all professional groups. Professionals must also be willing to engage in clinical governance activities such as working to improve care systems and patient safety. There is limited research into the relative understanding of core clinical governance concepts amongst different professional groups or the extent to which professionals are prepared to take up opportunities to 'change the system'. A 2012 national survey study of health professionals employed in New Zealand health boards sought to probe understanding of and commitment to clinical governance following introduction of a 2009 policy. Respondent data showed only limited policy implementation had occurred. Regression analyses revealed statistically significant differences in perceptions of knowledge of clinical governance concepts and structures by gender, age, experience and profession, as well as in seeking opportunities to change the system. These findings have implications for policy makers in terms of ensuring that clinical governance implementation provides equal opportunity for engendering involvement of different health professionals. © The Author 2015.

The value of adaptive regret management in retirement.

PubMed

Farquhar, Jamie C; Wrosch, Carsten; Pushkar, Dolores; Li, Karen Z H

2013-01-01

This 3-year longitudinal study examined the associations between regret management, everyday activities, and retirement satisfaction among recent retirees. We hypothesized that the regulation of a severe life regret can facilitate activity engagement and retirement satisfaction, but only if retirees manage their regrets adaptively by either increasing effort and commitment when possessing favorable opportunities or disengaging when opportunity is unfavorable. Cross-sectional analyses demonstrated that the highest baseline levels of activity (e.g., volunteering, traveling) and retirement satisfaction were observed among participants who perceived favorable opportunities for addressing their life regrets and had high levels of engagement. Longitudinal analyses showed that this pattern was also associated with increases in activity engagement. In contrast, disengagement protected individuals with unfavorable opportunity from 3-year declines in retirement satisfaction. These findings indicate that adaptive regulation of regrets can both contribute to gains and prevent losses in the early stages of retirement, which may have lasting consequences on retirees' quality of life.

Career Issues and Laboratory Climates: Different Challenges and Opportunities for Women Engineers and Scientists (survey of Fiscal Year 1997 Powre Awardees)

NASA Astrophysics Data System (ADS)

Rosser, Sue V.; Zieseniss, Mireille

A survey of fiscal year 1997 POWRE (Professional Opportunities for Women in Research and Education) awardees from the National Science Foundation revealed that women engineers and scientists face similar issues, challenges, and opportunities and think that the laboratory climate has similar impacts on their careers. Separating responses of women scientists from those of women engineers revealed that 70% of both groups listed balancing work with family responsibilities as the most difficult issue. Discrepancies in percentages of women, coupled with differences among disciplinary and subdisciplinary cultures within science, engineering, mathematics, and technology fields, complicate work climates and their impact on women's careers. More frequently than women scientists, women engineers listed issues such as (a) low numbers of women leading to isolation, (b) lack of camaraderie and mentoring, (c) gaining credibility/respect from peers and administrators, (d) time management, (e) prioritizing responsibilities due to disproportionate demands, and (f) learning the rules of the game to survive in a male-dominated environment. Women engineers also listed two positive issues more frequently than women scientists: active recruitment/more opportunities for women and impact of successful women in the profession. The small number of women engineers may explain these results and suggests that it may be inappropriate to group them with other women scientists for analysis, programs, and policies.

Promoting youth physical activity in rural southern communities: practitioner perceptions of environmental opportunities and barriers.

PubMed

Edwards, Michael B; Theriault, Daniel S; Shores, Kindal A; Melton, Karen M

2014-01-01

Research on youth physical activity has focused on urban areas. Rural adolescents are more likely to be physically inactive than urban youth, contributing to higher risk of obesity and chronic diseases. Study objectives were to: (1) identify perceived opportunities and barriers to youth physical activity within a rural area and (2) identify rural community characteristics that facilitate or inhibit efforts to promote youth physical activity. Thirty in-depth interviews were conducted with expert informants in 2 rural southern US counties. Interviewees were recruited from diverse positions across multiple sectors based on their expert knowledge of community policies and programs for youth physical activity. Informants saw ball fields, natural amenities, and school sports as primary resources for youth physical activity, but they were divided on whether opportunities were abundant or scarce. Physical distance, social isolation, lack of community offerings, and transportation were identified as key barriers. Local social networks facilitated political action and volunteer recruitment to support programs. However, communities often lacked human capital to sustain initiatives. Racial divisions influenced perceptions of opportunities. Despite divisions, there were also examples of pooling resources to create and sustain physical activity opportunities. Developing partnerships and leveraging local resources may be essential to overcoming barriers for physical activity promotion in rural areas. Involvement of church leaders, school officials, health care workers, and cooperative extension is likely needed to establish and sustain youth rural physical activity programs. Allocating resources to existing community personnel and volunteers for continuing education may be valuable. © 2014 National Rural Health Association.

Altitudinal divergence in maternal thermoregulatory behaviour may be driven by differences in selection on offspring survival in a viviparous lizard.

PubMed

Uller, Tobias; While, Geoffrey M; Cadby, Chloe D; Harts, Anna; O'Connor, Katherine; Pen, Ido; Wapstra, Erik

2011-08-01

Plastic responses to temperature during embryonic development are common in ectotherms, but their evolutionary relevance is poorly understood. Using a combination of field and laboratory approaches, we demonstrate altitudinal divergence in the strength of effects of maternal thermal opportunity on offspring birth date and body mass in a live-bearing lizard (Niveoscincus ocellatus). Poor thermal opportunity decreased birth weight at low altitudes where selection on body mass was negligible. In contrast, there was no effect of maternal thermal opportunity on body mass at high altitudes where natural selection favored heavy offspring. The weaker effect of poor maternal thermal opportunity on offspring development at high altitude was accompanied by a more active thermoregulation and higher body temperature in highland females. This may suggest that passive effects of temperature on embryonic development have resulted in evolution of adaptive behavioral compensation for poor thermal opportunity at high altitudes, but that direct effects of maternal thermal environment are maintained at low altitudes because they are not selected against. More generally, we suggest that phenotypic effects of maternal thermal opportunity or incubation temperature in reptiles will most commonly reflect weak selection for canalization or selection on maternal strategies rather than adaptive plasticity to match postnatal environments. © 2011 The Author(s).

Strategy as active waiting.

Sull, Donald N

2005-09-01

Successful executives who cut their teeth in stable industries or in developed countries often stumble when they face more volatile markets. They falter, in part, because they assume they can gaze deep into the future and develop a long-term strategy that will confer a sustainable competitive advantage. But visibility into the future of volatile markets is sharply limited because so many different variables are in play. Factors such as technological innovation, customers' evolving needs, government policy, and changes in the capital markets interact with one another to create unexpected outcomes. Over the past six years, Donald Sull, an associate professor at London Business School, has led a research project examining some of the world's most volatile markets, from national markets like China and Brazil to industries like enterprise software, telecommunications, and airlines. One of the most striking findings from this research is the importance of taking action during comparative lulls in the storm. Huge business opportunities are relatively rare; they come along only once or twice in a decade. And, for the most part, companies can't manufacture those opportunities; changes in the external environment converge to make them happen. What managers can do is prepare for these golden opportunities by managing smart during the comparative calm of business as usual. During these periods of active waiting, leaders must probe the future and remain alert to anomalies that signal potential threats or opportunities; exercise restraint to preserve their war chests; and maintain discipline to keep the troops battle ready. When a golden opportunity or"sudden death"threat emerges, managers must have the courage to declare the main effort and concentrate resources to seize the moment.

Advantages and Limitations of Wearable Activity Trackers: Considerations for Patients and Clinicians.

PubMed

Walker, Rachel K; Hickey, Amanda M; Freedson, Patty S

2016-12-01

Exercise, light physical activity, and decreased sedentary time all have been associated with health benefits following cancer diagnoses. Commercially available wearable activity trackers may help patients monitor and self-manage their behaviors to achieve these benefits. This article highlights some advantages and limitations clinicians should be aware of when discussing the use of activity trackers with cancer survivors. Limited research has assessed the accuracy of commercially available activity trackers compared to research-grade devices. Because most devices use confidential, proprietary algorithms to convert accelerometry data to meaningful output like total steps, assessing whether these algorithms account for differences in gait abnormalities, functional limitations, and different body morphologies can be difficult. Quantification of sedentary behaviors and light physical activities present additional challenges. The global market for activity trackers is growing, which presents clinicians with a tremendous opportunity to incorporate these devices into clinical practice as tools to promote activity. This article highlights important considerations about tracker accuracy and usage by cancer survivors.

Prevalence of Physical Activity Policies and Environmental Strategies in Communities and Worksites: The Iowa Community Transformation Grant.

2016-01-01

This study describes results of community and worksite assessments of physical activity policies and environmental strategies in 26 Iowa counties. Community coalition members completed the Community Health Assessment and Group Evaluation tool. The study explored findings using descriptive statistics and examined rural-urban differences in two of the five assessed sectors: community and worksites. Lower community scores (ie, needing improvement) were found for complete streets, bicycle use, and street calming. Higher scores (ie, identified strengths) were found for land use plans, maintain parks, and sidewalks Americans with Disabilities Act compliant. Worksites scored lower on promote stairwells, encourage non-motorized commuting, and implement activity breaks but higher on subsidize gym membership and provide area for physical activity. No rural-urban differences were found. Results identify opportunities to enhance community and worksite policies and environmental strategies to increase physical activity.

Opportunities for involving men and families in chronic disease management: a qualitative study from Chiapas, Mexico.

Fort, Meredith P; Castro, Maricruz; Peña, Liz; López Hernández, Sergio Hernán; Arreola Camacho, Gabriel; Ramírez-Zea, Manuel; Martínez, Homero

2015-10-05

A healthy lifestyle intervention was implemented in primary care health centers in urban parts of Tuxtla Gutiérrez, Chiapas, Mexico with an aim of reducing cardiovascular disease risk for patients with type 2 diabetes and/or hypertension. During implementation, research questions emerged. Considerably fewer men participated in the intervention than women, and an opportunity was identified to increase the reach of activities aimed at improving disease self-management through strategies involving family members. A qualitative study was conducted to identify strategies to involve men and engage family members in disease management and risk reduction. Nine men with hypertension and/or type 2 diabetes with limited to no participation in disease self-management and health promotion activities, six families in which at least one family member had a diagnosis of one or both conditions, and nine health care providers from four different government health centers were recruited for the study. Participants took part in semi-structured interviews. During interviews with families, genograms and eco-maps were used to diagram family composition and structure, and capture the nature of patients' relationships to the extended family and community resources. Transcripts were coded and a general inductive analytic approach was used to identify themes related to men's limited participation in health promotion activities, family support and barriers to disease management, and health care providers' recommendations. Participants reported barriers to men's participation in chronic disease management and healthy lifestyle education activities that can be grouped into two categories: internal and external factors. Internal factors are those for which they are able to make the decision on their own and external factors are those that are not related solely to their decision to take part or not. Four primary aspects were identified related to families' relationships with disease: different roles within the family, types of support provided to patients, the opportunity to prevent disease among family members without a diagnosis, and - in some cases - lack of family support or stress-induced by other family members. There was an overlap in recommended strategies for engaging men and family members in chronic disease management activities. There is an opportunity to increase the reach of interventions aimed at improving disease self-management by engaging men and family members. The proposed strategies presented by patients, family members, and providers have implications for health education and service provision at primary care health centers and for future research.

Khare, Ritu; Good, Benjamin M.; Leaman, Robert; Su, Andrew I.

2016-01-01

The use of crowdsourcing to solve important but complex problems in biomedical and clinical sciences is growing and encompasses a wide variety of approaches. The crowd is diverse and includes online marketplace workers, health information seekers, science enthusiasts and domain experts. In this article, we review and highlight recent studies that use crowdsourcing to advance biomedicine. We classify these studies into two broad categories: (i) mining big data generated from a crowd (e.g. search logs) and (ii) active crowdsourcing via specific technical platforms, e.g. labor markets, wikis, scientific games and community challenges. Through describing each study in detail, we demonstrate the applicability of different methods in a variety of domains in biomedical research, including genomics, biocuration and clinical research. Furthermore, we discuss and highlight the strengths and limitations of different crowdsourcing platforms. Finally, we identify important emerging trends, opportunities and remaining challenges for future crowdsourcing research in biomedicine. PMID:25888696

Oceans of opportunity or rough seas? What does the future hold for developments in European marine policy?

PubMed

Potts, Tavis; O'Higgins, Tim; Hastings, Emily

2012-12-13

The management of European seas is undergoing a process of major reform. In the past, oceans and coastal policy has traditionally evolved in a fragmented and uncoordinated manner, developed by different sector-based agencies and arms of government with competing aims and objectives. Recently, the call for integrated and ecosystem-based approaches has driven the conceptualization of a new approach. At the scale of Europe through the Integrated Maritime Policy and Marine Strategy Framework Directive and in national jurisdictions such as the Marine and Coastal Access Act in the United Kingdom, ecosystem-based planning is becoming the norm. There are major challenges to this process and this paper explores, in particular, the opportunities inherent in building truly integrated approaches that cross different sectors of activity, integrate across scales, incorporate public involvement and build a sense of oceans citizenship.

Comparison of the Effectiveness of Interactive Didactic Lecture Versus Online Simulation-Based CME Programs Directed at Improving the Diagnostic Capabilities of Primary Care Practitioners.

PubMed

McFadden, Pam; Crim, Andrew

2016-01-01

Diagnostic errors in primary care contribute to increased morbidity and mortality, and billions in costs each year. Improvements in the way practicing physicians are taught so as to optimally perform differential diagnosis can increase patient safety and lower the costs of care. This study represents a comparison of the effectiveness of two approaches to CME training directed at improving the primary care practitioner's diagnostic capabilities against seven common and important causes of joint pain. Using a convenience sampling methodology, one group of primary care practitioners was trained by a traditional live, expert-led, multimedia-based training activity supplemented with interactive practice opportunities and feedback (control group). The second group was trained online with a multimedia-based training activity supplemented with interactive practice opportunities and feedback delivered by an artificial intelligence-driven simulation/tutor (treatment group). Before their respective instructional intervention, there were no significant differences in the diagnostic performance of the two groups against a battery of case vignettes presenting with joint pain. Using the same battery of case vignettes to assess postintervention diagnostic performance, there was a slight but not statistically significant improvement in the control group's diagnostic accuracy (P = .13). The treatment group, however, demonstrated a significant improvement in accuracy (P < .02; Cohen d, effect size = 0.79). These data indicate that within the context of a CME activity, a significant improvement in diagnostic accuracy can be achieved by the use of a web-delivered, multimedia-based instructional activity supplemented by practice opportunities and feedback delivered by an artificial intelligence-driven simulation/tutor.

Children's active free play in local neighborhoods: a behavioral mapping study.

PubMed

Veitch, J; Salmon, J; Ball, K

2008-10-01

Many Australian children are more sedentary than they should be, and almost one in five are currently overweight or obese. Some children may face difficulties finding opportunities to be active, having poor access to safe public open spaces or having low independent mobility limiting their access to places to play. This study aimed to examine children's access to places in their neighborhood for active free play and how these vary by age, sex and socioeconomic status (SES). Behavioral maps of the local neighborhood were completed by children (8-12 years) from five primary schools across different areas of Melbourne. Children living in low SES outer-urban neighborhoods had to travel greater distances to access local parks compared with those in inner-urban mid and high SES areas. One-third (32%) of children reported an independent mobility range of <100 m from home. In conclusion, for some children opportunities to engage in active free play in the local neighborhood may be limited due to lack of parks in close proximity to home and restricted independent mobility. It is important to collaborate with local governments, urban planners and community groups to improve access to neighborhood parks and to promote a sense of neighborhood safety.

Places and postures: A cross-cultural comparison of sitting in 5-month-olds

Motor development—traditionally described in terms of age-related stages—is typically studied in the laboratory with participants of Western European descent. Cross-cultural studies typically focus on group differences in age-related stages relative to Western norms. We adopted a less traditional approach: We observed 5-month-olds and their mothers from six cultural groups around the world during one hour at home while they engaged in natural daily activities. We examined group differences in infants’ sitting proficiency, everyday opportunities to practice sitting, the surfaces on which sitting took place, and mothers’ proximity to sitting infants. Infants had opportunities to practice sitting in varied contexts—including ground, infant chairs, and raised surfaces. Proficiency varied considerably within and between cultural groups: 64% of the sample sat only with support from mother or furniture and 36% sat independently. Some infants sat unsupported for 20+ minutes, in some cases so securely that mothers moved beyond arms’ reach of their infants even while infants sat on raised surfaces. Our observations of infant sitting across cultures provide new insights into the striking range of ability, varied opportunities for practice, and contextual factors that influence the proficiency of infant motor skills.

Interprofessional Education and Practice Guide No. 6: Developing practice-based interprofessional learning using a short placement model.

PubMed

Anderson, Elizabeth Susan; Ford, Jenny; Kinnair, Daniel James

2016-07-01

Offering undergraduate and post-qualified learners opportunities to take part in, and reflect on, the nature of interprofessional working when in practice remains an important goal for interprofessional educators. There are a plethora of opportunities within hospital and community care for learners to actively participate in health and social care delivery where collaborative practice prevails. However, it remains challenging to know how to establish and sustain meaningful interprofessional practice-based learning. This is because profession-specific teaching is prioritised and many teams are under-resourced, leaving little time for additional teaching activities. In some instances, practitioners lack the knowledge concerning how to design meaningful interprofessional learning and often feel unprepared for this teaching because of limited interprofessional faculty development. Others are simply unaware of the presence of the different students within their practice area. This guide offers key lessons developed over many years for setting up practice-based interprofessional education. The learning model has been adapted and adopted in different settings and countries and offers a method for engaging clinical front-line practitioners in learning with, and from learners who can help support and in some instances advance care delivery.

Implementation of interprofessional learning activities in a professional practicum: The emerging role of technology.

Brault, Isabelle; Therriault, Pierre-Yves; St-Denis, Louise; Lebel, Paule

2015-01-01

To prepare future healthcare professionals to collaborate effectively, many universities have developed interprofessional education programs (IPE). Till date, these programs have been mostly courses or clinical simulation experiences. Few attempts have been made to pursue IPE in healthcare clinical settings. This article presents the results of a pilot project in which interprofessional learning activities (ILAs) were implemented during students' professional practicum and discusses the actual and potential use of informatics in the ILA implementation. We conducted a pilot study in four healthcare settings. Our analysis is based on focus group interviews with trainees, clinical supervisors, ILA coordinators, and education managers. Overall, ILAs led to better clarification of roles and understanding of each professional's specific expertise. Informatics was helpful for developing a common language about IPE between trainees and healthcare professionals; opportunities for future application of informatics were noted. Our results support the relevance of ILAs and the value of promoting professional exchanges between students of different professions, both in academia and in the clinical setting. Informatics appears to offer opportunities for networking among students from different professions and for team members' professional development. The use of technology facilitated communication among the participants.

Contextual variations in costs for a community health strategy implemented in rural, peri-urban and nomadic sites in Kenya.

Wafula, Charles Ouma; Edwards, Nancy; Kaseje, Dan C O

2017-02-28

Many low and middle income countries have developed community health strategies involving lay health workers, to complement and strengthen public health services. This study explores variations in costing parameters pertinent to deployment of community health volunteers across different contexts outlining considerations for costing program scale-up. The study used quasi experimental study design and employed both quantitative and qualitative methods to explore community health unit implementation activities and costs and compare costs across purposively selected sites that differed socially, economically and ecologically. Data were collected from November 2010 to December 2013 through key informant interviews and focus group discussions. We interviewed 16 key informants (eight District community health strategy focal persons, eight frontline field officers), and eight focus group discussions (four with community health volunteers and four with community health committee) and 560 sets of monthly cost data. Cost data were tabulated using Microsoft Excel. Qualitative data were transcribed and coded using a content analysis framework. Four critical elements: attrition rates for community health volunteers, geography and population density, livelihood opportunity costs and benefits, and social opportunity benefits, drove cost variations across the three sites. Attrition rate was highest in peri-urban site where population is highly mobile and lowest in nomadic site. More households were covered by community health workers in the peri-urban area making per capita costs considerably less than in the nomadic settings where long distances had to be covered to reach sparsely distributed households. Livelihood opportunity costs for Community Health Volunteers were highest in nomadic setting, while peri-urban ones reported substantial employability benefits resulting from training. Social opportunity benefits were highest in rural site. Results show that costs of implementing community health strategy varied due to different area contextual factors in Kenya. This study identified four critical elements that drive cost variations: attrition rates for community health volunteers, geography and population density, livelihood opportunity costs and benefits, and social opportunity benefits. Health programme managers and policy-makers need to pay attention to details of contextual factors in costing for effective implementation of community health strategies.

Title IX, girls' sports participation, and adult female physical activity and weight.

PubMed

Kaestner, Robert; Xin Xu

2010-02-01

Arguably, the most important school-based intervention to increase physical activity was Title IX of the Education Amendments of 1972, which led to a 600% increase in girls' sports participation between 1972 and 1978. We studied the effect of this increase in sports participation and athletic opportunities while young on the physical activity and weight of adult women some 20-25 years later. Our results indicate that adult women who were affected by Title IX and had greater opportunity to participate in athletics while young had lower body mass index (BMI) and lower rates of obesity and reported being more physically active than women who were not afforded these opportunities. However, effect sizes were quite modest.

Exercising choice: the economic determinants of physical activity behaviour of an employed population.

PubMed

Brown, Heather; Roberts, Jennifer

2011-08-01

Lack of physical activity is a major contributing factor to the worldwide obesity epidemic, and to the overall burden of disease. The deindustrialisation of developed economies and move to more sedentary employment has impacted on the opportunities of working individuals to participate in physical activity. This can have negative effects on productivity and worker health potentially influencing economic growth. Thus, it is important to determine the factors influencing the frequency of participation in physical activity for employed individuals. This paper uses a modified time allocation framework to explore this issue. We use data from the first six waves of the Household Income and Labour Dynamics of Australia survey (HILDA). The analysis examines frequency of participation in physical activity using a generalised random effects ordered probit model. We control for non-parallel cut-points between the physical activity categories and individual heterogeneity, as well as exploring differences across gender. The results indicate that there is a time trade-off between non-market work, market work, and the frequency of physical activity participation. This effect is moderated by gender. For example, dependent children have a larger negative effect on the frequency of physical activity participation for women. Education and marriage have a larger negative effect on the frequency of participation for men. The findings suggests that policies which make exercise more convenient, and hence decrease the opportunity cost of exercise, will help to encourage more frequent participation in physical activity for working adults.

Healthy food choices and physical activity opportunities in two contrasting Alabama cities.

PubMed

Bovell-Benjamin, A C; Hathorn, C S; Ibrahim, S; Gichuhi, P N; Bromfield, E M

2009-06-01

Food and physical activity access and availability in two contrasting cities in Alabama were investigated. An in-outlet, observational, cross-sectional design was utilized to assess the opportunities for healthy food choices and physical activity. Thirty retail food outlets and 29 physical activity outlets were inventoried. None of the convenience stores carried frozen, low-sodium or dark-green, yellow vegetables, low-fat milk or yogurt, low-sodium and low-fat cheese, while none of the supermarkets in Tuskegee stocked low-sodium vegetables. In Tuskegee, the single public recreational area, which offered activities such as basketball, fees ranged from $25 to $35/month. Tuskegee has a shortage of "chain" supermarkets and a dominance of convenience stores which stocked few healthy foods. Overall, there are limited opportunities for healthy food and physical activity choices, which could be a barrier for chronic disease prevention efforts.

Behavioral and Psychological Phenotyping of Physical Activity and Sedentary Behavior: Implications for Weight Management.

PubMed

Bryan, Angela D; Jakicic, John M; Hunter, Christine M; Evans, Mary E; Yanovski, Susan Z; Epstein, Leonard H

2017-10-01

Risk for obesity is determined by a complex mix of genetics and lifetime exposures at multiple levels, from the metabolic milieu to psychosocial and environmental influences. These phenotypic differences underlie the variability in risk for obesity and response to weight management interventions, including differences in physical activity and sedentary behavior. As part of a broader effort focused on behavioral and psychological phenotyping in obesity research, the National Institutes of Health convened a multidisciplinary workshop to explore the state of the science in behavioral and psychological phenotyping in humans to explain individual differences in physical activity, both as a risk factor for obesity development and in response to activity-enhancing interventions. Understanding the behavioral and psychological phenotypes that contribute to differences in physical activity and sedentary behavior could allow for improved treatment matching and inform new targets for tailored, innovative, and effective weight management interventions. This summary provides the rationale for identifying psychological and behavioral phenotypes relevant to physical activity and identifies opportunities for future research to better understand, define, measure, and validate putative phenotypic factors and characterize emerging phenotypes that are empirically associated with initiation of physical activity, response to intervention, and sustained changes in physical activity. © 2017 The Obesity Society.

Extraterrestrial Virtual Field Experience: Water at Meridiani

NASA Astrophysics Data System (ADS)

Duggan-Haas, D.; Million, C.; Sullivan, R. J., Jr.; Hayes, A. G., Jr.; Ross, R. M.; St Clair, M.

