    In the present study, the concentrations and proportions of perfluoroalkyl substances (PFASs) in water and sediments (in different seasons) from the Qing River were investigated. The highest concentration of PFASs in water (207.59 ng L(-1)) was found in summer. The composition of PFASs in water changed with time, perfluorobutane sulfonate (PFBS) was the predominant compound in spring and summer, while long-chain PFASs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), started to increase in autumn and winter. The PFASs concentration in sediments ranged from 0.96 to 4.05 ng g(-1) dw. The proportion of long-chain PFASs was higher than that of short-chain PFASs in sediments, the dominant component in sediments was PFOA with a contribution of 24.6-75.4% to total PFASs in sediments, followed by PFOS. The concentrations of PFASs in roots of emergent plants were relatively higher than those in submerged plants. However, the translocation effect of PFASs was not remarkable. Bioaccumulation factors (BAFs) of the aquatic plants indicated the absorption of PFASs were effective. BAFs in submerged plants basically increased with increasing chain length accordingly. In general, aquatic plants had the absorption preference for long-chain PFASs, especially PFOS, which was the predominant compounds in both submerged and emergent plants. Based on the results above, hornworts were selected to be cultivated indoor in the nutrient solution spiked gradient concentrations of PFOS to assess the general ecological risk. The results revealed that hornworts were resistant to PFOS and might be used as remediation flora to eliminate PFOS contamination.

    In recent years, many researchers study on the relation between culture and language, language and translation, or culture and translation. Indeed, the three subjects are inseparable. It's incomprehensive to look into just two of them for a linguist. It's more useful for us to study on the relation between them, because we can extend our eyesight and searching scope and propel our translation business. Moreover, studying on them provides a rich material for other fields, such as sociology, translation, cross-cultural communication as well as give other subjects a lead to deep further.

    2014-07-01

    Full Text Available This conceptual paper offers insights to the foundations of Socio-Cultural Ecology and relates this concept to traditional concepts of Ecology e.g. media ecology or Bronfenbrenner’s ecological model of child development. It will further discuss the term «ecology» as a relation between learners and their surrounding physical and structural world, e. g. an ecology of resources or the classroom as an ecological system. Thirdly more recent concepts in ecology will be considered e. g. Digital Media Ecology including media ecology (German: Medienökologie from a German perspective. This contribution tries to describe common principles of (media ecologies and will ask after their meaning and relation to media education and mobile learning. One of the main results is the realisation that cultural practices of school learning and cultural practices of media acquisition take place in different worlds or in different ecological spheres. The question is thus again of how to bridge these ecological spheres, and how «agency» developed outside school, can be nourished inside school. In other words: how can we bridge socio-cultural and technological structures within these cultural practices.

  8. The ecology of primate material culture.

    Koops, Kathelijne; Visalberghi, Elisabetta; van Schaik, Carel P

    2014-11-01

    Tool use in extant primates may inform our understanding of the conditions that favoured the expansion of hominin technology and material culture. The 'method of exclusion' has, arguably, confirmed the presence of culture in wild animal populations by excluding ecological and genetic explanations for geographical variation in behaviour. However, this method neglects ecological influences on culture, which, ironically, may be critical for understanding technology and thus material culture. We review all the current evidence for the role of ecology in shaping material culture in three habitual tool-using non-human primates: chimpanzees, orangutans and capuchin monkeys. We show that environmental opportunity, rather than necessity, is the main driver. We argue that a better understanding of primate technology requires explicit investigation of the role of ecological conditions. We propose a model in which three sets of factors, namely environment, sociality and cognition, influence invention, transmission and retention of material culture.

    Social and Natural sciences have, for the most part, ignored the existence of interlinked/interdependent evolutionary processes between cultural and biotic systems, both embedded in an overall dynamic biophysical environment. In this paper, we explore the potential of filling this gap by further developing a common coevolutionary framework based on earlier work in ecological economics. Our main concern is to contribute to the understanding of socioecological coevolution in two ways: (1) to find a general framework that accommodates advances in the explanation of sociocultural evolution in social sciences and, (2) to identify the specific mechanisms that could link this knowledge to what is known in the biological sciences.

    Full Text Available The ecological security of our country, the possibility of a balanced sustainable development depends on the level of formation of ecological culture of society. Purpose of the article is to analyze the ethnic origins of ecological culture of modern Ukrainian. Nature of Ukraine is the most important point of the historical development of the national character. The installation, stereotypes, archetypes influence on its formation. The aesthetic human needs are met first in the perception of the beauty of unspoiled nature, its comprehension, reflection on the eternal themes: man's place in the natural world, awareness of human relationships and nature, its impact on the individual, man's relation to the world; an effort to recreate the beauty of the surrounding environment. Development of individual aesthetic needs, a sense of harmony and disharmony is the first step of the creativity development, the creative personality possibilities, creativity abilities, which is urgently needed as a modern social development and personal improvement. This is a necessary component of ecological consciousness, ecological culture of modern man.

    With the sudden change of the political structure in the world and the acceleration of the globalization, the impact of culture on diplomacy is becoming increasingly obvious. Especially some conflicts in the diplomacy have made it more important to study and analyze the international relations from a cultural perspective. Culture can be the cause of misunderstanding in diplo⁃matic negotiation, but it can also be a very useful tool and instrument for global public diplomacy. Culture as a“soft power”should be used as the key in the diplomacy to bridge the cultural gaps, reduce conflict and misunderstanding and lead to the com⁃mon goal of peace and development.

  17. Bridging the lab-field divide? The "eco" in ecological genomics.

    Science.gov (United States)

    van der Hout, Sanne

    2013-01-01

    The emerging field of ecological genomics promises to bring about a marriage between ecological and laboratory-based, genomic investigations. In this paper, I will reflect on this promise by exploring how ecology and genomics are integrated in the two approaches that currently dominate this field: the organism-centred approach, focusing on individual (model) organisms, and the metagenomic approach, concentrating on (the metagenome of) entire microbial communities composed of a variety of species. I will show that both approaches have already taken some important steps in bridging the gap between genomics and ecology. Since the introduction of next-generation sequencing methodology in 2007, the organism-centred approach does not need to stick to classical model organisms like Arabidopsis anymore. Instead, it is now able to apply genomic tools to ecologically interesting species (e.g. amphibians, reptiles, birds) as well. The metagenomic approach has been able to give ecology a more prominent place in its investigations, in another way. Contrary to classical microbiology (the field from which it originates), it does not study microbial communities under controlled laboratory settings, but under nature's own conditions. However, in the marriage between genomics and ecology, genomics still appears to be the dominant partner, especially in the case of the organism-centred approach that continues to study the new ecological models in artificial lab environments. Moreover, the organism-centred and metagenomic approaches employ a gene-centred perspective in understanding critical ecological interactions, thus strengthening a reductionist rather than a holistic (systems-oriented) approach.

  18. Cultural psychology as a bridge between anthropology and cognitive science.

    Fryberg, Stephanie A

    2012-07-01

    The theory and methods of cultural psychology begin with the assumption that psychological processes are socioculturally and historically grounded. As such, they offer a new approach for understanding the diversity of human functioning because they (a) question the presumed neutrality of the majority group perspective; (b) take the target's point-of-view (i.e., what it means to be a person in a particular context); (c) assume that there is more than one viable way of being a competent or effective person; and (d) provide a road map for understanding and reducing social inequities. As illustrated in this essay, a cultural psychological approach provides a bridge between anthropology and the cognitive sciences, and in so doing it offers an alternative set of explanations and interventions for group differences.

    2016-11-01

    Midwifery educators and regulators in Canada have begun to address diversity, equity, and inclusion in admission processes and program curricula. Populations served by midwives value internationally educated midwives from their countries of origin. The International Midwifery Pre-Registration Program at Ryerson University in Toronto, Ontario, provides assessment, midwifery workplace orientation, and accelerated education for internationally educated midwives on behalf of the regulatory College of Midwives of Ontario. Between 2003 and 2015, midwives from 41 countries participated in the bridging program, and 214 (80%) successfully completed the program and qualified for licensure. Of these 214 graduates, 100% passed the Canadian Midwifery Registration Examination and 193 (90%) were employed full time as midwives within 4 months of graduation. The program curriculum enables the integration of these midwives into health care workplaces utilizing innovative approaches to assessment and competency enhancement. Critical to the bridging process are simulation-based practices to develop effective psychomotor learning, virtual and real primary care community placements, and coaching in empathetic, client-centered communication. Cultural sensitivity is embedded into the multiple assessment and learning modalities, and addresses relevant barriers faced by immigrant midwives in the workplace. Findings from the 13 years of the program may be applicable to increase diversity in other North American midwifery settings. This article describes the process, content, outcomes, and findings of the program. Midwifery educators and regulators may consider the utility of these approaches for their settings.

  2. Art and artistic processes bridge knowledge systems about social-ecological change: An empirical examination with Inuit artists from Nunavut, Canada

    2016-06-01

    Full Text Available The role of art and artistic processes is one fruitful yet underexplored area of social-ecological resilience. Art and art making can nurture Indigenous knowledge and at the same time bridge knowledge across generations and cultures (e.g., Inuit and scientific. Experiences in two Inuit communities in northern Canada (Cape Dorset and Pangnirtung, Nunavut provide the context in which we empirically examine the mechanisms through which art and art making may bridge knowledge systems about social-ecological change. Art making and artworks create continuity between generations via symbols and skill development (e.g., seal skin stretching for a modern artistic mural and by creating mobile and adaptive boundary objects that function as a shared reference point to connect different social worlds. Our results indicate how art and artistic processes may bridge knowledge systems through six mechanisms, and in so doing contribute to social-ecological resilience during change and uncertainty. These mechanisms are (1 embedding knowledge, practice and belief into art objects; (2 sharing knowledge using the language of art; (3 sharing of art making skills; (4 art as a contributor to monitoring social-ecological change; (5 the role of art in fostering continuity through time; and (6 art as a site of knowledge coproduction.

    Planting-culturing system in inter-tidal zone is a new type eco-culturing model. The survey on bacteria biomass and water quality in the designed planting-culturing system in inter-tidal zone showed that the mangrove planted in the system improved water quality and made water quality to II-III type, better than the IV and V type in the control pond. Designed ponds made heterotrophic bacteria, vibrio, phosphorus bacteria and enzyme-producing bacteria populations 1-2 order lower than the control pond without mongrove planting. Correlation analyses with CORREL software showed that the biomass of these bacteria was positively related with the nitrogen and phosphorus contents in water of the system, and the correlation coefficient for heterogeneous bacteria and vibrio was up to 0.9205. Heterotrophic bacteria and vibrio could be used as the water-quality monitoring organisms.

The practical application of Steward’s theories to the processes of Mexican regional formation, linked to the use of hydraulic technologies as part of both adaptative cultural strategies and the political control of water in the process of food production, shows that Cultural Ecology, understood as cultural management of natural environments, as it happens with Economy, is designed and politically manipulated in the context of deeply unequal societies with unadaptative consequences.

  11. Introductory biology and ecological literacy: A critical cultural analysis

    Science.gov (United States)

    Kellogg, Joseph Damian

    Despite the lack of accepted standards for the introductory biology course for students majoring in biology, the content and format of the first-year biology course is remarkably uniform in terms of both curriculum and pedagogy. This investigation is a critical cultural analysis of the purpose of, and practices within, undergraduate biology education in general, and the introductory biology course in particular. Drawing on a theoretical framework that combines critical philosophical inquiry, ecological literacy, science studies, and cultural studies, I argue that the failure of biology educators within the university to acknowledge the diversity of their student body and to actively engage social and ecological issues has resulted in a curriculum that has almost no meaning for students, and that is socially and ecologically irresponsible. This work is a search for meaningful alternatives. Within this work, I attempt to provide biology educators, as well as would-be reformers, with a seldom-seen view of academic biology. This is done to unsettle the status quo, and to initiate processes of seeking out spaces for change. Through the discourses of critical pedagogy and ecological literacy I examine the laboratories, lecture halls, teaching practices, and course materials that students encounter as they experience "the study of life." Additionally, I place the genesis and evolution of the introductory biology course within the sociohistorical context of reform in science education and academic biology in an effort to explain the amazing and problematic stability of this course.

  13. Forests, savannas and grasslands: bridging the knowledge gap between ecology and Dynamic Global Vegetation Models

    Directory of Open Access Journals (Sweden)

    M. Baudena

    2014-06-01

    Full Text Available The forest, savanna, and grassland biomes, and the transitions between them, are expected to undergo major changes in the future, due to global climate change. Dynamic Global Vegetation Models (DGVMs are very useful to understand vegetation dynamics under present climate, and to predict its changes under future conditions. However, several DGVMs display high uncertainty in predicting vegetation in tropical areas. Here we perform a comparative analysis of three different DGVMs (JSBACH, LPJ-GUESS-SPITFIRE and aDGVM with regard to their representation of the ecological mechanisms and feedbacks that determine the forest, savanna and grassland biomes, in an attempt to bridge the knowledge gap between ecology and global modelling. Model outcomes, obtained including different mechanisms, are compared to observed tree cover along a mean annual precipitation gradient in Africa. Through these comparisons, and by drawing on the large number of recent studies that have delivered new insights into the ecology of tropical ecosystems in general, and of savannas in particular, we identify two main mechanisms that need an improved representation in the DGVMs. The first mechanism includes water limitation to tree growth, and tree-grass competition for water, which are key factors in determining savanna presence in arid and semi-arid areas. The second is a grass-fire feedback, which maintains both forest and savanna occurrences in mesic areas. Grasses constitute the majority of the fuel load, and at the same time benefit from the openness of the landscape after fires, since they recover faster than trees. Additionally, these two mechanisms are better represented when the models also include tree life stages (adults and seedlings, and distinguish between fire-prone and shade-tolerant savanna trees, and fire-resistant and shade-intolerant forest trees. Including these basic elements could improve the predictive ability of the DGVMs, not only under current climate

  15. Extraordinary sex ratios: cultural effects on ecological consequences.

    Directory of Open Access Journals (Sweden)

    Ferenc Molnár

    Full Text Available We model sex-structured population dynamics to analyze pairwise competition between groups differing both genetically and culturally. A sex-ratio allele is expressed in the heterogametic sex only, so that assumptions of Fisher's analysis do not apply. Sex-ratio evolution drives cultural evolution of a group-associated trait governing mortality in the homogametic sex. The two-sex dynamics under resource limitation induces a strong Allee effect that depends on both sex ratio and cultural trait values. We describe the resulting threshold, separating extinction from positive growth, as a function of female and male densities. When initial conditions avoid extinction due to the Allee effect, different sex ratios cannot coexist; in our model, greater female allocation always invades and excludes a lesser allocation. But the culturally transmitted trait interacts with the sex ratio to determine the ecological consequences of successful invasion. The invading female allocation may permit population persistence at self-regulated equilibrium. For this case, the resident culture may be excluded, or may coexist with the invader culture. That is, a single sex-ratio allele in females and a cultural dimorphism in male mortality can persist; a low-mortality resident trait is maintained by father-to-son cultural transmission. Otherwise, the successfully invading female allocation excludes the resident allele and culture and then drives the population to extinction via a shortage of males. Finally, we show that the results obtained under homogeneous mixing hold, with caveats, in a spatially explicit model with local mating and diffusive dispersal in both sexes.

    Tate, Denise M

    2003-01-01

    The healthcare environment is undergoing rapid change. Healthcare settings have shifted from acute care to encompass a variety of other locations. The healthcare work force is changing from a common ethnic origin to include a multitude of ethnic and racial groups. The patient population also embraces a plethora of different cultural backgrounds. By the year 2080, an estimated 51.1% of the population will be composed mostly of Hispanics, followed by African Americans and Asians. This dynamic transformation has created a critical need for nurses to become more knowledgeable and culturally aware to care for and work with people of other cultures. This article attempts to sensitize nurses to the important roles culture and ethnicity play in the delivery of optimal nursing care. The domain of intercultural communication and its importance in providing culturally competent, patient-relevant care is discussed.

    2016-01-01

    Odonata (dragonflies and damselflies) present an unparalleled insect model to integrate evolutionary genomics with ecology for the study of insect evolution. Key features of Odonata include their ancient phylogenetic position, extensive phenotypic and ecological diversity, several unique evolutionary innovations, ease of study in the wild and usefulness as bioindicators for freshwater ecosystems worldwide. In this review, we synthesize studies on the evolution, ecology and physiology of odonates, highlighting those areas where the integration of ecology with genomics would yield significant insights into the evolutionary processes that would not be gained easily by working on other animal groups. We argue that the unique features of this group combined with their complex life cycle, flight behaviour, diversity in ecological niches and their sensitivity to anthropogenic change make odonates a promising and fruitful taxon for genomics focused research. Future areas of research that deserve increased attention are also briefly outlined.

  9. Sampling in ecology and evolution - bridging the gap between theory and practice

    Sampling is a key issue for answering most ecological and evolutionary questions. The importance of developing a rigorous sampling design tailored to specific questions has already been discussed in the ecological and sampling literature and has provided useful tools and recommendations to sample and analyse ecological data. However, sampling issues are often difficult to overcome in ecological studies due to apparent inconsistencies between theory and practice, often leading to the implementation of simplified sampling designs that suffer from unknown biases. Moreover, we believe that classical sampling principles which are based on estimation of means and variances are insufficient to fully address many ecological questions that rely on estimating relationships between a response and a set of predictor variables over time and space. Our objective is thus to highlight the importance of selecting an appropriate sampling space and an appropriate sampling design. We also emphasize the importance of using prior knowledge of the study system to estimate models or complex parameters and thus better understand ecological patterns and processes generating these patterns. Using a semi-virtual simulation study as an illustration we reveal how the selection of the space (e.g. geographic, climatic), in which the sampling is designed, influences the patterns that can be ultimately detected. We also demonstrate the inefficiency of common sampling designs to reveal response curves between ecological variables and climatic gradients. Further, we show that response-surface methodology, which has rarely been used in ecology, is much more efficient than more traditional methods. Finally, we discuss the use of prior knowledge, simulation studies and model-based designs in defining appropriate sampling designs. We conclude by a call for development of methods to unbiasedly estimate nonlinear ecologically relevant parameters, in order to make inferences while fulfilling requirements of

    Science.gov (United States)

    Williams, Nombasa

    2010-03-01

    Currently an ecological model for conceptualizing and capturing the refugee parenting experience is lacking. After an extensive review of the literature related to the usages of Bronfenbrenner's ecological model of child development, a gap was found in knowledge and research centred on describing the environment of pre-resettlement (i.e. pre-flight, flight, migration, camp) contexts and their impact on refugee parents and carer experiences. The culture of the refugee parenting experience may be characterized by disruptions in and alterations to family structure and organization; values and norms; and gender roles. This paper begins by examining the definition and usages of existing ecological frameworks in the 20th and 21st century. Particular attention is drawn to the gaps in the existing literature and an ecological model is offered. The paper concludes with a discussion of the implications for practice. The outcomes of this paper suggest the need for practitioners, policymakers and researchers to engage and develop culturally competent, relevant and appropriate interventions (i.e. reconciling differing beliefs and behaviours concerning child-rearing practices; affirming positive parenting practices of these families during engagement protocols and processes; adopting a strengths-based orientation) in the area of child protection whilst at the same time safeguarding and promoting the welfare of children within pre- and post-resettlement contexts.

  14. An anthropology of learning on nested frictions in cultural ecologies

    CERN Document Server

    Hasse, Cathrine

    2015-01-01

    This book has one explicit purpose: to present a new theory of cultural learning in organisations which combines practice-based learning with cultural models - a cognitive anthropological schema theory of taken-for-granted connections - tied to the everyday meaningful use of artefacts. The understanding of culture as emerging in a process of learning open up for new understandings, which is useful for researchers, practitioners and students interested in dynamic studies of culture and cultural studies of organisations. The new approach goes beyond culture as a static, essentialist entity and open for our possibility to learn in organisations across national cultures, across ethnicity and across the apparently insurmountable local educational differences which makes it difficult for people to communicate working together in an increasingly globalized world. The empirical examples are mainly drawn from organisations of education and science which are melting-pots of cultural encounters.

    Multiple actors are typically involved in forest management, namely communities, managers and researchers. In such cases, suboptimal management outcomes may, in addition to other factors, be symptomatic of a divergence in perspectives among these actors driven by fundamental differences in ecological knowledge. We examine the degree of congruence between the understandings of actors surrounding key issues of management concern in three case studies from tropical, subtropical and boreal forests. We identify commonly encountered points of divergence in ecological knowledge relating to key management processes and issues. We use these to formulate seven hypotheses about differences in the bodies of knowledge that frequently underlie communication and learning failures in forest management contexts where multiple actors are involved and outcomes are judged to be suboptimal. Finally, we present a set of propositions to acknowledge and narrow these differences. A more complete recognition of the full triangulation between all actors involved, and of the influence that fundamental differences in ecological knowledge can exert, may help lead to a more fruitful integration between local knowledge and practice, manager knowledge and practice, and contemporary science in forest management.

    The ability to navigate is a hallmark of living systems, from single cells to higher animals. Searching for targets, such as food or mates in particular, is one of the fundamental navigational tasks many organisms must execute to survive and reproduce. Here, we argue that a recent surge of studies of the proximate mechanisms that underlie search behavior offers a new opportunity to integrate the biophysics and neuroscience of sensory systems with ecological and evolutionary processes, closing a feedback loop that promises exciting new avenues of scientific exploration at the frontier of systems biology.

    Science.gov (United States)

    Schuwirth, Nele; Reichert, Peter

    2013-02-01

    For the first time, we combine concepts of theoretical food web modeling, the metabolic theory of ecology, and ecological stoichiometry with the use of functional trait databases to predict the coexistence of invertebrate taxa in streams. We developed a mechanistic model that describes growth, death, and respiration of different taxa dependent on various environmental influence factors to estimate survival or extinction. Parameter and input uncertainty is propagated to model results. Such a model is needed to test our current quantitative understanding of ecosystem structure and function and to predict effects of anthropogenic impacts and restoration efforts. The model was tested using macroinvertebrate monitoring data from a catchment of the Swiss Plateau. Even without fitting model parameters, the model is able to represent key patterns of the coexistence structure of invertebrates at sites varying in external conditions (litter input, shading, water quality). This confirms the suitability of the model concept. More comprehensive testing and resulting model adaptations will further increase the predictive accuracy of the model.

    2011-01-01

    Despite the rapid growth of the elderly African American population in the U.S., elder abuse and neglect in African American families continue to be underdeveloped areas of study. This article presents an ecological and culturally informed framework for the study of elder abuse in African American populations. The model was developed based on Bronfenbrenner's Human Ecological Theory. The model identifies risk factors associated with different systems that have an influence on the lives of African American families. Cultural protective factors also are identified in the model. The model is intended to provide an understanding of elder abuse and neglect in African American families by considering the influence of contextual factors such as the legacy of slavery, social exclusion, and structural segregation and racism. Specific suggestions for practice are proposed according to cultural strengths of African American communities as well as the ecological premises of the model.

