The result of the research shows that there is a social change in Bajo society living permanently in Karimunjawa that is, the change of daily behavior in the society, social interaction with other tribes, values held by the society and social institution, structure and social classes. Social change occurring to Bajo society in Karimunjawa brings positive influences. The social changes among others are awareness towards the importance of education, Bajo society has new jobs other than fisherman, the increase of income, living standard, also modernization in fisheries system. The negative impact as a consequence of the social changes is faded culture, changes in life orientation and views of life, and consumerism in the society.

Social psychiatry in a rapidly changing world

Directory of Open Access Journals (Sweden)

Thomas K. J. Craig

2016-01-01

Full Text Available Many societies around the world are experiencing a period of unprecedented change in traditional social roles and customs. Globalisation has contributed to materialism and a me-first individualism that heightens awareness of income inequality that itself is one of the most robust markers of unhappiness in society. Ever increasing urbanisation has driven an erosion of large ‘joint’ family arrangements to be replaced by smaller and relatively isolated nuclear families and single parent living. Mass migration has unmasked deep seated fear and prejudice towards the outsider in society. These global changes are fertile ground for the social conditions that have long been known to be risks for mental illness – poverty, poor quality child care, social isolation and the active discrimination and exclusion of the alien, the physically disabled and mentally ill. While there is little we can do to reverse global change, there is much a social psychiatrist can do to mitigate the effect, ensuring his/her voice is added to other calls for reducing discriminatory practice, promoting evidence-based social interventions such as parenting advice and peer support and ensuring that the success of a treatment is measured not just in terms of symptomatic improvement but in whether it results in an outcome that is valued by the patient.

Changing of the social structure and lifelong education –\tFrom the industrial society to the knowledge society

Directory of Open Access Journals (Sweden)

Ana Krajnc

2010-07-01

Full Text Available Social structures are changing. The industrial society is a hierarchical pyramid with separate social classes and the law of limited social mobility. The social status tended to be stable and was transmitted from parents to children. The information society, the knowledge society, the society in change and the risk society, is a turmoil of centripetal and centrifugal social forces. The social status of each individual, ranging from the highest ­ with their place in the very heart of the society­ to the lowest, is temporary. The main production resource in the accelerated economy of the information society is knowledge. Renewing competences is essential in order to preserve one’s social status in the social spiral; lagging behind in knowledge and in personal growth , on the other hand, shoves one off to the margins of society. The way back up to a more prestigious position can be achieved through education. Education systems differ from state to state. Some are losing their legitimacy since they fail to train young people for new methods of work and survival; they are an obstacle to the development of the most immanent properties in the new society, as e.g., innovativeness, independence, decision­making ability, creativity. If young people drop out from school too early, before they complete a four­year secondary school, they are surrendered to the street and crime. Manual workers are being discarded on a large scale to find themselves on the margins of society, among the "service proletariat" depending on the handouts of the welfare state. Whereas the GNP is increasing, the wealth redistribution stick to the old formulas and are widening the gap between the poor and the rich. The information society is opening up countless new opportunities, but it is also bringing new responsibilities. Work is becoming more humane, with the "brain" winning over "brawn".

Crowding-in: how Indian civil society organizations began mobilizing around climate change.

Science.gov (United States)

Ylä-Anttila, Tuomas; Swarnakar, Pradip

2017-06-01

This paper argues that periodic waves of crowding-in to 'hot' issue fields are a recurring feature of how globally networked civil society organizations operate, especially in countries of the Global South. We elaborate on this argument through a study of Indian civil society mobilization around climate change. Five key mechanisms contribute to crowding-in processes: (1) the expansion of discursive opportunities; (2) the event effects of global climate change conferences; (3) the network effects created by expanding global civil society networks; (4) the adoption and innovation of action repertoires; and (5) global pressure effects creating new opportunities for civil society. Our findings contribute to the world society literature, with an account of the social mechanisms through which global institutions and political events affect national civil societies, and to the social movements literature by showing that developments in world society are essential contributors to national mobilization processes. © London School of Economics and Political Science 2017.

Long-term dynamics emerging in floodplains and deltas from the interactions between hydrology and society in a changing climate

Di Baldassarre, Giuliano; Viglione, Alberto; Yan, Kun; Brandimarte, Luigia; Blöschl, Günter

2014-05-01

Economic losses and fatalities associated to flood events have increased dramatically over the past decades. This situation might worsen in the near future because of rapid urbanization of many floodplains and deltas, along with enhancement of flood water levels as a result of human interventions, climate variability or sea level rise. To explore future dynamics, we developed a novel approach, which takes into account the dynamic nature of flood risk by an explicit treatment of the interactions and feedbacks between the hydrological and social components of flood risk (i.e. probability of flooding, and potential adverse consequences). In particular, we developed a socio-hydrological model that allows considering how the frequency and magnitude of flooding shapes the evolution of societies, while, at the same time, dynamic societies shape the frequency and magnitude of flooding. We then use this model to simulate long-term dynamics of different types of societies under hydrological change, e.g. increasing flood frequency. Based on the study of long-term dynamics of different floodplains and deltas around the world (e.g. Netherlands, Bangladesh), we identify two main typologies of flood-shaped societies: i) techno-societies, which "fight floods", and typically deal with risk by building and strengthening flood protection structures, such as levees or dikes; and ii) green-societies, which "lives with floods", and mainly cope with risk via adaptation measures, such as resettling out of flood prone areas. The outcomes of this study are relevant for the management of deltas and floodplains as they allow a comparison of long-term dynamics between diverse types of societies in terms of robustness to hydrological change.

[Doctor-patient relationship in the context of a changing society].

Science.gov (United States)

Siebzehner, Miriam Ines; Balik, Chaya; Matalon, Andre

2008-12-01

During the 20th century doctors gained a special status in the medical system, which is about to change as a consequence of a change in the doctor-patient relationship and in the characteristics of the labor market in health care. Some changes correspond with the adoption of business terms within the medical system. The doctor is represented as a supplier of services, while the patient is a consumer. From patient-centered care, the doctor-patient relationship changed to a costumer-supplier of services, as is the case in other fields of the consumer society. This article analyzes the changes in the patterns of the doctor-patient interactions in the light of the changes in society over the last decades such as: the creation of regulations and laws on patients' rights; the establishment of organizations that represent the sick, the distribution of knowledge and information by means of mass communication, changes in the status of the doctors, the academization of other health professionals and changes in the management of health care to a more financially viable approach to the costs of health.

A shifting mosaic of scholarly publishing, scientific delivery, and future impact changing the face of learned societies

Science.gov (United States)

Leslie, David M.

2007-01-01

Nonprofit scientific societies hope that their activities advance their particular mission and impact their profession and, in the broadest sense, humanity in positive ways. The digital age has provided unprecedented mechanisms to enhance the delivery of science to the world. The marketplace of scientific publishing is a rapidly shifting mosaic of challenges and opportunities, and the responses of nonprofit and commercial publishers vary widely, but their outcomes are still uncertain. The response of the American Society of Mammalogists (ASM) provides an example of how a relatively small society has altered its scientific delivery to enhance member benefits while attempting to sustain its economic viability. Since 2000, ASM has moved from a self-publishing, break-even, print-only model to a copublishing agreement with a commercial publisher (Alliance Communications Group, a division of Allen Press, Inc., Lawrence, Kansas), which now offers members various print and electronic options and generates a shared royalty. Although it is too early to gauge the economic impact of these changes, the ASM leadership clearly attempted to signal its desire for members to view their society as a package of opportunities for edification and involvement rather than just a provider of serial subscriptions. Future challenges facing nonprofit scientific societies include open access, fiscal realities, archiving of publications, and scientific and societal impact; future opportunities include a strengthening of member responsibilities and professionalism, development of data registries to enhance scientific progress, and bundling of like societies. The manner in which nonprofit scientific societies respond to these challenges and opportunities will no doubt affect their sustainability and future impact. ?? 2007 American Society of Mammalogists.

The Arctic region will warm more rapidly than the global mean, influencing dramatically the northern ecosystems. Simultaneously, our societies transform towards urbanized, highly educated, service-based culture, where a decreasing population will gain its livelihood from primary production. We study various ecosystem interactions in a changing climate and integrate these with reindeer husbandry and the indigenous Sámi culture dependent on it1. Potential climate impacts include the transformation of arctic-alpine tundra to dense scrubland with conceivable consequences to reindeer husbandry, but also global warming due to decreasing albedo. The social-ecological system (SES) of reindeer husbandry includes administrative and ecological processes that do not always correspond (Figure 1). Consequently, management priorities and administration may conflict with local social and ecological processes, bringing about risks of environmental degradation, loss of biodiversity and defeat of traditional livelihoods. We hypothesize the plausibility to support the indigenous reindeer herding livelihood against rapid external changes by utilizing the migratory reindeer grazing system of the Sámi as a management tool for sustaining the high-albedo tundra and mitigating global warming. Our first-of-a-kind satellite-based high resolution vegetation map covering Northern Fennoscandia allows detailed management plans. Our ecological research demonstrates the important role of herbivory on arctic vegetation communities. Interactive workshops with reindeer herders offer indigenous knowledge of state and changes of the ecosystems, and reflect the threats and expectations of the herders. We are currently building models of the complex social-ecological system of Northern Fennoscandia and will report the first findings of the exercise. 1 www.ncoetundra.utu.fi Figure 1.

The summer of 2001 saw the inauguration of the Global Climate Change and Society Program (GCCS), an eight week, NSF-funded experiment in undergraduate pedagogy held at the University of Colorado and the National Center for Atmospheric Research. Acknowledging from the start that climate change is more than a scientific problem, GCCS began with the simultaneous study of basic atmospheric physics, classical and environmental philosophy, and public policy. In addition to lectures and discussions on these subjects, our twelve undergraduates (majoring in the physical sciences, social sciences, and humanities) also participated in internships with scholars and researchers at NCAR, University of Colorado's Center of the American West, and the Colorado School of Mines, on specific issues in atmospheric science, science policy, and ethics and values. This talk will discuss the outcomes of GCCS: specifically, new insights into interdisciplinary pedagogy and the student creation of an extraordinary "deliverable," a group summary assessment of the global climate change debate. The student assessment called for an integrated discussion of both the science of climate change and the human values related to how we inhabit the world. The problems facing society today cannot be addressed through the single-minded adherence to science and technology; instead, society must develop new means of integrating the humanities and science in a meaningful dialogue about our common future.

Method for producing rapid pH changes

Science.gov (United States)

Clark, J.H.; Campillo, A.J.; Shapiro, S.L.; Winn, K.R.

A method of initiating a rapid pH change in a solution comprises irradiating the solution with an intense flux of electromagnetic radiation of a frequency which produces a substantial pK change to a compound in solution. To optimize the resulting pH change, the compound being irradiated in solution should have an excited state lifetime substantially longer than the time required to establish an excited state acid-base equilibrium in the solution. Desired pH changes can be accomplished in nanoseconds or less by means of picosecond pulses of laser radiation.

Increasing attention to patient safety in training hospitals may come at the expense of trainee autonomy and professional growth. This study sought to examine changes in medical trainees' self-reported behaviour after the institution-wide implementation of a rapid response system. We conducted a two-point cross-sectional survey of medical trainees in 2006, during the implementation of a rapid response system, and in 2010, in a single academic medical centre. A novel instrument was used to measure trainee likelihood of calling for supervisory assistance, perception of autonomy, and comfort in managing decompensating patients. Non-parametric tests to assess for change were used and year of training was evaluated as an effect modifier. Response rates were 38% in 2006 and 70% in 2010. After 5 years of the full implementation of the rapid response system, residents were significantly more likely to report calling their attending physicians for assistance (rising from 40% to 65% of relevant situations; p autonomy at 5 years after the implementation of the rapid response system. These changes were mirrored in the actual use of the rapid response system, which increased by 41% during the 5-year period after adjustment for patient volume (p < 0.0001). A primary team-focused implementation of a rapid response system was associated with durable changes in resident physicians' reported behaviour, including increased comfort with involving more experienced physicians and managing unstable patients. © 2014 John Wiley & Sons Ltd.

Women in Physics in a Rapidly Changing China

Wu, Ling-An

2008-03-01

Despite the upheavals of the 20th century, physics managed to survive quite well in China, where the first woman president of the American Physical Society was born and bred. During the 1950s as a result of policies that emphasized science and engineering, declared equal rights and equal pay for men and women, and assigned jobs to college graduates irrespective of sex, the number of women in physics increased rapidly, many of whom made notable achievements. Since China's opening up over the last thirty years tremendous changes have taken place, and women now face new opportunities as well as challenges in all aspects of society. Whereas physics used to be regarded as the most elite of the sciences, new fields such as computer science, biotechnology and business are now competing for the best students. Compared with other countries the statistics are not bad; in schools and many physics departments the ratio of women teachers may be 30% or higher, but the numbers drop drastically with rank. Moreover, in some research institutions the ratio of female physicists is actually declining, due to retirement of the older generation and fewer successors. Compulsory retirement for women at an earlier age than for men is also a new factor. Conversely, in recent years the ratio of female graduate students enrolling in physics has increased, even reaching 40% in some universities. However, the reasons for this do not bode well: men are not performing so well as women in entrance exams, while the latter are facing increasing discrimination in employment so they have to seek higher degree qualifications. With the further development of China's economy there will be abundant demand for qualified personnel including women with a physics background. It is imperative to actively support the upcoming generation of women physicists and not lose them in the leaky pipeline. The Chinese Physical Society has taken certain positive steps, such as the recent establishment of the Xie Xi

Rapid changes in genetic architecture of behavioural syndromes following colonization of a novel environment.

2016-01-01

Behavioural syndromes, that is correlated behaviours, may be a result from adaptive correlational selection, but in a new environmental setting, the trait correlation might act as an evolutionary constraint. However, knowledge about the quantitative genetic basis of behavioural syndromes, and the stability and evolvability of genetic correlations under different ecological conditions, is limited. We investigated the quantitative genetic basis of correlated behaviours in the freshwater isopod Asellus aquaticus. In some Swedish lakes, A. aquaticus has recently colonized a novel habitat and diverged into two ecotypes, presumably due to habitat-specific selection from predation. Using a common garden approach and animal model analyses, we estimated quantitative genetic parameters for behavioural traits and compared the genetic architecture between the ecotypes. We report that the genetic covariance structure of the behavioural traits has been altered in the novel ecotype, demonstrating divergence in behavioural correlations. Thus, our study confirms that genetic correlations behind behaviours can change rapidly in response to novel selective environments. © 2015 European Society For Evolutionary Biology.

The predicted climate warming has raised many questions and concerns about its impacts on the environment and society. As a respond to the need of holistic studies comprising both of these areas, The Academy of Finland launched The Finnish Research Programme on Climate Change (FICCA 2011-2014) in spring 2010 with the main aim to focus on the interaction between the environment and society. Ultimately 11 national consortium projects were funded (total budget 12 million EUR). Here we shortly present the main objectives of the largest consortium project "Climate change on arctic environment, ecosystem services and society" (CLICHE). The CLICHE consortium comprises eight interrelated work packages (treeline, diversity, peatlands, snow, lakes, fish, tourism, and traditional livelihoods), each led by a prominent research group and a team leader. The research consortium has three main overall objectives: 1) Investigate, map and model the past, present and future climate change-induced changes in central ecosystems of the European Arctic with unprecedented precision 2) Deepen our understanding of the basic principles of ecosystem and social resilience and dynamics; identify key taxa, structures or processes that clearly indicate impending or realised global change through their loss, occurrence or behaviour, using analogues from the past (e.g. Holocene Thermal Maximum, Medieval Warm Period), experiments, observations and models 3) Develop adaptation and mitigation strategies to minimize the adverse effects of climate change on local communities, traditional livelihoods, fisheries, and tourism industry, and promote sustainable development of local community structures and enhance the quality of life of local human populations. As the project has started only recently no final results are available yet. However, the fieldwork as well as the co-operation between the research teams has thus far been very successful. Thus, the expectations for the final outcome of the project

The present volume contains the speeches and discussion reports of the 29th Trier colloquium on the environmental and techniques law, which was dedicated to the theme ''Energy change in the industrial society''. The goal a the colloquium consisted, to work out central questions of the energy change and also to look beyond the legal field. The documented speeches deal mainly with the promotional system of the renewal-energy law and its need for reform, whereby this topic is discussed from legal, economic, and business perspective. A further main topic form questions of planning. Hereby it deals both with the regulation of the increased use of renewable energies in zoning and land-use planning and with the network expansion including public participation. Object of the discussion are also the providing of the base load by conventional power plants as well as legal questions of the compensation and load balancing in the connection of off-shore facilities.

Changing Landscapes in Documentation Efforts: Civil Society Documentation of Serious Human Rights Violations

Directory of Open Access Journals (Sweden)

Brianne McGonigle Leyh

2017-04-01

Full Text Available Wittingly or unwittingly, civil society actors have long been faced with the task of documenting serious human rights violations. Thirty years ago, such efforts were largely organised by grassroots movements, often with little support or funding from international actors. Sharing information and best practices was difficult. Today that situation has significantly changed. The purpose of this article is to explore the changing landscape of civil society documentation of serious human rights violations, and what that means for standardising and professionalising documentation efforts. Using the recent Hisséne Habré case as an example, this article begins by looking at how civil society documentation can successfully influence an accountability process. Next, the article touches upon barriers that continue to impede greater documentation efforts. The article examines the changing landscape of documentation, focusing on technological changes and the rise of citizen journalism and unofficial investigations, using Syria as an example, as well as on the increasing support for documentation efforts both in Syria and worldwide. The changing landscape has resulted in the proliferation of international documentation initiatives aimed at providing local civil society actors guidelines and practical assistance on how to recognise, collect, manage, store and use information about serious human rights violations, as well as on how to minimise the risks associated with the documentation of human rights violations. The recent initiatives undertaken by international civil society, including those by the Public International Law & Policy Group, play an important role in helping to standardise and professionalise documentation work and promote the foundational principles of documentation, namely the ‘do no harm’ principle, and the principles of informed consent and confidentiality. Recognising the drawback that greater professionalisation may bring, it

2017-04-01

The rapid aminoglycoside NP (Nordmann/Poirel) test was developed to rapidly identify multiple aminoglycoside (AG) resistance in Enterobacteriaceae It is based on the detection of the glucose metabolism related to enterobacterial growth in the presence of a defined concentration of amikacin plus gentamicin. Formation of acid metabolites was evidenced by a color change (orange to yellow) of the red phenol pH indicator. The rapid aminoglycoside NP test was evaluated by using bacterial colonies of 18 AG-resistant isolates producing 16S rRNA methylases, 20 AG-resistant isolates expressing AG-modifying enzymes (acetyl-, adenyl-, and phosphotransferases), and 10 isolates susceptible to AG. Its sensitivity and specificity were 100% and 97%, respectively, compared to the broth dilution method, which was taken as the gold standard for determining aminoglycoside resistance. The test is inexpensive, rapid (<2 h), and implementable worldwide. Copyright © 2017 American Society for Microbiology.

INTRODUCTION: Obesity is associated with increased all-cause mortality, but weight loss may not decrease cardiovascular events. In fact, very low calorie diets have been linked to arrhythmias and sudden death. The QT interval is the standard marker for cardiac repolarization, but T-wave morphology...... analysis has been suggested as a more sensitive method to identify changes in cardiac repolarization. We examined the effect of a major and rapid weight loss on T-wave morphology. METHODS AND RESULTS: Twenty-six individuals had electrocardiograms (ECG) taken before and after eight weeks of weight loss......A1c (pweight loss induces changes in cardiac repolarization. Monitoring of MCS during calorie restriction makes it possible to detect repolarization changes with higher discriminative power than the QT-interval during major rapid weight...

The Rapid Ice Sheet Change Observatory (RISCO)

Morin, P.; Howat, I. M.; Ahn, Y.; Porter, C.; McFadden, E. M.

2010-12-01

The recent expansion of observational capacity from space has revealed dramatic, rapid changes in the Earth’s ice cover. These discoveries have fundamentally altered how scientists view ice-sheet change. Instead of just slow changes in snow accumulation and melting over centuries or millennia, important changes can occur in sudden events lasting only months, weeks, or even a single day. Our understanding of these short time- and space-scale processes, which hold important implications for future global sea level rise, has been impeded by the low temporal and spatial resolution, delayed sensor tasking, incomplete coverage, inaccessibility and/or high cost of data available to investigators. New cross-agency partnerships and data access policies provide the opportunity to dramatically improve the resolution of ice sheet observations by an order of magnitude, from timescales of months and distances of 10’s of meters, to days and meters or less. Advances in image processing technology also enable application of currently under-utilized datasets. The infrastructure for systematically gathering, processing, analyzing and distributing these data does not currently exist. Here we present the development of a multi-institutional, multi-platform observatory for rapid ice change with the ultimate objective of helping to elucidate the relevant timescales and processes of ice sheet dynamics and response to climate change. The Rapid Ice Sheet Observatory (RISCO) gathers observations of short time- and space-scale Cryosphere events and makes them easily accessible to investigators, media and general public. As opposed to existing data centers, which are structured to archive and distribute diverse types of raw data to end users with the specialized software and skills to analyze them, RISCO focuses on three types of geo-referenced raster (image) data products in a format immediately viewable with commonly available software. These three products are (1) sequences of images

Prevention and Control of Cardiovascular Disease in the Rapidly Changing Economy of China.

2016-06-14

With one-fifth of the world's total population, China's prevention and control of cardiovascular disease (CVD) may affect the success of worldwide efforts to achieve sustainable CVD reduction. Understanding China's current cardiovascular epidemic requires awareness of the economic development in the past decades. The rapid economic transformations (industrialization, marketization, urbanization, globalization, and informationalization) contributed to the aging demography, unhealthy lifestyles, and environmental changes. The latter have predisposed to increasing cardiovascular risk factors and the CVD pandemic. Rising CVD rates have had a major economic impact, which has challenged the healthcare system and the whole society. With recognition of the importance of health, initial political steps and national actions have been taken to address the CVD epidemic. Looking to the future, we recommend that 4 priorities should be taken: pursue multisectorial government and nongovernment strategies targeting the underlying causes of CVD (the whole-of-government and whole-of-society policy); give priority to prevention; reform the healthcare system to fit the nature of noncommunicable diseases; and conduct research for evidence-based, low-cost, simple, sustainable, and scalable interventions. By pursuing the 4 priorities, the pandemic of CVD and other major noncommunicable diseases in China will be reversed and the global sustainable development goal achieved. © 2016 American Heart Association, Inc.

Trusted Sources: The Role Scientific Societies Can Play in Improving Public Opinions on Climate Change

Science.gov (United States)

McEntee, C.; Cairns, A.; Buhrman, J.

2012-12-01

Public acceptance of the scientific consensus regarding climate change has eroded and misinformation designed to confuse the public is rapidly proliferating. Those issues, combined with an increase of politically motivated attacks on climate scientists and their research, have led to a place where ideology can trump scientific consensus as the foundation for developing policy solutions. The scientific community has been, thus far, unprepared to respond effectively to these developments. However, as a scientific society whose members engage in climate science research, and one whose organizational mission and vision are centered on the concepts of science for the benefit of humanity and ensuring a sustainable future, the American Geophysical Union can, and should, play an important role in reversing this trend. To that end, in 2011, AGU convened a Leadership Summit on Climate Science Communication, in which presidents, executive directors, and senior public policy staff from 17 scientific organizations engaged with experts in the social sciences regarding effective communication of climate science and with practitioners from agriculture, energy, and the military. The discussions focused on three key issues: the environment of climate science communication; public understanding of climate change; and the perspectives of consumers of climate science-based information who work with specific audiences. Participants diagnosed previous challenges and failings, enumerated the key constituencies that need to be effectively engaged, and identified the critical role played by cultural cognition—the influence of group values, particularly around equality and authority, individualism, and community; and the perceptions of risk. Since that meeting, AGU has consistently worked to identify and explore ways that it, and its members, and improve the effectiveness of their communication with the public about climate change. This presentation will focus on the insights AGU has

Two key concepts of the society-climate change interface: vulnerability and adaptation

International Nuclear Information System (INIS)

Magnan, Alexandre

2010-06-01

Vulnerability and adaptation are two inseparable concepts, each being dependent on the other. Although they are extremely sensitive to the contextual specificities of particular areas, vulnerability reduction and adaptation strategies can only be developed at the interface between different spatial and temporal scales. This leads us to assert that faced with a common threat - climate change -, different types of vulnerability and adaptation exist. The aim of this text is to provide an overview of two concepts that can no longer be ignored in discussions on climate change: vulnerability and adaptation. These are two pillars for analysing both the potential impact of climate change on societies and regions, and also their ability to live with these consequences. We will begin by describing how the interdependence of these two concepts explains the position(s) of present and future societies in the face of climate change impacts. We will then show that they share certain determinants that may themselves provide an appropriate framework for analysis. Finally, we will insist on the fact that these two concepts nevertheless remain extremely difficult to grasp, as they require a multi-scalar and multi-temporal approach to regions, which also explains why they are a relevant response to the challenges posed by climate change. The conclusion will call for wider discussion, reiterating that since their nature is fundamentally linked to the diversity and specificities of regions and societies, we must accept the idea that faced with the same threat - climate change - there are different types of vulnerability and adaptation.

Abrupt climate change in the past is thought to have disrupted societies by accelerating environmental degradation, potentially leading to cultural collapse. Linking climate change directly to societal disruption is challenging because socioeconomic factors also play a large role, with climate being secondary or sometimes inconsequential. Combining paleolimnologic, historical, and archaeological methods provides for a more secure basis for interpreting the past impacts of climate on society. We present pollen, non-pollen palynomorph, geochemical, paleomagnetic and sedimentary data from a high-resolution 2700 yr lake sediment core from central Italy and compare these data with local historical documents and archeological surveys to reconstruct a record of environmental change in relation to socioeconomic history and climatic fluctuations. Here we document cases in which environmental change is strongly linked to changes in local land management practices in the absence of clear climatic change, as well as examples when climate change appears to have been a strong catalyst that resulted in significant environmental change that impacted local communities. During the Imperial Roman period, despite a long period of stable, mild climate, and a large urban population in nearby Rome, our site shows only limited evidence for environmental degradation. Warm and mild climate during the Medieval Warm period, on the other hand, led to widespread deforestation and erosion. The ability of the Romans to utilize imported resources through an extensive trade network may have allowed for preservation of the environment near the Roman capital, whereas during medieval time, the need to rely on local resources led to environmental degradation. Cool wet climate during the Little Ice Age led to a breakdown in local land use practices, widespread land abandonment and rapid reforestation. Our results present a high-resolution regional case study that explores the effect of climate change on

According to demographic changes, the size of the aging population has rapidly increased. Thailand has been facing the "aging society" since 2005 and the "aged society" has been projected to appear by the year 2025. Increased life expectancy is associated with health problems and risks, specifically chronic diseases and disability. Aging and aged societies and related specific conditions as stroke require the provision of services from health professionals. The shortage of the physical therapy workforce in Thailand has been reported. This study investigated the size of physical therapy workforce required for the approaching aging society of Thailand and estimated the number of needed physical therapists, specifically regarding stroke condition. Evidently, the issue of the physical therapy workforce to serve aging and aged societies in Thailand requires advocating and careful arranging.

Hof, Christian; Levinsky, Irina; Bastos Araujo, Miguel

2011-01-01

Ongoing climate change is assumed to be exceptional because of its unprecedented velocity. However, new geophysical research suggests that dramatic climatic changes during the Late Pleistocene occurred extremely rapid, over just a few years. These abrupt climatic changes may have been even faster...... than contemporary ones, but relatively few continent-wide extinctions of species have been documented for these periods. This raises questions about the ability of extant species to adapt to ongoing climate change. We propose that the advances in geophysical research challenge current views about...... species' ability to cope with climate change, and that lessons must be learned for modelling future impacts of climate change on species....

On being a scientist in a rapidly changing world.

Science.gov (United States)

Mandel, I D

1996-02-01

The practice of biological science has changed dramatically since mid-century, reshaped not only by a rapid series of landmark discoveries, but also by governmental directives, institutional policies, and public attitudes. Until 1964, the major influences were the mentor, who provided direction and indoctrination into the culture of science, and in dentistry, the newly established NIDR, which fueled the research engine with an expanding research and training program. The 1965-74 period witnessed the advent of the Institutional Review Board, an increased social involvement of biological scientists, and a recognition of the need for biological and physical safeguards in the conduct of research. The most turbulent years were 1975-89, when there was a confluence of animal rights activism and regulation, growing concerns with scientific fraud and publication malpractice, and the stresses and strains (and opportunities) resulting from the rapid expansion of the academic-industrial complex. The current period is characterized by rapid pace, high volume, and an increased depth and breadth of knowledge-a major change in scale in the conduct of science. It is an exciting time but one in which ethical issues are multiplying. Attention must be paid.

Readiness for changes: New competences for knowledge society

Đurišić-Bojanović Mirosava

2007-01-01

Full Text Available In the conditions of high instability, uncertainty and changing of environment of contemporary organizations, management of changes and knowledge become priority social strategies, and readiness for changes, flexible usage of knowledge and creativity become the most important competences of people in contemporary organizations. Knowledge, creativity, taking initiative and readiness for changes are the condition of development, survival and success of organizations, but of individuals as well. Our basic question is aimed at the possibilities of the contribution of basic education to the preparation of the young for working in turbulent environment, where work and professional competences involve readiness for changes and innovativeness. In terms of educational policy it implies the need for the creation of upbringing- educational model which will be capable of providing optimal answers to the changes in environment. The key notion of pluralist educational concept, based on democratic values, is the acceptance of the plurality of ideas. Our researches suggest a significant positive correlation between the variables tolerance of independence and the acceptance of the plurality of ideas. Based on that fact, using the theoretical analytical method, this paper argues the compatibility of pluralist concept in education with the demands of contemporary organizations from the perspective of preparing the young for the inclusion in work in the uncertain, changeable organizational environment of knowledge society.

Arctic Climate Change, Economy and Society (ACCESS): Integrated perspectives.

Crépin, Anne-Sophie; Karcher, Michael; Gascard, Jean-Claude

2017-12-01

This introduction to the special issue presents an overview of the wide range of results produced during the European Union project Arctic Climate Change, Economy and Society (ACCESS). This project assessed the main impacts of climate change on Arctic Ocean's geophysical variables and how these impending changes could be expected to impact directly and indirectly on socio-economic activities like transportation, marine sea food production and resource exploitation. Related governance issues were examined. These results were used to develop several management tools that can live on beyond ACCESS. In this article, we synthesize most of the project results in the form of tentative responses to questions raised during the project. By doing so, we put the findings of the project in a broader perspective and introduce the contributions made in the different articles published in this special issue.

Sea-level rise caused by climate change and its implications for society

MIMURA, Nobuo

2013-01-01

Sea-level rise is a major effect of climate change. It has drawn international attention, because higher sea levels in the future would cause serious impacts in various parts of the world. There are questions associated with sea-level rise which science needs to answer. To what extent did climate change contribute to sea-level rise in the past? How much will global mean sea level increase in the future? How serious are the impacts of the anticipated sea-level rise likely to be, and can human society respond to them? This paper aims to answer these questions through a comprehensive review of the relevant literature. First, the present status of observed sea-level rise, analyses of its causes, and future projections are summarized. Then the impacts are examined along with other consequences of climate change, from both global and Japanese perspectives. Finally, responses to adverse impacts will be discussed in order to clarify the implications of the sea-level rise issue for human society. PMID:23883609

Rapid changes in the range limits of Scots pine 4000 years ago

International Nuclear Information System (INIS)

Gear, A.J.; Huntley, B.

1991-01-01

Paleoecological data provide estimates of response rates to past climate changes. Fossil Pinus sylvestris stumps in far northern Scotland demonstrate former presence of pine trees where conventional pollen evidence of pine forests is lacking. Radiocarbon, dendrochronological, and fine temporal-resolution palynological data show that pine forest were present for about four centuries some 4,000 years ago; the forests expanded and then retreated rapidly some 70 to 80 kilometers. Despite the rapidity of this response to climate change, it occurred at rates slower by an order of magnitude than those necessary to maintain equilibrium with forecast climate changes attributed to the greenhouse effect

Medical rehabilitation in low and middle income countries for adult acquired disability: challenges posed by rapidity of health system change and position on the individualistic-collectivist axis

Directory of Open Access Journals (Sweden)

Karl Sandin

2015-01-01

Full Text Available Chronic illness prevalence has rapidly increased in low or middle income countries (LMIC and with it, the need for medical rehabilitation for adults with acquired conditions that stem from aging and long-term conditions. While Western medical rehabilitation programs have had at least two generations to develop, in LMIC, post-acute health care delivery change has been much more rapid. As a result, there has been little opportunity for models of medical rehabilitation to deliberately emerge in LMIC that reflect societal values. While adaptation of an independence-foremost model of medical rehabilitation may succeed in non-Western societies, there is a risk that adaptation of such a model will be ineffective where many value collectivism more than individualism. The rapid change in medical rehabilitation service delivery in LMIC gives Christian providers and organizations an opportunity to pause and reflect whether the dominant Western medical rehabilitation paradigm serves LMIC cultures and reflects Biblical principles.

Ethics of clinician communication in a changing communication landscape: guidance from professional societies.

Gollust, Sarah E; Dwyer, Anne M

2013-12-01

Cancer experts engage in public communication whenever they promote their research or practice, respond to media inquiries, or use social media. In a changing communication landscape characterized by new technologies and heightened attention to cancer controversies, these activities may pose ethical challenges. This study was designed to evaluate existing resources to help clinicians navigate their public communication activities. We conducted a systematic, qualitative content analysis of codes of ethics, policy statements, and similar documents disseminated by professional medical and nursing societies for their members. We examined these documents for four types of content related to public communication: communication via traditional media; communication via social media; other communication to the public, policy, and legal spheres; and nonspecific language regarding public communication. We identified 46 documents from 23 professional societies for analysis. Five societies had language about traditional news media communication, five had guidance about social media, 11 had guidance about other communication domains, and 15 societies offered general language about public communication. The limited existing guidance focused on ethical issues related to patients (such as privacy violations) or clinicians (such as accuracy and professional boundaries), with less attention to population or policy impact of communication. Cancer-related professional societies might consider establishing more specific guidance for clinicians concerning their communication activities in light of changes to the communication landscape. Additional research is warranted to understand the extent to which clinicians face ethical challenges in public communication.

Space and commodity-based society

Directory of Open Access Journals (Sweden)

Gvozden Vladimir

2015-01-01

Full Text Available The space is privileged in the commodity-based society. It is well known that the economic space in the 19th and 20th centuries rapidly managed to subordinate all other areas 'conveying and instilling in them their own meanings and goals' (G. Milatović. A new form of space that qualifies commodity society was created, marked by dualities: openness-closeness, private-public, sameness-difference. This paper is an attempt to criticize the usual analysis of the categories of commodity-space, linked to the ambivalent role of the state as a guarantor of the functioning of the commodity-based society, as well as its controlling instance. The increasing delocalisation of the political changes the nature of the space in the commodity-based society. Privileged areas are produced that create an illusion of protection of consumers (shopping malls, gated communities, theme parks, video surveillance, while at the same time social differentiation and identification are produced through the symbolic order of commodities and a sense of inclusion or exclusion from that order. At the same time, the examples of tourism and selling places demonstrate that such a commodity-space unusually easy reconciles sameness and difference. It entails uniformity to help achieve the fluctuation of goods, while insisting on the local as different, especially in terms of the role of particularity in the global trade.

Rapid Change Detection Algorithm for Disaster Management

Michel, U.; Thunig, H.; Ehlers, M.; Reinartz, P.

2012-07-01

This paper focuses on change detection applications in areas where catastrophic events took place which resulted in rapid destruction especially of manmade objects. Standard methods for automated change detection prove not to be sufficient; therefore a new method was developed and tested. The presented method allows a fast detection and visualization of change in areas of crisis or catastrophes. While often new methods of remote sensing are developed without user oriented aspects, organizations and authorities are not able to use these methods because of absence of remote sensing know how. Therefore a semi-automated procedure was developed. Within a transferable framework, the developed algorithm can be implemented for a set of remote sensing data among different investigation areas. Several case studies are the base for the retrieved results. Within a coarse dividing into statistical parts and the segmentation in meaningful objects, the framework is able to deal with different types of change. By means of an elaborated Temporal Change Index (TCI) only panchromatic datasets are used to extract areas which are destroyed, areas which were not affected and in addition areas where rebuilding has already started.

Climate change will affect individuals with pre-existing respiratory disease, but the extent of the effect remains unclear. The present position statement was developed on behalf of the European Respiratory Society in order to identify areas of concern arising from climate change for individuals with respiratory disease, healthcare workers in the respiratory sector and policy makers. The statement was developed following a 2-day workshop held in Leuven (Belgium) in March 2008. Key areas of concern for the respiratory community arising from climate change are discussed and recommendations made to address gaps in knowledge. The most important recommendation was the development of more accurate predictive models for predicting the impact of climate change on respiratory health. Respiratory healthcare workers also have an advocatory role in persuading governments and the European Union to maintain awareness and appropriate actions with respect to climate change, and these areas are also discussed in the position statement.

Rapid change of field line connectivity and reconnection in stochastic magnetic fields

International Nuclear Information System (INIS)

Huang, Yi-Min; Bhattacharjee, A.; Boozer, Allen H.

2014-01-01

Magnetic fields without a direction of continuous symmetry have the generic feature that neighboring field lines exponentiate away from each other and become stochastic, and hence the ideal constraint of preserving magnetic field line connectivity becomes exponentially sensitive to small deviations from ideal Ohm's law. The idea of breaking field line connectivity by stochasticity as a mechanism for fast reconnection is tested with numerical simulations based on reduced magnetohydrodynamics equations with a strong guide field line-tied to two perfectly conducting end plates. Starting from an ideally stable force-free equilibrium, the system is allowed to undergo resistive relaxation. Two distinct phases are found in the process of resistive relaxation. During the quasi-static phase, rapid change of field line connectivity and strong induced flow are found in regions of high field line exponentiation. However, although the field line connectivity of individual field lines can change rapidly, the overall pattern of field line mapping appears to deform gradually. From this perspective, field line exponentiation appears to cause enhanced diffusion rather than reconnection. In some cases, resistive quasi-static evolution can cause the ideally stable initial equilibrium to cross a stability threshold, leading to formation of intense current filaments and rapid change of field line mapping into a qualitatively different pattern. It is in this onset phase that the change of field line connectivity is more appropriately designated as magnetic reconnection. Our results show that rapid change of field line connectivity appears to be a necessary, but not a sufficient condition for fast reconnection.

