  2. Scientists in a Changed Institutional Environment: Subjective Adaptation and Social Responsibility Norms in Russia

    How do scientists react when the institutional setting in which they conduct their work changes radically? How do long-standing norms regarding the social responsibility of scientists fare? What factors influence whether scientists embrace or reject the new institutions and norms? We examine these questions using data from a unique survey of 602 scientists in Russia, whose science system experienced a sustained crisis and sweeping changes in science institutions following the collapse of the Soviet Union. We develop measures of how respondents view financing based on grants and other institutional changes in the Russian science system, as well as measures of two norms regarding scientists social responsibility. We find that the majority of scientists have adapted, in the sense that they hold positive views of the new institutions, but a diversity of orientations remains. Social responsibility norms are common among Russian scientists, but far from universal. The main correlates of adaptation are age and current success at negotiating the new institutions, though prospective success, work context, and ethnicity have some of the hypothesized associations. As for social responsibility norms, the main source of variation is age: younger scientists are more likely to embrace individualistic rather than socially-oriented norms.

Were interviewed institutions, represented by two major agencies: The Ministry of Agriculture, and Livestock (MAPA and the Brazilian Association of the Industry of Products for Pets (ABINPET; manufacturing firms; research centers based at Universities, retailers and owners of dogs and cats, totalizing five samples. It was observed that the institutions, the researchers and manufacturers consider the IN30 as an initiative of great importance by bringing self-control and self-regulation of the SAG, besides contemplating the desire of firms regarding agility in launching new technologies. However, the main concern of the researchers was related to quality assurance of food. Firms show up unssatisfied with the lack of consensus on the interpretation of some articles of IN30 by MAPA´s enforcement agents, with discrepancies between regional and the technical managers of companies, especially regarding labeling. Already retailers and owners of pets still seem unaware of the legal aspects of such normative.

  13. Institutional Change, Sustainability and the Sea

    Directory of Open Access Journals (Sweden)

    Achim Schlüter

    2013-12-01

    Full Text Available Currently, a substantial institutional change is under way for marine and coastal resources. Sustainability plays a major role therein. At the time of writing, roughly 2.3% of the marine and coastal territory has been declared a Marine Protected Area (MPA. The Convention of Biological Diversity set a target to protect 10% of the global marine environment by 2020. This move toward enclosure signifies a substantial shift away from mainly open access to at least de jure marine protected areas. What drives institutional change towards MPAs; and what role does sustainability play in this change in governance? In reflecting on these questions, the paper’s aim is to begin a dialogue on how the social-ecological system (SES analytical framework developed by Elinor Ostrom and her collaborators engages differentially with marine and coastal systems. How institutional change takes place depends on the characteristics of the resources considered and the drivers of change for the particular resource. In order to characterize the marine and coastal realm we use the social-ecological system (SES framework of Elinor Ostrom. Douglas North’s theory of institutional change is used to classify the change observed. The marine realm has ambiguous system boundaries and often high resource mobility. Uncertainties about system properties and change are much higher than for terrestrial systems. Interdependencies among different ecosystems are high, necessitating multi-level governance. Institutional change in this sector occurs under strong institutional path dependencies and competing ideologies. All these features make it particularly relevant to think about institutional change, sustainability and the current process of MPA expansion.

    Ecological economics remains unfinished in its effort to provide a framework for transforming the economy so that it is compatible with biophysical limits. Great strides have been made in valuing natural capital and ecosystem services and recognizing the need to limit the scale of economic activity, but the question of how to effectively transform the economy to limit the scale of economic activity remains unclear. To gain clarity about the institutional changes necessary to limit the scale of economic activity, it is essential that ecological economics understands the limitations of its neoclassical roots and expands its theoretical framework to include how markets are embedded in social and institutional structures. This has long been the domain of institutional economics and heterodox political economy.

Special attention is paid to the thorny issued of how political actors’ preferences are formed, with historical institutionalists considering preferences as endogenously formed, and rational choice analysts postulating that preferences are fixed and exogenous. An argument is made in favour of the perspective that considers preferences as being formed within the functioning of the political system over time, endogenously. The essay also proposes the incorporation of ideas and non-decisions as tools to elucidate processes of change.

    Full Text Available The research literature suggests that institutions for children left without parental care do not provide environments that adequately promote children’s development, and that characteristics of orphanages should be considered as an environmental factor influencing developmental difficulties in children living in institutions and later in post-institutional families. This study aimed to analyze the structural characteristics of the caregiving environment in two St. Petersburg (RF orphanages—baby homes for children from birth to 4–5 years of age (BH A and BH B, and the maintenance of the structural interventions that were implemented in BH A during 2000-05 (The St. Petersburg–USA Orphanage Research Team, 2008. Both institutions belong to the Ministry of Health and are managed under the same medical regulations, providing about the same quality of medical care and nutrition. The results of the study show that the number of children living in each ward (4 to 6 in BH A and 5 to 8 in BH B, and the child–caregiver ratio (2 to 3 for BH A and 2.5 to 4 for BH B in the two baby homes are about the same, while BH A have fewer staff members who are assigned to the ward (6–8 vs. 9–14 in BH B. The ward assistant teachers in BH A are assigned as the primary caregivers, working 5 days a week (39 hrs vs. about 25 hrs a week for assistant teachers in BH B. While living in the baby home, children in BH A are integrated by age and disability (vs. segregation by age and partial disability integration in BH B, and are assigned to one ward (meaning the same caregivers, peers, rooms, etc., while in BH B the children change their ward when they reach a certain age or developmental milestone (number of wards children experienced M(SD = 1.1 (0.2 in BH A and 2.7 (1.1 in BH B.

    Objective. This study examined institutional anomie theory in the context of transitional Russia. Methods. We employed an index of negative socioeconomic change and measures of family, education, and polity to test the hypothesis that institutional strength conditions the effects of poverty and socioeconomic change on homicide rates. Results. As expected, the results of models estimated using negative binomial regression show direct positive effects of poverty and socioeconomic change and direct negative effects of family strength and polity on regional homicide rates. There was no support, however, for the hypothesis that stronger social institutions reduce the effects of poverty and socioeconomic change on violence. Conclusions. We interpret these results in the Russia-specific setting, concluding that Russia is a rich laboratory for examining the effects of social change on crime and that empirical research in other nations is important when assessing the generalizability of theories developed to explain crime and violence in the United States.

  8. Institutions, Technological Change and Economic Growth

    Full Text Available Theories of economic growth try to explain variations in per capita income across countries by differences in capital accumulation and productivity. However, many scholars consider that integrating institutions into economic theory and economic history is an essential step in improving explanations of why some societies are richer than others. This paper develops the empirical and theoretical case that differences in institutions are the fundamental cause of differences in technological change (productivity, hence in economic growth. First, I give a definition of institutions and how they influence economic performance, from a New Institutional Economics point of view. Then, I introduce the theoretical framework based on the economics of ideas and endogenous growth models. Finally, I argue that R&D expenditures -a proxy for technological change- will vary across countries depending on some measures of institutional quality. In the end, this paper finds that stronger institutions (measured by an aggregate of institutional quality encourage greater R&D expenditures. At a disaggregate level, the rule of law is positively correlated and the regulatory burden is negatively correlated with R&D expenditures. Human capital level (measured by the tertiary and primary school enrolment rates has also a significant positive impact in R&D expenditures.

    Corporate social responsibility is the product of the fact that enterprises are forced to adapt to the changes of institutional environment for survival. With the changes of institutional environment, the development of Western corporate social responsibility can be divided into three phases; unconscious, illuminative and mature stages. Since 1949, there has been the "abnormality"about the function of corporate social responsibility for Chinese enterprises both in the institutional environment of planned economy system and the process of transformation advanced from the planned economy system to the market economy system, say, "enterprise shouldering social responsibility" in the planned economy period and highlighting" nature of economic individual" in the process of transformation towards the market economy. Currently, the conflict between corporate interests and social interests is becoming more prominent. Besides, people' s expectation for better human dignity and social justice is rising. As a result, corporate social responsibility becomes more serious and receives much more attention from both leaders and masses in China. Meanwhile, Chinese Communist Party issues a call of "scientific development". Amid institutional environment of scientific development, Chinese enterprises are expected to take corporate social responsibility. The realization of Chinese enterprises ' social responsibility must be guranteed by institutional construction say, requiring clarity of enterprise property right system,legalization of CSR( corporate social responsibility) ,scientization of evaluation system of CSR, system of information disclosure of CSR, and diversity of supervisors of CSR.%摘要企业社会责任是指企业在创造利润、对股东利益负责的同时,还应承担对员工、社会和环境的责任,包括遵守商业道德、生产安全、职业健康、保护消费者合法权益、节约资源等.企业承担社会责任是企业为生存而适应制度

    Limited by the condition of information, technology and natural elements, the compulsive institutions in the environment governance can not form a “hard constraint” to the individuals. Because of the individual's speculative behaviors, the government's deviation from its environmental governance, and the non-cooperative game between individuals and the legal organization, the implementation of the compulsive institutions is not as good as being expected. Through analyzing the mechanism of the compulsive institutions, this paper puts forward some suggestions to enhance the efficiency of such institutions' implementation.

  19. Evolution in a changing environment.

    Directory of Open Access Journals (Sweden)

    Andrea Baronchelli

    Full Text Available We propose a simple model for genetic adaptation to a changing environment, describing a fitness landscape characterized by two maxima. One is associated with "specialist" individuals that are adapted to the environment; this maximum moves over time as the environment changes. The other maximum is static, and represents "generalist" individuals not affected by environmental changes. The rest of the landscape is occupied by "maladapted" individuals. Our analysis considers the evolution of these three subpopulations. Our main result is that, in presence of a sufficiently stable environmental feature, as in the case of an unchanging aspect of a physical habitat, specialists can dominate the population. By contrast, rapidly changing environmental features, such as language or cultural habits, are a moving target for the genes; here, generalists dominate, because the best evolutionary strategy is to adopt neutral alleles not specialized for any specific environment. The model we propose is based on simple assumptions about evolutionary dynamics and describes all possible scenarios in a non-trivial phase diagram. The approach provides a general framework to address such fundamental issues as the Baldwin effect, the biological basis for language, or the ecological consequences of a rapid climate change.

The meetings were chaired by two or more leaders from within the disciplinary focus of each session. 222 scholars for a total of 1097 participants-days were convened under the auspices of this award. The overall goal of each AGCI session is to further the understanding of Earth system science and global environmental change through interdisciplinary dialog. The format and structure of the meetings allows for presentation by each participant, in-depth discussion by the whole group, and smaller working group and synthesis activities. The size of the group is important in terms of the group dynamics and interaction, and the ability for each participant's work to be adequately presented and discussed within the duration of the meeting, while still allowing time for synthesis

    Full Text Available L’évolution de l’environnement alpin au XXIe siècle sera conditionnée par le changement climatique. Celui-ci pourrait conduire à des climats inconnus à ce jour dans les Alpes, avec comme conséquence une crise environnementale majeure et durable. Face à ces défis, les financements de recherche restent insuffisants pour la recherche appliquée aux milieux de montagne. Les financements nationaux privilégient souvent la recherche polaire au détriment des hautes altitudes, alors que les financements de type Interreg prennent insuffisamment en compte les besoins de recherche fondamentale, préalable nécessaire à l’élaboration de scénarios. Une évolution se dessine depuis deux ou trois ans vers des projets en réseau à l’échelle alpine. Le présent article fait le point sur les principaux enjeux qui attendent la recherche environnementale alpine et sur la capacité des programmes de recherche à répondre aux besoins. La première partie sur les changements climatiques est fondée sur les rapports récents : rapport de synthèse IPCC 2007 (IPCC 2007, rapport IPCC sur l’Europe (Alcamo et al. 2007, rapport de synthèse du programme ClimChAlp (Prudent-Richard et al., 2008.

This could lead to climates never before seen in the Alps, resulting in a major and lasting environmental crisis. In the face of these challenges, funding is still insufficient for specialised research on mountain environments. State funding often prioritises polar research at the expense of high altitude areas, whereas funding schemes from bodies such as Interreg do not sufficiently address the need for fundamental research, which is nevertheless a necessary first step prior to

    2017-02-01

    Many healthcare scholars have applied institutional theories to the study of management accounting systems (MAS) change. However, little attention has been devoted to MAS change within groups. Kostova et al. highlight the limitations of traditional institutional frameworks in studying groups since they are characterised not only by the existence of external institutional environments but also by intra-organisational (meso-level) ones. Given this background, the research question is: how does the meso-level institutional environment affect MAS change in healthcare groups? We use a longitudinal multiple-case study design to understand the role of headquarters in shaping local MAS change. We would expect companies to adopt similar MAS. However, we argue that the relationship between external institutions and MAS change cannot be wholly understood without taking into consideration the role of headquarters. Our analysis shows how hospitals facing the same external institutional environment implement different MAS as a consequence of different parenting styles. From a scientific perspective, our article contributes to broaden traditional institutional theoretical frameworks.

  15. Book Review: Institutional Repositories: Content and Culture in an Open Access Environment

    Directory of Open Access Journals (Sweden)

    Isabel Galina

    2007-12-01

    Full Text Available As repository technology matures, the cultural and organizational aspects of setting up and running an institutional repository have come to the forefront of the discussion surrounding their deployment. The book deliberately does not discuss any software in particular but focuses more on identifying key stake holders in the changing information environment and their role in the institutional repository scenario with regard to strategic and policy issues. Key aspects such as advocacy, user engagement, content policy, preservation and curation are covered in a clear and practical fashion, drawing on the author’s experience of running an institutional repository. Although the book covers important and relevant issues, it is occasionally uneven in its depth and coverage, dealing with some aspects in great detail and only briefly mentioning others. A short introductory chapter creates the framework for the book by providing a definition of institutional repositories, followed by a very broad second chapter entitled The Changing Information Environment. In this chapter key stake holders are identified and described, followed by a general section describing the Open Access movement and finishing by describing certain online information tools such as Flickr and Wikipedia in quite some detail. Although it is clear that the intention is to place institutional repositories within the wider information content, it would have been interesting if the author had mentioned for example, Cyber infrastructure or eScience projects which are important frameworks for future digital networks and academic communication and publishing.

  16. [Environment and political institutions between antiquity and contemporary medicine].

    Science.gov (United States)

    Angeletti, L R

    1995-01-01

    In both myth and Genesis (by God) the creation of the world begins with the separation of water, sky/air and ground; later appear the life and the man and from Olympic divinities (or God) derive health and disease and remedies. When Milesian philosophers distinguished between nature (to be observed) and speculation, a parallel revision has been made in the medicine, from theurgical to rational one. Thus, Hippocratic medicine pointed attention on air waters and places as natural environmental elements, to be observed, as method to understand the probable diseases of a city, also with a role of political institutions, says the Hippocratic treatise De aëre. Centuries later, only in the 19th century has been rediscovered the importance of environment in the health's policy, a concept full developed in the last time (i.e. health and pollution, health and quality of life).

  18. Contracts or Scripts? A Critical Review of the Application of Institutional Theories to the Study of Environmental Change

    Directory of Open Access Journals (Sweden)

    Samy Hotimsky

    2006-06-01

    Full Text Available The impact of new institutionalism on the study of human environment interactions has been meaningful. Institutional perspectives have further shaped and modified the field problems of common pool resources, environmental hazards, and risk and environmental management. Given the relative potential of institutional theories to increase the comprehension of the various dimensions of human-environmental interactions, it has become increasingly important to attempt to consolidate different interpretations of what institutions are, and how they mediate and constrain possibilities for more successful environmental outcomes. This article focuses primarily on contending ontological perspectives on institutions and institutional change. It argues that what should guide the application of institutional theories in practical research regarding environmental change is the ontological dimension, and that the focus of research should be on uncovering the underlying dynamics of institutional change. In doing so, it calls for a methodological pluralism in the investigation of the role institutions play in driving/managing for environmental change.

  19. Protecting The Environment: Green Microfinance Or Green Micro Finance Institutions?

    Directory of Open Access Journals (Sweden)

    Fabio Daneri

    2015-03-01

    Full Text Available This paper represents a critical review of several papers and books written on the subjects of microfinance, poverty and environmental protection. It aims at linking the different themes and also to offer specific suggestions on how microfinance can provide solutions which are beneficial to the environment. The paper also concentrates on the disparities between rich and poor and how they influence the implementation of environmentally damaging activities. These activities are in fact implemented with a clear damage to the poor, especially at local level, where the poor has difficulties to protect itself due to the differences in power between the rich and the poor. Particular attention is also dedicated to the issue of environmental sustainability vs. Microfinance Institutions’ sustainability since the promotion of environmental activities implies costs to be born by Micro Finance Institutions. In fact, it must be highlighted that sustainability is a fundamental issue for MFis. The majority of MFIs normally struggle for their existence, since their objective is to work with poor and difficult clients and they mainly operate in very difficult business environments. The financial sustainability of MFIs is therefore a crucial prerequisite for the provision of financial services to the poor layers of the population. Additional costs concerning environmental protection can be born only if adequate financial support is provided by external donors

    2013-10-01

    Of recent interest is the capacity of international health agencies to adapt to changes in the global health environment and country needs. Yet, little is known about the potential benefits of using social science institutional theory, such as path dependency and institutional change theory, to explain why some international agencies, such as the WHO and the Global Fund to Fight AIDS, Tuberculosis and Malaria, fail to adapt, whereas others, such as the World Bank and UNAIDS, have. This article suggests that these institutional theories can help to better understand these differences in international agency adaptive capacity, while highlighting new areas of policy research and analysis.

  3. Economic institutions and institutional change in the United States electric power industry

    Science.gov (United States)

    Wisniewski, Lorel Elaine

    Historical data from the U.S. electric power industry was used to test two theories of institutional change. A transactions costs theory based on the neoclassical model was tested against a strategic bargaining model of institutional change. A comparative test of the two models supports the strategic bargaining theory, finding that relative bargaining power can influence the course of institutional change when the power advantage is held by a player who expects to reap economic gains from the change. This result has implications for expectations regarding the nature of economic institutions in that efficient institutions would not be expected to emerge if outcomes are determined by asymmetries in bargaining power. Estimation of a cost function using recent firm-level panel data from the electric power industry found no statistically significant cost differentials between publicly owned and privately owned electric utilities. Transactions costs, measured at the level of the firm, were included as an explanatory variable. The model was estimated as a one-way, fixed effects model to account for institutional variation between firms. Institutional variation was found to lead to cost differentials between individual firms, but not by ownership sector. The cost functions estimated were found to differ structurally by ownership sector, suggesting that public and private electric utilities may utilize different input combinations.

    Full Text Available The aim of this article is to analyze whether the institutional environment has a direct effect on Corporate Social Responsibility (CSR reporting practices or if this effect is explained by the influence of the institutional environment on Corporate Governance (CG mechanisms. To conduct our study, we focused on two countries that reflect different types of institutional environment: relation-based (Brazil and rule-based (Spain. Based on our results, we can affirm that the institutional environment influences CG mechanisms (Board Size and Reference Shareholder as well as companies’ CSR disclosure. Additionally, the CG mechanisms affected by the institutional environment also help to explain differences in CSR reporting practices. As relation-based societies evolve into rules-based environments, the information disclosed about CSR becomes more complex due to a strengthening of CG mechanisms.

    Full Text Available Firms in the agri-food industry are embedded in a system of institutions, regulations and policies that shape their economic environment and affect their conduct and performance. Changes in this system can propose new challenges for the firms that need to adequately and efficiently change and adapt to the emerging environment. The following article examines how deep structural changes in the institutional and regulatory setting can be effectively addressed by organizational innovation and what can be the catalysts behind a successful innovation effort. In doing so the analysis examines the case of Valio, the largest Finnish dairy company and its reconstruction effort due to Finland’s EU accession in 1995. After years of restructuring and changing its business model the company remains a major player in Finland and one of the most well-known brands in the region.

    In this study we consider a mathematical model of a sexual population that lives in a changing environment. We find that a low rate of environmental change can produce a very large increase in genetic variability. This may help to explain the high levels of heritability observed in many natural populations. We also study asexuality and find that a modest rate of environmental change can be very damaging to an asexual population, while leaving a sexual population virtually unscathed. Furthermore, in a changing environment, the advantages of sexuality over asexuality can be much greater than suggested by most previous studies. Our analysis applies in the case of very large populations, where stochastic forces may be neglected. PMID:10511577

    Energy Technology Data Exchange (ETDEWEB)

    Wilbanks, Thomas J [ORNL

    2011-01-01

    This overview chapter considers five questions that cut across the four case studies in the section to follow: (1) why are urban environments of particular interest; (2) what does an 'urban environment' mean as a focus for adaptation actions, (3) what do we know about climate change vulnerabilities and adaptation potentials in urban areas; (4) what can we expect in the future with adaptation in urban areas; and (5) what is happening with climate change adaptation in urban areas? After decades of inattention, adaptation to risks and impacts of climate change is now receiving long overdue attention, and it is only natural that a considerable share of this attention is focused on the places where most people live. This section considers climate change adaptation in the urban environment, defined as settings where human populations cluster - generally implying relatively large clusters, but not excluding smaller settlements that operate as coherent geopolitical and economic entities. Consistent with the topic of the book, the emphasis of this overview will be on urban environments in developed countries, but it will also draw on knowledge being developed from urban experiences across the globe.

  18. Transdisciplinary Sustainability Science at Higher Education Institutions: Science Policy Tools for Incremental Institutional Change

    Directory of Open Access Journals (Sweden)

    Tom Dedeurwaerdere

    2013-09-01

    Full Text Available At the very moment that humanity is facing a broadening ecological crisis, and that both policy makers and civil society are calling for a transition towards more sustainable societies, modern science seems incapable of providing operational solutions for managing this transition. In this context, both Noble prize laureates and high-level science officials have stressed the need of an in depth transformation of the modes of organization of scientific research for governing the transition to sustainable societies. However, existing analyses of on-going initiatives show that most of the barriers to a major, consolidated effort in sustainability science will not be removed without far-reaching institutional change. To address this challenge, this paper proposes an incremental institutional change approach, based on a gradual institutionalization process of existing initiatives. The analysis in this paper shows that strategic research for sustainability and reform of research funding mechanisms will only be effective if they are supported at the same time by reforms of career and training paths at higher education institutions. To promote this vision, the paper proposes a set of capacity building measures that can be undertaken at the level of research funding, higher education institutions and networking.

  20. Probabilistic adaptation in changing microbial environments

    Directory of Open Access Journals (Sweden)

    Yarden Katz

    2016-12-01

    Full Text Available Microbes growing in animal host environments face fluctuations that have elements of both randomness and predictability. In the mammalian gut, fluctuations in nutrient levels and other physiological parameters are structured by the host’s behavior, diet, health and microbiota composition. Microbial cells that can anticipate environmental fluctuations by exploiting this structure would likely gain a fitness advantage (by adapting their internal state in advance. We propose that the problem of adaptive growth in structured changing environments, such as the gut, can be viewed as probabilistic inference. We analyze environments that are “meta-changing”: where there are changes in the way the environment fluctuates, governed by a mechanism unobservable to cells. We develop a dynamic Bayesian model of these environments and show that a real-time inference algorithm (particle filtering for this model can be used as a microbial growth strategy implementable in molecular circuits. The growth strategy suggested by our model outperforms heuristic strategies, and points to a class of algorithms that could support real-time probabilistic inference in natural or synthetic cellular circuits.

  1. Institutional Changes and Globalisation Alter the Landscape of Chinese Auto Industry

    2007-01-01

    In light of the institutional environment transformation and globalisation, this article draws on institutional theory and global value chain theory to explore the growth path of China’s state-owned automakers. The study finds that the institution and globalisation factors have become the growth driver of state-owned automakers. At each stage, it is found that there is a convergence in the organisational behaviour of state-owned automakers. The change in driving force, has, however, led to the transformation of organisational behaviour of those state-owned automobile enterprises undergoing the process of evolving from a joint venture model to a proprietary innovation model. This change has come about due to the leveraging of partnership opportunities with multinational motor companies.

  2. Institutional Level Identity Control Strategies in the Distance Education Environment: A Survey of Administrative Staff

    Full Text Available Physical separation of students and instructors creates the gap of anonymity and limited control over the remote learning environment. The ability of academic institutions to authenticate students and validate authorship of academic work at various points during a course is necessary for preserving not only perceived credibility but also public safety. With the growing scope of distance education programs that permeate critical areas such as healthcare, airspace, water management, and food solutions, universities have a moral obligation to employ secure measures to verify learning outcomes. This study examines the measures universities with large distance education programs employ to align identity of learners with the academic work they do, as well as the effectiveness of and challenges and barriers to their implementation. The research was undertaken using a multiple case approach and examined survey responses from five academic administrators at five officially accredited post secondary institutions in three countries. The cases examined in the study include: Athabasca University, Open University UK, Penn State University World Campus, University of Maryland University College, and eConcordia, Concordia University’s distance learning facility. This study is not an exhaustive attempt to examine all aspects of academic integrity, but rather to create awareness about various learner authentication strategies. This study confirms that secure learner authentication in the distance education environment is possible. However, with greater pressure to enhance security of learner authentication, the openness of open learning is challenged and may change as we know it.

    BACKGROUND: Lifestyle variables may serve as important intermediate factors between psychosocial work environment and health outcomes. Previous studies, focussing on work stress models have shown mixed and weak results in relation to weight change. This study aims to investigate psychosocial...... factors outside the classical work stress models as potential predictors of change in body mass index (BMI) in a population of health care workers. METHODS: A cohort study, with three years follow-up, was conducted among Danish health care workers (3982 women and 152 men). Logistic regression analyses...... examined change in BMI (more than +/- 2 kg/m(2)) as predicted by baseline psychosocial work factors (work pace, workload, quality of leadership, influence at work, meaning of work, predictability, commitment, role clarity, and role conflicts) and five covariates (age, cohabitation, physical work demands...

  4. Adaptive robot path planning in changing environments

    Energy Technology Data Exchange (ETDEWEB)

    Chen, P.C.

    1994-08-01

    Path planning needs to be fast to facilitate real-time robot programming. Unfortunately, current planning techniques are still too slow to be effective, as they often require several minutes, if not hours of computation. To overcome this difficulty, we present an adaptive algorithm that uses past experience to speed up future performance. It is a learning algorithm suitable for incrementally-changing environments such as those encountered in manufacturing of evolving products and waste-site remediation. The algorithm allows the robot to adapt to its environment by having two experience manipulation schemes: For minor environmental change, we use an object-attached experience abstraction scheme to increase the flexibility of the learned experience; for major environmental change, we use an on-demand experience repair scheme to retain those experiences that remain valid and useful. Using this algorithm, we can effectively reduce the overall robot planning time by re-using the computation result for one task to plan a path for another.

  6. Designing institutions for climate change: Why rational design involves technology

    Energy Technology Data Exchange (ETDEWEB)

    Coninck, H. de [Energy Research Centre of the Netherlands, Petten (Netherlands)

    2008-09-30

    This paper aims to explore how to augment the institutional solutions offered by current political theory for addressing the unprecedented problem of climate change. Although steering directly at emission reductions in an international treaty has benefits in terms of cost-effectiveness, the paper arrives at the conclusion that considerations around technological development should be drawn into the treaty equation in order to generate sufficient reciprocity to have a politically feasible international regime. It then argues that the benefits of technology agreements for climate change mitigation may be larger than commonly assumed, as they - if properly designed - could lead to real emission reductions and provide more flexibility to reach agreement in post-2012 negotiations than proposals modelled exclusively on the Kyoto Protocol or other types of absolute emission targets. Based on rational design of international institutions for environmental governance, and attempting to take into account considerations of technological dynamics and the 'sociotechnical system', contours of a possible environmentally effective and politically feasible international climate change agreements are sketched.

  8. The Changing Role of ENGOs in Water Governance: Institutional Entrepreneurs?

    Science.gov (United States)

    Davidson, Seanna L.; de Loë, Rob C.

    2016-01-01

    The changing role of the state in the last quarter century has been an important contemporary concern for policy makers, scholars, and the public. Equally, there is increasing recognition among governance scholars that nongovernment actors are exerting new kinds of influence over governance systems and contributing in novel ways to governance processes. The role of environmental nongovernmental organizations (ENGOs) is particularly pertinent given the continued involvement of ENGOs within collaborative, adaptive, and co-management governance, across several contexts and regions. This paper uses an analytical framework derived from recent studies on institutional entrepreneurs, to examine the skills ENGOs are applying in order to orchestrate change. An empirical case of governance for water in Canada's Lake Simcoe region provides the foundation for the research. Drawing on a mixed methods approach, the research finds that ENGOs in Lake Simcoe have taken on a role as an institutional entrepreneur, and thereby have altered the relationship between governance actors in this setting. A key outcome of their actions is a more dominant, engaged, and influential role for ENGOs in a critical, regional governance system.

  9. Seabed change detection in challenging environments

    Matthews, Cameron A.; Sternlicht, Daniel D.

    2011-06-01

    Automatic Change Detection (ACD) compares new and stored terrain images for alerting to changes occurring over time. These techniques, long used in airborne radar, are just beginning to be applied to sidescan sonar. Under the right conditions ACD by image correlation-comparing multi-temporal image data at the pixel or parcel level-can be used to detect new objects on the seafloor. Synthetic aperture sonars (SAS)-coherent sensors that produce fine-scale, range-independent resolution seafloor images-are well suited for this approach; however, dynamic seabed environments can introduce "clutter" to the process. This paper explores an ACD method that uses salience mapping in a global-to-local analysis architecture. In this method, termed Temporally Invariant Saliency (TIS), variance ratios of median-filtered repeat-pass images are used to detect new objects, while deemphasizing modest environmental or radiometric-induced changes in the background. Successful tests with repeat-pass data from two SAS systems mounted on autonomous undersea vehicles (AUV) demonstrate the feasibility of the technique.

Schlüchter / Institut für Geologie, Univ. Bern, CH Climate change as seen by a geologist Glaciers are an integrated part of the high altitudes and the high latitudes of our planet. They are sensitive to temperature and moisture changes and adjust their mass balances accordingly. By doing so they interact with their substratum, the geological basement and they produce characteristic imprints of their presence, their variability and their disappearance. In glacial geology and paleoglaciology such imprints of former glaciers are carefully recorded, mapped and, hopefully, dated in order to obtain amplitude and periodicity records of their changes - as forced by changing climate, as we believe. In the upcoming lectures three aspects will be discussed: the last glaciation in the Swiss Alps. A reconstruction is shown based on fieldwor...

    Using a sample of 1486 Chinese A-share listed companies for the period 2004-2008,this study empirically tests the impact of family control,institutional environment and their interaction on the cash dividend policy of listed companies.Our results indicate that(1)family firms have a lower cash dividend payout ratio and propensity to pay dividends than non-family firms;(2) a favorable regional institutional environment has a significant positive impact on the cash dividend payout ratio and propensity to pay dividends of listed companies;and(3) the impact of the regional institutional environment on cash dividends is stronger in family firms than in non-family firms.Somewhat surprisingly,we find that controlling family shareholders in China may intensify Agency Problem Ⅰ(the owner-manager conflict) rather than Agency Problem Ⅱ(the controlling shareholder-minority shareholder conflict),and thus have a significant negative impact on cash dividend policy.In contrast,a favorable regional institutional environment plays a positive corporate governance role in mitigating Agency Problem 1 and encouraging family firms to pay cash dividends.

    Global environmental changes such as climate change result from the interaction of human and natural systems. Research to understand these changes and options for addressing them requires the physical, environmental, and social sciences, as well as engineering and other applied fields. In this essay, we describe how the Aspen Global Change Institute (AGCI) has provided leadership in global change science over the past 25 years—in particular how it has contributed to the integration of the natural and social sciences needed to research the drivers of change, Earth system response, natural and human system impacts, and options for risk management. We illustrate the ways the history of AGCI has been intertwined with the evolution of global change science as it has become an increasingly interdisciplinary endeavor.

In this research the instrumental rationality was manifested by the service providers and consultants who played a pivotal role in the construction of new governance in the field of facilities services in the Netherlands. Further, the role of institutional rationality was investigated wherein it was found that the logic of rationalization shaped the governance in the field of facilities services. Moreover, the implication for the explanation of practice variation by institutional theory is discussed.

  1. The context of discrimination: workplace conditions, institutional environments, and sex and race discrimination charges.

    Science.gov (United States)

    Hirsh, C Elizabeth; Kornrich, Sabino

    2008-03-01

    This article explores the organizational conditions under which discrimination charges occur. Drawing on structural and organizational theories of the workplace, the authors demonstrate how organizational conditions affect workers' and regulatory agents' understandings of unlawful discrimination. Using a national sample of work establishments, matched to discrimination-charge data obtained from the Equal Employment Opportunity Commission (EEOC), the authors examine how characteristics of the workplace and institutional environment affect variation in the incidence of workers' charges of sex and race discrimination and in the subset of discrimination claims that are verified by EEOC investigators. The findings indicate that workplace conditions, including size, composition, and minority management, affect workers' charges as well as verified claims; the latter are also affected by institutional factors, such as affirmative action requirements, subsidiary status, and industrial sector. These results suggest that internal workplace conditions affect both workers' and regulatory agents' interpretations of potentially discriminatory experiences, while institutional conditions matter only for regulatory agents' interpretations of those events.