    Stephanie J. Rotarangi

    2014-03-01

    Full Text Available How is cultural resilience achieved in the face of significant social and ecological change? Is resilience compatible with changed structures, functions, and feedbacks as long as identity is maintained? The concept of cultural resilience has been less explored than its older siblings ecological resilience, social resilience, and social-ecological resilience. We seek to redress the balance, drawing from resilience thinking to examine how a New Zealand Māori tribal group of landowners retained strong cultural identity and connectedness to their land despite enduring significant changes in land use, economy, tenure, and governance. The landowners negotiated radical transformations in the ecology and land use of their home lands on terms that supported matters of cultural importance. The key resilience concepts of adaptation and transformation were helpful in analyzing the trajectory of change, but fell short of representing the elements of stability that supported the cultural resilience of the landowners. The concept of resilience pivots was designed to address this conceptual gap, and to offer another heuristic to resilience thinking by focusing on stability rather than change. Resilience pivots are those elements of a resilient system that remain stable despite adaptation or even transformation of other elements of that system, and in doing so support the maintenance of the system's distinctive identity.

  5. Learning to bridge the gap between adaptive management and organisational culture

    Directory of Open Access Journals (Sweden)

    Richard J. Stirzaker

    2011-05-01

    Full Text Available Adaptive management is the problem-solving approach of choice proposed for complex and multistakeholder environments, which are, at best, only partly predictable. We discuss the implications of this approach as applicable to scientists, who have to overcome certain entrained behaviour patterns in order to participate effectively in an adaptive management process. The challenge does not end there. Scientists and managers soon discover that an adaptive management approach does not only challenge conventional scientific and management behaviour but also clashes with contemporary organisational culture. We explore the shortcomings and requirements of organisations with regard to enabling adaptive management. Our overall conclusion relates to whether organisations are learning-centred or not. Do we continue to filter out unfamiliar information which does not fit our world view and avoid situations where we might fail, or do we use new and challenging situations to reframe the question and prepare ourselves for continued learning? Conservation implications: For an organisation to effectively embrace adaptive management, its mangers and scientists may first have to adapt their own beliefs regarding their respective roles. Instead of seeking certainty for guiding decisions, managers and scientists should acknowledge a degree of uncertainty inherent to complex social and ecological systems and seek to learn from the patterns emerging from every decision and action. The required organisational culture is one of ongoing and purposeful learning with all relevant stakeholders. Such a learning culture is often talked about but rarely practised in the organisational environment.

    Among the different factors associated to change in traditional ecological knowledge, the study of the relations between cultural change and traditional ecological knowledge has received scan and inadequate scholarly attention. Using data from indigenous peoples of an Amazonian society facing increasing exposure to the mainstream Bolivian society, we analyzed the relation between traditional ecological knowledge, proxied with individual plant use knowledge (n=484), and cultural change, proxied with individual- and village-level (n=47) measures of attachment to traditional beliefs and values. We found that both the individual level of detachment to traditional values and the village level of agreement in detachment to traditional values were associated with individual levels of plant use knowledge, irrespective of other proxy measures for cultural change. Because both the individual- and the village-level variables bear statistically significant associations with plant use knowledge, our results suggest that both the individual- and the supra-individual level processes of cultural change are related to the erosion of plant use knowledge. Results from our work highlight the importance of analyzing processes that happen at intermediary social units -the village in our case study- to explain changes in traditional ecological knowledge.

    The purpose of this 2-year study was to investigate Malawian teacher educators' perspectives and dispositions toward teaching about ecological sustainability issues in Malawi, a developing country in sub-Sahara Africa. This study was embedded in a larger theoretical framework of investigating earth systems science through the understanding of nature-knowledge-culture systems from local, place-based perspectives. Specifically, we were interested in learning more about eco-justice issues that are related to environmental degradation in Malawi and the potential role of inquiry-oriented pedagogies in addressing these issues. In a science methods course, the African educators' views on deforestation and teaching about ecological sustainability were explored within the context of the local environment and culture. Teachers participated in inquiry pedagogies designed to promote the sharing of perspectives related to the connections between culture and ecological degradation. Strategies encouraging dialogue and reflection included role-playing, class discussions, curriculum development activities, teaching experiences with children, and field trips to a nature preserve. Data were analyzed from postcolonial and critical pedagogy of place theoretical perspectives to better understand the hybridization of viewpoints influenced by both Western and indigenous science and the political hegemonies that impact sustainable living in Malawi. Findings suggested that the colonial legacy of Malawi continues to impact the ecological sustainability issue of deforestation. Inquiry-oriented pedagogies and connections to indigenous science were embraced by the Malawian educators as a means to involve children in investigation, decision making, and ownership of critical environmental issues.

    From ancient times in the world, original ecological culture was prior to the common culture in a region or a country or even the world. Original ecological national culture, the original culture of a community, belongs to its nation who have created and kept the culture abreast of the times. Such culture has its original signification, retains the basic state of its birth and owns relative stability in history with nature as its main feature. The concept of original ecology national culture is actually in conformity with its essence. Its research is conducive to the construction of ecological civilizations, to the protection of cultural diversity and local knowledge. Its theoretical construction is critical in the modern times for the inheritance of excellent national traditional culture and for the construction of socialist culture.%亘古以来,在世界范围内,先有原生态民族文化,后有地区的国家的甚至全世界共同的文化。原生态民族文化是拥有该文化的民族创造的与时俱进而又能基本上保持原始状态的传统文化,是人们共同体传承到当今时代的原创性文化。它具备原创时的本真意义,保留着诞生时的基本状态,在历史长河中具有相对的稳定性。"本真"是原生态民族文化的显著特征。我们今天提出"原生态民族文化"的概念,名符其实。对它进行研究,有利于生态文明的建设,有利于保护文化的多样性和地方性知识。"原生态民族文化"的理论构建是传承民族优秀传统文化、建设社会主义文化的时代需要。

  14. How National Culture and Parental Style Affect the Process of Adolescents’ Ecological Resocialization

    2015-06-01

    Full Text Available The role of adolescents as influencers on their families’ environmental behavior is potentially a catalyst for change towards increasing eco-friendly actions. In this paper, the authors report on a cross-cultural study of ecological resocialization in France and India. Using in-depth dyadic interviews, they investigated parental styles, cultural attributes and extent of adolescents’ influence over parental eco-behavior. The study reveals that ecological resocialization across countries differs substantially, according to a combination of national cultural values, parental style and influence strategy. French teens exhibit a greater impact than Indian teens on their parents’ eco-behavior and use bilateral influence strategies. In India, not all mothers engage in ecological resocialization, but those who do are susceptible to unilateral strategies. The role of environmental knowledge, and the context and effectiveness of each kind of strategy is discussed. The findings have implications for how public policy officials and agencies can encourage adolescents as key resocialization agents to influence their parents’ pro-environmental consumption by using the most adapted influence strategy across cultures.

  15. Cultural Foundations for Ecological Restoration on the White Mountain Apache Reservation

    Full Text Available Myths, metaphors, and social norms that facilitate collective action and understanding of restoration dynamics serve as foundations for ecological restoration. The experience of the White Mountain Apache Tribe demonstrates how such cultural foundations can permeate and motivate ecological restoration efforts. Through interviews with tribal cultural advisors and restoration practitioners, we examined how various traditions inform their understanding of restoration processes. Creation stories reveal the time-honored importance and functions of water bodies within the landscape, while place names yield insights into their historical and present conditions. Traditional healing principles and agricultural traditions help guide modern restoration techniques. A metaphor of stability illustrates how restoration practitioners see links among ecological, social, and personal dimensions of health. These views inspire reciprocal relationships focused on caretaking of sites, learning from elders, and passing knowledge on to youths. Woven together, these cultural traditions uphold a system of adaptive management that has withstood the imposition of non-indigenous management schemes in the 20th century, and now provides hope for restoring health and productivity of ecosystems through individual and collective efforts. Although these traditions are adapted to the particular ecosystems of the Tribe, they demonstrate the value of understanding and promoting the diverse cultural foundations of restoration.

    2007-11-01

    Full Text Available Heritage protection in China has long been considered as the responsibility of the government. However, over the last 20 years, a number of heritage projects, mainly in ethnic minority regions, have attempted to engage with local communities. These seem to be an attractive alternative to top-down approaches. This paper explores the implications of a bottom-up approach for Chinese ethnic minority heritage management through an examination of the Ethnic Cultural and Ecological Village project in Xianrendong in Yunnan province. It is a result of my fascination with the project’s concept and my desire to understand its key characteristics, application and potential for future development in China. After a discussion of cultural performance, modernisation and inside/outside encounters, I conclude by suggesting that well-planned and well-informed community participation, with realistic control, contributes to reconciling tourism and cultural heritage conservation.

  18. Turn left for Murmansk: ‘Fourth World’ transculturalism and its cultural ecological framing

    Directory of Open Access Journals (Sweden)

    Patrick Dillon

    2014-04-01

    Full Text Available In this paper we review briefly histories and ideologies underlying multiculturalism in Nordic countries, highlighting tensions between integrationist and inclusive approaches. We propose a cultural ecological framework through which we discuss the possibility of a transculturalism based on Fourth World engagement with the environment. Cultural ecology is about the reciprocal interactions and transactions between people and their environments. The Fourth World is a circum-global, pan-arctic region which includes the northern parts of some Nordic countries. We argue that whether or not there is a distinctively Nordic version of multiculturalism, Nordic countries have access to Fourth World ways of engaging with the environment which transcend notions of inter- and multiculturalism and the ideological tensions associated with them.

    This chapter offers insights from the environmental management paradigm of 'social-ecological systems' and related bodies of theory on people-environment relationships to assist the evolution of the One Health interdisciplinary endeavour of health promotion across human-animal ecosystem relationships. It also seeks to expand thinking about the social and cultural dimensions that are likely to prove important in the development of thinking and practice in the One Health field. It advocates consideration of cultural and economic relationships affecting people's interactions with domesticated and wild animal species and ecosystems, and exploration of the cognitive and behavioural aspects of these interactions.

  1. Cultural or Ecological Sustainability? The Effect of Cultural Change on Sabal Palm Management Among the Lowland Maya of Mexico

    Andrea Martínez-Ballesté

    2006-12-01

    Full Text Available Sabal palm has been used for thatching the traditional Maya house for over 3000 yr. The great importance of this resource has promoted its management within home gardens. Although traditionally managed populations in home gardens are capable of ecological long-term persistence, the impact of cultural change on sustainable resource management is poorly understood. By means of interviews in 108 households, we obtained information about Sabal management practices, leaf demand, and sociocultural data. Density and size structure of the palm populations in the respective home gardens were also measured. By means of principal components analysis, the sociocultural data were summarized into a cultural change index, which was then statistically related to palm density, size structure, leaf demand, and management practices. Leaf demand along the cultural change gradient was estimated. Sabal populations were affected by the cultural change index. Palm density and the proportion of harvestable individuals were higher in the more traditional households. The number of management practices decreased, and the probability of felling adult palms increased with cultural change. As a result, the percentage of the total leaf demand satisfied by home garden production diminished from 118.2-69.4% as cultural change increased. Traditional practices seem oriented to increasing the palm availability. Seed sowing and the protection of seedlings and adults affect the life stages with the largest impact on the population growth rate, as measured through sensitivity analysis. This means that abandoning traditional practices and felling adults more frequently should reduce rapidly, which is consistent with the low palm density observed in less traditional households. The application of demographic models to Sabal tells us that traditional management warrants the persistence of the resource as long as the current conditions remain unchanged. In contrast, our data show that

    2007-01-01

    To examine the effects of risk on infant development within cultural contexts, 141 dual-earner Israeli and Palestinian couples and their first-born child were observed at 5 months and again at 34 months. Eight ecological determinants were examined as potential risk factors, including the infant's observed and parent-reported difficult temperament; the mother's depressive symptoms, work-family interference, and experience of childbirth; the parents' marital satisfaction and social support; and observed maternal and paternal sensitivity. Symbolic play and behavior problems were assessed at 34 months. Culture-specific effects of risk and protective factors were found. Parent sensitivity facilitated symbolic competence to a greater extent in the Israeli group. Culture moderated the effects of maternal depression and family social support on toddlers' behavior problems. Maternal depressive symptoms had a negative impact on the behavior adaptation of Israeli children and social support buffered against behavior problems in the Arab group. Implications for research on risk and resilience and the role of culture in moderating the effects of ecological risk are discussed.

    Beidong minorities living together in Qingshui River valley are deeply influenced by Jing and Chu culture. Their ethnic and traditional culture was developed in the process of collision with foreign culture. In the several great social transformations,their cultural ecology was not imbalanced,but evolved and developed. Through the study on local knowledge of cultural ecology including agricultural production,ancestral hall and local- style dwelling house,full- scale drama and Yang Drama,genealogical system,marriage customs,religious belief,sacrificial rites and funeral rites,it is expected to reveal reasons and rules of transition of Beidong ethnic culture,favorable for correctly understanding cultural connotation and promote cultural and tourism development in ethnic minority areas.

  5. The Relationship between Traditional Ecological Knowledge, Evolving Cultures, and Wilderness Protection in the Circumpolar North

    Directory of Open Access Journals (Sweden)

    Lilian Alessa

    2003-12-01

    Full Text Available There are many unique issues associated with natural resource management in the far north as a result of legislative direction, historic settlement and occupation patterns, northern cultural traditions, ecotourism, economic depression, pressures for energy development, and globalization and modernization effects. Wilderness designation in Canada, the USA, and Finland is aimed at preserving and restoring many human and ecological values, as are the long-established, strictly enforced, nature reserves in Russia. In Alaska and Finland, and in some provinces of Canada, there is a variety of values associated with protecting relatively intact relationships between indigenous people and relatively pristine, vast ecosystems. These values are often described as “traditional means of livelihood,” “traditional means of access,” “traditional relationships with nature,” or “traditional lifestyles.” Traditional ecological knowledge (TEK forms part of these relationships and has been acknowledged as a contributor to understanding the effects of management decisions and human-use impacts on long-term ecological composition, structure, and function. Wilderness protection can help maintain opportunities to continue traditional relationships with nature. As cultures continue to evolve in customs, attitudes, knowledge, and technological uses, values associated with both TEK and relationships with relatively pristine ecosystems will also evolve. Understanding these relationships and how to consider them in wilderness protection and restoration decision making is potentially one of the most contentious, widespread natural resource management issues in the circumpolar north.

  11. Woodland restoration in Scotland: ecology, history, culture, economics, politics and change.

    Science.gov (United States)

    Hobbs, Richard

    2009-07-01

    In the latter half of the 20th century, native pine woodlands in Scotland were restricted to small remnant areas within which there was little regeneration. These woodlands are important from a conservation perspective and are habitat for numerous species of conservation concern. Recent developments have seen a large increase in interest in woodland restoration and a dramatic increase in regeneration and woodland spread. The proximate factor enabling this regeneration is a reduction in grazing pressure from sheep and, particularly, deer. However, this has only been possible as a result of a complex interplay between ecological, political and socio-economic factors. We are currently seeing the decline of land management practices instituted 150-200 years ago, changes in land ownership patterns, cultural revival, and changes in societal perceptions of the Scottish landscape. These all feed into the current move to return large areas of the Scottish Highlands to tree cover. I emphasize the need to consider restoration in a multidisciplinary framework which accounts not just for the ecology involved but also the historical and cultural context.

  12. Cross-Cultural Differences and Similarities in Proneness to Shame: An Adaptationist and Ecological Approach

    Directory of Open Access Journals (Sweden)

    Daniel Sznycer

    2012-04-01

    Full Text Available People vary in how easily they feel ashamed, that is, in their shame proneness. According to the information threat theory of shame, variation in shame proneness should, in part, be regulated by features of a person's social ecology. On this view, shame is an emotion program that evolved to mitigate the likelihood or costs of reputation-damaging information spreading to others. In social environments where there are fewer possibilities to form new relationships (i.e., low relational mobility, there are higher costs to damaging or losing existing ones. Therefore, shame proneness toward current relationship partners should increase as perceived relational mobility decreases. In contrast, individuals with whom one has little or no relationship history are easy to replace, and so shame-proneness towards them should not be modulated by relational mobility. We tested these predictions cross-culturally by measuring relational mobility and shame proneness towards friends and strangers in Japan, the United States, and the United Kingdom. Japanese subjects were more shame-prone than their British and American counterparts. Critically, lower relational mobility was associated with greater shame proneness towards friends (but not strangers, and this relationship partially mediated the cultural differences in shame proneness. Shame proneness appears tailored to respond to relevant features of one's social ecology.

  13. Nothingness and the human umwelt: a cultural-ecological approach to meaning.

    Science.gov (United States)

    Bang, Jytte

    2009-12-01

    In the paper I argue that the great impact of empiricism on psychology and the enclosed dualist agenda traps psychological phenomena into subjectivism. By discussing the phenomena of nothingness in biological and cultural life it is argued that meaning must be considered as a phenomenon that represents both a fit and a misfit of the individual with the environment. By stressing the overall presence of nothingness phenomena it is argued how the reduced ontology of empiricism--and its blindness to relations and transformations out of which meaning grows--should be overcome. In human cultural life, transformations are constitutive and ongoing changes are being produced to make sure that continuity as well as discontinuity will happen. The analysis of especially one case--the removal of an Amish school after a shooting episode--serves to prove how meaning grows out of cultural processes as people produce their own conditions of life. From a cultural-ecological point of view, analyzing meaning at the level of individual phenomenology, hence, means analyzing the 'total psychological situation' (legacy of Kurt Lewin). This may for instance include analyzing how people live, what they consider important and worth preserving, what must be changed, what are their core values and how do institutional arrangements contribute to keeping up that which is valued or to changing that which is not, etc. Meaning may be viewed the lived-out experience-the domain of self-generativity in human life.

    2015-12-01

    Postmortem microorganisms are increasingly recognized for their potential to serve as physical evidence. Yet, we still understand little about the ecology of postmortem microbes, particularly those associated with the skin and larval masses. We conducted an experiment to characterize microbiological and chemical properties of decomposing swine (Sus scrofa domesticus) carcasses on the island of Oahu, Hawaii, USA, during June 2013. Bacteria were collected from the head, limb, and larval mass during the initial 145h of decomposition. We also measured the pH, temperature, and oxidation-reduction potential of larval masses in situ. Bacteria were cultured aerobically on Standard Nutrient Agar at 22°C and identified using protein or genetic signals. Carcass decomposition followed a typical sigmoidal pattern and associated bacterial communities differed by sampling location and time since death, although all communities were dominated by phyla Actinobacteria, Firmicutes, and Proteobacteria. Larval masses were reducing environments (~-200mV) of neutral pH (6.5-7.5) and high temperature (35°C-40°C). We recommend that culturable postmortem and larval mass microbiology and chemistry be investigated in more detail, as it has potential to complement culture-independent studies and serve as a rapid estimate of PMI.

  19. Algae for controlled ecological life support system diet characterization of cyanobacteria 'spirulina' in batch cultures

    Science.gov (United States)

    Tadros, M. G.

    1990-01-01

    Spirulina sp. is a bioregenerative photosynthetic and edible alga for space craft crews in a Closed Ecological Life Support System (CLESS). It was characterized for growth rate and biomass yield in batch cultures, under various environmental conditions. The cell characteristics were identified for one strain of Spirulina: S. maxima. Fast growth rate and high yield were obtained. The partitioning of the assimulatory products (proteins, carbohydrates, lipids) were manipulated by varying the environmental conditions. Experiments with Spirulina demonstrated that under stress conditions carbohydrate increased at the expense of protein. In other experiments, where the growth media were sufficient in nutrients and incubated under optimum growth conditions, the total proteins were increased up to almost 70 percent of the organic weight. In other words, the nutritional quality of the alga could be manipulated by growth conditions. These results support the feasibility of considering Spirulina as a subsystem in CELSS because of the ease with which its nutrient content can be manipulated.

  20. The cultural and ecological impacts of aboriginal tourism: a case study on Taiwan's Tao tribe.

    Science.gov (United States)

    Liu, Tzu-Ming; Lu, Dau-Jye

    2014-01-01

    We show that tourism activities severely impact the ecology of Orchid Island, its natural resources, and the culture of the Tao tribe. For example, highway widening, in response to the increased traffic volumes caused by tourism, required many Pandanus trees to be cut and removed, which has placed the coconut crabs in danger of extinction. To promote eco-tourism, observation trips to observe Elegant Scops owls and Birdwing butterflies have taken place, which has affected the breeding of these two protected species. The Elegant Scops owls- and Birdwing butterflies-related tourism activities also break the "evil spirits" taboo of the Tao people and have caused the disappearance of the specifications for using traditional natural resources, causing natural ecosystems to face the threat of excessive use. In addition to promoting and advocating aboriginal tourism of the Tao people on Orchid Island, the Taiwanese government should help the Tao people to develop a management model that combines traditional regulations and tourism activities.

  1. Post-cultural stand dynamics in an abandoned chestnut coppice at its ecological border

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Until the be­ginning of the last century, chestnut has played an important role as staple food and primary wood source. In many cases it was cultivated at the border of its ecological limits where it was planted by man in place of the original and more site-adapted tree species. However, with the abandonment of the rural activities, ma­nagement of chestnut forests was progressively left starting from more marginal areas, usually occupied by coppice stands. After the interruption of the traditional coppice management system (usual rotation periods of 10-25 years, natural intra- and interspecific competition dynamics have become the driving force of the stand evolution. This may lead to dramatic changes in both structure and species composition of the stands. The aim of this study is to analyse the post-cultural evolution of an abandoned chestnut coppice in the Pesio Valley (Piedmont, Italy in order to highlight the competition among different "basic silvi­cultural components" of the forest using a dendroecological approach. The "basic silvicultural components" are intended as the elements defined as groups of trees of the stand that have similar features such as silvi­culturally relevant attributes: species (chestnut, beech, fir, origin (seed, sprout and cultural age and function (standard/reserve, maiden, shoot, regeneration, dead tree. The mean growth curves of the compo­nents show the different fitness of each category. From a general point of view, the beech and fir components show a better competitive potential in comparison with chestnut. Among chestnut components, maidens from seeds reveal a better growth trend compared to coppice shoots and standards.

    2015-03-01

    This paper approaches mindfulness, an awareness of internal and external realities, as a culturally-shaped habit of mind. Findings of a cross-cultural study and popular sayings that reflect America's cultural orientation to consumption and competition are contrasted with findings from Hawaiian language newspapers, traditional cultural practices, and Hawaiian sayings that indicate an orientation to ecological mindfulness that increased the resilience of fragile social ecosystems. Marginalization of indigenous culture, language, and knowledge and cultural differences between teachers and indigenous students are proposed as a contributing factor to lower science performance of Native Hawaiian students in mainstream schools. Two professional development projects designed to reduce conflicts between culture and science instruction are presented. Findings from these projects suggest alignment of science inquiry with indigenous cultural knowledge and practices oriented to sustainability supports the development of teachers' ecological mindfulness as indicated by increased awareness of, interest in, and incorporation of place and culture-based based resources into their instruction. Teacher feedback indicates that mapping technologies that enable teachers to visualize and integrate indigenous place-based Hawaiian knowledge with science inquiry are promising instructional strategies.