New Roles for Scientists and Science Societies to Improve Science Communication

Science.gov (United States)

Schneider, S. H.

2008-12-01

Should North American Scientists and Science Societies continue with current communication programs or is there a need for expanded and or altered roles in Science Communication? If current practices are working, why is discourse outside of science societies so often misinformed and distorted on environmental change issues that are clearly defined and described within the science community? Climate change is one example there is virtual unanimity and overwhelming evidence from the scientific community that the Earth is warming rapidly and humans are an important cause, but there is confusion in the media and the public, in part due to disinformation campaigns by greenhouse gas polluters and privately funded "Think Tanks." A summary discussion will be presented that addresses many of the ideas and issues brought forward by colleagues in science, science communication and education. Scientists and Science Societies must re-establish objectivity in science information communication to educators, the media and the public. Recommendations on directions will be a key outcome of this presentation.

Adapting to climate change and global change have become vital goals for all societies. These same societies are faced at times with unexpected meteorological phenomena that are becoming increasingly frequent and intense, including flooding, droughts and tornadoes. They are also having to wrestle with rising temperatures and the follow-on effects on the balance of ecosystems, the evolution of species, and animal and plant life, not to mention the development of human populations, their living conditions and social organisation. Although the capacity of ecosystems to adapt or convert has been demonstrated by studies on climate variations over time, the growing pace of some phenomena may well lead to a point of no return. In fact, with the global rise in temperature - caused by human activities in particular - we might already have reached this stage. This book, which consists of some fifty articles by scientists and experts, is unique. It makes us think about what lies behind the notions of adaptation and mal-adaptation, drawing on several disciplines, sectors and regional fields. It also highlights the checks and limitations of adaptation, as well as reflecting and suggesting ways of acting and adjusting. The contributions made to this work serve to reinforce the implementation of the Paris Climate Agreement (2015), especially the COP 23 climate conference (23. Conference of the Parties to the United Nations Framework Convention on Climate Change, Bonn, 2017), where adaptation, its objectives and financing, are some of the priorities. This book is the result of a partnership between the CNRS and Comite 21. It was jointly edited by Agathe Euzen (deputy scientific director at the CNRS Ecology and Environment Institute); Bettina Laville (state councillor and Comite 21 chair); and Stephanie Thiebault (director of the CNRS Ecology and Environment Institute)

Towards a tipping point in responding to change: rising costs, fewer options for Arctic and global societies.

Huntington, Henry P; Goodstein, Eban; Euskirchen, Eugénie

Climate change incurs costs, but government adaptation budgets are limited. Beyond a certain point, individuals must bear the costs or adapt to new circumstances, creating political-economic tipping points that we explore in three examples. First, many Alaska Native villages are threatened by erosion, but relocation is expensive. To date, critically threatened villages have not yet been relocated, suggesting that we may already have reached a political-economic tipping point. Second, forest fires shape landscape and ecological characteristics in interior Alaska. Climate-driven changes in fire regime require increased fire-fighting resources to maintain current patterns of vegetation and land use, but these resources appear to be less and less available, indicating an approaching tipping point. Third, rapid sea level rise, for example from accelerated melting of the Greenland ice sheet, will create a choice between protection and abandonment for coastal regions throughout the world, a potential global tipping point comparable to those now faced by Arctic communities. The examples illustrate the basic idea that if costs of response increase more quickly than available resources, then society has fewer and fewer options as time passes.

Numerous researchers discuss of the collapse of civilizations in response to abrupt climate change in the Mediterranean region. The period between 6500 and 5000 cal yr BP is one of the least studied episodes of rapid climate change at the end of the Late Neolithic. This period is characterized by a dramatic decline in settlement and a cultural break in the Balkans. High-resolution paleoenvironmental proxy data obtained in the Lower Angitis Valley enables an examination of the societal responses to rapid climatic change in Greece. Development of a lasting fluvio-lacustrine environment followed by enhanced fluvial activity is evident from 6000 cal yr BP. Paleoecological data show a succession of dry events at 5800-5700, 5450 and 5000-4900 cal yr BP. These events correspond to incursion of cold air masses to the eastern Mediterranean, confirming the climatic instability of the middle Holocene climate transition. Two periods with farming and pastural activities (6300-5600 and 5100-4700 cal BP) are evident. The intervening period is marked by environmental changes, but the continuous occurrence of anthropogenic taxa suggests the persistence of human activities despite the absence of archaeological evidence. The environmental factors alone were not sufficient to trigger the observed societal changes.

The Chinese experience of rapid modernization: sociocultural changes, psychological consequences?

2016-04-01

Full Text Available Mainland China has undergone profound changes dating back to the nineteenth century, including a contemporary period of rapid modernization that began in the 1980s. The result has been dramatic social, cultural, and economic shifts impacting the daily lives of Chinese people. In this paper, we explore the psychological implications of sociocultural transformation in China, emphasizing two central themes. First, rising individualism: findings from social and developmental psychology suggest that China’s rapid development has been accompanied by ever-increasing adherence to individualistic values. Second, rising rates of depression: findings from psychiatric epidemiology point to increasing prevalence of depression over this same time period, particularly in rural settings. We argue that links between sociocultural and psychological shifts in China can be usefully studied through a cultural psychology lens, emphasizing the mutual constitution of culture, mind, and brain. In particular, we note that the link between social change, individualism, and rising mental illness deserves careful attention. Our review suggests that shifting values and socialization practices shape emotion norms of concealment and display, with implications for depressive symptom presentation. The challenge comes with interpretation. Increasing prevalence rates of depression may indeed be a general response to the rapidity of sociocultural change, or a specific consequence of rising individualism—but may also result from increasingly ‘Western’ patterns of symptom presentation, or improvements in diagnostic practice. We conclude by considering the challenges posed to standard universal models of psychological phenomena.

Nursing Leadership in a Rapidly Aging Society: Implications of “The Future of Nursing” Report in Japan

Directory of Open Access Journals (Sweden)

Harue Masaki

2012-01-01

Full Text Available The recent US Institute of Medicine (IOM report about the future of nursing highlights the areas where nurses can serve, contribute, and move forward to improve health care in the United States. Japanese nursing scholars examined the IOM report for its implications in the Japanese context and explored the future of nursing in Japan. The purpose of this paper is to provide support for the premise that the report’s recommendations could have implications for the future of nursing outside of the United States, especially in Japan. Particular areas and activities by nurses in Japan will be presented as examples of nurses taking leadership in designing care for the rapidly aging society of Japan.

Water, climate change and society in Bangladesh

Dhaka, the capital of Bangladesh with a population of over 17 million people, is among the top five coastal cities most vulnerable to climate change, with over 30 % of the population living in slums. Effective disaster mitigation and adaptation requires an understanding how hazards such as flooding impact the population. The impacts of climate change on flooding and thus livelihoods in the complex delta of the Ganges-Brahmaputra-Meghna rivers can not be treated isolated from other anthropogenic impacts due to e.g. the construction of dams as well as a growing population. We illustrate this by setting up a conceptual socio-hydrological causal network using the enhanced Driving force - Pressure - State - Impact - Response framework. The constructed socio-hydrological framework includes both natural and anthropogenic processes and their two-way feedbacks, allowing policy makers to know where available resources can be used effectively to increase resilience and reduce vulnerability. We conclude that climate change takes place over long stretches of time and thus enable the population of Bangladesh to adapt slowly. Resources such as social capital, which is one of the main tools for slum dwellers to be able to cope with flooding can be altered over time, and as such the system can be considered overall stable and resilient. However, transboundary water sharing issues during the dry season and other implications resulting from dam structures such as Farakka Barrage complicate a prognosis on how the rapidly growing population will be affected in the 21st century. This is particularly important in connection with previous findings, which suggest that the Greater Dhaka population already experience a significant increase in mortality during droughts. Climate change can thus be seen as an anthropogenic amplification of the socio-hydrological challenges already faced by Bangladesh today.

Climate Change and Morality: Students' perspectives on the individual and society

Science.gov (United States)

Sternäng, Li; Lundholm, Cecilia

2011-05-01

There is a growing interest in addressing moral aspects in the research and education of socio-scientific issues. This paper investigates students' interpretations of climate change from a moral perspective. The students were 14 years old, studying at Green Schools in the Beijing area, China. The study was based on semi-structured group interviews and the data were analysed from an intentional perspective, which means that both cognitive and situational aspects were taken into consideration in the analysis. Previous research has revealed a close relation between morality and socio-scientific issues and also advocated the need for addressing ethical aspects in science education. However, empirical studies exploring the question of what students' moral reasoning might look like at the individual level have not yet generated enough attention. In this study this is the core focus of interest. The findings show that the students conceptualise the solutions to mitigating climate change in relation to two different stances. That is, they contextualise the problems and solutions by addressing the individual, where the individual is either 'myself' or 'someone else'. The different notions of the individual become crucial as the students' views and considerations for the environment, as well as society, change according to the different contexts. From a moral point of view, the students seem quite unaware of their varying consideration for others, the environment and society. The paper ends with a discussion of implications for practice and research.

Equity in health in unequal societies: meeting health needs in contexts of social change.

Science.gov (United States)

Bloom, G

2001-09-01

The paper explores the implications for health policy of the segmentation of society into social groups with very different levels of income and wealth. Discourses on equity in health are presently dominated by a debate between 'European' and 'American' models of health delivery. This has led to a focus on ideal outcomes rather than practical options for organising and financing health services in poor countries undergoing rapid change. The paper argues for a more explicit acknowledgement of the dynamic character of health development and the political nature of the negotiations regarding the use of government powers. Unregulated markets for health care are neither equitable nor efficient. Government must play a role in supporting the organisation of health services used by different social groups. Countries with low levels of inequality may be able to provide universal access to relatively sophisticated health services. Otherwise, governments need to operate within a segmented system. This means the negotiation of strategies to reduce the burden of sickness and premature death, whilst meeting the needs of different social groups. The discussion is organised in terms of the powers of government to require individuals and institutions to transfer resources for social uses, enforce regulations and generate and disseminate information. The paper concludes that governments committed to equity-enhancing health development need to increase their capacity to facilitate coalition building and manage change. It proposes an international public health legal framework that might include a definition of minimum standards for certain health services, to be underwritten by national and international financial commitments.

Understanding rapid theoretical change in particle physics: a month-by-month co-citation analysis

While co-citation analysis has proved a powerful tool in the study of changes in intellectual foci in science, no one has ever used the technique to study very rapid changes in the theoretical structure of a scientific field. This paper presents month-by-month co-citation analyses of key phases in the weak-electromagnetic unification research program within particle physics, and shows that these analyses capture and illuminate very rapid intellectual changes. These data provide yet another illustration of the utility of co-citation analysis for understanding the history of science. 8 figures

Climate change is broadly recognized as a key environmental issue affecting social and ecological systems worldwide. At the Cancun summit of the United Nations Framework Convention on Climate Change's 16th Conference, the parties jointly agreed that the vulnerable groups particularly in developing countries and whose livelihood is based on land use practices are the most common victims as in most cases their activities are shaped by the climate. Therefore, solving the climate dilemma through mitigation processes and scientific research is an ethical concern. Thus combining the knowledge systems of the societies and scientific evidences can greatly assist in the creation of coping mechanisms for sustainable development in a situation of changing climate. International Humboldt Kolleg focusing on ''knowledge systems of societies and Climate Change'' was organized at ISEC. This event was of unique importance, as the year 2011-12 was celebrated as the 60th Anniversary of Diplomatic Relations between India and Germany with the motto ''Germany and India - Infinite Opportunities.'' This volume is the outcome of the papers presented during the IHK 2011 at ISEC, India. It reports on the present knowledge systems in a third world country which has always practiced a live and let live philosophy. Furthermore it provides valuable information for understanding the complexity of socio-ecological systems in relation to the projected impacts of climate change.

Rapid area change in pitch-up manoeuvres of small perching birds.

Polet, D T; Rival, D E

2015-10-26

Rapid pitch-up has been highlighted as a mechanism to generate large lift and drag during landing manoeuvres. However, pitching rates had not been measured previously in perching birds, and so the direct applicability of computations and experiments to observed behaviour was not known. We measure pitch rates in a small, wild bird (the black-capped chickadee; Poecile atricapillus), and show that these rates are within the parameter range used in experiments. Pitching rates were characterized by the shape change number, a metric comparing the rate of frontal area increase to acceleration. Black-capped chickadees increase the shape change number during perching in direct proportion to their total kinetic and potential energy at the start of the manoeuvre. The linear relationship between dissipated energy and shape change number is in accordance with a simple analytical model developed for two-dimensional pitching and decelerating airfoils. Black-capped chickadees use a wing pitch-up manoeuvre during perching to dissipate energy quickly while maintaining lift and drag through rapid area change. It is suggested that similar pitch-and-decelerate manoeuvres could be used to aid in the controlled, precise landings of small manoeuvrable air vehicles.

Holocene Demographic Changes and the Emergence of Complex Societies in Prehistoric Australia.

Directory of Open Access Journals (Sweden)

Alan N Williams

Full Text Available A continental-scale model of Holocene Australian hunter-gatherer demography and mobility is generated using radiocarbon data and geospatial techniques. Results show a delayed expansion and settlement of much of Australia following the termination of the late Pleistocene until after 9,000 years ago (or 9ka. The onset of the Holocene climatic optimum (9-6ka coincides with rapid expansion, growth and establishment of regional populations across ~75% of Australia, including much of the arid zone. This diffusion from isolated Pleistocene refugia provides a mechanism for the synchronous spread of pan-continental archaeological and linguistic attributes at this time (e.g. Pama-Nyungan language, Panaramitee art style, backed artefacts. We argue longer patch residence times were possible at the end of the optimum, resulting in a shift to more sedentary lifestyles and establishment of low-level food production in some parts of the continent. The onset of El Niño - Southern Oscillation (ENSO; 4.5-2ka restricted low-level food production, and resulted in population fragmentation, abandonment of marginal areas, and reduction in ranging territory of ~26%. Importantly, climate amelioration brought about by more pervasive La Niña conditions (post-2ka, resulted in an intensification of the mobility strategies and technological innovations that were developed in the early- to mid-Holocene. These changes resulted in population expansion and utilization of the entire continent. We propose that it was under these demographically packed conditions that the complex social and religious societies observed at colonial contact were formed.

Neurogenomics and the role of a large mutational target on rapid behavioral change.

Science.gov (United States)

Stanley, Craig E; Kulathinal, Rob J

2016-11-08

Behavior, while complex and dynamic, is among the most diverse, derived, and rapidly evolving traits in animals. The highly labile nature of heritable behavioral change is observed in such evolutionary phenomena as the emergence of converged behaviors in domesticated animals, the rapid evolution of preferences, and the routine development of ethological isolation between diverging populations and species. In fact, it is believed that nervous system development and its potential to evolve a seemingly infinite array of behavioral innovations played a major role in the successful diversification of metazoans, including our own human lineage. However, unlike other rapidly evolving functional systems such as sperm-egg interactions and immune defense, the genetic basis of rapid behavioral change remains elusive. Here we propose that the rapid divergence and widespread novelty of innate and adaptive behavior is primarily a function of its genomic architecture. Specifically, we hypothesize that the broad diversity of behavioral phenotypes present at micro- and macroevolutionary scales is promoted by a disproportionately large mutational target of neurogenic genes. We present evidence that these large neuro-behavioral targets are significant and ubiquitous in animal genomes and suggest that behavior's novelty and rapid emergence are driven by a number of factors including more selection on a larger pool of variants, a greater role of phenotypic plasticity, and/or unique molecular features present in large genes. We briefly discuss the origins of these large neurogenic genes, as they relate to the remarkable diversity of metazoan behaviors, and highlight key consequences on both behavioral traits and neurogenic disease across, respectively, evolutionary and ontogenetic time scales. Current approaches to studying the genetic mechanisms underlying rapid phenotypic change primarily focus on identifying signatures of Darwinian selection in protein-coding regions. In contrast

Conclusion: The findings of this study indicate that the process of health care in Iranian rural society is changing rapidly with community health workers encountering new challenges. There is diminished efficiency in responding to the changing care process in Iran's rural society. Considering this change in process of care, therefore, the health care system should respond to these new challenges by establishing new health care models.

New type of Piezoresistive Pressure Sensors for Environments with Rapidly Changing Temperature

Directory of Open Access Journals (Sweden)

Tykhan Myroslav

2017-03-01

Full Text Available The theoretical aspects of a new type of piezo-resistive pressure sensors for environments with rapidly changing temperatures are presented. The idea is that the sensor has two identical diaphragms which have different coefficients of linear thermal expansion. Therefore, when measuring pressure in environments with variable temperature, the diaphragms will have different deflection. This difference can be used to make appropriate correction of the sensor output signal and, thus, to increase accuracy of measurement. Since physical principles of sensors operation enable fast correction of the output signal, the sensor can be used in environments with rapidly changing temperature, which is its essential advantage. The paper presents practical implementation of the proposed theoretical aspects and the results of testing the developed sensor.

Degeneration of rapid eye movement sleep circuitry underlies rapid eye movement sleep behavior disorder.

Science.gov (United States)

McKenna, Dillon; Peever, John

2017-05-01

During healthy rapid eye movement sleep, skeletal muscles are actively forced into a state of motor paralysis. However, in rapid eye movement sleep behavior disorder-a relatively common neurological disorder-this natural process is lost. A lack of motor paralysis (atonia) in rapid eye movement sleep behavior disorder allows individuals to actively move, which at times can be excessive and violent. At first glance this may sound harmless, but it is not because rapid eye movement sleep behavior disorder patients frequently injure themselves or the person they sleep with. It is hypothesized that the degeneration or dysfunction of the brain stem circuits that control rapid eye movement sleep paralysis is an underlying cause of rapid eye movement sleep behavior disorder. The link between brain stem degeneration and rapid eye movement sleep behavior disorder stems from the fact that rapid eye movement sleep behavior disorder precedes, in the majority (∼80%) of cases, the development of synucleinopathies such as Parkinson's disease, dementia with Lewy bodies, and multiple system atrophy, which are known to initially cause degeneration in the caudal brain stem structures where rapid eye movement sleep circuits are located. Furthermore, basic science and clinical evidence demonstrate that lesions within the rapid eye movement sleep circuits can induce rapid eye movement sleep-specific motor deficits that are virtually identical to those observed in rapid eye movement sleep behavior disorder. This review examines the evidence that rapid eye movement sleep behavior disorder is caused by synucleinopathic neurodegeneration of the core brain stem circuits that control healthy rapid eye movement sleep and concludes that rapid eye movement sleep behavior disorder is not a separate clinical entity from synucleinopathies but, rather, it is the earliest symptom of these disorders. © 2017 International Parkinson and Movement Disorder Society. © 2017 International Parkinson and

A Learned Society's Perspective on Publishing.

Suzuki, Kunihiko; Edelson, Alan; Iversen, Leslie L; Hausmann, Laura; Schulz, Jörg B; Turner, Anthony J

2016-10-01

Scientific journals that are owned by a learned society, like the Journal of Neurochemistry (JNC), which is owned by the International Society for Neurochemistry (ISN), benefit the scientific community in that a large proportion of the income is returned to support the scientific mission of the Society. The income generated by the JNC enables the ISN to organize conferences as a platform for members and non-members alike to share their research, supporting researchers particularly in developing countries by travel grants and other funds, and promoting education in student schools. These direct benefits and initiatives for ISN members and non-members distinguish a society journal from pure commerce. However, the world of scholarly publishing is changing rapidly. Open access models have challenged the business model of traditional journal subscription and hence provided free access to publicly funded scientific research. In these models, the manuscript authors pay a publication cost after peer review and acceptance of the manuscript. Over the last decade, numerous new open access journals have been launched and traditional subscription journals have started to offer open access (hybrid journals). However, open access journals follow the general scheme that, of all participating parties, the publisher receives the highest financial benefit. The income is generated by researchers whose positions and research are mostly financed by taxpayers' or funders' money, and by reviewers and editors, who frequently are not reimbursed. Last but not least, the authors pay for the publication of their work after a rigorous and sometimes painful review process. JNC itself has an open access option, at a significantly reduced cost for Society members as an additional benefit. This article provides first-hand insights from two former Editors-in-Chief, Kunihiko Suzuki and Leslie Iversen, about the history of JNC's ownership and about the difficulties and battles fought along the way to

A Comparative Study on the Status of Elderly In the Traditional and Modern Societies

2008-10-01

Full Text Available Over the past two centuries, the rapid socio-economic transformations along with substantial advances in medicine have resulted in decrease of mortality rate, the significant increase of life expectancy, and the growth of the population aging. In despite of the increased proportion of elderly in the recent periods, their status has significantly decreased. Elderly in the traditional societies had high levels of mastery and authority, especially power, wealth, and prestige. In the light of these assets, they were able to play the vital role in both family and society. However, experiencing rapid changes in the society and family at the present time, the status of elderly is no longer as high as before. The falling trend of elderly's status in the modem societies has resulted in the formation of such stereotypes as elder are not able to take part actively in society. It is important to find exact responses to such questions as whether elderly are useless? and how society can profit their potential and actual abilities? In this regard, the first step is the investigation about roots of decreasing status of old people in the modem world. Overall, the literature review shows that the followings are amongst the most important factors affecting the status of elderly in the modem societies: the decreasing importance of traditional values to control social interaction, the increasing role of mass media and new forms of information technologies to transfer knowledge and science, the decreasing demand to elderly' participation in economic activities, the substantial decreasing in the family size and the emergence of nuclear family, the decreasing responsibilities and duties of family as a social institution, the increasing trend of women employment, the increasing generational gap, the increasing value of youth and beauty, and changing the architecture of residences. Since aging is a multidimensional phenomenon, every effort to empowerment of elderly and

Rapid stress-induced transcriptomic changes in the brain depend on beta-adrenergic signaling.

Acute exposure to stressful experiences can rapidly increase anxiety and cause neuropsychiatric disorders. The effects of stress result in part from the release of neurotransmitters and hormones, which regulate gene expression in different brain regions. The fast neuroendocrine response to stress is largely mediated by norepinephrine (NE) and corticotropin releasing hormone (CRH), followed by a slower and more sustained release of corticosterone. While corticosterone is an important regulator of gene expression, it is not clear which stress-signals contribute to the rapid regulation of gene expression observed immediately after stress exposure. Here, we demonstrate in mice that 45 min after an acute swim stress challenge, large changes in gene expression occur across the transcriptome in the hippocampus, a region sensitive to the effects of stress. We identify multiple candidate genes that are rapidly and transiently altered in both males and females. Using a pharmacological approach, we show that most of these rapidly induced genes are regulated by NE through β-adrenergic receptor signaling. We find that CRH and corticosterone can also contribute to rapid changes in gene expression, although these effects appear to be restricted to fewer genes. These results newly reveal a widespread impact of NE on the transcriptome and identify novel genes associated with stress and adrenergic signaling. Copyright © 2016 Elsevier Ltd.

Factors Affecting Physician Satisfaction and Wisconsin Medical Society Strategies to Drive Change.

Science.gov (United States)

Coleman, Michele; Dexter, Donn; Nankivil, Nancy

2015-08-01

Physicians' dissatisfaction in their work is increasing, which is affecting the stability of health care in America. The Wisconsin Medical Society (Society) surveyed 1016 Wisconsin physicians to determine the source of their dissatisfaction. The survey results indicate Wisconsin physicians are satisfied when it comes to practice environment, work-life balance, and income. In addition, they are extremely satisfied when it comes to rating their ability to provide high quality care, and they have identified some benefits related to the adoption of electronic health records. However, they are feeling burned out, very unsatisfied with the amount of time spent in direct patient care compared to indirect patient care, and that they are spending too much time on administrative and data entry tasks. In terms of future workforce, many physicians are either unsure or would not recommend the profession to a prospective medical student. Electronic health records serve as both a satisfier and dissatisfier and as a potential driver for future physician satisfaction interventions. Changes at the institutional, organizational, and individual levels potentially could address the identified dissatisfiers and build upon the satisfiers. The Society identifies 12 strategies to improve upon the physician experience.

Rapid Structural Design Change Evaluation with AN Experiment Based FEM

Science.gov (United States)

Chu, C.-H.; Trethewey, M. W.

1998-04-01

The work in this paper proposes a dynamic structural design model that can be developed in a rapid fashion. The approach endeavours to produce a simplified FEM developed in conjunction with an experimental modal database. The FEM is formulated directly from the geometry and connectivity used in an experimental modal test using beam/frame elements. The model sacrifices fine detail for a rapid development time. The FEM is updated at the element level so the dynamic response replicates the experimental results closely. The physical attributes of the model are retained, making it well suited to evaluate the effect of potential design changes. The capabilities are evaluated in a series of computational and laboratory tests. First, a study is performed with a simulated cantilever beam with a variable mass and stiffness distribution. The modal characteristics serve as the updating target with random noise added to simulate experimental uncertainty. A uniformly distributed FEM is developed and updated. The results show excellent results, all natural frequencies are within 0·001% with MAC values above 0·99. Next, the method is applied to predict the dynamic changes of a hardware portal frame structure for a radical design change. Natural frequency predictions from the original FEM differ by as much as almost 18% with reasonable MAC values. The results predicted from the updated model produce excellent results when compared to the actual hardware changes, the first five modal natural frequency difference is around 5% and the corresponding mode shapes producing MAC values above 0·98.

Climate change is anticipated to alter the production, use, release, and fate of environmental chemicals, likely leading to increased uncertainty in exposure and human health risk predictions. Exposure science provides a key connection between changes in climate and associated health outcomes. The theme of the 2015 Annual Meeting of the International Society of Exposure Science—Exposures in an Evolving Environment—brought this issue to the fore. By directing attention to questions that may affect society in profound ways, exposure scientists have an opportunity to conduct “consequential science”—doing science that matters, using our tools for the greater good and to answer key policy questions, and identifying causes leading to implementation of solutions. Understanding the implications of changing exposures on public health may be one of the most consequential areas of study in which exposure scientists could currently be engaged. In this paper, we use a series of case studies to identify exposure data gaps and research paths that will enable us to capture the information necessary for understanding climate change-related human exposures and consequent health impacts. We hope that paper will focus attention on under-developed areas of exposure science that will likely have broad implications for public health. PMID:27485992

Changes in DNA methylation fingerprint of Quercus ilex trees in response to experimental field drought simulating projected climate change.

Rico, L; Ogaya, R; Barbeta, A; Peñuelas, J

2014-03-01

Rapid genetic changes in plants have been reported in response to current climate change. We assessed the capacity of trees in a natural forest to produce rapid acclimation responses based on epigenetic modifications. We analysed natural populations of Quercus ilex, the dominant tree species of Mediterranean forests, using the methylation-sensitive amplified polymorphism (MSAP) technique to assess patterns and levels of methylation in individuals from unstressed forest plots and from plots experimentally exposed to drought for 12 years at levels projected for the coming decades. The percentage of hypermethylated loci increased, and the percentage of fully methylated loci clearly decreased in plants exposed to drought. Multivariate analyses exploring the status of methylation at MSAP loci also showed clear differentiation depending on stress. The PCA scores for the MSAP profiles clearly separated the genetic from the epigenetic structure, and also significantly separated the samples within each group in response to drought. Changes in DNA methylation highlight the large capacity of plants to rapidly acclimate to changing environmental conditions, including trees with long life spans, and our results demonstrate those changes. These changes, although unable to prevent the decreased growth and higher mortality associated with this experimental drought, occurred together with a dampening in such decreases as the long-term treatment progressed. © 2013 German Botanical Society and The Royal Botanical Society of the Netherlands.

Health care managers find their work increasingly difficult, due in part to rapid environmental change that plagues organizational life. Management practices and attitudes that may have been appropriate in previous eras are ineffective today. A study was conducted among managers in the Ministry of Health, State of Bahrain, seeking information about current trends in the macro or external environment that affect the Ministry of Health, as well as internal environmental pressures that may be similar or different. This article provides a clear picture of the context in which managers perform their work and offers recommendations for coping with change in dynamic, complex organizations.

Anthropogenic climate change is rapidly becoming one of the main threats to biodiversity, along with other threats triggered by human-driven land-use change. Species are already responding to climate change by shifting their distributions polewards. This shift may create a spatial mismatch between dynamic species distributions and static protected areas (PAs). As protected areas represent one of the main pillars for preserving biodiversity today and in the future, it is important to assess their contribution in sheltering the biodiversity communities, they were designated to protect. A recent development to investigate climate-driven impacts on biological communities is represented by the community temperature index (CTI). CTI provides a measure of the relative temperature average of a community in a specific assemblage. CTI value will be higher for assemblages dominated by warm species compared with those dominated by cold-dwelling species. We here model changes in the CTI of Finnish bird assemblages, as well as changes in species densities, within and outside of PAs during the past four decades in a large boreal landscape under rapid change. We show that CTI has markedly increased over time across Finland, with this change being similar within and outside PAs and five to seven times slower than the temperature increase. Moreover, CTI has been constantly lower within than outside of PAs, and PAs still support communities, which show colder thermal index than those outside of PAs in the 1970s and 1980s. This result can be explained by the higher relative density of northern species within PAs than outside. Overall, our results provide some, albeit inconclusive, evidence that PAs may play a role in supporting the community of northern species. Results also suggest that communities are, however, shifting rapidly, both inside and outside of PAs, highlighting the need for adjusting conservation measures before it is too late. © 2016 John Wiley & Sons Ltd.

Risoe National Laboratory - Forty years of research in a changing society

Nielsen, H.; Nielsen, K.; Petersen, F.; Siggaard Jensen, H.

1998-01-01

The creation of Risoe forty years ago was one of the largest, single investments in Danish research. The intention was to realise Niels Bohr's visions of the peaceful use in Denmark og nuclear energy for electricity production and other purposes. Risoe decided to take the opportunity of its 40th anniversary in 1998 to have its history written in a form that would contribute to the history of modern Denmark. The result was a book in Danish entitled Til samfundets tarv - Forskningscenter Risoes historie. The present text is a slightly reworked translation of the last chapter of that book. It contains a summary of Risoe's history and some reflections on forty years of change. Change in Danish society at large, in research policy, in energy policy, in technological expectations. Changes at Risoe, in leadership, in organisational structure, in strategy and in fields of research. Some of Risoe's largest projects are briefly characterised. (LN)

The present volume contains the speeches and discussion reports of the 29th Trier colloquium on the environmental and techniques law, which was dedicated to the theme ''Energy change in the industrial society''. The goal a the colloquium consisted, to work out central questions of the energy change and also to look beyond the legal field. The documented speeches deal mainly with the promotional system of the renewal-energy law and its need for reform, whereby this topic is discussed from legal, economic, and business perspective. A further main topic form questions of planning. Hereby it deals both with the regulation of the increased use of renewable energies in zoning and land-use planning and with the network expansion including public participation. Object of the discussion are also the providing of the base load by conventional power plants as well as legal questions of the compensation and load balancing in the connection of off-shore facilities.

The impact of rapid climate change on contemporary human populations is of global concern. To contextualize our understanding of human responses to rapid climate change it is necessary to examine the archeological record during past climate transitions. One episode of abrupt climate change has been correlated with societal collapse at the end of the northwestern European Bronze Age. We apply new methods to interrogate archeological and paleoclimate data for this transition in Ireland at a higher level of precision than has previously been possible. We analyze archeological (14)C dates to demonstrate dramatic population collapse and present high-precision proxy climate data, analyzed through Bayesian methods, to provide evidence for a rapid climatic transition at ca. 750 calibrated years B.C. Our results demonstrate that this climatic downturn did not initiate population collapse and highlight the nondeterministic nature of human responses to past climate change.

Rapid Cultural Change: A Case Study of Polyandry Marriage System among the Gurung Community from Upper Mustang, Nepal

Full Text Available Nepal is multi ethnic, multi lingual and multi cultural country. In Upper Mustang polyandry is practiced by Loba communities. However, the condition of polyandry is dying out at present. The young are not in favor of this system. Socio-economic, political, seasonal migration, tourism and developmental factors have played crucial role in this regards. From conservation perspective polyandry played crucial role to manage local resources and in population dynamics in the past. This paper is based on field survey carried out in two different time periods (1998 and 2008 in order to compare or understand changing pattern of polyandry. In last couple of years, polyandry system has changed very rapidly in Loba communities of Upper Mustang. Rising community awareness, multiple economic opportunities, improve communication, foreign employment, modern education, open tourism, road access and other visual and in visual forces has lead society from close to open and more wider side or increase the horizon of young generation. Polyandry system is directly affected. DOI: http://dx.doi.org/10.3126/dsaj.v6i0.8480 Dhaulagiri Journal of Sociology and Anthropology Vol. 6, 2012 75-106

Climate engineering and the risk of rapid climate change

Ross, Andrew; Damon Matthews, H

2009-01-01

Recent research has highlighted risks associated with the use of climate engineering as a method of stabilizing global temperatures, including the possibility of rapid climate warming in the case of abrupt removal of engineered radiative forcing. In this study, we have used a simple climate model to estimate the likely range of temperature changes associated with implementation and removal of climate engineering. In the absence of climate engineering, maximum annual rates of warming ranged from 0.015 to 0.07 deg. C/year, depending on the model's climate sensitivity. Climate engineering resulted in much higher rates of warming, with the temperature change in the year following the removal of climate engineering ranging from 0.13 to 0.76 deg. C. High rates of temperature change were sustained for two decades following the removal of climate engineering; rates of change of 0.5 (0.3,0.1) deg. C/decade were exceeded over a 20 year period with 15% (75%, 100%) likelihood. Many ecosystems could be negatively affected by these rates of temperature change; our results suggest that climate engineering in the absence of deep emissions cuts could arguably constitute increased risk of dangerous anthropogenic interference in the climate system under the criteria laid out in the United Nations Framework Convention on Climate Change.

Full Text Available This article briefly discusses various definitions and concepts of the so-called information society. The term information society has been proposed to refer to the post-industrial society in which information plays a pivotal role. The definitions that have been proposed over the years highlight five underlying characterisations of an information society: technological, economic, sociological, spatial, and cultural. This article discusses those characteristics. While the emergence of an information society may be just a figment of one’s imagination, the concept could be a good organising principle to describe and analyse the changes of the past 50 years and of the future in the 21st century.

Endogenous change: on cooperation and water availability in two ancient societies

Science.gov (United States)

Pande, S.; Ertsen, M.

2014-05-01

We propose and test the theory of endogenous change in societal institutions based on historical reconstructions of two ancient civilizations, the Indus and Hohokam, in two water-scarce basins, the Indus Basin in the Indian subcontinent and the lower Colorado Basin in the southwestern United States. In our reconstructions, institutions are approximated by the scale of "cooperation", be it in the form of the extent of trade, sophisticated irrigation networks, a central state or a loosely held state with a common cultural identity. We study changes in institutions brought about by changes in factors like rainfall, population density, and land-use-induced water resource availability, in a proximate manner. These factors either change naturally or are changed by humans; in either case we contend that the changes affect the stability of cooperative structures over time. We relate the quantitative dimensions of water access by ancient populations to the co-evolution of water access and the socioeconomic and sociopolitical organizations. In doing so, we do not claim that water manipulation was the single most significant factor in stimulating social development and complexity - this would be highly reductionist. Nonetheless, we provide a discussion with the aim to enhance our understanding of the complexity of coupled human-hydrological systems. We find that scarcity triggered more complex cooperative arrangements in both Indus and Hohokam societies.

Polystyrene (PS) microspheres were synthesized by emulsifier-free emulsion polymerization and arranged in an array of closely packed, opal-like photonic crystals by slow self-assembly through dip-coating. This periodic array of PS microspheres was then employed as a rapid qualitative sensor for methanol and ethanol. Both solvents could be detected rapidly based on the routes of their reflection coordinates in the chromaticity diagram or directly by the naked eye on the basis of the change in color within 1 min once a solvent sample had been placed on the PS photochromic sensor. This opal-like PS sensor can thus not only be employed as a rapid sensor for methanol and ethanol but can also be used as a powerful tool for the fast screening of illicit drugs and toxic chemicals during forensic investigations. - Highlights: • Opal-like array of polystyrene (PS) microspheres is synthesized by self-assembly. • This periodic PS array is used as a rapid sensor for methanol and ethanol. • Solvents are detected by routes of reflection coordinates in chromaticity diagram. • They are also detected directly by naked eye based on change in color of sensor. • The color change is irreversible for methanol but reversible for ethanol.

The American Thoracic Society (ATS), in collaboration with George Mason University, surveyed a random sample of ATS members to assess their perceptions of, clinical experiences with, and preferred policy responses to climate change. An e-mail containing an invitation from the ATS President and a link to an online survey was sent to 5,500 randomly selected U.S. members; up to four reminder e-mails were sent to nonrespondents. Responses were received from members in 49 states and the District of Columbia (n = 915); the response rate was 17%. Geographic distribution of respondents mirrored that of the sample. Survey estimates' confidence intervals were ±3.5% or smaller. Results indicate that a large majority of ATS members have concluded that climate change is happening (89%), that it is driven by human activity (68%), and that it is relevant to patient care ("a great deal"/"a moderate amount") (65%). A majority of respondents indicated they were already observing health impacts of climate change among their patients, most commonly as increases in chronic disease severity from air pollution (77%), allergic symptoms from exposure to plants or mold (58%), and severe weather injuries (57%). A larger majority anticipated seeing these climate-related health impacts in the next 2 decades. Respondents indicated that physicians and physician organizations should play an active role in educating patients, the public, and policy makers on the human health effects of climate change. Overall, ATS members are observing that human health is already adversely affected by climate change and support responses to address this situation.

To date, brain structure and function changes in children with complex regional pain syndrome (CRPS) as a result of disease and treatment remain unknown. Here, we investigated (a) gray matter (GM) differences between patients with CRPS and healthy controls and (b) GM and functional connectivity (FC) changes in patients following intensive interdisciplinary psychophysical pain treatment. Twenty-three patients (13 females, 9 males; average age ± SD = 13.3 ± 2.5 years) and 21 healthy sex- and age-matched controls underwent magnetic resonance imaging. Compared to controls, patients had reduced GM in the primary motor cortex, premotor cortex, supplementary motor area, midcingulate cortex, orbitofrontal cortex, dorsolateral prefrontal cortex (dlPFC), posterior cingulate cortex, precuneus, basal ganglia, thalamus, and hippocampus. Following treatment, patients had increased GM in the dlPFC, thalamus, basal ganglia, amygdala, and hippocampus, and enhanced FC between the dlPFC and the periaqueductal gray, two regions involved in descending pain modulation. Accordingly, our results provide novel evidence for GM abnormalities in sensory, motor, emotional, cognitive, and pain modulatory regions in children with CRPS. Furthermore, this is the first study to demonstrate rapid treatment-induced GM and FC changes in areas implicated in sensation, emotion, cognition, and pain modulation.

