Sex markets (the spatially and culturally bounded arenas) that shape bisexual behavior among Latino men have been utilized as a deterministic concept without a sufficient focus on the ability of individuals to make autonomous decisions within such arenas. We nuance the theory of sex markets using the concept of sexual opportunity structures to investigate the ways in which behaviorally bisexual Latino men in the urban metropolis of New York City navigate sexual geographies, cultural meaning systems, sexual scripts, and social institutions to configure their bisexual behaviors. Drawing on 60 in-depth interviews with bisexual Latino men in New York City, we first describe and analyze venues that constitute sexual geographies that facilitate and impede sexual interaction. These also allow for a degree of autonomy in decision-making, as men travel throughout the urban sexual landscape and sometimes even manage to reject norms, such as those imposed by Christian religion. We explore some of the cultural meaning systems and social institutions that regulate sex markets and influence individual decision-making. Secrecy and discretion-regulated by the family, masculinity, migration, and religion-only partially shaped sexual behavior and relationships. These factors create a flux in "equilibrium" in bisexual sex markets in which sociocultural-economic structures constantly interplay with human agency. This article contributes to the literature in identifying dynamic spaces for sexual health interventions that draw on individual agency and empowerment.

2017-01-01

This paper provides a comprehensive examination of the spatial and career mobility of China’s labor population. The paper integrates theories on stratification and social change and exploits the innovative design and measurement of the China Labor-force Dynamics Survey to minimize the under-coverage problem of the rural-urban migratory experience. Our analysis provides several fresh findings: (1) at-birth rural household registration (hukou) status leads to a greater probability of spatial mobility and career advancement than at-birth urban hukou status does; (2) education and gender differentiates rural-origin people, increasing the heterogeneity of urban labor and decreasing the heterogeneity of rural labor; (3) hukou policy relaxation favors later cohorts over earlier cohorts; and (4) among demographically comparable people, having experienced spatial mobility is correlated with having career advancement experience. Work organizations are found to be the arena where the two dimensions of mobility can happen jointly. Our findings provide a rich context for understanding the management and organization of Chinese labor. PMID:29129981

City rats: insight from rat spatial behavior into human cognition in urban environments.

PubMed

Yaski, Osnat; Portugali, Juval; Eilam, David

2011-09-01

The structure and shape of the urban environment influence our ability to find our way about in the city. Understanding how the physical properties of the environment affect spatial behavior and cognition is therefore a necessity. However, there are inherent difficulties in empirically studying complex and large-scale urban environments. These include the need to isolate the impact of specific urban features and to acquire data on the physical activity of individuals. In the present study, we attempted to overcome the above obstacles and examine the relation between urban environments and spatial cognition by testing the spatial behavior of rats. This idea originated from the resemblance in the operative brain functions and in the mechanisms and strategies employed by humans and other animals when acquiring spatial information and establishing an internal representation, as revealed in past studies. Accordingly, we tested rats in arenas that simulated a grid urban layout (e.g. Manhattan streets) and an irregular urban layout (e.g. Jerusalem streets). We found that in the grid layout, rat movement was more structured and extended over a greater area compared with their restricted movement in the irregular layout. These movement patterns recall those of humans in respective urban environments, illustrating that the structure and shape of the environment affect spatial behavior similarly in humans and rats. Overall, testing rats in environments that simulate facets of urban environments can provide new insights into human spatial cognition in urban environments.

Neoliberalism and indigenous knowledge: Māori health research and the cultural politics of New Zealand's "National Science Challenges".

PubMed

Prussing, Erica; Newbury, Elizabeth

2016-02-01

In 2012-13 the Ministry of Business, Innovation and Employment (MBIE) in New Zealand rapidly implemented a major restructuring of national scientific research funding. The "National Science Challenges" (NSC) initiative aims to promote greater commercial applications of scientific knowledge, reflecting ongoing neoliberal reforms in New Zealand. Using the example of health research, we examine the NSC as a key moment in ongoing indigenous Māori advocacy against neoliberalization. NSC rhetoric and practice through 2013 moved to marginalize participation by Māori researchers, in part through constructing "Māori" and "science" as essentially separate arenas-yet at the same time appeared to recognize and value culturally distinctive forms of Māori knowledge. To contest this "neoliberal multiculturalism," Māori health researchers reasserted the validity of culturally distinctive knowledge, strategically appropriated NSC rhetoric, and marshalled political resources to protect Māori research infrastructure. By foregrounding scientific knowledge production as an arena of contestation over neoliberal values and priorities, and attending closely to how neoliberalizing tactics can include moves to acknowledge cultural diversity, this analysis poses new questions for social scientific study of global trends toward reconfiguring the production of knowledge about health. Study findings are drawn from textual analysis of MBIE documents about the NSC from 2012 to 2014, materials circulated by Māori researchers in the blogosphere in 2014, and ethnographic interviews conducted in 2013 with 17 Māori health researchers working at 7 sites that included university-based research centers, government agencies, and independent consultancies.

Tinea pedis: the etiology and global epidemiology of a common fungal infection.

PubMed

Ilkit, Macit; Durdu, Murat

2015-01-01

Tinea pedis, which is a dermatophytic infection of the feet, can involve the interdigital web spaces or the sides of the feet and may be a chronic or recurring condition. The most common etiological agents are anthropophiles, including Trichophyton rubrum sensu stricto, which is the most common, followed by Trichophyton interdigitale and Epidermophyton floccosum. There has been a change in this research arena, necessitating a re-evaluation of our knowledge on the topic from a multidisciplinary perspective. Thus, this review aimed to provide a solid overview of the current status and changing patterns of tinea pedis. The second half of the twentieth century witnessed a global increase in tinea pedis and a clonal spread of one major etiologic agent, T. rubrum. This phenomenon is likely due to increases in urbanization and the use of sports and fitness facilities, the growing prevalence of obesity and the aging population. For optimal patient care and management, the diagnosis of tinea pedis should be verified by microbiological analysis. In this review, we discuss the epidemiology, clinical forms, complications and mycological characteristics of tinea pedis and we highlight the pathogenesis, prevention and control parameters of this infection.

Rural-urban disparity in knowledge and compliance with traffic signs among young commercial motorcyclists in selected local government areas in Oyo State, Nigeria.

2017-06-01

This study compared knowledge and compliance with traffic signs among young commercial motorcyclists in rural and urban communities in Oyo state, Nigeria. Information on knowledge and compliance with 10 common traffic signs was obtained from 149 rural and 113 urban commercial motorcyclists aged 18-35 years. Aggregate knowledge scores were computed and categorized as good (≥5) and poor (<5) knowledge. Overall, 98.7% rural versus 61.1% urban motorcyclists had poor knowledge of traffic signs (p < 0.05). After controlling for age, level of education and years of commercial riding, motorcyclists in the rural areas were more likely to have poor knowledge of the traffic signs (OR = 58.15; 95% CI = 11.96-282.79). A higher proportion of rural than urban motorcyclists never obeyed any of the traffic signs. Young rural commercial motorcyclists' knowledge and compliance with the road signs was poorer than their urban counterparts. Interventions to improve the rural motorcyclists' knowledge and ultimately compliance with road signs are urgently required.

Society, materiality, resilience and sustainability: inquiries from the fields of industrial waste management, urban climate science and eco-urbanism

NASA Astrophysics Data System (ADS)

MacKillop, Fionn

2018-06-01

This paper aims to investigate the links between materiality and society at a conceptual level, using examples from the author's decade of research in several fields relevant to the issue. With current talk of the need for `sustainability' and `resilience' reaching fever pitch in industry, politics and other arenas, there is a regrettable tendency to muddle the meaning of these words. Drawing on original research carried out in the UK, China, Germany, and Australia, and using the conceptual approaches of actor-network theory (ANT) and urban political ecology (UPE), the author invites us to re-engage with the materiality of society and how we, as businesses, consumers and thinkers, can advance sustainability and resilience through this re-engagement. We will ask what sustainability and resilience mean, for whom and in what context. We will also look at how we can shift thinking and reinvigorate these words, by contributing to the dialogue between the social sciences and business and industry. Specific examples will be taken from the UK and Chinese steel industries; climate-sensitive urban design in Manchester and Stuttgart; and housing construction and affordability in Scotland and Australia, thus covering a wide range of issues related to urban sustainability and resilience in relation to materiality.

Arena geometry and path shape: when rats travel in straight or in circuitous paths?

PubMed

Yaski, Osnat; Portugali, Juval; Eilam, David

2011-12-01

We show here that the global geometry of the environment affects the shape of the paths of travel in rats. To examine this, individual rats were introduced into an unfamiliar arena. One group of rats (n=8) was tested in a square arena (2 m × 2 m), and the other group (n=8) in a round arena (2 m diameter). Testing was in a total darkness, since in the absence of visual information the geometry is not perceived immediately and the extraction of environment shape is slower. We found that while the level of the rats' activity did not seem to differ between both arenas, path shape differed significantly. When traveling along the perimeter, path shape basically followed the arena walls, with perimeter paths curving along the walls of the round arena, while being straight along the walls of the square arena. A similar impact of arena geometry was observed for travel away from the arena walls. Indeed, when the rats abandoned the arena walls to crosscut through the center of the arena, their center paths were circuitous in the round arena and relatively straight in the square arena. We suggest that the shapes of these paths are exploited for the same spatial task: returning back to a familiar location in the unsighted environment. Copyright © 2011 Elsevier B.V.

2017-04-01

Heat waves threaten human health given the fast changing climatic scenarios in the recent past. Adaptation to heat waves would take place when people perceive their impacts based on their knowledge. The present study examines perception level and its determinants resulting in adaptation to heat waves in Pakistan. The study used cross-sectional data from urban and peri-urban respondents of Faisalabad District. The study employs a health belief model to assess risk perception among the respondents. Logistic model is used to determine factors affecting level of knowledge, perception and adaptation to heat waves. Around 30% of peri-urban respondents have a low level of knowledge about the fatal impacts of heat waves. Risk perception of heat waves is very low among urban (57%) and peri-urban (66%) respondents. Households' knowledge on heat waves is significantly related to age, gender, education, wealth and access to health services. Determinants of perception include knowledge of heat waves, age and joint effect of marital status and knowledge while income level, family size, urban/peri-urban background, perceived barriers, perceived benefits and cues to action significantly affect adaptation to heat waves. To reduce deadly health impacts, mass awareness campaigns are needed to build perception and improve adaptation to heat waves.

Concussion Knowledge and Reporting Behavior Differences Between High School Athletes at Urban and Suburban High Schools.

2017-09-01

We determined differences in knowledge of concussion and reporting behaviors of high school athletes attending urban and suburban high schools, and whether a relationship exists between underreporting and access to an athletic trainer in urban schools. High school athletes (N = 715) from 14 high schools completed a validated knowledge of concussion survey consisting of 83 questions. The independent variable was school type (urban/suburban). We examined the proportion of athletes who correctly identified signs and symptoms of concussion, knowledge of concussion and reasons why high school athletes would not disclose a potential concussive injury across school classification. Data were analyzed using descriptive, non-parametric, and inferential statistics. Athletes attending urban schools have less concussion knowledge than athletes attending suburban schools (p < .01). Athletes attending urban schools without an athletic trainer have less knowledge than urban athletes at schools with an athletic trainer (p < .01) There was no significant relationship between reporting percentage and school type (p = .73); however, significant relationships exist between AT access at urban schools and 10 reasons for not reporting. Concussion education efforts cannot be homogeneous in all communities. Education interventions must reflect the needs of each community. © 2017, American School Health Association.

Carbon Monoxide Exposure in Youth Ice Hockey.

Macnow, Theodore; Mannix, Rebekah; Meehan, William P

2017-11-01

To examine the effect of ice resurfacer type on carboxyhemoglobin levels in youth hockey players. We hypothesized that players in arenas with electric resurfacers would have normal, stable carboxyhemoglobin levels during games, whereas those in arenas with internal combustion engine (IC) resurfacers would have an increase in carboxyhemoglobin levels. Prospective cohort study. Enclosed ice arenas in the northeastern United States. Convenience sample of players aged 8 to 18 years old in 16 games at different arenas. Eight arenas (37 players) used an IC ice resurfacer and 8 arenas (36 players) an electric resurfacer. Carboxyhemoglobin levels (SpCO) were measured using a pulse CO-oximeter before and after the game. Arena air was tested for carbon monoxide (CO) using a metered gas detector. Players completed symptom questionnaires. The change in SpCO from pregame to postgame was compared between players at arenas with electric versus IC resurfacers. Carbon monoxide was present at 6 of 8 arenas using IC resurfacers, levels ranged from 4 to 42 parts per million. Carbon monoxide was not found at arenas with electric resurfacers. Players at arenas with IC resurfacers had higher median pregame SpCO levels compared with those at electric arenas (4.3% vs 1%, P < 0.01). Players in the IC group also had a significant increase in their SpCO level during a hockey game compared with those in the electric group (2.8% vs 1%, P = 0.01). There were no significant differences in symptom scores. Players at arenas operating IC resurfacers had significantly higher SpCO levels. Youth hockey players in arenas with IC resurfacers have an increase in carboxyhemoglobin during games and have elevated baseline carboxyhemoglobin levels compared with players at arenas with electric resurfacers. Electric resurfacers decrease the risk of CO exposure.

Architectural and Urban Identity Transformation of Eskisehir - An Anatolian City

NASA Astrophysics Data System (ADS)

Kandemir, Ozlem

2017-10-01

City is the arena where we identify ourselves and interact with others and our environment; cities are epicentres of interaction, transition and fusion of different communities and their cultures. Thus, it is important to discuss the elements of change and their consequences in architectural - urban spaces and their products in the context of identity. Urban identity can be defined as the impression invoked on its inhabitants by the environmental, historical, sociocultural and spatial values. Both architectural and urban identity have a dynamic structure, susceptive to every change on both social and administrative structure. Both global and national economic fluctuations in the last decades and industrialisation throughout the 20th century caused dramatic and diverse changes in the conditions of life, consumption forms, the perception of time and space consequently transforming architecture and city. The changes in all the different aspects of the city life and structure with time cause transformation of architecture and urban identity. This dynamism caused by changes and new formations in the cultural life and environmental conditions also leads to transforming customs and the ways we occupy/use/live in a place. Consequently, these changes and new social norms that can transform the way we occupy a space and our demands from a place can be asserted. All new requirements caused by these new conditions of urban life transform the existing architecture and spaces. In this presentation, the transformation of the architectural and urban identity of Eskisehir will be discussed through its dynamics like architectural and urban transformation, industry and politics.

Urban as a determinant of health.

Cities are the predominant mode of living, and the growth in cities is related to the expansion of areas that have concentrated disadvantage. The foreseeable trend is for rising inequities across a wide range of social and health dimensions. Although qualitatively different, this trend exists in both the developed and developing worlds. Improving the health of people in slums will require new analytic frameworks. The social-determinants approach emphasizes the role of factors that operate at multiple levels, including global, national, municipal, and neighborhood levels, in shaping health. This approach suggests that improving living conditions in such arenas as housing, employment, education, equality, quality of living environment, social support, and health services is central to improving the health of urban populations. While social determinant and multilevel perspectives are not uniquely urban, they are transformed when viewed through the characteristics of cities such as size, density, diversity, and complexity. Ameliorating the immediate living conditions in the cities in which people live offers the greatest promise for reducing morbidity, mortality, and disparities in health and for improving quality of life and well being.

2011-02-01

This paper studies the smallpox vaccination in Argentina since 1870, when these discussions were initiated until the 1910s, when they were extended to the rest of the country. We analyze immunization practices implemented prior to the compulsory vaccination law, passed in 1886 for the Capital and in 1904 for the rest of the country. Such a move found resistance from different sectors. Its approval depended on the consequences of modernization and urbanization, the weight of hygienists in the political arena, and its extension depended on a different administrative conception, incorporating new areas and sectors to the national scenario.

Residential Knowledge of Native Tree Species: A Case Study of Residents in Four Southern Ontario Municipalities

Almas, Andrew D.; Conway, Tenley M.

2017-01-01

In the past decade, municipalities across North America have increased investment in their urban forests in an effort to maintain and enhance the numerous benefits provided by them. Some municipalities have now drafted long-term urban forest management plans that emphasize the planting of native trees, to improve ecological integrity, and participation of residents, since the majority of urban trees are typically located on residential property. Yet it is unclear if residents are familiar with native trees or municipalities' urban forest management goals. Through a case study of southern Ontario municipalities, we administered a survey exploring residents' ability to correctly label common tree species as native or non-native, as well as their knowledge of urban forest management plans to test four hypotheses: 1) residents in municipalities with an urban forest management plans will be more knowledgeable about the native status of common street trees; 2) residents who have lived in the area longer will have greater knowledge; 3) knowledge level will be correlated with education level, ethnicity, and income; and 4) residents' knowledge will be related to having planted trees on their property. Our results indicate that residents are better able to identify common native trees than correctly determine which trees are non-native, although knowledge levels are generally low. Knowledge was significantly related to length of residency and tree planting experience, supporting hypotheses 2 and 4. These results highlight the importance of experience and local knowledge acquisition in relation to basic knowledge about urban trees, and also point to the failures of resident outreach within the case study municipalities.

The 'medical body' as philosophy's arena.

PubMed

Evans, M

2001-01-01

Medicine, as Byron Good argues, reconstitutes the human body of our daily experience as a "medical body," unfamiliar outside medicine. This reconstitution can be seen in two ways: (i) as a salutary reminder of the extent to which the reality even of the human body is constructed; and (ii) as an arena for what Stephen Toulmin distinguishes as the "intersection" of natural science and history, in which many of philosophy's traditional (and traditionally abstract) questions are given concrete and urgent form. This paper begins by examining a number of dualities between the medical body and the body familiar in daily experience. Toulmin's epistemological analysis of clinical medicine as combining both universal and existential knowledge is then considered. Their expression, in terms of attention, respectively, to natural science and to personal history, is explored through the epistemological contrasts between the medical body and the familiar body, noting the traditional philosophical questions which they in turn illustrate.

Human moral judgement may have evolved to maximize the individual's welfare given parochial culturally constructed moral systems. If so, then moral condemnation should be more severe when transgressions are recent and local, and should be sensitive to the pronouncements of authority figures (who are often arbiters of moral norms), as the fitness pay-offs of moral disapproval will primarily derive from the ramifications of condemning actions that occur within the immediate social arena. Correspondingly, moral transgressions should be viewed as less objectionable if they occur in other places or times, or if local authorities deem them acceptable. These predictions contrast markedly with those derived from prevailing non-evolutionary perspectives on moral judgement. Both classes of theories predict purportedly species-typical patterns, yet to our knowledge, no study to date has investigated moral judgement across a diverse set of societies, including a range of small-scale communities that differ substantially from large highly urbanized nations. We tested these predictions in five small-scale societies and two large-scale societies, finding substantial evidence of moral parochialism and contextual contingency in adults' moral judgements. Results reveal an overarching pattern in which moral condemnation reflects a concern with immediate local considerations, a pattern consistent with a variety of evolutionary accounts of moral judgement.

Shommu, Nusrat S

2017-01-01

Knowledge translation is an essential and emerging arena in healthcare research. It is the process of aiding the application of research knowledge into clinical practice or policymaking. Individuals at all levels of the health care system, including patients, healthcare professionals, and policymakers, are affected by the gaps that exist between research evidence and practice; the process of knowledge translation plays a role in bridging these gaps and incorporating high-quality clinical research into decision-making. Cardiovascular disease (CVD) management is a crucial area of healthcare where information gaps are known to exist. Although Japan has one of the lowest risks and mortality rates from CVDs, an increasing trend of cardiovascular incidence and changes in the risk factor conditions have been observed in recent years. This article provides an overview of knowledge translation and its importance in the cardiovascular health of the Japanese population, and describes the key steps of a typical knowledge translation strategy.

Fusing terrain and goals: agent control in urban environments

NASA Astrophysics Data System (ADS)

Kaptan, Varol; Gelenbe, Erol

2006-04-01

The changing face of contemporary military conflicts has forced a major shift of focus in tactical planning and evaluation from the classical Cold War battlefield to an asymmetric guerrilla-type warfare in densely populated urban areas. The new arena of conflict presents unique operational difficulties due to factors like complex mobility restrictions and the necessity to preserve civilian lives and infrastructure. In this paper we present a novel method for autonomous agent control in an urban environment. Our approach is based on fusing terrain information and agent goals for the purpose of transforming the problem of navigation in a complex environment with many obstacles into the easier problem of navigation in a virtual obstacle-free space. The main advantage of our approach is its ability to act as an adapter layer for a number of efficient agent control techniques which normally show poor performance when applied to an environment with many complex obstacles. Because of the very low computational and space complexity at runtime, our method is also particularly well suited for simulation or control of a huge number of agents (military as well as civilian) in a complex urban environment where traditional path-planning may be too expensive or where a just-in-time decision with hard real-time constraints is required.

Contrasting effects of visiting urban green-space and the countryside on biodiversity knowledge and conservation support.

PubMed

Coldwell, Deborah F; Evans, Karl L

2017-01-01

Conservation policy frequently assumes that increasing people's exposure to green-space enhances their knowledge of the natural world and desire to protect it. Urban development is, however, considered to be driving declining connectedness to nature. Despite this the evidence base supporting the assumption that visiting green-spaces promotes biodiversity knowledge and conservation support, and the impacts of urbanization on these relationships, is surprisingly limited. Using data from door-to-door surveys of nearly 300 residents in three pairs of small and large urban areas in England we demonstrate that people who visit green-space more regularly have higher biodiversity knowledge and support for conservation (measured using scales of pro-environmental behavior). Crucially these relationships only arise when considering visits to the countryside and not the frequency of visits to urban green-space. These patterns are robust to a suite of confounding variables including nature orientated motivations for visiting green-space, socio-economic and demographic factors, garden-use and engagement with natural history programs. Despite this the correlations that we uncover cannot unambiguously demonstrate that visiting the countryside improves biodiversity knowledge and conservation support. We consider it likely, however, that two mechanisms operate through a positive feedback loop i.e. increased visits to green-space promote an interest in and knowledge of biodiversity and support for conservation, which in turn further increase the desire to visit green-space and experience nature. The intensity of urbanization around peoples' homes, but not city size, is negatively associated with their frequency of countryside visits and biodiversity knowledge. Designing less intensely urbanized cities with good access to the countryside, combined with conservation policies that promote access to the countryside thus seems likely to maximize urban residents' biodiversity knowledge and support for conservation.

The explicit and implicit dance in psychoanalytic change.

PubMed

Fosshage, James L

2004-02-01

How the implicit/non-declarative and explicit/declarative cognitive domains interact is centrally important in the consideration of effecting change within the psychoanalytic arena. Stern et al. (1998) declare that long-lasting change occurs in the domain of implicit relational knowledge. In the view of this author, the implicit and explicit domains are intricately intertwined in an interactive dance within a psychoanalytic process. The author views that a spirit of inquiry (Lichtenberg, Lachmann & Fosshage 2002) serves as the foundation of the psychoanalytic process. Analyst and patient strive to explore, understand and communicate and, thereby, create a 'spirit' of interaction that contributes, through gradual incremental learning, to new implicit relational knowledge. This spirit, as part of the implicit relational interaction, is a cornerstone of the analytic relationship. The 'inquiry' more directly brings explicit/declarative processing to the foreground in the joint attempt to explore and understand. The spirit of inquiry in the psychoanalytic arena highlights both the autobiographical scenarios of the explicit memory system and the mental models of the implicit memory system as each contributes to a sense of self, other, and self with other. This process facilitates the extrication and suspension of the old models, so that new models based on current relational experience can be gradually integrated into both memory systems for lasting change.

2012-01-01

Open field behavior is well known to depend on physical characteristics of the apparatus. However many of such effects are poorly described especially with using of modern methods of behavioral registration and analysis. The previous results of experiments on the effect of arena size on behavior are not numerous and contradictory. We compared the behavioral scores of four groups of C57BL/6 mice in round open field arenas of four different sizes (diameter 35, 75, 150 and 220 cm). The behavior was registered and analyzed using Noldus EthoVision, WinTrack and SegmentAnalyzer software. A significant effect of arena size was found. Traveled distance and velocity increased, but not in proportion to increase of arena size. Moreover a significant effect on segment characteristics of the trajectory was revealed. Detailed behavior analysis revealed drastic differences in trajectory structure and number of rears between smaller (35 and 75 cm) and bigger (150 and 220 cm) arenas. We conclude, that the character of exploration in smaller and bigger arenas depends on relative size of central open zone in arena. Apparently its extension increases the motivational heterogeneity of space, that requires another than in smaller arenas, strategy of exploration.

Emerging Standards for Medical Logic

Clayton, Paul D.; Hripcsak, George; Pryor, T. Allan

1990-01-01

Sharing medical logic has traditionally occurred in the form of lectures, conversations, books and journals. As knowledge based computer systems have demonstrated their utility in the health care arena, individuals have pondered the best way to transfer knowledge in a computer based representation (1). A simple representation which allows the knowledge to be shared can be constructed when the knowledge base is modular. Within this representation, units have been named Medical Logic Modules (MLM's) and a syntax has emerged which would allow multiple users to create, criticize, and share those types of medical logic which can be represented in this format. In this paper we talk about why standards exist and why they emerge in some areas and not in others. The appropriateness of using the proposed standards for medical logic modules is then examined against this broader context.

These cases were selected to span a range of geographic scales and topical scopes; all three are examples of urban researcher-practitioner networks in which the authors are situated to comment on reflexively. The three cases resemble institutional structures described in the knowledge co-production literature, including participatory research, a hybrid organization of scientists and managers, and a community of practice. We find that trust, embeddedness, new approaches by both practitioners and researchers, and blending of roles all serve to recognize multiple forms of capability, expertise, and ways of knowing. We discuss the impacts of knowledge co-production and the ways in which hybrid institutional forms can enable its occurrence.

Foulkes, Julia L

2010-01-01

Lincoln Center for the Performing Arts in Manhattan and the revitalization of the Brooklyn Academy of Music in Brooklyn offer insights into the intersection of arts and urbanization after World War II. This intra-city comparison shows the aggrandizing pull of the international arena in the shaping of Lincoln Center and the arts it featured in contrast to the local focus and debate that transformed how BAM fit into its Brooklyn neighborhood. The performing arts, bound as they are to a moment fused in space and time, reveal the making of place within grandiose formal buildings as well as outside on the streets that surround them—and it is, perhaps, that tensile connection between stages and streets that informs the relevancy of both the institution and the arts it features. At a time when the suburbs pulled more and more people, the arts provided a counterforce in cities, as magnet and stimulus. The arts were used as compensation for the demolition and re-building of a neighborhood in urban renewal, but they also exposed the more complex social dynamics that underpinned the transformation of the mid-20th century American city from a segregated to a multi-faceted place.

Lack of access to information and knowledge about mother and child health was identified as a major contributor to poor maternal and child health in Nigeria. The Partnership for Maternal, Newborn and Child Health (PMNCH) has recognized mapping the knowledge management of Maternal Newborn and Child Health (MNCH) as one of the major strategies to be deployed in improving the health of these vulnerable groups. The main aim of this study is to map the knowledge management resources of Maternal, Newborn and Child Health (MNCH) in rural and urban settings of Ilorin West LGA of Kwara state Nigeria. It is a descriptive cross-sectional study with a comparative analysis of findings from urban and rural settings. Epi-mapping was used to carve out the LGA and map responses. The p-value of less than 0.05 was considered significant at 95% confidence level. The study showed that traditional leader was responsible for more than half of the traditional way of obtaining information by rural (66.7%) and urban (56.2%) respondents while documentation accounts for the main MNCH knowledge preservation for the rural (40.6%) and the urban (50%) dwellers. Traditional leaders (32.2%) and elders (46.7%) were the main people responsible for dissemination of knowledge in rural areas whereas elders (35.9%) and Parents (19.9%) were the main people responsible in urban areas. It was concluded that traditional and family institutions are important in the knowledge management of MNCH in both rural and urban settings of Nigeria.

In open field arenas, Drosophila adults exhibit a preference for arena boundaries over internal walls and open regions. Herein, we investigate the nature of this preference using phenomenological modeling of locomotion to determine whether local arena features and constraints on movement alone are sufficient to drive positional preferences within open field arenas of different shapes and with different internal features. Our model has two components: directional persistence and local wall force. In regions far away from walls, the trajectory is entirely characterized by a directional persistence probability, , for each movement defined by the step size, , and the turn angle, . In close proximity to walls, motion is computed from and a local attractive force which depends on the distance between the fly and points on the walls. The directional persistence probability was obtained experimentally from trajectories of wild type Drosophila in a circular open field arena and the wall force was computed to minimize the difference between the radial distributions from the model and Drosophila in the same circular arena. The two-component model for fly movement was challenged by comparing the positional preferences from the two-component model to wild type Drosophila in a variety of open field arenas. In most arenas there was a strong concordance between the two-component model and Drosophila. In more complex arenas, the model exhibits similar trends, but some significant differences were found. These differences suggest that there are emergent features within these complex arenas that have significance for the fly, such as potential shelter. Hence, the two-component model is an important step in defining how Drosophila interact with their environment. PMID:23071591

Video studies of passage by Anopheles gambiae mosquitoes through holes in a simulated bed net: effects of hole size, hole orientation and net environment.

PubMed

Sutcliffe, James; Colborn, Kathryn L

2015-05-13

Holes in netting provide potential routes for mosquitoes to enter ITNs. Despite this, there is little information on how mosquitoes respond to holes in bed nets and how their responses are affected by hole size, shape and orientation or by ambient conditions around the net. Female Anopheles gambiae (G3) were recorded in a simulated bed net consisting of two sizes of untreated netting-covered behavioural arenas placed above and beside (to simulate the bed net roof and sides respectively) the experimenter who was a source of host cues from 'inside' the net. A round hole of 9 mm or 13 mm diameter was cut into the centre of the netting of each arena. Videos of unfed female mosquitoes in arenas were analysed for time spent flying, walking and standing still and for exit through the hole. The effects of the experimenter on temperature and relative humidity around the simulated net were also measured. Mosquitoes were significantly more active in overhead arenas than in arenas to the side. Hole passage was significantly more likely in smaller arenas than larger ones and for larger holes than smaller ones. In arenas to the side, hole passage rate through small holes was about 50% less likely than what could be explained by area alone. Passage rate through holes in overhead arenas was consistent with hole area. Temperature in arenas did not strongly reflect the experimenter's presence in the simulated net. Relative humidity and absolute humidity in overhead arenas, but not in arenas to the side, were immediately affected by experimenter presence. Higher levels of activity in overhead arenas than in arenas to the side were likely due to the rising heat and humidity plume from the experimenter. Lower than expected passage rates through smaller vertically oriented holes may have been be due to an edge effect that does not apply to horizontally oriented holes. Results suggest that current methods of assessing the importance of physical damage to ITNs may not accurately reflect mosquito entry risk in all cases.

By 1990, the urban population reached 42% in Guatemala, 44% in El Salvador, 43% in Honduras, 59% in Nicaragua, 53% in Costa Rica, and 54% in Panama. The urban population increased mostly in the largest cities, in contrast to Latin America, where secondary cities grew fastest. This trend was particularly true in Managua and San Salvador because of the military conflicts. The only exception was Honduras, where the second city underwent stronger growth. The urban population comprised 51.7% women and 48.3% men in Central America. The segregation and polarization of social classes was also increasing because of increased poverty and unemployment during the 1980s. This was partly caused by the increasing privatization of public services, decentralization, and the reinforcement of local governments, which all ensued from the structural readjustment programs of the International Monetary Fund. This neoliberal model of economic development in the short run resulted in increased poverty and unemployment for the urban populations. In 1982, the informal sector represented 29% of the total employment in Central America, and its share reached 40% in Managua and San Salvador. Urban unemployment increased from 2.2% in 1980 to 12% in 1988 in Guatemala; from 8.8% to 13.1% in Honduras; and from 10.4% to 20.8% in Panama. In the political arena, the process of democratization was underway, with civil presidents taking power and promoting privatization and deregulation of the economy. There was a close relationship between the urban social structure, the economy, and politics in the region. In Costa Rica, during the Arias administration between 1986 and 1990, a program was implemented creating 80,000 new homes, and in El Salvador there was an increasing demand to find a negotiated solution to the military conflict. These new political and economic perspectives could lead to genuine popular participation in solving urban problems.

Improvement of knowledge, attitudes and practices among urban livestock farmers could have a significant impact on the reduction of many zoonotic infections in urban farming. This study aimed to describe and evaluate weak areas in knowledge, attitudes and practices with regards to brucellosis among urban and peri-urban small-scale dairy farmers in a low income country to generate information essential for control programmes and public health interventions. The cross-sectional study was conducted during six weeks in 2011. The study subjects were small-scale dairy farmers living in the urban and peri-urban area of the capital Dushanbe in Tajikistan. In total, 441 farmers were interviewed using a questionnaire with questions about demographic characteristics, knowledge, attitudes and practices relating to brucellosis. Descriptive statistics were used and a logistic regression model applied to evaluate potential predictors to knowledge about brucellosis. The majority (85%) of the farmers had never heard of brucellosis. Low educational level was found to be associated with low awareness of brucellosis (P = < 0.001). Respondents who talked about animal health issues with family members or friends were less likely to have heard of brucellosis compared to those who often talked to veterinarians (P = 0.03). Sixty three per cent of the participants wanted more information about brucellosis. Seventeen per cent sold unpasteurized dairy products on a regular basis direct to consumers. Almost 30% of the households consumed unpasteurized dairy products on regular basis. A majority of the respondents did not use any protection when handling cows having an abortion or when dealing with aborted materials. Poor knowledge, high-risk behaviours and a willingness to learn more strengthens the logic for including health education as part of control programmes.

Media use and HIV/AIDS knowledge: a knowledge gap perspective.

PubMed

Bekalu, Mesfin Awoke; Eggermont, Steven

2014-12-01

Despite the widespread utilization of the mass media in HIV/AIDS prevention, little is known about the knowledge gap that results from disparities in mass media use. This study examined the relationship between HIV/AIDS-related mass media use and HIV/AIDS-related knowledge among urban and rural residents of northwestern Ethiopia. A hierarchical regression analysis indicated that HIV/AIDS-related mass media use has both sequestering and mainstreaming effects in certain segments of the study population, although it was not a significant predictor of HIV/AIDS-related knowledge in the total population. The knowledge gaps between individuals with high and low education and between individuals who experience high and low levels of interpersonal communication about HIV/AIDS narrowed as HIV/AIDS-related media use increased, but the gap between urban and rural residents widened. The widening gap could be explained by differences in perceptions of information salience and several theoretical assumptions. Current mass media information campaigns, which are often prepared and broadcast from urban centers, may not only fail to improve the HIV/AIDS knowledge of the rural populace but also put rural populations at a disadvantage relative to their urban counterparts. Communication interventions informed by socioecological models might be helpful to redress and/or narrow the widening knowledge gap between urban and rural residents. © The Author (2013).

Argumentation Based Joint Learning: A Novel Ensemble Learning Approach

PubMed Central

Xu, Junyi; Yao, Li; Li, Le

2015-01-01

Recently, ensemble learning methods have been widely used to improve classification performance in machine learning. In this paper, we present a novel ensemble learning method: argumentation based multi-agent joint learning (AMAJL), which integrates ideas from multi-agent argumentation, ensemble learning, and association rule mining. In AMAJL, argumentation technology is introduced as an ensemble strategy to integrate multiple base classifiers and generate a high performance ensemble classifier. We design an argumentation framework named Arena as a communication platform for knowledge integration. Through argumentation based joint learning, high quality individual knowledge can be extracted, and thus a refined global knowledge base can be generated and used independently for classification. We perform numerous experiments on multiple public datasets using AMAJL and other benchmark methods. The results demonstrate that our method can effectively extract high quality knowledge for ensemble classifier and improve the performance of classification. PMID:25966359

Rapid urbanisation generates risks and opportunities for sustainable development. Urban policy and decision makers are challenged by the complexity of cities as social-ecological-technical systems. Consequently there is an increasing need for collaborative knowledge development that supports a whole-of-system view, and transformational change at multiple scales. Such holistic urban approaches are rare in practice. A co-design process involving researchers, practitioners and other stakeholders, has progressed such an approach in the Australian context, aiming to also contribute to international knowledge development and sharing. This process has generated three outputs: (1) a shared framework to support more systematic knowledge development and use, (2) identification of barriers that create a gap between stated urban goals and actual practice, and (3) identification of strategic focal areas to address this gap. Developing integrated strategies at broader urban scales is seen as the most pressing need. The knowledge framework adopts a systems perspective that incorporates the many urban trade-offs and synergies revealed by a systems view. Broader implications are drawn for policy and decision makers, for researchers and for a shared forward agenda.