    2016-01-01

    Diversity in academia requires attention, especially with the expected increase in minority populations in the United States (American Association of Colleges of Nursing, (AACN) 2014). Despite theoretical papers that suggest that several challenges are encountered by minority faculty employed in predominately White institutions, a dearth of research on this topic has been published. The purpose of this literature review was to analyze the published research that addressed the workplace environment of African-American faculty employed in predominately White institutions. In utilizing the keywords in various combinations, 236 articles were retrieved through multiple databases. After applying inclusion and exclusion criteria, 15 studies were reviewed with only three related to nursing. Two themes were extracted from the review: 1) the cultural climate of the workplace environment and, 2) underrepresentation of African-American faculty. It is apparent from this review that additional research is needed to understand the experiences of this group of faculty to target effective recruitment and retention strategies.

    2014-06-30

    Seagrass meadows are valuable ecosystem service providers that are now being lost globally at an unprecedented rate, with water quality and other localised stressors putting their future viability in doubt. It is therefore critical that we learn more about the interactions between seagrass meadows and future environmental change in the anthropocene. This needs to be with particular reference to the consequences of poor water quality on ecosystem resilience and the effects of change on trophic interactions within the food web. Understanding and predicting the response of seagrass meadows to future environmental change requires an understanding of the natural long-term drivers of change and how these are currently influenced by anthropogenic stress. Conservation management of coastal and marine ecosystems now and in the future requires increased knowledge of how seagrass meadows respond to environmental change, and how they can be managed to be resilient to these changes. Finding solutions to such issues also requires recognising people as part of the social-ecological system. This special issue aims to further enhance this knowledge by bringing together global expertise across this field. The special issues considers issues such as ecosystem service delivery of seagrass meadows, the drivers of long-term seagrass change and the socio-economic consequences of environmental change to seagrass.

  6. The uneven results of institutional changes in Central and Eastern Europe: The role of culture

    Directory of Open Access Journals (Sweden)

    Pejović Svetozar

    2004-01-01

    Full Text Available It has been widely observed that the same formal rules, enacted in the parliaments in the form of written laws, give vastly different results in different social and cultural environments. This phenomenon came to be particularly pronounced in the process of transition of the formerly communist countries to market economies and politically pluralized societies. Highly similar and occasionally identical institutional changes turned out to be unequally accepted by the societies under consideration and produced widely different results in the material restructuring of the economies. It became clear that the notion of institutions had to be widened so as to encompass the informal rules: the customs, the traditions, cultural values and national myths. Informal rules define the constraints for implementing the formal ones and, on the other hand, determine the actual effects of the latter once they are implemented. Forcing the formal rules upon the transition societies cannot be successful unless preceding and/or contemporaneous changes of informal rules are provided for. The paper ends with a design of the strategy for the decisively important changes in values and other components of informal rules.

Fundamentally, I contend that a democratic system needs to provide arenas of deliberation in order to contest gender relations and eradicate practices of domination. Moreover, I argue that the exclusion and censorship of groups that question the predominant gender practices contradicts the spirit of democracy. Therefore, if women do not find institutional paths to express their ideas and to materialize their desires and beliefs, democratic institutions must be designed so as to enable these processes of inclusion.

    1997-06-01

    The Center for Energy Education (CEE) is a partnership linking the University of Oklahoma, Close Up Foundation and Department of Energy. Based upon the theme of energy, environment and public policy, the CEE`s main purposes are to: (1) educate teachers on energy sources, environmental issues and decisionmaking choices regarding public policy; (2) develop interdisciplinary curricula that are interactive in nature (see attachments); (3) disseminate energy education curricula; (4) serve as a resource center for a wide variety of energy education materials; (5) provide a national support system for teachers in energy education; and (6) conduct research in energy education. The CEE conducted its first two-week experimentially-based program for educators during the summer of 1993. Beginning at the University of Oklahoma, 57 teachers from across the country examined concepts and issues related to energy and environment, and how the interdependence of energy and environment significantly influences daily life. During the second week of the institute, participants went to Washington, D.C. to examine the processes used by government officials to make critical decisions involving interrelationships among energy, environment and public policy. Similar institutes were conducted during the summers of 1994 and 1995 resulting in nearly 160 science and social studies educators who had participated in the CEE programs. Collectively the participants represented 36 states, the Pacific Territories, Puerto Rico, and Japan.

    Full Text Available Entrepreneurship is the cornerstone of a modern competitive economy. Because of the economic and social importance attributed to entrepreneurship, every country has adopted policies aiming to encourage and to support entrepreneurial attitudes and behaviors. Despite the fact that the set of public policy measures is very similar across countries and regions, the outcomes are different. The differences can be observed not only in quantitative terms (i.e. number of newly established ventures, but also in qualitative terms (i.e. proportion of innovative firms, intensity of knowledge and technological level, degree of internationalization etc.. Indeed, entrepreneurship takes different forms ranging from an alternative to employment (self-employed to creation of innovative, competitive and fast growing enterprises. It is also recognized the corporate entrepreneurship, the social entrepreneurship and even the entrepreneurship in the public sector. Different forms of entrepreneurship have a different impact in terms of general progress. Scholars have shown that context is an important factor explaining the variability of entrepreneurship outcomes, calling for a better understanding of the business environment influence on the intensity and quality of the entrepreneurial activity.

    During last decade, considerable interest has been focused to assess the influence of human activities on ecosystems. The increasing trend in the atmospheric concentration of CO{sub 2} has been predicted to continue till the next century and the amount of nitrogen deposition in the northern hemisphere has increased markedly. Substantial interest has been focused on predicting how these changes will affect on plants. Most boreal mire ecosystems are dominated by mosses of the genus Sphagnum, the litter of which constitutes the main component in the peat deposits and is an important CO{sub 2} sink via peat formation. Since virtually nothing was known about the growth response of peat mosses to elevated concentrations of CO{sub 2} and alerting changes in species composition were detected in the sensitive ombrotrophic mire vegetation under increased N deposition in central Europe, this study was established. Laboratory experiments focused on measurements of the patterns of growth, production and plant metabolism at increased CO{sub 2} and N deposition levels in peat moss species. Long term field experiments were established to study the growth response and spatial competition of two interacting Sphagnum species under the increased nitrogen deposition levels

  3. Essays in energy, environment and technological change

    Science.gov (United States)

    Zhou, Yichen Christy

    This dissertation studies technological change in the context of energy and environmental economics. Technology plays a key role in reducing greenhouse gas emissions from the transportation sector. Chapter 1 estimates a structural model of the car industry that allows for endogenous product characteristics to investigate how gasoline taxes, R&D subsidies and competition affect fuel efficiency and vehicle prices in the medium-run, both through car-makers' decisions to adopt technologies and through their investments in knowledge capital. I use technology adoption and automotive patents data for 1986-2006 to estimate this model. I show that 92% of fuel efficiency improvements between 1986 and 2006 were driven by technology adoption, while the role of knowledge capital is largely to reduce the marginal production costs of fuel-efficient cars. A counterfactual predicts that an additional 1/gallon gasoline tax in 2006 would have increased the technology adoption rate, and raised average fuel efficiency by 0.47 miles/gallon, twice the annual fuel efficiency improvement in 2003-2006. An R&D subsidy that would reduce the marginal cost of knowledge capital by 25% in 2006 would have raised investment in knowledge capital. This subsidy would have raised fuel efficiency only by 0.06 miles/gallon in 2006, but would have increased variable profits by 2.3 billion over all firms that year. Passenger vehicle fuel economy standards in the United States will require substantial improvements in new vehicle fuel economy over the next decade. Economic theory suggests that vehicle manufacturers adopt greater fuel-saving technologies for vehicles with larger market size. Chapter 2 documents a strong connection between market size, measured by sales, and technology adoption. Using variation consumer demographics and purchasing pattern to account for the endogeneity of market size, we find that a 10 percent increase in market size raises vehicle fuel efficiency by 0.3 percent, as compared

    Our modern age is defined by an astounding capacity to generate scientific information. From DNA to dark matter, human ingenuity and technologies create an endless stream of data about ourselves and the world of which we are a part. Yet we largely founder in transforming information into understanding, and understanding into rational action for our society as a whole. Earth and biodiversity scientists are especially frustrated by this impasse because the data they gather often point to a clash between Earth's capacity to sustain life and the decisions that humans make to garner the planet's resources. Immersive virtual environments offer an underexplored link in the translation of scientific data into public understanding, dialogue, and action. The Worldviews Network is a collaboration of scientists, artists, and educators focused on developing best practices for the use of immersive environments for science-based ecological literacy education. A central tenet of the Worldviews Network is that there are multiple ways to know and experience the world, so we are developing scientifically accurate, geographically relevant, and culturally appropriate programming to promote ecological literacy within informal science education programs across the United States. The goal of Worldviews Network is to offer transformative learning experiences, in which participants are guided on a process integrating immersive visual explorations, critical reflection and dialogue, and design-oriented approaches to action - or more simply, seeing, knowing, and doing. Our methods center on live presentations, interactive scientific visualizations, and sustainability dialogues hosted at informal science institutions. Our approach uses datasets from the life, Earth, and space sciences to illuminate the complex conditions that support life on earth and the ways in which ecological systems interact. We are leveraging scientific data from federal agencies, non-governmental organizations, and our

    The people who use Federal buildings — Federal employees, operations and maintenance staff, and the general public — can significantly impact a building’s environmental performance and the consumption of energy, water, and materials. Many factors influence building occupants’ use of resources (use behaviors) including work process requirements, ability to fulfill agency missions, new and possibly unfamiliar high-efficiency/high-performance building technologies; a lack of understanding, education, and training; inaccessible information or ineffective feedback mechanisms; and cultural norms and institutional rules and requirements, among others. While many strategies have been used to introduce new occupant use behaviors that promote sustainability and reduced resource consumption, few have been verified in the scientific literature or have properly documented case study results. This paper documents validated strategies that have been shown to encourage new use behaviors that can result in significant, persistent, and measureable reductions in resource consumption. From the peer-reviewed literature, the paper identifies relevant strategies for Federal facilities and commercial buildings that focus on the individual, groups of individuals (e.g., work groups), and institutions — their policies, requirements, and culture. The paper documents methods with evidence of success in changing use behaviors and enabling occupants to effectively interact with new technologies/designs. It also provides a case study of the strategies used at a Federal facility — Fort Carson, Colorado. The paper documents gaps in the current literature and approaches, and provides topics for future research.

    Increased international attention to water resource management has resulted in the creation of new institutional arrangements and funding mechanisms as well as international initiatives designed to strengthen river basin institutions. The Global Environment Facility's (GEF) International Waters Program is at the heart of such novel collaborative regional approaches to the management of transboundary water resources. This paper assesses GEF-led efforts in the Danube River Basin, GEF's most mature and ambitious projects to date. It finds that GEF has been quite successful in building scientific knowledge and strengthening regional governance bodies. However, challenges of coordinating across expanding participants and demonstrating clear ecological improvements remain. GEF-led collaborative activities in the Danube River Basin reveal three critical lessons that can inform future river basin institution building and decision making, including the importance of appropriately creating and disseminating scientific data pertaining to the river system, the need for regional governance bodies for integrated river basin management, and the necessity to address coordination issues throughout project planning and implementation.

    Full Text Available The visionary idea of BRIC1 countries and their leading position in the development of globaleconomy, conceived by the leading investment bank Goldman Sachs more than a decade ago, cameunder heavy skepticism. However, what many doubted came true. At the end of 2011 BRIC countriesgenerated approximately 26% of global GDP, and their share in the growth of global GDP was morethan 50%. The impressive growth of BRIC countries has been in large measure due to FDI inflow2.Intensive FDI inflow and economic development have not been followed by improved institutionalefficiency. This article will show that inefficient institutions in BRIC countries have not beendiscouraging to MNCs3, who were predominantly led by the extent and the growth dynamics of themarket. Modifications to business strategies applied in developed countries by MNCs, in order tomanage unstable institutional environment in BRIC countries, will be analyzed. The conclusion isthat the key modification is establishment of strong relationships with local stakeholders, in order forMNCs to gain necessary knowledge of the new business environment and create a sound basis forinstitutional efficiency improvement.

    Full Text Available The changes that are happening in businesses dictate the changes in all kinds of needed resources to develop the organization. The environment in which the organizations operate is in constant change and becomes more and more unpredictable. Managing these changes is a challenge that all enterprises face. The rapid changes that are happening in business are increasing the need to manage these changes. Enterprises have to develop and use different kinds of management models so that they can grow their performance in order to ensure a competitive position in the market. The changes in enterprises sometimes are not accepted by the organization employees, and seem to have negative effects towards them (exemption from work, reduction of working hours, reduction of income. Changes have negative and positive effects. Successful and rational managers can achieve having successful changes and minimizing the negative effects that come due to changes. Changes are vital for organizations so that they can replace the old plans and models with new and successful ones. In this paper we talk about the role and importance of managing the changes, the types of changes, models of changes, the resistance against changes and also the obtained results of the paper are introduced. Literature was used to support the research in the study field, and based on that to explain the role of changes in the business environment. There are quantitative methods and an inductive analysis used in this paper.

    2011-03-01

    Full Text Available Preparing for change is increasingly core business for governmental organizations. The networked society and the increasing connectedness of governmental organizations have as much impact on the complexity of the change process as the complexities of the corpus of law. Change is not only driven by changes in the law; changes in the organization’s environment often create a need to redesign business processes, reallocate roles and responsibilities, and reorder tasks. Moreover, preparations for change are not limited to the internal processes and systems of these organizations. Propagation of changes to network partners and redesign of network arrangements can be an enormous challenge. In the AGILE project, we develop a design method, distributed service architecture, and supporting tools that enable organizations - administrative and otherwise - to orchestrate their law-based services in a networked environment. This paper explains the Agile approach and describes some of its key principles.

  14. Rural local institutions and climate change adaptation in forest communities in Cameroon

    H. Carolyn Peach Brown

    2015-06-01

    Full Text Available Surveys and interviews were used to understand community resilience in forest-dependent communities facing climate change in Cameroon. Surveys of 232 individuals showed a diversity of formal and informal institutions that relate to most aspects of rural life. Although direct activities related to climate change adaptation were limited, the activities and density of membership in rural local institutions could increase the community's adaptive capacity. Twenty-six semistructured interviews were also conducted with representatives of diverse local institutions who had some responsibility for agriculture, forests, conservation, or development. Local governmental institutions had not received any information from the national level and were limited in their knowledge of how to help communities respond to climate change. Although limited in their direct action on climate change, local nongovernmental organizations and international institutions act as bridging institutions with rural communities and could facilitate sharing of knowledge and innovation, thereby fostering resilience. Planning for climate change adaptation in Cameroon needs to build the capacity of diverse local institutions and improve the relationships between local and national-level adaptation planning.

    2015-03-01

    This article studies the influence of local knowledge on the impact of science on institutional change in ecological and environmental management. Based on an empirical study on desertification control in 12 counties in north China, the study found the following major results: (1) although there was a cubic relationship between the extent and effect of local knowledge, local knowledge significantly influenced the impact of science on institutional change; (2) local knowledge took effect mainly through affecting formal laws and regulations, major actors, and methods of desertification control in institutional change but had no significant impact on the types of property rights; and (3) local knowledge enhanced the impact of science on the results of desertification control through affecting the impact of science on institutional change. These findings provide a reference for researchers, policy makers, and practitioners, both in China and in other regions of the world, to further explore the influence of local knowledge on the impact of science on institutional change and the roles of local knowledge or knowledge in institutional change and governance.

  2. Origins of institutional change: Brazilian alcohol fuel program between 1975 and 2000

    Energy Technology Data Exchange (ETDEWEB)

    Ollinaho, O.I.

    2012-07-01

    In this dissertation, I study the origins of institutional change. In organizational institutionalism institutional change is seen as being triggered either by exogenous shocks or by endogenous factors. I propose to see the origins of change instead through the dichotomy of cognitive versus material. One rationale for this is that, when addressing more broadly dispersed societal practices, the distinction between endogenous and exogenous loses its meaning. Another reason is that without taking materiality into account in a more comprehensive manner, institutional theory is toothless against the vast material fluxes that human activity, patterned as established practices, produces and consumes. Human activity is transforming the very basis of its foundation: raw material sources, ecosystems and even the climate of the planet. Not only does human activity have an impact on the planet, but the materiality in which we live, has its impact on our activity. I argue that changes in materiality affect our habitualized activities depending on how these changes are produced. This setting requires a more comprehensive relating of material and cognitive processes, something that I attempt to elucidate in this dissertation. I ground my conceptual development in the German sociology of knowledge, foremost in the writings of Alfred Schuetz and Thomas Luckmann. Established practices related to fossil fuels are central with regard to the adverse impacts of human activity. I study arguably the most successful attempt to deviate from these patterns: Proalcool. This ambitious Brazilian biofuel program was launched in 1975. Although alcohol was generally argued to be the definitive Brazilian solution and alcohol cars dominated the scene in the 1980s, by the end of the 1990s the program had lost its legitimacy and was seen as baggage to be done away with. I reconstruct the evolution of the program from 1975 to 2000 as a detailed narrative based on some 4000 news articles published in a

    Full Text Available The paper discusses the potential of action research to meet the challenges entailed in institutional design for urban water management. Our overall aim is to briefly present action research and discuss its methodological merits with regard to the challenges posed by the different conceptual bases for extrapolating the effects of institutional design on institutional change. Thus, our aim is to explore how Action Research meets the challenge of scoping the field in an open fashion for determining the appropriate mechanisms of institutional change and supporting the emerging of new water institutions. To accomplish this aim, we select the Water Framework Directive (WFD as an illustrative driving force requiring changes in water management practices and implying the need for the emergence of new institutions. We employ a case of urban water management in the Volos Metropolitan Area, part of the Thessaly region in Greece, where a Pilot River Basin Plan was implemented. By applying action research and being involved in a long process of interaction between stakeholders, we examine the emergence of new institutions dealing with urban water management under the general principles of the major driving force for change: the WFD.

    Full Text Available The father of modern management, Peter Drucker, concluded that “We are in one of those great historical periods that occur every 200 ore 300 years when people don’t understand the world anymore, and the past is not sufficient to explain the future”. We think that organizational culture is equal to quality management. At the same time, we think that quality management is determinant in the organizational performance. If management understands the preferred corporate culture of its organization, it can take steps to create or maintain that culture. Importantly, the people-management policies and procedures should be adjusted to align with and support the desired culture. Eventually, the competition for capital in the banking sectors will increase. This will push banks to look for ways to improve ROE or share price, depending on the markets. In other markets, this has led banks to get into risk areas that are not well understood by many, leading to losses. Our research also highlights an important potential competitive advantage for banks in the region. Increasing creativity should lead to new business opportunities. Creating a culture of creativity in banks in the region would be a challenging. Changing organizational culture is a challenging process and should not be influenced only by external environmental factors or the decision-making of the management, strengthening the organizational culture should be a process that must involve the entire organization by taking into account the preferred culture that is affected by local cultures and environmental changes.

    The change of frozen soil environment is evaluated by permafrost thermal stability, thermal thaw sensibility and surface landscape stability and the quantitatively evaluating model of frozen soil environment is proposed in this paper. The evaluating model of frozen soil environment is calculated by 28 ground temperature measurements along Qinghai-Xizang Highway. The relationships of thermal thaw sensibility and freezing and thawing processes and seasonally thawing depth, thermal stability and permafrost table temperature, mean annual ground temperature and seasonally thawing depth, and surface landscape stability and freezing and thawing hazards and their forming possibility are analyzed. The results show that thermal stability, thermal thaw sensibility and surface landscape stability can be used to evaluate and predict the change of frozen soil environment under human engineering action.

    Over the past decade or so the evolution and equilibria of persistent decks of stratocumulus climatologically clinging to the edge of summertime subtropical highs has been an issue of increased scientific inquiry. The particular interest in the microphysical structure of these clouds stems from a variety of hypotheses which suggest that anthropogenic influences or biogenic feedbacks may alter the structure of these clouds in a manner which may be climatically significant. Most hypotheses regarding boundary layer influences on climate have been formulated by an examination of the solution space of simple models. The earliest hypothesis of this sort (and the one on the most solid footing) is due to Twomey (1974), who posited that enhanced concentrations of CCN could lead to enhanced droplet reflectivity and enhanced albedos in clouds of modest optical depths. In low lying clouds where the albedo effect dominates, the climate sensitivity to a robust perturbation in cloud albedo may be significant. One of the primary objectives of this current research has been to explore the hypothesis of Twomey. The basic approach was to couple radiative calculations with detailed representations of the droplet spectra. The detailed representation of the droplet spectra was generated by the Large Eddy Simulation-Explicit Microphysics (LES-EM) model coupled to a simple mixed emissivity radiation scheme in order to drive the dynamics. Several simulations were carried out and the resultant microphysical fields were taken from the stationary regime of the turbulent simulation and used to drive a two dimensional radiative model. By comparing the radiative properties of the simulated clouds formed in environments with different CCN concentrations we were able to more accurately quantify the albedo susceptibility of stratocumulus taken to be typical of the FIRE experimental area.

  9. Vegetation change in dryland environments: understanding changes in fluvial fluxes via changes in hydrological connectivity

    Dryland environments are estimated to cover around 40% of the global land surface (Okin et al, 2009) and are home to approximately 2.5 billion people (Reynolds et al. 2007). Many of these areas have recently experienced extensive land degradation. One such area and the focus of this project is the semi-arid US Southwest, where degradation over the past 150 years has been characterised by the invasion of woody vegetation into grasslands. The transition from grass to woody vegetation results in a change in ecosystem structure and function (Turnbull et al, 2008). Structural change is typically characterised by an increased heterogeneity of soil and vegetation resources, associated with reduced vegetation coverage. Functional change is characterised by an increased vulnerability to soil erosion and the potential loss of key nutrients to adjacent fluvial systems. Such loss of resources may impact heavily upon the amount of carbon that is sequestered by these environments and the amount of carbon that is lost as the land becomes more degraded. Therefore, understanding these vegetation transitions is significant for sustainable land use and global biogeochemical cycling. Connectivity is a key concept in understanding the hydrological response to this vegetation change, with reduced vegetation coverage in woody environments being associated with longer and more connected overland flow pathways. This increase in hydrological connectivity results in an accentuated rainfall-runoff response and increased fluvial fluxes of eroded sediment and associated soil organic carbon and other nutrients. This project uses an ecohydrological approach, characterising ecological structure and monitoring natural rainfall-runoff events over bounded plots with different vegetation covering the transitions from C4 pure-grass (Bouteloua eriopoda) to C3 creosote (Larrea tridentate) shrubland and C3 piñon-juniper (Pinus edulis-Juniperus monosperma) mixed stand woodland.

    McDermott, Christa; Malone, Elizabeth L.

    2014-05-20

    This report assesses the use of institutional change principles and the institutional impact of award-winning projects through interviews with 22 Department of Energy Federal Energy Management Program (DOE FEMP) award winners. Award winners identified institutional facilitators and barriers in their projects and programs as well as factors in their implementation processes, thus providing information that can guide other efforts. We found that award winners do use strategies based on eight principles of institutional change, most frequently in terms of making changes to infrastructure, engaging leadership, and capitalizing on multiple motivations for making an energy efficiency improvement. The principles drawn on the least often were commitment and social empowerment. Award winners also faced five major types of obstacles that were institutional in nature: lack of resources, constraints of rules, psychological barriers, lack of information, and communication problems. We also used the seven categories of Energy Management Excellence (EME) as a lens to interpret the interview data and assess whether these categories relate to established institutional change principles. We found that the eight principles reflect strategies that have been found to be useful in improving energy efficiency in organizations, whereas the EME categories capture more of a blend of social contextual factors and strategies. The EME categories fill in some of the social context gaps that facilitate institutional change and energy management excellence, for example, personal persistence, a culture that supports creativity and innovation, regular engagement with tenants, contractors, and staff at all levels. Taking together the use of principles, EME criteria, and obstacles faced by interviewees, we make recommendations for how FEMP can better foster institutional change in federal agencies.

    Full Text Available Businesses and governments choose how they wish to deal with change. Whether this change is organizational, technological, political, financial etc or even individual pursuing actions as usual is likely to lead to a downward path. The authors of this paper are giving a set of tools for confronting and understanding the consequences of this era of permanent changes by building strengths and seeking opportunities within organizations (private or public and within family (including friends. The work environment and the personal life of the individual have a common point which is adaptability, coping efficiently with changes, a demanded ability of the 3rd millennium human being.

  14. Continuity and Change in Social-ecological Systems: the Role of Institutional Resilience

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available In recent years recurring political, economic, and environmental crises require questioning and re-evaluating dominant pathways of human development. However, political and economic frameworks seem to encompass deeply rooted resistance to fundamental changes (e.g., global financial crisis, climate change negotiations. In an effort to repair the system as fast as possible, those paradigms, mechanisms, and structures that led into the crisis are perpetuated. Instead of preserving conventional patterns and focusing on continuity, crises could be used as an opportunity for learning, adapting, and entering onto more sustainable pathways. However, there are different ways not only of arguing for sustainable pathways of development but also of conceptualizing continuity and change. By focusing on institutions, we illustrate the tension between the concepts of continuity and change, how they interact, and how they build or degrade institutional resilience. The analysis draws on empirical research in South Africa and Uzbekistan, which were locked in persistent regimes over decades. Faced with the challenge to transform, Uzbekistan chose a pathway of institutional continuity, while South Africa opted for comprehensive reforms and a high level of change. Based on these case studies, we illustrate the advantages and disadvantages of institutional continuity and change. Elements of institutional continuity during times of transformation include preserving key institutions, which define how the rules are made; maintaining social memory; providing transparency of reform processes and allowing them time to take effect. Elements of institutional change required during phases of consolidation include flexible legislation; regular reviews; and adaptation of legislation during and after implementation.

  15. 1988 Pilot Institute on Global Change on trace gases and the biosphere

    1998-07-01

    This proposal seeks multi-agency funding to conduct an international, multidisciplinary 1988 Pilot Institute on Global Change to take place from August 7 through 21, 1988, on the topic: Trace Gases and the Biosphere. The institute, to be held in Snowmass, Colorado, is envisioned as a pilot version of a continuing series of institutes on Global Change (IGC). This proposal seeks support for the 1988 pilot institute only. The concept and structure for the continuing series, and the definition of the 1988 pilot institute, were developed at an intensive and multidisciplinary Summer Institute Planning Meeting in Boulder, Colorado, on August 24--25, 1987. The theme for the 1988 PIGC, Trace Gases and the Biosphere, will focus a concerted, high-level multidisciplinary effort on a scientific problem central to the Global Change Program. Dramatic year-to-year increases in the global concentrations of radiatively-active trace gases such as methane and carbon dioxide are now well documented. The predicted climatic effects of these changes lend special urgency to efforts to study the biospheric sources and sinks of these gases and to clarify their interactions and role in the geosphere-biosphere system.

  16. Social change, institutional anomie, and serious property crime in transitional Russia.

    Kim, Sang-Weon; Pridemore, William Alex

    2005-01-01

    This study examined socioeconomic change, social institutions, and serious property crime in transitional Russia. Durkheim's anomie theory and recent research on violence in Russia led us to expect an association between negative socioeconomic change and property crime. Based upon institutional anomie theory, we also tested the hypothesis that the association between change and crime is conditioned by the strength of non-economic social institutions. Using crime data from the Russian Ministry of the Interior and an index of socioeconomic change, we used OLS regression to estimate cross-sectional models using the Russian regions (n=78) as the unit of analysis. Results surprisingly showed no effect of socioeconomic change on two different measures of robbery, only very limited support for the hypothesis of direct effects of social institutions on crime, and obviously no support for the hypothesis that institutions moderate the effect of change on crime. We interpret these findings in the context of transitional Russia and conclude that rigorous research in other nations is important in determining the generalizability of criminological theories developed to explain crime in Western nations.

I present an empirical paper focusing on transition of the Polish Economy. I used a questionnaire which was administered to a sample of about 1000 Polish firms in order to verify the impact of economic institutions on the "residual productivity". Throughout the questionnaire I built six governance indexes. Then I tested the impact of the governance indexes on the productivity of firms. I observed that the economic performance of the eastern regions of Poland, where governance indexes are worse than western, are poorer than that of the western regions of Poland

  7. Petroleum privatization and institutional environment: the Russian example; Privatisation petroliere et environnement institutionnel: l'exemple russe

    Energy Technology Data Exchange (ETDEWEB)

    Locarelli, C.; Finon, D

    2003-09-01

    This paper treats of the reform of the Russian hydrocarbons industry using an institutionalistic approach. The theoretical objective of the privatization is the installation of a growth scheme based on important productivity gains, through large scale re-structuration, investments for the reproduction of oil and gas reserves, and big infrastructures development. The choice of this sector is justified because it represents an extreme case of inadequateness of the measures preconized by the Washington consensus with respect to the institutional environment. Stress has been put on the modification of the property rights of companies. The introduction of market institutions in a transition economy has led to an opportunistic adaptation of the behaviour of private and government actors. There is a clear correlation between the insecurity of property rights in general and the abundance of exploitable and exportable natural resources. Then, the privatization and the limited performance of the hydrocarbons sector in Russia is analyzed in terms of efficiency and long-term strategy, essential for a resources industry to make reserves. The unexpected results of this privatization are explained using an analysis of the market institutions applied to the very specific institutional environment of the Russian economy. Finally, the inadequateness of these institutions with the initial informal institutions has led to adaptations fully dependent of the institutional path with the necessity of preserving a minimum inter-industrial consistency.

    Terrestrial as well as extraterrestrial satellite data and environmental parameter records were correlated. It has been observed that some relationship exists in between the changes in environment and extraterrestrial phenomenon. The star flare changes the cosmic parameters. The nearest star of earth, the Sun, is found to be under the influence of the star flare. It has been observed that there is some relationship in between the planetary indices (Kp) Electron flux (E flux) Proton flux (P-flux) of Sun-Earth environment with the changes in thermosphere, ionosphere, atmosphere and geosphere. The tsunami of 26 December 2004, abnormal snowfall in 2004-2005, sudden hike in global temperature and erratic monsoon in India and irregular rainfall in other parts of the world in 2006-2007 followed by snowfall and torrential rain are the impact of the star-sun-earth relationship.

  10. DO REALLY EMPLOYEES RESIST CHANGE? CASE STUDY AT A CREDIT INSTITUTION

    Directory of Open Access Journals (Sweden)

    DANIELA BRADUTANU

    2012-05-01

    Full Text Available Organizational management literature describes resistance to change as an impediment, an inevitable and natural reaction to change. The purpose of this study is to show that employees do not always resist change, at least not change per se. We have conducted a survey in a credit institution that underwent a major change in the last few years. Data was collected using questionnaires, interviews with managers and other employees and direct observation. The objectives of the study are to identify the real reasons why employees resist change, what is the outcome expectation of the change process and if the employees support the change process. Some researchers argue that top management usually opposes the new changes, while others confute these statements. The identified results show that few employees resist change, willingness to change being the general response in the organization.

  12. Anticipating Changing in Environments: Adaptation in Fluctuating Environments in A Heterogeneous Microbial Communites

    Science.gov (United States)

    Belete, Merzu; Bálazsi, Gábor

    2015-03-01

    The environments in which micro-organisms grow often fluctuate. To survive in temporally changing environments, cells have evolved mechanisms to survive environmental changes. One survival mechanism is generating phenotypic differences among identical cells in a given environment, with cells randomly switching between phenotypes. Such cells form subpopulations that proliferate at different rates. Optimal population fitness was attributed before to matching cellular and environmental switching rates. However, the conditions for this optimum are not well understood. In particular, it is unknown how the growth rates of the phenotypes affect the optimum. We use mathematical models to address this question. We find that the existence of the predicted optimum depends on cell growth rates in each phenotype. The predicted optimum exists for wider parameter regimes if the environmental durations are long. In addition, we study how mutants arising among such phenotypically heterogeneous cells spread in the population.