WHY THE SUDDEN CHANGE OF THE POLITICAL REGIME IS DETERMINING RISK IN ECONOMY AND SOCIETY?

Full Text Available In this article the authors aim to gather an in-depth understanding of the evolution of manking throughout the history and its political regimes, and in the same time are analizing and determining the components of the social function that exercised a great influence on the stability and dynamics of the production and consumption, pointing out that any social organization that wants to remain rational should have as a primary objective the happiness of the people, that so called,“general happiness”, that could only be achieved through education, culture, raising people's moral and intellectual knowledge. Since any political system does not seek the general good, but the one of some persons or a specific group of people, there is only very little communion between them and the people or is entirely missing and for these reasons their reign won’t be long, because the people are always wanting a political change. This "social problem" occurred because of some significant social movements, socialist doctrines whose effects still persist in present times. The efforts of the profound thinkers and mankind throughout the history, with all the positive developments did not materialize in achieving a society in which wealth is equitably distributed, where the contributions of the people in getting them is equally shared that could satisfy the requirements and the needs of the majority members of the society. In all the transformations and society changes or the political regime of the state, the human being represented the base, with its unlimited evolution and thinking, and all of these were achieved in time and were given by a certain social environment. The human being can not be separated from its social environment. He is born to live in the society, but the freedom can not be unlimited of course. The history has shown that all the hasty attempts suffered the same fate and the only sustainable progress made by the people were those who came out

How Rapid Change Affects Deltas in the Arctic Region

Science.gov (United States)

Overeem, I.; Bendixen, M.

2017-12-01

Deltas form where the river drains into the ocean. Consequently, delta depositional processes are impacted by either changes in the respective river drainage basin or by changes in the regional marine environment. In a warming Arctic region rapid change has occurred over the last few decades in both the terrestrial domain as well as in the marine domain. Important terrestrial controls include 1) change in permafrost possibly destabilizing river banks, 2) strong seasonality of river discharge due to a short melting season, 3) high sediment supply if basins are extensively glaciated, 4) lake outbursts and ice jams favoring river flooding. Whereas in the Arctic marine domain sea ice loss promotes wave and storm surge impact, and increased longshore transport. We here ask which of these factors dominate any morphological change in Arctic deltas. First, we analyze hydrological data to assess change in Arctic-wide river discharge characteristics and timing, and sea ice concentration data to map changes in sea ice regime. Based on this observational analysis we set up a number of scenarios of change. We then model hypothetical small-scale delta formation considering change in these primary controls by setting up a numerical delta model, and combining it dynamically with a permafrost model. We find that for typical Greenlandic deltas changes in river forcing due to ice sheet melt dominate the morphological change, which is corroborated by mapping of delta progradation from aerial photos and satellite imagery. Whereas in other areas, along the North Slope and the Canadian Arctic small deltas are more stable or experienced retreat. Our preliminary coupled model allows us to further disentangle the impact of major forcing factors on delta evolution in high-latitude systems.

Law-making functions of the Chinese courts:Judicial activism in a country of rapid social changes

The judicial production of law and the legislative production of law make a striking distinction between the two legal traditions.Despite of these differences,judges in both legal traditions in adjudicating cases have a common task,which is the application of legal rules to the facts of cases pending for judgments.The tension between the certainty and the "discretion" is universal for any legal system and,to a certain extent,it poses a hard dilemma for the rhetoric of rule of law.In the transitional countries such as China where rapid social changes and transformations take place,the judiciary and judges can not escape from taking more active roles in interpreting or even law making process.It arouses much controversy,particularly in continental legal traditions,for the judiciary is deemed to perform a mechanical role in adjudicating cases.This article intends to analyze the needs for judicial law.making function in China and its reasons.It reveals that judicial interpretation constitutes an important source of law despite its ambiguous legislative position.The article argues that judicial activism is inevitable against the transitional nature of current Chinese society.

The American Thoracic Society (ATS), in collaboration with George Mason University, surveyed international members of the society to assess perceptions, clinical experiences, and preferred policy responses related to global climate change. A recruitment email was sent by the ATS President in October 2015 to 5,013 international members. Subsequently, four reminder emails were sent to nonrespondents. Responses were received from 489 members in 68 countries; the response rate was 9.8%. Half of respondents reported working in countries in Asia (25%) or Europe (25%), with the remainder in South America (18%), North America (Canada and Mexico) (18%), Australia or New Zealand (9%), and Africa (6%). Survey estimate confidence intervals were ± 5% or smaller. A high percentage of international ATS survey respondents judged that climate change is happening (96%), that it is driven by human activity (70%), and that it is relevant to patient care ("a great deal"/"a moderate amount") (80%). A majority of respondents also indicated they are already observing health impacts of climate change among their patients; most commonly as increases in chronic disease severity from air pollution (88%), allergic symptoms from exposure to plants or mold (72%), and severe weather injuries (69%). An even larger majority anticipated seeing these climate-related health impacts in the next two decades. Respondents further indicated that physicians and physician organizations should play an active role in educating patients, the public, and policy makers on the human health effects of climate change. International ATS respondents, like their counterparts in the U.S., observed that human health is already adversely affected by climate change, and support responses to address this situation.

Full Text Available Change existed in various forms in all stages of development of human society, is that we were dealing with in all economic aspects, social, cultural or others, all of which have affected human existence. A complex phenomenon, which occurs in a longer or shorter period of time and which requires humans to be located in the center, through their own will, constituted into a veritable binder between cause and effect, old and new, nature and culture. Today the exchange of cultural information in the context of international system allows groups of people to interact generating complex changes, so it is essential to take into account processes that could limit diversity in evolution. As well as the cultural phenomenon develops by increasing its social size, density and diversity, society will always be interested in the way how every new element changes human individual universe.

Cosmic rays linked to rapid mid-latitude cloud changes

Directory of Open Access Journals (Sweden)

B. A. Laken

2010-11-01

Full Text Available The effect of the Galactic Cosmic Ray (GCR flux on Earth's climate is highly uncertain. Using a novel sampling approach based around observing periods of significant cloud changes, a statistically robust relationship is identified between short-term GCR flux changes and the most rapid mid-latitude (60°–30° N/S cloud decreases operating over daily timescales; this signal is verified in surface level air temperature (SLAT reanalysis data. A General Circulation Model (GCM experiment is used to test the causal relationship of the observed cloud changes to the detected SLAT anomalies. Results indicate that the anomalous cloud changes were responsible for producing the observed SLAT changes, implying that if there is a causal relationship between significant decreases in the rate of GCR flux (~0.79 GU, where GU denotes a change of 1% of the 11-year solar cycle amplitude in four days and decreases in cloud cover (~1.9 CU, where CU denotes a change of 1% cloud cover in four days, an increase in SLAT (~0.05 KU, where KU denotes a temperature change of 1 K in four days can be expected. The influence of GCRs is clearly distinguishable from changes in solar irradiance and the interplanetary magnetic field. However, the results of the GCM experiment are found to be somewhat limited by the ability of the model to successfully reproduce observed cloud cover. These results provide perhaps the most compelling evidence presented thus far of a GCR-climate relationship. From this analysis we conclude that a GCR-climate relationship is governed by both short-term GCR changes and internal atmospheric precursor conditions.

Tracking and unpacking rapid Arctic change: Indicators of community health and sustainability in northern Alaska and links to cryospheric change

Tracking and responding to rapid Arctic change benefits from time series of indicator variables that describe the state of the system and can inform anticipatory action. A key challenge is to identify and monitor sets of indicators that capture relevant variability, trends, and transitions in social-environmental systems. We present findings from participatory scenarios focused on community health and sustainability in northern Alaska. In a series of workshops in 2015 and 2016 (Kotzebue workshop photo shown below), over 50 experts, mostly local, identified determinants of community health and sustainability by 2040 in the Northwest Arctic and North Slope Boroughs, Alaska. Drawing on further research, an initial set of factors and uncertainties was refined and prioritized into a total of 20 key drivers, ranging from governance issues to socio-economic and environmental factors. The research team then developed sets of future projections that describe plausible outcomes by mid-century for each of these drivers. A plausibility and consistency analysis of all pairwise combinations of these projections (following Mueller-Stoffels and Eicken, In: North by 2020 - Perspectives on Alaska's Changing Social-Ecological Systems, University of Alaska Press, 2011) resulted in the identification of robust scenarios. The latter were further reviewed by workshop participants, and a set of indicator variables, including indicators of relevant cryospheric change, was identified to help track trajectories towards plausible future states. Publically accessible recorded data only exist for a subset of the more than 70 indicators, reaching back a few years to several decades. For several indicators, the sampling rate or time series length are insufficient for tracking of and response to change. A core set of variables has been identified that meets indicator requirements and can serve as a tool for Alaska Arctic communities in adapting to or mitigating rapid change affecting community

Rapid modification in the olfactory signal of ants following a change in reproductive status

Cuvillier-Hot, Virginie; Renault, Valérie; Peeters, Christian

2005-02-01

In insect societies, the presence and condition of egg-layers can be assessed with pheromones. Exocrine secretions are expected to vary in time in order to give up-to-date information on an individual’s reproductive physiology. In the queenless monogynous ant Streblognathus peetersi, we allowed a previously infertile high-ranking worker to accede to the alpha rank, thus triggering the onset of her oogenesis (15 replicates). We then studied her interactions with an established egg-layer from the same colony after different durations, ranging from 20 h to several days. Even though her eggs are only ready to be laid after 30 days, the new alpha was recognised within 1 2 days. Detection occurred at a distance of a few millimetres, suggesting the involvement of a pheromone with low volatility, such as cuticular hydrocarbons. When the new alpha had differentiated for >48 h, she was attacked by the established egg-layer. In all cases, low-ranking workers eventually immobilised one of the two alphas: the new alpha was the target if she had differentiated only recently, suggesting that police workers select the dominant worker with the “less fertile” odour. Using the behaviour of ants as our measure, we demonstrate that a dominant’s olfactory signal changes rapidly with a modification in her social status, and it occurs well before the onset of egg-laying.

Honan, Meg

2015-01-01

Places of work have been completely transformed by innovations in mobile work tools and ever-present access to internet data. This article characterizes use patterns and provides preliminary considerations for productive and comfortable use of common mobile devices. Two surveys described trends in mobile work. In the first, ergonomics professionals who oversee programs reported common mobile devices, their users and what data is accessed. The second, an end user survey, explored common activities performed on mobile devices, duration of use and locations where mobile work is common. The survey results provide a baseline data point for the status of mobile work in early 2014. Research indicates that additional risks have been introduced to the neck, thumbs and hands when using mobile devices. Possible trends regarding device use and work locations emerge. Intervention studies provide some direction for the practitioner. Practical strategies are outlined to reduce exposure intensity and duration. Contemporary mobile work presents tremendous change and opportunity for ergonomists and researchers to keep pace with fitting the changing models of work to the person. Continued research is needed on current mobile device use patterns to better understand ergonomic risk exposure in this rapidly changing realm.

Rapid changes in protein phosphorylation associated with gravity perception in corn roots

A previous paper from this laboratory showed calcium- and calmodulin-dependent in vivo protein phosphorylation in corn root tips. The authors show that rapid changes in calcium-dependent protein phosphorylation are involved in light-dependent graviperception in corn root tips. Corn seedlings (Zea mays L, cv Merit) were grown in the dark for 3 d, then apical root segments were harvested in dim green light to measure in vivo protein phosphorylation. Segments were incubated with 0.5 mCi 32 P for 1 h, then immediately frozen in liquid N 2 or first treated with either 7 min light, or 7 min light plus 1 mM EGTA and 10 μM A23187. Labeled proteins were separated by 2D gel electrophoresis and detected by autoradiography. Light caused rapid and specific promotion of phosphorylation of 5 polypeptides. The increases in protein phosphorylation were reversed by treating with EGTA and A23187. The authors postulate that these changes in protein phosphorylation are an essential part of the light-dependent gravity response in Merit roots

Two alcoholic patients in whom computed tomography (CT) demonstrated reversal of fatty infiltration of the liver are described. The rapid reversibility of fatty infiltration can be useful in monitoring alcoholics with fatty livers. Focal fatty infiltration can mimic focal hepatic lesions and repeat scans can be utilized to assess changes in CT attenuation values when this condition is suspected

Rivers rapid assessment protocols and insertion of society in monitoring of water resources

2008-12-01

Full Text Available The degradation of water resources has been detected and changes both institutional and in the legislation have been demanded. The careless use of rivers has ecological changes as direct consequence, causing serious modifications in the landscape and fluvial regime, besides altering the availability of habitats and the trophic composition of the aquatic environment. Pressed by this scenario, scientists have been developing assessment methods that are efficient both for the evaluation itself and for supporting decision taking in the environmental management processes. In this perspective, the objective of this study is to present the Rapid River Assessment Protocols (RAPs and to emphasize how these protocols can promote the community participation in water resources monitoring. The RAPs can used to evaluate in an integrated form the characteristics of a river section according to the conservation or degradation condition of the fluvial environment and it is characterized by its economic viability and easy applicability. In regions with poor financial resources and serious problems of water quality, the RAPs can be used in environmental management programs. By using these protocols, the integration of the community in water resources monitoring generates data which represent the quality of fluvial ecosystems throughout time, without requesting high costs or specialized professionals. The RAPs in a simplified but not simplistic tool, which can be used in activities that aim at promoting a quick and reliable assessment of the “health” of a river.

Okmok is one of the most active volcanoes in the Aleutian Arc. In an effort to improve our ability to detect precursory activity leading to eruption at Okmok, we monitor a recent, and possibly ongoing, GPS-inferred rapid inflation event at the volcano using ambient noise interferometry (ANI). Applying this method, we identify changes in seismic velocity outside of Okmok’s caldera, which are related to the hydrologic cycle. Within the caldera, we observe decreases in seismic velocity that are associated with the GPS-inferred rapid inflation event. We also determine temporal changes in waveform decorrelation and show a continual increase in decorrelation rate over the time associated with the rapid inflation event. Themagnitude of relative velocity decreases and decorrelation rate increases are comparable to previous studies at Piton de la Fournaise that associate such changes with increased production of volatiles and/ormagmatic intrusion within the magma reservoir and associated opening of fractures and/or fissures. Notably, the largest decrease in relative velocity occurs along the intrastation path passing nearest to the center of the caldera. This observation, along with equal amplitude relative velocity decreases revealed via analysis of intracaldera autocorrelations, suggests that the inflation sourcemay be located approximately within the center of the caldera and represent recharge of shallow magma storage in this location. Importantly, there is a relative absence of seismicity associated with this and previous rapid inflation events at Okmok. Thus, these ANI results are the first seismic evidence of such rapid inflation at the volcano.

Van Hemert, Caroline R.; Pearce, John M.; Handel, Colleen M.

2014-01-01

Climate-related environmental changes have increasingly been linked to emerging infectious diseases in wildlife. The Arctic is facing a major ecological transition that is expected to substantially affect animal and human health. Changes in phenology or environmental conditions that result from climate warming may promote novel species assemblages as host and pathogen ranges expand to previously unoccupied areas. Recent evidence from the Arctic and subarctic suggests an increase in the spread and prevalence of some wildlife diseases, but baseline data necessary to detect and verify such changes are still lacking. Wild birds are undergoing rapid shifts in distribution and have been implicated in the spread of wildlife and zoonotic diseases. Here, we review evidence of current and projected changes in the abundance and distribution of avian diseases and outline strategies for future research. We discuss relevant climatic and environmental factors, emerging host–pathogen contact zones, the relationship between host condition and immune function, and potential wildlife and human health outcomes in northern regions.

Defining New Roles for Scientific Professional Organizations in Society?

Science.gov (United States)

Robock, A.; Byrne, J.

2007-12-01

The obfuscation of authentic science information in North America has reached epidemic proportions. The global warming debate is a classic example - there are a virtual unanimity and overwhelming evidence from scientific community that the Earth is warming rapidly and humans are an important cause, but there is confusion in the media and the public, partly as a result of disinformation campaigns by greenhouse gas polluters. Should the role of scientists in informing the public change in response to this? What should be the role of scientific societies, such as the American Geophysical Union, the American Meteorological Society, or the American Association for the Advancement of Science? Should we continue doing what we are doing, or be more proactive in using new technology to educate the public on important scientific issues? Should we devote resources to television advertisements? Should we support ads in the print media? This talk will discuss the pros and cons of individual and group actions in making the case in public for science, and suggest some new directions.

Motion-insensitive rapid configuration relaxometry.

Science.gov (United States)

Nguyen, Damien; Bieri, Oliver

2017-08-01

Triple echo steady state (TESS) uses the lowest steady state configuration modes for rapid relaxometry. Due to its unbalanced gradient scheme, however, TESS is inherently motion-sensitive. The purpose of this work is to merge TESS with a balanced acquisition scheme for motion-insensitive rapid configuration relaxometry, termed MIRACLE. The lowest order steady state free precession (SSFP) configurations are retrieved by Fourier transformation of the frequency response of N frequency-shifted balanced SSFP (bSSFP) scans and subsequently processed for relaxometry, as proposed with TESS. Accuracy of MIRACLE is evaluated from simulations, phantom studies as well as in vivo brain and cartilage imaging at 3T. Simulations and phantom results revealed no conceptual flaw, and artifact-free configuration imaging was achieved in vivo. Overall, relaxometry results were accurate in phantoms and in good agreement for cartilage and for T2 in the brain, but apparent low T1 values were observed for brain white matter; reflecting asymmetries in the bSSFP profile. Rapid T1 and T2 mapping with MIRACLE offers analogous properties as TESS while successfully mitigating its motion-sensitivity. As a result of the Fourier transformation, relaxometry becomes sensitive to the voxel frequency distribution, which may contain useful physiologic information, such as structural brain integrity. © 2016 International Society for Magnetic Resonance in Medicine.

1998-03-01

Suggestions, most of which are supported by empirical studies, are provided on how total quality management (TQM) teams can be used to bring about faster organizationwide improvements. Ideas are offered on how to identify the right problem, have rapid meetings, plan rapidly, collect data rapidly, and make rapid whole-system changes. Suggestions for identifying the right problem include (1) postpone benchmarking when problems are obvious, (2) define the problem in terms of customer experience so as not to blame employees nor embed a solution in the problem statement, (3) communicate with the rest of the organization from the start, (4) state the problem from different perspectives, and (5) break large problems into smaller units. Suggestions for having rapid meetings include (1) choose a nonparticipating facilitator to expedite meetings, (2) meet with each team member before the team meeting, (3) postpone evaluation of ideas, and (4) rethink conclusions of a meeting before acting on them. Suggestions for rapid planning include reducing time spent on flowcharting by focusing on the future, not the present. Suggestions for rapid data collection include (1) sample patients for surveys, (2) rely on numerical estimates by process owners, and (3) plan for rapid data collection. Suggestions for rapid organizationwide implementation include (1) change membership on cross-functional teams, (2) get outside perspectives, (3) use unfolding storyboards, and (4) go beyond self-interest to motivate lasting change in the organization. Additional empirical investigations of time saved as a consequence of the strategies provided are needed. If organizations solve their problems rapidly, fewer unresolved problems may remain.

Risk society and amoral morality

Directory of Open Access Journals (Sweden)

Nedeljković Radica M.

2017-01-01

Full Text Available The modern world is the world of change. Modernity changed all aspects of life in width and depth. The changes are so fast and so many people have impression that they are trapped in a multitude of events that they cannot understand nor control. Instead of society as a system, we are talking about society as a network of different relationships of individuals and social groups. Instead of a harmonious society as a space in which the man resides, developing their potential and needs, we are talking about society as a threatening force that destroys everything in its way as 'Moloch' (Giddens, the 'risk society' (Beck in which the doctrine produced in equal measure the conditions for prosperity, but also the risks and destruction; the simulation of society (Baudrillard which glorifies lies and deceit. Instead of society as a community, we are talking about the disappearance of society (Popper. Can we, therefore, rationally understand and express the world, the world of modernity; this world of profound change resembles the maze in which we are lost and wandering without meaning? Starting with Ulrich Beck and his theory of the risk society, the author points out that the way in which the western civilization started, which is imposed as a mandatory form for the rest of the world, leads to amoral morality. The ideology of progress, which is irrational and without a clear vision and clearly defined values, pushes us into an uncertain future of numerous risks and ever growing individualism. Thus we come to the conviction that without common values, collective values, we are lost in this world of risk. Solidarity and trust are the key values for the stable community, but they are non-existent in the risk society dominated by individualism. In the period of uncertainty in the risk society, only religion provides a healthy basis for communal living. Therefore, the way out of the crisis is not in politics, which is placed at the service of the economy, but

RAPID SPECTRAL CHANGES OF CYGNUS X-1 IN THE LOW/HARD STATE WITH SUZAKU

Rapid spectral changes in the hard X-ray on a timescale down to {approx}0.1 s are studied by applying a ''shot analysis'' technique to the Suzaku observations of the black hole binary Cygnus X-1, performed on 2008 April 18 during the low/hard state. We successfully obtained the shot profiles, covering 10-200 keV with the Suzaku HXD-PIN and HXD-GSO detector. It is notable that the 100-200 keV shot profile is acquired for the first time owing to the HXD-GSO detector. The intensity changes in a time-symmetric way, though the hardness changes in a time-asymmetric way. When the shot-phase-resolved spectra are quantified with the Compton model, the Compton y-parameter and the electron temperature are found to decrease gradually through the rising phase of the shot, while the optical depth appears to increase. All the parameters return to their time-averaged values immediately within 0.1 s past the shot peak. We have not only confirmed this feature previously found in energies below {approx}60 keV, but also found that the spectral change is more prominent in energies above {approx}100 keV, implying the existence of some instant mechanism for direct entropy production. We discuss possible interpretations of the rapid spectral changes in the hard X-ray band.

Urban lighting, light pollution and society

Meier, Josiane; Krause, Katharina; Pottharst, Merle

2014-01-01

After decades "in the shadows", urban lighting is re-emerging as a matter of public debate. Long-standing truths are increasingly questioned as a confluence of developments affects lighting itself and the way it is viewed. Light has become an integral element of place-making and energy-saving initiatives alike. Rapidly evolving lighting technologies are opening up new possibilities, but also posing new challenges to planners, and awareness is growing that artificial illumination is not purely benign but can actually constitute a form of pollution. As a result, public policy frameworks, incentives and initiatives are undergoing a phase of innovation and change that will affect how cities are lit for years to come. The first comprehensive compilation of current scientific discussions on urban lighting and light pollution from a social science and humanities perspective, Urban Lighting, Light Pollution and Society contributes to an evolving international debate on an increasingly controversial topic.

Evolving society and mental health

Full Text Available Numerous issues related to culture, occupation, gender, caste, and health, to name a few, have faced harshness of society from time immemorial. Reasons are debatable, ranging from somewhat understandable to completely unacceptable. There is no doubt that society is dynamic and it has changed its view on many of the issues with passing time. Mental health is one such issue which society has neglected for quite a long time. Even today, mental health and mentally ill people face stigma and discrimination in their family, society, and at their workplace. People do not feel comfortable talking about mental health, even if they know that there cannot be any health without a healthy mind. But, as Albert Einstein has said “learn from yesterday, live for today, and hope for tomorrow”, everything is not lost. The mentally ill patients who were once abandoned and left on their own have now started to get humane care and attention. This article discusses this very pertinent topic of changing society and mental health.

The Canadian Heart Rhythm Society (CHRS) Device Advisory Committee was commissioned to respond to advisories regarding cardiac rhythm device and lead performance on behalf of the CHRS. In the event of an advisory, the Chair uses an e-mail network to disseminate advisory information to Committee members broadly representative of the Canadian device community. A consensus recommendation is prepared by the Committee and made available to all Canadian centres on the CHRS Web site after approval by the CHRS executive. This collaborative approach using an e-mail network has proven very efficient in providing a rapid national response to device advisories. The network is an ideal tool to collect specific data on implanted device system performance and allows for prompt reporting of clinically relevant data to front-line clinicians and patients.

This review describes the summary of the presentation that the authors made on behalf of the Korean Radiological Society in the forum, including the organization, current status of academic activity, current status of international communication, and problems encountered in the internationalization of the Korean Radiological Society

Tropical vegetation evidence for rapid sea level changes associated with Heinrich Events

A Cariaco Basin pollen record shows the development of tropical salt marshes during marine isotope stage 3. Rapid and abrupt expansions of salt marsh vegetation in tropical South America are associated with north Atlantic Heinrich Events stadials (HE-stadials). Intervals of salt marsh expansion have an internal structure, which consists of a recurrent alternation of species that starts with pollen increments of Chenopodiaceae, that are followed by increments of grasses, and subsequently by increments of Cyperaceae. This pattern suggests a successional process that is determined by the close relationship between sea-level and plant community dynamics. The salt tolerant Chenopodiaceae, indicate hypersaline intertidal environments, which were most likely promoted by extremely dry atmospheric conditions. Rapid sea-level rise characterizes the onset of HE-stadials, causing the continued recruitment of pioneer species, which are the only ones tolerating rapid rates of disturbance. Once sea-level rise decelerates, marsh plants are able to trap and stabilize sediments, favouring the establishment of more competitive species. These results add to the scarce knowledge on the dynamics of tropical salt marsh ecosystems, and provide independent paleoclimatic evidence on sea-level changes following Antarctic climate variability.

Main Dynamics of the Transition from Industrial Society to Information Society

Directory of Open Access Journals (Sweden)

Yaşar Tonta

2005-12-01

Full Text Available Industrial Society is based on mass production and mass distribution of standardized goods and services. The objective of companies is to reduce the unit cost by producing and distributing the same goods in large quantities cheaper than their competitors. Mass production and mass distribution requires an economic model based on centralization; mechanistical, rigid/hierarchical organizational structures; and traditional education. Companies act on the basis of the logic of “produce, store, and sell”. Information Society on the other hand is an indication of a more complex and richer social structure. The objective of companies is to produce mass customized and personalized goods and services for their customers. The customer can buy a personalized good or service with the best price from anywhere in the world. Called “The Age of Terrific Deal” by Robert B. Reich, Information Society requires an economic model based on personalization; dynamic and flat organizational structures; and customer focused education. Companies must act on the basis of the logic of “sell, produce, and deliver”. This paper discusses the major changes that take place during the transition from Industrial Society to Information Society along with basic dynamics of the Information Society.

Integrated ocean management as a strategy to meet rapid climate change: the Norwegian case.

Science.gov (United States)

Hoel, Alf Håkon; Olsen, Erik

2012-02-01

The prospects of rapid climate change and the potential existence of tipping points in marine ecosystems where nonlinear change may result from them being overstepped, raises the question of strategies for coping with ecosystem change. There is broad agreement that the combined forces of climate change, pollution and increasing economic activities necessitates more comprehensive approaches to oceans management, centering on the concept of ecosystem-based oceans management. This article addresses the Norwegian experience in introducing integrated, ecosystem-based oceans management, emphasizing how climate change, seen as a major long-term driver of change in ecosystems, is addressed in management plans. Understanding the direct effects of climate variability and change on ecosystems and indirect effects on human activities is essential for adaptive planning to be useful in the long-term management of the marine environment.

Two hundred and seven Japanese elementary school children aged from 6 (Grade 1) to 12 (Grade 6) years old were tested for their abilities to name numbers and pictured objects along with reading Hiragana characters and words. These children all showed typical development and their classroom teachers judged that they were not having any problems with reading or writing. The children were randomly divided into two groups, the first group was assigned to two naming tasks;the rapid automatized naming (RAN) of "numbers" and "pictured objects," the second group was assigned to two rapid alternative stimulus (RAS) naming tasks using numbers and pictured objects. All children were asked to perform two reading tasks that were written in Hiragana script: single mora reading task and four syllable word reading task. The total articulation time for naming and reading and performance in terms of accuracy were measured for each task. Developmental changes in these variables were evaluated. The articulation time was significantly longer for the first graders, and it gradually shortened as they moved through to the upper grades in all tasks. The articulation time reached a plateau in the 5th grade for the number naming, while gradual change continued after drastic change in the lower grades for the pictured object naming. The articulation times for the single mora reading and RAN of numbers correlated strongly. The articulation time for the RAS naming was significantly longer compared to that for the RAN, though there were very few errors. The RAS naming showed the highest correlation with the four syllable word reading. This study demonstrated that the performance in rapid automatized naming of numbers and pictures were closely related with performance on reading tasks. Thus Japanese children with reading disorders such as developmental dyslexia should also be evaluated for rapid automatized naming.

Faculty experiences with rapid integration of male nursing students within a patriarchal societal context.

Science.gov (United States)

Kulakac, Ozen; Arslan, Ilkay; Sucu Dag, Gülten; O'Lynn, Chad

2015-11-01

In 2007, reforms by the Turkish government forced a rapid integration of male nursing students into previously all-female schools. The minimal amount of time for faculty preparation, little guidance from nursing leaders and the extant literature, and a societal context of patriarchy created unique challenges for faculty. The purpose of this qualitative study was to explore and interpret the experiences of nursing faculty as they adapted to the sudden inclusion of men in schools of nursing. A qualitative descriptive study Nine schools from six regions across Turkey 99 nursing faculty who were 22 to 55years of age, primarily female (97.8%), married (65.6%). Focus groups were used to collect data. Data were analyzed using constant comparison and tripartite discussion. Analysis yielded three categories, seven themes, and seven subthemes describing variable experiences, perceptions, and adaptive strategies. The findings presented contradictions characterized by both optimism and concern following the rapid infusion of men into schools of nursing. Concerns primarily centered on the state of gender relations in a larger patriarchal society. The findings foster reflection and discourse as societies characterized by relatively rigid and traditional gender roles confront rapid cultural change and growing calls for diversity within nursing.

Stress recovery may prove to be a promising approach to increase plant performance and, theoretically, mRNA instability may facilitate faster recovery. Transcriptome (RNA-seq, qPCR, sRNA-seq, and PARE) and methylome profiling during repeated excess-light stress and recovery was performed at intervals as short as 3 min. We demonstrate that 87% of the stress-upregulated mRNAs analyzed exhibit very rapid recovery. For instance, HSP101 abundance declined 2-fold every 5.1 min. We term this phenomenon rapid recovery gene downregulation (RRGD), whereby mRNA abundance rapidly decreases promoting transcriptome resetting. Decay constants ( k ) were modeled using two strategies, linear and nonlinear least squares regressions, with the latter accounting for both transcription and degradation. This revealed extremely short half-lives ranging from 2.7 to 60.0 min for 222 genes. Ribosome footprinting using degradome data demonstrated RRGD loci undergo cotranslational decay and identified changes in the ribosome stalling index during stress and recovery. However, small RNAs and 5'-3' RNA decay were not essential for recovery of the transcripts examined, nor were any of the six excess light-associated methylome changes. We observed recovery-specific gene expression networks upon return to favorable conditions and six transcriptional memory types. In summary, rapid transcriptome resetting is reported in the context of active recovery and cellular memory. © 2017 American Society of Plant Biologists. All rights reserved.

Methoxychlor and Vinclozolin Induce Rapid Changes in Intercellular and Intracellular Signaling in Liver Progenitor Cells.

Methoxychlor (MXC) and vinclozolin (VIN) are well-recognized endocrine disrupting chemicals known to alter epigenetic regulations and transgenerational inheritance; however, non-endocrine disruption endpoints are also important. Thus, we determined the effects of MXC and VIN on the dysregulation of gap junctional intercellular communication (GJIC) and activation of mitogen-activated protein kinases (MAPKs) in WB-F344 rat liver epithelial cells. Both chemicals induced a rapid dysregulation of GJIC at non-cytotoxic doses, with 30 min EC50 values for GJIC inhibition being 10 µM for MXC and 126 µM for VIN. MXC inhibited GJIC for at least 24 h, while VIN effects were transient and GJIC recovered after 4 h. VIN induced rapid hyperphosphorylation and internalization of gap junction protein connexin43, and both chemicals also activated MAPK ERK1/2 and p38. Effects on GJIC were not prevented by MEK1/2 inhibitor, but by an inhibitor of phosphatidylcholine-specific phospholipase C (PC-PLC), resveratrol, and in the case of VIN, also, by a p38 inhibitor. Estrogen (ER) and androgen receptor (AR) modulators (estradiol, ICI 182,780, HPTE, testosterone, flutamide, VIN M2) did not attenuate MXC or VIN effects on GJIC. Our data also indicate that the effects were elicited by the parental compounds of MXC and VIN. Our study provides new evidence that MXC and VIN dysregulate GJIC via mechanisms involving rapid activation of PC-PLC occurring independently of ER- or AR-dependent genomic signaling. Such alterations of rapid intercellular and intracellular signaling events involved in regulations of gene expression, tissue development, function and homeostasis, could also contribute to transgenerational epigenetic effects of endocrine disruptors. © The Author 2016.

Rapid Hip Osteoarthritis Development in a Patient with Anterior Acetabular Cyst with Sagittal Alignment Change

Directory of Open Access Journals (Sweden)

Yasuhiro Homma

2014-01-01

Full Text Available Rapidly destructive coxarthrosis (RDC is rare and develops unusual clinical course. Recent studies suggest multiple possible mechanisms of the development of RDC. However the exact mechanism of RDC is still not clear. The difficulty of the study on RDC is attributed to its rareness and the fact that the data before the onset of RDC is normally unavailable. In this report, we presented the patient having the radiographic data before the onset who had rapid osteoarthritis (OA development after contralateral THA, which meets the current criteria of RDC. We thought that the increased posterior tilt of the pelvis after THA reinforced the stress concentration at pre-existed anterior acetabular cyst, thereby the destruction of the cyst was occurred. As a result the rapid OA was developed. We think that there is the case of rapid osteoarthritis developing due to alternating load concentration by posterior pelvic tilt on preexisting anterior acetabular cyst such as our patient among the cases diagnosed as RDC without any identifiable etiology. The recognition of sagittal alignment changes and anterior acetabular cyst may play important role in prediction and prevention of the rapid hip osteoarthritis development similar to RDC.

Humans are ecosystems containing trillions of microorganisms, but the evolutionary history of this microbiome is obscured by a lack of knowledge about microbiomes of African apes. We sequenced the gut communities of hundreds of chimpanzees, bonobos, and gorillas and developed a phylogenetic approach to reconstruct how present-day human microbiomes have diverged from those of ancestral populations. Compositional change in the microbiome was slow and clock-like during African ape diversification, but human microbiomes have deviated from the ancestral state at an accelerated rate. Relative to the microbiomes of wild apes, human microbiomes have lost ancestral microbial diversity while becoming specialized for animal-based diets. Individual wild apes cultivate more phyla, classes, orders, families, genera, and species of bacteria than do individual humans across a range of societies. These results indicate that humanity has experienced a depletion of the gut flora since diverging from Pan.

Evolution under changing climates: climatic niche stasis despite rapid evolution in a non-native plant.

Alexander, Jake M

2013-09-22

A topic of great current interest is the capacity of populations to adapt genetically to rapidly changing climates, for example by evolving the timing of life-history events, but this is challenging to address experimentally. I use a plant invasion as a model system to tackle this question by combining molecular markers, a common garden experiment and climatic niche modelling. This approach reveals that non-native Lactuca serriola originates primarily from Europe, a climatic subset of its native range, with low rates of admixture from Asia. It has rapidly refilled its climatic niche in the new range, associated with the evolution of flowering phenology to produce clines along climate gradients that mirror those across the native range. Consequently, some non-native plants have evolved development times and grow under climates more extreme than those found in Europe, but not among populations from the native range as a whole. This suggests that many plant populations can adapt rapidly to changed climatic conditions that are already within the climatic niche space occupied by the species elsewhere in its range, but that evolution to conditions outside of this range is more difficult. These findings can also help to explain the prevalence of niche conservatism among non-native species.

1981-01-01

Double labeling methods were used to identify changes in the complement of proteins synthesized in the retinal ganglion cells and transported down the optic nerve during the process of axonal regeneration. Eight to 62 days after goldfish underwent a unilateral optic nerve crush, one eye was labeled with [3H]-, the other with [14C]proline. Control and regenerating optic nerves were dissected out and homogenized together after 5 hr, a time which allowed us to examine selectively membrane-bound components which migrate in the rapid phase of axoplasmic transport. Proteins from the two sides were so-purified and separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Analysis of the 3H and 14C incorporation patterns along the gels revealed a radical shift away from the normal labeling spectrum during regeneration, with selective changes in labeling at particular molecular weights varying over a 3-fold range. Eight days after crushing the optic nerve, the greatest increases in labeling were seen for material with apparent molecular weights of 24,000 to 27,000, 44,000, and 210,000 daltons. These peaks declined thereafter, and on days 29 to 39, the most prominent increases were at 110,000 to 140,000 daltons. These studies indicate a continuously changing pattern in the synthesis and/or degradation of proteins that are rapidly transported down the optic nerve during regeneration and point to molecular species potential significance in the establishment of the visual map upon the brain

Rapidly Assessing Changes in Bone Mineral Balance Using Natural Stable Calcium Isotopes

We demonstrate that variations in the Ca isotope ratios in urine rapidly and quantitatively reflect changes in bone mineral balance. This variation occurs because bone formation depletes soft tissue of light Ca isotopes, while bone resorption releases that isotopically light Ca back into soft tissue. In a study of 12 individuals confined to bed rest, a condition known to induce bone resorption, we show that Ca isotope ratios shift in a direction consistent with net bone loss after just 7 days, long before detectible changes in bone density occur. Consistent with this interpretation, the Ca isotope variations track changes observed in N-teleopeptide, a bone resorption biomarker, while bone-specific alkaline phosphatase, a bone formation biomarker, is unchanged. Ca isotopes can in principle be used to quantify net changes in bone mass. Ca isotopes indicate an average loss of 0.62 +/- 0.16 % in bone mass over the course of this 30-day study. The Ca isotope technique should accelerate the pace of discovery of new treatments for bone disease and provide novel insights into the dynamics of bone metabolism.

More rapid climate change promotes evolutionary rescue through selection for increased dispersal distance.