Hepatitis B and Hepatitis C are serious global public health problems with a prevalence of 10-15% with majority of the cases seen in the developing countries including Pakistan. It is a blood borne infection transmitted by infected blood and blood products through transfusions, contaminated needles, vertical transmission, unsafe sex and reuse of razors by barbers. The literature search so far did not reveal any study comparing knowledge, attitude and practices of hepatitis B & C in barbers working in Urban and rural areas. A comparative cross sectional survey was carried out among barbers of urban and rural areas of Rawalpindi and Islamabad. A structured close ended questionnaire was filled from total of 202 barbers by non-probability convenience sampling technique. Comparative data analysis was done including variables like age, education, knowledge about hepatitis B & C, mode of transmission, role of the blades and media etc. Knowledge about hepatitis B & C was good in urban areas (92%) as compared to those working in the rural areas (68%). Using new blade for every customer was seen in urban (100%) and rural (93%) area. However barbers knowledge about symptoms of the disease (urban 81% & rural 93%) and vaccination trend of Hepatitis B was low. This study showed a marked difference in the knowledge, attitude and practices of the barbers working in the urban and the rural areas. Main focus should be on launching Health education programs and behaviour change communication campaigns for the barbers. Strict regulatory monitoring must be done against unlicensed street barbers.

Pregnancy risk during menstrual cycle: misconceptions among urban men in India.

2017-06-12

In India, where men take most decisions in the family, it is useful that they have adequate knowledge about pregnancy risks during women's menstrual cycles. Since traditional contraceptive methods are still employed by a large population in India, the knowledge regarding the pregnancy risk during the menstrual cycle is indispensable. This research paper attempts to assess the knowledge among urban men in Uttar Pradesh, India about the fertile window of the menstrual cycle; it also attempts to discover the rationales behind the misconceptions about the concept. This study utilizes the baseline data of the Measurement, Learning, and Evaluation project for the Urban Reproductive Health Initiative in Uttar Pradesh. Descriptive Statistics has been used to assess the prevalence of knowledge among urban men regarding the concept. Using the Discriminant Analysis, we also investigate the rationales behind the misconceptions among urban men about the concept. Only one-fifth of the men have the correct knowledge about the concept. Further, we find that education, societal perception, caste, and spousal discussion about the reproductive issues are the primary factors affecting the knowledge about the pregnancy risk during the menstrual cycle. There is an urgent need for sex education in the region to make the urban men more educated about the reproductive process of women; this may reduce unwanted births and abortion due to an unwanted pregnancy as well. The study promotes the higher education and motivates couples to discuss the reproductive health issues among them. In this manner, we can provide better reproductive health to the women of urban India.

New Acoustic Arena Qualified at NASA Glenn's Aero-Acoustic Propulsion Laboratory

NASA Technical Reports Server (NTRS)

Wnuk, Stephen P.

2004-01-01

A new acoustic arena has been qualified in the Aero-Acoustic Propulsion Laboratory (AAPL) at the NASA Glenn Research Center. This arena is outfitted specifically for conducting fan noise research with the Advanced Noise Control Fan (ANCF) test rig. It features moveable walls with large acoustic wedges (2 by 2 by 1 ft) that create an acoustic environment usable at frequencies as low as 250 Hz. The arena currently uses two dedicated microphone arrays to acquire fan inlet and exhaust far-field acoustic data. It was used successfully in fiscal year 2003 to complete three ANCF tests. It also allowed Glenn to improve the operational efficiency of the four test rigs at AAPL and provided greater flexibility to schedule testing. There were a number of technical challenges to overcome in bringing the new arena to fruition. The foremost challenge was conflicting acoustic requirements of four different rigs. It was simply impossible to construct a static arena anywhere in the facility without intolerably compromising the acoustic test environment of at least one of the test rigs. This problem was overcome by making the wall sections of the new arena movable. Thus, the arena can be reconfigured to meet the operational requirements of any particular rig under test. Other design challenges that were encountered and overcome included structural loads of the large wedges, personnel access requirements, equipment maintenance requirements, and typical time and budget constraints. The new acoustic arena improves operations at the AAPL facility in several significant ways. First, it improves productivity by allowing multiple rigs to operate simultaneously. Second, it improves research data quality by providing a unique test area within the facility that is optimal for conducting fan noise research. Lastly, it reduces labor and equipment costs by eliminating the periodic need to transport the ANCF into and out of the primary AAPL acoustic arena. The investment to design, fabricate, and install the new compact arena in fiscal year 2002 has paid dividends in fiscal year 2003 and will for many years to come. It has provided a dedicated, high-quality acoustic arena to support low-speed fan testing for ANCF while minimizing scheduling impacts and improving operational productivity in the AAPL facility.

Drosophila adults, when placed into a novel open-field arena, initially exhibit an elevated level of activity followed by a reduced stable level of spontaneous activity and spend a majority of time near the arena edge, executing motions along the walls. In order to determine the environmental features that are responsible for the initial high activity and wall-following behavior exhibited during exploration, we examined wild-type and visually impaired mutants in arenas with different vertical surfaces. These experiments support the conclusion that the wall-following behavior of Drosophila is best characterized by a preference for the arena boundary, and not thigmotaxis or centrophobicity. In circular arenas, Drosophila mostly move in trajectories with low turn angles. Since the boundary preference could derive from highly linear trajectories, we further developed a simulation program to model the effects of turn angle on the boundary preference. In an hourglass-shaped arena with convex-angled walls that forced a straight versus wall-following choice, the simulation with constrained turn angles predicted general movement across a central gap, whereas Drosophila tend to follow the wall. Hence, low turn angled movement does not drive the boundary preference. Lastly, visually impaired Drosophila demonstrate a defect in attenuation of the elevated initial activity. Interestingly, the visually impaired w1118 activity decay defect can be rescued by increasing the contrast of the arena's edge, suggesting that the activity decay relies on visual detection of the boundary. The arena boundary is, therefore, a primary object of exploration for Drosophila. PMID:22574279

How do features of dressage arenas influence training surface properties which are potentially associated with lameness?

Results from a previous study indicated that there are specific arena surface characteristics that are associated with an increased likelihood of lameness in dressage horses. It is important to understand what modifiable arena factors lead to these detrimental surface characteristics. The aim of this study was to describe the use of training surfaces and arenas for United Kingdom dressage horses and to investigate any relationships between arena/surface variables and detrimental surface characteristics. Data from a questionnaire returned by 22.5% of all 11,363 registered members of British Dressage were used for the study. Univariate and multivariable logistic regression models were developed with each of the previously identified surface characteristics as dependent variables. Respondents reported that the majority of arenas were privately owned, sized 20 × 40 m and had a sand and rubber surface. The results indicated that wax-coated and sand and rubber surfaces were associated with less detrimental surface properties than sand, sand and PVC, woodchips or grass. Woodchips were most strongly associated with the detrimental characteristic of slipping, and sand with tripping. The findings indicated that any arena surface should have a base, with limestone the recommended surface, and that crushed concrete was best avoided. This information supported previous studies in racehorses that indicated that surface maintenance is essential, especially when many horses are using an arena daily. Problems were less likely if an arena was privately owned. Copyright © 2010. Published by Elsevier Ltd.

The changing role of health-oriented international organizations and nongovernmental organizations.

Apart from governments, there are many other actors active in the health policy arena, including a wide array of international organizations (IOs), public-private partnerships and non-governmental organizations (NGOs) that state as their main mission to improve the health of (low-income) populations of low-income countries. Despite the steady rise in numbers and prominence of NGOs, however, there is lack of empirical knowledge about their functioning in the international policy arena, and most studies focus on the larger organizations. This has also caused a somewhat narrow focus of theoretical studies. Some scholars applied the 'principal-agent' theory to study the origins of IOs, for example, other focus on changing power relations. Most of those studies implicitly assume that IOs, public-private partnerships and large NGOs act as unified and rational actors, ignoring internal fragmentation and external pressure to change directions. We assert that the classic analytical instruments for understanding the shaping and outcome of public policy: ideas, interests and institutions apply well to the study of IOs. As we will show, changing ideas about the proper role of state and non-state actors, changing positions and activities of major stakeholders in the (international) health policy arena, and shifts in political institutions that channel the voice of diverging interests resulted in (and reflected) the changing positions of the health-oriented organizations-and also affect their future outlook.

Female arsonists: key features, psychopathologies, and treatment needs.

PubMed

Gannon, Theresa A

2010-01-01

Female-perpetrated arson is a topic that has received relatively little research attention from either psychiatrists or psychologists. In this review, available research regarding the characteristics, psychopathologies, and current treatment efforts with female arsonists is reviewed. Evaluation of current research with female arsonists suggests that very few researchers have compared female arsonists either to suitable female offender control groups or male arsons. Consequently, clinical knowledge and practice regarding female-perpetrated arson is underdeveloped relative to both other areas of forensic-clinical psychiatry and to knowledge of male arsonists. Suggestions are made for translating current research into arson interventions with female arsonists. Core arenas for future treatment and research provision are also highlighted.

Verb Aspect and the Activation of Event Knowledge

PubMed Central

Ferretti, Todd R.; Kutas, Marta; McRae, Ken

2011-01-01

The authors show that verb aspect influences the activation of event knowledge with 4 novel results. First, common locations of events (e.g., arena) are primed following verbs with imperfective aspect (e.g., was skating) but not verbs with perfect aspect (e.g., had skated). Second, people generate more locative prepositional phrases as completions to sentence fragments with imperfective than those with perfect aspect. Third, the amplitude of the N400 component to location nouns varies as a function of aspect and typicality, being smallest for imperfective sentences with highly expected locations and largest for imperfective sentences with less expected locations. Fourth, the amplitude of a sustained frontal negativity spanning prepositional phrases is larger following perfect than following imperfective aspect. Taken together, these findings suggest a dynamic interplay between event knowledge and the linguistic stream. PMID:17201561

Beyond the Academic Journal: Unfreezing Misconceptions About Mental Illness and Gun Violence Through Knowledge Translation to Decision-Makers.

In a policy arena characterized by polarized debate, such as the consideration of legal interventions to prevent gun violence, research evidence is an important tool to inform decision-making processes. However, unless the evidence is communicated to stakeholders who can influence policy decisions, the research will often remain an academic exercise with little practical impact. The Educational Fund to Stop Violence's process of "unfreezing" individual perceptions and conventional interpretations of the relationship between mental illness and gun violence, forming a consensus, and translating this knowledge to stakeholders through state discussion forums is one way to inform policy change. The recent passage of gun violence prevention legislation in California provides an example of successfully closing the knowledge translation gap between research and decision-making processes.

Being perceived as a 'visitor' in the nursing staff's working arena--the involvement of relatives in daily caring activities in nursing homes in an urban community in Sweden.

2013-09-01

It is both complex and difficult for relatives when a loved one moves into a nursing home and many relatives are not prepared for the realities these new situations entail. Little attention has been paid to scrutinising the involvement of relatives in patient care, particularly in relation to the structures and routines of nursing homes or to the staff's reasoning concerning their involvement. To describe, from a gender perspective, how nursing staff's routines and reasoning act to condition the involvement of relatives in nursing homes. Focused ethnographic fieldwork was conducted in a medium-sized urban community in central Sweden in three different nursing homes. The nursing staff assigns a certain code of conduct to all relatives they perceived as 'visitors' in their working arena. This code of conduct was related to the routines and subcultures existing among the nursing staff and stemmed from a division of labour; the underlying concept of 'visitor' predetermined the potential for relatives' involvement. This involvement is explicitly related to the general gendered characteristics that exist in the nursing staff's perception of the relatives. The study's limitations are primarily concerned with shortcomings associated with a research presence during the fieldwork. The discussion focuses on the dimensions of power structures observed in the nursing home routines and the staff's reasoning based on their gendered assumptions. We argue that it is important to develop mechanisms that provide opportunities for nursing staff in elderly care to reflect on these structures without downplaying the excellent care they provide. We stress the importance of further exploring these issues concerning relatives and their involvement in nursing homes to facilitate the transition from informal caregiver to 'visitor'. © 2012 The Authors Scandinavian Journal of Caring Sciences © 2012 Nordic College of Caring Science.

Novel psychoactive substances (NPS) are new psychotropic drugs, not scheduled under the International Conventions on Psychotropic Substances, but which may pose a relevant public health threat. In this study, we investigated knowledge and use of NPS in a sample of Italian youth in urban and rural areas. Between December 2012 and October 2013, we administered a questionnaire to a sample of 3011 healthy subjects (44.7% men; 55.3% women), aged between 16 and 24 years and recruited in urban, intermediate and rural areas of Italy. Of the global sample, 53.3% declared to have some knowledge on NPS, with a higher knowledge in urban areas. Mephedrone (26%), desomorphine (22.6%) and methamphetamine (21.7%) were the most commonly known drugs. NPS use was reported by 4.7% of the sample, without significant differences between urban and rural areas; mephedrone (3.3%), synthetic cannabinoids (1.2%) and Salvia divinorum (0.3%) consumption has been identified. NPS use was also predictive of binge-drinking behaviours (χ(2) (4) = 929.58, p < .001). Urban areas may represent a focal point for preventive strategies, given the presence of higher levels of NPS knowledge. Moreover, the association between binge-drinking habits and NPS use was really strong. This issue should not be underestimated because of its medical, psychopathological and social consequences.

Gatekeepers in the healthcare sector: Knowledge and Bourdieu's concept of field.

PubMed

Collyer, Fran M; Willis, Karen F; Lewis, Sophie

2017-08-01

Choice is an imperative for patients in the Australian healthcare system. The complexity of this healthcare 'maze', however, means that successfully navigating and making choices depends not only on the decisions of patients, but also other key players in the healthcare sector. Utilising Bourdieu's concepts of capital, habitus and field, we analyse the role of gatekeepers (i.e., those who control access to resources, services and knowledge) in shaping patients' experiences of healthcare, and producing opportunities to enable or constrain their choices. Indepth interviews were conducted with 41 gatekeepers (GPs, specialists, nurses, hospital administrators and policymakers), exploring how they acquire and use knowledge within the healthcare system. Our findings reveal a hierarchy of knowledges and power within the healthcare field which determines the forms of knowledge that are legitimate and can operate as capital within this complex and dynamic arena. As a consequence, forms of knowledge which can operate as capital, are unequally distributed and strategically controlled, ensuring democratic 'reform' remains difficult and 'choices' limited to those beneficial to private medicine.

Opioid use is highly prevalent in the United States and there has been an increased incidence in the rate of opioid-related overdose. While evidence suggests there are substantial differences in opioid use among rural versus urban settings, the rate of overdose and corresponding frequency of opioid overdose risk behaviors and overdose knowledge between rural and urban settings have not been examined. Individuals with opioid use disorder from rural (N=98) and urban (N=247) settings completed a self-report survey regarding their lifetime history of overdose and overdose risk behaviors. Participants also completed the Brief Opioid Overdose Knowledge (BOOK) questionnaire, a 12-item self-report measure of opioid overdose knowledge. Overall, 35.6% of participants had experienced an overdose, and prevalence of overdose was significantly higher (p<.01) among rural (45.9%) vs. urban (31.6%) participants, though fewer rural participants reported past 30-day risk behaviors. There were few differences observed between the subset of rural and urban participants who had experienced an overdose, and fewer rural participants with a history of overdose reported past 30-day risk behaviors. Both rural and urban participants performed poorly on the BOOK, though the percent of correct responses was lowest among rural participants with a history of overdose. Results demonstrate higher rates of overdose among rural opioid users, though rural participants were less likely to report recent risk behaviors. Results also suggest that knowledge regarding key factors related to opioid overdose is severely lacking, particularly among rural opioid users, which could be a potential target for future intervention efforts.

In this research we discuss how soil scientists can help to reach the recently adopted UN Sustainable Development Goals in the most effective manner. Soil science, as a land-related discipline has important links to several of the SDGs which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions. We explore and discuss how soil scientists can rise to the challenge both internally, in terms of our procedures and practices, and externally in terms of our relations with colleague scientists in other disciplines, diverse groups of stakeholders and the policy arena. To meet these goals we recommend the following steps to be taken by the soil science community as a whole: (i) Embrace the UN Sustainable Development Goals, as they provide a platform that allows soil science to demonstrate its relevance for realizing a sustainable society by 2030; (ii) Show the specific value of soil science: Research should explicitly show how using modern soil information can improve the results of inter- and trans-disciplinary studies on SDGs related to food security, water scarcity, climate change, biodiversity loss and health threats; (iii) Given the integrative nature of soils, soil scientists are in a unique position to take leadership in overarching systems-analyses of ecosystems; (iii) Raise awareness of soil organic matter as a key attribute of soils to illustrate its importance for soil functions and ecosystem services; (iv) Improve the transfer of knowledge through knowledge brokers with a soil background; (v) Start at the basis: educational programs are needed at all levels, starting in primary schools, and emphasizing practical, down-to-earth examples; (vi) Facilitate communication with the policy arena by framing research in terms that resonate with politicians in terms of the policy cycle or by considering drivers, pressures and responses affecting impacts of land use change; and finally (vii) All this is only possible if researchers, with soil scientists in the frontlines, look over the hedge towards other disciplines, to the world-at-large and to the policy arena, reaching over to listen first, as a basis for genuine collaboration.

In this forum paper we discuss how soil scientists can help to reach the recently adopted UN Sustainable Development Goals (SDGs) in the most effective manner. Soil science, as a land-related discipline, has important links to several of the SDGs, which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions (see graphical abstract in the Supplement). We explore and discuss how soil scientists can rise to the challenge both internally, in terms of our procedures and practices, and externally, in terms of our relations with colleague scientists in other disciplines, diverse groups of stakeholders and the policy arena. To meet these goals we recommend the following steps to be taken by the soil science community as a whole: (i) embrace the UN SDGs, as they provide a platform that allows soil science to demonstrate its relevance for realizing a sustainable society by 2030; (ii) show the specific value of soil science: research should explicitly show how using modern soil information can improve the results of inter- and transdisciplinary studies on SDGs related to food security, water scarcity, climate change, biodiversity loss and health threats; (iii) take leadership in overarching system analysis of ecosystems, as soils and soil scientists have an integrated nature and this places soil scientists in a unique position; (iii) raise awareness of soil organic matter as a key attribute of soils to illustrate its importance for soil functions and ecosystem services; (iv) improve the transfer of knowledge through knowledge brokers with a soil background; (v) start at the basis: educational programmes are needed at all levels, starting in primary schools, and emphasizing practical, down-to-earth examples; (vi) facilitate communication with the policy arena by framing research in terms that resonate with politicians in terms of the policy cycle or by considering drivers, pressures and responses affecting impacts of land use change; and finally (vii) all this is only possible if researchers, with soil scientists in the front lines, look over the hedge towards other disciplines, to the world at large and to the policy arena, reaching over to listen first, as a basis for genuine collaboration.

Academic faculty involved in public health teaching and research serve as the link and catalyst for knowledge synthesis and exchange, enabling the flow of information resources, and nurturing relations between 'two distinct communities' - researchers and policymakers - who would not otherwise have the opportunity to interact. Their role and their characteristics are of particular interest, therefore, in the health research, policy and practice arena, particularly in low- and middle-income countries. We investigated the individual attributes, capacities and skills of academic faculty identified as knowledge brokers (KBs) in schools of public health (SPH) in Kenya with a view to informing organisational policies around the recruitment, retention and development of faculty KBs. During April 2013, we interviewed 12 academics and faculty leadership (including those who had previously been identified as KBs) from six SPHs in Kenya, and 11 national health policymakers with whom they interact. Data were qualitatively analyzed using inductive thematic analysis to unveil key characteristics. Key characteristics of KBs fell into five categories: sociodemographics, professional competence, experiential knowledge, interactive skills and personal disposition. KBs' reputations benefitted from their professional qualifications and content expertise. Practical knowledge in policy-relevant situations, and the related professional networks, allowed KB's to navigate both the academic and policy arenas and also to leverage the necessary connections required for policy influence. Attributes, such as respect and a social conscience, were also important KB characteristics. Several changes in Kenya are likely to compel academics to engage increasingly with policymakers at an enhanced level of debate, deliberation and discussion in the future. By recognising existing KBs, supporting the emergence of potential KBs, and systematically hiring faculty with KB-specific characteristics, SPHs can enhance their collective human capital and influence on public health policy and practice. Capacity strengthening of tangible skills and recognition of less tangible personality characteristics could contribute to enhanced academic-policymaker networks. These, in turn, could contribute to the relevance of SPH research and teaching programs as well as evidence-informed public health policies.

How does the World Trade Organization know? The mobilization and staging of scientific expertise in the GMO trade dispute.

PubMed

Bonneuil, Christophe; Levidow, Les

2012-02-01

The World Trade Organization (WTO) dispute settlement procedure is a key arena for establishing global legal norms for what counts as relevant knowledge. As a high-profile case, the WTO trade dispute on GMOs mobilized scientific expertise in somewhat novel ways. Early on, the Panel put the dispute under the Sanitary and Phytosanitary (SPS) Agreement through a new legal ontology; it classified transgenes as potential pests and limited all environmental issues to the 'plant and animal health' category. The selection of scientific experts sought a multi-party consensus through a fast adversarial process, reflecting a specific legal epistemology. For the SPS framing, focusing on the defendant's regulatory procedures, the Panel staged scientific expertise in specific ways that set up how experts were questioned, the answers they would give, their specific role in the legal arena, and the way their statements would complement the Panel's findings. In these ways, the dispute settlement procedure co-produced legal and scientific expertise within the Panel's SPS framework. Moreover, the Panel operated a procedural turn in WTO jurisprudence by representing its findings as a purely legal-administrative judgement on whether the EC's regulatory procedures violated the SPS Agreement, while keeping implicit its own judgements on substantive risk issues. As this case illustrates, the WTO settlement procedure mobilizes scientific expertise for sophisticated, multiple aims: it recruits a source of credibility from the scientific arena, thus reinforcing the standard narrative of 'science-based trade discipline', while also constructing new scientific expertise for the main task--namely, challenging trade restrictions for being unduly cautious.

Scientists working on ecosystem service (ES) science are engaged in a mission-driven discipline. They can contribute to science-policy interfaces where knowledge is co-produced and used. How scientists engage with the governance arena to mobilise their knowledge remains a matter of personal choice, influenced by individual values. ES science cannot be considered neutral and a discussion of the values that shape it forms an important part of the sustainability dialogue. We propose a simple decision tree to help ES scientists identify their role and the purpose of the knowledge they produce. We characterise six idealised scientific postures spanning possible roles at the science-policy interface (pure scientist, science arbiter-guarantor, issue advocate-guardian, officer, honest broker and stealth issue advocate) and illustrate them with feedbacks from interviews. We encourage ES scientists to conduct a reflexive exploration of their attitudes regarding knowledge production and use, with the intention of progressing toward a higher recognition of the political and ethical importance of ES assessments.

Length of residence, age and patterns of medicinal plant knowledge and use among women in the urban Amazon

PubMed Central

2014-01-01

Background This paper explores patterns of women’s medicinal plant knowledge and use in an urban area of the Brazilian Amazon. Specifically, this paper examines the relationship between a woman’s age and her use and knowledge of medicinal plants. It also examines whether length of residence in three different areas of the Amazon is correlated with a woman’s use and knowledge of medicinal plants. Two of the areas where respondents may have resided, the jungle/seringal and farms/colonias, are classified as rural. The third area (which all of the respondents resided in) was urban. Methods This paper utilizes survey data collected in Rio Branco, Brazil. Researchers administered the survey to 153 households in the community of Bairro da Luz (a pseudonym). The survey collected data on phytotherapeutic knowledge, general phytotherapeutic practice, recent phytotherapeutic practice and demographic information on age and length of residence in the seringal, on a colonia, and in a city. Bivariate correlation coefficients were calculated to assess the inter-relationships among the key variables. Three dependent variables, two measuring general phytotherapeutic practice and one measuring phytotherapeutic knowledge were regressed on the demographic factors. Results The results demonstrate a relationship between a woman’s age and medicinal plant use, but not between age and plant knowledge. Additionally, length of residence in an urban area and on a colonia/farm are not related to medicinal plant knowledge or use. However, length of residence in the seringal/jungle is positively correlated with both medicinal plant knowledge and use. Conclusions The results reveal a vibrant tradition of medicinal plant use in Bairro da Luz. They also indicate that when it comes to place of residence and phytotherapy the meaningful distinction is not rural versus urban, it is seringal versus other locations. Finally, the results suggest that phytotherapeutic knowledge and use should be measured separately since one may not be an accurate proxy for the other. PMID:24565037

Although urban community gardening can offer health, social, environmental, and economic benefits, these benefits must be weighed against the potential health risks stemming from exposure to contaminants such as heavy metals and organic chemicals that may be present in urban soils. Individuals who garden at or eat food grown in contaminated urban garden sites may be at risk of exposure to such contaminants. Gardeners may be unaware of these risks and how to manage them. We used a mixed quantitative/qualitative research approach to characterize urban community gardeners' knowledge and perceptions of risks related to soil contaminant exposure. We conducted surveys with 70 gardeners from 15 community gardens in Baltimore, Maryland, and semi-structured interviews with 18 key informants knowledgeable about community gardening and soil contamination in Baltimore. We identified a range of factors, challenges, and needs related to Baltimore community gardeners' perceptions of risk related to soil contamination, including low levels of concern and inconsistent levels of knowledge about heavy metal and organic chemical contaminants, barriers to investigating a garden site's history and conducting soil tests, limited knowledge of best practices for reducing exposure, and a need for clear and concise information on how best to prevent and manage soil contamination. Key informants discussed various strategies for developing and disseminating educational materials to gardeners. For some challenges, such as barriers to conducting site history and soil tests, some informants recommended city-wide interventions that bypass the need for gardener knowledge altogether.

Environmental health literacy (EHL) is a promising and evolving field of research that could benefit from youth engagement. Yet studies focused on youths' environmental health awareness and concerns are limited. For example, although lead exposure remains a threat to youth development in urban environments, no published studies have measured urban youth's knowledge of lead poisoning. A CBPR partnership established a youth advisory council (YAC) who helped to design, interpret and disseminate a mixed methods study exploring environmental health perceptions among urban youths ages 10-18. Surveys assessed awareness, attitudes, and knowledge regarding lead poisoning and five environmental health issues determined by the YAC. Focus group questions further contextualized youths' lead knowledge and understanding of youths' environmental health concerns. A majority of youth could identify specific sources of lead exposure but had minimal knowledge of prevention strategies, and focus group data revealed misinformation regarding lead sources and consequences. Survey and focus group respondents' level of awareness and concern regarding YAC-selected EH issues was high in comparison to lead poisoning. In particular, job opportunities and police brutality were endorsed as both neighborhood concerns and priorities. Awareness and knowledge of environmental health issues among urban youth have not been well described. These findings reinforce the importance of addressing problems of local relevance. Moving forward, lead poisoning prevention education for youth and youth EHL partnerships may benefit from incorporating an ecological approach wherein connections to the social and economic context are made explicit.

In much of the world cities are warming at twice the rate of outlying rural areas. The frequency of urban heat waves is projected to increase with climate change through the 21st century. Addressing the economic, environmental, and human costs of urban heat islands requires a better understanding of their behavior from many disciplinary perspectives. The goal of this four-year Urban Heat Island Network is to (1) bring together scientists studying the causes and impacts of urban warming, (2) advance multidisciplinary understanding of urban heat islands, (3) examine how they can be ameliorated through engineering and design practices, and (4) share these new insights with a wide array of stakeholders responsible for managing urban warming to reduce their health, economic, and environmental impacts. The NSF-RCN Urban Heat Island Network involves atmospheric scientists, engineers, architects, landscape designers, urban planners, public health experts, and education and outreach experts, who will share knowledge, evaluate research directions, and communicate knowledge and research recommendations to the larger research community as well as stakeholders engaged in developing strategies to adapt to and mitigate urban warming. The first Urban Climate Institute was held in Saint Paul, MN in July 2013 and focused on the characteristics of urban heat islands. Scientists engaged with local practitioners to improve communication pathways surrounding issues of understanding, adapting to, and mitigating urban warming. The second Urban Climate Institute was held in Atlanta, Georgia in July 2014 and focused on urban warming and public health. The third Urban Climate Institute was held in Athens, GA in July 2015 and focused on urban warming and the role of the built environment. Scientists and practitioners discussed strategies for mitigation and adaptation. The fourth Institute was held in Saint Paul, MN in July 2016 and focused on putting research to practice. Evaluation experts at the Science Museum of Minnesota have extensively evaluated the Institutes to inform other research coordination networks and to identify effective ways that researchers and practitioners can share knowledge and communicate more effectively.

Urban conservation education programs aim to increase knowledge and awareness towards biodiversity and to change attitudes and behaviour towards the environment. However, to date, few urban conservation education studies have evaluated to what extent these programs have managed to achieve their goals. In this study, we experimentally explored the influence of an urban conservation activity day on individual knowledge, awareness and actions towards biodiversity, in both the short and longer term.We organised three activity days in Paris (France), during which people were invited to participate in urban conservation efforts. Both quantitative (questionnaire) and qualitative (interviews) methods were employed to investigate the influence of this short urban nature experience on the relationships that city-dwellers develop with nearby biodiversity. We found a strong positive correlation between the levels of participation and an immediate interest towards local urban biodiversity. In the longer term, however, although participants claimed to have gained more knowledge, local awareness and interest for species in their daily environment, they did not seem to extend this interest to participating in other related activities. These results highlight the complexity of validating the effectiveness of this type of education program for achieving conservation goals. Although such a short activity may only have a limited environmental impact, it nevertheless seems to increase people's knowledge, awareness, interest and concern. We therefore believe that when repeated locally, these short conservation education programs could enhance people's experience with nature in cities and achieve conservation goals more fully.

Rural emergency departments (EDs) generally have limited access to continuing education and are typically staffed by clinicians without pediatric emergency specialty training. Emergency care of children is complex and the majority of children receive emergency care in non-pediatric tertiary care centers. In recent decades, there has been a call to action to improve quality and safety in the emergency care of children. Of the one million ED visits by children in Ontario in 2005-2006, one in three visited more than once in a year and one in 15 returned to the ED within 72 hours of the index visit. This study explored factors influencing rural and urban ED clinicians' participation in a Web-based knowledge exchange intervention that focused on best practice knowledge about pediatric emergency care. The following questions guided the study: (i) What are the individual, context of practice or knowledge factors which impact a clinician's decision to participate in a Web-based knowledge exchange intervention?; (ii) What are clinicians' perceptions of organizational expectations regarding knowledge and information sources to be used in practice?; and (iii) What are the preferred knowledge sources of rural and urban emergency clinicians? A Web-based knowledge exchange intervention, the Pediatric Emergency Care Web Based Knowledge Exchange Project, for rural and urban ED clinicians was developed. The website contained 12 pediatric emergency practice learning modules with linked asynchronous discussion forums. The topics for the modules were determined through a needs assessment and the module content was developed by known experts in the field. A follow-up survey was sent to a convenience sample of 187 clinicians from nine rural and two urban Canadian EDs participating in the pediatric emergency Web-based knowledge exchange intervention study. The survey response rate was 56% (105/187). Participation in the knowledge exchange intervention was related to individual involvement in research activities (χ(2)=5.23, p=0.019), consultation with colleagues from other EDs (χ(2)=6.37, p=0.01) and perception of organizational expectations to use research evidence to guide practice (χ(2)=5.52, p=0.015). Most clinicians (95/105 or 92%) reported relying on colleagues from their own ED as a primary knowledge source. Urban clinicians were more likely than their rural counterparts to perceive that use of research evidence to guide practice was an expectation. Rural clinicians were more likely to rely on physicians from their own ED as a preferred knowledge source. The decision made by emergency clinicians to participate in a Web-based knowledge exchange intervention was influenced by a number of individual and contextual factors. Differences in these factors and preferences for knowledge sources require further characterization to enhance engagement of rural ED clinicians in online knowledge exchange interventions.

The objective of this study was to assess the level of knowledge of cervical cancer among Bangladeshi women and to assess their willingness to receive the human papillomavirus (HPV) vaccine. A population-based, cross-sectional survey was conducted from July to December 2011 in one urban and one rural area of Bangladesh. A total of 2037 ever-married women, aged 14 to 64 years, were interviewed using a structured questionnaire. Data on socio-demographic characteristics and knowledge of cervical cancer were collected. Willingness to receive the HPV vaccine was assessed. Univariate analyses were completed using quantitative data collected. Multivariable logistic regression models were developed to identify factors associated with having heard of cervical cancer and the HPV vaccine. The majority of study participants reported to have heard of cervical cancer (urban: 89.7%, rural 93.4%; P = 0.003). The odds of having heard of cervical cancer were significantly higher in urban women aged 35-44 years (aOR: 2.92 (1.34-6.33) and rural women aged 25-34 years (aOR: 2.90 (1.24-6.73) compared to those aged less than 24 years. Very few women reported to have detailed knowledge on risk factors (urban:9.1%, rural: 8.8%) and prevention (urban: 6.4%, rural: 4.4%) of cervical cancer. In our sample, one in five urban women and one in twenty rural women heard about a vaccine that can prevent cervical cancer. Among urban women, secondary education or higher (aOR: 3.48, 95% CI: 1.67-7.25), age of 20 years and above at marriage (aOR: 2.83, 95% CI: 1.61-5.00), and high socioeconomic status (aOR: 2.25, 95% CI: 1.28-3.95) were factors associated with having heard of the HPV vaccine. Willingness to receive the HPV vaccine among study participants either for themselves (urban: 93.9%, rural: 99.4%) or for their daughters (urban: 91.8%, rural: 99.2%) was high. Detailed knowledge of cervical cancer among Bangladeshi women was found to be poor. Education on cervical cancer must include information on symptoms, risk factors, and preventive methods. Despite poor knowledge, the study population was willing to receive the HPV vaccine.

Exploratory activity and habituation of Drosophila in confined domains

NASA Astrophysics Data System (ADS)

Soibam, B.; Chen, L.; Roman, G. W.; Gunaratne, G. H.

2014-09-01

Animals use locomotion to find food, shelter, and escape routes as well as to locate predators, competitors, and mates. Thus, locomotion is related to many behavioral traits, and can be used to characterize these more complex facets of behavior. Exploratory behaviors are random and need to be assessed through stochastic analysis. By comparing ensembles of trajectories from Drosophila and a model animal, we identify a pair of principles that govern the stochastic motion of a specific species. The first depends on local cues and quantify directional persistence, i.e., the propensity of an animal to maintain direction; the second, its attraction to walls, is relevant for exploration in confined arenas. Statistical properties of exploratory activity in several types of arenas can be computed from these principles. A pair of spiral arenas are designed to demonstrate that centrophobicity, or fear of the center of an arena, is not a fundamental feature of exploration. xxxx We provide evidence to show that the decay in an animal's activity following its introduction into a novel arena is correlated to its familiarity with the arena. We define two measures, coverage and habituation, to quantify familiarity. It is found that the relationship between activity and coverage is independent of the arena size. Finally, we use an analysis of exploration of mutant species to infer that in Drosophila, habituation relies on visual cues.

Knowledge and attitudes toward organ donation: a community-based study comparing rural and urban populations.

2010-01-01

The study was set to determine whether knowledge and attitudes toward organ donation differ according to geographical location. Self-administered questionnaires were employed to collect data such as demographic characteristics, basic knowledge, attitudes and source of information about organ donation from subjects in rural and urban areas. The questionnaires were distributed randomly to 1,000 individuals in both areas during 2008. The data were analyzed in a descriptive fashion. Despite similarities in knowledge and attitudes of respondents in both areas, rural respondents were less likely to have information about organ donation, to report willingness to donate organs, and to have knowledge about "brain death" or the "organ donation card" than their counterparts in urban areas. The study identified that the principle respondents' source of information about organ donation was the television. More than 90% of respondents in rural and urban areas reported that the contribution of health care providers in providing them with knowledge about organ donation and transplantation was "none" or "little". Respondents identified several reasons, which may influence their decisions to donate organs. In conclusion, the deficit in knowledge and attitudes of rural respondents about organ donation may be justified by the lack of information about this significant issue. Accordingly, health facilities, local mass media and educational institutions should provide intensive educational programs to encourage the public donate organs.

Older adults are more likely to experience problems that contribute to an increase in burn-related morbidity and mortality. The purpose of the current study was to determine if the educational home fire safety (HFS) intervention was an effective method of improving HFS knowledge over time in two groups of urban older adults, home bound and community-based. HFS knowledge of 110 urban older adults was assessed at baseline, immediately after watching a HFS DVD (recall), and at 2-week follow-up (retention). The United States Fire Administration Home Safety Checklist which examines HFS practices in the home was also administered. HFS knowledge scores significantly increased over time for both groups (p<0.0001), but no significant differences existed between the two groups over time (p=0.183). In addition, HFS knowledge scores were significantly impacted by the number of chronic illnesses, number of independent activities of daily living, and income. The findings from this study suggest the educational HFS intervention was effective in increasing urban older adults' HFS knowledge over time. Lowering the burns morbidity and mortality in the older adult population is an important public health concern that needs to be addressed through tailored prevention and education strategies.