    Emotional responses to biologically significant events are essential for human survival. Do human emotions lawfully track changes in the acoustic environment? Here we report that changes in acoustic attributes that are well known to interact with human emotions in speech and music also trigger systematic emotional responses when they occur in environmental sounds, including sounds of human actions, animal calls, machinery, or natural phenomena, such as wind and rain. Three changes in acoustic attributes known to signal emotional states in speech and music were imposed upon 24 environmental sounds. Evaluations of stimuli indicated that human emotions track such changes in environmental sounds just as they do for speech and music. Such changes not only influenced evaluations of the sounds themselves, they also affected the way accompanying facial expressions were interpreted emotionally. The findings illustrate that human emotions are highly attuned to changes in the acoustic environment, and reignite a discussion of Charles Darwin's hypothesis that speech and music originated from a common emotional signal system based on the imitation and modification of environmental sounds.

    When grand institutional reforms based on idealized models are stalled by the poor institutional environments and difficult politics which often surround large infrastructure systems in developing countries, partial reforms whose design and implementation take into account the different interests of the key stakeholders can provide valuable and immediate benefits while moving these systems from low- towards higher-level equilibria. Strategically negotiated, experimentally partial and purposefully hybrid, these reforms are based on careful stakeholder analysis and strategic coalition building that avoid rigid positions based on idealized models. Our findings are based on a study of power sector reforms in India, where we performed a micro-level and in-depth analysis of a partial and innovative experiment which has allowed private sector participation in electricity distribution within a hostile institutional environment.

    One aspect of intelligence is the ability to restructure your own environment so that the world you live in becomes more beneficial to you. In this paper we investigate how the information-theoretic measure of agent empowerment can provide a task-independent, intrinsic motivation to restructure the world. We show how changes in embodiment and in the environment change the resulting behaviour of the agent and the artefacts left in the world. For this purpose, we introduce an approximation of the established empowerment formalism based on sparse sampling, which is simpler and significantly faster to compute for deterministic dynamics. Sparse sampling also introduces a degree of randomness into the decision making process, which turns out to beneficial for some cases. We then utilize the measure to generate agent behaviour for different agent embodiments in a Minecraft-inspired three dimensional block world. The paradigmatic results demonstrate that empowerment can be used as a suitable generic intrinsic motivation to not only generate actions in given static environments, as shown in the past, but also to modify existing environmental conditions. In doing so, the emerging strategies to modify an agent's environment turn out to be meaningful to the specific agent capabilities, i.e., de facto to its embodiment.

    Full Text Available Baldwin’s synthesis of the Organicist position, first published in 1896 and elaborated in 1902, sought to rescue environmentally induced phenotypes from disrepute by showing their Darwinian significance. Of particular interest to Baldwin was plasticity’s mediating role during environmental change or colonization—plastic individuals were more likely to successfully survive and reproduce in new environments than were nonplastic individuals. Once a population of plastic individuals had become established, plasticity could further mediate the future course of evolution. The evidence for plasticity-mediated persistence (PMP is reviewed here with a particular focus on evolutionary rescue experiments, studies on invasive success, and the role of learning in survival. Many PMP studies are methodologically limited, showing that preexistent plasticity has utility in new environments (soft PMP rather than directly demonstrating that plasticity is responsible for persistence (hard PMP. An ideal PMP study would be able to demonstrate that (1 plasticity preexisted environmental change, (2 plasticity was fortuitously beneficial in the new environment, (3 plasticity was responsible for individual persistence in the new environment, and (4 plasticity was responsible for population persistence in succeeding generations. Although PMP is not ubiquitous, Baldwin’s hypotheses have been largely vindicated in theoretical and empirical studies, but much work remains.

  20. Selection, adaptation, and predictive information in changing environments

    Feltgen, Quentin; Nemenman, Ilya

    2014-03-01

    Adaptation by means of natural selection is a key concept in evolutionary biology. Individuals better matched to the surrounding environment outcompete the others. This increases the fraction of the better adapted individuals in the population, and hence increases its collective fitness. Adaptation is also prominent on the physiological scale in neuroscience and cell biology. There each individual infers properties of the environment and changes to become individually better, improving the overall population as well. Traditionally, these two notions of adaption have been considered distinct. Here we argue that both types of adaptation result in the same population growth in a broad class of analytically tractable population dynamics models in temporally changing environments. In particular, both types of adaptation lead to subextensive corrections to the population growth rates. These corrections are nearly universal and are equal to the predictive information in the environment time series, which is also the characterization of the time series complexity. This work has been supported by the James S. McDonnell Foundation.

    Natural sounds such as wind or rain, are characterized by the statistical occurrence of their constituents. Despite their complexity, listeners readily detect changes in these contexts. We here address the neural basis of statistical decision-making using a combination of psychophysics, EEG and modelling. In a texture-based, change-detection paradigm, human performance and reaction times improved with longer pre-change exposure, consistent with improved estimation of baseline statistics. Change-locked and decision-related EEG responses were found in a centro-parietal scalp location, whose slope depended on change size, consistent with sensory evidence accumulation. The potential's amplitude scaled with the duration of pre-change exposure, suggesting a time-dependent decision threshold. Auditory cortex-related potentials showed no response to the change. A dual timescale, statistical estimation model accounted for subjects' performance. Furthermore, a decision-augmented auditory cortex model accounted for performance and reaction times, suggesting that the primary cortical representation requires little post-processing to enable change-detection in complex acoustic environments.

    Full Text Available Problem statement: The objective of this research was to study the environment change of Lampao Dam communities in Northeast Thailand, being a case study of the Sa-Adnathom community, Lamklong sub-district, Muang, Kalasin province, adjacent to the Lampao Dam. Approach: A qualitative research, it started with a review of literature and related researches. Field data were collected by way of interviews and both participant and non-participant observations, involving 15 informants including senior-villagers, who had lived in the village some 10-20 years. The research data were descriptively analyzed and presented. Results: As a result its was found that the Lampao Dam communities date back 200 years to the era of Chiangsom Kingdom. Deserted due to deadly epidemics, the area was later on repopulated by migrants from Yang Talad district, Kalasin province. A new community, called Sa-Adnathom, was born. Prior to the inception of the National Plan for Social and Economic Development in 1961, the environment of this community was complete with fertile land and natural resource abundance. People lived in harmony with nature and relied on resources from it for their livelihood, especially from Nong Waeng reservoir, Phan and Yang streams and Khoke Ngoo forest. But with the implementation of the first Plan for Social and Economic Development in 1961-1966 the Thai government started the construction of the Lampao Dam in 1963. Completed in 1968, the Dam took land from the villagers, part of which were simply flooded. This forced the village farmers to change their means of livelihood from relying on forest and rivers to production methods which by necessity involved purchase of machines and usage of chemical fertilizers. In short, a change from farming to fishing in Lampao Dam. Their values also changed from local exchanges of goods to money economy, which only led to household debts, increasing with rising degree of consumerism. Eventually people in the

Recent research has paid growing attention to the role of policy networks-the actors involved in policy-making, their relationships with each other, and the structure formed by those relationships-in policy reform across settings and issues; however, this literature has largely ignored the theoretical integration of networks with other policy theories, including the '3Is' of institutions, interests and ideas. This article proposes a conceptual framework integrating these variables and tests it on three cases of policy change in Burkina Faso, addressing the need for theoretical integration with networks as well as the broader aim of theory-driven health policy analysis research in low- and middle-income countries. We use historical process tracing, a type of comparative case study, to interpret and compare documents and in-depth interview data within and between cases. We found that while network changes were indeed associated with policy reform, this relationship was mediated by one or more of institutions, interests and ideas. In a context of high donor dependency, new donor rules affected the composition and structure of actors in the networks, which enabled the entry and dissemination of new ideas and shifts in the overall balance of interest power ultimately leading to policy change. The case of strategic networking occurred in only one case, by civil society actors, suggesting that network change is rarely the spark that initiates the process towards policy change. This analysis highlights the important role of changes in institutions and ideas to drive policymaking, but hints that network change is a necessary intermediate step in these processes.

    2010-11-01

    Full Text Available The evolution of the energy market and the intrinsic worldwide scope of environmental threats, such as climate change, are two elements that have pushed the world towards shared approaches to global governance via bilateral institutions and international regimes. This article, with the aid of an institutionalist approach, presents the current status of the EU-China relationship, which is characterised by high institutionalisation, and it underlines how their bilateral cooperation has progressively focused on energy and climate change-related issues. In particular, the article sheds some light on the linkages between energy, environment and climate change and how these have created the basis for the upgrade of the EU-China bilateral relationship to its current level. To do so, it underlines some of the tools, the main frameworks and some of the key outcomes of their bilateral cooperation in these fields.

    Full Text Available The Tibetan grassland social-ecological systems are widely held to be highly vulnerable to climate change. We aim to investigate livelihood adaptation strategies of herder households and the types of local institutions that shaped those adaptation strategies. We examined the barriers and opportunities for strengthening adaptive capacity of local herder communities. We designed and implemented a household survey in the herder communities of northern Tibet. The survey results showed that migratory grazing has become less feasible. Storage, diversification, and market exchange have become the dominant adaptation strategies. The adaptation strategies of local herders have been reshaped by local institutional change. Local governmental and market institutions played the dominant roles in reshaping climate adaptation strategies. Although the present livelihood adaption strategies related to sedentary grazing have improved productivity and profitability of the herding livelihood, they have led to continuous deterioration of pastures. The local grazing system has become more and more dependent on artificial feeding and inputs from outside the grazing system. Purchasing forage has become one of the dominant adaptation strategies of local herder households. Multilevel regression modeling of this adaptation behavior showed that explanatory variables related to climate variability, household capital, and local institutional arrangements had statistically significant relationships with the adoption of this adaptation strategy. The results implies that building household capital and promoting the coordination among local governmental, market, and communal institutions are critical for strengthening adaptive capacity of the Tibetan herder communities.

    2010-09-01

    In this study, we examined changes in the early home learning environment as children approached school entry and whether these changes predicted the development of children's language and academic skills. Findings from a national sample of the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (N = 1,018) revealed an overall improvement in the home learning environment from 36 to 54 months of children's age, with 30.6% of parents of preschoolers displaying significant improvement in the home environment (i.e., changes greater than 1 SD) and with only 0.6% showing a decrease. More important, the degree of change uniquely contributed to the children's language but not to their academic skills. Home changes were more likely to be observed from mothers with more education and work hours and with fewer symptoms of depression.

    2009-07-28

    One of the most pressing and globally recognized challenges is how to mitigate the effects of global environment change brought about by increasing emissions of greenhouse gases, especially CO(2). In this review we evaluate the potential contribution of four biological approaches to mitigating global environment change: reducing atmospheric CO(2) concentrations through soil carbon sequestration and afforestation; reducing predicted increases in global surface temperatures through increasing the albedo of crop plants; and fertilizing the oceans to increase primary productivity and CO(2) drawdown. We conclude that none of these biological approaches are 'magic bullets' capable of reversing environmental changes brought about by increasing emissions of greenhouse gases. However, it is possible that increasing crop albedo and soil carbon sequestration might contribute towards mitigation on a regional scale. In the absence of legally binding international agreements to reduce CO(2) emissions, we propose that: increased efforts are made to identify novel biological mitigatory strategies; further research is conducted to minimise the uncertainties present in all four of the biological approaches described; and pilot-level field work is conducted to examine the feasibility of the most promising strategies. Finally, it is essential to engage with the public concerning strategies for mitigating the effects of climate change because the majority of the biological approaches have effects, quite possibly of a negative nature, on ecosystem services and land usage.

    2003-03-01

    Full Text Available The purpose of a thought experiment, as the term was used by quantum and relativity physicists in the early part of the twentieth century, was not prediction (as is the goal of classical experimental science, but more defensible representations of present ‘realities’. Speculative fictions, from Mary Shelley's Frankenstein to the Star Wars cinema saga, can be read as sociotechnical thought experiments that produce alternative representations of present circumstances and uncertainties, and anticipate and critique possible futures. In this essay I demonstrate how two examples of popular speculative fictions, Frank Herbert's Dune (1965 and Ursula Le Guin's The Telling (2000, function as thought experiments that problematise global transitions in their respective eras. I argue that critical readings of such stories can help us to anticipate, critique, and respond constructively to social and cultural changes and change environments within nation-states that constitute, and are constituted by, global change processes and their effects.

    Full Text Available In the article, the effect of interaction between the development level of regional innovative capacity and its innovative and institutional infrastructure is traced. The research objective is to prove the hypothesis of the essential impact of the regional institutional and information environment on its innovative capacity, the identification of the effect of their systemsupplementing interaction. From the standpoint of the methodology of system-structural research its components are allocated within the innovative capacity of the regional innovative system (RIS, they are presented by a corporate sector, the structures of small and medium business, and also by the subjects of ethnic economy. The use of essential-analytical and functional approaches has revealed the leading role of intangible assets of the corporate sector of the economy in region’s innovative development. The correlation and regression analysis has confirmed the essential dependence of the innovative activity of the region on the systemic completeness of the development of its institutional and infrastructure environment. The results of the research have shown that to ensure the system-supplementing effect of the interaction between innovative capacity and the factors of its activation in the sphere of institutional infrastructure, it is necessary to consistently develop its operational base — the institutions of RIS. The recommendations reasoned in the article may be used for the development of regional innovation strategies, the formation of innovation clusters. The three-component structure of the innovation cluster of the region is offered; its integrating function in relation to the innovative components of the regional sectoral clusters is determined. The factors constraining the growth of innovation activity of the regional economic subjects are revealed and the recommendations on the development of the institutional and infrastructural environment of the Rostov

    Smith, Stephen L; Rus, Daniela

    2011-01-01

    We present controllers that enable mobile robots to persistently monitor or sweep a changing environment. The changing environment is modeled as a field which grows in locations that are not within range of a robot, and decreases in locations that are within range of a robot. We assume that the robots travel on given closed paths. The speed of each robot along its path is controlled to prevent the field from growing unbounded at any location. We consider the space of speed controllers that can be parametrized by a finite set of basis functions. For a single robot, we develop a linear program that is guaranteed to compute a speed controller in this space to keep the field bounded, if such a controller exists. Another linear program is then derived whose solution is the speed controller that minimizes the maximum field value over the environment. We extend our linear program formulation to develop a multi-robot controller that keeps the field bounded. The multi-robot controller has the unique feature that it do...

    Full Text Available Abstract Background The family food environment is an important influence in the development of children’s dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1 investigate the association between the food environment at baseline and change in children’s saturated fat intake; and (2 to explore whether a change in the food environment was associated with a change in children’s saturated fat intake. Method Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment – Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children’s dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (p Results After adjustments for child and family demographics, higher levels of perceived food availability (β=-0.2 at baseline was associated with greater reduction in saturated fat intake, where as higher perceived responsibility (β=0.2, restriction (β=0.3 and pressure to eat (β=0.3 were associated with lesser change in saturated fat.

    Nurse executives must take a leadership role in creating a healthy work environment for nurses and all disciplines. Engaging in partnerships and empowering clinical nurses to construct the solutions to barriers that may stand in the way of the goal of a satisfied and healthy workforce are important strategies toward success. This publication outlines many projects a 3-time Magnet-designated academic hospital has implemented, working with our shared leadership councils, to meet the standards for a healthy work environment. These initiatives, from the unit to the hospital level, included standardizing a culture change of uninterrupted meal breaks, the creation of intensive care unit Zen rooms, strategies to better manage increased patient volumes, best practices for facility design, enhancing physician-nurse relations, and a hospital wellness program. Data were benchmarked against national nurse and employee surveys to compare progress and report outcomes. Two important nursing organization structures that have contributed to the success of a healthy and satisfied nursing work environment include UEXCEL, a longstanding clinical nurse professional practice program, and the hospital's 11-year participation in the University HealthSystem Consortium/American Association of Colleges of Nursing National Post-Baccalaureate Nurse Residency Program. A highly engaged, well-educated, and committed nursing workforce, nurtured by a strong leadership team, has created a positive work environment characterized by low turnover and high retention.

    2013-01-01

    Full Text Available Consistent with the notion that the institutional environment affects entrepreneurialactivity, this article interrogates how a person’s willingnessto pursue social entrepreneurship is connected with self-efficacy beliefs.Hypotheses are formulated in terms of South Africa’s regulatory, normative,and cognitive institutional profiles relating to an individual’s socialentrepreneurship self-efficacy. Findings indicate favourable perceptionsof the regulatory and normative dimensions, which are associatedwith higher levels of self-efficacy. Implications imply that although institutionalsupport mechanisms are essential to increase social businesspractices, ultimately social entrepreneurship can only spread by fosteringindividual self-beliefs.

  1. Toward a transtheoretical model of interprofessional education: stages, processes and forces supporting institutional change.

    Clark, Phillip G

    2013-01-01

    The history of interprofessional education (IPE) in the USA is a checkered one, characterized by boom and bust cycles of advancement and retrenchment, expansion and contraction. The successful development, implementation and continuation of IPE in health and social care in US higher education institutions all depend on a number of factors related to how individuals and organizations do or do not support it in the academic setting. Deliberate and planned change to advance IPE requires a comprehensive theoretical framework to guide it and insure its success. A transtheoretical model (TTM) of institutional change is proposed as a comprehensive framework of the stages, processes and forces that can facilitate and maintain change in support of IPE. The TTM framework recognizes the complexity of change, and captures and organizes important elements from different organizational theories. It also provides a structure for conceptualizing the multiple dimensions needed for change, offering intervention strategies and leverage points to be used by leaders in promoting and maintaining it. Finally, the TTM model suggests that the stabilization of IPE programs over the long term is dependent on a real and significant shift in institutional values in response to forces from both within and without the organization.

  2. International financial institutions and health in Egypt and Tunisia: change or continuity?

    Science.gov (United States)

    Ismail, Sharif

    2013-01-01

    The revolutions in Egypt and Tunisia appeared to herald a re-casting of International Monetary Fund and World Bank policy across the region. Public pronouncements by the heads of both institutions in the months following February 2011 acknowledged flaws in their approach to macroeconomic advice, against a background of worsening socioeconomic indicators, widespread youth unemployment, and widening health inequalities. Evidence on the ground, however, suggests continuity rather than change in international financial institution policies in Egypt and Tunisia, notwithstanding the emergence of a powerful new player-the European Bank for Reconstruction and Development. In the long term, new electoral realities and hardening public opposition in both countries seem likely to force a fundamentally different relationship between regional governments and the major international financial institutions than existed before 2011.

    2009-04-15

    Over the course of 50 years, UK radioactive waste policy change has been coupled with institutional change, without much progress towards the ultimate goal of safe, long-term stewardship of wastes. We explain this history as a search for legitimacy against a shifting context of legitimation needs and deficits. Following Habermas, we argue that legitimation is derived from a process of justificatory discourse. In principle, there must be a reasonable exchange of arguments between diverse parties in society, based on common norms, for legitimacy to be achieved. We show that the work of legitimation in UK radioactive waste policy has moved from a focus on factual validity claims towards an increasing emphasis on deliberative processes. This reframing of legitimation needs explains institutional and policy changes in UK radioactive waste policy. The most recent phase of policy and institutional change, which placed public deliberation about long-term management and disposal options centre-stage, represents a new step towards bridging legitimation deficits. Plans to build new nuclear reactors in the UK based on a more closed 'streamlined' decision process risk reversing the legitimacy gains that have been achieved through growing openness on radioactive waste management.

  4. Power rather than path dependency? The dynamics of institutional change under health care federalism.

    Rico, Ana; Costa-Font, Joan

    2005-01-01

    Proposals for government decentralization rank high on the political reform agenda of health systems worldwide. Their impact on welfare state performance and change, however, is still under theoretical scrutiny. This article examines the impact of devolution on the construction of the Spanish National Health Service (NHS) in an attempt to shed some light on this debate. Against widespread claims of path dependency, we argue that the specific nature of the devolution model developed in Spain, given the more egalitarian sociopolitical structure that resulted from democratization, fostered policy innovation and institutional change. Consolidation of an NHS system was compatible with some regional diversity and apparently prevented the rise of significant territorial inequalities. The Spanish case also suggests that policy change depends more on the distribution of social power than on institutions. It underlines the key role of financial and knowledge transfers vis-à-vis institutional reforms in effecting social change as well as the potential for state intervention in supporting the development of collective action resources by social groups.

    2015-12-01

    The Earth Science cyberinfrastructure landscape is constantly changing. Technologies advance and technical implementations are refined or replaced. Data types, volumes, packaging, and use cases evolve. Scientific requirements emerge and mature. Standards shift while systems scale and adapt. In this complex and dynamic environment, interoperability remains a critical component of successful cyberinfrastructure. Through the resource- and priority-driven iterations on systems, interfaces, and content, questions fundamental to stable and useful Earth Science cyberinfrastructure arise. For instance, how are sociotechnical changes planned, tracked, and communicated? How should operational stability balance against 'new and shiny'? How can ongoing maintenance and mitigation of technical debt be managed in an often short-term resource environment? The Arctic Data Explorer is a metadata brokering application developed to enable discovery of international, interdisciplinary Arctic data across distributed repositories. Completely dependent on interoperable third party systems, the Arctic Data Explorer publicly launched in 2013 with an original 3000+ data records from four Arctic repositories. Since then the search has scaled to 25,000+ data records from thirteen repositories at the time of writing. In the final months of original project funding, priorities shift to lean operations with a strategic eye on the future. Here we present lessons learned from four years of Arctic Data Explorer design, development, communication, and maintenance work along with remaining questions and potential directions.

    2010-12-01

    Full Text Available The article distinguishes federal states from bicameralism and mechanisms of territorial representation in order to examine the association of each with institutional change in 32 countries by using constitutional amendments as a proxy. It reveals that bicameralism tends to be a better predictor of constitutional stability than federalism. All of the bicameral cases that are associated with high rates of constitutional amendment are also federal states, including Brazil, India, Austria, and Malaysia. In order to explore the mechanisms explaining this unexpected outcome, the article also examines the voting behavior of Brazilian senators constitutional amendments proposals (CAPs. It shows that the Brazilian Senate is a partisan Chamber. The article concludes that regional influence over institutional change can be substantially reduced, even under symmetrical bicameralism in which the Senate acts as a second veto arena, when party discipline prevails over the cohesion of regional representation.

Reference is made to a “political economic person” (PEP guided by her/his “ideological orientation” and “political economic organization” (PEO, guided by its “mission”. Leaving present unsustainable trends behind is a matter of politics and ideology and even power positions, where democracy plays a crucial role. The perspectives of influential (and other actors are essential in facilitating (or hindering change. I will discuss ideas of the role of science in society, mainstream neoclassical economics in relation to institutional economics in the spirit of K. William Kapp and Gunnar Myrdal as well as neo-liberalism as ideology (where neoclassical economics has contributed to strengthen the legitimacy of neo-liberalism. Various aspects of inertia and flexibility in institutional change processes, such as path dependence, are discussed. Emphasis is on the role of economics and how a strengthened democracy can open the door for a degree of pluralism.

    Neave, Mel; Rayburg, Scott

    2007-09-01

    The desertification of grassland communities in the Jornada del Muerto Basin, southern New Mexico, USA, has occurred in association with a series of geomorphic responses that have influenced the system of vegetation change. Rainfall simulation experiments indicate that the volume of runoff generated from basin surfaces and its ability to erode are greatly affected by the distribution of vegetation, which ultimately controls processes such as rainsplash erosion, soil infiltrability and crust development. Animal activities also influence rates of sediment movement from unvegetated surfaces by disrupting soil crusts and making loose sediment available for transportation by overland flow. Shrublands in the Jornada Basin have a patchier vegetation cover than grasslands, with vegetated areas (shrubs) being separated by unvegetated (intershrub) zones. The exposed intershrub surfaces are more vulnerable to erosion than the grass and shrub surfaces. Thus, water and sediment yields, calculated using rainfall simulation experiments, were higher for vegetated (shrub and grass) plots than they were for unvegetated (intershrub) plots. The runoff and erosion model, KINEROS2, predicts that at the base of a 100 m slope, shrubland surfaces shed seven times more runoff and 25 times more sediment than grassland surfaces. Evidence to support the prediction of higher rates of erosion in the shrubland can be found in the form of the extensive rill networks that are common in this community. The contraction of grasslands has been associated with elevated rates of erosion that have altered the morphology of the surface, lowering slopes between shrubs, and increasing the amplitude of the microtopography. Overall, the viability of the exposed soils for recolonization by grasses has been reduced, reinforcing the system of shrubland invasion and lending support to the use of state-and-transition models to describe ecologic responses to change within this environment. Combined, these results

    Glaser, Jochen

    2014-01-01

    Recent changes to the funding and governance of higher education and scientific research systems are affecting both the organisation of the sciences and the nature of universities as strategic actors in many countries. Transforming the organisational contexts in which research is carried out has altered the dynamics of scientific change through shifts in the authority relations that influence the development and implementation of organisational strategies. The first part of this book deals with the transformation of universities as strategic organisational actors - in some cases creating them as such - while the second shows how governance and authority shifts are affecting the kinds of research goals being pursued by academics in different public science systems. By bringing together the analysis of organisational change in universities with that of how institutional changes are affecting intellectual innovation in different fields, this volume integrates work in the sociology of organisations, science polic...

    2010-12-01

    Full Text Available Climate change will increasingly challenge ecosystem managers' ability to protect species diversity and maintain ecosystem function. In response, the National Park Service and the United States Forest Service have promoted climate change adaptation as a management strategy to increase ecosystem resilience to changing climatic conditions. However, very few examples of completed adaptation plans or projects exist. Here, we examine managers' perceptions of internal and external institutional barriers to implementing adaptation strategies. We conducted semi-structured interviews (n=32 with regional managers and agency staff in six park and forest units in Washington State. We found that internal barriers, including unclear mandates from superiors and bureaucratic rules and procedures, are perceived as greater constraints than external barriers related to existing federal environmental laws. Respondents perceived process-oriented environmental laws, such as the National Environmental Policy Act, as enablers of adaptation strategies, and prescriptive laws, such as the Endangered Species Act, as barriers. Our results suggest that climate change adaptation is more often discussed than pursued, and that institutional barriers within agencies limit what can be accomplished.

    Mobile laser scanning (MLS) has become a popular technique for road inventory, building modelling, infrastructure management, mobility assessment, etc. Meanwhile, due to the high mobility of MLS systems, it is easy to revisit interested areas. However, change detection using MLS data of street environment has seldom been studied. In this paper, an approach that combines occupancy grids and a distance-based method for change detection from MLS point clouds is proposed. Unlike conventional occupancy grids, our occupancy-based method models space based on scanning rays and local point distributions in 3D without voxelization. A local cylindrical reference frame is presented for the interpolation of occupancy between rays according to the scanning geometry. The Dempster-Shafer theory (DST) is utilized for both intra-data evidence fusion and inter-data consistency assessment. Occupancy of reference point cloud is fused at the location of target points and then the consistency is evaluated directly on the points. A point-to-triangle (PTT) distance-based method is combined to improve the occupancy-based method. Because it is robust to penetrable objects, e.g. vegetation, which cause self-conflicts when modelling occupancy. The combined method tackles irregular point density and occlusion problems, also eliminates false detections on penetrable objects.

    Mycotoxins are toxic metabolites produced by fungal species that commonly contaminate staple foods and feeds. They represent an unavoidable problem due to their presence in globally consumed cereals such as rice, maize and wheat. Most mycotoxins are immunosuppressive agents and some are carcinogens, hepatotoxins, nephrotoxins, and neurotoxins. Worldwide trends envision a stricter control of mycotoxins, however, the changing global environment may not be the ideal setting to control and reduce the exposure to these toxins. Although new technologies allow us to inspect the multi-mycotoxin presence in foods, new sources of exposure, gaps in knowledge of mycotoxins interactions, appearance of "emergent" mycotoxins and elucidation of consequent health effects can complicate their control even more. While humans are adapting to cope with environmental changes, such as food scarcity, decreased food quality, mycotoxin regulations, crop production and seasonality, and other climate related modifications, fungal species are also adapting and increased cases of mycotoxin adverse health effects are likely to occur in the future. To guarantee access to quality food for all, we need a way to balance global mycotoxin standards with the realistic feasibility of reaching them, considering limitations of producers and designing strategies to reduce mycotoxin exposure based on sound research.

  1. Bridging political economy analysis and critical institutionalism: an approach to help analyse institutional change for rural water services

    2015-03-01

    Full Text Available This paper argues that approaches to understanding local institutionsfor natural resource management based on “critical institutionalism” (Cleaver2012, which emphasises the importance of improvisation and adaptationacross different scales, can be placed within broader political economy analysisframeworks for assessing challenges in public services delivery from national tolocal levels. The paper uses such an extended political economy analysis approachto understand the role of the international NGO WaterAid and its partners in Mali inrelation to institutions for financing rural water services, drawing on collaborativeresearch undertaken in 2010 and 2011. The case study shows that WaterAid’sapproach can be understood through elements of both mainstream and criticalinstitutionalist thinking. At local government level, WaterAid primarily promotesformal institutional arrangements, which exhibit the challenge of “reforms assignals” (Andrews 2013, where institutional reforms appear to happen but lackthe intended function. However, the work of WaterAid’s partners at communitylevel supports processes of “institutional bricolage” through which they try togradually work with local actors to find ways of ‘best fit’ for financing rural waterservices which adapt existing local practices into new arrangements.

  2. Dynamics and life histories of northern ungulates in changing environments

    Regional climate and local weather conditions can profoundly influence life history parameters (growth, survival, fecundity) and population dynamics in northern ungulates (Post and Stenseth 1999, Coulson et al. 2001). The influence is both direct, for example through reduced growth or survival (Aanes et al. 2000, Tyler et al. 2008), and indirect, for example through changes in resource distribution, phenology and quality, changes which subsequently influence consumer dynamics (Post et al. 2008). By comparing and contrasting data from three spatially independent populations of ungulates, I discuss how variation in local weather parameters and vegetation growth influence spatial and temporal dynamics through changes in life history parameters and/or behavioural dynamics. The data originate from long term (11-15 years) monitoring data from three populations of ungulates in one subarctic and two high Arctic sites; semi-domesticated reindeer (Rangifer tarandus tarandus) in northern Norway, Svalbard reindeer (R. t. platyrhynchus) on Spitsbergen and muskoxen (Ovibos moschatus) in Northeast Greenland. The results show that juvenile animals can be particularly vulnerable to changes in their environment, and that this is mirrored to different degrees in the spatio-temporal dynamics of the three populations. Adverse weather conditions, acting either directly or mediated through access to and quality of vegetation, experienced by young early in life, or even by their dams during pregnancy, can lead to reduced growth, lower survival and reduced reproductive performance later in life. The influence of current climatic variation, and the predictions of how local weather conditions may change over time, differs between the three sites, resulting in potentially different responses in the three populations.

  4. Assessing institutional capacities to adapt to climate change - integrating psychological dimensions in the Adaptive Capacity Wheel

    2013-03-01

    Several case studies show that "soft social factors" (e.g. institutions, perceptions, social capital) strongly affect social capacities to adapt to climate change. Many soft social factors can probably be changed faster than "hard social factors" (e.g. economic and technological development) and are therefore particularly important for building social capacities. However, there are almost no methodologies for the systematic assessment of soft social factors. Gupta et al. (2010) have developed the Adaptive Capacity Wheel (ACW) for assessing the adaptive capacity of institutions. The ACW differentiates 22 criteria to assess six dimensions: variety, learning capacity, room for autonomous change, leadership, availability of resources, fair governance. To include important psychological factors we extended the ACW by two dimensions: "adaptation motivation" refers to actors' motivation to realise, support and/or promote adaptation to climate. "Adaptation belief" refers to actors' perceptions of realisability and effectiveness of adaptation measures. We applied the extended ACW to assess adaptive capacities of four sectors - water management, flood/coastal protection, civil protection and regional planning - in North Western Germany. The assessments of adaptation motivation and belief provided a clear added value. The results also revealed some methodological problems in applying the ACW (e.g. overlap of dimensions), for which we propose methodological solutions.

  5. Complementing institutional with localised strategies for climate change adaptation: a South-North comparison.

    Climate change and disasters pose a serious risk to sustainable development. In the South, local coping strategies are an important element of adaptation to climate and disaster risk. Such strategies have emerged because of the limited assistance provided by urban actors and associated social security and governance systems. In the North, in contrast, local coping strategies are comparatively poorly developed. However, the extent of the changing climatic conditions is also reducing the capacity of Northern institutions to deal with climatic extremes and variability, which emphasises the need for more local-level engagement in the North. This paper analyses the differences in local and institutional responses to climate change and disasters in a Southern and a Northern city (San Salvador, El Salvador, and Manchester, United Kingdom, respectively), and highlights how the lessons learned might be translated into an improved distributed governance system; that is, an 'integrated engagement model', where local and institutionalised responses support rather than hinder each other, as is currently the case.