Boeye, Jeroen; Travis, Justin M J; Stoks, Robby; Bonte, Dries

2013-02-01

Species can either adapt to new conditions induced by climate change or shift their range in an attempt to track optimal environmental conditions. During current range shifts, species are simultaneously confronted with a second major anthropogenic disturbance, landscape fragmentation. Using individual-based models with a shifting climate window, we examine the effect of different rates of climate change on the evolution of dispersal distances through changes in the genetically determined dispersal kernel. Our results demonstrate that the rate of climate change is positively correlated to the evolved dispersal distances although too fast climate change causes the population to crash. When faced with realistic rates of climate change, greater dispersal distances evolve than those required for the population to keep track of the climate, thereby maximizing population size. Importantly, the greater dispersal distances that evolve when climate change is more rapid, induce evolutionary rescue by facilitating the population in crossing large gaps in the landscape. This could ensure population persistence in case of range shifting in fragmented landscapes. Furthermore, we highlight problems in using invasion speed as a proxy for potential range shifting abilities under climate change.

Exploratory of society

2012-11-01

A huge flow of quantitative social, demographic and behavioral data is becoming available that traces the activities and interactions of individuals, social patterns, transportation infrastructures and travel fluxes. This has caused, together with innovative computational techniques and methods for modeling social actions in hybrid (natural and artificial) societies, a qualitative change in the ways we model socio-technical systems. For the first time, society can be studied in a comprehensive fashion that addresses social and behavioral complexity. In other words we are in the position to envision the development of large data and computational cyber infrastructure defining an exploratory of society that provides quantitative anticipatory, explanatory and scenario analysis capabilities ranging from emerging infectious disease to conflict and crime surges. The goal of the exploratory of society is to provide the basic infrastructure embedding the framework of tools and knowledge needed for the design of forecast/anticipatory/crisis management approaches to socio technical systems, supporting future decision making procedures by accelerating the scientific cycle that goes from data generation to predictions.

Rapid change of ion energy distribution and floating potential at L/H transition in the JFT-2M tokamak

Miura, Y.; Nagashima, K.; Okano, F.

1994-01-01

Rapid changes of the main ion energy distribution at transitions from L-to-H, H-to-L and during ELMs are studied with the time of flight neutral measurement in the JFT-2M tokamak. The change of the main ion energy distribution after sawtooth crash during an L-mode phase is also studied. The change of the ion energy distribution just after sawtooth crash is the same as that at L/H-transition. The floating potential measured in the SOL also shows the rapid jump to more positive just after the sawtooth crash (at the same time of the change of an ion energy distribution). This shows the increase of ion outflux in the SOL and might correspond to the change of the ion energy distribution. This may be the reason why most of H-modes are triggered by a sawtooth. (author)

The unaware radioactive material(URM) appeared in the society may induce serious deterministic effect, even result in havoc and instability of the society. The rapid and accurate identification for URM is the premise for its reasonable treatment. In this paper, an identification procedure for URM was developed and which was successfully implemented in the identification of an URM. The In-situ HPGe gamma spectrometry etc was employed for the rapid preliminary identification, and the laboratory HPGe gamma spectrometry and ICP-MS as well as the density measurement were used for its final identification. One unaware radioactive material was assayed, and the results indicate that it is a kind of high pure depleted uranium metal with the 235 U/ 238 U atomic ratio of 0.454%. (authors)

The Common Rule is a set of ethical principles that provide guidance on the management of human subjects taking part in biomedical and behavioral research in the United States. The elements of the Common Rule were initially developed in 1981 following a revision of the Declaration of Helsinki in 1975. Most academic facilities follow the Common Rule in the regulation of clinical trials research. Recently, the government has suggested a revision of the Common Rule to include more contemporary and streamlined oversight of clinical research. In this commentary, the leadership of the Society for Immunotherapy of Cancer (SITC) provides their opinion on this plan. While the Society recognizes the considerable contribution of clinical research in supporting progress in tumor immunotherapy and supports the need for revisions to the Common Rule, there is also some concern over certain elements which may restrict access to biospecimens and clinical data at a time when high throughput technologies, computational biology and assay standardization is allowing major advances in understanding cancer biology and providing potential predictive biomarkers of immunotherapy response. The Society values its professional commitment to patients for improving clinical outcomes with tumor immunotherapy and supports continued discussion with all stakeholders before implementing changes to the Common Rule in order to ensure maximal patient protections while promoting continued clinical research at this historic time in cancer research.

This study is a report of a study to clarify the role of the public health nurse in one Irish community care area in the light of acknowledged problems in defining boundaries of the role. Demographic developments and planned reorientation towards primary care of the health service in Ireland have changed the workload of public health nurses, which is unique compared with other countries. However, there is a lack of clarity and consequent problems in defining the role of the Irish public health nurse. A descriptive qualitative study was conducted with 25 representatives of community nursing from one county in Ireland with a population of 209,077 and a complement of 65 full-time equivalent public health nurses. Purposive sampling was used and 21 public health nurses, two registered general nurses, one assistant director and one school nurse participated. Tape-recorded, individual semi-structured interviews were conducted over a 15-month period from 2002 to 2004. The constant comparative method was used for analysis. Four themes emerged: 'Jack of all trades: the role of the public health nurse defined and described', 'the essence of the role', 'challenges to the role of the public health nurse' and 'communication'. The first theme is discussed in this paper. Public health nurses need to define and redesign their role so that they no longer think that they are the catch-all service in the community. This will enable them to deal with the rapid demographic, sociological and cultural changes in the population, a change that has international resonance.

Full Text Available The knowledge society is defined by multiculturalism, by variety in forms of expression and content. To understand the process of building social networks and new styles of cultural expression that are being developed, it is necessary to participate and experience what we are trying to teach. From school, we are talking about a reality that we do not know. A reality that is changing rapidly, where its true creators: young people, do not talk about it, but live and transform it. The acceptance from the education of different ways of comunication and exchange between students, could make easier the development and help us to harness the resources of the Internet, a network rich in expression, creativity and communication.

The de­velopment of capitalism inevitably leads to changes in the socio­political order of the whole modern world. This leads to the fact that the disappearance of the traditional elements of culture, crafts, songs and dances, rites, destroyed traditional norms and values, beliefs, moral and ethical values. Instead of the traditional culture is formed by the mass culture, society develops consumption goods and becoming all that you can sell. Marketing is one tool for the formation of a society of consumption, but it also performs other less prominent function transforms the traditional society into a consumer society with its values, mythology, norms and moral principles.

Environmental mercury (Hg) contamination is an urgent global health threat. The complexity of Hg in the environment can hinder accurate determination of ecological and human health risks, particularly within the context of the rapid global changes that are altering many ecological processes, socioeconomic patterns, and other factors like infectious disease incidence, which can affect Hg exposures and health outcomes. However, the success of global Hg-reduction efforts depends on accurate assessments of their effectiveness in reducing health risks. In this paper, we examine the role that key extrinsic and intrinsic drivers play on several aspects of Hg risk to humans and organisms in the environment. We do so within three key domains of ecological and human health risk. First, we examine how extrinsic global change drivers influence pathways of Hg bioaccumulation and biomagnification through food webs. Next, we describe how extrinsic socioeconomic drivers at a global scale, and intrinsic individual-level drivers, influence human Hg exposure. Finally, we address how the adverse health effects of Hg in humans and wildlife are modulated by a range of extrinsic and intrinsic drivers within the context of rapid global change. Incorporating components of these three domains into research and monitoring will facilitate a more holistic understanding of how ecological and societal drivers interact to influence Hg health risks.

Although climate warming is expected to make habitat beyond species' current cold range edge suitable for future colonization, this new habitat may present an array of biotic or abiotic conditions not experienced within the current range. Species' ability to shift their range with climate change may therefore depend on how populations evolve in response to such novel environmental conditions. However, due to the recent nature of thus far observed range expansions, the role of rapid adaptation during climate change migration is only beginning to be understood. Here, we evaluated evolution during the recent native range expansion of the annual plant Dittrichia graveolens, which is spreading northward in Europe from the Mediterranean region. We examined genetically based differentiation between core and edge populations in their phenology, a trait that is likely under selection with shorter growing seasons and greater seasonality at northern latitudes. In parallel common garden experiments at range edges in Switzerland and the Netherlands, we grew plants from Dutch, Swiss, and central and southern French populations. Population genetic analysis following RAD-sequencing of these populations supported the hypothesized central France origins of the Swiss and Dutch range edge populations. We found that in both common gardens, northern plants flowered up to 4 weeks earlier than southern plants. This differentiation in phenology extended from the core of the range to the Netherlands, a region only reached from central France over approximately the last 50 years. Fitness decreased as plants flowered later, supporting the hypothesized benefits of earlier flowering at the range edge. Our results suggest that native range expanding populations can rapidly adapt to novel environmental conditions in the expanded range, potentially promoting their ability to spread. © 2017 John Wiley & Sons Ltd.

Climate variability and climate change

International Nuclear Information System (INIS)

Rind, D.

1990-01-01

Changes of variability with climate change are likely to have a substantial impact on vegetation and society, rivaling the importance of changes in the mean values themselves. A variety of paleoclimate and future climate simulations performed with the GISS global climate model is used to assess how the variabilities of temperature and precipitation are altered as climate warms or cools. In general, as climate warms, temperature variability decreases due to reductions in the latitudinal temperature gradient and precipitation variability increases together with the intensity of the hydrologic cycle. If future climate projections are accurate, the reduction in temperature variability will be minimized by the rapid change in mean temperatures, but the hydrologic variability will be amplified by increased evapotranspiration. Greater hydrologic variability would appear to pose a potentially severe problem for the next century

Building a Sustainable Society: The Necessity to Change the Term 'Consumer'

Directory of Open Access Journals (Sweden)

Sabrina Chakori

2017-10-01

Full Text Available The profit-seeking system leads to many negative environmental impacts. Within this economic system, consumption reflects an important relationship between humans and nature. However, despite the growing international attention to environmental sustainability, our society does not necessarily acknowledge consumerism as the cause of global environmental degradation. Deconstructing the consumption culture and redefining what determines well-being, this paper will attempt to provide a comprehensive overview of the existing definition of people in the economic system. Many authors have defined our role in the economy; however, in terms of customer, citizen-consumer, and socially conscious consumer, most of the literature in this domain remains rooted in consumerism. Consumerism cannot be fixed with further consumerism; therefore this paper discusses the importance of reclaiming our identity and the need to define new terms for people in a new economic system. Any new terms should integrate interests and responsibilities that go beyond simple utility maximization. Moving beyond the term “consumer” will change our worldview. This cultural transformation may help facilitate long-term environmental sustainability.

Full Text Available The inception of Modern England comprises a hundred and fifty years between sixteenth and mid eighteenth centuries. The structural qualities of modern societies of this day occur in this era. The political and economic changes and transformations that England experienced in this period of time are in enormous scale. In this period all social structure and institutions experienced structural change in terms of cultural, economic and political processes. In addition to this in this period the framework of the international system regarding economy and politics is established too. Important qualities of current modern societies are the speed of communication and interaction between its elements, its transformational capacity and the extent of its scope.

Rapid landscape change in 6th century northern Jordan: interdisciplinary geoarchaeological perspectives

Science.gov (United States)

Lucke, Bernhard

2016-04-01

Landscapes of the ancient fertile crescent are considered affected by soil degradation as result of long-term farming since the Neolithic, and impressive ruins of antiquity led to assumptions that their abandonment must have been conntected with reduced agricultural productivity. In this context, a valley fill near the site of Abila of the Decapolis in northern Jordan was apparently deposited largely during the 6th century AD, and provides evidence for a rapid and intense landscape change during the Late Byzantine period. However, an interdisciplinary case study of land use, soil development, and sediments found that the valley fill cannot be connected with large-scale soil erosion in the vicinity of the site. On the one hand, this is indicated by the distribution of soil development and archaeological material as marker of past land use activity in the past, which suggests that the best soils were and still are used intensively. On the other hand, the sediments seem to point to the occurrence of climatic extremes such as heavy floods, the occurrence of soil creep after water saturation, but also a significant shift to aridity which may have triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, possibly connected with the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. Modern analogies of the Pinatubo eruption in 1991 let it seem possible that a volcanic event, perhaps the outbreak of the Ilopango volcano, was connected with these environmental turbulences. Such events cannot be understood by isolated studies: without a broad interdisciplinary framework, single archives are prone to misinterpretation, and our understanding of the environmental history of Abila is still very limited.

Su Qu

Full Text Available One of the most common integrative medicine (IM modalities is yoga and related practices. Previous work has shown that yoga may improve wellness in healthy people and have benefits for patients. However, the mechanisms of how yoga may positively affect the mind-body system are largely unknown. Here we have assessed possible rapid changes in global gene expression profiles in the peripheral blood mononuclear cells (PBMCs in healthy people that practiced either a comprehensive yoga program or a control regimen. The experimental sessions included gentle yoga postures, breathing exercises, and meditation (Sudarshan Kriya and Related Practices--SK&P compared with a control regimen of a nature walk and listening to relaxing music. We show that the SK&P program has a rapid and significantly greater effect on gene expression in PBMCs compared with the control regimen. These data suggest that yoga and related practices result in rapid gene expression alterations which may be the basis for their longer term cell biological and higher level health effects.

The reflection on the social policy of the National Action Party in Baja California since 1989, has lead us to see the new challenges that the Financial Aid to Civil Society Organizations Program presents to the local and state government and the social organizations.

Changing societies and four tasks of schooling: Challenges for strongly differentiated educational systems

Science.gov (United States)

van de Werfhorst, Herman G.

2014-05-01

Changing labour markets, increased calls for selection and excellence, and increased diversity and individualisation have repercussions on how educational systems can prepare youth for work, optimise knowledge production, achieve equality of opportunity, and socialise students into active civic engagement. This paper discusses four central tasks of schooling and examines to what extent societal developments challenge education policy to deliver on the tasks at hand. Particular attention is given to the challenges Europe's strongly diversified educational systems are currently facing. Both the Netherlands and Germany, for example, have been offering vocationally-oriented pathways alongside traditional academic higher education for some time. But today's ongoing changes in job descriptions, mainly due to ever-accelerating technological developments, are causing a risk of skills obsolescence which can only be avoided by continuous upskilling and/or reskilling of a sufficiently flexible workforce. Overcoming differences of intelligence as well as differences of diverse socioeconomic, ethnic and linguistic backgrounds by way of education is another challenge, as is fostering "soft" skills and political awareness. This paper investigates the effectiveness of current education systems in preparing citizens for a functioning modern society.

The American Society of Pediatric Hematology/Oncology (ASPHO) solicited information from division directors and fellowship training program directors to capture pediatric hematology/oncology (PHO) specific workforce data of 6 years (2010-2015), in response to an increase in graduating fellows during that time. Observations included a stable number of physicians and advanced practice providers (APPs) in clinical PHO, an increased proportion of APPs hired compared to physicians, and an increase in training-level first career positions. Rapid changes in the models of PHO care have significant implications to current and future trainees and require continued analysis to understand the evolving discipline of PHO. © 2017 Wiley Periodicals, Inc.

Wiki management a revolutionary new model for a rapidly changing and collaborative world

CERN Document Server

Collins, Rod

2013-01-01

We now live in a "wiki" world where mass collaboration is not only possible-it's often the best solution. Conventional management thought assumes that command-and-control is the most effective way to organize the efforts of large numbers of people, but rapid change and increasing complexity have rendered that model obsolete. As a result, most managers today lack the skills and knowledge needed to succeed in an age when networks are proving smarter and faster than hierarchies. Designing organizations for mass collaboration demands a new and very different model-wiki management.

TECHNOLOGICAL DRIVERS OF (REVOLUTIONARY CHANGE IN MODERN SOCIETIES AND HOW DEVELOPING COUNTRIES MIGHT PRODUCTIVELY RESPOND TO THEM VIA INTENTIONAL, THOUGHTFUL “LEAPFROGGING”

Full Text Available Over the time since he was a fresh graduate student in the early 1980s till now, this academic has seen the world being totally transformed from an analogue into a digital “format”. It all started innocently enough with large computers in rooms doing tedious counting and data-tabulating tasks on Hollerith cards while we humans carried on our analogue lives in relative peace. From 1985-1995, the world did change from an (largely unseen tsunami begun from the small waves made by these nascent digital technologies. By 1995, the CD, audio digital recorders and DVD player had replaced earlier technologies. Computers (of a second or third generation had replaced the typewriter; the Soviet bloc and its (long-decaying governance models were only a bad memory (its economic model undone by technologies and demands of the new “third wave” post-industrial knowledge society. Finally, the worldwide web Internet 2.0 was arriving, which would surely change the means and modes of the communicative acts, affecting the economic, political and social/cultural spheres in turn. Using Kenneth Boulding, Marshall McLuhan and Johan Galtung as sage guides, the paper will outline the transformations these technical inventions wrought in the economic, political and cultural spheres in rapid order over the noted decade, considering how the “developed” world has been affected by these changes, bot negatively and positively. Following this, it will briefly consider how the disruptive effects of the digital revolution experienced can be counter-balanced by looking at how “developing” communities and economies have been able to “leap-frog” barriers in how they use digital technologies for both individual and collective humanistic gain.

Epigenetic Determinism in Science and Society.

Science.gov (United States)

Waggoner, Miranda R; Uller, Tobias

2015-04-03

The epigenetic "revolution" in science cuts across many disciplines, and it is now one of the fastest growing research areas in biology. Increasingly, claims are made that epigenetics research represents a move away from the genetic determinism that has been prominent both in biological research and in understandings of the impact of biology on society. We discuss to what extent an epigenetic framework actually supports these claims. We show that, in contrast to the received view, epigenetics research is often couched in language as deterministic as genetics research in both science and the popular press. We engage the rapidly emerging conversation about the impact of epigenetics on public discourse and scientific practice, and we contend that the notion of epigenetic determinism - or the belief that epigenetic mechanisms determine the expression of human traits and behaviors - matters for understandings of the influence of biology and society on population health.

Observation of reversible, rapid changes in drug susceptibility of hypoxic tumor cells in a microfluidic device

Energy Technology Data Exchange (ETDEWEB)

Germain, Todd; Ansari, Megan; Pappas, Dimitri, E-mail: d.pappas@ttu.edu

2016-09-14

Hypoxia is a major stimulus for increased drug resistance and for survival of tumor cells. Work from our group and others has shown that hypoxia increases resistance to anti-cancer compounds, radiation, and other damage-pathway cytotoxic agents. In this work we utilize a microfluidic culture system capable of rapid switching of local oxygen concentrations to determine changes in drug resistance in prostate cancer cells. We observed rapid adaptation to hypoxia, with drug resistance to 2 μM staurosporine established within 30 min of hypoxia. Annexin-V/Sytox Green apoptosis assays over 9 h showed 78.0% viability, compared to 84.5% viability in control cells (normoxic cells with no staurosporine). Normoxic cells exposed to the same staurosporine concentration had a viability of 48.6% after 9 h. Hypoxia adaptation was rapid and reversible, with Hypoxic cells treated with 20% oxygen for 30 min responding to staurosporine with 51.6% viability after drug treatment for 9 h. Induction of apoptosis through the receptor-mediated pathway, which bypasses anti-apoptosis mechanisms induced by hypoxia, resulted in 39.4 ± 7% cell viability. The rapid reversibility indicates co-treatment of oxygen with anti-cancer compounds may be a potential therapeutic target. - Highlights: • Microfluidic system switches rapidly between normoxia and hypoxia (5 min). • Observation of rapid adaptation of PC3 cells to hypoxia and normoxia (30 min). • Drug susceptibility in tumor cells restored after chip switched to normoxia for 30 min.

A noninvasive biopsy protocol was used to sample plasma and gill tissue in individual sockeye salmon (Oncorhynchus nerka) during the critical life stage associated with spawning-arrival at a spawning channel through senescence to death several days later. Our main objective was to characterize the physiological changes associated with rapid senescence in terms of the physiological stress/cortisol hypersecretion model and the energy exhaustion model. Salmon lived an average of 5 d in the spawning channel, during which time there were three major physiological trends that were independent of sexual status: a large increase in plasma indicators of stress and exercise (i.e., lactate and cortisol), a decrease in the major plasma ions (i.e., Cl(-) and Na(+)) and osmolality, and a decrease in gross somatic energy reserves. Contrary to a generalized stress response, plasma glucose decreased in approximately 2/3 of the fish after arrival, as opposed to increasing. Furthermore, plasma cortisol levels at spawning-ground arrival were not correlated with the degree of ionoregulatory changes during rapid senescence. One mechanism of mortality in some fish may involve the exhaustion of energy reserves, resulting in the inability to mobilize plasma glucose. Sex had a significant modulating effect on the degree of physiological change. Females exhibited a greater magnitude of change for gross somatic energy, osmolality, and plasma concentrations of Cl(-), Na(+), cortisol, testosterone, 11-ketotestosterone, 17,20beta-progesterone, and estradiol. The activity level of an individual on the spawning grounds appeared to influence the degree of some physiological changes during senescence. For example, males that received a greater frequency of attacks exhibited larger net decreases in plasma 11-ketotestosterone while on the spawning grounds. These results suggest that rapid senescence on spawning grounds is influenced by multiple physiological processes and perhaps behavior. This study

and medium sized enterprises in search of inexpensive unskilled labor. The trend in Japanese society has become less egalitarian in recent years than it was in the years of rapid growth. Changes in mid-career, contractual employment, and other diversified practices are encroaching on the model of lifetime employment by and loyalty to a single enterprise. Introduction of foreign workers will be 1 more factor contributing to diversification. The new policy of selective internationalization will have some impact on the status of the existing Korean and Chinese communities in Japan, but by itself it does little to end social, economic, and legal discrimination against members of these groups.

Climate variability and climate change

International Nuclear Information System (INIS)

Rind, D.

1991-01-01

Changes of variability with climate change are likely to have a substantial impact on vegetation and society, rivaling the importance of changes in the mean values themselves. A variety of paleoclimate and future climate simulations performed with the GISS global climate model is used to assess how the variabilities of temperature and precipitation are altered as climate warms or cools. In general, as climate warms, temperature variability decreases due to reductions in the latitudinal temperature gradient and precipitation variability increases together with the intensity of the hydrologic cycle. If future climate projections are accurate, the reduction in temperature variability will be minimized by the rapid change in mean temperatures, but the hydrologic variability will be amplified by increased evapotranspiration. Greater hydrologic variability would appear to pose a potentially severe problem for the next century. 19 refs.; 3 figs.; 2 tabs

Plasma sodium is increased following each meal containing salt. There is an increasing interest in the effects of plasma sodium concentration, and it has been suggested that it may have direct effects on blood pressure (BP) and possibly influences endothelial function. Experimental increases of plasma sodium concentration rapidly raise BP even when extracellular volume falls. Ten patients with end-stage renal failure established on haemodialysis were studied during the first 2 h of dialysis without fluid removal during this period. They were randomized to receive haemodialysis with (i) dialysate sodium concentration prescribed to 135 mmol/L and (ii) 145 mmol/L in random order in a prospective, single-blinded crossover study. BP measurements and blood samples were taken every 30 min. Pre-dialysis sitting BP was 137/76 ± 7/3 mmHg. Lower dialysate sodium concentration (135 mmol/L) reduced plasma sodium concentration [139.49 ± 0.67 to 135.94 ± 0.52 mmol/L (P area under the curve (AUC) 15823.50 ± 777.15 (mmHg)min] compared with 145 mmol/L [AUC 17018.20 ± 1102.17 (mmHg)min], mean difference 1194.70 ± 488.41 (mmHg)min, P < 0.05. There was a significant positive relationship between change in plasma sodium concentration and change in systolic BP. This direct relationship suggests that a fall of 1 mmol/L in plasma sodium concentration would be associated with a 1.7 mmHg reduction in systolic BP (P < 0.05). The potential mechanism for the increase in BP seen with salt intake may be through small but significant changes in plasma sodium concentration.

Recently, attention has been repeatedly drawn to the rapidly increasing effects of human influences and the changing climate. The industrial landscape is seen as an important cause, with industrialisation and increasing energy consumption as well as our consumer society and the volume of traffic. The actual extent and speed of climatic change can only be estimated. The process leading to the current extent of scientific knowledge of climatic change, its possible extent and its effects on the plant and wildlife eco-systems are described in detail. Finally, counter-measures and recommendations for action are discussed. (orig.) [de

Rapid response to cognitive behavior therapy (CBT) for eating disorders (i.e., rapid and substantial change to key eating disorder behaviors in the initial weeks of treatment) robustly predicts good outcome at end-of-treatment and in follow up. The objective of this study was to determine whether rapid response to day hospital (DH) eating disorder treatment could be facilitated using a brief adjunctive CBT intervention focused on early change. 44 women (average age 27.3 [8.4]; 75% White, 6.3% Black, 6.9% Asian) were randomly assigned to 1 of 2 4-session adjunctive interventions: CBT focused on early change, or motivational interviewing (MI). DH was administered as usual. Outcomes included binge/purge frequency, Eating Disorder Examination-Questionnaire and Difficulties in Emotion Regulation Scale. Intent-to-treat analyses were used. The CBT group had a higher rate of rapid response (95.7%) compared to MI (71.4%; p = .04, V = .33). Those who received CBT also had fewer binge/purge episodes (p = .02) in the first 4 weeks of DH. By end-of-DH, CBT participants made greater improvements on overvaluation of weight and shape (p = .008), and emotion regulation (ps .05). The results of this study demonstrate that rapid response can be clinically facilitated using a CBT intervention that explicitly encourages early change. This provides the foundation for future research investigating whether enhancing rates of rapid response using such an intervention results in improved longer term outcomes.

Transformational Change and Regime Shifts in the Circumpolar Arctic

Annika E. Nilsson

2016-11-01

Full Text Available The Arctic is changing rapidly, and there are many indications that the region is in the midst of transformational change. While some of the focus relates to impacts of climate change, rapid economic development and the potential for shifts in political and social structures in the region have also been in the limelight. This article looks at the circumpolar Arctic as a potential case of a regime shift in a large-scale social–ecological system that includes reinforcing feedbacks. A special focus is placed on governance structures, as these play an important role in social negotiations on the relationship between societies and the environment. While climate change is often portrayed as a driver of social change in the Arctic, it does not appear that the ongoing changes in the biophysical features of the Arctic region have rocked current circumpolar governance structures out of kilter. On the contrary, the ongoing climate-related changes, in particular sea ice decline, appear to have reinforced political commitment to existing legal structures. Major past social regime shifts have mainly been related to access to resources and national identity ideology, with political dynamics reinforced at times by military security considerations.

Monitoring Forest Change in Landscapes Under-Going Rapid Energy Development: Challenges and New Perspectives

Directory of Open Access Journals (Sweden)

Paul D. Pickell

2014-07-01

Full Text Available The accelerated development of energy resources around the world has substantially increased forest change related to oil and gas activities. In some cases, oil and gas activities are the primary catalyst of land-use change in forested landscapes. We discuss the challenges associated with characterizing ecological change related to energy resource development using North America as an exemplar. We synthesize the major impacts of energy development to forested ecosystems and offer new perspectives on how to detect and monitor anthropogenic disturbance during the Anthropocene. The disturbance of North American forests for energy development has resulted in persistent linear corridors, suppression of historical disturbance regimes, novel ecosystems, and the eradication of ecological memory. Characterizing anthropogenic disturbances using conventional patch-based disturbance measures will tend to underestimate the ecological impacts of energy development. Suitable indicators of anthropogenic impacts in forests should be derived from the integration of multi-scalar Earth observations. Relating these indicators to ecosystem condition will be a capstone in the progress toward monitoring forest change in landscapes undergoing rapid energy development.

Phase field modeling of rapid crystallization in the phase-change material AIST

2017-07-01

We carry out phase field modeling as a continuum simulation technique in order to study rapid crystallization processes in the phase-change material AIST (Ag4In3Sb67Te26). In particular, we simulate the spatio-temporal evolution of the crystallization of a molten area of the phase-change material embedded in a layer stack. The simulation model is adapted to the experimental conditions used for recent measurements of crystallization rates by a laser pulse technique. Simulations are performed for substrate temperatures close to the melting temperature of AIST down to low temperatures when an amorphous state is involved. The design of the phase field model using the thin interface limit allows us to retrieve the two limiting regimes of interface controlled (low temperatures) and thermal transport controlled (high temperatures) dynamics. Our simulations show that, generically, the crystallization velocity presents a maximum in the intermediate regime where both the interface mobility and the thermal transport, through the molten area as well as through the layer stack, are important. Simulations reveal the complex interplay of all different contributions. This suggests that the maximum switching velocity depends not only on material properties but also on the precise design of the thin film structure into which the phase-change material is embedded.

Full Text Available Urban development is a major cause for eco-degradation in many coastal regions. Understanding urbanization dynamics and underlying driving factors is crucial for urban planning and management. Land-use dynamic degree indices and intensity analysis were used to measure land changes occurred in 1990, 2002, 2009, and 2017 in the coastal zone around Quanzhou bay, which is a rapidly urbanized bay in Southeast China. The comprehensive land-use dynamic degree and interval level intensity analysis both revealed that land change was accelerating across the three time intervals in a three-kilometer-wide zone along the coastal line (zone A, while land change was fastest during the second time interval 2002–2009 in a separate terrestrial area within coastal zone (zone B. Driven by urbanization, built-up gains and cropland losses were active for all time intervals in both zones. Mudflat losses were active except in the first time interval in zone A due to the intensive sea reclamation. The gain of mangrove was active while the loss of mangrove is dormant for all three intervals in zone A. Transition level analysis further revealed the similarities and differences in processes within patterns of land changes for both zones. The transition from cropland to built-up was systematically targeted and stationary while the transition from woodland to built-up was systematically avoiding transition in both zones. Built-up tended to target aquaculture for the second and third time intervals in zone A but avoid Aquaculture for all intervals in zone B. Land change in zone A was more significant than that in zone B during the second and third time intervals at three-level intensity. The application of intensity analysis can enhance our understanding of the patterns and processes in land changes and suitable land development plans in the Quanzhou bay area.

Full Text Available Background due to defining the role of people in the development of society and the almost complete absence of scientific management processes capable of progressive development of both individuals and social communities, and nations, and civilization in general. In order to overcome inherent subjectivist methodology of knowledge, psyholohizatorskyh, hiperpolityzovanyh and utilitarian approach, the authors proposed a three-tier system of business processes of society. The conceptual core of the approach consists in the detection task as logical - mathematical laws of subjects of primary, secondary and higher levels of development, and on the mechanisms of their formation and practice. The solution of the tasks allowed the authors to reveal the structure of both the ascending and descending processes of economic society. Thus, the analysis of individual carriers upward changes as «individual», «individuality», «person» and «personality» showed conditionality determination of their activities with «anthropometric», «ethnic», «demographic» and «ideological» mechanisms. Nature as common carriers downstream changes revealed using correlative related «groups», «group «, «groups» and «communities» whose activity is due to «vitalistic», «education», «professional» and «stratification» mechanisms. To disclose the nature and organization of secondary and higher levels of economic society by the authors introduced the category of «citizen», «heneralista», «human space», «human galactic» ‘formation and development is causing «status», «Persona logical», «humanocentric», «institutional», «cluster», «kontaminatsiyni» and other mechanisms. One of the main achievements of the work, the authors consider the possibility of further development and practical implementation of new quality management processes of economic society based multimodal dialectical logic.

Its appearance is attributed to the industrial stage of human development, which was inherent in the accelerated development of the productive forces, deepening division of labour, development of urbanization processes. Accelerated innovation changes related to scientific and technological progress contributed to the overall socio-economic development of certain countries, improve the living standards of their populations, changed the nature of work, method and way of life, especially evident in the XX century. Urbanization and changes in the settlement system, post-industrial phase of economic development, deepening comprehension of environmental issues and global dimension of humanity, humanization of all spheres of public life. The increase in tourist flows in all regions complicates the management of enterprises, schemes of partnership in the process in tourism, which, among other things, is accompanied by rising levels of consumer education, and therefore their quality requirements for end tourism product, the rapid increase in supply, there is a need to study the characteristics of consumer behaviour, search for existing reserves to build capacity of individual enterprises, isolation and effective use of effective methods and tools of influence on consumer choice of consumers. Development and implementation of an effective mechanism of formation of market supply needs an assessment of consumer behaviour on quantitative and qualitative indicators. The rapid development of tourism, of course, helps determine the types and methods of calculating these indicators. These problems and targeted research are considered in this article.

Full Text Available The Kurdish Resurrection Society (known as Komeley Jiyanewey Kurd was the first political society that was founded after August and September 1941 and following the Anglo-Soviet Invasion of Iran. This society arose from traditional and modern strata of urban Kurdish petty bourgeois in Mahabad. The present study aims at discussing the following questions applying a descriptive-analytical approach and using the historical resources and studies: 1. What is the role of the new social and historical structure of the Iranian Kurdistan in forming the Kurdish Resurrection Society? 2. How did the nationalism discourses of the modern absolutist Pahlavi state result in evolving the ideology of Kurdish Resurrection Society (KRS? The evolution of KRS among the traditional and modern strata was the result of the changes and developments occurred in the structure of social forces in Iranian Kurdistan. These changes took place in the aftermath of modernization-related plans of the modern absolutist Pahlavi state in renewing the social structure and cultural assimilation of this era. This policy provoked a new form of collectivism based upon linguistic and ethnic minorities. In other words, while weakening and isolating the forces of the previous order, modernization paved the social and political ways needed for the emergence of new urban Kurdish forces. The Kurdish leaders and elites, affected by the nationalistic discourse of the modern absolutist Pahlavi state, attempted to provide a new definition of their ethnic identity. Thus, the nationalism discourse of the modern absolutist state led to the emergence of a particularistic nationalism discourse of KRS among the Kurds.

Renewable Energy, Climate Action and Resilient Societies: Accelerating the Global and Local Paradigm Shift

This report has been commissioned by a group of foundations in G20 countries, which have come together under the F20 platform in order to engage with the issue of climate change and sustainability in the context of the G20. The report analyzes the emerging energy transition towards efficient and renewable energy systems at global level and in specific G20 countries. On the basis of this analysis, and of the country specific case-studies that have also been conducted in the report, it provides recommendations for foundations and the G20 aimed at enhancing climate change mitigation and sustainability. Key Messages: 1. The global transition to renewable energy systems is underway and accelerating, driven by a combination of policy interventions, very rapid innovation, particularly the fall in renewable electricity costs, and changing societal priorities in many areas, such as the importance being placed on clean air, green industrial development, and investments in local communities. 2. This transition creates tremendous opportunities for countries and companies to ramp-up a new kind of job creation and economic development based on renewable, efficient energy systems. At the same time, countries and actors, who do not anticipate the shift, could be left behind and lose out economically. The good news is that the necessary tools are there. The main question is whether the social and political will for change can be developed and harnessed at the speed and scope required. 3. An economic shift on the scale and speed required to mitigate climate change cannot be achieved solely from the 'top-down'; it can only be implemented with the buy-in and participation of civil society. Worrying trends of inequality, economic disruption, and the fragmentation and fractiousness of public discourse make obtaining this social buy-in all the more difficult. Civil society must thus be seen as an essential partner of policies to drive a new paradigm of sustainable economic development

Hypoxia is a major stimulus for increased drug resistance and for survival of tumor cells. Work from our group and others has shown that hypoxia increases resistance to anti-cancer compounds, radiation, and other damage-pathway cytotoxic agents. In this work we utilize a microfluidic culture system capable of rapid switching of local oxygen concentrations to determine changes in drug resistance in prostate cancer cells. We observed rapid adaptation to hypoxia, with drug resistance to 2 μM staurosporine established within 30 min of hypoxia. Annexin-V/Sytox Green apoptosis assays over 9 h showed 78.0% viability, compared to 84.5% viability in control cells (normoxic cells with no staurosporine). Normoxic cells exposed to the same staurosporine concentration had a viability of 48.6% after 9 h. Hypoxia adaptation was rapid and reversible, with Hypoxic cells treated with 20% oxygen for 30 min responding to staurosporine with 51.6% viability after drug treatment for 9 h. Induction of apoptosis through the receptor-mediated pathway, which bypasses anti-apoptosis mechanisms induced by hypoxia, resulted in 39.4 ± 7% cell viability. The rapid reversibility indicates co-treatment of oxygen with anti-cancer compounds may be a potential therapeutic target. Copyright © 2016 Elsevier B.V. All rights reserved.

This report provides an analysis of the tools and tactics advocacy groups use to influence policy responses to climate change at international, regional, national and sub-national levels. More than 20 climate networks and their member organisations have contributed to the report with their experiences of advocacy on climate change, including over 70 case studies from a wide range of countries - including many of the poorest - in Africa, Asia, Latin America and the Pacific. These advocacy activities primarily target national governments, but also international and regional processes, donors and the private sector. Analyses and case studies show how civil society plays key roles in pushing for new laws, programmes, policies or strategies on climate change, in holding governments to account on their commitments; in identifying the lack of joined-up government responses to climate change; and in ensuring that national policy making does not forget the poor and vulnerable. The report is the first joint product of the Southern Voices Capacity Building Programme, or for short: Southern Voices on Climate Change.

Television, disordered eating, and young women in Fiji: negotiating body image and identity during rapid social change.

Science.gov (United States)

Becker, Anne E

2004-12-01

Although the relationship between media exposure and risk behavior among youth is established at a population level, the specific psychological and social mechanisms mediating the adverse effects of media on youth remain poorly understood. This study reports on an investigation of the impact of the introduction of television to a rural community in Western Fiji on adolescent ethnic Fijian girls in a setting of rapid social and economic change. Narrative data were collected from 30 purposively selected ethnic Fijian secondary school girls via semi-structured, open-ended interviews. Interviews were conducted in 1998, 3 years after television was first broadcast to this region of Fiji. Narrative data were analyzed for content relating to response to television and mechanisms that mediate self and body image in Fijian adolescents. Data in this sample suggest that media imagery is used in both creative and destructive ways by adolescent Fijian girls to navigate opportunities and conflicts posed by the rapidly changing social environment. Study respondents indicated their explicit modeling of the perceived positive attributes of characters presented in television dramas, but also the beginnings of weight and body shape preoccupation, purging behavior to control weight, and body disparagement. Response to television appeared to be shaped by a desire for competitive social positioning during a period of rapid social transition. Understanding vulnerability to images and values imported with media will be critical to preventing disordered eating and, potentially, other youth risk behaviors in this population, as well as other populations at risk.