A recent epidemiological study identified various aspects of arena surfaces and arena surface maintenance that were related to risk of injury in horses and that arena maintenance is important in reducing injury risk. However, there has been little research into how properties of arena surfaces change with harrowing. This study aimed to compare the properties of different arena surface types pre- and post-harrowing. The Orono Biomechanical Surface Tester fitted with accelerometers and a single- and a three-axis load cell was used to test 11 arenas with two different surfaces types, sand with rubber (SR) and waxed-sand with fibre (WSF). Three drop tests were carried out at 10 standardised locations on each arena. Mixed models were created to assess the effect of surface type, pre- or post-harrowing, and drop number on the properties of the surface, including maximum horizontal deceleration, maximum vertical deceleration, maximum vertical load and maximum horizontal load. Post-harrowing, none of the parameters were altered significantly on SR. On WSF, maximum vertical deceleration and maximum vertical load significantly decreased post-harrowing. The differences in the effects of superficial harrowing on SR and WSF could be attributed to the different compositions and sizes of the surface material. The results suggest that different maintenance techniques may be more suitable for different surface types and that the effects of superficial harrowing are short-lived due to the rapid re-compaction of the surface with repeated drops on WSF. Further work is required to determine the effects of other maintenance techniques, and on other surface types. Copyright © 2014 Elsevier Ltd. All rights reserved.

2016-01-01

Adolescence is an important phase of life with increasing independence and identity development, and a vulnerable period of life for chronically ill adolescents with a high occurrence of insufficient treatment adherence. We conducted four photo elicitation focus group interviews with 14 adolescents (12-20 years) with juvenile idiopathic arthritis to investigate identity constructions during transition. Using a discourse analysis approach, six identity types were identified distributed on normal and marginal identities, which were lived either at home (home arena) or outside home with peers (out arena). Most participants positioned themselves as normal in the out arena and as ill in the home arena. Few participants positioned themselves as ill in an out arena, and they described how peers perceived this as a marginal and skewed behavior. This study contributes to a better understanding of why it can be extremely difficult to live with a chronic illness during adolescence. PMID:28462329

Assessment of epidemiological situation in the Middle East, in the Mediterranean Sea basin, based on the status of the Syrian health service and diseases occurring among society of this country within the space of the last tens of years is presented in this article. Knowledge of morbidity and morbidness of Syrians, representatives of Arab-Muslim community is relatively low. First of all, it is related to isolation of Syria in the international arena, poor status of education and health service, lack of current epidemiological data on health condition of the country population. Knowledge of issues mentioned above has essential importance for people working or serving in Syria (military and civilian UN personnel), as well as for tourists travelling in the Middle East.

Bannier, Betsy J.

2010-06-01

While comprehensive texts, articles, and literature reviews presenting research in the singular arenas of motivation, help-seeking, and online science learning are relatively easy to find, syntheses and interactions between these constructs are lacking. Part I of this review addresses this knowledge gap by drawing together key research from the domains of educational psychology and adult education, addressing the constructs of motivation, self-efficacy, adult learning, and help-seeking. Part II of this review extends and applies the motivation and help-seeking discussion to the emerging and exciting field of online chemistry education. The result is a comprehensive synthesis of the strengths and limitations of the currently existing body of knowledge related to the motivation and help-seeking behaviors of adult, online chemistry students.

Each weekend soccer arenas attract hundreds of thousands of spectators with the German Bundesliga being one of the most attractive sport series worldwide. In 2006 when the FIFA soccer World Cup™ took place in Germany, the precautions in the participating arenas against mass casualty incidents (MCI) reached a level formerly unknown in Germany. However, it is unknown how soccer arenas are prepared to deal with such incidents in everyday life. In 2011 all German major soccer league clubs were questioned about medical precautions in case of MCIs occurring in the stadium. The questionnaire included the following items: stadium capacity, the number of paramedic personnel, emergency physicians and ambulance vehicles, the command and communication structures, the availability of MCI plans, recent MCI drills and the frequency of MCI. Out of 39, 15 (38.4 %) participated, 50 % from the first league and 20.8 % from the second league. The mean stadium capacity was 41,800 spectators (minimum 10,600, maximum 80,700). Depending on the number of spectators and the individual risk score of the match the following resources were available within the stadiums (average, minimum, maximum,): emergency medical technicians 61-67 (15, 120), emergency physicians 2.3-2.5 (1, 5) and transport capacity 5.3-5.8 patients (1, 15). In 14 arenas (93.3 %) the medical personnel were trained in mass casualty care and had prepared MCI operation schedules. All stadiums had mission control centers equipped with a variety of wired and wireless communication tools, although only eight (52.3 %) arenas used a joint command structure and five (33.3 %) arenas reported MCIs (defined as a scenario involving more than 10 patients) within the past 10 years. In 40 % of the participants the last MCI-related exercise was conducted more than 36 months ago. Most of the participating arenas were adequately staffed to manage the first phase of MCIs but in contrast command structures and transport capacities often focused on individual emergencies. Although most of the participants stated that they planned the resources provision according to well established algorithms, the resources actually available at the arenas varied considerably. The frequency of MCIs in soccer arenas was surprisingly high in contrast to the frequency of MCI-related drills.

Connecting Urban Youth with their Environment: The Impact of an Urban Ecology Course on Student Content Knowledge, Environmental Attitudes and Responsible Behaviors

Hashimoto-Martell, Erin A.; McNeill, Katherine L.; Hoffman, Emily M.

2012-10-01

This study explores the impact of an urban ecology program on participating middle school students' understanding of science and pro-environmental attitudes and behaviors. We gathered pre and post survey data from four classes and found significant gains in scientific knowledge, but no significant changes in student beliefs regarding the environment. We interviewed 12 students to better understand their beliefs. Although student responses showed they had learned discrete content knowledge, they lacked any ecological understanding of the environment and had mixed perceptions of the course's relevance in their lives. Students reported doing pro-environmental behaviors, but overwhelmingly contributed such actions to influences other than the urban ecology course. Analyses indicated a disconnect between the course, the environment, and the impact on the students' lives. Consequently, this suggests the importance of recognizing the implications of context, culture, and identity development of urban youth. Perhaps by providing explicit connections and skills in urban environmental programs through engaging students in environmental scientific investigations that stem from their own issues and questions can increase student engagement, motivation, and self-efficacy of environmental issues.

Monitoring the Urban Tree Cover for Urban Ecosystem Services - The Case of Leipzig, Germany

Banzhaf, E.; Kollai, H.

2015-04-01

Urban dynamics such as (extreme) growth and shrinkage bring about fundamental challenges for urban land use and related changes. In order to achieve a sustainable urban development, it is crucial to monitor urban green infrastructure at microscale level as it provides various urban ecosystem services in neighbourhoods, supporting quality of life and environmental health. We monitor urban trees by means of a multiple data set to get a detailed knowledge on its distribution and change over a decade for the entire city. We have digital orthophotos, a digital elevation model and a digital surface model. The refined knowledge on the absolute height above ground helps to differentiate tree tops. Grounded on an object-based image analysis scheme a detailed mapping of trees in an urbanized environment is processed. Results show high accuracy of tree detection and avoidance of misclassification due to shadows. The study area is the City of Leipzig, Germany. One of the leading German cities, it is home to contiguous community allotments that characterize the configuration of the city. Leipzig has one of the most well-preserved floodplain forests in Europe.

Development of professional knowledge in action: experiences from an action science design focusing on acknowledging communication in mental health.

Vatne, Solfrid; Bjornerem, Heidi; Hoem, Elisabeth

2009-03-01

This article reports a multi-professional development project that was based on an action science design. The purpose was to develop 'acknowledging communication' in a psychiatric department for young people, and the objective to study the staffs' experiences of participating in the project. The professional part of the project has its foundation in Schibbye's treatment theory of inter-subjective understanding of relationships, and involves three main approaches from her theory: self-reflection, self-delimitation and emotional presence. The article presents the specific action design used, where reflection processes were developed in three different arenas: multidisciplinary Reflection groups, a Leader support group for the group leaders of the Reflection groups and collective Project seminars for all employees. A formal study programme designed to increase professional expertise, 15 European Credit Transfer System (ECTS), was also offered. The research methods included the researcher's process notes taken during the process, field notes from participating in the Leader support group, and qualitative interviews of eight informants participating in the various reflection arenas. The article presents and discusses the experiences evolved from the methods that were developed during the professional action science project: reflection on specific situations of interaction with patients in the form of oral/written narratives and the development of video presentations in combination with 'reflective teams'. The study showed that to facilitate change in the role of staff members, it is important to combine several reflection arenas where theoretical principles can be converted into practical action. By drawing data from only one study site, the study has a limited transferability, but should be of interest for professionals working with clinical change processes.

Emergency contraception. General practitioner knowledge, attitudes and practices in New South Wales.

1995-02-06

To assess the knowledge, attitudes and practices of general practitioners in New South Wales regarding the provision of emergency contraception. Randomised group comparison of 100 rural and 100 urban general practitioners (GPs) by questionnaire. Eighty-four rural and 76 urban GPs responded. More rural GPs were knowledgeable about emergency contraception than urban GPs (95% v. 78%), and more women knew about it than men. More urban GPs frequently prescribed emergency contraception than rural GPs (26% v. 6%) and female GPs prescribed it more readily than male GPs (22% v. 12%). There was great variation in the regimens prescribed, especially among rural GPs. Twenty-five per cent of urban GPs and 31% of rural GPs did not offer women information about emergency contraception, while 16% of both groups included such information in any discussion about contraceptive options, and 18% gave information only if requested by the woman. More than 60% of the GPs would provide information about emergency contraception as a back-up to use of barrier methods. The sex, attitude and knowledge of the GPs influence the likelihood of women being made aware of or being given emergency contraception in NSW. There is a need to further educate both the public and practitioners about emergency contraception.

In much of the world cities are warming at twice the rate of outlying rural areas. The frequency of urban heat waves is projected to increase with climate change through the 21st century. Addressing the economic, environmental, and human costs of urban heat islands requires a better understanding of their behavior from many disciplinary perspectives. The goal of this four-year Urban Heat Island Network is to (1) bring together scientists studying the causes and impacts of urban warming, (2) advance multidisciplinary understanding of urban heat islands, (3) examine how they can be ameliorated through engineering and design practices, and (4) share these new insights with a wide array of stakeholders responsible for managing urban warming to reduce their health, economic, and environmental impacts. The NSF-RCN Urban Heat Island Network involves atmospheric scientists, engineers, architects, landscape designers, urban planners, public health experts, and education and outreach experts, who will share knowledge, evaluate research directions, and communicate knowledge and research recommendations to the larger research community as well as stakeholders engaged in developing strategies to adapt to and mitigate urban warming. The first Urban Climate Institute was held in Saint Paul, MN in July 2013 and focused on the characteristics of urban heat islands. Scientists engaged with local practitioners to improve communication pathways surrounding issues of understanding, adapting to, and mitigating urban warming. The second Urban Climate Institute was held in Atlanta, Georgia in July 2014 and focused on urban warming and public health. The third Urban Climate Institute was held in Athens, GA in July 2015 and focused on urban warming and the role of the built environment. Scientists and practitioners discussed strategies for mitigation and adaptation. Evaluation experts at the Science Museum of Minnesota have extensively evaluated the Institutes to inform other research coordination networks and to identify effective ways that researchers and practitioners can share knowledge and communicate more effectively. A final Institute is planned for July of 2016 in Saint Paul, MN. This institute will focus on synthesizing findings from the first three workshops and discuss education and outreach efforts.

Can Biogeochemists Help To Enhance Urban Resilience?

NASA Astrophysics Data System (ADS)

Baker, L. A.

2012-12-01

Throughout history, many human settlements have collapsed, often caused or triggered by extreme climatic fluctuation, resource depletion, or pollution. In today's world, with rapid urbanization, much of it in "informal" peri-urban settlements, increasing per capita wealth and consumption, climate warming, and widespread pollution, the potential for collapse of modern cities is a realistic hazard. This presentation addresses the question: can biogeochemists contribute knowledge, and translate that knowledge, into greater resilience of urban systems? I argue that we can, and present four examples, each illustrated with case studies. The first is an example of resource depletion - the eventual exhaustion of P rock used for fertilizer. Phosphate rock reserves are limited, at least in the U.S., causing us to import fertilizer P. Prices are rising, prompting more efficient use. Over the long term, depletion of phosphate rock globally may lead to a "brown devolution". We have started a process of tracking P from agricultural watersheds to the "urban plate", and the potential for recycling urban wastes back to agriculture. Early findings in our lab show that agricultural P use in a high-production watershed is now quite efficient, but urban P use is extremely inefficient. A P balance of the Minneapolis-St. Paul region showed that only 4% of input P was recycled, but 75% recycling was possible, even with off-the-shelf technologies. Recycling urban P to agricultural systems, at least for cities in agricultural regions, could close the P cycle and add resilience to the urban food system. A second example is the loss of resilience caused by pollution. Cities often pollute their groundwater, especially with nitrate, salts, and bacteria, limiting the potential for using underlying aquifers for water supply during drought periods and reducing the resilience of the urban system. This is a serious problem in cities in the developing world that do not have water-based waste removal systems. Better biogeochemical knowledge of urban nutrient flows - and perhaps development of mitigation strategies, such as wetland treatment systems- could help prevent degradation of urban aquifers or restore them, increasing resilience of cities to drought. Third, we know little about how extreme climatic fluctuations alter biogeochemical cycles and how these alterations might affect resilience of cities. The current drought, for example, has had profound effects on lake ecosystems in the Twin Cities. Some of these effects may be semi-permanent, such as "switching" of shallow lakes from macrophyte dominated to algae dominated systems with substantial reduction in human utilization. Finally, simply acquiring biogeochemical knowledge is not sufficient to develop urban resilience. This knowledge needs to be translated into meaningful measurements (to provide feedback) and appropriate responses. Urban biogeochemists need to be involved in translational activities, but cannot do this on an ad hoc basis. Instead, universities need to develop new models to support translational research for urban ecosystems.

Natural flora and anticancer regime: milestones and roadmap.

Cancer has long been an area of extensive research both at the molecular as well as pharmaceutical level. However, lack of understanding of the underlying molecular signalling and the probable targets of therapeutics is a major concern in successful treatment of cancer. The situation becomes even worse, with the increasing side effects of the existing synthetic commercial drugs. Natural compounds especially those derived from plants have been best explored for their anticancer properties and most of them have been efficient against the known molecular targets of cancer. However, advent of biotechnology and resulting advances in medical arena have let to the increasing knowledge of newer carcinogenic signaling agents which has made the anticancer drug discovery even more demanding. The present review aims to bring forward the molecular mediators of cancer and compiles the plant derived anticancer agents with special emphasis on their clinical status. Since marine arena has proved to be a tremendous source of pharmaceutical agents, this review also focuses on the anticancer potential of marine plants especially algae. This is a comprehensive review covering major aspects of cancer mediation and utilization of marine flora for remediation of this deadly disease.

Prenatal care services in the public and private arena.

Blackwell, Deborah A

2002-12-01

This exploratory study described the prenatal care experience in the public and private arena from the perceptions of childbearing women using interpretive interactionism. A face-to-face interview comprised of eight open-ended questions was used to obtain pregnant women's perceptions of their prenatal care experience and prenatal care needs. The purposive sample consisted of six women who received private prenatal care and 14 women who received public prenatal care. Five essential elements of the prenatal care experience were identified. Prenatal care was viewed as a cooperative effort between informal self-care and formal care by health professionals. Issues related to individuality and normality were important considerations in the delivery of prenatal care. Controversy exists over the effectiveness of prenatal care in preventing poor outcomes, as the definition of what constitutes adequate prenatal care remains unclear. Advanced practice nurses (APNs) continue to play a pivotal role in the provision of prenatal care services. The expanded knowledge and skills possessed by APNs place them in a pivotal position to develop and implement individualized, developmentally appropriate prenatal care that the women in this study so desperately wanted. In addition, they can assist women in continuing the health promoting behaviors initiated prenatally through out their lifespan.

Adequate community knowledge about malaria is crucial in order to improve prevention by reducing exposure to the disease. Malaria is a major cause of morbidity and mortality among children of less than five years of age in Equatorial Guinea. However, information concerning the accuracy of community knowledge is insufficient. This study aimed at assessing the depth of caregivers' knowledge of malaria, their beliefs and attitudes about this disease, and their socioeconomic determinants in the Bata district of Equatorial Guinea. A cross-sectional study was conducted in the district of Bata, involving 440 houses selected from 18 rural villages and 26 urban neighbourhoods. A combined "Malaria Knowledge Score" was generated based on caregivers' knowledge about transmission, symptoms, prevention, the treatment of children, and best place to seek treatment. Multivariate logistic regressions analyses were performed to assess those factors that are associated with knowledge about malaria. A total of 428 caregivers were interviewed; 255 (59.6%) and 173 (40.4%) lived in urban and rural areas respectively. Significant differences between rural and urban households were observed in caregivers' malaria knowledges and beliefs. Almost 42% of urban and 65% of rural caregivers were unaware as to how malaria is transmitted (OR = 2.69; 95% CI: 1.78-4.05). Together with rurality, the factors most significantly associated with the Malaria Knowledge were the level of education of the caregiver and the socioeconomic status of the household. Improvements in educational programs are needed to empower the most vulnerable households such that they can pro-actively implement malaria control measures. This could be achieved by a comprehensive communication strategy aimed at changing individual and community behaviours, and delivered by suitably trained community health workers and indoor residual spraying personnel.

Directional change in tunneling of subterranean termites (Isoptera: Rhinotermitidae) in response to decayed wood attractants.

PubMed

Su, Nan-Yao

2005-04-01

Wood discs decayed with brown rot fungi and polymer discs impregnated with acetone extract of decayed wood were embedded in sand of a two-dimensional foraging arena to evaluate their attractant potential in directing termite tunnels toward them. Termites were released near one arena corner and were guided to follow the physical guideline of the arena edges. In the absence of the attractants, termites generally formed a relatively linear tunnel along the edges. When decayed wood discs or treated polymer discs were placed in wet sand near one side of the arena, termite tunnels departed from the arena edges and were oriented toward them. The attraction distance ranged from 12 to 18 cm. The attractant properties were most likely water soluble and permeated through wet sand to cause termites to change their orientation. The results demonstrated that when such attractants are placed near a bait station in the field, they may be used to direct termite foraging toward the station.

To evaluate whether or not an educational intervention would lead to a change in knowledge and attitudes about human papillomavirus (HPV), HPV vaccines, and cervical cancer. The HPV status was also investigated for interested participants. We provided HPV and cervical cancer education to urban American Indian (AI) women 18 and older using a pre and post-knowledge exam to assess knowledge and attitudes. Women were also given the option to perform vaginal self-tests for high risk HPV (hrHPV) analysis immediately after the education. Ninety-six women participated in our educational sessions. Improvement in performance on a knowledge exam increased from 61.6 to 84.3 percent. Ninety-three women performed the vaginal self-test with 63.1 percent of women preferring vaginal self-testing over conventional screening methods. Thirty-five out of 91 women (38.5 percent) had hrHPV types with 12 of the 35 harboring multiple hrHPV types (13 percent overall). HPV and cervical cancer education was beneficial for urban AI women with the majority of women preferring vaginal self-testing. HPV self-testing may be a strategy to improve screening rates for cervical cancer. Urban AI women had high rates of hrHPV compared to rural AI populations as reported in previous studies.

Pathways as a tool for the governance of sustainable management of soilsubsidence

NASA Astrophysics Data System (ADS)

Ellen, G. J.; Hommes, S.

2017-12-01

Subsidence is a physical, societal, economic and institutional challenge for the Netherlands. For urban areas because subsidence threatens the nearby future the liveability and touristic attractiveness of the historic cities. For the rural areas because it affects the - intensive - agricultural landuse which is an important pilar of the Dutch economy. Policy and decision-making concerning subsidence is suffering from `non-decision making'. Subsidence has been described and mapped based on (geological and geotechnical) scientific research, but the subject has only been marginally addressing in the national, regional and local policy arena's. To actually make it possible for subsidence to be discussed in the policy arena a method was designed which was used in two cases : the Dutch city of Gouda and a more rural area in the province of Flevoland in the middle of the Netherlands. The method used was based on three building blocks. First of all future perspectives - scenario planning methodology was used to create future perspectives on coping with land subsidence. For example for Gouda we created 4 future perspectives for 2060 distinguishing between allocation of responsibilities (public or private) and the strategic decision to cope with land subsidence (halt or continue to sink). The second building block was the use of pathways, were each pathway consisted of a cluster of land subsidence strategies covering the many dimensions of land subsidence, ranging from houses and their foundations for the city of Gouda towards different types of agricultural land use for the rural area in the province of Flevoland. The last building block was a governance design approach were for every pathway a governance arrangements were designed together with stakeholders. The method was evaluated and proved to be very useful. First, a better understanding of the unsustainability of subsidence was obtained. In addition, the different perspectives and strategies stimulated discussions within the policy arena's on what might be needed especially in terms of governance. Finally, after applying the described method a higher awareness has been gained on `non-decision making' and ways to move forward.

2017-01-01

In May 2017, a two-day workshop was held in Los Angeles (California, U.S.A.) to gather practitioners who work with low-cost sensors used to make air quality measurements. The community of practice included individuals from academia, industry, non-profit groups, community-based organizations, and regulatory agencies. The group gathered to share knowledge developed from a variety of pilot projects in hopes of advancing the collective knowledge about how best to use low-cost air quality sensors. Panel discussion topics included: (1) best practices for deployment and calibration of low-cost sensor systems, (2) data standardization efforts and database design, (3) advances in sensor calibration, data management, and data analysis and visualization, and (4) lessons learned from research/community partnerships to encourage purposeful use of sensors and create change/action. Panel discussions summarized knowledge advances and project successes while also highlighting the questions, unresolved issues, and technological limitations that still remain within the low-cost air quality sensor arena.

Huerta, Timothy

2006-01-01

As the authors of the lead paper recognize, networks have become an increasingly popular form of organizing, both in the delivery of public services and within political arenas. A network is an arrangement of individuals and/or organizations that are linked through connections that range from informal relationships to formally agreed protocols. Networks have proved useful in addressing complex and intractable problems that require a holistic approach to identifying and implementing long-term solutions. They succeed in situations where hierarchies and "silo-based" systems have failed, and are particularly valuable in facilitating the transfer of resources and knowledge across sectoral and organizational boundaries.

Research Issues in Genetic Testing of Adolescents for Obesity

Segal, Mary E.; Sankar, Pamela; Reed, Danielle R.

2006-01-01

Obesity is often established in adolescence, and advances are being made in identifying its genetic underpinnings. We examine issues related to the eventual likelihood of genetic tests for obesity targeted to adolescents: family involvement; comprehension of the test’s meaning; how knowledge of genetic status may affect psychological adaptation; minors’ ability to control events; parental/child autonomy; ability to make informed medical decisions; self-esteem; unclear distinctions between early/late onset for this condition; and social stigmatization. The public health arena will be important in educating families about possible future genetic tests for obesity. PMID:15478685

Twichell, Sarah; Wang, Kathleen; Robinson, Humaira; Acebal, Maria; Sharma, Hemant

2015-07-21

Since food allergy knowledge and perceptions may influence prevention and management of school-based reactions, we evaluated them among nurses in an urban school district. All District of Columbia public school nurses were asked to anonymously complete a food allergy knowledge and attitude questionnaire. Knowledge scores were calculated as percentage of correct responses. Attitude responses were tabulated across five-point Likert scales, ranging from strongly disagree to strongly agree. The knowledge questionnaire was completed by 87% of eligible nurses and the attitude questionnaire by 83%. The mean total knowledge score was 76 ± 13 with domain score highest for symptom recognition and lowest for treatment. Regarding attitudes, most (94%) felt food allergy is a serious health problem, for which schools should have guidelines (94%). Fewer believed that nut-free schools (82%) and allergen-free tables (44%) should be implemented. Negative perceptions of parents were identified as: parents of food-allergic children are overprotective (55%) and make unreasonable requests of schools (15%). Food allergy knowledge deficits and mixed attitudes exist among this sample of urban school nurses, particularly related to management of reactions and perceptions of parents. Food allergy education of school nurses should be targeted to improve their knowledge and attitudes.

In this paper, we designed a reliable and image configurable flight arena, RICA, for developing cyborg bumblebees. To meet the spatial and temporal requirements of bumblebees, the Controller Area Network (CAN) bus is adopted to interconnect the LED display modules to ensure the reliability and real-time performance of the arena system. Easily-configurable interfaces on a desktop computer implemented by python scripts are provided to transmit the visual patterns to the LED distributor online and configure RICA dynamically. The new arena system will be a power tool to investigate the quantitative relationship between the visual inputs and induced flight behaviors and also will be helpful to the visual-motor research in other related fields.

Dengue fever is a major public health problem in Malaysia. This study aimed to assess factors affecting knowledge, attitudes, and practices regarding dengue fever among a selected population in Malaysia. A descriptive, community-based, cross sectional study was conducted with 300 participants from three different geographical settings in urban, semi-urban, and rural areas within the states of Selangor and Kuala Lumpur. The questionnaire included questions on demographic data, knowledge, attitudes, and practices regarding dengue fever. Mean age of respondents was 34.4 (+/- 5.7) years, and the age ranged from 18 to 65 years. The majority of respondents were married (54.7%), Malays (72.7%) and heard about dengue fever (89.7%). Television was the common source of information about dengue fever (97.0%). Participants answered 4 out of 15 items of knowledge incorrectly. There was no significant association between knowledge score and socio-demographic factors. About one-fifth of the respondents (24%) believed that immediate treatment is not necessary for dengue fever, and the majority of them were not afraid of the disease (96.0%). Attitudes toward dengue fever were significantly associated with the level of education and employment status (p < 0.05). Practice was associated significantly with age, marital status, and geographic area (p < 0.05) and knowledge on dengue fever (p = 0.030). There is a need to increase health promotion activities through campaigns and social mobilization to increase knowledge regarding dengue fever. This would help to mold positive attitudes and cultivate better preventive practices among the public to eliminate dengue in the country.

Urban climate, weather and sustainability

NASA Astrophysics Data System (ADS)

Mills, Gerald

As concentrated areas of human activities, urban areas and urbanization are key drivers of global environmental change and pose a challenge to the achievement of sustainability. One of the key goals of sustainable development is to separate increases in non-renewable resource use (particularly fossil fuels) from economic growth. This is to be accomplished by modifying individual practices, encouraging technological innovation and redesigning systems of production and consumption. Settlements represent a scale at which significant advances on each of these can be made and where there is an existing management structure. However, urban areas currently consume a disproportionate share of the Earth's resources and urbanization has modified local climate and weather significantly, usually to the detriment of urban dwellers. There is now a lengthy history of urban climate study that links existing settlement form to climatic consequences yet, there is little evidence that climate information is incorporated into urban designs or that the climatic impact of different plans is considered. Consequently, opportunities for planning sustainable urban forms that are suitable to local climates and promote energy conservation and healthy atmospheres are not taken and much effort is later expended in `fixing' problems that emerge. This paper will outline the links between urban climate and sustainability, identify gaps in our urban climate knowledge and discuss the opportunities and barriers to the application of this knowledge to urban design and planning.

La presente these s'inscrit dans le cadre d'un projet strategique sur les arenas finance par le CRSNG (Conseil de Recherche en Sciences Naturelles et en Genie du Canada) qui a pour but principal le developpement d'un outil numerique capable d'estimer et d'optimiser la consommation d'energie dans les arenas et curlings. Notre travail s'inscrit comme une suite a un travail deja realise par DAOUD et coll. (2006, 2007) qui a developpe un modele 3D (AIM) en regime transitoire de l'arena Camilien Houde a Montreal et qui calcule les flux de chaleur a travers l'enveloppe du batiment ainsi que les distributions de temperatures et d'humidite durant une annee meteorologique typique. En particulier, il calcule les flux de chaleur a travers la couche de glace dus a la convection, la radiation et la condensation. Dans un premier temps nous avons developpe un modele de la structure sous la glace (BIM) qui tient compte de sa geometrie 3D, des differentes couches, de l'effet transitoire, des gains de chaleur du sol en dessous et autour de l'arena etudie ainsi que de la temperature d'entree de la saumure dans la dalle de beton. Par la suite le BIM a ete couple le AIM. Dans la deuxieme etape, nous avons developpe un modele du systeme de refrigeration (REFSYS) en regime quasi-permanent pour l'arena etudie sur la base d'une combinaison de relations thermodynamiques, de correlations de transfert de chaleur et de relations elaborees a partir de donnees disponibles dans le catalogue du manufacturier. Enfin le couplage final entre l'AIM +BIM et le REFSYS a ete effectue sous l'interface du logiciel TRNSYS. Plusieurs etudes parametriques on ete entreprises pour evaluer les effets du climat, de la temperature de la saumure, de l'epaisseur de la glace, etc. sur la consommation energetique de l'arena. Aussi, quelques strategies pour diminuer cette consommation ont ete etudiees. Le considerable potentiel de recuperation de chaleur au niveau des condenseurs qui peut reduire l'energie requise par le systeme de ventilation de l'arena a ete mis en evidence. Mots cles.

Rabies is an important zoonosis in the public and veterinary healthy arenas. This article provides information on the situation of current rabies outbreak, analyzes the current national rabies control system, reviews the weaknesses of the national rabies control strategy, and identifies an appropriate solution to manage the current situation. Current rabies outbreak was shown to be present from rural areas to urban regions. Moreover, the situation worldwide demonstrates that each nation struggles to prevent or control rabies. Proper application and execution of the rabies control program require the overcoming of existing weaknesses. Bait vaccines and other complex programs are suggested to prevent rabies transmission or infection. Acceleration of the rabies control strategy also requires supplementation of current policy and of public information. In addition, these prevention strategies should be executed over a mid- to long-term period to control rabies.

Food fortification is the addition of one or more essential nutrients to a food whether or not it is normally contained in the food, for the purpose of preventing or correcting a demonstrated deficiency of one or more nutrients in the population or specific population groups. The present cross-sectional study was conducted to obtain comprehensive information towards consumption of Targeted Fortified Products (TFP) among rural and urban mothers of children <3 years in Jaipur, India. In this cross-sectional study conducted in 2012, three hundred rural and urban mothers were selected from Primary Health Centre, Achrol Village and Uniara Hospital in Jaipur, Rajasthan. The data were collected using a selfadministered questionnaire. The current nutritional status of children was determined by anthropometric measurements. A total of 53.33% rural and 65.33% urban mothers had knowledge (P=0.046), amongst which 52.67% rural and 66.00% urban mothers (P= 0.026) consumed TFP directed towards mothers. In addition, 56% rural and 94.67% urban mothers had knowledge (P=0.000) about TFP directed towards children, amongst which 19.33% rural and 50.67% urban mothers (P=0.000) fed their children with TFP. There was significantly less awareness regarding consumption of TFP directed towards both pregnant women and children among rural when compared to urban population. Attitudes seemed to be governed by the traditional beliefs and family influences of region rather than the knowledge obtained. There is a need of intensive coordinated efforts to create awareness among mothers to enhance the maternal and child diets through TFP.

We compared sexual and reproductive health (SRH)-related knowledge, attitude and behavior among unmarried rural-urban female migrants in Shanghai coming from different regions of China. A total of 944 unmarried rural-urban female migrants were recruited from three districts of Shanghai. We used an interviewer-administered structured questionnaire to collect information from each participant and a multivariate logistic regression to examine the association between premarital sex and risk factors. We found the rates of premarital sex, pregnancy and abortion among unmarried rural-urban female migrants were 28.2%, 5.2% and 5.0%, respectively. Participants from the east of China were more likely to engage in premarital sex than those from the mid-west (p < 0.001). The analysis showed premarital sex was associated with age, hometown, education, current residential type, knowledge of sexual physiology and safe sex, attitude to SRH and safe sex, and permissive attitude to sex. Unmarried rural-urban female migrants lack SRH related knowledge and the data suggests high levels of occurrence of premarital sex. The results indicate that programs to promote safe sex, especially to those migrants coming from eastern China, should be a priority. PMID:23939391

Assessing the adequacy of knowledge, attitude and practice of women regarding male and female condoms as STI/HIV preventive measures. An evaluative Knowledge, Attitude and Practice (KAP) household survey with a quantitative approach, involving 300 women. Data collection took place between June and August 2013, in an informal urban settlement within the municipality of João Pessoa, Paraiba, Northeast Brazil. Regarding the male condom, most women showed inadequate knowledge and practice, and an adequate attitude. Regarding the female condom, knowledge, attitude and practice variables were unsatisfactory. Significant associations between knowledge/religious orientation and attitude/education regarding the male condom were observed. A multidisciplinary team should be committed to the development of educational practices as care promotion tools in order to improve adherence of condom use.

To find the nutritional knowledge among mothers of one child of the poor community and to relate status of education to the nutritional health of them and the newborn and to get a thorough knowledge on the impact of nutritional education, a comprehensive study was undertaken in an urban slum area. Nutritional grading was done through scoring system. There were 47 mothers (24.1%) out of 195 having normal nutritional grade and 37 mothers (19%) having severe nutritional grade. There were 80 mothers having 'no knowledge' on maternal nutrition. 'Adequate knowledge' was found in 31 cases. Mothers (n = 80) of 'no knowledge' delivered babies of average weight 2.3 kg whereas 'adequate knowledge' mothers gave birth to babies of average weight 2.9 kg.

Medicinal plants used by women in Mecca: urban, Muslim and gendered knowledge.

This study explores medicinal plant knowledge and use among Muslim women in the city of Mecca, Saudi Arabia. Ethnobotanical research in the region has focused on rural populations and male herbal healers in cities, and based on these few studies, it is suggested that medicinal plant knowledge may be eroding. Here, we document lay, female knowledge of medicinal plants in an urban centre, interpreting findings in the light of the growing field of urban ethnobotany and gendered knowledge and in an Islamic context. Free-listing, structured and semi-structured interviews were used to document the extent of medicinal plant knowledge among 32 Meccan women. Vernacular names, modes of preparation and application, intended therapeutic use and emic toxicological remarks were recorded. Women were asked where they learnt about medicinal plants and if and when they preferred using medicinal plants over biomedical resources. Prior informed consent was always obtained. We compared the list of medicinal plants used by these Meccan women with medicinal plants previously documented in published literature. One hundred eighteen vernacular names were collected, corresponding to approximately 110 plants, including one algae. Of these, 95 were identified at the species level and 39 (41%) had not been previously cited in Saudi Arabian medicinal plant literature. Almost one half of the plants cited are food and flavouring plants. Meccan women interviewed learn about medicinal plants from their social network, mass media and written sources, and combine biomedical and medicinal plant health care. However, younger women more often prefer biomedical resources and learn from written sources and mass media. The fairly small number of interviews conducted in this study was sufficient to reveal the singular body of medicinal plant knowledge held by women in Mecca and applied to treat common ailments. Plant availability in local shops and markets and inclusion in religious texts seem to shape the botanical diversity used by the Meccan women interviewed, and the use of foods and spices medicinally could be a global feature of urban ethnobotany. Ethnobotanical knowledge among women in Islamic communities may be changing due to access to mass media and biomedicine. We recognise the lack of documentation of the diversity of medicinal plant knowledge in the Arabian Peninsula and an opportunity to better understand gendered urban and rural knowledge.

The contraceptive information and services offered to single women in most developing countries is compromised by stigma attached to premarital sex. This study was to ascertain the knowledge, attitude and practice of contraception among single women in a rural and urban community in southeast Nigeria, using a cross-sectional survey of 279 and 295 single women in Ngwo (rural) and Enugu (urban) community. The mean age of the population was 21.3 years. Contraceptive awareness was more among the urban than rural respondents (90.2% vs 34.1%). The major sources of contraceptive knowledge were mass media (68%) and peer groups (86.3%) for the urban and rural respondents, respectively. Most respondents in both groups had positive attitude towards contraception. More urban than rural respondents (68.3% vs 12.5%) began sexual activity during adolescence and the level of contraceptive use during first coitus were 48.4% and 13.7%, respectively. Of the currently sexually active respondents, 32.5% (rural) and 59.7% (urban) were using a form of modern contraception. Condoms, followed by oral pills were the most popular contraceptive method because they can easily procure them over the counter. Poor contraceptive information, highly critical behavior of family planning providers towards unmarried women seeking contraception and attitude of male partners militate against contraceptive practice. There is need to promote information and education on contraception among single women, their male partners and family planning providers.

Relevance of visual cues for orientation at familiar sites by homing pigeons: an experiment in a circular arena.

Gagliardo, A.; Odetti, F.; Ioalè, P.

2001-01-01

Whether pigeons use visual landmarks for orientation from familiar locations has been a subject of debate. By recording the directional choices of both anosmic and control pigeons while exiting from a circular arena we were able to assess the relevance of olfactory and visual cues for orientation from familiar sites. When the birds could see the surroundings, both anosmic and control pigeons were homeward oriented. When the view of the landscape was prevented by screens that surrounded the arena, the control pigeons exited from the arena approximately in the home direction, while the anosmic pigeons' distribution was not different from random. Our data suggest that olfactory and visual cues play a critical, but interchangeable, role for orientation at familiar sites. PMID:11571054

Developing Sustainable Urban Water-Energy Infrastructures: Applying a Multi-Sectoral Social-Ecological-Infrastructural Systems (SEIS) Framework

NASA Astrophysics Data System (ADS)

Ramaswami, A.