2014-12-01

The Spacecraft Planetary Imaging Facility (SPIF) at Cornell University, in collaboration with Million Concepts and the Paleontological Research Institute (PRI), has developed the Extraterrestrial Virtual Field Experience (EVFE), a web-based, game-like and inquiry-driven classroom activity targeted to middle school through undergraduate introductory Earth science classrooms. Students play the role of mission scientists for a NASA rover mission, tasked with targeting the rover's scientific instruments to investigate a specific scientific question about the landing site. As with the real mission, the student operators must optimize the efficient use of limited resources and time against the need to make observations to address working hypotheses. The activity uses only real--not artificial or simulated--mission data, and students are guided throughout by a "Mission Manager" who provides hints and advice about the scientific meaning of observations within the broader context of the mission objectives. The MER Opportunity EVFE is a pilot effort, the first of five EVFE modules planned a rate of one per year that will feature different NASA missions and scientific topics. The MER Opportunity EVFE has already been developed and focuses on the investigation of the history of water on Mars at the Meridiani landing site of the Opportunity rover. The module includes a teacher guide and is currently available to educators through the SPIF website.

Disruptive change. When trying harder is part of the problem.

PubMed

Gilbert, Clark; Bower, Joseph L

2002-05-01

When a company faces a major disruption in its markets, managers' perceptions of the disruption influence how they respond to it. If, for instance, they view the disruption as a threat to their core business, managers tend to overreact, committing too many resources too quickly. But if they see it as an opportunity, they're likely to commit insufficient resources to its development. Clark Gilbert and Joseph Bower explain why thinking in such stark terms--threat or opportunity--is dangerous. It's possible, they argue, to arrive at an organizational framing that makes good use of the adrenaline a threat creates as well as of the creativity an opportunity affords. The authors claim that the most successful companies frame the challenge differently at different times: When resources are being allocated, managers see the disruptive innovation as a threat. But when the hard strategic work of discovering and responding to new markets begins, the disruptive innovation is treated as an opportunity. The ability to reframe the disruptive technology as circumstances evolve is not an easy skill to master, the authors admit. In fact, it might not be possible without adjusting the organizational structure and the processes governing new business funding. Successful companies, the authors have determined, tend to do certain things: They establish a new venture separate from the core business; they fund the venture in stages as markets emerge; they don't rely on employees from the core organization to staff the new business; and they appoint an active integrator to manage the tensions between the two organizations, to name a few. This article will help executives frame innovations in more balanced ways--allowing them to recognize threats but also to seize opportunities.

2015-01-01

To explore the experiences of children with cerebral palsy (CP) regarding participation in physical activities, and to describe facilitators and barriers. Sixteen children with CP 8-11 years old who varied in gross motor, cognitive and communicative function participated in either an individual interview or a focus group. Two categories and 10 sub-categories emerged from the content analysis. The category "Being physically active, because …" describes facilitators for being physically active divided into the sub-categories "Enjoying the feeling", "Being capable", "Feeling of togetherness", "Being aware it is good for me", and "Using available opportunities". The second category "Being physically active, but …" describes barriers to being physically active, divided into the sub-categories "Getting tired and experiencing pain", "Something being wrong with my body", "Being dependent on others", "Not being good enough" and "Missing available opportunities". Asking children with CP about the physical activities they enjoy, and giving them the opportunity of trying self-selected activities with the right support is important for facilitating an increased participation in physical activities. Having fun with family and friends when being physically active, and enjoying the sensation of speed should be taken into consideration when designing interventions. When supporting children to become and remain physically active, attention should be paid to pain, fatigue and the accessibility of activities and locations. Implications for Rehabilitation Children want to be physically active together with friends or others. Children want to have fun and enjoy the sensation of speed when being physically active. Self-selected physical activities and the opportunity of trying new activities with the right support is essential for facilitating an increased participation in physical activities. Service planning and design may be facilitated by asking children about the physical activities they enjoy.

Routine Language: Speech Directed to Infants During Home Activities.

Everyday activities are replete with contextual cues for infants to exploit in the service of learning words. Nelson's (1985) script theory guided the hypothesis that infants participate in a set of predictable activities over the course of a day that provide them with opportunities to hear unique language functions and forms. Mothers and their firstborn 13-month-old infants (N = 40) were video-recorded during everyday activities at home. Transcriptions and coding of mothers' speech to infants-time-locked to activities of feeding, grooming, booksharing, object play, and transition-revealed that the amount, diversity, pragmatic functions, and semantic content of maternal language systematically differed by activity. The activities of everyday life shape language inputs to infants in ways that highlight word meaning. © 2018 Society for Research in Child Development.

Knee cartilage segmentation using active shape models and local binary patterns

NASA Astrophysics Data System (ADS)

González, Germán.; Escalante-Ramírez, Boris

2014-05-01

Segmentation of knee cartilage has been useful for opportune diagnosis and treatment of osteoarthritis (OA). This paper presents a semiautomatic segmentation technique based on Active Shape Models (ASM) combined with Local Binary Patterns (LBP) and its approaches to describe the surrounding texture of femoral cartilage. The proposed technique is tested on a 16-image database of different patients and it is validated through Leave- One-Out method. We compare different segmentation techniques: ASM-LBP, ASM-medianLBP, and ASM proposed by Cootes. The ASM-LBP approaches are tested with different ratios to decide which of them describes the cartilage texture better. The results show that ASM-medianLBP has better performance than ASM-LBP and ASM. Furthermore, we add a routine which improves the robustness versus two principal problems: oversegmentation and initialization.

The Influence of Age-Related Differences in Prior Knowledge and Attentional Refreshing Opportunities on Episodic Memory.

PubMed

Loaiza, Vanessa M; Rhodes, Matthew G; Anglin, Julia

2015-09-01

The assumption that working memory (WM) is embedded within long-term memory suggests that the effectiveness of switching information between activated states in WM (i.e., attentional refreshing) may depend on whether that information is semantically relevant. Given that older adults often have greater general knowledge than younger adults, age-related deficits in episodic memory (EM) could be ameliorated by studying information that has existing semantic representations compared with unknown information. Younger and older adults completed a modified operation span task that varied the number of refreshing opportunities. The memoranda used were equally known to younger and older adults (neutral words; e.g., father), better known to older adults than younger adults (dated words; e.g., mirth), or unknown to both groups (unknown words; e.g., cobot). Results for immediate and delayed recall indicated an age-related improvement for dated memoranda and no age difference for unknown memoranda. Furthermore, refreshing opportunities predicted delayed recall of neutral memoranda more strongly for younger adults than older adults, whereas older adults' recall advantage for dated memoranda was explained by their prior knowledge and not refreshing opportunities. The results suggest that older adults' EM deficits could potentially be ameliorated by incorporating their superior knowledge to supplement relatively ineffective attentional refreshing in WM. © The Author 2013.

From the Paralympics to public health: increasing physical activity through legislative and policy initiatives.

PubMed

Blauwet, Cheri A; Iezzoni, Lisa I

2014-08-01

Individuals with disabilities experience a disproportionate rate of chronic disease and are more likely to lead sedentary lifestyles than the general population. Multiple complex factors likely contribute to these disparities, including structural, socioeconomic and attitudinal barriers that impede broad participation of individuals with disabilities in health and wellness promotion programs. Public health initiatives aimed at mitigating these health disparities emphasize improved access to physical activity and sports opportunities. Given its visibility, the Paralympic Movement provides an opportunity to transform how society conceptualizes the relationship of disability to physical fitness. The Paralympics also serve as a catalyst for public health education and program development. Already, public policies and governmental regulations are expanding grassroots sports opportunities for youth and adults with disabilities, thus promoting inclusive opportunities for participation in physical activity.

Edwards, Michael; Cunningham, George

2013-09-01

Racial health disparities are more pronounced among older adults. Few studies have examined how racism influences health behaviors. This study's purpose was to examine how opportunities for physical activity (PA) and community racism are associated with older racial minorities' reported engagement in PA. We also investigated how PA levels influenced health. We analyzed survey data obtained from a health assessment conducted in 3360 households in Texas, USA, which included items pertaining to PA, community characteristics, and health. Our sample contained 195 women and 85 men (mean age 70.16), most of whom were African American. We found no direct relationship between opportunities and PA. Results suggested that perceived community racism moderated this association. When community racism was low, respondents found ways to be active whether they perceived opportunities or not. When community racism was high, perceived lack of opportunities significantly impeded PA engagement. We found the expected association between PA and health. Results suggested that negative effects of community racism were counteracted through increased opportunities for PA.

Sex differences in opportunities to use alcohol or drugs, and transition to use, were investigated in 15 surveys, in 2001–2004 (Europe 6; Americas 3; Africa 2, Asia 3; Oceania 1). The paper focuses on 18–29 year olds (N = 9,873). The World Mental Health Survey Initiative oversaw the surveys; each country obtained its own funding. A complex picture emerged with different results for alcohol and for drugs and for opportunity to use and the transition to use. Sex differences in opportunity to use alcohol were small except in Lebanon and Nigeria, whereas for drugs, the largest differences were in Mexico and Colombia. PMID:21417555

Comparison of student outcomes and preferences in a traditional vs. World Wide Web-based baccalaureate nursing research course.

PubMed

Leasure, A R; Davis, L; Thievon, S L

2000-04-01

The purpose of this project was to compare student outcomes in an undergraduate research course taught using both World Wide Web-based distance learning technology and traditional pedagogy. Reasons given for enrolling in the traditional classroom section included the perception of increased opportunity for interaction, decreased opportunity to procrastinate, immediate feedback, and more meaningful learning activities. Reasons for selecting the Web group section included cost, convenience, and flexibility. Overall, there was no significant difference in examination scores between the two groups on the three multiple-choice examinations or for the course grades (t = -.96, P = .343). Students who reported that they were self-directed and had the ability to maintain their own pace and avoid procrastination were most suited to Web-based courses. The Web-based classes can help provide opportunities for methods of communication that are not traditionally nurtured in traditional classroom settings. Secondary benefits of the World Wide Web-based course were to increase student confidence with the computer, and introduce them to skills and opportunities they would not have had in the classroom. Additionally, over time and with practice, student's writing skills improved.

Explicit versus implicit motivations: Clarifying how experiences affect turkey hunter satisfaction using revised importance-performance, importance grid, and penalty-reward-contrast analyses

Schroeder, Susan A.; Cornicelli, Louis; Fulton, David C.; Merchant, Steven S.

2018-01-01

Although research has advanced methods for clarifying factors that relate to customer satisfaction, they have not been embraced by leisure researchers. Using results from a survey of wild turkey hunters, we applied traditional and revised importance-performance (IPA/RIPA), importance-grid analysis (IGA), and penalty-reward-contrast analysis (PRCA) to examine how activity-specific factors influenced satisfaction. Results suggested differences between the explicit and implicit importance of factors related to turkey hunting. Opportunities to kill turkeys were explicitly rated as less important than seeing, hearing, or calling in turkeys, but opportunities for harvest had relatively higher levels of implicit importance. PRCA identified “calling turkeys in” and “hearing gobbling” as minimum requirements that cause dissatisfaction if not fulfilled, but do not provide satisfaction, whereas “seeing turkeys” and an “opportunity to kill a turkey” related to both satisfaction and dissatisfaction. RIPA, IGA, and PRCA could provide valuable insights about factors that may improve satisfaction for leisure participants.

The Scientific and Engineering Student Internship (SESI) Program at NASA's GSFC

NASA Astrophysics Data System (ADS)

Bruhweiler, F.; Verner, E.; Rabin, D. M.

2011-12-01

Through our Scientific and Engineering Student Internship (SESI) program we have provided exceptional research opportunities for undergraduate and graduate students in one of the world's premier research centers dedicated to the Sun and its heliosphere, the Heliophysics Science Division at NASA/Goddard Space Flight Center. NASA/GSFC and the NSF/REU program have funded this activity jointly. These opportunities combine the advantages of the stimulating, multi-disciplinary, environment of a NASA laboratory with the guidance provided by researchers who are, in addition, committed to education and the encouragement of women, under-represented minorities, and students with disabilities. Opportunities also exist for non-U.S. citizens as well. Moreover, the surrounding Washington, DC area provides a variety of social and educational activities for our participating students. Our 19 years of experience has served as an effective catalyst, enabling us to establish a formal program for students interested in Solar and Space Physics at NASA and to develop more NASA-funded opportunities for students, in addition to those funded by NSF/REU awards. This has allowed us to present a combined NSF/REU and NASA-funded program for undergraduates at NASA/GSFC. This synergistic program exposes our student interns to a very wide range of projects and ideas, normally unavailable in other programs. We have had roughly 300 students (about 1/2 being supported by NSF) actively participate in over 200 different research opportunities. These research projects have spanned the spectrum, ranging from theoretical modeling associated with space weather, developing instrumentation for space missions, analysis of spacecraft data, including 'hands-on' experience with sounding rockets and working in the clean environs of GSFC's Detector Development Laboratory. Although SESI is largely a summer program, a number of students, often through other funding sources, continue their research projects during subsequent summers or in the academic year.

Objective The dramatic increase in papillary thyroid carcinoma (PTC) is primarily a result of early diagnosis of small cancers. Active surveillance is a promising management strategy for papillary thyroid microcarcinomas (PTMCs). However, as this management strategy gains traction in the U.S., it is imperative that patients and clinicians be properly educated, patients be followed for life, and appropriate tools be identified to implement the strategy. Methods We review previous active surveillance studies and the parameters used to identify patients who are good candidates for active surveillance. We also review some of the challenges to implementing active surveillance protocols in the U.S. and discuss how these might be addressed. Results Trials of active surveillance support nonsurgical management as a viable and safe management strategy. However, numerous challenges exist, including the need for adherence to protocols, education of patients and physicians, and awareness of the impact of this strategy on patient psychology and quality of life. The Thyroid Cancer Care Collaborative (TCCC) is a portable record keeping system that can manage a mobile patient population undergoing active surveillance. Conclusion With proper patient selection, organization, and patient support, active surveillance has the potential to be a long-term management strategy for select patients with PTMC. In order to address the challenges and opportunities for this approach to be successfully implemented in the U.S., it will be necessary to consider psychological and quality of life, cultural differences, and the patient’s clinical status.

Lenzi, Michela; Vieno, Alessio; Santinello, Massimo; Perkins, Douglas D

According to the norms and collective efficacy model, the levels of social connectedness within a local community are a function of neighborhood structural characteristics, such as socioeconomic status and ethnic composition. The current work aims to determine whether neighborhood structural and institutional features (neighborhood wealth, percentage of immigrants, population density, opportunities for activities and meeting places) have an impact on different components of neighborhood social connectedness (intergenerational closure, trust and reciprocity, neighborhood-based friendship and personal relationships with neighbors). The study involved a representative sample of 389 early and middle adolescents aged 11-15 years old, coming from 31 Italian neighborhoods. Using hierarchical linear modeling, our findings showed that high population density, ethnic diversity, and physical and social disorder might represent obstacles for the creation of social ties within the neighborhood. On the contrary, the presence of opportunities for activities and meeting places in the neighborhood was associated with higher levels of social connectedness among residents.

Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

Effects of Social versus Musical Antecedents on Communication Responsiveness in Five Children with Developmental Disabilities.

PubMed

Braithwaite; Sigafoos

1999-01-01

The present study involved a comparison of social versus musical antecedents on communication responsiveness in five children with developmental disabilities. During the social antecedent condition, the teacher presented opportunities for the children to greet, name objects, and request materials. In the musical antecedent condition, these same opportunities were embedded within a music/singing activity. A reversal design was used to compare the percentage of opportunities with appropriate communication responses across the two conditions. For three of the five children, the musical antecedent condition was associated with higher percentages of appropriate communication responses. For the other two children, the two conditions were associated with approximately equal rates of appropriate communication. Across both conditions, appropriate responses were more likely during opportunities for greeting and requesting than during opportunities to name objects. The results suggest that embedding communication opportunities within a musical activity may lead to increased appropriate communication responses for some children with developmental disabilities.

Vast amounts of bioactivity data have been generated for small molecules across public and corporate domains. Biological signatures, either derived from systematic profiling efforts or from existing historical assay data, have been successfully employed for small molecule mechanism-of-action elucidation, drug repositioning, hit expansion and screening subset design. This article reviews different types of biological descriptors and applications, and we demonstrate how biological data can outlive the original purpose or project for which it was generated. By comparing 150 HTS campaigns run at Novartis over the past decade on the basis of their active and inactive chemical matter, we highlight the opportunities and challenges associated with cross-project learning in drug discovery.

This study aimed to estimate the prevalence of physical activity in different domains and the association with schooling, using a serial cross-sectional population-based design comparing data from two editions of a health survey in the city of São Paulo, Brazil. Participation included 1,667 adults in 2003 and 2,086 in 2008. Probabilistic sampling was performed by two-stage clusters. The long version of International Physical Activity Questionnaire (IPAQ) allowed evaluating multiple domains of physical activity. Poisson regression was used. Men were more active in their leisure time and at work and women in the home. Schooling was associated directly with leisure-time activity (2003 and 2008) and inversely with work-related physical activity (2003) for men and for women in housework. The studies showed that Brazilians with less schooling are becoming less active, so that intervention strategies should consider different educational levels. Interventions in the urban space and transportation can increase the opportunities for physical activity and broaden access by the population.

2017-01-01

Researchers and practitioners are increasingly interested in entrepreneurship as a means to fight youth unemployment and to improve financial stability at higher ages. However, only few studies so far have examined the association between age and entrepreneurial activity. Based on theories from the lifespan psychology literature and entrepreneurship, we develop and test a model in which perceived opportunities and skills explain the relationship between age and entrepreneurial activity. We analyzed data from the 2013 Global Entrepreneurship Monitor (GEM), while controlling for gender and potential variation between countries. Results showed that age related negatively to entrepreneurial activity, and that perceived opportunities and skills for entrepreneurship mediated this relationship. Overall, these findings suggest that entrepreneurship research should treat age as a substantial variable.

The difference is more than floating: factors affecting breast cancer survivors' decisions to join and maintain participation in dragon boat teams and support groups.

Peer support can be helpful in rehabilitation from breast cancer, but participation in peer support groups is low. Groups that provide support opportunities in physical activity contexts are an attractive alternative for some survivors. This study examined survivors' reasons for joining and maintaining participation on a dragon boat team, along with perceptions of barriers and attractions to traditional peer support groups. Seventeen breast cancer survivors were interviewed on five occasions over their first two seasons of a newly formed dragon boating team to explore their perceptions of peer support groups and dragon boating. Data were inductively analyzed using thematic analysis. Categories surrounding physical, psychological, social and community features were identified with several themes emerging within each. Advantages of dragon boating included opportunities to get a combination of physical, psychosocial and community benefits; health improvement and behavior change; and obtaining social support without the focus being on cancer. Peer support groups were identified as having advantages for forming relationships and avoiding barriers associated with physical activity. While neither type of program meets all needs, practical considerations are identified for incorporating advantages of both programs to improve participation. Implications for rehabilitation Further understanding of perceptions, and attractions and challenges to taking part in group programs will inform development of accessible programs that target multiple rehabilitation needs. Physical activity can provide a positive, alternative focus that takes the emphasis off of cancer, which is more accessible to some survivors. Physical activity also provides opportunities to build relationships around a common, positive goal, which can be a foundation for providing support for coping with cancer.

Millions of children attend after-school programs in the United States. Increasing physical activity levels of program participants could have a broad effect on children's health. To test the effectiveness of the Out of School Nutrition and Physical Activity (OSNAP) Initiative in increasing children's physical activity levels in existing after-school programs. Cluster-randomized controlled trial with matched program pairs. Baseline data were collected September 27 through November 12, 2010, with follow-up data collected April 25 through May 27, 2011. The dates of our analysis were March 11, 2014, through August 18, 2015. The setting was 20 after-school programs in Boston, Massachusetts. All children 5 to 12 years old in participating programs were eligible for study inclusion. Ten programs participated in a series of three 3-hour learning collaborative workshops, with additional optional opportunities for training and technical assistance. Change in number of minutes and bouts of moderate to vigorous physical activity, vigorous physical activity, and sedentary activity and change in total accelerometer counts between baseline and follow-up. Participants with complete data were 402 racially/ethnically diverse children, with a mean age of 7.7 years. Change in the duration of physical activity opportunities offered to children during program time did not differ between conditions (-1.2 minutes; 95% CI, -14.2 to 12.4 minutes; P = .87). Change in moderate to vigorous physical activity minutes accumulated by children during program time did not differ significantly by intervention status (-1.0; 95% CI, -3.3 to 1.3; P = .40). Total minutes per day of vigorous physical activity (3.2; 95% CI, 1.8-4.7; P < .001), vigorous physical activity minutes in bouts (4.1; 95% CI, 2.7-5.6; P < .001), and total accelerometer counts per day (16,894; 95% CI, 5101-28,686; P = .01) increased significantly during program time among intervention participants compared with control participants. Although programs participating in the OSNAP Initiative did not allot significantly more time for physical activity, they successfully made existing time more vigorously active for children receiving the intervention. clinicaltrials.gov Identifier: NCT01396473.

Catalysis by metal-organic frameworks: fundamentals and opportunities.

PubMed

Ranocchiari, Marco; van Bokhoven, Jeroen Anton

2011-04-14

Crystalline porous materials are extremely important for developing catalytic systems with high scientific and industrial impact. Metal-organic frameworks (MOFs) show unique potential that still has to be fully exploited. This perspective summarizes the properties of MOFs with the aim to understand what are possible approaches to catalysis with these materials. We categorize three classes of MOF catalysts: (1) those with active site on the framework, (2) those with encapsulated active species, and (3) those with active sites attached through post-synthetic modification. We identify the tunable porosity, the ability to fine tune the structure of the active site and its environment, the presence of multiple active sites, and the opportunity to synthesize structures in which key-lock bonding of substrates occurs as the characteristics that distinguish MOFs from other materials. We experience a unique opportunity to imagine and design heterogeneous catalysts, which might catalyze reactions previously thought impossible.

Using storyboards to make your performance improvement plan come alive.

The key to successfully using storyboarding within the PI plan is to create a storyboard for each activity as it is completed. Our agency waited until JCAHO was almost upon us. The historical preservation of activities as they occur will create an archive of activities for your PI committee and staff as well as for surveyors. The storyboard's second purpose is the communication of activities to the staff. Take the opportunity to use the boards as educational activities for the staff. Performance Improvement can many times be a frightening, or at best frustrating and uncomfortable activity for staff personnel. Bringing the PI plan alive through the use of storyboards accomplishes many goals as well as helps all staff see how Performance Improvement really makes a difference.

An investigation of the practice of scientific inquiry in secondary science and agriculture courses

NASA Astrophysics Data System (ADS)

Grady, Julie R.

The purpose of this exploratory qualitative study was to investigate the practice of scientific inquiry in two secondary biology classes and one agriculture class from different schools in different communities. The focus was on teachers' interests and intentions for the students' participation in inquiry, the voices contributing to the inquiry, and students' opportunities to confront their conceptions of the nature of science (NOS). The Partnership for Research and Education in Plants (PREP) served as the context by providing students with opportunities to design and conduct original experiments to help elucidate the function(s) of a disabled gene in Arabidopsis thaliana . Transcripts of teacher and student semi-structured interviews, field notes of classroom observations and classroom conversations, and documents (e.g., student work, teacher handouts, school websites, PREP materials) were analyzed for evidence of the practice of scientific inquiry. Teachers were interested in implementing inquiry because of potential student learning about scientific research and because PREP supports course content and is connected to a larger scientific project outside of the school. Teachers' intentions regarding the implementation of inquiry reflected the complexity of their courses and the students' previous experiences. All inquiries were student-directed. The biology students' participation more closely mirrored the practice of scientists, while the agriculture students were more involved with the procedural display of scientific inquiry. All experiences could have been enhanced from additional knowledge-centered activities regarding scientific reasoning. No activities brought explicit attention to NOS. Biology activities tended to implicitly support NOS while the agriculture class activities tended to implicitly contradict NOS. Scientists' interactions contributed to implied support of the NOS. There were missed opportunities for explicit attention to NOS in all classes. The major voices contributing to the inquiry in all classrooms included those of teachers, students, technology, scientists, textbooks, and mandated standards; however, they were more prevalent in the biology classrooms than the agriculture classroom. The powers influencing the voice frequency may be related to the teachers' own teaching and research experiences, as well as the alignment of the expectations and values of students' participation in scientific inquiry and those associated with the school-classroom communities and the students' identities.

A novel habitat-based approach to predict impacts of marine protected areas on fishers.