    Transracial adoptees represent a specific group of immigrants who experience unique immigration processes that bring them face-to-face with two cultural backgrounds: that of their heritage culture on one hand and that of their national culture on the other hand. However, there is a scarcity of studies focused on the way these processes unfold within adoptive families. This study was aimed at exploring how transracial adoptees cope with the construction of their ethnic identity. Administering a self-report questionnaire to 127 transracial adoptees and their mothers, for a total of 254 participants, we first investigated the association between mothers' cultural socialisation (enculturation and preparation for bias strategies) and adoptees' ethnic identity (i.e. ethnic identity exploration and ethnic identity affirmation dimensions). We then investigated whether ethnic identity affects self-esteem by testing the hypothesis that national identity moderates the relationship between ethnic identity and self-esteem. Results revealed that mothers' enculturation (but not their preparation for bias) supported adoptees' ethnic identity exploration, which in turn was positively associated with ethnic identity affirmation. Moreover, we confirmed the moderation effect: ethnic identity affirmation enhanced the level of self-esteem, but only for those adoptees who perceived a higher degree of national identity affirmation.

    Brescia, an industrial city in Northern Italy, is now experiencing a crucial change in its traditional structure. In recent years in fact it has been elected as living and working seat by many foreigners and it is now one of the cities with the greatest percentage of migrants in the Country. This is an important challenge for the city and an opportunity to merge, compare and integrate different cultures to build its future. In this context some students of different Courses (engineering and medicine), belonging both to the Arabian and local community, met together and with researchers in the study team 'Al-B¯i r¯u n¯i , for culture, science and society'. The team aims at organising cultural events in which, starting from the figure of the Persian scientist Ab¯u Raih. ¯a n Al-B¯i r¯u n¯i (about 973, 1051), the contribution of the Arabian and Islamic culture to the development of the European one in the middle ages is investigated. Moving from the initial idea of the study team Al-B¯i r¯u n¯i and from the suggestions of the World Soil Day 2014 and of the International Year of Soils 2015, we built a documentary exhibition entitled 'Irrigation techniques in water scarcity conditions'. The exhibition, which stresses the importance of the irrigation techniques for the soil conservation, is focused on the idea of disseminating two main concepts, i.e. (1) the technological continuity of some water supply systems in countries, around the Mediterranean Sea, affected by similar conditions of water availability, and (2) the possibility of building environments where, due to severe or extreme climatic conditions, the sustainability is reached when the man lives in equilibrium with the nature. The exhibition, which is written in Italian and will move around in the city during all 2015, consists of about twenty posters organized into three main chapters, corresponding to three main classes of water supply systems which are common in most of the countries surrounding

  11. Introduction to a special section: Ecology, culture, and management of Burbot

    Stapanian, Martin A.; Madenjian, Charles P.

    2013-01-01

    The Burbot Lota lota is the only truly freshwater member of the cod family (Gadidae) and one of only two species of freshwater fish that have a circumpolar range (McPhail and Lindsey 1970; McPhail and Paragamian 2000). Two subspecies of Lota lota have been documented: Lota lota maculosa, which is found exclusively in North America from south of Great Slave Lake in Canada to the southern limit of its range; and Lota lota lota, which is found over the remainder of the species’ Nearctic range and its entire Eurasian range (Hubbs and Schultz 1941; Van Houdt et al. 2003). However, many recent authorities (e.g., Scott and Crossman 1973) do not designate subspecies. Burbot occupy the widest range of depths of all fishes found in the Laurentian Great Lakes basin (i.e., from small streams to at least 300 m in Lake Superior; Boyer et al. 1989). Worldwide, many Burbot populations are threatened or endangered or have been extirpated (reviewed by Stapanian et al. 2010). Due in part to its unpopularity as a sport and commercial fish in much of its range, the species is often ignored in fish management and conservation programs (McPhail and Paragamian 2000; Stapanian et al. 2008, 2010). Even basic information on Burbot ecology, particularly its early life history and spawning habitats and sites, is lacking. This lack of information is particularly troubling because Burbot are an indicator of the health of coldwater systems (Stapanian et al. 2010). Efforts to rehabilitate or restore imperiled populations include culturing early life stages. Burbot larvae are difficult to culture for a variety of reasons, including their delicate body structure, small size at hatch, and live-feed requirement for at least 5 weeks following alimentary tract development.

    Full Text Available Ibsen-In-Translation aims at translating Ibsen’s work simultaneously into the languages of: Classic Arabic, Chinese, Egyptian, English, Hindi, Japanese, Russian and Spanish. During the translation of En Folkefiende the group met twice to discuss problems and help eachother’s understanding of the play. This article aims at pointing out some of the common translation-problems the eight translators encountered, and to mention specific problems I encountered in the process of translating the play into Japanese. During our two meetings, I saw that some problems were language-specific, and that some were common to more of us. We also discovered that some words and expressions are so rooted in the Norwegian culture and that a literal translation of such words and expressions create different associations in the target language. Among the problems we had in common, there seemed to be two main categories. 1: Concepts related to Christian values, and 2: Concepts related to the Norwegian societal organization of the time. Christian values-related problems consisted of translating swearwords, translating the concepts and the associations related to the words ”temperance”, ”atheism” and ”openmindedness”. As for the problems relating to societal organization and political ideology in Norway of the time, concepts relating to the term ”borger” was a challenge for many of us. As for me specifically, I also had the added challenge of fitting the relatively democratic language of Ibsen into the Japanese hierarchical language system.

    2002-07-01

    The cultural and ecological values of Pacific lamprey (Lampetra tridentata) have not been understood by Euro-Americans and thus their great decline has almost gone unnoticed except by Native Americans, who elevated the issue and initiated research to restore its populations, at least in the Columbia Basin. They regard Pacific lamprey as a highly valued resource and as a result ksuyas (lamprey) has become one of their cultural icons. Ksuyas are harvested to this day as a subsistence food by various tribes along the Pacific coast and are highly regarded for their cultural value. Interestingly, our review suggests that the Pacific lamprey plays an important role in the food web, may have acted as a buffer for salmon from predators, and may have been an important source of marine nutrients to oligotrophic watersheds. This is very different from the Euro-American perception that lampreys are pests. We suggest that cultural biases affected management policies.

    The objectives of this study were to determine the influence of a Saccharomyces cerevisiae fermentation product on innate immunity and intestinal microbial ecology after weaning and transport stress. In a randomized complete block design, before weaning and in a split-plot analysis of a 2 × 2 factorial arrangement of yeast culture (YY) and transport (TT) after weaning, 3-d-old pigs (n = 108) were randomly assigned within litter (block) to either a control (NY, milk only) or yeast culture diet (YY; delivered in milk to provide 0.1 g of yeast culture product/kg of BW) from d 4 to 21. At weaning (d 21), randomly, one-half of the NY and YY pigs were assigned to a 6-h transport (NY-TT and YY-TT) before being moved to nursery housing, and the other one-half were moved directly to nursery housing (NY-NT and YY-NT, where NT is no transport). The yeast treatment was a 0.2% S. cerevisiae fermentation product and the control treatment was a 0.2% grain blank in feed for 2 wk. On d 1 before transport and on d 1, 4, 7, and 14 after transport, blood was collected for leukocyte assays, and mesenteric lymph node, jejunal, and ileal tissue, and jejunal, ileal, and cecal contents were collected for Toll-like receptor expression (TLR); enumeration of Escherichia coli, total coliforms, and lactobacilli; detection of Salmonella; and microbial analysis. After weaning, a yeast × transport interaction for ADG was seen (P = 0.05). Transport affected (P = 0.09) ADFI after weaning. Yeast treatment decreased hematocrit (P = 0.04). A yeast × transport interaction was found for counts of white blood cells (P = 0.01) and neutrophils (P = 0.02) and for the neutrophil-to-lymphocyte ratio (P = 0.02). Monocyte counts revealed a transport (P = 0.01) effect. Interactions of yeast × transport (P = 0.001) and yeast × transport × day (P = 0.09) for TLR2 and yeast × transport (P = 0.08) for TLR4 expression in the mesenteric lymph node were detected.

    Full Text Available The article covers the formation of ecological culture of military high school cadets in the process of the museum’s research activities. The author defines the main mechanism of ecological culture formation, being characteristic of military high school cadets, and believes that the development of the cadets’ ecological culture, while they are engaged in the research process, will be effective, provided an innovative research context has been set up within the educational activities scope of the high school’s museum. For this purpose, the author suggests both considering the formation of ecological culture of military high school cadets in the process of the museum’s research activities and revealing certain links between the following components: socio-cultural environment and the museum’s one, the cadets’ research activities and the setting up of the ecological display at the museum, which comprises the contents of the museum teaching science. The author considers this model to be efficient for the purposes of the formation of the cadets’ ecological culture within the museum educational environment, as it has been proved efficient at a civil high school.

    In the early development of maritime anthropology ,the paradigm of cultural ecology has dominated the research of maritime anthropology ,and still been a very important influence until today . Maritime anthropology from the perspective of cultural ecology holds the view that the marine ecosystem is responsible for producing special marine socio-culture .In other words ,the constraints and uncertainties of marine environment lead to people's particular approaches and adaptation strategy to life ,w hich result in a different type of social culture unlike that in the land society .But with the self-development of the disci-pline ,scholars have realized the defects of the paradigm of cultural ecology from the 1980s ,and gradually turned to other perspectives and themes in the research of maritime anthropology .%在海洋人类学发展的早期,文化生态范式一直主导着海洋人类学的研究,并且直到今天仍有很重要的影响。海洋人类学的文化生态视角认为,海洋生态系统是产生特殊的海洋社会文化的原因,换而言之,也就是说海洋环境的限制和不确定性会导致人们对于生活特定的应对方式和适应策略,从而产生一个不同于陆地社会的社会文化类型。但是随着海洋人类学自身的发展,从20世纪80年代开始,学者们开始意识到文化生态范式的缺陷,并逐渐转向其他视角和主题的海洋人类学研究。

    Full Text Available Abstract Background The Peruvian Andean region is a main center of plant domestication of the world. There, several tuber species were domesticated and the area lodges one of the most important reservoirs of their varieties and wild relatives. It is also the setting of traditional cultures using and conserving them. However, crop genetic erosion has been reported in the region since several decades ago; therefore, understanding factors influencing both loss and maintenance of crop variation is relevant to design conservation policies. Previous researches have examined factors influencing agrobiodiversity conservation in the region but additional case studies are recognized to be still necessary for a deeper understanding of causes of genetic erosion and for policy design to prevent and remedy it. Our study focused on analyzing (1 variation in richness of traditional varieties of tubers cultivated among households, (2 changes in varieties richness occurred in four consecutive agricultural cycles, and (3 ecological, social, and cultural factors influencing loss and conservation of varieties. Methods Richness of farmer varieties of tuber species cultivated by 28 peasant households was monitored in communities of Cajamarca and Huánuco, Peru during four consecutive agricultural cycles (from 2001 to 2005. In-depth interviews were conducted with 12 of the households with higher reputation as conservationists, in order to document farmers' perception of tubers qualities in ecological, social, economic, technological and culinary aspects and how these influence their decisions of conservation priorities. Traditional varieties were identified according to their local names, which were then confronted among farmers and with scientific catalogues in order to identify synonyms. Based on the information documented, indexes of ecological and socio-cultural factors affecting agricultural practices were designed, and their linear correlations and multivariate

    Lobsters are prized by commercial and recreational fishermen worldwide, and their populations are therefore buffeted by fishery practices. But lobsters also remain integral members of their benthic communities where predator-prey relationships, competitive interactions, and host-pathogen dynamics push and pull at their population dynamics. Although lobsters have few reported pathogens and parasites relative to other decapod crustaceans, the rise of diseases with consequences for lobster fisheries and aquaculture has spotlighted the importance of disease for lobster biology, population dynamics and ecology. Researchers, managers, and fishers thus increasingly recognize the need to understand lobster pathogens and parasites so they can be managed proactively and their impacts minimized where possible. At the 2011 International Conference and Workshop on Lobster Biology and Management a special session on lobster diseases was convened and this special issue of Diseases of Aquatic Organisms highlights those proceedings with a suite of articles focused on diseases discussed during that session.

In this kind of construction activity ,ecocentrism which is based on the naturalistic explanation emphasizes the natural attributes of ecological culture, and is committed to forming one type of ecological culture construction framework beyond the traditional political and economical factors while the western Marxism which is based on the critique of political economics emphasizes the current capitalist system and the anti-ecology of globalization and claims to fundamentally solve the ecological environmental problems by establishing a basic socialist system. As these two theoretical interpretation paradigms and cultural construction frameworks have their respective advantages and disadvantage, it is necessary to learn from and draw on their advantages, and take China ’s national conditions and the socialist development path with Chinese characteristics into account when planning the ecological civilization construction.

  19. The diamondback terrapin: The biology, ecology, cultural history, and conservation status of an obligate estuarine turtle

    Science.gov (United States)

    Hart, K.M.; Lee, D.S.; ,

    2006-01-01

    Ranging from Cape Cod to nearly the Texas-Mexico border, the diamondback terrapin (Malaclemys terrapin) is the only species of North American turtle restricted to estuarine systems. Despite this extensive distribution, its zone of occurrence is very linear, and in places fragmented, resulting in a relatively small total area of occupancy. On a global scale, excluding marine species, few turtles even venture into brackish water on a regular basis, and only two Asian species approach the North American terrapin's dependency on estuarine habitats. Here we describe some of the biological and behavioral adaptations of terrapins that allow them to live in the rather harsh estuarine environment. In this chapter we review the natural and cultural history of this turtle, discuss conservation issues, and provide information on the types of research needed to make sound management decisions for terrapin populations in peril.

    Full Text Available The following are a few loose notes about a tough subject: the relationship between ethics, storytelling and the legal-cum-social framework that makes human creativity thrive or decay. Rather than a tight argument, what I propose here is a few, unoriginal hints, in the hope that they may help others to pursue a fuller answer to the question, On what depends the preservation of transmission of a culture? Using some thoughts by A. MacIntyre and some examples taken from the history of Icelandic literature, I emphasize the role of alternative ways of understanding intellectual property, as well as some contemporary experiments in mythopoiesis, such as the one by the Italian collective of writers-activists known as Wu Ming.

    2016-02-01

    Full Text Available Abstract Myocardial bridging is rare. Myocardial bridges are most commonly localized in the middle segment of the left anterior descending coronary artery. The anatomic features of the bridges vary significantly. Alterations of the endothelial morphology and the vasoactive agents impact on the progression of atherosclerosis of myocardial bridging. Patients may present with chest pain, myocardial infarction, arrhythmia and even sudden death. Patients who respond poorly to the medical treatment with β-blockers warrant a surgical intervention. Myotomy is a preferred surgical procedure for the symptomatic patients. Coronary stent deployment has been in limited use due to the unsatisfactory long-term results.

    2016-03-01

    To meet specific requirements of developing tissues urgently needed in tissue engineering, biomaterial research and drug toxicity testing, a versatile perfusion culture system was developed. First an individual biomaterial is selected and then mounted in a MINUSHEET(®) tissue carrier. After sterilization the assembly is transferred by fine forceps to a 24 well culture plate for seeding cells or mounting tissue on it. To support spatial (3D) development a carrier can be placed in various types of perfusion culture containers. In the basic version a constant flow of culture medium provides contained tissue with always fresh nutrition and respiratory gas. For example, epithelia can be transferred to a gradient container, where they are exposed to different fluids at the luminal and basal side. To observe development of tissue under the microscope, in a different type of container a transparent lid and base are integrated. Finally, stem/progenitor cells are incubated in a container filled by an artificial interstitium to support spatial development. In the past years the described system was applied in numerous own and external investigations. To present an actual overview of resulting experimental data, the present paper was written.

    This paper proposed a new concept of ecological security for protection by a comprehensive analysis of the contents and standards of world heritage sites. A frame concept model named "Pressure-State-Control" for early warning of ecological security at world heritage mixed sites was constructed and evaluation indicators of this frame were also selected. Wuyishan Scenery District was chosen for a case study, which has been severely disturbed by natural and artificial factors. Based on the frame model of "Pressure-State-Control" and by employing extension analysis, the matter-element model was established to assess the ecological security status of this cultural and natural world heritage mixed site. The results showed that the accuracy of ecological security early warning reached 84%. Early warning rank was I level (no alert status) in 1997 and 2009, but that in 2009 had a higher possibility to convert into II level. Likewise, the early-warning indices of sensitive ranks were different between 1997 and 2009. Population density, population growth rate, area index for tea garden, cultivated land owned per capita, level of drought, and investment for ecological and environmental construction were the main limiting factors to hinder the development of ecological security from 2009 to future. In general, the status of Wuyishan Scenery District ecological security was relatively good and considered as no alert level, while risk conditions also existed in terms of a few early-warning indicators. We still need to pay more attention to serious alert indicators and adopt effective prevention and control measures to maintain a good ecological security status of this heritage site.

    It has been a basic fact that sports originated from western civilization are popular all over the world. The attempt to simply remodel a traditional national sports activity into a sports event with the help of a western sports mode is very difficult to succeed. Oriental sports workers should find another way to exert advantages and overcome disadvantages, mine and improve traditional heath care culture in an in-depth way by applying scientific methods, dig out unique resources which had existed for thousand years long before western sports matured, and establish a way to ecological sports development by utilizing the lately developed advantage of oriental nations rising altogether. The field working method used by sports anthropology in China to explore/investigate primitive ecological sports activities is to, based on constructing scientific national sports, inspire the cultural awareness of activity groups themselves, pro-mote the social, organizational and institutional innovation of“oriental health care sports style”, so that traditional body movement culture in oriental civilization becomes fresh blood for future sports, even builds a system of its own in the sports leisure era, becomes mutually complementary together with western sports.%源于西方文明的体育运动风靡全球,已是基本事实。借助西方体育的模式把民族传统体育活动单纯改造为运动项目的尝试,很难成功。东方体育工作者应该另辟蹊径、扬长避短,运用科学方法深入挖掘与改进传统的养生保健文化,发掘西方体育成熟之前在东方已存续千年的独特资源,借助东方各民族携手崛起的后发优势,构建原生态体育发展之路。中国的体育人类学调查原生态体育活动的田野工作法,是为了以建设科学的民族体育志为基础,激发活动群体自身的文化自觉,促进“东方养生保健体育样式”的社会组织制度创新,使东方文明中传统

    Hutchins, Edwin

    2010-10-01

    Cognitive ecology is the study of cognitive phenomena in context. In particular, it points to the web of mutual dependence among the elements of a cognitive ecosystem. At least three fields were taking a deeply ecological approach to cognition 30 years ago: Gibson's ecological psychology, Bateson's ecology of mind, and Soviet cultural-historical activity theory. The ideas developed in those projects have now found a place in modern views of embodied, situated, distributed cognition. As cognitive theory continues to shift from units of analysis defined by inherent properties of the elements to units defined in terms of dynamic patterns of correlation across elements, the study of cognitive ecosystems will become an increasingly important part of cognitive science.

    2013-12-01

    This study examines how traditional ecological knowledge—TEK—can be identified and utilized to create culturally responsive science learning opportunities for Maya girls from a community in the Guatemalan highlands. Maya girls are situated in a complex socio-historical and political context rooted in racism and sexism. This study contextualizes the current situation of Maya women and girls in Guatemala and emphasizes the important need for educators to create science-learning opportunities that are culturally congruent. The author posits that when considering how to make the teaching and learning of science culturally responsive for Maya girls, educators must begin with the scientific knowledge inherent within Maya communities. Indigenous communities have a wealth of TEK that can be used to contextualize science curricula that can be purposely designed to meet the nuanced cultural needs of traditional Maya girls within and outside Guatemala.

    Classroom culture is the core element that affects the classroom teaching. A scientific knowledge of the classroom culture is the premier to improve the quality of classroom teaching. What's more, constructing"the classroom culture is also the key to the success of the classroom reform. Based on the perspective of the ecological philosophy, the classroom culture can be defined as"an ecosystem that is made up of teachers and students interaction with the classroom environment and the formation of values". The implication of this reveals that the classroom culture in essence is a kind of ecological system, mainly consisting of teachers, students and the classroom environment.%  课堂文化是影响课堂教学的核心因素,对课堂文化的科学认识是提高课堂教学质量的前提,变革课堂文化是教学改革成功的关键。以生态哲学为视角,课堂文化可定义为“师生以价值观为引领与课堂环境相互作用而形成的生态系统”,此内涵揭示了课堂文化的本质是一种生态系统,主要由有机体师生和课堂环境构成。

    Forbes, B. C.

    2013-12-01

    Empirical data on resilience in social-ecological systems (SESs) are reviewed from local and regional scale case studies among full-time nomads in the neighbouring Nenets and Yamal-Nenets Autonomous Okrugs, Russia. The focus is on critical cultural factors contributing to SES resilience. In particular, this work presents an integrated view of people situated in specific tundra landscapes that face significantly different prospects for adaptation depending on existing or planned infrastructure associated with oil and gas development. Factors contributing to general resilience are compared to those that are adapted to certain spatial and temporal contexts. Environmental factors include ample space and an abundance of resources, such as fish and game (e.g. geese), to augment the diet of not only the migratory herders, but also residents from coastal settlements. In contrast to other regions, such as the Nenets Okrug, Yamal Nenets households consist of intact nuclear families with high retention among youth in the nomadic tundra population. Accepting attitudes toward exogenous drivers such as climate change and industrial development appear to play a significant role in how people react to both extreme weather events and piecemeal confiscation or degradation of territory. Consciousness of their role as responsible stewards of the territories they occupy has likely been a factor in maintaining viable wildlife populations over centuries. Institutions administering reindeer herding have remained flexible, especially on Yamal, and so accommodate decision-making that is sensitive to herders' needs and timetables. This affects factors such as herd demography, mobility and energetics. Resilience is further facilitated within the existing governance regimes by herders' own agency, most recently in the post-Soviet shift to smaller, privately managed herds that can better utilize available pastures in a highly dynamic environment experiencing rapid socio-economic, climate and

    Full Text Available Since the mid-20th century, the Pyrenean pastoral social-ecological system (SES has undergone socioeconomic and demographic transformations leading to changes in grazing practices and a decline in the livestock industry. Land abandonment has contributed to an ecological transition from herbaceous vegetation cover to shrublands and forests, leading to a loss of ecosystem services, including biodiversity and forage. I interviewed 27 stockmen (ganaderos in two valleys of the central Pyrenees to document their traditional ecological knowledge and observations of environmental, social, economic, and cultural changes in the valleys. I used poetic analysis, a qualitative data analysis approach, to illustrate and analyze one ganadero's experience of social-ecological change. First, I created seven poems based on an interview transcript with this ganadero. Second, I analyzed the poetry I created, to see what new insights and understanding about system dynamics and the lived experience of SES change emerged from analysis of the transcript re-presented as poetry. Third, I compared key themes that emerged from this analysis with findings across the other 26 interviews. Fourth, I read the poems and presented the associated analysis to multiple audiences, to gauge their impact and effectiveness in communicating research findings. Finally, I synthesized across the themes raised in the seven poems. Poetic analysis revealed emotional and cultural dimensions of change, especially the importance of occupational and place identity, in the experience of the ganadero. The transcript re-presented as poetry portrayed the ganadero as an agent in creating and maintaining a cultural landscape and as both an adaptor and resister to SES change. Poetic analysis also uncovered telling contradictions, adaptive capacities, and barriers to adaptation in this SES that went unappreciated with conventional qualitative analysis approaches. This exploratory study illustrates the

These six, on average, demonstrated either the highest gain in knowledge and/or engagement in inquiry-based teaching or the lowest gain among all the novice science teachers through the year of participation in the PLC-MAP program. Certain patterns emerged across all six cases, even when the other variables are acknowledged. The principal external factors were school climate—its culture, its mandates, its degree of teacher autonomy. The internal factors were teacher beliefs about learning through inquiry, about their own need for additional knowledge, and about managing inquiry--all tied to degrees of self-efficacy.