2016-12-01

Urban infrastructure - broadly defined to include the systems that provide water, energy, food, shelter, transportation-communication, sanitation and green/public spaces in cities - have tremendous impact on the environment and on human well-being (Ramaswami et al., 2016; Ramaswami et al., 2012). Aggregated globally, these sectors contribute 90% of global greenhouse gas (GHG) emissions and 96% of global water withdrawals. Urban infrastructure contributions to such impacts are beginning to dominate. Cities are therefore becoming the action arena for infrastructure transformations that can achieve high levels of service delivery while reducing environmental impacts and enhancing human well-being. Achieving sustainable urban infrastructure transitions requires: information about the engineered infrastructure, and its interaction with the natural (ecological-environmental) and the social sub-systems In this paper, we apply a multi-sector, multi-scalar Social-Ecological-Infrastructural Systems framework that describes the interactions among biophysical engineered infrastructures, the natural environment and the social system in a systems-approach to inform urban infrastructure transformations. We apply the SEIS framework to inform water and energy sector transformations in cities to achieve environmental and human health benefits realized at multiple scales - local, regional and global. Local scales address pollution, health, wellbeing and inequity within the city; regional scales address regional pollution, scarcity, as well as supply risks in the water-energy sectors; global impacts include greenhouse gas emissions and climate impacts. Different actors shape infrastructure transitions including households, businesses, and policy actors. We describe the development of novel cross-sectoral strategies at the water-energy nexus in cities, focusing on water, waste and energy sectors, in a case study of Delhi, India.

Larson, Elaine L; Ferng, Yu-Hui; McLoughlin, Jennifer Wong; Wang, Shuang; Morse, Stephen S

2009-01-01

Although upper respiratory infections (URIs) take a major social and economic toll, little research has been conducted to assess the impact of educational interventions on knowledge, attitudes, and practices of community members regarding prevention and treatment of URIs, particularly among recently immigrated urban Latinos who may not be reached by the mainstream healthcare system. The objective of this study was to assess the impact of a culturally appropriate, home-based educational intervention on the knowledge, attitudes, and practices regarding prevention and treatment of URIs among urban Latinos. Using a pretest-posttest design, Spanish-language educational materials available from sources such as the Centers for Disease Control and Prevention were adapted based on feedback from community focus groups and provided to households during an in-person home visit every 2 months (generally three to four visits). Outcome data regarding knowledge, attitudes, and practices were collected in home-based interviews using an 85-item instrument adapted and pilot tested from three other validated instruments. Nonparametric and multiple linear regression analyses were used to summarize data and identify predictors of knowledge scores. Four hundred twenty-two households had complete data at baseline and 6 months. Knowledge and attitude scores were improved significantly, and use of alcohol hand sanitizer and rates of influenza vaccine were increased significantly (all p <.01). Although this home-based educational intervention was successful in improving knowledge, attitudes, and self-reported practices among urban Latinos regarding prevention and treatment of URIs, further research is needed to determine the cost-effectiveness of such a person-intensive intervention, the long-term outcomes, and whether less intensive interventions might be equally effective.

Agency, contract and governance: shifting shapes of accountability in the health care arena.

PubMed

Tuohy, Carolyn Hughes

2003-01-01

Current ideas about the role of the state include an enthusiasm for mechanisms of "indirect" or "third-party" governance. The health care arena, in which models of indirect governance have a long history, is an important test bed for these ideas. Classically, the arena was marked by trust-based, principal-agent relationships established to overcome information gaps. Over time (and to different degrees across nations), emphasis shifted to contractual relationships assuming relatively well-informed actors and then to performance monitoring and information sharing within complex and loosely coupled networks. In this latest stage, there is a risk that some important features of democratic leadership, and of decision making in the health care arena, will be eclipsed. Accountability mechanisms must clearly locate responsibility for actions and must allow for the exercise of professional judgment.

To assess the knowledge, attitudes and behaviour of men and women towards health risks and benefits associated with urban dairy farming in smallholder dairy farming and their immediate non-dairy farming neighbour households. A cross sectional study and participatory urban appraisal (PUA. Urban and peri-urban households in Dagoretti Division, Nairobi. Three hundred dairy farming households, and 150 non-dairy farming neighbour households and six participatory urban appraisals, 58 males and 45 females. There were more females than males dairy farmers. Both women and men had equal access to resources and benefits obtained from dairy farming but the men had the greater control over the resources. Low levels of knowledge on the specific health risks related to urban dairy farming were observed. Less than half of the respondents believed they were at risk of being exposed to the health hazards, while 63% sensed they could protect themselves from the health risks. There was an association between knowledge levels, perceptions and behaviour of men and women toward risks associated with dairy farming. Apart from giving treatment to animals most men did less dairy farming activities. Women rated men lower in all dairy activities but when the men did the scoring for the same activities they rated themselves higher, arguing that their participation was indirect such as providing cash to buy the feed supplements and veterinary services. There were gender differences in all important tasks associated with dairy keeping. Farmers stated that older children, when not in school sometimes assisted but in general children did not show much enthusiasm in dairy work.

Poor teamwork is an important factor in the occurrence of critical incidents because of a lack of non-technical skills. Team training can be a key to prevent these incidents. The purpose of this study was to explore the experience of nursing and medical students after a simulation-based interprofessional team training (SBITT) course and its impact on professional and patient safety practices, using a concurrent mixed-method design. The participants (n = 262) were organized into 44 interprofessional teams. The results showed that two training sequences the same day improved overall team performance. Making mistakes during SBITT appeared to improve the quality of patient care once the students returned to clinical practice as it made the students more vigilant. Furthermore, the video-assisted oral debriefing provided an opportunity to strengthen interprofessional teamwork and share situational awareness. SBITT gave the students an opportunity to practice clinical reasoning skills and to share professional knowledge. The students conveyed the importance of learning to speak up to ensure safe patient practices. Simulated settings seem to be powerful arenas for learning patient safety practices and facilitating transference of this awareness to clinical practice. Copyright © 2016 Elsevier Ltd.

The aim of this paper is to present the result of a pioneer project; A Nordic Charter for Universal Design, which was initiated by the Norwegian Directorate for Children, Youth and Family Affairs in 2011. The purpose of the Charter was to present rationales that stated prerequisites for successful investment in Universal Design, and to establish a platform for further research and good practice. It was also meant to contribute to spreading of information and knowledge about the importance of guidance by the concept of Universal Design of initiatives with effects on the public arena. A Nordic group of researchers and professionals in the field ended up after 8 months of work with a written document: "A Nordic Charter for Universal Design", which was presented at the International Conference in Universal Design in Oslo, Norway (UD 2012). A Nordic Charter for Universal Design. Persons with disabilities often experience the public arenas environments, products and services as poorly-designed to fit their abilities and/or their needs. Together with the demographic changes in the Nordic societies with an increasing number of elderly people, it needs initiatives to improve independence, accessibility and participation in society. A strategy which aims to make design and composition of different environments, products, communication, information technology and services accessible, usable and understandable to as many as possible is Universal Design.

Rasing the ivory tower: the production of knowledge and distrust of medicine among African Americans

PubMed Central

Wasserman, J; Flannery, M A; Clair, J M

2007-01-01

African American distrust of medicine has consequences for treatment seeking and healthcare behaviour. Much work has been done to examine acute events (eg, Tuskegee Syphilis Study) that have contributed to this phenomenon and a sophisticated bioethics discipline keeps watch on current practices by medicine. But physicians and clinicians are not the only actors in the medical arena, particularly when it comes to health beliefs and distrust of medicine. The purpose of this paper is to call attention not just to ethical shortcomings of the past, but to the structural contexts of those events and the contributions and responsibilities of popular media and academic disciplines in the production of (often mythic) knowledge. We argue that ignoring context and producing inaccurate work has real impacts on health and healthcare, particularly for African Americans, and thus engenders ethical obligations incumbent on disciplines traditionally recognised as purely academic.

Curran, Janet; Abidi, Syed Sibte Raza

2006-01-01

Peer to peer knowledge sharing is recognized as a key contributor to the development of expert practice for health care professionals. Emergency departments with access to extensive expertise, such as in urban hospital settings, present greater potential for rich collaborative learning opportunities as compared with rural settings where expertise is at times scarce. Collaborative technologies such as electronic discussion boards may assist in leveling the "knowledge" playing field and increase opportunities for the growth of a strong social network for emergency clinicians. A social network perspective is used to explore the effectiveness of a discussion forum to support knowledge sharing among emergency practitioners in rural and urban emergency departments in Nova Scotia.

Cultural objects as objects: materiality, urban space, and the interpretation of AIDS campaigns in Accra, Ghana.

McDonnell, Terence E

2010-05-01

AIDS media lead unexpected lives once distributed through urban space: billboards fade, posters go missing, bumper stickers travel to other cities. The materiality of AIDS campaign objects and of the urban settings in which they are displayed structures how the public interprets their messages. Ethnographic observation of AIDS media in situ and interview data reveal how the materiality of objects and places shapes the availability of AIDS knowledge in Accra, Ghana. Significantly for AIDS organizations, these material conditions often systematically obstruct access to AIDS knowledge for particular groups. Attending to materiality rethinks how scholars assess the cultural power of media.

Adolescents constituted 19% population of India in 2011. Adolescents have health seeking behaviour different from that of adults. We estimated the utilisation of available health care services by adolescents and awareness regarding various health issues in the urban and rural Dehradun District, Uttarakhand, India. We also described knowledge and practices of public sector health care providers. We conducted a cross-sectional survey among adolescents 10-19 years in the urban Dehradun and rural Chakrata block of the Dehradun District. We used cluster sampling with sample size 680 each in urban and rural areas. We collected data from adolescents using semi structured questionnaire on health awareness and utilisation of health care services. Public sector health care providers were surveyed about their knowledge and practices regarding adolescents health. We surveyed 1463 adolescents. The overall mean age was 14.4 (2.6) years, about half being females. Half of the adolescents who had any illness used the public sector. Awareness about anaemia was 48% in urban and 12% in rural areas. A higher proportion of females (Rural: 89%, Urban: 76%) were aware of condoms as contraceptives than males (Rural: 68%, Urban: 12%). Only 62% of doctors and 49% of paramedical staff had knowledge regarding services under Adolescents Reproductive and Sexual Health (ARSH). Awareness regarding various health issues was low among males as compared to females, especially in rural areas. School based health promotion programs should be carried out to increase awareness among adolescents. Health facilities should be strengthened to provide adolescent friendly health services to enhance utilisation.

Nurses have a great deal of interaction with patients. Given this, nurses play a vital role in conveying to patients knowledge of their privacy, security, and confidentiality of patient health information rights under the Health Insurance Portability and Accountability Act (HIPAA). Nurses also can be "at the head of the table" in their own organization and professional organizations in regard to facilitating the implementation of the HIPAA and making access to patient information more "consumer friendly." This article discusses the role that nurses can develop into concerning HIPAA implementation in an ever-burgeoning arena of consumer advocacy and consumer information.

We characterize health knowledge and practices in urban and rural Makeni, Sierra Leone, drawing comparisons between areas served by community health workers (CHWs) with those that are not. We also inquire about causes of infant and maternal mortality and how they are understood in the local context. Our objective was to provide a baseline understanding of health knowledge and practices in Makeni during the implementation of a CHW program. We conducted 100 household interviews in Makeni City and rural villages in the surrounding area. We compared data between urban and rural areas to identify differences in health knowledge and practices. Our sample size covered 855 individuals. Insecticide treated bednet ownership was lower in urban settings compared to rural populations (58% vs 94%; p<.001). With regards to maternal mortality, most respondents indicated 'no clinic' (lack of clinical care or skipped antenatal care visits) as the primary cause (n=35), followed by bleeding (n=17), 'lack of blood' (anemia) (n=11) and 'will of God' (n=11). This initial survey of health knowledge and practices in rural and urban Makeni, Sierra Leone, highlights some simple opportunities for community health promotion, health education programming and behavioral interventions. Findings will inform future iterations of a CHW training module for community health education. © The Author 2015.

Community Knowledge about Water: Who Has Better Knowledge and Is This Associated with Water-Related Behaviors and Support for Water-Related Policies?

PubMed Central

Fielding, Kelly S.; Newton, Fiona J.

2016-01-01

Sustainable approaches to water management require broad community acceptance of changes in policy, practice and technology, which in turn, requires an engaged community. A critical first step in building an engaged community is to identify community knowledge about water management, an issue rarely examined in research. To address this, we surveyed a representative sample of Australian adults (n = 5172). Knowledge was assessed using 15 questions about impact of household activities on waterways, the urban water cycle, and water management. This survey also examined demographics, psychosocial characteristics, exposure to water-related information, and water-related behaviors and policy support. Participants correctly answered a mean of 8.0 questions (Range 0–15). Most respondents knew that household actions can reduce water use and influence waterway health, whereas less than one third correctly identified that domestic wastewater is treated prior to entering waterways, urban stormwater is not treated, and that these are carried via different pipes. Higher water knowledge was associated with older age, higher education and living in non-urban areas. Poorer water knowledge was associated with speaking a language other than English in the home. Garden size, experience of water restrictions, satisfaction, waterway use for swimming, and certain information sources were also associated with knowledge. Greater water knowledge was associated with adoption of water-saving and pollution-reduction behaviors, and support for both alternative water sources and raingardens. These findings confirm the importance of community knowledge, and identify potential subgroups who may require additional targeting to build knowledge and support for water management initiatives.

A high-fat high-sugar diet-induced impairment in place-recognition memory is reversible and training-dependent.

PubMed

Tran, Dominic M D; Westbrook, R Frederick

2017-03-01

A high-fat high-sugar (HFHS) diet is associated with cognitive deficits in people and produces spatial learning and memory deficits in rodents. Notable, such diets rapidly impair place-, but not object-recognition memory in rats within one week of exposure. Three experiments examined whether this impairment was reversed by removal of the diet, or prevented by pre-diet training. Experiment 1 showed that rats switched from HFHS to chow recovered from the place-recognition impairment that they displayed while on HFHS. Experiment 2 showed that control rats ("Untrained") who were exposed to an empty testing arena while on chow, were impaired in place-recognition when switched to HFHS and tested for the first time. However, rats tested ("Trained") on the place and object task while on chow, were protected from the diet-induce deficit and maintained good place-recognition when switched to HFHS. Experiment 3 examined the conditions of this protection effect by training rats in a square arena while on chow, and testing them in a rectangular arena while on HFHS. We have previously demonstrated that chow rats, but not HFHS rats, show geometry-based reorientation on a rectangular arena place-recognition task (Tran & Westbrook, 2015). Experiment 3 assessed whether rats switched to the HFHS diet after training on the place and object tasks in a square area, would show geometry-based reorientation in a rectangular arena. The protective benefit of training was replicated in the square arena, but both Untrained and Trained HFHS failed to show geometry-based reorientation in the rectangular arena. These findings are discussed in relation to the specificity of the training effect, the role of the hippocampus in diet-induced deficits, and their implications for dietary effects on cognition in people.

Experts, government officials, and industry leaders concerned about the sustainability of shrimp aquaculture believe they know what farmers need to know and should be doing. They have framed sustainability as a technical problem that, at the farm level, is to be solved by better shrimp and management of ponds and businesses. Codes of conduct, standards, and regulations are expected to bring deviant practices into line. Shrimp farmers are often cornered in a challenging game of knowledge in which their livelihoods are at stake. In the commodity chain there are multiple relations with both suppliers and buyers, not all of which are trustworthy. The social networks shrimp farmers belong to are crucial for sifting out misinformation and multiplying insights from personal experience in learning by doing. Successful farmers become part of a learning culture through seminars, workshops, and clubs in which knowledge and practices are continually re-evaluated. The combination of vertical and horizontal relationships creates a set of alternative arenas that together are critical to bridging knowledge and action gaps for shrimp farmers. Government and industry initiatives for improving links between knowledge and practice for sustainability have largely succeeded when incentives are aligned: shrimp grow better in healthy environments, and using fewer resources means higher profits.

Identification of potential opinion leaders in child health promotion in Sweden using network analysis.

PubMed

Guldbrandsson, Karin; Nordvik, Monica K; Bremberg, Sven

2012-08-08

Opinion leaders are often local individuals with high credibility who can influence other people. Robust effects using opinion leaders in diffusing innovations have been shown in several randomized controlled trials, for example regarding sexually transmitted infections (STI), human immunodeficiency virus (HIV) prevention, mammography rates and caesarean birth delivery rates. In a Cochrane review 2010 it was concluded that the use of opinion leaders can successfully promote evidence-based practice. Thus, using opinion leaders within the public health sector might be one means to speed up the dissemination of health promoting and disease preventing innovations. Social network analysis has been used to trace and map networks, with focus on relationships and positions, in widely spread arenas and topics. The purpose of this study was to use social network analysis in order to identify potential opinion leaders at the arena of child health promotion in Sweden. By using snowball technique a short e-mail question was spread in up to five links, starting from seven initially invited persons. This inquiry resulted in a network consisting of 153 individuals. The most often mentioned actors were researchers, public health officials and paediatricians, or a combination of these professions. Four single individuals were mentioned by five to seven other persons in the network. These individuals obviously possess qualities that make other professionals within the public health sector listen to and trust them. Social network analysis seemed to be a useful method to identify influential persons with high credibility, i.e. potential opinion leaders, at the arena of child health promotion in Sweden. If genuine opinion leaders could be identified directed measures can be carried out in order to spread new and relevant knowledge. This may facilitate for public health actors at the local, regional and national level to more rapidly progress innovations into everyday practice. However, effectiveness studies of opinion leaders in the public health sector still have to be performed.

Is eating science or common sense? Knowledge about "natural foods" among self-identified "natural food" consumers, vendors and producers in rural and urban Mexico.

PubMed

Kooijmans, Anneke; Flores-Palacios, Fátima

2014-10-01

To explore the common sense knowledge that consumers, vendors and producers hold of "natural foods". The focus was on common knowledge because this is infrequently explored in social psychology where most studies focus on the implementation of scientific knowledge. The focus was on natural foods because the naturalness of foods seems to be one of the particular concerns that current consumers have about today's food market and because a specific natural food preference was observed in the contexts of study. Fifty-seven informants in a rural context and 58 informants in an urban context participated in either a free association study or an interview study. Data content were analyzed. In the urban context natural foods obtain their significance in the relationship between food and the self-concept; eating natural (or good) food is a task that requires effort and attitude, and foods obtain a moral value. In the rural context natural foods obtain their significance as an expression of a social and cultural system of interdependence that establishes practices and customs that have a long history in the community. It is suggested that these common knowledge systems are related to practical challenges that are particular to the informants' context and that the structure of their common sense knowledge systems depend on the mediation of the flow of scientific knowledge and technological knowledge in each context.

This study assessed the public’s health risk awareness of urban air pollution triggered by three megacities in China, and the data are the responses from a sample size of 3868 megacity inhabitants from Shanghai, Nanchang and Wuhan. Descriptive analyses were used to summarize the respondents’ demographics, perceived health risks from air pollution and sources of health-related knowledge on urban air pollution. Chi-square tests were used to examine if participants’ demographics were associated with participant’s general attitudes towards current air quality and the three perceived highest health risks due to urban air pollution. We found low rate of satisfaction of current urban air quality as well as poor knowledge of air pollution related indicator. Participants’ gender, age and travel experience were found to be associated with the satisfaction of current air quality. The knowledge of air pollution related indicator was significantly affected by respondents’ education, monthly income, health status, and sites of study. As many as 46.23% of the participants expressed their feelings of anxiety when exposed to polluted air, especially females, older adults and those with poor health conditions. Most participants believed that coughs/colds, eye problems and skin allergies were the three highest health risks due to urban air pollution based on public education through television/radio, internet and newspaper/magazine. Further public health education is needed to improve public awareness of air pollution and its effects. PMID:27571088

The multiple partner choice arena (MPCA) is an experimental setup in which male rats display a significant shortening of ejaculation latency, which is the main characteristic of premature ejaculation (PE) in men. Thus, the MPCA is a potential animal model for PE. In this study, we further analyze whether the features of the MPCA satisfy the validity criteria for it to be considered an animal model as well as the possible participation of the serotoninergic system in the faster ejaculation exhibited by male rats in the MPCA. In Experiment 1, male rats were tested in a standard arena to assess their sexual behavior, then were assessed 1 week later in the MPCA. Another group was first tested in the MPCA, then in a standard arena. In Experiment 2, male rats divided into two groups were treated daily with WAY-100635 (5-HT(1A) antagonist) or vehicle for 15 days. In each group, half of the subjects were tested in a standard arena and half were tested in the MPCA on days 1, 8, and 15 of treatment. Number of intromissions and intromission and ejaculation latencies were the main outcome measures. In Experiment 1, males tested in the MPCA ejaculated significantly faster, regardless of the order in which they were evaluated in both arenas. In Experiment 2, the administration of WAY-100635 increased intromission and ejaculation latencies, and the number of intromissions in the MPCA. The results obtained in the MPCA support its use as an animal model for PE evaluation. © 2014 International Society for Sexual Medicine.

Orientation in a crowded environment: can King Penguin (Aptenodytes patagonicus) chicks find their creches after a displacement?

Nesterova, Anna P; Mardon, Jérôme; Bonadonna, Francesco

2009-01-01

For seabird species, the presence of conspecifics in a crowded breeding colony can obstruct locally available orientation cues. Thus, navigation to specific locations can present a challenging problem. We investigated short-range orientation in King Penguin (Aptenodytes patagonicus) chicks that live in a large and densely populated colony. The two main objectives were to determine whether chicks displaced to a novel location away from the colony (i) can orient towards the colony and return to their crèche and (ii) rely on visual or non-visual cues for orientation. To address these questions, a circular arena was constructed 100 m away from the colony. Chicks were released in the arena during the day and at night. After the orientation experiment in the arena, chicks were allowed to return to their home crèche, if they could. Our results showed that, during day trials, chicks preferred the half of the arena closer to the colony, but not at night. However, at night, birds spent more time on ;the colony half' of the arena if the wind blew from the colony direction. When animals were allowed to leave the arena, 98% of chicks homed during the day but only 62% of chicks homed at night. Chicks that homed at night also took longer to find their crèche. The experiments suggest that King Penguin chicks can find their crèche from a novel location. Visual cues are important for homing but, when visual cues are not present, animals are able to make use of other information carried by the wind.

The purpose of this study is to establish whether mental health (MH) outcomes, attitudes towards cancer-specific MH (CSMH) resources, and the availability of such resources differ between rural and urban cancer patients. Three months after surgery for colorectal cancer, patients received a questionnaire for completion at home assessing distress, depression, anxiety, acceptance, knowledge and use of CSMH resources and the doctor-patient relationship. We adjusted our sample to reference data of the Munich Cancer Registry and documented CSMH resources (e.g. cancer-specific information centres and cancer support groups) using a systematic Internet search. Five hundred thirty-four patients participated with a mean age of 68.9 years; 44.5 % were female. Urban patients talked less with their doctor about their emotional state (65 %, p < 0.01) and showed poorer knowledge of CSMH resources (60 %, p < 0.002). A good doctor-patient relationship was associated with a better MH outcome. A significant predictor for acceptance was distress. Ninety-four percent of patients without a nearby support facility lived in rural areas (p < 0.001). There were no group differences concerning distress, MH outcomes, or acceptance of CSMH resources. Despite a higher availability of CSMH resources, urban patients showed poorer doctor-patient relationships and less knowledge of such resources than rural patients. Overall, knowledge and use of these resources were poor. The amount of support facilities available therefore appears to be less important than establishing an efficient communication network between patients, doctors and providers of CSMH resources to achieve satisfaction with treatment of urban and rural cancer patients.

Many urban American Indian community members lack access to knowledgeable participation in indigenous spiritual practices. And yet, these sacred traditional activities remain vitally important to their reservation-based kin. In response, our research team partnered with an urban American Indian health center in Detroit for purposes of developing a structured program to facilitate more ready access to participation in indigenous spiritual knowledge and practices centered on the sweat lodge ceremony. Following years of preparation and consultation, we implemented a pilot version of the Urban American Indian Traditional Spirituality Program in the spring of 2016 for 10 urban AI community participants. Drawing on six first-person accounts about this program, we reflect on its success as a function of participant meaningfulness, staff support, mitigated sensitivities, and program structure. We believe that these observations will enable other community psychologists to undertake similar program development in service to innovative and beneficial impacts on behalf of their community partners. © Society for Community Research and Action 2017.

2012-01-01

Objectives Describe informal allopathic practitioner (IAP) knowledge and practice about management of hypertension and identify gaps in IAP knowledge and practice amenable to interventions. Methods A cross sectional descriptive survey of 642 IAPs in Kamalapur (urban) and Mirsarai (rural) Bangladesh was conducted from March to April, 2011. Using a structured, pre-tested questionnaire sociodemographic, training, knowledge and practice data about management of hypertension was collected. Comparative statistics were preformed to show differences between urban and rural practitioners using SAS 8.0. Findings 99.4% of IAPs were male, mean age was 37.5 (12.5 SD) years. Greater than 65% correctly identified the upper limit of normal blood pressure. 50.2% underestimated lower limit of systolic hypertension. 79.8% allowed age to affect their treatment approach. As blood pressure increased, willingness to treat with medication decreased and tendency to refer increased. Sedative/sleeping pills, antidepressants, and beta blockers were the most commonly prescribed medications for prehypertension (58.7%, 50.3% and 53.7% respectively), stage I hypertension (55.0%, 38.6%, 49.8% respectively) and stage II hypertension (42.4%, 23.7%, and 28.8% respectively). Rural IAPs were more likely than urban IAPs to treat (84.7% vs 77.7%), order tests (27.1% vs 6.0%) and write prescriptions (60.4% vs 18.7%). Conclusion While IAPs are crucial to Bangladesh’s pluralistic healthcare system, gaps in knowledge and practice could cause unnecessary harm. To include IAPs in the public sector’s fight against the chronic disease epidemic, interventions aimed at standardizing IAPs knowledge and practice will be essential. Successfully utilizing IAPs will have beneficial implications not only for Bangladesh, but for all developing countries. PMID:23133546

The NSF-RCN Urban Heat Island Network

In much of the world cities are warming at twice the rate of outlying rural areas. The frequency of urban heat waves is projected to increase with climate change through the 21stcentury. Addressing the economic, environmental, and human costs of urban heat islands requires a better understanding of their behavior from many disciplinary perspectives. The goal of this four-year Urban Heat Island Network is to (1) bring together scientists studying the causes and impacts of urban warming, (2) advance multidisciplinary understanding of urban heat islands, (3) examine how they can be ameliorated through engineering and design practices, and (4) share these new insights with a wide array of stakeholders responsible for managing urban warming to reduce their health, economic, and environmental impacts. The Urban Heat Island Network involves atmospheric scientists, engineers, architects, landscape designers, urban planners, public health experts, and education and outreach experts, who will share knowledge, evaluate research directions, and communicate knowledge and research recommendations to the larger research community as well as stakeholders engaged in developing strategies to adapt to and mitigate urban warming. The first Urban Climate Institute was held in Saint Paul, Minnesota in July 2013 and focused on the characteristics of urban heat islands. Scientists engaged with local practitioners to improve communication pathways surrounding issues of understanding, adapting to, and mitigating urban warming. The second Urban Climate Institute was held in Atlanta, Georgia in July 2014 and focused on urban warming and public health. Scientists discussed the state of the science on urban modeling, heat adaptation, air pollution, and infectious disease. Practitioners informed participants on emergency response methods and protocols related to heat and other extreme weather events. Evaluation experts at the Science Museum of Minnesota have extensively evaluated both Institutes to improve future Institutes and to inform other research coordination networks. Two more Institutes are planned for 2015 and 2016 focusing on urban warming and the built environment, and education and outreach.

This study evaluated the predatory capacity of Euseius alatus (DeLeon) as a biological control agent of the pest mite Oligonychus ilicis (McGregor) on coffee leaves under laboratory conditions, using arenas containing 25 O. ilicis per coffee (Coffea arabica) leaf to one specimen of each stage of the predator mite. The functional response and oviposition rate of adult females of E. alatus were evaluated on coffee leaf arenas and offered from 1 to 125 immature stages of O. ilicis per arena. The number of preys killed and the number of eggs laid by the predator were evaluated every 24 h during 8 days. The preys consumed were daily replaced. Male and female adults of E. alatus were the most efficient in killing all developmental stages of O. ilicis. Larvae and nymphs of O. ilicis were the most consumed by all stages of the predatory mite. The functional response and oviposition rates of E. alatus increased as the prey density increased, with a positive and highly significant correlation. Regression analysis suggested a type II functional response, with a maximum predation of 22 O. ilicis/arena and a maximum oviposition rate of 1.7 eggs/day at a density of 70 O. ilicis/arena.

2017-09-01

We examine the link between maternal nutrition knowledge and nutritional outcomes of children and adolescents (5-18 years) measured in terms of height-for-age Z-scores (HAZ). One particular focus is on the role of different types of nutrition knowledge. The analysis builds on household-level and individual-level data collected in urban Kenya in 2012 and 2015. Various regression models are developed and estimated. Results show that maternal nutrition knowledge - measured through an aggregate knowledge score - is positively associated with child HAZ, even after controlling for other influencing factors such as household living standard and general maternal education. However, disaggregation by type of knowledge reveals important differences. Maternal knowledge about food ingredients only has a weak positive association with child HAZ. For maternal knowledge about specific dietary recommendations, no significant association is detected. The strongest positive association with child HAZ is found for maternal knowledge about the health consequences of not following recommended dietary practices. These findings have direct relevance for nutrition and health policies, especially for designing the contents of educational campaigns and training programs. Copyright © 2017 Elsevier Ltd.

We assessed the differences and similarities in knowledge, attitude, beliefs, myths, and misconceptions; and the various high-risk behavioral factors that influence the rate of infectivity of human immunodeficiency virus (HIV)/AIDS among African American men in urban and rural communities of Mississippi. A cross-sectional sample survey was conducted on 466 African American men in 2 sites between 2005 and 2007. With the main outcome variables of knowledge, attitude/feelings, behavior/practices, and potentials for behavior change, we administered a 64-item, ethnically sensitive, gender-specific instrument to the subjects via a person-to-person interview. Of the 466 respondents (urban, 33%; rural, 67%), 70%, 14.4%, and 16.6%, respectively, were heterosexual, bisexual, and men who have sex with men (MSM). The number of the respondents' sexual partners in the previous 12 months were: 1 to 2 (54%), 3 to 4 (25.7%), and 5 or more (20.2%). Statistically significant differences were observed between the 2 populations on HIV knowledge (p < .001), HIV/sexually transmitted infection testing history (p < .001), sexual partners (p = .038), unprotected sexual intercourse with drug users (p < .001), unprotected casual sex (p < .001), intercourse in an open relationship or marriage (p < .001), and communication with potential sex partners regarding sexual limits prior to intercourse (p = .027). Although the level of HIV/AIDS knowledge and education were lower among urban than rural respondents, subjects' negative overall beliefs, attitude/feelings, behavior and potentials for behavioral change did not differ significantly among the African American men in the 2 communities.

Investigation of urban science teachers' pedagogical engagements: Are urban science teachers culturally responsive?

NASA Astrophysics Data System (ADS)

Udokwu, Chukwudi John

This study utilized mixed methodology of quantitative and qualitative research approach to explore the current pedagogical engagements of twenty middle school urban science teachers in the Midwest region of the United States. It qualitatively examined twelve of these teachers' knowledge of culturally responsive pedagogy. The study investigated the following questions: What are the current pedagogical practices of urban middle school science teachers? To what extent are middle school science teachers' pedagogical practices in urban schools culturally responsive? What are urban students' perspectives of their teachers' current pedagogical engagements? The design of the study was qualitative and quantitative methods in order to investigate these teachers' pedagogical practices. Data collections were drawn from multiple sources such as lesson plans, students' sample works, district curriculum, surveys, observational and interview notes. Analysis of collected data was a mixed methodology that involved qualitative and quantitative methods using descriptive, interpretative, pattern codes, and statistical procedures respectively. Purposeful sampling was selected for this study. Thus, demographically there were twenty participants who quantitatively took part in this study. Among them were seven (35%) males and thirteen (65%) females, three (15%) African Americans and seventeen (85%) Caucasians. In determining to what extent urban science teachers' pedagogical practices were culturally responsive, eight questions were analyzed based on four cluster themes: (a) teachers' social disposition, (b) culturally responsive curriculum, (c) classroom interactions, and (d) power pedagogy. Study result revealed that only five (25%) of the participants were engaged in culturally responsive pedagogy while fifteen (75%) were engaged in what Haberman (1991) called the pedagogy of poverty. The goal was to investigate urban science teachers' pedagogical engagements and to examine urban students' perspective of their science teachers' pedagogical practices, and ensure that all students have a sense of ownership of their knowledge, a sense that is empowering and liberating. The implications of these findings were to promote urban students' achievements in science and see them employed in science and engineering. I hope this study helps in developing better professional development that will be culturally responsive and to ensure that all students have a sense of ownership of their knowledge.

Leptospirosis disproportionately affects residents of urban slums. To understand the knowledge, attitudes, and practices regarding leptospirosis, we conducted a cross-sectional study among residents of an urban slum community in Salvador, Brazil. Of the 257 residents who were interviewed, 225 (90%) were aware of leptospirosis and more than two-thirds of respondents correctly identified the modes of disease transmission and ways to reduce exposure. However, study participants who performed risk activities such as cleaning open sewers had limited access to protective clothing such as boots (33%) or gloves (35%). Almost all respondents performed at least one activity to prevent household rat infestation, which often included use of an illegal poison. Our findings support the need for interventions targeted at the individual and household levels to reduce risk of leptospirosis until large-scale structural interventions are available to residents of urban slum communities.

As the central product of the BMBF-KLIMZUG-funded Joint Network and Research Project (JNRP) 'dynaklim - Dynamic adaptation of regional planning and development processes to the effects of climate change in the Emscher-Lippe region (North Rhine Westphalia, Germany)', the Roadmap 2020 'Regional Climate Adaptation' has been developed by the various regional stakeholders and institutions containing specific regional scenarios, strategies and adaptation measures applicable throughout the region. This paper presents the method, elements and main results of this regional roadmap process by using the example of the thematic sub-roadmap 'Water Sensitive Urban Design 2020'. With a focus on the process support tool 'KlimaFLEX', one of the main adaptation measures of the WSUD 2020 roadmap, typical challenges for integrated climate change adaptation like scattered knowledge, knowledge gaps and divided responsibilities but also potential solutions and promising chances for urban development and urban water management are discussed. With the roadmap and the related tool, the relevant stakeholders of the Emscher-Lippe region have jointly developed important prerequisites to integrate their knowledge, to clarify vulnerabilities, adaptation goals, responsibilities and interests, and to foresightedly coordinate measures, resources, priorities and schedules for an efficient joint urban planning, well-grounded decision-making in times of continued uncertainties and step-by-step implementation of adaptation measures from now on.

OBJECTIVE: To test the hypothesis that the higher prevalence of heart disease-related illnesses in women in urban areas may be attributed to lack of knowledge. DESIGN: A prospective survey of 224 women presenting to an urban emergency department. INTERVENTION: All study participants were surveyed about their knowledge of heart disease and associated risk factors. RESULTS: Two-hundred participants correctly completed the surveys. Only 25 (13%) of women correctly identified heart disease as the leading cause of death in women. Similarly, only 12 (6%) of women surveyed felt heart disease was the greatest health issue facing women today. The majority of women felt breast cancer was the most important health issue and responsible for the greatest mortality in women. Only three of the traditional cardiac risk factors were correctly identified by half of the women surveyed: hypercholesteremia (56%), hypertension (54%), and tobacco (52%). Family history was correctly identified by 44%, and only 20% of women felt diabetes was a risk factor for cardiovascular disease. CONCLUSIONS: Despite increased medical education and media time spent on women's health issues, up to 87% of women in this urban population did not know the leading cause of death for their gender.

Design of Urban Public Spaces: Intent vs. Reality

2018-01-01

This study investigated how two public spaces for sport and recreation were utilized by different user groups, and how this aligned with the initial design objectives for these spaces. Two newly built urban spaces situated in Copenhagen, Denmark, provided the context for this investigation. The System for Observing Play and Recreation in Communities (SOPARC) was used to examine the physical activity of users in these two urban spaces. The architects responsible for designing each space were interviewed to ascertain the intended target group of each space and to unravel the reasons behind the design decisions. The SOPARC observations revealed that males were more vigorously active than females when using the recreation facilities, and the observed users did not align with the intended target groups. The interviews suggested that design decisions were based on minimal interdisciplinary knowledge, and that expert knowledge was chosen randomly. These findings point to a systematic lack of evidence-based practice when designing sport and recreational facilities. This article has implications for landscape architects and urban planners; a new method must be developed to embed interdisciplinary knowledge in the planning process of future sport and recreation projects. This must be done in a systematic way to make the design process transparent. PMID:29690509

China is facing an emerging epidemic of syphilis, and the cities in south China are most affected. Knowledge is a key factor in the prevention of syphilis infection, however, little is reported about how much people know about syphilis. This study was aimed at assessing peoples' awareness status in a city located in south China. Six populations were recruited for this study, including urban residents, factory workers, college students, pregnant women, female sex workers (FSWs), and men who have sex with men (MSM). A questionnaire designed by the National Center for Disease Control and Prevention was used to assess participants' awareness of syphilis knowledge. About 5% of participants were randomly selected to conduct a telephone survey for confirming the validity of fieldwork. The study recruited 3470 participants, and 61.2% of participants were assigned to the awareness group. College students had the smallest percentage of awareness at 51.7% (371/718), followed by FSWs at 53.9% (200/371), factory workers at 56.0% (381/679), urban residents at 65.4% (435/665), pregnant women at 66.0% (451/683), and MSM at 81.1% (287/354). Multivariate logistic regression analysis showed that MSM and FSWs-but not factory workers and pregnant women-had more awareness of syphilis knowledge when comparing with urban residents; however, college students presented less awareness of syphilis knowledge than urban residents. Participants of younger age, of female gender, with lower education levels and without Shenzhen hukou possessed less awareness of syphilis knowledge than those of older age, of male gender, with higher education levels and with Shenzhen hukou respectively. The percentages of awareness on syphilis knowledge found in this study are far from the benchmark set in the national 10-year plan. Tailored interventions for different subgroups to increase syphilis awareness are urgently warranted.