  6. Does Integrated Water Resources Management Support Institutional Change? The Case of Water Policy Reform in Israel

    Directory of Open Access Journals (Sweden)

    2010-03-01

    Full Text Available Many international efforts have been made to encourage integrated water resources management through recommendations from both the academic and the aid and development sectors. Recently, it has been argued that integrated water resources management can help foster better adaptation of management and policy responses to emerging water crises. Nevertheless, few empirical studies have assessed how this type of management works in practice and what an integrated water management system implies for institutional adaptation and change. Our assessment of the Israeli water sector provides one view of how they can be shaped by an integrated structure in the water sector. Our analysis of recent efforts to adapt Israel's water management system to new conditions and uncertainties reveals that the interconnectedness of the system and the consensus decision-making process, led by a dominant actor who coordinates and sets the policy agenda, tends to increase the complexity of negotiations. In addition, the physical integration of water management leads to sunk costs of large-scale physical infrastructure. Both these factors create a path dependency that empowers players who receive benefits from maintaining the existing system. This impedes institutional reform of the water management system and suggests that integrated water resources management creates policy and management continuity that may only be amenable to incremental changes. In contrast, real adaptation that requires reversibility and the ability to change management strategies in response to new information or monitoring of specific management outcomes.

  7. The paradoxical effects of institutional change for the legitimacy of European governance: the case of EU Social Policy

    Directory of Open Access Journals (Sweden)

    Frank Wendler

    2004-07-01

    Full Text Available .This article discusses the tensions between two aspects of institutional change in the EU: the adaptation of institutional arrangements with the prospect of the legitimization of Community governance within a policy-making arena on the one hand, and the external evaluation of these institutional developments from the viewpoint of democratic theory on the other. Taking up the example of EU Social Policy, the argument proposed is twofold: First, a reconstruction of the institutional evolution in this field shows that strong tendencies towards the adaptation of Community governance to its contested legitimacy base – with regard to power relations, the behaviour of actors, the definition of policy ideas and the mechanisms of institutional change itself – are present. Second, evaluating these changes from the perspective of democratic theory reveals legitimacy deficits that are not just related to the imbalance of the input- and output-dimensions of legitimacy, but also to the tension between different normative standards of legitimate governance.

    Full Text Available This review paper highlights the organizational aspect of the learning process and addresses decision making from the theoretical coordinates of complexity, as a perspective that may provide a new comprehension of problems and their solution mechanisms. Daily practice reveals that behavioral dynamics in an organization are not always a response to optimal decision-making strategies. Higher learning institutions make clear the need of realigning the decision making to the contextual conditions of both the organization and its members. That is a fertile ground for the evaluation of other epistemological stances.

  10. Evolution of migration in a periodically changing environment.

    Science.gov (United States)

    Blanquart, F; Gandon, S

    2011-02-01

    The ability to migrate can evolve in response to various forces. In particular, when selection is heterogeneous in space but constant in time, local adaptation induces a fitness cost on immigrants and selects against migration. The evolutionary outcome, however, is less clear when selection also varies temporally. Here, we present a two-locus model analyzing the effects of spatial and temporal variability in selection on the evolution of migration. The first locus is under temporally varying selection (various periodic functions are considered, but a general nonparametric framework is used), and the second locus is a modifier controlling migration ability. First, we study the dynamics of local adaptation and derive the migration rate that maximizes local adaptation as a function of the speed and geometry of the fluctuations in the environment. Second, we derive an analytical expression for the evolutionarily stable migration rate. When there is no cost of migration, we show that higher migration rates are favored when selection changes fast. When migration is costly, however, the evolutionarily stable migration rate is maximal for an intermediate speed of the variation of selection. This model may help in understanding the evolution of migration in a broad range of scenarios and, in particular, in host-parasite systems, where selection is thought to vary quickly in both space and time.

    Williams, Laura; Colesie, Claudia; Büdel, Burkhard

    2015-04-01

    The Soil Crust INternational (SCIN) project aims to achieve improved appreciation of the importance and functioning of Biological Soil Crusts (BSC) in Europe. Four sites throughout Europe were identified for having important, yet diverse BSC communities: Gössenheim in Germany, Almeria in Spain, Öland in Sweden and Hochtor in Austria. These sites vary greatly in geographic and environmental conditions; and constitute, along with cyanobacteria, algae, bryophytes and fungi a host of green algal and cyanobacterial lichen species. Many of the lichen species occur in two-four locations, despite the climatic differences, and it has been observed that species are morphologically distinctive between sites. Lichens may be adapted to different environmental conditions by symbiosis with photobionts that are suited to the local conditions. Therefore, we may expect to find that a lichen species that can survive in diverse habitats to be less photobiont specific than species with a narrow range. In recent years it has been discovered that lichens can switch their photobiont throughout the course of their lives. Whether lichens can associate with an available photobiont and switch when a preferred photobiont becomes available is not conclusively known, or whether as habitats are affected by climate change, lichens will be able to switch to a new photobiont to survive changing conditions. A transplantation experiment of lichens between biomes was installed in each of the SCIN sites to investigate the potential of different lichen species to assimilate to a new environment. Where the same lichen species occurred in 2 or more locations samples were transplanted from their natural location to the foreign for a period of 2 years. Controls were also applied; this consisted of samples being transplanted within their own site to assess the effect of the transplantation itself. The photobionts of key species are sequenced to analyse diversity of photobiont interactions within/between the

    1996-01-01

    A distinguishing feature of American health care is its emphasis on advanced technology. Yet today's changing health care environment is overhauling the engine of technological innovation. The rate and direction of technological innovation are affected by a complex of supply- and demandside factors, including biomedical research, education, patent law, regulation, health care payment, tort law, and more. Some distinguishing features of technological innovation in health care are now at increased risk. Regulatory requirements and rising payment hurdles are especially challenging to small technology companies. Closer management of health care delivery and payment, particularly the standardization that may derive from practice guidelines and clamping down on payment for investigational technologies, curtails opportunities for innovation. Levels and distribution of biomedical research funding in government and industry are changing. Financial constraints are limiting the traditional roles of academic health centers in fostering innovation. Despite notable steps in recent years to lower regulatory barriers and speed approvals, especially for products for life-threatening conditions, the Food and Drug Administration is under great pressure from Congress, industry, and patients to do more. Technology gatekeeping is shifting from hundreds of thousands of physicians acting on behalf of their patients to fewer, yet more powerful, managed care organizations and health care networks. Beyond its direct effects on adoption, payment, and use of technologies, the extraordinary buying leverage of these large providers is cutting technology profit margins and heightening competition among technology companies. It is contributing to unprecedented restructuring of the pharmaceutical and medical device industries, leading to unprecedented alliances with generic product companies, health care providers, utilization review companies, and other agents. These industry changes are already

    Directory of Open Access Journals (Sweden)

    2009-09-01

    Full Text Available How can institutions contribute to the building of civil society in the twenty- first century? It is clear that the old laissez-faire approach and the more recent neo-conservative reliance on the market have failed to deliver housing for many people. On the other hand the state-based welfare housing model espoused by the Australian Labor Party over the twentieth century has also been beset by problems. Social alienation, and the crisis in affordable housing make the case that individualist approaches to urban living are not working. More communal solutions are needed - solutions attuned to a complex view of civil society outlined by Michael Edwards' tripartite definition. At the same time the onset of global warming now prompts Australians to create more environmentally sustainable ways of living. Addressing the theme of responsibility, this paper focuses on citizenship in its broader environmental, social and active forms. It analyses interviews and documentary evidence concerning the planning and development of Christie Walk, an innovative, medium density eco-city development in Adelaide. The investigation reveals the effects of some Australian institutions on residents' efforts to live socially and environmentally sustainable lives in an urban environment. The paper offers transdisciplinary research and analysis, linking the fields of history, urban housing, community development and environmental theory.

    2012-01-01

    In view of the massive quantities of space debris already deposited in outer space, any effort aimed at guaranteeing the sustainability of mankind's access to outer space and the continued safety of space operations must not be limited exclusively to mitigating the creation of new debris, but must also focus on the active removal of existing pieces of debris from space (remediation) as a matter of necessity. Presently, technologies that will enable active debris removal (ADR) are only just emerging. As the technology develops, however, several legal, regulatory and institutional issues that may hinder the conduct of ADR activities must also be addressed. This paper highlights and explores some of the foregoing issues in an effort to draw international attention to these matters and ultimately to pave the way for the smooth conduct of ADR activities once the technology matures.

    The goal of NICCR (National Institute for Climatic Change Research) was to mobilize university researchers, from all regions of the country, in support of the climatic change research objectives of DOE/BER. The NICCR Midwestern Regional Center (MRC) supported work in the following states: North Dakota, South Dakota, Nebraska, Kansas, Oklahoma, Minnesota, Iowa, Missouri, Wisconsin, Illinois, Michigan, Indiana, and Ohio. The MRC of NICCR was able to support nearly $8 million in climatic change research, including $6,671,303 for twenty projects solicited and selected by the MRC over five requests for proposals (RFPs) and $1,051,666 for the final year of ten projects from the discontinued DOE NIGEC (National Institute for Global Environmental Change) program. The projects selected and funded by the MRC resulted in 135 peer-reviewed publications and supported the training of 25 PhD students and 23 Masters students. Another 36 publications were generated by the final year of continuing NIGEC projects supported by the MRC. The projects funded by the MRC used a variety of approaches to answer questions relevant to the DOE’s climate change research program. These included experiments that manipulated temperature, moisture and other global change factors; studies that sought to understand how the distribution of species and ecosystems might change under future climates; studies that used measurements and modeling to examine current ecosystem fluxes of energy and mass and those that would exist under future conditions; and studies that synthesized existing data sets to improve our understanding of the effects of climatic change on terrestrial ecosystems. In all of these efforts, the MRC specifically sought to identify and quantify responses of terrestrial ecosystems that were not well understood or not well modeled by current efforts. The MRC also sought to better understand and model important feedbacks between terrestrial ecosystems, atmospheric chemistry, and regional

  1. The political economy of institutional change in the electricity supply industry

    Rufin, Carlos Ramon

    2000-09-01

    In the first part, a positive political economy model of the behavior of public enterprise, consumer electoral preferences, electoral platform choices of political parties, and side payments by production factors ("suppliers") to political parties, is used to analyze the political economy of choices among three alternative institutional arrangements: competition among private firms, private monopoly, or public enterprise monopoly. The analysis shows that political choices will be biased in favor of public enterprise, because consumers and suppliers benefit from its behavior. Voter and politician ideologies can temper or exacerbate this logic. Competition for economic rents increases the likelihood of public enterprise. Lastly, a weak judiciary can also make public enterprise likelier, but it creates uncertainty about parties' future actions and therefore it lowers the effectiveness of supplier side payments. In Part 2, the model's conclusions are tested for the electricity supply industry (ESI) across a cross-section of more than 80 countries. Coding is used to compute scores for observed outcomes with regard to reliance on competition versus monopoly and on private versus public ownership. Multiple indicators for the hypothesized explanatory variables are aggregated using factor analysis. OLS regressions show that ideology plays an important role in both competition and property outcomes, and to a lesser extent, distributional conflict, while judicial independence does not in general have a clear effect. In the last part, the validity of the same hypotheses is tested by means of a comparison of the process of restructuring of the ESI in Argentina, Bolivia, Brazil, and Chile. The case studies show that ideology plays a major role in shaping the outcomes of the institutional change process; distributional conflict, or the conflict over the economic rents that can be extracted from the electricity industry, also has a significant influence on institutional change

    Limited by the condition of information, technology and natural elements, the compulsive institutions in the environment governance can not form a "hard constraint" to the individuals. Because of the individual's speculative behaviors, the government's deviation from its environmental governance, and the non-cooperative game between individuals and the legal organization, the implementation of the compulsive institutions is not as good as being expected. Through analyzing the mechanism of the compulsive institutions, this paper puts forward some suggestions to enhance the efficiency of such institutions' implementation.

In particular, the entire project is designed to evaluate the influence of global climate change and land-use practices on biodiversity and ecological flows associated with ecotones, and will assess the feasibility of monitoring ecotones as early indicators of global change. The later stages of the project will recommend landscape management strategies for ecotones that produce desirable patterns of biodiversity and ecological flows. The result of the project--a comprehensive body of information on the theory and management of biodiversity and ecological flows associated with ecotones--will be part of the planning for research to be carried out under the International Geosphere-Biosphere Program.

Objectives: To conduct a comparative analysis of the expectations of older people from urban, rural, and institutional environments concerning nursing care with respect to the care provided and elements of a comprehensive geriatric assessment. Material and methods: The study comprised 2,627 individuals above the age of 65 years living in urban (n=935 and rural (n=812 areas as well as nursing homes (n=880. Results: Family care was most often expected both in urban (56.6% and rural (54.7% environments, followed by care provided simultaneously by a family and nurse (urban – 18.8%; rural – 26.1% and realized only by a nurse (urban – 24.6%; rural – 19.2%. Not surprisingly, nursing home residents most commonly expected nursing care (57.5% but 33.1% preferred care provided by family or friends and neighbors. In the whole cohort of people living in the home environment (n=1,718, those living with family demonstrated willingness to use primarily care implemented by the family (62.0%, while respondents living alone more often expected nursing services (30.3%. In the logistic regression model, among the respondents living in the city, only the form of care already received determined the expectations for nursing care. Among the respondents living in the county, the presence of musculoskeletal disorders, better nutritional status, and current care provided by family decreased expectations for nursing care.

    Full Text Available Considering its very low fertility and high age at childbearing, Italy stands alone in the European context and can hardly be compared with other countries, even those in the Southern region. The fertility decline occurred without any radical change in family formation. Individuals still choose (religious marriage for leaving their parental home and rates of marital dissolution and subsequent step-family formation are low. Marriage is being postponed and fewer people marry. The behaviours of young people are particularly alarming. There is a delay in all life cycle stages: end of education, entry into the labour market, exit from the parental family, entry into union, and managing an independent household. Changes in family formation and childbearing are constrained and slowed down by a substantial delay (or even failure with which the institutional and cultural framework has adapted to changes in economic and social conditions, in particular to the growth of the service sector, the increase in female employment and the female level of education. In a Catholic country that has been led for almost half a century by a political party with a Catholic ideology, the paucity of attention to childhood and youth seems incomprehensible. Social policies focus on marriage-based families already formed and on the phases of life related to pregnancy, delivery, and the first months of a newborn's life, while forming a family and childbearing choices are considered private affairs and neglected.

    2009-01-01

    This article analyzes the particularities of the decentralization of the state's action which took place in the Federative Republic of Brazil in the 1990 s. It presents the circumstances surrounding the political-institutional government environment which constructed the scenario in the implementation of decentralized management in the healthcare sector. It identifies challenges in rebuilding federative relations arising from the field of macroeconomic management, the social policies management and the attempts to rearrange the public sector and public administration in institutional and management terms. The aim is to reflect on the situation of federal, state and municipal governments when implementing decentralizing processes. The conclusion is that decentralization in the country was operated in the midst of the strengthening of the nation as well as of convergence and tension between two distinct projects to reform the state: a liberalizing transnational economic project of state modernization, and a national project, socially built, to expand and universalize rights and to redemocratize the state. The federative innovations, in addition pressures and influences of those two projects, determined the intergovernmental relations in reorganizing the management of public policies.

    Full Text Available Background: The transformation of a surgical trainee into a surgeon is strongly influenced by the quality of teaching in the operating theater. This study investigates the perceptions of residents about the educational environment of the operating theater and identifies variables that may improve the operating theater education of our trainees. Materials and Methods: Residents in the department of surgery anonymously evaluated teaching in the operating room using the operating theater education environment measure. The residents evaluated 33 variables that might have an impact on their surgical skills within the operating theater. The variables were grouped into four subscales; teaching and training, learning opportunities, operating theater atmosphere and workload/supervision/support. Differences between male and female residents and junior and senior registrars were assessed using Mann-Whitney test. Statistical analysis was completed with the statistics package for the social sciences version 17. Results: A total of 33 residents were participated in this study. Twenty nine (88% males and 4 (12% females. 30 (90% were junior registrars. The mean total score was 67.5%. Operating theater atmosphere subscale had the highest score of 79.2% while workload/supervision/support subscale had the least score of 48.3%. There were significant differences between male and female resident′s perception of workload/supervision/support P 0.05. Conclusion: This study has shown a satisfactory teaching environment based on the existing local realities of means, resources and tools and highlighted the need for improvement in workload/supervision/support in our institution. An acceptable learning environment in the operating theatre will produce surgeons that are technically competent to bridge the gap in the enormous unmet need for surgical care in Nigeria.

    Kahrl, Fredrich James

    support further improvements in efficiency and scale up renewable generation at an acceptable level of cost and reliability. Chapter 6 examines energy use and GHG emissions from nitrogen fertilizer use, arguing that energy use and GHG emissions from nitrogen fertilizer use in China are high relative to other countries because of China's historical support for small and medium-sized enterprises using domestic technology; its continued provision of energy subsidies to fertilizer producers; and its lack of a well-functioning agricultural extension system. The case studies illustrate the limits of energy and climate policy in China without institutional reform. China's leaders have historically relied on economic growth to defer the difficult changes in political economy that accompany economic and social transition. However, many of the challenges of energy and climate policy require political decisions that reallocate resources among stakeholders. For instance, restructuring the Chinese economy away from heavy industrial investment and toward a higher GDP share of consumption will require financial sector reforms, such as interest rate liberalization or higher dividend payments for state-owned enterprises, that reallocate income from the industrial sector to households. Increasing power system flexibility will require price reforms that reallocate revenues and costs among generators, between generators and the grid companies, between producers and ratepayers, among ratepayer classes, and between and among provinces. Strong public interest institutions are needed to make these changes, which suggests that China's energy and GHG emissions trajectories will be determined, to a large extent, by the politics of institutional reform.

    For more than 40 years the Texas Institute of Behavioral Research (IBR) has given special attention to assessment and evaluation of drug user populations, addiction treatment services and various cognitive and behavioral interventions. Emphasis has been on studies in real-world settings and the use of multivariate methodologies to address evaluation issues within the context of longitudinal natural designs. Historically, its program of addiction treatment research may be divided into three sequential epochs-the first era dealt mainly with client assessment and its role in treatment outcome and evaluation (1969-89), the second focused upon modeling the treatment process and the importance of conceptual frameworks (1989-2009) in explaining the relationships among treatment environment, client attributes, treatment process and outcome, and the third (and current) era has expanded into studying tactical deployment of innovations and implementation. Recent projects focus upon adapting and implementing innovations for improving early engagement in adolescent residential treatment settings and drug-dependent criminal justice populations. Related issues include the spread of human immunodeficiency virus/acquired immune deficiency syndrome and other infectious diseases, organizational and systems functioning, treatment costs and process related to implementation of evidence-based practices.

  4. Institutional change for strong sustainable consumption: sustainable consumption and the degrowth economy

    Directory of Open Access Journals (Sweden)

    Joachim H. Spangenberg

    2014-07-01

    Full Text Available The environmental space concept illustrates that socially unsustainable underconsumption must be overcome and environmentally unsustainable overconsumption must be phased out. The planetary boundaries help to quantify the “ceiling,” while the social protection floor concept operationalizes the linea de dignidad, the minimal conditions for a dignified life. In order for Western societies to respect these limits, significant institutional change is needed with respect to both orientations and mechanisms. For the ceiling, this article suggests a shift to an orientation of “better but less” for affluent groups, and toward “enough and better” for those still living in poverty. The corresponding mechanisms include a redistribution of income and wealth, a cap on income, an unconditional minimum income, and a strengthening of democracy. The choice of instruments has to take into account that consumption is to a large degree not an individual but a social act and to employ informational, financial, and legal measures that overcome the preference of decision makers for market instruments. Implementing these changes would alter the fabric of our societies. Important first steps can be taken here and now.

    Full Text Available It is an established fact that there exist leadership crisis at levels of organizational management. And organizational leadership crisis have occupied the front pages of various tabloids all over the world. Leadership crisis has engulfed various SMEs, conglomerates, governments, and financial institutions all over the world. The resultant effects of these have given rise to the present crisis, chaos and rots that are being witnessed in all nooks and crannies of the globe. This paper addressed issues relating leadership and the changing paradigm in the Nigerian financial landscape. The aim among others was to analyze the leadership theories especially the most appropriate circumstances for their application to current banking systems. The characteristics of and expectations from a good leaders; due mainly to the changing paradigm in banking e.g., optimizing the use of funds and building up management information system for decision making and better management of assets and liabilities and how leaders can rise to the challenges of global crisis. The theoretical findings showed that leaders should be abreast of risk inherent in currency market and keep an eye on the ball of underlying credit risk. It concludes that leadership needs to address issues of technical mismanagement, cosmetic management, desperate mismanagement and fraud which pose threat to the health of a bank. For effective leadership, there is need for good combination of teamwork, right organization, power and appropriate style of leadership.

  6. Beyond Bureaucracy? Assessing Institutional Change in the Governance of Water in England

    Directory of Open Access Journals (Sweden)

    Nigel Watson

    2009-10-01

    Full Text Available Alternative governance approaches in which non-state actors play a substantial role in policy making and implementation are currently attracting attention. Government-centred water bureaucracies have to adapt to increased complexity. Relationships among state and non-state actors in the English water sector have markedly changed in the last few decades in connection with the privatisation of water services, reform of arrangements for flood management, and implementation of the European Union Water Framework Directive (WFD. The paper assesses whether such changes represent a shift 'beyond bureaucracy' and the beginning of a new era of multi-party 'water governance'. From an examination of institutional reform in river basin management and flood risk management, the paper concludes that the water bureaucracy has actually strengthened its control, despite using language emphasising partnerships and collaborative governance. Responsibility for policy implementation has been reallocated among a range of public, private and civic groups. This 'neo-bureaucratic' arrangement is problematic because the government-centred water bureaucracy has lost some of its accountability and legitimacy, while the newer collaborative arrangements have little real influence over the direction of water policy. Governance capacity needs to be enhanced by adopting a collaborative approach to development of water policy in addition to its implementation.

    Kitchener, Martin; Mertz, Elizabeth

    2010-01-01

    This paper combines resources from the organization studies and sociology literatures to advance understanding of institutional change processes in healthcare that emerge from the professionalization projects of occupations. Conceptually, we introduce a model that combines the ‘archetype’ approach to analyzing structural change with a framework for analyzing the agency of emergent professions. We then employ the model to frame a historical case analysis (1972-2009) of the highly contested process by which the occupation of dental hygiene in the US fought to introduce a new organizational form, the alternative practice hygiene (APH) archetype. This archetype challenges the traditional model (the Dentist's Office archetype) that is supported by the dominant dentistry profession. Our analysis contributes two main sets of empirical findings. First, we present a systematic comparison of the APH and Dentist's Office archetypes in terms of their belief systems, formal structures, agents, and policy implications (e.g., access to services). Second, we provide an account of the agency of dental hygienists' attempts to secure the APH model as part of their professionalization project. PMID:21075497

    1999-08-01

    This paper explores the science-policy interaction and the extent to which and how institutional arrangements may be used as instruments for enhancing the effectiveness of the dialog. The first part develops the theory. The point of departure of the analysis is the internal dynamics of science and politics in their pure forms and the nature of the dynamics that are generated when these two distinct systems of behaviour meet. On this basis, then, the question of which functions the institutional apparatus should be able to serve in order to enhance the effectiveness of science-policy dialogue is addressed. This approach is then applied to an empirical case study of the Intergovernmental Panel on Climate Change (IPCC) from its establishment in 1988 to the provision of the Second IPCC Assessment Report in 1995. 53 refs., 3 figs., 2 tabs.

    The Yearbook of International Cooperation on Environment and Development aims to demonstrate the status of collaboration, the main obstacles to effective international solutions, and how to overcome them. The Yearbook assesses the achievements and the shortcomings of international co-operation, and helps the reader to distinguish between rhetoric and reality. The combination of independent, high-quality analysis and updated reference material makes this Yearbook an indispensable guide for decision-makers in government, international organizations, NGOs, and industry, as well as an essential source book for academic institutions, students, and libraries serving the concerned public. Current Issues and Key Themes in this edition focus on: (1) how effective environmental mega-conferences are in global environmental governance; (2) how the climate change regime can achieve its objective by addressing the very real concerns about climate-change impacts on human beings as much as on healthy ecosystems; (3) how the South Pacific Regional Environment Programme has been an effective regional agent for environmental protection and how it should cope with the challenges ahead; (4) how the Environmental Protocol to the Antarctic Treaty has contributed to strengthening international cooperation within the Treaty, but nevertheless is hampered by the vagueness of some core requirements and by the unresolved issues of jurisdiction, control, and enforcement in the Antarctic; (5) how the Ramsar Convention on Wetlands-neither rigorous nor extensive in its obligations-has acted as a vehicle for the development of a reasonably detailed policy framework for wetland conservation; (6) how Friends of the Earth International-among the world's largest, most diverse, and most influential environmental NGOs-has such internal diversity, in addition to its geographic spread and lack of agreed political ideology, that it risks its external profile becoming blurred and its internal

    Charles Darwin posited that secondary sexual characteristics result from competition to attract mates. In male songbirds, specialized vocalizations represent secondary sexual characteristics of particular importance because females prefer songs at specific frequencies, amplitudes, and duration. For birds living in human-dominated landscapes, historic selection for song characteristics that convey fitness may compete with novel selective pressures from anthropogenic noise. Here we show that black-capped chickadees (Poecile atricapillus) use shorter, higher-frequency songs when traffic noise is high, and longer, lower-frequency songs when noise abates. We suggest that chickadees balance opposing selective pressures by use low-frequency songs to preserve vocal characteristics of dominance that repel competitors and attract females, and high frequency songs to increase song transmission when their environment is noisy. The remarkable vocal flexibility exhibited by chickadees may be one reason that they thrive in urban environments, and such flexibility may also support subsequent genetic adaptation to an increasingly urbanized world.

    Research conducted by the six NIGEC Regional Centers during recent years is reported. An overview of the NIGEC program from its beginnings provides a description and evaluation of the program's vision, strategy and major accomplishments. The program's purpose was to support academic research on environmental change in regions of the country that had historically received relatively little federal funding. The overall vision of NIGEC may be stated as the performance of academic research on the regional interactions between ecosystems and climate. NIGEC's research presents important evidence on the impacts of climate variability and change, and in some cases adaptability, for a broad range of both managed and unmanaged ecosystems, and has thereby documented significant regional issues on the environmental responses to climate change. NIGEC's research has demonstrated large regional differences in the atmospheric carbon exchange budgets of croplands and forests, that there are significant variations of this exchange on diurnal, synoptic, seasonal and interannual time scales due to atmospheric variability (including temperature, precipitation and cloudiness), and that management practices and past history have predominant effects in grasslands and croplands. It is the mid-latitude forests, however, that have received more attention in NIGEC than any other specific ecosystem, and NIGEC's initiation of and participation in the AmeriFlux program, network of carbon flux measurement sites in North American old-growth forests, is generally considered to be its most significant single accomplishment. By including appendices with complete listings of NIGEC publications, principal investigators and participating institutions, this report may also serve as a useful comprehensive documentation of NIGEC.

    The Center for Global Security Research and Global Security Principal Directorate at Lawrence Livermore National Laboratory convened a workshop in July 2016 to consider “The Future of Nonproliferation in a Changed and Changing Security Environment.” We took a broad view of nonproliferation, encompassing not just the treaty regime but also arms control, threat reduction, counter-­proliferation, and countering nuclear terrorism. We gathered a group of approximately 60 experts from the technical, academic, political, defense and think tank communities and asked them what—and how much—can reasonably be accomplished in each of these areas in the 5 to 10 years ahead. Discussion was on a not-­for-­attribution basis. This document provides a summary of key insights and lessons-­learned and is provided to help stimulate broader public discussion of these issues. It is a collection of ideas as informally discussed and debated among a group of experts. The ideas reported here are the personal views of individual experts and should not be attributed to Lawrence Livermore National Laboratory.

A description of the dynamics of the institutional modifications in Germany, Italy, France, Japan, United Kingdom, USA, Mexico and Venezuela is presented, from the first petroleum 'shock', conducted mostly for the adaptation of the respective internal markets, to the new conditions imposed by the international market. The authors use the political and institutional changes occurred in the aforementioned, for the identification of the disagreement among those changes and those implemented in the hydrocarbon Brazilian national market.

    1999-09-01

    In the 10 years since the Challenger accident, NASA has developed a set of stable and capable processes to prepare the Space Shuttle for safe launch and return. Capitalizing on the extensive experience gained from a string of over 50 successful flights, NASA today is changing the way it does business in an effort to reduce cost. A single Shuttle Flight Operations Contractor (SFOC) has been chosen to operate the Shuttle. The Government role will change from direct "oversight" to "insight" gained through understanding and measuring the contractor's processes. This paper describes the program management changes underway and the NASA Safety and Mission Assurance (S&MA) organization's philosophy, role, and methodology for pursuing this new approach. It describes how audit and surveillance will replace direct oversight and how meaningful performance metrics will be implemented.

  5. Revising the formal, retrieving the hidden: Undergraduate curricular reform in medicine and the scientific, institutional, & social transformation of the clinical training environment

    2009-12-01

    In 2004, members of the McGill University Faculty of Medicine began implementing a new curriculum for undergraduate medical education entitled, Physicianship: The Physician as Professional and Healer. The initiative underscores the idea that physician training entails cultivating not only scientific knowledge and technical skill, but a mindset guided by intrinsic principles of doctoring. Although the McGill case exemplifies a wide-spread paradigm shift in medical teaching, there is a dearth of analysis concerning the degree of congruency between the objectives of formal undergraduate curricular revision and the so-called 'hidden curriculum' of the hospital training environment. With Physicianship as a point of departure, this dissertation maps evolutionary patterns in clinical medicine and, using qualitative methods, analyzes the perspectives of twenty physician-educators on curricular reform and the transforming clinical training environment. Physicians interviewed were generally supportive of the new curricular initiative. Concerns were raised, however, that many recent changes within the teaching hospital environment interfere with students' cultivation of professional and healer attributes. These changes were organized into three main themes: scientific, institutional, and social. Physicians expressed concern that what is often considered beneficial for patients is often detrimental for medical training. For example, increased use of diagnostic technologies has improved patient care but reduces opportunities for trainees' clinical skill development. Concern was raised that the concept of selfless service has been undermined through recent shift-work regulations and a culture gap between older and younger generation physicians. Alternatively, some perceived new policies of the clinical environment to be more conducive to physicians' self-care and quality of life. Younger trainees were often described as more competent in managing medical information, more open

    Full Text Available Introduction: With the adoption of routine screening mammography, breast cancers are being diagnosed at earlier stages, with DCIS now accouting for 22.5% of all newly diagnosed breast cancers. This has been attributed to both increased breast cancer awareness and improvements in breast imaging techniques. How have these changes, including the increased use of image-guided sampling techniques, influenced the clinical practice of breast surgery?Methods: The institutional pathology database was queried for all breast surgeries, including breast reconstruction, performed in 1995 and 2005. Cosmetic procedures were excluded. The results were analysed utilizing the Chi-square test.Results: Surgical indications changed during 10-year study period, with an increase in preoperatively diagnosed cancers undergoing definitive surgical management. ADH, and to a lesser extent, ALH, became indications for surgical excision. Fewer surgical biopsies were performed for indeterminate abnormalities on breast imaging, due to the introduction of stereotactic large core biopsy. While the rate of benign breast biopsies remained constant, there was a higher percentage of precancerous and DCIS cases in 2005. The overall rate of mastectomy decreased from 36.8% in 1995 to 14.5% in 2005. With the increase in sentinel node procedures, the rate of ALND dropped from 18.3% to 13.7%. Accompanying the increased recognition of early-stage cancers, the rate of positive ALND also decreased, from 43.3% to 25.0%.Conclusions: While the rate of benign breast biopsies has remained constant over a recent 10-year period, fewer diagnostic surgical image-guided biopsies were performed in 2005. A greater percentage of patients with breast cancer or preinvasive disease have these diagnoses determined before surgery. More preinvasive and Stage 0 cancers are undergoing surgical management. Earlier stage invasive cancers are being detected, reflected by the lower incidence of axillary nodal

    2010-02-01

    Eukaryotic cells are often exposed to fluctuations in growth conditions as well as endogenous and exogenous stress-related agents. During development, global patterns of gene transcription change substantially, and these changes are associated with altered patterns of DNA replication and larger distances between replication origins in somatic cells compared to embryos. Conversely, when cells experience difficulties while replicating DNA, the replication program is dramatically altered and distances between replication origins decrease. Recent evidence indicates that each unit of replication, or replicon, can correspond to one or more potential replication origins, but in the case of multiple potential origins, only one is selected to initiate replication of the replicon. How one origin is selected from multiple potential origins and how origin densities are regulated during genome duplication remains unclear. The following review addresses some of the mechanisms involved in regulating replication origins during both a normal and perturbed eukaryotic cell cycle.