    Monthly changes in sedimentation and sediment properties were studied for three different culture treatments: sea cucumber monoculture (Mc), sea cucumber and scallop polyculture (Ps-c) and scallop monoculture (Ms). Results indicated that the survival rate of sea cucumber was significantly higher in Ps-c cultures than in Mc cultures. Sea cucumber yield was 69.6% higher in Ps-c culture than in Mc culture. No significant differences in body weight and scallop shell length were found between Ps-c and Ms cultures. The mean sedimentation rate of total particulate matter (TPM) was 72.2 g/(m2·d) in Ps-c cultures, with a maximum of 119.7 g/(m2·d), which was markedly higher than that of Mc (mean value). Sedimentation rates of organic matter (OM), total organic carbon (TOC), total nitrogen (TN) and total phosphorus (TP) in Ps-c cultures were also significantly higher than those in Mc cultures. TOC and TN contents of sediment increased rapidly in the first 5 months in Ms cultures and remained at a high level. TOC and TN contents in Mc and Ps-c cultures decreased during sea cucumber feeding seasons and increased during sea cucumber dormancy periods (summer and winter). The study demonstrates that co-culture of sea cucumber and scallop in earthen ponds is an alternative way to alleviate nutrient loads and improve water quality in coastal aquaculture systems. Moreover, it provides the additional benefit of an increased sea cucumber yield.

    2011-01-01

    The National Research Council issued a report in 2009 that heavily criticized the forensic sciences. The report made several recommendations that if addressed would allow the forensic sciences to develop a stronger scientific foundation. We suggest a roadmap for decomposition ecology and forensic entomology hinging on a framework built on basic research concepts in ecology, evolution, and genetics. Unifying both basic and applied research fields under a common umbrella of terminology and structure would facilitate communication in the field and the production of scientific results. It would also help to identify novel research areas leading to a better understanding of principal underpinnings governing ecosystem structure, function, and evolution while increasing the accuracy of and ability to interpret entomological evidence collected from crime scenes. By following the proposed roadmap, a bridge can be built between basic and applied decomposition ecology research, culminating in science that could withstand the rigors of emerging legal and cultural expectations.

    Interdisciplinary study of coastal archaeological sites provides a wealth of information on the ecology and evolution of ancient marine animal populations, the structure of past marine ecosystems, and the history of human impacts on coastal fisheries. In this paper, we review recent methodological developments in the archaeology and historical ecology of coastal regions around the world. Using two case studies, we examine (a) a deep history of anthropogenic effects on the marine ecosystems of California's Channel Islands through the past 12,000 years and (b) geographic variation in the effects of human fishing on Pacific Island peoples who spread through Oceania during the late Holocene. These case studies--the first focused on hunter-gatherers, the second on maritime horticulturalists-provide evidence for shifting baselines and timelines, documenting a much deeper anthropogenic influence on many coastal ecosystems and fisheries than considered by most ecologists, conservation biologists, and fisheries managers.

    2011-01-01

    Ecology (from the Greek words οιχοσ, "house" and λογια "study of") is the science of the "house", since it studies the environments where we live. There are three main ways of thinking about Ecology: Ecology as the study of interactions (between humans and the environment, between humans and living beings, between all living beings, etc.), Ecology as the statistical study of interactions, Ecology as a faith, or rather as a science that requires a metaphysical view. The history of Ecology shows us how this view was released by the label of "folk sense" to gain the epistemological status of science, a science that strives to be interdisciplinary. So, the aim of Ecology is to study, through a scientific methodology, the whole natural world, answering to very different questions, that arise from several fields (Economics, Biology, Sociology, Philosophy, etc.). The plurality of issues that Ecology has to face led, during the Twentieth-century, to branch off in several different "ecologies". As a result, each one of these new approaches chose as its own field a more limited and specific portion of reality.

    Nazareth, J M

    1993-01-01

    At the end of the 19th century the German biologist Ernest Haekel was the first scientist to use the term ecology, which was defined as the study of relationships of organisms or groups of organisms with the environment and indicated the interdependence of the living world, including plants, animals, and humans. This concept also indicates a continuous process of adaptation of organisms to their external environment. The basic concepts of scientific ecology, which developed at the end of the 19th century, can be attributed to Darwin: the relationships between living beings and the notion of the process of adaptation to their environment. The term human ecology appeared in the early 1920s. Human ecology embodies fundamental ideas: biotype, habitat, community, biocenosis, ecosystem, biomass, interchange and equilibrium, and circulation of energy. The accumulated knowledge about human ecology is broken down using the criteria of topography (ecology of humid forests, deserts, lakes, etc.); followed by the appearance of species; and the variants of classical division: auto ecology (influence of external factors on living beings) and sinecology (the study of groups of associated organisms, i.e., natural, animal, and vegetation communities). The species are considered on the basis of equality or sinecology (all of them have the same interests), while in human ecology a species is determined by its relation to a reference group--autoecology or anthropocentric ecology. In 1911, J. Thompson bridged the gap between biological knowledge and social sciences; in 1921, H. Barrows identified human ecology as a component of geography; in 1925, L. Bernard presented the classification of ecosystems; and in 1936, Ezra Park published his work, Human Ecology, followed in 1945 by the emergence of the Chicago school. Demography and human ecology are intimately connected because population is the result of natural and migratory movements, therefore the two sciences require a methodology

    This study, framed by the component model of reading (CMR), examined the relative importance of kindergarten-entry predictors of first grade reading performance. Specifically, elements within the ecological domain included dialect, maternal education, amount of preschool, and home literacy; elements within the psychological domain included teacher-reported academic competence, social skills, and behavior; and elements within the cognitive domain included initial vocabulary, phonological, and morpho-syntactic skills, and alphabetic and word recognition skills. Data were obtained for 224 culturally diverse kindergarteners (58% Black, 34% White, and 8% Hispanic or other; 58% received free or reduced-price lunch) from a larger study conducted in seven predominantly high poverty schools (n = 20 classrooms) in a midsized city school district in northern Florida. Results from a hierarchical multiple regression (with variables in the ecological domain entered first, followed by the psychological and cognitive domains) revealed a model that explained roughly 56% of the variance in first grade reading achievement, using fall-of-kindergarten predictors. Letter-word reading and morpho-syntactic skill were the strongest significant predictors. The findings largely support the CMR model as a means to understand individual differences in reading acquisition and, in turn, to support data-based instructional decisions for a wider range of children.

    Stoate, C; Morris, R M; Wilson, J D

    2001-08-01

    The presence of Whitethroats and their potential invertebrate prey in farmland trees and shrubs was investigated. The management of this vegetation by farmers, and their motivation for that management, was explored using participatory techniques. Whitethroats were associated with Guiera senegalensis, the shrub species which supports most caterpillars and spiders. Farmers reported declines in trees and shrubs since the 1950s, loss of fallow areas, declines in soil fertility and crop yields, and increases in the use of fire for clearing fields. Trees are valued by people for their cultural and medicinal uses and some species used by Whitethroats and other birds have potential for restoring soil fertility, although this was not recognised by farmers. More sustainable use of savanna farmland could have both agronomic and wider conservation benefits, and the provision of information that accommodates farmers' cultural and economic incentives could benefit both farmers and wildlife.

    The current study presents the prevalence of students' reports of perpetration of violence toward peers and teachers among 16,604 7th- through 11th-grade Jewish and Arab students in Israel and examines the individual and school contextual factors that explain students' violence. The study explores how students' reports of violence are influenced by individual factors (gender, age, perception of school climate and intervention) and school contextual factors (cultural affiliation, SES of students' families, school and class size, school climate, intervention). Almost one third of all students reported at least one form of perpetration toward peers, and one in five reported perpetration against teachers. Compared to the school climate characteristics, school organizational factors, and cultural affiliation, students' SES has the highest contribution to explained variance in reports of violence toward others. The discussion highlights the need to allocate more resources to schools in low-SES contexts to protect low-SES students from school violence.

    1988-01-01

    Experiments were carried out on plant tissue cultures, seed germination, seedling development and plants grown on Simulated Lunar Soil to evaluate the potential of future development of lunar based agriculture. The studies done to determine the effect of the placement of SLS on tissue cultures showed no adverse effect of SLS on tissue cultures. Although statistically insignificant, SLS in suspension showed a comparatively higher growth rate. Observations indicate the SLS, itself cannot support calli growth but was able to show a positive effect on growth rate of calli when supplemented with MS salts. This positive effect related to nutritive value of the SLS was found to have improved at high pH levels, than at the recommended low pH levels for standard media. Results from seed germination indicated that there is neither inhibitory, toxicity nor stimulatory effect of SLS, even though SLS contains high amounts of aluminum compounds compared to earth soil. Analysis of seeding development and growth data showed significant reduction in growth rate indicating that, SLS was a poor growth medium for plant life. This was confirmed by the studies done with embryos and direct plant growth on SLS. Further observations attributed this poor quality of SLS is due to it's lack of essential mineral elements needed for plant growth. By changing the pH of the soil, to more basic conditions, the quality of SLS for plant growth could be improved up to a significant level. Also it was found that the quality of SLS could be improved by almost twice, by external supply of major mineral elements, directly to SLS.

    2016-01-01

    Fermented cucumber spoilage (FCS) characterized by rising pH and the appearance of manure and cheese like aromas is a challenge of significant economical impact for the pickling industry. Previous culture based studies identified the yeasts Pichia manshurica and Issatchenkia occidentalis, four gram positive bacteria, Lactobacillus buchneri, Lactobacillus parrafaraginis, Clostridium sp. and Propionibacterium and one gram-negative genus, Pectinatus as relevant in various stages of FCS given their ability to metabolize lactic acid. It was the objective of this study to augment the current knowledge of FCS using culture independent methods to microbiologically characterize commercial spoilage samples. Ion Torrent data and 16S rRNA cloning library analyses of samples collected from commercial fermentation tanks confirmed the presence of L. rapi and L. buchneri and revealed the presence of additional species involved in the development of FCS such as Lactobacillus namurensis, Lactobacillus acetotolerans, Lactobacillus panis, Acetobacter peroxydans, Acetobacter aceti, and Acetobacter pasteurianus at pH below 3.4. The culture independent analyses also revealed the presence of species of Veillonella and Dialister in spoilage samples with pH above 4.0 and confirmed the presence of Pectinatus spp. during lactic acid degradation at the higher pH. Acetobacter spp. were successfully isolated from commercial samples collected from tanks subjected to air purging by plating on Mannitol Yeast Peptone agar. In contrast, Lactobacillus spp. were primarily identified in samples of FCS collected from tanks not subjected to air purging for more than 4 months. Thus, it is speculated that oxygen availability may be a determining factor in the initiation of spoilage and the leading microbiota. Practical Application Understanding of the underlying microbiology and biochemistry driving FCS is essential to enhancing the sodium chloride (NaCl)-free cucumber fermentation technology and in

  15. On Theoretical Significances of“Ecological Civilization”from Perspective of“Cultural Maladies”%从“文弊”概念看“生态文明”的理论内涵

    将“生态文明”等同于“生态文化”不但大大削弱了“生态文明”这个术语所包含的对于“生态危机”的批判色彩,而且严重遮蔽了“生态文明”这个术语所包含的“生态价值观”的意义。从“价值观”出发可以看到“文化”包含着“文明”与“文弊”二重性,“文弊”概念对于界定“生态文明”的理论内涵具有三方面的作用:(1)明确辨析了“文化”与“文明”的联系与区别,有助于学术界进一步辨析“生态文化”与“生态文明”的联系与区别,从而促使“生态文明”这个概念更加清晰、合理,为国际社会普遍接受这个概念奠定更加坚实的理论基础;(2)突出了“生态文明”对于“文弊”的强烈批判性——批判现代工业文明及其哲学预设所导致的种种弊端,比如全球性生态危机、人的精神世界的荒漠化等;(3)突出了“生态文明”强烈的价值导向性——人类必须以生态价值观作为文明创造的根本原则,只有这样才能使人类文明避免饮鸩止渴那样愚蠢的自杀式发展道路。%Equating ecological civilization with ecological culture not only greatly weakens the critique on ecological crisis implied in the former term, but also seriously conceals the significance of ecological values it contains. From the perspective of values, culture contains civilization and cultural malady. The concept of cultural malady helps to define the theoretical significance of ecological civilization from three aspects. Firstly, it clearly discriminates connections and distinctions between culture and civilization, which helps to differentiate the concepts of ecological culture and ecological civilization so as to make the concept of ecological civilization clearer and more reasonable, which lays a solid theoretical foundation for the international community to generally accept it. Secondly, it highlights the

    Full Text Available La traducción se ha presentado como puente cultural, como medio neutral y democratizador al servicio de la comunicación y el intercambio intercultural. Tal función se realizaría de manera indiscriminada con respecto a la producción cultural de los espacios involucrados. Las teorías modernas la visualizan como una práctica selectiva, sujeta a intereses particulares, que ofrecen una visión sesgada del polo de partida. Este estudio muestra la función de embudo perpetuador de desequilibrios globales e imágenes predeterminadas que cumple la traducción y pone en entredicho el mito del puente cultural. Se da como ejemplo las traducciones de poesía costarricense durante el siglo XX, centradas en determinadas manifestaciones y escritores, a expensas de otros. Making no difference between cultural productions of either original or target contexts, translation has been viewed as a cultural bridge, a neutral and democratizing means at the service of communication and intercultural exchange. Modern theories now conceptualize this activity as a selective practice, one that is subject to particular interests and that offers an incomplete picture of the original context. Our objectives here are to show the function of translation as a funnel perpetuating global imbalances and pre-established images, and to question the myth of the cultural bridge. We analyze the case of twentieth-century Costa Rican poetry, in which translations focused almost exclusively on specific trends and poets, while others were left aside.

    2016-01-01

    A bridge in a graph is an edge whose removal disconnects the graph and increases the number of connected components. We calculate the fraction of bridges in a wide range of real-world networks and their randomized counterparts. We find that real networks typically have more bridges than their completely randomized counterparts, but very similar fraction of bridges as their degree-preserving randomizations. We define a new edge centrality measure, called bridgeness, to differentiate the importance of a bridge in damaging a network. We find that certain real networks have very large average and variance of bridgeness compared to their degree-preserving randomizations and other real networks. Finally, we offer an analytical framework to calculate the bridge fraction and average bridgeness for uncorrelated random networks with arbitrary degree distributions.

  6. Emergence Unites Ecology and Society

    Directory of Open Access Journals (Sweden)

    Ronald L. Trosper

    2005-06-01

    Full Text Available The effort to combine analysis of ecosystems and social systems requires a firm theoretical basis. When humans are present in an ecosystem, their actions affect emergent structures; this paper examines forms of emergence that account for the presence of humans. Humans monitor and regulate ecosystems based on their cultural systems. Cultural systems consist of concepts linked in complicated ways that can form consistent world views, can contain inconsistencies, and may or may not accurately model the properties of a social–ecological system. Consequently, human monitoring and regulating processes will differ, depending on cultural systems. Humans, as agents, change or maintain pre-existing material and cultural emergent structures. The presentation is illustrated with a case study of fire-prone forests. The paper shows that explicit attention to emergence serves very well in unifying the following requirements for social–ecological analysis: coherent and observable definitions of sustainability; ways to link ecological and social phenomena; ways to understand cultural reasons for stability and instability in dynamic social–ecological systems; and ways to include human self-evaluation and culture within dynamic models of social–ecological systems. Analysis of cultural emergent structures clarifies many differences in assumptions among the fields of economics, sociology, political science, ecology, and ecological economics. Because it can be readily applied to empirical questions, the framework provides a good way to organize policy analysis that is not dominated by one or another discipline.

This unique and beautifully lit bridge, which also breathes fire and sprays water. It’s the purposeful integration of the lighting hardware articulates the dragon’s form, and the fire-breathing dragon head. This project transcends the notion of monumental bridge with dynamic colour-changing lighting, creating an iconic sculpture in the skyline that is both reverent and whimsical. The signature feature of the bridge was the massive undulating support structure resembling a dragon flying over the river. The dragon is prominent in Vietnamese culture as a symbol of power and nobility. Dragon Bridge stands out as a model of innovation. It has received worldwide attention in the design community and from the global media for its unique arch support system. Dragon Bridge serves as an example of how aesthetic quality of a design can serve cultural, economic and functional purposes. The article presents design solutions of the object and the evaluation of the technical condition before putting the facility into service.

    Bruce C. Forbes

    2013-12-01

    Full Text Available Empirical data on resilience in social-ecological systems (SESs are reviewed from local and regional scale case studies among full-time nomads in the neighboring Nenets and Yamal-Nenets Autonomous Okrugs, Russia. The focus is on critical cultural factors contributing to SES resilience. In particular, this work presents an integrated view of people situated in specific tundra landscapes that face significantly different prospects for adaptation depending on existing or planned infrastructure associated with oil and gas development. Factors contributing to general resilience are compared to those that are adapted to certain spatial and temporal contexts. Environmental factors include ample space and an abundance of resources, such as fish and game (e.g., geese, to augment the diet of not only the migratory herders, but also residents from coastal settlements. In contrast to other regions, such as the Nenets Okrug, Yamal Nenets households consist of intact nuclear families with high retention among youth in the nomadic tundra population. Accepting attitudes toward exogenous drivers such as climate change and industrial development appear to play a significant role in how people react to both extreme weather events and piecemeal confiscation or degradation of territory. Consciousness of their role as responsible stewards of the territories they occupy has likely been a factor in maintaining viable wildlife populations over centuries. Institutions administering reindeer herding have remained flexible, especially on Yamal, and so accommodate decision-making that is sensitive to herders' needs and timetables. This affects factors such as herd demography, mobility and energetics. Resilience is further facilitated within the existing governance regimes by herders' own agency, most recently in the post-Soviet shift to smaller, privately managed herds that can better utilize available pastures in a highly dynamic environment experiencing rapid socio

    At present,many Chinese indigenous ecological culture projects enter into the production field, but their production resources or technologies their marketing production depends on are generally traditional and indigenous.These established and particular traditional resources or technologies are in conflict with some fac-tors of the monetary“homogenous”wealth (capital)of marketing economy path,which reflects the regularity of the indigenous ecological culture activities and development.This specifically includes the following three con-flicts:first,the segmentation and tension between the cultural value target and commercial value target of the o-riginal ecological culture;second,the confrontation and tension between the preservation of the originality and the consumptive reconstruction of the indigenous ecological culture;third,the contradictions and tension be-tween the preservation of the unique value and the universal diffuse of the indigenous ecological culture.Based on the above analysis,the paper concludes that the marketing development of the indigenous ecological culture should solve the problem caused by the dual target and task of cultural heritage and economic needs,establish the heritage and classic peculiarities of cultural carriers in the productive preservation,and make a balance be-tween tradition and modernization,thus keeping a moderate and appropriate development.%目前,我国不少原生态文化项目进入生产领域,但其市场性生产所依托的资源或技术一般是传统的。这些传统资源或技术是既定的和特殊性的,从而与货币性的“同质化”财富(资本)生产的市场经济路径之间的某些因素形成矛盾,体现了原生态文化产业化的特殊性,反映了原生态文化活动和发展的规律性。具体包括:文化自身价值目标与商业价值目标的分割和张力;原貌性保持与重构性消费之间的对立和张力;独特性价值保持与普适性传

    Chinese bamboo culture is not only closely related to people ’ s daily lives but also linked with their spiritual world. The environmental protection situation is becoming increasingly serious and the ecological civilization development needs promoting, so it is of great innovation value and significances to make a study on the ecological aesthetics of Chinese bamboo culture. The ecological aesthetics has overcome the barrier of binary opposition between the anthropocentrism and the ecocentrism and has achieved theoretically the harmony between man and nature, which provides important theoretical inspiration for sustainable development of today’s China. From the perspective of ecological aesthetics, this paper studies the rich ecological aesthetic ideology in Chinese bamboo culture and makes an in-depth analysis of the ecological and aesthetic functions of bamboo culture through connecting Chinese traditional culture with ecological aesthetics. Through the study of the interplay between bamboo ’s role on natural environment protection and its contribution to people ’ s spiritual civilization construction, this paper reveals the important role of bamboo on the harmonious relationship between man and nature, which is of great importance to protect and improve the natural environment we live by. In various forms such as landscape design, couplets and plaques, poems and paintings, Chinese bamboo culture theoretically reflects the Confucian ecological aesthetic ideal of“commitment to benevolence and perfection”and the Taoist ecological aesthetic realm of“Tao follows nature”, in line with the ecological conservation mentality in Chinese traditional culture. Therefore, the probe into the ecological aesthetic value of Chinese bamboo culture is not only beneficial to realize bamboo ’ s ecological conservation function but also helpful to provide new impetus to current ecological civilization construction.%中国“竹”文化与民众日常生活息息

    As attributes of the Earth's ecosystems shift in the face of human impact and sustainability of ecosystem services becomes less certain, one important tool at the disposal of the scientific community and other groups is a blueprint for understanding, evaluating, and communicating the value of ecological services. The blueprint presented here is based on (1) an examination of the ecological and societal trade-offs accompanying any given action, (2) revised methods of communication, and (3) coordination of actions at many different scales. The Mexican National Commission for the Knowledge and Use of Biodiversity (CONABIO) is a good example of a demand-driven “bridging institution” between academia, government, and civil society, and it works to collect and convert scientific information into information for policy, management, and conservation. Intergovernmental organizations like the United Nations Educational, Scientific and Cultural Organization (UNESCO) are well placed to facilitate such coordination at the international level, through their work with member states. Through collaboration with the constituencies of such organizations as the Ecological Society of America, the blueprint described below has the potential to become an important tool for assessing and managing threats to ecosystem services that are essential to life.

    The historical and cultural theme parks, a brand-new tourist product, are usually built based on the cultural and historical resources of a city. On one hand, the development of the park can not only promote the evolution of urban ecological civilization but also be helpful for boosting the reputation of the city and the initiation of green tour. On the other hand, the sound development of urban ecology can have a positive effect on development and preservation of historical heritage. The paper is based on the study on the relationship between historical and cultural theme park and the development of urban ecology. It mainly makes discussion on the interaction of the two and puts forward the ideas on promoting their mutual development.%历史文化主题公园作为一种崭新的旅游产品,依托于城市的人文历史资源进行兴建和开发,不仅能促进城市生态文明深度发展,而且有助于强化城市的生态形象和构建城市绿色旅游。城市生态发展的重视不仅能够推进历史文化主题公园的建设,而且对历史文化遗产的开发和保护产生积极地影响。研究立足于历史文化主题公园和城市生态发展的内在关系,着重从两者的相互作用进行讨论,并提出优化的路径构想,旨在实现历史文化主题公园与城市生态文明共发展。

It has given birth to the farmers groups to planting specialty agriculture products for the Jiangxi's traditional farming culture. For the blending of the traditional agricultural culture and modern commercial culture, it has given birth to various forms of economic cooperation organizations.Moreover, as the regional cultural embeddedness, it can reduce the transaction costs among the farmers, or between farmers and business; as the social capital of the regional culture, it can also increase transaction income. It is very important for cluster development with the optimization of the cultural ecology from internal and external structure as well as the integration of local and extra culture, which has been explained by taking Silke Fowl industrial cluster in Taihe county of Jiangxi as example.