Environmental impacts of rapid changes in water level; Milj#Latin Small Letter O With Stroke#konsekvenser av raske vannstandsendringer

Flexible operation and peak regulation of hydropower plants (hydropeaking) leads to rapid changes in water levels and water discharge. Due to an increasing share of intermittent energy sources as wind and solar energy in Norway and Europe, we expect to see more flexible operation and increased use of hydropeaking in Norwegian hydropower plants. Environmental impacts will vary depending on local conditions and hydro operations. Some of the environmental impacts of hydropeaking and rapid changes in water level and discharge are well known, where stranding of fish has been most studied, both nationally and internationally. However, there are large knowledge gaps, and there are very few studies of rivers, lakes, reservoirs and fjords downstream of peaking hydropower plants. This report summarizes the knowledge status and presents results from three Norwegian studies with different physical conditions and hydro operations. Not all previous studies have given clear and unambiguous results, but generally we can summarize as follows: Peaking hydropower plants discharging into rivers have considerable higher potential to cause negative effects on physical and biological conditions compared to hydropower plants discharging into reservoirs, lakes and fjords. If it is technically possible to implement slow changes in hydropower production, it will reduce the negative effects on the entire ecosystem. Reducing the rate of change in water level to less than 13 cm per hour gives a significantly reduced risk for stranding of salmonid fish. As far as we know there are not similarly definite guidelines for increasing water level, or for other fish species than salmonids. Fish are more vulnerable to rapid changes in water level during winter than other seasons in Norway due to the fact that low water temperatures directly and indirectly lead to lower mobility in fish. Hydropeaking and flexible operation not leading to significant changes in wetted area will generally not have greater

An updated history of the Teratology Society.

The 49-year history of the Teratology Society is reviewed. An abbreviated history is outlined in table form, with listings of the Warkany Lectures, the Continuing Education Courses, and officers of the society. The original article was updated to include the years 2000 to 2010. A year-by-year description of the events is given, including the scientific and social content of the annual meetings and changes in the business of the society, in many cases using comments from the past presidents. The valuable and unique diversity of the members is discussed and illustrated, presenting the disciplines and main research areas of the presidents. The number of submitted abstracts and the various categories are tabulated, averaging the number and type over successive periods. A significant increase in the number of abstracts dealing with epidemiology and developmental biology is evident. The society's development is compared to that of a human, and the question was asked by Shephard et al. (2000): Have we reached the maturational stage of old age or senescence, or is the society still maturing gracefully? This question needs further discussion by all the members. By 2010, many positive changes are happening to revitalize the society. During the past 50 years, we have developed the scientific basis to prevent birth defects caused by rubella, alcoholism, and folate deficiency, as well as other prenatal exposures. We are now taking advantage of advances in many fields to begin shaping the Teratology Society of the 21st century. We must now engage in political battles to obtain the resources needed to conduct further research and to implement prevention programs, as well as to provide care and rehabilitation for persons with birth defects. 2010 Wiley-Liss, Inc.

Tradition and modernity in Malay society (1830s-1930s

Directory of Open Access Journals (Sweden)

Khoo Kay Kim

2011-06-01

Full Text Available This study attempts to explicate what happened to the Malays between the turn of the 20th century and the beginning of World War II. This is important to underscore the fact that, contrary to general impressions, Islam did not hold back the progress of the Malays, and that even before World War II, major changes were taking place in Malay society. Modernity in Malay society began to emerge even before World War I. Although the intrusion of British administration to a great extent contributed to socio-economic changes in many parts of the Malay Peninsula, the Muslim intelligentsia were indefatigably urging the Malays to be sensitive to their environment; and one way of keeping abreast of change was to expose themselves to modern education. Malay journalism, Malay literature and the frequent exchange of ideas in the Malay media were characteristics of Malay society beginning from the early 20th century. Politics then was not yet to the fore. As in other societies, there were also conservative elements within that placed obstacles in the way of those who tirelessly pursued change from tradition to modernity.

Social Value Orientation and Capitalism in Societies.

Shahrier, Shibly; Kotani, Koji; Kakinaka, Makoto

2016-01-01

Cooperation and competition are core issues in various fields, since they are claimed to affect the evolution of human societies and ecological organizations. A long-standing debate has existed on how social behaviors and preferences are shaped with culture. Considering the economic environment as part of culture, this study examines whether the ongoing modernization of competitive societies, called "capitalism," affects the evolution of people's social preferences and behaviors. To test this argument, we implemented field experiments of social value orientation and surveys with 1002 respondents for three different areas of Bangladesh: (i) rural, (ii) transitional and (iii) capitalistic societies. The main result reveals that with the evolution from rural to capitalistic societies, people are likely to be less prosocial and more likely to be competitive. In a transitional society, there is a considerable proportion of "unidentified" people, neither proself nor prosocial, implying the potential existence of unstable states during a transformation period from rural to capitalistic societies. We also find that people become more proself with increasing age, education and number of children. These results suggest that important environmental, climate change or sustainability problems, which require cooperation rather than competition, will pose more danger as societies become capitalistic.

Rapidly reversible redox transformation in nanophase manganese oxides at room temperature triggered by changes in hydration.

Science.gov (United States)

Birkner, Nancy; Navrotsky, Alexandra

2014-04-29

Chemisorption of water onto anhydrous nanophase manganese oxide surfaces promotes rapidly reversible redox phase changes as confirmed by calorimetry, X-ray diffraction, and titration for manganese average oxidation state. Surface reduction of bixbyite (Mn2O3) to hausmannite (Mn3O4) occurs in nanoparticles under conditions where no such reactions are seen or expected on grounds of bulk thermodynamics in coarse-grained materials. Additionally, transformation does not occur on nanosurfaces passivated by at least 2% coverage of what is likely an amorphous manganese oxide layer. The transformation is due to thermodynamic control arising from differences in surface energies of the two phases (Mn2O3 and Mn3O4) under wet and dry conditions. Such reversible and rapid transformation near room temperature may affect the behavior of manganese oxides in technological applications and in geologic and environmental settings.

Planetary Habitability and Rapid Environmental Change: The Biological Perspective

Science.gov (United States)

Schulze-Makuch, D.; Fairen, A.; Irwin, L.

2012-12-01

Environmental conditions can change drastically and rapidly during the natural history of a planetary body. We have detailed evidence of these dramatic events from Venus, Earth, Mars, and Titan. Most of these occurrences seem to be triggered by astronomical events such as asteroid impacts or supernova explosions; others are triggered by the planet or moon itself (e.g., supervolcano eruptions). The associated question is always how these events affect the habitability of a planet, particularly the origin and presence of life. Under what conditions would such a drastic event be so catastrophic that it would prohibit the origin of life or be so devastating to existing organisms, that life would not be able to recover and be all but extinguished from a planet? Under what conditions would such an event be positive for the evolution of life, for example spurring life via mass extinctions and associated vacant habitats to the invention of new body plans and higher complexity? Here, we provide insights of what we can learn from the natural history of our own planet, which experienced many environmental disasters and abrupt climate changes, from the impact event that created the Moon to the extinction of the dinosaurs. We apply these insights to other planetary bodies and the question about the presence of life. One example is Mars, which underwent drastic environmental changes at the end of the Noachian period. Assuming that microbial life became established on Mars, could it have survived, perhaps by retreating to environmental niches? Life just starting out would have certainly been more vulnerable to extinction. But how far would it have to have evolved to be more resistant to potential extinction events? Would it have to be global in distribution to survive? Another example is Venus. Should Venus be seen as an example where life, which possibly arose in the first few hundred million years when the planet was still in the habitable zone, would have had no chance to

The founding and early development of the Southern Pediatric Neurology Society was in many ways parallel to that of the Child Neurology Society. The organization started out as the Southern Child Neurology Society but the name was changed at the time of incorporation so as to avoid confusion of identity and purpose with the larger Child Neurology Society. Although there are archives of early days and the later development of the Southern Pediatric Neurology Society, the details have never been set down in a narrative explaining the events that led to the development of the organization. In this paper, we try to produce a written record of the history of the founding and early development of the Southern Pediatric Neurology Society. © The Author(s) 2014.

Effects of landscape change on fish assemblage structure in a rapidly growing metropolitan area in North Carolina, USA

Kennen, J.G.; Chang, M.; Tracy, B.H.

2005-01-01

We evaluated a comprehensive set of natural and land-use attributes that represent the major facets of urban development at fish monitoring sites in the rapidly growing Raleigh-Durham, North Carolina metropolitan area. We used principal component and correlation analysis to obtain a nonredundant subset of variables that extracted most variation in the complete set. With this subset of variables, we assessed the effect of urban growth on fish assemblage structure. We evaluated variation in fish assemblage structure with nonmetric multidimensional scaling (NMDS). We used correlation analysis to identify the most important environmental and landscape variables associated with significant NMDS axes. The second NMDS axis is related to many indices of land-use/land-cover change and habitat. Significant correlations with proportion of largest forest patch to total patch size (r = -0.460, P < 0.01), diversity of patch types (r = 0.554, P < 0.001), and population density (r = 0.385, P < 0.05) helped identify NMDS axis 2 as a disturbance gradient. Positive and negative correlations between the abundance of redbreast sunfish Lepomis auritus and bluehead chub Nocomis leptocephalus, respectively, and NMDS axis 2 also were evident. The North Carolina index of biotic integrity and many of its component metrics were highly correlated with urbanization. These results indicate that aquatic ecosystem integrity would be optimized by a comprehensive integrated management strategy that includes the preservation of landscape function by maximizing the conservation of contiguous tracts of forested lands and vegetative cover in watersheds. ?? 2005 by the American Fisheries Society.

This part is the continuation of the second part on renewable energy sources and forest. The major agricultural products entering the Chinese society from 1980 to 2002 are calculated and analyzed in detail in this paper. The relative political infrastructure and organization of the agricultural production in the rural areas frequently and rapidly changed during the past two decades, making profound impact on the crop structure and yields. The planning and organization of agriculture has been adjusted when prices and market are introduced into agricultural production and the direct planning is restricted. The growth in usage of fertilizers, pesticides and farm-use plastic membrane is revealed. The state farm system as the pioneer of exploring the modernization of agriculture and accumulating experiences is also described

The use of ultrasound in pain medicine for interventional axial, nonaxial, and musculoskeletal pain procedures is rapidly evolving and growing. Because of the lack of specialty-specific guidelines for ultrasonography in pain medicine, an international collaborative effort consisting of members of the Special Interest Group on Ultrasonography in Pain Medicine from the American Society of Regional Anesthesia and Pain Medicine, the European Society of Regional Anaesthesia and Pain Therapy, and the Asian Australasian Federation of Pain Societies developed the following recommendations for education and training in ultrasound-guided interventional pain procedures. The purpose of these recommendations is to define the required skills for performing ultrasound-guided pain procedures, the processes for appropriate education, and training and quality improvement. Training algorithms are outlined for practice- and fellowship-based pathways. The previously published American Society of Regional Anesthesia and Pain Medicine and European Society of Regional Anaesthesia and Pain Therapy education and teaching recommendations for ultrasound-guided regional anesthesia served as a foundation for the pain medicine recommendations. Although the decision to grant ultrasound privileges occurs at the institutional level, the committee recommends that the training guidelines outlined in this document serve as the foundation for educational training and the advancement of the practice of ultrasonography in pain medicine.

On the Road: From Industry 4.0 to Society 4.0

Full Text Available The contribution builds on the desk research approach based mainly on studies performed by leading world´s consultancies and agencies as the World Economic Forum, the World Bank and others, academic research performed e.g. at MIT and Harvard Business School, and other resources, and follows the one presented at the 2016 IMECS conference (Vacek, 2016. It focuses on the deep impact of Industry 4.0 on socio-economic issues resulting in what can be called Society 4.0. The contribution tries to highlight the challenges presented to society, economics and management by technology advancements and draw attention to building of necessary synergies between technology and socio-economic systems. The prevailing emphasize is today devoted to technology issues. According to author´s opinion the rapidly advancing technology, if not accompanied by profound changes in socio-economic systems, can result in weakened social cohesion. Instead of pure technology transfer we should today discuss much broader category of knowledge transfer. Ample attention should be paid to intellectual capital, its protection, assessment, and reporting. This contribution does not pretend to present results of the primary field research. The opinions and conclusion expressed here are intended to open the discussion in the field the importance of which is until now overshadowed by that given to purely technological aspects.

Openness to civil society: The challenges for the TSOs

International Nuclear Information System (INIS)

Petitfrere, M.; Rollinger, F.

2007-01-01

Society's concerns have led to changes in the legal framework towards a greater requirement for public information and participation in decision-making processes. International organisations such as the OECD/NEA and the IAEA have also made similar changes. What changes are necessary to the way TSOs work to make space for a fourth player - the population - in controlling radiological and nuclear risk? Society's participation varies from access to existing information to a desire to participate in expert assessments in a pluralistic assessment process. IRSN has made openness to civil society one of its four strategic priorities, and a dedicated team is responsible for carrying out actions in consultation with players from civil society, including the local information committees (CLIs). These actions lie at the heart of IRSN's strategy, because it is only by developing experimental expert assessment processes involving parts of civil society that both sides can learn from one another. Two pluralistic expert groups have been set up on radiological protection, and their innovative method of operation is worth highlighting. Another participative action is the development jointly with the CLIs in the Loire basin of methods of collecting environmental monitoring data. Finally, to accompany and promote this new approach internally, an internal network dedicated to stakeholder involvement has been set up. IRSN also intends to take advantage of existing experiences elsewhere. These moves towards joint expert assessment are an inevitable development that demands a real change of culture on the part of all players, putting technical issues as part of a broader process of evaluation and decision-making. Actually, they form part of a sustainable development approach. (author)

Energy the enabler, in our changing world

International Nuclear Information System (INIS)

Koomanoff, F.A.

1992-01-01

Historical industrial and social development made possible by energy technologies throughout the world serves as a paradigm for looking into the future. Energy usage is directly responsible for productivity. World population is increasing rapidly necessitating still more energy. The number of college students (a measure of new ideas and demands) has also increased rapidly. The U.S. has led in energy usage and the resultant growth in transportation and communication but changes are occurring. Urbanization - another effect of energy - shows the majority of high density populations now are in developing countries. Societies are changing from single nation states to interdependent loosely-knit larger socio-economic-environmental areas - Economic Communities. Successful technology must now engage producers, users, governments, as well as communities of interest. Political management systems must recognize these changes to permit the continued development of energy technologies. Looking toward the 21st Century and our continued development in a changing world necessitates recognition of the need for a systems orientation, interdisciplinary approach to find multi-answers to problems. All must participate in the decision making process - looking for solutions (rather than identification of problems) learning together and from each other - and most importantly, managing conflict before it manages us.

The response of southern California ecosystems to Younger Dryas-like rapid climate change: Comparison of glacial terminations 1 and 5.

Heusser, L. E.; Hendy, I. L.

2015-12-01

The Younger Dryas is a well-known rapid climatic cooling that interrupted the Marine Isotope Stage (MIS) 1-2 deglacial warming of Termination 1. This cool event has been associated with ice sheet readvance, meridional overturning, circulation changes, and southward movement of the Intertropical Convergence Zone. In Southern California, the Younger Dryas has been associated with cooler SST, low marine productivity, a well-ventilated oxygen minimum zone, and a wetter climate. Similar rapid cooling events have been found at other terminations including Termination 5 at the MIS 11-12 deglaciation (~425 Ka) identified by ice rafting events in the North Atlantic. Here we present new pollen census data from a unique suite of cores taken from the sub-oxic sediments of Santa Barbara Basin (MV0508-15JC, MV0805-20JC, MV0508-33JC, 29JC and 21JC). These short cores, collected on a truncated anticline within SBB, provide the opportunity to examine the response of southern California terrestrial and marine ecosystems to rapid climate change during the MIS 11-12 deglaciation (Termination 5), which is identified by a bioturbated interval within a sequence of laminated sediments. During Termination 1, changes in Southern California precipitation are reflected in pollen- based reconstructions Southern California vegetation. The high precipitation of glacial montane-coniferous assemblages of pine (Pinus) and Juniper (Juniperus/Calocedrus) transitions into interglacial drought, as expresssed by arid oak (Quercus)/chaparral vegetation. The Younger Dryas interrupts the transition as a high-amplitude pulse in pine associated with increased Gramineae (grass). Termination 5 differs, as the high precipitation of glacial montane-coniferous assemblages do not transition into arid oak/chaparral vegetation. However, a Younger Dryas-like rapid climate event was associated with increased pine and grass.

K-pop in Korea: How the Pop Music Industry is Changing a Post-Developmental Society

Directory of Open Access Journals (Sweden)

Ingyu Oh

2013-12-01

Full Text Available Korean popular songs, or kayo, are evolving from a musical genre created and performed only by Koreans into K-pop, a global musical genre produced and enjoyed by Koreans and those of other nationalities. This new development has revolutionized the perception of the popular music industry in Korea’s post-developmental society, as Korean children dream of becoming K-pop idols rather than entering traditionally esteemed careers in politics, medicine, or academia. The Korean government is also actively promoting Hallyu and K-pop, as though they constitute new export industries that could feed the entire nation in the twenty-first century. While the K-pop revolution has a lot to do with YouTube and other digital means of distributing music on a global scale, Korean television stations are now eager to tap into the booming market by showcasing live K-pop auditions in order to circumvent declining television loyalty among K-pop fans, who prefer watching music videos on YouTube. K-pop in Korea therefore illustrates three important aspects of social change: changes in social perceptions of the popular music industry, massive government support, and television stations actively recruiting new K-pop stars. All three aspects of social change reinforce one another and fuel the aspirations of young Koreans to become the next K-pop idols.

Full Text Available Several months in 2013 and 2014 have been a hardly predictable time in Ukraine, and the situation is still far from being stable. This made the editorial team of TCPHEE based in Ukraine postpone publishing consecutive issues. However, while the situation still requires practical steps, many aspects including those related to public health require analysis and debate. Thus we invite opinion pieces and studies addressing all different spheres of how public health should function under changing social circumstances. There might be a wide range of such related topics. The most obvious ones are those linked to changing living conditions. Many studies have been undertaken and published with regard to health threats to refugees, people involved in natural or technical disasters (Noji, 2005. Along with environmental health threats, there might be mental health disturbances (World Health Organization, 1992 resulting from long-term strain, losses et cetera. Another important focus is related to changes in health services provision. Crimea, which is a former Ukrainian territory now occupied by the Russian Federation, was among those in Ukraine highly affected with HIV (Dehne, Khodakevich, Hamers, & Schwartlander, 1999. This was responded by several NGOs actively providing harm reduction services to high-risk groups along with methadone substitution therapy to opiate users and antiretroviral medicines to those HIV-infected (Curtis, 2010. However, there are news reports that Russia is going to stop provision of methadone (kommersant.ru, 2014. As opiate substitution programs have been shown an effective approach towards preventing HIV transmission among people who inject drugs (MacArthur et al., 2012, such change in public health policies might affect not only most at risk populations but their partners and population as a whole as well resulting in a rapid spread of HIV. Yet another related topic is that of how health services can be organized at times of

Anthropology, social change and the reconstruction of South African society1

Full Text Available In this article it is argued that, since the abuse of anthropology in the colonial and apartheid eras, the responsive relationship between anthropology and society has been re-emphasised. In the reconstruction of South African society, therefore, anthropologists will not be allowed the luxury of evading their social responsibility. In their re-invention of anthropology as a humane science, and the reiteration of their commitment to accountability and relevance, these scientists ought to build their discipline upon the investigation of the major consequences of differential power and inequality. This could be helpful in creating new forms of co-existence in South Africa

Renal denervation (RDN) was reported as a novel exciting treatment for resistant hypertension in 2009. An initial randomized trial supported its efficacy and the technique gained rapid acceptance across the globe. However, a subsequent large blinded, sham arm randomized trial conducted in the USA (to gain Food and Drug Administration approval) failed to achieve its primary efficacy end point in reducing office blood pressure at 6 months. Published in 2014 this trial received both widespread praise and criticism. RDN has effectively stopped out with clinical trials pending further evidence. This joint consensus document representing the European Society of Hypertension and the Cardiovascular and Radiological Society of Europe attempts to distill the current evidence and provide future direction and guidance.

Health Systems Research in a Complex and Rapidly Changing Context: Ethical Implications of Major Health Systems Change at Scale.

Science.gov (United States)

MacGregor, Hayley; Bloom, Gerald

2016-12-01

This paper discusses health policy and systems research in complex and rapidly changing contexts. It focuses on ethical issues at stake for researchers working with government policy makers to provide evidence to inform major health systems change at scale, particularly when the dynamic nature of the context and ongoing challenges to the health system can result in unpredictable outcomes. We focus on situations where 'country ownership' of HSR is relatively well established and where there is significant involvement of local researchers and close ties and relationships with policy makers are often present. We frame our discussion around two country case studies with which we are familiar, namely China and South Africa and discuss the implications for conducting 'embedded' research. We suggest that reflexivity is an important concept for health system researchers who need to think carefully about positionality and their normative stance and to use such reflection to ensure that they can negotiate to retain autonomy, whilst also contributing evidence for health system change. A research process informed by the notion of reflexive practice and iterative learning will require a longitudinal review at key points in the research timeline. Such review should include the convening of a deliberative process and should involve a range of stakeholders, including those most likely to be affected by the intended and unintended consequences of change. © 2016 The Authors Developing World Bioethics Published by John Wiley & Sons Ltd.

Royal Society Scientific Meeting: Extracellular vesicles in the tumour microenvironment.

Cancer cells do not grow as an isolated homogeneous mass; tumours are, in fact, complex and heterogeneous collections of cancer and surrounding stromal cells, collectively termed the tumour microenvironment. The interaction between cancer cells and stromal cells in the tumour microenvironment has emerged as a key concept in the regulation of cancer progression. Understanding the intercellular dialogue in the tumour microenvironment is therefore an important goal. One aspect of this dialogue that has not been appreciated until recently is the role of extracellular vesicles (EVs). EVs are small vesicles released by cells under both normal and pathological conditions; they can transfer biological molecules between cells leading to changes in phenotype. EVs have emerged as important regulators of biological processes and can be dysregulated in diseases such as cancer; rapidly growing interest in their biology and therapeutic potential led to the Royal Society hosting a Scientific Meeting to explore the roles of EVs in the tumour microenvironment. This cross-disciplinary meeting explored examples of how aberrant crosstalk between tumour and stromal cells can promote cancer progression, and how such signalling can be targeted for diagnostic, prognostic and therapeutic benefit. In this review, and the special edition of Philosophical Transactions of the Royal Society B that follows, we will provide an overview of the content and outcomes of this exciting meeting.This article is part of the discussion meeting issue 'Extracellular vesicles and the tumour microenvironment'. © 2017 The Author(s).

Drylands represent our planet's largest terrestrial biome, making up over 35% of Earth's land surface. In the context of this vast areal extent, it is no surprise that recent research suggests dryland inter-annual variability and responses to change have the potential to drive biogeochemical cycles and climate at the global-scale. Further, the data we do have suggest drylands can respond rapidly and non-linearly to change. Nevertheless, our understanding of the cross-system consistency of and mechanisms behind dryland responses to a changed environment remains relatively poor. This poor understanding hinders not only our larger understanding of terrestrial ecosystem function, but also our capacity to forecast future global biogeochemical cycles and climate. Here we present data from a series of Colorado Plateau manipulation experiments - including climate, land use, and nitrogen deposition manipulations - to explore how vascular plants, microbial communities, and biological soil crusts (a community of mosses, lichens, and/or cyanobacteria living in the interspace among vascular plants in arid and semiarid ecosystems worldwide) respond to a host of environmental changes. These responses include not only assessments of community composition, but of their function as well. We will explore photosynthesis, net soil CO2 exchange, soil carbon stocks and chemistry, albedo, and nutrient cycling. The experiments were begun with independent questions and cover a range of environmental change drivers and scientific approaches, but together offer a relatively holistic picture of how some drylands can change their structure and function in response to change. In particular, the data show very high ecosystem vulnerability to particular drivers, but surprising resilience to others, suggesting a multi-faceted response of these diverse systems.

Full Text Available In an era witnessing the rapid development of information technology, mobile devices have brought revolutionary changes to learning. A single conventional media platform is not enough for the various mobile devices. Technology-enriched educational environments supported by different devices are important research issues nowadays. To capture the rapid growth of mobile users in Chinese societies, OpenCourseWare (OCW needs to move their learning models toward the mobile sphere. Therefore, this study reports the three years of empirical experience in implementing the upgraded National Tsing Hua University OCW platform and analyzes how users access the platform with various devices. The results indicate a responsive web design and cloud-computing provide great accessibility to meet the diversity of various mobile devices from Chinese users throughout the world, including 466,429 visits with 264 different mobile devices from 146 territories. Moreover, the proposed solutions make the workflow of OCW production more efficient. The study further discussed the importance of both tablets and smartphones. Moreover, to expand the reach of open educational resources (OER in Chinese societies, the critical issues of fair use and sustainability of OER should be of concern. The findings of the study provide valuable references for web engineers and educators to explore cross-device online learning using PCs and mobile devices.

Social Value Orientation and Capitalism in Societies

Shahrier, Shibly; Kakinaka, Makoto

2016-01-01

Cooperation and competition are core issues in various fields, since they are claimed to affect the evolution of human societies and ecological organizations. A long-standing debate has existed on how social behaviors and preferences are shaped with culture. Considering the economic environment as part of culture, this study examines whether the ongoing modernization of competitive societies, called “capitalism,” affects the evolution of people’s social preferences and behaviors. To test this argument, we implemented field experiments of social value orientation and surveys with 1002 respondents for three different areas of Bangladesh: (i) rural, (ii) transitional and (iii) capitalistic societies. The main result reveals that with the evolution from rural to capitalistic societies, people are likely to be less prosocial and more likely to be competitive. In a transitional society, there is a considerable proportion of “unidentified” people, neither proself nor prosocial, implying the potential existence of unstable states during a transformation period from rural to capitalistic societies. We also find that people become more proself with increasing age, education and number of children. These results suggest that important environmental, climate change or sustainability problems, which require cooperation rather than competition, will pose more danger as societies become capitalistic.

Full Text Available Introduction: Transverse deficiency of the maxilla is a common clinical problem in orthodontics and dentofacial orthopedics. Transverse maxillary deficiency, isolated or associated with other dentofacial deformities, results in esthetic and functional impairment giving rise to several clinical manifestations such as asymmetrical facial growth, positional and functional mandibular deviations, altered dentofacial esthetics, adverse periodontal responses, unstable dental tipping, and other functional problems. Orthopedic maxillary expansion is the preferred treatment approach to increase the maxillary transverse dimension in young patients by splitting of the mid palatal suture. This orthopedic procedure has lately been subject of renewed interest in orthodontic treatment mechanics because of its potential for increasing arch perimeter to alleviate crowding in the maxillary arch without adversely affecting facial profile. Hence, the present investigation was conducted to establish a correlation between transverse expansion and changes in the arch perimeter, arch width and arch length. Methods: For this purpose, 10 subjects (five males, five females were selected who had been treated by rapid maxillary expansion (RME using hyrax rapid palatal expander followed by fixed mechanotherapy (PEA. Pretreatment (T1, postexpansion (T2, and posttreatment (T3 dental models were compared for dental changes brought about by RME treatment and its stability at the end of fixed mechanotherapy. After model measurements were made, the changes between T1-T2, T2-T3 and T1-T3 were determined for each patient. The mean difference between T1-T2, T2-T3 and T1-T3 were compared to assess the effects of RME on dental arch measurements. Results are expressed as mean ± standard deviation and are compared by repeated measures analysis of variance followed by a post-hoc test. Arch perimeter changes are correlated with changes in arch widths at the canine, premolar and molar

To isolate a bacterial strain capable of biotransforming ferulic acid, a major component of lignin, into vanillin and vanillic acid by a rapid colorimetric screening method. For the production of vanillin, a natural aroma compound, we attempted to isolate a potential strain using a simple screening method based on pH change resulting from the degradation of ferulic acid. The strain Pseudomonas sp. AZ10 UPM exhibited a significant result because of colour changes observed on the assay plate on day 1 with a high intensity of yellow colour. The biotransformation of ferulic acid into vanillic acid by the AZ10 strain provided the yield (Yp/s ) and productivity (Pr ) of 1·08 mg mg(-1) and 53·1 mg L(-1) h(-1) , respectively. In fact, new investigations regarding lignin degradation revealed that the strain was not able to produce vanillin and vanillic acid directly from lignin; however, partially digested lignin by mixed enzymatic treatment allowed the strain to produce 30·7 mg l(-1) and 1·94 mg l(-1) of vanillic acid and biovanillin, respectively. (i) The rapid colorimetric screening method allowed the isolation of a biovanillin producer using ferulic acid as the sole carbon source. (ii) Enzymatic treatment partially digested lignin, which could then be utilized by the strain to produce biovanillin and vanillic acid. To the best of our knowledge, this is the first study reporting the use of a rapid colorimetric screening method for bacterial strains producing vanillin and vanillic acid from ferulic acid. © 2013 The Society for Applied Microbiology.

Rapid characterisation of vegetation structure to predict refugia and climate change impacts across a global biodiversity hotspot.

Directory of Open Access Journals (Sweden)

Antonius G T Schut

Full Text Available Identification of refugia is an increasingly important adaptation strategy in conservation planning under rapid anthropogenic climate change. Granite outcrops (GOs provide extraordinary diversity, including a wide range of taxa, vegetation types and habitats in the Southwest Australian Floristic Region (SWAFR. However, poor characterization of GOs limits the capacity of conservation planning for refugia under climate change. A novel means for the rapid identification of potential refugia is presented, based on the assessment of local-scale environment and vegetation structure in a wider region. This approach was tested on GOs across the SWAFR. Airborne discrete return Light Detection And Ranging (LiDAR data and Red Green and Blue (RGB imagery were acquired. Vertical vegetation profiles were used to derive 54 structural classes. Structural vegetation types were described in three areas for supervised classification of a further 13 GOs across the region. Habitat descriptions based on 494 vegetation plots on and around these GOs were used to quantify relationships between environmental variables, ground cover and canopy height. The vegetation surrounding GOs is strongly related to structural vegetation types (Kappa = 0.8 and to its spatial context. Water gaining sites around GOs are characterized by taller and denser vegetation in all areas. The strong relationship between rainfall, soil-depth, and vegetation structure (R(2 of 0.8-0.9 allowed comparisons of vegetation structure between current and future climate. Significant shifts in vegetation structural types were predicted and mapped for future climates. Water gaining areas below granite outcrops were identified as important putative refugia. A reduction in rainfall may be offset by the occurrence of deeper soil elsewhere on the outcrop. However, climate change interactions with fire and water table declines may render our conclusions conservative. The LiDAR-based mapping approach presented

Green, Martin S; Guerra, Peter G; Krahn, Andrew D

2011-01-01

The last guidelines on training for adult cardiac electrophysiology (EP) were published by the Canadian Cardiovascular Society in 1996. Since then, substantial changes in the knowledge and practice of EP have mandated a review of the previous guidelines by the Canadian Heart Rhythm Society, an affiliate of the Canadian Cardiovascular Society. Novel tools and techniques also now allow electrophysiologists to map and ablate increasingly complex arrhythmias previously managed with pharmacologic or device therapy. Furthermore, no formal attempt had previously been made to standardize EP training across the country. The 2010 Canadian Cardiovascular Society/Canadian Heart Rhythm Society Training Standards and Maintenance of Competency in Adult Clinical Cardiac Electrophysiology represent a consensus arrived at by panel members from both societies, as well as EP program directors across Canada and other select contributors. In describing program requirements, the technical and cognitive skills that must be acquired to meet training standards, as well as the minimum number of procedures needed in order to acquire these skills, the new guidelines provide EP program directors and committee members with a template to develop an appropriate curriculum for EP training for cardiology fellows here in Canada.

Innovation in regulation of rapidly changing health markets.

Bloom, Gerald; Henson, Spencer; Peters, David H

2014-06-24

The rapid evolution and spread of health markets across low and middle-income countries (LMICs) has contributed to a significant increase in the availability of health-related goods and services around the world. The support institutions needed to regulate these markets have lagged behind, with regulatory systems that are weak and under-resourced. This paper explores the key issues associated with regulation of health markets in LMICs, and the different goals of regulation, namely quality and safety of care, value for money, social agreement over fair access and financing, and accountability. Licensing, price controls, and other traditional approaches to the regulation of markets for health products and services have played an important role, but they have been of questionable effectiveness in ensuring safety and efficacy at the point of the user in LMICs. The paper proposes a health market systems conceptual framework, using the value chain for the production, distribution and retail of health goods and services, to examine regulation of health markets in the LMIC context. We conclude by exploring the changing context going forwards, laying out implications for future heath market regulation. We argue that the case for new approaches to the regulation of markets for health products and services in LMICs is compelling. Although traditional "command and control" approaches will have a place in the toolkit of regulators, a broader bundle of approaches is needed that is adapted to the national and market-level context of particular LMICs. The implication is that it is not possible to apply standard or single interventions across countries, as approaches proven to work well in one context will not necessarily work well elsewhere.

Rapid, generalized adaptation to asynchronous audiovisual speech.

Science.gov (United States)

Van der Burg, Erik; Goodbourn, Patrick T

2015-04-07

The brain is adaptive. The speed of propagation through air, and of low-level sensory processing, differs markedly between auditory and visual stimuli; yet the brain can adapt to compensate for the resulting cross-modal delays. Studies investigating temporal recalibration to audiovisual speech have used prolonged adaptation procedures, suggesting that adaptation is sluggish. Here, we show that adaptation to asynchronous audiovisual speech occurs rapidly. Participants viewed a brief clip of an actor pronouncing a single syllable. The voice was either advanced or delayed relative to the corresponding lip movements, and participants were asked to make a synchrony judgement. Although we did not use an explicit adaptation procedure, we demonstrate rapid recalibration based on a single audiovisual event. We find that the point of subjective simultaneity on each trial is highly contingent upon the modality order of the preceding trial. We find compelling evidence that rapid recalibration generalizes across different stimuli, and different actors. Finally, we demonstrate that rapid recalibration occurs even when auditory and visual events clearly belong to different actors. These results suggest that rapid temporal recalibration to audiovisual speech is primarily mediated by basic temporal factors, rather than higher-order factors such as perceived simultaneity and source identity. © 2015 The Author(s) Published by the Royal Society.

The aims of this study were to quantitatively evaluate the changes in arch widths and buccolingual inclinations of the posterior teeth after asymmetric rapid maxillary expansion (ARME) and to compare the measurements between the crossbite and the noncrossbite sides with cone-beam computed tomography (CBCT). From our clinic archives, we selected the CBCT records of 30 patients with unilateral skeletal crossbite (13 boys, 14.2 ± 1.3 years old; 17 girls, 13.8 ± 1.3 years old) who underwent ARME treatment. A modified acrylic bonded rapid maxillary expansion appliance including an occlusal locking mechanism was used in all patients. CBCT records had been taken before ARME treatment and after a 3-month retention period. Fourteen angular and 80 linear measurements were taken for the maxilla and the mandible. Frontally clipped CBCT images were used for the evaluation. Paired sample and independent sample t tests were used for statistical comparisons. Comparisons of the before-treatment and after-retention measurements showed that the arch widths and buccolingual inclinations of the posterior teeth increased significantly on the crossbite side of the maxilla and on the noncrossbite side of the mandible (P ARME treatment, the crossbite side of the maxilla and the noncrossbite side of the mandible were more affected than were the opposite sides.

Some health aspects of high-energy society

Cook, E.

1975-01-01

The intensive use of inanimate energy in industrialized or high-energy society has subsidized research, development, and higher education and has brought about changes in nutrition and life-style that have led to great advances in public health and medicine. The emergence of high-energy society, however, has brought with it a new set of health problems, within which the direct effects of measurable pollution may turn out to be more easily dealt with than some of the indirect and hard-to-calculate consequences of high energy use. High-energy society is critically dependent on energy-intensive transport systems, and these systems in turn are dependent upon a continual supply of petroleum products. In the short-term, the aorta of any industrialized nation is its petroleum-supply network. In the longer run, high-energy society faces the depletion and exhaustion of all the nonrenewable resources on which it has fed. Even if technology provides adequate substitute energy systems, high-energy society may deteriorate socially from inability to cope with affluence

In the process of establishing our nuclear power programme, we have helped in establishing many facets of the present industrial infrastructure in the country and in improving the quality of the products of many companies, big and small. Nuclear Power Corporation and the other industrial units of Department of Atomic Energy (DAE) have the powerful R and D backup of Bhabha Atomic Research Centre and the other research centres of DAE. There is extra-ordinary multi-disciplinary research expertise and technological capability in BARC, whose full potential I came to realize for the first time during the development programme and the project execution of the Peaceful Explosion Experiment at Pokhran in 1974. This expertise and capability should enable us to advance rapidly in the nuclear technology field and also help India to rapid progress in tomorrow's knowledge society. But these require careful management of technology development in the coming decades. (author)

Spectroscopic sensitivity of real-time, rapidly induced phytochemical change in response to damage.

Couture, John J; Serbin, Shawn P; Townsend, Philip A

2013-04-01

An ecological consequence of plant-herbivore interactions is the phytochemical induction of defenses in response to insect damage. Here, we used reflectance spectroscopy to characterize the foliar induction profile of cardenolides in Asclepias syriaca in response to damage, tracked in vivo changes and examined the influence of multiple plant traits on cardenolide concentrations. Foliar cardenolide concentrations were measured at specific time points following damage to capture their induction profile. Partial least-squares regression (PLSR) modeling was employed to calibrate cardenolide concentrations to reflectance spectroscopy. In addition, subsets of plants were either repeatedly sampled to track in vivo changes or modified to reduce latex flow to damaged areas. Cardenolide concentrations and the induction profile of A. syriaca were well predicted using models derived from reflectance spectroscopy, and this held true for repeatedly sampled plants. Correlations between cardenolides and other foliar-related variables were weak or not significant. Plant modification for latex reduction inhibited an induced cardenolide response. Our findings show that reflectance spectroscopy can characterize rapid phytochemical changes in vivo. We used reflectance spectroscopy to identify the mechanisms behind the production of plant secondary metabolites, simultaneously characterizing multiple foliar constituents. In this case, cardenolide induction appears to be largely driven by enhanced latex delivery to leaves following damage. © 2013 The Authors. New Phytologist © 2013 New Phytologist Trust.

[Changing surgical therapy because of clinical studies?].