Experiments were conducted to examine how several key factors affect population growth of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae). Laboratory experiments were conducted to examine effects of food quantity and temperature on reproduction of cohorts of young A. tumida adults (1:1 sex ratio) housed in experimental arenas. Daily numbers and total mass of larvae exiting arenas were highly variable within treatment. Either one or two cohorts of larvae were observed exiting the arenas. Food quantity, either 10 g or 20 g, did not significantly affect the number of larvae exiting arenas at 32°C, but did at 28°C; arenas provided 20 g food produced significantly more larvae than arenas provided 10 g. Temperature did not affect the total mass of larvae provided 10 g food, but did affect larval mass provided 20 g; beetles kept at 28°C produced more larval mass than at 32°C. Field experiments were conducted to examine A. tumida reproductive success in full strength bee colonies. Beetles were introduced into hives as egg-infested frames and as adults, and some bee colonies were artificially weakened through removal of sealed brood. Efforts were unsuccessful; no larvae were observed exiting from, or during the inspection of, any hives. Possible reasons for these results are discussed. The variability observed in A. tumida reproduction even in controlled laboratory conditions and the difficulty in causing beetle infestations in field experiments involving full colonies suggest that accurately forecasting the A. tumida severity in such colonies will be difficult.

Inhibition of GABAergic neural inputs to dorsal columns of the periaqueductal grey matter (dPAG), posterior (PH) and dorsomedial (DMH) hypothalamic nuclei elicits distinct types of escape behavioural reactions. To differentiate between the variety and intensity of panic-related behaviours, the pattern of defensive behaviours evoked by blockade of GABAA receptors in the DMH, PH and dPAG were compared in a circular open-field test and in a recently designed polygonal arena. In the circular open-field, the defensive behaviours induced by microinjection of bicuculline into DMH and PH were characterised by defensive alertness behaviour and vertical jumps preceded by rearing exploratory behaviour. On the other hand, explosive escape responses interspersed with horizontal jumps and freezing were observed after the blockade of GABAA receptors on dPAG neurons. In the polygonal arena apparatus, the escape response produced by GABAergic inhibition of DMH and PH neurons was directed towards the burrow. In contrast, the blockade of GABAA receptors in dPAG evoked non-oriented escape behaviour characterised by vigorous running and horizontal jumps in the arena. Our findings support the hypothesis that the hypothalamic nuclei organise oriented escape behavioural responses whereas non-oriented escape is elaborated by dPAG neurons. Additionally, the polygonal arena with a burrow made it easy to discriminate and characterise these two different patterns of escape behavioural responses. In this sense, the polygonal arena with a burrow can be considered a good methodological tool to discriminate between these two different patterns of escape behavioural responses and is very useful as a new experimental animal model of panic attacks.

To describe the patterns of handwashing behaviour among Chinese adults, and assess their associations with sociodemographic factors and knowledge of hand hygiene. A representative sample (n = 6159) of Chinese adults aged 18-60 years in five provinces was attained by multiple-stage, stratified sampling mainly based on geographical location and economic status. Data on handwashing behaviour, knowledge of hand hygiene and sociodemographic factors were collected through self-administrated questionnaires. Associations between handwashing behaviour and sociodemographic factors were tested in logistic models. Path analysis was applied to examine the associations between sociodemographic factors, knowledge of hand hygiene and proper handwashing behaviour in order to evaluate the relative magnitude of these determinants and internal relationships. This study found that 52.7% (rural vs urban: 44.6% vs 56.8%) and 67.3% (rural vs urban: 59.7% vs 71.1%) of Chinese adults reported they always washed hands before eating and after defaecation, and 30.0% (rural vs urban: 25.1% vs 32.8%) of adults always used soap or other sanitizers during washing. Using the criteria of 'always or very often washing hands with soap before eating and after defaecation without sharing a towel with family members after washing', only 47.2% (rural vs urban: 23.8% vs 59.1%) of the adults were graded to practice proper handwashing behaviour. Urban area, high level of education level, high level of knowledge about diseases, female gender and older age were protective factors for good hand hygiene; of these, area was found to be associated most strongly with handwashing behaviour. Adherence to an appropriate handwashing method and duration of handwashing are critical problems among Chinese adults. Area difference, level of education and level of knowledge of hand hygiene were most strongly associated with handwashing behaviour, and should be targeted in future health education.

Zhang, Jinshui; He, Chunyang; Zhou, Yuyu

2014-01-03

In this study, we developed a prior-knowledge-based spectral mixture analysis (PKSMA) to map impervious surfaces by using endmembers derived separately for high- and low-density urban regions. First, an urban area was categorized into high- and low-density urban areas, using a multi-step classification method. Next, in high-density urban areas that were assumed to have only vegetation and impervious surfaces (ISs), the Vegetation-Impervious model (V-I) was used in a spectral mixture analysis (SMA) with three endmembers: vegetation, high albedo, and low albedo. In low-density urban areas, the Vegetation-Impervious-Soil model (V-I-S) was used in an SMA analysis with four endmembers: high albedo, lowmore » albedo, soil, and vegetation. The fraction of IS with high and low albedo in each pixel was combined to produce the final IS map. The root mean-square error (RMSE) of the IS map produced using PKSMA was about 11.0%, compared to 14.52% using four-endmember SMA. Particularly in high-density urban areas, PKSMA (RMSE = 6.47%) showed better performance than four-endmember (15.91%). The results indicate that PKSMA can improve IS mapping compared to traditional SMA by using appropriately selected endmembers and is particularly strong in high-density urban areas.« less

Knowledge exchange processes in organizations and policy arenas: a narrative systematic review of the literature.

This article presents the main results from a large-scale analytical systematic review on knowledge exchange interventions at the organizational and policymaking levels. The review integrated two broad traditions, one roughly focused on the use of social science research results and the other focused on policymaking and lobbying processes. Data collection was done using systematic snowball sampling. First, we used prospective snowballing to identify all documents citing any of a set of thirty-three seminal papers. This process identified 4,102 documents, 102 of which were retained for in-depth analysis. The bibliographies of these 102 documents were merged and used to identify retrospectively all articles cited five times or more and all books cited seven times or more. All together, 205 documents were analyzed. To develop an integrated model, the data were synthesized using an analytical approach. This article developed integrated conceptualizations of the forms of collective knowledge exchange systems, the nature of the knowledge exchanged, and the definition of collective-level use. This literature synthesis is organized around three dimensions of context: level of polarization (politics), cost-sharing equilibrium (economics), and institutionalized structures of communication (social structuring). The model developed here suggests that research is unlikely to provide context-independent evidence for the intrinsic efficacy of knowledge exchange strategies. To design a knowledge exchange intervention to maximize knowledge use, a detailed analysis of the context could use the kind of framework developed here. © 2010 Milbank Memorial Fund.

Context: This article presents the main results from a large-scale analytical systematic review on knowledge exchange interventions at the organizational and policymaking levels. The review integrated two broad traditions, one roughly focused on the use of social science research results and the other focused on policymaking and lobbying processes. Methods: Data collection was done using systematic snowball sampling. First, we used prospective snowballing to identify all documents citing any of a set of thirty-three seminal papers. This process identified 4,102 documents, 102 of which were retained for in-depth analysis. The bibliographies of these 102 documents were merged and used to identify retrospectively all articles cited five times or more and all books cited seven times or more. All together, 205 documents were analyzed. To develop an integrated model, the data were synthesized using an analytical approach. Findings: This article developed integrated conceptualizations of the forms of collective knowledge exchange systems, the nature of the knowledge exchanged, and the definition of collective-level use. This literature synthesis is organized around three dimensions of context: level of polarization (politics), cost-sharing equilibrium (economics), and institutionalized structures of communication (social structuring). Conclusions: The model developed here suggests that research is unlikely to provide context-independent evidence for the intrinsic efficacy of knowledge exchange strategies. To design a knowledge exchange intervention to maximize knowledge use, a detailed analysis of the context could use the kind of framework developed here. PMID:21166865

The objective of this session is to foster a dialogue between experts working on global-scale, climate change and cities assessments in order to simultaneously present state-of-the-art knowledge on how cities are responding to climate change and to define emerging opportunities and challenges to the effective placement of this knowledge in the hands of local stakeholders and decision-makers. We will present the UCCRN and the Second UCCRN Assessment Report on Climate Change and Cities (ARC3-2), the second in an ongoing series of global, interdisciplinary, cross-regional, science-based assessments to address climate risks, adaptation, mitigation, and policy mechanisms relevant to cities. This is an especially important time to examine these issues. Cities continue to act as world leaders in climate action. Several major climate change assessment efforts are in full swing, at a crucial stage where significant opportunities for the co-production of knowledge between researchers and stakeholders exist. The IPCC AR5 Working Group II and III Reports have placed unprecedented attention on cities and urbanization and their connection to the issue of climate change. Concurrently several major, explicitly city-focused efforts have emerged from the Urban Climate Change Research Network (UCCRN), ICLEI, the Durban Adaptation Charter (DAC), C40, Future Earth, and the Urbanization and Global Environmental Change (UGEC) Project, among others. The underlying rationale for the discussion will be to identify methods and approaches to further foster the development and dissemination of new climate change knowledge and information that will be useful for cities, especially in small and medium-sized cities and in the developing country context where the demand is particularly acute. Participants will leave this session with: · The latest scientific data and state-of-the-knowledge on how cities are responding to climate change · Emerging opportunities and challenges to the effective placement of this knowledge in the hands of local stakeholders and decision-makers and for urban resilience and adaptation action · How practitioner-scientist interactions can work best · Synergies between the IPCC, ARC3, and other climate and cities assessments

Honey bees were trained to fly 400 m from their colony to an indoor laboratory foraging arena exposed to 2.45 GHz continuous wave microwaves at 5 power densities (0, 5, 10, 20, and 40 mW/cm/sup 2/). Foraging behavior did not differ from controls foraging within an unexposed sham arena in (1) number of round trips completed during a 3-h exposure session, (2) round trip time between the colony and the foraging arena, and (3) the length of time required to navigate the illuminated foraging arena. This study indicates that honey bees would not be adversely affected by foraging within amore » similar microwave field that would exist in future receiving antennae for the proposed solar power satellite energy transmission system in which power levels are expected to range from 23 mW/cm/sup 2/ at the antenna center to 1 mW/cm/sup 2/ at the edge.« less

Language of poverty strategies: Implemented in the urban elementary science classroom

2000-08-01

This research study reports the results of school-based staff development models used at three urban elementary schools that had liaison teachers assisting classroom teachers in implementing instructional strategies in science teaching from "Language of Poverty," a curriculum framework designed to address the academic needs of disadvantaged students. The case study of two urban elementary schools and six classroom teachers, and survey and interview data results of a third school, uncovered insights into several areas of science teaching in urban settings. One conclusion is that in spite of substantial allocation of resources and assistance, teachers did not translate instructional strategies from "Language of Poverty" curriculum into their classroom practices in a way that would foster urban disadvantaged students' understanding of "big science concepts." A second conclusion is that the school-based staff development models were limited in their ability to address the diverse professional needs of all of its staff. Third, as it relates to students, discipline issues occurred in these urban classrooms across ethnicity and gender. And in addition to teachers being knowledgeable of relevant social and cultural group norms' application of this knowledge in an appropriate and consistent manner is needed to effectively address discipline concerns.

This quantitative study examined the effectiveness of a geospatial curriculum approach to promote energy literacy in an urban school district and examined factors that may account for energy content knowledge achievement. An energy literacy measure was administered to 1,044 eighth-grade students (ages 13-15) in an urban school district in Pennsylvania, USA. One group of students received instruction with a geospatial curriculum approach (geospatial technologies (GT)) and another group of students received 'business as usual' (BAU) curriculum instruction. For the GT students, findings revealed statistically significant gains from pretest to posttest (p < 0.001) on knowledge of energy resource acquisition, energy generation, storage and transport, and energy consumption and conservation. The GT students had year-end energy content knowledge scores significantly higher than those who learned with the BAU curriculum (p < 0.001; effect size being large). A multiple regression found that prior energy content knowledge was the only significant predictor to the year-end energy content knowledge achievement for the GT students (p < 0.001). The findings support that the implementation of a geospatial curriculum approach that employs learning activities that focus on the spatial nature of energy resources can improve the energy literacy of urban middle-level education students.

To investigate providers' knowledge and attitudes about medical abortion (MA) and their views regarding the main challenges to expanding the use of MA in urban and rural areas in China. A total of 658 abortion providers were surveyed from November 7, 2009, to May 29, 2010. The providers' knowledge about MA was relatively poor, and most thought the risks of severe complications of MA were much higher than they are. Urban nonphysician providers were the least informed about MA. Most providers thought that the main challenges to an expanded use of MA were its lesser effectiveness in comparison to surgical abortion and women's lack of knowledge about it. In rural areas many providers thought that deficiencies of clinics, such as limited bed space and inadequate toilets and washing facilities, also posed serious obstacles to expanding MA use. Abortion providers, especially urban nonphysician providers, need refresher training to strengthen their knowledge of the approved protocol for providing MA in China, and also of the indications, contraindications, and safety and efficacy of the method. Deficiencies at abortion facilities should be addressed as well, and they are more numerous in rural areas. Copyright © 2012 International Federation of Gynecology and Obstetrics.

Background Unsafe injection practice can transmit various blood borne infections. The aim of this study was to assess the knowledge and practice of injection safety among injection providers, to obtain information about disposal of injectable devices, and to compare the knowledge and practices of urban and rural injection providers. Methods The study was conducted with injection providers working at primary health care facilities within Kaski district, Nepal. Ninety-six health care workers from 69 primary health care facilities were studied and 132 injection events observed. A semi-structured checklist was used for observing injection practice and a questionnaire for the survey. Respondents were interviewed to complete the questionnaire and obtain possible explanations for certain observed behaviors. Results All injection providers knew of at least one pathogen transmitted through use/re-use of unsterile syringes. Proportion of injection providers naming hepatitis/jaundice as one of the diseases transmitted by unsafe injection practice was significantly higher in urban (75.6%) than in rural (39.2%) area. However, compared to urban respondents (13.3%), a significantly higher proportion of rural respondents (37.3%) named Hepatitis B specifically as one of the diseases transmitted. Median (inter-quartile range) number of therapeutic injection and injectable vaccine administered per day by the injection providers were 2 (1) and 1 (1), respectively. Two handed recapping by injection providers was significantly higher in urban area (33.3%) than in rural areas (21.6%). Most providers were not aware of the post exposure prophylaxis guideline. Conclusion The knowledge of the injection providers about safe injection practice was acceptable. The use of safe injection practice by providers in urban and rural health care facilities was almost similar. The deficiencies noted in the practice must be addressed. PMID:27540325

Children nowadays, particularly in urban areas, are more disconnected from nature than ever before, leading to a large-scale "extinction of experience" with the natural world. Yet there are many potential benefits from children interacting with nature first-hand, including via outdoor learning opportunities. Urban environmental education programmes typically aim to increase awareness and knowledge of local biodiversity and to promote positive attitudes and behaviour towards the environment. However, limited research has been conducted evaluating to what extent these interventions achieve their goals. Here, we explore and assess the influence of a six-week bird-feeding and monitoring project conducted within school grounds ("Bird Buddies") on individual awareness, knowledge and attitudes towards birds by primary school children. This initiative was conducted across eight (sub-)urban primary schools within Brighton and Hove (UK), with 220 participating children (aged 7 to 10). Via pre- and post-project questionnaires, we found evidence for enhanced awareness of local biodiversity, alongside significant gains in both bird identification knowledge and attitudes, which were greatest for children with little prior exposure to nature. Many children expressed a keenness to continue improving the environmental value of their school grounds and to apply elements of the project at home. Student project evaluation scores were consistently positive. Mirroring this, participating teachers endorsed the project as a positive learning experience for their students. One year after the project, several schools were continuing to feed and watch birds. Collectively, the findings from this study highlight the multiple benefits that can be derived from engagement with a relatively short outdoor environmental activity. We therefore believe that such interventions, if repeated locally/longer term, could enhance children's experience with nature in urban settings with combined positive environmental impact.

Urban Planning by Le Corbusier According to Praxeological Knowledge

NASA Astrophysics Data System (ADS)

Dzwierzynska, Jolanta; Prokopska, Aleksandra

2017-12-01

The city is formed as a mosaic of various elements which affect its attractiveness. These elements range from location attributes, through economic opportunities, to social aspects. Therefore, urbanity and urban planning should be considered in a multi-dimensional context. In the paper we address the problem of urban planning by Le Corbusier according to praxeological and system knowledge. From praxeological point of view an active human being takes his/her choice between various possibilities by preferring one of these possibilities to the others, and by manifesting it by her actions. The same applies to the design process. Due to this fact, the scientific design process can be treated as a systematic rational reconstruction of the designer’s behaviour. Such a reconstruction requires previous reflection on designer’s work, as well as some consideration and design experience, thus know-how knowledge based on methodological knowledge. In the paper several city visions of Le Corbusier, as well as the characteristics and organisation of his design process are analysed. Le Corbusier’s innovative design ideas resulted from industrialisation changes and motorisation accelerating progress, which gave foundation to a new urban array. This array based on strict geometric forms, regularity and repetition determining standard. Thanks to his theories, Le Corbusier established principles of modern city construction and planning. Although some doubts were expressed as to the scale of centralisation of the cities designed by him and his class-based conception, he was awarded that overall welfare of the individual living in a city was the quality of built environment. Therefore, his designed creations were not only functional but they also produced emotions. The analysis of his prolific design activities allows us to state that the organisation of his architectural and urban planning process was very efficient and complex. The city concepts proposed by him were the subject of analysis by generations of designers. Also now, they can still be the basis for modelling virtual and navigable cities by modern planners. Le Corbusier’s comprehensive approach to modern city planning showed that research activities, that is theoretical thinking, and production activities, that is practice, are linked methodically. Therefore, urban planning should be understood not only as a projection of the possibilities of architecture, but as a multidisciplinary process. Due to this fact, an urban plan, as a result of that process, should be a synthesis of various social, industrial and economic aspects.

Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of potential determinants of tuberculosis (TB) knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. We found low knowledge of TB cause (26.7%); symptoms (46.8%), transmission (54.3%), prevention (34%) and free treatment (35%). Knowledge about TB treatment (69.4) and cure (85.1) was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI) lack of formal education (0.56; 0.38 - 0.83, P = 0.004), unemployment (0.67; 0.49 - 0.90, P = 0.010) and never testing for HIV (0.69; 0.51 - 0.92, P < 0.012). Whilst, older age (1.73; 1.30 - 2.29, P < 0.001) and residing in Lira (2.02; 1.50 - 2.72, P < 0.001) were independent determinants of higher knowledge of TB. This study revealed deficiencies in the public health knowledge about TB symptoms, diagnosis and treatment among urban-slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

The possibility of reconstituting the damaged heart has introduced a new paradigm in cardiovascular biology and created the potential for a new therapeutic approach in the cardiovascular field, where there is a compelling need for innovative treatments. While the results of animal and early clinical studies are encouraging, the more direct use of cell-based therapies in patients is still long-reached. Gaps in our basic understanding of mechanisms, lack of important randomized, double blind, and controlled clinical trials, as well as technology development for cell production are among challenges to be overcome before full translation of cell based therapies in clinical arena. This review focuses on summarizing the latest knowledge in stem cell therapy for cardiovascular diseases.

Mass gathering events in sports arenas create challenges regarding the cardiovascular safety of both athletes and spectators. A comprehensive medical action plan, to ensure properly applied cardiopulmonary resuscitation, and wide availability and use of automated external defibrillators (AEDs), is essential to improving survival from sudden cardiac arrest at sporting events. This paper outlines minimum standards for cardiovascular care to assist in the planning of mass gathering sports events across Europe with the intention of local adaptation at individual sports arenas, to ensure the full implementation of the chain of survival.

Canadian Residential Schools and Urban Indigenous Knowledge Production about Diabetes

2016-01-01

The construction of illness as an inscription on the body of colonization figures importantly among Indigenous community-based service and health care providers. While residential schools and diabetes have both been characterized as products of colonization, little work has been done to examine how they are connected to and informative for health provider practice. The research data presented in this article come from a collaborative urban Indigenous community-based study examining the legacy of negative relationships with food that was instilled in residential schools and used in diabetes intervention. I illustrate how residential school disciplined eating, providing a context for understanding the contemporary production of Indigenous health knowledge and practice in the urban setting, and the diet-related management of diabetes.

Drosophila melanogaster has become an important invertebrate model organism in biological and medical research, for mutational and genetic analysis, and in toxicological screening. Many screening assays have been developed that assess the flies' mortality, reproduction, development, morphology, or behavioral competence. In this study, we describe a new assay for locomotor competence. It comprises a circular walking arena with a lenticular floor and a flat cover (the slope of the floor increases gradually from the center to the edge of the arena) plus automated fly tracking and statistical analysis. This simple modification of a flat arena presents a graduated physical challenge, with which we can assess fine gradations of motor ability, since a fly's time average radial distance from the arena center is a direct indicator of its climbing ability. The time averaged distribution of flies as a function of slope, activity levels, and walking speed, yields a fine grained picture of locomotory ability and motivation levels. We demonstrate the strengths and weaknesses of this assay (compared with a conventional tap-down test) by observing flies treated with a neurotoxin (BMAA) that acts as a glutamate agonist. The assay proves well suited to detect dose effects and progression effects with higher statistical power than the traditional tap-down, but it has a higher detection limit, making it less sensitive to treatment effects. © 2012 WILEY PERIODICALS, INC.

Sibling competition arena: selfing and a competition arena can combine to constitute a barrier to gene flow in sympatry.

PubMed

Gibson, A K; Hood, M E; Giraud, T

2012-06-01

Closely related species coexisting in sympatry provide critical insight into the mechanisms underlying speciation and the maintenance of genetic divergence. Selfing may promote reproductive isolation by facilitating local adaptation, causing reduced hybrid fitness in parental environments. Here, we propose a novel mechanism by which selfing can further impair interspecific gene flow: selfing may act to ensure that nonhybrid progeny systematically co-occur whenever hybrid genotypes are produced. Under a competition arena, the fitness differentials between nonhybrid and hybrid progeny are then magnified, preventing development of interspecific hybrids. We investigate whether this "sibling competition arena" can explain the coexistence in sympatry of closely related species of the plant fungal pathogens (Microbotryum) causing anther-smut disease. The probabilities of intrapromycelial mating (automixis), outcrossing, and sibling competition were manipulated in artificial inoculations to evaluate their contribution to reproductive isolation. We report that both intrapromycelial selfing and sibling competition significantly reduced rates of hybrid infection beyond that expected based solely upon selfing rates and noncompetitive fitness differentials between hybrid and nonhybrid progeny. Our results thus suggest that selfing and a sibling competition arena can combine to constitute a barrier to gene flow and diminish selection for additional barriers to gene flow in sympatry. © 2012 The Author(s). Evolution © 2012 The Society for the Study of Evolution.

Traditional medicine for the rich and knowledgeable: challenging assumptions about treatment-seeking behaviour in rural and peri-urban Nepal

2016-01-01

Traditional medicine is commonly assumed to be a crucial health care option for poor households in developing countries. However, little research has been done in Asia to quantify the reliance on traditional medicine and its determinants. This research contributes to filling in this knowledge gap using household survey data collected from 571 households in three rural and peri-urban sites in Nepal in 2012. Questions encompassed household socioeconomic characteristics, illness characteristics, and treatment-seeking behaviour. Treatment choice was investigated through bivariate analyses. Results show that traditional medicine, and especially self-treatment with medicinal plants, prevail as treatment options in both rural and peri-urban populations. Contrarily to what is commonly assumed, high income is an important determinant of use of traditional medicine. Likewise, knowledge of medicinal plants, age, education, gender and illness chronicity were also significant determinants. The importance of self-treatment with medicinal plants should inform the development of health policy tailored to people’s treatment-seeking behaviour. PMID:26130610

Taking power, politics, and policy problems seriously: the limits of knowledge translation for urban health research.

PubMed

Murphy, Kelly; Fafard, Patrick

2012-08-01

Knowledge translation (KT) is a growing movement in clinical and health services research, aimed to help make research more relevant and to move research into practice and policy. This paper examines the conventional model of policy change presented in KT and assesses its applicability for increasing the impact of urban health research on urban health policy. In general, KT conceptualizes research utilization in terms of the technical implementation of scientific findings, on the part of individual decision-makers who can be "targeted" for a KT intervention, in a context that is absent of political interests. However, complex urban health problems and interventions infrequently resemble this single decision, single decision-maker model posited by KT. In order to clarify the conditions under which urban health research is more likely or not to have an influence on public policy development, we propose to supplement the conventional model with three concepts drawn from the social science: policy stages, policy networks, and a discourse analysis approach for theorizing power in policy-making.

Green infrastructure and ecosystem services – is the devil in the detail?

Cameron, Ross W. F.; Blanuša, Tijana

Background Green infrastructure is a strategic network of green spaces designed to deliver ecosystem services to human communities. Green infrastructure is a convenient concept for urban policy makers, but the term is used too generically and with limited understanding of the relative values or benefits of different types of green space and how these complement one another. At a finer scale/more practical level, little consideration is given to the composition of the plant communities, yet this is what ultimately defines the extent of service provision. This paper calls for greater attention to be paid to urban plantings with respect to ecosystem service delivery and for plant science to engage more fully in identifying those plants that promote various services. Scope Many urban plantings are designed based on aesthetics alone, with limited thought on how plant choice/composition provides other ecosystem services. Research is beginning to demonstrate, however, that landscape plants provide a range of important services, such as helping mitigate floods and alleviating heat islands, but that not all species are equally effective. The paper reviews a number of important services and demonstrates how genotype choice radically affects service delivery. Conclusions Although research is in its infancy, data are being generated that relate plant traits to specific services, thereby helping identify genotypes that optimize service delivery. The urban environment, however, will become exceedingly bland if future planting is simply restricted to monocultures of a few ‘functional’ genotypes. Therefore, further information is required on how to design plant communities where the plants identified (1) provide more than a single benefit (multifunctionality), (B) complement each other in maximizing the range of benefits that can be delivered in one location, and (3) continue to maintain public acceptance through diversity. The identification/development of functional landscape plants is an exciting and potentially high-impact arena for plant science. PMID:27443302

Adolescence is a crucial period in woman's life. The adolescent girls of today are the mothers of tomorrow in whose hand lie the future of her family, community and the nation. Because of the scarcity of information regarding the problems of adolescent girls, particularly in urban areas, the present study was undertaken to elicit information about the knowledge and practices regarding menstruation among adolescent girls. With this objective, a community-based cross-sectional study was done in an urban field practice area of BLDEA's Shri BM Patil Medical College, Bijapur. The study subjects included all adolescent girls who had attained menarche. Data was collected by questionnaire method and analysed. Out of 342 adolescent girls 324 (94.74%) were literate. Only 63 (18.42%) had knowledge about menstruation prior to attainment of menarche and this association was found to be statistically significant. The main source of information about menstruation was mother ie, 195 (57.01%). Nearly 81.58% adolescent girls were lacking knowledge about menstruation prior to menarche, this reflects upon the standard of awareness in the society to such important event and it also leads to negative reaction to menarche.

Background In Nicaragua, cervical cancer is the leading cause of cancer-related death for women ages 15–44, yet access to the HPV vaccine is limited to those with financial resources to pay for it. Cervical cytology is provided free of charge in public clinics; however, only 10% of women receive Pap smears at the nationally recommended frequency. Previous studies have not investigated how beliefs regarding cervical cancer screening may differ for urban and rural populations in Nicaragua. Furthermore, no investigation has assessed Nicaraguan women’s beliefs about a potential HPV immunization campaign. Given beliefs’ influence on health behavior, we investigated the structural, sociocultural, and knowledge-based factors influencing women’s beliefs regarding cervical cancer screening among urban and rural women in León, Nicaragua, and assessed acceptance of a potential HPV immunization program. Methods Our sequential explanatory mixed-methods study consisted of two phases: (1) a close-ended questionnaire, followed by (2) a qualitative, in-depth interview. Our quantitative sample contained 117 urban and 112 rural participants aged 18–49. We assessed beliefs regarding cervical cancer screening using a 22-item scale, with higher scores indicating screening-promoting beliefs in simple linear and multiple linear regressions. Twenty qualitative interviews, exploring the sociocultural dimensions of knowledge and attitudes indicated by our quantitative findings, were conducted with a sample of 13 urban and 7 rural women aged 19–46. Results The multiple linear regression indicates that greater knowledge of Pap smears, HPV, and cervical cancer is significantly associated with screening-promoting beliefs after adjusting for other relevant factors. There was no significant difference in screening knowledge and beliefs for urban and rural women. Four recurrent themes representing determinants of knowledge, beliefs, and attitudes regarding cervical cancer screening arose from interviews and built on quantitative findings: (1) women’s embarrassment due to the intimate nature of the Pap smear and male gender of exam provider discourages screening; (2) women believe Pap smears and cervical cancer are associated with sexual promiscuity, and this association stigmatizes women with the disease; (3) knowledge of cervical cancer prevention is limited to those who regularly attend health centers; and (4) women find screening inconvenient, believing understaffed clinics increase patient wait time, limit time patients spend with clinicians, and delay Pap results. A fifth theme indicates (5) participants’ acceptance of a potential HPV immunization program. Discussion Future interventions should focus on increasing access to information about cervical cancer prevention for women who do not regularly attend health centers. Furthermore, our results suggest that if funding were allocated to make the HPV vaccine accessible in Nicaragua, it would be well received. PMID:29085745

A common belief is that, unlike today, ancient urban areas developed in a sustainable way within the environmental limits of local natural resources and the ecosystem's capacity to respond. This long-held paradigm is based on a weak knowledge of the processes underpinning the emergence of urban life and the rise of an urban-adapted environment in and beyond city boundaries. Here, we report a 6000-year record of environmental changes around the port city of Akko (Acre), Israel, to analyse ecological processes and patterns stemming from the emergence and growth of urban life. We show that early urban development deeply transformed pre-existing ecosystems, swiftly leading to an urban environment already governed by its own ecological rules and this, since the emergence of the cities.

One application of gene flow science is the policy arena. In this article, we describe two examples in which the topic of gene flow has entered into the U.S. national environmental policymaking process: regulation of genetically engineered crops and clarification of the jurisdictional scope of the Clean Water Act. We summarize both current scientific understanding and the legal context within which gene flow science has relevance. We also discuss the process by which scientific knowledge has been synthesized and communicated to decision-makers in these two contexts utilizing the concept of 'boundary work'. Boundary organizations, the work they engage in to bridge the worlds of science, policy, and practice, and the boundary objects they produce to translate scientific knowledge existed in both examples. However, the specific activities and attributes of the objects produced varied based on the needs of the decision-makers. We close with suggestions for how scientists can contribute to or engage in boundary work with policymakers.

The surface urban heat island response to urban expansion: A panel analysis for the conterminous United States

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

Li, Xiaoma; Zhou, Yuyu; Asrar, Ghassem R.

Abstract: Urban heat island (UHI), a major concern worldwide, affects human health and energy use. With current and anticipated rapid urbanization, improved understanding of the response of UHI to urbanization is important for impact analysis and developing effective adaptation measures and mitigation strategies. Current studies mainly focus on a single or a few big cities and knowledge on the response of UHI to urbanization for large areas is very limited. Modelling UHI caused by urbanization for large areas that encompass multiple metropolitans remains a major scientific challenge/opportunity. As a major indicator of urbanization, urban area size lends itself well formore » representation in prognostic models to investigate the impacts of urbanization on UHI and the related socioeconomic and environmental effects. However, we have little knowledge on how UHI responds to the increase of urban area size, namely urban expansion, and its spatial and temporal variation over large areas. In this study, we investigated the relationship between surface UHI (SUHI) and urban area size in the climate and ecological context, and its spatial and temporal variations, based on a panel analysis of about 5000 urban areas of 10 km2 or larger, in the conterminous U.S. We found statistically significant positive relationship between SUHI and urban area size, and doubling the urban area size led to a SUHI increase of higher than 0.7 °C. The response of SUHI to the increase of urban area size shows spatial and temporal variations, with stronger SUHI increase in the Northern region of U.S., and during daytime and summer. Urban area size alone can explain as much as 87% of the variance of SUHI among cities studied, but with large spatial and temporal variations. Urban area size shows higher association with SUHI in regions where the thermal characteristics of land cover surrounding the urban are more homogeneous, such as in Eastern U.S., and in the summer months. This study provides a practical approach for large-scale assessment and modeling of the impact of urbanization on SUHI, both spatially and temporally, for developing mitigation/adaptation measures, especially in anticipated warmer climate conditions for the rest of this century.« less

Knowledge, adherence and control among patients with hypertension attending a peri-urban primary health care clinic, KwaZulu-Natal

PubMed Central

2017-01-01

Background Despite hypertension being a common condition among patients attending primary health care (PHC) clinics, blood pressure (BP) control is often poor. Greater insight into patient-related factors that influence the control of hypertension will assist in the development of an intervention to address the issues identified. Aim The aim of the study was to assess patient-related variables associated with hypertension control among patients attending a peri-urban PHC clinic. Setting The setting for this study was a peri-urban PHC clinic in KwaZulu-Natal. Method This was an observational, descriptive and cross-sectional study with 348 patients selected over a 1-month period. A validated questionnaire was used to collect data on patients’ hypertension knowledge and self-reported adherence, and BP recordings from their medical record were recorded to ascertain control. Results Of the 348 participants, only 49% had good BP control and 44% (152/348) had concurrent diabetes mellitus. The majority of patients had moderate levels of knowledge on hypertension and exhibited moderate adherence. There was a significant relationship between knowledge and reported adherence, between reported adherence and control, but not between reported knowledge and control. Conclusion Despite over 90% of the study population having moderate knowledge, and 62% with moderate reported adherence, BP was well controlled in only less than 50% of the study population. These findings suggest a need to emphasise adherence and explore new ways of approaching adherence. PMID:29113443

Connecting Water Quality With Air Quality Through Microbial Aerosols

NASA Astrophysics Data System (ADS)

Dueker, M. Elias

Aerosol production from surface waters results in the transfer of aquatic materials (including nutrients and bacteria) to air. These materials can then be transported by onshore winds to land, representing a biogeochemical connection between aquatic and terrestrial systems not normally considered. In urban waterfront environments, this transfer could result in emissions of pathogenic bacteria from contaminated waters. Despite the potential importance of this link, sources, near-shore deposition, identity and viability of microbial aerosols are largely uncharacterized. This dissertation focuses on the environmental and biological mechanisms that define this water-air connection, as a means to build our understanding of the biogeochemical, biogeographical, and public health implications of the transfer of surface water materials to the near-shore environment in both urban and non-urban environments. The effects of tidal height, wind speed and fog on coastal aerosols and microbial content were first quantified on a non-urban coast of Maine, USA. Culture-based, culture-independent, and molecular methods were used to simultaneously sample microbial aerosols while monitoring meteorological parameters. Aerosols at this site displayed clear marine influence and high concentrations of ecologically-relevant nutrients. Coarse aerosol concentrations significantly increased with tidal height, onshore wind speed, and fog presence. Tidal height and fog presence did not significantly influence total microbial aerosol concentrations, but did have a significant effect on culturable microbial aerosol fallout. Molecular analyses of the microbes settling out of near-shore aerosols provided further evidence of local ocean to terrestrial transport of microbes. Aerosol and surface ocean bacterial communities shared species and in general were dominated by organisms previously sampled in marine environments. Fog presence strengthened the microbial connection between water and land through air by increasing microbial aerosol settling rates and enhancing viability of aerosolized marine microbes. Using methods developed for the non-urban site, the role of local environment and winds in mediating water-air connections was further investigated in the urban environment. The local environment, including water surfaces, was an important source of microbial aerosols at urban sites. Large portions of the urban waterfront microbial aerosol communities were aquatic and, at a highly polluted Superfund waterfront, were closely related to bacteria previously described in environments contaminated with hydrocarbons, heavy metals, sewage and other industrial waste. Culturable urban aerosols and surface waters contained bacterial genera known to include human pathogens and asthma agents. High onshore winds strengthened this water-air connection by playing both a transport and production role. The microbial connection between water and air quality outlined by this dissertation highlights the need for information on the mechanisms that deliver surface water materials to terrestrial systems on a much larger scale. Moving from point measurements to landscape-level analyses will allow for the quantitative assessment of implications for this microbial water-air-land transfer in both urban and non-urban arenas.