While marine protected areas (MPAs) can simultaneously contribute to biodiversity conservation and fisheries management, the global network is biased towards particular ecosystem types, as it was largely established in an ad hoc fashion. The optimization of trade-offs between biodiversity benefits and socio-economic values increases implementation success and minimizes enforcement costs in the long run, but is often neglected in marine spatial planning (MSP). Although the acquisition of spatially explicit socioeconomic data is often perceived as a costly/secondary step in MSP, it is critical to account for lost opportunities by people whose activities will be restricted, especially fishers. Here we present an easily-reproducible habitat-based approach to estimate the spatial distribution of opportunity cost to fishers in data poor regions, assuming that the most accessible areas have higher values and their designation as no-take zones represents increased loss of fishing opportunities. Our method requires only habitat and bathymetric maps, a list of target species, the location of ports, and the relative importance for each port and/or vessel/gear type. The potential distribution of fishing resources is estimated from bathymetric ranges and benthic habitat distribution, while the relative importance of the different resources is estimated for each port, considering total catches (kg), revenues and/or stakeholder perception. Finally, the model can combine different cost layers to produce a comprehensive cost layer, and also allows for the evaluation of tradeoffs. The development of FishCake was based on data from a contentious conservation-planning arena (Abrolhos Bank, Brazil) in which attempts to expand MPA coverage failed due to fishers' resistance. The opportunity cost approach that we introduce herein allows for the incorporation of economic interests of different stakeholders and evaluation of tradeoffs among different stakeholder groups. The novel approach can be directly used to support conservation planning, in Abrolhos and elsewhere, and is expected to facilitate community consultation. This article is protected by copyright.

The management challenge for household waste in emerging economies like Brazil: realistic source separation and activation of reverse logistics.

PubMed

Fehr, M

2014-09-01

Business opportunities in the household waste sector in emerging economies still evolve around the activities of bulk collection and tipping with an open material balance. This research, conducted in Brazil, pursued the objective of shifting opportunities from tipping to reverse logistics in order to close the balance. To do this, it illustrated how specific knowledge of sorted waste composition and reverse logistics operations can be used to determine realistic temporal and quantitative landfill diversion targets in an emerging economy context. Experimentation constructed and confirmed the recycling trilogy that consists of source separation, collection infrastructure and reverse logistics. The study on source separation demonstrated the vital difference between raw and sorted waste compositions. Raw waste contained 70% biodegradable and 30% inert matter. Source separation produced 47% biodegradable, 20% inert and 33% mixed material. The study on collection infrastructure developed the necessary receiving facilities. The study on reverse logistics identified private operators capable of collecting and processing all separated inert items. Recycling activities for biodegradable material were scarce and erratic. Only farmers would take the material as animal feed. No composting initiatives existed. The management challenge was identified as stimulating these activities in order to complete the trilogy and divert the 47% source-separated biodegradable discards from the landfills. © The Author(s) 2014.

Mass sensing based on deterministic and stochastic responses of elastically coupled nanocantilevers.

Coupled nanomechanical systems and their entangled eigenstates offer unique opportunities for the detection of ultrasmall masses. In this paper we show theoretically and experimentally that the stochastic and deterministic responses of a pair of coupled nanocantilevers provide different and complementary information about the added mass of an analyte and its location. This method allows the sensitive detection of minute quantities of mass even in the presence of large initial differences in the active masses of the two cantilevers. Finally, we show the fundamental limits in mass detection of this sensing paradigm.

The authors use examples of youth civic engagement from Chile, South Africa, Central/Eastern Europe, and the United States--and also emphasize diversities among youth from different subgroups within countries--to illustrate common elements of the civic domain of youth development. These include the primacy of collective activity for forming political identities and ideas and the greater heterogeneity of civic compared to other discretionary activities, the groupways or accumulated opportunities for acting due to the groups (social class, gender, ethnic, caste, etc.) to which a young person belongs, and the role of mediating institutions (schools, community-based organizations, etc.) as spaces where youths' actions contribute to political stability and change.

Simulation in the clinical setting: towards a standard lexicon.

PubMed

Posner, Glenn D; Clark, Marcia L; Grant, Vincent J

2017-01-01

Simulation-based educational activities are happening in the clinical environment but are not all uniform in terms of their objectives, delivery, or outputs. While these activities all provide an opportunity for individual and team training, nuances in the location, timing, notification, and participants impact the potential outcomes of these sessions and objectives achieved. In light of this, there are actually many different types of simulation-based activity that occur in the clinical environment, which has previously all been grouped together as "in situ" simulation. However, what truly defines in situ simulation is how the clinical environment responds in its' natural state, including the personnel, equipment, and systems responsible for care in that environment. Beyond individual and team skill sets, there are threats to patient safety or quality patient care that result from challenges with equipment, processes, or system breakdowns. These have been labeled "latent safety threats." We submit that the opportunity for discovery of latent safety threats is what defines in situ simulation and truly differentiates it from what would be more rightfully called "on-site" simulation. The distinction between the two is highlighted in this article, as well as some of the various sub-types of in situ simulation.

Assessment of Foraging Devices as a Model for Decision-Making in Nonhuman Primate Environmental Enrichment

2014-01-01

Continued progress to move evidence-based best practices into community and regulatory animal welfare standards depends in part on developing common metrics to assess cost, benefit, and relative value. Here we describe a model approach to evidence-based evaluation and an example of comprehensive cost–benefit assessment for a common element of environmental enrichment plans for laboratory-housed nonhuman primates. Foraging devices encourage a species-typical activity that dominates the time budget of primates outside captivity and provide inherent cognitive challenges, physical activity demands, and multi-sensory stimulation. However, their implementation is not standard, and is challenged by perception of high costs and labor; nutritional and health concerns; and identification of best practices in implementation (that is, device types, food type, frequency of delivery and rotation). To address these issues, we directly compared monkeys’ engagement with different foraging devices and the comprehensive cost of implementing foraging opportunities. We recorded 14 adult male cynomolgus monkeys’ interactions with 7 types of devices filled with a range of enrichment foods. All devices elicited foraging behavior, but there were significant differences among them both initially and over subsequent observations. Devices that afforded opportunity for extraction of small food items and that posed manipulative challenge elicited greater manipulation. The cost of providing a foraging opportunity to a single monkey is roughly US$1, with approximately 80% attributable to labor. This study is the first to perform a rigorous cost–benefit analysis and comparison of common foraging devices included in environmental enrichment. Its broader significance lies in its contribution to the development of methods to facilitate improvement in evidence-based practices and common standards to enhance laboratory animal welfare.

From 2004 to 2011, a collaborative project was undertaken to enhance the capacity of the Government of Pakistan to implement an effective second-generation surveillance system for HIV/AIDS, known as the HIV/AIDS Surveillance Project (HASP). In four separate rounds, behavioural questionnaires were administered among injection drug users, and female, male and hijra (transgender) sex workers. Dried blood spots were collected for HIV testing. Through interviews with project staff in Pakistan and Canada, we have undertaken a critical review of the role of HASP in generating, using and translating knowledge, with an emphasis on capacity building within both the donor and recipient countries. We also documented ongoing and future opportunities for the translation of knowledge produced through HASP. Knowledge translation activities have included educational workshops and consultations held in places as diverse as Colombia and Cairo, and the implementation of HASP methodologies in Asia, the Middle East and sub-Saharan Africa. HASP methodologies have been incorporated in multiple WHO reports. Importantly, the donor country, Canada, has benefited in significant ways from this partnership. Operational and logistical lessons from HASP have, in turn, improved how surveillance is performed in Canada. Through this project, significant capacity was built among the staff of HASP, non-governmental organisations which were engaged as implementation partners, data coordination units which were established in each province, and in the laboratory. As is to be expected, different organisations have different agendas and priorities, requiring negotiation, at times, to ensure the success of collaborative activities. Overall, there has been considerable interest in and opportunities made for learning about the methodologies and approaches employed by HASP. Generally, the recognition of the strengths of the approaches and methodologies used by HASP has ensured an appetite for opportunities of mutual learning.

Initial Results from the STEM Student Experiences Aboard Ships (STEMSEAS) Program

NASA Astrophysics Data System (ADS)

Lewis, J. C.; Cooper, S. K.; Thomson, K.; Rabin, B.; Alberts, J.

2016-12-01

The Science Technology Engineering and Math Student Experiences Aboard Ships (STEMSEAS) program was created as a response to NSF's call (through GEOPATHS) for improving undergraduate STEM education and enhancing diversity in the geosciences. It takes advantage of unused berths on UNOLS ships during transits between expeditions. During its 2016 pilot year - which consisted of three transits on three different research vessels in different parts of the country, each with a slightly different focus - the program has gained significant insights into how best to create and structure these opportunities and create impact on individual students. A call for applications resulted in nearly 900 applicants for 30 available spots. Of these applicants, 32% are from minority groups underrepresented in the geosciences (Black, Hispanic, or American Indian) and 20% attend community colleges. The program was able to sail socioeconomically diverse cohorts and include women, veterans, and students with disabilities and from two- and four-year colleges. Twenty-three are underrepresented minorities, 6 attend community colleges, 5 attend an HBCU or tribal college, and many are at HSIs or other MSIs. While longer term impact assessment will have to wait, initial results and 6-month tracking for the first cohort indicate that these kinds of relatively short but intense experiences can indeed achieve significant impacts on students' perception of the geosciences, in their understanding of STEM career opportunities, their desire to work in a geoscience lab setting, and to incorporate geosciences into non-STEM careers. Insights were also gained into the successful makeup of mentor/leader groups, factors to consider in student selection, necessary pre- and post-cruise logistics management, follow-up activities, structure of activities during daily life at sea, increasing student networks and access to mentorships, and leveraging of pre-existing resources and ship-based opportunities. Additionally, lessons learned by working with multiple UNOLS ship operators can be applied to the growth of the program over time.

The Elderly Perceived Meanings and Values of Virtual Reality Leisure Activities: A Means-End Chain Approach.

PubMed

Lin, Cheng-Shih; Jeng, Mei-Yuan; Yeh, Tsu-Ming

2018-04-03

This study uses means-end chain (MEC) techniques to examine the awareness, decision-making procedure, and personal values of the elderly with regard to virtual reality leisure activities. The results of the study show that elderly respondents value virtual reality leisure activities that are fun, safe, and easy. In terms of outcome benefits, elderly respondents value feeling physically and mentally healthy, firsthand experience, and satisfied curiosity. In value terms, elderly respondents hope that their chosen virtual reality leisure activities improve not only their relationships with others, but also their enjoyment, quality of life, and sense of belonging. The results show that, while consumers with different awarenesses of virtual reality leisure activities have different decision-making processes, they share creating "good memories" as the terminal value with the most significant effect. This presents a potential opportunity to promote virtual reality leisure activities. Relevant bodies or enterprises can seek to create good memories in consumers by developing activities that are safe and fun, promote good health, and provide good service, thereby attracting the interest of elderly consumers.

It's All in the Lens: Differences in Views on Obesity Prevention between Advocates and Policy Makers

PubMed Central

Jones, Ellen; Nguyen, Leah; Kong, Jooyoung; Brownson, Ross C.; Bailey, Jessica H.

2012-01-01

Abstract Background: Intervention strategies to reduce obesity include policy and environmental changes that are designed to provide opportunities, support, and cues to help people develop healthier behaviors. Policy changes at the state level are one way to influence access, social norms, and opportunities for better nutrition and increased physical activity among the population. Methods: Ten states were selected for a broad variance in obesity rates and number of enacted obesity prevention policies during the years of 2006–2009. Within the selected states, a purely qualitative study of attitudes of childhood obesity policy using semistructured telephone interviews was conducted. Interviews were conducted with state policy makers who serve on public health committees. A set of six states that had more than eight childhood obesity policies enacted were selected for subsequent qualitative interviews with a convenience sample of well-established advocates. Results: Policy makers in states where there was more childhood obesity policy action believed in the evidence behind obesity policy proposals. Policy makers also varied in the perception of obesity as a constituent priority. The major differences between advocates and policy makers included a disconnect in information dissemination, opposition, and effectiveness of these policies. Conclusions: The findings from this study show differences in perceptions among policy makers in states with a greater number of obesity prevention bills enacted. There are differences among policy makers and advocates regarding the role and effectiveness of state policy on obesity prevention. This presents an opportunity for researchers and practitioners to improve communication and translation of evidence to policy makers, particularly in states with low legislation. PMID:22799551

Gross motor development and physical activity in kindergarten age children.

PubMed

Colella, Dario; Morano, Milena

2011-10-01

Physical activity in kindergarten is a fundamental part of the child's educational process. Body experience and physical activity contribute to the development of self-awareness and the learning of different modes of expression, as well as encouraging the acquisition of physically active lifestyles. Recent scientific evidence has confirmed the role of physical activity in disease prevention and quality of life improvement, and stressed the importance of integrated educational programmes promoting physical activity and healthy eating habits. A key priority of scientific research is to identify the opportunities and methods of motor learning and to increase the daily physical activity levels of children by reducing sedentary time and promoting active play and transport (i.e. walking, cycling). Family, school and community involvement are all needed to assure adherence to the official guidelines on how much physical activity children need to boost their health and stave off obesity.

Active Lifting During Martian Dust Storm

NASA Image and Video Library

2017-03-09

This false-color scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity documents movement of dust as a regional dust storm approached the rover's location on Feb. 24, 2017, during the 4,653rd Martian day, or sol, of the rover's work on Mars. Key to detecting the movement is that Pancam color images are combinations of different images taken a short time apart through different color filters. Note that along the horizon, the left portion of the image has a bluish band (with label and arrow in Figure 1). The component image admitting blue light was taken about 150 seconds after the component image admitting red light. A layer of dust-carrying wind hadn't reached this location by the earlier exposure, but had by the later one. This Sol 4653 Opportunity view is toward the north from the rover's location on the western rim of Endeavour Crater in the Meridiani Planum region of Mars. http://photojournal.jpl.nasa.gov/catalog/PIA21485

Crowdsourcing in biomedicine: challenges and opportunities.

2016-01-01

The use of crowdsourcing to solve important but complex problems in biomedical and clinical sciences is growing and encompasses a wide variety of approaches. The crowd is diverse and includes online marketplace workers, health information seekers, science enthusiasts and domain experts. In this article, we review and highlight recent studies that use crowdsourcing to advance biomedicine. We classify these studies into two broad categories: (i) mining big data generated from a crowd (e.g. search logs) and (ii) active crowdsourcing via specific technical platforms, e.g. labor markets, wikis, scientific games and community challenges. Through describing each study in detail, we demonstrate the applicability of different methods in a variety of domains in biomedical research, including genomics, biocuration and clinical research. Furthermore, we discuss and highlight the strengths and limitations of different crowdsourcing platforms. Finally, we identify important emerging trends, opportunities and remaining challenges for future crowdsourcing research in biomedicine. Published by Oxford University Press 2015.

Current and emerging challenges to public health in the 21st century are vastly different from those faced in previous centuries. And the shortage of health personnel and their low level of educational qualifications hindered the development of Chinese public health services. In order to fulfill this requirement, the Ministry of Education initiated a full-time, Master of Public Health (MPH) graduate programme in 2009. This study aimed to evaluate the level of graduate students' satisfaction with full-time Master of Public Health (MPH) education in China, and whether they would apply again for an MPH graduate degree if they had another opportunity to do so, as well as to identify the factors influencing their decision-making process. An anonymous, web-based survey questionnaire containing 61 items was distributed to 702 MPH students in 35 universities or colleges. The questions covered the categories of student admission, training goals, lecture courses, practical training, research activities and mentorship. Levels of satisfaction were compared between MPH students who would choose MPH again as their graduate degree if they had another opportunity to do so and those who would not. Key influencing factors of training satisfaction were identified using logistic regression models. A total of 65.10% of the participants would apply again for MPH education if they had another opportunity to do so. The factors influencing students' willingness included their university type, the time since admission and their initial willingness. In addition, the four common factors (admissions & lecture courses, research activities & mentorship, practical training and training goals) emerging from factor analysis were all significantly positively correlated with student willingness (p < 0.001). Most MPH students surveyed were highly satisfied with their MPH education and, although they advocated for improvements and reforms in some aspects, they would still choose MPH as their graduate degree again if they had another opportunity to do so.

NGC6872, hereafter the Condor, is a large spiral galaxy that is interacting with its closest companion, the S0 galaxy IC 4970. The extent of the Condor provides an opportunity for detailed investigation of the impact of the interaction on the current star formation rate and its history across the galaxy, on the age and spatial distribution of its stellar population, and on the mechanism that drives the star formation activity. To address these issues we analyzed the far-ultraviolet (FUV) to near-infrared (near-IR) spectral energy distribution of seventeen 10 kpc diameter regions across the galaxy, and derived their star formation history, current star formation rate, and stellar population and mass. We find that most of the star formation takes place in the extended arms, with very little star formation in the central 5 kpc of the galaxy, in contrast to what was predicted from previous numerical simulations. There is a trend of increasing star formation activity with distance from the nucleus of the galaxy, and no evidence for a recent increase in the current star formation rate due to the interaction. The nucleus itself shows no significant current star formation activity. The extent of the Condor also provides an opportunity to test the applicability of a single standard prescription for conversion of the FUV + IR (22 micrometer) intensities to a star formation rate for all regions. We find that the conversion factor differs from region to region, arising from regional differences in the stellar populations.

Simple Summary This paper provides insight into the role of farm animals in farm-based programs and their importance to different types of participants. Farm animals provide real work, close relationships, challenging tasks and opportunities for reflection. They also contribute to a welcoming atmosphere for various types of participants. Abstract We explore the role of farm animals in providing care to different types of participants at care farms (e.g., youngsters with behavioural problems, people with severe mental problems and people with dementia). Care farms provide alternative and promising settings where people can interact with animals compared to a therapeutic healthcare setting. We performed a literature review, conducted focus group meetings and carried out secondary data-analysis of qualitative studies involving care farmers and different types of participants. We found that farm animals are important to many participants and have a large number of potential benefits. They can (i) provide meaningful day occupation; (ii) generate valued relationships; (iii) help people master tasks; (iv) provide opportunities for reciprocity; (v) can distract people from them problems; (vi) provide relaxation; (vii) facilitate customized care; (viii) facilitate relationships with other people; (ix) stimulate healthy behavior; (x) contribute to a welcoming environment; (xi) make it possible to experience basic elements of life; and (xii) provide opportunities for reflection and feedback. This shows the multi-facetted importance of interacting with animals on care farms. In this study the types of activities with animals and their value to different types of participants varied. Farm animals are an important element of the care farm environment that can address the care needs of different types of participants. PMID:28574435

Sex and racial differences in preference for a caring morality in a corporate environment that promotes diversity and equal opportunity.

PubMed

Jones, Nona J

2002-10-01

This study investigated the caring moral perspective of managers in a corporation recognized as being a champion of promoting diversity and equal opportunity. Caring is described as a morality of responsibility and relationship, a sensitivity to the needs of persons. The study was based on the prediction that the attachment and caring shown elsewhere to be characteristic of the morality of females would be characteristic of all managers, regardless of sex or race in this kind of corporate environment. 121 male and female, African-American and Euro-American managers responded to a survey using three subscales of a Caring Morality Inventory: caring orientation, use of intuition and feeling to make a judgment, and concern with others in decision-making. Analysis showed female managers, regardless of race, scored significantly higher on the Caring Morality scale than the male managers, supporting other findings of sex differences in caring moral perspective and suggesting that working for a company actively promoting diversity and equal opportunity does not cancel out these differences. In addition, for this study it was assumed that, although African Americans, in general, may have been sensitized to lean more toward a caring morality, any racial differences in caring morality would be cancelled out by the fact that all of the managers work for the same prodiversity and, by assumption, more sensitive company. The Euro-American managers, regardless of sex, actually scored higher on the Caring Morality scale than did the African-American managers, with the difference being attributable solely to the greater tendency of the Euro-American managers to use intuition and feeling to make a judgment.

The Flipped Classroom: An active teaching and learning strategy for making the sessions more interactive and challenging.

Sultan, Amber Shamim

2018-04-01

Flipping the classroom is a pedagogical model that employs easy to use, readily accessible technology based resources such as video lectures, reading handouts, and practice problems outside the classroom, whereas interactive group-based, problem-solving activities conducted in the classroom. This strategy permits for an extended range of learning activities during the session. Using class time for active learning provides greater opportunity for mentoring and peer to peer collaboration. Instead of spending too much time on delivering lectures, class time can best be utilized by interacting with students, discussing their concerns related to the particular topic to be taught, providing real life examples relevant to the course content, challenging students to think in a broader aspect about complex process and encouraging different team based learning activities.

Animal health surveillance enables the detection and control of animal diseases including zoonoses. Under the EU-FP7 project RISKSUR, a survey was conducted in 11 EU Member States and Switzerland to describe active surveillance components in 2011 managed by the public or private sector and identify gaps and opportunities. Information was collected about hazard, target population, geographical focus, legal obligation, management, surveillance design, risk-based sampling, and multi-hazard surveillance. Two countries were excluded due to incompleteness of data. Most of the 664 components targeted cattle (26·7%), pigs (17·5%) or poultry (16·0%). The most common surveillance objectives were demonstrating freedom from disease (43·8%) and case detection (26·8%). Over half of components applied risk-based sampling (57·1%), but mainly focused on a single population stratum (targeted risk-based) rather than differentiating between risk levels of different strata (stratified risk-based). About a third of components were multi-hazard (37·3%). Both risk-based sampling and multi-hazard surveillance were used more frequently in privately funded components. The study identified several gaps (e.g. lack of systematic documentation, inconsistent application of terminology) and opportunities (e.g. stratified risk-based sampling). The greater flexibility provided by the new EU Animal Health Law means that systematic evaluation of surveillance alternatives will be required to optimize cost-effectiveness.

Understanding the potential and challenges of adenoma treatment as a prevention opportunity: insights from the BeWEL formative study.

To explore prevention opportunities presented by colorectal adenoma diagnosis and inform engagement strategies for the BeWEL study (body weight and physical activity lifestyle intervention for colorectal cancer screening participants who have undergone adenoma removal). Qualitative study comprising 4 purposively sampled focus groups conducted in urban and rural areas in Tayside, Scotland, with different deprivation levels. Participants were men and women (n=17) aged 50-74 with BMI>25 kg/m(2) with removal of adenoma detected by colorectal cancer screening. Adenoma diagnosis presents both opportunities and challenges for prevention. Some patients perceived adenoma as minor and not sufficiently motivating to act as a 'teachable moment'. Patients had low awareness of the relationship between adenoma and lifestyle factors, and received little information on prevention during screening and treatment. Consequently they interpreted post-treatment 'all clear' messages as validation of existing lifestyles, and did not see the relevance of prevention advice. Receptiveness increased when the association between lifestyle, adenoma recurrence and other illness was explained. The study illustrates the value of exploratory research into patient understanding to improve communications and health services. Without unduly worrying patients, professionals should explain how to reduce risk of adenoma, cancer and other diseases, particularly through diet, physical activity and weight reduction.

1987-01-01

The encounters of five spacecraft with Halley's Comet during 6-14 March 1986 offered a unique opportunity to calibrate the solar-wind interaction with cometary plasmas as recorded by remote wide-field and narrow-field/narrowband imaging. Perhaps not generally recognized in the comet community is the additional opportunity offered by the Halley Armada to study the structure of the solar-wind and interplanetary magnetic field (IMF) in three dimensions using five sets of data obtained over similar time intervals and heliocentric distances, but at somewhat different heliolatitudes. In fact, the two problems, i.e., comet physics and the structure of the interplanetary medium, are coupled if one wants to understand what conditions pertained at the comet between the encounters. This relationship is discussed.

Michimi, Akihiko; Wimberly, Michael C

2012-01-01

To assess the associations of the natural environment with obesity and physical activity in nonmetropolitan areas of the United States among representative samples by using 2 indices of outdoor activity potential (OAP) at the county level. We used the data from 457,820 and 473,296 noninstitutionalized adults aged over 18 years for obesity and physical activity, respectively, from the 2000-2006 Behavioral Risk Factor Surveillance System. The OAP indices were (1) a recreational opportunity index based on 24 variables related to outdoor physical activity, such as the number of facilities available for walking, biking, hiking, and swimming derived from the 1997 National Outdoor Recreation Supply Information System; and (2) a natural amenities index which was based on physical and social environmental characteristics, such as climate, topographic relief, land cover, and tourism. We fitted logistic regression models using generalized estimating equations to control for county level intracorrelation and tested each index separately to assess its relationship with obesity and physical activity. Recreational opportunities were higher in areas with greater natural amenities. After controlling for individual-level socioeconomic and demographic characteristics, the prevalence of obesity decreased and propensity for physical activity increased with increasing levels of both recreational opportunities and natural amenities. Multiple indices of OAP based on characteristics of the built, natural and social environments were associated with decreased obesity and increased physical activity in nonmetropolitan areas. Public health interventions should consider the opportunities and limitations offered by the natural environment for promoting physical activity and reducing obesity in rural areas. © 2012 National Rural Health Association.

2004-05-01

A simple blind spot activity has been devised to help students discard misconceptions about image formation by lenses. Our hands-on experiment, in which students determine the location and size of their blind spots, is suitable for various age groups at different educational levels. The activity provides an opportunity to teach students how to measure objects indirectly using triangles and encourages them to think about the number of measurements needed to gain confidence in a value. It also gives teachers another interesting experiment in which to discuss the nature of uncertainties and how to deal with them. Student responses to the activity, performed with pre-engineering students and non-science majors, are discussed.