    This collection of essays brings together a diverse group of scholars to survey the latest strategies for solving ecological inference problems in various fields. The last half-decade has witnessed an explosion of research in ecological inference--the process of trying to infer individual behavior from aggregate data. Although uncertainties and information lost in aggregation make ecological inference one of the most problematic types of research to rely on, these inferences are required in many academic fields, as well as by legislatures and the Courts in redistricting, by business in marketing research, and by governments in policy analysis.

    Please note this is a Short Discount publication. As LANs have proliferated, new technologies and system concepts have come to the fore. One of the key issues is how to interconnect networks. One means of interconnection is to use a 'bridge'. Other competing technologies are repeaters, routers, and gateways. Bridges permit traffic isolation, connect network segments together and operate at the MAC layer. Further, because they operate at the MAC layer, they can handle a variety of protocols such as TCP/IP, SNA, and X.25. This report focuses on the specific technology of bridging two netw

    For more than 50,000 years, Indigenous Australians have incorporated celestial events into their oral traditions and used the motions of celestial bodies for navigation, time-keeping, food economics, and social structure. In this paper, we explore the ways in which Aboriginal people made careful observations of the sky, measurements of celestial bodies, and incorporated astronomical events into complex oral traditions by searching for written records of time-keeping using celestial bodies, the use of rising and setting stars as indicators of special events, recorded observations of variable stars, the solar cycle, and lunar phases (including ocean tides and eclipses) in oral tradition, as well as astronomical measurements of the equinox, solstice, and cardinal points.

    1988-01-01

    This book presents the proceedings of a workshop on community ecology organized at Davis, in April, 1986, sponsored by the Sloan Foundation. There have been several recent symposia on community ecology (Strong et. al., 1984, Diamond and Case, 1987) which have covered a wide range of topics. The goal of the workshop at Davis was more narrow: to explore the role of scale in developing a theoretical approach to understanding communities. There are a number of aspects of scale that enter into attempts to understand ecological communities. One of the most basic is organizational scale. Should community ecology proceed by building up from population biology? This question and its ramifications are stressed throughout the book and explored in the first chapter by Simon Levin. Notions of scale have long been important in understanding physical systems. Thus, in understanding the interactions of organisms with their physical environment, questions of scale become paramount. These more physical questions illustrate the...

  1. Germ Cell Intercellular Bridges

    Science.gov (United States)

    Greenbaum, Michael P.; Iwamori, Tokuko; Buchold, Gregory M.; Matzuk, Martin M.

    2011-01-01

    Stable intercellular bridges are a conserved feature of gametogenesis in multicellular animals observed more than 100 years ago, but their function was unknown. Many of the components necessary for this structure have been identified through the study of cytokinesis in Drosophila; however, mammalian intercellular bridges have distinct properties from those of insects. Mammalian germ cell intercellular bridges are composed of general cytokinesis components with additional germ cell–specific factors including TEX14. TEX14 is an inactive kinase essential for the maintenance of stable intercellular bridges in gametes of both sexes but whose loss specifically impairs male meiosis. TEX14 acts to impede the terminal steps of abscission by competing for essential component CEP55, blocking its interaction in nongerm cells with ALIX and TSG101. Additionally, TEX14-interacting protein RBM44, whose localization in stabile intercellular bridges is limited to pachytene and secondary spermatocytes, may participate in processes such as RNA transport but is nonessential to the maintenance of intercellular bridge stability.

    2014-01-01

    Biologists have assumed that heritable variation due to DNA sequence differences (i.e., genetic variation) allows populations of organisms to be both robust and adaptable to extreme environmental conditions. Natural selection acts on the variation among different genotypes and ultimately changes the genetic composition of the population. While there is compelling evidence about the importance of genetic polymorphisms, evidence is accumulating that epigenetic mechanisms (e.g., chromatin modifications, DNA methylation) can affect ecologically important traits, even in the absence of genetic variation. In this chapter, we review this evidence and discuss the consequences of epigenetic variation in natural populations. We begin by defining the term epigenetics, providing a brief overview of various epigenetic mechanisms, and noting the potential importance of epigenetics in the study of ecology. We continue with a review of the ecological epigenetics literature to demonstrate what is currently known about the amount and distribution of epigenetic variation in natural populations. Then, we consider the various ecological contexts in which epigenetics has proven particularly insightful and discuss the potential evolutionary consequences of epigenetic variation. Finally, we conclude with suggestions for future directions of ecological epigenetics research.

    1997-01-01

    New developments are constantly introduced in the search for the optimal treatment modality to restore a single anterior tooth. The patient attention has shifted to aesthetics of the restoration, biocompatibility of the dental materials utilized, conservative preparation of the teeth to be restored, and the retention of intact adjacent dentition. The learning objective of this article is to review the methods currently utilized and to present a recently introduced treatment modality--the two-component bridge, which combines the strength and resiliency of composite resin with the aesthetic advantages of porcelain. The technology of the material is reviewed, the predominantly lingual tooth preparation procedures are outlined, and the bridge try-in is described. The advantages of the two-component bridge are presented along with the contraindications and suggestions of careful case selection. Three cases with congenitally missing maxillary lateral incisors in youthful patients are presented to supplement the theoretical outline and to describe and illustrate the clinical procedure.

  11. Call cultures in orang-utans?

    Directory of Open Access Journals (Sweden)

    Serge A Wich

    Full Text Available BACKGROUND: Several studies suggested great ape cultures, arguing that human cumulative culture presumably evolved from such a foundation. These focused on conspicuous behaviours, and showed rich geographic variation, which could not be attributed to known ecological or genetic differences. Although geographic variation within call types (accents has previously been reported for orang-utans and other primate species, we examine geographic variation in the presence/absence of discrete call types (dialects. Because orang-utans have been shown to have geographic variation that is not completely explicable by genetic or ecological factors we hypothesized that this will be similar in the call domain and predict that discrete call type variation between populations will be found. METHODOLOGY/PRINCIPAL FINDINGS: We examined long-term behavioural data from five orang-utan populations and collected fecal samples for genetic analyses. We show that there is geographic variation in the presence of discrete types of calls. In exactly the same behavioural context (nest building and infant retrieval, individuals in different wild populations customarily emit either qualitatively different calls or calls in some but not in others. By comparing patterns in call-type and genetic similarity, we suggest that the observed variation is not likely to be explained by genetic or ecological differences. CONCLUSION/SIGNIFICANCE: These results are consistent with the potential presence of 'call cultures' and suggest that wild orang-utans possess the ability to invent arbitrary calls, which spread through social learning. These findings differ substantially from those that have been reported for primates before. First, the results reported here are on dialect and not on accent. Second, this study presents cases of production learning whereas most primate studies on vocal learning were cases of contextual learning. We conclude with speculating on how these findings might

    2016-12-01

    The article describes general principles and basis of evaluation of existing railway bridges based on the concept of load-carrying capacity determination. Compared to the design of a new bridge, the modified reliability level for existing bridges evaluation should be considered due to implementation of the additional data related to bridge condition and behaviour obtained from regular inspections. Based on those data respecting the bridge remaining lifetime, a modification of partial safety factors for actions and materials could be respected in the bridge evaluation process. A great attention is also paid to the specific problems of determination of load-caring capacity of steel railway bridges in service. Recommendation for global analysis and methodology for existing steel bridge superstructure load-carrying capacity determination are described too.

    Using net enclosures in an earthen pond, we established three culture treatments with the sea cucumber Apostichopus japonicus and the Chinese white shrimp Fenneropenaeus chinensis: monoculture of sea cucumbers (C), monoculture of shrimp (S), and co-culture of the two species (CS). We measured levels of suspended particulate matter in the water column; total organic matter, total organic carbon, total nitrogen, and carbon/nitrogen ratios in both settling particles and the sediment; and chlorophyll a levels in the sediment. We then compared these variables between the three treatments. We also examined growth, survival, and yield of the two species in the different treatments. From June to September, the mean monthly suspended particulate matter sedimentation rates in the CS and S treatments were significantly ( Porganic matter, total organic carbon, total nitrogen, and chlorophyll a contents in the sediment in the CS and S treatments were significantly ( P food for the sea cucumbers. Co-culture of the two species is a viable option for increasing yield per unit area, maximizing use of the water body, and diversifying crop production.

    The one-dimensional developism based on the mode of linear thinking does more harm than good to human society. The pursuit for modernization and acceleration of globalization destroys the plurality of world culture. The bitter historical experience makes China go to extremes in its pursuit for development without giving much thought to the danger of impoverishing its own traditional culture. This caused Chinese cultural ecological environment to deteriorate. As a result, its internal cultural quality and spiritual power fall drastically. Culture is the foundation for the rise of a nation. The renaissance of a nation in the process of modernization can not happen without the support of the revival of the whole national culture and without sustenance of cultural energy. As China strengthens its reformation, we should try to adjust the symbiotic relationship between economy, politics, society and culture by way of institutional practice and scientific development. We should also greatly improve the system and function of our governance. We must take the historical responsibility and try our best to unleash our cultural vitality and creativity and guard the cultural justice against all possible violations.%建立在线性思维基础上的、单一模式的“发展主义”对人类社会来说是祸而非福。现代化追求与全球化深入的偏颇损害了世界文化的多样性,崇信现代化的中国因历史的负债而不可避免地“矫枉过正”,一再损耗着原本厚实与多样的中华文化,使其文化生态日趋恶化,其内在品质与精神影响力大幅度下降。文化是一个民族实现跨越式发展的重要基础,一个民族要想在现代化进程中实现伟大复兴,没有文化的整体复兴作为拱卫、没有文化的深度活力进行反哺是难以为继的。全面深化改革背景下的当代中国,要努力通过制度实践和科学发展,更好地协调经济、政治、社会、文化之间的

  5. Historical ecology: past, present and future.

    Science.gov (United States)

    Szabó, Péter

    2015-11-01

    The term 'historical ecology' has been used with various meanings since the first half of the 20th century. Studies labelled as historical ecology have been produced in at least four academic disciplines: history, ecology, geography and anthropology. Although all those involved seem to agree that historical ecology concerns the historical interconnectedness of nature and human culture, this field of study has no unified methodology, specialized institutional background and common publication forums. Knowledge of the development of historical ecology is also limited. As a result, the current multitude of definitions of historical ecology is accompanied by divergent opinions as to where the origins of the field are to be sought. In this review, I follow the development of historical ecology from the 18th century to the present. In the first part, I briefly describe some early examples of historical ecological investigations, followed by a description of the various scientific strands in the 20th century that contributed to the formation of historical ecology. In the second part, I discuss the past five decades of historical ecological investigations in more detail, focusing mostly (but not exclusively) on works that their respective authors identified as historical ecology. I also examine the appearance and interconnectedness of the two main trends (ecological and anthropological) in historical ecological research. In the last part, I attempt to outline the future of historical ecology based on common features in existing research. It appears that at present historical ecology is at a crossroads. With rapidly growing interest in historical ecological research, it may move towards institutionalization or remain an umbrella term.

  6. Dynamic Bridge Response for a Bridge-friendly Truck

    Full Text Available A truck with controlled semi-active suspensions traversing a bridge is examined for benefits to the bridge structure. The original concept of a road-friendly truck was extended to a bridge-friendly vehicle, using the same optimization tools. A half-car model with two independently driven axles is coupled with simply supported bridges (beam, slab model with the span range from 5 m to 50 m. Surface profile of the bridge deck is either stochastic or in the shape of a bump or a pot in the mid-span. Numerical integration in the MATLAB/SIMULINK environment solves coupled dynamic equations of motion with optimized truck suspensions. The rear axle generates the prevailing load and to a great extent determines the bridge response. A significant decrease in contact road-tire forces is observed and the mid-span bridge deflections are on average smaller, when compared to commercial passive suspensions.

    We propose simple methods for multivariate diffusion bridge simulation, which plays a fundamental role in simulation-based likelihood and Bayesian inference for stochastic differential equations. By a novel application of classical coupling methods, the new approach generalizes a previously...... proposed simulation method for one-dimensional bridges to the mulit-variate setting. First a method of simulating approzimate, but often very accurate, diffusion bridges is proposed. These approximate bridges are used as proposal for easily implementable MCMC algorithms that produce exact diffusion bridges...

    A micro-ecological fodder starter culture lactic acid bacterial strain was screened and the culture conditions were optimized in this article. The acid production rate of three kinds of lactic acid bacteria was determined, and the antibacterial test for e.coli was carried out. Meanwhile the excellent strains were identified by using French bacteria identification system. The result shows that the acid production rate of type A lactic acid bacteria was fast, with good antibacterial effect. And the type A lactic acid bacteria was identified as Pediococcus pentosus. By studying the effect of each culture con⁃dition on biomass of lactic acid bacteria, we reached that the culture temperature was 30 ℃, stilling culture, inoculum size was 1%, choosing peptone as nitrogen source with the concentration of 8%~10%, the initial pH was 6.5. Under this condition, the biomass of lactic acid bacteria was the highest. These provided a theoretical reference for development and application of micro-ecological fodder start⁃er culture strains.%对用于微生态饲料发酵剂的乳酸菌进行筛选和培养条件优化。测定了3种乳酸菌的产酸速度,进行了大肠杆菌的抑菌效果试验,并利用梅里埃细菌鉴定系统对优良菌种进行鉴定,得出A型乳酸菌的产酸速度快、抑菌效果好,并鉴定该菌为戊糖片球菌;通过研究培养条件诸因素对乳酸菌生物量的影响,研究得出:培养温度30℃、静置培养、接种量1%、氮源选择蛋白胨、碳源浓度为8%~10%、初始pH值为6.5,该条件下乳酸菌的生物量最大。为微生物饲料发酵剂菌种的开发与应用提供理论参考。

  10. Conversion of midbodies into germ cell intercellular bridges

    Science.gov (United States)

    Greenbaum, Michael P.; Ma, Lang; Matzuk, Martin M.

    2009-01-01

    Whereas somatic cell cytokinesis resolves with abscission of the midbody, resulting in independent daughter cells, germ cell cytokinesis concludes with the formation of a stable intercellular bridge interconnecting daughter cells in a syncytium. While many proteins essential for abscission have been discovered, until recently, no proteins essential for mammalian germ cell intercellular bridge formation have been identified. Using TEX14 as a marker for the germ cell intercellular bridge, we show that TEX14 co-localizes with the centralspindlin complex, mitotic kinesin-like protein 1 (MKLP1) and male germ cell Rac GTPase-activating protein (MgcRacGAP), and converts these midbody matrix proteins into stable intercellular bridge components. In contrast, septins (SEPT) 2, 7, and 9 are transitional proteins in the newly forming bridge. In cultured somatic cells, TEX14 can localize to the midbody in the absence of other germ cell specific factors, suggesting that TEX14 serves to bridge the somatic cytokinesis machinery to other germ cell proteins to form a stable intercellular bridge essential for male reproduction.

    In this paper we discuss the notion of "bridging" in Discourse Representation Theory as a tool to account for discourse referents that have only been established implicitly, through the lexical semantics of other referents. In doing so, we use ideas from Generative Lexicon theory, to introduce antecedents for anaphoric expressions that cannot be "linked" to a proper antecedent, but that do not need to be "accommodated" because they have some connection to the network of discourse referents that is already established.

    Full Text Available This essay describes strategic approaches to graphic representation associated with critical environmental engagement and that build from the idea of works of architecture as stitches in the ecological fabric of the city. It focuses on the building up of partial or fragmented graphics in order to describe inclusive, open-ended possibilities for making architecture that marry rich experience and responsive performance. An aphoristic approach to crafting drawings involves complex layering, conscious absence and the embracing of tension. A self-critical attitude toward the generation of imagery characterized by the notion of ‘loose precision’ may lead to more transformative and environmentally responsive architectures.

    In human-dominated landscapes, interactions and perceptions towards wildlife are influenced by multidimensional drivers. Understanding these drivers could prove useful for wildlife conservation. We surveyed the attitudes and perceptions of fishers towards threatened Irrawaddy dolphins (Orcaella brevirostris) at Chilika Lagoon India. To validate the drivers of fisher perceptions, we : (1) observed dolphin foraging behavior at stake nets, and (2) compared catch per unit effort (CPUE) and catch income of fishers from stake nets in the presence and absence of foraging dolphins. We found that fishers were mostly positive towards dolphins, believing that dolphins augmented their fish catch and using culture to express their perceptions. Foraging dolphins were observed spending half their time at stake nets and were associated with significantly higher catch income and CPUE of mullet (Liza sp.), a locally preferred food fish species. Wildlife conservation efforts should use the multidimensional drivers of human-wildlife interactions to involve local stakeholders in management.

  18. Civic Ecology: A Postmodern Approach to Ecological Sustainability

    Science.gov (United States)

    Lopes, V. L.

    2013-12-01

    Human agency is transforming the planetary processes at unprecedented rates risking damaging essential life-support systems. Climate change, massive species extinction, land degradation, resources depletion, overpopulation, poverty and social injustice are all the result of human choices and non-sustainable ways of life. The survival of our modern economic systems depends upon insatiable consumption - a simple way of life no longer satisfies most people. Detached, instrumental rationality has created an ideal of liberalism based on individual pursuit of self-interest, leading the way into unprecedented material progress but bringing with it human alienation, social injustice, and ecological degradation. The purpose of this presentation is to introduce a community-based systems response to a growing sense that the interlocked social-ecological crisis is as much a problem of human thought and behavior as it is about identifying carrying capacities and CO2 concentrations in the atmosphere. This approach, referred to here as civic ecology, presents a new and important paradigm shift in sustainability practice that attempts to bring together and integrate ecological ideas and postmodern thinking. As such, it is as much a holistic, dynamic, and synergistic approach to ecological sustainability, as it is a philosophy of life and ethical perspective born of ecological understanding and insight. Civic ecology starts with the proposition that the key factor determining the health of the ecosphere is the behavior of human beings, and therefore many of the most important issues related to sustainability lie in the areas of human thought and culture. Thus, the quest for sustainability must include as a central concern the transformation of psychological and behavioral patterns that have become an imminent danger to planetary health. At the core of this understanding is a fundamental paradigm shift from the basic commitments of modern Western culture to its model of mechanism

    2014-07-01

    Full Text Available From educational gaming through portable e-readers to cell phones, media are interpenetrating educational spaces and activities. Accordingly, understanding media in environmental or ecological terms has become increasingly important for education internationally. In North America, for example, the centenary of McLuhan’s birth has focused attention on approaches to media – whether oral, textual, electronic or digital– as a kind of environment in which education takes place. In parts of Europe, the so-called mediatic turn – following on the linguistic and iconic turns – has similarly emphasized the role of media as a condition for the possibility of educational activities and programs. With a few exceptions1 the papers in this special issue were first presented at the conference «Educational Media Ecologies: International Perspectives» which took place at the University of Paderborn, Germany, on March 27–28, 2012.2 The event was an interdisciplinary and transatlantic endeavor to bring together a wide range of perspectives on various issues relevant to educational media ecologies,3 and on related debates on mediation, medialization, mediatization, and mediality.4 The purpose of this volume, like the conference, is to foster and deepen international dialogue in the area of educational media. Areas of research and scholarship relevant to this dialogue include educational media, media literacy, educational philosophy, and media and cultural studies. The contributions, described below, put conceptual issues as well as social practices and applications at the center of the debate. Klaus Rummler opens the issue by clarifying the concept of ecology itself. Referencing a range of work over the past 50 years, Rummler describes how ecological models have been cast in sociological, semiotic, cultural, mediatic and other terms, and he explains the implications of these various perspectives for the study of educational contexts.

    In 2003, a non-profit group, Ka Mate Nga Kiore, was set up to oversee the restoration of four Maori-owned islands off the south coast of Stewart Island, New Zealand. The first step in the restoration was to eradicate ship rats (Rattus rattus) from three islands and Pacific rats (R. exulans) from another. The eradication was funded by the Command Oil Spill Trustee Council which managed the mitigation money from an oil spill off the Californian coast in 1998. The funding was coordinated via Oikonos Ecosystem Knowledge, a non-profit USA group primarily involved in seabird research and restoration. The project was primarily to benefit sooty shearwater (Puffinus griseus) and to sustain a culturally important customary harvest of their chicks by Rakiura Maori. However, like all island eradications, a wide range of other species also benefited from the removal of rats. The New Zealand Department of Conservation provided technical advice and assistance for the planning and implementation of the eradication programme. This paper describes how, with appropriate funding, community and technical support, rodent eradications can be achieved on private islands. In this case, a range of institutions and individuals joined to achieve a common goal that highlighted a significant international conservation action. We urge that more international and local-community-led restoration projects be initiated in the future.

    Bartonella melophagi sp. nov. was isolated from domestic sheep blood and from sheep keds (Melophagus ovinus) from the southwestern United States. The sequence analyses of the reference strain performed by six molecular markers consistently demonstrated that B. melophagi relates to but differ from other Bartonella species isolated from domestic and wild ruminants. Presence of 183 genes specific for B. melophagi, being absent in genomes of other Bartonella species associated with ruminants also supports the separation of this bacterial species from species of other ruminants. Bartonella DNA was detected in all investigated sheep keds; however, culturing of these bacteria from sheep blood rejects a speculation that B. melophagi is an obligatory endosymbiont. Instead, the results support the hypothesis that the domestic sheep is a natural host reservoir for B. melophagi and the sheep ked its main vector. This bacterium was not isolated from the blood of bighorn sheep and domestic goats belonging to the same subfamily Caprinae. B. melophagi has also been shown to be zoonotic and needs to be investigated further.