Classification of Global Urban Centers Using ASTER Data: Preliminary Results From the Urban Environmental Monitoring Program

Stefanov, W. L.; Stefanov, W. L.; Christensen, P. R.

Land cover and land use changes associated with urbanization are important drivers of global ecologic and climatic change. Quantification and monitoring of these changes are part of the primary mission of the ASTER instrument, and comprise the fundamental research objective of the Urban Environmental Monitoring (UEM) Program. The UEM program will acquire day/night, visible through thermal infrared ASTER data twice per year for 100 global urban centers over the duration of the mission (6 years). Data are currently available for a number of these urban centers and allow for initial comparison of global city structure using spatial variance texture analysis of the 15 m/pixel visible to near infrared ASTER bands. Variance texture analysis highlights changes in pixel edge density as recorded by sharp transitions from bright to dark pixels. In human-dominated landscapes these brightness variations correlate well with urbanized vs. natural land cover and are useful for characterizing the geographic extent and internal structure of cities. Variance texture analysis was performed on twelve urban centers (Albuquerque, Baghdad, Baltimore, Chongqing, Istanbul, Johannesburg, Lisbon, Madrid, Phoenix, Puebla, Riyadh, Vancouver) for which cloud-free daytime ASTER data are available. Image transects through each urban center produce texture profiles that correspond to urban density. These profiles can be used to classify cities into centralized (ex. Baltimore), decentralized (ex. Phoenix), or intermediate (ex. Madrid) structural types. Image texture is one of the primary data inputs (with vegetation indices and visible to thermal infrared image spectra) to a knowledge-based land cover classifier currently under development for application to ASTER UEM data as it is acquired. Collaboration with local investigators is sought to both verify the accuracy of the knowledge-based system and to develop more sophisticated classification models.

To explore patient and provider perspectives regarding a new Web-based contraceptive support tool. We conducted a qualitative study at an urban Medicaid-based clinic among sexually active women interested in starting a new contraceptive method, clinic providers and staff. All participants were given the opportunity to explore Bedsider, an online contraceptive support tool developed for sexually active women ages 18-29 by the National Campaign to Prevent Teen and Unplanned Pregnancy and endorsed by the American Congress of Obstetricians and Gynecologists. Focus groups were conducted separately among patient participants and clinic providers/staff using open-ended structured interview guides to identify specific themes and key concepts related to use of this tool in an urban clinic setting. Patient participants were very receptive to this online contraceptive support tool, describing it as trustworthy, accessible and empowering. In contrast, clinic providers and staff had concerns regarding the Website's legitimacy, accessibility, ability to empower patients and applicability, which limited their willingness to recommend its use to patients. Contrasting opinions regarding Bedsider may point to a potential disconnect between how providers and patients view contraception information tools. Further qualitative and quantitative studies are needed to explore women's perspectives on contraceptive education and counseling and providers' understanding of these perspectives. This study identifies a contrast between how patients and providers in an urban clinic setting perceive a Web-based contraceptive tool. Given a potential patient-provider discrepancy in preferred methods and approaches to contraceptive counseling, additional research is needed to enhance this important arena of women's health care.

Exposure to nitrogen dioxide in an indoor ice arena - New Hampshire, 2011.

PubMed

2012-03-02

In January 2011, the New Hampshire Department of Health and Human Services (NHDHHS) investigated acute respiratory symptoms in a group of ice hockey players. The symptoms, which included cough, shortness of breath, hemoptysis, and chest pain or tightness, were consistent with exposure to nitrogen dioxide gas (NO), a byproduct of combustion. Environmental and epidemiologic investigations were begun to determine the source of the exposure and identify potentially exposed persons. This report summarizes the results of those investigations, which implicated a local indoor ice arena that had hosted two hockey practice sessions during a 24-hour period when the arena ventilation system was not functioning. A total of 43 exposed persons were interviewed, of whom 31 (72.1%) reported symptoms consistent with NO exposure. The highest attack rate was among the hockey players (87.9%). After repair of the ventilation system, no additional cases were identified. To prevent similar episodes, ice arena operators should ensure ventilation systems and alarms are operating properly and that levels of NO and carbon monoxide (CO) are monitored continuously for early detection of increased gas levels.

Keeping gay and bisexual men safe: The arena of HIV prevention science and praxis.

PubMed

Green, Adam Isaiah

2016-04-01

Abstract In this article, I draw from an ongoing ethnographic study of HIV prevention for gay, bisexual, and 'men who have sex with men' to develop an institutional analysis of HIV behavioral intervention science and praxis. I approach this analysis through the lens of the social worlds framework, focusing on the institutional arena in which HIV behavioral interventions are devised and executed. Toward this end, I focus on two fundamental points of contention that lie at the heart of the prevention enterprise and put its social organization in high relief: (1) conceptions of health and lifestyle practices and (2) attributions of expertise. These core contentions reveal less the steady advance of normal science than an arena of actors ensconced in boundary work and jurisdictional struggles over how to engineer behavior change and reduce the scale of the HIV epidemic. Their resolution, I argue, has occurred in a historically contingent process determined by the political economy of the US HIV prevention arena and the differential structural location of its social worlds.

Preparing Elementary Preservice Teachers for Urban Elementary Science Classrooms: Challenging Cultural Biases Toward Diverse Students

NASA Astrophysics Data System (ADS)

Moore, Felicia M.

2008-02-01

This study reports the learning of elementary preservice teachers regarding diversity and teaching science in diverse urban elementary classrooms. From participating in a semester-long book club, the preservice teachers reveal their cultural biases, connect and apply their knowledge of diversity, and understand that getting to know their students are important elements for teaching science in diverse classrooms. These 3 things connect in ways that allow the preservice teachers to understand how their cultural biases impede student learning and gain new knowledge of diversity as they change their cultural biases. Implications of this study reveal that preservice teachers need opportunities to reveal, confront, challenge, and change their cultural models and to develop new models for teaching science in urban elementary classrooms.

Urban lymphatic filariasis.

PubMed

Simonsen, Paul E; Mwakitalu, Mbutolwe E

2013-01-01

Lymphatic filariasis (LF) is a disabling and disfiguring disease resulting from a mosquito-borne parasitic infection. It is a major public health problem in many countries with a warm climate. Research and control activities have mainly focused on LF in rural areas where it also has its major impact. However, with rapid and unplanned growth of cities in the developing world, there is a need also to consider LF transmission and control in urban settings. Here, we review currently available knowledge on urban LF and the environmental and socio-economic basis for its occurrence. Among the three parasite species causing LF in humans, only Wuchereria bancrofti has been documented to have a significant potential for urban transmission. This is primarily because one of its vectors, Culex quinquefasciatus, thrives and proliferates excessively in crowded city areas with poor sanitary, sewerage and drainage facilities. For this reason, urban LF also often shows a marked focality in distribution, with most cases clustered in areas inhabited by the less privileged city populations. More knowledge on urban LF is needed, in particular on its socio-economic and human behavioural context, on the potential for transmission in regions where other LF vector species predominate, and on rapid methods for identification and mapping of risk areas, to provide a strong evidence base for its control.

Since Namibia's Independence in 1990, the population of elders--persons 65 years old and older--in urban communities is growing steadily. As such, requests for home health care, health counselling, respite care and residential care for aging members of society are overwhelming nurses and the health care system. This study expands transcultural nursing knowledge by increasing understanding of generic (home-based) patterns of elder care that are practised and lived by urban Namibian families. Guided by Madeleine Leininger's theory of culture care diversity and universality and the ethnonursing research method, emic (insider) meanings and expressions of care and caring for elders in selected urban households have been transposed into five substantive themes. The themes, which depict what carring for elders means to urban families, include: 1 nurturing the health of the family, 2 trusting in the benevolence of life as lived, 3 honouring one's elders, 4 sustaining security and purpose for life amid uncertainty, and 5 living with rapidly changing cultural and social structures. These findings add a voice from the developing world to the evolving body of transcultural nursing knowledge. Synthesis of findings with professional care practices facilitates the creation of community-focussed models for provisioning culturally congruent nursing care to elders and their families in urban Namibia.

With the influx of rural migrants into urban areas, the spread of HIV has increased significantly in Shaanxi Province (China). Migrant workers are at high risk of HIV infection due to social conditions and hardships (isolation, separation, marginalization, barriers to services, etc.). We explored the efficacy of a HIV/AIDS prevention and control program for rural migrants in Shaanxi Province, administered at both rural and urban sites. Guidance concerning HIV/AIDS prevention was given to the experimental group (266 migrants) for 1 year by the center of disease control, community health agencies and family planning department. The intervention was conducted according to the HIV/AIDS Prevention Management Manual for Rural Migrants. A control group of migrants only received general population intervention. The impact of the intervention was evaluated by administering HIV/AIDS knowledge, attitudes and sexual behavior (KAB) questionnaires after 6 and 12 months. In the experimental group; 6 months of intervention achieved improvements in HIV/AIDS related knowledge. After 12 months; HIV/AIDS-related knowledge reached near maximal scores. Attitude and most behaviors scores were significantly improved. Moreover; the experimental group showed significant differences in HIV-AIDS knowledge; attitude and most behavior compared with the control group. The systematic long-term cross-site HIV/AIDS prevention in both rural and urban areas is a highly effective method to improve HIV/AIDS KAB among rural migrants.

Hepatitis C Virus: Patients' Risk Factors and Knowledge in an Urban Clinic Providing Wound Care.

Pieper, Barbara; Sickon, Katharine

2018-03-01

Affecting about 3.2 million people in the United States, hepatitis C virus (HCV) is the primary cause of chronic liver disease and a global health challenge. Hepatitis C virus can affect the functioning of the liver, the health of the person, and thus wound healing. This quality project explores risk factors of HCV; self-reported screening, occurrence, and treatment; and knowledge of HCV in patients seeking wound care in an urban clinic. Demographic risk factors, HCV history, and responses to a 22-item true-false-don't know HCV Knowledge Test were obtained from 58 patients. Risk factors included age (mean, 61.07 years), male sex (n = 41), non-Hispanic black race/ethnicity (n = 51), and history of injection drugs (n = 38). Thirty-nine (67.2%) stated they had been screened for HCV; 31 were told they were infected. Only 14 went to a clinic for HCV care and 11 reported they were treated. The mean number of correct answers on the HCV Knowledge Test was 14.4 (standard deviation, 5.7). This urban clinic had patients with multiple HCV risk factors; they often lacked HCV screening and/or referral for treatment. Their HCV knowledge was generally low. As a major public health problem that could impact wound healing, wound care practitioners should ask patients about their HCV status, encourage HCV screening and care, and provide HCV information.

Shape shifting: Local landmarks interfere with navigation by, and recognition of, global shape.

PubMed

Buckley, Matthew G; Smith, Alastair D; Haselgrove, Mark

2014-03-01

An influential theory of spatial navigation states that the boundary shape of an environment is preferentially encoded over and above other spatial cues, such that it is impervious to interference from alternative sources of information. We explored this claim with 3 intradimensional-extradimensional shift experiments, designed to examine the interaction of landmark and geometric features of the environment in a virtual navigation task. In Experiments 1 and 2, participants were first required to find a hidden goal using information provided by the shape of the arena or landmarks integrated into the arena boundary (Experiment 1) or within the arena itself (Experiment 2). Participants were then transferred to a different-shaped arena that contained novel landmarks and were again required to find a hidden goal. In both experiments, participants who were navigating on the basis of cues that were from the same dimension that was previously relevant (intradimensional shift) learned to find the goal significantly faster than participants who were navigating on the basis of cues that were from a dimension that was previously irrelevant (extradimensional shift). This suggests that shape information does not hold special status when learning about an environment. Experiment 3 replicated Experiment 2 and also assessed participants' recognition of the global shape of the navigated arenas. Recognition was attenuated when landmarks were relevant to navigation throughout the experiment. The results of these experiments are discussed in terms of associative and non-associative theories of spatial learning.

Modeling Novelty Habituation During Exploratory Activity in Drosophila

PubMed Central

Soibam, Benjamin; Shah, Shishir; Gunaratne, Gemunu H.; Roman, Gregg W.

2013-01-01

Habituation is a common form of non-associative learning in which the organism gradually decreases its response to repeated stimuli. The decrease in exploratory activity of many animal species during exposure to a novel open field arena is a widely studied habituation paradigm. However, a theoretical framework to quantify how the novelty of the arena is learned during habituation is currently missing. Drosophila melanogaster display a high mean absolute activity and a high probability for directional persistence when first introduced to a novel arena. Both measures decrease during habituation to the arena. Here, we propose a phenomenological model of habituation for Drosophila exploration based on two principles: Drosophila form a spatial representation of the arena edge as a set of connected local patches, and repeated exposure to these patches is essential for the habituation of the novelty. The level of exposure depends on the number of visitations and is quantified by a variable referred to as “coverage.” This model was tested by comparing predictions against the experimentally measured behavior of wild type Drosophila. The novelty habituation of wild type Canton-S depends on coverage and is specifically independent of the arena radius. Our model describes the time dependent locomotor activity, ΔD, of Canton-S using an experimentally established stochastic process Pn(ΔD) which depends on the coverage. The quantitative measures of exploration and habituation were further applied to three mutant genotypes. Consistent with a requirement for vision in novelty habituation, blind no receptor potential A7 mutants display a failure in the decay of probability for directional persistence and mean absolute activity. The rutabaga2080 habituation mutant also shows defects in these measures. The kurtz1 non-visual arrestin mutant demonstrates a rapid decay in these measures, implying reduced motivation. The model and the habituation measures offer a powerful framework for understanding mechanisms associated with open field habituation. PMID:23597866

The objective of the study was to assess nutritional and health status as well as nutritional knowledge in urban middle-aged Malaysian women. The impact of menopause on diet and health indices was also studied. The study included 360 disease free women, non users of HRT,aged > or =45 years with an intact uterus recruited from November 1999 to October 2001. Personal characteristics, anthropometric measurements and blood sample were acquired followed by clinical examination. Nutrient intake and nutritional knowledge was determined by a quantitative FFQ and KAP. The findings showed that urban middle-aged women, aged 51.65+/-5.40 years had energy intakes (EI) 11% below RDA, consisting of 53% carbohydrates, 15% protein and a 32% fat which declined with age. The sample which comprised of 42.5% postmenopausal women had a satisfactory diet and healthy lifestyle practices. Premenopausal women consumed more dietary fat (6%) with other aspects of diet comparable to the postmenopausal women. Iron intake was deficient in premenopausal women, amounting to 56% RDA contributing to a 26% prevalence of anaemia. Overall, calcium intake reached 440 mg daily but dairy products were not the main source. The postmenopaused had a more artherogenic lipid profile with significantly higher total cholesterol (TC) and LDL-C, but more premenopausal women were overweight/obese (49% versus 35%). EI was the strongest predictor for BMI and waist circumference (WC), with WC itself an independent predictor of fasting blood sugar and TC with BMI strongly affecting glucose tolerance. High nutritional knowledge was seen in 39% whereas 20% had poor knowledge. Newspapers and magazines, followed by the subject's social circle, were the main sources of nutritional information. Nutritional knowledge was positively associated with education, household income, vitamin/ mineral supplementation and regular physical activity but inversely related to TC. In conclusion, middle-aged urban women had an adequate diet with low iron and calcium intakes. Nutritional knowledge was positively associated to healthier lifestyle practices and lower TC. A comparable nutrient intake and lifestyle between pre and postmenopausal women suggested that health changes associated with menopause was largely independent of diet.

2013-01-01

Obstetric fistula is a sequela of complicated labour, which, if untreated, leaves women handicapped and socially excluded. In Burkina Faso, incidence of obstetric fistula is 6/10,000 cases amongst gynaecological patients, with more patients affected in rural areas. This study aims to evaluate knowledge on obstetric fistula among young women in a health district of Burkina Faso, comparing rural and urban communities. This cross-sectional study employed multi-stage sampling to include 121 women aged 18-20 years residing in urban and rural communities of Boromo health district. Descriptive statistics and multiple logistic regression analysis were used to compare differences between the groups and to identify predictors of observed knowledge levels. Rural women were more likely to be married (p<0.000) and had higher propensity to teenage pregnancy (p=0.006). The survey showed overall poor obstetric fistula awareness (36%). Rural residents were less likely to have adequate preventive knowledge than urban residents [OR=0.35 (95%-CI, 0.16–0.79)]. This effect was only slightly explained by lack of education [OR=0.41 (95%-CI, 0.18–0.93)] and only slightly underestimated due to previous pregnancy [OR=0.27 (95%-CI, 0.09–0.79)]. Media were the most popular source of awareness amongst urban young women in contrast to their rural counterparts (68% vs. 23%). Most rural young women became ‘aware’ through word-of-mouth (68% vs. 14%). All participants agreed that the hospital was safer for emergency obstetric care, but only 11.0% believed they could face pregnancy complications that would require emergency treatment. There is urgent need to increase emphasis on neglected health messages such as the risks of obstetric fistula. In this respect, obstetric fistula prevention programs need to be adapted to local contexts, whether urban or rural, and multi-sectoral efforts need to be exerted to maximise use of other sectoral resources and platforms, including existing routine health services and schools, to ensure sustainability of health literacy efforts.

2012-12-01

The lack of community awareness about rabies control is a major issue that thwarts efforts to prevent human deaths caused by rabies. The objectives of this study were (1) to assess community knowledge and attitudes about rabies, rabies prevention and stray dog control in an urban slum community and (2) to determine the factors that influence rabies awareness in urban slums. Using a systematic random sampling strategy, 185 participants were selected from 8 urban slums. The data were collected by direct interview using a pre-tested, structured questionnaire. In the study population, 74.1% of the participants had heard about rabies, and 54.1% knew that rabies is a fatal disease. Only 33.5% of the interviewees felt that people in the community had a role to play in controlling the stray dog population. Gender, age and educational status were significantly associated with rabies awareness. Our study indicates that there are gaps in the knowledge and attitudes of individuals living in urban slums regarding rabies prevention and control. Efforts to promote awareness should be targeted at men, older people and uneducated individuals. Copyright © 2012 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd.

Background & objectives There is poor knowledge and behaviors regarding chronic diseases related nutritional and lifestyle factors among women in low income countries. To evaluate efficacy of a multilevel population-based intervention in improving knowledge and practices for related factors we performed a study in India. Methods Population based study among women 35–70 years was performed in four urban and five rural locations. Stratified sampling was performed and we enrolled 4624 (rural 2616, urban 2008) of eligible 8000 women (58%). Demographic details, medical history, diet, physical activity and anthropometry were recorded and blood hemoglobin, glucose and total cholesterol determined. Knowledge and behaviors regarding diet in chronic diseases were inquired in a randomly selected 100 women at each site (n = 900). A systematic multilevel population based intervention (using posters, handouts, street plays, public lectures, group lectures and focused group discussions) was administered over 6 months at each site. The questionnaire was re-administered at the end in random 100 women (n = 900) and differences determined. Descriptive statistics are reported. Comparison of parameters before and after intervention was assessed using Mann Whitney test. Results Prevalence (%) of chronic disease related lifestyles and risk factors in rural/urban women, respectively, was illiteracy in 63.6/29.4, smoking/tobacco use 39.3/18.9, high fat intake 93.6/93.4, high salt intake 18.2/12.6, low physical activity 59.5/70.2, overweight/obesity 22.5/45.6, truncal obesity 13.0/44.3, hypertension 31.6/48.2, hypercholesterolemia 13.5/27.7, and diabetes in 4.3/15.1 percent. Composite chronic diseases knowledge at baseline vs after intervention increased significantly in overall (32.0 vs 62.0), rural (29.0 vs 63.5) and urban (39.5 vs 60.5) groups (p < 0.001). Significant increase in knowledge regarding diet in hypertension, diabetes, heart disease and anemia as well as importance of dietary proteins, fats, fibres and fruits was observed (p < 0.001). There was insignificant change in most of the practices regarding intake of low fat, high protein, high fibre diet except sieving the flour which declined significantly (80.1 vs 53.6, p < 0.001). Conclusions A short-term multilevel population-wide intervention among women in rural and urban locations in India increased chronic disease knowledge but failed to influence practices.

2018-02-01

The objective of this study was to explore the concept of mindset for psychiatrists who are considering stepping into the leadership arena. Qualitative themes were extracted from dialogue on leadership development at a Royal Australian and New Zealand College of Psychiatrists forum for early career psychiatrists. Three key themes were identified: adapting to a professional identity as psychiatrists; developing a mindset for leadership; and acting intentionally to seek opportunities for leadership. Shifts in professional identity occur in the transition from trainee to specialist as early career psychiatrists become increasingly aware of broad systemic factors in clinical care. The concept of a mindset, distinct from a skillset of knowledge and expertise, may be an emergent quality for psychiatrists who are seeking to develop their leadership potential.

To be or not IP? Exploring limits within patent law for the constitutionalization of intellectual property rights and the governance of synthetic biology in human health.

PubMed

Schneider, Ingrid

2012-01-01

The article explores limits within patent law for the constitutionalization of Intellectual Property Rights and the governance of synthetic biology in human health. To this end, it starts by explaining the inherent rationales of two fundamental limits within European patent law, namely (1) the boundary between discovery and invention (Art. 52 EPC); (2) the ordre public and public policy clause (Art. 53 (a) EPC). Both these exclusions from patent eligibility bear a normative function but rely on opposing inherent logics, functions, and regulatory aims. While in the first type of logics, "enabling access for all" is the guiding principle, in the second, converse logics, no one should have access to the technological knowledge in question. The second part contends that decisions on whether and how to grant patents in synthetic biology are not independent from institutional frameworks: The arena in which synthetic biology patenting will be dealt with will be decisive for whether and how boundaries will be deployed. From a political science perspective, the administrative, legislative and judicial arena can be distinguished. If synthetic biology will be negotiated in the legislative arena, in particular in the European Parliament, the probabilities will be higher that either the discovery clause or the ordre public clause will be applied. In contrast, patent offices and courts have, at least in the past decades, employed a narrow interpretation of these absolute exemptions from patentability and hardly ever used them. The third part asserts that metaphoric framing of synthetic biology is another crucial factor for patentability questions. Semantic framing may relate to the articulation and mobilization of consent or dissent, and thus public acceptance of synthetic biology. Whether applications of synthetic biology are conceived as "natural" or "synthetic" DNA may have an influence on whether patenting might become contested as "patenting life" or accepted as novel, and also on passing the inventive step and industrial application tests. Proceeding in such a manner can be regarded as "upstreaming" ethics, anticipatory impact assessment, and policy analysis in the biosciences and as a tool for constitutionalizing intellectual property rights.

2010-01-01

The American Association of Colleges of Nursing in collaboration with leaders in the health care arena has developed a new role in nursing, the clinical nurse leader (CNL). The CNL is a master's-prepared advanced nurse generalist, accountable for providing high-quality, cost-effective care for a cohort of patients in a specific microsystem. Although initial implementation of the CNL has been predominantly in urban acute care settings, the skill set of the CNL role is equally applicable to diverse clinical settings, such as smaller rural hospitals, home-based home care providers, long-term care facilities, schools, Veteran's Administration facilities, and public health settings. This article reports the strategies used and the progress made at The University of Alabama Capstone College of Nursing in the development of innovative partnerships to develop the role of the CNL in diverse clinical settings. With academia and practice working in partnership, the goal of transforming health care and improving patient outcomes can be achieved. Copyright © 2010 Elsevier Inc. All rights reserved.

To test the feasibility and effectiveness of social marketing on the improvement of women's knowledge, attitudes, and behaviors regarding iron-fortified soy sauce (FeSS). A community-based intervention was conducted among 4 groups, experimental rural (E(R)), control rural (C(R)), experimental urban (E(U)), and control urban (C(U)). Urban and rural areas in Guizhou province, China. Women 19 to 70 years old (n = 193 in rural areas and n = 179 in urban areas). A mass-media campaign to promote use of FeSS was conducted throughout Guizhou province. In the intervention areas, social marketing strategies using integrated 6 Ps (product, price, place, promotion, policy, and partnership) were implemented from December 2004 to February 2006. Knowledge of FeSS; benefits, barriers, and intention to purchase; availability of FeSS; behaviors regarding purchase and use of FeSS. Analysis of covariance, paired T test and cross-tabulations were used. The alpha level was set at .05. Compared with the baseline, perceived benefits of FeSS, barriers (BARRI) and intention to buy (INTEN) significantly improved within both experimental groups (P < .01 or .001). The only improvement in control groups was for BARRI in C(R) (P < .001). Availability of FeSS increased in all areas. Purchase and use of FeSS in rural and urban intervention groups increased by nearly 30% more than those in control groups. Social marketing of FeSS is feasible and effective to improve knowledge, perception (perceived benefits and overcoming barriers), intention to purchase, and consumption of FeSS among women in Guizhou, China.

Although the link between social factors and health-related outcomes has long been widely acknowledged, the mechanisms characterizing this link are relatively less known and remain a subject of continued investigation across disciplines. In this study, drawing on the structural influence model of health communication, the hypothesis that differences in concern about and information needs on HIV/AIDS, HIV/AIDS-related media use, and perceived salience of HIV/AIDS-related information, characterized as communication inequality, can at least partially mediate the impacts of socioecological (urban vs. rural) and socioeconomic (education) disparities on inequalities in HIV/AIDS knowledge and risk perception was tested. Data were collected from a random sample of 986 urban and rural respondents in northwest Ethiopia. Structural equation modeling, using the maximum likelihood method, was used to test the mediation models. The models showed an adequate fit of the data and hence supported the hypothesis that communication inequality can at least partially explain the causal mechanism linking socioeconomic and socioecological factors with HIV/AIDS knowledge and risk perception. Both urbanity versus rurality and education were found to have significant mediated effects on HIV/AIDS knowledge (urbanity vs. rurality: β = 0.28, p = .001; education: β = 0.08, p = .001) and HIV/AIDS risk perception (urbanity vs. rurality: β = 0.30, p = .001; education: β = 0.09, p = .001). It was concluded that communication inequality might form part of the socioecologically and socioeconomically embedded processes that affect HIV/AIDS-related outcomes. The findings suggest that the media and message effects that are related to HIV/AIDS behavior change communication can be viewed from a structural perspective that moves beyond the more reductionist behavioral approaches upon which most present-day HIV/AIDS communication campaigns seem to be based.

Birds in the playground: Evaluating the effectiveness of an urban environmental education project in enhancing school children’s awareness, knowledge and attitudes towards local wildlife

Children nowadays, particularly in urban areas, are more disconnected from nature than ever before, leading to a large-scale “extinction of experience” with the natural world. Yet there are many potential benefits from children interacting with nature first-hand, including via outdoor learning opportunities. Urban environmental education programmes typically aim to increase awareness and knowledge of local biodiversity and to promote positive attitudes and behaviour towards the environment. However, limited research has been conducted evaluating to what extent these interventions achieve their goals. Here, we explore and assess the influence of a six-week bird-feeding and monitoring project conducted within school grounds (“Bird Buddies”) on individual awareness, knowledge and attitudes towards birds by primary school children. This initiative was conducted across eight (sub-)urban primary schools within Brighton and Hove (UK), with 220 participating children (aged 7 to 10). Via pre- and post-project questionnaires, we found evidence for enhanced awareness of local biodiversity, alongside significant gains in both bird identification knowledge and attitudes, which were greatest for children with little prior exposure to nature. Many children expressed a keenness to continue improving the environmental value of their school grounds and to apply elements of the project at home. Student project evaluation scores were consistently positive. Mirroring this, participating teachers endorsed the project as a positive learning experience for their students. One year after the project, several schools were continuing to feed and watch birds. Collectively, the findings from this study highlight the multiple benefits that can be derived from engagement with a relatively short outdoor environmental activity. We therefore believe that such interventions, if repeated locally/longer term, could enhance children’s experience with nature in urban settings with combined positive environmental impact.

Despite the growing number of rural-urban migrant children in China, follow-up observation on the oral health of migrant children is still scarce. This study described the changes of oral health knowledge, behaviors and parental practices in migrant children over a period of one year. Possible factors affecting changes were also investigated. The study used purposive sampling to select five private schools of migrant children in Guangzhou. A total of 1900 students in Grades 3 and 4 were recruited. A self-administered questionnaire was used in November 2011 to understand their basic situations, including oral health knowledge, behaviors and parental practices. A final survey was conducted in April 2013 to detect any changes. The mean accuracy of oral health knowledge was 53.17% and 59.42% in 2011 and 2013, respectively (p < 0.001). For migrant children, the total score of oral hygiene, dietary habits and parental practices increased at the follow-up evaluation (p < 0.05). Children with less oral health knowledge were more likely to achieve significantly positive changes in score of knowledge (p < 0.001) in the final survey. Migrant children who had worse performance on oral hygiene (beta estimate = 0.68, p < 0.001), dietary habits (beta estimate = 0.58, p < 0.001) and good parental practices in the baseline survey were more likely to obtain beneficial changes. No significant associations between demographic characteristics and changes of oral health knowledge and behaviors (p > 0.05) were observed. Oral health knowledge, behaviors and parental practices among migrant children significantly improved at the follow-up assessment. However, the overall situation was still poor. Positive and effective health education and prevention programs tailored to rural-urban migrant children with varying levels of oral health knowledge, behaviors and parental practices will be needed.

Socio-demographic determinants and prevalence of Tuberculosis knowledge in three slum populations of Uganda

PubMed Central

2012-01-01

Background Knowledge of tuberculosis has been shown to influence health seeking behaviour; and urban slum dwellers are at a higher risk of acquiring tuberculosis than the general population. The study aim was to assess knowledge of tuberculosis and identify the associated socio-demographic determinants, in order to inform tailored interventions for advocacy, communication and social mobilisation in three urban-slum communities of Uganda. Methods A cross-sectional survey of 1361 adults between April and October 2011. Data was analyzed by descriptive statistics. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of potential determinants of tuberculosis (TB) knowledge were estimated by multivariable ordinal logistic regression using Stata 11.2 software. Results We found low knowledge of TB cause (26.7%); symptoms (46.8%), transmission (54.3%), prevention (34%) and free treatment (35%). Knowledge about TB treatment (69.4) and cure (85.1) was relatively high. Independent determinants of poor knowledge of TB in the multivariable analysis included (aOR, 95% CI) lack of formal education (0.56; 0.38 – 0.83, P = 0.004), unemployment (0.67; 0.49 – 0.90, P = 0.010) and never testing for HIV (0.69; 0.51 – 0.92, P < 0.012). Whilst, older age (1.73; 1.30 – 2.29, P < 0.001) and residing in Lira (2.02; 1.50 – 2.72, P < 0.001) were independent determinants of higher knowledge of TB. Conclusion This study revealed deficiencies in the public health knowledge about TB symptoms, diagnosis and treatment among urban-slum dwellers in Uganda. Tuberculosis control programmes in similar settings should consider innovative strategies for TB education, advocacy, communication and social mobilisation to reach the youth, unemployed and less-educated; as well as those who have never tested for HIV.

A crowdsourcing study supported by a public participation GIS tool was designed and carried out in two Norwegian regions. The aim was to improve the knowledge about emissions from wood burning for residential heating in urban areas based on the collection of citizens' localized insights. We focus on three main issues: 1) type of dwelling and residential heating source; 2) wood consumption and type of wood appliances; and 3) citizens' perception of the urban environment. Our study shows the importance of wood burning for residential heating, and of the resulted particle emissions, in Norwegian urban areas. Citizens' localized insights on environmental perception highlight the areas in the city that require particular attention as part of clean air strategies. Information about environmental perception is combined with existing environmental data showing certain correlation. The results support the urban environmental management based on co-benefit approaches, achieving several outcomes from a single policy measure. Measures to reduce urban air pollution will have a positive impact on the citizens' environmental perception, and therefore on their quality of life, in addition to reducing the negative consequences of air pollution on human health. The characterization of residential heating by fuelwood is still a challenging activity. Our study shows the potential of a crowdsourcing method as means for bottom-up approaches designed to increase our knowledge on human activities at urban scale that result on emissions.

Lambrecht, Susan C.; Mahieu, Stephanie; Cheptou, Pierre-Olivier

2016-11-01

Current rates of urbanization are creating new opportunities for studying urban plant ecology, but our knowledge of urban plant physiology lags behind that of other ecosystems. Moreover, higher temperatures, elevated CO2, and increased inorganic nitrogen deposition along with altered moisture regimes of urban as compared to rural areas creates a compelling analog for studying adaptations of plants to climate change. We grew plants under common conditions in a greenhouse to determine whether populations of Crepis sancta (Asteraceae) differed in phenological, morphological, and physiological traits. We also used a field experiment to test for natural selection on these traits in urban Montpellier, France. Urban plants flowered and senesced later than rural plants, and natural selection favored later phenology in the urban habitat. Natural selection also favored larger plants with more leaves, and increased photosynthesis and leaf nitrogen concentration. Ours is the first study to document selection on plant functional traits in an urban habitat and, as such, advances our understanding of urban plant ecology and possible adaptations to climate change.

The population's attitude towards smoking bans in public arenas is important for their passing, implementation and compliance. Smoking bans are believed to reduce the social acceptability of smoking, and once people experience them, public support increases--also among pre-ban sceptics. This study aimed to examine the temporal changes in public attitude towards smoking bans in public arenas from 2007 to 2010 and whether these changes differed across educational attainment, smoking status and intention to quit among smokers. Data from two surveys among adults (aged 25-79 years) in 2007 and 2010 in the Capital Region of Denmark (n=36,472/42,504, response rate = 52.3) was linked with data on sex, age and educational attainment from central registers. Age-standardised prevalence of supportive attitude towards smoking bans was estimated. Temporal changes in supportive attitude were explored in workplaces, restaurants and bars using logistic regression models. The prevalence of supportive attitude towards smoking bans increased significantly in all arenas from 2007 to 2010. Positive temporal changes in supportive attitude towards smoking bans were seen across educational attainment, smoking status and intention to quit smoking in restaurants and across smoking status for smoking bans in workplaces and bars. The results of this study show that the public's attitude towards smoking in public arenas has changed after the implementation of a comprehensive smoking ban. This change in attitude can support implementation of future legislation on smoking and may lead to positive changes in smoking norms. © 2014 the Nordic Societies of Public Health.

What Roles Can Scientists Play in Public Discourse?

What is a useful and proper role for scientists in the public arena? How can we best discriminate where the boundary lies between expert knowledge and values or political opinion, and how can we properly honor that line? What can we expect in the way of reception for our interventions, and how can we increase their efficacy? Involvement in public policy debates is a common and accepted role for scientists in many disciplines. In the sciences related to public health, it is taken for granted that experts will talk about the implications of their research for public policy, whether in regard to smoking, diet, or disease spread. There is also a remarkable track record of geoscientists taking a lead role in the public arena and actually affecting public policy—F. Sherwood Rowland and Mario Molina collaborated on ozone depletion research at the Department of Chemistry at University of California, Irvine and then went on to make outstanding public contributions, as have James Hansen (at NASA's Goddard Institute for Space Studies); Robert Watson (first at NASA, then at the University of East Anglia); and, of course, the late Stephen Schneider (first at the U.S. National Center for Atmospheric Research, then Stanford) on climate. Some “public” geoscientists have restricted their activities to interpreting science for the wider public, while others have endorsed specific policy initiatives (see Figure 1). I firmly believe that the quality of public discourse and the information reaching policy makers were better for their interventions.

Quantitative assessment of urban thermal environment has become a focus for urban climate and environmental science since the concept of urban heat island has been proposed. With the continual development of space information and computer simulation technology, substantial progresses have been made on quantitative assessment techniques and methods of urban thermal environment. The quantitative assessment techniques have been developed to dynamics simulation and forecast of thermal environment at various scales based on statistical analysis of thermal environment on urban-scale using the historical data of weather stations. This study reviewed the development progress of ground meteorological observation, thermal infrared remote sensing and numerical simulation. Moreover, the potential advantages and disadvantages, applicability and the development trends of these techniques were also summarized, aiming to add fundamental knowledge of understanding the urban thermal environment assessment and optimization.

We utilized a participatory mapping approach to collect point locations, photographs, and descriptive data about select built environment stressors identified and prioritized by community residents living in the Proctor Creek Watershed, a degraded, urban watershed in Northwest Atlanta, Georgia. Residents (watershed researchers) used an indicator identification framework to select three watershed stressors that influence urban livability: standing water, illegal dumping on land and in surface water, and faulty stormwater infrastructure. Through a community⁻university partnership and using Geographic Information Systems and digital mapping tools, watershed researchers and university students designed a mobile application (app) that enabled them to collect data associated with these stressors to create a spatial narrative, informed by local community knowledge, that offers visual documentation and representation of community conditions that negatively influence the environment, health, and quality of life in urban areas. By elevating the local knowledge and lived experience of community residents and codeveloping a relevant data collection tool, community residents generated fine-grained, street-level, actionable data. This process helped to fill gaps in publicly available datasets about environmental hazards in their watershed and helped residents initiate solution-oriented dialogue with government officials to address problem areas. We demonstrate that community-based knowledge can contribute to and extend scientific inquiry, as well as help communities to advance environmental justice and leverage opportunities for remediation and policy change.