Whereas biosensors have been usually proposed as analytical tools, used to investigate the surrounding media pursuing an analytical answer, we have used a biosensor-like device to characterize the microbial cells immobilized on it. We have studied the kinetics of transport and degradation of glucose at different concentrations and temperatures. When glucose concentrations of 15 and 1.5 mM were assayed, calculated activation energies were 25.2 and 18.4 kcal mol(-1), respectively, in good agreement with previously published data. The opportunity and convenience of using Arrhenius plots to estimate the activation energy in metabolic-related processes is also discussed.

Experience of cooperative learning in engineering

The objective of this work is to share the authors' experience towards a different mode of teaching/learning method. Cooperative learning (Jigsaw) was employed on the University of Vigo's fourth-year engineering students. The results of the experience show that cooperative learning is quite a viable alternative to the classical way of lecturing at the university when the number of students is not too high. The authors' observation indicates that students did not show a lot of interest towards the new learning style but their resistance changed once they began the activity. The Jigsaw method has proved to be a useful tool for improving the learning process so that students have the opportunity to participate actively in the learning activities.

The Antibacterial Activity of Metal Complexes Containing 1,10- phenanthroline: Potential as Alternative Therapeutics in the Era of Antibiotic Resistance.

2017-01-01

The "antibiotic era", characterized by the overuse and misuse of antibiotics, over the last half-century has culminated in the present critical "era of resistance". The treatment of bacterial infections is challenging because of a decline in the current arsenal of useful antibiotics and the slow rate of new drug development. The discovery of a new gene (mcr-1) in 2015, which enables bacteria to be highly resistant to polymyxins (such as colistin), the last line of antibiotic defence left, heralds a new level of concern as this gene is susceptible to horizontal gene transfer, with alarming potential to be spread between different bacterial populations, suggesting that the progression from "extensive drug resistance" to "pan-drug resistance" may be inevitable. Clearly there is a need for the development of novel classes of anti-bacterial agents capable of killing bacteria through mechanisms that are different to those of the known classes of antibiotics. 1,10-phenanthroline (phen) is a heterocyclic organic compound which exerts in vitro antimicrobial activity against a broad-spectrum of bacteria. The antimicrobial activity of phen can be significantly modulated by modifying its structure. The development of metal-phen complexes offers the medicinal chemist an opportunity to expand such structural diversity by controlling the geometry and varying the oxidation states of the metal centre, with the inclusion of appropriate auxiliary ligands in the structure, offering the opportunity to target different biochemical pathways in bacteria. In this review, we summarize what is currently known about the antibacterial capability of metal-phen complexes and their mechanisms of action.

Characteristics of Exemplary Science, Technology, Engineering, and Math (STEM)-Related Experiential Learning Opportunities

NASA Astrophysics Data System (ADS)

Simmons, Jamie Munn

Experiential opportunities at the secondary level give students the "intimate and necessary relation between the processes of actual experience and education" (Dewey, 1938, p. 19- 20). Career and Technical Education classes (CTE) and co-curricular experiences, one type of experiential learning, underpin and cultivate student curiosity and often channel interests into STEM-related post-secondary disciplines and career choices. There is little existent research on the characteristics of exemplary experiential learning opportunities and the impact on stakeholders. This study is intended to identify the qualities and characteristics of an exemplary secondary experience through the lived experiences of the stakeholders; students, STEM-related teachers, and CTE/STEM Administrators. A qualitative research design was used to examine characteristics and implications for students of four STEM-related programs throughout Virginia. Conclusions from the study include fundamental principles for providing exemplary experiential STEM-related learning opportunities. These principles include: providing hands-on, real world learning opportunities for students, providing learning opportunities that will enhance student ownership in their learning, providing unique and comprehensive career exploration opportunities for students, providing a schedule for teachers that will give them time to plan, deliver, and manage exemplary experiential learning opportunities, providing continual teacher and administrator in-service training relative to planning and implementing exemplary experiential learning opportunities, investing appropriate funds for providing exemplary experiential learning opportunities. Establishing and maintaining active partnerships with business/industry and colleges/universities, and maintaining active advisory communities, providing appropriate staff to support the provision of exemplary experiential learning opportunities is needed. The need for adequate funding, improving perception of CTE and STEM programs, and small class sizes was also recommended.

Medical students' opportunities to participate and learn from activities at an internal medicine ward: an ethnographic study

2017-01-01

Objectives To optimise medical students’ early clerkship is a complex task since it is conducted in a context primarily organised to take care of patients. Previous studies have explored medical students’ perceptions of facilitation and hindrance of learning. However, the opportunities for medical student to learn within the culture of acute medicine care have not been fully investigated. This study aimed to explore how medical students approach, interact and socialise in an acute internal medicine ward context, and how spaces for learning are created and used in such a culture. Design and setting Ethnographic observations were performed of medical students' interactions and learning during early clerkship at an acute internal medicine care ward. Field notes were taken, transcribed and analysed qualitatively. Data analysis was guided by Wenger's theory of communities of practice. Participants 21 medical students and 30 supervisors participated. Results Two themes were identified: Nervousness and curiosity—students acted nervously and stressed, especially when they could not answer questions. Over time curiosity could evolve. Unexplored opportunities to support students in developing competence to judge and approach more complex patient-related problems were identified. Invited and involved—students were exposed to a huge variation of opportunities to learn, and to interact and to be involved. Short placements seemed to disrupt the learning process. If and how students became involved also depended on supervisors' activities and students' initiatives. Conclusions This study shed light on how an acute internal medicine ward culture can facilitate medical students' possibilities to participate and learn. Medical students' learning situations were characterised by questions and answers rather than challenging dialogues related to the complexity of presented patient cases. Further, students experienced continuous transfers between learning situations where the potential to be involved differed in a wide variety of ways. PMID:28196948

Aging of population is an inevitable process by which the number of elderly people is increasing. Rapid development of information and communication technology (ICT) is changing basic needs of elderly people; therefore society should ensure opportunities for elderly to learn and use ICT in a way to manage their daily life activities and in this way enable them participation in the information and knowledge society. The purpose of the study was to find out whether elderly are acquainted with the advanced technology and to what extent they use it or they desire to use it. Within the single point study we interviewed 100 randomly selected elderly people from different geographical regions in Slovenia. Results showed the differences in the use of advanced technology by Slovenian regions; therefore in the future activities should be focused on organizing promotional and demonstrational activities including ICT courses to increase elderly's motivation for ICT interaction.

Synthetic biology for the directed evolution of protein biocatalysts: navigating sequence space intelligently

PubMed Central

Currin, Andrew; Swainston, Neil; Day, Philip J.

2015-01-01

The amino acid sequence of a protein affects both its structure and its function. Thus, the ability to modify the sequence, and hence the structure and activity, of individual proteins in a systematic way, opens up many opportunities, both scientifically and (as we focus on here) for exploitation in biocatalysis. Modern methods of synthetic biology, whereby increasingly large sequences of DNA can be synthesised de novo, allow an unprecedented ability to engineer proteins with novel functions. However, the number of possible proteins is far too large to test individually, so we need means for navigating the ‘search space’ of possible protein sequences efficiently and reliably in order to find desirable activities and other properties. Enzymologists distinguish binding (K d) and catalytic (k cat) steps. In a similar way, judicious strategies have blended design (for binding, specificity and active site modelling) with the more empirical methods of classical directed evolution (DE) for improving k cat (where natural evolution rarely seeks the highest values), especially with regard to residues distant from the active site and where the functional linkages underpinning enzyme dynamics are both unknown and hard to predict. Epistasis (where the ‘best’ amino acid at one site depends on that or those at others) is a notable feature of directed evolution. The aim of this review is to highlight some of the approaches that are being developed to allow us to use directed evolution to improve enzyme properties, often dramatically. We note that directed evolution differs in a number of ways from natural evolution, including in particular the available mechanisms and the likely selection pressures. Thus, we stress the opportunities afforded by techniques that enable one to map sequence to (structure and) activity in silico, as an effective means of modelling and exploring protein landscapes. Because known landscapes may be assessed and reasoned about as a whole, simultaneously, this offers opportunities for protein improvement not readily available to natural evolution on rapid timescales. Intelligent landscape navigation, informed by sequence-activity relationships and coupled to the emerging methods of synthetic biology, offers scope for the development of novel biocatalysts that are both highly active and robust.

Research Experiences in Community College Science Programs

NASA Astrophysics Data System (ADS)

Beauregard, A.

2011-12-01

The benefits of student access to scientific research opportunities and the use of data in curriculum and student inquiry-driven approaches to teaching as effective tools in science instruction are compelling (i.e., Ledley, et al., 2008; Gawel & Greengrove, 2005; Macdonald, et al., 2005; Harnik & Ross. 2003). Unfortunately, these experiences are traditionally limited at community colleges due to heavy faculty teaching loads, a focus on teaching over research, and scarce departmental funds. Without such hands-on learning activities, instructors may find it difficult to stimulate excitement about science in their students, who are typically non-major and nontraditional. I present two different approaches for effectively incorporating research into the community college setting that each rely on partnerships with other institutions. The first of these is a more traditional approach for providing research experiences to undergraduate students, though such experiences are limited at community colleges, and involves student interns working on a research project under the supervision of a faculty member. Specifically, students participate in a water quality assessment study of two local bayous. Students work on different aspects of the project, including water sample collection, bio-assay incubation experiments, water quality sample analysis, and collection and identification of phytoplankton. Over the past four years, nine community college students, as well as two undergraduate students and four graduate students from the local four-year university have participated in this research project. Aligning student and faculty research provides community college students with the unique opportunity to participate in the process of active science and contribute to "real" scientific research. Because students are working in a local watershed, these field experiences provide a valuable "place-based" educational opportunity. The second approach links cutting-edge oceanographic research with my community college students by partnering with a research oceanographer. Through this partnership, students have had access to an active oceanographic researcher through classroom visits, use of data in curriculum, and research/cruise progress updates. With very little research activity currently going on at the community college, this "window" into scientific research is invaluable. Another important aspect of this project is the development of a summer internship program that has allowed four community college students to work directly with an oceanographer in her lab for ten weeks. This connection of community college students with world-class scientists in the field promotes better understanding of research and potentially may encourage more students to major in the sciences. In either approach, the interaction with scientists at different stages of their careers, from undergraduate and graduate students at universities to post docs and research scientists, also provides community college students with the opportunity to gain insight into possible career pathways. For both majors and non-majors, a key outcome of such experiences will be gaining experience in using inquiry and reasoning through the scientific method and becoming comfortable with data and technology.

Cheesman, Margaret F; Jennings, Mary Beth; Klinger, Lisa

2013-01-01

Measures of accessibility typically focus on the physical environment and aspects relating to getting into and out of spaces. The transient sound environment is less well characterized in typical accessibility measures. Hearing accessibility measures can be based upon physical indices or functional assessment. The physical measures are indices that use signal-to-noise ratios to evaluate audibility while the functional assessment tool adopts universal design for hearing (UDH) principles derived from principles of universal design. The UDH principles include (1) Optimization of the hearing environment for all; (2) Optimization of interactions between persons and objects to promote better hearing in an environment; (3) Optimization of opportunities for people to have multiple choices of interactions with one another; (4) Optimization of opportunities for people to perform different activities in and across environments; (5) Optimization of opportunities for people to have safe, private, and secure use of the environment while minimizing distraction, interference, or cognitive loading; and (6) Optimization of opportunities for people to use the environment without extra steps for hearing access during preparatory, use and/or after use phases. This paper compares the two approaches using case examples from post-secondary classrooms in order to describe the potential advantages and limitations of each.

Two studies were conducted to investigate cultural differences in opportunity cost consideration between Chinese and Euro-Canadians. Opportunity cost is defined as the cost of a benefit that must be forgone in order to pursue a better alternative (Becker et al., 1974). In both studies, participants read about hypothetical purchase scenarios, and then decided whether they would buy a certain product. Opportunity cost consideration was measured in two ways: (1) participants' thoughts pertaining to other (nonfocal) products while making decisions; (2) participants' decisions not to buy a focal product (Study 1) or a more expensive product (Study 2). Across both indexes, we found that after controlling for individual difference variables and amount of pocket money, Chinese participants in China considered financial opportunity cost more than Euro-Canadians in Study 1. Similar results were observed in Study 2 when comparing Chinese in Canada with Euro-Canadians However, the cultural effect on opportunity cost consideration was confounded by family income in Study 2. Implications for resource management, limitations of the current research and directions for future research are discussed.

Increased fMRI signal with age in familial Alzheimer’s disease mutation carriers

Although many Alzheimer’s disease (AD) patients have a family history of the disease, it is rarely inherited in a predictable way. Functional magnetic resonance imaging (fMRI) studies of non-demented adults carrying familial AD mutations provide an opportunity to prospectively identify brain differences associated with early AD-related changes. We compared fMRI activity of 18 non-demented autosomal dominant AD mutation carriers with fMRI activity in 8 of their non-carrier relatives as they performed a novelty encoding task in which they viewed novel and repeated images. Because age of disease onset is relatively consistent within families, we also correlated fMRI activity with subjects’ distance from the median age of diagnosis for their family. Mutation carriers did not show significantly different voxelwise fMRI activity from non-carriers as a group. However, as they approached their family age of disease diagnosis, only mutation carriers showed increased fMRI activity in the fusiform and middle temporal gyri. This suggests that during novelty encoding, increased fMRI activity in the temporal lobe may relate to incipient AD processes. PMID:21129823

Biogas pre-upgrading by adsorption of trace compounds onto granular activated carbons and an activated carbon fiber-cloth.

PubMed

Boulinguiez, B; Le Cloirec, P

2009-01-01

The study assesses the adsorption onto activated carbon materials of selected volatile organic compounds -VOCs- (dichloromethane, 2-propanol, toluene, siloxane D4) in a biogas matrix composed of methane and carbon dioxide (55:45 v/v). Three different adsorbents are tested, two of them are granular activated carbon (GAC), and the last is an activated carbon fiber-cloth (ACFC). The adsorption isotherm data are fitted by different models by nonlinear regression. The Langmuir-Freundlich model appears to be the adequate one to describe the adsorption phenomena independently of the VOC considered or the adsorbent. The adsorbents present attractive adsorption capacity of the undesirable compounds in biogas atmosphere though the maximum adsorption capacities for a VOC are quite different from each other. The adsorption kinetics are characterized through three coefficients: the initial adsorption coefficient, the external film mass transfer coefficient and the internal diffusion coefficient of Weber. The ACFC demonstrates advanced kinetic yields compared to the granular activated carbon materials whatever VOC is considered. Therefore, pre-upgrading of biogas produced from wastewater sludge or co-digestion system by adsorption onto activated carbon appears worth investigating. Especially with ACFC material that presents correct adsorption capacities toward VOCs and concrete regeneration process opportunity to realize such process.

Global health training opportunities have figured prominently into medical students' residency program choices across a range of clinical specialties. To date, however, the national scope of global mental health education has not heretofore been systematically assessed. We therefore sought to characterize the distribution of global health training opportunities in US graduate psychiatric education. We examined the web pages of all US psychiatry residency training programs, along with search results from a systematic Google query designed to identify global health training opportunities. Of the 183 accredited US psychiatry residency programs, we identified 17 programs (9.3%) offering 28 global health training opportunities in 64 countries. Ten psychiatry residency programs offered their residents opportunities to participate in one or more elective-based rotations, eight offered research activities, and six offered extended field-based training. Most global health training opportunities occurred within the context of externally administered, institution-wide initiatives generally available to residents from a range of clinical specialties, rather than within internally administered departmental initiatives specifically tailored for psychiatry residents. There are relatively few global health training opportunities in US graduate psychiatric education. These activities have a clear role in enhancing mastery of Accreditation Council for Graduate Medical Education core competencies, but important challenges related to program funding and evaluation remain.

Purpose Even though physical education (PE) is an evidence-based strategy for providing and promoting physical activity, alternative programs such as Junior Reserve Officer Training Corps (JROTC) are commonly substituted for PE in many states. The purpose of this study was to compare student physical activity and lesson contexts during high school PE and JROTC sessions. Method SOFIT (System for Observing Fitness Instruction Time) was used to assess PE and JROTC sessions (N=38 each) in 4 high schools that provided both programs. Data were analyzed using t-tests, negative binomial regression, and logistic regression. Results Students engaged in significantly more moderate to vigorous physical activity during PE than JROTC sessions and they were significantly less sedentary. Significant differences between the two program types were also found among lesson contexts. Conclusions PE and JROTC provide substantially different content and contexts and students in them engage in substantially different amounts of moderate to vigorous physical activity. Students in JROTC, and perhaps other alternative programs, are less likely to accrue health-supporting physical activity and engage in fewer opportunities to be physically fit and motorically skilled. Policies and practices for providing substitutions for PE should be carefully examined. PMID:25141093

Edwards, Michael B; Kanters, Michael A; Bocarro, Jason N

2011-07-01

This study's purpose was to assess the opportunities for North Carolina adolescents to be physically active in extracurricular middle school environments and to compare opportunities across community types. Data were analyzed based on the results of an electronic questionnaire distributed to a sample of 431 schools with a response rate of 75.4% (N = 325). Nearly all schools offered interscholastic sports while fewer than half offered intramurals or noncompetitive activities to students. "Open gym" was offered at only 35% of schools, while 24% of schools offered extracurricular activities to students with disabilities. Overall, 43.4% of schools offered special transportation to students who participated in some extracurricular physical activities. Schools in rural areas generally offered fewer programs and had fewer supports than schools located in more urbanized areas. Over two-thirds of rural schools offered no extracurricular programs other than interscholastic sports. Schools can be important settings for physical activity. North Carolina's middle schools and its rural schools in particular, are falling short in efforts to provide extracurricular physical activity programming recommended by researchers and policy groups. Lower accessibility to extracurricular physical activities may partially contribute to higher levels of physical inactivity found in the state.

Exploiting the Bioactive Properties of the Dentin-Pulp Complex in Regenerative Endodontics.

Smith, Anthony J; Duncan, Henry F; Diogenes, Anibal; Simon, Stephane; Cooper, Paul R

2016-01-01

The development of regenerative endodontic therapies offers exciting opportunities for future improvements in treatment outcomes. Advances in our understanding of regenerative events at the molecular and cellular levels are helping to underpin development of these therapies, although the various strategies differ in the translational challenges they pose. The identification of a variety of bioactive molecules, including growth factors, cytokines, chemokines, and matrix molecules, sequestered within dentin and dental pulp provides the opportunity to present key signaling molecules promoting reparative and regenerative events after injury. The protection of the biological activity of these molecules by mineral in dentin before their release allows a continuing supply of these molecules, while avoiding the short half-life and the non-human origin of exogenous molecules. The ready release of these bioactive molecules by the various tissue preparation agents, medicaments, and materials commonly used in endodontics highlights the opportunities for translational regenerative strategies exploiting these molecules with little change to existing clinical practice.

Gandhi, Punit; Berggren, Calvin; Livezey, Jesse; Olf, Ryan

2014-11-01

We describe a set of conceptual activities and hands-on experiments based around understanding the dynamics of a slinky that is hung vertically and released from rest. The motion, or lack thereof, of the bottom of the slinky after the top is dropped sparks students' curiosity by challenging their expectations and provides context for learning about scientific model building. This curriculum helps students learn about the model building process by giving them an opportunity to enlist their collective intellectual and creative resources to develop and explore two different physical models of the falling slinky system. By engaging with two complementary models, students not only have the opportunity to understand an intriguing phenomenon from multiple perspectives, but also learn deeper lessons about the nature of scientific understanding, the role of physical models, and the experience of doing science. The activities we present were part of a curriculum developed for a week-long summer program for incoming freshmen as a part of the Compass Project at UC Berkeley, but could easily be implemented in a wide range of classrooms at the high school or introductory college level.

PROBLEM: Because researchers and policy-makers work in different spheres, policy decisions in the health arena are often not based on available scientific evidence. APPROACH: We describe a model that illustrates the policy process and how to work strategically to translate knowledge into policy actions. Several types of activity--agenda-setting, coalition building and policy learning--together can create a window of opportunity for policy change. LOCAL SETTING: Activities were undertaken as part of the Kenyan Ministry of Health's new decentralized planning-process. The objective was to ensure that the results of a national assessment of health services were used in the preparation of district-level health plans. RELEVANT CHANGES: Following the intervention, 70 district-level, evidence-based work plans were developed and approved by the Kenyan Ministry of Health. LESSONS LEARNED: Substantial investment and effort are needed to bring stakeholders together to work towards policy change. More in-depth evaluation of these efforts can aid understanding of how systematic approaches to policy change can be replicated elsewhere. PMID:16917657

To evaluate environmental obesogenic-related factors, such as physical activity in neighborhoods and schools, nutritional behavior, and intervention programs. Critical analysis of literature with personal point of view from infant obesity experts and political advisors for public intervention. Although obesity is a public health problem affecting several age groups, it is among children and adolescents that it plays a more important role, due to treatment complexity, high likelihood of persistence into adulthood, and association with other non-transmissible diseases while still in early age. Environment is a main component of the genesis and outcomes in the near future or long term. Modification of intake with high-density food, meal skipping, and high intake of saturated fat, sugar, and salt, associated to high levels of sedentarism are main causes of obesity. Intervention opportunities are related to modifications in political, environmental, and individual settings. School and physical activities in the educational environment are intertwined with nutrition intervention in continuous education. A critical review of some different scenarios in Latin American countries is presented. Copyright © 2016 Sociedade Brasileira de Pediatria. Published by Elsevier Editora Ltda. All rights reserved.

Implementing a comprehensive school physical activity program (CSPAP) effectively addresses public health issues by providing opportunities for physical activity (PA). Grounded in the Diffusion of Innovations model, the purpose of this study was to identify how health promotion efforts facilitate opportunities for PA. Physical and health education teachers (N = 256) nationwide were surveyed using a CSPAP Index to identify teacher's efforts for providing opportunities for PA within a school setting. A hierarchical regression analysis revealed total number of PA opportunities was significantly predicted by teachers' health promotion efforts, p < .001. Sex and years of experience were not significant covariates, p = .35, in the final step of the model. Accounting for teaching environments, the model was significant, p < .001. The strongest predictors were the promotional efforts of PA for family and community, p < .001, PA for staff members, p < .01, PA during the school day, p < .05, and PA before school, p < .05. To increase PA opportunities for children in schools, emphasis should be placed on health promotion. This study confirms the importance of teachers involving family, community, and staff members as co-health promoters when trying to increase PA engagement surrounding schools. © 2016, American School Health Association.

What are the views and perceptions of people with chronic obstructive pulmonary disease (COPD) regarding maintaining an active lifestyle following a course of pulmonary rehabilitation? Qualitative study of two focus groups using a grounded theory approach. Sixteen people with COPD who had completed a course of pulmonary rehabilitation. Data from focus groups concurred and five main themes emerged: value of pulmonary rehabilitation, ongoing exercise, professional support, peer social support, and health status. Pulmonary rehabilitation was seen as facilitating greater participation in everyday activity by improving physical ability and confidence to manage breathlessness, and reducing fear about exertional activity. An exercise routine following rehabilitation was perceived as essential for maintaining activity, with participants voicing a need for ongoing, structured and supervised sessions to maintain new found abilities. The exercise facility presented a possible barrier to attendance due to its potential to provoke feelings of embarrassment or intimidation. Professional and peer support were identified as key elements; participants expressed a desire to exercise within a peer group combined with an opportunity for social interaction. Health status relating to COPD symptoms was also identified as negatively impacting on physical activity participation. Confidence or self-efficacy for physical activity emerged as a prominent factor within main themes. The opportunity for structured, ongoing exercise with peer and professional support, in a suitable venue, is perceived as important to people with COPD in facilitating a physically active lifestyle following pulmonary rehabilitation. This desire for such opportunities may be related to individuals' self-efficacy towards physical activity. Copyright © 2012 Australian Physiotherapy Association. Published by .. All rights reserved.

Parks provide opportunities for physical activity for children. This study examined sex differences in correlates of park-based physical activity because differences may indicate that a standard environmental intervention to increase activity among children may not equally benefit boys and girls. The System for Observation Play and Recreation in Communities was used to measure physical activity among 2,712 children and adolescents in 20 neighborhood parks in Durham, North Carolina, in 2007. Sedentary activity, walking, vigorous park activity, and energy expenditure were the primary outcome variables. Hierarchical logit regression models of physical activity were estimated separately for boys and girls. Type of activity area and presence of other active children were positively associated with boys' and girls' physical activity, and presence of a parent was negatively associated. A significant interaction involving number of recreation facilities in combination with formal activities was positively associated with girls' activity. A significant interaction involving formal park activity and young boys (aged 0-5 y) was negatively associated with park-based physical activity. Activity area and social correlates of park-based physical activity were similar for boys and girls; findings for formal park programming, age, and number of facilities were mixed. Results show that girls' physical activity was more strongly affected by social effects (eg, presence of other active children) whereas boys' physical activity was more strongly influenced by the availability of park facilities. These results can inform park planning and design. Additional studies are necessary to clarify sex differences in correlates of park-based physical activity.