  12. HESS Opinions: Hydrologic predictions in a changing environment: behavioral modeling

    2011-02-01

    Full Text Available Most hydrological models are valid at most only in a few places and cannot be reasonably transferred to other places or to far distant time periods. Transfer in space is difficult because the models are conditioned on past observations at particular places to define parameter values and unobservable processes that are needed to fully characterize the structure and functioning of the landscape. Transfer in time has to deal with the likely temporal changes to both parameters and processes under future changed conditions. This remains an important obstacle to addressing some of the most urgent prediction questions in hydrology, such as prediction in ungauged basins and prediction under global change. In this paper, we propose a new approach to catchment hydrological modeling, based on universal principles that do not change in time and that remain valid across many places. The key to this framework, which we call behavioral modeling, is to assume that there are universal and time-invariant organizing principles that can be used to identify the most appropriate model structure (including parameter values and responses for a given ecosystem at a given moment in time. These organizing principles may be derived from fundamental physical or biological laws, or from empirical laws that have been demonstrated to be time-invariant and to hold at many places and scales. Much fundamental research remains to be undertaken to help discover these organizing principles on the basis of exploration of observed patterns of landscape structure and hydrological behavior and their interpretation as legacy effects of past co-evolution of climate, soils, topography, vegetation and humans. Our hope is that the new behavioral modeling framework will be a step forward towards a new vision for hydrology where models are capable of more confidently predicting the behavior of catchments beyond what has been observed or experienced before.

    Climate change is expected to be a top driver of global biodiversity loss in the 21st century. It poses new challenges to conserving and managing imperiled species, particularly in marine and estuarine ecosystems. The use of climate-related science in statutorily driven species management, such as under the U.S. Endangered Species Act (ESA), is in its early stages. This article provides an overview of ESA processes, with emphasis on the mandate to the National Marine Fisheries Service (NMFS) to manage listed marine, estuarine, and anadromous species. Although the ESA is specific to the United States, its requirements are broadly relevant to conservation planning. Under the ESA, species, subspecies, and "distinct population segments" may be listed as either endangered or threatened, and taking of most listed species (harassing, harming, pursuing, wounding, killing, or capturing) is prohibited unless specifically authorized via a case-by-case permit process. Government agencies, in addition to avoiding take, must ensure that actions they fund, authorize, or conduct are not likely to jeopardize a listed species' continued existence or adversely affect designated critical habitat. Decisions for which climate change is likely to be a key factor include: determining whether a species should be listed under the ESA, designating critical habitat areas, developing species recovery plans, and predicting whether effects of proposed human activities will be compatible with ESA-listed species' survival and recovery. Scientific analyses that underlie these critical conservation decisions include risk assessment, long-term recovery planning, defining environmental baselines, predicting distribution, and defining appropriate temporal and spatial scales. Although specific guidance is still evolving, it is clear that the unprecedented changes in global ecosystems brought about by climate change necessitate new information and approaches to conservation of imperiled species.

    It is currently unclear whether the amino acid substitutions that occur during protein evolution are primarily driven by adaptation, or reflect the random accumulation of neutral changes. When estimated from genomic data, the proportion of adaptive amino acid substitutions, called α, was found to vary greatly across species, from nearly zero in humans to above 0.5 in Drosophila. These variations have been interpreted as reflecting differences in effective population size, adaptation being supposedly more efficient in large populations. Here, we investigate the influence of effective population size and other biological parameters on the rate of adaptive evolution by simulating the evolution of a coding sequence under Fisher's geometric formalism. We explicitly model recurrent environmental changes and the subsequent adaptive walks, followed by periods of stasis during which purifying selection dominates. We show that, under a variety of conditions, the effective population size has only a moderate influence on α, and an even weaker influence on the per generation rate of selective sweeps, modifying the prevalent view in current literature. The rate of environmental change and, interestingly, the dimensionality of the phenotypic space (organismal complexity) affect the adaptive rate more deeply than does the effective population size. We discuss the reasons why verbal arguments have been misleading on that subject and revisit the empirical evidence. Our results question the relevance of the "α" parameter as an indicator of the efficiency of molecular adaptation.

    Higher education in geosciences has imminent goals to prepare students with modern geoscience knowledge and skills to meet the increased demand on trained professionals for working on the big challenges faced by geoscience disciplines, such as the global environmental change, world energy supplies, sustainable development, etc. In order to reach the goal, the geoscience education in post-secondary institutes worldwide has to attract and retain enough students and to train students with knowledge and skills needed by the society. The classroom innovations that can encourage and support student investigations and research activities are key motivation mechanisms that help to reach the goal. This presentation describes the use of GeoBrain, an innovative geospatial knowledge system, as a powerful educating tool for motivating and facilitating innovative undergraduate and graduate teaching and research in geosciences. Developed in a NASA funded project, the GeoBrain system has adopted and implemented the latest Web services and knowledge management technologies for providing innovative methods in publishing, accessing, visualizing, and analyzing geospatial data and in building/sharing geoscience knowledge. It provides a data-rich online learning and research environment enabled by wealthy data and information available at NASA Earth Observing System (EOS) Data and Information System (EOSDIS). Students, faculty members, and researchers from institutes worldwide can easily access, analyze, and model with the huge amount of NASA EOS data just like they possess such vast resources locally at their desktops. The online environment provided by GeoBrain has brought significant positive changes to geosciences education in higher-education institutes because of its new concepts and technologies, motivation mechanisms, free exploration resources, and advanced geo- processing capabilities. With the system, the used-to-be very challenging or even impossible teaching tasks has

    The major claim in Acemoglu, Aghion, Bursztyn and Hemous (2012) (AABH) is that subsidies for research and development of clean technologies are more important than carbon taxes when dealing with climate change. However, they – unconventionally – assume that a patent only lasts for one period. In this note we introduce long-lived patents into the AABH model. This makes the role of a research subsidy for clean technologies in AABH far less crucial and reestablishes the role of the carbon tax. This is good news as it is far easier to tax emissions than to pick the right technologies to subsidize.(Author)

    Our thesis relates to the trans-national corporations whose activities are blamed in the climate change problem. It deals with their actions in relation to the political process engaged by the states at the beginning of the 1990's, and with their influence on the definition of the solutions to be brought to the problem. More precisely, as part of a broader reflection on the social-historical institution of the problem - the fact that it is instituted, by means of the imaginary, in and by particular societies, at a certain moment of their history and for a certain time - and considering the period extending from 1989 to 2001, we wanted to elucidate two things. On the one hand, why, for (or against) what and how did these corporations act (i.e. the cause, the aim and the content of their actions) in relation to the political process. And, on the other hand, up to what point these actions (making the most of a 'relational power'), but also the sole fact that the studied corporations exist (a situation from which they derive an 'institutional power'), had effects on the process and, more especially, on the definition of the solutions. The choice of analysing these major 'non-st= ate' actors arose from two intermingled motivations. The main motivation was to demonstrate the need to take into account these large firms (in addition to the states, the interstate institutions and the other non-state actors) to be able to understand the evolution of the political process, and thus to remedy at the lack of studies on the subject. The other motivation was to contribute, more in filigree, at the comprehension of the way capitalism - understood as a 'social regime' (i.e. a specific type of institution of the society) that can exist only in and by the corporation - face this problem which, more than any other ecological problem, deeply questions it, that means threatens it.

    The rainfed rice-growing environment is perhaps one of the most vulnerable to water stress such as drought and floods. It is important to determine the spatial extent of the stress-prone areas to effectively and efficiently promote proper technologies (e.g., stress-tolerant varieties) to tackle the problem of sustainable food production. This study was conducted in Odisha state located in eastern India. Odisha is predominantly a rainfed rice ecosystem (71% rainfed and 29% canal irrigated during kharif-monsoon season), where rice is the major crop and staple food of the people. However, rice productivity in Odisha is one of the lowest in India and a significant decline (9%) in rice cultivated area was observed in 2002 (a drought year). The present study analyzed the temporal rice cropping pattern in various ecosystems and identified the stress-prone areas due to submergence (flooding) and water shortage. The spatial distribution of rice areas was mapped using MODIS (MOD09Q1) 250-m 8-day time-series data (2000-2010) and spectral matching techniques. The mapped rice areas were strongly correlated (R(2) = 90%) with district-level statistics. Also the class accuracy based on field-plot data was 84.8%. The area under the rainfed rice ecosystem continues to dominate, recording the largest share among rice classes across all the years. The use of remote-sensing techniques is rapid, cost-effective, and reliable to monitor changes in rice cultivated area over long periods of time and estimate the reduction in area cultivated due to abiotic stress such as water stress and submergence. Agricultural research institutes and line departments in the government can use these techniques for better planning, regular monitoring of land-use changes, and dissemination of appropriate technologies.

    In the past, the required introductory veterinary nutrition course at Michigan State University's College of Veterinary Medicine (MSU-CVM) has provided 29 hours of didactic lectures, with student performance evaluated by short-answer or multiple-choice questions. Because of a 50% reduction in allotted course credits and a change in prerequisites for admission, the course is being redesigned to focus on three of 29 nutrition competencies outlined by the American College of Veterinary Nutrition. Professional communication skills will be developed through small-group learning experiences, case-based problems, and videotaped interviews with standardized clients to teach and assess nutrition competencies. Assessment strategies will differ from traditional multiple-choice examinations and include pre- and post-course self-efficacy ratings, written evaluations from trained standardized clients, and oral and written evaluations from coaches or facilitators.

In fact, the PLC is not only alive and working worldwide in thousands of applications, but it is also integrating well with related technologies. Long-term survival is a larger question - probably unanswerable given the pace of technological change. However, a few questions arise about the PLC today and in the immediate future: (1) What`s happening with programming languages? (2) Will there continue to be a {open_quotes}blurring of the lines{close_quotes} between the PLC and other technologies, and what role will software play in this integration? (3) How will the PLC`s cost and size affect the market?

  8. Ages of celiac disease: from changing environment to improved diagnostics.

    2011-08-28

    From the time of Gee's landmark writings, the recent history of celiac disease (CD) can be divided into many ages, each driven by a diagnostic advance and a deeper knowledge of disease pathogenesis. At the same time, these advances were paralleled by the identification of new clinical patterns associated with CD and by a continuous redefinition of the prevalence of the disease in population. In the beginning, CD was considered a chronic indigestion, even if the causative food was not known; later, the disease was proven to depend on an intolerance to wheat gliadin, leading to typical mucosal changes in the gut and to a malabsorption syndrome. This knowledge led to curing the disease with a gluten-free diet. After the identification of antibodies to gluten (AGA) in the serum of patients and the identification of gluten-specific lymphocytes in the mucosa, CD was described as an immune disorder, resembling a chronic "gluten infection". The use of serological testing for AGA allowed identification of the higher prevalence of this disorder, revealing atypical patterns of presentation. More recently, the characterization of autoantibodies to endomysium and to transglutaminase shifted the attention to a complex autoimmune pathogenesis and to the increased risk of developing autoimmune disorders in untreated CD. New diagnostic assays, based on molecular technologies, will introduce new changes, with the promise of better defining the spectrum of gluten reactivity and the real burden of gluten related-disorders in the population. Herein, we describe the different periods of CD experience, and further developments for the next celiac age will be proposed.

  9. Adaptive wetland management in an uncertain and changing arid environment

    Full Text Available Wetlands in the arid western United States provide rare and critical migratory bird habitat and constitute a critical nexus within larger social-ecological systems (SES where multiple changing land-use and water-use patterns meet. The Bear River Migratory Bird Refuge in Utah, USA, presents a case study of the ways that wetland managers have created adaptive management strategies that are responsive to the social and hydrological conditions of the agriculture-dominated SES within which they are located. Managers have acquired water rights and constructed infrastructure while cultivating collaborative relationships with other water users to increase the adaptive capacity of the region and decrease conflict. Historically, water management involved diversion and impoundment of water within wetland units timed around patterns of agricultural water needs. In the last 20 years, managers have learned from flood and drought events and developed a long-term adaptive management plan that specifies alternative management actions managers can choose each year based on habitat needs and projected water supply. Each alternative includes habitat goals and target wetland water depth. However, wetland management adapted to agricultural return-flow availability may prove insufficient as population growth and climate change alter patterns of land and water use. Future management will likely depend more on negotiation, collaboration, and learning from social developments within the SES than strictly focusing on water management within refuge boundaries. To face this problem, managers have worked to be included in negotiations with regional water users, a strategy that may prove instructive for other wetland managers in agriculture-dominated watersheds.

    The authors reframe a curriculum change from a traditional lecture-based to an integrated patient-centered approach as an intervention for changing the culture and hidden curriculum of an institution in ways that promote professionalism. Within this context, the authors articulate some of the inherent process and relational factors brought about by these curricular changes that are essential elements of this intervention process. In 1998 the University of North Dakota School of Medicine and Health Sciences (UNDSMHS) introduced a new preclinical patient-centered learning (PCL) curriculum for first- and second-year medical students. Case-based, small-group learning forms the critical foundation of the PCL process, and an integrated basic and clinical science didactic component supports this process. At the student level, the case-based PCL process generates innovative opportunities for professionalism education from the explicitly articulated formal content that arises naturally from the cases, but more importantly from the implicit values inherent to the PCL small-group process itself--humanism, accountability, pursuit of excellence, and altruism. Further, the organizational changes necessary for the transformation to the PCL curriculum required process changes at student, faculty, and administrative levels that have resulted in a cultural shift toward relationship centeredness within the institution. The authors describe the evolution and structure of the PCL curriculum at UNDSMHS and how this curricular transformation has served as an intervention that promotes professionalism and institutional culture change through (1) processes at the student level that present new opportunities for professionalism education, and (2) processes at student, faculty, administrative, and institutional levels that have created an institutional culture that supports, models, and promotes relationship-centered professional values.

    Based on the system theory, this paper examines the impacts of institutions on vocational education in three approaches, viz, the societal foundations for education system, the role of vocational education within the education system, and the division of labor and the job market. Education itself functioning as a social institution, has a strong influence on individuals, t education are divided into different categories according to the diversified and professionalized nature of occupations. Vocational education is not valued originates from the dual track stratifying teenager students into vocational education and academic/general education, leading to inequality and inequity within the education system. The defect of vocational schooling lies in the fact that it fails to create a real working environment employment relationship as the reality in the workplace, which makes an effective skills-learning dependent on educational resources in a real world of work where the availability of such resources relies on a more flexible employment of labour force.%本文以系统论为理论基础,主要从教育的社会性、学校教育制度以及社会劳动分工和用工制度等角度分析了各种制度因素对职业教育的影响。文章认为,教育体系本身就是一种社会制度,它能够在个人身上产生不可抗拒的影响力;教育类型的分化是以社会职业的多样化和专业化为前提;将教育类型狭隘地二分为普通教育与职业教育是导致职业教育受鄙薄的观念性根源,以这种观念上的偏见为支撑的教育分流制度造成了教育系统内部的不平等;学校职业教育不可弥补的缺陷在于,它无法模拟或复制真实的工作氛围与工作关系,因此有效的职业学习必须依赖于现实工作世界的教育性资源,然而工作场所职业学习资源的可得性则得益于趋向扁平化的用工制度。

  13. Strategic Institutional Change to Support Advancement of Women Scientists in the Academy: Lessons from a Study of ADVANCE-IT Projects

    While women's representation among undergraduate and graduate degree-earners has grown steadily in most science fields, progress at the faculty level has been slow to realize, especially in upper academic ranks and in higher status institutions. This is only partly explained by the slow turnover of faculty positions. While some efforts to address this issue have aimed to support individual women and foster their career success, the National Science Foundation's ADVANCE program has taken a different approach, calling for institutions to take a systemic and organizational approach to enhance women's representation in the academy. Since 2001, some 50 institutions have received ADVANCE Institutional Transformation (IT) awards to develop such systemic approaches. Most ADVANCE-IT projects have attended to structures (e.g. committee and departmental leadership roles), processes (e.g. hiring), policy (e.g. family leave), attitudes and awareness (e.g. training for chairs), and workplace climate, as well as interventions that focus on faculty members as valuable human resources. Our research team is studying ADVANCE institutions' approaches to organizational change, by identifying and categorizing individual change interventions, examining how they combine to build an overall change portfolio, and considering how change interventions are selected or adapted to fit a specific institutional context. Because universities are complex organizations composed of multiple, loosely coupled, interconnected sub-systems, an overall change strategy cannot depend on a single type of intervention. Yet any particular intervention might be deployed on behalf of multiple goals and in a variety of forms that may depend on the context, or institutional system, in which it is introduced. We will discuss some common types of strategic intervention used in ADVANCE-IT projects, categorized by Bolman and Deal's (1991) four main perspectives or "lenses" for understanding organizational issues.

    A key limitation on the use of two-wavelength DIAL or its multi-spectral generalization is the unknown spectral structure of the topographically backscattered lidar signals in the absence of the target materials. Although some of the factors responsible for the background spectral structure can be measured in advance, others, such as the terrain differences are highly variable and usually unknown. For applications to tactical reconnainssance and high-altitude surveillance where the background is continuously changing, the inability to account for the background can seriously degrade sensor performance. This study describes a method for estimating both the spectral dependence of the background as well as the path-integrated concentration, or CL, from the same data set using dual Kalman filtering. The idea is to run parallel filters that estimate the background and CL using input from the other filter. The approach is illustrated on a variety of synthetic data sets and signal injections into background data collected by the U.S. Army WILDCAT sensor at Dugway Proving Ground.

    2016-01-01

    As we welcome Romania as our 22nd Member State in late July, now is a good time to reflect on the geographical enlargement process that was initiated in 2010.   Let me begin by setting the context. CERN operates in an increasingly complex and globalised world. Political and economic developments in the European neighbourhood and well beyond can have an impact on our work – directly or indirectly, in the short term or in a much longer perspective. We need to anticipate that change as far as we can, while also being agile enough to meet the challenges that we do not expect. The UK’s EU referendum on 23 June is a case in point. Because CERN is an organisation founded to facilitate cooperation across borders, Brexit is an uncomfortable truth to many of us. It is, nevertheless, the outcome of the political processes of one of our founding Member States, and is something we must respect. Whatever direction the UK now takes, we will be working with the country’s particle ph...

  16. Ages of celiac disease: From changing environment to improved diagnostics

    2011-01-01

    From the time of Gee's landmark writings, the recent history of celiac disease (CD) can be divided into manyages, each driven by a diagnostic advance and a deeperknowledge of disease pathogenesis. At the same time,these advances were paralleled by the identification of new clinical patterns associated with CD and by a continuous redefinition of the prevalence of the diseasein population. In the beginning, CD was considered a chronic indigestion, even if the causative food was notknown; later, the disease was proven to depend on anintolerance to wheat gliadin, leading to typical mucosalchanges in the gut and to a malabsorption syndrome. This knowledge led to curing the disease with a gluten-free diet. After the identification of antibodies to gluten(AGA) in the serum of patients and the identification of gluten-specific lymphocytes in the mucosa, CD was described as an immune disorder, resembling a chronic "gluten infection". The use of serological testing for AGA allowed identification of the higher prevalence of this disorder, revealing atypical patterns of presenta-tion. More recently, the characterization of autoantibod-ies to endomysium and to transglutaminase shifted the attention to a complex autoimmune pathogenesis and to the increased risk of developing autoimmune disor-ders in untreated CD. New diagnostic assays, based on molecular technologies, will introduce new changes, with the promise of better defining the spectrum of gluten reactivity and the real burden of gluten related-disorders in the population. Herein, we describe the different periods of CD experience, and further devel-opments for the next celiac age will be proposed.

  20. Adaptation, plasticity, and extinction in a changing environment: towards a predictive theory.

    Directory of Open Access Journals (Sweden)

    Luis-Miguel Chevin

    Full Text Available Many species are experiencing sustained environmental change mainly due to human activities. The unusual rate and extent of anthropogenic alterations of the environment may exceed the capacity of developmental, genetic, and demographic mechanisms that populations have evolved to deal with environmental change. To begin to understand the limits to population persistence, we present a simple evolutionary model for the critical rate of environmental change beyond which a population must decline and go extinct. We use this model to highlight the major determinants of extinction risk in a changing environment, and identify research needs for improved predictions based on projected changes in environmental variables. Two key parameters relating the environment to population biology have not yet received sufficient attention. Phenotypic plasticity, the direct influence of environment on the development of individual phenotypes, is increasingly considered an important component of phenotypic change in the wild and should be incorporated in models of population persistence. Environmental sensitivity of selection, the change in the optimum phenotype with the environment, still crucially needs empirical assessment. We use environmental tolerance curves and other examples of ecological and evolutionary responses to climate change to illustrate how these mechanistic approaches can be developed for predictive purposes.

    This article assesses the role of local institutions in managing irrigation water use. Fifty irrigation systems in each country were studied in Nepal and Thailand to compare the influence of local institutions on performance of irrigation systems amid changes in external policy and market pressures. Nepal's new irrigation policy after the re-instatement of multiparty democracy in 1990 emphasized participatory irrigation management transferring the management responsibility from state authorities to water users. The water user associations of traditional farmer-managed irrigation systems were formally recognized by requiring registration with related state authorities. In Thailand also government policies encouraged people's participation in irrigation management. Today water users are directly involved in management of even some large irrigation systems at the level of tertiary canals. Traditional communal irrigation systems in northern Thailand received support for system infrastructure improvement but have faced increased interference from government. In Thailand market development supported diversification in farming practices resulting in increased areas under high water-demanding commercial crops in the dry season. In contrast, the command areas of most irrigation systems in Nepal include cereal-based subsistence farming with only one-third having commercial farming. Cropping intensities are higher in Nepal than in Thailand reflecting, in part, differences in availability of land and management. In both countries local institutions play an important role in maintaining the performance of irrigation systems as external drivers and local contexts change. Local institutions have provided alternative options for irrigation water use by mediating external pressures.

    Global climate change is expected to pose increasing challenges for cities in the following decades, placing greater stress and impacts on multiple social and biophysical systems, including population health, coastal development, urban infrastructure, energy demand, and water supplies. Simultaneously, a strong global trend towards urbanisation of poverty exists, with increased challenges for urban populations and local governance to protect and sustain the wellbeing of growing cities. In the context of these 2 overarching trends, interdisciplinary research at the city scale is prioritised for understanding the social impacts of climate change and variability and for the evaluation of strategies in the built environment that might serve as adaptive responses to climate change. This article discusses 2 recent initiatives of The Earth Institute at Columbia University (EI) as examples of research that integrates the methods and objectives of several disciplines, including environmental health science and urban planning, to understand the potential public health impacts of global climate change and mitigative measures for the more localised effects of the urban heat island in the New York City metropolitan region. These efforts embody 2 distinct research approaches. The New York Climate & Health Project created a new integrated modeling system to assess the public health impacts of climate and land use change in the metropolitan region. The Cool City Project aims for more applied policy-oriented research that incorporates the local knowledge of community residents to understand the costs and benefits of interventions in the built environment that might serve to mitigate the harmful impacts of climate change and variability, and protect urban populations from health stressors associated with summertime heat. Both types of research are potentially useful for understanding the impacts of environmental change at the urban scale, the policies needed to address these

    Full Text Available Abstract Background The complicity of the South African health sector in apartheid and the international relevance of human rights as a professional obligation prompted moves to include human rights competencies in the curricula of health professionals in South Africa. A Train-the-Trainers course in Health and Human Rights was established in 1998 to equip faculty members from health sciences institutions nationwide with the necessary skills, attitudes and knowledge to teach human rights to their students. This study followed up participants to determine the extent of curriculum implementation, support needed as well as barriers encountered in integrating human rights into health sciences teaching and learning. Methods A survey including both quantitative and qualitative components was distributed in 2007 to past course participants from 1998-2006 via telephone, fax and electronic communication. Results Out of 162 past participants, 46 (28% completed the survey, the majority of whom were still employed in academic settings (67%. Twenty-two respondents (48% implemented a total of 33 formal human rights courses into the curricula at their institutions. Respondents were nine times more likely (relative risk 9.26; 95% CI 5.14-16.66 to implement human rights education after completing the training. Seventy-two extracurricular activities were offered by 21 respondents, many of whom had successfully implemented formal curricula. Enabling factors for implementation included: prior teaching experience in human rights, general institutional support and the presence of allies - most commonly coworkers as well as deans. Frequently cited barriers to implementation included: budget restrictions, time constraints and perceived apathy of colleagues or students. Overall, respondents noted personal enrichment and optimism in teaching human rights. Conclusion This Train-the-Trainer course provides the historical context, educational tools, and collective motivation

    Unmanned Aerial Systems (UAS) are widely used for different earth-sciences applications providing chiefly a link between in-situ ground based measurements and satellite remote sensing observations. The "Autonomous Flying Platforms for Atmospheric and Earth Surface Observations" project (APAESO) of the Energy, Environment and Water Research Center (EEWRC) at the Cyprus Institute is aimed at the dual purpose of carrying out atmospheric and earth-surface observations in the (Eastern) Mediterranean (APAESO is being supported by a grant of the Cyprus Research Promotion Foundation: ΝΕΑ ΥΠΟΔΟΜΗ/ΝΕΚΥΠ/0308/09). After having acquired four CRUISERS (ET-Air, Slovakia) as UAS platforms and a substantial range of scientific instruments to be employed on these platforms, we are currently in the process of specifying and implementing a more permanent, operational UAS Facility at the EEWRC of CyI. This facility will consist of three main components: (i) Ground/Operation component (GOC); (ii) Instrumentation/Mission component (IMC) and (iii) Flight team component (FTC). The GOC will be comprised by the following elements: a) a dedicated Control and Operation Facility, which will be employed mainly during flight operations and scientific missions, b) workshops and technical infrastructure and c) appropriate storage space for platforms, platform elements, scientific instrumentations, spare parts and maintenance and miscellaneous materials. The already mentioned range of different scientific instruments for atmospheric measurements and remote sensing investigations and a number of "mandatory" instruments, which will be flown on every mission (e.g., basic meteorological sensors, a simple video camera, GPS, etc.) as well as a calibration and gauging laboratory forms the core of the IMC. The FTC consists mainly of a number of skilled and experienced pilots with a basic understanding of scientific UAS applications. The implementation of appropriate pre-, in- and post

  18. Obesity and the built environment: changes in environmental cues cause energy imbalances.

    Science.gov (United States)

    Cohen, D A

    2008-12-01

    The past 30 years have seen dramatic changes in the food and physical activity environments, both of which contribute to the changes in human behavior that could explain obesity. This paper reviews documented changes in the food environment, changes in the physical activity environment and the mechanisms through which people respond to these environments, often without conscious awareness or control. The most important environmental changes have been increases in food accessibility, food salience and decreases in the cost of food. The increases in food marketing and advertising create food cues that artificially stimulate people to feel hungry. The existence of a metabolic pathway that allows excess energy to be stored as fat suggests that people were designed to overeat. Many internal mechanisms favor neurophysiologic responses to food cues that result in overconsumption. External cues, such as food abundance, food variety and food novelty, cause people to override internal signals of satiety. Other factors, such as conditioning and priming, tie food to other desirable outcomes, and thus increase the frequency that hunger is stimulated by environmental cues. People's natural response to the environmental cues are colored by framing, and judgments are flawed and biased depending on how information is presented. People lack insight into how the food environment affects them, and subsequently are unable to change the factors that are responsible for excessive energy consumption. Understanding the causal pathway for overconsumption will be necessary to interrupt the mechanisms that lead to obesity.

  1. Defining "faculty" in academic medicine: responding to the challenges of a changing environment.

    Science.gov (United States)

    Block, Steven M; Sonnino, Roberta E; Bellini, Lisa

    2015-03-01

    Academic medicine in the United States is at a crossroads. There are many drivers behind this, including health care reform, decreased federal research funding, a refined understanding of adult learning, and the emergence of disruptive innovations in medicine, science, and education. As faculty members are at the core of all academic activities, the definition of "faculty" in academic medicine must align with the expectations of institutions engaged in patient care, research, and education. Faculty members' activities have changed and continue to evolve. Academic health centers must therefore define new rules of engagement that reflect the interplay of institutional priorities with the need to attract, retain, and reward faculty members. In this Commentary, the authors describe and explore the potential effects of the changing landscape for institutions and their clinical faculty members. The authors make a case for institutions to adapt faculty appointment, evaluation, and promotion processes, and they propose a framework for a standardized definition of "faculty" that allows for individual variability. This framework also provides a means to evaluate and reward faculty members' contributions in education, research, and clinical care. The authors propose a deliberate national conversation to ensure that careers in academic medicine remain attractive and sustainable and that the future of academic medicine is secure.

  2. [Comment on "Meeting Ph.D. Graduates' needs in a changing global environment"] Challenges to fostering interdisciplinary graduate education

    C. Susan Weiler's article ("Meeting Ph.D. graduates' needs in a changing global environment," Eos, 55(13), 149, 151) calling for more care and attention to interdisciplinary graduate education illuminated an important and neglected issue. Weiler makes the excellent point that for society to manage complex natural systems effectively, it is imperative that we establish stronger connections between science and public policy. However, as a nation, the United States lacks the institutional research culture to foster this. Nor are we training sufficient numbers of professionals with the skills to make these connections; and when the small number of truly interdisciplinary scientists emerge annually into the workforce, there are few positions that fit them.I echo Weiler's call for increased interdisciplinary collaboration, and the necessary training to support this increase. However, there are some fundamental obstacles her article does not explore.

    Research on adaptation barriers is increasing as the need for climate change adaptation becomes evident. However, empirical studies regarding the emergence, causes and sustenance of adaptation barriers remain limited. This research identifies key contextual causes of adaptation barriers in water institutions in the mountainous Himalayan state of Himachal Pradesh in northern India. Semi-structured interviews were carried out with representatives from twenty-six key governmental, non-governmental, academic and research institutions in the State with responsibilities spanning domestic water supply, irrigation and hydropower generation, environmental monitoring and research. It identified low knowledge capacity and resources, policy implementation gaps, normative attitudes, and unavailability and inaccessibility of data and information compounded with weak interinstitutional networks as key adaptation barriers. Although these barriers are similar to those reported elsewhere, they have important locally-contextual root causes. For instance, inadequate resources result from fragmented resources allocation due to competing developmental priorities and the desire of the political leadership to please diverse electors, rather than climate scepticism. The identified individual barriers are found to be highly inter-dependent and closely intertwined which enables the identification of leverage points for interventions to maximise barrier removal. For instance, breaking down key barriers hindering accessibility to data and information, which are shaped by systemic bureaucracies and cultural attitudes, will involve attitudinal change through sensitisation to the importance of accurate and accessible data and information and the building trust between different actors, in addition to institutional structural changes through legislation and inter-institutional agreements. Approaching barriers as a system of contextually interconnected cultural, systemic, geographical and political

    Full Text Available Abstract Background The Healthy Options for Nutrition Environments in Schools (Healthy ONES study was an evidence-based public health (EBPH randomized group trial that adapted the Institute for Healthcare Improvement’s (IHI rapid improvement process model to implement school nutrition policy and environmental change. Methods A low-income school district volunteered for participation in the study. All schools in the district agreed to participate (elementary = 6, middle school = 2 and were randomly assigned within school type to intervention (n = 4 and control (n =4 conditions following a baseline environmental audit year. Intervention goals were to 1 eliminate unhealthy foods and beverages on campus, 2 develop nutrition services as the main source on campus for healthful eating (HE, and 3 promote school staff modeling of HE. Schools were followed across a baseline year and two intervention years. Longitudinal assessment of height and weight was conducted with second, third, and sixth grade children. Behavioral observation of the nutrition environment was used to index the amount of outside foods and beverages on campuses. Observations were made monthly in each targeted school environment and findings were presented as items per child per week. Results From an eligible 827 second, third, and sixth grade students, baseline height and weight were collected for 444 second and third grade and 135 sixth grade students (51% reach. Data were available for 73% of these enrolled students at the end of three years. Intervention school outside food and beverage items per child per week decreased over time and control school outside food and beverage items increased over time. The effects were especially pronounced for unhealthy foods and beverage items. Changes in rates of obesity for intervention school (28% baseline, 27% year 1, 30% year 2 were similar to those seen for control school (22% baseline, 22% year 1, 25% year 2 children

    Full Text Available The purpose of the article discusses reunification of children from institutional care to their birth families within the context of actual transformation of child protection system. Reunification is the process of reintegration of vulnerable child placed „out of home“to his or her family, if it is the best interest of the child. Reunification of children placed in institutions should be a primary goal of the system because of a preference for the role of parents in the law, especially in the Convention on the Rights of the Child. The article is based on the analysis of documents of international organizations dealing with the protection of children's rights, international studies and program policy documents. The topic of reunification can be viewed from different perspectives, such as law and its influence on social policy and the practices of social work, the part of deinstitutionalization process or the decision making process. The main question is about interest of parents to care for their child. Social workers have to know characteristic of the family and the child. Then the reunification can start effectively. The family, child, specialists from institutions and social workers should participate on the process in more detail. In the conclusion of the paper the author tries to show principles and central values on which the successful process of reunification should be focused. She highlightes holistic view and complex assessment of family and safe family environment, the principle of partnership with family, the working with individual plan for child, the support of new family services, the performing sufficient preparation of the child, the family and the social environment before reuenification, intensive social services for family after returning home and finally the need for research on the process of reunification from the perspective of the child, parents and the professionals

  13. Sensitizing events as trigger for discursive renewal and institutional change in Flanders’ environmental health approach, 1970s-1990s

    Science.gov (United States)

    2013-01-01

    Background Sensitizing events may trigger and stimulate discursive renewal. From a discursive institutional perspective, changing discourses are the driving force behind the institutional dynamics of policy domains. Theoretically informed by discursive institutionalism, this article assesses the impact of a series of four sensitizing events that triggered serious environmental health concerns in Flanders between the 1970s till the 1990s, and led onto the gradual institutionalization of a Flemish environmental health arrangement. Methods The Policy Arrangement Approach is used as the analytical framework to structure the empirical results of the historical analysis based on document analysis and in-depth interviews. Results Until the 1990s, environmental health was characterized as an ad hoc policy field in Flanders, where agenda setting was based on sensitizing events – also referred to as incident-driven. Each of these events contributed to a gradual rethinking of the epistemological discourses about environmental health risks and uncertainties. These new discourses were the driving forces behind institutional dynamics as they gradually resulted in an increased need for: 1) long-term, policy-oriented, interdisciplinary environmental health research; 2) policy coordination and integration between the environmental and public health policy fields; and 3) new forms of science-policy interactions based on mutual learning. These changes are desirable in order to detect environmental health problems as fast as possible, to react immediately and communicate appropriately. Conclusions The series of four events that triggered serious environmental health concerns in Flanders provided the opportunity to rethink and re-organize the current affairs concerning environmental health and gradually resulted into the institutionalization of a Flemish environmental health arrangement.