    2009-09-01

    Global human progress occurs in a complex web of interactions between society, technology and the environment as driven by governance and infrastructure management capacity among nations. In our globalizing world, this complex web of interactions over the last 200 years has resulted in the chronic widening of economic and political gaps between the haves and the have-nots with consequential global cultural and ecosystem challenges. At the bottom of these challenges is the issue of resource limitations on our finite planet with increasing population. The problem is further compounded by pleasure-driven and poverty-driven ecological depletion and pollution by the haves and the have-nots respectively. These challenges are explored in this paper as global sustainable development (SD) quantitatively; in order to assess the gaps that need to be bridged. Although there has been significant rhetoric on SD with very many qualitative definitions offered, very few quantitative definitions of SD exist. The few that do exist tend to measure SD in terms of social, energy, economic and environmental dimensions. In our research, we used several human survival, development, and progress variables to create an aggregate SD parameter that describes the capacity of nations in three dimensions: social sustainability, environmental sustainability and technological sustainability. Using our proposed quantitative definition of SD and data from relatively reputable secondary sources, 132 nations were ranked and compared. Our comparisons indicate a global hierarchy of needs among nations similar to Maslow's at the individual level. As in Maslow's hierarchy of needs, nations that are struggling to survive are less concerned with environmental sustainability than advanced and stable nations. Nations such as the United States, Canada, Finland, Norway and others have higher SD capacity, and thus, are higher on their hierarchy of needs than nations such as Nigeria, Vietnam, Mexico and other

    Although some myocardial bridges can be asymptomatic, their presence often causes coronary disease either through direct compression of the "tunnel" segment or through stimulation and accelerated development of atherosclerosis in the segment proximally to the myocardial bridge. The studied material contained 30 human hearts received from the Department of Anatomy. The hearts were preserved 3 to 5 days in 10% formalin solution. Thereafter, the fatty tissue was removed and arterial blood vessels prepared by careful dissection with special reference to the presence of the myocardial bridges. Length and thickness of the bridges were measured by the precise electronic caliper. The angle between the myocardial bridge fibre axis and other axis of the crossed blood vessel was measured by a goniometer. The presence of the bridges was confirmed in 53.33% of the researched material, most frequently (43.33%) above the anterior interventricular branch. The mean length of the bridges was 14.64 ± 9.03 mm and the mean thickness was 1.23 ± 1.32 mm. Myocardial bridge fibres pass over the descending blood vessel at the angle of 10-90 degrees. The results obtained on a limited sample suggest that the muscular index of myocardial bridge is the highest for bridges located on RIA, but that the difference is not significant in relation to bridges located on other branches. The results obtained suggest that bridges located on other branches, not only those on RIA, could have a great contractive power and, consequently, a great compressive force, which would be exerted on the wall of a crossed blood vessel.

    The UK has a long history in the railway industry with a large number of railway assets. Railway bridges form one of the major asset groups with more than 35,000 bridges. The majority of the bridge population are old being constructed over 100 years ago. Many of the bridges were not designed to meet the current network demand. With an expected increasing rate of deterioration due to the increasing traffic loads and intensities, the management authorities are faced with the difficult task of k...

  11. The Ecology of Human Mobility

    Meekan, Mark G.

    2017-02-03

    Mobile phones and other geolocated devices have produced unprecedented volumes of data on human movement. Analysis of pooled individual human trajectories using big data approaches has revealed a wealth of emergent features that have ecological parallels in animals across a diverse array of phenomena including commuting, epidemics, the spread of innovations and culture, and collective behaviour. Movement ecology, which explores how animals cope with and optimize variability in resources, has the potential to provide a theoretical framework to aid an understanding of human mobility and its impacts on ecosystems. In turn, big data on human movement can be explored in the context of animal movement ecology to provide solutions for urgent conservation problems and management challenges.

  13. Culture and the socialization of child cardiovascular regulation at school entry in the US.

    DeCaro, Jason A; Worthman, Carol M

    2008-01-01

    The measurement of cardiovascular functioning targets an important bridge between social conditions and differential well-being. Nevertheless, the biocultural, psychosocial processes that link human ecology to cardiovascular function in children remain inadequately characterized. Childrearing practices shaped by parents' cultural beliefs should moderate children's affective responses to daily experience, and hence their psychophysiology. The present study concerns interactions among family ecology, the normative social challenge of entry into kindergarten, and parasympathetic (vagal) cardiac regulation in US middle-class children (N = 30). Although parents believed children must be protected from overscheduling to reduce stress and improve socio-emotional adaptation, maternal rather than child schedules predicted parasympathetic regulation during a nonthreatening social engagement task following school entry. Children of busier married mothers, but less busy single mothers, showed the context-appropriate pattern of parasympathetic regulation, low respiratory sinus arrhythmia (RSA). These findings are expected if: maternal and family functioning, rather than the scheduling of the child's daily life, principally drive young children's cardiovascular responsiveness to a normative challenge; and busy schedules represent high family functioning with married mothers, but not under single-parent conditions wherein adult staffing is uniquely constrained. Family ecology is shaped by culture, and in turn shapes the development of children's cardiovascular responses. Appropriately fine-grained analysis of daily experience can illustrate how culturally driven parenting practices may have unintended consequences for child biological outcomes that vary by family structure.

    Wordsworth devoted himself to the ideal of a harmonious relation between human and nature, between man and soci-ety, between man and the ego. In this sense, Wordsworth improved the development of ecology. This argument will be support-ed by the approach of eco-criticism and Heidegger’s eco-philosophy. And it is supported by the following points.The first part points out that Wordsworth’s love of nature led to his love of man, which was reflected by his care for common people. Part Two shows Wordsworth’s solicitude for dwelling. His notion of dwelling had aspect of poetic dwelling. The harmonious hu-man-nature relationship reveals thee essence of free dwelling. His poetic experiment agreed with Heidegger ’s argument on poet-ic creation. His discussion of free labour was like Heidegger’s interpretation of“merit”. Part Three tells about Wordsworth’s great effort to amend the alienated human nature by treasuring the Child’s nature, imagination and human feelings.In this way, the conclusion can be got:although it would be a huge project to reinterpret Wordsworth with the approaches of eco-criticism and Heidegger’s eco-philosophy, it is still worth making the effort.

    Full Text Available Discussions about what constitutes ‘the rural’ invariably focus on notions of spatial location – of inhabiting spaces apart from that of the metropolitan. Deeply embedded in our images of what it means to be Australian, nonetheless our intellectual framing of ‘the rural’ as something outback and beyond has significant implications for our relations with these spaces. The relatively recent phenomenon of sea- and tree-changes has struck many unawares, and not simply because a good latté is so hard to find. Although a frivolous remark, such an apparent lack does shift our focus to a bodily scale of the rural; how is rural place re/made through our experiences of it? This article originates out of on-going research that explores the practice of listening and sound and the ways in which the body can draw attention to the intuitive, emotional, and psychoanalytical processes of subjectivity and place-making. Drawing on Nigel Thrift’s concept of an ecology of place, I suggest that contemporary heightened concerns with regards to loss and lack in rural Australia has led to a nascent emotional economy – one in which individual and intimate connections to the rural require a rethinking of how we live community and belonging. In such a terrain, what does it mean to be rural?

  20. Interdisciplinary Adventures in Perceptual Ecology

    Science.gov (United States)

    Bocast, Christopher S.

    A portfolio dissertation that began as acoustic ecology and matured into perceptual ecology, centered on ecomusicology, bioacoustics, and translational audio-based media works with environmental perspectives. The place of music in Western eco-cosmology through time provides a basis for structuring an environmental history of human sound perception. That history suggests that music may stabilize human mental activity, and that an increased musical practice may be essential for the human project. An overview of recent antecedents preceding the emergence of acoustic ecology reveals structural foundations from 20th century culture that underpin modern sound studies. The contextual role that Aldo Leopold, Jacob von Uexkull, John Cage, Marshall McLuhan, and others played in anticipating the development of acoustic ecology as an interdiscipline is detailed. This interdisciplinary aspect of acoustic ecology is defined and defended, while new developments like soundscape ecology are addressed, though ultimately sound studies will need to embrace a broader concept of full-spectrum "sensory" or "perceptual" ecology. The bioacoustic fieldwork done on spawning sturgeon emphasized this necessity. That study yielded scientific recordings and spectrographic analyses of spawning sounds produced by lake sturgeon, Acipenser fulvescens, during reproduction in natural habitats in the Lake Winnebago watershed in Wisconsin. Recordings were made on the Wolf and Embarrass River during the 2011-2013 spawning seasons. Several specimens were dissected to investigate possible sound production mechanisms; no sonic musculature was found. Drumming sounds, ranging from 5 to 7 Hz fundamental frequency, verified the infrasonic nature of previously undocumented "sturgeon thunder". Other characteristic noises of sturgeon spawning including low-frequency rumbles and hydrodynamic sounds were identified. Intriguingly, high-frequency signals resembling electric organ discharges were discovered. These

    2008-01-01

    Cooperative system bridges comprise several basic structures that act jointly to improve structural characteristics. We delved into the historical development of cooperative system bridges. Cooperative systems are classified as different-load cooperative systems and same-load cooperative systems by distinguishing the modes of load distribution. For different-load cooperation, individual basic structures are at different positions in the direction along bridge axis and carry the loads separately. While for same-load cooperation, all basic structures overlap in geometrical locations and support the entire loads conjointly. The choosing of span ratios between basic structures, the design of connections of different-load cooperative systems were discussed as well as optimizations of relative rigidity for same-load cooperative systems which greatly influence structural characteristics. The general situation and several structural measurements of several cooperative bridges were demonstrated. This information can assist engineers in developing their concepts in cooperative systems and can lead to more efficient and economical cooperative bridges.

    . Adotar a perspectiva cultural indígena para entender e esclarecer suas regras efetivas de uso e manejo dos recursos naturais pode representar o ponto de partida para desenvolver e implementar planos de manejo ecologicamente eficazes e socialmente benéficos. Redirecionar a disponibilidade ecológica global a pagar na direção dos povos indígenas representaria uma contribuição nesta direção.Nature conservation policies in different countries are increasingly linked to global ecological decision making. Examples of such linkages abound, and range from priorities and policy objectives defined in international forums and institutions to the action of global environmentally concerned NGOs, to global environmental and sustainable development funds and programmes, and new economic opportunities represented by emerging markets for global ecological services and environmental commodities. These policies often clash with the needs and rights of different populations, since the implementation of man-excluding protected areas is given priority over other models of biodiversity conservation and sustainable use. Brazil is no exception to this rule: today, nature conservation policies are entering in direct conflict with policies preserving indigenous people’s rights to cultural difference. This is happening at different levels, and in several different local contexts, from the Atlantic to the Amazon and the Guyana Shield regions. Global policy priorities and funding can contribute to explain these conflicts, as the global ecological link contributes to redefine national and local political relations. The case of Mount Roraima National Park, overlapping with the Raposa-Serra do Sol Indigenous Land, illustrates how conservation policies based on man exclusion, such as National Parks, conceived and implemented in a top-down fashion, stimulate pre-existing political and land rights conflicts. Approached through a different angle, this case also indicates a possible way to viable

    1989-01-01

    A converter for converting a low voltage direct current power source to a higher voltage, high frequency alternating current output for use in an electrical system where it is desired to use low weight cables and other circuit elements. The converter has a first stage series resonant (Schwarz) converter which converts the direct current power source to an alternating current by means of switching elements that are operated by a variable frequency voltage regulator, a transformer to step up the voltage of the alternating current, and a rectifier bridge to convert the alternating current to a direct current first stage output. The converter further has a second stage series resonant (Schwarz) converter which is connected in series to the first stage converter to receive its direct current output and convert it to a second stage high frequency alternating current output by means of switching elements that are operated by a fixed frequency oscillator. The voltage of the second stage output is controlled at a relatively constant value by controlling the first stage output voltage, which is accomplished by controlling the frequency of the first stage variable frequency voltage controller in response to second stage voltage. Fault tolerance in the event of a load short circuit is provided by making the operation of the first stage variable frequency voltage controller responsive to first and second stage current limiting devices. The second stage output is connected to a rectifier bridge whose output is connected to the input of the second stage to provide good regulation of output voltage wave form at low system loads.

    All attempts of aeroelastic explanations for the torsional instability of suspension bridges have been somehow criticised and none of them is unanimously accepted by the scientific community. We suggest a new nonlinear model for a suspension bridge and we perform numerical experiments with the parameters corresponding to the collapsed Tacoma Narrows Bridge. We show that the thresholds of instability are in line with those observed the day of the collapse. Our analysis enables us to give a new explanation for the torsional instability, only based on the nonlinear behavior of the structure.

Its first person narrative well presents stories of Vietnamese Americans’ adhering to history and tradition from older generation to the young. It also reveals an inevitable impact from Americanization, upon which the author ponders over how Vietnamese Americans should properly construct a cultural identity for themselves through reflecting upon history and reality. It puts great emphasis on multicultural integration symbiosis instead of antagonism to eliminate conflicts between “the other” and “self” through probing deep into the main characters’ traumatic memory, culture and history, reproducing the typical themes of post-colonialism, orientalism, and cultural conflicts. It is hoped that adopting bicultural identities of Vietnamese Americans can help them face life optimistically and be self-confident to speak out unique voice in the new world.

    Full Text Available Teachers act as bridges for their students. Teachers link young individuals to the knowledge and traditions of society. Through their professional practice and dedication, they help students develop the skills to succeed in school and in the world. In their classes, teachers help students relate to each other across cultures, which is crucial to the development and vitality of civil society in a changing world. Dedicated teachers are bridges reaching out to exceptional students or to underappreciated subjects. Visionary teachers develop innovative approaches that offer hope of a brighter future for everyone. The articles in this issue of Brock Education all highlight different ways in which educators are bridges to a better tomorrow.

As compared to white, Hurston considers black complexion as a beauty of difference. Black original ecological culture, which is defined as non-mainstream grassroots culture, is not only the strategy of the black’s survival but also the mark of Afro-American’s cultural identity, and the essential element of American culture. Black and white, black culture and white culture should keep the benign interaction between the racial groups and ethnic culture blending while maintaining individual characteristics. In the text Hurston makes a closer examina-tion of black men’s gender discrimination against black women, and advocates the equality inside the ethnic com-munity and the complementary harmony between the two genders. All of these open an effective channel for Af-ro-American women writers to appeal for gender, race and culture.

The formation of a stable ice arch prevents the further flow of sea ice into warmer oceans, and therefore plays an important role in the regulation of the local climate and ecology and to an extent, the mass balance of Arctic ice. While ice bridges are a seasonal phenomenon in many parts of the Canadian Archipelago, the process of their formation and breakup is poorly understood. Using thin-layer theory along with dynamic sea ice models widely used in climate modeling, we develop a reduced-order description of wind-driven ice bridge formation in long, narrow straits. Our theory predicts a critical static condition for arrested flow that involves the ice properties (thickness and compactness), the geometry of the channel, and the magnitude of the wind stress. Further, we show that in a channel of varying shape and under a constant wind stress, a spatially uniform ice field evolves towards a steady state with discontinuities in its properties, consistent with observed mechanisms of ice bridge formation. The reduced-order model thus provides a predictive tool for the flow and stoppage of sea ice in straits.

  19. The Higgs Bridge

    2013-01-01

    The particle recently discovered at the Large Hadron Collider near Geneva is almost certainly a Higgs boson, the long-sought completion of the Standard Model of particle physics. But this discovery, an achievement by more than six thousand scientists (including students), is actually much more than a mere capstone of the Standard Model. It instead represents a bridge from the Standard Model to exciting discoveries of the future, at higher energies or in other experiments, and to the properties of matter at very low temperatures. The mere existence of a particle with zero spin implies a need for new physics, with the most likely candidate being supersymmetry, which requires that every known particle has a superpartner yet to be discovered. And phenomena similar to the Higgs are seen in superconducting metals and superfluid gases at low temperatures, which extend down to a millionth or even a billionth of a degree Kelvin. So the discovery of a Higgs boson has a central place in our attempts both to achieve a tr...

  20. Mineral bridges in nacre revisited

    CERN Document Server

    Checa, Antonio G; Willinger, Marc-Georg

    2012-01-01

    We confirm with high-resolution techniques the existence of mineral bridges between superposed nacre tablets. In the towered nacre of both gastropods and the cephalopod Nautilus there are large bridges aligned along the tower axes, corresponding to gaps (150-200 nm) in the interlamellar membranes. Gaps are produced by the interaction of the nascent tablets with a surface membrane that covers the nacre compartment. In the terraced nacre of bivalves bridges associated with elongated gaps in the interlamellar membrane (> 100 nm) have mainly been found at or close to the edges of superposed parental tablets. To explain this placement, we hypothesize that the interlamellar membrane breaks due to differences in osmotic pressure across it when the interlamellar space below becomes reduced at an advanced stage of calcification. In no cases are the minor connections between superimposed tablets (< 60 nm), earlier reported to be mineral bridges, found to be such.

In fact, they achieve a lot and get many prizes like"The Beautiful Village". Founding a historical and cultural village and developing folk custom and ecological tourism are mutually improved. Founding a historical and cultural village encourages the development of the folk custom and ecological tourism. At the same time, developing the folk custom and ecological tourism can also motivate the local traditional culture. A lot of traditional customs have been renewed with the development of tourism. The creation and development of the historical and cultural products make the local customs and culture preserved and inherited. It is significant for the development of the area.

    Full Text Available By precisely manipulating the expression of individual genetic elements thought to be important for ecological performance, reverse genetics has the potential to revolutionize plant ecology. However, untested concerns about possible side-effects of the transformation technique, caused by Agrobacterium infection and tissue culture, on plant performance have stymied research by requiring onerous sample sizes. We compare 5 independently transformed Nicotiana attenuata lines harboring empty vector control (EVC T-DNA lacking silencing information with isogenic wild types (WT, and measured a battery of ecologically relevant traits, known to be important in plant-herbivore interactions: phytohormones, secondary metabolites, growth and fitness parameters under stringent competitive conditions, and transcriptional regulation with microarrays. As a positive control, we included a line silenced in trypsin proteinase inhibitor gene (TPI expression, a potent anti-herbivore defense known to exact fitness costs in its expression, in the analysis. The experiment was conducted twice, with 10 and 20 biological replicates per genotype. For all parameters, we detected no difference between any EVC and WT lines, but could readily detect a fitness benefit of silencing TPI production. A statistical power analyses revealed that the minimum sample sizes required for detecting significant fitness differences between EVC and WT was 2-3 orders of magnitude larger than the 10 replicates required to detect a fitness effect of TPI silencing. We conclude that possible side-effects of transformation are far too low to obfuscate the study of ecologically relevant phenotypes.

    努力寻求真理.统揽科学、文化、伦理道德和精神文明对于预防药物滥用和成瘾康复有重要的意义.主要文明体系的和睦关系将带来更为有效的策略,以克服由于药物滥用问题蔓延导致的全球性危机.%During recent decades scientific progress and discoveries on the brain and behaviour have revolutionized our knowledge of substance abuse and its impact on human mind and mood. Parallel with these scientific developments, there have been extensive research studies on psychological and sociocultural aspects of human behaviour and environmental forces which contribute to the development of drug abuse and addiction. Likewise, cultural factors are implicated in the rise and development of addictive behaviour in people in different parts of the world. To develop an effective strategy to combat the global problem of illicit drug use and addiction, there is a need to have an integrated and unified vision which would encompass not only a scientific perspective, but also would include cultural, ethical and spiritual components of society. Drug abuse is a multidimensional problem. It can be the result of biological and genetic predisposition. It can also often be due to a learned behaviour as a result of societal influence, drug availability and cultural attitudes. Therefore any successful plan of action for prevention, treatment or rehabilitation of those affected by drug abuse or addiction should take into consideration the multidisciplinary aspects of such a program. Scientific progress is being made in unravelling the importance of molecular biology, brain imaging and the role of neurotransmitters in the development and extent of tolerance and dependence on drugs and the addiction process. Moreover, research in this area is elucidating the possible pathways of genetic effects and transmission of addictive traits to offspring in disorders such as alcoholism.

    2013-07-01

    Interactions between evolutionary psychologists and developmental systems theorists have been largely antagonistic. This is unfortunate because potential synergies between the two approaches remain unexplored. This article presents a method that may help to bridge the divide, and that has proven fruitful in biology: dynamic optimization. Dynamic optimization integrates developmental systems theorists' focus on dynamics and contingency with the 'design stance' of evolutionary psychology. It provides a theoretical framework as well as a set of tools for exploring the properties of developmental systems that natural selection might favor, given particular evolutionary ecologies. We also discuss limitations of the approach.

    The South Dakota Space Grant Consortium (SDSGC) was established March 1, 1991 by a NASA Capability Enhancement Grant. Since that time SDSGC has worked to provide earth and space science educational outreach to all students across South Dakota. South Dakota has nine tribes and five tribal colleges. This has presented a tremendous opportunity to develop sustainable equitable partnerships and collaborations. SDSGC believes strongly in developing programs and activities that highlight the balance of indigenous science and ways of knowing with current findings in contemporary science. This blending of science and culture creates a learning community where individuals, especially students, can gain confidence and pride in their unique skills and abilities. Universities are also witnessing the accomplishments and achievements of students who are able to experience a tribal college environment and then carry that experience to a college/university/workplace and significantly increase the learning achievement of all. The presentation will highlight current Tribal College partnerships with Sinte Gleska University and Oglala Lakota College amongst others. Programs and activities to be explained during the presentation include: Native Connections, Scientific Knowledge for Indian Learning and Leadership (SKILL), Bridges to Success Summer Research Program, Fire Ecology Summer Experience, and dual enrolled/college bridge programs. The presentation will also cover the current initiatives underway through NASA Workforce Development. These include: partnering program with the Annual He Sapa Wacipi, American Indian Space Days 2005, NASA research/internship programs and NASA Fellow Summit. An overview of recent American Indian student success will conclude the presentation.

    2000-12-01

    Ice jamming, known to cause high water levels at even moderate river flows, is described as both the main and least understood source of ice-related bridge damages. This paper describes a joint study by the New Brunswick Department of Transportation, the Department of the Environment, local governments, and the National Water Research Institute, designed to address problems associated with the interaction of ice jams and bridges. The study consists of collecting information at each of four sites in New Brunswick including: historical data on ice jam locations, causes, and water levels; channel bathymetry, width and slope within each study centred at the respective bridge; and documentation of ice conditions throughout the ice season, including measurement of ice cover thickness, observation of breakup mechanisms, times, causes, characteristics and possible impacts of ice jam release. Data analysis will include determination of high stages due to ice jams or surges caused by upstream ice jam releases, scour potential of surges, and quantification of the structure's capacity to restrain ice movement and to cause jams. The principal objective of the study is to advance beyond empiricism and to develop rational design criteria for bridges by anticipating the effects of climate changes and by incorporating local meteorological and hydrometric records into bridge design for added safety.

    Teschke, Omar; Soares, David Mendez; Gomes, Whyllerson Evaristo; Valente Filho, Juracyr Ferraz

    2016-01-01

    The interaction of liquid with electric fields is investigated in a configuration where up to 13 kV are applied between electrodes resulting in a 106 V/m electric field in the capillaries and where there is the formation of a free-standing fluid bridge in the interelectrode gap. The Mott-Gurney equation was fitted to the measured ionization current vs applied voltage curve which indicates that the ionization rate at the high-voltage anode electrode dimethylsulfoxide (DMSO) interface and space charging in the interelectrode gap determine the floating liquid bridge current for a given cathode-to-anode voltage. Space charge effects were measured in the cathode becker and also at the liquid bridge since the ionized charges at the anode migrate to the bridge outer surface and decrease the interfacial tension from 43 mJ/m2 to 29 mJ/m2. Two distinct structural regions then form the bridge, a charged plastic (bulk modulus ˜100 MPa) conducting outer layer with a surface conductivity of ˜10-9 Ω-1, which shapes and supports the floating fluid structure, and an inner liquid cylinder, where DMSO molecules flow.