2003-01-01

Aeronautics research has seriously declined partly because of the perception that it is a mature science and only incremental improvements are possible. Recent aeronautics roadmapping activities at NASA Langley paint a different picture of the future. Breakthroughs are still felt to be possible if we expand the current design space of today's vehicles and optimize the airspace and vehicles as a system. The paper describes some of the challenges that the aircraft and airline industry face. These challenges include political, technical and environmental issues. Examples of the opportunities and technologies that could provide a different vision for the future are discussed.

Discussion of women, gender equality, and diabetes should be placed in the context of United Nations mandates on women's health which highlight the need for equal access to information, prevention activities, services, and care across the life cycle. Gender differences and inequalities have been identified in relation to causes and consequences of diabetes and access to services and support between women and men, and among different groups of women. Appropriate gender-sensitive policy responses, including research and data collection, need to be developed. The recent United Nations resolution on diabetes provides an opportunity to strengthen the focus on women and diabetes.

Science Planning and Orbit Classification for Solar Probe Plus

NASA Astrophysics Data System (ADS)

Kusterer, M. B.; Fox, N. J.; Rodgers, D. J.; Turner, F. S.

2016-12-01

There are a number of challenges for the Science Planning Team (SPT) of the Solar Probe Plus (SPP) Mission. Since SPP is using a decoupled payload operations approach, tight coordination between the mission operations and payload teams will be required. The payload teams must manage the volume of data that they write to the spacecraft solid-state recorders (SSR) for their individual instruments for downlink to the ground. Making this process more difficult, the geometry of the celestial bodies and the spacecraft during some of the SPP mission orbits cause limited uplink and downlink opportunities. The payload teams will also be required to coordinate power on opportunities, command uplink opportunities, and data transfers from instrument memory to the spacecraft SSR with the operation team. The SPT also intend to coordinate observations with other spacecraft and ground based systems. To solve these challenges, detailed orbit activity planning is required in advance for each orbit. An orbit planning process is being created to facilitate the coordination of spacecraft and payload activities for each orbit. An interactive Science Planning Tool is being designed to integrate the payload data volume and priority allocations, spacecraft ephemeris, attitude, downlink and uplink schedules, spacecraft and payload activities, and other spacecraft ephemeris. It will be used during science planning to select the instrument data priorities and data volumes that satisfy the orbit data volume constraints and power on, command uplink and data transfer time periods. To aid in the initial stages of science planning we have created an orbit classification scheme based on downlink availability and significant science events. Different types of challenges arise in the management of science data driven by orbital geometry and operational constraints, and this scheme attempts to identify the patterns that emerge.

How "struggling" readers engage in literacy events in middle school science An analysis of interactions in literacy events

Palmer, Kristin Cartwright

This study examined opportunities for participation and learning for "struggling" readers in a sixth grade science classroom. Literacy practices, language differences, activity structures, and the social and cultural identities and associated practices and everyday funds of knowledge of both "struggling" and nonstruggling readers in one sixth grade science classroom were documented and analyzed using a qualitative research design. Over sixteen hours of audio and video recordings as well as numerous student work samples were transcribed and analyzed. Analyses of the classroom interactions and artifacts documented in this study revealed several important affordances available in the context of this classroom related to opportunities for speaking and listening, some uses of print texts, and student agency in interactions. Student learning was found to be constrained by macrocontextual factors, text difficulty, and student history.

Evidence for Opportunity Cost Neglect in the Poor.

2018-01-01

People often neglect opportunity costs: They do not fully take into account forgone alternatives outside of a particular choice set. Several scholars have suggested that poor people should be more likely to spontaneously consider opportunity costs, because budget constraints should lead to an increased focus on trade-offs. We did not find support for this hypothesis in five high-powered experiments (total N = 2325). The experiments used different products (both material and experiential) with both high and low prices (from $8.50 to $249.99) and different methods of reminding participants of opportunity costs. High-income and low-income participants showed an equally strong decrease in willingness to buy when reminded of opportunity costs, implying that both the rich and the poor neglect opportunity costs. © 2017 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.

Stratification of women's sport in contemporary China.

PubMed

Xiong, Huan

2011-01-01

Since economic reform in the 1980s, Chinese sport has undergone an extraordinary transformation. The most distinguishing phenomenon is the rapid growth of mass sport at the grassroots level with increasing demands for physical activities in women's daily lives. The rapid growth of women's sports participation at the grassroots is deeply embedded in the process of social stratification as a result of the urbanisation of Chinese society. The purpose of this paper is to use the socialist, feminist and theoretical framework to explore how Chinese women's different economic, educational, domestic and cultural situations shape their sports values and patterns of participation, marking social boundaries in Chinese urban communities. Semi-structured interviews and observations were conducted with 60 female physical exercisers in sports clubs, parks and neighbourhood playgrounds. Documentary research was also applied as a complement method to the interview. The findings indicate that within different classes (middle class, working class and a group who were unemployed), many different opportunities for and limitations on women to participate in sport are noticed. Chinese women have not fully and equally utilised sports opportunities created by urbanisation. Most Chinese women still live within patriarchal arrangements. Consequently, they do not completely fulfil their ambitions in sport.

To elucidate the mechanism of the mechanically activated dissociation of chemical bonds between carboxymethylated amylose (CMA) and silane functionalized silicon dioxide, we have investigated the dissociation kinetics of the bonds connecting CMA to silicon oxide surfaces with density functional calculations including the effects of force, solvent polarizability, and pH. We have determined the activation energies, the pre-exponential factors, and the reaction rate constants of candidate reactions. The weakest bond was found to be the silyl ester bond between the silicon and the alkoxy oxygen atom. Under acidic conditions, spontaneous proton addition occurs close to the silyl ester such that neutralmore » reactions become insignificant. Upon proton addition at the most favored position, the activation energy for bond hydrolysis becomes 31 kJ mol{sup −1}, which agrees very well with experimental observation. Heterolytic bond scission in the protonated molecule has a much higher activation energy. The experimentally observed bi-exponential rupture kinetics can be explained by different side groups attached to the silicon atom of the silyl ester. The fact that different side groups lead to different dissociation kinetics provides an opportunity to deliberately modify and tune the kinetic parameters of mechanically activated bond dissociation of silyl esters.« less

Comparing Professional Values of Sophomore and Senior Baccalaureate Nursing Students.

Posluszny, Laura; Hawley, Diane A

2017-09-01

The 2015 American Nurses' Association Code of Ethics reinforces professional values in nursing, and nurse educators may need evidence of their students' professional development. Using the Nurses Professional Values Scale-Revised (NPVS-R), researchers examined two questions: What is the relative importance of professional values (i.e., caring, trust, justice, activism, and professionalism) for beginning and graduating baccalaureate nursing students, and are there differences in professional values between these students? New and graduating nursing students in the current study had well-developed professional values. Sophomore-level nursing students viewed trust, caring, and justice as significantly more important than activism. Senior-level students perceived trust as significantly more important than activism and professionalism. Although total NPVS-R scores did not differ significantly between cohorts, senior-level students did score significantly higher on activism than sophomore-level students. With the revised Code, nurse educators may reevaluate the ethics curriculum. This study suggests opportunity for strengthening values beyond the nurse-client relationship, such as activism and professionalism. [J Nurs Educ. 2017;56(9):546-550.].

2014-12-12

Measuring mobility is critical for understanding neighborhood influences on older adults' health and functioning. Global Positioning Systems (GPS) may represent an important opportunity to measure, describe, and compare mobility patterns in older adults. We generated three types of activity spaces (Standard Deviation Ellipse, Minimum Convex Polygon, Daily Path Area) using GPS data from 95 older adults in Vancouver, Canada. Calculated activity space areas and compactness were compared across sociodemographic and resource characteristics. Area measures derived from the three different approaches to developing activity spaces were highly correlated. Participants who were younger, lived in less walkable neighborhoods, had a valid driver's license, had access to a vehicle, or had physical support to go outside of their homes had larger activity spaces. Mobility space compactness measures also differed by sociodemographic and resource characteristics. This research extends the literature by demonstrating that GPS tracking can be used as a valuable tool to better understand the geographic mobility patterns of older adults. This study informs potential ways to maintain older adult independence by identifying factors that influence geographic mobility.

Obesity Policy Action framework and analysis grids for a comprehensive policy approach to reducing obesity.

PubMed

Sacks, G; Swinburn, B; Lawrence, M

2009-01-01

A comprehensive policy approach is needed to control the growing obesity epidemic. This paper proposes the Obesity Policy Action (OPA) framework, modified from the World Health Organization framework for the implementation of the Global Strategy on Diet, Physical Activity and Health, to provide specific guidance for governments to systematically identify areas for obesity policy action. The proposed framework incorporates three different public health approaches to addressing obesity: (i) 'upstream' policies influence either the broad social and economic conditions of society (e.g. taxation, education, social security) or the food and physical activity environments to make healthy eating and physical activity choices easier; (ii) 'midstream' policies are aimed at directly influencing population behaviours; and (iii) 'downstream' policies support health services and clinical interventions. A set of grids for analysing potential policies to support obesity prevention and management is presented. The general pattern that emerges from populating the analysis grids as they relate to the Australian context is that all sectors and levels of government, non-governmental organizations and private businesses have multiple opportunities to contribute to reducing obesity. The proposed framework and analysis grids provide a comprehensive approach to mapping the policy environment related to obesity, and a tool for identifying policy gaps, barriers and opportunities.

Cultural Differences in Opportunity Cost Consideration

Zhang, Ning; Ji, Li-Jun; Li, Ye

2017-01-01

Two studies were conducted to investigate cultural differences in opportunity cost consideration between Chinese and Euro-Canadians. Opportunity cost is defined as the cost of a benefit that must be forgone in order to pursue a better alternative (Becker et al., 1974). In both studies, participants read about hypothetical purchase scenarios, and then decided whether they would buy a certain product. Opportunity cost consideration was measured in two ways: (1) participants' thoughts pertaining to other (nonfocal) products while making decisions; (2) participants' decisions not to buy a focal product (Study 1) or a more expensive product (Study 2). Across both indexes, we found that after controlling for individual difference variables and amount of pocket money, Chinese participants in China considered financial opportunity cost more than Euro-Canadians in Study 1. Similar results were observed in Study 2 when comparing Chinese in Canada with Euro-Canadians However, the cultural effect on opportunity cost consideration was confounded by family income in Study 2. Implications for resource management, limitations of the current research and directions for future research are discussed. PMID:28184202

Development of a Novel Method for in vivo Determination of Activation Energy of Glucose Transport Across S. cerevisiae Cellular Membranes. A Biosensor-like Approach

2009-01-01

Whereas biosensors have been usually proposed as analytical tools, used to investigate the surrounding media pursuing an analytical answer, we have used a biosensor-like device to characterize the microbial cells immobilized on it. We have studied the kinetics of transport and degradation of glucose at different concentrations and temperatures. When glucose concentrations of 15 and 1.5 mM were assayed, calculated activation energies were 25.2 and 18.4 kcal mol−1, respectively, in good agreement with previously published data. The opportunity and convenience of using Arrhenius plots to estimate the activation energy in metabolic-related processes is also discussed. PMID:22573975

How community environment shapes physical activity: perceptions revealed through the PhotoVoice method.

A growing body of evidence shows that community environment plays an important role in individuals' physical activity engagement. However, while attributes of the physical environment are widely investigated, sociocultural, political, and economic aspects of the environment are often neglected. This article helps to fill these knowledge gaps by providing a more comprehensive understanding of multiple dimensions of the community environment relative to physical activity. The purpose of this study was to qualitatively explore how people's experiences and perceptions of their community environments affect their abilities to engage in physical activity. A PhotoVoice method was used to identify barriers to and opportunities for physical activity among residents in four communities in the province of Alberta, Canada, in 2009. After taking pictures, the thirty-five participants shared their perceptions of those opportunities and barriers in their community environments during individual interviews. Using the Analysis Grid for Environments Linked to Obesity (ANGELO) framework, themes emerging from these photo-elicited interviews were organized in four environment types: physical, sociocultural, economic, and political. The data show that themes linked to the physical (56.6%) and sociocultural (31.4%) environments were discussed more frequently than the themes of the economic (5.9%) and political (6.1%) environments. Participants identified nuanced barriers and opportunities for physical activity, which are illustrated by their quotes and photographs. The findings suggest that a myriad of factors from physical, sociocultural, economic, and political environments influence people's abilities to be physically active in their communities. Therefore, adoption of a broad, ecological perspective is needed to address the barriers and build upon the opportunities described by participants to make communities more healthy and active.

1980-01-01

Atlantic Brant Branta bernicla hrota in Barnegat Bay, New Jersey, have established a commensal feeding relationship with man. Small flocks feed 3-5 m from clam fishermen on Zostera torn from the sea bottom by the fishing activities. Background material on the availability and digestibility of different brant foods is presented. This commensalism gives the Brant an efficient food gathering opportunity and permits them to exploit Zostera which might otherwise be unavailable to them.

Peer assisted learning in the clinical setting: an activity systems analysis.

PubMed

Bennett, Deirdre; O'Flynn, Siun; Kelly, Martina

2015-08-01

Peer assisted learning (PAL) is a common feature of medical education. Understanding of PAL has been based on processes and outcomes in controlled settings, such as clinical skills labs. PAL in the clinical setting, a complex learning environment, requires fresh evaluation. Socio-cultural theory is proposed as a means to understand educational interventions in ways that are practical and meaningful. We describe the evaluation of a PAL intervention, introduced to support students' transition into full time clinical attachments, using activity theory and activity systems analysis (ASA). Our research question was How does PAL transfer to the clinical environment? Junior students on their first clinical attachments undertook a weekly same-level, reciprocal PAL activity. Qualitative data was collected after each session, and focus groups (n = 3) were held on completion. Data was analysed using ASA. ASA revealed two competing activity systems on clinical attachment; Learning from Experts, which students saw as the primary function of the attachment and Learning with Peers, the PAL intervention. The latter took time from the first and was in tension with it. Tensions arose from student beliefs about how learning takes place in clinical settings, and the importance of social relationships, leading to variable engagement with PAL. Differing perspectives within the group were opportunities for expansive learning. PAL in the clinical environment presents challenges specific to that context. Using ASA helped to describe student activity on clinical attachment and to highlight tensions and contradictions relating PAL in that setting. Planning learning opportunities on clinical placements, must take account of how students learn in workplaces, and the complexity of the multiple competing activity systems related to learning and social activities.

Given the need to find more opportunities for physical activity within the elementary school day, this study was designed to asses the impact of I-CAN!, active lessons on: 1) student physical activity (PA) outcomes via accelerometry; and 2) socioeconomic status (SES), race, sex, body mass index (BMI), or fitness as moderators of this impact. Participants were 2,493 fourth grade students (45.9% male, 45.8% white, 21.7% low SES) from 28 central Texas elementary schools randomly assigned to intervention (n=19) or control (n=9). Multilevel regression models evaluated the effect of I-CAN! on PA and effect sizes were calculated. The moderating effects of SES, race, sex, BMI, and fitness were examined in separate models. Students in treatment schools took significantly more steps than those in control schools (β = 125.267, SE = 41.327, p = .002, d = .44). I-CAN! had a significant effect on MVPA with treatment schools realizing 80% (β = 0.796, SE =0.251, p = .001; d = .38) more MVPA than the control schools. There were no significant school-level differences on sedentary behavior (β = -0.177, SE = 0.824, p = .83). SES, race, sex, BMI, and fitness level did not moderate the impact of active learning on step count and MVPA. Active learning increases PA within elementary students, and does so consistently across demographic sub-groups. This is important as these sub-groups represent harder to reach populations for PA interventions. While these lessons may not be enough to help children reach daily recommendations of PA, they can supplement other opportunities for PA. This speaks to the potential of schools to adopt policy change to require active learning.

The Hungry Stomach: Physiology, Disease, and Drug Development Opportunities

Sanger, Gareth J.; Hellström, Per M.; Näslund, Erik

2010-01-01

During hunger, a series of high-amplitude contractions of the stomach and small intestine (phase III), which form part of a cycle of quiescence and contractions (known as the migrating motor complex, MMC), play a “housekeeping” role prior to the next meal, and may contribute toward the development of hunger. Several gastrointestinal (GI) hormones are associated with phase III MMC activity, but currently the most prominent is motilin, thought to at least partly mediate phase III contractions of the gastric MMC. Additional GI endocrine and neuronal systems play even more powerful roles in the development of hunger. In particular, the ghrelin-precursor gene is proving to have a complex physiology, giving rise to three different products: ghrelin itself, which is formed from a post-translational modification of des-acyl-ghrelin, and obestatin. The receptors acted on by des-acyl-ghrelin and by obestatin are currently unknown but both these peptides seem able to exert actions which oppose that of ghrelin, either indirectly or directly. An increased understanding of the actions of these peptides is helping to unravel a number of different eating disorders and providing opportunities for the discovery of new drugs to regulate dysfunctional gastric behaviors and appetite. To date, ghrelin and motilin receptor agonists and antagonists have been described. The most advanced are compounds which activate the ghrelin and motilin receptors which are being progressed for disorders associated with gastric hypomotility. PMID:21927604

Psychological Assessment Training in Clinical Psychology Doctoral Programs.

2017-01-01

We surveyed American Psychological Association-accredited clinical psychology doctoral programs' (n = 83) training in psychological assessment-specifically, their coverage of various assessment topics and tests in courses and practica, and whether the training was optional or required. We report results overall and separately per training model (clinical science, scientist-practitioner, and practitioner-focused). Overall, our results suggest that psychological assessment training is as active, or even more active, than in previous years. Areas of increased emphasis include clinical interviewing and psychometrics; multimethod, outcomes, health, and collaborative or therapeutic assessment; and different types of cognitive and self-report personality tests. All or almost all practice-focused programs offered training with the Thematic Apperception Test and Rorschach compared to about half of the scientist-practitioner programs and a third of the clinical science programs. Although almost all programs reported teaching multimethod assessment, what constitutes different methods of assessing psychopathology should be clarified in future studies because many programs appear to rely on one method-self-report (especially clinical science programs). Although doctoral programs covered many assessment topics and tests in didactic courses, there appears to be a shortage of program-run opportunities for students to obtain applied assessment training. Finally, we encourage doctoral programs to be familiar with (a) internships' assessment expectations and opportunities, (b) the professional guidelines for assessment training, and (c) the American Psychological Association's requirements for preinternship assessment competencies.

GateWay Community College Water Resources Program Partnerships: An Opportunity for Program Success and Collaboration

GateWay Community College Water Resources Technologies (WRT) Program offers Certificate of Completions and Associate Degrees on Hydrologic Studies, Water Treatment and Wastewater Treatment. The program has been in existence since 1998 and has gone through several updates to meet the demand for professionals in those areas. The program includes theoretical and practical hands-on training in the monitoring of water quality and quantity as well as in water and industrial wastewater treatment. The WRT program offers online, face-to-face, and hybrid courses to address different student's needs for training. The program only Full-time faculty is supported by 15 adjunct- faculty professionals. Adjunct faculty is usually hired from a wide variety of professional people already working in the industry that have shown interest on teaching. Adjunct faculty also provide free tutoring to the WRT students when they are not teaching courses. The college Learning Center provides funding to support these tutoring activities. The program has an active Advisory Committee that provides guidance and recommends program changes to meet their training needs. This Advisory Committee is made of professionals from different federal, state, county agencies, and municipalities, private industry and consulting companies in the area. The Advisory Committee meets every year to provide feedback to GateWay on curriculum changes and commit to potential internship opportunities for the WRT students. Those internships (or voluntary work) are paid directly by the municipalities or agencies or can be paid by the GateWay WRT program. These internship jobs provides with an opportunity to actively promote the WRT program throughout the valley. The GateWay WRT program considers the Advisory Committee an essential component for the program success: the committee supports the program in recommending and acquiring the latest field equipment needed for the hands-on training. One of the main WRT program objective is to utilize the latest field equipment that will be used by the students when they incorporate into the job market place. The GateWay WRT program is always looking for articulation opportunities with four-year universities. Although not all WRT students are interested in pursuing a four-year degree as part of their professional development, some students welcome this opportunity. GateWay WRT program is finalizing articulation agreements with the University of Arizona's Hydrology and Water Resources Program as well as with the Arizona State University Environmental Management program. Also, the WRT program is trying to internationalize its curriculum by establishing contacts with similar programs in other countries. The University of Guanajuato from Mexico has shown interest in exchanging not only students but also faculty through this process. The WRT program puts emphasis in service learning activities by collaborating and helping community groups such the Lindon Park Neighborhood Association and The Environmental Community Outreach Association. Both groups are in charge of disseminating environmental information to the community regarding superfund site issues. The WRT program has supported several paid internships to increase the community awareness on these technical issues.

A systematic study of the induced radioactivity of the Long Duration Exposure Facility (LDEF) is being carried out in order to gather information about the low earth orbit radiation environment and its effects on materials. The large mass of the LDEF spacecraft, its stabilized configuration, and long mission duration have presented an opportunity to determine space radiation-induced radioactivities with a precision not possible before. Data presented include preliminary activities for steel and aluminum structural samples, and activation subexperiment foils. Effects seen in the data show a clear indication of the trapped proton anisotropy in the South Atlantic Anomaly and suggest contributions from different sources of external radiation fluxes.

Integration Science and Technology of Silicon-Based Ceramics and Composites:Technical Challenges and Opportunities

NASA Technical Reports Server (NTRS)

Singh, M.

2013-01-01

Ceramic integration technologies enable hierarchical design and manufacturing of intricate ceramic and composite parts starting with geometrically simpler units that are subsequently joined to themselves and/or to metals to create components with progressively higher levels of complexity and functionality. However, for the development of robust and reliable integrated systems with optimum performance for high temperature applications, detailed understanding of various thermochemical and thermomechanical factors is critical. Different technical approaches are required for the integration of ceramic to ceramic and ceramic to metal systems. Active metal brazing, in particular, is a simple and cost-effective method to integrate ceramic to metallic components. Active braze alloys usually contain a reactive filler metal (e.g., Ti, Cr, V, Hf etc) that promotes wettability and spreading by inducing chemical reactions with the ceramics and composites. In this presentation, various examples of brazing of silicon nitride to themselves and to metallic systems are presented. Other examples of joining of ceramic composites (C/SiC and SiC/SiC) using ceramic interlayers and the resulting microstructures are also presented. Thermomechanical characterization of joints is presented for both types of systems. In addition, various challenges and opportunities in design, fabrication, and testing of integrated similar (ceramic-ceramic) and dissimilar (ceramic-metal) material systems will be discussed. Potential opportunities and need for the development of innovative design philosophies, approaches, and integrated system testing under simulated application conditions will also be presented.

In order to improve healthy behaviours among rural children in their early years, a physical activity and healthy eating intervention (Healthy Start - Départ Santé) was implemented in rural childcare centres throughout Saskatchewan. The objective of the current study was to evaluate the impact of a multimodal physical activity and healthy eating intervention on educators' provision of opportunities for children to improve their physical activity levels, fundamental movement skills and healthy eating behaviours. Six childcare centres (three Francophone and three Anglophone) located in five different rural and semi-rural communities in Saskatchewan participated in this intervention. A total of 69 children with a mean age of 4 years 9 months, and 19 female early childhood educators. Guided by an ecological framework, we implemented a population health controlled intervention, using a wait list control design (48 weeks delayed intervention), and evaluated its impact in rural childcare centres. Mixed methods were employed to determine the effectiveness of the intervention. Overall, educators felt that the intervention supported the provision of physical activity and healthy eating opportunities for children. Increases in children's physical activity levels were reported following the intervention. The lessons learned in this study can be used to improve the Healthy Start - Départ Santé intervention so that its implementation can be effectively expanded to childcare centres within and outside Saskatchewan, in turn, supporting the healthy development of early years (0-5) children in the province and beyond.

Boston public housing residents are more likely to report fair or poor health status, been diagnosed with obesity, and to be physically inactive compared with other Boston residents (Digenis-Bury, Brooks, Chen, Ostrem, & Horsburgh, 2008 ). Little is known about perceptions of and opportunities for healthy eating and physical activity in this population. We conducted eight focus groups at public housing developments to explore residents' views regarding opportunities and barriers to healthy eating and physical activity. Sixty-seven English- and Spanish-speaking residents participated. Transcripts were analyzed using qualitative content analysis. All residents described the challenge of balancing considerations of food quality, access, and affordability. Other findings included underutilized nutritional resources; abundant availability of unhealthy food; and economic and structural barriers to exercise. Transportation-related challenges were a dominant theme. Building opportunities for physical activity and providing access to affordable and quality food choices may be important interventions for promoting health among public housing residents.

Differences in psychosocial determinants of physical activity in older adults participating in organised versus non-organised activities.