2008-05-30

New modification of the open field was designed to improve automation of the test. The main innovations were: (1) transmitted lighting and (2) estimation of probability to find pixels associated with an animal in the selected region of arena as an objective index of spatial preference. Transmitted (inverted) lighting significantly ameliorated the contrast between an animal and arena and allowed to track white animals with similar efficacy as colored ones. Probability as a measure of preference of selected region was mathematically proved and experimentally verified. A good correlation between probability and classic indices of spatial preference (number of region entries and time spent therein) was shown. The algorithm of calculation of probability to find pixels associated with an animal in the selected region was implemented in the EthoStudio software. Significant interstrain differences in locomotion and the central zone preference (index of anxiety) were shown using the inverted lighting and the EthoStudio software in mice of six inbred strains. The effects of arena shape (circle or square) and a novel object presence in the center of arena on the open field behavior in mice were studied.

The present study was undertaken to understand the zoonotic importance of canine scabies and dermatophytosis with special reference to the knowledge level of dog owners in urban areas of Gujarat. The study was carried out in randomly selected 120 dog owners of 3 urban cities (viz., Ahmedabad, Anand and Vadodara) of Gujarat state, India. Dog owners (i.e., respondents) were subjected to a detailed interview regarding the zoonotic importance of canine scabies and dermatophytosis in dogs. Ex-post-facto research design was selected because of the independent variables of the selected respondent population for the study. The crucial method used in collecting data was a field survey to generate null hypothesis (Ho1). Available data was subjected to statistical analysis. The three independent variables, viz., extension contact (r=0.522**), mass-media exposure (r=0.205*) and management orientation (r=0.264**) had significant relationship with knowledge of dog owners about zoonotic diseases. Other independent variables, viz., education, experience in dog keeping and housing space were observed to have negative and non-significant relationship with knowledge of dog owners about zoonotic diseases. Extension contact, exposure to extension mass-media, management orientation and innovation proneness among dog owners of 3 urban cities of Gujarat state had significant relationship with knowledge of dog owners on zoonotic aspects of canine scabies and dermatophytosis. Data provided new insights on the present status of zoonotic disease-awareness, which would be an aid to plan preventive measures.

2014-01-01

Background: With the influx of rural migrants into urban areas, the spread of HIV has increased significantly in Shaanxi Province (China). Migrant workers are at high risk of HIV infection due to social conditions and hardships (isolation, separation, marginalization, barriers to services, etc.). Objective: We explored the efficacy of a HIV/AIDS prevention and control program for rural migrants in Shaanxi Province, administered at both rural and urban sites. Methods: Guidance concerning HIV/AIDS prevention was given to the experimental group (266 migrants) for 1 year by the center of disease control, community health agencies and family planning department. The intervention was conducted according to the HIV/AIDS Prevention Management Manual for Rural Migrants. A control group of migrants only received general population intervention. The impact of the intervention was evaluated by administering HIV/AIDS knowledge, attitudes and sexual behavior (KAB) questionnaires after 6 and 12 months. Results: In the experimental group; 6 months of intervention achieved improvements in HIV/AIDS related knowledge. After 12 months; HIV/AIDS-related knowledge reached near maximal scores. Attitude and most behaviors scores were significantly improved. Moreover; the experimental group showed significant differences in HIV-AIDS knowledge; attitude and most behavior compared with the control group. Conclusions: The systematic long-term cross-site HIV/AIDS prevention in both rural and urban areas is a highly effective method to improve HIV/AIDS KAB among rural migrants. PMID:24762671

More than 80% of deliveries amongst the urban poor are conducted at home, mostly by traditional birth attendants (TBAs). In all, 29 eligible TBAs in the study area were identified and interviewed to assess their knowledge and practices regarding antenatal and perinatal care. Their knowledge about complications in antenatal and perinatal period was inadequate. The majority provided inadequate advice to the mothers. Over seventy-nine percent (79.3%) gave injections of oxytocin. Sixteen (55.2%) did not wait or waited for less than 10 minutes for the mother to expel the placenta. Fourteen (48.3%) encountered excessive vaginal bleeding, but none knew how to manage it. Overall knowledge and care provided by the TBAs was poor.

RH knowledge and service utilization among unmarried rural-to-urban migrants in three major cities, China

PubMed Central

2011-01-01

Background Large numbers of unmarried migrants are on the continuous move from rural-to-urban areas within China mainland, meanwhile their Reproductive Health (RH) is underserved when it is compared with the present urban RH policies. The purpose of this study is to investigate the RH knowledge and the utilization of RH services among unmarried migrants. Methods A cross-section survey was performed in three cities in China-Shenzhen, Guangzhou and Wuhan. A total of 3,450 rural-to-urban unmarried migrants were chosen according to a purposive sampling method. Around 3,412 (male: 1,680, female: 1,732) were qualified for this study. A face-to-face structured questionnaire survey was used, which focused on the knowledge concerning "fertility, contraception and STD/AIDS," as well as RH service utilization. Results Among unmarried migrants the RH knowledge about pregnancy-fertilization (29.4%) and contraception (9.1%) was at its lowest level. Around 21% of unmarried migrants had pre-marital sexual experience and almost half (47.4%) never used condoms during sexual intercourse. The most obtained RH services was about STD/AIDS health education (female: 49.6%, male: 50.2%) and free prophylactic use of contraceptives and/or condoms (female: 42.5%, male: 48.3%). As for accessing RH checkup services it was at its lowest level among females (16.1%). Those who migrated to Shenzhen (OR = 0.64) and Guangzhou (OR = 0.53) obtained few RH consultations compared to those in Wuhan. The white collar workers received more RH consultations and checkup services than the blue collar workers (all group P < 0.01). Conclusion RH knowledge and the utilization of RH services amongst unmarried migrants remain insufficient in the three studied major cities. This study reveals the important gaps in the RH services' delivery, and highlights the requirements for tailored interventions, including further research, to address more effectively the demands and the needs of the unmarried migrant populations.

Despite the importance of urban trees, their growth reaction to climate change and to the urban heat island effect has not yet been investigated with an international scope. While we are well informed about forest growth under recent conditions, it is unclear if this knowledge can be simply transferred to urban environments. Based on tree ring analyses in ten metropolises worldwide, we show that, in general, urban trees have undergone accelerated growth since the 1960s. In addition, urban trees tend to grow more quickly than their counterparts in the rural surroundings. However, our analysis shows that climate change seems to enhance the growth of rural trees more than that of urban trees. The benefits of growing in an urban environment seem to outweigh known negative effects, however, accelerated growth may also mean more rapid ageing and shortened lifetime. Thus, city planners should adapt to the changed dynamics in order to secure the ecosystem services provided by urban trees.

The field of urban stream ecology has evolved rapidly in the last 3 decades, and it now includes natural scientists from numerous disciplines working with social scientists, landscape planners and designers, and land and water managers to address complex, socioecological problems that have manifested in urban landscapes. Over the last decade, stream ecologists have met 3 times at the Symposium on Urbanization and Stream Ecology (SUSE) to discuss current research, identify knowledge gaps, and promote future research collaborations. The papers in this special series on urbanization and stream ecology include both primary research studies and conceptual synthesis papers spurred from discussions at SUSE in May 2014. The themes of the meeting are reflected in the papers in this series emphasizing global differences in mechanisms and responses of stream ecosystems to urbanization and management solutions in diverse urban streams. Our hope is that this series will encourage continued interdisciplinary and collaborative research to increase the global understanding of urban stream ecology toward stream protection and restoration in urban landscapes.

Public knowledge and beliefs about depression among urban and rural Malays in Malaysia.

PubMed

Swami, Viren; Loo, Phik-Wern; Furnham, Adrian

2010-09-01

This study examined knowledge and beliefs about depression among Malaysian Malays varying in socioeconomic status. A total of 153 urban and 189 rural participants completed a questionnaire in which they had to identify two cases of depression and rate a series of items about the causes and best treatments for depression. Results showed that urban participants were more likely to use psychiatric labels ('depression') for the two vignettes, whereas rural participants tended to use more generic terms ('emotional stress'). Principal components analysis (PCA) showed that beliefs about the causes of depression factored into five components, of which stressful life events was most strongly endorsed by both groups. PCA of treatment items revealed four stable components, of which religious factors were most strongly endorsed. There were also a number of significant between-group differences in the endorsement of these factors (eta(p) (2) = .03-.11), with rural participants generally rating supernatural and religious factors more strongly than urban Malays. These results are discussed in relation to mental health literacy programmes in Malaysia.

The new urban politics as a politics of carbon control.

PubMed

Jonas, Andrew E G; Gibbs, David; While, Aidan

2011-01-01

The new urban politics (NUP) literature has helped to draw attention to a new generation of entrepreneurial urban regimes involved in the competition to attract investment to cities. Interurban competition often had negative environmental consequences for the urban living place. Yet knowledge of the environment was not very central to understanding the NUP. Entrepreneurial urban regimes today are struggling to deal with climate change and reductions in greenhouse gas emissions. Carbon reduction strategies could have profound implications for interurban competition and the politics of urban development. This paper explores the rise of a distinctive low-carbon urban polity—carbon control—and examines its potential ramifications for a new environmental politics of urban development (NEPUD). The NEPUD signals the growing centrality of carbon control in discourses, strategies and struggles around urban development. Using examples from cities in the US and Europe, the paper examines how these new environmental policy considerations are being mainstreamed in urban development politics. Alongside competitiveness, the management of carbon emissions represents a new yet at the same time contestable mode of calculation in urban governance.

2016-11-01

Heart disease is the leading killer of women and remains poorly recognized in high-risk groups. We assessed baseline knowledge gaps and efficacy of a survey-based educational intervention. Four hundred seventy-two women in clinical settings completed pre-/post-surveys for knowledge of: heart disease as the leading killer, risk factors (general and personal levels), heart attack/stroke symptoms, and taking appropriate emergency action. They received a clinic-based educational intervention delivered by healthcare professionals in the course of their clinical care. Change score analyses tested pre-/post-differences in knowledge after the educational intervention, comparing proportions by race, ethnicity, and urban/nonurban status. Knowledge and awareness was low in all groups, especially for American Indian women (p < 0.05). Awareness was overall highest for heart disease as the leading killer, but it was the lowest for taking appropriate action (13% of Hispanic, 13% of American Indian, 29% of African American, and 18% of nonurban women; p < 0.05). For all women, knowledge of the major risk factors was low (58%) as was knowledge of their personal levels for risk factors (73% awareness for hypertension, 54% for cholesterol, and 50% for diabetes). The intervention was effective (% knowledge gain) in all groups of women, particularly for raising awareness of: (1) heart disease as the leading killer in American Indian (25%), Hispanic (18%), and nonurban (15%) women; (2) taking appropriate action for American Indian (80%), African American (64%), non-Hispanic (55%), and urban (56%) women; (3) heart disease risk factors for Hispanic (56%) and American Indian (47%) women; and (4) heart disease and stroke symptoms in American Indian women (54% and 25%, respectively). Significant knowledge gaps persist for heart disease in high-risk women, suggesting that these gaps and groups should be targeted by educational programs. We specify areas of need, and we demonstrate efficacy of a clinic-based educational intervention that can be of utility to busy healthcare professionals.

Public knowledge and beliefs about depression among urban and rural Chinese in Malaysia.

PubMed

Loo, Phik-Wern; Furnham, Adrian

2012-09-01

The study compared knowledge and beliefs about depression among urban and rural Chinese in a Malaysian sample. A total of 409 participants were asked to identify cases of depression varying in intensity from two vignettes and rate their beliefs regarding a list of possible causes and treatments for depression. The urban Chinese were more likely to identify depression as the problem in the vignette. Beliefs about causes of depression were factored into five components, whereas beliefs about treatment for depression factored into four components. The results indicated that the causes most strongly endorsed were stress and pressure, and standard treatments rated the highest as treatments for depression. Overall, depression literacy was moderate for Chinese Malaysians. The results are discussed in relation to Chinese cultural beliefs about depression. Limitations of this preliminary study were acknowledged. Copyright © 2012 Elsevier B.V. All rights reserved.

To access knowledge and practices related to the oral health of geriatrics among the health care providers practicing in urban and rural areas. Older adults have identified a number of barriers that contribute to lack of dental service use. However, barriers that clinicians encounter in providing dental treatment to older adults are not as clear-cut. 236 health professionals (of allopathy, ayurveda, and homeopathy) from urban and rural areas were assessed by means of structured questionnaire related to oral health practices and beliefs. Doctors practicing in urban areas assessed dental care needs more frequently (P = 0.038) and performed greater practices related to oral health of geriatrics (P = 0.043) than the doctors practicing in primary health care (PHC) centers (rural) (P = 0.038). Owing to the relative lack of knowledge among rural practitioners, there is a need to integrate primary health care with oral care in rural areas.

This paper presents the results of a research in urban ethnobotany, conducted in a market of Bolivian immigrants in the neighborhood of Liniers, Ciudad Autónoma de Buenos Aires (Argentina). Functional foods and nutraceuticals belonging to 50 species of 18 families, its products, and uses were recorded. Some products are exclusive from the Bolivian community; others are frequent within the community, but they are also available in the general commercial circuit; they are introduced into it, generally, through shops called dietéticas (“health-food stores”), where products associated with the maintenance of health are sold. On this basis, the traditional and nontraditional components of the urban botanical knowledge were evaluated as well as its dynamics in relation to the diffusion of the products. Both the framework and methodological design are innovative for the studies of the urban botanical knowledge and the traditional markets in metropolitan areas. PMID:22203866

Observing the Vertical Dimensions of Singapore's Urban Heat Island

Chow, W. T. L.; Ho, D. X. Q.

2015-12-01

In numerous cities, measurements of urban warmth in most urban heat island (UHI) studies are generally constrained towards surface or near-surface (<2 m above ground) levels across horizontal variations in land use and land cover. However, there has been hitherto limited attention towards the measurement of vertical temperature profiles extending from the urban surface through to the urban boundary layer. Knowledge of these profiles, through how they vary over different local urban morphologies, and develop with respect to synoptic meteorological conditions, are important towards several aspects of UHI research; these include validating modelling urban canopy lapse rate profiles or estimating the growth of urban plumes. In this study, we utilised temperature sensors attached onto remote controlled aerial quadcopter platforms to measure urban temperature and humidity profiles in Singapore, which is a rapidly urbanizing major tropical metropolis. These profiles were measured from the surface to ~100 m above ground level, a height which includes all of the urban canopy and parts of the urban boundary layer. Initial results indicate significant variations in stability measured over different land uses (e.g. urban park, high-rise residential, commercial); these profiles are also temporally dynamic, depending on the time of day and larger-scale weather conditions.

Building customer capital through knowledge management processes in the health care context.

PubMed

Liu, Sandra S; Lin, Carol Yuh-Yun

2007-01-01

Customer capital is a value generated and an asset developed from customer relationships. Successfully managing these relationships is enhanced by knowledge management (KM) infrastructure that captures and transfers customer-related knowledge. The execution of such a system relies on the vision and determination of the top management team (TMT). The health care industry in today's knowledge economy encounters similar challenges of consumerism as its business sector. Developing customer capital is critical for hospitals to remain competitive in the market. This study aims to provide taxonomy for cultivating market-based organizational learning that leads to building of customer capital and attaining desirable financial performance in health care. With the advancement of technology, the KM system plays an important moderating role in the entire process. The customer capital issue has not been fully explored either in the business or the health care industry. The exploratory nature of such a pursuit calls for a qualitative approach. This study examines the proposed taxonomy with the case hospital. The lessons learned also are reflected with three US-based health networks. The TMT incorporated the knowledge process of conceptualization and transformation in their organizational mission. The market-oriented learning approach promoted by TMT helps with the accumulation and sharing of knowledge that prepares the hospital for the dynamics in the marketplace. Their key knowledge advancement relies on both the professional arena and the feedback of customers. The institutionalization of the KM system and organizational culture expands the hospital's customer capital. The implication is twofold: (1) the TMT is imperative for the success of building customer capital through KM process; and (2) the team effort should be enhanced with a learning culture and sharing spirit, in particular, active nurse participation in decision making and frontline staff's role in providing a delightfully surprising patient experience.

Social Networks and Health: Understanding the Nuances of Healthcare Access between Urban and Rural Populations.

Amoah, Padmore Adusei; Edusei, Joseph; Amuzu, David

2018-05-13

Communities and individuals in many sub-Saharan African countries often face limited access to healthcare. Hence, many rely on social networks to enhance their chances for adequate health care. While this knowledge is well-established, little is known about the nuances of how different population groups activate these networks to improve access to healthcare. This paper examines how rural and urban dwellers in the Ashanti Region in Ghana distinctively and systematically activate their social networks to enhance access to healthcare. It uses a qualitative cross-sectional design, with in-depth interviews of 79 primary participants (28 urban and 51 rural residents) in addition to the views of eight community leaders and eight health personnel. It was discovered that both intimate and distanced social networks for healthcare are activated at different periods by rural and urban residents. Four main stages of social networks activation, comprising different individuals and groups were observed among rural and urban dwellers. Among both groups, physical proximity, privacy, trust and sense of fairness, socio-cultural meaning attached to health problems, and perceived knowledge and other resources (mainly money) held in specific networks inherently influenced social network activation. The paper posits that a critical analysis of social networks may help to tailor policy contents to individuals and groups with limited access to healthcare.

Environmental Factors and Zoonotic Pathogen Ecology in Urban Exploiter Species.

Rothenburger, Jamie L; Himsworth, Chelsea H; Nemeth, Nicole M; Pearl, David L; Jardine, Claire M

2017-09-01

Knowledge of pathogen ecology, including the impacts of environmental factors on pathogen and host dynamics, is essential for determining the risk that zoonotic pathogens pose to people. This review synthesizes the scientific literature on environmental factors that influence the ecology and epidemiology of zoonotic microparasites (bacteria, viruses and protozoa) in globally invasive urban exploiter wildlife species (i.e., rock doves [Columba livia domestica], European starlings [Sturnus vulgaris], house sparrows [Passer domesticus], Norway rats [Rattus norvegicus], black rats [R. rattus] and house mice [Mus musculus]). Pathogen ecology, including prevalence and pathogen characteristics, is influenced by geographical location, habitat, season and weather. The prevalence of zoonotic pathogens in mice and rats varies markedly over short geographical distances, but tends to be highest in ports, disadvantaged (e.g., low income) and residential areas. Future research should use epidemiological approaches, including random sampling and robust statistical analyses, to evaluate a range of biotic and abiotic environmental factors at spatial scales suitable for host home range sizes. Moving beyond descriptive studies to uncover the causal factors contributing to uneven pathogen distribution among wildlife hosts in urban environments may lead to targeted surveillance and intervention strategies. Application of this knowledge to urban maintenance and planning may reduce the potential impacts of urban wildlife-associated zoonotic diseases on people.

A comparative study of perception of sickle cell anaemia by married Nigeria rural and urban women.

Adeodu, O O; Alimi, T; Adekile, A D

2000-01-01

Environmental factors may influence perception of or attitude to chronic disorders. The perception of sickle cell anaemia (SCA by 165 married Nigerian rural and 507 urban women was studied to determine how living in an urban or rural environment may influence perception. None of the subjects had children with SCA. The instrument used for data collection was a structured questionnaire designed to enquire into their knowledge about the cause, precipitating factors for crises, clinical features of SCA and their opinions regarding traditional and modern treatment options for the disorder. As a group, urban women had better knowledge about SCA than rural women probably because their social environment afforded a wider scope for interaction with and information exchange among people. For most respondents, the educational institutions attended the health institutions in the locality and the electronic media were poor sources of information on SCA. The study showed a serious lack of information about important aspects of SCA among rural women. We think the training of primary health care providers as counsellors on SCA, the inclusion of instruction about SCA in the curriculum of schools and sustained outreach programmes on SCA on the electronic media would ensure early education of people in both rural and urban communities and help to improve perception of the disorder.

Infant and young child feeding has been recognised as an essential element to improve growth of children, especially in developing countries where malnutrition among children and its dire consequences are very prevalent. However, little attention has been paid on the influence of fathers on child feeding practices, although fathers are very important in raising well-adjusted, happy and successful children. Therefore, this study aimed to assess the influence of fathers' child feeding knowledge and practice on children's dietary diversity. A community-based comparative cross-sectional study was conducted among 850 eligible urban and rural households with children of 6-23 months. The father and mother of the child were interviewed on children's dietary diversity and fathers' knowledge and practice of child feeding. Nearly half (46%) of the children in the rural district did not meet the minimum dietary diversity, and in the urban district, the rate was even worse (72%). Grains were the common food group given to the children in both districts, whereas flesh food was the least commonly consumed food group. Additionally, low vitamin A-rich food and other fruit and vegetable consumption seem to be a problem in both districts. Almost all dimensions of fathers' knowledge and practice were significantly related to children's minimum dietary diversity; especially, fathers' knowledge of food groups was an important predictor (P-value < 0.001) in both districts. Interventions that focus on the fathers' knowledge of child feeding, especially about food groups, are recommended to improve children's dietary diversity in the study communities. © 2014 John Wiley & Sons Ltd.

Breast feeding promotion in an urban and a rural Jamaican hospital.

Cunningham, W E; Segree, W

1990-01-01

Breast feeding promotion has been a national priority in Jamaica since the mid-1970s. Despite this effort, breast feeding rates have continued to decline there, especially in urban areas. Studies of the role of health professionals in promoting breast feeding have shown that specific practices encourage breast feeding, while others discourage it. In the context of declining breast feeding in a nation committed to promoting it, the goal of this study was to explore the relationship between specific health professional practices, mothers' breast feeding, and mothers' knowledge of breast feeding in rural and urban Jamaica. To accomplish this goal, a structured interview was administered to 113 mothers of infants age 0-6 months at one urban (n = 62) and one rural (n = 51) hospital, regarding (1) physician and nurse practices known to affect breast feeding, (2) mothers' own breast feeding practices, and (3) mothers knowledge of breast feeding issues. Physician and nurse visits were also directly observed to confirm responses given to the questionnaire and to assess the resources devoted to teaching mothers about breast feeding. While extensive lectures, posters and pamphlets promoting breast feeding were provided for mothers at the urban hospital, far fewer educational resources were available for mothers at the rural hospital. Overall, however, health professional practices discouraging breast feeding were observed more frequently at the urban hospital than at the rural hospital, whereas practices promoting breast feeding were more common at the rural hospital. At the rural hospital, mothers' breast feeding practices more closely approximated recommendations than at the urban hospital.(ABSTRACT TRUNCATED AT 250 WORDS)

Differential effects of exposure to low-light or high-light open-field on anxiety-related behaviors; relationship to c-Fos expression in serotonergic and non-serotonergic neurons in the dorsal raphe nucleus

2007-01-01

Serotonergic systems arising from the mid-rostrocaudal and caudal dorsal raphe nucleus (DR) have been implicated in the facilitation of anxiety-related behavioral responses by anxiogenic drugs or aversive stimuli. In this study we attempted to determine a threshold to engage serotonergic neurons in the DR following exposure to aversive conditions in an anxiety-related behavioral test. We manipulated the intensity of anxiogenic stimuli in studies of male Wistar rats by leaving them undisturbed (CO), briefly handling them (HA), or exposing them to an open-field arena for 15-min under low-light (LL: 8-13 lux) or high-light (HL: 400-500 lux) conditions. Rats exposed to HL conditions responded with reduced locomotor activity, reduced time spent exploring the center of the arena, a lower frequency of rearing and grooming, and an increased frequency of facing the corner of the arena compared to LL rats. Rats exposed to HL conditions had small but significant increases in c-Fos expression within serotonergic neurons in subdivisions of the rostral DR. Exposure to HL conditions did not alter c-Fos responses in serotonergic neurons in any other DR subdivision. In contrast, rats exposed to the open-field arena had increased c-Fos expression in non-serotonergic cells throughout the DR compared to CO rats, and this effect was particularly apparent in the dorsolateral part of the DR. We conclude that exposure to HL conditions, compared to LL conditions, increased anxiety-related behavioral responses in an open-field arena but this stimulus was at or below the threshold required to increase c-Fos expression in serotonergic neurons.

Path planning on cellular nonlinear network using active wave computing technique

NASA Astrophysics Data System (ADS)

Yeniçeri, Ramazan; Yalçın, Müstak E.

2009-05-01

This paper introduces a simple algorithm to solve robot path finding problem using active wave computing techniques. A two-dimensional Cellular Neural/Nonlinear Network (CNN), consist of relaxation oscillators, has been used to generate active waves and to process the visual information. The network, which has been implemented on a Field Programmable Gate Array (FPGA) chip, has the feature of being programmed, controlled and observed by a host computer. The arena of the robot is modelled as the medium of the active waves on the network. Active waves are employed to cover the whole medium with their own dynamics, by starting from an initial point. The proposed algorithm is achieved by observing the motion of the wave-front of the active waves. Host program first loads the arena model onto the active wave generator network and command to start the generation. Then periodically pulls the network image from the generator hardware to analyze evolution of the active waves. When the algorithm is completed, vectorial data image is generated. The path from any of the pixel on this image to the active wave generating pixel is drawn by the vectors on this image. The robot arena may be a complicated labyrinth or may have a simple geometry. But, the arena surface always must be flat. Our Autowave Generator CNN implementation which is settled on the Xilinx University Program Virtex-II Pro Development System is operated by a MATLAB program running on the host computer. As the active wave generator hardware has 16, 384 neurons, an arena with 128 × 128 pixels can be modeled and solved by the algorithm. The system also has a monitor and network image is depicted on the monitor simultaneously.

Increasing availability of antiretroviral treatment (ART) has led HIV to be considered a chronic disease, shifting attention to focus on quality of life including mental wellbeing. We investigated knowledge and causal attributions for mental disorders in HIV-positive children and adolescents in rural and urban Uganda. This qualitative study was nested in an epidemiological mental health study among HIV-positive children and adolescents aged 5-17 years in rural and urban Uganda. In-depth interviews were conducted with caregivers of HIV-positive children (5-11 years) and adolescents (12-17 years) in HIV care. Interviews were audio recorded with permission from participants and written consent and assent sought before study procedures. Thirty eight participants (19 caregivers, 19 children/adolescents) were interviewed. Age range of caregivers was 28-69 years; majority were female (17). Caregivers had little knowledge on mental disorders ;only 3 related the vignette to a mental problem  and attributed it to: improper upbringing, violence, poverty and bereavement. Five adolescents identified vignettes as portraying mental disorders caused by: ill-health of parents, bereavement, child abuse, discrimination, HIV and poverty. Caregivers are not knowledgeable about behavioural and emotional challenges in HIV-positive children/adolescents. Mental health literacy programmes at HIV care clinics are essential to enhance treatment-seeking for mental health.

Gravel and (or) crushed-rock aggregates are essential commodities for urban development, but supplies in many places are exhausted or otherwise eliminated by urban growth. Gravel resources may be exhausted by exploitation, covered by urban spread, or eliminated from production by zoning. this conflict between a growing need and a progressively reduced supply can be forestalled by informed land-use planning. Fundamental to intelligent decisions on land use is knowledge of the physical character, distribution, and quantity of the gravel resources of an area, and of the alternative resource of rock suitable for crushing. This map has been prepared to supply data basic to land-use planning in the Front Range Urban Corridor.

A roadmap to effective urban climate change adaptation

Setiadi, R.

2018-03-01

This paper outlines a roadmap to effective urban climate change adaptation built from our practical understanding of the evidence and effects of climate change and the preparation of climate change adaptation strategies and plans. This roadmap aims to drive research in achieving fruitful knowledge and solution-based achievable recommendations in adapting to climate change in urban areas with effective and systematic manner. This paper underscores the importance of the interplay between local government initiatives and a national government for effective adaptation to climate change and takes into account the policy process and politics. This paper argues that effective urban climate change adaptation has a contribution to build urban resilience and helps the achievement of national government goals and targets in climate change adaptation.

2000-03-01

The repellency of N,N-diethyl-3-methylbenzamide (deet) to Triatoma infestans (Klug) (Hemiptera: Reduviidae) was evaluated using third-instar nymphs and a video tracking technique. Three experimental designs were used: (a) the test arena floor was divided into two halves, only one of which was treated with deet; (b) the arena floor was divided into an inner circle and an outer ring, only the latter treated with deet; (c) half of the test arena was covered by a filter paper roof treated with deet (out of reach of the nymphs). In all three types of experiment, a repellent effect was demonstrated proportional to the dose of deet. When a host (pigeon) was shielded by deet-treated gauze, the rate of blood-feeding by the nymphs was inhibited. Topical pre-treatment of the nymphs with N-ethylmaleimide, to block chemoreception, inhibited the repellency.

Constrained recycling: a framework to reduce landfilling in developing countries.

PubMed

Diaz, Ricardo; Otoma, Suehiro

2013-01-01

This article presents a model that integrates three branches of research: (i) economics of solid waste that assesses consumer's willingness to recycle and to pay for disposal; (ii) economics of solid waste that compares private and social costs of final disposal and recycling; and (iii) theories on personal attitudes and social influence. The model identifies two arenas where decisions are made: upstream arena, where residents are decision-makers, and downstream arena, where municipal authorities are decision-makers, and graphically proposes interactions between disposal and recycling, as well as the concept of 'constrained recycling' (an alternative to optimal recycling) to guide policy design. It finally concludes that formative instruments, such as environmental education and benchmarks, should be combined with economic instruments, such as subsidies, to move constraints on source separation and recycling in the context of developing countries.

Nontraditional Settlement Patterns and Typhoon Hazard on Contemporary Majuro Atoll, Republic of the Marshall Islands

Low-lying islands and atolls are particularly prone to storm surges created by tropical depressions and typhoons. This paper presents a case study of traditional and contemporary settlement patterns of Majuro, the capital of the Republic of the Marshall Islands, and discusses its vulnerability to such storm surges. The paper shows that the application of traditional knowledge extends to the realm of urban planning and that, in fact, ignoring this traditional knowledge as expressed in pre-World War II settlement patterns, exposes urban development to increased flood hazards, a risk which may exact a price too high in life and property.

Main Road Extraction from ZY-3 Grayscale Imagery Based on Directional Mathematical Morphology and VGI Prior Knowledge in Urban Areas

2015-01-01

Main road features extracted from remotely sensed imagery play an important role in many civilian and military applications, such as updating Geographic Information System (GIS) databases, urban structure analysis, spatial data matching and road navigation. Current methods for road feature extraction from high-resolution imagery are typically based on threshold value segmentation. It is difficult however, to completely separate road features from the background. We present a new method for extracting main roads from high-resolution grayscale imagery based on directional mathematical morphology and prior knowledge obtained from the Volunteered Geographic Information found in the OpenStreetMap. The two salient steps in this strategy are: (1) using directional mathematical morphology to enhance the contrast between roads and non-roads; (2) using OpenStreetMap roads as prior knowledge to segment the remotely sensed imagery. Experiments were conducted on two ZiYuan-3 images and one QuickBird high-resolution grayscale image to compare our proposed method to other commonly used techniques for road feature extraction. The results demonstrated the validity and better performance of the proposed method for urban main road feature extraction. PMID:26397832

Perceptions of northeast Thai breastfeeding mothers regarding facilitators and barriers to six-month exclusive breastfeeding: focus group discussions.

2018-01-01

The 6-month exclusive breastfeeding rate in the Northeast region of Thailand has recently significantly decreased in contrast to all other regions in Thailand. The factors that have influenced this decrease remain unknown. Hence, it is suggested that an investigation into factors that could improve or hinder EBF for 6 months in Northeast Thailand may be required to inform the development of relevant interventions to improve this situation. This study aimed to identify perceived facilitators and barriers to providing exclusive breastfeeding for 6 months in Northeast Thailand among breastfeeding mothers. Six focus group discussions were conducted with a total of 30 mothers aged 20 to 40 years who had children aged between 4 and 6 months and were currently breastfeeding or had breastfeeding experience. Participants were recruited through self-selection sampling from Khonkaen hospital (urban), Numphong hospital (peri-urban) and private hospitals (urban) in Khonkaen, Thailand. Thematic analysis was employed to analyse the data. Five main themes, with 10 sub-themes, were identified as either facilitators (+) or barriers (-), or in some cases, as both (+/-). Breastfeeding knowledge, perceptions, maternal circumstances, support, and traditional food were the main identified themes. Mother's breastfeeding knowledge, intention to breastfeed, and social media were perceived as facilitators. Perceptions, employment, and formula milk promotion were perceived as barriers. Family, healthcare, and traditional food were perceived as both facilitators and barriers. The perception that social media was a way to access breastfeeding knowledge and support mothers in Northeast Thailand emerged as a new facilitating factor that had not previously been identified in Thai literature relating to facilitators and barriers to exclusive breastfeeding. Intention to breastfeed, family support, healthcare support and traditional food were mentioned by all groups, whereas mothers from urban areas specifically mentioned mother's breastfeeding knowledge, social media and employment sub-themes. Only mothers from the peri-urban area mentioned formula milk promotion and only mothers who had delivered in public hospitals mentioned the perceptions sub-theme. Knowledge about these facilitators and barriers may inform the design and development of specific and relevant interventions to improve the 6-month exclusive breastfeeding rate in the Northeast region of Thailand and be useful in other contexts. Social media emerged as a newly perceived facilitator in the Thai context and may be a useful inclusion in a 6-month exclusive breastfeeding intervention model.

Nowcasting and forecasting of the magnetopause and bow shock—A status update

Petrinec, S. M.; Redmon, R. J.; Rastaetter, L.

2017-01-01

There has long been interest in knowing the shape and location of the Earth's magnetopause and of the standing fast-mode bow shock upstream of the Earth's magnetosphere. This quest for knowledge spans both the research and operations arenas. Pertinent to the latter, nowcasting and near-term forecasting are important for determining the extent to which the magnetosphere is compressed or expanded due to the influence of the solar wind bulk plasma and fields and the coupling to other magnetosphere-ionosphere processes with possible effects on assets. This article provides an update to a previous article on the same topic published 15 years earlier, with focus on studies that have been conducted, the current status of nowcasting and forecasting of geophysical boundaries, and future endeavors.

The Eighth Annual NASA/Contractors Conference and 1991 National Symposium on Quality and Productivity provided a forum to exchange knowledge and experiences in these areas of continuous improvement. The more than 1,100 attendees from government, industry, academia, community groups, and the international arena had a chance to learn about methods, tools, and strategies for excellence and to discuss continuous improvement strategies, successes, and failures. This event, linked via satellite to concurrent conferences hosted by the NASA Goddard Space Flight Center in Greenbelt, Maryland, and Martin Marietta Astronautics Group in Denver, Colorado, also explored extending the boundaries of Total Quality Management to include partnerships for quality within communities and encouraged examination, evaluation, and change to incorporate the principles of continuous improvement.

Women's little secrets: defining the boundaries of reproductive knowledge in sixteenth-century France. Society for the social history of medicine student essay competition winner, 1999.

Broomhall, Susan

2002-04-01

Although there has been much recent work on the contribution of midwives to early modern medical practice, there has been less investigation of the participation of other women outside of the corporative or professional medical arena. This article seeks to examine how élite women were involved in medical discussion of reproduction, using the sixteenth-century correspondence surrounding the reproductive health of Elisabeth de Valois, Queen of Spain. Letters passed between the courts of France and Spain demonstrate that control of Elisabeth's reproductive health became a source of conflict between the Spanish and French. National rivalries created possibilities for women to be authoritative contributors in medical discussion with the support of university-trained physicians.

Collaborations between home healthcare agencies and schools of nursing: bridging the theory-practice gap at home.

Mager, Diana R; Bradley, Sharon

2013-10-01

Home healthcare (HHC) agencies and schools of nursing (SONs) share the mutual goal of using evidence-based knowledge to deliver care while fostering a professionally stimulating environment. As HHC agencies strive to deliver clinically effective, cost-efficient, patient-centered nursing care, SONs use scholarly methods to develop sound practitioners with investigative skills. Collaborations have long existed between these two entities, but few studies describe how theory and practice meld in the ever-growing HHC arena. The purpose of this article is to highlight the need for such future collaborations and to summarize some of the successful collaborative methods used by schools and agencies. Additionally, the collaboration between one nonprofit HHC agency and a university-based SON is described along with the challenges and benefits to both partners.

Planetary protection policy (U.S.A.)

Rummel, John D.

1992-01-01

Through existing treaty obligations of the United States, NASA is committed to exploring space while avoiding biological contamination of the planets, and to the protection of the earth against harm from materials returned from space. Because of the similarities between Mars and earth, plans for the exploration of Mars evoke discussions of these Planetary Protection issues. U.S. Planetary Protection Policy will be focused on the preservation of these goals in an arena that will change with the growth of scientific knowledge about the Martian environment. Early opportunities to gain the appropriate data will be used to guide later policy implementation. Because human presence on Mars will result in the end of earth's separation from the Martian environment, it is expected that precursor robotic missions will address critical planetary protection concerns before humans arrive.