  1. A strange bridge by Leonardo

    CERN Document Server

    Huylebrouck, Dirk

    2013-01-01

    On folio 855 recto of the Codex Atlanticus, Leonardo da Vinci drew three 'easily movable' bridges, but one of them is enigmatic: all 'replicas' in Leonardo museums and exhibitions come as a surprise, to say the least, to any engineer or architect whose attention is drawn to it. This is the case for models in Amboise (France), Chicago and Portland (USA), Florence (Italy) and for the one of the traveling exhibition by the Australian company 'Grande Exhibitions' that already visited 40 major cities in the world. All 'replicas' of the bridge model attributed to Leonardo have pillars standing on the deck of the bridge, while the deck is suspended by cables attached on these pillars. At first sight this problem does not catch the attention of the observer, as the bridge seems to be a mixed form of a beam and a suspension bridge, but it was not overlooked by my colleague architect-engineer Dr. Laurens Luyten (Gent, Belgium). Yet, after a TV-interview in Brussels so much pressure was exerted by some of the museum col...

    The most pressing problems facing humanity today - over-population, energy shortages, climate change, soil erosion, species extinctions, the risk of epidemic disease, the threat of warfare that could destroy all the hard-won gains of civilization, and even the recent fibrillations of the stock market - are all ecological or have a large ecological component. in this volume philosophers turn their attention to understanding the science of ecology and its huge implications for the human project. To get the application of ecology to policy or other practical concerns right, humanity needs a clear and disinterested philosophical understanding of ecology which can help identify the practical lessons of science. Conversely, the urgent practical demands humanity faces today cannot help but direct scientific and philosophical investigation toward the basis of those ecological challenges that threaten human survival.

    Farrar, C.R.; Duffy, T.A.; Cornwell, P.J.; Doebling, S.W.

    1999-02-08

    This paper summarizes the various methods that have been used to excited bridge structures during dynamic testing. The excitation methods fall into the general categories of ambient excitation methods and measured-input excitation methods. During ambient excitation the input to the bridge is not directly measured. In contrast, as the category label implies, measured-input excitations are usually applied at a single location where the force input to the structure can be monitored. Issues associated with using these various types of measurements are discussed along with a general description of the various excitation methods.

    Full Text Available Cultural ecosystem services constitute a growing field of research that is characterized by an increasing number of publications from various academic disciplines. We conducted a semiquantitative review of publications explicitly dealing with cultural ecosystem services. Our aims were: (1 to provide an overview of the current state of research, (2 to classify the diversity of research approaches by identifying clusters of publications that address cultural ecosystem services in similar ways, and (3 to highlight some important challenges for the future of cultural ecosystem services research. We reviewed 107 publications and extracted 20 attributes describing their type and content, including methods, scales, drivers of change, and trade-offs between services. Using a cluster analysis on a subset of attributes we identified five groups of publications: Group 1, conceptual focus, deals with theoretical issues; Group 2, descriptive reviews, consists mostly of desktop studies; Group 3, localized outcomes, deals with case studies coming from different disciplines; Group 4, social and participatory, deals mainly with assessing preferences and perceptions; and Group 5, economic assessments, provides economic valuations. Emerging themes in cultural ecosystem services research relate to improving methods for cultural ecosystem services valuation, studying cultural ecosystem services in the context of ecosystem service bundles, and more clearly articulating policy implications. Based on our findings, we conclude that: (1 cultural ecosystem services are well placed as a tool to bridge gaps between different academic disciplines and research communities, (2 capitalizing on the societal relevance of cultural ecosystem services could help address real-world problems, and (3 cultural ecosystem services have the potential to foster new conceptual links between alternative logics relating to a variety of social and ecological issues.

  15. What is dental ecology?

    Cuozzo, Frank P; Sauther, Michelle L

    2012-06-01

    Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context.

    Winslow, Wendy Wilkins; Honein, Gladys

    2007-03-01

    Health care services in the United Arab Emirates have developed rapidly in the last 30 years fueled by oil revenues. These services have been planned and provided predominantly by non-nationals, with mixed success. The authors identify aspects of the health care system and the sociocultural environment that create both barriers and bridges to holistic health for Emirati women. Barriers include early/consanguineous marriage, frequent childbearing, polygamy, and care that is lacking in competence and cultural sensitivity. Bridges include Islam, folk medicine, cultural traditions, and the opportunity to travel abroad for health care. Maids are seen as both a barrier and bridge at different times. Recommendations for future improvements include listening to Emirati women and providing more gender-appropriate, holistic, and culturally congruent programs.

    Directory of Open Access Journals (Sweden)

    Luca Caneparo

    Full Text Available The developing zebrafish embryo has been the subject of many studies of regional patterning, stereotypical cell movements and changes in cell shape. To better study the morphological features of cells during gastrulation, we generated mosaic embryos expressing membrane attached Dendra2 to highlight cellular boundaries. We find that intercellular bridges join a significant fraction of epiblast cells in the zebrafish embryo, reaching several cell diameters in length and spanning across different regions of the developing embryos. These intercellular bridges are distinct from the cellular protrusions previously reported as extending from hypoblast cells (1-2 cellular diameters in length or epiblast cells (which were shorter. Most of the intercellular bridges were formed at pre-gastrula stages by the daughters of a dividing cell maintaining a membrane tether as they move apart after mitosis. These intercellular bridges persist during gastrulation and can mediate the transfer of proteins between distant cells. These findings reveal a surprising feature of the cellular landscape in zebrafish embryos and open new possibilities for cell-cell communication during gastrulation, with implications for modeling, cellular mechanics, and morphogenetic signaling.

    2010-09-01

    Ecological systems modelling based on the unified biophysical measure of cosmic emergy in terms of embodied cosmic exergy is illustrated in this paper with ecological accounting, simulation and scenario analysis, by a case study for the regional socio-economic ecosystem associated with the municipality of Beijing. An urbanized regional ecosystem model with eight subsystems of natural support, agriculture, urban production, population, finance, land area, potential environmental impact, and culture is representatively presented in exergy circuit language with 12 state variables governing by corresponding ecodynamic equations, and 60 flows and auxiliary variables. To characterize the regional socio-economy as an ecosystem, a series of ecological indicators based on cosmic emergy are devised. For a systematic ecological account, cosmic exergy transformities are provided for various dimensions including climate flows, natural resources, industrial products, cultural products, population with educational hierarchy, and environmental emissions. For the urban ecosystem of Beijing in the period from 1990 to 2005, ecological accounting is carried out and characterized in full details. Taking 2000 as the starting point, systems modelling is realized to predict the urban evolution in a one hundred time horizon. For systems regulation, scenario analyses with essential policy-making implications are made to illustrate the long term systems effects of the expected water diversion and rise in energy price.

  7. Neutral theory in community ecology

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    One of the central goals of community ecology is to understand the forces that maintain species diversity within communities. The traditional niche-assembly theory asserts that species live together in a community only when they differ from one another in resource uses. But this theory has some difficulties in explaining the diversity often observed in specie-rich communities such as tropical forests. As an alternative to the niche theory, Hubbell and other ecologists introduced a neutral model. Hubbell argues that the number of species in a community is controlled by species extinction and immigration or speciation of new species. Assuming that all individuals of all species in a trophically similar com-munity are ecologically equivalent, Hubbell's neutral theory predicts two important statistical distributions. One is the asymptotic log-series distribution for the metacommunities under point mutation speciation, and the other is the zero-sum multinomial distribution for both local communities under dispersal limitation and metacommunities under random fission speciation. Unlike the niche-assembly theory, the neutral theory takes similarity in species and individuals as a starting point for investigating species diversity. Based on the fundamental processes of birth, death, dispersal and spe-ciation, the neutral theory provided the first mechanistic explanation of species abundance distribution commonly observed in natural communities. Since the publication of the neutral theory, there has been much discussion about it, pro and con. In this paper, we summarize recent progress in the assumption, prediction and speciation mode of the neutral theory, including progress in the theory itself, tests about the assumption of the theory, prediction and speciation mode at the metacommunity level. We also suggest that the most important task in the future is to bridge the niche-assembly theory and the neutral theory, and to add species differences to the neutral theory and

    Full Text Available The use of a participant survey, administered at the outset of an online course, can provide information useful in the management of the learning environment and in its subsequent redesign. Such information can clarify participants’ prior experience, expectations, and demographics. But the very act of enquiring about the learner also signals the instructor’s social presence, relational interest, and desire to enter into an authentic dialogue. This study examines the use of participant surveys in online management courses. The first section discusses the informational bridges that this instrument provides. The second section considers survey responses to open-ended questions dealing with student sentiments. This analysis suggests that the survey plays a valuable part in accentuating social presence and in initiating relational bridges with participants.

    Anthropology research approach of meteorological disasters is an important method of disaster anthropology research and is developed on the basis of meteorological disasters�research approach of“organiza-tion-system” and “politics-society”, which is a new-type research approach using cultural response as main line. The anthropology research contents of meteorological disasters can be summarized as the three aspects:cultural interpretation of meteorological disaster typology, meteorological disaster emergency, cultural response and adaptation in disaster relief, cultural recovery, transition and construction in the process of meteorological disaster recovery, and reconstruction. Anthropology research of meteorological disasters should use a combination of methods such as tracking survey, field investigation and disaster ethnography. Carrying out eco-logical civilization construction from the perspective of addressing climate change needs to survey ecological civ-ilization under the background of addressing climate change, introduce ecological civilization on the basis of solving the climate crisis, build ecological civilization on the main line of cultural response, and develop eco-logical civilization in the interaction of theory and practice.%气象灾害的人类学研究途径是灾害人类学研究的一个重要方法,是在气象灾害的“组织-制度”研究途径和“政治-社会”研究途径基础上发展起来的以文化回应为主线的新型气象灾害研究途径。结合我国气象灾害的实际,可以将气象灾害的人类学研究内容归纳为三个方面:气象灾害类型学的文化诠释,气象灾害应急、救灾中的文化应对和适应,气象灾害恢复、重建过程中的文化恢复、变迁和构建。气象灾害的人类学研究应综合运用追踪调查、田野调查和灾害民族志等方法。在应对气候变化视角下进行生态文明建设,要在应对气候变化的背景下

    Bridges and routers are used to interconnect Local Area Networks (LANs). The performance of these devices is important since they can become bottlenecks in large multi-segment networks. Performance metrics and test methodology for bridges and routers were not standardized. Performance data reported by vendors is not applicable to the actual scenarios encountered in an operational network. However, vendor-provided data can be used to calibrate models of bridges and routers that, along with other models, yield performance data for a network. Several tools are available for modeling bridges and routers - Network II.5 was used. The results of the analysis of some bridges and routers are presented.

    Prine, David W.

    1995-05-01

    The US has 542,000 bridges that consume billions of dollars per year in construction, rehabilitation, and maintenance funds and which are the lifelines of US commerce. The 1992 ISTEA (Intermodal Surface Transportation Efficiency Act) mandates the implementation of a quantitative computerized bridge management system by 1996. A prime need of such a system are quantitative bridge inspection methods to feed accurate reliable condition information to the huge database of bridges. Nondestructive evaluation (NDE) will fill a critical need in the implementation of effective bridge management. However, many serious barriers exist to the widespread routine application of this technology to bridges.

    Colquitt, D. J.; Movchan, N. V.; Movchan, A. B.

    2016-10-01

    A new class of multi-scale structures, referred to as `parabolic metamaterials' is introduced and studied in this paper. For an elastic two-dimensional triangular lattice, we identify dynamic regimes, which corresponds to so-called `Dirac Bridges' on the dispersion surfaces. Such regimes lead to a highly localised and focussed unidirectional beam when the lattice is excited. We also show that the flexural rigidities of elastic ligaments are essential in establishing the `parabolic metamaterial' regimes.

    Human societies, and their well-being, depend to a significant extent on the state of the ecosystems that surround them. These ecosystems are changing rapidly usually in response to anthropogenic changes in the environment. To determine the likely impact of environmental change on ecosystems and the best ways to manage them, it would be desirable to be able to predict their future states. We present a proposal to develop the paradigm of predictive systems ecology, explicitly to understand and predict the properties and behaviour of ecological systems. We discuss the necessary and desirable features of predictive systems ecology models. There are places where predictive systems ecology is already being practised and we summarize a range of terrestrial and marine examples. Significant challenges remain but we suggest that ecology would benefit both as a scientific discipline and increase its impact in society if it were to embrace the need to become more predictive.

    A new type of cochleate, able to microencapsulate water-soluble cationic drugs or peptides into its inter-lipid bi-layer space, was formed through interaction between negatively charged lipids and drugs or peptides acting as the inter-bi-layer bridges instead of multi-cationic metal ions. This new type of cochleate opened up to form large liposomes when treated with EDTA, suggesting that cationic organic molecules can be extracted from these cochleates in a way similar to multivalent metal ions from metal ion-bridged cochleates. Cochleates can be produced in sub-micron size using a method known as "hydrogel isolated cochleation" or simply by increasing the ratio of multivalent cationic peptides over negatively charged liposomes. When nanometer-sized cochleates and liposomes containing the same fluorescent labeled lipid component were incubated with human fibroblasts cells under identical conditions, cells exposed to cochleates showed bright fluorescent cell surfaces, whereas those incubated with liposomes did not. This result suggests that cochleates' edges made them fuse with the cell surfaces as compared to edge free liposomes. This mechanism of cochleates' fusion with cell membrane was supported by a bactericidal activity assay using tobramycin cochleates, which act by inhibiting intracellular ribosomes. Tobramycin bridged cochleates in nanometer size showed improved antibacterial activity than the drug's solution.

  20. Enacting a social ecology: radically embodied intersubjectivity.

    Science.gov (United States)

    McGann, Marek

    2014-01-01

    Embodied approaches to cognitive science frequently describe the mind as "world-involving," indicating complementary and interdependent relationships between an agent and its environment. The precise nature of the environment is frequently left ill-described, however, and provides a challenge for such approaches, particularly, it is noted here, for the enactive approach which emphasizes this complementarity in quite radical terms. This paper argues that enactivists should work to find common cause with a dynamic form of ecological psychology, a theoretical perspective that provides the most explicit theory of the psychological environment currently extant. In doing so, the intersubjective, cultural nature of the ecology of human psychology is explored, with the challenges this poses for both enactivist and ecological approaches outlined. The theory of behavior settings (Barker, 1968; Schoggen, 1989) is used to present a framework for resolving some of these challenges. Drawing these various strands together an outline of a radical embodied account of intersubjectivity and social activity is presented.

    Donald, Jason E; Kulp, Daniel W; DeGrado, William F

    2011-03-01

    Salt bridges occur frequently in proteins, providing conformational specificity and contributing to molecular recognition and catalysis. We present a comprehensive analysis of these interactions in protein structures by surveying a large database of protein structures. Salt bridges between Asp or Glu and His, Arg, or Lys display extremely well-defined geometric preferences. Several previously observed preferences are confirmed, and others that were previously unrecognized are discovered. Salt bridges are explored for their preferences for different separations in sequence and in space, geometric preferences within proteins and at protein-protein interfaces, co-operativity in networked salt bridges, inclusion within metal-binding sites, preference for acidic electrons, apparent conformational side chain entropy reduction on formation, and degree of burial. Salt bridges occur far more frequently between residues at close than distant sequence separations, but, at close distances, there remain strong preferences for salt bridges at specific separations. Specific types of complex salt bridges, involving three or more members, are also discovered. As we observe a strong relationship between the propensity to form a salt bridge and the placement of salt-bridging residues in protein sequences, we discuss the role that salt bridges might play in kinetically influencing protein folding and thermodynamically stabilizing the native conformation. We also develop a quantitative method to select appropriate crystal structure resolution and B-factor cutoffs. Detailed knowledge of these geometric and sequence dependences should aid de novo design and prediction algorithms.

    Emission and redistribution of dust due to wind erosion in drylands drives major biogeochemical dynamics and provides important aeolian environmental connectivity at scales from individual plants up to the global scale. Yet, perhaps because most relevant research on aeolian processes has been presented in a geosciences rather than ecological context, most ecological studies do not explicitly consider dust-driven processes. To bridge this disciplinary gap, we provide a general overview of the ecological importance of dust, examine complex interactions between wind erosion and ecosystem dynamics from the plant-interspace scale to regional and global scales, and highlight specific examples of how disturbance affects these interactions and their consequences. Changes in climate and intensification of land use will both likely lead to increased dust production. To address these challenges, environmental scientists, land managers and policy makers need to more explicitly consider dust in resource management decisions.

    The success of research in integrated environmental and natural resource management relies on the participation and involvement of different disciplines and stakeholders. This can be difficult to achieve in practice because many initiatives fail to address the underlying social processes required for successful engagement and social learning. We used an action research approach to support a research-based group with a range of disciplinary and stakeholder expertise to critically reflect on their engagement practice and identify lessons around how to collaborate more effectively. This approach is provided here as a guide that can be used to support reflective research practice for engagement in other integration-based initiatives. This paper is set in the context of an integrated wildlife management research case study in New Zealand. We illustrate how multi-, inter- and trans-disciplinary approaches can provide a framework for considering the different conversations that need to occur in an integrated research program. We then outline rubrics that list the criteria required in inter- and trans-disciplinary collaborations, along with examples of effective engagement processes that directly support integration through such efforts. Finally, we discuss the implications of these experiences for other researchers and managers seeking to improve engagement and collaboration in integrated science, management and policy initiatives. Our experiences reaffirm the need for those involved in integrative initiatives to attend to the processes of engagement in both formal and informal settings, to provide opportunities for critical reflective practice, and to look for measures of success that acknowledge the importance of effective social process.

    Disease and community ecology share conceptual and theoretical lineages, and there has been a resurgence of interest in strengthening links between these fields. Building on recent syntheses focused on the effects of host community composition on single pathogen systems, we examine pathogen (microparasite) communities using a stochastic metacommunity model as a starting point to bridge community and disease ecology perspectives. Such models incorporate the effects of core community processes, such as ecological drift, selection and dispersal, but have not been extended to incorporate host-pathogen interactions, such as immunosuppression or synergistic mortality, that are central to disease ecology. We use a two-pathogen susceptible-infected (SI) model to fill these gaps in the metacommunity approach; however, SI models can be intractable for examining species-diverse, spatially structured systems. By placing disease into a framework developed for community ecology, our synthesis highlights areas ripe for progress, including a theoretical framework that incorporates host dynamics, spatial structuring and evolutionary processes, as well as the data needed to test the predictions of such a model. Our synthesis points the way for this framework and demonstrates that a deeper understanding of pathogen community dynamics will emerge from approaches working at the interface of disease and community ecology.

    Parasitism as one of the life modes is a general biological phenomenon and is a characteristic of all viruses, many taxa of bacteria, fungi, protists, metaphytes, and metazoans. Zooparasitology is focused on studies of parasitic animals, particularly, on their taxonomy, anatomy, life cycles, host-parasite relations, biocoenotic connections, and evolution. Ecological parasitology is a component of ecology, as the scientific study of the relation of living organisms with each other and their surroundings. In the present paper, critical analysis of the problems, main postulates, and terminology of the modern ecological parasitology is given.

  14. The Long-Term Effective Mechanism of Rural Poverty Alleviation in China from the Perspective of Ecological Management

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Based on the ecological environmental situation of poverty-stricken areas in China and the domestic and foreign research results,the long-term effective mechanism of sustainable poverty alleviation in China is established(the ideological premise is ecological culture,the material base is ecological economy and the basic guarantee is ecological system) from the perspective of ecological management.To be specific,ecological culture,the ideological premise of rural sustainable poverty alleviation in China,includes two aspects:the first one is upholding the Marxism,passing on the Chinese traditional ecological wisdom and fostering ecological consciousness;the second one is mirroring the thought of western modern ecological ethics,emphasizing ecological criticism and redoubling the ecological education.As for ecological economy,the material guarantee for sustainable poverty alleviation in Chinese rural poverty-stricken areas,also contents two aspects.The first one is promoting the way of "clean production" and developing ecological industry;the second one is building ecological concept of consumption and establishing the ecological lifestyle.In addition,ecological system,the basic guarantee of sustainable poverty alleviation in Chinese rural poverty-stricken areas,covers three terms.The first one is implementing the ecological policies and stipulating ecological plan;the second one is establishing perfect ecological legislation and ecological system and intensifying their implementation;the third one is enforcing ecological management in the process of sustainable poverty alleviation.Through the establishment of the above mechanism,we look forward to realizing sustainability of economic development and poverty alleviation effects in the process of poverty alleviation in Chinese rural areas,as well as ecological management of the poverty-stricken areas.

    The study of secession generally stresses the causal influence of cultural identities, political preferences, or ecological factors. Whereas these different views are often considered to be mutually exclusive, this paper proposes a two-stage model in which they are complementary. We posit...... that cultural identities matter for explaining secessionism, but not because of primordial attachments. Rather, religious and linguistic groups matter because their members are imbued with cultural legacies that lead to distinct political preferences – in this case preferences over welfare statism. Further......, ecological constraints such as geography and topography affect social interaction with like-minded individuals. On the basis of both these political preferences and ecological constraints, individuals then make rational choices about the desirability of secession. Instrumental considerations are therefore...

    Considering the construction features of prestressed concrete bridge, the comprehensive evaluation method about the bridge damage conditions are studied. Particular attentions are paid on establishing a multi-level evaluation model for damaged prestressed concrete bridge, and the evaluation indices of the model as well as the rating standards are defined in the model. A normal relative function about the evaluation indices of each element is developed to calculate the relative degree, and for each element which is no sub-level elements. When evaluating the elements in sub-item level or index level of the model, the weights of elements that are pertained to one element are adopted, taking account of their deterioration degree. At the same time, the dam-age conditions of bridge are characterized by relative degree, element evaluation scale and structural technology mark of bridge ,so it agrees with Code for Maintenance of Highway Bridges and Culvers.

  20. Marine Ecological Environment Management Based on Ecological Compensation Mechanisms

    Directory of Open Access Journals (Sweden)

    Qunzhen Qu

    2016-12-01

    Full Text Available The level of marine environmental management is a key factor in the successful implementation of marine power strategies. The improvement in management levels of marine environments requires innovation in marine management. In other words, the transformation of marine environmental management into marine ecological environment management must be done in order to achieve sustainable development of the marine economy. As an environmental economic policy that combines both administrative and market measures, ecological compensation mechanisms have significant advantages in marine ecological environment management. Based on the study of the current development of ecological compensation mechanisms in China, through the analysis of the connotation of marine ecological civilization, existing marine ecological protection practices and marine environmental management methods, this paper posits that the current marine ecological environment management in China should be established on the basis of ecological compensation mechanisms. At present, a lack of laws and regulations for overall marine ecological environment management is the key factor restricting the practice of marine ecological environment management. Therefore, it is necessary to explore the current path of marine ecological environment management in China from the perspective of the construction of legal system of ecological compensation law, the establishment of ecological compensation fees, ecological taxes and ecological compensation fund systems, and the clear status for a marine ecological management and supervision body.

    The chapter reviews a classical Indian model of consciousness found in the Abhidhamma, a collection of seven treatises in the Pali Canon Tipitaka. The model was based on observations made during advanced vipassana practice, a first-person method taught by the Buddha. The climax of the model consists in the elucidation of 24 'Bridging Relations' causally linking the stream of consciousness, its contents and associated physical events. Review of such a model based on a specialized first-person technique could prove to be a resource of useful ideas providing directions for further research.