With the introduction of the new consensus on 30 minutes of moderate physical activity preferably on all days of the week, exercise implemented into daily activities is promoted whereas structured activity programs lose importance. Activity levels of most older people don't come up with current recommendations. Therefore strategies to enhance attendance of older adults in physical activities should be developed. Group programs may be more effective in changing exercise behaviour of older adults than non-supervised physical activity. The purpose of this study was to investigate the differences in level of activity and psychosocial determinants of physical activity between seniors involved in an exercise class and seniors not engaged in any organised physical activity. Seventy-five elderly who were currently involved in structured exercise classes and 75 elderly who did not participate in any organised physical activity during the previous year were recruited in senior citizens' centres and were asked to fill out a questionnaire. Subjects involved in an exercise program had higher levels of activity and reported more social influences and higher self-efficacy compared to the respondents practising on an individual basis. No differences were found in perceived barriers or benefits. Exercising in a group program gives the opportunity to accumulate some extra physical activity and positively affects the level of activity outside the program. Stimulating older adults to join a structured activity program in the company of family or friends in order to enhance supporting social influences and perceived competence could be an important intervention strategy.

Evidence for Opportunity Cost Neglect in the Poor

Abstract People often neglect opportunity costs: They do not fully take into account forgone alternatives outside of a particular choice set. Several scholars have suggested that poor people should be more likely to spontaneously consider opportunity costs, because budget constraints should lead to an increased focus on trade‐offs. We did not find support for this hypothesis in five high‐powered experiments (total N = 2325). The experiments used different products (both material and experiential) with both high and low prices (from $8.50 to $249.99) and different methods of reminding participants of opportunity costs. High‐income and low‐income participants showed an equally strong decrease in willingness to buy when reminded of opportunity costs, implying that both the rich and the poor neglect opportunity costs. © 2017 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.

Century long assessment of herbaceous plants' physiological responses to climate change in Switzerland

2017-04-01

The isotopic analysis of archived plant material offers the exceptional opportunity to reconstruct the physiological activity of plants over long time periods and thus, to assess plant responses to environmental changes during the last centuries. In addition, the stable isotope analysis of herbarium samples offers the opportunity to reconstruct the physiological processes of a large range of different plant species and from different environments. Interestingly, only few studies have to date assessed these archives. We will present a novel analysis of leaf nitrogen, oxygen and carbon isotope ratios of more than a thousand herbarium specimens collected since 1800 until present from the unique herbaria hold at the University of Basel. The objective of our study was to assess century-long physiological responses of herbaceous plant species from different plant functional groups and along an altitudinal gradient in Switzerland. The goal of our study was to determine with our investigations the long-term responses of plants to climate change. Such investigations are important as they allow to assess long-term processes of acclimation and adaptation in plants to global enviromental change. In our study we found that herbaceous plants have increased their intrinsic water use efficiency in response to increasing atmospheric CO2 concentration but this increment was higher in plants from higher altitudes, due to the higher efficiency of CO2 assimilation of alpine plants compared to plants from lowlands. There were also differences among functional groups, with grasses and forbs showing the highest increments. In addition, herbaceous plants showed a decreasing trend with time in their N isotopic composition, which may indicate progressive N limitation due to higher biological activity with increasing atmospheric CO2 concentration.

A recent acceleration of model-data synthesis activities has leveraged many terrestrial carbon (C) datasets, but utilization of soil respiration (RS) data has not kept pace with other types such as eddy covariance (EC) fluxes and soil C stocks. Here we argue that RS data, including non-continuous measurements from survey sampling campaigns, have unrealized value and should be utilized more extensively and creatively in data synthesis and modeling activities. We identify three major challenges in interpreting RS data, and discuss opportunities to address them. The first challenge is that when RS is compared to ecosystem respiration (RECO) measured from EC towers,more » it is not uncommon to find substantial mismatch, indicating one or both flux methodologies are unreliable. We argue the most likely cause of mismatch is unreliable EC data, and there is an unrecognized opportunity to utilize RS for EC quality control. The second challenge is that RS integrates belowground heterotrophic (RH) and autotrophic (RA) activity, whereas modelers generally prefer partitioned fluxes, and few models include an explicit RS output. Opportunities exist to use the total RS flux for data assimilation and model benchmarking methods rather than less-certain partitioned fluxes. Pushing for more experiments that not only partition RS but also monitor the age of RA and RH, as well as for the development of belowground RA components in models, would allow for more direct comparison between measured and modeled values. The third challenge is that soil respiration is generally measured at a very different resolution than that needed for comparison to EC or ecosystem- to global-scale models. Measuring soil fluxes with finer spatial resolution and more extensive coverage, and downscaling EC fluxes to match the scale of RS, will improve chamber and tower comparisons. Opportunities also exist to estimate RH at regional scales by implementing decomposition functional types, akin to plant functional types. We conclude by discussing the benefits that wide use of RS data will bring to model development, and database developments that will make RS data more robust, useful, and broadly available to the research community.« less

Regular physical activity is a health promotion and disease prevention behavior. Of all demographic groups, low-income women report the lowest levels of physical activity. The purpose of this study was to test an intervention aimed at reducing community environmental barriers to physical activity in low-income women. The research design was mixed methodology: (1) quantitative (quasi-experimental, pretest-posttest, cohort design in which no treatment partitioning was possible) and (2) qualitative (focus groups). The setting was a church-sponsored community center centrally located in a low-income urban neighborhood. The comparison group was recruited first followed by the intervention group to control for setting. The sample consisted of 104 women (comparison group, n = 53; intervention group, n = 51) between the ages of 18 and 63 years who were residents of neighborhoods served by the community center. No between-group differences were found for physical activity behavior. Significant between-group differences in cholesterol (P = .007) and perception of physical activity (P = .033) were observed. Significant intervention group increases from pretest to posttest were found related to advanced registered nurse practitioner support, friend support, and more positive physical activity environment at the community center. Qualitative data supported and enriched the quantitative data. Physical activity levels were not significantly different between the groups. In a sample of low-income women who have multiple barriers, improving attitudes, expanding their knowledge of community resources, and providing physical activity opportunities in their neighborhoods are important intermediate steps toward initiation and maintenance of regular physical activity.

There has been a considerable amount of research that documents how women and men spend their time in different work and home tasks. We examine how much time professional women and men spend in paid and unpaid work and how this relates to their participation in different leisure activities. We also explore whether time in paid and unpaid work has gender-specific effects on leisure participation. In examining these issues, we rely on data from lawyers working in different legal settings. Our results show that, as hypothesized, men report more time in paid work and leisure whereas women devote more time to housework and childcare. An unexpected finding is that the time men spend in housework or childcare is either unrelated or positively related to their leisure participation. These results suggest that men's greater overall opportunities for leisure compared with women's appear to stem from the unanticipated relationships between men's involvement in housework and childcare and their leisure activities. We raise several possible explanations for these findings.

Identifying Differences Between Off-Highway Vehicle (OHV) and Non-OHV User Groups for Recreation Resource Planning

Off-highway vehicle (OHV) riding is among the fastest growing recreational activities in the United States. However, little research exists about the central components of outcomes-focused management (OFM) as it relates to motorized recreation. Utilizing a two-activity dichotomy, OHV and non-OHV centric user groups were compared on several key concepts associated with OFM, including desired experiences, perceived and desired recreation opportunity spectrum-type settings, and intentional behaviors (i.e., place-protective behavior, spending-time intentions) toward potential changes in settings. Results indicated that the two groups were different in terms of intensity and relative rankings of their perceived experiences and settings. Although both groups preferred social bonding, stress relief, nostalgia and learning experiences, the OHV user group ranked using equipment and achieving physical fitness experiences as more important than the non-OHV group. The non-OHV user group preferred enjoying nature and solitude/tranquility experiences more strongly than the OHV user group. Further analysis found that both groups perceived settings that they recreated in to be pristine and preferred such conditions, and both groups preferred moderate levels of rules and regulations. Finally, the OHV user group was more reactive to rules and regulations, while the non-OHV user group expressed stronger intentions to protect the environmental quality of recreation areas. The results suggest that planners and managers who understand OHV user's perceptions and behaviors could provide enhanced recreation opportunities potentially providing additional beneficial outcomes for motorized and non-motorized groups in spatially different zones. Additional implications for planners and managers and future studies are discussed.

Physical fitness and levels of physical activity in people with severe mental illness: a cross-sectional study.

Physical fitness is a crucial variable in people with severe mental illness as these people could be more independent and improve their job opportunities. The present study compared the physical fitness of physically active and inactive people with severe mental illness. Physical fitness was evaluated in sixty-two people with severe mental illness using 11 physical tests that include strength, flexibility, balance and aerobic condition. Significant differences were found between both groups in muscle strength (handgrip test) and balance (single leg balance test and functional reach) with better performance in the group of physically active people. The results of the present study suggest that physical fitness (strength and balance) is higher in people with severe mental illness who practise regular physical activity that those who are inactive people. Physical active people may have a reduced risk of falls and fractures due to their higher levels of physical fitness.

Parks provide opportunities for people to engage in activities that can promote physical and emotional well-being. Using focus groups and personal interviews conducted in select neighborhoods of a Northeastern city with a high rate of obesity, we examined perceptions of barriers and facilitators regarding the use of parks and park features that would promote physical activity among Latina women ( N = 39). Foreign-born Latinas emphasized the environmental characteristics of parks and the types of amenities that can support preferred cultural and social activities, while U.S.-born Latinas emphasized the use of parks for physical activity and weight management. Most striking were the different ways in which foreign-born participants conceptualized parks as sociocultural family centers, extending more common conceptualizations centered on exercise or individual health gain. These findings suggest the need for new policies that incorporate culturally specific park programming to promote national goals of increasing levels of physical activity for health.

The major challenge in laboratory teaching is the application of abstract concepts in simple and direct practical lessons. However, students rarely have the opportunity to participate in a laboratory that combines practical learning with a realistic research experience. In the Biomedical Engineering career, we offer short and optional courses to complement studies for students as they initiate their Graduation Project. The objective of these theoretical and practical courses is to introduce students to the topics of their projects. The present work describes an experience in electrophysiology to teach undergraduate students how to extract cortical information using electrocorticographic techniques. Students actively participate in some parts of the experience and then process and analyze the data obtained with different signal processing tools. In postlaboratory evaluations, students described the course as an exceptional opportunity for students interested in following a postgraduate science program and fully appreciated their contents.

2011-12-01

Building students' ability to transfer physics fundamentals to real-world applications establishes a deeper understanding of underlying concepts while enhancing student interest. Forensic science offers a great opportunity for students to apply physics to highly engaging, real-world contexts. Integrating these opportunities into inquiry-based problem solving in a team environment provides a terrific backdrop for fostering communication, analysis, and critical thinking skills. One such activity, inspired jointly by the museum exhibit "CSI: The Experience"2 and David Bonner's TPT article "Increasing Student Engagement and Enthusiasm: A Projectile Motion Crime Scene,"3 provides students with three different crime scenes, each requiring an analysis of projectile motion. In this lesson students socially engage in higher-order analysis of two-dimensional projectile motion problems by collecting information from 3-D scale models and collaborating with one another on its interpretation, in addition to diagramming and mathematical analysis typical to problem solving in physics.

This report outlines current Small Business Innovation Research (SBIR) Post-Phase II opportunity contract award results for the SBIR technology program from 2007 to 2011 for NASA's Aeronautics Research Mission Directorate (ARMD), Human Exploration and Operations Mission Directorate (HEOMD), Science Mission Directorate (SMD), and Space Technology Mission Directorate (STMD). The report provides guidelines for incorporating SBIR technology into NASA programs and projects and provides a quantitative overview of the post-Phase II award patterns that correspond with each mission directorate at NASA Glenn Research Center (GRC). In recent years, one of NASA's goals has been to not only transfer SBIR technologies to commercial industries, but to ensure that NASA mission directorates incorporate SBIR technologies into their program and project activities. Before incorporating technologies into MD programs, it is important to understand each mission directorate structure because each directorate has different objectives and needs. The directorate program structures follow.

Recently developed methods for functional MRI at the resolution of cortical layers (laminar fMRI) offer a novel window into neurophysiological mechanisms of cortical activity. Beyond physiology, laminar fMRI also offers an unprecedented opportunity to test influential theories of brain function. Specifically, hierarchical Bayesian theories of brain function, such as predictive coding, assign specific computational roles to different cortical layers. Combined with computational models, laminar fMRI offers a unique opportunity to test these proposals noninvasively in humans. This review provides a brief overview of predictive coding and related hierarchical Bayesian theories, summarises their predictions with regard to layered cortical computations, examines how these predictions could be tested by laminar fMRI, and considers methodological challenges. We conclude by discussing the potential of laminar fMRI for clinically useful computational assays of layer-specific information processing. Copyright © 2017 Elsevier Inc. All rights reserved.

2010-07-01

The World Health Organization project on the Global Burden of Disease quantifies the main causes of premature death and disability. Changing patterns of physical activity, diet, and alcohol and tobacco consumption are producing a growing burden of noncommunicable disease in low-and middle-income countries. This article focuses on a different group of health risks: major health emergencies that do not respect national borders and have an impact on health and the determinants of health such as housing, access to food and water, and other life essentials. Health emergencies, including accidents and natural events, are described, and data on disasters in the Middle East are presented. Disaster response is contrasted with disaster prevention, and disaster risk reduction is discussed in the context of vulnerability, climate change, and sustainable development. Finally, the international policy context of disaster risk reduction is discussed along with opportunities for multidisciplinary and multiinstitutional collaboration and research.

Summer day camps (SDCs) serve 14 million children yearly in the U.S. and aim to provide participating children with 60 minutes of moderate-to-vigorous physical activity (MVPA). This study evaluated an intervention designed to increase the percent of children meeting this MVPA guideline. Two-group, pre-post quasi-experimental. Twenty SDCs serving 1,830 children aged 5-12 years were assigned to MVPA intervention (n = 10) or healthy eating attention control (n = 10). The STEPs (Strategies to Enhance Practice) intervention is a capacity-building approach grounded in the Theory of Expanded, Extended and Enhanced Opportunities. Camp leaders and staff receive training to expand (e.g., introduction of activity breaks/active field trips), extend (e.g., schedule minimum of 3 hours/day for PA opportunities), and enhance (e.g., maximize MVPA children accumulate during schedule activity) activity opportunities. Camps in the comparison condition received support for improving the types of foods/beverages served. Percent of children accumulating the 60min/d MVPA guideline at baseline (summer 2015) and post-test (summer 2016) measured via wrist-accelerometry. Multilevel logistic regression conducted fall 2016 indicated boys and girls attending intervention SDCs were 2.04 (95CI = 1.10,3.78) and 3.84 (95CI = 2.02,7.33) times more likely to meet the 60min/d guideline compared to boys and girls attending control SDCs, respectively. This corresponded to increases of +10.6% (78-89%) and +12.6% (69-82%) in the percentage of boys and girls meeting the guideline in intervention SDCs, respectively. Boys in comparison SDCs increased by +1.6% (81-83%) and girls decreased by -5.5% (76-71%). Process data indicated intervention SDCs successfully extended and enhanced PA opportunities, but were unable to expand PA opportunities, compared to control SDCs. Although substantial proportions of children met the MVPA guideline at baseline, no SDCs ensured all children met the guideline. This intervention demonstrated that, with support, SDCs can help all children in attendance to accumulate their daily recommended 60min MVPA. ClinicalTrials.gov NCT02161809.

2013-06-01

Although girls are generally less physically active than boys, some girls regularly engage in high levels of physical activity (PA); however, very little is known about these girls and how they differ from those who are less physically active. This study examined the PA behavior and related characteristics of highly active adolescent girls and compared them with those who are less active. Data from 1,866 eighth-grade girls from six field centers across the United States participating in the Trial of Activity for Adolescent Girls (TAAG) were included in the present analysis. Mixed-model analysis of variance examined differences in sociodemographic, anthropometric, psychosocial, and physical activity (accelerometry and self-report) variables between high- and low-active girls; effect sizes were calculated for the differences. High-active girls were taller, had lower body mass indices and body fat, and were less sedentary. High-active girls scored higher on self-efficacy, enjoyment of PA, self-management strategies, outcome-expectancy value, and support from family and friends than low-active girls. Low-active girls participated in more leisure time and educational sedentary activities than high-active girls. High-active girls participated in more PA classes/lessons outside of school, team sports, and individual sports. They were also more likely to participate in sports in an organized setting in the community or at school than low-active girls. Health promotion efforts should focus on decreasing the amount of time girls spend in sedentary activities and replacing that time with organized PA opportunities; such efforts should seek to minimize perceived barriers and increase self-efficacy and support for PA.

Individual differences in trait motivational reactivity influence children and adolescents' responses to pictures of taboo products.

PubMed

Lang, Annie; Lee, Sungkyoung

2014-09-01

This study examined how children and adolescents respond to pictures of products whose use, for them, is socially or legally restricted (e.g., beer, liquor, cigarettes). It was theorized and found that these pictures, referred to as taboo, elicit an automatic motivational activation whose direction and intensity are influenced by age and individual differences in defensive system activation. Results show that 11-12-year-old children demonstrate primarily aversive responses to taboo products, 13-15-year-old children have less aversive responses, and 16-17-year-old children have mixed appetitive and aversive motivational responses. Further, those with high defensive system activation show larger aversive and smaller appetitive responses across the age groups. These results suggest that placing pictures of these products in prevention messages may work for the prevention goal of reduced experimentation and risk in younger children but against the prevention goal for the older children who may be more likely to be exposed to opportunities for experimentation and use.

To develop an assessment method of active aging for research on older people. A multiphase process that included drafting by an expert panel, a pilot study for item analysis and scale validity, a feedback study with focus groups and questionnaire respondents, and a test-retest study. Altogether 235 people aged 60 to 94 years provided responses and/or feedback. We developed a 17-item University of Jyvaskyla Active Aging Scale with four aspects in each item (goals, ability, opportunity, and activity; range 0-272). The psychometric and item properties are good and the scale assesses a unidimensional latent construct of active aging. Our scale assesses older people's striving for well-being through activities pertaining to their goals, abilities, and opportunities. The University of Jyvaskyla Active Aging Scale provides a quantifiable measure of active aging that may be used in postal questionnaires or interviews in research and practice.

Competition in the Dutch hospital sector: an analysis of health care volume and cost.

2017-03-01

This paper evaluates the impact of market competition on health care volume and cost. At the start of 2005, the financing system of Dutch hospitals started to be gradually changed from a closed-end budgeting system to a non-regulated price competitive prospective reimbursement system. The gradual implementation of price competition is a 'natural experiment' that provides a unique opportunity to analyze the effects of market competition on hospital behavior. We have access to a unique database, which contains hospital discharge data of diagnosis treatment combinations (DBCs) of individual patients, including detailed care activities. Difference-in-difference estimates show that the implementation of market-based competition leads to relatively lower total costs, production volume and number of activities overall. Difference-in-difference estimates on treatment level show that the average costs for outpatient DBCs decreased due to a decrease in the number of activities per DBC. The introduction of market competition led to an increase of average costs of inpatient DBCs. Since both volume and number of activities have not changed significantly, we conclude that the cost increase is likely the result of more expensive activities. A possible explanation for our finding is that hospitals look for possible efficiency improvements in predominantly outpatient care products that are relatively straightforward, using easily analyzable technologies. The effects of competition on average cost and the relative shares of inpatient and outpatient treatments on specialty level are significant but contrary for cardiology and orthopedics, suggesting that specialties react differently to competitive incentives.

An Analysis of NSF Geosciences Research Experience for Undergraduate Site Programs from 2009 through 2011

The Research Experience for Undergraduate (REU) Program at the U.S. National Science Foundation (NSF) provides U.S. undergraduate students from any college or university the opportunity to conduct research at a different institution and gain a better understanding of research career pathways. The Geosciences REU Sites foster research opportunities in areas closely aligned with geoscience programs, particularly those related to earth, atmospheric and ocean sciences. The aim of this paper is to provide an overview of the Geosciences REU Site programs run in 2009 through 2011. A survey requesting information on recruitment methods, student demographics, enrichment activities, and fields of research was sent to the Principal Investigators of each of the active REU Sites. Over 70% of the surveys were returned with the requested information from about 50 to 60 sites each year. The internet is the most widely used mechanism to recruit participants, with personal communication as the second most important recruiting tool. The admissions rate for REU Sites in Geosciences varies from less than 10% to 50%, with the majority of participants being rising seniors and juniors. Many of the participants come from non-PhD granting institutions. Among the participants, gender distribution varies by discipline, with ocean sciences having a large majority of women and earth sciences having a majority of men. Regarding ethnic diversity, the REU Sites reflect the difficulty of attracting diverse students into Geosciences as a discipline; a large majority of participants are Caucasian and Asian students. Furthermore, participants from minority-serving institutions and community colleges constitute a small percentage of those taking part in these research experiences. The enrichment activities are very similar across the REU Sites, and mimic activities common to the scientific community, including intellectual exchange of ideas (lab meetings, seminars, and professional meetings), networking and social activities. The results from this survey will be used to examine strengths in the REU Sites in the Geosciences, opportunities that may be under utilized, and community needs to enhance this NSF wide program.

The Upstream Optioneering project was created by the Nuclear Decommissioning Authority (NDA) Radioactive Waste Management Directorate (RWMD) to support the development and implementation of opportunities to optimise the management of UK higher activity waste, spent fuel and other materials that may be disposed of in a geological disposal facility. The project works in an integrative manner with the NDA, RWMD and waste producers, and was split into three phases: - In Phase 1 waste management opportunities were identified and collated from across the NDA estate. - In Phase 2, opportunities collated during Phase 1, were further consolidated, analysed and prioritisedmore » to develop a three year work programme. Prioritisation ensured that resources were deployed appropriately and opportunities can be realised before the potential benefit diminishes. - Phase 3, which began in April 2012, comprises a three year work programme to address the prioritised opportunities. Work varies from direct implementation of opportunities to scoping studies that may pave the way for more detailed subsequent work by Site Licence Companies. The work programme is flexible and, subject to change control, varies depending on the needs of project sponsors (RWMD, NDA Strategy and NDA Delivery). This paper provides an overview of the Upstream Optioneering project (focusing particularly on Phases 2 and 3), summarises work carried out to date within the three year work programme, and provides some examples of the main findings concerning specific opportunities from Year One of the Phase 3 work programme.

To investigate the prevalence of children with physical disabilities who used a computer-based ATD, and to examine characteristics differences in children and youths who do or do not use computer-based ATDs, as well as, investigate differences that might influence the satisfaction of those two groups of children and youths when computers are being used for in-school and outside school activities. A cross-sectional survey about computer-based activities in and outside school (n = 287) and group comparisons. The prevalence of using computer-based ATDs was about 44 % (n = 127) of the children in this sample. These children were less satisfied with their computer use in education and outside school activities than the children who did not use an ATD. Improved coordination of the usage of computer-based ATDs in school and in the home, including service and support, could increase the opportunities for children with physical disabilities who use computer-based ATDs to perform the computer activities they want, need and are expected to do in school and outside school.

There has been a significant increase in research activity into infectious diseases in Spain in the last few years. The Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) currently has ten study groups, with the cooperation of infectious diseases specialists and microbiologists from different centres, with significant research activity. The program of Redes Temáticas de Investigación Cooperativa en Salud (Special Topics Cooperative Health Research Networks) is an appropriate framework for the strategic coordination of research groups from the Spanish autonomous communities. The Spanish Network for Research in Infectious Diseases (REIPI) and the Network for Research in AIDS (RIS) integrate investigators in Infectious Diseases from multiple groups, which continuously perform important research projects. Research using different experimental models in infectious diseases, in numerous institutions, is an important activity in our country. The analysis of the recent scientific production in Infectious Diseases shows that Spain has a good position in the context of the European Union. The research activity in Infectious Diseases carried out in our country is a great opportunity for the training of specialists in this area of knowledge.

Integration of the brief behavioral activation treatment for depression (BATD) into a college orientation program: depression and alcohol outcomes.

College freshmen face a variety of academic and social challenges as they adjust to college life that can place them at risk for a number of negative outcomes, including depression and alcohol-related problems. Orientation classes that focus on teaching incoming students how to better cope with college-oriented stress may provide an opportunity to prevent the development of these adjustment problems. This article outlines a program based on behavioral activation that can be integrated into college orientation programs to provide a more comprehensive orientation experience. Data are presented from an initial pilot study in which 71 first-semester freshman at the University of Maryland participated in a 15-week, 2 hr per week orientation class (n = 37 in the behavioral activation-enhanced orientation classes and n = 34 in the control orientation as usual classes). Students' depression and alcohol use were evaluated at the beginning, middle, and end of the course. Results indicated a Time × Group interaction such that problem drinking (but not consumption) was significantly reduced across assessments in the behavioral activation classes and largely unchanged in the standard classes. No difference was observed in depression scores; however, fairly low depression scores across the 3 time points may have limited the opportunity to observe any meaningful impact of the orientation classes on depression. The authors conclude with a discussion of the implications of their findings for preventing adjustment problems among incoming college students and future directions.