Schwenk, W; Haase, O; Müller, J M

2002-04-01

The randomised controlled clinical trial (RCT) is a powerful instrument to evaluate different therapeutic regimens. In a survey among 115 physicians visiting the 25th annual meeting of the Surgical Society of Berlin and Brandenburg, the RCT was judged to be very important when changes of therapeutic strategies are discussed. 90 % of all participants claimed to use data from RCTs in the clinical routine and 89 % would participate in such a trial. In official (e. g. discussions during coffee breaks at scientific meetings) or non-medical (e. g. non-scientific press or media) sources of information were assessed as irrelevant for decisions regarding therapeutic strategies. However, in contrast to this view laparoscopic cholecystectomy was introduced into clinical practice rapidly because patients informed by external (non-medical) sources preferred to be operated on with the "modern" technique. Clinical trials with a high level of evidence had no relevant influence on the rapid distribution of laparoscopic cholecystectomy. Controversial discussions concerning the extent of lymphadenectomy with gastric resection for carcinoma demonstrate that the value of excellent clinical RCTs is low if their results challenge a stable paradigma of the surgical scientific society. To allow a rational judgement, new surgical technologies should undergo a scientific gradual evaluation in agreement with the principles of evidence based medicine.

In Spain the transfer of nurse education to universities was accompanied by a shift towards a model of person-centred care. To explore whether the change in nurses' professional profile (from physician assistant to providers of person-centred care) was a response to changing needs in Spanish society. Qualitative study. Theoretical sampling and in-depth interviews using an inductive analytical approach. Four categories described the nursing profession in Spain prior to the introduction of university training: the era of medical assistants; technologisation of hospitals; personal care of the patient based on Christian values; professional socialisation differentiated by gender. Further analysis showed that these categories could be subsumed under a broader core category: the transfer of nurse education to universities as part of Spain's transition to democracy. The transfer of nurse education to universities was one of several changes occurring in Spanish society during the country's transition to democratic government. The redefined public health system required a highly skilled workforce, with improved employment rights being given to female health professionals, notably nurses. Copyright © 2017 Elsevier Ltd.

Net Ecosystem Exchange of CO2 with Rapidly Changing High Arctic Landscapes

Emmerton, C. A.

High Arctic landscapes are expansive and changing rapidly. However our understanding of their functional responses and potential to mitigate or enhance anthropogenic climate change is limited by few measurements. We collected eddy covariance measurements to quantify the net ecosystem exchange (NEE) of CO2 with polar semidesert and meadow wetland landscapes at the highest-latitude location measured to date (82°N). We coupled these rare data with ground and satellite vegetation production measurements (Normalized Difference Vegetation Index; NDVI) to evaluate the effectiveness of upscaling local to regional NEE. During the growing season, the dry polar semidesert landscape was a near zero sink of atmospheric CO2 (NEE: -0.3±13.5 g C m-2). A nearby meadow wetland accumulated over two magnitudes more carbon (NEE: -79.3±20.0 g C m-2) than the polar semidesert landscape, and was similar to meadow wetland NEE at much more southern latitudes. Polar semidesert NEE was most influenced by moisture, with wetter surface soils resulting in greater soil respiration and CO2 emissions. At the meadow wetland, soil heating enhanced plant growth, which in turn increased CO2 uptake. Our upscaling assessment found that polar semidesert NDVI measured on site was low (mean: 0.120-0.157) and similar to satellite measurements (mean: 0.155-0.163). However, weak plant growth resulted in poor satellite NDVI-NEE relationships and created challenges for remotely-detecting changes in the cycling of carbon on the polar semidesert landscape. The meadow wetland appeared more suitable to assess plant production and NEE via remote-sensing, however high Arctic wetland extent is constrained by topography to small areas that may be difficult to resolve with large satellite pixels. We predict that until summer precipitation and humidity increases substantially, climate-related changes of dry high Arctic landscapes may be restricted by poor soil moisture retention, and therefore have some inertia against

In scientific societies, as in other social fields, women's participation in decision making is lower than that of men. We describe the situation in SESPAS (Spanish Society of Public Health and Health Services Administration) where, despite representing a 40% of its members, very few women have been in positions in which decisions are taken or in those of professional recognition. The process of change implemented during recent years and some of the effects of the actions taken are presented. Making the existing inequalities known has generated debate and interest in the intervention. A gender and public health working group was set up. In the last two years more women have been promoted to more senior positions in SESPAS.

Our principal goal is to develop better, more far-looking tools to predict the cumulative effects of resource development, climate-change, and traditional land use. Here we use remote sensing, climate-change analyses, socio-economic analyses, and vegetation-change models to examine the cumulative effects of climate change, gas development, and reindeer herding on the Yamal Peninsula in northwest Siberia as part of the Northern Eurasia Earth Science Partnership Initiative (NEESPI). We find: 1. Direct (planned) impacts of industrial activities on the Yamal Peninsula are currently local and limited in extent, but this is changing rapidly as extensive gas fields are developed and land and sea transportation corridors are developed to get the gas to market. Indirect impacts of the development at Bovanenkovo, the largest gas field, exceed the direct impacts by a factor of three, and the total area of influence of the development on the reindeer pasturelands (e.g., area where migration routes and access to pasturelands is affected) exceeds the direct impacts by a factor of about 40. 2. The trend in land-surface temperatures has co-varied with the trend in sea-ice. Low sea ice in the preceding December-March period is correlated to warmer land temperature the following summer. The sea- ice trends in the Kara Sea-Yamal region are tied to variation in the North Atlantic Oscillation index. 4. Only a small greening response to warming has been detected on the Yamal in comparison with some other areas in the Arctic (e.g. Northern Alaska). The actual effects of climate-change on vegetation are currently hard to document at the ground level because of lack of baseline and long-term ground observations and difficulty of excluding reindeer in these studies. 5. There is high potential for extensive landscape effects due to unstable sandy soils, and extremely ice-rich permafrost near the surface on slopes. 6. Two different vegetation modeling approaches are being used to predict

The Marginal Ice Zone (MIZ) of the Arctic Ocean is changing rapidly due to a warming Arctic climate with commensurate reductions in sea ice extent and thickness. This Pan-Arctic review summarizes the main changes in the Arctic ocean-sea ice-atmosphere (OSA) interface, with implications for primary- and secondary producers in the ice and the underlying water column. Changes in the Arctic MIZ were interpreted for the period 1979-2010, based on best-fit regressions for each month. Trends of increasingly open water were statistically significant for each month, with quadratic fit for August-November, illustrating particularly strong seasonal feedbacks in sea-ice formation and decay. Geographic interpretations of physical and biological changes were based on comparison of regions with significant changes in sea ice: (1) The Pacific Sector of the Arctic Ocean including the Canada Basin and the Beaufort, Chukchi and East Siberian seas; (2) The Canadian Arctic Archipelago; (3) Baffin Bay and Hudson Bay; and (4) the Barents and Kara seas. Changes in ice conditions in the Barents sea/Kara sea region appear to be primarily forced by ocean heat fluxes during winter, whereas changes in the other sectors appear to be more summer-autumn related and primarily atmospherically forced. Effects of seasonal and regional changes in OSA-system with regard to increased open water were summarized for photosynthetically available radiation, nutrient delivery to the euphotic zone, primary production of ice algae and phytoplankton, ice-associated fauna and zooplankton, and gas exchange of CO2. Changes in the physical factors varied amongst regions, and showed direct effects on organisms linked to sea ice. Zooplankton species appear to be more flexible and likely able to adapt to variability in the onset of primary production. The major changes identified for the ice-associated ecosystem are with regard to production timing and abundance or biomass of ice flora and fauna, which are related to

In the past decade many areas of Peru have been undergoing extreme environmental, economic, and cultural change. In the highland hamlet of Chugurpampa, La Libertad, climate change has ruined harvests and led to frequent periods of migration to the coast in search of livelihood. This biocultural research examines how the changes could be affecting the growth of children who maintain residence in the highlands. Clinical records from the early 2000s were compared to those from the early 2010s. Charts were randomly selected to record anthropometric data, netting a sample of 75 children ages 0-60 months of age. Analysis of covariance was run to compare mean stature, weight, and BMI between cohorts. Percentage of children who fall below the -2 threshold for z-scores for height and weight were compared by age and cohort. A significant secular trend in growth was found, with children born more recently larger than those born a decade before. The effect is most notable in the first year of life, with the growth advantage attenuated by the age of 3 for height and age 4 for weight. While children were unlikely to be stunted from 0 to 3 years of age, 44% of the later cohort were stunted and 11% were underweight from 4 to 5 years of age. Three possible explanations for the rapid shift are entertained: more time spent on the coast during gestation and early childhood, which may attenuate the effect of hypoxia on child growth; dietary change; and increased use of biomedicine. © 2017 Wiley Periodicals, Inc.

Speaking engagements, serving as session chairs, and receiving awards at national meetings are essential stepping stones towards professional success for scientific researchers. Studies of gender parity in meetings of national scientific societies repeatedly uncover bias in speaker selection, engendering underrepresentation of women among featured presenters. To continue this dialogue, we analyzed membership data and annual conference programs of a large scientific society (>7000 members annually) in a male-rich ( 70% males), technology-oriented STEM subfield. We detected a pronounced skew towards males among invited keynote lecturers, plenary speakers, and recipients of the society's Senior Investigator award (15%, 13%, and 8% females, respectively). However, the proportion of females among Mid-Career and Young Investigator award recipients and oral session chairs resembled the current gender distribution of the general membership. Female members were more likely to present at the conferences and equally likely to apply and be accepted for oral presentations as their male counterparts. The gender of a session chair had no effect on the gender distribution of selected applicants. Interestingly, we identified several research subareas that were naturally enriched (i.e., not influenced by unequal selection of presenters) for either female or male participants, illustrating within a single subfield the gender divide along biology-technology line typical of all STEM disciplines. Two female-enriched topics experienced a rapid growth in popularity within the examined period, more than doubling the number of associated researchers. Collectively, these findings contribute to the contemporary discourse on gender in science and hopefully will propel positive changes within this and other societies.

Extreme Temperature Exceedances Change more Rapidly Under Future Warming in Regions of non-Gaussian Short Temperature Distribution Tails

Science.gov (United States)

Loikith, P. C.; Neelin, J. D.; Meyerson, J.

2017-12-01

Regions of shorter-than-Gaussian warm and cold side temperature distribution tails are shown to occur in spatially coherent patterns in the current climate. Under such conditions, warming may be manifested in more complex ways than if the underlying distribution were close to Gaussian. For example, under a uniform warm shift, the simplest prototype for future warming, a location with a short warm side tail would experience a greater increase in extreme warm exceedances compared to if the distribution were Gaussian. Similarly, for a location with a short cold side tail, a uniform warm shift would result in a rapid decrease in extreme cold exceedances. Both scenarios carry major societal and environmental implications including but not limited to negative impacts on human and ecosystem health, agriculture, and the economy. It is therefore important for climate models to be able to realistically reproduce short tails in simulations of historical climate in order to boost confidence in projections of future temperature extremes. Overall, climate models contributing to the fifth phase of the Coupled Model Intercomparison Project capture many of the principal observed regions of short tails. This suggests the underlying dynamics and physics occur on scales resolved by the models, and helps build confidence in model projections of extremes. Furthermore, most GCMs show more rapid changes in exceedances of extreme temperature thresholds in regions of short tails. Results therefore suggest that the shape of the tails of the underlying temperature distribution is an indicator of how rapidly a location will experience changes to extreme temperature occurrence under future warming.

At the same time, today's children live in crowded information space, which highlights the issue of formation of information culture of their bases from an early age and quality of development needed for successful self-realization in the information society. This leads to changes in the entire education system, in particular the training of future elementary school teachers. A retrospective analysis of the use of information and communication technologies in education confirms the occurrence of such technologies for the development of children, which at different times dreamed of teachers and psychologists. Analysis of practice of training future elementary school teachers shows insufficient level of awareness of modern ICT capabilities, which are mainly used to support the traditional educational process, not the implementation of new learning approaches.

The unprecedented aging of society is occurring rapidly Rather than a problem facing the future, this trend is already a reality in Japan. The discussion regarding the maintenance of the social environment surrounding medical care is important. Also important are the appropriate medical interventions for the diagnosis of various changes and conditions that are characteristic of the aging patient. However, it is extremely difficult to establish the border of morbid change if the brain-related change is normal. The main risk factor for the patient with dementia is aging itself. The neuroradiologist is an important source of precise imaging information as to what is normal and what is abnormal. (author)

Rapid Modulation of Aromatase Activity in the Vertebrate Brain

Directory of Open Access Journals (Sweden)

Thierry D. Charlier

2013-01-01

Full Text Available Numerous steroid hormones, including 17β-estradiol (E2, activate rapid and transient cellular, physiological, and behavioral changes in addition to their well-described genomic effects. Aromatase is the key-limiting enzyme in the production of estrogens, and the rapid modulation of this enzymatic activity could produce rapid changes in local E2 concentrations. The mechanisms that might mediate such rapid enzymatic changes are not fully understood but are currently under intense scrutiny. Recent studies in our laboratory indicate that brain aromatase activity is rapidly inhibited by an increase in intracellular calcium concentration resulting from potassium-induced depolarization or from the activation of glutamatergic receptors. Phosphorylating conditions also reduce aromatase activity within minutes, and this inhibition is blocked by the addition of multiple protein kinase inhibitors. This rapid modulation of aromatase activity by phosphorylating conditions is a general mechanism observed in different cell types and tissues derived from a variety of species, including human aromatase expressed in various cell lines. Phosphorylation processes affect aromatase itself and do not involve changes in aromatase protein concentration. The control of aromatase activity by multiple kinases suggests that several amino acids must be concomitantly phosphorylated to modify enzymatic activity but site-directed mutagenesis of several amino acids alone or in combination has not to date revealed the identity of the targeted residue(s. Altogether, the phosphorylation processes affecting aromatase activity provide a new general mechanism by which the concentration of estrogens can be rapidly altered in the brain.

Sedentism, social change, warfare, and the bow in the ancient Pueblo Southwest.

Reed, Paul F; Geib, Phil R

2013-01-01

In the ancient American Southwest, use of the bow developed relatively rapidly among Pueblo people by the fifth century AD. This new technology replaced the millennia-old atlatl and dart weaponry system. Roughly 150 years later in the AD 600s, Pueblo socioeconomic organization began to evolve rapidly, as many groups adopted a much more sedentary life. Multiple factors converged to allow this sedentary pattern to emerge, but the role of the bow in this process has not been fully explored. In this paper, we trace the development of the bow and discuss its role as sedentism emerged and social changes occurred in ancient Puebloan society from the fifth through seventh centuries AD.

Coevolution of nutrigenomics and society: ethical considerations.

Science.gov (United States)

Korthals, Michiel

2011-12-01

To optimize the coevolution of nutrigenomics and society (ie, the reciprocal stimulation of both developments), I analyzed chances for a fruitful match between normative concepts and strategies of both developments. Nutrigenomics embodies ≥ 3 normative concepts. First, food is exclusively interpreted in terms of disease prevention. Second, striving for health is interpreted as the quantification of risks and prevention of diseases through positive food-gene interactions. The third normative idea is that disease prevention by the minimization of risks is an individual's task. My thesis was that these concepts of nutrigenomics would not easily match with concepts of food and health of various food styles in Western societies, which, for instance, parents in the case of metabolic programming endorse and with a philosophical view of the relation between food, health, and the meaning of life. Next, I reflected on the nonsynchronized coevolution of nutrigenomics and society because of this mismatch and introduced the concept of the fair representation of food styles in nutrigenomic developments. To synchronize and optimize the coevolution of nutrigenomics and society, I propose that the research policy of nutrigenomics should change to a research partnership with society on the basis of fair representation.

Rapid Land Cover Map Updates Using Change Detection and Robust Random Forest Classifiers

Konrad J. Wessels

2016-10-01

Full Text Available The paper evaluated the Landsat Automated Land Cover Update Mapping (LALCUM system designed to rapidly update a land cover map to a desired nominal year using a pre-existing reference land cover map. The system uses the Iteratively Reweighted Multivariate Alteration Detection (IRMAD to identify areas of change and no change. The system then automatically generates large amounts of training samples (n > 1 million in the no-change areas as input to an optimized Random Forest classifier. Experiments were conducted in the KwaZulu-Natal Province of South Africa using a reference land cover map from 2008, a change mask between 2008 and 2011 and Landsat ETM+ data for 2011. The entire system took 9.5 h to process. We expected that the use of the change mask would improve classification accuracy by reducing the number of mislabeled training data caused by land cover change between 2008 and 2011. However, this was not the case due to exceptional robustness of Random Forest classifier to mislabeled training samples. The system achieved an overall accuracy of 65%–67% using 22 detailed classes and 72%–74% using 12 aggregated national classes. “Water”, “Plantations”, “Plantations—clearfelled”, “Orchards—trees”, “Sugarcane”, “Built-up/dense settlement”, “Cultivation—Irrigated” and “Forest (indigenous” had user’s accuracies above 70%. Other detailed classes (e.g., “Low density settlements”, “Mines and Quarries”, and “Cultivation, subsistence, drylands” which are required for operational, provincial-scale land use planning and are usually mapped using manual image interpretation, could not be mapped using Landsat spectral data alone. However, the system was able to map the 12 national classes, at a sufficiently high level of accuracy for national scale land cover monitoring. This update approach and the highly automated, scalable LALCUM system can improve the efficiency and update rate of regional land

The concept of thresholds shows important implications for environmental and resource management. Here we derived potential landscape thresholds which indicated abrupt changes in water quality or the dividing points between exceeding and failing to meet national surface water quality standards for a rapidly urbanizing city on the Eastern Coast in China. The analysis of landscape thresholds was based on regression models linking each of the seven water quality variables to each of the six landscape metrics for this coupled land-water system. We found substantial and accelerating urban sprawl at the suburban areas between 2000 and 2008, and detected significant nonlinear relations between water quality and landscape pattern. This research demonstrated that a simple modeling technique could provide insights on environmental thresholds to support more-informed decision making in land use, water environmental and resilience management. - Graphical abstract: Fig. Threshold models and resilience management for water quality. Display Omitted - Highlights: • Coupling urbanization and water environmental system. • Developing threshold models of the coupled land-water systems. • Nonlinear relations between water quality variables and landscape metrics. • Enhancing resilience management of coastal rapid urbanization. - We develop environmental threshold models and provide their implications on resilience management for a coupled land-water system with rapid urbanization.

Full Text Available Social evolution is a continuation of biological evolution. The difference is the presence of mind, language and thinking. Therefore, society can be viewed as a living and rational system. The engine of social evolution is knowledge. Development of society is determined bilaterally by objective and subjective factors. Objective factors determine the form of society, subjective – the content. Society has three subsystems: social consciousness, economics and governance. The changes which take place in society are quantitative (evolutionary and qualitative (revolutionary. The spiral of social evolution begins with a cultural revolution that consistently changes economic relations and the organization of society, leading to the emergence of civilization. Declining civilization is a prerequisite for the emergence of a new cultural revolution. From this point of view humanity today faces dramatic changes – the emergence of social self-consciousness and transition from a hierarchical social structure to a horizontal organization. The New World Order advocated by power and the financial elite is impossible to implement because it contradicts the principles of social evolution. Throughout human history, social evolution has been a theory of qualitative changes in social structure, aiming to discover the fundamental laws of the origin and development of humanity as a whole. Social evolution complements several basic research fields in human sciences like history, cultural evolution, anthropology, philosophy of history, social and developmental psychology, etc. The process of social evolution is very complicated and controversial. During the last two centuries, a dozen approaches, theories, concepts and paradigms have been trying to describe and explain how society works and evolves. Modern theories provide models clarifying the relationship between social structure, economy, technology, social values, etc. Nevertheless, social evolution remains

The origins of the consumer society: socio-philosophical analysis

O. O. Serdyuk

2014-05-01

Full Text Available This article investigates the prerequisites of the consumer society and the theories of «consumer revolution». According to these theories, the formation of consumer society began long before the industrial age, consumerism revolution is represented by a consequence of economic development of production and markets at the end of the eighteenth century, which contributed to a significant expansion of public participation in the consumption and the changing of role of things in social life. It is shown that in this time consumption becomes more demonstrative, the status of things, is changing which is beginning to be appreciated not its durability, utility, and compliance with the latest fashion trends and prestige. The author believes that in the eighteenth century consumption only began to emerge and was not spread to the in public general, was part of a private rather than public life, being limited practice of general population. Concepts of consumer revolution are retrospective theories aimed to study of the origins of the trends of development of the society acquired relevance in our time. The author concludes that in traditional and premodern societies consumption due to objective reasons could not be widespread.

Water Quality Changes during Rapid Urbanization in the Shenzhen River Catchment: An Integrated View of Socio-Economic and Infrastructure Development

Directory of Open Access Journals (Sweden)

2014-10-01

Full Text Available Surface water quality deterioration is a serious problem in many rapidly urbanizing catchments in developing countries. There is currently a lack of studies that quantify water quality variation (deterioration or otherwise due to both socio-economic and infrastructure development in a catchment. This paper investigates the causes of water quality changes over the rapid urbanization period of 1985–2009 in the Shenzhen River catchment, China and examines the changes in relation to infrastructure development and socio-economic policies. The results indicate that the water quality deteriorated rapidly during the earlier urbanization stages before gradually improving over recent years, and that rapid increases in domestic discharge were the major causes of water quality deterioration. Although construction of additional wastewater infrastructure can significantly improve water quality, it was unable to dispose all of the wastewater in the catchment. However, it was found that socio-economic measures can significantly improve water quality by decreasing pollutant load per gross regional production (GRP or increasing labor productivity. Our findings suggest that sustainable development during urbanization is possible, provided that: (1 the wastewater infrastructure should be constructed timely and revitalized regularly in line with urbanization, and wastewater treatment facilities should be upgraded to improve their nitrogen and phosphorus removal efficiencies; (2 administrative regulation policies, economic incentives and financial policies should be implemented to encourage industries to prevent or reduce the pollution at the source; (3 the environmental awareness and education level of local population should be increased; (4 planners from various sectors should consult each other and adapt an integrated planning approach for socio-economic and wastewater infrastructure development.

The focus of women in The American Fertility Society.

Haseltine, F P; Wentz, A C

1984-09-01

This article reports survey responses from 71 female members of the American Fertility Society during the Society's 1984 annual meeting. Survey questions concern 1) demographic factors such as rank, degree, title, address, and number of children, 2) field of specialization and research interests, and 3) what the Society can do for its meeting participants. The typical respondent is a physician living in the Eastern United States and employed as an assistant professor in an academic setting. In vitro fertilization is the greatest area of interest, followed by general practice, endocrine and male infertility, contraception, and fertility surgery. Survey responses show that women are interested in 1) networking, 2) increased visibility at professional meetings, 3) information about research possibilities and grants, 4) child care provision at Society meetings, and 5) more basic science and physiology oriented presentions in the program. In response to networking interests, the Society will make available information from the surveyed members. Since 16% of respondents have a PH.D., and 77% are employed in academics, the Society should consider more basic presentations. The need for day care indicates changes in Society membership. The Society plans to conduct similar surveys on a regular basis.

Global changes are causing broad-scale shifts in vegetation communities worldwide, including coastal habitats where the borders between mangroves and salt marsh are in flux. Coastal habitats provide numerous ecosystem services of high economic value, but the consequences of variation in mangrove cover are poorly known. We experimentally manipulated mangrove cover in large plots to test a set of linked hypotheses regarding the effects of changes in mangrove cover. We found that changes in mangrove cover had strong effects on microclimate, plant community, sediment accretion, soil organic content, and bird abundance within 2 yr. At higher mangrove cover, wind speed declined and light interception by vegetation increased. Air and soil temperatures had hump-shaped relationships with mangrove cover. The cover of salt marsh plants decreased at higher mangrove cover. Wrack cover, the distance that wrack was distributed from the water's edge, and sediment accretion decreased at higher mangrove cover. Soil organic content increased with mangrove cover. Wading bird abundance decreased at higher mangrove cover. Many of these relationships were non-linear, with the greatest effects when mangrove cover varied from zero to intermediate values, and lesser effects when mangrove cover varied from intermediate to high values. Temporal and spatial variation in measured variables often peaked at intermediate mangrove cover, with ecological consequences that are largely unexplored. Because different processes varied in different ways with mangrove cover, the "optimum" cover of mangroves from a societal point of view will depend on which ecosystem services are most desired. © 2016 by the Ecological Society of America.

Nanotechnology is a rapidly developing discipline with enormous promise for consumers and patients. Currently, it is entering an inflection point in its growth phase--both in the number and diversity of products developed or soon to be available for society and medicine. It is no surprise that a vast number of patents have been issued for nanotechnology in the cosmetics arena as a means of enhancing topical delivery of a broad range of over-the-counter products. In fact, the skin is the first point of contact for a whole host of nanomaterials, ranging from topical preparations, articles of clothing and household products, to sporting goods and industrial manufactured goods. Very little is known about the safety aspects of the nano-engineered materials that are being released in the environment, as well as those in consumer and healthcare products.

Technology, risk and participation: The attitude of society towards insecurity

International Nuclear Information System (INIS)

Wynne, B.

1983-01-01

The way society deals with risks in connection with society's judgement and decision on technological developments is discussed. If technology is a social phenomenon one must attribute more importance to unknown changes of social values resulting from these decisions and to unforeseen physical effects. One should therefore shift from fact analysis as a basis of decisions to a critical analysis of the creditworthyness, responsibility and degree to which the views of the decision-making institutions and elites are understood by society.

The role of obstetrics and gynecology national societies during natural disasters.

Lalonde, André; Adrien, Lauré

2015-07-01

When a natural disaster occurs, such as an earthquake, floods, or a tsunami, the international response is quick. However, there is no organized strategy in place to address obstetric and gynecological (ob/gyn) emergencies. International organizations and national ob/gyn societies do not have an organized plan and rely on the good will of volunteers. Too often, local specialists are ignored and are not involved in the response. The massive earthquake in Haiti in 2010 exemplifies the lack of coordinated response involving national organizations following the disaster. The Society of Obstetricians and Gynaecologists of Canada (SOGC) engaged rapidly with Haitian colleagues in response to the obstetric and gynecological emergencies. An active strategy is proposed.

Dickens, M J; Balthazart, J; Cornil, C A

2012-10-01

Neural production of 17β-oestradiol via aromatisation of testosterone may play a critical role in rapid, nongenomic regulation of physiological and behavioural processes. In brain nuclei implicated in the control of sexual behaviour, sexual or stressfull stimuli induce, respectively, a rapid inhibition or increase in preoptic aromatase activity (AA). In the present study, we tested quail that were either nonstressed or acutely stressed (15 min of restraint) immediately before sexual interaction (5 min) with stressed or nonstressed partners. We measured nuclei-specific AA changes, corresponding behavioural output, fertilisation rates and corticosterone (CORT) concentrations. In males, sexual interaction rapidly reversed stress-induced increases of AA in the medial preoptic nucleus (POM). This time scale (sexual stimuli on POM AA may actively preserve sexual behaviour despite stress exposure. We also found distinct sex differences in contextual physiological responses: males did not show any effect of partner status, whereas females responded to both their stress exposure and the male partner's stress exposure at the level of circulating CORT and AA. In addition, fertilisation rates and female CORT correlated with the male partner's exhibition of sexually aggressive behaviour, suggesting that female perception of the male can affect their physiology as much as direct stress. Overall, male reproduction appears relatively simple: sexual stimuli, irrespective of stress, drives major neural changes including rapid reversal of stress-induced changes of AA. By contrast, female reproduction appears more nuanced and context specific, with subjects responding physiologically and behaviourally to stress, the male partner's stress exposure, and female-directed male behaviour. © 2012 The Authors.

The Accreditation Examination Committee of engineering education was established in 1997 in the Japan Engineering Education Society, and the International Universal Engineer Review Board was established in the Japan Engineering Education Society and the Japan Engineering Society in 1998. A series of the activities was connected to the establishment of 'Japan Accreditation Board for Engineering Education' (JABEE). To adapt to the movements, the Educational Program Review Board in the Engineering was installed in 1997 mainly composed of directors of engineering departments of 8 national universities. This Board arranges the contents of engineering education in the orders as follows, and studies on this base are being promoted. (1) Static (engineering basic knowledge, engineering special knowledge, expert skill), (2) Dynamic (search, design, analysis and application, synthesis and comprehension), (3) Mental 1 (External: Negotiation ability, persuasion linguistic ability, language ability, positiveness cooperativeness, etc.), (4) Mental 2 (world view, engineering ethics, sense of responsibility, self-development, economy sense, international sense, etc.).

Kakisawa, Hideki; Minagawa, Kazumi; Halada, Kohmei

2003-01-01

The relationship between consolidating temperature and the tensile behavior of iron alloy produced from Fe-Cu rapidly solidified powder is investigated. Fe-Cu powder fabricated by high-pressure water atomization was consolidated by heavy rolling at 873-1273 K. Microstructural changes were observed and tensile behavior was examined. Tensile behavior varies as the consolidating temperature changes, and these temperature-dependent differences depend on the morphology of the microstructure on the order of micrometers. The sample consolidated at 873 K shows a good strength/elongation balance because the powder microstructure and primary powder boundaries are maintained. The samples consolidated at the higher temperatures have a microstructure of recrystallized grains, and these recrystallized samples show the conventional relationship between tensile behavior and grain size in ordinal bulk materials

Habit Discontinuity, Self-Activation, and the Diminishing Influence of Context Change: Evidence from the UK Understanding Society Survey.

Gregory Owen Thomas

Full Text Available Repeated behaviours in stable contexts can become automatic habits. Habits are resistant to information-based techniques to change behaviour, but are contextually cued, so a change in behaviour context (e.g., location weakens habit strength and can facilitate greater consideration of the behaviour. This idea was demonstrated in previous work, whereby people with strong environmental attitudes have lower car use, but only after recently moving home. We examine the habit discontinuity hypothesis by analysing the Understanding Society dataset with 18,053 individuals representative of the UK population, measuring time since moving home, travel mode to work, and strength of environmental attitudes. Results support previous findings where car use is significantly lower among those with stronger environmental views (but only after recently moving home, and in addition, demonstrate a trend where this effects decays as the time since moving home increases. We discuss results in light of moving into a new home being a potential 'window of opportunity' to promote pro-environmental behaviours.

Rapid Environmental Change Drives Increased Land Use by an Arctic Marine Predator.

Todd C Atwood

Full Text Available In the Arctic Ocean's southern Beaufort Sea (SB, the length of the sea ice melt season (i.e., period between the onset of sea ice break-up in summer and freeze-up in fall has increased substantially since the late 1990s. Historically, polar bears (Ursus maritimus of the SB have mostly remained on the sea ice year-round (except for those that came ashore to den, but recent changes in the extent and phenology of sea ice habitat have coincided with evidence that use of terrestrial habitat is increasing. We characterized the spatial behavior of polar bears spending summer and fall on land along Alaska's north coast to better understand the nexus between rapid environmental change and increased use of terrestrial habitat. We found that the percentage of radiocollared adult females from the SB subpopulation coming ashore has tripled over 15 years. Moreover, we detected trends of earlier arrival on shore, increased length of stay, and later departure back to sea ice, all of which were related to declines in the availability of sea ice habitat over the continental shelf and changes to sea ice phenology. Since the late 1990s, the mean duration of the open-water season in the SB increased by 36 days, and the mean length of stay on shore increased by 31 days. While on shore, the distribution of polar bears was influenced by the availability of scavenge subsidies in the form of subsistence-harvested bowhead whale (Balaena mysticetus remains aggregated at sites along the coast. The declining spatio-temporal availability of sea ice habitat and increased availability of human-provisioned resources are likely to result in increased use of land. Increased residency on land is cause for concern given that, while there, bears may be exposed to a greater array of risk factors including those associated with increased human activities.

Rapid changes in ice core gas records - Part 1: On the accuracy of methane synchronisation of ice cores

Science.gov (United States)

Köhler, P.

2010-08-01

Methane synchronisation is a concept to align ice core records during rapid climate changes of the Dansgaard/Oeschger (D/O) events onto a common age scale. However, atmospheric gases are recorded in ice cores with a log-normal-shaped age distribution probability density function, whose exact shape depends mainly on the accumulation rate on the drilling site. This age distribution effectively shifts the mid-transition points of rapid changes in CH4 measured in situ in ice by about 58% of the width of the age distribution with respect to the atmospheric signal. A minimum dating uncertainty, or artefact, in the CH4 synchronisation is therefore embedded in the concept itself, which was not accounted for in previous error estimates. This synchronisation artefact between Greenland and Antarctic ice cores is for GRIP and Byrd less than 40 years, well within the dating uncertainty of CH4, and therefore does not calls the overall concept of the bipolar seesaw into question. However, if the EPICA Dome C ice core is aligned via CH4 to NGRIP this synchronisation artefact is in the most recent unified ice core age scale (Lemieux-Dudon et al., 2010) for LGM climate conditions of the order of three centuries and might need consideration in future gas chronologies.

Slow waves occurring during non-rapid eye movement sleep have been associated with neurobehavioural performance and memory. In addition, the duration of previous wakefulness and sleep impacts characteristics of these slow waves. However, molecular mechanisms regulating the dynamics of slow-wave characteristics remain poorly understood. The EphA4 receptor regulates glutamatergic transmission and synaptic plasticity, which have both been linked to sleep slow waves. To investigate if EphA4 regulates slow-wave characteristics during non-rapid eye movement sleep, we compared individual parameters of slow waves between EphA4 knockout mice and wild-type littermates under baseline conditions and after a 6-h sleep deprivation. We observed that, compared with wild-type mice, knockout mice display a shorter duration of positive and negative phases of slow waves under baseline conditions and after sleep deprivation. However, the mutation did not change slow-wave density, amplitude and slope, and did not affect the sleep deprivation-dependent changes in slow-wave characteristics, suggesting that EphA4 is not involved in the response to elevated sleep pressure. Our present findings suggest a role for EphA4 in shaping cortical oscillations during sleep that is independent from sleep need. © 2017 European Sleep Research Society.

The 39-year history of the Teratology Society is reviewed. An abbreviated history is outlined in table form, along with listings of the Warkany Lectures, the postgraduate courses, and officers of the Society. A year-by-year description of the events, including the scientific and social content of the annual meetings and changes in the business of the Society, is given, in many cases using comments from the past presidents. The valuable and unique diversity of the members is discussed and illustrated, presenting the disciplines and main research area of the presidents. The number of submitted abstracts and the various categories are tabulated, averaging the number and type over four periods. Within the past 10 years, a significant increase in the number of abstracts dealing with epidemiology and developmental biology is evident. The Society's development is compared with that of a human, and the question is asked: Have we reached the maturational stage of old age or senescence, or is the Society still maturing gracefully? This question needs further discussion by all the members. During the past 40 years, we have developed the scientific basis to prevent birth defects caused by rubella, alcoholism, and folate deficiency, as well as many other prenatal exposures. We must now engage in the political battles to obtain the resources needed to conduct further research and to implement the prevention programs, as well as to provide care and rehabilitation for persons with birth defects.

The aim of this study is to assess the changes in the causes of valvular heart disease between 2006 and 2011 in Korea. Data were collected from the Korean National Health Insurance Service from 2006 through 2011. These data consisted of primary diagnoses related to valvular heart disease regardless of other conditions. Valvular heart disease included non-rheumatic mitral valve disorders, non-rheumatic aortic valve disorders, rheumatic mitral valve disorders, and rheumatic aortic valve disorders. Overall, the age-standardized cumulative prevalence of non-rheumatic valvular heart disease was 70.6 per 100,000 persons in 2006 and 110.3 in 2011. This represented an increase from 42.2 to 65.2 in women and from 28.4 to 45.1 in men. In particular, there was a greater increase in prevalence in patients aged 65 years or older compared with groups aged 20-44 years or 45-64 years for both genders. The age-standardized cumulative prevalence of rheumatic valve disease did not change dramatically between 2006 and 2011. The overall age-standardized cumulative prevalence of non-rheumatic valvular heart diseases increased between 2006 and 2011, especially in individuals older than 65 years. These changes should be considered in future designs of cardiovascular healthcare services in countries with a rapidly aging population. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

AIM: To investigate the impact of MK-801 on gene expression patterns genome wide in rat brain regions. METHODS: Rats were treated with an intraperitoneal injection of MK-801 [0.08 (low-dose) and 0.16 (high-dose) mg/kg] or NaCl (vehicle control). In a first series of experiment, the frontoparietal electrocorticogram was recorded 15 min before and 60 min after injection. In a second series of experiments, the whole brain of each animal was rapidly removed at 40 min post-injection, and different regions were separated: amygdala, cerebral cortex, hippocampus, hypothalamus, midbrain and ventral striatum on ice followed by DNA microarray (4 × 44 K whole rat genome chip) analysis. RESULTS: Spectral analysis revealed that a single systemic injection of MK-801 significantly and selectively augmented the power of baseline gamma frequency (30-80 Hz) oscillations in the frontoparietal electroencephalogram. DNA microarray analysis showed the largest number (up- and down- regulations) of gene expressions in the cerebral cortex (378), midbrain (376), hippocampus (375), ventral striatum (353), amygdala (301), and hypothalamus (201) under low-dose (0.08 mg/kg) of MK-801. Under high-dose (0.16 mg/kg), ventral striatum (811) showed the largest number of gene expression changes. Gene expression changes were functionally categorized to reveal expression of genes and function varies with each brain region.

Purpose - In 2004, the American Association of Physicists in Medicine (AAPM) issued a report outlining recommended 125 I and 103 Pd datasets for consistency in calculating brachytherapy dose distributions. In 2005, to aid evaluating the clinical impact of implementing these datasets, the AAPM assessed the historical dependence of how prescribed doses differed from administered doses for 125 I and 103 Pd for permanent implantation of the prostate. Consequently, the American Brachytherapy Society (ABS) considered the nature of these changes towards issuing recommended dose prescriptions for 125 I and 103 Pd interstitial brachytherapy implants for mono-therapy and standard boosts. Methods and materials - An investigation was performed of the 2005 AAPM analysis to determine changes in administered dose while affixing prescribed dose using 2004 AAPM 125 I and 103 Pd brachytherapy dosimetry datasets for prostate implants. For 125 I and 103 Pd, administered dose would change by +1.4% and +4.2%, respectively. The biological and societal impact of changing prescribed dose was considered. Results - Based on the need for clinical constancy and in recognition of overall uncertainties, the ABS recommends immediate implementation of the 2004 AAPM consensus brachytherapy dosimetry datasets and no changes to 125 I and 103 Pd dose prescriptions at this time. Conclusions - Radiation oncologists should continue to prescribe mono-therapy doses of 145 Gy and 125 Gy for 125 I and 105 Pd, respectively, and standard boost doses of 100-110 Gy and 90-100 Gy for 125 I and 103 Pd, respectively.