    Reflecting on the suicide of a close friend, this essay explores what comprises, and inspires a will to live, and how those in Family Medicine can address suicide risk even in the face of debilitating or terminal illness. Research indicates that the will to live is a measurable indicator of general well-being, distinct from depression, and an important predictor of a person's motivation to "hold on to life". As such, understanding what is at the heart of a desire to live should alter clinical practice. This essay offers ideas for ways in which to create bridges for patients that could help sustain life.

    From earlier ecological studies it has become apparent that simple univariate or bivariate statistics are often inappropriate, and that multivariate statistical analyses must be applied. Despite several difficulties arising from the application of multivariate methods, community ecology has acquired a mathematical framework, with three consequences: it can develop as an exact science; it can be applied operationally as a computer-assisted science to the solution of environmental problems; and it can exchange information with other disciplines using the language of mathematics.

    2017-01-01

    This paper presents the results of a consensus-driven process identifying 50 priority research questions for historical ecology obtained through crowdsourcing, literature reviews, and in-person workshopping. A deliberative approach was designed to maximize discussion and debate with defined outcomes. Two in-person workshops (in Sweden and Canada) over the course of two years and online discussions were peer facilitated to define specific key questions for historical ecology from anthropological and archaeological perspectives. The aim of this research is to showcase the variety of questions that reflect the broad scope for historical-ecological research trajectories across scientific disciplines. Historical ecology encompasses research concerned with decadal, centennial, and millennial human-environmental interactions, and the consequences that those relationships have in the formation of contemporary landscapes. Six interrelated themes arose from our consensus-building workshop model: (1) climate and environmental change and variability; (2) multi-scalar, multi-disciplinary; (3) biodiversity and community ecology; (4) resource and environmental management and governance; (5) methods and applications; and (6) communication and policy. The 50 questions represented by these themes highlight meaningful trends in historical ecology that distill the field down to three explicit findings. First, historical ecology is fundamentally an applied research program. Second, this program seeks to understand long-term human-environment interactions with a focus on avoiding, mitigating, and reversing adverse ecological effects. Third, historical ecology is part of convergent trends toward transdisciplinary research science, which erodes scientific boundaries between the cultural and natural. PMID:28235093

  3. Review of Energy Harvesters Utilizing Bridge Vibrations

    2016-01-01

    Full Text Available For health monitoring of bridges, wireless acceleration sensor nodes (WASNs are normally used. In bridge environment, several forms of energy are available for operating WASNs that include wind, solar, acoustic, and vibration energy. However, only bridge vibration has the tendency to be utilized for embedded WASNs application in bridge structures. This paper reports on the recent advancements in the area of vibration energy harvesters (VEHs utilizing bridge oscillations. The bridge vibration is narrowband (1 to 40 Hz with low acceleration levels (0.01 to 3.8 g. For utilization of bridge vibration, electromagnetic based vibration energy harvesters (EM-VEHs and piezoelectric based vibration energy harvesters (PE-VEHs have been developed. The power generation of the reported EM-VEHs is in the range from 0.7 to 1450000 μW. However, the power production by the developed PE-VEHs ranges from 0.6 to 7700 μW. The overall size of most of the bridge VEHs is quite comparable and is in mesoscale. The resonant frequencies of EM-VEHs are on the lower side (0.13 to 27 Hz in comparison to PE-VEHs (1 to 120 Hz. The power densities reported for these bridge VEHs range from 0.01 to 9539.5 μW/cm3 and are quite enough to operate most of the commercial WASNs.

  4. CONDITION RATING SYSTEM FOR THAILAND'S CONCRETE BRIDGES

    Directory of Open Access Journals (Sweden)

    2010-06-01

    Full Text Available The Bridge Management System is designed to maximise use of available data and determine the optimal strategy to perform necessary improvements to bridges in the most cost-effective manner. This paper provides a condition rating system to meet the requirements of Thailand’s Department of Highways (DOH. A rating system to assess the existing condition of bridges is proposed. Segmental inspection is developed to execute efficient element-level evaluations and collect data that demonstrate deterioration patterns in bridge elements. The paper also describes inspection procedures for field survey execution, which enables observed distresses at the level of sub-elements or members to be allocated. Recommendations from bridge experts reveal that the proposed rating system is robust, implementable in actual practice, and suitable for efficient application in evaluating the nation’s concrete highway bridges. Although the bridge condition rating was developed in response to the specific characteristics of Thailand’s bridges, the proposed methodology can easily be extended to other bridge agencies.

    2015-04-01

    This paper discusses a data management infrastructure framework for bridge monitoring applications. As sensor technologies mature and become economically affordable, their deployment for bridge monitoring will continue to grow. Data management becomes a critical issue not only for storing the sensor data but also for integrating with the bridge model to support other functions, such as management, maintenance and inspection. The focus of this study is on the effective data management of bridge information and sensor data, which is crucial to structural health monitoring and life cycle management of bridge structures. We review the state-of-the-art of bridge information modeling and sensor data management, and propose a data management framework for bridge monitoring based on NoSQL database technologies that have been shown useful in handling high volume, time-series data and to flexibly deal with unstructured data schema. Specifically, Apache Cassandra and Mongo DB are deployed for the prototype implementation of the framework. This paper describes the database design for an XML-based Bridge Information Modeling (BrIM) schema, and the representation of sensor data using Sensor Model Language (SensorML). The proposed prototype data management framework is validated using data collected from the Yeongjong Bridge in Incheon, Korea.

    Colleges and universities are increasingly recognizing the need to expand suicide-prevention efforts beyond the standard, clinical-intervention paradigm of suicide prevention, which relies on referral to, and treatment by, mental health services. These services frequently struggle, however, to provide effective, comprehensive care. After reviewing findings that support the need to adopt a broader, problem-focused paradigm, the article provides a framework for bridging this paradigm with the clinical-intervention approach and for conceptualizing a full continuum of preventive interventions. For each level of intervention (ranging from the individual to the ecological), we describe the goals and methods used, and provide examples to illustrate the role of psychiatrists and other campus mental health providers in the collaborative partnerships that must form to support a comprehensive, campus-wide suicide-prevention strategy.

    1999-12-01

    The Bridge of Mandolin County is a case designed to teach the general chemistry principles of molar mass, ions and aqueous reactions, solubility rules, and inorganic nomenclature. Through the instructor-facilitated class discussion, students consider the options before the Mandolin Town Council regarding deicing the newly constructed bridge connecting Mandolin with a large nearby city. The students must decipher contradictory claims made on behalf of sodium chloride, the traditional deicer, and calcium magnesium acetate, a new environmentally friendly deicer, to arrive at the most cost-effective and environmentally appropriate deicing product. As they work through the analysis they raise questions that can be addressed in a laboratory setting. Four optional role-playing experiments are included, which can be used by the students to gather information helpful to resolution of the case. The case is intended to be used over two class periods, with a laboratory period in between, though suggestions for other models are provided. Laboratory procedures include an EDTA titration for Ca2+ and Mg2+, a gravimetric analysis, a qualitative examination of ions and solubility, an introduction to freezing point depression and measurement, and an experimental design activity. This case can also successfully be used without alteration in non-majors chemistry or environmental chemistry courses, or upper-level analytical or environmental chemistry courses.

    2000-06-01

    Knowledge of the integrity of in-service structures on a continuous time basis is an ultimate objective for owners and maintenance authorities. The development of a life extension and/or replacement strategy for highway structures is a crucial point in an effective bridge management system. A key component of such a bridge management system is a means of surveillance techniques and determining the condition of an existing structure within the normative and budgetary constraints. Recent advances in sensing technologies and material/structure damage characterization combined with current developments in computations and communications have resulted in a significant interest in developing diagnostic technologies for monitoring the integrity of and for the detection of damages of structures. To identify anomalies and deterioration processes, it is essential to understand the relationships between the signal measurements and the real occurred phenomena. Therefore, the comparison of measured and calculated data in order to tune and validate the mechanical and numerical model assumptions is an integral part of any system analysis. Finally, the interpreted results of all measurements should be the basis for the condition assessment and the safety evaluation of a structure to facilitate replacement and repair decisions.

    Full Text Available Halophilic proteins have greater abundance of acidic over basic and very low bulky hydrophobic residues. Classical electrostatic stabilization was suggested as the key determinant for halophilic adaptation of protein. However, contribution of specific electrostatic interactions (i.e. salt-bridges to overall stability of halophilic proteins is yet to be understood. To understand this, we use Adaptive-Poison-Boltzmann-Solver Methods along with our home-built automation to workout net as well as associated component energy terms such as desolvation energy, bridge energy and background energy for 275 salt-bridges from 20 extremely halophilic proteins. We then perform extensive statistical analysis on general and energetic attributes on these salt-bridges. On average, 8 salt-bridges per 150 residues protein were observed which is almost twice than earlier report. Overall contributions of salt-bridges are -3.0 kcal mol-1. Majority (78% of salt-bridges in our dataset are stable and conserved in nature. Although, average contributions of component energy terms are equal, their individual details vary greatly from one another indicating their sensitivity to local micro-environment. Notably, 35% of salt-bridges in our database are buried and stable. Greater desolvation penalty of these buried salt-bridges are counteracted by stable network salt-bridges apart from favorable equal contributions of bridge and background terms. Recruitment of extensive network salt-bridges (46% with a net contribution of -5.0 kcal mol-1 per salt-bridge, seems to be a halophilic design wherein favorable average contribution of background term (-10 kcal mol-1 exceeds than that of bridge term (-7 kcal mol-1. Interiors of proteins from halophiles are seen to possess relatively higher abundance of charge and polar side chains than that of mesophiles which seems to be satisfied by cooperative network salt-bridges.

    2012-11-01

    Despite the "awakening" to the importance of culture in psychology in America, international psychology has remained on the sidelines of psychological science. The author recounts her personal and professional experience in tandem with the stages of development in international/cross-cultural psychology. Based on her research in cross-cultural personality assessment, the author discusses the inadequacies of sole reliance on either the etic or the emic approach and points out the advantages of a combined emic-etic approach in bridging global and local human experiences in psychological science and practice. With the blurring of the boundaries between North American-European psychologies and psychology in the rest of the world, there is a need to mainstream culture in psychology's epistemological paradigm. Borrowing from the concept of gender mainstreaming that embraces both similarities and differences in promoting equal opportunities, the author discusses the parallel needs of acknowledging universals and specifics when mainstreaming culture in psychology. She calls for building a culturally informed universal knowledge base that should be incorporated in the psychology curriculum and textbooks.

  8. Beyond the Blue Marble: Artistic research on space and ecology

    2016-11-01

    This paper discusses the relation of space and ecology through examples of artistic research on the closed ecological system experiment Biosphere 2 and the history of space settlements. While the idea of artificial ecological systems in space dates back to the first visions of space exploration, the best known link between ecology and space is probably the Whole Earth photos of the Apollo program. Following recent reconceptualizations of Ecology beyond the nature-culture divide I argue that this popular icon of ecology and space by now has become a limitation to both space exploration and a new ecological understanding in the Anthropocene. By interpreting Biosphere 2 as a model of our world that is not limited to biological relations but also includes socio-political aspects, culture, economy and technology, my performative research supports the idea of "Ecology without Nature" as proposed by Timothy Morton and others. Furthermore, through an artistic exploration of the local history and legacy of 1970s' space settlement enthusiasm in the San Francisco Bay Area and its ties to the later digital frontier and Green Capitalism, the paper discusses the 1990s as a pivotal transformational period for space and ecology. While so-called "globalizations" have often been illustrated by the Whole Earth image, associated developments have essentially revealed vast dimensions of space and time that have unsettled our very concept of world and are characteristic issues of the Anthropocene. At the same time, this "end of the world" could be employed to relate the Anthropocene to space exploration and rethink ecology as a theoretical framework transcending planet Earth.

  9. Agri-environmental collaboratives as bridging organisations in landscape management.

    2015-09-15

    In recent years, landscape and its management has become a focus of policies and academic conceptualisation. Landscape is understood as a concept of interconnected natural and human systems. Its management must take into account the dynamic interdependencies and diverging interests of various stakeholders at different levels. Bridging organisations can provide an arena for trust-building, conflict resolution, learning and collaboration between relevant stakeholders. This paper draws on two strands of literature - landscape governance and co-management of social-ecological systems - to investigate the contributions of agri-environmental collaboratives (AEC) to sustainable landscape management. Based on data from 41 interviews with key informants and AEC members in Germany and the Netherlands, six fields of contributions were identified: policy implementation and service provision; coordination and mediation; awareness raising and behaviour change; care for 'everyday' landscapes; maintenance and protection of landscapes (including species and habitats); and income generation and economic benefits. Some of the contributions evolve around the specific role of AEC as bridging organisations, but other contributions such as economic benefits emerge beyond this analytical lens. The paper therefore emphasises holistic, bottom up assessment of AEC contributions and argues that governments should support such organisations through i) funding for facilitators and ii) funding for impact monitoring and data management.

  10. How did the spider cross the river? Behavioral adaptations for river-bridging webs in Caerostris darwini (Araneae: Araneidae.

    Directory of Open Access Journals (Sweden)

    Matjaž Gregorič

    Full Text Available BACKGROUND: Interspecific coevolution is well described, but we know significantly less about how multiple traits coevolve within a species, particularly between behavioral traits and biomechanical properties of animals' "extended phenotypes". In orb weaving spiders, coevolution of spider behavior with ecological and physical traits of their webs is expected. Darwin's bark spider (Caerostris darwini bridges large water bodies, building the largest known orb webs utilizing the toughest known silk. Here, we examine C. darwini web building behaviors to establish how bridge lines are formed over water. We also test the prediction that this spider's unique web ecology and architecture coevolved with new web building behaviors. METHODOLOGY: We observed C. darwini in its natural habitat and filmed web building. We observed 90 web building events, and compared web building behaviors to other species of orb web spiders. CONCLUSIONS: Caerostris darwini uses a unique set of behaviors, some unknown in other spiders, to construct its enormous webs. First, the spiders release unusually large amounts of bridging silk into the air, which is then carried downwind, across the water body, establishing bridge lines. Second, the spiders perform almost no web site exploration. Third, they construct the orb capture area below the initial bridge line. In contrast to all known orb-weavers, the web hub is therefore not part of the initial bridge line but is instead built de novo. Fourth, the orb contains two types of radial threads, with those in the upper half of the web doubled. These unique behaviors result in a giant, yet rather simplified web. Our results continue to build evidence for the coevolution of behavioral (web building, ecological (web microhabitat and biomaterial (silk biomechanics traits that combined allow C. darwini to occupy a unique niche among spiders.

The existing culture independent methods mainly include species specific PCR and PCR-denatured gradient gel electrophoresis/temperature gradient gel electrophoresis (PCR-DGGE/TGGE). Compared with traditional culture dependent methods, culture independent methods have some advantages such as direct, rapid, accurate and real-time, but also have disadvantages because the results may be influenced by sample complexity, DNA extraction and PCR reaction. The combined application of culture dependent and culture independent methods may provide the best estimation of polymorphism and dynamic changes of microorganisms in fermented meat.

    2004-01-01

    By applying the sinusoidal wave mode to simulate the rugged surface of bridge deck,accounting for vehicle-bridge interaction and using Euler-Bernoulli beam theory, a coupling vibration model of vehicle-bridge system was developed. The model was solved by mode analyzing method and Runge-Kutta method, and the dynamic response and the resonance curve of the bridge were obtained. It is found that there are two resonance regions, one represents the main resonance while the other the minor resonance, in the resonance curve. The influence due to the rugged surface, the vibration mode of bridge, and the interaction between vehicle and bridge on vibration of the system were discussed. Numerical results show that the influence due to these parameters is so significant that the effect of roughness of the bridge deck and the mode shape of the bridge can't be ignored and the vehicle velocity should be kept away from the critical speed of the vehicle.

  3. Urban sound ecologies

    2013-12-01

    Full Text Available Within recent years, there has been a renewed focus on sound in urban environments. From sound installations in public space to sound festivals in alternative settings, we find a common interest in sound art relating to the urban environment. Artworks or interventions presented in such contexts share the characteristics of site specificity. However, this article will consider the artwork in a broader context by re-examining how sound installations relate to the urban environment. For that purpose, this article brings together ecology terms from acoustic ecology of the sound theories of the 1970s while developing them into recent definitions of ecology in urban studies. Finally, we unfold our framing of urban sound ecologies with three case analyses: a sound intervention in Berlin, a symphony for wind instruments in Copenhagen and a video walk in a former railway station in Kassel. The article concludes that the ways in which recent sound installations work with urban ecologies vary. While two of the examples blend into the urban environment, the other transfers the concert format and its mode of listening to urban space. Last, and in accordance with recent soundscape research, we point to how artists working with new information and media technologies create inventive ways of inserting sound and image into urban environments.

    Performing accurate, realistic numerical simulations of the seismic response of long-span bridges presents a significant challenge to the fields of earthquake engineering and seismology. Suspension bridges in particular represent some of the largest and most important man-made structures and ensuring the seismic integrity of these mega-structures is contingent on accurate estimations of earthquake ground motions and accurate computational simulations of the structure/foundation system response. A cooperative, multi-year research project between the Univ. of California and LLNL was recently initiated to study engineering and seismological issues essential for simulating the response of major structures. Part of this research project is focused on the response of the long-span bridges with the San Francisco-Oakland Bay Bridge serving as a case study. This paper reports on the status of this multi-disciplinary research project with emphasis on the numerical simulation of the transient seismic response of the Bay Bridge.

  7. ECOLOGICAL ECONOMICS VS ECONOMIC(AL ECOLOGY

    Full Text Available Currently world faces the dilemma – ecological economy or economic(al ecology. The researchers produce hundreds of surveys on the topic. However the analyses of recent most cited simulations had shown the diversity of results. Thus, for some states the Kuznets environmental curve has place, for others – no. Same could be said about different years for the same state. It provokes the necessity of drawing new group analyses to reveal the tendencies and relationships between economic and environmental factors. Most flexible and mirror factor of environmental sustainability is the volume of CO2 emissions. The econometric analysis was used for detecting the economic impact on this indicator at the global level and in the spectra of group of states depending on their income. The hypothesis of the existence of environmental Kuznets curve for the analysed data is rejected. Real GDP per capita impact on carbon dioxide emissions is considered only at the global level. The impact of openness of the economy is weak. Rejection happened also to the hypothesis that for the developed countries there is a reverse dependence between the environmental pollution and economic openness. Indicator “energy consumption per capita” impacts on greenhouse gas emissions only in countries with high income. Whereby it should be noted that the more developed a country is, the more elastic is this influence. These results have a potential usage for environmental policy regulation and climate strategy.

    2013-07-01

    Full Text Available A territory, a city, a neighbourhood are all ecosystems; a mixture of chemico-physical and organic elements related to each other. That which defines an ecological system is the set of rules and characteristics which condition its relationships, and its duration in time is guaranteed by its efficiency and internal organization which applied to the city is translated in the reduction of the use of natural resources and in the increase of social organization. To increase the efficiency of the urban systems is the necessary condition for the formulation of ecological city planning favouring the maximum liveability of sites. Liveability is directly correlated to the optimization of numerous elements (public space, equipment, services, building techniques, innovative technology, social cohesion, biodiversity. To carry out such objectives, ecological city planning proposes a new model of town planning on three levels (subsoil, ground level, and upper level.

    This paper maps a coevolutionary research agenda for ecological economics. At an epistemological level coevolution offers a powerful logic for transcending environmental and social determinisms and developing a cross-disciplinary approach in the study of socio-ecological systems. We identify four consistent stories emerging out of coevolutionary studies in ecological economics, concerning: environmental degradation and development failure in peripheral regions; the lock-in of unsustainable production-consumption patterns; the vicious cycle between human efforts to control undesirable micro-organisms and the evolution of these organisms; and the adaptive advantages of other-regarding, cooperative behaviors and institutions. We identify challenges in the conceptualization of coevolutionary relationships in relation to: the interaction between different hierarchical levels of evolution; the role of space and social power; uneven rates of change and crises. We conclude with the political implications of a coevolutionary perspective based on the premises of pragmatism. (author)

    Mace, Ruth; Jordan, Fiona M

    2011-02-12

    A growing body of theoretical and empirical research has examined cultural transmission and adaptive cultural behaviour at the individual, within-group level. However, relatively few studies have tried to examine proximate transmission or test ultimate adaptive hypotheses about behavioural or cultural diversity at a between-societies macro-level. In both the history of anthropology and in present-day work, a common approach to examining adaptive behaviour at the macro-level has been through correlating various cultural traits with features of ecology. We discuss some difficulties with simple ecological associations, and then review cultural phylogenetic studies that have attempted to go beyond correlations to understand the underlying cultural evolutionary processes. We conclude with an example of a phylogenetically controlled approach to understanding proximate transmission pathways in Austronesian cultural diversity.

  13. Refining the conditions for sympatric ecological speciation.

    Débarre, F

    2012-12-01

    Can speciation occur in a single population when different types of resources are available, in the absence of any geographical isolation, or any spatial or temporal variation in selection? The controversial topics of sympatric speciation and ecological speciation have already stimulated many theoretical studies, most of them agreeing on the fact that mechanisms generating disruptive selection, some level of assortment, and enough heterogeneity in the available resources, are critical for sympatric speciation to occur. Few studies, however, have combined the three factors and investigated their interactions. In this article, I analytically derive conditions for sympatric speciation in a general model where the distribution of resources can be uni- or bimodal, and where a parameter controls the range of resources that an individual can exploit. This approach bridges the gap between models of a unimodal continuum of resources and Levene-type models with discrete resources. I then test these conditions against simulation results from a recently published article (Thibert-Plante & Hendry, 2011, J. Evol. Biol. 24: 2186-2196) and confirm that sympatric ecological speciation is favoured when (i) selection is disruptive (i.e. individuals with an intermediate trait are at a local fitness minimum), (ii) resources are differentiated enough and (iii) mating is assortative. I also discuss the role of mating preference functions and the need (or lack thereof) for bimodality in resource distributions for diversification.

    Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and ArcGIS model. Notopterygium incisum, an endangered Chinese medicinal plant, was analyzed as a case, its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province, and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude, average air temperature in September, and vegetation types were the dominant factors contributing to the grade of plant growth, precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts, while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However, slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore, there were distinguishing differences between growth suitability and quality suitability for medicinal plants, which was helpful to further research and practice of cultivation regionalization, wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.

    Full Text Available The origin of holistic social work and ecological theory was investigated. Emphasis was placed on Howard W. Odum, founding dean of the University of North Carolina School of Public Welfare, and subsequent scholarship by his sons, collaborators on the first American ecology text. Eugene and Howard Thomas Odum, internationally recognized ecological scholars, identified holism as a universal concept originating in social sciences, crediting their father’s earlier sociological work,which later bridged to ecosystems ecology. A historical review of the influential sociologists, social workers, and ecologists is presented to build the case for ecological theory transfer across the three disciplines, beginning with sociology. Critique of the current use of the ecological perspective is discussed, specifically social work’s tendency to target social systems and behavior while largely ignoring the natural environment.