Physical educators may be the responsible people for implementing comprehensive school physical activity programs (CSPAPs) in schools. However, it is unclear whether physical education teacher education (PETE) programs provide the relevant learning opportunities to preservice teachers for CSPAP implementation. The purpose of this study was to understand preservice teachers' perspectives and experiences of CSPAP preparation in their PETE programs. Fourteen PETE students from 6 different universities participated and shared their experiences in PETE programs. Data were collected through a short survey, 1 formal interview, field images, document gathering, and an additional survey to follow up the interview. Descriptive statistics, constant comparison, and analytic induction techniques were used to analyze the data. Participants' familiarity with CSPAPs was related to positive opinions about the role of physical educators in CSPAPs. Three common themes were revealed: (a) introducing CSPAP via courses, (b) the lack of programwide hands-on experiences for CSPAP, and (c) limited preparation for social skills with stakeholders. Participants' perceptions of the role of physical educators as physical activity leaders had been expanded during their training. The participating PETE programs integrated CSPAP components in the existing courses to introduce CSPAP, while there was a lack of sufficient practical opportunities to learn how to implement (aspects of) a CSPAP. Participants felt they were insufficiently prepared to promote and implement expanded physical activity programming beyond physical education classes in schools. The majority of the PETE preservice teachers wanted more practical CSPAP experiences in their programs.

Using four very different polar outreach case studies, we will discuss scientists' motivations, expectations, and institutional incentives (and dis-incentives) to engage with the public, and argue that improved training, evaluation, and academic value needs to be associated with scientist-led communication efforts - as well as clearer fora for sharing best practice in this field. We will illustrate our argument using examples from an Antarctic festival with public lectures and science cafes, outreach associated with an Antarctic expedition, the global launch of a climate change documentary that had a significant focus on Antarctica, and a series of "Polar Weeks" led by an international community of scientists and educators. While there is an excellent culture of accountability in both formal and informal science communication sectors, the same rigour is not applied to the majority of 'outreach' activities that are initiated by the science research community. Many of these activities are undertaken based on 'what feels right' and opportunism, and are proclaimed to be a success based on little or no formal evaluation. As a result, much of this work goes undocumented, is not evaluated from the perspective of the science community, and is rarely subject to peer-review and its associated benefits, including professional rewards. We therefore recommend new opportunities for publication in this field that would encourage science communication theory and practice to better inform each other, and for scientists to gain professional recognition for their efforts in this arena.

Creating a virtual community of practice to investigate legitimate peripheral participation by African American middle school girls in science activities

NASA Astrophysics Data System (ADS)

Edwards, Leslie D.

How do teenage girls develop an interest in science? What kinds of opportunities can science teachers present to female students that support their engagement with learning science? I studied one aspect of this issue by focusing on ways students could use science to enhance or gain identities that they (probably) already valued. To do that I created technology-rich activities and experiences for an after school class in science and technology for middle school girls who lived in a low socio-economic urban neighborhood. These activities and experiences were designed to create a virtual community of practice whose members used science in diverse ways. Student interest was made evident in their responses to the activities. Four conclusions emerged. (1) Opportunities to learn about the lives and work of admired African American business women interested students in learning by linking it to their middle-class aspirations and their interest in things that money and status can buy. (2) Opportunities to learn about the lives and work of African American women experts in science in a classroom context where students then practiced similar kinds of actual scientific tasks engaged students in relations of legitimate peripheral participation in a virtual and diverse community of practice focused on science which was created in the after-school classes. (3) Opportunities where students used science to show off for family, friends, and supporters of the after-school program, identities they valued, interested them enough that they engaged in long-term science and technology projects that required lots of revisions. (4) In response to the opportunities presented, new and enhanced identities developed around becoming a better student or becoming some kind of scientist.

Current statistics indicate that Latino populations have lower high school and college graduation rates than Anglos or African Americans. If Latinos do not pursue baccalaureate and higher degrees, then this group will be left behind as technological advances increasingly drive our society. The drop out rate affects not only the individuals, families, communities, and society from many different aspects, including financial independence, but also loss of potential contributing members of society in science, engineering, etc. Houston, an urban area, with a Latino population of 39% and Brownsville, a rural area represented by 84% Latinos, are two Texas areas where universities, schools, museums, and NASA are reaching out to increase science skills and graduation rates. Many Houston families have the opportunity to be introduced to different options, but Brownsville families do not have the same opportunities as the area lacks a strong industrial and technological base. We have developed programs to improve the space and Earth science knowledge base by providing summer science enrichment programs for K-12 students, family events, exposing high school students to college opportunities, and training high school and college students to serve as mentors to their peers. The peer mentors lead many of the outreach venues, interacting with the public with demonstrations and interactive science activities. In addition, we have developed a series of teacher workshops and modules on integrated science and mathematics. The teacher workshops are designed to provide the teachers with a wealth of integrated examples for classroom use.

There are no longer doubts about the existence of gender's differences in cognition, only their origin is still controversial. The literature provides evidence of differences in cognitive performance and brain activation patterns and links these differences in men and women with biological, social and psychological measures. To date, the favored hypothesis explaining these differences is the cognitive style hypothesis according to which women and men would favor different strategies while resolving some tasks. Some of these tasks are autobiographical memory tasks, which are also the most sensitive to the effects of age but very few studies had explored the impact of aging on the differences in cognition between men and women. We discuss the importance of such studies about the gender's differences in aging. A better understanding of gender differences in cognition in pathological aging as in health would provide the opportunity to offer a more personalized care.

To describe the experiences and perspectives of children and adolescents on dialysis. A systematic review of qualitative studies was conducted that explored the experiences of children on dialysis. Electronic databases and reference lists of relevant articles were searched to October Week 2, 2010. A total of 17 studies, which reported the experiences of 143 children receiving dialysis, were included. Five major themes were identified: loss of control (high reliance on carers, parental overprotectiveness, unrelenting dependence on a machine, impaired body integrity), restricted lifestyle (limited socialisation opportunities, academic struggle), coping strategies (hope for kidney transplant and medical advances, social support, positive determination and self-awareness, engaging in activities, denial), managing treatment (ownership, proactive involvement, adherence to fluid and diet restrictions) and feeling different (abnormal physical appearance, injustice, being a burden). Children undergoing dialysis experience impaired growth, invasive procedures, school and social constraints. They often have poor self-esteem and a pervasive sense of losing their identity, body integrity, control, independence and opportunity. Interventions are needed to equip children with the capacity to manage their health, participate in community, engage in 'permissible' recreational activities, progress in their studies, and remain vigilant in dialysis and treatment responsibilities, for improved health and treatment outcomes.

The author sketches some pressing questions in several active areas of particle physics and outline the challenges they present for the design and operation of detectors. His assignment at the 1999 ICFA Instrumentation School is to survey some current developments in particle physics, and to describe the kinds of experiments they would like to do in the near future and illustrate the demands their desires place on detectors and data analysis. Like any active science, particle physics is in a state of continual renewal. Many of the subjects that seem most fascinating and most promising today simply did not existmore » as recently as twenty-five years ago. Other topics that have preoccupied physicists for many years have been reshaped by recent discoveries and insights, and transformed by new techniques in accelerator science and detector technology. To provide some context for the courses and laboratories at this school, he has chosen three topics that are of high scientific interest, and that place very different demands on instrumental techniques. He hopes that you will begin to see the breadth of opportunities in particle physics, and that you will also look beyond the domain of particle physics for opportunities to apply the lessons you learn here in Istanbul.« less

Background Physical activity is important for weight control and good health; however, activity levels decline in the adolescent years, particularly in girls. Design Group randomized controlled trial Setting/participants Middle school girls with English-speaking skills and no conditions to prevent participation in physical activity in 36 schools in six geographically diverse areas of the United States. Random, cross-sectional samples were drawn within schools: 6th graders in 2003 (n=1721) and 8th graders in 2005 (n=3504) and 2006 (n=3502). Intervention A 2-year study-directed intervention (fall 2003 to spring 2005) targeted schools, community agencies, and girls to increase opportunities, support, and incentives for increased physical activity. Components included programs linking schools and community agencies, physical education, health education, and social marketing. A third-year intervention used school and community personnel to direct intervention activities. Main outcome measures The primary outcome, daily MET-weighted minutes of moderate-to-vigorous physical activity (MET-weighted MVPA), was assessed using accelerometry. Percent body fat was assessed using anthropometry. Results After the staff-directed intervention (pre-stated primary outcome), there were no differences (mean= −0.4, 95% CI= CI= −8.2 to 7.4) in adjusted MET-weighted MVPA between 8th-grade girls in schools assigned to intervention or control. Following the Program Champion–directed intervention, girls in intervention schools were more physically active than girls in control schools (mean difference 10.9 MET-weighted minutes of MVPA, 95% CI=0.52–21.2). This difference is about 1.6 minutes of daily MVPA or 80 kcal per week. There were no differences in fitness or percent body fat at either 8th-grade timepoint. Conclusion A school-based, community-linked intervention modestly improved physical activity in girls. PMID:18312804

Metal–organic framework supported cobalt catalysts for the oxidative dehydrogenation of propane at low temperature

DOE PAGES

Li, Zhanyong; Peters, Aaron W.; Bernales, Varinia; ...

2016-11-30

Here, Zr-based metal–organic frameworks (MOFs) have been shown to be excellent catalyst supports in heterogeneous catalysis due to their exceptional stability. Additionally, their crystalline nature affords the opportunity for molecular level characterization of both the support and the catalytically active site, facilitating mechanistic investigations of the catalytic process. We describe herein the installation of Co(II) ions to the Zr 6 nodes of the mesoporous MOF, NU-1000, via two distinct routes, namely, solvothermal deposition in a MOF (SIM) and atomic layer deposition in a MOF (AIM), denoted as Co-SIM+NU-1000 and Co-AIM+NU-1000, respectively. The location of the deposited Co species in themore » two materials is determined via difference envelope density (DED) analysis. Upon activation in a flow of O 2 at 230 °C, both materials catalyze the oxidative dehydrogenation (ODH) of propane to propene under mild conditions. Catalytic activity as well as propene selectivity of these two catalysts, however, is different under the same experimental conditions due to differences in the Co species generated in these two materials upon activation as observed by in situ X-ray absorption spectroscopy. A potential reaction mechanism for the propane ODH process catalyzed by Co-SIM+NU-1000 is proposed, yielding a low activation energy barrier which is in accord with the observed catalytic activity at low temperature.« less

Understanding the physical activity promotion behaviours of podiatrists: a qualitative study.

Crisford, Paul; Winzenberg, Tania; Venn, Alison; Cleland, Verity

2013-09-09

Health professionals are encouraged to play a part in reducing the health risks of physical inactivity. Little is known of the physical activity promotion practice behaviours of podiatrists. We performed 20 semi-structured interviews with purposefully selected podiatrists to explore their physical activity promotion attitudes, beliefs, knowledge and practice. Transcribed interviews were coded using an iterative thematic approach to identify major themes and salient beliefs. Overall, the participants had a positive attitude to physical activity promotion, considering it a normal part of their role. They saw their role as giving information, encouraging activity and making recommendations, however in practice they were less inclined to follow up on recommendations, monitor activity levels or document the process. Their approach was generally opportunistic, informal and unstructured and the content of assessment and promotion dependent upon the presenting patient's condition. Advice tended to be tailored to the patient's capabilities and interests. They considered there are opportunities to promote physical activity during regular consultations, however, were more likely to do so in patients with chronic diseases such as diabetes. Main barriers to physical activity promotion included unreceptive and unmotivated patients as well as a lack of time, skills and resources. Physical activity promotion appears feasible in podiatry practice in terms of opportunity and acceptability to practitioners, but there is scope for improvement. Strategies to improve promotion need to consider the major issues, barriers and opportunities as well as provide a more structured approach to physical activity promotion by podiatrists.

The Active Living Logan Square target audience is the community of the southwest corner of Logan Square, an urban Chicago community of 84,466 residents, mostly Latinos. Through the Active Living by Design (ALbD) initiative, the Logan Square Neighborhood Association leveraged its 48 years of existence in the neighborhood to create opportunities and build partnerships. Activities addressed three primary goals: (1) enhance school environments and practices to support physical activity before, during, and after the school day; (2) encourage individuals and families to enjoy outdoor activities in their own communities; and (3) create safe, inviting places for activity that connect to surrounding communities. The partnership's participatory approach involved a variety of community stakeholders in developing and implementing affordable, accessible, culturally acceptable, and sustainable physical activities for children and their families. The partnership successfully piloted Open Streets (temporary street closures) and advocated for development of the Bloomingdale Trail, an elevated rails-to-trails project. In schools, the partnership changed the culture at McAuliffe Elementary to support healthy behaviors through new policies, physical projects, and programs. Vital components of the project's success included a full-time coordinator with strong community ties; time to build healthy relationships within the partnership and community; the use of culturally relevant strategies; and flexibility to welcome complementary opportunities. The partnership intentionally did not produce a single community-recognized campaign; instead, it chose to use limited resources to promote tangible programs and projects that led to sustainable and replicable changes that promote physical activity.

Can pharmaceutical co-crystals provide an opportunity to modify the biological properties of drugs?

PubMed

Dalpiaz, Alessandro; Pavan, Barbara; Ferretti, Valeria

2017-08-01

Poorly soluble and/or permeable molecules jeopardize the discovery and development of innovative medicines. Pharmaceutical co-crystals, formed by an active pharmaceutical substance (API) and a co-crystal former, can show enhanced dissolution and permeation values compared with those of the parent crystalline pure phases. It is currently assumed that co-crystallization with pharmaceutical excipients does not affect the pharmacological activity of an API or, indeed, might even improve physical properties such as solubility and permeability. However, as we highlight here, the biological behavior of co-crystals can differ drastically with respect to that of their parent physical mixtures. Copyright © 2017 Elsevier Ltd.

Throughout the US, high-visibility drug markets are concentrated in neighborhoods with few economic opportunities, while drug buyers/users are widely dispersed. A study of Pittsburgh Syringe Exchange participants provides data on travel between and network linkages across neighborhoods with different levels of drug activity. There are distinct racial patterns to syringe distribution activity within networks and across neighborhoods. Pittsburgh’s history suggests these patterns emerge from historical patterns of social and economic development. Study data demonstrate the ability of IDUs to form long term social ties across racial and geographic boundaries and use them to reduce the risk of HIV transmission. PMID:19578475

The discovery and understanding of nanoscale phenomena and the assembly of nanostructures into different devices are among the most promising fields of material science research. In this scenario, carbon nanostructures have a special role since, in having only one chemical element, they allow physical properties to be calculated with high precision for comparison with experiment. Carbon nanostructures, and carbon nanotubes (CNTs) in particular, have such remarkable electronic and structural properties that they are used as active building blocks for a large variety of nanoscale devices. We review here the latest advances in research involving carbon nanotubes as active components in electronic and optoelectronic nano-devices. Opportunities for future research are also identified.

Venezuelan Biomedical journals have been confronting, for several years, a gradual decline both, from the standpoint of their management and in the quality of their editorial content. At its highest level, Venezuela had about sixty different titles. But irregular financial support, as well as the lack of a clear official policy, regarding these scientific activities, were some of the reasons that have contributed to this decline. Several recent Venezuelan and international documents provide an important legal support for the design of new official policies and government responsibilities. There is now a valid opportunity to profit from new tools to evaluate and improve the quality of our scientific and editorial activities.

Adventures in supercomputing: Scientific exploration in an era of change

Students deserve the opportunity to explore the world of science surrounding them. Therefore it is important that scientific exploration and investigation be a part of each student`s educational career. The Department of Energy`s Adventures in Superconducting (AiS) takes students beyond mere scientific literacy to a rich embodiment of scientific exploration. AiS provides today`s science and math students with a greater opportunity to investigate science problems, propose solutions, explore different methods of solving the problem, organize their work into a technical paper, and present their results. Students learn at different rates in different ways. Science classes with students having varying learningmore » styles and levels of achievement have always been a challenge for teachers. The AiS {open_quotes}hands-on, minds-on{close_quotes} project-based method of teaching science meets the challenge of this diversity heads on! AiS uses the development of student chosen projects as the means of achieving a lifelong enthusiasm for scientific proficiency. One goal of AiS is to emulate the research that takes place in the everyday environment of scientists. Students work in teams and often collaborate with students nationwide. With the help of mentors from the academic and scientific community, students pose a problem in science, investigate possible solutions, design a mathematical and computational model for the problem, exercise the model to achieve results, and evaluate the implications of the results. The students then have the opportunity to present the project to their peers, teachers, and scientists. Using this inquiry-based technique, students learn more than science skills, they learn to reason and think -- going well beyond the National Science Education Standard. The teacher becomes a resource person actively working together with the students in their quest for scientific knowledge.« less

Medical students' opportunities to participate and learn from activities at an internal medicine ward: an ethnographic study.

Hägg-Martinell, A; Hult, H; Henriksson, P; Kiessling, A

2017-02-14

To optimise medical students' early clerkship is a complex task since it is conducted in a context primarily organised to take care of patients. Previous studies have explored medical students' perceptions of facilitation and hindrance of learning. However, the opportunities for medical student to learn within the culture of acute medicine care have not been fully investigated. This study aimed to explore how medical students approach, interact and socialise in an acute internal medicine ward context, and how spaces for learning are created and used in such a culture. Ethnographic observations were performed of medical students' interactions and learning during early clerkship at an acute internal medicine care ward. Field notes were taken, transcribed and analysed qualitatively. Data analysis was guided by Wenger's theory of communities of practice. 21 medical students and 30 supervisors participated. Two themes were identified: Nervousness and curiosity- students acted nervously and stressed, especially when they could not answer questions. Over time curiosity could evolve. Unexplored opportunities to support students in developing competence to judge and approach more complex patient-related problems were identified. Invited and involved -students were exposed to a huge variation of opportunities to learn, and to interact and to be involved. Short placements seemed to disrupt the learning process. If and how students became involved also depended on supervisors' activities and students' initiatives. This study shed light on how an acute internal medicine ward culture can facilitate medical students' possibilities to participate and learn. Medical students' learning situations were characterised by questions and answers rather than challenging dialogues related to the complexity of presented patient cases. Further, students experienced continuous transfers between learning situations where the potential to be involved differed in a wide variety of ways. Published by the BMJ Publishing Group Limited.

The increasing numbers of colonias along the U.S.-Mexico border are characterized by disproportionately poor families of Mexican-origin, limited access to resources and health services, and heightened risk for obesity and diabetes. Despite consistent evidence supporting physical activity (PA) in prevention of chronic diseases, many individuals of Mexican-origin, including children, fail to meet PA recommendations. Environmental influences on PA, founded in ecological and social cognitive perspectives, have not been examined among children living in colonias. The purpose of this study was to identify and better understand (1) household and neighborhood environmental PA resources/supports, (2) perceived barriers to engaging in PA, and (3) PA offerings, locations, and transportation characteristics for Mexican-origin children living in colonias. Data for this study were collected by promotora-researchers (indigenous community health workers trained in research methods) using face-to-face interviews conducted in Spanish. The sample consists of 94 mother-child dyads from Texas border colonias in Hidalgo County. Interviews included questionnaire items addressing PA barriers, household and neighborhood environmental support assessments conducted with each dyad, and open-ended questions that were coded to identify availability and locations of PA opportunities and transportation options. Descriptive statistics were calculated and differences between genders, birth countries, and BMI categories of children were determined using chi-square tests. All children were of Mexican-origin. The most frequently reported barriers were unleashed dogs in the street, heat, bad weather, traffic, no streetlights, and no place like a park to exercise. Prominent locations for current PA included schools, home, and parks. Common PA options for children were exercise equipment, running, playing, and sports. Environmental assessments identified exercise equipment (bicycles/tricycles, balls, etc.…), paved/good streets, yard/patio space, and social norms as the most frequent household or neighborhood resources within these colonias. Differences in PA barriers, options, and environmental resources for genders, birth countries, and BMI categories were detected. This study suggests that PA environmental resources, barriers, and opportunities for colonias children are similar to previous studies and distinctively unique. As expected, built resources in these communities are limited and barriers exist; however, knowledge of PA opportunities and available PA resources within colonias households and neighborhoods offers insight to help guide future research, policy, and PA initiatives.

Exercise, character strengths, well-being, and learning climate in the prediction of performance over a 6-month period at a call center.

Moradi, Saleh; Nima, Ali A; Rapp Ricciardi, Max; Archer, Trevor; Garcia, Danilo

2014-01-01

Performance monitoring might have an adverse influence on call center agents' well-being. We investigate how performance, over a 6-month period, is related to agents' perceptions of their learning climate, character strengths, well-being (subjective and psychological), and physical activity. Agents (N = 135) self-reported perception of the learning climate (Learning Climate Questionnaire), character strengths (Values In Action Inventory Short Version), well-being (Positive Affect, Negative Affect Schedule, Satisfaction With Life Scale, Psychological Well-Being Scales Short Version), and how often/intensively they engaged in physical activity. Performance, "time on the phone," was monitored for 6 consecutive months by the same system handling the calls. Performance was positively related to having opportunities to develop, the character strengths clusters of Wisdom and Knowledge (e.g., curiosity for learning, perspective) and Temperance (e.g., having self-control, being prudent, humble, and modest), and exercise frequency. Performance was negatively related to the sense of autonomy and responsibility, contentedness, the character strengths clusters of Humanity and Love (e.g., helping others, cooperation) and Justice (e.g., affiliation, fairness, leadership), positive affect, life satisfaction and exercise Intensity. Call centers may need to create opportunities to develop to increase agents' performance and focus on individual differences in the recruitment and selection of agents to prevent future shortcomings or worker dissatisfaction. Nevertheless, performance measurement in call centers may need to include other aspects that are more attuned with different character strengths. After all, allowing individuals to put their strengths at work should empower the individual and at the end the organization itself. Finally, physical activity enhancement programs might offer considerable positive work outcomes.

The GK-12 OCEANS program is an initiative of the National Science Foundation (NSF). This program provides marine science graduate students within the College of Marine Science, USF, weekly interactions with K-12 teachers and students in Pinellas County schools with the overall purpose of enhancing the quality and effectiveness of science teaching. The GK-12 OCEANS program provides hands-on and minds-on ocean science learning inquiries. Campbell Park Elementary is a Marine Science attractor school designed to provide a child-centered approach to learning that integrates marine science activities into the daily curriculum while meeting the required state education standards. In 2003-04 a GK-12 Fellow helped third and fourth grade teachers design new teaching curricula that integrated ocean sciences. The current 2004-04 Fellow and teachers are implementing the new curriculum, assessing feasibility and impact on students' learning. One characteristic of the new curriculum includes several field trips to local natural settings during which students have the opportunity to collect data the way scientists do, and use real scientific instruments and approaches. The information collected is then used in different activities within the classroom. These activities encourage the students to use inquiry as the basis of their learning experience, in which the application of scientific thinking and methods are keys. This process also requires the students to apply skills from other disciplines such as writing, reading, and math. Towards the end of the school year the students have the opportunity to highlight their accomplishments through two projects, 1) a hall display of different ocean zones, which includes habitat characteristics and species adaptations, and 2) a marine science experiment presented at the school science fair. The results and accomplishments from the implementation of these new curricula will be presented at the conference.

Exercise, character strengths, well-being, and learning climate in the prediction of performance over a 6-month period at a call center

2014-01-01

Background: Performance monitoring might have an adverse influence on call center agents' well-being. We investigate how performance, over a 6-month period, is related to agents' perceptions of their learning climate, character strengths, well-being (subjective and psychological), and physical activity. Method: Agents (N = 135) self-reported perception of the learning climate (Learning Climate Questionnaire), character strengths (Values In Action Inventory Short Version), well-being (Positive Affect, Negative Affect Schedule, Satisfaction With Life Scale, Psychological Well-Being Scales Short Version), and how often/intensively they engaged in physical activity. Performance, “time on the phone,” was monitored for 6 consecutive months by the same system handling the calls. Results: Performance was positively related to having opportunities to develop, the character strengths clusters of Wisdom and Knowledge (e.g., curiosity for learning, perspective) and Temperance (e.g., having self-control, being prudent, humble, and modest), and exercise frequency. Performance was negatively related to the sense of autonomy and responsibility, contentedness, the character strengths clusters of Humanity and Love (e.g., helping others, cooperation) and Justice (e.g., affiliation, fairness, leadership), positive affect, life satisfaction and exercise Intensity. Conclusion: Call centers may need to create opportunities to develop to increase agents' performance and focus on individual differences in the recruitment and selection of agents to prevent future shortcomings or worker dissatisfaction. Nevertheless, performance measurement in call centers may need to include other aspects that are more attuned with different character strengths. After all, allowing individuals to put their strengths at work should empower the individual and at the end the organization itself. Finally, physical activity enhancement programs might offer considerable positive work outcomes. PMID:25002853

Social media and suicide prevention: findings from a stakeholder survey.