    Animals routinely adapt to changes in the environment in order to survive. Though reinforcement learning may play a role in such adaptation, it is not clear that it is the only mechanism involved, as it is not well suited to producing rapid, relatively immediate changes in strategies in response to environmental changes. This research proposes that counterfactual reasoning might be an additional mechanism that facilitates change detection. An experiment is conducted in which a task state changes over time and the participants had to detect the changes in order to perform well and gain monetary rewards. A cognitive model is constructed that incorporates reinforcement learning with counterfactual reasoning to help quickly adjust the utility of task strategies in response to changes. The results show that the model can accurately explain human data and that counterfactual reasoning is key to reproducing the various effects observed in this change detection paradigm.

  15. Dousing our inflammatory environment(s): is personal carbon trading an option for reducing obesity--and climate change?

    Science.gov (United States)

    Egger, G

    2008-09-01

    Obesity and climate change are two problems currently challenging humanity. Although apparently unrelated, an epidemiological approach to both shows a similar environmental aetiology, based in modern human lifestyles and their driving economic forces. One way of analysing this is through inflammation (defined as '. . . a disturbance of function following insult or injury') of both the internal (biological) and external (ecological) environments. Chronic, low-grade, systemic inflammation has recently been shown to accompany obesity, as well as a range of biological pathologies associated with obesity (diabetes, heart disease, some cancers, etc.). This is influenced by the body's inability to soak up excess glucose as a result of insulin resistance. In a broader sense, inflammation is a metaphor for ecological 'pathologies', manifest particularly in unnatural disturbances like climate change, ocean acidity, rising temperatures and species extinction, associated with the inability of the world's environmental 'sinks' to soak up carbon dioxide ('carbon resistance'?). The use of such a metaphorical analysis opens the possibilities for dealing with two interdisciplinary problems simultaneously. Strategies for managing climate change, including personal carbon trading, could provide a 'stealth intervention' for reducing population levels of obesity by increasing personal energy expenditure and decreasing energy-dense food intake, as well as reducing the carbon emissions causing climate change.

    2011-07-01

    Full Text Available Abstract Background Biologists studying adaptation under sexual selection have spent considerable effort assessing the relative importance of two groups of models, which hinge on the idea that females gain indirect benefits via mate discrimination. These are the good genes and genetic compatibility models. Quantitative genetic studies have advanced our understanding of these models by enabling assessment of whether the genetic architectures underlying focal phenotypes are congruent with either model. In this context, good genes models require underlying additive genetic variance, while compatibility models require non-additive variance. Currently, we know very little about how the expression of genotypes comprised of distinct parental haplotypes, or how levels and types of genetic variance underlying key phenotypes, change across environments. Such knowledge is important, however, because genotype-environment interactions can have major implications on the potential for evolutionary responses to selection. Results We used a full diallel breeding design to screen for complex genotype-environment interactions, and genetic architectures underlying key morphological traits, across two thermal environments (the lab standard 27°C, and the cooler 23°C in the Australian field cricket, Teleogryllus oceanicus. In males, complex three-way interactions between sire and dam parental haplotypes and the rearing environment accounted for up to 23 per cent of the scaled phenotypic variance in the traits we measured (body mass, pronotum width and testes mass, and each trait harboured significant additive genetic variance in the standard temperature (27°C only. In females, these three-way interactions were less important, with interactions between the paternal haplotype and rearing environment accounting for about ten per cent of the phenotypic variance (in body mass, pronotum width and ovary mass. Of the female traits measured, only ovary mass for crickets

    2014-01-01

    In order to shuttle substrates across the lipid bilayer, membrane proteins undergo a series of conformation changes that are influenced by protein structure, ligands, and the lipid environment. To test the effect of lipid on conformation change of the ABC transporter MolBC, EPR studies were conducted in lipids and detergents of variable composition. In both a detergent and lipid environment, MolBC underwent the same general conformation changes as detected by site-directed EPR spectroscopy. However, differences in activity and the details of the EPR analysis indicate conformational rigidity that is dependent on the lipid environment. From these observations, we conclude that native-like lipid mixtures provide the transporter with greater activity and conformational flexibility as well as technical advantages such as reconstitution efficiency and protein stability.

    Full Text Available Kenora is a small city located in northwestern Ontario, Canada. The study presented here focuses on Tunnel Island, 300 acres of forested land adjacent to Kenora’s downtown. The island is used and valued by both city residents and members of three nearby Ojibway nations. As a multiple-use, common-pool resource accessed by different groups for a range of non-extractive activities, the site has become an experiment in multicultural commons governance, and presents an excellent opportunity to examine the origins and development of institutions for managing collective environmental resources in an urban setting. Using participant observation, internet- and field-based user surveys, and semi-structured interviews, our research finds that grassroots ‘governance’ of the site is emerging through subtle processes of individual and social construction, with the strategies and norms (codes of conduct employed by users providing relative harmony on the trails, which suggests functioning commons institutions. Nevertheless, values-based and epistemic tensions exist among users, pointing to governance challenges for planned joint management of the site, and specifically the need to develop formal, legitimate, and yet flexible and inclusive arrangements that can operate in conjunction with the social practice of existing users.

    Expression variation plays an important role in plant adaptation, but little is known about the factors impacting the expression variation when population adapts to changing environment. We used RNA-seq data from 80 individuals in 14 Miscanthus lutarioriparius populations, which were transplanted into a harsh environment from native habitat, to investigate the expression level, expression diversity and genetic diversity for genes expressed in both environments. The expression level of genes with lower expression level or without SNP tended to be more changeable in new environment, which suggested highly expressed genes experienced stronger purifying selection than those at lower level. Low proportion of genes with population effect confirmed the weak population structure and frequent gene flow in these populations. Meanwhile, the number of genes with environment effect was the most frequent compared with that with population effect. Our results showed that environment and genetic diversity were the main factors determining gene expression variation in population. This study could facilitate understanding the mechanisms of global gene expression variation when plant population adapts to changing environment. PMID:27150248

  7. Total Environment of Change: Impacts of Climate Change and Social Transitions on Subsistence Fisheries in Northwest Alaska

    Directory of Open Access Journals (Sweden)

    Katie J. Moerlein

    2012-03-01

    Full Text Available Arctic ecosystems are undergoing rapid changes as a result of global climate change, with significant implications for the livelihoods of Arctic peoples. In this paper, based on ethnographic research conducted with the Iñupiaq communities of Noatak and Selawik in northwestern Alaska, we detail prominent environmental changes observed over the past twenty to thirty years and their impacts on subsistence-based lifestyles. However, we suggest that it is ultimately insufficient to try to understand how Arctic communities are experiencing and responding to climate change in isolation from other stressors. During interviews and participant observation documenting local observations of climatic and related environmental shifts and impacts to subsistence fishing practices, we find the inseparability of environmental, social, economic, cultural, and political realms for community residents. Many of our informants, who live in a mixed economy based on various forms of income and widespread subsistence harvesting of fish and game, perceive and experience climate change as embedded among numerous other factors affecting subsistence patterns and practices. Changing lifestyles, decreasing interest by younger generations in pursuing subsistence livelihoods, and economic challenges are greatly affecting contemporary subsistence patterns and practices in rural Alaska. Observations of climate change are perceived, experienced, and articulated to researchers through a broader lens of these linked lifestyle and cultural shifts. Therefore, we argue that to properly assess and understand the impacts of climate change on the subsistence practices in Arctic communities, we must also consider the total environment of change that is dramatically shaping the relationship between people, communities, and their surrounding environments.

  8. Molecular and cellular bases of adaptation to a changing environment in microorganisms.

    2016-10-26

    Environmental heterogeneity constitutes an evolutionary challenge for organisms. While evolutionary dynamics under variable conditions has been explored for decades, we still know relatively little about the cellular and molecular mechanisms involved. It is of paramount importance to examine these molecular bases because they may play an important role in shaping the course of evolution. In this review, we examine the diversity of adaptive mechanisms in the face of environmental changes. We exploit the recent literature on microbial systems because those have benefited the most from the recent emergence of genetic engineering and experimental evolution followed by genome sequencing. We identify four emerging trends: (i) an adaptive molecular change in a pathway often results in fitness trade-off in alternative environments but the effects are dependent on a mutation's genetic background; (ii) adaptive changes often modify transcriptional and signalling pathways; (iii) several adaptive changes may occur within the same molecular pathway but be associated with pleiotropy of different signs across environments; (iv) because of their large associated costs, macromolecular changes such as gene amplification and aneuploidy may be a rapid mechanism of adaptation in the short-term only. The course of adaptation in a variable environment, therefore, depends on the complexity of the environment but also on the molecular relationships among the genes involved and between the genes and the phenotypes under selection.

  9. Managing change in Higher Educational Institutions in South Africa: Some challenges

    L. Froneman

    2003-12-01

    Full Text Available Higher Education has a vital role in developing an internationally competitive economy, a more affluent society and a sturdy democracy. The newly released National Plan for Higher Education in South Africa should recognise the current social and economic status in the country to realign its mission, and to reconsider the location and target audience of the various institutions in the country, to optimally serve the educational needs of the communities. The proposals in the National Plan, however, attempts to attain in a few years what other stabilised countries took years. That poses major challenges to education management. The aim of this paper is to evaluate some aspects of the managerial skills in the national education authorities. By analysing the National Plan, and testing the views of a number of teaching staff, the conclusion is that there are serious doubts regarding the management acumen in the educational leadership and that various important aspects are left out in the Plan.

    2013-03-01

    Full Text Available The research has investigated the effect of corporate governance on strategic change in rural banks in the Eastern Region of Ghana. It was also examined the importance of governance mechanism and strategic decisions on weaknesses and threats to the banks effective operation. It has examined the understanding of ownership, board, and the top management team in strategic change on banks values. It has also revealed the relationship between strategic/policy changes and the bank performance in the community. A quantitative methodology was used for the study. The main instrument used for data collection was self-developed questionnaire. It was revealed that the importance of governance mechanism and strategic decisions on weaknesses and threats to the effective operation of the banks were 80% very important and 90% important. However, 70% of the management personnel strongly support formal policy development and implementation of the bank. The research concluded that corporate governance has an effect on strategic change on rural banking. It is recommended that strategic changes in rural banks can be implemented if the top management team and Board of Directors agreed and placed high importance on it. A good implementation of strategic change in rural banks will really improve their performance.

    The implementation of evidence-based treatments to deliver high-quality care is essential to meet the healthcare demands of aging populations. However, the sustainable application of recommended practice is difficult to achieve and variable outcomes well recognised. The NHS Institute for Innovation and Improvement Sustainability Model (SM) was designed to help healthcare teams recognise determinants of sustainability and take action to embed new practice in routine care. This article describes a formative evaluation of the application of the SM by the National Institute for Health Research Collaboration for Leadership in Applied Health Research and Care for Northwest London (CLAHRC NWL). Data from project teams' responses to the SM and formal reviews was used to assess acceptability of the SM and the extent to which it prompted teams to take action. Projects were classified as 'engaged,' 'partially engaged' and 'non-engaged.' Quarterly survey feedback data was used to explore reasons for variation in engagement. Score patterns were compared against formal review data and a 'diversity of opinion' measure was derived to assess response variance over time. Of the 19 teams, six were categorized as 'engaged,' six 'partially engaged,' and seven as 'non-engaged.' Twelve teams found the model acceptable to some extent. Diversity of opinion reduced over time. A minority of teams used the SM consistently to take action to promote sustainability but for the majority SM use was sporadic. Feedback from some team members indicates difficulty in understanding and applying the model and negative views regarding its usefulness. The SM is an important attempt to enable teams to systematically consider determinants of sustainability, provide timely data to assess progress, and prompt action to create conditions for sustained practice. Tools such as these need to be tested in healthcare settings to assess strengths and weaknesses and findings disseminated to aid development. This

    The major goal of this project was fostering, integrating, synthesizing, and disseminating experimental, observational, and modeling research on predicted climate change in the western region of the U.S. and the impacts of that change on the structure, productivity, and climatic interactions of the region's natural and managed ecological systems. This was accomplished through administering a competitive grants program developed in collaboration with the other four regional centers of the NICCR. The activities supported included efforts to synthesize research on climate change in the western U.S. through meta-analysis studies, model comparisons, and data synthesis workshops. Results from this work were disseminated to the scientific and public media. This project also supported the development of the NICCR web site, hosted at NAU, which was used as the means to accept pre-proposal and proposal submissions for each funding cycle, and served as a clearing house for public outreach for results from NICCR-funded research

    Full Text Available Stream flow plays a crucial role in the environment, society, and the economy, and identifying the causes of changes in runoff is important to understanding the impact of climate change and human activity. This study examines the variation trends in recorded runoff for the Xinshui River, a tributary of the Yellow River on the Loess Plateau, and uses hydrological simulations to investigate how climate change and human activity have contributed to those trends. Results show that the recorded runoff at the Daning station on the Xinshui River declined significantly from 1955–2008 with an abrupt change occurring in 1973. The Simplified Water Balance Model (SWBM simulates monthly discharge well with a Nash–Sutcliffe efficiency (NSE coefficient of 78% and a relative error of volumetric fit (RE of 0.32%. Runoff depth over the catchment in 1973–2008 fell by 25.5 mm relative to the previous period, with human activity and climate change contributing 60.6% and 39.4% of the total runoff reduction, respectively. However, the impacts induced by climate change and human activities are both tending to increase. Therefore, efforts to improve the ecology of the Loess Plateau should give sufficient attention to the impacts of climate change and human activity.

  5. August Hirt and "extraordinary opportunities for cadaver delivery" to anatomical institutes in National Socialism: a murderous change in paradigm.

    German anatomical institutes always had problems obtaining sufficient cadavers for research and training. In the National Socialist (NS) period this changed. Universities could count on "extraordinary opportunities for cadaver delivery." Most frequently tacitly, many bodies were those of victims of NS crimes. Scientists increasingly exploited the exceptional political situation to systematically supplement their institutional collections. Their endeavors to fill the, in their terms, "lamentable gaps" in their collections took on truly bizarre forms. In Austria, Jewish cemeteries were plundered for racial-political expansion of anatomical collections. A change in paradigm was merely the next step: intentional murder for the benefit of NS-oriented science. In December of 1942, anatomists meeting in Tübingen discussed plans for "material acquisition." August Hirt, director of the anatomical institute at the Reichsuniversität in Strasbourg, was to develop guidelines. There was express reference to "Auftrag Beger," which had already been conceived although not yet realized: at the behest of Hirt and the SS-scientific organization, "Ahnenerbe," the anthropologists Bruno Beger and Hans Fleischhacker selected 86 Jewish prisoners in Auschwitz in June of 1943 and deported them to the concentration camp at Struthof near Natzweiler, where they were murdered. The bodies were delivered to the anatomy department in Strasbourg for preparation and used as anatomical specimens. The Reichsuniversität Strasbourg was considered a center of excellence for Nazi ideology. For modern scientists, the elucidation of these criminal acts is not exhausted in the search for an answer to the questions of perpetrator, place, modus operandi or motive. A suitable memorial to the victims must go beyond mere quantification.

    2014-01-01

    Full Text Available Change is a factor of impact on managerial functions especially upon those related to the coordination and training of the human resources. Change management is a broad spectrum of means, referring to different types of change , however, it is generally used in the processing management and in the strategic management, in the information management , including the electronic one. The analysis of changes inside the organization is very important , these changes allow the organizations to be more adaptable and innovative. However, some changes may suddenly occur and will independently act of the managers’will. If we are talking about the human change, then we should mention that the importance of this dimension of the organizational change is essential. The way people relate to change can be affected by the position they occupy inside the organization and the attitudes they adopt facing the change influence the role that they assume with the greatest ease in the change processes. Leadership and the organizational culture are in a tight relationship. Manager evaluates its business, in addition to a number of work processes and products, and the cultural environment too, so conducive, in his view, that it should activate and record the organizational and work performance.

    Full Text Available Este artigo é uma discussão das relações entre instituições, interesses e idéias, tendo como referência empírica as experiências de concertação social na Europa e as reformas da previdência social na América Latina dos anos de 1990. Reconhecendo que o debate atual sobre essas reformas tem incorporado a importância da dimensão cognitiva dos processos políticos na tentativa de construir abordagens mais complexas e adequadas sobre os fenômenos em pauta, diferentemente das análises anteriores com essa preocupação, argumentamos que a ênfase dada ao papel das idéias até agora ainda não parece ser suficiente para explicar a natureza e a difusão dos processos de reformas econômicas e sociais, sua legitimidade ou sustentação política. É preciso que o processo de adoção das idéias produza resultados avaliados positivamente, oferecendo respostas, mesmo que não consensuais, para questões consideradas centrais na agenda pública. Além disso, há um complexo processo de aprendizado e de mimicking no âmbito das políticas sociais que permite elucidar alguns dos seus intrincados desdobramentos, fazendo com que estes elementos não possam ser desconsiderados, inclusive porque talvez permitam adicionar novas dimensões às abordagens das reformas econômicas e sociais inspiradas nas instituições ou na competição política.This article discusses the relations between institutions, interests and ideas, taking as its reference point experiences in social concertation in Europe and welfare system reforms in Latin America in the 1990s.

  14. Changing the Learning Environment in the College of Engineering and Applied Science Using Challenge Based Learning

    Directory of Open Access Journals (Sweden)

    Whitney Brooke Gaskins

    2015-02-01

    Full Text Available Over the past 20 years there have been many changes to the primary and secondary educational system that have impacted students, teachers, and post-secondary institutions across the United States of America. One of the most important is the large number of standardized tests students are required to take to show adequate performance in school. Students think differently because they are taught differently due to this focus on standardized testing, thus changing the skill sets students acquire in secondary school. This presents a critical problem for colleges and universities, as they now are using practices for and have expectations of these students that are unrealistic for the changing times. High dropout rates in the colleges of engineering have been attributed to the cultural atmosphere of the institution. Students have reported a low sense of belonging and low relatability to course material. To reduce negative experiences and increase motivation, Challenge Based Learning (CBL was introduced in an undergraduate Basic Electric Circuits (BEC course. CBL is a structured model for course content with a foundation in problem-based learning. CBL offers general concepts from which students derive the challenges they will address. Results show an improved classroom experience for students who were taught with CBL.

    在经济全球化的驱动下,一国的外部经济活动与内部制度环境显然已密不可分。为了探求制度环境与国际贸易竞争力的确切关系,笔者整理近三十年来国内外知名学者在该领域的理论研究和实证检验,沿着传统贸易理论、新贸易理论及新新贸易理论的线路梳理了国际贸易理论的发展,聚焦贸易便利化概念,提炼制度的确切定义,进而将制度与贸易的关系简化为竞争机制的贸易开放、制度保障的贸易安全与贸易便利性的关系,最后界定制度环境与贸易竞争力的关系。研究显示,制度安全是国际贸易稳定发展、经济稳步前进的充分条件。%Under the influence of economic globalization, one nation's external business activities cannot be isolated from its internal institutional environment. Early in the 70s of last century, scholars pointed out that there was a direct causational relevance between international trade and institution. In recent years this issue is becoming a highlight in academic circle. To probe into how the institutional environment affects global trade competitiveness, this article provides a review of studies in this area by domestic and overseas scholars in the past 30 years. In light of traditional, new, and new-new trade theories, our review entails a discussion of such problems as the theoretical development of international trade, trade convenience, precise definition of institutions, relation between trade security and trade convenience warranted by systems, and relationship between institutional environment and trade competitiveness.

  16. Conflicts, security and marginalisation: institutional change of the pastoral commons in a 'glocal' world.

    Haller, T; Van Dijk, H; Bollig, M; Greiner, C; Schareika, N; Gabbert, C

    2016-11-01

    This paper argues that pastoral commons are under increasing pressure not just from overuse by pastoralists themselves, but from land management policies. Since colonial times, these have been based on a persistent misconception of the nature of pastoral economies and combined with increasing land alienation and fragmentation through government policies and covert privatisation of pastures. The paper focuses especially on pastoral populations in African drylands and is based on long-term research by independent researchers summarising some of their experiences in western, eastern and southern Africa. Most of them are organised in the African Drylands Dialogue, trying to shed some light on the developments in these areas. Before discussing the actual situation of African pastoralists, the authors focus on basic institutional features of the political and economic management of common grazing lands. This is followed by an overview of land alienation processes in colonial times, which serves as a basis for understanding the current land alienation constellations. The paper then moves on to explain how and why pastoralists are framed by the national discourses as the 'other' and the 'troublemaker', even being labelled as terrorists in nation state contexts. This goes hand in hand with a new wave of land alienation in the form of large-scale land acquisitions or 'land grabbing' (including water grabbing and 'green grabbing' processes). The paper then outlines different coping and adaptation strategies adopted by pastoral groups in a context in which a range of different global and local political, economic and ecological situations interrelate ('glocal'). Finally, the paper discusses the way in which pastoralism could be reframed in a participatory way in the future.

  17. Transpiration of shrub species, Alnus firma under changing atmospheric environments in montane area, Japan

    In the large caldera of Mt. Aso in Japan, grasslands have been traditionally managed by the farmers. Due to changes in the social structure of the region, a large area of the grassland has been abandoned and was invaded by the shrubs with different hydrological and ecophysiological traits. Ecophysiological traits and their responses to seasonally changing environments are fundamental to project the transpiration rates under changing air and soil water environments, but less is understood. We measured the tree- and leaf-level ecophysiological traits of a shrub, Alnus firma in montane region where both rainfall and soil water content drastically changes seasonally. Sap flux reached the annual peak in evaporative summer (July-August) both in 2013 and 2014, although the duration was limited within a short period due to the prolonged rainy season before summer (2014) and rapid decrease in the air vapor pressure deficit (D) in late summer. Leaf ecophysiological traits in close relationship with gas exchange showed modest seasonal changes and the values were kept at relatively high levels typical in plants with nitrogen fixation under nutrient-poor environments. Stomatal conductance, which was measured at leaf-level measurements and sap flux measurements, showed responses to D, which coincided with the theoretical response for isohydric leaves. A multilayer model, which estimates stand-level transpiration by scaling up the leaf-level data, successfully captured the temporal trends in sap flux, suggesting that major processes were incorporated. Thus, ecophysiological traits of A. firma were characterized by the absence of responses to seasonally changing environments and the transpiration rate was the function of the interannually variable environmental conditions.

    1990-12-16

    The modern hospital is an organization which is influenced by the external environment in which it functions. A major relevant area is the economic environment. In recent years the western world has been facing the challenge of rising costs of health care and an increase in their proportion to the gross national product of most countries. Consequently, hospitals as major providers of health care are under pressure from governments and health insurance companies to cut costs and to "produce" more efficiently. Since hospitals worldwide are finding it hard and painful to function in the new environment in which attitudes to hospitals are changing, a potential managerial-economic crisis may be the next phase. How can the hospital adapt to these changes? First, by adopting managerial attitudes and the tools of the business sector. These include: the strategic planning process, hospital operative autonomy, creating medical-economic responsibility centers as departments, cost-accounting for medical procedures, and case-mix budgeting. Management information systems are necessary during the transition. The hospital information system should include functions at the operative level, such as outpatient visits, and admissions and discharges of patients; and also clinical, diagnostic and laboratory procedures related to the patient case-mix. The second level is a management information system which includes salaries of personnel, case-mix budgeting with variance analysis, prices of procedures and epidemiological data. The authors believe that only the managerial approach combining medical and economic disciplines can meet the challenges of the changing modern economic environment.

    This paper is concern about developing a semantic agreement maintenance method based on semantic distance by calculating the change of local schema or ontology. This approach is important in dynamic and autonomous environment, in which the current approach assumed that agreement or mapping in static environment. The contribution of this research is to develop a framework based on semantic agreement maintenance approach for P2P environment. This framework based on two level hybrid P2P model architecture, which consist of two peer type: (1) super peer that use to register and manage the other peers, and (2) simple peer, as a simple peer, it exports and shares its contents with others. This research develop a model to maintain the semantic agreement in P2P environment, so the current approach which does not have the mechanism to know the change, since it assumed that ontology and local schema are in the static condition, and it is different in dynamic condition.

  2. Climate Change Potential Impacts on the Built Environment and Possible Adaptation Strategies

    Science.gov (United States)

    2014-01-01

    The built environment consists of components that exist at a range of scales from small (e.g., houses, shopping malls) to large (e.g., transportation networks) to highly modified landscapes such as cities. Thus, the impacts of climate change on the built environment may have a multitude of effects on humans and the land. The impact of climate change may be exacerbated by the interaction of different events that singly may be minor, but together may have a synergistic set of impacts that are significant. Also, mechanisms may exist wherein the built environment, particularly in the form of cities, may affect weather and the climate on local and regional scales. Hence, a city may be able to cope with prolonged heat waves, but if this is combined with severe drought, the overall result could be significant or even catastrophic, as accelerating demand for energy to cooling taxes water supplies needed both for energy supply and municipal water needs. This presentation surveys potential climate change impacts on the built environment from the perspective of the National Climate Assessment, and explores adaptation measures that can be employed to mitigate these impacts.

    2012-01-01

    Health care providers in the United States are constantly faced with the enormous challenge of optimizing their revenue cycle to improve their overall financial performance. These challenges keep evolving in both scope and complexity owing to a host of internal and external factors. Furthermore, given the lack of control that health care providers have over external factors, any attempt to successfully optimize the revenue cycle hinges on several critical improvements aimed at realigning the internal factors. This study provides an integrated change management model that aims to reengineer and realign the people-process-technology framework by using the principles of lean and Six Sigma for revenue cycle optimization.

  6. A theoretical quantitative genetic study of negative ecological interactions and extinction times in changing environments

    Directory of Open Access Journals (Sweden)

    Jones Adam G

    2008-04-01

    Full Text Available Abstract Background Rapid human-induced changes in the environment at local, regional and global scales appear to be contributing to population declines and extinctions, resulting in an unprecedented biodiversity crisis. Although in the short term populations can respond ecologically to environmental alterations, in the face of persistent change populations must evolve or become extinct. Existing models of evolution and extinction in changing environments focus only on single species, even though the dynamics of extinction almost certainly depend upon the nature of species interactions. Results Here, I use a model of quantitative trait evolution in a two-species community to show that negative ecological interactions, such as predation and competition, can produce unexpected results regarding time to extinction. Under some circumstances, negative interactions can be expected to hasten the extinction of species declining in numbers. However, under other circumstances, negative interactions can actually increase times to extinction. This effect occurs across a wide range of parameter values and can be substantial, in some cases allowing a population to persist for 40 percent longer than it would in the absence of the species interaction. Conclusion This theoretical study indicates that negative species interactions can have unexpected positive effects on times to extinction. Consequently, detailed studies of selection and demographics will be necessary to predict the consequences of species interactions in changing environments for any particular ecological community.

  7. Feature Optimization for Long-Range Visual Homing in Changing Environments

    Directory of Open Access Journals (Sweden)

    Qidan Zhu

    2014-02-01

    Full Text Available This paper introduces a feature optimization method for robot long-range feature-based visual homing in changing environments. To cope with the changing environmental appearance, the optimization procedure is introduced to distinguish the most relevant features for feature-based visual homing, including the spatial distribution, selection and updating. In the previous research on feature-based visual homing, less effort has been spent on the way to improve the feature distribution to get uniformly distributed features, which are closely related to homing performance. This paper presents a modified feature extraction algorithm to decrease the influence of anisotropic feature distribution. In addition, the feature selection and updating mechanisms, which have hardly drawn any attention in the domain of feature-based visual homing, are crucial in improving homing accuracy and in maintaining the representation of changing environments. To verify the feasibility of the proposal, several comprehensive evaluations are conducted. The results indicate that the feature optimization method can find optimal feature sets for feature-based visual homing, and adapt the appearance representation to the changing environments as well.

    As educational climate strongly affects student achievement, satisfaction and success, it is important to get regular feedback from students on how they experience the educational environment. The Dundee Ready Education Environment Measure (DREEM) Inventory was administered on the same day to all first-, second- and third-year students at the Canadian Memorial Chiropractic College (CMCC) and the students were requested to complete the questionnaire as they were actually experiencing the educational environment at CMCC, and then to say what they would have wanted, or preferred it to be like. Valid returns were received from 146 (95%) first-, 123 (82%) second- and 73 (48%) third-year students (n = 342). The results indicated that the DREEM Inventory used in the Ideal mode, together with the responses in the Actual mode, could be used effectively to determine the dissonance between what they had and what they would have liked to have. It was found that there was a strong similarity in the areas of the educational environment that the different groups of students indicated as falling short of their ideal. The results of this study provided a useful basis for strategic planning and resource utilization.

    Full Text Available The formation of the institutionalism scientific research uniform program (the paradigm is hindered by the absence of the unity concerning the source of institutional restrictions for an individual between the supporters of different directions in the institutionalism. They look for the ways of «institutions endogenization» through defining the place of economic culture in forming institutional environment and the uniform paradigm of modern institutionalism. The author emphasizes the imperfection of neoinstitutionalism conception that focuses on exogenous origin of institutional restrictions for an individual. Making distinction between institutions and customs, they explain institutions as different standards and rules of behavior. Directing the explanation from individuals to institutions they recognize the ontological priority of an individual. A certain institutionally unbiased «natural state» is supposed, provided that institutions appear only as a result of interaction between individuals. Since not only institutions restrict the individuals’ interests but individuals form institutional restrictions as well, the author thinks that the conception of «institution» should take into account its exogenous and endogenous nature. The idea of «institutions endogenization» by D.North, also supported by the author of the article, is the closest to this conception realization. Such explanation of «institution» should provide axiological and attitudinal aspects of scientific knowledge; it should make a person not only a blind doer, but also an active participant of evolutionary changes in economic life. A certain institutional structure is always made up of a set of formal rules and informal restrictions, which are indivisible and specific of every culture. The author defines the economy institutional structure as the system of institutions that through organizing everyday life decreases the uncertainty of individuals’ interaction

    Metal nanoparticles (NPs) scatter and absorb light in precise, designable ways, making them agile candidates for a variety of biomedical applications. When NPs are introduced to a physiological environment and interact with cells, their physicochemical properties can change as proteins adsorb on their surface and they agglomerate within intracellular endosomal vesicles. Since the plasmonic properties of metal NPs are dependent on their geometry and local environment, these physicochemical changes may alter the NPs' plasmonic properties, on which applications such as plasmonic photothermal therapy and photonic gene circuits are based. Here we systematically study and quantify how metal NPs' optical spectra change upon introduction to a cellular environment in which NPs agglomerate within endosomal vesicles. Using darkfield hyperspectral imaging, we measure changes in the peak wavelength, broadening, and distribution of 100-nm spherical gold NPs' optical spectra following introduction to human breast adenocarcinoma Sk-Br-3 cells as a function of NP exposure dose and time. On a cellular level, spectra shift up to 78.6 ± 23.5 nm after 24 h of NP exposure. Importantly, spectra broaden with time, achieving a spectral width of 105.9 ± 11.7 nm at 95% of the spectrum's maximum intensity after 24 h. On an individual intracellular NP cluster (NPC) level, spectra also show significant shifting, broadening, and heterogeneity after 24 h. Cellular transmission electron microscopy (TEM) and electromagnetic simulations of NPCs support the trends in spectral changes we measured. These quantitative data can help guide the design of metal NPs introduced to cellular environments in plasmonic NP-mediated biomedical technologies.