2013-01-01

Full Text Available In a knowledge - based society, organizations undergo permanent changes and transformations, and the key factor of such changes is intellectual capital regarded as one of the most critical, yet most strategic values an organization might own. Analyzing intelectual capital and knowledge society over the last decades has primarily emerged in private companies, whereas at present there is an increasing concern in all the fields of activity. The goal of this paper is to emphasize the importance of intellectual capital as a source of innovation and novelty used to create competitive advantages for organizations in the era of knowledge where man must rely on intellect, intuition and creativity. The present paper is an exploratory endeavour based on the qualitative method as various information sources are resorted to in order to conceptualize the terms of intellectual capital and knowledge society: specialty literature, case studies, mass-media articles, reports of in-field organizations etc. Organizations should use all the tangible or non-tangible resources they have in order to secure their success and also to build a knowledge society which involves going a long way, based on an ample, complex process where innovation has a major role and a global nature.

Full Text Available The aim of this study was to assess changes in indirect markers of muscle damage and type I collagen degradation, as well as, patellar and Achilles tendon morphological differences during nine daily drop-jumps sessions with constant load alternated with rapid increases in load to test the hypothesis that frequent drop-jump training results in negative muscular and tendon adaptation. Young men (n = 9 performed daily drop jump workouts with progression every 3 days in terms of number of jumps, platform height and squat amplitude. Voluntary and electrically evoked knee extensor torque, muscle soreness, blood plasma creatine kinase (CK activity and carboxyterminal cross-linked telopeptide (ICTP, patellar and Achilles tendon thickness and cross-sectional area (CSA were assessed at different time points during the training period and again on days 1, 3, 10 and 17 after the training. The findings were as follows: (1 steady decline in maximal muscle strength with major recovery within 24 hours after the first six daily training sessions; (2 larger decline in electrically induced muscle torque and prolonged recovery during last three training sessions; (3 increase in patellar and Achilles tendons CSA without change in thickness towards the end of training period; (4 increase in jump height but not in muscle strength after whole training period. Our findings suggest that frequent drop-jump sessions with constant load alternated with rapid increases in load do not induce severe muscle damage or major changes in tendons, nonetheless, this type of loading is not advisable for muscle strength improvement.

A history of the American Society for Clinical Investigation

Howell, Joel D.

2009-01-01

One hundred years ago, in 1909, the American Society for Clinical Investigation (ASCI) held its first annual meeting. The founding members based this new society on a revolutionary approach to research that emphasized newer physiological methods. In 1924 the ASCI started a new journal, the Journal of Clinical Investigation. The ASCI has also held an annual meeting almost every year. The society has long debated who could be a member, with discussions about whether members must be physicians, what sorts of research they could do, and the role of women within the society. The ASCI has also grappled with what else the society should do, especially whether it ought to take a stand on policy issues. ASCI history has reflected changing social, political, and economic contexts, including several wars, concerns about the ethics of biomedical research, massive increases in federal research funding, and an increasingly large and specialized medical environment.

It is now widely recognized that the complexity of climate change issues translates itself into a need for interdisciplinary approaches to science. This allows to first achieve a more comprehensive vision of climate change and, second, to better inform the decision-making processes. However, it seems that willingness alone is rarely enough to implement interdisciplinarity. The purpose of this presentation is to mobilize reflexivity to revisit and analyze the experience of the Paris Consortium for Climate-Environment-Society. The French Consortium Climate-Environment-Society aims to develop, fund and coordinate interdisciplinary research into climate change and its impacts on society and environment. Launched in 2007, the consortium relies on the research expertise of 17 laboratories and federation in the Paris area working mainly in the fields of climatology, hydrology, ecology, health sciences, and the humanities and social sciences. As examples, economists and climatologists have studied greenhouse gas emission scenarios compatible with climate stabilization goals. Historical records have provided both knowledge about past climate change and vulnerability of societies. Some regions, as the Mediterranean and the Sahel, are particularly vulnerable and already have to cope with water availability, agricultural production and even health issues. A project showed that millet production in West Africa is expected to decline due to warming in a higher proportion than observed in recent decades. Climate change also raises many questions concerning health: combined effects of warming and air quality, impacts on the production of pollens and allergies, impacts on infectious diseases. All these issues lead to a need for approaches integrating different disciplines. Furthermore, climate change impacts many ecosystems which, in turn, affect its evolution. Our experience shows that interdisciplinarity supposes, in order to take shape, the conjunction between programming

Lykken, Sara

2013-01-01

The rapidly evolving realm of modern commerce strains traditional regulatory paradigms. This paper traces the historical evolution of FDA crisis-response regulation and provides examples of ways in which the definitions and procedures resulting from that past continue to be challenged by new products as market entrants, some in good faith and others not, take actions that create disconnects between actual product and marketing controls and those that consumers might expect. The paper then explores some of the techniques used by other federal agencies that have faced similar challenges in environments characterized by rapid innovation, and draws from this analysis suggestions for improvement of the FDA's warning letter system.

Chlamydia trachomatis infections present a major heath burden worldwide. The conventional method used to detect C. trachomatis is laborious. In the present study, a novel strategy was utilized to evaluate the impact of antimicrobial agents on the growth of C. trachomatis and its expression of ompA promoter-driven green fluorescence protein (GFP). We demonstrate that this GFP reporter system gives a robust fluorescent display of C. trachomatis growth in human cervical epithelial cells and, further, that GFP production directly correlates to changes in ompA expression following sufficient exposure to antimicrobials. Validation with azithromycin, the first-line macrolide drug used for the treatment of C. trachomatis infection, highlights the advantages of this method over the traditional method because of its simplicity and versatility. The results indicate both that ompA is highly responsive to antimicrobials targeting the transcription and translation of C. trachomatis and that there is a correlation between changing GFP levels and C. trachomatis growth. This proof-of-concept study also reveals that the ompA-GFP system can be easily adapted to rapidly assess antimicrobial effectiveness in a high-throughput format.

By 1965, the policies and programs of Lyndon B. Johnson's Great Society brought optimism to black physicians and a new wave of resistance against black civil rights advocates in the American South. The largest of the first Head Start programs, Child Development Group of Mississippi (CDGM), had its roots in Freedom Summer 1964 and the Medical Committee for Human Rights. Like other proposed programs with strong medical components, CDGM was caught in a legislative Bermuda triangle created by the powerful Mississippi congressional delegation to maintain white supremacy and plantation economics. Physician-led investigations exposed the extraordinary level of poor health among Mississippi's black children, supported Head Start as a remedy, and awakened the white medical establishment to health disparities of the Jim Crow period. It was also the beginning of positive change in the previously silent white medical community in the South and their support of civil justice in health.

In the century our earth experienced a rapid environment changes due to strong human activities, which impactedthe earth'shydrology and water resources systems negatively, and causedsevere problems to the society, such as increased flood and drought risk, water pollution and ecosystem degradation. Understanding the variations of hydrological characteristics has important meaning to solve the problem of hydrology and water resources and maintain sustainable development of river basin water resources.This paper takesWujiangriveras an example,which is a typical medium watershedaffected by human activities seriously in southern China.Using the methods of Mann-Kendall test and serial cluster analysis, this paper studies the characteristics and laws of historical hydrological process inWujiang river, detectsthe impact of changing environment to watershed hydrological processes, based on the observed hydrological data of 36 years from 1980 to 2015 in three representative hydrological stationsnamedFenshi,Chixi and Pingshi. The results show that the annual runoffandannual precipitation has some kind of changes.

Space Weather, Environment and Societies

2006-01-01

Our planet exists within a space environment affected by constantly changing solar atmosphere producing cosmic particles and electromagnetic waves. This "space weather" profoundly influences the performance of our technology because we primarily use two means for transmitting information and energy; namely, electromagnetic waves and electricity. On an everyday basis, we have developed methods to cope with the normal conditions. However, the sun remains a fiery star whose 'angry' outbursts can potentially destroy spacecrafts, kill astronauts, melt electricity transformers, stop trains, and generally wreak havoc with human activities. Space Weather is the developing field within astronomy that aims at predicting the sun’s violent activity and minimizing the impacts on our daily lives. Space Weather, Environment, and Societies explains why our technological societies are so dependent on solar activity and how the Sun disturbs the transmission of information and energy.

"The Human Condition" as social ontology: Hannah Arendt on society, action and knowledge.

Science.gov (United States)

Walsh, Philip

2011-01-01

Hannah Arendt is widely regarded as a political theorist who sought to rescue politics from "society," and political theory from the social sciences. This conventional view has had the effect of distracting attention from many of Arendt's most important insights concerning the constitution of "society" and the significance of the social sciences. In this article, I argue that Hannah Arendt's distinctions between labor, work, and action, as these are discussed in "The Human Condition" and elsewhere, are best understood as a set of claims about the fundamental structures of human societies. Understanding Arendt in this way introduces interesting parallels between Arendt's work and both classical and contemporary sociology. From this I draw a number of conclusions concerning Arendt's conception of "society," and extend these insights into two contemporary debates within contemporary theoretical sociology: the need for a differentiated ontology of the social world, and the changing role that novel forms of knowledge play in contemporary society as major sources of social change and order.

High-resolution temperature records spanning the last deglaciation from low latitudes are scarce; however, they are important for understanding the rapid propagation of abrupt climate events throughout the Northern Hemisphere and the tropics. Here, we present a branched GDGTs-based temperature reconstruction from the sediments of Maar Lake Huguangyan in tropical China. The record reveals that the mean temperature during the Oldest Dryas was 17.8 °C, which was followed by a two-step increase of 2-3 °C to the Bølling-Allerød, a decrease to 19.8 °C during the Younger Dryas, and a rapid warming at the onset of the Holocene. The Oldest Dryas was about 2 °C warmer than the Younger Dryas. The reconstructed temperature was weighted towards the wintertime since the lake is monomictic and the mixing process in winter supplies nutrients from the lake bottom to the entire water column, greatly promoting biological productivity. In addition, the winter-biased temperature changes observed in the study are more distinctive than the summer-biased temperature records from extra-tropical regions of East Asia. This implies that the temperature decreases during abrupt climatic events were mainly a winter phenomenon. Within the limits of the dating uncertainties, the broadly similar pattern of winter-weighted temperature change observed in both tropical Lake Huguangyan and in Greenland ice cores indicates the occurrence of tightly-coupled interactions between high latitude ice sheets and land areas in the tropics. We suggest that the winter monsoon (especially cold surges) could play an important role in the rapid transmission of the temperature signal from the Arctic to the tropics.

Economic analyses of rapid population growth.

Birdsall, N

1989-01-01

"Discussion of the macroeconomic consequences of rapid population growth is organized into three schools: pessimists, optimists, and the recent revisionists. For the revisionists, differing views are presented about the pervasiveness and relevance of market failures, such as the negative externalities of childbearing, and about the ability of families and institutions to adjust rapidly to changes brought on by rapid population growth. A welfare economics approach is used to review the merits of various public policies to reduce fertility, including public financing of family planning services and taxes and incentives associated with childbearing." The focus is on developing countries. excerpt

Key features for more successful place-based sustainability research on social-ecological systems: a Programme on Ecosystem Change and Society (PECS perspective

2017-03-01

Full Text Available The emerging discipline of sustainability science is focused explicitly on the dynamic interactions between nature and society and is committed to research that spans multiple scales and can support transitions toward greater sustainability. Because a growing body of place-based social-ecological sustainability research (PBSESR has emerged in recent decades, there is a growing need to understand better how to maximize the effectiveness of this work. The Programme on Ecosystem Change and Society (PECS provides a unique opportunity for synthesizing insights gained from this research community on key features that may contribute to the relative success of PBSESR. We surveyed the leaders of PECS-affiliated projects using a combination of open, closed, and semistructured questions to identify which features of a research project are perceived to contribute to successful research design and implementation. We assessed six types of research features: problem orientation, research team, and contextual, conceptual, methodological, and evaluative features. We examined the desirable and undesirable aspects of each feature, the enabling factors and obstacles associated with project implementation, and asked respondents to assess the performance of their own projects in relation to these features. Responses were obtained from 25 projects working in 42 social-ecological study cases within 25 countries. Factors that contribute to the overall success of PBSESR included: explicitly addressing integrated social-ecological systems; a focus on solution- and transformation-oriented research; adaptation of studies to their local context; trusted, long-term, and frequent engagement with stakeholders and partners; and an early definition of the purpose and scope of research. Factors that hindered the success of PBSESR included: the complexities inherent to social-ecological systems, the imposition of particular epistemologies and methods on the wider research group

Efficiency of the building societies in the Czech Republic

Full Text Available This paper is the first attempt to analyze efficiency of building societies in the Czech Republic. We apply non-parametric method Data Envelopment Analysis on data from all building societies in the sector over the period 2002–2008. Having deposits received and administrative expenses as inputs and volume of loans disbursed as output we estimate efficiency scores of all individual building societies as well as calculate the average efficiency in the industry. For this purpose we use two alternative models that allows for constant and variable returns of scale respectively. The results suggest that there is no significant improvement in efficiency of building societies during the estimation period. Furthermore, most of the building societies have not been operating at appropriate size. We also found that Českomoravská stavební spořitelna, a. s. was the most efficient building society in the Czech Republic according to the both models applied. In order to increase efficiency, we suggest reduction in the number of external employees and agents or increase of their productivity, more sophisticated products that can outperform the standard services and effective response to changes in the legislature.

Radiation Protection in Slovenia Over the Past Fifty Years (1963-2013) and the Slovenian Society of Radiation Protection

Omahen, G.; Krizman, M.J.

2013-01-01

The use of the ionizing radiation sources in Slovenia started as early as 1900 when X-ray device was put in operation; the first radioactive source was used two years later. Artificial radioactive sources were introduced from 1954 onwards. The use of radioactive sources in industry started in the middle of the 1950's when industrial radiography was introduced due to strong metal industry in Slovenia. Four nuclear facilities were built in Slovenia: the research reactor TRIGA (1966), the Krško nuclear power plant (1983), the mining and milling uranium complex at Žirovski Vrh (1984) and the low and intermediate level radioactive waste storage (1986). The infrastructure of radiation protection (RP) in the former Yugoslavia was established as late as the first Law on RP was adopted in 1959, the competent authorities were defined and technical support organisations for RP were designated. But the whole infrastructure could not follow the rapid development of nuclear industry and the extent uses of sources. After joining EU, the changes in legislation made a significant shift ahead in radiation protection, as regards the quality of the implementation of radiation protection measures as the intensity of administrative and inspection controls. Slovenian Radiation Protection Society was established in 1981 during the 11th symposium of the Yugoslav Radiation Protection Society. The role of the Slovenian Society for Radiation Protection has never been significant, mostly due to a small critical mass of membership. This is sometimes advantageous since everyone knows each other and can easily come with the problem to be solved. This feature reduces the need for the Society to be active as a formal association. The main role of the Society is the distribution of actual information on RP and related important events.(author)

Risk and society: The interaction of science, technology and public policy

International Nuclear Information System (INIS)

Waterstone, M.

1992-01-01

Risk and Society is the sixth volume in Kluwer's Technology, Risk, and Society series, and like the previous volumes in this series, it is made up of papers presented at a symposium convened in 1989 to discuss the changing interactions of technology and society and definitions of risk. The papers presented all center around risk as a constructed phenomenon. The first paper is a general overview of concepts of risk in society and the changing emphasis on risk in the last two decades. The papers represent four main topic areas: Risk, science and public policy; Allocating scarce medical resources; Nuclear power and nuclear waste disposal; and Setting standards for air quality. Three papers, representing three different points of view, are presented in each topic area. The contributors cover a range of issues in this format, and the combined effect is a good overview of the issues with which risk assessors, risk managers, and public policymakers must grapple if constructive use is to be made of risk in public decision-making

Shifts in frog size and phenology: Testing predictions of climate change on a widespread anuran using data from prior to rapid climate warming.

Changes in body size and breeding phenology have been identified as two major ecological consequences of climate change, yet it remains unclear whether climate acts directly or indirectly on these variables. To better understand the relationship between climate and ecological changes, it is necessary to determine environmental predictors of both size and phenology using data from prior to the onset of rapid climate warming, and then to examine spatially explicit changes in climate, size, and phenology, not just general spatial and temporal trends. We used 100 years of natural history collection data for the wood frog, Lithobates sylvaticus with a range >9 million km 2 , and spatially explicit environmental data to determine the best predictors of size and phenology prior to rapid climate warming (1901-1960). We then tested how closely size and phenology changes predicted by those environmental variables reflected actual changes from 1961 to 2000. Size, phenology, and climate all changed as expected (smaller, earlier, and warmer, respectively) at broad spatial scales across the entire study range. However, while spatially explicit changes in climate variables accurately predicted changes in phenology, they did not accurately predict size changes during recent climate change (1961-2000), contrary to expectations from numerous recent studies. Our results suggest that changes in climate are directly linked to observed phenological shifts. However, the mechanisms driving observed body size changes are yet to be determined, given the less straightforward relationship between size and climate factors examined in this study. We recommend that caution be used in "space-for-time" studies where measures of a species' traits at lower latitudes or elevations are considered representative of those under future projected climate conditions. Future studies should aim to determine mechanisms driving trends in phenology and body size, as well as the impact of climate on population

FROM GLOBALIZATION TO GLOBALITY- MERGING NON- WESTERN (POST COLONIAL AND WESTERN SOCIETIES INTO A GLOBAL MODERNITY

Directory of Open Access Journals (Sweden)

2014-12-01

Full Text Available Modernity stands as a widely used term for social change as it involves modification in many forms in the society and the way people develop with different ideologies and movements. Standing on the other side of the traditional and historical, modernity brings new forms of development, communication and connectedness. In this paper it would be discussed whether the globalization processes are leading to merging of the societies and raising a global modernity, hence the influence of the West and the pilgrimages drawn on the other societies would be examined. Change is an unavoidable part of the society seen as a reform, reaction or revolution. However, the historical processes of integration, innovation and development bring different questions and theories. In this paper it would be referred on the integrative inclinations for merging societies, the understanding of modernity and globalization processes that emerge from the historical development and social change.

1999-01-01

This book brings together the communications presented at the colloquium 'risk and society' held in Paris (France) on November 1998. During this colloquium, the various aspects of risk and of its management were discussed by medical specialists, historians, industrialists, engineers, philosophers, lawyers, politicians and administration representatives. The first theme concerns the controversies generated by the development of some activities (genetics, bio-technologies, nuclear and radiations use). The second theme concerns the management of risks and the way to conciliate the point of view of authorities and citizens (confidence of the public with respect to experts, scientists, industrialists, government and administrative representatives, role played by the media). The debates that took place during the colloquium have shown that the public opinion concerning the nuclear activities or the new technologies greatly depends on the ideological attitudes and on the public's likes and dislikes with respect to some categories of actors (distrust with respect to public decisions, fears with respect to changes and future, nostalgia of the past). The following aspects are reviewed: Notions of risk and hazard (risk and health, risk in today's society, medicine and society, the point of view of the industrialists and of the scientific and technical specialists); from the psychological aspects of the risk to its social aspects (survey of the risk assessment battlefield, social attenuation and amplification of risk, the feeling of risks in Europe, insecurity and delinquency, controversies around radioactivity and health); the negotiation and communication about risks (risk and public health, negotiation around risks, risks and information dissemination about the public debate, communication and crisis, evolution of risk communication, comparison between American and European approaches, the Seveso directive); the public debate and the evolution of risks management (the

The technologies prefixed with 'super' have offered the conveniences in the various aspects of the society including the industrial field up to present. Firstly a conception 'super high speed transportation system' has realized the 'supersonic aircraft' and 'ultra super express train', etc. such as a linear motor car, and moreover is developing the 'superconducting propulsive ship' and so forth. In the information oriented society, the information processing speed of computer has made a rapid progress by the development of very high speed large scale integrated circuit etc. In the field of manufacture, there are the magnetic head of video tape recorder and the lens of camera as products close to us manufactured by the 'super precision working.' As for the products adhered closely to ous lives, there are medical equipments, wedling machine, fish detector, etc. utilizing the 'ultrasonic wave', as well as 'supermultistoried building,' etc. Furthermore, turning a loon on the world of culture and art, the activities of the 'surrealism' are giving a substantial effect. It is important that the technology prefixed with 'super' will be let developed, and not only the conveniences, but also the harmony between the human being and nature will be realized in a better form in the future as well.

2002-01-01

The Dutch Electricity Technology Roadmap Initiative is being developed by KEMA as a joint effort of Dutch and European experts of universities, industry and (non)governmental organisations. It aims to assess how to structure the ongoing collaborative research and technological advancement, the exploration of the opportunities and the threats for the electricity-based innovations over the next twenty-five years. In addition it analyses how to manage the transition towards a knowledge based economy and a more sustainable society. To date, about 100 organisations have participated with KEMA and its sponsors in shaping a comprehensive vision of the opportunities to structure the knowledge based economy in the Digital Society with as basis the increase of electricity's value to society. This vision is being translated into a set of technology development destinations and a total of six distinct initiatives for targeted projects. KEMA is leading this ongoing road-mapping effort, with the support of TENNET and EPRI (USA). The Dutch power generation utilities and the Ministry of Economics (EZ) financially support the work. It is an investment in the future of the Dutch knowledge based economy and a guidance to structure and strengthen the value of public and private RandD investments. The Electricity Technology Roadmap Initiative explores a period of fast regulatory, political, technological and institutional change in the electricity enterprise and in the society. The strategic choices made in this period of change can have profound consequences on whether future opportunities are opened or closed, and whether threats increase or are eliminated The reluctance to proceed with important changes is understandable, given the extreme uncertainty under which decisions must be made. No regrets solutions may be appropriate in some circumstances. These situations highlight the need for foresight and the importance of strategic roadmapping. The first year of the Roadmap

Nicholson Medal Lecture: Scientists and Totalitarian Societies

In order to call for support for his policy in China from the scientific community outside of China, Li Peng, China's premier today and at the time of Tiananmen massacre in 1989, published an editorial of ``Science" magazine (July 5, 1996) titled ``Why China needs science ... and partners." This editorial brought a serious problem, which is originally faced by scientists in a totalitarian society, upon the scientific community in free societies outside. It is well known that the current attitude of the Chinese government toward science is what it was during the years of Mao and the Soviet Union: science is limited to provide instruments useful to the rulers, but any degree of freedom, such as to challenge ideas, required by science to change the totalitarian regime itself, is suppressed. Thus, the problem facing us is: how to help your colleagues and promote science in a totalitarian society, without becoming a partner of the injustices of that regime.

Evidence relating the rate of change in renal function, measured as eGFR, after antihypertensive treatment in elderly patients to clinical outcome is sparse. This study characterized the rate of change in eGFR after commencement of antihypertensive treatment in an elderly population, the factors associated with eGFR rate change, and the rate's association with all-cause and cardiovascular mortality. Data from the Second Australian National Blood Pressure study were used, where 6083 hypertensive participants aged ≥65 years were enrolled during 1995-1997 and followed for a median of 4.1 years (in-trial). Following the Second Australian National Blood Pressure study, participants were followed-up for a further median 6.9 years (post-trial). The annual rate of change in the eGFR was calculated in 4940 participants using creatinine measurements during the in-trial period and classified into quintiles (Q) on the basis of the following eGFR changes: rapid decline (Q1), decline (Q2), stable (Q3), increase (Q4), and rapid increase (Q5). A rapid decline in eGFR in comparison with those with stable eGFRs during the in-trial period was associated with older age, living in a rural area, wider pulse pressure at baseline, receiving diuretic-based therapy, taking multiple antihypertensive drugs, and having blood pressure <140/90 mmHg during the study. However, a rapid increase in eGFR was observed in younger women and those with a higher cholesterol level. After adjustment for baseline and in-trial covariates, Cox-proportional hazard models showed a significantly greater risk for both all-cause (hazard ratio, 1.28; 95% confidence interval, 1.09 to 1.52; P=0.003) and cardiovascular (hazard ratio, 1.40; 95% confidence interval, 1.11 to 1.76; P=0.004) mortality in the rapid decline group compared with the stable group over a median of 7.2 years after the last eGFR measure. No significant association with mortality was observed for a rapid increase in eGFR. In elderly persons with

Future success in microelectronics will demand rapid innovation, rapid product introduction and ability to react to a change in technological and business climate quickly. These technological advances in integrated electronics will require development of flexible manufacturing technology for VLSI systems. However, the current approach of establishing factories for mass manufacturing of chips at a cost of more than 200 million dollars is detrimental to flexible manufacturing. The authors propose concepts of a micro factory which may be characterized by more economical small scale production, higher flexibility to accommodate many products on several processes, and faster turnaround and learning. In-situ multiprocessing equipment where several process steps can be done in sequence may be a key ingredient in this approach. For this environment to be flexible, the equipment must have ability to change processing environment, requiring extensive in-situ measurements and real time control. This paper describes the development of a novel single wafer rapid thermal multiprocessing (RTM) reactor for next generation flexible VLSI manufacturing. This reactor will combine lamp heating, remote microwave plasma and photo processing in a single cold-wall chamber, with applications for multilayer in-situ growth and deposition of dielectrics, semiconductors and metals

Social Change and its Potential Impacts on Chinese Population Health

Wang, Hong

2004-12-01

Full Text Available Within the past 25 years, China has experienced transformation of its economic system from a highly centralized planned economy toward a market oriented economic system. This process has led to massive and rapid changes in all aspects of society with profound effects on the population’s health in the large parts of the country. Along with the material prosperity, the living conditions of Chinese people, such as food, shelter, and sanitation status, have been improving steadily. People have more capability to purchase health related merchandise as well as health services. Overall the health status of most Chinese has improved but there are significant exceptions to this overall conclusion. These exceptions arise from increasing inequity of income, increases in unemployment rates, the decline of health insurance coverage, changes in demography, changes in social value, culture, health related behaviors, and the changes of health care systems.

Full Text Available Learned societies have become aligned with commercial publishers, who have increasingly taken over the latter’s function as independent providers of scholarly information. Using the example of geographical societies, the advantages and disadvantages of this trend are examined. It is argued that in an era of digital publication, learned societies can offer leadership with a new model of open access that can guarantee high quality scholarly material whose publication costs are supported by society membership dues.

Risk perceptions and public debates on climate change: a conceptualisation based on the theory of a functionally-differentiated society

Markus Rhomberg

2010-11-01

Full Text Available Mass media and its mechanisms of production and selection play a crucial role in the definition of climate change risks. Different form of logic in the political, scientific and media systems are vital aspects in the public debate on this issue. A theoretical analysis of these aspects needs a framework in terms of social theory: Luhmann’s concept of a functionally-differentiated society and the mechanisms of structural couplings could help to understand the relations and interplay of these systems in the climate-debate. Based on this framework and various empirical studies, this paper suggests: different logics lead to different climate-definitions in science, politics and mass media. Climate change became interesting, but not until it was located in the political decision-making process. Climate issues become publicly interesting, when they are clear, contentious and can be linked to Elite-Persons. In contrast to scientific communication, news media make great efforts to be clear and definite in their communications.

Indian Vacuum Society: The Indian Vacuum Society

The Indian Vacuum Society (IVS) was established in 1970. It has over 800 members including many from Industry and R & D Institutions spread throughout India. The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

Technology and society - conflict or symbiosis?

Laermann, K.H.

1996-01-01

The conclusion drawn in this paper on the conflict between technology and society is: 1. One must not assess science and technology solely from the angle of economic and social aspects with regard to necessity or effects. They have to be seen under a new paradigma devoted to mankind and humanity and within the framework of a future-oriented concept, fitting into an overall picture of life and nature on earth. 2. Science and technology have a decisive impact on cultural and social developments across the world, and not only in our society, contributing to a change in feeling and thinking, modifying ethical and cultural concepts. 3. Science and technology offer a chance to cope with essential challenges to life in the present and in the future. (orig./DG) [de

Are rapid changes in brain elasticity possible?

Science.gov (United States)

Parker, K. J.

2017-09-01

Elastography of the brain is a topic of clinical and preclinical research, motivated by the potential for viscoelastic measures of the brain to provide sensitive indicators of pathological processes, and to assist in early diagnosis. To date, studies of the normal brain and of those with confirmed neurological disorders have reported a wide range of shear stiffness and shear wave speeds, even within similar categories. A range of factors including the shear wave frequency, and the age of the individual are thought to have a possible influence. However, it may be that short term dynamics within the brain may have an influence on the measured stiffness. This hypothesis is addressed quantitatively using the framework of the microchannel flow model, which derives the tissue stiffness, complex modulus, and shear wave speed as a function of the vascular and fluid network in combination with the elastic matrix that comprise the brain. Transformation rules are applied so that any changes in the fluid channels or the elastic matrix can be mapped to changes in observed elastic properties on a macroscopic scale. The results are preliminary but demonstrate that measureable, time varying changes in brain stiffness are possible simply by accounting for vasodynamic or electrochemical changes in the state of any region of the brain. The value of this preliminary exploration is to identify possible mechanisms and order-of-magnitude changes that may be testable in vivo by specialized protocols.

The author presents a summarizing view of the things we are letting ourselves in for on our way from the postindustrial to the postinformative and finally the postmaterial society: - Internationalization, 'stronger decentralization' and a 'multi-optional society' e.g. (pseudo)-individual wishes will be considered even more - awareness of the interlinkages in the world and the fact that all things are interdependent will grow - working life will be a combination of performance and pleasure - globally speaking it is much harder to prognosticate the economic development than the social one because it is not unreasonable to expect a severe crash of the world economy in the not too distant future. We all live in times which are a-changing. Let us be confident that these changes will bring about a better world - even through we see problems and imperfections whenever we take a closer look at things. (orig./HSCH) [de

About 6.3% ASHAs were not fulfilling the educational criteria of selection (education upto 8th class. Study reported that majority of ASHA consider care of pregnant women, vaccination and family planning as their prime services. 42% ASHA reported that they think this work can pave their ways for future employment. Conclusion: Supervisory body should see that selection of ASHA should be as per stipulated criteria and they should be sensitized about their major role of motivator & activist, for creating awareness and demand generation in the society.

Mechanisms of Social Consolidation in the Network Society

Directory of Open Access Journals (Sweden)

Lidia A. Bobova

2014-01-01

Full Text Available During the last five years the world has seen the emergence of mass global and regional social movements outside of institutional structures representing open systems with a spontaneous nature. These social movements do not have any tangible hierarchy and leaders; information within the movement activity is spread virally and mainly using new electronic communication tools - namely, mass self-communication constituting spaces of communication autonomy beyond the control of governments. A feature of the new type of social movements is their emergence in virtual space. Such mass movements manifest intensified consolidation processes in the modern society - due to fundamentally new factors. New practical mechanisms of consolidation amid an increase in the proportion of young people in countries are directly linked with technological developments that influenced in essence communication and changes in the established modern informational society. Virtual mass self-communication becomes the main practical mechanism for social consolidation in the modern informational society. The consolidation process intensifies due to government legitimacy crisis and loss of public trust in government and indicates an emergence of a new form of a civil society.

Rapid environmental change over the past decade revealed by isotopic analysis of the California mussel in the northeast Pacific.

Directory of Open Access Journals (Sweden)

Catherine A Pfister

Full Text Available The anthropogenic input of fossil fuel carbon into the atmosphere results in increased carbon dioxide (CO(2 into the oceans, a process that lowers seawater pH, decreases alkalinity and can inhibit the production of shell material. Corrosive water has recently been documented in the northeast Pacific, along with a rapid decline in seawater pH over the past decade. A lack of instrumentation prior to the 1990s means that we have no indication whether these carbon cycle changes have precedence or are a response to recent anthropogenic CO(2 inputs. We analyzed stable carbon and oxygen isotopes (δ(13C, δ(18O of decade-old California mussel shells (Mytilus californianus in the context of an instrumental seawater record of the same length. We further compared modern shells to shells from 1000 to 1340 years BP and from the 1960s to the present and show declines in the δ(13C of modern shells that have no historical precedent. Our finding of decline in another shelled mollusk (limpet and our extensive environmental data show that these δ(13C declines are unexplained by changes to the coastal food web, upwelling regime, or local circulation. Our observed decline in shell δ(13C parallels other signs of rapid changes to the nearshore carbon cycle in the Pacific, including a decline in pH that is an order of magnitude greater than predicted by an equilibrium response to rising atmospheric CO(2, the presence of low pH water throughout the region, and a record of a similarly steep decline in δ(13C in algae in the Gulf of Alaska. These unprecedented changes and the lack of a clear causal variable underscores the need for better quantifying carbon dynamics in nearshore environments.

Mandibular dental arch short and long-term spontaneous dentoalveolar changes after slow or rapid maxillary expansion: a systematic review

Directory of Open Access Journals (Sweden)

Arthur César de Medeiros Alves

Full Text Available ABSTRACT Objective: The aim of this systematic review was to analyze the short and long-term spontaneous dentoalveolar changes of the mandibular dental arch after slow (SME or rapid (RME maxillary expansion in the mixed and early permanent dentitions. Methods: An electronic search was performed in the following databases: PubMed/Medline, Cochrane Library, Scopus, Embase and Web of Science. Eligibility criteria for article selection included randomized controlled trials and prospective studies written in English, with no restriction of year of publication, involving patients who underwent SME or RME during the mixed or early permanent dentitions. A double-blind search of articles was performed by two reviewers. Initially, the title and the abstract of the studies were read, and their references were also hand-searched for possible missing studies. A methodological quality scoring scale was used to analyze the selected articles. Results: The search retrieved 373 articles, but only 6 were selected for review after application of the eligibility and exclusion criteria. Non-clinically significant spontaneous dentoalveolar changes of approximately 1mm were found in the mandibular dental arch in the short and long-term, after slow or rapid maxillary expansions. Furthermore, no significant differences were found between treated and control groups. Conclusions: There is enough evidence to conclude that negligible short and long-term spontaneous dentoalveolar changes tend to occur in the mandibular dental arch after SME or RME in the mixed and early permanent dentitions. More randomized studies with appropriate control group are required to better evaluate this issue.

2013-10-01

China, the most populous country on Earth, has experienced rapid urbanization which is one of the main causes of many environmental and ecological problems. Therefore, the monitoring of rapid urbanization regions and the environment is of critical importance for their sustainable development. In this study, the object-based classification is employed to detect the change of land cover in Shenzhen, which is located in South China and has been urbanized rapidly in recent three decades. First, four Landsat TM images, which were acquired on 1990, 2000 and 2010, respectively, are selected from the image database. Atmospheric corrections are conducted on these images with improved dark-object subtraction technique and surface meteorological observations. Geometric correction is processed with ground control points derived from topographic maps. Second, a region growing multi-resolution segmentation and a soft nearest neighbour classifier are used to finish object-based classification. After analyzing the fraction of difference classes over time series, we conclude that the comparison of derived land cover classes with socio-economic statistics demonstrates the strong positive correlation between built-up classes and urban population as well as gross GDP and GDPs in second and tertiary industries. Two different mechanisms of urbanization, namely new land development and redevelopment, are revealed. Consequently, we found that, the districts of Shenzhen were urbanized through different mechanisms.

Full Text Available Emmanuel N Kontomanolis, Spyridon Michalopoulos, Grigorios Gkasdaris, Zacharias Fasoulakis Department of Obstetrics and Gynecology, Democritus University of Thrace, Alexandroupolis, Greece Abstract: AIDS is a devastating and deadly disease that affects people worldwide and, like all infections, it comes without warning. Specifically, childbearing women with AIDS face constant psychological difficulties during their gestation period, even though the pregnancy itself may be normal and healthy. These women have to deal with the uncertainties and the stress that usually accompany a pregnancy, and they have to live with the reality of having a life-threatening disease; in addition to that, they also have to deal with discriminating and stigmatizing behaviors from their environment. It is well known that a balanced mental state is a major determining factor to having a normal pregnancy and constitutes the starting point for having a good quality of life. Even though the progress in both technology and medicine is rapid, infected pregnant women seem to be missing this basic requirement. Communities seem unprepared and uneducated to smoothly integrate these people in their societies, letting the ignorance marginalize and isolate these patients. For all the aforementioned reasons, it is imperative that society and medical professionals respond and provide all the necessary support and advice to HIV-positive child bearers, in an attempt to allay their fears and relieve their distress. The purpose of this paper is to summarize the difficulties patients with HIV infection have to deal with, in order to survive and merge into society, identify the main reasons for the low public awareness, discuss the current situation, and provide potential solutions to reducing the stigma among HIV patients.

Apart from the journals they produce, scientific societies play an important role in communicating scientific findings and norms to the broader society. The American Association for the Advancement of Science (AAAS) includes among its goals to promote and defend the integrity of science and its use; provide a voice for science on societal issues; promote the responsible use of science in public policy; and increase public engagement with science and technology. AAAS websites and programs, including Communicating Science (www.aaas.org/communicatingscience), Working with Congress (http://www.aaas.org/spp/cstc/wwc/book.htm) and ScienceCareers.org (http://sciencecareers.sciencemag.org), provide tools for scientists to become more directly engaged in effectively communicating their findings and involved in the policy process. Education programs work to build the next generation of scientists and a science-literate public. To bridge the current communication gap between scientists, the public and policymakers, AAAS, like other scientific societies, maintains policy and outreach programs with limited budgets and staff. AAAS works to engage policymakers and provide scientific underpinning to key issues through congressional briefings, meetings, policy briefs, and media outreach. AAAS responds to challenges to accepted scientific findings and processes through op-eds, letters to government officials, resolutions, and Board statements. Some of these initiatives occur on a local level in partnership with local civic leaders, whose endorsement makes them more powerful. On a national scale, they assure that the voice of science is included in the debate. The changing media landscape presents opportunities and challenges for future AAAS endeavors.

We report a palaeomagnetic investigation of the last full geomagnetic field reversal, the Matuyama-Brunhes (M-B) transition, as preserved in a continuous sequence of exposed lacustrine sediments in the Apennines of Central Italy. The palaeomagnetic record provides the most direct evidence for the tempo of transitional field behaviour yet obtained for the M-B transition. 40Ar/39Ar dating of tephra layers bracketing the M-B transition provides high-accuracy age constraints and indicates a mean sediment accumulation rate of about 0.2 mm yr-1 during the transition. Two relative palaeointensity (RPI) minima are present in the M-B transition. During the terminus of the upper RPI minimum, a directional change of about 180 ° occurred at an extremely fast rate, estimated to be less than 2 ° per year, with no intermediate virtual geomagnetic poles (VGPs) documented during the transit from the southern to northern hemisphere. Thus, the entry into the Brunhes Normal Chron as represented by the palaeomagnetic directions and VGPs developed in a time interval comparable to the duration of an average human life, which is an order of magnitude more rapid than suggested by current models. The reported investigation therefore provides high-resolution integrated palaeomagnetic and radioisotopic data that document the fine details of the anatomy and tempo of the M-B transition in Central Italy that in turn are crucial for a better understanding of Earth's magnetic field, and for the development of more sophisticated models that are able to describe its global structure and behaviour.