Suicide is a leading cause of death, particularly among young adults. The rapid growth of social media and its heavy use by young adults presents new challenges and opportunities for suicide prevention. Social media sites are commonly used for communicating about suicide-related behavior with others, which raises the possibility of using social media to help prevent suicide. However, the use of social media varies widely between different suicide prevention advocates. The role this type of intervention should play in a community's overall suicide prevention strategy remains a matter of debate. Explore the ways in which stakeholders use social media for suicide prevention and assess their views about the potential utility of social media as a suicide prevention tool. A 12-week stakeholder consultation that involved the online administration and completion of surveys by 10 individuals who conduct research about suicide and social media, 13 organizations that use social media for suicide prevention purposes, and 64 users of social media. Social media was seen as a useful means of delivering a range of suicide prevention activities. Respondents reported that the key benefits of social media were the opportunity to obtain emotional support from others, to express one's feelings, to talk to others with similar problems, and to provide help to others. The social media site believed to hold most potential for delivering suicide prevention activities was Facebook. There were concerns about potential risks of social media, but respondents felt the potential benefits outweighed the risks. Social media was recognized by different types of stakeholders as holding potential for delivering suicide prevention activities. More research is required to establish the efficacy and safety of potential social media-based interventions and ethical standards and protocols to ensure that such interventions are delivered safely need to be developed and implemented.

A critical comparison of systematic calibration protocols for activated sludge models: a SWOT analysis.

2005-07-01

Modelling activated sludge systems has gained an increasing momentum after the introduction of activated sludge models (ASMs) in 1987. Application of dynamic models for full-scale systems requires essentially a calibration of the chosen ASM to the case under study. Numerous full-scale model applications have been performed so far which were mostly based on ad hoc approaches and expert knowledge. Further, each modelling study has followed a different calibration approach: e.g. different influent wastewater characterization methods, different kinetic parameter estimation methods, different selection of parameters to be calibrated, different priorities within the calibration steps, etc. In short, there was no standard approach in performing the calibration study, which makes it difficult, if not impossible, to (1) compare different calibrations of ASMs with each other and (2) perform internal quality checks for each calibration study. To address these concerns, systematic calibration protocols have recently been proposed to bring guidance to the modeling of activated sludge systems and in particular to the calibration of full-scale models. In this contribution four existing calibration approaches (BIOMATH, HSG, STOWA and WERF) will be critically discussed using a SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis. It will also be assessed in what way these approaches can be further developed in view of further improving the quality of ASM calibration. In this respect, the potential of automating some steps of the calibration procedure by use of mathematical algorithms is highlighted.

McDowell Observatory located in Lyndhurst, NJ. Perched atop a closed and reclaimed municipal solid waste landfill, our new LEED - certified building (certification pending) and William D. McDowell observatory will assist in bringing the goals of IYA 2009 to the approximately 25,000 students and 15,000 adults that visit our site from the NY/NJ region each year. Diversifying our traditional environmental science offerings, we have incorporated astronomy into our repertoire with "The Sun Through Time” module, which includes storytelling, cultural astronomy, telescope anatomy, and other activities that are based on the electromagnetic spectrum and our current knowledge of the sun. These lessons have also been modified to bring astronomy to underserved communities, specifically those individuals that have dexterity or cognitive ability differences. The program is conducted in a classroom setting and is designed to meet New Jersey Core Curriculum Content Standards. With the installation of our new 20” telescope, students and amateur astronomers will be given the opportunity to perform rudimentary research. In addition, a program is in development that will allow individuals to measure local sky brightness and understand the effects of light pollution on astronomical viewing. Teaching astronomy in an urban setting presents many challenges. All individuals, regardless of ability level or location, should be given the opportunity to be exposed to the wonders of the universe and the MEC/CESE has been successful in providing those opportunities.

Diurnal time-activity budgets of redheads (Aythya americana) wintering in seagrass beds and coastal ponds in Louisiana and Texas

USGS Publications Warehouse

Michot, T.C.; Woodin, M.C.; Adair, S.E.; Moser, E.B.

2006-01-01

Diurnal time-activity budgets were determined for wintering redheads (Aythya americana) from estuarine seagrass beds in Louisiana (Chandeleur Sound) and Texas (Laguna Madre) and from ponds adjacent to the Laguna Madre. Activities differed (p<0.0001) by location, month, and diurnal time period. Resting and feeding were the most frequent activities of redheads at the two estuarine sites, whereas drinking was almost nonexistent. Birds on ponds in Texas engaged most frequently in resting and drinking, but feeding was very infrequent. Redheads from the Louisiana estuarine site rested less than birds in Texas at either the Laguna Madre or freshwater ponds. Redheads in Louisiana fed more than birds in Texas; this was partially because of weather differences (colder temperatures in Louisiana), but the location effect was still significant even when we adjusted the model for weather effects. Redheads in Louisiana showed increased resting and decreased feeding as winter progressed, but redheads in Texas did not exhibit a seasonal pattern in either resting or feeding. In Louisiana, birds maintained a high level of feeding activity during the early morning throughout the winter, whereas afternoon feeding tapered off in mid- to late-winter. Texas birds showed a shift from morning feeding in early winter to afternoon feeding in late winter. Males and females at both Chandeleur Sound and Laguna Madre showed differences in their activities, but because the absolute difference seldom exceeded 2%, biological significance is questionable. Diurnal time-activity budgets of redheads on the wintering grounds are influenced by water salinities and the use of dietary fresh water, as well as by weather conditions, tides, and perhaps vegetation differences between sites. The opportunity to osmoregulate via dietary freshwater, vs. via nasal salt glands, may have a significant effect on behavioral allocations. ?? Springer 2006.

Carbon dioxide conversion over carbon-based nanocatalysts.

Khavarian, Mehrnoush; Chai, Siang-Piao; Mohamed, Abdul Rahman

2013-07-01

The utilization of carbon dioxide for the production of valuable chemicals via catalysts is one of the efficient ways to mitigate the greenhouse gases in the atmosphere. It is known that the carbon dioxide conversion and product yields are still low even if the reaction is operated at high pressure and temperature. The carbon dioxide utilization and conversion provides many challenges in exploring new concepts and opportunities for development of unique catalysts for the purpose of activating the carbon dioxide molecules. In this paper, the role of carbon-based nanocatalysts in the hydrogenation of carbon dioxide and direct synthesis of dimethyl carbonate from carbon dioxide and methanol are reviewed. The current catalytic results obtained with different carbon-based nanocatalysts systems are presented and how these materials contribute to the carbon dioxide conversion is explained. In addition, different strategies and preparation methods of nanometallic catalysts on various carbon supports are described to optimize the dispersion of metal nanoparticles and catalytic activity.

Disasters and development in agricultural input markets: bean seed markets in Honduras after Hurricane Mitch.

PubMed

Mainville, Denise Y

2003-06-01

The bulk of developing countries' populations and poor depend on agriculture for food and income. While rural economies and people are generally the most severely affected by natural disasters, little is known about how disasters and subsequent relief activities affect agricultural markets with differing levels of development. The article addresses this gap, drawing evidence from bean seed markets in Honduras after Hurricane Mitch. Case studies are used to address hypotheses about a disaster's effects on supply and demand in seed markets, farmers' responses and the performance of relief interventions in markets showing differing levels of development. The results show the importance of tailoring relief interventions to the markets that they will affect and to the specific effects of a disaster; the potential to use local and emerging seed distribution channels in a relief intervention; and opportunities for relief activities to strengthen community seed systems.

Neighborhood Environments and Physical Activity: A Longitudinal Study of Adolescents in a Natural Experiment.

PubMed

Nicosia, Nancy; Datar, Ashlesha

2018-05-01

Experimental and quasi-experimental evidence on the relationship between adolescents' physical activity and their physical activity environments is scarce. This study provides natural experimental evidence using within-person longitudinal variation in physical activity environments resulting from the compulsory re-assignment of military families to new installations, termed permanent changes of station. Adolescents in Army families (N=749) reported usual weekly minutes of moderate and vigorous physical activity in 2013-2015. Objective measures of the physical activity environment, including the number of fitness and recreation facilities within 2 miles, were constructed for adolescents' neighborhoods using GIS methods. In 2017, individual-level fixed-effects models with and without a comparison group estimated the relationship between usual weekly minutes of physical activity and physical activity environments among permanent changes of station movers using within-person variation. Increases in opportunities for physical activity were significantly and positively associated with increases in total (p<0.05) and vigorous physical activity (p<0.05) among adolescents who experienced permanent changes of station moves. The relationships were statistically significant for permanent changes of station movers living off-installation (p<0.05) and hence subject to greater variation in physical activity environments and those with more time to adjust to their new environments (p<0.05). Significant findings persisted when broader measures of physical activity environments were utilized. The decline in physical activity and alarming obesity levels during adolescence suggest that this age may represent an important opportunity to address the obesity epidemic. This study provides evidence that increasing opportunities for physical activity may be an important pathway to improving their levels of physical activity and, consequently, obesity.

Getting going and letting go: Religiosity fosters opportunity-congruent coping with work-related uncertainties.

PubMed

Lechner, Clemens M; Silbereisen, Rainer K; Tomasik, Martin J; Wasilewski, Jacek

2015-06-01

This study investigated how religiosity relates to goal engagement (i.e., investing time and effort; overcoming obstacles) and goal disengagement (i.e., protecting self-esteem and motivational resources against failure experiences; distancing from unattainable goals) in coping with perceived work-related uncertainties (e.g., growing risk of job loss) that arise from current social change. We hypothesised that religiosity not only expands individuals' capacities for both engagement and disengagement but also fosters an opportunity-congruent pattern of engagement and disengagement, promoting engagement especially under favourable opportunities for goal-striving in the social ecology and facilitating disengagement especially under unfavourable opportunities. Multilevel analyses in a sample of N = 2089 Polish adults aged 20-46 years partly supported these predictions. Religiosity was associated with higher goal engagement, especially under favourable economic opportunities for goal-striving in the social ecology (as measured by the regional net migration rate). For disengagement, the results were more mixed; religiosity was related to higher self-protection independently of the economic opportunity structure and predicted higher goal-distancing only under the most unfavourable opportunities. These results suggest that religiosity can promote different coping strategies under different conditions, fostering a pattern of opportunity-congruent engagement and, to some extent, disengagement that is likely to be adaptive. © 2014 International Union of Psychological Science.

Strengths, weaknesses, opportunities, and threats analysis of integrating the World Health Organization patient safety curriculum into undergraduate medical education in Pakistan: a qualitative case study.

PubMed

Misbah, Samreen; Mahboob, Usman

2017-01-01

The purpose of this study was to conduct a strengths, weaknesses, opportunities, and threats (SWOT) analysis of integrating the World Health Organization (WHO) patient safety curriculum into undergraduate medical education in Pakistan. A qualitative interpretive case study was conducted at Riphah International University, Islamabad, from October 2016 to June 2017. The study included 9 faculty members and 1 expert on patient safety. The interviews were audiotaped, and a thematic analysis of the transcripts was performed using NVivo software. Four themes were derived based on the need analysis model. The sub-themes derived from the collected data were arranged under the themes of strengths, weaknesses, opportunities, and threats, in accordance with the principles of SWOT analysis. The strengths identified were the need for a formal patient safety curriculum and its early integration into the undergraduate program. The weaknesses were faculty awareness and participation in development programs. The opportunities were an ongoing effort to develop an appropriate curriculum, to improve the current culture of healthcare, and to use the WHO curricular resource guide. The threats were attitudes towards patient safety in Pakistani culture, resistance to implementation from different levels, and the role of regulatory authorities. The theme of patient safety needs to be incorporated early into the formal medical education curriculum, with the main goals of striving to do no harm and seeing mistakes as opportunities to learn. Faculty development activities need to be organized, and faculty members should to be encouraged to participate in them. The lack of a patient safety culture was identified as the primary reason for resistance to this initiative at many levels. The WHO curriculum, amended according to local institutional culture, can be implemented appropriately with support from the corresponding regulatory bodies.

Patient-centred care in established rheumatoid arthritis.

PubMed

Voshaar, M J H; Nota, I; van de Laar, M A F J; van den Bemt, B J F

2015-01-01

Review of the evidence on patient-centred care (PCC) in rheumatoid arthritis (RA) shows that involving the patient as an individual - with unique needs, concerns and preferences - has a relevant impact on treatment outcomes (safety, effectiveness and costs). This approach empowers patients to take personal responsibility for their treatment. Because clinicians are only able to interact personally with their patients just a few hours per year, patients with a chronic condition such as RA should be actively involved in the management of their disease. To stimulate this active role, five different PCC activities can be distinguished: (1) patient education, (2) patient involvement/shared decision-making, (3) patient empowerment/self-management, (4) involvement of family and friends and (5) physical and emotional support. This article reviews the existing knowledge on these five PCC activities in the context of established RA management, especially focused on opportunities to increase medication adherence in established RA.

Multi-level Discourse Analysis in a Physics Teaching Methods Course from the Psychological Perspective of Activity Theory

NASA Astrophysics Data System (ADS)

Vieira, Rodrigo Drumond; Kelly, Gregory J.

2014-11-01

In this paper, we present and apply a multi-level method for discourse analysis in science classrooms. This method is based on the structure of human activity (activity, actions, and operations) and it was applied to study a pre-service physics teacher methods course. We argue that such an approach, based on a cultural psychological perspective, affords opportunities for analysts to perform a theoretically based detailed analysis of discourse events. Along with the presentation of analysis, we show and discuss how the articulation of different levels offers interpretative criteria for analyzing instructional conversations. We synthesize the results into a model for a teacher's practice and discuss the implications and possibilities of this approach for the field of discourse analysis in science classrooms. Finally, we reflect on how the development of teachers' understanding of their activity structures can contribute to forms of progressive discourse of science education.

Need for cognition can magnify or attenuate priming effects in social judgment.

PubMed

Petty, Richard E; DeMarree, Kenneth G; Briñol, Pablo; Horcajo, Javier; Strathman, Alan J

2008-07-01

This article hypothesizes that the individual-difference variable, need for cognition (NFC), can have opposite implications for priming effects, depending on prime blatancy. Subtle primes are argued to be more effective for high- versus low-NFC individuals. This is because for high-NFC individuals, (a) constructs are generally easier to activate, (b) their higher amount of thought offers more opportunity for an activated construct to bias judgment, and (c) their thoughtfully formed judgments are more likely to affect behavior. However, because high-NFC individuals are adept at identifying and correcting for bias, with blatant primes the activated construct should be less likely to exert its default influence. Furthermore, with blatant primes, low-NFC individuals may achieve sufficient activation for primes to affect judgment. Across three studies, it is shown that as NFC increases, the magnitude of priming effects increases with a subtle prime but decreases with a blatant prime.

Patient activation and use of an electronic patient portal.

PubMed

Ancker, Jessica S; Osorio, Snezana N; Cheriff, Adam; Cole, Curtis L; Silver, Michael; Kaushal, Rainu

2015-01-01

Electronic patient portals give patients access to personal medical data, potentially creating opportunities to improve knowledge, self-efficacy, and engagement in healthcare. The combination of knowledge, self-efficacy, and engagement has been termed activation. Our objective was to assess the relationship between patient activation and outpatient use of a patient portal. Survey. A telephone survey was conducted with 180 patients who had been given access to a portal, 113 of whom used it and 67 of whom did not. The validated patient activation measure (PAM) was administered along with questions about demographics and behaviors. Portal users were no different from nonusers in patient activation. Portal users did have higher education level and more frequent Internet use, and were more likely to have precisely 2 prescription medications than to have more or fewer. Patients who chose to use an electronic patient portal were not more highly activated than nonusers, although they were more educated and more likely to be Internet users.

Higher cost of single incision laparoscopic cholecystectomy due to longer operating time. A study of opportunity cost based on meta-analysis

PubMed Central

GIRABENT-FARRÉS, M.

2018-01-01

Background We aimed to calculate the opportunity cost of the operating time to demonstrate that single incision laparoscopic cholecystectomy (SILC) is more expensive than classic laparoscopic cholecystectomy (CLC). Methods We identified studies comparing use of both techniques during the period 2008–2016, and to calculate the opportunity cost, we performed another search in the same period of time with an economic evaluation of classic laparoscopy. We performed a meta-analysis of the items selected in the first review considering the cost of surgery and surgical time, and we analyzed their differences. We subsequently calculated the opportunity cost of these time differences based on the design of a cost/time variable using the data from the second literature review. Results Twenty-seven articles were selected from the first review: 26 for operating time (3.138 patients) and 3 for the cost of surgery (831 patients), and 3 articles from the second review. Both techniques have similar operating costs. Single incision laparoscopy surgery takes longer (16.90min) to perform (p <0.00001) and this difference represents an opportunity cost of 755.97 € (cost/time unit factor of 44.73 €/min). Conclusions SILC costs the same as CLC, but the surgery takes longer to perform, and this difference involves an opportunity cost that increases the total cost of SILC. The value of the opportunity cost of the operating time can vary the total cost of a surgical technique and it should be included in the economic evaluation to support the decision to adopt a new surgical technique.

Chimpanzees and bonobos differ in intrinsic motivation for tool use.

PubMed

Koops, Kathelijne; Furuichi, Takeshi; Hashimoto, Chie

2015-06-16

Tool use in nonhuman apes can help identify the conditions that drove the extraordinary expansion of hominin technology. Chimpanzees and bonobos are our closest living relatives. Whereas chimpanzees are renowned for their tool use, bonobos use few tools and none in foraging. We investigated whether extrinsic (ecological and social opportunities) or intrinsic (predispositions) differences explain this contrast by comparing chimpanzees at Kalinzu (Uganda) and bonobos at Wamba (DRC). We assessed ecological opportunities based on availability of resources requiring tool use. We examined potential opportunities for social learning in immature apes. Lastly, we investigated predispositions by measuring object manipulation and object play. Extrinsic opportunities did not explain the tool use difference, whereas intrinsic predispositions did. Chimpanzees manipulated and played more with objects than bonobos, despite similar levels of solitary and social play. Selection for increased intrinsic motivation to manipulate objects likely also played an important role in the evolution of hominin tool use.

Social equality in the number of choice options is represented in the ventromedial prefrontal cortex.

A distinct aspect of the sense of fairness in humans is that we care not only about equality in material rewards but also about equality in nonmaterial values. One such value is the opportunity to choose freely among many options, often regarded as a fundamental right to economic freedom. In modern developed societies, equal opportunities in work, living, and lifestyle are enforced by antidiscrimination laws. Despite the widespread endorsement of equal opportunity, no studies have explored how people assign value to it. We used functional magnetic resonance imaging to identify the neural substrates for subjective valuation of equality in choice opportunity. Participants performed a two-person choice task in which the number of choices available was varied across trials independently of choice outcomes. By using this procedure, we manipulated the degree of equality in choice opportunity between players and dissociated it from the value of reward outcomes and their equality. We found that activation in the ventromedial prefrontal cortex (vmPFC) tracked the degree to which the number of options between the two players was equal. In contrast, activation in the ventral striatum tracked the number of options available to participants themselves but not the equality between players. Our results demonstrate that the vmPFC, a key brain region previously implicated in the processing of social values, is also involved in valuation of equality in choice opportunity between individuals. These findings may provide valuable insight into the human ability to value equal opportunity, a characteristic long emphasized in politics, economics, and philosophy.

In previous work assessing memory at various levels of representation, namely the surface form, textbase, and situation model levels, participants read texts but were otherwise not actively engaged with the texts. The current study tested the influence of active engagement with the material via note taking, along with the opportunity to review such notes, and the modality of presentation (text vs. spoken). The influence of these manipulations was assessed both immediately and 1 week later. In Experiment 1 participants read a text, whereas in Experiment 2 participants watched a video recording of the material being read as a lecture. For each experiment the opportunity to take notes was manipulated within participants, and the opportunity to review these notes before the test was manipulated between participants. Note taking improved performance at the situation model level in both experiments, although there was also some suggestion of benefit for the surface form. Thus, active engagement with material, such as note taking, appears to have the greatest benefit at the deeper levels of understanding.

Summary Small-molecule kinase inhibitors have typically been designed to inhibit wild-type kinases rather than the mutant forms that frequently arise in diseases such as cancer. Mutations can have serious clinical implications by increasing kinase catalytic activity or conferring therapeutic resistance. To identify opportunities to repurpose inhibitors against disease-associated mutant kinases, we conducted a large-scale functional screen of 183 known kinase inhibitors against 76 recombinant, mutant kinases. The results revealed lead compounds with activity against clinically important mutant kinases including ALK, LRRK2, RET, and EGFR as well as unexpected opportunities for repurposing FDA-approved kinase inhibitors as leads for additional indications. Furthermore, using T674I PDGFRα as an example, we show how single-dose screening data can provide predictive structure-activity data to guide subsequent inhibitor optimization. This study provides a resource for the development of inhibitors against numerous disease-associated mutant kinases and illustrates the potential of unbiased profiling as an approach to compound-centric inhibitor development.

Background The capacity of service providers in the public sector to deliver inclusive services is essential to implement strategies that will allow the full participation of disabled youth in development opportunities in the rural context. Objectives This article sets out to describe the capacity of service providers in facilitating the participation of disabled youth in economic development opportunities. Method An instrumental, embedded single case study informed the research design. The sample consisted of five disabled youth, four family members and six service providers. Data was gathered through in depth individual interviews and focus group discussions. Data analysis was done inductively and thematically. In the discussion, the interpretation used organisational capacity elements as a framework. Results The findings indicate a perception of disability as a multifaceted and challenging issue with different orientations to service delivery, based on the understanding of the impairment and disability. There is a strong focus on impairment and negative attitudes. Discussion An asset-building approach could facilitate awareness of the capacities of disabled youth and thus shift negative attitudes to enabling attitudes. The vague strategies for youth and women reflect an organisational attitude that seems non-committal to its core agenda of inclusive development, which would ensure equal opportunities for participation by disabled youth. Conclusion An appreciative process of facilitating a deeper understanding of the needs of disabled youth would assist service providers to reconceptualise disability within an expansive framework of equal opportunities and active citizenship.

Mice from replicate lines, selectively bred based on high daily wheel-running rates, run more total revolutions and at higher average speeds than do mice from nonselected control lines. Based on this difference it was assumed that selected mice would find the opportunity to run in a wheel a more efficacious consequence. To assess this assumption within an operant paradigm, mice must be trained to make a response to produce the opportunity to run as a consequence. In the present study an autoshaping procedure was used to compare the acquisition of lever pressing reinforced by the opportunity to run for a brief opportunity (i.e., 90 s) between selected and control mice and then, using an operant procedure, the effect of the duration of the opportunity to run on lever pressing was assessed by varying reinforcer duration over values of 90 s, 30 min, and 90 s. The reinforcement schedule was a ratio schedule (FR 1 or VR 3). Results from the autoshaping phase showed that more control mice met a criterion of responses on 50% of trials. During the operant phase, when reinforcer duration was 90 s, almost all control, but few selected mice completed a session of 20 reinforcers; however, when reinforcer duration was increased to 30 min almost all selected and control mice completed a session of 20 reinforcers. Taken together, these results suggest that selective breeding based on wheel-running rates over 24 hr may have altered the motivational system in a way that reduces the reinforcing value of shorter running durations. The implications of this finding for these mice as a model for attention deficit hyperactivity disorder (ADHD) are discussed. It also is proposed that there may be an inherent trade-off in the motivational system for activities of short versus long duration.

The reinforcement schedule was a ratio schedule (FR 1 or VR 3). Results from the autoshaping phase showed that more control mice met a criterion of responses on 50% of trials.

The present article summarizes the results from the Active Healthy Kids Canada 2012 Report Card on Physical Activity for Children and Youth. The Report Card assessed the physical activity levels of Canadian children and youth nationally, and the initiatives of public and nongovernment sectors to promote and facilitate physical activity opportunities for children and youth in Canada. Based on a comprehensive collection of data that were analyzed and/or published in 2011, 24 indicators relating to physical activity were graded. The Physical Activity Levels indicator, the core indicator of the Report Card, was graded an ‘F’ for the sixth consecutive year. Although the majority of grades remained unchanged from the previous year, four grades improved and two worsened. These results suggest that few Canadian children and youth have sufficient physical activity levels, and that greater efforts are required across sectors to promote and facilitate physical activity opportunities for children and youth in Canada.

Racial-ethnic disparities in physical activity present important challenges to population health. Public parks provide access to free or low-cost physical activity opportunities, but it is unclear to what extent parks are utilized by various race-ethnic groups in diverse urban settings. Here, we examine racial ethnic differences in park use and physical activity among adult residents (n = 7506) living within 1 mi of 50 parks in the city of Los Angeles. In multivariate analyses, we find few differences among race-ethnic groups in terms of their frequency of having visited the park in the past 7 days; however, we find numerous differences in how the groups used the park and in their levels of physical activity: Blacks and English-speaking Latinos were less likely than whites to report being physically active, exercising in the park, and exercising outside the park; Spanish-speaking Latinos were equally likely as whites to report exercising in park but less likely to report exercising outside the park and more likely to report using the parks for social interactions; Asians/Pacific Islanders (PI)/others were more likely than whites to report visiting the park in the past 7 days and using the parks for social interactions. Urban parks appear to be an important resource for physical activity and socialization, in particular among Spanish-speaking Latino and Asians/PI groups. Additional efforts may be needed for other racial-ethnic minorities to experience the same benefits.