    Tree growth has been reported to increase in response to recent global climate change in controlled and semi-controlled experiments, but few studies have reported response of tree growth to increased temperature and atmospheric carbon dioxide (CO₂) concentration in natural environments. This study addresses how recent global climate change has affected height growth of trembling aspen (Populus tremuloides Michx) and black spruce (Picea mariana Mill B.S.) in their natural environments. We sampled 145 stands dominated by aspen and 82 dominated by spruce over the entire range of their distributions in British Columbia, Canada. These stands were established naturally after fire between the 19th and 20th centuries. Height growth was quantified as total heights of sampled dominant and co-dominant trees at breast-height age of 50 years. We assessed the relationships between 50-year height growth and environmental factors at both spatial and temporal scales. We also tested whether the tree growth associated with global climate change differed with spatial environment (latitude, longitude and elevation). As expected, height growth of both species was positively related to temperature variables at the regional scale and with soil moisture and nutrient availability at the local scale. While height growth of trembling aspen was not significantly related to any of the temporal variables we examined, that of black spruce increased significantly with stand establishment date, the anomaly of the average maximum summer temperature between May-August, and atmospheric CO₂ concentration, but not with the Palmer Drought Severity Index. Furthermore, the increase of spruce height growth associated with recent climate change was higher in the western than in eastern part of British Columbia. This study demonstrates that the response of height growth to recent climate change, i.e., increasing temperature and atmospheric CO₂ concentration, did not only differ with tree species, but

    This paper presents and demonstrates a spatial framework for the application of strategic environmental assessment (SEA) in the context of change analysis for urban wetland environments. The proposed framework is focused on two key stages of the SEA process: scoping and environmental baseline assessment. These stages are arguably the most information-intense phases of SEA and have a significant effect on the quality of the SEA results. The study aims to meet the needs for proactive frameworks to assess and protect wetland habitat and services more efficiently, toward the goal of advancing more intelligent urban planning and development design. The proposed framework, adopting geographic information system and remote sensing tools and applications, supports the temporal evaluation of wetland change and sustainability assessment based on landscape indicator analysis. The framework was applied to a rapidly developing urban environment in the City of Saskatoon, Saskatchewan, Canada, analyzing wetland change and land-use pressures from 1985 to 2011. The SEA spatial scale was rescaled from administrative urban planning units to an ecologically meaningful area. Landscape change assessed was based on a suite of indicators that were subsequently rolled up into a single, multi-dimensional, and easy to understand and communicate index to examine the implications of land-use change for wetland sustainability. The results show that despite the recent extremely wet period in the Canadian prairie region, land-use change contributed to increasing threats to wetland sustainability.

    1. Organism–environment models are used widely in conservation. The degree to which they are useful for informing conservation decisions – the conservation relevance of these relations – is important because lack of relevance may lead to misapplication of scarce conservation resources or failure to resolve important conservation dilemmas. Even when models perform well based on model fit and predictive ability, conservation relevance of associations may not be clear without also knowing the magnitude and variability of predicted changes in response variables. 2. We introduce a method for evaluating the conservation relevance of organism–environment relations that employs confidence intervals for predicted changes in response variables. The confidence intervals are compared to a preselected magnitude of change that marks a threshold (trigger) for conservation action. To demonstrate the approach, we used a case study from the Chihuahuan Desert involving relations between avian richness and broad-scale patterns of shrubland. We considered relations for three winters and two spatial extents (1- and 2-km-radius areas) and compared predicted changes in richness to three thresholds (10%, 20% and 30% change). For each threshold, we examined 48 relations. 3. The method identified seven, four and zero conservation-relevant changes in mean richness for the 10%, 20% and 30% thresholds respectively. These changes were associated with major (20%) changes in shrubland cover, mean patch size, the coefficient of variation for patch size, or edge density but not with major changes in shrubland patch density. The relative rarity of conservation-relevant changes indicated that, overall, the relations had little practical value for informing conservation decisions about avian richness. 4. The approach we illustrate is appropriate for various response and predictor variables measured at any temporal or spatial scale. The method is broadly applicable across ecological

    Full Text Available Introduction. The epidemic of obesity is a multifaceted public health issue. Positive policy and environmental changes are needed to support healthier eating and increased physical activity. Methods. StrongWomen Change Clubs (SWCCs were developed through an academic-community research partnership between researchers at Cornell University and Tufts University and community partners (cooperative extension educators in rural towns in seven U.S. states. Extension educators served as the local leader and each recruited 10–15 residents to undertake a project to improve some aspect of the nutrition or physical activity environment. Most residents had limited (or no experience in civic engagement. At 6 and 12 months after implementation, the research team conducted key informant interviews with SWCC leaders to capture their perceptions of program process, benchmark achievement, and self-efficacy. Results. At 12 months, each SWCC had accomplished one benchmark; the majority had completed three or more benchmarks. They described common processes for achieving benchmarks such as building relationships and leveraging stakeholder partnerships. Barriers to benchmark achievement included busy schedules and resistance to and slow pace of change. Conclusion. Findings suggest that community change initiatives that involve stakeholders, build upon existing activities and organizational resources, and establish feasible timelines and goals can successfully catalyze environmental change.

    University College London is currently developing a large-scale multi-camera system for dimensional control tasks in manufacturing, including part machining, assembly and tracking, as part of the Light Controlled Factory project funded by the UK Engineering and Physical Science Research Council. In parallel, as part of the EU LUMINAR project funded by the European Association of National Metrology Institutes, refraction models of the atmosphere in factory environments are being developed with the intent of modelling and eliminating the effects of temperature and other variations. The accuracy requirements for both projects are extremely demanding, so accordingly improvements in the modelling of both camera imaging and the measurement environment are essential. At the junction of these two projects lies close range camera calibration. The accurate and reliable calibration of cameras across a realistic range of atmospheric conditions in the factory environment is vital in order to eliminate systematic errors. This paper demonstrates the challenge of experimentally isolating environmental effects at the level of a few tens of microns. Longer lines of sight promote the use and calibration of a near perfect perspective projection from a Kern 75mm lens with maximum radial distortion of the order of 0.5m. Coordination of a reference target array, representing a manufactured part, is achieved to better than 0.1mm at a standoff of 8m. More widely, results contribute to better sensor understanding, improved mathematical modelling of factory environments and more reliable coordination of targets to 0.1mm and better over large volumes.

    2013-06-01

    Policies designed to increase public engagement with biodiversity advocate increased education across a range of educational contexts. Evidence of the benefits of learning in natural environments (LINE) continues to be amassed. LINE affords direct benefits as diverse as educational, health and psychological and indirect benefits ranging from social to financial. Research into the value of LINE has failed to address the full range of benefits. Instead, there has been a narrow focus on easily measurable outcomes and a desire to seek answers to simplistic questions such as "does LINE raise standards more than learning in the classroom?" An attempt is made to outline the full range of benefits which are available to all school students. The outcomes include: benefits to individual participants (knowledge and understanding; skills; attitudes and behaviours; health and well-being; self-efficacy and self-worth); benefits to teachers, schools and the wider community, and benefits to the natural environment sector. Several barriers exist to the effective delivery of LINE. These barriers can be grouped into those that challenge the natural environment sector and those that challenge schools. The challenges facing the sector include a lack of a coordinated effective approach to working with schools at a local level. The challenges facing schools include those frequently mentioned such as the risk of accidents, cost and curriculum pressures. However, another set of challenges exists, at local, institutional and personal levels. These challenges include teachers' confidence, self-efficacy and their access to training in using natural environments close to the school and further afield.

    Purpose: To quantitatively assess changes in computed tomography (CT)–defined normal lung tissue density after conventional and hypofractionated radiation therapy (RT). Methods and Materials: The pre-RT and post-RT CT scans from 118 and 111 patients receiving conventional and hypofractionated RT, respectively, at 3 institutions were registered to each other and to the 3-dimensional dose distribution to quantify dose-dependent changes in normal lung tissue density. Dose-response curves (DRC) for groups of patients receiving conventional and hypofractionated RT were generated for each institution, and the frequency of density changes >80 Hounsfield Units (HU) was modeled depending on the fractionation type using a Probit model for different follow-up times. Results: For the pooled data from all institutions, there were significant differences in the DRC between the conventional and hypofractionated groups; the respective doses resulting in 50% complication risk (TD{sub 50}) were 62 Gy (95% confidence interval [CI] 57-67) versus 36 Gy (CI 33-39) at <6 months, 48 Gy (CI 46-51) versus 31 Gy (CI 28-33) at 6-12 months, and 47 Gy (CI 45-49) versus 35 Gy (32-37) at >12 months. The corresponding m values (slope of the DRC) were 0.52 (CI 0.46-0.59) versus 0.31 (CI 0.28-0.34) at <6 months, 0.46 (CI 0.42-0.51) versus 0.30 (CI 0.26-0.34) at 6-12 months, and 0.45 (CI 0.42-0.50) versus 0.31 (CI 0.27-0.35) at >12 months (P<.05 for all comparisons). Conclusion: Compared with conventional fractionation, hypofractionation has a lower TD{sub 50} and m value, both suggesting an increased degree of normal tissue density sensitivity with hypofractionation.

    There is growing evidence that projected climate change has the potential to significantly affect public health. In the UK, much of this impact is likely to arise by amplifying existing risks related to heat exposure, flooding, and chemical and biological contamination in buildings. Identifying the health effects of climate change on the indoor environment, and risks and opportunities related to climate change adaptation and mitigation, can help protect public health. We explored a range of health risks in the domestic indoor environment related to climate change, as well as the potential health benefits and unintended harmful effects of climate change mitigation and adaptation policies in the UK housing sector. We reviewed relevant scientific literature, focusing on housing-related health effects in the UK likely to arise through either direct or indirect mechanisms of climate change or mitigation and adaptation measures in the built environment. We considered the following categories of effect: (i) indoor temperatures, (ii) indoor air quality, (iii) indoor allergens and infections, and (iv) flood damage and water contamination. Climate change may exacerbate health risks and inequalities across these categories and in a variety of ways, if adequate adaptation measures are not taken. Certain changes to the indoor environment can affect indoor air quality or promote the growth and propagation of pathogenic organisms. Measures aimed at reducing greenhouse gas emissions have the potential for ancillary public health benefits including reductions in health burdens related heat and cold, indoor exposure to air pollution derived from outdoor sources, and mould growth. However, increasing airtightness of dwellings in pursuit of energy efficiency could also have negative effects by increasing concentrations of pollutants (such as PM2.5, CO and radon) derived from indoor or ground sources, and biological contamination. These effects can largely be ameliorated by mechanical

    This paper is mainly devoted to the flocking of a class of swarm with fixed topology in a changing environment.Firstly,the controller for each agent is proposed by employing the error terms between the state of the agent and the average state of its neighbors.Secondly,a sufficient condition for the swarm to achieve flocking is presented under assumptions that the gradient of the environment is bounded and the initial position graph is connected.Thirdly,as the environment is a plane,it is further proved that the velocity of each agent finally converges to the velocity of the swarm center although not one agent knows where the center of the group is.Finally,numerical examples are included to illustrate the obtained results.

    2002-07-01

    The introduction of market rules in a electricity supply industry characterized by a vertically integrated monopoly and public ownership is not inherently doomed to failure if characteristics of the reform or other elements of industrial structures give room for enforcing market-rules. The organisation of the French ESI in a public monopoly was deeply rooted in French institutional peculiarities. The paper analyses how the governmental goal of preserving the national champion EDF have had two paradoxical effects in favour of competition development and the building of safeguards for the entrants: the creation of a credible regulatory governance structure with effective power of control on the network access, and which promoted market-rules and the creation of a power exchange for balancing the incumbent dominant position; and the enforcement of the credibility of the regulatory framework by the self control of the incumbent on the use of its dominant position and on the capture of the regulator. This two effects results from the influence of the European institutional environment which is superposed to the national one, in particular under the intensive scrutiny of the European Commission, on a model far behind the competitive model. The paper concludes to the originality of such an institutional model: a permanent regulatory threat on the incumbent for balancing the effects of public property and integration of industrial structures.

  6. Evolution of Population with Sexual and Asexual Reproduction in Changing Environment

    Science.gov (United States)

    He, Mingfeng; Yu, Changliang; Ruan, Hongbo; Yao, Lei

    Using a lattice model based on Monte Carlo simulations, we study the role of the reproduction pattern on the fate of an evolving population. Each individual is under the selection pressure from the environment and random mutations. The habitat ("climate") is changing periodically. Evolutions of populations following two reproduction patterns are compared, asexual and sexual. We show, via Monte Carlo simulations, that sexual reproduction by keeping more diversified populations gives them better chances to adapt themselves to the changing environment. However, in order to obtain a greater chance to mate, the birth rate should be high. In the case of low birth rate and high mutation probability there is a preference for the asexual reproduction.

    Animals must contend with an ever-changing environment. Social animals, especially eusocial insects such as ants and bees, rely heavily on communication for their success. However, in a changing environment, communicated information can become rapidly outdated. This is a particular problem for pheromone trail using ants, as once deposited pheromones cannot be removed. Here, we study the response of ant foragers to an environmental change. Ants were trained to one feeder location, and the feeder was then moved to a different location. We found that ants responded to an environmental change by strongly upregulating pheromone deposition immediately after experiencing the change. This may help maintain the colony's foraging flexibility, and allow multiple food locations to be exploited simultaneously. Our treatment also caused uncertainty in the foragers, by making their memories less reliable. Ants which had made an error but eventually found the food source upregulated pheromone deposition when returning to the nest. Intriguingly, ants on their way towards the food source downregulated pheromone deposition if they were going to make an error. This may suggest that individual ants can measure the reliability of their own memories and respond appropriately.

    Catastrophic flooding resulting from extreme meteorological events has occurred more frequently and drawn great attention in recent years in China. In coastal areas, extreme precipitation and storm tide are both inducing factors of flooding and therefore their joint probability would be critical to determine the flooding risk. The impact of storm tide or changing environment on flooding is ignored or underestimated in the design of drainage systems of today in coastal areas in China. This paper investigates the joint probability of extreme precipitation and storm tide and its change using copula-based models in Fuzhou City. The change point at the year of 1984 detected by Mann-Kendall and Pettitt's tests divides the extreme precipitation series into two subsequences. For each subsequence the probability of the joint behavior of extreme precipitation and storm tide is estimated by the optimal copula. Results show that the joint probability has increased by more than 300% on average after 1984 (α = 0.05). The design joint return period (RP) of extreme precipitation and storm tide is estimated to propose a design standard for future flooding preparedness. For a combination of extreme precipitation and storm tide, the design joint RP has become smaller than before. It implies that flooding would happen more often after 1984, which corresponds with the observation. The study would facilitate understanding the change of flood risk and proposing the adaption measures for coastal areas under a changing environment.

  14. A Governing Framework for Climate Change Adaptation in the Built Environment

    Full Text Available Developing an approach to governing adaptation to climate change is severely hampered by the dictatorship of the present when the needs of future generations are inadequately represented in current policy making. We posit this problem as a function of the attributes of adaptation policy making, including deep uncertainty and nonstationarity, where past observations are not reliable predictors of future outcomes. Our research links organizational decision-making attributes with adaptation decision making and identifies cases in which adaptation actions cause spillovers, free riding, and distributional impacts. We develop a governing framework for adaptation that we believe will enable policy, planning, and major long-term development decisions to be made appropriately at all levels of government in the face of the deep uncertainty and nonstationarity caused by climate change. Our framework requires that approval of projects with an expected life span of 30 years or more in the built environment include minimum building standards that integrate forecasted climate change impacts from the Intergovernmental Panel on Climate Change (IPCC intermediate scenario. The intermediate IPCC scenario must be downscaled to include local or regional temperature, water availability, sea level rise, susceptibility to forest fires, and human habitation impacts to minimize climate-change risks to the built environment. The minimum standard is systematically updated every six years to facilitate learning by formal and informal organizations. As a minimum standard, the governance framework allows jurisdictions to take stronger actions to increase their climate resilience and thus maintain system flexibility.

    2015-01-01

    Loess-Paleosol deposits drape >500,000 km2 of eastern China, spanning environments from the humid, monsoon-influenced regions near the coast to the arid, westerlies-dominated regions inland. Sections, up to hundreds of meters thick, are exposed in deeply incised river valleys and can be accessed as well by drilling. Combined, the high sedimentation rates and extensive geographic coverage make these sections unique among global terrestrial sediment archives. The Chinese loess-paleosol sequences, and the arid interior regions to the northwest, record diverse aspects of geologic and environmental change ranging from the tectonic evolution of the Tibetan Plateau (106 year time scale) through glacial-interglacial scale changes in global ice volume and greenhouse gasses (105 year time scale) on down through the orbital (104 years) to millennial and centennial scale events (103-102 year) relevant to the underpinnings of human interactions with changing environmental pressures. 'Late Cenozoic Climate Chang in Asia: Loess, Monsoon and Monsoon-arid Environment Evolution' is a timely contribution that synthesizes findings derived from the extensive work in these areas, places the findings in the broader context of global climate change and helps to define avenues for future research.

  16. 3. Neural changes in different gravity and ecophysiological environments - A survey

    Slenzka, K.

    Neural changes or neuronal plasticity occur after and during different stimulations and inputs in general. Gravity is one major input to the brain transferred from the vestibular system. However, often also direct effects of gravity on the cellular level are discussed. Our group was investigating the influence of different gravity environments on a large variety of neuronal enzymes in the developing fish brain. Long-term space travel or bases on Moon and Mars will have to deal not only with neural changes based on the different gravity environment, but also with potential negative or even toxic changes in the respective life support system. Our goal is now to identify reported enzyme activity changes in the brain based for example on potential toxic drugs or endocrine disruptors in combination with gravity induced changes. In this paper a survey will be undertaken discussing recent results obtained in ecotoxicology, gravitational biology combined with new data from our group regarding potential differences in brain glucose-6-phosphate dehydrogenase of medaka and zebrafish.

    Manmade climate change has expressed a plethora of complex effects on Earth's biogeochemical compartments. Climate change may also affect the mobilisation of natural metal sources, with potential ecological consequences beyond mountains' geographical limits; however, this question has remained largely unexplored. We investigated this by analysing a number of key climatic factors in relationship with trace metal accumulation in the sediment core of a Pyrenean lake. The sediment metal contents showed increasing accumulation trend over time, and their levels varied in step with recent climate change. The findings further revealed that a rise in the elevation of freezing level, a general increase in the frequency of drier periods, changes in the frequency of winter freezing days and a reducing snow cover since the early 1980s, together are responsible for the observed variability and augmented accumulation of trace metals. Our results provide clear evidence of increased mobilisation of natural metal sources - an overlooked effect of climate change on the environment. With further alterations in climate equilibrium predicted over the ensuing decades, it is likely that mountain catchments in metamorphic areas may become significant sources of trace metals, with potentially harmful consequences for the wider environment.

    2001-09-01

    The National Institute of Mental Health Multisite HIV Prevention Trial was a trial of an intervention to reduce sexual HIV risk behaviors among 3,706 low-income at-risk men and women at 7 U.S. research sites. The intervention, based on social-cognitive theory and designed to influence behavior change by improving expected outcomes of condom use and increasing knowledge, skills, and self-efficacy to execute safer sex behaviors, was effective relative to a control condition in reducing sexual risk behavior. At 3 months after completion of the intervention, measures of these potential mediators were higher in the intervention than in the control condition. Although the effect of the intervention on sexual risk behavior was significantly reduced when the variables were controlled statistically, supporting the hypothesis of their mediation of the intervention effect, most of the effect remained unexplained, indicating the influence of unmeasured factors on outcome.

    Full Text Available The features of complexity are ever more present in modern organizations and in environments in which they operate, trying to survive and be as competitive as possible. In the processes of, the so-called emergence, the formal organizational structure, designed purposefully and with a plan, is going through a change due to complexity and the need for adaptation. As a result, there is a variety of new informal groups. At the same time, the intended structural changes and business process changes occur because of the perception that the leadership and senior organizational management have of the strategic situation. Managers in modern organizations often use business intelligence (BI systems when making important business decisions. These systems offer support to the decision-making by gathering and processing relevant data and information about the company performance, but also about the data on conditions in close and remote environment. A modern company is characterized by the complex adaptive system, but the environment in which it operates together with other business subjects (agents is also complex. Consequently, the requirements for appropriate or optimal decisions and successfully completed activities are hard to meet. Given that expected future events and circumstances often occur in nonlinear mechanisms, the decisions made by following the models of traditional predicting and planning are not satisfactory. This calls for new approaches to decision making and acting.

    Changes in school nutrition and physical activity policies and environments are important to combat childhood obesity. Arkansas Act 1220 of 2003 was among the first and most comprehensive statewide legislative initiatives to combat childhood obesity through school-based change. Annual surveys of principals and superintendents have been analyzed to document substantial and important changes in school environments, policies, and practices. For example, results indicate that schools are more likely to require that healthy options be provided for student parties (4.5% in 2004, 36.9% in 2008; P students in cafeterias (white milk: 26.1% in 2004, 41.0% in 2008, P chocolate milk: 9.0% in 2004, 24.0% in 2008, P changes were noted in foods and beverages offered in the cafeteria, in classrooms, and at school events, as well as in fund-raising and physical activity practices. A significant number of school districts have modified physical education requirements for elementary schools and developed policies prohibiting the use of physical activity as a punishment. We conclude that Arkansas Act 1220 of 2003 is associated with a number of changes in school environments and policies, resulting from both statewide and local initiatives spawned by the Act.

    Full Text Available The article represents the author's view on the issue of formation of innovative environment in the oil and gas industry through clustering. The main task of the author is, on the one hand, clusters’ role justification in optimization of organizational structure of regional fuel and energy complex. On the other hand, it is a justification of the state's functions in ensuring the intensification of innovation. To solve this complex problem the author explores the approaches to the definition of "cluster", adapting existing theories to clustering of the regional to the oil and gas sector. There are the structural-logic "Competitive diamond" Russian oil cluster "and" Competitive diamond "oil cluster Russia." The author 'classification of innovations in the energy sector is developed. The question of revitalization of the state’s efforts to build a favorable innovation environment was considered based on several logical promises. The first, public policy objectives to stimulate investment in innovation are substantiated. Second, we studied directions of transformation of the global energy market and their impact on the economic security of Russia as oil exporters. Separately, the emphasis is placed on fiscal policy in the energy sector

  3. Constitutive versus responsive gene expression strategies for growth in changing environments.

    Directory of Open Access Journals (Sweden)

    Nico Geisel

    Full Text Available Microbes respond to changing environments by adjusting gene expression levels to the demand for the corresponding proteins. Adjusting protein levels is slow, consequently cells may reach the optimal protein level only by a time when the demand changed again. It is therefore not a priori clear whether expression "on demand" is always the optimal strategy. Indeed, many genes are constitutively expressed at intermediate levels, which represents a permanent cost but provides an immediate benefit when the protein is needed. Which are the conditions that select for a responsive or a constitutive expression strategy, what determines the optimal constitutive expression level in a changing environment, and how is the fitness of the two strategies affected by gene expression noise? Based on an established model of the lac- and gal-operon expression dynamics, we study the fitness of a constitutive and a responsive expression strategy in time-varying environments. We find that the optimal constitutive expression level differs from the average demand for the gene product and from the average optimal expression level; depending on the shape of the growth rate function, the optimal expression level either provides intermediate fitness in all environments, or maximizes fitness in only one of them. We find that constitutive expression can provide higher fitness than responsive expression even when regulatory machinery comes at no cost, and we determine the minimal response rate necessary for "expression on demand" to confer a benefit. Environmental and inter-cellular noise favor the responsive strategy while reducing fitness of the constitutive one. Our results show the interplay between the demand-frequency for a gene product, the genetic response rate, and the fitness, and address important questions on the evolution of gene regulation. Some of our predictions agree with recent yeast high throughput data, for others we propose the experiments that are needed

    Full Text Available Simon recognized the limitations of the classical normative decision theory and established descriptive theory. His concept of bounded rationality and administrative behavior was a big step ahead, but the world has changed dramatically since then. Multiple, continuous changes have become normal, which brings up new problems on the decision maker’s and on the organization’s level as well. It became usual that the decision maker is not able to define preferences for lack of knowledge and have to learn or delegate much more frequently than before. In the same time the organization should be more resilient or nimble in this ever-changing environment. The authors outline a research agenda on both levels: some about the continuous learning and frequent delegating, and some about the HRM and IT-management issues of organizational nimbleness.

  8. Planning safer suburbs: do changes in the built environment influence residents' perceptions of crime risk?

    A growing body of evidence has reiterated the negative impacts that crime and perceptions of insecurity can have on the health and wellbeing of local residents. Strategies that reduce residents' perceived crime risk may contribute to improved health outcomes; however interventions require a better understanding of the neighbourhood influences on residents perceptions of crime and safety. We examined the impact of changes in the objective built environment following relocation on changes in residents' perceived crime risk for participants in a longitudinal study of people moving to new neighbourhoods in Perth, Western Australia (n = 1159). They completed a questionnaire before moving to their new neighbourhood, and again 36 months after relocation. Individual-level objective environmental measures were generated at both time points using Geographic Information Systems, focussing on the characteristics that comprise a 'walkable neighbourhood'. Linear regression models examined the influence of objective environmental changes between the two environments on perceived crime risk, with progressive adjustment for other change variables (i.e., perceptions of the physical and social environment, reported crime). We found that increases in the proportion of land allocated to shopping/retail land-uses increased residents' perceived crime risk (β = 11.875, p = 0.001), and this relationship remained constant, despite controlling for other influences on perceived crime risk (β = 9.140, p = 0.004). The findings highlight an important paradox: that the neighbourhood characteristics known to enhance one outcome, such as walking, may negatively impact another. In this instance, the 'strangers' that retail destinations attract to a neighbourhood may be interpreted by locals as a threat to safety. Thus, in areas with more retail destinations, it is vital that other environmental strategies be employed to balance any negative effects that retail may have on residents' perceptions of

    Coastal embayments are at risk of impacts by climate change drivers such as ocean warming, sea level rise and alteration in precipitation regimes. The response of the ecosystem to these drivers is highly dependent on their magnitude of change, but also on physical characteristics such as bay morphology and river discharge, which play key roles in water residence time and hence estuarine functioning. These considerations are especially relevant for bivalve aquaculture sites, where the cultured biomass can alter ecosystem dynamics. The combination of climate change, physical and aquaculture drivers can result in synergistic/antagonistic and nonlinear processes. A spatially explicit model was constructed to explore effects of the physical environment (bay geomorphic type, freshwater inputs), climate change drivers (sea level, temperature, precipitation) and aquaculture (bivalve species, stock) on ecosystem functioning. A factorial design led to 336 scenarios (48 hydrodynamic × 7 management). Model outcomes suggest that the physical environment controls estuarine functioning given its influence on primary productivity (bottom-up control dominated by riverine nutrients) and horizontal advection with the open ocean (dominated by bay geomorphic type). The intensity of bivalve aquaculture ultimately determines the bivalve-phytoplankton trophic interaction, which can range from a bottom-up control triggered by ammonia excretion to a top-down control via feeding. Results also suggest that temperature is the strongest climate change driver due to its influence on the metabolism of poikilothermic organisms (e.g. zooplankton and bivalves), which ultimately causes a concomitant increase of top-down pressure on phytoplankton. Given the different thermal tolerance of cultured species, temperature is also critical to sort winners from losers, benefiting Crassostrea virginica over Mytilus edulis under the specific conditions tested in this numerical exercise. In general, it is

    Over 150 research articles relating three multi-disciplinary topics (air pollution, climate change and civil engineering structures) are reviewed to examine the footprints of air pollution and changing environment on the sustainability of building and transport structures (referred as built infrastructure). The aim of this review is to synthesize the existing knowledge on this topic, highlight recent advances in our understanding and discuss research priorities. The article begins with the background information on sources and emission trends of global warming (CO(2), CH(4), N(2)O, CFCs, SF(6)) and corrosive (SO(2), O(3), NO(X)) gases and their role in deterioration of building materials (e.g. steel, stone, concrete, brick and wood) exposed in outdoor environments. Further section covers the impacts of climate- and pollution-derived chemical pathways, generally represented by dose-response functions (DRFs), and changing environmental conditions on built infrastructure. The article concludes with the discussions on the topic areas covered and research challenges. A comprehensive inventory of DRFs is compiled. The case study carried out for analysing the inter-comparability of various DRFs on four different materials (carbon steel, limestone, zinc and copper) produced comparable results. Results of another case study revealed that future projected changes in temperature and/or relatively humidity are expected to have a modest effect on the material deterioration rate whereas changes in precipitation were found to show a more dominant impact. Evidences suggest that both changing and extreme environmental conditions are expected to affect the integrity of built infrastructure both in terms of direct structural damage and indirect losses of transport network functionality. Unlike stone and metals, substantially limited information is available on the deterioration of brick, concrete and wooden structures. Further research is warranted to develop more robust and

    Full Text Available This article compares various elements of Ibn Khaldūn’s and Douglass C. North’s thoughts on the role of institutions in influencing or forcing economic change. There are a number of interesting similarities in ideas, thoughts, approaches, and methodologies, which prove that New Institutional Economics may actually mirror much of (and can benefit from Ibn Khaldūn’s fourteenth century ideas than was previously thought. Both Ibn Khaldūn’s continuum of badāwah to ḥaḍārah and North’s theory on changes from informal to formal institutions lead to the same fundamental conclusions: (i change is incremental as it is a result in small cumulative changes in the cost-benefit outcomes of the market agents over time, and therefore (ii economic performance inevitably depends on the existence and effectiveness of formal institutions that alter those outcomes. It is also noted that ‘aṣabiyyah or group feeling, another cornerstone of Ibn Khaldūn’s thought, corresponds perfectly to North’s treatise that social cohesion and institutional efficiency are more important than the amount of resource endowment in bringing about economic development and change. In addition, Ibn Khaldūn’s views on the government’s commercial activities are reviewed in the study in light of North’s transaction costs and property rights framework.

    In their comparison of chronic schizophrenic patients in three British mental hospitals in 1960, Wing and Brown found a strong association between the poverty of the social environment and the severity of 'clinical poverty' (blunted affect, poverty of speech, and social withdrawal). Between 1960 and 1968 the social environments of all three hospitals improved and a weak causal relationship between social poverty and clinical poverty was reported in a proportion of patients. Using the same assessment instruments as Wing and Brown, the present study re-examined the relationship between social and clinical poverty in the long-stay schizophrenic population of a fourth British mental hospital in 1990. The association found between social and clinical poverty was much weaker than in 1960. Reluctance on the part of patients to be discharged from the institution was unrelated to length of stay. There was no significant difference in severity of illness between the patients in the present study and those in the earlier study. However, patients in the former group spent more time doing nothing than those in the hospital with the most understimulating environment three decades before, with four-fifths doing nothing for over five hours a day, despite a greatly increased ratio of nurses to patients.

    2015-10-01

    Explaining policy change has been one of the major concerns of the health care politics and policy development literature. This article aims to explain the specific dynamics of large-scale reforms introduced within the framework of the Health Transformation Program in Turkey. It argues that confluence of the three streams - problem, policy, and politics - with the exceptional political will of the Justice and Development Party's (JDP) leaders opened up a window of opportunity for a large-scale policy change. The article also underscores the contribution of recent ideational perspectives that help explain "why" political actors in Turkey would focus on health care reform, given that there are a number of issues waiting to be addressed in the policy agenda. Examining how political actors framed problems and policies deepens our understanding of the content of the reform initiatives as well as the construction of the need to reform. The article builds on the insights of both the ideational and institutionalist perspectives when it argues that the interests, aspirations, and fears of the JDP, alongside the peculiar characteristics of the institutional context, have shaped its priorities and determination to carry out this reform initiative.

    To promote the development of a culture and a professional practice based on "evidence of effectiveness", the IOSI Nursing Officer instituted a specific Unit which decided to establish its own lines of action based on the results of an internal investigation conducted among nurses employed within IOSI, with reference to the model of action research. In July 2010, a semi-structured questionnaire self compiled was sent to all nurses to find out their opinions and experiences on EBP and nursing research, to recognize their proposals, and willingness to be part of an internal network. 63 out of 98 questionnaire were filled in. Several nurses have knowledge and experience in these fields, but change their professional behavior especially under pressure from the external environment, rather than by autonomous choice. They consider EBP substantially useful, but difficult to implement especially without their direct involvement. Two third of the sample have felt the need of EBP during their professional activity and there is a general willingness to develop nursing research (56%) and/or play an active role of "referent" on these issues within own Unit (35%). The survey showed that at IOSI there is a favorable substrate for EBP and nursing research (for basic knowledge and availability). The data collected have served to define internal lines of action in a narrow relationship with the clinical areas, according to the model of action research. It is a process that requires vision, coordinated efforts, perseverance and time.