Indian family systems, collectivistic society and psychotherapy.

Indian society is collectivistic and promotes social cohesion and interdependence. The traditional Indian joint family, which follows the same principles of collectivism, has proved itself to be an excellent resource for the care of the mentally ill. However, the society is changing with one of the most significant alterations being the disintegration of the joint family and the rise of nuclear and extended family system. Although even in today's changed scenario, the family forms a resource for mental health that the country cannot neglect, yet utilization of family in management of mental disorders is minimal. Family focused psychotherapeutic interventions might be the right tool for greater involvement of families in management of their mentally ill and it may pave the path for a deeper community focused treatment in mental disorders. This paper elaborates the features of Indian family systems in the light of the Asian collectivistic culture that are pertinent in psychotherapy. Authors evaluate the scope and effectiveness of family focused psychotherapy for mental disorders in India, and debate the issues and concerns faced in the practice of family therapy in India.

Change the World by Changing Economics

2014-05-01

Full Text Available We live in a world of opportunity – the opportunity to use the insight generated through the multiple crises humanity finds itself in to transit into a much more liveable, sustainable and equitable society. A paradigm change seems to be taking place, a movement for change seems to be in the making, but at the same time there is a widespread feeling that things are getting worse instead of better and there is no guarantee that change will lead us into a better future in the next few decades. To effectively guide the direction of change we need to address the root causes of today’s global challenges and take a close look at what drives human society and human beings. In doing so we realize that we are looking at a holographic picture which contains different layers, which are interdependent: Human biology; values and belief systems; the changing narrative underlying the development of human society; economics and governance and the many tools as well as special interests, support and uphold the outdated paradigms. The one element which influences all people nearly every day and is behind just about each and every crisis is the theory and practice of current economics. The article explores the debate on current economics and proposes mechanisms of change.

Desert Locusts can change reversibly between solitarious and gregarious phases, which differ considerably in behaviour, morphology and physiology. The two phases show many behavioural differences including both overall levels of activity and the degree to which they are attracted or repulsed by conspecifics. Solitarious locusts perform infrequent bouts of locomotion characterised by a slow walking pace, groom infrequently and actively avoid other locusts. Gregarious locusts are highly active with a rapid walking pace, groom frequently and are attracted to conspecifics forming cohesive migratory bands as nymphs and/or flying swarms as adults. The sole factor driving the onset of gregarization is the presence of conspecifics. In several previous studies concerned with the mechanism underlying this transformation we have used an aggregate measure of behavioural phase state, Pgreg, derived from logistic regression analysis, which combines and weights several behavioural variables to characterise solitarious and gregarious behaviour. Using this approach we have analysed the time course of behavioural change, the stimuli that induce gregarization and the key role of serotonin in mediating the transformation. Following a recent critique that suggested that using Pgreg may confound changes in general activity with genuine gregarization we have performed a meta-analysis examining the time course of change in the individual behaviours that we use to generate Pgreg. We show that the forced crowding of solitarious locusts, tactile stimulation of the hind femora, and the short-term application of serotonin each induce concerted changes in not only locomotion-related variables but also grooming frequency and attraction to other locusts towards those characteristic of long-term gregarious locusts. This extensive meta-analysis supports and extends our previous conclusions that solitarious locusts undergo a rapid behavioural gregarization upon receiving appropriate stimulation for

The anode-supported solid oxide fuel cell (SOFC) degrades when the anode is subjected to redox cycling. The degradation has qualitatively been related to microstructural changes in the nickel-yttria stabilized zirconia anode of the tested cells. In this work, the microstructural changes were...... observed in situ using environmental scanning electron microscopy. In the reduced state, a dynamic rounding of the nickel particles occurred. The oxide growth upon re-oxidation depended on the oxidation kinetics. During rapid oxidation, the NiO particles divided into 2-4 particles, which grew...... into the surrounding voids. For slower oxidation, an external oxide layer was seen to develop around the individual particles. (c) 2006 The Electrochemical Society....

Ethics as a beneficial Trojan horse in a technological society.

Queraltó, Ramón

2013-03-01

This article explores the transformation of ethics in a globalizing technological society. After describing some basic features of this society, particularly the primacy it gives to a special type of technical rationality, three specific influences on traditional ethics are examined: (1) a change concerning the notion of value, (2) the decreasing relevance of the concept of axiological hierarchy, and (3) the new internal architecture of ethics as a net of values. These three characteristics suggest a new pragmatic understanding of ethics. From a pragmatic perspective, the process of introducing ethical values into contemporary society can be regarded as a beneficial Trojan horse, a metaphor that will be developed further.

Europe's Southeastern Gateway: Responding to Rapidly Changing Patterns of World Shipping. The University's Role

Directory of Open Access Journals (Sweden)

Roger E. HAMLIN

2012-12-01

Full Text Available World trade and transportation are changing dramatically. Energy prices and transport sustainability concerns are reinvigorating ocean freighter shipping. An ever-increasing portion of trade is in containers, and container ships are getting larger quickly. Many ports, nations and continents are not keeping up with ship size increases putting them at a trade disadvantage. Major canals and seaways must also upgrade or be rendered obsolete, causing a change in the pattern of world trade. Ports have to do more than expand vessel size limits. Port regions must also invest in infrastructure that improves multi-modal access to the port and augments hand-off of containers to smaller seaway ships, trains and trucks. With heightened security and evolving emphasis on flexible and efficient logistics, ports must become high-tech logistics hubs with improved real-time data about port throughput. Constanţa, Romania provides an example of an attempt to respond to this rapid change. Near the Danube Delta, on the Black Sea, Constanţa offers a potential southeastern gateway to Europe for the Black Sea, the Eastern Mediterranean and beyond. Ships from Asia, entering via the Suez Canal can easily access Constanţa, and thus save more than ten days of shipping time for destinations in southeastern Europe compared to shipping through Rotterdam or Hamburg. But Constanţa needs to make all the improvements mentioned above. Universities have several roles in this endeavor, including identifying and forecasting trends, providing the technical knowledge to develop high-tech logistics hubs, pursing publicprivate partnerships for infrastructure development and offering training.

Intermediate steps towards the 2000-Watt society in Switzerland: an energy-economic scenario analysis

International Nuclear Information System (INIS)

Schulz, T. F.

2007-01-01

In this dissertation by Thorsten Frank Schulz the intermediate steps necessary to realise the 2000-Watt Society in Switzerland are examined. An analysis of an energy-economic scenario shows that the 2000-Watt Society should be seen as a long-term goal. According to the author, the major changes required to allow the implementation of this project concern energy-transformation and energy-demand technologies. Electricity will, according to the author, play an important role in a service-oriented society in the future. In such a transformation even intermediate steps are associated with considerable expense. The aims of the 2000-Watt Society project are listed. Energy and CO 2 balances for the domestic and transport sectors are presented and discussed. Complementary analyses are presented concerning fuel cells and wood-based fuel technologies. Finally, the implications of the 2000-Watt society and the effects of technological change are summarised and an outlook is presented

Variation in bacterial ATP concentration during rapid changes in extracellular pH and implications for the activity of attached bacteria.

Science.gov (United States)

Albert, Lynal S; Brown, Derick G

2015-08-01

In this study we investigated the relationship between a rapid change in extracellular pH and the alteration of bacterial ATP concentration. This relationship is a key component of a hypothesis indicating that bacterial bioenergetics - the creation of ATP from ADP via a proton gradient across the cytoplasmic membrane - can be altered by the physiochemical charge-regulation effect, which results in a pH shift at the bacteria's surface upon adhesion to another surface. The bacterial ATP concentration was measured during a rapid change in extracellular pH from a baseline pH of 7.2 to pH values between 3.5 and 10.5. Experiments were conducted with four neutrophilic bacterial strains, including the Gram-negative Escherichia coli and Pseudomonas putida and the Gram-positive Bacillus subtilis and Staphylococcus epidermidis. A change in bulk pH produced an immediate response in bacterial ATP, demonstrating a direct link between changes in extracellular pH and cellular bioenergetics. In general, the shifts in ATP were similar across the four bacterial strains, with results following an exponential relationship between the extracellular pH and cellular ATP concentration. One exception occurred with S. epidermidis, where there was no variation in cellular ATP at acidic pH values, and this finding is consistent with this species' ability to thrive under acidic conditions. These results provide insight into obtaining a desired bioenergetic response in bacteria through (i) the application of chemical treatments to vary the local pH and (ii) the selection and design of surfaces resulting in local pH modification of attached bacteria via the charge-regulation effect.

Obesity emergence in the Pacific islands: why understanding colonial history and social change is important.

Science.gov (United States)

McLennan, Amy K; Ulijaszek, Stanley J

2015-06-01

Between 1980 and 2008, two Pacific island nations - Nauru and the Cook Islands - experienced the fastest rates of increasing BMI in the world. Rates were over four times higher than the mean global BMI increase. The aim of the present paper is to examine why these populations have been so prone to obesity increases in recent times. Three explanatory frames that apply to both countries are presented: (i) geographic isolation and genetic predisposition; (ii) small population and low food production capacity; and (iii) social change under colonial influence. These are compared with social changes documented by anthropologists during the colonial and post-colonial periods. Nauru and the Cook Islands. While islands are isolated, islanders are interconnected. Similarly, islands are small, but land use is socially determined. While obesity affects individuals, islanders are interdependent. New social values, which were rapidly propagated through institutions such as the colonial system of education and the cash economy, are today reflected in all aspects of islander life, including diet. Such historical social changes may predispose societies to obesity. Colonial processes may have put in place the conditions for subsequent rapidly escalating obesity. Of the three frameworks discussed, social change under colonial influence is not immutable to further change in the future and could take place rapidly. In theorising obesity emergence in the Pacific islands, there is a need to incorporate the idea of obesity being a product of interdependence and interconnectedness, rather than independence and individual choice.

Communication among scientists, decision makers and society: Developing policy-relevant global climate change research

International Nuclear Information System (INIS)

Bernabo, J.C.

1995-01-01

Defining the research most relevant to policy is not simply a technical task that can be answered by scientists. Decision makers need and value information differently than curiosity-driven scientists. In order to link science more effectively to policy, the two communities must gain a greater mutual understanding. Decision makers must define their needs so that scientists can determine how, and by when, research can address these needs. This vital dialogue between communities typically has been more ad hoc than systematic. The complexity and urgency of the global climate change issue necessitate ongoing communication between scientists and decision makers on the information needed for policy development and what research can provide The results of relevant science policy dialogues are discussed herein. Effective communication between researchers and decision makers is a crucial ingredient for successfully addressing society's pressing environmental concerns. The increase in policy makers' demands for research that is relevant to solving societal issues highlights the communication gap between the technical and policy communities. The gap, largely caused by lack of mutual understanding, results in flawed and inadequate communication that hinders decision making and confuses the public. This paper examines the cause of this communication gap and describes the significance of recent efforts to develop more fruitful science-policy dialogues on the issue of global climate change. First, the post-Cold War shift in government priorities for research funding is described; then the underlying relationship between science and policy is explored to identify key sources of ongoing mis-communication. The paper then explains the importance of defining policy-relevant science questions that research can address. Finally, three projects are described involving the elicitation of decision makers' information needs in The United States, The Netherlands, and internationally

Ageing populations and changing worlds of work.

Beach, Brian

2014-08-01

Population ageing has reshaped the notion of retirement. The changes carry important implications for aspirations to extend working life. Cultural expectations regarding work and retirement must adapt to the reality posed by longer lives. The modern world is characterised by perpetual - and sometime rapid - change. Transformation throughout the second half of the 20th century brought about substantial shifts in the health and longevity of people in societies across the world. Since the beginning of the 21st century, the impacts of population ageing have gathered greater awareness in public consciousness and within the policy arena. Notions of old age, retirement, and later life have been fundamentally transformed, presenting stark challenges alongside novel opportunities for individuals, communities, and governments. Many of the topics of interest with respect to ageing populations are themselves the result of shifts that were unforeseen. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Full text: The 14 C urea breath test (CUBT) is a sensitive test used in the detection of H. pylori infection. The rapid 14 CUBT using 185 KBq of 14 C urea showed a sensitivity of 100% when tested in 36 patients. The aim of this study was to compare the results of the 14 CUBT performed following the ingestion of 37KBq microdose 14 C urea capsule (Bicapsule, Trimed) with the earlier method which uses 185 KBq 14 C urea. 19 patients (nine female age 21-52 yrs) were studied. All subjects first underwent a 14 CUBT with the microdose capsule and a single 15 minute post ingestion sample. An hour later the test was repeated but with a dose of 185 KBq 14 C urea in liquid form. A normal result was taken as 2 = 0.92). This is shown above. The Rapid 14 CUBT performed following the microdose capsule whilst reducing patient radiation exposure is an accurate test for the detection of H. pylori.

Historical earthquakes are only known to us through written recollections and so seismologists have a long experience of interpreting the reports of eyewitnesses, explaining probably why seismology has been a pioneer in crowdsourcing and citizen science. Today, Internet has been transforming this situation; It can be considered as the digital nervous system comprising of digital veins and intertwined sensors that capture the pulse of our planet in near real-time. How can both seismology and public could benefit from this new monitoring system? This paper will present the strategy implemented at Euro-Mediterranean Seismological Centre (EMSC) to leverage this new nervous system to detect and diagnose the impact of earthquakes within minutes rather than hours and how it transformed information systems and interactions with the public. We will show how social network monitoring and flashcrowds (massive website traffic increases on EMSC website) are used to automatically detect felt earthquakes before seismic detections, how damaged areas can me mapped through concomitant loss of Internet sessions (visitors being disconnected) and the benefit of collecting felt reports and geolocated pictures to further constrain rapid impact assessment of global earthquakes. We will also describe how public expectations within tens of seconds of ground shaking are at the basis of improved diversified information tools which integrate this user generated contents. A special attention will be given to LastQuake, the most complex and sophisticated Twitter QuakeBot, smartphone application and browser add-on, which deals with the only earthquakes that matter for the public: the felt and damaging earthquakes. In conclusion we will demonstrate that eyewitnesses are today real time earthquake sensors and active actors of rapid earthquake information.

Responses of temperature sensitive (cold) cells from the antenna of ground beetles (tribe Platynini) were compared in species with different ecological preferences and daily activity rhythms. Action potential rates were characterized at various temperatures (ranges 23-39 degrees C) and during rapid changes in it (Deltat=0.5-15 degrees C). The stationary firing frequencies were nearly twice as high in eurythermic open field ground beetles Agonum muelleri and Anchomenus dorsalis (firing rates ranging from 22 to 47imp/s) than in a stenothermic forest species Platynus assimilis. In the eurythermic species, the firing rate did not significantly depend on temperature (Anchomenus dorsalis range of 23-27 degrees C and Agonum muelleri range of 23-33 degrees C) but plots of firing rate versus temperature showed rapid declines when lethally high temperatures were approached. In contrast, a nearly linear decline of the firing rate/temperature curve was observed in Platynus assimilis. Responses to rapid temperature decreases were also considerably higher in eurythermic species. Both the peak frequency of the initial burst (maximum 420-650Hz) as well as the sustained discharge in the first 4s of the response were higher than in Platynus assimilis. Long silent periods, lasting up to several seconds, that occurred at the beginning of the response to rapid warming were significantly shorter in Agonum muelleri and Anchomenus dorsalis compared to Platynus assimilis. These findings suggest that the responses of thermoreceptors to temperature changes may be correlated with specific ecological preferences.

Little is known of the capacity that marine metazoans have to evolve under rapid p CO 2 changes. Consequently, we reared a marine polychaete, Ophryotrocha labronica , previously cultured for approximately 33 generations under a low/variable pH regime, under elevated and low p CO 2 for six generations. The strain used was found to be tolerant to elevated p CO 2 conditions. In generations F1 and F2 females' fecundity was significantly lower in the low p CO 2 treatment. However, from generation F3 onwards there were no differences between p CO 2 treatments, indicating that trans-generational effects enabled the restoration and maintenance of reproductive output. Whilst the initial fitness recovery was likely driven by trans-generational plasticity (TGP), the results from reciprocal transplant assays, performed using F7 individuals, made it difficult to disentangle between whether TGP had persisted across multiple generations, or if evolutionary adaptation had occurred. Nonetheless, both are important mechanisms for persistence under climate change. Overall, our study highlights the importance of multi-generational experiments in more accurately determining marine metazoans' responses to changes in p CO 2 , and strengthens the case for exploring their use in conservation, by creating specific p CO 2 tolerant strains of keystone ecosystem species.

The aim of the study was to identify mental-health-relevant literature accessible to policy makers and healthcare workers in the island nations of the Western Pacific. Material collated to support the inaugural Leadership in Mental Health: Island Nations course held in Cairns in May 2015 was used as the basis of a "rapid review". The rapid review considered 303 documents identified by a search carried out using James Cook University's OneSearch, Google Scholar, and the authors' knowledge. Search terms included mental health and the like, and terms with Pacific and current Pacific island country names. Findings were classified by region/country, year of release/publication, mental health issue addressed, peer-reviewed or grey literature, and type of study. Almost half of the findings had been released in the previous five years. However, only 36% were peer-reviewed publications and only 3.6% of the findings were intervention studies. There is limited easily accessible documentation to confidently direct practice or policies regarding which strategies are likely to be effective in responding to the high rates of mental ill-health experienced in the Pacific island nations, or to plan for increases as a consequence of rapid social and demographic changes that are transforming Pacific island societies. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Full Text Available In the context of ever increasing information dependence of all spheres of activity of the company reliability and dependability of information and communication technologies (ICT, quality of information, which is used by members of the information society, saving secrets is of paramount importance. Users must trust all information services they use. Otherwise, the consequences for society and each individual can be simply disastrous. Thus, one of the main problems of the development of the information society is to ensure the information security of the individual, society and state. In order to successfully resist the flow of threats and challenges, each member of the information society must have a certain minimum knowledge, culture and appropriate information to be prepared for an active struggle for the purity of the various types of ICT cyber-hawks, cybercriminals, cyber-terrorists and just cyber-bullies. At the same time, as shown by statistics and sociological research, while rapidly increasing the level of the use of global information and communication networks the level of information literacy of users and their information culture is extremely low. Only about 10 percent of people are more or less aware of the dangers they face while working on the Internet, or they (unwillingly is subjected to its correspondents. Thus, today the key issue of the Information Society becomes the formation of information culture of users and, above all, raising their awareness in this area. Analysis of approaches and expertise to solve this problem (especially overseas is the subject of this article.

Full Text Available Today we attend to complex changes both in economic and social field. The transition through an information society to knowledge based society, where intangible resources are more important, affects all areas of life: business, education, culture etc. In these circumstances, the information becomes a very important element, because who controls the information owns the power, especially when competition intensifies. The appearance of modern ways of communications facilitates the access to information and, in the same time, eliminates the distances. The telecommunications sector is a very dynamic one and its development is very fast. That determines us to make a short analysis of this field in Romania.

Rapid Geophysical Surveyor

1993-01-01

The Rapid Geophysical Surveyor (RGS) is a system designed to rapidly and economically collect closely-spaced geophysical data used for characterization of US Department of Energy waste sites. Geophysical surveys of waste sites are an important first step in the remediation and closure of these sites; especially older sites where historical records are inaccurate and survey benchmarks have changed because of refinements in coordinate controls and datum changes. Closely-spaced data are required to adequately differentiate pits, trenches, and soil vault rows whose edges may be only a few feet from each other. A prototype vehicle designed to collect magnetic field data was built at the Idaho National Engineering Laboratory (INEL) during the summer of 1992. The RGS was funded by the Buried Waste Integrated Demonstration program. This vehicle was demonstrated at the Subsurface Disposal Area (SDA) within the Radioactive Waste Management Complex at the INEL in September 1992. Magnetic data were collected over two areas in the SDA, with a total survey area of about 1.7 acres. Data were collected at a nominal density of 2 1/2 in. along survey lines spaced 1-ft apart. Over 350,000 data points were collected over a 6 day period corresponding to about 185 worker-days using conventional ground survey techniques

Full Text Available In the article one of the modern approaches to the social structure of the society is considered. The creative class is determined as the main driving force and as a leading social class of modern society. The author studies the history of the concept of creative class, and R. Florida’s concept in particular, and determines its characteristics and peculiarities. The influence of the creative class on the society, on its transformation processes, and the system of social values is analyzed. The role of creative class in developing creative and innovative economy of the post­industrial society era is found out. The author considers the relationship between the creative class and the other social classes of modern society. The essence of the concept of creativity is defined, and one of the most important problems of the modern era that is a constant conflict between creativity and organization is examined. The comparative historical analysis of the so­called «institutional»/ «industrial» and «creative»/ «post­industrial» era is made. The role of the creative class in developing and social changing the modern American society is studied. The questions of forming and developing creative class in modern Ukrainian society are analyzed, and the peculiarities and problems of this process are figured out. The need of state support for forming national creative class, for its strengthening and growth is emphasized.

The concentration of extracellular potassium in red blood cell concentrates (RCCs) increases during storage, leading to risk of hyperkalemia. A potassium adsorption filter (PAF) can eliminate the potassium at normal blood transfusion. This study aimed to investigate the potassium adsorption capacity of a PAF during rapid blood transfusion. We tested several different potassium concentrations under a rapid transfusion condition using a pressure bag. The adsorption rates of the 70-mEq/l model were 76·8%. The PAF showed good potassium adsorption capacity, suggesting that this filter may provide a convenient method to prevent hyperkalemia during rapid blood transfusion. © 2015 International Society of Blood Transfusion.

Structural Changes in Stx1 Engineering Monoclonal Antibody Improves Its Functionality as Diagnostic Tool for a Rapid Latex Agglutination Test

Daniela Luz

2018-02-01

Full Text Available Stx1 toxin is one of the AB5 toxins of Shiga toxin-producing Escherichia coli (STEC responsible for foodborne intoxication during outbreaks. The single-chain variable fragment (scFv is the most common recombinant antibody format; it consists of both variable chains connected by a peptide linker with conserved specificity and affinity for antigen. The drawbacks of scFv production in bacteria are the heterologous expression, conformation and stability of the molecule, which could change the affinity for the antigen. In this work, we obtained a stable and functional scFv-Stx1 in bacteria, starting from IgG produced by hybridoma cells. After structural modifications, i.e., change in protein orientation, vector and linker, its solubility for expression in bacteria was increased as well as the affinity for its antigen, demonstrated by a scFv dissociation constant (KD of 2.26 × 10−7 M. Also, it was able to recognize purified Stx1 and cross-reacted with Stx2 toxin by ELISA (Enzyme-Linked Immunosorbent Assay, and detected 88% of Stx1-producing strains using a rapid latex agglutination test. Thus, the scFv fragment obtained in the present work is a bacteria-produced tool for use in a rapid diagnosis test, providing an alternative for STEC diagnosis.

AIDS is a devastating and deadly disease that affects people worldwide and, like all infections, it comes without warning. Specifically, childbearing women with AIDS face constant psychological difficulties during their gestation period, even though the pregnancy itself may be normal and healthy. These women have to deal with the uncertainties and the stress that usually accompany a pregnancy, and they have to live with the reality of having a life-threatening disease; in addition to that, they also have to deal with discriminating and stigmatizing behaviors from their environment. It is well known that a balanced mental state is a major determining factor to having a normal pregnancy and constitutes the starting point for having a good quality of life. Even though the progress in both technology and medicine is rapid, infected pregnant women seem to be missing this basic requirement. Communities seem unprepared and uneducated to smoothly integrate these people in their societies, letting the ignorance marginalize and isolate these patients. For all the aforementioned reasons, it is imperative that society and medical professionals respond and provide all the necessary support and advice to HIV-positive child bearers, in an attempt to allay their fears and relieve their distress. The purpose of this paper is to summarize the difficulties patients with HIV infection have to deal with, in order to survive and merge into society, identify the main reasons for the low public awareness, discuss the current situation, and provide potential solutions to reducing the stigma among HIV patients.

Full Text Available The impact of globalization on contemporary post-modern society in the light of an aging population requires methods and techniques of education that are appropriate for young people and reflect (or accommodate intergenerational learning. The purpose of this paper is to analyse, through empirical research and study of literature, the context of the elderly who are too often marginalized and to show the impact of the knowledge of society based on the use of modern information and communication technologies, on intergenerational learning. The authors analyse some of the consequences of the demographic changes and highlight the role and importance of intergenerational learning and collaboration for sustainability, especially in the Slovenian ageing society. We identify the role and importance of intergenerational learning for coexistence of generations. In the analysis of the empirical data of the conducted research, we conclude that the effectiveness of the knowledge society is influenced by both: the globalization processes and the intergenerational integration, as well as (and in particular the cultural capital of younger generations and, last, but not least, the willingness of all generations to participate in the transmission and acquisition of knowledge.

Full Text Available Identification and critical study of social-political aspects of contemporary society within conditions of globalization must start from the characteristics (essence of globalization as a process of human kind consolidation. Globalization represents a process of economic, political and cultural connecting of all separate mankind societies (specific societies into the one whole, into a 'World' - 'Global' society (mega-society on the Planet with many contradictions. It is a meaningful way for money to bring profit in a peaceful manner. It leads not only to expanding of economic power through transnational and multinational economic corporations, but also to imposing way of life, social organization and categorized value system of countries - protagonists of globalization to others, as indicators of their creative capabilities and specific forms of their appearance, specialty and durability. These and other changes, as well as multiple and versatile consequences that accompany them, indicate the necessity of constructing a new social approach in their scientific cognition, with full respect of not only social but also natural laws on cognition and estimation of accomplishing social life. The social and especially sociological sciences should investigate and excogitate the next areas of global reality of contemporary society in this context. Macrostructures in the architecture of its construction: world community, socio-economic system that appears with globalization process and international community that appears by agreement between the states, their dynamic relationship and influence on flows and future of mankind civilization and social position of human. Diversity of the forms of cooperation, conflicts and collisions in the 'world' society and possibility of war conflicts regarding safety of not only specific people, regions and states, but also regarding the survival of human civilization, since it is obvious that such a conflict would have

The Nature of Society: Enmapping Nature, Space and Society into a Town-green Hybrid

Directory of Open Access Journals (Sweden)

Louis Rice

2014-10-01

Full Text Available The paper describes the transformation of derelict land into a 'town-green' and the role legislation played in transforming social and natural relationships. Town-green denotes a legal status under the Great Britain Commons Act (2006 that protects certain open spaces from building development; the status requires that a space must simultaneously have a specific social quality (i.e. 'town-ness' and a specific natural quality (i.e. 'green-ness'. This hybrid condition requires an alliance between society and nature in a certain configuration (referred to here as nature2 and society2. In this empirical study it involved the participation and consensus of local residents, volunteer gardeners as well as nature itself; flowers needed to bloom and grass had to grow in order for the hybrid town-green status to be conferred. There are two distinct phases of this transformation; the first is the change in identities and configuration of the constituents of town and green. This involved the production of a modified 'real' world with: different plants and flowers; reconfigured spatial arrangements; as well as different social actors. The second phase is a shift from changes in the "real" world towards an 'enmap' - a displacement of myriad actors into documentation. This transfer from a complex messy reality into an enmap permitted the legitimation of the new network to be accepted as a 'town-green'. What the research reveals, other than hints for gardeners and community activists, is how material and non-material; social and natural; spatial, discursive and temporal worlds are hybridised.

The western honey bee, Apis mellifera, is an enormously influential pollinator in both natural and managed ecosystems. In North America, this species has been introduced numerous times from a variety of different source populations in Europe and Africa. Since then, feral populations have expanded into many different environments across their broad introduced range. Here, we used whole genome sequencing of historical museum specimens and newly collected modern populations from California (USA) to analyze the impact of demography and selection on introduced populations during the past 105 years. We find that populations from both northern and southern California exhibit pronounced genetic changes, but have changed in different ways. In northern populations, honey bees underwent a substantial shift from western European to eastern European ancestry since the 1960s, whereas southern populations are dominated by the introgression of Africanized genomes during the past two decades. Additionally, we identify an isolated island population that has experienced comparatively little change over a large time span. Fine-scale comparison of different populations and time points also revealed SNPs that differ in frequency, highlighting a number of genes that may be important for recent adaptations in these introduced populations. © The Author(s) 2018.

Full Text Available In contemporary societies, through the advances in the technologies of informatics and communication, global interactions are increased, and developments, variations, changes, and transformations in any field are shared more rapidly than at any previous time in human history. Existing systems have been unable to show the necessary flexibility regarding the new requirements and the problems of new relations due to unpredictable circumstances. This can lead to the perception of chaotic societies and cause ontological problems in planning, which is based on future predictions. The main goal of this paper is to summarize the “synergetic society model”, “synergic administration” and “synergistic planning approaches” (developed for the dissertation. These concepts will help us to understand uncertain and unpredictable social changes. According to our model, “social synergy”, which is spontaneously emerging and organizing via communication channels, is thoroughly examined in the processes of chaos and self-organization as experienced following the eastern Marmara earthquake in 1999. The building process of a primary school with the help of social synergy in Kılıçköy / Yalova after the earthquake is explained on the basis of communication channels between different levels and with varying dynamics.

A transition from analogue to computer based I and C (instrumentation and control) systems in nuclear power plants enabled the industry not only to make use of advantages of computers for the control of technological processes, but also transferred the unusual short innovation cycles in computer technology to become a constraint on the process I and C. This situation led the IAEA to provide an international forum for the presentation and discussion of the problems and organize a Specialists` Meeting in the framework of the International Working Group on Nuclear Power Plant Control and Instrumentation. The basic objective was to elaborate the management, engineering and economic problems arising from rapid technological changes, to point out solutions and to discuss the future trends in the field. The Year 2000 Issue was also inside the scope of the Meeting. Typical problems were technology changes provoking major I and C concept changes, spare part availability, compatibility in refurbishment processes.

Malaysian government aims to reduce 40% reduction of carbon emission intensity by the year 2020 using 2005 as the base year. Several mitigation and adaptation strategies in addressing environmental and climate change are formulated at national, regional and local level to mitigate greenhouse gases. This paper aims to examine local and regional resilient policy actions to reduce greenhouse gases using the empirical case of Iskandar Malaysia. The study case is selected because it is one of the fast developing economic corridor regions in Malaysia. In this study, a low carbon society blueprint is initiated to guide the rapid development of this economic corridor towards low carbon green growth. The blueprint provides the sustainable green growth roadmap with major 12 actions for the region. It is done through a bottom-up approach where stakeholder discussions are carried out to allow local communities participation in the plan formulation.

1995-01-01

Isotopic exchange of protein backbone amide hydrogens has been used extensively as a sensitive probe of protein structure. One of the salient features of hydrogen exchange is the vast range of exchange rates in one protein. Isotopic exchange methods have been used to study the structural features including protein folding and unfolding (1), functionally different forms of proteins (2), protein-protein complexation (3), and protein stability parameter. Many backbone amide protons that are surface accessible and are not involved in hydrogen bonding undergo rapid deuterium exchange. In order to study, fast exchanging amide protons, fast exchange-in times are necessary

2013-01-01

The last major advance in gas content measurement for coal seams was the introduction of the quick crush technique in the early 1990s. This is a laboratory test method that has proven very reliable over the years. Recent laboratory testing using a portable quick crushing device, known as the portable gas content analyser, has produced consistent gas content results for a set of core samples obtained from a single borehole that intersected four coal seams. The retained gas content values obtained for the seams show the same increasing gas content pattern and gas composition change with depth as the standard quick crush technique. Use of the portable gas content analyser provides the opportunity to produce rapid, reliable gas content measurement of coal that could be developed for assessing gas compliance cores and outburst-prone conditions at a mine site.

Regarding Societal Change

Full Text Available In this paper we introduce our special thematic section on societal change. We begin by providing an overview of the aims of the section, and how these aims grew out of a need to address conceptual and empirical challenges in the study of societal change. In response to these challenges, the section was intended to provide a forum for theoretical and empirical work from a range of disciplinary perspectives on how societies change, and how such change can be understood. Together, the contributions argue for (1 the need to contextualize the study of societal change, (2 the value of considering factors and processes other than collective action in transforming societies, (3 the importance of ideology and its operation through social institutions such as news media, and (4 an imperative to ensure that our research is fully engaged with society in terms of its grounding in social issues, its sensitivity to our own social context as researchers, and in its practices and outcomes.

The University of Vermont College of Medicine and the Vermont Lung Center, in collaboration with the NHLBI, Alpha-1 Foundation, American Thoracic Society, European Respiratory Society, International Society for Cell Therapy, and the Pulmonary Fibrosis Foundation, convened a workshop, "Stem Cells and Cell Therapies in Lung Biology and Lung Diseases," held July 29 to August 1, 2013 at the University of Vermont. The conference objectives were to review the current understanding of the role of stem and progenitor cells in lung repair after injury and to review the current status of cell therapy and ex vivo bioengineering approaches for lung diseases. These are all rapidly expanding areas of study that both provide further insight into and challenge traditional views of mechanisms of lung repair after injury and pathogenesis of several lung diseases. The goals of the conference were to summarize the current state of the field, discuss and debate current controversies, and identify future research directions and opportunities for both basic and translational research in cell-based therapies for lung diseases. This conference was a follow-up to four previous biennial conferences held at the University of Vermont in 2005, 2007, 2009, and 2011. Each of those conferences, also sponsored by the National Institutes of Health, American Thoracic Society, and Respiratory Disease Foundations, has been important in helping guide research and funding priorities. The major conference recommendations are summarized at the end of the report and highlight both the significant progress and major challenges in these rapidly progressing fields.

Rapid realist review of the evidence: achieving lasting change when mental health rehabilitation staff undertake recovery-oriented training.

The aim of this study was to identify the factors contributing to lasting change in practice following a recovery-based training intervention for inpatient mental health rehabilitation staff. Staff training may help nurses and other staff groups in inpatient mental health rehabilitative settings to increase their recovery-oriented practice. There are no published reviews on the effectiveness of such training and few long-term evaluations. This review informed a realist evaluation of a specific intervention (GetREAL). Rapid realist review methodology was used to generate and prioritize programme theories. ASSIA, CINAHL, Cochrane Library, Medline, PsycINFO, Scopus, Web of Science and grey literature searches were performed in September 2014-March 2015 with no date restrictions. Stakeholders suggested further documents. GetREAL project documentation was consulted. Programme theory development took place iteratively with literature identification. Stakeholders validated and prioritized emerging programme theories and the prioritized theories were refined using literature case studies. Fifty-one relevant documents fed into 49 programme theories articulating seven mechanisms for lasting change. Prioritized mechanisms were: staff receptiveness to change; and staff feeling encouraged, motivated and supported by colleagues and management to change. Seven programme theories were prioritized and refined using data from four case studies. Lasting change can be facilitated by collaborative action planning, regular collaborative meetings, appointing a change agent, explicit management endorsement and prioritization and modifying organizational structures. Conversely, a challenging organizational climate, or a prevalence of 'change fatigue', may block change. Pre-intervention exploration may help identify any potential barriers to embedding recovery in the organizational culture. © 2016 John Wiley & Sons Ltd.

The need for interaction between assisted reproduction technology and genetics: recommendations of the European Societies of Human Genetics and Human Reproduction and Embryology.

Science.gov (United States)

2006-08-01

Infertility and reproductive genetic risk are both increasing in our societies because of lifestyle changes and possibly environmental factors. Owing to the magnitude of the problem, they have implications not only at the individual and family levels but also at the community level. This leads to an increasing demand for access to assisted reproduction technology (ART) and genetic services, especially when the cause of infertility may be genetic in origin. The increasing application of genetics in reproductive medicine and vice versa requires closer collaboration between the two disciplines. ART and genetics are rapidly evolving fields where new technologies are currently introduced without sufficient knowledge of their potential long-term effects. As for any medical procedures, there are possible unexpected effects which need to be envisaged to make sure that the balance between benefits and risks is clearly on the benefit side. The development of ART and genetics as scientific activities is creating an opportunity to understand the early stages of human development, which is leading to new and challenging findings/knowledge. However, there are opinions against investigating the early stages of development in humans who deserve respect and attention. For all these reasons, these two societies, European Society of Human Genetics (ESHG) and European Society of Human Reproduction and Embryology (ESHRE), have joined efforts to explore the issues at stake and to set up recommendations to maximize the benefit for the couples in need and for the community.

Russian science trapped in web of rapid change

International Nuclear Information System (INIS)

Josephson, P.R.

1995-01-01

During the Cold War, Soviet physicists were revered for their contribution to the country's prestige, economic growth, and national security, says Paul Josephson, a professor in the Department of Science, Technology, and Society at Sarah Lawrence College in Bronxville, New York. But the lavish support the Russian physics establishment once received is gone. In fact, the dissolution of the Soviet regime and deepening economic and political crisis have left scientists struggling to maintain their programs and keep institutes open. Internal crisis and the internationalization of science and technology have led to a drain of top Russian scientists in many fields, particularly in mathematics and theoretical physics. The West has responded to these concerns by giving financial aid and sponsoring initiatives designed to keep former Soviet scientists employed either at home or in the United States or Europe. However, the ultimate health of Russian science will depend on internal government reforms and public support, concludes Josephson

The role of civil society in health policy making in South Africa: a review of the strategies adopted by the Treatment Action Campaign.

Science.gov (United States)

Sabi, Stella C; Rieker, Mark

2017-03-01

The diagnosis of AIDS in 1982 in South Africa was followed by a rapid rise in the number of people living with the virus and dying from AIDS-related illnesses. The 2016 report by the Statistics South Africa indicated that about 7.03 million South Africans were infected with HIV/AIDS - the highest rate in the world. Despite the emergence of effective drugs in the mid-1990s, medical treatment remained unavailable in South Africa, particularly in public hospitals. This prompted civil society groups to establish platforms to discuss health policy change in South Africa. Prominent among these was the Treatment Action Campaign (TAC), formed in 1998, which aimed to advocate for improved HIV/AIDS health service delivery. The efforts succeeded in shaping the current HIV/AIDS policy through various initiatives such as the use of constitutional law in legal action against profiteering drug companies. This paper examines the role of civil society, and particularly the TAC engagement with the state in health policy making, and the subsequent implementation of health policy on HIV/AIDS in post-apartheid South Africa.