Deconstructing the evidence-based discourse in health sciences: truth, power and fascism.

PubMed

Holmes, Dave; Murray, Stuart J; Perron, Amélie; Rail, Geneviève

2006-09-01

Background  Drawing on the work of the late French philosophers Deleuze and Guattari, the objective of this paper is to demonstrate that the evidence-based movement in the health sciences is outrageously exclusionary and dangerously normative with regards to scientific knowledge. As such, we assert that the evidence-based movement in health sciences constitutes a good example of microfascism at play in the contemporary scientific arena. Objective  The philosophical work of Deleuze and Guattari proves to be useful in showing how health sciences are colonised (territorialised) by an all-encompassing scientific research paradigm - that of post-positivism - but also and foremost in showing the process by which a dominant ideology comes to exclude alternative forms of knowledge, therefore acting as a fascist structure. Conclusion  The Cochrane Group, among others, has created a hierarchy that has been endorsed by many academic institutions, and that serves to (re)produce the exclusion of certain forms of research. Because 'regimes of truth' such as the evidence-based movement currently enjoy a privileged status, scholars have not only a scientific duty, but also an ethical obligation to deconstruct these regimes of power.

Failure to stem trends of ecological disruption and associated loss of ecosystem services worldwide is partly due to the inadequate integration of the human dimension into environmental decision-making. Decision-makers need knowledge of the human dimension of resource systems and of the social consequences of decision-making if environmental management is to be effective and adaptive. Social scientists have a central role to play, but little guidance exists to help them influence decision-making processes. We distil 348 years of cumulative experience shared by 31 environmental experts across three continents into advice for social scientists seeking to increase their influence in the environmental policy arena. Results focus on the importance of process, engagement, empathy and acumen and reveal the importance of understanding and actively participating in policy processes through co-producing knowledge and building trust. The insights gained during this research might empower a science-driven cultural change in science-policy relations for the routine integration of the human dimension in environmental decision making; ultimately for an improved outlook for earth’s ecosystems and the billions of people that depend on them.

Opening our eyes to Global Health; a philosophy of universal values.

PubMed

Wass, Val

2015-12-01

Globalization is advancing at a pace. As we strive to introduce 'Global Health' into clinical curricula we risk fundamental misunderstandings unless we clearly define what we aim to achieve. Clinicians must be prepared for a life time of uncertainty, change and challenge. The fluctuating world arena will undoubtedly impact on their future work in ways we cannot predict. Population migration, climate change and shifts in cultural dominance are already at play. Global health risks being translated through the eyes of Western ideology as disease-based curricula focused paternalistically on 'helping' the developing world. We must not lack humility to open eyes to learning within the context of increasingly diverse environments and patient populations. Global health is as 'local' as it is 'international'. It should be viewed, I argue, as a philosophy based on the values and expectations found within ourselves and our communities. Responding to globalization lies not only in knowledge but embraces human rights, justice and, most importantly, self-awareness. Knowledge is more easily translated into curriculum objectives. We risk letting future clinicians and their patients down if we ignore the other universal values.

Radiation Brain Drain? The Impact of Demographic Change on U.S. Radiation Protection.

PubMed

Hricak, Hedvig; Dauer, Lawrence T

2017-02-01

The use of radiation has a substantial beneficial impact, particularly in the areas of medicine, energy production, basic science research, and industrial applications. Radiation protection knowledge and experience are required for acquiring and implementing scientific knowledge to protect workers, members of the public, and the environment from potential harmful effects of ionizing radiation while facilitating the beneficial use and development of radiation-based technologies. However, demographic changes are negatively impacting U.S. radiation protection and response capabilities. The number of radiation professionals continues to decrease even as the demand for such professionals is growing. These concerns are most pronounced in the medical, energy, research, and security arenas. Though the United States has been the world leader in radiation protection and radiation sciences for many years, the country has no strategic plan to ensure the maintenance of expertise in radiobiology, radiation physics, and radiation protection. Solving this problem will require a significant increase in federal and state funding as well as formal partnerships and initiatives among academia, professional societies, government, and the private sector.

A (Mis)Match of User Needs, Science Priorities, and Funder Support: A Case Study of Arctic Sea Ice Knowledge

2016-12-01

Declining Arctic sea ice, and its impacts on the Arctic and globe, is a topic of increasing attention by scientists, diverse stakeholder groups, and the media. Research on Arctic sea ice is broad and inter-disciplinary, ranging from new technologies to monitor sea ice, to process studies, to examining the impacts of declining sea ice on ecosystems and people. There remain barriers, however, in transferring scientific knowledge of sea ice to serve decision-maker needs. This poster will examine possible causes of these barriers—including issues of communications across disciplines and perspectives, professional culture, funding agency restrictions, and the state of the science—through the lens of Arctic sea ice efforts that have occurred over the past several years. The poster will draw on experiences from the Sea Ice for Walrus Outlook (https://www.arcus.org/search-program/siwo), the Sea Ice Outlook (https://www.arcus.org/sipn/sea-ice-outlook), and various science planning exercises. Finally, the poster will synthesize relevant efforts in this arena and highlight opportunities for improvement.

Bioprospecting the African Renaissance: The new value of muthi in South Africa

PubMed Central

Reihling, Hanspeter CW

2008-01-01

This article gives an overview of anthropological research on bioprospecting in general and of available literature related to bioprospecting particularly in South Africa. It points out how new insights on value regimes concerning plant-based medicines may be gained through further research and is meant to contribute to a critical discussion about the ethics of Access and Benefit Sharing (ABS). In South Africa, traditional healers, plant gatherers, petty traders, researchers and private investors are assembled around the issues of standardization and commercialization of knowledge about plants. This coincides with a nation-building project which promotes the revitalization of local knowledge within the so called African Renaissance. A social science analysis of the transformation of so called Traditional Medicine (TM) may shed light onto this renaissance by tracing social arenas in which different regimes of value are brought into conflict. When medicinal plants turn into assets in a national and global economy, they seem to be manipulated and transformed in relation to their capacity to promote health, their market value, and their potential to construct new ethics of development. In this context, the translation of socially and culturally situated local knowledge about muthi into global pharmaceuticals creates new forms of agency as well as new power differentials between the different actors involved.

Behavioral research in pigeons with ARENA: An automated remote environmental navigation apparatus

PubMed Central

Leising, Kenneth J.; Garlick, Dennis; Parenteau, Michael; Blaisdell, Aaron P.

2009-01-01

Three experiments established the effectiveness of an Automated Remote Environmental Navigation Apparatus (ARENA) developed in our lab to study behavioral processes in pigeons. The technology utilizes one or more wireless modules, each capable of presenting colored lights as visual stimuli to signal reward and of detecting subject peck responses. In Experiment 1, subjects were instrumentally shaped to peck at a single ARENA module following an unsuccessful autoshaping procedure. In Experiment 2, pigeons were trained with a simultaneous discrimination procedure during which two modules were illuminated different colors; pecks to one color (S+) were reinforced while pecks to the other color (S−) were not. Pigeons learned to preferentially peck the module displaying the S+. In Experiment 3, two modules were lit the same color concurrently from a set of six colors in a conditional discrimination task. For three of the colors pecks to the module in one location (e.g., upper quadrant) were reinforced while for the remaining colors pecks at the other module (e.g., lower quadrant) were reinforced. After learning this discrimination, the color-reinforced location assignments were reversed. Pigeons successfully acquired the reversal. ARENA is an automated system for open-field studies and a more ecologically valid alternative to the touchscreen. PMID:19429204

Differences between appetitive and aversive reinforcement on reorientation in a spatial working memory task.

PubMed

Golob, Edward J; Taube, Jeffrey S

2002-10-17

Tasks using appetitive reinforcers show that following disorientation rats use the shape of an arena to reorient, and cannot distinguish two geometrically similar corners to obtain a reward, despite the presence of a prominent visual cue that provides information to differentiate the two corners. Other studies show that disorientation impairs performance on certain appetitive, but not aversive, tasks. This study evaluated whether rats would make similar geometric errors in a working memory task that used aversive reinforcement. We hypothesized that in a task that used aversive reinforcement rats that were initially disoriented would not reorient by arena shape and thus make similar geometric errors. Tests were performed in a rectangular arena having one polarizing cue. In the appetitive condition water consumption was the reward. The aversive condition was a water maze task with reinforcement provided by escape to a hidden platform. In the aversive condition rats returned to the reinforced corner significantly more often than in the dry condition, and did not favor the diagonally opposite corner. Results show that rats can use cues besides arena shape to reorient in an aversive reinforcement condition. These findings may also reflect different strategies, with an escape/homing strategy in the wet condition and a foraging strategy in the dry condition.

Nonstructural urban stormwater quality measures: building a knowledge base to improve their use.

PubMed

Taylor, André C; Fletcher, Tim D

2007-05-01

This article summarizes a research project that investigated the use, performance, cost, and evaluation of nonstructural measures to improve urban stormwater quality. A survey of urban stormwater managers from Australia, New Zealand, and the United States revealed a widespread trend of increasing use of nonstructural measures among leading stormwater management agencies, with at least 76% of 41 types of nonstructural measures being found to be increasing in use. Data gathered from the survey, an international literature review, and a multicriteria analysis highlighted four nonstructural measures of greatest potential value: mandatory town planning controls that promote the adoption of low-impact development principles and techniques; development of strategic urban stormwater management plans for a city, shire, or catchment; stormwater management measures and programs for construction/building sites; and stormwater management activities related to municipal maintenance operations such as maintenance of the stormwater drainage network and manual litter collections. Knowledge gained on the use and performance of nonstructural measures from the survey, literature review, and three trial evaluation projects was used to develop tailored monitoring and evaluation guidelines for these types of measure. These guidelines incorporate a new evaluation framework based on seven alternative styles of evaluation that range from simply monitoring whether a nonstructural measure has been fully implemented to monitoring its impact on waterway health. This research helps to build the stormwater management industry's knowledge base concerning nonstructural measures and provides a practical tool to address common impediments associated with monitoring and evaluating the performance and cost of these measures.

Identification of an urban fractured-rock aquifer dynamics using an evolutionary self-organizing modelling

NASA Astrophysics Data System (ADS)

Hong, Yoon-Seok; Rosen, Michael R.

2002-03-01

An urban fractured-rock aquifer system, where disposal of storm water is via 'soak holes' drilled directly into the top of fractured-rock basalt, has a highly dynamic nature where theories or knowledge to generate the model are still incomplete and insufficient. Therefore, formulating an accurate mechanistic model, usually based on first principles (physical and chemical laws, mass balance, and diffusion and transport, etc.), requires time- and money-consuming tasks. Instead of a human developing the mechanistic-based model, this paper presents an approach to automatic model evolution in genetic programming (GP) to model dynamic behaviour of groundwater level fluctuations affected by storm water infiltration. This GP evolves mathematical models automatically that have an understandable structure using function tree representation by methods of natural selection ('survival of the fittest') through genetic operators (reproduction, crossover, and mutation). The simulation results have shown that GP is not only capable of predicting the groundwater level fluctuation due to storm water infiltration but also provides insight into the dynamic behaviour of a partially known urban fractured-rock aquifer system by allowing knowledge extraction of the evolved models. Our results show that GP can work as a cost-effective modelling tool, enabling us to create prototype models quickly and inexpensively and assists us in developing accurate models in less time, even if we have limited experience and incomplete knowledge for an urban fractured-rock aquifer system affected by storm water infiltration.

Over the past fifteen years many schools have utilized aggression prevention programs. Despite these apparent advances, many programs are not examined systematically to determine the areas in which they are most effective. One reason for this is that many programs, especially those in urban under-resourced areas, do not utilize outcome measures that are sensitive to the needs of ethnic minority students. The current study illustrates how a new knowledge-based measure of social information processing and anger management techniques was designed through a partnership-based process to ensure that it would be sensitive to the needs of urban, predominately African American youngsters, while also having broad potential applicability for use as an outcome assessment tool for aggression prevention programs focusing upon social information processing. The new measure was found to have strong psychometric properties within a sample of urban predominately African American youth, as item analyses suggested that almost all items discriminate well between more and less knowledgeable individuals, that the test-retest reliability of the measure is strong, and that the measure appears to be sensitive to treatment changes over time. In addition, the overall score of this new measure is moderately associated with attributions of hostility on two measures (negative correlations) and demonstrates a low to moderate negative association with peer and teacher report measures of overt and relational aggression. More research is needed to determine the measure's utility outside of the urban school context. PMID:20449645

Aim: The present study was undertaken to understand the zoonotic importance of canine scabies and dermatophytosis with special reference to the knowledge level of dog owners in urban areas of Gujarat. Materials and Methods: The study was carried out in randomly selected 120 dog owners of 3 urban cities (viz., Ahmedabad, Anand and Vadodara) of Gujarat state, India. Dog owners (i.e., respondents) were subjected to a detailed interview regarding the zoonotic importance of canine scabies and dermatophytosis in dogs. Ex-post-facto research design was selected because of the independent variables of the selected respondent population for the study. The crucial method used in collecting data was a field survey to generate null hypothesis (Ho1). Available data was subjected to statistical analysis. Results: The three independent variables, viz., extension contact (r=0.522**), mass-media exposure (r=0.205*) and management orientation (r=0.264**) had significant relationship with knowledge of dog owners about zoonotic diseases. Other independent variables, viz., education, experience in dog keeping and housing space were observed to have negative and non-significant relationship with knowledge of dog owners about zoonotic diseases. Conclusion: Extension contact, exposure to extension mass-media, management orientation and innovation proneness among dog owners of 3 urban cities of Gujarat state had significant relationship with knowledge of dog owners on zoonotic aspects of canine scabies and dermatophytosis. Data provided new insights on the present status of zoonotic disease-awareness, which would be an aid to plan preventive measures. PMID:27065644

Urban boundary is an important indicator for urban sprawl analysis. However, methods of urban boundary extraction were inconsistent, and construction land or urban impervious surfaces was usually used to represent urban areas with coarse-resolution images, resulting in lower precision and incomparable urban boundary products. To solve above problems, a semi-automatic method of urban boundary extraction was proposed by using high-resolution image and geographic information data. Urban landscape and form characteristics, geographical knowledge were combined to generate a series of standardized rules for urban boundary extraction. Urban boundaries of China's 31 provincial capitals in year 2000, 2005, 2010 and 2015 were extracted with above-mentioned method. Compared with other two open urban boundary products, accuracy of urban boundary in this study was the highest. Urban boundary, together with other thematic data, were integrated to measure and analyse urban sprawl. Results showed that China's provincial capitals had undergone a rapid urbanization from year 2000 to 2015, with the area change from 6520 square kilometres to 12398 square kilometres. Urban area of provincial capital had a remarkable region difference and a high degree of concentration. Urban land became more intensive in general. Urban sprawl rate showed inharmonious with population growth rate. About sixty percent of the new urban areas came from cultivated land. The paper provided a consistent method of urban boundary extraction and urban sprawl measurement using high-resolution remote sensing images. The result of urban sprawl of China's provincial capital provided valuable urbanization information for government and public.

To understand the current status of malaria control knowledge awareness of primary and secondary school students and its influencing factors in Yunlong District, Xuzhou City, so as to provide the evidence for improving the malaria prevention work. A total of 800 students from 4 urban and rural primary and secondary schools were randomly selected and investigated with questionnaires. The total awareness rate of malaria control knowledge was 61.27%, and the awareness rates of symptoms of malaria and malaria prevention were only 38.99% and 57.59% respectively. The main approach of obtaining the malaria control knowledge was media (51.52%). The univariate analysis showed that sex, area and different education levels affected the awareness rates of malaria control knowledge (P < 0.05), and the Logistic analysis showed that the awareness rate of malaria control knowledge of country students was lower than that of urban students (P < 0.05), and the awareness rate of malaria control knowledge of the secondary school students was higher than that of the primary school students (P < 0.05). The awareness rate of malaria control knowledge of primary and secondary school students in Yunlong District is lower than that required by the national standard. Therefore, the health education of malaria control should be strengthened, especially in countryside school students and primary school students.

Wortman, Sam E; Lovell, Sarah Taylor

2013-09-01

Urban agriculture, though often difficult to define, is an emerging sector of local food economies in the United States. Although urban and agricultural landscapes are often integrated in countries around the world, the establishment of mid- to large-scale food production in the U.S. urban ecosystem is a relatively new development. Many of the urban agricultural projects in the United States have emerged from social movements and nonprofit organizations focused on urban renewal, education, job training, community development, and sustainability initiatives. Although these social initiatives have traction, critical knowledge gaps exist regarding the science of food production in urban ecosystems. Developing a science-based approach to urban agriculture is essential to the economic and environmental sustainability of the movement. This paper reviews abiotic environmental factors influencing urban cropping systems, including soil contamination and remediation; atmospheric pollutants and altered climatic conditions; and water management, sources, and safety. This review paper seeks to characterize the limited state of the science on urban agricultural systems and identify future research questions most relevant to urban farmers, land-use planners, and environmental consultants.

2009-01-01

Worldwide, the need for transformative change in urban water management is acknowledged by scientists and policy makers. The effects of climate change and developments such as urbanization, the European Water Framework Directive, and societal concerns about the sustainability of urban water system force the sector to adapt. In The Netherlands, a shift towards integration of spatial planning and water management can be observed. Despite major changes in water management policy and approach, changes in the physical urban water management infrastructure remain limited to incremental solutions and demonstration projects. Policy studies show that institutional factors and professional perceptions are important factors for application of innovations in urban water management. An online survey among Dutch urban water management professionals demonstrates that according to most respondents, optimization of the current system is sufficient to achieve both European and national objectives for sustainable urban water management. The respondents are most concerned with the effects of climate change on urban water systems. In contrast to current policy of the national government, priority factors that should be addressed to achieve a more sustainable urban water system are improving knowledge of local urban water systems, capacity building, developing trust between stakeholders, and improving involvement of elected officials and citizens.

The knowledge of the distribution of rainfall in mountain environments Mediterranean is still very complex and requires a comprehensive monitoring and appropriate analytical techniques - statistics to be scientifically valid and easily communicable. The Isonzo's basin - located between Slovenia and Italy within the Julian Alps - has characteristics meteoric absolutely uncommon, revealing the wettest of entire southern side of the Alps. Nonetheless, the climatological studies of detail are very rare; resulting an insufficient knowledge of specific themes, a lack of information for the purpose of territorial planning and especially the development of forecasting future scenarios according to the IPCC guidelines. The lower valley bottom of the Soca river is particularly urbanized and cultivated and the numerous, short minor streams - such as Corno and Versotizza - run within the city of Nova Gorica and Gorizia and their industrial areas. Their torrential regime can cause a flood events in relation to the intensity of more irregular and often very abundant rainfall. In this regard, the meteorological year 2014, was the wettest and perturbed the last thirty years in the whole mountain sector of the Isonzo basin, with punctual values ranging between about 2150 mm in Gorizia and 5600 mm in Musi di Udine, compared to their respective averages of 1400 and 3000 mm in the 1981-2010 period. The high frequency of days with precipitation sufficient to cause local flooding and floods from the minor watercourses is significant increase in recent years; consequently must be considered some fundamental aspects in the planning of little space land not yet urbanized and in the exploitation of agricultural and trade resources - heart of the local economy - increasingly exposed to the floods risk. This study aims to provide a thorough knowledge of the precipitation context of the urban agglomeration of Gorizia - Nova Gorica and its significant around; so to be provided the necessary knowledge to a hydraulic design of that allows the complete safety measures in existing production sites and the correct design of urban areas not yet built up through an comprehensive and precise definition of the areas at flood risk.

Influence of gender roles and rising food prices on poor, pregnant women's eating and food provisioning practices in Dhaka, Bangladesh.

Levay, Adrienne V; Mumtaz, Zubia; Faiz Rashid, Sabina; Willows, Noreen

2013-09-26

Maternal malnutrition in Bangladesh is a persistent health issue and is the product of a number of complex factors, including adherence to food 'taboos' and a patriarchal gender order that limits women's mobility and decision-making. The recent global food price crisis is also negatively impacting poor pregnant women's access to food. It is believed that those who are most acutely affected by rising food prices are the urban poor. While there is an abundance of useful quantitative research centered on maternal nutrition and food insecurity measurements in Bangladesh, missing is an understanding of how food insecurity is experienced by people who are most vulnerable, the urban ultra-poor. In particular, little is known of the lived experience of food insecurity among pregnant women in this context. This research investigated these lived experiences by exploring food provisioning strategies of urban, ultra-poor, pregnant women. This knowledge is important as discussions surrounding the creation of new development goals are currently underway. Using a focused-ethnographic approach, household food provisioning experiences were explored. Data from participant observation, a focus group discussion and semi-structured interviews were collected in an urban slum in Dhaka, Bangladesh. Interviews were undertaken with 28 participants including 12 pregnant women and new mothers, two husbands, nine non-pregnant women, and five health care workers. The key findings are: 1) women were aware of the importance of good nutrition and demonstrated accurate, biomedically-based knowledge of healthy eating practices during pregnancy; 2) the normative gender rules that have traditionally constrained women's access to nutritional resources are relaxing in the urban setting; however 3) women are challenged in accessing adequate quality and quantities of food due to the increase in food prices at the market. Rising food prices and resultant food insecurity due to insufficient incomes are negating the recent efforts that have increased women's knowledge of healthy eating during pregnancy and their gendered empowerment. In order to maintain the gains in nutritional knowledge and women's increased mobility and decision-making capacity; policy must also consider the global political economy of food in the creation of the new development goals.

The understanding of the public's knowledge on human cloning (HC) and its acceptability are considered important for the development of evidence-based policy making. The aim of this research study was to investigate the demographic and socioeconomic variables that affect the public's knowledge and intention to use HC in urban areas of Greece. Additionally, the possible association of religiousness with the knowledge and the intention to use HC were also investigated. Individual interviews were conducted with 1020 men and women of urban areas in Greece. Stratified random sampling was performed to select the respondents. Several scientists, experts in HC, evaluated the content of the instrument initially developed. The final questionnaire was consequently the result of a pilot study. Almost half of the respondents (51.5%) believed that "HC is a sort of in vitro fertilization" and 42.9% that "it has already been applied to human being." They were not aware that "the cloned fetus grows in the woman's uterus" (41.5%) and that "HC could regenerate human organs" (41.7%). The acceptability of human cloning for the cure of terminal diseases and transplantation need is very high (70.7% and 58.6%, respectively). The public's intention to have recourse to cloning on the grounds of "bringing" back to life a loved person or because of reproductive disorders was reported as desire by 35% and 32.5%, respectively. The occupational category (scientists, self-employed, and artists), the Intention to use HC, and the number of children are highly significant predictors of valid knowledge about HC. Low rates of church attendance appeared to relate with high reported Intention to use HC, and increasing scores of valid knowledge about HC increased the public's Intention to use HC. A number of specific demographic and socioeconomic characteristics and high scores of knowledge provide a persuasive justification in demonstrating intention toward HC. The current study suggests that these findings should receive further attention by policymakers and scientists within the Greek context.

Health, illness, and healing in an uncertain era: challenges from and for medical sociology.

PubMed

Pescosolido, B A; Kronenfeld, J J

1995-01-01

The current situation in health care organizations, among providers and for people, dramatically challenges the "business as usual" roles of medicine, government, insurance companies, the community, and the university. Health care reform marks the first attempt in a century to consider a reconstruction of the social contract between society and medicine. While sociology stands as one of the earliest social sciences to systematically study the health care arena and create a health-focused subfield, there is a perception, not without support, of a desertion of identity from within, an encroachment by other areas from without, and abandonment by the parent discipline. We argue that these situations in medical arenas and in research fields require serious rethinking. The key lies in understanding how these phenomena are related to each other and to larger social forces, and how they offer opportunities, rather than signal limitations, to medical sociologists. We turn to the theoretical tools of sociology to help unravel the complicated challenges that face both policymakers and researchers. After framing these issues in a sociology of knowledge perspective, we use the case of "utilization theory" to illustrate the connections between society and systems of care (as well as studies of them) and to create a future agenda. We end by raising three basic questions: (1) Why is a sociological perspective critical to the understanding of change and reform in health care? (2) Why is medical sociology critical to the survival of the general sociological enterprise? and (3) Why is general sociology critical to the research agenda in medical sociology?

This paper presents a holistic approach to sustainable urban brownfield redevelopment where specific focus is put on the integration of a multitude of subsurface qualities in the early phases of the urban redevelopment process, i.e. in the initiative and plan phases. Achieving sustainability in brownfield redevelopment projects may be constrained by a failure of engagement between two key expert constituencies: urban planners/designers and subsurface engineers, leading to missed opportunities and unintended outcomes in the plan realisation phase. A more integrated approach delivers greater benefits. Three case studies in the Netherlands, Belgium and Sweden were used to test different sustainability assessment instruments in terms of the possibility for knowledge exchange between the subsurface and the surface sectors and in terms of cooperative learning among experts and stakeholders. Based on the lessons learned from the case studies, a generic decision process framework is suggested that supports holistic decision making. The suggested framework focuses on stakeholder involvement, communication, knowledge exchange and learning and provides an inventory of instruments that can support these processes.

This review comprehensively examines scientific literature pertaining to human physiology during exercise, including mechanisms of heat formation and dissipation, heat stress on the body, the importance of skin temperature monitoring, the effects of clothing, and microclimatic measurements. This provides a critical foundation for microclimatologists and biometeorologists in the understanding of experiments involving human physiology. The importance of the psychological aspects of how an individual perceives an outdoor environment are also reviewed, emphasizing many factors that can indirectly affect thermal comfort (TC). Past and current efforts to develop accurate human comfort models are described, as well as how these models can be used to develop resilient and comfortable outdoor spaces for physical activity. Lack of suitable spaces plays a large role in the deterioration of human health due to physical inactivity, leading to higher rates of illness, heart disease, obesity and heat-related casualties. This trend will continue if urban designers do not make use of current knowledge of bioclimatic urban design, which must be synthesized with physiology, psychology and microclimatology. Increased research is required for furthering our knowledge on the outdoor human energy balance concept and bioclimatic design for health and well-being in urban areas.

Emissions of carbon associated with cities comprise a large component of the anthropogenic source. A number of cities have announced plans to reduce greenhouse gas emissions, but the scientific knowledge to quantitatively track emissions and assess the efficacy of mitigation is lacking. As the global population increasingly resides in urban regions, scientific knowledge about how much, where, and why a particular city emits carbon becomes increasingly important. To address this gap, researchers have initiated studies of carbon emissions and cycling in several U.S. cities, making it timely to develop a collaborative network to exchange information on community standards and common measurements, facilitate data sharing, and create analysis frameworks and cross-city syntheses to catalyze a new generation of researchers and enable new collaborations tackling important objectives that are difficult to address in isolation. We describe initial results from an incipient network focusing initially on cities in the U.S. with low barriers of entry that entrains a cross-section of U.S. urban centers with varying characteristics: size, population density, vegetation, urban form, infrastructure, development rates, climate, and meteorological patterns. Results will be reported that emerge from an initial workshop covering data harmonization & integration, inventory comparison, stakeholder outreach, network design, inverse modeling, and collaboration.

Murphy, Kelly; Fafard, Patrick; O'Campo, Patricia

2012-12-01

In 2011, an interdisciplinary symposium was organized in Toronto, Canada to investigate prevailing models of health policy change in the knowledge translation literature and to assess the applicability of these models for equity-focused urban health research. The papers resulting from the symposium have been published together, in the Journal of Urban Health, along with this introductory essay. This essay describes how the different papers grapple in different ways with how to understand and to bridge the gaps between urban health research and action. The breadth of perspectives reflected in the papers (e.g., social epidemiology, public health, political science, sociology, critical labor studies, and educational psychology) shed much light on core tensions in the relationship between KT and health equity. The first tension is whether the content of evidence or the context of decision making is the strong determinate of research impact in relation to health equity policy. The second tension is whether relationships between health equity researchers and decision makers are best viewed in terms of collaboration or of conflict. The third concerns the role that power plays in evidence-based policy making, when the issues at stake are not only empirical but also normative.

Anthropogenic impacts on continental margins: New frontiers and engagement arena for global sustainability research and action

There is an urgent need to design and implement transformative governance strategies that safeguard Earth's life-support systems essential for long-term human well-being. From a series of meetings of the Continental Margins Working Group co-sponsored by IMBER and LOICZ of IGBP, we conclude that the greatest urgency exists at the ocean-land interface - the continental margins or the Margin - which extends from coastlands over continental shelves and slopes bordering the deep ocean. The Margin is enduring quadruple squeeze from (i) Population growth and rising demands for resources; (ii) Ecosystem degradation and loss; (iii) Rising CO2, climate change and alteration of marine biogeochemistry and ecosystems; and (iv) Rapid and irreversible changes in social-ecological systems. Some areas of the Margin that are subject to the greatest pressures (e.g. the Arctic) are also those for which knowledge of fundamental processes remains most limited. Aside from improving our basic understanding of the nature and variability of the Margin, priority issues include: (i) investment reform to prevent lethal but profitable activities; (ii) risk reduction; and (iii) jurisdiction, equity and fiscal responsibility. However, governance deficits or mismatches are particularly pronounced at the ocean-edge of the Margin and the prevailing Law of the Sea is incapable of resolving these challenges. The "gold rush" of accelerating demands for space and resources, and variability in how this domain is regulated, move the Margin to the forefront of global sustainability research and action. We outline a research strategy in 3 engagement arenas: (a) knowledge and understanding of dynamic Margin processes; (b) development, innovation and risk at the Margin; and (c) governance for sustainability on the Margin. The goals are (1) to better understand Margin social-ecological systems, including their physical and biogeochemical components; (2) to develop practical guidance for sustainable development and use of resources; (3) to design governance regimes to stem unsustainable practices; (4) to investigate how to enable equitable sharing of costs and benefits from sustainable use of resources; and (5) to evaluate alternative research approaches and partnerships that address the challenges faced on the Margin.

Food (In)Security in Rapidly Urbanising, Low-Income Contexts.

Tacoli, Cecilia

2017-12-11

Urbanisation in low and middle-income nations presents both opportunities and immense challenges. As urban centres grow rapidly, inadequate housing and the lack of basic infrastructure and services affect a large and growing proportion of their population. There is also a growing body of evidence on urban poverty and its links with environmental hazards. There is, however, limited knowledge of how these challenges affect the ways in which poor urban residents gain access to food and secure healthy and nutritious diets. With some important exceptions, current discussions on food security continue to focus on production, with limited attention to consumption. Moreover, urban consumers are typically treated as a homogenous group and access to food markets is assumed to be sufficient. This paper describes how, for the urban poor in low and middle-income countries, food affordability and utilisation are shaped by the income and non-income dimensions of poverty that include the urban space.

China has seen the largest human migration in history, and the country's rapid urbanisation has important consequences for public health. A provincial analysis of its urbanisation trends shows shifting and accelerating rural-to-urban migration across the country and accompanying rapid increases in city size and population. The growing disease burden in urban areas attributable to nutrition and lifestyle choices is a major public health challenge, as are troubling disparities in health-care access, vaccination coverage, and accidents and injuries in China's rural-to-urban migrant population. Urban environmental quality, including air and water pollution, contributes to disease both in urban and in rural areas, and traffic-related accidents pose a major public health threat as the country becomes increasingly motorised. To address the health challenges and maximise the benefits that accompany this rapid urbanisation, innovative health policies focused on the needs of migrants and research that could close knowledge gaps on urban population exposures are needed.

In this work, we explore the spatial structure of built zones and green areas in diverse western cities by analyzing the probability distribution of areas and a coefficient that characterize their respective shapes. From the analysis of diverse datasets describing land lots in urban areas, we found that the distribution of built-up areas and natural zones in cities obey inverse power laws with a similar scaling for the cities explored. On the other hand, by studying the distribution of shapes of lots in urban regions, we are able to detect global differences in the spatial structure of the distribution of land. Our findings introduce information about spatial patterns that emerge in the structure of urban settlements; this knowledge is useful for the understanding of urban growth, to improve existing models of cities, in the context of sustainability, in studies about human mobility in urban areas, among other applications.

Notes from California: an anthropological approach to urban science education for language minority families

This article describes a unique and ongoing collaboration involving a team of bilingual/multicultural teacher-educators, preservice teachers, teachers, students, and community members in an urban California elementary school. According to the model this team employed, children, teachers, and student teachers gather community funds of knowledge about the science to be studied in a classroom, then incorporate this knowledge by using parents as experts and by creating community books. In this model community-generated materials parallel and complement standards-based curricula, although science topics that have natural significance in particular communities are used as a starting point. Using critical ethnography as a framework, the article focuses on a particular experience - the building of a Mien-American garden house - to show how, by drawing on participants' funds of knowledge, a new kind of multiscience can emerge, one accessible to all collaborating members and responsive to school standards.

Theoretical models suggest that both HIV knowledge and HIV risk perception inform rational decision making and, thus, predict safer sex motivation and behavior. However, the amount of variance explained by knowledge and risk perception is typically small. In this cross-sectional study, we investigated whether the predictive power of HIV knowledge and HIV risk perception on safer sex motivation is affected by trait anger. We hypothesized that anger may disrupt rational decision making, distorting the effects of both HIV knowledge and risk perception on safer sex intentions. Data from 232 low-income, urban women at risk for HIV infection were used to test a path model with past sexual risk behavior, HIV knowledge, and HIV risk perception as predictors of safer sex intentions. Moderator effects of anger on safer sex intentions were tested by simultaneous group comparisons between high-anger and low-anger women (median split). The theoretically expected "rational pattern" was found among low-anger women only, including (a) a positive effect of knowledge on safer sex intentions, and (b) buffer (inhibitor) effects of HIV knowledge and HIV risk perception on the negative path leading from past risk behavior to safer sex intentions. Among high-anger women, an "irrational pattern" emerged, with no effects of HIV knowledge and negative effects of both past risk behavior and HIV risk perception on safer sex intentions. In sum, the results suggest that rational knowledge- and risk-based decisions regarding safer sex may be limited to low-anger women.

This study tested the feasibility of a combined microcredit and life-skills HIV prevention intervention among 50 adolescent female orphans in urban/peri-urban Zimbabwe. Quantitative and qualitative data were collected on intervention delivery, HIV knowledge and behavior, and economic indicators. The study also tested for HIV, HSV-2, and pregnancy. At 6 months, results indicated improvements in knowledge and relationship power. Because of the economic context and lack of adequate support, however, loan repayment and business success was poor. The results suggest that microcredit is not the best livelihood option to reduce risk among adolescent girls in this context.

This article reports on the development of HTML5 based web-content related to urban modelling with special focus on GML and CityGML, allowing participants to access it regardless of the device platform. An essential part of the learning modules are short video lectures, supplemented by exercises and tests during the lecture to improve students' individual progress and success. The evaluation of the tests is used to guide students through the course content, depending on individual knowledge. With this approach, we provide learning applications on a wide range of devices, either mobile or desktop, fulfil the needs of just-in-time knowledge, and increase the emphasis on lifelong learning.

Analysing the impact of urban areas patterns on the mean annual flow of 43 urbanized catchments

It is often argued that urban areas play a significant role in catchment hydrology, but previous studies reported disparate results of urbanization impacts on stream flow. This might stem either from the difficulty to quantify the historical flow changes attributed to urbanization only (and not climate variability) or from the inability to decipher what type of urban planning is more critical for flows. In this study, we applied a hydrological model on 43 urban catchments in the United States to quantify the flow changes attributable to urbanization. Then, we tried to relate these flow changes to the changes of urban/impervious areas of the catchments. We argue that these spatial changes of urban areas can be more precisely characterized by landscape metrics, which enable analysing the patterns of historical urban growth. Landscape metrics combine the richness (the number) and evenness (the spatial distribution) of patch types represented on the landscape. Urbanization patterns within the framework of patch analysis have been widely studied but, to our knowledge, previous research works had not linked them to catchments hydrological behaviours. Our results showed that the catchments with larger impervious areas and larger mean patch areas are likely to have larger increase of runoff yield.

The Urban Ecology Institute's field studies program: utilizing urban areas for experiential learning and ecological research

The Urban Ecology Institute (UEI) promotes the stewardship of healthy urban ecosystems by improving science and civic education for middle and high school youth and by working with urban communities to protect and transform natural resources. Established in 1999, UEI's field studies program engages over 1000 youth in the greater Boston area. A substantial component of this program involves water quality monitoring. We have recently adapted protocols from published leaf breakdown studies for incorporation into the UEI water quality curriculum. A 2004 pilot study of these leaf breakdown activities, conducted at four sites, compared rates of red maple breakdown to those of Norway maple, a potentially invasive urban street tree. Preliminary data from this successful pilot study suggest that leaf litter inputs from the two different tree species have varying effects on stream ecosystem function. We present this study as an example of how urban areas can be utilized for both ecological research and inclusive experiential learning through which science and mathematic knowledge can be effectively communicated.