    The PULSE Vision & Change Rubrics, version 1.0, assess life sciences departments' progress toward implementation of the principles of the Vision and Change report. This paper reports on the development of the rubrics, their validation, and their reliability in measuring departmental change aligned with the Vision and Change recommendations. The rubrics assess 66 different criteria across five areas: Curriculum Alignment, Assessment, Faculty Practice/Faculty Support, Infrastructure, and Climate for Change. The results from this work demonstrate the rubrics can be used to evaluate departmental transformation equitably across institution types and represent baseline data about the adoption of the Vision and Change recommendations by life sciences programs across the United States. While all institution types have made progress, liberal arts institutions are farther along in implementing these recommendations. Generally, institutions earned the highest scores on the Curriculum Alignment rubric and the lowest scores on the Assessment rubric. The results of this study clearly indicate that the Vision & Change Rubrics, version 1.0, are valid and equitable and can track long-term progress of the transformation of life sciences departments. In addition, four of the five rubrics have broad applicability and can be used to evaluate departmental transformation by other science, technology, engineering, and mathematics disciplines.

Here, we investigated the size of the brain in hatcheryreared Atlantic salmon Salmo salar kept at standard (high) and reduced (low) tank densities. In contrast to our predictions, we found that fish reared at high density had larger dry mass of cerebellum......Lowered rearing density has repeatedly been shown to increase the performance of hatchery-reared salmonids stocked into natural environments. One possible mechanism for this pattern could be that lower densities enhance brain development, which has been shown to be the case in other hatchery...... the opposite pattern was observed for telencephalon. Overall, these results reveal substantial brain plasticity depending on the surrounding environment as well as ontogenetic adaptive changes in the brain of the Atlantic salmon...

    Diverse biological networks exhibit universal features distinguished from those of random networks, calling much attention to their origins and implications. Here we propose a minimal evolution model of Boolean regulatory networks, which evolve by selectively rewiring links towards enhancing adaptability to a changing environment and stability against dynamical perturbations. We find that sparse and heterogeneous connectivity patterns emerge, which show qualitative agreement with real transcriptional regulatory networks and metabolic networks. The characteristic scaling behavior of stability reflects the balance between robustness and flexibility. The scaling of fluctuation in the perturbation spread shows a dynamic crossover, which is analyzed by investigating separately the stochasticity of internal dynamics and the network structure differences depending on the evolution pathways. Our study delineates how the ambivalent pressure of evolution shapes biological networks, which can be helpful for studying general complex systems interacting with environments.

    管理层持股激励是当前理论和实务界关注的一种重要的公司治理机制。以往的研究往往研究激励契约本身或激励契约的经济后果。然而.激励契约有效发挥的重要前提是该契约与外部制度环境相适应。本文运用制度经济学的基本原理.实证检验了股权分置改革、国有控股、产品市场竞争这三种外部制度环境对管理层持股激励效率的影响。实证研究发现:①股权分置改革前,实施管理层持股激励的公司其经营绩效相比控制样本没有显著差异:股权分置改革后。其经营绩效显著高于控制样本。②国有控股企业采用管理层持股在股改前激励效应不显著.但是,在股改后激励效应显著提高。③在竞争性的产品市场,管理层持股激励有明显的正效应;而在垄断性市场中,管理层持股的激励效应较弱。本文的研究结果表明。制度环境是管理层持股激励发挥作用的重要前提.在实施管理层持股激励的同时。还应重视相关制度环境的改善,使管理层持股发挥应有的激励效应。%Managerial ownership incentive is an important corporate governance mechanism concerned by theory and practice fields. Previous studies tend to study the economic consequences of the incentive contract or the incentive contract itself. However, the incentives play effectively only adapted to the external institutional environment. This paper examines the efficiency of managerial ownership incentive in three institutional environments: non-tradable share reform, state-holding and product market competition using the basic principles of institutional economics from the perspective of effective contract. Empirical study finds that: First, the small differences in financial performance between companies with managerial ownership and those without in controls samples turned significant after the non-tradable share reform; Second, the

    Serious soil erosion has made the eco-environment fragile in the Loess Plateau. Based on the 10-year da-ta observed from 1989 to 1998 in the Ziwuling Survey Station in loess hilly region, the eco-environment change and soil erosion process in reclaimed forestland were studied in this paper. The results showed that the intensity of man-made soil erosion caused by forestland reclamation was 1000 times more than that of the natural erosion. From the analysis of soil physical and mechanical properties, in the 10th year after forestland was reclaimed, the clay content and physical clay content decreased 2.74 percentage point and 3.01 percentage point respectively, the >0.25mm water-stable aggregate content decreased 31.59 percentage point, the soil bulk density increased and soil shear strength de-creased, all of which were easier to cause soil erosion. The correlation analysis showed that >0.25mm waterstable ag-gregate content was the key factor affecting soil erosion, and the secondary factors were soil coarse grain and soil shear strength. The relation between the >0.25mm waterstable aggregate content, the soil sheer strength and the soil erosion intensity were analyzed, which showed that the first year and the seventh erosion year were the turn years of the soil erosion intensity after the forestland was reclaimed, revealed that the change ofeco-environment was the main cause to accelerate soil erosion, and the worse environment caused soil erosion to be serious rapidly.

  3. Robust online belief space planning in changing environments: Application to physical mobile robots

    © 2014 IEEE. Motion planning in belief space (under motion and sensing uncertainty) is a challenging problem due to the computational intractability of its exact solution. The Feedback-based Information RoadMap (FIRM) framework made an important theoretical step toward enabling roadmap-based planning in belief space and provided a computationally tractable version of belief space planning. However, there are still challenges in applying belief space planners to physical systems, such as the discrepancy between computational models and real physical models. In this paper, we propose a dynamic replanning scheme in belief space to address such challenges. Moreover, we present techniques to cope with changes in the environment (e.g., changes in the obstacle map), as well as unforeseen large deviations in the robot\\'s location (e.g., the kidnapped robot problem). We then utilize these techniques to implement the first online replanning scheme in belief space on a physical mobile robot that is robust to changes in the environment and large disturbances. This method demonstrates that belief space planning is a practical tool for robot motion planning.

    Exposure to an enriched environment promotes neurochemical, structural and neurophysiological changes in the brain and is associated with enhanced synaptic plasticity and improved hippocampal-dependent learning. Using a global proteomics-based approach we have now been able to reveal the altered expression of a diverse range of hippocampal proteins following exposure to an enriched environment. Male Hooded Lister rats (8 weeks) were subjected to a 6-week regimen in which they were housed in either non-enriched (open field) or enriched conditions (toys, wheels etc.). Whole protein extracts from stratum pyramidale and stratum radiatum of area CA1 were then isolated and subjected to differential gel electrophoresis [McNair K, Davies CH, Cobb SR (2006) Plasticity-related regulation of the hippocampal proteome. Eur J Neurosci 23(2):575-580]. Of the 2469 resolvable protein spots detected in this study, 42 spots (1.7% of the detectable proteome) derived from predominantly somatic fractions and 32 proteins spots from dendritic fractions (1.3% of detectable proteome) were significantly altered in abundance following exposure to an enriched environment (somatic: 14 increased/28 decreased abundance, range -1.5 to +1.4-fold change; dendritic: 16 increased, 16 decreased abundance, range -1.6 to +3.0-fold change). Following in-gel tryptic digestion and Maldi-Tof/Q-star mass spectrometry, database searching revealed the identity of 50 protein spots displaying environmental enrichment-related modulation of expression. Identified proteins belonged to a variety of functional classes with gene ontology analysis revealing the majority (>70%) of regulated proteins to be part of the energy metabolism, cytoplasmic organization/biogenesis and signal transduction processes.

  5. How does a fish's metabolic rate influence its performance in a changing environment?

    Full Text Available Fish provide some of the best-studied examples of marked intraspecific variation in metabolic rate: after accounting for variation in size and age, there can typically be a 2-3 fold variation among individual fish for both standard and maximum metabolic rate (SMR and MMR, and also in their aerobic scope (AS, the difference between SMR and MMR and hence a fish’s capacity to increase its aerobic metabolism. These differences are relatively stable over time, although individual fish differ in the extent to which they can alter their metabolism when environmental conditions change. In this presentation I will briefly consider the extent and causes of individual variation in SMR, MMR and AS, considering both the mechanistic basis (e.g. individual variation in mitochondrial performance and its origins, including a consideration of genetic and maternal effects. I will then describe both documented and potential links between metabolism, behaviour and performance. Intraspecific variation in metabolism has been found to be related to other traits. As an example, fish with a relatively high SMR tend to be more dominant, digest food faster and grow faster than those with a low SMR, but these advantages only apply in environments where the food supply is high and predictable; in less favourable environments they lose their advantage, and are more prone to risk-taking when conditions deteriorate. Less is known about the ecological consequences of individual variation in MMR and AS, although fish with a higher AS are known to have advantages in some contexts. This is especially important in the context of climate change, since it has been suggested that constraints on AS may underlie the poor performance of fishes at higher temperatures. Given these links between metabolism and measures of performance, understanding the metabolic responses of individuals to changing environments will be a key area for future research.

    We argue that corporate boards are a dynamic repository of human- and social capital in response to external institutional evolution. Theoretically, integrating institutional economics, agency theory and resource dependence theory, we explain that evolution of market-, legal- and political....... Such particular contexts entail the external competitive environment and the principal-agency relationship in corporate governance, amplify (or weaken) the need for certain type of board roles, and ultimately require corporations to reconfigure the human- and social capital embedded within the board. Additionally......, since the board changes are typically proposed by the block shareholders, whose motivation for doing so is closely associated with a corporation’s financial performance, we further argue that financial performance is a key moderator of the relationships between institutional evolution and changes...

  9. Did the short PETM trigger long-lasting changes in terrestrial environments?

    Science.gov (United States)

    Fricke, H. C.; Clyde, W. C.

    2012-12-01

    The Paleocene Eocene Thermal Maximum (PETM) is a well-documented episode of warming where average temperatures increased 5-8 C in both marine and terrestrial settings before returning to pre-PETM values. As a result the PETM is generally thought of as a transient event that is superimposed on a longer-term trend of global change. Nevertheless not all aspects of the climatic-hydrologic-biologic system experienced a transient response to this event. For example, the well-known dispersal of mammals (Artiodactyls, Perrisopdactyls and Primates = APP taxa) at the beginning of the PETM resulted in fundamentally different terrestrial ecosystems dafter the PETM compared to before it. In this case the PETM can be considered not just a transient event, but a triggering, or threshold, event that resulted in long-term biotic change. Here we consider the possibility that the PETM acted as a threshold event for parts of the climatic and hydrologic system as well as the biologic system. A review of terrestrial/fluvial sections from Laramide basins of western North America (Bighorn, Green River, Huerfano/Raton, Piceance Creek, Powder River, San Juan, Tornillo, Uintah, Washakie, Williston, Wind River), reveals a pronounced difference between rocks of Paleocene and of Eocene age. Common differences include absence of lignites/coal beds in the Eocene, and the occurrence of highly oxidized paleosols and relatively fewer organic-rich mudstones compared to the Paleocene. These suggest drier conditions, either a decrease in mean annual precipitation or enhanced seasonal drying. In sections where the PETM can be identified on the basis of biostratigraphic indicators and carbon isotope excursions (Bighorn, Piceance Creek, Powder River and Williston Basins), and where the PETM can be inferred based on carbon isotope data alone (Huerfano/Raton?, Tornillo, Wind River Basins), it is associated with this transition from one long-lasting lithofacies (environment?) to another.

    Full Text Available This paper intends to make a reflection and analysis of the impact of theoretical and methodological frameworks of reference on different neo-institutional approaches in social policy. The paper questions the functionality and continuity of the institutions that are responsible for the functions of designing and implementing programs of social policy, given the profound changes on the environment of economic globalization processes. The method used primarily focuses on critical analysis and reflection. It is concluded that the institutions of welfare and social security must develop the technological, organizational and administrative skills to create and maintain institutional effects that go beyond being conductive to efficiency, effectiveness and equitable development.

    There was a very good observation area in Chongqing for the total solar eclipse along the Changjiang river on 22 July, 2009. Through the experiments, the outdoor meteorological data (solar radiation, air temperature and relative humidity) were observed and recorded on 21 July and 22 July. Based on the experimental observation data, the effect of thermal environment in Chongqing area was to analyzed and discussed. Experiment indicates that the reduction of air temperature and surface temperature resulted in the decrease in the solar radiation intensity, and the amplitude of the air temperature change is 2.4 degrees C during the total solar eclipse. Compared with the two days' air temperature, the amplitude of the air temperature change reached 4.6 degrees C on account of the total solar eclipse.

  12. Adapting to a Changing Environment: Modeling the Interaction of Directional Selection and Plasticity.

    Human-induced habitat loss and fragmentation constrains the range of many species, making them unable to respond to climate change by moving. For such species to avoid extinction, they must respond with some combination of phenotypic plasticity and genetic adaptation. Haldane's "cost of natural selection" limits the rate of adaptation, but, although modeling has shown that in very large populations long-term adaptation can be maintained at rates substantially faster than Haldane's suggested limit, maintaining large populations is often an impossibility, so phenotypic plasticity may be crucial in enhancing the long-term survival of small populations. The potential importance of plasticity is in "buying time" for populations subject to directional environmental change: if genotypes can encompass a greater environmental range, then populations can maintain high fitness for a longer period of time. Alternatively, plasticity could be detrimental by lessening the effectiveness of natural selection in promoting genetic adaptation. Here, I modeled a directionally changing environment in which a genotype's adaptive phenotypic plasticity is centered around the environment where its fitness is highest. Plasticity broadens environmental tolerance and, provided it is not too costly, is favored by natural selection. However, a paradoxical result of the individually advantageous spread of plasticity is that, unless the adaptive trait is determined by very few loci, the long-term extinction risk of a population increases. This effect reflects a conflict between the short-term individual benefit of plasticity and a long-term detriment to population persistence, adding to the multiple threats facing small populations under conditions of climate change.

    Full Text Available Due to a growing public awareness, in the last 40 years environmental impacts of development projects financed and supported by the World Bank and the International Monetary Fund (IMF have come into view. Since then, the member states have pressured both organizations to implement environmental concerns. We analyze the reactions of the World Bank and the IMF’s bureaucracies towards their principals’ demands. To reveal if, and to what extent, the observed reactions of both bureaucracies towards environmental integration can be assessed as organizational learning, we develop in a first step a heuristic model that allows for a distinction between different levels of learning (compliant and non-compliant, single-loop and double-loop. In a second step we describe the efforts of the bureaucracies of the World Bank (from the 1970s until today and the IMF (from the 1990s until today to integrate environmental protection into their activities. Due to our interest in the quality of the organizational changes, we finally analyze if and to what extent the bureaucracies’ reactions to the new external demand qualify as organizational learning. Furthermore, we discuss which factors helped or hindered organizational learning.

    The Institute of Medicine (IOM; 2010) has called for a transformation of the nursing profession to lead the redesign of health care in the United States. It acknowledges the need for profound change in nursing education, particularly advanced practice education, to produce the next generation of leaders in sufficient quantity to expand access, improve quality, and reduce cost. Although the IOM provides welcome validation of nursing's significant role, most of the recommendations are not new and have been advocated by nurse educators for decades. What has prevented us from creating the nimble and responsive educational programs that would ensure a sufficient corpus of advanced practice nurses with the relevant knowledge and skill to transform our ailing health system? Conceptualizing nursing as a complex, adaptive system (J.W. Begun and K. White, 1997), this article explores three examples of the dominant logic, grounded in a historical legacy that has kept the nursing profession from realizing its promise as a potent force: (a) the continuing preference for experience over education, (b) the belief that only nurses can teach nurses, and (c) the hegemony of the research doctorate.

    Average chain length (ACL) of leaf wax components preserved in lacustrine sediments and soil profiles has been widely adopted as a proxy indicator for past changes in vegetation, environment and climate during the late Quaternary. The fundamental assumption is that woody plants produce leaf waxes with shorter ACL values than non-woody plants. However, there is a lack of systematic survey of modern plants to justify the assumption. Here, we investigated various types of plants at two lakes, Blood Pond in the northeastern USA and Lake Ranwu on the southeastern Tibetan Plateau, and found that the ACL values were not significantly different between woody and non-woody plants. We also compiled the ACL values of modern plants in the literatures and performed a meta-analysis to determine whether a significant difference exists between woody and non-woody plants at single sites. The results showed that the ACL values of plants at 19 out of 26 sites did not show a significant difference between the two major types of plants. This suggests that extreme caution should be taken in using ACL as proxy for past changes in vegetation, environment and climate.

    Alpine areas often suffer significant loss and damage due to a range of natural processes such as landslides, debris flows, snow avalanches or floods. Sealing of the soil surface, settling in endangered areas and enhanced human intervention in the natural settings, as well as socio-economic changes, increase the risk and susceptibility of built environments to natural hazards and the costs of the consequences in a spatio-temporal context. The present study examines the loss estimation of a particular debris flow event for different points in time. The event occurred in August 1987, affected the municipality Martell in South Tyrol, Italy, and resulted in a total cost of € 25 million. The approach presented in this paper focuses on the changes of the land use and settlement expansion in the area since 1954 and attempts to assess the monetary impact of a similar event, which could have happened before (1954, 1985) or following the actual event (1992, 1999, 2006). The method applied is based on the use of a vulnerability curve which was developed for the specific area, based on the documentation of the damage of the 1987 event. Based on this curve, a loss estimation was carried out in order to visualise the risk evolution in a period of 52 yr (1954 to 2006). The results show a significant increase in the extent of the built environment (number, size and value of buildings) which consequently reflect an increase of the potential overall loss through the years. The method can be used in order to assess the potential loss for future scenarios based on different spatial patterns of the built environment.

    Full Text Available Urban flooding causes large economic losses, property damage and loss of lives. The impact of environmental changes, mainly urbanization and climatic change, leads to increased runoff and peak flows which the drainage system must be able to cope with to reduce potential damage and inconvenience. Allowing for detention storage to compliment the conveyance capacity of the drainage system network is one of the approaches to reduce urban floods. Contemporary practice is to design systems against stationary environmental forcings – including design rainfall, landuse, etc. Due to the rapid change in the climate- and the urban environment, this approach is no longer appropriate, and explicit consideration of gradual changes during the life-time of the drainage system is warranted. In this paper, a staged cost optimization tool based on the hydraulic performance of the drainage system is presented. A one dimensional hydraulic model is used for hydraulic evaluation of the network together with a genetic algorithm based optimization tool to determine optimal intervention timings and responses over the analysis period. The model was applied in a case study area in the city of Porto Alegre, Brazil. It was concluded that considerable financial savings and/or additional level of flood-safety can be achieved by approaching the design problem as a staged plan rather than one-off scheme.

    Many arctic mammals are adapted to live year-round in extreme environments with low winter temperatures and great seasonal variations in key variables (e.g. sunlight, food, temperature, moisture). The interaction between hosts and pathogens in high northern latitudes is not very well understood with respect to intra-annual cycles (seasons). The annual cycles of interacting pathogen and host biology is regulated in part by highly synchronized temperature and photoperiod changes during seasonal transitions (e.g., freezeup and breakup). With a warming climate, only one of these key biological cues will undergo drastic changes, while the other will remain fixed. This uncoupling can theoretically have drastic consequences on host-pathogen interactions. These poorly understood cues together with a changing climate by itself will challenge host populations that are adapted to pathogens under the historic and current climate regime. We will review adaptations of both host and pathogens to the extreme conditions at high latitudes and explore some potential consequences of rapid changes in the Arctic.

With a warming climate, only one of these key biological cues will undergo drastic changes, while the other will remain fixed. This uncoupling can theoretically have drastic consequences on host-pathogen interactions. These poorly understood cues together with a changing climate by itself will challenge host populations that are adapted to pathogens under the historic and current climate regime. We will review adaptations of both host and pathogens to the extreme conditions at high latitudes and explore some potential consequences of rapid changes in the Arctic.

    Many arctic mammals are adapted to live year-round in extreme environments with low winter temperatures and great seasonal variations in key variables (e.g. sunlight, food, temperature, moisture). The interaction between hosts and pathogens in high northern latitudes is not very well understood with respect to intra-annual cycles (seasons). The annual cycles of interacting pathogen and host biology is regulated in part by highly synchronized temperature and photoperiod changes during seasonal transitions (e.g., freezeup and breakup). With a warming climate, only one of these key biological cues will undergo drastic changes, while the other will remain fixed. This uncoupling can theoretically have drastic consequences on host-pathogen interactions. These poorly understood cues together with a changing climate by itself will challenge host populations that are adapted to pathogens under the historic and current climate regime. We will review adaptations of both host and pathogens to the extreme conditions at high latitudes and explore some potential consequences of rapid changes in the Arctic. PMID:21392401

    农村金融生态环境是新型农村金融机构生存和发展的环境基础.为了深入揭示农村金融生态环境对新型农村金融机构脆弱性的影响程度,在分析农村金融生态环境属性构成基础上,构建了农村金融生态环境与新型农村金融机构脆弱性的关系模型,并在问卷调查基础上运用结构方程模型进行实证检验,研究结果表明:除了农村法律环境的影响假设未得到支持外,农村经济环境、农村金融环境、农村政策环境和农村信用环境在降低新型农村金融机构脆弱性方面有显著正向影响.%Rural financial ecological environment provides the basis for the existence and development of new-type rural financial institutions. In order to reveal how much the rural financial ecological environment has influenced the fragility of new-type rural financial institutions this paper, based on an analysis of the components of rural financial ecological environment, constructs a relation model between the rural financial ecological environment and the new-type rural financial Institutions' fragility. SEM is used to analyze the questionnaires. The result proves that rural financial ecological environment consists of five parts: except rural legal environment, rural economic environment, rural financial environment, rural policy environment, rural legal environment and rural credit environment all have a significant positive effect on New-type rural financial Institutions' fragility.

    The objective of this abstract is to present the HOLOANTAR project, a multidisciplinary research funded by the Portuguese Government. The project integrates 16 researchers from different international institutions (Portugal, Spain, Brazil and Uruguay).. The main purpose of HOLOANTAR is to infer the palaeoenvironmental evolution and associated climate variability occurred over the last millennia in ice-free areas of the Maritime Antarctica based on the study of lake sediments. The South Shetland Islands (SSI) are located in the northwestern tip of the Antarctic Peninsula, one of the Earth's regions that have experienced a stronger warming signal during the second half of the 20th century. In the ice-free areas of this archipelago the terrestrial ecosystem is supported by permafrost, though its reaction to climate change is still poorly known. However, in the recent years a very important effort took place to monitor the thermal state and characteristics of permafrost in order to study its response to the recent warming trend. Many international teams are involved on several of these long-term monitoring projects, but HOLOANTAR, in addition, pretends to offer a new integrated approach aiming to bridge the gap between contemporary and past changes in permafrost environments. HOLOANTAR project is based on two main hypotheses: a) A multi-proxy analysis of lake sediments will allow reconstructing the palaeoecological evolution in the Maritime Antarctic and the role played in it by permafrost and active layer dynamics, b) The detection of activity rates, spatial patterns and geographical controls of contemporary key-geomorphic processes and permafrost distribution, will allow defining their limiting climatic conditions that will be used to interpret the sedimentary record. This approach is innovative since it will focus on both present and past geomorphodynamics as keys for understanding the landscape evolution.

    Dryland environments are estimated to cover around 40% of the global land surface (Okin et al, 2009) and are home to approximately 2.5 billion people (Reynolds et al. 2007). Many of these areas have recently experienced extensive land degradation. One such area and the focus of this project is the semi-arid US Southwest, where degradation over the past 150 years has been characterised by the invasion of woody vegetation into grasslands. Transition from grass to woody vegetation results in a change in ecosystem structure and function (Turnbull et al, 2008). Structural change is typically characterised by an increased heterogeneity of soil and vegetation resources, associated with reduced vegetation coverage and an increased vulnerability to soil erosion and the potential loss of key nutrients to adjacent fluvial systems. Such loss of resources may impact heavily upon the amount of carbon that is sequestered by these environments and the amount of carbon that is lost as the land becomes more degraded. Therefore, understanding these vegetation transitions is significant for sustainable land use and global biogeochemical cycling. This project uses an ecohydrological approach, monitoring natural rainfall-runoff events over six bounded plots with different vegetation coverage. The experiment takes advantage of a natural abundance stable 13C isotope shift from C3 piñon-juniper (Pinus edulis-Juniperus monosperma) mixed stand through a C4 pure-grass (Bouteloua eriopoda) to C3 shrub (Larrea tridentata). Data collected quantify fluvial fluxes of sediment and associated soil organic matter and carbon that is lost from across the grass-to-shrub and grass-to-woodland transition (where change in space is taken to indicate a similar change through time). Results collected during the 2010 and 2011 monsoon seasons will be presented, illustrating that soil and carbon losses are greater as the ecosystem becomes more dominated by woody plants. Additionally this project utilises novel

  11. Water scarcity and institutional change: lessons in adaptive governance from the drought experience of Perth, Western Australia.

    Urban water systems will be increasingly challenged under future climates and global pressures. Meeting challenges by reconfiguring water systems to integrate supplies and deliver multifunctional uses is technically well described. Adjusting the institutions that frame the management of these systems is not well operationalized in practice or conceptualized in theory. This study seeks to address this gap through an institutional analysis of Perth, Australia, a city where drought crisis has put under pressure both management practices and the institutional setting that underlies them. The study found that while trusted practices moderated water scarcity, the stability of the institutional setting may not facilitate a shift toward adaptable institutional configurations suited to future conditions. The results identified three key ingredients for a flexible institutional setting: (i) feedbacks in the system through better information management, (ii) reflexive dialogue and strategic use of projects to generate greater learning opportunities, and (iii) policy level support for sector-wide collaboration through progressive agendas, incentives for innovation and capacity building in stakeholder and community engagement. Further, the results suggest that a deeper understanding of institutional dynamics is needed to enable adaptive governance. The paper provides an analytical framework for diagnosing how greater adaptive capacity might be mobilized through influencing these dynamics.

    The prospect of sea level rise and increase in extreme weather conditions has led to a new focus on coastal defense in the Netherlands. As an innovative solution for coastal erosion a mega-nourishment named the Sand Motor (or Sand Engine) has been constructed at the Dutch coast. This body of sand will be distributed slowly along the coastline by wind, waves and currents; keeping the coastal defense structures in place and creating a unique, dynamic environment with changing morphology over time. The large size and position of the Sand Motor might lead to a substantial increase of fresh ground water resources. This creates an opportunity to combine coastal protection with an increase of fresh water resources in coastal regions. With a three dimensional, density dependent, groundwater model the effects of changing morphology over time and the potential increase in fresh water availability have been studied. The preliminary model calculations show that in a period of 20 years volume of fresh water gradually increases to ca. 12 Mm3. In the nearby dune area 7-8 Mm3 is abstracted yearly, therefore the first results are promising in increasing fresh groundwater resources. More model calculations will be performed to investigate the sensitivity of the change in the fresh, brackish and salt water distribution.

    Offers a regionally focussed approach. Describes research on adaptive evolution. State-of-the-art content. The second volume of ''Adaptation and Evolution in Marine Environments - The Impacts of Global Change on Biodiversity'' from the series ''From Pole to Pole'' integrates the marine biology contribution of the first tome to the IPY 2007-2009, presenting overviews of organisms (from bacteria and ciliates to higher vertebrates) thriving on polar continental shelves, slopes and deep sea. The speed and extent of warming in the Arctic and in regions of Antarctica (the Peninsula, at the present) are greater than elsewhere. Changes impact several parameters, in particular the extent of sea ice; organisms, ecosystems and communities that became finely adapted to increasing cold in the course of millions of years are now becoming vulnerable, and biodiversity is threatened. Investigating evolutionary adaptations helps to foresee the impact of changes in temperate areas, highlighting the invaluable contribution of polar marine research to present and future outcomes of the IPY in the Earth system scenario.

  16. Using Nematostella vectensis to study the interactions between genome, epigenome and bacteria in a changing environment

    Full Text Available The phenotype of an animal cannot be explained entirely by its genes. It is now clear that factors other than the genome contribute to the ecology and evolution of animals. Two fundamentally important factors are the associated microbiota and epigenetic regulations. Unlike the genes and regulatory regions of the genome, epigenetics and microbial composition can be rapidly modified, and may thus represent mechanisms for rapid acclimation to a changing environment. At present, the individual functions of epigenetics, microbiomes, and genomic mutations are largely studied in isolation, particularly for species in marine ecosystems. This single variable approach leaves significant questions open for how these mechanisms intersect in the acclimation and adaptation of organisms in different environments. Here, we propose that the starlet sea anemone, Nematostella vectensis, is a model of choice to investigate the complex interplay between adaptation as well as physiological and molecular plasticity in coastal ecosystems. N. vectensis’ geographic range spans four distinct coastlines, including a wide thermocline along the Atlantic coast of North America. N. vectensis is a particularly powerful invertebrate model for studying genome-environment interactions due to (1 the availability of a well-annotated genome, including preexisting data on genome methylation, histone modifications and miRNAs, (2 an extensive molecular toolkit including well-developed protocols for gene suppression and transgenesis, and (3 the simplicity of culture and experimentation in the laboratory. Taken together, N. vectensis has the tractability to connect the functional relationships between a host animal, microbes, and genome modifications to determine mechanisms underlying phenotypic plasticity and local adaptation.

    Species management has been utilized by the zoo and aquarium industry, since the mid-1990s, to ensure the ongoing genetic and demographic viability of populations, which can be difficult to maintain in the ever-changing operating environments of zoos. In 2009, the Zoo and Aquarium Association Australasia reviewed their species management services, focusing on addressing issues that had arisen as a result of the managed programs maturing and operating environments evolving. In summary, the project examined resourcing, policies, processes, and species to be managed. As a result, a benchmarking tool was developed (Health Check Report, HCR), which evaluated the programs against a set of broad criteria. A comparison of managed programs (n = 98), between 2008 and 2011, was undertaken to ascertain the tool's effectiveness. There was a marked decrease in programs that were designated as weak (37 down to 13); and an increase in excellent programs (24 up to 49) between the 2 years. Further, there were significant improvements in the administration benchmarking area (submission of reports, captive management plan development) across a number of taxon advisory groups. This HCR comparison showed that a benchmarking tool enables a program's performance to be quickly assessed and any remedial measures applied. The increases observed in program health were mainly due to increased management goals being attained. The HCR will be an ongoing program, as the management of the programs increases and goals are achieved, criteria will be refined to better highlight ongoing issues and ways in which these can be resolved.

  19. Emergent adaptive behaviour of GRN-controlled simulated robots in a changing environment

    Full Text Available We developed a bio-inspired robot controller combining an artificial genome with an agent-based control system. The genome encodes a gene regulatory network (GRN that is switched on by environmental cues and, following the rules of transcriptional regulation, provides output signals to actuators. Whereas the genome represents the full encoding of the transcriptional network, the agent-based system mimics the active regulatory network and signal transduction system also present in naturally occurring biological systems. Using such a design that separates the static from the conditionally active part of the gene regulatory network contributes to a better general adaptive behaviour. Here, we have explored the potential of our platform with respect to the evolution of adaptive behaviour, such as preying when food becomes scarce, in a complex and changing environment and show through simulations of swarm robots in an A-life environment that evolution of collective behaviour likely can be attributed to bio-inspired evolutionary processes acting at different levels, from the gene and the genome to the individual robot and robot population.

    There are a lot of research themes in the field of urban planning and related fields as mitigation of global environment change. Main theme is reduction method of CO{sub 2} gas emission as a countermeasure against global warming. Some groups research on estimation of CO{sub 2} emission caused by construction activities both in building engineering and civil engineering and also on evaluation of countermeasures. They investigate reduction of CO{sub 2} emission by fossil fuel combustion and by building materials (cement, steel and so on) production process. But we cannot use data fitted to a spatial scale of urban planning. Many researches are focused on nation wide analysis. We, BRI, make a study of {open_quotes}Research on CO{sub 2} Emission in Urban Development and the Control Technologies{close_quotes} as will be seen later at 2. (2). There are two ways of research to reduce CO{sub 2} emission caused by daily activities to urban planning field. One is research on positive utilizing of natural environment in urban areas without depending to energy consuming artificial facilities. There is a research on mitigation of heat island phenomenon for instance. The other ways are research on improvement of energy consumption effect and on reusing of wasted energy In energy consuming type urban space for instance. There s a research on promoting District Heating and Cooling (DHC) and cogeneration.
